Dear Stockholder:
 
   
    We are pleased to invite you to the Annual Meeting of the Stockholders of
MuniAssets Fund, Inc. The meeting is scheduled for Monday, December 19, 1994 at
9:00 a.m. at the offices of Merrill Lynch Asset Management, L.P., 800 Scudders
Mill Road, Plainsboro, New Jersey. We hope you will be able to attend.
    
 
    At the meeting you will be asked to consider and approve a very important
proposal. Subject to stockholder approval, your Fund would acquire substantially
all the assets and assume substantially all the liabilities of the MuniBond
Income Fund, Inc. in exchange for newly issued shares of the Fund's Common
Stock, which would then be distributed to MuniBond stockholders. The MuniBond
Income Fund, Inc. is similar to your Fund in virtually every respect: both are
exchange-traded, non-diversified, closed-end management investment companies and
have the same investment objectives and comparable investment portfolios. The
Board of Directors of each Fund has unanimously approved the transaction and
recommends stockholders vote for the proposal.
 
    The combination of the two Funds should lead to efficiencies of scale, such
as reduced administrative expenses, resulting in lower expenses per share and
increased net earnings rates, greater efficiency and flexibility in portfolio
management and a more liquid trading market. The combination strengthens
management's ability to maintain tax-free dividends that you seek.
 
   
    YOUR VOTE IS IMPORTANT NO MATTER HOW MANY SHARES YOU OWN. AFTER REVIEWING
THE ENCLOSED MATERIALS, PLEASE TAKE A MOMENT TO COMPLETE, DATE AND SIGN YOUR
PROXY CARD AND MAIL IT IN THE ENCLOSED RETURN ENVELOPE TODAY. IF YOU PLAN TO
ATTEND THE MEETING, WE LOOK FORWARD TO SEEING YOU ON DECEMBER 19.
    
 
    We appreciate your continued support and confidence, and I thank you for
your goodwill.
 
                                          Very truly yours,

proposal. Subject to stockholder approval, your Fund would transfer
substantially all its assets and liabilities to the MuniAssets Fund, Inc. in
exchange for newly issued shares of that Fund, which would then be distributed
to MuniBond stockholders. If the transfer is approved, you will become a

share (the "Acquiring Fund Shares"), in connection with an Agreement and Plan of
Reorganization, dated as of November 17, 1994 (the "Agreement"), between the
Acquiring Fund and MuniBond Income Fund, Inc. (the "Acquired Fund" and, together
with the Acquiring Fund, the "Funds") whereby the Acquiring Fund would acquire
substantially all of the assets, and assume substantially all of the
liabilities, of the Acquired Fund. The number of shares of the Acquiring Fund to
be issued to the Acquired Fund would be that number having an aggregate net
asset value equal to the aggregate value of the net assets of the Acquired Fund
transferred to the Acquiring Fund. This Joint Proxy Statement Prospectus is also
being furnished to stockholders of the Acquired Fund in connection with the
solicitation of proxies by the Board of Directors of the Acquired Fund from
holders of the Acquired Fund's outstanding shares of common stock for use in the
Annual Meeting of Stockholders of the Acquired Fund (the "Acquired Fund Annual
Meeting" and, together with the Acquiring Fund Annual Meeting, the "Annual
Meetings") to be held on Monday, December 19, 1994 at 9:00 a.m., and at any and
all adjournments thereof. At the Acquired Fund Annual Meeting, stockholders will
be asked to approve the Reorganization (as defined below).
    
 
    Following receipt of the Acquiring Fund Shares, the Acquired Fund would be
dissolved and the Acquiring Fund Shares would be distributed pro rata to the
stockholders of the Acquired Fund. This transaction, consisting of the transfer
to the Acquiring Fund of substantially all of the assets of the Acquired Fund in
exchange for the Acquiring Fund Shares and the Acquiring Fund's assumption of
substantially all of the liabilities of the Acquired Fund, and the subsequent
distribution of the Acquiring Fund Shares in dissolution of the Acquired Fund,
is referred to herein as the "Reorganization."
 
   
    The terms and conditions of the Reorganization and related transactions are
more fully described in this Joint Proxy Statement--Prospectus and in the
Agreement, a copy of which is attached as Appendix I hereto.
    
 
    In addition, at the Annual Meetings, stockholders of each Fund will be asked
to consider and vote upon the election of directors and the ratification of
independent accountants for their respective Fund. The stockholders of the
Acquired Fund are being asked to vote on these additional matters in case the
Reorganization is not approved and the Acquired Fund remains a separate entity;
if the Reorganization is approved, the Acquired Fund's directors will cease to
serve, and its Investment Management Agreement will terminate, upon the
dissolution of the Acquired Fund pursuant to the Agreement.
 
    The Funds are substantially similar non-diversified, closed-end management
investment companies having identical objectives; the investment objective of
both Funds is high current income exempt from Federal income taxes by investing
in a portfolio of medium to lower grade or unrated municipal obligations the
interest on which, in the opinion of bond counsel to the issuer, is exempt from
Federal income taxes. Fund Asset Management, L.P. acts as the investment adviser
and manager for both Funds, and the same individuals constitute the Boards of
Directors of both Funds.
 
   
    The principal executive office of each Fund is located at 800 Scudders Mill
Road, Plainsboro, New Jersey 08536, and the telephone number is (609) 282-2000.
    
 
    This Joint Proxy Statement--Prospectus sets forth concisely the information
that stockholders of the Funds should know before voting on the proposals
described above and should be retained for future reference.

                                    SUMMARY
 
    The following is a summary of certain information contained elsewhere in
this Joint Proxy Statement--Prospectus. This summary is qualified in its
entirety by the more detailed information contained herein. Stockholders should
read the entire Joint Proxy Statement--Prospectus. Certain capitalized terms in
this summary are defined elsewhere in this Joint Proxy Statement--Prospectus.
 
                              THE ANNUAL MEETINGS
 
   
    This Joint Proxy Statement--Prospectus is being furnished to the
stockholders of the Acquiring Fund and the Acquired Fund in connection with the
solicitation by the Boards of Directors of the Funds of proxies to be voted at
the Funds' Annual Meetings to be held on Monday, December 19, 1994 at the
offices of Merrill Lynch Asset Management, L.P. ("MLAM"), 800 Scudders Mill
Road, Plainsboro, New Jersey. Holders of record of shares of each Fund as of the
close of business on October 21, 1994 will be entitled to notice of and to vote
at their Fund's Annual Meeting, as described elsewhere in this Joint Proxy
Statement--Prospectus.
    
 
    Stockholders of the Acquiring Fund will be asked to vote on the approval of
the issuance of additional shares of the Acquiring Fund in connection with the
Reorganization, on the election of five nominees for director and on the
ratification of the Acquiring Fund's selection of independent accountants.
 
    Stockholders of the Acquired Fund will be asked to vote on the approval of
the Reorganization, on the election of five nominees for director and on the
ratification of the Acquired Fund's selection of independent accountants.
Stockholders of the Acquired Fund will be asked to vote on these additional
matters in the event the Reorganization is not approved and the Acquired Fund
remains a separate entity.
 
    The details of each proposal to be voted on by the stockholders of each Fund
and the vote required for approval of each proposal (other than the ratification
of the Funds' selections of independent accountants) are set forth under the
description of each proposal in this Joint Proxy Statement-- Prospectus.
 
                               THE REORGANIZATION
 
   
    The Boards of Directors of the Acquiring Fund and the Acquired Fund, which
consist of the same individuals, have approved the proposed Reorganization
pursuant to which the Acquiring Fund would acquire substantially all of the
assets of the Acquired Fund in exchange for the issuance of Acquiring Fund
Shares and the assumption by the Acquiring Fund of substantially all of the
Acquired Fund's liabilities. Following receipt of the Acquiring Fund Shares, the
Acquired Fund would be dissolved and the Acquiring Fund Shares received would be
distributed to the stockholders of the Acquired Fund. The number of Acquiring
Fund Shares to be issued to the Acquired Fund would be that number having an
aggregate net asset value equal to the aggregate value of the Acquired Fund's
assets transferred to, net of the liabilities assumed by, the Acquiring Fund as
of the time such assets and liabilities are transferred
    
 
                                       2
<PAGE>
   
and assumed (such time being referred to as the "Exchange Date"). If approved by
the Funds' stockholders, the Exchange Date is expected to be the close of
business on December 19, 1994. The Agreement may be terminated and the
Reorganization abandoned, whether before or after approval by the Funds'
stockholders, at any time prior to the Exchange Date (a) by the mutual written
consent of the Boards of Directors of the Funds or (b) by either Fund if the
conditions to that Fund's obligations have not been satisfied or waived.
    
 
    As a result of the Reorganization, the assets of the Funds would be combined
and the stockholders of the Acquired Fund would become stockholders of the
Acquiring Fund. The investment objectives and policies, directors, officers and
general portfolio characteristics of the larger combined entity would be
virtually identical to that of each of the separate Funds.
 
    The Board of Directors of each Fund, including the directors of each Fund
who are not "interested persons" as that term is defined by the 1940 Act, has
concluded that the Reorganization would be in the best interests of the
stockholders of each respective Fund and that the interests of those
stockholders would not be diluted as a result of the Reorganization.
 
    Each Board of Directors approved the Reorganization because it believes that
the Reorganization should result in lower administrative expenses for the
combined Fund than is currently the case for either of the separate Funds,
greater efficiency and flexibility in portfolio management and a more liquid
trading market for the shares of the combined Fund. The Boards also recognized
the substantial similarities between the Funds. The Funds have virtually
identical investment objectives and policies; common directors, officers and
investment managers; and similar portfolio composition and trading histories.
Based on these factors, the Boards concluded that the Reorganization presents no
significant risks that would outweigh the benefits of the Reorganization.
ACCORDINGLY, THE BOARD OF EACH FUND RECOMMENDS THAT STOCKHOLDERS OF THE FUND
VOTE FOR THE APPROVAL OF THE PROPOSAL RELATING TO THE REORGANIZATION. See "The
Reorganization" and "Additional Information About the Funds."
 
             FEDERAL INCOME TAX CONSEQUENCES OF THE REORGANIZATION
   
    The Funds have jointly requested a ruling from the Internal Revenue
Service (the "IRS") with respect to the Reorganization to the effect that, among
other things, no stockholder of either Fund will recognize taxable gain or loss
upon the issuance of Acquiring Fund Shares in the Reorganization. The
consummation of the Reorganization is subject to receipt of such ruling.
Accordingly, neither Fund will recognize gain or loss in connection with the
Reorganization. In addition, stockholders of the Acquired Fund who receive
Acquiring Fund Shares pursuant to the Reorganization will recognize no gain or
loss, except with respect to the cash received for a fractional share interest,
if any. See "The Reorganization--Federal Income Tax Consequences of the
Reorganization."

             COMPARISON OF THE ACQUIRING FUND AND THE ACQUIRED FUND
 
GENERAL
 
   
    The Acquiring Fund and the Acquired Fund are both non-diversified,
closed-end management investment companies organized under the laws of the State
of Maryland. The shares of the Acquiring Fund and of the Acquired Fund are
listed and trade on the NYSE under the symbols MUA and MBD, respectively. The
shares of the Funds are identical except for their trading prices. All of the
shares of both Funds have equal non-cumulative voting rights and equal rights
with respect to dividends, assets and dissolution. The Funds' shares are fully
paid and non-assessable and have no preemptive, conversion or exchange rights.
For more detailed information about the general business and management of the
Funds, see "Additional Information About the Funds." For financial information
regarding the Funds, see "Index to Financial Statements."
    
 
INVESTMENT OBJECTIVE AND POLICIES
 
    The investment objective and policies of the Funds are virtually identical.
Each Fund's investment objective is to provide stockholders with high current
income exempt from Federal income tax by investing primarily in a portfolio of
medium to lower rated or comparable unrated municipal obligations, the interest
on which, in the opinion of bond counsel to issuer, is exempt from Federal
income taxes.
 
    Each Fund seeks to achieve its investment objective by investing at least
80% of its total assets, except during temporary defensive periods, in a
portfolio of obligations issued by or on behalf of states, territories and
possessions of the United States and their political subdivisions, agencies or
instrumentalities and paying interest which, in the opinion of bond counsel to
the issuer, is exempt from Federal income taxes ("Municipal Bonds"). The
Acquired Fund seeks to achieve its objective by investing in Municipal Bonds
with remaining maturities of greater than one year, while the Acquiring Fund is
not subject to any such maturity limitations.
 
   
    Each Fund at all times, except during temporary defensive periods, will
maintain at least 65% of its total assets in Municipal Bonds which are rated in
any one of the medium and lower rating categories of a nationally recognized
statistical rating organization or are unrated, in the case of the Acquiring
Fund, or unrated securities of comparable quality, in the case of the Acquired
Fund. In the case of Moody's Investors Service, Inc. ("Moody's"), Standard &
Poor's Corporation ("S&P") or Fitch Investors Service, Inc. ("Fitch"), these
ratings are currently Baa (Moody's) or BBB (S&P or Fitch) or lower,
respectively. There can be no assurance that the investment objective of each
Fund will be realized. See "Additional Information About the Funds--Investment
Objective and Policies."
    
 
MANAGEMENT OF THE FUNDS
 
    The Acquiring Fund and the Acquired Fund have the same directors and the
same officers. In addition, Fund Asset Management, L.P. (the "Investment
Adviser" or "FAM") acts as the investment
 
                                       4
<PAGE>
adviser for, and manages the investment and reinvestment of the assets of, both
Funds. Pursuant to the Investment Management Agreements between the Adviser and
each of the Funds, each Fund has agreed to pay the Adviser a monthly fee at an
annual rate of 0.55% of each Fund's average weekly net assets for the services
and facilities furnished by the Adviser. See "Management of the Funds--
Investment Adviser."
 
DIVIDENDS AND DISTRIBUTIONS
 
    The Funds have identical dividend policies. Each Fund's present policy,
which may be changed by its Board of Directors, is to pay dividends monthly and
to distribute substantially all of its net investment income to holders of
common stock. Net capital gains, if any, will be distributed annually to holders
of common stock. See "The Reorganization--Description of Shares To Be Issued by
the Acquiring Fund--Distributions" and "Additional Information About the
Funds--Federal Income Tax Matters Associated with Investment in the Funds."
 
AUTOMATIC DIVIDEND REINVESTMENT PLAN
 
    All dividend and capital gain distributions will be reinvested automatically
in additional shares unless a stockholder elects to receive cash. Stockholders
whose shares are held in the name of a broker or nominee should contact such
broker or nominee to confirm that they may participate in each Fund's dividend
reinvestment plan. See "The Reorganization--Description of Shares To Be Issued
by the Acquiring Fund--Automatic Dividend Reinvestment Plan."
 
SPECIAL CONSIDERATIONS REGARDING THE REORGANIZATION
 
   
    The close identity between the Acquiring Fund and the Acquired Fund that
results from both Funds having the same investment objective and Investment
Adviser and similar portfolio composition and yield should minimize any risks
that might otherwise be associated with the Reorganization. Nevertheless, the
following factors should be taken into consideration by stockholders of each
Fund in their evaluation of the Reorganization:
    
 
   
        1. Although the investment portfolios of both Funds must satisfy the
    same standards of credit quality and diversification, the actual securities
    owned by each Fund are different, as a result of which there are certain
    differences in the composition of the two investment portfolios. Of the
    securities owned by the Acquiring Fund as of May 31, 1994, 53.4% were rated
    in the medium grades by Moody's or S&P, 17.8% were rated in the lowest
    grades and 28.8% were unrated. The comparable percentages for the Acquired
    Fund were 79.7% in the medium grades, 10.4% in the lowest grades and 9.9%
    unrated.
    
 
        2. There are small differences in concentration among the categories of
    issuers of the securities held in the portfolios of the Funds. For the
    Acquiring Fund, as of May 31, 1994, the highest concentration of securities
    was in the healthcare, general obligation and electric revenue
 
                                       5
<PAGE>
    categories, accounting for 30.1%, 18.8% and 10.0% of the Fund's portfolio,
    respectively, whereas for the Acquired Fund, the highest concentration was
    in the healthcare, investor-owned utilities and industrial development
    categories, accounting for 28.2%, 20.3% and 12.6% of the portfolio.
 
   
        3. During the periods since the inception of the Funds, shares of both
    Funds have traded at a premium and a discount to net asset value. Since the
    termination of share price stabilization following each Fund's initial
    public offering, share prices for the Acquiring Fund have fluctuated between
    a maximum premium of 6.16% and a maximum discount of 20.48%, and share
    prices for the Acquired Fund have fluctuated between a maximum premium of
    5.35% and a maximum discount of 19.92%. Although there is no reason to
    believe that this pattern should be affected by the Reorganization, it is
    not possible to state whether shares of the Acquiring Fund will trade at a
    premium or discount to net asset value following the Reorganization, or
    what the extent any such premium or discount might be.

                              THE ANNUAL MEETINGS
 
GENERAL
 
   
    This Joint Proxy Statement--Prospectus is furnished in connection with the
solicitation by the Boards of Directors of the Acquiring Fund and the Acquired
Fund of proxies to be voted at the Acquiring Fund Annual Meeting and the
Acquired Fund Annual Meeting, respectively, each to be held at the offices of
Merrill Lynch Asset Management, L.P., 800 Scudders Mill Road, Plainsboro, New
Jersey, on Monday, December 19, 1994 at 9:00 a.m., and at any and all
adjournments of such meetings. The cost of preparing, printing and mailing the
enclosed proxy, accompanying notice and Joint Proxy Statement--Prospectus, and
all other costs in connection with the solicitation of proxies, will be paid by
the Funds pro rata, based on their relative assets. Additional solicitation may
be made by letter, telephone or telegraph by officers of the Funds, by officers
or employees of Merrill Lynch & Co. or the Investment Adviser, or by dealers and
their representatives. The Funds have engaged Tritech Services, an affiliate of
ML & Co to assist in the solicitation of proxies at a total estimated cost of
$3,000 for the Acquiring Fund and $3,000 for the Acquired Fund.
    
 
   
    The Board of Directors of each Fund has fixed the close of business on
October 21, 1994 as the record date (the "Record Date") for determining holders
of that Fund's shares of common stock entitled to notice of and to vote at each
respective Fund's Annual Meeting. Each stockholder will be entitled to one vote
for each Share held. At the close of business on the Record Date, there were
outstanding 4,787,055 Shares of the Acquiring Fund and 5,752,965 Shares of the
Acquired Fund. This Joint Proxy Statement--Prospectus is first being mailed to
stockholders of the Funds on or about November 23, 1994.
    
 
VOTING; PROXIES
 
    The Shares of the Acquiring Fund that are entitled to vote at the Acquiring
Fund Annual Meeting and that are represented by properly executed proxies will,
unless such proxies have been revoked, be voted in accordance with the
stockholder's instructions indicated on such proxies. If no contrary
instructions are indicated, such shares will be voted FOR approval of the
issuance of additional shares of the Acquiring Fund in connection with the
Reorganization, FOR the election of the six nominees for director and FOR
ratification of the Acquiring Fund's selection of independent accountants, as
described in this Joint Proxy Statement--Prospectus.
 
    The Shares of the Acquired Fund that are entitled to vote at the Acquired
Fund Annual Meeting and that are represented by properly executed proxies will,
unless such proxies have been revoked, be voted in accordance with the
stockholder's instructions indicated on such proxies. If no contrary
instructions are indicated, such Shares will be voted FOR approval of the
Reorganization, FOR the election of the six nominees for director and FOR
ratification of the Acquired Fund's selection of independent accountants, as
described in this Joint Proxy Statement--Prospectus.
 
    A quorum of stockholders is required to take action at each Annual Meeting.
A majority of the shares entitled to vote at each Annual Meeting, represented in
person or by proxy, will constitute a quorum of stockholders at that Annual
Meeting. Votes cast by proxy or in person at each Annual Meeting will be
tabulated by the inspectors of elections appointed for that Annual Meeting. The
 
                                       7

inspectors of election will determine whether or not a quorum is present at the
Annual Meeting. The inspectors of election will treat abstentions as shares that
are present and entitled to vote for purposes of determining a quorum.
    
 
    For purposes of determining the approval of the matters submitted to the
stockholders for a vote, abstentions will be treated as shares voted against
approval of the proposal relating to the Reorganization. Broker non-votes will
have the same effect as a vote against the proposal relating to the
Reorganization. The details of each proposal to be voted on by the stockholders
of each Fund and the vote required for approval of each proposal (other than the
ratification of the Fund's selection of independent accountants) are set forth
under the description of each proposal below. Stockholders of either Fund who
execute proxies may revoke them at any time before they are voted by filing with
their Fund a written notice of revocation, by delivering a duly executed proxy
bearing a later date, or by attending the meeting and voting in person.

                               THE REORGANIZATION
 
   
    The terms and conditions under which the proposed Reorganization may be
consummated are set forth in the Agreement and Plan of Reorganization.
Significant provisions of the Agreement are summarized below; however, this
summary is qualified in its entirety by reference to the Agreement, a copy of
which is attached as Appendix I to this Joint Proxy Statement--Prospectus.
    
 
                                    GENERAL
 
   
    The Agreement contemplates a proposed Reorganization under which (a) the
Acquiring Fund would acquire substantially all of the assets of the Acquired
Fund in exchange for the Acquiring Fund's assumption of substantially all of the
liabilities of the Acquired Fund and the issuance of Acquiring Fund Shares to
the Acquired Fund; (b) the Acquiring Fund Shares would be distributed to the
stockholders of the Acquired Fund; and (c) the Acquired Fund would be dissolved
and liquidated and its registration under the 1940 Act would be terminated. The
assets of the Acquired Fund to be acquired by the Acquiring Fund consist
primarily of Municipal Bonds, cash and other securities held in the Acquired
Fund's portfolio. The number of Acquiring Fund Shares to be issued to the
Acquired Fund would be that number having an aggregate net asset value equal to
the aggregate value of the Acquired Fund's assets transferred to, net of the
liabilities assumed by, the Acquiring Fund as of the time such assets and
liabilities are transferred and assumed (the "Exchange Date"). If the proposals
relating to the Reorganization are approved, the Exchange Date is expected to be
the close of business on December 19, 1994, the date of the Annual Meetings.
    
 
    If the Reorganization is approved, the assets of the Funds would be combined
and the investment objective and policies and general portfolio characteristics
of the larger combined entity would be virtually identical to that of each of
the separate Funds. The Boards of Directors of the Funds believe that this will
provide benefits to stockholders of both Funds as described below under "Reasons
for the Proposed Reorganization."
 
    The result of the Reorganization would be that (a) the Acquiring Fund would
add to its gross assets substantially all of the assets of the Acquired Fund,
other than cash to be used to pay expenses of the Acquired Fund and to make a
final distribution of ordinary income and capital gains to the stockholders of
the Acquired Fund as of the Exchange Date and (b) the stockholders of the
Acquired Fund as of the Exchange Date would become stockholders of the Acquiring
Fund. See "Description of Shares To Be Issued by the Acquiring Fund" and
"Comparison of Rights of Holders of Shares of the Acquiring Fund and the
Acquired Fund" for a description of the rights of such stockholders. For Federal
income tax reasons, the Acquired Fund must distribute all of its income and
capital gains prior to the end of its fiscal year, which would occur at the
Exchange Date.
 
                                       9
<PAGE>
    If the stockholders of the Funds approve the proposals relating to the
Reorganization, the assets of the Acquired Fund to be acquired by the Acquiring
Fund will include without limitation all cash (except as necessary to pay the
liabilities retained by the Acquired Fund or described in the next sentence),
cash equivalents, Municipal Bonds and other securities, receivables and other
property owned by the Acquired Fund. The Acquiring Fund will assume from the
Acquired Fund all debts, liabilities, obligations and duties of the Acquired
Fund, other than (a) certain expenses incurred by the Acquired Fund in
connection with the Reorganization and (b) the Acquired Fund's obligation to
distribute any ordinary income and capital gains accrued as of the Exchange
Date.
 
   
    The value of the Acquired Fund's assets to be acquired and the liabilities
to be assumed by the Acquiring Fund and the net asset value per share for the
shares to be issued by the Acquiring Fund will be determined by The Bank of New
York ("BONY"), the custodian for both of the Funds, as of the Exchange Date. To
determine the net asset value per share for the Funds, the value of the
securities held by each Fund plus any cash or other assets (including interest
and dividends accumulated but not yet received) minus all liabilities (including
accrued expenses) is divided by the total number of shares outstanding at such
time. Expenses, including the fees payable to the Investment Adviser, are
accrued daily. The number of Acquiring Fund Shares to be issued to the Acquired
Fund pursuant to the Reorganization will be calculated based on the
determinations of BONY.
    

    As soon as practicable after the Exchange Date, the Acquired Fund would
dissolve and distribute the Acquiring Fund Shares received by it pro rata to its
stockholders of record in exchange for such stockholders' interests in the
Acquired Fund. Such dissolution and distribution would be accomplished by
opening accounts on the books of the Acquiring Fund in the names of the
stockholders of the Acquired Fund and transferring to those stockholder accounts
the Acquiring Fund Shares previously credited on those books to the account of
the Acquired Fund. Each stockholder account would represent the respective pro
rata number of Acquiring Fund Shares (rounded down, in the case of fractional
Shares, to the next largest number of whole Shares) due such Acquired Fund
stockholder. No fractional Shares will be issued. In lieu thereof, the Acquired
Fund's transfer agent, The Bank of New York, will aggregate all fractional
shares and sell the resulting whole shares on the NYSE for the account of all
holders of fractional interests, and each such holder will be entitled to his or
her pro rata share of the proceeds of such sale upon surrender of his or her
Acquired Fund Share certificates. See "Surrender and Exchange of Acquired Fund
Share Certificates" for a description of the procedures to be followed by
Acquired Fund stockholders to obtain their Acquiring Fund Shares (and cash in
lieu of fractional Shares, if any).
 
    Accordingly, as a result of the Reorganization, every stockholder of the
Acquired Fund would own Acquiring Fund Shares that, except for cash payments
received in lieu of fractional shares, would have an aggregate net asset value
immediately after the Exchange Date equal to the aggregate net asset value of
that stockholder's Acquired Fund Shares immediately prior to the Exchange Date.
Since the Acquiring Fund Shares would be issued at net asset value in exchange
of net assets of the Acquired Fund having a value equal to the aggregate net
asset value of those shares, the net asset value per share of the Acquiring Fund
Shares should remain virtually unchanged by the Reorganization. Thus, the
 
                                       10
<PAGE>
Reorganization should result in virtually no dilution of net asset value of any
stockholder's holdings, other than to reflect the cost to effect the
Reorganization. See "Pro Forma Financial Information." However, as a result of
the Reorganization, a stockholder of either Fund would likely hold a reduced
percentage of ownership in the larger combined entity than he or she did in
either of the constituent Funds.
 
    The Agreement may be terminated and the Reorganization abandoned, whether
before or after approval by the Funds' stockholders, at any time prior to the
Exchange Date (a) by the mutual written consent of the Boards of Directors of
the Funds or (b) by either Fund if the conditions to that Fund's obligations
under the Agreement have not been satisfied or waived and it reasonably appears
that such conditions will not be satisfied. Under Maryland law and each Fund's
Articles of Incorporation/By-Laws, stockholders of the Funds do not have
appraisal rights with respect to the Reorganization.
 
                    REASONS FOR THE PROPOSED REORGANIZATION
 
    The Board of Directors of the Acquiring Fund and the Board of Directors of
the Acquired Fund, which consist of the same directors, each believes that the
Reorganization is in the best interests of the stockholders of its respective
Fund and unanimously recommends that the stockholders of that Fund vote FOR
approval of the proposal relating to the Reorganization.
 
    In approving the Reorganization, the Boards identified certain benefits that
are likely to result from combining the Funds, including lower expenses per
share, greater efficiency and flexibility in portfolio management and a more
liquid trading market for the shares of the combined Fund. The Boards also
considered the possible risks and costs of combining the Funds and determined
that the Reorganization is likely to provide benefits to the stockholders of
both Funds that outweigh the costs and that there are no significant risks.
 
    The larger Fund that would result from the Reorganization would have a much
larger asset base than either Fund has currently. Based on data presented by the
Investment Adviser, the Boards believe that administrative expenses for a larger
combined Fund will be less than the aggregate expenses for the two smaller
Funds, resulting in a lower expense ratio for the combined Fund and higher
earnings for stockholders.
 
    Management projections estimate that the Acquiring Fund will have net assets
in excess of $150 million upon completion of the Reorganization. A larger asset
base should provide benefits in portfolio management. The Acquiring Fund after
the Reorganization should be able to purchase large amounts of Municipal Bonds
at more favorable prices than either of the Funds separately and, with this
greater purchasing power, request improvements in the terms of Municipal Bonds
(e.g., added indenture provisions covering call protection, sinking funds,
audits for the benefit of large holders) prior to purchase.
 
                                       11
<PAGE>
    In approving the Reorganization, the Boards of Directors of the Funds
determined that the interests of existing stockholders of the Funds would not be
diluted as a result of the Reorganization. See "Pro Forma Financial
Information." Although the Reorganization is expected to result in a reduction
in net asset value per Acquiring Fund Share (and per Acquired Fund Share
equivalent) of approximately $.02 as a result of the estimated costs of the
Reorganization, management of the Funds advised the Boards that it expects that
such costs will be recovered within 18 months after the Exchange Date. See
"Expenses Associated with the Reorganization."
 
    In approving the Reorganization, the Boards considered the fact that the
Reorganization should not be expected to have an adverse effect on the financial
status and ongoing performance of each Fund. The Boards also examined the
relative credit strength, maturity characteristics, mix of type and purpose, and
yield of the Funds' portfolios of Municipal Bonds and the costs involved in a
transaction such as the Reorganization. The Boards noted the many similarities
between the Funds, including their virtually identical investment objectives and
investment policies, their common management and their similar portfolios of
Municipal Bonds. Based on these factors, the Boards concluded that the
Reorganization presents no significant risks and minimal costs (including
relatively minor legal, accounting and administrative costs, most of which have
already been incurred in evaluating and analyzing the Reorganization) that would
outweigh the benefits discussed above.
 
                                 VOTE REQUIRED
 
   
    Consummation of the Reorganization requires the approval of the stockholders
of both Funds. Stockholders of the Acquiring Fund are being asked to approve the
issuance of additional shares of the Acquiring Fund in connection with the
Reorganization. Adoption of this proposal will require the affirmative vote of
the holders of at least a majority of the Acquiring Fund Shares voting on the
proposal, provided that the total vote cast on the proposal represents over 50%
in interest of all shares of the Acquiring Fund entitled to vote on the
proposal.
    
 
   
    Stockholders of the Acquired Fund are being asked to approve the
Reorganization, whereby (a) the Acquired Fund would transfer substantially all
of its assets to the Acquiring Fund in exchange for shares of the Acquiring Fund
and the assumption of substantially all of the Acquired Fund's liabilities by
the Acquiring Fund; and (b) the Acquiring Fund Shares received by the Acquired
Fund would be distributed to stockholders of the Acquired Fund in dissolution of
the Acquired Fund. Adoption of this proposal will require the affirmative vote
of the holders of at least a majority of the shares of the Acquired Fund
entitled to vote on the proposal.

<PAGE>
            DESCRIPTION OF SHARES TO BE ISSUED BY THE ACQUIRING FUND
 
GENERAL
 
   
    The Articles of Incorporation of the Acquiring Fund (the "Acquiring Fund's
Articles") authorizes the issuance of 200,000,00 shares of capital stock in a
single class, par value $.10 per share. As of October 21, 1994, there were
issued and outstanding 4,787,055 Acquiring Fund Shares. If the Reorganization is
approved, at the Exchange Date the Acquiring Fund will issue additional
Acquiring Fund Shares. The number of such additional Acquiring Fund Shares will
be based on the relative net asset values of the Funds as of the Exchange Date;
based on the relative net asset values as of May 31, 1994, the Acquiring Fund
would have issued approximately 6,610,098 additional Acquiring Fund Shares if
the Reorganization had occurred as of that date. The terms of the Shares to be
issued pursuant to the Reorganization will be identical to the terms of the
Acquiring Fund Shares that are outstanding. All of the Acquiring Fund's Shares
have equal non-cumulative voting rights and equal rights with respect to
dividends, assets and dissolution. The Acquiring Fund Shares are fully paid and
non-assessable and have no preemptive, conversion or exchange rights.
    
 
DIVIDEND AND DISTRIBUTIONS
 
    It is the Acquiring Fund's present policy, which may be changed by the Board
of Directors, to pay dividends monthly and to distribute substantially all of
its net investment income to holders of common stock. Net capital gains, if any,
will be distributed annually to holders of common stock. The Acquiring Fund's
distribution level is determined by the Board of Directors of the Acquiring Fund
after giving consideration to a number of factors, including the Acquiring
Fund's undistributed net investment income and historical and projected
investment income and expenses. Net income of the Acquiring Fund consists of all
interest income accrued on portfolio assets, less all expenses of the Acquiring
Fund. Expenses of the Acquiring Fund are accrued each day.
 
AUTOMATIC DIVIDEND REINVESTMENT PLAN
 
   
    Pursuant to the Acquiring Fund's Automatic Dividend Reinvestment Plan (the
"Plan"), unless a stockholder otherwise elects, all dividend and capital gain
distributions will be automatically reinvested by The Bank of New York, as agent
for stockholders in administering the Plan (the "Plan Agent"), in additional
shares of Common Stock of the Acquiring Fund. Stockholders who elect not to
participate in the Plan will receive all distributions in cash paid by check
mailed directly to the stockholder of record (or, if the shares are held in
street or other nominee name then to such nominee) by The Bank of New York, as
dividend paying agent. Whether such participants may elect not to participate in
the Plan is completely voluntary and may be terminated or resumed at any time
without penalty by written notice if received by the Plan Agent not less than
ten days prior to any dividend record date; otherwise such termination will be
effective with respect to any subsequently declared dividend or distribution.
    
 
    Whenever the Acquiring Fund declares an income dividend or a capital gains
distribution (collectively referred to as "dividends") payable either in shares
or in cash, non-participants in the Plan will receive cash and participants in
the Plan will receive the equivalent in shares of Common Stock. The shares will
be acquired by the Plan Agent for the participant's account, depending upon the
circumstances described below, either (i) through receipt of additional unissued
but authorized shares
 
                                       13
<PAGE>
   
of Common Stock from the Acquiring Fund ("newly issued shares") or (ii) by
purchase of outstanding shares of Common Stock on the open market ("open-market
purchases") on the NYSE or elsewhere. If on the payment date for the dividend,
the net asset value per share of the Common Stock is equal to or less than the
market price per share of the Common Stock plus estimated brokerage commissions
(such condition being referred to herein as "market premium"), the Plan Agent
will invest the dividend amount in newly issued shares on behalf of the
participant. The number of newly issued shares of Common Stock to be credited to
the participant's account will be determined by dividing the dollar amount of
the dividend by the net asset value per share on the date the shares are issued,
provided that the maximum discount from the then current market price per share
on the date of issuance may not exceed 5%. If on the dividend payment date the
net asset value per share is greater than the market value (such condition being
referred to herein as "market discount"), the Plan Agent will invest the
dividend amount in shares acquired on behalf of the participant in open-market
purchases.
    
 
   
    In the event of a market discount on the dividend payment date, the Plan
Agent will have until the last business day before the next date on which the
shares trade on an "ex-dividend" basis or in no event more than 30 days after
the dividend payment date (the "last purchase date") to invest the dividend
amount in shares acquired in open-market purchases. It is contemplated that the
Acquiring Fund will pay monthly income dividends. Therefore, the period during
which open-market purchases can be made will exist only from the payment date of
the dividend through the date before the next "ex-dividend" date which typically
will be approximately ten days. If, before the Plan Agent has completed its
open-market purchases, the market price of a share of Common Stock exceeds the
net asset value per share, the average per share purchase price paid by the Plan
Agent may exceed the net asset value of the Acquiring Fund's shares, resulting
in the acquisition of fewer shares than if the dividend had been paid in newly
issued shares on the dividend payment date. Because of the foregoing difficulty
with respect to open-market purchases, the Plan provides that if the Plan Agent
is unable to invest the full dividend amount in open-market purchases during the
purchase period or if the market discount shifts to a market premium during the
purchase period, the Plan Agent will cease making open-market purchases and will
invest the uninvested portion of the dividend amount in newly issued shares at
the close of business on the last purchase date.
    
 
    The Plan Agent maintains all stockholders' accounts in the Plan and
furnishes written confirmation of all transactions in the account, including
information needed by stockholders for tax records. Shares in the account of
each Plan participant will be held by the Plan Agent in non-certificated form in
the name of the participant, and each stockholder's proxy will include those
shares purchased or received pursuant to the Plan. The Plan Agent will forward
all proxy solicitation materials to participants and vote proxies for shares
held pursuant to the Plan in accordance with the instructions of the
participants.
 
    In the case of stockholders such as banks, brokers or nominees which hold
shares for others who are the beneficial owners, the Plan Agent will administer
the Plan on the basis of the number of shares certified from time to time by the
record stockholders as representing the total amount registered in the record
stockholder's name and held for the account of beneficial owners who are to
participate in the Plan.
 
   
    There will be no brokerage charges with respect to shares issued directly by
the Acquiring Fund as a result of dividends or capital gains distributions
payable either in shares or in cash. However, each
    
 
                                       14
<PAGE>
participant will pay a pro rata share of brokerage commissions incurred with
respect to the Plan Agent's open-market purchases in connection with the
reinvestment of dividends.
 
   
    Stockholders participating in the Plan may receive benefits not available to
stockholders not participating in the Plan. If the market price plus commissions
of the Acquiring Fund's shares is above the net asset value, participants in the
Plan will receive shares of the Acquiring Fund at less than they could otherwise
purchase them and will have shares with a cash value greater than the value of
any cash distribution they would have received on their shares. If the market
price plus commissions is below the net asset value, participants will receive
distributions on shares with a net asset value greater than the value of any
cash distributions they would have received on their shares. However, there may
be insufficient shares available in the market to make distributions in shares
at prices below the net asset value. Also, since the Acquiring Fund does not
redeem its shares, the price on resale may be more or less than the net asset
value. See "Taxes" for a discussion of tax consequences of the Plan.
    
 
   
    Experience under the Plan may indicate that changes are desirable.
Accordingly, the Acquiring Fund reserves the right to amend or terminate the
Plan. There is no direct service charge to participants in the Plan; however,
the Acquiring Fund reserves the right to amend the Plan to include a service
charge payable by the participants.
    
 
    All correspondence concerning the Plan should be directed to the Plan Agent
at 101 Barclay Street, New York, New York 10286.
 
      CERTAIN PROVISIONS IN THE ACQUIRING FUND'S ARTICLES OF INCORPORATION
 
    The Acquiring Fund's Articles of Incorporation include provisions that could
have the effect of limiting the ability of other entities or persons to acquire
control of the Acquiring Fund or to change the composition of its Board of
Directors and could have the effect of depriving stockholders of an opportunity
to sell their shares at a premium over prevailing market prices by discouraging
a third party from seeking to obtain control of the Acquiring Fund. A director
may be removed from office with or without cause and only by a vote of the
holders of at least 66 2/3% of the votes entitled to be voted on the matter.
 
    In addition, the Articles of Incorporation require the favorable vote of the
holders of at least 66 2/3% of the Acquiring Fund's shares of capital stock,
then entitled to be voted, voting as a single class, to approve, adopt or
authorize the following:
 
        (i) a merger or consolidation or statutory share exchange of the
    Acquiring Fund with other corporations,
 
   
        (ii) a sale of all or substantially all of the Acquiring Fund's assets
    (other than in the regular course),
    
 
   
        (iii) a liquidation or dissolution of the Acquiring Fund,
    
 
   
unless such action has been approved, adopted or authorized by the
affirmative vote of at least two-thirds of the total number of Directors fixed
in accordance with the by-laws in which case the affirmative vote of a majority
of the Acquiring Fund's shares of capital stock is required.
    
 
                                       15
<PAGE>
   
    In addition, the conversion of the Acquiring Fund to an open-end investment
company would require an amendment to the Acquiring Fund's Articles of
Incorporation. The amendment would have to be declared advisable by the Board of
Directors prior to its submission to stockholders. Such an amendment would
require the favorable vote of the holders of at least 66 2/3 of the Acquiring
Fund's outstanding shares of capital stock entitled to be voted on the matter,
voting as a single class (or a majority of such shares if the amendment was
previously approved, adopted or authorized by at least two-thirds of the total
number of Directors fixed in accordance with the by-laws). Such a vote also
would satisfy a separate requirement in the 1940 Act that the change be approved
by the stockholders. Stockholders of an open-end investment company may require
the company to redeem their shares of common stock at any time (except in
certain circumstances as authorized by or under the 1940 Act) at their net asset
value, less such redemption charge, if any, as might be in effect at the time of
a redemption. All redemptions will be made in cash. If the Acquiring Fund is
converted to an open-end investment company, it could be required to liquidate
portfolio securities to meet requests for redemption and the Common Stock would
no longer be listed on a stock exchange.
    
 
   
    The Board of Directors has determined that the 66 2/3 voting requirements
described under "Certain Provisions in the Acquiring Fund's Articles of
Incorporation," which are greater than the minimum requirements under Maryland
law or the 1940 Act, are in the best interests of stockholders generally.
Reference should be made to the Acquiring Fund's Articles of Incorporation on
file with the Securities and Exchange Commission for the full text of these
provisions.
    
 
                   COMPARISON OF RIGHTS OF HOLDERS OF SHARES
                  OF THE ACQUIRING FUND AND THE ACQUIRED FUND
 
    The terms of the Acquiring Fund Shares to be issued in the Reorganization,
as described above, are identical to the terms of the outstanding shares of the
Acquired Fund. Moreover, each of the Funds is organized as a management
investment company under the laws of the State of Maryland pursuant to virtually
identical Articles of Incorporation. Therefore, the rights of holders of the
Acquiring Fund Shares to be received by Acquired Fund stockholders in the
Reorganization will be identical to their rights as holders of Acquired Fund
Shares. The shares will simply represent an equity ownership in a larger
combined entity after the Reorganization. The full text of each Fund's Articles
of Incorporation is on file with the Commission and may be obtained as described
under "Available Information." The terms of the Acquiring Fund's Automatic
Dividend Reinvestment Plan also are identical to the terms of the Acquired
Fund's Automatic Dividend Reinvestment Plan.
 
           SURRENDER AND EXCHANGE OF ACQUIRED FUND SHARE CERTIFICATES
 
   
    After the Exchange Date, each holder of an outstanding certificate or
certificates formerly representing shares of the Acquired Fund will be entitled
to receive, upon surrender of his or her certificates, a certificate or
certificates representing the number of Acquiring Fund Shares distributable with
respect to such holder's shares of the Acquired Fund, together with cash in lieu
of any fractional shares. Promptly after the Exchange Date, the Transfer Agent
will mail to each holder of certificates formerly representing shares of the
Acquired Fund a letter of transmittal for use in surrendering his or
    
 
                                       16
<PAGE>
her certificates for certificates representing shares of the Acquiring Fund and
cash in lieu of any fractional shares.
 
    PLEASE DO NOT SEND IN ANY SHARE CERTIFICATES AT THIS TIME. UPON CONSUMMATION
OF THE REORGANIZATION, ACQUIRED FUND STOCKHOLDERS WILL BE FURNISHED INSTRUCTIONS
FOR EXCHANGING THEIR ACQUIRED FUND SHARE CERTIFICATES FOR ACQUIRING FUND SHARE
CERTIFICATES AND, IF APPLICABLE, CASH IN LIEU OF FRACTIONAL SHARES.
 
    From and after the Exchange Date, certificates formerly representing shares
of the Acquired Fund will be deemed for all Fund purposes to evidence ownership
of the number of full Acquiring Fund Shares distributable with respect to such
shares of the Acquired Fund in the Reorganization, provided that until such
Acquired Fund certificates have been so surrendered, no dividends payable to the
holders of record of Acquiring Fund Shares as of any date subsequent to the
Exchange Date will be paid to the holders of such outstanding Acquired Fund
Share certificates. Dividends payable on Acquiring Fund Shares to holders of
record as of any date after the Exchange Date and prior to the exchange of
certificates by any Acquired Fund stockholder will be paid to such stockholder,
without interest, at the time such stockholder surrenders his or her Acquired
Fund Share certificates for exchange.
 
    From and after the Exchange Date, there will be no transfers on the stock
transfer books of the Acquired Fund. If, after the Exchange Date, certificates
representing shares of the Acquired Fund are presented to the Acquired Fund,
they will be cancelled and exchanged for certificates representing the Acquiring
Fund Shares and the cash in lieu of fractional shares, if any, distributable
with respect to such Acquired Fund Shares in the Reorganization.
 
                  EXPENSES ASSOCIATED WITH THE REORGANIZATION
 
   
    In evaluating the proposed Reorganization, management of the Funds estimated
the amount of additional expenses the Funds would incur, including additional
NYSE listing fees, Commission registration fees, legal and accounting fees and
increased proxy and distribution costs. These estimates were based in part on
historical expense information regarding expenses incurred by other funds
managed by the Fund's management in preparation for previous stockholder
meetings. The aggregate amount of estimated expenses, excluding Commission
registration fees and annual NYSE fees which will be borne by the Acquiring
Fund after the Reorganization, was then allocated to the Acquired Fund and
the Acquiring Fund based on their respective asset size.
    
 
    Reorganization expenses of the Acquiring Fund and the Acquired Fund have
been or will be expensed prior to the Exchange Date. Management of the Funds
expects that reduced administrative expenses resulting from the Reorganization
should allow the Acquiring Fund to recover the projected costs of the
Reorganization within approximately 18 months after the Exchange Date.
 
                                       17
<PAGE>
             FEDERAL INCOME TAX CONSEQUENCES OF THE REORGANIZATION
 
   
    The Funds have jointly requested a ruling from the IRS with respect to
the Reorganization to the effect that, among other things, no stockholder of
the acquired Fund will recognize taxable gain or loss upon the issuance of 
Acquiring Fund Shares in the Reorganization. The consummation of the 
Reorganization is subject to receipt of such ruling. Based upon representations
by the Acquired Fund that the Acquired Fund has qualified, and by the Acquiring 
Fund that the Acquiring Fund has qualified, as a regulated investment company 
under the Internal Revenue Code of 1986, as amended (the "Code") for the 
taxable period up to and including the business day prior to the date on which 
the Reorganization takes place, the status of each Fund as a regulated 
investment company will not be affected as a result of the Reorganization, 
except that upon the liquidation of the Acquired Fund in connection with the 
Reorganization its regulated investment company status will terminate. The 
following discussion summarizes the anticipated federal income tax treatment 
to stockholders of the Acquired Fund.
    
 
    Exchange of Acquired Fund Shares Solely for Acquiring Fund Shares. A
stockholder of the Acquired Fund who receives Acquiring Fund Shares pursuant to
the Reorganization will recognize no gain or loss, except with respect to the
cash received for a fractional share interest, if any. See "Fractional Share
Interests" below.
 
    The aggregate basis of the Acquiring Fund Shares received by a stockholder
of the Acquired Fund (including any fractional share interest to which he or she
may be entitled) will be the same as the stockholder's aggregate basis in the
Acquired Fund Shares surrendered in exchange therefor, decreased by any cash
received and increased by the amount of gain recognized on the exchange.
 
    The holding period of the Acquiring Fund Shares received by a stockholder of
the Acquired Fund (including any fractional share interest to which he or she
may be entitled) will include the period during which the stockholder's Acquired
Fund Shares were held, provided such Acquired Fund Shares were held as a capital
asset at the Exchange Date.
 
    Fractional Share Interests. No fractional Acquiring Fund Shares will be
issued in the Reorganization. Cash payments received by Acquired Fund
stockholders in lieu of a fractional Acquiring Fund Share will be treated as
received by such stockholders as a distribution in redemption by the Acquiring
Fund of that fractional share interest and will be treated as a distribution in
full payment in exchange for the fractional share interest, resulting in a
capital gain or loss assuming the Acquired Fund Shares exchanged for cash in
lieu of the fractional shares were held as a capital asset at the Exchange Date.
 
    THE FOREGOING IS INTENDED TO BE ONLY A SUMMARY OF THE PRINCIPAL FEDERAL
INCOME TAX CONSEQUENCES OF THE REORGANIZATION AND SHOULD NOT BE CONSIDERED TO BE
TAX ADVICE. THERE CAN BE NO ASSURANCE THAT THE INTERNAL REVENUE SERVICE WILL
CONCUR ON ALL OR ANY OF THE ISSUES DISCUSSED ABOVE. ACQUIRED FUND STOCKHOLDERS
ARE URGED TO CONSULT THEIR OWN TAX ADVISERS REGARDING THE FEDERAL, STATE AND
LOCAL TAX CONSEQUENCES WITH RESPECT TO THE FOREGOING MATTERS AND ANY OTHER
CONSIDERATIONS WHICH MAY BE APPLICABLE TO THEM.

EXPLANATORY NOTES
 
(1) The Acquiring Fund was organized in April 1993 and commenced operations on
    June 25, 1993. The Acquired Fund was organized in August 1993 and commenced
    operations on October 29, 1993.
 
(2) Represents estimated reduction in operating expenses, including audit,
    legal, custodian, stock exchange and report printing. The Acquiring Fund (As
    Adjusted) would have a much larger asset base than either Fund currently
    has. Certain operating expenses would have been reduced had they been
    applied to the larger asset base for one Fund, rather than to two smaller
    separate Funds.

            N/R--Investment is not rated.
 
(p) Rating is provisional. A provisional rating assumes the successful
    completion of the project being financed by the issuance of the bonds being
    rated and indicates that payment of debt service requirements is largely or
    entirely dependent upon the successful and timely completion of the project.
 
   
+  The security has a maturity of more than one year but has variable rate and
   demand features which qualify it as a short-term security. The rate disclosed
   is that currently in effect. This rate changes periodically based on market
   conditions or a specified market index.

                             ELECTION OF DIRECTORS
 
    At the Meeting, the Board of Directors of each of the Funds will be elected
to serve for terms ending on the dates of subsequent Annual Meetings of
Stockholders as follows--Class I in 1995, Class II in 1996, and Class III in
1997--or until their successors are duly elected and qualified, or in the case
of the Acquired Fund, until the earlier dissolution of the Acquired Fund. It is
the intention of the persons named in the accompanying form of Proxy to vote, on
behalf of the stockholders, for the election of the six nominees listed below as
Directors of each Fund, divided into three classes as follows:
 
       CLASS I              CLASS II            CLASS III
       -------------        ------------        -------------------

       Harry Woolf          Walter Mintz        Stephen B. Swensrud
 
    All of the Directors have been members of the Board of Directors since each
Fund's initial public offering in 1993, except Joe Grills, who has been a member
of the Board of Directors of the Acquiring Fund since January 1994. Each of the
nominees for Director has consented to be named in this Proxy Statement and to
serve as a Director if elected. The members of the Board of Directors and the
nominees for election to the Board are the same for both Funds. The Board of
Directors knows of no reason why any of these nominees will be unable to serve,
but in the event of any such unavailability, the proxies received will be voted
for such substitute nominee or nominees as the Board of Directors may recommend.
If the Reorganization is approved, the Directors of the Acquired Fund will cease
to serve as Directors of the Acquired Fund upon the dissolution of the Acquired
Fund pursuant to the Agreement.

    Committees and Board of Directors' Meetings. Each Fund has a standing Audit
Committee, which consists of the Directors who are not "interested persons" of
the Fund within the meaning of the 1940 Act. The principal purpose of the Audit
Committee is to review the scope of the annual audit conducted by the Fund's
independent auditors and the evaluation by such auditors of the accounting
procedures followed by the Fund. The members of the audit committee for both
Funds are Messrs. Grills, Mintz, Seiden, Woolf and Swensrud. The non-interested
Directors have retained independent legal counsel to assist them in connection
with these duties. Neither Fund has a nominating committee.
    
 
    During the fiscal year ended May 31, 1994, the Board of Directors of each
Fund held four meetings and the respective Audit Committee held four meetings.
Each of the Directors attended at least 75% of the total number of meetings of
the Board of Directors held while he was a Director during such period. All
members of the Audit Committee attended at least 75% of the meetings of the
Audit Committee held while he was a Director during such period.
 
   
    Interested Persons. The Fund considers Mr. Zeikel to be an "interested
person" of the Fund within the meaning of Section 2(a)(19) of the 1940 Act as a
result of the position he holds with FAM and its affiliates. Mr. Zeikel is the
President of both Funds and the President and a Director of FAM and MLAM.
    
 
   
    Compensation of Directors. FAM, the investment adviser, pays all
compensation of all officers and Directors of the Funds who are affiliated with
ML & Co. or its subsidiaries. Prior to January 19, 1994, the Acquiring Fund paid
each Director not affiliated with the investment adviser a fee of $2,500 per
year plus $500 per regular meeting attended, together with such Director's
actual out-of-pocket expenses relating to attendance at meetings. Also prior to
January 19, 1994, the Acquiring Fund paid each member of its Audit Committee a
fee of $250 per year plus $125 per meeting attended, together with such
Director's actual out-of-pocket expenses relating to attendance at meetings. As
of January 19, 1994, each Fund pays each Director not affiliated with the
investment adviser a fee of $2,600 per year, plus $250 per regular meeting
attended. The Funds also pay each member of its Audit Committee an annual fee of
$800 plus a fee of $150 for each Audit Committee meeting attended together with
such Director's actual out-pocket-expenses. For the fiscal period ended May 31,
1994, these fees and expenses aggregated $19,565 for the Acquiring Fund and
$18,960 for the Acquired Fund.

    Stock Ownership. At October 31, 1994, the Directors and officers of the
Funds as a group (thirteen persons) owned an aggregate of less than 1/4 of 1%
of the Common Stock of the Funds outstanding at such date. At such date,
Mr. Zeikel, a Director of the Funds, and the officers of the Funds owned an
aggregate of less than 1% of the outstanding shares of common stock of ML & Co.
    
 
    Section 30(f) of the 1940 Act and Section 16(a) of the Exchange Act require
the Funds' officers and Directors, investment adviser, affiliated persons of the
investment adviser and persons who own more than ten percent of a registered
class of either Fund's equity securities to file forms reporting their
affiliation with that Fund and reports of ownership and changes in ownership of
that Fund's Shares with
 
                                       34
<PAGE>
the Commission and the NYSE. These persons and entities are required by
Commission regulation to furnish each Fund with copies of all Section 16(a)
forms they file. Based on a review of these forms furnished to each Fund, both
of the Funds believe that for the period from each Fund's respective date of
organization through May 31, 1994, all Section 16(a) filing requirements
applicable to the Funds' officers and trustees, investment adviser and
affiliated persons of the investment adviser were complied with. To the
knowledge of each Fund, there are no greater than ten-percent stockholders of
either Fund.
 
                       SELECTION OF INDEPENDENT AUDITORS
 
   
    The Board of Directors of each Fund, including a majority of the Directors
who are not interested persons of the Funds, has selected the firm of Deloitte &
Touche LLP ("D&T"), Independent Auditors, to examine the financial statements of
each Fund for the current fiscal year. The Funds know of no direct or indirect
financial interest of D&T in each Fund. Such appointment is subject to
ratification or rejection by the stockholders of the Funds. Unless a contrary
specification is made, the accompanying proxy will be voted in favor of
ratifying the selection of such auditors.
    
 
   
    D&T also acts as independent auditors for ML & Co. and all of its
subsidiaries and for a majority of the investment companies for which FAM or
MLAM acts as investment adviser. The fees received by D&T from these other
entities are substantially greater, in the aggregate, than the total fees
received by it from the Fund. The Board of Directors of the Fund considered the
fact that D&T has been retained as the independent auditors for ML & Co. and the
other entities described above in its evaluation of the independence of D&T with
respect to the Funds.
    
 
    Representatives of D&T are expected to be present at the meeting and will
have the opportunity to make a statement if they so desire and to respond to
questions from stockholders.

* Commencement of operations
 
   
    During the period since the inception of the Funds, the Acquiring Fund's
Common Stock and the Acquired Fund's Common Stock have traded at premiums and
discounts to net asset value. Although there is no reason to believe that this
pattern should be affected by the Reorganization, it is not possible to state
whether shares of the Acquiring Fund will trade at a premium or discount to net
asset value following the Reorganization, or the extent of any such premium or
discount.
    
 
   
    On November 11, 1994, the closing sale prices of shares of the Acquiring
Fund and shares of the Acquired Fund were $10.375 and $10.125, respectively.
These prices represent a discount to net asset value of the Acquiring Fund of
16.5% and a discount to net asset value of the Acquired Fund of 17.7%.

                       INVESTMENT OBJECTIVE AND POLICIES
 
   
    Each Fund's investment objective is to provide its stockholders with high
current income exempt from Federal income taxes by investing primarily in a
portfolio of medium to lower grade or unrated municipal obligations the interest
on which, in the opinion of bond counsel to the issuer, is exempt from Federal
income taxes. Each Fund seeks to achieve its objective by investing at least 80%
of its assets, except during temporary defensive periods, in a portfolio of
obligations, issued by or on behalf of states, territories and possessions of
the United States and their political subdivisions, agencies or
instrumentalities paying interest which, in the opinion of bond counsel to the
issuer, is exempt from Federal income taxes ("Municipal Bonds"). While the
Acquiring Fund is not restricted as to the duration of Municipal Bonds it may
invest in, the Acquired Fund's investment objective restricts its investment in
Municipal Bonds to those that have remaining maturities of greater than one
year. Each Fund, at all times, except during temporary defensive periods,
maintains at least 65% of its assets in Municipal Bonds which are rated in any
one of the medium and lower rating categories of a nationally recognized
statistical rating organization or are unrated. For the Acquiring Fund, if such
Municipal Bonds are unrated, they will possess creditworthiness comparable, in
the opinion of the Investment Adviser, to securities rated in the medium and
lower categories. In the case of Moody's, S&P or Fitch, these ratings are
currently Baa (Moody's) or BBB (S&P or Fitch) or lower, respectively. These are
fundamental policies of each Fund and, therefore, may not be changed without a
vote of a majority of the outstanding shares of each Fund. Neither Fund
presently contemplates that it will invest more than 25% of its total assets
(taken at market value) in Municipal Bonds whose issuers are located in the same
state. However, the Acquired Fund may invest 25% or more of its total assets in
obligations of issuers in the health care industry. There can be no assurance
that the investment objective of each Fund will be realized.
    
 
   
    Investment in shares of the Acquiring Fund offers several benefits. The
Acquiring Fund offers investors the opportunity to receive income exempt from
Federal income taxes by investing in a professionally managed portfolio of
high-yielding Municipal Bonds. Since interest received on Municipal Bonds is
exempt from Federal income taxes, the yields on Municipal Bonds tend to compare
favorably with the net yield, after taxes, on many taxable debt securities.
Additionally, investment research and credit analysis relating to the municipal
securities in which the Acquiring Fund seeks to invest are not readily
available. Moreover, many of these securities are not widely traded and the
execution of transactions in such securities requires expertise. Consequently,
the professional portfolio management which is provided by the Investment
Adviser is particularly important in the sector of the municipal securities
market in which the Acquiring Fund invests. The Acquiring Fund also relieves the
investor of the burdensome administrative details involved in managing a
portfolio of Municipal Bonds. The benefits are at least partially offset by the
expenses involved in operating an investment company. Such expenses primarily
consist of the advisory and administrative fees and operational costs.
    
 
   
    Investments in lower rated or comparable unrated Municipal Bonds generally
provide a higher yield than higher rated tax-exempt securities of similar
maturity but are subject to greater market risk and are also subject to a
greater degree of risk with respect to the ability of the issuer to meet its
principal and interest obligations. See Appendix II to this Prospectus for a
description of Moody's, S&P's and Fitch's ratings of Municipal Bonds.
    
 
                                       41
<PAGE>
    Each Fund seeks to reduce risk through diversification, credit analysis and
monitoring of current developments and trends in both the economy and financial
markets. The Investment Adviser uses various means to research the stability
and/or potential for improvement of various municipal issuers in connection with
the purchase of their securities by each Fund. Evaluation of each Municipal Bond
may include the analysis of financial performance, debt structure, economic
factors and the administrative structure of the issuer. Additionally, the
priority of liens and the overall structure of the particular issue may be
factors which will determine suitability for purchase. Further investigation may
be performed and may include, among other things, discussions with project
management, corporate officers and industry experts, as well as site
inspections, area analysis, and project and financial projection analysis. All
purchases and sales also may be subject to the review of market data, economic
projections and the performance of the financial markets. Certain economic
indicators also may be monitored. Additionally, the Investment Adviser may vary
the average maturity of each Fund's portfolio securities, or may engage in
hedging transactions, based upon the Investment Adviser's assessment of economic
and market conditions.
 
   
    Each Fund is classified as non-diversified within the meaning of the 1940
Act, which means that each Fund is not limited by such Act in the proportion of
its assets that it may invest in securities of a single issuer. However, the
Funds' investments will be limited so as to qualify each Fund as a "regulated
investment company" for purposes of the Code. See "Taxes." To qualify, among
other requirements, each Fund will limit its investments so that, at the close
of each quarter of the taxable year, (i) not more than 25% of the market value
of its total assets will be 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 will be invested in the securities (other than U.S. Government
securities) of a single issuer and the Acquired Fund will not own more than 10%
of the outstanding voting securities of a single issuer. A fund which elects to
be classified as "diversified" under the 1940 Act must satisfy the foregoing 5%
requirement and 10% requirement with respect to 75% of its total assets. To the
extent that each Fund assumes large positions in the securities of a small
number of issuers, its net asset value may fluctuate to a greater extent than
that of a diversified company as a result of changes in the financial condition
or in the market's assessment of the issuers.
    
 
DESCRIPTION OF MUNICIPAL BONDS
 
    Municipal Bonds include primarily debt obligations, issued to obtain funds
for various public purposes, including construction and equipping of a wide
range of public facilities, refunding of outstanding obligations and obtaining
funds for general operating expenses and loans to other public or private
institutions for the construction of facilities. For the Acquired Fund, the
Municipal Bonds it invests in have remaining maturities of greater than one
year. In addition, certain types of industrial development bonds are issued by
or on behalf of public authorities to finance various privately operated
facilities and certain local facilities, including pollution control facilities.
For purposes of this 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.
 
                                       42
<PAGE>
    The two principal classifications of Municipal Bonds are "general
obligation" and "revenue" or "special obligation" bonds. General obligation
bonds are secured by the issuer's pledge of faith, credit and taxing power for
the payment of principal and interest. The taxing power of any governmental
entity may be limited, however, by provisions of state constitutions or laws,
and an entity's credit will depend on many factors, including potential erosion
of the tax base due to population declines, natural disasters, declines in the
state's industrial base or inability to attract new industries, economic limits
on the ability to tax without eroding the tax base, state legislative proposals
or voter initiatives to limit ad valorem real property taxes, and the extent to
which the entity relies on Federal or state aid, access to capital markets or
other factors beyond the state's or entity's control. 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 of a
special excise tax or other specific revenue source such as from the user of the
facility being financed. Industrial development bonds are, in most cases,
revenue bonds and generally are not secured by a 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.
 
    The Funds may purchase Municipal Bonds classified as "private activity
bonds" (in general, bonds that benefit non-governmental entities). Interest
received on certain tax-exempt securities which are classified as "private
activity bonds" may subject certain investors in the Fund to an alternative
minimum tax. There is no limitation on the percentage of the Fund's assets that
may be invested in Municipal Bonds which may subject certain investors to an
alternative minimum tax. See "Taxes."
 
    Federal tax legislation has limited the types and volume of bonds qualifying
for the Federal income tax exemption of interest. As a result, this legislation
and legislation which may be enacted in the future may affect the availability
of Municipal Bonds for investment by the Funds.
 
    Each Fund may invest a relatively high percentage of its assets in Municipal
Bonds issued by entities which may be located in the same geographic area, or
which may pay their interest obligations from the revenues derived from similar
projects such as hospitals, multifamily housing, nursing homes, continuing care
facilities, commercial facilities (including hotels), electric utility systems
or industrial companies. This may make the Funds more susceptible to similar
economic, political or regulatory occurrences. As the similarity in issuers
increases, the potential for fluctuation of the net asset value of shares of the
Funds also increases. Also, it is anticipated that a significant percentage of
the Municipal Bonds in each Fund's portfolio will be issued by entities or
secured by facilities with a relatively short operating history. Therefore,
investors should also be aware of the risks which these investments might
entail, as discussed below. See also "Industrial Development Bonds" below.
 
    Health Care Revenue Bonds. These securities include Municipal Bonds issued
to finance hospitals, nursing homes and continuing care facilities and which are
generally secured by the revenues of particular facilities. The ability of the
issuers of such securities to meet their obligations is dependent
 
                                       43
<PAGE>
upon, among other things, the revenues, costs and occupancy levels of the
subject facilities and the competitive nature of these industries. In addition,
a major portion of hospital and nursing home revenues typically is derived from
Federal or state programs such as Medicare and Medicaid and from various
insurers. Changes in the compensation and reimbursement formulae of these
governmental programs or in the rates paid by insurers may reduce revenues
available for the payment of principal of or interest on such bonds. New
governmental legislation or regulations and other factors, such as the inability
to obtain sufficient malpractice insurance, may also adversely affect the
revenues or costs of these issuers. Moreover, in the case of life care
facilities, since a portion of housing, medical care and other services may be
financed by an initial lump-sum deposit paid by occupants of the facility, there
may be risk if the facility does not maintain adequate financial resources to
secure estimated actuarial liabilities.
 
    A number of legislative proposals concerning health care have been
introduced in Congress in recent years or have been reported to be under
consideration. In addition, the Clinton administration has proposed a
comprehensive health care plan. These proposals include a wide range of topics,
including cost controls, national health insurance, incentives for competition
in the provision of health care services, tax incentives and penalties related
to health care insurance premiums, and promotion of prepaid health care plans.
The Funds are unable to predict the effect of any of these proposals, if
enacted.
 
    Single Family Housing Bonds and Multifamily Housing Bonds. Single family
housing bonds and multifamily housing bonds are obligations of state and local
housing authorities that have been issued in connection with a variety of single
and multifamily housing projects. Economic developments, including fluctuations
in interest rates, increasing construction and operating costs, increasing real
estate taxes and declining occupancy rates, and real estate investment risks may
have an adverse effect upon the revenues of such projects and such housing
authorities. Multifamily housing bonds may be subject to mandatory redemption
prior to maturity, including redemption from non-completion of the project or
upon receipt of FHA or certain other insurance proceeds. Bonds issued by state
or local units of authorities and payable from revenues from single family
residential mortgages may be subject to mandatory redemption prior to maturity,
including redemption from mortgage loan prepayments and undisbursed bond
proceeds reserved for the purpose of purchasing mortgage loans. Housing bonds
may also be subject to changes in creditworthiness due to potential weaknesses
of mortgage insurance companies providing various policies; fluctuations in the
valuation of invested funds and the strengths of banks and other entities which
may provide investment agreements; and smaller than expected mortgage portfolios
due to the inability to originate mortgages. To the extent the Funds invest in
housing bonds issued by an entity or entities located in the same geographic
area, the Funds may be subject to the risks associated with the general economy
of such area.
 
    Public Power Revenue Bonds. General problems of the electric utility
industry include difficulty in financing large construction programs during an
inflationary period; restrictions on operations and increased costs and delays
attributable to environmental considerations; the difficulty of the capital
markets in absorbing utility debt and equity securities; the availability of
fuel for electric generation at reasonable prices, including, among other
considerations, the potential rise in fuel costs and the costs associated with
conversion to alternate fuel sources; technical costs factors and other problems
 
                                       44
<PAGE>
associated with construction, licensing, regulation and operation of nuclear
facilities for electric generation, including, among other considerations, the
problems associated with the use of radioactive materials and the disposal of
radioactive waste; and the effects of energy conservation. Certain of the
issuers of these bonds may own or operate nuclear generating facilities.
Federal, state and municipal governmental authorities may from time to time
review and revise existing requirements and impose additional requirements
governing the licensing, construction and operation of nuclear power plants. In
addition, the licensing of certain nuclear power plants nearing completion of
construction or constructed has been delayed indefinitely by the refusal of
state and local officials to cooperate in emergency planning exercises that are
a prerequisite to licensing. Each of the problems referred to above could
adversely affect the ability of the issuer of public power revenue bonds to make
payments of principal and/or interest on such bonds. Certain municipal utilities
or agencies may have entered into contractual arrangements with investor-owned
utilities and large industrial users and consequently may be dependent in
varying degrees on the performance of such contracts for payment of bond debt
service. Also, the enforceability against municipalities of "take-and-pay" and
"take-or-pay" contracts which contracts secure bonds issued by other municipal
issuers has been successfully challenged in recent years.
 
    Transportation Revenue Bonds. Bonds in this category include bonds issued
for airport facilities, bridges, turnpikes, port facilities, railroad systems or
mass transit systems. Generally, airport facility revenue bonds are payable from
and secured by the revenues derived from the ownership and operation of a
particular airport. Payment on other transportation bonds is often dependent
primarily or solely on revenues from financed facilities, including user fees,
charges, tolls and rents. Such revenues may be adversely affected by increased
construction and maintenance costs or taxes, decreased use, competition from
alternative facilities, scarcity of fuel, reduction or loss of rents or the
impact of environmental considerations. Other transportation bonds may be
dependent primarily or solely on Federal, state or local assistance including
motor fuel and motor vehicle taxes, fees and licenses, and therefore may be
subject to fluctuations in such assistance.
 
    Water and Sewage Revenue Bonds. Bonds in this category include securities
issued to finance public water supply, treatment and distribution facilities,
and sewage collection, treatment and disposal facilities. Repayment of these
bonds is dependent primarily on revenues derived from the billing of
residential, commercial and industrial customers for water and sewer services,
as well as, in some instances, connection fees and hook-up charges. Such revenue
bonds may be adversely affected by the lack of availability of Federal and state
grants and by decisions of Federal and state regulatory bodies and courts.
 
    Solid Waste and Resource Recovery Revenue Bonds. Bonds in this category
include securities issued to finance facilities for removal and disposal of
solid waste. Repayment of these bonds is dependent on factors which may include
revenues from appropriations from a governmental entity, the financial condition
of the private project corporation* and revenues derived from the collection of
charges for disposal of solid waste. In addition, construction of such
facilities may be subject to cost overruns and the actual costs of operating
such facilities may exceed the costs anticipated at the time
 
- ------------
 
* For purposes of the description of users of facilities, all references to
  "corporations" are deemed to include any other nongovernmental person or
  entity.
 
                                       45
<PAGE>
the bonds were issued. Repayment of resource recovery bonds may also be
dependent to various degrees on revenues from the sale of electric energy or
steam. Bonds in this category may be subject to mandatory redemption in the
event of project noncompletion, if the project is rendered uneconomical, if the
project fails to meet certain performance criteria, or if it is considered an
environmental hazard.
 
    Pollution Control Facility Revenue Bonds. Bonds in the pollution control
facilities category include securities issued on behalf of private corporations
including utilities, to provide facilities for the treatment of air, water and
solid waste pollution. Repayment of these bonds is dependent upon income from
the specified pollution control facility and/or the financial condition of the
project corporation. In addition, governmental entities may from time to time
impose additional restrictions or regulations which could adversely affect the
cost or operation of the facility.
 
    Educational Facility Revenue Bonds. Educational facility revenue bonds
include debt of state and private colleges, universities and systems, and
parental and student loan obligations for dormitories, classrooms, libraries,
research and training facilities and student aid. The ability of universities
and colleges to meet their obligations is dependent on various factors,
including the revenues, costs and enrollment levels of the institutions. In
addition, their ability may be affected by declines in Federal, state and alumni
financial support, fluctuations in interest rates and construction costs,
increased maintenance and energy costs, failure or inability to raise tuition or
room charges and adverse results of endowment fund investments.
 
    Tax Increment Bonds. Tax increment bonds are issued to finance various
public improvements and redevelopment projects in blighted areas. Interest on
such bonds is payable from increases in real property taxes attributable to
increases in assessed value resulting from the redevelopment of the blighted
project area. Repayment risks include, among other things, a reduction in
taxable value in the project areas, reduction in tax rates, delinquencies in tax
payments or a general shortfall in forecasted tax revenues.
 
    Commercial Facility Revenue Bonds. The Funds may also invest in bonds for
other commercial facilities (including hotels) and industrial enterprises. The
viability of such facilities depends on, among other things, general economic
factors affecting those industries and affecting those geographic areas in which
such facilities are situated, as well as the ability of the individual
management of those facilities to maximize earnings and to remain competitive
within its service area.
 
    Industrial Development Bonds ("IDBs"). Each Fund reserves the right to
invest a portion of its assets in IDBs. IDBs are tax-exempt securities issued by
states, municipalities or public authorities and are issued to provide funds,
usually through a loan or lease arrangement, to a private corporation for the
purpose of financing construction or improvement of a facility to be used by the
corporation. Such bonds are secured primarily by revenues derived from loan
repayments or lease payments due from the corporation which may or may not be
guaranteed by a parent company or otherwise secured. In view of this, an
investor should be aware that repayment of such bonds depends on the revenues of
a private corporation and be aware of the risks that such an investment may
entail. Continued ability of a corporation to generate sufficient revenues for
the payment of principal and interest on such bonds will be affected by many
factors, including the size of the corporation, capital structure, demand for
 
                                       46
<PAGE>
products or services, competition, general economic conditions, government
regulation and the corporation's dependence for revenues on the operation of the
particular facility being financed.
 
    IDBs are often issued to provide funds for corporations from the industries
described above and, consequently, are subject to similar risks. IDBs are also
issued to provide funds to industrial companies. Investment in particular
industries may expose the Fund to risks associated with such industries.
 
    Lease Obligations. Also included within the general category of Municipal
Bonds are participation certificates issued by government authorities or
entities to finance the acquisition or construction of equipment, land and/or
facilities. The certificates represent participations in a lease, an installment
purchase contract or a conditional sales contract (hereinafter collectively
called "lease obligations") relating to such equipment, land or facilities.
Although lease obligations do not constitute general obligations of the issuer
for which the issuer's unlimited taxing power is pledged, a lease obligation is
frequently backed by the issuer's covenant to budget for, appropriate and make
the payments due under the lease obligation. However, certain lease obligations
contain "non-appropriation" clauses which provide that the issuer has no
obligation to make lease or installment purchase payments in future years unless
money is appropriated for such purpose on a yearly basis. Although
"non-appropriation" lease obligations are secured by the leased property,
disposition of the property in the event of foreclosure might prove difficult.
These securities represent a relatively new type of financing that has not yet
developed the depth of marketability associated with more conventional
securities.
 
   
    Non-Municipal Tax-Exempt Securities. Each Fund may also invest in securities
not issued by or on behalf of a state or territory or by an agency or
instrumentality thereof, if it nevertheless believes such securities to be
exempt from Federal income taxation ("Non-Municipal Tax-Exempt Securities").
Non-Municipal Tax-Exempt Securities could include trust certificates or other
instruments evidencing interests in one or more long-term municipal securities.
Non-Municipal Tax-Exempt Securities also may include securities issued by other
investment companies that invest in Municipal Bonds, to the extent such
investments are permitted by the 1940 Act.
    
 
OTHER INVESTMENT POLICIES
 
   
    Each Fund has the authority to invest as much as 35% of its assets in
Municipal Bonds in the higher rating categories of nationally recognized
statistical rating organizations (ratings of A or higher by Moody's, S&P or
Fitch or in comparable unrated securities). In addition, each Fund reserves the
right to temporarily invest more than 20% of its assets in short-term municipal
securities, or short-term taxable money market securities (including commercial
paper, certificates of deposit and repurchase agreements) for defensive purposes
when, in the opinion of the Investment Adviser, prevailing market or financial
conditions warrant. Taxable commercial paper must be rated A-1 or A-2 by S&P,
Prime-1 or Prime-2 by Moody's, F-1+ or F-1 by Fitch or have credit
characteristics equivalent to such ratings in the opinion of the Investment
Adviser. The short-term tax-exempt municipal obligations will also be in the
highest rating categories as determined either by Moody's (currently, MIG1 and
MIG2 for notes and P-1 for commercial paper), S&P (currently, SP-1 and SP-2 for
notes and A-1 for commercial paper), or Fitch (currently, F-1 and F-2 for notes
and F-1 for commercial paper), except that each Fund
    
 
                                       47
<PAGE>
may invest in lower rated or unrated short-term tax-exempt obligations to the
extent that such investments do not exceed 20% of its assets. Certificates of
deposit must be issued by depository institutions with total assets of at least
$1 billion, except that the Funds may invest in certificates of deposit of
smaller institutions if such certificates of deposit are Federally insured.
 
    When-Issued Securities and Delayed Delivery Transactions. The Funds may
purchase or sell Municipal Bonds on a delayed basis or when-issued basis at
fixed purchase or sale terms. These transactions arise when securities are
purchased or sold by the Funds with payment and delivery taking place in the
future. The purchase will be recorded on the date a Fund enters into the
commitment and the value of the obligation will thereafter be reflected in the
calculation of its net asset value. The value of the obligation on the delivery
day may be more or less than its purchase price. A separate account of each Fund
will be established with its custodian consisting of cash, cash equivalents or
liquid high grade Municipal Bonds having a market value at all times at least
equal to the amount of the forward commitment.
 
    Indexed and Inverse Floating Obligations. The Funds may invest in Municipal
Bonds the return on which is based on a particular index of value or interest
rates. For example, each Fund may invest in Municipal Bonds that pay interest
based on an index of Municipal Bond interest rates or based on the value of gold
or some other product. The principal amount payable upon maturity of certain
Municipal Bonds also may be based on the value of an index. To the extent each
Fund invests in Municipal Bonds of these sorts, its return on such Municipal
Bonds will be subject to risk with respect to the value of the particular index.
Also, the Funds may invest in so-called "inverse floating obligations" or
"residual interest bonds" on which the interest rates typically vary inversely
with a short-term floating rate (which may be reset periodically by a dutch
auction, a remarketing agent, or by reference to a short-term tax-exempt
interest rate index). The Funds may purchase original issue inverse floating
rate bonds in both the primary and secondary markets and may also purchase in
the secondary market synthetically created inverse floating rate bonds evidenced
by custodial or trust receipts. Generally, interest rates on inverse floating
rate bonds will decrease when short-term rates increase, and will increase when
short-term rates decrease. Such securities have the effect of providing a degree
of investment leverage, since they may increase or decrease in value in response
to changes, as an illustration, in market interest rates at a rate which is a
multiple (typically two) of the rate at which fixed-rate long-term tax-exempt
securities increase or decrease in response to such changes. As a result, the
market values of such securities will generally be more volatile than the market
values of fixed-rate tax-exempt securities. To seek to limit the volatility of
these securities, the Funds may purchase inverse floating obligations with
shorter term maturities or which contain limitations on the extent to which the
interest rate may vary. The Investment Adviser believes that indexed and inverse
floating obligations represent a flexible portfolio management instrument for
the Funds which allows the Investment Adviser to vary the degree of investment
leverage relatively efficiently under different market conditions.
 
    Call Rights. The Funds may purchase a Municipal Bond issuer's right to call
all or a portion of such Municipal Bond for mandatory tender for purchase (a
"Call Right"). A holder of a Call Right may exercise such right to require a
mandatory tender for the purchase of related Municipal Bonds, subject to certain
conditions. A Call Right that is not exercised during the maturity of the
related
 
                                       48
<PAGE>
Municipal Bond will expire without value. The economic effect of holding both a
Call Right and the related Municipal Bond is identical to holding a Municipal
Bond as a non-callable security.
 
OPTIONS AND FUTURES TRANSACTIONS
 
    Each Fund may hedge all or a portion of its portfolio investments against
fluctuations in interest rates through the use of certain financial futures
contracts ("financial futures contracts") and options thereon. While the Funds'
use of hedging strategies is intended to reduce the volatility of the net asset
value of shares of the Funds' Common Stock, the net asset value of such shares
will fluctuate. There can be no assurance that a Fund's hedging transactions
will be effective. Furthermore, the Funds only engage in hedging activities when
movements in interest rates occur from time to time and not necessarily when
movements in interest rates occur.
 
    Certain Federal income tax requirements may limit the Funds' ability to
engage in hedging transactions. Gains from transactions in options and futures
contracts distributed to stockholders will be taxable as ordinary income or, in
certain circumstances, as long-term capital gains to stockholders. See
"Taxes--Tax Treatment of Options and Futures Transactions."
 
    The following is a description of the transactions involving financial
futures contracts or options thereon in which the Funds may engage, limitations
on the use of such transactions and risks associated therewith. The investment
policies with respect to the hedging transactions of each Fund are not
fundamental policies and may be modified by the Board of Directors of each Fund
without the approval of its stockholders.
 
    Writing Covered Call Options. Each Fund may write (i.e., sell) covered call
options with respect to Municipal Bonds it owns, thereby giving the holder of
the option the right to buy the underlying security covered by the option from
it at the stated exercise price until the option expires. Each Fund writes only
covered options, which means that so long as it is obligated as the writer of a
call option, it will own the underlying securities subject to the option. The
Funds may not write covered call options on underlying securities in an amount
exceeding 15% of the market value of their total assets.
 
    The Funds will receive a premium from writing a call option, which increases
their return on the underlying security in the event the option expires
unexercised or is closed out at profit. By writing a call, each Fund limits its
opportunity to profit from an increase in the market value of the underlying
security above the exercise price of the option for as long as its obligation as
a writer continues. Covered call options serve as a partial hedge against a
decline in the price of the underlying security. Each Fund may engage in closing
transactions in order to terminate outstanding options that it has written.
 
    Purchase of Options. The Funds may purchase put options in connection with
its hedging activities. By buying a put the Fund has a right to sell the
underlying security at the exercise price, thus limiting the Fund's risk of loss
through a decline in the market value of the security until the put expires. The
amount of any appreciation in the value of the underlying security will be
partially offset by the amount of the premium paid for the put option and any
related transaction costs. Prior to its expiration,
 
                                       49
<PAGE>
a put option may be terminated by entering into a closing sale transaction;
profit or loss from the sale will depend on whether the amount received is more
or less than the premium paid for the put option plus the related transaction
costs. A closing sale transaction cancels out the Fund's position as the
purchaser of an option by means of an offsetting sale of an identical option
prior to the expiration of the option it has purchased. In certain
circumstances, the Fund may purchase call options on securities held in its
portfolio on which it has written call options, or on securities which it
intends to purchase. The Fund will not purchase options on securities if, as a
result of such purchase, the aggregate cost of all outstanding options on
securities held by the Fund would exceed 5% of the market value of the Fund's
total assets.
 
    Financial Futures Contracts and Options Thereon. The Fund is authorized to
purchase and sell certain financial futures contracts and options thereon solely
for the purpose of hedging its investments in Municipal Bonds against declines
in value and to hedge against increases in the cost of securities it intends to
purchase. A financial futures contract obligates the seller of a contract to
deliver and the purchaser of a contract to take delivery of the type of
financial instrument covered by the contract, or, in the case of index-based
futures contracts, to make and accept a cash settlement, at a specific future
time for a specified price. A sale of financial futures contracts may provide a
hedge against a decline in the value of portfolio securities because such
depreciation may be offset, in whole or in part, by an increase in the value of
the position in the financial futures contracts. A purchase of financial futures
contracts may provide a hedge against an increase in the cost of securities
intended to be purchased, because such appreciation may be offset, in whole or
in part, by an increase in the value of the position in the financial futures
contracts or options thereon. Distributions, if any, of net long-term capital
gains from certain transactions in futures or options are taxable at long-term
capital gains rates for Federal income tax purposes, regardless of the length of
time the stockholder has owned the Fund shares. See "Taxes."
 
    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 the
broker 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 futures contract fluctuates making the long and short positions in the
futures contract more or less valuable.
 
    The Funds 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 recently issued tax-exempt bonds, and purchase and sell put and call
options on such futures contracts for the purpose of hedging Municipal Bonds
which each Fund holds or anticipates purchasing against adverse changes in
interest rates. The Funds also may purchase and sell financial futures contracts
on U.S. Government securities and purchase and sell put and call options on such
futures contracts for such hedging purposes. 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.
 
                                       50
<PAGE>
    Subject to policies adopted by its Board of Directors, each Fund may also
engage in transactions in other financial futures contracts and options thereon,
such as financial futures contracts or options on other municipal bond indices
which may become available, if the Investment Adviser should determine that
there is normally sufficient correlation between the prices of such futures
contracts and the Municipal Bonds in which it invests to make such hedging
appropriate.
 
    Over-the-Counter Options. The Funds may engage in options and futures
transactions on exchanges and in over-the-counter markets. In general,
exchange-traded contracts are third-party contracts (i.e., performance of the
parties' obligations is guaranteed by an exchange or clearing corporation) with
standardized strike prices and expiration dates. Over-the-counter options ("OTC
Options") transactions are two-party contracts with price and terms negotiated
by the buyer and seller. See "Restrictions on OTC Options" below for information
as to restrictions on the use of OTC Options.
 
    Restrictions on OTC Options. The Funds engage in OTC options only with
member banks of the Federal Reserve System and primary dealers in U.S.
Government securities or with affiliates of such banks or dealers which have
capital of at least $50 million or whose obligations are guaranteed by an entity
having capital of at least $50 million. OTC options and assets used to cover OTC
options written by the Funds are considered by the staff of the Securities and
Exchange Commission to be illiquid. The illiquidity of such options or assets
may prevent a successful sale of such options or assets, result in a delay of a
sale, or reduce the amount of proceeds that might otherwise be realized.
 
    Risk Factors in Options and Futures Transactions. Utilization of financial
futures transactions and options thereon involve the risk of imperfect
correlation in movements in the price of financial futures contracts or options
thereon and movements in the price of the security which 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,
the Fund will experience a gain or loss which will not be completely offset by
movements in the price of such security. There is a risk of imperfect
correlation where the securities underlying financial futures contracts have
different maturities, ratings, 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 which serves as a basis for a financial
futures contract or option thereon. Finally, in the case of 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 or options and Municipal Bonds may
be adversely affected by economic, political, legislative or other developments
which have a disparate impact on the respective markets for such securities.
 
    Under regulations of the Commodity Futures Trading Commission ("CFTC"), the
futures trading activities described herein will not result in the Funds being
deemed a "commodity pool," as defined under such regulations, provided that each
Fund adheres to certain restrictions. In particular, each Fund may (1) purchase
and sell financial futures contracts and options thereon solely for bona fide
hedging purposes, as defined under CFTC regulations, and, in addition (2)
purchase or sell any other financial futures contracts or options if,
immediately thereafter, the sum of the amount of initial margin deposit on its
existing futures position and premiums paid for outstanding options, if any, not
entered for
 
                                       51
<PAGE>
hedging purposes would not exceed 5% of the market value of its net assets.
Margin deposits may consist of cash or securities acceptable to the broker and
the relevant contract market.
 
    When each 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
short-term, high-grade, fixed-income securities in a segregated account with its
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
futures contract, thereby ensuring that the use of such futures contract is
unleveraged.
 
    Although certain risks are involved in financial futures contracts and
options thereon the Investment Adviser believes that, because the Funds engage
in options and futures transactions only for hedging purposes, the options and
futures portfolio strategies of the Funds do not subject the Funds to certain
risks frequently associated with speculation in financial futures contracts and
options thereon. The Funds must meet certain Federal income tax requirements
under the Code in order to qualify for the special tax treatment afforded
regulated investment companies, including a requirement that less than 30% of
its gross income in each taxable year be derived from the sale or other
disposition of securities held for less than three months. See "Taxes--Tax
Treatment of Options and Futures Transactions."
 
    The volume of trading on 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.
 
    The Funds intend to enter into options and financial futures transactions,
on an exchange or in the over-the-counter market, only if there appears to be a
liquid secondary market for such options or futures. 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 transaction or the related
option. The inability to close financial futures positions or the related option
also could have an adverse impact on a Fund's ability to effectively hedge its
portfolio. There is also the risk of loss by each Fund of margin deposits or
collateral in the event of bankruptcy of a broker with which it has an open
position in an option or futures contract.
 
    The liquidity of a secondary market in a financial futures contract or
option thereon may be adversely affected by "daily price fluctuations limits"
established by commodity exchanges which limit the amount of fluctuation in a
financial futures contract or option price during a single trading day. Once the
daily limit has been reached in the contract or option, no trades may be entered
into at a price beyond the limit, thus preventing the liquidation of open
financial futures positions or related options. Prices have in the past moved
beyond the daily limit on a number of consecutive trading days.
 
    If it is not possible to close a financial futures position or related
option entered into by a Fund, the Fund would be required to make daily cash
payments of variation margin in the event of adverse price movements. In such a
situation, if the Fund has insufficient cash, it may have to sell portfolio
securities to meet daily variation margin requirements at a time when it may be
disadvantageous to do so.
 
                                       52
<PAGE>
    The successful use of these transactions also depends on the ability of the
Investment Adviser to forecast correctly the direction and extent of interest
rate movements within a given time frame. To the extent these rates remain
stable during the period in which a financial futures contract is held by a Fund
or moves in a direction opposite to that anticipated, the Fund may realize a
loss on the hedging transaction which is not fully or partially offset by an
increase in the value of portfolio securities. As a result, its total return for
such period may be less than if it had not engaged in the hedging transaction.
 
                            INVESTMENT RESTRICTIONS
 
    The following are fundamental investment restrictions of each Fund and may
not be changed without the approval of the holders of a majority of each Fund's
outstanding voting securities (which, for this purpose and under the 1940 Act,
means the lesser of (i) 67% of the shares represented at a meeting at which more
than 50% of the outstanding shares are represented or (ii) more than 50% of the
outstanding shares).
 
                                       53
<PAGE>
    Neither Fund may:
 
        1. Make investments for the purpose of exercising control or management.
 
        2. Purchase securities of other investment companies, except in
    connection with a merger, consolidation, acquisition or reorganization, or
    by purchase in the open market of securities of closed-end investment
    companies and only if immediately thereafter not more than 10% of the Fund's
    total assets would be invested in such securities.
 
        3. Purchase or sell real estate, real estate limited partnerships,
    commodities or commodity contracts; provided that the Fund may invest in
    securities secured by real estate or interests therein or issued by
    companies that invest in real estate or interests therein and the Fund may
    purchase and sell financial futures contracts and options thereon.
 
        4. Issue senior securities or borrow amounts in excess of 5% of its
    total assets taken at market value.
 
        5. Underwrite securities of other issuers except insofar as the Fund may
    be deemed an underwriter under the Securities Act of 1933 in selling
    portfolio securities.
 
        6. Make loans to other persons, except that the Fund may purchase
    Municipal Bonds and other debt securities and enter into repurchase
    agreements in accordance with its investment objective, policies and
    limitations.
 
        7. Invest more than 25% of its total assets (taken at market value at
    the time of each investment) in securities of issuers in a single industry
    except that the Fund will invest 25% or more of its assets in Municipal
    Bonds issued to finance projects in the health care industry. (For purposes
    of this restriction, states, municipalities and their political subdivisions
    are not considered to be part of any industry.)
 
   
    Additional investment restrictions adopted by each Fund, which may be
changed by its Board of Directors, provided that each Fund may not:
    
 
        1. Invest more than 25% of its total assets (taken at market value at
    the time of each investment) in the Municipal Bonds of any one state.
 
        2. Mortgage, pledge, hypothecate or in any manner transfer, as security
    for indebtedness, any securities owned or held by the Fund except as may be
    necessary in connection with borrowings mentioned in (4) above or except as
    may be necessary in connection with transactions in financial futures
    contracts and options thereon.
 
        3. Purchase any securities on margin, except that the Fund may obtain
    such short-term credit as may be necessary for the clearance of purchases
    and sales of portfolio securities (the deposit or payment by the Fund of
    initial or variation margin in connection with financial futures contracts
    and options thereon is not considered the purchase of a security on margin).
 
        4. Make short sales of securities or maintain a short position or invest
    in put, call, straddle or spread options except that the Fund may write,
    purchase and sell options and futures on Municipal Bonds, U.S. Government
    obligations and related indices or otherwise in connection with bona fide
 
                                       54
<PAGE>
    hedging activities and may purchase and sell Call Rights to require a
    mandatory tender for the purchase of related Municipal Bonds.
 
    If a percentage restriction on investment policies or the investment on use
of assets set forth above is adhered to at the time a transaction is effected,
later changes in percentages resulting from changing values will not be
considered a violation.
 
   
    The Investment Adviser and Merrill Lynch share a common parent, ML & Co.
Because of the affiliation of Merrill Lynch with the Funds, the Funds are
prohibited from engaging in certain transactions involving Merrill Lynch except
pursuant to an exemptive order of the Securities and Exchange Commission or
otherwise in compliance with the provisions of the 1940 Act and the rules and
regulations thereunder. Included among such restricted transactions will be
purchases from or sales to Merrill Lynch of securities in transactions in which
it acts as principal. An exemptive order has been obtained which permits the
Funds to effect principal transactions with Merrill Lynch in high quality,
short-term, tax-exempt securities subject to conditions set forth in such order.
See "Portfolio Transactions."
    
 
                                       55
<PAGE>
                             DIRECTORS AND OFFICERS
 
    The Acquiring Fund and the Acquired Fund have the same six Directors, five
of whom are not "interested persons," as defined in the 1940 Act, of either
Fund. The Directors are responsible for the overall supervision of the
operations of the Funds and perform various duties imposed on the directors of
investment companies by the 1940 Act and under applicable Maryland law. The
Acquiring Fund and the Acquired Fund also have the same executive officers. For
further information regarding the Directors and officers of each Fund, see
"Election of Directors."
 
                INVESTMENT ADVISORY AND MANAGEMENT ARRANGEMENTS
 
   
    The Investment Adviser (the general partner of which is Princeton Services,
a wholly-owned subsidiary of ML&Co.), is an affiliate of MLAM and is owned and
controlled by ML&Co. The Investment Adviser provides the Acquiring Fund and the
Acquired Fund with investment advisory, management and administrative services.
The Investment Adviser, or MLAM, acts as the investment adviser for over 100
other registered investment companies. The Investment Adviser also offers
portfolio management and portfolio analysis services to individuals and
institutions. As of October 31, 1994, the Investment Adviser and MLAM had a
total of approximately $167.6 billion in investment company and other
portfolio assets under management, including accounts of certain affiliates of
the Investment Adviser. The principal business address of the Investment Adviser
is 800 Scudders Mill Road, Plainsboro, New Jersey 08536.
    
 
    The Investment Advisory Agreements between the Investment Adviser and each
of the Funds (the "Investment Advisory Agreements") provide that, subject to the
direction of the Board of Directors of each Fund, the Investment Adviser is
responsible for the actual management of each Fund's portfolio. The
responsibility for making decisions to buy, sell or hold a particular security
rests with the Investment Adviser, subject to review by the Board of Directors.
 
    The Investment Adviser provides the portfolio management for the Acquiring
Fund and the Acquired Fund. Such portfolio management considers analyses from
various sources (including brokerage firms with which each Fund does business),
makes the necessary investment decisions, and places orders for transactions
accordingly. The Investment Adviser also is responsible for the performance of
certain administrative and management services for each of the Funds.
 
   
    For the services provided by the Investment Adviser under the Investment
Advisory Agreements, each Fund currently pays a monthly fee at an annual rate of
0.55% of its average weekly net assets (i.e., the average weekly value of its
total assets, minus the sum of its accrued liabilities). For purposes of this
calculation, average weekly net assets is determined at the end of each month on
the basis of the average net assets of each Fund for each week during the month.
The assets for each weekly period are determined by averaging the net assets at
the last business day of a week with the net assets at the last business day of
the prior week.
    
 
    The Investment Advisory Agreements obligate the Investment Adviser to
provide investment advisory services and to pay all compensation of and furnish
office space for officers and employees of the Acquiring Fund and the Acquired
Fund connected with investment and economic research, trading
 
                                       56
<PAGE>
   
and investment management of each Fund, as well as the compensation of all
Directors of each Fund who are affiliated persons of the Investment Adviser or
any of its affiliates. Each Fund pays all other expenses incurred in its
operation, including, among other things, expenses for legal and auditing
services, taxes, costs of printing proxies, listing fees, stock certificates and
stockholder reports, charges of the Custodian and the Transfer Agent, Dividend
Disbursing Agent and Registrar, expenses of portfolio transactions, fees and
expenses with respect to any issuance of preferred stock or any borrowing,
Securities and Exchange Commission fees, fees and expenses of unaffiliated
Directors, accounting and pricing costs (including the weekly calculation of the
net asset value), insurance, interest, brokerage costs, litigation and other
extraordinary or non-recurring expenses, mailing and other expenses properly
payable by each Fund. Accounting services will be provided to each Fund by the
Investment Adviser, and each Fund will reimburse the Investment Adviser for its
costs in connection with such services.
    
 
    Unless earlier terminated as described below, the Investment Advisory
Agreements with the Acquiring Fund and the Acquired Fund will remain in effect
until June 18, 1995 and July 31, 1995, respectively, and from year to year
thereafter if approved annually (a) by each Fund's Board of Directors or by a
majority of the outstanding shares of each Fund and (b) by a majority of the
Directors who are not parties to such contract or interested persons (as defined
in the 1940 Act) of any such party. Such contract is not assignable and may be
terminated without penalty on 60 days' written notice at the option of either
party thereto or by the vote of the stockholders of each Fund.
 
                             PORTFOLIO TRANSACTIONS
 
    Subject to policies established by each Fund's Board of Directors, the
Investment Adviser is primarily responsible for the execution of each Fund's
portfolio transactions. In executing such transactions, the Investment Adviser
seeks to obtain the best results for each Fund, 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 the
Investment Adviser generally seeks reasonably competitive commission rates, the
Funds do not necessarily pay the lowest commission or spread available.
 
   
    The Funds have no obligation to deal with any broker or dealer in execution
of transactions in portfolio securities. Subject to obtaining the best price and
execution, securities firms which provided supplemental investment research to
the Investment Adviser, including Merrill Lynch, may receive orders for
transactions by the Funds. Information so received will be in addition to and
not in lieu of the services required to be performed by the Investment Adviser
under the Investment Advisory Agreements and the expenses of the Investment
Adviser will not necessarily be reduced as a result of the receipt of such
supplemental information.
    
 
    The securities in which the Funds primarily invest are traded in the
over-the-counter markets, and the Funds 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 1940 Act, except as
permitted by exemptive order, persons affiliated with either Fund are prohibited
from dealing with that Fund as principal in the purchase and sale of securities.
Since transactions in the over-the-counter
 
                                       57
<PAGE>
market usually involve transactions with dealers acting as principal for their
own account, the Funds do not deal with affiliated persons, including Merrill
Lynch and its affiliates, in connection with such transactions except that,
pursuant to an exemptive order from the Securities and Exchange Commission
obtained by the Investment Adviser, the Funds may engage in principal
transactions with Merrill Lynch in high quality, short-term, tax-exempt
securities. See "Investment Restrictions." Affiliated persons of either Fund may
serve as its broker in over-the-counter transactions conducted on an agency
basis.
 
   
    No brokerage commissions were paid by the Acquiring Fund for the period from
commencement of investment operations on June 25, 1993 to May 31, 1994.
    
 
    The Funds may also purchase securities from tax-exempt issuers in
individually negotiated transactions with the issuer. Because an active trading
market may not exist for such securities, the price that the Funds may pay for
these securities or receive on their resale may be lower than that for similar
securities with a more liquid market.
 
PORTFOLIO TURNOVER
 
    Generally, the Funds do not purchase securities for short-term trading
profits. However, the Funds may dispose of securities without regard to the time
they have been held when such action, for defensive or other reasons, appears
advisable to the Investment Adviser. Each Fund's annual portfolio turnover
rate, under normal circumstances is less than 100%. The portfolio turnover rate
is calculated by dividing the lesser of purchases or sales of portfolio
securities for the particular fiscal year by the monthly average of the value of
the portfolio securities owned by each of the Funds 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.
 
                          DIVIDENDS AND DISTRIBUTIONS
 
    The Acquiring Fund and the Acquired Fund intend to distribute substantially
all of their net investment income. Dividends from such net investment income
are declared and paid monthly. All net realized long- or short-term capital
gains, if any, are distributed to each Fund's stockholders at least annually.
 
    See "Automatic Dividend Reinvestment Plan" for information concerning the
manner in which dividends and distributions may be automatically reinvested in
shares of Common Stock of each Fund. Dividends and distributions may be taxable
to stockholders under certain circumstances as discussed below, whether they are
reinvested in shares of each Fund or received in cash.
 
                                       58
<PAGE>
                                     TAXES
 
GENERAL
 
   
    The Funds qualify for the special tax treatment afforded regulated
investment companies ("RICs") under the Internal Revenue Code of 1986, as
amended (the "Code"). So qualifying, in any taxable year in which it distributes
at least 90% of its taxable net income and 90% of its tax-exempt net income (see
below), each Fund is not subject to Federal income tax to the extent that it
distributes its net investment income and realized capital gains. The Funds
currently distribute substantially all of such income.
    
 
   
    The Funds 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
its 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(a) of the Code (relating generally to obligations of a state or
local governmental unit), each Fund shall be qualified to pay exempt-interest
dividends to its stockholders. Exempt-interest dividends are dividends or any
part thereof (other than a capital gain dividend) paid by a Fund which are
attributable to interest on tax-exempt obligations and designated by the Fund as
exempt-interest dividends in a written notice mailed to the Fund's stockholders
within 60 days after the close of its taxable year. In general, exempt-interest
dividends may be treated by stockholders for all purposes as items of interest
excludable from their gross income under Code Section 103(a). 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 the Fund during the taxable year. Stockholders are advised to
consult their tax adviser, however, with respect to whether exempt-interest
dividends retain the exclusion under Code Section 103(a) if such stockholders
would be treated as "substantial users" or "related persons" under Code Section
147(a) with respect to some or all of the tax-exempt obligations held by the
Funds. The Code provides that interest on indebtedness used to purchase or carry
shares of the Funds is not deductible to the extent attributable to
exempt-interest dividends. Since the Funds will not invest in the stock of
domestic corporations, stockholders will not be entitled to the dividends
received deduction for corporations. At present, the highest marginal Federal
income tax rate for individuals is 39.6%.
    
 
   
    The Funds may realize capital gains, which will constitute taxable income.
To the extent that the Funds' distributions are derived from interest on its
taxable investments or from an excess of net short-term capital gains over net
long-term capital losses, such distributions will be considered ordinary income
for Federal income tax purposes.  In order to avoid taxation on its
net long-term capital gains, the Funds may elect to distribute "capital gain
dividends" to its stockholders. Distributions, if any, of net long-term capital
gains from the sale of securities or from certain transactions in futures or
options designated as capital gain dividends in a written notice mailed to
stockholders not later than 60 days after the close of the taxable year are
taxable at long-term capital gains rates for Federal income tax purposes,
regardless of the length of time the stockholder has owned Fund shares. For
Federal income tax purposes, any loss upon the sale or exchange of Fund shares
held for six months or less will be treated as long-term capital loss to the
extent of any long-term capital gains distributions received by the stockholder.
In addition, such loss will be disallowed to the extent of any exempt-interest
dividends received by the stockholder. If
    
 
                                       59
<PAGE>
Fund pays a dividend in January which was declared in the previous October,
November or December to stockholders of record on a specified date in one of
such months, then such dividend or distribution will be treated for tax purposes
as being paid by that Fund and received by its stockholders on December 31 of
the year in which the dividend was declared.
 
    The Code requires a RIC to pay a nondeductible 4% excise tax to the extent
the RIC does not distribute 98% of its investment company taxable income, with
certain adjustments, determined on a calendar year basis, and 98% of its capital
gains, determined in general on an October 31 year end, plus certain
undistributed amounts from previous years. The required distributions, however,
are based only on the taxable income of a RIC. The excise tax, therefore, will
generally not apply to the tax-exempt income of RICs such as the Funds that pay
exempt-interest dividends. The Funds anticipate that they will make sufficient
timely distributions of taxable income so as to avoid imposition of the excise
tax.
 
   
    The Code subjects interest received on certain otherwise tax-exempt
securities to an alternative minimum tax. The alternative minimum tax will apply
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 government units and which
benefit non-governmental entities, (e.g., bonds used for industrial development
or housing purposes). Income received on such bonds is classified as an item of
tax preference which could subject investors in such bonds, including
stockholders of the Funds, to an alternative minimum tax. However, an individual
stockholder filing a joint return who does not have any tax preference items
subject to the alternative minimum tax other than income received from the Funds
derived from private activity bonds would have to receive more than $40,000 of
such income before becoming subject to the alternative minimum tax. The Funds
intend to purchase such "private activity bonds" and will report to stockholders
within 60 days after its taxable year-end the portion of the Funds' 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 reflects a corporation's economic income). Because
an exempt-interest dividend paid by the Funds will be included in adjusted
current earnings, whether or not such dividend is attributable to private
activity bonds, a corporate stockholder may be required to pay an alternative
minimum tax on exempt-interest dividends paid by the Fund.
 
    In addition, the Code imposes a deductible tax (the "Environmental Tax") on
a corporation's alternative minimum taxable income (computed without regard to
the alternative tax net operating loss deduction or the environmental tax
deduction) at a rate of $12 per $10,000 (0.12%) of alternative minimum taxable
income in excess of $2,000,000. The Environmental Tax will be imposed for
taxable years beginning after December 31, 1986 and before January 1, 1996. The
Environmental Tax will be imposed even if the corporation is not required to pay
an alternative minimum tax, because the corporation's regular income tax
liability exceeds its minimum tax liability. The Code provides, however, that
RICs, such as the Funds, are not subject to the Environmental Tax. However,
exempt-interest dividends paid by the Funds that increase alternative minimum
taxable income for corporate stockholders (as described above) will be included
in the Environmental Tax calculation.

    The value of shares acquired pursuant to the Funds' dividend reinvestment
plan will generally be excluded from gross income to the extent that the cash
amount reinvested would be excluded from gross income. If, when the Funds'
shares are trading at a premium over net asset value, the Funds issue shares
pursuant to the dividend reinvestment plan which have a greater fair market
value than the amount of cash reinvested, it is possible that all or a portion
of such discount (which may not exceed 5% of the fair market value of the Fund's
shares) could be viewed as a taxable distribution. If the discount is viewed as
a taxable distribution, it is also possible that the taxable character of this
discount would be allocable to all the stockholders, including stockholders who
do not participate in the dividend reinvestment plan. Thus, stockholders who do
not participate in the dividend reinvestment plan might be required to report as
ordinary income a portion of their distributions equal to their allocable share
of the discount.
 
    Under certain Code provisions, some taxpayers may be subject to a 31%
withholding tax on reportable dividends, capital gains distributions and
redemption payments ("backup withholding"). Backup withholding is not required
with respect to dividends representing "exempt interest." Generally, taxpayers
subject to backup withholding will be those for whom a taxpayer identification
number is not on file with the Funds or who, to the Funds' knowledge, have
furnished an incorrect number. When establishing an account, an investor must
certify under penalty of perjury that such number is correct and that such
investor is not subject to backup withholding.
 
    Distributions of ordinary income and short-term capital gains to
stockholders who are non-resident aliens will be subject to a 30% United States
withholding tax under existing provisions of the Code applicable to foreign
individuals and entities, unless a reduced rate of withholding or a withholding
exemption is provided under applicable treaty law. Non-resident stockholders are
urged to consult their own tax advisers concerning the applicability of the
United States withholding tax.
 
TAX TREATMENT OF OPTIONS AND FUTURES TRANSACTIONS
 
    The Funds may write, purchase or sell municipal bond index futures contracts
and interest rate futures contracts on U.S. Government securities ("financial
futures contracts"). The Funds may also purchase and write call and put options
on such financial futures contracts. Unless the Funds are eligible to make and
makes a special election, such options and futures contracts that are "Section
1256 contracts" will be "marked to market" for Federal income tax purposes at
the end of each taxable year, i.e., each option or futures contract will be
treated as sold for its fair market value on the last day of the taxable year.
In general, unless the special election referred to in the previous sentence is
made, gain or loss from transactions in options and futures contracts will be
60% long-term and 40% short-term capital gain or loss.
 
    Code Section 1092, which applies to certain "straddles", may affect the
taxation of the Funds' transactions in options and futures contracts. Under
Section 1092, the Funds may be required to postpone recognition for tax purposes
of losses incurred in certain closing transactions in options and futures.
 
    One of the requirements for qualification as RICs is that less than 30% of
the Funds' gross income may be derived from gains from the sale or other
disposition of securities held for less than three months. Accordingly, the
Funds may be restricted in effecting closing transactions within three months
 
                                       61

after entering into an option for futures contract. Proposed legislation, if
enacted in its current form, would eliminate this requirement.
    
 
STATE AND LOCAL TAXES
 
    The exemption from Federal income tax for exempt-interest dividends does not
necessarily result in an exemption for such dividends under the income or other
tax laws of any state or local taxing authority. Stockholders are advised to
consult their own tax advisers concerning state and local tax matters.
 
    Depending upon the extent of the Funds' activities in those states and
localities in which its offices are maintained or in which its agents are
located, the Funds may be subject to the tax laws of such states or localities.

    The foregoing is a general and abbreviated summary of the applicable
provisions of the Code and Treasury Regulations presently in effect. For the
complete provisions, reference should be made to the pertinent Code sections and
the Treasury Regulations promulgated thereunder. The Code and these Treasury
Regulations are subject to change by legislative or administrative action either
prospectively or retroactively.
 
   
    Stockholders are urged to consult their tax advisers regarding specific
questions as to Federal, foreign, state or local taxes.

                                NET ASSET VALUE
 
    Net asset value per share of Common Stock of the Acquiring Fund and the
Acquired Fund is determined at 4:15 P.M., New York time, on the last business
day in each week. For purposes of determining the net asset value of a share of
Common Stock, the value of the securities held by the Funds plus any cash or
other assets (including interest and dividends accumulated but not yet received)
minus all liabilities (including accrued expenses) is divided by the total
number of shares of Common Stock outstanding at such time. Expenses, including
the fees payable to the Investment Adviser, are accrued daily.
 
    The Municipal Bonds in which the Funds invest are traded primarily in the
over-the-counter markets. In determining net asset value, the Funds utilize the
valuations of portfolio securities furnished by a pricing service approved by
the Board of Directors. The pricing service typically values portfolio
securities at the bid price or the yield equivalent when quotations are readily
available. Municipal Bonds for which quotations are not readily available are
valued at fair market value on a consistent basis as determined by the pricing
service using a matrix system to determine valuations. The procedures of the
pricing service and its valuations are reviewed by the officers of each Fund
under the general supervision of the Board of Directors. The Board of Directors
of each Fund has determined in good faith that the use of a pricing service is a
fair method of determining the valuation of portfolio securities. Bonds with
remaining maturities of 60 days or less are valued at amortized cost, unless
this method no longer produces fair valuations. Positions in futures contracts
are valued at closing prices for such contracts established by the exchange on
which they are traded, or if market quotations are not readily available, are
valued at fair value on a consistent basis using methods determined in good
faith by the Board of Directors of each Fund.
 
    The Funds determine and make available for publication the net asset value
of their Common Stock weekly. Currently, the net asset values of shares of
publicly traded closed-end investment companies investing in debt securities are
published in Barron's, the Monday edition of The Wall Street Journal and the
Monday edition of The New York Times.
 
                          DESCRIPTION OF CAPITAL STOCK
 
    The Funds are each authorized to issue 200,000,000 shares of capital stock,
par value $.10 per share, all of which shares are initially classified as Common
Stock. Each Fund's Board of Directors is authorized, however, to classify or
reclassify any unissued shares of capital stock by setting or changing the
preferences, conversion or other rights, voting powers, restrictions,
limitations as to dividends, qualifications or terms or conditions of
redemption.
 
    Shares of Common Stock, when issued and outstanding, will be fully paid and
non-assessable. Stockholders are entitled to share pro rata in the net assets of
each Fund available for distribution to stockholders upon liquidation of a Fund.
Stockholders are entitled to one vote for each share held.
 
    Each Fund will send unaudited reports at least semi-annually and audited
financial statements to all of its stockholders.

CERTAIN PROVISIONS OF THE ARTICLES OF INCORPORATION
 
    Each Fund's Articles of Incorporation include identical provisions that
could have the effect of limiting the ability of other entities or persons to
acquire control of each Fund or to change the composition of its Board of
Directors and could have the effect of depriving stockholders of an opportunity
to sell their shares at a premium over prevailing market prices by discouraging
a third party from seeking to obtain control of the Fund. For a description of
these provisions of the Acquiring Fund, which are identical to those of the
Acquired Fund, see "The Reorganization--Certain Provisions in the Acquiring
Fund's Articles of Incorporation."
 
    Reference should be made to the Funds' Articles of Incorporation on file
with the Securities and Exchange Commission for the full text of these
provisions.

            TRANSFER AGENT, DIVIDEND DISBURSING AGENT AND REGISTRAR

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors and Shareholders,
  MUNIASSETS FUND, INC.:
 
   
We have audited the accompanying statement of assets, liabilities, and capital
including the schedule of investments, of MuniAssets Fund, Inc. as of May 31,
1994, the related statements of operations and changes in net assets, and the
financial highlights for the period June 25, 1993 (commencement of operations)
to May 31, 1994. These financial statements and the financial highlights are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and the financial highlights based on our
audits.
    
 
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and the financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned at May 31,
1994 by correspondence with the custodian and brokers. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
In our opinion, such financial statements and financial highlights present
fairly, in all material respects, the financial position of MuniAssets Fund,
Inc. as of May 31, 1994, the results of its operations, the changes in its net
assets, and the financial highlights for the period June 25, 1993 to May 31,
1994 in conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
    
 
   
1. SIGNIFICANT ACCOUNTING POLICIES:
    
 
   
    MuniAssets Fund, Inc. (the "Fund") is registered under the Investment
Company Act of 1940 as a newly organized, non-diversified, closed-end management
investment company. Prior to commencement of operations on June 25, 1993, the
Fund had no operations other than those relating to organizational matters and
the sale of 7,055 shares of Common Stock on June 11, 1993 to Fund Asset
Management, L.P. ("FAM") for $100,005. The Fund determines and makes available
for publication the net asset value of its Common Stock on a weekly basis. The
Fund's Common Stock is listed on the New York Stock Exchange under the symbol
MUA. The following is a summary of significant accounting policies followed by
the Fund.
    
 
   
    (a) Valuation of investments--Municipal bonds are traded primarily in the
over-the-counter markets and are valued at the last available bid price in the
over-the-counter market or on the basis of yield equivalents as obtained by the
Fund's pricing service from one or more dealers that make markets in the
securities. Financial futures contracts, which are traded on exchanges, are
valued at their closing prices as of the close of such exchanges. Options, which
are traded on exchanges, are valued at their last sale price as of the close of
such exchanges or, lacking any sales, at the last available bid price. Short-
term investments with a remaining maturity of sixty days or less are valued at
amortized cost, which approximates market value. Securities and assets for which
market quotations are not readily available are valued at fair value as
determined in good faith by or under the direction of the Board of Directors of
the Fund.
    
 
   
    (b) Financial futures contracts--The Fund may purchase or sell interest rate
futures contracts. Upon entering into a contract, the Fund deposits and
maintains as collateral such initial margin as required by the exchange on which
the transaction is effected. Pursuant to the contract, the Fund agrees to
receive from or pay to the broker an amount of cash equal to the daily
fluctuation in value of the contract. Such receipts or payments are known as
variation margin and are recorded by the Fund as unrealized gains or losses.
When the contract is closed, the Fund records a realized gain or loss equal to
the difference between the value of the contract at the time it was opened and
the value at the time it was closed.
    
 
   
    (c) Income taxes--It is the Fund's policy to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no Federal income tax provision is required.
    
 
   
    (d) Security transactions and investment income--Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Interest income is recognized on the accrual basis. Original issue discounts
and market premiums are amortized into interest income. Realized gains and
losses on security transactions are determined on the identified cost basis.
    
 
                                      F-6
<PAGE>
   
    (e) Deferred organization and offering expenses--Deferred organization
expenses are charged to expense on a straight-line basis over a five-year
period, beginning with the commencement of operations of the Fund. Direct
expenses relating to the public offering of the Fund's shares of Common Stock
were charged to capital at the time of issuance of the shares.
    
 
   
    (f) Dividends and distributions--Dividends from net investment income are
declared and paid monthly. Distributions of capital gains are recorded on the
ex-dividend dates.
    
 
   
    (g) Non-income producing investments--Written and purchased options are
non-income producing investments.
    
 
   
INVESTMENT ADVISORY AGREEMENT AND TRANSACTIONS WITH AFFILIATES:
    
 
   
    The Fund has entered into an Investment Advisory Agreement with FAM.
Effective January 1, 1994, the investment advisory business of FAM was
reorganized from a corporation to a limited partnership. Both prior to and after
the reorganization, ultimate control of FAM was vested with Merrill Lynch & Co.,
Inc. ("ML & Co."). The general partner of FAM is Princeton Services, Inc.
("PSI"), an indirect wholly-owned subsidiary of ML & Co. The limited partners
are ML & Co. and Fund Asset Management, Inc. ("FAMI"), which is also an
indirect wholly-owned subsidiary of ML & Co.
    
 
   
    FAM is responsible for the management of the Fund's portfolio and provides
the necessary personnel, facilities, equipment and certain other services
necessary to the operations of the Fund. For such services, the Fund pays a
monthly fee of 0.55% based upon the average weekly value of the Fund's net
assets. For the period June 25, 1993 to May 31, 1994, FAM earned fees of
$351,471, of which $330,746 was voluntarily waived. In addition, FAM
voluntarily reimbursed the Fund $84,644 in additional expenses.
    
 
   
    Financial Data Services, Inc. ("FDS"), an indirect wholly-owned subsidiary
of ML & Co., is the Fund's transfer agent.
    
 
   
    Accounting services are provided to the Fund by FAM at cost.
    
 
   
    Certain officers and/or directors of the Fund are officers and/or directors
of FAM, FAMI, FDS, PSI, Merrill Lynch, Pierce, Fenner & Smith Inc. ("MLPF&S"),
and/or ML & Co.

highlights are the responsibility of the Fund's management. Our responsibility
is to express an opinion on these financial statements and the financial

Those standards require that we plan and perform the audit to obtain reasonable

well as evaluating the overall financial statement presentation. We believe that
our audit provides a reasonable basis for our opinion.
 
   
In our opinion, such financial statements and financial highlights present

matters and the sale of 7,055 shares of Common Stock on October 15, 1993 to Fund
Asset Management, L.P. ("FAM") for $100,005. The Fund determines and makes
available for publication the net asset value of its Common Stock on a weekly
basis. The Fund's Common Stock is listed on the New York Stock Exchange under
the symbol MBD. The following is a summary of significant accounting policies
followed by the Fund.
    
 
   
    (a) Valuation of investments--Municipal bonds and other portfolio securities
in which the Fund invests are traded primarily in the over-the-counter markets
and are valued at the last available bid price in the over-the-counter market or
on the basis of yield equivalents as obtained by the Fund's pricing service from
one or more dealers that make markets in the securities. Financial futures
contracts, which are traded on exchanges, are valued at their last sale price as
of the close of such exchanges. Options on futures contracts on US Government
securities, which are traded on exchanges, are valued at their last bid price in
the case of options purchased and their last asked price in the case of options
written. Short-term investments with a remaining maturity of sixty days or less
are valued at amortized cost, which approximates market value. Securities and
assets for which market quotations are not readily available are valued at fair
value as determined in good faith by or under the direction of the Board of
Directors of the Fund.
    
 
   
    (b) Financial futures contracts--The Fund may purchase or sell interest rate
futures contracts and options on such futures contracts for the purpose of
hedging the market risk on existing securities or the intended purchase of
securities. Futures contracts are contracts for delayed delivery of securities
at a specific future date and at a specific price or yield. Upon entering into a
contract, the Fund deposits and maintains as collateral such initial margin as
required by the exchange on which the transaction is effected. Pursuant to the
contract, the Fund agrees to receive from or pay to the broker an amount of cash
equal to the daily fluctuation in value of the contract. Such receipts or
payments are known as variation margin and are recorded by the Fund as
unrealized gains or losses. When the contract is closed, the Fund records a
realized gain or loss equal to the difference between the value of the contract
at the time it was opened and the value at the time it was closed.
    
 
   
    (c) Income taxes--It is the Fund's policy to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no Federal income tax provision is required.
    
 
   
    (d) Security transactions and investment income--Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Interest income is recognized on the accrual basis. Original issue discounts
and market premiums are amortized into interest income. Realized gains and
losses on security transactions are determined on the identified cost basis.

<PAGE>
   
    (e) Deferred organization and offering expenses--Deferred organization
expenses are charged to expense on a straight-line basis over a five-year period
beginning with the commencement of operations of the Fund. Direct expenses
relating to the public offering of the Fund's shares of Common Stock were
charged to capital at the time of issuance of the shares.
    
 
   
    (f) Dividends and distributions--Dividends from net investment income are
declared and paid monthly. Distributions of capital gains are recorded on the
ex-dividend dates.
    
 
   
    (g) Non-income producing investments--Written and purchased options are
non-income producing investments.

the reorganization, ultimate control of FAM was vested with Merrill Lynch & Co.,
Inc. ("ML & Co."). The general partner of FAM is Princeton Services, Inc.

the necessary personnel, facilities, equipment and certain other services
necessary to the operations of the Fund. For such services, the Fund pays a
monthly fee of 0.55% based upon the average daily value of the Fund's net
assets. From October 29, 1993 to May 31, 1994, FAM earned fees of $298,995, all
of which was voluntarily waived. In addition, FAM voluntarily elected to
reimburse the Fund $118,940 in additional expenses.
    
 
   
    Accounting services are provided to the Fund by FAM at cost.
    
 
   
    Certain officers and/or directors of the Fund are officers and/or directors

1. SIGNIFICANT ACCOUNTING POLICIES:
    
 
   
    MuniBond Income Fund, Inc. and MuniAssets Fund, Inc. (collectively, the
"Funds") are registered under the Investment Company Act of 1940 as
non-diversified, closed-end management investment companies. The Funds determine
and make available for publication the net asset value of their Common Stock on
a weekly basis. The Common Stock of MuniBond Income and MuniAssets are listed on
the New York Stock Exchange under the symbols MBD and MUA, respectively. The
following is a summary of significant accounting policies followed by the Funds.
    
 
   
    (a) Valuation of investments--Municipal bonds and other portfolio securities
in which the Funds invest are traded primarily in the over-the-counter markets
and are valued at the last available bid price in the over-the-counter markets
or yield equivalent as obtained by the Funds' pricing service from dealers that
make markets in such securities. Financial futures contracts, which are traded
on exchanges, are valued at their closing prices as of the close of such
exchanges. Options, which are traded on exchanges, are valued at their last sale
price as of the close of such exchanges or, lacking any sales, at the last
available bid price. Securities with remaining maturities for sixty days or less
are valued at amortized cost which approximate market value. Securities and
assets for which market quotations are not readily available are valued at their
fair value as determined in good faith by or under the direction of the Boards
of Directors of the Funds.
    
 
   
    (b) Financial futures contracts--The Funds 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 a specific price or yield. Upon entering into a
contract, the Funds deposit and maintain as collateral such initial margin as
required by the exchange on which the transaction is effected. Pursuant to the
contract, the Funds agree to receive from or pay to the broker an amount of
cash equal to the daily fluctuation in value of the contract. Such receipts or
payments are known as variation margin and are recorded by the Funds as
unrealized gains or losses. When the contract is closed, the Funds record a
realized gain or loss equal to the difference between the value of the contract
at the time it was opened and the value at the time it was closed.
    
 
   
    (c) Income taxes--It is the policy of the Funds to comply with the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute substantially all of their taxable income to their
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 and offering expenses--Deferred organization
expenses are charged to expense on a straight-line basis over a five-year period
beginning with the commencement of operations of each Fund. Direct expenses
relating to the public offering of the Funds' shares of Common Stock were
    
 
                                      F-18

charged at the time of issuance of the shares. The deferred organization
expenses of MuniBond Income Fund, Inc. were written off as part of the
adjustments included in the Funds' combined statement of assets, liabilities and
capital.

declared and paid monthly. Distributions of capital gains are recorded on the

                          INDEPENDENT AUDITORS' REPORT
 
   
FUND ASSET MANAGEMENT, INC.:
    
 
   
We have audited the accompanying consolidated balance sheet of Fund Asset
Management, Inc. and subsidiary (the "Company") as of December 31, 1993. This
balance sheet is the responsibility of the Company's management. Our
responsibility is to express an opinion on the balance sheet based on our audit.
    
 
We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the balance sheet is free of material misstatement. An
audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the balance sheet. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall balance sheet presentation. We believe that our audit
provides a reasonable basis for our opinion.
 
   
In our opinion, such consolidated balance sheet presents fairly, in all material
respects, the financial position of the Company at December 31, 1993 in
conformity with generally accepted accounting principles.

ORGANIZATION

    Fund Asset Management, Inc. and subsidiary (the "Company"), a wholly-owned
subsidiary of Merrill Lynch Investment Management, Inc. (the "Parent" or
"MLIM"), which is an indirect wholly-owned subsidiary of Merrill Lynch & Co.,
Inc. ("ML & Co."), serves as an investment adviser to various registered 
open-end investment companies. The Company is also a lessor participant in 
certain leveraged and sales-type lease agreements.
    
 
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
   
    Income Taxes--The results of the operations of the Company are included in
the consolidated Federal and combined state and local income tax returns filed
by ML & Co. It is the policy of ML & Co. to allocate the tax associated with
such operating results to each respective subsidiary in a manner which
approximates the separate company method. In 1992, ML & Co. adopted Statement of
Financial Accounting Standards No. 109, "Accounting for Income Taxes" ("SFAS
109") which requires an asset and liability method in recording income taxes on
all transactions that have been recognized in the financial statements. SFAS 109
provides that deferred taxes be adjusted to reflect tax rates at which future
tax liabilities or assets are expected to be settled or realized.
    
 
TRANSACTIONS WITH AFFILIATES
 
    The Company serves as an investment adviser for certain affiliated
investment companies. The Company maintains investments in certain of these
investment companies. Such investments are carried at the lower of cost or
market value. Market value is determined based upon quoted market prices.
 
    The Company has an arrangement with Merrill Lynch, Pierce, Fenner & Smith
Incorporated ("MLPF&S") an affiliate, which provides that the Company, which
receives revenue as investment adviser to certain investment companies (the
"Funds"), reimburse MLPF&S for certain costs incurred in processing
transactions involving shares of the Funds.

   
    ML & Co. is the holder of the company's excess cash, which is available on
demand to meet current liabilities.  ML & Co. credits the Company for interest
at a floating rate approximating ML & Co.'s average borrowing rate, based on
the Company's average daily balances to/from ML & Co.
    

    The "Receivable from affiliated companies" arising from lease transactions
is summarized as follows:
 
Monies advanced to fund lease transactions.................   $(103,476,954)
Tax benefits allocated to the Company by ML & Co...........      88,699,254
Other......................................................      39,279,223

    The Company has a 49 percent limited partnership interest in ML Plainsboro
Limited Partnership ("MLP") whose general partner is an affiliate. Profits and
losses are allocated to the Company based on its percentage interest.

stockholder's equity.
    
 
INVESTMENTS IN LEASES

    Financing beyond the Company's equity interest in the purchase price of the
properties was furnished by outside parties in the form of long-term debt that
provides for no recourse against the Company and is secured by a first lien on
the properties and related rentals. At the end of the respective lease terms,
ownership of the properties remains with the Company.
 
   
    The Company's net investment in leveraged leases is summarized as follows:

INVESTMENTS IN LEASES--(CONTINUED)
    The Company's investment in the sales-type leases consisted of the following
elements at December 31, 1993.
 
Minimum lease payments receivable..............................   $3,672,000

    At December 31, 1993 minimum lease payments receivable are $3,672,000 for
1994.
 
    For Federal income tax purposes, the Company receives the investment tax
credit and has the benefit of tax deductions for (i) depreciation on the entire
amount of leased assets and (ii) interest on the outstanding long-term debt. For
state and local tax purposes, the Company also receives the benefits of tax
deductions from (i) and (ii) above. Since, during the early years of the leases,
those deductions exceed the Company's lease rental income, substantial excess
deductions are available to be applied against the Company's other income and
the consolidated income of ML & Co. In the later years of these leases, rental
income will exceed the related deductions and taxes will be payable (to the
extent that net deductions arising from additional leveraged lease transactions
do not offset such net lease income). Deferred taxes have been provided to
reflect these temporary differences.
 
INCOME TAXES
 
    As part of the consolidated group, the Company transfers its current Federal
and state tax liabilities to MLIM. No such amounts were due to MLIM at December
31, 1993.
 
PENSION PLAN
 
    The Company participates in the ML & Co. Comprehensive Retirement Program
(the "Program") consisting of the Retirement Accumulation Plan ("RAP") and the
Employee Stock Ownership Plan (the "ESOP"). Under the program, cash
contributions made by the Company and the ML & Co. stock held by the ESOP will
be allocated quarterly to participants' accounts. Allocations will be based on
years of service, age and eligible compensation. Actuarial data regarding the
Company's Plan participants is not separately available.

investment advisory assets in exchange for its 1% general partnership interest.
The partnership's profits and losses are to be allocated in proportion to the
capital contributions of the partners.

                                   APPENDIX I
    
 
                      AGREEMENT AND PLAN OF REORGANIZATION
 
    THIS AGREEMENT AND PLAN OF REORGANIZATION (this "Agreement") is made as of
the 17th day of November, 1994, by and between MuniBond Income Fund, Inc., a
Maryland corporation ("MuniBond"), and MuniAssets Fund, Inc., a Maryland
corporation ("MuniAssets").
 
                             PLAN OF REORGANIZATION
 
    The reorganization will comprise the acquisition by MuniAssets of
substantially all of the assets, and the assumption of all of the liabilities,
of MuniBond in exchange solely for an equal aggregate value of MuniAssets's
shares of common stock, with a par value of $0.10 per share ("MuniAssets Common
Stock"), and the subsequent distribution to MuniBond stockholders in liquidation
of MuniBond of all of the MuniAssets Common Stock received in exchange for their
corresponding shares of common stock of MuniBond, with a par value of $0.10 per
share ("MuniBond Common Stock"), upon and subject to the terms hereinafter set
forth (the "Reorganization").
 
    In the course of the Reorganization, MuniAssets Common Stock will be
distributed to MuniBond stockholders as follows: each holder of MuniBond Common
Stock will be entitled to receive the number of shares of MuniAssets Common
Stock to be received by MuniBond equal to the aggregate net asset value of the
MuniBond Common Stock owned by such stockholder on the Exchange Date (as defined
in Section 7 of this Agreement). In consideration therefor, on the Exchange Date
MuniAssets shall assume all of MuniBond's obligations and liabilities then
existing, whether absolute, accrued, contingent or otherwise. It is intended
that the Reorganization described in this Plan shall be a reorganization within
the meaning of Section 368(a) (l) (D) of the Internal Revenue Code of 1986, as
amended (the "Code"), and any successor provision.
 
    As promptly as practicable after the liquidation of MuniBond pursuant to the
Reorganization, MuniBond shall be dissolved in accordance with the laws of the
State of Maryland and will terminate its registration under the Investment
Company Act of 1940, as amended (the "1940 Act").
 
                                   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, MuniBond and MuniAssets hereby agree as follows:
 
    1. Representations and Warranties of MuniBond. MuniBond represents and
warrants to, and agrees with, MuniAssets that:
 
        (a) MuniBond is a corporation duly organized, validly existing and in
    good standing in conformity with the laws of the State of Maryland, and has
    the power to own all of its assets and to
 
                                      I-1
<PAGE>
    carry out this Agreement. MuniBond 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) MuniBond is duly registered under the 1940 Act as a non-diversified,
    closed-end management investment company (File No. 811-07081), and such
    registration has not been revoked or rescinded and is in full force and
    effect. MuniBond has elected to qualify and has qualified as a regulated
    investment company under Sections 851-855 of the Code as of its taxable year
    ended May 31, 1994, has been a regulated investment company at all times
    since its inception and meets the requirements for and intends to continue
    to qualify as a regulated investment company for its taxable year ending
    upon the liquidation of MuniBond.
 
        (c) As used in this Agreement, the term "Investments" shall mean (i) the
    investments of MuniBond shown on the schedule of its investments as of the
    Valuation Time (as defined in Section 3(c) of this Agreement) furnished to
    MuniAssets, with such additions thereto and deletions therefrom as may have
    arisen in the course of MuniBond's business up to the Valuation Time; and
    (ii) all other assets owned by MuniBond or liabilities incurred as of the
    Valuation Time, except that MuniBond 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 dividends 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 Directors of MuniBond reasonably
    shall deem to exist against the Fund, if any, at the Valuation Time, for
    which contingent and other appropriate liability reserves shall be
    established on MuniBond's books. MuniBond 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 so retained by MuniBond shall be disbursed by MuniBond pro
    rata to its stockholders upon dissolution of the Fund as a final liquidating
    dividend.
 
        (d) MuniBond 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 Directors, 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) MuniAssets has been furnished with a statement of assets,
    liabilities and capital and a schedule of investments of MuniBond, each as
    of May 31, 1994, said financial statements having been audited by Deloitte &
    Touche LLP, independent public accountants. An unaudited statement of
    assets, liabilities and capital of MuniBond and an unaudited schedule of
    investments of MuniBond, each as of the Valuation Time, will be furnished to
    MuniAssets at or prior to the Exchange Date for the purpose of determining
    the number of shares of MuniAssets Common Stock to be issued pursuant to
    Section 4 of this Agreement; and each will fairly present the financial
    position of MuniBond as of the Valuation Time in conformity with generally
    accepted accounting principles applied on a consistent basis.
    
 
                                      I-2
<PAGE>
 
        (f) MuniAssets has been furnished with (i) the prospectus of MuniBond,
    dated October 22, 1993, relating to the MuniBond Common Stock (the "MuniBond
    Common Stock Prospectus") and said prospectus does not contain any untrue
    statement of a material 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.
 
        (g) There are no material legal, administrative or other proceedings
    pending or, to the knowledge of MuniBond, threatened against MuniBond which
    assert liability on the part of MuniBond or which materially affect its
    financial condition or its ability to consummate the Reorganization.
    MuniBond is not charged with or, to the best of its knowledge, 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.
 
        (h) There are no material contracts outstanding to which MuniBond 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
    MuniAssets prior to the Valuation Time.
 
        (i) MuniBond is not a party to or obligated under any provision of its
    Articles of Incorporation, 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.
 
        (j) MuniBond has no known liabilities of a material amount, contingent
    or otherwise, other than those shown on its statements of assets,
    liabilities and capital referred to above, those incurred in the ordinary
    course of its business as an investment company since May 31, 1994 and those
    incurred in connection with the Reorganization. As of the Valuation Time,
    MuniBond will advise MuniAssets 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.
 
        (k) MuniBond has filed, or has obtained extensions to file, all Federal,
    state and local tax returns which are required to be filed by it, and has
    paid or has obtained extensions to pay, all Federal, state and local taxes
    shown on said returns to be due and owing and all assessments received by
    it, up to and including the taxable year in which the Exchange Date occurs.
    All tax liabilities of MuniBond have adequately been provided for on its
    books, and no tax deficiency or liability of MuniBond has been asserted and
    no question with respect thereto has been raised by the Internal Revenue
    Service or by any state or local tax authority for taxes in excess of those
    already paid, up to and including the taxable year in which the Exchange
    Date occurs.
 
        (l) At both the Valuation Time and the Exchange Date, MuniBond will have
    full right, power and authority to sell, assign, transfer and deliver the
    Investments. At the Exchange Date, subject only to the delivery of the
    Investments as contemplated by this Agreement, MuniBond will
 
                                      I-3
<PAGE>
    have good and marketable title to all of the Investments, and MuniAssets
    will acquire all of the Investments free and clear of any encumbrances,
    liens or security interests and without any restrictions upon the transfer
    thereof (except those imposed by the Federal or state securities laws and
    those imperfections of title or encumbrances as do not materially detract
    from the value or use of the Investments or materially affect title
    thereto).
 
        (m) No registration under the Securities Act of 1933, as amended (the
    "1933 Act"), of any of the Investments would be required if they were, as of
    the time of such transfer, the subject of a public distribution by
    MuniAssets.
 
        (n) No consent, approval, authorization or order of any court or
    governmental authority is required for the consummation by MuniBond of the
    Reorganization, except such as may be required under the 1933 Act, the
    Securities Exchange Act of 1934, as amended (the "1934 Act"), and the 1940
    Act or state securities laws (which term as used herein shall include the
    laws of the District of Columbia and Puerto Rico).
 
        (o) The registration statement filed by MuniAssets on Form N-14 relating
    to the MuniAssets
    Common Stock to be issued pursuant to this Agreement, and any supplement or
    amendment thereto or to the documents therein (as amended, the "N-14
    Registration Statement"), on the effective date of the N-14 Registration
    Statement, at the time of the stockholders' meetings referred to in Section
    6(a) of this Agreement and on the Exchange Date, insofar as it relates to
    MuniBond (i) complied or will comply in all material respects with the
    provisions of the 1933 Act, the 1934 Act and the 1940 Act and the rules and
    regulations thereunder, and (ii) did not or will not contain any untrue
    statement of a material fact or omit to state any material fact required to
    be stated therein or necessary to make the statements therein not
    misleading; and the prospectus and statement of additional information
    included therein did not or will not contain any untrue statement of a
    material 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; provided, however, that the representations and
    warranties in this subsection shall apply only to statements in or omissions
    from the N-14 Registration Statement made in reliance upon and in conformity
    with information furnished by MuniBond for use in the N-14 Registration
    Statement as provided in Section 7 of this Agreement.
 
        (p) MuniBond is authorized to issue 200,000,000 shares of capital stock,
    par value $0.10 per share, each outstanding share of which is fully paid,
    nonassessable and has full voting rights.
 
        (q) All of the issued and outstanding shares of MuniBond Common Stock
    were offered for sale and sold in conformity with all applicable Federal and
    state securities laws.
 
        (r) The books and records of MuniBond made available to MuniAssets

    effects of bankruptcy, insolvency, moratorium, fraudulent conveyance and
    similar laws relating to or affecting creditors' rights generally and court
    decisions with respect thereto.
 
        (f) There are no material legal, administrative or other proceedings
    pending or, to the knowledge of MuniAssets, threatened against MuniAssets
    which assert liability on the part of MuniAssets or which materially affect
    its financial condition or its ability to consummate the Reorganization.
    MuniAssets is not charged with or, to the best of its knowledge, threatened

    administrative ruling relating to any aspect of its business.
 
        (g) MuniAssets is not a party to or obligated under any provision of its
    Articles of Incorporation, 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

        (h) There are no material contracts outstanding to which MuniAssets is a
    party that have not been disclosed in the N-14 Registration Statement or
    will not otherwise be disclosed to MuniBond prior to the Valuation Time.
 
        (i) MuniAssets has no known liabilities of a material amount, contingent
    or otherwise, other than those shown on MuniAssets's statements of assets,
    liabilities and capital referred to above, those incurred in the ordinary
    course of its business as an investment company since May 31, 1994 and those
    incurred in connection with the Reorganization. As of the Valuation Time,
    MuniAssets will advise MuniBond 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.
 
        (j) No consent, approval, authorization or order of any court or
    governmental authority is required for the consummation by MuniAssets of the
    Reorganization, except such as may be required under the 1933 Act, the 1934
    Act, the 1940 Act or state securities laws.
 
        (k) The N-14 Registration Statement, on its effective date, at the time
    of the stockholders' meetings referred to in Section 6(a) of this Agreement
    and at the Exchange Date, insofar as it relates to MuniAssets (i) complied
    or will comply in all material respects with the provisions of the 1933 Act,
    the 1934 Act and the 1940 Act and the rules and regulations thereunder and
    (ii) did not or will not contain any untrue statement of a material fact or

    use in the N-14 Registration Statement as provided in Section 7 of this
    Agreement.
 
        (l) MuniAssets is authorized to issue 200,000,000 shares of capital

    paid, nonassessable and has full voting rights.
 
        (m) The MuniAssets Common Stock to be issued to MuniBond pursuant to
    this Agreement will have been duly authorized and, when issued and delivered
    pursuant to this Agreement, will be legally and validly issued and will be
    fully paid and nonassessable and will have full voting rights, and no
    stockholder of MuniAssets will have any preemptive right of subscription or
    purchase in respect thereof.
 
        (n) At or prior to the Exchange Date, the MuniAssets Common Stock to be
    transferred to MuniBond on the Exchange Date will be duly qualified for
    offering to the public in all states of the United States in which the sale
    of shares of MuniAssets presently are qualified, and there are a sufficient
    number of such shares registered under the 1933 Act and with each pertinent
    state securities commission to permit the transfers contemplated by this
    Agreement to be consummated.

    3. The Reorganization. (a) Subject to the requisite approvals of the
stockholders of each of MuniBond and MuniAssets being given, and to the other
terms and conditions contained herein, MuniBond agrees to convey, transfer and
deliver to MuniAssets for the benefit of MuniAssets, and MuniAssets agrees to
acquire from MuniBond for the benefit of MuniAssets, on the Exchange Date all of
the Investments (including interest accrued as of the Valuation Time on debt
instruments) of MuniBond, and assume all of the liabilities of MuniBond, in
exchange solely for that number of shares of MuniAssets Common Stock provided in
Section 4 of this Agreement. Pursuant to this Agreement, as soon as practicable
MuniBond will distribute all MuniAssets Common Stock received by it to its
stockholders in exchange for their corresponding MuniBond Common Stock. Such
distribution shall be accomplished by the opening of stockholder accounts on the
stock ledger records of MuniAssets in the amounts due the stockholders of
MuniBond based on their respective holdings in MuniBond as of the Valuation
Time.
 
    (b) MuniBond will pay or cause to be paid any interest it receives on or
after the Exchange Date with respect to the Investments transferred to
MuniAssets hereunder.

   
    (c) The Valuation Time shall be 4:00 P.M., New York time, on
December 19, 1994, or such earlier or later day and time as mutually may be
agreed upon in writing (the "Valuation Time").
    
 
    (d) MuniAssets will acquire substantially all of the assets of, and assume
all of the known liabilities of, MuniBond, except that recourse for such
liabilities will be limited to MuniAssets. The known liabilities of MuniBond as
of the Valuation Time shall be confirmed in writing to MuniAssets by MuniBond
pursuant to Section 1(k) of this Agreement.
 
    4. Issuance and Valuation of MuniAssets Common Stock in the
Reorganization. Full shares of MuniAssets Common Stock of an aggregate net
asset value or liquidation preference, as the case may be, equal (to the
nearest one ten thousandth of one cent) to the value of the assets of MuniBond
acquired, determined as hereinafter provided, reduced by the amount of
liabilities assumed by MuniAssets, shall be issued by MuniAssets in exchange
for such assets of MuniBond. The assets of MuniBond and MuniAssets shall be
determined in accordance with the procedures described in the MuniAssets Common
Stock Prospectus as of the Valuation Time, and no formula will be used to
adjust the net asset value so determined of either MuniBond or MuniAssets to
take into account differences in realized and unrealized gains and losses.
Values in all cases shall be determined as of the Valuation Time. The value of
the Investments of MuniBond to be transferred to MuniAssets shall be determined
by MuniAssets pursuant to the procedures utilized by MuniAssets in valuing its
own assets and determining its own liabilities for purposes of the
Reorganization. Such valuation and determination shall be made by MuniAssets in
cooperation with MuniBond and shall be confirmed in writing to MuniAssets by
MuniBond. The net asset value per share of the MuniAssets Common Stock shall
be determined in accordance with such procedures and MuniAssets shall certify
the computations involved. MuniAssets shall issue to MuniBond separate
certificates or share deposit receipts for the MuniAssets Common Stock
registered in the name of MuniBond. MuniBond then shall distribute the
MuniAssets Common Stock to its corresponding stockholders of MuniBond Common
Stock by redelivering the certificates or share deposit receipts evidencing
ownership of the MuniAssets Common Stock to The Bank of New York, as the
transfer agent and registrar for the MuniAssets Common Stock. With respect to
any MuniBond stockholder holding certificates evidencing ownership of the
MuniBond Common Stock as of
 
                                      I-7
<PAGE>
the Exchange Date, and subject to MuniAssets being informed thereof in writing
by MuniBond, MuniAssets will not permit such stockholder to receive new
certificates evidencing ownership of the MuniAssets Common Stock, exchange
MuniAssets Common Stock credited to such stockholder's account for shares of
other investment companies managed by Merrill Lynch Asset Management, L.P. or
any of its affiliates, or pledge or redeem such MuniAssets Common Stock, in any
case, until notified by MuniBond or its agent that such stockholder has
surrendered his or her outstanding certificates evidencing ownership of the
MuniBond Common Stock or, in the event of lost certificates, posted adequate
bond. MuniBond, at its own expense, will request its stockholders to surrender
their outstanding certificates evidencing ownership of the MuniBond Common
Stock, as the case may be, or post adequate bond therefor.
 
    5. Payment of Expenses. (a) With respect to expenses incurred in connection
with the Reorganization, MuniAssets shall pay, subsequent to the Exchange Date,
all expenses incurred in connection with the Reorganization, including, but not
limited to, all costs related to the preparation and distribution of the N-14
Registration Statement and the fees of special counsel to the Reorganization.
Such fees and expenses shall include legal, accounting and state securities or
blue sky fees, printing costs, filing fees, stock exchange fees, portfolio
transfer taxes (if any), and any similar expenses incurred in connection with
the Reorganization. Neither MuniBond nor MuniAssets shall pay any expenses of
its respective stockholders arising out of or in connection with the
Reorganization.
 
    (b) If for any reason the Reorganization is not consummated, no party shall
be liable to any other party for any damages resulting therefrom, including,
without limitation, consequential damages.
 
    6. Covenants of MuniBond and MuniAssets. (a) MuniBond and MuniAssets each
agrees to call a meeting of its respective stockholders as soon as is
practicable after the effective date of the N-14 Registration Statement for the
purpose of considering the Reorganization as described in this Agreement. As a
condition to the obligations of each of the parties hereto, the holders of (i)
more than fifty percent of the shares of MuniBond Common Stock, and (ii) more
than fifty percent of the MuniAssets Common Stock in each case issued and
outstanding and entitled to vote thereon, shall have approved this Agreement at
such a meeting at or prior to the Valuation Time.
 
    (b) MuniBond and MuniAssets each covenants to operate its respective
business as presently conducted between the date hereof and the Exchange Date.
 
    (c) MuniBond agrees that following the consummation of the Reorganization,
it will liquidate and dissolve in accordance with the laws of the State of
Maryland and any other applicable law, it will not make any distributions of any
MuniAssets Common Stock other than to the stockholders of MuniBond and without
first paying or adequately providing for the payment of all of MuniBond's
liabilities not assumed by MuniAssets, if any, and on and after the Exchange
Date it shall not conduct any business except in connection with its liquidation
and dissolution.
 
    (d) MuniBond undertakes that if the Reorganization is consummated, it will
file an application pursuant to Section 8(f) of the 1940 Act for an order
declaring that MuniBond has ceased to be a registered investment company.
 
    (e) MuniBond and MuniAssets jointly will file the N-14 Registration
Statement with the Securities and Exchange Commission (the "Commission") and
will use their best efforts to provide that the N-
 
                                      I-8
<PAGE>
14 Registration Statement becomes effective as promptly as practicable. MuniBond
and MuniAssets agree to cooperate fully with each other, and each will furnish
to the other the information relating to itself to be set forth in the N-14
Registration Statement as required by the 1933 Act, 1934 Act, the 1940 Act, and
the rules and regulations thereunder and the state securities or blue sky laws.
 
    (f) MuniAssets agrees to advise MuniBond promptly in writing if at any time
prior to the Exchange Date the assets of MuniBond include any assets which
MuniAssets is not permitted, or reasonably believes to be unsuitable for it, to
acquire, including without limitation any security which, prior to its
acquisition by MuniBond, MuniAssets has informed MuniBond is unsuitable for
MuniAssets to acquire. Moreover, MuniAssets has no plan or intention to sell or
otherwise dispose of the assets of MuniBond to be acquired in the
Reorganization, except for dispositions made in the ordinary course of business.
 
    (g) MuniBond and MuniAssets each agrees that by the Exchange Date all of its
Federal and other tax returns and reports required to be filed on or before such
date shall have been filed and all taxes shown as due on said returns either
have been paid or adequate liability reserves have been provided for the payment
of such taxes. In connection with this covenant, the funds agree to cooperate
with each other in filing any tax return, amended return or claim for refund,
determining a liability for taxes or a right to a refund of taxes or
participating in or conducting any audit or other proceeding in respect of
taxes. MuniAssets agrees to retain for a period of ten years following the
Exchange Date all returns, schedules and work papers and all material records or
other documents relating to tax matters of MuniBond for its taxable period first
ending after the Exchange Date and for all prior taxable periods. Any
information obtained under this subsection shall be kept confidential except as
otherwise may be necessary in connection with the filing of returns or claims
for refund or in conducting an audit or other proceeding. After the Exchange
Date, MuniBond shall prepare, or cause it agents to prepare, any Federal, state
or local tax returns, including any Forms 1099, required to be filed by MuniBond
with respect to MuniBond's final taxable year ending with its complete
liquidation and for any prior periods or taxable years and further shall cause
such tax returns and Forms 1099 to be duly filed with the appropriate taxing
authorities. Notwithstanding the aforementioned provisions of this subsection,
any expenses incurred by MuniBond (other than for payment of taxes) in
connection with the preparation and filing of said tax returns and Forms 1099
after the Exchange Date shall be borne by MuniBond to the extent such expenses
have been accrued by MuniBond in the ordinary course without regard to the
Reorganization; any excess expenses shall be borne by Fund Asset Management,
L.P. ("FAM") at the time such tax returns and Forms 1099 are prepared.
 
    (h) MuniBond and MuniAssets each agrees to mail to each of its respective
stockholders of record entitled to vote at the meeting of stockholders at which
action is to be considered regarding this Agreement, in sufficient time to
comply with requirements as to notice thereof, a combined Proxy Statement and
Prospectus which complies in all material respects with the applicable
provisions of Section 14(a) of the 1934 Act and Section 20(a) of the 1940 Act,
and the rules and regulations, respectively, thereunder.
 
    (i) Following the consummation of the Reorganization, MuniAssets expects to
stay in existence and continue its business as a closed-end management
investment company registered under the 1940 Act.

<PAGE>
    MuniAssets is a party or by which MuniAssets is bound; (vi) MuniAssets, to
    the knowledge of such counsel, is not required to qualify to do business as
    a foreign corporation in any jurisdiction except as may be required by state
    securities or blue sky laws, and except where it has so qualified or the
    failure so to qualify would not have a material adverse effect on
    MuniAssets, or its stockholders; (vii) such counsel does not have actual

    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 their
    attention that would lead them 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

    the statements therein not misleading; and (2) the prospectus and statement
    of additional information included in the N-14 Registration Statement

    counsel do not express any opinion or belief as to the financial statements,
    other financial data, statistical data or information relating to MuniAssets
    contained or incorporated by reference in the N-14 Registration Statement.

    relying on certificates of officers of MuniAssets with regard to matters of
    fact and certain certificates and written statements of governmental
    officials with respect to the good standing of MuniAssets and on the opinion
    of Galland, Kharasch, Morse & Garfinkle, P.C. as to matters of Maryland law.
 
   
        (g) That MuniBond shall have received either (a) a private letter ruling
    from the Internal Revenue Service or (b) an opinion of Rogers & Wells, to
    the effect that for Federal income tax purposes (i) the transfer of
    substantially all of the Investments of MuniBond to MuniAssets in exchange

    or property other than MuniAssets Common Stock received; (v) in accordance
    with Section 1032 of the Code, no gain or loss will be recognized by the
    stockholders of MuniAssets upon the issuance of MuniAssets Common Stock and
    the distribution of such MuniAssets Common Stock to MuniBond stockholders in
    the Reorganization; (vi) in accordance with Section 362(b) of the Code, the
    basis to MuniAssets of the Investments will be the same as the basis of the
    Investments in the hands of
    
 
                                      I-12
<PAGE>
    MuniBond immediately prior to the consummation of the Reorganization, except
    for any necessary adjustment on account of cash or property received; (vii)
    in accordance with Section 1223 of the Code, a stockholder's holding period
    for his MuniAssets Common Stock will be determined by including the period
    for which he or she held the MuniBond Common Stock exchanged therefor,
    provided that he or she held such MuniBond shares as a capital asset; (viii)
    in accordance with Section 1223 of the Code, MuniAssets's holding period
    with respect to the Investments will include the period for which such
    Investments were held by MuniBond; and (ix) no gain or loss will be
    recognized to MuniBond or its stockholders upon the liquidation of MuniBond
    in connection with the Reorganization. In addition, such opinion shall state
    that, without any independent investigation having been made with respect to
    the qualification of either MuniBond or MuniAssets as a regulated investment
    company under the Code and based upon certain representations by MuniBond
    and MuniAssets, the status of MuniBond and MuniAssets as regulated
    investment companies under Sections 851-855 of the Code will not be affected
    as a result of the Reorganization, except that upon the liquidation of
    MuniBond in connection with the Reorganization its regulated investment
    company status will terminate.
 
        (h) That all proceedings taken by MuniAssets and its counsel in
    connection with the Reorganization and all documents incidental thereto
    shall be satisfactory in form and substance to MuniBond.
 
        (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 MuniAssets, contemplated by the
    Commission.
 
        (j) That MuniBond shall have received from Deloitte & Touche LLP a
    letter dated as of the effective date of the N-14 Registration Statement
    and a similar letter dated within five days prior to the Exchange Date, in
    form and substance satisfactory to MuniBond, to the effect that (i) they are
    independent public accountants with respect to MuniAssets 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 MuniAssets 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; (iii) on the basis of limited procedures agreed upon by MuniBond
    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 MuniAssets included in the N-14 Registration Statement, and
    inquiries of certain officials of MuniAssets responsible for financial and
    accounting matters, nothing came to their 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 principles, applied on a basis substantially consistent with that
    of the audited financial statements, or (c) such unaudited supplementary
    information is not fairly stated in all material respects in relation to the
    unaudited financial
 
                                      I-13
<PAGE>
    statements taken as a whole; and (iv) on the basis of limited procedures
    agreed upon by MuniBond and described in such letter (but not an examination
    in accordance with generally accepted auditing standards), the information
    relating to MuniAssets appearing in the N-14 Registration Statement, which
    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 MuniAssets or from
    schedules prepared by officials of MuniAssets 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, no other legal,
    administrative or other proceeding shall be instituted or threatened which
    would materially affect the financial condition of MuniAssets or would
    prohibit the Reorganization.
 
        (j) That MuniBond shall have received from the Commission such orders or
    interpretations as Brown & Wood, as counsel to MuniBond, deems reasonably
    necessary or desirable under the 1933 Act and 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.
 
    9. MuniAssets Conditions. The obligations of MuniAssets 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 affirmative vote of the holders of more
    than fifty percent of the MuniBond Common Stock issued and outstanding and
    entitled to vote thereon; and that MuniBond shall have delivered to
    MuniAssets a copy of the resolution approving this Agreement adopted by
    MuniBond's Board of Directors, certified by the Secretary of MuniBond.
 
        (b) That MuniBond shall have furnished to MuniAssets a statement of
    MuniBond's assets, liabilities and capital, 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 MuniBond'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 there has been no
    material adverse change in the financial position of MuniBond since May 31,
    1994, other than changes in the Investments since that date or changes in
    the market value of the Investments.
 
        (c) That MuniBond shall have furnished to MuniAssets a certificate
    signed by MuniBond's President (or any Vice President) and its Treasurer,
    dated the Exchange Date, certifying that as of the Valuation Time and as of
    the Exchange Date all representations and warranties of MuniBond made in
    this Agreement are true and correct in all material respects as if made at
    and as of such date and MuniBond has complied with all of the agreements and
    satisfied all of the conditions on its part to be performed or satisfied at
    or prior to such dates.
 
                                      I-14
<PAGE>
        (d) That MuniBond shall have delivered to MuniAssets a letter from
    Deloitte & Touche LLP, dated the Exchange Date, stating that such firm has
    performed a limited review of the Federal, state and local income tax
    returns of MuniBond for the period ended May 31, 1994 (which returns
    originally were prepared and filed by MuniBond), 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 MuniBond for the period covered
    thereby; and that for the period from May 31, 1994 to and including the
    Exchange Date such firm has performed a limited review to ascertain the
    amount of applicable Federal, state and local taxes, and has determined that
    either such amount has been paid or reserves established for 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 May 31, 1994 to and
    including the Exchange Date and for any taxable year of MuniBond ending upon
    the liquidation of MuniBond or that MuniBond would not continue to qualify
    as a regulated investment company for Federal income tax purposes.
 
        (e) That there shall not be any material litigation pending with respect
    to the matters contemplated by this Agreement.
 
        (f) That MuniAssets shall have received an opinion of Galland, Kharasch,
    Morse & Garfinkle, P.C., Maryland counsel to MuniBond, in form satisfactory
    to MuniAssets and dated the Exchange Date, to the effect that (i) MuniBond
    is a corporation duly organized, validly existing and in good standing in
    conformity with the laws of the State of Maryland; (ii) this Agreement has
    been duly authorized, executed and delivered by MuniBond, and represents 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, 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)
    MuniBond 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, MuniBond will have duly
    transferred such assets and liabilities in accordance with this Agreement;
    (iv) the execution and delivery of this Agreement does not, and the
    consummation of the Reorganization will not, violate the Articles of
    Incorporation, as amended, or the by-laws of MuniBond; (v) no consent,
    approval, authorization or order of any Maryland court or governmental
    authority is required for the consummation by MuniBond of the
    Reorganization, except such as have been obtained under Maryland law; and
    (vi) such opinion is solely for the benefit of MuniAssets and its Directors
    and officers.
 
        (g) That MuniAssets shall have received an opinion of Brown & Wood, as
    counsel to MuniBond, in form satisfactory to MuniAssets and dated the

    Internal Revenue Service or opinion of Rogers & Wells with respect to the
    matters specified in Section 8(g) of this Agreement.
 
        (i) That MuniAssets shall have received from Deloitte & Touche LLP a
    letter dated as of the effective date of the N-14 Registration Statement
    and a similar letter dated within five days prior to the Exchange Date, in
    form and substance satisfactory to MuniAssets, to the effect that (i) they
    are independent public accountants with respect to MuniBond 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 MuniBond 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; (iii) on the
    basis of limited procedures agreed upon by MuniAssets 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 MuniBond
    included in the N-14 Registration Statement, and inquiries of certain
    officials of MuniBond responsible for financial and accounting matters,
    nothing came to their 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
    principles, applied on a basis substantially consistent with that of the
    audited financial statements, or (c) such unaudited supplementary
    information is not fairly stated in all material respects in relation to the
    unaudited financial statements taken as a whole; and (iv) on the basis of
    limited procedures agreed upon by MuniAssets and described in such letter
    (but not an examination in accordance with generally accepted auditing
    standards), the information relating to MuniBond appearing in the N-14
    Registration Statement, which 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 MuniBond or from schedules prepared by officials of MuniBond having
    responsibility for financial and reporting matters and such information is
    in agreement with such records, schedules or computations made therefrom.
 
        (j) That the Investments to be transferred to MuniAssets shall not
    include any assets or liabilities which MuniAssets, by reason of charter
    limitations or otherwise, may not properly acquire or assume.
 
        (k) 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 MuniBond, contemplated by the
    Commission.
 
        (l) That the Commission shall not have issued an unfavorable advisory
    report under Section 25 (b) of the 1940 Act, nor instituted or threatened to

                                      I-16
<PAGE>
    administrative or other proceeding shall be instituted or threatened which
    would materially affect the financial condition of MuniBond or would
    prohibit the Reorganization.
 
        (m) That MuniAssets shall have received from the Commission such orders
    or interpretations as Rogers & Wells, as counsel to MuniAssets, deems
    reasonably necessary or desirable under the 1933 Act and 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.
 
        (n) That all proceedings taken by MuniBond and its counsel in connection
    with the Reorganization and all documents incidental thereto shall be
    satisfactory in form and substance to MuniAssets.
 
        (o) That prior to the Exchange Date, MuniBond shall have declared a
    dividend or dividends which, together with all previous such dividends,
    shall have the effect of distributing to its stockholders all of its net
    investment company taxable income for the period from November 1, 1993 to
    and including the Exchange Date, if any (computed without regard to any
    deduction or dividends paid), and all of its net capital gain, if any,

10. Termination, Postponement and Waivers.
 
    (a) Notwithstanding anything contained in this Agreement to the contrary,
this Agreement may be terminated and the Reorganization abandoned at any time
(whether before or after adoption thereof by the stockholders of each of
MuniBond and MuniAssets) prior to the Exchange Date, or the Exchange Date may be
postponed, (i) by mutual written consent of the Boards of Directors of MuniBond
and MuniAssets; (ii) by the Board of Directors of MuniBond if any condition of
MuniBond's obligations set forth in Section 8 of this Agreement has not been

of this Agreement has not been fulfilled or waived by such Board.
 
    (b) If the transactions contemplated by this Agreement have not been
consummated by December 31, 1994, this Agreement automatically shall terminate
on that date, unless a later date is mutually agreed to by the Boards of
Directors of MuniBond and MuniAssets.
 
    (c) In the event of termination of this Agreement pursuant to the provisions
hereof, the same shall become void and have no further effect, and there shall
not be any liability on the part of either MuniBond or MuniAssets or persons who
are their directors, trustees, officers, agents or stockholders in respect of
this Agreement.
 
    (d) At any time prior to the Exchange Date, any of the terms or conditions
of this Agreement may be waived by the Board of Directors of either MuniBond or
MuniAssets, respectively (whichever is entitled to the benefit thereof), if, in
the judgment of such Board after consultation with its counsel, such action or
waiver will not have a material adverse effect on the benefits intended under
this Agreement to the stockholders of their respective fund, on behalf of which
such action is taken. In addition, the Board of Directors of both MuniBond and
MuniAssets hereby delegate to FAM the ability to make non-
 
                                      I-17
<PAGE>
material changes to the transaction if it deems it to be in the best interests
of both MuniBond and MuniAssets to do so.
 
    (e) The respective representations and warranties contained in Sections 1
and 2 of this Agreement shall expire with, and be terminated by, the
consummation of the Reorganization, and neither MuniBond nor MuniAssets nor any
of their officers, directors or trustees, agents or stockholders shall have any
liability with respect to such representations or warranties after the Exchange
Date. This provision shall not protect any officer, director or trustee, agent
or stockholder of MuniBond or MuniAssets against any liability to the entity for
which that officer, director or trustee, agent or stockholder so acts or to its
stockholders to which that officer, director or trustee, agent or stockholder
otherwise would be subject by reason of willful misfeasance, bad faith, gross
negligence, or reckless disregard of the duties in the conduct of such office.
 
    (f) If any order or orders of the Commission with respect to this Agreement
shall be issued prior to the Exchange Date and shall impose any terms or
conditions which are determined by action of the Boards of Directors of MuniBond
and MuniAssets to be acceptable, such terms and conditions shall be binding as
if a part of this Agreement without further vote or approval of the
stockholders of MuniBond and MuniAssets, unless such terms and conditions shall
result in a change in the method of computing the number of shares of MuniAssets
Common Stock to be issued to MuniBond in which event, unless such terms and
conditions shall have been included in the proxy solicitation materials
furnished to the stockholders of MuniBond and MuniAssets prior to the meeting at
which the Reorganization shall have been approved, this Agreement shall not be
consummated and shall terminate unless MuniBond and MuniAssets promptly shall
call special meetings of stockholders at which such conditions so imposed shall
be submitted for approval.
 
    11. Indemnification. (a) MuniBond hereby agrees to indemnify and hold
MuniAssets harmless from all loss, liability and expense (including reasonable
counsel fees and expenses in connection with the contest of any claim) which
MuniAssets may incur or sustain by reason of the fact that (i) MuniAssets shall
be required to pay any corporate obligation of MuniBond, whether consisting of
tax deficiencies or otherwise, based upon a claim or claims against MuniBond
which were omitted or not fairly reflected in the financial statements to be
delivered to MuniAssets in connection with the Reorganization; (ii) any
representations or warranties made by MuniBond in this Agreement should prove to
be false or erroneous in any material respect; (iii) any covenant has been
breached in any material respect; or (iv) any claim is made alleging that (a)
the N-14 Registration Statement included 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 or (b) the Proxy Statement and
Prospectus delivered to the stockholders of MuniBond and forming a part of the
N-14 Registration Statement included 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,
except insofar as such claim is based on written information furnished to
MuniBond by MuniAssets.
 
    (b) MuniAssets hereby agrees to indemnify and hold MuniBond harmless from
all loss, liability and expenses (including reasonable counsel fees and expenses
in connection with the contest of any claim) which MuniBond may incur or sustain
by reason of the fact that (i) any representations or
 
                                      I-18
<PAGE>
warranties made in this Agreement should prove false or erroneous in any
material respect, (ii) any covenant has been breached in any material respect,
or (iii) any claim is made alleging that (a) the N-14 Registration Statement
included 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 or (b) the Proxy Statement and Prospectus delivered to
the stockholders of MuniAssets and forming a part of the N-14 Registration
Statement included 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, except insofar as such
claim is based on written information furnished to MuniAssets by MuniBond.
 
    (c) In the event that any claim is made against MuniAssets in respect of
which indemnity may be sought by MuniAssets from MuniBond under Section 11(a) of
this Agreement, or in the event that any claim is made against MuniBond in
respect of which indemnity may be sought by MuniBond from MuniAssets under
Section 11(b) of this Agreement, then the party seeking indemnification (the
"Indemnified Party"), with reasonable promptness and before payment of such
claim, shall give written notice of such claim to the other party (the
"Indemnifying Party"). If no objection as to the validity of the claim is made
in writing to the Indemnified Party by the Indemnifying Party within thirty (30)
days after the giving of notice hereunder, then the Indemnified Party may pay
such claim and shall be entitled to reimbursement therefor, pursuant to this
Agreement. If, prior to the termination of such thirty-day period, objection in
writing as to the validity of such claim is made to the Indemnified Party, the
Indemnified Party shall withhold payment thereof until the validity of such
claim is established (i) to the satisfaction of the Indemnifying Party, or (ii)
by a final determination of a court of competent jurisdiction, whereupon the
Indemnified Party may pay such claim and shall be entitled to reimbursement
thereof, pursuant to this Agreement, or (iii) with respect to any tax claims,
within seven calendar days following the earlier of (A) an agreement between
MuniBond and MuniAssets that an indemnity amount is payable, (B) an assessment
of a tax by a taxing authority, or (C) a "determination" as defined in Section
1313(a) of the Code. For purposes of this Section 11, the term "assessment"
shall have the same meaning as used in Chapter 63 of the Code and Treasury
Regulations thereunder, or any comparable provision under the laws of the
appropriate taxing authority. In the event of any objection by the Indemnifying
Party, the Indemnifying Party promptly shall investigate the claim, and if it is
not satisfied with the validity thereof, the Indemnifying 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.
 
    12. Other Matters. (a) Pursuant to Rule 145 under the 1933 Act, and in
connection with the issuance of any shares to any person who at the time of the
Reorganization is, to its knowledge, an affiliate of a party to the
Reorganization pursuant to Rule 145(c), MuniAssets will cause to be affixed upon
the certificate(s) issued to such person (if any) a legend as follows:
 
    THESE SHARES ARE SUBJECT TO RESTRICTIONS ON TRANSFER UNDER THE SECURITIES
    ACT OF 1933 AND MAY NOT BE SOLD OR OTHERWISE TRANSFERRED EXCEPT TO
    MUNIASSETS FUND, INC. (OR ITS STATUTORY SUCCESSOR) OR ITS PRICING
    UNDERWRITER UNLESS (I) A REGISTRATION STATEMENT WITH RESPECT THERETO IS
    EFFECTIVE UNDER THE SECURITIES ACT OF 1933 OR (II) IN THE OPINION OF
 
                                      I-19
<PAGE>
    COUNSEL REASONABLY SATISFACTORY TO THE FUND, SUCH REGISTRATION IS NOT
    REQUIRED.
 
and, further, that stop transfer instructions will be issued to MuniAssets's
transfer agent with respect to such shares. MuniBond will provide MuniAssets on
the Exchange Date with the name of any MuniBond stockholder who is to the
knowledge of MuniBond an affiliate of it on such date.
 
    (b) All covenants, agreements, representations and warranties made under
this Agreement and any certificates delivered pursuant to this Agreement shall
be deemed to have been material and relied upon by each of the parties,
notwithstanding any investigation made by them or on their behalf.
 
    (c) Any notice, report or demand required or permitted by any provision of
this Agreement shall be in writing and shall be deemed to have been given if
delivered or mailed, first class postage prepaid, addressed to MuniBond or
MuniAssets, in either case at 800 Scudders Mill Road, Plainsboro, New Jersey
08536, Attn: Arthur Zeikel, President.
 
    (d) This Agreement supersedes all previous correspondence and oral
communications between the parties regarding the Reorganization, constitutes the
only understanding with respect to the Reorganization, may not be changed except
by a letter of agreement signed by each party and shall be governed by and
construed in accordance with the laws of the State of New York applicable to

MuniAssets are on file with the Department of Assessments and Taxation of the
State of Maryland and notice is hereby given that this instrument is executed on

                                  APPENDIX II
                RATINGS OF MUNICIPAL BONDS AND COMMERCIAL PAPER
    
 
DESCRIPTION OF MOODY'S INVESTORS SERVICE, INC.'S ("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 sometime in the future.
 
    Baa--Bonds which are rated Baa are considered as medium grade obligations,
i.e., they are neither highly protected nor poorly secured. Interest payment and
principal security appear adequate for the present but certain protective
elements may be lacking or may be characteristically unreliable over any great
length of time. Such bonds lack outstanding investment characteristics and in
fact have speculative characteristics as well.
 
    Ba--Bonds which are rated Ba are judged to have speculative elements; their
future cannot be considered as well assured. Often the protection of interest
and principal payments may be very moderate and thereby not well safeguarded
during both good and bad times over the future. Uncertainty of position
characterizes bonds in this class.
 
    B--Bonds which are rated B generally lack characteristics of the desirable
investment. Assurance of interest and principal payment or of maintenance of
other terms of the contract over any long period of time may be small.
 
    Caa--Bonds which are rated Caa are of poor standing. Such bonds 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.
 
    Rating Refinements: Moody's may apply numerical modifiers, l, 2 and 3 in
each generic rating classification from Aa through B in its municipal bond
rating system. The modifier 1 indicates that the
 
                                      II-1
<PAGE>
security ranks in the higher end of its generic rating category; the modifier 2
indicates a mid-range ranking; and the modifier 3 indicates that the issue ranks
in the lower end of its generic rating category.
 
    Short-term Notes. The four ratings of Moody's for short-term notes are
MIG-1, MIG-2, MIG-3, and MIG-4; MIG-1 denotes "best quality, enjoying strong
protection by established cash flows"; MIG-2 denotes "high quality" with ample
margins of protection; MIG-3 notes are of "favorable quality ... but lacking the
undeniable strength of the preceding grades"; MIG-4 notes are of "adequate
quality, carrying specific risk but having protection ... and not distinctly or
predominantly speculative".
 
DESCRIPTION OF MOODY'S COMMERCIAL PAPER RATINGS
 
    Moody's Commercial Paper ratings are opinions of the ability of issuers to
repay punctually promissory obligations not having an original maturity in
excess of nine months. Moody's employs the following three designations, all
judged to be investment grade, to indicate the relative repayment capacity of
rated issuers:
 
        Issuers rated Prime-1 (or related supporting institutions) have a
    superior capacity for repayment of short-term promissory obligations.
    Prime-1 repayment capacity will normally be evidenced by the following
    characteristics: leading market positions in well established industries;
    high rates of return on funds employed; conservative capitalization
    structures with moderate reliance on debt and ample asset protection; broad
    margins in earning coverage of fixed financial charges and high internal
    cash generation; and well established access to a range of financial markets
    and assured sources of alternate liquidity.
 
        Issuers rated Prime-2 (or related supporting institutions) have a strong
    capacity for repayment of short-term promissory obligations. This will
    normally be evidenced by many of the characteristics cited above but to a
    lesser degree. Earnings trends and coverage ratios, while sound, will be
    more subject to variation. Capitalization characteristics, while still
    appropriate, may be more affected by external conditions. Ample alternate
    liquidity is maintained.
 
        Issuers rated Prime-3 (or related supporting institutions) have an
    acceptable capacity for repayment of short-term promissory obligations. The
    effect of industry characteristics and market composition may be more
    pronounced. Variability in earnings and profitability may result in changes
    in the level of debt protection measurements and the requirement for
    relatively high financial leverage. Adequate alternate liquidity is
    maintained.
 
        Issuers rated Not Prime do not fall within any of the Prime rating
    categories.
 
    If an issuer represents to Moody's that its Commercial Paper obligations are
supported by the credit of another entity or entities, then the name or names of
such supporting entity or entities are listed within parentheses beneath the
name of the issuer, or there is a footnote referring the reader to another page
for the name or names of the supporting entity or entities. In assigning ratings
to such issuers, Moody's evaluates the financial strength of the indicated
affiliated corporations, commercial banks, insurance companies, foreign
governments or other entities, but only as one factor in the total rating
assessment. Moody's makes no representations and gives no opinion on the legal
validity or enforceability of any support arrangement. You are cautioned to
review with your counsel any questions regarding particular support
arrangements.

 DESCRIPTION OF STANDARD & POOR'S CORPORATION'S ("STANDARD & POOR'S") MUNICIPAL
                                  DEBT RATINGS
 
    A Standard & Poor's municipal debt rating is a current assessment of the
creditworthiness of an obligor with respect to a specific obligation. This
assessment may take into consideration obligors such as guarantors, insurers, or
lessees.
 
    The debt rating is not a recommendation to purchase, sell or hold a
security, inasmuch as it does not comment as to market price or suitability for
a particular investor.
 
    The ratings are based on current information furnished by the issuer or
obtained by Standard & Poor's from other sources Standard & Poor's considers
reliable. Standard & Poor's does not perform an audit in connection with any
rating and may, on occasion, rely on unaudited financial information. The
ratings may be changed, suspended or withdrawn as a result of changes in, or
unavailability of, such information, or for other reasons.
 
    The ratings are based, in varying degrees, on the following considerations:
 
         I. Likelihood of default--capacity and willingness of the obligor as to
    the timely payment of interest and repayment of principal in accordance with
    the terms of the obligation;
 
         II. Nature of and provisions of the obligation;
 
        III. Protection afforded by, and relative position of, the obligation in
    the event of bankruptcy, reorganization or other arrangement under the laws
    of bankruptcy and other laws affecting creditors' rights.
 
    AAA--Debt rated "AAA" has the highest rating assigned by Standard & Poor's.
Capacity to pay interest and repay principal is extremely strong.
 
    AA--Debt rated "AA" has a very strong capacity to pay interest and repay
principal and differs from the highest-rated issues only in small degree.
 
    A--Debt rated "A" has a strong capacity to pay interest and repay principal
although they are somewhat more susceptible to the adverse effects of changes in
circumstances and economic conditions than debt in higher-rated categories.
 
    BBB--Debt rated "BBB" is regarded as having an adequate capacity to pay
interest and repay principal. Whereas it normally exhibits adequate protection
parameters, adverse economic conditions or changing circumstances are more
likely to lead to a weakened capacity to pay interest and repay principal for
debt in this category than for debt in higher-rated categories.
 
    Debt rated BB, B, CCC, CC and C are regarded as having predominantly
speculative characteristics with respect to capacity to pay interest and repay
principal. BB indicates the least degree of speculation and C the highest degree
of speculation. While such debt will likely have some quality and protective
characteristics, these are outweighed by large uncertainties or major risk
exposures to adverse conditions.
 
    BB--Debt rated "BB" has less near-term vulnerability to default than other
speculative grade debt. However, it faces major ongoing uncertainties or
exposure to adverse business, financial or
 
                                      II-3
<PAGE>
economic conditions which could lead to inadequate capacity to meet timely
interest and principal payments. The BB rating category is also used for debt
subordinated to senior debt that is assigned an actual or implied BBB- rating.
 
    B--Debt rated "B" has a greater vulnerability to default but presently has
the capacity to meet interest payments and principal repayments. Adverse
business, financial or economic conditions would likely impair capacity or
willingness to pay interest and repay principal. The B rating category is also
used for debt subordinated to senior debt that is assigned an actual or implied
BB or BB- rating.
 
    CCC--Debt rated "CCC" has a current identifiable vulnerability to default,
and is dependent upon favorable business, financial and economic conditions to
meet timely payments of interest and repayments of principal. In the event of
adverse business, financial or economic conditions, it is not likely to have the
capacity to pay interest and repay principal. The CCC rating category is also
used for debt subordinated to senior debt that is assigned an actual or implied
B or B- rating.
 
    CC--The rating "CC" is typically applied to debt subordinated to senior debt
which is assigned an actual or implied CCC rating.
 
    C--The rating "C" is typically applied to debt subordinated to senior debt
which is assigned an actual or implied CCC- debt rating. The C rating may be
used to cover a situation where a bankruptcy petition has been filed but debt
service payments are continued.
 
    CI--The rating "CI" is reserved to income bonds on which no interest is
being paid.
 
    D--Debt rated "D" is in default. The D rating category is also used when
interest payments or principal repayments are expected to be in default at the
payment date, and payment of interest and/or repayment of principal is in
arrears. The D rating also will be used upon the filing of a bankruptcy petition
if debt service payments are jeopardized.
 
    Plus (+) or Minus (-): The ratings from "AA" to "BBB" may be modified by the
addition of a plus or minus sign to show relative standing within the major
rating categories.
 
    Provisional ratings: The letter "p" indicates that the rating is
provisional. A provisional rating assumes the successful completion of the
project being financed by the debt being rated and indicates that payment of
debt service requirements is largely or entirely dependent upon the successful
and timely completion of the project. This rating, however, while addressing
credit quality subsequent to completion of the project, makes no comment on the
likelihood or risk of default upon failure of such completion. The investor
should exercise judgment with respect to such likelihood and risk.
 
    L: The letter "L" indicates that the rating persons to the principal amount
of those bonds to the extent that the underlying deposit collateral is insured
by the Federal Savings & Loan Insurance Corp. or the Federal Deposit Insurance
Corp. and interest is adequately collateralized.
 
    *: Continuance of the rating is contingent upon Standard & Poor's receipt of
an executed copy of the escrow agreement or closing documentation confirming
investments and cash flows.
 
                                      II-4
<PAGE>
    NR: Indicates that no rating has been requested, that there is insufficient
information on which to base a rating or that Standard & Poor's does not rate a
particular type of obligation as a matter of policy.
 
    Debt Obligations of Issuers outside the United States and its territories
are rated on the same basis as domestic corporate and municipal issues. The
ratings measure the creditworthiness of the obligor but do not take into account
currency exchange and related uncertainties.
 
    BOND INVESTMENT QUALITY STANDARDS: Under present commercial bank regulations
issued by the Comptroller of the Currency, bonds rated in the top four
categories ("AAA", "AA", "A", "BBB", commonly known as "investment grade"
ratings) are generally regarded as eligible for bank investment. In addition,
the laws of various states governing legal investments impose certain rating or
other standards for obligations eligible for investment by savings banks, trust
companies, insurance companies and fiduciaries generally.
 
DESCRIPTION OF STANDARD & POOR'S COMMERCIAL PAPER RATINGS
 
    A Standard & Poor's Commercial Paper Rating is a current assessment of the
likelihood of timely payment of debt having an original maturity of no more than
365 days. Ratings are graded into four categories, ranging from "A" for the
highest quality obligations to "D" for the lowest. Ratings are applicable to
both taxable and tax-exempt commercial paper. The three designations in the "A"
category are as follows:
 
        A--Issues assigned this highest rating are regarded as having the
    greatest capacity for timely payment. Issues in this category are further
    refined with the designation 1, 2 and 3 to indicate the relative degree of
    safety.
 
        A-1--This designation indicates that the degree of safety regarding
    timely payment is either overwhelming or very strong. Those issues
    determined to possess extremely strong safety characteristics are denoted
    with a "+" designation.
 
        A-2--Capacity for timely payment on issues with this designation is
    strong. However, the relative degree of safety is not as overwhelming as for
    issues designated "A-1".
 
        A-3--Issues carrying this designation have a satisfactory capacity for
    timely payment. They are, however, somewhat more vulnerable to the adverse
    effects of changes in circumstances than obligations carrying the higher
    designations.
 
    The Commercial Paper Rating is not a recommendation to purchase or sell a
security. The ratings are based on current information furnished to Standard &
Poor's by the issuer 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.
 
                                      II-5
<PAGE>
    Commencing on July 27, 1984, Standard & Poor's instituted a new rating
category with respect to certain municipal note issues with a maturity of less
than three years. The new note ratings and symbols are:
 
        SP-1 A very strong, or strong, capacity to pay principal and interest.
    Issues that possess overwhelming safety characteristics will be given a "+"
    designation.
 
        SP-2 A satisfactory capacity to pay principal and interest.
 
        SP-3 A speculative capacity to pay principal and interest.
 
    Standard & Poor's may continue to rate issues with a maturity greater than
three years in accordance with the same rating scale currently employed for
municipal bond ratings.
 
    Unrated: Where no rating has been assigned or where a rating has been
suspended or withdrawn, it may be for reasons unrelated to the quality of the
issue.
 
    Should no rating be assigned, the reason may be one of the following:
 
        1. An application for rating was not received or accepted.
 
        2. The issue or issuer belongs to a group of securities that are not
    rated as a matter of policy.
 
        3. There is a lack of essential data pertaining to the issue or issuer.
 
        4. The issue was privately placed, in which case the rating is not
    published in Standard & Poor's publications.
 
    Suspension or withdrawal may occur if new and material circumstances arise,
the effects of which preclude satisfactory analysis; if there is no longer
available reasonable up-to-date information to permit a judgment to be formed;
if a bond is called for redemption; or for other reasons.
 
DESCRIPTION OF FITCH INVESTOR SERVICE, INC.'S ("FITCH") INVESTMENT GRADE BOND
RATINGS
 
    Fitch investment grade bond ratings provide a guide to investors in
determining the credit risk associated with a particular security. The ratings
represent Fitch's assessment of the issuer's ability to meet the obligations of
a specific debt issue or class of debt.
 
    The rating takes into consideration special features of the issue, its
relationship to other obligations of the issuer, the current 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.
 
    Bonds that have the same rating are of similar but not necessarily identical
credit quality since the rating categories do not fully reflect small
differences in the degrees of credit risk.
 
    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.
 
                                      II-6
<PAGE>
    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.
 
    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.
 
    Trend Indicator: Trend indicators show whether credit fundamentals are
improving, stable, declining, or uncertain as follows:
 
Improving
Stable
Declining
Uncertain
 
    Trend indicators are not predictions that any rating change will occur.
 
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.
 
    Withdrawn. A rating may be withdrawn when an issue matures or is called or
refinanced or, at Fitch's discretion, when an issuer fails to furnish proper and
timely information.
 
    FitchAlert: Ratings are placed on FitchAlert to notify investors of an
occurrence that is likely to result in a rating change and the likely direction
of such change. These are designated as "Positive" indicating a potential
upgrade; "Negative" for potential downgrade, or "Evolving" where ratings may be
raised or lowered. FitchAlert is relatively short-term, and should be resolved
within 12 months. Once Fitch completes its analysis of the event, appropriate
rating action will be taken and the issue will be removed from FitchAlert.
Ratings will also be placed on FitchAlert to notify investors of an upcoming
event that is likely to result in a rating change (e.g., court or regulatory
action that could result in material liability of an issuer or impair the
enforceability of debt obligations). In these instances, FitchAlert will
indicate the effect that various possible results might have on the rating.
 
                                      II-7
<PAGE>
DESCRIPTION OF FITCH HIGH YIELD BOND RATINGS
 
    Fitch high yield bond ratings provide a guide to investors in determining
the credit risk associated with a security. The rating is an assessment of the
likelihood of timely payment of principal and interest in accordance with the
terms of obligation for bond issues not in default. Bonds in default are rated
"DDD", "DD", or "D".
 
    The rating takes into consideration special features of the issue, the
relationship to other obligations of the issuer, the current and prospective
financial condition and operating performance of the issuer and any guarantor,
as well as the economic and political environment that might affect the issuer's
future financial strength.
 
    It should be noted that revenues that have the same rating are of similar
but not necessarily identical credit quality since rating categories cannot
fully reflect the differences in degrees of credit risk.
 
<TABLE>
<C>              <S>
             BB  Bonds are considered speculative. The obligor's ability to pay
                 interest and repay principal may be affected over time by adverse
                 economic changes. However, business and financial alternatives can be
                 identified that could assist the obligor in satisfying its debt
                 service requirements.
              B  Bonds are considered highly speculative. While bonds in this class are
                 currently meeting debt service requirements, the probability of
                 continued timely payment of principal and interest reflects the
                 obligor's limited margin of safety and the need for reasonable
                 business and economic activity throughout the life of the issue.
            CCC  Bonds have certain identifiable characteristics which, if not
                 remedied, may lead to default. The ability to meet obligations
                 requires an advantageous business and economic environment.
             CC  Bonds are minimally protected. Default in payment of interest and/or
                 principal seems probable over time.
              C  Bonds are in imminent default in payment of interest or principal.
 DDD, DD, and D  Bonds are in actual or imminent default of interest and/or principal
                 payments. Such bonds are extremely speculative and should be valued on
                 the basis of their ultimate recovery value in liquidation or
                 reorganization of the obligor. "DDD" represents the highest potential
                 for recovery on these bonds, and "D" represents the lowest potential
                 recovery.
</TABLE>
 
    Plus (+) or Minus (-): Plus and minus signs are used with a rating symbol to
indicate the relative position of a credit within the rating category. Plus and
minus signs, however, are not used in the "DDD", "DD", or "D" categories.
 
DESCRIPTION OF FITCH'S SHORT-TERM RATINGS
 
    Fitch's short-term ratings apply to debt obligations that are payable on
demand or have original maturities of up to three years, including commercial
paper, certificates of deposit, medium-term notes, and municipal and investment
notes.
 
    Although the credit analysis is similar to Fitch's bond rating analysis, the
investment grade short-term rating places greater emphasis than bond ratings on
the existence of liquidity necessary to meet the issuer's obligations in a
timely manner.
 
                                      II-8
<PAGE>
    Fitch short-term ratings are as follows:
 
<TABLE>
<S>    <C>
F-1+   Exceptionally Strong Credit Quality. Issues assigned this rating are regarded as
       having the strongest degree of assurance for timely payment.
F-1    Very Strong Credit Quality. Issues assigned this rating reflect an assurance of
       timely payment only slightly less in degree than issues rated "F-1+".
F-2    Good Credit Quality. Issues assigned this rating have a satisfactory degree of
       assurance for timely payment, but the margin of safety is not as great as for issues
       assigned "F-1+" and "F-1" ratings.
F-3    Fair Credit Quality. Issues carrying 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-4    Weak Credit Quality. Issues carrying this rating have characteristics suggesting a
       minimal degree of assurance for timely payment and are vulnerable to near-term
       adverse changes in financial 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.
INS    The symbol "INS" indicates that the rating is based on an insurance policy or
       financial guaranty issued by an insurance company.

ITEM 15. INDEMNIFICATION
 
    Section 2-418 of the General Corporation Law of the State of Maryland,
Article VI of the Acquiring Fund's Bylaws and the Investment Advisory Agreement
provide for indemnification.
 
    Insofar as indemnification for liabilities arising under the Securities Act
of 1933, as amended (the "Act"), may be provided to directors, officers and
controlling persons of the Acquiring Fund, pursuant to the foregoing provisions
or otherwise, the Acquiring Fund has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the Acquiring Fund of expenses incurred or paid by a director, officer or
controlling person of the Fund in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Acquiring Fund will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.
 
    Reference is made to Section 6 of the Purchase Agreement, a form of which is
filed as Exhibit (7)(a) hereto, for provisions relating to the indemnification
of the Underwriter.

Dear Sirs:
 
    We have acted as counsel for MuniAssets Fund, Inc., a Maryland corporation
(the "Fund"), in connection with the preparation and filing with the Securities
and Exchange Commission under the Securities Act of 1933, as amended (the
"Securities Act"), of a Registration Statement on Form N-14 (the "Registration
Statement") relating to the issuance by the Fund up to 7,000,000 shares of its
common stock, par value $0.10 per share (the "Shares").
 
    In so acting, we have examined and relied upon originals or copies,
certified or otherwise identified to our satisfaction, of such corporate
records, documents, certificates and other instruments as in our judgment are
necessary or appropriate to enable us to render the opinions expressed below. As
to matters governed by the laws of the State of Maryland, we have relied on the
opinion of Galland, Kharasch, Morse & Garfinkle, P.C., a copy of which is
attached hereto.
 
    Based upon the foregoing, and such examination of law as we have deemed
necessary, we are of the opinion that:

    1.   The Shares to be issued by the Fund have been duly authorized and,
when issued and delivered as contemplated in the Registration Statement,
will be validly issued, fully paid and nonassessable.

    2.   The statements set forth under the headings "The Reorganization -
Federal Income Tax Consequences of the Reorganization" and "Taxes" in the
Prospectus contained in the Registration Statement, insofar as such
statements constitute a summary of matters of law, are fair summaries of
the material provisions thereof and accurately present the information
called for with respect to such matters.
 
    We hereby consent to the filing of this opinion with the Securities and
Exchange Commission as an Exhibit to the Registration Statement. In giving this
consent, we do not admit that we are within the category of persons whose
consent is required under Section 7 of the Securities Act or rules and
regulations of the Securities and Exchange Commission thereunder.
 
                                          Very truly yours,



                                          /s/ Rogers & Wells

                    Re:  MuniAssets Fund, Inc.
                         ---------------------

          Ladies and Gentlemen:

               We have acted as Maryland counsel for MuniAssets Fund, Inc.,
          a Maryland corporation (the "Fund"), regarding issues of Maryland
          corporate law in connection with an Agreement and Plan of
          Reorganization between the Fund and MuniBond Income Fund, Inc.
          (the "Acquired Fund"), whereby the Fund would acquire
          substantially all of the assets, and assume substantially all of
          the liabilities, of the Acquired Fund, as described in a
          Registration Statement on Form N-14 (the "Registration
          Statement") relating to the issuance by the Fund of up to
          7,000,000 shares of its common stock, par value $0.10 per share
          (the "Shares").

               We have examined such documents as we have deemed necessary
          to render the opinion expressed herein and considered such
          questions of law as we have deemed appropriate.

               We have assumed, without independent verification, the
          genuineness of signatures, the authenticity of all documents
          submitted to us as originals, and the conformity with originals
          of all documents submitted to us as copies.

               The opinion set forth herein is in all respects subject to
          the following limitations:

               (a)  This opinion is strictly limited to the general
          corporation laws of the State of Maryland, and we express no
          opinion as to the tax, securities or "blue sky" laws of Maryland,
          to federal securities laws or to any other laws of any other
          jurisdiction or compliance therewith by any party.

               (b)  The Charter and By-Laws of the Fund require compliance
          with various provisions of the Investment Company Act of 1940. 
          We express no opinion with respect to such compliance.

               Based on the foregoing and subject to the qualifications set
          forth herein, it is our opinion that the Shares to be issued by
          the Fund are duly authorized and, when issued and delivered as
          contemplated in the Registration Statement, will be validly
          issued, fully paid and nonassessable.

               This opinion is delivered to you and is solely for the
          benefit and exclusive use of the Fund and its directors and
          officers.  Except that Rogers & Wells may rely on the foregoing
          opinion in rendering its opinion to you, and except pursuant to
          the consent given herein, this opinion may not be reproduced,
          duplicated, quoted or excerpted from or referred to, shown,
          disseminated or delivered to, or relied on by, any other party
          (including governmental agencies) for any reason without the
          written consent of the undersigned.

               We hereby consent to the filing of this opinion with the
          Securities and Exchange Commission as an exhibit to the
          Registration Statement.  In giving this consent, we do not admit
          that we are within the category of persons whose consent is
          required under Section 7 of the Securities Act of 1933, as
          amended, or rules or regulations of the Securities and Exchange
          Commission thereunder.


                                        Very truly yours,
