PROSPECTUS
   
NOVEMBER 14, 1995     
                MERRILL LYNCH PENNSYLVANIA MUNICIPAL BOND FUND
               MERRILL LYNCH MULTI-STATE MUNICIPAL SERIES TRUST
   P.O. BOX 9011, PRINCETON, NEW JERSEY 08543-9011-PHONE NO. (609) 282-2800
   
  Merrill Lynch Pennsylvania Municipal Bond Fund (the "Fund") is a mutual fund
seeking to provide shareholders with as high a level of income exempt from
Federal and Pennsylvania personal income taxes as is consistent with prudent
investment management. The Fund invests primarily in a portfolio of long-term,
investment grade obligations issued by or on behalf of the Commonwealth of
Pennsylvania, its political subdivisions, agencies and instrumentalities and
obligations of other qualifying issuers, such as issuers located in Puerto
Rico, the Virgin Islands, and Guam, which pay interest exempt, in the opinion
of bond counsel to the issuer, from Federal and Pennsylvania personal income
taxes ("Pennsylvania Municipal Bonds"). Dividends paid by the Fund are exempt
from Federal and Pennsylvania personal income taxes to the extent they are
derived from Pennsylvania Municipal Bonds. The Fund may invest in certain tax-
exempt securities classified as "private activity bonds" that may subject
certain investors in the Fund to an alternative minimum tax. At times, the
Fund may seek to hedge its portfolio through the use of futures transactions
and options. There can be no assurance that the investment objective of the
Fund will be realized. For more information on the Fund's investment objective
and policies, please see "Investment Objective and Policies" on page 9.     
 
                               ----------------
  Pursuant to the Merrill Lynch Select Pricing SM System, the Fund offers four
classes of shares, each with a different combination of sales charges, ongoing
fees and other features. The Merrill Lynch Select Pricing SM System permits an
investor to choose the method of purchasing shares that the investor believes
is most beneficial given the amount of the purchase, the length of time the
investor expects to hold the shares and other relevant circumstances. See
"Merrill Lynch Select Pricing SM System" on page 4.
   
  Shares may be purchased directly from Merrill Lynch Funds Distributor, Inc.
(the "Distributor"), P.O. Box 9081, Princeton, New Jersey 08543-9081 [(609)
282-2800], or from securities dealers which have entered into dealer
agreements with the Distributor, including Merrill Lynch, Pierce, Fenner &
Smith Incorporated ("Merrill Lynch"). The minimum initial purchase is $1,000
and the minimum subsequent purchase is $50. Merrill Lynch may charge its
customers a processing fee (presently $4.85) for confirming purchases and
repurchases. Purchases and redemptions directly through the Fund's Transfer
Agent are not subject to the processing fee. See "Purchase of Shares" and
"Redemption of Shares".     
 
                               ----------------
THESE SECURITIES HAVE  NOT BEEN APPROVED OR DISAPPROVED  BY THE SECURITIES AND
EXCHANGE COMMISSION OR ANY STATE  SECURITIES COMMISSION NOR HAS THE SECURITIES

  The foregoing Fee Table is intended to assist investors in understanding the
costs and expenses that a shareholder in the Fund will bear directly or
indirectly. The Example set forth above assumes reinvestment of all dividends
and distributions and utilizes a 5% annual rate of return as mandated by the
regulations of the Commission. THE EXAMPLE SHOULD NOT BE CONSIDERED A
REPRESENTATION OF PAST OR FUTURE EXPENSES OR ANNUAL RATE OF RETURN, AND ACTUAL
EXPENSES OR ANNUAL RATES OF RETURN MAY BE MORE OR LESS THAN THOSE ASSUMED FOR
PURPOSES OF THE EXAMPLE. Class B and Class C shareholders who hold their shares
for an extended period of time may pay more in Rule 12b-1 distribution fees
than the economic equivalent of the maximum front-end sales charge permitted
under the Rules of Fair Practice of the National Association of Securities
Dealers, Inc. ("NASD"). Merrill Lynch may charge its customers a processing fee
(presently $4.85) for confirming purchases and repurchases. Purchases and
redemptions directly through the Fund's Transfer Agent are not subject to the
processing fee. See "Purchase of Shares" and "Redemption of Shares."

                   MERRILL LYNCH SELECT PRICING (SM) SYSTEM
   
  The Fund offers four classes of shares under the Merrill Lynch Select
Pricing (SM) System. The shares of each class may be purchased at a price equal
to the next determined net asset value per share subject to the sales charges
and ongoing fee arrangements described below. Shares of Class A and Class D
are sold to investors choosing the initial sales charge alternatives, and
shares of Class B and Class C are sold to investors choosing the deferred
sales charge alternatives. The Merrill Lynch Select Pricing (SM) System is used
by more than 50 mutual funds advised by Merrill Lynch Asset Management, L.P.
("MLAM") or an affiliate of MLAM, Fund Asset Management, L.P. ("FAM" or the
"Manager"). Funds advised by MLAM or FAM are referred to herein as "MLAM-
advised mutual funds".     
   
  Each Class A, Class B, Class C or Class D share of the Fund represents an
identical interest in the investment portfolio of the Fund and has the same
rights, except that Class B, Class C and Class D shares bear the expenses of
the ongoing account maintenance fees and Class B and Class C shares bear the
expenses of the ongoing distribution fees and the additional incremental
transfer agency costs resulting from the deferred sales charge arrangements.
The deferred sales charges and account maintenance fees that are imposed on
Class B and Class C shares, as well as the account maintenance fees that are
imposed on the Class D shares, are imposed directly against those classes and
not against all assets of the Fund and, accordingly, such charges will not
affect the net asset value of any other class or have any impact on investors
choosing another sales charge option. Dividends paid by the Fund for each
class of shares will be calculated in the same manner at the same time and
will differ only to the extent that account maintenance and distribution fees
and any incremental transfer agency costs relating to a particular class are
borne exclusively by that class. Each class has different exchange privileges.
See "Shareholder Services--Exchange Privilege".     
 
  Investors should understand that the purpose and function of the initial
sales charges with respect to the Class A and Class D shares are the same as
those of the deferred sales charges with respect to the Class B and Class C
shares in that the sales charges applicable to each class provide for the
financing of the distribution of the shares of the Fund. The distribution-
related revenues paid with respect to a class will not be used to finance the
distribution expenditures of another class. Sales personnel may receive
different compensation for selling different classes of shares.
 
  The following table sets forth a summary of the distribution arrangements
for each class of shares under the Merrill Lynch Select Pricing (SM) System,
followed by a more detailed description of each class and a discussion of the
factors that investors should consider in determining the method of purchasing
shares under the Merrill Lynch Select Pricing (SM) System that the investor
believes is most beneficial under his particular circumstances. More detailed
information as to each class of shares is set forth under "Purchase of
Shares".

</TABLE>
- --------
(1) Initial sales charges are imposed at the time of purchase as a percentage
    of the offering price. CDSCs are imposed if the redemption occurs within
    the applicable CDSC time period. The charge will be assessed on an amount
    equal to the lesser of the proceeds of redemption or the cost of the
    shares being redeemed.
(2) Offered only to eligible investors. See "Purchase of Shares--Initial Sales
    Charge Alternatives--Class A and Class D Shares--Eligible Class A
    Investors."
   
(3) Reduced for purchases of $25,000 or more. Class A and Class D share
    purchases of $1,000,000 or more may not be subject to an initial sales
    charge but instead will be subject to a 1.0% CDSC if redeemed within one
    year. See "Class A" and "Class D" below.     
   
(4) The conversion period for dividend reinvestment shares was modified. Also,
    Class B shares of certain other MLAM-advised mutual funds into which
    exchanges may be made have an eight year conversion period. If Class B
    shares of a Fund are exchanged for Class B shares of another MLAM-advised
    mutual fund, the conversion period applicable to the Class B shares
    acquired in the exchange will apply, and the holding period for the shares
    exchanged will be tacked onto the holding period for the shares acquired.
           
Class A: Class A shares incur an initial sales charge when they are purchased
         and bear no ongoing distribution or account maintenance fees. Class A
         shares are offered to a limited group of investors and also will be
         issued upon reinvestment of dividends on outstanding Class A shares.
         Investors that currently own Class A shares in a shareholder account
         are entitled to purchase additional Class A shares in that account.
         In addition, Class A shares will be offered to Merrill Lynch & Co.,
         Inc. ("ML & Co.") and its subsidiaries (the term "subsidiaries", when
         used herein with respect to ML & Co., includes MLAM, the Manager and
         certain other entities directly or indirectly wholly-owned and
         controlled by ML & Co.) and their directors and employees, and to
         members of the Boards of MLAM-advised mutual funds. The maximum
         initial sales charge is 4.00%, which is reduced for purchases of
         $25,000 and over. Purchases of $1,000,000 or more may not be subject
         to an initial sales charge, but if the initial sales charge is
         waived, such purchases may be subject to a CDSC of 1% if the shares
         are redeemed within one year after purchase. Sales charges are also
         reduced under a right of accumulation which takes into account the
         investor's holdings of all classes of all MLAM-advised mutual funds.
         See "Purchase of Shares--Initial Sales Charge Alternatives--Class A
         and Class D Shares."     
   
Class B: Class B shares do not incur a sales charge when they are purchased,
         but they are subject to an ongoing account maintenance fee of 0.25%,
         and an ongoing distribution fee of 0.25% of the Fund's average net
         assets attributable to Class B shares, as well as a CDSC if they are
         redeemed within     
 
                                       5
<PAGE>
 
         four years of purchase. Approximately ten years after issuance, Class B
         shares will convert automatically into Class D shares of the Fund,
         which are subject to a lower account maintenance fee of 0.10% and no
         distribution fee. Class B shares of certain other MLAM-advised mutual
         funds into which exchanges may be made convert into Class D shares
         automatically after approximately eight years. If Class B shares of the
         Fund are exchanged for Class B shares of another MLAM-advised mutual
         fund, the conversion period applicable to the Class B shares acquired
         in the exchange will apply, as will the Class D account maintenance fee
         of the acquired fund upon the conversion, and the holding period for
         the shares exchanged will be tacked onto the holding period for the
         shares acquired. Automatic conversion of Class B shares into Class D
         shares will occur at least once a month on the basis of the relative
         net asset values of the shares of the two classes on the conversion
         date, without the imposition of any sales load, fee or other charge.
         Conversion of Class B shares to Class D shares will not be deemed a
         purchase or sale of the shares for Federal income tax purposes. Shares
         purchased through reinvestment of dividends on Class B shares also will
         convert automatically to Class D shares. The conversion period for
         dividend reinvestment shares is modified as described under "Purchase
         of Shares--Deferred Sales Charge Alternatives--Class B and Class C
         Shares--Conversion of Class B Shares to Class D Shares."
   
Class C: Class C shares do not incur a sales charge when they are purchased,
         but they are subject to an ongoing account maintenance fee of 0.25%
         and an ongoing distribution fee of 0.35% of the Fund's average net
         assets attributable to Class C shares. Class C shares are also subject
         to a CDSC if they are redeemed within one year of purchase. Although
         Class C shares are subject to a 1.0% CDSC for only one year (as
         compared to four years for Class B shares), Class C shares have no
         conversion feature and, accordingly, an investor that purchases Class
         C shares will be subject to distribution fees that will be imposed on
         Class C shares for an indefinite period subject to annual approval by
         the Fund's Board of Trustees and regulatory limitations.     
   
Class D: Class D shares incur an initial sales charge when they are purchased
         and are subject to an ongoing account maintenance fee of 0.10% of the
         Fund's average net assets attributable to Class D shares. Class D
         shares are not subject to an ongoing distribution fee or any CDSC when
         they are redeemed. Purchases of $1,000,000 or more may not be subject
         to an initial sales charge, but if the initial sales charge is waived
         such purchases may be subject to a CDSC of 1.0% if the shares are
         redeemed within one year after purchase. The schedule of initial sales
         charges and reductions for the Class D shares is the same as the
         schedule for Class A shares. Class D shares also will be issued upon
         conversion of Class B shares as described above under "Class B" above.
         See "Purchase of Shares--Initial Sales Charge Alternatives--Class A
         and Class D Shares."     
 
  The following is a discussion of the factors that investors should consider
in determining the method of purchasing shares under the Merrill Lynch Select
Pricing SM System that the investor believes is most beneficial under his
particular circumstances.
 
  Initial Sales Charge Alternatives. Investors who prefer an initial sales
charge alternative may elect to purchase Class D shares or, if an eligible
investor, Class A shares. Investors choosing the initial sales charge
alternative who are eligible to purchase Class A shares should purchase Class A
shares rather than Class D
 
                                       6
<PAGE>
 
   
shares because there is an account maintenance fee imposed on Class D shares.
Investors qualifying for significantly reduced initial sales charges may find
the initial sales charge alternative particularly attractive because similar
sales charge reductions are not available with respect to the deferred sales
charges imposed in connection with purchases of Class B or Class C shares.
Investors not qualifying for reduced initial sales charges who expect to
maintain their investment for an extended period of time also may elect to
purchase Class A or Class D shares, because over time the accumulated ongoing
account maintenance and distribution fees on Class B or Class C shares may
exceed the initial sales charge. Although some investors that previously
purchased Class A shares may no longer be eligible to purchase Class A shares
of other MLAM-advised mutual funds, those previously purchased Class A shares,
together with Class B shares holdings, will count toward a right of
accumulation which may qualify the investor for reduced initial sales charges
on new initial sales charge purchases. In addition, the ongoing Class B and
Class C account maintenance and distribution fees will cause Class B and Class
C shares to have higher expense ratios, pay lower dividends and have lower
total returns than the initial sales charge shares. The ongoing Class D account
maintenance fees will cause Class D shares to have a higher expense ratio, pay
lower dividends and have a lower total return than Class A shares.     
   
  Deferred Sales Charge Alternatives. Because no initial sales charges are
deducted at the time of purchase, Class B and Class C shares provide the
benefit of putting all of the investor's dollars to work from the time the
investment is made. The deferred sales charge alternatives may be particularly
appealing to investors who do not quality for a reduction in initial sales
charges. Both Class B and Class C shares are subject to ongoing account
maintenance fees and distributions fees; however, the ongoing account
maintenance and distribution fees potentially may be offset to the extent any
return is realized on the additional funds initially invested in Class B or
Class C shares. In addition, Class B shares will be converted into Class D
shares of the Fund after a conversion period of approximately ten years, and
thereafter investors will be subject to lower ongoing fees.     
   
  Certain investors may elect to purchase Class B shares if they determine it
to be most advantageous to have all their funds invested initially and intend
to hold their shares for an extended period of time. Investors in Class B
shares should take into account whether they intend to redeem their shares
within the CDSC period and, if not, whether they intend to remain invested
until the end of the conversion period and thereby take advantage of the
reduction in ongoing fees resulting from the conversion into Class D shares.
Other investors, however, may elect to purchase Class C shares if they
determine that it is advantageous to have all their assets invested initially
and they are uncertain as to the length of time they intend to hold their
assets in MLAM-advised mutual funds. Although Class C shareholders are subject
to a shorter CDSC period at a lower rate, they are subject to higher
distribution fees and forgo the Class B conversion feature, making their
investment subject to account maintenance and distribution fees for an
indefinite period of time. In addition, while both Class B and Class C
distribution fees are subject to the limitations on asset-based sales charges
imposed by the NASD, the Class B distribution fees are further limited under a
voluntary waiver of asset-based sales charges. See "Purchase of Shares--
Limitations on the Payment of Deferred Sales Charges."

                       INVESTMENT OBJECTIVE AND POLICIES
 
  The investment objective of the Fund is to provide shareholders with as high
a level of income exempt from Federal and Pennsylvania personal income taxes as
is consistent with prudent investment management. The Fund seeks to achieve its
objective by investing primarily in a portfolio of long-term obligations issued
by or on behalf of the Commonwealth of Pennsylvania, its political
subdivisions, agencies and instrumentalities and obligations of other
qualifying issuers, such as issuers located in Puerto Rico, the Virgin Islands,
and Guam, which pay interest exempt, in the opinion of bond counsel to the
issuer, from Federal and Pennsylvania personal income taxes. Obligations exempt
from Federal income taxes are referred to herein as "Municipal Bonds" and
obligations exempt from both Federal and Pennsylvania income taxes are referred
to as "Pennsylvania Municipal Bonds." Unless otherwise indicated, references to
Municipal Bonds shall be deemed to include Pennsylvania Municipal Bonds. The
Fund at all times, except during temporary defensive periods, will maintain at
least 65% of its total assets invested in Pennsylvania Municipal Bonds. The
investment objective of the Fund as set forth in the first sentence of this
paragraph is a fundamental policy of the Fund which may not be changed without
a vote of a majority of the outstanding shares of the Fund.
   
  Municipal Bonds may include several types of bonds. The interest on Municipal
Bonds may bear a fixed rate or be payable at a variable or floating rate. At
least 80% of the Municipal Bonds purchased by the Fund primarily will be what
are commonly referred to as "investment grade" securities, which are
obligations rated at the time of purchase within the four highest quality
ratings as determined by either Moody's Investors Service ("Moody's")
(currently Aaa, Aa, A and Baa), Standard & Poor's Corporation ("Standard &
Poor's") (currently AAA, AA, A and BBB) or Fitch Investors Service, Inc.
("Fitch") (currently AAA, AA, A and BBB). If Municipal Bonds are unrated, such
securities will possess creditworthiness comparable, in the opinion of the
Manager of the Fund, to obligations in which the Fund may invest. Municipal
Bonds rated in the fourth highest rating category, while considered "investment
grade", have certain speculative characteristics and are more likely to be
downgraded to non-investment grade than obligations rated in one of the top
three rating categories. See Appendix II--"Ratings of Municipal Bonds"--in the
Statement of Additional Information for more information regarding ratings of
debt securities. An issue of rated Municipal Bonds may cease to be rated or its
rating may be reduced below "investment grade" subsequent to its purchase by
the Fund. If an obligation is downgraded below investment grade, the Manager
will consider factors such as price, credit risk, market conditions, financial
condition of the issuer and interest rates to determine whether to continue to
hold the obligation in the Fund's portfolio.     
 
  The Fund may invest up to 20% of its total assets in Municipal Bonds that are
rated below Baa by Moody's or below BBB by Standard & Poor's or Fitch. Such
securities, sometimes referred to as "high-yield" or "junk" bonds, are
predominantly speculative with respect to the capacity to pay interest and
repay principal in accordance with the terms of the security and generally
involve a greater volatility of price than securities in higher rating
categories. The market prices of high-yielding, lower-rated securities may
fluctuate more than higher-rated securities and may decline significantly in
periods of general economic difficulty, which may follow periods of rising
interest rates. In purchasing such securities, the Fund will rely on the
Manager's judgment, analysis and experience in evaluating the creditworthiness
of the issuer of such securities. The Manager will take into consideration,
among other things, the issuer's financial resources, its sensitivity to
economic conditions and trends, its operating history, the quality of its
management and regulatory matters. See "Investment Objective and Policies" in
the Statement of Additional Information for
 
                                       9

a more detailed discussion of the pertinent risk factors involved in investing
in "high yield" or "junk" bonds and Appendix II--"Ratings of Municipal Bonds"--
in the Statement of Additional Information for additional information regarding
ratings of debt securities. The Fund does not intend to purchase debt
securities that are in default or which the Manager believes will be in
default.     
 
  Certain Municipal Bonds may be entitled to the benefits of letters of credit
or similar credit enhancements issued by financial institutions. In such
instances, the Trustees and the Manager will take into account in assessing the
quality of such bonds not only the creditworthiness of the issuer of such bonds
but also the creditworthiness of the financial institution.
 
  The Fund's investments include variable rate demand obligations ("VRDOs") and
VRDOs in the form of participation interests ("Participating VRDOs") in
variable rate tax-exempt obligations held by a financial institution. The VRDOs
in which the Fund will invest are tax-exempt obligations which contain a
floating or variable interest rate adjustment formula and an unconditional
right of demand on the part of the holder thereof to receive payment of the
unpaid principal balance plus accrued interest on a short notice period not to
exceed seven days. Participating VRDOs provide the Fund with a specified
undivided interest (up to 100%) of the underlying obligation and the right to
demand payment of the unpaid principal balance plus accrued interest on the
Participating VRDOs from the financial institution on a specified number of
days' notice, not to exceed seven days. There is, however, some possibility
that because of default or insolvency, the demand feature of VRDOs or
Participating VRDOs may not be honored. The Fund has been advised by its
counsel that the Fund should be entitled to treat the income received on
Participating VRDOs as interest from tax-exempt obligations.
 
  VRDOs that contain an unconditional right of demand to receive payment of the
unpaid principal balance plus accrued interest on a notice period exceeding
seven days may be deemed to be illiquid securities. A VRDO with a demand notice
exceeding seven days will therefore be subject to the Fund's restriction on
illiquid investments unless, in the judgment of the Trustees, such VRDO is
liquid. The Trustees may adopt guidelines and delegate to the Manager the daily
function of determining and monitoring liquidity of such VRDOs. The Trustees,
however, will retain sufficient oversight and be ultimately responsible for
such determination.
 
  The Fund ordinarily does not intend to realize investment income not exempt
from Federal and Pennsylvania income taxes. However, to the extent that
suitable Pennsylvania Municipal Bonds are not available for investment by the
Fund, the Fund may purchase Municipal Bonds issued by other states, their
agencies and instrumentalities, the interest income on which is exempt, in the
opinion of bond counsel, from Federal, but not Pennsylvania, taxation. The Fund
also may invest in securities not issued by or on behalf of a state or
territory or by an agency or instrumentality thereof, if the Fund nevertheless
believes such securities to be exempt from Federal income taxation ("Non-
Municipal Tax-Exempt Securities"). Non-Municipal Tax-Exempt Securities also may
include securities issued by other investment companies that invest in
municipal bonds, to the extent such investments are permitted by the Investment
Company Act of 1940, as amended (the "1940 Act"). Other Non-Municipal Tax-
Exempt Securities could include trust certificates or other instruments
evidencing interests in one or more long-term municipal securities.
 
  Under normal circumstances, except when acceptable securities are unavailable
as determined by the Manager, the Fund will invest at least 65% of its total
assets in Pennsylvania Municipal Bonds. For
 
                                       10
<PAGE>
 
   
temporary defensive periods or to provide liquidity, the Fund has the authority
to invest as much as 35% of its total assets in tax-exempt or taxable money
market obligations with a maturity of one year or less (such short-term
obligations being referred to herein as "Temporary Investments"), except that
taxable Temporary Investments shall not exceed 20% of the Fund's net assets.
The Temporary Investments, VRDOs and Participating VRDOs in which the Fund may
invest also will be in the following rating categories at the time of purchase:
MIG-1/VMIG-1 through MIG-4/VMIG-4 for notes and VRDOs and Prime-1 through
Prime-3 for commercial paper (as determined by Moody's), SP-1+ through SP-2 for
notes and A-1+ through A-3 for VRDOs and commercial paper (as determined by
Standard & Poor's), or F-1+ through F-3 for notes, VRDOs and commercial paper
(as determined by Fitch) or, if unrated, of comparable quality in the opinion
of the Manager. The Fund at all times will have at least 80% of its net assets
invested in securities the interest on which is exempt from Federal taxation.
However, interest received on certain otherwise tax-exempt securities which are
classified as "private activity bonds" (in general, bonds that benefit non-
governmental entities) may be subject to Federal alternative minimum tax. The
percentage of the Fund's net assets invested in "private activity bonds" will
vary during the year. See "Distributions and Taxes". In addition, the Fund
reserves the right to invest temporarily a greater portion of its assets in
Temporary Investments for defensive purposes, when, in the judgment of the
Manager, market conditions warrant. The investment objective of the Fund is a
fundamental policy of the Fund which may not be changed without a vote of a
majority of the outstanding shares of the Fund. The Fund's hedging strategies,
which are described in more detail under "Financial Futures Transactions and
Options," are not fundamental policies and may be modified by the Trustees of
the Trust without the approval of the Fund's shareholders.     
 
POTENTIAL BENEFITS
 
  Investment in shares of the Fund offers several benefits. The Fund offers
investors the opportunity to receive income exempt from Federal and
Pennsylvania personal income taxes by investing in a professionally managed
portfolio of long-term Pennsylvania Municipal Bonds. The Fund also provides
liquidity because of its redemption features and relieves the investor of the
burdensome administrative details involved in managing a portfolio of tax-
exempt securities. The benefits are at least partially offset by the expenses
involved in operating an investment company. Such expenses primarily consist of
the management fee and operational costs and, in the case of certain classes of
shares, the account maintenance and distribution costs.
   
SPECIAL AND RISK CONSIDERATIONS RELATING TO MUNICIPAL BONDS     
   
  The risks and special considerations involved in investments in Municipal
Bonds vary with the types of instruments being acquired. Investments in Non-
Municipal Tax-Exempt Securities may present similar risks, depending on the
particular product. Certain instruments in which the Fund may invest may be
characterized as derivative instruments. See "Description of Municipal Bonds"
and "Financial Futures Transactions and Options".     
   
  Moreover, the Fund ordinarily will invest at least 65% of its total assets in
Pennsylvania Municipal Bonds, and therefore it is more susceptible to factors
adversely affecting issuers of Pennsylvania Municipal Bonds than is a municipal
bond mutual fund that is not concentrated in issuers of Pennsylvania Municipal
Bonds to this degree.     
 
 
                                       11

  Many different social, environmental and economic factors may affect the
financial condition of Pennsylvania and its political subdivisions. From time
to time Pennsylvania and certain of its political subdivisions have encountered
financial difficulties which have adversely affected their respective credit
standings. For example, the financial condition of the City of Philadelphia had
impaired its ability to borrow and resulted in its obligations generally being
downgraded by the major rating services to below investment grade. Other
factors which may negatively affect economic conditions in Pennsylvania include
adverse changes in employment rates, Federal revenue sharing or laws with
respect to tax-exempt financing. Currently, Pennsylvania's general obligation
bonds are rated AA- by Standard & Poor's and Fitch and A1 by Moody's. See
"Description of Municipal Bonds" in the Statement of Additional Information and
see also Appendix I to the Statement of Additional Information.
 
DESCRIPTION OF MUNICIPAL BONDS
   
  Municipal Bonds include debt obligations issued to obtain funds for various
public purposes, including construction and equipping of a wide range of public
facilities (including water, sewer, gas, electricity, solid waste, health care,
transportation, education and housing facilities), refunding of outstanding
obligations and obtaining funds for general operating expenses and loans to
other public institutions and facilities. In addition, certain types of bonds
are issued by or on behalf of public authorities to finance various privately
operated facilities, including certain facilities for local furnishing of
electric energy or gas, sewage facilities, solid waste disposal facilities and
other specialized facilities. For purposes of this Prospectus, such obligations
are Municipal Bonds if the interest paid thereon is excluded from gross income
for Federal income tax purposes ("exempt from Federal income tax") and, in the
case of Pennsylvania Municipal Bonds, exempt from Pennsylvania personal income
tax, even though such bonds may be IDBs or "private activity bonds" as
discussed below.     
   
  The two principal classifications of Municipal Bonds are "general obligation"
and "revenue" bonds which latter category includes industrial development bonds
("IDBs") and, for bonds issued after August 15, 1986, private activity bonds.
General obligation bonds are secured by the issuer's pledge of its faith,
credit and taxing power for the payment of principal and interest. The taxing
power of any governmental entity may be limited, however, by provisions of
state constitutions or laws, and an entity's creditworthiness will depend on
many factors, including potential erosion of the tax base due to population
declines, natural disasters, declines in the state's industrial base or
inability to attract new industries, economic limits on the ability to tax
without eroding the tax base, state legislative proposals or voter initiatives
to limit ad valorem real property taxes, and the extent to which the entity
relies on Federal or state aid, access to capital markets or other factors
beyond the state or entity's control. Accordingly, the capacity of the issuer
of a general obligation bond as to the timely payment of interest and the
repayment of principal when due is affected by the issuer's maintenance of its
tax base.     
   
  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 tax or other specific revenue source such as from the user of
the facility being financed; accordingly, the timely payment of interest and
the repayment of principal in accordance with the terms of the revenue or
special obligation bond is a function of the economic viability of such
facility or such revenue source. The Fund will not invest in IDBs where the
entity supplying the revenues from which the issuer is paid, including
predecessors, has a record of less than three years of     
 
                                       12
<PAGE>
 
   
continuous business operations, if such investments, together with investments
in other unseasoned issuers, would exceed 5% of the Fund's total assets.
Investments involving entities with less than three years of continuous
business operations may pose somewhat greater risks due to the lack of a
substantial operating history for such entities. The Manager believes, however,
that the potential benefits of such investments outweigh the potential risks,
particularly given the Fund's limitations on such investments.     
   
  The Fund may purchase IDBs or private activity bonds. IDBs or private
activity bonds are tax-exempt securities issued by states, municipalities or
public authorities and are issued to provide funds, usually through a loan or
lease arrangement, to a private corporation for the purpose of financing
construction or improvement of a facility to be used by the corporation. Such
bonds are secured primarily by revenues derived from loan repayments or lease
payments due from the corporation which may or may not be guaranteed by a
parent company or otherwise secured. In view of this, an investor should be
aware that repayment of such bonds depends on the revenues of a private
corporation and be aware of the risks that such an investment may entail.
Continued ability of a corporation to generate sufficient revenues for the
payment of principal and interest on such bonds will be affected by many
factors including the size of the corporation, capital structure, demand for
its products or services, competition, general economic conditions, government
regulation and the corporation's dependence on revenues for the operation of
the particular facility being financed. The Fund may also invest in so-called
"moral obligation" bonds, which are normally issued by special purpose public
authorities. If an issuer of moral obligation bonds is unable to meet its
obligations, the repayment of such bonds becomes a moral commitment, but not a
legal obligation, of the state or municipality in question.     
   
  The Fund may invest in Municipal Bonds (and Non-Municipal Tax-Exempt
Securities) the return on which is based on a particular index of value or
interest rates. For example, the Fund may invest in Municipal Bonds that pay
interest based on an index of Municipal Bond interest rates or based on the
value of gold or some other commodity. The principal amount payable upon
maturity of certain Municipal Bonds also may be based on the value of an index.
To the extent the Fund invests in these types of Municipal Bonds, the Fund's
return on such Municipal Bonds will be subject to risk with respect to the
value of the particular index. Interest and principal payable on the Municipal
Bonds may also be based on relative changes among particular indices. Also, the
Fund may invest in so-called "inverse floating obligations" or "residual
interest bonds" on which the interest rates typically decline as market rates
increase and increase as market rates decline. The Fund's return on such types
of Municipal Bonds (and Non-Municipal Tax-Exempt Securities) will be subject to
risk with respect to the value of the particular index, which may include
reduced or eliminated interest payments and losses of invested principal. Such
securities have the effect of providing a degree of investment leverage, since
they may increase or decrease in value in response to changes, as an
illustration, in market interest rates at a rate which is a multiple (typically
two) of the rate at which fixed-rate long term tax exempt securities increase
or decrease in response to such changes. As a result, the market values of such
securities will generally be more volatile than the market values of fixed-rate
tax exempt securities. To seek to limit the volatility of these securities, the
Fund may purchase inverse floating obligations with shorter term maturities or
which contain limitations on the extent to which the interest rate may vary.
The Manager, however, believes that indexed and inverse floating obligations
represent flexible portfolio management instruments for the Fund which allow
the Fund to seek potential investment rewards, hedge other portfolio positions
or vary the degree of investment leverage relatively efficiently under
different market conditions. Certain investments in such obligations may be
illiquid. The Fund may not invest in such illiquid     
 
                                       13
<PAGE>
 
   
obligations if such investments, together with other illiquid investments,
would exceed 15% of the Fund's net assets.     
   
  Also included within the general category of Municipal Bonds are
participation certificates issued by government authorities or entities to
finance the acquisition or construction of equipment, land and/or facilities.
The certificates represent participations in a lease, an installment purchase
contract or a conditional sales contract (hereinafter collectively called
"lease obligations") relating to such equipment, land or facilities. Although
lease obligations do not constitute general obligations of the issuer for which
the issuer's unlimited taxing power is pledged, a lease obligation is
frequently backed by the issuer's covenant to budget for, appropriate and make
the payments due under the lease obligation. However, certain lease obligations
contain "non-appropriation" clauses which provide that the issuer has no
obligation to make lease or installment purchase payments in future years
unless money is appropriated for such purpose on a yearly basis. Although "non-
appropriation" lease obligations are secured by the leased property,
disposition of the property in the event of foreclosure might prove difficult.
These securities represent a type of financing that has not yet developed the
depth of marketability associated with more conventional securities. Certain
investments in lease obligations may be illiquid. The Fund may not invest in
illiquid lease obligations if such investments, together with all other
illiquid investments, would exceed 15% of the Fund's total assets. The Fund
may, however, invest without regard to such limitation in lease obligations
which the Manager, pursuant to guidelines which have been adopted by the Board
of Trustees and subject to the supervision of the Board, determines to be
liquid. The Manager will deem lease obligations to be liquid if they are
publicly offered and have received an investment grade rating of Baa or better
by Moody's, or BBB or better by Standard & Poor's or Fitch. Unrated lease
obligations, or those rated below investment grade, will be considered liquid
if the obligations come to the market through an underwritten public offering
and at least two dealers are willing to give competitive bids. In reference to
obligations rated below investment grade, the Manager must, among other things,
also review the creditworthiness of the municipality obligated to make payment
under the lease obligation and make certain specified determinations based on
such factors as the existence of a rating or credit enhancement such as
insurance, the frequency of trades or quotes for the obligation and the
willingness of dealers to make a market in the obligation.     
 
  Federal tax legislation has limited the types and volume of bonds the
interest on which qualifies for a Federal income tax exemption. As a result,
this legislation and legislation which may be enacted in the future may affect
the availability of Municipal Bonds for investment by the Fund.
 
CALL RIGHTS
   
  The Fund may purchase a Municipal Bond issuer's right to call all or a
portion of such Municipal Bond for mandatory tender for purchase (a "Call
Right"). A holder of a Call Right may exercise such right to require a
mandatory tender for the purchase of related Municipal Bonds, subject to
certain conditions. A Call Right that is not exercised prior to the maturity of
the related Municipal Bond will expire without value. The economic effect of
holding both the Call Right and the related Municipal Bond is identical to that
of holding a Municipal Bond as a non-callable security. Certain investments in
such obligations may be illiquid. The Fund may not invest in such illiquid
obligations if such investments, together with other illiquid investments,
would exceed 15% of the Fund's total assets.     
 
 
                                       14
<PAGE>
 
WHEN-ISSUED SECURITIES AND DELAYED DELIVERY TRANSACTIONS
 
  The Fund may purchase or sell Municipal Bonds on a delayed delivery basis or
a when-issued basis at fixed purchase terms. These transactions arise when
securities are purchased or sold by the Fund with payment and delivery taking
place in the future. The purchase will be recorded on the date the Fund enters
into the commitment and the value of the obligation will thereafter be
reflected in the calculation of the Fund's net asset value. The value of the
obligation on the delivery date may be more or less than its purchase price. A
separate account of the Fund will be established with its custodian consisting
of cash, cash equivalents or high grade, liquid Municipal Bonds having a market
value at all times at least equal to the amount of the forward commitment.
 
FINANCIAL FUTURES TRANSACTIONS AND OPTIONS
 
  The Fund is authorized to purchase and sell certain exchange traded financial
futures contracts ("financial futures contracts") solely for the purpose of
hedging its investments in Municipal Bonds against declines in value and to
hedge against increases in the cost of securities it intends to purchase.
However, any transactions involving financial futures or options (including
puts and calls associated therewith) will be in accordance with the Fund's
investment policies. A financial futures contract obligates the seller of a
contract to deliver and the purchaser of a contract to take delivery of the
type of financial instrument covered by the contract, or in the case of index-
based futures contracts to make and accept a cash settlement, at a specific
future time for a specified price. A sale of financial futures contracts may
provide a hedge against a decline in the value of portfolio securities because
such depreciation may be offset, in whole or in part, by an increase in the
value of the position in the financial futures contracts. A purchase of
financial futures contracts may provide a hedge against an increase in the cost
of securities intended to be purchased, because such appreciation may be
offset, in whole or in part, by an increase in the value of the position in the
futures contracts. Distributions, if any, of net long-term capital gains from
certain transactions in futures or options are taxable at long-term capital
gains rates for Federal income tax purposes, regardless of the length of time
the shareholder has owned Fund shares. See "Distributions and Taxes--Taxes".
 
  The Fund deals in financial futures contracts traded on the Chicago Board of
Trade based on The Bond Buyer Municipal Bond Index, a price-weighted measure of
the market value of 40 large, recently issued tax-exempt bonds. There can be no
assurance, however, that a liquid secondary market will exist to terminate any
particular financial futures contract at any specific time. If it is not
possible to close a financial futures position entered into by the Fund, the
Fund would continue to be required to make daily cash payments of variation
margin in the event of adverse price movements. In such a situation, if the
Fund has insufficient cash, it may have to sell portfolio securities to meet
daily variation margin requirements at a time when it may be disadvantageous to
do so. The inability to close financial futures positions also could have an
adverse impact on the Fund's ability to hedge effectively. There is also the
risk of loss by the Fund of margin deposits in the event of bankruptcy of a
broker with whom the Fund has an open position in a financial futures contract.
 
  The Fund may purchase and sell financial futures contracts on U.S. Government
securities and write and purchase put and call options on such futures
contracts as a hedge against adverse changes in interest rates as described
more fully in the Statement of Additional Information. With respect to U.S.
Government securities, currently there are financial futures contracts based on
long-term U.S. Treasury bonds, Treasury
 
                                       15
<PAGE>
 
notes, Government National Mortgage Association ("GNMA") Certificates and
three-month U.S. Treasury bills.
 
  Subject to policies adopted by the Trustees, the Fund also may engage in
other financial futures contracts transactions and options thereon, such as
financial futures contracts or options on other municipal bond indexes which
may become available if the Manager of the Fund and the Trustees of the Trust
should determine that there is normally a sufficient correlation between the
prices of such futures contracts and the Municipal Bonds in which the Fund
invests to make such hedging appropriate.
 
  Utilization of futures transactions and options thereon involves the risk of
imperfect correlation in movements in the price of futures contracts and
movements in the price of the security which is the subject of the hedge. If
the price of the futures contract moves more or less than the price of the
security that is the subject of the hedge, the Fund will experience a gain or
loss which will not be completely offset by movements in the price of such
security. There is a risk of imperfect correlation where the securities
underlying futures contracts have different maturities, ratings or geographic
mixes than the security being hedged. In addition, the correlation may be
affected by additions to or deletions from the index which serves as a basis
for a financial futures contract. Finally, in the case of futures contracts on
U.S. Government securities and options on such futures contracts, the
anticipated correlation of price movements between the U.S. Government
securities underlying the futures or options and Municipal Bonds may be
adversely affected by economic, political, legislative or other developments
which have a disparate impact on the respective markets for such securities.
 
  Under regulations of the Commodity Futures Trading Commission, the futures
trading activities described herein will not result in the Fund being deemed to
be a "commodity pool", as defined under such regulations, provided that the
Fund adheres to certain restrictions. In particular, the Fund may purchase and
sell futures contracts and options thereon (i) only for bona fide hedging
purposes, and (ii) for non-hedging purposes, if the aggregate initial margins
and premiums required to establish positions in such contracts and options does
not exceed 5% of the liquidation value of the Fund's portfolio assets after
taking into account unrealized profits and unrealized losses on any such
contracts and options. (However, as stated above, the Fund intends to engage in
options and futures transactions only for hedging purposes.) Margin deposits
may consist of cash or securities acceptable to the broker and the relevant
contract market.
 
  When the Fund purchases a futures contract, or writes a put option or
purchases a call option thereon, it will maintain an amount of cash, cash
equivalents (e.g., high grade commercial paper and daily tender adjustable
notes) or short-term, high-grade, fixed-income securities in a segregated
account with the Fund's custodian, so that the amount so segregated plus the
amount of initial and variation margin held in the account of its broker equals
the market value of the futures contracts, thereby ensuring that the use of
such futures contract is unleveraged. It is not anticipated that transactions
in futures contracts will have the effect of increasing portfolio turnover.
 
  Although certain risks are involved in options and futures transactions, the
Manager believes that, because the Fund will engage in futures transactions
only for hedging purposes, the futures portfolio strategies of the Fund will
not subject the Fund to certain risks frequently associated with speculation in
futures transactions. The Fund must meet certain Federal income tax
requirements under the Internal Revenue Code of 1986, as amended (the "Code"),
in order to qualify for the special tax treatment afforded regulated
 
                                       16
<PAGE>
 
investment companies, including a requirement that less than 30% of its gross
income be derived from the sale or other disposition of securities held for
less than three months. Additionally, the Fund is required to meet certain
diversification requirements under the Code.
 
  The liquidity of a secondary market in a futures contract may be adversely
affected by "daily price fluctuation limits" established by commodity exchanges
which limit the amount of fluctuation in a futures contract price during a
single trading day. Once the daily limit has been reached in the contract, no
trades may be entered into at a price beyond the limit, thus preventing the
liquidation of open futures positions. Prices have in the past moved beyond the
daily limit on a number of consecutive trading days.
 
  The successful use of transactions in futures also depends on the ability of
the Manager to forecast correctly the direction and extent of interest rate
movements within a given time frame. To the extent these rates remain stable
during the period in which a futures contract is held by the Fund or moves in a
direction opposite to that anticipated, the Fund may realize a loss on the
hedging transaction which is not fully or partially offset by an increase in
the value of portfolio securities. As a result, the Fund's total return for
such period may be less than if it had not engaged in the hedging transaction.
Furthermore, the Fund will only engage in hedging transactions from time to
time and may not necessarily be engaging in hedging transactions when movements
in interest rates occur.
 
  Reference is made to the Statement of Additional Information for further
information on financial futures contracts and certain options thereon.
 
REPURCHASE AGREEMENTS
   
  As Temporary Investments, the Fund may invest in securities pursuant to
repurchase agreements. Repurchase agreements may be entered into only with a
member bank of the Federal Reserve System or a primary dealer in U.S.
Government Securities or an affiliate thereof. Under such agreements, the
seller agrees, upon entering into the contract, to repurchase the security from
the Fund at a mutually agreed upon time and price, thereby determining the
yield during the term of the agreement. This results in a fixed rate of return
insulated from market fluctuations during such period. The Fund may not invest
in repurchase agreements maturing in more than seven days if such investments,
together with the Fund's other illiquid investments, exceed 15% of the Fund's
total assets. In the event of default by the seller under a repurchase
agreement, the Fund may suffer time delays and incur costs or possible losses
in connection with the disposition of the underlying securities.     
 
INVESTMENT RESTRICTIONS
   
  The Fund's investment activities are subject to further restrictions that are
described in the Statement of Additional Information. Investment restrictions
and policies which are fundamental policies may not be changed without the
approval of the holders of a majority of the Fund's outstanding voting
securities, as defined in the 1940 Act. Among its fundamental policies, the
Fund may not: (i) invest more than 25% of its assets, taken at market value at
the time of each investment, in the securities of issuers in any particular
industry (excluding the U.S. Government and its agencies and instrumentalities)
(For purposes of this restriction, states, municipalities and their political
subdivisions are not considered to be part of any industry); and (ii) borrow
money, except that (a) the Fund may borrow from banks (as defined in the 1940
Act) in     
 
                                       17
<PAGE>
 
   
amounts up to 33 1/3% of its total assets (including the amount borrowed), (b)
the Fund may borrow up to an additional 5% of its total assets for temporary
purposes, (c) the Fund may obtain such short-term credit as may be necessary
for the clearance of purchases and sales of portfolio securities and (d) the
Fund may purchase securities on margin to the extent permitted by applicable
law. The Fund may not pledge its assets other than to secure such borrowings
or, to the extent permitted by the Fund's investment policies as set forth in
the Prospectus and Statement of Additional Information, as they may be amended
from time to time, in connection with hedging transactions, short sales, when-
issued and forward commitment transactions and similar investment strategies.
       
  Among its non-fundamental policies, the Fund may not (i) purchase securities
of other investment companies, except to the extent such purchases are
permitted by applicable law; (ii) invest in securities which cannot be readily
resold because of legal or contractual restrictions or which cannot otherwise
be marketed, redeemed or put to the issuer or a third party, if at the time of
acquisition more than 15% of its total assets would be invested in such
securities [This restriction (ii) shall not apply to securities which mature
within seven days or securities which the Board of Trustees of the Trust has
otherwise determined to be liquid pursuant to applicable law]; and (iii) invest
in securities of companies having a record, together with predecessors, of less
than three years of continuous operation, if more than 5% of the Fund's total
assets would be invested in such securities. This restriction (iii) shall not
apply to mortgage-backed securities, asset-backed securities or obligations
issued or guaranteed by the U.S. Government, its agencies or instrumentalities.
    
       
       
  Under prior Pennsylvania law, in order for the Fund to qualify to pass
through to investors income exempt from Pennsylvania personal income tax, the
Fund was required to adhere to certain investment restrictions. In order to
comply with this and other Pennsylvania law requirements previously in effect,
the Fund adopted, as a fundamental policy, a requirement that it invest in
securities for income earnings rather than trading for profit, and that, in
accordance with such policy, it not vary its portfolio investments except to
(i) eliminate unsafe investments or investments not consistent with the
preservation of the capital or the tax status of the investments of the Fund;
(ii) honor redemption orders, meet anticipated redemption requirements, and
negate gains from discount purchases; (iii) reinvest the earnings from
securities in like securities; or (iv) defray normal administrative expenses.
Pennsylvania has recently enacted legislation which eliminated the necessity
for the foregoing investment policies. Since such policies are fundamental
policies of the Fund, which can only be changed by the affirmative vote of a
majority (as defined under the Investment Company Act) of the outstanding
shares, the Fund continues to be governed by such investment policies.
   
  The Fund is classified as non-diversified within the meaning of the 1940 Act,
which means that the Fund is not limited by the 1940 Act in the proportion of
its assets that it may invest in obligations of a single issuer. However, the
Fund's investments will be limited so as to qualify for the special treatment
afforded regulated investment companies under the Code. See "Distributions and
Taxes--Taxes". To qualify, among other requirements, the Trust will limit the
Fund's investments so that, at the close of each quarter of the taxable year,
(i) not more than 25% of the market value of the Fund's total assets will be
invested in the securities of a single issuer, and (ii) with respect to 50% of
the market value of its total assets, not more than 5% of the market value of
its total assets will be invested in the securities of a single issuer and the
Fund will not own more than 10% of the outstanding voting securities of a
single issuer. For purposes of this restriction, the Fund will regard each
state and each political subdivision, agency or instrumentality of such state
and     
 
                                       18
<PAGE>
 
each multi-state agency of which such state is a member and each public
authority which issues securities on behalf of a private entity as a separate
issuer, except that if the security is backed only by the assets and revenues
of a non-government entity then the entity with the ultimate responsibility for
the payment of interest and principal may be regarded as the sole issuer. These
tax-related limitations may be changed by the Trustees of the Trust to the
extent necessary to comply with changes to the Federal tax requirements. A fund
which elects to be classified as "diversified" under the 1940 Act must satisfy
the foregoing 5% and 10% requirements with respect to 75% of its total assets.
To the extent that the Fund assumes large positions in the obligations of a
small number of issuers, the Fund's total return may fluctuate to a greater
extent than that of a diversified company as a result of changes in the
financial condition or in the market's assessment of the issuers.
       
  Investors are referred to the Statement of Additional Information for a
complete description of the Fund's investment restrictions.

MANAGEMENT AND ADVISORY ARRANGEMENTS
   
  The Manager, which is an affiliate of MLAM and is owned and controlled by
ML&Co., a financial services holding company, acts as the manager for the Fund
and provides the Fund with management     
 
                                       19
<PAGE>
 
   
services. The Manager or MLAM acts as the investment adviser for more than 130
other registered investment companies. MLAM also provides investment advisory
services to individual and institutional accounts. As of September 30, 1995,
the Manager and MLAM had a total of approximately $189.4 billion in investment
company and other portfolio assets under management, including accounts of
certain affiliates of the Manager.     
 
  Subject to the direction of the Trustees, the Manager is responsible for the
actual management of the Fund's portfolio and constantly reviews the Fund's
holdings in light of its own research analysis and that from other relevant
sources. The responsibility for making decisions to buy, sell or hold a
particular security rests with the Manager. The Manager performs certain of the
other administrative services and provides all the office space, facilities,
equipment and necessary personnel for management of the Fund.
   
  William Michael Petty is the Portfolio Manager of the Fund. He has been a
Vice President of MLAM since 1993, an Assistant Vice President of MLAM from
1992 to 1993 and a municipal bond broker with J.J. Kenny Municipal Bond Brokers
from 1990 to 1992.     
   
  Pursuant to the management agreement between the Manager and the Trust on
behalf of the Fund (the "Management Agreement"), the Manager is entitled to
receive from the Fund a monthly fee based upon the average daily net assets of
the Fund at the following annual rates: 0.55% of the average daily net assets
not exceeding $500 million; 0.525% of the average daily net assets exceeding
$500 million but not exceeding $1.0 billion and 0.50% of the average daily net
assets exceeding $1.0 billion. For the year ended July 31, 1995, the total fee
paid by the Fund to the Manager was $827,537 (based upon average net assets of
approximately $151.2 million).     
   
  The Management Agreement obligates the Trust on behalf of the Fund to pay
certain expenses incurred in the Fund's operations, including, among other
things, the management fee, legal and audit fees, unaffiliated Trustee's fees
and expenses, registration fees, custodian and transfer agency fees, accounting
and pricing costs, and certain of the costs of printing proxies, shareholder
reports, prospectuses and statements of additional information. Accounting
services are provided to the Fund by the Manager and the Fund reimburses the
Manager for its costs in connection with such services. The Manager may
voluntarily waive all or a portion of its management fee and may voluntarily
assume all or a portion of the Fund's expenses. For the year ended July 31,
1995, the Fund reimbursed the Manager $40,065 for accounting services. For the
year ended July 31, 1995, the ratio of total expenses, net of account
maintenance and distribution fees, to average net assets was .77% for Class A
shares and .78% for Class B shares; for the period October 21, 1994
(commencement of operations) to July 31, 1995, the annualized ratio of total
expenses, net of account maintenance and distribution fees, to average net
assets was .78% for Class C shares and .77% for Class D shares.     
   
CODE OF ETHICS     
   
  The Board of Trustees of the Trust has adopted a Code of Ethics under Rule
17j-1 of the 1940 Act which incorporates the Code of Ethics of the Manager
(together, the "Codes"). The Codes significantly restrict the personal
investing activities of all employees of the Manager and, as described below,
impose additional, more onerous, restrictions on fund investment personnel.
    
                                       20
<PAGE>
 
   
  The Codes require that all employees of the Manager preclear any personal
securities investment (with limited exceptions, such as government
securities). The preclearance requirement and associated procedures are
designed to identify any substantive prohibition or limitation applicable to
the proposed investment. The substantive restrictions applicable to all
employees of the Manager include a ban on acquiring any securities in a "hot"
initial public offering and a prohibition from profiting on short-term trading
in securities. In addition, no employee may purchase or sell any security
which at the time is being purchased or sold (as the case may be), or to the
knowledge of the employee is being considered for purchase or sale, by any
fund advised by the Manager. Furthermore, the Codes provide for trading
"blackout periods" which prohibit trading by investment personnel of the Fund
within periods of trading by the Fund in the same (or equivalent) security (15
or 30 days depending upon the transaction).     
 
TRANSFER AGENCY SERVICES
   
  Merrill Lynch Financial Data Services, Inc. (the "Transfer Agent"), which is
a wholly-owned subsidiary of ML&Co., acts as the Trust's transfer agent
pursuant to a transfer agency, dividend disbursing agency and shareholder
servicing agency agreement (the "Transfer Agency Agreement"). Pursuant to the
Transfer Agency Agreement, the Transfer Agent is responsible for the issuance,
transfer and redemption of shares and the opening and maintenance of
shareholder accounts. Pursuant to the Transfer Agency Agreement, the Fund pays
the Transfer Agent an annual fee of $11.00 per Class A or Class D shareholder
account and $14.00 per Class B and Class C shareholder account and the
Transfer Agent is entitled to reimbursement from the Fund for out-of-pocket
expenses incurred by the Transfer Agent under the Transfer Agency Agreement.
For the year ended July 31, 1995, the Fund paid the Transfer Agent a total fee
of $98,221 pursuant to the Transfer Agency Agreement for providing transfer
agency services. At September 30, 1995, the Fund had 645 Class A shareholder
accounts, 4,075 Class B shareholder accounts, 113 Class C shareholder accounts
and 55 Class D shareholder accounts. At this level of accounts, the annual fee
paid to the Transfer Agent would aggregate approximately $66,332, plus out-of-
pocket expenses.     
 
                              PURCHASE OF SHARES
   
  The Distributor, an affiliate of the Manager, MLAM and Merrill Lynch, acts
as the Distributor of the shares of the Fund. Shares of the Fund are offered
continuously for sale by the Distributor and other eligible securities dealers
(including Merrill Lynch). Shares of the Fund may be purchased from securities
dealers or by mailing a purchase order directly to the Transfer Agent. The
minimum initial purchase is $1,000 and the minimum subsequent purchase is $50.
       
  The Fund is offering its shares in four classes at a public offering price
equal to the next determined net asset value per share plus sales charges
imposed either at the time of purchase or on a deferred basis depending upon
the class of shares selected by the investor under the Merrill Lynch Select
Pricing (SM) System, as described below. The applicable offering price for
purchase orders is based upon the net asset value of the Fund next determined
after receipt of the purchase orders by the Distributor. As to purchase orders
received by securities dealers prior to the close of business on the New York
Stock Exchange (generally, 4:00 P.M., New York time), which includes orders
received after the close of business on the previous day, the applicable
offering price will be based on the net asset value determined as of 15
minutes after the close of business on the New York Stock Exchange on that
day, provided the Distributor in turn receives the order from the     
 
                                      21
<PAGE>
 
   
securities dealer prior to 30 minutes after the close of business on the New
York Stock Exchange on that day. If the purchase orders are not received by
the Distributor prior to 30 minutes after the close of business on the New
York Stock Exchange, such orders shall be deemed received on the next business
day. The Trust or the Distributor may suspend the continuous offering of the
Fund's shares of any class at any time in response to conditions in the
securities markets or otherwise and may thereafter resume such offering from
time to time. Any order may be rejected by the Distributor or the Trust.
Neither the Distributor nor the dealers are permitted to withhold placing
orders to benefit themselves by a price change. Merrill Lynch may charge its
customers a processing fee (presently $4.85) to confirm a sale of shares to
such customers. Purchases directly through the Fund's Transfer Agent are not
subject to the processing fee.     
   
  The Fund issues four classes of shares under the Merrill Lynch Select
Pricing (SM) System, which permits each investor to choose the method of
purchasing shares that the investor believes is most beneficial given the
amount of the purchase, the length of time the investor expects to hold the
shares and other relevant circumstances. Shares of Class A and Class D are
sold to investors choosing the initial sales charge alternatives and shares of
Class B and Class C are sold to investors choosing the deferred sales charge
alternatives. Investors should determine whether under their particular
circumstances it is more advantageous to incur an initial sales charge or to
have the entire initial purchase price invested in the Fund with the
investment thereafter being subject to a CDSC and ongoing distribution fees
and higher account maintenance fees. A discussion of the factors that
investors should consider in determining the method of purchasing shares under
the Merrill Lynch Select Pricing (SM) System is set forth under "Merrill Lynch
Select Pricing SM System" on page 4.     
 
  Each Class A, Class B, Class C and Class D share of the Fund represents
identical interests in the investment portfolio of the Fund and has the same
rights, except that Class B, Class C and Class D shares bear the expenses of
the ongoing account maintenance fees, and Class B and Class C shares bear the
expenses of the ongoing distribution fees and the additional incremental
transfer agency costs resulting from the deferred sales charge arrangements.
The deferred sales charges and account maintenance fees that are imposed on
Class B and Class C shares, as well as the account maintenance fees that are
imposed on Class D shares, will be imposed directly against those classes and
not against all assets of the Fund and, accordingly, such charges will not
affect the net asset value of any other class or have any impact on investors
choosing another sales charge option. Dividends paid by the Fund for each
class of shares will be calculated in the same manner at the same time and
will differ only to the extent that account maintenance and distribution fees
and any incremental transfer agency costs relating to a particular class are
borne exclusively by that class. Class B, Class C and Class D shares each have
exclusive voting rights with respect to the Rule 12b-1 distribution plan
adopted with respect to such class pursuant to which account maintenance
and/or distribution fees are paid. See "Distribution Plans" below. Each class
has different exchange privileges. See "Shareholder Services--Exchange
Privilege."
 
  Investors should understand that the purpose and function of the initial
sales charges with respect to Class A and Class D shares are the same as those
of the deferred sales charges with respect to Class B and Class C shares in
that the sales charges applicable to each class provide for the financing of
the distribution of the shares of the Fund. The distribution-related revenues
paid with respect to a class will not be used to finance the distribution
expenditures of another class. Sales personnel may receive different
compensation for selling different classes of shares. Investors are advised
that only Class A and Class D shares may be available for purchase through
securities dealers, other than Merrill Lynch, which are eligible to sell
shares.

(1) Initial sales charges are imposed at the time of purchase as a percentage
    of the offering price. CDSCs may be imposed if the redemption occurs
    within the applicable CDSC time period. The charge will be assessed on an
    amount equal to the lesser of the proceeds of redemption or the cost of
    the shares being redeemed.
(2) Offered only to eligible investors. See "Initial Sales Charge
    Alternatives--Class A and Class D Shares--Eligible Class A Investors."
   
(3) Reduced for purchases of $25,000 or more. Class A and Class D share
    purchases of $1,000,000 or more may not be subject to an initial sales
    charge but instead may be subject to a 1.0% CDSC if redeemed within one
    year.     
   
(4) The conversion period for dividend reinvestment shares was modified. Also,
    Class B shares of certain other MLAM-advised mutual funds into which
    exchanges may be made have an eight year conversion period. If Class B
    shares of the Fund are exchanged for Class B shares of another MLAM-
    advised mutual fund, the conversion period applicable to the Class B
    shares acquired in the exchange will apply, and the holding period for the
    shares exchanged will be tacked onto the holding period for the shares
    acquired.     
 
INITIAL SALES CHARGE ALTERNATIVES--CLASS A AND CLASS D SHARES
 
  Investors choosing the initial sales charge alternatives who are eligible to
purchase Class A shares should purchase Class A shares rather than Class D
shares because there is an account maintenance fee imposed on Class D shares.
 
  The public offering price of Class A and Class D shares for purchasers
choosing the initial sales charge alternative is the next determined net asset
value plus varying sales charges (i.e., sales loads), as set forth below.

 * Rounded to the nearest one-hundredth percent.     
   
** The initial sales charge may be waived on Class A and Class D purchases of
   $1,000,000 or more made on or after October 21, 1994 (the date Class D
   shares were initially offered to the public). If the sales charge is waived
   in connection with a purchase of $1,000,000 or more, such purchases will be
   subject to a CDSC of 1.0% if the shares are redeemed within one year after
   purchase.     
   
  The Distributor may reallow discounts to selected dealers and retain the
balance over such discounts. At times the Distributor may reallow the entire
sales charge to such dealers. Since securities dealers selling Class A and
Class D shares of the Fund will receive a concession equal to most of the
sales charge, they may be deemed to be underwriters under the Securities Act
of 1933, as amended. During the fiscal year ended July 31, 1995, the Fund sold
252,327 Class A shares for aggregate net proceeds of $2,701,007. The gross
sales charges for the sale of Class A shares of the Fund for that year were
$16,482, of which $1,289 and $15,193 were received by the Distributor and
Merrill Lynch, respectively. For the fiscal year ended July 31, 1995, the
Distributor received no CDSCs with respect to redemption within one year after
purchase of Class A shares purchased subject to front-end sales charge
waivers. For the period October 21, 1994 (commencement of operations) to July
31, 1995, the Fund sold 241,043 Class D shares for aggregate net proceeds of
$2,563,252. The gross sales charges for the sale of Class D shares of the Fund
for the period were $26,959, of which $773 and $26,186 were received by the
Distributor and Merrill Lynch, respectively. For the period October 21, 1994
(commencement of operations) to July 31, 1995, the Distributor received no
CDSCs with respect to redemption within one year after purchase of Class D
shares purchased subject to a front-end sales charge waiver.     
   
  Eligible Class A Investors. Class A shares are offered to a limited group of
investors and also will be issued upon reinvestment of dividends on
outstanding Class A shares. Investors that currently own Class A shares of the
Fund in a shareholder account are entitled to purchase additional Class A
shares of the Fund in that account. Class A shares are available at net asset
value to corporate warranty insurance reserve fund programs provided that the
program has $3 million or more initially invested in MLAM-advised mutual
funds. Also eligible to purchase Class A shares at net asset value are
participants in certain investment programs including TMA SM Managed Trusts to
which Merrill Lynch Trust Company provides discretionary trustee services and
certain purchases made in connection with the Merrill Lynch Mutual Fund
Adviser program. In addition, Class A shares are offered at net asset value to
ML & Co. and its subsidiaries and their directors and employees and to members
of the Boards of MLAM-advised investment companies, including the Trust.
Certain persons who acquired shares of certain MLAM-advised closed-end funds
who wish to reinvest the net proceeds from a sale of their closed-end fund
shares of common stock in shares of the Fund also may purchase Class A shares
of the Fund if certain conditions set forth in the Statement of Additional
Information are met. For example, Class A shares of the Fund and certain other
MLAM-advised mutual funds are offered at net asset value to shareholders of
Merrill Lynch Senior Floating Rate Fund, Inc. who wish to reinvest the net
proceeds from a sale of certain of their shares of common stock of Merrill
Lynch Senior Floating Rate Fund, Inc. in shares of such funds.     
 
  Reduced Initial Sales Charges. No initial sales charges are imposed upon
Class A and Class D shares issued as a result of the automatic reinvestment of
dividends or capital gains distributions. Class A and Class D sales charges
also may be reduced under a Right of Accumulation and a Letter of Intention.
 
  Class A shares are offered at net asset value to certain eligible Class A
investors as set forth above under "Eligible Class A Investors."
 
                                      24
<PAGE>
 
  Class D shares are offered at net asset value, without a sales charge, to an
investor who has a business relationship with a Merrill Lynch financial
consultant if certain conditions set forth in the Statement of Additional
Information are met. Class D shares may be offered at net asset value in
connection with the acquisition of assets of other investment companies.
   
  Class D shares of the Fund are offered at net asset value to shareholders of
Merrill Lynch Municipal Strategy Fund, Inc. who wish to reinvest the net
proceeds from a sale of certain of their shares of common stock of Merrill
Lynch Municipal Strategy Fund, Inc. in shares of the Fund.     
 
  Additional information concerning these reduced initial sales charges is set
forth in the Statement of Additional Information.
 
DEFERRED SALES CHARGE ALTERNATIVES--CLASS B AND CLASS C SHARES
 
  Investors choosing the deferred sales charge alternatives should consider
Class B shares if they intend to hold their shares for an extended period of
time and Class C shares if they are uncertain as to the length of time they
intend to hold their assets in MLAM-advised mutual funds.
 
  The public offering price of Class B and Class C shares for investors
choosing the deferred sales charge alternatives is the next determined net
asset value per share without the imposition of a sales charge at the time of
purchase. As discussed below, Class B shares are subject to a four year CDSC,
while Class C shares are subject only to a one year 1.0% CDSC. On the other
hand, approximately ten years after Class B shares are issued, such Class B
shares, together with shares issued upon dividend reinvestment with respect to
those shares, are automatically converted into Class D shares of the Fund and
thereafter will be subject to lower continuing fees. See "Conversion of Class B
Shares to Class D Shares" below. Both Class B and Class C shares are subject to
an account maintenance fee of 0.25% of net assets and Class B and Class C
shares are subject to distribution fees of 0.25% and 0.35%, respectively, of
net assets as discussed below under "Distribution Plans". The proceeds from the
account maintenance fees are used to compensate Merrill Lynch for providing
continuing account maintenance activities.
   
  Class B and Class C shares are sold without an initial sales charge so that
the Fund will receive the full amount of the investor's purchase payment.
Merrill Lynch compensates its financial consultants for selling Class B and
Class C shares at the time of purchase from its own funds. See "Distribution
Plans" on page 28.     
 
  Proceeds from the CDSCs and the distribution fee are paid to the Distributor
and are used in whole or in part by the Distributor to defray the expenses of
dealers (including Merrill Lynch) related to providing distribution-related
services to the Fund in connection with the sale of the Class B and Class C
shares, such as the payment of compensation to financial consultants for
selling Class B and Class C shares from the dealer's own funds. The combination
of the CDSC and the ongoing distribution fee facilitates the ability of the
Fund to sell the Class B and Class C shares without a sales charge being
deducted at the time of purchase. Approximately ten years after issuance, Class
B shares will convert automatically into Class D shares of the Fund, which are
subject to a lower account maintenance fee and no distribution fee; Class B
shares of certain other MLAM-advised mutual funds into which exchanges may be
made convert into Class D shares automatically after approximately eight years.
If Class B shares of the Fund are exchanged for Class B shares of another MLAM-
advised mutual fund, the conversion period applicable to the Class B shares
acquired in
 
                                       25
<PAGE>
 
the exchange will apply, and the holding period for the shares exchanged will
be tacked onto the holding period for the shares acquired.
 
  Imposition of the CDSC and the distribution fee on Class B and Class C shares
is limited by the NASD asset-based sales charge rule. See "Limitations on the
Payment of Deferred Sales Charges" below. The proceeds from the ongoing account
maintenance fee are used to compensate Merrill Lynch for providing continuing
account maintenance activities. Class B shareholders of the Fund exercising the
exchange privilege described under "Shareholder Services--Exchange Privilege"
will continue to be subject to the Fund's CDSC schedule, if such schedule is
higher than the CDSC schedule relating to the Class B shares acquired as a
result of the exchange.
   
  Contingent Deferred Sales Charges--Class B Shares. Class B shares which are
redeemed within four years of purchase may be subject to a CDSC at the rates
set forth below charged as a percentage of the dollar amount subject thereto.
The charge will be assessed on an amount equal to the lesser of the proceeds of
redemption or the cost of the shares being redeemed. Accordingly, no CDSC will
be imposed on increases in net asset value above the initial purchase price. In
addition, no CDSC will be assessed on shares derived from reinvestment of
dividends or capital gains distributions.     
 
  The following table sets forth the rates of the Class B CDSC:

  For the fiscal year ended July 31, 1995, the Distributor received CDSCs of
$302,369 with respect to redemptions of Class B shares, all of which were paid
to Merrill Lynch.     
 
  In determining whether a CDSC is applicable to a redemption, the calculation
will be determined in the manner that results in the lowest possible applicable
rate being charged. Therefore, it will be assumed that the redemption is first
of shares held for over four years or shares acquired pursuant to reinvestment
of dividends or distributions and then of shares held longest during the four-
year period. The charge will not be applied to dollar amounts representing an
increase in the net asset value since the time of purchase. A transfer of
shares from a shareholder's account to another account will be assumed to be
made in the same order as a redemption.
   
  To provide an example, assume an investor purchased 100 Class B shares at $10
per share (at a cost of $1,000) and in the third year after purchase, the net
asset value per share is $12 and, during such time, the investor has acquired
10 additional shares upon dividend reinvestment. If at such time the investor
makes his first redemption of 50 shares (proceeds of $600), 10 shares will not
be subject to a CDSC because of dividend reinvestment. With respect to the
remaining 40 shares, the CDSC is applied only to the original cost of $10     
 
                                       26
<PAGE>
 
per share and not to the increase in net asset value of $2 per share.
Therefore, $400 of the $600 redemption proceeds will be charged at a rate of
2.0% (the applicable rates in the third year after purchase).
   
  In the event that Class B shares are exchanged by certain retirement plans
for Class A shares in connection with a transfer to the Merrill Lynch Mutual
Fund Adviser ("MFA") program, the time period that such Class A shares are held
in the MFA program will be included in determining the holding period of Class
B shares reacquired upon termination of participation in the MFA program (see
"Shareholder Services--Exchange Privilege").     
 
  The Class B CDSC is waived on redemptions of shares following the death or
disability (as defined in the Code) of a shareholder. Additional information
concerning the waiver of the Class B CDSC is set forth in the Statement of
Additional Information.
   
  Contingent Deferred Sales Charges--Class C Shares. Class C shares which are
redeemed within one year of purchase may be subject to a 1.0% CDSC charged as a
percentage of the dollar amount subject thereto. The charge will be assessed on
an amount equal to the lesser of the proceeds of redemption or the cost of the
shares being redeemed. Accordingly, no Class C CDSC will be imposed on
increases in net asset value above the initial purchase price. In addition, no
Class C CDSC will be assessed on shares derived from reinvestment of dividends
or capital gains distributions. For the period October 21, 1994 (commencement
of operations) to July 31, 1995, the Distributor received CDSCs of $621 with
respect to redemptions of Class C shares, all of which were paid to Merrill
Lynch.     
 
  In determining whether a Class C CDSC is applicable to a redemption, the
calculation will be determined in the manner that results in the lowest
possible rate being charged. Therefore, it will be assumed that the redemption
is first of shares held for over one year or shares acquired pursuant to
reinvestment of dividends or distributions and then of shares held longest
during the one-year period. The charge will not be applied to dollar amounts
representing an increase in the net asset value since the time of purchase. A
transfer of shares from a shareholder's account to another account will be
assumed to be made in the same order as a redemption.
 
  Conversion of Class B Shares to Class D Shares. After approximately ten years
(the "Conversion Period"), Class B shares also will be converted automatically
into Class D shares of the Fund. Class D shares are subject to an ongoing
account maintenance fee of 0.10% of net assets but are not subject to the
distribution fee that is borne by Class B shares. Automatic conversion of Class
B shares into Class D shares will occur at least once each month (on the
"Conversion Date") on the basis of the relative net asset values of the shares
of the two classes on the Conversion Date, without the imposition of any sales
load, fee or other charge. Conversion of Class B shares to Class D shares will
not be deemed a purchase or sale of the shares for Federal income tax purposes.
 
  In addition, shares purchased through reinvestment of dividends on Class B
shares also will convert automatically to Class D shares. The Conversion Date
for dividend reinvestment shares will be calculated taking into account the
length of time the shares underlying such dividend reinvestment shares were
outstanding. If at a Conversion Date the conversion of Class B shares to Class
D shares of the Fund in a single account will result in less than $50 worth of
Class B shares being left in the account, all of the Class B shares of the Fund
held in the account on the Conversion Date will be converted to Class D shares
of the Fund.
 
 
                                       27
<PAGE>
 
       
  Share certificates for Class B shares of the Fund to be converted must be
delivered to the Transfer Agent at least one week prior to the Conversion Date
applicable to those shares. In the event such certificates are not received by
the Transfer Agent at least one week prior to the Conversion Date, the related
Class B shares will convert to Class D shares on the next scheduled Conversion
Date after such certificates are delivered.
 
  In general, Class B shares of equity MLAM-advised mutual funds will convert
approximately eight years after initial purchase, and Class B shares of taxable
and tax-exempt fixed income MLAM-advised mutual funds will convert
approximately ten years after initial purchase. If, during the Conversion
Period, a shareholder exchanges Class B shares with an eight-year Conversion
Period for Class B shares with a ten-year Conversion Period, or vice versa, the
Conversion Period applicable to the Class B shares acquired in the exchange
will apply, and the holding period for the shares exchanged will be tacked onto
the holding period for the shares acquired.
 
DISTRIBUTION PLANS
 
  The Fund has adopted separate distribution plans for Class B, Class C and
Class D shares pursuant to Rule 12b-1 under the Investment Company Act (each, a
"Distribution Plan") with respect to the account maintenance and/or
distribution fees paid by the Fund to the Distributor with respect to such
classes. The Class B and Class C Distribution Plans provide for the payment of
account maintenance fees and distribution fees, and the Class D Distribution
Plan provides for the payment of account maintenance fees.
 
  The Distribution Plans for Class B, Class C and Class D shares each provide
that the Fund pays the Distributor an account maintenance fee relating to the
shares of the relevant class, accrued daily and paid monthly, at the annual
rates of 0.25%, 0.25% and 0.10%, respectively, of the average daily net assets
of the Fund attributable to shares of the relevant class in order to compensate
the Distributor and Merrill Lynch (pursuant to a sub-agreement) in connection
with account maintenance activities.
   
  The Distribution Plans for Class B and Class C shares each provide that the
Fund also pays the Distributor a distribution fee relating to the shares of the
relevant class, accrued daily and paid monthly, at the annual rate of 0.25% and
0.35%, respectively, of the average daily net assets of the Fund attributable
to the shares of the relevant class in order to compensate the Distributor and
Merrill Lynch (pursuant to a sub-agreement) for providing shareholder and
distribution services, and bearing certain distribution-related expenses of the
Fund, including payments to financial consultants for selling Class B and Class
C shares of the Fund. The Distribution Plans relating to Class B and Class C
shares are designed to permit an investor to purchase Class B and Class C
shares through dealers without the assessment of an initial sales charge and at
the same time permit the dealer to compensate its financial consultants in
connection with the sale of the Class B and Class C shares. In this regard, the
purpose and function of the ongoing distribution fees and the CDSC are the same
as those of the initial sales charge with respect to the Class A and Class D
shares of the Fund in that the deferred sales charges provide for the financing
of the distribution of the Fund's Class B and Class C shares.     
   
  For the fiscal year ended July 31, 1995, the Fund paid the Distributor
$618,190 pursuant to the Class B Distribution Plan (based on average net assets
subject to such Distribution Plan of approximately $123.6 million), all of
which was paid to Merrill Lynch for providing account maintenance and
distribution-related activities and services in connection with Class B shares.
During the period October 21, 1994 (commencement     
 
                                       28
<PAGE>
 
   
of operations) to July 31, 1995, the Fund paid the Distributor $4,335 pursuant
to the Distribution Plan relating to Class C shares (based on average net
assets subject to such Distribution Plan of approximately $938,519), all of
which was paid to Merrill Lynch for providing account maintenance and
distribution-related activities and services in connection with Class C shares.
During the fiscal period October 21, 1994 (commencement of operations) to July
31, 1995, the Fund paid the Distributor $1,586 pursuant to the Distribution
Plan relating to Class D shares (based on average net assets subject to such
Distribution Plan of approximately $2.1 million), all of which was paid to
Merrill Lynch for providing account maintenance services in connection with
Class D shares. At September 30, 1995, the net assets of the Fund subject to
the Class B Distribution Plan aggregated approximately $123.7 million. At this
asset level, the annual fee payable pursuant to the Class B Distribution Plan
would aggregate approximately $618,657. At September 30, 1995, the net assets
of the Fund subject to the Class C Distribution Plan aggregated approximately
$2.7 million. At this asset level, the annual fee payable pursuant to the Class
C Distribution Plan would aggregate approximately $16,397. At September 30,
1995, the net assets of the Fund subject to the Class D Distribution Plan
aggregated approximately $2.7 million. At this asset level, the annual fee
payable pursuant to the Class D Distribution Plan would aggregate approximately
$2,703.     
          
  The payments under the Distribution Plan are based on a percentage of average
daily net assets attributable to the shares regardless of the amount of
expenses incurred and, accordingly, distribution-related revenues from the
Distribution Plans may be more or less than distribution-related expenses.
Information with respect to the distribution-related revenues and expenses is
presented to the Trustees for their consideration in connection with their
deliberations as to the continuance of the Class B and Class C Distribution
Plans. This information is presented annually as of December 31 of each year on
a "fully allocated accrual" basis and quarterly on a "direct expense and
revenue/cash" basis. On the fully allocated accrual basis, revenues consist of
the account maintenance fees, distribution fees, the CDSCs and certain other
related revenues, and expenses consist of financial consultant compensation,
branch office and regional operation center selling and transaction processing
expenses, advertising, sales promotion and marketing expenses, corporate
overhead and interest expense. On the direct expense and revenue/cash basis,
revenues consist of the account maintenance fees, distribution fees and CDSCs
and the expenses consist of financial consultant compensation. As of December
31, 1994, for Class B shares, the fully allocated accrual revenues incurred by
the Distributor and Merrill Lynch exceeded fully allocated accrual expenses for
such period by approximately $2,260,000 (1.93% of Class B net assets at that
date). As of July 31, 1995, direct cash revenues for the period since the
commencement of operations of Class B shares exceeded direct cash expenses by
approximately $502,115 (.43% of Class B net assets at that date). As of July
31, 1995, for Class C shares, direct cash expenses for the period since
commencement of operations of Class C shares exceeded direct cash revenues by
$3,200 (0.86% of Class C net assets at that date).     
 
  The Fund has no obligation with respect to distribution and/or account
maintenance-related expenses incurred by the Distributor and Merrill Lynch in
connection with Class B, Class C and Class D shares, and there is no assurance
that the Trustees of the Trust will approve the continuance of the Distribution
Plans from year to year. However, the Distributor intends to seek annual
continuation of the Distribution Plans. In their review of the Distribution
Plans, the Trustees will be asked to take into consideration expenses incurred
in connection with the account maintenance and/or distribution of each class of
shares separately. The initial sales charges, the account maintenance fee, the
distribution fee and/or the CDSCs received with respect to one class will not
be used to subsidize the sale of shares of another class. Payments of the
distribution fee on
 
                                       29
<PAGE>
 
Class B shares will terminate upon conversion of those Class B shares into
Class D shares as set forth under "Deferred Sales Charge Alternatives--Class B
and Class C Shares--Conversion of Class B Shares to Class D Shares."
 
LIMITATIONS ON THE PAYMENT OF DEFERRED SALES CHARGES
 
  The maximum sales charge rule in the Rules of Fair Practice of the NASD
imposes a limitation on certain asset-based sales charges such as the
distribution fee and the CDSC borne by the Class B and the Class C shares, but
not the account maintenance fee. The maximum sales charge rule is applied
separately to each class. As applicable to the Fund, the maximum sales charge
rule limits the aggregate of distribution fee payments and CDSCs payable by the
Fund to (1) 6.25% of eligible gross sales of Class B shares and Class C shares,
computed separately (defined to exclude shares issued pursuant to dividend
reinvestments and exchanges) plus (2) interest on the unpaid balance for the
respective class, computed separately at the prime rate plus 1% (the unpaid
balance being the maximum amount payable minus amounts received from the
payment of the distribution fee and the CDSC). In connection with the Class B
shares, the Distributor has voluntarily agreed to waive interest charges on the
unpaid balance in excess of 0.50% of eligible gross sales. Consequently, the
maximum amount payable to the Distributor (referred to as the "voluntary
maximum") in connection with the Class B shares is 6.75% of eligible gross
sales. The Distributor retains the right to stop waiving the interest charges
at any time. To the extent payments would exceed the voluntary maximum, the
Fund will not make further payments of the distribution fee with respect to
Class B shares and any CDSCs will be paid to the Fund rather than to the
Distributor; however, the Fund will continue to make payments of the account
maintenance fee. In certain circumstances the amount payable pursuant to the
voluntary maximum may exceed the amount payable under the NASD formula. In such
circumstances payments in excess of the amount payable under the NASD formula
will not be made.
 
                              REDEMPTION OF SHARES
 
  The Trust is required to redeem for cash all shares of the Fund upon receipt
of a written request in proper form. The redemption price is the net asset
value per share next determined after the initial receipt of proper notice of
redemption. Except for any CDSC which may be applicable, there will be no
charge for redemption if the redemption request is sent directly to the
Transfer Agent. Shareholders liquidating their holdings will receive upon
redemption all dividends reinvested through the date of redemption. The value
of shares at the time of redemption may be more or less than the shareholder's
cost, depending on the market value of the securities held by the Fund at such
time.
 
REDEMPTION
   
  A shareholder wishing to redeem shares may do so without charge by tendering
the shares directly to the Transfer Agent, Merrill Lynch Financial Data
Services, Inc., P.O. Box 45289, Jacksonville, Florida 32232-5289. Redemption
requests delivered other than by mail should be delivered to Merrill Lynch
Financial Data Services, Inc., 4800 Deer Lake Drive East, Jacksonville, Florida
32246-6484. Proper notice of redemption in the case of shares deposited with
the Transfer Agent may be accomplished by a written letter requesting
redemption. Proper notice of redemption in the case of shares for which
certificates have been issued may be accomplished by a written letter as noted
above accompanied by certificates for the shares     
 
                                       30
<PAGE>
 
to be redeemed. Redemption requests should not be sent to the Trust. The notice
in either event requires the signature(s) of all persons in whose name(s) the
shares are registered, signed exactly as such name(s) appear(s) on the Transfer
Agent's register. The signature(s) on the redemption request must be guaranteed
by an "eligible guarantor institution" as such is defined in Rule 17Ad-15 under
the Securities Exchange Act of 1934, as amended, the existence and validity of
which may be verified by the Transfer Agent through the use of industry
publications. Notarized signatures are not sufficient. In certain instances,
the Transfer Agent may require additional documents such as, but not limited
to, trust instruments, death certificates, appointments as executor or
administrator, or certificates of corporate authority. For shareholders
redeeming directly with the Transfer Agent, payments will be mailed within
seven days of receipt of a proper notice of redemption.
 
  At various times the Trust may be requested to redeem Fund shares for which
it has not yet received good payment (e.g., cash, Federal funds or certified
check drawn on a United States bank). The Trust may delay or cause to be
delayed the mailing of a redemption check until such time as it has assured
itself that good payment has been collected for the purchase of such Fund
shares, which will not exceed 10 days.
 
REPURCHASE
   
  The Trust also will repurchase Fund shares through a shareholder's listed
securities dealer. The Trust normally will accept orders to repurchase Fund
shares by wire or telephone from dealers for their customers at the net asset
value next computed after receipt of the order by the dealer, provided that the
request for repurchase is received by the dealer prior to the close of business
on the New York Stock Exchange (generally, 4:00 P.M., New York time) on the day
received, and such request is received by the Trust from such dealer not later
than 30 minutes after the close of business on the New York Stock Exchange on
the same day. Dealers have the responsibility of submitting such repurchase
requests to the Fund not later than 30 minutes after the close of business on
the New York Stock Exchange, in order to obtain that day's closing price.     
 
  The foregoing repurchase arrangements are for the convenience of shareholders
and do not involve a charge by the Trust (other than any applicable CDSC).
Securities firms which do not have selected dealer agreements with the
Distributor, however, may impose a transaction charge on the shareholder for
transmitting the notice of repurchase to the Trust. Merrill Lynch may charge
its customers a processing fee (presently $4.85) to confirm a repurchase of
shares of such customers. Redemptions directly through the Fund's Transfer
Agent are not subject to the processing fee. The Trust reserves the right to
reject any order for repurchase, which right of rejection might adversely
affect shareholders seeking redemption through the repurchase procedure.
However, a shareholder whose order for repurchase is rejected by the Trust may
redeem Fund shares as set forth above.
 
REINSTATEMENT PRIVILEGE--CLASS A AND CLASS D SHARES
 
  Shareholders who have redeemed their Class A or Class D shares have a one-
time privilege to reinstate their accounts by purchasing Class A or Class D
shares, as the case may be, of the Fund at net asset value without a sales
charge up to the dollar amount redeemed. The reinstatement privilege may be
exercised by sending a notice of exercise along with a check for the amount to
be reinstated to the Transfer Agent within 30 days after the date the request
for redemption was accepted by the Transfer Agent or the Distributor. The
reinstatement will be made at the net asset value per share next determined
after the notice of reinstatement is received and cannot exceed the amount of
the redemption proceeds. The reinstatement privilege is a one-
 
                                       31
<PAGE>
 
time privilege and may be exercised by the Class A or Class D shareholder only
the first time such shareholder makes a redemption.
 
                             SHAREHOLDER SERVICES
 
  The Trust offers a number of shareholder services and investment plans
designed to facilitate investment in shares of the Fund. Full details as to
each of such services, copies of the various plans described below and
instructions as to how to participate in the various services or plans, or to
change options with respect thereto can be obtained from the Trust by calling
the telephone number on the cover page hereof or from the Distributor or
Merrill Lynch.
   
  Investment Account. Each shareholder whose account (an "Investment Account")
is maintained at the Transfer Agent has an Investment Account and will receive
statements at least quarterly from the Transfer Agent. These statements will
serve as transaction confirmations for automatic investment purchases and the
reinvestment of ordinary income dividends and long-term capital gain
distributions. The statements will also show any other activity in the account
since the preceding statement. Shareholders will receive separate
confirmations for each purchase or sale transaction other than automatic
investment purchases and the reinvestment of ordinary income dividends and
long-term capital gains distributions. A shareholder may make additions to his
Investment Account at any time by mailing a check directly to the Transfer
Agent. Shareholders may also maintain their accounts through Merrill Lynch.
Upon the transfer of shares out of a Merrill Lynch brokerage account, an
Investment Account in the transferring shareholder's name will be opened
automatically at the Transfer Agent. Shareholders considering transferring
their Class A or Class D shares from Merrill Lynch to another brokerage firm
or financial institution should be aware that, if the firm to which the Class
A or Class D shares are to be transferred will not take delivery of shares of
the Fund, a shareholder either must redeem the Class A or Class D shares
(paying any applicable CDSC) so that the cash proceeds can be transferred to
the account at the new firm or such shareholder must continue to maintain an
Investment Account at the Transfer Agent for those Class A or Class D shares.
Shareholders interested in transferring their Class B or Class C shares from
Merrill Lynch and who do not wish to have an Investment Account maintained for
such shares at the Transfer Agent may request their new brokerage firm to
maintain such shares in an account registered in the name of the brokerage
firm for the benefit of the shareholder at the Transfer Agent.     
 
  Exchange Privilege. Shareholders of each class of shares of the Fund each
have an exchange privilege with certain other MLAM-advised mutual funds. There
is currently no limitation on the number of times a shareholder may exercise
the exchange privilege. The exchange privilege may be modified or terminated
at any time in accordance with the rules of the Commission.
 
  Under the Merrill Lynch Select Pricing (SM) System, Class A shareholders may
exchange Class A shares of the Fund for Class A shares of a second MLAM-
advised mutual fund if the shareholder holds any Class A shares of the second
fund in his account in which the exchange is made at the time of the exchange
or is otherwise eligible to purchase Class A shares of the second fund. If the
Class A shareholder wants to exchange Class A shares for shares of a second
MLAM-advised mutual fund, and the shareholder does not hold Class A shares of
the second fund in his account at the time of the exchange and is not
otherwise eligible to acquire Class A shares of the second fund, the
shareholder will receive Class D shares of the second fund as a result
 
                                      32
<PAGE>
 
of the exchange. Class D shares also may be exchanged for Class A shares of a
second MLAM-advised mutual fund at any time as long as, at the time of the
exchange, the shareholder holds Class A shares of the second fund in the
account in which the exchange is made or is otherwise eligible to purchase
Class A shares of the second fund.
 
  Exchanges of Class A and Class D shares are made on the basis of the relative
net asset values per Class A or Class D share, respectively, plus an amount
equal to the difference, if any, between the sales charge previously paid on
the Class A or Class D shares being exchanged and the sales charge payable at
the time of the exchange on the shares being acquired.
   
  Class B, Class C and Class D shares are exchangeable with shares of the same
class of other MLAM-advised mutual funds.     
   
  Shares of the Fund which are subject to a CDSC are exchangeable on the basis
of relative net asset value per share without the payment of any CDSC that
might otherwise be due upon redemption of the shares of the Fund. For purposes
of computing the CDSC that may be payable upon a disposition of the shares
acquired in the exchange, the holding period for the previously owned shares of
the Fund is "tacked" to the holding period of the newly acquired shares of the
other Fund.     
   
  Class A, Class B, Class C and Class D shares also are exchangeable for shares
of certain MLAM-advised money market funds specifically designated as available
for exchange by holders of Class A, Class B, Class C or Class D shares. The
period of time that Class A, Class B, Class C or Class D shares are held in a
money market fund, however, will not count toward satisfaction of the holding
period requirement for reduction of any CDSC imposed on such shares, if any,
and, with respect to Class B shares, toward satisfaction of the Conversion
Period.     
 
  Class B shareholders of the Fund exercising the exchange privilege will
continue to be subject to the Fund's CDSC schedule if such schedule is higher
than the CDSC schedule relating to the new Class B shares. In addition, Class B
shares of the Fund acquired through use of the exchange privilege will be
subject to the Fund's CDSC schedule if such schedule is higher than the CDSC
schedule relating to the Class B shares of the MLAM-advised mutual fund from
which the exchange has been made.
 
  Exercise of the exchange privilege is treated as a sale for Federal income
tax purposes. For further information, see "Shareholder Services--Exchange
Privilege" in the Statement of Additional Information.
   
  The Fund's exchange privilege is modified with respect to purchases of Class
A and Class D shares by non-retirement plan investors under the MFA program.
First, the initial allocation of assets is made under the MFA program. Then,
any subsequent exchange under the MFA program of Class A or Class D shares of a
MLAM-advised mutual fund for Class A or Class D shares of the Fund will be made
solely on the basis of the relative net asset values of the shares being
exchanged. Therefore, there will not be a charge for any difference between the
sales charge previously paid on the shares of the other MLAM-advised mutual
funds and the sales charge payable on the shares of the Fund being acquired in
the exchange under the MFA program.     
 
  Automatic Reinvestment of Dividends and Capital Gains Distributions. All
dividends and capital gains distributions are reinvested automatically in full
and fractional shares of the Fund, without a sales charge, at
 
                                       33
<PAGE>
 
the net asset value per share at the close of business on the monthly payment
date for such dividends and distributions. A shareholder may at any time, by
written notification or by telephone (1-800-MER-FUND) to the Transfer Agent,
elect to have subsequent dividends or both dividends and capital gains
distributions paid in cash, rather than reinvested, in which event payment will
be mailed or directly deposited monthly. Cash payments can also be directly
deposited to the shareholder's bank account. No CDSC will be imposed upon
redemption of shares issued as a result of the automatic reinvestment of
dividends or capital gains distributions.
   
  Systematic Withdrawal Plans. A Class A or Class D shareholder may elect to
receive systematic withdrawal payments from his Investment Account through
automatic payment by check or through automatic payment by direct deposit to
his bank account on either a monthly or quarterly basis. Alternatively, a Class
A or Class D shareholder whose shares are held within a CMA (R) or CBA (R)
account may elect to have shares redeemed on a monthly, bimonthly, quarterly,
semiannual or annual basis through the CMA (R)/CBA (R) Systematic Redemption
Program, subject to certain conditions.     
   
  Automatic Investment Plans. Regular additions of Class A, Class B, Class C or
Class D shares may be made to an investor's Investment Account by pre-arranged
charges of $50 or more to his or her regular bank account. The Fund's Automatic
Investment Program is not available to shareholders whose shares are held in a
brokerage account with Merrill Lynch. Alternatively, investors who maintain
CMA (R) or CBA (R) accounts may arrange to have periodic investments made in
the Fund in their CMA (R) or CBA (R) account or in certain related accounts in
amounts of $100 or more through the CMA (R)/CBA (R) Automated Investment
Program.     
 
                             PORTFOLIO TRANSACTIONS
 
  The Trust has no obligation to deal with any dealer or group of dealers in
the execution of transactions in portfolio securities of the Fund. Municipal
Bonds and other securities in which the Fund invests are traded primarily in
the over-the-counter market. Where possible, the Trust deals directly with the
dealers who make a market in the securities involved except in those
circumstances where better prices and execution are available elsewhere. It is
the policy of the Trust to obtain the best net results in conducting portfolio
transactions for the Fund, taking into account such factors as price (including
the applicable dealer spread), the size, type and difficulty of the
transactions involved, the firm's general execution and operations facilities,
and the firm's risk in positioning the securities involved and the provision of
supplemental investment research by the firm. While reasonably competitive
spreads or commissions are sought, the Fund will not necessarily be paying the
lowest spread or commission available. The sale of shares of the Fund may be
taken into consideration as a factor in the selection of brokers and dealers to
execute portfolio transactions for the Fund. The portfolio securities of the
Fund generally are traded on a net basis and normally do not involve either
brokerage commissions or transfer taxes. The cost of portfolio securities
transactions of the Fund primarily consists of dealer or underwriter spreads.
Under the 1940 Act, persons affiliated with the Trust, including Merrill Lynch,
are prohibited from dealing with the Trust as a principal in the purchase and
sale of securities unless such trading is permitted by an exemptive order
issued by the Commission. The Trust has obtained an exemptive order permitting
it to engage in certain principal transactions with Merrill Lynch involving
high quality short-term municipal bonds subject to certain conditions. In
addition, the Trust may not purchase securities, including Municipal Bonds, for
the Fund during the existence of any underwriting syndicate of which Merrill
Lynch is a member except pursuant to procedures approved by the Trustees of
 
                                       34
<PAGE>
 
   
the Trust which comply with rules adopted by the Commission. The Trust has
applied for an exemptive order permitting it to, among other things, (i)
purchase high quality tax-exempt securities from Merrill Lynch when Merrill
Lynch is a member of an underwriting syndicate and (ii) purchase tax-exempt
securities from and sell tax-exempt securities to Merrill Lynch in secondary
market transactions. Affiliated persons of the Trust may serve as its broker in
over-the-counter transactions conducted for the Fund on an agency basis only.
    
                            DISTRIBUTIONS AND TAXES
 
DISTRIBUTIONS
   
  The net investment income of the Fund is declared as dividends daily prior to
the determination of the net asset value which is calculated 15 minutes after
the close of business on the New York Stock Exchange (generally, 4:00 P.M., New
York time) on that day. The net investment income of the Fund for dividend
purposes consists of interest earned on portfolio securities, less expenses, in
each case computed since the most recent determination of the net asset value.
Expenses of the Fund, including the management fees and the account maintenance
and distribution fees, are accrued daily. Dividends of net investment income
are declared daily and reinvested monthly in the form of additional full and
fractional shares of the Fund at net asset value as of the close of business on
the payment date unless the shareholder elects to receive such dividends in
cash. Shares will accrue dividends as long as they are issued and outstanding.
Shares are issued and outstanding from the settlement date of a purchase order
to the day prior to the settlement date of a redemption order.     
 
  All net realized long- or short-term capital gains, if any, are declared and
distributed to the Fund's shareholders annually. Capital gains distributions
will be reinvested automatically in shares unless the shareholder elects to
receive such distributions in cash.
   
  The per share dividends and distributions on each Class of shares will be
reduced as a result of any account maintenance, distribution and transfer
agency fees applicable to that class. See "Additional Information--
Determination of Net Asset Value".     
 
  See "Shareholder Services" for information as to how to elect either dividend
reinvestment or cash payments. Portions of dividends and distributions which
are taxable to shareholders as described below are subject to income tax
whether they are reinvested in shares of the Fund or received in cash.
 
TAXES
 
  The Trust intends to continue to qualify the Fund for the special tax
treatment afforded regulated investment companies ("RICs") under the Internal
Revenue Code of 1986, as amended (the "Code"). If it so qualifies, in any
taxable year in which it distributes at least 90% of its taxable net income and
90% of its tax-exempt net income (see below), the Fund (but not its
shareholders) will not be subject to Federal income tax to the extent that it
distributes its net investment income and net realized capital gains. The Trust
intends to cause the Fund to distribute substantially all of such income.
   
  To the extent that the dividends distributed to the Fund's Class A, Class B,
Class C and Class D shareholders (together, the "shareholders") are derived
from interest income exempt from Federal income     
 
                                       35
<PAGE>
 
   
tax under Code Section 103(a) and are properly designated as "exempt-interest
dividends" by the Trust, they will be excludable from a shareholder's gross
income for Federal income tax purposes. Exempt-interest dividends are included,
however, in determining the portion, if any, of a person's social security
benefits and railroad retirement benefits subject to Federal income taxes. The
portion of exempt-interest dividends paid from interest received by the Fund
from Pennsylvania Municipal Bonds also will be exempt from Pennsylvania
personal income tax. However, distributions attributable to capital gains
derived by the Fund as well as distributions derived from income from
investments other than Pennsylvania Municipal Bonds will be taxable for
Pennsylvania personal income tax purposes. In the case of residents of the City
of Philadelphia, distributions which are derived from interest received by the
Fund from Pennsylvania Municipal Bonds or which are designated as capital gain
dividends for Federal income tax purposes will be exempt from the Philadelphia
School District investment income tax. Shareholders subject to income taxation
by states other than Pennsylvania will realize a lower after-tax rate of return
than Pennsylvania shareholders since the dividends distributed by the Fund
generally will not be exempt, to any significant degree, from income taxation
by such other states. The Trust will inform shareholders annually as to the
portion of the distributions which constitutes exempt-interest dividends and
the portion which is exempt from Pennsylvania personal income taxes. Interest
on indebtedness incurred or continued to purchase or carry Fund shares is not
deductible for Federal income tax purposes to the extent attributable to
exempt-interest dividends. Persons who may be "substantial users" (or "related
persons" of substantial users) of facilities financed by industrial development
bonds or private activity bonds held by the Fund should consult their tax
advisers before purchasing Fund shares.     
 
  It is unclear at this time whether an investment in the Fund by a corporate
shareholder will qualify as an exempt asset for purposes of apportionment of
the Pennsylvania capital stock/foreign franchise tax. To the extent exempt-
interest dividends are excluded from taxable income for Federal corporate
income tax purposes (determined before net operating loss carryovers and
special deductions), they will not be subject to the Pennsylvania corporate net
income tax.
   
  Shares of the Fund will be exempt from Pennsylvania county personal property
taxes to the extent the Fund's portfolio securities consist of Pennsylvania
Municipal Bonds on the annual assessment date.     
   
  To the extent that the Fund's distributions are derived from interest on its
taxable investments or from an excess of net short-term capital gains over net
long-term capital losses ("ordinary income dividends") such distributions are
considered ordinary income for Federal income tax purposes. Distributions, if
any, from the excess of net long-term capital gains over net short-term capital
losses derived from the sale of securities or from certain transactions in
futures or options ("capital gain dividends") are taxable as long-term capital
gains for Federal income tax purposes, regardless of the length of time the
shareholder has owned Fund shares. Distributions by the Fund, whether from
exempt-interest income, ordinary income or capital gains, will not be eligible
for the dividends received deduction allowed to corporations under the Code.
       
  All or a portion of the Fund's gain from the sale or redemption of tax-exempt
obligations purchased at a market discount will be treated as ordinary income
rather than capital gain. This rule may increase the amount of ordinary income
dividends received by shareholders. Distributions in excess of the Fund's
earnings and profits will first reduce the adjusted tax basis of a holder's
shares and, after such adjusted tax basis is reduced to zero, will constitute
capital gains to such holder (assuming the shares are held as a capital asset).
Any loss upon the sale or exchange of Fund shares held for six months or less
will be treated as long-term     
 
                                       36
<PAGE>
 
capital loss to the extent of any capital gain dividends received by the
shareholder. In addition, such loss will be disallowed to the extent of any
exempt-interest dividends received by the shareholder. If the Fund pays a
dividend in January which was declared in the previous October, November or
December to shareholders of record on a specified date in one of such months,
then such dividend will be treated for tax purposes as being paid by the Fund
and received by its shareholders on December 31 of the year in which such
dividend was declared.
   
  The Code subjects interest received on certain otherwise tax-exempt
securities to an alternative minimum tax. The alternative minimum tax applies
to interest received on "private activity bonds" issued after August 7, 1986.
Private activity bonds are bonds which, although tax-exempt, are used for
purposes other than those generally performed by governmental units and which
benefit non-governmental entities (e.g., bonds used for industrial development
or housing purposes). Income received on such bonds is classified as an item of
"tax preference", which could subject investors in such bonds, including
shareholders of the Fund, to an alternative minimum tax. The Fund will purchase
such "private activity bonds" and the Trust will report to shareholders within
60 days after the Fund's taxable year-end the portion of its dividends declared
during the year which constitutes an item of tax preference for alternative
minimum tax purposes. The Code further provides that corporations are subject
to an alternative minimum tax based, in part, on certain differences between
taxable income as adjusted for other tax preferences and "adjusted current
earnings," which more closely reflect a corporation's economic income. Because
an exempt-interest dividend paid by the Fund will be included in adjusted
current earnings, a corporate shareholder may be required to pay alternative
minimum tax on exempt-interest dividends paid by the Fund.     
          
  No gain or loss will be recognized for Federal income tax purposes by Class B
shareholders on the conversion of their Class B shares into Class D shares. A
shareholder's basis in the Class D shares acquired will be the same as such
shareholder's basis in the Class B shares converted, and the holding period of
the acquired Class D shares will include the holding period for the converted
Class B shares.     
   
  If a shareholder exercises an exchange privilege within 90 days of acquiring
the shares, then the loss the shareholder can recognize on the exchange will be
reduced (or the gain increased) to the extent any sales charge paid to the Fund
on the exchanged shares reduces any sales charge such shareholder would have
owed upon purchase of the new shares in the absence of the exchange privilege.
Instead, such sales charge will be treated as an amount paid for the new
shares.     
 
  A loss realized on a sale or exchange of shares of the Fund will be
disallowed if other Fund shares are acquired (whether through the automatic
reinvestment of dividends or otherwise) within a 61-day period beginning 30
days before and ending 30 days after the date that the shares are disposed of.
In such a case, the basis of the shares acquired will be adjusted to reflect
the disallowed loss.
   
  Under certain Code provisions, some shareholders may be subject to a 31%
withholding tax on certain ordinary income dividends and on capital gain
dividends and redemption payments ("backup withholding"). Generally,
shareholders subject to backup withholding will be those for whom no certified
taxpayer identification number is on file with the Trust or who, to the Trust's
knowledge, have furnished an incorrect number. When establishing an account, an
investor must certify under penalty of perjury that such number is correct and
that such investor is not otherwise subject to backup withholding.     
 
 
                                       37

  The Code provides that every person required to file a tax return must
include for information purposes on such return the amount of exempt-interest
dividends received from all sources (including the Fund) during the taxable
year.
   
  The foregoing is a general and abbreviated summary of the applicable
provisions of the Code, Treasury regulations and Pennsylvania income tax laws
presently in effect. For the complete provisions, reference should be made to
the pertinent Code sections, the Treasury regulations promulgated thereunder
and the applicable Pennsylvania income tax laws. The Code and the Treasury
regulations, as well as the Pennsylvania tax laws, are subject to change by
legislative, judicial or administrative action either prospectively or
retroactively.     
 
  Shareholders are urged to consult their tax advisers regarding the
availability of any exemption from state or local taxes and with specific
questions as to Federal, foreign, state or local taxes.
 
                                PERFORMANCE DATA
   
  From time to time the Fund may include its average annual total return, yield
and tax-equivalent yield for various specified time periods in advertisements
or information furnished to present or prospective shareholders. Average annual
total return, yield and tax-equivalent yield are computed separately for
Class A, Class B, Class C and Class D shares in accordance with formulas
specified by the Commission.     
 
  Average annual total return quotations for the specified periods will be
computed by finding the average annual compounded rates of return (based on net
investment income and any realized and unrealized capital gains or losses on
portfolio investments over such periods) that would equate the initial amount
invested to the redeemable value of such investment at the end of each period.
Average annual total return will be computed assuming all dividends and
distributions are reinvested and taking into account all applicable recurring
and nonrecurring expenses, including any CDSC that would be applicable to a
complete redemption of the investment at the end of the specified period such
as in the case of Class B and Class C shares and the maximum sales charge in
the case of Class A and Class D shares. Dividends paid by the Fund with respect
to all shares, to the extent any dividends are paid, will be calculated in the
same manner at the same time on the same day and will be in the same amount,
except that account maintenance fees and distribution charges and any
incremental transfer agency costs relating to each class of shares will be
borne exclusively by that class. The Fund will include performance data for all
classes of shares of the Fund in any advertisement or information including
performance data of the Fund.
 
  The Fund also may quote total return and aggregate total return performance
data for various specified time periods. Such data will be calculated
substantially as described above, except that (1) the rates of return
calculated will not be average annual rates, but rather, actual annual,
annualized or aggregate rates of return and (2) the maximum applicable sales
charges will not be included with respect to annual or annualized rates of
return calculations. Aside from the impact on the performance data calculations
of including or excluding the maximum applicable sales charges, actual annual
or annualized total return data generally will be lower than average annual
total return data since the average annual rates of return reflect compounding;
aggregate total return data generally will be higher than average annual total
return data since the aggregate rates of return reflect compounding over a
longer period of time. In advertisements distributed to investors whose
 
                                       38
<PAGE>
 
purchases are subject to reduced sales loads in the case of Class A shares or
waiver of the CDSC in the case of Class B shares or to reduced sales charges in
the case of Class A or Class D shares, the performance data may take into
account the reduced, and not the maximum, sales charge or may not take into
account the CDSC and therefore may reflect greater total return since, due to
the reduced sales charges or waiver of the contingent deferred sales charge, a
lower amount of expenses is deducted. See "Purchase of Shares." The Fund's
total return may be expressed either as a percentage or as a dollar amount in
order to illustrate such total return on a hypothetical $1,000 investment in
the Fund at the beginning of each specified period.
   
  Yield quotations will be computed based on a 30-day period by dividing (a)
the net income based on the yield of each security earned during the period by
(b) the average daily number of shares outstanding during the period that were
entitled to receive dividends multiplied by the maximum offering price per
share on the last day of the period. Tax-equivalent yield quotations will be
computed by dividing (a) the part of the Fund's yield that is tax-exempt by (b)
one minus a stated tax rate and (c) adding the result to that part, if any, of
the Fund's yield that is not tax-exempt. The yield for the 30-day period ended
July 31, 1995 was 5.01% for Class A shares, 4.71% for Class B shares, 4.60% for
Class C shares and 4.92% for Class D shares and the tax-equivalent yield for
the same period (based on a Federal income tax rate of 28%) was 6.96% for Class
A shares, 6.54% for Class B shares, 6.39% for Class C shares and 6.83% for
Class D shares.     
   
  Total return, yield and tax-equivalent yield figures are based on the Fund's
historical performance and are not intended to indicate future performance. The
Fund's total return, yield and tax-equivalent yield will vary depending on
market conditions, the securities comprising the Fund's portfolio, the Fund's
operating expenses and the amount of realized and unrealized net capital gains
or losses during the period. The value of an investment in the Fund will
fluctuate and an investor's shares, when redeemed, may be worth more or less
than their original cost.     
   
  On occasion, the Fund may compare its performance to performance data
published by Lipper Analytical Services, Inc., Morningstar Publications, Inc.
("Morningstar") and CDA Investment Technology, Inc. or to data contained in
publications such as Money Magazine, U.S. News & World Report, Business Week,
Forbes Magazine and Fortune Magazine. From time to time, the Fund may include
the Fund's Morningstar risk-adjusted performance ratings in advertisements or
supplemental sales literature. As with other performance data, performance
comparisons should not be considered indicative of the Fund's relative
performance for any future period.     
 
                             ADDITIONAL INFORMATION
 
DETERMINATION OF NET ASSET VALUE
   
  The net asset value of the shares of all classes of the Fund is determined
once daily 15 minutes after the close of business on the New York Stock
Exchange (generally, 4:00 P.M., New York time), on each day during which the
New York Stock Exchange is open for trading. The net asset value per share is
computed by dividing the sum of the value of the securities held by the Fund
plus any cash or other assets minus all liabilities by the total number of
shares outstanding at such time, rounded to the nearest cent. Expenses,
including the fees payable to the Manager and the Distributor, are accrued
daily.     
   
  The per share net asset value of Class A shares will generally be higher than
the per share net asset value of shares of the other classes, reflecting the
daily expense accruals of the account maintenance,     
 
                                       39
<PAGE>
 
   
distribution and higher transfer agency fees applicable with respect to the
Class B and Class C shares and the daily expense accruals of the account
maintenance fees applicable with respect to Class D shares; moreover, the per
share net asset value of the Class D shares generally will be higher than the
per share net asset value of the Class B and Class C shares, reflecting the
daily expense accruals of the distribution and higher agency fees applicable
with respect to Class B and Class C shares. It is expected, however, that the
per share net asset value of the classes will tend to converge (although not
necessarily meet) immediately after the payment of dividends or distributions
which will differ by approximately the amount of the expense accrual
differentials between the classes.     
 
ORGANIZATION OF THE TRUST
   
  The Trust is an unincorporated business trust organized on August 2, 1985
under the laws of Massachusetts. On October 1, 1987, the Trust changed its name
from "Merrill Lynch Multi-State-Tax-Exempt Series Trust" to "Merrill Lynch
Multi-State Municipal Bond Series Trust" and on December 22, 1987 the Trust
changed its name to "Merrill Lynch Multi-State Municipal Series Trust". The
Trust is an open-end management investment company comprised of separate series
("Series"), each of which is a separate portfolio offering shares to selected
groups of purchasers. Each of the Series is to be managed independently in
order to provide to shareholders who are residents of the state to which such
Series relates as high a level of income exempt from Federal and, in certain
cases, state and local income taxes as is consistent with prudent investment
management. The Trustees are authorized to create an unlimited number of Series
and, with respect to each Series, to issue an unlimited number of full and
fractional shares of beneficial interest of $.10 par value of different
classes. Shareholder approval is not required for the authorization of
additional Series or classes of a Series of the Trust. At the date of this
Prospectus, the shares of the Fund are divided into Class A, Class B, Class C
and Class D shares. Class A, Class B, Class C and Class D shares represent
interests in the same assets of the Fund and are identical in all respects
except that Class B, Class C and Class D shares bear certain expenses related
to the account maintenance associated with such shares, and Class B and Class C
shares bear certain expenses related to the distribution of such shares. Each
class has exclusive voting rights with respect to matters relating to account
maintenance and distribution expenditures as applicable. See "Purchase of
Shares". The Trust has received an order (the "Order") from the Commission
permitting the issuance and sale of multiple classes of shares. The Trustees of
the Trust may classify and reclassify the shares of any Series into additional
classes at a future date. The Order permits the Trust to issue additional
classes of shares of any Series if the Board of Trustees deems such issuance to
be in the best interest of the Trust.     
 
  Shareholders are entitled to one vote for each full share and to fractional
votes for fractional shares held in the election of Trustees (to the extent
hereinafter provided) and on other matters submitted to the vote of
shareholders. There normally will be no meeting of shareholders for the purpose
of electing Trustees unless and until such time as less than a majority of the
Trustees holding office have been elected by shareholders, at which time the
Trustees then in office will call a shareholders' meeting for the election of
Trustees. Shareholders may, in accordance with the terms of the Declaration of
Trust, cause a meeting of shareholders to be held for the purpose of voting on
the removal of Trustees. Also, the Trust will be required to call a special
meeting of shareholders of a Series in accordance with the requirements of the
1940 Act to seek approval of new management and advisory arrangements, of a
material increase in distribution fees or of a change in the fundamental
policies, objectives or restrictions of a Series. Except as set forth above,
the
 
                                       40
<PAGE>
 
Trustees shall continue to hold office and appoint successor Trustees. Each
issued and outstanding share is entitled to participate equally in dividends
and distributions declared by the respective Series and in net assets of such
Series upon liquidation or dissolution remaining after satisfaction of
outstanding liabilities except that, as noted above, Class B, Class C and Class
D shares bear certain additional expenses. The obligations and liabilities of a
particular Series are restricted to the assets of that Series and do not extend
to the assets of the Trust generally. The shares of each Series, when issued,
will be fully-paid and non-assessable by the Trust.
 
SHAREHOLDER REPORTS
 
  Only one copy of each shareholder report and certain shareholder
communications will be mailed to each identified shareholder regardless of the
number of accounts such shareholder has. If a shareholder wishes to receive
copies of each report and communication for all of the shareholder's related
accounts the shareholder should notify in writing:
      
   Merrill Lynch Financial Data Services, Inc.     
          
   P.O. Box 45289
   Jacksonville, FL 32232-5289
   
The written notification should include the shareholder's name, address, tax
identification number and Merrill Lynch, Pierce, Fenner & Smith Incorporated
and/or mutual fund account numbers. If you have any questions regarding this
please call your Merrill Lynch financial consultant or Merrill Lynch Financial
Data Services, Inc. at 800-637-3863.     
 
SHAREHOLDER INQUIRIES
 
  Shareholder inquiries may be addressed to the Trust at the address or
telephone number set forth on the cover page of this Prospectus.
 
                               ----------------
 
  The Declaration of Trust establishing the Trust, dated August 2, 1985, a copy
of which together with all amendments thereto (the "Declaration"), is on file
in the office of the Secretary of the Commonwealth of Massachusetts, provides
that the name "Merrill Lynch Multi-State Municipal Series Trust" refers to the
Trustees under the Declaration collectively as Trustees, but not as individuals
or personally. No Trustee, shareholder, officer, employee or agent of the Trust
shall be held to any personal liability, nor shall resort be had to their
private property for the satisfaction of any obligation or claim of the Trust
but the "Trust Property" only shall be liable.

  Merrill Lynch Pennsylvania Municipal Bond Fund (the "Fund") is a series of
Merrill Lynch Multi-State Municipal Series Trust (the "Trust"), an open-end
management investment company organized as a Massachusetts business trust. The
investment objective of the Fund is to provide shareholders with as high a
level of income exempt from Federal and Pennsylvania personal income taxes as
is consistent with prudent investment management. The Fund invests primarily in
a portfolio of long-term investment grade obligations issued by or on behalf of
the Commonwealth of Pennsylvania, its political subdivisions, agencies and
instrumentalities and obligations of other qualifying issuers, such as issuers
located in Puerto Rico, the Virgin Islands, and Guam, which pay interest
exempt, in the opinion of bond counsel to the issuer, from Federal and
Pennsylvania personal income taxes. There can be no assurance that the
investment objective of the Fund will be realized.     
 
  Pursuant to the Merrill Lynch Select Pricing (SM) System, the Fund offers four
classes of shares, each with a different combination of sales charges, ongoing
fees and other features. The Merrill Lynch Select PricingSM System permits an
investor to choose the method of purchasing shares that the investor believes
is most beneficial given the amount of the purchase, the length of time the
investor expects to hold the shares and other relevant circumstances.

                       INVESTMENT OBJECTIVE AND POLICIES
 
  The investment objective of the Fund is to provide shareholders with as high
a level of income exempt from Federal and Pennsylvania personal income taxes as
is consistent with prudent investment management. The Fund seeks to achieve its
objective by investing primarily in a portfolio of long-term obligations issued
by or on behalf of the Commonwealth of Pennsylvania, its political
subdivisions, agencies and instrumentalities and obligations of other
qualifying issuers, such as issuers located in Puerto Rico, the Virgin Islands
and Guam, which pay interest exempt, in the opinion of bond counsel to the
issuer, from Federal and Pennsylvania income taxes. Obligations exempt from
Federal income taxes are referred to herein as "Municipal Bonds" and
obligations exempt from both Federal and Pennsylvania income taxes are referred
to as "Pennsylvania Municipal Bonds". Unless otherwise indicated, references to
Municipal Bonds shall be deemed to include Pennsylvania Municipal Bonds. The
Fund anticipates that at all times, except during temporary defensive periods,
it will maintain at least 65% of its total assets invested in Pennsylvania
Municipal Bonds. At times, the Fund will seek to hedge its portfolio through
the use of futures transactions to reduce volatility in the net asset value of
Fund shares. Reference is made to "Investment Objective and Policies" in the
Prospectus for a discussion of the investment objective and policies of the
Fund.
 
  Municipal Bonds may include general obligation bonds of the State and its
political subdivisions, revenue bonds of utility systems, highways, bridges,
port and airport facilities, colleges, hospitals, housing facilities, etc., and
industrial development bonds ("IDBs") or private activity bonds. The interest
on such obligations may bear a fixed rate or be payable at a variable or
floating rate. The Municipal Bonds purchased by the Fund will be what are
commonly referred to as "investment grade" securities, which are obligations
rated at the time of purchase within the four highest quality ratings as
determined by either Moody's Investors Service ("Moody's") (currently Aaa, Aa,
A and Baa), Standard & Poor's Corporation ("Standard & Poor's") (currently AAA,
AA, A and BBB), or Fitch Investors Service, Inc. ("Fitch") (currently AAA, AA,
A and BBB). If unrated, such securities must possess creditworthiness
comparable, in the opinion of the manager of the Fund, Fund Asset Management,
L.P. (the "Manager" or "FAM"), to other obligations in which the Fund may
invest.
 
  The Fund ordinarily does not intend to realize investment income not exempt
from Federal and Pennsylvania income taxes. However, to the extent that
suitable Pennsylvania Municipal Bonds are not available for investment by the
Fund, the Fund may purchase Municipal Bonds issued by other states, their
agencies and instrumentalities, the interest income on which is exempt, in the
opinion of bond counsel, from Federal, but not Pennsylvania, taxation. The Fund
also may invest in securities not issued by or on behalf of a state or
territory or by an agency or instrumentality thereof, if the Fund nevertheless
believes such securities to be exempt from Federal income taxation ("Non-
Municipal Tax-Exempt Securities"). Non-Municipal Tax-Exempt Securities may
include securities issued by other investment companies that invest in
municipal bonds, to the extent permitted by applicable law. Other Non-Municipal
Tax-Exempt Securities could include trust certificates or other derivative
instruments evidencing interests in one or more Municipal Bonds.
 
  Except when acceptable securities are unavailable as determined by the
Manager, the Fund will under normal circumstances invest at least 65% of its
total assets in Pennsylvania Municipal Bonds. For temporary periods or to
provide liquidity, the Fund has the authority to invest as much as 35% of its
assets in tax-exempt or taxable money market obligations with a maturity of one
year or less (such short-term obligations being
 
                                       2
<PAGE>
 
referred to herein as "Temporary Investments"), except that taxable Temporary
Investments, together with such other instruments as are not exempt from
Pennsylvania taxation, shall not exceed 20% of the Fund's total assets. The
Fund at all times will have at least 80% of its net assets invested in
securities exempt from Federal taxation. However, interest received on certain
otherwise tax-exempt securities which are classified as "private activity
bonds" (in general, bonds that benefit non-governmental entities) may be
subject to an alternative minimum tax. The Fund may purchase such private
activity bonds. See "Distributions and Taxes." In addition, the Fund reserves
the right to invest temporarily a greater portion of its assets in Temporary
Investments for defensive purposes, when, in the judgment of the Manager,
market conditions warrant. The investment objective of the Fund and the
policies set forth in this paragraph are fundamental policies of the Fund which
may not be changed without a vote of a majority of the outstanding shares of
the Fund. The Fund's hedging strategies are not fundamental policies and may be
modified by the Trustees of the Trust without the approval of the Fund's
shareholders.
 
  Municipal Bonds may at times be purchased or sold on a delayed delivery basis
or a when-issued basis. These transactions arise when securities are purchased
or sold by the Fund with payment and delivery taking place in the future, often
a month or more after the purchase. The payment obligation and the interest
rate are each fixed at the time the buyer enters into the commitment. The Fund
will make only commitments to purchase such securities with the intention of
actually acquiring the securities, but the Fund may sell these securities prior
to the settlement date if it is deemed advisable. Purchasing Municipal Bonds on
a when-issued basis involves the risk that the yields available in the market
when the delivery takes place may actually be higher than those obtained in the
transaction itself. If yields so increase, the value of the when-issued
obligation generally will decrease. The Fund will maintain a separate account
at its custodian bank consisting of cash, cash equivalents or high grade,
liquid Municipal Bonds or Temporary Investments (valued on a daily basis) equal
at all times to the amount of the when-issued commitment.
   
  The Fund may invest in Municipal Bonds (and Non-Municipal Tax-Exempt
Securities) the return on which is based on a particular index of value or
interest rates. For example, the Fund may invest in Municipal Bonds that pay
interest based on an index of Municipal Bond interest rates or based on the
value of gold or some other commodity. The principal amount payable upon
maturity of certain Municipal Bonds also may be based on the value of an index.
Also, the Fund may invest in so-called "inverse floating obligations" or
"residual interest bonds" on which the interest rates typically decline as
market rates increase and increase as market rates decline. For example, to the
extent the Fund invests in these types of Municipal Bonds, the Fund's return on
such Municipal Bonds will be subject to risk with respect to the value of the
particular index, which may include reduced or eliminated interest payments and
losses of invested principal. Such securities have the effect of providing a
degree of investment leverage, since they may increase or decrease in value in
response to changes, as an illustration, in market interest rates at a rate
which is a multiple (typically two) of the rate at which fixed-rate long-term
tax exempt securities increase or decrease in response to such changes. As a
result, the market values of such securities will generally be more volatile
than the market values of fixed-rate tax exempt securities. To seek to limit
the volatility of these securities, the Fund may purchase inverse floating
obligations with shorter term maturities or which contain limitations on the
extent to which the interest rate may vary. Certain investments in such
obligations may be illiquid. The Fund may not invest in such illiquid
obligations if such investments, together with other illiquid investments,
would exceed 15% of the Fund's total assets. The Manager believes, however,
that indexed and inverse floating obligations represent flexible portfolio
management instruments for the Fund which allow the Fund to seek     
 
                                       3
<PAGE>
 
   
potential investment rewards, hedge other portfolio positions or vary the
degree of investment leverage relatively efficiently under different market
conditions.     
   
  The Fund may purchase a Municipal Bond issuer's right to call all or a
portion of such Municipal Bond for mandatory tender for purchase (a "Call
Right"). A holder of a Call Right may exercise such right to require a
mandatory tender for the purchase of related Municipal Bonds, subject to
certain conditions. A Call Right that is not exercised prior to the maturity of
the related Municipal Bond will expire without value. The economic effect to
holding both the Call Right and the related Municipal Bond is identical to
holding a Municipal Bond as a non-callable security. Certain investments in
such obligations may be illiquid. The Fund may not invest in such illiquid
obligations if such investments, together with other illiquid investments,
would exceed 15% of the Fund's total assets.     
   
  The Fund may invest up to 20% of its total assets in Municipal Bonds which
are rated below Baa by Moody's or below BBB by Standard & Poor's or Fitch or
which, in the Manager's judgment, possess similar credit characteristics ("high
yield securities"). See Appendix II--"Ratings of Municipal Bonds"--for
additional information regarding ratings of debt securities. The Manager
considers the ratings assigned by Standard & Poor's, Moody's or Fitch as one of
several factors in its independent credit analysis of issuers.     
 
  High yield securities are considered by Standard & Poor's, Moody's and Fitch
to have varying degrees of speculative characteristics. Consequently, although
high yield securities can be expected to provide higher yields, such securities
may be subject to greater market price fluctuations and risk of loss of
principal than lower yielding, higher rated debt securities. Investments in
high yield securities will be made only when, in the judgment of the Manager,
such securities provide attractive total return potential relative to the risk
of such securities, as compared to higher quality debt securities. The Fund
will not invest in debt securities in the lowest rating categories (those rated
CC or lower by Standard & Poor's or Fitch or Ca or lower by Moody's) unless the
Manager believes that the financial condition of the issuer or the protection
afforded the particular securities is stronger than would otherwise be
indicated by such low ratings. The Fund does not intend to purchase debt
securities that are in default or which the Manager believes will be in
default.
 
  Issuers of high yield securities may be highly leveraged and may not have
available to them more traditional methods of financing. Therefore, the risks
associated with acquiring the securities of such issuers generally are greater
than is the case with higher rated securities. For example, during an economic
downturn or a sustained period of rising interest rates, issuers of high yield
securities may be more likely to experience financial stress, especially if
such issuers are highly leveraged. During periods of economic recession, such
issuers may not have sufficient revenues to meet their interest payment
obligations. The issuer's ability to service its debt obligations also may be
adversely affected by specific issuer developments, or the issuer's inability
to meet specific projected business forecasts, or the unavailability of
additional financing. The risk of loss due to default by the issuer is
significantly greater for the holders of high yield securities because such
securities may be unsecured and may be subordinated to other creditors of the
issuer.
 
  High yield securities frequently have call or redemption features that would
permit an issuer to repurchase the security from the Fund. If a call were
exercised by the issuer during a period of declining interest rates, the Fund
likely would have to replace such called security with a lower yielding
security, thus decreasing the net investment income to the Fund and dividends
to shareholders.
 
 
                                       4
<PAGE>
 
  The Fund may have difficulty disposing of certain high yield securities
because there may be a thin trading market for such securities. Because not all
dealers maintain markets in all high yield securities, there is no established
secondary market for many of these securities, and the Fund anticipates that
such securities could be sold only to a limited number of dealers or
institutional investors. To the extent that a secondary trading market for high
yield securities does exist, it generally is not as liquid as the secondary
market for higher rated securities. Reduced secondary market liquidity may have
an adverse impact on market price and the Fund's ability to dispose of
particular issues when necessary to meet the Fund's liquidity needs or in
response to a specific economic event such as a deterioration in the
creditworthiness of the issuer. Reduced secondary market liquidity for certain
securities also may make it more difficult for the Fund to obtain accurate
market quotations for purposes of valuing the Fund's portfolio. Market
quotations generally are available on many high yield securities only from a
limited number of dealers and may not necessarily represent firm bids of such
dealers or prices for actual sales.
 
  It is expected that a significant portion of the high yield securities
acquired by the Fund will be purchased upon issuance, which may involve special
risks because the securities so acquired are new issues. In such instances the
Fund may be a substantial purchaser of the issue and therefore have the
opportunity to participate in structuring the terms of the offering. Although
this may enable the Fund to seek to protect itself against certain of such
risks, the considerations discussed herein would nevertheless remain
applicable.
 
  Adverse publicity and investor perceptions, which may not be based on
fundamental analysis, also may decrease the value and liquidity of high yield
securities, particularly in a thinly traded market. Factors adversely affecting
the market value of high yield securities are likely to adversely affect the
Fund's net asset value. In addition, the Fund may incur additional expenses to
the extent that it is required to seek recovery upon a default on a portfolio
holding or participate in the restructuring of the obligation.
 
            DESCRIPTION OF MUNICIPAL BONDS AND TEMPORARY INVESTMENTS
 
  Set forth below is a description of the Municipal Bonds and Temporary
Investments in which the Fund may invest. A more complete discussion concerning
futures and options transactions is set forth under "Investment Objective and
Policies" in the Prospectus. Information with respect to ratings assigned to
tax-exempt obligations which the Fund may purchase is set forth in Appendix II
to this Statement of Additional Information.
 
DESCRIPTION OF MUNICIPAL BONDS
 
  Municipal Bonds include debt obligations issued to obtain funds for various
public purposes, including construction of a wide range of public facilities,
refunding of outstanding obligations and obtaining funds for general operating
expenses and loans to other public institutions and facilities. In addition,
certain types of bonds are issued by or on behalf of public authorities to
finance various privately operated facilities, including certain facilities for
local furnishing of electric energy or gas, sewage facilities, solid waste
disposal facilities and other specialized facilities. Such obligations are
included within the term Municipal Bonds if the interest paid thereon is, in
the opinion of bond counsel, excluded from gross income for Federal income tax
purposes and, in the case of Pennsylvania Municipal Bonds, exempt from
Pennsylvania personal income taxes. Other types of IDBs or private activity
bonds, the proceeds of which are used for the construction, equipment, repair
 
                                       5
<PAGE>
 
or improvement of privately operated industrial or commercial facilities, may
constitute Municipal Bonds, although the current Federal tax laws place
substantial limitations on the size of such issues.
   
  The two principal classifications of Municipal Bonds are "general obligation"
and "revenue" bonds which latter category includes IDBs and, for bonds issued
after August 15, 1986, private activity bonds. General obligation bonds are
secured by the issuer's pledge of faith, credit and taxing power for the
payment of principal and interest. Revenue bonds are payable only from the
revenues derived from a particular facility or class of facilities or, in some
cases, from the proceeds of a special or limited tax or other specific revenue
source such as from the user of the facility being financed. IDBs and private
activity bonds are in most cases revenue bonds and generally do not constitute
the pledge of the credit or taxing power of the issuer of such bonds.
Generally, the payment of the principal of and interest on such bonds depends
solely on the ability of the user of the facility financed by the bonds to meet
its financial obligations and the pledge, if any, of real and personal property
so financed as security for such payment, unless a line of credit, bond
insurance or other security is furnished. The Fund also may invest in "moral
obligation" bonds, which are normally issued by special purpose public
authorities. If an issuer of moral obligation bonds is unable to meet its
obligations, repayment of such bonds becomes a moral commitment, but not a
legal obligation, of the state or municipality in question.     
   
  Also included within the general category of Municipal Bonds are
participation certificates issued by government authorities or entities to
finance the acquisition or construction of equipment, land and/or facilities.
The certificates represent participations in a lease, an installment purchase
contract or a conditional sales contract (hereinafter collectively called
"lease obligations") relating to such equipment, land or facilities. Although
lease obligations do not constitute general obligations of the issuer for which
the issuer's unlimited taxing power is pledged, a lease obligation is
frequently backed by the issuer's covenant to budget for, appropriate and make
the payments due under the lease obligation. However, certain lease obligations
contain "non-appropriation" clauses which provide that the issuer has no
obligation to make lease or installment purchase payments in future years
unless money is appropriated for such purpose on a yearly basis. Although "non-
appropriation" lease obligations are secured by the leased property,
disposition of the property in the event of foreclosure might prove difficult.
These securities represent a type of financing that has not yet developed the
depth of marketability associated with more conventional securities. Certain
investments in lease obligations may be illiquid. The Fund may not invest in
illiquid lease obligations if such investments, together with all other
illiquid investments, would exceed 15% of the Fund's total assets. The Fund
may, however, invest without regard to such limitation in lease obligations
which the Manager, pursuant to guidelines which have been adopted by the Board
of Trustees and subject to the supervision of the Board, determines to be
liquid. The Manager will deem lease obligations to be liquid if they are
publicly offered and have received an investment grade rating of Baa or better
by Moody's, or BBB or better by Standard & Poor's or Fitch. Unrated lease
obligations, or those rated below investment grade, will be considered liquid
if the obligations come to the market through an underwritten public offering
and at least two dealers are willing to give competitive bids. In reference to
the latter, the Manager must, among other things, also review the
creditworthiness of the municipality obligated to make payment under the lease
obligation and make certain specified determinations based on such factors as
the existence of a rating or credit enhancement such as insurance, the
frequency of trades or quotes for the obligation and the willingness of dealers
to make a market in the obligation.     
 
  Yields on Municipal Bonds are dependent on a variety of factors, including
the general condition of the money market and of the municipal bond market, the
size of a particular offering, the financial condition of
 
                                       6
<PAGE>
 
the issuer, the general conditions of the Municipal Bond market, the maturity
of the obligation, and the rating of the issue. The ability of the Fund to
achieve its investment objective is also dependent on the continuing ability of
the issuers of the bonds in which the Fund invests to meet their obligations
for the payment of interest and principal when due. There are variations in the
risks involved in holding Municipal Bonds, both within a particular
classification and between classifications, depending on numerous factors.
Furthermore, the rights of owners of Municipal Bonds and the obligations of the
issuer of such Municipal Bonds may be subject to applicable bankruptcy,
insolvency and similar laws and court decisions affecting the rights of
creditors generally.
 
DESCRIPTION OF TEMPORARY INVESTMENTS
 
  The Fund may invest in short-term tax-free and taxable securities subject to
the limitations set forth under "Investment Objective and Policies." The tax-
exempt money market securities may include municipal notes, municipal
commercial paper, municipal bonds with a remaining maturity of less than one
year, variable rate demand notes and participations therein. Municipal notes
include tax anticipation notes, bond anticipation notes and grant anticipation
notes. Anticipation notes are sold as interim financing in anticipation of tax
collection, bond sales, government grants or revenue receipts. Municipal
commercial paper refers to short-term unsecured promissory notes generally
issued to finance short-term credit needs. The taxable money market securities
in which the Fund may invest as Temporary Investments consist of U.S.
Government securities, U.S. Government agency securities, domestic bank or
savings institution certificates of deposit and bankers' acceptances, short-
term corporate debt securities such as commercial paper, and repurchase
agreements. These Temporary Investments must have a stated maturity not in
excess of one year from the date of purchase.
 
  Variable rate demand obligations ("VRDOs") are tax-exempt obligations which
contain a floating or variable interest rate adjustment formula and an
unconditional right of demand on the part of the holder thereof to receive
payment of the unpaid principal balance plus accrued interest upon a short
notice period not to exceed seven days. There is, however, the possibility that
because of default or insolvency the demand feature of VRDOs and Participating
VRDOs, described below, may not be honored. The interest rates are adjustable
at intervals (ranging from daily to up to one year) to some prevailing market
rate for similar investments, such adjustment formula being calculated to
maintain the market value of the VRDO at approximately the par value of the
VRDOs on the adjustment date. The adjustments typically are based upon the
prime rate of a bank or some other appropriate interest rate adjustment index.
The Fund may invest in all types of tax-exempt instruments currently
outstanding or to be issued in the future which satisfy the short-term maturity
and quality standards of the Fund.
 
  The Fund also may invest in VRDOs in the form of participation interests
("Participating VRDOs") in variable rate tax-exempt obligations held by a
financial institution, typically a commercial bank. Participating VRDOs provide
the Fund with a specified undivided interest (up to 100%) of the underlying
obligation and the right to demand payment of the unpaid principal balance plus
accrued interest on the Participating VRDOs from the financial institution upon
a specified number of days' notice, not to exceed seven days. In addition, a
Participating VRDO is backed by an irrevocable letter of credit of guaranty of
the financial institution. The Fund would have an undivided interest in the
underlying obligation and thus participate on the same basis as the financial
institution in such obligation except that the financial institution typically
retains fees out of the interest paid on the obligation for servicing the
obligation, providing the letter of credit and issuing the repurchase
commitment. The Fund has been advised by its counsel that the Fund should be
entitled to treat the income received on Participating VRDOs as interest from
tax-exempt obligations.
 
 
                                       7
<PAGE>
 
  VRDOs that contain an unconditional right of demand to receive payment of
the unpaid principal balance plus accrued interest on a notice period
exceeding seven days may be deemed to be illiquid securities. A VRDO with a
demand notice exceeding seven days will therefore be subject to the Fund's
restriction on illiquid investments unless, in the judgment of the Trustees,
such VRDO is liquid. The Trustees may adopt guidelines and delegate to the
Manager the daily function of determining and monitoring liquidity of such
VRDOs. The Trustees, however, will retain sufficient oversight and be
ultimately responsible for such determination.
   
  The Trust has established the following standards with respect to money
market securities in which the Fund invests. Commercial paper investments at
the time of purchase must be rated "A-1+" through "A-3" by Standard & Poor's,
"Prime-1" through "Prime-3" by Moody's, or "F-1+" through "F-3" by Fitch or,
if not rated, the commercial paper must be issued by companies having an
outstanding debt issue rated at least "A" by Standard & Poor's, Fitch or
Moody's. Investments in corporate bonds and debentures (which must have
maturities at the date of purchase of one year or less) must be rated at the
time of purchase at least "A" by Standard & Poor's, Moody's or Fitch. Notes
and VRDOs at the time of purchase must be rated SP-1+/A-1+ through SP-2/A-3 by
Standard & Poor's, MIG-1/VMIG-1 through MIG-4/VMIG-4 by Moody's or F-1 through
F-3 by Fitch. Temporary Investments, if not rated, must be of comparable
quality to securities rated in the above rating categories, in the opinion of
the Manager. The Fund may not invest in any security issued by a commercial
bank or a savings institution unless the bank or institution is organized and
operating in the United States, has total assets of at least one billion
dollars and is a member of the Federal Deposit Insurance Corporation ("FDIC"),
except that up to 10% of total assets may be invested in certificates of
deposit of small institutions if such certificates are fully insured by the
FDIC.     
 
REPURCHASE AGREEMENTS
   
  The Fund may invest in securities pursuant to repurchase agreements.
Repurchase agreements may be entered into only with a member bank of the
Federal Reserve System or a primary dealer in U.S. Government securities or an
affiliate thereof. Under such agreements, the seller agrees, upon entering
into the contract, to repurchase the security from the Fund at a mutually
agreed upon time and price, thereby determining the yield during the term of
the agreement. This results in a fixed rate of return insulated from market
fluctuations during such period. In repurchase agreements, the prices at which
the trades are conducted do not reflect accrued interest on the underlying
obligations. Such agreements usually cover short periods, such as under one
week. Repurchase agreements may be construed to be collateralized loans by the
purchaser to the seller secured by the securities transferred to the
purchaser. In the case of a repurchase agreement, the Fund will require the
seller to provide additional collateral if the market value of the securities
falls below the repurchase price at any time during the term of the repurchase
agreement. In the event of default by the seller under a repurchase agreement
construed to be a collateralized loan, the underlying securities are not owned
by the Fund but only constitute collateral for the seller's obligation to pay
the repurchase price. Therefore, the Fund may suffer time delays and incur
costs or possible losses in connection with the disposition of the collateral.
In the event of a default under such a repurchase agreement, instead of the
contractual fixed rate of return, the rate of return to the Fund will depend
on intervening fluctuations of the market value of such security and the
accrued interest on the security. In such event, the Fund would have rights
against the seller for breach of contract with respect to any losses arising
from market fluctuations following the failure of the seller to perform. The
Fund may not invest in repurchase agreements maturing in     
 
                                       8
<PAGE>
 
   
more than seven days if such investments, together with other illiquid
securities, would exceed 15% (10% to the extent required by certain state laws)
of the Fund's total assets.     
 
  In general, for Federal and Pennsylvania income tax purposes, repurchase
agreements are treated as collateralized loans secured by the securities
"sold." Therefore, amounts earned under such agreements will not be considered
tax-exempt interest.
 
FINANCIAL FUTURES TRANSACTIONS AND OPTIONS
 
  Reference is made to the discussion concerning futures transactions under
"Investment Objective and Policies" in the Prospectus. Set forth below is
additional information concerning these transactions.
   
  As described in the Prospectus, the Fund may purchase and sell exchange
traded financial futures contracts ("financial futures contracts") to hedge its
portfolio of Municipal Bonds against declines in the value of such securities
and to hedge against increases in the cost of securities the Fund intends to
purchase. However, any transactions involving financial futures or options (and
puts and calls associated therewith) will be in accordance with the Fund's
investment policies and limitations. To hedge its portfolio, the Fund may take
an investment position in a futures contract which will move in the opposite
direction from the portfolio position being hedged. While the Fund's use of
hedging strategies is intended to moderate capital changes in portfolio
holdings and thereby reduce the volatility of the net asset value of Fund
shares, the Fund anticipates that its net asset value will fluctuate. Set forth
below is information concerning futures transactions.     
 
  Description of Futures Contracts. A futures contract is an agreement between
two parties to buy and sell a security, or in the case of an index-based
futures contract, to make and accept a cash settlement for a set price on a
future date. A majority of transactions in futures contracts, however, do not
result in the actual delivery of the underlying instrument or cash settlement,
but are settled through liquidation, i.e., by entering into an offsetting
transaction. Futures contracts have been designed by boards of trade which have
been designated "contracts markets" by the Commodity Futures Trading Commission
("CFTC").
 
  The purchase or sale of a futures contract differs from the purchase or sale
of a security in that no price or premium is paid or received. Instead, an
amount of cash or securities acceptable to the broker and the relevant contract
market, which varies, but is generally about 5% of the contract amount must be
deposited with the broker. This amount is known as "initial margin" and
represents a "good faith" deposit assuring the performance of both the
purchaser and seller under the futures contract. Subsequent payments to and
from the broker, called "variation margin", are required to be made on a daily
basis as the price of the futures contract fluctuates making the long and short
positions in the futures contract more or less valuable, a process known as
"mark to the market." At any time prior to the settlement date of the futures
contract, the position may be closed out by taking an opposite position which
will operate to terminate the position in the futures contract. A final
determination of variation margin is then made, additional cash is required to
be paid to or released by the broker and the purchase realizes a loss or gain.
In addition, a nominal commission is paid on each completed sale transaction.
 
  The Fund deals in financial futures contracts based on a long-term municipal
bond index developed by the Chicago Board of Trade ("CBT") and The Bond Buyer
(the "Municipal Bond Index"). The Municipal
 
                                       9
<PAGE>
 
Bond Index is comprised of 40 tax-exempt municipal revenue and general
obligations bonds. Each bond included in the Municipal Bond Index must be rated
A or higher by Moody's or Standard & Poor's and must have a remaining maturity
of 19 years or more. Twice a month new issues satisfying the eligibility
requirements are added to, and an equal number of old issues are deleted from,
the Municipal Bond Index. The value of the Municipal Bond Index is computed
daily according to a formula based on the price of each bond in the Municipal
Bond Index, as evaluated by six dealer-to-dealer brokers.
 
  The Municipal Bond Index futures contract is traded only on the CBT. Like
other contract markets, the CBT assures performance under futures contracts
through a clearing corporation, a non-profit organization managed by the
exchange membership which also is responsible for handling daily accounting of
deposits or withdrawals of margin.
 
  As described in the Prospectus, the Fund may purchase and sell financial
futures contracts on U.S. Government securities as a hedge against adverse
changes in interest rates as described below. With respect to U.S. Government
securities, currently there are financial futures contracts based on long-term
U.S. Treasury bonds, Treasury notes, Government National Mortgage Association
Certificates and three-month U.S. Treasury bills. The Fund may purchase and
write call and put options on futures contracts on U.S. Government securities
in connection with its hedging strategies.
 
  Subject to policies adopted by the Trustees, the Fund also may engage in
other futures contracts transactions such as futures contracts on other
municipal bond indices which may become available if the Manager and the
Trustees should determine that there is normally a sufficient correlation
between the prices of such futures contracts and the Municipal Bonds in which
the Fund invests to make such hedging appropriate.
 
  Futures Strategies. The Fund may sell a financial futures contract (i.e.,
assume a short position) in anticipation of a decline in the value of its
investments in Municipal Bonds resulting from an increase in interest rates or
otherwise. The risk of decline could be reduced without employing futures as a
hedge by selling such Municipal Bonds and either reinvesting the proceeds in
securities with shorter maturities or by holding assets in cash. This strategy,
however, entails increased transaction costs in the form of dealer spreads and
typically would reduce the average yield of the Fund's portfolio securities as
a result of the shortening of maturities. The sale of futures contracts
provides an alternative means of hedging against declines in the value of its
investments in Municipal Bonds. As such values decline, the value of the Fund's
positions in the futures contracts will tend to increase, thus offsetting all
or a portion of the depreciation in the market value of the Fund's Municipal
Bond investments which are being hedged. While the Fund will incur commission
expenses in selling and closing out futures positions, commissions on futures
transactions are lower than transaction costs incurred in the purchase and sale
of Municipal Bonds. In addition, the ability of the Fund to trade in the
standardized contracts available in the futures markets may offer a more
effective defensive position than a program to reduce the average maturity of
the portfolio securities due to the unique and varied credit and technical
characteristics of the municipal debt instruments available to the Fund.
Employing futures as a hedge also may permit the Fund to assume a defensive
posture without reducing the yield on its investments beyond any amounts
required to engage in futures trading.
   
  When the Fund intends to purchase Municipal Bonds, the Fund may purchase
futures contracts as a hedge against any increase in the cost of such Municipal
Bonds resulting from a decrease in interest rates     
 
                                       10
<PAGE>
 
or otherwise, that may occur before such purchases can be effected. Subject to
the degree of correlation between the Municipal Bonds and the futures
contracts, subsequent increases in the cost of Municipal Bonds should be
reflected in the value of the futures held by the Fund. As such purchases are
made, an equivalent amount of futures contracts will be closed out. Due to
changing market conditions and interest rate forecasts, however, a futures
position may be terminated without a corresponding purchase of portfolio
securities.
 
  Call Options on Futures Contracts. The Fund also may purchase and sell
exchange traded call and put options on financial futures contracts on U.S.
Government securities. However, any transactions involving call and put options
on futures contracts will be in accordance with the Fund's investment policies
and limitations. See "Investment Objective and Policies--Investment
Restrictions" in the Prospectus. The purchase of a call option on a futures
contract is analogous to the purchase of a call option on an individual
security. Depending on the pricing of the option compared to either the futures
contract on which it is based, or on the price of the underlying debt
securities, it may or may not be less risky than ownership of the futures
contract or underlying debt securities. Like the purchase of a futures
contract, the Fund will purchase a call option on a futures contract to hedge
against a market advance when the Fund is not fully invested.
 
  The writing of a call option on a futures contract constitutes a partial
hedge against declining prices of the securities which are deliverable upon
exercise of the futures contract. If the futures price at expiration is below
the exercise price, the Fund will retain the full amount of the option premium
which provides a partial hedge against any decline that may have occurred in
the Fund's portfolio holdings.
 
  Put Options on Futures Contracts. The purchase of options on a futures
contract is analogous to the purchase of protective put options on portfolio
securities. The Fund will purchase put options on futures contracts to hedge
the Fund's portfolio against the risk of rising interest rates.
 
  The writing of a put option on a futures contract constitutes a partial hedge
against increasing prices of the securities which are deliverable upon exercise
of the futures contract. If the futures price at expiration is higher than the
exercise price, the Fund will retain the full amount of the option premium
which provides a partial hedge against any increase in the price of Municipal
Bonds which the Fund intends to purchase.
 
  The writer of an option on a futures contract is required to deposit initial
and variation margin pursuant to requirements similar to those applicable to
futures contracts. Premiums received from the writing of an option will be
included in initial margin. The writing of an option on a futures contract
involves risks similar to those relating to futures contracts.
 
                               ----------------
 
  The Trust has received an order from the Commission exempting it from the
provisions of Section 17(f) and Section 18(f) of the Investment Company Act of
1940, as amended (the "1940 Act") in connection with its strategy of investing
in futures contracts. Section 17(f) relates to the custody of securities and
other assets of an investment company and may be deemed to prohibit certain
arrangements between the Trust and commodities brokers with respect to initial
and variation margin. Section 18(f) of the 1940 Act prohibits an open-end
investment company such as the Trust from issuing a "senior security" other
than a borrowing from a bank. The staff of the Commission has in the past
indicated that a futures contract may be a "senior security" under the 1940
Act.
 
 
                                       11
<PAGE>
 
  Restrictions on Use of Futures Transactions. Regulations of the CFTC
applicable to the Fund require that all of the Fund's futures transactions
constitute bona fide hedging transactions and that the Fund purchase and sell
futures contracts and options thereon (i) for bona fide hedging purposes, and
(ii) for non-hedging purposes, if the aggregate initial margin and premiums
required to establish positions in such contracts and options does not exceed
5% of the liquidation value of the Fund's portfolio assets after taking into
account unrealized profits and unrealized losses on any such contracts and
options. (However, the Fund intends to engage in options and futures
transactions only for hedging purposes.) Margin deposits may consist of cash or
securities acceptable to the broker and the relevant contract market.
 
  When the Fund purchases futures contracts or a call option with respect
thereto or writes a put option on a futures contract, an amount of cash, cash
equivalents or short-term, high-grade, fixed income securities will be
deposited in a segregated account with the Fund's custodian so that the amount
so segregated, plus the amount of initial and variation margin held in the
account of its broker, equals the market value of the futures contract, thereby
ensuring that the use of such futures is unleveraged.
 
  Risk Factors in Futures Transactions and Options. Investment in futures
contracts involves the risk of imperfect correlation between movements in the
price of the futures contract and the price of the security being hedged. The
hedge will not be fully effective when there is imperfect correlation between
the movements in the prices of two financial instruments. For example, if the
price of the futures contract moves more than the price of the hedged security,
the Fund will experience either a loss or gain on the futures contract which is
not completely offset by movements in the price of the hedged securities. To
compensate for imperfect correlations, the Fund may purchase or sell futures
contracts in a greater dollar amount than the hedged securities if the
volatility of the hedged securities is historically greater than the volatility
of the futures contracts. Conversely, the Fund may purchase or sell fewer
futures contracts if the volatility of the price of the hedged securities is
historically less than that of the futures contracts.
 
  The particular municipal bonds comprising the index underlying the Municipal
Bond Index financial futures contract may vary from the Municipal Bonds held by
the Fund. As a result, the Fund's ability to hedge effectively all or a portion
of the value of its Municipal Bonds through the use of such financial futures
contracts will depend in part on the degree to which price movements in the
index underlying the financial futures contract correlate with the price
movements of the Municipal Bonds held by the Fund. The correlation may be
affected by disparities in the average maturity, ratings, geographical mix or
structure of the Fund's investments as compared to those comprising the
Municipal Bond Index, and general economic or political factors. In addition,
the correlation between movements in the value of the Municipal Bond Index may
be subject to change over time as additions to and deletions from the Municipal
Bond Index alter its structure. The correlation between futures contracts on
U.S. Government securities and the Municipal Bonds held by the Fund may be
adversely affected by similar factors and the risk of imperfect correlation
between movements in the prices of such futures contracts and the prices of the
Municipal Bonds held by the Fund may be greater.
 
  The Fund expects to liquidate a majority of the futures contracts it enters
into through offsetting transactions on the applicable contract market. There
can be no assurance, however, that a liquid secondary market will exist for any
particular futures contract at any specific time. Thus, it may not be possible
to close out a futures position. In the event of adverse price movements, the
Fund would continue to be required to
 
                                       12
<PAGE>
 
make daily cash payments of variation margin. In such situations, if the Fund
has insufficient cash, it may be required to sell portfolio securities to meet
daily variation margin requirements at a time when it may be disadvantageous to
do so. The inability to close out futures positions also could have an adverse
impact on the Fund's ability to hedge effectively its investments in Municipal
Bonds. The Fund will enter into a futures position only if, in the judgment of
the Manager, there appears to be an actively traded secondary market for such
futures contracts.
 
  The successful use of transactions in futures and related options also
depends on the ability of the Manager to forecast correctly the direction and
extent of interest rate movements within a given time frame. To the extent
interest rates remain stable during the period in which a futures contract or
option is held by the Fund or such rates move in a direction opposite to that
anticipated, the Fund may realize a loss on the hedging transaction which is
not fully or partially offset by an increase in the value of portfolio
securities. As a result, the Fund's total return for such period may be less
than if it had not engaged in the hedging transaction.
 
  Because of low initial margin deposits made on the opening of a futures
position, futures transactions involve substantial leverage. As a result,
relatively small movements in the price of the futures contracts can result in
substantial unrealized gains or losses. Because the Fund will engage in the
purchase and sale of futures contracts solely for hedging purposes, however,
any losses incurred in connection therewith should, if the hedging strategy is
successful, be offset in whole or in part by increases in the value of
securities held by the Fund or decreases in the price of securities the Fund
intends to acquire.
 
  The amount of risk the Fund assumes when it purchases an option on a futures
contract is the premium paid for the option plus related transaction costs. In
addition to the correlation risks discussed above, the purchase of an option on
a futures contract also entails the risk that changes in the value of the
underlying futures contract will not be reflected fully in the value of the
option purchased.
   
  Municipal Bond Index futures contracts were approved for trading in 1986.
Trading in such futures contracts may tend to be less liquid than that in other
futures contracts. The trading of futures contracts also is subject to certain
market risks, such as inadequate trading activity, which could at times make it
difficult or impossible to liquidate existing positions.     
 
                            INVESTMENT RESTRICTIONS
   
  The Fund has adopted a number of fundamental and non-fundamental restrictions
and policies relating to the investment of its assets and its activities. The
fundamental policies set forth below may not be changed without the approval of
the holders of a majority of the Fund's outstanding voting securities (which
for this purpose and under the 1940 Act means the lesser of (i) 67% of the
Fund's shares present at a meeting, at which more than 50% of the outstanding
shares of the Fund are represented or (ii) more than 50% of the Fund's
outstanding shares). The Fund may not:     
       
          
    1. Invest more than 25% of its assets, taken at market value at the time
  of each investment, in the securities of issuers in any particular industry
  (excluding the U.S. Government and its agencies and instrumentalities). For
  purposes of this restriction, states, municipalities and their political
  subdivisions are not considered part of any industry.     
 
                                       13
<PAGE>
 
    2. Make investments for the purpose of exercising control or management.
 
    3. Purchase or sell real estate, except that, to the extent permitted by
  applicable law, the Fund may invest in securities directly or indirectly
  secured by real estate or interests therein or issued by companies which
  invest in real estate or interests therein.
 
    4. Make loans to other persons, except that the acquisition of bonds,
  debentures or other corporate debt securities and investment in government
  obligations, commercial paper, pass-through instruments, certificates of
  deposit, bankers' acceptances, repurchase agreements or any similar
  instruments shall not be deemed to be the making of a loan, and except
  further that the Fund may lend its portfolio securities, provided that the
  lending of portfolio securities may be made only in accordance with
  applicable law and the guidelines set forth in the Fund's Prospectus and
  Statement of Additional Information, as they may be amended from time to
  time.
 
    5. Issue senior securities to the extent such issuance would violate
  applicable law.
 
    6. Borrow money, except that (i) the Fund may borrow from banks (as
  defined in the 1940 Act) in amounts up to 33 1/3% of its total assets
  (including the amount borrowed), (ii) the Fund may borrow up to an
  additional 5% of its total assets for temporary purposes, (iii) the Fund
  may obtain such short-term credit as may be necessary for the clearance of
  purchases and sales of portfolio securities and (iv) the Fund may purchase
  securities on margin to the extent permitted by applicable law. The Fund
  may not pledge its assets other than to secure such borrowings or, to the
  extent permitted by the Fund's investment policies as set forth in its
  Prospectus and Statement of Additional Information, as they may be amended
  from time to time, in connection with hedging transactions, short sales,
  when-issued and forward commitment transactions and similar investment
  strategies.
     
    7. Underwrite securities of other issuers, except insofar as the Fund
  technically may be deemed an underwriter under the Securities Act of 1933,
  as amended (the "Securities Act"), in selling portfolio securities.     
 
    8. Purchase or sell commodities or contracts on commodities, except to
  the extent that the Fund may do so in accordance with applicable law and
  the Fund's Prospectus and Statement of Additional Information, as they may
  be amended from time to time, and without registering as a commodity pool
  operator under the Commodity Exchange Act.
   
  Under the non-fundamental investment restrictions, the Fund may not:     
 
    a. Purchase securities of other investment companies, except to the
  extent such purchases are permitted by applicable law.
 
    b. Make short sales of securities or maintain a short position, except to
  the extent permitted by applicable law. The Fund currently does not intend
  to engage in short sales, except short sales "against the box".
     
    c. Invest in securities which cannot be readily resold because of legal
  or contractual restrictions or which cannot otherwise be marketed, redeemed
  or put to the issuer or a third party, if at the time of acquisition more
  than 15% of its total assets would be invested in such securities. This
  restriction shall not apply to securities which mature within seven days or
  securities which the Board of Trustees of the Fund has otherwise determined
  to be liquid pursuant to applicable law.     
 
                                       14
<PAGE>
 
    d. Invest in warrants if, at the time of acquisition, its investments in
  warrants, valued at the lower of cost or market value, would exceed 5% of
  the Fund's net assets; included within such limitation, but not to exceed
  2% of the Fund's net assets, are warrants which are not listed on the New
  York Stock Exchange or American Stock Exchange or a major foreign exchange.
  For purposes of this restriction, warrants acquired by the Fund in units or
  attached to securities may be deemed to be without value.
 
    e. Invest in securities of companies having a record, together with
  predecessors, of less than three years of continuous operation, if more
  than 5% of the Fund's total assets would be invested in such securities.
  This restriction shall not apply to mortgage-backed securities, asset-
  backed securities or obligations issued or guaranteed by the U.S.
  Government, its agencies or instrumentalities.
     
    f. Purchase or retain the securities of any issuer, if those individual
  officers and Trustees of the Fund, the officers and general partner of the
  Manager, the directors of such general partner or the officers and
  directors of any subsidiary thereof each owning beneficially more than one-
  half of one percent of the securities of such issuer own in the aggregate
  more than 5% of the securities of such issuer.     
 
    g. Invest in real estate limited partnership interests or interests in
  oil, gas or other mineral leases, or exploration or development programs,
  except that the Fund may invest in securities issued by companies that
  engage in oil, gas or other mineral exploration or development activities.
 
    h. Write, purchase or sell puts, calls, straddles, spreads or
  combinations thereof, except to the extent permitted in the Fund's
  Prospectus and Statement of Additional Information, as they may be amended
  from time to time.
     
    i. Notwithstanding fundamental investment restriction (6) above, borrow
  amounts in excess of 20% of its total assets taken at market value
  (including the amount borrowed), and then only from banks as a temporary
  measure for extraordinary or emergency purposes. In addition, the Fund will
  not purchase securities while borrowings are outstanding.     
   
  In addition, to comply with Federal income tax requirements for qualification
as a "regulated investment company", the Fund's investments will be limited in
a manner such that, at the close of each quarter of each fiscal year, (a) no
more than 25% of the Fund's total assets are invested in the securities of a
single issuer, and (b) with regard to at least 50% of the Fund's total assets,
no more than 5% of its total assets are invested in the securities of a single
issuer. For purposes of this restriction, the Fund will regard each state and
each political subdivision, agency or instrumentality of such state and each
multi-state agency of which such state is a member and each public authority
which issues securities on behalf of a private entity as a separate issuer,
except that if the security is backed only by the assets and revenues of a non-
government entity then the entity with the ultimate responsibility for the
payment of interest and principal may be regarded as the sole issuer. These
tax-related limitations may be changed by the Trustees of the Trust to the
extent necessary to comply with changes to the Federal tax requirements.     
   
  Because of the affiliation of Merrill Lynch, Pierce, Fenner & Smith
Incorporated ("Merrill Lynch") with the Trust, the Trust is prohibited from
engaging in certain transactions involving such firm or its affiliates except
pursuant to a permissive order or otherwise in compliance with the provisions
of the 1940 Act and the rules and regulations thereunder. Included among such
restricted transactions are purchases from or sales to     
 
                                       15

COMPENSATION OF TRUSTEES     
   
  The Trust pays each Trustee not affiliated with the Manager a fee of $10,000
per year plus $1,000 per meeting attended, together with such Trustee's actual
out-of-pocket expenses relating to attendance at meetings. The Trust also
compensates members of its Audit and Nominating Committee, which consists of
all the non-affiliated Trustees, a fee of $2,000 per year plus $500 per
meeting attended. The Trust reimburses each unaffiliated Trustee for his out-
of-pocket expenses relating to attendance at Board and Committee meetings. The
fees and expenses of the Trustees are allocated to the respective series of
the Trust on the basis of asset size. For the fiscal year ended July 31, 1995,
fees and expenses paid to unaffiliated Trustees aggregated $7,393.

MANAGEMENT AND ADVISORY ARRANGEMENTS
 
  Reference is made to "Management of the Trust--Management and Advisory
Arrangements" in the Prospectus for certain information concerning the
management and advisory arrangements of the Fund.
 
  Securities may be held by, or be appropriate investments for, the Fund as
well as other funds or investment advisory clients of the Manager or its
affiliates. Because of different objectives or other factors, a particular
security may be bought for one or more clients when one or more clients are
selling the same security. If the Manager or its affiliates purchase or sell
securities for the Fund or other funds for which they act as manager or for
their advisory clients arise for consideration at or about the same time,
transactions in such securities will be made, insofar as feasible, for the
respective funds and clients in a manner deemed equitable to all. To the extent
that transactions on behalf of more than one client of the Manager or its
affiliates during the same period may increase the demand for securities being
purchased or the supply of securities being sold, there may be an adverse
effect on price.
   
  Pursuant to a management agreement between the Trust on behalf of the Fund
and the Manager (the "Management Agreement"), the Manager receives for its
services to the Fund monthly compensation based upon the average daily net
assets of the Fund at the following annual rates: 0.55% of the average daily
net assets not exceeding $500 million; 0.525% of the average daily net assets
exceeding $500 million but not exceeding $1.0 billion and 0.50% of the average
daily net assets exceeding $1.0 billion. For the fiscal years ended July 31,
1994 and 1995, the total advisory fees paid by the Fund to the Manager were
$852,481 and $827,537, respectively.     
 
                                       18
<PAGE>
 
   
  California imposes limitations on the expenses of the Fund. These annual
expense limitations require that the Manager reimburse the Fund in an amount
necessary to prevent the aggregate ordinary operating expenses (excluding
taxes, brokerage fees and commissions, distribution fees and extraordinary
charges such as litigation costs) from exceeding in any fiscal year 2.5% of the
Fund's first $30,000,000 of average net assets, 2.0% of the next $70,000,000 of
average net assets and 1.5% of the remaining average net assets. The Manager's
obligation to reimburse the Fund is limited to the amount of the management
fee. Expenses not covered by the limitation are interest, taxes, brokerage
commissions and other items such as extraordinary legal expenses. No fee
payment will be made to the Manager during any fiscal year which will cause
such expenses to exceed expense limitations at the time of such payment. No fee
reimbursements were made during the years ended July 31, 1993, 1994 and 1995
pursuant to these operating expense limitations.     
   
  The Management Agreement obligates the Manager to provide investment advisory
services and to pay all compensation of and furnish office space for officers
and employees of the Trust connected with investment and economic research,
trading and investment management of the Trust, as well as the compensation of
all Trustees of the Trust who are affiliated persons of ML & Co. or any of its
affiliates. The Fund pays all other expenses incurred in its operation and, if
other Series shall be added ("Series"), a portion of the Trust's general
administrative expenses will be allocated on the basis of the asset size of the
respective Series. Expenses that will be borne directly by the Series include,
among other things, redemption expenses, expenses of portfolio transactions,
expenses of registering the shares under Federal and state securities laws,
pricing costs (including the daily calculation of net asset value), expenses of
printing shareholder reports, prospectuses and statements of additional
information (except to the extent paid by the Distributor as described below),
fees for legal and auditing services, Commission fees, interest, certain taxes,
and other expenses attributable to a particular Series. Expenses which will be
allocated on the basis of asset size of the respective Series include fees and
expenses of unaffiliated Trustees, state franchise taxes, costs of printing
proxies and other expenses related to shareholder meetings, and other expenses
properly payable by the Trust. The organizational expenses of the Trust were
paid by the Trust, and if additional Series are added to the Trust, the
organizational expenses are allocated among the Series (including the Fund) in
a manner deemed equitable by the Trustees. Depending upon the nature of a
lawsuit, litigation costs may be assessed to the specific Series to which the
lawsuit relates or allocated on the basis of the asset size of the respective
Series. The Trustees have determined that this is an appropriate method of
allocation of expenses. Accounting services are provided to the Fund by the
Manager and the Fund reimburses the Manager for its costs in connection with
such services. For the year ended July 31, 1995, the Fund reimbursed the
Manager $40,065 for accounting services. As required by the Fund's distribution
agreements, the Distributor will pay the promotional expenses of the Fund
incurred in connection with the offering of shares of the Fund. Certain
expenses in connection with the account maintenance and distribution of Class B
shares will be financed by the Fund pursuant to the Distribution Plan in
compliance with Rule 12b-1 under the 1940 Act. See "Purchase of Shares--
Distribution Plan".     
   
  The Manager is a limited partnership, the partners of which are ML & Co. and
Princeton Services. ML & Co. and Princeton Services are "controlling persons"
of the Manager as defined under the 1940 Act because of their ownership of its
voting securities or their power to exercise a controlling influence over its
management or policies.     
 
                                       19

  Duration and Termination. Unless earlier terminated as described herein, the
Management Agreement will remain in effect from year to year if approved
annually (a) by the Trustees of the Trust or by a majority of the outstanding
shares of the Fund and (b) by a majority of the Trustees who are not parties to
such contract or interested persons (as defined in the 1940 Act) of any such
party. Such contracts are not assignable and may be terminated without penalty
on 60 days' written notice at the option of either party thereto or by vote of
the shareholders of the Fund.
 
                               PURCHASE OF SHARES
 
  Reference is made to "Purchase of Shares" in the Prospectus for certain
information as to the purchase of Fund shares.
   
  The Fund issues four classes of shares under the Merrill Lynch Select Pricing
(SM) System: shares of Class A and Class D are sold to investors choosing the
initial sales charge alternatives, and shares of Class B and Class C are sold to
investors choosing the deferred sales charge alternatives. Each Class A, Class
B, Class C and Class D share of the Fund represents identical interests in the
investment portfolio of the Fund and has the same rights, except that Class B,
Class C and Class D shares bear the expenses of the ongoing account maintenance
fees, and Class B and Class C shares bear the expenses of the ongoing
distribution fees and the additional incremental transfer agency costs resulting
from the deferred sales charge arrangements. Class B, Class C and Class D shares
each have exclusive voting rights with respect to the Rule 12b-1 distribution
plan adopted with respect to such class pursuant to which account maintenance
and/or distribution fees are paid. Each class has different exchange privileges.
See "Shareholder Services--Exchange Privilege."     
 
  The Merrill Lynch Select Pricing (SM) System is used by more than 50 mutual
funds advised by MLAM or its affiliate, the Manager. Funds advised by MLAM or
the Manager are referred to herein as "MLAM-advised mutual funds."
 
  The Fund has entered into four separate distribution agreements with the
Distributor in connection with the continuous offering of each class of shares
of the Fund (the "Distribution Agreements"). The Distribution Agreements
obligate the Distributor to pay certain expenses in connection with the
offering of each class of shares of the Fund. After the prospectuses,
statements of additional information and periodic reports have been prepared,
set in type and mailed to shareholders, the Distributor pays for the printing
and distribution of copies thereof used in connection with the offering to
dealers and prospective investors. The Distributor also pays for other
supplementary sales literature and advertising costs. The Distribution
Agreements are subject to the same renewal requirements and termination
provisions as the Management Agreement described above.
 
INITIAL SALES CHARGE ALTERNATIVES--CLASS A AND CLASS D SHARES
   
  The gross sales charges for the sale of Class A shares for the year ended
July 31, 1993 were $113,436, of which the Distributor received $6,558 and
Merrill Lynch received $106,848. The gross sales charges for the sale of Class
A shares for the year ended July 31, 1994 were $93,697, of which the
Distributor received $8,083     
 
                                       20

and Merrill Lynch received $85,614. The gross sales charges for the sale of
Class A shares for the year ended July 31, 1995 were $16,482, of which the
Distributor received $1,289 and Merrill Lynch received $15,193. The gross sales
charges for the sale of Class D shares for the period October 21, 1994
(commencement of operations) to July 31, 1995 were $26,959, of which the
Distributor received $773 and Merrill Lynch received $26,186.     
 
  The term "purchase", as used in the Prospectus and this Statement of
Additional Information in connection with an investment in Class A and Class D
shares of the Fund, refers to a single purchase by an individual, or to
concurrent purchases, which in the aggregate are at least equal to the
prescribed amounts, by an individual, his spouse and their children under the
age of 21 years purchasing shares for his or their own account and to single
purchases by a trustee or other fiduciary purchasing shares for a single trust
estate or single fiduciary account although more than one beneficiary is
involved. The term "purchase" also includes purchases by any "company", as that
term is defined in the 1940 Act, but does not include purchases by any such
company which has not been in existence for at least six months or which has no
purpose other than the purchase of shares of the Fund or shares of other
registered investment companies at a discount; provided, however, that it shall
not include purchases by any group of individuals whose sole organizational
nexus is that the participants therein are credit cardholders of a company,
policyholders of an insurance company, customers of either a bank or broker-
dealer or clients of an investment adviser.
   
  Closed-End Investment Option. Class A shares of the Fund and other MLAM-
advised mutual funds ("Eligible Class A shares") are offered at net asset value
to shareholders of certain closed-end funds advised by the Manager or MLAM who
purchased such closed-end fund shares prior to October 21, 1994 and wish to
reinvest the net proceeds of a sale of their closed-end fund shares of common
stock in Eligible Class A shares, if the conditions set forth below are
satisfied. Alternatively, closed-end fund shareholders who purchased such
shares on or after October 21, 1994 and wish to reinvest the net proceeds from
a sale of their closed-end fund shares are offered Class A shares (if eligible
to buy Class A shares) or Class D shares of the Fund and other MLAM-advised
mutual funds ("Eligible Class D Shares"), if the following conditions are met.
First, the sale of closed-end fund shares must be made through Merrill Lynch,
and the net proceeds therefrom must be immediately reinvested in Eligible Class
A or Class D shares. Second, the closed-end fund shares must either have been
acquired in the initial public offering or be shares representing dividends
from shares of common stock acquired in such offering. Third, the closed-end
fund shares must have been continuously maintained in a Merrill Lynch
securities account. Fourth, there must be a minimum purchase of $250 to be
eligible for the investment option. Class A shares of the Fund are offered at
net asset value to shareholders of Merrill Lynch Senior Floating Rate Fund,
Inc. ("Senior Floating Rate Fund") who wish to reinvest the net proceeds from a
sale of certain of their shares of common stock of Senior Floating Rate Fund in
shares of the Fund. In order to exercise this investment option, Senior
Floating Rate Fund shareholders must sell their Senior Floating Rate Fund
shares to the Senior Floating Rate Fund in connection with a tender offer
conducted by the Senior Floating Rate Fund and reinvest the proceeds
immediately in the Fund. This investment option is available only with respect
to the proceeds of Senior Floating Rate Fund shares as to which no Early
Withdrawal Charge (as defined in the Senior Floating Rate Fund prospectus) is
applicable. Purchase orders from Senior Floating Rate Fund shareholders wishing
to exercise this investment option will be accepted only on the day that the
related Senior Floating Rate Fund tender offer terminates and will be effected
at the net asset value of the Fund on such day. Similarly, Class D shares of
the Fund are offered at

net asset value to shareholders of Merrill Lynch Municipal Strategy Fund, Inc.
("Municipal Strategy Fund") who wish to purchase shares of the Fund with the
net proceeds from a sale of certain of their shares of common stock of
Municipal Strategy Fund pursuant to a tender offer by Municipal Strategy Fund.
This investment option is available only with respect to the proceeds of
Municipal Strategy Fund shares as to which no CDSC (as defined in the Municipal
Strategy Fund prospectus) is applicable.     
 
REDUCED INITIAL SALES CHARGES
 
  Right of Accumulation. Reduced sales charges are applicable through a right
of accumulation under which eligible investors are permitted to purchase shares
of the Fund subject to an initial sales charge at the offering price applicable
to the total of (a) the public offering price of the shares then being
purchased plus (b) an amount equal to the then current net asset value or cost,
whichever is higher, of the purchaser's combined holdings of all classes of
shares of the Fund and of other MLAM-advised mutual funds. For any such right
of accumulation to be made available, the Distributor must be provided at the
time of purchase, by the purchaser or the purchaser's securities dealer, with
sufficient information to permit confirmation of qualification. Acceptance of
the purchase order is subject to such confirmation. The right of accumulation
may be amended or terminated at any time. Shares held in the name of a nominee
or custodian under pension, profit-sharing, or other employee benefit plans may
not be combined with other shares to qualify for the right of accumulation.
 
  Letter of Intention. Reduced sales charges are applicable to purchases
aggregating $25,000 or more of the Class A or Class D shares of the Fund or any
other MLAM-advised mutual funds made within a 13-month period starting with the
first purchase pursuant to a Letter of Intention in the form provided in the
Prospectus. The Letter of Intention is available only to investors whose
accounts are maintained at the Fund's transfer agent. The Letter of Intention
is not available to employee benefit plans for which Merrill Lynch provides
plan participant recordkeeping services. The Letter of Intention is not a
binding obligation to purchase any amount of Class A or Class D shares.
However, its execution will result in the purchaser paying a lower sales charge
at the appropriate quantity purchase level. A purchase not originally made
pursuant to a Letter of Intention may be included under a subsequent Letter of
Intention executed within 90 days of such purchase if the Distributor is
informed in writing of this intent within such 90-day period. The value of
Class A and Class D shares of the Fund and of other MLAM-advised mutual funds
presently held, at cost or maximum offering price (whichever is higher), on the
date of the first purchase under the Letter of Intention, may be included as a
credit toward the completion of such Letter, but the reduced sales charge
applicable to the amount covered by such Letter will be applied only to new
purchases. If the total amount of shares does not equal the amount stated in
the Letter of Intention (minimum of $25,000), the investor will be notified and
must pay, within 20 days of the expiration of such Letter, the difference
between the sales charge on the Class A or Class D shares purchased at the
reduced rate and the sales charge applicable to the shares actually purchased
through the Letter. Class A or Class D shares equal to five percent of the
intended amount will be held in escrow during the 13-month period (while
remaining registered in the name of the purchaser) for this purpose. The first
purchase under the Letter of Intention must be at least five percent of the
dollar amount of such Letter. If a purchase during the term of such Letter
would otherwise be subject to a further reduced sales charge based on the right
for accumulation, the purchaser will be entitled on that purchase and
subsequent purchases to that further reduced percentage sales charge but there
will be no retroactive reduction of the sales charges on any previous purchase.
The value of any shares redeemed or otherwise
 
                                       22
<PAGE>
 
   
disposed of by the purchaser prior to termination or completion of the Letter
of Intention will be deducted from the total purchases made under such Letter.
An exchange from a MLAM-advised money market fund into the Fund that creates a
sales charge will count toward completing a new or existing Letter of Intention
from the Fund.     
   
  Employee Access Accounts (SM). Class A or Class D shares are offered at net
asset value to Employee Access Accounts available through employers that
provide employer sponsored retirement or savings plans that are eligible to
purchase such shares at net asset value. The initial minimum for such accounts
is $500, except that the initial minimum for shares purchased for such accounts
pursuant to the Automatic Investment Program is $50.     
 
  TMA (SM) Managed Trusts. Class A shares are offered at net asset value to
TMASM Managed Trusts to which Merrill Lynch Trust Company provides discretionary
trustee services at net asset value.
   
  Purchase Privileges of Certain Persons. Trustees of the Trust, members of the
Boards of other MLAM-advised investment companies, ML & Co. and its
subsidiaries (the term "subsidiaries", when used herein with respect to ML &
Co., includes MLAM, the Manager and certain other entities directly or
indirectly wholly-owned and controlled by ML & Co.) and their directors and
employees, and any trust, pension, profit-sharing or other benefit plan for
such persons, may purchase Class A shares of the Fund at net asset value.     
   
  Class D shares of the Fund are offered at net asset value, without sales
charge, to an investor who has a business relationship with a financial
consultant who joined Merrill Lynch from another investment firm within six
months prior to the date of purchase by such investor, if the following
conditions are satisfied: first, the investor must advise Merrill Lynch that it
will purchase Class D shares of the Fund with proceeds from a redemption of a
mutual fund that was sponsored by the financial consultant's previous firm and
was subject to a sales charge either at the time of purchase or on a deferred
basis; and second, the investor also must establish that such redemption had
been made within 60 days prior to the investment in the Fund, and the proceeds
from the redemption had been maintained in the interim in cash or a money
market fund.     
   
  Class D shares of the Fund are also offered at net asset value, without sales
charge, to an investor who has a business relationship with a Merrill Lynch
financial consultant and who has invested in a mutual fund sponsored by a non-
Merrill Lynch company for which Merrill Lynch has served as a selected dealer
and where Merrill Lynch has either received or given notice that such
arrangement will be terminated ("notice"), if the following conditions are
satisfied: first, the investor must purchase Class D shares of the Fund with
proceeds from a redemption of shares of such other mutual fund and the shares
of such other fund were subject to a sales charge either at the time of
purchase or on a deferred basis; and second, such purchase of Class D shares
must be made within 90 days after such notice.     
   
  Class D shares of the Fund are offered at net asset value, without a sales
charge, to an investor who has a business relationship with a Merrill Lynch
financial consultant and who has invested in a mutual fund for which Merrill
Lynch has not served as a selected dealer if the following conditions are
satisfied: first, the investor must advise Merrill Lynch that it will purchase
Class D shares of the Fund with proceeds from the redemption of shares of such
other mutual fund and that such shares have been outstanding for a period of
    
                                       23
<PAGE>
 
   
no less than six months; and second, such purchase of Class D shares must be
made within 60 days after the redemption and the proceeds from the redemption
must be maintained in the interim in cash or a money market fund.     
 
  Acquisition of Certain Investment Companies. The public offering price of
Class D shares may be reduced to the net asset value per Class D share in
connection with the acquisition of the assets of or merger or consolidation
with a personal holding company or a public or private investment company. The
value of the assets or company acquired in a tax-free transaction may be
adjusted in appropriate cases to reduce possible adverse tax consequences to
the Fund which might result from an acquisition of assets having net unrealized
appreciation which is disproportionately higher at the time of acquisition than
the realized or unrealized appreciation of the Fund. The issuance of Class D
shares for consideration other than cash is limited to bona fide
reorganizations, statutory mergers or other acquisitions of portfolio
securities which (i) meet the investment objectives and policies of the Fund;
(ii) are acquired for investment and not for resale (subject to the
understanding that the disposition of the Fund's portfolio securities shall at
all times remain within its control); and (iii) are liquid securities, the
value of which is readily ascertainable, which are not restricted as to
transfer either by law or liquidity of market (except that the Fund may acquire
through such transactions restricted or illiquid securities to the extent the
Fund does not exceed the applicable limits on acquisition of such securities
set forth under "Investment Objective and Policies" herein).
       
DISTRIBUTION PLANS
 
  Reference is made to "Purchase of Shares--Distribution Plans" in the
Prospectus for certain information with respect to the separate distribution
plans for Class B, Class C and Class D shares pursuant to Rule 12b-1 under the
1940 Act (each a "Distribution Plan") with respect to the account maintenance
and/or distribution fees paid by the Fund to the Distributor with respect to
such classes.
 
  Payments of account maintenance fees and/or distribution fees are subject to
the provisions of Rule 12b-1 under the 1940 Act. Among other things, each
Distribution Plan provides that the Distributor shall provide and the Trustees
shall review quarterly reports of the disbursement of the account maintenance
fees and/or distribution fees paid to the Distributor. In their consideration
of each Distribution Plan, the Trustees must consider all factors they deem
relevant, including information as to the benefits of the Distribution Plan to
the Fund and its related class of shareholders. Each Distribution Plan further
provides that, so long as the Distribution Plan remains in effect, the
selection and nomination of Trustees who are not "interested persons" of the
Trust, as defined in the 1940 Act (the "Independent Trustees"), shall be
committed to the discretion of the Independent Trustees then in office. In
approving each Distribution Plan in accordance with Rule 12b-1, the Independent
Trustees concluded that there is reasonable likelihood that each Distribution
Plan will benefit the Fund and its related class of shareholders. Each
Distribution Plan can be terminated at any time, without penalty, by the vote
of a majority of the Independent Trustees or by the vote of the holders of a
majority of the outstanding related class of voting securities of the Fund. A
Distribution Plan cannot be amended to increase materially the amount to be
spent by the Fund without the approval by the related class of shareholders,
and all material amendments are required to be approved by the vote of
Trustees, including a majority of the Independent Trustees who have no direct
or indirect financial interest in such Distribution Plan, cast in person at a
meeting called for that purpose. Rule 12b-1 further requires that the Trust
preserve copies of each Distribution Plan and any report made pursuant to such
plan for a period of not less than six years from the date of such Distribution
Plan or such report, the first two years in an easily accessible place.

LIMITATIONS ON THE PAYMENT OF DEFERRED SALES CHARGES
 
  The maximum sales charge rule in the Rules of Fair Practice of the National
Association of Securities Dealers, Inc. ("NASD") imposes a limitation on
certain asset-based sales charges such as the distribution fee and the CDSC
borne by the Class B and Class C shares but not the account maintenance fee.
The maximum sales charge rule is applied separately to each class. As
applicable to the Fund, the maximum sales charge rule limits the aggregate of
distribution fee payments and CDSCs payable by the Fund to (1) 6.25% of
eligible gross sales of Class B shares and Class C shares, computed separately
(defined to exclude shares issued pursuant to dividend reinvestments and
exchanges), plus (2) interest on the unpaid balance for the respective class,
computed separately, at the prime rate plus 1% (the unpaid balance being the
maximum amount payable minus amounts received from the payment of the
distribution fee and the CDSC). In connection with the Class B shares, the
Distributor has voluntarily agreed to waive interest charges on the unpaid
balance in excess of 0.50% of eligible gross sales. Consequently, the maximum
amount payable to the Distributor (referred to as the "voluntary maximum") in
connection with the Class B shares is 6.75% of eligible gross sales. The
Distributor retains the right to stop waiving the interest charges at any
time. To the extent payments would exceed the voluntary maximum, the Fund will
not make further payments of the distribution fee with respect to Class B
shares, and any CDSCs will be paid to the Fund rather than to the Distributor;
however, the Fund will continue to make payments of the account maintenance
fee. In certain circumstances the amount payable pursuant to the voluntary
maximum may exceed the amount payable under the NASD formula. In such
circumstances payment in excess of the amount payable under the NASD formula
will not be made.
   
  The following table sets forth comparative information as of July 31, 1995
with respect to the Class B and Class C shares of the Fund indicating the
maximum allowable payments that can be made under the NASD maximum sales
charge rule and, with respect to the Class B shares, the Distributor's
voluntary maximum for the period August 31, 1990 (commencement of operations)
to July 31, 1995.

                              REDEMPTION OF SHARES
 
  Reference is made to "Redemption of Shares" in the Prospectus for certain
information as to the redemption and repurchase of Fund shares.
 
  The right to redeem shares or to receive payment with respect to any such
redemption may be suspended only for any period during which trading on the New
York Stock Exchange is restricted as determined by the Commission or such
Exchange is closed (other than customary weekend and holiday closings), for any
period during which an emergency exists as defined by the Commission as a
result of which disposal of portfolio securities or determination of the net
asset value of the Fund is not reasonably practicable, and for such other
periods as the Commission may by order permit for the protection of
shareholders of the Fund.
   
DEFERRED SALES CHARGES--CLASS B AND CLASS C SHARES     
   
  As discussed in the Prospectus under "Purchase of Shares--Deferred Sales
Charge Alternatives--Class B and Class C Shares," while Class B shares redeemed
within four years of purchase are subject to a CDSC under most circumstances,
the charge is waived on redemptions of Class B shares following the death or
disability of a Class B shareholder. Redemptions for which the waiver applies
are any partial or complete redemption following the death or disability (as
defined in the Internal Revenue Code of 1986, as amended (the "Code")) of a
Class B shareholder (including one who owns the Class B shares as joint tenant
with his or her spouse), provided the redemption is requested within one year
of the death or initial determination of disability. For the fiscal years ended
July 31, 1993, 1994, and 1995 the Distributor received CDSCs of $114,196,
$204,747 and $302,369, respectively, all of which was paid to Merrill Lynch.
For the period October 21, 1994 (commencement of operations) to July 31, 1995,
the Distributor received CDSCs of $621 with respect to redemptions of Class C
shares, all of which was paid to Merrill Lynch.     
   
  The CDSC is also waived for any Class B shares that were acquired and held at
the time of redemption by Employee Access Accounts available through employers
that provide Eligible 401(k) Plans. The initial minimum for such accounts is
$500, except that the initial minimum for shares purchased for such accounts
pursuant to the Automatic Investment Program is $50.     
 
                             PORTFOLIO TRANSACTIONS
 
  Reference is made to "Investment Objective and Policies--Other Investment
Policies and Practices" in the Prospectus.
   
  Under the 1940 Act, persons affiliated with the Trust are prohibited from
dealing with the Fund as a principal in the purchase and sale of securities
unless such trading is permitted by an exemptive order issued by the
Commission. Since over-the-counter transactions are usually principal
transactions, affiliated persons of the Trust, including Merrill Lynch, may not
serve as dealer in connection with transactions with the Fund. The Trust has
obtained an exemptive order permitting it to engage in certain principal
transactions with Merrill Lynch involving high quality short-term municipal
bonds subject to certain conditions. For the year ended July 31, 1993, the Fund
engaged in two transactions pursuant to such order for an aggregate market
value of $1,003,147. For the year ended July 31, 1994, the Fund engaged in one
transaction pursuant to such     
 
                                       26
<PAGE>
 
   
order for an aggregate market value of $602,352. For the year ended July 31,
1995, the Fund engaged in no transactions pursuant to such order. The Trust has
applied for an exemptive order permitting it to, among other things, (i)
purchase high quality tax-exempt securities from Merrill Lynch when Merrill
Lynch is a member of an underwriting syndicate and (ii) purchase tax-exempt
securities from and sell tax-exempt securities to Merrill Lynch in secondary
market transactions. Affiliated persons of the Trust may serve as broker for
the Fund in over-the-counter transactions conducted on an agency basis. Certain
court decisions have raised questions as to the extent to which investment
companies should seek exemptions under the 1940 Act in order to seek to
recapture underwriting and dealer spreads from affiliated entities. The
Trustees have considered all factors deemed relevant, and have made a
determination not to seek such recapture at this time. The Trustees will
reconsider this matter from time to time.     
   
  As a non-fundamental restriction, the Trust will prohibit the purchase or
retention by the Fund of the securities of any issuer if the officers and
Trustees of the Trust, the officers and general partner of the Manager, the
directors of such general partner or the officers and directors of any
subsidiary thereof each owning beneficially more than one-half of one per cent
of the securities of such issuer own in the aggregate more than five percent of
the securities of such issuer. In addition, under the 1940 Act, the Fund may
not purchase securities from any underwriting syndicate of which Merrill Lynch
is a member except pursuant to an exemptive order or rules adopted by the
Commission. Rule 10f-3 under the 1940 Act sets forth conditions under which the
Fund may purchase municipal bonds in such transactions. The rule sets forth
requirements relating to, among other things, the terms of an issue of
municipal bonds purchased by the Fund, the amount of municipal bonds which may
be purchased in any one issue and the assets of the Fund which may be invested
in a particular issue.     
 
  The Fund does not expect to use any particular dealer in the execution of
transactions but, subject to obtaining the best net results, dealers who
provide supplemental investment research (such as information concerning tax-
exempt securities, economic data and market forecasts) to the Manager may
receive orders for transactions by the Fund. Information so received will be in
addition to and not in lieu of the services required to be performed by the
Manager under its Management Agreement and the expenses of the Manager will not
necessarily be reduced as a result of the receipt of such supplemental
information.
 
  The Trust has no obligation to deal with any broker in the execution of
transactions for the Fund's portfolio securities. In addition, consistent with
the Rules of Fair Practice of the NASD and policies established by the Trustees
of the Trust the Manager may consider sales of shares of the Fund as a factor
in the selection of brokers or dealers to execute portfolio transactions for
the Fund.
 
  Generally, the Fund does not purchase securities for short-term trading
profits. However, the Fund may dispose of securities without regard to the time
they have been held when such action, for defensive or other reasons, appears
advisable to its Manager. While it is not possible to predict turnover rates
with any certainty, at present it is anticipated that the Fund's annual
portfolio turnover rate, under normal circumstances after the Fund's portfolio
is invested in accordance with its investment objective, will be less than
100%. (The portfolio turnover rate is calculated by dividing the lesser of
purchases or sales of portfolio securities for the particular fiscal year by
the monthly average of the value of the portfolio securities owned by the Fund
during the particular fiscal year. For purposes of determining this rate, all
securities whose maturities at the time of
 
                                       27
<PAGE>
 
   
acquisition are one year or less are excluded.) The portfolio turnover for the
fiscal years ended July 31, 1993, 1994 and 1995 were 9.69%, 37.73% and 59.17%,
respectively.     
 
  Section 11(a) of the Securities Exchange Act of 1934, as amended, generally
prohibits members of the U.S. national securities exchanges from executing
exchange transactions for their affiliates and institutional accounts which
they manage unless the member (i) has obtained prior express authorization from
the account to effect such transactions, (ii) at least annually furnishes the
account with a statement setting forth the aggregate compensation received by
the member in effecting such transactions, and (iii) complies with any rules
the Commission has prescribed with respect to the requirements of clauses (i)
and (ii). To the extent Section 11(a) would apply to Merrill Lynch acting as a
broker for the Fund in any of its portfolio transactions executed on any such
securities exchange of which it is a member, appropriate consents have been
obtained from the Fund and annual statements as to aggregate compensation will
be provided to the Fund.
 
                        DETERMINATION OF NET ASSET VALUE
   
  The net asset value of the shares of all classes of the Fund is determined
once daily, Monday through Friday, as of 15 minutes after the close of business
on the New York Stock Exchange (generally, 4:00 P.M., New York time) on each
day during which the New York Stock Exchange is open for trading. The New York
Stock Exchange is not open on New Year's Day, Presidents' Day, Good Friday,
Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day.
Net asset value per share is computed by dividing the sum of the value of the
securities held by the Fund plus any cash or other assets minus all liabilities
by the total number of shares outstanding at such time, rounded to the nearest
cent. Expenses, including the fees payable to the Manager and the Distributor,
are accrued daily. The per share net asset value of the Class B, Class C, and
Class D shares generally will be lower than the per share net asset value of
the Class A shares, reflecting the higher daily expense accruals of the account
maintenance, distribution and higher transfer agency fees applicable with
respect to the Class B and Class C shares and the daily expense accruals of the
account maintenance fees applicable with respect to Class D shares. Moreover
the per share net asset value of the Class B and Class C shares generally will
be lower than the per share net asset value of its Class D shares, reflecting
the daily expense accruals of the distribution fees and higher transfer agency
fees applicable with respect to the Class B and Class C shares of the Fund. It
is expected, however, that the per share net asset value of the four classes
eventually will tend to converge (although not necessarily meet) immediately
after the payment of dividends, which will differ by approximately the amount
of the expense accrual differentials between the classes.     
 
  The Municipal Bonds and other portfolio securities in which the Fund invests
are traded primarily in over-the-counter municipal bond and money markets and
are valued at the last available bid price in the over-the-counter market or on
the basis of yield equivalents as obtained from one or more dealers that make
markets in the securities. One bond is the "yield equivalent" of another bond
when, taking into account market price, maturity, coupon rate, credit rating
and ultimate return of principal, both bonds will theoretically produce an
equivalent return to the bondholder. Financial futures contracts and options
thereon, which are traded on exchanges, are valued at their settlement prices
as of the close of such exchanges. Short-term investments with a remaining
maturity of 60 days or less are valued on an amortized cost basis, which
approximates market value. Securities and assets for which market quotations
are not readily available are
 
                                       28
<PAGE>
 
valued at fair value as determined in good faith by or under the direction of
the Trustees of the Trust, including valuations furnished by a pricing service
retained by the Trust, which may utilize a matrix system for valuations. The
procedures of the pricing service and its valuations are reviewed by the
officers of the Trust under the general supervision of the Trustees.
 
                              SHAREHOLDER SERVICES
 
  The Trust offers a number of shareholder services described below which are
designed to facilitate investment in shares of the Fund. Full details as to
each of such services and copies of the various plans described below can be
obtained from the Trust, the Distributor or Merrill Lynch.
 
INVESTMENT ACCOUNT
   
  Each shareholder whose account is maintained at the Transfer Agent has an
Investment Account and will receive statements, at least quarterly, from the
Transfer Agent. These statements will serve as transaction confirmations for
automatic investment purchases and the reinvestment of ordinary income
dividends and long-term capital gain distributions. The statements will also
show any other activity in the account since the preceding statement.
Shareholders also will receive separate transaction confirmations for each
purchase or sale transaction other than automatic investment purchases and the
reinvestment of ordinary income dividends and long-term capital gain
distributions. A shareholder may make additions to his or her Investment
Account at any time by mailing a check directly to the Transfer Agent.     
 
  Share certificates are issued only for full shares and only upon the specific
request of a shareholder who has an Investment Account. Issuance of
certificates representing all or only part of the full shares in an Investment
Account may be requested by a shareholder directly from the Transfer Agent.
   
  Shareholders considering transferring their Class A shares from Merrill Lynch
to another brokerage firm or financial institution should be aware that, if the
firm to which the Class A or Class D shares are to be transferred will not take
delivery of shares of the Fund, a shareholder either must redeem the Class A or
Class D shares (paying any applicable CDSC) so that the cash proceeds can be
transferred to the account at the new firm or such shareholder must continue to
maintain an Investment Account at the Transfer Agent for those Class A or Class
D shares. Shareholders interested in transferring their Class B or Class C
shares from Merrill Lynch and who do not wish to have an Investment Account
maintained for such shares at the Transfer Agent may request their new
brokerage firm to maintain such shares in an account registered in the name of
the brokerage firm for the benefit of the shareholder at the Transfer Agent. If
the new brokerage firm is willing to accommodate the shareholder in this
manner, the shareholder must request that he or she be issued certificates for
his or her shares, and then must turn the certificates over to the new firm for
re-registration as described in the preceding sentence.     
 
AUTOMATIC INVESTMENT PLANS
 
  A shareholder may make additions to an Investment Account at any time by
purchasing Class A shares (if an eligible Class A investor as described in the
Prospectus) or Class B, Class C or Class D shares at the
 
                                       29
<PAGE>
 
   
applicable public offering price either through the shareholder's securities
dealer, or by mail directly to the Transfer Agent, acting as agent for such
securities dealers. Voluntary accumulation also can be made through a service
known as the Automatic Investment Plan whereby the Fund is authorized through
pre-authorized checks or automated clearing house debits of $50 or more to
charge the regular bank account of the shareholder on a regular basis to
provide systematic additions to the Investment Account of such shareholder. The
Fund's Automatic Investment Plan is not available to shareholders whose shares
are held in brokerage accounts with Merrill Lynch. Alternatively, investors who
maintain CMA (R) or CBA (R) accounts may arrange to have periodic investments
made in the Fund in the CMA (R) or CBA (R) account or in certain related
accounts, in amounts of $100 or more through the CMA (R)/CBA (R) Automated
Investment Program.     
 
AUTOMATIC REINVESTMENT OF DIVIDENDS AND CAPITAL GAINS DISTRIBUTIONS
 
  Unless specific instructions are given as to the method of payment of
dividends and capital gains distributions, dividends and distributions will be
reinvested automatically in additional shares of the Fund. Such reinvestment
will be at the net asset value of shares of the Fund as of the close of
business on the monthly payment date for such dividends and distributions.
Shareholders may elect in writing to receive either their income dividends or
capital gains distributions, or both, in cash, in which event payment will be
mailed or direct deposited on or about the payment date. Cash payments can also
be direct deposited to the shareholder's bank account.
 
  Shareholders may, at any time, notify the Transfer Agent in writing or by
telephone (1-800-MER-FUND) that they no longer wish to have their dividends
and/or capital gains distributions reinvested in shares of the Fund or vice
versa and, commencing ten days after the receipt by the Transfer Agent of such
notice, such instructions will be effected.
   
SYSTEMATIC WITHDRAWAL PLANS--CLASS A AND CLASS D SHARES     
 
  A Class A or Class D shareholder may elect to make systematic withdrawals
from an Investment Account on either a monthly or quarterly basis as provided
below. Quarterly withdrawals are available for shareholders who have acquired
Class A or Class D shares of the Fund having a value, based on cost or the
current offering price, of $5,000 or more, and monthly withdrawals are
available for shareholders with Class A or Class D shares with such a value of
$10,000 or more.
   
  At the time of each withdrawal payment, sufficient Class A or Class D shares
are redeemed from those on deposit in the shareholder's account to provide the
withdrawal payment specified by the shareholder. The shareholder may specify
either a dollar amount or a percentage of the value of his Class A or Class D
shares. Redemptions will be made at net asset value as determined 15 minutes
after the close of business on the New York Stock Exchange (generally, 4:00
P.M., New York time) on the 24th day of each month or the 24th day of the last
month of each quarter, whichever is applicable. If the Exchange is not open for
business on such date, the Class A or Class D shares will be redeemed at the
close of business on the following business day. The check for the withdrawal
payment will be mailed, or the direct deposit for the withdrawal payment will
be made, on the next business day following redemption. When a shareholder is
making systematic withdrawals, dividends and distributions on all Class A or
Class D shares in the Investment Account are reinvested automatically in the
Fund's Class A or Class D shares, respectively. A shareholder's Systematic
Withdrawal Plan may be terminated at any time, without charge or penalty, by
the shareholder, the Trust,     
 
                                       30
<PAGE>
 
the Transfer Agent or the Distributor. Withdrawal payments should not be
considered as dividends, yield or income. Each withdrawal is a taxable event.
If periodic withdrawals continuously exceed reinvested dividends, the
shareholder's original investment may be reduced correspondingly. Purchases of
additional Class A or Class D shares concurrent with withdrawals are ordinarily
disadvantageous to the shareholder because of sales charges and tax
liabilities. The Trust will not knowingly accept purchase orders for Class A or
Class D shares of the Fund from investors who maintain a Systematic Withdrawal
Plan unless such purchase is equal to at least one year's scheduled withdrawals
or $1,200, whichever is greater. Periodic investments may not be made into an
Investment Account in which the shareholder has elected to make systematic
withdrawals.
   
  Alternatively, a Class A or Class D shareholder whose shares are held within
a CMA (R) or CBA (R) account may elect to have shares redeemed on a monthly,
bimonthly, quarterly, semiannual or annual basis through the CMA (R)/CBA (R)
Systematic Redemption Program. The minimum fixed dollar amount redeemable is
$25. The proceeds of systematic redemptions will be posted to the shareholder's
account five business days after the date the shares are redeemed. Monthly
systematic redemptions will be made at net asset value on the first Monday of
each month, bimonthly systematic redemptions will be made at net asset value on
the first Monday of every other month, and quarterly, semiannual or annual
redemptions are made at net asset value on the first Monday of months selected
at the shareholder's option. If the first Monday of the month is a holiday, the
redemption will be processed at net asset value on the next business day. The
CMA (R)/CBA (R) Systematic Redemption Program is not available if Fund shares
are being purchased within the account pursuant to the CMA (R)/CBA (R)
Automated Investment Program. For more information on the CMA (R)/CBA (R)
Systematic Redemption Program eligible shareholders should contact their
Financial Consultant.     
 
EXCHANGE PRIVILEGE
   
  Shareholders of each class of shares of the Fund have an exchange privilege
with certain other MLAM-advised mutual funds listed below. Under the Merrill
Lynch Select PricingSM System, Class A shareholders may exchange Class A shares
of the Fund for Class A shares of a second MLAM-advised mutual fund if the
shareholder holds any Class A shares of the second fund in his account in which
the exchange is made at the time of the exchange or is otherwise eligible to
purchase Class A shares of the second fund. If the Class A shareholder wants to
exchange Class A shares for shares of a second MLAM-advised mutual fund, and
the shareholder does not hold Class A shares of the second fund in his account
at the time of the exchange and is not otherwise eligible to acquire Class A
shares of the second fund, the shareholder will receive Class D shares of the
second fund as a result of the exchange. Class D shares also may be exchanged
for Class A shares of a second MLAM-advised mutual fund at any time as long as,
at the time of the exchange, the shareholder holds Class A shares of the second
fund in the account in which the exchange is made or is otherwise eligible to
purchase Class A shares of the second fund. Class B, Class C and Class D shares
are exchangeable with shares of the same class of other MLAM-advised mutual
funds. For purposes of computing the CDSC that may be payable upon a
disposition of the shares acquired in the exchange, the holding period for the
previously owned shares of the Fund is "tacked" to the holding period of the
newly acquired shares of the other Fund as more fully described below. Class A,
Class B, Class C and Class D shares are also exchangeable for shares of certain
MLAM-advised money market funds specifically designated below as available for
exchange by holders of Class A, Class B, Class C or Class D shares. Shares with
a net asset value of at least     
 
                                       31
<PAGE>
 
$100 are required to qualify for the exchange privilege, and any shares
utilized in an exchange must have been held by the shareholder for 15 days. It
is contemplated that the exchange privilege may be applicable to other new
mutual funds whose shares may be distributed by the Distributor.
   
  Exchanges of Class A or Class D shares outstanding ("outstanding Class A or
Class D shares") for Class A or Class D shares of another MLAM-advised mutual
fund ("new Class A or Class D shares") are transacted on the basis of relative
net asset value per Class A or Class D share, respectively, plus an amount
equal to the difference, if any, between the sales charge previously paid on
the outstanding Class A or Class D shares and the sales charge payable at the
time of the exchange on the new Class A or Class D shares. With respect to
outstanding Class A or Class D shares as to which previous exchanges have
taken place, the "sales charge previously paid" shall include the aggregate of
the sales charges paid with respect to such Class A or Class D shares in the
initial purchase and any subsequent exchange. Class A or Class D shares issued
pursuant to dividend reinvestment are sold on a no-load basis in each of the
funds offering Class A or Class D shares. For purposes of the exchange
privilege, Class A and Class D shares acquired through dividend reinvestment
shall be deemed to have been sold with a sales charge equal to the sales
charge previously paid on the Class A or Class D shares on which the dividend
was paid. Based on this formula, Class A and Class D shares generally may be
exchanged into the Class A or Class D shares of the other funds or into shares
of the Class A and Class D money market funds without a sales charge.     
   
  In addition, each of the funds with Class B and Class C shares outstanding
("outstanding Class B or Class C shares") offers to exchange its outstanding
Class B or Class C shares for Class B or Class C shares, respectively, of
other MLAM-advised mutual funds ("new Class B or Class C shares") on the basis
of relative net asset value per Class B or Class C share, without the payment
of any contingent deferred sales load that might otherwise be due on
redemption of the outstanding shares. Class B shareholders of the Fund
exercising the exchange privilege will continue to be subject to the Fund's
CDSC schedule if such schedule is higher than the deferred sales charge
schedule relating to the new Class B shares acquired through use of the
exchange privilege. In addition, Class B shares of the Fund acquired through
use of the exchange privilege will be subject to the Fund's CDSC schedule if
such schedule is higher than the CDSC schedule relating to the Class B shares
of the Fund from which the exchange has been made. For purposes of computing
the sales load that may be payable on a disposition of the new Class B or
Class C shares, the holding period for the outstanding Class B or Class C
shares is "tacked" to the holding period of the new Class B or Class C shares.
For example, an investor may exchange Class B shares of the Fund for those of
Merrill Lynch Special Value Fund, Inc. ("Special Value Fund") after having
held the Fund's Class B shares for two and a half years. The 2% CDSC that
generally would apply to a redemption would not apply to the exchange. Three
years later the investor may decide to redeem the Class B shares of Special
Value Fund and receive cash. There will be no CDSC due on this redemption,
since by "tacking" the two and a half year holding period of the Fund's Class
B shares to the three year holding period for the Special Value Fund Class B
shares, the investor will be deemed to have held the new Class B shares for
more than five years.     
 
  Shareholders also may exchange shares of the Fund into shares of a money
market fund advised by the Manager or its affiliates, but the period of time
that Class B or Class C shares are held in a money market fund will not count
towards satisfaction of the holding period requirement for purposes of
reducing the CDSC or, with respect to Class B shares, towards satisfaction of
the conversion period. However, shares of a money market fund which were
acquired as a result of an exchange for Class B or Class C shares of the Fund
may,
 
                                      32
<PAGE>
 
   
in turn, be exchanged back into Class B or Class C shares, respectively, of any
fund offering such shares, in which event the holding period for Class B or
Class C shares of the fund will be aggregated with previous holding periods for
purposes of reducing the CDSC. Thus, for example, an investor may exchange
Class B shares of the Fund for shares of Merrill Lynch Institutional Fund
("Institutional Fund") after having held the Class B shares for two and a half
years and three years later decide to redeem the shares of Institutional Fund
for each. At the time of this redemption, the 2% CDSC that would have been due
had the Class B shares of the Fund been redeemed for cash rather than exchanged
for shares of Institutional Fund will be payable. If, instead of such
redemption the shareholder exchanged such shares for Class B shares of a fund
which the shareholder continued to hold for an additional two and a half years,
any subsequent redemption will not incur a CDSC.     
 
  Set forth below is a description of the investment objectives of the other
funds into which exchanges can be made:

  Before effecting an exchange, shareholders should obtain a currently
effective prospectus of the fund into which the exchange is to be made.
 
  To exercise the exchange privilege, shareholders should contact their Merrill
Lynch financial consultant, who will advise the Fund of the exchange.
Shareholders of the Fund, and shareholders of the other funds described above
with shares for which certificates have not been issued, may exercise the
exchange privilege by wire through their securities dealers. The Fund reserves
the right to require a properly completed Exchange Application. This exchange
privilege may be modified or terminated at any time in accordance with the
rules of the Commission. The Fund reserves the right to limit the number of
times an investor may exercise the exchange privilege. Certain funds may
suspend the continuous offering of their shares to the general public at any
time and may thereafter resume such offering from time to time. The exchange
privilege is available only to U.S. shareholders in states where the exchange
legally may be made.
 
                            DISTRIBUTIONS AND TAXES
 
  The Trust intends to continue to qualify the Fund for the special tax
treatment afforded regulated investment companies ("RICs") under the Internal
Revenue Code of 1986, as amended (the "Code"). If it so qualifies, in any
taxable year in which it distributes at least 90% of its taxable net income and
90% of its tax-exempt net income (see below), the Fund (but not its
shareholders) will not be subject to Federal income tax to the extent that it
distributes its net investment income and net realized capital gains. The Trust
intends to cause the Fund to distribute substantially all of such income.
 
                                       44
<PAGE>
 
   
  As discussed in the Fund's Prospectus, the Trust has established other series
in addition to the Fund (together with the Fund, the "Series"). Each Series of
the Trust is treated as a separate corporation for Federal income tax purposes.
Each Series therefore is considered to be a separate entity in determining its
treatment under the rules for RICs described in the Prospectus. Losses in one
Series do not offset gains in another Series, and the requirements (other than
certain organizational requirements) for qualifying for RIC status are
determined for each Series at the Series level rather than at the Trust level.
    
  The Code requires a RIC to pay a nondeductible 4% excise tax to the extent
the RIC does not distribute, during each calendar year, 98% of its ordinary
income, determined on a calendar year basis, and 98% of its capital gains,
determined, in general, on an October 31 year-end, plus certain undistributed
amounts from previous years. The required distributions, however, are based
only on the taxable income of a RIC. The excise tax, therefore, generally will
not apply to the tax-exempt income of a RIC, such as the Fund, that pays
exempt-interest dividends.
   
  The Trust intends to qualify the Fund to pay "exempt-interest dividends" as
defined in Section 852(b)(5) of the Code. Under such section if, at the close
of each quarter of the Fund's taxable year, at least 50% of the value of its
total assets consists of obligations exempt from Federal income tax ("tax-
exempt obligations") under Section 103(a) of the Code (relating generally to
obligations of a state or local governmental unit), the Fund shall be qualified
to pay exempt-interest dividends to its Class A, Class B, Class C and Class D
shareholders (together, the "shareholders"). Exempt-interest dividends are
dividends or any part thereof paid by the Fund which are attributable to
interest on tax-exempt obligations and designated by the Trust as exempt-
interest dividends in a written notice mailed to the Fund's shareholders within
60 days after the close of the Fund's taxable year. For this purpose, the Fund
will allocate interest from tax-exempt obligations (as well as ordinary income,
capital gains and tax preference items, discussed below) among the Class A,
Class B, Class C and Class D shareholders according to a method (which it
believes is consistent with the Commission's exemptive order permitting the
issuance and sale of multiple classes of shares) that is based on the gross
income allocable to Class A, Class B, Class C and Class D shareholders during
the taxable year or such other method as the Internal Revenue Service may
prescribe. To the extent that the dividends distributed to the Fund's
shareholders are derived from interest income exempt from Federal income tax
under Code Section 103(a) and are properly designated as exempt-interest
dividends, they will be excludable from a shareholder's gross income for
Federal income tax purposes. Exempt-interest dividends are included, however,
in determining the portion, if any, of a person's social security benefits and
railroad retirement benefits subject to Federal income taxes. Interest on
indebtedness incurred or continued to purchase or carry shares of a RIC paying
exempt-interest dividends, such as the Fund, will not be deductible by the
investor for Federal income tax purposes to the extent attributable to exempt-
interest dividends. Shareholders are advised to consult their tax advisers with
respect to whether exempt-interest dividends retain the exclusion under Code
Section 103(a) if a shareholder would be treated as a "substantial user" or
"related person" under Code Section 147(a) with respect to property financed
with the proceeds of an issue of "industrial development bonds" or "private
activity bonds", if any, held by the Fund.     
   
  The portion of the Fund's exempt-interest dividends paid from interest
received by the Fund from Pennsylvania Municipal Bonds also will be exempt from
Pennsylvania personal income tax. However, distributions attributable to
capital gains derived by the Fund as well as distributions derived from income
from investments other than Pennsylvania Municipal Bonds will be taxable for
purposes of the Pennsylvania     
 
                                       45
<PAGE>
 
   
personal income tax. In the case of residents of the City of Philadelphia,
distributions which are derived from interest on Pennsylvania Municipal Bonds
or which are designated as capital gain dividends for Federal income tax
purposes will be exempt from the Philadelphia School District investment income
tax. Shares of the Fund will be exempt from Pennsylvania county personal
property taxes to the extent the Fund's portfolio securities consist of
Pennsylvania Municipal Bonds on the annual assessment date. Shareholders
subject to income taxation by states other than Pennsylvania will realize a
lower after tax rate of return than Pennsylvania shareholders since the
dividends distributed by the Fund generally will not be exempt, to any
significant degree, from income taxation by such other states. The Trust will
inform shareholders annually regarding the portion of the Fund's distributions
which constitutes exempt-interest dividends and the portion which is exempt
from Pennsylvania personal income taxes. The Fund will allocate amounts exempt
from Pennsylvania personal income taxes among Class A, Class B, Class C and
Class D shareholders based on a method similar to that described above for
Federal income tax purposes.     
   
  It is unclear at this time whether an investment in the Fund by a corporate
shareholder will qualify as an exempt asset for purposes of apportionment of
the Pennsylvania capital stock/franchise tax. To the extent exempt-interest
dividends are excluded from taxable income for Federal corporate income tax
purposes (determined before net operating loss carryovers and special
deductions), they will not be subject to the Pennsylvania corporate net income
tax. An investment in or distributions from investment income and capital gains
of the Fund, including exempt-interest dividends, may be subject to state taxes
in states other than Pennsylvania (and, possibly, in Pennsylvania) and to local
taxes imposed by municipalities in states other than Pennsylvania (and,
possibly, municipalities in Pennsylvania). Accordingly, investors in the Fund,
including, in particular, corporate investors which may be subject to the
Pennsylvania capital stock/franchise tax, should consult their tax advisers
with respect to the application of such taxes to an investment in the Fund, to
the receipt of Fund dividends and to their Pennsylvania tax situation in
general.     
   
  To the extent that the Fund's distributions are derived from interest on its
taxable investments or from an excess of net short-term capital gains over net
long-term capital losses ("ordinary income dividends"), such distributions are
considered ordinary income for Federal income tax purposes. Distributions, if
any, from an excess of net long-term capital gains over net short-term capital
losses derived from the sale of securities or from certain transactions in
futures or options ("capital gain dividends") are taxable as long-term capital
gains for Federal income tax purposes, regardless of the length of time the
shareholder has owned Fund shares. Distributions by the Fund, whether from
exempt-interest income, ordinary income or capital gains, will not be eligible
for the dividends received deduction allowed to corporations under the Code.
       
  All or a portion of the Fund's gain from the sale or redemption of tax-exempt
obligations purchased at a market discount will be treated as ordinary income
rather than capital gain. This rule may increase the amount of ordinary income
dividends received by shareholders. Any loss upon the sale or exchange of Fund
shares held for six months or less will be treated as long-term capital loss to
the extent of capital gain dividends received by the shareholder. In addition,
such loss will be disallowed to the extent of any exempt-interest dividends
received by the shareholder. Distributions in excess of the Fund's earnings and
profits will first reduce the adjusted tax basis of a holder's shares and,
after such adjusted tax basis is reduced to zero, will constitute capital gains
to such holder (assuming the shares are held as a capital asset). If the Fund
pays a dividend in January which was declared in the previous October, November
or December to shareholders of record on a specified date in one of such
months, then such dividend will be treated for tax purposes as being paid by
the Fund and received by its shareholders on December 31 of the year in which
such dividend was declared.     
 
                                       46

  The Code subjects interest received on certain otherwise tax-exempt
securities to an alternative minimum tax. The alternative minimum tax applies
to interest received on "private activity bonds" issued after August 7, 1986.
Private activity bonds are bonds which, although tax-exempt, are used for
purposes other than those generally performed by governmental units and which
benefit non-governmental entities (e.g., bonds used for industrial development
or housing purposes). Income received on such bonds is classified as an item of
"tax preference", which could subject investors in such bonds, including
shareholders of the Fund, to an alternative minimum tax. The Fund will purchase
such "private activity bonds" and the Trust will report to shareholders within
60 days after the Fund's taxable year-end the portion of the Fund's dividends
declared during the year which constitutes an item of tax preference for
alternative minimum tax purposes. The Code further provides that corporations
are subject to an alternative minimum tax based, in part, on certain
differences between taxable income as adjusted for other tax preferences and
the corporation's "adjusted current earnings," which more closely reflect a
corporation's economic income. Because an exempt-interest dividend paid by the
Fund will be included in adjusted current earnings, a corporate shareholder may
be required to pay alternative minimum tax on exempt-interest dividends paid by
the Fund.     
          
  No gain or loss will be recognized for federal income tax purposes by Class B
shareholders on the conversion of their Class B shares into Class D shares. A
shareholder's basis in the Class D shares acquired will be the same as such
shareholder's basis in the Class B shares converted, and the holding period of
the acquired Class D shares will include the holding period for the converted
Class B shares.     
   
  If a shareholder exercises an exchange privilege within 90 days of acquiring
the shares, then the loss the shareholder can recognize on the exchange will be
reduced (or the gain increased) to the extent any sales charge paid to the Fund
on the exchanged shares reduces any sales charge such shareholder would have
owed upon purchase of the new shares in the absence of the exchange privilege.
Instead, such sales charge will be treated as an amount paid for the new
shares.     
 
  A loss realized on a sale or exchange of shares of the Fund will be
disallowed if other Fund shares are acquired (whether through the automatic
reinvestment of dividends or otherwise) within a 61-day period beginning 30
days before and ending 30 days after the date that the shares are disposed of.
In such a case, the basis of the shares acquired will be adjusted to reflect
the disallowed loss.
   
  Ordinary income dividends paid to shareholders who are nonresident aliens or
foreign entities will be subject to a 30% U.S. withholding tax under existing
provisions of the Code applicable to foreign individuals and entities unless a
reduced rate of withholding or a withholding exemption is provided under
applicable treaty law. Nonresident shareholders are urged to consult their own
tax advisers concerning the applicability of the U.S. withholding tax.     
   
  Under certain Code provisions, some shareholders may be subject to a 31%
withholding tax on certain ordinary income dividends and on capital gain
dividends and redemption payments ("backup withholding"). Generally,
shareholders subject to backup withholding will be those for whom no certified
taxpayer identification number is on file with the Trust or who, to the Trust's
knowledge, have furnished an incorrect number. When establishing an account, an
investor must certify under penalty of perjury that such number is correct and
that such investor is not otherwise subject to backup withholding.     
 
                                       47

  The Code provides that every person required to file a tax return must
include for information purposes on such return the amount of exempt-interest
dividends received from all sources (including the Fund) during the taxable
year.
 
ENVIRONMENTAL TAX
   
  The Code imposes a deductible tax (the "Environmental Tax") on a
corporation's modified alternative minimum taxable income (computed without
regard to the alternative tax net operating loss deduction and the deduction
for the Environmental Tax) at a rate of $12 per $10,000 (0.12%) of alternative
minimum taxable income in excess of $2,000,000. The Environmental Tax is
imposed for taxable years beginning after December 31, 1986 and before January
1, 1996. The Environmental Tax is imposed even if the corporation is not
required to pay an alternative minimum tax because the corporation's regular
income tax liability exceeds its minimum tax liability. The Code provides,
however, that a RIC, such as the Fund, is not subject to the Environmental Tax.
However, exempt-interest dividends paid by the Fund that create alternative
minimum taxable income for corporate shareholders (as described above) may
subject corporate shareholders of the Fund to the Environmental Tax.     
   
TAX TREATMENT OF OPTIONS AND FUTURES TRANSACTIONS     
   
  The Fund may purchase or sell municipal bond index futures contracts and
interest rate futures contracts on U.S. Government securities ("financial
futures contracts"). The Fund may also purchase and write call and put options
on such financial futures contracts. In general, unless an election is
available to the Fund or an exception applies, such options and financial
futures contracts that are "Section 1256 contracts" will be "marked to market"
for Federal income tax purposes at the end of each taxable year, i.e., each
such option or financial futures contract will be treated as sold for its
market value on the last day of the taxable year and any gain or loss
attributable to Section 1256 contracts will be 60% long-term and 40% short-term
capital gain or loss. Application of these rules to Section 1256 contracts held
by the Fund may alter the timing and character of distributions to
shareholders. The mark-to-market rules outlined above, however, will not apply
to certain transactions entered into by the Fund solely to reduce the risk of
changes in price or interest rates with respect to its investments.     
 
  Code Section 1092, which applies to certain "straddles", may affect the
taxation of the Fund's transactions in financial futures contracts and related
options. Under Section 1092, the Fund may be required to postpone recognition
for tax purposes of losses incurred in certain closing transactions in
financial futures contracts or the related options.
 
  One of the requirements for qualification as a RIC is that less than 30% of
the Fund's gross income be derived from gains from the sale or other
disposition of securities held for less than three months. Accordingly, the
Fund may be restricted in effecting closing transactions within three months
after entering into an option or financial futures contract.
 
PENNSYLVANIA TAXATION
 
  Under present Pennsylvania law, the Fund, as presently configured, is not
subject to Pennsylvania income taxes or Pennsylvania county personal property
taxes.

  The foregoing is a general and abbreviated summary of the applicable
provisions of the Code, Treasury regulations and applicable Pennsylvania income
tax laws presently in effect. For the complete provisions, reference should be
made to the pertinent Code sections, the Treasury regulations promulgated
thereunder and the applicable Pennsylvania tax laws. The Code and the Treasury
regulations, as well as the Pennsylvania income tax laws, are subject to change
by legislative, judicial or administrative action either prospectively or
retroactively.     
 
  Shareholders are urged to consult their own tax advisers regarding the
availability of any exemptions from state or local taxes (other than those

                                PERFORMANCE DATA
   
  From time to time the Fund may include its average annual total return and
other total return data, as well as yield and tax-equivalent yield in
advertisements or information furnished to present or prospective shareholders.
From time to time, the Fund may include the Fund's Morningstar risk-adjusted
performance ratings in advertisements or supplemental sales literature. Total
return, yield and tax-equivalent yield figures are based on the Fund's
historical performance and are not intended to indicate future performance.
Average annual total return, yield and tax-equivalent yield are determined
separately for Class A, Class B, Class C and Class D shares in accordance with
formulas specified by the Commission.     
 
  Average annual total return quotations for the specified periods are computed
by finding the average annual compounded rates of return (based on net
investment income and any realized and unrealized capital gains or losses on
portfolio investments over such periods) that would equate the initial amount
invested to the redeemable value of such investment at the end of each period.
Average annual total return is computed assuming all dividends and
distributions are reinvested and taking into account all applicable recurring
and nonrecurring expenses, including the maximum sales charge in the case of
the Class A and Class D shares and the CDSC that would be applicable to a
complete redemption of the investment at the end of the specified period in the
case of the Class B and Class C shares.
 
  The Fund also may quote annual, average annual and annualized total return
and aggregate total return performance data, both as a percentage and as a
dollar amount based on a hypothetical $1,000 investment, for various periods
other than those noted below. Such data will be computed as described above,
except that (1) as required by the periods of the quotations, actual annual,
annualized or aggregate data, rather than average annual data, may be quoted
and (2) the maximum applicable sales charges will not be included with respect
to annual or annualized rates of return calculations. Aside from the impact on
the performance data calculations of including or excluding the maximum
applicable sales charges, actual annual or annualized total return data
generally will be lower than average annual total return data since the average
rates of return reflect compounding of return; aggregate total return data
generally will be higher than average annual total return data since the
aggregate rates of return reflect compounding over a longer period of time.

  In order to reflect the reduced sales charges in the case of Class A or Class
D shares or the waiver of the CDSC in the case of Class B or Class C shares
applicable to certain investors, as described under "Purchase of Shares" and
"Redemption of Shares," respectively, the total return data quoted by the Fund
in advertisements directed to such investors may take into account the reduced,
and not the maximum, sales charge or may take into account the contingent
deferred sales charge and therefore may reflect greater total return since, due
to the reduced sales charge or the waiver of sales charges, a lower amount of
expenses is deducted.     
 
                              GENERAL INFORMATION
 
DESCRIPTION OF SHARES
   
  The Declaration of Trust provides that the Trust shall be comprised of
separate Series each of which will consist of a separate portfolio which will
issue separate shares. The Trust is presently comprised of the Fund, Merrill
Lynch Arizona Municipal Bond Fund, Merrill Lynch Arkansas Municipal Bond Fund,
Merrill Lynch Colorado Municipal Bond Fund, Merrill Lynch Connecticut Municipal
Bond Fund, Merrill Lynch Florida Municipal Bond Fund, Merrill Lynch Maryland
Municipal Bond Fund, Merrill Lynch Massachusetts Municipal Bond Fund, Merrill
Lynch Michigan Municipal Bond Fund, Merrill Lynch Minnesota Municipal Bond
Fund, Merrill Lynch New Mexico Municipal Bond Fund, Merrill Lynch New Jersey
Municipal Bond Fund, Merrill Lynch New York Municipal Bond Fund, Merrill Lynch
North Carolina Municipal Bond Fund, Merrill Lynch Ohio Municipal Bond Fund,
Merrill Lynch Oregon Municipal Bond Fund and Merrill Lynch Texas Municipal Bond
Fund. The Trustees are authorized to create an unlimited number of Series and,
with respect to each Series, to issue an unlimited number of full and
fractional shares of beneficial interest, par value of $.10 per share, of
different classes and to divide or combine the shares into a greater or lesser
number of shares without thereby changing the proportionate beneficial
interests in the Series. Shareholder approval is not necessary for the
authorization of additional Series or classes of a Series of the Trust. At the
date of this Statement of Additional Information, the shares of the Fund are
divided into Class A, Class B, Class C and Class D shares. Class A, Class B,
Class C and Class D shares represent interests in the same assets of the Fund
and are identical in all respects except that the Class B, Class C and Class D
shares bear certain expenses related to the account maintenance and/or
distribution of such shares and have exclusive voting rights with respect to
matters relating to such account maintenance and/or distribution expenditures.
The Trust has received an order (the "Order") from the Commission permitting
the issuance and sale of multiple classes of shares. The Order permits the
Trust to issue additional classes of shares of any Series if the Board of
Trustees deems such issuance to be in the best interest of the Trust. The Board
of Trustees of the Trust may classify and reclassify the shares of any Series
into additional classes at a future date.     
   
  All shares of the Trust have equal voting rights, except that only shares of
the respective Series are entitled to vote on matters concerning only that
Series and, as noted above, Class B, Class C and Class D shares have exclusive
voting rights with respect to matters relating to the account maintenance
and/or distribution expenses being borne solely by such class. Each issued and
outstanding share is entitled to one vote and to participate equally in
dividends and distributions declared by the Fund and in the net assets of such
Series upon liquidation or dissolution remaining after satisfaction of
outstanding liabilities, except that, as noted above, expenses related to the
account maintenance and/or distribution of the Class B, Class C and     
 
                                       51
<PAGE>
 
   
Class D shares are borne solely by such class. There normally will be no
meetings of shareholders for the purposes of electing Trustees unless and until
such time as less than a majority of the Trustees holding office have been
elected by shareholders, at which time the Trustees then in office will call a
shareholders' meeting for the election of Trustees. Shareholders may, in
accordance with the terms of the Declaration of Trust, cause a meeting of
shareholders to be held for the purpose of voting on the removal of Trustees.
Also, the Trust will be required to call a special meeting of shareholders in
accordance with the requirements of the 1940 Act to seek approval of new
management and advisory arrangements, of a material increase in distribution
fees, or of a change in the fundamental policies, objectives or restrictions of
a Series.     
 
  The obligations and liabilities of a particular Series are restricted to the
assets of that Series and do not extend to the assets of the Trust generally.
The shares of each Series, when issued, will be fully paid and nonassessable,
have no preference, preemptive, conversion, exchange or similar rights, and are
freely transferable. Holders of shares of any Series are entitled to redeem
their shares as set forth elsewhere herein and in the Prospectus. Shares do not
have cumulative voting rights and the holders of more than 50% of the shares of
the Trust voting for the election of Trustees can elect all of the Trustees if
they choose to do so and in such event the holders of the remaining shares
would not be able to elect any Trustees. No amendments may be made to the
Declaration of Trust without the affirmative vote of a majority of the
outstanding shares of the Trust.
 
  The Manager provided the initial capital for the Fund by purchasing 10,000
shares of the Fund for $100,000. Such shares were acquired for investment and
can only be disposed of by redemption. The organizational expenses of the Fund
(estimated at approximately $81,100) were paid by the Fund and are amortized
over a period not exceeding five years. The proceeds realized by the Manager
upon the redemption of any of the shares initially purchased by it will be
reduced by the proportionate amount of unamortized organizational expenses
which the number of shares redeemed bears to the number of shares initially
purchased. Such organizational expenses include certain of the initial
organizational expenses of the Trust which have been allocated to the Fund by
the Trustees. If additional Series are added to the Trust, the organizational
expenses will be allocated among the Series in a manner deemed equitable by the
Trustees.

Investment Company Act of 1940, to which reference is hereby made.
 
  The Declaration of Trust establishing the Trust dated August 2, 1985, a copy
of which, together with all amendments thereto (the "Declaration") is on file
in the office of the Secretary of the Commonwealth of Massachusetts, provides
that the name "Merrill Lynch Multi-State Municipal Series Trust" refers to the

                                   APPENDIX I
 
               ECONOMIC AND FINANCIAL CONDITIONS IN PENNSYLVANIA
          
  The following information is a brief summary of factors affecting the economy
of the Commonwealth and does not purport to be a complete description of such
factors. Other factors will affect issuers. The summary is based primarily upon
one or more publicly available offering statements relating to debt offerings
of Commonwealth issuers; however, it has not been updated nor will it be
updated during the year. The Trust has not independently verified the
information.     
   
  Many factors affect the financial condition of the Commonwealth of
Pennsylvania (also referred to as the "Commonwealth") and its political
subdivisions, such as social, environmental and economic conditions, many of
which are not within the control of such entities. Pennsylvania and certain of
its counties, cities and school districts and public bodies have from time to
time in the past encountered financial difficulties which have adversely
affected their respective credit standings. Such difficulties could affect
outstanding obligations of such entities, including obligations held by the
Fund. For example, the financial condition of the City of Philadelphia had
impaired its ability to borrow and resulted in its obligations generally being
downgraded by the major rating services (Moody's, Standard & Poor's and Fitch)
in some cases below investment grade.     
 
  The General Fund, the Commonwealth's largest fund, receives all tax revenues,
non-tax revenues and Federal grants and entitlements that are not specified by
law to be deposited elsewhere. The majority of the Commonwealth's operating and
administrative expenses are payable from the General Fund. Debt service on all
bonded indebtedness of the Commonwealth, except that issued for highway
purposes or for the benefit of other special revenue funds, is payable from the
General Fund.
          
  The five year period from fiscal 1990 through fiscal 1994 was marked by
public health and welfare costs growing at a rate double the growth rate for
all state expenditures. During this period, public health and welfare costs
rose by an average annual rate of 9.4% while tax revenues were growing at an
average annual rate of 5.8%. Consequently, spending on other budget programs
was restrained to a growth rate of 4.7% and sources of revenues other than
taxes (including transfers from other Commonwealth funds and hospital and
nursing home pooling of contributions to use as federal matching funds) became
larger components of fund revenues.     
   
  Fiscal 1995 was the fourth consecutive fiscal year the Commonwealth reported
an increase in the fiscal year-end unappropriated balance. The fiscal 1995
unappropriated surplus (prior to reserves for transfer to the Tax Stabilization
Fund) was $540 million, an increase of $204.2 million over the fiscal 1994
unappropriated surplus (prior to transfers). Commonwealth revenues were
$16,224.6 million, 2.9% above the estimate of revenues used at the time the
budget was enacted. The higher than estimated revenues from tax sources were
due to faster economic growth in the national and state economy than had been
projected when the budget was adopted. Expenditures from Commonwealth revenues
(excluding pooled financing expenditures), including $65.5 million of
supplemental appropriations enacted at the close of the 1995 fiscal year,
totaled $15.67 billion, representing an increase of 5% over spending during
fiscal 1994.     
   
  The enacted fiscal 1996 budget provides for expenditures from Commonwealth
revenues of $16.16 billion, a 2.7% increase over total appropriations from
Commonwealth revenues in fiscal 1995. The fiscal     
 
                                       55
<PAGE>
 
   
1996 budget is based on anticipated Commonwealth revenues, net of enacted tax
changes but prior to tax refunds, of $16.27 billion, an increase over actual
fiscal 1995 Commonwealth revenues of .3%. Excluding the estimated effects of
the tax changes enacted in 1994 and 1995, Commonwealth revenues for fiscal 1996
are estimated to increase by approximately 2.9%. Tax changes (reductions)
enacted with the fiscal 1996 budget totaled $282.9 million, representing an
approximate 1.7% of base revenues. The largest dollar value changes were in the
corporate net income tax where the scheduled 1997 reduction of the tax rate to
9.99% was accelerated to the 1995 tax year; a double weighting was provided for
the sales factor of the corporate net income tax apportionment calculation; and
the maximum allowance for the net operating loss deduction was increased from
$500,000 to $1 million. The fiscal 1996 cost of these corporate net income tax
changes is estimated to be $210.8 million. Other major components of the tax
reduction include a $12.1 million decrease for the capital stock and franchise
tax from an increase in the exemption amount; $24.7 million from the repeal of
the tax on annuities; and $27.9 million from an acceleration of the scheduled
phase-out of the inheritance tax on transfers of certain property to a
surviving spouse. A 90 day amnesty program was also authorized in the tax bill
and will be available to taxpayers from mid-October 1995 through mid-January
1996.     
   
  The economy of Pennsylvania is composed of many diverse sectors including
manufacturing, mining, agriculture, services and wholesale and retail trade.
Certain industries traditionally strong in the Commonwealth, such as coal,
steel and railways, have declined and account for a decreasing share of total
employment. Service industries (including trade, health care, education and
finance) have grown, however, contributing increasingly to Pennsylvania's
economy and now exceed the manufacturing section as the largest single source
of employment.     
   
  Nonagricultural employment in the Commonwealth declined by 5.1% during the
recessionary period from 1980 to 1983. In 1984, the declining trend was
reversed as employment grew by 2.9% over 1983 levels. From 1983 to 1990,
Commonwealth employment continued to grow each year, increasing an additional
14.3%. For the last three years, employment in the Commonwealth has increased
2.0%. The unemployment rate in Pennsylvania in September, 1995 stood at a
seasonally adjusted rate of 6.4%. The seasonally adjusted national unemployment
rate for September, 1995 was 5.6%.     
 
  The current Constitutional provisions pertaining to Commonwealth debt permit
the issuance of the following types of debt: (i) debt to suppress insurrection
or rehabilitate areas affected by disaster, (ii) electorate-approved debt,
(iii) debt for capital projects subject to an aggregate debt limit of 1.75
times the annual average tax revenues of the preceding five fiscal years and
(iv) tax anticipation notes payable in the fiscal year of issuance. All debt
except tax anticipation notes must be amortized in substantial and regular
amounts.
   
  Debt service on all bonded indebtedness of Pennsylvania, except that issued
for highway purposes or the benefit of other special revenue funds, is payable
from Pennsylvania's General Fund, which receives all Commonwealth revenues that
are not specified by law to be deposited elsewhere. As of June 30, 1995, the
Commonwealth had $5.05 million of general obligation debt outstanding.     
 
  Other state-related obligations include "moral obligations". Moral obligation
indebtedness may be issued by the Pennsylvania Housing Finance Agency ("PHFA"),
a state agency which provides financing for housing for lower and moderate
income families, and The Hospitals and Higher Education Facilities
 
                                       56
<PAGE>
 
Authority of Philadelphia, a municipal authority organized by the City of
Philadelphia to, among other things, acquire and prepare various sites for use
as intermediate care facilities for the mentally retarded. PHFA's bonds, but
not its notes, are partially secured by a capital reserve fund required to be
maintained by PHFA in an amount equal to the maximum annual debt service on its
outstanding bonds in any succeeding calendar year. PHFA is not permitted to
borrow additional funds as long as any deficiency exists in the capital reserve
fund.
   
  Certain state-created agencies have statutory authorization to incur debt for
which state appropriations to pay debt service thereon is not required. The
debt of these agencies is supported by assets of, or revenues derived from, the
various projects financed and is not an obligation of the Commonwealth. Some of
these agencies, however, are indirectly dependent on Pennsylvania
appropriations. In addition, the Commonwealth maintains pension plans covering
state employees, public school employees and employees of certain state-related
organizations. For their fiscal years ended in 1994 the State Employees'
Retirement System had a $249 million surplus and the Public School Employees'
Retirement System had a total unfunded actuarial accrued liability of $3.8
billion.     
          
  The City of Philadelphia is the largest city in the Commonwealth with an
estimated population of 1,585,577 according to the 1990 Census. Legislation
providing for the establishment of Pennsylvania Intergovernmental Cooperation
Authority ("PICA") to assist Philadelphia in remedying fiscal emergencies was
enacted by the Pennsylvania General Assembly and approved by the Governor in
June, 1991. PICA is designed to provide assistance through the issuance of
funding debt and to make factual findings and recommendations to Philadelphia
concerning its budgetary and fiscal affairs. At this time, Philadelphia is
operating under a five year fiscal plan approved by PICA on April 17, 1995, as
modified in July 1995.     
          
  To date, PICA has issued $1.42 billion of its Special Tax Revenue Bonds. This
financial assistance has included the refunding of certain general obligation
bonds, funding of capital projects and the liquidation of the cumulative
General Fund balance deficit as of June 30, 1992 of $224.9 million. The audited
General Fund balance of Philadelphia as of June 30, 1994 reflects a surplus of
approximately $15.4 million, up from approximately $3 million as of June 30,
1993. Preliminary unaudited financial statements as of June 30, 1995 project a
surplus approximating $59.6 million.     
   
  There is various litigation pending against the Commonwealth, its officers
and employees. In 1978, the Pennsylvania General Assembly approved a limited
waiver of sovereign immunity. Damages for any loss are limited to $250,000 for
each person and $1 million for each accident. The Supreme Court held that this
limitation is constitutional. Approximately 3,500 suits against the
Commonwealth are pending.     
   
  The following are among the cases with respect to which the Office of
Attorney General and the Office of General Counsel have determined that an
adverse decision may have a material effect on government operations of the
Commonwealth:     
   
Baby Neal v. Commonwealth, et al.     
   
  In 1990, the American Civil Liberties Union and other various named
plaintiffs filed an action against the Commonwealth in Federal court seeking an
order that would require the Commonwealth to provide additional funding for
child welfare services. No figures for the amount of funding sought are
available.     
 
                                       57
<PAGE>
 
   
However, a similar lawsuit filed in the Commonwealth Court of Pennsylvania was
resolved through a court approved settlement which provides, among other
things, for Commonwealth funding for such services in fiscal year 1991 and a
commitment to pay Pennsylvania counties $30 million over five years. In
December 1994, the Third Circuit Court of Appeals reversed the District Court's
denial of the plaintiff's motion for class certification with respect to the
interests of 16 minor plaintiffs. As a result, the District Court has recently
certified the class and the parties have resumed discovery.     
   
County of Allegheny v. Commonwealth of Pennsylvania     
   
  On December 7, 1987, the Supreme Court of Pennsylvania held that the
statutory scheme for county funding of the judicial system is in conflict with
the Pennsylvania Constitution. However, judgment was stayed in order to afford
the General Assembly an opportunity to enact appropriate funding legislation
consistent with its opinion. Since that time, the Supreme Court has denied
various actions and motions by several Pennsylvania municipalities to compel
the Commonwealth to comply with the Supreme Court's 1987 decision or to restore
funding for local courts and district justices to levels existing in 1987. On
December 7, 1992, the State Association of County Commissioners filed a new
action in mandamus seeking to compel the Commonwealth to comply with the
Supreme Court's decision in County of Allegheny. The Commonwealth has filed a
response in opposition to the new action and a request was made by the counties
to continue the action until Spring, 1995. The Court has not apparently acted
on the new action and the General Assembly has yet to consider legislation
implementing the Supreme Court's decision.     
   
Fidelity Bank v. Commonwealth of Pennsylvania     
   
  On November 30, 1989, Fidelity Bank, N.A. ("Fidelity") filed an action in
challenging the constitutional validity of a 1989 amendment increasing the bank
shares tax and related legislation. The Commonwealth Court ruled in favor of
the Commonwealth finding no constitutional deficiencies in the tax increase,
but invalidating one element of the legislation which provided a credit to new
banks (the "new bank tax credit"). Fidelity, the Commonwealth and certain
intervener banks appealed to the Pennsylvania Supreme Court. However, pursuant
to a Settlement Agreement dated as of April 21, 1995, the Commonwealth agreed
to enter a credit in favor of Fidelity in the amount of $4,100,000 in
settlement of the constitutional and non-constitutional issues. The credit
represents approximately 5% of the potential claim of Fidelity, had the
constitutional issues been resolved in its favor.     
   
  Pursuant to a separate Settlement Agreement dated as of April 21, 1995, the
Commonwealth also settled with the intervening banks with respect to issues
concerning the new bank tax credit.     
   
  Notwithstanding the foregoing settlements, other banks have filed protective
petitions which are currently pending at the various administrative agencies
challenging the validity of the 1989 tax increase. At least one of those cases
- -- Mellon Bank, N.A. -- has progressed to Commonwealth Court. Based upon the
favorable decision of the Commonwealth Court on the constitutional issues in
the Fidelity Bank litigation and the terms of the settlement with Fidelity, the
Commonwealth does not expect that substantial liability remains with respect to
the remaining cases.     
   
Pennsylvania Association of Rural and Small Schools (PARSS) v. Casey     
   
  In January 1991, the Association of Rural and Small Schools and several other
parties filed a lawsuit against then Governor Robert P. Casey and former
Secretary of Education, Donald M. Carroll challenging     
 
                                       58
<PAGE>
 
   
the constitutionality of the Commonwealth system for funding local school
districts. The litigation consists of two parallel cases, one in the
Commonwealth Court of Pennsylvania and one in the United States District Court
for the Middle District of Pennsylvania. The federal court case has been
indefinitely stayed pending resolution of the state court case. The state court
case is currently in the pre-trial discovery stage.     
   
Austin v. Department of Corrections, et al.     
   
  In November 1990, the American Civil Liberties Union filed a class action
lawsuit in the United States District Court for the Eastern District of
Pennsylvania on behalf of inmate populations in various Pennsylvania
correctional institutions, challenging the conditions of confinement and
seeking injunctive relief. On January 17, 1995, the Court approved a Settlement
Agreement between the parties, pursuant to which the Commonwealth paid $1.3
million in attorney's fees to the plaintiffs' attorneys, with an additional
$100,000 to be paid upon dismissal of a preliminary injunction relating to
certain health issues. The parties are presently complying with monitoring
provisions outlined in the Settlement Agreement.     
   
Scott v. Snider     
   
  In 1991, a consortium of public interest law firms filed a class action suit
in the U.S. District Court for the Eastern District of Pennsylvania against
various Commonwealth officers alleging that the Commonwealth had failed to
comply with the 1989 federal mandate to provide and pay for early and periodic
screening, diagnostic and treatment services for Medicaid-eligible children. If
the federal court were to grant all of the relief requested, the Commonwealth
would be obligated, among other things, to substantially revise the methods by
which it presently identifies children in need of treatment and to expand the
scope of services and treatment presently provided to such children, and to
increase fees paid to pediatric providers. The Court had denied the plaintiffs'
request to proceed as a class action and dismissed five of the eighteen
plaintiff organizations from the case. On June 2, 1995, the Court approved the
settlement reached by the parties.     
   
Envirotest/Synterra Partners     
   
  Envirotest Systems Corporation, Envirotest Partners ("Envirotest") and the
Commonwealth of Pennsylvania have entered into a Standstill Agreement pursuant
to which the parties will proceed to discuss resolution of claims which
Envirotest might have against the Commonwealth arising from the suspension of
an emissions testing program. Under the program, Envirotest entered into a
contract with the Commonwealth for the operation of emissions inspection
facilities and, incident thereto, acquired land to construct approximately 85
such facilities. On May 10, 1995, Envirotest filed a Statement of Claim with
the Pennsylvania Board of Claims, and filed a complaint with the Commonwealth
Court on May 15, 1995, to preserve its position. In these pleadings, Envirotest
alleges damages in excess of $350 million. The Office of General Counsel has
been informed by representatives of Envirotest that it has expended
approximately $200 million to date to acquire land and construct and maintain
the inspection facilities.     
   
  Currently, Pennsylvania general obligation bonds are rated AA-- by Standard &
Poor's and Fitch, and A1 by Moody's. There can be no assurance that the
economic conditions on which these ratings are based will continue or that
particular bond issues will not be adversely affected by changes in economic or
political conditions.

                           RATINGS OF MUNICIPAL BONDS
 
DESCRIPTION OF MOODY'S INVESTORS SERVICE, INC.'S ("MOODY'S") MUNICIPAL BOND
RATINGS
 
Aaa  Bonds which are rated Aaa are judged to be of the best quality. They
     carry the smallest degree of investment risk and are generally
     referred to as "gilt edge". Interest payments are protected by a large
     or by an exceptionally stable margin and principal is secure. While
     the various protective elements are likely to change, such changes as
     can be visualized are most unlikely to impair the fundamentally strong
     position of such issues.
 
Aa   Bonds which are rated Aa are judged to be of high quality by all
     standards. Together with the Aaa group they comprise what are
     generally known as high grade bonds. They are rated lower than the
     best bonds because margins of protection may not be as large as in Aaa
     securities or fluctuation of protective elements may be of greater
     amplitude or there may be other elements present which make the long-
     term risks appear somewhat larger 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 a susceptibility to impairment
     sometime in the future.
 
Baa  Bonds which are rated Baa are considered as medium grade obligations;
     i.e., they are neither highly protected nor poorly secured. Interest
     payment 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.
 
Ba   Bonds which are rated Ba are judged to have speculative elements;
     their future cannot be considered as well assured. Often the
     protection of interest and principal payments may be very moderate and
     thereby not well safeguarded during both good and bad times over the
     future. Uncertainty of position characterizes bonds in this class.
 
B    Bonds which are rated B generally lack characteristics of the
     desirable investment. Assurance of interest and principal payment or
     of maintenance of other terms of the contract over any long period of
     time may be small.
 
Caa  Bonds which are rated Caa are of poor standing. Such issues may be in
     default or there may be present elements of danger with respect to
     principal or interest.
 
     Bonds which are rated Ca represent obligations which are speculative
Ca   in a high degree. Such issues are often in default or have other
     marked shortcomings.
 
C    Bonds which are rated C are the lowest rated class of bonds and issues
     so rated can be regarded as having extremely poor prospects of ever
     attaining any real investment standing.
 
  Note: Those bonds in the Aa, A, Baa, Ba and B groups which Moody's believes
possess the strongest investment attributes are designated by the symbols Aa1,
A1, Baa1, Ba1 and B1.

  Short-term Notes: The four ratings of Moody's for short-term notes are MIG
1/VMIG1, MIG 2/VMIG2, MIG 3/VMIG3 and MIG 4/VMIG4; MIG 1/VMIG1 denotes "best
quality . . . strong protection by established cash flows"; MIG 2/VMIG2 denotes
"high quality" with ample margins of protection; MIG 3/VMIG3 notes are of
"favorable quality . . . but . . . lacking the undeniable strength of the
preceding grades"; MIG 4/VMIG4 notes are of "adequate quality . . .
[p]rotection commonly regarded as required of an investment security is
present . . . there is specific risk."
 
DESCRIPTION OF MOODY'S CORPORATE BOND RATINGS
 
  Excerpts from Moody's description of its corporate bond ratings: Aaa--judged
to be the best quality, carry the smallest degree of investment risk; Aa--
judged to be of high quality by all standards; A--possess many favorable
investment attributes and are to be considered as upper medium grade
obligations; Baa--considered as medium grade obligations, i.e., they are
neither highly protected nor poorly secured.
 
DESCRIPTION OF MOODY'S COMMERCIAL PAPER RATINGS
 
  Moody's Commercial Paper ratings are opinions of the ability of issuers to
repay punctually promissory obligations not having an original maturity in
excess of nine months. Moody's employs the following three designations, all
judged to be investment grade, to indicate the relative repayment capacity of
rated issuers:
 
  Issuers rated Prime-1 (or related supporting institutions) have a superior
capacity for repayment of short-term promissory obligations. Prime-1 repayment
capacity will normally be evidenced by the following characteristics: leading
market positions in well established industries; high rates of return on funds
employed; conservative capitalization structures with moderate reliance on debt
and ample asset protection; broad margins in earnings coverage of fixed
financial charges and high internal cash generation; and well established
access to a range of financial markets and assured sources of alternate
liquidity.
 
  Issuers rated Prime-2 (or related supporting institutions) have a strong
capacity for repayment of short-term promissory obligations. This will normally
be evidenced by many of the characteristics cited above but to a lesser degree.
Earnings trends and coverage ratios, while sound, will be more subject to
variation. Capitalization characteristics, while still appropriate, may be more
affected by external conditions. Ample alternate liquidity is maintained.
 
  Issuers rated Prime-3 (or related supporting institutions) have an acceptable
capacity for repayment of short-term promissory obligations. The effects of
industry characteristics and market composition may be more pronounced.
Variability in earnings and profitability may result in changes in the level of
debt protection measurements and the requirement for relatively high financial
leverage. Adequate alternate liquidity is maintained.
 
  Issuers rated Not Prime do not fall within any of the Prime rating
categories.
   
DESCRIPTION OF STANDARD & POOR'S RATINGS GROUP ("STANDARD & POOR'S") MUNICIPAL
DEBT RATINGS     
 
  A Standard & Poor's municipal debt rating is a current assessment of the
creditworthiness of an obligor with respect to a specific obligation. This
assessment may take into consideration obligors such as guarantors, insurers,
or lessees.
 
                                       61
<PAGE>
 
  The debt rating is not a recommendation to purchase, sell or hold a security,
inasmuch as it does not comment as to market price or suitability for a
particular investor.
 
  The ratings are based on current information furnished by the issuer or
obtained by Standard & Poor's from other sources Standard & Poor's considers
reliable. Standard & Poor's does not perform any audit in connection with any
rating and may, on occasion, rely on unaudited financial information. The
ratings may be changed, suspended or withdrawn as a result of changes in, or
unavailability of, such information, or for other circumstances.
 
  The ratings are based, in varying degrees, on the following considerations:
 
    I. Likelihood of default--capacity and willingness of the obligor as to
  the timely payment of interest and repayment of principal in accordance
  with the terms of the obligation;
 
    II. Nature of and provisions of the obligation;
 
    III. Protection afforded to, and relative position of, the obligation in
  the event of bankruptcy, reorganization or other arrangement under the laws
  of bankruptcy and other laws affecting creditor's rights.
 
AAA  Debt rate "AAA" has the highest rating assigned by Standard & Poor's.
     Capacity to pay interest and repay principal is extremely strong.
 
AA   Debt rated "AA" has a very strong capacity to pay interest and repay
     principal and differs from the higher rated issues only in small
     degree.
 
A    Debt rated "A" has a strong capacity to pay interest and repay
     principal although it is somewhat more susceptible to the adverse
     effects of changes in circumstances and economic conditions than debt
     in higher rated categories.
 
BBB  Debt rated "BBB" is regarded as having an adequate capacity to pay
     interest and repay principal. Whereas it normally exhibits adequate
     protection parameters, adverse economic conditions or changing
     circumstances are more likely to lead to a weakened capacity to pay
     interest and repay principal for debt in this category than for debt
     in higher rated categories.
 
BB B CCC CC C
     Debt rated "BB", "B", "CCC" and "CC" is regarded, on balance, as
     predominantly speculative with respect to capacity to pay interest and
     repay principal in accordance with the terms of the obligations. "BB"
     indicates the lowest degree of speculation and "C" the highest degree
     of speculation. While such debt will likely have some quality and
     protective characteristics, these are outweighed by large
     uncertainties or major risk exposures to adverse conditions.
 
CI   The rating "C" is reserved for income bonds on which no interest is
     being paid.
 
D    Debt rated "D" is in payment default. The "D" rating category is used
     when interest payments or principal payments are not made on the date
     due even if the applicable grace period has not expired, unless
     Standard & Poor's believes that such payments will be made during such
     grace period. The "D" rating also will be used upon the filing of a
     bankruptcy petition if debt service payments are jeopardized.
 
                                       62
<PAGE>
 
  Plus (+) or Minus (-): The ratings from "AA" to "CCC" may be modified by the
addition of a plus or minus sign to show relative standing within the major
rating categories.
 
DESCRIPTION OF STANDARD & POOR'S CORPORATE BOND RATINGS
 
  A Standard & Poor's corporate debt rating is a current assessment of the
creditworthiness of an obligor with respect to a specific obligation. Debt
rated "AAA" has the highest rating assigned by Standard & Poor's. Capacity to
pay interest and repay principal is extremely strong. Debt rated "AA" has a
very strong capacity to pay interest and to repay principal and differs from
the highest rated issues only in small degree. Debt rated "A" has a strong
capacity to pay interest and repay principal although it is somewhat more
susceptible to the adverse effects of changes in circumstances and economic
conditions than a debt of a higher rated category. Debt rated "BBB" is regarded
as having an adequate capacity to pay interest and repay principal. Whereas it
normally exhibits adequate protection parameters, adverse economic conditions
or changing circumstances are more likely to lead to a weakened capacity to pay
interest and repay principal for debt in this category than for debt in higher
rated categories.
 
  The ratings from "AA" to "BBB" may be modified by the addition of a plus or
minus sign to show relative standing within the major rating categories.
 
DESCRIPTION OF STANDARD & POOR'S COMMERCIAL PAPER RATINGS
 
  A Standard & Poor's Commercial Paper Rating is a current assessment of the
likelihood of timely payment of debt having an original maturity of no more
than 365 days. Ratings are graded into several categories, ranging from "A-1"
for the highest quality obligations to "D" for the lowest. These categories are
as follows:
 
  A-1 This highest category indicates that the degree of safety regarding timely
      payment is strong. Those issues determined to possess extremely strong
      safety characteristics are denoted with a plus sign (+) designation.
 
  A-2 Capacity for timely payment on issues with this designation is
      satisfactory. However, the relative degree of safety is not as high as
      for issues designated "A-1".
 
  A-3 Issues carrying this designation have adequate capacity for timely
      payment. They are, however, somewhat more vulnerable to the adverse
      effects of changes in circumstances than obligations carrying the
      higher designations.
 
  B   Issues rated "B" are regarded as having only speculative capacity for
      timely payment.
 
  C   This rating is assigned to short-term debt obligations with a doubtful
      capacity for payment.
 
  D   Debt rated "D" is in payment default. The "D" rating category is used when
      interest payments or principal payments are not made on the date due, even
      if the applicable grace period has not expired, unless Standard & Poor's
      believes that such payments will be made during such grace period.
 
  A Commercial Paper Rating is not a recommendation to purchase or sell a
security. The ratings are based on current information furnished to Standard &
Poor's by the issuer or obtained by Standard & Poor's
 
                                       63
<PAGE>
 
from other sources it considers reliable. The ratings may be changed,
suspended, or withdrawn as a result of changes in, or unavailability of, such
information.
 
  A Standard & Poor's note rating reflects the liquidity concerns and market
access risks unique to notes. Notes due in 3 years or less will likely receive
a note rating. Notes maturing beyond 3 years will most likely receive a long-
term debt rating. The following criteria will be used in making that
assessment.
 
  --Amortization schedule (the larger the final maturity relative to other
   maturities, the more likely it will be treated as a note).
 
  --Source of payment (the more dependent the issue is on the market for its
   refinancing, the more likely it will be treated as a note).
 
  Note rating symbols are as follows:
 
SP-1 A very strong, or strong, capacity to pay principal and interest. Issues
     that possess overwhelming safety characteristics will be given a "+"
     designation.
 
SP-2 A satisfactory capacity to pay principal and interest.
 
SP-3 A speculative capacity to pay principal and interest.
 
  Unrated: Where no rating has been assigned or where a rating has been
suspended or withdrawn, it may be for reasons unrelated to the quality of the
issue.
 
  Should no rating be assigned, the reason may be one of the following:
 
  1. An application for rating was not received or accepted.
 
  2. The issue or issuers belongs to a group of securities that is not rated as
     a matter of policy.
 
  3. There is a lack of essential data pertaining to the issue or issuer.
   
  4. The issue was privately placed, in which case the rating is not published
in Standard & Poor's publications.     
 
  Suspension or withdrawal may occur if new and material circumstances arise,
the effects of which preclude satisfactory analysis; if there is no longer
available reasonable up-to-date information to permit a judgment to be formed;
if a bond is called for redemption; or for other reasons.
 
DESCRIPTION OF FITCH INVESTORS SERVICE, INC.'S ("FITCH") INVESTMENT GRADE BOND
RATINGS
 
  Fitch investment grade bond ratings provide a guide to investors in
determining the credit risk associated with a particular security. The ratings
represent Fitch's assessment of the issuer's ability to meet the obligations of
a specific debt issue or class of debt in a timely manner.
 
  The rating takes into consideration special features of the issue, its
relationship to other obligations of the issuer, the current and prospective
financial condition and operative performance of the issuer and any guarantor,
as well as the political and economic environment that might affect the
issuer's future financial strength and credit quality.
 
                                       64
<PAGE>
 
  Fitch ratings do not reflect any credit enhancement that may be provided by
insurance policies or financial guaranties unless otherwise indicated.
 
  Bonds that have the same rating are of similar but not necessarily identical
credit quality since the rating categories do not fully reflect small
differences in the degrees of credit risk.
 
  Fitch ratings are not recommendations to buy, sell, or hold any security.
Ratings do not comment on the adequacy of market price, the suitability of any
security for a particular investor, or the tax-exempt nature or taxability of
payments made in respect of any security.
 
  Fitch ratings are based on information obtained from issuers, other obligors,
underwriters, their experts, and other sources Fitch believes to be reliable.
Fitch does not audit or verify the truth or accuracy of such information.
Ratings may be changed, suspended, or withdrawn as a result of changes in, or
the unavailability of, information or for other reasons.
 
AAA     Bonds considered to be investment grade and of the highest credit
        quality. The obligor has an exceptionally strong ability to pay
        interest and repay principal, which is unlikely to be affected by
        reasonably forseeable events.
 
AA      Bonds considered to be investment grade and of very high quality. The
        obligor's ability to pay interest and repay principal is very strong,
        although not quite as strong as bonds rated "AAA". Because bonds rated
        in the "AAA" and "AA" categories are not significantly vulnerable to
        foreseeable future developments, short-term debt of these issuers is
        generally rated "F-1+".
 
A       Bonds considered to be investment grade and of high credit quality. The
        obligor's ability to pay interest and repay principal is considered to
        be strong, but may be more vulnerable to adverse changes in economic
        conditions and circumstances than bonds with higher ratings.
 
BBB     Bonds considered to be investment grade and of satisfactory credit
        quality. The obligor's ability to pay interest and repay principal is
        considered to be adequate. Adverse changes in economic conditions and
        circumstances, however, are more likely to have adverse impact on these
        bonds, and therefore, impair timely payment. The likelihood that the
        ratings of these bonds will fall below investment grade is higher than
        for bonds with higher ratings.
 
  Plus (+) or Minus (-): Plus and minus signs are used with a rating symbol to
indicate the relative position of a credit within the rating category. Plus and
minus signs, however, are not used in the "AAA" category.
 
  Credit Trend Indicator: Credit trend indicators show whether credit
fundamentals are improving, stable, declining, or uncertain, as follows:
 
  Improving     (UP ARROW)
 
  Stable        (LEFT ARROW/RIGHT ARROW)
 
  Declining     (DOWN ARROW)
 
  Uncertain     (UP/DOWN ARROW)
 
                                       65
<PAGE>
 
  Credit trend indicators are not predictions that any rating change will
occur, and have a longer-term time frame than issues placed on FitchAlert.
 
NR:         Indicates that Fitch does not rate the specific issue.
 
Conditional:A conditional rating is premised on the successful completion of a
            project or the occurrence of a specific event.
 
Suspended:  A rating is suspended when Fitch deems the amount of information
            available from the issuer to be inadequate for rating purposes.
 
Withdrawn:  A rating will be withdrawn when an issue matures or is called or
            refinanced and, at Fitch's discretion, when an issuer fails to
            furnish proper and timely information.
 
FitchAlert: Ratings are placed on FitchAlert to notify investors of the
            occurrence that is likely to result in a rating change and the
            likely direction of such change. These are designated as
            "Positive" indicating a potential upgrade, "Negative" for
            potential downgrade, or "Evolving" where ratings may be raised or
            lowered. FitchAlert is relatively short-term, and should be
            resolved within 12 months.
 
DESCRIPTION OF FITCH SPECULATIVE GRADE BOND RATINGS
 
  Fitch speculative grade bond ratings provide a guide to investors in
determining the credit risk associated with a security. The ratings ("BB" to
"C") represent Fitch's assessment of the likelihood of timely payment of
principal and interest in accordance with the terms of obligation for bond
issues not in default. For defaulted bonds, the rating ("DDD" to "D") is an
assessment of the ultimate recovery value through reorganization or
liquidation.
 
  The rating takes into consideration special features of the issue, the
relationship to other obligations of the issuer, the current and prospective
financial condition and operating performance of the issuer and any guarantor,
as well as the economic and political environment that might affect the
issuer's future financial strength.
 
  Bonds that have the same rating are of similar but not necessarily identical
credit quality since rating categories cannot fully reflect the differences in
degrees of credit risk.
 
BB              Bonds are considered speculative. The obligor's ability to pay
                interest and repay principal may be affected over time by
                adverse economic changes. However, business and financial
                alternatives can be identified which could assist the obligor
                in satisfying its debt service requirements.
 
B               Bonds are considered highly speculative. While bonds in this
                class are currently meeting debt service requirements, the
                probability of continued timely payment of principal and
                interest reflects the obligor's limited margin of safety and
                the need for reasonable business and economic activity
                throughout the life of the issue.
 
CCC             Bonds have certain identifiable characteristics which, if not
                remedied, may lead to default. The ability to meet obligations
                requires an advantageous business and economic environment.
 
                                       66
<PAGE>
 
CC              Bonds are minimally protected. Default in payment of interest
                and/or principal seems probable over time.
 
C               Bonds are in imminent default in payment of interest or
                principal.
 
DDD, DD, and    Bonds are in default of interest and/or principal payments.
D               Such bonds are extremely speculative and should be valued on
                the basis of their ultimate recovery value in liquidation or
                reorganization of the obligor. "DDD" represents the highest
                potential for recovery on these bonds, and "D" represents the
                lowest potential for recovery.
 
  Plus (+) Minus (-): Plus and minus signs are used with a rating symbol to
indicate the relative position of a credit within the rating category. Plus and
minus signs, however, are not used in the "DDD", "DD", or "D" categories.
 
DESCRIPTION OF FITCH INVESTMENT GRADE SHORT-TERM RATINGS
 
  Fitch short-term ratings apply to debt obligations that are payable on demand
or have original maturities of generally up to three years, including
commercial paper, certificates of deposit, medium-term notes, and municipal and
investment notes.
 
  The short-term rating places greater emphasis than a long-term rating on the
existence of liquidity necessary to meet the issuer's obligations in a timely
manner.
 
  Fitch short-term ratings are as follows:
 
F-1+        Exceptionally Strong Credit Quality. Issues assigned this rating
            are regarded as having the strongest degree of assurance for
            timely payment.
 
F-1         Very Strong Credit Quality. Issues assigned this rating reflect an
            assurance of timely payment only slightly less in degree than
            issues rated "F-1+".
 
F-2         Good Credit Quality. Issues assigned this rating have a
            satisfactory degree of assurance for timely payment, but the
            margin of safety is not as great as the "F-1+" and "F-1" ratings.
 
F-3         Fair Credit Quality. Issues assigned this rating have
            characteristics suggesting that the degree of assurance for timely
            payment is adequate, however, near-term adverse changes could
            cause these securities to be rated below investment grade.
 
F-S         Weak Credit Quality. Issues assigned this rating have
            characteristics suggesting a minimal degree of assurance for
            timely payment and are vulnerable to near-term adverse changes in
            financial and economic conditions.
 
D           Default. Issues carrying this rating are in actual or imminent
            payment default.
 
LOC         The symbol, LOC, indicates that the rating is based on a letter of
            credit issued by a commercial bank.
            
INS         The symbol "INS" indicates that the rating is based on an
            insurance policy or financial guaranty issued by an insurance
            company.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and the financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned at July
31, 1995 by correspondence with the custodian. An audit also includes assessing
the accounting principles used and significant estimates made by management, as
well as evaluating the overall financial statement presentation. We believe
that our audits provide a reasonable basis for our opinion.     
   
In our opinion, such financial statements and financial highlights present
fairly, in all material respects, the financial position of Merrill Lynch
Pennsylvania Municipal Bond Fund of Merrill Lynch Multi-State Municipal Series
Trust as of July 31, 1995, the results of its operations, the changes in its
net assets, and the financial highlights for the respective stated periods in
conformity with generally accepted accounting principles.

NOTES TO FINANCIAL STATEMENTS

1. Significant Accounting Policies:
Merrill Lynch Pennsylvania Municipal Bond Fund (the "Fund") is part
of Merrill Lynch Multi-State Municipal Series Trust (the "Trust").
The Fund is registered under the Investment Company Act of 1940 as a
non-diversified, open-end management investment company. The Fund
offers four classes of shares under the Merrill Lynch Select
Pricing SM System. Shares of Class A and Class D are sold with a
front-end sales charge. Shares of Class B and Class C may be subject
to a contingent deferred sales charge. All classes of shares have
identical voting, dividend, liquidation and other rights and the
same terms and conditions, except that Class B, Class C and Class D
Shares bear certain expenses related to the account maintenance of
such shares, and Class B and Class C Shares also bear certain
expenses related to the distribution of such shares. Each class has
exclusive voting rights with respect to matters relating to its
account maintenance and distribution expenditures. The following is
a summary of significant accounting policies followed by the Fund.

(a) Valuation of investments--Municipal bonds and other portfolio
securities in which the Fund invests are traded primarily in the
over-the-counter municipal bond and money markets and are valued at
the last available bid price in the over-the-counter market or on
the basis of yield equivalents as obtained from one or more dealers
that make markets in the securities. Financial futures contracts and
options thereon, which are traded on exchanges, are valued at their
settlement prices as of the close of such exchanges. Short-term
investments with remaining maturities of sixty days or less are
valued at amortized cost, which approximates market value.
Securities and assets for which market quotations are not readily
available are valued at fair value as determined in good faith by or
under the direction of the Board of Trustees of the Trust, including
valuations furnished by a pricing service retained by the Trust,
which may utilize a matrix system for valuations. The procedures of
the pricing service and its valuations are reviewed by the officers
of the Trust under the general supervision of the Trustees.

(b) Derivative financial instruments--The Fund may engage in various
portfolio strategies to seek to increase its return by hedging its
portfolio against adverse movements in the debt markets. Losses may
arise due to changes in the value of the contract or if the
counterparty does not perform under the contract.

* Financial futures contracts--The Fund may purchase or sell interest
rate futures contacts and options on such futures contracts for the
purpose of hedging the market risk on existing securities or the
intended purchase of securities. Futures contracts are contracts for
delayed delivery of securities at a specific future date and at a
specific price or yield. Upon entering into a contract, the Fund
deposits and maintains as collateral such initial margin as required
by the exchange on which the transaction is effected. Pursuant to
the contract, the Fund agrees to receive from or pay to the broker
an amount of cash equal to the daily fluctuation in value of the
contract. Such receipts or payments are known as variation margin
and are recorded by the Fund as unrealized gains or losses. When the
contract is closed, the Fund records a realized gain or loss equal
to the difference between the value of the contract at the time it
was opened and the value at the time it was closed.

(c) Income 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 substantially all of its
taxable income to its shareholders. Therefore, no Federal income tax
provision is required.

(d) Security transactions and investment income--Security
transactions are recorded on the dates the transactions are entered
into (the trade dates). Interest income is recognized on the accrual
basis. Discounts and market premiums are amortized into interest
income. Realized gains and losses on security transactions are
determined on the identified cost basis.

(e) Deferred organization expenses and prepaid registration fees--
Deferred organization expenses are charged to expense on a straight-
line basis over a five-year period. Prepaid registration fees are
charged to expense as the related shares are issued.

(f) Dividends and distributions--Dividends from net investment
income are declared daily and paid monthly. Distributions of capital
gains are recorded 

                                      79
<PAGE>
 
on the ex-dividend dates. Distributions in excess of realized capital gains are
due primarily to differing tax treatments for futures transactions and post-
October losses.

2. Investment Advisory Agreement and 
Transactions with Affiliates:
The Fund has entered into an Investment Advisory Agreement with Fund
Asset Management, L.P. ("FAM"). The general partner of FAM is
Princeton Services, Inc. ("PSI"), an indirect wholly-owned
subsidiary of Merrill Lynch & Co., Inc. ("ML & Co."), which is the
limited partner. The Fund has also entered into a Distribution
Agreement and Distribution Plans with Merrill Lynch Funds
Distributor, Inc. ("MLFD" or "Distributor"), a wholly-owned
subsidiary of Merrill Lynch Group, Inc.

FAM is responsible for the management of the Fund's portfolio and
provides the necessary personnel, facilities, equipment and certain
other services necessary to the operations of the Fund. For such
services, the Fund pays a monthly fee based upon the average daily
value of the Fund's net assets at the following annual rates: 0.55%
of the Fund's average daily net assets not exceeding $500 million;
0.525% of average daily net assets in excess of $500 million but not
exceeding $1 billion; and 0.50% of average daily net assets in
excess of $1 billion. The Investment Advisory Agreement obligates
FAM to reimburse the Fund to the extent the Fund's expenses
(excluding interest, taxes, distribution fees, brokerage fees and
commissions, and extraordinary items) exceed 2.5% of the Fund's
first $30 million of average daily net assets, 2.0% of the next $70
million of average daily net assets, and 1.5% of the average daily
net assets in excess thereof. FAM's obligation to reimburse the Fund
is limited to the amount of the management fee. No fee payment will
be made to the Investment Adviser during any fiscal year which will
cause such expenses to exceed expense limitation at the time of
payment.

Pursuant to the distribution plans ("the Distribution Plans")
adopted by the Fund in accordance with Rule 12b-1 under the
Investment Company Act of 1940, the Fund pays the Distributor
ongoing account maintenance and distribution fees. The fees are
accrued daily and paid monthly at annual rates based upon the
average daily net assets of the shares as follows:



                                          Account     Distribution
                                      Maintenance Fee      Fee

Class B                                     0.25%          0.25%
Class C                                     0.25%          0.35%
Class D                                     0.10%           --



Pursuant to a sub-agreement with the Distributor, Merrill Lynch,
Pierce, Fenner & Smith Inc. ("MLPF&S"), a subsidiary of ML & Co.,
also provides account maintenance and distribution services to the
Fund. The ongoing account maintenance fee compensates the
Distributor and MLPF&S for providing account maintenance services to
Class B, Class C and Class D shareholders. The ongoing distribution
fee compensates the Distributor and MLPF&S for providing shareholder
and distribution-related services to Class B and Class C
shareholders.

For the year ended July 31, 1995, MLFD earned underwriting discounts
and MLPF&S earned dealer concessions on sales of the Fund's Class A
and Class D Shares as follows:



                                        MLFD         MLPF&S

Class A                                $1,289        $14,788
Class D                                   702         25,153



For the year ended July 31, 1995, MLPF&S received contingent
deferred sales charges of $302,369 and $621 relating to transactions
in Class B and Class C Shares, respectively.

Merrill Lynch Financial Data Services, Inc. ("MLFDS"), a wholly-
owned subsidiary of ML & Co., is the Fund's transfer agent.

Accounting services are provided to the Fund by FAM at cost.

Certain officers and/or trustees of the Fund are officers and/or
directors of FAM, PSI, MLPF&S, MLFDS, MLFD, and/or ML & Co.

3. Investments:
Purchases and sales of investments, excluding short-term securities,
for the year ended July 31, 1995 were $83,480,248 and $85,623,359,
respectively.

ITEM 27. INDEMNIFICATION.
 
  Section 5.3 of the Registrant's Declaration of Trust provides as follows:
 
  "The Trust shall indemnify each of its Trustees, officers, employees and
agents (including persons who serve at its request as directors, officers or
trustees of another organization in which it has any interest as a shareholder,
creditor or otherwise) against all liabilities and expenses (including amounts
paid in satisfaction of judgments, in compromise, as fines and penalties and as
counsel fees) reasonably incurred by him in connection with the defense or
disposition of any action, suit or other proceeding, whether civil or criminal,
in which he may be involved or with which he may be threatened, while in office
or thereafter, by reason of his being or having been such a trustee, officer,
employee or agent, except with respect to any matter as to which he shall have
been adjudicated to have acted in bad faith, willful misfeasance, gross
negligence or reckless disregard of his duties; provided, however, that as to
any matter disposed of by a compromise payment by such person, pursuant to a
consent decree or otherwise, no indemnification either for said payment or for
any other expenses shall be provided unless the Trust shall have received a
written opinion from independent legal counsel approved by the Trustees to the
effect that if either the matter of willful misfeasance, gross negligence or
reckless disregard of duty, or the matter of good faith and reasonable belief
as to the best interests of the Trust, had been adjudicated, it would have been
adjudicated in favor of such person. The rights accruing to any Person under
these provisions shall not exclude any other right to which he may be lawfully
entitled; provided that no person may satisfy any right in indemnity or
reimbursement granted herein or in Section 5.1 or to which he may be otherwise
entitled except out of the property of the Trust, and no Shareholder shall be
personally liable to any Person with respect to any claim for indemnity or
reimbursement or otherwise. The Trustees may make advance payments in
connection with indemnification under this Section 5.3, provided that the
indemnified person shall have given a written undertaking to reimburse the
Trust in the event it is subsequently determined that he is not entitled to
such indemnification."
 
  Insofar as the conditional advancing of indemnification monies for actions
based upon the Investment Company Act of 1940, as amended, may be concerned,
such payments will be made only on the following conditions: (i) the advances
must be limited to amounts used, or to be used, for the preparation or
presentation of a defense to the action, including costs connected with the
preparation of a settlement; (ii) advances may be made only upon receipt of a
written promise by, or on behalf of, the recipient to repay that amount of the
advance which exceeds the amount to which it is ultimately determined that he
is entitled to receive from the Registrant by reason of indemnification; and
(iii)(a) such promise must be secured by a surety bond, other suitable
insurance or an equivalent form of security which assures that any repayments
may be obtained by the Registrant without delay or litigation, which bond,
insurance or other form of security must be provided by the recipient of the
advance, or (b) a majority of a quorum of the Registrant's disinterested, non-
party
 
                                      C-3
<PAGE>
 
Trustees, or an independent legal counsel in a written opinion, shall
determine, based upon a review of readily available facts that the recipient of
the advance ultimately will be found entitled to indemnification.
 
  In Section 9 of the Distribution Agreements relating to the securities being
offered hereby, the Registrant agrees to indemnify the Distributor and each
person, if any, who controls the Distributor within the meaning of the
Securities Act of 1933, as amended (the "1933 Act"), against certain types of
civil liabilities arising in connection with the Registration Statement or
Prospectus and Statement of Additional Information.
 
  Insofar as indemnification for liabilities arising under the 1933 Act may be
permitted to Trustees, officers and controlling persons of the Registrant and
the principal underwriter 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 1933 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 Trustee officer, or controlling
person of the Registrant and the principal underwriter in connection with the
successful defense of any action, suit or proceeding) is asserted by such
Director, officer or controlling person or the principal underwriter in
connection with the shares being registered, the Registrant will, unless in the
opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the 1933 Act and
will be governed by the final adjudication of such issue.

time in question have been duly elected or appointed as trustees in accordance
with the provisions of this Declaration of Trust and are then in office, being
hereinafter called the "Trustees").

Series as the context may require.

        "Trustees" shall mean the signatories to this Declaration of Trust, so 
         --------
long as they shall continue in office in accordance with the terms hereof, and
all other persons who at the time in question have been duly elected or
appointed and have qualified as trustees in accordance with the provisions
hereof and are then in office, are herein referred to as the "Trustees", and
reference in this Declaration of Trust to a Trustee or Trustees shall refer to

extent permitted by the 1940 Act, be filled by the appointment of an individual
having the qualifications described in this Article 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 individual 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 this Declaration of Trust. No
reduction in the number of Trustees shall have the effect of removing any
Trustee from office prior to the expiration of his term. Whenever a vacancy in
the number of Trustees shall occur, until such vacancy is filled as provided in
Section 2.3 hereof, 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 this Declaration of Trust. A Trustee shall be an
individual at least 21 years of age who is not under legal disability. Trustees
need not own Shares.

        2.2.  Term of Office.  The Trustees shall hold office during the 
              --------------
lifetime of this Trust, and until its termination as hereinafter provided;
except (a) that any Trustee may resign his trust by written instrument signed by
him and delivered to the other Trustees, which shall take effect upon such
delivery or upon such later date as is specified therein; (b) that any trustee
may be removed at any time by written instrument, signed by at least two-thirds
of the number of Trustees prior to such removal, specifying the date when such
removal shall become effective; (c) that any Trustee who requests in writing to
be retired or, who had become incapacitated by illness or injury may be retired
by written instrument signed by a majority of the other Trustees, specifying the
date of his retirement; and (d) a Trustee may be removed at any special meeting
of the shareholders by a vote of two-thirds of the outstanding Shares. 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 conveying to the Trust or the remaining Trustees any
Trust Property held in the name of the resigning or removed Trustee. Upon the
incapacity or death of any Trustee, his legal representative shall execute and
deliver on his behalf such documents as the remaining Trustees shall require as
provided in the preceding sentence.

        2.3.  Vacancies.  The term of office of a Trustee shall terminate and a
              ---------
vacancy shall occur in the event of the death, resignation, bankruptcy,
adjudicated incompetence or other incapacity to perform the duties of the
office, or removal, of a Trustee.  No such vacancy shall operate to annul this
Declaration of Trust or to revoke any existing agency created pursuant to the

Declaration.

        2.4.  Meetings.  Meetings of the Trustees shall be held from time to

time upon the call of the Chairman, if any, the President, the Secretary or any
two Trustees. Regular meetings of the Trustees may be held without call or
notice at a time and place fixed by the By-Laws or by resolution of the
Trustees. Notice of any other meeting shall be mailed or otherwise given not
less than 48 hours before the meeting but may be waived in writing by any
Trustee either before or after such meeting. The attendance of a Trustee at a
meeting shall constitute a waiver of notice of such meeting except where a
Trustee attends a meeting for the express purpose of objecting to the
transaction of any business on the ground that the meeting has not been
lawfully called or convened. The Trustees may act with or without a meeting. A
quorum for all meetings of the Trustees shall be a majority of the Trustees.
Unless provided otherwise in this Declaration of Trust, any action of the
Trustees may be taken at a meeting by vote of a majority of the Trustees present
(a quorum being present) or without a meeting by written consents of a majority
of the Trustees.

        Any committee of the Trustees, including an executive committee, if any,
may act with or without a meeting.  A quorum for all meetings of any such

a meeting by vote of a majority of the members present (a quorum being present)
or without a meeting by written consent of a majority of the members.

Trustees, Trustees who are Interested Persons of the Trust within the meaning of
Section 1.2 hereof or otherwise interested in any action to be taken may be
counted for quorum purposes under this Section and shall be entitled to vote to
the extent permitted by the 1940 Act.

        To the extent permitted by the 1940 Act, all or any one or more Trustees
may participate in a meeting of the Trustees or any committee thereof by means
of a conference telephone or similar communications equipment by means of which
all persons participating in the meeting can hear each other and participation
in a meeting pursuant to such communications systems shall constitute presence
in person at such meeting.

        2.5.  Officers.  The Trustees shall annually elect a President, a 
              --------
Secretary and a Treasurer and may elect a Chairman. The Trustees may elect or
appoint or authorize the Chairman, if any, or President to appoint such other
officers or agents with such powers as the Trustees may deem to be advisable.
The Chairman and President shall be and the Secretary and Treasurer may, but
need not, be a Trustee.

              -------
over the Trust Property and over the business of the Trust or any Series thereof

permitted by this Declaration. The Trustees may perform such acts as in their
sole discretion are proper for conducting the business of the Trust or any
Series thereof. The enumeration of any specific power herein shall not be

corporation or other business entity organized under the laws of the United
States and, to the extent provided in the Prospectus and not prohibited by the

any additional securities in which any Series of the Trust may invest should the
investment policies set forth in the Prospectus or the Fundamental Policies be
amended.

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

one or more of the Trustees, or in the name of the Trust or any Series thereof,
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 or any Series thereof therein
is appropriately protected.

        The right, title and interest of the Trustees in the Trust Property
shall vest automatically in each Person who may hereafter become a Trustee upon
his due election and qualification. Upon the resignation, removal or death of a
Trustee he shall automatically cease to have any right, title or interest in any

and cessation of title shall be effective whether or not conveyancing documents
have been executed and delivered.

              -------------------------------------
the power to issue, sell, repurchase, redeem, retire, cancel, acquire, hold,

shares in fractional denominations, and, subject to the more detailed provisions
set forth in Articles VIII and IX, to apply to any such repurchase, redemption,
retirement, cancellation or acquisition of Shares any funds or property of the
applicable Series 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.

        3.5.  Borrow Money.  Subject to the Fundamental Policies, the Trustees
              ------------
shall have power to borrow money or otherwise obtain credit and to secure the
same by mortgaging, pledging or otherwise subjecting as security the assets of
the Trust or any Series thereof, including the lending of portfolio securities,
and to endorse, guarantee, or undertake the performance of any obligation,
contract or engagement of any other person, firm, association or corporation.

        3.6.  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 the names of
the Trustees or otherwise as the Trustees may deem expedient, to the same
extent as such delegation is permitted to directors of a Massachusetts business
corporation and is permitted by the 1940 Act.  

        3.7.  Collection and Payment.  The Trustees shall have power to 
              ----------------------
collect all property due to the Trust or any Series thereof; to pay all claims,

other instrument.

              --------
expenses which in the opinion of the Trustees are necessary or incidental to
carry out any of the purposes of this Declaration of Trust, 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.  The Trustees may pay themselves such compensation for special
services, including legal, underwriting, syndicating and brokerage services, as
they in good faith may deem reasonable and reimbursement for expenses
reasonably incurred by themselves on behalf of the Trust.

        3.9.  Miscellaneous Powers.  The Trustees shall have the power to:  (a)
              --------------------
employ or contract with such Persons as the Trustees may deem desirable for the
transaction of the business of the Trust or any Series thereof; (b) enter into
joint ventures, partnerships and any other combinations or associations; (c)
purchase, and pay for out of Trust Property, insurance policies insuring the
Shareholders, Trustees, officers, employees, agents, investment advisors,
distributors, selected dealers or independent contractors of the Trust or any

capacity, whether or not constituting negligence, or whether or not the Trust
would have the power to indemnify such Person against such liability; (d)
establish pension, profit-sharing, share purchase, and other retirement,
incentive and benefit plans for any Trustees, officers, employees and agents of
the Trust; (e) make donations, irrespective of benefit to the Trust, for

obligations of others; (h) determine and change the fiscal year of the Trust
and the method in which its accounts shall be kept; and (i) adopt a seal for

America, in the District of Columbia, and in any and all commonwealths,
territories, dependencies, colonies, possessions, agencies or instrumentalities
of the United States of America and of foreign governments, and to do all such
other things and execute all such instruments as they deem necessary, proper or
desirable in order to promote the interests of the Trust or any Series thereof
although such things are not herein specifically mentioned. Any determination as
to what is in the interests of the Trust or any Series thereof made by the
Trustees in good faith shall be conclusive. In construing the provisions of this
Declaration, the presumption shall be in favor of a grant of power to the
Trustees. The Trustees will not be required to obtain any court order to deal
with the Trust Property.

              ------------------------------------
Shareholder Vote of the applicable Series, as required by the 1940 Act, the
Trustees may in their discretion from time to time enter into advisory or
management contracts whereby the other party to such contract shall undertake
to furnish the Trustees such advisory and management services, with respect to
a Series as the Trustees shall from time to time consider desirable and all
upon such terms and conditions as the Trustees may in their discretion
determine.  Notwithstanding any provisions of this Declaration of Trust, the
Trustees may authorize any advisor or manager (subject to such general or
specific instructions as the Trustees may from time to time adopt) to effect
purchases, sales, loans or exchanges of portfolio securities of any Series of
the Trust on behalf of the Trustees or may authorize any officer, employee or
Trustee to effect such purchases, sales, loans or exchanges pursuant to

        4.2.  Distribution Arrangements.  The Trustees may in their discretion 
              -------------------------
from time to time enter into a contract, providing for the sale of the Shares of
the Trust or any Series of the Trust to net the Trust not less than the par
value per share, whereby the Trust may either agree to sell the Shares to the
other party to the contract or appoint such other party its sales agent for such
Shares. In either case, the contract shall be on such terms and conditions as
the Trustees may in their discretion determine not inconsistent with the
provisions of this Article IV or the By-Laws; and such contract may also provide
for the repurchase or sale of Shares by such other party as principal or as
agent of the Trust and may provide that such other party may enter into selected
dealer agreements with registered securities dealers to further the purpose of
the distribution or repurchase of the Shares.

into with any corporation, firm, trust or association, although one or more of
the Trustees or officers of the Trust may be an officer, director, Trustee,
shareholder, or member of such other party to the contract, and no such
contract shall be invalidated or rendered voidable by reason of the existence
of any such relationship, nor shall any person holding such relationship be
liable merely by reason of such relationship for any loss or expense to the
Trust under or by reason of said contract or accountable for any profit
realized directly or indirectly therefrom, provided that the contract when
entered into was reasonable and fair and not inconsistent with the provisions
of this Article IV or the By-Laws.  The same person (including a firm,
corporation, trust, or association) may be the other party to contracts entered
into pursuant to Sections 4.1 and 4.2 above or Article VII, and any individual
may be financially interested or

Sections 4.1 and 4.2 of this Article IV shall be consistent with and subject to
the requirements of Section 15 of the 1940 Act with respect to its continuance
in effect, its termination, and the method of authorization and approval of
such contract or renewal thereof, and no amendment to any contract entered into
pursuant to Section 4.1 shall be effective unless assented to by a Majority
Shareholder Vote of the applicable Series.

                   Limitations of Liability of Shareholders,
                              Trustees and Others
                   -----------------------------------------

        5.1.  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
shall be subject to any personal liability whatsoever to any Person, other than
the Trust or its Shareholders, in connection with Trust Property or the affairs
of the Trust or any Series thereof, save only that arising from his bad faith,
willful misfeasance, gross negligence or reckless disregard of his duty to such
Person; and all such Persons shall look solely to the Trust Property for
satisfaction of claims of any nature arising in connection with the affairs of
the Trust or any Series thereof. If any Shareholder, Trustee, officer, employee,
or agent, as such, of the Trust, is made a party to any suit or proceeding to
enforce any such liability, 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 for all legal and other expenses reasonably incurred
by him in connection with any such claim or liability. The rights accruing to a
Shareholder under this Section 5.1 shall not exclude any other right to which
such Shareholder may be lawfully entitled, nor shall anything herein contained
restrict the right of the Trust to indemnify or reimburse a Shareholder in any
appropriate situation even though not specifically provided herein.

        5.2.  Non-Liability of Trustees, etc.  No Trustee, officer, employee or
              ------------------------------
agent of the Trust shall be liable to the Trust, any Series, 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 his duties.

        5.3.  Mandatory Indemnification.  The Trust shall indemnify each of its
              -------------------------
Trustees, officers, employees, and agents (including persons who serve at its
request as directors, officers or trustees of another organization in which it
has any interest, as a shareholder, creditor or otherwise) against all
liabilities and expenses (including amounts paid in satisfaction of judgments,
in compromise, as fines and penalties, and as counsel fees) reasonably incurred
by him in connection with the defense or disposition of any action, suit or
other proceeding, whether civil or criminal, in which he may be involved or
with which he may be threatened, while in office or thereafter, by reason of
his being or having been such a trustee, officer, employee or agent, except
with respect to any matter as to which he shall have been adjudicated to have
acted in bad faith, willful misfeasance, gross negligence or reckless disregard
of his duties; provided, however, that as to any matter disposed of by a
compromise 

                                      12.
<PAGE>
 
payment by such person, pursuant to a consent decree or otherwise, no
indemnification either for said payment or for any other expenses shall be
provided unless the Trust shall have received a written opinion from independent
legal counsel approved by the Trustees to the effect that if either the matter
of willful misfeasance, gross negligence or reckless disregard of duty, or the
matter of good faith and reasonable belief as to the best interests of the
Trust, had been adjudicated, it would have been adjudicated in favor of such
person. The rights accruing to any Person under these provisions shall not
exclude any other right to which he may be lawfully entitled; provided that no
Person may satisfy any right of indemnity or reimbursement granted herein or in
Section 5.1 or to which he may be otherwise entitled except out of the property
of the Trust, and no Shareholder shall be personally liable to any Person with
respect to any claim for indemnity or reimbursement or otherwise. The Trustees
may make advance payments in connection with indemnification under this Section
5.3, provided that the indemnified person shall have given a written undertaking
to reimburse the Trust in the event it is subsequently determined that he is not
entitled to such indemnification.

        5.4.  No Bond Required of Trustees.  No Trustee shall, as such, be
              ----------------------------
obligated to give any bond or security or other security for the performance of
any of his duties hereunder.

        5.5.  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 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,
undertaking, instrument, certificate, Share, other security of the Trust or any
Series, and every other act or thing whatsoever executed in connection with the
Trust or any Series shall be conclusively taken to have been executed or done
by the executors thereof only in their capacity as Trustees under this
Declaration of Trust or in their capacity as officers, employees or agents of
the Trust.  Every written obligation, contract, undertaking, instrument,
certificate, Share, other security of the Trust or any Series made or issued by
the Trustees or by any officers, employees or agents of the Trust, in their
capacity as such, shall contain an appropriate recital to the effect that the
Shareholders, Trustees, officers, employees and agents of the Trust shall not
personally be bound by or liable thereunder, nor shall resort be had to their
private property for the satisfaction of any obligation or claim thereunder,
and appropriate references shall be made therein to the Declaration of Trust,
and may contain any further recital which they may deem appropriate, but the
omission of such recital shall not operate to impose personal liability on any
of the Trustees, Shareholders, officers, employees or agents of the Trust.  The
Trustees may maintain insurance for the protection of the Trust Property, 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.

        5.6.  Reliance on Experts, etc.  Each Trustee and officer or employee of
              -------------------------
the Trust 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, upon an opinion of counsel, or upon reports made to the Trust by any of
its officers or employees or by any advisor, administrator, manager,
distributor, selected dealer, accountant, appraiser or other expert or
consultant 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.

                         Shares of Beneficial Interest
                         -----------------------------

        6.1.  Beneficial Interest.  The interest of the beneficiaries hereunder
              -------------------
shall be divided into transferable shares of beneficial interest with par value
$.10 per share.  The number of such shares of beneficial interest authorized
hereunder is unlimited.  All Shares issued hereunder including, without
limitation, Shares issued in connection with a dividend in Shares or a split of
Shares, shall be fully paid and nonassessable.

        6.2.  Series Designation.  The Trustees, in their discretion from time 
              ------------------
to time, may authorize the division of Shares into two or more Series, each
Series relating to a separate portfolio of investments. The different Series
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; provided, that all Shares shall be identical except that there
may be variations between different Series as to purchase price, determination
of net asset value, the price, terms and manner of redemption, special and
relative rights as to dividends and on liquidation, conversion rights, and
conditions under which the several Series shall have separate voting rights. All
references to Shares in this Declaration shall be deemed to be shares of any or
all Series as the context may require.

        If the Trustees shall divide the Shares into two or more Series, the
following provisions shall be applicable:

        (a)     The number of Shares of each Series 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 into one or more Series
that may be established and designated from time to time.  The Trustees may
hold as treasury Shares (of the same or some other Series), reissue for such
consideration and on such terms as they may determine, or cancel any Shares of
any Series reacquired by the Trust at their discretion from time to time.

        (b)  The power of the Trustees to invest and reinvest the Trust 
Property of each Series that may be established shall be governed by Section 3.2
of this Declaration.

        (c)  All consideration received by the Trust for the issue or sale of 
Shares of a particular Series, 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
investment 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,
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

                                      15.
<PAGE>
 
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.

        (d)  The assets belonging to each particular Series shall be charged 
with the liabilities of the Trust in respect of that Series only and all
expenses, costs, charges and reserves attributable to that Series and shall not
be charged with the liabilities, expenses, costs, charges and reserves
attributable to other Series, 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 holders of all
Series for all purposes. The Trustees shall have full discretion, to the extent
not inconsistent with the 1940 Act, to determine which items shall be treated as
income and which items as capital; and each such determination and allocation
shall be conclusive and binding upon the Shareholders.

        (e)  The power of the Trustees to pay dividends and make distributions 
with respect to any one or more Series shall be governed by Section 9.2 of this
Trust. Dividends and distributions on Shares of a particular Series may be paid
with such frequency as the Trustees may determine, to the holders of Shares of
that Series, 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. All
dividends and distributions on Shares of a particular Series shall be
distributed pro rata to the holders of that Series in proportion to the number
of Shares of that Series held by such holders at the date and time of record
established for the payment of such dividends or distributions.

        The establishment and designation of any Series of Shares shall be
effective upon the execution by a majority of the then Trustees of an
instrument setting forth the establishment and designation of such Series. 
Such instrument shall also set forth any rights and preferences of such Series
which are in addition to the rights and preferences of Shares set forth in this
Declaration.  At any time that there are no Shares outstanding of any
particular Series previously established and designated, the Trustees may by an
instrument executed by a majority of their number abolish that Series and the
establishment and designation thereof.  Each instrument referred to in this
paragraph shall have the status of an amendment to this Declaration.

        6.3.  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
with respect to a particular Series, and they shall have no right to call for
any 

                                      16.
<PAGE>
 
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 in this Declaration
specifically set forth. The Shares shall not entitle the holder to preference,
preemptive, appraisal, conversion or exchange rights (except for rights of
appraisal specified in Section 11.4).

        6.4.  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.

        6.5.  Issuance of Shares.  The Trustees, in their discretion, may from 
              ------------------
time to time without vote of the Shareholders issue Shares with respect to any
Series that may have been established pursuant to Section 6.2, in addition to
the then issued and outstanding Shares and Shares held in the treasury, to such
party or parties and for such amount not less than par value and type of
consideration, including cash or property, at such time or times (including,
without limitation, each business day in accordance with the maintenance of a
constant net asset value per share as set forth in Section 9.3 hereof), and on
such terms as the Trustees may deem best, 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. The Trustees may from time
to time divide or combine the Shares of any Series into a greater or lesser
number without thereby changing the proportionate beneficial interests in such
Series of the Trust. Reductions in the number of outstanding Shares may be made
pursuant to the constant net asset value per share formula set forth in Section
9.3. Contributions to the Trust may be accepted for, and Shares shall be
redeemed as, whole Shares and/or 1/1,000ths of a Share or multiples thereof.

        6.6.  Register of Shares.  A register shall be kept at the Trust or any
              ------------------
transfer agent duly appointed by the Trustees under the direction of the
Trustees which shall contain the names and addresses of the Shareholders and
the number of Shares (with respect to each Series that may have been
established) held by them respectively and a record of all transfers thereof. 
Separate registers shall be established and maintained for each Series of the
Trust.  Each such register shall be conclusive as to who are the holders of the
Shares of the applicable Series 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 herein provided, until he has
given his address to a transfer agent or such other officer or agent of the
Trustees as shall keep the register for entry thereon. It is not contemplated
that certificates will be issued for the Shares; however, the Trustees, in
their discretion, may au-

                                      17.
<PAGE>
 
thorize the issuance of share certificates and promulgate appropriate rules and
regulations as to their use.

        6.7.  Transfer Agent and Registrar.  The Trustee shall have power to 
              ----------------------------
employ a transfer agent or transfer agents, and a registrar or registrars, with
respect to the Shares of the various Series. The transfer agent or transfer
agents may keep the applicable register and record therein the original issues
and transfers, if any, of the said Shares of the applicable Series. Any such
transfer agent and registrars shall perform the duties usually performed by
transfer agents and registrars of certificates of stock in a corporation, except
as modified by the Trustees.

        6.8.  Transfer of Shares.  Shares shall be transferable on the records 
              ------------------
of the Trust only by the record holder thereof or by his agent thereto duly
authorized in writing, upon delivery to the Trustees or a transfer agent of the
Trust 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 applicable 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
hereof 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 applicable register of Shares as the holder of
such Shares upon production of the proper evidence thereof to the Trustees or a
transfer agent of the Trust, but until such record is made, the Shareholder of
record shall be deemed to be the holder of such Shares for all purposes hereof
and neither the Trustees nor any transfer agent or registrar nor any officer or
agent of the Trust shall be affected by any notice of such death, bankruptcy or
incompetence, or other operation of law.

        6.9.  Notices.  Any and all notices to which any Shareholder hereunder 
              -------
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 applicable register of the Trust.

                                  Custodians
                                  ----------

        7.1   Appointment and Duties.  The Trustees shall at all times employ 
              ----------------------
a custodian or custodians, meeting the qualifications for custodians for
portfolio securities of investment companies contained in the 1940 Act, as
custodian with respect to each Series of the Trust. It is contemplated that
separate custodians may be employed for the different Series of the Trust. Any
custodian, acting with respect to one or more Series, shall have authority as
agent of the Trust or the Series with respect to which it is acting, but subject
to such restrictions, limitations and other requirements, if any, as may be
contained in the By-Laws of the Trust and the 1940 Act:

                (1)  to hold the securities owned by the Trust or the Series 
        and deliver the same upon written order;

                (2)  to receive and receipt for any moneys due to the Trust or 
        the Series and deposit the same in its own banking department (if a
        bank) or elsewhere as the Trustees may direct;

                (3)  to disburse such funds upon orders or vouchers;

                (4) if authorized by the Trustees, to keep the books and
        accounts of the Trust or the Series and furnish clerical and accounting
        services; and

                (5) if authorized to do so by the Trustees, to compute the net
        income of the Trust or the Series,

all upon such basis of compensation as may be agreed upon between the
Trustees and the custodian.  If so directed by a Majority Shareholder vote of
the Series with respect to which the custodian is acting, the custodian shall
deliver and pay over all property of the Trust held by it as specified in such
vote.

        The Trustees may also authorize each custodian to employ one or more
subcustodians from time to time to perform such of the acts and services of the
custodian and upon such terms and conditions, as may be agreed upon between the
custodian and such sub-custodian and approved by the Trustees, provided that in
every case such sub-custodian shall meet the qualifications for custodians
contained in the 1940 Act.

        7.2.  Central Certificate System.  Subject to such rules, 
              -------------------------- 
regulations and order as the Commission may adopt, the Trustees may direct the
custodian to deposit all or any part of the securities owned by the Trust or the
Series in a system for the central handling of securities established by a
national securities exchange or a national securities association registered
with the Commission under the Securities Exchange Act of 1934, or such other
person as may be permitted by the Commission, or otherwise in accordance with
the 1940

Act, pursuant to which system all securities of any particular class or
series or any issuer deposited within the system are treated as fungible and may
be transferred or pledged by bookkeeping entry without physical delivery of such
securities, provided that all such deposits shall be subject to withdrawal only
upon the order of the Trust.

                                  Redemption
                                  ----------

        8.1.  Redemptions.  All outstanding Shares of any Series of the Trust 
              -----------
may be redeemed at the option of the holders thereof, upon and subject to the
terms and conditions provided in this Article VIII. The Trust shall, upon
application of any Shareholder or pursuant to authorization from any Shareholder
of a particular Series, redeem or repurchase from such Shareholder outstanding
Shares of such Series for an amount per share determined by the application of a
formula adopted for such purpose by the Trustees with respect to such Series
(which formula shall be consistent with the 1940 Act); provided that (a) such
amount per share shall not exceed the cash equivalent of the proportionate
interest of each share in the assets of the Series of the Trust at the time of
the purchase or redemption and (b) if so authorized by the Trustees, the Trust
may, at any time and from time to time, charge fees for effecting such
redemption, at such rates as the Trustees may establish, as and to the extent
permitted under the 1940 Act, and may, at any time and from time to time,
pursuant to such Act, suspend such right of redemption. The procedures for
effecting redemption shall be as set forth in the Prospectus with respect to the
applicable Series from time to time.

        8.2.  Redemption of Shares; Disclosure of Holding.  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 as a
regulated investment company under the Internal Revenue Code, then the Trustees
shall have the power by lot or other means deemed equitable by them (i) to call
for redemption a number, or principal amount, of Shares or other securities of
the Trust sufficient, in the opinion of the Trustees, to maintain or bring the
direct or indirect ownership of Shares or other securities 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 to any Person whose
acquisition of the Shares or other securities of the Trust in question would in
the opinion of the Trustees result in such disqualification. The redemption
shall be effected at a redemption price determined in accordance with Section
8.1.

        The holders of Shares or other securities 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 as the Trustees
deem necessary to comply with the provisions of the Internal Revenue Code, or
to comply with the requirements of any other taxing authority.

        8.3.  Redemptions of Accounts of Less than $1,000.  Due to the 
              -------------------------------------------
relatively high cost of maintaining investment accounts of less than $1,000, the
Trustees shall have the power to redeem shares at a redemption price determined
in accordance with Section 8.1 if at any time the total investment in such
account does not have a value of at least $1,000; provided, however, that the
Trustees 

                                      21.
<PAGE>
 
may not exercise such power with respect to Shares of any Series if the
Prospectus of such Series does not describe such power. In the event the
Trustees determine to exercise their power to redeem Shares provided in this
Section 8.3, shareholders shall be notified that the value of their account is
less than $1,000 and allowed 60 days to make an additional investment before
redemption is processed.

        8.4.  Redemptions Pursuant to Constant Net Asset Value Formula.  The 
              --------------------------------------------------------
Trust may also reduce the number of outstanding Shares of any Series pursuant to
the provisions of Section 9.3.

                       ---------------------------------

        9.1.  Net Asset Value.  The net asset value of each outstanding Share 
              ---------------
of each Series of the Trust shall be determined at such time or times on such
days as the Trustees may determine, in accordance with the 1940 Act, with
respect to each Series. The method of determination of net asset value shall be
determined by the Trustees and shall be as set forth in the Prospectus with
respect to the applicable Series. The power and duty to make the daily
calculations for any Series may be delegated by the Trustees to the adviser,
administrator, manager, custodian, transfer agent or such other person as the
Trustees may determine. The Trustees may suspend the daily determination of net
asset value to the extent permitted by the 1940 Act.

        9.2.  Distributions to Shareholders.  The Trustees shall from time 
              ----------------------------- 
to time distribute ratably among the Shareholders of any Series such proportion
of the net profits, surplus (including paid-in surplus), capital, or assets with
respect to such Series held by the Trustees as they may deem proper. Such
distribution may be made in cash or property (including without limitation any
type of obligations of the Trust or any assets thereof), and the Trustees may
distribute ratably among the Shareholders of any Series additional Shares of
such Series in such manner, at such times, and on such terms as the Trustees may
deem proper. Such distributions may be among the Shareholders of record at the
time of declaring a distribution or among the Shareholders of record at such
later date as the Trustees shall determine. 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 to meet obligations of the Trust, 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 of any Series such dividend reinvestment plans, cash dividend
payout plans or related plans as the Trustees shall deem appropriate for such
Series.

        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 to avoid or reduce liability for taxes.

        9.3.  Constant Net Asset Value; Reduction of Outstanding Shares.  The
              ---------------------------------------------------------
Trustees shall have the power to determine the net income of any Series of the
Trust on each day the net asset value of such Series is determined as provided
in Section 9.1 and at each such determination declare such net income for such
Series as dividends with the result that the net asset value per share of the
Series of the Trust shall remain at a constant dollar value.  The determination
of net income end the resultant declaration of dividends shall be as set forth
in the Prospectus.  In such event fluctuations in value may be reflected in the

                                      23.
<PAGE>
 
number of outstanding Shares in each Shareholder's account.  It is expected
that each Series of the Trust will have a positive net income at the time of
each determination.  If for any reason such net income is a negative amount,
the Trust may offset such amount against dividends accrued in the account of
the Shareholder of the applicable Series.  If and to the extent such negative
amount exceeds such accrued dividends, the Trust shall have authority to reduce
the number of the outstanding Shares of the Series. Such reduction will be
effected by having each Shareholder proportionately contributing to the Series
capital the necessary Shares that represent the amount of the excess upon such
determination.  Each Shareholder will be deemed to have agreed to such
contribution in these circumstances by his investment in the Series of the
trust.  This procedure will permit the net asset value per share of the Series
of the Trust to be maintained at a constant dollar value per share.

        The Trustees, by resolution, may discontinue or amend the practice of
maintaining the net asset value per share at a constant dollar amount with 
respect to any Series at any time and such modification shall be evidenced by
appropriate changes in the Prospectus.  

        9.4.  Power to Modify Foregoing Procedures.  Notwithstanding any of the
              ------------------------------------
foregoing provisions of this Article IX, the Trustees may prescribe, in
absolute discretion, such other bases and times for determining the per share
net asset value of the Trust's Shares or net income, or the declaration and
payment of dividends and distributions as they may deem necessary or desirable
to enable the Trust to comply with any provision of the 1940 Act, or any
securities association registered under the Securities Exchange Act of 1934, or
any order of exemption issued by said Commission, all as in effect now or
hereafter amended or modified.

        10.1.  Voting Powers.  The Shareholders shall have power to vote (i) 
               --------------
for the removal of Trustees as provided in Section 2.2; (ii) with respect to any
advisory or management contract of a Series as provided in Section 4.1; (iii)
with respect to the amendment of this Declaration as provided in Section 11.3;
and (iv) with respect to such additional matters relating to the Trust as may be
required or authorized by the 1940 Act or other applicable law or by this
Declaration or by the By-Laws of the Trust.

        10.2.  Meetings of Shareholders.  Special meetings of the Shareholders 
               ------------------------
may be called at any time by a majority of the Trustees and shall be called by
any Trustee upon written request of Shareholders of any Series holding in the
aggregate not less than 10% of the outstanding Shares of such Series having
voting rights, such request specifying the purpose or purposes for which such
meeting is to be called. Any such meeting shall be held within or without the
Commonwealth of Massachusetts on such day and at such time as the Trustees shall
designate. The holders of one-third of outstanding Shares of each Series present
in person or by proxy shall constitute a quorum for the transaction of any
business, except as may otherwise be required by the 1940 Act or other
applicable law or by this Declaration or the By-Laws of the Trust. If a quorum
is present at a meeting of a particular Series, the affirmative vote of a
majority of the Shares of such Series represented at the meeting constitutes the
action of the Shareholders, unless the 1940 Act, other applicable law, this
Declaration or the By-Laws of the Trust requires a greater number of affirmative
votes.

        10.3.  Notice of Meetings.  Notice of all meetings of the Shareholders,
               ------------------
stating the time, place and purposes of the meeting, shall be given by the
Trustees by mail to each Shareholder at his registered address, mailed st least
10 days and not more than 60 days before the meeting. Only the business stated
in the notice of the meeting shall be considered at such meeting. Any adjourned
meeting may be held as adjourned without further notice.

        10.4.  Record Date for Meetings.  For the purpose of determining the 
               ------------------------
Shareholders who are entitled to notice of and to vote at any meeting, or to
participate in any distribution, or for the purpose of any other action, the
Trustees may from time to time close the transfer books for such period, not
exceeding 30 days, as the Trustees may determine; or without closing the
transfer books the Trustees may fix a date not more than 60 days prior to the
date of any meeting of Shareholders or daily dividends or other action as a
record date for the determination of the Persons to be treated as Shareholders
of record for such purposes, except for dividend payments which shall be
governed by Section 9.2 hereof.

        10.5.  Proxies, etc.  At any meeting of Shareholders, any holder of 
               ------------
Shares entitled to vote thereat may vote by proxy, provided that no proxy shall

retary, or with such other officer or agent of the Trust as the Secretary may
direct, for verification prior to the time at which such vote shall be taken.
Pursuant to a resolution of a majority of the Trustees, proxies may be solicited
in the name of one or more Trustees or one or more of the officers of the Trust.
Only Shareholders of record shall be entitled to vote. Each full Share shall be
entitled to one vote and fractional Shares shall be entitled to a vote of such
fraction. When any Share is held jointly by several persons, any one of them may
vote at any meeting in person or by proxy ln respect of such Share, but if more
than one of them shall be present at such meeting in person or by proxy, and
such joint owners or their proxies so present disagree as to any vote to be
cast, such vote shall not be received in respect of such Share. A proxy
purporting to be executed by or on behalf of a Shareholder shall be deemed valid
unless challenged at or prior to its exercise, and the burden of proving
invalidity shall rest on the challenger. If the holder of any such Share is a
minor or a person of unsound mind, and subject to guardianship or to the legal
control of any other person as regards the charge or management of such Share,
he may vote by his guardian or such other person appointed or having such
control, and such vote may be given in person or by proxy.

        10.6.  Reports.  The Trustees shall cause to be prepared with respect 
               -------
to each Series at least annually a report of operations containing a balance
sheet and statement of income and undistributed income of the applicable Series
of the Trust prepared in conformity with generally accepted accounting
principles and an opinion of an independent public accountant on such financial
statements. It is contemplated that separate reports may be prepared for the
various Series. Copies of such reports shall be mailed to all Shareholders of
record of the applicable Series within the time required by the 1940 Act, and in
any event within a reasonable period preceding the annual meeting of
Shareholders. The Trustees shall, in addition, furnish to the Shareholders at
least annually, interim reports containing an unaudited balance sheet of the
Series as of the end of such period and an unaudited statement of income and
surplus for the period from the beginning of the current fiscal year to the end
of such period.

        10.7.  Inspection of Records.  The records of the Trust shall be open 
               ---------------------
to inspection by Shareholders to the same extent as is permitted shareholders of
a Massachusetts business corporation.

        10.8.  Shareholder Action by Written Consent.  Any action which may be 
               -------------------------------------
taken by Shareholders may be taken without a meeting if a majority of
Shareholders of each Series entitled to vote on the matter (or such larger
proportion thereof as shall be required by any express provision of this
Declaration) consent to the action in writing and the written consents are filed
with the records of the meetings of Shareholders. Such consent shall he treated
for all purposes as a vote taken at a meeting of Shareholders.

        11.2.  Termination.

        (a)  The Trust may be terminated by the affirmative vote of the 
holders of not less than two-thirds of the Shares of each Series of the Trust at
any meeting of Shareholders or by an instrument in writing, without a meeting,
signed by a majority of the Trustees and consented to by the holders of not less
than two-thirds of such Shares. Any Series may be so terminated by vote or
written consent of not less than two-thirds of the Shares of such Series. Upon
the termination of the Trust or any Series,

                (i)  The Trust or such Series 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 or such Series and all of the powers of the Trustees under this
        Declaration shall continue until the affairs of the Trust or such Series
        shall have been wound up, including the power to fulfill or discharge
        the 

                                      27.
<PAGE>
 
        contracts of the Trust or such Series, collect its assets, sell,
        convey, assign, exchange, transfer or otherwise dispose of all or any
        part of the remaining Trust Property 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 shall require approval of the principal terms of the
        transaction and the nature and amount of the consideration by vote or
        consent of the holders of a majority of the Shares entitled to vote.

                (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 of any Series, in
        cash or in kind or partly each, among the Shareholders of such Series
        according to their respective rights.

        (b)  After termination of the Trust or any Series and distribution to 
the Shareholders as herein provided, a majority of the Trustees shall execute

the fact of such termination. Upon termination of the Trust, the Trustees shall
thereupon be discharged from all further liabilities and duties hereunder, and
the rights and interests of all Shareholders shall thereupon cease. Upon
termination of any Series, the Trustees shall thereunder be discharged from all
further liabilities and duties with respect to such Series, and the rights and
interests of all Shareholders of such Series shall thereupon cease.

        11.3.  Amendment Procedure.
               ------------------- 

        (a)  This Declaration may be amended by the affirmative vote of the 
holders of not less than a majority of the Shares at any meeting of Shareholders
or by an instrument in writing, without a meeting, signed by a majority of the
Trustees and consented to by the holders of not less than a majority of such
Shares. The Shareholders of each Series shall have the right to vote separately
on amendments to this Declaration to the extent provided by Section 10.1. The
Trustees may also 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 laws or regulations or the requirements of
the regulated investment company provisions of the Internal Revenue Code, but
the Trustees shall not be liable for failing so to do.

        (b)  No amendment may be made, under Section 11.3(a) above, which would
change any rights with respect to any Shares of the Trust by reducing the
amount payable thereon upon liquidation of the Trust 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 each Series.  Nothing
contained in this Declaration shall permit the amendment of this Declaration to
impair the 

                                      28.
<PAGE>
 
exemption from personal liability of the Shareholders, Trustees, officers,
employees and agents of the Trust or to permit assessments upon Shareholders.

        (c)  A certification in recordable form 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, in recordable form, and executed by a majority of the Trustees, shall
be conclusive evidence of such amendment when lodged among the records of the
trust.

        Notwithstanding any other provision hereof, until such time as a
Registration Statement under the Securities Act of 1933, as amended, covering
the first public offering of Shares of the Trust shall have become effective,
this Declaration of Trust may be terminated or amended in any respect by the
affirmative vote of a majority of the Trustees or by an instrument signed by a
majority of the Trustees.

        11.4.  Merger, Consolidation and Sale of Assets.  The Trust 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, 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 not less than two-
thirds of the Shares of each Series, or by an instrument or instruments in
writing without a meeting, consented to by the holders of not less than two-
thirds of such Shares of each Series, and any such merger, consolidation, sale,
lease or exchange shall be deemed for all purposes to have been accomplished
under and pursuant to the statutes of the Commonwealth of Massachusetts. Any
Series may so merge, consolidate or effect a sale or exchange of assets by the
vote or written consent of not less than two-thirds of the Shares of such
Series. In respect of any such merger, consolidation, sale or exchange of
assets, any Shareholder shall be entitled to rights of appraisal of his Shares
to the same extent as a shareholder of a Massachusetts business corporation in
respect of a merger, consolidation, sale or exchange of assets of a
Massachusetts business corporation, and such rights shall be his exclusive
remedy in respect of his dissent from any such action.

        11.5.  Incorporation.  With the approval of the holders of a majority 
               -------------
of the Shares, 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 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 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
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 

                                      29.
<PAGE>
 
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
organizations or entities.

Each amendment so filed shall be accompanied by a certificate signed and
acknowledged by a Trustee stating that such action as duly taken in a manner

time by a majority of the Trustees and shall, upon filing with the Secretary of
the Commonwealth of Massachusetts, be conclusive evidence of all amendments

Declaration and the various amendments thereto.

        12.2.  Resident Agent.  The Trust shall maintain a resident agent in 
               --------------
the Commonwealth of Massachusetts, which agent shall initially be CT Corporation

designate a successor resident agent, provided, however, that such appointment
shall not become effective until written notice thereof is delivered to the
office of the Secretary of the Commonwealth.

        12.3.  Governing Law.  This Declaration is executed by the Trustees 
               -------------

of said State and reference shall be specifically made to the business
corporation law of the Commonwealth of Massachusetts as to the construction of
matters not specifically covered herein or as to which an ambiguity exists.

        12.4.  Counterparts.  This Declaration may be simultaneously executed 
               ------------

establishment of any Series, (d) the due authorization of the execution of any
instrument or writing, (e) the form of any vote passed at a meeting of Trustees

<PAGE>
 
Trustees, or (h) the existence of any fact or facts which in any manner relate
to the affairs of the Trust or any Series, shall be conclusive evidence as to
the matters so certified in favor of any person dealing with the Trustees and
their successors.

        12.6.  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 counsel, that any of such
provisions is in conflict with 1940 Act, the regulated investment company
provisions of the Internal Revenue Code or with other applicable laws and
regulations, the conflicting provision shall be deemed never to have constituted
a part of this Declaration; provided, however, that such determination shall not
affect any of the remaining provisions of this Declaration or render invalid or
improper any action taken or omitted prior to such determination.

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

        IN WITNESS WHEREOF, the undersigned have caused these presents to be
executed as of the day and year first above written.

VOTED:  That Section 6.2 of Article VI of the Declaration be, and it hereby is,
        amended in its entirety to read as follows:

          6.2. Series Designation. The Trustee, in their discretion from time to
               ------------------
time, may authorize the division of Shares into two or more Series, each Series
relating to a separate portfolio of investments. The different Series 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; provided that all Shares shall be identical except that there may
be variations between different Series as to purchase price, determination of
net asset value, the price, terms and manner of redemption, special and relative
rights as to dividends and on liquidation, conversion rights, and 

                                      2.
<PAGE>
 
conditions under which the several Series shall have separate voting rights. All
references to Shares in this Declaration shall be deemed to be shares of any or
all Series as the context may require.

          The Trustees, in their discretion without a vote of the Shareholders,
may divide the shares of beneficial interest of any Series into classes. In such
event, each class of a Series shall represent interests in the Trust Property of
a Series and have identical voting, dividend, liquidation and other rights and
the same terms and conditions except that expenses related directly or
indirectly to the distribution of the Shares of a class of a Series may be borne
solely by such class (as shall be determined by the Trustees) and, as provided
in Section 10.1, a class of a Series may have exclusive voting rights with
respect to matters relating to the expenses being borne solely by such class.
The bearing of such expenses solely by a class of Shares of a Series shall be
appropriately reflected (in the manner determined by the Trustees) in the net
asset value, dividend and liquidation rights of the Shares of such class of a
Series. The division of the Shares of a Series into classes and the terms and
conditions pursuant to which the Shares of the classes of a Series will be
issued must be made in compliance with the 1940 Act. No division of Shares of a
Series into classes shall result in the creation of a class of Shares having a
preference as to dividends or distributions or a preference in the event of any
liquidation, termination or winding up of the Trust.

          If the Trustee shall divide the Shares into two or more Series, the
following provisions shall be applicable:

          (a)  the number of Shares of each Series and of each class of a Series
that may be issued shall be unlimited.  The Trustees may classify or reclassify
any unissued Shares or any Shares previously issued and required of any Series
into one or more Series that may be established and designated from time to
time.  The Trustees may hold as treasury Shares (of the same or some other
Series),  reissue for such consideration and on such terms as they may
determine, or cancel any Shares of any Series required by the Trust at their
discretion from time to time.

          (b) The power of the Trustees to invest and reinvest the Trust
Property of each Series that may be established shall be governed by Section 3.2
of this Declaration.

          (c) All consideration received by the Trust for the issue or sale of
Shares of a particular Series, together with all assets in which such
consideration is invested or reinvested, all income, earnings, profits, and
proceeds

                                      3.
<PAGE>
 
thereof, including any proceeds derived from the sale, exchange or liquidation
or 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, 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
Trustee 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.

          (d) The assets belonging to each particular Series shall be charged
with the liabilities of the Trust in respect of that Series only and all
expenses, costs, charges and reserves attributable to that Series and shall not
be charged with the liabilities, expenses, costs, charges and reserves
attributable to other Series, 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 holders of all
Series for all purposes. The Trustees shall have full discretion, to the extent
not inconsistent with the 1940 Act, to determine which items shall be treated as
income and which items as capital; and each such determination and allocation
shall be conclusive and binding upon the Shareholders.

          (e) The power of the Trustees to pay dividends and make distributions
with respect to any one or more Series shall be governed by Section 9.2 of this
Declaration. Dividends and distributions on Shares of a particular Series may be
paid with such frequency as the Trustees may determine, to the holders of Shares
of that Series, 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. All
dividends and distributions on Shares of a particular Series shall be
distributed pro rata to the holders of that Series in proportion to the number
of Shares of that Series held by such holders at the date and time of record
established for the payment of such dividends or distributions, except that such
dividends and distributions

                                      4.
<PAGE>
 
shall appropriately reflect expenses related directly or indirectly to the
distribution of Shares of a class of such Series.

          The establishment and designation of any Series of Shares shall be
effective upon the execution by a majority of the then Trustees of an instrument
setting forth the establishment and designation of such Series. Such instrument
shall also set forth any rights and preferences of such Series which are in
addition to the rights and preferences of Shares set forth in this Declaration.
At any time that there are no Shares outstanding of any particular Series
previously established and designated, the Trustees may by an instrument
executed by a majority of their number abolish that Series and the establishment
and designation thereof. Each instrument referred to in this paragraph shall
have the status of an amendment to this Declaration.

VOTED:  That Sections 9.1, 9.2 and 9.4 of Article IX of the Declaration be, and
        they hereby are, amended in their entirety to read as follows:

          9.1. Net Asset Value. The net asset value of each outstanding Share of
               ---------------
each Series of the Trust shall be determined at such time or time on such days
as the Trustees may determine, in accordance with the 1940 Act, with respect to
each Series. The method of determination of net asset value of Shares of each
class of a Series shall be determined by the Trustees and shall be as set forth
in the Prospectus with respect to the applicable Series with any expenses being
borne solely by a class Shares being reflected in the net asset value of such
Shares. The power and duty to make the daily calculations for any Series may be
delegated by the Trustees to the adviser, administrator, manager, custodian,
transfer agent or such other person as the Trustees may determine. The Trustee
may suspend the daily determination of net asset value to the extent permitted
by the 1940 Act.

          9.2. Distributions to Shareholders. The Trustees shall from time to
               -----------------------------
time distribute ratably among the shareholders of any Series such proportion of
the net profits, surplus (including paid-in-surplus), capital, or assets with
respect to such Series held by the Trustees as they deem proper with any
expenses being borne solely by a class of Shares of any Series being reflected
in the net profits or other assets being distributed to such class. Such
distribution may be made in cash or property (including without limitation any
type of obligations of the Trust or any assets thereof), and the Trustees may
distribute ratably among the shareholders of any Series additional Shares of
such Series issuable hereunder in such manner, at such times, and on such terms
as the Trustees may deem proper. Such distributions may be 

                                      5.
<PAGE>
 
among the Shareholders of record at the time of declaring a distribution or
among the Shareholders of record at such later date as the Trustees shall
determine. 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 to meet
obligations of the Trust, or as they 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 of any Series such dividend
reinvestment plans, cash dividend payout plans or related plans as the Trustees
shall deem appropriate for such Series.

          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 to avoid or reduce liability for taxes.

          9.4. Power to Modify Foregoing Procedures. Notwithstanding any of the
               ------------------------------------
foregoing provisions of this Article IX, the Trustees may prescribe, in their
absolute discretion, such other bases and times for determining the per share
net asset value of the Trust's Shares or net income, or the declaration and
payment of dividends and distributions as they deem necessary or desirable or to
enable the Trust to comply with any provision of the 1940 Act, including any
rule or regulation adopted pursuant to Section 22 of the 1940 Act by the
Commission or any securities association registered under the Securities
Exchange Act of 1934, all as in effect now or hereafter amended or modified.

VOTED:  That Sections 10.1 and 10.2 of Article X of the Declaration be, and they
        hereby are, amended in their entirety to read as follows:

          10.1. Voting Powers. The Shareholders shall have power to vote (i) for
                -------------
the removal of Trustees as provided in Section 2.2; (ii) with respect to any
advisory or management contract of a Series as provided in Section 4.1; (iii)
with respect to the amendment of this Declaration as provided in Section 11.3;
(iv) with respect to such additional matters relating to the Trust as may be
required or authorized by the 1940 Act, the laws of the Commonwealth of
Massachusetts or other applicable law or by this Declaration or the By-Laws of
the Trust; and (v) with respect to such additional matters relating to the Trust
as may be properly submitted for Shareholder approval. If the Shares of a Series
shall be 

                                      6.
<PAGE>
 
divided into classes as provided in Article VI hereof, the Shares of each class
shall have identical voting rights except that the Trustees, in their
discretion, may provide a class of a Series with exclusive voting rights with
respect to matters related to expenses being borne solely by such class.

          10.2. Meetings of Shareholders. Special meetings of the Shareholders
                ------------------------
may be called at any time by a majority of the Trustees and shall be called by
any Trustee upon written request of Shareholders of any Series holding in the
aggregate not less than 10% of the outstanding Shares of such Series having
voting rights, such request specifying the purpose or purposes for which such
meeting is to be called. Any such meeting shall be held within or without the
Commonwealth of Massachusetts on such day and at such time as the Trustees shall
designate. The holders of one-third of the outstanding Shares of each Series
present in person or by proxy shall constitute a quorum for the transaction of
any business, except as may otherwise be required by the 1940 Act, the laws of
the Commonwealth of Massachusetts or other applicable law or by this Declaration
or the By-Laws of the Trust. If a quorum is present at a meeting of a particular
Series, the affirmative vote of a majority of the Shares of each Series
represented at the meeting constitutes the action of the Shareholders, unless
the 1940 Act, the laws of the Commonwealth of Massachusetts or other applicable
law, the Declaration or by the By-Laws of the Trust requires a greater number of
affirmative votes. If the Shares of any Series shall be divided into classes
with a class having exclusive voting rights with respect to certain matters, the
aforesaid quorum and voting requirements with respect to action to be taken by
the Shareholders of the class of such Series on such matters shall be applicable
only to the Shares of such class.
          
VOTED:  That Section 11.2 of Article XI of the Declaration be, and it hereby is,
        amended in its entirety to read as follows:

          11.2.  Termination.

          (a) The Trust may be terminated by the affirmative vote of the holders
of not less than two-third of the Shares of each Series of the Trust at any
meeting of Shareholders or by an instrument in writing, without a meeting,
signed by a majority of the Trustees and consented to by the holders of not less
than two-thirds of such Shares. Any Series may be so terminated by vote or
written consent of not less than two-thirds of the Shares of such Series. Upon
the termination of the Trust or any Series,

                                      7.
<PAGE>
 
              (i) The Trust or such Series 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
or such Series and all of the powers of the Trustees under this Declaration
shall continue until the affairs of the Trust or such Series shall have been
wound up, including the power to fulfill or discharge the contracts of the Trust
or such Series, collects its assets, sell, convey, assign, exchange, transfer or
otherwise dispose of all or any part of the remaining Trust Property 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 shall require
approval of the principal terms of the transaction and the nature and amount of
the consideration by vote or consent of the holders of a majority of the Shares
entitled to vote.

            (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 of any Series, in cash or in kind or
partly each, among the Shareholders of such Series and each class of such
Series, according to their respective rights taking into account the proper
allocation of expenses being borne solely by any Series or any class of Shares
of a Series.

          (b) After termination of the Trust or a Series and distribution to the
Shareholders as herein provided, a majority of the Trustees shall execute and
lodge among the records of the Trust an instrument in writing setting forth the
fact of such termination. Upon termination of the Trust, the Trustees shall
thereupon be discharged from all further liabilities and duties hereunder, and
the rights and interests of all Shareholders shall thereupon cease. Upon
termination of any Series, the Trustees shall thereupon be discharged from all
further liabilities and duties with respect to such Series, and the rights and
interests of all Shareholders of such Series shall thereupon cease.

        The undersigned, constituting a majority of the Trustees of Merrill
Lynch Multi-State Municipal Series Trust (the "Trust"), a Massachusetts business
trust, hereby certify that the Trustees of the Trust have duly adopted the
following amendments, as approved by a majority of the shareholders of the
Trust, to the Trust's Declaration of Trust.

VOTED:  That the second paragraph of Section 6.2 of Article VI of the
        Declaration of Trust be, and it hereby is, amended by adding the
        following:

The Trustees may provide that shares of a class will be exchanged for shares
of another class without any act or deed on the part of the holder of shares of
the class being exchanged, whether or not shares of such class are issued and
outstanding, all on terms and conditions as the Trustees may specify.  The
Trustees may redesignate a class or series of shares of beneficial interest or
a portion of a class or series of shares of beneficial interest whether or not
shares of such class or series are issued and outstanding, provided that such
redesignation does not substantially adversely affect the preference,
conversion or other rights, voting powers, restrictions, limitations as to
dividends, qualifications or terms or conditions of redemption of such issued
and outstanding shares of beneficial interest.

VOTED:  That Section 6.3 of Article VI of the Declaration of Trust be, and it
        hereby is, amended in its entirety to read as follows:

        6.3. Rights of Shareholders. The ownership of the Trust Property of

interest therein other than the beneficial interest conferred by their Shares
with respect to a particular Series, 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
<PAGE>
 
shall be personal property giving only the rights in this Declaration
specifically set forth.  The Shares shall not entitle the holder to preference,
preemptive, appraisal, conversion or exchange rights (except for rights of
appraisal specified in Section 11.4 and except as may be specified by the
Trustees in connection with the division of shares into classes or the
redesignation of classes or portions of classes in accordance with Section 6.2).

VOTED:  That Section 10.1 of Article X of the Declaration of Trust be, and it
        hereby is, amended in its entirety to read as follows:

        10.1.  Voting Powers.  The Shareholders shall have power to vote (i) for
               -------------
the removal of Trustees as provided in Section 2.2; (ii) with respect to any
advisory or management contract of a Series as provided in Section 4.1; (iii)
with respect to the amendment of this Declaration as provided in Section 11.3;
(iv) with respect to such additional matters relating to the Trust as may be
required or authorized by the 1940 Act, the laws of the Commonwealth of
Massachusetts or other applicable law or by this Declaration or the By-Laws of
the Trust; and (v) with respect to such additional matters relating to the
Trust as may be properly submitted for Shareholder approval.  If the Shares of
a Series shall be divided into classes as provided in Article VI hereof, the
Shares of each class shall have identical voting rights except that the
Trustees, in their discretion, may provide a class of a Series with exclusive
voting rights with respect to matters related to expenses being borne solely by
such class whether or not shares of such class are issued and outstanding.

        The undersigned, being a majority of the Trustees of the Trust, acting
pursuant to Section 6.1 of the Declaration of Trust, do hereby divide the
shares of beneficial interest of each series of the Trust to create four
classes of shares, within the meaning of said Section 6.1, as follows:

        1.  The four classes of shares are designated "Class A Shares," "Class B
            Shares," "Class C Shares," and "Class D Shares."

        2.  Class A Shares, Class B Shares, Class C Shares and Class D Shares
            shall be entitled to all of the rights and preferences accorded to
            Shares under the Declaration of Trust.

        3.  The purchase price, the method of determination of net asset value,
            the price, terms and manner of redemption, and the relative dividend
            rights of holders of Class A Shares, Class B Shares, Class C Shares
            and Class D Shares shall be established by the Trustees of the Trust
            in accordance with the provisions of the Declaration of Trust and
            shall be set forth in the currently effective prospectus and
            statement of additional information of the Trust relating to each
            series of the Trust, as amended from time to time, contained in the
            Trust's registration statement under the Securities Act of 1933, as
            amended.

        4.  Class A Shares, Class B Shares, Class C Shares and Class D Shares
            shall vote together as a single class except that shares of a class
            may vote separately on matters affecting only that class and shares
            of a class not affected by a matter will not vote on that matter.

        5.  A class of shares of any series of the Trust may be terminated by
            the Trustees by written notice to the Shareholders of the class.

    These By-Laws are made and adopted pursuant to Section 2.6 of the
Declaration of Trust establishing MERRILL LYNCH MULTI-STATE TAX-EXEMPT SERIES
TRUST, dated August 2, 1985, as from time to time amended (hereinafter called
the "Declaration"). All words and terms capitalized in these By-Laws shall have
the meaning or meanings set forth for such words or terms in the Declaration.

                                   ARTICLE I
                                   ---------

                             Shareholder Meetings
                             --------------------

    Section 1.1. Chairman. The Chairman, if any, shall act as chairman at all
                 --------
meetings of the Shareholders; in his absence, the President shall act as
chairman; and in the absence of the Chairman and President, the Trustee or
Trustees present at each meeting may elect a temporary chairman for the meeting,
who may be one of themselves.

    Section 1.2. Proxies; Voting. Shareholders may vote either in person or by
                 ---------------
duly executed proxy and each full share represented at the meeting shall have
one vote, all as provided in Article X of the Declaration. No proxy shall be
valid after

                                      1.
<PAGE>
 
eleven (11) months from the date of its execution, unless a longer period is
expressly stated in such proxy.

    Section 1.3. Closing of Transfer Books and Fixing Record Dates. For the
                 -------------------------------------------------
purpose of determining the Shareholders who are entitled to notice of or to
vote or act at any meeting, including any adjournment thereof, or who are
entitled to participate in any dividends, or for any other proper purpose, the
Trustees may from time to time close the transfer books or fix a record date in
the manner provided in Section 10.4 of the Declaration. If the Trustees do not
prior to any meeting of Shareholders so fix a record date or close the transfer
books, then the date of mailing notice of the meeting or the date upon which the
dividend resolution is adopted, as the case may be, shall be the record date.

    Section 1.4. Inspectors of Election. In advance of any meeting of
                 ----------------------
Shareholders, the Trustees may appoint Inspectors of Election to act at the
meeting or any adjournment thereof. If Inspectors of Election are not so
appointed, the Chairman, if any, of any meeting of Shareholders may, and on the
request of any Shareholder or his proxy shall, Appoint Inspectors of Election of
the meeting. The number of Inspectors shall be either one or three. If appointed
at the meeting on the request Of one or more Shareholders or proxies, a majority

Election. In case any person appointed as inspector fails to appear or fails or
refuses to act, the vacancy may be filled by appointment made by the Trustees in
advance of the convening of the meeting or at the meeting by the person acting
as chairman. The Inspectors of Election shall determine the number of Shares
outstanding, the Shares represented at the meeting, the existence of a quorum,
the authenticity, validity and effect of proxies, shall receive votes, ballots
or consents, shall hear and determine all challenges and questions in any way
arising in connection with the right to vote, shall count and tabulate all votes
or consents, determine the results, and do such other acts as may be proper to
conduct the election or vote with fairness to all Shareholders. If there are
three Inspectors of Election, the decision, act or certificate of a majority is
effective in all respects as the decision, act or certificate of all. On request
of the Chairman, if any, of the meeting, or of any Shareholder or his proxy, the
Inspectors of Election shall make a report in writing of any challenge or
question or matter determined by them and shall execute a certificate of any
facts found by them.

record date of the meeting or the date of closing of transfer books, as the case
may be. Such list of Shareholders shall contain the name of each Shareholder in
alphabetical order and the address and number of Shares owned by such
Shareholder. Shareholders shall have such other rights and procedures of
inspection of the books and records of the Trust as are granted to shareholders
of a Massachusetts business corporation.

from time to time. Regular meetings of the Trustees may be held without call or
notice at such place or places and times as the Trustees may by resolution
provide from time to time.

     Section 2.2. Special Meetings. Special Meetings of the Trustees shall be
                  ----------------

designated in the notice of the meeting.

                  ------
telegram (which term shall include a cablegram) or

the purpose of, any meeting of the Board of Trustees need be stated in the
notice or waiver of notice of such meeting, and no notice need be given of

                          Compensation of the Manager
                          ---------------------------

        (a)  Investment Management Fee.  For the services rendered, the
             -------------------------
facilities furnished and expenses assumed by the Manager, the Trust shall pay to
the Manager at the end of each calendar month a fee based upon the average daily
value of the net assets of the Fund, as determined and computed in accordance
with the description of the determination of net asset value contained in the
Prospectus and Statement of Additional Information, at the annual rate of 0.[ ]
of 1.0% (.[ ]%) of the average daily net assets of the Fund, commencing on the
day following effectiveness hereof.  If this Agreement becomes effective
subsequent to the first day of a month or shall terminate before the last day
of a month, compensation for the part of the month that this Agreement is in
effect shall be prorated in a manner consistent with the calculation of the fee
as set forth above.  Subject to the provisions of subsection (b) hereof,
payment of the Manager's compensation for the preceding month shall be made as
promptly as 

                                       7
<PAGE>
 
possible after completion of the computations contemplated by subsection (b)
hereof.  During any period when the determination of net asset value is
suspended by the Trustees, the net asset value as of the last business day prior
to such suspension shall for this purpose be deemed to be the net asset value at
the close of each succeeding business day until it is again determined.

        (b)  Expense Limitations.  In the event that the operating expenses of
             -------------------
the Fund, including amounts payable to the Manager pursuant to subsection (a)
hereof, for any fiscal year ending on a date on which this Agreement is in
effect exceed the expense limitations applicable to the Fund imposed by
applicable state securities laws or regulations thereunder, as such limitations
may be raised or lowered from time to time, the Manager shall reduce its
management fee by the extent of such excess and, if required pursuant to any
such laws or regulations, will reimburse the Fund in the amount of such excess,
provided, however, to the extent permitted by law, there shall be excluded from
such expenses the amount of any interest, taxes, brokerage commissions and
extraordinary expenses (including but not limited to legal claims and
liabilities and litigation costs and any indemnification related thereto) paid
or payable by the Trust with respect to the Fund. Whenever the expenses of the
Fund exceed a pro rata portion of the applicable annual expense limitations,
the estimated amount of reimbursement under such 

                                       8
<PAGE>
 
limitations shall be applicable as an offset against the monthly payment of the
management fee due to the Manager.  Should two or more such expense limitations
be applicable as of the end of the last business day of the month, that expense
limitation which results in the largest reduction in the Manager's fee shall be
applicable.

Article IV, the term "Manager" shall include any affiliates of the Manager
performing services for the Trust or the Fund contemplated hereby and directors,

                            DISTRIBUTION AGREEMENT


        AGREEMENT made as of the [DATE] day of [MONTH], 199[YEAR], between
MERRILL LYNCH MULTI-STATE MUNICIPAL SERIES TRUST, a Massachusetts business trust
(the "Trust"), and MERRILL LYNCH FUNDS DISTRIBUTOR, INC., a Delaware corporation
(the "Distributor").

                             W I T N E S S E T H :
                             -------------------

        WHEREAS, the Trust is registered under the Investment Company Act of
1940, as amended to date (the "Investment Company Act"), as an open-end
investment company and it is affirmatively in the interest of the Trust to offer
its shares for sale continuously; and

        WHEREAS, the Trustees of the Trust (the "Trustees") are authorized to
establish separate series (the "Series") relating to separate portfolios of
securities, each of which will offer separate classes of shares of beneficial
interest, par value $0.10 per share (collectively referred to as "shares") to
selected groups of purchasers; and

        WHEREAS, the Trustees have established and designated the Merrill Lynch
[STATE] Municipal Bond Fund (the "Fund") as a series of the Trust; and

        WHEREAS, the Distributor is a securities firm engaged in the business of
selling shares of investment companies either directly to purchasers or through
other securities dealers; and
<PAGE>
 
        WHEREAS, the Trust and the Distributor wish to enter into an agreement
with each other with respect to the subscription offering and the continuous
offering of the Class B shares of beneficial interest of the Fund.

        NOW, THEREFORE, the parties agree as follows:

        Section 1.  Appointment of the Distributor.  The Trust hereby appoints
                    ------------------------------   
the Distributor as the principal underwriter and distributor of the Trust to
sell Class B shares of beneficial interest of the Fund (sometimes herein
referred to as "Class B shares") to the public and hereby agrees during the term
of this Agreement to sell shares of the Fund to the Distributor upon the terms
and conditions herein set forth.

        Section 2.  Exclusive Nature of Duties.  The Distributor shall be the
                    --------------------------
exclusive representative of the Trust to act as principal underwriter and
distributor of Class B shares of the Fund, except that:

        (a)  The Trust may, upon written notice to the Distributor, from time to
time designate other principal underwriters and distributors of Class B shares
with respect to areas other than the United States as to which the Distributor
may have expressly waived in writing its right to act as such.  If such
designation is deemed exclusive, the right of the Distributor under this 
Agreement to sell Class B shares in the areas so designated shall terminate,
but this Agreement shall remain otherwise in full effect until terminated in
accordance with the other provisions hereof.

                                       2
<PAGE>
 
        (b)  The exclusive rights granted to the Distributor to purchase Class B
shares from the Trust shall not apply to Class B shares issued in connection
with the merger or consolidation of any other investment company or personal
holding company with the Trust or the acquisition by purchase or otherwise of
all (or substantially all) the assets or the outstanding Class B shares of any
such company by the Trust.

        (c)  Such exclusive rights also shall not apply to Class B shares issued
pursuant to reinvestment of dividends or capital gains distributions.

        (d)  Such exclusive rights also shall not apply to Class B shares issued
pursuant to any reinstatement privilege afforded redeeming shareholders.

        Section 3.  Purchase of Class B Shares from the Trust.  
                    -----------------------------------------
(a)  Prior to the continuous offering of the Class B shares, commencing on a
date agreed upon by the Trust and the Distributor, it is contemplated that the
Distributor will solicit subscriptions for Class B shares during a subscription
period which shall last for such period as may be agreed upon by the parties
hereto.  The subscriptions will be payable within five  business days after the
termination of the subscription period, at which time the Fund will commence
operations.

        (b)  After the Fund commences operations, the Trust will commence an
offering of Class B shares of the Fund and thereafter the Distributor shall
have the right to buy from the Trust the Class B shares needed, but not more
than the Class B shares 

                                       3
<PAGE>
 
needed (except for clerical errors in transmission), to fill unconditional
orders for Class B shares of the Fund placed with the Distributor by investors
or securities dealers. The price which the Distributor shall pay for the Class B
shares so purchased from the Trust shall be the net asset value, determined as
set forth in Section 3(d) hereof.

        (c)  The Class B shares are to be resold by the Distributor to investors
at net asset value, as set forth in Section 3(d) hereof, or to securities
dealers having agreements with the Distributor upon the terms and conditions set
forth in Section 7 hereof.

        (d)  The net asset value of Class B shares of the Fund shall be
determined by the Trust or any agent of the Trust in accordance with the method
set forth in the prospectus and statement of additional information relating to
the Fund and guidelines established by the Board of Trustees.

        (e)  The Trust shall have the right to suspend the sale of Class B
shares at times when redemption is suspended pursuant to the conditions set
forth in Section 4(b) hereof. The Trust shall also have the right to suspend the
sale of Class B shares if trading on the New York Stock Exchange shall have been
suspended, if a banking moratorium shall have been declared by Federal or New
York authorities, or if there shall have been some other event, which, in the
judgment of the Trust, makes it impracticable or inadvisable to sell the shares.

                                       4
<PAGE>
 
        (f)  The Trust, or any agent of the Trust designated in writing by the
Trust, shall be promptly advised of all purchase orders for Class B shares
received by the Distributor.  Any order may be rejected by the Trust; provided,
however, that the Trust will not arbitrarily or without reasonable cause refuse
to accept or confirm orders for the purchase of Class B shares.  The Trust (or
its agent) will confirm orders upon their receipt, will make appropriate book
entries and, upon receipt by the Trust (or its agent) of payment therefor, will
deliver deposit receipts or certificates for such Class B shares pursuant to
the instructions of the Distributor.  Payment shall be made to the Trust in New
York Clearing House funds.  The Distributor agrees to cause such payment and
such instructions to be delivered promptly to the Trust (or its agent).

        Section 4.  Repurchase or Redemption of Class B Shares by the Trust. (a)
                    -------------------------------------------------------
Any of the outstanding Class B shares may be tendered for redemption at any
time, and the Trust agrees to repurchase or redeem the Class B shares so
tendered in accordance with its obligations as set forth in Article VIII of its
Declaration of Trust, as amended from time to time, and in accordance with the
applicable provisions set forth in the prospectus and statement of additional
information relating to the Fund.  The price to be paid to redeem or repurchase
the Class B shares shall be equal to the net asset value calculated in
accordance with the provisions of Section 3(d) hereof, less the redemption fee
or other charge, if any, set forth in the 

                                       5
<PAGE>
 
prospectus and statement of additional information relating to the Fund. All
payments by the Trust hereunder shall be made in the manner set forth below.

        The Trust shall pay the total amount of the redemption price as defined
in the above paragraph pursuant to the instructions of the Distributor on or
before the seventh business day subsequent to its having received the notice of
redemption in proper form. The proceeds of any redemption of shares shall be
paid by the Trust as follows: (i) any applicable contingent deferred sales
charge shall be paid to the Distributor and (ii) the balance shall be paid to or
for the account of the shareholder, in each case in accordance with the
applicable provisions of the prospectus and statement of additional information.

        (b)  Redemption of Class B shares or payment may be suspended at times
             -----------
when the New York Stock Exchange is closed, when trading on said Exchange is
closed, when trading on said Exchange is restricted, when an emergency exists as
a result of which disposal by the Trust of securities owned by it is not
reasonably practicable or it is not reasonably practicable for the Trust fairly
to determine the value of the net assets of the Fund, or during any other period
when the Securities and Exchange Commission, by order, so permits.

        Section 5.  Duties of the Trust.  (a)  The Trust shall furnish to the
                    -------------------
Distributor copies of all information, financial statements and other papers
which the Distributor may reasonably request for use in connection with the
distribution of Class B 

                                       6
<PAGE>
 
shares of the Fund, and this shall include, upon request by the Distributor, one
certified copy of all financial statements prepared for the Trust by independent
public accountants.  The Trust shall make available to the Distributor such
number of copies of its prospectus and statement of additional information
relating to the Fund as the Distributor shall reasonably request.

        (b)  The Trust shall take, from time to time, but subject to the
necessary approval of the shareholders, all necessary action to fix the number
of authorized shares and such steps as may be necessary to register the same
under the Securities Act of l933, as amended (the "Securities Act"), to the end
that there will be available for sale such number of Class B shares as the
Distributor reasonably may be expected to sell.

        (c)  The Trust shall use its best efforts to qualify and maintain the
qualification of an appropriate number of Class B shares for sale under the
securities laws of such states as the Distributor and the Trust may approve. 
Any such qualification may be withheld, terminated or withdrawn by the Trust at
any time in its discretion.  As provided in Section 8(c) hereof, the expense of
qualification and maintenance of qualification shall be borne by the Trust. 
The Distributor shall furnish such information and other material relating to
its affairs and activities as may be required by the Trust in connection with
such qualification.

                                       7
<PAGE>
 
        (d)  The Trust will furnish, in reasonable quantities upon request by
the Distributor, copies of annual and interim reports relating to the Fund.

        Section 6.  Duties of the Distributor.  (a)  The Distributor shall
                    -------------------------
 devote reasonable time and effort to effect sales of Class B shares of the
 Fund, but shall not be obligated to sell any specific number of shares. The
 services of the Distributor to the Trust hereunder are not to be deemed
 exclusive and nothing herein contained shall prevent the Distributor from
 entering into like arrangements with other investment companies so long as the
 performance of its obligations hereunder is not impaired thereby.

        (b)  In selling the Class B shares of the Fund, the Distributor shall
use its best efforts in all respects duly to conform with the requirements of
all Federal and state laws relating to the sale of such securities.  Neither the
Distributor nor any selected dealer, as defined in Section 7 hereof, nor any
other person is authorized by the Trust to give any information or to make any
representations, other than those contained in the registration statement or
related prospectus and statement of additional information and any sales
literature specifically approved by the Trust.

        (c)  The Distributor shall adopt and follow procedures, as approved by
the officers of the Trust, for the confirmation of sales to investors and
selected dealers, the collection of amounts payable by investors and selected
dealers on such sales, and the cancellation of unsettled transactions, as may be

                                       8
<PAGE>
 
necessary to comply with the requirements of the National Association of
Securities Dealers, Inc. (the "NASD"), as such requirements may from time to
time exist.

        Section 7.  Selected Dealer Agreements.  (a)  The Distributor shall have
                    --------------------------
the right to enter into selected dealer agreements with securities dealers of
its choice ("selected dealers") for the sale of Class B shares; provided, that
the Trust shall approve the forms of agreements with dealers.  Class B shares
sold to selected dealers shall be for resale by such dealers only at net asset
value determined as set forth in Section 3(d) hereof.  The form of agreement
with selected dealers to be used during the subscription period described in
Section 3(a) is attached hereto as Exhibit A and the initial form of agreement
with selected dealers to be used in the continuous offering of the shares is
attached hereto as Exhibit B.

        (b)  Within the United States, the Distributor shall offer and sell
Class B shares only to such selected dealers as are members in good standing of
the NASD.

        Section 8.  Payment of Expenses.  (a)  The Trust shall bear all costs
                    -------------------
and expenses of the Fund, including fees and disbursements of its counsel and
auditors, in connection with the preparation and filing of any required
registration statements and/or prospectuses and statements of additional
information under the Investment Company Act, the Securities Act, and all
amendments and supplements thereto, and preparing and mailing annual and interim
reports and proxy materials to Class B 

                                       9
<PAGE>
 
shareholders (including but not limited to the expense of setting in type any
such registration statements, prospectuses, statements of additional
information, annual or interim reports or proxy materials).

        (b)  The Distributor shall be responsible for any payments made to
selected dealers as reimbursement for their expenses associated with payments of
sales commissions to financial consultants.  In addition, after the
prospectuses, statements of additional information and annual and interim
reports have been prepared and set in type, the Distributor shall bear the costs
and expenses of printing and distributing any copies thereof which are to be
used in connection with the offering of Class B shares to selected dealers or
investors pursuant to this Agreement.  The Distributor shall bear the costs and
expenses of preparing, printing and distributing any other literature used by
the Distributor or furnished by it for use by selected dealers in connection
with the offering of the Class B shares for sale to the public and any expenses
of advertising incurred by the Distributor in connection with such offering. It
is understood and agreed that, so long as the Fund's Class B Distribution Plan
pursuant to Rule 12b-1 under the Investment Company Act remains in effect, any
expenses incurred by the Distributor hereunder may be paid from amounts
recovered by it from the Fund under such Plan.

                                       10
<PAGE>
 
        (c)  The Trust shall bear the cost and expenses of qualification of the
Class B shares for sale pursuant to this Agreement, and, if necessary or
advisable in connection therewith, of qualifying the Trust as a broker or
dealer, in such states of the United States or other jurisdictions as shall be
selected by the Trust and the Distributor pursuant to Section 5(c) hereof and
the cost and expenses payable to each such state for continuing qualification
therein until the Trust decides to discontinue such qualification pursuant to
Section 5(c) hereof.

        Section 9.  Indemnification.  (a)  The Trust shall indemnify and hold
                    ---------------
harmless the Distributor and each person, if any, who controls the Distributor
against any loss, liability, claim, damage or expense (including the reasonable
cost of investigating or defending any alleged loss, liability, claim, damage
or expense and reasonable counsel fees incurred in connection therewith), as
incurred, arising by reason of any person acquiring any Class B shares, which
may be based upon the Securities Act, or on any other statute or at common law,
on the ground that the registration statement or related prospectus and
statement of additional information relating to the Fund, as from time to time
amended and supplemented, or an annual or interim report to Class B
shareholders of the Fund, includes an untrue statement of a material fact or
omits to state a material fact required to be stated therein or necessary in
order to make the statements therein not misleading, unless such statement or
omission was made in reliance upon, and in conformity with, 

                                       11
<PAGE>
 
information furnished to the Trust in connection therewith by or on behalf of
the Distributor; provided, however, that in no case (i) is the indemnity of the
Trust in favor of the Distributor and any such controlling persons to be deemed
to protect such Distributor or any such controlling persons thereof against any
liability to the Trust or its security holders to which the Distributor or any
such controlling persons would otherwise be subject by reason of willful
misfeasance, bad faith or gross negligence in the performance of their duties
or by reason of the reckless disregard of their obligations and duties under
this Agreement; or (ii) is the Trust to be liable under its indemnity agreement
contained in this paragraph with respect to any claim made against the
Distributor or any such controlling persons, unless the Distributor or such
controlling persons, as the case may be, shall have notified the Trust in
writing within a reasonable time after the summons or other first legal process
giving information of the nature of the claim shall have been served upon the
Distributor or such controlling persons (or after the Distributor or such
controlling persons shall have received notice of such service on any
designated agent), but failure to notify the Trust of any such claim shall not
relieve it from any liability which it may have to the person against whom such
action is brought otherwise than on account of its indemnity agreement
contained in this paragraph.  The Trust will be entitled to participate at its
own expense in the defense, or, if it so elects, to assume the defense of any
suit brought to 

                                       12
<PAGE>
 
enforce any such liability, but if the Trust elects to assume the defense, such
defense shall be conducted by counsel chosen by it and satisfactory to the
Distributor or such controlling person or persons, defendant or defendants in
the suit.  In the event the Trust elects to assume the defense of any such suit
and retain such counsel, the Distributor or such controlling person or persons,
defendant or defendants in the suit, shall bear the fees and expenses, as
incurred, of any additional counsel retained by them, but, in case the Trust
does not elect to assume the defense of any such suit, it will reimburse the
Distributor or such controlling person or persons, defendant or defendants in
the suit, for the reasonable fees and expenses, as incurred, of any counsel
retained by them.  The Trust shall promptly notify the Distributor of the
commencement of any litigation or proceedings against it or any of its officers
or Trustees in connection with the issuance or sale of any of the Class B
shares.

        (b)  The Distributor shall indemnify and hold harmless the Trust and
each of its Trustees and officers and each person, if any, who controls the
Trust against any loss, liability, claim, damage or expense, as incurred,
described in the foregoing indemnity contained in subsection (a) of this
Section, but only with respect to statements or omissions made in reliance upon,
and in conformity with, information furnished to the Trust in writing by or on
behalf of the Distributor for use in connection with the registration statement
or related prospectus and statement of additional information, as from time to
time 

                                       13
<PAGE>
 
amended, or the annual or interim reports to shareholders.  In case any action
shall be brought against the Trust or any person so indemnified, in respect of
which indemnity may be sought against the Distributor, the Distributor shall
have the rights and duties given to the Trust, and the Trust and each person so
indemnified shall have the rights and duties given to the Distributor by the
provisions of subsection (a) of this Section 9.

        Section 10.  Duration and Termination of this Agreement.  This Agreement
                     ------------------------------------------
shall become effective as of the date first above  written and shall remain in
force until [DATE] and thereafter, but only so long as such continuance is
specifically approved at least annually by (i) the Trustees, or by the vote of
a majority of the outstanding Class B voting securities of the Fund, and (ii)
by the vote of a majority of those Trustees who are not parties to this
Agreement or interested persons of any such party cast in person at a meeting
called for the purpose of voting on such approval.

        This Agreement may be terminated at any time, without the payment of any

                            -----------------------

Gentlemen:

        Merrill Lynch Funds Distributor, Inc. (the "Distributor") has an
agreement with Merrill Lynch Multi-State Municipal Series Trust, a Massachusetts
business trust (the "Trust"), pursuant to which it acts as the distributor for
the sale of Class B shares of beneficial interest, par value $0.10 per share
(herein referred to as "Class B shares"), of the Trust relating to Merrill Lynch
[STATE] Municipal Bond Fund (the "Fund"), and as such has the right to
distribute Class B shares of the Fund for resale. The Trust is an open-end
investment company registered under the Investment Company Act of 1940, as
amended (the "Investment Company Act"), and the Fund's Class B shares being
offered to the public are registered under the Securities Act of 1933, as
amended (the "Securities Act").  Such Class B Shares and certain of the terms on
which they are being offered are more fully described in the enclosed Prospectus
and Statement of Additional Information.  You have received a copy of the Class
B Shares Distribution Agreement (the "Distribution Agreement") between ourself
and the Trust and reference is made herein to certain provisions of such
Distribution Agreement.  This Agreement relates solely to the subscription
period described in Section 3(a) of such Distribution Agreement.  Subject to the
foregoing, as principal, we offer to sell to you, as a member of the Selected
Dealers Group, Class B shares of the Fund upon the following terms and
conditions:

        1. The subscription period referred to in Section 3(a) of the
Distribution Agreement will continue through [DATE]. The subscription period may
be extended upon agreement between the Trust and the Distributor. Subject to the
provisions of such Section and the conditions contained herein, we will sell to
you on the fifth business day following the termination of the subscription
period, or such other date as we may advise (the "Closing Date"), such number of
Class B shares as to which you have placed orders with us not later than 5:00
P.M. on the second full business day preceding the Closing Date.
<PAGE>
 
        2.  In all sales of these Class B shares to the public you shall act as
dealer for your own account, and in no transaction shall you have any authority
to act as agent for the Trust, for us or for any other member of the Selected
Dealers Group.

        3.  You shall not place orders for any of the Class B shares unless you
have already received purchase orders for such Class B shares at the applicable
public offering prices and subject to the terms hereof and of the Distribution
Agreement.  All orders are subject to acceptance by the Distributor or the
Trust in the sole discretion of either.  The minimum initial and subsequent
purchase requirements are as set forth in the Prospectus, as amended from time
to time.  You agree that you will not offer or sell any of the Class B shares
except under circumstances that will result in compliance with the applicable
Federal and state securities laws and that in connection with sales and offers
to sell Class B shares you will furnish to each person to whom any such sale or
offer is made a copy of the Prospectus and, if requested, the Statement of
Additional Information (as then amended or supplemented) relating to the Fund
and will not furnish to any person any information relating to the Class B
shares of the Fund which is inconsistent in any respect with the information
contained in the Prospectus and Statement of Additional Information (as then
amended or supplemented) or cause any advertisement to be published in any
newspaper or posted in any public place without our consent and the consent of
the Trust.

        4.  Payment for Class B shares purchased by you is to be made by Federal
funds wire or by certified or official bank check at the office of
Merrill Lynch Funds Distributor, Inc., Box 9011 Princeton, New Jersey 08543-
9011, payable to the order of Merrill Lynch Funds Distributor, Inc., against
delivery by us of non-negotiable share deposit receipts ("Receipts") issued by
Financial Data Services, Inc., as shareholder servicing agent, acknowledging the
deposit with it of the Class B shares so purchased by you. You agree that as
promptly as practicable after the delivery of such Class B shares you will issue
appropriate written transfer instructions to the Trust or to the shareholder
servicing agent as to the purchasers to whom you sold the Class B shares.

        5.  No person is authorized to make any representations concerning Class
B shares of the Fund except those contained in the current Prospectus and
Statement of Additional Information relating to the Fund and in such printed
information subsequently issued by us or the Trust as information supplemental
to such 

                                      A-2
<PAGE>
 
Prospectus and Statement of Additional Information.  In purchasing Class
B shares through us you shall rely solely on the representations contained in
the Prospectus and Statement of Additional Information and supplemental
information above mentioned.  Any printed information which we furnish you other
than the Fund's Prospectus and Statement of Additional Information, periodic
reports and proxy solicitation material are our sole responsibility and not the
responsibility of the Trust, and you agree that the Trust shall have no
liability or responsibility to you in these respects unless expressly assumed in
connection therewith.

        6.  You agree to deliver to each of the purchasers making purchases from
you a copy of the then current Prospectus and, if requested, the Statement of
Additional Information at or prior to the time of offering or sale and you
agree thereafter to deliver to such purchasers copies of the annual and interim
reports and proxy solicitation materials relating to the Fund.  You further
agree to endeavor to obtain Proxies from such purchasers.  Additional copies of
the Prospectus and Statement of Additional Information, annual or interim
reports and proxy solicitation materials of the Trust will be supplied to you
in reasonable quantities upon request.

        7.  We reserve the right in our discretion, without notice, to suspend
sales or withdraw the offering of Class B shares entirely.  Each party hereto
has the right to cancel this Agreement upon notice to the other party.

        8.  We shall have full authority to take such action as we may deem
advisable in respect of all matters pertaining to the continuous offering.  We
shall be under no liability to you except for lack of good faith and for
obligations expressly assumed by us herein.  Nothing contained in this
paragraph is intended to operate as, and the provisions of this paragraph shall
not in any way whatsoever constitute, a waiver by you of compliance with any
provision of the Securities Act or of the rules and regulations of the
Commission issued thereunder.

        9.  You represent that you are a member of the National Association of
Securities Dealers, Inc. and, with respect to any sales in the United States,
we both hereby agree to abide by the Rules of Fair Practice of such Association.

        10.  Upon application to us, we will inform you as to the states in
which we believe the Class B shares have been qualified for sale under, or are
exempt from the requirements of, the respective securities laws of such states,
but we assume no 

                                      A-3
<PAGE>
 
responsibility or obligation as to your right to sell Class B shares in any
jurisdiction.  We will file with the Department of State in New York a Further
State Notice with respect to the Class B shares, if necessary.
 
        11.  All communications to us should be sent to the address below.  Any
notice to you shall be duly given if mailed or telegraphed to you at the
address specified by you below.

        12.  You agree that you will not sell any Class B shares of the Trust to
any account over which you exercise discretionary authority.

        13.  This Agreement shall terminate at the close of business on the
Closing Date, unless earlier terminated, provided, however, this Agreement shall
continue after termination for the purpose of settlement of accounts hereunder.

Merrill Lynch Pennsylvania Municipal Bond Fund of
  Merrill Lynch Multi-State Municipal Series Trust
P.O. Box 9011
Princeton, New Jersey 08543-9011

Dear Sirs:

     This opinion is furnished in connection with the registration by Merrill 
Lynch Multi-State Municipal Series Trust, a Massachusetts business trust (the 
"Trust"), of 1,214,480 shares of beneficial interest, par value $0.10 per 
share (the "Shares"), of the Merrill Lynch Pennsylvania Municipal Bond Fund, a
series of the Trust, under the Securities Act of 1933 pursuant to a registration
statement on Form N-1A (File No. 33-35442), as amended (the "Registration
Statement").

     As counsel for the Trust, we are familiar with the proceedings taken by it
in connection with the authorization, issuance and sale of the Shares. In 
addition, we have examined and are familiar with the Declaration of Trust of the
Trust, as amended, the By-Laws of the Trust and such other documents as we have 
deemed relevant to the matters referred to in this opinion.

     Based upon the foregoing, we are of the opinion that the Shares, upon 
issuance and sale in the manner referred to in the Registration Statement for 
consideration not less than the par value thereof, will be legally issued, fully
paid and nonassessable shares of beneficial interest, except that shareholders 
of the Trust may under certain circumstances be held personally liable for the 
Trust's obligations.

     In rendering this opinion, we have relied as to matters of Massachusetts 
law upon an opinion of Bingham, Dana & Gould rendered to the Trust.

     We hereby consent to the filing of this opinion as an exhibit to the 
Registration Statement and to the use of our name in the Prospectus and 
Statement of Additional Information constituting parts thereof.

                                                    /s/ Brown & Wood
