                        SPECIAL MEETING OF STOCKHOLDERS
     OF MERRILL LYNCH MULTI-STATE LIMITED MATURITY MUNICIPAL SERIES TRUST
                                JANUARY 5, 1998
 
  This Joint Proxy Statement and Prospectus (this "Proxy Statement and
Prospectus") is furnished in connection with the solicitation of proxies on
behalf of the Board of Trustees of Merrill Lynch Multi-State Limited Maturity
Municipal Series Trust, a Massachusetts business trust (the "Trust"), for use
at the Special Meeting of Stockholders (the "Meeting") called to approve or
disapprove the proposed reorganization whereby Limited Maturity Portfolio (the
"Limited Maturity Portfolio"), a series of Merrill Lynch Municipal Bond Fund,
Inc., a Maryland corporation (the "Municipal Bond Fund"), will acquire
substantially all of the assets, and will assume substantially all of the
liabilities, of Merrill Lynch Arizona Limited Maturity Municipal Bond Fund
(the "Arizona Fund"), Merrill Lynch Massachusetts Limited Maturity Municipal
Bond Fund (the "Massachusetts Fund"), Merrill Lynch Michigan Limited Maturity
Municipal Bond Fund (the "Michigan Fund"), Merrill Lynch New Jersey Limited
Maturity Municipal Bond Fund (the "New Jersey Fund"), Merrill Lynch New York
Limited Maturity Municipal Bond Fund (the "New York Fund") and Merrill Lynch
Pennsylvania Limited Maturity Municipal Bond Fund (the "Pennsylvania Fund"),
each a series of the Trust (collectively, the "State Funds"), in exchange
solely for an equal aggregate value of newly-issued shares of Common Stock of
Limited Maturity Portfolio (the "Limited Maturity Portfolio Common Stock"),
with a par value of $.10 per share, the subsequent distribution of Limited
Maturity Portfolio Common Stock to the stockholders of the State Funds in
exchange for their shares of beneficial interest of the State Funds, each with
a par value of $.10 per share, and the termination of the State Funds as
series of the Trust (collectively, the "Reorganization").
 
  This Proxy Statement and Prospectus serves as a prospectus of the Municipal
Bond Fund under the Securities Act of 1933, as amended (the "Securities Act"),
in connection with the issuance of Limited Maturity Portfolio Common Stock in
the Reorganization.
 
  Holders of Class A shares of each of the State Funds will be entitled to
receive Class A shares of Limited Maturity Portfolio Common Stock. Holders of
Class B, Class C and Class D shares of each of the State Funds will be
entitled to receive Class D shares of Limited Maturity Portfolio Common Stock.
The aggregate net asset value of Limited Maturity Portfolio Common Stock to be
received by each stockholder of each of the State Funds will equal the
aggregate net asset value of the State Fund shares owned by such stockholder
as set forth in the Agreement and Plan of Reorganization.
 
  Both the Trust and the Municipal Bond Fund are open-end management
investment companies with similar, though not identical, investment
objectives. Specifically, each State Fund seeks to provide stockholders with
as high a level of income exempt from Federal income taxes and personal income
taxes imposed by the designated state (and, in certain instances, state
intangible personal property taxes, corporate income or local personal income
taxes and local personal property taxes) as is consistent with prudent
investment management. Limited Maturity Portfolio seeks to provide
stockholders with as high a level of income exempt from Federal income taxes
as is consistent with prudent investment management. Each State Fund seeks to
achieve its objective by investing primarily in a portfolio of intermediate-
term investment grade obligations of the designated state or its political
subdivisions, agencies or instrumentalities, or certain other jurisdictions,
that pay interest exempt, in the opinion of bond counsel to the issuer, from
Federal income taxes and personal income taxes of the designated state and,
where applicable, state intangible personal property taxes, local personal
property taxes and local personal income taxes in the designated state.
Limited Maturity Portfolio seeks to achieve its objective by investing
primarily in a portfolio of short-term investment grade obligations issued by
or on behalf of states, territories and possessions of the United States and
the District of Columbia and their political subdivisions, agencies and
instrumentalities, the interest on which is exempt from Federal income taxes.
There can be no assurance that, after the Reorganization, Limited Maturity
Portfolio will achieve its investment objective.

1997 (the "Municipal Bond Fund Prospectus") accompanies this Proxy Statement

SUMMARY
 
  The following is a summary of certain information contained elsewhere in
this Proxy Statement and Prospectus and is qualified in its entirety by
reference to the more complete information contained herein and in the
Agreement and Plan of Reorganization, attached hereto as Exhibit I.
 
  In this Proxy Statement and Prospectus, the term "Reorganization" refers
collectively to (i) the acquisition of substantially all of the assets, and
the assumption of substantially all of the liabilities, of each of the State
Funds by Limited Maturity Portfolio of the Municipal Bond Fund and the
subsequent distribution of Limited Maturity Portfolio Common Stock to the
holders of shares of beneficial interest of each of the State Funds and (ii)
the subsequent termination of each of the State Funds as series of the Trust.
 
  At a meeting of the Board of Trustees of the Trust held on September 26,
1997, the Board of Trustees of the Trust approved a proposal that Limited
Maturity Portfolio of the Municipal Bond Fund acquire substantially
 
                                       3
<PAGE>
 
all of the assets, and assume substantially all of the liabilities, of each of
the State Funds in exchange solely for Limited Maturity Portfolio Common Stock
to be distributed to the stockholders of each of the State Funds.
 
  Based upon their evaluation of all relevant information, the Trustees of the
Trust determined that the Reorganization will potentially benefit the holders
of shares of beneficial interest of the State Funds. Specifically, after the
Reorganization, stockholders of each of the State Funds will remain invested
in an open-end fund that has an investment objective and policies similar, but
not identical, to those of the State Funds. In addition, it is anticipated
that stockholders of the State Funds will be subject to a reduced overall
operating expense ratio based on the combined assets of the surviving entity
after the Reorganization. See "The Reorganization--Agreement and Plan of
Reorganization--Potential Benefits to State Fund Stockholders as a Result of
the Reorganization."
 
  In deciding to recommend the Reorganization, the Board of Trustees of the
Trust took into account the investment objective and policies of the State
Funds and of Limited Maturity Portfolio, the expenses incurred both due to the
Reorganization and on an ongoing basis by the new and existing stockholders of
Limited Maturity Portfolio and the potential benefits, including economies of
scale, to the holders of shares of beneficial interest of the State Funds as a
result of the Reorganization. The Trustees also considered the effect of the
Reorganization on the holders of the shares of beneficial interest of Merrill
Lynch California Limited Maturity Municipal Bond Fund and Merrill Lynch
Florida Limited Maturity Municipal Bond Fund, the two series of the Trust that
are not participating in the Reorganization. The Board of Trustees of the
Trust, including all of the Trustees who are not "interested persons," as
defined in the Investment Company Act of 1940, as amended (the "Investment
Company Act"), of the Trust have determined that the Reorganization is in the
best interests of each of the State Funds and of the holders of shares of
beneficial interest of the State Funds and that the interests of such
stockholders will not be diluted as a result of effecting the Reorganization.
 
  If all of the requisite approvals are obtained, it is anticipated that the
Reorganization will occur as soon as practicable after such approval, provided
that the State Funds and Limited Maturity Portfolio have obtained prior to
that time a favorable private letter ruling from the Internal Revenue Service
(the "IRS") concerning the tax consequences of the Reorganization as set forth
in the Agreement and Plan of Reorganization. Under the Agreement and Plan of
Reorganization, however, the Board of Trustees of the Trust or the Board of
Directors of Municipal Bond Fund may cause the Reorganization to be postponed
or abandoned should either Board determine that it is in the best interests of
the stockholders of either the Trust or Municipal Bond Fund, respectively, to
do so. The Agreement and Plan of Reorganization may be terminated, and the
Reorganization abandoned, whether before or after approval by the stockholders
of the State Funds, at any time prior to the Exchange Date (as defined below),
(i) by mutual consent of the Board of Trustees of the Trust and the Board of
Directors of Municipal Bond Fund; (ii) by the Board of Trustees of the Trust
if any condition to the Trust's obligations has not been fulfilled or waived
by such Board; or (iii) by the Board of Directors of Municipal Bond Fund if
any condition to Municipal Bond Fund's obligations has not been fulfilled or
waived by such Board.

                               rates set forth in the table below. These rates
                               are applied to the average daily net assets of
                               each of the three portfolios of Municipal Bond
                               Fund to the extent that the aggregate of the
                               average daily net assets of the three combined
                               portfolios of Municipal Bond Fund exceeds $250
                               million, $400 million, $550 million and $1.5
                               billion, respectively (each such amount being a
                               breakpoint level). The portion of the assets of
                               a portfolio to which the rate at each
                               breakpoint level applies will be determined on
                               a "uniform percentage" basis. The uniform
                               percentage applicable to a breakpoint level is
                               determined by dividing the amount of the
                               aggregate of the average daily net assets of
                               the three combined portfolios of the Municipal
                               Bond Fund that falls within that breakpoint
                               level by the aggregate of the average daily net
                               assets of the three combined portfolios. The
                               amount of the fee for a portfolio at each
                               breakpoint level is determined by multiplying
                               the average daily net assets of that portfolio
                               by the uniform percentage applicable to that
                               breakpoint level and multiplying the product by
                               the advisory fee rate.

                               As of October 31, 1997, the three portfolios of
                               Municipal Bond Fund had aggregate net assets of
                               $3,934,278,239; Limited Maturity Portfolio had
                               net assets of $398,404,439. At this asset level
                               the advisory fee rate of Limited Maturity
                               Portfolio would be 0.33%.
 
                               Class Structure. Like each of the State Funds,
                               Limited Maturity Portfolio offers four classes
                               of shares under the Merrill Lynch Select
                               PricingSM System. The Class A, Class B, Class C
                               and Class D shares issued by Limited Maturity
                               Portfolio are identical in all respects to the
                               Class A, Class B, Class C and Class D shares
                               issued by the State Funds except that they
                               represent ownership interests in a different
                               investment portfolio. See "The Reorganization--

                               Overall Expense Ratio. The overall operating
                               expense ratio for the year ended July 31, 1997
                               for Class A shares was 0.41% for Limited
                               Maturity Portfolio and for each of the State
                               Funds was as set forth below:

                               If the Reorganization had taken place on August
                               1, 1996 (the first day of the year ended July
                               31, 1997), the overall operating expense ratio
                               for Class A shares for the combined entity on a
                               pro forma basis would have been 0.41%.
 
                               The above ratios would differ for Class B,
                               Class C and Class D shares as a result of class
                               specific distribution and account maintenance
                               expenditures. See "The Reorganization--

                               Purchase of Shares. Shares of Limited Maturity
                               Portfolio are offered continuously for sale to
                               the public in substantially the same manner as
                               the shares of each of the State Funds. See "The
                               Reorganization--Comparison of the State Funds

                               Redemption of Shares. The redemption procedures
                               for shares of Limited Maturity Portfolio are
                               the same as the redemption procedures for
                               shares of each of the State Funds. See "The
                               Reorganization--Comparison of the State Funds

                               each State Fund with respect to dividends and
                               distributions are identical to those of

                               Net Asset Value. The State Funds and Limited
                               Maturity Portfolio each determines the net
                               asset value of each class of its shares once
                               daily 15 minutes after the close of business on
                               the New York Stock Exchange (the "NYSE")
                               (generally, 4:00 p.m., New York time), on each
                               day during which the NYSE is open for trading.
                               The State Funds and Limited Maturity Portfolio
                               each compute net asset value per share in the
                               same manner. See "The Reorganization--

TAX CONSIDERATIONS             The State Funds and Limited Maturity Portfolio
                               have jointly requested a private letter ruling
                               from the IRS with respect to the Reorganization
                               to the effect that, among other things, neither
                               the State Funds nor Limited Maturity Portfolio
                               will recognize gain or loss on the transaction
                               and stockholders of the State Funds will not
                               recognize gain or loss on the exchange of their
                               shares of beneficial interest for shares of
                               Limited Maturity Portfolio Common Stock. The
                               consummation of the Reorganization is subject
                               to the receipt of
 
                                      14
<PAGE>
 
                               such ruling. The Reorganization will not affect
                               the status of Limited Maturity Portfolio as a
                               regulated investment company ("RIC") under the
                               Internal Revenue Code of 1986, as amended
                               ("Code"). Each State Fund will liquidate
                               pursuant to the Reorganization and will
                               terminate as a series of the Trust.
 
                               After the Reorganization, the distributions
                               received from Limited Maturity Portfolio will
                               be exempt from Federal income tax but generally
                               will not be exempt to any significant degree
                               from personal income tax at the state level.
                               Currently, the portion of a State Fund's exempt
                               interest dividends paid from interest received
                               by the State Fund from municipal bonds of the
                               designated state is also exempt from personal
                               income tax in the designated state and, where
                               applicable, corporate income or local personal
                               income taxes. Currently, shares of a State Fund
                               may also be exempt from state intangible
                               personal property tax in the designated state.

                    RISK FACTORS AND SPECIAL CONSIDERATIONS
 
  Since the State Funds and Limited Maturity Portfolio invest primarily in a
portfolio of Municipal Bonds, any risks inherent in such investments are
equally applicable to the State Funds and Limited Maturity Portfolio and will
be similarly pertinent to the combined fund after the Reorganization. It is
expected that the Reorganization itself will not adversely affect the rights
of holders of shares of beneficial interest of the State Funds or shares of
Limited Maturity Portfolio Common Stock or create additional risks.
 
PORTFOLIO MANAGEMENT
 
  Each State Fund ordinarily will invest at least 65% (80% in the case of the
New Jersey Fund) of its total assets in its respective State Municipal Bonds
and, therefore, is more susceptible to factors adversely affecting issuers of
Municipal Bonds in such state than is a tax-exempt mutual fund that is not
concentrated in issuers of a particular state's Municipal Bonds to this
degree, such as Limited Maturity Portfolio. Limited Maturity Portfolio
currently contemplates that it will not invest more than 25% of its total
assets (taken at market value) in Municipal Bonds of issuers that are located
in the same state. Certain special considerations and risk factors specific to
each State Fund are described in the Limited Maturity Trust Prospectus. FAM
does not believe that the current economic conditions described in the Limited
Maturity Trust Prospectus will have a significant adverse effect on the
ability of any State Fund to invest in investment grade State Municipal Bonds.
 
MATURITY
 
  Limited Maturity Portfolio may not invest in Municipal Bonds with a
remaining term exceeding four years. The State Funds invest primarily in
Municipal Bonds with remaining maturities of between one and ten years.
Because the State Funds hold Municipal Bonds with maturities which exceed the
permitted maturity for investments by Limited Maturity Portfolio, prior to the
Reorganization, the State Funds will dispose of all portfolio securities that
have maturities greater than four years. FAM believes that such disposition
will not affect the receipt of a favorable private letter ruling from the IRS
with respect to the tax-free status of the Reorganization.
 
TAX CONSIDERATIONS
   
  The distributions to stockholders of Limited Maturity Portfolio are, and
after the Reorganization will be, exempt from Federal income tax but not, to
any significant degree, from personal income tax at the state level. The
distributions to stockholders of the State Funds, however, are currently
exempt from Federal income taxes and personal income taxes imposed by the
designated state (and, in certain instances, corporate income or local
personal income taxes) and may also provide exemption of State Fund shares
from state intangible personal property taxes. See "Comparison of the State
Funds and Limited Maturity Portfolio--Taxation of Limited Maturity Portfolio,
State Funds and Their Stockholders" and "Agreement and Plan of
Reorganization--Tax Consequences of the Reorganization."     
 
  Stockholders should consult their tax advisers regarding the effect of the
Reorganization on their investment.

INVESTMENT OBJECTIVE AND POLICIES
 
  The structure, organization and investment policies of the State Funds and
Limited Maturity Portfolio are similar, but not identical. The State Funds and
Limited Maturity Portfolio are sometimes referred to herein collectively as
the "Funds" and individually as a "Fund." Certain of the significant
differences are discussed below.
 
  The investment objective of each State Fund is to provide stockholders with
as high a level of income exempt from Federal income taxes, the designated
state's personal income taxes and, where applicable, state
 
                                      25
<PAGE>
 
intangible personal property tax, and corporate income or local personal
income taxes as is consistent with prudent investment management. The
investment objective of Limited Maturity Portfolio is to provide stockholders
with as high a level of income exempt from Federal income taxes as is
consistent with its investment policies and prudent investment management.
There can be no assurance that after the Reorganization, Limited Maturity
Portfolio will achieve its investment objective.
 
  Each State Fund seeks to achieve its objective by providing investors with
the opportunity to invest in a portfolio of securities consisting primarily of
intermediate-term investment grade obligations issued by or on behalf of the
designated state or its political subdivisions, agencies or instrumentalities,
and obligations of other qualifying issuers, such as issuers located in Puerto
Rico, the U.S. Virgin Islands and Guam. Limited Maturity Portfolio seeks to
achieve its objective by investing in a diversified portfolio consisting
primarily of short-term investment grade obligations issued by or on behalf of
states, territories and possessions of the United States and the District of
Columbia and their political subdivisions, agencies and instrumentalities, the
interest from which is exempt from Federal income taxes (such obligations are
herein referred to as "Municipal Bonds"). The investment objective of each of
the State Funds and of Limited Maturity Portfolio is a fundamental policy that
may not be changed without a vote of a majority of that Fund's outstanding
voting securities. At times, the State Funds and Limited Maturity Portfolio
may seek to hedge their portfolios through the use of futures contracts and
options transactions thereon to reduce volatility in the net asset value of
their shares.
 
  Each State Fund will maintain at all times, except during temporary
defensive periods, at least 65% of its total assets invested in its respective
State Municipal Bonds/1/; the New Jersey Fund will maintain at least 80% of
its total assets invested in New Jersey State Municipal Bonds.
 
  Limited Maturity Portfolio invests in a portfolio consisting primarily of
short-term investment grade Municipal Bonds. Municipal Bonds in Limited
Maturity Portfolio will be either Municipal Bonds with remaining maturities of
less than four years or short-term municipal notes, which typically are issued
with a maturity of not more than one year. Municipal notes include tax
anticipation notes, bond anticipation notes and revenue anticipation notes.
Interest rates on short-term Municipal Bonds may fluctuate more widely from
time to time than interest rates on long-term Municipal Bonds. However,
because of the shorter maturities, the market value of the Municipal Bonds
held by Limited Maturity Portfolio can be expected to fluctuate less as a
result of changes in interest rates.
 
  Each State Fund will invest primarily in Municipal Bonds with remaining
maturities of between one and ten years, and may not invest in Municipal Bonds
with remaining maturities of greater than ten years. For cash management and
temporary defensive purposes, each State Fund may invest in Municipal Bonds
with remaining maturities of less than one year. It is anticipated that,
depending on market conditions, the dollar weighted average maturity of each
State Fund's portfolio will not exceed five years. For purposes of these
investment policies, a bond will be treated as having a maturity earlier than
its stated maturity date if such bond has technical features which, in the
judgment of FAM, will result in the bond being valued in the market as though
it has such earlier maturity. Interest rates on shorter-term Municipal Bonds
may fluctuate more widely from time to time than interest rates on longer-term
Municipal Bonds. However, because of their limited maturities, the market
value of the Municipal Bonds held by each State Fund can be expected to
fluctuate less as a result of changes in interest rates.
 
  The investment grade Municipal Bonds in which the State Funds and Limited
Maturity Portfolio invest are those Municipal Bonds rated at the date of
purchase within the four highest ratings as determined by either Moody's
Investors Service, Inc. ("Moody's") (currently "Aaa", "Aa", "A" and "Baa"),
Standard & Poor's Ratings Services ("S&P") (currently AAA, AA, A and BBB) or
Fitch Investors Service, Inc. ("Fitch") (currently AAA, AA, A and BBB) or, if
unrated, are considered to be of comparable quality by FAM. See Exhibit II--
"Ratings of Municipal Bonds."
- --------
/1/ State Municipal Bonds are obligations that pay interest exempt from
    Federal income taxes, state personal income taxes in the designated state
    and, where applicable, corporate income or local personal income taxes
    and/or state intangible personal property taxes.
 
                                      26
<PAGE>
 
  Limited Maturity Portfolio may invest in variable rate demand notes
("VRDNs") which are tax-exempt obligations containing a floating or variable
interest rate adjustment formula and an unconditional right of demand to
receive payment of the unpaid principal balance plus accrued interest upon a
short notice period not to exceed seven days. The interest rates are
adjustable at intervals ranging from daily to up to six months based on some
prevailing market rate for similar investments, such adjustment formula being
calculated to maintain the market value of the VRDN at approximately the par
value of the VRDN upon the adjustment date. The adjustments are typically
based upon the prime rate of a bank or some other appropriate interest rate
adjustment index.
 
  Limited Maturity Portfolio may also invest in VRDNs in the form of
participation interests ("Participating VRDNs") in variable rate tax-exempt
obligations held by a financial institution, typically a commercial bank
("institution"). Participating VRDNs provide Limited Maturity Portfolio with a
specified undivided interest (up to 100%) in the underlying obligation and the
right to demand payment of the unpaid principal balance plus accrued interest
on the Participating VRDNs from the institution upon a specified number of
days' notice, not to exceed seven days. In addition, the Participating VRDN is
backed by an irrevocable letter of credit or guaranty of the institution.
Limited Maturity Portfolio has an undivided interest in the underlying
obligation and thus participates on the same basis as the institution in such
obligation except that the institution typically retains fees out of the
interest paid on the obligation for servicing the obligation, providing the
letter of credit and issuing the repurchase commitment.
 
  Limited Maturity Portfolio has been advised by its counsel that the interest
received on Participating VRDNs will be treated as interest from tax-exempt
obligations as long as Limited Maturity Portfolio does not invest more than a
limited amount (not more than 20%) of its total assets in such investments and
certain other conditions are met. It is contemplated that Limited Maturity
Portfolio will not invest more than a limited amount of its total assets in
Participating VRDNs. The State Funds may also invest in VRDNs and
Participating VRDNs. See the Municipal Bond Fund Prospectus for information
about investment in such securities.
 
  Each State 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 S&P 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, a State Fund will rely on FAM's
judgment, analysis and experience in evaluating the creditworthiness of the
issuer of such securities. FAM 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 Objectives and Policies" in the
Limited Maturity Trust Statement for a more detailed discussion of the
pertinent risk factors involved in investing in "high yield" or "junk" bonds
and Exhibit II--"Ratings of Municipal Bonds" for additional information
regarding ratings of debt securities. None of the State Funds intends to
purchase debt securities that are in default or which FAM believes will be in
default.
 
  On a temporary basis, each Fund may invest in short-term tax-exempt or
taxable securities (Limited Maturity Portfolio may only invest in taxable
securities), short-term U.S. Government securities, repurchase agreements or
cash. Such securities or cash will not exceed 20% of each Fund's net assets
except during interim periods pending investment of the net proceeds from
public offerings of the Fund's securities and temporary defensive periods
when, in the opinion of FAM, prevailing market or economic conditions warrant.
 
  Each State Fund is classified as non-diversified within the meaning of the
Investment Company Act, which means that it is not limited by such Act in the
proportion of its total assets that it may invest in securities of a single
issuer. However, each State Fund's investments are limited so as to qualify
the State Fund for the special tax treatment afforded RICs under the Code. See
"The Reorganization--Agreement and Plan of Reorganization--Tax Consequences of
the Reorganization." To qualify, among other requirements, each State Fund
limits its
 
                                      27
<PAGE>
 
investments so that, at the close of each quarter of the taxable year, (i) not
more than 25% of the market value of the State Fund's total assets are
invested in the securities (other than U.S. Government 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 are invested in the
securities (other than U.S. Government securities) of a single issuer. Limited
Maturity Portfolio is classified as diversified. A fund which elects to be
classified as "diversified" under the Investment Company Act must satisfy the
foregoing 5% requirement with respect to 75% of its total assets. To the
extent that a State Fund assumes large positions in the securities of a small
number of issuers, that Fund's yield may fluctuate to a greater extent than
that of a diversified fund as a result of changes in the financial condition
or in the market's assessment of the issuers.
 
DESCRIPTION OF MUNICIPAL BONDS
 
  Municipal Bonds include debt obligations issued to obtain funds for various
public purposes, including construction of a wide range of public facilities,
refunding of outstanding obligations and obtaining funds for general operating
expenses and loans to other public institutions and facilities. In addition,
certain types of industrial development bonds are issued by or on behalf of
public authorities to finance various privately operated facilities, including
pollution control facilities. For purposes of this Proxy Statement and
Prospectus, such obligations are Municipal Bonds if the interest paid thereon
is exempt from Federal income tax, even though such bonds may be "private
activity bonds" as discussed below.
 
  The two principal classifications of Municipal Bonds are "general
obligation" bonds and "revenue" or "special obligation" bonds. General
obligation bonds are secured by the issuer's pledge of faith, credit and
taxing power for the payment of principal and interest. Revenue or special
obligation bonds are payable only from the revenues derived from a particular
facility or class of facilities or, in some cases, from the proceeds from a
special excise tax or other specific revenue source such as from the user of
the facility being financed. Industrial development bonds are in most cases
revenue bonds and generally do not constitute the pledge of the credit or
taxing power of the issuer of such bonds. The payment of the principal and
interest on such industrial development 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. Municipal Bonds also may include "moral
obligation" bonds, which normally are issued by special purpose public
authorities. If an issuer of moral obligation bonds is unable to meet its
obligations, the repayment of such bonds becomes a moral commitment but not a
legal obligation of the state or municipality in question.
 
  Each Fund may purchase Municipal Bonds classified as "private activity
bonds" (in general, bonds that benefit non-governmental entities). Interest
received on certain tax-exempt securities that are classified as "private
activity bonds" may subject certain investors in a Fund to an alternative
minimum tax. There is no limitation on the percentage of each Fund's assets
that may be invested in Municipal Bonds that may subject certain investors to
an alternative minimum tax. See the discussion under "Taxes" in the Municipal
Bond Fund Prospectus and the Limited Maturity Trust Prospectus.
 
  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 that may be enacted in the future may affect
the availability of Municipal Bonds for investment by the Funds.
 
OTHER INVESTMENT POLICIES
 
  The State Funds and Limited Maturity Portfolio have each adopted certain
other policies as set forth below:
 
  Borrowings. Notwithstanding a less restrictive fundamental policy permitting
borrowings of up to 33 1/3% of total assets, as a matter of operating policy,
the Municipal Bond Fund does not intend to have Limited Maturity Portfolio (or
any other portfolio) borrow amounts in excess of 10% of the total assets of
Limited Maturity Portfolio, taken at market value, and then only from banks as
a temporary measure for extraordinary or emergency purposes such as the
redemption of shares of Limited Maturity Portfolio. No State Fund may borrow
 
                                      28
<PAGE>
 
amounts in excess of 20% of its total assets, taken at market value (excluding
the amount borrowed), and then only from banks as a temporary measure for
extraordinary or emergency purposes such as to meet redemption requests.
Neither the State Funds nor Limited Maturity Portfolio will purchase
securities while borrowings are outstanding.
 
  When-Issued Securities and Delayed Delivery Transactions. The State Funds
and Limited Maturity Portfolio may purchase or sell Municipal Bonds on a
delayed delivery basis or on a when-issued basis at fixed purchase or sale
terms. These transactions arise when securities are purchased or sold with
payment and delivery taking place in the future. The value of the obligation
on the delivery date may be more or less than its purchase price. A separate
account will be established with the respective Fund's custodian consisting of
cash, cash equivalents or liquid securities having a market value at all times
at least equal to the amount of the commitment.
 
  Indexed and Inverse Floating Obligations. The State Funds and Limited
Maturity Portfolio may utilize indexed and inverse floating obligations in
connection with their investment strategies. See the Municipal Bond Fund
Prospectus and Limited Maturity Trust Prospectus for a detailed discussion of
these policies. Limited Maturity Portfolio may not invest in such illiquid
obligations if such investments, together with other illiquid investments,
would exceed 10% of its total assets; for each of the State Funds, this
limitation is 15%.
 
  Call Rights. Each State Fund may purchase, either directly from the issuer
or from a third party, a Municipal Bond issuer's contractual right to call all
or a portion of such Municipal Bond for mandatory tender for purchase (a "Call
Right"). A State Fund purchasing a Call Right may or may not own the related
Municipal Bond. A holder of a Call Right may exercise such right to require a
mandatory tender for the purchase of the related Municipal Bonds, subject to
certain conditions. A Call Right that is not exercised prior to the maturity
of the related Municipal Bond will expire without value. The economic effect
of holding both the Call Right and the related Municipal Bond is identical to
holding a Municipal Bond as a non-callable security. A State Fund may not
invest in such illiquid obligations if such investments, together with other
illiquid investments, would exceed 15% of that Fund's total assets.
 
  Forward Commitments. Limited Maturity Portfolio may purchase Municipal Bonds
on a forward commitment basis at fixed purchase terms. The purchase will be
recorded on the date Limited Maturity Portfolio enters into the commitment and
the value of the security will hereafter be reflected in the calculation of
Limited Maturity Portfolio's net asset value. The value of the security on the
delivery date may be more or less than its purchase price. A separate account
of Limited Maturity Portfolio will be established with its custodian
consisting of cash or liquid Municipal Bonds having a market value at all
times at least equal to the amount of the forward commitment.
 
INFORMATION REGARDING OPTIONS AND FUTURES TRANSACTIONS
 
  Financial Futures Contracts and Options Thereon. The State Funds and Limited
Maturity Portfolio are authorized to purchase and sell certain financial
futures contracts ("financial futures contracts") and options thereon.
Financial futures contracts and options thereon are used solely for the
purposes of hedging a Fund's investments in Municipal Bonds against declines
in value and hedging against increases in the cost of securities it intends to
purchase. A financial futures contract obligates the seller of a contract to
deliver and the purchaser of a contract to take delivery of the type of
financial instrument covered by the contract or, in the case of index-based
financial futures contracts, to make and accept a cash settlement, at a
specific future time for a specified price. A sale of financial futures
contracts or options thereon 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 or options. A purchase of financial futures contracts or
options thereon 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
financial futures contracts or options.
 
  The purchase or sale of a financial futures contract or option thereon
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
 
                                      29
<PAGE>
 
the broker effecting the transaction equal to approximately 5% of the contract
amount must be deposited with the broker. This amount is known as initial
margin. Subsequent payments to and from the broker, called variation margin,
are made on a daily basis as the price of the financial futures contract or
option thereon fluctuates making the long and short positions in the financial
futures contract or option thereon more or less valuable.
 
  Each Fund may purchase and sell financial futures contracts based on The
Bond Buyer Municipal Bond Index, a price-weighted measure of the market value
of 40 large tax-exempt issues, and purchase and sell put and call options on
such financial futures contracts for the purpose of hedging Municipal Bonds
that the Fund holds or anticipates purchasing against adverse changes in
interest rates.
 
  Each State Fund also may purchase and sell financial futures contracts on
U.S. Government securities and write and purchase put and call options on such
financial futures contracts as a hedge against adverse changes in interest
rates as described more fully in the Limited Maturity Trust Statement. With
respect to U.S. Government securities, currently there are financial futures
contracts based on long-term U.S. Treasury bonds, U.S. Treasury notes, GNMA
Certificates and three-month U.S. Treasury bills.
 
  Subject to policies adopted by the Trustees of the Trust, the State Funds
also may enter into other financial futures transactions, such as financial
futures contracts or options on other municipal bond indices which may become
available, if FAM and the Trustees of the Trust should determine that there is
normally a sufficient correlation between the prices of such financial futures
contracts or options thereon and the Municipal Bonds in which a Fund invests
to make such hedging appropriate.
 
  Risk Factors in Financial Futures Contracts and Options Thereon. Utilization
of financial futures contracts and options thereon involves the risk of
imperfect correlation in movements in the price of financial futures contracts
and options thereon and movements in the price of the security that is the
subject of the hedge. If the price of the financial futures contract or option
thereon moves more or less than the price of the security that is the subject
of the hedge, a Fund will experience a gain or loss that will not be
completely offset by movements in the price of such security. There is a risk
of imperfect correlation where the securities underlying financial futures
contracts or options thereon have different maturities, ratings, geographic
compositions or other characteristics than the security being hedged. In
addition, the correlation may be affected by additions to or deletions from
the index that serves as a basis for a financial futures contract or option
thereon. Finally, in the case of financial futures contracts on U.S.
Government securities and options on such financial futures contracts, the
anticipated correlation of price movements between the U.S. Government
securities underlying the financial futures contracts or options and Municipal
Bonds may be adversely affected by economic, political, legislative or other
developments that have a disparate impact on the respective markets for such
securities.
 
  Under regulations of the Commodity Futures Trading Commission, the futures
trading activities described herein will not result in a Fund's being deemed a
"commodity pool," as defined under such regulations, provided that the Fund
adheres to certain restrictions. In particular, the Fund may purchase and sell
futures contracts and options thereon (i) for bona fide hedging purposes, and
(ii) for non-hedging purposes, if the aggregate initial margin and premiums
required to establish positions in such contracts and options does not exceed
5% of the liquidation value of the Fund's portfolio, after taking into account
unrealized profits and unrealized losses on any such contracts and options.
Margin deposits may consist of cash or securities acceptable to the broker and
the relevant contract market.
 
  When a Fund purchases a financial futures contract, or writes a put option
or purchases a call option thereon, it will maintain an amount of cash, cash
equivalents (e.g., commercial paper and daily tender adjustable notes) or
other liquid securities in a segregated account with the Fund's custodian, so
that the amount so segregated plus the amount of initial and variation margin
held in the account of its broker equals the market value of the financial
futures contract, thereby ensuring that the use of such financial futures
contract is unleveraged.
 
  Although certain risks are involved in financial futures contracts and
options thereon, FAM believes that, because each Fund will engage in
transactions involving financial futures contracts and options thereon only
for
 
                                      30
<PAGE>
 
hedging purposes, the options and futures portfolio strategies of a Fund will
not subject the Fund to certain risks frequently associated with speculation
in financial futures contracts and options thereon. A Fund may be restricted
in engaging in transactions involving financial futures contracts and options
thereon due to the Federal tax requirement that less than 30% of its gross
income in each taxable year be derived from the sale or other disposition of
securities held for less than three months. Under recently enacted
legislation, this requirement will no longer apply to Limited Maturity
Portfolio after its fiscal year ending June 30, 1998 or to the State Funds
after their fiscal years ending July 31, 1998.
 
  The volume of trading in the exchange markets with respect to Municipal Bond
options may be limited, and it is impossible to predict the amount of trading
interest that may exist in such options. In addition, there can be no
assurance that viable exchange markets will continue to be available.
 
  Each Fund intends to enter into financial futures contracts and options
thereon, on an exchange or in the over-the-counter market, only if there
appears to be a liquid secondary market for such financial futures contracts
or options. There can be no assurance, however, that a liquid secondary market
will exist at any specific time. Thus, it may not be possible to close a
financial futures contract position or the related option. The inability to
close financial futures contract positions or the related options also could
have an adverse impact on a Fund's ability to hedge effectively its portfolio.
There is also the risk of loss by a Fund of margin deposits or collateral in
the event of bankruptcy of a broker with which the Fund has an open position
in a financial futures contract or the related option.
 
  The liquidity of a secondary market in a financial futures contract or
option thereon may be adversely affected by "daily price fluctuation limits"
established by commodity exchanges which limit the amount of fluctuation in a
financial 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 in the past have reached or exceeded the daily limit on a
number of consecutive trading days.
 
  The successful use of financial futures contracts and options thereon also
depends on the ability of FAM to forecast correctly the direction and extent
of interest rate movements within a given time frame. To the extent these
rates remain stable during the period in which a financial futures contract or
related option is held by a Fund or moves in a direction opposite to that
anticipated, the Fund may realize a loss on the hedging transaction that is
not fully or partially offset by an increase in the value of portfolio
securities. As a result, a Fund's total return for such period may be less
than if it had not engaged in the hedging transaction. Furthermore, each State
Fund only will engage in hedging transactions from time to time and may not
necessarily be engaging in hedging transactions when movements in interest
rates occur.
 
INVESTMENT RESTRICTIONS
 
  Other than as noted above under "The Reorganization--Comparison of the State
Funds and Limited Maturity Portfolio--Investment Objectives and Policies" and
"--Other Investment Policies," each of the State Funds and Limited Maturity
Portfolio have identical investment restrictions. See "Investment
Restrictions" in the Municipal Bond Fund Statement and "Investment
Restrictions" in the Limited Maturity Trust Statement.

PORTFOLIO TRANSACTIONS
 
  The procedures for engaging in portfolio transactions are the same for each
State Fund and Limited Maturity Portfolio. Subject to policies established by
the Board of Trustees of the Trust and the Board of Directors of Municipal
Bond Fund. FAM is primarily responsible for the execution of the portfolio
transactions for the State Funds and Limited Maturity Portfolio. In executing
such transactions, FAM seeks to obtain the best results for each entity,
taking into account such factors as price (including the applicable brokerage
commission or dealer spread), size of order, difficulty of execution and
operational facilities of the firm involved and the firm's risk in positioning
a block of securities. While FAM generally seeks reasonably competitive
commission rates, the State Funds and Limited Maturity Portfolio do not
necessarily pay the lowest commission or spread available.
 
  Neither any State Fund nor Limited Maturity Portfolio has any obligation to
deal with any broker or dealer in the execution of transactions in portfolio
securities. Subject to obtaining the best price and execution, securities
firms that provide supplemental investment research to FAM, including Merrill
Lynch, Pierce, Fenner & Smith Incorporated ("Merrill Lynch"), may receive
orders for transactions by a Fund. Information so received will be in addition
to, and not in lieu of, the services required to be performed by FAM under its
investment advisory agreements with the Trust and the Municipal Bond Fund, and
the expenses of FAM will not necessarily be reduced as a result of the receipt
of such supplemental information.
 
  The securities in which each State Fund and Limited Maturity Portfolio
primarily invest are traded in the over-the-counter markets, and the State
Funds and Limited Maturity Portfolio normally deal directly with the dealers
who make markets in the securities involved, except in those circumstances
where better prices and execution are available elsewhere. Under the
Investment Company Act, except as permitted by exemptive order, persons
affiliated with a State Fund or Limited Maturity Portfolio are prohibited from
dealing with that fund as principals in the purchase and sale of securities.
Since transactions in the over-the-counter markets usually involve
transactions with dealers acting as principals for their own account, a State
Fund or Limited Maturity Portfolio will not deal with affiliated persons,
including Merrill Lynch and its affiliates, in connection with such
transactions, except that pursuant to an exemptive order obtained by FAM, a
State Fund or Limited Maturity Portfolio may engage in principal transactions
with Merrill Lynch in high quality, short-term, tax-exempt securities. In
addition, the Funds may not purchase securities, including Municipal Bonds,
during the existence of an underwriting syndicate of which Merrill Lynch is a
member or in a private placement in which Merrill Lynch serves as placement
agent except pursuant to procedures approved by the Board that either comply
with rules adopted by the Commission or interpretations of the Commission
staff. An affiliated person of a State Fund or Limited Maturity Portfolio may
serve as its broker in over-the-counter transactions conducted on an agency
basis.
 
  The Board of Trustees of the Trust and the Board of Directors of the
Municipal Bond Fund have considered the possibility of recapturing for the
benefit of the Trust or the Municipal Bond Fund brokerage commissions, dealer
spreads and other expenses of possible portfolio transactions, such as
underwriting commissions, by conducting portfolio transactions through
affiliated entities, including Merrill Lynch. For example, brokerage
commissions received by Merrill Lynch could be offset against the investment
advisory fees paid by the State Funds or Limited Maturity Portfolio to FAM.
After considering all factors deemed relevant, the respective Trustees and
Directors made a determination not to seek such recapture. The Boards will
reconsider this matter from time to time.
 
PORTFOLIO TURNOVER
 
  Generally, neither the State Funds nor Limited Maturity Portfolio purchases
securities for short-term trading profits. However, any State Fund or Limited
Maturity Portfolio may dispose of securities without regard to the time that
they have been held when such action, for defensive or other reasons, appears
advisable to FAM. However, the Funds monitor their trading so as to comply
with the Federal tax requirement that less than 30% of gross income be derived
from the sale or other disposition of securities held for less than three
months. Under recently enacted legislation, this requirement will no longer
apply to Limited Maturity Portfolio after its fiscal year ending June 30, 1998
or to the State Funds after their fiscal years ending July 31, 1998. As a
result of the
 
                                      34
<PAGE>
 
investment policies of the State Funds and of Limited Maturity Portfolio,
their portfolio turnover rates may be higher than that of other investment
companies; however, it is extremely difficult to predict portfolio turnover
rates with any degree of accuracy. (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 a 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 rate of
Limited Maturity Portfolio for the fiscal years ended June 30, 1997 and 1996
was 61.90% and 88.32%, respectively. For the fiscal years ended July 31, 1997
and 1996, the portfolio turnover rates for each of the State Funds were as
follows:

ADDITIONAL INFORMATION
 
  Net Asset Value. The net asset value per share for each of the State Funds
and for Limited Maturity Portfolio is determined as of 15 minutes after the
close of business on the NYSE (generally, 4:00 p.m., New York time) on each
day during which the NYSE is open for trading. For purposes of determining the
net asset value of a share of beneficial interest of the State Funds or a
share of Common Stock of Limited Maturity Portfolio, the value of the
securities held plus any cash or other assets (including interest and
dividends accrued but not yet received) minus all liabilities (including
accrued expenses) is divided by the total number of shares outstanding at such
time rounded to the nearest cent. Expenses, including the fees payable to FAM,
and any account maintenance and/or distribution fees are accrued daily.
 
  Stockholder Services. Limited Maturity Portfolio offers a number of
stockholder services and investment plans designed to facilitate investment in
its shares. In addition, U.S. stockholders of each class of shares of Limited
Maturity Portfolio have an exchange privilege with certain other MLAM-advised
mutual funds. Stockholder services, including exchange privileges, available
to stockholders of the State Funds and Limited Maturity Portfolio are
substantially the same. For a description of these services, see "Stockholder
Services" in the Municipal Bond Fund Prospectus.
 
  Custodian. The Bank of New York, 90 Washington Street, 12th Floor, New York,
New York 10286, acts as custodian of the cash and securities of the State
Funds and Limited Maturity Portfolio.
 
  Transfer Agent, Dividend Disbursing Agent and Registrar. Merrill Lynch
Financial Data Services, Inc., 4800 Deer Lake Drive East, Jacksonville,
Florida 32246-6484, serves as the transfer agent, dividend disbursing agent
and registrar with respect to each State Fund and Limited Maturity Portfolio
(the "Transfer Agent"), at the same rate, pursuant to separate registrar,
transfer agency and service agreements with the Trust on behalf of each of the
State Funds and with the Municipal Bond Fund on behalf of Limited Maturity
Portfolio.
 
  Capital Stock. The Board of Trustees of the Trust is 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 $0.10
par value of different classes. Each of the State Funds constitutes a series
of the Trust. The shares of each series are divided into four classes
designated Class A, Class B, Class C and Class D shares.

MANAGEMENT
 
  Directors. The Board of Directors of the Municipal Bond Fund currently
consists of six persons, five of whom are not "interested persons," as defined
in the Investment Company Act. The Directors are responsible for the overall
supervision of the operations of the Municipal Bond Fund and perform the
various duties imposed on the directors of investment companies by the
Investment Company Act and under applicable Maryland law. Arthur Zeikel is a
Director of Municipal Bond Fund and a Trustee of the Trust. There is otherwise
no overlap between the Boards.
 
  The Directors of the Municipal Bond Fund are:
 
  ARTHUR ZEIKEL*--President of FAM and its affiliate, MLAM; President and
Director of Princeton Services, Inc. ("Princeton Services"); and Executive
Vice President of Merrill Lynch & Co., Inc. ("ML & Co.").
 
  RONALD W. FORBES--Professor of Finance, School of Business, State University
of New York at Albany.
 
  CYNTHIA A. MONTGOMERY--Professor of Competition and Strategy, Harvard
Business School.
 
  CHARLES C. REILLY--Self-employed financial consultant; former President and
Chief Investment Officer of Verus Capital, Inc.; former Senior Vice President
of Arnhold and S. Bleichroeder, Inc.
 
  KEVIN A. RYAN--Professor of Education, Boston University; Founder and
current Director of The Boston University Center for Advancement of Ethics and
Character.
 
  RICHARD R. WEST--Dean Emeritus, New York University Leonard N. Stern School
of Business Administration.

* Interested person, as defined in the Investment Company Act, of the
  Municipal Bond Fund.
 
  Management and Advisory Arrangements. Pursuant to separate management
agreements between the Trust and FAM on behalf of each State Fund, each State
Fund pays FAM a monthly fee at the annual rate of 0.35% of the average daily
net assets of that State Fund. The Municipal Bond Fund's investment advisory
agreement with FAM provides that as compensation for FAM's services to Limited
Maturity Portfolio, FAM receives at the end of each month a fee determined
based on the annual rates set forth in the table below. These fee rates are
applied to the average daily net assets of each of the three portfolios of the
Municipal Bond Fund to the extent that the aggregate of the average daily net
assets of the three combined portfolios of the Municipal Bond Fund exceeds
$250 million, $400 million, $550 million and $1.5 billion, respectively (each
such amount being a breakpoint level). The portion of the assets of a
portfolio to which the rate at each breakpoint level applies will be
 
                                      36
<PAGE>
 
determined on a "uniform percentage" basis. The uniform percentage applicable
to a breakpoint level is determined by dividing the amount of the aggregate of
the average daily net assets of the three combined portfolios of the Municipal
Bond Fund that falls within that breakpoint level by the aggregate of the
average daily net assets of the three combined portfolios. The amount of the
fee for a portfolio at each breakpoint level is determined by multiplying the
average daily net assets of that portfolio by the uniform percentage
applicable to that breakpoint level and multiplying that product by the
advisory fee rate.

  At July 31, 1997, the average daily net assets of the three portfolios of
Municipal Bond Fund aggregated approximately $3.9 billion. At that date, the
average daily net assets of Limited Maturity Portfolio were $415.5 million and
the advisory fee rate of Limited Maturity Portfolio was 0.33%. For the fiscal
year ended June 30, 1997, FAM received $1,552,369 from Limited Maturity
Portfolio in advisory fees.
 
  As of October 31, 1997, the three portfolios of Municipal Bond Fund had
aggregate net assets of $3,934,278,239; Limited Maturity Portfolio had net
assets of $398,404,439. At this asset level, the advisory fee rate of Limited
Maturity Portfolio would be 0.33%.
 
PURCHASE OF SHARES
 
  The class structure and purchase and distribution procedures for shares of
the State Funds is substantially the same as those of Limited Maturity
Portfolio. For a complete discussion of the four classes of shares and the
purchase and distribution procedures related thereto, see "Merrill Lynch
Select Pricing SM System" and "Purchase of Shares" in either the Municipal
Bond Fund Prospectus or the Limited Maturity Trust Prospectus.
 
REDEMPTION OF SHARES
 
  The procedure for redeeming shares of Limited Maturity Portfolio is
substantially the same as the procedure for redeeming shares of the State
Funds. For purposes of computing any CDSC that may be payable upon disposition
of Limited Maturity Portfolio Common Stock acquired by State Fund stockholders
in the Reorganization, the holding period of State Fund shares outstanding on
the date the Reorganization takes place will be tacked onto the holding period
of Limited Maturity Portfolio Common Stock acquired in the Reorganization.
Only Class A and Class D shares of Limited Maturity Portfolio Common Stock
will be issued in the Reorganization. Class A and Class D shares are not
subject to a CDSC except that certain purchases of $1,000,000 or more which
are not subject to an initial sales charge may instead be subject to a CDSC of
0.20% of amounts redeemed within the first year after purchase. Such CDSC may
be waived in connection with certain fee-based programs and will be waived
with respect to Class A or Class D shares of Limited Maturity Portfolio Common
Stock issued in the Reorganization.
 
VOTING RIGHTS
 
  Stockholders of Limited Maturity Portfolio are entitled to one vote for each
share held and fractional votes for fractional shares held and will vote on
the election of Directors and any other matter submitted to a stockholder
vote. The Municipal Bond Fund does not intend to hold meetings of stockholders
in any year in which the Investment Company Act does not require stockholders
to act upon any of the following matters: (i) election of Directors; (ii)
approval of an investment advisory agreement; (iii) approval of distribution
arrangements; and (iv) ratification of selection of independent accountants.
Voting rights for Directors are not cumulative. Limited Maturity Portfolio
Common Stock to be issued to the State Funds in the Reorganization and
thereafter distributed to the State Fund stockholders will be fully paid and
non-assessable, will have no
 
                                      37
<PAGE>
 
preemptive rights, and will have the conversion rights described in this
Prospectus and Proxy Statement and in the Municipal Bond Fund Prospectus. Each
share of Limited Maturity Portfolio Common Stock is entitled to participate
equally in dividends and distributions declared with respect to Limited
Maturity Portfolio and in the net assets of Limited Maturity Portfolio on
liquidation or dissolution after satisfaction of outstanding liabilities,
except that Class B, Class C and Class D shares bear certain additional
expenses. Rights attributable to shares of the State Funds are substantially
the same as those described above.
 
STOCKHOLDER INQUIRIES
 
  Stockholder inquiries with respect to the State Funds and Limited Maturity
Portfolio may be addressed by telephone at (609) 282-2800 or at the address
set forth on the cover page of this Proxy Statement and Prospectus.
 
DIVIDENDS AND DISTRIBUTIONS
 
  The Trust's current policy with respect to dividends and distributions is
substantially the same as Municipal Bond Fund's policy. It is the intention of
the State Funds and of Limited Maturity Portfolio to distribute all of their
net investment income, if any. In addition, each of the State Funds and
Limited Maturity Portfolio declares and distributes all net realized capital
gains, if any, to stockholders at least annually. Capital gains distributions
will be automatically reinvested in shares unless the stockholder elects to
receive such distributions in cash.
 
  See "Automatic Dividend Reinvestment Plan" below for information as to
electing either dividend reinvestment or cash payments. Any portions of
dividends and distributions which are taxable to stockholders are subject to
income tax whether they are reinvested in shares of such fund or received in
cash.
 
TAXATION OF LIMITED MATURITY PORTFOLIO, STATE FUNDS AND THEIR STOCKHOLDERS
 
  The tax consequences associated with investment in shares of Limited
Maturity Portfolio Common Stock are substantially similar to the tax
consequences associated with investment in shares of the State Funds. Limited
Maturity Portfolio and the State Funds have elected and qualified for the
special tax treatment afforded RICs under the Code. Consequently, the Funds
(but not their stockholders) are not subject to Federal income tax on the part
of their net ordinary income and net realized capital gains which they
distribute to their Class A, Class B, Class C and Class D stockholders
(together, the "Stockholders"). The Funds have distributed substantially all
of such income in taxable years prior to the Reorganization and Limited
Maturity Portfolio intends to distribute substantially all of such income in
taxable years following the Reorganization.
 
  Each Fund has qualified, and Limited Maturity Portfolio intends to continue
to qualify, 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 a Fund's
taxable year, at least 50% of the value of its total assets consists of
obligations exempt from Federal income tax ("tax-exempt obligations") under
Section 103 of the Code (relating generally to obligations of a state or local
governmental unit), the Fund is qualified to pay exempt-interest dividends to
its Stockholders. Exempt-interest dividends are dividends or any part thereof
paid by a Fund which are attributable to interest on tax-exempt obligations
and designated as exempt-interest dividends in a written notice mailed to
Stockholders within 60 days after the close of its taxable year. To the extent
that the dividends distributed to a Fund's Stockholders 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 Stockholder's gross income for Federal income tax purposes. Exempt-
interest dividends are included, however, in determining the portion, if any,
of a person's social security benefits and railroad retirement benefits
subject to Federal income taxes. Interest on indebtedness incurred or
continued to purchase or carry shares of a RIC paying exempt-interest
dividends such as the Limited Maturity Portfolio, will not be deductible by
the investor for purposes of Federal income taxes or state personal income
taxes, where applicable, to the extent attributable to exempt-interest
dividends. Stockholders are advised to consult their tax advisers with respect
to whether exempt-interest dividends retain the exclusion under Code Section
103(a) if a Stockholder 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 Limited Maturity Portfolio.
 
                                      38
<PAGE>
 
  For investors in each of the State Funds, the portion of a Fund's exempt-
interest dividends paid from interest received by the Fund from the municipal
bonds of the designated state is also exempt from personal income tax in the
designated state and, where applicable, corporate income or local personal
income taxes. Currently, shares of a State Fund may also be exempt from state
intangible personal property tax in the designated state. Stockholders subject
to income taxation by states other than the designated state realize a lower
after tax rate of return than Stockholders resident in the designated state
since the dividends distributed by the particular State Fund generally are not
exempt, to any significant degree, from income taxation by such other states.
Stockholders of the State Funds should be aware that after the Reorganization,
the distributions they receive from Limited Maturity Portfolio will be exempt
from Federal income tax but generally will not be exempt to any significant
degree from personal income tax at the state level.
 
  To the extent that a Fund's distributions are derived from interest on
taxable securities 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 state income tax purposes.
Distributions, if any, from an excess of net long-term capital gains over net
short-term capital losses derived from the sale of securities or from certain
transactions in futures or options ("capital gain dividends") are taxable as
long-term capital gains for Federal income tax purposes, regardless of the
length of time a Stockholder has owned Fund shares, and for state income tax
purposes, generally are treated as capital gains which are taxed at ordinary
income tax rates. Recent legislation creates additional categories of capital
gains taxable at different rates. Not later than 60 days after the close of
its taxable year, each Fund will provide its shareholders with a written
notice designating the amounts of any exempt-interest dividends, ordinary
income dividends or capital gain dividends, as well as the amount of capital
gain dividends in the different categories of capital gain referred to above.
Distributions by a Fund, whether from exempt-interest income, ordinary income
or capital gains, are not eligible for the dividends received deduction
allowed to corporations under the Code.
 
  The Code subjects interest received on certain otherwise tax-exempt
securities to an alternative minimum tax. The alternative minimum tax applies
to interest received on "private activity bonds" issued after August 7, 1986.
Private activity bonds are bonds which, although tax-exempt, are used for
purposes other than those generally performed by governmental units and which
benefit non-governmental entities (e.g., bonds used for industrial development
or housing purposes). Income received on such bonds is classified as an item
of "tax preference," which could subject certain investors in such bonds,
including Stockholders of Limited Maturity Portfolio, to an alternative
minimum tax. The Funds report to Stockholders 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 a Fund will be included in
adjusted current earnings, a corporate stockholder may be required to pay
alternative minimum tax on exempt-interest dividends paid by a Fund.
 
  Under certain provisions of the Code, some Stockholders may be subject to a
31% withholding tax on certain ordinary income dividends and on capital gain
dividends and redemption payments ("backup withholding"). Generally,
Stockholders subject to backup withholding will be those for whom no taxpayer
identification number is on file with a Fund or who, to the Fund'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 Stockholder is not otherwise subject to backup withholding.
 
  Ordinary income dividends paid to Stockholders who are nonresident aliens or
foreign entities are subject to a 30% United States withholding tax under
existing provisions of the Code applicable to foreign individuals and entities
unless a reduced rate of withholding or a withholding exemption is provided
under applicable treaty law.
 
  A loss realized on a sale or exchange of shares of a Fund is disallowed if
other Fund shares are acquired (whether under the Automatic Dividend
Reinvestment Plan or otherwise) within a 61-day period beginning 30
 
                                      39
<PAGE>
 
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.
 
  The Code provides that every Stockholder 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 Funds) during the taxable
year.
 
STATE OF ORGANIZATION
 
  The Trust is a Massachusetts business trust and is governed by its
Declaration of Trust, By-laws and applicable Massachusetts law. The Municipal
Bond Fund is a Maryland corporation and is governed by its Articles of
Incorporation, By-laws and Maryland corporation law. Certain differences
between the two forms of organization are summarized below. Stockholders of
the State Funds entitled to vote at the Meeting may obtain a copy of the
Trust's Declaration of Trust and By-laws or Municipal Bond Fund's Articles of
Incorporation and By-laws, without charge, on written request to the Trust or
Municipal Bond Fund, as the case may be.
 
  Shares of Capital Stock. The Declaration of Trust permits the Trustees to
issue an unlimited number of shares and to divide such shares into an
unlimited number of series or classes, all without stockholder approval. The
Trust currently has eight series (including the State Funds) each of which is
divided into four classes. The authorized capital stock of the Municipal Bond
Fund consists of 3,850,000,000 shares of Common Stock, divided into three
series (of which the Limited Maturity Portfolio is one), each of which is
divided into four classes. The Directors of the Municipal Bond Fund may,
without stockholder approval, increase the number of shares authorized and may
classify and reclassify the shares of the Municipal Bond Fund into additional
series or classes at a future date.
 
  Voting Requirements. The By-laws of the Municipal Bond Fund and the Maryland
General Corporation Law (the "Maryland Code") provide that a special meeting
of stockholders must be called upon the written request of stockholders
representing 25% of the votes entitled to be cast at the meeting. The
Declaration of Trust provides that special meetings of stockholders must be
called upon the written request of holders of at least 10% of the outstanding
shares of any series of the Trust.
 
  No amendments may be made to the Declaration of Trust, other than amendments
necessary to conform the Declaration to certain laws or regulations, to change
the name of the Trust, or to make certain non-material changes, without the
affirmative vote of the holders of not less than a majority of the Trust's
outstanding shares or of the affected series or class, as applicable. Under
the Articles of Incorporation of the Municipal Bond Fund and the Maryland
Code, the Articles of Incorporation of the Municipal Bond Fund may be amended
upon adoption of a resolution to that effect by the Directors of the Municipal
Bond Fund and approval of such resolution by the holders of a majority of the
outstanding shares of the Municipal Bond Fund.
 
  Stockholder Meetings. Like the Trust, the Municipal Bond Fund will not be
required to hold annual meetings of its stockholders. The initial Board of
Trustees of the Trust and the initial Board of Directors of the Municipal Bond
Fund were elected by the sole stockholder of the Trust and the Municipal Bond
Fund, respectively, at the time of its organization and have served and will
continue to serve as Trustees or Directors until they resign, die or are
removed. The Trustees of the Trust may be removed for cause by a written
instrument signed by at least two-thirds of the remaining Trustees or by vote
of stockholders of the Trust holding not less than two-thirds of the shares
then outstanding, cast in person or by proxy at any meeting called for the
purpose. The By-laws of the Municipal Bond Fund permit removal of a Director
by the holders of a majority of the outstanding shares of the Municipal Bond
Fund.
 
  Stockholder Liability. Under Massachusetts law, stockholders of the Trust
may, under certain circumstances, be held personally liable as partners for
the Trust's obligations. However, the risk of a stockholder incurring
financial loss on account of stockholder liability is limited to circumstances
in which both inadequate insurance existed and the Trust itself was unable to
meet its obligations. As a Maryland corporation, the stockholders of the
Municipal Bond Fund have no personal liability to the Municipal Bond Fund or
its creditors
 
                                      40
<PAGE>
 
with respect to their stock, except that a stockholder may be liable to the
extent that (1) the subscription price or other agreed consideration for the
stock has not been paid; or (2) liability is imposed under any other provision
of Maryland law.
 
  Liability of Directors and Trustees. Maryland law provides that in addition
to any other liabilities imposed by law, a Director may be liable to the
Municipal Bond Fund for voting or assenting to the declaration of any dividend
or other distribution of assets to Municipal Bond Fund stockholders that is
contrary to Maryland law if it is established that the Director did not act in
good faith, in a manner he or she reasonably believed to be in the best
interest of the Municipal Bond Fund, and with the care that an ordinarily
prudent person in a like position would use under similar circumstances. In
the event of any litigation against the Directors or officers of the Municipal
Bond Fund, Maryland law permits, and the Municipal Bond Fund's By-laws
require, the Municipal Bond Fund to indemnify a Director or officer for
certain expenses and to advance money for such expenses only if he or she
demonstrates that he or she acted in good faith and reasonably believed that
his or her conduct was in, or not opposed to, the best interest of the
Municipal Bond Fund and, with respect to a criminal proceeding, he or she had
no reasonable cause to believe such conduct was unlawful. Under the
Declaration of Trust, the Trustees would be personally liable only for willful
misfeasance, bad faith, gross negligence or reckless disregard of their
duties. Under the Declaration of Trust, Trustees, officers, agents and
employees will be indemnified against all liabilities and expenses (including
amounts paid in satisfaction of judgments, in compromise, as fines and
penalties, and as counsel fees) reasonably incurred by them in connection with
the defense or disposition of any action, suit or other proceeding, whether
civil or criminal, in which they may be involved or with which they may be
threatened, while in office or thereafter, by reason of their being or having
been such a Trustee, officer, employee or agent, except with respect to any
matter as to which they have been adjudicated to have acted in bad faith or
with willful misfeasance, gross negligence or reckless disregard of their
duties, provided, however, that as to any matter disposed of by a compromise
payment, pursuant to a consent decree or otherwise, no indemnification either
for that payment or for any other expenses may be provided unless the Trust
has received a written opinion from independent legal counsel approved by the
Trustees to the effect that if either the matter of willful misfeasance, gross
negligence or reckless disregard of duty, or the matter of good faith and
reasonable belief as to the best interests of the Trust, had been adjudicated,
it would have been adjudicated in favor of the person seeking indemnification.
The Trustees may make advance payments in connection with indemnification,
provided that the indemnified person has given a written undertaking to
reimburse the Trust in the event it is subsequently determined that he or she
is not entitled to such indemnification.
 
  The foregoing is only a summary of certain of the differences between the
Municipal Bond Fund's Articles of Incorporation and By-laws and Maryland law
and the Trust's Declaration of Trust and By-laws and Massachusetts law. It is
not a complete list of differences. Stockholders should refer to the
provisions of such Articles of Incorporation, By-laws, Maryland law, and the
Declaration of Trust, By-laws and Massachusetts law directly for a more
thorough comparison.
 
                     AGREEMENT AND PLAN OF REORGANIZATION
 
GENERAL
 
  Under the Agreement and Plan of Reorganization (attached hereto as Exhibit
I), Limited Maturity Portfolio will acquire substantially all of the assets,
and will assume substantially all of the liabilities, of the State Funds, in
exchange solely for an equal aggregate value of Limited Maturity Portfolio
Common Stock. Upon receipt by the Trust of such shares of Common Stock, the
Trust will distribute the shares to the stockholders of the State Funds in
exchange for their shares of beneficial interest of the State Funds, as
described below.
 
  Generally, the assets transferred by each State Fund to Limited Maturity
Portfolio will equal all investments of such State Fund held in its portfolio
as of the Valuation Time (as defined in the Agreement and Plan of
Reorganization) and all other assets of such State Fund as of such time,
except for any cash or cash equivalents reserved by such State Fund to
discharge its unpaid or contingent liabilities existing at the Valuation Time.
Any unexpended portion of the foregoing funds retained by each State Fund will
be disbursed by such State Fund pro
 
                                      41
<PAGE>
 
rata to its stockholders of record as of the date of the Reorganization upon
consummation of the Reorganization as a final liquidating dividend.
 
  The Trust will distribute Limited Maturity Portfolio Common Stock received
by it pro rata to the stockholders of each State Fund in exchange for such
stockholders' proportional interests in such State Fund. Stockholders of each
State Fund who hold Class A shares as of the Valuation Time will receive Class
A shares of Limited Maturity Portfolio Common Stock and stockholders of each
State Fund who hold Class B, Class C or Class D shares as of the Valuation
Time will receive Class D shares of Limited Maturity Portfolio Common Stock;
such shares of Limited Maturity Portfolio Common Stock will have the same
aggregate net asset value as each such stockholder's interest in such State
Fund as of the Valuation Time. (See "Terms of the Agreement and Plan of
Reorganization--Valuation of Assets and Liabilities" below in this section for
information concerning the calculation of net asset value.) The distribution
will be accomplished by opening new accounts on the books of Limited Maturity
Portfolio in the names of all stockholders of each State Fund, including
stockholders holding such State Fund shares in certificate form, and
transferring to each stockholder's account Limited Maturity Portfolio Common
Stock representing such stockholder's interest previously credited to the
account of such State Fund. Stockholders holding State Fund shares in
certificate form may receive certificates representing Limited Maturity
Portfolio Common Stock credited to their account in respect of such State Fund
shares by sending the certificates to the Transfer Agent accompanied by a
written request for such exchange.
 
  Since Limited Maturity Portfolio Common Stock would be issued at net asset
value in exchange for the net assets of each State Fund having a value equal
to the aggregate net asset value of those shares of such State Fund, the net
asset value per share of Limited Maturity Portfolio should remain virtually
unchanged solely as a result of the Reorganization. Thus, the Reorganization
should result in virtually no dilution of net asset value of Limited Maturity
Portfolio immediately following consummation of the Reorganization. However,
as a result of the Reorganization, a stockholder of each State Fund likely
would hold a reduced percentage of ownership in Limited Maturity Portfolio
than he or she did in such State Fund prior to the Reorganization.
 
PROCEDURE
 
  On September 26, 1997, the Board of Trustees of the Trust, including all of
the Trustees who are not "interested persons," as defined in the Investment
Company Act, of the Trust, approved the Agreement and Plan of Reorganization
and the submission of such Agreement and Plan of Reorganization to the State
Funds' stockholders for approval. The Board of Directors of the Municipal Bond
Fund, including all of the Directors present at the meeting who are not
"interested persons," approved the Agreement and Plan of Reorganization on
September 18, 1997.
 
  If the stockholders of each State Fund approve the Reorganization at the
Meeting and certain conditions are met or waived, the Reorganization will take
place as early as possible in calendar year 1998.
 
  THE BOARD OF TRUSTEES OF THE TRUST RECOMMENDS THAT THE STOCKHOLDERS OF THE
STATE FUNDS APPROVE THE AGREEMENT AND PLAN OF REORGANIZATION.
 
TERMS OF THE AGREEMENT AND PLAN OF REORGANIZATION
 
  The following is a summary of the significant terms of the Agreement and
Plan of Reorganization. This summary is qualified in its entirety by reference
to the Agreement and Plan of Reorganization, attached hereto as Exhibit I.
 
  Valuation of Assets and Liabilities. The respective assets of the State
Funds and Limited Maturity Portfolio will be valued as of the Valuation Time.
The assets in each State Fund and in Limited Maturity Portfolio will be valued
according to the procedures set forth under "Additional Information--
Determination of Net Asset Value" in the Municipal Bond Fund Prospectus.
Purchase orders for any State Fund shares that have not been confirmed as of
the Valuation Time will be treated as assets of such State Fund for purposes
of the Reorganization; redemption requests that have not settled as of the
Valuation Time will be treated as liabilities for purposes of the
Reorganization.
 
                                      42
<PAGE>
 
  Distribution of Limited Maturity Portfolio Common Stock. On the next full
business day following the Valuation Time (the "Exchange Date"), the Municipal
Bond Fund will issue to the Trust a number of shares of Limited Maturity
Portfolio Common Stock the aggregate net asset value of which will equal the
aggregate net asset value of shares of each of the State Funds as of the
Valuation Time. Each holder of shares of beneficial interest of each State
Fund will receive, in exchange for his or her proportionate interest in such
State Fund, Limited Maturity Portfolio Common Stock having the same aggregate
net asset value as the shares of such State Fund held by such stockholder as
of the Valuation Time. Holders of Class A shares of the State Funds will
receive Class A shares of Limited Maturity Portfolio Common Stock; holders of
Class B, Class C or Class D shares of the State Funds will receive Class D
shares of Limited Maturity Portfolio Common Stock.
 
  Expenses. The Agreement and Plan of Reorganization provides for the
allocation of the expenses of the Reorganization between the State Funds and
the Limited Maturity Portfolio. FAM has informed the Funds that it intends to
pay all expenses relating to the Reorganization.
 
  Required Approvals. Under the Trust's Declaration of Trust (as amended to
date) and relevant Massachusetts law, stockholder approval of the Agreement
and Plan of Reorganization requires the affirmative vote of stockholders of
each State Fund voting separately and representing a majority of the
outstanding shares of each State Fund entitled to be voted thereon.
 
  Amendments and Conditions. The Agreement and Plan of Reorganization may be
amended at any time prior to the Exchange Date with respect to any of the
terms therein. The obligations of the Trust and Municipal Bond Fund pursuant
to the Agreement and Plan of Reorganization are subject to various conditions,
including a registration statement on Form N-14 being declared effective by
the Commission, approval of the Reorganization by the stockholders of the
State Funds, a favorable IRS ruling being received as to tax matters, an
opinion of counsel as to securities matters being received and the continuing
accuracy of various representations and warranties of the Trust and Municipal
Bond Fund being confirmed by the respective parties.
 
  Postponement, Termination. Under the Agreement and Plan of Reorganization,
the Board of Trustees of the Trust and the Board of Directors of the Municipal
Bond Fund, respectively, may cause the Reorganization to be postponed or
abandoned should either Board determine that it is in the best interests of
the stockholders of any State Fund or Limited Maturity Portfolio,
respectively, to do so. The Agreement and Plan of Reorganization may be
terminated, and the Reorganization abandoned, at any time, whether before or
after adoption thereof by the stockholders of the State Funds, prior to the
Exchange Date, or the Exchange Date may be postponed: (i) by mutual consent of
the Board of Trustees of the Trust and the Board of Directors of the Municipal
Bond Fund; (ii) the Board of Trustees of the Trust if any condition to the
Trust's obligations has not been fulfilled or waived by such Board; or (iii)
by the Board of Directors of the Municipal Bond Fund if any condition to the
Municipal Bond Fund's obligations has not been fulfilled or waived by such
Board.
 
POTENTIAL BENEFITS TO STOCKHOLDERS OF THE STATE FUNDS AS A RESULT OF THE
REORGANIZATION
 
  The Board of Trustees of the Trust has identified certain potential benefits
to stockholders of the State Funds that are likely to result from the
Reorganization. First, following the Reorganization, State Fund stockholders
will remain invested in an open-end fund that has an investment objective
similar to that of the State Funds, although not identical. In addition, State
Fund stockholders are likely to experience certain additional benefits,
including lower expenses per share, economies of scale and greater flexibility
in portfolio management.
 
  Specifically, after the Reorganization, on a pro forma combined basis,
Limited Maturity Portfolio would pay an advisory fee to FAM at a lower annual
rate than that currently due from the State Funds. If the aggregate assets of
the three portfolios decreases, however, the advisory fee rate of the Limited
Maturity Portfolio could increase to a level that is higher than the advisory
fee rate currently applicable to the State Funds. Also, the total operating
expenses of Limited Maturity Portfolio after the Reorganization, as a
percentage of net assets, would be less than the current operating expenses
for each of the State Funds. However, since inception, FAM has voluntarily
waived the advisory fees payable by each of the State Funds and has reimbursed
each State Fund for
 
                                      43
<PAGE>
 
a portion of its expenses (excluding 12b-1 plan fees). There can be no
assurance that FAM will not discontinue or modify this waiver of fees or
reimbursement of expenses at any time. In addition, certain fixed costs, such
as costs of printing stockholder reports and proxy statements, legal expenses,
audit fees, registration fees, mailing costs and other expenses, would be
spread across a larger asset base, thereby lowering the expense ratio borne by
stockholders of the State Funds. To illustrate the potential economies of
scale, the table below shows, for the year ended July 31, 1997, the total
operating expense ratio for the Class A shares of each of the State Funds, of
Limited Maturity Portfolio and of Limited Maturity Portfolio on a pro forma
basis as if the Reorganization had taken place on August 1, 1996 (the first
day of the year ended July 31, 1997).

(a) FAM has in the past voluntarily waived all of the advisory fees due from
    each of the State Funds and voluntarily reimbursed each State Fund for a
    portion of its other expenses (excluding Rule 12b-1 plan fees). The Total
    Operating Expense Ratio does not give effect to any such waiver or
    reimbursement because FAM may discontinue or reduce such waiver of fees
    and/or assumption of expenses at any time without notice. The actual Total
    Operating Expense Ratio for the year ended July 31, 1997, net of the
    waiver of fees and/or assumption of expenses, would be:

  The preceding table illustrates that (i) the net assets of each of the State
Funds (other than the New York Fund which experienced an increase in 1996 over
1995) and of Limited Maturity Portfolio have generally been decreasing over
the past several years and (ii) in all cases (other than the New York Fund),
average net assets for the most recent fiscal year, are below the net asset
levels achieved for the 1995 fiscal year. FAM anticipates that if this
decrease in net assets were to continue, the State Funds and Limited Maturity
Portfolio might experience increasingly higher operating expense ratios.
Conversely, FAM anticipates that the State Funds and Limited Maturity
Portfolio as a combined entity might experience certain economies of scale,
which might in turn result in a reduction in the entity's overall operating
expense ratio. The State Funds alone might experience the opposite result,
that is, a higher operating expense ratio due to continuing reductions in
already relatively small asset bases. Although there can be no assurance that
the foregoing would in fact occur, FAM believes that the economies of scale
that may be realized as a result of the Reorganization would be beneficial to
stockholders of each of the State Funds.
 
  The Board of Trustees of the Trust also considered the difference in the
risks associated with certain of the investment strategies used by Limited
Maturity Portfolio that are not used by the State Funds.
 
  Based on the foregoing, the Board concluded that the Reorganization presents
no significant risks or costs (including legal, accounting and administrative
costs) that would outweigh the benefits discussed above. In approving the
Reorganization, the Board of Trustees of the Trust determined that the
interests of existing stockholders of the State Funds would not be diluted as
a result of the Reorganization.
 
TAX CONSEQUENCES OF THE REORGANIZATION
 
  General. The Reorganization has been structured with the intention that it
qualify for Federal income tax purposes as a tax-free reorganization under
Section 368(a)(1)(C) of the Code. The State Funds and Limited Maturity
Portfolio have elected and qualified for the special tax treatment afforded
"regulated investment companies" under the Code, and the Limited Maturity
Portfolio intends to continue to so qualify after the Reorganization. The
State Funds and Limited Maturity Portfolio have jointly requested a private
letter ruling from the IRS to the effect that for Federal income tax purposes:
(i) the Reorganization, as described, will constitute a reorganization within
the meaning of Section 368(a)(1)(C) of the Code, and each State Fund and
Limited Maturity Portfolio will be deemed a "party" to the Reorganization
within the meaning of Section 368(b) of the Code; (ii) in accordance with
Section 361(a) of the Code, no gain or loss will be recognized to any State
Fund as a result of the asset transfer or on the distribution of Limited
Maturity Portfolio Common Stock to stockholders of each State Fund under
Section 361(c)(1) of the Code; (iii) under Section 1032 of the Code, no gain
or loss will be recognized to Limited Maturity Portfolio as a result of
receipt of assets of the State Funds in exchange for shares of Limited
Maturity Portfolio; (iv) in accordance with Section 354(a)(1) of the Code, no
gain or loss will be recognized to the stockholders of any State Fund on the
receipt of Limited Maturity Portfolio Common Stock in exchange for their
shares of such State Fund; (v) in accordance with Section 362(b) of the Code,
the tax basis of the assets of each State Fund in the hands of Limited
Maturity Portfolio will be the same as the tax basis of such assets in the
hands of such State Fund immediately prior to the consummation of the
Reorganization; (vi) in accordance with Section 358 of the Code, immediately
after the Reorganization, the tax basis of Limited Maturity Portfolio Common
Stock received by the stockholders of each State Fund in the Reorganization
will be equal, in the aggregate, to the tax basis of the shares of each State
Fund surrendered in exchange; (vii) in accordance with Section 1223 of the
Code, a stockholder's holding period for Limited Maturity Portfolio Common
Stock will be determined by including the period for which such stockholder
held the shares of the State Fund exchanged therefor, provided that such State
Fund shares were held as a capital asset; (viii) in accordance with Section
1223 of the Code, Limited Maturity Portfolio's holding period with respect to
the assets transferred by each State Fund will include the period for which
the assets were held by such State Fund; and (ix) the taxable year of each
State Fund will end on the effective date of the Reorganization, and pursuant
to Section 381(a) of the Code and regulations thereunder, Limited Maturity
Portfolio will succeed to and take into account certain tax attributes of such
State Fund, such as earnings and profits, capital loss carryovers and method
of accounting.
 
                                      45
<PAGE>
 
  Stockholders of the State Funds should be aware that after the
Reorganization, the distributions they receive from Limited Maturity Portfolio
will be exempt from Federal income tax but generally will not be exempt to any
significant degree from personal income tax at the state level.
 
  Stockholders should consult their tax advisers regarding the effect of the
Reorganization in light of their individual circumstances. As the foregoing
relates only to Federal income tax consequences, stockholders also should
consult their tax advisers as to the foreign, state and local tax consequences
of the Reorganization.
 
  Status as a Regulated Investment Company. The Reorganization will not affect
the status of Limited Maturity Portfolio as a RIC under the Code. Each State
Fund will terminate as a series of the Trust pursuant to the Reorganization.
 
APPRAISAL RIGHTS
 
  A stockholder of any of the State Funds who does not vote in favor of the
Reorganization may have the right under Massachusetts law to object to the
Reorganization and demand payment for his or her shares from the applicable
State Fund and an appraisal thereof upon compliance with the procedures
specified in Sections 86 through 98 of the Massachusetts Business Corporation
Law (the "Massachusetts Business Corporation Law"), which are set forth in
Exhibit III hereto. A vote against the Reorganization or the execution of a
proxy directing such a vote will not satisfy the requirements of those
provisions. A failure to vote against the Reorganization will not constitute a
waiver of such rights. The State Funds take the position that, if available,
this statutory right of appraisal may be exercised only by stockholders of
record.
 
  Section 92 of the Massachusetts Business Corporation Law provides that for
purposes of payment to any stockholder who elects to exercise his or her
statutory right of appraisal, the value of shares of such stockholder is to be
determined as of the day preceding the date of the stockholders' vote
approving the Agreement and Plan of Reorganization. However, the Commission's
Division of Investment Management has taken the position that such valuation
procedures would constitute violation of Rule 22c-1 under the Investment
Company Act (the "forward pricing" rule which in substance prohibits a
registered investment company from redeeming its shares except at a price
based on the net asset value of such shares next computed after such shares
have been tendered for redemption) and that Rule 22c-1 supersedes contrary
provisions of state statutes. Under the terms of the Agreement and Plan of
Reorganization, Limited Maturity Portfolio will assume the obligations of each
of the State Funds, if any, with respect to statutory rights of appraisal. In
the event that any stockholder elects to exercise his or her statutory right
of appraisal under Massachusetts law, it is the present intention of Limited
Maturity Portfolio to petition a court of competent jurisdiction to determine
whether such right of appraisal has been superseded by the provisions of Rule
22c-1. In such event a dissenting stockholder may not receive any payment
until disposition of any such court proceeding.
 
  For federal income tax purposes, dissenting stockholders obtaining payment
for their shares will recognize gain or loss measured by the difference
between any such payment and the tax basis for their shares. Stockholders are
advised to consult their personal tax advisers as to the tax consequences of
dissenting.
 
  Stockholders of the State Funds will, of course, continue to be able to
redeem their shares of the applicable State Fund at the current net asset
value until the close of business on the day five business days prior to the
effective date of the Reorganization. Redemption requests received by the
State Funds thereafter will be treated as requests for the redemption of
shares of Limited Maturity Portfolio Common Stock received by the stockholder
in the Reorganization.

 * Combined Fund refers to Limited Maturity Portfolio after giving effect to
   the Reorganization.
 
** Total Net Assets and Net Asset Value Per Share include the aggregate value
   of each State Fund's net assets which would have been transferred to
   Limited Maturity Portfolio had the Reorganization been consummated on July
   31, 1997. Data does not take into account expenses incurred in connection
   with the Reorganization or the actual number of shares that would have been
   issued. No assurance can be given as to how many shares of Limited Maturity
   Portfolio the stockholders of the State Funds will receive on the date the
   Reorganization takes place, and the foregoing should not be relied upon to
   reflect the number of shares of Limited Maturity Portfolio that actually
   will be received on or after such date.
 
                  INFORMATION CONCERNING THE SPECIAL MEETING
 
DATE, TIME AND PLACE OF MEETING
 
  The Meeting will be held on January 5, 1998 at the offices of MLAM, 800
Scudders Mill Road, Plainsboro, New Jersey, at 9:00 a.m., New York time.
 
SOLICITATION, REVOCATION AND USE OF PROXIES
 
  A stockholder executing and returning a proxy has the power to revoke it at
any time prior to its exercise by executing a superseding proxy or by
submitting a notice of revocation to the Secretary of the Trust. Although mere
attendance at the Meeting will not revoke a proxy, a stockholder present at
the Meeting may withdraw his proxy and vote in person.
 
  All shares represented by properly executed proxies, unless such proxies
previously have been revoked, will be voted at the Meeting in accordance with
the directions on the proxies; if no direction is indicated, the shares will
be voted "FOR" the approval of the Agreement and Plan of Reorganization.
 
  It is not anticipated that any matters other than the adoption of the
Agreement and Plan of Reorganization will be brought before the Meeting. If,
however, any other business properly is brought before the Meeting, proxies
will be voted in accordance with the judgment of the persons designated on
such proxies.
 
RECORD DATE AND OUTSTANDING SHARES
 
  The Board of Trustees of the Trust has fixed the close of business on
November 10, 1997 as the record date (the "Record Date") for the determination
of stockholders entitled to notice of, and to vote at, the Meeting or any
adjournment thereof. Stockholders on the Record Date will be entitled to one
vote for each share held, with no shares having cumulative voting rights. As
of the Record Date, for each State Fund there were issued and outstanding the
number of shares of beneficial interest, par value $.10 per share, listed
below:

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT OF THE STATE
FUNDS AND LIMITED MATURITY PORTFOLIO
   
  At the Record Date, Vincent Giordano, an officer of the Trust and of
Municipal Bond Fund, may be deemed to own beneficially 32,196 Class A shares
of the New Jersey Fund, representing 5.2% of the aggregate outstanding shares
of beneficial interest of the New Jersey Fund (18.9% of the New Jersey Fund
Class A shares outstanding). To the knowledge of the management of the Trust,
no other person owned beneficially 5% or more of the outstanding shares of any
State Fund or of any class of shares of any State Fund at the Record Date.
       
  To the knowledge of the Municipal Bond Fund, at the Record Date, no person
or entity owns beneficially 5% or more of any class of shares of Limited
Maturity Portfolio or of all classes of Limited Maturity Portfolio in the
aggregate.     
   
  On the Record Date, except as set forth above, the Trustees and officers of
the Trust as a group (12 persons) owned an aggregate of less than 1% of the
outstanding shares of any State Fund. On the Record Date, Mr. Zeikel, a
Trustee and officer of the Trust, and the other officers of the Trust owned an
aggregate of less than 1% of the outstanding shares of Common Stock of ML &
Co.     
 
  On the Record Date, the Directors and officers of the Municipal Bond Fund as
a group (12 persons) owned an aggregate of less than 1% of the outstanding
shares of Limited Maturity Portfolio Common Stock. On the Record Date, Mr.
Zeikel, a Director and officer of the Municipal Bond Fund, and the other
officers of Municipal Bond Fund owned an aggregate of less than 1% of the
outstanding shares of Common Stock of ML & Co.
 
VOTING RIGHTS AND REQUIRED VOTE
 
  For purposes of this Proxy Statement and Prospectus, each share of each
class of each State Fund is entitled to one vote. Approval of the Agreement
and Plan of Reorganization requires the affirmative vote of stockholders
representing more than 50% of the outstanding shares of each State Fund. See
Exhibit III--"Sections 86 through 98 of Chapter 156B of the Massachusetts
General Laws (the Massachusetts Business Corporation Law)" for a discussion of
dissenters' rights under Massachusetts law.
 
  If, by the time scheduled for the Meeting, sufficient votes in favor of the
Agreement and Plan of Reorganization are not received from the stockholders of
the applicable State Fund, the persons named as proxies may propose one or
more adjournments of the Meeting to permit further solicitation of proxies
from stockholders. Any such adjournment will require the affirmative vote of a
majority of the shares of the applicable State Fund present in person or by
proxy and entitled to vote at the session of the Meeting to be adjourned. The
persons named as proxies will vote in favor of any such adjournment if they
determine that adjournment and additional solicitation are reasonable and in
the interests of the applicable State Fund's stockholders.

                            ADDITIONAL INFORMATION
 
  The expenses of preparation, printing and mailing of the enclosed form of
proxy, the accompanying Notice and this Proxy Statement and Prospectus will be
borne by the State Funds and Limited Maturity Portfolio pro rata according to
the aggregate net assets of the State Fund or Limited Maturity Portfolio on
the date of the Reorganization. Such expenses are currently estimated to be
$255,000. FAM has informed the Funds that it intends to pay all expenses
relating to the Reorganization.
 
  The State Funds will reimburse banks, brokers and others for their
reasonable expenses in forwarding proxy solicitation materials to the
beneficial owners of shares of the State Funds and certain persons that the
State Funds may employ for their reasonable expenses in assisting in the
solicitation of proxies from such beneficial owners of shares of the State
Funds.
 
  In order to obtain the necessary vote at the Meeting, supplementary
solicitation may be made by mail, telephone, telegraph or personal interview
by officers of the Trust. It is expected that the cost of such supplementary
solicitation, if any, will be nominal. The Funds have retained Tritech
Services, an affiliate of ML & Co., with offices at 4 Corporate Place,
Piscataway, New Jersey, to aid in the solicitation of proxies from holders of
shares held in nominee or "street" name at a cost to be borne by FAM of
approximately $12,000, plus out-of-pocket expenses.
 
  Broker-dealer firms, including Merrill Lynch, holding State Fund shares in
"street name" for the benefit of their customers and clients will request the
instructions of such customers and clients on how to vote their shares on each
proposal before the Meeting. Broker-dealer firms, including Merrill Lynch,
will not be permitted to grant voting authority without instructions with
respect to the approval of the Agreement and Plan of Reorganization. The Trust
will include shares held of record by broker-dealers as to which such
authority has been granted in its tabulation of the total number of shares
present for purposes of determining whether the necessary quorum of
stockholders of each State Fund exists. Properly executed proxies that are
returned, but that are marked "abstain" or on which a broker-dealer has
declined to vote on any proposal ("broker non-votes") will be counted as
present for the purposes of determining a quorum. Since approval of the
Agreement and Plan of Reorganization requires the affirmative vote of
stockholders of each State Fund voting separately and representing a majority
of the outstanding shares of each State Fund, abstentions and broker non-votes
will have the same effect as a vote against the Agreement and Plan of
Reorganization.
 
  This Proxy Statement and Prospectus does not contain all of the information
set forth in the registration statements and the exhibits relating thereto
that the Municipal Bond Fund has filed with the Commission under the
Securities Act and the Investment Company Act, to which reference is hereby
made.
 
  The Trust and the Municipal Bond Fund both file reports and other
information with the Commission. Reports, proxy statements, registration
statements and other information filed by the Trust and the Municipal Bond
Fund can be inspected and copied at the public reference facilities of the
Commission in Washington, D.C. and at the New York Regional Office of the
Commission at Seven World Trade Center, New York, New York 10048. Copies of
such materials also can be obtained by mail from the Public Reference Branch,
Office of Consumer Affairs and Information Services, Securities and Exchange
Commission, Washington, D.C. 20549, at prescribed rates. The Commission
maintains a Web site (http://www.sec.gov) that contains the Statement of
Additional Information, the Limited Maturity Trust Prospectus, the Limited
Maturity Trust Statement, the Municipal Bond Fund Prospectus, the Municipal

                     AGREEMENT AND PLAN OF REORGANIZATION
 
  THIS AGREEMENT AND PLAN OF REORGANIZATION (this "Agreement") is made as of
the 24th day of November, 1997, by and between Merrill Lynch Multi-State
Limited Maturity Municipal Series Trust, a Massachusetts business trust (the
"Limited Maturity Trust"), and Merrill Lynch Municipal Bond Fund, Inc., a
Maryland corporation (the "Municipal Bond Fund").
 
                            PLAN OF REORGANIZATION
 
  The reorganization will comprise the acquisition by Limited Maturity
Portfolio (the "Limited Maturity Portfolio"), a series of the Municipal Bond
Fund, of substantially all of the assets, and the assumption of substantially
all of the liabilities, of Merrill Lynch Arizona Limited Maturity Municipal
Bond Fund (the "Arizona Fund"), Merrill Lynch Massachusetts Limited Maturity
Municipal Bond Fund (the "Massachusetts Fund"), Merrill Lynch Michigan Limited
Maturity Municipal Bond Fund (the "Michigan Fund"), Merrill Lynch New Jersey
Limited Maturity Municipal Bond Fund (the "New Jersey Fund"), Merrill Lynch
New York Limited Maturity Municipal Bond Fund (the "New York Fund") and
Merrill Lynch Pennsylvania Limited Maturity Municipal Bond Fund (the
"Pennsylvania Fund"), each a series of the Limited Maturity Trust
(collectively, the "State Funds"), in exchange solely for an equal aggregate
value of newly issued shares of Limited Maturity Portfolio's common stock,
with a par value of $.10 per share (the "Limited Maturity Portfolio Common
Stock"), and the subsequent distribution of Corresponding Shares (defined
below) of Limited Maturity Portfolio to the stockholders of the State Funds in
exchange for their shares of beneficial interest of the State Funds, each with
a par value of $.10 per share, all upon and subject to the terms hereinafter
set forth (the "Reorganization").
 
  In the course of the Reorganization, shares of Limited Maturity Portfolio
will be distributed to the stockholders of the State Funds as follows: each
holder of Class A shares of each of the State Funds will be entitled to
receive Class A shares of Limited Maturity Portfolio Common Stock. Holders of
Class B, Class C and Class D shares of each of the State Funds will be
entitled to receive Class D shares of Limited Maturity Portfolio Common Stock.
(The exchanged shares discussed above shall be referred to as "Corresponding
Shares"). The aggregate net asset value of Limited Maturity Portfolio to be
received by each stockholder of each of the State Funds will equal the
aggregate net asset value of the State Fund shares owned by such stockholder
on the Exchange Date (as defined in Section 7 of this Agreement). In
consideration therefor, on the Exchange Date, Limited Maturity Portfolio shall
acquire substantially all of the assets of each of the State Funds and assume
substantially all of the obligations and liabilities then existing, whether
absolute, accrued, contingent or otherwise of each of the State Funds. It is
intended that the Reorganization described in this Plan shall be a
reorganization within the meaning of Section 368(a)(1)(C) of the Internal
Revenue Code of 1986, as amended (the "Code"), and any successor provision.
 
  As promptly as practicable after the consummation of the Reorganization, the
Trustees of the Limited Maturity Trust shall take such action necessary to
terminate the designation of the series of the Limited Maturity Trust
representing each State Fund in accordance with the laws of the Commonwealth
of Massachusetts.
 
                                   AGREEMENT
 
  In order to consummate the Reorganization and in consideration of the
premises and the covenants and agreements hereinafter set forth, and intending
to be legally bound, the Limited Maturity Trust and the Municipal Bond Fund
hereby agree as follows:
 
  1. Representations and Warranties of the Limited Maturity Trust.
 
  The Limited Maturity Trust represents and warrants to, and agrees with, the
Municipal Bond Fund that:
 
                                      I-1
<PAGE>
 
    (a) The Limited Maturity Trust is a trust with transferable shares duly
  organized, validly existing and in good standing in conformity with the
  laws of the Commonwealth of Massachusetts, and has the power to own all of
  its assets and to carry out this Agreement. The Limited Maturity Trust has
  all necessary Federal, state and local authorizations to carry on its
  business as it is now being conducted and to carry out this Agreement.
 
    (b) The Limited Maturity Trust is duly registered under the Investment
  Company Act of 1940, as amended (the "1940 Act"), as a non-diversified,
  open-end management investment company (File No. 811-6282), and such
  registration has not been revoked or rescinded and is in full force and
  effect. The Limited Maturity Trust has elected and qualified each State
  Fund for the special tax treatment afforded regulated investment companies
  ("RICs") under Sections 851-855 of the Code at all times since inception
  and intends to continue to so qualify for the taxable year in which the
  Exchange Date occurs.
 
    (c) As used in this Agreement, the term "Investments" shall mean (i) the
  investments of each of the State Funds shown on the schedule of its
  investments as of the Valuation Time (as defined in Section 3(c) of this
  Agreement) furnished to the Municipal Bond Fund, with such additions
  thereto and deletions therefrom as may have arisen in the course of each
  State Fund's business up to the Valuation Time; and (ii) all other assets
  owned by each State Fund or liabilities incurred as of the Valuation Time,
  except that each State Fund shall retain cash, bank deposits or cash
  equivalent securities in an estimated amount necessary to (1) discharge its
  unpaid liabilities on its books at the Valuation Time (including, but not
  limited to, its income dividend and capital gains distributions, if any,
  payable for the period prior to the Valuation Time), and (2) pay such
  contingent and other liabilities as the Trustees of the Limited Maturity
  Trust reasonably shall deem to exist against such State Fund, if any, at
  the Valuation Time, for which contingent and other appropriate liability
  reserves shall be established on such State Fund's books. Each State Fund
  also shall retain any and all rights which it may have over and against any
  other person which may have accrued up to the Valuation Time. Any
  unexpended portion of the foregoing funds retained by each State Fund shall
  be disbursed by such State Fund pro rata to its stockholders upon
  consummation of the Reorganization as a final liquidating dividend.
 
    (d) The Limited Maturity Trust has full power and authority to enter into
  and perform its obligations under this Agreement. The execution, delivery
  and performance of this Agreement has been duly authorized by all necessary
  action of its Board of Trustees, and this Agreement constitutes a valid and
  binding contract enforceable in accordance with its terms, subject to the
  effects of bankruptcy, insolvency, moratorium, fraudulent conveyance and
  similar laws relating to or affecting creditors' rights generally and court
  decisions with respect thereto.
 
    (e) The Municipal Bond Fund has been furnished with a statement of assets
  and liabilities and a schedule of investments of each State Fund, each as
  of July 31, 1997, said financial statements having been examined by
  Deloitte & Touche LLP, independent public accountants. An unaudited
  statement of assets and liabilities of each State Fund and an unaudited
  schedule of investments of each State Fund, each as of the Valuation Time,
  will be furnished to the Municipal Bond Fund at or prior to the Exchange
  Date for the purpose of determining the number of shares of Limited
  Maturity Portfolio to be issued pursuant to Section 4 of this Agreement;
  and each will fairly present the financial position of the applicable State
  Fund as of the Valuation Time in conformity with generally accepted
  accounting principles applied on a consistent basis.
 
    (f) The Municipal Bond Fund has been furnished with the Limited Maturity
  Trust's Annual Report to Stockholders for the year ended July 31, 1997 and
  any subsequent Semi-Annual Report to Stockholders which may be available,
  and the financial statements appearing in such reports fairly present the
  financial position of the Limited Maturity Trust and of each State Fund as
  of the respective dates indicated, in conformity with generally accepted
  accounting principles applied on a consistent basis.
 
    (g) The Municipal Bond Fund has been furnished with the prospectus and
  statement of additional information of the Limited Maturity Trust with
  respect to the State Funds, dated November 27, 1996, and said prospectus
  and statement of additional information do not contain any untrue statement
  of a material
 
                                      I-2
<PAGE>
 
  fact or omit to state any material fact necessary to make the statements
  therein, in the light of the circumstances under which they were made, not
  misleading.
 
    (h) There are no material legal, administrative or other proceedings
  pending or, to the knowledge of the Limited Maturity Trust, threatened
  against it or any State Fund which assert liability on the part of the
  Limited Maturity Trust or any State Fund or which materially affect their
  financial condition or their ability to consummate the Reorganization.
  Neither the Limited Maturity Trust nor any State Fund is charged with or,
  to the best of the knowledge of the Limited Maturity Trust, threatened with
  any violation or investigation of any possible violation of any provisions
  of any Federal, state or local law or regulation or administrative ruling
  relating to any aspect of its business.
 
    (i) There are no material contracts outstanding to which the Limited
  Maturity Trust is a party that have not been disclosed in the N-14
  Registration Statement (as defined in subsection (o) below) or will not
  otherwise be disclosed to the Municipal Bond Fund prior to the Valuation
  Time.
 
    (j) The Limited Maturity Trust is not a party to or obligated under any
  provision of its Declaration of Trust, as amended, or its by-laws, as
  amended, or any contract or other commitment or obligation, and is not
  subject to any order or decree which would be violated by its execution of
  or performance under this Agreement.
 
    (k) No State Fund has any known liabilities of a material amount,
  contingent or otherwise, other than those shown on its statements of assets
  and liabilities referred to above, those incurred in the ordinary course of
  its business as a series of an investment company since July 31, 1997, and
  those incurred in connection with the Reorganization. As of the Valuation
  Time, the Limited Maturity Trust will advise the Municipal Bond Fund in
  writing of all known liabilities, contingent or otherwise, whether or not
  incurred in the ordinary course of business, existing or accrued as of such
  time with respect to each State Fund.
 
    (l) The Limited Maturity Trust has filed, or has obtained extensions to

material adverse effect on Municipal Bond Fund, or its stockholders; (vii)
such counsel does not have actual knowledge of any material suit, action or
legal or administrative proceeding pending or threatened against Municipal
Bond Fund, the unfavorable outcome of which would materially and adversely
affect Municipal Bond Fund; and (viii) all corporate actions required to be
taken by Municipal Bond Fund to authorize this Agreement and to effect the
Reorganization have been duly authorized by all necessary corporate actions on
the part of Municipal Bond Fund. Such opinion also shall state that (x) while
such counsel cannot make any representation as to the accuracy or completeness
of statements of fact in the N-14 Registration Statement or any amendment or
supplement thereto, nothing has come to its attention that would lead it to
believe that, on the respective effective dates of the N-14 Registration
Statement and any amendment or supplement thereto, (1) the N-14 Registration
Statement or any amendment or supplement thereto contained any untrue
statement of a material fact or omitted to state any material fact required to
be stated therein or necessary to make the statements therein not misleading;
and (2) the prospectus included in the N-14 Registration Statement contained
any untrue statement of a material fact or omitted to state any material fact
necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading; and (y) such counsel does not
express any opinion or belief as to the financial statements or other
financial or statistical data relating to Limited Maturity Portfolio contained
or incorporated by reference in the N-14 Registration Statement. In giving the
opinion set forth above, Rogers & Wells may state that it is relying on
certificates of officers of the Municipal Bond Fund with regard to matters of
fact and certain certificates and written statements of governmental officials
with respect to the good standing of the Municipal Bond Fund and on the
opinion of Wilmer, Cutler & Pickering as to matters of Maryland law.
 
  (g) That the Municipal Bond Fund on behalf of Limited Maturity Portfolio
shall have received a private letter ruling from the Internal Revenue Service
to the effect that for Federal income tax purposes (i) the transfer of
substantially all of the Investments to Limited Maturity Portfolio in exchange
solely for shares of Limited Maturity Portfolio as provided in this Agreement
will constitute a reorganization within the meaning of Section 368(a)(1)(C) of
the Code, and each State Fund and Limited Maturity Portfolio will be deemed to
be a "party" to the Reorganization within the meaning of Section 368(b); (ii)
in accordance with Section 361(a) of the Code,
 
                                     I-10

no gain or loss will be recognized to any State Fund as a result of the asset
transfer solely in exchange for shares of Limited Maturity Portfolio or on the
distribution of Limited Maturity Portfolio stock to stockholders of the
respective State Fund under Section 361(c)(1); (iii) under Section 1032 of the
Code, no gain or loss will be recognized to Limited Maturity Portfolio on the
receipt of assets of the State Funds in exchange for shares of Limited
Maturity Portfolio; (iv) in accordance with Section 354(a)(1) of the Code, no
gain or loss will be recognized to the stockholders of any State Fund on the
receipt of Corresponding Shares of Limited Maturity Portfolio in exchange for
their shares of such State Fund; (v) in accordance with Section 362(b) of the
Code, the tax basis of the assets of each State Fund in the hands of Limited
Maturity Portfolio will be the same as the tax basis of such assets in the
hands of such State Fund immediately prior to the consummation of the
Reorganization; (vi) in accordance with Section 358 of the Code, immediately
after the Reorganization, the tax basis of the Corresponding Shares of Limited
Maturity Portfolio received by the stockholders of each State Fund in the
Reorganization will be equal, in the aggregate, to the tax basis of the shares
of such State Fund surrendered in exchange; (vii) in accordance with Section
1223 of the Code, a stockholder's holding period for the Corresponding Shares
of Limited Maturity Portfolio will be determined by including the period for
which such stockholder held the shares of the State Fund exchanged therefor,
provided, that such State Fund shares were held as a capital asset; (viii) in
accordance with Section 1223 of the Code, Limited Maturity Portfolio's holding
period with respect to the assets transferred by each State Fund will include
the period for which the assets were held by such State Fund; and (ix) the
taxable year of each State Fund will end on the effective date of the
Reorganization, and pursuant to Section 381(a) of the Code and regulations
thereunder, Limited Maturity Portfolio will succeed to and take into account
certain tax attributes of such State Fund, such as earnings and profits,
capital loss carryovers and method of accounting.

connection with the Reorganization and all documents incidental thereto shall
be satisfactory in form and substance to the Limited Maturity Trust.
 
  (i) That the N-14 Registration Statement shall have become effective under
the 1933 Act, and no stop order suspending such effectiveness shall have been
instituted or, to the knowledge of the Municipal Bond Fund, contemplated by
the Commission.
 
  (j) That the Limited Maturity Trust shall have received from Deloitte &
Touche llp a letter dated as of the effective date of the N-14 Registration

effect that (i) they are independent public accountants with respect to the
Municipal Bond Fund within the meaning of the 1933 Act and the applicable
published rules and regulations thereunder; (ii) in their opinion, the
financial statements and supplementary information of Limited Maturity
Portfolio included or incorporated by reference in the N-14 Registration
Statement and reported on by them comply as to form in all material respects
with the applicable accounting requirements of the 1933 Act and the published
rules and regulations thereunder; and (iii) on the basis of limited procedures
agreed upon by the Limited Maturity Trust and the Municipal Bond Fund and
described in such letter (but not an examination in accordance with generally
accepted auditing standards) consisting of a reading of any unaudited interim
financial statements and unaudited supplementary information of Limited
Maturity Portfolio included in the N-14 Registration Statement, and inquiries
of certain officials of the Municipal Bond Fund responsible for financial and
accounting matters, nothing came to its attention that caused them to believe
that (a) such unaudited financial statements and related unaudited
supplementary information do not comply as to form in all material respects
with the applicable accounting requirements of the 1933 Act and the published
rules and regulations thereunder, (b) such unaudited financial statements are
not fairly presented in conformity with generally accepted accounting

                                     I-11

information is expressed in dollars (or percentages derived from such dollars)
(with the exception of performance comparisons, if any), if any, has been
obtained from the accounting records of the Municipal Bond Fund or from
schedules prepared by officials of the Municipal Bond Fund having
responsibility for financial and reporting matters and such information is in
agreement with such records, schedules or computations made therefrom.
 
  (k) That the Commission shall not have issued an unfavorable advisory report
under Section 25(b) of the 1940 Act, nor instituted or threatened to institute
any proceeding seeking to enjoin consummation of the Reorganization under
Section 25(c) of the 1940 Act, and no other legal, administrative or other
proceeding shall be instituted or threatened which would materially affect the
financial condition of the Municipal Bond Fund or would prohibit the
Reorganization.
 
  (l) That the Limited Maturity Trust shall have received from the Commission
such orders or interpretations as Brown & Wood LLP, as counsel to the Limited

the 1940 Act in connection with the Reorganization, provided, that such
counsel shall have requested such orders as promptly as practicable, and all
such orders shall be in full force and effect.

  The obligations of the Municipal Bond Fund hereunder shall be subject to the
following conditions:
 
  (a) That this Agreement shall have been adopted, and the Reorganization
shall have been approved, by the Board of Trustees of the Limited Maturity
Trust and by the affirmative vote of the holders of a majority of the shares
of beneficial interest of each of the State Funds issued and outstanding and
entitled to vote thereon, voting separately as a class; and that the Limited
Maturity Trust shall have delivered to the Municipal Bond Fund a copy of the
resolution approving this Agreement adopted by the Limited Maturity Trust's
Board of Trustees, and a certificate setting forth the vote of the
stockholders of each State Fund obtained, each certified by the Secretary of
the Limited Maturity Trust.
 
  (b) That the Limited Maturity Trust shall have furnished to the Municipal
Bond Fund a statement of each State Fund's assets and liabilities, with values
determined as provided in Section 4 of this Agreement, together with a
schedule of investments with their respective dates of acquisition and tax
costs, all as of the Valuation Time, certified on the Limited Maturity Trust's
behalf by its President (or any Vice President) and its Treasurer, and a
certificate of both such officers, dated the Exchange Date, certifying that as
of the Valuation Time and as of the Exchange Date there has been no material
adverse change in the financial position of each State Fund since July 31,
1997, other than changes in the Investments since that date or changes in the
market value of the Investments.

Bond Fund a certificate signed by the Limited Maturity Trust's President (or
any Vice President) and its Treasurer, dated the Exchange Date, certifying

each State Fund for the period ended July 31, 1997 (which returns originally
were prepared and filed by the Limited Maturity Trust), and that based on such
limited review, nothing came to their attention which caused them to believe
that such returns did not properly reflect, in all material respects, the
Federal, state and local income taxes of the Limited Maturity Trust for the
period covered thereby; and that for the period from August 1, 1997, to and
including the Exchange Date and for any taxable year of the Limited Maturity
Trust ending upon the termination of the last State Fund to be so terminated,

<PAGE>
 
payment of such taxes, this review to be based on unaudited financial data;
and that based on such limited review, nothing has come to their attention
which caused them to believe that the taxes paid or reserves set aside for
payment of such taxes were not adequate in all material respects for the
satisfaction of Federal, state and local taxes for the period from August 1,
1997, to and including the Exchange Date and for any taxable year of the
Limited Maturity Trust ending upon the termination of the last State Fund to

decisions with respect thereto, provided, that such counsel shall express no
opinion with respect to the application of equitable principles in any
proceeding, whether at law or in equity; (iii) the Limited Maturity Trust has
the power to sell, assign, transfer and deliver the assets transferred by it
hereunder and, upon consummation of the Reorganization in accordance with the
terms of this Agreement, the Limited Maturity Trust will have duly transferred

authority is required for the consummation by the Limited Maturity Trust of
the Reorganization, except such as have been obtained under Massachusetts law;

its Directors and officers. In giving the opinion set forth above, Bingham

do not comply as to form in all material respects with the applicable

  (b) The Municipal Bond Fund hereby agrees to indemnify and hold the Limited

fact that (i) any representations or warranties made by the Municipal Bond
Fund in this Agreement should prove false or erroneous in any material
respect, (ii) any covenant of the Municipal Bond Fund has been breached in any

Party shall conduct the defense against such claim. All costs and expenses
incurred by the Indemnifying Party in connection with such investigation and
defense of such claim shall be borne by it. These indemnification provisions
are in addition to, and not in limitation of, any other rights the parties may
have under applicable law.

                          RATINGS OF MUNICIPAL BONDS
 
DESCRIPTION OF MOODY'S INVESTORS SERVICE, INC. ("MOODY'S") MUNICIPAL BOND
RATINGS
 
AAA Bonds which are rated Aaa are judged to be of the best quality. They
    carry the smallest degree of investment risk and are generally referred
    to as "gilt edge." Interest payments are protected by a large or by an
    exceptionally stable margin and principal is secure. While the various
    protective elements are likely to change, such changes as can be
    visualized are most unlikely to impair the fundamentally strong position
    of such issues.
 
AA  Bonds which are rated Aa are judged to be of high quality by all
    standards. Together with the Aaa group they comprise what are generally
    known as high grade bonds. They are rated lower than the best bonds
    because margins of protection may not be as large as in Aaa securities
    or fluctuation of protective elements may be of greater amplitude or
    there may be other elements present which make the long-term risks
    appear somewhat larger than in Aaa securities.
 
A   Bonds which are rated A possess many favorable investment attributes and
    are to be considered as upper medium grade obligations. Factors giving
    security to principal and interest are considered adequate, but elements
    may be present which suggest a susceptibility to impairment some time in
    the future.
 
BAA Bonds which are rated Baa are considered as medium grade obligations,
    i.e., they are neither highly protected nor poorly secured. Interest
    payment and principal security appear adequate for the present but
    certain protective elements may be lacking or may be characteristically
    unreliable over any great length of time. Such bonds lack outstanding
    investment characteristics and in fact have speculative characteristics
    as well.
 
BA  Bonds which are rated Ba are judged to have speculative elements; their
    future cannot be considered as well assured. Often the protection of
    interest and principal payments may be very moderate and thereby not
    well safeguarded during both good and bad times over the future.
    Uncertainty of position characterizes bonds in this class.
 
B   Bonds which are rated B generally lack characteristics of the desirable
    investment. Assurance of interest and principal payments or of
    maintenance of other terms of the contract over any long period of time
    may be small.
 
CAA Bonds which are rated Caa are of poor standing. Such issues may be in
    default or there may be present elements of danger with respect to
    principal or interest.
 
CA  Bonds which are rated Ca represent obligations which are speculative in
    a high degree. Such issues are often in default or have other marked
    shortcomings.
 
C   Bonds which are rated C are the lowest rated class of bonds, and issues
    so rated can be regarded as having extremely poor prospects of ever
    attaining any real investment standing.
 
  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
MIG1/VMIG1, MIG2/VMIG2, MIG3/VMIG3 and MIG4/VMIG4; MIG1/VMIG1 denotes "best
quality . . . strong protection by established cash flows"; MIG2/VMIG2 denotes
"high quality" with ample margins of protection; MIG3/VMIG3 notes are of
"favorable quality . . . but . . . lacking the undeniable strength of the
preceding grades"; MIG4/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 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 ability of
rated issuers:
 
  Issuers rated Prime-1 (or supporting institutions) have a superior ability
for repayment of short-term promissory obligations. Prime-1 repayment ability
will often be evidenced by many of the following characteristics: leading
market positions in well-established industries; high rates of return on funds
employed; conservative capitalization structure with moderate reliance on debt
and ample asset protection; broad margins in earning coverage of fixed
financial charges and high internal cash generation; and well-established
access to a range of financial markets and assured sources of alternate
liquidity.
 
  Issuers rated Prime-2 (or supporting institutions) have a strong ability 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, may 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 supporting institutions) have an acceptable
ability for repayment of short-term promissory obligations. The effect of
industry characteristics and market compositions may be more pronounced.
Variability in earnings and profitability may result in changes in the level
of debt protection measurements and may require relatively high financial
leverage. Adequate alternate liquidity is maintained.
 
  Issuers rated Not Prime do not fall within any of the Prime rating
categories.
 
DESCRIPTION OF STANDARD & POOR'S RATINGS SERVICES ("STANDARD & POOR'S")
MUNICIPAL DEBT RATINGS
 
  A Standard & Poor's municipal debt rating is a current opinion of the
creditworthiness of an obligor with respect to a specific financial
obligation, a specific class of financial obligations, or a specific financial
program. It takes into consideration the creditworthiness of guarantors,
insurers or other forms of credit enhancement on the obligation.
 
  The debt rating is not a recommendation to purchase, sell or hold a
financial obligation, 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 obligors or
obtained by Standard & Poor's from other sources it considers reliable.
Standard & Poor's does not perform an audit in connection with any rating and
may, on occasion, rely on unaudited financial information. The ratings may be
changed, suspended, or withdrawn as a result of changes in, or unavailability
of, such information, or based on other circumstances.
 
  The ratings are based, in varying degrees, on the following considerations:
 
                                     II-2
<PAGE>
 
I.  Likelihood of payment--capacity and willingness of the obligor to meet
    its financial commitment on an obligation in accordance with the terms
    of the obligation;
 
II. Nature of and provisions of the obligation; and
 
III.Protection afforded by, and relative position of, the obligation in the
    event of bankruptcy, reorganization or other arrangement under the laws
    of bankruptcy and other laws affecting creditors' rights.
 
AAA Debt rated "AAA" has the highest rating assigned by Standard & Poor's.
    Capacity to meet its financial commitment on the obligation is extremely
    strong.
 
AA  Debt rated "AA" differs from the highest-rated obligations only in small
    degree. The obligor's capacity to meet its financial commitment on the
    obligation is very strong.
 
A   Debt rated "A" is somewhat more susceptible to the adverse effects of
    changes in circumstances and economic conditions than debt in higher-
    rated categories. However, the obligor's capacity to meet its financial
    commitment on the obligation is still strong.
 
BBB Debt rated "BBB" exhibits adequate protection parameters. However,
    adverse economic conditions or changing circumstances are more likely to
    lead to a weakened capacity of the obligor to meet its financial
    commitment on the obligation.
 
BB  Debt rated "BB", "B", "CCC", "CC" and "C" are regarded as having
B   significant speculative characteristics. "BB" indicates the least degree
    of speculation and "C" the highest degree of speculation. While such
CCC bonds will likely have some quality and protective characteristics,
CC  these may be outweighed by large uncertainties or major exposures to
C   adverse conditions.
 
D   Debt rated "D" is in payment default. The "D" rating category is used
    when payments on an obligation 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 or
    the taking of a similar action if payments on an obligation are
    jeopardized.
 
  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 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"
for the highest-quality obligations to "D" for the lowest. These categories
are as follows:
 
A-1 This designation 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".
 
                                     II-3
<PAGE>
 
A-3 Issues carrying this designation have an adequate capacity for timely
    payment. They are, however, more vulnerable to the adverse effects of
    changes in circumstances than obligations carrying the higher
    designations.
 
B   Issues rated "B" are regarded as having only speculative capacity for
    timely payment.
 
C   This rating is assigned to short-term debt obligations with a doubtful
    capacity for payment.
 
D   Debt rated "D" is in payment default. The "D" rating category is used
    when interest payments or principal payments are not made on the date
    due, even if the applicable grace period has not expired, unless
    Standard & Poor's believes that such payments will be made during such
    grace period.
 
  A Commercial Paper rating is not a recommendation to purchase or sell a
security. The ratings are based on current information furnished to Standard &
Poor's by the issuer and obtained by Standard & Poor's from other sources it
considers reliable. The ratings may be changed, suspended or withdrawn as a
result of changes in, or unavailability of, such information.
 
DESCRIPTION OF STANDARD & POOR'S SHORT-TERM ISSUE CREDIT RATINGS
 
  A Standard & Poor's note rating reflects the liquidity factors and market
access risks unique to notes. Notes due in three years or less will likely
receive a note rating. Notes maturing beyond three years will most likely
receive a long-term debt rating. The following criteria will be used in making
that assessment:
 
  .  Amortization schedule--the larger the final maturity relative to other
     maturities, the more likely it will be treated as a note.
 
  .   Source of payment--the more dependent the issue is on the market for
     its refinancing, the more likely it will be treated as a note.
 
  Note rating symbols are as follows:
 
SP-1 Strong capacity to pay principal and interest. An issue determined to
     possess a very strong capacity to pay debt service is given a plus (+)
     designation.
 
SP-2 Satisfactory capacity to pay principal and interest, with some
     vulnerability to adverse financial and economic changes over the term of
     the notes.
 
SP-3 Speculative capacity to pay principal and interest.
 
DESCRIPTION OF FITCH INVESTORS SERVICE, INC. ("FITCH") INVESTMENT GRADE BOND
RATINGS
 
  Fitch investment grade bond ratings provide a guide to investors in
determining the credit risk associated with a particular security. The ratings
represent Fitch's assessment of the issuer's ability to meet the obligations
of a specific debt issue or class of debt in a timely manner.
 
  The rating takes into consideration special features of the issue, its
relationship to other obligations of the issuer, the current and prospective
financial condition and operating performance of the issuer and of any
guarantor, as well as the economic and political environment that might affect
the issuer's future financial strength and credit quality.
 
                                     II-4
<PAGE>
 
  Fitch ratings do not reflect any credit enhancement that may be provided by
insurance policies or financial guaranties unless otherwise indicated.
 
  Bonds carrying the same rating are of similar but not necessarily identical
credit quality since the rating categories do not fully reflect small
differences in the degrees of credit risk.
 
  Fitch ratings are not recommendations to buy, sell or hold any security.
Ratings do not comment on the adequacy of market price, the suitability of any
security for a particular investor or the tax-exempt nature or taxability of
payments made in respect of any security.
 
  Fitch ratings are based on information obtained from issuers, other
obligors, underwriters, their experts and other sources Fitch believes to be
reliable. Fitch does not audit or verify the truth or accuracy of such
information. Ratings may be changed, suspended, or withdrawn as a result of
changes in, or the unavailability of, information or for other reasons.
 
AAA Bonds considered to be investment grade and of the highest credit
    quality. The obligor has an exceptionally strong ability to pay interest
    and repay principal, which is unlikely to be affected by reasonably
    foreseeable events.
 
AA  Bonds considered to be investment grade and of very high credit quality.
    The obligor's ability to pay interest and repay principal is very
    strong, although not quite as strong as bonds rated "AAA". Because bonds
    rated in the "AAA" and "AA" categories are not significantly vulnerable
    to foreseeable future developments, short-term debt of these issuers is
    generally rated "F-1+".
 
A   Bonds considered to be investment grade and of high credit quality. The
    obligor's ability to pay interest and repay principal is considered to
    be strong, but may be more vulnerable to adverse changes in economic
    conditions and circumstances than bonds with higher ratings.
 
BBB Bonds considered to be investment grade and of satisfactory credit
    quality. The obligor's ability to pay interest and repay principal is
    considered to be adequate. Adverse changes in economic conditions and
    circumstances, however, are more likely to have adverse impact on these
    bonds, and therefore, impair timely payment. The likelihood that the
    ratings of these bonds will fall below investment grade is higher than
    for bonds with higher ratings.
 
  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.
 
NR          Indicates that Fitch does not rate the specific issue.
 
CONDITIONAL A conditional rating is premised on the successful completion of a
            project or the occurrence of a specific event.
 
SUSPENDED   A rating is suspended when Fitch deems the amount of information
            available from the issuer to be inadequate for rating purposes.
 
WITHDRAWN
            A rating will be withdrawn when an issue matures or is called or
            refinanced and, at Fitch's discretion, when an issuer fails to
            furnish proper and timely information.
 
                                     II-5
<PAGE>
 
FITCHALERT  Ratings are placed on FitchAlert to notify investors of an
            occurrence that is likely to result in a rating change and the
            likely direction of such change. These are designated as
            "Positive", indicating a potential upgrade, "Negative", for
            potential downgrade, or "Evolving", where ratings may be raised or
            lowered. FitchAlert is relatively short-term, and should be
            resolved within 12 months.
 
  Ratings Outlook: An outlook is used to describe the most likely direction of
any rating change over the intermediate term. It is described as "Positive" or
"Negative". The absence of a designation indicates a stable outlook.
 
DESCRIPTION OF FITCH SPECULATIVE GRADE BOND RATINGS
 
  Fitch speculative grade bond ratings provide a guide to investors in
determining the credit risk associated with a particular security. The ratings
("BB" to "C") represent Fitch's assessment of the likelihood of timely payment
of principal and interest in accordance with the terms of obligation for bond
issues not in default. For defaulted bonds, the rating ("DDD" to "D") is an
assessment of the ultimate recovery value through reorganization or
liquidation.
 
  The rating takes into consideration special features of the issue, its
relationship to other obligations of the issuer, the current and prospective
financial condition and operating performance of the issuer and any guarantor,
as well as the economic and political environment that might affect the
issuer's future financial strength.
 
  Bonds that have the same rating are of similar but not necessarily identical
credit quality since rating categories cannot fully reflect the differences in
degrees of credit risk.
 
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.
 
    Bonds are in default on interest and/or principal payments. Such bonds
DDD are extremely speculative and should be valued on the basis of their
DD  ultimate recovery value in liquidation or reorganization of the obligor.
D   "DDD" represents the highest potential for recovery on these bonds, and
    "D" represents the lowest potential for recovery.
 
 
  Plus (+) or Minus (--): Plus and minus signs are used with a rating symbol
to indicate the relative position of a credit within the rating category. Plus
and minus signs, however, are not used in the "DDD," "DD" or "D" categories.
 
 
                                     II-6
<PAGE>
 
DESCRIPTION OF FITCH INVESTMENT GRADE SHORT-TERM RATINGS
 
  Fitch's short-term ratings apply to debt obligations that are payable on
demand or have original maturities of generally up to three years, including
commercial paper, certificates of deposit, medium-term notes and municipal and
investment notes.
 
  The short-term rating places greater emphasis than a long-term rating on the
existence of liquidity necessary to meet the issuer's obligations in a timely
manner.
 
  Fitch short-term ratings are as follows:
 
F-1+Exceptionally Strong Credit Quality. Issues assigned this rating are
    regarded as having the strongest degree of assurance for timely payment.
 
F-1 Very Strong Credit Quality. Issues assigned this rating reflect an
    assurance of timely payment only slightly less in degree than issues
    rated "F-1+".
 
F-2 Good Credit Quality. Issues assigned this rating have a satisfactory
    degree of assurance for timely payment, but the margin of safety is not
    as great as for issues assigned "F-1+" and "F-1" ratings.
 
F-3 Fair Credit Quality. Issues assigned this rating have characteristics
    suggesting that the degree of assurance for timely payment is adequate;
    however, near-term adverse changes could cause these securities to be
    rated below investment grade.
 
F-S Weak Credit Quality. Issues assigned this rating have characteristics
    suggesting a minimal degree of assurance for timely payment and are
    vulnerable to near-term adverse changes in financial and economic
    conditions.
 
D   Default. Issues assigned this rating are in actual or imminent payment
    default.
 
LOC The symbol "LOC" indicates that the rating is based on a letter of
    credit issued by a commercial bank.

                    SECTIONS 86 THROUGH 98 OF CHAPTER 156B
                       OF THE MASSACHUSETTS GENERAL LAWS
                 (THE MASSACHUSETTS BUSINESS CORPORATION LAW)
 
(S) 86. SECTIONS APPLICABLE TO APPRAISAL; PREREQUISITES
 
  If a corporation proposes to take a corporate action as to which any section
of this chapter provides that a stockholder who objects to such action shall
have the right to demand payment for his shares and an appraisal thereof,
sections eighty-seven to ninety-eight, inclusive, shall apply except as
otherwise specifically provided in any section of this chapter. Except as
provided in sections eighty-two and eighty-three, no stockholder shall have
such right unless (1) he files with the corporation before the taking of the
vote of the shareholders on such corporate action, written objection to the
proposed action stating that he intends to demand payment for his shares if
the action is taken and (2) his shares are not voted in favor of the proposed
action.
 
(S) 87. STATEMENT OF RIGHTS OF OBJECTING STOCKHOLDERS IN NOTICE OF MEETING;
FORM
 
  The notice of the meeting of stockholders at which the approval of such
proposed action is to be considered shall contain a statement of the rights of
objecting stockholders. The giving of such notice shall not be deemed to
create any rights in any stockholder receiving the same to demand payment for
his stock, and the directors may authorize the inclusion in any such notice of
a statement of opinion by the management as to the existence or non-existence
of the right of the stockholders to demand payment for their stock on account
of the proposed corporate action. The notice may be in such form as the
directors or officers calling the meeting deem advisable, but the following
form of notice shall be sufficient to comply with this section:
 
  "If the action proposed is approved by the stockholders at the meeting and
effected by the corporation, any stockholder (1) who files with the
corporation before the taking of the vote on the approval of such action,
written objection to the proposed action stating that he intends to demand
payment for his shares if the action is taken and (2) whose shares are not
voted in favor of such action has or may have the right to demand in writing
from the corporation (or, in the case of a consolidation or merger, the name
of the resulting or surviving corporation shall be inserted), within twenty
days after the date of mailing to him of notice in writing that the corporate
action has become effective, payment for his shares and an appraisal of the
value thereof. Such corporation and any such stockholder shall in such cases
have the rights and duties and shall follow the procedure set forth in
sections 88 to 98, inclusive, of chapter 156B of the General Laws of
Massachusetts."
 
(S) 88. NOTICE OF EFFECTIVENESS OF ACTION OBJECTED TO
 
  The corporation taking such action, or in the case of a merger or
consolidation the surviving or resulting corporation, shall, within ten days
after the date on which such corporate action became effective, notify each
stockholder who filed a written objection meeting the requirements of section
eighty-six and whose shares were not voted in favor of the approval of such
action, that the action approved at the meeting of the corporation of which he
is a stockholder has become effective. The giving of such notice shall not be
deemed to create any rights in any stockholder receiving the same to demand
payment for his stock. The notice shall be sent by registered or certified
mail, addressed to the stockholder at his last known address as it appears in
the records of the corporation.
 
(S) 89. DEMAND FOR PAYMENT; TIME FOR PAYMENT
 
  If within twenty days after the date of mailing of a notice under subsection
(e) of section eighty-two, subsection (f) of section eighty-three, or section
eighty-eight, any stockholder to whom the corporation was required to give
such notice shall demand in writing from the corporation taking such action,
or in the case of a consolidation or merger from the resulting or surviving
corporation, payment for his stock, the corporation upon which such demand is
made shall pay to him the fair value of his stock within thirty days after the
expiration of the period during which such demand may be made.
 
                                     III-1
<PAGE>
 
(S) 90. DEMAND FOR DETERMINATION OF VALUE; BILL IN EQUITY; VENUE
 
  If during the period of thirty days provided for in section eighty-nine the
corporation upon which such demand is made and any such objecting stockholder
fail to agree as to the value of such stock, such corporation or any such
stockholder may within four months after the expiration of such thirty-day
period demand a determination of the value of the stock of all such objecting
stockholders by a bill in equity filed in the superior court in the county
where the corporation in which such objecting stockholder held stock had or
has its principal office in the commonwealth.
 
(S) 91. PARTIES TO SUIT TO DETERMINE VALUE; SERVICE
 
  If the bill is filed by the corporation, it shall name as parties respondent
all stockholders who have demanded payment for their shares and with whom the
corporation has not reached agreement as to the value thereof. If the bill is
filed by a stockholder, he shall bring the bill in his own behalf and in
behalf of all other stockholders who have demanded payment for their shares
and with whom the corporation has not reached agreement as to the value
thereof, and service of the bill shall be made upon the corporation by
subpoena with a copy of the bill annexed. The corporation shall file with its
answer a duly verified list of all such other stockholders, and such
stockholders shall thereupon be deemed to have been added as parties to the
bill. The corporation shall give notice in such form and returnable on such
date as the court shall order to each stockholder party to the bill by
registered or certified mail, addressed to the last known address of such
stockholder as shown in the records of the corporation, and the court may
order such additional notice by publication or otherwise as it deems
advisable. Each stockholder who makes demand as provided in section eighty-
nine shall be deemed to have consented to the provisions of this section
relating to notice, and the giving of notice by the corporation to any such
stockholder in compliance with the order of the court shall be a sufficient
service of process on him. Failure to give notice to any stockholder making
demand shall not invalidate the proceedings as to other stockholders to whom
notice was properly given, and the court may at any time before the entry of a
final decree make supplementary orders of notice.
 
(S) 92. DECREE DETERMINING VALUE AND ORDERING PAYMENT; VALUATION DATE
 
  After hearing the court shall enter a decree determining the fair value of
the stock of those stockholders who have become entitled to the valuation of
and payment for their shares, and shall order the corporation to make payment
of such value, together with interest, if any, as hereinafter provided, to the
stockholders entitled thereto upon the transfer by them to the corporation of
the certificates representing such stock if certificated or, if
uncertificated, upon receipt of an instruction transferring such stock to the
corporation. For this purpose, the value of the shares shall be determined as
of the day preceding the date of the vote approving the proposed corporate
action and shall be exclusive of any element of value arising from the
expectation or accomplishment of the proposed corporate action.
 
(S) 93. REFERENCE TO SPECIAL MASTER
 
  The court in its discretion may refer the bill or any question arising
thereunder to a special master to hear the parties, make findings and report
the same to the court, all in accordance with the usual practice in suits in
equity in the superior court.
 
(S) 94. NOTATION ON STOCK CERTIFICATES OF PENDENCY OF BILL
 
  On motion the court may order stockholder parties to the bill to submit
their certificates of stock to the corporation for notation thereon of the
pendency of the bill and may order the corporation to note such pendency in
its records with respect to any uncertificated shares held by such stockholder
parties, and may on motion dismiss the bill as to any stockholder who fails to
comply with such order.

(S) 95. COSTS; INTEREST
 
  The costs of the bill, including the reasonable compensation and expenses of
any master appointed by the court, but exclusive of fees of counsel or of
experts retained by any party, shall be determined by the court and taxed upon
the parties to the bill, or any of them, in such manner as appears to be
equitable, except that all costs of giving notice to stockholders as provided
in this chapter shall be paid by the corporation. Interest shall be paid upon
any award from the date of the vote approving the proposed corporate action,
and the court may on application of any interested party determine the amount
of interest to be paid in the case of any stockholder.
 
(S) 96. DIVIDENDS AND VOTING RIGHTS AFTER DEMAND FOR PAYMENT
 
  Any stockholder who has demanded payment for his stock as provided in this

stockholders or to vote such stock for any purpose and shall not be entitled
to the payment of dividends or other distribution on the stock (except
dividends or other distributions payable to stockholders of record at a date
which is prior to the date of the vote approving the proposed corporate
action) unless:
 
    (1) A bill shall not be filed within the time provided in section ninety;
 
    (2) A bill, if filed, shall be dismissed as to such stockholder; or
 
    (3) Such stockholder shall with the written approval of the corporation,
  or in the case of a consolidation or merger, the resulting or surviving
  corporation, deliver to it a written withdrawal of his objections to and an
  acceptance of such corporate action.
 
Notwithstanding the provision of clauses (1) to (3), inclusive, said
stockholder shall have only the rights of a stockholder who did not so demand
payment for his stock as provided in this chapter.
 
(S) 97. STATUS OF SHARES PAID FOR
 
  The shares of the corporation paid for by the corporation pursuant to the
provisions of this chapter shall have the status of treasury stock, or in the
case of a consolidation or merger the shares or the securities of the
resulting or surviving corporation into which the shares of such objecting
stockholder would have been converted had he not objected to such
consolidation or merger shall have the status of treasury stock or securities.
 
(S) 98. EXCLUSIVE REMEDY; EXCEPTION
 
  The enforcement by a stockholder of his right to receive payment for his
shares in the manner provided in this chapter shall be an exclusive remedy
except that this chapter shall not exclude the right of such stockholder to
bring or maintain an appropriate proceeding to obtain relief on the ground
that such corporate action will be or is illegal or fraudulent as to him.

                    NOTES TO PRO FORMA FINANCIAL STATEMENTS
                                  (UNAUDITED)
 
1. SIGNIFICANT ACCOUNTING POLICIES:
 
  Merrill Lynch Municipal Bond Fund, Inc. ("the Fund") is registered under the
Investment Company Act of 1940 as a diversified, open-end management
investment company. These unaudited financial statements reflect all
adjustments which are, in the opinion of management, necessary to a fair
statement of the results for the interim period presented. All such
adjustments are of a normal recurring nature. The Fund's Portfolios offer four
classes of shares under the Merrill Lynch Select PricingSM System. Shares of
Class A and Class D are sold with a front-end sales charge. Shares of Class B
and Class C may be subject to a contingent deferred sales charge. All classes
of shares have identical voting, dividend, liquidation and other rights and
the same terms and conditions, except that Class B, Class C and Class D shares
bear certain expenses related to the account maintenance of such shares, and
Class B and Class C shares also bear certain expenses related to the
distribution of such shares. Each class has exclusive voting rights with
respect to matters relating to its account maintenance and distribution
expenditures. The following is a summary of significant accounting policies
followed by the Fund.
 
  (a) Valuation of investments--Municipal bonds and money market securities
are traded primarily in the over-the-counter markets and are valued at the
most recent bid price or yield equivalent as obtained from dealers that make
markets in such securities. Positions in future contracts and options thereon,
which are traded on exchanges, are valued at closing prices as of the close of
such exchanges. Assets for which market quotations are not readily available
are valued at fair value on a consistent basis using methods determined in
good faith by the combined Portfolios' Board of Directors, including
valuations furnished by a pricing service retained by the Fund, which may
utilize a matrix system for valuations. The procedures of the pricing service
and its valuations are reviewed by the officers of the Fund under the general
supervision of the Board of Directors.
 
  (b) Derivative financial instruments--The combined portfolio may engage in
various portfolio strategies to seek to increase its return by hedging its
portfolio against adverse movements in the debt markets. Losses may arise due
to changes in the value of the contract or if the counterparty does not
perform under the contract.
 
  . Financial futures contracts--The combined Portfolio 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 combined
    Portfolio deposits and maintains as collateral such initial margin as
    required by the exchange on which the transaction is effected. Pursuant
    to the contract, the combined Portfolio 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 combined Portfolio as unrealized gains or losses.
    When the contract is closed, the combined Portfolio 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 combined Portfolio's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute substantially all of its taxable income to its
shareholders. Therefore, no Federal income tax provision is required.
 
  (d) Security transactions and investment income--Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Interest income is recognized on the accrual basis. Discounts and market
premiums are amortized into interest income. Realized gains and losses on
security transactions are determined on the identified cost basis.
 
  (e) Deferred organization expenses and prepaid registration fees--Deferred
organization expenses are charged to expense on a straight-line basis over a
five-year period. Prepaid registration fees are charged to expenses as the
related shares are issued.

                                  (UNAUDITED)
 
 
  (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 post-October losses.
 
2. INVESTMENT ADVISORY AGREEMENT AND TRANSACTIONS WITH AFFILIATES:
 
  The combined Portfolio has entered into an Investment Advisory Agreement
with Fund Asset Management, L.P. ("FAM"). The general partner of FAM is
Princeton Services, Inc. ("PSI"), an indirect wholly-owned subsidiary of
Merrill Lynch & Co., Inc. ("ML & Co."), which is the limited partner. The
combined Portfolio has also entered into a Distribution Agreement and
Distribution Plans with Merrill Lynch Funds Distributor, Inc. ("MLFD" or
"Distributor"), a wholly-owned subsidiary of Merrill Lynch Group, Inc.
 
  FAM is responsible for the management of the Fund's portfolios and provides
the necessary personnel, facilities, equipment and certain other services
necessary to the operation of the Fund. For such services, the Limited
Maturity Portfolio pays a monthly fee based upon the aggregate daily value of
the net assets of the Portfolio and the Fund's Insured Portfolio and National
Portfolio at the following annual rates: 0.40% of these Portfolios' aggregate
average daily net assets not exceeding $250 million; 0.375% of such average
daily net assets in excess of $250 million but not exceeding $400 million;
0.35% of such average daily net assets in excess of $400 million but not
exceeding $550 million; and 0.325% of such average daily net assets in excess
of $550 million. Also, Arizona Limited Maturity, Massachusetts Limited
Maturity, Michigan Limited Maturity, New Jersey Limited Maturity, New York
Limited Maturity, and Pennsylvania Limited Maturity pay a monthly fee at the
annual rate of 0.35% of that Fund's average daily net assets.
 
  For the twelve months ended July 31, 1997 FAM had voluntarily waived
management fees and reimbursed each Portfolio for additional expenses as
follows:
