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

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

    Pursuant  to the  Merrill Lynch Select  Pricing-SM- System,  the Fund offers
four classes of  shares, each  with a  different combination  of sales  charges,
ongoing  fees and  other features. The  Merrill Lynch  Select Pricing-SM- System
permits an investor to choose the method of purchasing shares that the  investor
believes is most beneficial given the amount of the purchase, the length of time
the  investor expects to  hold the shares and  other relevant circumstances. See
"Merrill Lynch Select Pricing-SM- System" on page 4.

    Shares may be purchased directly from Merrill Lynch Funds Distributor,  Inc.
(the  "Distributor"),  P.O. Box  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".

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

                    MERRILL LYNCH SELECT PRICING-SM- SYSTEM

    The Fund  offers four  classes  of shares  under  the Merrill  Lynch  Select
Pricing-SM-  System. The shares of each class  may be purchased at a price equal
to the next determined net  asset value per share  subject to the sales  charges
and  ongoing fee  arrangements described  below. Shares of  Class A  are sold to
investors choosing the initial sales charge alternatives, and shares of Class  B
and   Class  C  are  sold  to  investors  choosing  the  deferred  sales  charge
alternatives. The Merrill Lynch Select Pricing-SM-  System is used by more  than
50  mutual funds advised by Merrill Lynch  Asset Management, L.P. ("MLAM") or an
affiliate of MLAM, Fund Asset Management,  L.P. ("FAM" or the "Manager").  Funds
advised by MLAM or FAM are referred to herein as "MLAM-advised mutual funds".

    Each  Class A, Class B, Class  C or Class D share  of the Fund represents an
identical interest in  the investment  portfolio of the  Fund and  has the  same
rights, except that Class B, Class C and Class D shares bear the expenses of the
ongoing  account  maintenance fees  and  Class B  and  Class C  shares  bear the
expenses of  the  ongoing  distribution  fees  and  the  additional  incremental
transfer agency costs resulting from the deferred sales charge arrangements. The
deferred  sales charges and account maintenance fees that are imposed on Class B
and Class C shares, as well as the account maintenance fees that are imposed  on
the  Class D  shares, 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-SM- System that the investor believes is
most beneficial under his particular circumstances. More detailed information as
to  each  class   of  shares   is  set   forth  under   "Purchase  of   Shares".

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

<TABLE>
<S>       <C>
CLASS A:  Class A shares  incur an  initial sales  charge when  they are purchased  and bear  no ongoing  distribution or  account
          maintenance  fees. Class A shares are offered to a limited  group of investors and also will be issued upon reinvestment
          of dividends on outstanding Class  A shares. Investors that  currently own Class A shares  in a shareholder account  are
          entitled  to purchase additional Class A shares in that account.  In addition, Class A shares will be offered to Merrill
          Lynch & Co., Inc. ("ML & Co.") and its subsidiaries (the term "subsidiaries", when used herein with respect to ML & Co.,
          includes MLAM, the Manager and certain  other entities directly or indirectly wholly-owned  and controlled by ML &  Co.)
          and  their directors and employees and to members of the  Boards of MLAM-advised mutual funds. The maximum initial sales
          charge is 4.00%, which is reduced for purchases of $25,000 and over. Purchases of $1,000,000 or more may not be  subject
          to  an initial sales charge, but  if the initial sales charge  is waived, such purchases may  be subject to a contingent
          deferred sales charge ("CDSC") if the shares are redeemed within one year after purchase. Sales charges are also reduced
          under a right of

          accumulation which takes  into account the  investor's holdings  of all classes  of all MLAM-advised  mutual funds.  See
          "Purchase of Shares -- Initial Sales Charge Alternatives -- Class A and Class D Shares."

CLASS B:  Class  B shares  do not  incur a  sales charge  when they  are purchased,  but they  are subject  to an  ongoing account
          maintenance fee of 0.25%, an  ongoing distribution fee of 0.25%  of average net assets 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 is modified as described under "Purchase of Shares -- Deferred  Sales
          Charge Alternatives -- Class B and Class C Shares -- Conversion of Class B Shares to Class D Shares."

CLASS C:  Class  C shares  do not  incur a  sales charge  when they  are purchased,  but they  are subject  to an  ongoing account
          maintenance fee of 0.25% and an ongoing distribution fee of 0.35% of average net assets. Class C shares are also subject
          to a CDSC if they are redeemed within one year of purchase. Although Class C shares are subject to a 1.0% CDSC for  only
          one  year (as compared to four years for Class B shares), Class C shares have no conversion feature and, accordingly, an
          investor that purchases Class C shares will be subject to  distribution fees that will be imposed on Class C shares  for
          an indefinite period subject to annual approval by the Fund's Board of Trustees and regulatory limitations.

CLASS D:  Class  D shares incur an initial sales charge when they  are purchased and are subject to an ongoing account maintenance
          fee of 0.10% of 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"
          above. See "Purchase of Shares -- Initial Sales Charge Alternatives -- Class A and Class D Shares."

    The  following is a discussion of the factors that investors should consider
in determining the method  of purchasing shares under  the Merrill Lynch  Select
Pricing-SM-  System  that the  investor believes  is  most beneficial  under his
particular circumstances.

    INITIAL SALES CHARGE ALTERNATIVES.   Investors who  prefer an initial  sales
charge  alternative may  elect to  purchase Class  D shares  or, if  an eligible
investor,  Class  A  shares.  Investors   choosing  the  initial  sales   charge
alternative  who are eligible to purchase Class A shares should purchase Class A
shares rather than Class D 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.  Although  some  investors  that  previously
purchased Class A shares may no longer be eligible to purchase Class A shares of
other  MLAM-advised  mutual funds,  those previously  purchased Class  A shares,
together with Class B shares holdings, will count toward a right of accumulation
which may qualify the investor for reduced initial sales charges on new  initial
sales charge purchases. In addition, the ongoing Class B account maintenance and
distribution  fees will cause Class B shares  to have higher expense ratios, pay
lower dividends  and have  lower total  returns than  the initial  sales  charge
shares.

    DEFERRED  SALES CHARGE ALTERNATIVES.   Because no  initial sales charges are
deducted at the time of purchase, Class B shares provide the benefit of  putting
all  of the investor's dollars to work from the time the investment is made. The
deferred sales charge  alternatives may be  particularly appealing to  investors
who  do not quality for a reduction in initial sales charges. Class B shares are
subject to ongoing account maintenance fees and distributions fees; however, the
ongoing account maintenance and distribution  fees potentially may be offset  to
the  extent any return is realized on the additional funds initially invested in
Class B or Class C shares.

    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. In addition, while both Class  B and Class C distribution fees are
subject to the limitations on asset-based sales charges imposed by the NASD, the
Class B  distribution fees  are  further limited  under  a voluntary  waiver  of
asset-based sales charges. See "Purchase of Shares -- Limitations on the Payment
of Deferred Sales Charges."

                       INVESTMENT OBJECTIVE AND POLICIES

    The investment objective of the Fund is to provide shareholders with as high
a level of income exempt from Federal and Pennsylvania personal income taxes  as
is  consistent with prudent investment management. The Fund seeks to achieve its
objective by investing primarily in a portfolio of long-term obligations  issued
by or on behalf of the Commonwealth of Pennsylvania, its political subdivisions,
agencies and instrumentalities and obligations of other qualifying issuers, such
as  issuers located  in Puerto  Rico, the  Virgin Islands,  and Guam,  which pay
interest exempt, in the opinion of bond counsel to the issuer, from Federal  and
Pennsylvania personal income taxes. Obligations exempt from Federal income taxes
are  referred to  herein as "Municipal  Bonds" and obligations  exempt from both
Federal and Pennsylvania income taxes are referred to as "Pennsylvania Municipal
Bonds." Unless  otherwise  indicated, references  to  Municipal Bonds  shall  be
deemed  to include Pennsylvania  Municipal Bonds. The Fund  at all times, except
during temporary defensive  periods, will  maintain at  least 65%  of its  total
assets invested in Pennsylvania Municipal Bonds. The investment objective of the
Fund  as set  forth in  the first  sentence of  this paragraph  is a fundamental
policy of the Fund which may not be changed without a vote of a majority of  the
outstanding shares of the Fund.

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

    The  Fund may invest up  to 20% of its total  assets in Municipal Bonds that
are rated below Baa by Moody's or below BBB by Standard & Poor's or Fitch.  Such
securities,   sometimes  referred  to  as  "high-yield"  or  "junk"  bonds,  are
predominantly speculative with respect to the capacity to pay interest and repay
principal in accordance with the terms  of the security and generally involve  a
greater  volatility of  price than securities  in higher  rating categories. The
market prices of high-yielding, lower-rated  securities may fluctuate more  than
higher-rated  securities  and may  decline significantly  in periods  of general
economic difficulty,  which may  follow  periods of  rising interest  rates.  In
purchasing such securities, the Fund will rely on the

                                       9
<PAGE>
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  include variable rate  demand obligations  ("VRDOs")
and  VRDOs in  the form  of participation  interests ("Participating  VRDOs") in
variable rate tax-exempt obligations held by a financial institution. The  VRDOs
in  which  the  Fund will  invest  are  tax-exempt obligations  which  contain a
floating or variable interest rate adjustment formula and an unconditional right
of demand on the  part of the  holder thereof to receive  payment of the  unpaid
principal  balance plus accrued interest on a  short notice period not to exceed
seven days.  Participating VRDOs  provide the  Fund with  a specified  undivided
interest  (up to  100%) of  the underlying  obligation and  the right  to demand
payment  of  the  unpaid  principal   balance  plus  accrued  interest  on   the
Participating  VRDOs from  the financial  institution on  a specified  number of
days' notice, not to exceed seven days. There is, however, some possibility that
because of default or insolvency, the  demand feature of VRDOs or  Participating
VRDOs may not be honored. The Fund has been advised by its counsel that the Fund
should  be  entitled to  treat  the income  received  on Participating  VRDOs as
interest from tax-exempt obligations.

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

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

                                       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  Pennsylvania 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 Federal alternative minimum tax. The percentage of the Fund's  net
assets  invested  in "private  activity bonds"  will vary  during the  year. See
"Distributions and Taxes". In  addition, the Fund reserves  the right to  invest
temporarily  a  greater  portion  of its  assets  in  Temporary  Investments for
defensive purposes,  when, in  the judgment  of the  Manager, market  conditions
warrant.  The investment objective  of the Fund  is a fundamental  policy of the
Fund which may not be  changed without a vote of  a majority of the  outstanding
shares  of the Fund. The Fund's hedging  strategies, which are described in more
detail under "Financial Futures Transactions  and Options," are not  fundamental
policies  and may be modified by the  Trustees of the Trust without the approval
of the Fund's shareholders.

POTENTIAL BENEFITS

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

SPECIAL AND RISK CONSIDERATIONS RELATING TO PENNSYLVANIA MUNICIPAL BONDS

    The  Fund  ordinarily  will invest  at  least  65% of  its  total  assets in
Pennsylvania Municipal Bonds, and  therefore it is  more susceptible to  factors
adversely  affecting issuers of Pennsylvania Municipal Bonds than is a municipal
bond mutual fund that is not  concentrated in issuers of Pennsylvania  Municipal
Bonds to this degree.

    Many  different social,  environmental and  economic factors  may affect the
financial condition of Pennsylvania and its political subdivisions. From time to
time Pennsylvania and certain of its political

                                       11
<PAGE>
subdivisions  have  encountered  financial  difficulties  which  have  adversely
affected their respective credit standings. For example, the financial condition
of  the City of Philadelphia had impaired  its ability to borrow and resulted in
its obligations generally being downgraded by the major rating services to below
investment grade. Other factors which may negatively affect economic  conditions
in  Pennsylvania include  adverse changes  in employment  rates, Federal revenue
sharing or laws with respect to tax-exempt financing. Currently,  Pennsylvania's
general  obligation bonds are rated AA- by Standard & Poor's and Fitch and A1 by
Moody's. See "Description  of Municipal  Bonds" in the  Statement of  Additional
Information and see also Appendix I to the Statement of Additional Information.

DESCRIPTION OF MUNICIPAL BONDS

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

    The  two  principal   classifications  of  Municipal   Bonds  are   "general
obligation"  and "revenue" bonds which include  IDBs and, for bonds issued after
August 15, 1986, private activity bonds. General obligation bonds are secured by
the issuer's pledge of  its faith, credit  and taxing power  for the payment  of
principal  and  interest. The  taxing power  of any  governmental entity  may be
limited, however, by provisions of state constitutions or laws, and an  entity's
creditworthiness will depend on many factors, including potential erosion of the
tax  base due to population declines, natural disasters, declines in the state's
industrial base or inability to attract  new industries, economic limits on  the
ability  to tax  without eroding  the tax  base, state  legislative proposals or
voter initiatives to  limit ad valorem  real property taxes,  and the extent  to
which  the entity relies on  Federal or state aid,  access to capital markets or
other factors beyond the state or entity's control. Accordingly, the capacity of
the issuer of a general obligation bond as to the timely payment of interest and
the repayment of principal when due  is affected by the issuer's maintenance  of
its tax base.

    Revenue  bonds are payable only from  the revenues derived from a particular
facility or  class of  facilities or,  in some  cases, from  the proceeds  of  a
special excise tax or other specific revenue source such as from the user of the
facility  being financed;  accordingly, the timely  payment of  interest and the
repayment of principal in  accordance with the terms  of the revenue or  special
obligation bond is a function of the economic viability of such facility or such
revenue source. The Fund does not presently intend to invest more than 5% of its
total  assets (taken at market value at the  time of each investment) in IDBs or
private activity bonds where  the entity supplying the  revenues from which  the
issuer is paid, including predecessors, has a record of less than three years of
continuous  business operations.  Investments involving entities  with less than
three years

                                       12
<PAGE>
of continuous business  operations may pose  somewhat greater risks  due to  the
lack of a substantial operating history for such entities. The Manager believes,
however,  that the potential benefits of such investments outweigh the potential
risks, particularly given the Fund's limitations on such investments.

    The Fund  may purchase  IDBs  or private  activity  bonds. IDBs  or  private
activity  bonds are  tax-exempt securities  issued by  states, municipalities or
public authorities and are  issued to provide funds,  usually through a loan  or
lease  arrangement,  to  a  private corporation  for  the  purpose  of financing
construction or improvement of  a facility to be  used by the corporation.  Such
bonds  are secured primarily  by revenues derived from  loan repayments or lease
payments due from the corporation which may or may not be guaranteed by a parent
company or otherwise secured. In view of this, an investor should be aware  that
repayment  of such bonds depends on the revenues of a private corporation and be
aware of the risks that  such an investment may  entail. Continued ability of  a
corporation  to generate  sufficient revenues for  the payment  of principal and
interest on such bonds will  be affected by many  factors including the size  of
the  corporation,  capital  structure,  demand  for  its  products  or services,
competition,  general  economic  conditions,   government  regulation  and   the
corporation's  dependence  on  revenues  for  the  operation  of  the particular
facility being financed. The Fund may invest  more than 25% of its total  assets
in  IDBs  or  private  activity  bonds.  The  Fund  may  also  invest  in "moral
obligation"  bonds,  which  are  normally  issued  by  special  purpose   public
authorities.  If  an issuer  of moral  obligation  bonds is  unable to  meet its
obligations, the repayment of  such bonds becomes a  moral commitment but not  a
legal obligation of the state or municipality in question.

    The  Fund  may  invest  in  Municipal  Bonds  (and  Non-Municipal Tax-Exempt
Securities) the return  on which  is based  on a  particular index  of value  or
interest  rates. For example,  the Fund may  invest in Municipal  Bonds that pay
interest based on  an index of  Municipal Bond  interest rates or  based on  the
value  of  gold  or some  other  commodity.  The principal  amount  payable upon
maturity of certain Municipal Bonds also may be based on the value of an  index.
To  the extent the  Fund invests in  these types of  Municipal Bonds, the Fund's
return on such Municipal Bonds will be subject to risk with respect to the value
of the  particular  index. 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.
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 10% 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

                                       13
<PAGE>
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  10% 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  to  be liquid  if  they are
publicly offered and have received an  investment grade rating of Baa or  better
by  Moody's,  or BBB  or better  by Standard  & Poor's  or Fitch.  Unrated lease
obligations, or those rated below investment grade, will be considered liquid if
the obligations come to the market  through an underwritten public offering  and
at  least two dealers are willing to  give competitive bids. In reference to the
latter, the Manager must, among  other things, also review the  creditworthiness
of  the municipality  obligated to make  payment under the  lease obligation and
make certain specified determinations based on such factors as the existence  of
a  rating or credit  enhancement such as  insurance, the frequency  of trades or
quotes for the obligation and the willingness of dealers to make a market in the
obligation.

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

CALL RIGHTS

    The  Fund may  purchase a  Municipal Bond  issuer's right  to call  all or a
portion of  such Municipal  Bond  for mandatory  tender  for purchase  (a  "Call
Right"). A holder of a Call Right may exercise such right to require a mandatory
tender  for  the  purchase  of  related  Municipal  Bonds,  subject  to  certain
conditions. A Call  Right that is  not exercised  prior to the  maturity of  the
related Municipal Bond will expire without value. The economic effect 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 10% of the Fund's net assets.

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

                                       14
<PAGE>
price. A separate  account of the  Fund will be  established with its  custodian
consisting  of  cash, cash  equivalents or  high  grade, liquid  Municipal Bonds
having a market value at all times at  least equal to the amount of the  forward
commitment.

FINANCIAL FUTURES TRANSACTIONS AND OPTIONS

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

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

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

                                       15
<PAGE>
bond indexes which  may become  available if  the Manager  of the  Fund and  the
Trustees  of  the Trust  should determine  that there  is normally  a sufficient
correlation between the prices of such futures contracts and the Municipal Bonds
in which the Fund invests to make such hedging appropriate.

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

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

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

    Although certain risks are involved in options and futures transactions, the
Manager believes that, because the Fund will engage in futures transactions only
for  hedging purposes,  the futures  portfolio strategies  of the  Fund will not
subject the  Fund to  certain risks  frequently associated  with speculation  in
futures transactions. The Fund must meet certain Federal income tax requirements
under  the Internal Revenue Code  of 1986, as amended  (the "Code"), in order to
qualify for the special tax  treatment afforded regulated 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.

                                       16

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

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

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

REPURCHASE AGREEMENTS

    As Temporary  Investments, the  Fund may  invest in  securities pursuant  to
repurchase  agreements. Repurchase  agreements may be  entered into  only with a
member bank of the Federal Reserve System or a primary dealer in U.S. Government
Securities or an affiliate  thereof. Under such  agreements, the seller  agrees,
upon  entering into the contract, to repurchase  the security from the Fund at a
mutually agreed upon time  and price, thereby determining  the yield during  the
term  of the agreement.  This results in  a fixed rate  of return insulated from
market fluctuations during such  period. The Fund may  not invest in  repurchase
agreements  maturing in more than seven  days if such investments, together with
the Fund's other illiquid investments, exceed  10% of the Fund's net assets.  In
the  event of default by  the seller under a  repurchase agreement, the Fund may
suffer time delays  and incur costs  or possible losses  in connection with  the
disposition of the underlying securities.

INVESTMENT RESTRICTIONS

    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

                                       17
<PAGE>
negotiated loans that constitute illiquid investments and 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 10%  of
its  net assets (taken at market value at  the time of each investment) would be
invested in such securities; (vi) invest more than 5% 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,
including predecessors,  has  a record  of  less than  three  years'  continuous
business operation; and (vii) 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 or Municipal Bonds).

    Under  prior Pennsylvania  law, in  order for  the Fund  to qualify  to pass
through to investors income  exempt from Pennsylvania  personal income tax,  the
Fund  was required  to adhere  to certain  investment restrictions.  In order to
comply with this and other  Pennsylvania law requirements previously in  effect,
the  Fund adopted,  as a  fundamental policy,  a requirement  that it  invest in
securities for income  earnings rather  than trading  for profit,  and that,  in
accordance with such policy, it not vary its portfolio investments except to (i)
eliminate unsafe investments or investments not consistent with the preservation
of  the capital  or the tax  status of the  investments of the  Fund; (ii) honor
redemption orders, meet  anticipated redemption requirements,  and negate  gains
from  discount purchases;  (iii) reinvest the  earnings from  securities in like
securities; or  (iv) defray  normal  administrative expenses.  Pennsylvania  has
recently  enacted legislation which  eliminated the necessity  for the foregoing
investment policies. Since such policies  are fundamental policies of the  Fund,
which  can only  be changed by  the affirmative  vote of a  majority (as defined
under the Investment Company Act) of the outstanding shares, the Fund  continues
to be governed by such investment policies.

    The  Fund is  classified as non-diversified  within the meaning  of the 1940
Act, which means that the Fund is not limited by the 1940 Act in the  proportion
of its assets that it may invest in obligations of a single issuer. However, the
Fund's  investments will be limited  so as to qualify  for the special treatment
afforded regulated investment companies under the Code. See "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.

    The  Board of Trustees  of the Trust, at  a meeting held  on August 4, 1994,
approved certain  changes  to  the fundamental  and  non-fundamental  investment
restrictions  of the  Fund. These changes  were proposed in  connection with the
creation of  a  set  of  standard  fundamental  and  non-fundamental  investment
restrictions  that would be adopted, subject  to shareholder approval, by all of
the non-money market mutual funds advised  by MLAM or FAM. The proposed  uniform
investment  restrictions are designed to provide  each of these funds, including
the Fund, with as much investment flexibility as possible under the 1940 Act and
applicable state securities regulations,  help promote operational  efficiencies
and  facilitate monitoring of compliance. The investment objectives and policies
of the  Fund will  be unaffected  by  the adoption  of the  proposed  investment
restrictions.
    

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

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

<PAGE>
MANAGEMENT AND ADVISORY ARRANGEMENTS

    FAM,  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  individual  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 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 $852,481 (based upon average net assets  of
approximately $155.4 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  Trustee's fees  and expenses,  registration
fees,  custodian and  transfer agency  fees, accounting  and pricing  costs, and
certain of the costs of printing proxies, shareholder reports, prospectuses  and
statements  of additional information.  Accounting services are  provided to the
Fund by  the Manager  and  the Fund  reimburses the  Manager  for its  costs  in
connection  with  such services.  The  Manager may  voluntarily  waive all  or a
portion of its management fee and may voluntarily assume all or a portion of the
Fund's expenses.  For the  year ended  July 31,  1994, the  Fund reimbursed  the
Manager $58,164 for accounting services.

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  and Class C  shareholder account and  the Transfer Agent is
entitled to reimbursement from the Fund for out-

                                       20
<PAGE>
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  $70,506 pursuant to  the Transfer Agency  Agreement for  providing
transfer agency services.

                               PURCHASE OF SHARES

    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-SM-  System,  as  described  below. The  applicable  offering  price for
purchase orders is based upon  the net asset value  of the Fund next  determined
after  receipt of the purchase orders by  the Distributor. As to purchase orders
received by securities dealers prior to 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 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-SM-  System,  which  permits  each  investor  to  choose  the  method of
purchasing shares that the investor believes is most beneficial given the amount
of the purchase, the length of time the investor expects to hold the shares  and
other  relevant  circumstances.  Shares of  Class  A  and Class  D  are  sold to
investors choosing the initial sales charge  alternatives and shares of Class  B
and   Class  C  are  sold  to  investors  choosing  the  deferred  sales  charge
alternatives.  Investors  should  determine   whether  under  their   particular
circumstances  it is more  advantageous to incur  an initial sales  charge or to
have the entire initial purchase price invested in the Fund with the  investment
thereafter  being  subject to  a contingent  deferred  sales charge  and ongoing
distribution fees. A discussion of the factors that investors should consider in
determining the  method of  purchasing  shares under  the Merrill  Lynch  Select
Pricing-SM-  System is set forth under "Merrill Lynch Select Pricing-SM- System"
on page 4.

    Each Class A,  Class B, Class  C and Class  D share of  the Fund  represents
identical  interests in the  investment portfolio of  the Fund and  has the same
rights, except that Class B, Class C and Class D shares bear the expenses of the
ongoing account  maintenance fees,  and Class  B  and Class  C shares  bear  the
expenses  of  the  ongoing  distribution  fees  and  the  additional incremental
transfer agency costs resulting from

                                       21
<PAGE>
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.

    The  following table sets  forth a summary  of the distribution arrangements
for each class of shares under the Merrill Lynch Select Pricing-SM- System.

(1)  Initial sales charges are imposed at  the time of purchase as a  percentage
     of the offering price. CDSCs may be imposed if the redemption occurs within
     the  applicable CDSC time period. The charge  will be assessed on an amount
     equal to the lesser of the proceeds of redemption or the cost of the shares
     being redeemed.
(2)  Offered only to eligible investors. See "Initial Sales Charge  Alternatives
     -- Class A and Class D Shares -- Eligible Class A Investors."
(3)  Reduced  for  purchases of  $25,000  or more.  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.

     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

     October 21, 1994 will be subject to a CDSC of 1% if the shares are redeemed
     within one year after purchase. Class A purchases made prior to October 21,
     1994 may be subject to a CDSC if the shares are redeemed within one year of
     purchase at  the  following rates:  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.

    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  550,023
Class A shares for aggregate net proceeds of $6,297,702. The gross sales charges
for  the sale of Class A shares of the Fund for that year were $93,697, of which
$8,083  and  $85,614  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

                                       23
<PAGE>
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 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 a sales charge, to an
investor who  has  a  business  relationship  with  a  Merrill  Lynch  financial
consultant  if  certain  conditions set  forth  in the  Statement  of Additional
Information are  met. Class  D  shares may  be offered  at  net asset  value  in
connection with the acquisition of assets of other investment companies.

    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.

                                       24
<PAGE>
    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 CDSCs and the distribution fee are paid to the Distributor
and  are used in whole or  in part by the Distributor  to defray the expenses of
dealers (including  Merrill  Lynch) related  to  providing  distribution-related
services  to the Fund  in connection with  the sale of  the Class B  and Class C
shares, such as the payment of compensation to financial consultants for selling
Class B and Class C shares from  the dealer's own funds. The combination of  the
CDSC  and the ongoing  distribution fee facilitates  the ability of  the Fund to
sell the Class B and Class C shares without a sales charge being deducted at the
time of purchase. Approximately  ten years after issuance,  Class B shares  will
convert  automatically into Class D  shares of the Fund,  which are subject to a
lower account maintenance fee and no distribution fee; Class B shares of certain
other MLAM-advised mutual funds  into which exchanges may  be made convert  into
Class  D shares automatically after approximately eight years. If Class B shares
of the Fund  are exchanged  for Class B  shares of  another MLAM-advised  mutual
fund,  the conversion period  applicable to the  Class B shares  acquired in the
exchange will apply,  and the holding  period for the  shares exchanged will  be
tacked onto the holding period for the shares acquired.

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

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

    The following table sets forth the rates of the Class B CDSC:

    For  the fiscal year ended July 31,  1994, the Distributor received CDSCs of
$204,747 with respect to redemptions of Class  B shares, all of which were  paid
to Merrill Lynch.

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

    To provide an example,  assume an investor purchased  100 Class B shares  at
$10  per share (at a cost  of $1,000) and in the  third year after purchase, the
net asset  value per  share  is $12  and, during  such  time, the  investor  has
acquired  10 additional shares  upon dividend reinvestment. If  at such time the
investor makes his first redemption of  50 shares (proceeds of $600), 10  shares
will  not be subject to charge because of dividend reinvestment. With respect to
the remaining 40 shares, the  CDSC is applied only to  the original cost of  $10
per share and not 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 Code)  of a  shareholder. Additional information
concerning the waiver  of the  Class B  CDSC is set  forth in  the Statement  of
Additional Information.

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

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

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

                                       26
<PAGE>
    In  addition, shares purchased through reinvestment  of dividends on Class B
shares also will convert  automatically to Class D  shares. The Conversion  Date
for  dividend reinvestment  shares will  be calculated  taking into  account the
length of  time the  shares underlying  such dividend  reinvestment shares  were
outstanding. If at a Conversion Date the conversion of Class B shares to Class D
shares  of the Fund  in a single account  will result in less  than $50 worth of
Class B shares being left in the account, all of the Class B shares of the  Fund
held  in the account on the Conversion Date  will be converted to Class D shares
of the Fund.

    Share certificates for Class B  shares of the Fund  to be converted must  be
delivered  to the Transfer Agent at least  one week prior to the Conversion Date
applicable to those shares. In the  event such certificates are not received  by
the  Transfer Agent at least one week  prior to the Conversion Date, the related
Class B shares will convert to Class  D shares on the next scheduled  Conversion
Date after such certificates are delivered.

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

DISTRIBUTION PLANS

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

    The  Distribution Plans for Class B, Class C and Class D shares each provide
that the Fund pays  the Distributor an account  maintenance fee relating to  the
shares  of the  relevant class,  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

                                       27
<PAGE>
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 $314,893 and distribution fees of $314,894 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  Plan are  based  on a  percentage  of
average  daily net assets attributable to the shares regardless of the amount of
expenses incurred  and,  accordingly,  distribution-related  revenues  from  the
Distribution  Plans  may be  more  or less  than  distribution-related expenses.
Information with respect  to the distribution-related  revenues and expenses  is
presented  to  the Trustees  for their  consideration  in connection  with their
deliberations as to  the continuance  of the Class  B and  Class C  Distribution
Plans.  This information is presented annually as of December 31 of each year on
a "fully  allocated  accrual" basis  and  quarterly  on a  "direct  expense  and
revenue/cash"  basis. On the fully allocated  accrual basis, revenues consist of
the account maintenance  fees, distribution  fees, the CDSCs  and certain  other
related  revenues, and  expenses consist  of financial  consultant compensation,
branch office and regional operation  center selling and transaction  processing
expenses,   advertising,  sales  promotion  and  marketing  expenses,  corporate
overhead and interest  expense. On  the direct expense  and revenue/cash  basis,
revenues  consist of the  account maintenance fees,  distribution fees and CDSCs
and the expenses consist  of financial consultant  compensation. As of  December
31,  1993 the fully  allocated accrual expenses incurred  by the Distributor and
Merrill Lynch  exceeded fully  allocated  accrual revenues  for such  period  by
approximately  $2,283,000 (1.78%  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 $399,089 (.31% of Class B net assets
at that date). As of  July 31, 1994, direct cash  expenses for the period  since
the  commencement of operations  exceeded direct cash  revenues by approximately
$138,680 (.11% 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   the

                                       28
<PAGE>
Class  C shares, but not  the account maintenance fee.  The maximum sales charge
rule is applied separately to each class. As applicable to the Fund, the maximum
sales charge rule limits  the aggregate of distribution  fee payments and  CDSCs
payable  by the Fund to (1) 6.25% of  eligible gross sales of Class B shares and
Class C shares, computed separately  (defined to exclude shares issued  pursuant
to dividend reinvestments and exchanges) plus (2) interest on the unpaid balance
for  the respective class,  computed separately at  the prime rate  plus 1% (the
unpaid balance being the maximum amount payable minus amounts received from  the
payment  of the distribution fee  and the CDSC). In  connection with the Class B
shares, the Distributor has voluntarily agreed to waive interest charges on  the
unpaid  balance in  excess of 0.50%  of eligible gross  sales. Consequently, the
maximum amount  payable  to  the  Distributor (referred  to  as  the  "voluntary
maximum")  in connection  with the  Class B  shares is  6.75% of  eligible gross
sales. The Distributor retains the right to stop waiving the interest charges at
any time. To the  extent payments would exceed  the voluntary maximum, the  Fund
will  not make further payments of the  distribution fee with respect to Class B
shares and any CDSCs will  be paid to the Fund  rather than to the  Distributor;
however, the Fund will continue to make payments of the account maintenance fee.
In  certain circumstances the  amount payable pursuant  to the voluntary maximum
may exceed the  amount payable  under the  NASD formula.  In such  circumstances
payments  in excess  of the amount  payable under  the NASD formula  will not be
made.

                              REDEMPTION OF SHARES

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

REDEMPTION

    A shareholder wishing to redeem shares may do so without charge by tendering
the  shares  directly  to the  Transfer  Agent, 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 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

                                       29
<PAGE>
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 day received, and such request 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 of submitting 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 AND CLASS D SHARES

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

                                       30
<PAGE>
below  and instructions  as to  how to  participate in  the various  services or
plans, or to change options with respect thereto can be obtained from the  Trust
by calling the telephone number on the cover page hereof or from the Distributor
or Merrill Lynch.

    INVESTMENT   ACCOUNT.    Each  shareholder  whose  account  (an  "Investment
Account") is maintained at the Transfer Agent has an Investment Account and will
receive statements at least quarterly from the Transfer Agent. These  statements
will  serve as transaction confirmations  for automatic investment purchases and
the reinvestment  of  ordinary  income  dividends  and  long-term  capital  gain
distributions.  The statements will also show  any other activity in the account
since the preceding statement. Shareholders will receive separate  confirmations
for  each purchase or sale transaction other than automatic investment purchases
and the reinvestment of  ordinary income dividends  and long-term capital  gains
distributions. A shareholder may make additions to his Investment Account at any
time  by mailing a check  directly to the Transfer  Agent. Shareholders may also
maintain their accounts through Merrill Lynch.  Upon the transfer of shares  out
of  a Merrill Lynch brokerage account, an Investment Account in the transferring
shareholder's name will be opened automatically, without charge, at the Transfer
Agent. Shareholders considering  transferring their  Class A or  Class D  shares
from  Merrill Lynch to another brokerage firm or financial institution should be
aware that,  if the  firm to  which the  Class A  or Class  D shares  are to  be
transferred  will not take delivery of shares  of the Fund, a shareholder either
must redeem the Class A or Class  D shares (paying any applicable CDSC) so  that
the  cash proceeds  can be transferred  to the account  at the new  firm or such
shareholder must  continue to  maintain an  Investment Account  at the  Transfer
Agent  for  those  Class  A  or  Class  D  shares.  Shareholders  interested  in
transferring their Class B or Class C  shares from Merrill Lynch and who do  not
wish  to have an Investment  Account maintained for such  shares at the Transfer
Agent may request their new brokerage firm to maintain such shares in an account
registered in the name of the brokerage firm for the benefit of the  shareholder
at the Transfer Agent.

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

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

                                       31
<PAGE>
    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 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
funds  and the sales charge payable on the  shares of the Fund being acquired in
the exchange under the MFA program.

    AUTOMATIC REINVESTMENT OF  DIVIDENDS AND CAPITAL  GAINS DISTRIBUTIONS.   All
dividends  and capital gains distributions  are reinvested automatically in full
and fractional shares  of the Fund,  without a  sales charge, at  the net  asset
value  per share at the  close of business on the  monthly payment date for such
dividends  and  distributions.  A  shareholder  may  at  any  time,  by  written
notification  or by telephone  (1-800-MER-FUND) to the  Transfer Agent, elect to
have subsequent dividends or both dividends and capital gains distributions paid
in cash,  rather than  reinvested, in  which  event payment  will be  mailed  or
directly deposited monthly. Cash

                                       32
<PAGE>
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 Class A, Class B, Class C or
Class D may be made to an investor's Investment Account by pre-arranged  charges
of  $50  or more  to his  regular  bank account.  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 and  dealers to execute
portfolio transactions  for  the Fund.  The  portfolio securities  of  the  Fund
generally are traded on a net basis and normally do not involve either brokerage
commissions  or transfer taxes. The cost of portfolio securities transactions of
the Fund primarily  consists of dealer  or underwriter spreads.  Under the  1940
Act,  persons affiliated with the Trust, including Merrill Lynch, are prohibited
from dealing  with  the  Trust as  a  principal  in the  purchase  and  sale  of
securities  unless such trading is permitted by an exemptive order issued by the
Commission. The Trust has obtained an exemptive order permitting it to engage in
certain  principal  transactions  with  Merrill  Lynch  involving  high  quality
short-term municipal bonds subject to certain conditions. In addition, the Trust
may  not purchase securities, including Municipal Bonds, for the Fund during the
existence of  any underwriting  syndicate of  which Merrill  Lynch is  a  member
except pursuant to procedures approved by the Trustees of 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 close of  trading on the New  York Stock Exchange (currently  4:00
P.M.  New York time) 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.

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

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

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

TAXES

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

    To the extent that the dividends distributed to the Fund's Class A, Class B,
Class C and Class D shareholders (together, the "shareholders") are derived from
interest income  exempt from  Federal  tax under  Code  Section 103(a)  and  are
properly  designated as "exempt-interest  dividends" by the  Trust, they will be
excludable from a shareholder's  gross income for  Federal income tax  purposes.
Exempt-interest  dividends are included, however, in determining the portion, if
any, of a person's social security  and railroad retirement benefits subject  to
Federal  income  taxes.  The  portion  of  exempt-interest  dividends  paid from
interest received by  the Fund from  Pennsylvania Municipal Bonds  also will  be
exempt  from Pennsylvania personal income  tax. In the case  of residents of the
City of Philadelphia, distributions which are derived from interest received  by
the  Fund from Pennsylvania  Municipal Bonds or which  are designated as capital
gains dividends  for  Federal  income  tax purposes  will  be  exempt  from  the
Philadelphia  School  District investment  income  tax. Shareholders  subject to
income taxation by states other than Pennsylvania will realize a lower after-tax
rate of return than Pennsylvania shareholders since the dividends distributed by
the Fund generally

                                       34
<PAGE>
will not be  exempt, to  any significant degree,  from income  taxation by  such
other  states. The Trust will inform shareholders  annually as to the portion of
the distributions which  constitutes exempt-interest dividends  and the  portion
which   is  exempt  from   Pennsylvania  personal  income   taxes.  Interest  on
indebtedness incurred  or continued  to purchase  or carry  Fund shares  is  not
deductible  for  Federal  income  tax purposes  to  the  extent  attributable to
exempt-interest dividends. Persons who may  be "substantial users" (or  "related
persons"  of substantial users) of facilities financed by industrial development
bonds or  private activity  bonds held  by  the Fund  should consult  their  tax
advisers before purchasing Fund shares.

    It  is unclear at this time whether an investment in the Fund by a corporate
shareholder will qualify as an exempt asset for purposes of apportionment of the
Pennsylvania capital stock/foreign franchise tax. To the extent  exempt-interest
dividends  are excluded  from taxable  income for  Federal corporate  income tax
purposes  (determined  before   net  operating  loss   carryovers  and   special
deductions),  they will not be subject  to the Pennsylvania corporate net income
tax.

    Shares of the Fund will be exempt from Pennsylvania county personal property
taxes, the City of Pittsburgh personal  property tax and the School District  of
Pittsburgh  personal property tax to the  extent the Fund's portfolio securities
consist of Pennsylvania Municipal Bonds on the annual assessment date.

    To the extent that the Fund's distributions are derived from interest on its
taxable investments or from an excess  of net short-term capital gains over  net
long-term  capital losses  ("ordinary income dividends")  such distributions are
considered ordinary income for Federal  income tax purposes. 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. 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 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.  If the  Fund  pays a
dividend in January  which was  declared in  the previous  October, November  or
December  to shareholders of record  on a specified date  in one of such months,
then such dividend will be  treated for tax purposes as  being paid by the  Fund
and  received  by its  shareholders on  December 31  of the  year in  which such
dividend was declared.

    The  Code  subjects  interest  received  on  certain  otherwise   tax-exempt
securities to an alternative minimum tax. The alternative minimum tax applies to
interest  received  on "private  activity bonds"  issued  after August  7, 1986.
Private activity  bonds  are bonds  which,  although tax-exempt,  are  used  for
purposes  other than those  generally performed by  governmental units and which
benefit non-governmental entities (e.g.,  bonds used for industrial  development
or  housing purposes). Income received on such bonds is classified as an item of
"tax preference",  which  could  subject  investors  in  such  bonds,  including
shareholders  of the Fund, to an alternative minimum tax. The Fund will purchase
such "private activity bonds" and the Trust will report

                                       35
<PAGE>
to shareholders within 60 days after the Fund's taxable year-end the portion  of
the  Fund's dividends declared during the year  which constitutes an item of tax
preference for alternative minimum tax purposes. The Code further provides  that
corporations  are  subject to  an  alternative minimum  tax  based, in  part, on
certain differences between taxable income as adjusted for other tax preferences
and "adjusted  current earnings"  (which more  closely reflect  a  corporation's
economic  income). Because an exempt-interest dividend  paid by the Fund will be
included in adjusted current earnings,  a corporate shareholder may be  required
to pay alternative minimum tax on exempt-interest dividends paid by the Fund.

    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 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.

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

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

                                       36
<PAGE>
    Shareholders  are  urged  to  consult  their  tax  advisers  regarding   the
availability  of  any exemption  from  state or  local  taxes and  with specific
questions as to Federal, foreign, state or local taxes.

                                PERFORMANCE DATA

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

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

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

    Yield  quotations will be computed based on  a 30-day period by dividing (a)
the net income based on the yield  of each security earned during the period  by
(b)  the average daily number of shares  outstanding during the period that were
entitled to receive dividends multiplied by the maximum offering price per share
on the

                                       37
<PAGE>
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 5.08%  for Class  A shares and  4.78% for  Class B shares  and the  tax
equivalent yield for the same period (based on a Federal income tax rate of 28%)
was 7.06% for Class A shares and 6.64% 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 gains or losses during the period. The value
of an  investment in  the Fund  will fluctuate  and an  investor's shares,  when
redeemed, may be worth more or less than their original cost.

    On  occasion,  the  Fund may  compare  its performance  to  performance data
published by Lipper  Analytical Services, Inc.,  Morningstar Publications,  Inc.
("Morningstar")  and CDA  Investment Technology,  Inc. or  to data  contained in
publications such as MONEY  MAGAZINE, U.S. NEWS &  WORLD REPORT, BUSINESS  WEEK,
FORBES  MAGAZINE and FORTUNE MAGAZINE.  From time to time,  the Fund may include
the Fund's Morningstar  risk-adjusted performance ratings  in advertisements  or
supplemental  sales  literature.  As with  other  performance  data, performance
comparisons should  not  be considered  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
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  Class A shares  will generally be higher
than the per share net  asset value of shares  of the other classes,  reflecting
the  daily expense accruals of the  account maintenance and transfer agency fees
applicable with respect to the Class B and Class C shares and the daily  expense
accruals  of the  account maintenance  fees applicable  with respect  to Class D
shares. Moreover, the per share net asset value of the Class D shares  generally
will  be higher than the  per share net asset  value of the Class  B and Class C
shares,  reflecting  the  daily  expense  accruals  of  the  distribution   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

                                       38
<PAGE>
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, Class B, Class C and Class D shares. Class
A, Class B, Class C and Class D shares represent interests in the same assets of
the Fund and  are identical in  all respects except  that Class B,  Class C  and
Class  D  shares  bear  certain  expenses  related  to  the  account maintenance
associated with  such  shares, and  Class  B and  Class  C shares  bear  certain
expenses  related to the  distribution of such shares.  Each class has exclusive
voting rights  with  respect to  matters  relating to  account  maintenance  and
distribution expenditures as applicable. See "Purchase of Shares". The Trust has
received  an  order from  the  Commission permitting  the  issuance and  sale of
multiple classes  of  shares.  The  Trustees  of  the  Trust  may  classify  and
reclassify the shares of the Trust into additional classes at a future date.

    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, Class  B, Class C  and Class D  shares
bear   certain  additional  expenses.  The  obligations  and  liabilities  of  a
particular Series are restricted to the assets of that Series and do not  extend
to  the assets of the  Trust generally. The shares  of each Series, when issued,
will be fully-paid and non-assessable by the Trust.

SHAREHOLDER REPORTS

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

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

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

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

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

    Merrill  Lynch Pennsylvania Municipal Bond Fund  (the "Fund") is a series of
Merrill Lynch  Multi-State Municipal  Series Trust  (the "Trust"),  an  open-end
management  investment company organized as  a Massachusetts business trust. The
investment objective of the Fund is to provide shareholders with as high a level
of income  exempt from  Federal and  Pennsylvania personal  income taxes  as  is
consistent  with prudent investment management. The  Fund invests primarily in a
portfolio of long-term  investment grade  obligations the interest  on which  is
exempt  from Federal  and Pennsylvania personal  income taxes in  the opinion of
bond counsel to  the issuer ("Pennsylvania  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
the investor expects to hold the shares and other relevant circumstances.

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

    This Statement of Additional Information of the Fund is not a prospectus and
should be read in conjunction with the prospectus of the Fund, dated October 21,
1994  (the "Prospectus"), which has been  filed with the Securities and Exchange
Commission (the "Commission") and can be obtained, without charge, by calling or
by writing the Fund at the above telephone number or address. This Statement  of
Additional Information has been incorporated by reference into the Prospectus.

                       INVESTMENT OBJECTIVE AND POLICIES

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

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

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

    Except when  acceptable  securities are  unavailable  as determined  by  the
Manager,  the Fund will  under normal circumstances  invest at least  65% of its
total assets  in  Pennsylvania Municipal  Bonds.  For temporary  periods  or  to
provide  liquidity, the Fund has  the authority to invest as  much as 35% of its
assets in tax-exempt or taxable money market obligations with a maturity of  one
year or less (such short-term obligations being referred to herein as "Temporary
Investments"),  except that  taxable Temporary  Investments, together  with such
other instruments as are not exempt from Pennsylvania taxation, shall not exceed
20% of the Fund's

                                       2
<PAGE>
total assets. The Fund  at all times will  have at least 80%  of its net  assets
invested  in securities exempt from Federal taxation. However, interest received
on certain  otherwise tax-exempt  securities which  are classified  as  "private
activity  bonds" (in general, bonds  that benefit non-governmental entities) may
be subject to  an alternative minimum  tax. The Fund  may purchase such  private
activity  bonds. See "Distributions  and Taxes." In  addition, the Fund reserves
the right to  invest temporarily a  greater portion of  its assets in  Temporary
Investments for defensive purposes, when, in the judgment of the Manager, market
conditions  warrant. The investment  objective of the Fund  and the policies set
forth in this paragraph are  fundamental policies of the  Fund which may not  be
changed  without a vote of a majority of the outstanding shares of the Fund. The
Fund's hedging strategies are  not fundamental policies and  may be modified  by
the Trustees of the Trust without the approval of the Fund's shareholders.

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

    The Fund may invest  in Municipal Bonds  the return on which  is based on  a
particular index of value or interest rates. For example, the Fund may invest in
Municipal  Bonds that pay interest based on  an index of Municipal Bond interest
rates or based  on the  value of  gold or  some other  commodity. The  principal
amount payable upon maturity of certain Municipal Bonds also may be based on the
value  of an index. To  the extent the Fund invests  in these types of Municipal
Bonds, the Fund's return on  such Municipal Bonds will  be subject to risk  with
respect  to the  value of  the particular  index. 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. 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 10% 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

                                       3
<PAGE>
require  a mandatory tender for the purchase of related Municipal Bonds, subject
to certain conditions. A Call Right that is not exercised prior to the  maturity
of  the related Municipal Bond will expire without value. The economic effect to
holding both  the Call  Right and  the related  Municipal Bond  is identical  to
holding a Municipal Bond as a non-callable security. Certain investments in such
obligations  may  be  illiquid.  The  Fund  may  not  invest  in  such  illiquid
obligations if such investments, together with other illiquid investments, would
exceed 10% 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

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

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

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

            DESCRIPTION OF MUNICIPAL BONDS AND TEMPORARY INVESTMENTS

    Set  forth  below is  a  description of  the  Municipal Bonds  and Temporary
Investments in which the Fund may invest. A more complete discussion  concerning
futures  and options transactions  is set forth  under "Investment Objective and
Policies" in the  Prospectus. Information  with respect to  ratings assigned  to
tax-exempt  obligations which the Fund may purchase  is set forth in Appendix II
to this Statement of Additional Information.

DESCRIPTION OF MUNICIPAL BONDS

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

    The   two  principal   classifications  of  Municipal   Bonds  are  "general
obligation" and "revenue"  bonds which  latter category includes  IDBs and,  for
bonds  issued after August 15, 1986,  private activity bonds. General obligation
bonds are secured by the issuer's pledge  of faith, credit and taxing power  for
the  payment of principal and interest. Revenue  bonds are payable only from the
revenues derived from a particular facility  or class of facilities or, in  some
cases,  from  the  proceeds  of  a special  or  limited  tax  or  other specific

                                       5
<PAGE>
revenue source such as from the user  of the facility being financed. IDBs  and,
in  the case of bonds issued after  August 15, 1986, private activity bonds, are
in most cases revenue bonds  and generally do not  constitute the pledge of  the
credit  or taxing power of  the issuer of such  bonds. Generally, the payment of
the principal of and interest on such bonds depends solely on the ability of the
user of the facility financed by the bonds to meet its financial obligations and
the pledge, if any, of  real and personal property  so financed as security  for
such  payment, unless  a line  of credit,  bond insurance  or other  security is
furnished. The  Fund also  may invest  in "moral  obligation" bonds,  which  are
normally  issued by special purpose public authorities. Under a moral obligation
bond, if an issuer of moral obligation bonds is unable to meet its  obligations,
the  repayment  of  such bonds  becomes  a  moral commitment,  but  not  a legal
obligation, of the state or municipality in question.

    Also  included  within   the  general  category   of  Municipal  Bonds   are
participation  certificates  issued  by government  authorities  or  entities to
finance the acquisition  or construction of  equipment, land and/or  facilities.
The  certificates represent participations  in a lease,  an installment purchase
contract or a conditional sales contract (hereinafter collectively called "lease
obligations") relating to  such equipment,  land or  facilities. Although  lease
obligations  do not constitute  general obligations of the  issuer for which the
issuer's unlimited taxing  power is  pledged, a lease  obligation is  frequently
backed by the issuer's covenant to budget for, appropriate and make the payments
due  under the lease obligation. Certain investments in lease obligations may be
illiquid. The  Fund  may  not  invest in  illiquid  lease  obligations  if  such
investments,  together with all other illiquid  investments, would exceed 10% 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 to  be
liquid if they are publicly offered and have received an investment grade rating
of  Baa or better  by Moody's, or BBB  or better by Standard  & Poor's or Fitch.
Unrated lease  obligations,  or those  rated  below investment  grade,  will  be
considered  liquid if the obligations come to the market through an underwritten
public offering and at least two  dealers are willing to give competitive  bids.
In  reference to the latter,  the Manager must, among  other things, also review
the creditworthiness of  the municipality  obligated to make  payment under  the
lease obligation and make certain specified determinations based on such factors
as  the  existence of  a rating  or  credit enhancement  such as  insurance, the
frequency of trades or quotes for the obligation and the willingness of  dealers
to make a market in the obligation.

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

DESCRIPTION OF TEMPORARY INVESTMENTS

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

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

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

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

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

    The  Trust has  established the  following standards  with respect  to money
market securities in which the Fund invests. Commercial paper investments at the
time of purchase must be rated "A-1" through "A-3" by

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

REPURCHASE AGREEMENTS

    The Fund  may  invest  in  securities  pursuant  to  repurchase  agreements.
However,  any transaction involving repurchase  agreements will be in accordance
with the Fund's investment policies  and limitations. See "Investment  Objective
and   Policies  --  Investment  Restrictions"   in  the  Prospectus.  Repurchase
agreements and  purchase and  sale contracts  may be  entered into  only with  a
member bank of the Federal Reserve System or a primary dealer in U.S. Government
securities  or an affiliate  thereof. Under such  agreements, the seller agrees,
upon entering into the contract, to repurchase  the security from the Fund at  a
mutually  agreed upon time  and price, thereby determining  the yield during the
term of the agreement.  This results in  a fixed rate  of return insulated  from
market  fluctuations during such  period. In 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, instead of the contractual
fixed rate of return, the rate of return to the Fund will depend on  intervening
fluctuations  of the market value  of such security and  the accrued interest on
the security. In such event, the Fund  would have rights against the seller  for
breach  of contract with respect to  any losses arising from market fluctuations
following the failure  of the  seller to  perform. The  Fund may  not invest  in
repurchase  agreements maturing  in more  than seven  days if  such investments,
together with other  illiquid securities,  would exceed  10% of  the Fund's  net
assets.

    In  general, for  Federal and  Pennsylvania income  tax purposes, repurchase
agreements are treated as collateralized loans secured by the securities "sold."
Therefore,  amounts  earned  under  such  agreements  will  not  be   considered
tax-exempt interest.

FINANCIAL FUTURES TRANSACTIONS AND OPTIONS

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

                                       8
<PAGE>
    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 purchase realizes a loss or gain. In addition, a
nominal commission is paid on each completed sale transaction.

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

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

                                       9
<PAGE>
    As described in  the Prospectus, the  Fund may purchase  and sell  financial
futures  contracts  on U.S.  Government securities  as  a hedge  against adverse
changes in interest rates  as described below. With  respect to U.S.  Government
securities,  currently there are financial  futures contracts based on long-term
U.S. Treasury bonds,  Treasury notes, Government  National Mortgage  Association
Certificates  and three-month  U.S. Treasury  bills. The  Fund may  purchase and
write call and put options on futures contracts on U.S. Government securities in
connection with its hedging strategies.

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

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

    When  the Fund  intends to purchase  Municipal Bonds, the  Fund may purchase
futures contracts as a hedge against any increase in the cost of such  Municipal
Bonds, resulting from 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. However, any transactions involving call and put  options
on  futures contracts will be in  accordance with the Fund's investment policies
and limitations. See "Investment Objective and Policies-Investment Restrictions"
in the  Prospectus. The  purchase of  a call  option on  a futures  contract  is
analogous  to the purchase of a call option on an individual security. Depending
on the pricing of the option compared to either the futures contract on which it
is based,

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

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

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

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

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

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

    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.

                                       11

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

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

    The Fund expects to liquidate a majority of the futures contracts it  enters
into  through offsetting transactions  on the applicable  contract market. There
can be no assurance, however, that a liquid secondary market will exist for  any
particular  futures contract at any specific time.  Thus, it may not be possible
to close out a futures  position. In the event  of adverse price movements,  the
Fund  would continue  to be  required to 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 in 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 or Municipal  Bonds);
(3)  invest more than 5% 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,  including predecessors,  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  of  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), or  interests  or leases  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 would not apply to options on financial futures
contracts); (9) make loans to other persons,

                                       13
<PAGE>
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 with
legal or contractual restrictions  on resale or for  which no readily  available
market  exists,  or in  individually negotiated  loans that  constitute illiquid
investments and lease obligations, or  in repurchase agreements or purchase  and
sale  contracts  maturing  in  more  than seven  days,  if,  regarding  all such
securities, more than 10% 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 (the
"Securities Act"), in selling portfolio securities.

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

    PROPOSED UNIFORM  INVESTMENT RESTRICTIONS.  As discussed  in the  Prospectus
under  "Investment Objective and Policies -- Investment Restrictions", the Board
of Trustees of  the Trust 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 FAM
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 Fund  are currently considering  whether to approve the
proposed revised  investment  restrictions.  If  such  shareholder  approval  is
obtained,  the Fund's  current investment restrictions  will be  replaced by the
proposed restrictions, and  the Fund's  Prospectus and  Statement of  Additional
Information will be supplemented to reflect such change.

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

        1.   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 1940  Act) in  amounts up  to 33  1/3% of  its total  assets
    (including  the  amount  borrowed),  (ii)  the  Fund  may  borrow  up  to an
    additional 5% of its total assets for temporary purposes, (iii) the Fund may
    obtain such  short-term credit  as may  be necessary  for the  clearance  of
    purchases  and sales of portfolio securities  and (iv) the Fund may purchase
    securities on margin to the extent permitted by applicable law. The Fund may
    not pledge its assets other than to secure such borrowings or, to the extent
    permitted by the Fund's investment policies  as set forth in its  Prospectus
    and Statement of Additional Information, as they may be amended from time to
    time,  in connection with hedging transactions, short sales, when-issued and
    forward commitment transactions and similar investment strategies.

        7.  Underwrite securities  of other issuers except  insofar as the  Fund
    technically may be deemed an underwriter under the Securities Act 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 the Fund's net assets, are warrants which are not listed on the New  York
    Stock  Exchange or American Stock Exchange  or a major foreign exchange. For
    purposes of this  restriction, warrants  acquired by  the Fund  in units  or
    attached to securities may be deemed to be without value.

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

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

    Because  of  the  affiliation  of  Merrill  Lynch,  Pierce,  Fenner  & Smith
Incorporated ("Merrill  Lynch") with  the Trust,  the Trust  is prohibited  from
engaging  in certain transactions  involving Merrill Lynch  except pursuant to a
permissive order or otherwise in compliance with the provisions of the 1940  Act
and the rules

                                       16
<PAGE>
and  regulations  thereunder. Included  among  such restricted  transactions are
purchases from or sales to Merrill Lynch of securities in transactions in  which
it acts as principal and purchases of securities from
underwriting syndicates of which Merrill Lynch is a member.

(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 September 30, 1994, the Trustees and officers of the Trust as a group (12
persons)  owned an aggregate of less than 1% of the outstanding shares of Common
Stock of ML  & Co. and  owned an aggregate  of less than  1% of the  outstanding
shares of the Fund.

    The Trust pays each Trustee not affiliated with the Manager a fee of $10,000
per  year plus $1,000 per meeting  attended, together with such Trustee's actual
out-of-pocket expenses  relating  to  attendance at  meetings.  The  Trust  also
compensates  members  of its  Audit 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 $6,324 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 the  Manager or its  affiliates purchase or  sell
securities  for the  Fund or other  funds for which  they act as  manager or for
their advisory  clients arise  for  consideration at  or  about the  same  time,
transactions  in  such securities  will be  made, insofar  as feasible,  for the
respective funds and clients in a manner deemed

                                       18
<PAGE>
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 period  August 31, 1990,  the
Fund's commencement of operations, to July 31, 1991, the Fund's fiscal year end,
the total advisory fees payable to the Manager aggregated $118,779. For the year
ended  July 31, 1993,  the total advisory fees  paid by the  Fund to the Manager
aggregated $591,807, of which $130,342 was  waived. For the year ended July  31,
1994,  the total  advisory fees  payable by the  Fund to  the Manager aggregated
$852,481.

    California imposes limitations  on the  expenses of the  Fund. These  annual
expense  limitations require  that the Manager  reimburse the Fund  in an amount
necessary to prevent the aggregate ordinary operating expenses (excluding taxes,
brokerage fees and commissions, distribution fees and extraordinary charges such
as litigation costs) from exceeding in any fiscal year 2.5% of the Fund's  first
$30,000,000  of average net assets, 2.0% of  the next $70,000,000 of average net
assets and 1.5% of the remaining average net assets. The Manager's obligation to
reimburse the Fund is limited to the amount of the management fee. Expenses  not
covered  by the limitation are interest,  taxes, brokerage commissions and other
items such as extraordinary legal expenses. No  fee payment will be made to  the
Manager  during any fiscal year which will cause such expenses to exceed expense
limitations at the time of such payment. No fee reimbursements were made  during
the  period August 31, 1990, the Fund's  commencement of operations, to July 31,
1992, the Fund's fiscal year  end, or during the years  ended July 31, 1993  and
1994 pursuant to these operating expense limitations.

    The  Management  Agreement  obligates  the  Manager  to  provide  investment
advisory services and to  pay all compensation of  and furnish office space  for
officers  and  employees of  the Trust  connected  with investment  and economic
research, trading  and  investment management  of  the  Trust, as  well  as  the
compensation  of all  Trustees of  the Trust who  are affiliated  persons of the
Manager or any of its subsidiaries. The Fund pays all other expenses incurred in
its operation and, if other Series shall  be added ("Series"), a portion of  the
Trust's  general administrative expenses  will be allocated on  the basis of the
asset size of the respective Series. Expenses that will be borne directly by the
Series include, among other things,  redemption expenses, expenses of  portfolio
transactions,  expenses  of  registering  the  shares  under  Federal  and state
securities laws, pricing  costs (including  the daily calculation  of net  asset
value), expenses of printing shareholder reports, prospectuses and statements of
additional  information  (except  to  the  extent  paid  by  the  Distributor as
described below),  fees  for  legal  and  auditing  services,  Commission  fees,
interest, certain taxes, and other expenses attributable to a particular Series.
Expenses  which will be allocated  on the basis of  asset size of the respective
Series include  fees  and expenses  of  unaffiliated Trustees,  state  franchise
taxes,  costs  of printing  proxies and  other  expenses related  to shareholder
meetings, and other expenses properly  payable by the Trust. The  organizational
expenses of the Trust were paid by the Trust, and if additional Series are added
to  the  Trust,  the  organizational expenses  are  allocated  among  the Series
(including the Fund)  in a manner  deemed equitable by  the Trustees.  Depending
upon  the nature of a lawsuit, litigation  costs may be assessed to the specific
Series to which the lawsuit relates or allocated on the basis of the asset  size
of the respective

                                       19
<PAGE>
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, 1993, the Fund reimbursed the Manager
$58,164  for  accounting  services.  As  required  by  the  Fund's  distribution
agreements,  the  Distributor  will pay  the  promotional expenses  of  the Fund
incurred in connection with the offering of shares of the Fund. Certain expenses
in connection with the  account maintenance and distribution  of Class B  shares
will  be financed by  the Fund pursuant  to the Distribution  Plan in compliance
with Rule 12b-1  under the  1940 Act. See  "Purchase of  Shares --  Distribution
Plan".

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

    DURATION AND TERMINATION. Unless earlier terminated as described herein, the
Management Agreement  will  remain in  effect  from  year to  year  if  approved
annually  (a) by the Trustees  of the Trust or by  a majority of the outstanding
shares of the Fund and (b) by a majority of the Trustees who are not parties  to
such  contract or interested  persons (as defined  in the 1940  Act) of any such
party. Such contracts are not assignable  and may be terminated without  penalty
on  60 days' written notice at the option  of either party thereto or by vote of
the shareholders of the Fund.

                               PURCHASE OF SHARES

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

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

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

    The  Fund has  entered into four  separate distribution  agreements with the
Distributor in connection with the continuous  offering of each class of  shares
of  the  Fund  (the  "Distribution  Agreements").  The  Distribution  Agreements
obligate the Distributor to pay certain expenses in connection with the offering
of each  class of  shares of  the Fund.  After the  prospectuses, statements  of
additional  information and periodic reports have been prepared, set in type and
mailed to shareholders, the Distributor  pays for the printing and  distribution
of  copies  thereof  used  in  connection  with  the  offering  to  dealers  and
prospective investors. The

                                       20
<PAGE>
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 August  31,
1990.  The gross  sales charges for  the sale of  Class A shares  for the period
August 31, 1990,  the Fund's commencement  of operations to  July 31, 1991,  the
Fund's  fiscal year end, were $168,998, of which the Distributor received $7,295
and Merrill Lynch  received $161,703. The  gross sales charges  for the sale  of
Class  A shares for  the fiscal year July  31, 1992 were  $128,234, of which the
Distributor received $9,777 and Merrill Lynch received $118,457. The gross sales
charges for the sale  of Class A shares  for the year ended  July 31, 1993  were
$113,436  of which  the Distributor received  $6,558 and  Merrill Lynch received
$106,848. The gross sales charges  for the sale of Class  A shares for the  year
ended  July 31, 1994 were $93,697, of  which the Distributor received $8,083 and
Merrill Lynch received $85,614.

    The term  "purchase",  as used  in  the  Prospectus and  this  Statement  of
Additional  Information in connection with an investment  in Class A and Class D
shares of  the  Fund, refers  to  a single  purchase  by an  individual,  or  to
concurrent  purchases,  which  in  the  aggregate  are  at  least  equal  to the
prescribed amounts, by an  individual, his spouse and  their children under  the
age  of 21 years  purchasing shares for his  or their own  account and to single
purchases by a trustee or other  fiduciary purchasing shares for a single  trust
estate  or  single  fiduciary  account although  more  than  one  beneficiary is
involved. The term "purchase" also includes purchases by any "company", as  that
term  is defined  in the 1940  Act, but does  not include purchases  by any such
company which has not been in existence for at least six months or which has  no
purpose  other  than the  purchase  of shares  of the  Fund  or shares  of other
registered investment companies at a discount; provided, however, that it  shall
not  include purchases  by any  group of  individuals whose  sole organizational
nexus is that  the participants  therein are  credit cardholders  of a  company,
policyholders   of  an  insurance  company,  customers   of  either  a  bank  or
broker-dealer or clients of an investment adviser.

    CLOSED-END  INVESTMENT  OPTION.  Class  A  shares  of  the  Fund  and  other
MLAM-advised  mutual funds ("Eligible Class A  shares") are offered at net asset
value to shareholders of certain closed-end funds advised by the Manager or MLAM
who purchased such closed-end fund shares prior to October 21, 1994 and wish  to
reinvest  the net proceeds of  a sale of their  closed-end fund shares of common
stock in  Eligible  Class  A shares,  if  the  conditions set  forth  below  are
satisfied. Alternatively, closed-end fund shareholders who purchased such shares
on  or after October 21, 1994 and wish  to reinvest the net proceeds from a sale
of their closed-end fund shares are offered  Class A shares (if eligible to  buy
Class  A shares)  or Class D  shares of  the Fund and  other MLAM-advised mutual
funds ("Eligible Class D Shares"), if  the following conditions are met.  First,
the  sale of closed-end fund shares must  be made through Merrill Lynch, and the
net proceeds therefrom  must be immediately  reinvested in Eligible  Class A  or
Class  D  shares.  Second, the  closed-end  fund  shares must  either  have been
acquired in the initial public offering or be shares representing dividends from
shares of common  stock acquired in  such offering. Third,  the closed-end  fund
shares  must have  been continuously  maintained in  a Merrill  Lynch securities
account. Fourth, there must be a minimum purchase of $250 to be eligible for the
investment option. Class A shares of the Fund are offered at net asset value  to
shareholders  of Merrill Lynch Senior Floating Rate Fund, Inc. ("Senior Floating
Rate Fund") who  wish to reinvest  the net proceeds  from a sale  of certain  of
their shares of common stock of Senior Floating Rate Fund in shares of the Fund.
In  order  to  exercise  this  investment  option,  Senior  Floating  Rate  Fund

                                       21
<PAGE>
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  shares
of  the Fund subject to an initial sales charge at the offering price applicable
to the total of (a) the public offering price of the shares then being purchased
plus (b) an amount equal to the then current net asset value or cost,  whichever
is  higher, of the purchaser's combined holdings of all classes of shares of the
Fund and of other MLAM-advised mutual funds. For any such right of  accumulation
to  be made available, the Distributor must be provided at the time of purchase,
by  the  purchaser  or  the  purchaser's  securities  dealer,  with   sufficient
information  to permit confirmation of qualification. Acceptance of the purchase
order is subject to such confirmation. The right of accumulation may be  amended
or  terminated at any  time. Shares held in  the name of  a nominee or custodian
under pension,  profit-sharing,  or other  employee  benefit plans  may  not  be
combined with other shares to qualify for the right of accumulation.

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

                                       22
<PAGE>
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  Merrill  Lynch
Government Fund, Merrill Lynch Institutional Fund, Merrill Lynch Treasury  Fund,
Merrill  Lynch Ready Assets Trust, Merrill Lynch Retirement Reserves Money Fund,
Merrill Lynch Institutional Tax-Exempt Fund,  Merrill Lynch Treasury Money  Fund
or  Merrill Lynch U.S.A. Government Reserves 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 at net  asset value to
TMA-SM-  Managed  Trusts   to  which  Merrill   Lynch  Trust  Company   provides
discretionary trustee services at net asset value.

    PURCHASE  PRIVILEGES OF CERTAIN  PERSONS. Trustees of  the Trust, members of
the Boards  of  other  MLAM-advised  investment companies,  ML  &  Co.  and  its
subsidiaries  (the term  "subsidiaries", when used  herein with respect  to ML &
Co.,  includes  MLAM,  the  Manager  and  certain  other  entities  directly  or
indirectly  wholly-owned and  controlled by  ML &  Co.) and  their directors and
employees and any trust, pension, profit-sharing or other benefit plan for  such
persons, may purchase Class A shares of the Fund at net asset value.

    Class D shares of the Fund will be offered at net asset value, without sales
charge,  to  an  investor  who  has a  business  relationship  with  a financial
consultant who  joined Merrill  Lynch from  another investment  firm within  six
months  prior  to  the date  of  purchase  by such  investor,  if  the following
conditions are satisfied. First, the investor must advise Merrill Lynch that  it
will  purchase Class D shares  of the Fund with proceeds  from a redemption of a
mutual fund that was sponsored by  the financial consultant's previous firm  and
was  subject to a sales charge  either at the time of  purchase or on a deferred
basis. Second, the investor  also must establish that  such redemption had  been
made  within 60 days prior to the investment  in the Fund, and the proceeds from
the redemption had  been maintained in  the interim  in cash or  a money  market
fund.

    Class  D shares  of the Fund  are also  offered at net  asset value, without
sales charge, to  an investor  who has a  business relationship  with a  Merrill
Lynch  financial consultant and who has invested in a mutual fund 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 on a deferred basis.
Second, such purchase of Class D shares  must be made within 90 days after  such
notice.

    Class  D shares of  the Fund will be  offered at net  asset value, without 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

                                       23
<PAGE>
the  assets or  company acquired  in a tax-free  transaction may  be adjusted in
appropriate cases to reduce possible adverse tax consequences to the Fund  which
might  result from an  acquisition of assets  having net unrealized appreciation
which is disproportionately higher at the time of acquisition than the  realized
or  unrealized appreciation  of the  Fund. The  issuance of  Class D  shares for
consideration other than cash is limited to bona fide reorganizations, statutory
mergers or  other  acquisitions  of  portfolio securities  which  (i)  meet  the
investment objectives and policies of the Fund; (ii) are acquired for investment
and  not for resale  (subject to the  understanding that the  disposition of the
Fund's portfolio securities shall at all  times remain within its control);  and
(iii)  are liquid securities, the value of which is readily ascertainable, which
are not restricted as to transfer either  by law or liquidity of market  (except
that  the  Fund may  acquire through  such  transactions restricted  or illiquid
securities to  the extent  the Fund  does not  exceed the  applicable limits  on
acquisition  of  such  securities  set  forth  under  "Investment  Objective and
Policies" herein).

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

DISTRIBUTION PLANS

    Reference  is  made to  "Purchase of  Shares --  Distribution Plans"  in the
Prospectus for certain  information with  respect to  the separate  distribution
plans  for Class B, Class C and Class  D shares pursuant to Rule 12b-1 under the
1940 Act (each a  "Distribution Plan") with respect  to the account  maintenance
and/or  distribution fees paid  by the Fund  to the Distributor  with respect to
such classes.

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

LIMITATIONS ON THE PAYMENT OF DEFERRED SALES CHARGES

    The maximum sales charge rule in the Rules of Fair Practice of the  National
Association of Securities Dealers, Inc. ("NASD") imposes a limitation on certain
asset-based sales charges such as the distribution fee

                                       24
<PAGE>
and  the  CDSC borne  by the  Class B  and Class  C shares  but not  the account
maintenance fee. The  maximum sales charge  rule is applied  separately to  each
class.  As applicable  to the  Fund, the  maximum sales  charge rule  limits the
aggregate of distribution  fee payments  and CDSCs payable  by the  Fund to  (1)
6.25%  of eligible gross  sales of Class  B shares and  Class C shares, computed
separately (defined to exclude shares issued pursuant to dividend  reinvestments
and  exchanges),  plus (2)  interest on  the unpaid  balance for  the respective
class, computed separately, at the prime rate plus 1% (the unpaid balance  being
the  maximum  amount payable  minus  amounts received  from  the payment  of the
distribution fee  and the  CDSC). In  connection with  the Class  B shares,  the
Distributor  has  voluntarily agreed  to waive  interest  charges on  the unpaid
balance in excess of  0.50% of eligible gross  sales. Consequently, the  maximum
amount  payable to the  Distributor (referred to as  the "voluntary maximum") in
connection with  the  Class B  shares  is 6.75%  of  eligible gross  sales.  The
Distributor  retains the right to stop waiving the interest charges at any time.
To the extent  payments would exceed  the voluntary maximum,  the Fund will  not
make  further payments of the  distribution fee with respect  to Class B shares,
and any CDSCs will be paid to the Fund rather than to the Distributor;  however,
the  Fund will  continue to  make payments  of the  account maintenance  fee. In
certain circumstances the amount payable  pursuant to the voluntary maximum  may
exceed  the amount payable under the NASD formula. In such circumstances payment
in excess of the amount payable under the NASD formula will not be made.

    The following table sets forth comparative  information as of July 31,  1994
with  respect to the Class B shares of the Fund indicating the maximum allowable
payments that can  be made  under the  NASD maximum  sales charge  rule and  the
Distributor's   voluntary   maximum   for   the   period   September   4,   1990
(commencement of the public offering of Class B shares) to 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 Internal Revenue  Code of 1986,  as amended (the
"Code")) of a Class B shareholder (including one who owns the Class B shares  as
joint  tenant  with his  or her  spouse), provided  the redemption  is requested
within one year  of the death  or initial determination  of disability. For  the
fiscal  years ended July 31, 1992, 1993, and 1994 the Distributor received CDSCs
of $73,733,  $114,196 and  $204,747,  respectively, all  of  which was  paid  to
Merrill Lynch.

                             PORTFOLIO TRANSACTIONS

    Reference  is made to "Investment Objective and Policies -- Other Investment
Policies and Practices" in the Prospectus.

    Under the 1940 Act,  persons affiliated with the  Trust are prohibited  from
dealing  with the  Fund as 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 period August  31, 1990, the Fund's commencement of
operations, to July 31, 1991, the Fund's fiscal year end, the Fund engaged in no
transactions pursuant to such  order. For the fiscal  year ended July 31,  1992,
the  Fund engaged in no transactions pursuant  to such order. For the year ended
July 31, 1993, the Fund engaged in  two transactions pursuant to such order  for
an  aggregate market value of $1,003,147. For  the year ended July 31, 1994, the
Fund engaged in one transaction pursuant  to such order for an aggregate  market
value  of $602,352. Affiliated persons of the  Trust may serve as broker for the
Fund in  over-the-counter transactions  conducted on  an agency  basis.  Certain
court  decisions  have raised  questions as  to the  extent to  which investment
companies should  seek  exemptions  under the  1940  Act  in order  to  seek  to
recapture underwriting and dealer spreads from affiliated entities. The Trustees
have  considered all factors deemed relevant,  and have made a determination not
to seek such recapture  at this time. The  Trustees will reconsider this  matter
from time to time.

                                       26
<PAGE>
    Under  the  1940  Act,  the  Fund  may  not  purchase  securities  from  any
underwriting syndicate of which Merrill Lynch is a member except pursuant to  an
exemptive  order or rules adopted  by the Commission. Rule  10f-3 under the 1940
Act sets forth conditions under which  the Fund may purchase municipal bonds  in
such  transactions. The  rule sets forth  requirements relating  to, among other
things, the terms  of an issue  of municipal  bonds purchased by  the Fund,  the
amount of municipal bonds which may be purchased in any one issue and the assets
of the Fund which may be invested in a particular issue.

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

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

    Generally, the  Fund does  not purchase  securities for  short-term  trading
profits.  However, the Fund may dispose of securities without regard to the time
they have been held  when such action, for  defensive or other reasons,  appears
advisable  to its Manager.  While it is  not possible to  predict turnover rates
with any  certainty,  at  present  it is  anticipated  that  the  Fund's  annual
portfolio  turnover rate, under normal  circumstances after the Fund's portfolio
is invested in accordance with its investment objective, will be less than 100%.
(The portfolio turnover rate is calculated  by dividing the lesser of  purchases
or  sales of portfolio securities for the  particular fiscal year by the monthly
average of the value of  the portfolio securities owned  by the Fund during  the
particular  fiscal year. For  purposes of determining  this rate, all securities
whose maturities at the time of acquisition are one year or less are  excluded.)
The  portfolio  turnover for  the period  August 30,  1990 (the  commencement of
operations) to July 31, 1991 was 0%. The portfolio turnover for the fiscal years
ended July 31, 1992, 1993 and 1994 were 4.14%, 9.69% and 37.73%, respectively.

    Section 11(a) of the Securities Exchange Act of 1934, as amended,  generally
prohibits  members  of the  U.S.  national securities  exchanges  from executing
exchange transactions for their affiliates and institutional accounts which they
manage unless the member (i) has  obtained prior express authorization from  the
account  to  effect  such transactions,  (ii)  at least  annually  furnishes the
account with a statement  setting forth the  aggregate compensation received  by
the member in effecting such transactions, and (iii) complies with any rules the
Commission  has prescribed with  respect to the requirements  of clauses (i) and
(ii). To the  extent Section  11(a) would  apply to  Merrill Lynch  acting as  a
broker  for the Fund in  any of its portfolio  transactions executed on any such
securities exchange of  which it  is a  member, appropriate  consents have  been
obtained  from the Fund and annual  statements as to aggregate compensation will
be provided to the Fund.

                        DETERMINATION OF NET ASSET VALUE

    The net asset value of the shares  of all classes of the Fund is  determined
once  daily, Monday through Friday, as of 4:15  P.M., New York time, on each day
during which the New York Stock Exchange is open for

                                       27
<PAGE>
trading. The New York Stock Exchange is not open on New Year's Day,  Presidents'
Day,  Good Friday, Memorial  Day, Independence Day,  Labor Day, Thanksgiving Day
and Christmas Day. Net asset value per share is computed by dividing the sum  of
the value of the securities held by the Fund plus any cash or other assets minus
all  liabilities by the total number of shares outstanding at such time, rounded
to the nearest cent. Expenses, including the fees payable to the Manager and any
account maintenance and/or distribution fees,  are accrued daily. The per  share
net  asset value of the Class  B, Class C, and Class  D shares generally will be
lower than the per share  net asset value of the  Class A shares reflecting  the
daily  expense  accruals of  the  account maintenance,  distribution  and higher
transfer agency fees applicable with respect to  the Class B and Class C  shares
and  the daily expense accruals of  the account maintenance fees applicable with
respect to Class D shares. Moreover the per share net asset value of the Class B
and Class C shares generally will be lower than the per share net asset value of
its Class D  shares reflecting the  daily expense accruals  of the  distribution
fees  and higher transfer agency fees applicable with respect to the Class B and
Class C shares of the  Fund. Even under those  circumstances, the per share  net
asset  value of  the four classes  eventually will tend  to converge immediately
after the payment of dividends, which will differ by approximately the amount of
the expense accrual differentials between the classes.

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

                              SHAREHOLDER SERVICES

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

INVESTMENT ACCOUNT

    Each shareholder whose account  is maintained at the  Transfer Agent has  an
Investment  Account and  will receive statements,  at least  quarterly, from the
Transfer Agent. These  statements will  serve as  transaction confirmations  for
automatic investment purchases and the reinvestment of ordinary income dividends
and  long-term capital  gain distributions.  The statements  will also  show any
other activity in the account  since the preceding statement. Shareholders  will
receive separate transaction confirmations for each purchase or sale transaction
other  than  automatic investment  purchases  and the  reinvestment  of ordinary
income  dividends  and  long-term   capital  gain  distributions.   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

                                       28
<PAGE>
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.

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

AUTOMATIC INVESTMENT PLANS

    A  shareholder may make  additions to an  Investment Account at  any time by
purchasing Class A shares (if an eligible  Class A investor as described in  the
Prospectus)  or Class  B, Class  C or  Class D  shares at  the applicable public
offering price either through  the shareholder's securities  dealer, or by  mail
directly  to the  Transfer Agent, acting  as agent for  such securities 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 the 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. Cash  payments  can also  be  direct
deposited to the shareholder's bank account.

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

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

                                       29
<PAGE>
    At the time of each withdrawal payment, sufficient Class A or Class D shares
are redeemed from those on deposit  in the shareholder's account to provide  the
withdrawal  payment specified  by the  shareholder. The  shareholder may specify
either a dollar amount or a  percentage of the value of  his Class A or Class  D
shares.  Redemptions will be made at net  asset value as determined at the close
of business on the New York Stock Exchange 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
redemptions  will be made at net asset value  on the first Monday of every other
month, and quarterly,  semiannual or annual  redemptions are made  at net  asset
value on the first Monday of months selected at the shareholder's option. If the
first  Monday of the month is a holiday, the redemption will be processed at net
asset value on the next business  day. The Systematic Redemption Program is  not
available  if 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 the Fund have an exchange  privilege
with  certain other  MLAM-advised mutual funds  listed below.  Under the Merrill
Lynch Select  Pricing-SM- System,  Class  A shareholders  may exchange  Class  A
shares  of the Fund for  Class A shares of a  second MLAM-advised mutual fund if
the shareholder holds any Class  A shares of the second  fund in his account  in
which  the exchange is made at the time of the exchange or is otherwise eligible
to purchase Class A shares of the second fund. If the Class A shareholder  wants
to  exchange Class A shares for shares of a second MLAM-advised mutual fund, and
the shareholder does not hold Class A  shares of the second fund in his  account
at  the time of  the exchange and is  not otherwise eligible  to acquire Class A
shares of the second fund,  the shareholder will receive  Class D shares of  the
second  fund as a result  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

                                       30
<PAGE>
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 the Fund
is "tacked" to the holding period of the newly acquired shares of the other Fund
as more fully described below. Class A, Class B, Class C and Class D shares 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 another MLAM-advised  mutual
fund  ("new Class A or Class D shares")  are transacted on the basis of relative
net asset value per Class A or Class D share, respectively, plus an amount equal
to the  difference, if  any, between  the sales  charge previously  paid on  the
outstanding  Class A or Class D shares and  the sales charge payable at the time
of the  exchange  on  the new  Class  A  or  Class D  shares.  With  respect  to
outstanding  Class A or Class D shares as to which previous exchanges have taken
place, the "sales  charge previously paid"  shall include the  aggregate of  the
sales charges paid with respect to such Class A or Class D shares in the initial
purchase  and any subsequent exchange. Class A or Class D shares issued pursuant
to dividend  reinvestment are  sold on  a no-load  basis in  each of  the  funds
offering  Class A  or Class  D shares. For  purposes of  the exchange privilege,
Class A  and Class  D shares  acquired through  dividend reinvestment  shall  be
deemed  to  have  been  sold with  a  sales  charge equal  to  the  sales charge
previously paid on the Class A or Class D shares on which the dividend was paid.
Based on this formula,  Class A and  Class D shares  generally may be  exchanged
into  the Class A  or Class D  shares of the  other funds or  into shares of the
Class A and Class D money market funds with a reduced or without a sales charge.

    In addition, each of the funds with  Class B and Class C shares  outstanding
("outstanding  Class B  or Class C  shares") offers to  exchange its outstanding
Class B or Class C shares for Class B or Class C shares, respectively, of  other
MLAM-advised  mutual funds  ("new Class B  or Class  C shares") on  the basis of
relative net asset value per  Class B or Class C  share, without the payment  of
any  contingent deferred sales load that might otherwise be due on redemption of
the outstanding shares. Class B shareholders of the Fund exercising the exchange
privilege will  continue to  be subject  to  the Fund's  CDSC schedule  if  such
schedule  is higher than the deferred sales  charge schedule relating to the new
Class B shares  acquired through  use of  the exchange  privilege. In  addition,
Class  B shares of the Fund acquired  through use of the exchange privilege will
be subject to the Fund's CDSC schedule if such schedule is higher than the  CDSC
schedule  relating to the Class B shares of the Fund from which the exchange has
been made. For purposes  of computing the  sales load that may  be payable on  a
disposition  of the new  Class B or Class  C shares, the  holding period for the
outstanding Class B or Class C shares  is "tacked" to the holding period of  the
new  Class B or  Class C shares. For  example, an investor  may exchange Class B
shares of the Fund for those of Merrill Lynch Special Value Fund, Inc. ("Special
Value Fund") after  having held the  Fund's Class B  shares for two  and a  half
years.  The 2% sales load  that generally would apply  to a redemption would not
apply to the exchange. Three years later  the investor may decide to redeem  the
Class  B  shares  of  Special  Value  Fund  and  receive  cash.  There  will  be

                                       31
<PAGE>
no CDSC due  on this  redemption, since  by "tacking" the  two and  a half  year
holding period of the Fund's Class B shares to the three year holding period for
the  Special Value Fund Class B shares, the investor will be deemed to have held
the new Class B shares for more than five years.

    Shareholders also may  exchange shares of  the Fund into  shares of a  money
market  fund advised by  the Manager or  its affiliates, but  the period of time
that Class B or Class C  shares are held in a  money market fund will not  count
towards  satisfaction of the holding period requirement for purposes of reducing
the CDSC  or,  with respect  to  Class B  shares,  towards satisfaction  of  the
conversion period. However, shares of a money market fund which were acquired as
a  result of an exchange for Class B or Class C shares of the Fund may, in turn,
be exchanged back  into Class B  or Class  C shares, respectively,  of any  fund
offering  such shares, in which event the holding  period for Class B or Class C
shares of the Fund will be aggregated with previous holding periods for purposes
of reducing the CDSC. Thus, for example, an investor may exchange Class B shares
of the  Fund for  shares  of Merrill  Lynch Institutional  Fund  ("Institutional
Fund")  after having held the Class B shares  for two and a half years and three
years later decide to redeem the shares  of Institutional Fund for each. At  the
time  of this redemption, the 2%  CDSC that would have been  due had the Class B
shares of the Fund been  redeemed for cash rather  than exchanged for shares  of
Institutional  Fund  will  be  payable.  If,  instead  of  such  redemption  the
shareholder exchanged  such  shares for  Class  B shares  of  a fund  which  the
shareholder  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  (the "Code").  If it  so qualifies,  in  any
taxable  year in which it distributes at least 90% of its taxable net income and
90%  of  its  tax-exempt  net  income  (see  below),  the  Fund  (but  not   its
shareholders)  will not be subject  to Federal income tax  to the extent that it
distributes its net investment income and net realized capital gains. The  Trust
intends to cause the Fund to distribute substantially all of such income.

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

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

    The Trust intends to qualify the Fund to pay "exempt-interest dividends"  as
defined in Section 852(b)(5) of the Code. Under such section if, at the close of
each quarter of the Fund's taxable year, at least 50% of the value of the Fund's
total assets consists of obligations exempt from Federal income tax ("tax-exempt
obligations")   under  Section  103(a)  of   the  Code  (relating  generally  to
obligations of a state or local governmental unit), the Fund shall be  qualified
to  pay exempt-interest dividends to  its Class A, Class B,  Class C and Class D
shareholders  (together,  the  "shareholders").  Exempt-interest  dividends  are
dividends  or  any part  thereof  paid by  the  Fund which  are  attributable to
interest  on   tax-exempt   obligations  and   designated   by  the   Trust   as
exempt-interest  dividends in a written notice mailed to the Fund's shareholders
within 60 days after the close of the Fund's taxable year. For this purpose, the
Fund will allocate  interest from  tax-exempt obligations (as  well as  ordinary
income, capital gains and tax preference items, discussed below) among the Class
A,  Class B, Class  C and Class D  shareholders according to  a method (which it
believes is  consistent with  the Commission's  exemptive order  permitting  the
issuance  and sale  of multiple classes  of shares)  that is based  on the gross
income allocable to Class A,  Class B, Class C  and Class D shareholders  during
the  taxable  year or  such other  method  as the  Internal Revenue  Service may
prescribe.  To  the  extent  that  the  dividends  distributed  to  the   Fund's
shareholders  are derived  from interest income  exempt from  Federal income tax
under Code  Section  103(a)  and  are  properly  designated  as  exempt-interest
dividends, they will be excludable from a shareholder's gross income for Federal
income  tax  purposes.  Exempt-interest  dividends  are  included,  however,  in
determining the portion,  if any,  of a  person's social  security benefits  and
railroad  retirement  benefits  subject  to Federal  income  taxes.  Interest on
indebtedness incurred or continued

                                       43
<PAGE>
to purchase or carry shares of  a RIC paying exempt-interest dividends, such  as
the Fund, will not be deductible by the investor for Federal income tax purposes
to  the  extent  attributable  to  exempt-interest  dividends.  Shareholders are
advised to consult their  tax advisers with  respect to whether  exempt-interest
dividends  retain the exclusion under Code Section 103(a) if a shareholder would
be treated as a "substantial user" or "related person" under Code Section 147(a)
with respect to property financed with  the proceeds of an issue of  "industrial
development bonds" or "private activity bonds", if any, held by the Fund.

    The  portion  of the  Fund's  exempt-interest dividends  paid  from interest
received by the Fund from Pennsylvania Municipal Bonds also will be exempt  from
Pennsylvania  personal  income tax.  In the  case  of residents  of the  City of
Philadelphia, distributions  which are  derived  from interest  on  Pennsylvania
Municipal  Bonds or which  are designated as capital  gain dividends for Federal
income tax  purposes  will  be  exempt from  the  Philadelphia  School  District
investment  income  tax. Shares  of the  Fund will  be exempt  from Pennsylvania
county personal property taxes, the City of Pittsburgh personal property tax and
the School District of Pittsburgh personal property tax to the extent the Fund's
portfolio securities  consist  of Pennsylvania  Municipal  Bonds on  the  annual
assessment  date. Shareholders subject  to income taxation  by states other than
Pennsylvania will realize  a lower after  tax rate of  return than  Pennsylvania
shareholders  since the dividends distributed by  the Fund generally will not be
exempt, to any significant  degree, from income taxation  by such other  states.
The  Trust will inform shareholders annually regarding the portion of the Fund's
distributions which constitutes exempt-interest dividends and the portion  which
is  exempt  from Pennsylvania  personal income  taxes.  The Trust  will allocate
amounts exempt from Pennsylvania personal income  taxes among Class A, Class  B,
Class  C and Class  D shareholders based  on a method  similar to that described
above for the  allocation of  exempt-interest dividends for  Federal income  tax
purposes.

    It  is unclear at this time whether an investment in the Fund by a corporate
shareholder will qualify as an exempt asset for purposes of apportionment of the
Pennsylvania  capital  stock/franchise  tax.   To  the  extent   exempt-interest
dividends  are excluded  from taxable  income for  Federal corporate  income tax
purposes  (determined  before   net  operating  loss   carryovers  and   special
deductions),  they will not be subject  to the Pennsylvania corporate net income
tax. An investment in or distributions from investment income and capital  gains
of  the Fund, including exempt-interest dividends, may be subject to state taxes
in states other than Pennsylvania (and, possibly, in Pennsylvania) and to  local
taxes  imposed  by  municipalities  in  states  other  than  Pennsylvania  (and,
possibly, municipalities in Pennsylvania).  Accordingly, investors in the  Fund,
including,  in  particular,  corporate investors  which  may be  subject  to the
Pennsylvania capital stock/franchise tax, should consult their tax advisers with
respect to the application of such taxes as to an investment in the Fund, to the
receipt of Fund dividends and to their Pennsylvania tax situation in general.

    To the extent that the Fund's distributions are derived from interest on its
taxable investments or from an excess  of net short-term capital gains over  net
long-term  capital losses ("ordinary income  dividends"), such distributions are
considered ordinary income  for Federal  and Pennsylvania  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. 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

                                       44
<PAGE>
earnings  and profits  will first  reduce the adjusted  tax basis  of a holder's
shares and, after such  adjusted tax basis is  reduced to zero, will  constitute
capital  gains to such holder (assuming the shares are held as a capital asset).
Any loss upon the sale or exchange of  Fund shares held for six months or  less,
however, will be treated as long-term capital loss to the extent of capital gain
dividends received by the shareholder. In addition, such loss will be disallowed
to  the extent of any exempt-interest  dividends received by the shareholder. If
the Fund pays a dividend in January which was declared in the previous  October,
November  or December to  shareholders of record  on a specified  date in one of
such months, then such dividend will be  treated for tax purposes as being  paid
by the Fund and received by its shareholders on December 31 of the year in which
such dividend was declared.

    The   Code  subjects  interest  received  on  certain  otherwise  tax-exempt
securities to an alternative minimum tax. The alternative minimum tax applies to
interest received  on "private  activity  bonds" issued  after August  7,  1986.
Private  activity  bonds  are bonds  which,  although tax-exempt,  are  used for
purposes other than those  generally performed by  governmental units and  which
benefit  non-governmental entities (e.g., bonds  used for industrial development
or housing purposes). Income received on such bonds is classified as an item  of
"tax  preference",  which  could  subject  investors  in  such  bonds, including
shareholders of the Fund, to an alternative minimum tax. The Fund will  purchase
such  "private activity bonds" and the  Trust will report to shareholders within
60 days after the  Fund's taxable year-end the  portion of 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 of the Fund 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.

                                       45
<PAGE>
    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.

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

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

ENVIRONMENTAL TAX

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

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

                                       46
<PAGE>
    One  of the requirements for qualification as a RIC is that less than 30% of
the Fund's gross income be derived from gains from the sale or other disposition
of securities held  for less  than three months.  Accordingly, the  Fund may  be
restricted  in effecting closing transactions within three months after entering
into an option or financial futures contract.

PENNSYLVANIA TAXATION

    Under present Pennsylvania law,  the Fund, as  presently configured, is  not
subject  to Pennsylvania income  taxes or Pennsylvania  county personal property
taxes.

    The foregoing  is  a  general  and abbreviated  summary  of  the  applicable
provisions  of the Code, Treasury regulations and applicable Pennsylvania income
tax laws presently in effect. For  the complete provisions, reference should  be
made  to  the  pertinent  Code sections,  the  Treasury  regulations promulgated
thereunder and the applicable Pennsylvania tax  laws. The Code and the  Treasury
regulations,  as well as the Pennsylvania income tax laws, are subject to change
by legislative 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 Pennsylvania)  and with  specific questions as  to Federal,  foreign,
state or local taxes.

                                PERFORMANCE DATA

    From  time to time the Fund may  include its average annual total return and
other  total  return  data,  as  well  as  yield  and  tax-equivalent  yield  in
advertisements  or information furnished to present or prospective shareholders.
Total return, yield  and tax-equivalent yield  figures are based  on the  Fund's
historical  performance  and are  not intended  to indicate  future performance.
Average annual total  return 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 the  Class A  and
Class D shares and the CDSC that would be applicable to a complete redemption of
the investment at the end of the specified period in the case of the Class B and
Class C shares.

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

                                       47
<PAGE>
total  return data generally will be lower than average annual total return data
since the average rates of return reflect compounding of return; aggregate total
return data generally will be higher than average annual total return data since
the aggregate rates of return reflect compounding over a longer period of time.

    Set forth below is total return, yield and tax-equivalent yield  information
for  the Class A and Class B shares of the Fund for the periods indicated. Since
Class C and  Class D  shares have  not been  issued prior  to the  date of  this
Statement  of Additional Information, performance information concerning Class C
and Class D shares is not provided.

                              GENERAL INFORMATION

DESCRIPTION OF SHARES

    The Declaration  of Trust  provides that  the Trust  shall be  comprised  of
separate  Series each of which  will consist of a  separate portfolio which will
issue separate shares.  The Trust is  presently comprised of  the Fund,  Merrill
Lynch  Arizona Municipal Bond Fund, Merrill  Lynch Arkansas Municipal Bond Fund,
Merrill Lynch Colorado Municipal Bond Fund, Merrill Lynch Connecticut  Municipal
Bond  Fund, Merrill  Lynch Florida Municipal  Bond Fund,  Merrill Lynch Maryland
Municipal Bond Fund,  Merrill Lynch Massachusetts  Municipal Bond Fund,  Merrill
Lynch Michigan Municipal Bond Fund, Merrill Lynch Minnesota Municipal Bond Fund,
Merrill Lynch New Mexico Municipal Bond Fund, Merrill Lynch New Jersey Municipal
Bond  Fund,  Merrill Lynch  New York  Municipal Bond  Fund, Merrill  Lynch North
Carolina Municipal Bond Fund,  Merrill Lynch Ohio  Municipal Bond Fund,  Merrill
Lynch  Oregon Municipal Bond  Fund and Merrill Lynch  Texas Municipal Bond Fund.
The Trustees are authorized  to create an unlimited  number of Series and,  with
respect  to each  Series, to  issue an unlimited  number of  full and fractional
shares of beneficial interest, par value of $.10 per share, of different classes
and to divide or combine  the shares into a greater  or lesser number of  shares
without  thereby changing the proportionate  beneficial interests in the Series.
Shareholder approval is not necessary for the authorization of additional Series
or classes of a Series of the Trust. At the date of this Statement of Additional
Information, the shares of the Fund are  divided into Class A, Class B, Class  C
and  Class D shares. Class A,  Class B, Class C and  Class D shares represent an
interest in the same assets of the Fund and are identical in all respects except
that the Class B, Class  C and Class D shares  bear certain expenses related  to
the  account maintenance and/or  distribution of such  shares and have exclusive
voting rights  with respect  to  matters relating  to such  account  maintenance
and/or  distribution expenditures. The Trust has received an order (the "Order")
from the Commission  permitting the  issuance and  sale of  multiple classes  of
shares. The Order permits the Trust to issue additional classes of shares of any
Series  if the Board of Trustees deems such  issuance to be in the best interest
of the Trust. The Board of Trustees of the Trust may classify and reclassify the
shares of any Series into additional classes at a future date.

    All shares of the Trust have equal voting rights, except that only shares of
the respective  Series are  entitled to  vote on  matters concerning  only  that
Series  and, as  noted above,  Class B,  Class C  and Class  D shares  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 meetings of
shareholders for the purposes of electing Trustees unless and until such time as
less  than  a majority  of  the Trustees  holding  office have  been  elected by
shareholders,  at  which  time  the  Trustees   then  in  office  will  call   a
shareholders'  meeting  for  the  election  of  Trustees.  Shareholders  may, in
accordance with  the terms  of the  Declaration  of Trust,  cause a  meeting  of
shareholders  to be held for  the purpose of voting  on the removal of Trustees.
Also, the Trust will be  required to call a  special meeting of shareholders  in
accordance  with  the requirements  of  the 1940  Act  to seek  approval  of new
management and advisory  arrangements, of  a material  increase in  distribution
fees,  or of a change in the fundamental policies, objectives or restrictions of
a Series.

    The obligations and liabilities of a particular Series are restricted to the
assets of that Series and  do not extend to the  assets of the Trust  generally.
The   shares   of  each   Series,   when  issued,   will   be  fully   paid  and

                                       49

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

    The Manager provided the initial capital  for the Fund by purchasing  10,000
shares  of the Fund for  $100,000. Such shares were  acquired for investment and
can only be disposed of by  redemption. The organizational expenses of the  Fund
(estimated  at approximately  $81,100) were paid  by the Fund  and are amortized
over a period  not exceeding five  years. The proceeds  realized by the  Manager
upon  the redemption  of any  of the  shares initially  purchased by  it will be
reduced by the proportionate amount of unamortized organizational expenses which
the number of shares redeemed bears to the number of shares initially purchased.
Such organizational  expenses  include  certain of  the  initial  organizational
expenses  of the Trust which have been allocated to the Fund by the Trustees. If
additional Series are added  to the Trust, the  organizational expenses will  be
allocated among the Series in a manner deemed equitable by the Trustees.

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 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  publicly  offered  prior  to  the date  of  this  Statement  of Additional
Information.

                                   APPENDIX I
               ECONOMIC AND FINANCIAL CONDITIONS IN PENNSYLVANIA

    THE INFORMATION SET FORTH BELOW IS DERIVED FROM OFFICIAL STATEMENTS PREPARED
IN  CONNECTION WITH  THE ISSUANCE OF  BONDS OF THE  COMMONWEALTH OF PENNSYLVANIA
(THE  "COMMONWEALTH")  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 COMMONWEALTH OR  OF
LOCAL  GOVERNMENTAL  UNITS  LOCATED  IN  THE  COMMONWEALTH.  THE  FUND  HAS  NOT
INDEPENDENTLY VERIFIED THIS INFORMATION.

    Many  factors  affect  the  financial  condition  of  the  Commonwealth   of
Pennsylvania  (also  referred  to  as  the  "Commonwealth")  and  its  political
subdivisions, such as  social, environmental  and economic  conditions, many  of
which  are not within the control of  such entities. Pennsylvania and certain of
its counties, cities and  school districts and public  bodies have from time  to
time  in  the  past  encountered  financial  difficulties  which  have adversely
affected their  respective  credit  standings. Such  difficulties  could  affect
outstanding  obligations  of such  entities, including  obligations held  by the
Fund. For  example, the  financial condition  of the  City of  Philadelphia  had
impaired  its ability to borrow and  resulted in its obligations generally being
downgraded by the major rating services to below investment grade.

    The  General  Fund,  the  Commonwealth's  largest  fund,  receives  all  tax
revenues,  non-tax revenues  and Federal  grants and  entitlements that  are not
specified by law to be deposited  elsewhere. The majority of the  Commonwealth's
operating  and administrative expenses  are payable from  the General Fund. Debt
service on all bonded indebtedness of  the Commonwealth, except that issued  for
highway  purposes or for the benefit of  other special revenue funds, is payable
from the General Fund.

    For its  fiscal year  ended June  30, 1993,  the Pennsylvania  General  Fund
closed   with  revenues  higher  than  anticipated  and  expenditures  about  as
projected, resulting in an ending unappropriated balance surplus (on a budgetary
basis) of $242.3  million. Cash  revenues were  $41.5 million  above the  budget
estimate and totalled $14.633 billion (representing less than a 1% increase over
revenues  for the 1992 fiscal year). A reduction in the personal income tax rate
in July, 1992 and revenues from retroactive corporate tax increases received  in
fiscal  1992 were  responsible, in  part, for  the low  rate of  revenue growth.
Appropriations (less lapses) totalled an estimated $13.870 billion  representing
a  1.1%  increase  over fiscal  1992  amounts.  The low  growth  in  spending is
reportedly a consequence of a low  rate of revenue growth, significant  one-time
expenses  during fiscal 1992,  increased tax refund  reserves to cushion against
adverse decisions on pending litigations, and  the receipt of Federal funds  for
expenditures previously paid out of Commonwealth funds.

    The  1994  fiscal  year closed  with  revenues of  $15,210.7  million, $38.6
million above the  fiscal year  estimate. Additional revenues  were provided  by
higher  than  anticipated  sales tax  revenues  and  a reduction  in  tax refund
reserves resulting  from  a favorable  decision  in a  pending  tax  litigation.
Personal income tax revenues, however, were below estimate. Expenditures (net of
certain   pooled  financing  expenditures  and  appropriation  lapses)  totalled
$14,934.4  million,  representing  a  7.2  percent  increase  over  fiscal  1993
expenditures.

    The  fiscal 1995 budget provides for $15,652.9 million of appropriations, an
increase of 3.9% over appropriations for  fiscal 1994. The budget also  includes
tax  reductions totaling  an estimated  $166.4 million.  The fiscal  1995 budget
projects $4 million fiscal year-end unappropriated surplus.

    The economy of Pennsylvania  is composed of  many diverse sectors  including
manufacturing,  mining, agriculture,  services and  wholesale and  retail trade.
Certain industries traditionally strong in the Commonwealth, such as coal, steel
and railways,  have  declined  and  account for  a  decreasing  share  of  total
employment.  Non-manufacturing employment  has increased steadily  since 1980 to
its 1992 level of 81.3% of total Commonwealth employment. The unemployment  rate
in Pennsylvania in August, 1994 stood at a seasonally adjusted rate of 6.3%. The
seasonally adjusted national unemployment rate for August, 1994 was 6.1%.

    Recent  economic indicators suggest that the Pennsylvania economy is growing
at a moderate  pace. The  expansion is generally  broad-based across  geographic
regions and industrial sectors, and inflation is not accelerating. Some evidence
suggests,  however, that  the pace  of growth  may slow  somewhat in  the coming
months.

    The current Constitutional provisions pertaining to Commonwealth debt permit
the issuance of the following types  of debt: (i) debt to suppress  insurrection
or rehabilitate areas affected by disaster, (ii) electorate-approved debt, (iii)
debt  for capital projects subject to an  aggregate debt limit of 1.75 times the
annual average tax  revenues of  the preceding five  fiscal years  and (iv)  tax
anticipation  notes payable in the fiscal year  of issuance. All debt except tax
anticipation notes must be amortized in substantial and regular amounts.

    Debt service on all bonded indebtedness of Pennsylvania, except that  issued
for  highway purposes or the benefit of  other special revenue funds, is payable
from Pennsylvania's General Fund, which receives all Commonwealth revenues  that
are  not specified by  law to be deposited  elsewhere. As of  June 30, 1994, the
Commonwealth had $5,075.8 million of general obligation debt outstanding.

    Other  state-related   obligations   include  "moral   obligations".   Moral
obligation indebtedness may be issued by the Pennsylvania Housing Finance Agency
("PHFA"),  a state  agency which  provides financing  for housing  for lower and
moderate income  families, and  The Hospitals  and Higher  Education  Facilities
Authority  of  Philadelphia,  a municipal  authority  organized by  the  City of
Philadelphia to, among other things, acquire  and prepare various sites for  use
as intermediate care facilities for the mentally retarded. PHFA's bonds, but not
its  notes,  are partially  secured by  a  capital reserve  fund required  to be
maintained by PHFA in an amount equal to the maximum annual debt service on  its
outstanding  bonds in  any succeeding  calendar year.  PHFA is  not permitted to
borrow additional funds as long as any deficiency exists in the capital  reserve
fund.

    Certain  state-created agencies  have statutory authorization  to incur debt
for which state appropriations to pay debt service thereon is not required.  The
debt  of these agencies is supported by assets of, or revenues derived from, the
various projects financed and is not an obligation of the Commonwealth. Some  of
these    agencies,   however,   are   indirectly   dependent   on   Pennsylvania
appropriations. In addition, the  Commonwealth maintains pension plans  covering
state  employees, public school employees and employees of certain state-related
organizations. The  total  unfunded  actuarial  accrued  liability  under  these
pension plans for their fiscal years ended in 1994 was $2,456 million.

    The  City of Philadelphia  is the largest  city in the  Commonwealth with an
estimated population  of 1,585,577  according to  the 1990  Census.  Legislation
providing  for the  establishment of  Pennsylvania Intergovernmental Cooperation
Authority ("PICA") to  assist Philadelphia in  remedying fiscal emergencies  was
enacted  by the  Pennsylvania General Assembly  and approved by  the Governor in
June, 1991.  PICA is  designed to  provide assistance  through the  issuance  of
funding debt to liquidate budget deficits and to make

                                       53
<PAGE>
factual  findings and  recommendations to Philadelphia  concerning its budgetary
and  fiscal  affairs.   An  Intergovernmental   Cooperation  Agreement   between
Philadelphia  and PICA  was approved  by City  Council on  January 3,  1992, and
approved by the PICA Board and signed by  the Mayor on January 8, 1992. At  this
time,  Philadelphia is operating under a five  year fiscal plan approved by PICA
on April 6, 1992. Full implementation of  the five year plan was delayed due  to
labor  negotiations which were  not completed until October,  1992. The terms of
the new labor contracts are estimated to cost approximately $144.0 million  more
than what was budgeted in the original five year plan. An amended five-year plan
was  approved  by  PICA in  May,  1993. The  audit  findings show  a  surplus of
approximately $3 million for  the fiscal year ending  June 30, 1993. The  fiscal
1994  budget  projects no  deficit  and a  balanced  budget. The  Mayor's latest
five-year financial plan was approved by PICA on May 2, 1994.

    In June, 1992, PICA issued $474,555,000 of its Special Tax Revenue Bonds  to
provide  financial assistance to  Philadelphia. In July,  1993 and August, 1993,
PICA issued $643,430,000 and $178,675,000, respectively, of Special Tax  Revenue
Bonds  to  refund certain  general  obligation bonds  of  the city  and  to fund
additional capital projects.

    There is various litigation pending  against the Commonwealth, its  officers
and  employees.  An  adverse decision  in  one  or more  of  theses  cases could
materially affect the Commonwealth's governmental operations.

    Currently, Pennsylvania general obligation bonds are rated AA- by Standard &
Poor's and Fitch Investors  Service, Inc., and  A1 by Moody's.  There can be  no
assurance  that the  economic conditions on  which these ratings  are based will
continue or  that particular  bond  issues will  not  be adversely  affected  by
changes in economic or political conditions.

                           RATINGS OF MUNICIPAL BONDS

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

<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 payment or of maintenance of other terms of  the
           contract over any long period of time may be small.
Caa        Bonds  which are rated  Caa are of poor  standing. Such issues may  be in default or
           there may be present elements of danger with respect to principal or interest.
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 nor poorly secured.

DESCRIPTION OF MOODY'S COMMERCIAL PAPER RATINGS

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

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

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

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

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

DESCRIPTION OF STANDARD & POOR'S 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.

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

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

         I.  Likelihood of default -- capacity and willingness of the obligor as
    to the timely payment of interest  and repayment of principal in  accordance
    with the terms of the obligation;

        II. Nature of and provisions of the obligation;

        III. Protection afforded to, and relative position of, the obligation in
    the  event of bankruptcy, reorganization or other arrangement under the laws
    of bankruptcy and other laws affecting creditor's rights.

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

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

DESCRIPTION OF STANDARD & POOR'S CORPORATE BOND RATINGS

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

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

DESCRIPTION OF STANDARD & POOR'S COMMERCIAL PAPER RATINGS

    A Standard & Poor's Commercial Paper  Rating is a current assessment of  the
likelihood of timely payment of debt having an original maturity of no more than
365 days. Ratings are graded into several categories, ranging from "A-1" for the
highest  quality  obligations to  "D" for  the lowest.  These categories  are as
follows:

<TABLE>
<S>        <C>
A-1        This highest category indicates that the degree of safety regarding timely payment
           is  strong.  Those   issues  determined   to  possess   extremely  strong   safety
           characteristics are denoted with a plus sign (+) designation.
A-2        Capacity  for  timely payment  on issues  with  this designation  is satisfactory.
           However, the relative degree  of safety is  not as high  as for issues  designated
           "A-1".
A-3        Issues  carrying this designation have adequate  capacity for timely payment. They
           are, however,  somewhat more  vulnerable  to the  adverse  effects of  changes  in
           circumstances than obligations carrying the higher designations.
B          Issues  rated  "B" are  regarded as  having only  speculative capacity  for timely
           payment.
C          This rating is assigned  to short-term debt obligations  with a doubtful  capacity
           for payment.
D          Debt  rated  "D" is  in  payment default.  The "D"  rating  category is  used when
           interest payments or principal payments are not made on the date due, even if  the
           applicable  grace period has  not expired, unless Standard  & Poor's believes that
           such payments will be made during such grace period.
</TABLE>

    A Commercial Paper  Rating is  not a recommendation  to purchase  or sell  a
security.  The ratings are based on  current information furnished to Standard &
Poor's by the  issuer or obtained  by Standard  & Poor's from  other sources  it
considers  reliable. The  ratings may be  changed, suspended, or  withdrawn as a
result of changes in, or unavailability of, such information.

    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.

                                       58
<PAGE>
    --Amortization schedule (the  larger the  final maturity  relative to  other
      maturities, the more likely it will be treated as a note).

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

    Note rating symbols are as follows:

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

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

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

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

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

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

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

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

        4.   The  issue was privately  placed, in  which case the  rating is not
    published in 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 operative performance  of the issuer and any  guarantor,
as well as the political and economic environment that might affect the issuer's
future financial strength and credit quality.

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

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

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

                                       59
<PAGE>
    Fitch  ratings  are  based  on  information  obtained  from  issuers,  other
obligors,  underwriters, their experts,  and other sources  Fitch believes to be
reliable. Fitch  does  not  audit  or  verify the  truth  or  accuracy  of  such
information.  Ratings may  be changed,  suspended, or  withdrawn as  a result of
changes in, or the unavailability of, information or for other reasons.

<TABLE>
<C>               <S>
             AAA  Bonds considered  to  be  investment  grade and  of  the  highest  credit
                  quality.  The obligor has an exceptionally strong ability to pay interest
                  and repay  principal, which  is  unlikely to  be affected  by  reasonably
                  forseeable events.
              AA  Bonds  considered to  be investment grade  and of very  high quality. The
                  obligor's ability to  pay interest  and repay principal  is very  strong,
                  although not quite as strong as bonds rated "AAA". Because bonds rated in
                  the  "AAA"  and  "AA"  categories  are  not  significantly  vulnerable to
                  foreseeable future  developments, short-term  debt  of these  issuers  is
                  generally rated "F-1+".
               A  Bonds  considered to be investment grade  and of high credit quality. The
                  obligor's ability to pay interest and repay principal is considered to be
                  strong, but  may  be  more  vulnerable to  adverse  changes  in  economic
                  conditions and circumstances than bonds with higher ratings.
             BBB  Bonds  considered  to  be  investment grade  and  of  satisfactory credit
                  quality. The obligor's  ability to  pay interest and  repay principal  is
                  considered  to be  adequate. Adverse  changes in  economic conditions and
                  circumstances, however, are more likely  to have adverse impact on  these
                  bonds,  and  therefore, impair  timely payment.  The likelihood  that the
                  ratings of these bonds  will fall below investment  grade is higher  than
                  for bonds with higher ratings.
</TABLE>

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

    CREDIT  TREND  INDICATOR:  Credit  trend  indicators  show  whether   credit
fundamentals are improving, stable, declining, or uncertain, as follows:

<TABLE>

     Improving    Up-arrow
        Stable    Left-and Right-arrows
     Declining    Down-arrow
     Uncertain    Up-and Down-arrows
</TABLE>

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

<TABLE>
<C>               <S>
             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.

<PAGE>
<TABLE>
<C>               <S>
      WITHDRAWN:  A rating  will  be  withdrawn when  an  issue  matures or  is  called  or
                  refinanced  and, at Fitch's  discretion, when an  issuer fails to furnish
                  proper and timely information.
     FITCHALERT:  Ratings are placed on  FitchAlert to notify  investors of the  occurrence
                  that  is likely to result in a  rating change and the likely direction of
                  such change. These  are designated as  "Positive" indicating a  potential
                  upgrade,  "Negative" for potential downgrade, or "Evolving" where ratings
                  may be raised or lowered. FitchAlert is relatively short-term, and should
                  be resolved within 12 months.
</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 security. The  ratings ("BB" to
"C") represent  Fitch's  assessment  of  the likelihood  of  timely  payment  of
principal  and  interest in  accordance with  the terms  of obligation  for bond
issues not in  default. For defaulted  bonds, the  rating ("DDD" to  "D") is  an
assessment of the ultimate recovery value through reorganization or liquidation.

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

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

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

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

DESCRIPTION OF FITCH INVESTMENT GRADE SHORT-TERM RATINGS

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

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

    Fitch short-term ratings are as follows:

<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 the "F-1+" and "F-1" ratings.
F-3        Fair  Credit  Quality.  Issues assigned  this  rating  have characteristics
           suggesting that the  degree of  assurance for timely  payment is  adequate,
           however, near-term adverse changes could cause these securities to be rated
           below investment grade.
F-S        Weak  Credit  Quality.  Issues assigned  this  rating  have characteristics
           suggesting a  minimal  degree  of  assurance for  timely  payment  and  are
           vulnerable   to  near-term  adverse  changes   in  financial  and  economic
           conditions.
D          Default. Issues  carrying this  rating are  in actual  or imminent  payment
           default.
LOC        The  symbol, LOC, indicates that the rating  is based on a letter of credit
           issued by a commercial bank.

NOTES TO FINANCIAL STATEMENTS



1. Significant Accounting Policies:
Merrill Lynch Pennsylvania Municipal Bond Fund (the "Fund") is part of Merrill
Lynch Multi-State Municipal Series Trust (the "Trust"). The Fund is registered
under the Investment Company Act of 1940 as a non-diversified, open-end
management investment company. The Fund offers 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 a remaining maturity of sixty days or less are valued on an
amortized cost basis, 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 securities or the intended purchase of
securities. Futures contracts are contracts for delayed delivery of securities
at a specific future date and at a specific price or yield. Upon entering into a
contract, the Fund deposits and maintains as collateral such initial margin as
required by the exchange on which the transaction is effected. Pursuant to the
contract, the Fund agrees to receive from or pay to the broker an amount of cash
equal to the daily fluctuation in value of the contract. Such receipts or
payments are known as variation margin and are recorded by the Fund as
unrealized gains or losses. When the contract is closed, the Fund records a
realized gain or loss equal to the difference between the value of the contract
at the time it was opened and the value at the time it was closed.

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

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

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

(f) Dividends and distributions--Dividends from net investment income are
declared daily and paid monthly. Distributions of capital gains are recorded 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 a 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. The Investment
Advisory Agreement obligates FAM to reimburse the Fund to the extent the Fund's
expenses (excluding interest, taxes, distribution fees, brokerage fees and
commissions, and extraordinary items) exceed 2.5% of the Fund's first $30
million of average daily net assets, 2.0% of the next $70 million of average
daily net assets, and 1.5% of the average daily net assets in excess thereof.
FAM's obligation to reimburse the Fund is limited to the amount of the
management fee. No fee payment will be made to the Investment Adviser during any
fiscal year which will cause such expenses to exceed expense limitations at the
time of payment.

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 ongoing account maintenance and distribution fees which are
accrued daily and paid monthly at the annual rate 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") also provides account maintenance and distribution
services to the Fund. As authorized by the Plan, the Distributor has entered
into an agreement with MLPF&S, an affiliate of FAM, 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 $8,083,
and MLPF&S earned dealer concessions of $85,614 on sales of the Fund's Class A
Shares.

MLPF&S also received contingent deferred sales charges of $204,747, relating to
Class B Share transactions during the period.

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, PSI, MLIM, MLFD, FDS, MLPF&S, and/or ML & Co.
