   PROSPECTUS
   ---------- 
      
   October 21, 1994
     
                    Merrill Lynch Municipal Bond Fund, Inc.
   
   P.O. Box 9011, Princeton, New Jersey 08543-9011 - Phone No. (609) 282-2800
    

       Merrill Lynch Municipal Bond Fund, Inc. (the "Fund") is a 
   professionally managed, diversified, open-end investment company which 
   seeks to provide shareholders with as high a level of income exempt from 
   Federal income taxes as is consistent with the investment policies of each 
   of its Portfolios and prudent investment management. The Fund is a series 
   fund and is comprised of three separate Portfolios, each of which invests 
   primarily in a diversified portfolio of tax-exempt Municipal Bonds, 
   principally consisting of state, municipal and public authority 
   securities. Each of the Portfolios pursues its investment objective 
   through the separate investment policies described below: 

       Insured Portfolio invests primarily in long-term, investment grade 
   Municipal Bonds, each of which is covered by portfolio insurance 
   guaranteeing the timely payment of principal at maturity and interest. 

       National Portfolio invests primarily in long-term medium to lower 
   grade Municipal Bonds offering higher yields than the Insured Portfolio 
   but also subject to greater risks than investment grade Municipal Bonds. 

       Limited Maturity Portfolio invests in a portfolio primarily of 
   investment grade Municipal Bonds with a maximum maturity not to exceed 
   four years and, depending on market conditions, an average maturity of 
   less than two years is anticipated. The Limited Maturity Portfolio can be 
   expected to offer the lowest yield of the three Portfolios, but it will be 
   subject to less market risk than the longer-term Portfolios.
   
       Each Portfolio is, in effect, a separate fund issuing its own shares. 
   Pursuant to the Merrill Lynch Select Pricing SM System, each Portfolio of 
   the Fund offers four classes of shares, each with a different combination 
   of sales charges, ongoing fees and other features. Class C shares of the 
   Limited Maturity Portfolio are available only through the Exchange 
   Privilege. The Merrill Lynch Select Pricing 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 8.
       Class A and Class D shares of the Fund's Portfolios may be purchased 
   directly from Merrill Lynch Funds Distributor, Inc. ("the Distributor"), 
   P.O. Box 9011, Princeton, New Jersey 08543-9011 (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"). Class B and Class C shares of the Fund's 
   Portfolios may only be purchased either directly from the Distributor or 
   Merrill Lynch. See "Purchase of Shares" below. The minimum initial 
   purchase for shares of each Portfolio is $1,000, and the minimum 
   subsequent purchase in each Portfolio 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 net investment income of each 
   Portfolio is declared daily and paid monthly.

       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 Securities and Exchange 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 charges 
   permitted under the Rules of Fair Practice of the National Association of 
   Securities Dealers, Inc. ("NASD"). Merrill Lynch may charge its 
   customers a processing fee (presently $4.85) for confirming purchases and 
   redemptions. Purchases and redemptions directly through the Fund's 
   transfer agent are not subject to the processing fee. See "Purchase of

       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 Securities and Exchange 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 charges 
   permitted under the Rules of Fair Practice of the National Association of 
   Securities Dealers, Inc. ("NASD"). Merrill Lynch may charge its 
   customers a processing fee (presently $4.85) for confirming purchases and 
   redemptions. Purchases and redemptions directly through the Fund's 
   transfer agent are not subject to the processing fee. See "Purchase of 
   Shares" and "Redemption of Shares."

                     MERRILL LYNCH SELECT PRICING SM SYSTEM

       Each Portfolio of the Fund offers four classes of shares under the 
   Merrill Lynch Select Pricing SM System. The shares of each class may be 
   purchased at a price equal to the next determined net asset value per 
   share subject to the sales charges and ongoing fee arrangements described 
   below. Shares of Class A and Class D are sold to investors choosing the 
   initial sales charge alternatives, and shares of Class B and for the 
   Insured and National Portfolios only Class C are sold to investors 
   choosing the deferred sales charge alternatives. Class C shares of the 
   Limited Maturity Portfolio are offered only through the exchange privlege 
   and may not be purchased except through exchange of Class C shares of 
   another Portfolio or another Fund. The Merrill Lynch Select Pricing SM 
   System is used by more than 50 mutual funds advised by Merrill Lynch Asset 
   Management, L.P. ("MLAM") or its affiliate, Fund Asset Management, L.P. 
   ("FAM" or the "Investment Adviser"). Funds advised by MLAM or FAM are 
   referred to herein as "MLAM-advised mutual funds."

       Each Class A, Class B, Class C or Class D share of one of the Fund's 
   Portfolios represents an identical interest in the investment portfolio of 
   the applicable Portfolio and has the same rights, except that Class B, 
   Class C and Class D shares bear the expenses of the ongoing account 
   maintenance fees and Class B and Class C shares bear the expenses of the 
   ongoing distribution fees and the additional incremental transfer agency 
   costs resulting from the deferred sales charge arrangements. The deferred 
   sales charges and account maintenance fees that are imposed on Class B and 
   Class C shares of a Portfolio, as well as the account maintenance fees 
   that are imposed on the Class D shares, will be imposed directly against 
   those classes and not against all assets of the relevant Portfolio 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 a Portfolio for each class of shares will be 
   calculated in the same manner at the same time and will differ only to the 
   extent that account maintenance and distribution fees and any incremental 
   transfer agency costs relating to a particular class are borne exclusively 
   by that class. Each class has different exchange privileges. See 
   "Shareholder Services-Exchange Privilege."

       Investors should understand that the purpose and function of the 
   initial sales charges with respect to the Class A and Class D shares are 
   the same as those of the deferred sales charges with respect to the Class 
   B and Class C shares in that the sales charges applicable to each class 
   provide for the financing of the distribution of the shares of the Fund. 
   The distribution-related revenues paid with respect to a class will not be 
   used to finance the distribution expenditures of another class. Sales 
   personnel may receive different compensation for selling different classes 
   of shares.

       The following table sets forth a summary of the distribution 
   arrangements for each class of shares under the Merrill Lynch Select 
   Pricing SM System, followed by a more detailed description of each class 
   and a discussion of the factors that investors should consider in 
   determining the method of purchasing shares under the Merrill Lynch Select 
   Pricing SM System that the investor believes is most beneficial under his 
   particular circumstances. More detailed information as to each class of 
   shares is set forth under "Purchase Shares."

   (1) Initial sales charges are imposed at the time of purchase as a 
       percentage of the offering price. Contingent deferred sales charges 
       ("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

   (3) Reduced for purchases of $25,000 or more for the Insured and National 
       Portfolios and $100,000 or more for the Limited Maturity Portfolio. 
       Class A and Class D share purchases of $1,000,000 or more will not be 
       subject to an initial sales charge but instead will be subject to a 1.0% 
       CDSC for the Insured and National Portfolios and a .20% CDSC for the 
       Limited Maturity Portfiolio, for one year. See "Class A" and
       "Class D" below.

   (4) The conversion period for dividend reinvestment shares is modified. 
       Also, Class B shares of certain other MLAM-advised mutual funds into 
       which exchanges may be made have a 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.

   (5) Class C shares of the Limited Maturity Portfolio are available only 
       through the Exchange Privilege. See p. 42.

  Class  A: Class A shares incur an initial sales charge when they are
            purchased and bear no ongoing distribution or account maintenance
            fees. Class A shares are offered to a limited group of investors and
            also will be issued upon reinvestment of dividends on outstanding
            Class A shares. Investors that currently own Class A shares in a
            shareholder account are entitled to purchase additional Class A
            shares in that account. Other eligible investors include
            participants in certain investment programs. In addition, Class A
            shares will be offered to Merrill Lynch & Co., Inc. and its
            subsidiaries (including MLAM) (the term "subsidiaries," when used
            herein with respect to Merrill Lynch & Co., Inc., includes MLAM, FAM
            and certain other entities indirectly by wholly-owned and controlled
            by Merrill Lynch & Co., Inc.) and their directors and employees and
            to members of the Boards of MLAM-advised mutual funds. The maximum
            initial sales charge is 4.00% for the Insured and National
            Portfolios and 1.00% for the Limited Maturity Portfolio and is
            reduced for purchases of $25,000 and over for the Insured and
            National Portfolios and for purchases of $100,000 or over for the
            Limited Maturity Portfolio. Purchases of $1,000,000 or more will not
            be subject to an initial sales charge but such purchases will be
            subject to a CDSC of 1.0% if the shares are redeemed within one 
            year after purchase. Sales charges also are reduced under a right
            of accumulation which takes into account the investors'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% (in the case of the Insured Portfolio and the National
            Portfolio) and 0.15% (in the case of the Limited Maturity Portfolio)
            of the Portfolio's average net assets attributable to the Class B
            shares, an ongoing distribution fee of 0.50% (in the case of the
            Insured Portfolio and the National Portfolio) and 0.20% (in the case
            of the Limited Maturity Portfolio) of the Portfolio's average net
            assets attributable to Class B shares and a CDSC if they are
            redeemed within four years of purchase (in the case of the Insured
            Portfolio and National Portfolio) and within one year of purchase
            (in the case of the Limited Maturity Portfolio). Approximately ten
            years after issuance, Class B shares of the Portfolio will convert
            automatically into Class D shares of the Portfolio, which are
            subject to an account maintenance fee but 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 a Portfolio
            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. Automatic conversion of Class B shares into Class D
            shares will occur at least once a month on the basis of the relative
            net asset values of the shares of the two classes on the conversion
            date, without the imposition of any sales load, fee or other charge.
            Conversion of Class B shares to Class D shares will not be deemed a
            purchase or sale of the shares for 
    


                                       10

             Federal income tax purposes. Shares purchased through reinvestment
             of dividends on Class B shares also will convert automatically to
             Class D shares. The conversion period for dividend reinvestment
             shares is modified as described under "Purchase of Shares-Deferred
             Sales Charge Alternatives-Class B and Class C Shares-Conversion of
             Class B Shares to Class D Shares."

   Class C: Class C shares do not incur a sales charge when they are 
            purchased, but they are subject to an ongoing account maintenance 
            fee of 0.25% (in the case of the Insured Portfolio and the 
            National Portfolio) and 0.15% (in the case of the Limited 
            Maturity Portfolio) of average net assets and an ongoing 
            distribution fee of 0.55% (in the case of the Insured Portfolio 
            and the National Portfolio) and 0.20% (in the case of the Limited 
            Maturity Portfolio) of average net assets. Class C shares are 
            also subject to a CDSC if they are redeemed within one year of 
            purchase. Although Class C shares are subject to a 1.0% CDSC for 
            only one year (as compared to four years for Class B of the 
            Insured Portfolio and National Portfolio), Class C shares have no 
            conversion feature and, accordingly, an investor that purchases 
            Class C shares will be subject to distribution fees that will be 
            imposed on Class C shares for an indefinite period subject to 
            annual approval by the Fund's Board of Directors and regulatory 
            limitations. Class C shares of the Limited Maturity Portfolio are 
            available only through the Exchange Privilege. See p. 42.

   Class D: Class D shares incur an initial sales charge when they are 
            purchased and are subject to an ongoing account maintenance fee 
            of 0.25% (in the case of the Insured Portfolio and the National 
            Portfolio) and 0.10% (in the case of the Limited Maturity 
            Portfolio) of average net assets. 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 will not be subject to 
            an initial sales charge but such purchase will be subject to a CDSC
            of 1% if the shares are redeemed within one year after purchase. The
            schedule of initial sales charges and reductions for Class D shares
            is the same as the schedule for Class A shares. Class D shares also
            will be issued upon conversion of Class B shares as described above
            under "Class B." See "Purchase of Shares-Initial Sales Charge
            Alternatives-Class A and Class D Shares."
 
       The following is a discussion of the factors that investors should 
   consider in determining the method of purchasing shares under the Merrill 
   Lynch Select Pricing SM System that the investor believes is most 
   beneficial under his particular circumstances.
     
       Initial Sales Charge Alternatives. Investors who prefer an initial 
   sales charge alternative may elect to purchase Class D shares or, if an 
   eligible investor, Class A shares. Investors choosing the initial sales 
   charge alternative who are eligible to purchase Class A shares should 
   purchase Class A shares rather than Class D shares because of the account 
   maintenance fee imposed on Class D shares. Investors qualifying for 
   significantly reduced initial sales charges may find the initial sales 
   charge alternative particularly attractive because similar sales charge 
   reductions are not available with respect to the deferred sales charges 
   imposed in connection with purchases of Class B or Class C shares. 
   Investors not qualifying for reduced initial sales charges who expect to 
   maintain their investment for an extended period of time also may elect to 
   purchase Class A or Class D shares, because over time the accumulated 
   ongoing account maintenance and distribution fees on Class B or Class C 
   shares may exceed the initial sales charge 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 ongoing Class B 
                                      11
   <PAGE> 14 

   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 of a Portfolio will be converted into Class D shares of that 
   Portfolio after a conversion period of approximately ten years, and 
   thereafter investors will be subject to lower ongoing fees.

       Certain investors may elect to purchase Class B shares if they 
   determine it to be most advantageous to have all their funds invested 
   initially and intend to hold their shares for an extended period of time. 
   Investors in Class B shares should take into account whether they intend 
   to redeem their shares within the CDSC period and, if not, whether they 
   intend to remain invested until the end of the conversion period and 
   thereby take advantage of the reduction in ongoing fees resulting from the 
   conversion into Class D shares. Other investors, however, may elect to 
   purchase Class C shares if they determine that it is advantageous to have 
   all their assets invested initially and they are uncertain as to the 
   length of time they intend to hold their assets in MLAM-advised mutual 
   funds. Although Class C shareholders are subject to a shorter CDSC period 
   at a lower rate, they 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 income taxes as is 
   consistent with the investment policies of each Portfolio and prudent 
   investment management. The Fund is comprised of three separate portfolios, 
   Insured Portfolio, National Portfolio and Limited Maturity Portfolio, each 
   of which is, in effect, a separate fund issuing its own shares. Each 
   Portfolio seeks to achieve its objective by investing in a diversified 
   portfolio of obligations issued by or on behalf of states, territories and 
   possessions of the United States and the District of Columbia and their 
   political subdivisions, agencies and instrumentalities, the interest from 
   which is exempt from federal income tax (such obligations are herein 
   referred to as "Municipal Bonds"). Municipal Bonds include general 
   obligations bonds; revenue or special obligation bonds, industrial 
   development bonds, variable rate demand notes, and short-term tax-exempt 
   municipal obligations such as tax anticipation notes. Each Portfolio at 
   all times, except during temporary defensive periods, maintains at least 
   80% of its net assets invested in Municipal Bonds. In addition, each 
   Portfolio may not purchase securities other than Municipal Bonds and 
   Temporary Investments described below. These are fundamental policies of 
   each Portfolio and may not be changed without a vote of the majority of 
   the outstanding shares of the Portfolio. Each Portfolio currently 
   contemplates that it will not invest more than 25% of its total assets 
   (taken at market value) in Municipal Bonds whose issuers are located in 
   the same state. There can be no assurance that the objective of any 
   Portfolio can be attained. 

       While the Fund does not intend to realize taxable investment income, 
   each Portfolio has the authority to invest as much as 20% of its net 
   assets on a temporary basis in taxable money market securities with a 
   remaining maturity not in excess of one year from the date of purchase 
   ("Temporary Investments") for liquidity purposes or as a temporary 
   investment of cash pending investment of such cash in Municipal Bonds. 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 Investment Adviser, market conditions 
   warrant. Temporary Investments consist of U.S. Government securities, U.S. 
   Government agency securities, domestic bank certificates of deposit and 
   bankers' acceptances, short-term corporate debt securities such as 
   commercial paper, and repurchase agreements. From time to time, the Fund 
   may realize capital gains, which will constitute taxable income. In 
   addition, the Fund may invest in certain tax-exempt securities which are 
   classified as "private activity bonds," which may subject certain 
   investors to an alternative minimum tax. At June 30, 1994, the Fund's 
   Insured Portfolio, National Portfolio and Limited Maturity Portfolio did 
   not hold any "private activity bonds." These figures should not be 
   considered representative of the respective Portfolio's private activity 
   bond positions for any future period. See "Dividends, Distributions and 
   Taxes." 

       Certain instruments in which the Fund may invest may be characterized as
   derivative instruments. The National Portfolio and the Limited Maturity
   Portfolio are authorized to engage in transactions in financial futures
   contracts for hedging purposes. For a more complete description of futures
   transactions, see "Financial Futures Contracts and Derivatives" below and the
   Statement of Additional Information.

       Investment in the Fund offers several benefits. The Fund offers 
   investors the opportunity to receive income exempt from federal income 
   taxes from a diversified, professionally managed portfolio of Municipal 
   Bonds. The Fund also provides liquidity because of its redemption features 
   and relieves the investor of the burdensome administrative details 
   involved in managing a portfolio of tax-exempt securities. The benefits 
   are at least partially offset by the fact that there are expenses in 
   operating an investment company. Such expenses consist primarily of the 
   investment advisory fee and operational expenses, including, in the case 
   of the Insured Portfolio, premiums for insurance on portfolio securities.

                     INVESTMENT POLICIES OF THE PORTFOLIOS 

       Each Portfolio pursues its investment objective through the separate 
   investment policies described below. These policies differ with respect to 
   the maturity and quality of portfolio securities in which a Portfolio may 
   invest, and these policies can be expected to affect the yield on each 
   Portfolio and the degree of market and financial risk to which the 
   Portfolio is subject. Generally, Municipal Bonds with longer maturities 
   tend to produce higher yield and are subject to greater market 
   fluctuations as a result of changes in interest rates ("market risk") 
   than are Municipal Bonds with shorter maturities. Generally, lower rated 
   Municipal Bonds will provide a higher yield than higher rated Municipal 
   Bonds of similar maturity but are subject to greater market risk and are 
   also subject to a greater degree of risk with respect to the ability of 
   the issuer to meet its principal and interest obligations ("financial 
   risk"). See "Additional Information - Rating Information" for 
   information with respect to ratings assigned to Municipal Bonds and 
   Temporary Investments by rating agencies. 

                               INSURED PORTFOLIO 

       The Insured Portfolio may invest in investment grade Municipal Bonds 
   covered by portfolio insurance guaranteeing the timely payment of 
   principal at maturity and interest. Investment grade Municipal Bonds are 
   those rated at the date of purchase in the four highest rating categories 
   of Standard & Poor's Corporation (AAA, AA, A and BBB) or Moody's Investors 
   Service, Inc. (Aaa, Aa, A and Baa) in the case of long-term debt, rated 
   MIG 1 through MIG 4 by Moody's Investors Service or in the four highest 
   bond ratings of, or rated SP-1+ through SP-2 by, Standard & Poor's 
   Corporation in the case of short-term notes, and rated P-1 or P-2 in the 
   case of Moody's Investors Service or A-1+ through A-2 by Standard & Poor's 
   Corporation in the case of tax-exempt commercial paper. Depending on 
   market conditions, it is expected that long-term Municipal Bonds will 
   comprise a major portion of this Portfolio. 

       The Insured Portfolio may invest only in Municipal Bonds that, at the 
   time of purchase, either (1) are insured under an insurance policy 
   purchased by the Fund or (2) are insured under an insurance policy 
   obtained by the issuer thereof or any other party from an insurance 
   carrier meeting the criteria of the Fund set forth below. The Fund has 
   purchased from AMBAC Indemnity Corporation ("AMBAC"), Municipal Bond 
   Investors Assurance Corporation ("MBIA") and Financial Security 
   Assurance Inc. ("FSA"), separate Mutual Fund Insurance Policies (the 
   "Policies"), each of which guarantees the payment of principal and 
   interest on specified eligible Municipal Bonds purchased by the Insured 
   Portfolio ("Insured Municipal Bonds"). Consequently, some of the Insured 
   Municipal Bonds in the Insured Portfolio may be insured by AMBAC, while 
   others may be insured by MBIA or FSA. The Policies generally have the same 
   characteristics and features. A Municipal Bond is eligible for coverage if 
   it meets certain requirements of the insurance company set forth in a 
   Policy. Additional information regarding these eligibility requirements is 
   set forth in the Statement of Additional Information. In the event 
   interest or principal on an Insured Municipal Bond is not paid when due, 
   AMBAC or MBIA or FSA (depending on which Policy covers the bond) is 
   obligated under its Policy to make payment not later than 30 days after it 
   has been notified by, and provided with documentation from, the Fund that 
   such nonpayment has occurred. The insurance feature reduces financial 
   risk, but the cost thereof and the restrictions on investments imposed by 
   the guidelines in the insurance policy reduce the yield to shareholders. 

       The Policies will be effective only as to Insured Municipal Bonds 
   beneficially owned by the Insured Portfolio. In the event of a sale of any 
   Municipal Bonds held by the Insured Portfolio, the issuer of the relevant 
   Policy is liable only for those payments of interest and principal which 
   are then due and owing. The Policies do not guarantee the market value of 
   the Insured Municipal Bonds or the value of the shares of the Insured 














                                       17
   <PAGE> 20 

   Portfolio. It is the intention of the Insured Portfolio, however, to 
   retain any insured securities which are in default or in significant risk 
   of default and to place a value on the insurance, which ordinarily will be 
   the difference between the market value of the defaulted security and the 
   market value of similar securities which are not in default. In certain 
   circumstances, however, the Fund's management may determine that an 
   alternative value for the insurance, such as the difference between the 
   market value of the defaulted security and its par value, is more 
   appropriate. As the result of the value placed on the insurance with 
   respect to securities held in the Insured Portfolio which were in default 
   at the end of the Fund's last fiscal year, such securities were 
   effectively valued at par. The Insured Portfolio will be unable to manage 
   the portfolio to the extent it holds defaulted securities, which may limit 
   its ability in certain circumstances to purchase other Municipal Bonds. 
   See "Net Asset Value" in the Statement of Additional Information for a 
   more complete description of the Insured Portfolios method of valuing 
   defaulted securities and securities which have a significant risk of 
   default. Further information with respect to the portfolio insurance is 
   also set forth in the Statement of Additional Information. 

       AMBAC, MBIA and FSA may not withdraw coverage on securities insured by 
   their Policies and held by the Insured Portfolio so long as they remain in 
   the Portfolio. AMBAC, MBIA and FSA may not cancel their Policies for any 
   reason except failure to pay premiums when due. AMBAC and FSA have 
   reserved the right at any time upon written notice to the Fund to refuse 
   to insure any additional municipal securities purchased by the Insured 
   Portfolio after the effective date of such notice. The Board of Directors 
   of the Fund has reserved the right to terminate any of the Policies if it 
   determines that the benefits to the Insured Portfolio of having its 
   portfolio insured are not justified by the expense involved. 

       The premiums for the Policies are paid by the Insured Portfolio and 
   the yield on the Portfolio is reduced thereby. The Investment Adviser 
   estimates that the current cost of the annual premiums will range from 
   approximately .08% to .20% of the average net assets of the Insured 
   Portfolio. The estimate is based on the expected composition of the 
   Portfolio. 

                               NATIONAL PORTFOLIO 

       The National Portfolio invests in a portfolio primarily of long-term 
   medium to lower grade Municipal Bonds. This Portfolio normally can be 
   expected to offer the highest yields of the three Portfolios, but it will 
   also be subject to the highest market and financial risks. Because an 
   investment in the National Portfolio entails relatively greater risks, it 
   may not be an appropriate investment for all investors. 

       The investment policies of the National Portfolio are not governed by 
   specific rating categories. Management of the Fund will seek primarily 
   medium and lower grade Municipal Bonds, including short-term tax-exempt 
   notes, tax-exempt commercial paper and variable rate tax-exempt demand 
   notes. Medium grade long-term debt obligations are those rated A and BBB 
   by Standard & Poor's or A and Baa by Moody's and unrated obligations of 
   comparable quality. Lower grade obligations (commonly known as "junk 
   bonds") are those rated below BBB or Baa and unrated obligations of 
   comparable quality. Lower grade obligations will generally be more 
   speculative with respect to the capacity of the issuer to make interest 
   and principal payments. Because issuers of Municipal Bonds having these 
   characteristics may choose not to have their obligations rated, it is 
   possible that a substantial portion of the National Portfolio's portfolio 
   may consist of obligations which are not rated. Unrated bonds are not 
   necessarily of lower quality than rated bonds, but the market for rated 
   bonds is often broader. It is not the present intention of the Portfolio 
   to invest over 35% of its assets in securities rated below Baa by Moody's 
   or in securities rated below BBB by Standard & Poor's. 















                                       18
   <PAGE> 21 

       Junk bonds are considered by Standard & Poor's and Moody's to have 
   varying degrees of speculative characteristics. Consequently, although 
   junk bonds 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 junk bonds will be made only when, in the judgment of the Fund's 
   management, such securities provide attractive total return potential 
   relative to the risk of such securities, as compared to higher quality 
   debt securities. The National Portfolio will not invest in debt securities 
   in the lowest rating categories (those rated CC or lower by Standard & 
   Poor's or Ca or lower by Moody's) unless the Fund's management 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 National Portfolio does not intend to purchase debt 
   securities that are in default or which the Fund's management believes 
   will be in default. The Statement of Additional Information contains a 
   more detailed description of the risks involved in purchasing junk bonds. 

       The table below shows the average monthly dollar-weighted market 
   value, by Standard & Poor's rating category, of the securities held by the 
   National Portfolio during the year ended June 30, 1994:

       It is expected that the National Portfolio will consist primarily of 
   revenue bonds emphasizing hospital, health care, public utility and 
   housing issues. 

                           LIMITED MATURITY PORTFOLIO 

       The Limited Maturity Portfolio invests in a portfolio primarily of 
   short-term investment grade Municipal Bonds. Municipal Bonds in the 
   Limited Maturity Portfolio will be either Municipal Bonds with a remaining 
   maturity of less than four years or short-term municipal notes, which 
   typically are issued with a maturity of not more than one year. The 
   Limited Maturity Portfolio will treat Municipal Bonds which it has the 
   option to require the issuer to redeem within four years as having a 
   remaining maturity of less than four years, even if the period to the 
   stated maturity date of such Bonds is greater than four years. Municipal 
   notes include tax anticipation notes, bond anticipation notes and revenue 
   anticipation notes. The Limited Maturity Portfolio can be expected to 
   offer a lower yield than the longer-term Portfolios. Interest rates on 
   short-term Municipal Bonds may fluctuate more widely from time to time 
   than interest rates on long-term Municipal Bonds. However, because of the 
   shorter maturities, the market value of the Municipal Bonds held by the 
   Limited Maturity Portfolio can be expected to fluctuate less in value as a 
   result of changes in interest rates. 

       The Limited Maturity Portfolio will invest only in Municipal Bonds 
   rated at the date of purchase in the four highest ratings of Standard & 
   Poor's (AAA, AA, A and BBB) or Moody's (Aaa, Aa, A and Baa) in the case of 
   long-term debt, rated by Moody's as MIG 1 through MIG 4 or in the four 
   highest bond ratings of, or rated 












                                       19

   SP-1+ through SP-2 by, Standard & Poor's in the case of short-term 
   tax-exempt notes, and rated by Moody's P-1 through P-2 or rated A-1+ 
   through A-2 by Standard & Poor's in the case of tax-exempt commercial 
   paper. The Limited Maturity Portfolio will also invest in other Municipal 
   Bonds deemed to qualify for such ratings and in variable rate tax-exempt 
   demand notes. Securities rated in the lowest of these categories are 
   considered to have some speculative characteristics. The Limited Maturity 
   Portfolio may continue to hold securities which, after being purchased by 
   the Portfolio, are downgraded to a rating lower than those set forth 
   above. 

   Forward Commitments 

       Each Portfolio may purchase Municipal Bonds on a forward commitment 
   basis at fixed purchase terms. The purchase will be recorded on the date 
   the Portfolio enters into the commitment and the value of the security 
   will thereafter be reflected in the calculation of the Portfolio's net 
   asset value. The value of the security on the delivery date may be more or 
   less than its purchase price. A separate account of the Portfolio will be 
   established with its custodian consisting of cash or liquid Municipal 
   Bonds having a market value at all times at least equal to the amount of 
   the forward commitment. 

   Financial Futures Contracts and Derivatives 

       The National Portfolio and the Limited Maturity Portfolio 
   (collectively, the "Portfolios") are authorized to purchase and sell 
   certain financial futures contracts ("futures contracts") and options on 
   such futures contracts solely for the purpose of hedging their investments 
   in Municipal Bonds against declines in value and to hedge against 
   increases in the cost of securities the Portfolios intend to purchase. A 
   financial futures contract obligates the seller of a contract to deliver 
   and the purchaser of a contract to take delivery of the type of financial 
   instrument covered by the contract or, in the case of index-based futures 
   contracts, to make and accept a cash settlement, at a specific future time 
   for a specified price. A sale of financial futures contracts may provide a 
   hedge against a decline in the value of portfolio securities because such 
   depreciation may be offset, in whole or in part, by an increase in the 
   value of the position in the 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. 

       The Portfolios intend to trade in futures contracts based upon The 
   Bond Buyer Municipal Bond Index, a price-weighted measure of the market 
   value of 40 large, recently issued tax-exempt bonds, and to engage in 
   transactions in exchange-traded futures contracts on U.S. Treasury 
   securities and options on such futures. If making or accepting delivery of 
   the underlying commodity is not desired, a position in a futures contract 
   or an option on a futures contract may be terminated only by entering into 
   an offsetting transaction on the exchange on which the position was 
   established and only if there is a liquid market for such contract. If it 
   is not economically practicable, or otherwise possible to close a futures 
   position or certain option positions entered into by a Portfolio, the 
   Portfolio could be required to make continuing daily cash payments of 
   variation margin in the event of adverse price movements. In such 
   situations, if the Portfolio 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. In addition, the Portfolio may be 
   required to perform under the terms of its contracts. The inability to 
   close futures or options positions could also have an adverse impact on 
   the Portfolio's ability to hedge effectively. There is also risk of loss 
   by a Portfolio of margin deposits in the event of bankruptcy, of a broker 
   with whom the 















                                       20
   <PAGE> 23 

   Portfolio has an open position in a futures contract, or the exchange or 
   clearing organization on which that contract is traded. The Portfolios may 
   also engage in transactions in other futures contracts, such as futures 
   contracts on other municipal bond indexes which may become available, if 
   the Investment Adviser believes such contracts would be appropriate for 
   hedging the Portfolios' investments in Municipal Bonds. 
   
       Utilization of futures or option contracts involves the risk of 
   imperfect correlation in movements in the price of such contracts and 
   movements in the price of the security or securities which are the subject 
   of the hedge. If the price of the futures or option contract moves more or 
   less than the price of the security or securities that are the subject of 
   the hedge, a Portfolio will experience a gain or loss which will not be 
   completely offset by movements in the price of such security, which could 
   occur as a result of many factors, including where the securities 
   underlying futures or option 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 an index futures contract. The trading of 
   futures contracts or options on futures contracts based on indexes of 
   securities also involves a risk of imperfect correlation between the value 
   of the futures contracts and the value of the underlying index. The 
   anticipated spread between such values or in the correlation between the 
   futures contract and the underlying security may be affected by 
   differences in markets, such as margin requirements, market liquidity and 
   the participation of speculators in the futures markets. Moreover, when a 
   Portfolio enters into transactions in futures contracts on U.S. Treasury 
   securities, or options on such contracts, the underlying securities will 
   not correspond to securities held by the Portfolio. Finally, in the case 
   of futures contracts on U.S. Treasury securities and options on such 
   futures contracts, the anticipated correlation of price movements between 
   U.S. Treasury 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 Portfolios' being deemed to be "commodity pools," as 
   defined under such regulations, provided that certain restrictions are 
   adhered to. In particular, among other requirements, the Portfolios may 
   either (a) purchase and sell futures contracts only for bona fide hedging 
   purposes, as defined under CFTC regulations, or (b) limit any transaction 
   not qualifying as bona fide hedging so that the sum of the amount of 
   initial margin deposits and premiums paid on such positions would not 
   exceed 5% of the market value of the Portfolio's net assets. Margin 
   deposits may consist of cash or securities acceptable to the broker and 
   the relevant contract market. 

       When either Portfolio purchases a futures contract, it will maintain 
   an amount of cash, cash equivalents or commercial paper or other 
   short-term high grade fixed income securities in a segregated account with 
   the Fund's custodian, so that the amount so segregated plus the amount of 
   initial margin and option premiums held in the account of its broker 
   equals the value represented by the futures contract, as reflected by its 
   daily settlement price, thereby ensuring that the use of such futures 
   contract is unleveraged. It is not anticipated that transactions in 
   futures contracts will have the effect of increasing portfolio turnover. 

   
       Reference is made to the Statement of Additional Information for further
   information on financial futures contracts. 
     
       The Fund may invest in a variety of instruments which may be
   characterized as "Derivative Securities." The Fund may invest in Municipal
   Bonds 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
     












                                       21
   <PAGE> 24 

   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. 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 exempt
   securities increase or decrease in response to such changes. As a result, the
   market values of such securities will generally be more volatile than the
   market values of fixed-rate tax exempt securities. To seek to limit the
   volatility of these securities, the Fund may purchase inverse floating
   obligations with shorter term maturities or which contain limitations on the
   extent to which the interest rate may vary. The Manager believes that indexed
   and inverse floating obligations represent a flexible portfolio management
   instrument for the Fund which allows the Manager to vary the degree of
   investment leverage relatively efficiently under different market conditions.
   Certain investments in such obligations may be illiquid. The Fund may not
   invest in such illiquid obligations if such investments, together with other
   illiquid investments, would exceed 10% of the Fund's net assets.
 

   Investment Restrictions 

       The Fund has adopted a number of restrictions and policies relating to
   the investment of its assets and its activities, which are fundamental
   policies of the Fund and may not be changed without the approval of the
   holders of a majority of the Fund's outstanding voting securities (including
   a majority of the shares of each Portfolio). One such restriction prohibits
   the Fund from entering into a repurchase agreement if, as a result thereof,
   more than 10% of the total assets of any Portfolio (taken at market value at
   the time of each investment) would be subject to repurchase agreements
   maturing in more than seven days. Investors are referred to the Statement of
   Additional Information for a complete description of such restrictions and
   policies.
   

       The Board of Directors of the Fund, at a meeting held on August 4, 1994,
   approved certain changes to the fundamental and non-fundamental investment
   restrictions of the Fund. These changes were proposed in connection with the
   creation of a set of standard fundamental and non-fundamental investment
   restrictions that would be adopted, subject to shareholder approval, by all
   of the non-money market mutual funds advised by MLAM or FAM. The proposed
   uniform investment restrictions are designed to provide each of these funds,
   including the Fund, with as much investment flexibility as possible under the
   Investment Company Act and applicable state securities regulations, help
   promote operational efficiencies and facilitate monitoring of compliance. The
   investment objectives and policies of the Fund will be unaffected by the
   adoption of the proposed investment restrictions.

    

       The full text of the proposed investment restrictions is set forth under
   "Investment Objective and Policies-Proposed Uniform Investment Restrictions"
   in the Statement of Additional Information. Shareholders of the Fund are
   currently considering whether to approve the proposed revised investment
   restrictions. If such shareholder approval is obtained, the Fund's current
   investment restrictions will be replaced by the proposed restrictions, and
   the Fund's Prospectus and Statement of Additional Information will be
   supplemented to reflect such change.

   New Jersey 08543-9011. FAM or MLAM acts as the Investment Adviser for over
   100 other investment companies. As of August 31, 1994, the Investment Adviser
   and MLAM had a total of approximately $165.7 billion in investment company
   and other portfolio assets under management, including accounts of certain
   affiliates of the investment adviser.
 
       FAM, subject to the general supervision of the Fund's Board of 
   Directors, renders investment advice to the Fund and is responsible for 
   the overall management of the Fund's business affairs. The responsibility 
   for making decisions to buy, sell or hold a particular security rests with 
   FAM. For the year ended June 30, 1994, FAM received in fees from the Fund 
   $22,860,647, of which $11,040,540 was received with respect to the Insured 
   Portfolio (representing 0.36% of its average net assets), $8,514,268 was 
   received with respect to the National Portfolio (representing 0.48% of its 
   average net assets) and $3,305,839 was received with respect to the 
   Limited Maturity Portfolio (representing 0.33% of its average net assets). 

       The Investment Advisory Agreement obligates each Portfolio to pay certain
   expenses incurred in its operation and a portion of the Fund's general
   administrative expenses allocated on the basis of the asset size of the
   respective Portfolios. The Fund's total expenses for the year ended June 30,
   1994 were $37,728,533, of which $19,914,627 was attributable to the Insured
   Portfolio (representing .42% of average net assets for Class A shares and
   1.17% of average net assets for Class B shares), $13,322,352 was attributable
   to the National Portfolio (representing .55% of average net assets for Class
   A shares and 1.30% of average net assets for Class B shares) and $4,491,554
   was attributable to the Limited Maturity Portfolio (representing 0.40% of
   average net assets for Class A shares and 0.76% of average net assets for
   Class B shares); no Class C shares or Class D shares had been issued that
   year. FAM was not required to reduce its fee or reimburse any of the Fund's
   expenses for the 1994 fiscal year.

       Vincent Giordano has served as the Fund's Portfolio Manager since 
   1977, and is primarily responsible for the Fund's day-to-day management. 
   He has served as a Senior Vice President of the Investment Adviser and 
   MLAM since 1984, and as Vice President from 1980 to 1984.

   *Interested person, as defined in the Investment Company Act of 1940, of 
   the Fund. 

                               PURCHASE OF SHARES 
   
       Each Portfolio offers its shares in four classes at a public offering 
   price equal to the net asset value plus varying sales charges as set forth 
   below. Merrill Lynch Funds Distributor, Inc. (the "Distributor"), an 
   affiliate of both the Investment Adviser and Merrill Lynch, acts as the 
   Distributor of the shares. Class C shares of the Limited Maturity 
   Portfolio are offered only through the Exchange Privilege. See p. 42. 

       Shares may be purchased directly from the Distributor or from other 
   securities dealers, including Merrill Lynch, with whom the Distributor has 
   entered into selected dealer agreements; however, 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. The Fund is 
   offering shares in four classes of its Portfolios 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 (the "initial 
   sales charge alternative") or on a deferred basis depending upon the 
   class of shares selected by the investor under the Merrill Lynch Select 
   Pricing SM System, as described below. Net asset value per share will be 
   determined in the manner set forth under "Net Asset Value." The minimum 
   initial purchase in each Portfolio is $1,000 and the minimum subsequent 
   purchase in each Portfolio is $50. Merrill Lynch may charge its customers 
   an administrative fee (currently $4.85) to confirm a sale of shares. 
    
       Because retirement plans qualified under Section 401 of the Internal 
   Revenue Code will be unable to benefit from the tax-exempt dividends of 
   the Fund, the shares of the Fund may not be suitable investments for such 
   retirement plans. 
   
       Each of the Portfolios 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 he 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 
   shares are sold to investors choosing the initial sales charge alternative 
   and shares of Class B and Class C shares are sold to investors choosing 
   the deferred sales charge alternatives. Class C shares of the Limited 
   Maturity Portfolio are available only through the Exchange Privilege and 
   may not be purchased except through exchange of Class C shares of another 
   Portfolio or another Fund. 

       Investors should determine whether under their particular 
   circumstances it is more advantageous to incur the initial sales charge or 
   to have the initial purchase price invested with the Portfolio with the 
   investment thereafter being subject to a contingent deferred sales charge 
   and ongoing distribution 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 8. Each Class A, Class B, Class C 
   and Class D share of a Portfolio represents identical interests in the 
   Portfolio and has the same rights, except that Class B, Class C and Class 
   D shares bear the expenses of the ongoing account maintenance fees, and 
   Class B and Class C shares bear the expenses of the ongoing distribution 
   fees and the additional incremental transfer agency costs resulting from 
   the deferred sales charge arrangements. The deferred sales charges and 
   account maintenance fees that are imposed on Class B and Class C shares, 
   as well as the account maintenance fees that are imposed on Class D 
   shares, will be imposed directly against those classes and not against all 
   assets of the Fund and, accordingly, such charges will not affect the net 
   asset value of any other class 
   





                                       24

   or have any impact on investors choosing another sales charge option.
   Dividends paid by a Portfolio 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.




   
       The following tables set forth a summary of the distribution 
   arrangements for each class of shares under the Merrill Lynch Select 
   Pricing(SM) System.

   (1) Initial sales charges are imposed at the time of purchase as a 
       percentage of the offering price. CDSCs may be imposed if the 
       redemption occurs within the applicable CDSC time period. The charge 
       will be assessed on an amount equal to the lesser of the proceeds of 
       redemption or the cost of the shares being redeemed.
   (2) Offered only to eligible investors. See "Initial Sales Charge 
       Alternatives-Class A and Class D Shares-Eligible Class A Investors."
   (3) Reduced for purchases of $25,000 or more for the Insured and National 
       Portfolios. Reduced for purchases of $100,000 or more for Limited 
       Maturity Portfolio. Class A and Class D share purchases of $1,000,000 
       or more will not be subject to an initial sales charge but instead will 
       be subject to a 1.0% CDSC for one year.
   (4) The conversion period for dividend reinvestment shares is modified. 
       Also, Class B shares of certain other MLAM-advised mutual funds into 
       which exchanges may be made have a eight-year conversion period. If 
       Class B shares of a Portfolio 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. 
   (5) Class C shares of the Limited Maturity Portfolio are offered only 
       through the Exchange Privilege. See p. 42.

   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 initial sales charges, computed as indicated below, are reduced on 
   larger purchases. The Distributor may reallow discounts to securities 
   dealers with whom it has agreements and retain the balance over such 
   discount. At times the Distributor may reallow the entire sales charge to 
   selected dealers, in which case such dealers may be deemed to be 
   underwriters within the meaning of the Securities Act of 1933 and subject 
   to liability as such. The Distributor will retain the entire sales charge 
   on orders placed directly with it. 

       The public offering price of Class A and Class D shares of the 
   Portfolios, for purchasers choosing the initial sales charge alternative, 
   is the next determined net asset value plus varying sales charges (i.e., 
   sales loads), as set forth below:

    * Rounded to the nearest one-hundredth percent. 
   ** Class A and Class D purchases of $1,000,000 or more made on or after 
      October 21, 1994 will be subject to a CDSC of 1% for the Insured and 
      National Portfolios and 0.20% for the Limited Maturity Portfolio, if 
      the shares are redeemed within one year after purchase. Class A 
      purchases made prior to October 21, 1994 may be subject to a CDSC if the 
      shares are redeemed within one year of purchase at the following rates: 
      .75% on purchases of $1,000,000 to $2,500,000; .40% on purchases of 
      $2,500,001 to $3,500,000; .25% on purchases of $3,500,001 to 
      $5,000,000; and .20% on purchases of more than $5,000,000 for the Insured
      Portfolio and National Portfolio in lieu of paying an initial sales 
      charge. Class A purchases of the Limited Maturity Portfolio made prior to
      October 21, 1994 may be subject to a CDSC of 0.20% on purchases of more
      than $1,000,000 if the shares are redeemed within one year of purchase
      in lieu of paying the initial sales charge. 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.


    
   
       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 shares of the Fund will receive a concession equal to most of the 
   sales charge, they may be deemed to be underwriters under the Securities 
   Act of 1933, as amended (the "Securities Act"). During the fiscal year 
   ended June 30, 1994, the Insured Portfolio, the National Portfolio and the 
   Limited Maturity Portfolio sold 33,131,876, 8,490,063 and 37,619,639,  
   Class A shares respectively, for aggregate net proceeds of $280,935,110, 
   $92,184,282 and $375,440,124, respectively. The gross sales charges for 
   the sale of Class A shares of the Insured Portfolio, the National 
   Portfolio and the Limited Maturity Portfolio for that year were 
   $3,435,864, of which $343,837 and $3,092,027 were received by the 
   Distributor and Merrill Lynch, respectively. For the fiscal year ended 
   June 30, 1994, the Distributor received CDSCs of $36,923 (in the case of 
   the National Portfolio), $45,329 (in the case of the Insured Portfolio) 
   and $93,556 (in the case of Limited Maturity Portfolio), all of which were 
   paid to Merrill Lynch, with respect to redemption within one year of 
   purchase of Class A shares purchased subject to front-end sales charge 
   waivers.
    

       Eligible Class A Investors. Class A shares are offered to a limited 
   group of investors and also will be issued upon reinvestment of dividends 
   from outstanding Class A shares. Investors that currently own Class A 
   shares in a shareholder account, including participants in the Merrill 
   Lynch Blueprint SM program, are entitled to purchase additional Class A 
   shares in that account. Class A shares are available at net asset value to 
   corporate warranty insurance reserve fund programs provided that the 
   program has $3 million or more initially invested in MLAM-advised mutual 
   funds. Also eligible to purchase Class A shares at net asset value are 
   participants in certain investment programs, including TMA SM Managed 
   Trusts to which Merrill Lynch Trust Company provides discretionary trustee 
   services and certain purchases made in connection with the Merrill Lynch 
   Mutual Fund Adviser program. In addition, Class A shares will be offered 
   at net asset value to  Merrill Lynch & Co., Inc. and its subsidiaries and 
   their directors and employees and to members of the Boards of MLAM-advised 
   investment companies, including the Fund. Certain persons who acquired 
   shares of certain MLAM-advised 



                                       28
   <PAGE> 31 
    

   closed-end funds who wish to reinvest the net proceeds from a sale of their
   closed-end fund shares of common stock in shares of the Fund also may
   purchase Class A shares of the Fund if certain conditions set forth in the
   Statement of Additional Information are met. For example, Class A shares of
   the Fund and certain other MLAM-advised mutual funds are offered at net asset
   value to shareholders of Merrill Lynch Senior Floating Rate Fund, Inc. who
   wish to reinvest the net proceeds from a sale of certain of their shares of
   common stock of Merrill Lynch Senior Floating Rate Fund, Inc. in shares of
   such funds.

    
       As to purchase orders received by selected dealers prior to the close 
   of the New York Stock Exchange, which includes orders received after the 
   close on the previous day, the applicable offering price will be based on 
   the net asset value determined on the day the order is placed with the 
   Distributor, provided the order is received by the Distributor prior to 
   4:30 P.M., New York City time, on that day. Any order may be rejected by 
   the Distributor or the Fund. Neither the Distributor nor the dealers are 
   permitted to withhold placing orders to benefit themselves by a price 
   change. The Fund reserves the right to suspend the sale of its shares to 
   the public in response to conditions in the Municipal Bond markets, or 
   otherwise. 

       Payment by Wire. To purchase shares by wiring Federal Funds, payment 
   should be wired to The Bank of New York, New York City. Shareholders 
   should give their financial institutions the following wiring 
   instructions, ABA #021000018, DDA #902233, Financial Data Services, Inc. 
   For all communications regarding existing accounts, please indicate the 
   name of the Portfolio, the shareholder's account number, and the 
   shareholder's name. Instructions for new accounts should specify name, 
   address and social security number of each person in whose name the shares 
   are to be registered and the name of the Portfolio. Failure to submit the 
   required information may delay investment. 

       If Federal Funds are received by the Transfer Agent by 11:00 A.M., 
   shares of the Portfolio will be issued that day based upon the net asset 
   value of the Portfolio determined as of the close of regular trading on 
   the New York Stock Exchange that day. Shares begin accruing dividends so 
   long as they are issued and outstanding. Shares are issued and outstanding 
   as of the settlement date of a purchase order to the settlement date of a 
   redemption order. Since purchases of shares of the Fund are normally 
   effected on the basis of a five-business-day settlement procedure, this 
   method of payment provides an expeditious method of investing in the 
   Portfolios of the Fund. Many of the Municipal Bonds in which a Portfolio 
   invests do not trade on the basis of one-day settlements, and, since the 
   only municipal securities that a Portfolio may acquire on a one-day 
   settlement offer lower yields, if a substantial amount is invested by wire 
   transfer this may have the effect of decreasing the yield in that 
   Portfolio. The Fund is not responsible for delays in the wiring system. 

       The minimum purchase for payment by wire is $1,000, except that the 
   minimum purchase for payment by wire for new accounts is $5,000. 

       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."

      Class D shares are also offered at net asset value without sales charge to
   an investor who has a business relationship with a financial consultant 
   if certain conditions set forth in the Statement of Additional Information
   are met. Class D shares may be offered at net asset value in connection with
   the acquisition of assets of other investment companies.

       Class D shares are offered with reduced sales charges and, in certain 
   circumstances, at net asset value, to participants in the Merrill Lynch 
   Blueprint SM Program.
    
       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 of the Insured and 
   National Portfolios are subject to a four year CDSC and Class B shares of 
   the Limited Maturity Portfolio are subject to a one 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 relevant Portfolio and thereafter will be be subject to lower 
   continuing fees. Class C shares of the Limited Maturity Portfolio are 
   available only through the Exchange Privilege. See "Conversion of Class B 
   Shares to Class D Shares" below. Both Class B and Class C shares of each 
   Portfolio are subject to an account maintenance fee of 0.25% (in the case 
   of the National and Insured Portfolios) and 0.15% (in the case of the 
   Limited Maturity Portfolio) of net assets. Class B and Class C shares of 
   the Insured and National Portfolios are subject to distribution fees 0.50% 
   and 0.55%, respectively of the net assets. Class B and Class C shares of 
   the Limited Maturity portfolio are subject to a distribution fee of 0.20%. 
   See "Distribution Plans." The proceeds from 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" below. 

       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 its 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 of a Portfolio shares will 
   convert automatically into Class D shares of that Portfolio, which are 
   subject to an account maintenance fee but 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.

      Imposition of the CDSC and the distribution fee on Class B and Class C 
   shares is limited by the NASD asset-based sales charge rule. See 
   "Limitations on the Payment of Deferred Sales Charges" below. The 
   proceeds from the ongoing account maintenance fee are used to compensate 
   Merrill Lynch for providing continuing

   account maintenance activities. Class B shareholders on 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 Charge-Class B Shares. Class B shares of the 
   Insured and National Portfolios redeemed within four years of purchase for 
   the National and Insured Portfolios and Class B shares of the Limited 
   Maturity Portfolio redeemed within one year 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 the redemption of shares received upon the reinvestment of 
   dividends or capital gains distributions.

       The following table sets forth the rates of the contingent deferred 
   sales charge on Class B shares applicable for the period starting October 
   21, 1994:

       In determining whether a contingent deferred sales charge is 
   applicable to a redemption, the calculation will be made in a manner that 
   results in the lowest possible applicable rate being charged. Therefore, 
   with respect to the Insured and National Portfolios, 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 applicable four-year period. It will be 
   assumed, with respect to the Limited Maturity Portfolio, that the 
   redemption is of shares held for over one year or shares acquired pursuant 
   to reinvestment of dividends or distributions. 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 
   of the Insured Portfolio 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 








                                       31
   <PAGE> 34 

   investor makes his or her first redemption of 50 shares (proceeds of
   $600), 10 shares will not be subject to charge 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 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 Internal Revenue Code) of a
   shareholder.

       The Class B CDSC also is waived on redemptions of shares placing 
   purchase orders through Merrill Lynch Blueprint SM Program. See 
   "Shareholder Services-Merrill Lynch Blueprint Program." Additional 
   information concerning the waiver of the Class B CDSC is set forth in the 
   Statement of Additional Information. 

       For the fiscal year ended June 30, 1994, the Distributor received 
   $2,378,916 in contingent deferred sales charges, amounting to $1,469,123, 
   $718,890 and $190,903 in the Insured, National and Limited Maturity 
   Portfolios, respectively.

       Contingent Deferred Sales Charges-Class C Shares. Class C shares which 
   are redeemed within one year of purchase may be subject to a 1.0% CDSC 
   charged as a percentage of the dollar amount subject thereto. The charge 
   will be assessed on an amount equal to the lesser of the proceeds of 
   redemption or the cost of the shares being redeemed. Accordingly, no Class 
   C CDSC will be imposed on increases in net asset value above the initial 
   purchase price. In addition, no Class C CDSC will be assessed on shares 
   derived from reinvestment of dividends or capital gains distributions.

       The following table sets forth the rates of the contingent deferred 
   sales charge on the Class C shares of the Insured, National and Limited 
   Maturity Portfolios:

                                                                             Contingent Deferred

       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 of a Portfolio will 
   be converted automatically into Class D shares of the relevant Portfolio. 
   Class D shares are subject to an ongoing account maintenance fee of 0.25% 
   (in the case of Insured Portfolio and National Portfolio) and 0.10% (in 
   the case of the Limited Maturity Portfolio) 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.



    









                                       32
   <PAGE> 35 
   

       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 exchange will apply, and the holding period for the 
   shares exchanged will be tacked onto the holding period for the shares 
   acquired.
     
   Distribution Plans

       The Fund has adopted separate distribution plans for Class B, Class C 
   and Class D shares pursuant to Rule 12b-1 under the Investment Company Act 
   (each a "Distribution Plan") with respect to the account maintenance 
   and/or distribution fees paid by the Fund to the Distributor with respect 
   to such classes. The Class B and Class C Distribution Plans provide for 
   the payment of account maintenance fees and distribution fees, and the 
   Class D Distribution Plan provides for the payment of account maintenance 
   fees.
   
       The Distribution Plans for Class B, Class C and Class D shares each 
   provide that the Fund pays the Distributor an account maintenance fee
   relating to the shares of the relevant class of a Portfolio, accrued daily
   and paid monthly, at the annual rate of 0.25% (in the case of the Class B,
   Class C and Class D shares of the Insured Portfolio and the National
   Portfolio) and 0.15% (in the case of Class B and Class C shares of the
   Limited Maturity) and 0.10% (in the case of the Class D shares of the Limited
   Maturity Portfolio) of the average daily net assets of the Portfolio
   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 of a Portfolio, accrued daily and paid monthly, at the
   annual rate of 0.50% and 0.55% for the Class B and Class C shares,
   respectively, of the the Insured and National Portfolios and 0.20% for the
   Class B and Class C shares of the Limited Maturity Portfolio of the average
   daily net assets of the Portfolio 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
   Portfolio. 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




    










                                       33
   <PAGE> 36 
   
   
   
   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.

       

      Prior to July 6, 1993, the Fund paid the Distributor an ongoing
   distribution fee, accrued daily and paid monthly, at the annual rate of 0.75%
   (in the case of the Insured Portfolio and National Portfolio) and 0.35% (in
   the case of the Limited Maturity Portfolio) of the average daily net assets
   of the Class B shares of the respective Portfolio's (the "Prior Plan") to
   compensate the Distributor and Merrill Lynch for providing account
   maintenance and distribution-related activities and services to Class B
   shareholders. The fee rate payable and the services provided under the Prior
   Plan are identical to the aggregate fee rate payable and the services
   provided under the Distribution Plan, the difference being that the account
   maintenance and distribution services have been unbundled. For the fiscal
   year ended June 30, 1994, the Fund paid account maintenance and distribution
   fees of $6,980,635 with respect to the Class B shares of the Insured
   Portfolio, account maintenance and distribution fees of $3,496,610 with
   respect to the Class B shares of the National Portfolio, and account
   maintenance and distribution fees of $466,701 with respect to Class B shares
   of the Limited Maturity Portfolio. Substantially all of the payments received
   by the Distributor under the Distribution Plan was paid to Merrill Lynch for
   providing distribution-related services in connection with the Class B
   shares. The Distribution Plan is designed to permit an investor to purchase
   Class B shares through dealers without assessment of a front-end sales load
   and at the same time permit the dealer to compensate its financial
   consultants in connection with the sale of the Class B shares. In this
   regard, the purpose and function of the distribution fee and the CDSC are the
   same as those of the initial sales charge with respect to the Class A share
   of the Portfolio in that the deferred sales charges provide for the financing
   of the distribution of such Portfolio's Class B shares. 
   

       For the year ended June 30, 1994, the Fund paid the Distributor account
   maintenance fees of $3,625,758 and distribution fees of $7,318,188 under the
   Class B Distribution Plan. The Fund did not begin to offer shares of Class C
   or Class D publicly until the date of this Prospectus. Accordingly, no
   payments have been made pursuant to the Class C or Class D Distribution Plans
   prior to the date of this Prospectus.

      The payments under the Distribution Plans are based on a percentage of
   average daily net assets attributable to the relevant shares regardless of
   the amount of expenses incurred and, accordingly, distribution-related
   revenues from Distribution Plans may be more or less than
   distribution-related expenses. Information with respect to the
   distribution-related revenues and expenses incurred by the Distributor and
   Merrill Lynch with respect to the Class B shares 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 account
   maintenance fees, the distribution fees, the contingent deferred sales
   charges and certain other related revenues, and expenses consist of financial
   consultant compensation, branch office and regional operation center selling
   and transaction procession 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, the contingent deferred sales charges and expenses
   consist of financial consultant compensation. As of December 31, 1993, the
   last date for which fully allocated accrual data is available, the fully
   allocated accrual expenses incurred by the Distributor and Merrill Lynch
   since October 24, 1988 with respect to Class B shares of the Insured
   Portfolio exceeded revenues for that period by $6,929,000 (0.71% of the
   Insured Portfolio's net assets at that date), and the fully allocated accrual
   expenses incurred by the Distributor and Merrill Lynch during


    








                                       34
   <PAGE> 37 
   

   that period with respect to Class B shares of the National Portfolio
   exceeded revenues for that period by $4,235,000 (0.85% of the National
   Portfolio's net assets at that date). The fully allocated accrual expenses
   incurred by the Distributor and Merrill Lynch during the period from November
   2, 1992 to December 31, 1993 with respect to Class B shares of the Limited
   Maturity Portfolio exceeded revenues by $527,000 (0.37% of the Limited
   Maturity Portfolio's net assets at that date). As of December 31, 1993,
   direct cash revenues received with respect to the Insured Portfolio for the
   period since October 24, 1988 exceeded direct cash expenses incurred with
   respect to the Insured Portfolio by $10,889,786 (1.17%) of the Insured
   Portfolio's net assets at that date), and direct cash revenues incurred with
   respect to the National Portfolio for that period exceeded direct cash
   expenses received with respect to the National Portfolio by $4,229,610 (0.85%
   of the National Portfolio's net assets at that date). The direct cash
   expenses incurred with respect to the Limited Maturity Portfolio for the
   period from November 2, 1992 to December 31, 1993 exceeded direct cash
   revenues received with respect to the Limited Maturity Portfolio by $1,669
   (.001% of the Limited Maturity Portfolio's net asset value at December 31,
   1993). As of June 30, 1994, direct cash revenues received with respect to the
   Insured Portfolio for the period since October 24, 1988 exceeded direct cash
   expenses incurred with respect to the Insured Portfolio by $13,801,624 (1.50%
   of the Insured Portfolio's net assets at that date), and direct cash revenues
   received with respect to the National Portfolio for the period exceeded
   direct cash expenses incurred with respect to the National Portfolio by
   $5,502,600 (1.20% of the National Portfolio's net assets at that date). As of
   June 30, 1994, direct cash revenues received with respect to the Limited
   Maturity Portfolio for the period since November 2, 1992 exceeded direct cash
   expenses incurred with respect to the Limited Maturity Portfolio by $259,536
   (.17% of the Limited Maturity Portfolio's net assets at that date).

       The Fund has no obligation with respect to distribution and/or account 
   maintenance related expenses incurred by the Distributor and Merrill Lynch 
   in connection with the Class B, Class C and Class D shares, and there is 
   no assurance that the Board of Directors of the Fund will approve the 
   continuation 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 Directors will be asked to 
   take into consideration expenses incurred in connection with the account 
   maintenance and/or distribution of each Class of a Portfolio separately. 
   The initial sales charges, the account maintenance fee, the distribution 
   fee and/or the CDSCs received with respect to the one class of a Portfolio 
   will not be used to subsidize the sale of shares of another class of the 
   same Portfolio or of any class of another Portfolio. 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 to 
   Class D Shares." 
    
   Limitations on the Payment of Deferred Sales Charges 
   
       The maximum sales charge rule in the Rules of Fair Practice of the 
   National Association of Securities Dealers, Inc. ("NASD") imposes a 
   limitation on certain asset-based sales charges such as the Fund's 
   distribution fee and the CDSC borne by the Class B and Class C but not the 
   account maintenance fees. The maximum sales charge rule is applied 
   separately to each class and Portfolio. As applicable to a Portfolio, 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 of that Portfolio , computed 
   separately (defined to exclude shares issued pursuant to dividend 
   reinvestments and exchanges), plus (2) interest on the unpaid balance for 
   the respective classes, 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 



    










                                       35
   <PAGE> 38 
   
   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 charge at any time. To the 
   extent payments would exceed the voluntary maximum, the Fund will not make 
   further payments of the distribution fee with respect to Class B shares 
   and any CDSCs will be paid to the Fund rather than to the Distributor; 
   however, the Fund will continue to make payments of the account 
   maintenance fees. 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. 

                              REDEMPTION OF SHARES 

       The Fund is required to redeem for cash all shares of each Portfolio 
   upon receipt of a written request in proper form. The redemption price is 
   the net asset value per share of the Portfolio next determined after the 
   initial receipt of proper notice of redemption. Except for any contingent 
   deferred sales load 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 declared through the date of redemption. The 
   value of shares at the time of redemption may be more or less than the 
   shareholder's cost, depending on the market value of the securities held 
   by the relevant Portfolio at such time. If a shareholder redeems all of 
   the shares in his account, he will receive, in addition to the net asset 
   value of the shares redeemed, a separate check representing all dividends 
   declared but unpaid. If a shareholder redeems a portion of the shares in 
   his account, the dividends declared but unpaid on the shares redeemed will 
   be distributed on the next dividend payment date. As set forth below, 
   special procedures are available pursuant to which shareholders may redeem 
   by check. 

   Redemption 

       A shareholder wishing to redeem shares may do so by tendering the 
   shares directly to the Transfer Agent, Financial Data Services, Inc., 
   Transfer Agency Mutual Fund Operations, P.O. Box 45289, Jacksonville, 
   Florida 32232-5289. Redemption requests delivered other than by mail 
   should be delivered to Financial Data Services, Inc., Transfer Agency 
   Mutual Fund Operations, 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 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 the certificate(s) for the shares to be 
   redeemed. The notice in either event requires the signature(s) of all 
   persons in whose name(s) the shares are registered, signed exactly as 
   their name(s) appear on the Transfer Agent's register or on the 
   certificate(s), as the case may be. The signature(s) on the redemption 
   request must be guaranteed by an "eligible guarantor institution" as 
   such is defined in Rule 17Ad-15 under the Securities Exchange Act of 1934, 
   the existence and validity of which may be verified by the Transfer Agent 
   through the use of industry publications. Notarized signatures are not 
   sufficient. Examples of eligible guarantor institutions include most 
   commercial banks and other broker dealers (including for example, Merrill 
   Lynch branch offices). Information regarding other financial institutions 
   which qualify as "eligible guarantor institutions" may be obtained from 
   the Transfer Agent. In certain instances, the Transfer Agent may require
   additional documents such as, but not limited to, trust instruments, death
   certifica tes, appointments as executor or administrator, or certificates of
   corporate authority. For shareholders redeeming directly with the Transfer
   Agent, payment will be mailed within seven days of receipt of a proper notice
   of redemption.

       











                                       36
   <PAGE> 39 
   
       At various times the Fund may be requested to redeem shares of a 
   Portfolio for which it has not yet received good payment. The Fund may 
   delay or cause to be delayed the mailing of a redemption check until such 
   time, not exceeding ten days, as it has assured itself that good payment 
   (e.g., cash or certified check drawn on a United States bank) has been 
   collected for the purchase of such shares. Normally this delay will not 
   exceed 10 days. 
       
   Repurchase 
   
       The Fund will also repurchase shares of each Portfolio through a 
   shareholder's listed securities dealer. The Fund will normally accept 
   orders to repurchase shares by wire or telephone from dealers for their 
   customers at the net asset value next computed after receipt of the order 
   by the dealer, provided that the request for repurchase is received by the 
   dealer prior to the close of business on the New York Stock Exchange on 
   the day received and is received by the Fund from the dealer not later 
   than 4:30 P.M., New York City time, on the same day. Dealers have the 
   responsibility of submitting such repurchase requests to the Fund not 
   later than 4:30 P.M., New York City time, in order to obtain that day's 
   closing price. These repurchase arrangements are for the convenience of 
   shareholders and do not involve a charge by the Fund (other than any 
   applicable CDSC); however, securities dealers may impose a charge on the 
   shareholder for transmitting the notice of repurchase to the Fund. Merrill 
   Lynch may charge its customers a processing fee (currently $4.85) to 
   confirm a repurchase of shares. Redemptions directly through the Fund's 
   Transfer Agent are not subject to the processing fee. The Fund reserves 
   the right to reject any order for repurchase. The exercise of this right 
   of rejection might adversely affect shareholders seeking redemption 
   through the repurchase procedure. 
    
       For shareholders redeeming through their listed securities dealer, 
   payment for full and fractional shares will be made by the securities 
   dealer 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 

       As described in further detail in the Statement of Additional 
   Information, holders of Class A or Class D shares of any of the three 
   Portfolios who have redeemed their shares have a one-time privilege to 
   reinstate their accounts by purchasing Class A or Class D shares of the 
   same Portfolio, and class, as the case may be, in which they had invested 
   at net asset value without a sales charge up to the dollar amount 
   redeemed. 

                       DIVIDENDS, DISTRIBUTIONS AND TAXES 

   Dividends and Distributions

       The net investment income of each Portfolio is declared as dividends 
   daily as of the regular close of trading on the New York Stock Exchange 
   (currently 4:00 P.M.) immediately prior to the determination of the net 
   asset value of each Portfolio on that day. The net investment income of 
   each Portfolio 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 each Portfolio, 
   including the advisory fee and Class B account maintenance and 
   distribution fees (if applicable), are accrued daily. Dividends of net 
   investment income are declared daily and reinvested monthly in the form of 
   additional full and fractional shares of each Portfolio at net asset value 
   unless the shareholder elects to receive such dividends in cash. The per 
   share dividend distributions on each class of shares of each of the three 
   Portfolios will be reduced as a result of any account maintenance, 















                                       37
   <PAGE> 40 

   distribution and transfer agency fees applicable to that class. Shares 
   will accrue dividends as long as they are issued and outstanding. Shares 
   are issued and outstanding as of the settlement date of a purchase order 
   to the settlement date of a redemption order. 
   
       Net realized capital gains, if any, are declared and distributed to 
   the Fund's shareholders at least annually. Capital gains distributions 
   will be automatically reinvested in shares unless the shareholder elects 
   to receive such distributions in cash. 
       See "Shareholder Services-Automatic Reinvestment of Dividends and 
   Capital Gains Distributions" for information as to how to elect either 
   dividend reinvestment or cash payments. Any 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 any 
   Portfolio or received in cash. 
    
   Federal Income Taxes 

       Each Portfolio of the Fund generally will be treated as a separate 
   corporation for federal income tax purposes. Each Portfolio has qualified 
   and expects to continue to qualify for the special tax treatment afforded 
   regulated investment companies under the Internal Revenue Code of 1986, as 
   amended (the "Code"). If each Portfolio qualifies for that tax 
   treatment, it will not be subject to federal income tax on that part of 
   its net ordinary income and net realized long-term capital gains which it 
   distributes to its shareholders. 

       Each Portfolio has qualified and expects to continue to qualify to pay 
   "exempt-interest" dividends as defined in the Code. If it so qualifies, 
   dividends or any part thereof (other than any capital gain distributions) 
   paid by the Portfolio which are attributable to interest on tax-exempt 
   obligations and designated by the Portfolio as exempt-interest dividends 
   in a written notice mailed to the Portfolio's shareholders within sixty 
   days after the close of its taxable year may be treated by shareholders 
   for all purposes as items of interest excludable from their gross income 
   under Section 103(a) of the Code. The recipient of tax-exempt income is 
   required to report such income on his federal income tax return. However, 
   a shareholder is advised to consult his tax adviser with respect to 
   whether exempt-interest dividends retain the exclusion under Section 
   103(a) if such shareholder would be treated as a "substantial user" 
   under Section 147(a)(1) with respect to some or all of the tax-exempt 
   obligations held by the Portfolio. The Code provides that interest on 
   indebtedness incurred or continued to purchase or carry shares of the 
   Portfolio is not deductible to the extent attributable to exempt-interest 
   dividends. Also, any losses realized by individuals who dispose of shares 
   of the Fund within six months of their purchase are disallowed to the 
   extent of any exempt-interest dividends received with respect to such 
   shares. 

       Each Portfolio may realize capital gains, which will constitute 
   taxable income. Any distributions designated as capital gain dividends, 
   i.e., as being made from the Portfolio's net long-term capital gains 
   (whether from tax-exempt or taxable obligations) in a written notice 
   furnished annually to shareholders are taxable to shareholders as 
   long-term capital gains, regardless of a shareholder's holding period for 
   shares of the Portfolio. In addition, if, after April 30, 1993, a 
   Portfolio acquires tax-exempt obligations having market discount 
   (generally, obligations acquired for a price less than their principal 
   amount), any gain on the disposition or retirement of such obligations 
   will be treated as ordinary income to the extent of accrued market 
   discount. 

       Dividends paid by each Portfolio from its taxable income (i.e., 
   interest on money market securities) and distributions of net realized 
   short-term capital gains (whether from tax-exempt or taxable obligations) 
   are taxable to shareholders as ordinary income. 

       Some shareholders may be subject to a 31% withholding tax ("backup 
   withholding") on reportable dividends, capital gains distributions and 
   redemption payments. Backup withholding is not required with respect to 
   dividends representing "exempt-interest." Generally, shareholders 
   subject to backup withholding will be those 









                                       38
   <PAGE> 41 
   
   for whom no certified taxpayer identification number is on file with the 
   Fund or who, to the Fund's knowledge, have furnished an incorrect number. 
   When establishing an account, an investor must certify under penalties of 
   perjury that such number is correct and that he is not otherwise subject 
   to backup withholding.
    
       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.

       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. 

       Individual shareholders of the Fund may be subject to alternative 
   minimum tax to the extent the Fund holds "private activity" bonds. The 
   Fund expects that it will hold private activity bonds; however, in 
   general, an individual shareholder filing a joint return who does not have 
   any tax preference items subject to the alternative minimum tax other than 
   income received from the Fund derived from private activity bonds would 
   have to receive more than $45,000 of such income from the Fund before 
   becoming subject to the alternative minimum tax. 
   
       Exempt-interest dividends paid by the Fund, whether or not 
   attributable to private activity bonds, may increase a corporate 
   shareholder's alternative minimum taxable income. In addition, the payment 
   of exempt- interest dividends may increase a corporate shareholder's 
   liability for the environmental tax imposed on a corporation's alternative 
   minimum taxable income (computed without regard to either the alternative 
   tax net operating loss deduction or the environmental tax deduction) at a 
   rate of $12 per $10,000 (0.12%) of alternative minimum taxable income in 
   excess of $2,000,000. The tax will be imposed even if the corporation is 
   not required to pay an alternative minimum tax. 

       The foregoing is a general and abbreviated summary of the applicable 
   provisions of the Code and Treasury Regulations currently in effect. For 
   the complete provisions, reference should be made to the pertinent Code 
   sections and the Treasury Regulations promulgated thereunder. The Code and 
   these Regulations are subject to change by legislative or administrative 
   action either prospectively or retroactively. The Statement of Additional 
   Information sets forth additional information regarding other tax aspects 
   of investment in the Fund.

       Ordinary income and capital gains dividends may also be subject to 
State and local taxes.

    
    
   
   State and Local Taxes 

       Depending upon the extent of the Fund's activities in those states and 
   localities in which its offices are maintained or in which its agents or 
   independent contractors are located, the Fund may be subject to the tax 
   laws of such states or localities. In addition, the exemption of interest 
   income for federal income tax purposes does not necessarily result in 
   exemption under the income or other tax laws of any state or local taxing 
   authority. The laws of the several states and local taxing authorities 
   vary with respect to the taxation of such interest income, and each holder 
   of shares of the Fund is advised to consult his own tax adviser in that 
   regard. The Fund will report annually the percentage of interest income 
   received by each Portfolio during the preceding year on tax-exempt 
   obligations, indicating, on a state-by-state basis, the source of such 
   income.

                             PORTFOLIO TRANSACTIONS 
   
       No Portfolio has any obligation to deal with any dealer or group of 
   dealers in the execution of transactions in portfolio securities. 
   Municipal Bonds and money market securities in which each Portfolio 
   invests are traded primarily in the over-the-counter market. Where 
   possible, each Portfolio 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 Fund 
   to obtain the best net results 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, and the firm's risk in positioning the securities involved and 
   the provision of supplemental investment research by the firm. While the 
   Fund generally seeks reasonably competitive spreads or commissions, the 
   Fund will not necessarily be paying the lowest spread or commission 
   available. Municipal Bonds and money market securities are generally 
   traded on a net basis and do not normally involve either brokerage 
   commissions or transfer taxes. The cost of portfolio securities 
   transactions of each Portfolio consists primarily of dealer or underwriter 
   spreads. Under the 1940 Act, persons affiliated with the Fund, including 
   Merrill Lynch, are prohibited from dealing with the Fund as a principal in 
   the purchase and sale of securities. The Fund has obtained an exemptive 
   order permitting it to engage in certain principal transactions involving 
   high-quality short-term Municipal Bonds. In addition, the Fund may not 
   purchase Municipal Bonds from any underwriting syndicate of which Merrill 
   Lynch is a member except pursuant to procedures approved by the Board of 
   Directors which comply with rules adopted by the Securities and Exchange 
   Commission. Affiliated persons of the Fund may serve as its broker in 
   over-the-counter transactions conducted on an agency basis. 
    
                              SHAREHOLDER SERVICES 

       Each Portfolio offers a number of shareholder services designed to 
   facilitate investment in its shares at no extra cost to the investor. 
   Below is a description of these services. Full details as to each of these 
   services and copies of the various plans described below can be obtained 
   from the Fund. 

   Investment Account 
   
       Each shareholder whose account is maintained with the Transfer Agent 
   has an Investment Account and will receive a statement, at least 
   quarterly, from the Transfer Agent. These statements will serve as 
   transaction confirmations for automatic investment purchase and the 
   reinvestment of ordinary income and long-term capital gains distributions. 
   These statements will also show any other activity in the account since 
   the preceding statement. After the end of each year, shareholders will 
   receive federal income tax information regarding dividends and capital 
   gain distributions. A shareholder may make additions to his Investment 
   Account at any time by purchasing shares at the applicable public offering 
   price either through a securities dealer which has entered into a selected 
   dealers agreement with the Distributor or by mail directly to the Transfer 
   Agent, acting as agent for the Distributor. 

       Shareholders also may 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, without charge, 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 
    













                                       40
   <PAGE> 43 
   
   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. 
    
       Share certificates are issued only for full shares and only upon the 
   specific request of the shareholder. 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. 

   Automatic Investment Plan 
       
       An Automatic Investment Plan is available whereby the Transfer Agent 
   is authorized through pre-authorized checks of $50 or more to charge the 
   regular bank account of the shareholder on a monthly basis to provide 
   systematic additions of shares of the Fund to the shareholder's Investment 
   Account. Shareholders whose positions in any Portfolio of the Fund are 
   maintained in a CMA (R) account may participate in the CMA Automated 
   Investment Program, through which investments in any Portfolio of the Fund 
   may be made on a regularly scheduled basis ranging from weekly to 
   semiannually in amounts of $100 or more.

   Automatic Reinvestment of Dividends and Capital Gains Distributions 
       
       Unless specified instructions are given as to the method of payment of 
   monthly dividends and annual capital gains distributions, they will 
   automatically be reinvested in additional shares of the respective 
   Portfolio. Such reinvestment will be at the net asset value of the shares 
   of the respective Portfolio, without sales charge, as of the close of 
   business on the payable date of the dividend or distribution. Shareholders 
   may elect in writing to receive either their income dividends or capital 
   gains distributions, or both, in cash, in which event payment will be 
   mailed by the Transfer Agent as soon as practicable after the payment 
   date, which is the last day of each month. 
   
       A shareholder may at any time, by written notification to Merrill 
   Lynch if the shareholder's account is maintained with Merrill Lynch or by 
   written notification or by telephone (1-800-MER-FUND) to the Transfer 
   Agent if the shareholder's account is maintained with the Transfer Agent, 
   elect to have subsequent dividends or capital gains distributions, or 
   both, paid in cash, rather than reinvested, in which event payment will be 
   mailed on or about the payment date. Cash payments can also be directed to 
   the shareholder's bank account. No CDSC will be imposed upon redemption of 
   shares issued as a result of the automatic reinvestment of dividends or 
   capital gains distributions.

   Systematic Withdrawal Plans 

       As described in further detail in the Statement of Additional 
   Information, a holder of Class A or Class D shares of any of the three 
   Portfolios may elect to make systematic withdrawals from his or her 
   Investment Account on either a monthly or calendar quarterly basis.

   Exchange Privileges 

       Shareholders of each class of shares of a Portfolio who have held all 
   or part of their shares in the Portfolio for at least 15 days may exchange 
   their shares for shares of certain other Portfolios of the Fund, or with 
   certain other MLAM-advised mutual funds.

       Under the Merrill Lynch Select Pricing SM System, Class A 
   shareholders may exchange Class A shares of a Portfolio for Class A shares 
   of another Portfolio or a second MLAM-advised mutual fund if the 
   shareholder holds any Class A shares of the other Portfolio or second fund 
   in his account in which the exchange is made at the time of the exchange 
   or is otherwise eligible to purchase Class A shares of the other Portfolio 
   or second fund. If the Class A shareholder wants to exchange Class A 
   shares for shares of other Portfolio or a second MLAM-advised mutual fund, 
   and the shareholder does not hold Class A shares of the other Portfolio or 
   second fund in his account at that time of the exchange and is not 
   otherwise eligible to acquire Class A shares of the other Portfolio or 
   second fund, the shareholder will receive Class D shares of the other 
   Portfolio or second fund as a result of the exchange. Class D shares also 
   may be exchanged for Class A shares of another Portfolio or 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 other Portfolio or second fund.
    
       Exchanges of Class A and Class D shares are made on the basis of the 
   relative net asset values per Class A or Class D share, respectively, plus 
   an amount equal to the difference, if any, between the sales charge 
   previously paid on the Class A or Class D shares being exchanged and the 
   sales charge payable at the time of the exchange on the shares being 
   acquired.
   
       Class B, Class C and Class D shares of a Portfolio will be 
   exchangeable with shares of the same class of another Portfolio or other 
   MLAM-advised mutual funds. Class C shares of the Limited Maturity 
   Portfolio are available only through the Exchange Privilege. 

       Shares of a Portfolio which are subject to a CDSC will be 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 
   Portfolio. 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 Portfolio is "tacked" to the holding 
   period of the newly acquired shares of the other fund or Portfolio.
    
       Class A, Class B, Class C and Class D shares also will be 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 a Portfolio exercising the exchange privilege 
   will continue to be subject to the CDSC schedule applicable to that 
   Portfolio if such schedule is higher than the CDSC schedule relating to 
   the new Class B shares. In addition, Class B shares of a Portfolio 
   acquired through use of the exchange privilege will be subject to the CDSC 
   schedule applicable to that Portfolio if such schedule is higher than the 
   CDSC schedule relating to the Class B shares of the MLAM-advised mutual 
   fund from which the exchange has been made.

       Exercise of the exchange privilege is treated as a sale for Federal 
   income tax purposes. For further information, see "Shareholder Services-
   Exchange Privilege" in the Statement of Additional Information.
   
       Each Portfolio's exchange privilege is modified with respect to 
   purchases of Class A and Class D shares under the Merrill Lynch Mutual 
   Fund Adviser ("MFA") program. First, the initial allocation of assets is 
   made under the MFA program. Then, any subsequent exchange under the MFA 
   program of Class A or Class D shares of an MLAM-advised mutual fund for 
   Class A or Class D shares of a Portfolio of the Fund will be made solely 
   on the basis of the relative net asset values of the shares being 
   exchanged. Therefore, there will not be a charge for any difference 
   between the sales charge previously paid on the shares of the other 
   MLAM-advised mutual fund and the sales charge payable on the shares of the 
   Fund being acquired in the exchange under the MFA program.
    
                             ADDITIONAL INFORMATION 

   Determination of Net Asset Value 
   
       The net asset value of the shares of all classes of each Portfolio is 
   determined by FAM once daily as of 4:15 P.M., New York City time, on each 
   day that the New York Stock Exchange is open for trading immediately after 
   the declaration of dividends. The net asset value per share is computed by 
   dividing the sum of the value of the portfolio securities held by each 
   Portfolio 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 investment advisory fees payable to FAM, account 
   maintenance and/or distribution fees payable to the distributor are 
   accrued daily. 

       The per share net asset value of Class A shares of a Portfolio 
   generally will be higher than the per share net asset value of shares of 
   the other classes of that Portfolio, 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 and higher transfer agency 
   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 distribution 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 four classes of a 
   Portfolio will tend to converge immediately after the payment of dividends 
   or distributions, which will differ by approximately the amount of expense 
   accrual differentials among the classes. 
    
   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 the Class A, Class B, Class C and Class D 
   shares of the Portfolios in accordance with formulas specified by the 
   Securities and Exchange 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 


















                                       43
   <PAGE> 46 
   
   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 with respect to all shares of a Portfolio, 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 
   distribution fees, account maintenance fees and any incremental transfer 
   agency costs relating to a class of shares will be borne exclusively by 
   that class. The Fund will include performance data for all classes of 
   shares of the Portfolios in any advertisement or information including 
   performance data for such Portfolios. 

       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 charge will not be included. Actual annual or annualized 
   total return data generally will be lower than average annual total return 
   data since the average annual rates of return reflect compounding; 
   aggregate total return data generally will be higher than average annual 
   total return data since the aggregate rates of return reflect compounding 
   over a longer period of time. 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 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 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 ending June 30, 1994 for National 
   Portfolio Class A shares was 5.59% and 5.05% for Class B shares, for 
   Insured Portfolio Class A shares was 5.20% and 4.65% for Class B shares, 
   and for Limited Maturity Portfolio Class A shares was 3.89% and 3.56% for 
   Class B shares. The tax-equivalent yield for the same period (based on a 
   tax rate of 28%) for National Portfolio Class A shares was 7.76% and 7.01% 
   for the Class B shares, for Insured Portfolio Class A shares was 7.22% and 
   6.46% for the Class B shares and for Limited Maturity Portfolio Class A 
   shares was 5.40% and 4.94% for Class B 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 that of the 
   Standard & Poor's 500 Composite Stock Price Index, the Value Line 
   Composite Index, the Dow Jones Industrial Average, or performance data 
   contained in publications such as Lipper Analytical Services, Inc., 
   Morningstar Publications, Inc., Money Magazine, U.S. News & World Report, 
   Business Week, CDA Investment Technology, Inc., Forbes Magazine or Fortune 
   Magazine. As with other performance data, performance comparisons should 
   not be considered representative of the Fund's relative performance for 
   any future period.

   Rating Information 
    
    DESCRIPTIONS OF MOODY'S INVESTORS SERVICE, INC.'S MUNICIPAL BOND RATINGS 

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

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

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

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

       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.

       Conditional Rating: Bonds for which the security depends upon the 
   completion of some act or the fulfillment of some condition are rated 
   conditionally. These are bonds secured by (a) earnings of projects under 
   construction, (b) earnings of projects unseasoned in operation experience, 
   (c) rentals which begin when facilities are completed, or (d) payments to 
   which some other limiting condition attaches. Parenthetical rating denotes 
   probable credit stature upon completion of construction or elimination of 
   basis of condition. 

       Rating Refinements: Moody's may apply numerical modifiers, 1, 2 and 3 
   in each generic rating classification from Aa through B in its municipal 
   bond rating system. The modifier 1 indicates that the security ranks in 
   the higher end of its generic rating category; the modifier 2 indicates a 
   mid-range ranking; and a modifier 3 indicates that the issue ranks in the 
   lower end of its generic rating category.

   <PAGE> 48 

       Short-term Notes: The four ratings of Moody's for short-term notes are 
   MIG 1, MIG 2, MIG 3 and MIG 4. MIG 1 denotes best quality. There is 
   present strong protection by established cash flows, superior liquidity 
   support or demonstrated broad-based access to the market for refinancing; 
   MIG 2 denotes high quality. Margins of protection are ample although not 
   so large as in the preceding group; MIG 3 denotes favorable quality. All 
   security elements are accounted for but there is lacking the undeniable 
   strength of the preceding grades. Liquidity and cash flow protection may 
   be narrow and market access for refinancing is likely to be less well 
   established; MIG 4 denotes adequate quality. Protection commonly regarded 
   as required of an investment security is present and although not 
   distinctly or predominantly speculative, there is specific risk. 

                DESCRIPTIONS OF MOODY'S COMMERCIAL PAPER RATINGS

       Moody's Commercial Paper ratings are opinions of the ability to repay 
   punctually promissory obligations having an original maturity not 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. 

           Issuers rated Prime-2 (or related supporting institutions) have a 
       strong capacity for repayment of short-term promissory obligations. 

           Issuers rated Prime-3 (or related supporting institutions) have an 
       acceptable capacity for repayment of short-term promissory 
       obligations. 

           Issuers rated Not Prime do not fall within any of the Prime rating 
       categories. 

     DESCRIPTIONS OF STANDARD & POOR'S CORPORATION'S MUNICIPAL DEBT RATINGS

       A Standard & Poor's municipal debt rating is a current assessment of 
   the creditworthiness of an obligor with respect to a specific obligation. 
   This assessment may take into consideration obligors such as guarantors, 
   insurers, or lessees. 

       The debt rating is not a recommendation to purchase, sell or hold a 
   security, inasmuch as it does not comment as to market price or 
   suitability for a particular investor. 

       The ratings are based on current information furnished by the issuer 
   or obtained by Standard & Poor's from other sources Standard & Poor's 
   considers reliable. Standard & Poor's does not perform an audit in 
   connection with any rating and may, on occasion, rely on unaudited 
   financial information. The rating may be changed, suspended or withdrawn 
   as a result of changes in, or unavailability of, such information, or for 
   other circumstances.
   
       The ratings are based, in varying degrees, on the following 
   considerations: 
    
   I.   Likelihood of default-capacity and willingness of the obligor as to 
   the timely payment of interest and repayment of principal in accordance 
   with the terms of the obligation; 

   II.  Nature of and provisions of the obligation; 

   III. Protection afforded 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 creditor's rights.

     AAA        Debt rated "AAA" have the highest rating assigned by Standard
                & Poor's to a debt obligation. Capacity to pay interest and 
                repay principal is extremely strong. 

     AA         Debt rated "AA" have 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" have a strong capacity to pay interest and 
                repay principal although they are somewhat more susceptible
                to the adverse effects of changes in circumstances and 
                economic conditions than debts in higher rated categories. 
   
     BBB        Debt rated "BBB" are regarded as having an adequate capacity 
                to pay interest and repay principal. Whereas they normally 
                exhibit 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. 

     BB         Debt rated "BB," "B," "CCC" and "CC" are regarded, on 
     B          balance, as predominantly speculative with respect to capacity 
     CCC        to pay interest and repay principal in accordance with the terms
       
     CC         of the obligation. "BB" indicates the lowest degree of 
                speculation and "CC" the highest of speculation. While such 
                debts will likely have some quality and protective 
                characteristics, these are outweighed by large uncertainties or 
                major risk exposures to adverse conditions. 

     C          The rating "C" is reserved for income bonds on which no 
                interest is being paid. 

     D          Debt rated "D" is in default, and payment of interest and/or 
                repayment of principal is in arrears.


       Plus (+) or Minus (-): The ratings from "AA" to "B" may be 
   modified by the addition of a plus or minus sign to show relative standing 
   within the major rating categories. 

       Provisional Ratings: The letter "p" indicates that the rating is 
   provisional. A provisional rating assumes the successful completion of the 
   project being financed by the debt being rated and indicates that payment 
   of debt service requirements is largely or entirely dependent upon the 
   successful and timely completion of the project. This rating, however, 
   while addressing credit quality subsequent to completion of the project, 
   makes no comment on the likelihood of, or the risk of default upon failure 
   of, such completion. The investor should exercise his own judgment with 
   respect to such likelihood and risk. 

      NR           Indicates that no rating has been requested, that there is 
                   insufficient information on which to base a rating or that 
                   Standard & Poor's does not rate a particular type of 
                   obligation as a matter of policy.

    Descriptions of Standard & Poor's Corporation'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 four categories, ranging from 
   "A" for the highest quality obligations to "D" for the lowest. The 
   four categories are as follows: 
      A         Issues assigned this highest rating are regarded as having the 
                greatest capacity for timely payment. Issues in this category 
                are delineated with the numbers 1, 2 and 3 to indicate the 
                relative degree of safety. 
     A-1        This designation indicates that the degree of safety regarding 
                timely payment is very strong. 
     A-2        Capacity for timely payment on issues with this designation is 
                strong. However, the relative degree of safety is not as high as
                for issues designated "A-1." 
     A-3        Issues carrying this designation have a satisfactory 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 an adequate 
                capacity for timely payment. However, such capacity may be 
                damaged by changing conditions or short-term adversities. 
     C          This rating is assigned to short-term debt obligations with a 
                doubtful capacity for payment. 
     D          This rating indicates that the issue is either in default or is 
                expected to be in default upon maturity.

       The 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. 

          Descriptions of Standard & Poor's Corporation's Note Ratings 

       A Standard & Poor's note rating reflects the liquidity concerns and 
   market access risks unique to notes. Notes due in 3 years or less will 
   likely receive a note rating. Notes maturing beyond 3 years will most 
   likely receive a long-term debt rating. The following criteria will be 
   used in making that assessment. 
   
       - Amortization schedule (the larger the final maturity relative to 
   other maturities, the more likely it will be treated as a note). 
    
       - Source of Payment (the more dependent the issue is on the market for 
   its refinancing, the more likely it will be treated as a note). 

       Note rating symbols are as follows: 

    
     SP-1      Very strong, or strong, capacity to pay principal and interest. 
               Those issues determined to possess overwhelming safety 
               characteristics will be given a plus (+) designation. 

     SP-2      Satisfactory capacity to pay principal and interest. 

     SP-3      Speculative capacity to pay principal and interest.

   Organization of the Fund 

       The Fund, a Maryland corporation, is a diversified, open-end 
   management investment company that commenced operations on October 21, 
   1977. Prior to September 21, 1979, the Fund consisted solely of the 
   Insured Portfolio. Currently, the Fund is comprised of three separate 
   Portfolios: Insured Portfolio, National Portfolio and Limited Maturity 
   Portfolio. 
   
       The authorized capital stock of the Fund consists of 3,850,000,000 
   shares of Common Stock, divided into three series, each of which is 
   divided into four classes, having a par value of $0.10 per share. The 
   shares of Insured Portfolio Series Common Stock (500,000,000 Class A, 
   375,000,000 Class B shares, 375,000,000 Class C shares, 500,000,000 Class D 
   shares authorized), High Yield Portfolio Series Common Stock (375,000,000 
   Class A, 375,000,000 Class B shares, 375,000,000 Class C shares, 
   375,000,000 Class D shares authorized), which does business under the name 
   "National Portfolio," and Limited Maturity Portfolio Series Common Stock 
   (150,000,000 Class A, 150,000,000 Class B shares, 150,000,000 Class C 
   shares, 150,000,000 Class D shares authorized) are divided into four 
   classes, designated Class A, Class B, Class C and Class D Common Stock. 
   Each Class A, Class B, Class C and Class D share of common stock of each 
   of the Portfolios represents an interest in the same assets of such 
   Portfolio and are identical in all respects to the shares of the other 
   classes except that the 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 of shares of a Portfolio has 
   exclusive voting rights with respect to matters relating to account 
   maintenance services and distribution expenditures relative to that 
   Portfolio, as applicable. Only shares of each respective Portfolio are 
   entitled to vote on matters concerning only that Portfolio. The Fund has 
   received an order from the Securities and Exchange Commission permitting 
   the issuance and sale of multiple classes of shares of the Portfolios. The 
   Directors of the Fund may classify and reclassify the shares of the Fund 
   into additional series or classes of Common Stock at a future date. The 
   creation of additional classes would require an additional order from the 
   Securities and Exchange Commission. There is no assurance that such an 
   additional order will be issued. 

       Each issued and outstanding share is entitled to one vote and to 
   participate equally in dividends and distributions declared by the 
   respective Portfolios and in net assets of the respective Portfolios upon 
   liquidation or dissolution remaining after satisfaction of outstanding 
   liabilities, except, as noted above, the Class B, Class C and Class D 
   shares of the Portfolios bear certain expenses related to the distribution 
   of such shares. The shares of each Portfolio, when issued, will be fully 
   paid and nonassessable, have no preference, pre-emptive, conversion, 
   exchange or similar rights. Shares have the conversion rights described in 
   this Prospectus. Holders of shares of any Portfolio are entitled to redeem 
   their shares as set forth under "Redemption of Shares." Shares do not 
   have cumulative voting rights, and the holders of more than 50% of the 
   shares of the Fund voting for the election of Directors can elect all of 
   the Directors of the Fund if they choose to do so and in such event the 
   holders of the remaining shares would not be able to elect any Directors. 
   Stock certificates will be issued by the Transfer Agent only on specific 
   request. Certificates for fractional shares are not issued in any case. 
   Shareholders are entitled to redeem their shares as set forth under 
   "Redemption of Shares." 
    
   Custodian 
   
       The Bank of New York, 90 Washington Street, 12th Floor, New York, New 
   York 10286, is the Fund's custodian.

   Transfer Agent 
   
       Financial Data Services, Inc. ("FDS"), which is a wholly owned 
   subsidiary of Merrill Lynch & Co., Inc., acts as the Fund'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, FDS is responsible for the issuance, 
   transfer and redemption of shares and the opening and maintenance of 
   shareholder accounts. Pursuant to the Transfer Agency Agreement, FDS 
   receives an annual fee of $11.00 per shareholder account for Class A or 
   Class D shares of the Portfolios and $14.00 per shareholder account for 
   Class B or Class C shares of the Portfolios, and is entitled to 
   reimbursement for out-of-pocket expenses incurred by it under the Transfer 
   Agency Agreement. For the year ended June 30, 1994, the Insured, National 
   and Limited Maturity Portfolios of the Fund incurred fees of $989,990, 
   $692,712 and $195,214, respectively, pursuant to the Transfer Agency 
   Agreement.

   STATEMENT OF ADDITIONAL INFORMATION 
   -----------------------------------
   
   OCTOBER 21, 1994 

                    MERRILL LYNCH MUNICIPAL BOND FUND, INC. 
   P.O. BOX 9011, PRINCETON, NEW JERSEY 08543-9011 * PHONE NO. (609) 282-2800
    
                                   ---------- 

       Merrill Lynch Municipal Bond Fund, Inc. (the "Fund") is a 
   professionally managed, diversified, open-end investment company which 
   seeks to provide shareholders with as high a level of income exempt from 
   Federal income taxes as is consistent with the investment policies of each 
   of its Portfolios and prudent investment management. The Fund is comprised 
   of three separate Portfolios: the Insured Portfolio, the National 
   Portfolio and the Limited Maturity Portfolio, each of which invests 
   primarily in a diversified portfolio of tax-exempt Municipal Bonds, 
   principally consisting of state, municipal and public authority 
   securities. 
   
       The Fund is a series fund and is comprised of three separate 
   Portfolios. Each Portfolio is, in effect, a separate fund issuing its own 
   shares. Pursuant to the Merrill Lynch Select PricingSM System, each 
   Portfolio of the Fund offers four classes of shares, each with a different 
   combination of sales charges, ongoing fees and other features except that 
   Class C shares of the Limited Maturity Portfolio are available only 
   through the Exchange Privilege. The Merrill Lynch Select Pricing 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 and should be read in conjunction with the Prospectus of the 
   Fund (the "Prospectus") dated October 21, 1994, which has been filed 
   with the Securities and Exchange Commission and is available upon oral or 
   written request without charge. Copies of the Prospectus can be obtained 
   by calling or writing the Fund at the above telephone number or address. 
   This Statement of Additional Information has been incorporated by 
   reference into the Prospectus.

                       INVESTMENT OBJECTIVE AND POLICIES 

       Reference is made to "Investment Objective and Policies" in the 
   Prospectus for a discussion of the investment objective and policies of 
   the Fund. 
   
       At June 30, 1994, the average maturity of the Insured Portfolio, 
   National Portfolio and the Limited Maturity Portfolio was approximately 
   21.7 years, 21.5 years and 1.3 years, respectively. 
    
   INSURANCE ON PORTFOLIO SECURITIES 

       Reference is made to the discussion of the Insured Portfolio under 
   "Investment Policies of the Portfolios" in the Prospectus. As stated in 
   the Prospectus, the Fund has purchased from AMBAC Indemnity Corporation 
   ("AMBAC"), Municipal Bond Investors Assurance Corporation ("MBIA") and 
   Financial Security Assurance Inc. ("FSA") separate Mutual Fund Insurance 
   Policies (the "Policies").
   
       The Policies guarantee the payment of the principal at maturity and 
   interest on all Municipal Bonds which are purchased by the Insured 
   Portfolio at a time when they are eligible for insurance. Municipal Bonds 
   are eligible for insurance if they are, at the time of purchase by the 
   Insured Portfolio, identified separately or by category in qualitative 
   guidelines furnished by AMBAC, MBIA or FSA and are in compliance with the 
   aggregate limitations on amounts set forth in such guidelines. AMBAC, MBIA 
   and/or FSA may withdraw particular securities from the classifications of 
   securities eligible for insurance while continuing to insure previously 
   acquired bonds of such ineligible issues so long as they remain in the 
   Insured Portfolio and may limit the aggregate amount of each issue or 
   category of municipal securities thereof. The restrictions on investment 
   imposed by the eligibility requirement of the Policies may reduce the 
   yield of the Insured Portfolio. 
       
   RISK FACTORS IN TRANSACTIONS IN JUNK BONDS 
   
       The National Portfolio may invest in Municipal Bonds which are rated 
   below Baa by Moody's or below BBB by Standard & Poor's or which, in the 
   Investment Adviser's judgment, possess similar credit characteristics 
   ("junk bonds"). See "Additional Information-Rating Information" in the 
   Prospectus for additional information regarding ratings of debt 
   securities. The Investment Adviser considers the ratings assigned by 
   Standard & Poor's or Moody's as one of several factors in its independent 
   credit analysis of issuers. 
    
       Junk bonds are considered by Standard & Poor's and Moody's to have 
   varying degrees of speculative characteristics. Consequently, although 
   junk bonds 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 junk bonds will be made only when, in the judgment of the Investment 
   Adviser, such securities provide attractive total return potential 
   relative to the risk of such securities, as compared to higher quality 
   debt securities. The National Portfolio will not invest in debt securities 
   in the lowest rating categories (those rated CC or lower by Standard & 
   Poor's or Ca or lower by Moody's) unless the Investment Adviser 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 National Portfolio does not intend to purchase debt 
   securities that are in default or which the Investment Adviser believes 
   will be in default. 

       Issuers of junk bonds may be highly leveraged and may not have 
   available to them more traditional methods of financing. Therefore, the 
   risks associated with acquiring the securities of such issuers generally 
   are greater than is the case with higher rated securities. For example, 
   during an economic downturn or a sustained period of rising interest 
   rates, issuers of high yield securities may be more likely to experience 
   financial stress, 











                                       2
   <PAGE> 61 

   especially if such issuers are highly leveraged. In addition, the market 
   for high yield municipal securities is relatively new and has not 
   weathered a major economic recession, and it is unknown what effects such 
   a recession might have on such securities. During such a period, 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 junk bonds because 
   such securities may be unsecured and may be subordinated to other 
   creditors of the issuer. 

       Junk bonds frequently have call or redemption features that would 
   permit an issuer to repurchase the security from the National Portfolio. 
   If a call were exercised by the issuer during a period of declining 
   interest rates, the National Portfolio likely would have to replace such 
   called security with a lower yielding security, thus decreasing the net 
   investment income to the National Portfolio and dividends to shareholders. 

       The National Portfolio may have difficulty disposing of certain junk 
   bonds because there may be a thin trading market for such securities. 
   Because not all dealers maintain markets in all junk bonds, there is no 
   established secondary market for many of these securities, and the 
   National Portfolio anticipates that such securities could be sold only to 
   a limited number of dealers or institutional investors. To the extent that 
   a secondary trading market for junk bonds does exist, it is generally 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 National Portfolio's ability to dispose of particular issues when 
   necessary to meet its 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 National Portfolio to obtain accurate 
   market quotations for purposes of valuing its portfolio. Market quotations 
   are generally available on many junk bonds 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 junk bonds acquired 
   by the National Portfolio will be purchased upon issuance, which may 
   involve special risks because the securities so acquired are new issues. 
   In such instances the National Portfolio 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 National Portfolio 
   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 junk 
   bonds, particularly in a thinly traded market. Factors adversely affecting 
   the market value of such securities are likely to affect adversely the 
   National Portfolio's net asset value. In addition, the National Portfolio 
   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. 

   TRANSACTIONS IN FUTURES CONTRACTS 

       The National Portfolio and the Limited Maturity Portfolio 
   (collectively, the "Portfolios") may engage in the purchase and sale of 
   futures contracts on an index of municipal bonds or on U.S. Treasury 
   securities, or options on such futures contracts, for hedging purposes 
   only. The Portfolios may sell such futures contracts in anticipation of a 
   decline in the value of municipal bonds held by them or may purchase such 
   futures contracts in 














                                       3
   <PAGE> 62 

   anticipation of an increase in the cost of municipal bonds they intend to 
   acquire. The Portfolios also are authorized to purchase and sell other 
   financial futures contracts which in the opinion of management provide an 
   appropriate hedge for some or all of the Fund's portfolio securities. 

       Because of low initial margin deposits made upon the opening of a 
   futures position, futures transactions involve substantial leverage. As a 
   result, relatively small movements in the price of the futures contract 
   can result in substantial unrealized gains or losses. Because the 
   Portfolios 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 Portfolios or decreases in the price of securities the Portfolios 
   intend to acquire. Further, the Portfolios will maintain cash, cash 
   equivalents and high-grade securities with the Fund's custodian, so that 
   the amount segregated plus the initial margin equals the value represented 
   by the futures contract purchased by the Portfolios, thereby ensuring that 
   such transactions are actually unleveraged. 

       Municipal bond index futures contracts commenced trading in June 1985, 
   and it is possible that trading in such futures contracts will be less 
   liquid than that in other futures contracts. The trading of futures 
   contracts and options thereon is subject to certain market risks, such as 
   trading halts, suspensions, exchange or clearing house equipment failures, 
   government intervention or other disruptions of normal trading activity, 
   which could at times make it difficult or impossible to liquidate existing 
   positions. 

       The liquidity of the market in futures contracts may be further 
   adversely affected by "daily price fluctuation limits" established by 
   contract markets, which limit the amount of a fluctuation in the price of 
   a futures contract or option thereon 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 
   positions at prices beyond the limit. Prices of existing contracts have in 
   the past moved the daily limit on a number of consecutive trading days. 
   The Portfolios will enter into a futures position only if, in the judgment 
   of the Investment Adviser, there appears to be an actively traded market 
   for such futures contracts. 
   
       The successful use of transactions in futures contracts and options 
   thereon depends on the ability of the Investment Adviser correctly to 
   forecast the direction and extent of price movements of these instruments, 
   as well as price movements of the securities held by the Portfolios within 
   a given time frame. To the extent these price movements are not correctly 
   forecast or move in a direction opposite to that anticipated, the 
   Portfolios 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, either Portfolio's total return for such period 
   may be less than if it had not engaged in the hedging transaction. See 
   "Additional Information-Description of Financial Futures Contract" below 
   for a further discussion of the risks of futures trading. 

                        CURRENT INVESTMENT RESTRICTIONS 
    
       The Fund has adopted the following investment restrictions, none of 
   which may be changed without the approval of a majority of the Fund's 
   outstanding shares, including a majority of the shares of each Portfolio, 
   which for this purpose means the vote of (i) 67% or more of the Fund's 
   shares present at a meeting, if the holders of more than 50% of the 
   outstanding shares of the Fund are present or represented by proxy, or 
   (ii) more than 50% of the Fund's outstanding shares, whichever is less. 
   For purposes of the following restrictions, the Fund's "Permissible 
   Investments" consist of Municipal Bonds and money market securities 
   referred to in the Prospectus as "Temporary Investments." The Fund may 
   not: 













                                       4
   <PAGE> 63 

       (1) Purchase any securities other than Municipal Bonds and Temporary 
   Investments; 

       (2) Invest more than 5% of the total assets of any Portfolio (taken at 
   market value at the time of each investment) in the securities of any one 
   issuer (including repurchase agreements with any one bank or dealer) 
   except that such restrictions shall not apply to United States Government 
   or Government agency securities (for the 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 industrial 
   development bonds on behalf of a private entity as a separate issuer); 

       (3) Purchase, in connection with Temporary Investments, securities 
   (other than securities of the United States Government, its agencies and 
   instrumentalities) if, as a result of such purchase, more than 20% of the 
   total assets of any Portfolio (taken at market value) would be invested in 
   any one industry; 

       (4) Enter into a repurchase agreement if, as a result thereof, more 
   than 10% of the total assets of any Portfolio (taken at market value at 
   the time of each investment) would be subject to repurchase agreements 
   maturing in more than seven days; 

       (5) Make investments for the purpose of exercising control or 
   management; 

       (6) Purchase securities of other investment companies, except in 
   connection with a merger, consolidation, acquisition or reorganization; 

       (7) Purchase or sell real estate (provided that such restriction shall 
   not apply to Permissible Investments secured by real estate or issued by 
   companies which invest in real estate or interests therein), commodities 
   or commodity contracts (provided that such restriction shall not apply to 
   financial futures contracts), interests in oil, gas or other mineral 
   exploration or development programs; 

       (8) Purchase any securities on margin, except (a) to use short-term 
   credit necessary for clearance or purchases and sales of portfolio 
   securities and (b) to make margin payments in connection with transactions 
   in financial futures contracts; 

       (9) Make short sales of securities or maintain a short position in 
   securities or write, purchase or sell puts, calls, straddles, spreads or 
   combinations thereof (this restriction does not apply to transactions in 
   options on financial futures contracts); 

       (10) Make loans to other persons, provided that the Fund may make 
   Permissible Investments (the acquisition of Municipal Bonds or bonds, 
   debentures or other corporate debt securities which are not publicly 
   distributed is considered to be the making of a loan under the Investment 
   Company Act of 1940); 

       (11) Borrow amounts in any Portfolio in excess of 10% of the total 
   assets of such Portfolio, taken at market value, and then only from banks 
   as a temporary measure for extraordinary or emergency purposes (usually 
   only "leveraged" investment companies may borrow in excess of 5% of 
   their assets; however, the Portfolios will not borrow to increase income 
   but only to meet redemption requests which might otherwise require 
   untimely dispositions of portfolio securities); 

       (12) Mortgage, pledge, hypothecate or in any manner transfer as 
   security for indebtedness any securities owned or held by any Portfolio 
   except as may be necessary in connection with borrowings mentioned in (11) 
   above, in which case such mortgaging, pledging or hypothecating may not 
   exceed 10% of such Portfolio's total assets, taken at market value, or as 
   may be necessary in connection with transactions in financial futures 
   contracts as set forth in (8) above; 












                                       5
   <PAGE> 64 

       (13) Invest in securities with legal or contractual restrictions on 
   resale (except for repurchase agreements) or for which no readily 
   available market exists if, regarding all such securities, more than 5% of 
   the total assets of any Portfolio (taken at market value) would be 
   invested in such securities; 

       (14) Act as an underwriter of securities, except to the extent that 
   the Fund may technically be deemed an underwriter when engaged in the 
   activities described in (10) above or insofar as the Fund may be deemed an 
   underwriter under the Securities Act of 1933 in selling portfolio 
   securities; and 
   
       (15) Invest in securities of any one issuer with a record of less than 
   three years of continuous operation, including predecessors, except 
   obligations issued or guaranteed by the United States Government or its 
   agencies or Municipal Bonds (except that, in case of industrial revenue 
   bonds, this restriction shall apply to the entity supplying the revenues 
   from which the issue is to be paid), if such investments by any Portfolio 
   would exceed 5% of the value of its total assets (taken at market value). 

       Proposed Uniform Investment Restrictions. As discussed in the 
   Prospectus under "Investment Objective and Policies-Investment 
   Restrictions", the Board of Directors of the Fund has approved the 
   replacement of the Fund's existing investment restrictions with the 
   fundamental and non-fundamental investment restrictions set forth below. 
   These uniform investment restrictions have been proposed for adoption by 
   all of the non-money market mutual funds advised by the Investment Adviser 
   or its affiliate, Merrill Lynch Asset Management, L.P. ("MLAM"). The 
   investment objectives and policies of the Fund will be unaffected by the 
   adoption of the proposed investment restrictions.

       Shareholders of the Fund are currently considering whether to approve 
   the proposed revised investment restrictions. If such shareholder approval 
   is obtained, the Fund's current investment restrictions will be replaced 
   by the proposed restrictions, and the Fund's Prospectus and Statement of 
   Additional Information will be supplemented to reflect such change.

       Under the proposed fundamental investment restrictions, 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, in the 
   securities of issuers in any particular industry (excluding the U.S. 
   Government and its agencies and instrumentalities).

       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 investments in 
   government obligations, commercial paper, pass-through instruments, 
   certificates of deposit, bankers' acceptances, repurchase agreements or 
   any similar instruments shall not be deemed to be the making of a loan, 
   and except further that the Fund may lend its portfolio securities, 
   provided that the lending of portfolio securities may be made only in 
   accordance with applicable law and the guidelines set forth in the Fund's 
   Prospectus and Statement of Additional Information, as they may be amended 
   from time to time.

       6. Issue senior securities to the extent such issuance would violate 
   applicable law.












                                       6
   <PAGE> 65 

       7. Borrow money, except that (i) the Fund may borrow from banks (as 
   defined in the Investment Company Act) in amounts up to 33 1/3% of its 
   total assets (including the amount borrowed), (ii) the Fund may borrow up 
   to an additional 5% of its total assets for temporary purposes, (iii) the 
   Fund may obtain such short-term credit as may be necessary for the 
   clearance of purchases and sales of portfolio securities and (iv) the Fund 
   may purchase securities on margin to the extent permitted by applicable 
   law. The Fund may not pledge its assets other than to secure such 
   borrowings or, to the extent permitted by the Fund's investment policies 
   as set forth in its Prospectus and Statement of Additional Information, as 
   they may be amended from time to time, in connection with hedging 
   transactions, short sales, when-issued and forward commitment transactions 
   and similar investment strategies.

       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 proposed non-fundamental investment restrictions, each Fund may 
   not:

       a. Purchase securities of other investment companies, except to the 
   extent such purchases are permitted by applicable law.

       b. Make short sales of securities or maintain a short position, except 
   to the extent permitted by applicable law. The Fund currently does not 
   intend to engage in short sales, except short sales "against the box."

       c. Invest in securities which cannot be readily resold because of 
   legal or contractual restrictions or which cannot otherwise be marketed, 
   redeemed or put to the issuer or a third party, if at the time of 
   acquisition more than 15% of its total assets would be invested in such 
   securities. This restriction shall not apply to securities which mature 
   within seven days or securities which the Board of Directors of the Fund 
   has otherwise determined to be liquid pursuant to applicable law. 

       Notwithstanding the 15% limitation herein, to the extent the laws of 
   any state in which the Fund's shares are registered or qualified for sale 
   require a lower limitation, the Fund will observe such limitation. As of 
   the date hereof, therefore, the Fund will not invest more than 10% of its 
   total assets in securities which are subject to this investment 
   restriction (c).

       d. Invest in warrants if, at the time of acquisition, its investments 
   in warrants, valued at the lower of cost or market value, would exceed 5% 
   of the Fund's net assets; included within such limitation, but not to 
   exceed 2% of the Fund's net assets, are warrants which are not listed on 
   the New York Stock Exchange or American Stock Exchange or a major foreign 
   exchange. For purposes of this restriction, warrants acquired by the Fund 
   in units or attached to securities may be deemed to be without value.

       e. Invest in securities of companies having a record, together with 
   predecessors, of less than three years of continuous operation, if more 
   than 5% of the Fund's total assets would be invested in such securities. 
   This restriction shall not apply to mortgage-backed securities, 
   asset-backed securities or obligations issued or guaranteed by the U.S. 
   Government, its agencies or instrumentalities.

















                                       7

       f. Purchase or retain the securities of any issuer, if those 
   individual officers and directors of the Fund, the officers and general 
   partner of the Investment Adviser, the directors of such general partner 
   or the officers and directors of any subsidiary thereof each owning 
   beneficially more than one-half of one percent of the securities of such 
   issuer own in the aggregate more than 5% of the securities of such issuer.

       g. Invest in real estate limited partnership interests or interests in 
   oil, gas or other mineral leases, or exploration or development programs, 
   except that the Fund may invest in securities issued by companies that 
   engage in oil, gas or other mineral exploration or development activities.

       h. Write, purchase or sell puts, calls, straddles, spreads or 
   combinations thereof, except to the extent permitted in the Fund's 
   Prospectus and Statement of Additional Information, as they may be amended 
   from time to time.

       Notwithstanding fundamental investment restriction (7) above, the Fund 
   currently does not intend to borrow amounts in any Portfolio in excess of 
   10% of the total assets of such Portfolio, taken at 
   market value, and then only from banks as a temporary measure for 
   extraordinary or emergency purposes such as the redemption of Fund shares. 
   In addition, the Fund will not purchase securities while borrowings are 
   outstanding.

   ----------
   (1) Interested person, as defined in the Investment Company Act of 1940, 
   of the Fund. 
   (2) Mr. Zeikel is a director or trustee and officer, Messrs. Forbes, 
       Reilly, Ryan and West and Ms. Montgomery are directors or trustees, and 
       the officers of the Fund are officers and/or directors or trustees, of 
       certain other investment companies for which the Investment Adviser or 
       MLAM acts as investment adviser (see "Investment Advisory and Other 
       Services"). 

    
       Mr. Zeikel, a director of the Fund, and the officers of the Fund owned 
   on September 30, 1994 an aggregate of less than 1/4 of 1% of the 
   outstanding shares of Common Stock of ML & Co. 
       The Fund has an Audit Committee consisting of all of the directors of 
   the Fund who are not interested persons of the Fund. 
   
       Each director of the Fund who is not an officer or employee of ML & 
   Co. or its subsidiaries receives an annual fee of $4,000 plus $800 per 
   meeting of the Board of Directors attended and an annual fee of $2,000 for 
   serving on the Audit Committee. In addition, the Fund pays all Directors' 
   actual out-of-pocket expenses relating to attendance at meetings of the 
   Board of Directors of the Fund or of any committee thereof. Mr. West is 
   paid an additional annual fee of $1,000 for serving as Chairman of the 
   Audit Committee. For the year ended June 30, 
    












                                       9

   1994, fees and expenses paid to the unaffiliated directors of the Fund 
   aggregated $48,135. No officer or employee of ML & Co., Inc. or its 
   subsidiaries receives any compensation from the Fund for acting as a 
   director or officer of the Fund. The Fund requires no employees other than 
   its officers, all of whom are compensated by FAM or the Distributor. 
   
   INVESTMENT ADVISORY ARRANGEMENTS 
   
       Fund Asset Management, L.P. ("FAM"), a subsidiary of MLAM, an 
   indirect subsidiary of Merrill Lynch & Co., Inc., acts as the investment 
   adviser for the Fund and provides the Fund with management services. While 
   FAM is at all times subject to the direction of the Board of Directors of 
   the Fund, under the Investment Advisory Agreement, FAM is responsible for 
   the actual management of each Portfolio and constantly reviews the 
   holdings of each Portfolio in light of its own research analysis and 
   analyses from other relevant sources. The responsibility for making 
   decisions to buy, sell or hold a particular security rests with FAM. FAM 
   provides the portfolio managers for each Portfolio, who consider analyses 
   from various sources, make the necessary investment decisions and place 
   transactions accordingly. FAM is also obligated to perform certain 
   administrative and management services for the Fund and is obligated to 
   provide all the office space, facilities, equipment and personnel 
   necessary to perform its duties under the Agreement. 
   
       Securities held by the Fund may also be held by other funds for which 
   FAM or MLAM acts as an adviser or by investment advisory clients of MLAM. 
   If purchases or sales of securities for the Fund or other funds for which 
   FAM or MLAM acts as investment adviser or for their advisory clients arise 
   for consideration at or about the same time, transactions in such 
   securities will be made, insofar as feasible, for the respective funds and 
   clients in a manner deemed equitable to all. To the extent that 
   transactions on behalf of more than one client of the Investment Adviser or 
   MLAM 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. 

       Advisory Fee. As compensation for its services to the Portfolios, FAM 
   receives at the end of each month a fee with respect to each Portfolio at 
   the annual rates set forth below, which are based upon the average daily 
   value of the Fund's net assets. The rates are subject to reduction to the 
   extent that the aggregate of the average daily net assets of the three 
   combined Portfolios exceeds $250 million, $400 million, $550 million and 
   $1.5 billion, respectively. The reductions will be applicable to each 
   Portfolio regardless of size on a "uniform percentage" basis. 
   Determination of the portion of the net assets of each Portfolio to which 
   the reduced rate is applicable is made by multiplying the net assets of 
   that Portfolio by the "uniform percentages," derived by dividing the 
   amount by which the combined assets of all Portfolios exceeds the various 
   applicable breakpoints by such combined assets. In addition, although 
   under the Investment Advisory Agreement FAM is entitled to a fee with 
   respect to the Insured Portfolio at an annual rate of 0.375% when the 
   Fund's aggregate net assets exceed $1.5 billion, as reflected in the table 
   below, FAM has agreed to waive such fee in excess of an annual rate of 
   0.35%.

       At the date of this Statement of Additional Information, the only 
   state which imposes limitations on the expenses of the Fund is the State 
   of California. California's annual expense limitations require that FAM 
   reimburse each Portfolio for advisory fees received by it from the Fund, 
   to the extent that such Portfolio's aggregate ordinary operating expenses 
   (excluding interest, taxes, brokerage fees and commissions, extraordinary 
   charges such as litigation costs and a percentage of distribution fees) 
   exceed in any fiscal year 2.5% of the Portfolio's first $30,000,000 of 
   average net assets, 2.0% of the next $70,000,000 of its average net assets 
   and 1.5% of the remaining net assets. No fee payment will be made to FAM 
   with respect to any Portfolio during any fiscal year which will cause the 
   expenses of such Portfolio to exceed the pro rata expense limitation 
   applicable to such Portfolio at the time of such payment. 

       For the year ended June 30, 1992, FAM received $9,530,756 from the 
   Insured Portfolio, $7,118,326 from the National Portfolio and $1,571,887 
   from the Limited Maturity Portfolio as advisory fees. For the year ended 
   June 30, 1993, FAM received $10,497,116 from the Insured Portfolio, 
   $7,817,631 from the National Portfolio and $2,526,397 from the Limited 
   Maturity Portfolio as advisory fees. For the year ended June 30, 1994, FAM 
   received $11,040,540 from the Insured Portfolio, $8,514,268 from the 
   National Portfolio and $3,305,839 from the Limited Maturity Portfolio as 
   advisory fees. 

       Payment of Expenses. The Investment Advisory Agreement obligates FAM 
   to provide investment advisory services and to pay all compensation of and 
   furnish office space for officers and employees of the Fund connected with 
   economic research, investment research, trading and investment management 
   of the Fund, as well as the fees of all directors of the Fund who are 
   affiliated persons of Merrill Lynch & Co., Inc. or any of its 
   subsidiaries. Each Portfolio pays all other expenses incurred in its 
   operation and a portion of the Fund's general administrative expenses 
   allocated on the basis of the asset size of the respective Portfolios. 
   Expenses that will be borne directly by the Portfolios include redemption 
   expenses, expenses of portfolio transactions, shareholder servicing costs, 
   portfolio insurance maintained and paid by the Insured Portfolio, expenses 
   of registering the shares under Federal and state securities laws, pricing 
   costs (including the daily calculation of net asset value), interest, 
   certain taxes, charges of the Custodian and Transfer Agent and other 
   expenses attributable to a particular Portfolio. Expenses which will be 
   allocated on the basis of the size of the respective Portfolios include 
   directors' fees, legal expenses, state franchise taxes, auditing services, 
   costs of printing proxies, stock certificates, shareholder reports and 
   prospectuses (except to the extent paid by the Distributor), Securities 
   and Exchange Commission fees, accounting costs and other expenses properly 
   payable by the Fund and allocable on the basis of the size of the 
   respective Portfolios. Accounting services are provided for the Fund by 
   FAM, and the Fund reimburses FAM for its costs in connection with such 
   services. During the year ended June 30, 1994, the Fund reimbursed FAM 
   $414,293 for such services. Depending upon the nature of a lawsuit, 
   litigation costs may be directly applicable to the Portfolios or allocated 
   on the basis of the size of the respective Portfolios. The Board of 
   Directors has determined that this is an appropriate method of allocation 
   of expenses. As required by

   the Distribution Agreement, the Distributor will pay certain of the 
   expenses of each Portfolio incurred in connection with the offering of 
   shares of each Portfolio, including the expense of printing the 
   prospectuses used in connection with the continuous offering of shares by 
   each Portfolio. See "Purchase of Shares-Distribution Agreement" in the 
   Prospectus. 
    
       Duration and Termination. Unless earlier terminated as described 
   below, the Investment Advisory Agreement will continue in effect from year 
   to year if approved annually (a) by the Board of Directors of the Fund or 
   by a majority of the outstanding voting shares of each Portfolio and (b) 
   by a majority of the Directors who are not parties to such contract or 
   interested persons (as defined in the Investment Company Act of 1940) of 
   any such party. Such contract terminates upon assignment and may be 
   terminated without penalty on 60 days' written notice at the option of 
   either party thereto or by the vote of the shareholders of the Fund. 

       If the shareholders of any Portfolio fail to approve the continuance 
   of the Investment Advisory Agreement, the Investment Advisory Agreement 
   will continue in effect as to any other Portfolio if the shareholders of 
   such Portfolio have approved the contract. 

                                NET ASSET VALUE 
       
       The net asset value of the shares of each Portfolio is determined by 
   FAM once daily as of 4:15 P.M., New York City time, on each day that the 
   New York Stock Exchange is open for trading immediately after the 
   declaration of dividends. The New York Stock Exchange is not open for 
   trading on the following holidays: New Year's Day, President's Day, Good 
   Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and 
   Christmas Day. The net asset value per share is computed by dividing the 
   sum of the value of the portfolio securities held by each Portfolio plus 
   any cash or other assets (including interest and dividends accrued but not 
   yet received) minus all liabilities (including accrued expenses) by the 
   total number of shares outstanding at such time, rounded to the nearest 
   cent. Expenses, including the investment advisory and any account 
   maintenance and/or distribution fees, are accrued daily. 

       The per share net asset value of the Class B, Class C and Class D 
   shares of a Portfolio generally will be lower than the per share net asset 
   value of the Class A shares of that Portfolio reflecting the daily expense 
   accruals of the account maintenance distribution and higher transfer 
   agency fees applicable with respect to the Class B, Class C and Class D 
   shares and daily expense accruals of the account maintenance fees 
   applicable with respect to the Class D shares. Moreover the per share net 
   asset value of the Class B and Class C shares generally will be lower than 
   the per share net asset value of its Class D shares reflecting the daily 
   expense accruals of the distribution fees and higher transfer agency fees 
   applicable with respect to the Class B and Class C shares. It is expected, 
   however, that the per share net asset value of the four classes of a 
   Portfolio will tend to converge immediately after the payment of 
   dividends, which will differ by approximately the amount of the expense 
   accrual differential among the classes. 
    
       The Municipal Bonds and money market securities in which each 
   Portfolio invests are traded primarily in the over-the-counter markets and 
   are valued at the most recent bid price or yield equivalent as obtained 
   from dealers that make markets in such securities. Positions in futures 
   contracts are valued at closing prices for such contracts established by 
   the exchange on which they are traded on each day during which trading is 
   conducted thereon. Assets for which market quotations are not readily 
   available are valued at fair value on a consistent basis using methods 
   determined in good faith by the Board of Directors, including valuations 
   furnished by a pricing service retained by the Fund, which may utilize a 
   matrix system for valuations. 















                                       12

       It is the intention of FAM, subject to guidelines established by the 
   Board of Directors of the Fund, to hold Insured Municipal Bonds in the 
   Insured Portfolio which are in default, or in significant risk of default, 
   in the payment of principal or interest until the default has been cured 
   or the principal and interest are paid by the issuer or the insurer. In 
   accordance with such guidelines, FAM will consider the following factors 
   in determining the effective value of Insured Municipal Bonds in the 
   Insured Portfolio which are in default or in significant risk of default, 
   in the payment of principal or interest: (1) the market value of the 
   bonds; (2) the market value of securities of similar issuers whose 
   securities carry similar interest rates; and (3) the value of the 
   insurance guaranteeing interest and principal payments. Absent unusual or 
   unforeseen circumstances, the value ascribed to the insurance feature of 
   the bonds would be the difference between the market value of the bonds 
   and the market value of securities of a similar nature which are not in 
   default or significant risk of default. It is the position of the Board of 
   Directors that this is a fair method of valuing the insurance feature and 
   reflects a proper valuation method in accordance with the provisions of 
   the Investment Company Act of 1940. This method of valuing securities will 
   mean that shareholders of the Insured Portfolio, whether they decide to 
   redeem or decide to retain their investment in the Insured Portfolio, will 
   in normal circumstances receive the benefit of the insurance. Because of 
   the unusual circumstances surrounding the bonds held in the Insured 
   Portfolio which were in default at the end of the Fund's last fiscal year, 
   the insurance feature was valued in an amount which, when combined with 
   the market value of the bonds, resulted in the bonds' having an effective 
   value of par. 
    
                             PORTFOLIO TRANSACTIONS 

       Under the Investment Company Act of 1940, persons affiliated with the 
   Fund are prohibited from dealing with the Fund as a principal in the 
   purchase and sale of securities unless an exemptive order allowing such 
   transactions is obtained from the Securities and Exchange Commission. 
   Since over-the-counter transactions are usually principal transactions, 
   affiliated persons of the Fund, including Merrill Lynch, may not serve as 
   a dealer in connection with transactions with the Fund. However, the Fund 
   has obtained an exemptive order permitting it to engage in certain 
   principal transactions involving high quality short-term Municipal Bonds. 
   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 Investment Company Act in order to seek to 
   recapture underwriting and dealer spreads from affiliated entities. The 
   Directors have considered the possibilities of seeking to recapture 
   spreads for the benefit of the Fund and, after considering factors deemed 
   relevant, have made a determination not to seek such recapture at this 
   time. The Board will reconsider this matter from time to time. 

       Under the Investment Company Act of 1940, the Fund may not purchase 
   Municipal Bonds from any underwriting syndicate of which Merrill Lynch is 
   a member except pursuant to an exemptive order or rules adopted by the 
   Securities and Exchange Commission. During the year ended June 30, 1993, 
   the Fund made no purchases of Municipal Bonds in transactions pursuant to 
   an exemptive order or such a rule. During the year ended June 30, 1994, 
   the Fund purchased $230,231,897 of Municipal Bonds in 77 transactions 
   pursuant to an exemptive order or such a rule. 

       The Fund does not expect to use any particular dealer in the execution 
   of transactions for its Portfolios, but, subject to obtaining the best net 
   results, dealers who provide supplemental investment research (such as 
   economic data and market forecasts) to FAM may receive orders for 
   transactions by any Portfolio. Information so received will be in addition 
   to and not in lieu of the services required to be performed by FAM under 
   its Investment Advisory Agreement and FAM's expenses will not necessarily 
   be reduced as a result of the receipt of such supplemental information. 














                                       13
   <PAGE> 72 

       FAM expects that the portfolio turnover rate for the Insured Portfolio 
   and the National Portfolio should not generally exceed 100%. Because of 
   the short-term nature of the Limited Maturity Portfolio, its turnover rate 
   may be substantially higher. In any particular year, however, market 
   conditions could result in portfolio activity of a Portfolio at a greater 
   or lesser rate than anticipated. 

                               PURCHASE OF SHARES 
   
       The Fund has entered into separate distribution agreements (the 
   "Distribution Agreements") with the Distributor in connection with the 
   offering of each class of shares of the three Portfolios. The Distribution 
   Agreements obligate the Distributor to pay certain expenses in connection 
   with the offering of the Fund's shares. 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 
   Investment Advisory Agreement described above. 
    
   ALTERNATIVE SALES ARRANGEMENTS 
   
       The Fund is a series fund comprised of three separate Portfolios. All 
   three Portfolios are divided into four classes of shares under the Merrill 
   Lynch Select Pricing SM System. Class A and Class D shares of the three 
   Portfolios are sold to investors choosing the initial sales charge 
   alternative and Class B and Class C shares are sold to investors choosing 
   the deferred sales charge alternative. Each Class A, Class B, Class C and 
   Class D share of a Portfolio represents an identical interest in the 
   investment portfolio of the Portfolio, has the same rights and is 
   identical in all respects to the other classes of shares, except that 
   Class B, Class C and Class D shares of the Portfolio 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 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 the distribution fee is paid. Each class has 
   different exchange privileges. See "Exchange Privilege." 

   INITIAL SALES CHARGE ALTERNATIVES-CLASS A and Class D SHARES 


    
   
       For the year ending June 30, 1994, sales charges were $3,435,864, of 
   which the Distributor received $343,837 and Merrill Lynch received 
   $3,092,027. For the year ending June 30, 1993, sales charges were 
   $5,700,495, of which the Distributor received $496,721 and Merrill Lynch 
   received $5,203,774. For the year ended June 30, 1992, sales charges for 
   Class A shares of the Insured Portfolio, the National Portfolio and the 
   Limited Maturity Portfolio were $4,922,010, of which the Distributor 
   received $444,198 and Merrill Lynch received $4,477,812. All of such sales 
   charges were attributable to payments of initial sales charges in 
   connection with purchases of Class A shares of the Portfolios. 
    

       Reduced Initial Sales Charges-Class A and Class D Shares. As set forth 
   in the Prospectus, a reduced sales charge is available for any purchase in 
   excess of $25,000 (in the case of the Insured Portfolio and National 
   Portfolio) and $100,000 for the Limited Maturity Portfolio of Class A or 
   Class D shares of a Portfolio. The term "purchase" as used in the 
   Prospectus and Statement of Additional Information in connection with 
   investment in Class A and Class D shares of the Fund refers to a single 
   purchase by an individual, or to concurrent purchases, which in the 
   aggregate are at least equal to the prescribed amounts by an individual, 
   his spouse and their 















                                       14
   <PAGE> 73 

   children under the age of 21 years purchasing shares for his or their own 
   account and to single purchases by a trustee or fiduciary purchasing 
   shares for a single trust or 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 Investment 
   Company Act of 1940, but does not include purchases by any such company 
   which has not been in existence for at least six months or 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 
   will not include purchases by any group of individuals whose sole 
   organizational nexus is that the participants therein are credit card 
   holders of a company, policyholders of an insurance company, customers of 
   either a bank or broker-dealer or clients of an investment adviser. 

       Right of Accumulation. Reduced sales charges are applicable through a 
   right of accumulation under which investors are permitted to purchase 
   shares of any of the three Portfolios 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 the shares of all of the 
   Portfolios 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, and 
   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 benefits 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 
   of Class A and Class D shares of the Portfolios, or any other MLAM-advised 
   mutual funds, where purchases of such shares aggregating $25,000 or more 
   for the Insured Portfolio and National Portfolio or $100,000 or more for 
   the Limited Maturity Portfolio are made through any dealer within a 
   13-month period starting with the first purchase pursuant to a Letter of 
   Intention in the form provided by the Distributor. The Letter of Intention 
   is not a binding obligation to purchase any amount of Class A or Class D 
   shares, but its execution will result in the purchaser's paying a lower 
   sales charge at the appropriate quantity purchase level. The Letter of 
   Intention is available only to investors whose accounts are maintained at 
   the Fund's Transfer Agent. A purchase not originally made pursuant to a 
   Letter of Intention may be included under a subsequent letter 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 Portfolios and of other MLAM-advised mutual funds (or 
   eligible shares) 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 
   the Letter of Intention will be applied only to new purchases. If the 
   total amount of shares purchased does not equal the amount stated in the 
   Letter of Intention (minimum of $25,000 for the National and Insured 
   Portfolio or $100,000 for the Limited Maturity Portfolio), the 
   investor will be notified and must pay, within 20 days of the expiration 
   of such Letter, the difference between the sales charge on 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 
   and Class D shares equal to five percent of the intended amount will be 
   held in escrow during the 13-month period (while remaining registered in 
   the name of the purchaser) for this purpose and will be involuntarily 
   redeemed to pay the additional sales charge, if necessary. The first 
   purchase under the Letter of Intention must be at least five percent of 
   the dollar amount of such Letter. If during the term of such Letter a 
   purchase brings the total amount invested to an amount equal to or in 
   excess of the amount indicated in the Letter, the purchaser will be 
   entitled on that purchase and subsequent purchases to the reduced 
   percentage sales charge 











                                       15
   <PAGE> 74 

   which would be applicable to a single purchase equal to the total dollar 
   value of the shares then being purchased plus the total cost of all shares 
   previously purchased under such Letter, but there will be no retroactive 
   reduction of the sales charges 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 any Portfolio that creates a sales 
   charge will count toward completing a new or existing Letter of Intention 
   in any Portfolio. 

       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. 

       Employer Sponsored Non-Qualified After-Tax Savings and Investment 
   Programs. Class A and Class D shares are offered at net asset value to 
   employer sponsored non-qualified After-Tax Savings and Investment programs 
   maintained on the Merrill Lynch Group Employee Services system, provided 
   the program, or certain other plans or programs sponsored by the employer, 
   has $5 million or more in existing plan assets initially invested in 
   portfolios, mutual funds or trusts advised by the Investment Adviser or an 
   affiliate. Class A and Class D shares are also offered at net asset value 
   to After-Tax Savings and Investment programs, provided the program has 
   accumulated $5 million or more in existing assets invested in mutual funds 
   advised by the Investment Adviser or an affiliated adviser charging a 
   front-end sales charge or contingent deferred sales charge. In this case 
   as well, assets of certain other plans sponsored by the same sponsor or an 
   affiliated sponsor may be aggregated. The Class A and Class D shares share 
   reduced load breakpoints also apply to these aggregated assets. After-Tax 
   Savings and Investment programs are also offered Class A or Class D shares 
   at net asset value, provided such plan initially has 1,000 or more 
   employees eligible to participate in the plan. Employees eligible to 
   participate in such plans of the same sponsoring employer or its 
   affiliates may be aggregated. The minimum initial and subsequent purchase 
   requirements are waived in connection with all the above-referenced plans. 

       Merrill Lynch Blueprint SM Program. Class D shares of any of the three 
   Portfolios are offered to participants in the Merrill Lynch Blueprint SM 
   Program ("Blueprint"). In addition, participants in Blueprint who own 
   Class A shares of a Portfolio may purchase additional Class A shares of 
   the Portfolio through Blueprint. Blueprint is directed to small investors, 
   group IRAs and participants in certain affinity groups such as credit 
   unions and trade associations. Investors placing orders to purchase Class 
   A or Class D shares of a Portfolio through Blueprint will acquire the 
   shares at net asset value plus a sales charge calculated in accordance 
   with Blueprint sales charge schedule (i.e., up to $5,000 at 0.80% for 
   Limited Maturity Portfolio, up to $5,000 at 3.5% for the Insured Portfolio 
   or National Portfolio, and $5,000.01 or more at the standard disclosed 
   sales charge rate in the Prospectus). In addition, Class A or Class D 
   shares of the Portfolios are being offered at net asset value plus a sales 
   charge of 1/2 of 1% for corporate or group IRA programs placing orders to 
   purchase their Class A or Class D shares through Blueprint. However, 
   services, including the exchange privilege, available to Class A or Class 
   D shareholders through Blueprint may differ from those available to other 
   investors. Class A and Class D shares are offered at net asset value, to 
   Blueprint participants through the Merrill Lynch Directed IRA Rollover 
   Program ("IRA Rollover Program") available from Merrill Lynch Business 
   Financial Services, a business unit of Merrill Lynch. The IRA Rollover 
   Program is available to custodian rollover assets from Employee Sponsored 
   Retirement and Savings Plans (as defined below) whose Trustee and/or Plan 
   Sponsor has entered into a Merrill Lynch Directed IRA Rollover Program 
   Service Agreement. Orders for purchases and redemptions of Class A or 
   Class D shares of the Portfolios may be grouped for execution purposes 
   which, in some circumstances, may involve the execution of such orders two 
   business days following the day such orders are placed. The minimum 
   initial purchase price is $100, with a $50 minimum for subsequent 
   purchases through Blueprint. There are no minimum initial or subsequent 
   purchase requirements for participants who are part of an 











                                       16

   automatic investment plan. Additional information concerning purchases 
   through Blueprint, including any annual fees and transaction charges, is 
   available from Merrill Lynch, Pierce, Fenner & Smith Incorporated, The 
   Blueprint SM Program, P.O. Box 30441, New Brunswick, New Jersey 
   08989-0441. 

       Closed-End Fund 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 MLAM or
   the Investment Adviser who purchased such closed-end fund shares prior to
   October 21, 1994 and wish to reinvest the net proceeds from 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 purchase 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 the
   closed-end fund shares must be made through Merrill Lynch, and the net
   proceeds therefrom must be immediately reinvested in Eligible Class A or
   Class D shares. Second, the closed-end fund shares must either have been
   acquired in the initial public offering or be shares representing dividends
   from shares of common stock acquired in such offering. Third, the closed-end
   fund shares must have been continuously maintained in a Merrill Lynch
   securities account. Fourth, there must be a minimum purchase of $250 to be
   eligible for the investment option. Class A shares of the Fund are offered at
   net asset value to shareholders of Merrill Lynch Senior Floating Rate Fund,
   Inc. ("Senior Floating Rate Fund") who wish to reinvest the net proceeds from
   a sale of certain of their shares of common stock of Senior Floating Rate
   Fund in shares of the Fund. In order to exercise this investment option,
   Senior Floating Rate Fund shareholders must sell their Senior Floating Rate
   Fund shares to the Senior Floating Rate Fund in connection with a tender
   offer conducted by the Senior Floating Rate Fund and reinvest the proceeds
   immediately in the Fund. This investment option is available only with
   respect to the proceeds of Senior Floating Rate Fund shares as to which no
   Early Withdrawal Charge (as defined in the Senior Floating Rate Fund
   prospectus) is applicable. Purchase orders from Senior Floating Rate Fund
   shareholders wishing to exercise this investment option will be accepted only
   on the day that the related Senior Floating Rate Fund tender offer terminates
   and will be effected at the net asset value of the Fund at such day.

       Purchase Privileges of Certain Persons. Directors of the Fund, members of
   the Boards of other MLAM-advised investment companies,  ML & Co., Inc. and
   its subsidiaries, (the term "subsidiaries", when used herein with respect to
   Merrill Lynch & Co., Inc., includes MLAM, FAM and certain other entities
   directly or indirectly wholly-owned and controlled by Merrill Lynch & Co.,
   Inc.), 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 will be offered at net asset value, without 
   sales charge, to an investor who has a business relationship with a 
   financial consultant who joined Merrill Lynch from another investment firm 
   within six months prior to the date of purchase by such investor, if the 
   following conditions are satisfied. First, the investor must advise 
   Merrill Lynch that it will purchase Class D shares of the Fund with 
   proceeds from a redemption of a mutual fund that was sponsored by the 
   financial consultant's previous firm and was subject to a sales charge 
   either at the time of purchase or on a deferred basis. Second, the 
   investor also must establish that such redemption had been made within 60 
   days prior to the investment in the Fund, and the proceeds from the 
   redemption had been maintained in the interim in cash or a money market 
   fund. 

       Class D shares of the Fund are also offered at net asset value, 
   without sales charge, to an investor who has a business relationship with 
   a Merrill Lynch financial consultant and who has invested in a mutual fund

   sored 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 such fund was subject to a sales charge either at the time of purchase or
   on a deferred basis. Second, such purchase of Class D shares must be made
   within 90 days after such notice.

       Class D shares of the Fund will be offered at net asset value, without 
   sales charge, to an investor who has a business relationship with a 
   Merrill Lynch financial consultant and who has invested in a mutual fund 
   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 such shares of other mutual fund and that 
   such shares have been outstanding for a period of no less than six months. 
   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. 

       A purchase of $1 million or more in a single transaction by an investor,
   or a purchase by a TMA SM Managed Trust, of Class A and Class D Shares of the
   Fund's Portfolios will not be subject to an initial sales charge. Such
   purchases will be subject to a contingent deferred sales charge if the shares
   are redeemed within one year after purchase at the following rates: 1.00% on
   purchases of $1,000,000 to $2,500,000; 0.60% on purchases of $2,500,000 to
   $3,500,000; 0.40% on purchases of $3,500,000 to $5,000,000; and 0.25% on
   purchases of more than $5,000,000 in lieu of paying an initial sales charge.

       Acquisition of Certain Investment Companies. The public offering price 
   of Class D shares of the Portfolios may be reduced to the net asset value 
   per share in connection with the acquisition of the assets of or merger or 
   consolidation with a personal holding company or a public or private 
   investment company. The value of the assets or company acquired in a 
   tax-free transaction may in appropriate cases be adjusted to reduce 
   possible adverse tax consequences to the Fund which might result from an 
   acquisition of assets having net unrealized appreciation which is 
   disproportionately higher at the time of acquisition than the realized or 
   unrealized appreciation of the Fund. 

       The issuance of Class D shares for consideration other than cash is 
   limited to bona fide reorganizations, statutory mergers or other 
   acquisitions of portfolio securities which (i) meet the investment 
   objectives and policies of the Fund; (ii) are acquired for investment and 
   not for resale (subject to the understanding that the disposition of the 
   Fund's portfolio securities shall at all times remain within its control); 
   and (iii) are liquid securities, the value of which is readily 
   ascertainable, which are not restricted as to transfer either by law or 
   illiquidity 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). 

       Purchases by Banks. Class A shares of the Fund's Insured Portfolio may 
   be purchased at net asset value, without a sales charge, by banks which 
   have invested a minimum of $25 million in such shares.

       Distribution Plans. Reference is made to "Purchase of Shares-
   Distribution Plans" in the Prospectus for certain information with 
   respect to the distribution plans for Class B and Class C shares 
   pursuant to Rule 12b-1 under the Investment Company Act (each, a 
   "Distribution Plan") with respect to the account maintenance and/or 
   distribution fees paid by the Fund to the Distributor with respect to such 
   classes. 
    














                                       18

       Payments of the account maintenance fees and/or distribution fees are 
   subject to the provisions of Rule 12b-1 under the Investment Company Act 
   of 1940. Among other things, each Distribution Plan provides that the 
   Distributor shall provide and the directors shall review quarterly reports 
   of the disbursement of the account maintenance and/or distribution fees 
   paid to the Distributor. In their consideration of each Distribution Plan, 
   the directors must consider all factors they deem relevant, including 
   information as to the benefits of the Distribution Plan to the Fund and 
   the related class of shareholders of the relevant Portfolio. Each 
   Distribution Plan further provides that, so long as the Distribution Plan 
   remains in effect, the selection and nomination of directors who are not 
   "interested persons" of the Fund, as defined in the Investment Company 
   Act of 1940 (the "Independent Directors"), shall be committed to the 
   discretion of the Independent Directors then in office. In approving each 
   Distribution Plan in accordance with Rule 12b-1, the Independent Directors 
   concluded that there is reasonable likelihood that such Distribution Plan 
   will benefit the Fund and the related class of shareholders of the 
   Portfolio. Each Distribution Plan can be terminated at any time, without 
   penalty, by the vote of a majority of the Independent Directors or by the 
   vote of the holders of a majority of the outstanding related voting 
   securities of the relevant Portfolio. A Distribution Plan cannot be 
   amended to increase materially the amount to be spent by any Portfolio 
   without the approval of the related class of shareholders of such 
   Portfolio and all material amendments are required to be approved by the 
   vote of directors, including a majority of the Independent Directors 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 Fund preserve copies of each class of 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. 

   
       For the year ended June 30, 1994, the Fund paid distribution fees of 
   $6,980,635 with respect to the Class B shares of the Insured Portfolio, 
   distribution fees of $3,496,610 with respect to the Class B shares of the 
   National Portfolio and distribution fees of $466,701 with respect to the 
   Class B shares of the Limited Maturity Portfolio. For the year ended June 
   30, 1993, the Fund paid distribution fees of $6,039,420 with respect to 
   the Class B shares of the Insured Portfolio, distribution fees of 
   $2,578,458 with respect to the Class B shares of the National Portfolio 
   and distribution fees of $112,800 with respect to the Class B shares of 
   the Limited Maturity Portfolio. The distribution-related expenses incurred 
   by the Distributor and Merrill Lynch in connection with the Class B shares 
   consist primarily of financial consultant compensation, branch office and 
   regional operation center selling and transaction processing expenses, 
   advertising, sales promotion and marketing expenses and corporate overhead.
   
   Limitations on the Payment of Deferred Sales Charges

       The maximum sales charge rule in the Rules of Fair Practice of the 
   National Association of Securities Dealers, Inc. ("NASD") imposes a 
   limitation on certain asset-based sales charges such as the distribution 
   fee and the CDSC borne by the Class B and Class C shares but not the 
   account maintenance fee. The maximum sales charge rule is applied 
   separately to each class of each Portfolio. As applicable to the Fund, the 
   maximum sales charge rule limits the aggregate of distribution fee 
   payments and CDSCs payable by the Fund with respect to Class B or Class C 
   shares of a Portfolio to (1) 6.25% of eligible gross sales of such shares, 
   computed separately for each class of a Portfolio (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 


    
   

                                       19
   <PAGE> 78 

   the Class B shares of a Portfolio 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 of the relevant Portfolio, and any CDSCs with respect to that class
   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 tables set forth comparative information as of June 30, 
   1994 with respect to the Class B shares of the Fund indicating the maximum 
   allowable payments that can be made under the NASD maximum sales charge 
   rule and the Distributor's voluntary maximum for the period October 21, 
   1988 (commencement of Class B operations) to June 30, 1994 for the 
   National and Insured Portfolios, and for the period November 2, 1992 
   (commencement of Class B operations) to June 30, 1994 for the Limited 
   Maturity Portfolio. Since Class C shares of the Fund had not been publicly 
   issued prior to the date of this Prospectus, information concerning Class 
   C shares is not provided below:

                              REDEMPTION OF SHARES 
   
       The right to redeem shares or to receive payment with respect to any 
   such redemption may be suspended for any period during which trading on 
   the New York Stock Exchange is restricted as determined by the Securities 
   and Exchange Commission or such Exchange is closed (other than customary 
   weekend and holiday closings), for any period during which an emergency 
   exists as defined by the Commission as a result of which disposal of 
   portfolio securities or determination of the net asset value of any 
   Portfolio is not reasonably practicable, and for such other periods as the 
   Securities and Exchange Commission may by order permit for the protection 
   of shareholders of each Portfolio. Reference is made to "Redemption of 
   Shares" in the Prospectus, for certain information as to the redemption 
   and repurchase of Fund shares. 

       The value of shares at the time of redemption may be more or less than 
   the shareholder's cost, depending on the market value of the securities 
   held by each Portfolio at such time. 


   REINSTATEMENT PRIVILEGE 

    
   
       Holders of Class A or Class D shares of any Portfolio who have 
   redeemed their shares have a one-time privilege to reinstate their 
   accounts by purchasing Class A or Class D shares, as the case may be, of 
   the Portfolio in which they had invested at net asset value without a 
   sales charge up to the dollar amount redeemed. The reinstatement privilege 
   may be exercised as follows. A notice to exercise this privilege along 
   with a check for the amount to be reinstated must be received by the 
   Transfer Agent within 30 days after the date the request for redemption 
   was executed 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. 

   DEFERRED SALES CHARGE-CLASS B 

       As discussed in the Prospectus under "Purchase of Shares-Deferred 
   Sales Charge Alternatives-Class B and Class C Shares", while Class B shares 
   of the Insured Portfolio and National Portfolio redeemed within four years of
   purchase and Class B shares of the Limited Maturity Portfolio redeemed 
   within one year of purchase are subject to a contingent deferred sales 
   charge 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 a Class B shareholder (including one who owns the Class B 
   shares of any Portfolio 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 year ended June 30, 1994, contingent deferred sales charges 
   paid by shareholders of the Fund to the Distributor were $718,890 for the 
   National Portfolio, $1,469,123 for the Insured Portfolio, and $190,903 for 
   the Limited Maturity Portfolio. All of such contingent deferred sales 
   charges were attributable to payments made in connection with redemptions 
   of Class B shares of the Portfolios. 

       Merrill Lynch Blueprint SM Program. Class B shares of all three 
   Portfolios are offered to certain participants in the Merrill Lynch 
   Blueprint SM Program ("Blueprint"). Blueprint is directed to small 
   investors and participants in certain affinity groups such as trade 
   associations and credit unions. Class B shares are offered through

                       DIVIDENDS, DISTRIBUTIONS AND TAXES 
   
       Reference is made to "Dividends, Distributions and Taxes-Federal 
   Income Taxes" in the Prospectus. 

       Each Portfolio intends to qualify to pay "exempt-interest" dividends 
   as defined in Section 852(b)(5) of the Internal Revenue Code of 1986, as 
   amended (the "Code"). Under that section if, at the close of each 
   quarter of its taxable year, at least 50% of the value of its total assets 
   consists of obligations exempt from federal income tax ("tax-exempt 
   obligations"), pursuant to Section 103(a) of the Code (relating to 
   obligations of a state, territory, or a possession of the United States, 
   or any political sub-division of any of the foregoing, or of the District 
   of Columbia), the Portfolio will be qualified to pay exempt-interest 
   dividends to its shareholders. Exempt-interest dividends are dividends or 
   any part thereof (other than any capital gain distributions) paid by the 
   Portfolio which are attributable to interest on tax-exempt obligations and 
   designated by the Portfolio as exempt-interest dividends in a written 
   notice mailed to the Portfolio's shareholders within sixty days after the 
   close of its taxable year. The percentage of the total dividends paid by 
   the Portfolio during any taxable year which qualifies as exempt-interest 
   dividends will be the same for all shareholders of each Portfolio 
   receiving dividends during such year. Exempt-interest dividends may be 
   treated by shareholders for all purposes as items of interest excludible 
   from their gross income under Section 103(a) of the Code. However, a 
   shareholder is advised to consult his tax adviser with respect to whether 
   exempt-interest dividends retain the exclusion under Section 103(a) if 
   such shareholder would be treated as a "substantial user" under Section 
   147(a)(1) with respect to some or all of the tax-exempt obligations held 
   by the Portfolio. 

       Dividends paid by each Portfolio from its taxable income (i.e., 
   interest on money market securities) and distributions of net realized 
   short-term capital gains (whether from tax-exempt or taxable obligations) 
   are taxable to shareholders as ordinary income. If a Portfolio acquires 
   tax-exempt obligations having market discount (generally, obligations 
   acquired for a price less than their principal amount) after April 30, 
   1993, gain on the disposition or retirement of such obligations will be 
   treated as ordinary income to the extent of accrued market discount. To 
   the extent the Portfolio has both taxable and tax-exempt income, expenses 
   of the Fund will be allocated between the taxable and the tax-exempt 
   income on a proportional basis. Since the Portfolio will not invest in the 
   stock of domestic corporations, the dividends received deductions for 
   corporations will not be available. The per share dividends on Class B and 
   Class C shares of any Portfolio will be lower than the per share dividends 
   on Class A and Class D shares of those Portfolios as a result of the 
   account maintenance distribution and higher transfer agency fees 
   applicable to Class B and Class C shares; similarly the per share 
   dividends and distributions on Class D shares will be lower than the per 
   share dividends and distributions on Class A shares as a result of the 
   account maintenance fees applicable with respect to the Class D shares. 
   See "Net Asset Value." The Code provides that interest on indebtedness 
   incurred or continued to purchase or carry shares of the Portfolio is not 
   deductible to the extent attributable to exempt-interest dividends.

       As a result of trading in futures contracts, a Portfolio may realize 
   net capital gains which, when distributed to shareholders, would be 
   taxable in the hands of the shareholders. For example, if the Portfolios 
   sold municipal bond index futures contracts in anticipation of a decline 
   in the value of securities they own and that index in fact declines in 
   value, the Portfolios would realize a capital gain upon the closing out of 
   that futures contract. Furthermore, if a Portfolio holds such a futures 
   contract on the last day of its taxable year, it would be deemed under the 
   Code to have sold that futures contract at its fair market value on the 
   last day of its taxable year and thus would realize a gain or loss. Such 
   gain or loss is treated as 60% long-term capital gain or loss and 40% 
   short-term capital gain or loss (hereinafter "blended gain or loss"), 
   notwithstanding the holding period of the futures contract. Since the 
   futures transaction was entered into to hedge the anticipated decline in 
   the portfolio securities of the Portfolio in question, it is likely that 
   the gain on the futures transactions would be partly or 

  completely offset by a corresponding decline in the value of the portfolio 
   securities of such Portfolio. However, unless the Portfolios sell such 
   securities so as to "realize" such losses in a manner to offset the 
   blended gain for Federal income tax purposes, the Portfolio would have a 
   blended gain. Such blended gain would result in taxable income to the 
   shareholders of the Fund. 

       A redemption resulting in a gain is a taxable event whether or not the 
   reinstatement privilege is exercised. A redemption resulting in a loss 
   will not be a taxable event to the extent the reinstatement privilege is 
   exercised and an adjustment will be made to the shareholder's tax basis in 
   shares acquired pursuant to the reinstatement. For shares of a Portfolio 
   acquired after October 3, 1989, if a shareholder disposes of those shares 
   and subsequently reacquires shares of the Portfolio pursuant to the 
   reinstatement privilege, then the shareholder's tax basis in those shares 
   will be reduced to the extent the sales charge paid to the Portfolio 
   reduces any sales charge such shareholder would have been required to pay 
   on the subsequent acquisition in the absence of the reinstatement 
   privilege. Instead, such sales charge will be treated as an additional 
   amount paid for the subsequently acquired shares and will be included in 
   the shareholder's tax basis for such shares. 

       No gain or loss will be recognized by Class B shareholders on the 
   conversion of their Class B shares for 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 of 
   the converted Class B shares.

       If a shareholder exercises his exchange privilege within 90 days after 
   the date such shares were acquired to acquire shares in such fund or 
   another fund ("New Fund"), then the loss, if any, recognized on the 
   exchange will be reduced (or the gain, if any, increased) to the extent 
   the load charge paid to the Fund reduces any load charge such shareholder 
   would have been required to pay on the acquisition of the New Fund shares 
   in the absence of the exchange privilege. Instead, such load charge will 
   be treated as an amount paid for the New Fund shares and will be included 
   in the shareholder's basis for such 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.
   
       An exchange between funds pursuant to the Exchange Privilege is 
   treated as a sale for federal income tax purposes and, depending upon the 
   circumstances, a short- or long-term capital gain or loss may be realized. 
   In addition, any shareholder of the Fund who exercises the Exchange 
   Privilege and becomes a shareholder of another fund must certify to such 
   other fund his Social Security Number or Taxpayer Identification Number 
   and 







                                       24
   <PAGE> 83 

   that he is not subject to the backup withholding tax if he wishes to avoid a
   31% backup withholding tax on the gross proceeds paid by such other fund on
   redemption of shares and on dividend distributions made to him by such other
   fund.

       Any dividend declared by a Portfolio in October, November or December 
   of any year and made payable to shareholders of record in such a month 
   will be deemed to be received on December 31 of such year if actually paid 
   during the following January. Accordingly, those dividends, to the extent 
   taxable, will be taxable to shareholders in the year declared, and not in 
   the year in which shareholders actually receive the dividend. 
       
       Not later than sixty days after the end of each fiscal year of the 
   Fund, the Fund will send to its shareholders the written notice required 
   by the Code designating the amount of its dividends that constitute 
   exempt-interest dividends, the amount of the dividends and distributions 
   which are ordinary taxable income and the amount of distributions which 
   are taxable to shareholders as long-term capital gains. 

     Every person required to file a tax return must disclose on that 
   return the amount of exempt-interest dividends received from a Portfolio 
   during the taxable year. The disclosure of this amount is for information 
   purposes only. In addition, with respect to a shareholder who receives 
   exempt-interest dividends on shares held for less than six months, any 
   loss on the sale or exchange of such shares will, to the extent of the 
   amount of such exempt-interest dividends, be disallowed. 

       Interest income with respect to certain tax-exempt bonds, known as 
   "private activity" bonds, is a preference item for purposes of the 
   corporate and individual alternative minimum tax. To the extent that a 
   Portfolio invests in private activity bonds, shareholders of the Portfolio 
   will have preference items attributable to their proportionate shares of 
   the interest income received by the Portfolio from such bonds, thereby 
   increasing a Shareholders' alternative minimum taxable income. In 
   addition, a corporation must increase its alternative minimum taxable 
   income by 75 percent of the amount by which adjusted current earnings 
   exceed alternative minimum taxable income (without regard to this 
   provision or the alternative net operating loss deduction). Adjusted 
   current earnings are computed by making certain adjustments, which 
   generally follow the rules applicable to corporations in computing 
   earnings and profits. All tax-exempt dividends received by the corporate 
   shareholders of a Portfolio are included in their current earnings, thus, 
   increasing a corporate shareholders' alternative minimum taxable income. 

       The Code imposes a four percent nondeductible excise tax on a 
   regulated investment company, such as a Portfolio of the Fund, if the 
   company does not distribute to its shareholders during the calendar year 
   an amount equal to 98 percent of the investment company's taxable income, 
   with certain adjustments, for such calendar year, plus 98 percent of the 
   company's capital gain net income for the one-year period ending on 
   October 31 of such calendar year. In addition, an amount equal to any 
   undistributed investment company taxable income or capital gain net income 
   from the previous calendar year must also be distributed to avoid the 
   excise tax. The excise tax is imposed on the amount by which a company 
   does not meet the foregoing distribution requirements. The excise tax will 
   not, however, generally apply to the tax-exempt income of a regulated 
   investment company, such as a Portfolio of the Fund, that pays 
   exempt-interest dividends. In addition, if a Portfolio has taxable income 
   that would be subject to the excise tax, the Fund intends to distribute 
   the income of such Portfolio so as to avoid payment of the excise tax. 
   
       At June 30, 1994, the Fund had a net capital loss carryforward of 
   approximately $4,250,000 in the Limited Maturity Portfolio, of which 
   $1,416,000 expires in 1997, $2,787,000 expires in 1998, $22,000 expires in 
   1999 and $25,000 expires in 2002. These will be available to offset like 
   amounts of any future taxable gains.

       The foregoing is a general and abbreviated summary of the applicable 
   provisions of the Code and Treasury Regulations presently in effect. For 
   the complete provisions, reference should be made to the pertinent Code 
   sections and the Treasury Regulations promulgated thereunder. The Code and 
   these Regulations are subject to change by legislative or administrative 
   action. 

                          SYSTEMATIC WITHDRAWAL PLANS 

       A holder of Class A or Class D shares of any of the three Portfolios 
   may elect to make systematic withdrawals of either a monthly or calendar 
   quarterly basis as provided below. Quarterly withdrawals of such shares 
   are available for shareholders who have acquired Class A or Class D shares 
   having a value, based upon cost or the current offering price, of $5,000 
   or more, and monthly withdrawals are available for shareholders with Class 
   A or Class D shares with such a value of $10,000 or more.
    
   
       At the time of each withdrawal payment, sufficient Class A or Class D 
   shares are redeemed from those on deposit in the shareholder's account to 
   provide the withdrawal payment specified by the shareholder. The 
   shareholder may specify either a dollar amount or a percentage of the 
   value of his Class A or Class D shares. Redemptions will be made at net 
   asset value as determined at the close of business on the New York Stock 
   Exchange (currently 4:00 pm New York time) on the 24th day of each month 
   or the 24th day of the last month of each quarter, whichever is 
   applicable. If the Exchange is not open for business on that day, 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 automatically reinvested in 
   Class A or Class D shares, respectively. A shareholder's Systematic 
   Withdrawal Plan Account is automatically reinvested in shares of the same 
   class. A shareholder's Systematic Withdrawal Plan may be terminated at any 
   time, without charge or penalty, by the shareholder, the Fund, the Fund's 
   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 correspondingly reduced. 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 additions to an Investment 
   Account in which an election has been made to receive systematic 
   withdrawals unless such addition 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. 

       A Class A or Class D shareholder whose shares are held within a CMA|Pr 
   or CBA|Pr Account may elect to have shares redeemed on a monthly, bimonthly, 
   quarterly, semiannual or annual basis through the Systematic Redemption 
   Program. The minimum fixed dollar amount redeemable is $25. The proceeds 
   of systematic redemptions will be posted to the shareholder's account five 
   business days after the date the shares are redeemed. Monthly systematic 
   redemptions will be made at net asset value on the first Monday of each 
   month, bimonthly systematic redemptions will be made at net asset value on 
   the first Monday of every other month, and quarterly, semiannual or annual 
   redemptions are made at net asset value on the first Monday of months 
   selected at the shareholder's option. If the first Monday of the month is 
   a holiday, the redemption will be processed at net asset value on the next 
   business day. The Systematic Redemption Program is not available if Fund 
   shares are being purchased within the account pursuant to the Automatic 
   Investment Program. For more information on the Systematic Redemption 
   Program, eligible shareholders should contact their Financial Consultant.

                               EXCHANGE PRIVILEGE
   
       Shareholders of each class of shares of a Portfolio of the Fund have 
   an exchange privilege with other Portfolios of the Fund and with certain 
   other MLAM-advised mutual funds listed below. Under the Merrill Lynch 
   Select PricingSM System, Class A shareholders may exchange Class A shares of 
   a Portfolio for Class A shares of another Portfolio or a second 
   MLAM-advised mutual fund if the shareholder holds any Class A shares of 
   the other Portfolio or second fund in his account in which the exchange is 
   made at the time of the exchange or is otherwise eligible to purchase 
   Class A shares of the second fund. If the Class A shareholder wants to 
   exchange Class A shares for shares of another Portfolio or a second 
   MLAM-advised mutual fund, and the shareholder does not hold Class A shares 
   of the other Portfolio or second fund in his account at the time of the
exchange and is not otherwise eligible to acquire Class A shares of the 
   other Portfolio or second fund, the shareholder will receive Class D 
   shares of the other Portfolio or second fund as a result of the exchange. 
   Class D shares also may be exchanged for Class A shares of another 
   Portfolio or 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 
   other Portfolio or second fund in the account in which the exchange is 
   made or is otherwise eligible to purchase Class A shares of the other 
   Portfolio or second fund. Class B, Class C and Class D of a Portfolio 
   shares will be exchangeable with shares of the same class of another 
   Portfolio or 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 
   Portfolio is "tacked" to the holding period of the newly acquired shares 
   of the other Portfolio or other Fund as more fully described below. Class 
   A, Class B, Class C and Class D shares also will be exchangeable for 
   shares of certain MLAM-advised money market funds specifically designated 
   below as available for exchange by holders of Class A, Class B, Class C or 
   Class D shares. Shares with a net asset value of at least $100 are 
   required to qualify for the exchange privilege, except that there is no 
   minimum value of shares which must be exchanged by shareholders of the 
   Insured Portfolio who exchange their shares for shares of either the 
   National Portfolio or the Limited Maturity Portfolio and any shares 
   utilized in an exchange must have been held by the shareholder for at 
   least 15 days. The exchange privilege available to participants in the 
   Merrill Lynch BlueprintSM Program may be different from that available to 
   other investors. 

       Exchanges of Class A and Class D shares of a Portfolio outstanding 
   ("outstanding Class A and Class D shares") for Class A or Class D shares 
   of another Portfolio or 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' will 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, dividend reinvestment Class A or Class 
   D shares will be exchanged into the Class A or Class D shares of the other 
   funds or into shares of the Class A or Class D money market funds without 
   a sales charge. 

       In addition, the Fund offers to exchange Class B and Class C shares of 
   a Portfolio outstanding ("outstanding Class B or Class C shares") for 
   Class B or Class C shares respectively of another Portfolio or any of the 
   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 redemp-














                                       27

   tion of the outstanding shares. Class B shareholders of a Portfolio
   exercising the exchange privilege will continue to be subject to that
   Portfolio's contingent deferred sales charge schedule if such schedule is
   higher than the CDSC schedule relating to the new Class B shares acquired
   through the use of the exchange privilege. In addition, Class B shares of the
   Portfolio acquired through the use of the exchange privilege will be subject
   to that Portfolio's CDSC schedule if such schedule is higher than the CDSC
   schedule relating to the Class B shares of the fund or Portfolio from which
   the exchange has been made. For purposes of computing the sales charge that
   may be payable on a disposition of the new Class B or Class C 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 or Class C shares of the National Portfolio for those of the
   Merrill Lynch Basic Value Fund, Inc. after having held the National Portfolio
   Class B shares for two and a half years. The 2% contingent deferred sales
   charge that generally would apply to a redemption would not apply to the
   exchange. Two years later the investor may decide to redeem the Class B
   shares of Merrill Lynch Basic Value Fund, Inc. and receive cash. There will
   be no contingent deferred sales charge due on this redemption, since by
   "tacking" the two and a half year holding period of National Portfolio Class
   B shares to the two year holding period for the Merrill Lynch Basic Value
   Fund, Inc. Class B shares, the investor will be deemed to have held the new
   Class B shares for more than four years.

       Shareholders also may exchange shares of the Fund into shares of a 
   money market fund advised by the Investment Adviser or its affiliates, but 
   the period of time that Class B or Class C shares are held in a Class B or 
   Class C money market fund will not count towards satisfaction of the 
   holding period requirement for purposes of reducing the CDSC or, with 
   respect to the Class B shares, towards satisfaction of the conversion 
   period. However, shares of a Class B money market fund which were acquired 
   as a result of an exchange for Class B or Class C shares of a fund may, in 
   turn, be exchanged back into Class B or Class C shares of any fund 
   offering such shares, in which event the holding period for Class B or 
   Class C shares of the fund will be aggregated with previous holding 
   periods for purposes of reducing the CDSC. Thus, for example, an investor 
   may exchange Class B shares of the National Portfolio for shares of 
   Merrill Lynch Institutional Fund ("Institutional Fund") after having 
   held the Class B shares for two and a half years, and two 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 National Portfolio 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 one 
   and a half years, any subsequent redemption will not incur a CDSC.

   respective investment objectives is as follows:

                                10% of its total assets in repurchase 
                                agreements secured by such obligations.


       Before effecting an exchange, shareholders of the Fund should obtain a 
   currently effective prospectus of the fund into which the exchange is to 
   be made. Exercise of the exchange privilege is treated as a sale for 
   Federal income tax purposes and, depending on the circumstances, a short- 
   or long-term capital gain or loss may be realized. In addition, a 
   shareholder exchanging shares of any of the funds may be subject to a 
   backup withholding tax unless such shareholder certifies under penalty of 
   perjury that the taxpayer identification number on file with any such fund 
   is correct and that such shareholder is not otherwise subject to backup 
   withholding. See "Dividends, Distributions and Taxes" below. 

       To exercise the Exchange Privilege, shareholders should contact their 
   listed dealer, who will advise the Fund of the exchange, or the 
   shareholder may write to the Transfer Agent requesting that the exchange 
   be effected. Such letter must be signed exactly as the account is 
   registered with signature(s) guaranteed by "eligible guarantor 
   institution" (including, for example, Merrill Lynch branch offices and 
   certain other financial institutions) as such is defined in Rule 17Ad-15 
   under the Securities Exchange Act of 1934, as amended, the existence and 
   validity of which may be verified by the transfer agent through the use of 
   industry publications. 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. These funds may suspend the continuous 
   offering of their shares to the public at any time and may thereafter 
   resume such offering from time to time. 
   
       The Exchange Privilege may be modified or terminated at any time on 60 
   days' notice. The Fund reserves the right to limit the number of times an 
   investor may exercise the Exchange Privilege. The exchange privilege is 
   available only to U.S. shareholders in states where the exchange legally 
   may be made. 
    
                                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. Total return yield, and tax equivalent yield figures are based
   on the Fund's historical performance and are


                                       38
   <PAGE> 97 

    
   

   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
   Securities and Exchange 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 (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 
   calculation 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.
   
       Set forth below is total return information for the Class A and Class 
   B shares of the Insured Portfolio and National Portfolio and shares of the 
   Limited Maturity Portfolio for the periods indicated. Since Class C and 
   Class D Shares have not been issued prior to the date of this Statement of 
   Additional Information, performance information concerning Class C and 
   Class D shares is not yet provided.

       In order to reflect the reduced sales charges applicable to certain 
   investors the performance data in advertisements distributed to investors 
   whose purchases are subject to reduced sales load, in the case of Class A 
   or Class D shares, or waiver of the contingent deferred sales charge in 
   the case of the Class B and Class C shares, may take into account the 
   reduced, and not the maximum, sales charge or may not take into account 
   the contingent deferred sales charge and therefore may reflect greater 
   total return since, due to the reduced sales charge, a lower amount of 
   expenses is deducted. 
    
       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 
   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 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 ending June 30, 1994 for National 
   Portfolio Class A shares was 5.59%, for National Portfolio Class B shares 
   was 5.05%, for Insured Portfolio Class A shares was 5.20%, for Insured 
   Portfolio Class B shares was 4.65%, for Limited Maturity Portfolio Class A 
   shares was 3.89%, and for Limited Maturity Portfolio Class B shares was 
   3.56%. The tax-equivalent yield for the same period (based on a tax rate 
   of 28%) for National Portfolio Class A shares was 7.76%, for National 
   Portfolio Class B shares was 7.01%, for Insured Portfolio Class A shares 
   was 7.22%, for Insured Portfolio Class B shares was 6.46%, for Limited 
   Maturity Portfolio Class A shares was 5.40%, and for Limited Maturity 
   Portfolio Class B shares was 4.94%. 
    
       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. 

                             ADDITIONAL INFORMATION 

   Description of Municipal Bonds 

       Municipal Bonds include debt obligations issued to obtain funds for 
   various public purposes, including construction of a wide range of public 
   facilities, refunding of outstanding obligations and obtaining funds for 
   general operating expenses and loans to other public institutions and 
   facilities. In addition, certain types of industrial development bonds are 
   issued by or on behalf of public authorities to finance various privately- 
   operated facilities, including pollution control facilities. Such 
   obligations are included within the term Municipal Bonds if the interest 
   paid thereon is exempt from federal income tax. Municipal Bonds also 
   include short-term tax-exempt municipal obligations such as tax 
   anticipation notes, bond anticipation notes, revenue anticipation notes, 
   variable rate demand notes and Public Housing Authority notes that are 
   fully secured by a pledge of the full faith and credit of the United 
   States. 

       The two principal classifications of Municipal Bonds are "general 
   obligation" and "revenue" or "special obligation" bonds. General 
   obligation bonds are secured by the issuer's pledge of faith, credit, and 
   taxing power for the payment of principal and interest. Revenue or special 
   obligation bonds are payable only from the







                                       41
   <PAGE> 100 







   
   revenues derived from a particular facility or class of facilities or, in 
   some cases, from the proceeds of a special excise tax or other specific 
   revenue source such as from the user of the facility being financed. 
   Industrial development bonds are in most cases revenue bonds and do not 
   generally constitute the pledge of the credit or taxing power of the 
   issuer of such bonds. The payment of the principal and interest on such 
   industrial revenue bonds depends solely on the ability of the user of the 
   facilities 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. The Portfolio may also include "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. 
    
       Municipal Bonds may at times be purchased or sold on a delayed 
   delivery basis or a when-issued basis. These transactions arise when 
   securities are purchased or sold by a Portfolio 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 only make commitments to 
   purchase such securities with the intention of actually acquiring the 
   securities, but the Fund may sell these securities prior to the settlement 
   date if it is deemed advisable. Purchasing Municipal Bonds on a 
   when-issued basis involves the risk that the yields available in the 
   market when the delivery takes place may actually be higher than those 
   obtained in the transaction itself; if yields so increase, the value of 
   the when-issued obligation will generally decrease. When a Portfolio 
   engages in when-issued and delayed delivery transactions, the Portfolio 
   relies on the buyer or seller, as the case may be, to consummate the 
   trade. Failure of the buyer or seller to do so may result in the 
   Portfolio's missing the opportunity of obtaining a price considered to be 
   advantageous. The Fund will maintain a separate account as its custodian 
   bank consisting of cash or liquid Municipal Bonds (valued on a daily 
   basis) equal at all times to the amount of the when-issued commitment. 

       Variable rate demand notes ("VRDNs") are tax-exempt obligations 
   which contain a floating or variable interest rate adjustment formula and 
   an unconditional right of demand to receive payment of the unpaid 
   principal balance plus accrued interest upon a short notice period not to 
   exceed seven days. The interest rates are adjustable at intervals ranging 
   from daily up to six months to some prevailing market rate for similar 
   investments, such adjustment formula being calculated to maintain the 
   market value of the VRDN at approximately the par value of the VRDN upon 
   the adjustment date. The adjustments are typically based upon the prime 
   rate of a bank or some other appropriate interest rate adjustment index. 

       The Fund may also invest in VRDNs in the form of participation 
   interests ("Participating VRDNs") in variable rate tax-exempt 
   obligations held by a financial institution, typically a commercial bank 
   ("institution"). Participating VRDNs 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 VRDNs from the institution upon a specified number of 
   days' notice, not to exceed seven days. In addition, the Participating 
   VRDN is backed by an irrevocable letter of credit or guaranty of the 
   institution. The Fund has an undivided interest in the underlying 
   obligation and thus participates on the same basis as the institution in 
   such obligation except that the 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 to the effect that the 
   interest received on Participating VRDNs will be treated as interest from 
   tax-exempt obligations as long as the Fund does not invest more than a 
   limited amount (not more than 20%) of its total assets in such investments 
   and certain other conditions are met. It is contemplated that the Fund 
   will not invest more than a limited amount of its total assets in 
   Participating VRDNs.

       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 maturity of the 
   obligation, and the rating of the issue. The ability of a Portfolio to 
   achieve its investment objective is also dependent on the continuing 
   ability of the issuers of the Municipal Bonds in which the Portfolio 
   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, within a particular classification and between 
   classifications, depending on numerous factors. Furthermore, the rights of 
   holders of Municipal Bonds and the obligations of the issuers of such 
   Municipal Bonds may be subject to applicable bankruptcy, insolvency and 
   similar laws and court decisions affecting the rights of creditors 
   generally and such laws, if any, that may be enacted by Congress or state 
   legislatures imposing a moratorium on the payment of principal and 
   interest or imposing other constraints or conditions on the payment of 
   principal of and interest on Municipal Bonds. 

       From time to time, proposals have been introduced before Congress for 
   the purpose of restricting or eliminating the federal income tax exemption 
   for interest on Municipal Bonds. It may be expected that similar proposals 
   may be introduced in the future. If such a proposal were enacted, the 
   ability of the Portfolios to pay "exempt-interest" dividends might be 
   adversely affected and the Fund would re-evaluate its investment objective 
   and policies and consider changes in its structure. See "Dividends, 
   Distributions and Taxes." 

   Description of Temporary Investments 

       The short-term money market securities in which the Portfolios may 
   invest as temporary investments consist of United States Government 
   securities, United States Government agency securities, domestic bank 
   certificates of deposit and bankers' acceptances, short-term corporate 
   debt securities such as commercial paper, and repurchase agreements. The 
   money market securities must have a stated maturity not in excess of one 
   year from the date of purchase. U.S. Government securities consist of 
   various types of marketable securities issued by or guaranteed as to 
   principal and interest by the U.S. Government and supported by the full 
   faith and credit of the U.S. Treasury. U.S. Government agency securities 
   consist of debt securities issued by government sponsored enterprises, 
   federal agencies and international institutions. Such securities are not 
   direct obligations of the Treasury but involve government sponsorship or 
   guarantees by government agencies or enterprises. The Fund has established 
   the following standards with respect to money market securities in which 
   the Portfolios invest. Commercial paper investments at the time of 
   purchase must be rated "A" by Standard & Poor's Corporation or "Prime" 
   by Moody's Investors Service, Inc. or, if not rated, issued by companies 
   having an outstanding debt issue rated at least "A" by Standard & Poor's 
   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 or by Moody's. 
   The Portfolios may not invest in any securities issued by a commercial 
   bank or a savings and loan association unless the bank or association 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. 

   Insurance on Portfolio Securities 
   
       Set forth below is further information with respect to the Mutual Fund 
   Insurance Policies (the "Policies") which the Fund has obtained from 
   AMBAC Indemnity Corporation ("AMBAC"), Municipal Bond Investors 
   Assurance Corporation ("MBIA") and Financial Security Assurance Inc. 
   ("FSA"), with respect to Insured Municipal Bonds held by the Insured 
   Portfolio (see "Investment Policies of the Portfolios-Insured Portfolio"
   




                                       43

   in the Prospectus). During the fiscal year ended June 30, 1994, the 
   premium for the policies aggregated $74,901 or approximately 0.002% of the 
   average net assets of the Insured Portfolio. During the fiscal year ended 
   June 30, 1993, the premium for the Policies aggregated $162,176 or 
   approximately 0.01% of the average net assets of the Insured Portfolio. 
    
       In determining eligibility for insurance, AMBAC, MBIA and FSA have 
   applied their own standards, which correspond generally to the standards 
   they normally use in establishing the insurability of new issues of 
   Municipal Bonds and which are not necessarily the criteria which would be 
   used in regard to the purchase of Municipal Bonds by the Insured 
   Portfolio. The Policies do not insure (i) municipal securities ineligible 
   for insurance, or (ii) municipal securities which are no longer owned by 
   the Insured Portfolio. In addition, the AMBAC policy does not insure 
   municipal obligations which were insured as to the payment of principal 
   and interest at the time of their issuance by AMBAC. 

       The Policies do not guarantee the market value of the Insured 
   Municipal Bonds or the value of the shares of the Insured Portfolio. In 
   addition, if the provider of an original issuance insurance policy is 
   unable to meet its obligations under such policy or if the rating assigned 
   to the claims paying ability of any such insurer deteriorates, neither 
   AMBAC nor MBIA nor FSA has any obligation to insure any issue held by the 
   Insured Portfolio which is adversely affected by either of the above 
   described events. The AMBAC policy provides for an annual policy period, 
   which is renewable by the Fund for successive annual periods for so long 
   as the Fund is in compliance with the terms of the AMBAC policy. In 
   addition to the payment of premiums, the Policies require that the Insured 
   Portfolio notify AMBAC and MBIA as to all Municipal Bonds in the Insured 
   Portfolio and permit AMBAC and MBIA to audit records. The insurance 
   premiums are payable monthly by the Insured Portfolio in accordance with a 
   premium schedule which was furnished by AMBAC, MBIA and FSA at the time 
   the Policies were issued. Premiums are based upon the amounts covered and 
   the composition of the portfolio. AMBAC has reserved the right to change 
   the premium schedule for any renewal policy period as to any municipal 
   securities purchased by the Insured Portfolio during such renewal period. 
   The FSA policy and the MBIA policy both provide that the premium rate for 
   subsequent purchases by the Insured Portfolio of the same obligations will 
   be determined by FSA or MBIA as of the date of such purchases. 

       AMBAC has received a letter ruling from the Internal Revenue Service, 
   which holds in effect that insurance proceeds representing maturing 
   interest on defaulted municipal obligations paid by AMBAC to municipal 
   bond funds substantially similar to the Insured Portfolio, under policy 
   provisions substantially identical to the policy described herein, will be 
   excludable from federal gross income under Section 103(a) of the Internal 
   Revenue Code. 

   
       AMBAC insures the portfolio of the Insured Portfolio and the prompt 
   payment of the interest and principal of new issues of Municipal Bonds and 
   Municipal Bond portfolios of individuals, banks, trust companies, 
   corporations, insurance companies and units trusts. As of June 30, 1994, 
   the admitted assets of AMBAC were approximately $2.060 billion (unaudited) 
   with a qualified capital of approximately $766.7 million (unaudited). 
   Qualified capital consists of the statutory contingency reserve and 
   policyholders' surplus of the insurance company. 

       FSA insures the prompt payment of interest and principal of new issues 
   of Municipal Bonds and Municipal Bond portfolios of individuals, banks, 
   trust companies, corporations, insurance companies and unit trusts. As of 
   June 30, 1994, the total admitted assets (unaudited) of FSA were 
   approximately $604.8 million with a total capital and surplus (unaudited) 
   of approximately $367.7 million as reported to the Insurance Department of 
   the State of New York.

       MBIA insures the prompt payment of interest and principal of new 
   issues of Municipal Bonds and Municipal Bond portfolios of individuals, 
   banks, trust companies, corporations, insurance companies and unit trusts. 
   As of June 30, 1994, the total admitted assets of MBIA were approximately 
   $3.253 billion (unaudited) with total capital and surplus of approximately 
   $1,049 million (unaudited). 
    

       AMBAC has entered into reinsurance agreements with a number of 
   unaffiliated reinsurers, relating to the municipal bond insurance programs 
   of AMBAC including the insurance obtained by the Fund for the portfolio of 
   the Insured Portfolio. 

       The contracts of insurance relating to the Insured Portfolio and the 
   negotiations in respect thereof represent the only significant 
   relationship between AMBAC, MBIA and FSA and the Fund. Otherwise neither 
   AMBAC or any associate thereof, nor MBIA or any associate thereof, nor FSA 
   or any associate thereof has any material business relationship, direct or 
   indirect, with the Fund. 

       AMBAC, MBIA and FSA are subject to regulation by the department of 
   insurance in each state in which they are qualified to do business. Such 
   regulation, however, is not a guarantee that any of AMBAC, MBIA or FSA 
   will be able to perform on its contractual insurance in the event a claim 
   should be made thereunder at some time in the future. 

       The information relating to AMBAC, MBIA and FSA set forth above, 
   including the financial information, has been furnished by such 
   corporations. Financial information with respect to AMBAC, MBIA and FSA 
   appears in reports filed by AMBAC, MBIA and FSA with state insurance 
   regulatory authorities and is subject to audit and review by such 
   authorities. No representation is made herein as to the accuracy or 
   adequacy of such information with respect to AMBAC, MBIA or FSA or as to 
   the absence of material adverse changes in such information subsequent to 
   the date thereof. 

   Description of Financial Futures Contracts

       Futures Contracts. 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 called for in the contract or, in some 
   instances, to make a cash settlement based upon the value of an instrument 
   or an index of values, at a specified future time for a specified price. 
   Although the terms of a contract call for actual delivery of the 
   underlying financial instrument, or for a cash settlement, in most cases 
   the contracts are closed out before the delivery date without the delivery 
   taking place. The Fund intends to close out its futures contracts prior to 
   the delivery date of such contracts. 

       The National and Limited Maturity Portfolios (the "Portfolios") may 
   sell futures contracts in anticipation of a decline in the value of their 
   investments in municipal bonds. The loss associated with any such decline 
   could be reduced without employing futures as a hedge by selling long-term 
   securities 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 brokerage commissions and 
   dealer spreads and will typically reduce the Portfolio's average yields as 
   a result of the shortening of maturities. 

       The purchase or sale of a futures contract differs from the purchase 
   or sale of a security in that the total cash value reflected by the 
   futures contract is not paid. Instead, an amount of cash or securities 
   acceptable to the Fund's futures commission merchant ("FCM") and the 
   relevant contract market, which varies but is generally about 5% or less 
   of the contract amount, must be deposited with the FCM. This amount is 
   known as "initial margin," and represents a "good faith" deposit 
   assuring the performance of both the purchaser and the seller










                                       45
   <PAGE> 104 






   under the futures contract. Subsequent payments to and from the FCM, known 
   as "maintenance" or "variation margin," are required to be made on a 
   daily basis as the price of the futures contract fluctuates, making the 
   long or short position in the futures contract more or less valuable, a 
   process known as "marking to the market." Prior to the settlement date 
   of the futures contract, the position may be closed out by taking an 
   opposite position which will operate to terminate the position in the 
   futures contract. A final determination of variation margin is then made, 
   additional cash is required to be paid to or released by the FCM, and the 
   purchaser realizes a loss or gain. In addition, a commission is paid on 
   each completed purchase and sale transaction. 

       The sale of financial futures contracts provides an alternative means 
   of hedging a Portfolio against declines in the value of its investments in 
   Municipal Bonds. As such values decline, the value of the Portfolio's 
   positions in the futures contracts are expected to increase, thus 
   offsetting all or a portion of the depreciation in the market value of the 
   Portfolios' fixed income investments which are being hedged. While the 
   Portfolios will incur commission expenses in establishing and closing out 
   futures positions, commissions on futures transactions may be 
   significantly lower than transaction costs incurred in the purchase and 
   sale of fixed income securities. In addition, the ability of the 
   Portfolios to trade in the standardized contracts available in the futures 
   market may offer a more effective hedging strategy than a program to 
   reduce the average maturity of portfolio securities, due to the unique and 
   varied credit and technical characteristics of the municipal debt 
   instruments available to the Portfolios. Employing futures as a hedge may 
   also permit the Portfolios to assume a hedging posture without reducing 
   the yield on their investments beyond any amounts required to engage in 
   futures trading. 

       The Portfolios engage in the purchase and sale of future contracts on 
   an index of municipal securities. These instruments provide for the 
   purchase or sale of a hypothetical portfolio of municipal bonds at a fixed 
   price in a stated delivery month. Unlike most other futures contracts, 
   however, a municipal bond index futures contract does not require actual 
   delivery of securities but results in a cash settlement based upon the 
   difference in value of the index between the time the contract was entered 
   into and the time it is liquidated. 

       The municipal bond index underlying the futures contracts traded by 
   the Portfolios is The Bond Buyer Municipal Bond Index, developed by The 
   Bond Buyer and the Chicago Board of Trade ("CBT"), the contract market 
   on which the futures contracts are traded. As currently structured, the 
   index is comprised of 40 tax-exempt term municipal revenue and general 
   obligation bonds. Each bond included in the index must be rated either A|m- 
   or higher by Standard & Poor's or A or higher by Moody's Investors Service 
   and must have a remaining maturity of 19 years or more. Twice a month new 
   issues satisfying the eligibility requirements are added to, and an equal 
   number of old issues will be deleted from, the index. The value of the 
   index is computed daily according to a formula based upon the price of 
   each bond in the Index, as evaluated by four dealer-to-dealers brokers. 

       The Portfolios may also purchase and sell futures contracts on U.S. 
   Treasury bills, notes and bonds for the same types of hedging purposes. 
   Such futures contracts provide for delivery of the underlying security at 
   a specified future time for a fixed price, and the value of the futures 
   contract generally fluctuates with movements in interest rates. 

       The municipal bond index futures contract, futures contracts on U.S. 
   Treasury securities and options on such futures contracts are traded on 
   the CBT and the Chicago Mercantile Exchange, which, like other contract 
   markets, assures the performance of the parties to each futures contract 
   through a clearing corporation, a nonprofit organization managed by the 
   exchange membership, which is also responsible for handling daily 
   accounting of deposits or withdrawals of margin.







                                       46
   <PAGE> 105 







       The Portfolios may also purchase financial futures contracts when they 
   are not fully invested in municipal bonds in anticipation of an increase 
   in the cost of securities they intend to purchase. As such securities are 
   purchased, an equivalent amount of futures contracts will be closed out. 
   In a substantial majority of these transactions, the Portfolios will 
   purchase municipal bonds upon termination of the futures contracts. Due to 
   changing market conditions and interest rate forecasts, however, a futures 
   position may be terminated without a corresponding purchase of securities. 
   Nevertheless, all purchases of futures contracts by the Portfolios will be 
   subject to certain restrictions, described below. 

       Options on Futures Contracts. An option on a futures contract provides 
   the purchaser with the right, but not the obligation, to enter into a long 
   position in the underlying futures contract (i.e., purchase the futures 
   contract), in the case of a "call" option, or to enter into a short 
   position (i.e., sell the futures contract), in the case of a "put" 
   option, for a fixed price (the "exercise" or "strike" price) up to a 
   stated expiration date. The option is purchased for a non-refundable fee, 
   known as the "premium." Upon exercise of the option, the contract market 
   clearing house assigns each party the appropriate position in the 
   underlying futures contract. In the event of exercise, therefore, the 
   parties are subject to all of the risks of futures trading, such as 
   payment of initial and variation margin. In addition, the seller, or 
   "writer", of the option is subject to margin requirements on the option 
   position. Options on futures contracts are traded on the same contract 
   markets as the underlying futures contracts. 

       The Portfolios may purchase options on futures contracts for the same 
   types of hedging purposes described above in connection with futures 
   contracts. For example, in order to protect against an anticipated decline 
   in the value of securities it holds, a Portfolio could purchase put 
   options on futures contracts, instead of selling the underlying futures 
   contracts. Conversely, in order to protect against the adverse effects of 
   anticipated increases in the cost of securities to be acquired, a 
   Portfolio could purchase call options on futures contracts, instead of 
   purchasing the underlying futures contracts. The Portfolios generally will 
   sell options on futures contracts only to close out an existing position. 

       The Portfolios will not engage in transactions in such instruments 
   unless and until the Investment Adviser determines that market conditions 
   and the circumstances of the Portfolios warrant such trading. To the 
   extent the Portfolios engage in the purchase and sale of futures contracts 
   or options thereon, they will do so only at a level which is reflective of 
   the Investment Adviser's view of the hedging needs of the Portfolios, the 
   liquidity of the market for futures contracts and the anticipated 
   correlation between movements in the value of the futures or option 
   contract and the value of securities held by the Portfolios. 

       Restrictions on the Use of Futures Contracts and Options on Futures 
   Contracts. Under regulations of the Commodity Futures Trading Commission 
   ("CFTC"), the futures trading activities described herein will not 
   result in the Portfolios' being deemed to be "commodity pools," as 
   defined under such regulations, provided that certain trading restrictions 
   are adhered to. In particular, CFTC regulations require that a notice of 
   eligibility be filed and that all futures and option positions entered 
   into by the Portfolios qualify as bona fide hedge transactions, as defined 
   under CFTC regulations, or that any non-qualifying positions be limited so 
   that the sum of the amount of initial margin deposits and premiums paid on 
   such positions would not exceed 5% of the market value of the respective 
   Portfolio's net assets. 

       When either Portfolio purchases a futures contract, it will maintain 
   an amount of cash, cash equivalents or commercial paper or other 
   short-term high grade fixed income securities in a segregated account with 
   the Fund's custodian, so that the amount so segregated plus the amount of 
   initial 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 Transactions in Futures Contracts and Options Thereon. 
   The particular municipal bonds comprising the index underlying the 
   municipal bond index futures contract may vary from the bonds held by the 
   Portfolios. In addition, the securities underlying futures contracts on 
   U.S. Treasury securities will not be the same as securities held by the 
   Portfolios. As a result, the Portfolios' ability effectively to hedge all 
   or a portion of the value of their municipal bonds through the use of 
   futures contracts will depend in part on the degree to which price 
   movements in the index underlying the municipal bond index futures 
   contract, or the U.S. Treasury securities underlying other futures 
   contracts traded, correlate with price movements of the Municipal Bonds 
   held by the Portfolios. 

       For example, where prices of securities in the Portfolios do not move 
   in the same direction or to the same extent as the values of the 
   securities or index underlying a futures contract, the trading of such 
   futures contracts may not effectively hedge the Portfolios' investments 
   and may result in trading losses. The correlation may be affected by 
   disparities in the average maturity, ratings, geographical mix or 
   structure of the Portfolios' investments as compared to those comprising 
   the index, and general economic or political factors. In addition, the 
   correlation between movements in the value of the index underlying a 
   futures contract may be subject to change over time, as additions to and 
   deletions from the index alter its structure. In the case of futures 
   contracts on U.S. Treasury securities and options thereon, the anticipated 
   correlation of price movements between the U.S. Treasury securities 
   underlying the futures or options and Municipal Bonds may be adversely 
   affected by economic, political, legislative or other developments that 
   have a disparate impact on the respective markets for such securities. In 
   the event that the Investment Adviser determines to enter into 
   transactions in financial futures contracts other than the municipal bond 
   index futures contract or futures on U.S. Treasury securities, the risk of 
   imperfect correlation between movements in the prices of such futures 
   contracts and the prices of Municipal Bonds held by the Portfolios may be 
   greater. 

       The trading of futures contracts on an index also entails the risk of 
   imperfect correlation between movements in the price of the futures 
   contract and the value of the underlying index. The anticipated spread 
   between the prices may be affected due to differences in the nature of the 
   markets, such as margin requirements, liquidity and the participation of 
   speculators in the futures markets. The risk of imperfect correlation, 
   however, generally diminishes as the delivery month specified in the 
   futures contract approaches. 

       Prior to exercise or expiration, and absent delivery, a position in 
   futures contracts or options thereon may be terminated only by entering 
   into a closing purchase or sale transaction on the relevant contract 
   market. A Portfolio will enter into a futures or option position only if 
   there appears to be a liquid market therefor, although there can be no 
   assurance that such a liquid market will exist for any particular contract 
   at any specific time. Thus, it may not be economically practicable, or 
   otherwise possible, to close out a position once it has been established. 
   Under such circumstances, a portfolio could be required to make continuing 
   daily cash payments of variation margin in the event of adverse price 
   movements. In such situations, if the Portfolio 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. In 
   addition, the Portfolio may be required to perform under the terms of the 
   futures or option contracts it holds. The inability to close out futures 
   or options positions also could have an adverse impact on the Portfolio's 
   ability effectively to hedge its portfolio. 

       When a Portfolio purchases an option on a futures contract, its risk 
   is limited to the amount of the premium, plus related transaction costs, 
   although this entire amount may be lost. In addition, in order to profit 
   from the purchase of an option on a futures contract, a Portfolio may be 
   required to exercise the option and liquidate the underlying futures 
   contract, subject to the availability of a liquid market. The trading of 
   options on futures






                                       48
   <PAGE> 107 





   contracts 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, although the risk of imperfect correlation generally tends to 
   diminish as the maturity date of the futures contract or expiration date 
   of the option approaches. 

       "Position Limits" are generally imposed on the maximum number of 
   contracts which any person may hold or control at a given time. A contract 
   market may order the liquidation of positions found to be in violation of 
   these limits and it may impose other sanctions or restrictions. The 
   Investment Adviser does not believe that position limits will have any 
   adverse impact on the portfolio strategies for hedging a Portfolio's 
   investments. 

       Further, the trading of futures contracts is subject to the risk of 
   the insolvency of a brokerage firm or the relevant exchange or clearing 
   corporation, which could make it difficult or impossible to liquidate 
   existing positions or to recover margin or other payments due. 

       In addition to the risks of imperfect correlation and lack of a liquid 
   secondary market for such instruments, transactions in futures contracts 
   involve risks related to leveraging such that a change in the price of a 
   futures contract could result in substantial gains or losses. The 
   potential for incorrect forecasts of the direction and extent of interest 
   rate movements within a given time frame also involves the risk of loss in 
   the event such forecasts are inaccurate.

   Computation of Offering Price per Share
     
       The offering price for Class A and Class B shares of the Insured, 
   National and Limited Maturity, based on the value of each Portfolio's net
   asset and the number of shares outstanding asof June 30, 1994, is 
   calculated as set forth below. Information is not provided for Class C or 
   Class D shares since no Class C or Class D shares were publicly offered prior
   to the date of this Statement of Additional Information.

   INDEPENDENT AUDITORS' REPORT
  
   The Board of Directors and Shareholders,
   Merrill Lynch Municipal Bond Fund, Inc.: 

   We have audited the accompanying statements of assets and liabilities, 
   including the schedules of investments, of the Insured, National and 
   Limited Maturity Portfolios of Merrill Lynch Municipal Bond Fund, Inc. as 
   of June 30, 1994, the related statements of operations for the year then 
   ended and changes in net assets for each of the years in the two-year 
   period then ended, and the financial highlights for each of the years in 
   the five-year period then ended. These financial statements and the 
   financial highlights are the responsibility of the Fund's management. Our 
   responsibility is to express an opinion on these financial statements and 
   the financial highlights based on our audits. 
    

   We conducted our audits in accordance with generally accepted auditing 
   standards. Those standards require that we plan and perform the audit to 
   obtain reasonable assurance about whether the financial statements and the 
   financial highlights are free of material misstatement. An audit includes 
   examining, on a test basis, evidence supporting the amounts and 
   disclosures in the financial statements. Our procedures included 
   confirmation of securities owned at June 30, 1994 by correspondence with 
   the custodian and brokers. An audit also includes assessing the accounting 
   principles used and significant estimates made by management, as well as 
   evaluating the overall financial statement presentation. We believe that 
   our audits provide a reasonable basis for our opinion. 

   In our opinion, such financial statements and financial highlights present 
   fairly, in all material respects, the financial position of the Insured, 
   National and Limited Maturity Portfolios of Merrill Lynch Municipal Bond 
   Fund, Inc. as of June 30, 1994, the results of their operations, the 
   changes in their net assets, and the financial highlights for the 
   respective stated periods in conformity with generally accepted accounting 
   principles.

NOTES TO FINANCIAL STATEMENTS

1. Significant Accounting Policies:
Merrill Lynch Municipal Bond Fund, Inc. (the "Fund") is
registered under the Investment Company Act of 1940 as a
diversified, open-end management investment company. The Fund's
Portfolios offer Class A and Class B Shares. Class A Shares are
sold with a front-end sales charge. Class B Shares may be subject
to a contingent deferred sales charge. Both classes of shares
have identical voting, dividend, liquidation and other rights and
the same terms and conditions, except that Class B Shares bear
certain expenses related to the distribution of such shares and
have exclusive voting rights with respect to matters relating to
such distribution expenditures. The following is a summary of
significant accounting policies followed by the Fund.

(a)Valuation of investments--Insured Portfolio: Where bonds in
the Portfolio have not been insured pursuant to policies obtained
by the issuer, the Fund has obtained insurance with respect to
the payment of interest and principal of each bond. Such
insurance is valid as long as the bonds are held by the Fund.

All Portfolios: Municipal bonds and money market securities are
traded primarily in the over-the-counter markets and are valued
at the most recent bid price or yield equivalent as obtained from
dealers that make markets in such securities. Positions in
futures contracts are valued at closing prices as of the close of
such exchanges. Options, which are traded on exchanges, are
valued at their last sale price as of the close of such exchanges
or, lacking any sales, at the last available bid price. Assets
for which market quotations are not readily available are valued
at fair value on a consistent basis using methods determined in
good faith by the Fund's Board of Directors, including valuations
furnished by a pricing service retained by the Fund, which may
utilize a matrix system for valuations.
<PAGE> 165
(b)Financial futures contracts--The National and Limited
Maturity Portfolios (the "Portfolios") may purchase or sell interest
rate futures contracts and options on such futures contracts for the 
purpose of hedging the market risk on existing 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 Portfolios deposit
and maintain as collateral such initial margin as required by the
exchange on which the transaction is effected. Pursuant to the
contract, the Portfolios agree 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 Portfolios as unrealized gains or
losses. When the contract is closed, the Portfolios record a
realized gain or loss equal to the difference between the value
of the contract at the time it was opened and the value at the
time it was closed.

(c)Income taxes--It is the Fund's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated
investment companies and to distribute substantially all of its 
taxable income to its shareholders. Therefore, no Federal income 
tax provision is required.

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

(e) Deferred organization expenses and prepaid registration
fees--Deferred organization expenses are charged to expenses on a
straight-line basis over a five-year period. Costs related to the
organization of the second class of shares are charged to expense
over a period not exceeding five years. Prepaid registration fees
are charged to expenses 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.

2. Investment Advisory Agreement and Transactions
with Affiliates:
The Fund has entered into an Investment Advisory Agreement with
Fund Asset Management, L.P. ("FAM"). Effective January 1, 1994
the investment advisory business of FAM was reorganized from a
corporation to a limited partnership. Both prior to and after the
reorganization, ultimate control of FAM was vested with Merrill
Lynch & Co., Inc. ("ML & Co."). The general partner of FAM is 
Princeton Services, Inc., an indirect wholly-owned subsidiary 
of ML & Co. The limited partners are ML & Co. and Fund Asset 
Management, Inc. ("FAMI"), which is also an indirect wholly-owned 
subsidiary of ML & Co. The Fund also entered into Distribution 
Agreements and a Distribution Plan with Merrill Lynch Funds 
Distributor, Inc. ("MLFD" or the "Distributor"), a wholly-owned 
subsidiary of Merrill Lynch Investment Management, Inc.

FAM is responsible for the management of the Fund's Portfolios
and provides the necessary personnel, facilities, equipment and
certain other services necessary to the operations of the Fund.
For such services, FAM receives at the end of each month a fee
with respect to each Portfolio at the annual rates set forth
below which are based upon the average daily value of the Fund's
net assets.

In excess of $400 million but not 
exceeding $550 million                0.375       0.475      0.35  
In excess of $550 million but not 
exceeding $1.5 billion                0.375       0.475      0.325 
In excess of $1.5 billion             0.35        0.475      0.325 


The Investment Advisory Agreement obligates FAM to reimburse the
Fund to the extent that 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 Fund's next $70 million
of average daily net assets, and 1.5% of the average daily net
assets in excess thereof. No fee payment will be made to FAM with
respect to any Portfolio during any fiscal year which will cause 
the expenses of such Portfolio to exceed the pro rata expense 
limitation applicable to such Portfolio at the time of such payment.

The Fund has adopted a Plan of Distribution (the "Plan") pursuant
to Rule 12b-1 under the Investment Company Act of 1940 pursuant
to which MLFD receives a distribution fee from the Fund for the sale
of Class B Shares of the Portfolios at the end of each month at
the annual rate of 0.50% (in the case of the Insured Portfolio
and the National Portfolio) or 0.25% (in the case of the Limited
Maturity Portfolio) and an account maintenance fee at the annual
rate of 0.25% (in the case of the Insured Portfolio and the
National Portfolio) or 0.10% (in the case of the Limited Maturity 
Portfolio) of the average daily net assets of the Class B Shares 
of the respective Portfolios. Pursuant to a sub-agreement with the 
Distributor, Merrill Lynch also provides the account maintenance 
and distribution services to the Fund. The ongoing account maintenance 
fee compensates the Distributor and Merrill Lynch for providing 
account maintenance services to Class B shareholders. This fee is 
to compensate the Distributor for services provided and the expenses 
borne by it under the Plan. As authorized by the Plan, the Distributor 
has entered into an agreement with Merrill Lynch, Pierce, Fenner &
Smith Inc. ("MLPF&S"), an affiliate of Merrill Lynch Investment
Management, Inc., which provides for the compensation of MLPF&S
for providing distribution-related services to the Fund.

For the year ended June 30, 1994, MLFD earned underwriting
discounts, and MLPF&S earned dealer concessions on sales of the
Fund's Class A Shares as follows:

relating to transactions in Class B Shares, amounting to
$1,469,123, $718,890 and $190,903 in the Insured, National and 
Limited Maturity Portfolios, respectively.

Financial Data Services, Inc. ("FDS"), 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 directors of the Fund are officers and/or
directors of FAM, FAMI, MLFD, FDS, MLPF&S, and/or ML & Co.

                                 CLASS A SHARES
                         AMENDED DISTRIBUTION AGREEMENT

            AGREEMENT  made as of the 19th day of  September,  1979 and  amended
this 21st day of October,  1994 between MERRILL LYNCH MUNICIPAL BOND FUND, INC.,
a Maryland corporation (the "Fund"), and MERRILL LYNCH FUNDS DISTRIBUTOR,  INC.,
a Delaware corporation (the "Distributor").

                             W I T N E S S E T H :
            WHEREAS,  the Fund is engaged in business as a diversified  open-end
investment  company and is registered under the Investment  Company Act of 1940,
as  amended  (the  "Investment  Company  Act")  and it is  affirmatively  in the
interest  of the Fund to offer its shares for sale  continuously  pursuant  to a
currently effective prospectus under the Securities Act of 1933, as amended (the
"Securities Act"); and
            WHEREAS, the Fund is comprised of three separate Portfolios, each of
which pursues its investment objective through separate investment policies; and
            WHEREAS,  the  Distributor  is a  securities  firm  engaged  in  the
business of selling shares of investment companies either directly to purchasers
or through other securities dealers; and
            WHEREAS,  the  Fund  and  the  Distributor  wish  to  enter  into an
agreement with each other with respect to the  continuous  offering of shares of
the Class A Common Stock of the Fund's three  Portfolios in order to promote the
growth of the Fund and facilitate the distribution of its shares.




<PAGE>



            NOW, THEREFORE, the parties agree as follows:
            Section 1. Appointment of the Distributor.  The Fund hereby appoints
the Distributor as the principal underwriter and distributor of the Fund to sell
shares of Class A Common  Stock of each of the Fund's  three  Portfolios  (which
shares are collectively  referred to herein as "shares") to the public. The Fund
hereby agrees to sell shares of the Fund to the  Distributor  during the term of
this Agreement upon the terms and conditions herein set forth.
            Section 2. Exclusive Nature of Duties.  The Distributor shall be the
exclusive  representative  of  the  Fund  to act as  principal  underwriter  and
distributor, except that:
            (a) The Fund may, upon written notice to the Distributor,  from time
      to time designate other  principal  underwriters  and  distributors of its
      shares with respect to areas other than the United  States as to which the
      Distributor may have expressly waived in writing its right to act as such.
      If such  designation  is deemed  exclusive,  the right of the  Distributor
      under  this  Agreement  to sell  shares in the areas so  designated  shall
      terminate,  but this Agreement shall remain otherwise in full effect until
      terminated in accordance with the other provisions hereof.
            (b) The  exclusive  rights  granted to the  Distributor  to purchase
      shares  from the Fund  shall not  apply to  shares  of the Fund  issued in
      connection  with the  merger  or  consolidation  of any  other  investment
      company or personal  holding  company with the Fund or the  acquisition by
      purchase or otherwise of all



                                      2

<PAGE>



      (or substantially all) the assets  or the  outstanding shares  of any such
      company by the Fund.
            (c) Such  exclusive  rights shall also not apply to shares issued by
      the  Fund  pursuant  to   reinvestment   of  dividends  or  capital  gains
      distributions.
            (d) Such  exclusive  rights shall also not apply to shares issued by
      the  Fund  pursuant  to the  reinstatement  privilege  afforded  redeeming
      shareholders.
            Section 3.        Purchase of Shares from the Fund.

            (a) The Fund  will  offer  its  Class A shares  and  thereafter  the
Distributor shall have the right to buy from the Fund the Class A shares needed,
but not more than the shares needed (except for clerical errors in transmission)
to fill unconditional  orders for shares of the Fund placed with the Distributor
by investors or securities  dealers.  The price which the Distributor  shall pay
for the  shares of any  Portfolio  so  purchased  from the Fund shall be the net
asset value, determined as set forth in Section 3(d) hereof, used in determining
the public offering price on which such orders were based.
            (b) The shares are to be resold by the  Distributor  to investors at
the public offering price, as set forth in Section 3(d) hereof, or to securities
dealers having agreements with the Distributor upon the terms and conditions set
forth in Section 7 hereof.
            (c) The public  offering  price(s) of the shares of each  Portfolio,
i.e., the price per share at which the Distributor or selected  dealers may sell
shares to the public, shall be the public



                                      3

<PAGE>



offering price as set forth in the currently effective prospectus of the
Fund under the Securities Act (the "prospectus"), relating to such shares, but
not to exceed the net asset value at which the Distributor is to purchase the
shares, plus a sales charge not to exceed 4.00% of the public offering price
(4.17% of the net amount invested) for the National and Insured Portfolios and
1.00% of the offering price (1.01% of the net amount invested) of the Limited
Maturity Portfolio, subject to reductions for volume purchases. Shares may be
sold to employees of Merrill Lynch & Co., Inc. and its subsidiaries without a
sales charge upon terms and conditions set forth in the prospectus. If the
public offering price does not equal an even cent, the public offering price may
be adjusted to the nearest cent. All payments to the Fund hereunder shall be
made in the manner set forth in Section 3(f).
            (d) The net  asset  value  of  shares  of each  Portfolio  shall  be
determined by the Fund or any agent of the Fund, as of the close of the New York
Stock  Exchange  on each  business  day on  which  said  Exchange  is  open,  in
accordance  with  the  method  set  forth  in the  prospectus  of the  Fund  and
guidelines  established by the Board of Directors of the Fund. The Fund may also
cause the net asset value to be determined in  substantially  the same manner or
estimated  in such manner and as of such other hour or hours as may from time to
time be agreed upon in writing by the Fund and the Distributor.
            (e) The Fund shall have the right to suspend  the sale of its shares
at times when  redemption is suspended  pursuant to the  conditions set forth in
Section 4(b) hereof. The Fund shall also



                                      4

<PAGE>



have the right to  suspend  the sale of its  shares if  trading  on the New York
Stock Exchange shall have been  suspended,  if a banking  moratorium  shall have
been  declared by Federal or New York  authorities,  or if there shall have been
some other  extraordinary  event,  which, in the judgment of the Fund,  makes it
impracticable to sell the shares.
            (f) The Fund, or any agent of the Fund  designated in writing by the
Fund,  shall be promptly  advised of all purchase  orders for shares received by
the Distributor.  Any order may be rejected by the Fund; provided, however, that
the Fund will not  arbitrarily or without  reasonable  cause refuse to accept or
confirm orders for the purchase of shares.  The Fund (or its agent) will confirm
orders upon their receipt,  will make appropriate book entries and, upon receipt
by the Fund (or its agent) of payment therefor, will deliver deposit receipts or
certificates  for such shares pursuant to the  instructions of the  Distributor.
Payment  shall  be made to the  Fund  in New  York  Clearing  House  funds.  The
Distributor  agrees to cause such payment and such  instructions to be delivered
promptly to the Fund (or its agent).
            Section 4.        Repurchase or Redemption of Shares by the Fund.
            (a) Any of the outstanding  shares may be tendered for redemption at
any time,  and the Fund agrees to repurchase or redeem the shares so tendered in
accordance  with its  obligations as set forth in Article VII of its Articles of
Incorporation,  as  amended  from  time to  time,  and in  accordance  with  the
applicable  provisions  set forth in the prospectus of the Fund. The price to be
paid to



                                      5

<PAGE>



redeem or repurchase the shares shall be equal to the net asset value calculated
in accordance  with the  provisions of Section 3(e) hereof.  All payments by the
Fund  hereunder  shall be made in the manner set forth below.  The redemption or
repurchase  by the  Fund  of  any of the  shares  purchased  by or  through  the
Distributor  will not affect the sales charge secured by the  Distributor or any
selected  dealer in the course of the original  sale,  except that if any shares
are tendered for  redemption or repurchase  within seven business days after the
date of the confirmation of the original purchase, the right to the sales charge
shall be forfeited by the  Distributor  and the selected  dealer which sold such
shares.
            The Fund  shall pay the  total  amount  of the  redemption  price as
defined in the above paragraph  pursuant to the  instructions of the Distributor
in New  York  Clearing  House  funds  on or  before  the  seventh  business  day
subsequent to its having received the notice of redemption in proper form.
            (b)  Redemption  of shares or payment may be suspended at times when
the New York Stock Exchange is closed,  when trading on said Exchange is closed,
when  trading on said  Exchange is  restricted,  when an  emergency  exists as a
result of which disposal by the Fund of securities owned by it is not reasonably
practicable or it is not reasonably practicable for the Fund fairly to determine
the value of the net assets of its  Portfolios,  or during any other period when
the Securities and Exchange Commission, by order, so permits.

            Section 5.        Duties of the Fund.
            (a)  The  Fund  shall  furnish  to  the  Distributor  copies  of all
information,  financial  statements and other papers which the  Distributor  may
reasonably  request for use in connection with the distribution of shares of the
Fund,  and  this  shall  include  one  certified   copy,  upon  request  by  the
Distributor,  of all financial  statements  prepared for the Fund by independent
public accountants. The Fund shall make available to the Distributor such number
of copies of its prospectus as the Distributor shall reasonably request.
            (b) The Fund shall  take,  from time to time,  such action as may be
necessary to register the shares of each Portfolio  under the Securities Act, to
the end that  there  will be  available  for sale  such  number of shares as the
Distributor reasonably may be expected to sell.
            (c) The Fund shall use its best  efforts to qualify and maintain the
qualification  of an  appropriate  number of shares of each  Portfolio  for sale
under the  securities  laws of such states as the  Distributor  and the Fund may
approve. Any such qualification may be withheld,  terminated or withdrawn by the
Fund at any time in its  discretion.  As provided in Section  8(c)  hereof,  the
expense of qualification and maintenance of qualification  shall be borne by the
Fund. The Distributor shall furnish such information and other material relating
to its affairs and activities as may be required by the Fund in connection  with
such qualification.



                                      7

<PAGE>



            (d) The Fund will furnish, in reasonable  quantities upon request by
the Distributor, copies of annual and interim reports of the Fund.
            Section 6.        Duties of the Distributor.
            (a) The  Distributor  shall  devote  reasonable  time and  effort to
effect  sales of  shares of the Fund,  but  shall not be  obligated  to sell any
specific number of shares. The services of the Distributor to the Fund hereunder
are not to be deemed  exclusive and nothing herein  contained  shall prevent the
Distributor from entering into like arrangements with other investment companies
so long as the  performance  of  their  obligations  hereunder  is not  impaired
thereby.
            (b) In selling the shares of the Fund, the Distributor shall use its
best  efforts in all  respects  duly to  conform  with the  requirements  of all
federal  and state laws  relating  to the sale of such  securities.  Neither the
Distributor  nor any selected  dealer nor any other person is  authorized by the
Fund to give any  information or to make any  representations,  other than those
contained  in the  registration  statement or related  prospectus  and any sales
literature specifically approved by the Fund.
            (c) The Distributor shall adopt and follow  procedures,  as approved
by the officers of the Fund,  for the  confirmation  of sales to  investors  and
selected  dealers,  the collection of amounts  payable by investors and selected
dealers on such sales, and the cancellation of unsettled transactions, as may be
necessary to comply with the requirements of the National Association of



                                      8

Securities Dealers, Inc. (the "NASD"),  as such  requirements  may from  time to
time exist.
            Section 7.  Selected Dealers Agreement.
            (a) The  Distributor  shall  have the right to enter  into  selected
dealers  agreements with securities  dealers of its choice ("selected  dealers")
for the sale of shares and fix therein the portion of the sales charge which may
be allocated to the selected  dealers;  provided that the Fund shall approve the
forms of agreements with dealers and the dealer  compensation  set forth therein
and shall evidence such approval by filing said forms and amendments  thereto as
exhibits to its currently  effective  registration  statement on Form N-1A filed
under the Securities Act. Shares sold to selected dealers shall be for resale by
such dealers only at the public  offering  price(s) set forth in the prospectus.
The initial form of agreement with selected dealers to be used in the continuous
offering of the shares is attached hereto as Exhibit A.
            (b) Within the United States,  the Distributor  shall offer and sell
shares only to selected dealers which are members on good standing of the NASD.
            Section 8. Payment of Expenses.
            (a) The  Fund  shall  bear  all  costs  and  expenses  of the  Fund,
including fees and disbursements of its counsel and auditors, in connection with
the  preparation  and  filing of any  required  registration  statements  and/or
prospectuses  under the  Investment  Company  Act, the  Securities  Act, and all
amendments and supplements thereto, and preparing and mailing annual and interim
reports and



                                      9

<PAGE>



proxy  materials to  shareholders  (including  but not limited to the expense of
setting  in type any  such  registration  statements,  prospectuses,  annual  or
interim reports or proxy materials).
            (b) After the  prospectuses and annual and interim reports have been
prepared and set in type, the  Distributor  shall bear the costs and expenses of
printing and  distributing any copies thereof which are to be used in connection
with the offering of shares to selected  dealers or investors.  The  Distributor
shall bear the costs and expenses of preparing,  printing and  distributing  any
other  literature used by the Distributor or furnished by it for use by selected
dealers in connection with the offering of the shares for sale to the public and
any expenses of advertising in connection with such offering.
            (c) Each Portfolio shall bear the cost of expenses of  qualification
of the shares for sale, and, if necessary or advisable in connection  therewith,
of  qualifying  the Fund as a broker or  dealer,  in such  states of the  United
States  or  other  jurisdictions  as  shall  be  selected  by the  Fund  and the
Distributor pursuant to Section 5(c) hereof and the cost and expenses payable to
each such state for continuing  qualification  therein until the Fund decides to
discontinue such qualification pursuant to Section 5(c) hereof.
            Section 9.        Indemnification.
            (a) The Fund shall  indemnify and hold harmless the  Distributor and
each person, if any, who controls the Distributor  against any loss,  liability,
claim,  damage or expense  (including the reasonable  cost of  investigating  or
defending any alleged loss,



                                      10

<PAGE>



liability,  claim,  damage or expense and  reasonable  counsel fees  incurred in
connection  therewith),  arising by reason of any person  acquiring  any shares,
which may be based upon the Securities Act, or on any other statute or at common
law, on the ground that the  registration  statement or related  prospectus,  as
from time to time amended and supplemented,  or the annual or interim reports to
shareholders  of the Fund,  includes an untrue  statement of a material  fact or
omits to state a material  fact  required to be stated  therein or  necessary in
order to make the statements  therein not  misleading,  unless such statement or
omission  was  made  in  reliance  upon,  and in  conformity  with,  information
furnished  to  the  Fund  in  connection  therewith  by  or  on  behalf  of  the
Distributor; provided, however, that in no case (i) is the indemnity of the Fund
in favor of the  Distributor  and any such  controlling  persons to be deemed to
protect such  Distributor or any such  controlling  persons  thereof against any
liability to the Fund or its security  holders to which the  Distributor  or any
such  controlling  persons  would  otherwise  be  subject  by reason of  willful
misfeasance, bad faith or gross negligence in the performance of their duties or
by reason of the reckless  disregard of their  obligations and duties under this
Agreement,  or (ii) is the  Fund to be  liable  under  its  indemnity  agreement
contained  in  this  paragraph  with  respect  to any  claim  made  against  the
Distributor  or any such  controlling  persons,  unless the  Distributor or such
controlling persons, as the case may be, shall have notified the Fund in writing
within a reasonable  time after the summons or other first legal process  giving
information of the nature of the claim shall have been served upon



                                      11

<PAGE>



the  Distributor or such  controlling  persons (or after the Distributor or such
controlling persons shall have received notice of such service on any designated
agent),  but  failure to notify the Fund of any such claim  shall not relieve it
from any liability  which it may have to the person  against whom such action is
brought otherwise than on account of its indemnity  agreement  contained in this
paragraph.  The Fund will be entitled to  participate  at its own expense in the
defense,  or, if it so  elects,  to assume the  defense  of any suit  brought to
enforce any such liability,  but if the Fund elects to assume the defense,  such
defense  shall be  conducted  by counsel  chosen by it and  satisfactory  to the
Distributor or such  controlling  person or persons,  defendant or defendants in
the suit.  In the event the Fund  elects to assume the  defense of any such suit
and retain such counsel,  the Distributor or such controlling person or persons,
defendant  or  defendants  in the suit,  shall bear the fees and expenses of any
additional  counsel  retained  by them,  but, in case the Fund does not elect to
assume the defense of any such suit, it will  reimburse the  Distributor or such
controlling  person or persons,  defendant or  defendants  in the suit,  for the
reasonable  fees and  expenses of any counsel  retained by them.  The Fund shall
promptly  notify  the  Distributor  of the  commencement  of any  litigation  or
proceedings  against it or any of its officers or directors in  connection  with
the issuance or sale of any of the shares.
            (b) The  Distributor  shall indemnify and hold harmless the Fund and
each of its  directors  and officers  and each person,  if any, who controls the
Fund against any loss, liability, claim,



                                      12

<PAGE>



damage or expense described in the foregoing  indemnity  contained in subsection
(a) of this Section,  but only with respect to  statements or omissions  made in
reliance  upon,  and in conformity  with,  information  furnished to the Fund in
writing  by or on  behalf  of the  Distributor  for use in  connection  with the
registration  statement or related prospectus,  as from time to time amended, or
the  annual or  interim  reports to  shareholders.  In case any action  shall be
brought  against  the Fund or any  person so  indemnified,  in  respect of which
indemnity may be sought against the Distributor,  the Distributor shall have the
rights and duties given to the Fund, and the Fund and each person so indemnified
shall have the rights and duties given to the  Distributor  by the provisions of
subsection (a) of this Section 9.
            Section 10. Merrill Lynch Mutual Fund Adviser Program. In connection
with the Merrill  Lynch Mutual Fund Adviser  Program,  the  Distributor  and its
affiliate, Merrill Lynch, Pierce, Fenner & Smith Incorporated, are authorized to
offer and sell shares of the Fund,  as agent for the Fund,  to  participants  in
such program.  The terms of this Agreement  shall apply to such sales, including
terms as to offering  price of shares,  the proceeds to be paid to the Fund, the
duties  of  the  Distributor,   the  payment  of  expenses  and  indemnification
obligations of the Fund and the Distributor.
            Section  11.  Duration  and  Termination  of  this  Agreement.  This
Agreement  shall become  effective as of the date first above  written and shall
remain in force until October 21, 1996 and thereafter as to any  Portfolio,  but
only so long as such  continuance is specifically  approved at least annually by
(i) the



                                      13

<PAGE>



Board of Directors of the Fund, or by the vote of a majority of the  outstanding
shares of that Portolio,  and  (ii)  a majority of those  directors who are not 
parties to this Agreement or interested persons of any such party cast in person
at a meeting called for the purpose of voting on such approval.
            This Agreement may be terminated at any time, without the payment of
any  penalty,  by the Board of Directors of the Fund or by vote of a majority of
the  outstanding  shares  of the Fund,  or by the  Distributor,  on sixty  days'
written notice to the other party. This Agreement shall automatically  terminate
in the event of its assignment.
            Section 12.  Amendments  of this  Agreement.  This  Agreement may be
amended  by  the  parties  as  to  any  Portfolio  only  if  such  amendment  is
specifically  approved by (i) the Board of Directors of the Fund, or by the vote
of a  majority  of  outstanding  voting  securities  of that Portfolio, and (ii)
a majority of those directors of the Fund who are not parties to this  Agreement
or interested  persons of any such party cast in person at a meeting  called for
the purpose of voting on such approval.
            Section 13. Definitions. The terms "assignment," "affiliated person"
and "interested person," when used in this Agreement,  shall have the respective
meanings  specified in the  Investment  Company Act. As used with respect to the

                           SELECTED DEALERS AGREEMENT


Gentlemen:

            Merrill Lynch Funds  Distributor,  Inc. (the  "Distributor")  has an

(the  "Fund"),  pursuant  to  which it acts as the  distributor  for the sale of
shares  of Class A  Insured  Portfolio  Series  Common  Stock,  Class A  Limited
Maturity  Portfolio  Series Common Stock and Class A National  Portfolio  Series
Common Stock,  par value $0.10 per share, of the Fund, and as such has the right
to distribute shares of the Fund for resale. The Fund is a diversified  open-end
investment  company  registered  under the  Investment  Company Act of 1940,  as
amended,  and its shares being  offered to the public are  registered  under the
Securities Act of 1933, as amended. You have received a copy of the Distribution
Agreement  between  ourself and the Fund and reference is made herein to certain
provisions of such  Distribution  Agreement.  The term Prospectus as used herein
refers to the  prospectus on file with the  Securities  and Exchange  Commission
which is part of the most recent effective  registration  statement  pursuant to
the Securities Act of 1933, as amended.  As principal,  we offer to sell to you,
as a member of the Selected Dealers Group, shares of the Fund upon the following
terms and conditions:

            1. In all  sales of these  shares  to the  public  you  shall act as
dealer for your own account, and in no transaction shall you




<PAGE>



have any authority to act as agent for the Fund,  for us or for any other member
of the Selected  Dealers  Group,  except in  connection  with the Merrill  Lynch
Mutual Fund Adviser  program and such other special  programs as we from time to
time agree, in which case you shall have authority to offer and sell shares,  as
agent for the Fund, to participants in such program.

             2. Orders received from you will be accepted through us only as the
public  offering  price  applicable  to each order,  as set forth in the current
Prospectus of the Fund.  The procedure  relating to the handling of orders shall
be  subject  to  Section 5 hereof  and  instructions  which we or the Fund shall
forward  from time to time to you.  All orders  are  subject  to  acceptance  or
rejection by the Distributor or the Fund in the sole  discretion of either.  The
minimum initial and subsequent purchase requirements are set forth in the 
current prospectus and Statement of Additional Information of the Fund.

            3.  The  sales  charges  for  sales  to  the  public,   computed  as

**   Initial sales charges may be waived for certain  classes of offerees as set

     Such purchases may be subject to a contingent  deferred sales charge as set
     forth in the current Prospectus and Statement of Additional Information.

            The term "purchase" refers to a single purchase by an individual, or
to  concurrent  purchases,  which in the  aggregate  are at  least  equal to the
prescribed  amounts,  by an individual,  his spouse and their children under the
age of 21 years purchasing



                                      3

<PAGE>



shares  for his or their own  account  and to single  purchases  by a trustee or
other fiduciary  purchasing shares for a single trust estate or single fiduciary
account although more than one beneficiary is involved. The term "purchase" also
includes  purchases by any  "company" as that term is defined in the  Investment
Company Act of 1940,  as amended,  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.

            The  reduced  sales  charges  are  applicable  through  a  right  of
accumulation  under which investors are permitted to purchase shares of the Fund
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 hold-
ings of the shares of the Fund and of any other investment  company with a sales
charge for which the Distributor  acts as the  distributor. For any such right 
of accumulation to be made available, the Distributor  must be  provided at the
time of purchase, by the purchaser or you, with sufficient



                                      4

<PAGE>



information  to permit  confirmation  of  qualification,  and  acceptance of the
purchase order is subject to such confirmation.

            The reduced  sales  charges are  applicable  to  purchases of shares
through you aggregating  $25,000 or more for the Insured and National Portfolios
or  $100,000  or  more  for  the  Limited  Maturity   Portfolio  made  within  a
thirteen-month  period starting with the first purchase  pursuant to a Letter of
Intention in the form provided in the Prospectus. A purchase not originally made
pursuant to a Letter of  Intention  may be included  under a  subsequent  letter
executed  within 90 days of such  purchase  if the  Distributor  is  informed in
writing of this intent  within such 90-day  period.  If the  intended  amount of
shares is not purchased within the  thirteen-month  period, an appropriate price
adjustment will be made pursuant to the terms of the Letter of Intention.

            You agree to advise us  promptly at our request as to amounts of any
sales made by you to the public  qualifying for reduced sales  charges.  Further
information  as  to  the  reduced  sales  charges   pursuant  to  the  right  of
accumulation or a Letter of Intention is set forth in the Prospectus.

             4. You shall not place orders for any of the shares unless you have
already  received  purchase  orders  for such  shares at the  applicable  public
offering  prices  and  subject  to the  terms  hereof  and  of the  Distribution
Agreement.  You agree that you will not offer or sell any of the  shares  except
under circumstances that



                                      5

<PAGE>



will result in compliance with the applicable  Federal and state securities laws
and that in connection  with sales and offers to sell shares you will furnish to
each person to whom any such sale or offer is made a copy of the  Prospectus (as
then amended or supplemented) and will not furnish to any person any information
relating to the shares of the Fund,  which is  inconsistent  in any respect with
the information contained in the Prospectus (as then amended or supplemented) or
cause any advertisement to be published in any newspaper or posted in any public
place without our consent and the consent of the Fund.

             5. As a selected  dealer,  you are hereby  authorized  (i) to place
orders  directly  with the Fund for shares of the Fund to be resold by us to you
subject to the applicable terms and conditions governing the placement of orders
by us set forth in Section 3 of the  Distribution  Agreement  and subject to the
compensation  provisions of Section 3 hereof, and (ii) to tender shares directly
to the Fund or its agent for  redemption  subject  to the  applicable  terms and
conditions set forth in Section 4 of the Distribution Agreement.

             6. You  shall  not  withhold  placing  orders  received  from  your
customers so as to profit yourself as a result of such  withholding:  e.g., by a
change in the "net asset value" from that used in determining the offering price
to your customers.




                                      6

<PAGE>



             7. If any shares sold to you under the terms of this  Agreement are
repurchased by the Fund or by us for the account of the Fund or are tendered for
redemption  within seven business days after the date of the confirmation of the
original purchase by you, it is agreed that you shall forfeit your right to, and
refund to us, any discount received by you on such shares.

             8. No person is authorized to make any  representations  concerning
shares of the issuer  except those  contained in the current  Prospectus  of the
Fund and in such printed  information  subsequently  issued by us or the Fund as
information supplemental to such Prospectus. In purchasing shares through us you
shall  rely  solely  on the  representations  contained  in the  Prospectus  and
supplemental  information  above  mentioned.  Any printed  information  which we
furnish  you  other  than the  Fund's  Prospectus,  periodic  reports  and proxy
solicitation  material are our sole responsibility and not the responsibility of
the Fund, and you agree that the Fund shall have no liability or  responsibility
to you in these respects unless expressly assumed in connection therewith.

             9. You agree to deliver to each of the purchasers  making purchases
from  you a copy of the  then  current  Prospectus  at or  prior  to the time of
offering or sale and you agree  thereafter to deliver to such purchasers  copies
of the annual and interim reports and proxy solicitation  materials of the Fund.
You further agree to endeavor to obtain proxies from such purchasers. Additional
copies of the Prospectus, annual or interim reports and



                                      7

<PAGE>



proxy  solicitation  materials of the Fund will be supplied to you in reasonable
quantities upon request.

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

            11. We shall have full  authority to take such action as we may deem
advisable in respect of all matters  pertaining to the continuous  offering.  We
shall  be under no  liability  to you  except  for  lack of good  faith  and for
obligations expressly assumed by us herein.  Nothing contained in this paragraph
is intended to operate as, and the provisions of this paragraph shall not in any
way whatsoever  constitute,  a waiver by you of compliance with any provision of
the Securities Act of 1933, as amended,  or of the rules and  regulations of the
Securities and Exchange Commission issued thereunder.

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

            13. Upon  application  to us, we will inform you as to the states in
which we believe the shares have been  qualified  for sale under,  or are exempt
from the requirements of, the respective



                                      8

<PAGE>


securities laws of such states, but we assume no responsibility or obligation as
to your  right  to sell  shares  in any  jurisdiction.  We will  file  with  the
Department  of State in New York a Further  State  Notice  with  respect  to the
shares, if necessary.

            14. All communications to us should be sent to the address set forth
below.  Any notice to you shall be duly given if mailed or telegraphed to you at
the address specified by you below.

            15.  Your first order  placed  pursuant  to this  Agreement  for the
purchase of shares of the Fund will represent your acceptance of this Agreement.

                             DISTRIBUTION AGREEMENT


            AGREEMENT made as of the 21st day of October 1994,  between  MERRILL
LYNCH  MUNICIPAL  BOND FUND,  INC., a Maryland  corporation  (the  "Fund"),  and
MERRILL   LYNCH  FUNDS   DISTRIBUTOR,   INC.,   a  Delaware   corporation   (the
"Distributor").

                             W I T N E S S E T H :


            WHEREAS,  the Fund is registered under the Investment Company Act of
1940,  as amended (the  "Investment  Company  Act"),  as an open-end  investment
company, and it is affirmatively in the interest of the Fund to offer its shares
for sale continuously; and
            WHEREAS, the Fund is comprised of three separate portfolios, namely,
the Insured Portfolio, the National Portfolio and the Limited Maturity Portfolio
(the "Portfolios"),  each of which pursues its own investment  objective through
separate investment policies; and
            WHEREAS,  the  Distributor  is a  securities  firm  engaged  in  the
business of selling shares of investment companies either directly to purchasers
or through other securities dealers; and
            WHEREAS,  the  Fund  and  the  Distributor  wish  to  enter  into an
agreement with each other with respect to the continuous  offering of the shares
of the Class C Insured  Portfolio  Series  Common  Stock,  the Class C  National
Portfolio Series Common Stock and the Class C Limited Maturity  Portfolio Series
Common  Stock of the Fund  (collectively,  the  "Class C  shares"  ) in order to
promote







<PAGE>



the growth of the Fund and facilitate the distribution of its Class C shares.
            NOW, THEREFORE, the parties agree as follows:
            Section 1. Appointment of the Distributor.  The Fund hereby appoints
the Distributor as the principal underwriter and distributor of the Fund to sell
Class C shares of common  stock in the Fund  (sometimes  herein  referred  to as
"Class C  shares")  to the  public  and  hereby  agrees  during the term of this
Agreement  to sell  shares  of the Fund to the  Distributor  upon the  terms and
conditions herein set forth.
            Section 2. Exclusive Nature of Duties.  The Distributor shall be the
exclusive  representative  of  the  Fund  to act as  principal  underwriter  and
distributor of the Class C shares, except that:
            (a) The Fund may, upon written notice to the Distributor,  from time
to time designate  other  principal  underwriters  and  distributors  of Class C
shares  with  respect  to areas  other  than the  United  States as to which the
Distributor  may have  expressly  waived in writing its right to act as such. If
such designation is deemed  exclusive,  the right of the Distributor  under this
Agreement to sell Class C shares in the areas so designated shall terminate, but
this  Agreement  shall  remain  otherwise  in full effect  until  terminated  in
accordance with the other provisions hereof.
            (b) The exclusive right granted to the Distributor to purchase Class
C shares  from the Fund shall not apply to Class C shares of the Fund  issued in
connection with the merger or conso-






                                       2

<PAGE>



lidation of any other  investment  company or personal  holding company with the
Fund or the acquisition by purchase or otherwise of all (or  substantially  all)
the assets or the outstanding Class C shares of any such company by the Fund.
            (c) Such  exclusive  right  also  shall  not apply to Class C shares
issued by the Fund  pursuant  to  reinvestment  of  dividends  or capital  gains
distributions.
            (d) Such  exclusive  right  also  shall  not apply to Class C shares
issued  by the  Fund  pursuant  to any  conversion,  exchange  or  reinstatement
privilege  afforded  redeeming  shareholders  or to any other  Class C shares as
shall be agreed between the Fund and the Distributor from time to time.
            Section 3.  Purchase of Class C Shares from the Fund.
            (a) It is  contemplated  that the Fund will  commence an offering of
its Class C shares,  and thereafter the Distributor  shall have the right to buy
from the Fund the Class C shares of each Portfolio needed, but not more than the
Class C  shares  of  each  Portfolio  needed  (except  for  clerical  errors  in
transmission)  to fill  unconditional  orders for Class C shares of the relevant
Portfolio  placed with the  Distributor  by  eligible  investors  or  securities
dealers.  Investors  eligible to purchase Class C shares of a Portfolio shall be
those persons so identified in the currently effective  prospectus and statement
of  additional  information  of the Fund (the  "prospectus"  and  "statement  of
additional  information",  respectively)  under the  Securities  Act of 1933, as
amended (the "Securities Act"), relating to such Class C shares. The price which
the Distributor shall pay for the Class C






                                       3

<PAGE>



shares of a Portfolio  so  purchased  from the Fund shall be the net asset value
for that Portfolio, determined as set forth in Section 3(c) hereof.
            (b) The  Class C  shares  of a  Portfolio  are to be  resold  by the
Distributor to investors at net asset value for that Portfolio,  as set forth in
Section  3(c)  hereof,  or to  securities  dealers  having  agreements  with the
Distributor upon the terms and conditions set forth in Section 7 hereof.
            (c) The net asset  value of Class C shares of a  Portfolio  shall be
determined  by the Fund or any agent of the Fund in  accordance  with the method
set  forth  in the  prospectus  and  statement  of  additional  information  and
guidelines established by the Board of Directors.
            (d) The Fund  shall  have the right to  suspend  the sale of Class C
shares of any Portfolio at times when  redemption  is suspended  pursuant to the
conditions set forth in Section 4(b) hereof.  The Fund shall also have the right
to  suspend  the sale of Class C shares of any  Portfolio  if trading on the New
York Stock Exchange shall have been  suspended,  if a banking  moratorium  shall
have been  declared by Federal or New York  authorities,  or if there shall have
been  some  other  event,   which,  in  the  judgment  of  the  Fund,  makes  it
impracticable or inadvisable to sell the Class C shares.
            (e) The Fund, or any agent of the Fund  designated in writing by the
Fund,  shall be  promptly  advised  of all  purchase  orders  for Class C shares
received by the  Distributor.  Any order may be rejected by the Fund;  provided,
however, that the Fund will






                                       4

<PAGE>



not arbitrarily or without  reasonable  cause refuse to accept or confirm orders
for the purchase of Class C shares.  The Fund (or its agent) will confirm orders
upon their receipt,  will make appropriate book entries and, upon receipt by the
Fund (or its  agent) of payment  therefor,  will  deliver  deposit  receipts  or
certificates  for  such  Class C  shares  pursuant  to the  instructions  of the
Distributor. Payment shall be made to the Fund in New York Clearing House funds.
The  Distributor  agrees  to cause  such  payment  and such  instructions  to be
delivered promptly to the Fund (or its agent).
            Section 4. Repurchase or Redemption of Class C Shares by the Fund.
            (a)  Any of the  outstanding  Class C  shares  may be  tendered  for
redemption at any time,  and the Fund agrees to repurchase or redeem the Class C
shares so tendered in accordance  with its  obligations  as set forth in Article
VII of its  Articles  of  Incorporation,  as amended  from time to time,  and in
accordance  with the  applicable  provisions  set  forth in the  prospectus  and
statement of additional  information of the Fund. The price to be paid to redeem
or repurchase the Class C shares of a Portfolio  shall be equal to the net asset
value for that Portfolio calculated in accordance with the provisions of Section
3(c) hereof, less any contingent deferred sales charge ("CDSC"),  redemption fee
or other  charge(s),  if any,  set  forth in the  prospectus  and  statement  of
additional  information of the Fund. All payments by the Fund hereunder shall be
made in the manner set forth below.
            The Fund  shall pay the  total  amount  of the  redemption  price as
defined in the above paragraph pursuant to the






                                       5

<PAGE>



instructions of the Distributor on or before the seventh business day subsequent
to its having  received the notice of redemption in proper form. The proceeds of
any  redemption  of  shares  shall  be paid  by the  Fund  as  follows:  (i) any
applicable CDSC shall be paid to the Distributor,  and (ii) the balance shall be
paid to or for the account of the  shareholder,  in each case in accordance with
the  applicable  provisions  of  the  prospectus  and  statement  of  additional
information.
            (b)  Redemption of Class C shares of any Portfolio or payment may be
suspended at times when the New York Stock  Exchange is closed,  when trading on
said Exchange is suspended, when trading on said Exchange is restricted, when an
emergency  exists as a result of which disposal by the Fund of securities  owned
by it is not reasonably  practicable or it is not reasonably practicable for the
Fund fairly to determine the value of its net assets, or during any other period
when the Securities and Exchange Commission, by order, so permits.
            Section 5.  Duties of the Fund.
            (a)  The  Fund  shall  furnish  to  the  Distributor  copies  of all
information,  financial  statements and other papers which the  Distributor  may
reasonably request for use in connection with the distribution of Class C shares
of the Fund,  and this  shall  include,  upon  request by the  Distributor,  one
certified copy of all financial  statements prepared for the Fund by independent
public accountants. The Fund shall make available to the Distributor such number
of copies of its  prospectus  and  statement of  additional  information  as the
Distributor shall reasonably request.






                                       6

<PAGE>



            (b) The Fund  shall  take,  from time to time,  but  subject  to any
necessary  approval of the shareholders,  all necessary action to fix the number
of  authorized  shares and such steps as may be  necessary  to register the same
under the  Securities  Act to the end that there will be available for sale such
number of Class C shares as the Distributor reasonably may be expected to sell.
            (c) The Fund shall use its best  efforts to qualify and maintain the
qualification of an appropriate  number of its Class C shares for sale under the
securities laws of such states as the Distributor and the Fund may approve.  Any
such  qualification may be withheld,  terminated or withdrawn by the Fund at any
time in its  discretion.  As provided  in Section  8(c)  hereof,  the expense of
qualification  and maintenance of qualification  shall be borne by the Fund. The
Distributor  shall furnish such  information and other material  relating to its
affairs and  activities as may be required by the Fund in  connection  with such
qualification.
            (d) The Fund will furnish, in reasonable  quantities upon request by
the Distributor, copies of annual and interim reports of the Fund.
            Section 6.  Duties of the Distributor.
            (a) The  Distributor  shall  devote  reasonable  time and  effort to
effect  sales of Class C shares of the Fund but shall not be  obligated  to sell
any  specific  number of shares.  The  services of the  Distributor  to the Fund
hereunder are not to be deemed  exclusive  and nothing  herein  contained  shall
prevent the Distributor from entering into like arrangements with other in-






                                       7

<PAGE>



vestment  companies so long as the performance of its  obligations  hereunder is
not impaired thereby.
            (b) In selling the Class C shares of the Fund, the Distributor shall
use its best efforts in all respects  duly to conform with the  requirements  of
all Federal and state laws relating to the sale of such securities.  Neither the
Distributor  nor any selected  dealer,  as defined in Section 7 hereof,  nor any
other person is  authorized by the Fund to give any  information  or to make any
representations,  other than those  contained in the  registration  statement or
related  prospectus  and  statement  of  additional  information  and any  sales
literature specifically approved by the Fund.
            (c) The Distributor shall adopt and follow  procedures,  as approved
by the officers of the Fund,  for the  confirmation  of sales to  investors  and
selected  dealers,  the collection of amounts  payable by investors and selected
dealers on such sales, and the cancellation of unsettled transactions, as may be
necessary  to  comply  with the  requirements  of the  National  Association  of
Securities  Dealers,  Inc. (the "NASD"),  as such  requirements may from time to
time exist.
            Section 7.  Selected Dealer Agreements.
            (a) The  Distributor  shall  have the right to enter  into  selected
dealer agreements with securities dealers of its choice ("selected dealers") for
the sale of Class C shares;  provided,  that the Fund shall approve the forms of
agreements  with dealers.  Class C shares sold to selected  dealers shall be for
resale  by such  dealers  only at net  asset  value  determined  as set forth in
Section






                                       8

<PAGE>



3(c) hereof.  The form of agreement with selected  dealers to be used during the
continuous offering of the shares is attached hereto as Exhibit A.
            (b) Within the United States,  the Distributor  shall offer and sell
Class C shares only to such  selected  dealers that are members in good standing
of the NASD.
            Section 8.  Payment of Expenses.
            (a) The  Fund  shall  bear  all  costs  and  expenses  of the  Fund,
including fees and disbursements of its counsel and auditors, in connection with
the  preparation  and  filing of any  required  registration  statements  and/or
prospectuses  and  statements of  additional  information  under the  Investment
Company Act, the Securities Act, and all amendments and supplements thereto, and
preparing and mailing annual and interim  reports and proxy materials to Class C
shareholders  (including  but not  limited to the expense of setting in type any
such   registration   statements,   prospectuses,   statements   of   additional
information, annual or interim reports or proxy materials).
            (b) The  Distributor  shall be responsible  for any payments made to
selected dealers as reimbursement for their expenses associated with payments of
sales commissions to financial consultants. In addition, after the prospectuses,
statements of additional  information  and annual and interim  reports have been
prepared and set in type, the  Distributor  shall bear the costs and expenses of
printing and  distributing any copies thereof which are to be used in connection
with the offering of Class C shares to selected dealers or investors pursuant to
this Agreement. The






                                       9

<PAGE>



Distributor  shall  bear the costs  and  expenses  of  preparing,  printing  and
distributing any other literature used by the Distributor or furnished by it for
use by selected  dealers in  connection  with the offering of the Class C shares
for  sale  to the  public  and  any  expenses  of  advertising  incurred  by the
Distributor in connection  with such offering.  It is understood and agreed that
so long as the Fund's Class C Shares  Distribution  Plan  pursuant to Rule 12b-1
under the Investment Company Act remains in effect, any expenses incurred by the
Distributor  hereunder  may be paid from  amounts  recovered by it from the Fund
under such Plan.
            (c) Each Portfolio shall bear the cost and expenses of qualification
of the Class C shares for sale pursuant to this  Agreement  and, if necessary or
advisable in connection therewith,  of qualifying the Fund as a broker or dealer
in such states of the United States or other  jurisdictions as shall be selected
by the Fund and the Distributor pursuant to Section 5(c) hereof and the cost and
expenses payable to each such state for continuing  qualification  therein until
the Fund  decides to  discontinue  such  qualification  pursuant to Section 5(c)
hereof.
            Section 9.  Indemnification.
            (a) The Fund shall  indemnify and hold harmless the  Distributor and
each person, if any, who controls the Distributor  against any loss,  liability,
claim,  damage or expense  (including the reasonable  cost of  investigating  or
defending any alleged loss,  liability,  claim, damage or expense and reasonable
counsel fees incurred in connection therewith),  as incurred,  arising by reason
of any person acquiring any Class C shares, which may be based upon






                                       10

<PAGE>



the Securities Act, or on any other statute or at common law, on the ground that
the  registration  statement or related  prospectus  and statement of additional
information,  as from time to time  amended  and  supplemented,  or an annual or
interim report to Class C shareholders of the Fund, includes an untrue statement
of a  material  fact or omits to state a  material  fact  required  to be stated
therein or necessary  in order to make the  statements  therein not  misleading,
unless such  statement or omission was made in reliance  upon, and in conformity
with,  information furnished to the Fund in connection therewith by or on behalf
of the Distributor;  provided,  however, that in no case (i) is the indemnity of
the Fund in favor of the  Distributor  and any such  controlling  persons  to be
deemed to protect  such  Distributor  or any such  controlling  persons  thereof
against  any  liability  to the  Fund  or its  security  holders  to  which  the
Distributor or any such controlling persons would otherwise be subject by reason
of willful  misfeasance,  bad faith or gross  negligence in the  performance  of
their duties or by reason of the reckless  disregard  of their  obligations  and
duties  under  this  Agreement;  or (ii)  is the  Fund to be  liable  under  its
indemnity  agreement  contained in this paragraph with respect to any claim made
against the Distributor or any such controlling persons,  unless the Distributor
or such controlling persons, as the case may be, shall have notified the Fund in
writing within a reasonable  time after the summons or other first legal process
giving  information  of the nature of the claim  shall have been served upon the
Distributor  or such  controlling  persons  (or  after the  Distributor  or such
controlling persons shall have received notice






                                       11

<PAGE>



of such service on any designated  agent), but failure to notify the Fund of any
such  claim  shall not  relieve it from any  liability  which it may have to the
person  against  whom such  action is brought  otherwise  than on account of its
indemnity  agreement  contained in this paragraph.  The Fund will be entitled to
participate at its own expense in the defense or, if it so elects, to assume the
defense  of any suit  brought  to enforce  any such  liability,  but if the Fund
elects to assume the defense,  such defense shall be conducted by counsel chosen
by it and satisfactory to the Distributor or such controlling person or persons,
defendant or  defendants in the suit. In the event the Fund elects to assume the
defense  of any such suit and  retain  such  counsel,  the  Distributor  or such
controlling  person or persons,  defendant or  defendants in the suit shall bear
the fees and expenses,  as incurred, of any additional counsel retained by them,
but in case the Fund does not elect to assume the  defense of any such suit,  it
will reimburse the Distributor or such controlling person or persons,  defendant
or defendants in the suit, for the reasonable fees and expenses, as incurred, of
any counsel  retained by them. The Fund shall promptly notify the Distributor of
the  commencement  of any  litigation  or  proceedings  against it or any of its
officers or  Directors  in  connection  with the  issuance or sale of any of the
Class C shares.
            (b) The  Distributor  shall indemnify and hold harmless the Fund and
each of its  Directors  and officers  and each person,  if any, who controls the
Fund  against  any loss,  liability,  claim,  damage or  expense,  as  incurred,
described  in the  foregoing  indemnity  contained  in  subsection  (a) of  this
Section, but only with






                                       12

<PAGE>



respect to  statements  or omissions  made in reliance  upon,  and in conformity
with,  information  furnished  to the Fund in  writing  by or on  behalf  of the
Distributor  for use in connection  with the  registration  statement or related
prospectus  and  statement  of  additional  information,  as  from  time to time
amended,  or the annual or interim reports to  shareholders.  In case any action
shall be brought  against the Fund or any person so  indemnified,  in respect of
which indemnity may be sought against the  Distributor,  the  Distributor  shall
have the rights and duties  given to the Fund,  and the Fund and each  person so
indemnified  shall have the rights and duties  given to the  Distributor  by the
provisions of subsection (a) of this Section 9.
            Section 10.  Duration and Termination of this Agreement.
            This  Agreement  shall  become  effective as of the date first above
written and shall remain in force until  October 21, 1996 and  thereafter  as to
any Portfolio, but only for so long as such continuance is specifically approved
at least  annually  by (i) the  Directors  or by the vote of a  majority  of the
outstanding  voting  securities  of that  Portfolio  and  (ii) by the  vote of a
majority of those  Directors who are not parties to this Agreement or interested
persons of any such party cast in person at a meeting  called for the purpose of
voting on such approval.
            This Agreement may be terminated at any time, without the payment of
any penalty, by the Directors or by vote of a majority of the outstanding voting
securities of the Fund, or by the Distributor,  on sixty days' written notice to
the other party.

This Agreement shall automatically terminate in the event of its assignment.
            The terms "vote of a majority of the outstanding voting securities",
"assignment",  "affiliated  person" and "interested  person",  when used in this
Agreement,  shall  have the  respective  meanings  specified  in the  Investment
Company Act.
            Section 11.  Amendments  of this  Agreement.  This  Agreement may be
amended  as  to  any  Portfolio  by  the  parties  only  if  such  amendment  is
specifically  approved by (i) the Board of  Directors of the Fund or by the vote
of a majority of outstanding  voting  securities  that Portfolio of the Fund and
(ii) by the  vote of a  majority  of  those  Directors  of the  Fund who are not
parties to this Agreement or interested persons of any such party cast in person
at a meeting called for the purpose of voting on such approval.
            Section 12. Governing Law. The provisions of this Agreement shall be
construed and  interpreted in accordance  with the laws of the State of New York

                    MERRILL LYNCH MUNICIPAL BOND FUND, INC.

                         CLASS C SHARES OF COMMON STOCK

                           SELECTED DEALER AGREEMENT

Gentlemen:

            Merrill Lynch Funds  Distributor,  Inc. (the  "Distributor")  has an
agreement with MERRILL LYNCH MUNICIPAL BOND FUND,  INC., a Maryland  corporation
(the  "Fund"),  pursuant  to  which it acts as the  distributor  for the sale of
shares  of Class C Insured  Portfolio  Series  Common  Stock,  Class C  National
Portfolio  Series  Common Stock and Class C Limited  Maturity  Portfolio  Series
Common Stock par value $0.10 per share  (collectively the "Class C shares"),  of
the Fund and as such has the right to distribute  Class C shares of the Fund for
resale.  The  Fund  is an  open-end  investment  company  registered  under  the
Investment Company Act of 1940, as amended, and its Class C shares being offered
to the public are registered  under the Securities Act of 1933, as amended.  You
have  received  a  copy  of the  Class  C  Shares  Distribution  Agreement  (the
"Distribution  Agreement")  between  ourself and the Fund and  reference is made
herein  to  certain  provisions  of  such  Distribution  Agreement.   The  terms
"Prospectus"  and "Statement of Additional  Information" as used herein refer to
the prospectus and statement of additional  information,  respectively,  on file
with the  Securities  and Exchange  Commission  which is part of the most recent
effective  registration  statement  pursuant to the  Securities  Act of 1933, as
amended.  We offer to sell to you, as a member of the  Selected  Dealers  Group,
Class C shares of the Fund upon the following terms and conditions:

            1. In all sales of these Class C shares to the public, you shall act
as  dealer  for  your  own  account  and in no  transaction  shall  you have any
authority  to act as agent for the Fund,  for us or for any other  member of the
Selected Dealers Group.

            2. Orders received from you will be accepted  through us only at the
public  offering  price  applicable  to each order,  as set forth in the current
Prospectus  and Statement of Additional  Information  of the Fund. The procedure
relating  to the  handling  of orders  shall be  subject to Section 4 hereof and
instructions  which we or the Fund shall  forward  from time to time to you. All
orders are subject to acceptance or rejection by the  Distributor or the Fund in
the sole discretion of either. The minimum initial and







<PAGE>



subsequent purchase  requirements are as set forth in the current Prospectus and
Statement of Additional Information of the Fund.

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

            4. As a  selected  dealer,  you are hereby  authorized  (i) to place
orders  directly with the Fund for Class C shares of the Fund to be resold by us
to you subject to the applicable terms and conditions governing the placement of
orders by us set forth in Section 3 of the  Distribution  Agreement  and (ii) to
tender Class C shares  directly to the Fund or its agent for redemption  subject
to  the  applicable  terms  and  conditions  set  forth  in  Section  4  of  the
Distribution Agreement.

            5.  You  shall  not  withhold  placing  orders  received  from  your
customers so as to profit yourself as a result of such with- holding: e.g., by a
change in the "net asset value" from that used in determining the offering price
to your customers.

            6. No person is  authorized to make any  representations  concerning
Class C shares of the Fund except those contained in the current  Prospectus and
Statement of Additional  Information of the Fund and in such printed information
subsequently  issued  by us or the  Fund  as  information  supplemental  to such
Prospectus and Statement of Additional Information. In purchasing Class C shares
through  us you  shall  rely  solely  on the  representations  contained  in the
Prospectus and Statement of Additional Information and supplemental  information
above  mentioned.  Any printed  information  which we furnish you other than the
Fund's  Prospectus,  Statement of Additional  Information,  periodic reports and
proxy   solicitation   material   is  our  sole   responsibility   and  not  the
responsibility  of the Fund, and you agree that the Fund shall have no liability
or  responsibility  to  you  in  these  respects  unless  expressly  assumed  in
connection therewith.

            7. You agree to deliver to each of the purchasers  making  purchases
from you a copy of the then current Prospectus






                                       2

<PAGE>

and, if requested,  the Statement of Additional  Information  at or prior to the
time of offering or sale and you agree  thereafter to deliver to such purchasers
copies of the annual and interim reports and proxy solicitation materials of the
Fund.  You further  agree to endeavor to obtain  proxies  from such  purchasers.
Additional  copies of the  Prospectus  and Statement of Additional  Information,
annual or interim reports and proxy  solicitation  materials of the Fund will be
supplied to you in reasonable quantities upon request.

            8. We  reserve  the  right in our  discretion,  without  notice,  to
suspend sales or withdraw the offering of Class C shares  entirely or to certain
persons or entities in a class or classes specified by us. Each party hereto has
the right to cancel this Agreement upon notice to the other party.

            9. We shall have full  authority  to take such action as we may deem
advisable in respect of all matters  pertaining to the continuous  offering.  We
shall  be under no  liability  to you  except  for  lack of good  faith  and for
obligations expressly assumed by us herein.  Nothing contained in this paragraph
is intended to operate as, and the provisions of this paragraph shall not in any
way whatsoever  constitute,  a waiver by you of compliance with any provision of
the Securities Act of 1933, as amended,  or of the rules and  regulations of the
Securities and Exchange Commission issued thereunder.

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

            11. Upon  application  to us, we will inform you as to the states in
which we believe the Class C shares have been  qualified for sale under,  or are
exempt from the requirements of, the respective  securities laws of such states,
but we assume no  responsibility  or obligation as to your right to sell Class C
shares in any  jurisdiction.  We will file with the  Department  of State in New
York a Further State Notice with respect to the Class C shares, if necessary.

            12. All  communications  to us should be sent to the address  below.
Any  notice to you shall be duly  given if mailed or  telegraphed  to you at the
address specified by you below.

            13.  Your first order  placed  pursuant  to this  Agreement  for the

Agreement.

                                CLASS D SHARES

                            DISTRIBUTION AGREEMENT


      AGREEMENT made as of the 21st day of October,  1994 between  MERRILL LYNCH
MUNICIPAL  BOND FUND,  INC., a Maryland  corporation  (the "Fund"),  and MERRILL
LYNCH FUNDS DISTRIBUTOR, INC., a Delaware corporation (the "Distributor").

                            W I T N E S S E T H :

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

      WHEREAS, the Fund is comprised of three separate  portfolios,  namely, the
Insured  Portfolio,  the National  Portfolio and the Limited Maturity  Portfolio
(the "Portfolios"),  each of which pursues its own investment  objective through
separate investment policies; and

      WHEREAS,  the  Distributor is a securities firm engaged in the business of
selling shares of investment  companies either directly to purchasers or through
other securities dealers; and




<PAGE>



      WHEREAS, the Fund and the Distributor wish to enter into an agreement with
each  other  with  respect  to the  continuous  offering  of the Class D Insured
Portfolio  Series Common  Stock,  the Class D National  Portfolio  Series Common
Stock and the Class D Limited Maturity Portfolio Series Common Stock of the Fund
(collectively,  the "Class D shares") in order to promote growth of the Fund and
facilitate the distribution of its Class D shares.
      NOW, THEREFORE, the parties agree as follows:
      Section 1.  Appointment of the  Distributor.  The Fund hereby appoints the
Distributor  as the principal  underwriter  and  distributor of the Fund to sell
Class D shares of common  stock in the Fund  (sometimes  herein  referred  to as
"Class D  shares")  to the  public  and  hereby  agrees  during the term of this
Agreement to sell Class D shares of the Fund to the  Distributor  upon the terms
and conditions herein set forth.
      Section  2.  Exclusive  Nature of  Duties.  The  Distributor  shall be the
exclusive  representative  of  the  Fund  to act as  principal  underwriter  and
distributor of its Class D shares, except that:
      (a) The Fund may,  upon written  notice to the  Distributor,  from time to
time designate other principal  underwriters  and distributors of Class D shares
with respect to areas other than the United  States as to which the  Distributor
may  have  expressly  waived  in  writing  its  right  to act as  such.  If such
designation  is  deemed  exclusive,  the  right of the  Distributor  under  this
Agreement to sell Class D shares in the areas so designated shall terminate, but



                                      2

<PAGE>



this  Agreement  shall  remain  otherwise  in full effect  until  terminated  in
accordance with the other provisions hereof.
      (b) The exclusive  right granted to the  Distributor  to purchase  Class D
shares from the Fund shall not apply to Class D shares issued in connection with
the merger or consolidation of any other investment  company or personal holding
company  with the Fund or the  acquisition  by purchase or  otherwise of all (or
substantially  all) the  assets  or the  outstanding  Class D shares of any such
company by the Fund.
      (c) Such exclusive  right also shall not apply to Class D shares issued by
the Fund pursuant to reinvestment of dividends or capital gains distributions.
      (d) Such exclusive  right also shall not apply to Class D shares issued by
the  Fund  pursuant  to any  conversion,  exchange  or  reinstatement  privilege
afforded  redeeming  shareholders  or to any  other  Class D shares  as shall be
agreed between the Fund and the Distributor from time to time.
      Section 3.  Purchase of Class D Shares from the Fund.
      (a)  It is contemplated that the Fund will commence an
offering of its Class D shares,  and thereafter the  Distributor  shall have the
right to buy from the Fund  the  Class D shares  needed,  but not more  than the
Class D shares  needed  (except for  clerical  errors in  transmission)  to fill
unconditional  orders for Class D shares of the Fund placed with the Distributor
by eligible  investors or  securities  dealers.  Investors  eligible to purchase
Class D shares shall be those persons so identified in the



                                      3

<PAGE>



currently  effective  prospectus and statement of additional  information of the
Fund (the "prospectus" and "statement of additional information",  respectively)
under the Securities Act of 1933, as amended (the "Securities Act"), relating to
such Class D shares.  The price which the Distributor  shall pay for the Class D
shares so purchased  from the Fund shall be the net asset value,  determined  as
set forth in Section 3(d) hereof,  used in determining the public offering price
on which such orders were based.
      (b) The Class D shares are to be resold by the Distributor to investors at
the public offering price, as set forth in Section 3(c) hereof, or to securities
dealers having agreements with the Distributor upon the terms and conditions set
forth in Section 7 hereof.
      (c) The public  offering  price(s) of the Class D shares,  i.e., the price
per share at which the  Distributor or selected  dealers may sell Class D shares
to the public, shall be the public offering price as set forth in the prospectus
and statement of additional information relating to such Class D shares, but not
to exceed the net asset value at which the  Distributor is to purchase the Class
D shares,  plus a sales charge not to exceed 4.00% of the public  offering price
(4.17% of the net amount  invested) for the Insured and National  Portfolios and
1.00% of the public  offering  price (1.01% of the net amount  invested) for the
Limited Maturity Portfolio,  subject to reductions for volume purchases. Class D
shares may be sold to certain  Directors,  officers and  employees of the Fund,
of Merrill Lynch & Co., Inc. and



                                      4

<PAGE>



its subsidiaries, and their directors and employees and to certain other persons
described  in  the prospectus and statement of  additional  information, without
a sales  charge or at a reduced sales  charge,  upon  terms  and  conditions set
forth in the  prospectus and statement of additional information.  If the public
offering price does not equal an even  cent,  the  public offering price may be 
adjusted to the nearest cent. All payments to the Fund  hereunder  shall be made
in the manner set forth in Section 3(f).
      (d) The net asset value of Class D shares shall be  determined by the Fund
or any  agent  of the  Fund in  accordance  with  the  method  set  forth in the
prospectus  and statement of additional  information  of the Fund and guidelines
established by the Board of Directors of the Fund.
      (e) The Fund  shall  have the  right to  suspend  the sale of its  Class D
shares at times when  redemption  is suspended  pursuant to the  conditions  set
forth in Section 4(b) hereof.  The Fund shall also have the right to suspend the
sale of its Class D shares if trading on the New York Stock  Exchange shall have
been suspended,  if a banking  moratorium shall have been declared by Federal or
New York  authorities,  or if there shall have been some other event,  which, in
the judgment of the Fund,  makes it  impracticable  or  inadvisable  to sell the
Class D shares.
      (f) The Fund, or any agent of the Fund  designated in writing by the Fund,
shall be promptly  advised of all purchase orders for Class D shares received by
the Distributor.  Any order may be rejected by the Fund; provided, however, that
the Fund will not



                                      5

<PAGE>



arbitrarily or without  reasonable  cause refuse to accept or confirm orders for
the purchase of Class D shares. The Fund (or its agent) will confirm orders upon
their receipt,  will make appropriate book entries and, upon receipt by the Fund
(or  its  agent)  of  payment   therefor,   will  deliver  deposit  receipts  or
certificates  for  such  Class D  shares  pursuant  to the  instructions  of the
Distributor. Payment shall be made to the Fund in New York Clearing House funds.
The  Distributor  agrees  to cause  such  payment  and such  instructions  to be
delivered promptly to the Fund (or its agent).
      Section 4. Repurchase or Redemption of Class D Shares by the Fund.
      (a) Any of the  outstanding  Class D shares may be tendered for redemption
at any time,  and the Fund agrees to  repurchase or redeem the Class D shares so
tendered in accordance  with its  obligations as set forth in Article VII of its
Articles of Incorporation,  as amended from time to time, and in accordance with
the  applicable  provisions  set  forth  in  the  prospectus  and  statement  of
additional information. The price to be paid to redeem or repurchase the Class D
shares shall be equal to the net asset value  calculated in accordance  with the
provisions of Section 3(d) hereof,  less any  contingent  deferred  sales charge
("CDSC"), redemption fee or other charge(s), if any, set forth in the prospectus
and statement of additional  information  of the Fund.  All payments by the Fund
hereunder  shall be made in the  manner  set  forth  below.  The  redemption  or
repurchase by the Fund of any of the Class D shares  purchased by or through the
Distributor will not affect the sales



                                      6

<PAGE>



charge secured by the  Distributor  or any selected  dealer in the course of the
original sale,  except that if any Class D shares are tendered for redemption or
repurchase  within seven business days after the date of the confirmation of the
original  purchase,  the right to the sales  charge  shall be  forfeited  by the
Distributor and the selected dealer which sold such Class D shares.
      The Fund shall pay the total amount of the redemption  price as defined in
the above paragraph  pursuant to the instructions of the Distributor in New York
Clearing  House funds on or before the seventh  business day  subsequent  to its
having  received the notice of  redemption  in proper form.  The proceeds of any
redemption  of shares shall be paid by the Fund as follows:  (i) any  applicable
CDSC shall be paid to the Distributor,  and (ii) the balance shall be paid to or
for the  account  of the  shareholder,  in  each  case in  accordance  with  the
applicable provisions of the prospectus and statement of additional information.
      (b) Redemption of Class D shares or payment may be suspended at times when
the New York  Stock  Exchange  is  closed,  when  trading  on said  Exchange  is
suspended, when trading on said Exchange is restricted, when an emergency exists
as a result  of which  disposal  by the  Fund of  securities  owned by it is not
reasonably  practicable or it is not reasonably  practicable for the Fund fairly
to  determine  the value of its net assets,  or during any other period when the
Securities and Exchange Commission, by order, so permits.

      Section 5.  Duties of the Fund.
      (a) The Fund shall furnish to the Distributor  copies of all  information,
financial  statements  and other papers  which the  Distributor  may  reasonably
request for use in  connection  with the  distribution  of Class D shares of the
Fund, and this shall  include,  upon request by the  Distributor,  one certified
copy of all financial  statements  prepared for the Fund by  independent  public
accountants.  The Fund shall make  available to the  Distributor  such number of
copies  of  the  prospectus  and  statement  of  additional  information  as the
Distributor shall reasonably request.
      (b) The Fund shall take,  from time to time,  but subject to any necessary
approval of the Class D shareholders,  all necessary action to fix the number of
authorized  Class D shares and such steps as may be  necessary  to register  the
same under the Securities  Act, to the end that there will be available for sale
such number of Class D shares as the  Distributor  may reasonably be expected to
sell.
      (c) The Fund  shall use its best  efforts  to  qualify  and  maintain  the
qualification of an appropriate  number of its Class D shares for sale under the
securities laws of such states as the Distributor and the Fund may approve.  Any
such  qualification may be withheld,  terminated or withdrawn by the Fund at any
time in its  discretion.  As provided  in Section  8(c)  hereof,  the expense of
qualification  and maintenance of qualification  shall be borne by the Fund. The
Distributor shall furnish such information and other



                                      8

<PAGE>



material  relating to its affairs and  activities as may be required by the Fund
in connection with such qualification.
      (d) The Fund will furnish,  in reasonable  quantities  upon request by the
Distributor, copies of annual and interim reports of the Fund.

      Section 6.  Duties of the Distributor.
      (a) The  Distributor  shall  devote  reasonable  time and effort to effect
sales of Class D shares  of the Fund  but  shall  not be  obligated  to sell any
specific  number of Class D shares.  The services of the Distributor to the Fund
hereunder are not to be deemed  exclusive  and nothing  herein  contained  shall
prevent  the  Distributor  from  entering  into  like  arrangements  with  other
investment companies so long as the performance of its obligations  hereunder is
not impaired thereby.
      (b) In selling the Class D shares of the Fund, the  Distributor  shall use
its best efforts in all respects  duly to conform with the  requirements  of all
Federal  and state laws  relating  to the sale of such  securities.  Neither the
Distributor  nor any selected  dealer,  as defined in Section 7 hereof,  nor any
other person is  authorized by the Fund to give any  information  or to make any
representations,  other than those  contained in the  registration  statement or
related  prospectus  and  statement  of  additional  information  and any  sales
literature specifically approved by the Fund.



                                      9

      (c) The Distributor shall adopt and follow procedures,  as approved by the
officers of the Fund,  for the  confirmation  of sales to investors and selected
dealers,  the collection of amounts payable by investors and selected dealers on
such sales, and the cancellation of unsettled transactions,  as may be necessary
to comply  with the  requirements  of the  National  Association  of  Securities
Dealers, Inc. (the "NASD"), as such requirements may from time to time exist.
      Section 7.  Selected Dealers Agreements.
      (a) The  Distributor  shall have the right to enter into selected  dealers
agreements with securities  dealers of its choice  ("selected  dealers") for the
sale of Class D shares and fix therein the portion of the sales charge which may
be allocated to the selected  dealers;  provided that the Fund shall approve the
forms of agreements with dealers and the dealer  compensation set forth therein.
Class D shares sold to selected dealers shall be for resale by such dealers only
at the public  offering  price(s) set forth in the  prospectus  and statement of
additional  information.  The form of agreement with selected dealers to be used
during  the  continuous  offering  of the Class D shares is  attached  hereto as
Exhibit A.
      (b) Within the United States, the Distributor shall offer and sell Class D
shares  only to such  selected  dealers as are  members in good  standing of the
NASD.

      Section 8.  Payment of Expenses.
      (a) The Fund shall bear all costs and expenses of the Fund, including fees
and  disbursements  of  its  counsel  and  auditors,   in  connection  with  the
preparation  and  filing  of  any  required   registration   statements   and/or
prospectuses  and  statements of  additional  information  under the  Investment
Company Act, the Securities Act, and all amendments and supplements thereto, and
preparing and mailing annual and interim  reports and proxy materials to Class D
shareholders  (including  but not  limited to the expense of setting in type any
such   registration   statements,   prospectuses,   statements   of   additional
information, annual or interim reports or proxy materials).
      (b) The Distributor shall be responsible for any payments made to selected
dealers as  reimbursement  for their expenses  associated with payments of sales
commissions  to  financial  consultants.  In addition,  after the  prospectuses,
statements of additional  information  and annual and interim  reports have been
prepared and set in type, the  Distributor  shall bear the costs and expenses of
printing and  distributing any copies thereof which are to be used in connection
with the offering of Class D shares to selected dealers or investors pursuant to
this Agreement.  The Distributor shall bear the costs and expenses of preparing,
printing  and  distributing  any other  literature  used by the  Distributor  or
furnished by it for use by selected  dealers in connection  with the offering of
the  Class D shares  for sale to the  public  and any  expenses  of  advertising
incurred by the Distributor



                                      11

<PAGE>



in connection  with such  offering.  It is understood and agreed that so long as
the Fund's  Class D Shares  Distribution  Plan  pursuant to Rule 12b-1 under the
Investment  Company  Act  remains  in  effect,  any  expenses  incurred  by  the
Distributor  hereunder in connection with account maintenance  activities may be
paid from amounts recovered by it from the Fund under such Plan.
      (c) Each Portfolio  shall bear the cost and expenses of  qualification  of
the Class D shares for sale  pursuant to this  Agreement  and, if  necessary  or
advisable in connection therewith,  of qualifying the Fund as a broker or dealer
in such states of the United States or other  jurisdictions as shall be selected
by the Fund and the Distributor pursuant to Section 5(c) hereof and the cost and
expenses payable to each such state for continuing  qualification  therein until
the Fund  decides to  discontinue  such  qualification  pursuant to Section 5(c)
hereof.
      Section 9.  Indemnification.
      (a) The Fund shall  indemnify and hold harmless the  Distributor  and each
person, if any, who controls the Distributor against any loss, liability, claim,
damage or expense  (including the reasonable cost of  investigating or defending
any alleged loss,  liability,  claim,  damage or expense and reasonable  counsel
fees incurred in connection  therewith),  as incurred,  arising by reason of any
person acquiring any Class D shares, which may be based upon the Securities Act,
or on any other  statute or at common law,  on the ground that the  registration
statement or related prospectus and statement of additional information, as from
time to time



                                      12

<PAGE>



amended and supplemented,  or an annual or interim report to shareholders of the
Fund,  includes  an  untrue  statement  of a  material  fact or omits to state a
material  fact  required to be stated  therein or necessary in order to make the
statements therein not misleading, unless such statement or omission was made in
reliance  upon,  and in conformity  with,  information  furnished to the Fund in
connection therewith by or on behalf of the Distributor; provided, however, that
in no case (i) is the indemnity of the Fund in favor of the  Distributor and any
such  controlling  persons to be deemed to protect such  Distributor or any such
controlling  persons  thereof  against any liability to the Fund or its security
holders to which the Distributor or any such controlling persons would otherwise
be subject by reason of willful  misfeasance,  bad faith or gross  negligence in
the performance of their duties or by reason of the reckless  disregard of their
obligations  and duties under this  Agreement;  or (ii) is the Fund to be liable
under its indemnity  agreement  contained in this  paragraph with respect to any
claim made against the Distributor or any such controlling  persons,  unless the
Distributor or such controlling persons, as the case may be, shall have notified
the Fund in writing  within a  reasonable  time after the summons or other first
legal  process  giving  information  of the nature of the claim  shall have been
served  upon  the  Distributor  or  such  controlling   persons  (or  after  the
Distributor  or such  controlling  persons  shall have  received  notice of such
service on any  designated  agent),  but  failure to notify the Fund of any such
claim shall not relieve it from any liability



                                      13

<PAGE>



which it may have to the person  against  whom such action is brought  otherwise
than on account of its indemnity agreement contained in this paragraph. The Fund
will be entitled to  participate  at its own expense in the defense or, if it so
elects, to assume the defense of any suit brought to enforce any such liability,
but if the Fund elects to assume the defense, such defense shall be conducted by
counsel chosen by it and  satisfactory  to the  Distributor or such  controlling
person or persons,  defendant or  defendants  in the suit. In the event the Fund
elects to assume  the  defense  of any such suit and retain  such  counsel,  the
Distributor or such  controlling  person or persons,  defendant or defendants in
the suit shall bear the fees and expenses of any additional  counsel retained by
them,  but in case the Fund  does not elect to assume  the  defense  of any such
suit, it will reimburse the Distributor or such  controlling  person or persons,
defendant or defendants in the suit, for the reasonable fees and expenses of any
counsel  retained by them. The Fund shall promptly notify the Distributor of the
commencement of any litigation or proceedings  against it or any of its officers
or  Directors  in  connection  with the  issuance  or sale of any of the Class D
shares.
      (b) The Distributor shall indemnify and hold harmless the Fund and each of
its  Directors  and  officers  and each  person,  if any,  who controls the Fund
against any loss, liability, claim, damage or expense described in the foregoing
indemnity contained in subsection (a) of this Section,  but only with respect to
statements or omissions made in reliance upon, and in conformity with,



                                      14

<PAGE>



information  furnished to the Fund in writing by or on behalf of the Distributor
for use in connection with the registration  statement or related prospectus and
statement of additional information, as from time to time amended, or the annual
or interim reports to Class D shareholders.  In case any action shall be brought
against the Fund or any person so indemnified, in respect of which indemnity may
be sought against the  Distributor,  the  Distributor  shall have the rights and
duties given to the Fund, and the Fund and each person so indemnified shall have
the rights and duties given to the  Distributor  by the provisions of subsection
(a) of this Section 9.
      Section 10. Merrill Lynch Mutual Fund Adviser Program.  In connection with
the  Merrill  Lynch  Mutual  Fund  Adviser  Program,  the  Distributor  and  its
affiliate, Merrill Lynch, Pierce, Fenner & Smith Incorporated, are authorized to
offer and sell shares of the Fund,  as agent for the Fund,  to  participants  in
such program.  The terms of this Agreement  shall apply to such sales, including
terms as to offering  price of shares,  the proceeds to be paid to the Fund, the
duties  of  the  Distributor,   the  payment  of  expenses  and  indemnification
obligations of the Fund and the Distributor.
      Section 11.  Duration and  Termination of this  Agreement.  This Agreement
shall become  effective  as of the date first above  written and shall remain in
force  until  October  21,  1996  and  thereafter,  but only for so long as such
continuance  is  specifically  approved as to a Portfolio at least  annually
by  (i) the Board  of  Directors or by the vote of a majority of the outstanding
voting  securities of that Portfolio and



                                      15

<PAGE>



(ii) by the vote of a majority  of those  Directors  who are not parties to this
Agreement  or  interested  persons of any such party cast in person at a meeting
called for the purpose of voting on such approval.
      This  Agreement may be terminated as to a Portfolio at any time,  without 
the payment of any penalty,  by the Directors or by vote of a majority of the
outstanding  Class D voting  securities  of the that Portfolio, or by the  
Distributor,  on sixty days' written notice to the other party. This Agreement
shall  automatically  terminate in the event of its assignment.
      The terms  "vote of a  majority  of the  outstanding  voting  securities",
"assignment",  "affiliated  person" and "interested  person",  when used in this
Agreement,  shall  have the  respective  meanings  specified  in the  Investment
Company Act.
      Section 12. Amendments of this Agreement. This Agreement may be amended by
the parties only if such amendment is specifically approved as to a Portfolio by
(i)  the  Board of Directors or by the vote of a majority of outstanding  voting
securities of that  Portfolio and   (ii)  by the vote of a majority of those
Directors  of the  Fund who are not  parties  to  this  Agreement or  interested
persons of any such  party cast in person at a meeting called for the purpose of
voting on such approval.
      Section 13.  Governing  Law. The  provisions  of this  Agreement  shall be
construed and  interpreted in accordance  with the laws of the State of New York
as at the time in effect and the applicable provisions of the Investment Company
Act. To the extent that the



                                      16

<PAGE>



applicable  law of the  State  of New  York,  or any of the  provisions  herein,
conflict  with the  applicable  provisions  of the  Investment  Company Act, the
latter shall control.

                          SELECTED DEALER AGREEMENT


Gentlemen:

      Merrill Lynch Funds Distributor, Inc. (the "Distributor") has an agreement
with  Merrill  Lynch  Municipal  Bond Fund,  Inc., a Maryland  corporation  (the
"Fund"),  pursuant to which it acts as the distributor for the sale of shares of
Class D Insured Portfolio Series Common Stock, Class D National Portfolio Series
Common Stock and Class D Limited  Maturity  Portfolio  Series Common Stock,  par

    The term  "purchase"  refers to a single  purchase by an  individual,  or to
concurrent  purchases,  which  in  the  aggregate  are  at  least  equal  to the
prescribed  amounts,  by an individual,  his spouse and their children under the
age of 21 years  purchasing  Class D shares for his or their own  account and to
single purchases by a trustee or other fiduciary purchasing Class D 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  Investment  Company  Act of 1940,  as
amended,  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 Class D shares  of the Fund or Class D 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.

    The reduced sales  charges are  applicable  through a right of  accumulation
under which  eligible  investors are permitted to purchase Class D shares of the
Fund 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 Class A, Class B, Class C and  Class D shares  of the Fund
and of any  other  investment company  with an  initial  sales  charge for which
the  Distributor  acts as the distributor. For any  such  right of  accumulation
to be made  available, the Distributor must be provided at the time of purchase,
by the purchaser or you, with sufficient information to permit  confirmation  of
qualification,  and  acceptance  of  the  purchase  order  is  subject  to  such
confirmation.

    The reduced sales charges are applicable to purchases aggregating $25,000 or
more for the  Insured  and  National  Portfolios  and  $100,000  or more for the
Limited  Maturity  Portfolio of Class A shares or of Class D shares of any other
investment  company with an initial sales charge for which the Distributor  acts
as the distributor made through you within a thirteen-month period starting with
the first purchase pursuant to a Letter of Intention in the form provided in the
Prospectus. A purchase not originally made pursuant to a Letter of Intention may
be included under a subsequent  letter  executed within 90 days of such purchase
if the  Distributor  is informed  in writing of this  intent  within such 90-day
period.   If  the  intended  amount  of  shares  is  not  purchased  within  the
thirteen-month  period, an appropriate price adjustment will be made pursuant to
the terms of the Letter of Intention.

    You agree to advise us  promptly  at our  request as to amounts of any sales
made  by you  to the  public  qualifying  for  reduced  sales  charges.  Further
information  as  to  the  reduced  sales  charges   pursuant  to  the  right  of
accumulation  or a  Letter  of  Intention  is set  forth in the  Prospectus  and
Statement of Additional Information.

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

    5. As a selected  dealer,  you are  hereby  authorized  (i) to place  orders
directly  with the Fund for Class D shares of the Fund to be resold by us to you
subject to the applicable terms and conditions governing the placement of orders
by us set forth in Section 3 of the  Distribution  Agreement  and subject to the
compensation  provisions  of Section 3 hereof and (ii) to tender  Class D shares
directly to the Fund or its agent for redemption subject to the applicable terms
and conditions set forth in Section 4 of the Distribution Agreement.

    6. You shall not withhold  placing orders received from your customers so as
to profit  yourself as a result of such  withholding:  e.g.,  by a change in the
"net asset  value"  from that used in  determining  the  offering  price to your
customers.

    7. If any Class D shares sold to you under the terms of this  Agreement  are
repurchased by the Fund or by us for the account of the Fund or are tendered for
redemption  within seven business days after the date of the confirmation of the
original purchase by you, it is agreed that you shall forfeit your right to, and
refund to us, any discount received by you on such Class D shares.

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



                                      5

<PAGE>



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

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

    10. We reserve the right in our discretion, without notice, to suspend sales
or withdraw  the  offering of Class D shares  entirely or to certain  persons or
entities in a class or classes  specified by us. Each party hereto has the right
to cancel this agreement upon notice to the other party.

    11.  We  shall  have  full  authority  to take  such  action  as we may deem
advisable in respect of all matters  pertaining to the continuous  offering.  We
shall  be under no  liability  to you  except  for  lack of good  faith  and for
obligations expressly assumed by us herein.  Nothing contained in this paragraph
is intended to operate as, and the provisions of this paragraph shall not in any
way whatsoever  constitute,  a waiver by you of compliance with any provision of
the Securities Act of 1933, as amended,  or of the rules and  regulations of the
Securities and Exchange Commission issued thereunder.

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

    13. Upon  application to us, we will inform you as to the states in which we
believe the Class D shares  have been  qualified  for sale under,  or are exempt
from the requirements of, the respective  securities laws of such states, but we
assume no  responsibility  or obligation as to your right to sell Class D shares
in any jurisdiction. We will file with the Department of



                                      6

State in New York a Further State Notice with respect to the Class D shares,  if

specified by you below.

    15. Your first order placed  pursuant to this  Agreement for the purchase of

separate  investment  policies,  and  may in the  future  comprise  one or  more
additional portfolios; and
    

            WHEREAS,  MLFD is a  securities  firm  engaged  in the  business  of

     WHEREAS,  the Fund has entered into an Amended Class B Shares  Distribution

of each such Portfolio;
    

            WHEREAS,  the Fund  desires  to adopt  this  Distribution  Plan with
respect to Class B Limited Maturity Portfolio Series Common Stock; and

            WHEREAS,  the Directors of the Fund have  determined that there is a

            NOW,  THEREFORE,  the Fund hereby adopts, and the Distributor hereby
agrees to the terms of, this  Distribution  Plan (the "Plan") in accordance with
Rule  12b-l  under  the  Investment  Company  Act on  the  following  terms  and
conditions:

   
            1. The Fund shall pay MLFD an account maintenance fee under the Plan
at the end of each month with  respect to each  Portfolio of the Fund (i) at the
annual  rate of 0.50% of the  respective  average  daily net asset  value of the
Class B shares of the Insured and High Yield Portfolios,  and (ii) at the annual
rate of 0.20% of the average  daily net asset value of the Class B shares of the
Limited  Maturity  Portfolio to compensate MLFD and securities  firms with which
MLFD enters into related agreements  ("Sub-Agreements")  pursuant to Paragraph 3
hereof for account  maintenance  activities with respect to Class B shareholders
of the Fund. Only account maintenance  expenditures properly attributable to the
sale of Class B shares of a  Portfolio  will be used to justify  any fee paid by
the Fund with  respect to that  Portfolio  pursuant  to this Plan,  and,  to the
extent  that  such  expenditures   relate  to  more  than  one  Portfolio,   the
expenditures  will be  allocated  between the  affected  Portfolios  in a manner
deemed appropriate by the Board of Directors of the Fund.


            2. The Fund  shall pay MLFD a  distribution  fee under the Plan with
respect to each Portfolio of the Fund at the end of each month (i) at the annual
rate of 0.50% of the  respective  average  daily net asset  value of the Class B

of such Portfolios and payments related to the furnishing of services to Class B
shareholders by sales and marketing personnel.  Such expenditures may consist of
sales  commissions to financial  consultants  for selling Class B shares of such
Portfolios,  compensation,  sales incentives and payments to sales and marketing
personnel,  and the  payment of expenses  incurred in its sales and  promotional
activities, including advertising expenditures related

distributing promotional materials. The distribution fee may also be used to pay
the financing costs of carrying on the  unreimbursed  expenditures  described in
this Paragraph 2. Payment of the  distribution fee described in this Paragraph 2
shall be subject to any  limitations  set forth in applicable  regulation of the
National Association of Securities Dealers, Inc. Only distribution  expenditures
properly  attributable to the sale of Class B shares of a Portfolio will be used
to justify any fee paid by the Fund with respect to that  Portfolio  pursuant to

Portfolio, the expenditures will be allocated between the affected Portfolios in
a manner deemed appropriate by the Board of Directors of the Fund.

Fenner & Smith  Incorporated,  to provide  compensation to such Securities Firms
for activities and services of the type referred to in Paragraph 1 and 2 hereof.

            4. MLFD shall provide the Fund for review by the Board of Directors,
and the Directors shall review,  at least quarterly,  a written report complying
with the  requirements of Rule 12b-1  regarding the  disbursement of the account
maintenance fee and distribution fee during such period.

            5.  The  Prior  Plan  has  been  approved  by a vote  of at  least a
majority,  as defined in the Investment  Company Act, of the outstanding Class B
voting  securities of the Fund.  The Plan has not been  submitted to the Class B
shareholders  because the  amendments  do not  materially  increase  the rate of
payments by the Fund provided for in the Prior Plan.

            6. The Plan shall not take effect with respect to a Portfolio  until
it has been approved,  together with any related agreements with respect to that
Portfolio, by votes of a majority of both (a) the Board of Directors of the Fund

financial  interest in the operation of the Plan or any agreements related to it
(the "Rule 12b-1 Directors"), cast in person at a meeting or meetings called for
the purpose of voting on the Plan and such related agreements.

            7. The Plan shall continue in effect for so long as such continuance
is  specifically  approved at least annually in the manner provided for approval
of the Plan in Paragraph 6.

time by vote of a majority of the Rule 12b-l  Directors or by vote of a majority
of the outstanding Class B voting securities of that Portfolio.

            9. The Plan may not be amended to  increase  materially  the rate of
payments provided for herein with respect to a Portfolio of the Fund unless such
amendment  is  approved  by at least a  majority,  as defined in the  Investment
Company Act, of the outstanding  Class B voting securities of such Portfolio and
by the Board of Directors of the Fund in the manner  provided for in Paragraph 6
hereof,  and no material  amendment to the Plan shall be made unless approved in
the manner provided for approval and annual renewal in Paragraph 6 hereof.

            10. While the Plan is in effect,  the  selection  and  nomination of
Directors who are not interested  persons,  as defined in the Investment Company
Act, of the Fund shall be committed to the  discretion  of the Directors who are
not interested persons.

            11.  The Fund  shall  preserve  copies  of the Plan and any  related
agreements and all reports made pursuant to Paragraph 4 hereof,  for a period of
not less than six years  from the date of the Plan,  or the  agreements  or such
report, as the case may be, the first two years in an easily accessible place.

                    MERRILL LYNCH MUNICIPAL BOND FUND, INC.

                             PURSUANT TO RULE 12b-1

      DISTRIBUTION  PLAN made as of the 21st day of October 1994, by and between
MERRILL LYNCH MUNICIPAL BOND FUND,  INC., a Maryland  corporation  (the "Fund"),
and Merrill Lynch Funds Distributor, Inc., a Delaware corporation ("MLFD").

                             W I T N E S S E T H :

      WHEREAS, the Fund is engaged in business as an open-end investment company
registered under the Investment Company Act of 1940, as amended (the "Investment
Company Act"); and

      WHEREAS, the Fund is comprised of three separate  portfolios,  namely, the
Insured  Portfolio,  the National  Portfolio and the Limited Maturity  Portfolio
(the "Portfolios"),  each of which pursues its own investment  objective through
separate  investment  policies,  and  may in the  future  comprise  one or  more
additional portfolios; and

      WHEREAS,  MLFD is a  securities  firm  engaged in the  business of selling
shares of investment  companies  either  directly to purchasers or through other
securities dealers; and

      WHEREAS,  the Fund  proposes  to enter into a Class D Shares  Distribution
Agreement  with  MLFD,  pursuant  to  which  MLFD  will  act  as  the  exclusive
distributor  and  representative  of the Fund in the offer and sale of shares of
the  Class D  Insured  Portfolio  Series  Common  Stock,  the  Class D  National
Portfolio  Series Common Stock and the Class D Limited Maturity Portfolio Series
Common Stock, par value $0.10 per share (collectively, the "Class D shares"), of
the Fund to the public; and

      WHEREAS,  the Fund  desires to adopt this Class D  Distribution  Plan (the
"Plan")  pursuant to Rule 12b-1 under the  Investment  Company Act,  pursuant to
which the Fund will pay an account  maintenance  fee to MLFD with respect to the
Class D shares of each Portfolio; and

      WHEREAS,  the  Directors  of the  Fund  have  determined  that  there is a
reasonable  likelihood  that  adoption  of the Plan  will  benefit  the Fund and
shareholders of each Portfolio.

      NOW,  THEREFORE,  the Fund hereby  adopts,  and MLFD hereby  agrees to the
terms of, the Plan in accordance  with Rule 12b-1 under the  Investment  Company
Act on the following terms and conditions:




<PAGE>




      1. The Fund  shall pay MLFD an account  maintenance  fee under the Plan at
the end of each month  with  respect  to each  Portfolio  of the Fund (i) at the
annual  rate of 0.25% of  average  daily net assets of the Class D shares of the
Insured  and  National  Portfolios  and (ii) at the annual  rate of 0.10% of the
average daily net assets of the Class D  shares  of the  Limited  Maturity
Portfolio,  to  compensate  MLFD and securities  firms with which MLFD enters
into  related  agreements  pursuant to Paragraph  3  hereof   ("Sub-Agreements")
for  providing  account  maintenance activities with respect to Class D
shareholders  of the Portfolio.  Expenditures under the Plan may consist of
payments to financial  consultants for maintaining accounts in  connection
with Class D shares of each  Portfolio  of the Fund and payment  of  expenses
incurred  in  connection  with such  account  maintenance activities  including
the costs of making  services  available to  shareholders including  assistance
in  connection  with  inquiries  related  to  shareholder accounts. Only account
maintenance expenditures  properly attributable to the Class D shares of a
Portfolio  will be used to justify any fee paid by the Fund with respect to that
Portfolio  pursuant to this Plan,  and, to the extent that such  expenditures
relate to more than one Portfolio,  the expenditures will be allocated between
the affected  Portfolios in a manner deemed appropriate by the Board of
Directors of the Fund.

      2. The Fund  hereby  authorizes  MLFD to enter  into  Sub-Agreements  with
certain securities firms ("Securities Firms"),  including Merrill Lynch, Pierce,
Fenner & Smith  Incorporated,  to provide  compensation to such Securities Firms
for  activities  and  services  of the type  referred to in  Paragraphs  1 and 2
hereof.  MLFD may reallocate all or a portion of its account  maintenance fee
to  such   Securities   Firms   as   compensation   for  the
above-mentioned  activities and services.  Such Sub-Agreement shall provide that
the Securities  Firms shall provide MLFD with such  information as is reasonably
necessary to permit MLFD to comply with the reporting  requirements set forth in
Paragraph 3 hereof.

      3. MLFD shall provide the Fund for review by the Board of  Directors,  and
the Directors shall review, at least quarterly,  a written report complying with
the  requirements  of Rule  12b-1  regarding  the  disbursement  of the  account
maintenance fee during such period.




                                       2

      4. This Plan shall not take effect with respect to a Portfolio of the Fund
until it has been  approved by a vote of at least a majority,  as defined in the
Investment  Company Act, of the  outstanding  Class D voting  securities of such
Portfolio.

      5. This Plan shall not take effect  until it has been  approved,  together
with any  related  agreements,  by votes of a majority  of both (a) the Board of
Directors  of the  Fund  and  (b)  those  Directors  of the  Fund  who  are  not
"interested  persons" of the Fund, as defined in the Investment Company Act, and
have no direct or indirect  financial  interest in the operation of this Plan or
any agreements related to it (the "Rule 12b-1  Directors"),  cast in person at a
meeting  or  meetings  called  for the  purpose  of  voting on the Plan and such
related agreements.

      6. The Plan shall  continue in effect for so long as such  continuance  is
specifically  approved at least annually in the manner  provided for approval of
the Plan in Paragraph 5.

      7. The Plan may be  terminated  at any time with respect to a Portfolio of
the Fund by vote of a  majority  of the Rule  12b-1  Directors,  or by vote of a
majority of the outstanding Class D voting securities of that Portfolio.

      8. The Plan may not be amended to increase materially the rate of payments
provided  for  herein  with  respect  to a  Portfolio  of the Fund  unless  such
amendment  is  approved  by at least a  majority,  as defined in the  Investment
Company Act, of the outstanding Class D voting securities of such Portfolio, and
by the Board of Directors of the Fund in the manner  provided for in Paragraph 6
hereof,  and no material  amendment to the Plan shall be made unless approved in
the manner provided for approval and annual renewal in Paragraph 5 hereof.

      9. While the Plan is in effect,  the selection and nomination of Directors
who are not interested persons, as defined in the Investment Company Act, of the
Fund  shall  be  committed  to the  discretion  of the  Directors  who  are  not
interested persons.

      10. The Fund shall preserve copies of the Plan and any related  agreements
and all reports made  pursuant to  Paragraph 4 hereof,  for a period of not less
than six years from the date of the Plan, or the  agreements or such report,  as
the case may be, the first two years in an easily accessible place.
