OCTOBER 21, 1994
    

   
                   MERRILL LYNCH MICHIGAN MUNICIPAL BOND FUND
                MERRILL LYNCH MULTI-STATE MUNICIPAL SERIES TRUST
   P.O. BOX 9011, PRINCETON, NEW JERSEY 08543-9011--PHONE NO. (609) 282-2800
    
                              -------------------

   
    Merrill  Lynch Michigan  Municipal Bond Fund  (the "Fund") is  a mutual fund
seeking to  provide shareholders  with as  high a  level of  income exempt  from
Federal  and  Michigan income  taxes as  is  consistent with  prudent investment
management. The Fund invests primarily  in a non-diversified portfolio of  long-
term,  investment grade  obligations, the interest  on which, in  the opinion of
bond counsel to  the issuer, is  exempt from Federal  and Michigan income  taxes
("Michigan Municipal Bonds"). Dividends paid by the Fund are exempt from Federal
and  Michigan  income taxes  to the  extent  they are  derived from  interest on
Michigan Municipal Bonds. The Fund  may invest in certain tax-exempt  securities
classified as "private activity bonds" that may subject certain investors in the
Fund  to an alternative  minimum tax. At times,  the Fund may  seek to hedge its
portfolio through the use of futures  transactions and options. There can be  no
assurance that the investment objective of the Fund will be realized.
    

   
    Pursuant  to the  Merrill Lynch Select  Pricing-SM- System,  the Fund offers
four classes of  shares, each  with a  different combination  of sales  charges,
ongoing  fees and  other features. The  Merrill Lynch  Select Pricing-SM- System
permits an investor to choose the method of purchasing shares that the  investor
believes is most beneficial given the amount of the purchase, the length of time
the  investor expects to  hold the shares and  other relevant circumstances. See
"Merrill Lynch Select Pricing-SM- System" on page 3.
    
   
    Shares may be purchased directly from Merrill Lynch Funds Distributor,  Inc.
(the  "Distributor"),  P.O. Box  9011, Princeton,  New Jersey  08543-9011 [(609)
282-2800], or from securities dealers which have entered into dealer  agreements
with   the  Distributor,  including  Merrill   Lynch,  Pierce,  Fenner  &  Smith
Incorporated ("Merrill Lynch"). The minimum  initial purchase is $1,000 and  the
minimum  subsequent purchase  is $50. Merrill  Lynch may charge  its customers a
processing fee  (presently  $4.85)  for confirming  purchases  and  repurchases.
Purchases  and redemptions  directly through the  Fund's Transfer  Agent are not
subject to  the processing  fee. See  "Purchase of  Shares" and  "Redemption  of
Shares".

Trust (the "Trust") at the above  telephone number or address. The Statement  of
Additional Information is hereby incorporated by reference into this Prospectus.

company organized as a Massachusetts business trust.

(e)  Class  A and Class D shares are  not subject to a contingent deferred sales
     charge ("CDSC"), except that purchases of $1,000,000 or more which are  not
     subject  to an  initial sales charge  may instead  be subject to  a CDSC if
     redeemed within the first year of purchase.
(f)  Information for Class A and  Class B shares is  stated for the fiscal  year

An investor would pay the following expenses on a $1,000
  investment including the maximum $40 initial sales charge

</TABLE>
    

   
    As  of July 31, 1994,  Fund Asset Management, L.P.  ("FAM" or the "Manager")
was voluntarily  waiving  a  portion  of  its  management  fee  and  voluntarily
reimbursing the Fund for a portion of other expenses (excluding 12b-1 fees). The
fee table has been restated to assume the absence of any waiver or reimbursement
because  the Manager  may discontinue  or reduce  such waiver  and assumption of
expenses at any time without notice. During the fiscal year ended July 31, 1994,
the Manager waived management  fees and reimbursed  expenses totaling 0.69%  for
Class A shares and 0.70% for Class B shares after which the Fund's total expense
ratio  was 0.31% for  Class A shares and  0.81% for Class B  shares. Class C and
Class D shares were not offered during that year.
    

   
    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 RATE OF RETURN,
AND ACTUAL EXPENSES  OR ANNUAL RATE  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  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  Manager, has  voluntarily agreed to  assume a portion  of the operating
expenses of the Fund. The Manager  may discontinue or reduce such assumption  of
expenses at any time without notice.
    

   
                    MERRILL LYNCH SELECT PRICING-SM- SYSTEM
    

   
    The  Fund  offers four  classes  of shares  under  the Merrill  Lynch Select
Pricing-SM- System. The shares of each class  may be purchased at a price  equal
to  the next determined net  asset value per share  subject to the sales charges
and ongoing fee arrangements described below. Shares of Class A and Class D  are
sold to
    

                                       3
<PAGE>
   
investors  choosing the initial sales charge alternatives, and shares of Class B
and  Class  C  are  sold  to  investors  choosing  the  deferred  sales   charge
alternatives.  The Merrill Lynch Select  Pricing System is used  by more than 50
mutual funds advised  by Merrill Lynch  Asset Management, L.P.  ("MLAM") or  its
affiliate,  FAM.  Funds  advised  by  MLAM or  FAM  are  referred  to  herein as
"MLAM-advised mutual funds".
    

   
    Each Class A, Class B,  Class C or Class D  share of the Fund represents  an
identical  interest in  the investment  portfolio of the  Fund and  has the same
rights, except that Class B, Class C and Class D shares bear the expenses of the
ongoing account  maintenance  fees and  Class  B and  Class  C shares  bear  the
expenses  of  the  ongoing  distribution  fees  and  the  additional incremental
transfer agency costs resulting from the deferred sales charge arrangements. The
deferred sales charges and account maintenance fees that are imposed on Class  B
and  Class C shares, as well as the account maintenance fees that are imposed on
the Class  D shares,  will be  imposed directly  against those  classes and  not
against  all assets of the  Fund and, accordingly, such  charges will not affect
the net asset value of any other class or have any impact on investors  choosing
another sales charge option. Dividends paid by the Fund for each class of shares
will  be calculated in the same manner at  the same time and will differ only to
the extent that account  maintenance and distribution  fees and any  incremental
transfer  agency costs relating  to a particular class  are borne exclusively by
that class.  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 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 the "Purchase of 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 Alternative -- Class A and Class D Shares -- Eligible Class  A
     Investors".
(3)  Reduced  for  purchases of  $25,000  or more.  Class  A and  Class  D share
     purchases of $1,000,000  or more  may not be  subject to  an initial  sales
     charge  but instead may be  subject to a CDSC  if redeemed within one year.
     See "Class A" and "Class D" below.
(4)  The  conversion  period  for  dividend  reinvestment  shares  and   certain
     retirement  plans  is  modified.  Also, Class  B  shares  of  certain other
     MLAM-advised mutual funds into  which exchanges may be  made have an  eight
     year  conversion period. If  Class B shares  of the Fund  are exchanged for
     Class B shares of another  MLAM-advised mutual fund, the conversion  period
     applicable  to the Class B shares acquired  in the exchange will apply, and
     the holding period for the shares exchanged will be tacked onto the holding
     period for the shares acquired.

CLASS A:   Class A shares incur an initial sales  charge when they are purchased and bear  no
           ongoing  distribution or account maintenance fees. Class A shares are offered to a
           limited group of investors and also will be issued upon reinvestment of  dividends
           on  outstanding Class A shares.  Investors that currently own  Class A shares in a
           shareholder account are  entitled to purchase  additional Class A  shares in  that
           account. In addition, Class A shares will be offered to directors and employees of
           Merrill  Lynch & 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 to members of the Boards of MLAM-advised mutual funds.  The
           maximum  initial sales charge is 4.00%, which  is reduced for purchases of $25,000
           and over. Purchases of $1,000,000 or more  may not be subject to an initial  sales
           charge but if the initial sales charge is waived, such purchases may be subject to
           a  CDSC 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
           investor's holdings of all classes of all MLAM-advised mutual funds. See "Purchase
           of Shares -- Initial Sales Charge Alternatives -- Class A and Class D Shares".

CLASS B:   Class  B shares do not incur a sales  charge when they are purchased, but they are
           subject to an ongoing account maintenance fee of 0.25% and an ongoing distribution
           fee of  0.25% and  a CDSC  if they  are redeemed  within four  years of  purchase.
           Approximately  ten years after issuance, Class B shares will convert automatically
           into Class D shares of the Fund, which are subject to a lower account  maintenance
           fee of 0.10% and no distribution fee; Class B shares of certain other MLAM-advised
           mutual  funds  into  which exchanges  may  be  made convert  into  Class  D shares
           automatically after approximately eight years. If  Class B shares of the Fund  are
           exchanged  for Class B shares of  another MLAM-advised mutual fund, the conversion
           period applicable to the Class  B shares acquired in  the exchange will apply,  as
           will the Class D account maintenance fee of the acquired fund upon the conversion,
           and  the holding period for  the shares exchanged will  be tacked onto the holding
           period for the shares acquired. Automatic conversion of Class B shares into  Class
           D  shares will occur at least once a month  on the basis of the relative net asset
           values of  the shares  of the  two classes  on the  conversion date,  without  the
           imposition of any sales load, fee or other charge. Conversion of Class B shares to
           Class  D shares will  not be deemed a  purchase or sale of  the shares for Federal
           income tax purposes. Shares purchased through reinvestment of dividends on Class B
           shares also will convert  automatically to Class D  shares. The conversion  period
           for  dividend reinvestment shares and for  certain retirement plans is modified as
           described under "Purchase of Shares -- Deferred Sales Charge Alternatives -- Class
           B and Class C Shares -- Conversion of Class B Shares to Class D Shares".
CLASS C:   Class C shares do not incur a sales  charge when they are purchased, but they  are
           subject to an ongoing account maintenance fee of 0.25% of average daily net assets
           and  an ongoing distribution  fee of 0.35%. 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),
           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
           Trust's Board of Trustees and regulatory limitations.
CLASS D:   Class  D shares  incur an  initial sales  charge when  they are  purchased and are
           subject to an  ongoing account  maintenance fee of  0.10% of  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  may not  be subject  to  an
           initial  sales charge, but  if the initial  sales charge is  waived such purchases
           will be subject to a CDSC of 1.0% if the shares are redeemed within one year after
           purchase. The schedule  of initial sales  charges and reductions  for the Class  D
           shares is the same as the schedule for Class A shares. Class D shares also will be
           issued  upon conversion of Class B shares  as described above under "Class B". See
           "Purchase of Shares -- Initial  Sales Charge Alternatives --  Class A and Class  D
           Shares".
</TABLE>
    

   
    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
    

                                       6
<PAGE>
   
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 shares holdings, will count toward a right  of
accumulation which may qualify the investor for reduced initial sales charges on
new initial sales charge purchases. In addition, the ongoing Class B and Class C
account  maintenance and distribution fees will cause Class B and Class C shares
to have higher expense ratios, pay lower dividends and have lower total  returns
than  the initial sales  charge shares. The ongoing  Class D account maintenance
fees will  cause Class  D  shares to  have a  higher  expense ratio,  pay  lower
dividends and have a lower total return than Class A shares.
    

   
    DEFERRED  SALES CHARGE ALTERNATIVES.   Because no  initial sales charges are
deducted at the time of purchase, Class B and Class C shares provide the benefit
of putting all of the investor's dollars to work from the time the investment is
made. The deferred sales  charge alternatives may  be particularly appealing  to
investors  who do  not qualify  for a reduction  in initial  sales charges. Both
Class B and Class C shares are  subject to ongoing account maintenance fees  and
distribution  fees; however,  the ongoing  account maintenance  and distribution
fees potentially may  be offset  to the  extent any  return is  realized on  the
additional  funds initially invested in Class B  or Class C shares. In addition,
Class B  shares will  be converted  into  Class D  shares of  the Fund  after  a
conversion  period of approximately ten years,  and thereafter investors will be
subject to lower ongoing fees.
    

   
    Certain investors may elect to purchase Class B shares if they determine  it
to be most advantageous to have all their funds invested initially and intend to
hold  their shares for an  extended period of time.  Investors in Class B shares
should take into account whether they  intend to redeem their shares within  the
CDSC period and, if not, whether they intend to remain invested until the end of
the  conversion period  and thereby take  advantage of the  reduction in ongoing
fees resulting  from  the  conversion  into Class  D  shares.  Other  investors,
however,  may elect  to purchase  Class C  shares if  they determine  that it is
advantageous to have all their assets invested initially and they are  uncertain
as to the length of time they intend to hold their assets in MLAM-advised mutual
funds.  Although Class C shareholders are subject  to a shorter CDSC period at a
lower rate, they are subject to higher  distribution fees and forgo the Class  B
conversion  feature, making their investment  subject to account maintenance and
distribution fees for  an indefinite  period of  time. In  addition, while  both
Class  B  and  Class C  distribution  fees  are subject  to  the  limitations on
asset-based sales charges imposed by the NASD, the Class B distribution fees are
further limited  under a  voluntary  waiver of  asset-based sales  charges.  See
"Purchase of Shares -- Limitations on the Payment of Deferred Sales Charges".

                       INVESTMENT OBJECTIVE AND POLICIES

    The investment objective of the Fund is to provide shareholders with as high
a level of income exempt from Federal and Michigan income taxes as is consistent
with  prudent investment  management. The  Fund seeks  to achieve  its objective
while providing  investors with  the opportunity  to invest  in a  portfolio  of
securities  consisting primarily of long-term obligations issued by or on behalf
of  the   State  of   Michigan,  its   political  subdivisions,   agencies   and
instrumentalities  and obligations of other  qualifying issuers, such as issuers
located in Puerto Rico, the Virgin Islands and Guam, which pay interest  exempt,
in  the opinion of bond counsel to  the issuer, from Federal and Michigan income
taxes. Obligations exempt from  Federal income taxes are  referred to herein  as
"Municipal  Bonds" and obligations exempt from  both Federal and Michigan income
taxes are referred to as "Michigan Municipal Bonds." Unless otherwise indicated,
references to  Municipal Bonds  shall be  deemed to  include Michigan  Municipal
Bonds.  The Fund at  all times, except during  temporary defensive periods, will
maintain at least 65% of its total assets invested in Michigan Municipal  Bonds.
The  investment objective of the Fund as set forth in the first sentence of this
paragraph is a  fundamental policy and  may not be  changed without  shareholder
approval.  At times, the Fund may seek to hedge its portfolio through the use of
futures transactions to reduce volatility in the net asset value of Fund shares.

   
    Municipal Bonds may include  several types of bonds.  The risks and  special
considerations involved in investment in Municipal Bonds, vary with the types of
instruments  being acquired. Investments in Non-Municipal Tax-Exempt Securities,
as defined  herein,  may present  similar  risks, depending  on  the  particular
product.  Certain instruments in which the  Fund may invest may be characterized
as derivative instruments. See "Description  of Municipal Bonds" and  "Financial
Futures  Transactions and  Options". The Fund  also may invest  in variable rate
demand obligations and participate therein, described below, and short term tax-
exempt municipal obligations  such as  tax anticipation notes.  The interest  on
Municipal  Bonds may bear a  fixed rate or be payable  at a variable or floating
rate. At least 80% of the Municipal  Bonds purchased by the Fund primarily  will
be  what are  commonly referred to  as "investment grade"  securities, which are
obligations rated  at the  time  of purchase  within  the four  highest  quality
ratings  as  determined by  either Moody's  Investors Service,  Inc. ("Moody's")
(currently Aaa,  Aa, A  and Baa),  Standard &  Poor's Corporation  ("Standard  &
Poor's")  (currently  AAA,  AA, A  and  BBB)  or Fitch  Investors  Service, Inc.
("Fitch") (currently AAA, AA, A and  BBB). If Municipal Bonds are unrated,  such
securities  will  possess creditworthiness  comparable,  in the  opinion  of the
Manager, to obligations in which the  Fund may invest. Municipal Bonds rated  in
the  fourth highest rating  category, while considered  "investment grade", have
certain speculative  characteristics and  are more  likely to  be downgraded  to
non-investment  grade  than obligations  rated in  one of  the top  three rating
categories. See Appendix II -- "Ratings of Municipal Bonds" in the Statement  of
Additional   Information  for   more  information  regarding   ratings  of  debt
securities. An issue  of rated  Municipal Bonds  may cease  to be  rated or  its
rating may be reduced below "investment grade" subsequent to its purchase by the
Fund.  If an obligation  is downgraded below investment  grade, the Manager will
consider factors  such  as  price, credit  risk,  market  conditions,  financial
condition  of the issuer and interest rates  to determine whether to continue to
hold the obligation in the Fund's portfolio.
    

   
    The Fund may invest up  to 20% of its total  assets in Municipal Bonds  that
are  rated below Baa  by Moody's or below  BBB by Standard &  Poor's or Fitch or
which, in the Manager's judgment,  possess similar credit characteristics.  Such
securities,   sometimes  referred  to  as  "high-yield"  or  "junk"  bonds,  are
predominantly speculative with respect to the capacity to pay interest and repay
principal in accordance with the terms  of the security and generally involve  a
greater    volatility   of    price   than    securities   in    higher   rating
    

                                       9
<PAGE>
categories. The  market  prices  of high-yielding,  lower-rated  securities  may
fluctuate  more than  higher-rated securities  and may  decline significantly in
periods of  general economic  difficulty,  which may  follow periods  of  rising
interest  rates.  In  purchasing such  securities,  the  Fund will  rely  on the
Manager's judgment, analysis and  experience in evaluating the  creditworthiness
of  the issuer  of such  securities. The  Manager will  take into consideration,
among other  things,  the  issuer's  financial  resources,  its  sensitivity  to
economic  conditions  and  trends, its  operating  history, the  quality  of its
management and regulatory  matters. See "Investment  Objective and Policies"  in
the  Statement of Additional  Information for a more  detailed discussion of the
pertinent risk factors involved in investing in "high yield" or "junk" bonds and
Appendix II  -- "Ratings  of Municipal  Bonds" in  the Statement  of  Additional
Information for additional information regarding ratings of debt securities. The
Fund  does not intend to  purchase debt securities that  are in default or which
the Manager believes will be in default.

   
    Certain Municipal Bonds may be entitled to the benefits of letters of credit
or similar  credit  enhancements  issued  by  financial  institutions.  In  such
instances,  the Trustees and the Manager will take into account in assessing the
quality of such bonds not only the creditworthiness of the issuer of such  bonds
but also the creditworthiness of the financial institution.
    
    The  Fund's investments  may also  include variable  rate demand obligations
("VRDOs") and  VRDOs  in the  form  of participation  interests  ("Participating
VRDOs") in variable rate tax-exempt obligations held by a financial institution.
The VRDOs in which the Fund will invest are tax-exempt obligations which contain
a  floating or  variable interest rate  adjustment formula  and an unconditional
right of demand  on the part  of the holder  thereof to receive  payment of  the
unpaid  principal balance plus accrued interest on  a short notice period not to
exceed seven  days.  Participating  VRDOs  provide the  Fund  with  a  specified
undivided  interest (up to 100%)  of the underlying obligation  and the right to
demand payment of  the unpaid  principal balance  plus accrued  interest on  the
Participating  VRDOs from  the financial  institution on  a specified  number of
days' notice, not to exceed seven days. There is, however, the possibility  that
because of a default or insolvency, the demand feature of VRDOs or Participating
VRDOs may not be honored. The Fund has been advised by its counsel that the Fund
should  be  entitled to  treat  the income  received  on Participating  VRDOs as
interest from tax-exempt obligations.

    VRDOs that contain an  unconditional right of demand  to receive payment  of
the  unpaid principal balance plus accrued interest on a notice period exceeding
seven days may be deemed to be illiquid securities. A VRDO with a demand  notice
period  exceeding seven days will therefore be subject to the Fund's restriction
on illiquid investments unless, in the  judgement of the Trustees, such VRDO  is
liquid.  The Trustees may adopt guidelines and delegate to the Manager the daily
function of determining and  monitoring liquidity of  such VRDOs. The  Trustees,
however, will retain sufficient oversight and be ultimately responsible for such
determinations.

    The  Fund ordinarily does not intend to realize investment income not exempt
from Federal and  Michigan income taxes.  However, to the  extent that  suitable
Michigan  Municipal Bonds are not available for investment by the Fund, the Fund
may purchase  Municipal  Bonds  issued  by  other  states,  their  agencies  and
instrumentalities,  the interest  income on which  is exempt, in  the opinion of
bond counsel, from Federal, but not Michigan, taxation. The Fund also may invest
in securities not issued by or on behalf of a state or territory or by an agency
or instrumentality thereof, if the Fund nevertheless believes such securities to
be exempt from Federal income taxation ("Non-Municipal Tax-Exempt  Securities").
Non-Municipal  Tax-Exempt  Securities  may include  securities  issued  by other
investment companies that invest in municipal

                                       10
<PAGE>
bonds, to the extent  such investments are permitted  by the Investment  Company
Act  of  1940,  as  amended (the  "1940  Act").  Other  Non-Municipal Tax-Exempt
Securities could  include trust  certificates  or other  instruments  evidencing
interests in one or more long-term municipal securities.

    Under   normal   circumstances,  except   when  acceptable   securities  are
unavailable as determined by the Manager, the  Fund will invest at least 65%  of
its total assets in Michigan Municipal Bonds. For temporary defensive periods or
to provide liquidity, the Fund has the authority to invest as much as 35% of its
total  assets in tax-exempt or taxable  money market obligations with a maturity
of one year  or less (such  short-term obligations being  referred to herein  as
"Temporary  Investments"), except  that taxable Temporary  Investments shall not
exceed 20%  of the  Fund's  net assets.  The  Temporary Investments,  VRDOs  and
Participating  VRDOs in which the Fund may  invest also will be in the following
rating categories at the time of purchase; MIG-1/VMIG-1 through MIG-4/VMIG-4 for
notes and VRDOs and Prime-1 through Prime-3 for commercial paper (as  determined
by Moody's), SP-1 or SP-2 for notes and A-1 through A-3 for VRDOs and commercial
paper  (as determined by Standard & Poor's), or F-1 through F-3 for notes, VRDOs
and commercial paper  (as determined  by Fitch)  or, if  unrated, of  comparable
quality  in the opinion of the Manager. The Fund at all times will have at least
80% of its net  assets invested in  securities the interest  on which is  exempt
from   Federal  taxation.  However,  interest   received  on  certain  otherwise
tax-exempt securities  which  are classified  as  "private activity  bonds"  (in
general,  bonds that  benefit non-governmental  entities), may  be subject  to a
Federal alternative  minimum  tax.  The  percentage of  the  Fund's  net  assets
invested   in  "private  activity   bonds"  will  vary   during  the  year.  See
"Distributions and Taxes". In  addition, the Fund reserves  the right to  invest
temporarily  a  greater  portion  of its  assets  in  Temporary  Investments for
defensive purposes,  when, in  the judgment  of the  Manager, market  conditions
warrant.  The investment objective  of the Fund  is a fundamental  policy of the
Fund which may be not  changed without a vote of  a majority of the  outstanding
shares  of the Fund. The Fund's hedging  strategies, which are described in more
detail under "Financial Futures Transactions  and Options", are not  fundamental
policies  and may be modified by the  Trustees of the Trust without the approval
of the Fund's shareholders.

POTENTIAL BENEFITS

   
    Investment in shares of  the Fund offers several  benefits. The Fund  offers
investors  the opportunity  to receive income  exempt from  Federal and Michigan
income taxes  by  investing in  a  professionally managed  portfolio  consisting
primarily  of  long-term  Michigan  Municipal  Bonds.  The  Fund  also  provides
liquidity because of its  redemption features and relieves  the investor of  the
burdensome administrative details involved in managing a portfolio of tax-exempt
securities.  The benefits of investing in the Fund are at least partially offset
by the  expenses involved  in  operating an  investment company.  Such  expenses
primarily  consist of the management fee and  operational costs, and in the case
of certain classes of shares, account maintenance and distribution fees.
    
SPECIAL AND RISK CONSIDERATIONS RELATING TO MICHIGAN MUNICIPAL BONDS

    The Fund ordinarily will invest at least 65% of its total assets in Michigan
Municipal Bonds,  and therefore  it  is more  susceptible to  factors  adversely
affecting  issuers of Michigan Municipal Bonds  than is a tax-exempt mutual fund
that is not concentrated in issuers of Michigan Municipal Bonds to this  degree.
In  recent years, the  State of Michigan  has reported its  financial results in
accordance with generally accepted accounting  principles. For each of the  five
fiscal  years ending with  the fiscal year  ended September 30,  1989, the State
reported positive  year-end fund  balances  and positive  cash balances  in  the
combined  General Fund/School Aid Fund. For the fiscal years ended September 30,
1990 and 1991,  the State reported  negative year-end General  Fund balances  of
$310.4  million  and $169.4  million, respectively,  but  ended the  1992 fiscal

                                       11
<PAGE>
   
year with its General Fund in balance.  A positive cash balance in the  combined
General  Fund/School Aid Fund was recorded at September 30, 1990. In each of the
last three fiscal years,  the State has undertaken  mid-year actions to  address
projected year-end budget deficits, including expenditure cuts and deferrals and
one  time expenditures  or revenue recognition  adjustments. In  the fiscal year
ended September  30,  1993, the  State  took  mid-year actions  to  eliminate  a
projected  year-end General Fund  deficit of $370 million.  Since 1991 the State
has experienced deteriorating cash  balances which have necessitated  short-term
borrowings  and  the  deferral of  certain  scheduled cash  payments.  The State
borrowed $700 million for cash  flow purposes in the  1992 fiscal year and  $900
million  in the  1993 fiscal  year. The  State has  a Budget  Stabilization Fund
which, after a transfer of $230 million to the General Fund for the 1991  fiscal
year,  had an  accrued balance of  $182 million as  of September 30,  1991 and a
balance of $20.1 million as of September 30, 1992. In May, 1986, Moody's  raised
the  State's general obligation bond rating to  A1. In October, 1989, Standard &
Poor's raised its  rating on  the State's general  obligation bonds  to AA.  The
State's  economy could continue to be affected  by changes in the auto industry,
notably consolidations and plant  closings resulting from competitive  pressures
and  overcapacity.  See  Appendix  I,  "Economic  and  Financial  Conditions  in
Michigan" in the Statement of Additional Information.
    

DESCRIPTION OF MUNICIPAL BONDS

    Municipal Bonds include debt obligations issued to obtain funds for  various
public  purposes, including construction and equipping of a wide range of public
facilities (including water, sewer, gas, electricity, solid waste, health  care,
transportation,  education  and  housing facilities),  refunding  of outstanding
obligations and  obtaining funds  for general  operating expenses  and loans  to
other  public  institutions  and  facilities.  In  addition,  certain  types  of
industrial development bonds are issued by or on behalf of public authorities to
finance various  privately  operated  facilities,  including  pollution  control
facilities  or other  specialized facilities.  For purposes  of this Prospectus,
such obligations are Municipal Bonds if the interest paid thereon is exempt from
Federal income tax, and, as Michigan Municipal Bonds if the interest thereon  is
exempt  from Federal  income tax and  exempt from Michigan  personal income tax,
even though such bonds may be "private activity bonds" as discussed below.

   
    The  two  principal   classifications  of  Municipal   Bonds  are   "general
obligation"  bonds and "revenue" bonds which latter category includes industrial
development bonds ("IDBs") or private  activity bonds. General obligation  bonds
are secured by the issuer's pledge of its faith, credit and taxing power for the
payment  of principal and interest. The  taxing power of any governmental entity
may be limited, however,  by provisions of state  constitutions or laws, and  an
entity's  creditworthiness  will  depend on  many  factors,  including potential
erosion of the tax base due to population declines, natural disasters,  declines
in  the state's industrial base or inability to attract new industries, economic
limits on the  ability to tax  without eroding the  tax base, state  legislative
proposals  or voter initiatives to limit ad  valorem real property taxes and the
extent to which the  entity relies on  Federal or state  aid, access to  capital
markets  or other factors beyond the state or entity's control. Accordingly, the
capacity of the issuer of a general obligation bond as to the timely payment  of
interest  and the repayment  of principal when  due is affected  by the issuer's
maintenance of its tax base.
    

   
    Revenue bonds are payable only from  the revenues derived from a  particular
facility  or  class of  facilities or,  in some  cases, from  the proceeds  of a
special excise tax or other specific revenue source such as from the user of the
facility being financed;  accordingly, the  timely payment of  interest and  the
repayment  of principal in accordance  with the terms of  the revenue or special
obligation bond is a function of the economic viability of such facility or such
revenue source. The  Fund also  may invest  in "moral  obligation" bonds,  which
    

                                       12
<PAGE>
   
normally are 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  of
municipality  in question. The Fund  will not invest more  than 10% of its total
assets (taken at  market value  at the time  of each  investment) in  industrial
revenue  bonds where the  entity supplying the  revenues from which  the user is
paid, including  predecessors,  has  a  record  of  less  than  three  years  of
continuous  business operations.  Investments involving entities  with less than
three years of continuous  business operations may  pose somewhat greater  risks
due  to  the lack  of a  substantial  operating history  for such  entities. The
Manager believes,  however,  that the  potential  benefits of  such  investments
outweigh  the potential risks particularly given  the Fund's limitations on such
investments.
    
   
    The Fund may purchase IDBs. IDBs are tax-exempt securities issued by states,
municipalities or public authorities  and are issued  to provide funds,  usually
through a loan or lease arrangement, to a private corporation for the purpose of
financing  construction  or  improvement  of  a  facility  to  be  used  by  the
corporation. Such  bonds are  secured primarily  by revenues  derived from  loan
repayments  or lease payments due  from the corporation which  may or may not be
guaranteed by  a  parent company  or  otherwise secured.  In  view of  this,  an
investor should be aware that repayment of such bonds depends on the revenues of
a  private corporation  and be aware  of the  risks that such  an investment may
entail. Continued ability of a  corporation to generate sufficient revenues  for
the  payment of principal  and interest on  such bonds will  be affected by many
factors including the size of the corporation, capital structure, demand for its
products or  services, competition,  general economic  conditions,  governmental
regulation and the corporation's dependence on revenues for the operation of the
particular  facility being financed.  The Fund may  invest more than  25% of its
total assets in IDBs or private activity bonds.
    

   
    The Fund may 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 maturity of certain Municipal Bonds also may be based on the
value  of an index. To  the extent the Fund invests  in these types of Municipal
Bonds, the Fund's return  on such Municipal  Bonds will be  subject to the  risk
with  respect to the value of the particular 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  tax  exempt  securities  increase or  decrease  in  response  to such
changes. As a  result, the market  values of such  securities will generally  be
more  volatile than  the market values  of fixed-rate tax  exempt securities. To
seek to limit the volatility of these securities, the Fund may purchase  inverse
floating  obligations with shorter term  maturities or which contain limitations
on the extent to  which the interest  rate may vary.  The Manager 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 15% of the Fund's net assets.

    Also  included  within   the  general  category   of  Municipal  Bonds   are
participation  certificates  issued  by government  authorities  or  entities to
finance the acquisition  or construction of  equipment, land and/or  facilities.
The  certificates represent participations  in a lease,  an installment purchase
contract or a conditional sales contract (hereinafter collectively called "lease
obligations") relating to  such equipment,  land or  facilities. Although  lease
obligations  do not constitute  general obligations of the  issuer for which the
issuer's unlimited taxing  power is  pledged, a lease  obligation is  frequently
backed by the issuer's covenant to budget for, appropriate and make the payments
due  under  the lease  obligation.  However, certain  lease  obligations contain
"non-appropriation" clauses which provide that  the issuer has no obligation  to
make  lease or  installment purchase  payments in  future years  unless money is
appropriated for such  purpose on a  yearly basis. Although  "non-appropriation"
lease  obligations  are  secured  by the  leased  property,  disposition  of the
property in the  event of  foreclosure might prove  difficult. These  securities
represent  a relatively  new type  of financing that  has not  yet developed the
depth of  marketability associated  with more  conventional securities.  Certain
investments  in lease obligations  may be illiquid.  The Fund may  not invest in
illiquid lease obligations  if such  investments, together  with other  illiquid
investments,  would exceed 15% of the Fund's  net assets. The Fund may, however,
invest without regard to such limitation in lease obligations which the Manager,
pursuant to guidelines  which have  been adopted by  the Board  of Trustees  and
subject  to the supervision of  the Board, determines to  be liquid. The Manager
will deem  lease  obligations liquid  if  they  are publicly  offered  and  have
received  an investment  grade rating  of Baa  or better  by Moody's,  or BBB or
better by Standard & Poor's or Fitch. Unrated lease obligations, or those  rated
below investment grade, will be considered liquid if the obligations come to the
market  through an  underwritten public  offering and  at least  two dealers are
willing to give competitive bids. In reference to the latter, the Manager  must,
among  other  things,  also  review  the  creditworthiness  of  the municipality
obligated to make payment under the lease obligation and make certain  specified
determinations  based on  such factors  as the existence  of a  rating or credit
enhancement such  as  insurance, the  frequency  of  trades or  quotes  for  the
obligation and the willingness of dealers to make a market in the obligation.
    

    Federal  tax  legislation has  limited  the types  and  volume of  bonds the
interest on which  qualifies for a  Federal income tax  exemption. As a  result,
this  legislation and legislation which may be  enacted in the future may affect
the availability of Municipal Bonds for investment by the Fund.

   
WHEN-ISSUED SECURITIES AND DELAYED DELIVERY TRANSACTIONS
    
   
    The Fund may purchase or sell Municipal Bonds on a delayed delivery basis or
a when-issued  basis at  fixed  purchase terms.  These transactions  arise  when
securities  are purchased or sold  by the Fund with  payment and delivery taking
place in the future. The purchase will  be recorded on the date the Fund  enters
into the commitment and the value of the obligation will thereafter be reflected
in the calculation of the Fund's net asset value. The value of the obligation on
the  delivery  date may  be more  or less  than its  purchase price.  A separate
account of the Fund will be  established with its custodian consisting of  cash,
cash  equivalents or high grade, liquid Municipal Bonds having a market value at
all times at least equal to the amount of the forward commitment.
    

CALL RIGHTS

    The Fund may  purchase a  Municipal Bond  issuer's right  to call  all or  a
portion  of  such Municipal  Bond  for mandatory  tender  for purchase  (a "Call
Right"). A holder of a Call Right may exercise such right to require a mandatory
tender  for  the  purchase  of  related  Municipal  Bonds,  subject  to  certain
conditions.  A Call  Right that is  not exercised  prior to the  maturity of the
related Municipal Bond will expire without value.

                                       14
<PAGE>
   
The economic effect  to holding both  the Call Right  and the related  Municipal
Bond  is  identical to  holding  a Municipal  Bond  as a  non-callable security.
Certain investments in such obligations may be illiquid. The Fund may not invest
in such illiquid obligations if  such investments, together with other  illiquid
investments, would exceed 15% of the Fund's net assets.
    

FINANCIAL FUTURES TRANSACTIONS AND OPTIONS
   
    The  Fund  is  authorized  to  purchase  and  sell  certain  exchange traded
financial futures  contracts  ("financial  futures contracts")  solely  for  the
purpose  of hedging its investments in Municipal Bonds against declines in value
and to hedge against increases in the cost of securities it intends to purchase.
However, any transactions involving financial futures or options (including puts
and calls associated therewith) will be in accordance with the Fund's investment
policies and limitations. A financial futures contract obligates the seller of a
contract to deliver and the purchaser of a contract to take delivery of the type
of financial instrument covered by the  contract, or in the case of  index-based
futures  contracts to make  and accept a  cash settlement, at  a specific future
time for a specified price. A sale of financial futures contracts may provide  a
hedge  against  a decline  in  the value  of  portfolio securities  because such
depreciation may be offset, in whole or in part, by an increase in the value  of
the position in the financial futures contracts. A purchase of financial futures
contracts  may provide  a hedge  against an increase  in the  cost of securities
intended to be purchased, because such  appreciation may be offset, in whole  or
in  part, by an increase in the value  of the position in the futures contracts.
Distributions, if any, of net long-term capital gains from certain  transactions
in  futures or options are taxable at  long-term capital gains rates for Federal
income tax purposes, regardless of the length of time the shareholder has  owned
Fund shares. See "Distributions and Taxes -- Taxes".
    

    The Fund deals in financial futures contracts traded on the Chicago Board of
Trade  based on The Bond Buyer Municipal Bond Index, a price-weighted measure of
the market value of 40 large, recently issued tax-exempt bonds. There can be  no
assurance,  however, that a liquid secondary  market will exist to terminate any
particular financial  futures  contract at  any  specific  time. If  it  is  not
possible  to close a  financial futures position  entered into by  the Fund, the
Fund would continue  to be  required to make  daily cash  payments of  variation
margin in the event of adverse price movements. In such a situation, if the Fund
has  insufficient cash, it may  have to sell portfolio  securities to meet daily
variation margin requirements at a time when it may be disadvantageous to do so.
The inability to close  financial futures positions also  could have an  adverse
impact  on the Fund's  ability to hedge  effectively. There is  also the risk of
loss by the Fund of margin deposits in the event of bankruptcy of a broker  with
whom the Fund has an open position in a financial futures contract.

    The  Fund  may  purchase  and  sell  financial  futures  contracts  on  U.S.
Government securities  and write  and  purchase put  and  call options  on  such
futures  contracts  as a  hedge  against adverse  changes  in interest  rates as
described more fully in the Statement of Additional Information. With respect to
U.S. Government  securities, currently  there  are financial  futures  contracts
based  on  long-term U.S.  Treasury bonds,  Treasury notes,  Government National
Mortgage Association ("GNMA") Certificates and three-month U.S. Treasury bills.

    Subject to policies  adopted by the  Trustees, the Fund  also may engage  in
other  financial  futures contracts  transactions and  options thereon,  such as
financial futures contracts or options on other municipal bond indexes which may
become available if the Manager of the Fund and the Trustees of the Trust should
determine that there is normally a sufficient correlation between the prices  of
such futures contracts and the Municipal Bonds in which the Fund invests to make
such hedging appropriate.

                                       15
<PAGE>
    Utilization of futures transactions and options thereon involves the risk of
imperfect  correlation  in  movements  in the  price  of  futures  contracts and
movements in the price of the security which is the subject of the hedge. If the
price of the futures contract moves more or less than the price of the  security
that  is the subject of the hedge, the Fund will experience a gain or loss which
will not be completely offset by movements in the price of such security.  There
is  a  risk of  imperfect correlation  where  the securities  underlying futures
contracts have  different  maturities,  ratings or  geographic  mixes  than  the
security being hedged. In addition, the correlation may be affected by additions
to  or deletions from the index which serves  as a basis for a financial futures
contract.  Finally,  in  the  case  of  futures  contracts  on  U.S.  Government
securities and options on such futures contracts, the anticipated correlation of
price movements between the U.S. Government securities underlying the futures or
options  and Municipal Bonds  may be adversely  affected by economic, political,
legislative  or  other  developments  which  have  a  disparate  impact  on  the
respective markets for such securities.

    Under  regulations of the Commodity Futures Trading Commission ("CFTC"), the
futures trading activities described  herein will not result  in the Fund  being
deemed  to be  a "commodity pool",  as defined under  such regulations, provided
that the  Fund adheres  to certain  restrictions. In  particular, the  Fund  may
purchase  and  sell futures  contracts  and options  thereon  (i) for  bona fide
hedging purposes, and (ii)  for non-hedging purposes,  if the aggregate  initial
margin  and  premiums  required to  establish  positions in  such  contracts and
options does not  exceed 5%  of the liquidation  value of  the Fund's  portfolio
assets after taking into account unrealized profits and unrealized losses on any
such  contracts  and options.  (However, as  stated above,  the Fund  intends to
engage in options and  futures transactions only  for hedging purposes.)  Margin
deposits  may consist  of cash  or securities acceptable  to the  broker and the
relevant contract market.

    When the  Fund purchases  a futures  contract,  or writes  a put  option  or
purchases  a  call option  thereon, it  will  maintain an  amount of  cash, cash
equivalents (e.g.,  high  grade commercial  paper  and daily  tender  adjustable
notes)  or  short-term,  high-grade,  fixed-income  securities  in  a segregated
account with the  Fund's custodian, so  that the amount  so segregated plus  the
amount  of initial and variation margin held in the account of its broker equals
the market value of the futures contracts, thereby ensuring that the use of such
futures contract  is unleveraged.  It is  not anticipated  that transactions  in
futures contracts will have the effect of increasing portfolio turnover.

    Although certain risks are involved in options and futures transactions, the
Manager believes that, because the Fund will engage in futures transactions only
for  hedging purposes,  the futures  portfolio strategies  of the  Fund will not
subject the  Fund to  certain risks  frequently associated  with speculation  in
futures transactions. The Fund must meet certain Federal income tax requirements
under  the Internal Revenue  Code of 1986,  as amended (the  "Code") in order to
qualify for the special tax  treatment afforded regulated investment  companies,
including  a requirement that less than 30%  of its gross income be derived from
the sale or  other disposition of  securities held for  less than three  months.
Additionally,  the Fund is required to meet certain diversification requirements
under the Code.

    The liquidity of a secondary market  in a futures contract may be  adversely
affected  by "daily price fluctuation limits" established by commodity exchanges
which limit  the amount  of fluctuation  in a  futures contract  price during  a
single  trading day. Once the  daily limit has been  reached in the contract, no
trades may be  entered into at  a price  beyond the limit,  thus preventing  the
liquidation  of open futures positions. Prices have in the past moved beyond the
daily limit on a number of consecutive trading days.

                                       16
<PAGE>
    The successful use of transactions in futures also depends on the ability of
the  Manager to  forecast correctly  the direction  and extent  of interest rate
movements within a  given time frame.  To the extent  these rates remain  stable
during  the period in which a futures contract is held by the Fund or moves in a
direction opposite  to that  anticipated, the  Fund may  realize a  loss on  the
hedging transaction which is not fully or partially offset by an increase in the
value  of portfolio securities.  As a result,  the Fund's total  return for such
period may  be less  than if  it had  not engaged  in the  hedging  transaction.
Furthermore, the Fund will only engage in hedging transactions from time to time
and  may not necessarily  be engaging in hedging  transactions when movements in
interest rates occur.

    Reference is made  to the  Statement of Additional  Information for  further
information on financial futures contracts and certain options thereon.

   
REPURCHASE AGREEMENTS
    

   
    As  Temporary Investments,  the Fund  may invest  in securities  pursuant to
repurchase agreements. Repurchase  agreements may  be entered into  only with  a
member bank of the Federal Reserve System or a primary dealer in U.S. Government
securities  or an affiliate  thereof. Under such  agreements, the seller agrees,
upon entering into the contract, to repurchase  the security from the Fund at  a
mutually  agreed upon time  and price, thereby determining  the yield during the
term of the agreement.  This results in  a fixed rate  of return insulated  from
market  fluctuations during such  period. The Fund may  not invest in repurchase
agreements maturing in more than seven  days if such investments, together  with
the  Fund's  other illiquid  investments,  would exceed  15%  of the  Fund's net
assets. In the event of  a default by the  seller under a repurchase  agreement,
the Fund may suffer time delays and incur costs on possible losses in connection
with the disposition of the underlying securities.
    

INVESTMENT RESTRICTIONS

   
    CURRENT  INVESTMENT  RESTRICTIONS.    The  Fund  has  adopted  a  number  of
restrictions and policies relating  to the investment of  the Fund's 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, as  defined  in the  1940  Act. Among  the more
significant restrictions, the Fund  may not: (i)  purchase any securities  other
than  securities referred to  under "Investment Objective  and Policies" herein;
(ii) purchase securities  of other  investment companies,  except in  connection
with certain specified transactions and with respect to investments of up to 10%
of  the Fund's  total assets in  securities of  closed-end investment companies;
(iii) borrow amounts in excess of 20% of its total assets taken at market  value
(including the amount borrowed), and then only from banks as a temporary measure
for  extraordinary or emergency purposes [The  Fund will not purchase securities
while borrowings are outstanding]; (iv) mortgage, pledge, hypothecate or in  any
manner transfer as security for indebtedness any securities owned or held by the
Fund  except in  connection with certain  specified transactions;  (v) invest in
securities which  cannot  be readily  resold  because of  legal  or  contractual
restrictions  or  which  are  not  readily  marketable,  including  individually
negotiated  loans  that  constitute  illiquid  investments  and  illiquid  lease
obligations,  and  in  repurchase  agreements and  purchase  and  sale contracts
maturing in  more than  seven  days, if,  regarding  all such  securities  taken
together,  more than 15% of its net assets (taken at market value at the time of
each investment) would be invested in such securities; (vi) invest more than 10%
of its total assets (taken  at market value at the  time of each investment)  in
industrial  revenue bonds where the entity supplying the revenues from which the
issue  is  to  be  paid,  and   the  guarantor  of  the  obligation,   including
predecessors,  each have a record of  less than three years' continuous business
operation; and (vii) invest more than 25%  of its total assets (taken at  market
    

                                       17
<PAGE>
value at the time of each investment) in securities of issuers in any particular
industry (other than U.S. Government securities or Government agency securities,
Municipal Bonds and Non-Municipal Tax-Exempt Securities).

   
    The  Board of Trustees  of the Trust, at  a meeting held  on August 3, 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 1940 Act and
applicable state securities regulations,  help promote operational  efficiencies
and  facilitate monitoring of compliance.  The investment objective 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.
    

   
    The Fund is  classified as non-diversified  within the meaning  of the  1940
Act,  which means that the Fund is not limited by the 1940 Act in the proportion
of its assets that it may invest in obligations of a single issuer. However, the
Fund's investments will be limited so  as to qualify as a "regulated  investment
company"  for purposes  of the  Internal Revenue Code  of 1986,  as amended (the
"Code"). See "Taxes". To qualify, among other requirements, the Trust will limit
the Fund's investments  so that, at  the close  of each quarter  of the  taxable
year,  (i) not more than 25% of the market value of the Fund's total assets will
be invested in the securities of a  single issuer, and (ii) with respect to  50%
of the market value of its total assets, not more than 5% of the market value of
its  total assets will be invested in the  securities of a single issuer and the
Fund will not own more than 10% of the outstanding voting securities of a single
issuer. [For purposes of this restriction,  the Fund will regard each state  and
each  political subdivision,  agency or instrumentality  of such  state and each
multi-state agency of  which such state  is a member  and each public  authority
which  issues securities  on behalf  of a private  entity as  a separate issuer,
except that if  the security  is backed  only by the  assets and  revenues of  a
non-government  entity then the entity with  the ultimate responsibility for the
payment of interest  and principal may  be regarded as  the sole issuer.]  These
tax-related  limitations may  be changed  by the  Trustees of  the Trust  to the
extent necessary to comply with changes to the Federal tax requirements. A  fund
which  elects to be classified as "diversified"  under the 1940 Act must satisfy
the foregoing 5% and 10% requirements with  respect to 75% of its total  assets.
To  the extent  that the Fund  assumes large  positions in the  obligations of a
small number of  issuers, the  Fund's total return  may fluctuate  to a  greater
extent  than  that  of a  diversified  company as  a  result of  changes  in the
financial condition or in the market's assessment of the issuers.
    

    Investors are  referred to  the Statement  of Additional  Information for  a
complete description of the Fund's investment restrictions.

MANAGEMENT AND ADVISORY ARRANGEMENTS

   
    Fund Asset Management, L.P. (the "Manager"),  which is an affiliate of  MLAM
and  is owned and controlled by ML  & Co., a financial services holding company,
acts as the manager for the Fund and provides the Fund with management services.
The Manager or  MLAM acts  as the  investment adviser  for more  than 100  other
registered investment companies. MLAM also provides investment advisory services
to  individuals and institutional  accounts. As of August  31, 1994, the Manager
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 Manager.
    

    Subject to the direction of the Trustees, the Manager is responsible for the
actual management  of the  Fund's portfolio  and constantly  reviews the  Fund's
holdings  in light  of its  own research analysis  and that  from other relevant
sources. The  responsibility  for  making  decisions to  buy,  sell  or  hold  a
particular  security rests with the Manager. The Manager performs certain of the
other administrative services  and provides  all the  office space,  facilities,
equipment and necessary personnel for management of the Fund.

    Vincent  R. Giordano and Kenneth A. Jacob are the Portfolio Managers for the
Fund. Vincent R. Giordano has been a  Portfolio Manager of the Manager and  MLAM
since  1977 and  a Senior  Vice President  of the  Manager and  MLAM since 1984.
Kenneth A. Jacob has been a Vice President of the Manager and MLAM since 1984.

    Pursuant to the management  agreement between the Manager  and the Trust  on
behalf  of the  Fund (the  "Management Agreement"),  the Manager  is entitled to
receive from the Fund a monthly fee based upon the

                                       19
<PAGE>
   
average daily net assets of the Fund at the following annual rates: 0.55% of the
average daily net assets not exceeding $500 million; 0.525% of the average daily
net assets exceeding $500 million but  not exceeding $1.0 billion; and 0.50%  of
the average daily net assets exceeding $1.0 billion. For the year ended July 31,
1994,  the total fee paid by the Fund  to the Manager was $383,179, all of which
was voluntarily  waived (based  on  average net  assets of  approximately  $69.9
million).
    

   
    The Management Agreement obligates the Fund to pay certain expenses incurred
in  the Fund's  operations, including, among  other things,  the management fee,
legal and audit  fees, unaffiliated  Trustees' fees  and expenses,  registration
fees,  custodian and  transfer agency  fees, accounting  and pricing  costs, and
certain of the costs of printing proxies, shareholder reports, prospectuses  and
statements  of additional information.  Accounting services are  provided to the
Fund by  the Manager,  and the  Fund reimburses  the Manager  for its  costs  in
connection  with  such services.  For the  year  ended July  31, 1994,  the Fund
reimbursed the Manager $45,746 for accounting services. For the year ended  July
31,  1994, the ratio of  total expenses, excluding distribution  fees and net of
reimbursement, to average net assets  was .31% for Class  A shares and .31%  for
Class B shares; no Class C or Class D shares had been issued during that year.
    

TRANSFER AGENCY SERVICES

   
    Financial   Data  Services,  Inc.   (the  "Transfer  Agent"),   which  is  a
wholly-owned subsidiary of ML & Co., acts as the Trust's transfer agent pursuant
to a  transfer  agency, dividend  disbursing  agency and  shareholder  servicing
agency  agreement (the  "Transfer Agency  Agreement"). Pursuant  to the Transfer
Agency Agreement, the Transfer Agent  is responsible for the issuance,  transfer
and  redemption  of  shares  and  the  opening  and  maintenance  of shareholder
accounts. Pursuant to the Transfer Agency Agreement, the Fund pays the  Transfer
Agent  an annual fee  of $11.00 per Class  A or Class  D shareholder account and
$14.00 per Class B  or Class C  shareholder account, and  the Transfer Agent  is
entitled  to reimbursement from the Fund  for out-of-pocket expenses incurred by
the Transfer Agent under the Transfer Agency Agreement. For the year ended  July
31,  1994, the Fund paid  the Transfer Agent a total  fee of $42,128 pursuant to
the Transfer Agency Agreement for providing transfer agency services.
    

                               PURCHASE OF SHARES

   
    Merrill Lynch Funds Distributor, Inc.  (the "Distributor"), an affiliate  of
both  MLAM and Merrill Lynch, acts as the Distributor of the shares of the Fund.
Shares of the  Fund are  offered continuously for  sale by  the Distributor  and
other  eligible securities dealers (including Merrill Lynch). Shares of the Fund
may be purchased from securities dealers or by mailing a purchase order directly
to the Transfer Agent. The minimum  initial purchase is $1,000, and the  minimum
subsequent purchase is $50.
    

   
    The  Fund is offering its shares in  four classes at a public offering price
equal to  the next  determined net  asset  value per  share plus  sales  charges
imposed either at the time of purchase or on a deferred basis depending upon the
class  of shares selected by the investor under the Merrill Lynch Select Pricing
System, as described below. The applicable offering price for purchase orders is
based upon the net asset value of the Fund next determined after receipt of  the
purchase orders by the Distributor. As to purchase orders received by securities
dealers  prior to 4:15 P.M., New York time, which includes orders received after
the determination  of  net asset  value  on  the previous  day,  the  applicable
offering  price will be based on the net asset value as of 4:15 P.M., on the day
the orders are placed with the Distributor, provided the orders are received  by
the  Distributor prior to 4:30 P.M., New York time, on that day. If the purchase
orders are not received prior to
    

                                       20
<PAGE>
   
4:30 P.M., New  York time,  such orders  shall be  deemed received  on the  next
business  day. The Trust or the  Distributor may suspend the continuous offering
of the Fund's shares of any class at  any time in response to conditions in  the
securities  markets or  otherwise and may  thereafter resume  such offering from
time to time. Any order may be rejected by the Distributor or the Trust. Neither
the Distributor nor  the dealers  are permitted  to withhold  placing orders  to
benefit  themselves by a price change. Merrill  Lynch may charge its customers a
processing fee (presently $4.85) to confirm a sale of shares to such  customers.
Purchases  directly through  the Fund's  Transfer Agent  are not  subject to the
processing fee.
    

   
    The Fund  issues four  classes  of shares  under  the Merrill  Lynch  Select
Pricing  System, which permits each investor  to choose the method of purchasing
shares that the  investor believes is  most beneficial given  the amount of  the
purchase,  the length of time the investor  expects to hold the shares and other
relevant circumstances. Shares  of Class  A and Class  D are  sold to  investors
choosing the initial sales charge alternatives and shares of Class B and Class C
are sold to investors choosing the deferred sales charge alternatives. Investors
should  determine  whether  under  their  particular  circumstances  it  is more
advantageous to incur  an initial  sales charge or  to have  the entire  initial
purchase price invested in the Fund with the investment thereafter being subject
to  a  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 System is set
forth under "Merrill Lynch Select Pricing-SM- System" on page 3.
    

   
    Each  Class A, Class B, Class C and  Class D share of the Fund represents an
identical interest in  the investment  portfolio of the  Fund and  has the  same
rights, except that Class B, Class C and Class D shares bear the expenses of the
ongoing  account  maintenance fees,  and Class  B  and Class  C shares  bear the
expenses of  the  ongoing  distribution  fees  and  the  additional  incremental
transfer agency costs resulting from the deferred sales charge arrangements. The
deferred  sales charges and account maintenance fees that are imposed on Class B
and Class C shares, as well as the account maintenance fees that are imposed  on
Class  D shares, will be imposed directly  against those classes and not against
all assets of the Fund  and, accordingly, such charges  will not affect the  net
asset  value of any other class or have any impact on investors choosing another
sales charge option. Dividends paid by the Fund for each class of shares will be
calculated in the  same manner  at the  same time and  will differ  only to  the
extent  that  account  maintenance  and distribution  fees  and  any incremental
transfer agency costs relating  to a particular class  are borne exclusively  by
that  class. Class  B, Class  C and  Class D  shares each  have exclusive voting
rights with respect to the Rule 12b-1 distribution plan adopted with respect  to
such  class pursuant to  which account maintenance  and/or distribution fees are
paid.  See  "Distribution  Plans"  below.  Each  class  has  different  exchange
privileges. See "Shareholder Services -- Exchange Privilege".
    

   
    Investors  should understand  that the purpose  and function  of the initial
sales charges with respect to Class A and  Class D shares are the same as  those
of the deferred sales charges with respect to Class B and Class C shares in that
the  sales charges  applicable to  each class provide  for the  financing of the
distribution of the shares of  the Fund. The distribution-related revenues  paid
with  respect  to  a  class  will  not  be  used  to  finance  the  distribution
expenditures  of   another  class.   Sales  personnel   may  receive   different
compensation for selling different classes of shares. Investors are advised that
only Class A and Class D shares may be available for purchase through securities
dealers, other than Merrill Lynch, which are eligible to sell shares.

(1)  Initial sales charges are imposed at  the time of purchase as a  percentage
     of the offering price. CDSCs may be imposed if the redemption occurs within
     the  applicable CDSC time period. The charge  will be assessed on an amount
     equal to the lesser of the proceeds of redemption or the cost of the shares
     being redeemed.
(2)  Offered only to eligible investors. See "Initial Sales Charge  Alternatives
     -- Class A and Class D Shares -- Eligible Class A Investors".
(3)  Reduced  for  purchases of  $25,000  or more.  Class  A and  Class  D share
     purchases of $1,000,000  or more  may not be  subject to  an initial  sales
     charge but instead may be subject to a CDSC if redeemed within 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  an eight year  conversion period.  If Class B
     shares of the Fund are exchanged for Class B shares of another MLAM-advised
     mutual fund,  the  conversion  period  applicable to  the  Class  B  shares
     acquired  in the exchange will apply, and the holding period for the shares
     exchanged will be tacked onto the holding period for the shares acquired.

     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 annual rates: 0.75% on purchases of
     $1,000,000 to $2,500,000; 0.40% on purchases of $2,500,001 to $3,500,000;
     0.25% on purchases of $3,500,001 to $5,000,000; and 0.20% on purchases of
     more than $5,000,000 in lieu of paying an initial sales charge. The charge
     will be assessed on an amount equal to the lesser of the proceeds of the
     redemption or the cost of the shares being redeemed.
</TABLE>
    

   
    The  Distributor may  reallow discounts to  selected dealers  and retain the
balance over such  discounts. At times  the Distributor may  reallow the  entire
sales charge to such dealers. Since securities dealers selling Class A and Class
D  shares of  the Fund  will receive  a concession  equal to  most of  the sales
charge, they may be deemed to be underwriters under the Securities Act of  1933,
as  amended. During the fiscal  year ended July 31,  1994, the Fund sold 557,125
Class A shares for aggregate net proceeds of $5,752,822. The gross sales charges
for the sale of Class A shares of the Fund for that year were $57,585, of  which
$7,508  and  $50,077  were  received  by  the  Distributor  and  Merrill  Lynch,
respectively. For the fiscal year ended July 31, 1994, the Distributor  received
no  CDSCs with respect to  redemption within one year  after purchase of Class A
shares purchased subject to front-end sales charge waivers.
    

   
    ELIGIBLE CLASS A INVESTORS.  Class A  shares are offered to a limited  group
of  investors  and  also  will  be  issued  upon  reinvestment  of  dividends on
outstanding Class A  shares. Investors that  currently own Class  A shares in  a
shareholder  account 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 ML & Co. 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
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
    

                                       23
<PAGE>
   
offered at net asset value to shareholders of Merrill Lynch Senior Floating Rate
Fund, Inc. who wish to reinvest the net proceeds from a sale of certain of their
shares of  common stock  of Merrill  Lynch Senior  Floating Rate  Fund, Inc.  in
shares of such funds.
    

   
    REDUCED  INITIAL SALES CHARGES.   No initial sales  charges are imposed upon
Class A and Class D shares issued  as a result of the automatic reinvestment  of
dividends or capital gains distributions. Class A and Class D sales charges also
may be reduced under a Right of Accumulation and a Letter of Intention.
    

   
    Class  A shares are offered  at net asset value  to certain eligible Class A
investors as set forth above under "Eligible Class A Investors".
    

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

   
    Additional information concerning these reduced initial sales charges is set
forth in the Statement of Additional Information.
    

   
DEFERRED SALES CHARGE ALTERNATIVES--CLASS B AND CLASS C SHARES
    
   
    INVESTORS CHOOSING THE  DEFERRED SALES CHARGE  ALTERNATIVES SHOULD  CONSIDER
CLASS  B SHARES IF  THEY INTEND TO HOLD  THEIR SHARES FOR  AN EXTENDED PERIOD OF
TIME AND CLASS  C SHARES IF  THEY ARE UNCERTAIN  AS TO THE  LENGTH OF TIME  THEY
INTEND TO HOLD THEIR ASSETS IN MLAM-ADVISED MUTUAL FUNDS.
    

   
    The  public  offering price  of Class  B  and Class  C shares  for investors
choosing the deferred sales charge alternatives is the next determined net asset
value per  share  without the  imposition  of a  sales  charge at  the  time  of
purchase.  As discussed below, Class  B shares are subject  to a four year CDSC,
while Class C  shares are subject  only to a  one year 1.0%  CDSC. On the  other
hand,  approximately ten  years after  Class B shares  are issued,  such Class B
shares, together with shares issued  upon dividend reinvestment with respect  to
those  shares, are automatically converted  into Class D shares  of the Fund and
thereafter will be subject to lower continuing fees. See "Conversion of Class  B
Shares  to Class D Shares" below. Both Class B and Class C shares are subject to
an account maintenance fee of 0.25% of net assets and Class B and Class C shares
are subject to distribution fees of 0.25% and 0.35%, respectively, of net assets
as discussed below  under "Distribution  Plans". The proceeds  from the  account
maintenance  fees are used to compensate  Merrill Lynch for providing continuing
account maintenance activities.
    

   
    Class B and Class C shares are sold without an initial sales charge so  that
the  Fund  will receive  the  full amount  of  the investor's  purchase payment.
Merrill Lynch  compensates its  financial consultants  for selling  Class B  and
Class  C shares at  the time of  purchase from its  own funds. See "Distribution
Plans" 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 the dealer's own funds. The combination of  the
CDSC  and the ongoing  distribution fee facilitates  the ability of  the Fund to
sell the Class B and Class C shares without a sales charge being deducted at the
time of purchase. Approximately  ten years after issuance,  Class B shares  will
convert automatically into Class D shares of the
    

                                       24
<PAGE>
   
Fund,  which are subject to a lower  account maintenance fee and no distribution
fee; Class  B shares  of  certain other  MLAM-advised  mutual funds  into  which
exchanges   may  be  made  convert  into  Class  D  shares  automatically  after
approximately eight years. If Class B shares of the Fund are exchanged for Class
B shares of another MLAM-advised  mutual fund, the conversion period  applicable
to  the Class  B shares  acquired in  the exchange  will apply,  and the holding
period for the shares exchanged will be  tacked onto the holding period for  the
shares acquired.
    

   
    Imposition  of the  CDSC and  the distribution  fee on  Class B  and Class C
shares is limited by the NASD asset-based sales charge rule. See "Limitations on
the Payment of  Deferred Sales  Charges" below.  The proceeds  from the  ongoing
account  maintenance  fee are  used to  compensate  Merrill Lynch  for providing
continuing account  maintenance activities.  Class B  shareholders of  the  Fund
exercising  the  exchange  privilege described  under  "Shareholder  Services --
Exchange Privilege" will continue to be subject to the Fund's CDSC schedule,  if
such  schedule is higher than  the CDSC schedule relating  to the Class B shares
acquired as a result of the exchange.
    

   
    CONTINGENT DEFERRED SALES CHARGES--CLASS B SHARES.  Class B shares which are
redeemed within four years of purchase may be subject to a CDSC at the rates set
forth below charged as  a percentage of the  dollar amount subject thereto.  The
charge  will be  assessed on an  amount equal to  the lesser of  the proceeds of
redemption or the cost of the  shares being redeemed. Accordingly, no CDSC  will
be  imposed on increases in net asset value above the initial purchase price. In
addition, no  CDSC will  be  assessed on  shares  derived from  reinvestment  of
dividends or capital gains distributions.
    

   
    The following table sets forth the Class B CDSC:

</TABLE>

   
    For  the fiscal year ended July 31,  1994, the Distributor received CDSCs of
$100,415 with respect to redemptions of Class B shares.
    

   
    In determining whether a CDSC is applicable to a redemption, the calculation
will be determined  in the  manner that results  in the  lowest applicable  rate
being  charged. Therefore, it  will be assumed  that the redemption  is first of
shares held  for over  four years  until  such time  as the  CDSC is  no  longer
applicable   or  shares  acquired  pursuant  to  reinvestment  of  dividends  or
distributions and then of shares held  longest during the four-year period.  The
charge will not be applied to dollar amounts representing an increase in the net
asset   value  since  the  time  of  purchase.  A  transfer  of  shares  from  a
shareholder's account to another account will be assumed to be made in the  same
order as a redemption.
    

    To  provide an example, assume  an investor purchased 100  shares at $10 per
share (at a cost of $1,000) and in the third year after purchase, the net  asset
value    per   share   is   $12   and,    during   such   time,   the   investor

                                       25
<PAGE>
   
has acquired 10 additional  shares upon dividend reinvestment.  If at such  time
the  investor makes  his first  redemption of 50  shares (proceeds  of $600), 10
shares will not  be subject  to charge  because of  dividend reinvestment.  With
respect  to the remaining 40 shares, the  charge is applied only to the original
cost of $10  per share and  not to  the increase in  net asset value  of $2  per
share. Therefore, $400 of the $600 redemption proceeds will be charged at a rate
of 2.0% (the applicable rates 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  1986, as amended) of  a
shareholder. Additional information concerning the waiver of the Class B CDSC is
set forth in the Statement of Additional Information.
    

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

   
    In determining whether  a Class C  CDSC is applicable  to a redemption,  the
calculation will be determined in the manner that results in the lowest possible
rate  being charged. Therefore, it will be  assumed that the redemption is first
of shares held for over one year or shares acquired pursuant to reinvestment  of
dividends  or distributions and then of  shares held longest during the one-year
period. The  charge  will not  be  applied  to dollar  amounts  representing  an
increase in the net asset value since the time of purchase. A transfer of shares
from  a shareholder's account to  another account will be  assumed to be made in
the same order as a redemption.
    

   
    CONVERSION OF CLASS  B SHARES TO  CLASS D SHARES.   After approximately  ten
years  (the "Conversion Period"), Class B shares will be converted automatically
into Class  D shares  of the  Fund. Class  D shares  are subject  to an  ongoing
account  maintenance  fee of  0.10% of  net assets  but are  not subject  to the
distribution fee that is borne by Class B shares. Automatic conversion of  Class
B  shares  into Class  D shares  will occur  at  least once  each month  (on the
"Conversion Date") on the basis of the  relative net asset values of the  shares
of  the two classes on the Conversion  Date, without the imposition of any sales
load, fee or other charge. Conversion of  Class B shares to Class D shares  will
not be deemed a purchase or sale of the shares for Federal income tax purposes.
    

   
    In  addition, shares purchased through reinvestment  of dividends on Class B
shares also will convert  automatically to Class D  shares. The Conversion  Date
for  dividend reinvestment  shares will  be calculated  taking into  account the
length of  time the  shares underlying  such dividend  reinvestment shares  were
outstanding. If at a Conversion Date the conversion of Class B shares to Class D
shares  of the Fund  in a single account  will result in less  than $50 worth of
Class B shares being left in the account, all of the Class B shares of the  Fund
held  in the account on the Conversion Date  will be converted to Class D shares
of the Fund.
    

   
    Shares 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
    

                                       26
<PAGE>
   
certificates are not received by the Transfer  Agent at least one week prior  to
the  Conversion Date, the related Class B  shares will convert to Class D shares
on the next scheduled Conversion Date after such certificates are delivered.
    

   
    In general, Class B shares of equity MLAM-advised mutual funds will  convert
approximately  eight years after initial purchase, and Class B shares of taxable
and tax-exempt fixed income MLAM-advised mutual funds will convert approximately
ten  years  after  initial  purchase.  If,  during  the  Conversion  Period,   a
shareholder  exchanges Class B  shares with an  eight-year Conversion Period for
Class B shares with a ten-year Conversion Period, or vice versa, the  Conversion
Period applicable to the Class B shares acquired in the exchange will apply, and
the  holding period  for the  shares exchanged will  be tacked  onto the holding
period for the shares acquired.
    

   
DISTRIBUTION PLANS
    
   
    The Fund has adopted  separate distribution plans for  Class B, Class C  and
Class  D shares pursuant to Rule 12b-1  under the Investment Company Act (each a
"Distribution Plan") with respect to the account maintenance and/or distribution
fees paid by the Fund to the Distributor with respect to such classes. The Class
B and Class C Distribution Plans provide for the payment of account  maintenance
fees  and distribution fees, and the Class  D Distribution Plan provides for the
payment of account maintenance fees.
    

   
    The Distribution Plans for Class B, Class C and Class D shares each  provide
that  the Fund pays the  Distributor an account maintenance  fee relating to the
shares of the  relevant class,  accrued daily and  paid monthly,  at the  annual
rates  of 0.25%, 0.25% and 0.10%, respectively,  of the average daily net assets
of the Fund attributable to shares of the relevant class in order to  compensate
the  Distributor and Merrill  Lynch (pursuant to  a sub-agreement) in connection
with account maintenance activities.
    

   
    The Distribution Plans for Class B and Class C shares each provide that  the
Fund  also pays the Distributor a distribution fee relating to the shares of the
relevant class, accrued daily and paid monthly, at the annual rate of 0.25%  and
0.35%, respectively, of the average daily net assets of the Fund attributable to
the  shares of  the relevant  class in order  to compensate  the Distributor and
Merrill Lynch  (pursuant  to  a sub-agreement)  for  providing  shareholder  and
distribution  services, and bearing certain distribution-related expenses of the
Fund, including payments to financial consultants for selling Class B and  Class
C  shares of the  Fund. The Distribution Plans  relating to Class  B and Class C
shares are designed to permit an investor to purchase Class B and Class C shares
through dealers without  the assessment of  an initial sales  charge and at  the
same  time  permit  the  dealer  to  compensate  its  financial  consultants  in
connection with the sale of the Class B and Class C shares. In this regard,  the
purpose  and function of the ongoing distribution fees and the CDSC are the same
as those of the  initial sales charge with  respect to the Class  A and Class  D
shares  of the Fund in that the deferred sales charges provide for the financing
of the distribution of the Fund's Class B and Class C shares.
    

   
    For the year  ended July  31, 1994, the  Fund paid  the Distributor  account
maintenance fees of $136,620 and distribution fees of $136,620 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 shares regardless of the amount of
expenses incurred and, accordingly, distribution-
    

                                       27
<PAGE>
   
related  revenues  from  the  Distribution  Plans  may  be  more  or  less  than
distribution-related expenses. Information with respect to the
distribution-related  revenues  and expenses  is presented  to the  Trustees for
their consideration in connection with their deliberations as to the continuance
of the Class  B and Class  C Distribution Plans.  This information is  presented
annually as of December 31 of each year on a "fully allocated accrual" basis and
quarterly  on a "direct expense and  revenue/cash" basis. On the fully allocated
accrual basis, revenues  consist of the  account maintenance fees,  distribution
fees,  the  CDSC and  certain other  related revenues,  and expenses  consist of
financial consultant compensation, branch  office and regional operation  center
selling  and transaction  processing expenses, advertising,  sales promotion and
marketing expenses,  corporate  overhead and  interest  expense. On  the  direct
expense  and  revenue/cash basis,  revenues consist  of the  account maintenance
fees, distribution  fees  and  CDSCs  and  the  expenses  consist  of  financial
consultant  compensation. As of December 31, 1993, the last date for which fully
allocated accrual  data  is  available, the  fully  allocated  accrual  expenses
incurred  by the Distributor and Merrill  Lynch exceeded fully allocated accrual
revenues for such period by approximately $1,258,000 (2.2% of Class B net assets
at that date).  As of December  31, 1993,  direct cash expenses  for the  period
since  the commencement of operations exceeded  direct cash revenues by $502,707
(.90% of Class  B net assets  at that date).  As of July  31, 1994, direct  cash
revenues  for the  period since the  commencement of  operations exceeded direct
cash expenses by $416,010 (.70% of Class B net assets at that date).
    

   
    The Fund  has no  obligation  with respect  to distribution  and/or  account
maintenance-related  expenses incurred by  the Distributor and  Merrill Lynch in
connection with Class B, Class C and  Class D shares, and there is no  assurance
that  the Trustees of the Trust will approve the continuance of the Distribution
Plans from  year  to year.  However,  the  Distributor intends  to  seek  annual
continuation  of the  Distribution Plans.  In their  review of  the Distribution
Plans, the Trustees will be asked  to take into consideration expenses  incurred
in  connection with the account maintenance and/or distribution of each class of
shares separately. The initial sales  charges, the account maintenance fee,  the
distribution fee and/or the CDSCs received with respect to one class will not be
used  to  subsidize  the  sale  of shares  of  another  class.  Payments  of the
distribution fee on Class B shares will terminate upon conversion of those Class
B shares  into  Class  D  shares  as set  forth  under  "Deferred  Sales  Charge
Alternatives  -- Class B and  Class C Shares -- Conversion  of Class B Shares to
Class D Shares".
    

   
    LIMITATIONS ON THE  PAYMENT OF DEFERRED  SALES CHARGES.   The maximum  sales
charge  rule in the Rules  of Fair Practice of the  NASD imposes a limitation on
certain asset-based sales  charges such  as the  distribution fee  and the  CDSC
borne  by the Class B  and Class C shares, but  not the account maintenance fee.
The maximum sales charge rule is applied separately to each class. As applicable
to the Fund, the maximum sales charge rule limits the aggregate of  distribution
fee  payments and CDSCs payable by the Fund to (1) 6.25% of eligible gross sales
of Class B shares  and Class C shares,  computed separately (defined to  exclude
shares  issued  pursuant  to  dividend  reinvestments  and  exchanges)  plus (2)
interest on the unpaid balance for the respective class, computed separately, at
the prime rate  plus 1%  (the unpaid balance  being the  maximum amount  payable
minus  amounts received from the payment of  the distribution fee and the CDSC).
In connection with the Class B shares, the Distributor has voluntarily agreed to
waive interest charges  on the  unpaid balance in  excess of  0.50% of  eligible
gross  sales.  Consequently,  the  maximum  amount  payable  to  the Distributor
(referred to as the "voluntary maximum")  in connection with the Class B  shares
is  6.75% of  eligible gross  sales. The Distributor  retains the  right to stop
waiving the interest charges  at any time. To  the extent payments would  exceed
the  voluntary  maximum,  the  Fund  will  not  make  further  payments  of  the
distribution fee with respect to  Class B shares and any  CDSCs will be paid  to
the Fund rather than to the
    

                                       28
<PAGE>
   
Distributor;  however, the  Fund will continue  to make payments  of the account
maintenance fee. In  certain circumstances  the amount payable  pursuant to  the
voluntary  maximum may exceed the amount payable under the NASD formula. In such
circumstances payments in excess  of the amount payable  under the NASD  formula
will not be made.
    

   
                              REDEMPTION OF SHARES
    

   
    The Trust is required to redeem for cash all shares of the Fund upon receipt
of a written request in proper form. The redemption price is the net asset value
per  share  next  determined  after  the initial  receipt  of  proper  notice of
redemption. Except for any CDSC which may be applicable, there will be no charge
for redemption if the redemption request is sent directly to the Transfer Agent.
Shareholders  liquidating  their  holdings  will  receive  upon  redemption  all
dividends  reinvested through the date of redemption. The value of shares at the
time of redemption may be more or less than the shareholder's cost, depending on
the market value of the securities held by the Fund at such time.
    

REDEMPTION

   
    A shareholder wishing to redeem shares may do so without charge by tendering
the shares  directly  to the  Transfer  Agent, 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  written  letter  requesting  redemption.  Proper  notice of
redemption in the case of shares for which certificates have been issued may  be
accomplished  by a written letter as noted above accompanied by certificates for
the shares to be redeemed. Redemption requests should not be sent to the  Trust.
The  notice in either  event requires the  signature(s) of all  persons in whose
name(s) the shares are registered, signed  exactly as such name(s) appear(s)  on
the  Transfer Agent's register. The signature(s)  on the redemption request must
be guaranteed by an "eligible guarantor institution" as such term is defined  in
Rule  17Ad-15  under  the  Securities  Exchange Act  of  1934,  as  amended, the
existence and validity of  which may be verified  by the Transfer Agent  through
the  use of industry  publications. Notarized signatures  are not sufficient. In
certain instances, the Transfer Agent may require additional documents such  as,
but  not  limited to,  trust  instruments, death  certificates,  appointments as
executor  or  administrator,  or   certificates  of  corporate  authority.   For
shareholders redeeming directly with the Transfer Agent, payments will be mailed
within seven days of receipt of a proper notice of redemption.
    

   
    At  various times the Trust may be requested to redeem Fund shares for which
it has not  yet received good  payment (e.g., cash,  Federal funds or  certified
check drawn on a United States bank). The Trust may delay or cause to be delayed
the  mailing of a redemption check until such time as it has assured itself that
good payment has been collected for the purchase of such Fund shares, which will
not exceed 10 days.
    

REPURCHASE

    The Trust also will  repurchase Fund shares  through a shareholder's  listed
securities  dealer. The  Trust normally  will accept  orders to  repurchase Fund
shares by wire or telephone  from dealers for their  customers at the net  asset
value  next computed after receipt of the order by the dealer, provided that the
request for repurchase is received by the dealer prior to the close of  business
on the New York Stock Exchange on the

                                       29
<PAGE>
   
day  received, and is received by the Fund  from such dealer not later than 4:30
P.M., New York time, on the same day. Dealers have the responsibility to  submit
such  repurchase requests to the Fund not later than 4:30 P.M., New York time in
order to obtain that day's closing price.
    

   
    The  foregoing   repurchase  arrangements   are  for   the  convenience   of
shareholders and do not involve a charge by the Trust (other than any applicable
CDSC).  Securities firms which  do not have selected  dealer agreements with the
Distributor, however, may  impose a  transaction charge on  the shareholder  for
transmitting the notice of repurchase to the Trust. Merrill Lynch may charge its
customers  a processing fee (presently $4.85)  to confirm a repurchase of shares
of such customers. Redemptions  directly through the  Fund's Transfer Agent  are
not  subject to the processing  fee. The Trust reserves  the right to reject any
order  for  repurchase,  which  right   of  rejection  might  adversely   affect
shareholders  seeking redemption  through the  repurchase procedure.  However, a
shareholder whose order for repurchase is rejected by the Trust may redeem  Fund
shares as set forth above.
    

REINSTATEMENT PRIVILEGE--CLASS A SHARES

   
    Shareholders  who  have redeemed  their Class  A  or Class  D shares  have a
one-time privilege to reinstate their accounts by purchasing Class A or Class  D
shares,  as the  case may be,  of the  Fund at net  asset value  without a sales
charge up to  the dollar  amount redeemed.  The reinstatement  privilege may  be
exercised  by sending a notice of exercise along  with a check for the amount to
be reinstated to the Transfer  Agent within 30 days  after the date the  request
for  redemption  was accepted  by  the Transfer  Agent  or the  Distributor. The
reinstatement will be  made at  the net asset  value per  share next  determined
after  the notice of reinstatement  is received and cannot  exceed the amount of
the redemption proceeds. The  reinstatement is a one-time  privilege and may  be
exercised  by  the Class  A  or Class  D shareholder  only  the first  time such
shareholder makes a redemption.
    

                              SHAREHOLDER SERVICES

   
    The Trust  offers a  number  of shareholder  services and  investment  plans
designed to facilitate investment in shares of the Fund. Full details as to each
of  such services, copies of the  various plans described below and instructions
as to how to participate in the various services or plans, or to change  options
with  respect thereto can  be obtained from  the Trust by  calling the telephone
number on the cover page hereof or from the Distributor or Merrill Lynch.
    

INVESTMENT ACCOUNT

   
    Each shareholder whose account  is maintained at the  Transfer Agent has  an
Investment  Account  and will  receive statements  at  least quarterly  from the
Transfer Agent. These  statements will  serve as  transaction confirmations  for
automatic investment purchases and the reinvestment of ordinary income dividends
and  long-term capital gain  distributions. These statements  will also show any
other activity in the account  since the preceding statement. Shareholders  will
receive separate transaction confirmations for each purchase or sale transaction
other  than  automatic investment  purchases and  the reinvestments  of ordinary
income dividends and  long-term capital gains  distributions. A shareholder  may
make additions to his Investment Account at any time by mailing a check directly
to  the Transfer  Agent. Shareholders may  also maintain  their accounts through
Merrill Lynch. Upon  the transfer  of shares out  of a  Merrill Lynch  brokerage
account,  an Investment Account  in the transferring  shareholder's name will be
opened  automatically   at   the  Transfer   Agent.   Shareholders   considering
transferring  their Class  A or  Class D  shares from  Merrill Lynch  to another
    

                                       30
<PAGE>
   
brokerage firm or  financial institution should  be aware that,  if the firm  to
which the Class A or Class D shares are to be transferred will not take delivery
of  shares of the Fund, a shareholder either  must redeem the Class A or Class D
shares (paying any applicable CDSC) so that the cash proceeds can be transferred
to the account at the new firm or such shareholder must continue to maintain  an
Investment  Account at the Transfer  Agent for those Class  A or Class D shares.
Shareholders interested in  transferring their Class  B or Class  C shares  from
Merrill  Lynch and who do not wish  to have an Investment Account maintained for
such shares  at the  Transfer Agent  may  request their  new brokerage  firm  to
maintain  such shares in an account registered in the name of the brokerage firm
for the benefit of the shareholder at the Transfer Agent.
    

EXCHANGE PRIVILEGE

   
    Shareholders of each class of shares of the Fund have an exchange  privilege
with  certain other MLAM-advised mutual funds.  There is currently no limitation
on the number of  times a shareholder may  exercise the exchange privilege.  The
exchange  privilege may be modified or terminated at any time in accordance with
the rules of the Commission.
    

   
    Under the  Merrill Lynch  Select Pricing  System, Class  A shareholders  may
exchange  Class A shares of the Fund for Class A shares of a second MLAM-advised
mutual fund if the shareholder  holds any Class A shares  of the second fund  in
his  account in which  the exchange is  made at the  time of the  exchange or is
otherwise eligible to purchase Class A shares of the second fund. If the Class A
shareholder wants to exchange Class A shares for shares of a second MLAM-advised
mutual fund, and the shareholder does not hold Class A shares of the second fund
in his account  at the time  of the exchange  and is not  otherwise eligible  to
acquire  Class A shares of the second fund, the shareholder will receive Class D
shares of the second fund as a result  of the exchange. Class D shares also  may
be exchanged for Class A shares of a second MLAM-advised mutual fund at any time
as long as, at the time of the exchange, the shareholder holds Class A shares of
the  second fund in  the account in which  the exchange is  made or is otherwise
eligible to purchase Class A shares of the second fund.
    

   
    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 will be exchangeable with shares of  the
same class of other MLAM-advised mutual funds.
    

   
    Shares  of the Fund 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 Fund. For  purposes
of  computing the  CDSC that  may be  payable upon  a disposition  of the shares
acquired in the exchange, the holding period for the previously owned shares  of
the  Fund is "tacked" to the holding period  of the newly acquired shares of the
other Fund.
    

   
    Class A, Class B, Class C and  Class D shares also 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
    

                                       31
<PAGE>
   
money market fund, however,  will not count toward  satisfaction of the  holding
period  requirement for reduction  of any CDSC  imposed on such  shares, if any,
and, with  respect to  Class B  shares, toward  satisfaction of  the  Conversion
Period.
    

   
    Class  B shareholders  of the  Fund exercising  the exchange  privilege will
continue to be subject to  the Fund's CDSC schedule  if such schedule is  higher
than  the CDSC schedule relating to the new Class B shares. In addition, Class B
shares of  the Fund  acquired through  use  of the  exchange privilege  will  be
subject  to the Fund's  CDSC schedule if  such schedule is  higher than the CDSC
schedule relating to  the Class B  shares of the  MLAM-advised mutual fund  from
which the exchange has been made.
    

   
    Exercise  of the exchange privilege is treated  as a sale for Federal income
tax purposes. For  further information,  see "Shareholder  Services --  Exchange
Privilege" in the Statement of Additional Information.
    

   
    The Fund's exchange privilege is modified with respect to purchases of Class
A  and  Class D  shares  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  a MLAM-advised mutual fund for Class A or Class D shares of the Fund will be
made solely on the basis  of the relative net asset  values of the shares  being
exchanged.  Therefore, there will not be a charge for any difference between the
sales charge previously paid on the shares of the other MLAM-advised mutual fund
and the sales charge  payable on the  shares of the Fund  being acquired in  the
exchange under the MFA program.
    

AUTOMATIC REINVESTMENT OF DIVIDENDS AND CAPITAL GAINS DISTRIBUTIONS

   
    All  dividends and capital gains  distributions are reinvested automatically
in full and fractional shares  of the Fund, without a  sales charge, at the  net
asset  value per share at the close of  business on the monthly payment date for
such dividends and  distributions. A  shareholder may  at any  time, by  written
notification  or by telephone  (1-800-MER-FUND) to the  Transfer Agent, elect to
have subsequent dividends or both dividends and capital gains distributions paid
in cash, rather than reinvested, in which event payment will be mailed  monthly.
Cash  payments can also be directly deposited to the shareholder's bank account.
No CDSC will  be imposed upon  redemption of shares  issued as a  result of  the
automatic reinvestment of dividends or capital gains distributions.
    

   
SYSTEMATIC WITHDRAWAL PLANS
    

   
    A  Class A or Class D shareholder may elect to receive systematic withdrawal
payments from  his Investment  Account  through automatic  payment by  check  or
through  automatic payment  by direct  deposit to his  bank account  on either a
monthly or quarterly basis. A  Class A or Class  D shareholder whose shares  are
held  within a CMA-R- or  CBA-R- Account may elect to  have shares redeemed on a
monthly, bimonthly, quarterly, semiannual or annual basis through the Systematic
Redemption Program, subject to certain conditions.
    

   
AUTOMATIC INVESTMENT PLANS
    
   
    Regular additions of Class A, Class B, Class C or Class D shares may be made
to an investor's Investment Account by prearranged charges of $50 or more to his
regular bank account. The Fund's  Automatic Investment Program is not  available
to shareholders whose shares are held in a brokerage
    

                                       32
<PAGE>
   
account  with  Merrill  Lynch.  Alternatively,  investors  who  maintain  CMA-R-
accounts may arrange  to have  periodic investments made  in the  Fund in  their
CMA-R- account or in certain related accounts in amounts of $100 or more through
the CMA-R- Automated Investment Program.
    

                             PORTFOLIO TRANSACTIONS

    The  Trust has no obligation to deal with  any dealer or group of dealers in
the execution of  transactions in  portfolio securities of  the Fund.  Municipal
Bonds and other securities in which the Fund invests are traded primarily in the
over-the-counter  market.  Where possible,  the  Trust deals  directly  with the
dealers  who  make  a  market  in  the  securities  involved  except  in   those
circumstances  where better prices and execution  are available elsewhere. It is
the policy of the Trust to obtain  the best net results in conducting  portfolio
transactions  for the Fund, taking into account such factors as price (including
the applicable dealer spread), the size, type and difficulty of the transactions
involved, the firm's general execution and operations facilities, and the firm's
risk in positioning the  securities involved and  the provision of  supplemental
investment  research  by  the  firm.  While  reasonably  competitive  spreads or
commissions are  sought, the  Fund will  not necessarily  be paying  the  lowest
spread or commission available. The sale of shares of the Fund may be taken into
consideration  as a  factor in  the selection of  brokers or  dealers to execute
portfolio transactions  for  the Fund.  The  portfolio securities  of  the  Fund
generally are traded on a net basis and normally do not involve either brokerage
commissions  or transfer taxes. The cost of portfolio securities transactions of
the Fund primarily  consists of dealer  or underwriter spreads.  Under the  1940
Act,  persons affiliated with the Trust, including Merrill Lynch, are prohibited
from dealing  with  the  Trust as  a  principal  in the  purchase  and  sale  of
securities  unless such trading is permitted by an exemptive order issued by the
Commission. The Trust has obtained an exemptive order permitting it to engage in
certain  principal  transactions  with  Merrill  Lynch  involving  high  quality
short-term municipal bonds subject to certain conditions. In addition, the Trust
may  not purchase securities, including Municipal Bonds, for the Fund during the
existence of  any underwriting  syndicate of  which Merrill  Lynch is  a  member
except pursuant to procedures approved by the Trustees of the Trust which comply
with  rules adopted by the Commission. Affiliated persons of the Trust may serve
as its broker  in over-the-counter  transactions conducted  for the  Fund on  an
agency basis only.

                            DISTRIBUTIONS AND TAXES

DISTRIBUTIONS

   
    The  net  investment  income of  the  Fund  is declared  as  dividends daily
following the normal close of trading on the New York Stock Exchange  (currently
4:00  P.M.) prior to the  determination of the net asset  value on that day. The
net investment income  of the Fund  for dividend purposes  consists of  interest
earned  on portfolio securities, less expenses,  in each case computed since the
most recent  determination  of  the  net asset  value.  Expenses  of  the  Fund,
including the management fees and the account maintenance and distribution fees,
are  accrued daily.  Dividends of net  investment income are  declared daily and
reinvested monthly in the form of  additional full and fractional shares of  the
Fund at net asset value as of the close of business on the "payment date" unless
the  shareholder elects  to receive such  dividends in cash.  Shares will accrue
dividends as long  as they  are issued and  outstanding. Shares  are issued  and
outstanding  from the settlement  date of a  purchase order to  the day prior to
settlement date of a redemption order.
    

                                       33
<PAGE>
   
    All net realized long-or short-term capital gains, if any, are declared  and
distributed  to the  Fund's shareholders  annually. Capital  gains distributions
will be  reinvested automatically  in shares  unless the  shareholder elects  to
receive such distributions in cash.
    

   
    The  per share dividends and  distributions on each class  of shares will be
reduced as  a result  of  any account  maintenance, distributions  and  transfer
agency fees applicable to that class with respect to the Class B shares.
    

    See  "Shareholder  Services"  for  information as  to  how  to  elect either
dividend reinvestment or cash payments. Portions of dividends and  distributions
which  are taxable to shareholders as described  below are subject to income tax
whether they are reinvested in shares of the Fund or received in cash.

TAXES

   
    The Trust  intends to  continue to  qualify  the Fund  for the  special  tax
treatment  afforded regulated  investment companies ("RICs")  under the Internal
Revenue Code  of 1986,  as amended  (the "Code").  If it  so qualifies,  in  any
taxable  year in which it distributes at least 90% of its taxable net income and
90%  of  its  tax-exempt  net  income  (see  below),  the  Fund  (but  not   its
shareholders)  will not be subject  to Federal income tax  to the extent that it
distributes its net investment income and net realized capital gains. The  Trust
intends to cause the Fund to distribute substantially all of its income.
    

   
    To the extent that the dividends distributed to the Fund's Class A, Class B,
Class C and Class D shareholders (together, the "shareholders") are derived from
interest  income exempt from  Federal income tax and  are properly designated as
"exempt-interest dividends"  by  the  Trust,  they will  be  excludable  from  a
shareholder's  gross  income for  Federal  income tax  purposes. Exempt-interest
dividends are  included, however,  in  determining the  portion,  if any,  of  a
person's  social security  and railroad  retirement benefits  subject to Federal
income taxes. The portion of  such exempt-interest dividends paid from  interest
received  by the Fund from Michigan Municipal Bonds also will be exempt from the
Michigan income and  single business tax.  In 1986, the  Michigan Department  of
Treasury  issued  a  Bulletin stating  that  holders of  interests  in regulated
investment companies who are subject to  the Michigan intangibles tax also  will
be  exempt from the tax to the extent that such a company's investment portfolio
consists of items such as Michigan Municipal Bonds. In addition, shares owned by
certain financial  institutions  or by  certain  other persons  subject  to  the
Michigan  single business tax  are not subject to  the Michigan intangibles tax.
Shareholders subject  to income  taxation  by states  other than  Michigan  will
realize  a lower after-tax  rate of return than  Michigan shareholders since the
dividends distributed  by  the  Fund  generally  will  not  be  exempt,  to  any
significant  degree, from income  taxation by such other  states. The Trust will
inform shareholders annually as to the portion of the Fund's distributions which
constitutes exempt-interest dividends and which portion is exempt from  Michigan
income  taxes. Interest  on indebtedness  incurred or  continued to  purchase or
carry Fund shares is not deductible for Federal income tax purposes or  Michigan
State  tax  purposes to  the extent  attributable to  exempt-interest dividends.
Persons who  may be  "substantial users"  (or "related  persons" of  substantial
users)  of  facilities  financed  by  industrial  development  bonds  or private
activity bonds  held  by the  Fund  should  consult their  tax  advisers  before
purchasing Fund shares.
    

   
    To the extent that the Fund's distributions are derived from interest on its
taxable  investments or from an excess of  net short-term capital gains over net
long-term capital losses ("ordinary  income dividends"), such distributions  are
considered taxable ordinary income for Federal and Michigan income tax purposes.
Such  distributions are  not eligible for  the dividends  received deduction for
corporations. Distributions, if
    

                                       34
<PAGE>
   
any, of net long-term capital gains from the sale of securities or from  certain
transactions  in futures  or options ("capital  gain dividends")  are taxable as
long-term capital  gains for  Federal  income tax  purposes, regardless  of  the
length of time the shareholder has owned Fund shares and for Michigan income tax
purposes  are treated as capital gains which are taxed as ordinary income. Under
the Revenue Reconciliation Act of 1993, all or a portion of the Fund's gain from
the sale or redemption of tax-exempt obligations purchased at a market  discount
will  be treated  as ordinary  income rather  than capital  gain. This  rule may
increase the  amount  of ordinary  income  dividends received  by  shareholders.
Distributions in excess of the Fund's earnings and profits will first reduce the
adjusted  tax basis of a  holder's shares and, after  such adjusted tax basis is
reduced to zero,  will constitute  capital gains  to such  holder (assuming  the
shares  are held  as a  capital asset). Any  loss upon  the sale  or exchange of
shares held for six months or less will be treated as long-term capital loss  to
the  extent  of  any capital  gain  dividends  received by  the  shareholder. In
addition, such loss  will be  disallowed to  the extent  of any  exempt-interest
dividends  received by the shareholder.  If the Fund pays  a dividend in January
which was declared in the previous October, November or December to shareholders
or record on a specified date in one of such months, then such dividend will  be
treated  for  tax  purposes  as being  paid  by  the Fund  and  received  by its
shareholders on December 31 of the year in which such dividend was declared.
    

   
    The  Code  subjects  interest  received  on  certain  otherwise   tax-exempt
securities  to an alternative minimum tax.  This alternative minimum tax applies
to interest received on  "private activity bonds" issued  after August 7,  1986.
Private  activity  bonds  are bonds  which,  although tax-exempt,  are  used for
purposes other than those  generally performed by  governmental units and  which
benefit  non-governmental entities (e.g., bonds  used for industrial development
or housing purposes). Income received on such bonds is classified as an item  of
"tax  preference,"  which  could  subject  investors  in  such  bonds, including
shareholders of the Fund, to an alternative minimum tax. The Fund will  purchase
such  "private activity bonds," and the Trust will report to shareholders within
60 days after the  Fund's taxable year-end the  portion of the Fund's  dividends
declared  during  the  year which  constitutes  an  item of  tax  preference for
alternative minimum tax  purposes. The Code  further provides that  corporations
are subject to an alternative minimum tax based, in part, on certain differences
between   taxable  income  as  adjusted  for   other  tax  preferences  and  the
corporation's  "adjusted  current  earnings"  (which  more  closely  reflect   a
corporation's  economic income). Because an exempt-interest dividend paid by the
Fund will be included in adjusted current earnings, a corporate shareholder  may
be  required to pay alternative minimum tax on exempt-interest dividends paid by
the Fund.
    

    The Revenue Reconciliation Act of 1993  has added new marginal tax  brackets
of  36% and 39.6% for  individuals and has created  a graduated structure of 26%
and 28%  for the  alternative minimum  tax applicable  to individual  taxpayers.
These  rate increases may affect an  individual investor's after-tax return from
an investment in the Fund as  compared with such investor's return from  taxable
investments.

   
    No gain or loss will be recognized by Class B shareholders on the conversion
of  their Class B shares into Class D shares. A shareholder's basis in the Class
D shares acquired will be  the same as such shareholder's  basis in the Class  B
shares  converted, and the  holding period of  the acquired Class  D shares will
include the holding period for the converted Class B shares.
    

   
    If a shareholder exercises an exchange privilege within 90 days of acquiring
the shares, then the loss such shareholder can recognize on the exchange will be
reduced   (or    the    gain    increased)   to    the    extent    the    sales
    

                                       35
<PAGE>
   
charge  paid to the  Fund reduces any  sales charge such  shareholder would have
owed upon purchase of the new shares  in the absence of the exchange  privilege.
Instead, such sales charge will be treated as an amount paid for the new shares.
    

   
    A  loss  realized on  a  sale or  exchange  of shares  of  the Fund  will be
disallowed if  other Fund  shares are  acquired (whether  through the  automatic
investment  of dividends or otherwise) within  a 61-day period beginning 30 days
before and ending 30  days after the  date that the shares  are disposed of.  In
such  a case, the basis  of the shares acquired will  be adjusted to reflect the
disallowed loss.
    

   
    Under certain provisions of the Code, some shareholders may be subject to  a
31%  withholding tax  on certain ordinary  income dividends and  on capital gain
dividends   and   redemption   payments   ("backup   withholding").   Generally,
shareholders  subject to backup withholding will  be those for whom no certified
taxpayer identification number is on file with the Trust or who, to the  Trust's
knowledge,  have furnished an incorrect number. When establishing an account, an
investor must certify under penalty of  perjury that such number is correct  and
that such investor is not otherwise subject to backup withholding.
    

    The  Code provides  that every  person required  to file  a tax  return must
include for information purposes  on such return  the amount of  exempt-interest
dividends  received from  all sources  (including the  Fund) during  the taxable
year.

    The foregoing  is  a  general  and abbreviated  summary  of  the  applicable
provisions  of the Code, Treasury regulations and Michigan tax laws presently in
effect. For the complete provisions, reference  should be made to the  pertinent
Code   sections,  the  Treasury  regulations   promulgated  thereunder  and  the
applicable Michigan personal  income, intangibles  and corporate  tax laws.  The
Code and the Treasury regulations, as well as the Michigan tax laws, are subject
to change by legislative, judicial or administrative action either prospectively
or retroactively.

    Shareholders   are  urged  to  consult  their  tax  advisers  regarding  the
availability of  any exemptions  from state  or local  taxes (other  than  those
imposed  by Michigan) and with specific  questions as to Federal, foreign, state
or local taxes.

                                PERFORMANCE DATA

   
    From time to  time the  Fund may include  its average  annual total  return,
yield   and  tax  equivalent  yield  for   various  specified  time  periods  in
advertisements or information furnished to present or prospective  shareholders.
Average  annual  total  return,  yield and  tax  equivalent  yield  are computed
separately for Class A, Class B, Class  C and Class D shares in accordance  with
formulas specified by the Commission.
    

   
    Average  annual total  return quotations for  the specified  periods will be
computed by finding the average annual compounded rates of return (based on  net
investment  income and  any realized and  unrealized capital gains  or losses on
portfolio investments over such  periods) that would  equate the initial  amount
invested  to the redeemable value of such  investment at the end of each period.
Average annual  total  return  will  be  computed  assuming  all  dividends  and
distributions  are reinvested and  taking into account  all applicable recurring
and nonrecurring expenses,  including any  CDSC that  would be  applicable to  a
complete redemption of the investment at the end of the specified period such as
in  the case of Class B  and Class C shares and  the maximum sales charge in the
case of Class A and Class D shares.  Dividends paid by the Fund with respect  to
all  shares to the extent any dividends are paid, will be calculated in the same
manner at the same time on
    

                                       36
<PAGE>
   
the same day and  will be in  the same amount,  except that account  maintenance
fees and distribution charges and any incremental transfer agency costs relating
to  each class of shares will be borne  exclusively by that Class. The Fund will
include performance  data  for  all  classes  of  shares  of  the  Fund  in  any
advertisement or information including performance data of the Fund.
    

   
    The  Fund also may quote total return and aggregate total return performance
data  for  various  specified  time  periods.  Such  data  will  be   calculated
substantially as described above, except that (1) the rates of return calculated
will  not  be average  annual rates,  but rather,  actual annual,  annualized or
aggregate rates of return and (2) the maximum applicable sales charges will  not
be  included with respect to annual  or annualized rates of return calculations.
Aside from  the impact  on the  performance data  calculations of  including  or
excluding  the  maximum applicable  sales charges,  actual annual  or annualized
total return data generally will be lower than average annual total return  data
since  the average annual  rates of return  reflect compounding, aggregate total
return data generally will be higher than average annual total return data since
the aggregate rates of return reflect compounding over a longer period of  time.
In advertisements distributed to investors whose purchases are subject to waiver
of  the CDSC in the case of Class B  and Class C shares or reduced sales charges
in the case of Class  A and Class D shares,  the performance data may take  into
account  the reduced,  and not the  maximum, sales  charge or may  not take into
account the CDSC and  therefore may reflect greater  total return since, due  to
the  reduced sales charges or waiver of the  CDSC, a lower amount of expenses is
deducted. See "Purchase  of Shares". The  Fund's total return  may be  expressed
either  as a percentage or as a dollar  amount in order to illustrate such total
return on a hypothetical $1,000 investment in the Fund at the beginning of  each
specified period.
    

   
    Yield  quotations will be computed based on  a 30-day period by dividing (a)
the net income based on the yield  of each security earned during the period  by
(b)  the average daily number of shares  outstanding during the period that were
entitled to receive dividends multiplied by the maximum offering price per share
on the last day of the period. Tax equivalent yield quotations will be  computed
by dividing (a) the part of the Fund's yield that is tax-exempt by (b) one minus
a  stated tax rate and (c) adding the result to that part, if any, of the Fund's
yield that is not  tax-exempt. The yield  for the 30-day  period ended July  31,
1994  was 5.22%  for Class A  shares and  4.93% for Class  B shares  and the tax
equivalent yield for the same period (based on a Federal income tax rate of 28%)
was 7.25% for Class  A shares and  6.85% for Class B  shares. The yield  without
voluntary  reimbursement for the 30-day period would have been 4.70% for Class A
shares and 4.39% for  Class B shares  with a tax equivalent  yield of 6.53%  for
Class A shares and 6.10% for Class B shares.
    

    Total   return  and  yield  figures  are  based  on  the  Fund's  historical
performance and  are not  intended to  indicate future  performance. The  Fund's
total  return and 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 gain or losses during the period. The  value
of  an investment  in the  Fund will  fluctuate and  an investor's  shares, when
redeemed, may be worth more or less than their original cost.

    On occasion,  the  Fund may  compare  its performance  to  performance  data
prepared  by Lipper  Analytical Services,  Inc., Morningstar  Publications, Inc.
("Morningstar"), and CDA  Investment Technology,  Inc. or to  data contained  in
publications  such as MONEY  MAGAZINE, U.S. NEWS &  WORLD REPORT, BUSINESS WEEK,
FORBES MAGAZINE and FORTUNE  MAGAZINE. From time to  time, the Fund may  include
the Fund's Morningstar risk-

                                       37

adjusted performance ratings in advertisements or supplemental sales literature.
As with other performance data, performance comparisons should not be considered
representative of the Fund's relative performance for any future period.

                             ADDITIONAL INFORMATION

DETERMINATION OF NET ASSET VALUE

   
    The  net asset value of the shares of  all classes of the Fund is determined
by the Manager once  daily as of 4:15  P.M., New York time,  on each day  during
which  the New York Stock Exchange is open  for trading. The net asset value per
share is computed by dividing the sum of the value of the securities held by the
Fund plus any cash or other assets minus all liabilities by the total number  of
shares  outstanding  at  such  time,  rounded  to  the  nearest  cent. Expenses,
including the  fees payable  to the  Manager and  the Distributor,  are  accrued
daily.
    

   
    The per share net asset value of the Class A shares generally will be higher
than  the per share net  asset value of shares  of the other classes, reflecting
the daily expense accruals of  the account maintenance, distribution and  higher
transfer  agency fees applicable with respect to  Class B and Class C shares and
the daily  expense accruals  of  the account  maintenance fees  applicable  with
respect  to Class D shares;  moreover, the per share net  asset value of Class D
shares generally will be higher  than the per share net  asset value of Class  B
and  Class C shares,  reflecting the daily expense  accruals of the distribution
and higher transfer agency fees applicable with  respect to Class B and Class  C
shares.  It is  expected, however,  that the  per share  net asset  value of the
classes will tend  to converge  immediately after  the payment  of dividends  or
distributions  which  will differ  by approximately  the  amount of  the expense
accrual differentials between the classes.
    

ORGANIZATION OF THE TRUST

   
    The Trust is an  unincorporated business trust organized  on August 2,  1985
under  the laws of Massachusetts. On October 1, 1987, the Trust changed its name
from "Merrill  Lynch  Multi-State Tax-Exempt  Series  Trust" to  "Merrill  Lynch
Multi-State  Municipal Bond  Series Trust"  and on  December 22,  1987 the Trust
changed its  name to  "Merrill Lynch  Multi-State Municipal  Series Trust".  The
Trust  is an open-end management investment company comprised of separate series
("Series"), each of which  is a separate portfolio  offering shares to  selected
groups of purchasers. Each of the Series is to be managed independently in order
to  provide to shareholders who are residents  of the state to which such Series
relates as high a level  of income exempt from  Federal, state and local  income
taxes  as is  consistent with  prudent investment  management. The  Trustees are
authorized to create  an unlimited number  of Series and,  with respect to  each
Series, to issue an unlimited number of full and fractional shares of beneficial
interest  of $.10  par value of  different classes. Shareholder  approval is not
required for the authorization  of additional Series or  classes of a Series  of
the  Trust. At the date  of this Prospectus, the shares  of the Fund are divided
into Class A shares, Class B, Class C and Class D shares. Both Class A, Class B,
Class C and Class D  shares represent interests in the  same assets of the  Fund
and  are identical  in all  respects except that  Class B,  Class C  and Class D
shares bear certain expenses related to the account maintenance associated  with
such shares, and Class B and Class C shares bear certain expenses related to the
distribution of such shares. Each class has exclusive voting rights with respect
to  matters  relating to  account maintenance  and distribution  expenditures as
applicable. See "Purchase of Shares". The  Trust has received an order from  the
Commission  permitting the issuance  and sale of  multiple classes of beneficial
interest. The Trustees of the Trust may classify and reclarify the shares of the
Trust into additional classes at a future date.
    

                                       38
<PAGE>
   
    Shareholders are entitled to one vote for each full share and to  fractional
votes  for fractional  shares held  in the election  of Trustees  (to the extent
hereinafter  provided)  and  on   other  matters  submitted   to  the  vote   of
shareholders.  There normally will be no meeting of shareholders for the purpose
of electing Trustees unless and until such  time as less than a majority of  the
Trustees  holding office  have been elected  by shareholders, at  which time the
Trustees then in office  will call a shareholders'  meeting for the election  of
Trustees.  Shareholders may, in accordance with  the terms of the Declaration of
Trust, cause a meeting of shareholders to  be held for the purpose of voting  on
the  removal of  Trustees. Also, the  Trust will  be required to  call a special
meeting of shareholders of a Series  in accordance with the requirements of  the
1940  Act to  seek approval  of new management  and advisory  arrangements, of a
material increase  in  distribution fees  or  of  a change  in  the  fundamental
policies, objectives or restrictions of a Series. Except as set forth above, the
Trustees  shall continue  to hold  office and  appoint successor  Trustees. Each
issued and outstanding share is entitled to participate equally in dividends and
distributions declared by the respective Series and in net assets of such Series
upon liquidation  or dissolution  remaining  after satisfaction  of  outstanding
liabilities except that, as noted above, the Class B, Class C and Class D shares
bear   certain  additional  expenses.  The  obligations  and  liabilities  of  a
particular Series are restricted to the assets of that Series and do not  extend
to  the assets of the  Trust generally. The shares  of each Series, when issued,
will be fully-paid and non-assessable by the Trust.
    

SHAREHOLDER REPORTS

    Only  one  copy   of  each  shareholder   report  and  certain   shareholder
communications  will be mailed to each  identified shareholder regardless of the
number of accounts  such shareholder  has. If  a shareholder  wishes to  receive
separate  copies of each report and  communication for each of the shareholder's
related accounts the shareholder should notify in writing:

   
       Financial Data Services, Inc.
       Attn: TAMFO
       P.O. Box 45289
       Jacksonville, FL 32232-5289
    

   
The written notification  should include  the shareholder's  name, address,  tax
identification  number and  Merrill Lynch,  Pierce, Fenner  & Smith Incorporated
and/or mutual fund  account numbers. If  you have any  questions regarding  this
matter  please call  your Merrill Lynch  financial consultant  or Financial Data
Services, Inc. at 800-637-3863.
    

SHAREHOLDER INQUIRIES

    Shareholder inquiries  may be  addressed  to the  Trust  at the  address  or
telephone number set forth on the cover page of this Prospectus.

    The  Declaration of  Trust establishing the  Trust, dated August  2, 1985, a
copy of which together  with all amendments thereto  (the "Declaration"), is  on
file  in  the office  of  the Secretary  of  the Commonwealth  of Massachusetts,
provides that the name "Merrill Lynch Multi-State Municipal Series Trust" refers
to the  Trustees under  the Declaration  collectively as  Trustees, but  not  as
individuals  or personally;  and no  Trustee, shareholder,  officer, employee or
agent of the Trust shall be held to any personal liability, nor shall resort  be
had  to such person's private property for the satisfaction of any obligation or
claim of the Trust, but the "Trust Property" only shall be liable.

                MERRILL LYNCH MULTI-STATE MUNICIPAL SERIES TRUST

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

    Merrill  Lynch  Michigan Municipal  Bond Fund  (the "Fund")  is a  series of
Merrill Lynch  Multi-State Municipal  Series Trust  (the "Trust"),  an  open-end
management  investment company organized as  a Massachusetts business trust. The
investment objective of the Fund is to provide shareholders with as high a level
of income  exempt  from  Federal  and  Michigan  personal  income  taxes  as  is
consistent  with prudent investment management. The  Fund invests primarily in a
non-diversified portfolio of long-term investment grade obligations the interest
on which is exempt from Federal and Michigan income taxes in the opinion of bond
counsel to the issuer  ("Michigan Municipal Bonds"). There  can be no  assurance
that the investment objective of the Fund will be realized.

   
    Pursuant  to the  Merrill Lynch Select  Pricing-SM- System,  the Fund offers
four classes of  shares, each  with a  different combination  of sales  charges,
ongoing  fees and  other features. The  Merrill Lynch  Select Pricing-SM- System
permits an investor to choose the method of purchasing shares that the  investor
believes is most beneficial given the amount of the purchase, the length of time

                       INVESTMENT OBJECTIVE AND POLICIES

   
    The investment objective of the Fund is to provide shareholders with as high
a  level of income exempt from Federal  and Michigan personal income taxes as is
consistent with prudent  investment management.  The Fund seeks  to achieve  its
objective  by investing primarily in a portfolio of long-term obligations issued
by or on behalf of the  State of Michigan, its political subdivisions,  agencies
and  instrumentalities  and obligations  of  other qualifying  issuers,  such as
issuers located in Puerto Rico, the Virgin Islands and Guam, which pay  interest
exempt,  in the opinion of bond counsel to the issuer, from Federal and Michigan
personal income taxes. Obligations exempt from Federal income taxes are referred
to herein as  "Municipal Bonds"  and obligations  exempt from  both Federal  and
Michigan  income taxes  are referred  to as  "Michigan Municipal  Bonds". Unless
otherwise indicated, references to  Municipal Bonds shall  be deemed to  include
Michigan  Municipal Bonds. The Fund anticipates that at all times, except during
temporary defensive periods, it will maintain  at least 65% of its total  assets
invested in Michigan Municipal Bonds. Reference is made to "Investment Objective
and Policies" in the Prospectus for a discussion of the investment objective and
policies of the Fund.
    

   
    Municipal  Bonds may include  general obligation bonds of  the State and its
political subdivisions,  revenue bonds  to  finance utility  systems,  highways,
bridges,  port and airport facilities,  colleges, hospitals, housing facilities,
etc., and industrial development bonds  or private activity bonds. The  interest
on  such  obligations may  bear a  fixed rate  or  be payable  at a  variable or
floating rate. The Municipal Bonds purchased by the Fund will be primarily  what
are commonly referred to as "investment grade" securities, which are obligations
rated  at  the time  of  purchase within  the  four highest  quality  ratings as
determined by either Moody's Investors Service, Inc. ("Moody's") (currently Aaa,
Aa, A and Baa), Standard &  Poor's Corporation ("Standard & Poor's")  (currently
AAA,  AA, A and BBB) or Fitch  Investors Service, Inc. ("Fitch") (currently AAA,
AA, A  and  BBB). If  unrated,  such securities  will  possess  creditworthiness
comparable,  in the opinion of  the manager of the  Fund, Fund Asset Management,
L.P. (the "Manager"), to other obligations in which the Fund may invest.
    

   
    The Fund ordinarily does not intend to realize investment income not  exempt
from  Federal and  Michigan income taxes.  However, to the  extent that suitable
Michigan Municipal Bonds are not available for investment by the Fund, the  Fund
may  purchase  Municipal  Bonds  issued  by  other  states,  their  agencies and
instrumentalities, the interest  income on which  is exempt, in  the opinion  of
bond counsel, from Federal, but not Michigan, taxation. The Fund also may invest
in securities not issued by or on behalf of a state or territory or by an agency
or instrumentality thereof, if the Fund nevertheless believes such securities to
be  exempt from Federal income taxation ("Non-Municipal Tax-Exempt Securities").
Non-Municipal Tax-Exempt  Securities  may  include securities  issued  by  other
investment  companies that invest in municipal bonds, to the extent permitted by
the Investment Company  Act of 1940,  as amended (the  "1940 Act") and  Michigan
law.
    

    Except  when  acceptable securities  are  unavailable as  determined  by the
Manager, the Fund, under normal circumstances,  will invest at least 65% of  its
total  assets in Michigan  Municipal Bonds. For temporary  periods or to provide
liquidity, the Fund  has the authority  to invest as  much as 35%  of its  total
assets  in tax-exempt or taxable money market obligations with a maturity of one
year or less (such short-term obligations being referred to herein as "Temporary
Investments"), except that taxable Temporary Investments shall not exceed 20% of
the Fund's net assets. The Fund at all  times will have at least 80% of its  net
assets  invested  in securities  exempt from  Federal income  taxation. However,
interest received on certain otherwise tax-exempt

                                       2
<PAGE>
securities which are classified  as "private activity  bonds" (in general  bonds
that benefit non-governmental entities) may be subject to an alternative minimum
tax.  The Fund may purchase such  private activity bonds. See "Distributions and
Taxes". In addition, the Fund reserves the right to invest temporarily a greater
portion of its assets in Temporary Investments for defensive purposes, when,  in
the judgment of the Manager, market conditions warrant. The investment objective
and  the  policies of  the  Fund set  forth  in this  paragraph  are fundamental
policies of the Fund which  may not be changed without  a vote of a majority  of
the  outstanding  shares of  the  Fund. The  Fund's  hedging strategies  are not
fundamental policies and may  be modified by the  Trustees of the Trust  without
the approval of the Fund's shareholders.

    Municipal  Bonds may  at times  be purchased or  sold on  a delayed delivery
basis or  a when-issued  basis.  These transactions  arise when  securities  are
purchased  or sold  by the Fund  with payment  and delivery taking  place in the
future, often a month or more after the purchase. The payment obligation and the
interest rate are each fixed at the  time the buyer enters into the  commitment.
The  Fund  will  make only  commitments  to  purchase such  securities  with the
intention of actually  acquiring the  securities, but  the Fund  may sell  these
securities  prior to the  settlement date if it  is deemed advisable. Purchasing
Municipal Bonds  on  a when-issued  basis  involves  the risk  that  the  yields
available  in the market  when the delivery  takes place actually  may be higher
than those obtained in the transaction itself; if yields so increase, the  value
of the when-issued obligations generally will decrease. The Fund will maintain a
separate  account at its custodian bank  consisting of cash, cash equivalents or
high-grade, liquid Municipal Bonds or  Temporary Investments (valued on a  daily
basis) equal at all times to the amount of the when-issued commitment.

   
    The  Fund may invest  in Municipal Bonds the  return on which  is based on a
particular index of value or interest rates. For example, the Fund may invest in
Municipal Bonds that pay interest based  on an index of Municipal Bond  interest
rates  or based  on the  value of  gold or  some other  commodity. The principal
amount payable upon maturity of certain Municipal Bonds also may be based on the
value of an  index. Also,  the Fund may  invest in  so-called "inverse  floating
obligations"  or "residual interest bonds" on which the interest rates typically
decline as  market rates  increase and  increase as  market rates  decline.  For
example,  to the extent the Fund invests  in these types of Municipal Bonds, the
Fund's return on such Municipal  Bonds will be subject  to risk with respect  to
the value of the particular index. 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 tax exempt securities increase  or decrease in response to
such changes. As a result, the  market values of such securities will  generally
be  more volatile than the market values of fixed-rate tax exempt securities. To
seek to limit the volatility of these securities, the Fund may purchase  inverse
floating  obligations with shorter term  maturities or which contain limitations
on the extent to  which the interest  rate may vary.  The Manager 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 15% of the Fund's net assets.
    

    The Fund may  purchase a  Municipal Bond  issuer's right  to call  all or  a
portion  of  such Municipal  Bond  for mandatory  tender  for purchase  (a "Call
Right"). A holder of a Call Right may exercise such right to require a mandatory
tender  for  the  purchase  of  related  Municipal  Bonds,  subject  to  certain
conditions. A

                                       3
<PAGE>
Call  Right that is not exercised prior to the maturity of the related Municipal
Bond will expire  without value. The  economic effect to  holding both the  Call
Right and the related Municipal Bond is identical to holding a Municipal Bond as
a  non-callable  security.  Certain  investments  in  such  obligations  may  be
illiquid. The  Fund  may  not  invest  in  such  illiquid  obligations  if  such
investments,  together with other illiquid investments,  would exceed 15% of the
Fund's net assets.

   
    The Fund may invest up to 20%  of its total assets in Municipal Bonds  which
are  rated below Baa  by Moody's or below  BBB by Standard &  Poor's or Fitch or
which, in the Manager's judgment, possess similar credit characteristics  ("high
yield  securities").  See  Appendix  II  --  "Ratings  of  Municipal  Bonds" for
additional  information  regarding  ratings  of  debt  securities.  The  Manager
considers  the ratings assigned by Standard & Poor's, Moody's or Fitch as one of
several factors in its independent credit analysis of issuers.
    

    High yield securities are considered by Standard & Poor's, Moody's and Fitch
to have varying degrees  of speculative characteristics. Consequently,  although
high  yield securities can be expected to provide higher yields, such securities
may be  subject  to  greater market  price  fluctuations  and risk  of  loss  of
principal than lower yielding, higher rated debt securities. Investments in high
yield  securities will be made  only when, in the  judgment of the Manager, such
securities provide attractive  total return  potential relative to  the risk  of
such  securities, as compared  to higher quality debt  securities. The Fund will
not invest in debt securities in the lowest rating categories (those rated CC or
lower by  Standard &  Poor's or  Fitch or  Ca or  lower by  Moody's) unless  the
Manager  believes that the  financial condition of the  issuer or the protection
afforded the particular securities is stronger than would otherwise be indicated
by such low ratings. The Fund does  not intend to purchase debt securities  that
are in default or which the Manager believes will be in default.

    Issuers  of high yield securities  may be highly leveraged  and may not have
available to them more  traditional methods of  financing. Therefore, the  risks
associated  with acquiring the securities of  such issuers generally are greater
than is the case with higher  rated securities. For example, during an  economic
downturn  or a sustained period of rising  interest rates, issuers of high yield
securities may be more likely to experience financial stress, especially if such
issuers are highly leveraged. During periods of economic recession, such issuers
may not have sufficient revenues to meet their interest payment obligations. The
issuer's ability to service its debt obligations also may be adversely  affected
by  specific issuer  developments, or  the issuer's  inability to  meet specific
projected business forecasts, or the unavailability of additional financing. The
risk of loss  due to  default by  the issuer  is significantly  greater for  the
holders  of high yield  securities because such securities  may be unsecured and
may be subordinated to other creditors of the issuer.

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

    The  Fund may  have difficulty  disposing of  certain high  yield securities
because there may be a thin trading market for such securities. Because not  all
dealers  maintain markets in all high  yield securities, there is no established
secondary market for  many of these  securities, and the  Fund anticipates  that
such  securities  could  be  sold  only  to  a  limited  number  of  dealers  or
institutional investors. To the extent that a secondary trading market for  high
yield  securities does  exist, it  generally is not  as liquid  as the secondary
market for higher rated securities. Reduced secondary market liquidity may  have
an  adverse  impact  on  market  price and  the  Fund's  ability  to  dispose of
particular issues  when necessary  to  meet the  Fund's  liquidity needs  or  in

                                       4
<PAGE>
response   to  a  specific  economic  event  such  as  a  deterioration  in  the
creditworthiness of the issuer. Reduced  secondary market liquidity for  certain
securities  also may  make it  more difficult  for the  Fund to  obtain accurate
market  quotations  for  purposes  of  valuing  the  Fund's  portfolio.   Market
quotations  generally are  available on many  high yield securities  only from a
limited number of dealers  and may not necessarily  represent firm bids of  such
dealers or prices for actual sales.

    It  is  expected that  a significant  portion of  the high  yield securities
acquired by the Fund will be purchased upon issuance, which may involve  special
risks  because the securities so acquired are  new issues. In such instances the
Fund may  be  a  substantial purchaser  of  the  issue and  therefore  have  the
opportunity  to participate in  structuring the terms  of the offering. Although
this may enable  the Fund  to seek  to protect  itself against  certain of  such
risks, the considerations discussed herein would nevertheless remain applicable.

    Adverse  publicity  and  investor perceptions,  which  may not  be  based on
fundamental analysis, also may  decrease the value and  liquidity of high  yield
securities,  particularly in a thinly traded market. Factors adversely affecting
the market value  of high yield  securities are likely  to affect adversely  the
Fund's  net asset value. In addition, the  Fund may incur additional expenses to
the extent that it is  required to seek recovery upon  a default on a  portfolio
holding or participate in the restructuring of the obligation.

            DESCRIPTION OF MUNICIPAL BONDS AND TEMPORARY INVESTMENTS

   
    Set  forth  below is  a  description of  the  Municipal Bonds  and Temporary
Investments in which the  Fund may invest. Information  with respect to  ratings
assigned  to tax-exempt obligations which the Fund  may purchase is set forth in
Appendix II to this Statement of Additional Information.
    

DESCRIPTION OF MUNICIPAL BONDS

    Municipal Bonds include debt obligations issued to obtain funds for  various
public  purposes, including construction  of a wide  range of public facilities,
refunding of outstanding obligations and  obtaining funds for general  operating
expenses  and loans  to other public  institutions and  facilities. In addition,
certain types of industrial development bonds or  are issued by or on behalf  of
public  authorities to finance  various privately owned  or operated facilities,
including pollution control facilities. Such obligations are included within the
term Municipal Bonds if  the interest paid  thereon is, in  the opinion of  bond
counsel,  excluded from gross income for Federal income tax purposes and, in the
case of Michigan Municipal  Bonds, exempt from  Michigan personal income  taxes.
Other  types  of industrial  development bonds  or  private activity  bonds, the
proceeds of which  are used for  the construction, equipment  or improvement  of
privately operated industrial or commercial facilities, may constitute Municipal
Bonds,  although the current  Federal tax laws  place substantial limitations on
the size of such issues.

   
    The  two  principal   classifications  of  Municipal   Bonds  are   "general
obligation"  bonds and "revenue" bonds. General  obligation bonds are secured by
the issuer's  pledge  of faith,  credit  and taxing  power  for the  payment  of
principal and interest. Revenue bonds are payable only from the revenues derived
from  a particular facility or  class of facilities or,  in some cases, from the
proceeds of a special or  limited tax or other  specific revenue source such  as
from  the user of the facility  being financed. Industrial development bonds are
in most cases revenue bonds  and generally do not  constitute the pledge of  the
credit  or taxing power of  the issuer of such  bonds. Generally, the payment of
the principal of and interest on such bonds depends solely on the ability of the
user of the facility financed by the bonds to meet its financial obligations and
the pledge, if any, of  real and personal property  so financed as security  for
such payment, unless a line of credit, bond
    

                                       5
<PAGE>
insurance  or other security  is furnished. The  Fund also may  invest in "moral
obligation"  bonds,  which  are  normally  issued  by  special  purpose   public
authorities.  If  an issuer  of moral  obligation  bonds is  unable to  meet its
obligations, the repayment of such bonds  becomes a moral commitment, but not  a
legal obligation, of the state or municipality in question.

    Also   included  within  the   general  category  of   Municipal  Bonds  are
participation certificates  issued  by  government authorities  or  entities  to
finance  the acquisition or  construction of equipment,  land and/or facilities.
The certificates represent  participations in a  lease, an installment  purchase
contract or a conditional sales contract (hereinafter collectively called "lease
obligations")  relating to  such equipment,  land or  facilities. Although lease
obligations do not constitute  general obligations of the  issuer for which  the
issuer's  unlimited taxing  power is pledged,  a lease  obligation is frequently
backed by the issuer's covenant to budget for, appropriate and make the payments
due under  the  lease obligation.  However,  certain lease  obligations  contain
"non-appropriation"  clauses which provide that the  issuer has no obligation to
make lease or  installment purchase  payments in  future years  unless money  is
appropriated  for such purpose  on a yearly  basis. Although "non-appropriation"
lease obligations  are  secured  by  the leased  property,  disposition  of  the
property  in the  event of foreclosure  might prove  difficult. These securities
represent a relatively  new type  of financing that  has not  yet developed  the
depth  of marketability  associated with  more conventional  securities. Certain
investments in lease  obligations may be  illiquid. The Fund  may not invest  in
illiquid lease obligations if such investments, together with all other illiquid
investments,  would exceed 15% of the Fund's  net assets. The Fund may, however,
invest without regard to such limitation in lease obligations which the Manager,
pursuant to the guidelines which have been adopted by the Board of Trustees  and
subject  to the supervision of  the Board of Trustees,  determines to be liquid.
The Manager will deem lease obligations liquid if they are publicly offered  and
have  received an investment grade rating of Baa or better by Moody's, or BBB or
better by Standard & Poor's or Fitch. Unrated lease obligations, or those  rated
below investment grade, will be considered liquid if the obligations come to the
market  through an  underwritten public  offering and  at least  two dealers are
willing to give competitive bids. In reference to the latter, the Manager  must,
among  other  things,  also  review  the  creditworthiness  of  the municipality
obligated to make payment under the lease obligation and make certain  specified
determinations  based on  such factors  as the existence  of a  rating or credit
enhancement such  as  insurance, the  frequency  of  trades or  quotes  for  the
obligation and the willingness of dealers to make a market in the obligation.

   
    Yields  on Municipal Bonds are dependent  on a variety of factors, including
the general condition of the money market and of the municipal bond market,  the
size  of  a particular  offering,  the financial  condition  of the  issuer, the
general conditions of the Municipal Bond market, the maturity of the obligation,
and the rating of the issue. The  ability of the Fund to achieve its  investment
objective  also is  dependent on  the continuing ability  of the  issuers of the
bonds in which the  Fund invests to  meet their obligations  for the payment  of
interest  and principal when due. There are  variations in the risks involved in
holding Municipal Bonds,  both within  a particular  classification and  between
classifications,  depending  on  numerous factors.  Furthermore,  the  rights of
owners of Municipal Bonds  and the obligations of  the issuer of such  Municipal
Bonds  may be subject to applicable  bankruptcy, insolvency and similar laws and
court decisions affecting the rights of creditors generally.
    

DESCRIPTION OF TEMPORARY INVESTMENTS

    The Fund may invest in short-term tax-free and taxable securities subject to
the limitations  set  forth  under  "Investment  Objective  and  Policies".  The
tax-exempt money market securities may include municipal

                                       6
<PAGE>
notes,  municipal commercial paper,  municipal bonds with  remaining maturity of
less than  one year,  variable  rate demand  notes and  participations  therein.
Municipal  notes  include tax  anticipation notes,  bond anticipation  notes and
grant anticipation notes. Anticipation  notes are sold  as interim financing  in
anticipation  of  tax  collection,  bond  sales,  government  grants  or revenue
receipts. Municipal commercial paper  refers to short-term unsecured  promissory
notes  generally issued  to finance short-term  credit needs.  The taxable money
market securities in which the Fund may invest as Temporary Investments  consist
of  U.S. Government securities, U.S. Government agency securities, domestic bank
or  savings  institution  certificates  of  deposit  and  bankers'  acceptances,
short-term  corporate debt securities  such as commercial  paper, and repurchase
agreements. These  Temporary Investments  must  have a  stated maturity  not  in
excess of one year from the date of purchase.

    Variable  rate demand obligations ("VRDOs") are tax-exempt obligations which
contain  a  floating  or  variable  interest  rate  adjustment  formula  and  an
unconditional  right of  demand on  the part  of the  holder thereof  to receive
payment of  the unpaid  principal balance  plus accrued  interest upon  a  short
notice  period not to exceed seven days. There is, however, the possibility that
because of default or insolvency the  demand feature of VRDOs and  Participating
VRDOs, described below, may not be honored. The interest rates are adjustable at
intervals  (ranging from daily to up to one year) to some prevailing market rate
for similar investments,  such adjustment formula  being calculated to  maintain
the  market value of the VRDO at approximately the par value of the VRDOs on the
adjustment date. The adjustments  typically are based upon  the prime rate of  a
bank  or some  other appropriate  interest rate  adjustment index.  The Fund may
invest in all  types of tax-exempt  instruments currently outstanding  or to  be
issued in the future which satisfy the short-term maturity and quality standards
of the Fund.

    The  Fund also may  invest in VRDOs  in the form  of participation interests
("Participating VRDOs")  in  variable  rate tax-exempt  obligations  held  by  a
financial  institution, typically a commercial bank. Participating VRDOs provide
the Fund with  a specified  undivided interest (up  to 100%)  of the  underlying
obligation  and the right to demand payment of the unpaid principal balance plus
accrued interest on the Participating VRDOs from the financial institution  upon
a  specified number of  days' notice, not  to exceed seven  days. In addition, a
Participating VRDO is backed by an  irrevocable letter of credit or guaranty  of
the  financial institution.  The Fund  would have  an undivided  interest in the
underlying obligation and thus  participate on the same  basis as the  financial
institution  in such obligation except  that the financial institution typically
retains fees  out of  the interest  paid  on the  obligation for  servicing  the
obligation,   providing  the  letter  of   credit  and  issuing  the  repurchase
commitment. The Fund has  been advised by  its counsel that  the Fund should  be
entitled  to treat the  income received on Participating  VRDOs as interest from
tax-exempt obligations.

    VRDOs that contain an  unconditional right of demand  to receive payment  of
the  unpaid principal balance plus accrued interest on a notice period exceeding
seven days may be deemed to be illiquid securities. A VRDO with a demand  notice
period  exceeding seven days will therefore be subject to the Fund's restriction
on illiquid investments unless,  in the judgment of  the Trustees, such VRDO  is
liquid.  The Trustees may adopt guidelines and delegate to the Manager the daily
function of determining and  monitoring liquidity of  such VRDOs. The  Trustees,
however, will retain sufficient oversight and will be ultimately responsible for
such determination.

    The  Trust has  established the  following standards  with respect  to money
market securities  and  VRDOs  in  which  the  Fund  invests.  Commercial  paper
investments    at    the    time    of   purchase    must    be    rated   "A-1"

                                       7
<PAGE>
through "A-3" by Standard  & Poor's, "Prime-1" through  "Prime-3" by Moody's  or
"F-1"  through "F-3" by  Fitch or, if  not rated, issued  by companies having an
outstanding debt  issue  rated at  least  "A" by  Standard  & Poor's,  Fitch  or
Moody's.  Investments  in  corporate  bonds  and  debentures  (which  must  have
maturities at the date  of purchase of one  year or less) must  be rated at  the
time  of purchase at least "A" by Standard & Poor's, Moody's or Fitch. Notes and
VRDOs at  the  time of  purchase  must be  rated  SP-1/A-1 through  SP-2/A-3  by
Standard  & Poor's, MIG-l/VMIG-1 through MIG-4/VMIG-4  by Moody's or F-1 through
F-3 by Fitch. Temporary Investments, if not rated, must be of comparable quality
to securities  rated  in the  above  rating categories  in  the opinion  of  the
Manager.  The Fund may not invest in any security issued by a commercial bank or
a savings institution unless the bank or institution is organized and  operating
in  the United States, has total assets of at least one billion dollars and is a
member of the Federal Deposit Insurance Corporation ("FDIC"), except that up  to
10%  of  total  assets may  be  invested  in certificates  of  deposit  of small
institutions if such certificates are insured fully by the FDIC.

   
REPURCHASE AGREEMENTS
    

   
    The Fund  may  invest  in  securities  pursuant  to  repurchase  agreements.
Repurchase agreements may be entered into only with a member bank of the Federal
Reserve  System or primary dealer in  U.S. Government securities or an affiliate
thereof. Under  such  agreements, the  seller  agrees, upon  entering  into  the
contract,  to repurchase the security at a  mutually agreed upon time and price,
thereby determining the yield during the term of the agreement. This results  in
a fixed rate of return insulated from market fluctuations during such period. In
the  case of repurchase agreements, the prices at which the trades are conducted
do not reflect accrued interest  on the underlying obligations. Such  agreements
usually  cover short periods, such as  under one week. Repurchase agreements may
be construed to be collateralized loans  by the purchaser to the seller  secured
by  the securities  transferred to  the purchaser. In  the case  of a repurchase
agreement, the Fund will require the seller to provide additional collateral  if
the  market value of the securities falls below the repurchase price at any time
during the term  of the repurchase  agreement. In  the event of  default by  the
seller  under a repurchase agreement construed  to be a collateralized loan, the
underlying securities are not owned by  the Fund but only constitute  collateral
for the seller's obligation to pay the repurchase price. Therefore, the Fund may
suffer  time delays and  incur costs or  possible losses in  connection with the
disposition of the collateral. In the event of a default under such a repurchase
agreement or under  a purchase  and sale  contract, instead  of the  contractual
fixed  rate of return, the rate of return to the Fund will depend on intervening
fluctuations of the market  value of such security  and the accrued interest  on
the  security. In such event, the Fund  would have rights against the seller for
breach of contract with respect to  any losses arising from market  fluctuations
following  the failure  of the  seller to  perform. The  Fund may  not invest in
repurchase agreements  maturing in  more than  seven days  if such  investments,
together with all other illiquid investments, would exceed 15% of the Fund's net
assets.
    

   
    In  general,  for Federal  income  tax purposes,  repurchase  agreements are
treated as collateralized  loans secured  by the  securities "sold".  Therefore,
amounts earned under such agreements will not be considered tax-exempt interest.
However,  it  is likely  that income  from  such arrangements  also will  not be

    Reference is made  to the discussion  concerning futures transactions  under
"Investment  Objective  and  Policies" in  the  Prospectus. Set  forth  below is
additional information concerning these transactions.

    As described in  the Prospectus,  the Fund  may purchase  and sell  exchange
traded  financial futures contracts ("financial futures contracts") to hedge its
portfolio of Municipal Bonds  against declines in the  value of such  securities
and  to hedge against  increases in the  cost of securities  the Fund intends to
purchase. However, any transactions involving financial futures or options  (and
puts  and  calls associated  therewith) will  be in  accordance with  the Fund's
investment policies and limitations. See  "Investment Objective and Policies  --
Investment Restrictions" in the Prospectus. To hedge its portfolio, the Fund may
take  an  investment position  in  a futures  contract  which will  move  in the
opposite direction from the  portfolio position being  hedged. While the  Fund's
use  of hedging strategies is intended  to moderate capital changes in portfolio
holdings and  thereby reduce  the volatility  of  the net  asset value  of  Fund
shares,  the Fund anticipates that its net asset value will fluctuate. Set forth
below is information concerning futures transactions.
    

    DESCRIPTION OF FUTURES CONTRACTS. A futures contract is an agreement between
two parties to buy and sell a security, or in the case of an index-based futures
contract, to make and accept a cash settlement for a set price on a future date.
A majority of transactions in futures  contracts, however, do not result in  the
actual delivery of the underlying instrument or cash settlement, but are settled
through  liquidation, i.e., by entering  into an offsetting transaction. Futures
contracts have  been designed  by boards  of trade  which have  been  designated
"contracts markets" by the Commodity Futures Trading Commission ("CFTC").

    The purchase or sale of a futures contract differs from the purchase or sale
of  a security  in that  no price or  premium is  paid or  received. Instead, an
amount of cash or securities acceptable to the broker and the relevant  contract
market,  which varies, but is generally about 5% of the contract amount, must be
deposited with  the  broker.  This  amount is  known  as  "initial  margin"  and
represents a "good faith" deposit assuring the performance of both the purchaser
and  seller  under the  futures contract.  Subsequent payments  to and  from the
broker, called "variation margin", are required to  be made on a daily basis  as
the price of the futures contract fluctuates making the long and short positions
in  the futures contract more or less valuable,  a process known as "mark to the
market". At any time prior to the  settlement date of the futures contract,  the
position  may be closed out by taking an opposite position which will operate to
terminate the  position  in  the  futures contract.  A  final  determination  of
variation  margin is  then made, additional  cash is  required to be  paid to or
released by the broker, and the purchaser realizes a loss or gain. In  addition,
a nominal commission is paid on each completed sale transaction.

    The  Fund  may deal  in  financial futures  contracts  based on  a long-term
municipal bond index  developed by the  Chicago Board of  Trade ("CBT") and  The
Bond  Buyer (the "Municipal Bond Index").  The Municipal Bond Index is comprised
of 40  tax-exempt municipal  revenue and  general obligations  bonds. Each  bond
included  in the Municipal  Bond Index must be  rated A or  higher by Moody's or
Standard & Poor's and must have a remaining maturity of 19 years or more.  Twice
a  month new issues satisfying the eligibility requirements are added to, and an
equal number of old issues are deleted from, the Municipal Bond Index. The value
of the Municipal Bond Index  is computed daily according  to a formula based  on
the  price  of  each bond  in  the Municipal  Bond  Index, as  evaluated  by six
dealer-to-dealer brokers.

    The Municipal Bond Index  futures contract is traded  only on the CBT.  Like
other  contract  markets, the  CBT assures  performance under  futures contracts
through a clearing corporation, a nonprofit organization managed by the exchange
membership which also is responsible  for handling daily accounting of  deposits
or withdrawals of margin.

    As  described in  the Prospectus, the  Fund may purchase  and sell financial
futures contracts  on U.S.  Government  securities as  a hedge  against  adverse
changes  in interest rates  as described below. With  respect to U.S. Government
securities, currently there are financial  futures contracts based on  long-term
U.S.  Treasury bonds,  Treasury notes, Government  National Mortgage Association
("GNMA") Certificates and three-month U.S. Treasury bills. The Fund may purchase
and write  call  and  put  options  on  futures  contracts  on  U.S.  Government
securities in connection with its hedging strategies.

    Subject  to policies adopted  by the Trustees,  the Fund also  may engage in
other  futures  contracts  transactions  such  as  futures  contracts  on  other
municipal  bond  indices  which may  become  available  if the  Manager  and the
Trustees should  determine  that  there is  normally  a  sufficient  correlation
between  the prices of such  futures contracts and the  Municipal Bonds in which
the Fund invests to make such hedging appropriate.

    FUTURES STRATEGIES. The Fund  may sell a  financial futures contract  (i.e.,
assume  a  short position)  in anticipation  of a  decline in  the value  of its
investments in Municipal Bonds resulting from  an increase in interest rates  or
otherwise.  The risk of decline could be  reduced without employing futures as a
hedge by selling  such Municipal Bonds  and either reinvesting  the proceeds  in
securities  with shorter maturities or by holding assets in cash. This strategy,
however, entails increased transaction costs in  the form of dealer spreads  and
typically would reduce the average yield of the Fund's portfolio securities as a
result  of the shortening of maturities.  The sale of futures contracts provides
an alternative means of hedging against declines in the value of its investments
in Municipal Bonds. As such values decline, the value of the Fund's positions in
the futures contracts will tend to increase, thus offsetting all or a portion of
the depreciation in the  market value of the  Fund's Municipal Bond  investments
which are being hedged. While the Fund will incur commission expenses in selling
and closing out futures positions, commissions on futures transactions are lower
than  transaction costs incurred in the purchase and sale of Municipal Bonds. In
addition, the  ability  of the  Fund  to  trade in  the  standardized  contracts
available  in the futures markets may  offer a more effective defensive position
than a program to reduce the average maturity of the portfolio securities due to
the unique and varied credit and technical characteristics of the municipal debt
instruments available to the Fund. Employing futures as a hedge also may  permit
the  Fund  to assume  a  defensive posture  without  reducing the  yield  on its
investments beyond any amounts required to engage in futures trading.

    When the Fund  intends to purchase  Municipal Bonds, the  Fund may  purchase
futures  contracts as a hedge against any increase in the cost of such Municipal
Bonds, resulting from an increase in interest rates or otherwise, that may occur
before such purchases  can be  effected. Subject  to the  degree of  correlation
between  the Municipal Bonds and the  futures contracts, subsequent increases in
the cost of Municipal Bonds should be reflected in the value of the futures held
by the  Fund.  As such  purchases  are made,  an  equivalent amount  of  futures
contracts  will be  closed out. Due  to changing market  conditions and interest
rate forecasts,  however,  a  futures  position  may  be  terminated  without  a
corresponding purchase of portfolio securities.

    CALL  OPTIONS  ON FUTURES  CONTRACTS. The  Fund also  may purchase  and sell
exchange traded call  and put  options on  financial futures  contracts on  U.S.
Government  securities. The purchase of  a call option on  a futures contract is
analogous to the purchase of a call option on an individual security.  Depending
on the pricing of the option compared to either the futures contract on which it
is based, or on the price of the

                                       10
<PAGE>
underlying  debt securities, it may  or may not be  less risky than ownership of
the futures  contract or  underlying debt  securities. Like  the purchase  of  a
futures  contract, the Fund will purchase a call option on a futures contract to
hedge against a market advance when the Fund is not fully invested.

    The writing of  a call option  on a futures  contract constitutes a  partial
hedge  against declining  prices of  the securities  which are  deliverable upon
exercise of the futures  contract. If the futures  price at expiration is  below
the  exercise price, the Fund will retain  the full amount of the option premium
which provides a partial hedge against any decline that may have occurred in the
Fund's portfolio holdings.

    PUT OPTIONS  ON FUTURES  CONTRACTS. The  purchase of  options on  a  futures
contract  is analogous  to the purchase  of protective put  options on portfolio
securities. The Fund will purchase put options on futures contracts to hedge the
Fund's portfolio against the risk of rising interest rates.

    The writing of  a put  option on a  futures contract  constitutes a  partial
hedge  against increasing  prices of the  securities which  are deliverable upon
exercise of the futures contract. If  the futures price at expiration is  higher
than  the exercise  price, the Fund  will retain  the full amount  of the option
premium which provides  a partial  hedge against any  increase in  the price  of
Municipal Bonds which the Fund intends to purchase.

    The writer of an option on a futures contract is required to deposit initial
and  variation margin  pursuant to requirements  similar to  those applicable to
futures contracts.  Premiums received  from the  writing of  an option  will  be
included  in initial  margin. The  writing of  an option  on a  futures contract
involves risks similar to those relating to futures contracts.
                              -------------------

   
    The Trust has received an order from the Securities and Exchange  Commission
("Commission")  exempting it  from the provisions  of Section  17(f) and Section
18(f) of the 1940 Act  in connection with its  strategy of investing in  futures
contracts.  Section 17(f) relates to the  custody of securities and other assets
of an investment  company and  may be  deemed to  prohibit certain  arrangements
between  the Trust and commodities brokers with respect to initial and variation
margin. Section 18(f) of the 1940  Act prohibits an open-end investment  company
such as the Trust from issuing a "senior security" other than a borrowing from a
bank.  The staff  of the  Commission has  in the  past indicated  that a futures
contract may be a "senior security" under the 1940 Act.
    

    RESTRICTIONS ON  USE  OF  FUTURES  TRANSACTIONS.  Regulations  of  the  CFTC
applicable  to  the Fund  require that  all of  the Fund's  futures transactions
constitute bona fide hedging  transactions and that the  Fund purchase and  sell
futures  contracts and options  thereon (i) for bona  fide hedging purposes, and
(ii) for  non-hedging purposes,  if the  aggregate initial  margin and  premiums
required to establish positions in such contracts and options does not exceed 5%
of  the  liquidation value  of  the Fund's  portfolio  assets after  taking into
account unrealized  profits and  unrealized  losses on  any such  contracts  and
options.   (However,  the  Fund  intends  to   engage  in  options  and  futures
transactions only for hedging purposes.) Margin deposits may consist of cash  or
securities acceptable to the broker and the relevant contract market.

    When  the Fund  purchases futures  contracts or  a call  option with respect
thereto or writes a put  option on a futures contract,  an amount of cash,  cash
equivalents or short-term, high-grade, fixed income securities will be deposited
in  a  segregated  account with  the  Fund's  custodian so  that  the  amount so
segregated, plus the amount of initial and variation margin held in the  account
of its broker, equals the market value of the futures contract, thereby ensuring
that the use of such futures is unleveraged.

<PAGE>
    RISK  FACTORS  IN FUTURES  TRANSACTIONS AND  OPTIONS. Investment  in futures
contracts involves the risk  of imperfect correlation  between movements in  the
price  of the futures contract  and the price of  the security being hedged. The
hedge will not be  fully effective when there  is imperfect correlation  between
the  movements in the prices  of two financial instruments.  For example, if the
price of the futures contract moves more than the price of the hedged  security,
the  Fund will experience either a loss or gain on the futures contract which is
not offset completely  by movements in  the price of  the hedged securities.  To
compensate  for imperfect  correlations, the Fund  may purchase  or sell futures
contracts in  a  greater  dollar  amount  than  the  hedged  securities  if  the
volatility  of the hedged securities is historically greater than the volatility
of the  futures contracts.  Conversely,  the Fund  may  purchase or  sell  fewer
futures  contracts if the  volatility of the  price of the  hedged securities is
historically less than that of the futures contracts.

   
    The particular municipal bonds comprising the index underlying the Municipal
Bond Index financial futures contract may vary from the bonds held by the  Fund.
As  a result, the  Fund's ability to hedge  effectively all or  a portion of the
value of its Municipal Bonds through the use of such financial futures contracts
will depend  in  part on  the  degree to  which  price movements  in  the  index
underlying  the financial futures contract correlate with the price movements of
the Municipal  Bonds  held by  the  Fund. The  correlation  may be  affected  by
disparities  in the average maturity, ratings,  geographical mix or structure of
the Fund's investments as compared to those comprising the Municipal Bond Index,
and general economic or political factors. In addition, the correlation  between
movements in the value of the Municipal Bond Index may be subject to change over
time  as additions  to and  deletions from  the Municipal  Bond Index  alter its
structure.  The  correlation  between  futures  contracts  on  U.S.   Government
securities and the Municipal Bonds held by the Fund may be adversely affected by
similar  factors and the risk of  imperfect correlation between movements in the
prices of such futures contracts and the  prices of the Municipal Bonds held  by
the Fund may be greater.
    

    The  Fund expects to liquidate a majority of the futures contracts it enters
into through offsetting  transactions on the  applicable contract market.  There
can  be no assurance, however, that a liquid secondary market will exist for any
particular futures contract at any specific  time. Thus, it may not be  possible
to  close out a futures  position. In the event  of adverse price movements, the
Fund would continue  to be  required to make  daily cash  payments of  variation
margin.  In  such situations,  if  the Fund  has  insufficient cash,  it  may be
required  to  sell   portfolio  securities  to   meet  daily  variation   margin
requirements at a time when it may be disadvantageous to do so. The inability to
close  out futures  positions also  could have an  adverse impact  on the Fund's
ability to hedge effectively its investments  in Municipal Bonds. The Fund  will
enter  into a futures  position only if,  in the judgment  of the Manager, there
appears to be an actively traded secondary market for such futures contracts.

    The successful  use of  transactions  in futures  and related  options  also
depends  on the ability of  the Manager to forecast  correctly the direction and
extent of  interest rate  movements within  a given  time frame.  To the  extent
interest  rates remain stable during  the period in which  a futures contract or
option is held by the  Fund or such rates move  in a direction opposite to  that
anticipated, the Fund may realize a loss on the hedging transaction which is not
fully  or partially offset by an increase  in the value of portfolio securities.
As a result, the Fund's total return for such period may be less than if it  had
not engaged in the hedging transaction.

    Because  of low  initial margin  deposits made on  the opening  of a futures
position, futures  transactions  involve  substantial  leverage.  As  a  result,
relatively   small  movements  in  the  price   of  the  futures  contracts  can

                                       12
<PAGE>
result in substantial unrealized gains or  losses. Because the Fund will  engage
in  the  purchase and  sale of  futures contracts  solely for  hedging purposes,
however, any  losses incurred  in connection  therewith should,  if the  hedging
strategy  is successful, be offset in whole or in part by increases in the value
of securities held by the Fund or decreases in the price of securities the  Fund
intends to acquire.

    The amount of risk the Fund assumes when it purchases an option on a futures
contract  is the premium paid for the  option plus related transaction costs. In
addition to the correlation risks discussed above, the purchase of an option  on
a  futures  contract also  entails the  risk that  changes in  the value  of the
underlying futures contract  will not  be reflected fully  in the  value of  the
option purchased.

    Municipal  Bond Index futures contracts have only recently been approved for
trading and therefore have little trading  history. It is possible that  trading
in  such  futures contracts  will  be less  liquid  than that  in  other futures
contracts. The trading of  futures contracts also is  subject to certain  market
risks,  such  as  inadequate trading  activity,  which  could at  times  make it
difficult or impossible to liquidate existing positions.

                            INVESTMENT RESTRICTIONS

   
    CURRENT INVESTMENT RESTRICTIONS. In addition to the investment  restrictions
set  forth the Prospectus,  the Trust has  adopted a number  of restrictions and
policies relating to the investment of its assets and its activities, which  are
fundamental  policies and may not be changed without the approval of the holders
of a  majority of  the  Fund's outstanding  voting  securities (which  for  this
purpose  and under the 1940 Act means the lesser of (i) 67% of the Fund's shares
present at a meeting  at which more  than 50% of the  outstanding shares of  the
Fund  are represented or (ii)  more than 50% of  the Fund's outstanding shares).
The Fund may not (1) purchase  any securities other than securities referred  to
under  "Investment Objective  and Policies"  herein and  in the  Prospectus; (2)
invest more than 25% of its total assets  (taken at market value at the time  of
each investment) in securities of issuers in any particular industry (other than
U.S.  Government securities or Government agency securities, Municipal Bonds and
Non-Municipal Tax-Exempt  Securities); (3)  invest more  than 10%  of its  total
assets  (taken at  market value  at the time  of each  investment) in industrial
revenue bonds where the entity supplying  the revenues from which the issuer  is
to  be paid, and  the guarantor of the  obligation, including predecessors, each
has a record of less than three years of continuous business operation; (4) make
investments for the purpose  of exercising control  or management; (5)  purchase
securities  of other investment  companies, except in  connection with a merger,
consolidation, acquisition or reorganization, and provided further that the Fund
may purchase  securities  of  closed-end  investment  companies  if  immediately
thereafter  not more than (i)  3% of the total  outstanding voting stock of such
company is owned  by the  Fund, (ii)  5% of the  Fund's total  assets, taken  at
market  value, would be  invested in any one  such company, or  (iii) 10% of the
Fund's  total  assets,  taken  at  market  value,  would  be  invested  in  such
securities;  (6) purchase  or sell real  estate (provided  that such restriction
shall not apply  to securities secured  by real estate  or interests therein  or
issued  by  companies  which  invest  in  real  estate  or  interests  therein),
commodities or commodity contracts (except that  the Fund may purchase and  sell
financial futures contracts), interests in oil, gas or other mineral exploration
or  development programs; (7) purchase any  securities on margin, except for use
of short-term credit necessary for clearance of purchases and sales of portfolio
securities (the deposit or payment by the Fund of initial or variation margin in
connection with financial futures contracts is not considered the purchase of  a
security  on margin);  (8) make  short sales of  securities or  maintain a short
position or invest in  put, call, straddle or  spread options (this  restriction
does
    

                                       13
<PAGE>
not  apply to options on  financial futures contracts); (9)  make loans to other
persons, provided that the Fund may purchase a portion of an issue of tax-exempt
securities (the acquisition of a portion of an issue of tax-exempt securities or
bonds, debentures or other debt securities which are not publicly distributed is
considered to be the making of a  loan under the 1940 Act) and provided  further
that  investments in repurchase agreements and purchase and sale contracts shall
not be deemed to be the making of  a loan; (10) borrow amounts in excess of  20%
of  its total assets, taken at market value (including the amount borrowed), and
then only  from banks  as a  temporary measure  for extraordinary  or  emergency
purposes  [Usually only "leveraged" investment companies may borrow in excess of
5% of their assets;  however, the Fund  will not borrow  to increase income  but
only  to  meet  redemption  requests  which  might  otherwise  require  untimely
disposition of portfolio securities. The Fund will not purchase securities while
borrowings are outstanding.  Interest paid  on such borrowings  will reduce  net
income];  (11)  mortgage,  pledge,  hypothecate or  in  any  manner  transfer as
security for indebtedness any securities owned or held by the Fund except as may
be necessary in  connection with borrowings  mentioned in (10)  above, and  then
such  mortgaging,  pledging or  hypothecating may  not exceed  10% of  its total
assets, taken at market value, or except as may be necessary in connection  with
transactions  in financial  futures contracts;  (12) invest  in securities which
cannot be readily resold because of  legal or contractual restrictions or  which
are  not  readily  marketable,  including  individually  negotiated  loans  that
constitute illiquid investments and illiquid lease obligations, or in repurchase
agreements or purchase and sale contracts maturing in more than seven days,  if,
regarding  all such securities, more than 15% of its net assets (taken at market
value), would be invested in such securities; and (13) 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 (12) above or insofar as
the Fund may  be deemed  an underwriter  under the  Securities Act  of 1933,  as
amended, in selling portfolio securities.

    In  addition,  to  comply  with tax  requirements  for  qualifications  as a
"regulated investment  company", the  Fund's investments  will be  limited in  a
manner  such that, at the close of each quarter of each fiscal year, (a) no more
than 25% of the Fund's total assets  are invested in the securities of a  single
issuer,  and (b) with regard to at least 50% of the Fund's total assets, no more
than 5% of its total assets are  invested in the securities of a single  issuer.
[For  purposes of  this restriction,  the Fund will  regard each  state and each
political  subdivision,  agency  or  instrumentality  of  such  state  and  each
multi-state  agency of which  such state is  a member and  each public authority
which issues securities  on behalf  of a private  entity as  a separate  issuer,
except  that if  the security  is backed only  by the  assets and  revenues of a
non-governmental entity then the entity with the ultimate responsibility for the
payment of interest  and principal may  be regarded as  the sole issuer.]  These
tax-related  limitations may  be changed  by the  Trustees of  the Trust  to the
extent necessary to comply with changes to the Federal tax requirements.

   
    PROPOSED UNIFORM  INVESTMENT RESTRICTIONS.  As discussed  in the  Prospectus
under  "Investment Objective and Policies -- Investment Restrictions", the Board
of Trustees 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
Fund Asset Management, L.P. (the "Investment Adviser") or its affiliate, Merrill
Lynch Asset Management, L.P. ("MLAM"). The investment objective and policies  of
the  Fund  will  be  unaffected  by  the  adoption  of  the  proposed investment
restrictions.
    

                                       14
<PAGE>
   
    Shareholders of the Funds 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. 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).
    

   
       2. Make investments for the purpose of exercising control or management.
    

   
       3. Purchase or sell real estate, except that, to the extent permitted  by
          applicable  law,  the  Fund  may  invest  in  securities  directly  or
    indirectly secured  by  real  estate  or  interests  therein  or  issued  by
    companies which invest in real estate or interests therein.
    

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

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

   
       6. Borrow money,  except that  (i) the  Fund may  borrow from  banks  (as
          defined in the 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.
    

   
       7. Underwrite securities  of other  issuers except  insofar as  the  Fund
          technically  may be deemed an underwriter  under the Securities Act of
    1933, as amended (the "Securities Act") in selling portfolio securities.
    

   
       8. Purchase or sell  commodities or contracts  on commodities, except  to
          the  extent that the Fund may do  so in accordance with applicable law
    and the Fund's Prospectus and  Statement of Additional Information, as  they
    may  be amended from  time to time,  and without registering  as a commodity
    pool operator under the Commodity Exchange Act.
    

   
    Under the  proposed non-fundamental  investment restrictions,  the Fund  may
not:
    

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

                                       15
<PAGE>
   
       b. Make short sales of securities or maintain a short position, except to
          the extent permitted by  applicable law. The  Fund currently does  not
    intend to engage in short sales, except short sales "against the box".
    

   
       c. Invest  in securities which cannot be  readily resold because of legal
          or contractual  restrictions or  which cannot  otherwise be  marketed,
    redeemed  or  put  to  the issuer  or  a  third  party, if  at  the  time of
    acquisition more than  15% of  its total assets  would be  invested in  such
    securities.  This  restriction shall  not apply  to securities  which mature
    within seven days or securities which the Board of Trustees of the Fund  has
    otherwise   determined   to   be   liquid   pursuant   to   applicable  law.
    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 that 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  that  Fund's total  assets  would  be  invested  in such
    securities. This restriction shall not apply to mortgage-backed  securities,
    asset-backed  securities  or obligations  issued or  guaranteed by  the U.S.
    Government, its agencies or instrumentalities.
    

   
       f. Purchase or retain the securities  of any issuer, if those  individual
          officers  and 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.
    

   
       i. Notwithstanding fundamental investment  restriction (6) above,  borrow
          amounts  in excess of 20%  of its total assets,  taken at market value
    (including the amount  borrowed), and then  only from banks  as a  temporary
    measure  for extraordinary or emergency purposes. In addition, the Fund will
    not purchase securities while borrowings are outstanding.
    

   
    Because of the  affiliation of  Merrill Lynch with  the Trust,  the Fund  is
prohibited  from engaging in certain transactions involving Merrill Lynch except
pursuant to a permissive order or otherwise in compliance with the provisions of
the 1940  Act and  the rules  and regulations  thereunder. Included  among  such
restricted  transactions  are  purchases  from  or  sales  to  Merrill  Lynch of
securities in transactions in which it
    

                                       16
<PAGE>
   
acts  as principal and  purchases of securities  from underwriting syndicates of
which Merrill  Lynch is  a member.  See "Portfolio  Transactions". An  exemptive
order has been obtained which permits the Trust to effect principal transactions
with Merrill Lynch in high quality, short-term, tax-exempt securities subject to
conditions set forth in such order.

- ---------
(1) Interested person, as defined in the 1940 Act, of the Trust.

(2) Such Trustee or officer is a director or officer of certain other investment
    companies for  which the  Manager  or MLAM  acts  as investment  adviser  or
    manager.

   
    At  August 31, 1994, the  Trustees and officers of the  Trust as a group (12
persons) owned an aggregate of less than 1/4 of 1% of the outstanding shares  of
Common Stock and owned an aggregate of less than 1% of the outstanding shares of
the Trust.
    

   
    The Trust pays each Trustee not affiliated with the Manager a fee of $10,000
per  year plus $1,000 per meeting  attended, together with such Trustee's actual
out-of-pocket expenses relating to attendance  at meetings. The Trust also  pays
members  of  its  Audit and  Nominating  Committee,  which consists  of  all the
non-affiliated Trustees,  a  fee  of  $2,000 per  year  plus  $500  per  meeting
attended.  Fees and expenses paid to the unaffiliated Trustees aggregated $2,511
for the year ended July 31, 1994.
    

MANAGEMENT AND ADVISORY ARRANGEMENTS

    Reference is made  to "Management of  the Trust --  Management and  Advisory
Arrangements"   in  the  Prospectus  for   certain  information  concerning  the
management and advisory arrangements of the Fund.

    Securities may be held  by, or be appropriate  investments for, the Fund  as
well  as  other funds  or  investment advisory  clients  of the  Manager  or its
affiliates. Because  of  different objectives  or  other factors,  a  particular
security  may be  bought for one  or more clients  when one or  more clients are
selling the same security. If purchases, or sales of securities for the Fund  or
other  funds for which they  act as manager or  for their advisory clients arise
for consideration at  or about the  same time, transactions  in such  securities
will be

                                       18
<PAGE>
made,  insofar as  feasible, for  the respective funds  and clients  in a manner
deemed equitable to all. To the extent that transactions on behalf of more  than
one  client of the Manager or its affiliates during the same period may increase
the demand for  securities being  purchased or  the supply  of securities  being
sold, there may be an adverse effect on price.

   
    Pursuant  to a management agreement between the  Trust on behalf of the Fund
and the  Manager (the  "Management  Agreement"), the  Manager receives  for  its
services  to  the Fund  monthly compensation  based upon  the average  daily net
assets of the Fund at the following annual rates: 0.55% of the average daily net
assets not  exceeding $500  million;  0.525% of  the  average daily  net  assets
exceeding  $500 million but not exceeding $1.0 billion; and 0.50% of the average
daily net assets  exceeding $1.0  billion. For the  fiscal year  ended July  31,
1994,  the total  advisory fee  payable by  the Fund  to the  Manager aggregated
$383,179, all of which was voluntarily waived.
    

   
    The  Management  Agreement  obligates  the  Manager  to  provide  investment
advisory  services and to pay  all compensation of and  furnish office space for
officers and  employees of  the  Trust connected  with investment  and  economic
research, trading and investment management of the Trust, as well as the fees of
all  Trustees of the Trust  who are affiliated persons of  the Manager or any of
its subsidiaries. The  Fund pays all  other expenses incurred  in its  operation
and,  if any other  series shall be  added ("Series"), a  portion of the Trust's
general administrative expenses allocated on the basis of the asset size of  the
respective  Series. Expenses that will be  borne directly by the Series include,
among other  things, redemption  expenses, expenses  of portfolio  transactions,
expenses  of registering  the shares  under Federal  and state  securities laws,
pricing costs (including the daily calculation of net asset value), expenses  of
printing   shareholder  reports,  prospectuses   and  statements  of  additional
information (except to the extent paid  by the Distributor as described  below),
fees  for legal and auditing services, Commission fees, interest, certain taxes,
and other expenses attributable to a  particular Series. Expenses which will  be
allocated  on the basis of asset size  of the respective Series include fees and
expenses of  unaffiliated Trustees,  state franchise  taxes, costs  of  printing
proxies  and other expenses related to  shareholder meetings, and other expenses
properly payable by  the Trust. The  organizational expenses of  the Trust  were
paid  by  the  Trust, and  as  additional Series  are  added to  the  Trust, the
organizational expenses are allocated among the Series (including the Fund) in a
manner deemed equitable by the Trustees. Depending upon the nature of a lawsuit,
litigation costs may  be assessed to  the specific Series  to which the  lawsuit
relates  or allocated on the  basis of the asset  size of the respective Series.
The Trustees have determined that this is an appropriate method of allocation of
expenses. Accounting services are  provided to the Fund  by the Manager and  the
Fund  reimburses the Manager for its costs in connection with such services. For
the year  ended  July 31,  1994  the Fund  reimbursed  the Manager  $45,746  for
accounting  services.  As required  by the  Fund's distribution  agreements, the
Distributor will pay the promotional expenses of the Fund incurred in connection
with the offering  of shares of  the Fund. Certain  expenses in connection  with
account  maintenance and the distribution of Class  B shares will be financed by
the Fund pursuant to the Distribution  Plan in compliance with Rule 12b-1  under
the 1940 Act. See "Purchase of Shares -- Distribution Plan".
    

   
    The  Manager is a limited  partnership, the partners of  which are ML & Co.,
Fund Asset Management, Inc. and Princeton Services, Inc.
    

   
    DURATION AND TERMINATION. Unless earlier terminated as described herein, the
Management Agreement  will  remain in  effect  from  year to  year  if  approved
annually  (a) by the Trustees  of the Trust or by  a majority of the outstanding
shares of the Fund and (b) by a majority of the Trustees who are not parties  to
such contract
    

                                       19
<PAGE>
or  interested persons  (as defined  in the  1940 Act)  of any  such party. Such
contracts are not assignable and may  be terminated without penalty on 60  days'
written  notice  at  the  option of  either  party  thereto or  by  vote  of the
shareholders of the Fund.

                               PURCHASE OF SHARES

    Reference is made  to "Purchase  of Shares"  in the  Prospectus for  certain
information as to the purchase of Fund shares.

   
    The  Fund  issues four  classes  of shares  under  the Merrill  Lynch Select
Pricing System: shares of Class A and Class D are sold to investors choosing the
initial sales charge alternatives, and shares of Class B and Class C are sold to
investors choosing the deferred sales  charge alternatives. Each Class A,  Class
B,  Class C and Class D share of  the Fund represents identical interests in the
investment portfolio of the Fund and has  the same rights, except that Class  B,
Class  C and Class D shares bear the expenses of the ongoing account maintenance
fees, and  Class  B  and  Class  C shares  bear  the  expenses  of  the  ongoing
distribution fees and the additional incremental transfer agency costs resulting
from the deferred sales charge arrangements. Class B, Class C and Class D shares
each  have exclusive voting  rights with respect to  the Rule 12b-1 distribution
plan adopted with respect  to such class pursuant  to which account  maintenance
and/or distribution fees are paid. Each class has different exchange privileges.
See "Shareholder Services -- Exchange Privilege".
    

   
    The Merrill Lynch Select Pricing System is used by more than 50 mutual funds
advised  by MLAM  or its affiliate,  the Manager.  Funds advised by  MLAM or the
Manager are referred to herein as "MLAM-advised mutual funds".
    

   
    The Fund has  entered into  four separate distribution  agreements with  the
Distributor  in connection with the continuous  offering of each class of shares
of  the  Fund  (the  "Distribution  Agreements").  The  Distribution  Agreements
obligate the Distributor to pay certain expenses in connection with the offering
of  each class  of shares  of the  Fund. After  the prospectuses,  statements of
additional information and periodic reports have been prepared, set in type  and
mailed  to shareholders, the Distributor pays  for the printing and distribution
of  copies  thereof  used  in  connection  with  the  offering  to  dealers  and
prospective  investors. The Distributor also  pays for other supplementary sales
literature and advertising costs. The Distribution Agreements are subject to the
same renewal requirements and termination provisions as the Management Agreement
described above.
    

   
INITIAL SALES CHARGE ALTERNATIVES--CLASS A AND CLASS D SHARES
    
   
    The Fund commenced the public offering of its Class A shares on January  29,
1993.  The gross sales charges for the sale of Class A shares for the year ended
July 31,  1994, were  $57,585,  of which  the  Distributor received  $7,508  and
Merrill Lynch received $50,077.
    

   
    The  term  "purchase",  as used  in  the  Prospectus and  this  Statement of
Additional Information in connection with an  investment in Class A and Class  D
shares  of  the  Fund, refers  to  a single  purchase  by an  individual,  or to
concurrent purchases,  which  in  the  aggregate  are  at  least  equal  to  the
prescribed  amounts, by an  individual, his spouse and  their children under the
age of 21 years  purchasing shares for  his or their own  account and to  single
purchases  by a trustee or other fiduciary  purchasing shares for a single trust
estate or  single  fiduciary  account  although more  than  one  beneficiary  is
involved.  The term "purchase" also includes purchases by any "company", as that
term  is   defined  in   the  1940   Act,  but   does  not   include   purchases
    

                                       20
<PAGE>
by  any such company which has not been  in existence for at least six months or
which has no purpose other than the purchase of shares of the Fund or shares  of
other  registered investment companies at a discount; provided, however, that it
shall  not  include   purchases  by   any  group  of   individuals  whose   sole
organizational  nexus is that the participants therein are credit cardholders of
a company, policyholders of an insurance company, customers of either a bank  or
broker-dealer or clients of an investment adviser.

   
    CLOSED-END  INVESTMENT  OPTION.  Class  A  shares  of  the  Fund  and  other
MLAM-advised mutual funds ("Eligible Class A  shares") are offered at net  asset
value to shareholders of certain closed-end funds advised by the Manager or MLAM
who  purchased such closed-end fund shares prior to October 21, 1994 and wish to
reinvest the net proceeds of a sale of their closed-end fund shares in  Eligible
Class  A shares, if the conditions set forth below are satisfied. Alternatively,
closed-end fund shareholders who purchased such  shares on or after October  21,
1994  and wish to reinvest the net proceeds from a sale of their closed-end fund
shares are offered Class A shares (if eligible to buy Class A shares) or Class D
shares of  the Fund  and  other MLAM-advised  mutual  funds ("Eligible  Class  D
Shares"),  if the  following conditions are  met. First, the  sale of closed-end
fund shares must be made through  Merrill Lynch, and the net proceeds  therefrom
must  be immediately reinvested in  Eligible Class A or  Class D shares. Second,
the closed-end fund shares must either have been acquired in the initial  public
offering  or  be  shares  representing dividends  from  shares  of  common stock
acquired in such  offering. Third,  the closed-end  fund shares  must have  been
continuously  maintained in  a Merrill  Lunch 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.
    

   
REDUCED INITIAL SALES CHARGES
    
   
    RIGHT  OF ACCUMULATION. Reduced sales charges are applicable through a right
of accumulation under which eligible investors are permitted to purchase Class A
shares of the  Fund subject to  an initial  sales charge at  the offering  price
applicable  to the  total of (a)  the public  offering price of  the shares then
being purchased plus (b) an amount equal to the then current net asset value  or
cost,  whichever is higher, of the  purchaser's combined holdings of all classes
of shares of the Fund and of  any other MLAM-advised mutual funds. For any  such
right  of accumulation to be made available, the Distributor must be provided at
the time of  purchase, by the  purchaser or the  purchaser's securities  dealer,
with  sufficient information to permit confirmation of qualification. Acceptance
of the purchase order is subject to such confirmation. The right of accumulation
may be amended or terminated at any time.  Shares held in the name of a  nominee
or  custodian under pension, profit-sharing or  other employee benefit plans may
not be combined with other shares to qualify for the right of accumulation.
    

                                       21
<PAGE>
   
    LETTER OF  INTENTION.  Reduced sales  charges  are applicable  to  purchases
aggregating  $25,000 or more of the Class A or Class D shares of the Fund or any
other MLAM-advised mutual funds made within a 13 month period starting with  the
first  purchase pursuant to  a Letter of  Intention in the  form provided in the
Prospectus. The  Letter  of  Intention  is available  only  to  investors  whose
accounts are maintained at the Fund's transfer agent. The Letter of Intention is
not  available to employee  benefit plans for which  Merrill Lynch provides plan
participant, record-keeping services. The Letter  of Intention is not a  binding
obligation  to purchase any  amount of Class  A or Class  D shares; however, its
execution will  result in  the purchaser  paying  a lower  sales charge  at  the
appropriate  quantity purchase level. A purchase not originally made pursuant to
a Letter of  Intention may be  included under a  subsequent Letter of  Intention
executed  within 90  days of  such purchase  if the  Distributor is  informed in
writing of this intent within such 90-day period. The value of Class A and Class
D shares of the Fund and of  other MLAM-advised mutual funds presently held,  at
cost  or maximum offering price (whichever is  higher), on the date of the first
purchase under the Letter of Intention, may  be included as a credit toward  the
completion of such Letter, but the reduced sales charge applicable to the amount
covered  by such  Letter will  be applied  only to  new purchases.  If the total
amount of shares does  not equal the  amount stated in  the Letter of  Intention
(minimum of $25,000), the investor will be notified and must pay, within 20 days
of the expiration of such Letter, the difference between the sales charge on the
Class  A or Class  D shares purchased at  the reduced rate  and the sales charge
applicable to the shares actually purchased through the Letter. Class A or Class
D shares equal to at least five percent  of the intended amount will be held  in
escrow during the 13 month period (while remaining registered in the name of the
purchaser)  for this purpose.  The first purchase under  the Letter of Intention
must be at least five percent of the dollar amount of such Letter. If a purchase
during the term of such Letter, would otherwise be subject to a further  reduced
sales  charge  based  on the  right  right  accumulation the  purchaser  will be
entitled on  that purchase  and  subsequent purchases  to that  further  reduced
percentage sales charge, but there will be no retroactive reduction of the sales
charges  on any previous purchase. The value of any shares redeemed or otherwise
disposed of by the purchaser prior to termination or completion of the Letter of
Intention will be deducted from the  total purchases made under such Letter.  An
exchange  from a  MLAM-advised money  market fund into  the Fund  that creates a
sales charge will count toward completing a new or existing Letter of  Intention
from the Fund.
    

   
    TMA-SM- MANAGED TRUSTS. Class A shares are offered to TMA-SM- Managed Trusts
to  which Merrill Lynch Trust Company provides discretionary trustee services at
net asset value.
    

   
    PURCHASE PRIVILEGE OF CERTAIN PERSONS. Trustees of the Trust and members  of
the  Boards of other MLAM-advised  investment companies, directors and employees
of ML & Co. and its subsidiaries 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 or  purchase or an 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 must  had maintained in  the interim  in cash or  a money  market
fund.

    Class  D shares  of the Fund  are also  offered at net  asset value, without
sales charge, to  an investor  who has a  business relationship  with a  Merrill
Lynch  financial consultant and who has invested in a mutual fund sponsored by a
non-Merrill Lynch  company for  which Merrill  Lynch has  served as  a  selected
dealer  and where Merrill  Lynch has either  received or given  notice that such
arrangement will  be  terminated ("notice"),  if  the following  conditions  are
satisfied:  First, the investor  must purchase Class  D shares of  the Fund with
proceeds from a redemption of shares of such other mutual fund and such fund was
subject to a sales charge either at the time of purchase or an 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 a
sales charge, to  an investor  who has a  business relationship  with a  Merrill
Lynch  financial consultant  and who  has invested  in a  mutual fund  for which
Merrill Lynch has not  served as a selected  dealer if the following  conditions
are  satisfied:  First, the  investor  must advise  Merrill  Lynch that  it will
purchase Class D shares of  the Fund with proceeds  from the redemption of  such
shares  of other mutual funds  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.
    

   
    ACQUISITION  OF CERTAIN INVESTMENT  COMPANIES. The public  offering price of
Class D shares  may be  reduced to  the net  asset value  per Class  D share  in
connection with the acquisition of the assets of or merger or consolidation with
a  personal holding company or a public or private investment company. The value
of the assets or company acquired in  a tax-free transaction may be adjusted  in
appropriate  cases to reduce possible adverse tax consequences to the Fund which
might result from an  acquisition of assets  having net unrealized  appreciation
which  is disproportionately higher at the time of acquisition than the realized
or unrealized  appreciation of  the Fund.  The issuance  of Class  D shares  for
consideration other than cash is limited to bona fide reorganizations, statutory
mergers  or  other  acquisitions  of portfolio  securities  which  (i)  meet the
investment objectives and policies of the Fund; (ii) are acquired for investment
and not for  resale (subject to  the understanding that  the disposition of  the
Fund's  portfolio securities shall at all  times remain within its control); and
(iii) are liquid securities, the value of which is readily ascertainable,  which
are  not restricted as to transfer either  by law or liquidity of market (except
that the  Fund may  acquire  through such  transactions restricted  or  illiquid
securities  to the  extent the  Fund does  not exceed  the applicable  limits on
acquistion  of  such  securities  set  forth  under  "Investment  Objective  and
Policies" herein).
    

   
    Reductions  in or exemptions from the imposition  of a sales load are due to
the nature of the investors and/or the reduced sales efforts that will be needed
in obtaining such investments.
    

   
DISTRIBUTION PLANS
    
   
    Reference is  made to  "Purchase of  Shares --  Distribution Plans"  in  the
Prospectus  for certain  information with  respect to  the separate distribution
plans for Class B, Class C and Class  D shares pursuant to Rule 12b-1 under  the
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.
    

   
    Payments  of  the  account  maintenance fees  and/or  distribution  fees are
subject to the provisions of Rule 12b-1 under the 1940 Act. Among other  things,
each  Distribution  Plan provides  that the  Distributor  shall provide  and the
Trustees shall  review quarterly  reports  of the  disbursement of  the  account
maintenance   and/or  distribution  fees  paid  to  the  Distributor.  In  their
consideration of each Distribution Plan, the Trustees
    

                                       23
<PAGE>
   
must consider all factors  they deem relevant, including  information as to  the
benefits  of  the  Distribution  Plan  to the  Fund  and  its  related  class of
shareholders. Each  Distribution Plan  further  provides that,  so long  as  the
Distribution  Plan remains in  effect, the selection  and nomination of Trustees
who are not "interested persons" of the  Trust, as defined in the 1940 Act  (the
"Independent Trustees"), shall be committed to the discretion of the Independent
Trustees  then in office. In approving each Distribution Plan in accordance with
Rule  12b-1,  the  Independent  Trustees  concluded  that  there  is  reasonable
likelihood  that each  Distribution Plan will  benefit the Fund  and its related
class of shareholders.  Each Distribution Plan  can be terminated  at any  time,
without penalty, by the vote of a majority of the Independent Trustees or by the
vote  of the holders  of a majority  of the outstanding  related class of voting
securities of  the Fund.  A  Distribution Plan  cannot  be amended  to  increase
materially  the  amount to  be spent  by the  Fund without  the approval  of the
related class of shareholders,  and all material amendments  are required to  be
approved  by  the vote  of  Trustees, including  a  majority of  the Independent
Trustees who have no direct or indirect financial interest in such  Distribution
Plan,  cast in person at  a meeting called for  that purpose. Rule 12b-1 further
requires that the Trust preserve copies of each Distribution Plan and any report
made pursuant to such plan for a period of not less than six years from the date
of such Distribution  Plan or  such report,  the first  two years  in an  easily
accessible place.
    

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

    The  following table sets forth comparative information as of July 31, 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 year ended July 31, 1994. Since Class  C
shares  of the  Fund had  not been  publicly issued  prior to  the date  of this
Statement of Additional  Information, information concerning  Class C shares  is
not yet provided below.

                              REDEMPTION OF SHARES

    Reference is made to  "Redemption of Shares" in  the Prospectus for  certain
information as to the redemption and repurchase of Fund shares.

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

   
DEFERRED SALES CHARGES--CLASS B SHARES
    
   
    As discussed in the Prospectus under  "Purchase of Shares -- Deferred  Sales
Charge  Alternatives  -- Class  B  and Class  C  Shares", while  Class  B shares
redeemed within  four  years  of purchase  are  subject  to a  CDSC  under  most
circumstances,  the charge is waived on  redemptions of Class B shares following
the death or  disability of  a Class B  shareholder. Redemptions  for which  the
waiver  applies are  any partial or  complete redemption following  the death or
disability (as  defined in  the Code  of a  Class B  shareholder (including  one
    

                                       25
<PAGE>
   
who  owns the Class B  shares as joint tenant with  his or her spouse), provided
the  redemption  is  requested  within  one   year  of  the  death  or   initial
determination  of disability. For the year  ended July 31, 1994, the Distributor
received CDSCs of $100,415, all of which was paid to Merrill Lynch.
    

                             PORTFOLIO TRANSACTIONS

    Reference is  made to  "Investment Objective  and Policies"  and  "Portfolio
Transactions" in the Prospectus.

   
    Under  the 1940 Act,  persons affiliated with the  Trust are prohibited from
dealing with the  Fund as a  principal in  the purchase and  sale of  securities
unless such trading is permitted by an exemptive order issued by the Commission.
Since   over-the-counter  transactions   are  usually   principal  transactions,
affiliated persons  of the  Trust, including  Merrill Lynch,  may not  serve  as
dealer  in connection with transactions with the Fund. The Trust has obtained an
exemptive order permitting it to  engage in certain principal transactions  with
Merrill  Lynch  involving high  quality  short-term municipal  bonds  subject to
certain conditions. For the  year ended July  31, 1994, the  Fund engaged in  no
transactions  pursuant to such order. Affiliated  persons of the Trust may serve
as broker for the Fund in  over-the-counter transactions conducted on an  agency
basis.  Certain court decisions have raised questions  as to the extent to which
investment companies should seek exemptions under the 1940 Act in order to  seek
to  recapture  underwriting and  dealer  spreads from  affiliated  entities. The
Trustees  have  considered  all  factors  deemed  relevant,  and  have  made   a
determination  not  to  seek  such  recapture at  this  time.  The  Trustee will
reconsider this matter from time to time.
    

    Under the  1940  Act,  the  Fund may  not  purchase  securities  during  the
existence  of  any underwriting  syndicate of  which Merrill  Lynch is  a member
except pursuant to an exemptive order  or rules adopted by the Commission.  Rule
10f-3 under the 1940 Act sets forth conditions under which the Fund may purchase
municipal  bonds in such transactions. The rule sets forth requirements relating
to, among other things, the  terms of an issue  of municipal bonds purchased  by
the  Fund, the amount of municipal bonds which may be purchased in any one issue
and the assets of the Fund which may be invested in a particular issue.

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

    The  Trust has  no obligation to  deal with  any broker in  the execution of
transactions for the Fund's portfolio  securities. In addition, consistent  with
the  Rules of Fair  Practice of the National  Association of Securities Dealers,
Inc. and policies  established by  the Trustees of  the Trust,  the Manager  may
consider  sales of shares of the Fund as a factor in the selection of brokers or
dealers to execute portfolio transactions for the Fund.

    Generally, the  Fund does  not purchase  securities for  short-term  trading
profits.  However, the Fund may dispose of securities without regard to the time
they have been held  when such action, for  defensive or other reasons,  appears
advisable  to its Manager.  While it is  not possible to  predict turnover rates
with any  certainty,  at  present  it is  anticipated  that  the  Fund's  annual
portfolio  turnover rate, under normal  circumstances after the Fund's portfolio
is invested  in accordance  with its  investment objective,  will be  less  than

                                       26
<PAGE>
   
100%.  (The  portfolio turnover  rate is  calculated by  dividing the  lesser of
purchases or sales of portfolio securities for the particular fiscal year by the
monthly average  of the  value of  the portfolio  securities owned  by the  Fund
during  the particular fiscal  year. For purposes of  determining this rate, all
securities whose maturities at the time of acquisition are one year or less  are
excluded.) The portfolio turnover for the year ended July 31, 1994, was 71.70%.
    

                        DETERMINATION OF NET ASSET VALUE

   
    The  net asset value  of the Fund  is determined by  the Manager once daily,
Monday through Friday, as of 4:15 P.M.,  New York City time, on each day  during
which  the  New York  Stock Exchange  is open  for trading.  The New  York Stock
Exchange is not open on New  Year's Day, Good Friday, Presidents' Day,  Memorial
Day,  Independence Day, Labor Day, Thanksgiving Day and Christmas Day. Net asset
value per share is computed by dividing  the sum of the value of the  securities
held  by the  Fund plus any  cash or other  assets minus all  liabilities by the
total number of shares  outstanding at such time,  rounded to the nearest  cent.
Expenses, including the fees payable to the Manager and Distributor, are accrued
daily.  The per share net asset value of Class B, Class C and Class D shares may
be lower than the  per share net  asset value of Class  A shares reflecting  the
higher  daily  expense accruals  of  the account  maintenance,  distribution and
transfer agency fees applicable with respect to  Class B and Class C shares  and
the  daily  expense accruals  of the  account  maintenance fees  applicable with
respect to 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 of the Fund. Even under those circumstances, the per
share net asset  value of  the four classes  will tend  to converge  immediately
after the payment of dividends, which will differ by approximately the amount of
the expense accrual differential between the classes.
    

    The Municipal Bonds and other portfolio securities in which the Fund invests
are  traded primarily in  over-the-counter municipal bond  and money markets and
are valued at the last available bid price in the over-the-counter market or  on
the  basis of yield equivalents  as obtained from one  or more dealers that make
markets in the securities.  One bond is the  "yield equivalent" of another  bond
when, taking into account market price, maturity, coupon rate, credit rating and
ultimate   return  of  principal,  both  bonds  will  theoretically  produce  an
equivalent return to  the bondholder.  Financial futures  contracts and  options
thereon, which are traded on exchanges, are valued at their settlement prices as
of the close of such exchanges. Short-term investments with a remaining maturity
of 60 days or less are valued on an amortized cost basis, which approximates the
market.  Securities  and  assets for  which  market quotations  are  not readily
available are valued at fair value as  determined in good faith by or under  the
direction  of the  Trustees of  the Trust,  including valuations  furnished by a
pricing service retained  by the Trust,  which may utilize  a matrix system  for
valuations.  The  procedures  of  the pricing  service  and  its  valuations are
reviewed by  the officers  of the  Trust under  the general  supervision of  the
Trustees.

                              SHAREHOLDER SERVICES

   
    The  Trust offers a number of shareholder services described below which are
designed to facilitate investment in shares of the Fund. Full details as to each
of such services and copies of the various plans described below can be obtained
from the Trust, the Distributor or Merrill Lynch.
    

                                       27
<PAGE>
INVESTMENT ACCOUNT
   
    Each shareholder whose account  is maintained at the  Transfer Agent has  an
Investment  Account and  will receive  statements; at  least quarterly  from the
Transfer  Agent  showing  any  reinvestment  of  dividends  and  capital   gains
distributions activity in the account since the previous statement. Shareholders
also  will receive separate confirmations for  each purchase or sale transaction
other  than  reinvestment   of  dividends  and   capital  gains   distributions.
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 so that the  cash proceeds can be transferred  to
the  account at the  new firm or  such shareholder must  continue to maintain an
Investment Account at the Transfer  Agent for those Class  A or Class D  shares.
Shareholders  interested in  transferring their Class  B or Class  C shares from
Merrill Lynch and who do not wish  to have an Investment Account maintained  for
such  shares  at the  Transfer Agent  may  request their  new brokerage  firm to
maintain such shares in an account registered in the name of the brokerage  firm
for  the benefit  of the shareholder.  If the  new brokerage firm  is willing to
accommodate the shareholder in this manner, the shareholder must request that he
be issued certificates for his shares, and then must turn the certificates  over
to  the new firm for  re-registration as described in  the preceding sentence. A
shareholder may make additions to his Investment Account at any time by  mailing
a check directly to the Transfer Agent.
    

    Share  certificates  are  issued only  for  full  shares and  only  upon the
specific request of the shareholder who  has an Investment Account. Issuance  of
certificates  representing all or only part of  the full shares in an Investment
Account may be requested by a shareholder directly from the Transfer Agent.

   
AUTOMATIC INVESTMENT PLANS
    
   
    A shareholder may  make additions to  an Investment Account  at any time  by
purchasing  Class A  shares (if  he or she  is an  eligible Class  A investor as
described in  the Prospectus)  or Class  B, Class  C or  Class D  shares at  the
applicable  public offering  price either  through the  shareholder's securities
dealer, or by  mail directly to  the Transfer  Agent, acting as  agent for  such
securities  dealers. Voluntary accumulation  also can be  made through a service
known as the Automatic  Investment Plan whereby the  Fund is authorized  through
pre-authorized  checks  or automated  clearing house  debits of  $50 or  more to
charge the regular bank account of the shareholder on a regular basis to provide
systematic  additions   to  the   Investment   Account  of   such   shareholder.
Alternatively,  investors  who  maintain  CMA-R- accounts  may  arrange  to have
periodic investments made  in the Fund  in their CMA-R-  accounts or in  certain
related  accounts  in  amounts of  $100  or  more through  the  CMA-R- Automated
Investment Program.
    

AUTOMATIC REINVESTMENT OF DIVIDENDS AND CAPITAL GAINS DISTRIBUTIONS
   
    Unless specific  instructions are  given  as to  the  method of  payment  of
dividends  and capital gains distributions,  dividends and distributions will be
reinvested automatically in  additional shares  of the  Fund. Such  reinvestment
will be at the net asset value of shares of the Fund as of the close of business
on  the monthly payment date for  such dividends and distributions. Shareholders
may elect in writing to receive  either their income dividends or capital  gains
distributions, or both, in cash, in which event payment will be mailed or direct
deposited on or about the payment date.
    

                                       28
<PAGE>
    Shareholders  may, at any time,  notify the Transfer Agent  in writing or by
telephone (1-800-MER-FUND)  that they  no longer  wish to  have their  dividends
and/or  capital gains  distributions reinvested  in shares  of the  Fund or vice
versa and, commencing ten days after the  receipt by the Transfer Agent of  such
notice, such instructions will be effected.

   
SYSTEMATIC WITHDRAWAL PLANS--CLASS A AND CLASS D SHARES
    
   
    A  Class A or Class  D shareholder may elect  to make systematic withdrawals
from an Investment Account  on either a monthly  or quarterly basis as  provided
below.  Quarterly withdrawals are  available for shareholders  who have acquired
Class A or  Class D shares  of the  Fund having a  value, based on  cost or  the
current offering price, of $5,000 or more, and monthly withdrawals are available
for  shareholders with Class A or Class D shares with such a value of $10,000 or
more.
    

   
    At the time of each withdrawal payment, sufficient Class A or Class D shares
are redeemed from those on deposit  in the shareholder's account to provide  the
withdrawal  payment specified  by the  shareholder. The  shareholder may specify
either a dollar amount or a  percentage of the value of  his Class A or Class  D
shares.  Redemptions will be made at net asset value as determined at the normal
close of business on the New York Stock Exchange (currently 4:00 P.M., New  York
City  time) on the 24th day  of each month or the 24th  day of the last month of
each quarter, whichever is applicable. If the Exchange is not open for  business
on  such date, the Class  A or Class D  shares will be redeemed  at the close of
business on the  following business day.  The check for  the withdrawal  payment
will  be mailed, or the direct deposit  for the withdrawal payment will be made,
on the next  business day  following redemption.  When a  shareholder is  making
systematic  withdrawals, dividends and  distributions on all Class  A or Class D
shares in  the Investment  Account are  reinvested automatically  in the  Fund's
Class  A or Class  D shares respectively.  A shareholder's Systematic Withdrawal
Plan may  be  terminated  at  any  time,  without  charge  or  penalty,  by  the
shareholder,  the  Trust,  the  Transfer Agent  or  the  Distributor. Withdrawal
payments should not be considered as dividends, yield or income. Each withdrawal
is a  taxable  event. If  periodic  withdrawals continuously  exceed  reinvested
dividends, the shareholder's original investment may be reduced correspondingly.
Purchases  of additional Class  A or Class D  shares concurrent with withdrawals
are ordinarily disadvantageous to the  shareholder because of sales charges  and
tax liabilities. The Trust will not knowingly accept purchase orders for Class A
or  Class  D  shares  of  the Fund  from  investors  who  maintain  a Systematic
Withdrawal Plan unless such purchase is  equal to at least one year's  scheduled
withdrawals  or $1,200,  whichever is greater.  Periodic investments  may not be
made into an  Investment Account in  which the shareholder  has elected to  make
systematic withdrawals.
    

   
    A  Class A or Class  D shareholder whose shares are  held within a CMA-R- or
CBA-R- account  may elect  to  have shares  redeemed  on a  monthly,  bimonthly,
quarterly, semiannual or annual basis through the 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
redemption  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  Company 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 each of  the Fund have an  exchange
privilege  with certain other MLAM-advised mutual  funds listed below. Under the
Merrill Lynch Select Pricing System, Class  A shareholders may exchange Class  A
shares  of a Fund for Class A shares of a second MLAM-advised mutual fund if the
shareholder holds any Class A shares of the second fund in his account in  which
the  exchange is made  at the time of  the exchange or  is otherwise eligible to
purchase Class A shares of the second fund. If the Class A shareholder wants  to
exchange Class A shares for shares of a second MLAM-advised mutual fund, and the
shareholder  does not hold Class  A shares of the second  fund in his account at
the time of the exchange and is not otherwise eligible to acquire Class A shares
of the second fund, the  shareholder will receive Class  D shares of the  second
fund as a result of the exchange. Class D shares also may be exchanged for Class
A  shares of a  second MLAM-advised mutual fund  at any time as  long as, at the
time of the exchange, the shareholder holds Class A shares of the second fund in
the account in which the exchange is  made or is otherwise eligible to  purchase
Class  A shares of the second fund. Class B,  Class C and Class D shares will be
exchangeable with shares of the same  class of other MLAM-advised mutual  funds.
For purposes of computing the CDSC that may be payable upon a disposition of the
shares  acquired in  the exchange, the  holding period for  the previously owned
shares of a Fund is "tacked" to the holding period of the newly acquired  shares
of  the other Fund as more fully described  below. Class A, Class B, Class C and
Class D shares  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, and
any shares utilized in an exchange must have been held by the shareholder for 15
days. It is contemplated that the exchange privilege may be applicable to  other
new mutual funds whose shares may be distributed by the Distributor.
    

   
    Exchanges  of Class A or Class D shares outstanding ("outstanding Class A or
Class D shares")  for Class A  or Class  D shares of  other MLAM-advised  mutual
funds  ("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 shares. With respect to outstanding Class  A
shares  as  to which  previous  exchanges have  taken  place, the  "sales charge
previously paid" shall  include the  aggregate of  the sales  charges paid  with
respect  to such  Class A  or Class  D shares  in the  initial purchase  and any
subsequent exchange.  Class A  or Class  D shares  issued pursuant  to  dividend
reinvestment  are sold on a no-load basis in  each of the funds offering Class A
or Class D shares. For purposes of  the exchange privilege, Class A and Class  D
shares  acquired through dividend reinvestment shall be deemed to have been sold
with a sales charge equal to the sales charge previously paid on the Class A  or
Class  D shares on which  the dividend was paid. Based  on this formula, Class A
and Class D shares of  the Fund generally may be  exchanged into the Class A  or
Class  D shares of  the other funds  or into shares  of the Class  A and Class D
money market funds without a sales charge.
    

   
    In addition, each of the funds with  Class B and Class C shares  outstanding
offers  to exchange its Class B or Class C  shares for Class B or Class C shares
respectively of another MLAM-advised mutual fund ("new
    

                                       30
<PAGE>
   
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 CSDC that might otherwise be due on
redemption  of  the  outstanding  shares.  Class  B  shareholders  of  the  Fund
exercising the exchange privilege will continue to be subject to the Fund's CSDC
schedule  if such schedule is higher than  the CDSC schedule relating to the new
Class B shares  acquired through  use of  the exchange  privilege. In  addition,
Class  B shares of the Fund acquired  through use of the exchange privilege will
be subject  to the  Fund's contingent  deferred sales  charge schedule  if  such
schedule  is higher than the CDSC schedule relating to the Class B shares of the
fund from which the exchange has been made. For purposes of computing the  sales
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 or Class  C shares  is
"tacked"  to  the holding  period of  the new  Class  B or  Class C  shares. For
example, an  investor may  exchange Class  B shares  of the  Fund for  those  of
Merrill  Lynch Special Value  Fund ("Special Value Fund")  after having held the
Fund's Class  B shares  for two  and  a half  years. The  2% sales  charge  that
generally  would apply to  a redemption would  not apply to  the exchange. Three
years later the investor may decide to redeem the Class B shares of the  Special
Value Fund and receive cash. There will be no CDSC due on this redemption, since
by "tacking" the two and a half year holding period of the Fund's Class B shares
to  the three year holding period for the Special Value Fund Class B shares, the
investor will be deemed to have held the  new Class B shares for more than  five
years.
    

   
    Shareholders  also may exchange  shares of the  Fund into shares  of a money
market fund advised by  the Manager of  its affiliates, but  the period of  time
that  Class B or Class C shares are held in a Class B money market fund will not
count towards satisfaction  of the  holding period requirement  for purposes  of
reducing  the CDSC or, with  respect to Class B  shares, towards satisfaction of
the conversion  period.  However, shares  of  a  money market  fund  which  were
acquired as a result of an exchange for Class B or Class C shares of a Fund may,
in  turn, be exchanged back into Class B or Class C shares, respectively, of any
fund offering such  shares, in which  event the  holding period for  Class B  or
Class  C shares of the 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   a  Fund  for   shares  of  Merrill   Lynch  Institutional   Fund
("Institutional Fund") after having held the Fund's Class B shares for two and a
half  years and three years  later decide to redeem  the shares of Merrill Lynch
Institutional Fund for cash. At  the time of this  redemption, the 2% CDSC  that
would  have been due had the  Class B shares of the  Fund been redeemed for cash
rather than exchanged  for sales  of Merrill  Lynch 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 continues to  hold for  an
additional  two and  a half  years, any subsequent  redemption will  not incur a
CDSC.
    

   
    Set forth below is a description  of the investment objectives of the  other
funds into which exchanges can be made:

                            DISTRIBUTIONS AND TAXES

   
    The  Trust  intends to  continue to  qualify  the Fund  for the  special tax
treatment afforded regulated  investment companies ("RICs")  under the  Internal
Revenue  Code of 1986, as amended. If the Fund so qualifies, in any taxable year
in which it distributes at  least 90% of its taxable  net income and 90% of  its
tax-exempt  net income (see below), the Fund (but not its shareholders) will not
be subject to  Federal income  tax to  the extent  that it  distributes its  net
investment income and net realized capital gains. The Trust intends to cause the
Fund to distribute substantially all of such income.
    

   
    As  discussed  in the  Fund's Prospectus,  the  Trust has  established other
series in addition  to the  Fund (together with  the Fund,  the "Series").  Each
Series  of the Trust is treated as a separate corporation for Federal income tax
purposes. Each  Series, therefore,  is considered  to be  a separate  entity  in
determining  its treatment under the rules for RICs described in the Prospectus.
Losses in one Series do not offset gains in another Series, and the requirements
(other than certain organizational requirements)  for qualifying for RIC  status
are determined at the Series level rather than at the Trust level.
    

   
    The  Code requires a RIC to pay a  nondeductible 4% excise tax to the extent
the RIC does  not distribute,  during each calendar  year, 98%  of its  ordinary
income,  determined on  a calendar  year basis,  and 98%  of its  capital gains,
determined, in general, on  an October 31 year  end, plus certain  undistributed
amounts from previous years. The required distributions, however, are based only
on  the taxable income of  a RIC. The excise  tax, therefore, generally will not
apply to  the  tax-exempt  income  of  a  RIC,  such  as  the  Fund,  that  pays
exempt-interest dividends.
    

   
    The  Trust intends to qualify the Fund to pay "exempt-interest dividends" as
defined in Section 852(b)(5) of the Code. Under such section if, at the close of
each quarter of the Fund's taxable year, at least 50% of the value of the Fund's
total assets consists of obligations exempt from Federal income tax ("tax-exempt
obligations")  under  Section  103(a)  of   the  Code  (relating  generally   to
obligations  of a state or local governmental unit), the Fund shall be qualified
to pay exempt-interest dividends to its Class  A, Class B, Class C, and Class  D
shareholders  (together,  the  "shareholders").  Exempt-interest  dividends  are
dividends or  any  part thereof  paid  by the  Fund  which are  attributable  to
interest   on   tax-exempt  obligations   and   designated  by   the   Trust  as
exempt-interest dividends in a written notice mailed to the Fund's  shareholders
within 60 days after the close of the Fund's taxable year. For this purpose, the
Trust  will allocate interest  from tax-exempt obligations  (as well as ordinary
income, capital gains and tax preference items discussed below) among the  Class
A,  Class B, Class C,  and Class D shareholders according  to a method (which it
believes is  consistent with  the Commission's  exemptive order  permitting  the
issuance  and sale  of multiple classes  of shares)  that is based  on the gross
income allocable to Class A, Class B,  Class C, and Class D shareholders  during
the  taxable  year or  such other  method  as the  Internal Revenue  Service may
prescribe.  To  the  extent  that  the  dividends  distributed  to  the   Fund's
shareholders  are derived  from interest income  exempt from  Federal income tax
under Code  Section  103(a)  and  are  properly  designated  as  exempt-interest
dividends, they will be excludable from a shareholder's gross income for Federal
income  tax  purposes.  Exempt-interest  dividends  are  included,  however,  in
determining the portion,  if any,  of a  person's social  security and  railroad
retirement  benefits subject to  Federal income taxes.  Interest on indebtedness
incurred or continued  to purchase or  carry Fund shares  is not deductible  for
Federal  income  tax  purposes or  Michigan  State  tax purposes  to  the extent
attributable to exempt-interest dividends.  Shareholders are advised to  consult
their
    

                                       43
<PAGE>
tax  advisers  with  respect  to whether  exempt-interest  dividends  retain the
exclusion under  Code Section  103(a) if  a shareholder  would be  treated as  a
"substantial user" or "related person" under Code Section 147(a) with respect to
property  financed  with the  proceeds of  an  issue of  "industrial development
bonds" or "private activity bonds," if any, held by the Fund.

   
    The portion of exempt-interest dividends paid from interest received by  the
Fund  from Michigan Municipal  Bonds also will be  exempt from Michigan personal
income tax  and  single  business  tax.  Additionally,  in  1986,  the  Michigan
Department  of Treasury issued  a Bulletin stating that  holders of interests in
regulated investment companies who are  subject to the Michigan intangibles  tax
will  be exempt  from the  tax to  the extent  that such  a company's investment
portfolio consists of items such as Michigan Municipal Bonds. Similarly,  shares
owned  by certain financial institutions or  by certain other persons subject to
the Michigan single  business tax are  not subject to  the Michigan  intangibles
tax.  Shareholders subject to income taxation  by states other than Michigan may
realize a lower after-tax  rate of return than  Michigan shareholders since  the
dividends  distributed by the Fund may not be exempt, to any significant degree,
from income taxation by  such other states. The  Trust will inform  shareholders
annually  as  to  the  portion of  the  Fund's  distributions  which constitutes
exempt-interest dividends and the portion  which is exempt from Michigan  income
taxes.  The Fund will allocate exempt-interest dividends among Class A, Class B,
Class C and Class  D shareholders for  Michigan income tax  purposes based on  a
method similar to that described above for Federal income tax purposes.
    

   
    To the extent that the Fund's distributions are derived from interest on its
taxable  investments or from an excess of  net short-term capital gains over net
long-term capital losses ("ordinary  income dividends"), such distributions  are
considered  ordinary income for  Federal and Michigan  income tax purposes. Such
distributions  are  not  eligible  for  the  dividends  received  deduction  for
corporations.  Distributions, if  any, of net  long-term capital  gains from the
sale of securities or from certain transactions in futures or options  ("capital
gain  dividends") are taxable as long-term  capital gains for Federal income tax
purposes, regardless of the length of time the shareholder has owned Fund shares
and, for Michigan income  tax purposes, are treated  as capital gains which  are
taxed as ordinary income. Under the Revenue Reconciliation Act of 1993, all or a
portion of the Fund's gain from the sale or redemption of tax-exempt obligations
purchased  at a market discount  will be treated as  ordinary income rather than
capital gain. This  rule may increase  the amount of  ordinary income  dividends
received by shareholders. Any loss upon the sale or exchange of Fund shares held
for  six months or less will be treated  as long-term capital loss to the extent
of any capital  gain dividends received  by the shareholder.  In addition,  such
loss  will be disallowed to the extent of any exempt-interest dividends received
by the shareholder. Distributions in excess  of the Fund's earnings and  profits
will  first reduce the adjusted  tax basis of a  holder's shares and, after such
adjusted tax basis  is reduced to  zero, will constitute  capital gains to  such
holder  (assuming the shares  are held as a  capital asset). If  the Fund pays a
dividend in January  which was  declared in  the previous  October, November  or
December  to shareholders of  record on a  specific date in  one of such months,
then such dividend will be  treated for tax purposes as  being paid by the  Fund
and  received  by its  shareholders on  December 31  of the  year in  which such
dividend was declared.
    

    The  Code  subjects  interest  received  on  certain  otherwise   tax-exempt
securities to an alternative minimum tax. The alternative minimum tax applies to
interest  received  on "private  activity bonds"  issued  after August  7, 1986.
Private activity  bonds  are bonds  which,  although tax-exempt,  are  used  for
purposes  other than those  generally performed by  governmental units and which
benefit non-governmental entities (e.g.,

                                       44
<PAGE>
   
bonds used for industrial development  or housing purposes). Income received  on
such  bonds is classified  as an item  of "tax preference,"  which could subject
investors in such bonds, including shareholders  of the Fund, to an  alternative
minimum tax. The Fund will purchase such "private activity bonds," and the Trust
will report to shareholders within 60 days after the Fund's taxable year-end the
portion  of the Fund's  dividends declared during the  year which constitutes an
item of tax preference  for alternative minimum tax  purposes. The Code  further
provides  that corporations are subject to  an alternative minimum tax based, in
part, on certain differences  between taxable income as  adjusted for other  tax
preferences  and  the  corporation's  "adjusted  current  earnings"  (which more
closely reflect  a corporation's  economic income).  Because an  exempt-interest
dividend  paid by  the Fund  will be  included in  adjusted current  earnings, a
corporate shareholder  may  be  required  to  pay  alternative  minimum  tax  on
exempt-interest dividends paid by the Fund.
    

    The  Revenue Reconciliation Act of 1993  has added new marginal tax brackets
of 36% and 39.6% for  individuals and has created  a graduated structure of  26%
and  28% for alternative  minimum tax applicable  to individual taxpayers. These
rate increases  may affect  an individual  investor's after-tax  return from  an
investment  in the  Fund as  compared with  such investor's  return from taxable
investments.

   
    No gain or loss will be recognized by Class B shareholders on the conversion
of their Class B shares into Class D shares. A shareholder's basis in the  Class
D  shares acquired will be  the same as such shareholder's  basis in the Class B
shares converted, and  the holding period  of the acquired  Class D shares  will
include the holding period for the converted Class B shares.
    

   
    If a shareholder exercises an exchange privilege within 90 days of acquiring
the  shares, then the loss the shareholder can recognize on the exchange will be
reduced (or the gain increased) to the extent the sales charge paid to the  Fund
reduces  any sales charge such shareholder would  have owed upon purchase of the
new shares in the absence of the exchange privilege. Instead, such sales  charge
will be treated as an amount paid for the new shares.
    

   
    A  loss  realized on  a  sale or  exchange  of shares  of  the Fund  will be
disallowed if  other Fund  shares are  acquired (whether  through the  automatic
reinvestment of dividends or otherwise) within a 61-day period beginning 30 days
before  and ending 30  days after the date  that the shares  are disposed of. In
such a case, the basis  of the shares acquired will  be adjusted to reflect  the
disallowed loss.
    

   
    Under  certain provisions of the Code, some shareholders may be subject to a
31% withholding tax  on certain ordinary  income dividends and  on capital  gain
dividends   and   redemption   payments   ("backup   withholding").   Generally,
shareholders subject to backup withholding will  be those for whom no  certified
taxpayer  identification number is on file with the Trust or who, to the Trust's
knowledge, have furnished an incorrect number. When establishing an account,  an
investor  must certify under penalty of perjury  that such number is correct and
that such investor is not otherwise subject to backup withholding.
    

    Ordinary  income  dividends  paid  by  the  Fund  to  shareholders  who  are
nonresident aliens or foreign entities will be subject to a 30% U.S. withholding
tax  under existing provisions of the Code applicable to foreign individuals and
entities unless a  reduced rate  of withholding  or a  withholding exemption  is
provided  under  applicable treaty  law. Nonresident  shareholders are  urged to
consult their  own  tax  advisers  concerning  the  applicability  of  the  U.S.
withholding tax.

                                       45
<PAGE>
    The  Code provides  that every  person required  to file  a tax  return must
include for information purposes  on such return  the amount of  exempt-interest
dividends  received from  all sources  (including the  Fund) during  the taxable
year.

ENVIRONMENTAL TAX

   
    The  Code  imposes  a  deductible   tax  (the  "Environmental  Tax")  on   a
corporation's  modified  alternative  minimum taxable  income  (computed without
regard to the alternative tax net operating loss deduction and the deduction for
the Environmental  Tax) at  a rate  of $12  per $10,000  (0.12%) of  alternative
minimum taxable income in excess of $2,000,000. The Environmental Tax is imposed
for taxable years beginning after December 31, 1986, and before January 1, 1996.
The  Environmental Tax is imposed even if the corporation is not required to pay
an  alternative  minimum  tax  because  the  corporation's  regular  income  tax
liability  exceeds its minimum tax liability. The Code provides, however, that a
RIC, such  as  the Fund,  is  not subject  to  the Environmental  Tax.  However,
exempt-interest  dividends  paid by  the  Fund that  create  alternative minimum
taxable income for corporate  shareholders under the  Code (as described  above)
may subject corporate shareholders of the Fund to the Environmental Tax.
    

TAX TREATMENT OF OPTION AND FUTURES TRANSACTIONS

   
    The  Fund may  purchase or sell  municipal bond index  futures contracts and
interest rate  futures  contracts  on  U.S.  Government  securities  ("financial
futures  contracts"). The Fund may also purchase  and write call and put options
on such financial futures contracts. In general, unless an election is available
to the  Fund  or  an  exception applies,  such  options  and  financial  futures
contracts  that  are "Section  1256 contracts"  will be  "marked to  market" for
Federal income tax purposes  at the end  of each taxable  year, i.e., each  such
option or financial futures contract will be treated as sold for its fair market
value  on  the  last  day  of  the taxable  year,  and  any  gain  or  loss from
transactions in options and  financial futures contracts  will be 60%  long-term
and  40% short-term capital gain or loss.  Application of these rules to Section
1256 contracts  held  by  the  Fund  may  alter  the  timing  and  character  of
distributions to shareholders.
    

   
    Code  Section 1092,  which applies  to certain  "straddles," may  affect the
taxation of the Fund's transactions  in financial futures contracts and  related
options.  Under Section 1092,  the Fund may be  required to postpone recognition
for tax purposes of losses incurred in certain closing transactions in financial
futures contracts or related options.
    

   
    One of the requirements for qualifications as a RIC is that less than 30% of
the Fund's gross income be derived from gains from the sale or other disposition
of securities held  for less  than three months.  Accordingly, the  Fund may  be
restricted  in effecting closing transactions within three months after entering
into an option or financial futures contract.
    
                              -------------------

    The foregoing  is  a  general  and abbreviated  summary  of  the  applicable
provisions  of the Code, Treasury regulations and Michigan tax laws presently in
effect. For the complete provisions, reference  should be made to the  pertinent
Code   sections,  the  Treasury  regulations   promulgated  thereunder  and  the
applicable Michigan tax laws. The Code and the Treasury regulations, as well  as
the  Michigan tax laws,  are subject to change  by legislative or administrative
action either prospectively or retroactively.

    Shareholders are  urged to  consult  their own  tax advisers  regarding  the
availability  of  any exemptions  from state  or local  taxes (other  than those
imposed by Michigan) and with specific questions as to Federal, state, local  or
foreign taxes.

                                PERFORMANCE DATA

   
    From  time to time the Fund may  include its average annual total return and
other total  return  data,  as  well  as  yield  and  tax-equivalent  yield,  in
advertisements  or information furnished to present or prospective shareholders.
Total return and yield and tax-equivalent yield figures are based on the  Fund's
historical  performance  and are  not intended  to indicate  future performance.
Average annual total  return and yield  are determined separately  for Class  A,
Class B, Class C and Class D shares in accordance with formulas specified by the
Commission.
    

   
    Average  annual  total  return  quotations  for  the  specified  periods are
computed by finding the average annual compounded rates of return (based on  net
investment  income and  any realized and  unrealized capital gains  or losses on
portfolio investments over such  periods) that would  equate the initial  amount
invested  to the redeemable value of such  investment at the end of each period.
Average annual total return is computed assuming all dividends and distributions
are reinvested and taking into account all applicable recurring and nonrecurring
expenses, including the maximum sales charge in the case of Class A and Class  D
shares  and the CDSC  that would be  applicable to a  complete redemption of the
investment at the end  of the specified period  in the case of  the Class B  and
Class C shares.
    

    The  Fund also may quote annual,  average annual and annualized total return
and aggregate  total return  performance data,  both as  a percentage  and as  a
dollar  amount based  on a hypothetical  $1,000 investment,  for various periods
other than those  noted below. Such  data will be  computed as described  above,
except  that (1) as  required by the  periods of the  quotations, actual annual,
annualized or aggregate data, rather than average annual data, may be quoted and
(2) the maximum applicable  sales charges will not  be included with respect  to
annual  or annualized rates of return calculations. Aside from the impact on the
performance data calculations of including  or excluding the maximum  applicable
sales  charges, actual annual or annualized  total return data generally will be
lower than average annual  total return data since  the average rates of  return
reflect  compounding of  return; aggregate total  return data  generally will be
higher than average annual total return data since the aggregate rates of return
reflect compounding over a longer period of time.

    In order to  reflect the reduced  sales charges in  the case of  Class A  or
Class  D shares, or  the waiver of  the CDSC in the  case of Class  B or Class C
shares applicable to certain investors, as described under "Purchase of  Shares"
and  "Redemption of Shares",  respectively, the total return  data quoted by the
Fund in advertisements  directed to  such investors  may take  into account  the
reduced, and not the maximum, sales charge or may take into account the CDSC and
therefore  may  reflect greater  total return  since, due  to the  reduced sales
charge or the waiver of sales charges, a lower amount of expenses is deducted.
    

                              GENERAL INFORMATION

DESCRIPTION OF SHARES

   
    The Declaration  of Trust  provides that  the Trust  shall be  comprised  of
separate  Series each of which  will consist of a  separate portfolio which will
issue separate shares.  The Trust is  presently comprised of  the Fund,  Merrill
Lynch  Arkansas Municipal Bond Fund, Merrill  Lynch Arizona Municipal Bond Fund,
Merrill Lynch Colorado Municipal Bond Fund, Merrill Lynch Connecticut  Municipal
Bond  Fund, Merrill  Lynch Florida Municipal  Bond Fund,  Merrill Lynch Maryland
Municipal Bond Fund,  Merrill Lynch Massachusetts  Municipal Bond Fund,  Merrill
Lynch  Minnesota Municipal  Bond Fund, Merrill  Lynch New  Jersey Municipal Bond
Fund, Merrill  Lynch New  Mexico Municipal  Bond Fund,  Merrill Lynch  New  York
Municipal Bond Fund,
    

                                       48
<PAGE>
   
Merrill  Lynch North Carolina Municipal Bond  Fund, Merrill Lynch Ohio Municipal
Bond Fund, Merrill Lynch Oregon Municipal Bond Fund, Merrill Lynch  Pennsylvania
Municipal  Bond Fund and  Merrill Lynch Texas Municipal  Bond Fund. The Trustees
are authorized to create an unlimited number of Series and, with respect to each
Series, to issue an unlimited number of full and fractional shares of beneficial
interest, par  value $.10  per share,  of  different classes  and to  divide  or
combine  the shares into  a greater or  lesser number of  shares without thereby
changing the  proportionate  beneficial  interests in  the  Series.  Shareholder
approval  is not necessary for the authorization of additional Series or classes
of a  Series  of  the  Trust.  At the  date  of  this  Statement  of  Additional
Information,  the shares of the Fund are divided into Class A, Class B, Class C,
and Class D shares. Both Class A, Class B, Class C, and Class D shares represent
an interest  in the  same assets  of the  Fund and  identical voting,  dividend,
liquidation  and other rights and the same  terms and conditions except that the
Class B,  Class C,  and Class  D shares  bear certain  expenses related  to  the
account maintenance and/or distribution of such shares and have exclusive voting
rights  with  respect to  matters relating  to  such account  maintenance and/or
distribution expenditures. The Trust  has received an  order (the "Order")  from
the  Commission permitting the issuance and  sale of multiple classes of shares.
The Order permits the Trust to issue additional classes of shares of any  Series
if  the Board of Trustees deems such issuance to be in the best interests of the
Trust.
    

   
    All shares of the Trust have equal voting rights, except that only shares of
the respective  Series are  entitled to  vote on  matters concerning  only  that
Series  and, as  noted above,  Class B, Class  C, and  Class D  shares will have
exclusive voting  rights  with  respect  to  matters  relating  to  the  account
maintenance  and/or distribution expenses being borne solely by such class. Each
issued and outstanding share is entitled to one vote and to participate  equally
in  dividends and distributions  declared by the  Fund and in  the net assets of
such Series  upon liquidation  or dissolution  remaining after  satisfaction  of
outstanding  liabilities, except that,  as noted above,  expenses related to the
account maintenance and/or  distribution of the  Class B, Class  C, and Class  D
shares  will be borne solely by such class. There normally will be no meeting of
shareholders for the purposes of electing Trustees unless and until such time as
less than  a  majority of  the  Trustees holding  office  have been  elected  by
shareholders,   at  which  time  the  Trustees   then  in  office  will  call  a
shareholders' meeting  for  the  election  of  Trustees.  Shareholders  may,  in
accordance  with  the terms  of the  Declaration  of Trust,  cause a  meeting of
shareholders to be held for  the purpose of voting  on the removal of  Trustees.
Also,  the Trust will be  required to call a  special meeting of shareholders in
accordance with  the  requirements of  the  1940 Act  to  seek approval  of  new
management  and advisory  arrangements, of  a material  increase in distribution
fees or of a change in the fundamental policies, objectives or restrictions of a
Series.
    

    The obligations and liabilities of a particular Series are restricted to the
assets of that Series and  do not extend to the  assets of the Trust  generally.
The  shares of each Series,  when issued, will be  fully paid and nonassessable,
have no preference, preemptive, conversion, exchange or similar rights, and  are
freely  transferable. Holders  of shares  of any  Series are  entitled to redeem
their shares as set forth elsewhere herein and in the Prospectus. Shares do  not
have  cumulative voting rights and the holders of more than 50% of the shares of
the Trust voting for the election of  Trustees can elect all of the Trustees  if
they choose to do so and in such event the holders of the remaining shares would
not  be able to elect any Trustees. No amendments may be made to the Declaration
of Trust without the affirmative vote of a majority of the outstanding shares of
the Trust.

    The Manager provided the initial capital  for the Fund by purchasing  10,000
shares  of the Fund for  $100,000. Such shares were  acquired for investment and
can only be disposed of by redemption. The

                                       49
<PAGE>
organizational expenses of  the Fund (estimated  at approximately $52,600)  were
paid  by the Fund and are amortized over  a period not exceeding five years. The
proceeds realized by the Manager (or any subsequent holder) upon the  redemption
of  any  of  the  shares  initially  purchased by  it  will  be  reduced  by the
proportionate amount of unamortized organizational expenses which the number  of
shares  redeemed  bears  to  the  number  of  shares  initially  purchased. Such
organizational expenses include certain  of the initial organizational  expenses
of  the  Trust  which  have been  allocated  to  the Fund  by  the  Trustees. If
additional Series are added  to the Trust, the  organizational expenses will  be
allocated among the Series in a manner deemed equitable by the Trustees.

COMPUTATION OF OFFERING PRICE PER SHARE

   
    An  illustration of the  computation of the  offering price for  Class A and
Class B shares  of the  Fund based on  the value  of the Fund's  net assets  and
number of shares outstanding on July 31, 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 offered  prior to the date  of this Statement of  Additional
Information.  The offering price for  Class B and Class C  shares of the Fund is
the net asset value of Class B and Class C shares, respectively.

                                   APPENDIX I
                 ECONOMIC AND FINANCIAL CONDITIONS IN MICHIGAN

    THE  INFORMATION SET  FORTH BELOW  IS DERIVED  FROM THE  OFFICIAL STATEMENTS
PREPARED IN CONNECTION WITH THE ISSUANCE  OF MICHIGAN MUNICIPAL BONDS AND  OTHER
SOURCES  THAT ARE GENERALLY AVAILABLE TO  INVESTORS. THE INFORMATION IS PROVIDED
AS GENERAL INFORMATION INTENDED TO GIVE  A RECENT HISTORICAL DESCRIPTION AND  IS
NOT  INTENDED TO INDICATE FUTURE OR CONTINUING  TRENDS IN THE FINANCIAL OR OTHER
POSITIONS OF THE  STATE OF MICHIGAN.  THE TRUST HAS  NOT INDEPENDENTLY  VERIFIED
THIS INFORMATION.

   
    Due  primarily to  the fact that  the leading  sector of the  economy of the
State of Michigan (sometimes referred to as the "State") is the manufacturing of
durable goods, economic  activity in the  State has tended  to be more  cyclical
than  in  the nation  as a  whole. While  the State's  efforts to  diversify its
economy have  proven successful,  as reflected  by the  fact that  the share  of
employment  in the State  in the durable  goods sector has  fallen from 33.1% in
1960 to 17.3% in  1991, durable goods manufacturing  still represents a  sizable
portion  of the State's economy. As  a result, any substantial national economic
downturn is likely to have an adverse effect on the economy of the State and  on
the revenues of the State and some of its local governmental units. Recently, as
well  as historically,  the average monthly  unemployment rate in  the State has
been higher than the average figures for the United States.
    

   
    The State's economy  could continue to  be affected by  changes in the  auto
industry,  notably consolidation  and plant closings  resulting from competitive
pressures and overcapacity. Such actions  could adversely affect State  revenues
and  the financial impact on the local units of government in the areas in which
plants are closed could be more severe. The impact on the financial condition of
the municipalities in which the plants are  located may be more severe than  the
impact on the State itself.
    

    The  Michigan Constitution limits the amount  of total revenues of the State
raised from taxes  and certain other  sources to  a level for  each fiscal  year
equal  to a  percentage of  the State's personal  income for  the prior calendar
year. In the event the  State's total revenues exceed the  limit by 1% or  more,
the  Constitution requires that  the excess be refunded  to taxpayers. The State
Constitution does not prohibit the increasing  of taxes so long as revenues  are
expected  to amount to less than the  revenue limit and authorizes exceeding the
limit  for  emergencies.  The  State  Constitution  further  provides  that  the
proportion  of State spending paid to all local units' total spending may not be
reduced below  the  proportion  in  effect for  the  1978-79  fiscal  year.  The
Constitution  requires that if  spending does not  meet the required  level in a
given year  an additional  appropriation for  local units  is required  for  the
following fiscal year. The State Constitution also requires the State to finance
any  new  or  expanded  activity  of local  units  mandated  by  State  law. Any
expenditures required by this provision would  be counted as State spending  for
local  units for purposes  of determining compliance  with the provisions stated
above.

    The  State  Constitution  limits  the  purposes  for  which  State   general
obligation debt may be issued. Such debt is limited to short-term debt for State
operating purposes, short-and long-term debt for the purposes of making loans to
school  districts and long-term debt for voter approved purposes. In addition to
the foregoing, the State authorizes special purpose agencies and authorities  to
issue revenue bonds payable from designated revenues and fees. Revenue bonds are
not  obligations of the State and in  the event of shortfalls in self-supporting
revenues, the State has no legal  obligation to appropriate money to these  debt
service  payments. The State's Constitution also directs or restricts the use of
certain revenues.

                                       52
<PAGE>
    The State  finances its  operations  through the  State's General  Fund  and
Special  Revenue Funds. The General Fund receives revenues of the State that are
not specifically required to  be included in the  Special Revenue Fund.  General
Fund revenues are obtained approximately 63% from the payment of State taxes and
37%  from federal and non-tax revenue sources. The majority of the revenues from
State taxes are from the State's  personal income tax, single business tax,  use
tax,  sales tax and various other taxes. Approximately 60% of total General Fund
expenditures are for State support of  public education and for social  services
programs. Other significant expenditures from the General Fund provide funds for
law  enforcement, general State government, debt service and capital outlay. The
State Constitution requires that any prior year's surplus or deficit in any fund
must be included in the next succeeding year's budget for that fund.

   
    In recent years, the State of Michigan has reported its financial results in
accordance with generally accepted accounting  principles. For the fiscal  years
ended  September 30, 1990 and 1991, the State reported negative year-end General
Fund balances of $310.4 million and $169.4 million, respectively, but ended  the
1992  fiscal year with its  General Fund in balance.  A positive cash balance in
the combined General Fund/ School Aid  Fund was recorded at September 30,  1990.
In  each of the three  fiscal years ending with  the fiscal year ended September
30, 1993, the  State undertook  mid-year actions to  address projected  year-end
budget  deficits. From  1991 through  1993, the  State experienced deteriorating
cash balances  which  necessitated short-term  borrowings  and the  deferral  of
certain scheduled cash payments of local units of government. The State borrowed
$700  million for cash flow purposes in the 1992 fiscal year and $900 million in
the 1993 fiscal year.  The State has  a Budget Stabilization  Fund which had  an
accrued  balance  of $20.1  million as  of  September 30,  1992, and,  after the
transfer of $283  million on  an accrual basis  upon completion  of the  State's
financial reports, an ending balance of $303 million as of September 30, 1993.
    

   
    Amendments   to  the  Michigan  Constitution  which  placed  limitations  on
increases in State  taxes and local  ad valorem taxes  (including taxes used  to
meet  debt service commitments on obligations  of taxing units) were approved by
the voters of the State  of Michigan in November,  1978 and became effective  on
December  23, 1978. To the extent that obligations in the Fund are tax supported
and are for local units and have  not been voted by the taxing unit's  electors,
the ability of the local units to levy debt service taxes might be affected.
    

   
    State  law provides  for distributions of  certain State  collected taxes or
portions thereof to local units based in  part on population as shown by  census
figures  and authorizes  levy of  certain local  taxes by  local units  having a
certain level  of population  as  determined by  census figures.  Reductions  in
population  in  local units  resulting from  periodic census  could result  in a
reduction in the amount of State  collected taxes returned to those local  units
and in reductions in levels of local tax collections for such local units unless
the impact of the census is changed by State law. No assurance can be given that
any  such State law will be enacted. In the 1991 fiscal year, the State deferred
certain scheduled payments to municipalities, school districts, universities and
community colleges. While such  deferrals were made up  at later dates,  similar
future deferrals could have an adverse impact on the cash position of some local
units.   Additionally,  the  State  has  reduced  revenue  sharing  payments  to
municipalities below the level provided under formulas by increasing amounts  in
the  three fiscal years ending with the fiscal year ended September 30, 1993 and
$64.6 million (budgeted) in the fiscal year which ended on September 30, 1994.
    

   
    On March 15,  1994, the electors  of the  State voted to  amend the  State's
Constitution  to increase the State sales tax rate from 4% to 6% and to place an
annual cap on property  assessment increases for  all property taxes.  Companion
legislation also cut the State's income tax rate from 4.6% to 4.4%. In addition,
    

                                       53
<PAGE>
   
property  taxes  for  school operating  purposes  have been  reduced  and school
funding is  being  provided from  a  combination  of property  taxes  and  state
revenues,  some of which are  being provided from new  or increased State taxes.
The legislation also  contains other  provisions that  may reduce  or alter  the
revenues  of  local  units  of  government  and  tax  increment  bonds  could be
particularly affected. While the ultimate impact of the constitutional amendment
and related legislation cannot yet be accurately predicted, investors should  be
alert  to the potential effect of such measures upon the operations and revenues
of Michigan local units of government.
    

   
    Currently, the  State's general  obligation bonds  are rated  A1 by  Moody's
Investors  Service, Inc., AA  by Standard &  Poor's Corporation and  AA by Fitch
Investors Service, Inc.

                           RATINGS OF MUNICIPAL BONDS

DESCRIPTION OF MOODY'S INVESTORS SERVICE, INC.'S ("MOODY'S") MUNICIPAL BOND
RATING

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

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

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

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

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

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

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

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

C          Bonds which are rated C are the lowest rated class of bonds, and issues so rated can
           be regarded as having extremely poor prospects of ever attaining any real investment
           standing.
<FN>

NOTE:  Those bonds  in the Aa,  A, Baa, Ba  and B groups  which Moody's believes
possess the strongest investment attributes  are designated by the symbols  Aa1,
A1, Baa1, Ba1 and B1.

    SHORT-TERM  NOTES: The four ratings of  Moody's for short-term notes are MIG
1/VMIG1, MIG 2/VMIG2,  MIG 3/VMIG3 and  MIG 4/VMIG4; MIG  1/VMIG1 denotes  "best
quality...strong  protection  by established  cash  flows"; MIG  2/VMIG2 denotes
"high quality"  with ample  margins  of protection;  MIG  3/VMIG3 notes  are  of
"favorable  quality...but...lacking  the  undeniable strength  of  the preceding
grades"; MIG  4/VMIG4 notes  are  of "adequate  quality...[p]rotection  commonly
regarded as required of an
investment security is present...there is specific risk."

DESCRIPTION OF MOODY'S CORPORATE BOND RATINGS

   
    Excerpts from Moody's description of its corporate bond ratings: Aaa--judged
to be the best quality, carry the smallest degree of investment risk; Aa--judged
to  be of  high quality by  all standards; A--possess  many favorable investment
attributes and are  to be considered  as upper medium  grade obligations;  Baa--
considered  as medium grade obligations, i.e., they are neither highly protected
or poorly secured.
    

DESCRIPTION OF MOODY'S COMMERCIAL PAPER RATINGS

    Moody's Commercial Paper ratings are opinions  of the ability of issuers  to
repay  punctually  promissory obligations  not  having an  original  maturity in
excess of nine  months. Moody's  employs the following  three designations,  all
judged  to be investment  grade, to indicate the  relative repayment capacity of
rated issuers:

    Issuers rated Prime-1 (or related  supporting institutions) have a  superior
capacity  for repayment of short-term  promissory obligations. Prime-1 repayment
capacity will normally  be evidenced by  the following characteristics:  leading
market  positions in well established industries;  high rates of return on funds
employed; conservative capitalization structures with moderate reliance on  debt
and ample asset protection; broad margins in earning coverage of fixed financial
charges  and high  internal cash  generation; and  well established  access to a
range of financial markets and assured sources of alternate liquidity.

    Issuers rated Prime-2  (or related  supporting institutions)  have a  strong
capacity  for repayment of short-term promissory obligations. This will normally
be evidenced by many of the characteristics cited above but to a lesser  degree.
Earnings  trends  and coverage  ratios,  while sound,  will  be more  subject to
variation. Capitalization characteristics, while still appropriate, may be  more
affected by external conditions. Ample alternate liquidity is maintained.

    Issuers   rated  Prime-3  (or  related   supporting  institutions)  have  an
acceptable capacity  for repayment  of  short-term promissory  obligations.  The
effects   of  industry  characteristics  and  market  composition  may  be  more
pronounced. Variability in earnings and  profitability may result in changes  in
the  level of  debt protection measurements  and the  requirement for relatively
high financial leverage. Adequate alternate liquidity is maintained.

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

DESCRIPTION OF STANDARD & POOR'S CORPORATION'S ("STANDARD & POOR'S") MUNICIPAL
DEBT RATINGS

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

    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.

                                       56
<PAGE>
    The  ratings are  based on  current information  furnished by  the issuer or
obtained by Standard  & Poor's from  other sources Standard  & Poor's  considers
reliable.  Standard & Poor's  does not perform  an audit in  connection with any
rating and  may,  on occasion,  rely  on unaudited  financial  information.  The
ratings  may be changed,  suspended or withdrawn  as a result  of changes in, or
unavailability of, such information, or for other circumstances.

    The ratings are based, in varying degrees, on the following considerations:

   
<TABLE>
<S>        <C>
I.         Likelihood of default -- capacity and willingness of the obligor as to the  timely
           payment of interest and repayment of principal in accordance with the terms of the
           obligation;
II.        Nature of and provisions of the obligations;
III.       Protection  afforded by, and relative position of,  the obligation in the event of
           bankruptcy, reorganization or other arrangement  under the laws of bankruptcy  and
           other laws affecting creditors' rights.
AAA        Debt rated "AAA" has the highest rating assigned by Standard & Poor's. Capacity to
           pay interest and repay principal is extremely strong.
AA         Debt rated "AA" has a very strong capacity to pay interest and repay principal and
           differs from the higher-rated issues only in small degree.
A          Debt  rated "A" has a strong capacity to pay interest and repay principal although
           it is somewhat more susceptible to the adverse effects of changes in circumstances
           and economic conditions than debt in higher-rated categories.
BBB        Debt rated "BBB" is regarded  as having an adequate  capacity to pay interest  and
           repay  principal.  Whereas it  normally  exhibits adequate  protection parameters,
           adverse economic conditions or changing circumstances are more likely to lead to a
           weakened capacity to pay  interest and repay principal  for debt in this  category
           than for debt in higher rated categories.
BB         Debt   rated  "BB",  "B",  "CCC",  "CC"  and  "C"  is  regarded,  on  balance,  as
B          predominately speculative  with respect  to  capacity to  pay interest  and  repay
CCC        principal  in accordance  with the  terms of  the obligations.  "BB" indicates the
CC         lowest degree of  speculation and "CC"  the highest degree  of speculation.  While
C          such  debt will likely have some quality and protective characteristics, these are
           outweighed by large uncertainties or major exposures to adverse conditions.
CI         The rating "C" is reserved for income bonds on which no interest is being paid.
D          Debt rated  "D" is  in  payment default.  The "D"  rating  category is  used  when
           interest  payments or principal payments are not made  on the date due even if the
           applicable grace period has  not expired, unless Standard  & Poor's believes  that
           such  payments will be made during such grace  period. The "D" rating also will be
           used upon  the  filing of  a  bankruptcy petition  if  debt service  payments  are
           jeopardized.
</TABLE>
    

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

DESCRIPTION OF STANDARD & POOR'S CORPORATE BOND RATINGS

    A Standard &  Poor's corporate debt  rating is a  current assessment of  the
creditworthiness  of an obligor with respect  to specific obligation. Debt rated
"AAA" has the  highest rating  assigned by Standard  & Poor's.  Capacity to  pay
interest  and repay principal  is extremely strong.  Debt rated "AA"  has a very
strong capacity to  pay interest  and to repay  principal and  differs from  the
highest  rated issues only in small degree. Debt rated "A" has a strong capacity
to pay interest and repay principal although it is somewhat more susceptible  to
the  adverse effects  of changes in  circumstances and  economic conditions than
debt of a  higher rated  category. Debt  rated "BBB"  is regarded  as having  an
adequate  capacity  to pay  interest and  repay  principal. Whereas  it normally
exhibits adequate protection parameters, adverse economic conditions or changing
circumstances are more likely to lead to a weakened capacity to pay interest and
repay principal for debt in this category than in higher rated categories.

    The ratings from "AA" to "BBB" may be modified by the addition of a plus  or
minus sign to show relative standing within the major rating categories.

DESCRIPTION OF STANDARD & POOR'S COMMERCIAL PAPER RATINGS

    A  Standard & Poor's Commercial Paper Rating  is a current assessment of the
likelihood of timely payment of debt having an original maturity of no more than
365 days. Ratings  are graded  into four categories,  ranging from  "A" for  the
highest  quality obligations  to "D" for  the lowest. Ratings  are applicable to
both taxable and tax-exempt commercial paper. Issues assigned the highest rating
are regarded as having the greatest capacity for timely payment. Issues in  this
category  are further refined  with the designation  1, 2 and  3 to indicate the
relative degree of  safety. The three  designations in the  "A" category are  as
follows:

<TABLE>
<C>        <S>
      A-1  This  designation indicates that the degree  of safety regarding timely payment is
           either overwhelming or very strong.  Those issues determined to possess  extremely
           strong safety characteristics are denoted with a plus sign (+) designation.
      A-2  Capacity  for timely payment  on issues with this  designation is strong. However,
           the relative degree  of safety  is not as  overwhelming 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  speculative capacity  for timely
           payment.
        C  This rating is assigned  to short-term debt obligations  with a doubtful  capacity
           for payment.
        D  Debt  rated  "D" is  in  payment default.  The "D"  rating  category is  used when
           interest payments or principal payments are not made on the date due, even if  the
           applicable  grace period has  not expired, unless S&P  believes that such payments
           will be made during such grace period.
</TABLE>

    A Commercial Paper  Rating is  not a recommendation  to purchase  or sell  a
security.  The ratings are based on  current information furnished to Standard &
Poor's by the issuer  and 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.

                                       58
<PAGE>
    A Standard & Poor's note rating  reflects the liquidity concerns and  market
access risks unique to notes. Notes due in 3 years or less will likely receive a
note  rating. Notes maturing beyond 3 years will most likely receive a long-term
debt rating. The following criteria will be used in making that assessment.

    --Amortization schedule (the  larger the  final maturity  relative to  other
      maturities, the more likely it will be treated as a note).

    --Source  of payment (the more dependent the  issue is on the market for its
      refinancing, the more likely it will be treated as a note).

    Note rating symbols are as follows:

    SP-1  A very strong or strong capacity to pay principal and interest.  Those
          issues  determined to possess overwhelming safety characteristics will
          be given a "+" designation.

    SP-2  A satisfactory capacity to pay principal and interest.

    SP-3  A speculative capacity to pay principal and interest.

    Standard & Poor's may continue to  rate note issues with a maturity  greater
than three years in accordance with the same rating scale currently employed for
municipal bond ratings.

    UNRATED:  Where  no rating  has been  assigned  or where  a rating  has been
suspended or withdrawn, it may  be for reasons unrelated  to the quality of  the
issue.

    Should no rating be assigned, the reason may be one of the following:

       1. An application for rating was not received or accepted.

       2. The  issue or issuers  belongs to a  group of securities  that are not
          rated as a matter of policy.

       3. There is a lack of essential data pertaining to the issue or issuer.

       4. The issue  was privately  placed,  in which  case  the rating  is  not
          published in Moody's publications.

    Suspension  or withdrawal may occur if new and material circumstances arise,
    the effects of which preclude satisfactory  analysis; if there is no  longer
    available  reasonable  up-to-date information  to  permit a  judgment  to be
    formed; if a bond is called for redemption; or for other reasons.

DESCRIPTION OF FITCH INVESTORS SERVICE, INC.'S ("FITCH") INVESTMENT GRADE BOND
RATINGS

    Fitch investment  grade  bond  ratings  provide  a  guide  to  investors  in
determining  the credit risk associated with  a particular security. The ratings
represent Fitch's assessment of the issuer's ability to meet the obligations  of
a specific debt issue or class of debt in a timely manner.

    The  rating  takes into  consideration special  features  of the  issue, its
relationship to other  obligations of  the issuer, the  current and  prospective
financial  condition  and  operating  performance  of  the  issuer  and  of  any
guarantor, as well as the economic  and political environment that might  affect
the issuer's future financial strength and credit quality.

    Fitch  ratings do not reflect any credit enhancement that may be provided by
insurance policies or financial guaranties unless otherwise indicated.

                                       59
<PAGE>
    Bonds that have the same rating are of similar but not necessarily identical
credit  quality  since  the  rating  categories  do  not  fully  reflect   small
differences in the degrees of credit risk.

    Fitch  ratings are not  recommendations to buy, sell,  or hold any security.
Ratings do not comment on the adequacy  of market price, the suitability of  any
security  for a particular  investor, or the tax-exempt  nature or taxability of
payments made in respect of any security.

    Fitch  ratings  are  based  on  information  obtained  from  issuers,  other
obligors,  underwriters, their experts,  and other sources  Fitch believes to be
reliable. Fitch  does  not  audit  or  verify the  truth  or  accuracy  of  such
information.  Ratings may  be changed,  suspended, or  withdrawn as  a result of
changes in, or the unavailability of, information or for any other reasons.

<TABLE>
<S>        <C>
AAA        Bonds considered  to be  investment grade  and of  the highest  credit quality.  The
           obligor  has an  exceptionally strong ability  to pay interest  and repay principal,
           which is unlikely to be affected by reasonably foreseeable events.

AA         Bonds considered  to  be investment  grade  and of  very  high credit  quality.  The
           obligor's  ability to pay interest and repay  principal is very strong, although not
           quite as strong  as bonds rated  "AAA". Because bonds  rated in the  "AAA" and  "AA"
           categories  are  not significantly  vulnerable  to foreseeable  future developments,
           short-term debt of these issuers is generally rated "F-1+".

A          Bonds considered to be  investment grade and of  high credit quality. The  obligor's
           ability  to pay interest and repay principal is  considered to be strong, but may be
           more vulnerable to  adverse changes  in economic conditions  and circumstances  than
           bonds with higher ratings.

BBB        Bonds  considered to  be investment  grade and  of satisfactory  credit quality. The
           obligor's ability to pay interest and repay principal is considered to be  adequate.
           Adverse  changes in economic conditions and  circumstances, however, are more likely
           to have adverse  impact on these  bonds, and therefore,  impair timely payment.  The
           likelihood  that the  ratings of  these bonds  will fall  below investment  grade is
           higher than for bonds with higher ratings.
</TABLE>

    Plus (+) or Minus (-): Plus and minus signs are used with a rating symbol to
indicate the relative position of a credit within the rating category. Plus  and
minus signs, however, are not used in the "AAA" category.

    Credit   Trend  Indicator:  Credit  trend  indicators  show  whether  credit
fundamentals are improving, stable, declining, or uncertain, as follows:

Improving      Up arrow
Stable         Arrow to left followed by arrow to right
Declining      Down arrow
Uncertain      Up arrow above down arrow

                                       60
<PAGE>
Credit trend indicators are not predictions  that any rating change will  occur,
and have a longer-term time frame than issues placed on FitchAlert.

<TABLE>
<S>               <C>
NR                Indicates that Fitch does not rate the specific issue.
Conditional       A conditional rating is premised on the successful completion of a project
                  or the occurrence of a specific event.
Suspended         A rating is suspended when Fitch deems the amount of information available
                  from the issuer to be inadequate for rating purposes.
Withdrawn         A  rating  will  be  withdrawn  when an  issue  matures  or  is  called or
                  refinanced and, at  Fitch's discretion,  when an issuer  fails to  furnish
                  proper and timely information.
FitchAlert        Ratings are placed on FitchAlert to notify investors of an occurrence that
                  is  likely to result in  a rating change and  the likely direction of such
                  change.  These  are  designated  as  "Positive,"  indicating  a  potential
                  upgrade, "Negative," for potential downgrade, or "Evolving," where ratings
                  may  be raised or lowered. FitchAlert is relatively short-term, and should
                  be resolved within 12 months.
</TABLE>

DESCRIPTION OF FITCH SPECULATIVE GRADE BOND RATINGS

    Fitch speculative  grade  bond  ratings  provide a  guide  to  investors  in
determining  the credit risk associated with  a particular security. The ratings
("BB" to "C") represent Fitch's assessment  of the likelihood of timely  payment
of  principal and interest in  accordance with the terms  of obligation for bond
issues not in  default. For defaulted  bonds, the  rating ("DDD" to  "D") is  an
assessment of the ultimate recovery value through reorganization or liquidation.

    The  rating  takes into  consideration special  features  of the  issue, its
relationship to other  obligations of  the issuer, the  current and  prospective
financial  condition and operating performance of  the issuer and any guarantor,
as well as the economic and political environment that might affect the issuer's
future financial strength.

    Bonds that have the same rating are of similar but not necessarily identical
credit quality since rating categories  cannot fully reflect the differences  in
degrees of credit risk.

<TABLE>
<S>                 <C>
BB                  Bonds  are considered speculative. The obligor's ability to pay interest
                    and repay  principal  may be  affected  over time  by  adverse  economic
                    changes.  However, business and financial alternatives can be identified
                    which  could  assist  the  obligor   in  satisfying  its  debt   service
                    requirements.
B                   Bonds  are considered highly speculative. While  bonds in this class are
                    currently  meeting  debt  service   requirements,  the  probability   of
                    continued   timely  payment  of  principal  and  interest  reflects  the
                    obligor's limited margin of safety and the need for reasonable  business
                    and economic activity throughout the life of the issue.
CCC                 Bonds  have certain identifiable characteristics which, if not remedied,
                    may lead  to  default.  The  ability to  meet  obligations  requires  an
                    advantageous business and economic environment.

<S>                 <C>
CC                  Bonds  are minimally  protected. Default  in payment  of interest and/or
                    principal seems probable over time.
C                   Bonds are in imminent default in payment of interest or principal.
DDD DD and D        Bonds are in default on  interest and/or principal payments. Such  bonds
                    are  extremely speculative  and should be  valued on the  basis of their
                    ultimate recovery value in liquidation or reorganization of the obligor.
                    "DDD" represents the highest potential for recovery on these bonds,  and
                    "D" represents the lowest potential for recovery.

    Plus (+) or Minus (-): Plus and minus signs are used with a rating symbol to
indicate  the relative position of a credit within the rating category. Plus and
minus signs, however, are not used in the "DDD", "DD", or "D" categories.

DESCRIPTION OF FITCH INVESTMENT GRADE SHORT-TERM RATINGS

    Fitch's short-term ratings  apply to  debt obligations that  are payable  on
demand  or have  original maturities of  generally up to  three years, including
commercial paper, certificates of deposit, medium-term notes, and municipal  and
investment notes.

    The short-term rating places greater emphasis than a long-term rating on the
existence  of liquidity necessary  to meet the issuer's  obligations in a timely
manner.

    Fitch short-term ratings are as follows:

   
<TABLE>
<S>                 <C>
F-1+                Exceptionally Strong  Credit Quality.  Issues assigned  this rating  are
                    regarded as having the strongest degree of assurance for timely payment.
F-1                 Very  Strong  Credit Quality.  Issues  assigned this  rating  reflect an
                    assurance of timely  payment only  slightly less in  degree than  issues
                    rated "F-1+".
F-2                 Good  Credit Quality.  Issues assigned  this rating  have a satisfactory
                    degree of assurance for timely payment, but the margin of safety is  not
                    as great as for issues assigned "F-1+" and "F-1" ratings.
F-3                 Fair  Credit Quality.  Issues assigned this  rating have characteristics
                    suggesting that the degree of assurance for timely payment is  adequate,
                    however,  near-term adverse changes  could cause these  securities to be
                    rated below investment grade.
F-S                 Weak Credit Quality.  Issues assigned this  rating have  characteristics
                    suggesting  a minimal  degree of  assurance for  timely payment  and are
                    vulnerable to  near-term  adverse  changes  in  financial  and  economic
                    conditions.
D                   Default.  Issues assigned this rating are  in actual or imminent payment
                    default.
LOC                 The symbol  "LOC" indicates  that the  rating is  based on  a letter  of
                    credit issued by a commercial bank.

INDEPENDENT AUDITORS' REPORT

The Board of Trustees and Shareholders,
MERRILL LYNCH MICHIGAN MUNICIPAL BOND FUND OF
MERRILL LYNCH MULTI-STATE MUNICIPAL SERIES TRUST:

   
We  have audited the accompanying statement of assets and liabilities, including
the schedule of investments,  of Merrill Lynch Michigan  Municipal Bond Fund  of
Merrill  Lynch  Multi-State Municipal  Series  Trust as  of  July 31,  1994, the
related statements of  operations for  the year then  ended and  changes in  net
assets for the year then ended and for the period January 29, 1993 (commencement
of  operations) to July 31, 1993, and the financial highlights for the year then
ended and for the period January  29, 1993 (commencement of operations) to  July
31,  1993.  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 July 31,
1994  by correspondence with the custodian. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. We believe that  our
audits provide a reasonable basis for our opinion.
    

   
In  our  opinion, such  financial  statements and  financial  highlights present
fairly, in  all  material respects,  the  financial position  of  Merrill  Lynch
Michigan Municipal Bond Fund of Merrill Lynch Multi-State Municipal Series Trust
as  of July  31, 1994,  the results of  its operations,  the changes  in its net
assets, and  the  financial highlights  for  the respective  stated  periods  in
conformity with generally accepted accounting principles.

NOTES TO FINANCIAL STATEMENTS


1.   Significant Accounting Policies:
Merrill Lynch Michigan Municipal Bond Fund (the "Fund") is part of Merrill Lynch
Multi-State Municipal Series Trust (the "Trust"). The Fund is registered under
the Investment Company Act of 1940 as a non-diversified, open-end management
investment company. The Fund offers both 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--Municipal bonds and other portfolio securities in
which the Fund invests are traded primarily in the over-the-counter municipal
bond and money markets and are valued at the last available bid price in the
over-the-counter market or on the basis of yield equivalents as obtained from
one or more dealers that make markets in the securities. Financial futures
contracts and options thereon, which are traded on exchanges, are valued at
their settlement prices as of the close of such exchanges. Short-term
investments with remaining maturities of sixty days or less are valued at
amortized cost, which approximates market value. 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. Securities and assets
for which market quotations are not readily available are valued at fair value
as determined in good faith by or under the direction of the Board of Trustees
of the Trust, including valuations furnished by a pricing service retained by
the Trust, which may utilize a matrix system for valuations. The procedures of
the pricing service and its valuations are reviewed by the officers of the Trust
under the general supervision of the Trustees.

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

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

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

(e)  Deferred organization expenses and prepaid registration fees--Deferred
organization expenses

                                       71

<PAGE>

are charged to expense on a straight-line basis over a five-year period. Prepaid
registration fees are charged to expense as the related shares are issued.

(f)  Dividends and distributions--Dividends from net investment income are
declared daily and paid monthly. Distributions of capital gains are recorded on
the ex-dividend dates. Distributions in excess of realized capital gains are due
primarily to differing tax treatments for futures transactions and post October
losses.

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

FAM is responsible for the management of the Fund's portfolio and provides the
necessary personnel, facilities, equipment and certain other services necessary
to the operations of the Fund. For such services, the Fund pays a monthly fee
based upon the average daily value of the Fund's net assets at the following
annual rates: 0.55% of the Fund's average daily net assets not exceeding $500
million; 0.525% of average daily net assets in excess of $500 million but not
exceeding $1 billion; and 0.50% of average daily net assets in excess of $1
billion. For the year ended July 31, 1994, FAM earned fees of $383,179, all of
which was voluntarily waived. FAM also voluntarily reimbursed the Fund
additional expenses of $102,130.

Pursuant to a distribution plan (the "Distribution Plan") adopted by the Fund in
accordance with Rule 12b-1 under the Investment Company Act of 1940, the Fund
pays the Distributor an ongoing account maintenance fee and distribution fee
relating to Class B Shares, which are accrued daily and paid monthly at the
annual rates of 0.25% and 0.25%, respectively, of the average daily net assets
of the Class B Shares of the Fund. Pursuant to a sub-agreement with the
Distributor, Merrill Lynch, Pierce Fenner & Smith Inc. ("MLPF&S"), an affiliate
of ML & Co., also provides account maintenance and distribution services to the
Fund. The ongoing distribution and account maintenance fees compensate the
Distributor and MLPF&S for providing distribution and account maintenance
services to Class B shareholders. As authorized by the Plan, the Distributor has
entered into an agreement with MLPF&S which provides for the compensation of
MLPF&S for providing distribution-related services to the Fund. For the year
ended July 31, 1994, MLFD earned underwriting discounts of $7,508, and MLPF&S
earned dealer concessions of $50,077 on sales of the Fund's Class A Shares.

MLPF&S also received contingent deferred sales charges of $100,415 relating to
Class B Share transactions during the year.

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

ITEM 27.  INDEMNIFICATION.

    Section 5.3 of the Registrant's Declaration of Trust provides as follows:

    "The Trust shall  indemnify each  of its Trustees,  officers, employees  and
agents  (including persons  who serve at  its request as  directors, officers or
trustees of another organization in which it has any interest as a  shareholder,
creditor  or otherwise) against all  liabilities and expenses (including amounts
paid in satisfaction of judgments, in compromise, as fines and penalties and  as
counsel  fees)  reasonably incurred  by him  in connection  with the  defense or
disposition of any action, suit or other proceeding, whether civil or  criminal,
in  which he may be involved or with which he may be threatened, while in office
or thereafter, by reason of  his being or having  been such a trustee,  officer,
employee  or agent, except with respect to any  matter as to which he shall have
been adjudicated  to  have  acted  in  bad  faith,  willful  misfeasance,  gross
negligence  or reckless disregard  of his duties; provided,  however, that as to
any matter disposed of  by a compromise  payment by such  person, pursuant to  a
consent  decree or otherwise, no indemnification  either for said payment or for
any other expenses  shall be  provided unless the  Trust shall  have received  a
written  opinion from independent legal counsel  approved by the Trustees to the
effect that if  either the matter  of willful misfeasance,  gross negligence  or
reckless disregard of duty, or the matter of good faith and reasonable belief as
to  the best interests  of the Trust,  had been adjudicated,  it would have been
adjudicated in favor  of such person.  The rights accruing  to any Person  under
these  provisions shall not exclude any other  right to which he may be lawfully
entitled; provided  that  no  person  may satisfy  any  right  in  indemnity  or
reimbursement  granted herein or in Section 5.1  or to which he may be otherwise
entitled except out of the  property of the Trust,  and no Shareholder shall  be
personally  liable to  any Person  with respect  to any  claim for  indemnity or
reimbursement or otherwise. The Trustees may make advance payments in connection
with indemnification  under  this Section  5.3,  provided that  the  indemnified
person  shall have  given a  written undertaking to  reimburse the  Trust in the
event  it  is  subsequently  determined  that   he  is  not  entitled  to   such
indemnification."

    Insofar  as the conditional advancing  of indemnification monies for actions
based upon the  Investment Company Act  of 1940, as  amended, may be  concerned,
such  payments will be made  only on the following  conditions: (i) the advances
must be  limited  to  amounts used,  or  to  be used,  for  the  preparation  or
presentation  of a  defense to  the action,  including costs  connected with the
preparation of a settlement; (ii)  advances may be made  only upon receipt of  a
written  promise by, or on behalf of, the  recipient to repay that amount of the
advance which exceeds the amount to which it is ultimately determined that he is
entitled to receive from the Registrant by reason of indemnification; and  (iii)
(a)  such promise must be secured by  a surety bond, other suitable insurance or
an equivalent form of security which assures that any repayments may be obtained
by the Registrant without  delay or litigation, which  bond, insurance or  other
form  of security  must be provided  by the recipient  of the advance,  or (b) a
majority of a quorum of  the Registrant's disinterested, non-party Trustees,  or
an independent legal counsel in a written opinion, shall determine, based upon a
review  of readily available facts that  the recipient of the advance ultimately
will be found entitled to indemnification.

                                      C-3
<PAGE>
    In Section 9 of the Distribution Agreements relating to the securities being
offered hereby,  the Registrant  agrees to  indemnify the  Distributor and  each
person,  if  any,  who  controls  the  Distributor  within  the  meaning  of the
Securities Act  of  1933  (the  "1933 Act"),  against  certain  types  of  civil
liabilities  arising in connection with the Registration Statement or Prospectus
and Statement of Additional Information.

    Insofar as indemnification for liabilities arising under the 1933 Act may be
permitted to Trustees, officers  and controlling persons  of the Registrant  and
the principal underwriter pursuant to the foregoing provisions or otherwise, the
Registrant  has been advised that in the  opinion of the Securities and Exchange
Commission such indemnification  is against  public policy as  expressed in  the
1933  Act  and is,  therefore,  unenforceable. In  the  event that  a  claim for
indemnification  against  such  liabilities  (other  than  the  payment  by  the
Registrant  of expenses incurred  or paid by a  Trustee, officer, or controlling
person of the Registrant  and the principal underwriter  in connection with  the
successful  defense  of any  action,  suit or  proceeding)  is asserted  by such
Trustee,  officer  or  controlling  person  or  the  principal  underwriter   in
connection  with the shares being registered, the Registrant will, unless in the
opinion of its  counsel the matter  has been settled  by controlling  precedent,
submit  to  a  court  of  appropriate  jurisdiction  the  question  whether such
indemnification by it is against public policy as expressed in the 1933 Act  and
will be governed by the final adjudication of such issue.

As of January 1, 1994 Fund Asset Management was reorganized as a limited
partnership, formally known as Fund Asset Management, L.P. ("FAM").  The general
partner of FAM is Princeton Services, Inc. and the limited partners are Fund
Asset Management, Inc. and Merrill Lynch & Co, Inc.  Pursuant to Rule 202(a)(1)-
1 under the Investment Advisors Act of 1940 and Rule 2a-6 under the Investment
Company Act of 1940 such reorganization did not constitute an assignment of this
investment advisory agreement since it did not involve a change of control or
management of the investment adviser.  Pursuant to the requirements of Section
205 of the Investment Advisers Act of 1940, however, Fund Asset Management
hereby supplements this investment advisory agreement by undertaking to advise
you of any change in the membership of the partnership within a reasonable time
after any such change occurs.

                                 CLASS A SHARES

                             DISTRIBUTION AGREEMENT


     AGREEMENT made as of the ____ day of October, 1994, between MERRILL LYNCH
MULTI-STATE MUNICIPAL SERIES TRUST, a Massachusetts business trust (the
"Trust"), and MERRILL LYNCH FUNDS DISTRIBUTOR, INC., a Delaware corporation (the
"Distributor").


                              W I T N E S S E T H :


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

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

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

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

<PAGE>

     WHEREAS, the Trust and the Distributor wish to enter into an agreement with
each other with respect to the continuous offering of the Class A shares of
beneficial interest in the Fund.

     NOW, THEREFORE, the parties agree as follows:

     Section 1.  APPOINTMENT OF THE DISTRIBUTOR.  The Trust hereby appoints the
Distributor as the principal underwriter and distributor of the Trust to sell
Class A shares of beneficial interest in the Fund (sometimes herein referred to
as "Class A shares") to eligible investors (as defined below) and hereby agrees
during the term of this Agreement to sell Class A shares of the Fund to the
Distributor upon the terms and conditions herein set forth.

     Section 2.  EXCLUSIVE NATURE OF DUTIES.  The Distributor shall be the
exclusive representative of the Trust to act as principal underwriter and
distributor, except that:

     (a)  The Trust may, upon written notice to the Distributor, from time to
time designate other principal underwriters and distributors of Class A 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 A shares in the areas so designated shall terminate, but
this Agreement shall remain otherwise in full effect until terminated in
accordance with the other provisions hereof.


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

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

     (d)  Such exclusive right also shall not apply to Class A shares issued
pursuant to any conversion, exchange or reinstatement privilege afforded
redeeming shareholders or to any other Class A shares as shall be agreed between
the Trust and the Distributor from time to time.

     Section 3.  PURCHASE OF CLASS A SHARES FROM THE TRUST.

     (a)  The Distributor shall have the right to buy from the Trust the Class A
shares needed, but not more than the Class A shares needed (except for clerical
errors in transmission) to fill unconditional orders for Class A shares of the
Fund placed with the Distributor by eligible investors or securities dealers.
Investors eligible to purchase Class A shares 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"),


                                        3
<PAGE>

relating to such Class A shares ("eligible investors").  The price which the
Distributor shall pay for the Class A shares so purchased from the Trust 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 A shares are to be resold by the Distributor to eligible
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 A shares, I.E., the price
per share at which the Distributor or selected dealers may sell Class A shares
to eligible investors, shall be the public offering price as set forth in the
prospectus and statement of additional information relating to such Class A
shares, but not to exceed the net asset value at which the Distributor is to
purchase the Class A shares, plus a sales charge not to exceed 4.00% of the
public offering price (4.17% of the net amount invested), subject to reductions
for volume purchases.  Class A shares may be sold to certain Trustees, officers
and employees of the Trust, directors and employees of Merrill Lynch & Co., Inc.
and its subsidiaries, 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


                                        4
<PAGE>

public offering price does not equal an even cent, the public offering price may
be adjusted to the nearest cent.  All payments to the Trust hereunder shall be
made in the manner set forth in Section 3(f).

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

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

     (f)  The Trust, or any agent of the Trust designated in writing by the
Trust, shall be promptly advised of all purchase orders for Class A shares
received by the Distributor.  Any order may be rejected by the Trust; provided,
however, that the Trust will not arbitrarily or without reasonable cause refuse
to accept or confirm orders for the purchase of Class A shares from eligible
investors.  The Trust (or its agent) will confirm orders upon their receipt,
will make appropriate book entries and, upon


                                        5
<PAGE>

receipt by the Trust (or its agent) of payment therefor, will deliver deposit
receipts or certificates for such Class A shares pursuant to the instructions of
the Distributor.  Payment shall be made to the Trust in New York Clearing House
funds.  The Distributor agrees to cause such payment and such instructions to be
delivered promptly to the Trust (or its agent).

     Section 4.  REPURCHASE OR REDEMPTION OF CLASS A SHARES BY THE TRUST.

     (a)  Any of the outstanding Class A shares may be tendered for redemption
at any time, and the Trust agrees to repurchase or redeem the Class A shares so
tendered in accordance with its obligations as set forth in Article VIII of its
Declaration of Trust, as amended from time to time, and in accordance with the
applicable provisions set forth in the prospectus and statement of additional
information.  The price to be paid to redeem or repurchase the Class A 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 Trust
hereunder shall be made in the manner set forth below.  The redemption or
repurchase by the Trust of any of the Class A 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 Class A
shares are tendered for redemption or repur-


                                        6
<PAGE>

chase 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 A shares.

     The Trust 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 Trust 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 A 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 Trust of securities owned by it is not
reasonably practicable or it is not reasonably practicable for the Trust fairly
to determine the value of the net assets of the Fund, or during any other period
when the Securities and Exchange Commission, by order, so permits.

     Section 5.  DUTIES OF THE TRUST.

     (a)  The Trust shall furnish to the Distributor copies of all information,
financial statements and other papers which the


                                        7
<PAGE>

Distributor may reasonably request for use in connection with the distribution
of Class A shares of the Fund, and this shall include, upon request by the
Distributor, one certified copy of all  financial statements prepared for the
Trust by independent public accountants.  The Trust shall make available to the
Distributor such number of copies of the prospectus and statement of additional
information relating to the Fund as the Distributor shall reasonably request.

     (b)  The Trust shall take, from time to time, but subject to any necessary
approval of the Class A shareholders, all necessary action to fix the number of
authorized Class A 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 A shares as the Distributor may reasonably be expected to
sell.

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

     (d)  The Trust 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 A shares of the Fund but shall not be obligated to sell any
specific number of Class A shares.  The services of the Distributor to the Trust

other person is authorized by the Trust to give any information or to make any
representations, other than those contained in the registration statement or
related prospectus and statement of additional information and any sales
literature specifically approved by the Trust.

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


                                        9
<PAGE>

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 A shares and fix therein the portion of the sales charge which may
be allocated to the selected dealers; provided that the Trust shall approve the
forms of agreements with dealers and the dealer compensation set forth therein.
Class A 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

Exhibit A.

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

prospectuses and statements of additional information under the Investment
Company


                                       10
<PAGE>

Act, the Securities Act, and all amendments and supplements thereto, and
preparing and mailing annual and interim reports and proxy materials to Class A
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 A shares to selected dealers or eligible 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 A shares for sale to eligible investors and any
expenses of advertising incurred by the Distributor in connection with such
offering.

     (c)  The Trust shall bear the cost and expenses of qualification of the
Class A shares for sale pursuant to this Agreement and, if necessary or
advisable in connection therewith, of qualifying the Trust as a broker or dealer
in such states of the United States or other jurisdictions as shall be selected
by the


                                       11
<PAGE>

Trust and the Distributor pursuant to Section 5(c) hereof and the cost and
expenses payable to each such state for continuing qualification therein until
the Fund decides to discontinue such qualification pursuant to Section 5(c)
hereof.

     Section 9.  INDEMNIFICATION.

     (a)  The Trust shall indemnify and hold harmless the Distributor and each
person, if any, who controls the Distributor against any loss, liability, claim,
damage or expense (including the reasonable cost of investigating or defending
any alleged loss, liability, claim, damage or expense and reasonable counsel
fees incurred in connection therewith), as incurred, arising by reason of any
person acquiring any Class A shares, which may be based upon the Securities Act,
or on any other statute or at common law, on the ground that the registration
statement or related prospectus and statement of additional information relating
to the Fund, as from time to time amended and supplemented, or an annual or
interim report to 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 Trust in connection therewith by or on behalf of
the Distributor; provided, however, that in no case (i) is the indemnity of the
Trust in favor of the Distributor and any such controlling persons to be deemed
to protect such Distributor or any such controlling persons thereof against any


                                       12
<PAGE>

liability to the Trust or its security holders to which the Distributor or any
such controlling persons would otherwise be subject by reason of willful
misfeasance, bad faith or gross negligence in the performance of their duties or
by reason of the reckless disregard of their obligations and duties under this
Agreement; or (ii) is the Trust to be liable under its indemnity agreement
contained in this paragraph with respect to any claim made against the
Distributor or any such controlling persons, unless the Distributor or such
controlling persons, as the case may be, shall have notified the Trust in
writing within a reasonable time after the summons or other first legal process
giving information of the nature of the claim shall have been served upon the
Distributor or such controlling persons (or after the Distributor or such
controlling persons shall have received notice of such service on any designated
agent), but failure to notify the Trust of any such claim shall not relieve it
from any liability which it may have to the person against whom such action is
brought otherwise than on account of its indemnity agreement contained in this
paragraph.  The Trust will be entitled to participate at its own expense in the
defense or, if it so elects, to assume the defense of any suit brought to
enforce any such liability, but if the Trust elects to assume the defense, such
defense shall be conducted by counsel chosen by it and satisfactory to the
Distributor or such controlling person or persons, defendant or defendants in
the suit.  In the event the Trust elects to assume the defense of any such suit
and retain


                                       13
<PAGE>

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 Trust does not elect to assume the
defense of any such suit, it will reimburse the Distributor or such controlling
person or persons, defendant or defendants in the suit, for the reasonable fees
and expenses of any counsel retained by them.  The Trust shall promptly notify
the Distributor of the commencement of any litigation or proceedings against it
or any of its officers or Trustees in connection with the issuance or sale of
any of the Class A shares.

     (b)  The Distributor shall indemnify and hold harmless the Trust and each
of its Trustees and officers and each person, if any, who controls the Trust
against any loss, liability, claim, damage or expense described in the foregoing
indemnity contained in subsection (a) of this Section, but only with respect to
statements or omissions made in reliance upon, and in conformity with,
information furnished to the Trust in writing by or on behalf of the Distributor
for use in connection with the registration statement or related prospectus and
statement of additional information, as from time to time amended, or the annual
or interim reports to Class A shareholders.  In case any action shall be brought
against the Trust or any person so indemnified, in respect of which indemnity
may be sought against the Distributor, the Distributor shall have the rights and
duties given to the Trust, and the Trust and each person so indemnified


                                       14
<PAGE>

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 the 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 __, 1996 and thereafter, but only for so long as such
continuance is specifically approved at least annually by (i) the Trustees or by
the vote of a majority of the outstanding Class A voting securities of the Fund
and (ii) by the vote of a majority of those Trustees who are not parties to this
Agreement or interested persons of any such party cast in person at a meeting
called for the purpose of voting on such approval.

     This Agreement may be terminated at any time, without the payment of any
penalty, by the Trustees or by vote of a majority of the outstanding Class A
voting securities of the Fund, or by the Distributor, on sixty days' written
notice to the other


                                       15

party.  This Agreement shall automatically terminate in the event of its
assignment.

     The terms "vote of a majority of the outstanding voting securities",

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 by (i) the
Trustees or by the vote of a majority of outstanding Class A voting securities

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 applicable law of the State of New York, or any of

Company Act, the latter shall control.

entered into by the parties hereto with respect to the Class A shares of the
Fund.

     Section 15.  PERSONAL LIABILITY.  The Declaration of Trust establishing

liability, nor shall resort be had to their private property for the
satisfaction of any obligation or claim or otherwise in connection with the
affairs of said Trust, but the "Trust Property" only shall be liable.

     IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of
the day and year first above written.

                           SELECTED DEALERS AGREEMENT


Gentlemen:

     Merrill Lynch Funds Distributor, Inc. (the "Distributor") has an agreement
with MERRILL LYNCH MULTI-STATE MUNICIPAL SERIES TRUST, a Massachusetts business
trust (the "Trust"), pursuant to which it acts as the distributor for the sale
of Class A shares of beneficial interest, par value $0.10 per share (herein
referred to as "Class A shares"), of the Trust relating to Merrill Lynch [State]
Municipal Bond Fund (the "Fund"), and as such has the right to distribute Class
A shares of the Fund for resale.  The Trust is an open-end investment company
registered under the Investment Company Act of 1940, as amended, and the Fund's
Class A shares are registered under the Securities Act of 1933, as amended.  You
have received a copy of the Class A shares Distribution Agreement (the
"Distribution Agreement") between ourself and the Trust and reference is made
herein to certain provisions of such Distribution Agreement.  The terms
"Prospectus" and "Statement of Additional Information" 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 A shares of the Fund for resale to investors identified in the Prospectus
and Statement of Additional Information as eligible to purchase Class A shares
("eligible investors") upon the following terms and conditions:

     1.   In all sales of these Class A shares to eligible investors, you shall
act as dealer for your own account and in no transaction shall you have any
authority to act as agent for the Trust, for us or for any other member of the
Selected Dealers Group, 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 Trust, to participants in such program.

<PAGE>

     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 5 hereof and
instructions which we or the Trust shall forward from time to time to you.  All

charge as set forth in the current Prospectus and Statement of Additional
Information.
</TABLE>

     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 A shares for his or their own account and to
single purchases by a trustee or other fiduciary purchasing Class A 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 A shares of the Fund or Class A 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 certain eligible investors are permitted to purchase Class A 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 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


                                       A-3
<PAGE>

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 eligible investors 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 A shares unless you
have already received purchase orders for such Class A 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 A 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 A 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 A shares of the Fund which is
inconsistent in any respect with the information contained in the Prospectus and
Statement of Additional Information  (as then amended or supplemented) or cause
any advertisement to be published in any newspaper or posted in any public place
without our consent and the consent of the Trust.

     5.   As a selected dealer, you are hereby authorized (i) to place orders
directly with the Trust for Class A 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 A shares
directly to the Trust 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 A shares sold to you under the terms of this Agreement
are repurchased by the Trust or by us for the account of the Trust or are
tendered for redemption within seven


                                       A-4
<PAGE>

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 A shares.

     8.  No person is authorized to make any representations concerning Class A
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 Trust as information supplemental to such
Prospectus and Statement of Additional Information.  In purchasing Class A
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 Trust, and you agree that the Trust 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 A 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


                                       A-5
<PAGE>

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 A 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 A shares
in any jurisdiction.  We will file with the Department of State in New York a
Further State Notice with respect to the Class A shares, if necessary.

     14.  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.

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

                                 CLASS C SHARES

                             DISTRIBUTION AGREEMENT


     AGREEMENT made as of the ______ day of October, 1994, between MERRILL LYNCH
MULTI-STATE MUNICIPAL SERIES TRUST, a Massachusetts business trust (the
"Trust"), and MERRILL LYNCH FUNDS DISTRIBUTOR, INC., a Delaware corporation (the
"Distributor").


                              W I T N E S S E T H :


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

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

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

<PAGE>

     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 Trust and the Distributor wish to enter into an agreement with
each other with respect to the continuous offering of the Fund's Class C shares
in order to promote 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 Trust hereby appoints the
Distributor as the principal underwriter and distributor of the Trust to sell
Class C shares of beneficial interest 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 Trust to act as principal underwriter and
distributor of the Class C shares of the Fund, except that:

     (a)  The Trust may, upon written notice to the Distributor, from time to
time designate other principal underwriters and distributors of Class 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


                                        2
<PAGE>

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 Trust shall not apply to Class C shares of the Fund issued in
connection with the merger or consolidation of any other investment company or
personal holding company with the Trust or the acquisition by purchase or
otherwise of all (or substantially all) the assets or the outstanding Class C
shares of any such company by the Trust.

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

     (d)  Such exclusive right also shall not apply to Class C shares issued
pursuant to any conversion, exchange or reinstatement privilege afforded
redeeming shareholders or to any other Class C shares as shall be agreed between
the Trust and the Distributor from time to time.

     Section 3. PURCHASE OF CLASS C SHARES FROM THE TRUST.

     (a)  The Distributor shall have the right to buy from the Trust the Class C
shares needed, but not more than the Class C shares needed (except for clerical
errors in transmission) to fill unconditional orders for Class C shares of the
Fund placed with the Distributor by eligible investors or securities dealers.


                                        3
<PAGE>

Investors eligible to purchase Class C shares 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 shares so purchased from the Trust shall
be the net asset value, determined as set forth in Section 3(c) hereof.

     (b)  The Class C shares are to be resold by the Distributor to investors at
net asset value, 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 the Fund shall be determined
by the Trust or any agent of the Trust in accordance with the method set forth
in the prospectus and statement of additional information and guidelines
established by the Board of Trustees.

     (d)  The Trust shall have the right to suspend the sale of its Class C
shares at times when redemption is suspended pursuant to the conditions set
forth in Section 4(b) hereof.  The Trust shall also have the right to suspend
the sale of its Class C shares if trading on the New York Stock Exchange shall
have been suspended, if a banking moratorium shall have been declared by


                                        4
<PAGE>

Federal or New York authorities, or if there shall have been some other event,
which, in the judgment of the Trust, makes it impracticable or inadvisable to
sell the Class C shares.

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

     Section 4.  REPURCHASE OR REDEMPTION OF CLASS C SHARES BY THE TRUST.

     (a)  Any of the outstanding Class C shares may be tendered for redemption
at any time, and the Trust agrees to repurchase or redeem the Class C shares so
tendered in accordance with its obligations as set forth in Article VIII of its
Declaration of Trust, as amended from time to time, and in accordance with the
applicable provisions set forth in the prospectus and statement


                                        5
<PAGE>

of additional information of the Fund.  The price to be paid to redeem or
repurchase the Class C shares shall be equal to the net asset value 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 Trust hereunder shall be made in the manner set forth below.

     The Trust shall pay the total amount of the redemption price as defined in
the above paragraph pursuant to the instructions of the Distributor on or before
the seventh business day subsequent to its having received the notice of
redemption in proper form.  The proceeds of any redemption of shares shall be
paid by the Trust as follows:  (i) any applicable 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 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 Trust of securities owned by it is not
reasonably practicable or it is not reasonably practicable for the Trust fairly
to determine the value of the net assets of the


                                        6
<PAGE>

Fund, or during any other period when the Securities and Exchange Commission, by
order, so permits.

     Section 5.  DUTIES OF THE TRUST.

     (a)  The Trust shall furnish to the Distributor copies of all information,
financial statements and other papers which the Distributor may reasonably
request for use in connection with the  distribution of Class C shares of the
Fund, and this shall include, upon request by the Distributor, one certified
copy of all financial statements prepared for the Trust by independent public
accountants.  The Trust shall make available to the Distributor such number of
copies of the prospectus and statement of additional information relating to the
Fund as the Distributor shall reasonably request.

     (b)  The Trust shall take, from time to time, but subject to 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 Trust 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 Trust may approve.
Any such qualification may be withheld, terminated or withdrawn by the Trust at
any time in its discretion.  As provided in Section 8(c) hereof, the


                                        7
<PAGE>

expense of qualification and maintenance of qualification shall be borne by the
Trust.  The Distributor shall furnish such information and other material
relating to its affairs and activities as may be required by the Trust in
connection with such qualification.

     (d)  The Trust 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 Trust
hereunder are not to be deemed exclusive and nothing herein contained shall
prevent the Distributor from entering into like arrangements with other
investment companies so long as the performance of its obligations hereunder is
not impaired thereby.

     (b)  In selling the Class 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 Trust to give any information or to make any
representations, other than those contained in the registration statement or
related prospectus and statement of


                                        8
<PAGE>

additional information and any sales literature specifically approved by the
Trust.

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


                                        9
<PAGE>

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


                                       10
<PAGE>

tributor 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)  The Trust 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 Trust as a broker or dealer
in such states of the United States or other jurisdictions as shall be selected
by the Trust and the Distributor pursuant to Section 5(c) hereof and the cost
and expenses payable to each such state for continuing qualification therein
until the Trust decides to discontinue such qualification pursuant to Section
5(c) hereof.

     Section 9.  INDEMNIFICATION.

     (a)  The Trust shall indemnify and hold harmless the Distributor and each
person, if any, who controls the Distributor against any loss, liability, claim,
damage or expense (including the reasonable cost of investigating or defending
any alleged loss, liability, claim, damage or expense and reasonable counsel
fees incurred in connection therewith), as incurred, arising by reason of any
person acquiring any Class C 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


                                       11
<PAGE>

related prospectus and statement of additional information relating to the Fund,
as from time to time amended and supplemented, or an annual or interim report to
Class 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 Trust in connection therewith by or on behalf of
the Distributor; provided, however, that in no case (i) is the indemnity of the
Trust in favor of the Distributor and any such controlling persons to be deemed
to protect such Distributor or any such controlling persons thereof against any
liability to the Trust or its security holders to which the Distributor or any
such controlling persons would otherwise be subject by reason of willful
misfeasance, bad faith or gross negligence in the performance of their duties or
by reason of the reckless disregard of their obligations and duties under this
Agreement; or (ii) is the Trust to be liable under its indemnity agreement
contained in this paragraph with respect to any claim made against the
Distributor or any such controlling persons, unless the Distributor or such
controlling persons, as the case may be, shall have notified the Trust in
writing within a reasonable time after the summons or other first legal process
giving information of the nature of the claim shall have been served upon the


                                       12
<PAGE>

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


                                       13
<PAGE>

     (b)  The Distributor shall indemnify and hold harmless the Trust and each
of its Trustees and officers and each person, if any, who controls the Trust
against any loss, liability, claim, damage or expense, as incurred, described in
the foregoing indemnity contained in subsection (a) of this Section, but only
with respect to statements or omissions made in reliance upon, and in conformity
with, information furnished to the Trust in writing by or on behalf of the
Distributor for use in connection with the registration statement or related
prospectus and statement of additional information, as from time to time
amended, or the annual or interim reports to shareholders.  In case any action
shall be brought against the Trust or any person so indemnified, in respect of
which indemnity may be sought against the Distributor, the Distributor shall
have the rights and duties given to the Trust, and the Trust and each person so
indemnified shall have the rights and duties given to the Distributor by the
provisions of subsection (a) of this Section 9.

     Section 10.  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 the offering price of shares, the proceeds to be paid to the Fund,
the duties of the Distributor, the payment of


                                       14
<PAGE>

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 __, 1996 and thereafter, but only for so long as such
continuance is specifically approved at least annually by (i) the Trustees or by
the vote of a majority of the outstanding Class C voting securities of the Fund
and (ii) by the vote of a majority of those Trustees who are not parties to this
Agreement or interested persons of any such party cast in person at a meeting
called for the purpose of voting on such approval.

     This Agreement may be terminated at any time, without the payment of any
penalty, by the Trustees or by vote of a majority of the outstanding Class C
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 12.  AMENDMENTS OF THIS AGREEMENT.  This Agreement may be amended
by the parties only if such amendment is specifically approved by (i) the
Trustees or by the vote of a majority


                                       15
<PAGE>

of outstanding Class C voting securities of the Fund and (ii) by the vote of a
majority of those Trustees of the Trust 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 applicable law of the State of New York, or any of
the provisions herein, conflict with the applicable provisions of the Investment

                      CLASS C SHARES OF BENEFICIAL INTEREST

                            SELECTED DEALER AGREEMENT

Gentlemen:

     Merrill Lynch Funds Distributor, Inc. (the "Distributor") has an agreement
with Merrill Lynch Multi-State Municipal Series Trust, a Massachusetts business
trust (the "Trust"), pursuant to which it acts as the distributor for the sale
of Class C shares of beneficial interest, par value $0.10 per share (herein
referred to as the "Class C shares"), of the Trust relating to Merrill Lynch
[State] Municipal Bond Fund (the "Fund") and as such has the right to distribute
Class C shares of the Fund for resale.  The Trust is an open-end investment
company registered under the Investment Company Act of 1940, as amended, and the
Fund's 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 Trust 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 Trust, 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 Trust,
to participants in such program.

     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

<PAGE>

which we or the Trust shall forward from time to time to you.  All orders are
subject to acceptance or rejection by the Distributor or the Trust in the sole
discretion of either.  The minimum initial and subsequent purchase requirements
are as set forth in the current Prospectus and Statement of Additional
Information of the Fund.

     3.  You shall not place orders for any of the Class C shares 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 Trust.

     4.  As a selected dealer, you are hereby authorized (i) to place orders
directly with the Trust 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 Trust 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 withholding:  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 Trust 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


                                       A-2
<PAGE>

proxy solicitation material is our sole responsibility and not the
responsibility of the Trust, and you agree that the Trust shall have no
liability or responsibility to you in these respects unless expressly assumed in
connection therewith.

    7.  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.

    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.


                                       A-3
<PAGE>

    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 purchase of
Class C shares of the Fund will represent your acceptance of this Agreement.

                             DISTRIBUTION AGREEMENT


     AGREEMENT made as of the ____ day of October, 1994, between MERRILL LYNCH
MULTI-STATE MUNICIPAL SERIES TRUST, a Massachusetts business trust (the
"Trust"), and MERRILL LYNCH FUNDS DISTRIBUTOR, INC., a Delaware corporation (the
"Distributor").


                              W I T N E S S E T H :


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

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

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

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

<PAGE>

     WHEREAS, the Trust and the Distributor wish to enter into an agreement with
each other with respect to the continuous offering of the Class D shares of
beneficial interest in the Fund.

     NOW, THEREFORE, the parties agree as follows:

     Section 1.  APPOINTMENT OF THE DISTRIBUTOR.  The Trust hereby appoints the
Distributor as the principal underwriter and distributor of the Trust to sell
Class D shares of beneficial interest 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 Trust to act as principal underwriter and
distributor of the Class D shares of the Fund, except that:

     (a)  The Trust may, upon written notice to the Distributor, from time to
time designate other principal underwriters and distributors of Class 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
this Agreement shall remain otherwise in full effect until terminated in
accordance with the other provisions hereof.


                                        2
<PAGE>

     (b)  The exclusive right granted to the Distributor to purchase Class D
shares from the Trust 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 Trust 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 Trust.

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

     (d)  Such exclusive right also shall not apply to Class D shares issued
pursuant to any conversion, exchange or reinstatement privilege afforded
redeeming shareholders or to any other Class D shares as shall be agreed between
the Trust and the Distributor from time to time.

     Section 3.  PURCHASE OF CLASS D SHARES FROM THE TRUST.

     (a)  The Distributor shall have the right to buy from the Trust 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 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"),


                                        3
<PAGE>

relating to such Class D shares.  The price which the Distributor shall pay for
the Class D shares so purchased from the Trust 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), subject to reductions for volume purchases.
Class D shares may be sold to certain Trustees, officers and employees of the
Trust, directors and employees of Merrill Lynch & Co., Inc. and its
subsidiaries, 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


                                        4
<PAGE>

public offering price does not equal an even cent, the public offering price may
be adjusted to the nearest cent.  All payments to the Trust 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 Trust
or any agent of the Trust in accordance with the method set forth in the
prospectus and statement of additional information of the Fund and guidelines
established by the Trustees.

     (e)  The Trust 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 Trust 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 Trust, makes it impracticable or inadvisable to sell the
Class D shares.

     (f)  The Trust, or any agent of the Trust designated in writing by the
Trust, shall be promptly advised of all purchase orders for Class D shares
received by the Distributor.  Any order may be rejected by the Trust; provided,
however, that the Trust will not arbitrarily or without reasonable cause refuse
to accept or confirm orders for the purchase of Class D shares.  The Trust (or
its agent) will confirm orders upon their receipt, will make appropriate book
entries and, upon receipt by the Trust (or its


                                        5
<PAGE>

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 Trust in New York Clearing House funds.  The Distributor
agrees to cause such payment and such instructions to be delivered promptly to
the Trust (or its agent).

     Section 4.  REPURCHASE OR REDEMPTION OF CLASS D SHARES BY THE TRUST.

     (a)  Any of the outstanding Class D shares may be tendered for redemption
at any time, and the Trust agrees to repurchase or redeem the Class D shares so
tendered in accordance with its obligations as set forth in Article VIII of its
Declaration of Trust, as amended from time to time, and in accordance with the
applicable provisions set forth in the prospectus and statement of additional
information.  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 Trust
hereunder shall be made in the manner set forth below.  The redemption or
repurchase by the Trust of any of the Class D 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 Class D
shares are tendered for redemption or repur-


                                        6
<PAGE>

chase 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 Trust 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 Trust 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 Trust of securities owned by it is not
reasonably practicable or it is not reasonably practicable for the Trust fairly
to determine the value of the net assets of the Fund, or during any other period
when the Securities and Exchange Commission, by order, so permits.

     Section 5.  DUTIES OF THE TRUST.

     (a)  The Trust shall furnish to the Distributor copies of all information,
financial statements and other papers which the


                                        7
<PAGE>

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
Trust by independent public accountants.  The Trust shall make available to the
Distributor such number of copies of the prospectus and statement of additional
information relating to the Fund as the Distributor shall reasonably request.

     (b)  The Trust shall take, from time to time, but subject to 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 Trust 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 Trust may
approve.  Any such qualification may be withheld, terminated or withdrawn by
the Trust at any time in its discretion.  As provided in Section 8(c) hereof,
the expense of qualification and maintenance of qualification shall be borne
by the Trust.  The Distributor shall furnish such information and other
material relating to its affairs and activities as may be required by the Trust
in connection with such qualification.


                                        8
<PAGE>

     (d)  The Trust 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 Trust
hereunder are not to be deemed exclusive and nothing herein contained shall
prevent the Distributor from entering into like arrangements with other
investment companies so long as the performance of its obligations hereunder is
not impaired thereby.

     (b)  In selling the Class 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 Trust to give any information or to make any
representations, other than those contained in the registration statement or
related prospectus and statement of additional information and any sales
literature specifically approved by the Trust.

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


                                        9
<PAGE>

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 Trust 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 Trust shall bear all costs and expenses of the Fund, including
fees and disbursements of its counsel and auditors, in connection with the
preparation and filing of any required registration statements and/or
prospectuses and statements of additional information under the Investment
Company


                                       10
<PAGE>

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 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


                                       11
<PAGE>

be paid from amounts recovered by it from the Fund under such plan.

     (c)  The Trust 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 Trust as a broker or dealer
in such states of the United States or other jurisdictions as shall be selected
by the Trust and the Distributor pursuant to Section 5(c) hereof and the cost
and expenses payable to each such state for continuing qualification therein
until the Trust decides to discontinue such qualification pursuant to Section
5(c) hereof.

     Section 9.  INDEMNIFICATION.

     (a)  The Trust shall indemnify and hold harmless the Distributor and each
person, if any, who controls the Distributor against any loss, liability, claim,
damage or expense (including the reasonable cost of investigating or defending
any alleged loss, liability, claim, damage or expense and reasonable counsel
fees incurred in connection therewith), as incurred, arising by reason of any
person acquiring any Class 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 relating
to the Fund, as from time to time 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


                                       12
<PAGE>

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


                                       13
<PAGE>

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

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


                                       14
<PAGE>

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 Trust or
any person so indemnified, in respect of which indemnity may be sought against
the Distributor, the Distributor shall have the rights and duties given to the
Trust, and the Trust and each person so indemnified shall have the rights and
duties given to the Distributor by the provisions of subsection (a) of this
Section 9.

     Section 10.  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 the 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

and (ii) by the vote of a majority of


                                       15
<PAGE>

those Trustees who are not parties to this Agreement or interested persons of
any such party cast in person at a meeting called for the purpose of voting on
such approval.

     This Agreement may be terminated at any time, without the payment of any
penalty, by the Trustees or by vote of a majority of the outstanding Class D
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 12.  AMENDMENTS OF THIS AGREEMENT.  This Agreement may be amended

Trustees or by the vote of a majority of outstanding Class C voting securities
of the Fund and (ii) by the vote of a majority of those Trustees of the Trust
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

Act.  To the extent that the applicable law of the State of New York, or any


                                       16
<PAGE>

of the provisions herein, conflict with the applicable provisions of the
Investment Company Act, the latter shall control.

Merrill Lynch Multi-State Municipal Series Trust, dated August 2, 1985, a copy
of which, together with all amendments thereto (the "Declaration"), is on file
in the office of the Secretary of the Commonwealth of Massachusetts, provides
that the name "Merrill Lynch Multi-State Municipal Series Trust" refers to the
Trustees under the Declaration collectively as trustees, but not as individuals
or personally; and no Trustee, shareholder, officer, employee or agent of said
Trust shall be held to any personal liability, nor shall resort be had to their
private property for the satisfaction of any obligation or claim or otherwise in
connection with the affairs of said Trust, but the "Trust Property" only shall
be liable.

     IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of
the day and year first above written.

Gentlemen:

     Merrill Lynch Funds Distributor, Inc. (the "Distributor") has an agreement
with MERRILL LYNCH MULTI-STATE MUNICIPAL SERIES TRUST, a Massachusetts business
trust (the "Trust"), pursuant to which it acts as the distributor for the sale
of Class D shares of beneficial interest, par value $0.10 per share (herein
referred to as "Class D shares"), of the Trust relating to Merrill Lynch [State]
Municipal Bond Fund (the "Fund"), and as such has the right to distribute Class
D shares of the Fund for resale.  The Trust is an open-end investment company
registered under the Investment Company Act of 1940, as amended, and the Fund's
Class D shares being offered to the public are registered under the Securities
Act of 1933, as amended.  You have received a copy of the Class D Shares
Distribution Agreement (the "Distribution Agreement") between ourself and the
Trust and reference is made herein to certain provisions of such Distribution
Agreement.  The terms "Prospectus" and "Statement of Additional Information"
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 D shares of the Fund upon the following terms and
conditions:

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

     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


                                       A-1

</TABLE>

     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


                                       A-2
<PAGE>

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 dollar amount 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 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


                                       A-3
<PAGE>

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 Trust.

     5.   As a selected dealer, you are hereby authorized (i) to place orders
directly with the Trust 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 Trust 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 Trust or by us for the account of the Trust 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 the Trust as information supplemental to such
Prospectus and


                                       A-4
<PAGE>

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 Trust, and you agree that the Trust 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


                                       A-5
<PAGE>

shares in any jurisdiction.  We will file with the Department of State in New
York a Further State Notice with respect to the Class D shares, if necessary.

     14.  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.

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

     DISTRIBUTION PLAN made as of the      day of October, 1994, by and between
Merrill Lynch Multi-State Municipal Series Trust, a Massachusetts business trust

                              W I T N E S S E T H:

     WHEREAS, the Trustees of the Trust have determined that there is a

<PAGE>

under the Investment Company Act on the following terms and conditions:

     1.  The Trust shall pay MLFD an account maintenance fee under the Plan at

the Fund relating to Class C shares 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
C shareholders of the Fund.  Expenditures under the Plan may consist of payments
to financial consultants for maintaining accounts in connection with Class C
shares 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.

     2.  The Trust shall pay MLFD a distribution fee under the Plan at the end
of each month at the annual rate of 0.35% of average daily net assets of the

distribution fee described in this Paragraph 2 shall be subject to any
limitations set forth in any applicable regulation of the National Association
of Securities Dealers, Inc.

     3.  The Trust 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 or

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 4 hereof.

     4.  MLFD shall provide the Trust for review by the Board of Trustees, and
the Trustees 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 the distribution fee during such period.

     5.  This Plan shall not take effect until it has been approved by a vote of
at least a majority, as defined in the Investment Company Act, of the
outstanding Class C voting securities of the Fund.

     6.  This Plan shall not take effect until it has been approved, together
