(1) Purchases of $1,000,000 or more and purchases by participants in a Group 
    Plan (as described under "How to Purchase Shares") are not subject to an 
    initial sales charge. A contingent deferred sales charge of 0.50% may, 
    however, be charged on redemptions by such accounts of shares held less 
    than one year, as further described under "Redemptions and Repurchases." 
(2) Separate fees (currently $10 and $20) apply to domestic or international 
    bank wire transfers, respectively, of redemption proceeds. 
(3) Effective February 1, 1994, the Funds' investment adviser, Pioneering 
    Management Corporation ("PMC"), voluntarily agreed not to impose a 
    portion of its management fees and to limit or otherwise absorb other 
    operating expenses except taxes and interest on borrowed money, if any, 
    in accordance with the following schedule: 

                        Expense limit as a percent 
      Net Assets       of average daily net assets 
 --------------------- --------------------------- 
Up to $20 million                  0.50% 
Up to $25 million                  0.55% 
Up to $30 million                  0.60% 
Up to $35 million                  0.65% 
Up to $40 million                  0.70% 
Over $40 million                   0.75% 
    

  This agreement is voluntary and temporary and may be revised or terminated 
  at any time by PMC. The purpose of this policy is to enhance each Fund's 
  dividend yield during the period when, because of their smaller size, fixed 
  expenses have a more significant impact on yield.

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

Ten Years           $96        $96         $96 

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

   The example is designed for information purposes only, and should not be 
considered a representation of past or future expenses or return. Actual Fund 
expenses and returns 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 Funds, including information regarding the basis upon which 
fees and expenses are reduced or reallocated, see "Management of the Trust," 
"Distribution Plan" and "How To Purchase Shares" in this Prospectus and 
"Management of the Trust" and "Underwriting Agreement and Distribution Plan" 
in the Statement of Additional Information. The Fund's payment of a Rule 
12b-1 fee may result in long-term shareholders indirectly paying more than 
the economic equivalent of the maximum sales charge permitted under the Rules 
of Fair Practice of the National Association of Securities Dealers, Inc. 
("NASD"). 

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

IV. THREE INVESTMENT PROGRAMS 

Investment Objectives and Policies 
   The investment objective of each Fund is to provide as high a level of 
current income exempt from federal income taxes and from the personal income 
taxes of its respective state, and, if applicable, city, as is consistent 
with prudent investment risk. 
   As a matter of fundamental policy, under normal circumstances each Fund 
invests at least 80% of its net assets in securities the interest income on 
which is exempt from federal and its respective state's personal income taxes 
and, if applicable, city income taxes. These securities include municipal 
bonds and notes and other debt instruments issued by or on behalf of the 
Fund's respective state and such state's political subdivisions, agencies and 
instrumentalities, including variable and floating rate obligations, and 
similar obligations issued by the governments of Puerto Rico, Guam and the 
United States ("U.S.") Virgin Islands. The remainder of each Fund's assets 
may be invested in Other Eligible Investments as described below. Securities 
whose interest income is an item of tax preference under the federal 
alternative minimum tax will not be considered exempt from federal income tax 
for purposes of the 80% policy set forth above; however, the Funds do not 
currently intend to invest any of their assets in such securities. 
   Municipal bonds include general obligation bonds and revenue bonds. 
General obligation bonds are backed by the taxing power of the issuing 
municipality and are considered the safest type of bonds. Revenue bonds are 
backed by the revenues of a project or facility such as the tolls from a toll 
bridge. Municipal notes include bond anticipation notes, tax anticipation 
notes, revenue anticipation notes, and construction loan notes. Bond, tax and 
revenue anticipation notes are short-term obligations that will be retired 
with the proceeds of an anticipated bond issue, tax revenue or facility 
revenue, respectively. Construction loan notes are short-term obligations 
that will be retired with the proceeds of long-term mortgage financing. In 
acquiring municipal obligations, the Funds will rely upon an opinion of 
counsel of the issuer to the effect that interest on the obligation is 
excluded from gross income for federal income tax purposes, and, if 
applicable, exempt from personal income taxes of the applicable state and its 
political subdivisions. 
   Each Fund may invest in variable rate and floating rate obligations the 
interest on which may fluctuate based on changes in market rates. The 
interest rates payable on variable rate obligations are adjusted at 
designated intervals. The interest rates payable on floating rate obligations 
are adjusted whenever there is a change in the market rate of interest on 
which the interest payable is based. The value of floating and variable rate 
obligations generally is more stable than that of fixed rate obligations in 
response to changes in interest rate levels. Each Fund may consider the 
maturity of a variable or floating rate municipal obligation to be shorter 
than its ultimate maturity if the Fund has the right to demand prepayment of 
its principal at specified intervals prior to the security's ultimate 
maturity. Each Fund may purchase certificates of participation, a type of 
floating or variable rate obligation, which are interests in a pool of 
municipal obligations held by a bank. 

Quality and Maturity of Investments 
   Each of the Funds invests only in investment grade securities, which are 
securities rated at the time of purchase within the top four grades by one or 
more of the major rating services (i.e. "Baa" or higher by Moody's Investor 
Services ("Moody's"), or "BBB" or higher by Standard & Poor's Ratings Group 
("S&P")) or, if not rated, judged to be of comparable quality by the Funds' 
investment adviser. Each Fund may invest up to 25% of its assets in unrated 
securities and securities rated in the fourth highest grade. Obligations in 
the lowest investment grade (Baa and BBB) have speculative characteristics, 
and changes in economic conditions and other factors are more likely to lead 
to a weakened capacity to pay principal and interest on these obligations 
than is the case for higher rated obligations. If an obligation purchased by 
a Fund is subsequently downgraded below investment grade the Fund may retain 
such obligation until the adviser considers it prudent to dispose of it. 
However, at no time may any Fund have more than 5% of its net assets invested 
in securities rated below investment grade. Some securities owned by a Fund 
may be insured by or backed by a letter of credit issued by a third party in 
which case credit ratings and the ability to pay interest and repay principal 
may depend on the third party's ability to meet its obligations. For a 
description of Moody's and S&P's ratings of municipal bonds see Appendix B to 
the Funds' Statement of Additional Information. 
   The Funds have no restrictions on portfolio maturity but the dollar 
weighted average maturity of each Fund's portfolio is expected to be between 
15 and 25 years. 
    

   
Other Eligible Investments 
   Under normal circumstances, each Fund may invest up to 20% of its net 
assets in Other Eligible Investments. Other Eligible Investments consist of 
(a) investment grade debt securities the interest on which is exempt from 
federal income taxes, but not personal income taxes of a Fund's respective 
state and, if applicable, city; (b) corporate commercial paper and other 
short-term commercial obligations rated Prime-1 or MIG-1 by Moody's or A-1 or 
AAA by S&P; (c) obligations of banks (including certificates of deposit, 
banker's acceptances and repurchase agreements) with $1 billion or more of 
assets; (d) obligations issued or guaranteed by the U.S. Government. 
   The Funds intend to minimize the distribution of taxable income to 
shareholders, and investment in securities the 
    


                                      4 

<PAGE>
 
interest on which is subject to federal income tax or the personal income 
taxes of a Fund's respective state and, if applicable, city will generally be 
made only to meet short term liquidity needs. If a Fund cannot find suitable 
federal and state tax exempt securities for investment, investments will 
generally be made in securities the interest on which is exempt from federal 
income taxes but not the income taxes of the Fund's respective state and, if 
applicable, city. However, a portion of the dividends distributed to 
shareholders may be subject to state, or federal and state, income taxes. As 
a temporary defensive measure during times of adverse market conditions, each 
Fund may invest up to 50% of its assets in the Other Eligible Investments 
described above. 

"When Issued" Securities 
   The Funds may purchase municipal securities on a "when issued" basis, 
which means it may be 60 days or more before the securities are delivered and 
paid for. The price and yield of the securities so purchased are generally 
fixed on the date of purchase commitment. However, the market value of the 
securities may fluctuate prior to delivery, and upon delivery the securities 
may be worth more or less than the Fund agreed to pay for them. Purchases of 
securities on a "when issued" basis may involve more risk than other types of 
purchases. The Funds will maintain in segregated accounts sufficient assets 
to cover their purchase obligations so long as such obligations continue. 

Puts, Demand Features and Standby Commitments 
   In order to enhance the liquidity, stability or quality of a municipal 
obligation, each Fund may acquire the right to sell the security to another 
party for a guaranteed price and term. These rights may be referred to as 
puts, demand features or standby commitments. 

Fluctuations in Net Asset Value and Income 
   The net asset values of the shares of the series of an open-end investment 
company such as the Trust, which invests primarily in fixed-income tax-exempt 
securities, will fluctuate as the general levels of interest rates fluctuate. 
When interest rates rise, the net asset value of a Fund invested at lower 
yields can be expected to decline. Furthermore, the tax-exempt income 
provided by a Fund will fluctuate over time. For a description of how to 
compare yields on municipal bonds and taxable securities, see "Taxable 
Equivalent Yields" in the Appendix. 

Portfolio Transactions and Turnover 
   The Funds will be fully managed by purchasing and selling securities, as 
well as holding selected securities to maturity. In purchasing and selling 
portfolio securities, each Fund seeks to take advantage of market 
developments, yield disparities and variations in the creditworthiness of 
issuers. 
   While it is not possible to predict accurately the rate of turnover of 
each Fund's portfolio on an annual basis, it is anticipated that the rate 
will not exceed 85%. A portfolio turnover of 85% would occur if 85% of the 
securities in the portfolio were changed once in a twelve-month period. 
Computation of portfolio turnover excludes transactions in U.S. Treasury 
obligations and securities having a maturity of one year or less from 
purchase date. 
   The investment objective of each Fund is fundamental and may not be 
changed by the Board of Trustees without shareholder approval. Because all of 
the Funds' investments are subject to fluctuations in yields and value due to 
changes in earnings, economic conditions and other factors, there can be no 
assurance that any Fund's investment objective will be achieved. 
   The Statement of Additional Information includes a discussion of other 
investment policies and a listing of specific investment restrictions which 
govern each Fund's investment policies. The specific investment restrictions 
identified in the Statement of Additional Information as fundamental may not 
be changed without shareholder approval. If a percentage restriction or a 
rating restriction on investments or utilization of assets is adhered to at 
the time an investment is made or assets are so utilized, except in the case 
of borrowings, a later change in percentage resulting from changes in the 
value of a Fund's securities or from a change in the rating of a portfolio 
security will not be considered a violation of policy. 

   
Special Risk Considerations 
   Because each of the Funds is non-diversified and will concentrate 
investments in securities issued by specific states (California, New York and 
Massachusetts) and their political subdivisions and instrumentalities, each 
Fund is more susceptible to economic and other factors adversely affecting 
these issuers than funds which are diversified or otherwise do not 
concentrate in specific states. As a result, the value of each Fund's shares 
may fluctuate more widely than the value of shares of a portfolio investing 
in securities relating to a number of different states. The ability of state, 
county, or local governments to meet their obligations will depend primarily 
on the availability of tax and other revenues to those governments and on 
their fiscal conditions generally. The amounts of tax and other revenues 
available to governmental issuers of tax-exempt securities may be affected 
from time to time by economic, political, and demographic conditions within 
the particular state. In addition, constitutional or statutory restrictions 
may limit a government's power to raise revenues or increase taxes. The 
availability of federal, state, and local aid to issuers of tax-exempt 
securities may also affect their ability to meet their obligations. Payments 
of principal and interest on limited obligation securities will depend on the 
economic condition of the facility or specific revenue source from whose 
revenues the payments will be made, which in turn could be affected by 
economic, political, and demographic conditions in the particular state. Any 
reduction in the actual or perceived ability of an issuer of tax-exempt 
securities to meet its obligations (including a reduction in the rating of 
its outstanding securities) would likely affect adversely the market value 
and marketability of its obligations and could affect adversely the values of 
other tax- exempt securities as well. 
   In addition, none of these Funds is a diversified fund (except to the 
extent that diversification is required for federal income tax purposes). For 
these tax purposes, with respect to 50% of the value of its total assets, 
none of these Funds invests more than 5% of the value of its total assets in 
securities of a single issuer (except U.S. Government securities or 
    


                                      5 

<PAGE>
 
securities of other regulated investment companies), nor, with respect to the 
other 50% of the value of its total assets, does it invest more than 25% of 
the value of its total assets in the securities of a single issuer (except 
U.S. Government securities or securities of other regulated investment 
companies). Because they may invest a larger percentage of their assets in 
the securities of fewer issuers than do diversified funds, the Funds may be 
exposed to greater risk because an adverse change in the condition of one or 
a small number of issuers would have a greater impact on them. 
   Each of the Funds may also invest in obligations of U.S. possessions and 
territories, such as those of the governments of Puerto Rico, the U.S. Virgin 
Islands and Guam, to the extent that interest payments on these obligations 
are exempt from personal income taxes of their respective state or city. 
Under normal circumstances, however, no Fund will invest more than 35% of its 
total assets in obligations of such possessions and territories in the 
aggregate, or more than 5% of its net assets in the obligations of each of 
the U.S. Virgin Islands and Guam. In particular, the Funds may be adversely 
affected by local political and economic conditions and developments within 
Puerto Rico adversely affecting the issuers of such obligations. The essence 
of Puerto Rico's credit quality is the stability it derives from its 
economic, political and social ties to the United States, which mitigate the 
relatively weak underlying credit fundamentals. Puerto Rico receives 
significant economic benefits from Section 936 of the Internal Revenue Code 
of 1986, as amended (the "Code") which confers significant tax credits upon 
U.S. corporations doing business in Puerto Rico. The U.S. is its primary 
trading partner. The U.S. has provided further economic incentives through 
the Caribbean Basin Initiative, which is designed to further U.S. economic 
and political interests in the region. 
   Because of perceived abuses by certain corporations and the resultant 
revenue loss of the federal government, Section 936 has been continually 
under attack in the U.S. Congress. Should Puerto Rico achieve statehood, 
Section 936 would be repealed or cease to apply. The effects of a repeal of 
Section 936 as a result of statehood or otherwise would include: higher 
unemployment, reduction in Puerto Rico's Gross Domestic Product and a decline 
in investment by U.S. companies in Puerto Rico. As a result of the North 
American Free Trade Agreement, the higher cost of labor in Puerto Rico 
relative to other countries in the region, such as Mexico, provides a 
disincentive to U.S. companies considering locating operations in Puerto 
Rico. 
   Each Fund may also invest 25% or more of the value of its total assets in 
municipal obligations in its respective state which obligations are related 
in such a way that an economic, business or political development or change 
affecting one municipal obligation would also affect the other municipal 
obligations. For example, a Fund may so invest in municipal obligations the 
interest on which is paid solely from revenues of similar projects such as 
hospitals, electric utility systems, multi-family housing, nursing homes or 
life care facilities. This fact makes the Funds more susceptible to adverse 
factors affecting one or more of these projects than a fund that does not 
concentrate its investments to this degree. 

   
V. MANAGEMENT OF THE TRUST 
   The Trust's Board of Trustees has overall responsibility for management 
and supervision of the Funds. There are currently eight Trustees, six of whom 
are not "interested persons" of the Trust 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 Pioneering Management 
Corporation ("PMC" or the "Manager") as investment adviser, the Trust 
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 Trust. 
   The Trust is managed under a contract with PMC. PMC serves as investment 
adviser to the Trust and is responsible for the overall management of the 
Trust'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 Funds. 
   Each fixed income portfolio managed by PMC, including these Funds, is 
overseen by a Fixed Income Committee, which consists of PMC's most senior 
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 Funds, are 
under the general supervision of Mr. Sherman Russ, Senior Vice President of 
PMC. Mr. Russ joined PMC in 1983. 
   Day-to-day management of the Trust has been the responsibility of Ms. 
Kathleen McClaskey, Vice President of the Trust and PMC. Ms. McClaskey joined 
Pioneer in 1986 and has been primarily responsible for the Trust since its 
inception. In certain instances where Ms. McClaskey is unavailable, primary 
responsibility for the day-to-day management of the Trust may be temporarily 
assumed by Mr. Mark Winter. Mr. Winter joined PMC in 1993 and is primarily 
responsible for Pioneer Tax-Free Income Fund. 
   In addition to the Trust, 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 Trust, PMC assists in the 
management of the Trust and is authorized in its discretion to buy and sell 
securities for the account of each Fund in the Trust, subject to the right of 
the Trustees to disapprove any such purchase or sale. PMC pays all the 
ordinary operating expenses, including executive salaries and the rental of 
office space relating to its services for the Trust, with the exception of 
the following which are to be paid by the Trust: (a) taxes and other 
governmental charges, if any; (b) interest 
    


                                      6 

<PAGE>
 
   
on borrowed money, if any; (c) legal fees and expenses; (d) auditing fees; 
(e) insurance premiums; (f) dues and fees for membership in trade 
associations; (g) fees and expenses of registering and maintaining 
registrations of the Trust and the shares of each of its Funds with the SEC, 
individual states, territories and foreign jurisdictions and of preparing 
reports to government agencies; (h) fees and expenses of Trustees not 
affiliated with or interested persons of PMC; (i) fees and expenses of the 
custodian, dividend disbursing agent, transfer agent and registrar; (j) issue 
and transfer taxes chargeable to the Trust in connection with securities 
transactions to which the Trust is a party; (k) costs of reports to 
shareholders, shareholders' meetings and Trustees' meetings; (l) the cost of 
certificates representing shares of the fund; (m) bookkeeping and appraisal 
charges; and (n) distribution fees in accordance with Rule 12b-1. Each Fund 
also pays all brokerage commissions in connection with its portfolio 
transactions. 
   Orders for each 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 management fee equal to 0.60% per annum of each 
Fund's average daily net assets. The fee is normally computed daily and paid 
monthly. PMC has agreed temporarily not to impose any management fee and to 
limit each Fund's expenses. See "Expense Information," above. 
   John F. Cogan, Jr., Chairman and President of the Trust, 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. 
    

VI. DISTRIBUTION PLAN 
   The Trust has adopted a Plan of Distribution (the "Distribution Plan") in 
accordance with Rule 12b-1 under the 1940 Act pursuant to which certain 
distribution fees of each Fund are paid to PFD. 
   Pursuant to the Distribution Plan, each Fund shall reimburse PFD for its 
actual expenditures to finance any activity primarily intended to result in 
the sale of Fund shares or to provide services to Fund shareholders, provided 
the categories of expenses for which reimbursement is made are approved by 
the Trust's Board of Trustees. As of the date of this Prospectus, the Board 
of Trustees has approved the following categories of expenses for the Funds: 
(i) a service fee (sometimes referred to as a "trail commission") to be paid 
to qualified broker-dealers in an amount not to exceed 0.25% per annum of a 
Fund's average daily net assets; (ii) reimbursement to PFD or PMC for its 
expenditures for broker-dealer commissions and employee compensation on 
certain sales of a Fund's shares with no initial sales charge (see "How to 
Purchase Shares"); and (iii) reimbursement to PFD for expenses incurred in 
providing services to shareholders and supporting broker-dealers and other 
organizations (such as banks and trust companies) in their efforts to provide 
such services. Banks are currently prohibited under the Glass-Steagall Act 
from providing certain underwriting or distribution services. If a bank was 
prohibited from acting in any capacity or providing any of the described 
services, management would consider what action, if any, would be 
appropriate. 
   Total expenses under the Distribution Plan may not exceed 0.25% of average 
daily net assets. Distribution expenses of PFD are expected to substantially 
exceed the distribution fees paid by a Fund in a given year. The Distribution 
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 affected 
thereby. 
   The Distribution Plan does not provide for the carryover of reimbursable 
expenses beyond 12 months from the time they are incurred. The limited 
carryover provision in the Plan may result in an expense invoiced to a 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 Distribution Plan, a Fund may 
nevertheless, within 12 months of such termination or non-continuance 
reimburse any expense which it incurs prior to such termination or non- 
continuance, provided that payments by the Fund during such 12-month period 
shall not exceed 0.25% of the Fund's average daily net assets during such 
period. 

   
VII. INFORMATION ABOUT SHARES 
How to Purchase Shares 
   You may purchase shares of any of the Funds in the trust from any 
securities broker-dealer which has a sales agreement with PFD. If you do not 
have a securities broker-dealer, please call 1-800-225-6292. Shares will be 
purchased at the public offering price, that is, the net asset value per 
share plus any applicable sales charge, next computed after receipt of a 
purchase order, except as set forth below. 
   The minimum initial investment is $1,000, except for accounts being 
established to utilize monthly bank drafts, government allotments and other 
similar automatic investment plans. The minimum investment for such plans, as 
well as all other subsequent additions to an account, is $50. No sales charge 
or minimum investment requirements apply to the reinvestment of dividends or 
capital gains distributions. 
   Telephone Purchases. Your account is automatically authorized to have the 
telephone purchase privilege unless you indicated otherwise on your Account 
Application or by writing to Pioneering Services Corporation ("PSC"). The 
telephone purchase option may be used to purchase additional shares for an 
existing mutual fund account; it may not be used to establish a new account. 
Proper account identification will be required for each telephone purchase. A 
maximum of $25,000 per account may be purchased by telephone each day. 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 
    

                                      7 

<PAGE>
 
   
account of record by completing the appropriate section of your Account 
Application or an Account Options Form. PSC will electronically debit the 
amount of each purchase from this predesignated bank account. Telephone 
purchases may not be made for 30 days after the establishment of your bank of 
record or any change to your bank information. 
   Telephone purchases will be priced at the net asset value plus any 
applicable sales charge next determined after PSC's 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. 
   The public offering price is the net asset value per share next computed 
after receipt of a purchase order, plus a sales charge as follows: 
    

                                    Sales Charge as a % of    Dealer 
                                    -----------------------  Allowance

                                    Offering     Amount      Offering 
        Amount of Purchase           Price      Invested       Price

$1,000,000 or more                     -0-         -0-       see below 

   
   No sales charge is payable at the time of purchase on investments of 
$1,000,000 or more, or for investments by certain group plans with 100 or 
more participants or at least $500,000 in plan assets ("Group Plans"), but 
for such investments a contingent deferred sales charge ("CDSC") of 0.50% is 
imposed in the event of certain redemption transactions within one year of 
purchase. See "Redemptions and Repurchases" below. PFD may, in its 
discretion, pay a commission to broker-dealers who initiate and are 
responsible for such purchases as follows: 0.50% on sales of $1 million to $5 
million; and 0.10% on the excess over $5 million. These commissions shall not 
be payable if the purchaser is affiliated with the broker-dealer or if the 
purchase represents the reinvestment of a redemption made during the previous 
twelve calendar months. See also "Redemptions and Repurchases." In connection 
with PGI's acquisition of Mutual of Omaha Fund Management Company and 
contingent upon the achievement of certain sales objectives, PFD may pay to 
Mutual of Omaha Investor Services, Inc. 50% of PFD's retention of any sales 
commission on sales of the Funds' shares through such dealer. Shares sold 
outside the U.S. to persons who are not U.S. citizens may be subject to 
different sales charges, CDSC's and dealer compensation arrangements in 
accordance with local laws and business practices. 
   The schedule of sales charges above is applicable to purchases of shares 
of a Fund by (i) an individual, (ii) an individual, his or her spouse and 
children under the age of 21 and (iii) a trustee or other fiduciary of a 
trust, estate or fiduciary account or related trusts or accounts. 
   The sales charge applicable to a current purchase of shares of a Fund by a 
person listed above is determined by adding the value of shares to be 
purchased to the aggregate value (at current offering price) of shares of any 
of the 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 so qualify. For purposes of the preceding sentence, 
Pioneer mutual funds include all mutual funds for which PFD serves as 
principal underwriter. For example, a person investing $5,000 in a Fund who 
currently owns shares of the Pioneer mutual funds with a value of $100,000 
would pay a sales charge of 2.5% of the offering price on the new investment. 
   Sales charges may also be reduced through an agreement to purchase a 
specified quantity of shares over a designated 13-month period by completing 
the "Letter of Intention" section of the Account Application. Information 
about the Letter of Intention procedure, including its terms, is contained on 
the back of the Account Application as well as 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 a Fund at net asset value, 
without a sales charge, to the extent that the purchase price is paid out of 
the 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 a Fund; that the client paid a sales charge on the original 
purchase of the shares redeemed; and that the mutual fund whose shares were 
redeemed also offers net asset value purchases to redeeming shareholders of 
any of the Pioneer mutual funds. Further details may be obtained from PFD. 
   Shares of a Fund may be sold at a reduced or eliminated sales charge to 
certain Group Plans under which a sponsoring organization makes 
recommendations to permit group solicitation of, or otherwise facilitates 
purchases by, its employees, members or participants. Information about such 
arrangements is available from PFD. 
   Shares of a 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 Trust and 
partners and employees of its legal counsel; (b) current or former directors, 
officers, employees or sales representatives of PGI, its subsidiaries; (c) 
current or former directors, officers, employees or sales representatives of 
any subadviser or predecessor investment adviser to any investment company of 
which PMC serves as investment adviser, and the subsidiaries or affiliates of 
such persons; (d) current or former officers, partners, employees or 
registered representatives of broker-dealers which have entered into sales 
agreements with PFD; (e) members of the immediate families of any of the 
persons listed above; (f) any trust, custodian, pension, profit-sharing or 
other benefit plan of the persons listed above; (g) insurance company 
separate accounts; (h) certain "wrap accounts" for the benefit of clients of 
investment advisers 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 a Fund may also be sold at net 
asset value with- 
    


                                      8

out a sales charge in connection with certain reorganization, liquidation or 
acquisition transactions involving other investment companies or personal 
holding companies. 

   
Net Asset Value and Pricing of Orders 
   Shares of each Fund are sold at the public offering price, which is the 
net asset value per share, plus the applicable sales charge. The net asset 
value per share is determined by dividing the value of the assets allocable 
to a Fund, less liabilities, by the number of shares outstanding. The net 
asset value is computed once daily, on each day the New York Stock Exchange 
(the "Exchange") is open, as of the close of regular trading hours of the 
Exchange. 
   An order for shares received by a broker-dealer prior to the close of 
regular trading of the Exchange (currently 4:00 p.m. Eastern Time) is 
confirmed at the offering price determined at the close of the Exchange on 
the day the order is received, provided the order is received by PFD prior to 
PFD's close of business (normally 5:30 p.m. Eastern Time). It is the 
responsibility of broker-dealers to transmit orders promptly so that they 
will be received by PFD prior to its close of business. An order received by 
a broker-dealer following the close of regular trading of the Exchange will 
be confirmed at the offering price as of the close of regular trading of the 
Exchange on the next trading day. 
   The Trust reserves the right in its sole discretion to withdraw all or any 
part of the offering of shares when, in the judgment of the Trust's 
management, such withdrawal is in the best interest of a 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. 
   Inasmuch as the market for municipal obligations is a dealer market with 
no central trading location or continuous quotation system, it is not 
feasible to obtain the last transaction prices for most municipal obligations 
in each of the Fund's portfolios, and such obligations, including those 
purchased on a when-issued basis, will normally be valued on the basis of 
valuations furnished by a pricing service. The pricing service uses 
information with respect to transactions in bonds, quotations from bond 
dealers, market transactions in comparable securities, various relationships 
between securities, and yield to maturity in determining value. Taxable 
obligations for which price quotations are readily available normally will be 
valued at the mean between the latest available bid and asked prices. Other 
assets are valued at fair value using methods determined in good faith by the 
Trustees. 
    

Dividends, Distributions and Taxation 
   Federal Taxation 
   Each Fund has elected to be treated, has qualified and intends to qualify 
each year as a separate "regulated investment company" under the Code so that 
it will not pay federal income taxes on income and capital gains distributed 
to shareholders at least annually. Because each of the Funds intends to 
distribute all or substantially all of its taxable (if any) and tax-exempt 
net investment income and net realized capital gains to shareholders in a 
timely manner, it is not expected that the Funds will be required to pay any 
federal income taxes. 
   The Code permits tax-exempt interest received by a Fund that qualifies as 
a regulated investment company to flow through as tax-exempt "exempt-interest 
dividends" to the Fund's shareholders, provided that at least 50% of the 
value of the total assets of the Fund at the close of each quarter of its 
taxable year consists of tax-exempt obligations. The Funds do not presently 
plan to invest in any "private activity bonds" subject to the federal 
alternative minimum tax for individuals. All tax exempt distributions may 
result in or increase a corporate shareholder's liability for the federal 
alternative minimum tax. 
   Interest on indebtedness incurred by a shareholder to purchase or carry 
shares of a Fund will not be deductible for federal income tax purposes to 
the extent the Fund's income dividends consist of exempt interest dividends. 
The Funds may not be an appropriate investment for persons who are 
"substantial users" of facilities financed by industrial revenue or private 
activity bonds or persons related to substantial users. Shareholders 
receiving social security or certain railroad retirement benefits may be 
subject to federal income tax on a portion of such benefits as a result of 
receiving investment income, including exempt-interest dividends and other 
distributions paid by the Funds. 
   Under the Code, a Fund will be subject to a non-deductible 4% federal 
excise tax on a portion of its undistributed ordinary income (if any) and net 
capital gains if it fails to meet certain distribution requirements with 
respect to each calendar year. Each Fund intends to make distributions in a 
timely manner and, accordingly, does not expect to be subject to the excise 
tax. 
   Each business day each Fund declares a dividend consisting of 
substantially all of its net investment income. Shareholders begin earning 
dividends on the first business day following receipt of payment for 
purchased shares. Shares continue to earn dividends up to and including the 
date of redemption. Dividends are normally paid on the last business day of 
the month or shortly thereafter. A Fund's net investment income consists of 
the interest income it earns, less expenses. In computing interest income, a 
Fund amortizes premium or accrues discount on long-term debt securities only 
to the extent required for federal income tax purposes. Distributions from 
net long-term and short term capital gains, if any, will be made at least 
annually. 
   While the Funds seek to maximize the percentage of income distributed 
which is not subject to federal income taxes, it is possible that under 
certain circumstances (see "Three Investment Programs") a small portion of 
the income dividends paid by the Funds will be subject to federal income tax. 
Dividends from a Fund's taxable net investment income, if any, recognized 
market discount income, and net short-term capital gains are taxable as 
ordinary income, and dividends from a Fund's net long-term capital gains are 
taxable as long-term capital gains. A portion of a Fund's distributions may 
also be subject to state and local income taxes (see "State Taxation," 
below). The federal income tax status of all distributions will be reported 
to shareholders annually, and shareholders are required to report all 
distributions, including tax-exempt distributions, on their federal income 
tax returns. 

                                      9 

<PAGE>
 
For federal income tax purposes, all dividends are treated as described above 
whether a shareholder takes them in cash or reinvests them in additional 
shares of a Fund. 
   Taxable dividends and other taxable distributions and the proceeds of 
redemptions (including exchanges) and repurchases of Fund shares paid to 
individuals and other non-exempt payees may be subject to 31% backup 
withholding of federal income tax if the Fund is not provided with the 
shareholder's correct taxpayer identification number and certification that 
the number is correct and 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 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 taxes. 

   State Taxation 
   Summaries of tax considerations for state income tax purposes for each of 
the Funds are set forth below. A more detailed discussion of state and local 
tax matters is included in the Statement of Additional Information. These 
discussions are only summaries of generally applicable state tax laws, and 
shareholders should consult their own tax advisers regarding the application 
of state, local and other applicable tax laws in their particular situations. 
   Pioneer California Double Tax-Free Fund. The Trust has obtained an opinion 
of Orrick, Herrington & Sutcliffe, special tax counsel to Pioneer California 
Double Tax-Free Fund, substantially to the effect that individual 
shareholders of Pioneer California Double Tax-Free Fund who are subject to 
California personal income taxation will not be required to include in their 
California gross income that portion of their federally tax-exempt dividends 
which the Fund clearly and properly identifies as excludable for California 
purposes, provided that at least 50 percent of the value of the Fund's total 
assets at the close of each quarter of the Fund's taxable year consists of 
obligations the interest on which is exempt from California personal income 
tax pursuant to federal or California law. Other distributions representing 
income or gains realized by the Fund will generally be subject to California 
personal income tax at the rates applicable to ordinary income. Corporate 
shareholders of the Fund which are subject to the California franchise tax 
generally will be required to include all distributions of exempt-interest 
dividends, capital gains and other taxable income, if any, as income subject 
to such tax. 
   Pioneer New York Triple Tax-Free Fund. The Trust has obtained an opinion 
of Orrick, Herrington & Sutcliffe, special tax counsel to Pioneer New York 
Triple Tax-Free Fund, substantially to the effect that individual 
shareholders of Pioneer New York Triple Tax-Free Fund who are subject to New 
York State or New York City personal income taxation will not be subject to 
New York State or City personal income taxes (including the minimum taxes 
contained therein) on distributions received from the Fund to the extent such 
distributions are exempt-interest dividends attributable to interest on tax- 
exempt obligations of the State of New York or a political subdivision 
thereof or derived from interest on obligations of possessions of the United 
States (including Puerto Rico, Guam and the U.S. Virgin Islands). Other 
distributions representing income or gains realized by the Fund will 
generally be subject to New York State or New York City personal income tax 
at the rates applicable to ordinary income. Corporate shareholders of the 
Fund that are subject to the New York State corporation franchise tax or the 
New York City general corporation tax generally will be required to include 
all distributions of exempt- interest dividends, capital gains and other 
taxable income, if any, as income subject to such taxes. 
   Pioneer Massachusetts Double Tax-Free Fund. The Trust has obtained an 
opinion of Hale and Dorr, counsel to the Trust, substantially to the effect 
that, provided that Pioneer Massachusetts Double Tax-Free Fund qualifies as a 
regulated investment company and complies with certain notice requirements, 
shareholders of Pioneer Massachusetts Double Tax-Free Fund that are 
individuals, estates or trusts and are subject to the Massachusetts income 
tax will be treated in the following manner for Massachusetts income tax 
purposes: Distributions that qualify as "exempt-interest dividends" under the 
Code and are attributable to interest received by the Fund on federally 
tax-exempt obligations issued by Massachusetts or a political subdivision 
thereof or a possession of the United States (including Puerto Rico, Guam and 
the U.S. Virgin Islands) and distributions of the Fund attributable to 
interest received by the Fund on direct obligations of the U.S. Government 
will not be subject to the Massachusetts income tax; distributions properly 
designated by the Fund as capital gain dividends under the Code and 
attributable to gain realized by the Fund on the sale of certain obligations 
issued pursuant to Massachusetts statutes that specifically exempt such gain 
from Massachusetts taxation will not be subject to the Massachusetts income 
tax; distributions properly designated by the Fund as capital gain dividends 
under the Code other than those described above will be treated as long-term 
capital gain for Massachusetts income tax purposes, regardless of the length 
of time Fund shares have been held; and distributions, other than those 
described above, that are included in federal gross income under the Code 
will be included in income subject to the Massachusetts income tax. 
Additionally, in determining the Massachusetts excise tax on shareholders 
that are corporations subject to Massachusetts taxation, distributions from 
the Fund that are included in federal gross income under the Code or that are 
excluded from federal gross income by virtue of Section 103(a) of the Code 
will be included in a corporate shareholder's net income, and in the case of 
intangible property corporations, shares of the Fund will be included in net 
worth. 
   Beginning in 1996, long-term capital gains will generally be taxed in 
Massachusetts on a sliding scale at rates ranging from 5% to 0%, with the 
applicable tax rate declining as the tax holding period of the asset 
(beginning on the later of January 1, 1995 or the date of actual acquisition) 
increases from more than one year to more than six years. It is not clear 
what Massachusetts tax rate will be applicable to capital gain dividends for 
taxable years beginning after 1995.

Redemptions and Repurchases 
   Redemption by Mail. As a shareholder, you have the right to offer your 
shares for redemption by delivering to PSC a written request for redemption, 
signed by all registered owners, in proper form and, if applicable, your 
share certificates properly endorsed and in good order for transfer. 
Redemptions will be made in cash at the net asset value per share next 
determined following receipt by PSC of all necessary documents subject in 
certain cases to the contingent deferred sales charge described below. 
   Good order means that there are no outstanding claims or requests to hold 
redemptions on the account, any certificates must be endorsed by the record 
owner(s) exactly as the shares are registered and the signature(s) must be 
guaranteed by any of the following eligible guarantor institutions: (i) all 
brokers, dealers, municipal securities dealers and/or brokers, who are 
members of a clearing agency or whose net capital exceeds $100,000; (ii) all 
banks; (iii) all credit unions; (iv) all savings associations, including all 
savings and loan associations; (v) all national securities exchanges, 
registered securities associations, and all clearing agencies; and (vi) all 
trust companies. In addition, in some cases (involving fiduciary or corporate 
transactions), good order may require the furnishing of additional documents. 
   Signature guarantees are not necessary for redemption requests of $50,000 
or less, provided that the request is in good order, the record holder 
executes the redemption request, payment is directed to the record holder at 
the record address, and the address was not changed during the previous 30 
days. You cannot provide a signature guarantee by facsimile ("fax"). Payment 
of redemptions normally will be made within seven days after receipt of the 
appropriate documents. The Trust reserves the right to withhold payment until 
checks received in payment of shares purchased have cleared, which may take 
up to 15 calendar days from the purchase date. For additional information 
about the necessary documentation for redemption by mail, please contact PSC 
at 1-(800)-225-6292. 
   Redemption by Telephone or Fax. Your account is automatically authorized 
to have the telephone redemption privilege unless you indicated otherwise on 
your Account Application or by writing to PSC. Proper account identification 
will be required for each telephone redemption. The telephone redemption 
option is not available to retirement plan accounts. A maximum of $50,000 may 
be redeemed by telephone or fax and the proceeds may be received by check or 
by bank wire 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 wire must be sent to the bank wire address of record which must 
have been properly pre- designated either on your Account Application or on 
an Account Options Form and which must not have changed in the last 30 days. 
To redeem by fax, send your redemption request to 1-800-225-4240. You may 
always elect to deliver redemption instructions to PSC by mail. See 
"Telephone Transactions and Related Liabilities" below. Telephone redemptions 
will be priced as described above. You are strongly urged to consult with 
your financial representative prior to requesting a telephone redemption. 
   Additional Conditions of Redemption. For the convenience of shareholders, 
the Trust has authorized PFD to act as its agent in the repurchase of shares 
of the Funds. Offers to sell shares to a Fund may be communicated to PFD by 
wire or telephone by broker-dealers for their customers. Each Fund 
repurchases shares offered to it at the net asset value per share determined 
as of the close of regular trading on the Exchange on the day the offer for 
repurchase is received in good order by the broker-dealer if the offer is 
received by PFD before the close of business on that day. 
   A broker-dealer which receives an offer for repurchase is responsible for 
the prompt transmittal of such offer to PFD. Payment of the repurchase 
proceeds will be made in cash to the broker-dealer placing the order. Except 
for certain large accounts subject to a CDSC (as described below) neither the 
Fund nor PFD charges any fee or commission upon such repurchase which is then 
settled as an ordinary transaction with the broker-dealer (which may charge 
the shareholder for this service) delivering the shares repurchased. Payment 
will be made within seven days after your order is received in good order by 
PSC of valid instructions, including validly endorsed certificates, if 
appropriate, in good order as described above. 
   The net asset value per share received upon redemption or repurchase may 
be more or less than the cost of shares to an investor, depending upon the 
market value of the portfolio at the time of redemption or repurchase. 
Redemptions and repurchases are taxable transactions. 
   Redemptions and repurchases 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 a Fund of securities owned by it is not 
reasonably practicable or it is not reasonably practicable for the Fund to 
fairly determine the value of the net assets of its portfolio; or the SEC, by 
order, so permits. 
   Purchases of $1,000,000 or more, and purchases by participants in a Group 
Plan which have not been subject to a sales charge, may be subject to a CDSC 
upon redemption or repurchase. A CDSC is payable to PFD on these investments 
in the event of a share redemption within twelve months following the share 
purchase, at the rate of 0.50% of the lesser of the value of the shares 
redeemed (exclusive of reinvested dividend and capital gain distributions) or 
the total cost of such shares. In determining whether a CDSC is payable, and, 
if so, the amount of the charge, it is assumed that shares purchased with 
reinvested dividend and capital gain distributions and then such other shares 
which are held the longest will be the first redeemed. Shares subject to the 
CDSC which are exchanged into another Pioneer mutual fund will continue to be 
subject to the CDSC until the original twelve-month period expires. 
   Waiver or Reduction of Contingent Deferred Sales Charge. The CDSC on any 
shares subject to a CDSC may be 
    


                                      11 

<PAGE>
 
   
waived or reduced for non-retirement accounts if: (a) the redemption results 
from the death of all registered owners of an account (in the case of UGMAs, 
UTMAs and trust accounts, waiver applies upon the death of all beneficial 
owners) or a total and permanent disability (as defined in Section 72 of the 
Code) of all registered owners occurring after the purchase of the shares 
being redeemed or (b) the redemption is made in connection with limited 
automatic redemptions as set forth in "Systematic Withdrawal Plans" (limited 
in any year to 10% of the value of the account in the Fund at the time the 
withdrawal plan is established). 
   The CDSC on any shares subject to a CDSC may be waived or reduced if: (a) 
the redemption is made by any state, county, or city, or any instrumentality, 
department, authority, or agency thereof, which is prohibited by applicable 
laws from paying a contingent deferred sales charge in connection with the 
acquisition of shares of any registered investment management company; or (b) 
the redemption is made pursuant to the Fund's right to liquidate or 
involuntarily redeem shares in a shareholder's account. 

Redemption of Small Accounts 
   If a shareholder holds shares of a Fund in an account with a net asset 
value of less than $500 due to redemptions or exchanges, the Fund may redeem 
the shares held in this account at net asset value if the shareholder has not 
increased the net asset value of the shares in the account to at least $500 
within six months of written notice by the Fund to the shareholder of the 
Fund's intention to redeem the shares. 

Description of Shares and Voting Rights 
   Under the Trust's Declaration of Trust, the Trustees are authorized to 
issue an unlimited number of shares of beneficial interest. The Trustees of 
the Trust are responsible for the overall management and supervision of its 
affairs. 
   The shares of the Trust are currently divided into three series. Each 
share represents an equal proportionate interest in a Fund with each other 
share. Generally, shares of each Fund will vote as a single series on 
matters, such as the election and removal of Trustees and the ratification of 
the selection of independent public accountants, that affect all Funds in 
substantially the same manner. As to matters affecting each Fund (e.g., 
changes in a Fund's investment restrictions or investment advisory 
agreement), shares of each Fund will vote as a separate series. Shares have 
no preemptive, subscription or conversion rights and are freely transferable. 
Shareholders are entitled to one vote for each share held and may vote in the 
election and removal of Trustees and on other matters submitted to 
shareholders. Each fractional share shall be entitled to a proportionate 
fractional vote. Shares are fully paid and, except as set forth in the 
Statement of Additional Information, non-assessable. 
   The Trust does not currently intend to hold annual meetings, although 
special meetings may be held for the purpose of voting on certain matters. 
The record holders of 10% of the Trust's outstanding shares may cause the 
Trust to call a special meeting of shareholders to consider the removal of 
one or more Trustees. As of December 29, 1995, PFD owned 34.05% of the 
outstanding shares of Pioneer New York Triple Tax-Free Fund and 47.92% of the 
outstanding shares of Pioneer Massachusetts Double Tax-Free Fund. See 
"Management of the Trust" in the Statement of Additional Information. The 
Trust reserves the right, without approval of shareholders, to create and 
issue additional series of shares in addition to the three Funds currently 
available. 
   Each Fund currently has only one class of shares, entitled Shares of 
Beneficial Interest. Shares of the Funds may also be divided into additional 
classes subject to such terms as the Trustees may establish without further 
shareholder action. 
   Under Massachusetts law, there is a remote possibility that shareholders 
of a business trust could, under certain circumstances, be held personally 
liable as partners for the obligations of such trust. The Declaration of 
Trust contains provisions intended to limit such liability and to provide 
indemnification out of Trust property of any shareholder charged or held 
personally liable for obligations or liabilities of the Trust solely by 
reason of being or having been a shareholder of a Fund and not because of 
such shareholder's acts or omissions or for some other reason. Thus, the risk 
of a shareholder incurring financial loss on account of shareholder liability 
is limited to circumstances in which the Trust itself would be unable to meet 
its obligations. 
   In the interest of economy and convenience, the Funds do not issue 
certificates representing Fund shares unless requested. Instead, the transfer 
agent maintains a record of each shareholder's ownership. Certificates for 
fractional shares will not be issued. Although there is currently no fee for 
the issuance of certificates, the Trust reserves the right to charge such a 
fee. 
    


VIII. SHAREHOLDER SERVICES 
   PSC is the shareholder services and transfer agent for shares of the 
Trust. PSC, a Massachusetts corporation, is a wholly owned subsidiary of PGI. 
PSC's offices are located at 60 State Street, Boston, Massachusetts 02109, 
and inquiries to PSC should be mailed to Pioneering Services Corporation, 
P.O. Box 9014, Boston, Massachusetts 02205-9014. Brown Brothers Harriman & 
Co. (the "Custodian") serves as the custodian of the Trust's portfolio 
securities and other assets. The principal business address of the Mutual 
Fund Division of the Custodian is 40 Water Street, Boston, Massachusetts 
02109. The fees of PSC and the Custodian are paid by each Fund. 
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 a Fund 
and might not be able to utilize some 



                                      12 

<PAGE>
 
   
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, 
systematic withdrawal plan, Letters of Intention, Rights of Accumulation, 
telephone purchases, exchanges and redemptions, and newsletters. 
    

Additional Investments 
   You may add to your account by sending a check ($50 minimum) to PSC; 
please indicate your account number clearly. The designated 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 applicable Fund at the applicable offering price in effect as of the 
close of the Exchange on the day of receipt. 

Automatic Investment Plans 
   You may arrange for regular automatic investments of $50 or more through 
payroll deduction, 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. Pioneer Investomatic Plan investments are 
voluntary, and you may discontinue the plan without penalty upon 30 days' 
written notice to PSC. PSC acts as agent for the purchasers, the 
broker-dealer and PFD in maintaining these plans. 

Financial Reports and Tax Information 
   Shareholders will receive financial reports at least semiannually. Annual 
reports will be audited by the Trust's independent public accountants. In 
January of each year, each Fund will mail to shareholders information about 
the tax status of dividends and distributions. 

Distribution Options 
   Dividends and capital gains distributions, if any, will automatically be 
invested in additional shares of each Fund in which you maintain an 
investment, 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 distributions 
in cash. These two options are not available, however, for 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 account. The 
value of this second account must be at least $1,000 ($500 for Pioneer Fund 
or Pioneer II). Invested dividends may be in any amount. There are no fees or 
charges for this service. 
    

   
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. 
    

   
Exchange Privilege 
   You may exchange your shares of any Fund in the Trust at net asset value, 
without a sales charge, for shares of other Pioneer mutual funds which do not 
offer different classes of shares or for the Class A shares of those Pioneer 
mutual funds that offer more than one class of shares. There are currently no 
sales charges or fees on exchanges. 
   Exchanges must be at least $1,000. In order to allow purchase transactions 
to clear you can not exchange shares purchased by check within 15 days. A new 
Pioneer mutual fund account opened through an exchange must have a 
registration identical to that on the original account. 
   PSC will process exchanges only after receiving an exchange request in 
proper form. The exchange privilege is available only in those states where 
the Pioneer mutual funds can be legally sold. 
     Written Exchanges. If the exchange request is in writing, it must be 
   signed by all record owner(s) exactly as the shares are registered. If 
   your original account includes an Investomatic or SWP and you open a new 
   account by exchange, you should specify whether the plans should continue 
   in your new account or remain with your original account. Written 
   exchanges may be sent by mail or fax. 
    

   
     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. Telephone exchanges may not exceed $500,000 per account 
   per day, and all telephone exchange requests will be recorded. Each 
   telephone exchange request, whether by voice or by FactFone(SM), will be 
   recorded. You are strongly urged to consult with your financial 
   representative prior to requesting a telephone exchange. See "Telephone 
   Transactions and Related Liabilities." 
    

   
   If an exchange request is received by PSC before 4:00 p.m. Eastern Time 
(or before the time that the New York Stock Exchange closes for regular 
trading on that day, if different), the exchange will be effective on that 
day if the requirements above have been met. If the exchange request is 
received after this time, the exchange will be effective on the following 
business day. 
   You should consider the differences in objectives and policies of the 
Pioneer mutual funds, as described in each fund's current prospectus, before 
making any exchange. For federal and (generally) state income tax purposes, 
an exchange represents a sale of the shares exchanged and a purchase of 
shares in another fund. Therefore, an exchange 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. For the protection of 
each Fund's performance and shareholders, the Funds and PFD reserve 
    

                                      13

the right to refuse any exchange request or restrict, at any time without 
notice, the number and/or frequency of exchanges to prevent abuses of the 
exchange privilege. Such abuses may arise from frequent trading in response 
to short- term market fluctuations, a pattern of trading by an individual or 
group that appears to be an attempt to "time the market," or any other 
exchange request which, in the view of management, will have a detrimental 
effect on the Fund's portfolio management strategy or operations. In 
addition, the Funds and PFD reserve the right to charge a fee for exchanges 
or to modify, limit, suspend or discontinue the exchange privilege with 
notice to shareholders as required by law. 
    

   
Telephone Transactions and Related Liabilities 
   Your account is automatically authorized to have telephone transaction 
privileges unless you indicated otherwise on your Account Application or by 
writing to PSC. You may purchase, sell or exchange Fund shares by telephone. 
See "Net Asset Value and Pricing of Orders" for more information. For 
personal assistance, call 1-800-225-6292 between 8:00 a.m. and 9:00 p.m. 
Eastern Time on weekdays. Computer- assisted transactions may be available to 
shareholders who have pre-recorded certain bank information (see 
"FactFone(SM)"). You are strongly urged to consult with your financial 
representative prior to requesting any telephone transaction. To confirm that 
each transaction instruction received by telephone is genuine, the Fund will 
record each telephone transaction, require the caller to provide the personal 
identification number ("PIN") for the account and send you a written 
confirmation of each telephone transaction. Different procedures may apply to 
accounts that are registered to non- U.S. citizens or that are held in the 
name of an institution or in the name of an investment broker-dealer or other 
third-party. If reasonable procedures, such as those described above, are not 
followed, the Fund may be liable for any loss due to unauthorized or 
fraudulent instructions. The Fund may implement other procedures from time to 
time. In all other cases, neither the Fund, PSC or PFD will be responsible 
for the authenticity of instructions received by telephone, therefore, you 
bear the risk of loss for unauthorized or fraudulent telephone transactions. 
   During times of economic turmoil or market volatility or as a result of 
severe weather or a natural disaster, it may be difficult to contact the Fund 
by telephone to institute a redemption or exchange. You should communicate 
with the Fund in writing if you are unable to reach the Fund by telephone. 
    

   
FactFone(SM) 
   FactFone(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 mutual fund accounts 
and to inquire about the price and yields of all publicly available Pioneer 
mutual funds. In addition, you may use FactFone(SM) to make computer-assisted 
telephone purchases, exchanges and redemptions from your Pioneer mutual fund 
accounts if you have activated your PIN. Telephone purchases and redemptions 
require the establishment of a bank account of record. You are strongly urged 
to consult with your financial representative prior to requesting any 
telephone transaction. Shareholders whose accounts are registered in the name 
of a broker-dealer or other third party may not be able to use FactFone(SM). 
See "How to Purchase Shares," "Exchange Privilege," "Redemptions and 
Repurchases" and "Telephone Transactions and Related Liabilities." Call PSC 
for assistance. 
   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. Periodic checks of $50 
or more will be sent to you monthly or quarterly, and your periodic 
redemptions of shares may be taxable transactions. You may also direct that 
withdrawal checks be paid to another person, although if you make this 
designation after you have opened your account, a signature guarantee must 
accompany your instructions. 
   Purchases of shares of a 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 
   If you redeem all or part of your shares of any Fund in the Trust, you may 
reinvest all or part of the redemption proceeds, subject to minimum 
investment requirements, without a sales commission in shares of the Fund or 
of any other Pioneer mutual 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. 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 Trust. 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. 
    

IX. INVESTMENT RESULTS 
   Each of the Funds may from time to time include yield information in 
advertisements or in information furnished generally to existing or proposed 
shareholders. Whenever yield information is provided, it includes a 
standardized yield calcu- 

                                      14 

<PAGE>
 
lation computed by dividing a Fund's net investment income per share during a 
base period of 30 days, or one month, by the maximum offering price per share 
of the Fund on the last day of such base period. (A Fund's net investment 
income per share is determined by dividing the Fund's net investment income 
during the base period by the average number of shares of the Fund entitled 
to receive dividends during the base period.) A Fund's 30-day yield is then 
"annualized" by a computation that assumes that the Fund's net investment 
income is earned and reinvested for a six-month period at the same rate as 
during the 30-day base period and that the resulting six-month income will be 
generated over an additional six months. 
   
   Each of the Funds may also from time to time advertise its taxable 
equivalent yield. A Fund's taxable equivalent yield is determined by dividing 
that portion of the Fund's yield (calculated as described above) that is tax 
exempt by one minus the combined federal, state and, if applicable, city tax 
rate, adjusted to take into account the deductibility of state and, if 
applicable, city taxes on an investor's federal income tax return, and adding 
the result to that portion, if any, of the Fund's yield that is not tax 
exempt. For a table of sample taxable equivalent yields for each Fund, please 
see the Appendix. 
    
   Each of the Funds may also include in advertisements and furnish to 
existing or prospective shareholders information concerning the average 
annual total return on an investment in the Fund for a designated period of 
time. Whenever this information is provided, it includes a standardized 
calculation of average annual total return computed by determining the 
average annual compounded rate of return that would cause a hypothetical 
investment (after deduction of the maximum sales charge) made on the first 
day of the designated period (assuming all dividends and distributions are 
reinvested) to equal the resulting net asset value of such hypothetical 
investment on the last day of the designated period. The periods illustrated 
would normally include one, five and ten years or such other periods as the 
Fund has been in existence. These standard calculations do not reflect the 
effect of federal or state taxes. 
   The computation methods above are prescribed for advertising and other 
communications subject to SEC Rule 482. Communications not subject to this 
rule may contain a number of different measures of performance, computation 
methods and assumptions, including but not limited to: historical total 
returns; distribution returns; results of actual or hypothetical investments; 
changes in dividends, distributions or share values; or any graphic 
illustration of such data. These data may cover any period of a Fund's 
existence and may or may not include the impact of sales charges, taxes or 
other factors. 
   Yield and average annual total return quotations of a Fund do not take 
into account any required payments for any federal or state income taxes. 
   Each 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. The temporary management fee reduction and expense 
limitation arrangement by PMC has the effect of increasing yield and total 
return. These factors and possible differences in the methods used in 
calculating investment results should be considered when comparing 
performance information regarding a Fund to information published for other 
investment companies and other investment vehicles. You should also consider 
yields and return quotations relative to changes in the value of a Fund's 
shares and the risks associated with a Fund's investment objectives and 
policies. Sinking fund call provisions and optional redemption features of 
portfolio securities may have the effect of reducing the stated average 
maturity of a Fund's portfolio, thereby reducing the Fund's yields. At any 
time in the future, yields and return quotations may be higher or lower than 
past yields or return quotations and there can be no assurance that any 
historical yield or return quotation will continue in the future. 
   The Funds may also include comparative performance information in 
advertising or marketing their shares. Such performance information may 
include rankings or listings by magazines, newspapers, or independent 
statistical or ratings services, such as Lipper Analytical Services, Inc. or 
Ibbotson Associates. 
   
   For more information about the calculation methods used to compute the 
Funds' investment results, see the Statement of Additional Information.

X. APPENDIX--Taxable Equivalent Yields 
    

   
                   PIONEER CALIFORNIA DOUBLE TAX-FREE FUND 
   The table below shows the effect of the tax status of bonds on the tax 
equivalent yield received by their holders under the regular federal and 
California State income tax rates for 1995 (State brackets are subject to 
inflation adjustment). It gives the approximate yield a taxable security must 
earn at various income brackets to produce after-tax yield equivalent to 
those of tax exempt bonds yielding from 5% to 9%. See "Investment Results," 
in the Prospectus for a discussion of how a Fund's taxable equivalent yield 
is calculated.

  * Net amount subject to federal and California personal income tax after 
    allowable deductions and exemptions. 

 ** The combined tax rates for the tax brackets shown in the left hand 
    columns are calculated using the highest California state rate applicable 
    at the upper portion of these brackets and assume that taxpayers deduct 
    California state income taxes paid on their federal income tax returns. 
    An investor with taxable income within these brackets may have a lower 
    combined tax rate than the combined rate shown and may, therefore, have a 
    lower tax equivalent yield than those indicated above. Investors who do 
    not itemize deductions on their federal income tax return may have a 
    higher combined bracket and a higher taxable equivalent yield than those 
    indicated above. Yields shown are for illustration purposes only and are 
    not meant to represent the Fund's actual yield. 
   
*** Effective January 1, 1996, the highest marginal California personal 
    income tax rate is reduced from 11% to 9.3%. This change in rate remains 
    subject to possible change by legislative action during 1996. Inflation 
    adjusted income brackets for California applicable to 1996 are not yet 
    available. 
    

   
   Note: The Federal Income Tax portion of above-indicated combined income 
tax brackets assumes that a single filer is not a "head of household," a 
"married individual filing a separate return" or a "surviving spouse" and 
does not take into account the effect of a reduction in the deductibility of 
Itemized Deductions (including California State Income Taxes) for taxpayers 
with Adjusted Gross Income in excess of $114,700 (or, in the case of a 
separate return by a married individual, $57,350). The tax brackets also do 
not show the effects of phaseout of personal exemptions for single filers 
with Adjusted Gross Income in excess of $114,700 and joint filers with 
Adjusted Gross Income in excess of $172,050. 
   Of course, no assurance can be given that Pioneer California Double 
Tax-Free Fund will achieve any specific tax exempt yield. While it is 
expected that the Fund will invest principally in obligations the interest 
from which is exempt from the regular federal income tax and California 
personal income taxes, other income received by the Fund may be taxable. The 
table does not take into account state or local taxes, if any, payable on 
Fund distributions except for California personal income taxes. It should 
also be noted that the interest earned on certain "private activity bonds" 
issued after August 7, 1986, while exempt from the regular federal income 
tax, is treated as a tax preference item which could subject a recipient to 
or increase his or her liability for federal alternative minimum tax. Since 
the Fund does not presently intend to invest in any bonds that will be 
subject to the federal alternative minimum tax, the illustrations assume that 
the federal alternative minimum tax is not applicable and do not take into 
account any tax credits that may be available.

   York City rate applicable at the upper portion of these brackets and

   their federal income tax returns. Therefore, an investor with taxable 
   income below the highest dollar amount in the lowest bracket may have a 
   lower combined tax rate than the combined rate shown for that bracket and 
   may, therefore, have a lower tax equivalent yield than those indicated 
   above. The applicable State and New York City rates are the maximum rate

- ----------
 * Net amount subject to federal and Massachusetts personal income tax after 
   allowable deductions and exemptions. 
** The combined tax rates include a Massachusetts tax rate of 12% applicable 
   to taxable bond interest and dividends, and assume that Massachusetts 
   taxes are itemized deductions for federal income tax purposes. Investors 
   who do not itemize deductions on their federal income tax return may have 
   a higher combined bracket and a higher taxable equivalent yield than those 
   indicated above. Yields shown are for illustration purposes only and are 
   not meant to represent the Fund's actual yield. 

   
   Note: The Federal Income Tax portion of above-indicated combined income 
tax brackets assumes that a single filer is not a "head of household", a 
"married individual filing a separate return" or a "surviving spouse" and 
does not take into account the effect of a reduction in the deductibility of 
Itemized Deductions (including Massachusetts State Income Taxes) for 
taxpayers with Adjusted Gross Income in excess of $117,950 (or, in the case 
of a separate return by a married individual, $58,975). The tax brackets also 
do not show the effects of phaseout of personal exemptions for single filers 
with Adjusted Gross Income in excess of $117,950 or, in the case of married 
persons filing jointly, $176,950. 
   Of course, no assurance can be given that Pioneer Massachusetts Double 
Tax-Free Fund will achieve any specific tax exempt yield. While it is 
expected that the Fund will invest principally in obligations the interest 
from which is exempt from the regular federal income tax and Massachusetts 
personal income taxes, other income received by the Fund may be taxable. The 
table does not take into account state or local taxes, if any, payable on 
Fund distributions except for Massachusetts personal income taxes. It should 
also be noted that the interest earned on certain "private activity bonds" 
issued after August 7, 1986, while exempt from the regular federal income 
tax, is treated as a tax preference item which could subject the recipient to 
or increase his liability under the federal alternative minimum tax. Since 
the Fund does not presently intend to invest in any bonds that will be 
subject to the federal alternative minimum tax, the illustrations do not 
include the effect of any federal alternative minimum tax. 
    

                                   ----------
    The information set forth above is as of the date of this Prospectus. 
Subsequent tax law changes could result in prospective or retroactive changes 
  in the tax brackets, tax rates and tax equivalent yields set forth above.

1.       INVESTMENT OBJECTIVES, POLICIES AND RESTRICTIONS

         Investment Objectives and Policies

   
         The  Prospectus of the Trust dated January 26, 1996 (the  "Prospectus")
identifies  the  investment  objectives  of each  series of the  Trust,  Pioneer
California  Double  Tax-Free  Fund,  Pioneer New York Triple  Tax-Free  Fund and
Pioneer   Massachusetts   Double   Tax-Free  Fund   (individually,   "Fund"  and
collectively,  the "Funds"), and the principal investment policies of the Funds.
Other investment  policies and a further  description of certain of the policies
described in the  Prospectus  are set forth below.  The  following  policies and
limitations  supplement  those discussed in the  Prospectus.  Appendices A and C
contain a further description of the municipal securities and other investments,
respectively,  which  comprise  the  Funds'  portfolios.  Appendix  B sets forth
ratings of  municipal  bonds by  Standard & Poor's  Ratings  Group  ("S&P")  and
Moody's Investors Service, Inc. ("Moody's").
    

         When-Issued Securities

         As  described in the  Prospectus  under the heading  "Three  Investment
Programs,"  the Funds may  purchase  new issues of  tax-exempt  securities  on a
"when-issued"  basis.  In order to invest the Funds' assets  immediately,  while
awaiting delivery of securities purchased on a "when-issued"  basis,  short-term
obligations  that  offer same day  settlement  and  earnings  will  normally  be
purchased.  Although  short-term  investments  will  normally  be in  tax-exempt
securities,   short-term   taxable  securities  may  be  purchased  if  suitable
short-term  tax-exempt  securities  are  not  available.  When a  commitment  to
purchase a security on a "when-issued" basis is made, procedures are established
consistent  with the General  Statement of Policy of the Securities and Exchange
Commission  concerning such purchases.  Because that policy currently recommends
that an amount of a Fund's  assets  equal to the amount of the  purchase be held
aside or segregated to be used to pay for the  commitment,  cash or high-quality
debt  securities  sufficient to cover any  commitments are always expected to be
available. Nonetheless, such purchases may involve more risk than other types of
purchases, as described in the Prospectus.

         Floating or Variable Rate Obligations

         Each Fund may purchase floating or variable rate obligations.  Floating
or variable rate  instruments  provide for  adjustments  in the interest rate at
specified intervals (weekly,  monthly,  semi-annually,  etc.). The revised rates
are usually set at the issuer's discretion,  in which case the investor normally
enjoys the right to "put" the  security  back to the  issuer or his agent.  Rate
revisions  may   alternatively  be  determined  by  formula  or  in  some  other
contractual fashion. Floating or variable rate obligations normally provide that
the holder can demand  payment  of the  obligation  on short  notice at par with
accrued interest and are frequently secured by letters of credit or other credit
support

                                      B-2
<PAGE>

arrangements  provided by banks. A Fund would anticipate using these obligations
as cash equivalents pending longer term investment of its funds.

         Redemption, Demand and Put Features

         Most municipal bonds have a fixed final maturity date.  However,  it is
commonplace for the issuer to reserve the right to call the bond earlier.  Also,
some bonds may have "put" or "demand"  features  that allow early  redemption by
the  bondholder.  Interest  income  generated  by certain  bonds having "put" or
"demand"  features  may not  qualify  as  tax-exempt  interest  if a Fund is not
treated as the tax owner of the bond. The Funds intend to take the position that
they own for tax  purposes  any  obligation  with  put or  demand  features  and
accordingly  may be  limited  in the  types of put or demand  features  they may
obtain.  Longer  term  fixed-rate  bonds may give the  holder a right to request
redemption at certain times (often  annually after the lapse of an  intermediate
term).  These  bonds  are  more  defensive  than  conventional  long-term  bonds
(protecting  to some degree  against a rise in interest  rates) while  providing
greater  opportunity than comparable  intermediate term bonds,  since a Fund may
retain  the  bond if  interest  rates  decline.  By  acquiring  these  kinds  of
obligations  a Fund obtains the  contractual  right to require the issuer of the
security or some other person to purchase the security at an agreed upon price.

         Concentration

         Each  Fund may  invest  25% or more of its total  assets  in  municipal
obligations  of the same  type,  including  without  limitation  the  following:
general  obligations  of its  respective  state and its political  subdivisions;
lease  rental  obligations  or  certificates  of state  and  local  authorities;
obligations of state and local housing finance authorities,  municipal utilities
systems or public housing  authorities;  or industrial  development or pollution
control bonds issued for hospitals,  electric utilities,  steel companies,  life
care  facilities  or other  purposes.  There  could  be  economic,  business  or
political   developments  which  might  affect  all  California,   New  York  or
Massachusetts obligations of a similar type.

         Each Fund's investment  objective and the investment policies described
above and the policies with respect to portfolio  management described below may
be changed without shareholder approval.

         Portfolio Management

         The Funds intend to manage their portfolios fully by buying and selling
securities,  as well as  holding  securities  to  maturity.  In  managing  their
portfolios  each Fund seeks to take advantage of market  developments  and yield
disparities, which may include use of the following strategies:

                                      B-3
<PAGE>

                  (1)  shortening  the  average  maturity  of its  portfolio  in
         anticipation of a rise in interest rates so as to minimize depreciation
         of principal;

                  (2)  lengthening  the  average  maturity of its  portfolio  in
         anticipation  of  a  decline  in  interest  rates  so  as  to  maximize
         tax-exempt yield;

                  (3) selling one type of debt security  (e.g.,  revenue  bonds)
         and buying another (e.g.,  general  obligation  bonds) when disparities
         arise in the relative values of each; and

                  (4) changing from one debt security to an essentially  similar
         debt security  when their  respective  yields  appear  distorted due to
         market factors.

         Each Fund engages in portfolio trading if it believes a transaction net
of costs  (including  custodian  charges) will help in achieving its  investment
objective.

         Investment Restrictions

         Each Fund has adopted certain additional investment  restrictions which
may not be changed without the affirmative  vote of the holders of a majority of
such Fund's outstanding voting securities.  Under these restrictions, a Fund may
not:

         (1) Issue senior securities, except as permitted by paragraphs (2), (6)
and (7) below.  For  purposes  of this  restriction,  the  issuance of shares of
beneficial  interest  in  multiple  classes or series,  the  purchase or sale of
options,   futures   contracts  and  options  on  futures   contracts,   forward
commitments,  and repurchase agreements entered into in accordance with a Fund's
investment policy, and the pledge,  mortgage or hypothecation of a Fund's assets
within  the  meaning  of  paragraph  (3)  below  are  not  deemed  to be  senior
securities.

         (2)  Borrow  money,  except  from  banks  as a  temporary  measure  for
extraordinary  emergency  purposes  in amounts not to exceed 33 1/3% of a Fund's
total assets (including the amount borrowed) taken at market value. No Fund will
use leverage to attempt to increase income. A Fund will not purchase  securities
while outstanding borrowings exceed 5% of a Fund's total assets.

         (3) Pledge,  mortgage,  or  hypothecate  its  assets,  except to secure
indebtedness  permitted by paragraph  (2) above and then only if such  pledging,
mortgaging  or  hypothecating  does not exceed 33 1/3% of a Fund's  total assets
taken at market value.

         (4) Act as an  underwriter,  except to the extent that,  in  connection
with the  disposition  of  portfolio  securities,  a Fund may be deemed to be an
underwriter for purposes of the Securities Act of 1933.


                                      B-4
<PAGE>

         (5) Purchase or sell real estate,  or any interest  therein,  including
real  estate  mortgage  loans,  except that a Fund may invest in  securities  of
corporate  or  governmental  entities  secured  by  real  estate  or  marketable
interests  therein or  securities  issued by  companies  (other than real estate
limited partnerships) that invest in real estate or interests therein.

         (6) Make loans,  except that a Fund may lend  portfolio  securities  in
accordance  with the  Fund's  investment  policies.  The Funds do not,  for this
purpose,  consider the purchase of repurchase  agreements,  bank certificates of
deposit,  a  portion  of an issue  of  publicly  distributed  bonds,  bank  loan
participation agreements, bankers' acceptances,  debentures or other securities,
whether  or  not  the  purchase  is  made  upon  the  original  issuance  of the
securities, to be the making of a loan.

         (7) Invest in commodities or commodity  contracts or in puts, calls, or
combinations  of both,  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
commitments,  securities  index put or call warrants and  repurchase  agreements
entered into in accordance with a Fund's investment policies.

         No Fund has any intention of investing its assets in the current fiscal
year in 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 commitments, or securities index put
or call warrants.

         In addition,  as a matter of  nonfundamental  investment  policy and in
connection  with the  offering  of its shares in various  states,  each Fund has
agreed not to:

         (a) Participate on a joint-and-several  basis in any securities trading
account.  The  "bunching"  of  orders  for the sale or  purchase  of  marketable
portfolio  securities with other accounts under the management of the Adviser to
save  commissions  or to average  prices among them is not deemed to result in a
securities trading account.

         (b) Purchase  securities on margin or make short sales unless by virtue
of its ownership of other securities,  a Fund has the right to obtain securities
equivalent  in kind and  amount  to the  securities  sold  and,  if the right is
conditional,  the sale is made upon the same conditions,  except that a Fund may
obtain  such  short-term  credits  as may be  necessary  for  the  clearance  of
purchases and sales of securities.


                                      B-5
<PAGE>

         (c) Purchase a security if, as a result,  (i) more than 10% of a Fund's
assets would be invested in securities of closed-end investment companies,  (ii)
such  purchase  would  result in more than 3% of the  total  outstanding  voting
securities of any one such closed-end  investment  company being held by a Fund,
or (iii)  more  than 5% of a Fund's  assets  would be  invested  in any one such
closed-end  investment  company.  No Fund will invest in the  securities  of any
open-end investment company.

         (d)  Purchase  securities  of  any  issuer  which,  together  with  any
predecessor,  has a record of less than three years' continuous operations prior
to the purchase if such purchase  would cause  investments of a Fund in all such
issuers to exceed 5% of the value of the total assets of the Fund.

         (e) Invest for the purpose of exercising  control over or management of
any company.

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

         (g) Knowingly purchase or retain securities of an issuer if one or more
of the Trustees or officers of the Trust or directors or officers of the Adviser
or any  investment  management  subsidiary  of  the  Adviser  individually  owns
beneficially  more than 0.5% and together own  beneficially  more than 5% of the
securities of such issuer.

         (h)  Purchase  interests  in  oil,  gas or  other  mineral  exploration
programs;  however,  this policy will not prohibit the acquisition of securities
of companies  engaged in the  production  or  transmission  of oil, gas or other
minerals.

         (i) Purchase any security,  including any repurchase agreement maturing
in more than seven days,  which is illiquid,  if more than 15% of the net assets
of a Fund, taken at market value,  would be invested in such  securities.  These
restrictions may not be changed without the approval of the regulatory  agencies
in such states.

         For the purposes of the Fund's investment restrictions, the issuer of a
tax-exempt  security is deemed to be the entity  (public or private)  ultimately
responsible for the payment of the principal of, and interest on, the security.


                                      B-6
<PAGE>

         Percentage Restrictions

         If a percentage  restriction on investment or utilization of assets set
forth above (other than with respect to  borrowing) is adhered to at the time an
investment  is made or assets  are so  utilized,  a later  change in  percentage
resulting from changes in the value of a Fund's portfolio securities will not be
considered a violation of a policy.
       

2.       MANAGEMENT OF THE TRUST

         The  Trust's  Board of Trustees  provides  broad  supervision  over the
affairs of the Trust.  The officers of the Trust are responsible for the Trust's

To the  knowledge  of the Trust,  no officer or Trustee of the Trust owned 5% or
more of the issued and  outstanding  shares of PGI on December 31, 1995,  except
Mr. Cogan who then owned approximately 15% of such shares. At December 31, 1995,
the Trustees and officers of the Funds owned, in the aggregate,  less than 1% of
the outstanding shares of each of the Funds. At December 31, 1995, the following
persons  owned 5% or more of the  outstanding  shares of the Funds:  (i) Pioneer
California   Double   Tax-Free   Fund,   PIC,  60  State  Street,   Boston,   MA
02109-1803--7.93%;  Wallace  Linville  Trust,  28766 Glen Oaks Drive,  Sun City,
California  92586-2843--16.76%;  and Merrill  Lynch Pierce  Fenner & Smith Inc.,
4800 Deer Lake Drive East 3rd F1, Jacksonville, Florida 32246-6484--5.71%;  (ii)
New  York  Triple   Tax-Free   Fund,   PFD,   60  State   Street,   Boston,   MA
02109-1803--34.05%;  and (iii) Massachusetts Double Tax-Free Fund, PFD, 60 State
Street,  Boston,  MA  02109-1803--47.92%  and Arthur  David Rev Trust,  14 First
Street,  Salisbury,  MA  01952-2515--9.88%.  PFD and PIC are organized under the
laws of  Massachusetts  and are deemed to be controlling  persons of any Fund of
which they own more than 25% of the shares outstanding. As such, the exercise by
PFD or PIC of  their  voting  rights  may  diminish  the  voting  power of other
shareholders.

         Compensation  of Officers and  Trustees.  The Trust pays no salaries or
compensation to any of its officers.  Commencing on October 1, 1996, each series
of the  Trust  will  pay an  annual  trustees'  fee to each  Trustee  who is not
affiliated with PMC, PFD or PSC consisting of two components:  (a) a base fee of
$500 and (b) a variable  fee,  calculated on the basis of the average net assets
of each series,  estimated to be  approximately  $5 for 1996. In addition,  each
series of the Trust will pay a per  meeting  fee of $120 to each  Trustee who is
not affiliated with PMC, PFD or PSC. The Trust also will pay an annual committee
participation fee to Trustees who serve as members of committees  established to
act on behalf of one or more of the Pioneer mutual funds. Committee fees will be
allocated  to the Trust on the basis of the Trust's  average  net  assets.  Each
Trustee who is a member of the Audit Committee for the Pioneer mutual funds will
receive an annual fee equal to 10% of the aggregate annual trustees' fee, except
the Committee Chair who will receive an annual trustees' fee equal to 20% of the
aggregate annual trustees' fee. The Audit Committee fees for each member and the
Committee  Chair for 1996 are expected to be  approximately  $6,000 and $12,000,
respectively.  Members of the Pricing Committee for the Pioneer mutual funds, as
well as any other committee which renders  material  functional  services to the
Board of Trustees for the Pioneer mutual funds, will receive an annual fee equal
to 5% of the annual  trustees' fee,  except the Committee Chair who will receive
an annual  trustees' fee equal to 10% of the annual  trustees'  fee. The Pricing
Committee fees for each member and the Committee  Chair for 1996 are expected to
be  approximately  $3,000  and  $6,000,  respectively.  Any  such  fees  paid to
affiliates or interested  persons of PMC, PFD or PSC are reimbursed to the Trust
under its Management Contract.

         For the fiscal year ended  September 30, 1995, the Trust paid an annual
trustees'  fee of $500 to each Trustee who was not  affiliated  with PMC, PFD or
PSC as well as an annual fee of $200 to each of the Trustees who was a member of
the Trust's  Audit  Committee,  except for the Chairman of such  Committee,  who
received an annual fee of $250.  The Trust also paid 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
were reimbursed to the Trust under its Management Contract.

     such date there were 33 separate series in the Pioneer Family of Funds.
    

         Unless  otherwise  required by the 1940 Act,  ordinarily it will not be
necessary for the Trust to hold annual  meetings of  shareholders.  As a result,
shareholders  may not consider the  election of Trustees or the  appointment  of
independent  accountants  each  year.  Shareholders  may remove a Trustee by the
affirmative  vote of at least two-thirds of the Trust's  outstanding  shares and
the Trustees must promptly call a meeting for such purpose when  requested to do
so in  writing by the  record  holders  of not less than 10% of the  outstanding
shares of the Trust. Shareholders may, under certain circumstances,  communicate
with other  shareholders


                                      B-12
<PAGE>

in connection with requesting a special  meeting of  shareholders.  The Board of
Trustees,  however,  will call a special  meeting  for the  purpose of  electing
Trustees if, at any time, less than a majority of Trustees holding office at the
time were elected by shareholders.

3.       INVESTMENT ADVISER

         The  Trust  has   contracted   with  PMC,  60  State  Street,   Boston,
Massachusetts,  to act as its  investment  adviser.  The term of the  Management
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 Trust (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
a majority of its  outstanding  voting  securities and the giving of sixty days'
written notice.

   
         As compensation for its management services and expenses incurred,  PMC
is  entitled  to a  management  fee at the rate of 0.60% per annum of the Funds'
average daily net assets.  The fee is normally  computed daily and paid monthly.
PMC has  voluntarily  agreed not to impose any of its management fee and to make
other arrangements,  if necessary,  to limit certain other expenses of the Trust
to the extent  required  to limit each Fund's  total  expenses to the levels set
forth in the Funds'  prospectus under "Expense  Information".  This agreement is
voluntary and temporary and may be revised or terminated at any time.
    

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

   
         During the fiscal years ended  September 30, 1995,  September 30, 1994,
and the fiscal  period from  February 19, 1993 (date of  inception) to September
30, 1993, PMC did not receive any  compensation  from the Funds because of PMC's
voluntary agreement to limit each Fund's expenses. Absent such an agreement, PMC
would have received for the periods noted management fees as follows: California
Double  Tax-Free  Fund,  $40,877,  $33,251  and  $10,800;  Massachusetts  Double
Tax-Free Fund,  $24,024,  $21,874 and $8,685; and New York Triple Tax-Free Fund,
$28,039, $22,193 and $8,364.

4.       UNDERWRITING AGREEMENT AND DISTRIBUTION PLAN

         The  Trust  is a party  to an  Underwriting  Agreement  with  PFD.  See
"Principal  Underwriter"  below.  The  Trustees who are not, and were not at the
time they voted,  interested  persons of the Trust,  as defined in the 1940 Act,
approved the Underwriting  Agreement.  The Underwriting  Agreement will continue
from year to year if annually  approved by the Trustees in conjunction  with the
continuance of the Rule 12b-1 distribution plan (the  "Distribution  Plan"). The
Underwriting Agreement provides that PFD will bear expenses for the distribution
of the Funds'  shares,  except for the expenses  incurred by PFD for which it is
reimbursed by the Funds under the Distribution Plan.

   
         PFD  bears all  expenses  it incurs  in  providing  services  under the
Underwriting Agreement.  Such expenses include compensation to its employees and
representatives  and to securities  dealers for  distribution  related  services
performed for the Funds.  PFD also pays certain  expenses in connection with the
distribution of the Funds' 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. Each Fund
bears the cost of registering its shares under federal and state securities law.
The  Trust  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 Trust.  During the fiscal year ending  September  30, 1995,  net
underwriting  commissions  retained by PFD and commissions  reallowed to dealers
were approximately:
    

                                                  Retained            Reallowed

   
Pioneer California Double Tax-Free Fund           $5,877               $28,955
Pioneer New York Triple Tax-Free Fund             $2,926               $15,727
Pioneer Massachusetts Double Tax-Free Fund        $2,289               $11,639
    

         The Trust has  adopted  a  Distribution  Plan  pursuant  to Rule  12b-1
promulgated  by the  Securities  and  Exchange  Commission  under  the  1940 Act
pursuant to which a Fund may reimburse PFD for its expenditures in financing any
activity  primarily  intended  to  result  in the sale of Fund  shares.  Certain
categories of such  expenditures have been approved by the Board of Trustees and
are set forth in the  Prospectus  under the  caption  "Distribution  Plan."  The
expenses of each Fund pursuant to the Distribution  Plan are accrued on a fiscal
year basis and may not exceed the annual  rate of .25 of 1% of a Fund's  average
annual net assets.  The Distribution  Plan does not provide for the carryover of
reimbursable  expenses beyond twelve months from the time they are incurred.  In
accordance  with the terms of the  Distribution  Plan,  the manager of the Trust
provides to the Trust for review by the Trustees a quarterly  


                                      B-14
<PAGE>

written  report of the  amounts  expended  under the  Distribution  Plan and the
purpose  for which such  expenditures  were  made.  PFD has agreed to act as the
servicing agent of the Trust with respect to the Distribution Plan.

         No interested  person of the Trust, nor any Trustee of the Trust who is
not an  interested  person of the Trust,  has any direct or  indirect  financial
interest in the operation of the Distribution Plan 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  Distribution  Plan by
each of the Funds and except to the extent certain officers may have an interest
in PFD's ultimate parent, PGI.

   
         The  Distribution  Plan was 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 Trust, as defined in the 1940 Act (none of
whom had or have any direct or indirect  financial  interest in the operation of
the  Distribution  Plan),  cast in person at a meeting called for the purpose of
voting  on the  Distribution  Plan and  approved  by the  Trust's  sole  initial
shareholder.  In approving the  Distribution  Plan, the Trustees  identified and
considered  a number  of  potential  benefits  which the  Distribution  Plan may
provide.  The Board of Trustees  believes that there is a reasonable  likelihood
that the  Distribution  Plan will benefit each Fund and their current and future
shareholders. Under its terms, the Distribution Plan remains in effect from year
to year provided such  continuance is approved  annually by vote of the Trustees
in the  manner  described  above.  The  Distribution  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  affected   thereby,   and  any  amendments  to  the
Distribution  Plan must also be approved by the Trustees in the manner described
above. The Distribution  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 Trust and that have no direct or indirect  financial  interest in
the  operations  of the  Distribution  Plan,  or by a vote of a majority  of the
outstanding  voting  securities  of the Trust (as defined in the 1940 Act).  The
Distribution  Plan will  automatically  terminate in the event of its assignment
(as  defined  in  the  1940  Act).  In the  Trustees'  quarterly  review  of the
Distribution  Plan,  they will  consider its continued  appropriateness  and the
level of  compensation  it  provides.  During the period from October 1, 1994 to
September  30,  1995,  the  Funds  paid  distribution  fees  to PFD as  follows:
California Double Tax-Free Fund, $10,141; New York Triple Tax-Free Fund, $1,234;
and Massachusetts  Double Tax-Free Fund, $1,082.  Distribution fees were paid in
reimbursement  of expenses  related to servicing of shareholder  accounts and to
compensating dealers and sales personnel.

5.       SHAREHOLDER SERVICING/TRANSFER AGENT

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

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

   
         PSC receives an annual fee of $30.00 per  shareholder  account from the
Trust as compensation for the services  described  above.  This fee is set at an
amount  determined by vote of a majority of the Trustees of the Trust (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., 40 Water Street,  Boston,  Massachusetts
02109, (the "Custodian") is the custodian of the Trust's assets. The Custodian's
responsibilities  include  safekeeping  and  controlling  each  Fund's  cash and
securities,  handling the receipt and  delivery of  securities,  and  collecting
interest  and  dividends  on the  Funds'  investments.  The  Custodian  does not
determine the  investment  policies of the Funds or decide which  securities the
Funds will buy or sell. The Funds 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,  serves as the principal
underwriter  for the Trust in  connection  with the  continuous  offering of its
shares.

8.       INDEPENDENT PUBLIC ACCOUNTANT

         Arthur Andersen LLP, One  International  Place,  Boston,  Massachusetts
02110 is the Trust's  independent public  accountant,  providing audit services,
tax  return  review,  and  assistance  and  consultation  with  respect  to  the
preparation of filings with the Securities and Exchange Commission.

9.       PORTFOLIO TRANSACTIONS

         Decisions  relating  to the  purchase  and sale of  securities  for the
Funds,  the  allocation of portfolio  transactions  and, where  applicable,  the
negotiation of commission rates are made by officers of PMC.

         The primary consideration in placing portfolio security transactions is
execution  at the most  favorable  prices.  PMC has  complete  freedom as to the
markets in and  broker-dealers  through  which it seeks this  result.  Municipal
Obligations   and  other  debt   securities   are  traded   principally  in  the
over-the-counter  market on a net basis  through  dealers  acting  for their own
account and not as brokers.  The cost of securities  purchased from underwriters
includes an  underwriter's  commission  or  concession,  and the prices at which
securities are purchased and sold from and to dealers include a dealer's mark-up
or  mark-down.  PMC  attempts to  negotiate  with  underwriters  to decrease the
commission or  concession  for the benefit of the Funds.  PMC normally  seeks to
deal directly  with the primary  market makers  unless,  in its opinion,  better
prices are available elsewhere.

         Subject to the  requirement of seeking  execution at the best available
price,  securities may, as authorized by PMC's management  agreement,  be bought
from or sold to dealers who furnish research  services to the Funds and/or other
investment companies managed by PMC, or who sell shares of the Funds.  Brokerage
and research 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;  and  furnishing
analyses, manuals and reports concerning issuers,  securities,  economic factors
and trends,  portfolio  strategy,  performance  of  accounts,  comparative  fund
statistics  and credit rating  service  information.  PMC maintains a listing of
dealers who provide such services on a regular basis.  Management  believes that
no exact dollar value can be calculated for such services.

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

10.      TAX STATUS

   
         Each  Fund is  treated  as a  separate  entity  for tax and  accounting
purposes.  It is each 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,  diversification  of  its  assets  and  distribution  of its  income  to
shareholders.  If a 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 
    


                                      B-17
<PAGE>

of the  necessity  of paying  federal  income tax.  The Funds are not liable for
Massachusetts  corporate  excise or franchise  taxes and,  provided  that a Fund
qualifies as a regulated investment company for federal income tax purposes, the
Fund will also not be required to pay any Massachusetts income tax.

         In accordance  with its  investment  objectives,  each Fund invests its
assets in a manner which will provide as large a portion of tax-exempt income as
is consistent with the protection of shareholders' capital. Since the protection
of capital is an important  aspect of each Fund's  investment  objectives,  each
Fund may from  time to time  invest a portion  of its  portfolio  in  short-term
obligations  and may acquire  obligations or engage in  transactions  generating
income which is not tax-exempt,  e.g., purchase securities at a market discount,
purchase   non-municipal   securities,   purchase  certain  stripped  tax-exempt
obligations or their  coupons,  sell or lend  portfolio  securities,  enter into
repurchase  agreements,  or dispose of rights to when-issued securities prior to
issuance.

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

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

                                      B-18
<PAGE>

   
         Redemptions,  including  exchanges,  are taxable  transactions.  If the
shares  redeemed (or surrendered in an exchange) have been held for less than 91
days, the sales charge paid on the acquisition of such shares is not included in
their  federal  tax  basis for the  purposes  of  determining  gain or loss if a
reinvestment  in the Fund or exchange  into a different  Fund occurs,  in either
case to the extent a sales charge that would  otherwise  apply to acquisition of
the newly-acquired  shares is reduced or eliminated pursuant to the reinvestment
or exchange privilege.  Instead,  the portion of the sales charge so disregarded
is carried  over and  included in the  federal  tax basis of the  newly-acquired
shares. In addition, if a redemption results in a loss and an investment is made
in the same Fund within a period of 61 days  beginning 30 days before and ending
30 days after the redemption  (including by the reinvestment of  distributions),
the loss may be disallowed for federal income tax purposes under the "wash sale"
rules.  In such a case, the  disallowed  amount would be included in the federal
tax basis of the newly-acquired shares.

         Any loss on the sale or exchange of shares on which an  exempt-interest
dividend was paid that have a tax holding  period,  at the time of sale,  of six
months or less, is disallowed to the extent of the amount of such dividend.  Any
loss  realized and not  disallowed  on the sale or exchange 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  distributions  of long-term  capital gains with respect to
such shares.

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

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

         For  Federal  income  tax  purposes,  each Fund is  permitted  to carry
forward a net  capital  loss in any year to offset its  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.  As of September  30, 1995,  the Funds had the  following net loss
carryforwards:  Pioneer  California Double 
    


                                      B-19

Tax-Free Fund,  $109,121,  which will expire between 2002 and 2003;  Pioneer New
York Triple Tax-Free Fund, $61,226, which will expire between 2002 and 2003; and
Pioneer  Massachusetts Double Tax-Free Fund, $55,763,  which will expire between
2002 and 2003.

         Federal law requires that the Funds withhold (as "backup  withholding")
31% of reportable  payments,  including taxable income  dividends,  capital gain
dividends  and  the  proceeds  of  redemptions,  repurchases  or  exchanges,  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.
A 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.  Backup  withholding  may be  inapplicable  for any year in which a Fund
reasonably  estimates  that at least 95% of its  dividends  paid with respect to
such year are exempt-interest dividends.
    

         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. The description does not address special tax
rules  applicable to certain classes of investors,  such as insurance  companies
and financial institutions.

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

         The  exemption  of  exempt-interest  dividends  for federal  income tax
purposes  does not  necessarily  result in  exemption  under the tax laws of any
state or local taxing authority, which vary with respect to the taxation of such
dividend  income.  Some  states  will  exempt  from  tax  that  portion  of  the
exempt-interest  dividend which represents  interest  received by a Fund on that
state's securities, as described below with respect to California,  New York and
Massachusetts.

         California  State and  Local  Tax  Matters.  The  following  discussion
assumes  that Pioneer  California  Double  Tax-Free  Fund will be qualified as a
regulated  investment  company  under  subchapter  M of the  Code  and  will  be
qualified thereunder to pay exempt-interest dividends.

         In the opinion of Orrick,  Herrington & Sutcliffe,  special  California
tax counsel for Pioneer California Double Tax-Free Fund,  provided that the Fund
meets the 50% test described in the  prospectus,  shareholders  of the Fund that
are individuals, estates or trusts and are subject to California personal income
taxation will not be required to include in their  California  gross income that
portion of their  dividends  which the Fund clearly and properly  identifies  as
directly  attributable to interest earned on obligations,  the interest on which
is exempt from California personal income tax.

         Distributions to individual shareholders derived from interest on state
or municipal obligations issued by governmental authorities in states other than
California,  short-term  capital gains and other taxable income will be taxed as
dividends  for  purposes of  California  personal  income  taxation.  The Fund's
long-term  capital  gains  for  federal  income  tax  purposes  will be taxed as
long-term  capital  gains  to  shareholders  of the Fund  that are  individuals,
estates or trusts for purposes of California  personal income taxation.  Gain or
loss,  if any,  resulting  from an  exchange  or  redemption  of shares  will be
recognized in the year of the exchange or  redemption.  Present  California  law
taxes both  long-term and  short-term  capital gains at the rates  applicable to
ordinary income. Interest on indebtedness incurred or continued by a shareholder
in connection  with the purchase of shares of a Fund will not be deductible  for
California  personal income tax purposes.  California has an alternative minimum
tax similar to the federal alternative minimum tax described above. However, the
California  alternative  minimum  tax does not  include  interest  from  private
activity bonds as an item of tax preference.

         Generally, corporate shareholders of the Fund subject to the California
franchise  tax will be required to include any gain on an exchange or redemption
of shares and all  distributions  of exempt  interest,  capital  gains and other
taxable income, if any, as income subject to such tax.

         The Fund will not be  subject  to  California  franchise  or  corporate
income  tax  on  interest  income  or  net  capital  gain   distributed  to  the
shareholders.

         Shares  of the  Fund  will be  exempt  from  local  property  taxes  in
California.

         The  foregoing  is a  general,  abbreviated  summary  of certain of the
provisions of the California Revenue and Taxation Code presently in effect as it
directly  governs the taxation of shareholders of the Fund. These provisions are
subject to change by legislative or administrative  action,  and any such change
may be retroactive with respect to Fund  transactions.  Shareholders are advised
to consult with their own tax advisers for more detailed information  concerning
California tax matters.

         New York State and Local Tax Matters.  The following discussion assumes
that  Pioneer New York Triple  Tax-Free  Fund will be  qualified  as a regulated
investment  company  under  subchapter  M of the  Code  and  will  be  qualified
thereunder to pay exempt-interest dividends.

   
         In the opinion of Orrick, Herrington & Sutcliffe,  special New York tax
counsel for Pioneer New York Triple Tax-Free Fund, shareholders of the Fund that
are  individuals,  estates or trusts taxable under  subchapter J of the Code and
that are subject to New York State or New York City taxation will not be subject
to New York State or City  personal  income taxes  (including  the minimum taxes
contained  therein) on  distributions  received from the Fund to the extent such
distributions  are  exempt-interest   dividends   attributable  to  interest  on
tax-exempt  obligations  of the  State  of New York or a  political  subdivision
thereof or derived from interest on  obligations  of  possessions  of the United
States  (including  Puerto  Rico,  Guam  and  the  U.S.  Virgin  Islands).  Such
shareholders  will be able to treat  dividends  from the Fund which are "capital
gain  dividends"  as long-term  capital  gains for purposes of New York State or
City  personal  income  taxes.  Gain or  loss,  if any,  resulting  from a sale,
exchange or  redemption  of shares will be  recognized  in the year of the sale,
exchange  or  redemption.  New York  State and City  personal  income  taxes are
currently  imposed on both  long-term and  short-term  capital gains at the same
rates  that  apply to  ordinary  income.  Dividends  which  are not  treated  as
exempt-interest  dividends or as capital gain  dividends for purposes of the New
York State or City personal income taxes will be taxable to such shareholders as
ordinary  income  and will be  includable  in the  income  of such  shareholders
subject to New York State or City minimum taxes.

         Interest on  indebtedness  incurred or  continued  by  shareholders  to
purchase or carry shares of the Fund will not be  deductible  for New York State
or City personal income tax purposes.
    

         Shareholders  of the  Fund  that  are  subject  to the New  York  State
corporation  franchise tax or the New York City general  corporation tax will be
required to include exempt-interest  dividends paid by the Fund in their "entire
net  income" for  purposes  of such taxes and will be required to include  their
shares of the Fund in their investment capital for purposes of such taxes.

         Interest income or net capital gain of the Fund which is distributed to
the  shareholders  will generally not be taxable to the Fund for purposes of the
New  York  State  corporation  franchise  tax  or  the  New  York  City  general
corporation tax.

         The  foregoing  is a  general,  abbreviated  summary  of certain of the
provisions  of the New York  State  Tax Law and the tax  laws of New  York  City
presently in effect as they directly  govern the taxation of shareholders of the
Fund.  These  provisions are subject to change by legislative or  administrative
action,   and  any  


                                      B-22

such change may be retroactive with respect to Fund  transactions.  Shareholders
are advised to consult with their own tax advisers for more detailed information
concerning New York State and New York City tax matters.

         Massachusetts  State and Local Tax Matters.  The  following  discussion
assumes that Pioneer  Massachusetts  Double Tax-Free Fund will be qualified as a
regulated  investment  company  under  subchapter  M of the  Code  and  will  be
qualified thereunder to pay exempt-interest dividends.

         In the  opinion  of Hale and Dorr,  counsel  to  Pioneer  Massachusetts
Double  Tax-Free  Fund,   under   Massachusetts   law,   provided  that  Pioneer
Massachusetts  Double  Tax-Free Fund complies with certain notice  requirements,
shareholders of Pioneer Massachusetts Double Tax-Free Fund that are individuals,
estates  or trusts  and are  subject  to the  Massachusetts  income  tax will be
treated  in  the  following  manner  for  Massachusetts   income  tax  purposes:
Distributions that qualify as "exempt-interest dividends" under the Code and are
attributable  to  interest   received  by  the  Fund  on  federally   tax-exempt
obligations  issued by  Massachusetts  or a political  subdivision  thereof or a
possession of the United States (including Puerto Rico, Guam and the U.S. Virgin
Islands) and  distributions of the Fund attributable to interest received by the
Fund on direct  obligations  of the U.S.  Government  will not be subject to the
Massachusetts  income  tax;  distributions  properly  designated  by the Fund as
capital gain dividends  under the Code and  attributable to gain realized by the
Fund  on the  sale of  certain  obligations  issued  pursuant  to  Massachusetts
statutes that specifically exempt such gain from Massachusetts taxation will not
be subject to the Massachusetts income tax; distributions properly designated by
the Fund as capital  gain  dividends  under the Code other than those  described
above will be treated as  long-term  capital gain for  Massachusetts  income tax
purposes,  regardless  of the length of time Fund  shares  have been  held;  and
distributions,  other than those described  above,  that are included in federal
gross  income  under  the  Code  will  be  included  in  income  subject  to the
Massachusetts income tax. Additionally,  in determining the Massachusetts excise
tax on shareholders  that are corporations  subject to  Massachusetts  taxation,
distributions  from the Fund that are included in federal gross income under the
Code or that are excluded from federal gross income by virtue of Section  103(a)
of the Code will be included in a corporate shareholder's net income, and in the
case of intangible property corporations, shares of the Fund will be included in
net worth.

   
         Massachusetts  legislation  enacted  on  December  9, 1994 (the  "Act")
substantially  changed the  Massachusetts  income tax treatment of capital gains
realized by persons  subject to  Massachusetts  income  taxation,  effective for
taxable years  beginning on or after January 1, 1996.  Under the Act,  long-term
capital gains from the sale of a capital asset are generally  taxed on a sliding
scale at rates ranging from 5% to 0%, with the  applicable tax rate declining as
the tax holding  period of the asset  (beginning on the 
    


                                      B-23
<PAGE>

   
later of January 1, 1995 or the date of actual acquisition)  increases from more
than one year to more than six years.  Massachusetts  resident  individuals,  as
well as estates or personal trusts subject to Massachusetts income taxation, are
subject to this new tax  structure  with  respect to  redemptions,  exchanges or
other dispositions of their shares of Pioneer Massachusetts Double Tax-Free Fund
in their  taxable  years  beginning  after 1995,  assuming  that they hold their
shares of Pioneer  Massachusetts  Double  Tax-Free  Fund as  capital  assets for
purposes of the Act. The Act does not address the Massachusetts tax treatment of
dividends paid by Pioneer Massachusetts Double Tax-Free Fund that are designated
and treated as long-term  capital gains for federal income tax purposes,  and it
is  accordingly  not  clear  what tax rate  will  apply  to such  dividends  for
Massachusetts tax purposes for taxable years beginning after 1995.
    

         Shareholders  should consult their own tax advisers with respect to the
state, local and foreign tax consequences of investing in the Fund.

11.      DESCRIPTION OF SHARES

         The  Trust'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 and to divide or combine the shares into a greater or lesser
number of shares without thereby changing the proportionate  beneficial interest
in a Fund.  The shares of the Trust are divided  into three  series.  Each share
represents an equal proportionate  interest in a Fund with each other share. The
Trust  reserves the right to create and issue  additional  series of shares,  in
which case, the shares of each series would participate equally in the earnings,
dividends  and assets of the  particular  series,  and would be entitled to vote
separately to approve  investment  advisory  agreements or changes in investment
restrictions, but shareholders of all series would vote together in the election
and  selection  of  Trustees  and  accountants.  Shares of each series vote as a
single series on matters that affect all of the series in substantially the same
manner. As to matters affecting a single series, shares of such series will vote
separately.

         In the  unlikely  event  of  liquidation  of  the  Trust,  each  Fund's
shareholders are entitled to share pro rata, subject to the rights of creditors,
the proceeds of the sale of the assets held in the respective portfolio to which
the shares of the Fund relate minus the liabilities of the Trust attributable to
the respective  series. The Trust currently has only one class of shares of each
series,  but may  establish  other  classes in the future upon such terms as the
Trustees may establish.

         Shareholders  are entitled to one vote for each share held and may vote
in the  election  of  Trustees  and on other  matters  submitted  to meetings of
shareholders.  Although  Trustees are not 


                                      B-24
<PAGE>

elected  annually  by  the   shareholders,   shareholders   have  under  certain
circumstances  the right to remove one or more Trustees.  No material  amendment
may be made to the Trust's  Declaration of Trust without the affirmative vote of
a majority  of its shares.  Shares have no  pre-emptive  or  conversion  rights.
Shares  are  fully  paid and  non-assessable,  except as set  forth  below.  See
"Certain Liabilities."

12.      CERTAIN LIABILITIES

         As a Massachusetts  business trust, the Trust's operations are governed
by its  Declaration  of Trust dated November 6, 1992, a copy of which is on file
with  the  office  of  the  Secretary  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 Trust and requires that notice of such
disclaimer be given in each agreement,  obligation or instrument entered into or
executed  by the  Trust or its  Trustees.  Moreover,  the  Declaration  of Trust
provides for the  indemnification out of Trust property of any shareholders held
personally  liable for any  obligations of the Trust.  The  Declaration of Trust
also  provides  that the Trust shall,  upon  request,  assume the defense of any
claim made  against  any  shareholder  for any act or  obligation  of a 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 Trust  itself will be unable to
meet its  obligations.  In light of the nature of the Trust's  business  and the
nature and amount of its assets,  the  possibility  of the  Trust's  liabilities
exceeding its assets, and therefore a shareholder's risk of personal  liability,
is remote.

         The  Declaration  of  Trust  further  provides  that  the  Trust  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 Trust.  The  Declaration of Trust does not authorize the Trust 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.      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 a Fund deposited by the applicant under this 
    


                                      B-25
<PAGE>

Plan.  The  applicant  must deposit or purchase for deposit with PSC shares of a
Fund having a total value of not less than  $10,000.  Periodic  checks of $50 or
more will be sent to the applicant,  or any person designated by him, monthly or
quarterly.

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

         SWP  payments are made from the  proceeds of the  redemption  of shares
deposited  under the SWP in a SWP account.  To the extent that such  redemptions
for periodic  withdrawals  exceed dividend income reinvested in the SWP account,
such  redemptions  will reduce and may  ultimately  exhaust the number of shares
deposited in the SWP account. 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 capital. Withdrawals
are taxable transactions.

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

14.      LETTER OF INTENTION

         Purchases of $100,000 or over (excluding any reinvestments of dividends
and capital gains  distributions)  made within a 13-month  period  pursuant to a
Letter of  Intention  provided to PFD will qualify for a reduced  sales  charge.
Such  reduced  sales charge will be the charge that would be  applicable  to the
purchase of all shares  purchased  during  such  13-month  period  pursuant to a
Letter of Intention had such shares been purchased all at once.  For example,  a
person who signs a Letter of Intention  providing  for a total  investment  in a
Fund's shares of $100,000  over a 13-month  period would be charged at the 2.50%
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 a Fund and other  Pioneer  Funds  except
Pioneer Money Market Trust as of the date of the Letter of Intention as a credit
toward  determining  the  applicable  scale of sales charge for the shares to be
purchased under the Letter of Intention.

                                      B-26
<PAGE>

         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  set  forth in  detail  in the  Account
Application carefully before signing.

15.      DETERMINATION OF NET ASSET VALUE

         The net asset  value per  share of each  Fund is  determined  as of the
close of regular  trading on the New York Stock Exchange  (currently  4:00 p.m.,
Eastern  Time) on each day on which  the New  York  Stock  Exchange  is open for
trading.  As of the date of this SAI,  the New York Stock  Exchange  is open for
trading  every  weekday  except for the  following  holidays:  New  Year's  Day,
Presidents'  Day,  Good  Friday,  Memorial  Day,  Independence  Day,  Labor Day,
Thanksgiving  Day and  Christmas.  The net asset value per share of each Fund is
also  determined on any other day in which the level of trading in its portfolio
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 a Fund become effective and no
shares  are  tendered  for  redemption,  the net  asset  value  per share is not
determined.

         The net  asset  value  per share of a Fund is  computed  by taking  the
amount of the value of all of its assets, less its liabilities,  and dividing it
by the number of outstanding shares. The Board of Trustees has directed that the
fair  market  value of the  Funds'  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 amortized  cost,  which  approximates
market value.

16.      INVESTMENT RESULTS

         Each Fund's yield quotations and average annual total return quotations
as they may appear in the Prospectus,  this SAI or in advertising are calculated
by standard methods prescribed by the Securities and Exchange Commission.

                                      B-27
<PAGE>

         Standardized Yield Quotations

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

                  YIELD  = 2[  (a-b +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 a 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 the settlement  date, and with
respect  to  obligations  sold  during the month,  the sale price  (plus  actual
accrued interest, if any) between the trade and settlement dates;

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

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

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

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

                                      B-28
<PAGE>

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

   
         The Funds' yields for the 30-day period ending  September 30, 1995 were
as follows:

Pioneer California Double Tax-Free Fund                  4.97%
Pioneer New York Triple Tax-Free Fund                    4.68%
Pioneer Massachusetts Double Tax-Free Fund               4.80%
    

During this period, PMC temporarily agreed to reduce its management fee and made
other  arrangements  to limit certain other  expenses of the Funds.  Had PMC not
done so the yields for the same period would have been:

   
Pioneer California Double Tax-Free Fund                  3.19%
Pioneer New York Triple Tax-Free Fund                    2.28%
Pioneer Massachusetts Double Tax-Free Fund               2.52%
    

         Taxable Equivalent Yield

         The Funds may also from time to time advertise their taxable equivalent
yield which is determined by dividing that portion of a Fund's yield (calculated
as described above) that is tax exempt by one minus the combined federal,  state
and,  if  applicable,  city  tax  rates,  adjusted  to  take  into  account  the
deductibility  of state and, if  applicable,  city income taxes on an investor's
federal  tax  returns  and adding the  product to that  portion,  if any, of the
Fund's yield that is not tax exempt.

   
         The Funds'  taxable  equivalent  yields for the  30-day  period  ending
September 30, 1995 were:

     Pioneer California Double Tax-Free Fund
            (assuming a combined federal and California
            State personal income tax rate of 46.24%):            9.24%

     Pioneer New York Triple Tax-Free Fund
            (assuming a combined federal and New York
            State personal income tax rate of 44.19%):            8.39%
    

                                      B-29
<PAGE>

   
            (assuming a combined federal, New York State
            and New York City personal income tax rate
            of 46.88%):                                           8.81%

     Pioneer Massachusetts Double Tax-Free Fund
            (assuming a combined federal and Massachusetts
            State personal income tax rate of 46.85%):            9.03%
    

Had PMC not  agreed  temporarily  to reduce  its  management  fee and make other
arrangements  to limit certain other expenses of the Funds,  the yields on which
these taxable  equivalent yields are computed,  and thus the taxable  equivalent
yields themselves, would have been:

   
    Pioneer California Double Tax-Free Fund
           (assuming a combined federal and California
           State personal income tax rate of 46.24%):             5.94%

    Pioneer New York Triple Tax-Free Fund
           (assuming a combined federal and New York
           State personal income tax rate of 44.19%):             4.09%

           (assuming a combined federal, New York State
           and New York City personal income tax rate
           of 46.88%):                                            4.24%

    Pioneer Massachusetts Double Tax-Free Fund
           (assuming a combined federal and Massachusetts
           State personal income tax rate of 46.85%):             4.75%
    

See "Investment Results-Standardized Yield Quotations," above.

         For a  description  of how to  compare  yields on  municipal  bonds and
taxable  securities and of certain other  assumptions made in computing  taxable
equivalent  yields, see the Taxable Equivalent Formula set forth in the Appendix
to the Funds' prospectus.

         Standardized Average Annual Total Return Quotations

         Average  annual  total  return  quotations  are computed by finding the
average  annual  compounded  rates of return  that  would  cause a  hypothetical
investment  made on the first  day of a  designated  period to equal the  ending
redeemable  value  of  such  hypothetical  investment  on  the  last  day of the
designated period in accordance with the following formula:

                  P(1+T) n = ERV

                                      B-30
<PAGE>

Where:   P        =        a hypothetical initial payment of $1,000

         T        =        average annual total return

         n        =        number of years

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

The  computation  above assumes that all dividends and  distributions  made by a
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%.

         Other Quotations, Comparisons, and General Information

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

         In addition, from time to time, quotations from articles from financial
publications,  such as those listed  above,  may be used in  advertisements,  in
sales literature, or in reports to the shareholders of the Funds.

         One of the  primary  methods  used to measure a Fund's  performance  is
"total return." "Total return" will normally  represent the percentage change in
value of an account, or of a hypothetical  investment in a Fund, over any period
up to the  lifetime  of the  Fund.  Unless  otherwise  indicated,  total  return
calculations  will 


                                      B-31
<PAGE>

assume the deduction of the maximum sales charge of 3.50% and 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  calculations  that do not reflect the  reduction of sales  charges
will be higher than those that do reflect such charges.

   
         Each Fund's  total  returns for the one year and  life-of-fund  periods
ending September 30, 1995 are as follows:
    

                                                   Since Inception on
                                       One Year     February 9, 1993

   
Pioneer California Double
 Tax-Free Fund                           7.61%           2.50%
Pioneer New York Triple
 Tax-Free Fund                           7.12%           3.08%
Pioneer Massachusetts Double
 Tax-Free Fund                           8.46%           3.45%
    

         During these periods,  PMC temporarily  agreed to reduce its management
fee and made other  arrangements  to limit certain other  expenses of the Funds.
Had PMC not done so, the total returns for the period would have been lower.

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

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

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

performance, and figures for all bond funds include the maximum applicable sales
charge.  A  shareholder's  actual yield and total return will vary with changing
market  conditions.  The value of shares (except for Pioneer money market funds,
which seek a stable  $1.00 share  price) will also vary and may be worth more or
less at redemption than their original cost.

                       Description of Municipal Securities

Municipal Bonds

         Municipal  Bonds  include debt  obligations  issued to obtain funds for
various public  purposes,  including the  construction of a wide range of public
facilities such as bridges,  highways,  housing,  mass transportation,  schools,
streets and water and sewer  works.  Other public  purposes for which  Municipal
Bonds may be issued include refunding outstanding  obligations,  obtaining funds
for general  operating  expenses,  and  obtaining  funds to loan to other public
institutions.

         The two  principal  classifications  of  Municipal  Bonds are  "general
obligation" and "revenue"  bonds.  General  obligation  bonds are secured by the
issuer's  pledge of its  faith,  credit  and taxing  power for the  payment  for
principal  and  interest.  The  payment of such bonds may be  dependent  upon an
appropriation  by  the  issuer's   legislative  body.  The  characteristics  and
enforcement of general  obligation bonds vary according to the law applicable to
the particular issuer.  Revenue bonds are payable only from the revenues derived
from a particular  facility or class of facilities  or, in some cases,  from the
proceeds of a special excise or other  specific  revenue  source.  There are, of
course,  variations in the security of Municipal Bonds, both within a particular
classification and between classifications, depending on numerous factors.

         The yields on  Municipal  Bonds are  dependent on a variety of factors,
including  general  money  market  conditions,  supply and  demand  and  general
conditions  of the Municipal  Bond market,  size of a particular  offering,  the
maturity  of the  obligation  and  rating of the issue.  The  ratings of Moody's
Investor  Service,  Inc.  and  Standard  & Poor's  corporation  represent  their
opinions as to the quality of various  Municipal Bonds. It should be emphasized,
however,  that  ratings are not  absolute  standards  of quality.  Consequently,
Municipal  Bonds with the same  maturity,  coupon and rating may have  different
yields while Bonds of the same  maturity and coupon with  different  ratings may
have the same yield.

Municipal (Tax-Exempt) Notes

         Municipal   (Tax-Exempt)  Notes  generally  are  used  to  provide  for
short-term  capital  needs and  generally  have  maturities of one year or less.
These Notes include:

         1. Project  Notes.  Project Notes are backed by an agreement  between a
local issuing agency and the Federal Department of Housing and Urban Development
("HUD") and carry a United  States  Government  guarantee.  These notes  provide
financing  for a wide  range


                                      -1A-

<PAGE>

of financial assistance programs for housing,  redevelopment,  and related needs
(such as low-income housing programs and urban renewal programs.)  Although they
are the primary  obligations of the local public housing agencies or local urban
renewal agencies,  the HUD agreement provides for the additional security of the
full  faith and credit of the United  States  Government.  Payment by the United
States  pursuant  to its full  faith and credit  obligation  does not impair the
tax-exempt character of the income from Project Notes.

         2. Tax Anticipation Notes. Tax Anticipation Notes are issued to finance
working  capital  needs  of  municipalities.   Generally,  they  are  issued  in
anticipation of various tax revenues,  such as income,  sales,  use and business
taxes, and are specifically payable from these particular future tax revenues.

         3. Revenue Anticipation Notes. Revenue Anticipation Notes are issued in
expectation of receipt of specific types of revenue,  other than taxes,  such as
federal revenues available under Federal Revenue Sharing Programs.

         4. Bond  Anticipation  Notes.  Bond  Anticipation  Notes are  issued to
provide interim  financing  until  long-term bond financing can be arranged.  In
most cases,  the long-term bonds then provide the funds for the repayment of the
Notes.

         5. Construction Loan Notes. Construction Loan Notes are sold to provide
construction financing.  Permanent financing,  the proceeds of which are applied
to the payment of Construction Loan Notes, is sometimes provided by a commitment
by  the  Government   National  Mortgage   Association  to  purchase  the  loan,
accompanied  by a commitment  by the Federal  Housing  Administration  to insure
mortgage  advances  thereunder.  In  other  instances,  permanent  financing  is
provided by the commitments of banks to purchase the loan.

                     Description of Municipal Bond Ratings1

                        Moody's Investors 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 produced 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 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.


- --------
1 The  ratings  indicated  herein are  believed  to be the most  recent  ratings
available  at the  date of  this  SAI 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 ratings  indicated do not  necessarily  represent  ratings which will be
given to these  securities  on the date of the Fund's fiscal  year-end. 

2 Rates 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.

                        Standards & Poor's Ratings Group3

         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.

         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.












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

                                   APPENDIX C

                    Description of Certain Other Investments

         U.S.  Government  Obligations  - are issued by the Treasury and include
bills,   certificates  of   indebtedness,   notes,   and  bonds.   Agencies  and
instrumentalities  of the U.S. Government are established under the authority of
an act of Congress and include,  but are not limited to, the Government National
Mortgage Association, the Tennessee Valley Authority, the Bank for cooperatives,
the Farmers Home  Administration,  Federal Home Loan Banks, Federal Intermediate
Credit Banks, Federal Land Banks, and the Federal National Mortgage Association.

         Certificates  of  Deposit  -  are  certificates  issued  against  funds
deposited  in a  commercial  bank,  are for a  definite  period of time,  earn a
specified rate of return, and are normally negotiable.

         Bankers'  Acceptances  - are  short-term  credit  instruments  used  to
finance  the  import,  export,  transfer  or storage  of goods.  They are termed
"accepted" when a bank guarantees their payment at maturity.

         Repurchase  Agreements - are  agreements by which a person  purchases a
security  and  simultaneously  commits to resell that  security to the seller (a
member bank of the Federal Reserve System or recognized securities dealer) at an
agreed upon price on an agreed upon date  within a number of days  (usually  not
more than  seven)  from the date of  purchase.  The resale  price  reflects  the
purchase price plus an agreed upon market rate of interest which is unrelated to
the coupon rate or maturity of the purchased  security.  A repurchase  agreement
involves  the  obligation  of the seller to pay the  agreed  upon  price,  which
obligation is in effect secured by the value of the underlying security, usually
U.S. Government or Government agency issues. Under the Investment Company Act of
1940,  repurchase  agreements are considered to be loans by the Fund. The Fund's
risk is limited to the  ability of the seller to pay the agreed  upon  amount on
the  delivery  date.  In the  opinion  of the  Fund's  adviser  this risk is not
material; if the seller defaults, the underlying security constitutes collateral
for the seller's  obligation to pay although the Fund may incur certain costs in
liquidating  this  collateral  and in  certain  cases  may not be  permitted  to
liquidate this collateral. The fixed income research department of PMC maintains
an  approved  list  of   repurchase   agreement   sellers   meeting  the  Funds'
creditworthiness  standards and the Trust's Board of Trustees  reviews this list
periodically.

                               INDEX DESCRIPTIONS

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

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

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

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

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

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

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

<PAGE>

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

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

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

MSCI
Morgan  Stanley  Capital  International   Indices,   developed  by  the  Capital
International  S.A., are based on share prices of some 1470 companies  listed on
the stock exchanges around the world.

Countries in the MSCI EAFE Portfolio are:
Australia;  Austria;  Belgium;  Denmark;  Finland;  France;  Germany; Hong Kong;
Italy;  Japan;  Netherlands;  N.  Zealand;  Norway;  Singapore/Malaysia;  Spain;
Sweden; Switzerland; United Kingdom.

6 MONTH CDs
Data sources include the Federal Reserve Bulletin and The Wall Street Journal.

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

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

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

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

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

RUSSELL 2000 SMALL STOCK INDEX
Index of the 2,000 smallest  stocks in the Russell 3000 Index (TM); the smallest
company has a market capitalization of approximately $13 million.

Item 27. Indemnification.

         Except  for  the   Declaration   of  Trust  dated   November  6,  1992,
establishing  the  Registrant as a Trust under  Massachusetts  law,  there is no
contract,  arrangement or statute under which any director, officer, underwriter
or affiliated  person of the Registrant is insured or  indemnified.  The Amended
and Restated  Declaration  of Trust  provides that no Trustee or officer will be
indemnified  against any liability to which the  Registrant  would  otherwise be
subject by reason of or for willful misfeasance,  bad faith, gross negligence or
reckless disregard of such person's duties.

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

                                      C-3

<PAGE>

counsel the matter has been settled by controlling precedent,  submit to a court
of appropriate  jurisdiction the question whether such  indemnification by it is
against  public policy as expressed in the Act and will be governed by the final
adjudication of such issue.

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

this  Declaration,  the presumption shall be in favor of a grant of power to the

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,

subdivision,    or   any   governmental   or   quasi-governmental    agency   or
instrumentality;  and the Trustees shall be deemed to have the foregoing  powers

the Fundamental Restrictions be amended.

trade in and deal in, to acquire any rights or options to  purchase or sell,  to

otherwise subjecting as security the Trust Property; and to endorse,  guarantee,

         (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

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.

                                      -5-
<PAGE>

         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
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 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.

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
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 shallobe  pending or threatened to be brought
before any court, administrative agency or other adjudicatory body.

independent  contractors  of the Trust  against all claims  arising by reason of

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,  profit-sharing,  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

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

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

therewith,  including those of litigation,  and such power shall include without

<PAGE>

proceeding,  dispute, claim or demand,  derivative or otherwise,  brought by any

         Section 2.12. Number of Trustees.  The number of Trustees shall be such

         Section 2.13.  Election and Term.  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
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

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 two) for cause,  by
the action of two-thirds of the remaining Trustees or by action 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

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

         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
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 two (2) Trustees Personally exercise the powers granted to
the  Trustees  under  this  Declaration  except  as herein  otherwise  expressly

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

Adviser may nonetheless  serve as Investment  Adviser with respect to any Series
whose Shareholders approve such contract.

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  contract  shall  undertake to furnish  transfer

and  conditions  as  the  Trustees  may  in  their   discretion   determine  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

the Custodian to employ one or more subcustodians,  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 subcustodian,  to hold securities and other assets of the
Trust  and to  perform  the acts  and  services  of the  Custodian,  subject  to

                                      -12-
<PAGE>

         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

         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.

         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,




                                      -13-
<PAGE>

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
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 

                                      -14-
<PAGE>

         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;

                  (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 

                                      -15-
<PAGE>

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

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

                                      -16-
<PAGE>

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
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, $.01
par value per share. 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

                                      -17-
<PAGE>

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
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 



                                      -18-
<PAGE>

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
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 



                                      -19-

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.l3;  (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
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 12b-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  By-laws 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  

                                      -20-

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 By-laws 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  (101) 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
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 three Series designated as: "Pioneer California
Double Tax-Free Fund," "Pioneer Massachusetts Double Tax-Free Fund" and "Pioneer
New York Triple Tax-Free Fund," respectively (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 consist 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

                                      -21-
<PAGE>

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
         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.

                                      -22-
<PAGE>

                 (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
         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 (l) as to any matter with  respect to which a
         separate  vote of any Series or Class is required by the 1940 Act or is
         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  (l) 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.

<PAGE>

                 (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 further 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 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 


                                      -25-
<PAGE>

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
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.

                                      -26-
<PAGE>

         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 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 


                                      -27-
<PAGE>

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,
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 


                                      -28-
<PAGE>

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 daily  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 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  


                                      -29-
<PAGE>

declared  as of a day on  which  Boston  banks  are not open  for  business,  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.

         Section  7.3.  Determination  of Net Income;  Constant Net Asset Value;
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


                                      -30-
<PAGE>

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.

         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.

                                      -31-
<PAGE>

         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
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 


                                      -32-
<PAGE>

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.

         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  


                                      -33-
<PAGE>

of this  Declaration;  and (iii) to  eliminate  or modify any  provision of this
Declaration  which (a)  incorporates,  memorializes  or sets  forth an  existing
requirement  imposed  by or under  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
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,  


                                      -34-
<PAGE>

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.  With the  approval  of the  holders of a
majority of the Shares of the Trust or a Series thereof outstanding and entitled
to vote,  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 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  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 


                                      -35-
<PAGE>

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.

         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 tact 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


                                      -36-
<PAGE>

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
day of November, 1992.

having its principal office at 60 State Street, Boston, Massachusetts 02109 (the
"Trust"),  hereby  certifies to the  Secretary of State of the  Commonwealth  of

Trustees of the Trust in accordance  with the  provisions of the  Declaration of
Trust and  By-Laws of the  Trust,  the  following  individuals  were  elected as

          authorized  by the Trustees  pursuant to the  Declaration  of Trust or
          these By-Laws, or for the payment of any expense or liability incurred

     (e)  The  Custodian(s)  shall make deliveries of securities and payments of
          cash only  upon  written  instructions  signed  or  initialed  by such

          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

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  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.

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.

                             UNDERWRITING AGREEMENT


         THIS UNDERWRITING  AGREEMENT,  dated this 19th day of February, 1993 by
and between  Pioneer  Tax-Free State Series Trust  ("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 end,  diversified,  management  investment  company  under  the  Investment
Company Act of 1940, as amended (the "1940 Act"),  and has filed a  registration
statement  (the  "Registration  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 in the  purchase  and sale of
securities  both as a broker and a dealer and is registered  as a  broker-dealer
with the Commission and is a member 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

         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.

<PAGE>

         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
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 respect  thereto,  including,
without   limitation,   rights   of   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  shall  terminate  on June 30, 1994 if its terms and
renewal  have not been  approved by a majority  vote of the  Trustees of Pioneer
voting in person,  including a majority 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  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.

                                      -2-
<PAGE>

         5. 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
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.  Nothing contained
herein shall relieve Pioneer of any obligation under its management  contract or
any other contract with any affiliate of the Underwriter.

         6.  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 or 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.

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

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

         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.

                                 SALES AGREEMENT

Gentlemen:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

                               CUSTODIAN AGREEMENT

         AGREEMENT made this _____ day of  ______________,  1993 between PIONEER
CALIFORNIA  DOUBLE TAX FREE FUND (the "Fund") and Brown Brothers  Harriman & Co.

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

         l.  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 

<PAGE>

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
(l) 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

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 Y on Page 18, insofar as funds are available for the purpose, to pay for

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

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 


                                      -3-
<PAGE>

in  Section  2C,  and  may  surrender  securities  for  a  different  number  of
certificates  or  instruments  representing  the same  number  of shares or same
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 (l) in cash, by a certified check,  bank cashier's

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

may be responsible for handling such options transactions.

         K.  Borrowings  - Upon  receipt  of  proper  instructions,  to  deliver

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

                                      -9-

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

any such agent shall be qualified to act as a custodian of the Fund  pursuant to
the Investment Company Act of 1940 and the rules and regulations thereunder), in
a Securities  System provided that such securities 


                                      -14-

provided  that the  instructions  relating to such  disposition  shall include a

by the Fund for any  violation  which  occurs  in the  course  of  carrying  out
instructions  given by the Fund of any investment  limitations to which the Fund
is  subject or other  limitations  with  respect  to the  Fund's  powers to make
expenditures,  encumber securities, borrow or take similar actions affecting the
Fund.

         X. Restricted  Securities.  Notwithstanding any other provision of this
Agreement,  the Custodian  shall not be liable for failure to take any action in
respect of a "restricted  security" (as hereafter  defined) if the Custodian has
not received Proper  Instructions to take such action (including but not limited
to the  failure  to  exercise  in a timely  manner  any right in  respect of any
restricted  security) unless the Custodian's  responsibility to take such action
is set forth in a  writing,  agreed  upon by the  Custodian  and the Fund or the
investment adviser of the Fund, 


                                      -17-
<PAGE>

which  specifies  particular  actions the  Custodian is to take  without  Proper
Instructions  in respect of specified  rights and  obligations  pertaining  to a
particular restricted security.  Further, the Custodian shall not be responsible
for transmitting to the Fund information concerning a restricted security,  such
as with respect to exercise  periods and expiration dates for rights relating to
the restricted  security,  except such information which the Custodian  actually
receives or which is  published in a source  which is publicly  distributed  and
generally  recognized as a major source of information with respect to corporate
actions of securities  similar to the particular  restricted  security.  As used
herein, the term "restricted securities" shall mean securities which are subject
to  restrictions on transfer,  whether by reason of contractual  restrictions or
federal,  state or foreign  securities or similar laws, or securities which have
special  rights or contractual  features  which do not apply to publicly  traded
shares of, or comparable interests representing, such security.

         Y. Proper  Instructions - Proper instructions shall mean a tested telex
from the Fund or a written  request,  direction,  instruction  or  certification
signed or  initialled  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 


                                      -18-
<PAGE>

delivery of securities or the payment of funds to an authorized signatory of the
Fund shall be signed by such person.  Those  persons  authorized  to give proper
instructions  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.

                                      -19-
<PAGE>

         Proper  instructions  may  include  communications   effected  directly
between  electro-mechanical  or  electronic  devices or systems,  in addition to
tested telex,  provided that the Fund and the Custodian agree to the use of such
device or system.

         z.  Segregated  Account - The  Custodian  shall upon  receipt of proper
instructions  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 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  


                                      -20-
<PAGE>

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  (l) 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

                                      -21-
<PAGE>

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 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,  


                                      -22-
<PAGE>

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 


                                      -23-
<PAGE>

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.

         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  


                                      -24-
<PAGE>

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.

         5.  Powers  and  Duties of the  Custodian  with  Respect to its Role as
Financial  Agent:  The Fund hereby also  appoints  the  Custodian  as the Fund's
financial  agent.  With  respect to the  appointment  as  financial  agent,  the
Custodian shall have and perform the following powers and duties:

         A. Records - To create,  maintain  and retain such records  relating to
its  activities and  obligations  under this Agreement as are required under the
Investment  Company  Act of  1940  and  the  rules  and  regulations  thereunder
(including  Section 31 thereof and Rules 31a-1 and 31a-2  thereunder)  and under
applicable  Federal and State tax laws. All such records will be the property of
the Fund and in the event of termination of this Agreement shall be delivered to
the successor custodian.

         B. Accounts - To keep books of account and render statements, including
interim monthly and complete quarterly 


                                      -25-
<PAGE>

financial  statements,  or  copies  thereof,  from  time to  time as  reasonably
requested by proper instructions.

         C.  Access  to  Records  - The  books  and  records  maintained  by the
Custodian  pursuant  to  Sections  5A  and 5B  shall  at all  times  during  the
Custodian's  regular  business hours be open to inspection and audit by officers
of, attorneys for and auditors  employed by the Fund and by employees and agents
of the Securities and Exchange  Commission,  provided that all such  individuals
shall observe all security  requirements of the Custodian  applicable to its own
employees  having  access to  similar  records  within  the  Custodian  and such
regulations as may be reasonably imposed by the Custodian.

         D. Disbursements - Upon receipt of proper instructions, to pay or cause
to be paid,  insofar as funds are available for the purpose,  bills,  statements
and  other  obligations  of the Fund  (including  but not  limited  to  interest
charges,  taxes,  management fees,  compensation to Fund officers and employees,
and other operating expenses of the Fund).

         6.       Standard of Care and Related Matters:

         A.  Liability of the  Custodian  with  Respect to Proper  Instructions;
Evidence of  Authority,  Etc. The  Custodian  shall not be liable for any action
taken or omitted in  reliance  upon  proper  instructions  believed  by it to be
genuine  or upon any other  written  notice,  request,  direction,  instruction,
certificate or 


                                      -26-
<PAGE>

other instrument  believed by it to be genuine and signed by the proper party or
parties.

         The  Secretary or Assistant  Secretary of the Fund shall certify to the
Custodian the names, signatures and scope of authority of all persons authorized
to give  proper  instructions  or any other  such  notice,  request,  direction,
instruction,  certificate  or  instrument  on behalf of the Fund,  the names and
signatures of the officers of the Fund, the name and address of the  Shareholder
Servicing Agent, and any resolutions,  votes,  instructions or directions of the
Fund's Board of Directors or Trustees or  shareholders.  Such certificate may be
accepted and relied upon by the  Custodian as  conclusive  evidence of the facts
set forth  therein and may be  considered in full force and effect until receipt
of a similar certificate to the contrary.

         So long as and to the extent that it is in the  exercise of  reasonable
care,  the  Custodian  shall  not be  responsible  for the  title,  validity  or
genuineness  of any  property  or evidence  of title  thereto  received by it or
delivered by it pursuant to this Agreement.

         The Custodian shall be entitled, at the expense of the Fund, to receive
and act upon  advice of (i)  counsel  regularly  retained  by the  Custodian  in
respect of custodian  matters,  (ii)  counsel for the Fund,  or (iii) such other
counsel  as the Fund and the  Custodian  may agree  upon,  with  respect  to all
matters,  and the 


                                      -27-
<PAGE>

Custodian shall be without  liability for any action reasonably taken or omitted
pursuant to such advice.

         B. Liability of the Custodian with Respect to Use of Securities  System
- - With respect to the portfolio securities,  cash and other property of the Fund
held by a Securities  System, the Custodian shall be liable to the Fund only for
any loss or damage to the Fund resulting  from use of the  Securities  System if
caused by any  negligence,  misfeasance or misconduct of the Custodian or any of
its  agents  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  terms  set forth in the  subcustodian  agreement  between  the
Custodian  and the  Subcustodian  (or in the  subcustodian  agreement  between a
Subcustodian  and any secondary  Subcustodian),  the  Subcustodian (or


                                      -28-
<PAGE>

secondary Subcustodian) has failed to perform in accordance with the standard of
conduct  imposed under such  subcustodian  agreement as determined in accordance
with the law which is  adjudicated  to govern such  agreement  and in accordance
with any  determination  of any  court  as to the  duties  of said  Subcustodian
pursuant to said  agreement.  The Custodian shall also be liable to the Fund for
its own negligence in 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 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
of the Fund is  registered  against any  


                                      -29-
<PAGE>

liability the Custodian or such nominee 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  directly or  indirectly  from the fact
that  portfolio  securities  or other  property of the Fund is registered in the
name of the Custodian or such nominee.

         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 


                                      -30-
<PAGE>

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 Fund,  including in connection  with foreign  exchange  contracts or options
(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  


                                      -31-
<PAGE>

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.

         H. Powers of  Attorney - Upon  request,  the Fund shall  deliver to the
Custodian  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 any  Subcustodian  of  their  respective  obligations  under  this
Agreement or any applicable subcustodian agreement.

         7.  Compensation  of the Custodian:  The Fund shall pay the Custodian a
custody  fee based on such fee  schedule as may from time to time be agreed upon
in writing by the  Custodian and the Fund.  Such fee,  together with all amounts
for which the Custodian is to be reimbursed in accordance with Section 6D, shall
be billed to the Fund in such a manner as to  permit  payment  by a direct  cash
payment to the Custodian.

                                      -32-
<PAGE>

         8. Termination;  Successor Custodian:  This Agreement shall continue in
full force and effect  until  terminated  by either  party by an  instrument  in
writing  delivered  or  mailed,  postage  prepaid,  to  the  other  party,  such
termination to take effect not sooner than seventy five (75) days after the date
of such delivery or mailing.  In the event of termination the Custodian shall be
entitled  to  receive  prior to  delivery  of the  securities,  funds  and other
property  held by it all accrued fees and  unreimbursed  expenses the payment of
which is  contemplated  by  Sections  6D and 7,  upon  receipt  by the Fund of a
statement setting forth such fees and expenses.

         In the event of the appointment of a successor custodian,  it is agreed
that the funds and securities owned by the Fund and held by the Custodian or any
Subcustodian  shall be delivered to the successor  custodian,  and the Custodian
agrees to cooperate  with the Fund in execution of documents and  performance of
other  actions  necessary  or  desirable in order to  substitute  the  successor
custodian for the Custodian under this Agreement.

         9. Amendment:  This Agreement  constitutes the entire understanding and
agreement of the parties hereto with respect to the subject  matter  hereof.  No
provision of this  Agreement may be amended or terminated  except by a statement
in writing  signed by the party  against which  enforcement  of the amendment or
termination is sought.

interpretative  of or in addition to the  provisions of this Agreement as may in

                               CUSTODIAN AGREEMENT

         AGREEMENT made this _____ day of  ______________,  1993 between PIONEER
NEW YORK  TRIPLE TAX FREE FUND (the  "Fund") and Brown  Brothers  Harriman & Co.

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

<PAGE>

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

         D.  Purchases  - Upon  receipt  of Proper  Instructions,  as defined in
Section Y on Page 18, insofar as funds are available for the purpose, to pay for

<PAGE>

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

                                      -3-
<PAGE>

to foreign  currency  exchange rates,  derivatives and similar  securities,  the

terms of any reorganization or protective plan. Without proper instructions, the
Custodian may surrender securities in temporary form for definitive  securities,
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
certificates  or  instruments  representing  the same  number  of shares or same
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

                                      -4-
<PAGE>

the Custodian 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,

                                      -7-
<PAGE>

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 be  designated  by the Fund in such  instructions  (any  such  bank or trust
company so  designated  by the Fund being  referred to  hereafter as a ("Banking
Institution"),  provided that such account(s) (hereinafter collectively referred
to as "demand deposit bank accounts")  shall be in the name of the Custodian for
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 pursuant to proper instructions.  Such deposits may be placed with the
Custodian or with  Subcustodians  or other Banking  Institutions as the Fund may

                                      -8-
<PAGE>

determine.  Deposits may be denominated in U.S.  Dollars or other currencies and
need not be  evidenced  by the  issuance  or delivery  of a  certificate  to the
Custodian, provided that the Custodian shall include in its records with respect
to the assets of the Fund appropriate  notation as to the amount and currency of
each 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  account  of the  Fund.  Such  transactions  may be  undertaken  by the
Custodian   with  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


                                      -9-
<PAGE>

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 other banks as described in
Section 2L of this agreement.  Upon receipt of proper  instructions,  to receive
and retain  confirmations  evidencing the purchase or sale of a futures contract
or an option on a futures  contract by the Fund;  to deposit  and  maintain in a
segregated account, for the benefit of any futures commission merchant or to pay
to such futures commission  merchant,  assets designated by the fund as initial,
maintenance  or  variation  margin  deposits   intended  to  secure  the  Fund's
performance of its obligations under any futures 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.

         O.  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  


                                      -10-
<PAGE>

of the  collateral,  if any, for such  borrowing,  provided that for stock loans
secured by cash collateral the Custodian's instructions to 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.

         P.  Collections  - To collect,  receive and deposit in said  account or
accounts all income,  payments of principal  and other  payments with respect to
the  securities  held  hereunder,  and in  connection  therewith  to deliver the
certificates  or other  instruments  representing  the  securities to the issuer
thereof or its agent when securities are called, redeemed,  retired or otherwise
become payable; provided, 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.  securities   depositories  and  clearing  agencies  or,  with  respect  to
securities  referred to in clause  (iii) of the last  sentence of Section 2D, in
accordance with generally accepted trade practice; (ii) to execute ownership and
other  certificates  and  affidavits  for all federal and state tax  purposes in
connection 


                                      -11-
<PAGE>

with receipt of income or other  payments with respect to securities of the Fund
or in  connection  with  transfer of  securities,  and (iii)  pursuant to proper
instructions to take such other actions with respect to collection or receipt of

instructions  from the Fund,  or upon  receipt of  instructions  from the Fund's
shareholder  servicing agent or agent with comparable  duties (the  "Shareholder
Servicing  Agent") (given by such person or persons and in such manner on behalf
of the  Shareholder  Servicing  Agent as the Fund  shall have  authorized),  the
Custodian shall release funds or securities to the  Shareholder  Servicing Agent
or otherwise apply funds or securities, insofar as available, for the payment of
dividends or other  distributions to Fund  shareholders.  Upon receipt of proper
instructions from the Fund, or upon receipt of instructions from the Shareholder
Servicing Agent (given by such person or persons and in such manner on behalf of
the  Shareholder  Servicing  Agent  as the  Fund  shall  have  authorized),  the
Custodian  shall  release  funds or  securities,  insofar as  available,  to the
Shareholder  Servicing  Agent or as such  Agent  shall  otherwise  instruct  for
payment to Fund  shareholders  who have  delivered  to such Agent a request  for
repurchase or redemption of their shares of capital stock of the Fund.

forms  of  proxies  and all  notices  of  meetings  and  any  other  notices  or
announcements  affecting  or relating to  securities  owned by the Fund that are
received by the Custodian,  and upon receipt of proper instructions,  to execute
and deliver or cause its nominee to execute  and deliver  such  proxies or other
authorizations  as may be required.  Neither the Custodian nor its nominee shall
vote upon any of such  securities  or execute any proxy to vote  thereon or give
any consent or take any other action with respect  thereto  (except as otherwise
herein provided) unless ordered to do so by proper instructions.

         S.  Nondiscretionary   Details  -  Without  the  necessity  of  express
authorization  from the Fund, (1) to attend to all  nondiscretionary  details in
connection with the sale, exchange,  substitution,  purchase,  transfer or other
dealings with  securities,  funds or other property of the Portfolio held by the
Custodian  except as otherwise  directed  from time to time by the  Directors or
Trustees  of the Fund,  and (2) to make  payments  to itself or others for minor
expenses  of  handling  securities  or  other  similar  items  relating  to  the
Custodian's  duties under this Agreement,  provided that all such payments shall

<PAGE>

         T. Bills - Upon receipt of proper  instructions,  to pay or cause to be

         U. Deposit of Fund Assets in  Securities  Systems - The  Custodian  may
deposit and/or maintain securities owned by the Fund in (i) The Depository Trust
Company,  (ii) any  book-entry  system as  provided  in  Subpart  O of  Treasury
Circular  No. 300, 31 CFR 306,  Subpart B of 31 CFR Part 350, or the  book-entry
regulations of federal agencies substantially in the form of Subpart O, or (iii)
any other domestic  clearing agency  registered with the Securities and Exchange
Commission  under Section 17A of the Securities  Exchange Act of 1934 which acts
as a securities  depository  and whose use the Fund has  previously  approved in
writing  (each  of the  foregoing  being  referred  to in  this  Agreement  as a
"Securities System").  Utilization of a Securities System shall be in accordance
with  applicable  Federal  Reserve Board and Securities and Exchange  Commission
rules and regulations, if any, and subject to the following provisions:

         l) The Custodian may deposit and/or  maintain Fund  securities,  either
directly or through one or more Agents appointed by the Custodian (provided that
any such agent shall be qualified to act as a custodian of the Fund  pursuant to
the Investment Company Act of 1940 and the rules and regulations thereunder), in
a Securities  System provided that such securities

                                      -14-
<PAGE>

are represented in an account  ("Account") of the Custodian or such Agent in the
Securities  System which shall not include any assets of the  Custodian or Agent
other than assets held as a fiduciary, custodian, or otherwise for customers;

         2) The records of the Custodian  with respect to securities of the Fund
which are maintained in a Securities  System shall identify by book-entry  those
securities belonging to the Fund;

         3) The Custodian shall pay for securities  purchased for the account of
the Fund  upon (i)  receipt  of  advice  from the  Securities  System  that such
securities have been transferred to the Account, and (ii) the making of an entry
on the records of the  Custodian  to reflect  such  payment and transfer for the
account  of the Fund.  The  Custodian  shall  transfer  securities  sold for the
account of the Fund upon (i) receipt of advice from the  Securities  System that
payment for such  securities has been  transferred to the Account,  and (ii) the
making of an entry on the records of the  Custodian to reflect such transfer and
payment for the account of the Fund.  Copies of all advices from the  Securities
System of transfers of securities for the account of the Fund shall identify the
Fund,  be  maintained  for the Fund by the  Custodian or an Agent as referred to
above,  and be provided to the Fund at its request.  The Custodian shall furnish
the Fund confirmation of each transfer to or from the account of the Fund in the
form of a written advice or notice and shall furnish to the Fund copies of daily


                                      -15-
<PAGE>

transaction  sheets reflecting each day's  transactions in the Securities System
for the account of the Fund on the next business day;

         4) The Custodian shall provide the Fund with any report obtained by the
Custodian  or  any  Agent  as  referred  to  above  on the  Securities  System's
accounting system,  internal  accounting control and procedures for safeguarding
securities deposited in the Securities System; and the Custodian and such Agents
shall send to the Fund such reports on their own systems of internal  accounting
control as the Fund may reasonably request from time to time.

         5) At the written request of the Fund, the Custodian will terminate the
use of any  such  Securities  System  on  behalf  of the  Fund  as  promptly  as
practicable.

         V. Other  Transfers - Upon receipt of proper  instructions,  to deliver
securities,  funds and other property of the Fund to a  Subcustodian  or another
custodian of the Fund;  and, upon receipt of proper  instructions,  to make such
other disposition of securities, funds or other property of the Fund in a manner
other than or for purposes other than as enumerated elsewhere in this Agreement,
provided  that the  instructions  relating to such  disposition  shall include a
statement  of the  purpose for which the  delivery is to be made,  the amount of
securities  to be  delivered  and the  name of the  person  or  persons  to whom
delivery is to be made.

                                      -16-
<PAGE>

         W.  Investment  Limitations - In performing its duties  generally,  and
more  particularly  in  connection  with  the  purchase,  sale and  exchange  of
securities  made by or for the Fund,  the  Custodian may assume unless and until
notified in writing to the contrary that proper instructions  received by it are
not in  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 the Fund of any investment  limitations to which the Fund
is  subject or other  limitations  with  respect  to the  Fund's  powers to make
expenditures,  encumber securities, borrow or take similar actions affecting the
Fund.

         X. Restricted  Securities.  Notwithstanding any other provision of this
Agreement,  the Custodian  shall not be liable for failure to take any action in
respect of a "restricted  security" (as hereafter  defined) if the Custodian has
not received Proper  Instructions to take such action (including but not limited
to the  failure  to  exercise  in a timely  manner  any right in  respect of any
restricted  security) unless the Custodian's  responsibility to take such action
is set forth in a  writing,  agreed  upon by the  Custodian  and the Fund or the
investment adviser of the Fund, 
                                      -17-
<PAGE>

which  specifies  particular  actions the  Custodian is to take  without  Proper
Instructions  in respect of specified  rights and  obligations  pertaining  to a
particular restricted security.  Further, the Custodian shall not be responsible
for transmitting to the Fund information concerning a restricted security,  such
as with respect to exercise  periods and expiration dates for rights relating to
the restricted  security,  except such information which the Custodian  actually
receives or which is  published in a source  which is publicly  distributed  and
generally  recognized as a major source of information with respect to corporate
actions of securities  similar to the particular  restricted  security.  As used
herein, the term "restricted securities" shall mean securities which are subject
to  restrictions on transfer,  whether by reason of contractual  restrictions or
federal,  state or foreign  securities or similar laws, or securities which have
special  rights or contractual  features  which do not apply to publicly  traded
shares of, or comparable interests representing, such security.

         Y. Proper  Instructions - Proper instructions shall mean a tested telex
from the Fund or a written  request,  direction,  instruction  or  certification
signed or  initialled  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 


                                      -18-
<PAGE>

delivery of securities or the payment of funds to an authorized signatory of the
Fund shall be signed by such person.  Those  persons  authorized  to give proper
instructions  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.

                                      -19-
<PAGE>

         Proper  instructions  may  include  communications   effected  directly
between  electro-mechanical  or  electronic  devices or systems,  in addition to
tested telex,  provided that the Fund and the Custodian agree to the use of such
device or system.

         z.  Segregated  Account - The  Custodian  shall upon  receipt of proper
instructions  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 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 

                                      -20-
<PAGE>

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

                                      -21-
<PAGE>

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 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,  


                                      -22-
<PAGE>

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

                                      -23-
<PAGE>

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.

         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  


                                      -24-
<PAGE>

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.

         5.  Powers  and  Duties of the  Custodian  with  Respect to its Role as
Financial  Agent:  The Fund hereby also  appoints  the  Custodian  as the Fund's
financial  agent.  With  respect to the  appointment  as  financial  agent,  the
Custodian shall have and perform the following powers and duties:

         A. Records - To create,  maintain  and retain such records  relating to
its  activities and  obligations  under this Agreement as are required under the

applicable  Federal and State tax laws. All such records will be the property of
the Fund and in the event of termination of this Agreement shall be delivered to
the successor custodian.

         B. Accounts - To keep books of account and render statements, including
interim monthly and complete quarterly 


                                      -25-

financial  statements,  or  copies  thereof,  from  time to  time as  reasonably
requested by proper instructions.

         C.  Access  to  Records  - The  books  and  records  maintained  by the
Custodian  pursuant  to  Sections  5A  and 5B  shall  at all  times  during  the
Custodian's  regular  business hours be open to inspection and audit by officers
of, attorneys for and auditors  employed by the Fund and by employees and agents
of the Securities and Exchange  Commission,  provided that all such  individuals
shall observe all security  requirements of the Custodian  applicable to its own
employees  having  access to  similar  records  within  the  Custodian  and such
regulations as may be reasonably imposed by the Custodian.

         D. Disbursements - Upon receipt of proper instructions, to pay or cause
to be paid,  insofar as funds are available for the purpose,  bills,  statements
and  other  obligations  of the Fund  (including  but not  limited  to  interest
charges,  taxes,  management fees,  compensation to Fund officers and employees,
and other operating expenses of the Fund).

         6.       Standard of Care and Related Matters:

         A.  Liability of the  Custodian  with  Respect to Proper  Instructions;
Evidence of  Authority,  Etc. The  Custodian  shall not be liable for any action
taken or omitted in  reliance  upon  proper  instructions  believed  by it to be
genuine  or upon any other  written  notice,  request,  direction,  instruction,
certificate or 


                                      -26-
<PAGE>

other instrument  believed by it to be genuine and signed by the proper party or
parties.

         The  Secretary or Assistant  Secretary of the Fund shall certify to the
Custodian the names, signatures and scope of authority of all persons authorized
to give  proper  instructions  or any other  such  notice,  request,  direction,
instruction,  certificate  or  instrument  on behalf of the Fund,  the names and
signatures of the officers of the Fund, the name and address of the  Shareholder
Servicing Agent, and any resolutions,  votes,  instructions or directions of the
Fund's Board of Directors or Trustees or  shareholders.  Such certificate may be
accepted and relied upon by the  Custodian as  conclusive  evidence of the facts
set forth  therein and may be  considered in full force and effect until receipt
of a similar certificate to the contrary.

         So long as and to the extent that it is in the  exercise of  reasonable
care,  the  Custodian  shall  not be  responsible  for the  title,  validity  or
genuineness  of any  property  or evidence  of title  thereto  received by it or
delivered by it pursuant to this Agreement.

         The Custodian shall be entitled, at the expense of the Fund, to receive
and act upon  advice of (i)  counsel  regularly  retained  by the  Custodian  in
respect of custodian  matters,  (ii)  counsel for the Fund,  or (iii) such other
counsel  as the Fund and the  Custodian  may agree  upon,  with  respect  to all
matters,  and the 


                                      -27-
<PAGE>

Custodian shall be without  liability for any action reasonably taken or omitted
pursuant to such advice.

         B. Liability of the Custodian with Respect to Use of Securities  System
- - With respect to the portfolio securities,  cash and other property of the Fund
held by a Securities  System, the Custodian shall be liable to the Fund only for
any loss or damage to the Fund resulting  from use of the  Securities  System if
caused by any  negligence,  misfeasance or misconduct of the Custodian or any of
its  agents  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  terms  set forth in the  subcustodian  agreement  between  the
Custodian  and the  Subcustodian  (or in the  subcustodian  agreement  between a
Subcustodian  and any secondary  Subcustodian),  the  Subcustodian (or 


                                      -28-
<PAGE>

secondary Subcustodian) has failed to perform in accordance with the standard of
conduct  imposed under such  subcustodian  agreement as determined in accordance
with the law which is  adjudicated  to govern such  agreement  and in accordance
with any  determination  of any  court  as to the  duties  of said  Subcustodian
pursuant to said  agreement.  The Custodian shall also be liable to the Fund for
its own negligence in 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 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
of the Fund is  registered  against any  


                                      -29-
<PAGE>

liability the Custodian or such nominee 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  directly or  indirectly  from the fact
that  portfolio  securities  or other  property of the Fund is registered in the
name of the Custodian or such nominee.

         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 


                                      -30-
<PAGE>

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 Fund,  including in connection  with foreign  exchange  contracts or options
(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  


                                      -31-
<PAGE>

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.

         H. Powers of  Attorney - Upon  request,  the Fund shall  deliver to the
Custodian  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 any  Subcustodian  of  their  respective  obligations  under  this
Agreement or any applicable subcustodian agreement.

         7.  Compensation  of the Custodian:  The Fund shall pay the Custodian a
custody  fee based on such fee  schedule as may from time to time be agreed upon
in writing by the  Custodian and the Fund.  Such fee,  together with all amounts
for which the Custodian is to be reimbursed in accordance with Section 6D, shall
be billed to the Fund in such a manner as to  permit  payment  by a direct  cash
payment to the Custodian.

                                      -32-
<PAGE>

         8. Termination;  Successor Custodian:  This Agreement shall continue in
full force and effect  until  terminated  by either  party by an  instrument  in
writing  delivered  or  mailed,  postage  prepaid,  to  the  other  party,  such
termination to take effect not sooner than seventy five (75) days after the date
of such delivery or mailing.  In the event of termination the Custodian shall be
entitled  to  receive  prior to  delivery  of the  securities,  funds  and other
property  held by it all accrued fees and  unreimbursed  expenses the payment of
which is  contemplated  by  Sections  6D and 7,  upon  receipt  by the Fund of a
statement setting forth such fees and expenses.

         In the event of the appointment of a successor custodian,  it is agreed
that the funds and securities owned by the Fund and held by the Custodian or any
Subcustodian  shall be delivered to the successor  custodian,  and the Custodian
agrees to cooperate  with the Fund in execution of documents and  performance of
other  actions  necessary  or  desirable in order to  substitute  the  successor
custodian for the Custodian under this Agreement.

         9. Amendment:  This Agreement  constitutes the entire understanding and
agreement of the parties hereto with respect to the subject  matter  hereof.  No
provision of this  Agreement may be amended or terminated  except by a statement
in writing  signed by the party  against which  enforcement  of the amendment or
termination is sought.

                                      -33-

the  Fund  may  agree  in  writing   from  time  to  time  on  such   provisions
interpretative  of or in addition to the  provisions of this Agreement as may in
their joint opinion be consistent with the general tenor of this  Agreement.  No
interpretative  or  additional  provisions  made as  provided  in the  preceding
sentence shall be deemed to be an amendment of this Agreement.

parties  and  in  no  way  alter,  amend,  limit  or  restrict  the  contractual
obligations of the parties set forth in this Agreement.

Commonwealth of Massachusetts  and shall be governed by and construed  according

                               CUSTODIAN AGREEMENT

         AGREEMENT made this _____ day of  ______________,  1993 between PIONEER
MASSACHUSETTS  DOUBLE TAX FREE 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:

         l.  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 

<PAGE>

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

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

provided  that the  instructions  relating to such  disposition  shall include a
statement  of the  purpose for which the  delivery is to be made,  the amount of

         W.  Investment  Limitations - In performing its duties  generally,  and
more  particularly  in  connection  with  the  purchase,  sale and  exchange  of
securities  made by or for the Fund,  the  Custodian may assume unless and until
notified in writing to the contrary that proper instructions  received by it are
not in  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 the Fund of any investment  limitations to which the Fund
is  subject or other  limitations  with  respect  to the  Fund's  powers to make
expenditures,  encumber securities, borrow or take similar actions affecting the
Fund.

         X. Restricted  Securities.  Notwithstanding any other provision of this
Agreement,  the Custodian  shall not be liable for failure to take any action in
respect of a "restricted  security" (as hereafter  defined) if the Custodian has
not received Proper  Instructions to take such action (including but not limited
to the  failure  to  exercise  in a timely  manner  any right in  respect of any
restricted  security) unless the Custodian's  responsibility to take 

                                      -17-
<PAGE>

such action is set forth in a writing, agreed upon by the Custodian and the Fund
or the investment  adviser of the Fund, which specifies  particular  actions the
Custodian is to take without Proper  Instructions in respect of specified rights
and obligations  pertaining to a particular  restricted  security.  Further, the
Custodian  shall not be responsible  for  transmitting  to the Fund  information
concerning a restricted  security,  such as with respect to exercise periods and
expiration  dates for rights  relating to the restricted  security,  except such
information  which the  Custodian  actually  receives or which is published in a
source which is publicly  distributed and generally recognized as a major source
of information  with respect to corporate  actions of securities  similar to the
particular restricted security. As used herein, the term "restricted securities"
shall mean securities which are subject to restrictions on transfer,  whether by
reason of contractual  restrictions or federal,  state or foreign  securities or
similar laws, or securities  which have special rights or  contractual  features
which do not  apply to  publicly  traded  shares  of,  or  comparable  interests
representing, such security.

                                      -18-
<PAGE>


         Y. Proper  Instructions - Proper instructions shall mean a tested telex
from the Fund or a written  request,  direction,  instruction  or  certification
signed or  initialled  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  be  signed  by such  person.  Those  persons  authorized  to give  proper
instructions  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 

                                      -19-
<PAGE>
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  electro-mechanical  or  electronic  devices or systems,  in addition to
tested telex,  provided that the Fund and the Custodian agree to the use of such
device or system.

         z.  Segregated  Account - The  Custodian  shall upon  receipt of proper
instructions  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 Commodity Futures Trading Commission or any
registered  contract  market),  or any similar  organization  or  


                                      -20-
<PAGE>

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  (l) 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

                                      -21-
<PAGE>

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 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  


                                      -22-
<PAGE>

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


                                      -23-
<PAGE>

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.

         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 

                                      -24-
<PAGE>

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.

         5.  Powers  and  Duties of the  Custodian  with  Respect to its Role as
Financial  Agent:  The Fund hereby also  appoints  the  Custodian  as the Fund's
financial  agent.  With  respect to the  appointment  as  financial  agent,  the
Custodian shall have and perform the following powers and duties:

         A. Records - To create,  maintain  and retain such records  relating to
its  activities and  obligations  under this Agreement as are required under the
Investment  Company  Act of  1940  and  the  rules  and  regulations  thereunder
(including  Section 31 thereof and 

                                      -25-
<PAGE>

Rules 31a-1 and 31a-2  thereunder)  and under  applicable  Federal and State tax
laws.  All such  records  will be the  property  of the Fund and in the event of
termination of this Agreement shall be delivered to the successor custodian.

         B. Accounts - To keep books of account and render statements, including
interim monthly and complete quarterly 
financial  statements,  or  copies  thereof,  from  time to  time as  reasonably
requested by proper instructions.

         C.  Access  to  Records  - The  books  and  records  maintained  by the
Custodian  pursuant  to  Sections  5A  and 5B  shall  at all  times  during  the
Custodian's  regular  business hours be open to inspection and audit by officers
of, attorneys for and auditors  employed by the Fund and by employees and agents
of the Securities and Exchange  Commission,  provided that all such  individuals
shall observe all security  requirements of the Custodian  applicable to its own
employees  having  access to  similar  records  within  the  Custodian  and such
regulations as may be reasonably imposed by the Custodian.

         D. Disbursements - Upon receipt of proper instructions, to pay or cause
to be paid,  insofar as funds are available for the purpose,  bills,  statements
and  other  obligations  of the Fund  (including  but not  limited  to  interest
charges,  taxes,  management fees,  compensation to Fund officers and employees,
and other operating expenses of the Fund).

<PAGE>

         6.       Standard of Care and Related Matters:

         A.  Liability of the  Custodian  with  Respect to Proper  Instructions;
Evidence of  Authority,  Etc. The  Custodian  shall not be liable for any action
taken or omitted in  reliance  upon  proper  instructions  believed  by it to be
genuine  or upon any other  written  notice,  request,  direction,  instruction,
certificate or other  instrument  believed by it to be genuine and signed by the
proper party or parties.

         The  Secretary or Assistant  Secretary of the Fund shall certify to the
Custodian the names, signatures and scope of authority of all persons authorized
to give  proper  instructions  or any other  such  notice,  request,  direction,
instruction,  certificate  or  instrument  on behalf of the Fund,  the names and
signatures of the officers of the Fund, the name and address of the  Shareholder
Servicing Agent, and any resolutions,  votes,  instructions or directions of the
Fund's Board of Directors or Trustees or  shareholders.  Such certificate may be
accepted and relied upon by the  Custodian as  conclusive  evidence of the facts
set forth  therein and may be  considered in full force and effect until receipt
of a similar certificate to the contrary.

         So long as and to the extent that it is in the  exercise of  reasonable
care,  the  Custodian  shall  not be  responsible  for the  title,  validity  or
genuineness  of any  property  or evidence  of 

                                      -27-
<PAGE>

title thereto received by it or delivered by it pursuant to this Agreement.

         The Custodian shall be entitled, at the expense of the Fund, to receive
and act upon  advice of (i)  counsel  regularly  retained  by the  Custodian  in
respect of custodian  matters,  (ii)  counsel for the Fund,  or (iii) such other
counsel  as the Fund and the  Custodian  may agree  upon,  with  respect  to all
matters,  and the Custodian shall be without liability for any action reasonably
taken or omitted pursuant to such advice.

         B. Liability of the Custodian with Respect to Use of Securities  System
- - With respect to the portfolio securities,  cash and other property of the Fund
held by a Securities  System, the Custodian shall be liable to the Fund only for
any loss or damage to the Fund resulting  from use of the  Securities  System if
caused by any  negligence,  misfeasance or misconduct of the Custodian or any of
its  agents  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.

                                      -28-
<PAGE>

         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  terms  set forth in the  subcustodian  agreement  between  the
Custodian  and the  Subcustodian  (or in the  subcustodian  agreement  between a
Subcustodian  and any secondary  Subcustodian),  the  Subcustodian (or secondary
Subcustodian)  has failed to perform in accordance  with the standard of conduct
imposed under such  subcustodian  agreement as determined in accordance with the
law which is  adjudicated  to govern such  agreement and in accordance  with any
determination  of any court as to the duties of said  Subcustodian  pursuant  to
said  agreement.  The  Custodian  shall  also be  liable to the Fund for its own
negligence in 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 all claims and  liabilities  (including  counsel fees) 


                                      -29-
<PAGE>

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 of the Fund is  registered  against any
liability the Custodian or such nominee 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  directly or  indirectly  from the fact
that  portfolio  securities  or other  property of the Fund is registered in the
name of the Custodian or such nominee.

         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


                                      -30-
<PAGE>

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 Fund,  including in connection  with foreign  exchange  contracts or options
(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 


                                      -31-
<PAGE>

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.

         H. Powers of  Attorney - Upon  request,  the Fund shall  deliver to the
Custodian  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 any  Subcustodian  of  their  respective  obligations  under  this
Agreement or any applicable subcustodian agreement.


                                      -32-
<PAGE>
         7.  Compensation  of the Custodian:  The Fund shall pay the Custodian a
custody  fee based on such fee  schedule as may from time to time be agreed upon
in writing by the  Custodian and the Fund.  Such fee,  together with all amounts
for which the Custodian is to be reimbursed in accordance with Section 6D, shall
be billed to the Fund in such a manner as to  permit  payment  by a direct  cash
payment to the Custodian.

         8. Termination;  Successor Custodian:  This Agreement shall continue in
full force and effect  until  terminated  by either  party by an  instrument  in
writing  delivered  or  mailed,  postage  prepaid,  to  the  other  party,  such
termination to take effect not sooner than seventy five (75) days after the date
of such delivery or mailing.  In the event of termination the Custodian shall be
entitled  to  receive  prior to  delivery  of the  securities,  funds  and other
property  held by it all accrued fees and  unreimbursed  expenses the payment of
which is  contemplated  by  Sections  6D and 7,  upon  receipt  by the Fund of a
statement setting forth such fees and expenses.

         In the event of the appointment of a successor custodian,  it is agreed
that the funds and securities owned by the Fund and held by the Custodian or any
Subcustodian  shall be delivered to the successor  custodian,  and the Custodian
agrees to cooperate  with the Fund in execution of documents and  performance of
other
                                      -33-
<PAGE>
actions  necessary or desirable in order to substitute  the successor  custodian
for the Custodian under this Agreement.

         9. Amendment:  This Agreement  constitutes the entire understanding and
agreement of the parties hereto with respect to the subject  matter  hereof.  No
provision of this  Agreement may be amended or terminated  except by a statement
in writing  signed by the party  against which  enforcement  of the amendment or
termination is sought.

         In connection with the operation of this  Agreement,  the Custodian and
the  Fund  may  agree  in  writing   from  time  to  time  on  such   provisions
interpretative  of or in addition to the  provisions of this Agreement as may in
their joint opinion be consistent with the general tenor of this  Agreement.  No
interpretative  or  additional  provisions  made as  provided  in the  preceding
sentence shall be deemed to be an amendment of this Agreement.

         The section  headings in this Agreement are for the  convenience of the
parties  and  in  no  way  alter,  amend,  limit  or  restrict  the  contractual
obligations of the parties set forth in this Agreement.

         10.  Governing  Law:  This  instrument is executed and delivered in The
Commonwealth of Massachusetts  and shall be governed by and construed  according
to the laws of said Commonwealth.

its rights or  obligations  hereunder  without the prior written  consent of the
other party.

         13.  Counterparts:  This  Agreement  may be  executed  in any number of
counterparts,  each of which shall be deemed an original.  This Agreement  shall

                      INVESTMENT COMPANY SERVICE AGREEMENT

                                February 19, 1993

         Pioneer  Tax-Free  State Series Trust, a  Massachusetts  business trust
with its principal place of business at 60 State Street,  Boston,  Massachusetts
02109  ("Customer")  and  Pioneering  Services   Corporation,   a  Massachusetts
corporation ("PSC"), hereby agree as follows:

         1. SERVICES TO BE PROVIDED BY PSC.  During the term of this  Agreement,
PSC will provide to each series of shares of beneficial  interest (the "Series")
of Customer, which may be established,  from time to time (the "Account"),  with
the services described in Exhibits A, B, C, and D (collectively, the "Exhibits")
that are attached hereto and incorporated herein by reference.  It is understood
that PSC may subcontract any of such services to one or more firms designated by
PSC,  provided  that PSC (i) shall be solely  responsible  for all  compensation
payable  to any such firm and (ii) shall be liable to  Customer  for the acts or
omissions of any such firm to the same extent as PSC would be liable to Customer
with respect to any such act or omission hereunder.

         2. EFFECTIVE DATE.  This Agreement  shall become  effective on the date
hereof  (the  "Effective  Date")  and  shall  continue  in  effect  until  it is
terminated in accordance with Section 11 below.

         3. DELIVERY, VERIFICATION AND RECEIPT FOR DATA AND ASSETS. Prior to the
Effective Date, Customer agrees to deliver to PSC all such  documentation,  data
and  materials  as PSC may  reasonably  prescribe  to enable it to  perform  the
services contemplated by this Agreement. If PSC so requests,  Customer agrees to
confirm the accuracy of any starting  records of Customer's  assets and accounts
produced from PSC's computer or held in other  recording  systems.  In the event
Customer  does not,  prior to the Effective  Date,  comply fully with any of the
foregoing  provisions  of this  Section  3, the date for  commencement  of PSC's
services  hereunder  may be  postponed  by PSC until such  compliance  has taken
place.

         Customer  shall,  from time to time,  while this Agreement is in effect
deliver all such  materials  and data as may be necessary or desirable to enable
PSC to perform its  services  hereunder,  including  without  limitation,  those
described in Section 12 hereof.

         4.  REPORTS  AND  MAINTENANCE  OF RECORDS BY PSC.  PSC will  furnish to
Customer and to properly authorized Auditors, examiners, distributors,  dealers,
underwriters, salesmen, insurance companies, investors, and others designated by
Customer in writing,  such books,  any and all records and reports at such 

<PAGE>

times as are  prescribed  for each  service  in the  Exhibits  attached  hereto.
Customer agrees to examine or to ask any other  authorized  recipient to examine
each such report or copy  promptly  and will report or cause to be reported  any
errors or  discrepancies  therein of which Customer then has any knowledge.  PSC
may at its option at any time, and shall forthwith upon Customer's demand,  turn
over to  Customer  and cease to retain in PSC's  files,  any and all records and
documents  created and maintained by PSC pursuant to this Agreement which are no
longer needed by PSC in the performance of its services or for its protection.

         If not so turned over to Customer,  such  documents and reports will be
retained  by PSC for six years from the year of the  creation,  during the first
two of which  the same will be in  readily  accessible  form.  At the end of six
years, such records and documents, will be turned over to Customer by PSC unless
Customer authorizes their destruction.

         5. PSC'S DUTY OF CARE.  PSC shall at all time use  reasonable  care and
act in good  faith in  performing  its  duties  hereunder.  PSC  shall  incur no
liability to Customer in connection with its  performance of services  hereunder
except to the extent that it does not comply with the foregoing standards.

         PSC  shall at all  times  adhere  to  various  procedures  and  systems
consistent  with  industry  standards in order to safeguard  Customer's  checks,
records and other data from loss or damage  attributable  to fire or theft.  PSC
shall maintain insurance adequate to protect against the costs of reconstructing
checks,  records  and other  data in the  event of such  loss and  shall  notify
Customer in the event of a material  adverse change in such insurance  coverage.
In the event of damage or loss occurring to Customer's records or data such that
PSC is unable  to meet the  terms of this  Agreement,  PSC  shall  transfer  all
records and data to a transfer  agent of  Customer's  choosing  upon  Customer's
written authorization to do so.

         Without  limiting the  generality  of the  foregoing,  PSC shall not be
liable or responsible for delays or errors  occurring by reason of circumstances
beyond its  control  including  acts of civil,  military  or banking  authority,
national  emergencies,  labor  difficulties,  fire, flood or other catastrophes,
acts of God, insurrection, war, riots, failure of transportation,  communication
or power supply.

         6.  CONFIDENTIALITY.   PSC  will  keep  confidential  all  records  and
information  provided by Customer or by the  shareholders of the Account to PSC,
except to the extent disclosures are required by this Agreement, are required by
the  Customer's  Prospectus  and  


                                      -2-
<PAGE>

Statement of  Additional  Information,  or are  required by a valid  subpoena or
warrant  issued by a court of  competent  jurisdiction  or by a state or federal
agency or governmental authority.

         7. CUSTOMER  INSPECTION.  Upon reasonable  notice, in writing signed by
Customer,  PSC shall make available,  during regular business hours, all records
and other data created and maintained  pursuant to this Agreement for reasonable
audit and  inspection by Customer or  Customer's  agents,  including  reasonable
visitation by Customer or Customer's agent, including inspecting PSC's operation
facilities.  PSC shall not be liable for injury to or responsible in any way for
the safety of any individual  visiting PSC's  facilities  under the authority of
this  section.   Customer  will  keep   confidential  and  will  cause  to  keep
confidential all confidential information obtained by its employees or agents or
any other individual representing Customer while on PSC's premises. Confidential
information shall include (1) any information of whatever nature regarding PSC's
operations, security procedures, and data processing capabilities, (2) financial
information  regarding  PSC,  its  affiliates,  or  subsidiaries,  and  (3)  any
information of whatever kind or  description  regarding any customer of PSC, its
affiliates or subsidiaries.

         8. RELIANCE BY PSC ON INSTRUCTIONS AND ADVICE;  INDEMNITY. PSC shall be
entitled  to seek  advice of  Customer's  legal  counsel  with  respect to PSC's
responsibilities  and  duties  hereunder  and  shall in no event  be  liable  to
Customer for any action taken pursuant to such advice, except to the extent that
Customer's legal counsel determines in its sole discretion that the rendering of
advice to PSC would result in a conflict of interest.

         Whenever PSC is authorized to take action hereunder  pursuant to proper
instructions from Customer,  PSC shall be entitled to rely upon any certificate,
letter or other  instrument or telephone call  reasonably  believed by PSC to be
genuine  and to have  been  properly  made or  signed  by an  officer  or  other
authorized  agent of  Customer,  and shall be entitled to receive as  conclusive
proof of any  fact or  matter  required  to be  ascertained  by it  hereunder  a
certificate  signed by an officer of Customer or any other person  authorized by
Customer's Board of Trustees.

         Subject to the  provisions  of Section 13 of this  Agreement,  Customer
agrees to indemnify and hold PSC, its  employees,  agents and nominees  harmless
from any and all claims,  demands,  actions  and suits,  whether  groundless  or
otherwise,  and from and against  any and all  judgments,  liabilities,  losses,
damages,  costs,  charges,  counsel fees and other  expenses of every 


                                      -3-
<PAGE>

nature and  character  arising out of or in any way  relating to PSC's action or
non-action  upon  information,  instructions or requests given or made to PSC by
Customer with respect to the Account.

         Notwithstanding the above,  whenever Customer may be asked to indemnify
or hold PSC harmless,  Customer shall be advised of all pertinent  facts arising
from the situation in question.  Additionally,  PSC will use reasonable  care to
identify and notify Customer  promptly  concerning any situation which presents,
actually or potentially, a claim for indemnification against Customer.  Customer
shall have the option to defend PSC  against any claim for which PSC is entitled
to  indemnification  from  Customer  under  the terms  hereof,  and in the event
Customer so elects, it will notify PSC and, thereupon,  Customer shall take over
complete  defense of the claim and PSC shall  sustain no further  legal or other
expenses  in such a  situation  for  which  indemnification  shall be  sought or
entitled.  PSC may in no event  confess any claim or make any  compromise in any
case in which  Customer  will be asked to indemnify  PSC except with  Customer's
prior written consent.

         9.  MAINTENANCE  OF DEPOSIT  ACCOUNTS.  PSC shall maintain on behalf of
Customer such deposit  accounts as are necessary or desirable  from time to time
to enable PSC to carry out the provisions of this Agreement.

         10. COMPENSATION AND REIMBURSEMENT TO PSC. For the services rendered by
PSC under  this  Agreement,  Customer  agrees to pay an annual fee of $21.95 per
account  to PSC,  such fee to be  payable  in  equal  monthly  installments.  In
addition,  Customer shall reimburse PSC monthly for out-of-pocket  expenses such
as postage, forms,  envelopes,  checks,  "outside" mailings,  telephone line and
other charges,  mailgrams,  mail insurance on  certificates  and data processing
file recovery insurance.

         11. TERMINATION.  Either PSC or Customer may at any time terminate this
Agreement by giving 90 days' prior written notice to the other.

         After the date of termination,  for so long as PSC in fact continues to
perform any one or more of the services  contemplated  by this  Agreement or any
exhibit hereto,  the provisions of this Agreement,  including without limitation
the provisions of Section 8 dealing with indemnification, shall where applicable
continue in full force and effect.

         12. REQUIRED DOCUMENTS.  Customer agrees to furnish to PSC prior to the
Effective Date the following (to the extent not previously provided):

interpretative  or  additional  provisions  are to be signed by both parties and
annexed hereto,  but no such provision shall  contravene any applicable  Federal

amendment of this Agreement.

         This  Agreement  shall be construed in accordance  with the laws of The
Commonwealth of Massachusetts.

         IN WITNESS  WHEREOF,  Customer and PSC have caused this Agreement to be
executed in their respective names by their respective  officers  thereunto duly
authorized as of the date first written above.

Trustees of Pioneer
  Tax-Free State Series Trust
60 State Street
Boston, Massachusetts  02109


Ladies and Gentlemen:

         We have been  informed  that Pioneer  Tax-Free  State Series Trust (the
"Trust")  proposes to register under the Securities Act of 1933, as amended (the
"Act"),  and to offer and sell from time to time, an indefinite number of shares
of beneficial interest,  without par value, of three of its series designated as
Pioneer  California Double Tax-Free Fund,  Pioneer New York Triple Tax-Free Fund
and Pioneer Massachusetts Double Tax-Free Fund (the "Funds"), which shares shall
be  sold  at not  less  than  "net  asset  value,"  as  defined  in the  Trust's
Declaration of Trust ("Fund Shares"). The Trustees of the Trust have established
the Funds pursuant to Article V, Section 5.1 of the Trust's Declaration of Trust
dated  November 6, 1992 and executed and delivered in Boston,  Massachusetts  on
that day (the "Declaration of Trust").

         We have examined the Trust's  Declaration  of Trust,  By-Laws,  Written
Actions of the Board of  Trustees,  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 such  documents,  we have assumed the genuineness
of  all  signatures,  the  authenticity  of  all  documents  submitted  to us as
originals, the conformity to original 

<PAGE>
Trustees of Pioneer
Tax-Free State Series Trust
January 28, 1993
Page 2



documents of all documents  submitted to us as certified or  photostatic  copies
and the authenticity of the originals of such latter documents.

         The  opinion  set  forth  in  paragraph  3 below is  qualified  in that
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  disclaims  shareholder  liability for  obligations of the
Trust and requires that notice of such disclaimer be given in every note,  bond,
contract, instrument,  certificate or undertaking made or issued by the Trustees
or by any officer or officers of the Trust.  The  Declaration  of Trust provides
for indemnification  against all loss and expense of any shareholder of a series
of Fund Shares held personally liable solely by reason of being or having been a
shareholder of a Fund, such  indemnification to be paid solely out of the assets
of such series.  Thus, the  shareholder's  risk is limited to  circumstances  in
which  the  assets  of the  particular  series  of  which  he or she is or was a
shareholder  would be insufficient to meet the obligations  asserted  against or
with respect to such assets.

         We have  not made an  independent  review  of the laws of any  state or
jurisdiction other than the laws of The Commonwealth of Massachusetts.

         Based on and subject to the foregoing, we are of the opinion that:

               1. The  Trust is duly  organized,  validly  existing  and in good
standing under the laws of The Commonwealth of Massachusetts; and

               2.  The  beneficial  interest  of the  Trust is  divided  into an
unlimited number of shares of beneficial interest, no par value per share.

               3.  The  Fund  Shares  will be  validly  issued,  fully  paid and
non-assessable by the Funds when issued in accordance with the provisions of the
Declaration of Trust and subject to compliance  with the Securities Act of 1933,
the Investment  Company Act of 1940 and the applicable state laws regulating the
sale of securities.

         We understand that the Trust is currently in the process of registering
or qualifying  shares of the Funds in various 

<PAGE>

states.  We hereby  consent  to the  filing of a copy of this  opinion  with the
securities  administrators  for such states and with the Securities and Exchange
Commission  as part of the Trust's  Registration  Statement  on Form N-1A (or an
amendment  thereto) covering an indefinite number of Fund Shares. We hereby also
consent  to  the   reference  to  our  firm  under  the   captions   "Dividends,
Distributions and  Taxation--Pioneer  Massachusetts Double Tax-Free Fund" in the
Funds'  Prospectus dated January 29, 1993 and  "Tax-Status--Massachusetts  State
and Local Tax Matters" in the Funds' Statement of Additional  Information  dated
January 29, 1993.  This opinion may not be filed with any other  parties or used
for any other purpose.

DOUBLE TAX-FREE 
FUND 

ANNUAL REPORT 
SEPTEMBER 30, 1995 

DEAR SHAREOWNER, 

Pioneer  Massachusetts  Double  Tax-Free Fund completed its third fiscal year on
September 30, 1995. This report details the favorable  environment for municipal
bond investing during the period, and highlights your Fund's impressive results.
In fact, the Fund's total return for the year ended  September 30, 1995, was the
highest  among all 44  Massachusetts  municipal  debt  funds  tracked  by Lipper
Analytical  Services,  an  independent  mutual  fund  research  firm.1  While we
encourage you to look at the Fund as a long-term investment, we are pleased with
its recent shorter-term results.

                          HOW YOUR FUND PERFORMED 

We report the following for Pioneer Massachusetts Double Tax-Free Fund as of 
September 30, 1995: 

* A tax-free 30-day yield of 4.80%.2 

  Your Fund's  tax-free  yield was equivalent to a taxable yield of 9.03% at the
  end  of  the  period,  based  on  the  46.85%  maximum  combined  federal  and
  Massachusetts personal income tax rate.

* Shareowners received tax-exempt dividends totaling $0.546 per share for the 
  year. 

* Net asset value stood at $10.98 per share, versus $10.29 one year earlier. 

* The Fund's total return for the year ended 
  September 30 was 12.36% based on net asset value, and 8.46% based on public 
  offering price. Total return represents the change in share price and assumes 
  reinvestment of all distributions at net asset value.

                     BOND PRICES ROSE DURING THE YEAR 

Over the past year,  the Federal  Reserve (the Fed) raised  short-term  interest
rates twice,  on November 15 and February 1,  bringing the federal funds rate as
high as 6.0% and triggering  periods of falling bond prices.  The Fed's decision
to raise rates was based on its fear of too-fast  economic growth and inflation.
Investors,  also  uncertain  about  these  matters,  added to the bond  market's
turmoil, fueling its poor performance in 1994.

Moving into 1995,  however,  the Fed's efforts began to have the desired effect;
many economic indicators slowed, and inflation remained low. Even the Fed's rate
hike on February 1 did little to temper the bond market's positive momentum;  if
anything,  many  investors  saw  the  increase  as an  indication  of the  Fed's
determination  to keep the economy  from  expanding  too  quickly.  In fact,  in
response  to ongoing  signs of slowing  economic  growth,  the Fed  lowered  the
federal  funds rate to 5.75% on July 6. This  action  pushed many bond prices to
some of the highest levels of the year. While various events  temporarily caused
prices  to fall,  conditions  over  the past 12  months  were  favorable  -- and
rewarding -- for bond investors.

Municipal investors in particular  benefited over the year, thanks in large part
to the record low supply of securities made available in 1994 and 1995, combined
with the $35  billion of  municipal  securities  retired  on July 1.  Demand for
short- term municipal bonds increased as the period progressed, while demand for
long- term  municipal  bonds  fell.  This shift in demand was spurred by ongoing
discussions of tax reform;  because of the uncertainty  surrounding the type and
timing of tax reform,  investors  are demanding  higher yields on  long-maturity
bonds to offset their heightened risk. As a result, short-maturity issues became
"rich" toward the end of the period, relative to Treasury securities, while long
maturities became "cheap."

                    HOW PIONEER MANAGED YOUR INVESTMENT 

Your Fund's portfolio  holdings had an average quality rating of AA on September
30,  1995.  This  high-quality  focus  should  provide  a level  of  comfort  to
conservative  investors  uncomfortable with bonds rated below  investment-grade.
Your  Fund's   management  does  not  invest  in  lower-quality   securities  or
speculative investments.  The Fund also avoids issues subject to the alternative
minimum tax (AMT).

                             PORTFOLIO QUALITY 
                        (as of September 30, 1995) 

                    Cash and Cash Equivalents 2% 
                                           A 45% 
                                          AA 13% 
                                         AAA 40%

  does not guarantee future results. 

2 Based  on a  standard  formula  prescribed  by  the  Securities  and  Exchange
  Commission. The Fund's investment manager,  Pioneering Management Corporation,
  currently is reducing its management fee and certain other expenses, otherwise
  the Fund's  total  return  would have been lower and the yield would have been
  2.52%. 
<PAGE>
                                   
Your  management  reduced the Fund's  exposure to  long-maturity  bonds over the
quarter.  Given  the  ongoing  debate  about  tax  reform,  and  flat  taxes  in
particular,  we think a more  conservative  position will be most  successful in
maintaining the Fund's share price and income stream.  By the end of the period,
the Fund's holdings had an average  effective life of 13 years,  versus 17 years
on September 30, 1994.  We reduced the Fund's  weighting in bonds with more than
10 years to maturity to 64% of the portfolio,  versus 94% one year ago. Instead,
we  significantly  increased  the number of  intermediate-term  holdings to take
advantage of their  greater  liquidity  and share price  stability.  We made the
largest  increase  in  the  seven-to-10-year  range,  which  totaled  31% of the
portfolio on September 30, versus 4% one year ago.

                            PORTFOLIO MATURITY 
                        (as of September 30, 1995) 

                                   0-7 Years  5% 
                                  7-10 Years 31% 
                                 10-20 Years 52% 
                                   20+ Years 12% 

The Fund remains  diversified across market sectors within the Commonwealth.  We
continue to favor securities that finance essential  services,  as well as those
with an income  stream that is  dedicated  to the  repayment  of  principal  and
interest.  Our approach inevitably leads to high-quality  investments in revenue
bonds sold to finance schools, roads and water/sewer facilities. As of September
30, 21% of the  portfolio  was invested in bonds issued by  prestigious  private
schools and universities. The fiscal well-being of these establishments tends to
come from large endowments and independent financial resources,  as well as high
demand,  and does not rely on the Commonwealth's  economy.  At the period's end,
your Fund also had 12% of its portfolio in transportation bonds. Issuers such as
Massachusetts Port Authority, Massachusetts Turnpike Authority and Massachusetts
Bay Transit Authority use tolls and user fees to ensure payment on their issues,
and have a solid track record for repaying their debt.

                               LOOKING AHEAD 

After a slow start to the fiscal year, improving conditions -- low inflation,  a
moderately  paced economy and  favorable  interest  rates -- have  significantly
lifted the bond market.  In fact,  these  conditions  have enabled  investors to
erase  1994's  losses and enjoy  rising  bond  prices.  While the past two years
remind us that  investing can be volatile,  they also  illustrate the benefit of
maintaining a longer-term horizon and considering  temporary downturns as buying
opportunities.

As we move into your Fund's  fourth  fiscal  year,  we will  continue to monitor
events affecting the bond market,  including changes in interest rates, economic
data and the strength of the U.S. dollar. For the municipal bond market, we will
closely watch political debates about the national  deficit,  new federal budget
and tax  reform.  The  impact  on  municipal  bonds  will  depend on a number of
factors, including the rates at which unearned income is taxed, which deductions
are  eliminated,  the percentage of taxpayers  subject to each rate, and whether
additional  restrictions  are placed on municipal bond  issuance.  We expect the
national  debate to heat up as specific  tax-reform  proposals are put forth and
opponents formulate responses.

Even with tax reform,  your  management is confident that  municipal  bonds will
continue to play a significant role for investors, especially given their recent
value and limited  supply.  In  addition,  the Fund's  conservative  positioning
should be effective in minimizing the effects of interest rate changes and other
external  events.  We believe  our  strategy  will offer  shareowners  rewarding
performance and a high level of comfort.

financial statements as of September 30, 1995. If you have any questions about 
your investment in Pioneer Massachusetts Double Tax-Free Fund, please contact

The Lehman Brothers Municipal Bond Index is an unmanaged, composite measure 
of investment-grade municipal bonds. Index returns assume reinvestment of 
dividends, but, unlike Fund returns, do not reflect any fees, expenses or sales 
charges. Investors cannot invest directly in the Index. 

Past  performance  does not  guarantee  future  results.  Return  and  principal
fluctuate,  and your shares, when redeemed, may be worth more or less than their
original  cost.  A portion of income  may be  subject to state and local  taxes,
although the Fund intends to minimize any taxable income. 3

     1. Pioneer  Massachusetts  Double  Tax-Free  Fund (the Fund),  one of three
funds  that  currently  composes  Pioneer  Tax-Free  State  Series  Trust,  is a
Massachusetts business trust registered under the Investment Company Act of 1940
as a non-diversified,  open-end  management  investment company. As of September
30,  1995,  The  Pioneer  Group,   Inc.  (PGI)  was  the  beneficial   owner  of
approximately  54% of the  outstanding  shares of the Fund.  The  following is a
summary of significant  accounting policies  consistently  followed by the Fund,
which are in conformity with those generally  accepted in the investment company
industry.

    A. Security Valuation -- Security transactions are recorded on trade date. 
Securities are valued based on valuations furnished by an independent pricing 
service that utilizes a matrix system. This matrix system reflects such factors 
as security prices, yields, maturities and ratings and is supplemented by dealer
and exchange quotations and fair market value information from other sources, 
as required. Market discount and premium are accreted or amortized daily on 
a straight-line basis. Original issue discount is accreted daily to interest 
income on a yield-to-maturity basis. Temporary cash investments are valued at 
amortized cost plus accrued interest, which approximates value. Interest income 
is recorded on the accrual basis. 

    Gains and losses on sales of investments are calculated on the "identified 
cost" method for both financial reporting and federal income tax purposes. It 
is the Fund's practice to first select for sale those securities that have the 
highest cost and also qualify for long-term capital gain or loss treatment for 
tax purposes. 

    B. Federal Taxes -- It is the Fund's policy to comply with the requirements 
of the Internal Revenue Code applicable to regulated investment companies and 
to distribute all of its taxable income and net realized capital gains, if any, 
to its shareholders. Therefore, no federal income tax provision is required. 

    The   characterization   of  distributions  to  shareholders  for  financial
reporting  purposes is determined in accordance  with federal  income tax rules.
Therefore,  the  source  of  the  Fund's  distributions  may  be  shown  in  the
accompanying  financial statements as either from or in excess of net investment
income or net realized gain on investment transactions, or from paid-in capital,
depending on the type of book/tax differences that may exist.

    C.  Trust  Shares -- The Fund  records  sales and  repurchases  of its trust
shares on trade date.  Shares are sold and redeemed on a continuous basis at net
asset value per share.  Net losses,  if any,  as a result of  cancellations  are
absorbed by Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for
the Fund and an indirect  subsidiary of PGI. PFD earned  $2,289 in  underwriting
commissions  on the sale of the  Fund's  trust  shares  during  the  year  ended
September 30, 1995. The Fund declares as daily  dividends  substantially  all of
its net  investment  income.  All dividends are paid on the last business day of
the month.  Short-term capital gain distributions,  if any, may be paid with the
daily dividends.

    2. Pioneering Management Corporation (PMC), the Fund's investment adviser, 
manages the Fund's portfolio and is a wholly owned subsidiary of PGI. Management
fees are calculated daily at the annual rate of 0.60% of the Fund's average 
daily net assets. 

    PMC has agreed not to impose a portion of its management  fees and to assume
other  operating  expenses  for the Fund to the  extent  necessary  to limit the
Fund's  expenses  to an annual  rate of 0.50% of the  Fund's  average  daily net
assets up to $20  million;  0.55% of the next $5  million;  0.60% of the next $5
million;  0.65% of the next $5 million;  0.70% of the next $5 million; and 0.75%
of the excess over $40 million.  PMC's  agreement is temporary and voluntary and
may be revised or terminated at any time.

    In addition, under the management agreement, certain other services and 
costs, including accounting, regulatory reporting and insurance premiums, are 
paid by the Fund. Included in Accrued expenses is $5,555 in accounting fees 
payable to PMC at September 30, 1995. 

    3. Pioneering Services Corporation (PSC), a wholly owned subsidiary of PGI, 
provides substantially all transfer agent and shareholder services to the Fund 
at negotiated rates. Included in Accrued expenses is $1,649 in transfer agent 
fees payable to PSC at September 30, 1995. 

    4. The Fund  adopted a Plan of  Distribution  (the Plan) that allows for the
Fund to  reimburse  PFD for  expenditures  to finance any  activities  primarily
intended  to  result  in the  sale  of  trust  shares.  The  Plan  provides  for
reimbursement  of such  expenditures  in an amount  not to  exceed  0.25% of the
Fund's  average  daily net assets.  In  addition,  a service fee of 0.15% of the
Fund's daily net assets is accrued daily and paid quarterly. Included in Accrued
expenses is $2,712 in distribution fees payable to PFD at September 30, 1995.

PIONEER 
NEW YORK 
TRIPLE TAX-FREE 
FUND 



ANNUAL REPORT 
SEPTEMBER 30, 1995 

DEAR SHAREOWNER, 

     Pioneer New York Triple  Tax-Free  Fund  completed its third fiscal year on
September 30, 1995. This report details the favorable  environment for municipal
bond investing during the period,  and highlights the impressive  performance of
your Fund.

                          HOW YOUR FUND PERFORMED 

We are pleased to report the following for Pioneer New York Triple Tax-Free 
Fund as of September 30, 1995: 

* Your Fund ranked in the top 7% of all New York tax- free income funds for 
  the year ended September 30, 1995, according to Lipper Analytical Services, 
  an independent mutual fund research firm.1 

* The Fund's total return for the year was 11.04% based on net asset value, 
  and 7.12% based on public offering price. Total return represents the change 
  in share price and assumes reinvestment of all distributions at net asset 
  value. 

* Net asset value stood at $10.96 per share, versus $10.39 one year earlier. 

* Shareowners received tax-exempt dividends totaling $0.543 per share. 

* The Fund's tax-free 30-day yield on September 30 was 4.68%.2 

Your Fund's tax-free yield was equivalent to a taxable yield of 8.81% at the 
end of the period, based on the 46.88% maximum combined federal, New York State 
and New York City personal income tax rate. 

For additional performance information, please turn to page 3. 

                     BOND PRICES ROSE DURING THE YEAR 

     Over the past  year,  the  Federal  Reserve  (the  Fed)  raised  short-term
interest rates twice,  on November 15 and February 1, bringing the federal funds
rate as high as 6% and  triggering  periods of falling  bond  prices.  The Fed's
decision to raise rates was based on its fear of  too-fast  economic  growth and
inflation.  Investors,  also uncertain  about these  matters,  added to the bond
market's turmoil, fueling its poor performance in 1994.

     Moving  into 1995,  however,  the Fed's  efforts  began to have the desired
effect;  many economic  indicators  slowed, and inflation remained low. Even the
Fed's rate hike on February 1 did little to temper the positive  momentum in the
bond market;  if anything,  many  investors saw the increase as an indication of
the Fed's determination to keep the economy from expanding too quickly. In fact,
in response to ongoing  signs of slowing  economic  growth,  the Fed lowered the
federal  funds rate to 5.75% on July 6. This  action  pushed many bond prices to
some of the highest levels of the year. While various events  temporarily caused
prices  to fall,  conditions  over  the past 12  months  were  favorable  -- and
rewarding -- for bond investors.

     Municipal investors in particular  benefited over the year, thanks in large
part to the record low supply of  securities  made  available  in 1994 and 1995,
combined with the $35 billion of municipal  securities retired on July 1. Demand
for short-term municipal bonds increased as the period progressed,  while demand
for  long-term   municipal  bonds  fell.  This  shift  was  spurred  by  ongoing
discussions of tax reform;  because of the uncertainty  surrounding the type and
timing of tax reform,  investors  are demanding  higher yields on  long-maturity
bonds to offset their heightened risk. As a result, short-maturity issues became
"rich" toward the end of the period, relative to Treasury securities, while long
maturities became "cheap."

                    HOW PIONEER MANAGED YOUR INVESTMENT 

     Your  Fund's  portfolio  holdings  had an average  quality  rating of AA on
September 30, 1995. This high-quality focus should provide a level of comfort to
conservative  investors  uncomfortable with bonds below  investment-grade.  Your
Fund does not invest in lower-quality securities or speculative investments. The
Fund also avoids issues subject to the alternative minimum tax (AMT).

                             PORTFOLIO QUALITY 
                        (as of September 30, 1995) 

                        Cash and Cash Equivalents 1% 
                                                A 32% 
                                               AA 28% 
                                              AAA 39% 

Your management reduced the Fund's exposure to long-maturity bonds over the 
year. Given the ongoing debate about tax reform, and flat taxes in particular, 
we 

1 The Fund ranked fifth of 79 funds; the ranking was based on total return and 
  does not account for sales charges or fee waivers. Past performance does not 
  guarantee future results. 

2 Based  on a  standard  formula  prescribed  by  the  Securities  and  Exchange
  Commission. The Fund's investment manager,  Pioneering Management Corporation,
  currently is reducing its management fee and certain other expenses, otherwise
  the Fund's  total  return  would have been lower and the yield would have been
  2.28%.

<PAGE> 

think a more  conservative  position will be most  successful in maintaining the
Fund's  share  price and income  stream.  By the end of the  period,  the Fund's
holdings had an average effective life of just over 11 years, versus 16 years on
September 30, 1994.  We reduced the Fund's  weighting in bonds with more than 10
years to maturity to 62% of the portfolio,  versus 93% one year ago. Instead, we
significantly  increased  the  number  of  intermediate-term  holdings,  to take
advantage of their  greater  liquidity  and share price  stability.  We made the
largest increase in the  seven-to-10-year  maturity range,  which totaled 27% of
the portfolio on September 30, versus 5% one year ago.

                            PORTFOLIO MATURITY 
                        (as of September 30, 1995) 

                           0-7   Years  11% 
                           7-10  Years  27%
                          10-20  Years  54%
                             20+ Years  8 %

     
The economic recovery in New York has been slow- moving.  In addition,  New York
City's credit rating was downgraded in July,  reflecting  ongoing  concern about
the City's  ability  to repay its debt in a timely  manner.  On a more  positive
note,  Governor George Pataki's deficit- reduction budget,  designed to help the
State's  stagnant  economy  rebuild,  has been  viewed by many  corporations  as
positive and conducive to business  operations.  Whether the budget is effective
in improving the economy over the long term,  however,  remains to be seen. Your
management   will  monitor  this   situation,   as  well  as  the  progress  and
effectiveness of other initiatives set forth by the State's administration.

Your Fund remains  well-diversified  across many market  sectors within New York
State.  Over the course of the year,  however,  we moved away from issues of New
York City,  given its economic and credit  concerns.  To safeguard the Fund from
such  credit  problems,  we  kept a  significant  portion  of the  portfolio  in
high-quality,  insured  bonds.  We continue  to favor  securities  that  finance
essential services,  as well as those with an income stream that is dedicated to
the repayment of principal and interest.  As a result,  on September 30 the Fund
held a number of bonds of private educational institutions, as well as providers
of essential  services  such as roads.  The  performance  of these  high-quality
securities tends not to be directly tied to the State's economy,  which we think
is most beneficial for your Fund at this point in time.

                               LOOKING AHEAD 

After a slow start to the fiscal year, improving conditions -- low inflation,  a
moderately  paced economy and  favorable  interest  rates -- have  significantly
lifted the bond market. In fact, these conditions have enabled investors to more
than erase 1994's losses.  While the past two years remind us that investing can
be volatile,  they also  illustrate  the benefit of  maintaining  a longer- term
horizon and considering temporary downturns as buying opportunities.

As we move into your Fund's  fourth  fiscal  year,  we will  continue to monitor
events affecting the bond market,  including changes in interest rates, economic
data and the strength of the U.S. dollar. For the municipal bond market, we will
closely watch political debates about the national  deficit,  new federal budget
and tax  reform.  The  impact  on  municipal  bonds  will  depend on a number of
factors,  including  the  rates at  which  investment  income  is  taxed,  which
deductions are eliminated, the percentage of taxpayers subject to each rate, and
whether additional restrictions are placed on municipal bond issuance. We expect
the national  debate to heat up as specific  tax-reform  proposals are put forth
and opponents formulate responses.

Even with tax reform,  your  management is confident that  municipal  bonds will
continue to play a significant role for investors, especially given their recent
value and limited  supply.  In  addition,  the Fund's  conservative  positioning
should be effective in minimizing the effects of interest rate changes and other
external  events.  We believe  our  strategy  will offer  shareowners  rewarding
performance and a high level of comfort.

The following pages provide details about your Fund, as well as its audited list
of portfolio holdings and financial  statements as of September 30, 1995. If you
have any questions  about your  investment  in Pioneer New York Triple  Tax-Free
Fund,  please  contact  your  investment  representative,  or  call  Pioneer  at

The Lehman Brothers Municipal Bond Index is an unmanaged, composite measure 
of investment-grade municipal bonds. The Index's returns assume reinvestment 
of dividends, but, unlike the Fund's returns, do not reflect any fees, expenses 
or sales charges. Investors cannot invest directly in the Index. 

Past  performance  does not  guarantee  future  results.  Return  and  principal
fluctuate,  and your shares, when redeemed, may be worth more or less than their
original  cost.  A portion of income  may be  subject to state and local  taxes,
although the Fund intends to minimize any taxable income.

NOTES TO FINANCIAL STATEMENTS -- SEPTEMBER 30, 1995 

     1.  Pioneer New York Triple  Tax-Free  Fund (the Fund),  one of three funds
that currently composes Pioneer Tax- Free State Series Trust, is a Massachusetts
business  trust  registered  under  the  Investment  Company  Act of  1940  as a
non-diversified,  open-end  management  investment  company. As of September 30,
1995, The Pioneer Group,  Inc. (PGI) was the beneficial  owner of  approximately
41% of the  outstanding  shares  of the Fund.  The  following  is a  summary  of
significant  accounting policies consistently followed by the Fund, which are in
conformity with those generally accepted in the investment company industry.

    A. Security  Valuation -- Security  transactions are recorded on trade date.
Securities are valued based on valuations  furnished by an  independent  pricing
service that utilizes a matrix system.  This matrix system reflects such factors
as security prices, yields, maturities and ratings and is supplemented by dealer
and exchange quotations and fair market value information from other sources, as
required.  Market  discount  and premium are  accreted or  amortized  daily on a
straight-line  basis.  Original  issue  discount is  accreted  daily to interest
income on a yield-to-  maturity basis.  Temporary cash investments are valued at
amortized cost plus accrued interest,  which approximates value. Interest income
is recorded on the accrual basis.

    Gains and losses on sales of investments are calculated on the "identified 
cost" method for both financial reporting and federal income tax purposes. It 
is the Fund's practice to first select for sale those securities that have the 
highest cost and also qualify for long-term capital gain or loss treatment for 
tax purposes. 

    B. Federal Taxes -- It is the Fund's policy to comply with the requirements 
of the Internal Revenue Code applicable to regulated investment companies and 
to distribute all of its taxable income and net realized capital gains, if any, 
to its shareholders. Therefore, no federal income tax provision is required. 

     The   characterization  of  distributions  to  shareholders  for  financial
reporting  purposes is determined in accordance  with federal  income tax rules.
Therefore,  the  source  of  the  Fund's  distributions  may  be  shown  in  the
accompanying  financial statements as either from or in excess of net investment
income or net realized gain on investment transactions, or from paid-in capital,
depending on the type of book/tax differences that may exist.

     C. Trust  Shares -- The Fund  records  sales and  repurchases  of its trust
shares on trade date.  Shares are sold and redeemed on a continuous basis at net
asset value per share.  Net losses,  if any,  as a result of  cancellations  are
absorbed by Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for
the Fund and an indirect  subsidiary of PGI. PFD earned  $2,927 in  underwriting
commissions  on the sale of the  Fund's  trust  shares  during  the  year  ended
September 30, 1995. The Fund declares as daily  dividends  substantially  all of
its net  investment  income.  All dividends are paid on the last business day of
the month.  Short-term capital gain distributions,  if any, may be paid with the
daily dividends.

    2. Pioneering  Management  Corporation (PMC), the Fund's investment adviser,
manages the Fund's portfolio and is a wholly owned subsidiary of PGI. Management
fees are  calculated  daily at the annual  rate of 0.60% of the  Fund's  average
daily net assets.

     PMC has agreed not to impose a portion of its management fees and to assume
other  operating  expenses  for the Fund to the  extent  necessary  to limit the
Fund's  expenses  to an annual  rate of 0.50% of the  Fund's  average  daily net
assets up to $20  million;  0.55% of the next $5  million;  0.60% of the next $5
million;  0.65% of the next $5 million;  0.70% of the next $5 million; and 0.75%
of the excess over $40 million.  PMC's  agreement is temporary and voluntary and
may be revised or terminated at any time.

    In addition, under the management agreement, certain other services and 
costs, including accounting, regulatory reporting and insurance premiums, are 
paid by the Fund. Included in Accrued expenses is $4,458 in accounting fees 
payable to PMC at September 30, 1995. 

    3. Pioneering Services Corporation (PSC), a wholly owned subsidiary of PGI, 
provides substantially all transfer agent and shareholder services to the Fund 
at negotiated rates. Included in Accrued expenses is $808 in transfer agent 
fees payable to PSC at September 30, 1995. 

     4. The Fund adopted a Plan of  Distribution  (the Plan) that allows for the
Fund to  reimburse  PFD for  expenditures  to finance any  activities  primarily
intended  to  result  in the  sale  of  trust  shares.  The  Plan  provides  for
reimbursement  of such  expenditures  in an amount  not to  exceed  0.25% of the
Fund's  average  daily net assets.  In  addition,  a service fee of 0.15% of the
Fund's daily net assets is accrued daily and paid quarterly. Included in Accrued
expenses is $1,732 in  distribution  fees payable to PFD at September  30, 1995.

reasonable  assurance  about  whether the  financial  statements  and  financial

test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements.  Our  procedures  included  confirmation  of securities  owned as of

CALIFORNIA 
DOUBLE TAX-FREE 
FUND 

ANNUAL REPORT 
SEPTEMBER 30, 1995 

DEAR SHAREOWNER, 

     Pioneer  California Double Tax-Free Fund completed its third fiscal year on
September 30, 1995. This report details the favorable  environment for municipal
bond investing during the period,  and highlights the impressive  results turned
in by your Fund.

                          HOW YOUR FUND PERFORMED 

We are pleased to report the following for Pioneer California Double Tax-Free 
Fund as of September 30, 1995: 

* Your Fund ranked in the top 7% of all California tax- free income funds for 
  the year ended September 30, 1995, according to Lipper Analytical Services, 
  an independent mutual fund research firm.1 

* The Fund's total return for the year ended  September 30 was 11.50% based
  on net asset value,  and 7.61% based on public  offering  price.  Total return
  represents  the  change  in  share  price  and  assumes  reinvestment  of  all
  distributions at net asset value.

* Net asset value stood at $10.81 per share, versus $10.22 one year earlier. 

* Shareowners received tax-exempt dividends totaling $0.55 per share. 

* The Fund's tax-free 30-day yield on September 30 was 4.97%.2 
  Your Fund's tax-free yield was equivalent to a taxable yield of 9.24% at the 
  end of the period, based on the 46.24% maximum combined federal and 
  California personal income tax rate. 

For additional performance information, please turn to page 4. 

                     BOND PRICES ROSE DURING THE YEAR 

     Over the past  year,  the  Federal  Reserve  (the  Fed)  raised  short-term
interest rates twice,  on November 15 and February 1, bringing the federal funds
rate as high as 6.0% and  triggering  periods of falling bond prices.  The Fed's
decision to raise rates was based on its fear of  too-fast  economic  growth and
inflation.  Investors,  also uncertain  about these  matters,  added to the bond
market's turmoil, fueling its poor performance in 1994.

Moving into 1995,  however,  the Fed's efforts began to have the desired effect;
many economic indicators slowed, and inflation remained low. Even the Fed's rate
hike on  February  1 did  little to temper  the  positive  momentum  in the bond
market;  if anything,  many  investors  saw the increase as an indication of the
Fed's  determination to keep the economy from expanding too quickly. In fact, in
response  to ongoing  signs of slowing  economic  growth,  the Fed  lowered  the
federal  funds rate to 5.75% on July 6. This  action  pushed many bond prices to
some of the highest levels of the year. While various events  temporarily caused
prices  to fall,  conditions  over  the past 12  months  were  favorable  -- and
rewarding -- for bond investors.

Municipal investors in particular  benefited over the year, thanks in large part
to the record low supply of securities made available in 1994 and 1995, combined
with the $35  billion of  municipal  securities  retired  on July 1.  Demand for
short-term municipal bonds increased as the period progressed,  while demand for
long-term  municipal  bonds  fell.  This shift in demand was  spurred by ongoing
discussions of tax reform;  because of the uncertainty  surrounding the type and
timing of tax reform,  investors are demanding  higher yields on long-  maturity
bonds to offset their heightened risk. As a result, short-maturity issues became
"rich" toward the end of the period, relative to Treasury securities, while long
maturities became "cheap."

                    HOW PIONEER MANAGED YOUR INVESTMENT 

Your Fund's portfolio  holdings had an average quality rating of AA on September
30,  1995.  This  high-quality  focus  should  provide  a level  of  comfort  to
conservative investors uneasy with bonds rated below investment-grade. Your Fund
does not invest in lower-quality securities or speculative investments. The Fund
also avoids issues subject to the alternative minimum tax (AMT).

                             PORTFOLIO QUALITY 
                        (as of September 30, 1995) 

                   Cash and Cash Equivalents  1% 
                                           A 22% 
                                          AA 43% 
                                         AAA 34% 


1 The Fund ranked  sixth of 92 funds;  the ranking was based on total return and
  does not account for sales charges or fee waivers.  Past  performance does not
  guarantee  future  results.  
2 Based  on a  standard  formula  prescribed  by  the  Securities  and  Exchange
  Commission. The Fund's investment manager,  Pioneering Management Corporation,
  currently is reducing its management fee and certain other expenses, otherwise
  the Fund's  total  return  would have been lower and the yield would have been
  3.19%.

 

Your  management  reduced the Fund's  exposure to  long-maturity  bonds over the
year.  Given the ongoing debate about tax reform,  and flat taxes in particular,
we think a more conservative position will be most successful in maintaining the
Fund's  share  price and income  stream.  By the end of the  period,  the Fund's
holdings had an average effective life of 16 years, versus 19 years on September
30,  1994.  We reduced the Fund's  weighting in bonds with more than 10 years to
maturity to 80% of the portfolio, versus 94% one year ago. Instead, we increased
the  number  of   intermediate-term   holdings,   specifically,   bonds  in  the
seven-to-10-year  maturity range,  to take advantage of their greater  liquidity
and share price  stability.  On September 30, 1995,  these issues totaled 14% of
the portfolio, versus zero one year ago.

                            PORTFOLIO MATURITY 
                        (as of September 30, 1995) 

                             0-7 Years  6% 
                            7-10 Years 14% 
                           10-20 Years 49% 
                             20+ Years 31% 

The Fund remains  diversified across many market sectors within  California.  Of
course,  just as  important as what the Fund's  portfolio  holds is what it does
not.  Specifically,  your  management  avoids  investments in hospital and lease
bonds, as well as certificates of  participation.  In our opinion,  these issues
put investors at risk since the repayment of principal and interest comes from a
third party,  not the issuing  municipality.  Instead,  we favor securities that
finance essential  services,  as well as those whose performance is not directly
tied  to  the  State's  troubled  economy.  Our  approach  inevitably  leads  to
high-quality  investments  in revenue  bonds sold to finance water and sewer and
power  facilities.  On September 30, your  portfolio had 21% of its portfolio in
water and sewer bonds, and another 14% in utility issues.

Orange County's fiscal troubles made some progress as the year  progressed.  The
County  declared  bankruptcy on December 6, 1994,  after a series of speculative
investments led to significant  losses in its investment pool. After a series of
debates and  proposals,  investors  in the pool agreed to a bailout plan whereby
money from other Orange  County  investments  would  contribute  and pay for the
defunct issues. On September 15, State legislators  approved this recovery plan;
Moody's  Investors  Service (a bond rating agency) responded a few days later to
legislative  actions by announcing it would review and  re-evaluate the County's
credit standing. We will continue to monitor this situation as it evolves.

Your Fund does not own any direct  obligations of Orange  County.  The portfolio
did contain Orange County Local Transportation Authority Sales Tax Revenue Bonds
and  South  Coast  Water  District   Revenue  Bonds,  two  securities  that  had
investments  in the pool managed by Orange County.  While the County's  problems
did not  affect  the  performance  of these  specific  bonds -- they made  their
scheduled  payments and maintained  their high quality ratings -- we nonetheless
took advantage of a market rally to sell them since they were not insured.

                               LOOKING AHEAD 

After a slow start to the fiscal year, improving conditions -- low inflation,  a
moderately  paced economy and  favorable  interest  rates -- have  significantly
lifted the bond market.  In fact,  these  conditions  have enabled  investors to
erase 1994's losses and to benefit from higher prices.  While the past two years
remind us that investing can be volatile,  they also illustrate the advantage of
maintaining a longer-term horizon and considering  temporary downturns as buying
opportunities.

As we move into your Fund's  fourth  fiscal  year,  we will  continue to monitor
events affecting the bond market,  including changes in interest rates, economic
data and the strength of the U.S. dollar. For the municipal bond market, we will
closely watch political debates about the national  deficit,  new federal budget
and tax  reform.  The  impact  on  municipal  bonds  will  depend on a number of
factors,  including  the  rates at  which  investment  income  is  taxed,  which
deductions are eliminated, the percentage of taxpayers subject to each rate, and
whether additional restrictions are placed on municipal bond issuance. We expect
the national  debate to heat up as specific  tax-reform  proposals are put forth
and opponents formulate responses.

                                   2

<PAGE>

Even with tax reform,  your  management is confident that  municipal  bonds will
continue to play a significant role for investors, especially given their recent
value and limited  supply.  In  addition,  the Fund's  conservative  positioning
should be effective in minimizing the effects of interest rate changes and other
external  events.  We believe our strategy  will offer share-  owners  rewarding
performance and a high level of comfort.

The Lehman Brothers Municipal Bond Index is an unmanaged, composite measure 
of investment-grade municipal bonds. The Index's returns assume reinvestment 
of dividends, but, unlike the Fund's returns, do not reflect any fees, expenses 
or sales charges. Investors cannot invest directly in the Index. 

Past  performance  does not  guarantee  future  results.  Return  and  principal
fluctuate,  and your shares, when redeemed, may be worth more or less than their
original  cost.  A portion of income  may be  subject to state and local  taxes,
although the Fund intends to minimize any taxable income.

NOTES TO FINANCIAL STATEMENTS -- SEPTEMBER 30, 1995 

1. Pioneer  California  Double Tax-Free Fund (the Fund), one of three funds that
currently  composes  Pioneer  Tax-Free  State Series Trust,  is a  Massachusetts
business  trust  registered  under  the  Investment  Company  Act of  1940  as a
non-diversified,  open-end  management  investment  company. As of September 30,
1995, The Pioneer Group,  Inc. (PGI) was the beneficial  owner of  approximately
19% of the  outstanding  shares  of the Fund.  The  following  is a  summary  of
significant  accounting policies consistently followed by the Fund, which are in
conformity with those generally accepted in the investment company industry.

A.  Security  Valuation  -- Security  transactions  are  recorded on trade date.
Securities are valued based on valuations  furnished by an  independent  pricing
service that utilizes a matrix system.  This matrix system reflects such factors
as security prices, yields, maturities and ratings and is supplemented by dealer
and exchange quotations and fair market value information from other sources, as
required.  Market  discount  and premium are  accreted or  amortized  daily on a
straight-line  basis.  Original  issue  discount is  accreted  daily to interest
income on a yield-to-  maturity basis.  Temporary cash investments are valued at
amortized cost plus accrued interest,  which approximates value. Interest income
is recorded on the accrual basis.

    Gains and losses on sales of investments are calculated on the "identified 
cost" method for both financial reporting and federal income tax purposes. It 
is the Fund's practice to first select for sale those securities that have the 
highest cost and also qualify for long-term capital gain or loss treatment for 
tax purposes. 

    B. Federal Taxes -- It is the Fund's policy to comply with the requirements 
of the Internal Revenue Code applicable to regulated investment companies and 
to distribute all of its taxable income and net realized capital gains, if any, 
to its shareholders. Therefore, no federal income tax provision is required. 

The  characterization  of distributions to shareholders for financial  reporting
purposes is determined in accordance  with federal income tax rules.  Therefore,
the  source  of the  Fund's  distributions  may  be  shown  in the  accompanying
financial statements as either from or in excess of net investment income or net
realized gain on investment transactions,  or from paid-in capital, depending on
the type of book/tax differences that may exist.

C. Trust Shares -- The Fund records sales and repurchases of its trust shares on
trade  date.  Shares are sold and  redeemed on a  continuous  basis at net asset
value per share. Net losses,  if any, as a result of cancellations  are absorbed
by Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the Fund
and an indirect subsidiary of PGI. PFD earned $5,877 in underwriting commissions
on the sale of the Fund's trust shares during the year ended September 30, 1995.
The Fund declares as daily  dividends  substantially  all of its net  investment
income. All dividends are paid on the last business day of the month. Short-term
capital gain distributions, if any, may be paid with the daily dividends.

2. Pioneering  Management  Corporation  (PMC),  the Fund's  investment  adviser,
manages the Fund's portfolio and is a wholly owned subsidiary of PGI. Management
fees are  calculated  daily at the annual  rate of 0.60% of the  Fund's  average
daily net assets.

    PMC has agreed not to impose a portion of its management fees and to assume 
other  operating  expenses  for the Fund to the  extent  necessary  to limit the
Fund's  expenses  to an annual  rate of 0.50% of the  Fund's  average  daily net
assets up
to $20 million; 0.55% of the next $5 million; 0.60% of the next $5 million; 
0.65% of the next $5 million; 0.70% of the next $5 million; and 0.75% of the 
excess over $40 million. PMC's agreement is temporary and voluntary and may 
be revised or terminated at any time. 

    In addition, under the management agreement, certain other services and 
costs, including accounting, regulatory reporting and insurance premiums, are 
paid by the Fund. Included in Accrued expenses is $4,504 in accounting fees 
payable to PMC at September 30, 1995. 

    3. Pioneering Services Corporation (PSC), a wholly owned subsidiary of PGI, 
provides substantially all transfer agent and shareholder services to the Fund 
at negotiated rates. Included in Accrued expenses is $618 in transfer agent 
fees payable to PSC at September 30, 1995. 

4. The Fund adopted a Plan of  Distribution  (the Plan) that allows for the Fund
to reimburse PFD for expenditures to finance any activities  primarily  intended
to result in the sale of trust shares.  The Plan provides for  reimbursement  of
such  expenditures  in an amount not to exceed 0.25% of the Fund's average daily
net assets.  In addition,  a service fee of 0.15% of the Fund's daily net assets
is accrued daily and paid quarterly.  Included in Accrued  expenses is $4,141 in
distribution fees payable to PFD at September 30, 1995.

                       PIONEER TAX-FREE STATE SERIES TRUST


         DISTRIBUTION  PLAN, dated as of , 1992 of PIONEER TAX FREE STATE SERIES
TRUST, a Massachusetts business trust (the "Trust").

                                   WITNESSETH

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

         WHEREAS,  the Trust  intends to  distribute  its  shares of  beneficial
interest (the  "Shares") of the  securities  portfolio of each series of Pioneer
which  the  Trustees  may  establish  from  time to time  (the  "Portfolio")  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  Distribution Plan
(the "Plan") as a plan of distribution pursuant to such rule;

         WHEREAS, the Trust desires to engage Pioneer Funds Distributor, Inc., a
Massachusetts  corporation ("PFD"), to provide certain distribution services for
the Trust in connection with the plan;

         WHEREAS, the Trust desires to enter into an underwriting agreement with
PFD,  whereby PFD will provide  facilities and personnel and render  services to
the Trust in  connection  with the  offering  and  distribution  of Shares  (the
"Underwriting Agreement");

         WHEREAS,  the Trust also  recognizes and agrees that (a) PFD may retain
the  services  of  firms  or  individuals  to  act  as  dealers  or  wholesalers
(collectively,  the "Dealers") of the Shares in connection  with the offering of
Shares,  (b) PFD may compensate any Dealer that sell 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,  its profits or any other source  available to
it; and

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


<PAGE>


likelihood  that the adoption and  implementation  of this Plan will benefit the
Trust and its shareholders;

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

         1. The Trust may expend  pursuant  to this Plan  amounts  not to exceed
 .25% of 1% of the average daily net assets of each Portfolio per annum.

         2. Subject to the limit in paragraph 1, the Trust shall  reimburse  PFD
for amounts expended by PFD to finance any activity which is primarily  intended
to result in the sale of shares of the Trust or the  provision  of  services  to
shareholders  of the Trust,  including but not limited to  commissions  or other
payments to Dealers and salaries  and other  expenses of PFD relating to selling
or servicing  efforts,  provided,  that the Board of Trustees of the Trust shall
approve categories of expenses for which reimbursement shall be made pursuant to
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  25/100 of 1% per annum of
each  Portfolio's  daily  net  assets;   (ii)   reimbursement  to  PFD  for  its
expenditures for broker-dealer  commissions and employee compensation on certain
sales  of  the  Trust'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 Trust).  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.  The Trust 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 Trust's  Prospectus  from
time to time. Nothing contained herein is intended to have any effect whatsoever
on PFD's  ability to charge any such sales load or to reallow all or any portion
thereof to Dealers.

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

                                      -2-
<PAGE>

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

         5. This 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
"interested  persons" of the Trust and who have not 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.

         6. This plan will  remain in effect  indefinately,  provided  that such
continuance  is  "specially  approved  at  least  annually"  by a vote of both a
majority of the Trustees of the Trust and a majority of the Qualified  Trustees.
If such annual  approval is not  obtained,  this plan shall expire on , 1993. In
the event of termination  or  non-continuance  of this Plan,  each Portfolio has
twelve months to reimburse any expense which it incurs prior to such termination
or  non-continuance,  provided  that  payments  by such  Portfolio  during  such
twelve-month  period shall not exceed 25/100 of 1% of each  Portfolio's  average
daily net assets during such period.

         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 net assets which may be expended  hereunder
without  the  approval  of  holders of a  "majority  of the  outstanding  voting
securities" of the Trust and may not be materially amended in any case without a
vote of a  majority  of  both  the  Trustees  and the  Qualified  Trustees.  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 Trust.

         8. In the event of termination or expiration of the Plan, the Trust may
nevertheless,  within twelve months of such termination or expiration  reimburse
any expense which it incurs prior to such  termination or  expiration,  provided
that payments by the Trust during such twelve-month period shall not exceed .25%
or 1% of the Trust's  average net daily  assets  during such period and provided
further that such payments are specifically approved by



                                      -3-

the Board of Trustees, including a majority of the Qualified  Trustees.

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

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

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

         12. The Trust shall  preserve  copies of this Plan,  and each agreement
related hereto and each report referred to in paragraph 9 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.

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

         14. If any  provisions  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.
