                MERRILL LYNCH CALIFORNIA MUNICIPAL SERIES TRUST
   P.O. BOX 9011, PRINCETON, NEW JERSEY 08543-9011 - PHONE NO. (609) 282-2800

    Merrill Lynch California Municipal Bond Fund (the "Fund") is a diversified
mutual fund seeking to provide shareholders with as high a level of income
exempt from Federal and California income taxes as is consistent with prudent
investment management. The Fund invests primarily in a diversified portfolio of
long-term investment grade obligations issued by or on behalf of the State of
California, 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 from Federal and
California income taxes ("California Municipal Bonds"). Dividends paid by the
Fund are exempt from Federal and California income taxes to the extent derived
from California 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 11.
    
                            ------------------------
 
    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 3.
 
    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 selected 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".

     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
Commission regulations. THE EXAMPLE SHOULD NOT BE CONSIDERED A REPRESENTATION OF
PAST OR FUTURE EXPENSES OR ANNUAL RATES 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 Conduct
Rules of the National Association of Securities Dealers, Inc. (the "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 PRICINGSM SYSTEM
 
     The Fund offers four classes of shares under the Merrill Lynch Select
PricingSM 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 PricingSM System is used by more
 
                                        3
<PAGE>   6
 
   
than 50 registered investment companies advised by Merrill Lynch Asset
Management, L.P. ("MLAM") or Fund Asset Management, L.P. ("FAM" or the
"Manager"), an affiliate of MLAM. Funds advised by MLAM or FAM which utilize the
Merrill Lynch Select Pricing(SM) System 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
CDSCs, distribution fees 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, 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 or her particular circumstances. More
detailed information as to each class of shares is set forth under "Purchase of
Shares".

(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 and waived for purchases of Class A
    shares in connection with certain fee-based programs. 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. Such CDSC may be waived in connection with redemptions to fund
    participation in certain fee-based programs. See "Class A" and "Class D"
    below.
    
   
(4) The CDSC may be modified in connection with redemptions to fund
    participation in certain fee-based programs.
    
   
(5) 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.
    
   
(6) The CDSC may be waived in connection with redemptions to fund participation
    in certain fee-based programs.
    
 
   
 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 of the Fund in a
          shareholder account are entitled to purchase additional Class A shares
          of the Fund in that account. Other eligible investors include
          participants in certain fee-based programs. In addition, Class A
          shares will be offered at net asset value 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 and waived for purchases of Class A shares in
          connection with certain fee-based programs. 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 1.0% CDSC if
          the shares are redeemed within one year after purchase. Such CDSC may
          be waived in connection with redemptions to fund participation in
          certain fee-based programs. 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 four years of purchase. Such CDSC may be modified in
          connection with redemptions to fund participation in certain fee-based
          programs. 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
    
 
                                        5
<PAGE>   8
 
       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 and for
       certain retirement plans 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 of 1.0% if they are redeemed within one year of purchase.
          Such CDSC may be waived in connection with redemptions to fund
          participation in certain fee-based programs. Although Class C shares
          are subject to a CDSC for only one year (as compared to four years for
          Class B), Class C shares have no conversion feature and, accordingly,
          an investor that purchases Class C shares will be subject to account
          maintenance fees and higher distribution fees that will be imposed on
          Class C shares for an indefinite period subject to annual approval by
          the Trust'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. Such CDSC may be waived in
         connection with redemptions to fund participation in certain fee-based
         programs. The schedule of initial sales charges and reductions for
         Class D shares is the same as the schedule for Class A shares, except
         that there is no waiver for purchases of Class D shares in connection
         with certain fee-based programs. Class D shares also will be issued
         upon conversion of Class B shares as described above under "Class B".
         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
PricingSM System that the investor believes is most beneficial under his or her
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 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 CDSCs 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 and, in the case of Class D shares, the account
maintenance fee. 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, Class C and Class D share 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
    
 
                                        6
<PAGE>   9
 
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 qualify for a reduction in initial sales charges. Both
Class B and Class C shares are subject to ongoing account maintenance fees and
distribution 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 of 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 of 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 California income taxes as is
consistent with prudent investment management. The Fund seeks to achieve its
objective while providing investors with the opportunity to invest in a
diversified portfolio of securities consisting primarily of long-term
obligations issued by or on behalf of the State of California, its political
subdivisions, agencies and instrumentalities and obligations of other qualifying
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
California income taxes. Obligations exempt from Federal income taxes are
referred to herein as "Municipal Bonds" and obligations exempt from both Federal
and California income taxes are referred to herein as "California Municipal
Bonds". Unless otherwise indicated, references to Municipal Bonds shall be
deemed to include California Municipal Bonds. The Fund at all times, except
during temporary defensive periods, will maintain at least 65% of its total
assets invested in California Municipal Bonds. The investment objective of the
Fund as set forth in the first sentence of this paragraph is a fundamental
policy and may not be changed without shareholder approval. At times, the Fund
may seek to hedge its portfolio through the use of futures transactions to
reduce volatility in the net asset value of Fund shares.
    
 
   
     Municipal Bonds may include several types of bonds. The Fund may also
invest in variable rate demand obligations ("VRDOs"). 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 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, Inc. ("Moody's") (currently Aaa, Aa, A and Baa),
Standard & Poor's Ratings Services ("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, 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 or
which, in the Manager's judgment, possess similar credit characteristics. 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
    
 
                                       11
<PAGE>   14
 
   
operating history, the quality of its management and regulatory matters. See
"Investment Objective and Policies" in the Statement of Additional Information
for 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
Municipal Bonds but also the creditworthiness of the financial institution.
 
     The value of Municipal Bonds may fall when interest rates rise and rise
when interest rates fall. In general, Municipal Bonds with longer maturities
will be subject to greater volatility resulting from interest rate fluctuations
than will similar obligations with shorter maturities.
 
   
     The Fund's investments include both 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, the 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
period 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
determinations.
    
 
   
     The Fund ordinarily does not intend to realize investment income not exempt
from Federal and California income taxes. However, to the extent that suitable
California 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 California, income taxes. 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 also 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
    
 
                                       12
<PAGE>   15
 
   
(the "1940 Act"). Other Non-Municipal Tax-Exempt Securities could include trust
certificates or other derivative 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 California Municipal Bonds. For 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 total assets. The Temporary Investments,
VRDOs and Participating VRDOs in which the Fund may invest 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 total assets invested in securities the
interest on which is exempt from Federal income 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 total 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 California
income taxes and to own shares in a professionally managed portfolio consisting
primarily of long-term California 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 of investing in the Fund 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 fees.
    
 
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".
 
                                       13
<PAGE>   16
 
     Moreover, the Fund ordinarily will invest at least 65% of its total assets
in California Municipal Bonds, and therefore it is more susceptible to factors
adversely affecting issuers of California Municipal Bonds than is a municipal
bond mutual fund that is not concentrated in issuers of California Municipal
Bonds to this degree. Since the start of the 1990-91 fiscal year, the State of
California has faced the worst economic, fiscal and budget conditions since the
1930's. On July 5, 1994, all three of the rating agencies rating the State of
California's long-term debt lowered their ratings of the State of California's
general obligation bonds. Moody's lowered its rating from "Aa" to "A1", Standard
& Poor's lowered its rating from "A+" to "A" and termed its outlook as "stable",
and Fitch lowered its rating from "AA" to "A". No assurance can be given that
such ratings will not be lowered in the future. Although a steady upturn has
been underway since 1994, pre-recession job levels are not expected to be
reached until later in the decade. The Manager does not believe that the current
economic conditions in California will have a significant adverse effect on the
Fund's ability to invest in high quality California Municipal Bonds. For a
discussion of economic and other conditions in the State of California, see
Appendix I in 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 or refinance various
privately operated facilities, including certain local facilities for water
supply, gas, electricity, sewage or solid waste disposal. For purposes of this
Prospectus, such obligations are Municipal Bonds if the interest paid thereon is
excluded from gross income for purposes of Federal income taxation and
California Municipal Bonds, if the interest thereon is exempt from Federal and
California income tax, even though such bonds may be industrial development
bonds ("IDBs") or "private activity bonds" as discussed below.
    
 
   
     The two principal classifications of Municipal Bonds are "general
obligation" bonds 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 its faith, credit and
taxing power for the repayment of principal and the payment of interest. The
taxing power of any governmental entity may be limited, however, by provisions
of its state constitution or laws, and an entity's creditworthiness will depend
on many factors, including potential erosion of its tax base due to population
declines, natural disasters, declines in the state's industrial or commercial
base or inability to attract new industries or businesses, 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's 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 size and stability of
the issuer's 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 payments 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.
    
 
                                       14
<PAGE>   17
 
   
     The Fund may purchase IDBs or private activity bonds. IDBs or private
activity bonds are, in most cases, tax-exempt securities issued by states,
municipalities or public authorities to provide funds, usually through a loan or
lease arrangement, to a private entity for the purpose of financing construction
or improvement of a facility to be used by the entity. Such bonds are secured
primarily by revenues derived from loan repayments or lease payments due from
the entity which may or may not be guaranteed by a parent company or otherwise
secured. IDBs and private activity bonds are generally not secured by a pledge
of the taxing power of the issuer of such bonds. Therefore, an investor should
be aware that repayment of such bonds depends on the revenues of a private
entity and be aware of the risks that such an investment may entail. Continued
ability of an entity 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 entity, capital structure, demand for its products or services,
competition, general economic conditions, government regulation and the entity's
dependence on revenues for the operation of the particular facility being
financed. The Fund may invest more than 25% of its total assets in IDBs or
private activity bonds. The Fund may also 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, 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 the 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.
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
potential investment rewards, to hedge other portfolio positions or to vary the
degree of investment leverage relatively efficiently under different market
conditions.
    
 
     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
 
                                       15
<PAGE>   18
 
   
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 relatively new 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 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.
    
 
   
     The value of bonds and other fixed-income obligations may fall when
interest rates rise and rise when interest rates fall. In general, bonds and
other fixed-income obligations with longer maturities will be subject to greater
volatility resulting from interest rate fluctuations than will similar
obligations with shorter maturities. Under normal conditions, it is generally
anticipated that the Fund's average weighted maturity would be in excess of ten
years.
    
 
     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.
    
 
                                       16
<PAGE>   19
 
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 liquid securities 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
purposes of hedging its investments in Municipal Bonds against declines in value
and hedging 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
financial 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
financial 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, U.S. Treasury notes, Government National
Mortgage Association ("GNMA") Certificates and three-month U.S. Treasury bills.
 
                                       17
<PAGE>   20
 
     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 financial futures contracts and the Municipal Bonds in which the Fund
invests to make such hedging appropriate.
 
     Utilization of financial futures transactions and options thereon involves
the risk of imperfect correlation in movements in the price of financial futures
contracts and movements in the price of the security which is the subject of the
hedge. If the price of the financial 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 financial 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
financial futures contracts on U.S. Government securities and options on such
financial 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 ("CFTC"), 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 financial 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 financial futures contracts and options. (However, as stated above, the
Fund intends to engage in options and financial 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 financial 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 liquid 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 financial
futures contracts, thereby ensuring that the use of such financial futures
contract is unleveraged. It is not anticipated that transactions in financial
futures contracts will have the effect of increasing portfolio turnover.
    
 
     Although certain risks are involved in options and financial futures
transactions, the Manager believes that, because the Fund will engage in
financial 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 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.
 
                                       18
<PAGE>   21
 
     The liquidity of a secondary market in a financial 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
reached and exceeded the daily limit on a number of consecutive trading days.
 
     The successful use of transactions in financial 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 financial 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 of the Fund 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 which means the lesser
of (i) 67% of the shares represented at a meeting at which more than 50% of the
outstanding shares are represented or (ii) more than 50% of the outstanding
shares. Among its fundamental policies, the Fund may not invest more than 25% of
its total assets, taken at market value at the time of each investment, in
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.) Investment restrictions and policies that are
non-fundamental policies may be changed by the Board of Trustees without
shareholder approval. As a non-fundamental policy, the Fund may not 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
    
 
                                       19
<PAGE>   22
 
   
extraordinary or emergency purposes. In addition the Fund will not purchase
securities while borrowings are outstanding.
    
 
   
     As a non-fundamental policy, the Fund will not 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 Trust has
otherwise determined to be liquid pursuant to applicable law.
    
 
   
     The Fund's investments will be limited so as to qualify for the special tax
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 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. The Fund is classified as "diversified" under the 1940 Act and
must satisfy the foregoing 5% and 10% requirements with respect to 75% of its
total assets.
    
 
   
     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 services. The Manager or MLAM acts as the
investment adviser to more than 130 other registered investment companies. MLAM
also provides investment advisory services to individual and institutional
accounts. As of November 30, 1996, the Manager and MLAM had a total of
approximately $223.7 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 of the office space, facilities,
equipment and necessary personnel for management of the Fund.
    
 
   
     Walter O'Connor became the Portfolio Manager of the Fund in 1995 and is
responsible for the day-to-day management of the Fund's investment portfolio. He
has been a Vice President of MLAM since 1993 and was an Assistant Vice President
thereof from 1991 to 1993. Prior thereto, he was an Assistant Vice President of
Prudential Securities from 1984 to 1991.
    
 
   
     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 compensation at the annual rate of 0.55% of the average daily net assets
of the Fund. Effective December 23, 1987, the Manager voluntarily agreed to
waive the amount of compensation set forth in the Management Agreement and
instead has agreed 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 portion
of the average daily net assets not exceeding $500 million; 0.525% of the
portion of the average daily net assets exceeding $500 million but not exceeding
$1.0 billion and 0.50% of the portion of the average daily net assets exceeding
$1.0 billion. For the fiscal year ended August 31, 1996, the total fee paid by
the Fund to the Manager was $3,611,875 (based on average net assets of
approximately $660.4 million).
    
 
   
     The Management Agreement obligates the Trust on behalf of the Fund to pay
certain expenses incurred in its operations, including among other things, the
management fee, legal and audit fees, unaffiliated Trustees' 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. For the fiscal year ended August 31,
1996, the Fund reimbursed the Manager $118,709 for accounting services. For the
fiscal year ended August 31, 1996, the ratio of total expenses to average net
assets was .65% for Class A shares, 1.16% for Class B shares, 1.26% for Class C
shares and .75% 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.
 
                                       21
<PAGE>   24
 
     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 or 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 fiscal year
ended August 31, 1996, the Fund paid the Transfer Agent a total fee of $256,742
pursuant to the Transfer Agency Agreement for providing transfer agency
services. At November 30, 1996, the Fund had 935 Class A shareholder accounts,
10,043 Class B shareholder accounts, 309 Class C shareholder accounts and 3,857
Class D shareholder accounts. At this level of accounts, the annual fee payable
to the Transfer Agent would aggregate approximately $198,000 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 offers 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 PricingSM
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 order by the Distributor. As to purchase orders received by securities
dealers prior to the close of business on the New York Stock Exchange (the
"NYSE") (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 NYSE on that day, provided the Distributor in turn receives
the order from the securities dealer prior to 30 minutes after the close of
business on the NYSE, on that day. If the purchase orders are not
    
 
                                       22
<PAGE>   25
 
   
received by the Distributor prior to 30 minutes after the close of business on
the NYSE, such orders shall be deemed received on the next business day. Any
order may be rejected by the Distributor or the Fund. The Fund or the
Distributor may suspend the continuous offering of the Fund's shares to the
general public at any time in response to conditions in the securities markets
or otherwise and may thereafter resume such offering from time to time. 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 the "Merrill Lynch Select
Pricing(SM) System" on page 3.
    
 
   
     Each Class A, Class B, Class C and 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
CDSCs, distribution fees 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 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 "Initial Sales Charge
    Alternatives--Class A and Class D Shares--Eligible Class A Investors".
   
(3) Reduced for purchases of $25,000 or more and waived for purchases of Class A
    shares in connection with certain fee-based programs. 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. Such CDSC may be waived in connection with redemptions to fund
    participation in certain fee-based programs.
    
   
(4) The CDSC may be modified in connection with redemptions to fund
    participation in certain fee-based programs.
    
   
(5) The conversion period for dividend reinvestment shares and certain fee-based
    programs may be 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.
    
   
(6) The CDSC may be waived in connection with redemptions to fund participation
    in certain fee-based programs.
    
 
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 alternatives is the next determined net asset
value plus varying sales charges (i.e., sales loads), as set forth below.

** The initial sales charge may be waived on Class A and Class D purchases of
   $1,000,000 or more and on Class A purchases in connection with certain
   fee-based programs. If the sales charge is waived in connection with a
   purchase of $1,000,000 or more, such purchases may be subject to a CDSC of
   1.0% if the shares are redeemed within one year after purchase. Such CDSC may
   be waived in connection with redemptions to fund participation in certain
   fee-based programs. The charge will be assessed on an amount equal to the
   lesser of the proceeds of the redemption or the cost of the shares being

     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. For the
fiscal year ended August 31, 1996, the Fund sold 343,484 Class A shares for
aggregate net proceeds of $3,993,921. The gross sales charges for the sale of
Class A shares of the Fund for that year were $20,961, of which $2,185 and
$18,776 were received by the Distributor and Merrill Lynch, respectively. For
the fiscal year ended August 31, 1996, the Distributor received no CDSCs with
respect to redemption within one year after purchase of Class A shares purchased
subject to a front-end sales charge waiver. For the fiscal year ended August 31,
1996, the Fund sold 623,197 Class D shares for aggregate net proceeds of
$7,211,474. The gross sales charges for the sale of Class D shares of the Fund
for the year were $31,208, of which $2,960 and $28,248 were received by the
Distributor and Merrill Lynch, respectively. For the fiscal year ended August
31, 1996, 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 each 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 TMASM Managed Trusts to which Merrill
Lynch Trust Company provides discretionary trustee services, collective
investment trusts for which Merrill Lynch Trust Company serves as trustee and
purchases made in connection with certain fee-based programs. 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
registered investment companies, including the Trust. Certain persons who
acquired shares of certain MLAM-advised closed-end funds in their initial
offerings 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. In addition, 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. and, if certain
conditions set forth in the Statement of Additional Information are met, to
shareholders of Merrill Lynch Municipal Strategy Fund, Inc. and Merrill Lynch
High Income Municipal Bond Fund, Inc. who wish to reinvest the net proceeds from
a sale of certain of their shares of common stock pursuant to a tender offer
conducted by such funds in shares of the Fund and certain other MLAM-advised
mutual 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". See "Shareholder
Services -- Fee-Based Programs". Class A and Class D shares are offered at net
asset value to Employee Access Accounts(SM) available through qualified
employers which provide employer-sponsored retirement and savings plans that are
eligible to purchase such shares at net asset value. Class A shares are offered
at net asset value to shareholders of Merrill Lynch Senior Floating Rate Fund,
Inc. and, subject to certain conditions, Class A and Class D shares are offered
at net asset value to

shareholders of Merrill Lynch Municipal Strategy Fund, Inc. and Merrill Lynch
High Income Municipal Bond Fund, Inc., who wish to reinvest the net proceeds
from a sale of certain of their shares of common stock in shares of the Fund,
pursuant to tender offers conducted by those funds.
    
 
   
     Class D shares are offered at net asset value without 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.
    
 
   
     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 under "Distribution Plans". The proceeds from the ongoing
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."
    
 
   
     Proceeds from the CDSC 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 the
exchange will apply, and the holding period for the shares exchanged will be
tacked onto the holding period for the shares acquired.
    
 
                                       26
<PAGE>   29
 
   
     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. 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 August 31, 1996, the Distributor received CDSCs of
$427,650 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
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 or her first redemption of 50 shares (proceeds of $600), 10
shares will not be subject to the CDSC because of dividend reinvestment. With
respect to the remaining 40 shares, the CDSC is applied only to the original
cost of $10 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 rate in the third year after purchase).
    
 
   
     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. The terms of the CDSC may be modified in connection with
    
 
                                       27
<PAGE>   30
 
   
redemptions to fund participation in certain fee-based programs. See
"Shareholder Services -- Fee-Based Programs".
    
 
   
     Contingent Deferred Sales Charges--Class C Shares.  Class C shares which
are redeemed within one year after 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 fiscal year ended August 31,
1996, the Distributor received CDSCs of $4,398 with respect to redemptions of
Class C shares, all of which were paid to Merrill Lynch. No Class C CDSC will be
assessed in connection with redemptions to fund participation in certain
fee-based programs. See "Shareholder Services -- Fee-Based Programs".
    
 
   
     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 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.
 
     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
 
                                       28
<PAGE>   31
 
   
exchange will apply, and the holding period for the shares exchanged will be
tacked onto the holding period for the shares acquired.
    
 
   
     The Conversion Period may be modified for certain fee-based programs. See
"Shareholder Services -- Fee-Based Programs".
    
 
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 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. 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 rates 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 August 31, 1996, the Fund paid the Distributor
$2,723,756 pursuant to the Class B Distribution Plan (based on average net
assets subject to such Class B Distribution Plan of approximately $541.8
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. For the fiscal year ended August 31, 1996, the Fund paid the
Distributor $35,107 pursuant to the Class C Distribution Plan (based on average
net assets subject to such Class C Distribution Plan of approximately $5.8
million), all of which was paid to Merrill Lynch for providing account
maintenance and distribution-related activities and services in connection with
Class C shares. For the fiscal year ended August 31, 1996, the Fund paid the
Distributor $68,985 pursuant to the Class D Distribution Plan (based on average
net assets subject to such Class D Distribution Plan of approximately $68.6
million), all of which was paid to Merrill Lynch for providing account
maintenance activities in connection with Class D shares. At November 30, 1996,
the net assets of the Fund subject to the Class B Distribution Plan aggregated
approximately $460.4 million. At this asset level, the
    
 
                                       29
<PAGE>   32
 
   
annual fee payable pursuant to such Class B Distribution Plan would aggregate
approximately $2.3 million. At November 30, 1996, the net assets of the Fund
subject to the Class C Distribution Plan aggregated $9.4 million. At this asset
level, the annual fee payable pursuant to such Class C Distribution Plan would
aggregate approximately $56,000. At November 30, 1996, the net assets of the
Fund subject to the Class D Distribution Plan aggregated approximately $138.8
million. At this asset level, the annual fee payable pursuant to such Class D
Distribution Plan would aggregate approximately $139,000.
    
 
   
     Payments under the Distribution Plans 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
Directors 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, 1995, the fully
allocated accrual expenses incurred by the Distributor and Merrill Lynch for the
period since the commencement of operations of Class B shares exceeded fully
allocated accrual revenues by $5,694,000 (0.99% of Class B net assets at that
date). As of August 31, 1996, direct cash revenues for the period since the
commencement of operations of Class B shares exceeded direct cash expenses by
$21,546,289 (4.48% of Class B net assets at that date). Similar fully allocated
accrual data for Class C shares is not presented because such revenues and
expenses for the period from October 21, 1994 (commencement of operations) to
December 31, 1995 are de minimis. As of August 31, 1996, direct cash revenues
for the period since the commencement of operations of Class C shares exceeded
direct cash expenses by $14,011 (0.17% of Class C net assets at that date).
    
 
   
LIMITATIONS ON THE PAYMENT OF DEFERRED SALES CHARGES
    
 
   
     The maximum sales charge rule in the Conduct Rules 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 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
    
 
                                       30
<PAGE>   33
 
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 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 fees, the
distribution fees 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 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".
    
 
                              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 costs, 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 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 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 and 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.
    
 
                                       31
<PAGE>   34
 
   
     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 regular close of
business on the NYSE (generally, 4:00 P.M., New York time) on the day received
and is received by the Trust from such dealer not later than 30 minutes after
the close of business on the NYSE on the same day. Dealers have the
responsibility of submitting such repurchase requests to the Trust not later
than 30 minutes after the close of business on the NYSE 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 that do not have selected dealer agreements with the
Distributor, however, may impose a 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 to such
customers. Repurchases directly through the 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.
    
 
   
     Redemption payments will be made within seven days of the proper tender of
the certificates, if any, and stock power or letter requesting redemption, in
each instance with signatures guaranteed as noted above.
    
 
REINSTATEMENT PRIVILEGE--CLASS A AND CLASS D SHARES
 
   
     Shareholders who have redeemed their Class A or Class D shares have a
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. Alternatively, the
reinstatement privilege may be exercised through the investor's Merrill Lynch
Financial Consultant 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.
    
 
                              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
    
 
                                       32

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 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 gains distributions. The statements will also show any
other activity in the account since the preceding statement. Shareholders will
receive separate transaction confirmations for each purchase or sale transaction
other than automatic investment purchases and the reinvestments of ordinary
income dividends and long-term capital gains distributions. A shareholder may
make additions to his or her 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
    
 
   
     U.S. 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 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 or her 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 or her 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.
    
 
     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
 
                                       33
<PAGE>   36
 
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 for 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 of the exchanged
shares and a purchase of the acquired shares for Federal income tax purposes.
For further information, see "Shareholder Services-- Exchange Privilege" in the
Statement of Additional Information.
    
 
   
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 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 monthly.
Cash payments can also be directly deposited to the shareholders bank account.
No CDSC will be imposed on 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 or her Investment Account through automatic payment by check
or through automatic payment by direct deposit to his or her 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) or CBA(R) Systematic Redemption Program, subject to
certain conditions.
    
 
                                       34
<PAGE>   37
 
   
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. 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) accounts or in certain related accounts in amounts of
$100 or more through the CMA(R) or CBA(R) Automated Investment Program.
    
 
   
FEE-BASED PROGRAMS
    
 
   
     Certain Merrill Lynch fee-based programs, including pricing alternatives
for securities transactions (each referred to in this paragraph as a "Program"),
may permit the purchase of Class A shares at net asset value. Under specified
circumstances, participants in certain Programs may deposit other classes of
shares which will be exchanged for Class A shares. Initial or deferred sales
charges otherwise due in connection with such exchanges may be waived or
modified, as may the Conversion Period applicable to the deposited shares.
Termination of participation in a Program may result in the redemption of shares
held therein or the automatic exchange thereof to another class at net asset
value, which may be shares of a money market fund. In addition, upon termination
of participation in a Program, shares that have been held for less than
specified periods within such Program may be subject to a fee based upon the
current value of such shares. These Programs also generally prohibit such shares
from being transferred to another account at Merrill Lynch, to another
broker-dealer or to the Transfer Agent. Except in limited circumstances (which
may also involve an exchange as described above), such shares must be redeemed
and another class of shares purchased (which may involve the imposition of
initial or deferred sales charges and distribution and account maintenance fees)
in order for the investment not to be subject to Program fees. Additional
information regarding a specific Program (including charges and limitations on
transferability applicable to shares that may be held in such Program) is
available in such Program's client agreement and from Merrill Lynch Investor
Services at (800) MER-FUND (637-3863).
    
 
                             PORTFOLIO TRANSACTIONS
 
   
     Subject to the policies established by the Trustees of the Trust, the
Manager is primarily responsible for the execution of the Fund's 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
transaction involved, the firm's general execution and operational facilities,
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 or dealers to
execute portfolio transactions for the Fund. The portfolio securities of the
Fund are generally traded on a principal basis and do not normally 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
    
 
                                       35
<PAGE>   38
 
   
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 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 investment grade 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. An affiliated person of the
Trust may serve as its broker in over-the-counter transactions conducted by the
Fund on an agency basis only.
    
 
   
     Portfolio Turnover.  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. As a result of the investment
policies described herein, under certain market conditions the Fund's portfolio
turnover may be higher than that of other investment companies. 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 acquisition are one year or less are excluded. The
Fund will, however, monitor its trading so as to comply with the Federal income
tax requirement 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.
    
 
                            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 NYSE (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 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 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 at least annually. Capital gains
distributions will be reinvested automatically in shares unless the shareholder
elects to receive such distributions in cash.
    
 
                                       36
<PAGE>   39
 
     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 Code. If it
so qualifies, 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 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 and railroad retirement benefits
subject to Federal income taxes. The portion of such exempt-interest dividends
paid from interest received by the Fund from California Municipal Bonds also
will be exempt from California income taxes if, at the close of each quarter of
the Fund's taxable year, at least 50% of the value of the Fund's total assets
consists of California Municipal Bonds. The Fund intends to invest at least 50%
of its assets in California Municipal Bonds at all times. Shareholders subject
to income taxation by states other than California will realize a lower
after-tax rate of return than California shareholders since the dividends
distributed by the Fund will generally 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 Fund's distributions which constitutes
exempt-interest dividends and the portion which is exempt from California income
taxes. Interest on indebtedness incurred or continued to purchase or carry Fund
shares is not deductible for Federal or California personal 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 advisors before purchasing Fund shares.
    
 
   
     Exempt-interest dividends paid to a corporate shareholder subject to
California state franchise tax will not be exempt from California taxation.
    
 
   
     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 and California 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 and, for California income
tax purposes, are treated as capital gains which are taxed at ordinary income
tax rates. 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.
    
 
                                       37
<PAGE>   40
 
   
     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 disallowed to the extent of any exempt-interest dividends
received by the shareholder. In addition, any such loss that is not disallowed
under the rule stated above will be treated as long-term capital loss to the
extent of any capital gain 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 certain "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 (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 certain
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 "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 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 such shares, then the loss such shareholder can recognize on the
exchange will be reduced (or the gain increased) to the extent the sales charge
paid to the Fund 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").
    
 
                                       38
<PAGE>   41
 
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.
 
     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 applicable California income
tax laws. For the complete provisions, reference should be made to the pertinent
Code sections, Treasury regulations promulgated thereunder and California income
and corporate franchise tax laws. The Code and the Treasury regulations, as well
as the California tax laws, are subject to change by legislative, judicial or
administrative action either prospectively or retroactively.
    
 
   
     Shareholders are urged to consult their tax advisors regarding the
availability of any exemptions from state and local taxes (other than those
imposed by California) 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
 
                                       39
<PAGE>   42
 
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 purchases are subject to waiver of the CDSC in the case of Class
B and Class C 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 CDSC, 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 August 31,
1996 was 4.94% for Class A shares, 4.63% for Class B shares, 4.53% for Class C
shares and 4.84% for Class D shares and the tax-equivalent yield for the same
period (based on a Federal income tax rate of 28%) was 6.86% for Class A shares,
6.43% for Class B shares, 6.29% for Class C shares and 6.72% 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
by the Manager once daily, 15 minutes after the close of business on the NYSE
(generally, 4:00 P.M., New York time), on each day during which the NYSE 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
    
 
                                       40
<PAGE>   43
 
number of shares outstanding at such time, rounded to the nearest cent.
Expenses, including management fees and distribution fees, are accrued daily.
 
   
     The per share net asset value of the Class A shares generally will be
higher than the per share net asset value of shares of the other classes,
reflecting the daily expense accruals of the account maintenance, distribution
and higher transfer agency fees applicable with respect to 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 Class
D shares generally will be higher than the per share net asset value of Class B
and Class C shares, reflecting the daily expense accruals of the distribution
fees, higher account maintenance fees and higher transfer 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 March 20, 1985
under the laws of Massachusetts. The Trust is an open-end investment company
comprised of separate series ("Series"), each of which is a separate portfolio
offering shares to selected groups of purchasers. On December 22, 1987, the Fund
changed its name from "Merrill Lynch California Tax-Exempt Fund" to "Merrill
Lynch California 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 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 Trustees of the Trust may classify and
reclassify the shares of any Series into additional classes at a future date.
    
 
     Shareholders are entitled to one vote for each full share held and to
fractional votes for fractional shares held in the election of Trustees (to the
extent hereafter provided) and on other matters submitted to the vote of
shareholders. There normally will be no meetings 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
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
 
                                       41
<PAGE>   44
 
noted above, the 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:

                         ------------------------------
 
   
     The Declaration of Trust establishing the Trust, dated March 20, 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 of "Merrill Lynch California Municipal Series Trust"
refers to the Trustees under the Declaration collectively as Trustees, but not
as individuals or personally; and 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.

STATEMENT OF ADDITIONAL INFORMATION

                MERRILL LYNCH CALIFORNIA MUNICIPAL SERIES TRUST

                            ------------------------
 
   
     Merrill Lynch California Municipal Bond Fund (the "Fund") is a series of
Merrill Lynch California Municipal Series Trust (the "Trust"), an open-end
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 California income taxes as is consistent with prudent
investment management. The Fund seeks to achieve its objective, while providing
investors with the opportunity to invest primarily in a diversified portfolio of
long-term obligations issued by or on behalf of the State of California, 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 from Federal and California 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 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.
 
                            ------------------------
 
   
     This Statement of Additional Information of the Fund is not a prospectus

December 20, 1996 (the "Prospectus"), which has been filed with the Securities
and Exchange Commission (the "Commission") and can be obtained, without charge,

Statement of Additional Information has been incorporated by reference into the
Prospectus. Capitalized terms used but not defined herein have the same meanings

                       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 California income taxes as is
consistent with prudent investment management. The Fund seeks to achieve its
objective while providing investors with the opportunity to invest in a
portfolio of securities consisting primarily of long-term obligations issued by
or on behalf of the State of California, 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
California income taxes. Obligations exempt from Federal income taxes are
referred to herein as "Municipal Bonds" and obligations exempt from both Federal
and California income taxes are referred to as "California Municipal Bonds".
Unless otherwise indicated, references to Municipal Bonds shall be deemed to
include California 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 California 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. At least 80% of 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, Inc. ("Moody's") (currently Aaa,
Aa, A and Baa), Standard & Poor's Ratings Services ("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 will possess
creditworthiness comparable, in the opinion of the manager of the Fund, Fund
Asset Management, L.P. (the "Manager"), to other obligations in which the Fund
may invest.
    
 
   
     The Fund ordinarily does not intend to realize investment income not exempt
from Federal and California income taxes. However, to the extent that suitable
California 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 California income taxes. 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 also
could include trust certificates or other derivative instruments evidencing
interests in one or more long-term municipal securities.
    
 
   
     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 California Municipal Bonds. For temporary 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, together
    
 
                                        2
<PAGE>   55
 
   
with such other instruments as are not exempt from California taxation, shall
not exceed 20% of the Fund's total assets. The Fund at all times will have at
least 80% of its total 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 total assets in Temporary Investments for defensive purposes, when, in the
judgment of the Manager, market conditions warrant. The investment objectives of
the Fund 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 voting
securities, as defined in the 1940 Act, 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 on 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 obligations 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. 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, 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, to hedge other portfolio positions or to vary the degree of investment
leverage relatively efficiently under different market conditions.
    
 
                                        3

     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 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 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
generally 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 or obligors 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 or
obligors of high yield securities may be more likely to experience financial
stress, especially if such issuers or obligors are highly leveraged. During such
periods, 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.
 
     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
 
                                        4
<PAGE>   57
 
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 are generally 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 outstanding obligations and obtaining funds for general operating
expenses and loans to other public institutions and facilities. In addition,
certain types of industrial development bonds or private activity bonds are
issued by or on behalf of public authorities to finance various privately owned
or operated facilities. Such obligations are included within the term California
Municipal Bonds if the interest paid thereon is, in the opinion of bond counsel,
excluded from gross income for Federal and California income tax purposes and
such obligations are issued by the State of California, its political
subdivisions, agencies and instrumentalities or are obligations of other
qualifying issuers. Other types of industrial development bonds or private
activity bonds, the proceeds of which are used for the construction, equipment
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. In the case of certain
community facilities district special tax, tax increment (or tax allocation) and
assessment bonds, the payment of the special tax, tax increment and assessments
may be secured solely by remedies
    
 
                                        5
<PAGE>   58
 
against the land (such as by foreclosure) and not against the individual
property owner, which could be time-consuming and costly.
 
   
     The two principal classifications of Municipal Bonds are "general
obligation" bonds 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 repayment of principal and the payment of 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 payments from the user of the facility
being financed. IDBs and, in the case of bonds issued after August 15, 1986,
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 repayment of the principal of and the payment of the interest on
such IDBs and private activity 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. 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.
    
 
   
     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. 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 the guidelines
which have been adopted by the Trustees and subject to the supervision of the
Board of Trustees, determines to be liquid. The Manager will deem lease
obligations 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 the issuer, 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 securities 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
    
 
                                        6
<PAGE>   59
 
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 and to general equitable principles, which may limit the
enforcement of certain remedies.
 
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 Public Securities
Association Index 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 or 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.
 
     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
period exceeding seven days will therefore be subject to the Fund's restriction
 
                                        7
<PAGE>   60
 
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 will be ultimately responsible for
such determination.
 
   
     The Trust has established the following standards with respect to money
market securities and VRDOs 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, 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
(the "FDIC"), except that up to 10% of the Fund's 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 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 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 more than seven
days if such investments, together with other illiquid investments, would exceed
15% of the Fund's total assets.
    
 
                                        8
<PAGE>   61
 
   
     In general, for Federal 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 (or 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 financial 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 Financial Futures Contracts.  A financial futures contract
is an agreement between two parties to buy and sell a security, or in the case
of an index-based financial futures contract, to make and accept a cash
settlement for a set price on a future date. A majority of transactions in
financial 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. Financial futures
contracts have been designed by boards of trade which have been designated
"contracts markets" by the Commodity Futures Trading Commission (the "CFTC").
 
   
     The purchase or sale of a financial 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 financial 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 financial futures
contract fluctuates making the long and short positions in the financial futures
contract more or less valuable, a process known as "mark to the market". At any
time prior to the settlement date of the financial futures contract, the
position may be closed out by taking an opposite position which will operate to
terminate the position in the financial 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 purchaser 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 (the "CBT") and The
Bond Buyer (the "Municipal Bond Index"). The Municipal Bond Index is comprised
of 40 tax-exempt municipal revenue bonds and general obligation 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
 
                                        9
<PAGE>   62
 
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 financial futures contract is traded only on the
CBT. Like other contract markets, the CBT assures performance under financial
futures contracts through a clearing corporation, a non-profit organization
managed by the exchange membership which is also 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, U.S. Treasury notes, Government National Mortgage
Association ("GNMA") Certificates and three-month U.S. Treasury bills. The Fund
may purchase and write call and put options on financial 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 financial futures contracts transactions such as financial 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 financial 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 financial 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 financial futures
positions, commissions on financial 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 financial 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
financial futures contracts as a hedge against any increase in the cost of such
Municipal Bonds resulting from a decrease in interest rates or otherwise, that
may occur before such purchases can be effected. Subject to the degree of
correlation between the Municipal Bonds and the financial 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
 
                                       10
<PAGE>   63
 
made, an equivalent amount of financial 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. 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 financial 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 a put option on a
futures contract is analogous to the purchase of a protective put option 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 financial futures contract may be a "senior security" under the 1940 Act.
    
 
     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
financial 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
 
                                       11
<PAGE>   64
 
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 liquid 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 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 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 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.
 
                                       12
<PAGE>   65
 
   
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 financial futures contracts can
result in substantial unrealized gains or losses. Because the Fund will engage
in the purchase and sale of financial 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 fully reflected in the value of the
option purchased.
    
 
   
     Municipal Bond Index futures contracts were approved for trading in 1986.
Trading in such financial 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. Make any investment inconsistent with the Fund's classification as
     a diversified company under the Investment Company Act.
 
          2. 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.
 
          3. Make investments for the purpose of exercising control or
     management.
 
          4. 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.
 
          5. 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
 
                                       13
<PAGE>   66
 
     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.
 
          6. Issue senior securities to the extent such issuance would violate
     applicable law.
 
   
          7. 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 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.
    
 
          8. 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.
 
   
          9. 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 that cannot be readily resold because of legal
     or contractual restrictions or that 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 Trust has otherwise
     determined to be liquid pursuant to applicable law.
    
 
   
          d. Notwithstanding fundamental investment restriction (7) 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
 
                                       14
<PAGE>   67
 
   
(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-governmental
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 Fund is prohibited from
engaging in certain transactions involving such firm or its affiliates except
for brokerage transactions permitted under the 1940 Act involving only usual and
customary commissions or transactions pursuant to an exemptive order under the
1940 Act. Included among such restricted transactions will be purchases from or
sales to Merrill Lynch of securities in transactions in which it acts as
principal. See "Portfolio Transactions". An exemptive order has been obtained
which permits the Trust to effect principal transactions with Merrill Lynch in
high quality, short-term, tax-exempt securities subject to conditions set forth
in such order.

COMPENSATION OF TRUSTEES
 
   
     The Trust pays each Trustee not affiliated with the Manager (each a
"non-affiliated Trustee") a fee of $5,000 per year plus $500 per meeting
attended. The Trust also compensates members of its Audit and Nominating
Committee (the "Committee"), which consists of all of the non-affiliated
Trustees, a fee of $1,000 per year plus $250 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 August 31, 1996, fees and expenses paid to
non-affiliated Trustees which were allocated to the Fund aggregated $40,129.
    
 
   
     The following table sets forth for the fiscal year ended August 31, 1996,
compensation paid by the Fund to the non-affiliated Trustees and, for the
calendar year ended December 31, 1995, the aggregate compensation paid by all
registered investment companies (including the Trust) advised by FAM and its
affiliate, MLAM ("FAM/MLAM Advised Funds") to the non-affiliated Trustees:

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 agreements 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 purchases or sales of securities for the Fund or
other funds for which they act as manager or for their advisory clients and such
sales and purchases 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
    
 
                                       17
<PAGE>   70
 
   
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 at the annual rate of 0.55% of the
average daily net assets of the Fund. As discussed in the Prospectus, effective
December 23, 1987, the Manager has voluntarily agreed to waive the amount of
compensation set forth in the Management Agreement and instead has agreed 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 portion of the average
daily net assets not exceeding $500 million; 0.525% of the portion of the
average daily net assets exceeding $500 million but not exceeding $1.0 billion
and 0.50% of the portion of the average daily net assets exceeding $1.0 billion.
For the fiscal years ended August 31, 1994, 1995 and 1996, the total advisory
fees paid by the Fund to the Manager aggregated $4,567,938, $3,828,093 and
$3,611,875, respectively.
    
 
   
     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 fees 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 a
portion of the Trust's general administrative expenses will be allocated on the
basis of the asset size of the respective series of the Trust ("Series").
Expenses that will be borne directly by the Series include 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 will be 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 Trust by the Manager and the Trust reimburses the
Manager for its costs in connection with such services. For the fiscal years
ended August 31, 1994, 1995 and 1996, the Fund reimbursed the Manager $101,105,
$64,518 and $118,709, respectively for such 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
and Class C shares will be financed by the Fund pursuant to the Distribution
Plans in compliance with Rule 12b-1 under the 1940 Act. See "Purchase of
Shares--Deferred Sales Charge Alternatives--Class B and Class C
Shares--Distribution Plans".
    
 
     The Manager is a limited partnership, the partners of which are ML & Co.

because of their ownership of its voting securities or their power to exercise a
controlling influence over its management or policies.
 
     Duration and Termination.  Unless earlier terminated as described below,
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 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. 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
registered investment companies advised by MLAM or its affiliate, the Manager.
Funds advised by MLAM or the Manager which utilize the Merrill Lynch Select
Pricing(SM) System are referred to herein as "MLAM-advised mutual funds".
    
 
     The Fund has entered into 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 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 fiscal year
ended August 31, 1994 were $132,664, of which the Distributor received $13,053
and Merrill Lynch received $119,611. The gross sales charges for the sale of
Class A shares for the fiscal year ended August 31, 1995 were $30,995, of which
the Distributor received $2,220 and Merrill Lynch received $28,775. The gross
sales charges for the sale of Class

A shares for the fiscal year ended August 31, 1996 were $20,961, of which the
Distributor received $2,185 and Merrill Lynch received $18,776. The gross sales
charges for the sale of Class D shares for the period October 21, 1994
(commencement of operations) to August 31, 1995, were $22,241, of which the
Distributor received $1,704 and Merrill Lynch received $20,537. The gross sales
charges for the sale of Class D shares for the fiscal year ended August 31, 1996
were $31,208, of which the Distributor received $2,960 and Merrill Lynch
received $28,284. For the fiscal years ended August 31, 1994, 1995 and 1996 the
Distributor received no CDSCs with respect to redemptions within one year after
purchase of Class A shares purchased subject to a front-end sales charge waiver.
For the period October 21, 1994 (commencement of operations) to August 31, 1995
and for the fiscal year ended August 31, 1996, the Distributor received no CDSCs
with respect to redemptions within one year after purchase of Class D shares
purchased subject to a front-end sales charge waiver.
    
 
     The term "purchase", as used in the Prospectus and in 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 or her spouse and their children under
the age of 21 years purchasing shares for his or her 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.
    
 
   
     Shareholders of certain MLAM-advised continuously offered closed-end funds
may reinvest at net asset value the net proceeds from a sale of certain shares
of common stock of such funds in shares of the Fund. Upon exercise of this
investment option, shareholders of Merrill Lynch Senior Floating Rate Fund, Inc.
will receive Class A shares of the Fund and shareholders of Merrill Lynch
Municipal Strategy Fund, Inc. and Merrill Lynch High Income Municipal Bond Fund,
Inc. will receive Class D shares of the Fund, except that
    
 
                                       20
<PAGE>   73
 
   
shareholders already owning Class A shares will be eligible to purchase
additional Class A shares pursuant to this option, if such additional Class A
shares will be held in the same account as the existing Class A shares and the
other requirements pertaining to the reinvestment privilege are met. In order to
exercise this investment option, a shareholder of one of the above-referenced
continuously offered closed-end funds (an "eligible fund") must sell his or her
shares of common stock of the eligible fund (the "eligible shares") back to the
eligible fund in connection with a tender offer conducted by the eligible fund
and reinvest the proceeds immediately in the designated class of shares of the
Fund. This investment option is available only with respect to eligible shares
as to which no Early Withdrawal Charge or CDSC (each as defined in the eligible
fund's prospectus) is applicable. Purchase orders from eligible fund
shareholders wishing to exercise this investment option will be accepted only on
the day that the related tender offer terminates and will be effected at the net
asset value of the designated class of the Fund on such day.
    
 
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 record-keeping 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 at least 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)
    
 
                                       21
<PAGE>   74
 
   
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 of 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 charge on any
previous purchase. The value of any shares redeemed or otherwise 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 AccountsSM available through qualified 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 to TMA(SM) Managed
Trusts to which Merrill Lynch Trust Company provides discretionary trustee
services at net asset value.
    
 
   
     Purchase Privilege 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 a 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 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 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 no
    
 
                                       22
<PAGE>   75
 
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 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 required 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).
    
 
   
     Reductions in or exemptions from the imposition of a sales load are due to
the nature of the investors and/or the reduced sales efforts that will be needed
in obtaining such investments.
    
 
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 the 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 such 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 of 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
such
    
 
                                       23
<PAGE>   76
 
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 Conduct Rules of the National
Association of Securities Dealers, Inc. (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 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 fees 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 August 31,
1996 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 Class B shares, the Distributor's voluntary maximum.

    will reach either the voluntary maximum (with respect to Class B shares) or
    the NASD maximum (with respect to Class B and Class C shares).
 
                              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 ("NYSE") is restricted as determined by the Commission or
the NYSE 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 redemptions 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
August 31, 1994, 1995 and 1996 the Distributor received CDSCs of $704,845,
$866,830 and $427,650, respectively, with respect to redemptions of Class B
shares, all of which were paid to Merrill Lynch. For the period October 21, 1994
(commencement of operations) to August 31, 1995, and for the fiscal year ended
August 31, 1996 the Distributor received CDSCs of $8,242 and $4,398,
respectively, with respect to redemptions of Class C shares, all of which were
paid to Merrill Lynch.
    
 
                             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 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. During the fiscal year ended August 31, 1994, the Fund engaged in no
transactions pursuant to such order. During the fiscal year ended August 31,
1995, the Fund engaged in sixty transactions pursuant to such order for an
aggregate market value of approximately $138.3 million. For the fiscal year
ended August 31, 1996, the Fund engaged in six transactions pursuant to such
order for an aggregate market value of approximately $9.9 million. The Trust has
    
 
                                       25
<PAGE>   78
 
applied for an exemptive order, subject to certain conditions, permitting the
Trust to, among other things, (i) purchase investment grade tax-exempt
securities from Merrill Lynch when Merrill Lynch is a member of an underwriting
syndicate for such securities and (ii) purchase tax-exempt securities from and
sell tax-exempt securities to Merrill Lynch in secondary market transactions.
Affiliated persons of the Fund may serve as its broker 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.
 
   
     Under the 1940 Act, the Fund may not purchase securities during the
existence of 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. As
indicated above, the Trust has applied for a conditional exemption from these
transactions.
    
 
     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 expense 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 Conduct Rules 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. 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 acquisition are one
year or less are excluded. The portfolio turnover rates for the fiscal years
ended August 31, 1995 and 1996 were 53.40% and 53.79%, 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
 
                                       26
<PAGE>   79
 
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
by the Manager once daily, Monday through Friday, as of 15 minutes after the
close of business on the NYSE (generally, 4:00 P.M. New York time), on each day
during which the NYSE is open for trading. The NYSE 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 any account maintenance and/or distribution fees, are accrued
daily. The per share net asset value of Class B, Class C and Class D shares
generally will be lower than the per share net asset value of Class A shares,
reflecting the daily expense accruals of the account maintenance, distribution
and higher transfer agency fees applicable with respect to Class B and Class C
shares and the daily expense accruals of the account maintenance fees applicable
with respect to Class D shares. In addition, the per share net asset value of
Class B and Class C shares generally will be lower than the per share net asset
value of Class D shares, reflecting the daily expense accruals of the
distribution fees, higher account maintenance fees and higher transfer agency
fees applicable with respect to 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 differential 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 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.
 
                                       27
<PAGE>   80
 
INVESTMENT ACCOUNT
 
   
     Each shareholder whose account is maintained at the Transfer Agent has an
Investment Account and will receive, at least quarterly, statements from the
Transfer Agent. The statements will serve as transaction confirmations for
automatic investment purchases and the reinvestment of ordinary income
dividends, and long-term capital gain distributions. These statements also will
show any other activity in the account since the preceding statement.
Shareholders 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 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. 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 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 dealer.
Voluntary accumulation can also 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. 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) accounts or in certain related accounts in
amounts of $100 or more through the CMA(R) or 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
automatically reinvested 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
    
 
                                       28
<PAGE>   81
 
   
their income dividends or capital gains distributions, or both, in cash, in
which event payment will be mailed on or about the payment date.
    
 
     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, those 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 or her 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 NYSE (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 NYSE 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 Fund, 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 Fund 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) or
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 three 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 Systematic Redemption
    
 
                                       29
<PAGE>   82
 
   
Program is not available if Fund shares are being purchased within the account
pursuant to the Automatic Investment Program. For more information on the CMA(R)
or CBA(R) Systematic Redemption Program, eligible shareholders should contact
their Merrill Lynch Financial Consultant.
    
 
EXCHANGE PRIVILEGE
 
   
     Shareholders of each class of shares of the Fund have an exchange privilege
with certain other MLAM-advised mutual funds. Under the Merrill Lynch SelectSM
Pricing 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 or her 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, but 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
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 for the newly acquired shares of the other fund as more fully described
below. Class A, Class B, Class C and Class D shares also are exchangeable for
shares of certain MLAM-advised money market funds as follows: Class A shares may
be exchanged for shares of Merrill Lynch Ready Assets Trust, Merrill Lynch
Retirement Reserves Money Fund (available only for exchanges within certain
retirement plans), Merrill Lynch U.S.A. Government Reserves and Merrill Lynch
U.S. Treasury Money Fund; Class B, Class C and Class D shares may be exchanged
for shares of Merrill Lynch Government Fund, Merrill Lynch Institutional Fund,
Merrill Lynch Institutional Tax-Exempt Fund and Merrill Lynch Treasury Fund.
Shares with a net asset value of at least $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 or 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 certain money market
funds without a sales charge.
    
 
                                       30
<PAGE>   83
 
   
     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 CDSC 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
CDSC 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 deferred sales charge 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
shares, the holding period for the outstanding Class B 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 Special Value Fund Class B shares for more than five years.
    
 
   
     Shareholders also may exchange shares of the Fund into shares of certain
money market funds 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, toward 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, 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 newly-acquired 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 cash. 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 would not incur a CDSC.
    
 
   
     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, a shareholder should contact his or her
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 in accordance with the rules of the
Commission. The Fund reserves the right to limit the number of times an investor
may exercise the
    
 
                                       31
<PAGE>   84
 
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, 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.
    
 
     As discussed in the Fund's Prospectus, the Trust has established another
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
will be determined 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 its taxable year, at least 50% of the value of the Fund's 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 rule permitting the issuance and sale
of multiple classes of shares) that is based on the gross income allocable to
the 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
    
 
                                       32
<PAGE>   85
 
   
paying exempt-interest dividends, such as the Fund, will not be deductible by
the investor for Federal or California 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 California Municipal Bonds will be exempt from
California income taxes 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 California
Municipal Bonds. The Fund intends to invest at least 50% of its assets in
California Municipal Bonds at all times. Shareholders subject to income taxation
in states other than California will realize a lower after tax rate of return
than California shareholders since the dividends distributed by the Fund will
generally not be exempt, to any significant degree, from 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 California income taxes. The Fund will allocate
exempt-interest dividends among the Class A, Class B, Class C and Class D
shareholders for California income tax purposes based on a method similar to
that described above for Federal income tax purposes.
    
 
   
     Distributions from investment income and capital gains, including
exempt-interest dividends, may be subject to the California state franchise tax
if received by a corporation subject to such tax, and may be subject to state
taxes in states other than California and to local taxes. Accordingly, investors
in the Fund including, in particular, corporate investors which may be subject
to the California corporate franchise tax should consult their tax advisers with
respect to the application of such taxes to Fund dividends and as to their
California tax situation in general.
    
 
     To the extent 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 and, for California income tax purposes, will
be treated as capital gains which are taxed at ordinary income tax rates.
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 disallowed to the extent of any exempt-interest dividends
received by the shareholder. In addition, any such loss that is not disallowed
under the rule stated above will be treated as long-term capital loss to the
extent of any capital gain 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
    
 
                                       33
<PAGE>   86
 
such dividend will be treated for tax purposes as being paid by the Fund and
received by its shareholders on December 31, of such year.
 
   
     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 certain 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 are a tax preference item 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.
    
 
   
     The Fund may invest in high yield securities as previously described.
Furthermore, the Fund may also invest in instruments the return on which
includes nontraditional features such as indexed principal or interest payments
("nontraditional instruments"). These instruments may be subject to special tax
rules under which the Fund may be required to accrue and distribute income
before amounts due under the obligations are paid. In addition, it is possible
that all or a portion of the interest payments on such high yield securities
and/or nontraditional instruments could be recharacterized as taxable ordinary
income.
    
 
   
     No gain or loss will be recognized 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 such shares, then the loss such 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% United States 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 advisers concerning the applicability of the United States withholding tax.
 
                                       34
<PAGE>   87
 
     Under certain provisions of the Code, 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.
 
     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 previously imposed 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 has
expired for tax years beginning after December 31, 1995, but may be reinstated
in the future. The Environmental Tax was imposed even if the corporation was not
required to pay an alternative minimum tax because the corporation's regular
income tax liability exceeded its minimum tax liability. The Code provides,
however, that a RIC such as the Fund would not be subject to the Environmental
Tax. However, exempt-interest dividends paid by the Fund that create alternative
minimum taxable income for corporate shareholders under the Code (as described
above) could subject corporate shareholders of the Fund to the Environmental
Tax.
    
 
TAX TREATMENT OF FUTURES AND OPTION TRANSACTIONS
 
     The Fund may write, 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 fair 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 sales of securities and 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 sales of
securities and 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,
 
                                       35
<PAGE>   88
 
   
the Fund may be restricted in effecting closing transactions within three months
after entering into an option or financial futures contract.
    
 
     The foregoing is a general and abbreviated summary of the applicable
provisions of the Code, Treasury regulations and applicable California 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 California tax laws. The Code and the Treasury regulations, as
well as the California tax laws, are subject to change by legislative, judicial
or administrative action either prospectively or retroactively.
 
   
     Shareholders are urged to consult their tax advisors regarding the
availability of any exemptions from state or local taxes (other than those
imposed by California) 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 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 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 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 CDSC and
therefore may reflect greater total return since, due to the reduced sales
charges 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 and Merrill
Lynch California Insured 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 $.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 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 respective Series and in 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 Class D
shares are borne solely by such class. There will normally be no meetings 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 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
 
                                       38
<PAGE>   91
 
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. 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.

                                   APPENDIX I
 
                  ECONOMIC AND OTHER CONDITIONS IN CALIFORNIA
 
   
     The following information is a brief summary of factors affecting the
economy of the State 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
state issuers; however, it has not been updated nor will it be updated during
the year. The Trust has not independently verified the information.
    
 
ECONOMIC CONDITIONS
 
   
     The economy of the State of California (sometimes referred to herein as the
"State") is the largest among the 50 states and one of the largest in the world.
This diversified economy has major components in agriculture, manufacturing,
high technology, trade, entertainment, tourism, construction and services. Total
State gross domestic product of about $890 billion in 1995 was larger than all
but six nations in the world.
    
 
   
     California's July 1, 1994 population of over 32 million represented over 12
percent of the total United States population. The official 1990 Census
population was 29,760,021 as of April 1, 1990, which represented an increase of
over 6 million persons, or 26 percent, during the decade of the 1980's. As of
the April 1, 1990 Census, the median age of California's population was 31.5
years, younger than the 1990 U.S. median of 32.9 years.
    
 
   
     California's population is concentrated in metropolitan areas. As of the
April 1, 1990 Census, 96 percent resided in the 23 Metropolitan Statistical
Areas in the State. Overall, California's population per square mile was 191 in
1990. As of July 1, 1995, the 5-county Los Angeles area accounted for 49
percent, with 15.6 million residents. The 10-county San Francisco Bay Area
represented 21 percent, with a population of 6.6 million.
    
 
   
     After suffering through a severe recession, California's economy has been
on a steady recovery since the start of 1994. Employment grew by over 500,000 in
1994 and 1995, and the pre-recession level of total employment is expected to be
matched in 1996. The strongest growth has been in export-related industries,
business services, electronics, entertainment and tourism, all of which have
offset the recession-related losses which were heaviest in aerospace and
defense-related industries (which accounted for two-thirds of the job losses),
finance and insurance. Residential housing construction, with new permits for
under 100,000 annual new units issued in 1994 and 1995, is weaker than in
previous recoveries, but has been growing slowly since 1993.
    
 
   
     The State.  In the years following enactment of the Federal Tax Reform Act
of 1986, and conforming changes to the State's tax laws, taxpayer behavior
became much more difficult to predict, and the State experienced a series of
fiscal years in which revenue came in significantly higher or lower than
original estimates. The 1989-90 Fiscal Year ended with revenues below estimates,
so that the State's budget reserve (the Special Fund for Economic Uncertainties
or "SFEU") was fully depleted by June 30, 1990. This date essentially coincided
with the start of the current recession, which severely affected State General
Fund revenues and increased expenditures above initial budget appropriations due
to greater health and welfare costs. The State's budget problems in recent years
have also been caused by a structural imbalance which has been identified by the
current and previous Administrations. The largest General Fund Program -- K-14
education, health, welfare and corrections -- was increasing faster than the
revenue base, driven by the State's
    
 
                                       41
<PAGE>   94
 
   
rapid population growth. These pressures will continue as population trends
maintain strong demand for health and welfare services, as the school-age
population continues to grow and as the State's corrections program responds to
a "Three Strikes" law enacted in 1994, which requires mandatory life prison
terms for certain third-time felony offenders.
    
 
   
     Prior Years.  As a result of these factors and others, from the late 1980s
until 1992-93, the State had a period of budget imbalance. During this period,
expenditures exceeded revenues in four out of six years, and the State
accumulated and sustained a budget deficit in the SFEU approaching $2.8 billion
at its peak at June 30, 1993. Starting in the 1990-91 Fiscal Year and for each
fiscal year thereafter, each budget required multi-billion dollar actions to
bring projected revenues and expenditures into balance and to close large
"budget gaps" which were identified. Despite budget actions by the Legislature,
the effects of the recession led to large, unanticipated deficits in the budget
reserve, the SFEU, as compared to projected positive balances. By the 1993-94
Fiscal Year, the accumulated deficit was so large that it was impractical to
budget to retire it in one year, so a two-year program was implemented, using
the issuance of revenue anticipation warrants to carry a portion of the deficit
over the end of the fiscal year. When the economy failed to recover sufficiently
in 1993-94, a second two-year plan was implemented in 1994-95.
    
 
   
     Another consequence of the accumulated budget deficits, together with other
factors such as disbursement of funds to local school districts "borrower" from
future fiscal years and hence not shown in the annual budget, was to
significantly reduce the State's cash resources available to pay its ongoing
obligations. The State's cash condition became so serious in late Spring of 1992
that the State Controller was required to issue revenue anticipation warrants
maturing in the following fiscal year in order to pay the State's continuing
obligations. The State was forced to rely increasingly on external debt markets
to meet its cash needs, as a succession of notes and warrants were issued in the
period from June 1992 to July 1994, often needed to pay previously maturing
notes or warrants. These borrowings were used also in part to spread out the
repayment of the accumulated budget deficit over the end of the fiscal year.
    
 
   
     The 1994-95 Fiscal Year represented the fourth consecutive year that the
Governor and the Legislature were faced with a very difficult budget environment
to produce a balanced budget. Many program cuts and budgetary adjustments had
already been made in the last three years. The Governor's budget proposal, as
updated in May and June, 1994, recognized that the accumulated deficit could not
be repaid in one year and proposed a two-year solution.
    
 
   
     Pursuant to the Budget Adjustment Law (the "Law"), the State Controller was
required to make a report by November 15, 1994 on whether the projected cash
resources for the General Fund as of June 30, 1995 would decrease more than $430
million from the amount projected by the State in its Official Statement in July
1994 for the sale of $4,000,000,000 of revenue anticipation warrants. On
November 15, 1994, the State Controller issued the report on the State's cash
position required by the Law. The report indicated that the cash position of the
General Fund on June 30, 1995 would be $581 million better than was estimated in
the July 1994 cash flow projections and therefore, no budget adjustment
procedures would be invoked for the 1994-95 Fiscal Year.
    
 
   
     On October 15, 1995, when the State Controller, in conjunction with the
Legislative Analyst's Office, reviewed the estimated cash condition of the
General Fund for the 1995-96 Fiscal Year, the State Controller estimated that
the General Fund would have internal cash resources on June 30, 1996 (i.e.,
external borrowing would not be needed to pay all obligations due). If a cash
shortfall had been identified by the State Controller,
    
 
                                       42
<PAGE>   95
 
   
the State Legislature would have been required to enact legislation providing
for sufficient General Fund expenditure reductions, revenue increases, or both.
    
 
   
     1995-96.  On January 10, 1995, the Governor presented his 1995-96 Fiscal
Year budget proposal (the "Proposed Budget"). Two of the principal features of
the Proposed Budget were a phased 15% cut in personal income and corporate taxes
and a further expansion of the "realignment" process to transfer more
responsibility and funding sources for certain health and welfare programs to
local governments. Neither of these proposals was approved by the Legislature.
As a result of the improving economy, with resulting improved revenue and
caseload estimates, the State entered the 1995-96 budget negotiations with the
smallest nominal "budget gap" to be enclosed in many years.
    
 
   
     The 1995-96 Budget Act was signed by the Governor on August 3, 1995. The
Budget Act projects General Fund revenues and transfers of $44.1 billion, a 3.5
percent increase from the prior year. Expenditures are budgeted at $43.4
billion, a 4 percent increase. The Department of Finance projects that, after
repaying the last of the carryover budget deficit, there will be a positive
balance of $28 million in the budget reserve, the SFEU, at June 30, 1996. The
Budget Act also projects Special Fund revenues of $12.7 billion and appropriates
Special Fund expenditures of $13.4 billion.
    
 
   
     1996-1997.  The following are principal features of the 1996-97 Budget Act:
    
 
   
     1. Proposition 98 funding for schools and community college districts
increased by almost $1.6 billion (General Fund) and $1.65 billion total above
revised 1995-96 levels. Almost half of this money was budgeted to fund
class-size reductions in kindergarten and grades 1-3. Also, for the second year
in a row, the full cost of living allowance (3.2 percent) was funded. The
Proposition 98 increases have brought K-12 expenditures to almost $4,800 per
pupil (also called per ADA, or Average Daily Attendance), an almost 15% increase
over the level prevailing during the recession years. Community colleges will
receive an increase in funding of $157 million for 1996-97 out of this $1.6
billion total.
    
 
   
     Because of the higher than projected revenues in 1995-96, an additional
$1.1 billion ($190 per K-12 ADA and $145 million for community colleges) was
appropriated and retroactively applied towards the 1995-96 Proposition 98
guarantee, bringing K-12 expenditures in that year to over $4,600 per ADA. These
new funds were appropriated for a variety of purposes, including block grants,
allocations for each school site, facilities for class size reduction, and a
reading initiative. Similar retroactive increases totaling $230 million, based
on final figures on revenues and State population growth, were made to the
1991-92 and the 1994-95 Proposition 98 guarantees, most of which was allocated
to each school site.
    
 
   
     2. The Budget Act assumed savings of approximately $660 million in health
and welfare costs which required changes in federal law, including federal
welfare reform. The Budget Act further assumed federal law changes in August
1996 which would allow welfare cash grant levels to be reduced by October 1,
1996. These cuts totaled approximately $163 million of the anticipated $660
million savings.
    
 
   
     3. A 4.9 percent increase in funding for the University of California ($130
million General Fund) and the California State University system ($101 million
General Fund), with no increases in student fees, maintaining the second year of
the Governor's four-year "Compact" with the State's higher education units.
    
 
   
     4. The Budget Act assumed the federal government will provide approximately
$700 million in new aid for incarceration and health care costs of illegal
immigrants. These funds reduce appropriations in these categories that would
otherwise have to be paid from the General Fund. (For purposes of cash flow
    
 
                                       43
<PAGE>   96
 
   
projections, the Department of Finance expects $540 million of this amount to be
received during the 1996-97 fiscal year.)
    
 
   
     5. General Fund support for the Department of Corrections was increased by
about 7 percent over the prior year, reflecting estimates of increased prison
population.
    
 
   
     6. With respect to aid to local governments, the principal new programs
included in the Budget Act are $100 million in grants to cities and counties for
law enforcement purposes, and budgeted $50 million for competitive grants to
local governments for programs to combat juvenile crime.
    
 
   
     The Budget Act did not contain any tax increases. As noted, there was a
reduction in corporate taxes. In addition, the Legislature approved another
one-year suspension of the Renters Tax Credit, saving $520 million in
expenditures.
    
 
   
     Federal Welfare Reform.  Following enactment of the 1996-97 Budget Act,
Congress passed and the President signed (on August 22, 1996) the Personal
Responsibility and Work Opportunity Act of 1996 (P.L. 104-193, the "Law") making
a fundamental reform of the current welfare system. Among many provisions, the
Law includes: (i) conversion of Aid to Families with Dependent Children from an
entitlement program to a block grant titled Temporary Assistance for Needy
Families (TANF), with lifetime time limits on TANF recipients, work requirements
and other changes; (ii) provisions denying certain federal welfare and public
benefits to legal noncitizens, allowing states to elect to deny additional
benefits (including TANF) to legal noncitizens, and generally denying almost all
benefits to illegal immigrants; and (iii) changes in the Food Stamp program,
including reducing maximum benefits and imposing work requirements.
    
 
   
     The Law requires states to implement the new TANF program not later than
July 1, 1997 and provides California approximately $3.7 billion in block grant
funds for FY 1996-97 for the provisions of the Law. States are allowed to
implement TANF as soon as possible and will receive a prorated block grant
effective the date of application. The California State Plan is to be submitted
in time to allow grant reductions to be implemented effective January 1, 1997
(allowing $92 million of the $163 million referred to in paragraph 2 above to be
saved) and to allow the State to capture approximately $267 million in
additional federal block grant funds over the currently budgeted level. None of
the other federal changes needed to achieve the balance of the $660 million cost
savings were enacted. Thus, in lieu of the $660 million savings initially
assumed to be saved, it is now projected that savings will total approximately
$360 million.
    
 
   
     A preliminary analysis of the law by the Legislative Analyst's Office
indicates that an overall assessment of how these changes will affect the
State's General Fund will not be known for some time, and will depend on how the
State implements the Law. There are many choices including how quickly the State
implements the Law; the degree to which the State elects to make up for cuts in
federal aid, provide more aid to counties, or cut some of its own existing
programs for noncitizens; and the State's ability to avoid certain penalties
written into the Law.
    
 
   
LOCAL GOVERNMENTS
    
 
   
     The primary units of local government in California are the counties,
ranging in population from 1,300 (Alpine) to over 9,000,000 (Los Angeles).
Counties are responsible for the provision of many basic services, including
indigent healthcare, welfare, courts, jails and public safety in unincorporated
areas. There are also about 480 incorporated cities and thousands of other
special districts formed for education, utility and other
    
 
                                       44
<PAGE>   97
 
   
services. The fiscal condition of local governments has been constrained since
the enactment of "Proposition 13" in 1978, which reduced and limited the future
growth of property taxes and limited the ability of local governments to impose
"special taxes" (those devoted to a specific purpose) without two-thirds voter
approval. A recent California Supreme Court decision has upheld the
constitutionality of an initiative statute, previously held invalid by lower
courts, which requires voter approval for "general" as well as "special" taxes
at the local level. Counties, in particular, have had fewer options to raise
revenues than other local government entities and have been required to maintain
many services.
    
 
   
     In the aftermath of Proposition 13, the State provided aid from the General
Fund to make up some of the loss of property tax moneys, including taking over
the principal responsibility for funding local K-12 schools and community
colleges. Under the pressure of the recent recession, the Legislature has
eliminated remnants of this post-Proposition 13 aid to entities other than K-14
education districts, although it has also provided additional funding sources
(such as sales taxes) and reduced mandates for local services. Many counties
continue to be under severe fiscal stress. While such stress has in recent years
most often been experienced by smaller, rural counties, larger urban counties,
such as Los Angeles, have also been affected. Orange County implemented
significant reductions in services and personnel, and continues to face fiscal
constraints in the aftermath of its bankruptcy.
    
 
   
CONSTITUTIONAL AND STATUTORY LIMITATIONS; RECENT INITIATIVES; PENDING
LEGISLATION
    
 
   
     Constitutional and Statutory Limitations.  Article XIIIA of the California
Constitution (which resulted from the voter-approved Proposition 13 in 1978)
limits the taxing powers of California public agencies. Article XIIIA provides
that the maximum ad valorem tax on real property cannot exceed 1 percent of the
"full cash value" of the property and effectively prohibits the levying of any
other ad valorem tax on real property for general purposes. However, on May 3,
1986, Proposition 46, an amendment to Article XIIIA, was approved by the voters
of the State of California, creating a new exemption under Article XIIIA
permitting an increase in ad valorem taxes on real property in excess of 1
percent for bonded indebtedness approved by two-thirds of the voters voting on
the proposed indebtedness. "Full cash value" is defined as "the County
Assessor's valuation of real property as shown on the 1975-76 tax bill under
"full cash value" or, thereafter, the appraised value of real property when
purchased, newly constructed, or a change in ownership has occurred after the
1975 assessment". The "full cash value" is subject to annual adjustment to
reflect increases (not to exceed 2 percent) or decreases in the consumer price
index or comparable local data, or to reflect reductions in property value
caused by damage, destruction or other factors.
    
 
   
     Article XIIIB of the California Constitution limits the amount of
appropriations of the State and of the local governments to the amount of
appropriations of the entity for the prior year, adjusted for changes in the
cost of living, population and the services that local government has financial
responsibility for providing. To the extent that the revenues of the State
and/or local government exceed its appropriations, the excess revenues must be
rebated to the public either directly or through a tax decrease. Expenditures
for voter-approved debt services are not included in the appropriations limit.
    
 
   
     In 1986, California voters approved an initiative statute known as
Proposition 62. This initiative (i) required that any tax for general
governmental purposes imposed by a local governmental entity be approved by a
majority of the electorate of the governmental entity, (ii) required that any
special tax (defined as taxes levied for other than general government purposes)
imposed by a local governmental entity be approved by a two-thirds vote of the
voters within that jurisdiction, (iii) restricted the use of revenues from a
    
 
                                       45
<PAGE>   98
 
   
special tax to the purposes or for the services for which the special tax is
imposed, (iv) prohibited the imposition of ad valorem taxes on real property by
local governmental entities except as permitted by Article XIIIA, (v) prohibited
the imposition of transaction taxes and sales taxes on the sale of real property
by local governments, (vi) required that any tax imposed by a local government
on or after August 1, 1985 be ratified by a majority vote of the electorate
within two years of the adoption of the initiative or be terminated by November
15, 1988, (vii) required that, in the event a local government fails to comply
with the provisions of this measure, a reduction in the amount of property tax
revenues allocated to such local government occurs in an amount equal to the
revenues received by such entity attributable to the tax levied in violation of
the initiative, and (viii) permitted those provisions to be amended exclusively
by the voters of the State of California.
    
 
   
     On September 28, 1995 the California Supreme Court upheld the
constitutionality of the provision requiring a two-thirds vote in order for a
local government to impose a "special tax". Although the Supreme Court has yet
to rule on the provision requiring a majority vote for a "general tax", it
appears that the Supreme Court is favorably disposed to uphold that portion of
Proposition 62 as well. In that event, a number of taxes currently being
collected (especially by counties and general law cities) would be invalidated.
Prior collecting of such taxes may also be subject to claims for refund unless
the Supreme Court chooses to apply its ruling prospectively. The California
Supreme Court has yet to consider the validity of Proposition 62 with regard to
charter cities.
    
 
   
     Recent Initiatives.  At the November 9, 1988 general election, California
voters approved an initiative known as Proposition 98. This initiative amends
Article XIIIB to require that (i) the California Legislature establish a prudent
state reserve fund in an amount it shall deem reasonable and necessary and (ii)
revenues in excess of amounts permitted to be spent and which would otherwise be
returned pursuant to Article XIIIB by revision of tax rates or fee schedules be
transferred and allocated (up to a maximum of 40%) to the State School Fund and
be expended solely for purposes of instructional improvement and accountability.
Proposition 98 also amends Article XVI to require that the State of California
provide a minimum level of funding for public schools and community colleges.
Commencing with the 1988-89 Fiscal Year, money to be applied by the State for
the support of school districts and community college districts shall not be
less than the greater of: (i) the amount which, as a percentage of the State
General Fund revenues which may be appropriated pursuant to Article XIIIB,
equals the percentage of such State General Fund revenues appropriated for
school districts and community college districts, respectively, in Fiscal Year
1986-87 or (ii) the amount required to ensure that the total allocations to
school districts and community college districts from the State General Fund
proceeds of taxes appropriated pursuant to Article XIIIB and allocated local
proceeds of taxes shall not be less than the total amount from these sources in
the prior year, adjusted for increases in enrollment and adjusted for changes in
the cost of living pursuant to the provisions of Article XIIIB. The initiative
permits the enactment of legislation, by a two-thirds vote, to suspend the
minimum funding requirements for one year. As a result of Proposition 98, funds
that the State might otherwise make available to its political subdivisions may
be allocated instead to satisfy such minimum funding level.
    
 
   
     During the recent recession, General Fund revenues for several years were
less than originally projected, so that the original Proposition 98
appropriations turned out to be higher than the minimum percentage provided in
the law. The Legislature responded to these developments by designating the
"extra" Proposition 98 payments in one year as a "loan" from future years'
Proposition 98 entitlements and also intended that the "extra" payments would
not be included in the Proposition 98 "base" for calculating future years'
entitlement.
    
 
                                       46
<PAGE>   99
 
   
By implementing these actions, per-pupil funding from Proposition 98 sources
stayed almost constant at approximately $4,220 from Fiscal Year 1991-92 to
Fiscal Year 1993-94.
    
 
   
     In 1992, a lawsuit was filed, called California Teachers' Association v.
Gould, which challenged the validity of these off-budget loans. As part of the
negotiations leading to the 1995-96 Budget Act, an oral agreement was reached to
settle this case. The settlement was approved by the court in July 1996.
    
 
   
     The settlement provides, among other things, that both the State and K-14
schools share in the repayment of prior years' emergency loans to schools. Of
the total $1.76 billion in loans, the State will repay $935 million by
forgiveness of the amount owed, while schools will repay $825 million. The State
share of the repayment will be reflected as expenditures above the current
Proposition 98 base calculation. The schools' share of the repayment will count
as appropriations that count toward satisfying the Proposition 98 guarantee, or
from "below" the current base. Repayments are spread over the eight-year period
of 1994-95 through 2001-02 to mitigate any adverse fiscal impact. The Director
of Finance has certified that a settlement has occurred, allowing approximately
$377 million in appropriations from the 1995-96 Fiscal Year to schools to be
disbursed.
    
 
   
     On November 8, 1994, the voters approved Proposition 187, an initiative
statute ("Proposition 187"), Proposition 187 specifically prohibits funding by
the State of social services, health care services and public school education
for the benefit of any person not verified as either a United States citizen or
a person legally admitted to the United States. Among the provisions in
Proposition 187 pertaining to public school education, the measure requires,
commencing January 1, 1995, that every school district in the State verify the
legal status of every child enrolling in the district for the first time. By
January 1, 1996, each school district must also verify the legal status of
children already enrolled in the district and of all parents or guardians of all
students. If the district "reasonably suspects" that a student, parent or
guardian is not legally in the United States, that district must report the
student to the United States Immigration and Naturalization Service and certain
other parties. The measure also prohibits a school district from providing
education to a student it does not verify as either a United States citizen or a
person legally admitted to the United States. The State Legislative Analyst
estimates that verification costs could be in the tens of millions of dollars on
a statewide level (including verification costs incurred by other local
governments), with first-year costs potentially in excess of $100 million.
    
 
   
     The reporting requirements may violate the Family Educational Rights and
Privacy Act ("FERPA"), which generally prohibits schools that receive Federal
funds from disclosing information in student records without parental consent.
Compliance with FERPA is a condition of receiving Federal education funds, which
total $2.3 billion annually to California school districts. The Secretary of the
United States Department of Education has indicated that the reporting
requirements in Proposition 187 could jeopardize the ability of school districts
to receive these funds.
    
 
   
     Opponents of Proposition 187 have filed at least eight lawsuits challenging
the constitutionality and validity of the measure. On November 2, 1995, a United
States District Court judge struck down the central provisions of Proposition
187 by ruling that parts of Proposition 187 conflict with Federal power over
immigration. The ruling concluded that states may not enact their own schemes to
"regulate immigration or devise immigration regulations which run parallel or
purport to supplement Federal immigration law". As a consequence of the ruling,
students may not be denied public education and may not be asked about their
immigration status when enrolling in public schools. Further, the ruling struck
down the requirements of
    
 
                                       47
<PAGE>   100
 
   
Proposition 187 that teachers and district employees report information on the
immigrant status of students, parents and guardians. An appeal has been filed.
    
 
   
     Article XIIIA, Article XIIIB and a number of other propositions were
adopted pursuant to California's constitutional initiative process. From time to
time, other initiative measures could be adopted by California voters. The
adoption of any such initiatives may cause California issuers to receive reduced
revenues, or to increase expenditures, or both.
    
 
   
     Pending Litigation. The State is a party to numerous legal proceedings,
many of which normally occur in governmental operations. Some of the more
significant lawsuits pending against the State are described herein.
    
 
   
     The State is a defendant in 12 lawsuits involving the exclusion of small
business stock gains from preference tax and in some cases, also from taxation.
The lead cases are Mervin Morris v. Franchise Tax Board and James Lennane v.
Franchise Tax Board. The majority of the remaining cases had been deferred
pending the outcome of the Morris and Lennane cases. The Supreme Court has ruled
against the State in Lennane but has not yet ruled in Morris. The State has lost
at least $80 million as a result of the Lennane decision.
    
 
   
     In Parr v. State of California, a complaint was filed in Federal court
claiming that payment of wages in registered warrants violated the Fair Labor
Standards Act ("FLSA"). The Federal court held that the issuance of registered
warrants does violate the FLSA but subsequently withdrew its order. The parties
have agreed to a settlement which has to be approved by the trail court. Under
the terms of the judgment, a maximum of $1.3 million will be paid to eligible
separated State employees and approximately $1 million will be paid in statutory
attorney's fees and costs. In addition, eligible current State employees will
receive employee leave, in an amount presently not quantified.
    
 
   
     The State is involved in a lawsuit seeking reimbursement for alleged
state-mandated costs. In Thomas Hayes v. Commission on State Mandates, the State
Director of Finance is appealing a 1984 decision by the State Board of Control.
The Board of Control decided in favor of local school districts' claims for
reimbursement for special education programs for handicapped students; however,
funds have not been appropriated. The amount of potential liability to the
State, if all potentially eligible school districts pursue timely claims, has
been estimated by the Department of Finance at over $1 billion.
    
 
   
     In another case, the State is a defendant in Long Beach Unified School
Districts v. State of California. In this case, the school district seeks
reimbursement for voluntary desegregation costs incurred in the implementation
of California Department of Education guidelines. The years of reimbursement are
from Fiscal Year 1977-78 and each fiscal year thereafter to the present. The
district prevailed in a superior court, and the case has been decided by a State
appellate court against the State. A petition for review was denied and the
superior court judgment has become final, but the court retains jurisdiction to
oversee payment. The State anticipates that the unfavorable outcome will affect
pending claims by other school districts, and the total loss could be in excess
of $300 million.
    
 
   
     A Federal Court of Appeals in the case of Deanna Beno et al. v. Donna
Shalala, reversing a trail court ruling in favor of the State, recently
determined that the Secretary of the United States Department of Health and
Human Services violated the Federal Administrative Procedure Act when she
approved California's Assistance Payment Demonstration Project, which in part,
granted California a waiver from complying with requirements for state
participation in the Federal program for medical assistance ("Medicaid"). The
waiver
    
 
                                       48
<PAGE>   101
 
   
has allowed California to reduce payments under the Aid to Families with
Dependent Children program ("AFDC"), below 1988 payment levels without violating
Medicaid requirements relating to maintenance of AFDC payment levels. California
had relied, in part, on the waiver to reduce state AFDC payments in 1992, 1993
and 1994. The Court of Appeals remanded the case to the trail court with
instructions to remand the Demonstration Project to the Secretary for additional
consideration of objections raised by the plaintiffs. The State submitted a
renewed waiver request to the Secretary, which was granted in early 1996.
    
 
   
     One of the features of the 1994-95 Budget Act is a 2.3 percent reduction in
AFDC payments. In Welch v. Anderson, on August 19, 1994, the San Francisco
Superior Court issued a preliminary injunction against the California Director
of Social Services to prevent the 2.3 percent AFDC cuts from becoming effective
September 1, 1994. While September cuts were already in process and could not be
halted, the court ordered the cuts to be restored. The preliminary injunction
has been upheld and the case on the merits remains pending.
    
 
   
     The State is involved in two lawsuits related to contamination at the
Stringfellow toxic waste site. In one suit, the State is one of approximately
130 defendants in Penny Newman v. J.B. Stringfellow, et al. in which 3,800
plaintiffs are claiming damages of $850 million arising from contamination at
the Stringfellow toxic waste site. The State is a defendant because it chose the
site and approved the deposit of toxic wastes. Seventeen of the 3,800 plaintiffs
have litigated their claims; in half of these cases plaintiffs' verdicts in the
total amount of $159,000 were received and in the remaining cases verdicts were
entered for the State. The other cases have been settled for $13.5 million. In
the separate suit described in United States, People of the State of California
v. J.B. Stringfellow Jr. et al., the State has been found liable by the District
Court on the courterclaim. The amount of liability is still being litigated
although allocation of liability has been determined by the trial court,
including an allocation of liability to the State.
    
 
   
     The State is a defendant in a coordinated action involving 3,000 plaintiffs
seeking recovery for damages caused by the Yuba River flood of February 1986.
The appellate court affirmed the trial court finding of liability in inverse
condemnation and awarded damages of $500,000 to 12 sample plaintiffs. Potential
liability to the remaining 300 plaintiffs, from claims filed, ranges from $800
million to $1.5 billion.
    
 
   
     The State is involved in a case concerning the default by Triad Healthcare
on a $167 million loan guaranteed by the Cal-Mortgage Loan Insurance Division of
the Office of Statewide Health Planning and Development ("Cal-Mortgage"). Monies
for the loan were raised through the sale of Certificates of Participation and
Cal-Mortgage insured the debt service payments. Since July 1993, Triad has
failed to make its monthly debt service payments; therefore, the reserve account
of the bonds has been used to make the payments. Once the reserve account is
exhausted, additional debt service payments would be made from the Health
Facility Construction Loan Insurance Fund as they become due. However, if there
is any shortfall in this fund, the State's General Fund would be used to make up
the difference.
    
 
   
     In Jernigan & Burleson v. State, filed in Federal district court, the
prison inmate plaintiffs claim they are entitled to minimum wages while working
for the Prison Industry Authority. The inmates claim that the State has violated
the FLSA, Plaintiffs are seeking back pay for the period from August 1990
onward, and liquidated damages for a total of approximately $350 million. In
June 1995, the district court rules that the inmates are not employees under the
FLSA. The decision has been appealed to the Ninth Circuit Court of Appeals,
which affirmed the District Court decision holding that the inmates are not
employees under the FLSA. The inmates have filed a Petition for Rehearing and a
Petition for Hearing En Banc with the Ninth Circuit.

     Additional lawsuits challenge the transfer of moneys from special fund
accounts within the State Treasury to the State's General Fund pursuant to the
Budget Acts of 1991, 1992, 1993 and 1994. Plaintiffs in the two cases titled
Abramovitz et al. v. Wilson et al., filed in State and Federal courts, seek to
have the transfers reversed and the monies allegedly totalling approximately
$400 million returned to the special funds. Plaintiffs in the case of Kurt
Hathaway, et al. v. Wilson, filed in State court, seek to reverse transfers of
money from special fund accounts to the State's General Fund authorized in the
1994 and 1995 Budget Acts, allegedly totalling approximately $370 million. The
State disputes both liability and the amount claimed. In the case of
Professional Engineers in California Government v. Wilson, several State
employees' unions have challenged transfers made from special funds to the
General Fund pursuant to the Budget Act of 1993, 1994 and 1995 and seek
reimbursement of over $400 million to these special funds.
    
 
   
     In the case of Board of Administration, California Public Employees'
Retirement system, et al. v. Pete Wilson, Governor, et al., plaintiffs
challenged the constitutionality of legislation which deferred payment of the
State's employer contribution to the Public Employees' Retirement System
("PERS") beginning in Fiscal Year 1992-93. On January 11, 1995, the Sacramento
County Superior Court entered a judgment finding that the legislation
unconstitutionally impaired the vested contract rights of PERS members. The
judgment provides for issuance of a writ of mandate directing State defendants
to disregard the provisions of the legislation, to implement the statute
governing employer contributions that existed before the changes in the
legislation were found to be unconstitutional and to transfer to PERS the
1993-94 and 1994-95 contributions that are unpaid to date. The State defendants
have appealed.

DESCRIPTION OF MUNICIPAL BOND RATINGS OF MOODY'S INVESTORS SERVICE, INC.
("MOODY'S")
 
<TABLE>
<S>   <C>
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 payments or of maintenance of other terms of the
      contract over any long period of time may be small.
Caa   Bonds which are rated Caa are of poor standing. Such issues may be in default or there
      may be present elements of danger with respect to principal or interest.
Ca    Bonds which are rated Ca represent obligations which are speculative in a high degree.
      Such issues are often in default or have other marked shortcomings.
C     Bonds which are rated C are the lowest rated class of bonds, and issues so rated can
      be regarded as having extremely poor prospects of ever attaining any real investment
      standing.
</TABLE>
 
     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.
    
 
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 earning 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 MUNICIPAL DEBT RATINGS OF STANDARD & POOR'S RATINGS SERVICES
("STANDARD & POOR'S")
    
 
     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.
 
     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.
 
                                       52
<PAGE>   105
 
     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 an 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 reasons.
 
     The ratings are based, in varying degrees, on the following considerations:
 
<TABLE>
<S>   <C>
  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 by, and relative position of, the obligation in the event of
      bankruptcy, reorganization or other arrangement under the laws of bankruptcy and
      other laws affecting creditors' rights.
        AAA  Debt rated "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  Debt rated "BB", "B", "CCC", "CC" and "C" is regarded, on balance, as
          B  predominately speculative with respect to capacity to pay interest and repay
        CCC  principal in accordance with the terms of the obligations. "BB" indicates the
         CC  lowest degree of speculation and "C" the highest degree of speculation. While
          C  such debt will likely have some quality and protective characteristics, these
             are outweighed by large uncertainties or major exposures to adverse conditions.
         CI  The rating "CI" 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 of 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.
</TABLE>
 
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
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 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. Ratings are applicable to
both taxable and tax-exempt commercial paper. Issues assigned the highest rating
are regarded as having the greatest capacity for timely payment. Issues in this
category are further refined with the designation 1, 2, and 3 to indicate the
relative degrees of safety. Issues in the "A" category are as follows:
    
 
   
<TABLE>
    <S>    <C>
     A-1   This designation indicates that the degree of safety regarding timely payment is
           either overwhelming or very 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 S&P believes that such payments
           will be made during such grace period.
</TABLE>
    
 
     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 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.
 
                                       54
<PAGE>   107
 
   
     A Standard & Poor's note rating reflects the liquidity concerns and market
access risks unique to notes. Notes due in three years or less will likely
receive a note rating. Notes maturing beyond three 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.
 
     Standard & Poor's may continue to rate note issues with a maturity greater
than three years in accordance with the same rating scale currently employed for
municipal bond ratings.
 
     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 are 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. ("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 operating performance of the issuer and of any
guarantor, as well as the economic and political environment that might affect
the issuer's future financial strength and credit quality.
 
                                       55
<PAGE>   108
 
     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.
 
<TABLE>
    <S>    <C>
     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 foreseeable events.
      AA   Bonds considered to be investment grade and of very high credit 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.
</TABLE>
 
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:
 
<TABLE>
                            <S>                          <C>
                            Improving                    [arrow up]
                            Stable                       [arrow left and right]
                            Declining                    [arrow down]
                            Uncertain                    [arrow up and down]
</TABLE>
 
Credit trend indicators are not predictions that any rating change will occur,
and have a longer-term time frame than issues placed on FitchAlert.
 
                                       56
<PAGE>   109
 
   
<TABLE>
<S>             <C>
           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 an 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.
</TABLE>
    
 
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 particular 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, its
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.
 
                                       57
<PAGE>   110
 
   
     Bonds that have the same rating are of similar but not necessarily
identical credit quality since rating categories cannot fully reflect the
differences in degree of credit risk.
    
 
<TABLE>
<S>             <C>
            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.
            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 D  Bonds are in default on interest and/or principal payments. 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.
</TABLE>
 
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 "DDD", "DD", or "D" categories.
 
DESCRIPTION OF FITCH INVESTMENT GRADE SHORT-TERM RATINGS
 
     Fitch's 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.
 
                                       58
<PAGE>   111
 
     Fitch short-term ratings are as follows:
 
<TABLE>
    <S>    <C>
     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 for
           issues assigned "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 assigned 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.

MERRILL LYNCH CALIFORNIA MUNICIPAL BOND FUND                AUGUST 31, 1996



NOTES TO FINANCIAL STATEMENTS



1. Significant Accounting Policies:
Merrill Lynch California Municipal Bond Fund (the "Fund") is part of
Merrill Lynch California Municipal Series Trust (the "Trust"). The
Fund is registered under the Investment Company Act of 1940 as a
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 contracts 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) Prepaid registration fees--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 on the ex-dividend dates. Distributions in excess
of realized capital gains are due primarily to differing tax
treatments for futures transactions.

MERRILL LYNCH CALIFORNIA MUNICIPAL BOND FUND                AUGUST 31, 1996


(g) Reclassification--Generally accepted accounting principles
require that certain components of net assets be reclassified to
reflect permanent differences between financial reporting and tax
purposes. Accordingly, current year's permanent book/tax differences
of $98 have been reclassified from paid-in capital in excess of par
to accumulated net realized capital losses. These reclassifications
have no effect on net assets or net asset values per share.

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
remaining average net assets. FAM's obligation to reimburse the Fund
is limited to the amount of the management fee. No fee payment will
be made during any fiscal year which will cause such expenses to
exceed expense limitations at the time of such 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 August 31, 1996, 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                                $2,185        $18,776
Class D                                $2,960        $28,248


For the year ended August 31, 1996, MLPF&S received contingent
deferred sales charges of $427,650 and $4,398 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 August 31, 1996 were $336,637,182 and
$422,327,530, 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 which it is ultimately determined 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 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
Trustee, 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.

P.O. Box 9011

Ladies and Gentlemen:

         This opinion is furnished in connection with the registration by
Merrill Lynch California Municipal Series Trust, a Massachusetts business trust
(the "Trust"), of shares of beneficial interest, par value $0.10 per share (the
"Shares") of the Merrill Lynch California Municipal Bond Fund, a series of the
Trust, under the Securities Act of 1933, as amended, pursuant to a registration
statement on Form N-1A (File No. 2-96581), as amended (the "Registration
Statement"), in the amount set forth under "Amount Being Registered" on the
facing page of 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.




<PAGE>   2
         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 non-assessable 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.



                                       Very truly yours,

                                       /s/ Brown & Wood LLP
