     This Joint Proxy Statement and Prospectus (this "Proxy Statement and
Prospectus") is furnished in connection with the solicitation of proxies on
behalf of the Boards of Directors of MuniYield Insured Fund, Inc., a Maryland
corporation ("Insured I"), and MuniYield Insured Fund II, Inc., a Maryland
corporation ("Insured II"), for use at Annual Meetings of Stockholders (the
"Meetings") called to approve or disapprove the proposed reorganization whereby
(i) Insured I will acquire all of the assets, and will assume all of the
liabilities, of Insured II, in exchange solely for an equal aggregate value of
newly-issued shares of Common Stock, par value $.10 per share, of Insured I
("Insured I Common Stock") and shares of two newly-created series of Auction
Market Preferred Stock ("AMPS") of Insured I, with a liquidation preference of

issued by Insured I; and (ii) Insured II will be deregistered and dissolved
(collectively, the "Reorganization"). Insured I and Insured II sometimes are
referred to herein collectively as the "Funds" and individually as a "Fund",
each as applicable and each as the context requires. This Proxy Statement and
Prospectus also is being furnished in connection with the election of a Board of
Directors of each Fund and the ratification of the selection of independent
auditors for each Fund.
                                                        (continued on next page)
                            ------------------------
 
THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
    EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION, NOR HAS THE
       SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES
         COMMISSION PASSED UPON THE ACCURACY OR ADEQUACY OF THIS
            PROXY STATEMENT AND PROSPECTUS. ANY REPRESENTATION TO
               THE CONTRARY IS A CRIMINAL OFFENSE.
                            ------------------------
 
     This Proxy Statement and Prospectus serves as a prospectus of Insured I
under the Securities Act of 1933, as amended (the "Securities Act"), in
connection with the issuance of Insured I Common Stock, Insured I Series F AMPS
and Insured I Series G AMPS in the Reorganization.
 
     This Proxy Statement and Prospectus sets forth concisely the information
about Insured I and Insured II that stockholders of Insured I and Insured II
should know before considering the Reorganization and should be retained for
future reference. Insured I and Insured II have authorized the solicitation of
proxies in connection with the Reorganization solely on the basis of this Proxy
Statement and Prospectus and the accompanying documents.
 
     The address of the principal executive offices of both Insured I and
Insured II is 800 Scudders Mill Road, Plainsboro, New Jersey 08536, and the
telephone number is (609) 282-2800.
                            ------------------------
 
    THE DATE OF THIS PROXY STATEMENT AND PROSPECTUS IS               , 1996.

     The aggregate net asset value of the Insured I Common Stock to be issued to
Insured II and thereafter distributed to the holders of shares of Common Stock,
par value $.10 per share, of Insured II ("Insured II Common Stock") will equal
the aggregate net asset value of the shares of Insured II Common Stock on the
date of the Reorganization. Similarly, it is intended that the aggregate
liquidation preference and value of the Insured I Series F AMPS to be issued to
Insured II and thereafter distributed to the holders of shares of AMPS of
Insured II, with a liquidation preference of $25,000 per share plus an amount
equal to accumulated but unpaid dividends thereon (whether or not earned or
declared), designated Series A AMPS ("Insured II Series A AMPS"), will equal the
aggregate liquidation preference and value of the Insured II Series A AMPS on
the date of the Reorganization, and that the aggregate liquidation preference
and value of the Insured I Series G AMPS to be issued to Insured II and
thereafter distributed to the holders of shares of AMPS of Insured II, with a
liquidation preference of $25,000 per share plus an amount equal to accumulated
but unpaid dividends thereon (whether or not earned or declared), designated
Series B AMPS ("Insured II Series B AMPS" and, together with the Insured II
Series A AMPS, the "Insured II AMPS"), will equal the aggregate liquidation
preference and value of the Insured II Series B AMPS on the date of the
Reorganization. As soon as practicable after the receipt by Insured I of all of
Insured II's assets and the assumption by Insured I of all of Insured II's
liabilities, Insured II will distribute Insured I Common Stock, Insured I Series
F AMPS and Insured I Series G AMPS to Insured II's stockholders as described
under "The Reorganization". Thereafter, Insured II will terminate its
registration under the Investment Company Act of 1940, as amended (the
"Investment Company Act"), and will liquidate and dissolve in accordance with
the laws of the State of Maryland.
 
     Both Insured I and Insured II are non-diversified, leveraged, closed-end
management investment companies with virtually identical investment objectives.
Both Insured I and Insured II seek to provide stockholders with as high a level
of current income exempt from Federal income taxes as is consistent with their
respective investment policies and prudent investment management. Insured I and
Insured II seek to achieve their respective investment objectives by investing
primarily in a portfolio of long-term, investment grade municipal obligations
the interest on which, in the opinion of bond counsel to the issuer, is exempt
from Federal income taxes ("Municipal Bonds"). There can be no assurance that
after the Reorganization the surviving fund will achieve the investment
objective of either Insured I or Insured II.
 
     Insured I Common Stock and Insured II Common Stock are listed on the New
York Stock Exchange (the "NYSE") under the symbols "MYI" and "MTI",
respectively. Subsequent to the Reorganization, shares of Insured I Common Stock
will continue to be listed on the NYSE under the symbol "MYI". Reports, proxy
materials and other information concerning either Fund may be inspected at the
offices of the NYSE, 11 Wall Street, New York, New York 10005.

                                  INTRODUCTION
 
     This Proxy Statement and Prospectus is furnished in connection with the
solicitation of proxies on behalf of the Boards of Directors of Insured I and
Insured II for use at the Meetings to be held at the offices of Merrill Lynch
Asset Management, L.P. ("MLAM"), 800 Scudders Mill Road, Plainsboro, New Jersey
on September 9, 1996, at 10:45 A.M., New York time (for Insured I) and 11:00
A.M., New York time (for Insured II). The mailing address for both Insured I and
Insured II is P.O. Box 9011, Princeton, New Jersey 08543-9011. The approximate
mailing date of this Proxy Statement and Prospectus is                     ,
1996.
 
     Any person giving a proxy may revoke it at any time prior to its exercise
by executing a superseding proxy, by giving written notice of the revocation to
the Secretary of Insured I or Insured II, as applicable, at the address
indicated above or by voting in person at the appropriate Meeting. All properly
executed proxies received prior to the Meetings will be voted at the Meetings in
accordance with the instructions marked thereon or otherwise as provided
therein. Unless instructions to the contrary are marked, proxies will be voted
"FOR" each of the following proposals: (1) to approve the Agreement and Plan of
Reorganization between Insured I and Insured II (the "Agreement and Plan of
Reorganization"); (2) to elect a Board of Directors of each Fund to serve for
the ensuing year; (3) for the stockholders of Insured I only: (a) in the event
that proposal 1 is approved by the requisite number of stockholders of each Fund
and the Reorganization takes place prior to October 31, 1996, to consider and
act upon a proposal to ratify the selection of Ernst & Young LLP to serve as
independent auditors of the combined fund for the fiscal year ending October 31,
1996; and (b) in the event that proposal 1 is not approved by the requisite
number of stockholders of each Fund or the Reorganization does not take place
prior to October 31, 1996, to consider and act upon a proposal to ratify the
selection of Deloitte & Touche LLP to serve as independent auditors of Insured I
for the current fiscal year ending October 31, 1996; and (4) for the
stockholders of Insured II only: to ratify the selection of Ernst & Young LLP as
the independent auditors of Insured II for the current fiscal year ending
October 31, 1996.
 
     With respect to proposal 1, approval of the Agreement and Plan of
Reorganization will require the affirmative vote of stockholders representing a
majority of the outstanding shares of Insured I Common Stock and AMPS of Insured
I, designated Series A, Series B, Series C, Series D and Series E, each with a
liquidation preference of $25,000 per share plus an amount equal to accumulated
but unpaid dividends thereon (whether or not earned or declared) (collectively,
the "Insured I AMPS"), voting together as a single class, and a majority of the
outstanding shares of Insured I AMPS, voting separately as a class, as well as
the affirmative vote of stockholders representing a majority of the outstanding
shares of Insured II Common Stock and Insured II AMPS, voting together as a
single class, and a majority of the outstanding shares of Insured II AMPS,
voting separately as a class.
 
     With respect to proposal 2, holders of shares of Insured I AMPS are
entitled to elect two Directors of Insured I and holders of shares of Insured I
Common Stock and Insured I AMPS, voting together as a single class, are entitled
to elect the remaining Directors of Insured I; similarly, holders of shares of
Insured II AMPS are entitled to elect two Directors of Insured II and holders of
shares of Insured II Common Stock and Insured II AMPS, voting together as a
single class, are entitled to elect the remaining Directors of Insured II.
Assuming a quorum is present, (x) election of the two Directors of Insured I or
Insured II, as the case may be, to be elected by the holders of that Fund's
AMPS, voting separately as a class, will require the affirmative vote of a
majority of the votes cast by the holders of the Insured I AMPS or Insured II
AMPS, respectively, represented at the Meetings and entitled to vote; and (y)
election of the remaining Directors of Insured I or
 
                                        5
<PAGE>   10
 
Insured II, as the case may be, will require the affirmative vote of a majority
of the votes cast by the holders of shares of their respective Common Stock and
AMPS, represented at the Meetings and entitled to vote, voting together as a
single class.
 
     With respect to proposal 3(a), (i) approval of the ratification of the
selection of Ernst & Young LLP as the independent auditors of the combined fund
will require the affirmative vote of a majority of the votes cast by the holders
of shares of Insured I Common Stock and Insured I AMPS represented at the
Meetings and entitled to vote, voting together as a single class; and with
respect to proposal 3(b), approval of the ratification of the selection of
Deloitte & Touche LLP as the independent auditors of Insured I will require the
affirmative vote of a majority of the votes cast by the holders of shares of
Insured I Common Stock and Insured I AMPS represented at the Meetings and
entitled to vote, voting together as a single class.
 
     With respect to proposal 4, approval of the ratification of the selection
of Ernst & Young LLP as the independent auditors of Insured II will require the
affirmative vote of a majority of the votes cast by the holders of shares of
Insured II Common Stock and Insured II AMPS represented at the Meetings and
entitled to vote, voting together as a single class.
 
     The Boards of Directors of Insured I and Insured II have fixed the close of
business on July 15, 1996 as the record date (the "Record Date") for the
determination of stockholders entitled to notice of, and to vote at, the
Meetings or any adjournment thereof. Stockholders on the Record Date will be
entitled to one vote for each share held, with no shares having cumulative
voting rights. As of the Record Date, there were issued and outstanding
45,187,339 shares of Insured I Common Stock, 12,800 shares of Insured I AMPS in
five series, 16,420,827 shares of Insured II Common Stock and 4,800 shares of
Insured II AMPS in two series. To the knowledge of the management of each of
Insured I and Insured II, no person owned beneficially more than 5% of the
respective outstanding shares of either class of capital stock of Insured I or
Insured II at the Record Date.
 
     The Boards of Directors of Insured I and Insured II know of no business
other than that discussed in proposals 1, 2, 3 and 4 above which will be
presented for consideration at the Meetings. If any other matter is properly
presented, it is the intention of the persons named in the enclosed proxy to
vote in accordance with their best judgment.
 
                               THE REORGANIZATION
 
SUMMARY
 
     The following is a summary of certain information contained elsewhere in
this Proxy Statement and Prospectus and is qualified in its entirety by
reference to the more complete information contained herein and in the Agreement
and Plan of Reorganization, attached hereto as Exhibit I.
 
     In this Proxy Statement and Prospectus, the term "Reorganization" refers
collectively to (i) the acquisition of all of the assets and the assumption of
all of the liabilities of Insured II by Insured I and the subsequent
distribution of Insured I Common Stock, Insured I Series F AMPS and Insured I
Series G AMPS to the holders of Insured II Common Stock, Insured II Series A
AMPS and Insured II Series B AMPS, respectively, and (ii) the subsequent
deregistration and dissolution of Insured II.
 
                                        6

     At a meeting of the Board of Directors of Insured I held on June 18, 1996,
and at a meeting of the Board of Directors of Insured II held on May 3, 1996,
the Boards of Directors of Insured I and Insured II unanimously approved a
proposal that Insured I acquire all of the assets, and assume all of the
liabilities, of Insured II in exchange solely for Insured I Common Stock,
Insured I Series F AMPS and Insured I Series G AMPS to be issued to Insured II
and thereafter distributed to the stockholders of Insured II. Subject to
obtaining the necessary approvals from the Insured I and Insured II
stockholders, the Board of Directors of Insured II deemed advisable the
deregistration of Insured II under the Investment Company Act and its
dissolution under the laws of the State of Maryland.
 
     Both Insured I and Insured II seek to provide stockholders with as high a
level of current income exempt from Federal income taxes as is consistent with
their respective investment policies and prudent investment management. Both
Insured I and Insured II seek to achieve their investment objectives by
investing primarily in a portfolio of Municipal Bonds. Under normal
circumstances, at least 80% of each Fund's total assets will be invested in
Municipal Bonds with remaining maturities of one year or more which are covered
by insurance guaranteeing the timely payment of principal at maturity and
interest.
 
     Insured I and Insured II are both non-diversified, leveraged, closed-end
management investment companies registered under the Investment Company Act. If
the Insured I and Insured II stockholders approve the Reorganization, Insured I
Common Stock, Insured I Series F AMPS and Insured I Series G AMPS will be issued
to Insured II in exchange for the assets of Insured I and thereafter Insured II
will distribute these shares to its stockholders as provided in the Agreement
and Plan of Reorganization. After the Reorganization, Insured II will terminate
its registration under the Investment Company Act and its incorporation under
Maryland law.
 
     Based upon their evaluation of all relevant information, the Directors of
Insured I and Insured II have determined that the Reorganization will
potentially benefit the holders of Common Stock of both Insured I and Insured
II. Specifically, after the Reorganization, Insured II stockholders will remain
invested in a closed-end fund that has an investment objective and policies
virtually identical to those of Insured II and which utilizes the same
management personnel. In addition, it is anticipated that both Insured I and
Insured II common stockholders will be subject to a reduced overall operating
expense ratio based on the combined assets of the surviving fund after the
Reorganization. It is not anticipated that the Reorganization will directly
benefit the holders of shares of Insured I AMPS or Insured II AMPS; however, the
Reorganization will not adversely affect the holders of shares of AMPS of either
Fund and the expenses of the Reorganization will not be borne by the holders of
shares of AMPS of either Fund.
 
     In deciding to recommend the Reorganization, the Boards of Directors of
Insured I and Insured II took into account the investment objective and policies
of both Insured I and Insured II, the expenses incurred both due to the
Reorganization and on an ongoing basis by the new and existing stockholders of
Insured I and the potential benefits, including economies of scale, to the
holders of Common Stock and AMPS of Insured I and Insured II as a result of the
Reorganization. The Boards of Directors of Insured I and Insured II, including
all of the Directors who are not "interested persons", as defined in the
Investment Company Act, of Insured I or Insured II, have determined that the
Reorganization is in the best interests of each of the Funds and of the holders
of Common Stock and AMPS of Insured I and Insured II and that the interests of
such stockholders will not be diluted as a result of effecting the
Reorganization.

<PAGE>   12
 
     If all of the requisite approvals are obtained, it is anticipated that the
Reorganization will occur as soon as practicable after such approval, provided
that the Funds have obtained prior to that time a favorable private letter
ruling from the Internal Revenue Service (the "IRS") concerning the tax
consequences of the Reorganization as set forth in the Agreement and Plan of
Reorganization. Under the Agreement and Plan of Reorganization, however, the
Board of Directors of either Insured I or Insured II may cause the
Reorganization to be postponed or abandoned should either Board determine that
it is in the best interests of the stockholders of either Insured I or Insured
II, respectively, to do so. The Agreement and Plan of Reorganization may be
terminated, and the Reorganization abandoned, whether before or after approval
by the Funds' stockholders, at any time prior to the Exchange Date (as defined
below), (i) by mutual consent of the Boards of Directors of Insured I and
Insured II; (ii) by the Board of Directors of Insured I if any condition to
Insured I's obligations has not been fulfilled or waived by such Board; or (iii)
by the Board of Directors of Insured II if any condition to Insured II's
obligations has not been fulfilled or waived by such Board.

(a) No information is presented with respect to AMPS because neither a Fund's
    expenses nor expenses of the Reorganization will be borne by the holders of
    AMPS of either Fund. Generally AMPS are sold at a fixed liquidation
    preference of $25,000 per share and investment return is set at an auction.
 
(b) Sales load charged in the Fund's initial offering, subject to reductions for
    bulk purchases. Shares of Common Stock purchased on the secondary market are
    not subject to sales loads, but may be subject to brokerage commissions or
    other charges.
 
(c) No sales load will be charged on the issuance of shares in the
    Reorganization. Shares of Common Stock are not available for purchase from
    the Funds but may be purchased through a broker-dealer subject to
    individually negotiated commission rates.
 
(d) The actual annual fund operating expenses were derived from each Fund's
    shareholder report dated as of April 30, 1996. The pro forma annual
    operating expenses for the combined fund are projections for a 12-month
    period.

     The foregoing Fee Table is intended to assist investors in understanding
the costs and expenses that an Insured I or Insured II common stockholder will
bear directly or indirectly as compared to the costs and expenses that would be
borne by such investors taking into account the Reorganization. The Example set
forth above assumes that shares of Common Stock were purchased in the initial
offerings and the reinvestment of all dividends and distributions and utilizes a

BUSINESS OF INSURED I......  Insured I was incorporated under the laws of the
                             State of Maryland on January 13, 1992 and commenced
                             operations on March 27, 1992. Like Insured II,
                             Insured I is a non-diversified, leveraged,
                             closed-end management investment company whose
                             investment objective is to provide stockholders
                             with as high a level of current income exempt from
                             Federal income taxes as is consistent with its
                             investment policies and prudent investment
                             management. Furthermore, like Insured II, Insured I
                             seeks to achieve its investment objective by
                             investing primarily in a portfolio of Municipal
                             Bonds. See "Comparison of the Funds -- Investment
                             Objectives and Policies".
 
                             Like Insured II, Insured I has outstanding both
                             Common Stock and AMPS. As of April 30, 1996,
                             Insured I had net assets of $999,007,576.
 
BUSINESS OF INSURED II.....  Insured II was incorporated under the laws of the
                             State of Maryland on September 2, 1992 and
                             commenced operations on October 30, 1992. Like
                             Insured I, Insured II is a non-diversified,
                             leveraged, closed-end management investment company
                             whose investment objective is to

                             provide stockholders with as high a level of
                             current income exempt from Federal income taxes as
                             is consistent with its investment policies and
                             prudent investment management. Furthermore, like
                             Insured I, Insured II seeks to achieve its
                             investment objective by investing primarily in a
                             portfolio of Municipal Bonds.
 
                             Like Insured I, Insured II has outstanding both
                             Common Stock and AMPS. As of April 30, 1996,
                             Insured II had net assets of $365,558,557.
 
COMPARISON OF THE FUNDS....  Investment Objectives and Policies. Insured I and
                             Insured II have virtually identical investment
                             objectives and policies. Both Funds seek to pay
                             interest exempt from Federal income taxes and seek
                             to maintain as much of their respective portfolios
                             invested in Municipal Bonds as possible. As of
                             April 30, 1996, 98% of Insured I's net assets and
                             98% of Insured II's net assets were invested in
                             Municipal Bonds. The same investment restrictions
                             apply to both Insured I and Insured II. See
                             "Comparison of the Funds -- Investment Objective
                             and Policies".
 
                             Capital Stock. Insured I and Insured II each has
                             outstanding both Common Stock and several series of
                             AMPS. Like Insured II Common Stock, Insured I
                             Common Stock is traded on the NYSE. As of April 30,
                             1996, the net asset value per share of the Insured
                             I Common Stock was $15.03 and the market price per
                             share was $13.75, and as of the same date, the net
                             asset value per share of the Insured II Common
                             Stock was $14.95 and the market price per share was
                             $13.375. Insured I AMPS and Insured II AMPS have
                             liquidation preferences of $25,000 per share and
                             are sold principally at auctions. See "Comparison
                             of the Funds -- Capital Stock".
 
                             Auctions generally have been held and will be held
                             every 28 days in the case of the Insured I Series A
                             AMPS, Series B AMPS, Series C AMPS and Series D
                             AMPS and every seven days in the case of the
                             Insured I Series E AMPS unless Insured I elects,
                             subject to certain limitations, to have a special
                             dividend period. As of the auction held on May 15,
                             1996, the dividend rate on the Insured I Series A

                             E AMPS was 3.64%.
 
                             Similarly, auctions generally have been held and
                             will be held every 28 days in the case of the
                             Insured II Series A AMPS and every seven days in
                             the case of the Insured II Series B AMPS unless
                             Insured II elects, subject to certain limitations,
                             to have a special dividend period. In

                             connection with the auction held on June 10, 1996,
                             Insured II elected a special dividend period on the
                             Insured II Series A AMPS which ends February 3,
                             1997 and the dividend rate during such special
                             dividend period is 3.68%. The Insured I Series F
                             AMPS to be issued in the Reorganization for the
                             Insured II Series A AMPS will have an initial
                             dividend period ending February 3, 1997 and an
                             initial dividend rate of 3.68%. As of the auction
                             held on May 24, 1996, the dividend rate on the
                             Insured II Series B AMPS was 3.625%.
 
                             Advisory Fees. The investment adviser for both
                             Insured I and Insured II is Fund Asset Management,
                             L.P. ("FAM"). FAM is an affiliate of MLAM, and both
                             FAM and MLAM are owned and controlled by Merrill
                             Lynch & Co., Inc. ("ML & Co."). The principal
                             business address of FAM is 800 Scudders Mill Road,
                             Plainsboro, New Jersey 08536. MLAM or FAM acts as

                             individuals and institutions.
 
                             FAM is responsible for the management of each
                             Fund's investment portfolio and for providing
                             administrative services to each Fund. The same
                             personnel manage the portfolios of both Insured I
                             and Insured II. William Bock serves as the
                             portfolio manager for both Funds.
 
                             Pursuant to separate investment advisory agreements
                             between each Fund and FAM, each Fund pays FAM a
                             monthly fee at the annual rate of 0.50% of such
                             Fund's average weekly net assets. Subsequent to the
                             Reorganization, FAM will continue to receive
                             compensation at the rate of 0.50% of the average

                             Overall Expense Ratio. As of April 30, 1996, the
                             overall annualized operating expense ratio for
                             Insured I was 0.64%, based on average net assets of
                             approximately $1.0 billion including AMPS, and
                             0.93%, based on average net assets of approximately
                             $706.5 million excluding AMPS, and the overall
                             annualized expense ratio for Insured II was 0.67%,
                             based on average net assets of approximately $374.9
                             million including AMPS, and 0.98%, based on average
                             net assets of approximately $254.9 million
                             excluding AMPS. If the Reorganization had taken
                             place on April 30, 1996, the overall operating
                             expense ratio for the combined fund on a pro forma
                             basis would have been 0.62%, based on average net
                             assets of approximately $1.4 billion including
                             AMPS, and 0.90%, based on average net assets of
                             approximately $961.5 million excluding AMPS.
 
                             Purchases and Sales of Common Stock and
                             AMPS. Purchase and sale procedures for both Insured
                             I Common Stock and Insured II Common Stock are
                             identical, and investors typically purchase and
                             sell shares of Common Stock of such Funds through a
                             registered broker-dealer on the NYSE, thereby
                             incurring a brokerage commission set by the broker-
                             dealer. Alternatively, investors may purchase or
                             sell shares of Common Stock of such Funds through
                             privately negotiated transactions with existing
                             stockholders.
 
                             Purchase and sale procedures for Insured I AMPS and
                             Insured II AMPS also are identical. Such AMPS
                             generally are purchased and sold at separate
                             auctions conducted on a regular basis by IBJ
                             Schroder Bank and Trust Company, as the auction
                             agent for each Fund's AMPS (the "Auction Agent").
                             Unless otherwise permitted by the Funds, existing
                             and potential holders of AMPS only may participate
                             in auctions through their broker-dealers.
                             Broker-dealers submit the orders of their
                             respective customers who are existing and potential
                             holders of AMPS to the Auction Agent. On or prior
                             to each auction date for the AMPS (the business day
                             next preceding the first day of each dividend
                             period), each holder may submit orders to buy, sell
                             or hold AMPS to its broker-dealer. Outside of these
                             auctions, shares of Insured I AMPS or Insured II
                             AMPS may be purchased or sold through
                             broker-dealers for the AMPS in a secondary trading
                             market maintained by the broker-dealers. However,
                             there can be no assurance that a secondary market
                             actually will be developed and maintained by the
                             broker-dealers for the AMPS of either Fund.
 
                             Ratings of AMPS. The Insured I AMPS and the Insured
                             II AMPS have each been assigned a rating of AAA
                             from Standard & Poor's Ratings Group ("S&P") and
                             "aaa" from Moody's Investors Service, Inc.
                             ("Moody's"). See "Comparison of the Funds -- Rating
                             Agency Guidelines".

                             Portfolio Insurance. The policies are the same for
                             each Fund with respect to obtaining insurance for
                             portfolio securities. Under normal circumstances,
                             at least 80% of each Fund's assets will be invested
                             in Municipal Bonds either (i) insured under an
                             insurance policy purchased by the Fund or (ii)
                             insured under an insurance policy obtained by the
                             issuer thereof or any other party. See "Comparison
                             of the Funds -- Investment Objective and
                             Policies -- Portfolio Insurance".
 
                             Portfolio Transactions. The portfolio transactions
                             in which Insured I and Insured II may engage are
                             identical, as are the procedures for such
                             transactions. See "Comparison of the
                             Funds -- Portfolio Transactions".
 
                             Dividends and Distributions. The methods of
                             dividend payment and distributions are identical
                             for Insured I and Insured II, both with respect to
                             the Common Stock and the AMPS of each Fund. See
                             "Comparison of the Funds -- Dividends and
                             Distributions".
 
                             Net Asset Value. The net asset value per share of
                             Common Stock of each Fund is determined as of 15
                             minutes after the close of business on the NYSE
                             (generally, 4:00 P.M., New York time) on each day
                             during which the NYSE is open for trading. For
                             purposes of determining the net asset value of a
                             share of Common Stock of each Fund, the value of
                             the securities held by the Fund plus any cash or
                             other assets (including interest accrued but not
                             yet received) minus all liabilities (including
                             accrued expenses) and the aggregate liquidation
                             value of the outstanding shares of AMPS of the Fund
                             is divided by the total number of shares of Common
                             Stock of the Fund outstanding at such time.
                             Expenses, including the fees payable to FAM, are
                             accrued daily. See "Comparison of the Funds -- Net
                             Asset Value".
 
                             Voting Rights. The corresponding voting rights of
                             the holders of shares of Insured I Common Stock and
                             Insured II Common Stock are identical. Similarly,
                             the corresponding voting rights of the holders of
                             shares of Insured I AMPS and Insured II AMPS are
                             identical. See "Comparison of the Funds -- Capital
                             Stock".
 
                             Stockholder Services. An automatic dividend
                             reinvestment plan is available both to the holders
                             of shares of Insured I Common Stock and the holders
                             of shares of Insured II Common Stock. The plans are
                             identical for the two Funds. See "Comparison of the
                             Funds -- Automatic Dividend Reinvestment Plan".
                             Other stockholder services, including the provision
                             of annual and semi-annual reports, are the same for
                             the two Funds.

TAX CONSIDERATIONS.........  Insured I and Insured II have jointly requested a
                             private letter ruling from the IRS with respect to
                             the Reorganization to the effect that, among other
                             things, neither Insured I nor Insured II will
                             recognize gain or loss on the transaction and
                             Insured II stockholders will not recognize gain or
                             loss on the exchange of their Insured II shares for
                             shares of Insured I Common Stock (except to the
                             extent that an Insured II Common Stockholder
                             receives cash representing an interest in less than
                             a full share of Insured I Common Stock in the
                             Reorganization), Insured I Series F AMPS or Insured
                             I Series G AMPS. The consummation of the
                             Reorganization is subject to the receipt of such
                             ruling. The Reorganization will not affect the
                             status of Insured I as a regulated investment
                             company (a "RIC") under the Internal Revenue Code
                             of 1986, as amended (the "Code"). Insured II will
                             liquidate pursuant to the Reorganization. See "The
                             Reorganization -- Tax Consequences of the
                             Reorganization".
 
RISK FACTORS AND SPECIAL CONSIDERATIONS
 
     Since both Insured I and Insured II invest primarily in a portfolio of
Municipal Bonds, any risks inherent in such investments are equally applicable
to both Funds and will be similarly pertinent to the combined fund after the
Reorganization. It is expected that the Reorganization itself will not adversely
affect the rights of holders of shares of Common Stock or AMPS of either Fund or
create additional risks.

EFFECTS OF LEVERAGE
 
     Utilization of leverage, through the issuance of AMPS, involves certain
risks to holders of Insured I Common Stock and Insured II Common Stock. For
example, each Fund's issuance of AMPS may result in higher volatility of the net
asset value of its Common Stock and potentially more volatility in the market
value of its Common Stock. In addition, fluctuations in the short-term and
medium-term dividend rates on, and the amount of taxable income allocable to,
the AMPS affect the yield to holders of Common Stock. So long as each Fund,
taking into account the costs associated with its AMPS and the Fund's operating
expenses, is able to realize a higher net return on its investment portfolio
than the then-current dividend rate on the AMPS, the effect of leverage is to
cause holders of the Fund's Common Stock to realize a higher current rate of
return than if the Fund were not leveraged. Similarly, since a pro rata portion
of each Fund's net realized capital gains on its investment assets generally is
payable to holders of the Fund's Common Stock, if increased net capital gains
are realized by the Fund because of increased capital for investment, the effect
of leverage will be to increase the amount of such gains distributed to holders
of the Fund's Common Stock. However, short-term, medium-term and long-term
interest rates change from time to time as does their relationship to each other
(i.e., the slope of the yield curve) depending upon such factors as supply and
demand forces, monetary and tax policies and investor expectations. Changes in
such factors could cause the relationship between short-term, medium-term and
long-term rates to change (i.e., to flatten or to invert the slope of the yield
curve) so that short-term and medium-term rates may increase substantially
relative to the long-term obligations in which each Fund may be invested. To the
extent that the current dividend rate on the AMPS approaches the net return on a
Fund's investment portfolio, the benefit of leverage to holders of Common Stock
is reduced, and if the current dividend rate on the AMPS were to exceed the net
return on a Fund's portfolio, the Fund's leveraged capital structure would
result in a lower rate of return to holders of Common Stock than if the Fund
were not leveraged. Similarly, since both the costs associated with the issuance
of AMPS and any decline in the value of a Fund's investments (including
investments purchased with the proceeds from any AMPS offering) are borne
entirely by holders of the Fund's Common Stock, the effect of leverage in a
declining market would result in a greater decrease in net asset value to
holders of Common Stock than if the Fund were not leveraged. Such decrease in
net asset value likely would be reflected in a greater decline in the market
price for shares of Common Stock.
 
     In an extreme case, a decline in net asset value could affect each Fund's
ability to pay dividends on its Common Stock. Failure to make such dividend
payments could adversely affect the Fund's qualification for the special tax
treatment afforded RICs under the Code. See "The Reorganization -- Tax
Consequences of the Reorganization". Each Fund intends, however, to take all
measures necessary to continue to make Common Stock dividend payments. If a
Fund's current investment income were not sufficient to meet dividend
requirements on either the Common Stock or the AMPS, it could be necessary for
the Fund to liquidate certain of its investments. In addition, each Fund has the
authority to redeem its AMPS for any reason and may redeem all or part of its
AMPS if (i) the Fund anticipates that its leveraged capital structure will
result in a lower rate of return for any significant amount of time to holders
of the Common Stock than that obtainable if the Common Stock were unleveraged or
(ii) the asset coverage (as defined in the Investment Company Act) for the AMPS
declines below 200% or the Fund fails to satisfy the guidelines specified by
Moody's and S&P in connection with their respective rating of the AMPS.
Redemption of the AMPS or insufficient investment income to make dividend
payments may reduce the net asset value of the Common Stock and require the Fund
to liquidate a portion of its investments at a time when it may be
disadvantageous, in the absence of such extraordinary circumstances, to do so.

PORTFOLIO MANAGEMENT
 
     The portfolio management strategies of Insured I and Insured II are the
same. In the event of an increase in short-term or medium-term rates or other
change in market conditions to the point where a Fund's leverage could adversely
affect holders of Common Stock as noted above, or in anticipation of such
changes, each Fund may attempt to shorten the average maturity of its investment
portfolio, which would tend to offset the negative impact of leverage on holders
of its Common Stock. Each Fund also may attempt to reduce the degree to which it
is leveraged by redeeming AMPS pursuant to the provisions of the Fund's Articles
Supplementary establishing the rights and preferences of the AMPS or otherwise
purchasing shares of AMPS. Purchases and sales or redemptions of AMPS, whether
on the open market or in negotiated transactions, are subject to limitations
under the Investment Company Act. If market conditions subsequently change, each
Fund may sell previously unissued shares of AMPS or shares of AMPS that the Fund
previously issued but later repurchased or redeemed.
 
RATINGS CONSIDERATIONS
 
     Insured I and Insured II have received ratings of their AMPS of AAA from
S&P and "aaa" from Moody's. In order to maintain these ratings, the Funds are
required to maintain portfolio holdings meeting specified guidelines of such
rating agencies. These guidelines may impose asset coverage requirements that
are more stringent than those imposed by the Investment Company Act.
 
     As described by Moody's and S&P, a preferred stock rating is an assessment
of the capacity and willingness of an issuer to pay preferred stock obligations.
The ratings of the AMPS are not recommendations to purchase, hold or sell shares
of AMPS, inasmuch as the ratings do not comment as to market price or
suitability for a particular investor, nor do the rating agency guidelines
address the likelihood that a holder of shares of AMPS will be able to sell such
shares in an auction. The ratings are based on current information furnished to
Moody's and S&P by the Funds and FAM and information obtained from other
sources. The ratings may be changed, suspended or withdrawn as a result of
changes in, or the unavailability of, such information. Neither the Insured I
Common Stock nor the Insured II Common Stock has been rated by a nationally
recognized statistical rating organization.
 
     The Board of Directors of each of Insured I and Insured II, as the case may
be, without stockholder approval, may amend, alter or repeal certain definitions
or restrictions which have been adopted by the Fund pursuant to the rating
agency guidelines, in the event the Fund receives confirmation from the rating
agencies that any such amendment, alteration or repeal would not impair the
ratings then assigned to shares of AMPS.

       As indicated in the tables above, since November 1, 1993 the Insured I
Common Stock and the Insured II Common Stock generally have traded at market
prices that represent a discount to net asset value. Since November 1, 1993,
share prices for Insured I Common Stock have fluctuated between a maximum
premium of 0.12% and a maximum discount of (17.56%) and share prices for Insured
II Common Stock have fluctuated between a maximum premium of 0.25% and a maximum
discount of (17.97%). 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 surviving fund will trade at a premium or discount to net asset
value following the Reorganization, or what the extent of any such premium or
discount might be.
 
INVESTMENT OBJECTIVE AND POLICIES
 
     The structure, organization and investment policies of Insured I and
Insured II are virtually identical, with the minor differences between the two
Funds set forth below. Each Fund seeks as a fundamental investment objective as
high a level of current income exempt from Federal income taxes as is consistent
with the Fund's investment policies and prudent investment management.
 
     The investment objective and policies of Insured I and Insured II are
identical. Each Fund seeks to achieve its investment objective by investing
primarily in a portfolio of Municipal Bonds. The investment objective of each
Fund is a fundamental policy that may not be changed without a vote of a
majority of the Fund's outstanding voting securities. Under normal
circumstances, at least 80% of each Fund's total assets will be invested in
Municipal Bonds with remaining maturities of one year or more which are covered
by insurance guaranteeing the timely payment of principal at maturity and
interest. At times, each Fund may seek to hedge its portfolio through the use of
futures and options transactions to reduce volatility in the net asset value of
its shares of Common Stock.
 
     Ordinarily, neither Fund intends to realize significant investment income
not exempt from Federal income taxes. Each Fund seeks to invest substantially
all of its total assets in Municipal Bonds except at times when, in the judgment
of FAM, Municipal Bonds of sufficient quality and quantity are unavailable for
investment by the Fund. Each Fund may invest in certain tax-exempt securities
classified as "private activity bonds" (in general, bonds that benefit
non-governmental entities) that may subject certain investors in the Fund to an
alternative minimum tax. Neither Fund will invest more than 25% of its total
assets (taken at market value) in Municipal Bonds whose issuers are located in
the same state.
 
     The investment grade Municipal Bonds in which each Fund invests are those
Municipal Bonds rated at the date of purchase within the four highest rating
categories of S&P, Moody's or Fitch Investors Service, Inc. ("Fitch") or, if
unrated, are considered to be of comparable quality by FAM. In the case of
long-term debt, the investment grade rating categories are AAA through BBB- for
S&P, Aaa through Baa3 for Moody's and AAA through BBB- for Fitch. In the case of
short-term notes, the investment grade rating categories are SP-1 through SP-3
for S&P, MIG-1 through MIG-4 for Moody's and F-1+ through F-4 for Fitch. In the
case of tax-exempt commercial paper, the investment grade rating categories are
A through A-3 for S&P, Prime-1 through Prime-3 for Moody's and F-l+ through F-4
for Fitch. Obligations ranked in the fourth highest rating category assigned
long-term debt or in an equivalent short-term rating category (BBB, SP-3 and A-3
for S&P; Baa, MIG-4 and Prime-3 for Moody's; and BBB, F-3 and F-4 for Fitch),
while considered "investment grade," may have certain speculative
characteristics. In assessing the quality of Municipal Bonds with respect to the
foregoing requirements, FAM takes into account the portfolio insurance as well
as the nature of any letters of credit or similar credit enhancement to which
particular Municipal Bonds are entitled and the
 
                                       22
<PAGE>   27
 
creditworthiness of the insurance company or other financial institution which
provided such credit enhancement. See Exhibit II -- "Ratings of Municipal Bonds
and Commercial Paper" and Exhibit III -- "Portfolio Insurance".
 
     In the case of Insured II only, if Municipal Bonds are covered by insurance
policies issued by insurers whose claims-paying ability is rated AAA by S&P or
Aaa by Moody's, FAM may consider such Municipal Bonds to be equivalent to AAA or
Aaa rated securities, as the case may be, even though such Municipal Bonds would
generally be assigned a lower rating if the rating were based primarily upon the
credit characteristics of the issuers without regard to the insurance feature.
The insured Municipal Bonds must also comply with the standards applied by the
insurance carriers in determining eligibility for portfolio insurance.
 
     Insured I and Insured II may invest in variable rate demand obligations
("VRDOs") and VRDOs in the form of participation interests ("Participating
VRDOs") in variable rate tax-exempt obligations held by a financial institution,
typically a commercial bank. The VRDOs in which each Fund may invest are
tax-exempt obligations (in the opinion of counsel to the issuer) which contain a
floating or variable interest rate adjustment formula and an unconditional right
of demand on the part of the holder thereof to receive payment of the unpaid
principal balance plus accrued interest on a short notice period not to exceed
seven days. Participating VRDOs provide the Funds with a specified undivided
interest (up to 100%) of the underlying obligation and the right to demand
payment of the unpaid principal balance plus accrued interest on the
Participating VRDOs from the financial institution on a specified number of
days' notice, not to exceed seven days. There is, however, the possibility that
because of default or insolvency, the demand feature of VRDOs or Participating
VRDOs may not be honored. Insured I and Insured II have been advised by their
counsel that the Funds should be entitled to treat the income received on
Participating VRDOs as interest from tax-exempt obligations.
 
     The average maturity of each Fund's portfolio securities varies based upon
FAM's assessment of economic and market conditions. The net asset value of the
shares of common stock of a close-end investment company, such as each Fund,
which invests primarily in fixed-income securities, changes as the general
levels of interest rates fluctuate. When interest rates decline, the value of a
fixed income portfolio can be expected to rise. Conversely, when interest rates
rise, the value of a fixed-income portfolio can be expected to decline. Prices
of longer-term securities generally fluctuate more in response to interest rate
changes than do short-term or medium-term securities. These changes in net asset
value are likely to be greater in the case of a fund having a leveraged capital
structure, such as the Funds.
 
     On a temporary basis, each Fund may invest in short-term tax-exempt
securities, short-term U.S. Government securities, repurchase agreements or
cash. Such securities or cash will not exceed 20% of each Fund's total assets
except during interim periods pending investment of the net proceeds from public
offerings of the Fund's securities and temporary defensive periods when, in the
opinion of FAM, prevailing market or economic conditions warrant.
 
     Each Fund is classified as non-diversified within the meaning of the
Investment Company Act, which means that the Fund is not limited by such Act in
the proportion of its total assets that it may invest in securities of a single
issuer. However, each Fund's investments are limited so as to qualify the Fund
for the special tax treatment afforded RICs under the Code. See "The
Reorganization -- Tax Consequences of the Reorganization". To qualify, among
other requirements, each Fund limits its investments so that, at the close of
each quarter of the taxable year, (i) not more than 25% of the market value of
the Fund's total assets are
 
                                       23
<PAGE>   28
 
invested in the securities (other than U.S. Government securities) of a single
issuer, and (ii) with respect to 50% of the market value of its total assets,
not more than 5% of the market value of its total assets are invested in the
securities (other than U.S. Government securities) of a single issuer. A fund
which elects to be classified as "diversified" under the Investment Company Act
must satisfy the foregoing 5% requirement with respect to 75% of its total
assets. To the extent that Insured I or Insured II assumes large positions in
the securities of a small number of issuers, the Fund's yield 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.
 
PORTFOLIO INSURANCE
 
     Under normal circumstances, at least 80% of each Fund's assets will be
invested in Municipal Bonds either (i) insured under an insurance policy
purchased by the Fund or (ii) insured under an insurance policy obtained by the
issuer thereof or any other party. The insurance policies in either instance
will be issued by insurance carriers that have total admitted assets (unaudited)
of at least $50,000,000 and insurance claims-paying ability ratings of AAA from
S&P and Aaa from Moody's. See Exhibit III to this Proxy Statement and Prospectus
for a brief description of S&P's and Moody's insurance claims-paying ability
ratings. Currently, a majority of the insured Municipal Bonds in each Fund's
portfolio are insured by the following insurance companies which satisfy the
foregoing requirements: AMBAC Indemnity Corporation, Capital Guaranty Insurance
Company, Financial Guaranty Insurance Company, Financial Security Assurance and
Municipal Bond Investors Assurance Corporation. Each Fund also may purchase
Municipal Bonds covered by insurance issued by any other insurance company which
satisfies the foregoing requirements. A majority of insured Municipal Bonds held
by each Fund will be insured under policies obtained by parties other than the
Fund.
 
     Each Fund may purchase, but has no obligation to purchase, separate mutual
fund insurance policies (the "Policies") from insurance companies meeting the
requirements set forth above which guarantee payment of principal and interest
on specified eligible Municipal Bonds purchased by the Fund. A Municipal Bond
will be eligible for coverage if it meets certain requirements of the insurance
company set forth in a Policy. In the event interest or principal on an insured
Municipal Bond is not paid when due, the insurer will be obligated under its
Policy to make such payment not later than 30 days after it has been notified
by, and provided with documentation from, the Fund that such nonpayment has
occurred.
 
     The Policies will be effective only as to insured Municipal Bonds
beneficially owned by a Fund. In the event of a sale of any Municipal Bonds held
by a Fund, the issuer of the relevant Policy will be liable only for those
payments of interest and principal which are then due and owing. The Policies
will not guarantee the market value of the insured Municipal Bonds or the value
of the shares of the Fund.
 
     The insurer will not have the right to withdraw coverage on securities
insured by its Policies and held by a Fund so long as such securities remain in
the Fund's portfolio. In addition, the insurer may not cancel its Policies for
any reason except failure to pay premiums when due. The Board of Directors of
each Fund reserves the right to terminate any of the Policies if it determines
that the benefits to the Fund of having its portfolio insured under such Policy
are not justified by the expense involved.
 
     The premiums for the Policies are paid by a Fund and the yield on the
Fund's portfolio is reduced thereby. FAM estimates that the cost of the annual
premiums for the Policies of each Fund currently range from approximately .10 of
1% to .25 of 1% of the principal amount of the Municipal Bonds covered by such
 
                                       24
<PAGE>   29
 
Policies. The estimate is based on the expected composition of each Fund's
portfolio of Municipal Bonds. Additional information regarding the Policies is
set forth in Exhibit III to this Proxy Statement and Prospectus. In instances in
which the Fund purchases Municipal Bonds insured under policies obtained by
parties other than the Fund, the Fund does not pay the premiums for such
policies; rather, the cost of such policies may be reflected in the purchase
price of the Municipal Bonds.
 
     It is the intention of FAM to retain any insured securities which are in
default or in significant risk of default and to place a value on the insurance
which ordinarily will be the difference between the market value of the
defaulted security and the market value of similar securities which are not in
default. In certain circumstances, however, FAM may determine that an
alternative value for the insurance, such as the difference between the market
value of the defaulted security and its par value, is more appropriate. FAM will
be unable to manage the portfolio of a Fund to the extent it holds defaulted
securities, which may limit its ability in certain circumstances to purchase
other Municipal Bonds. See "Net Asset Value" below for a more complete
description of each Fund's method of valuing defaulted securities and securities
which have a significant risk of default.
 
     There can be no assurance that insurance of the kind described above will
continue to be available to each Fund. In the event the Board of Directors of a
Fund determines that such insurance is unavailable or that the cost of such
insurance outweighs the benefits to the Fund, the Fund may discontinue its
policy of maintaining insurance for all or any of the Municipal Bonds held in
the Fund's portfolio. Although FAM periodically reviews the financial condition
of each insurer, there can be no assurance that the insurers will be able to
honor their obligations under all circumstances.
 
     The portfolio insurance reduces financial or credit risk (i.e., the
possibility that the owners of the insured Municipal Bonds will not receive
timely scheduled payments of principal or interest). However, the insured
Municipal Bonds are subject to market risk (i.e., fluctuations in market value
as a result of changes in prevailing interest rates.
 
DESCRIPTION OF MUNICIPAL BONDS
 
     Municipal Bonds include debt obligations issued to obtain funds for various
public purposes, including construction of a wide range of public facilities,
refunding of outstanding obligations and obtaining funds for general operating
expenses and loans to other public institutions and facilities. In addition,
certain types of industrial development bonds are issued by or on behalf of
public authorities to finance various privately operated facilities, including
pollution control facilities. For purposes of this Proxy Statement and
Prospectus, such obligations are Municipal Bonds if the interest paid thereon is
exempt from Federal income tax, even though such bonds may be "private activity
bonds" as discussed below.
 
     The two principal classifications of Municipal Bonds are "general
obligation" bonds and "revenue" or "special obligation" bonds. General
obligation bonds are secured by the issuer's pledge of faith, credit and taxing
power for the payment of principal and interest. Revenue or special obligation
bonds are payable only from the revenues derived from a particular facility or
class of facilities or, in some cases, from the proceeds from a special excise
tax or other specific revenue source such as from the user of the facility being
financed. Industrial development bonds are in most cases revenue bonds and
generally do not constitute the pledge of the credit or taxing power of the
issuer of such bonds. The payment of the principal and interest on such
industrial development bonds depends solely on the ability of the user of the
facility financed by the bonds to
 
                                       25
<PAGE>   30
 
meet its financial obligations and the pledge, if any, of real and personal
property so financed as security for such payment. Municipal Bonds also may
include "moral obligation" bonds which normally are issued by special purpose
public authorities. If an issuer of moral obligation bonds is unable to meet its
obligations, the repayment of such bonds becomes a moral commitment but not a
legal obligation of the state or municipality in question.
 
     Each Fund may purchase Municipal Bonds classified as "private activity
bonds" (in general, bonds that benefit non-governmental entities). Interest
received on certain tax-exempt securities 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 each Fund's assets that
may be invested in Municipal Bonds which may subject certain investors to an
alternative minimum tax. See "The Reorganization -- Summary -- Tax
Considerations" and "The Reorganization -- Agreement and Plan of
Reorganization -- Tax Consequences of the Reorganization".
 
     Federal tax legislation has limited the types and volume of bonds the
interest on which qualifies for a Federal income tax exemption. As a result,
this legislation and legislation which may be enacted in the future may affect
the availability of Municipal Bonds for investment by the Funds.
 
OTHER INVESTMENT POLICIES
 
     Both Insured I and Insured II have adopted certain other policies as set
forth below:
 
     Borrowings. Each Fund is authorized to borrow amounts of up to 5% of the
value of its total assets at the time of such borrowings; provided, however,
that each Fund is authorized to borrow money in excess of 5% of the value of its
total assets for the purpose of repurchasing its Common Stock or redeeming its
AMPS. Borrowings by each Fund create an opportunity for greater total return
but, at the same time, increase exposure to capital risk. In addition, borrowed
funds are subject to interest costs that may offset or exceed the return earned
on the borrowed funds. For so long as shares of a Fund's AMPS are rated by
Moody's or S&P, unless it receives written confirmation from Moody's or S&P, as
the case may be, that such action would not impair the ratings then assigned to
the shares of AMPS by Moody's or S&P, the issuing Fund will not borrow money
except for the purpose of clearing portfolio securities transactions (which
borrowings under any circumstances shall be limited to the lesser of $10 million
and an amount equal to 5% of the market value of the Fund's assets at the time
of such borrowings and further in the case of Insured II, which borrowings shall
be repaid within 60 days and not be extended or renewed).
 
     When-Issued Securities and Delayed Delivery Transactions. Insured I and
Insured II may purchase or sell Municipal Bonds on a delayed delivery basis or
on a when-issued basis at fixed purchase or sale terms. These transactions arise
when securities are purchased or sold by a Fund with payment and delivery taking
place in the future. The purchase will be recorded on the date that the Fund
enters into the commitment, and the value of the obligation thereafter will be
reflected in the calculation of the Fund's 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 the Fund will be established with its custodian consisting
of cash, cash equivalents or liquid Municipal Bonds having a market value at all
times at least equal to the amount of the commitment.
 
     Indexed and Inverse Floating Obligations. Insured I and Insured II 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 a Fund invests in these types of Municipal Bonds, the Fund's
 
                                       26
<PAGE>   31
 
return on such Municipal Bonds will be subject to risk with respect to the value
of the particular index. Also, a Fund may invest in so-called "inverse floating
rate bonds" 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, by a remarketing agent, or by reference to a short-term
tax-exempt interest rate index). Each Fund may purchase original issue inverse
floating rate bonds in both the primary and secondary markets and also may
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 generally will be
more volatile than the market values of fixed-rate tax-exempt securities. To
seek to limit the volatility of these securities, a Fund may purchase inverse
floating rate bonds with shorter-term maturities or which contain limitations on
the extent to which the interest rate may vary. FAM believes that indexed and
inverse floating obligations represent a flexible portfolio management
instrument for the Funds which allows FAM to vary the degree of investment
leverage relatively efficiently under different market conditions.
 
     Call Rights. Insured I and Insured II 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 the related Municipal
Bonds, subject to certain conditions. A Call Right that is not exercised prior
to the maturity of the related Municipal Bond will expire without value. The
economic effect of holding both the Call Right and the related Municipal Bond is
identical to holding a Municipal Bond as a non-callable security.
 
INFORMATION REGARDING 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 options and certain financial
futures contracts ("financial futures contracts") and options thereon. While
each Fund's use of hedging strategies is intended to reduce the volatility of
the net asset value of its Common Stock, the net asset value of its Common Stock
fluctuates. There can be no assurance that a Fund's hedging transactions will be
effective. In addition, because of the leveraged nature of each Fund's Common
Stock, hedging transactions will result in a larger impact on the net asset
value of the Common Stock than would be the case if the Common Stock were not
leveraged. For so long as a Fund's AMPS are rated by Moody's or S&P, as the case
may be, the Fund's use of options and financial futures contracts and options
thereon will be subject to certain limitations mandated by the rating agencies.
Furthermore, a Fund only will engage in hedging activities from time to time and
may not necessarily be engaging in hedging activities when movements in interest
rates occur.
 
     Certain Federal income tax requirements may limit a Fund's ability to
engage in hedging transactions. Gains from transactions in financial futures
contracts or options thereon distributed to stockholders are taxable as ordinary
income or, in certain circumstances, as long-term capital gains to stockholders.
 
     The following is a description of the transactions involving options and
financial futures contracts and options thereon in which each Fund may engage,
limitations on the use of such transactions and risks associated therewith. The
investment policies with respect to the hedging transactions of a Fund are not
 
                                       27
<PAGE>   32
 
fundamental policies and may be modified by the Board of Directors of the Fund
without the approval of the Fund's stockholders.
 
     Writing Covered Call Options. Each Fund is authorized to 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 the Fund at the stated exercise price until the option expires. Each
Fund writes only covered call options, which means that so long as the Fund is
obligated as the writer of a call option, it will own the underlying securities
subject to the option. The Fund may not write covered call options on underlying
securities in an amount exceeding 15% of the market value of its total assets.
Each Fund receives a premium from writing a call option, which increases the
Fund's return on the underlying security in the event the option expires
unexercised or is closed out at a profit. By writing a call, a 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 the Fund's
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. Each Fund is authorized to 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 terminated by entering
into the closing sale transaction. 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. A 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. Each Fund is authorized to
purchase and sell certain financial futures contracts and options thereon solely
for the purposes of hedging its investments in Municipal Bonds against declines
in value and hedging against increases in the cost of securities it intends to
purchase. A financial futures contract obligates the seller of a contract to
deliver and the purchaser of a contract to take delivery of the type of
financial instrument covered by the contract or, in the case of index-based
financial futures contracts, to make and accept a cash settlement, at a specific
future time for a specified price. A sale of financial futures contracts or
options thereon may provide a hedge against a decline in the value of portfolio
securities because such depreciation may be offset, in whole or in part, by an
increase in the value of the position in the financial futures contracts or
options. A purchase of financial futures contracts or options thereon may
provide a hedge against an increase in the cost of securities intended to be
purchased, because such appreciation may be offset, in whole or in part, by an
increase in the value of the position in the financial futures contracts or
options.
 
     The purchase or sale of a financial futures contract or option thereon
differs from the purchase or sale of a security in that no price or premium is
paid or received. Instead, an amount of cash or securities acceptable to 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 financial futures contract or option thereon fluctuates making the long
and short positions in the financial futures contract or option thereon more or
less valuable.
 
                                       28
<PAGE>   33
 
     Each Fund may purchase and sell financial futures contracts based on The
Bond Buyer Municipal Bond Index, a price-weighted measure of the market value of
40 large tax-exempt issues, and purchase and sell put and call options on such
financial futures contracts for the purpose of hedging Municipal Bonds which the
Fund holds or anticipates purchasing against adverse changes in interest rates.
 
     Each Fund also may purchase and sell financial futures contracts on U.S.
Government securities and purchase and sell put and call options on such
financial 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.
 
     Subject to policies adopted by its Board of Directors, each Fund also may
engage in transactions in other financial futures contracts or options thereon,
such as financial futures contracts or options on other municipal bond indices
which may become available, if FAM should determine that there normally is
sufficient correlation between the prices of such financial futures contracts or
options thereon and the Municipal Bonds in which the Fund invests to make such
hedging appropriate.
 
     Over-The-Counter Options. Each Fund is authorized to engage in transactions
involving financial futures contracts or options thereon on exchanges and in the
over-the-counter markets ("OTC options"). 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. OTC options transactions are two-party contracts
with price and terms negotiated by the buyer and seller.
 
     Restrictions on OTC Options. Each Fund is authorized to engage in
transactions 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 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 sale, or reduce the amount of proceeds that otherwise might be
realized.
 
     Risk Factors in Financial Futures Contracts and Options Thereon.
Utilization of financial futures contracts and options thereon involves the risk
of imperfect correlation in movements in the price of financial futures
contracts and options thereon and movements in the price of the security 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, a 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 or options thereon have different maturities, ratings, geographic
compositions or other characteristics than the security being hedged. In
addition, the correlation may be affected by additions to or deletions from the
index which serves as a basis for a financial futures contract or option
thereon. Finally, in the case of financial futures contracts on U.S. Government
securities and options on such financial futures contracts, the anticipated
correlation of price movements between the U.S. Government securities underlying
the financial futures contracts or options and Municipal Bonds may be adversely
affected by economic, political, legislative or other developments which have a
disparate impact on the respective markets for such securities.
 
     Under regulations of the Commodity Futures Trading Commission, the futures
trading activities described herein will not result in a Fund's being deemed a
"commodity pool," as defined under such
 
                                       29
<PAGE>   34
 
regulations, provided that the Fund adheres to certain restrictions. In
particular, the Fund may purchase and sell futures contracts and options thereon
(i) for bona fide hedging purposes, and (ii) for non-hedging purposes, if the
aggregate initial margin and premiums required to establish positions in such
contracts and options does not exceed 5% of the liquidation value of the Fund's
portfolio, after taking into account unrealized profits and unrealized losses on
any such contracts and options. Margin deposits may consist of cash or
securities acceptable to the broker and the relevant contract market.
 
     When a Fund purchases a financial futures contract, or writes a put option
or purchases a call option thereon, it will maintain an amount of cash, cash
equivalents (e.g., commercial paper and daily tender adjustable notes) or
short-term, high-grade, fixed-income securities in a segregated account with the
Fund's custodian, so that the amount so segregated plus the amount of initial
and variation margin held in the account of its broker equals the market value
of the financial futures contract, thereby ensuring that the use of such
financial futures contract is unleveraged.
 
     Although certain risks are involved in financial futures contracts and
options thereon, FAM believes that, because each Fund will engage in
transactions involving financial futures contracts and options thereon only for
hedging purposes, the options and futures portfolio strategies of a Fund will
not subject the Fund to certain risks frequently associated with speculation in
financial futures contracts and options thereon. A Fund may be restricted in
engaging in transactions involving financial futures contracts and options
thereon due to the 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.
 
     The volume of trading in the exchange markets with respect to Municipal
Bond options may be limited, and it is impossible to predict the amount of
trading interest that may exist in such options. In addition, there can be no
assurance that viable exchange markets will continue.
 
     Each Fund intends to enter into financial futures contracts and options
thereon, on an exchange or in the over-the-counter market, only if there appears
to be a liquid secondary market for such financial futures contracts or options.
There can be no assurance, however, that a liquid secondary market will exist at
any specific time. Thus, it may not be possible to close a financial futures
contract position or the related option. The inability to close financial
futures contract positions or the related options also could have an adverse
impact on a Fund's ability to hedge effectively its portfolio. There is also the
risk of loss by a Fund of margin deposits or collateral in the event of
bankruptcy of a broker with which the Fund has an open position in a financial
futures contract or the related option.
 
     The liquidity of a secondary market in a financial futures contract or
option thereon may be adversely affected by "daily price fluctuation limits"
established by commodity exchanges which limit the amount of fluctuation in a
financial futures contract or option price during a single trading day. Once the
daily limit has been reached in the financial futures contract or option, no
trades may be entered into at a price beyond the limit, thus preventing the
liquidation of open financial futures contract positions or the related options.
Prices in the past have reached or exceeded the daily limit on a number of
consecutive trading days.
 
     If it is not possible to close a financial futures contract position or the
related option entered into by a Fund, the Fund would continue to be required to
make daily cash payments of variation margin in the event of adverse price
movements. In such a situation, if the Fund has insufficient cash, it may have
to sell portfolio securities to meet daily variation margin requirements at a
time when it may be disadvantageous to do so.
 
                                       30
<PAGE>   35
 
     The successful use of these transactions also depends on the ability of FAM
to forecast correctly the direction and extent of interest rate movements within
a given time frame. To the extent interest rates remain stable during the period
in which a financial futures contract or option thereon 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, the Fund's total return for
such period may be less than if it had not engaged in the hedging transaction.
 
INVESTMENT RESTRICTIONS
 
     Insured I and Insured II have identical 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 the outstanding
shares of Common Stock and the outstanding shares of AMPS and any other
preferred stock, voting together as a single class, and a majority of the
outstanding shares of AMPS and any other preferred stock, voting separately as a
class. (For this purpose and under the Investment Company Act, "majority" means
for each such class the lesser of (i) 67% of the shares of each class of capital
stock represented at a meeting at which more than 50% of the outstanding shares
of each class of capital stock are represented or (ii) more than 50% of the
outstanding shares of each class of capital stock.) 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, however, 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 other than preferred stock or borrow
     amounts in excess of 5% of its total assets taken at market value;
     provided, however, that the Fund is authorized to borrow money in excess of
     5% of the value of its total assets for the purpose of repurchasing shares
     of Common Stock or redeeming shares of preferred stock.
 
          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 in accordance with its investment
     objective, policies and limitations.
 
          7. Purchase any securities on margin, except that (subject to
     investment restriction (4) above) 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).
 
                                       31
<PAGE>   36
 
          8. 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 hedging activities.
 
          9. 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;
     provided, however, that for purposes of this restriction, states,
     municipalities and their political subdivisions are not considered to be
     part of any industry.
 
     An additional investment restriction adopted by each Fund, which may be
changed by the Board of Directors, provides that the Fund may not 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 investment restriction (4) above or except as may
be necessary in connection with transactions in financial futures contracts and
options thereon.
 
     If a percentage restriction on investment policies or the investment or use
of assets set forth above is adhered to at the time a transaction is effected,
later changes in percentage resulting from changing values will not be
considered a violation.
 
RATING AGENCY GUIDELINES
 
     Each Fund intends that, so long as shares of its AMPS are outstanding, the
composition of its portfolio will reflect guidelines established by Moody's and
S&P in connection with the Fund's receipt of a rating for such shares on their
date of original issue of "aaa" from Moody's and AAA from S&P. Moody's and S&P,
nationally recognized statistical rating organizations, issue ratings for
various securities reflecting the perceived creditworthiness of such securities.
The guidelines for rating AMPS have been developed by Moody's and S&P in
connection with issuances of asset-backed and similar securities, including debt
obligations and variable rate preferred stocks, generally on a case-by-case
basis through discussions with the issuers of these securities. The guidelines
are designed to ensure that assets underlying outstanding debt or preferred
stock will be varied sufficiently and will be of sufficient quality and amount
to justify investment-grade ratings. The guidelines do not have the force of law
but have been adopted by each Fund in order to satisfy current requirements
necessary for Moody's and S&P to issue the above-described ratings for shares of
AMPS, which ratings generally are relied upon by institutional investors in
purchasing such securities. The guidelines provide a set of tests for portfolio
composition and asset coverage that supplement (and in some cases are more
restrictive than) the applicable requirements under the Investment Company Act.
 
     Each Fund may, but is not required to, adopt any modifications to these
guidelines that hereafter may be established by Moody's or S&P. Failure to adopt
any such modifications, however, may result in a change in the ratings described
above or a withdrawal of the ratings altogether. In addition, any rating agency
providing a rating for the shares of AMPS, at any time, may change or withdraw
any such rating. As set forth in the Articles Supplementary of each Fund, the
Board of Directors, without stockholder approval, may modify certain definitions
or restrictions which have been adopted by the Fund pursuant to the rating
agency guidelines, provided the Board of Directors has obtained written
confirmation from Moody's and S&P that any such change would not impair the
ratings then assigned by Moody's and S&P to the AMPS. See "The
Reorganization -- Risk Factors and Special Considerations -- Ratings
Considerations".

<PAGE>   37
 
     For so long as any shares of a Fund's AMPS are rated by Moody's or S&P, as
the case may be, a Fund's use of options and financial futures contracts and
options thereon will be subject to certain limitations mandated by the rating
agencies.
 
PORTFOLIO COMPOSITION
 
     Although the investment portfolios of both Funds must satisfy the same
standards of credit quality, 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 Municipal Bonds owned by Insured I as
of April 30, 1996, 86.4% are rated in the highest grade by Moody's or S&P, 90.3%
are rated in the highest two grades, 93.8% are rated in the highest three
grades, 99.1% are rated in the highest four grades, and 0.9% are unrated. The
comparable percentages for Insured II are 88.3% in the highest grade, 93.7% in
the highest two grades, 97.5% in the highest three grades, 99.5% in the highest
four grades and 0.5% unrated.
 
     There are small differences in concentration among the states of issuers of
the Municipal Bonds held in the portfolios of the Funds. For Insured I, as of
April 30, 1996, the highest concentration of Municipal Bonds was in the states
of California, Texas and Illinois, accounting for 16.5%, 9.4%, and 6.7% of the
Fund's portfolio, respectively, whereas for Insured II, the highest
concentration was in the states of Texas, California and Illinois, accounting
for 15.0%, 13.2% and 13.0% of the Fund's portfolio.
 
  Insured I
 
     As of April 30, 1996, approximately 95.1% of the market value of Insured
I's portfolio was invested in long-term municipal obligations and approximately
4.9% of the market value of Insured I's portfolio was invested in short-term
municipal obligations. The following table sets forth certain information with
respect to the composition of Insured I's long-term municipal obligation
investment portfolio as of April 30, 1996.

PORTFOLIO TRANSACTIONS
 
     The procedures for engaging in portfolio transactions are the same for both
Insured I and Insured II. Subject to policies established by the Board of
Directors of each Fund, FAM is primarily responsible for the execution of each
Fund's portfolio transactions. In executing such transactions, FAM 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 FAM generally seeks
reasonably competitive commission rates, Insured I and Insured II do not
necessarily pay the lowest commission or spread available.
 
     Neither Fund has any obligation to deal with any broker or dealer in the
execution of transactions in portfolio securities. Subject to obtaining the best
price and execution, securities firms which provide supplemental investment
research to FAM, including Merrill Lynch, Pierce, Fenner & Smith Incorporated
("Merrill Lynch"), may receive orders for transactions by a Fund. Information so
received will be in addition to, and not in lieu of, the services required to be
performed by FAM under its investment advisory agreements with the Funds, and
the expenses of FAM will not necessarily be reduced as a result of the receipt
of such supplemental information.
 
     The securities in which each Fund primarily invests are traded in the
over-the-counter markets, and each Fund normally deals directly with the dealers
who make markets in the securities involved, except in those circumstances where
better prices and execution are available elsewhere. Under the Investment
Company Act, except as permitted by exemptive order, persons affiliated with a
Fund are prohibited from dealing with the Fund as principals in the purchase and
sale of securities. Since transactions in the over-the-counter markets usually
involve transactions with dealers acting as principals for their own account, a
Fund will not deal with affiliated persons, including Merrill Lynch and its
affiliates, in connection with such transactions, except that pursuant to an
exemptive order obtained by FAM, a Fund may engage in principal transactions
 
                                       34
<PAGE>   39
 
with Merrill Lynch in high quality, short-term, tax-exempt securities. An
affiliated person of a Fund may serve as its broker in over-the-counter
transactions conducted on an agency basis.
 
     Insured I and Insured II also may make loans to tax-exempt borrowers in
individually negotiated transactions with the borrower. Because an active
trading market may not exist for such securities, the prices 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.
 
     The Board of Directors of each Fund has considered the possibility of
recapturing for the benefit of the Fund brokerage commissions, dealer spreads
and other expenses of possible portfolio transactions, such as underwriting
commissions, by conducting portfolio transactions through affiliated entities,
including Merrill Lynch. For example, brokerage commissions received by Merrill
Lynch could be offset against the investment advisory fees paid by the Fund to
FAM. After considering all factors deemed relevant, the Directors made a
determination not to seek such recapture. The Directors will reconsider this
matter from time to time.
 
     Periodic auctions are conducted for the Insured I AMPS and the Insured II
AMPS by the Auction Agent for the Funds. The auctions require the participation
of one or more broker-dealers, each of whom enters into an agreement with the
Auction Agent. After each auction, the Auction Agent pays a service charge, from
funds provided by the issuing Fund, to each broker-dealer at the annual rate of
1/4 of 1%, calculated on the basis of the purchase price of shares of the
relevant AMPS placed by such broker-dealer at such auction.
 
PORTFOLIO TURNOVER
 
     Generally, neither Insured I nor Insured II purchases securities for
short-term trading profits. However, either Fund may dispose of securities
without regard to the time that they have been held when such action, for
defensive or other reasons, appears advisable to FAM. Although each Fund
anticipates that its annual portfolio turnover rate should not exceed 100%, the
turnover rate may vary greatly from year to year or during periods within a
year. (The portfolio turnover rate is calculated by dividing the lesser of
purchases or sales of portfolio securities for the particular fiscal year by the
monthly average of the value of the portfolio securities owned by a Fund during
the particular fiscal year. For purposes of determining this rate, all
securities whose maturities at the time of acquisition are one year or less are
excluded.) The portfolio turnover rate for each of the years ended October 31,
1995 and 1994 was 59.71% and 45.71%, respectively, for Insured I and 64.18% and
47.85%, respectively, for Insured II.
 
NET ASSET VALUE
 
     The net asset value per share of Common Stock of each Fund is determined as
of 15 minutes after the close of business on the NYSE (generally, 4:00 P.M., New
York time) on each day during which the NYSE is open for trading. For purposes
of determining the net asset value of a share of Common Stock of each Fund, the
value of the securities held by the Fund plus any cash or other assets
(including interest accrued but not yet received) minus all liabilities
(including accrued expenses) and the aggregate liquidation value of the
outstanding shares of AMPS of the Fund is divided by the total number of shares
of Common Stock of the Fund outstanding at such time. Expenses, including the
fees payable to FAM, are accrued daily.
 
     The Municipal Bonds in which each Fund invests are traded primarily in the
over-the-counter markets. In determining net asset value, each Fund utilizes the
valuations of portfolio securities furnished by a pricing
 
                                       35
<PAGE>   40
 
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 of
the Fund. 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. Obligations 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.
 
CAPITAL STOCK
 
     Insured I and Insured II each has outstanding both Common Stock and AMPS.
Insured I Common Stock and Insured II Common Stock both are traded on the NYSE.
The shares of Insured I Common Stock commenced trading on the NYSE on March 27,
1992. As of April 30, 1996, the net asset value per share of the Insured I
Common Stock was $15.03 and the market price per share was $13.75. The shares of
Insured II Common Stock commenced trading on the NYSE on October 30, 1992. As of
April 30, 1996, the net asset value per share of the Insured II Common Stock was
$14.95 and the market price per share was $13.375.
 
     Each Fund is authorized to issue 200,000,000 shares of capital stock, all
of which shares initially were classified as Common Stock. The Board of
Directors of each Fund is authorized 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. In connection with each
Fund's offering of shares of AMPS, Insured I reclassified 12,800 shares of
unissued capital stock as AMPS, and Insured II reclassified 4,800 shares of
unissued capital stock as AMPS.
 
  Common Stock
 
     Holders of each Fund's Common Stock are entitled to share equally in
dividends declared by the Fund's Board of Directors payable to holders of the
Common Stock and in the net assets of the Fund available for distribution to
holders of the Common Stock after payment of the preferential amounts payable to
holders of any outstanding preferred stock. Holders of a Fund's Common Stock do
not have preemptive or conversion rights and shares of a Fund's Common Stock are
not redeemable. The outstanding shares of Common Stock of each Fund are fully
paid and nonassessable.
 
     So long as any shares of a Fund's AMPS or any other preferred stock are
outstanding, holders of the Fund's Common Stock will not be entitled to receive
any dividends of or other distributions from the Fund unless all accumulated
dividends on outstanding shares of the Fund's AMPS and any other preferred stock
have been paid, and unless asset coverage (as defined in the Investment Company
Act) with respect to such AMPS and any other preferred stock would be at least
200% after giving effect to such distributions.
 
                                       36
<PAGE>   41
 
  Preferred Stock
 
     Insured I AMPS are structured identically to Insured II AMPS. The AMPS of
each Fund are shares of preferred stock of the Fund that entitle their holders
to receive dividends when, as and if declared by the Board of Directors, out of
funds legally available therefor, at a rate per annum that may vary for the
successive dividend periods. Insured I AMPS and Insured II AMPS both have
liquidation preferences of $25,000 per share; neither Fund's AMPS are traded on
any stock exchange or over-the-counter. Each Fund's AMPS can be purchased at an
auction or through broker-dealers who maintain a secondary market in the AMPS.
 
     Auctions generally have been held and will be held every 28 days in the
case of the Insured I Series A AMPS, Series B AMPS, Series C AMPS and Series D
AMPS and every seven days in the case of the Insured I Series E AMPS unless
Insured I elects, subject to certain limitations, to have a special dividend
period. As of the auction held on May 15, 1996, the dividend rate on the Insured
I Series A AMPS was 3.67%; as of the auction held on May 15, 1996, the dividend
rate on the Insured I Series B AMPS was 3.69%; as of the auction held on May 15,
1996, the dividend rate on the Insured I Series C AMPS was 3.75%; as of the
auction held on May 8, 1996, the dividend rate on the Insured I Series D AMPS
was 3.54%; and as of the auction held on May 15, 1996, the dividend rate on the
Insured I Series E AMPS was 3.64%.
 
     Similarly, auctions generally have been held and will be held every 28 days
in the case of the Insured II Series A AMPS and every seven days in the case of
the Insured II Series B AMPS unless Insured II elects, subject to certain
limitations, to have a special dividend period. In connection with the auction
held on June 10, 1996, Insured II elected a special dividend period on the
Insured II Series A AMPS which ends February 3, 1997 and the dividend rate
during such special dividend period is 3.68%. The Insured I Series F AMPS to be
issued in the Reorganization for the Insured II Series A AMPS will have an
initial dividend period ending February 3, 1997 and an initial dividend rate of
3.68%. As of the auction held on May 24, 1996, the dividend rate on the Insured
II Series B AMPS was 3.625%.
 
     Under the Investment Company Act, each Fund is permitted to have
outstanding more than one series of preferred stock as long as no single series
has priority over another series as to the distribution of assets of the Fund or
the payment of dividends. Holders of a Fund's preferred stock do not have
preemptive rights to purchase any shares of AMPS or any other preferred stock
that might be issued. The net asset value per share of a Fund's AMPS equals its
liquidation preference plus accumulated dividends per share.
 
  Certain Provisions of the Charter
 
     Each Fund's Charter includes provisions that could have the effect of
limiting the ability of other entities or persons to acquire control of the 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. A Director may be removed from office with or
without cause by a vote of the holders of at least 66 2/3% of the votes entitled
to be voted on the matter. A Director elected by the holders of Common Stock,
AMPS and any other preferred stock may be removed only by action of such
holders, and a Director elected by the holders of AMPS and any other preferred
stock may be removed only by action of the holders of AMPS and any other
preferred stock. In addition, the Charter of each Fund requires the affirmative
vote of the holders of at least 66 2/3% of all of the Fund's shares of capital
stock, then entitled to be voted, voting as a single class, to approve, adopt or
authorize the following:
 
                                       37
<PAGE>   42
 
          (i) a merger or consolidation or statutory share exchange of the Fund
     with any other corporation or entity,
 
          (ii) a sale of all or substantially all of the Fund's assets (other
     than in the regular course of the Fund's investment activities), or
 
          (iii) a liquidation or dissolution of the Fund,
 
unless such action has been approved, adopted or authorized by the affirmative
vote of at least two-thirds of the entire Board of Directors, in which case the
affirmative vote of a majority of all of the votes entitled to be cast by
stockholders of the Fund, voting as a single class, is required. Such approval,
adoption or authorization of the foregoing also would require the favorable vote
of the holders of a majority of shares of preferred stock entitled to be voted
thereon, including the AMPS, voting as a separate class.
 
     In addition, conversion of a Fund to an open-end investment company would
require an amendment to the 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 affirmative vote
of the holders of at least 66 2/3% of the Fund's outstanding shares of capital
stock (including the AMPS and any other preferred 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 entire Board of Directors) and the affirmative vote of a majority of
votes entitled to be cast by holders of shares of preferred stock (including the
AMPS), voting separately as a class. Such a vote also would satisfy a separate
requirement in the Investment Company 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 Investment Company 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 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 no
longer would be listed on a stock exchange. Conversion to an open-end investment
company also would require redemption of all outstanding shares of preferred
stock (including the AMPS) and would require changes in certain of the Fund's
investment policies and restrictions, such as those relating to the issuance of
senior securities, the borrowing of money and the purchase of illiquid
securities.
 
     The Board of Directors of each Fund has determined that the 66 2/3% voting
requirements described above, which are greater than the minimum requirements
under Maryland law or the Investment Company Act, are in the best interests of
stockholders generally. Reference should be made to the Charter of each Fund on
file with the Commission for the full text of these provisions.
 
MANAGEMENT OF THE FUNDS
 
     Directors and Officers. The Boards of Directors of each of Insured I and
Insured II currently consist of six persons, five of whom are not "interested
persons", as defined in the Investment Company Act, of either Fund. The
Directors are responsible for the overall supervision of the operations of
Insured I and Insured II and perform the various duties imposed on the directors
of investment companies by the Investment Company Act and under applicable
Maryland law. Insured I and Insured II have the same officers. For further
information regarding the Directors and officers of each Fund, see "Election of
Directors".
 
                                       38

     Management and Advisory Arrangements. FAM serves as the investment adviser
for both Insured I and Insured II pursuant to separate investment advisory
agreements that, except for their termination dates, are identical. FAM is an
affiliate of MLAM, and both FAM and MLAM are owned and controlled by ML & Co.
FAM provides each Fund with the same investment advisory and management
services. FAM or MLAM acts as the investment adviser for more than 130
registered investment companies. FAM also offers portfolio management and
portfolio analysis services to individuals and institutions. As of May 31, 1996,
FAM and MLAM had a total of approximately $208.9 billion in investment company
and other portfolio assets under management (approximately $30.5 billion of
which were invested in municipal securities), including accounts of certain
affiliates of FAM. The principal business address of FAM is 800 Scudders Mill
Road, Plainsboro, New Jersey 08536.
 
     Each Fund's investment advisory agreement with FAM provides that, subject
to the direction of the Board of Directors of the Fund, FAM is responsible for
the actual management of the Fund's portfolio. The responsibility for making
decisions to buy, sell or hold a particular security for each Fund rests with
FAM, subject to review by the Board of Directors of the Fund.
 
     FAM provides the portfolio management for Insured I and Insured II. 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. FAM also
is responsible for the performance of certain administrative and management
services for each Fund.
 
     For the services provided by FAM under each Fund's investment advisory
agreement, the Fund pays a monthly fee at an annual rate of .50 of 1% of the
Fund's average weekly net assets (i.e., the average weekly value of the total
assets of the Fund, minus the sum of accrued liabilities of the Fund and
accumulated dividends on its shares of AMPS). For purposes of this calculation,
average weekly net assets are determined at the end of each month on the basis
of the average net assets of the 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.
 
     Each Fund's investment advisory agreement obligates FAM to provide
investment advisory services and to pay all compensation of and furnish office
space for officers and employees of the Fund connected with investment and
economic research, trading and investment management of the Fund, as well as the
compensation of all Directors of the Fund who are affiliated persons of FAM or
any of its affiliates. Each Fund pays all other expenses incurred in the
operation of the Fund, 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, fees and expenses with respect
to the issuance of AMPS, Commission fees, fees and expenses of unaffiliated
Directors, accounting and pricing costs, insurance, interest, brokerage costs,
litigation and other extraordinary or non-recurring expenses, mailing and other
expenses properly payable by the Fund. FAM provides accounting services to each
Fund, and each Fund reimburses FAM for its respective costs in connection with
such services.
 
     Unless earlier terminated as described below, the investment advisory
agreement between Insured I and FAM will continue from year to year if approved
annually (a) by the Board of Directors of Insured I or by a majority of the
outstanding shares of Insured I Common Stock and Insured I AMPS, voting together
as a single class, and (b) by a majority of the Directors of Insured I who are
not parties to such contract or "interested persons", as defined in the
Investment Company Act, of any such party. The contract is not
 
                                       39
<PAGE>   44
 
assignable and it 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
Insured I.
 
     Similarly, unless earlier terminated as described below, the investment
advisory agreement between Insured II and FAM will continue from year to year if
approved annually (a) by the Board of Directors of Insured II or by a majority
of the outstanding shares of Insured II Common Stock and Insured II AMPS, voting
together as a single class, and (b) by a majority of the Directors of Insured II
who are not parties to such contract or "interested persons" of any such party.
The contract is not assignable and it 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 Insured II.
 
VOTING RIGHTS
 
     Voting rights are identical for the holders of shares of Insured I Common
Stock and the holders of shares of Insured II Common Stock. Holders of each
Fund's Common Stock are entitled to one vote for each share held and will vote
with the holders of any outstanding shares of the Fund's AMPS or other preferred
stock on each matter submitted to a vote of holders of Common Stock, except as
set forth below.
 
     Stockholders of each Fund are entitled to one vote for each share held. The
shares of each Fund's Common Stock, AMPS and any other preferred stock do not
have cumulative voting rights, which means that the holders of more than 50% of
the shares of a Fund's Common Stock, AMPS and any other preferred stock voting
for the election of Directors can elect all of the Directors standing for
election by such holders, and, in such event, the holders of the remaining
shares of a Fund's Common Stock, AMPS and any other preferred stock will not be
able to elect any of such Directors.
 
     Voting rights of the holders of Insured I AMPS are identical to voting
rights of the holders of Insured II AMPS. Except as otherwise indicated below,
and except as otherwise required by applicable law, holders of shares of a
Fund's AMPS will be entitled to one vote per share on each matter submitted to a
vote of the Fund's stockholders and will vote together with the holders of
shares of the Fund's Common Stock as a single class.
 
     In connection with the election of a Fund's Directors, holders of shares of
a Fund's AMPS and any other preferred stock, voting separately as a class, shall
be entitled at all times to elect two of the Fund's Directors, and the remaining
Directors will be elected by holders of shares of the Fund's Common Stock and
shares of the Fund's AMPS and any other preferred stock, voting together as a
single class. In addition, if at any time dividends on outstanding shares of a
Fund's AMPS shall be unpaid in an amount equal to at least two full years'
dividends thereon or if at any time holders of any shares of a Fund's preferred
stock are entitled, together with the holders of shares of the Fund's AMPS, to
elect a majority of the Directors of the Fund under the Investment Company Act,
then the number of Directors constituting the Board of Directors automatically
shall be increased by the smallest number that, when added to the two Directors
elected exclusively by the holders of shares of AMPS and any other preferred
stock as described above, would constitute a majority of the Board of Directors
as so increased by such smallest number, and at a special meeting of
stockholders which will be called and held as soon as practicable, and at all
subsequent meetings at which Directors are to be elected, the holders of shares
of the Fund's AMPS and any other preferred stock, voting separately as a class,
will be entitled to elect the smallest number of additional Directors that,
together with the two Directors which such holders in any event will be entitled
to elect, constitutes a majority of the total number of Directors
 
                                       40
<PAGE>   45
 
of the Fund as so increased. The terms of office of the persons who are
Directors at the time of that election will continue. If the Fund thereafter
shall pay, or declare and set apart for payment in full, all dividends payable
on all outstanding shares of AMPS and any other preferred stock for all past
dividend periods, the additional voting rights of the holders of shares of AMPS
and any other preferred stock as described above shall cease, and the terms of
office of all of the additional Directors elected by the holders of shares of
AMPS and any other preferred stock (but not of the Directors with respect to
whose election the holders of shares of Common Stock were entitled to vote or
the two Directors the holders of shares of AMPS and any other preferred stock
have the right to elect in any event) will terminate automatically.
 
STOCKHOLDER INQUIRIES
 
     Stockholder inquiries with respect to Insured I and Insured II may be
addressed to either Fund by telephone at (609) 282-2800 or at the address set
forth on the cover page of this Proxy Statement and Prospectus.
 
DIVIDENDS AND DISTRIBUTIONS
 
     Insured I's current policy with respect to dividends and distributions
relating to shares of Insured I Common Stock is identical to Insured II's policy
with respect to shares of Insured II Common Stock. Each Fund intends to
distribute all of its net investment income. Dividends from such net investment
income are declared and paid monthly to holders of a Fund's Common Stock.
Monthly distributions to holders of a Fund's Common Stock normally consist of
substantially all of the net investment income remaining after the payment of
dividends on the Fund's AMPS. All net realized long-term or short-term capital
gains, if any, are distributed at least annually, pro rata to holders of shares
of a Fund's Common Stock and AMPS. While any shares of a Fund's AMPS are
outstanding, the Fund may not declare any cash dividend or other distribution on
the Fund's Common Stock, unless at the time of such declaration (1) all
accumulated dividends on the Fund's AMPS have been paid, and (2) the net asset
value of the Fund's portfolio (determined after deducting the amount of such
dividend or other distribution) is at least 200% of the liquidation value of the
Fund's outstanding shares of AMPS. This limitation on a Fund's ability to make
distributions on its Common Stock under certain circumstances could impair the
ability of the Fund to maintain its qualification for taxation as a RIC. See
"Agreement and Plan of Reorganization -- Tax Consequences of the
Reorganization".
 
     Similarly, Insured I's current policy with respect to dividends and
distributions relating to shares of Insured I AMPS is identical to Insured II's
current policy with respect to shares of Insured II AMPS. The holders of shares
of a Fund's AMPS are entitled to receive, when, as and if declared by the Board
of Directors of the Fund, out of funds legally available therefor, cumulative
cash dividends on their shares. Dividends on a Fund's shares of AMPS so declared
and payable shall be paid (i) in preference to and in priority over any
dividends so declared and payable on the Fund's Common Stock, and (ii) to the
extent permitted under the Code and to the extent available, out of net
tax-exempt income earned on the Fund's investments. Dividends for the Insured I
AMPS and the Insured II AMPS are paid through The Depository Trust Company
("DTC") (or a successor securities depository) on each dividend payment date.
DTC's normal procedures now provide for it to distribute dividends in same-day
funds to agent members, who in turn are expected to distribute such dividends to
the person for whom they are acting as agent in accordance with the instructions
of such person. Prior to each dividend payment date, the relevant Fund is
required to deposit with the Auction Agent sufficient funds for the payment of
such declared dividends. Neither Fund intends to establish any
 
                                       41
<PAGE>   46
 
reserves for the payment of dividends, and no interest will be payable in
respect of any dividend payment or payment on the shares of a Fund's AMPS which
may be in arrears.
 
     Dividends paid by each Fund, to the extent paid from tax-exempt income
earned on Municipal Bonds, are exempt from Federal income taxes, subject to the
possible application of the alternative minimum tax. However, each Fund is
required to allocate net capital gains and other income subject to regular
Federal income taxes, if any, proportionately between shares of its Common Stock
and shares of its AMPS in accordance with the current position of the IRS
described herein. Each Fund notifies the Auction Agent of the amount of any net
capital gains or other taxable income to be included in any dividend on shares
of AMPS prior to the auction establishing the applicable rate for such dividend.
The Auction Agent in turn notifies each broker-dealer whenever it receives any
such notice from a Fund, and each broker-dealer then notifies its customers who
are holders of the Fund's AMPS. Each Fund also may include such income in a
dividend on shares of its AMPS without giving advance notice thereof if it
increases the dividend by an additional amount to offset the tax effect thereof.
The amount of taxable income allocable to shares of a Fund's AMPS will depend
upon the amount of such income realized by the Fund and other factors, but
generally is not expected to be significant.
 
     For information concerning the manner in which dividends and distributions
to holders of each Fund's Common Stock may be reinvested automatically in shares
of the Fund's Common Stock, see "Automatic Dividend Reinvestment Plan" below.
Dividends and distributions may be taxable to stockholders under certain
circumstances as discussed below, whether they are reinvested in shares of a
Fund or received in cash.
 
     If Insured I or Insured II, as the case may be, retroactively allocates any
net capital gains or other income subject to regular Federal income taxes to
shares of its AMPS without having given advance notice thereof as described
above, which only may happen when such allocation is made as a result of the
redemption of all or a portion of the outstanding shares of its AMPS or the
liquidation of the Fund, the Fund will make certain payments to holders of
shares of its AMPS to which such allocation was made to offset substantially the
tax effect thereof. In no other instances will the Fund be required to make
payments to holders of shares of its AMPS to offset the tax effect of any
reallocation of net capital gains or other taxable income.
 
AUTOMATIC DIVIDEND REINVESTMENT PLAN
 
     Pursuant to each Fund's Automatic Dividend Reinvestment Plan (each, the
"Plan"), unless a holder of a Fund's Common Stock elects otherwise, all dividend
and capital gains distributions are reinvested automatically by Boston
EquiServe, as agent for stockholders in administering the Plan (the "Plan
Agent"), in additional shares of the Fund's Common Stock. Holders of a Fund's
Common Stock who elect not to participate in the Plan 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 Boston
EquiServe, as dividend paying agent. Such stockholders may elect not to
participate in the Plan and to receive all distributions of dividends and
capital gains in cash by sending written instructions to Boston EquiServe, as
dividend paying agent, at the address set forth below. Participation 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 capital gains
distribution.
 
                                       42
<PAGE>   47
 
     Whenever a Fund declares an ordinary income dividend or a capital gain
dividend (collectively referred to as "dividends") payable either in shares or
in cash, non-participants in the Plan receive cash, and participants in the Plan
receive the equivalent in shares of the Fund's Common Stock. The shares are
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 of the Fund's Common Stock from the Fund ("newly-issued
shares") or (ii) by purchase of outstanding shares of the Fund's 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 Fund's
Common Stock is equal to or less than the market price per share of the Fund's
Common Stock plus estimated brokerage commissions (such condition being referred
to herein as "market premium"), the Plan Agent invests the dividend amount in
newly-issued shares on behalf of the participant. The number of newly-issued
shares of the Fund's Common Stock to be credited to the participant's account is
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 invests 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 has 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. Each Fund intends to pay monthly
income dividends. Therefore, the period during which open-market purchases can
be made exists only from the payment date on the dividend through the date
before the next "ex-dividend" date, which typically is approximately ten days.
If, before the Plan Agent has completed its open-market purchases, the market
price of a share of a Fund's 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 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 ceases making open-market purchases and invests 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 are held by the Plan Agent in non-certificated form in the
name of the participant, and each stockholder's proxy includes 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.
 
                                       43
<PAGE>   48
 
     There are no brokerage charges with respect to shares issued directly by
Insured I or Insured II as a result of dividends or capital gains distributions
payable either in shares or in cash. However, each participant pays 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.
 
     The automatic reinvestment of dividends and distributions does not relieve
participants of any Federal, state or local income tax that may be payable (or
required to be withheld) on such dividends. See "The Reorganization -- Tax
Consequences of the Reorganization".
 
     Stockholders participating in the Plan may receive benefits not available
to stockholders not participating in the Plan. If the market price plus
commissions of a Fund's shares of Common Stock is above the net asset value,
participants in the Plan receive shares of the Fund's Common Stock at less than
they otherwise could purchase them and 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 receive distributions in shares with a net asset value greater than
the value of any cash distribution 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 neither
Fund normally redeems its shares, the price on resale may be more or less than
the net asset value.
 
     Each Fund reserves the right to amend or terminate its Plan. There is no
direct service charge to participants in the Plan; however, each Fund reserves
the right to amend its Plan to include a service charge payable by the
participants.
 
LIQUIDATION RIGHTS OF HOLDERS OF AMPS
 
     Upon any liquidation, dissolution or winding up of Insured I or Insured II,
as the case may be, whether voluntary or involuntary, the holders of shares of
the Fund's AMPS will be entitled to receive, out of the assets of the Fund
available for distribution to stockholders, before any distribution or payment
is made upon any shares of the Fund's Common Stock or any other capital stock of
the Fund ranking junior in right of payment upon liquidation to AMPS, $25,000
per share together with the amount of any dividends accumulated but unpaid
(whether or not earned or declared) thereon to the date of distribution, and
after such payment the holders of AMPS will be entitled to no other payments
except for any additional dividends. If such assets of the Fund shall be
insufficient to make the full liquidation payment on the AMPS and liquidation
payments on any other outstanding class or series of preferred stock of the Fund
ranking on a parity with the AMPS as to payment upon liquidation, then such
assets will be distributed among the holders of shares of AMPS and the holders
of shares of such other class or series ratably in proportion to the respective
preferential amounts to which they are entitled. After payment of the full
amount of liquidation distribution to which they are entitled, the holders of
shares of a Fund's AMPS will not be entitled to any further participation in any
distribution of assets by the Fund except for any additional dividends. A
consolidation, merger or share exchange of a Fund with or into any other entity
or entities or a sale, whether for cash, shares of stock, securities or
properties, of all or substantially all or any part of the assets of the Fund
shall not be deemed or construed to be a liquidation, dissolution or winding up
of the Fund.

TAX RULES APPLICABLE TO INSURED I, INSURED II AND THEIR STOCKHOLDERS
 
     The tax consequences associated with investment in shares of Insured I
Common Stock are identical to the tax consequences associated with investment in
shares of Insured II Common Stock. Similarly, the tax consequences associated
with investment in shares of Insured I AMPS are identical to the tax
consequences associated with investment in shares of Insured II AMPS. Insured I
and Insured II have elected and qualified for the special tax treatment afforded
RICs under the Code. As a result, in any taxable year in which they distribute
an amount equal to at least 90% of taxable net income and 90% of tax-exempt net
income (see below), the Funds (but not their stockholders) are not subject to
Federal income tax to the extent that they distribute their net investment
income and net realized capital gains. In prior taxable years and in the taxable
year of the Reorganization, each Fund has distributed substantially all of its
income. Insured I intends to continue to distribute substantially all of its
income in the taxable years following the Reorganization. If, at any time when
shares of a Fund's AMPS are outstanding the Fund does not meet the asset
coverage requirements of the Investment Company Act, the Fund is required to
suspend distributions to holders of shares of its Common Stock until the asset
coverage is restored. This can prevent the Fund from distributing at least 90%
of its net income and therefore can jeopardize the Fund's qualification for
taxation as a RIC. Upon any failure to meet the asset coverage requirements, the
Funds may, and under certain circumstances are required to, redeem shares of
AMPS in order to maintain or restore the requisite asset coverage and avoid the
adverse consequences of failing to qualify as a RIC.
 
     Each Fund is qualified 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 a Fund's total assets
consists of obligations exempt from Federal income tax ("tax-exempt
obligations") under Section 103(a) of the Code (relating generally to
obligations of a state or local governmental unit), the Fund is qualified to pay
exempt-interest dividends to its stockholders. Exempt-interest dividends are
dividends or any part thereof paid by a Fund which are attributable to interest
on tax-exempt obligations and designated by the Fund as exempt-interest
dividends in a written notice mailed to stockholders within 60 days after the
close of its taxable year. To the extent that the dividends distributed to a
Fund's stockholders are derived from interest income exempt from Federal income
tax under Code Section 103(a) and are properly designated as exempt-interest
dividends, they are excludable from a stockholder's gross income for Federal
income tax purposes. Exempt-interest dividends are included, however, in
determining the portion, if any, of a person's social security benefits and
railroad retirement benefits subject to Federal income taxes. Interest on
indebtedness incurred or continued to purchase or carry a Fund's shares is not
deductible for Federal income tax purposes to the extent attributable to
exempt-interest dividends. A tax adviser should be consulted with respect to
whether exempt-interest dividends retain the exclusion under Code Section 103(a)
if a stockholder would be treated as a "substantial user" or "related person"
under Code Section 147(a) with respect to property financed with the proceeds
from an issue of "industrial development bonds" or "private activity bonds," if
any, held by a Fund.
 
     Each Fund informs its stockholders annually as to the portion of the Fund's
distributions which constitutes exempt-interest dividends. Interest on
indebtedness incurred or continued to purchase or carry a Fund's shares is not
deductible for Federal income tax purposes.
 
     The IRS, in a revenue ruling, held that certain AMPS would be treated as
stock for Federal income tax purposes. The terms of the Insured I AMPS and the
Insured II AMPS are substantially similar, but not identical, to the AMPS
discussed in the revenue ruling, and in the opinion of Brown & Wood LLP, counsel
to
 
                                       45
<PAGE>   50
 
both Funds, the shares of each Fund's AMPS constitute stock and distributions
with respect to shares of such AMPS (other than distributions in redemption of
shares of AMPS subject to Section 302(b) of the Code) constitute dividends to
the extent of current and accumulated earnings and profits as calculated for
Federal income tax purposes. Nevertheless, the IRS could take a contrary
position, asserting, for example, that the shares of AMPS constitute debt. If
this position were upheld, the discussion of the treatment of distributions
below would not apply to holders of shares of AMPS. Instead, distributions by
each Fund to holders of shares of its AMPS would constitute interest, whether or
not they exceed the earnings and profits of the Fund, would be included in full
in the income of the recipient and taxed as ordinary income. Counsel believes
that such a position, if asserted by the IRS, would be unlikely to prevail.
 
     To the extent that a Fund's distributions are derived from interest on its
taxable investments or from an excess of net short-term capital gains over net
long-term capital losses ("ordinary income dividends"), such distributions are
considered taxable ordinary income for Federal income tax purposes.
Distributions, if any, from an excess of net long-term capital gains over net
short-term capital losses derived from the sale of securities or from certain
transactions in futures or options ("capital gain dividends") are taxable as
long-term capital gains for Federal income tax purposes, regardless of the
length of time the stockholder has owned Fund shares. Distributions by a Fund,
whether from exempt-interest income, ordinary income or capital gains, will not
be eligible for the dividends received deduction for corporations under the
Code.
 
     All or a portion of a Fund's gain from the sale or redemption of tax-exempt
obligations purchased at a market discount will be treated as ordinary income
rather than capital gain. This rule may increase the amount of ordinary income
dividends received by stockholders. Any loss upon the sale or exchange of Fund
shares held for six months or less is treated as long-term capital loss to the
extent of capital gain dividends received by the stockholder. In addition, such
loss is disallowed to the extent of any exempt-interest dividends received by
the stockholder. Distributions in excess of a Fund's earnings and profits first
will reduce the adjusted tax basis of a holder's shares and, after such adjusted
tax basis is reduced to zero, will constitute capital gains to such holder
(assuming the shares are held as a capital asset). If a 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 is treated for tax purposes as paid by the Fund and received by its
stockholders on December 31 of the year in which such dividend was declared.
 
     The IRS has taken the position in a revenue ruling that if a RIC has two
classes of shares it may designate distributions made to each class in any year
as consisting of no more than such class' proportionate share of particular
types of income, including exempt-interest dividends and capital gain dividends.
Thus, each Fund is required to allocate a portion of its net capital gains and
other taxable income to the shares of its AMPS. Each Fund may notify the Auction
Agent of the amount of any net capital gains and other taxable income to be
included in any dividend on shares of its AMPS prior to the auction establishing
the applicable rate for such dividend. Except for the portion of any dividend
that a Fund informs the Auction Agent will be treated as capital gains or other
taxable income, the dividends paid on the shares of AMPS constitute exempt-
interest dividends. Alternatively, each Fund may include such income in a
dividend on shares of its AMPS without giving advance notice thereof if it
increases the dividend by an additional amount to offset the tax effect thereof.
The amount of net capital gains and ordinary income allocable to shares of a
Fund's AMPS (the "taxable distribution") depends upon the amount of such gains
and income realized by the Fund and the total dividends paid by the Fund on
shares of its Common Stock and shares of its AMPS during a taxable year, but the
taxable distribution generally is not significant.
 
                                       46
<PAGE>   51
 
     In the opinion of Brown & Wood LLP counsel to both Funds, under current law
the manner in which each Fund allocates items of tax-exempt income, net capital
gains, and other taxable income, if any, between shares of its Common Stock and
shares of its AMPS will be respected for Federal income tax purposes. However,
the tax treatment of additional dividends may affect a Fund's calculation of
each class' allocable share of capital gains and other taxable income. In
addition, there is currently no direct guidance from the IRS or other sources
specifically addressing whether a Fund's method for allocating tax-exempt
income, net capital gains and other taxable income between shares of its Common
Stock and shares of its AMPS will be respected for Federal income tax purposes,
and it is possible that the IRS could disagree with counsel's opinion and
attempt to reallocate a Fund's net capital gains or other taxable income. In the
event of a reallocation, some of the dividends identified by a Fund as
exempt-interest dividends to holders of shares of its AMPS could be
recharacterized as additional capital gains or other taxable income. In the
event of such recharacterization, a Fund is not required to make payments to
such stockholders to offset the tax effect of such reallocation. In addition, a
reallocation could cause a Fund to be liable for income tax and excise tax on
any reallocated taxable income. Brown & Wood LLP has advised each Fund that, in
its opinion, if the IRS were to challenge in court the Fund's allocations of
income and gain, the IRS would be unlikely to prevail. The opinion of Brown &
Wood LLP, however, represents only its best legal judgment and is not binding on
the IRS or the courts.
 
     The Code requires a RIC to pay a nondeductible 4% excise tax to the extent
it does not distribute 98% of its ordinary income, determined on a calendar year
basis, and 98% of its capital gains, determined in general, on an October 31
year-end, plus certain undistributed amounts from previous years. The required
distributions, however, are based only on the taxable income of a regulated
investment company. The excise tax, therefore, generally does not apply to the
tax-exempt income of RICs, such as the Funds, that pay exempt-interest
dividends.
 
     The Code subjects interest received on certain otherwise tax-exempt
securities to an alternative minimum tax. The alternative minimum tax applies to
interest received on "private activity bonds" issued after August 7, 1986.
"Private activity bonds" are bonds which, although tax-exempt, are used for
purposes other than those generally performed by governmental units and which
benefit non-governmental entities (e.g., bonds used for industrial development
or housing purposes). Income received on such bonds is classified as an item of
"tax preference" which could subject investors in such bonds, including
stockholders of the Funds, to an increased alternative minimum tax. Each Fund
purchases such "private activity bonds" and reports to stockholders within 60
days after its fiscal year-end the portion of its dividends declared during the
year which constitutes an item of tax preference for alternative minimum tax
purposes. The Code further provides that corporations are subject to an
alternative minimum tax based, in part, on certain differences between taxable
income as adjusted for other tax preferences and the corporation's "adjusted
current earnings" which more closely reflect a corporation's economic income.
Because an exempt-interest dividend paid by a Fund is included in adjusted
current earnings, a corporate stockholder may be required to pay an alternative
minimum tax on exempt-interest dividends paid by such Fund.
 
     Under certain provisions of the Code, some stockholders may be subject to a
31% withholding tax on certain ordinary income dividends and on capital gain
dividends and redemption payments ("backup withholding"). Generally,
stockholders subject to backup withholding will be those for whom no taxpayer
identification number is on file with a Fund or who, to the Fund's knowledge,
have furnished an incorrect number. When establishing an account, an investor
must certify under penalty of perjury that such number is correct and that such
stockholder is not otherwise subject to backup withholding.

     Ordinary income dividends paid to stockholders who are nonresident aliens
or foreign entities are subject to a 30% United States withholding tax under
existing provisions of the Code applicable to foreign individuals and entities
unless a reduced rate of withholding or a withholding exemption is provided
under applicable treaty law.
 
     A loss realized on a sale or exchange of shares of a Fund is disallowed if
other Fund shares are acquired (whether under the Automatic Dividend
Reinvestment Plan or otherwise) within a 61-day period beginning 30 days before
and ending 30 days after the date that the shares are disposed of. In such a
case, the basis of the shares acquired will be adjusted to reflect the
disallowed loss.
 
     The Code provides that every stockholder required to file a tax return must
include for information purposes on such return the amount of exempt-interest
dividends received from all sources (including the Funds) during the taxable
year.
 
AGREEMENT AND PLAN OF REORGANIZATION
 
GENERAL
 
     Under the Agreement and Plan of Reorganization (attached hereto as Exhibit
I), Insured I will acquire all of the assets, and will assume all of the
liabilities, of Insured II, in exchange solely for an equal aggregate value of
Insured I Common Stock, Insured I Series F AMPS and Insured I Series G AMPS to
be issued by Insured I. Upon receipt by Insured II of such shares, Insured II
will distribute the shares of Insured I Common Stock to the holders of Insured
II Common Stock, the shares of Insured I Series F AMPS to the holders of Insured
II Series A AMPS and the shares of Insured I Series G AMPS to the holders of
Insured II Series B AMPS in exchange for their shares in Insured II. Separate
Articles Supplementary to the Articles of Incorporation of Insured I
establishing the powers, rights and preferences of the Insured I Series F AMPS
and the Insured I Series G AMPS will have been filed with the State Department
of Assessments and Taxation of Maryland (the "Maryland Department") prior to the
closing of the Reorganization. As soon as practicable after the date that the
Reorganization takes place (the "Exchange Date"), Insured II will file Articles
of Dissolution with the Maryland Department to effect the formal dissolution.
 
     Insured II will distribute the shares of Insured I Common Stock, Insured I
Series F AMPS and Insured I Series G AMPS received by it pro rata to its holders
of record of Insured II Common Stock, Insured II Series A AMPS and Insured II
Series B AMPS, respectively, in exchange for such stockholders' shares in
Insured II. Such distribution would be accomplished by opening new accounts on
the books of Insured I in the names of the common and preferred stockholders of
Insured II and transferring to those stockholder accounts the Insured I Common
Stock, Insured I Series F AMPS and Insured I Series G AMPS previously credited
on those books to the account of Insured II. Each newly-opened account on the
books of Insured I for the previous holders of Insured II Common Stock would
represent the respective pro rata number of shares of Insured I Common Stock
(rounded down, in the case of fractional shares, to the next largest number of
whole shares) due such holder of Insured II Common Stock. No fractional shares
of Insured I Common Stock will be issued. In lieu thereof, Insured I's transfer
agent, Boston EquiServe, will aggregate all fractional shares of Insured I
Common Stock 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 a
pro rata share of the proceeds from such sale upon surrender of the Insured II
Common Stock certificates. Similarly, each newly-opened account on the books of
Insured I for the previous holders of Insured II Series A AMPS would represent
the respective pro
 
                                       48
<PAGE>   53
 
rata number of shares of Insured I Series F AMPS due such holder of Insured II
Series A AMPS, and each newly-opened account on the books of Insured I for the
previous holders of Insured II Series B AMPS would represent the respective pro
rata number of shares of Insured I Series G AMPS due such holder of Insured II
Series B AMPS. See "Surrender and Exchange of Insured II Stock Certificates"
below for a description of the procedures to be followed by Insured II
stockholders to obtain their Insured I Common Stock (and cash in lieu of
fractional shares, if any), Insured I Series F AMPS or Insured I Series G AMPS,
as the case may be.
 
     Accordingly, as a result of the Reorganization, every holder of Insured II
Common Stock would own shares of Insured I Common Stock 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 Insured II Common Stock immediately prior to the
Exchange Date. Since the Insured I Common Stock would be issued at net asset
value in exchange for the net assets of Insured II having a value equal to the
aggregate net asset value of those shares of Insured I Common Stock, the net
asset value per share of Insured I Common Stock should remain virtually
unchanged by the Reorganization. Similarly, since the Insured I Series F AMPS
would be issued at a liquidation preference and value per share equal to the
liquidation preference and value per share of the Insured II Series A AMPS, and
the Insured I Series G AMPS would be issued at a liquidation preference and
value per share equal to the liquidation preference and value per share of the
Insured II Series B AMPS, the respective liquidation preference and value per
share of the Insured I Series F AMPS and the Insured I Series G AMPS will remain
unchanged by the Reorganization. Thus, the Reorganization will result in no
dilution of net asset value of the Insured I Common Stock, other than to reflect
the costs of the Reorganization, and will result in no dilution of liquidation
preference and value of the Insured I Series F AMPS or Insured I Series G AMPS.
However, as a result of the Reorganization, a stockholder of either Fund likely
will hold a reduced percentage of ownership in the larger combined entity than
he or she did in either of the constituent Funds.
 
PROCEDURE
 
     At meetings of the Boards of Directors of Insured I and Insured II held on
June 18, 1996 and May 3, 1996, respectively, the Boards of Directors of Insured
I and Insured II, respectively, including all of the Directors who are not
"interested persons", as defined in the Investment Company Act, of Insured I and
Insured II unanimously approved the Agreement and Plan of Reorganization and the
submission of such Agreement and Plan of Reorganization to the Fund's respective
stockholders for approval.
 
     Also on June 18, 1996, the Board of Directors of Insured I approved the
filing of separate Articles Supplementary to Insured I's Articles of
Incorporation establishing the powers, rights and preferences of the Insured I
Series F AMPS and the Insured I Series G AMPS in order that they may be given to
holders of Insured II Series A AMPS and Insured II Series B AMPS as part of the
Reorganization.
 
     As a result of such Board approvals, Insured I and Insured II jointly filed
a proxy statement with the Commission soliciting a vote of the stockholders of
Insured I and Insured II to approve the Reorganization. The costs of such
solicitation are to be paid by Insured I after the Reorganization so as to be
borne equally and exclusively on a per share basis by the holders of Insured I
Common Stock and Insured II Common Stock. It is anticipated that annual meetings
of stockholders of Insured I and Insured II will be held on September 9, 1996.
If the stockholders of both Insured I and Insured II approve the Reorganization,
the Reorganization will take place as soon as practicable after such approval,
provided that the Funds have obtained prior to that time
 
                                       49
<PAGE>   54
 
a favorable private letter ruling from the IRS concerning the tax consequences
of the Reorganization as set forth in the Agreement and Plan of Reorganization.
 
     THE BOARDS OF DIRECTORS OF INSURED I AND INSURED II RECOMMEND THAT THE
STOCKHOLDERS OF THE RESPECTIVE FUNDS APPROVE THE AGREEMENT AND PLAN OF
REORGANIZATION.
 
TERMS OF THE AGREEMENT AND PLAN OF REORGANIZATION
 
     The following is a summary of the significant terms of the Agreement and
Plan of Reorganization. This summary is qualified in its entirety by reference
to the Agreement and Plan of Reorganization, attached hereto as Exhibit I.
 
     Valuation of Assets and Liabilities. The respective assets of Insured I and
Insured II will be valued on the business day prior to the Exchange Date (the
"Valuation Date"). The valuation procedures are the same for both Funds: net
asset value per share of the Insured I Common Stock and the Insured II Common
Stock will be determined as of 15 minutes after the close of business on the
NYSE (generally, 4:00 P.M., New York time) on the Valuation Date. For the
purpose of determining the net asset value of a share of the Insured I Common
Stock or the Insured II Common Stock, the value of the securities held by the
issuing Fund plus any cash or other assets (including interest accrued but not
yet received) minus all liabilities (including accrued expenses) and the
aggregate liquidation value of the outstanding shares of AMPS of the issuing
Fund is divided by the total number of shares of Common Stock of the issuing
Fund outstanding at such time. Daily expenses, including the fees payable to
FAM, will accrue on the Valuation Date.
 
     The Municipal Bonds in which each Fund invests are traded primarily in the
over-the-counter markets. In determining net asset value on the Valuation Date,
each Fund will utilize the valuations of portfolio securities furnished by a
pricing service approved by the Boards of Directors of the Funds. 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 will be valued at fair market value on a
consistent basis as determined by the pricing service using a matrix system to
determine valuations. The Boards of Directors of Insured I and Insured II have
determined in good faith that the use of a pricing service is a fair method of
determining the valuation of portfolio securities. Positions in financial
futures contracts will be valued on the Valuation Date at closing prices for
such contracts established by the exchange on which they are traded, or if
market quotations are not readily available, will be valued at fair value on a
consistent basis using methods determined in good faith by the Board of
Directors.
 
     Distribution of Insured I Common Stock, Insured I Series F AMPS and Insured
I Series G AMPS. On the Exchange Date, Insured I will issue to Insured II a
number of shares of Insured I Common Stock the aggregate net asset value of
which will equal the aggregate net asset value of shares of Insured II Common
Stock on the Valuation Date. Each holder of Insured II Common Stock will receive
the number of shares of Insured I Common Stock corresponding to his or her
proportionate interest in the aggregate net asset value of the Insured II Common
Stock.
 
     On the Exchange Date, Insured I also will issue to Insured II a number of
shares of Insured I Series F AMPS the aggregate liquidation preference of which
will equal the aggregate liquidation preference of Insured II Series A AMPS on
the Valuation Date, as well as a number of shares of Insured I Series G AMPS the
aggregate liquidation preference of which will equal the aggregate liquidation
preference of Insured II Series B AMPS on the Valuation Date. Each holder of
Insured II Series A AMPS or Insured II Series B AMPS, as
 
                                       50
<PAGE>   55
 
the case may be, will receive the number of shares of Insured I Series F AMPS or
Insured I Series G AMPS corresponding to his or her proportionate interest in
the aggregate liquidation preference and value of the Insured II Series A AMPS
or the Insured II Series B AMPS. No sales charge or fee of any kind will be
charged to Insured II stockholders in connection with their receipt of Insured I
Common Stock, Insured I Series F AMPS and Insured I Series G AMPS in the
Reorganization. It is anticipated that the Insured I Series F AMPS will follow a
similar auction schedule and procedures as those presently followed by the
Insured II Series A AMPS, and that the Insured I Series G AMPS will follow a
similar auction schedule and procedures as those presently followed by the
Insured II Series B AMPS. As a result of the Reorganization, the last dividend
period for the Insured II Series A AMPS and Insured II Series B AMPS prior to
the Exchange Date may be shorter than the dividend period for such AMPS
determined as set forth in the applicable Articles Supplementary.
 
     Expenses. Insured I 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 materials
distributed to each Fund's Board of Directors, expenses incurred in connection
with the preparation of the Agreement and Plan of Reorganization, a registration
statement on Form N-14 and a private letter ruling request to the IRS,
Commission and state securities commission filing fees and legal and audit fees
in connection with the Reorganization, costs of printing and distributing this
Proxy Statement and Prospectus, legal fees incurred preparing each Fund's board
materials, attending each Fund's board meetings and preparing the minutes,
accounting fees associated with each Fund's financial statements, stock exchange
fees, rating agency fees, portfolio transfer taxes (if any), and any similar
expenses incurred in connection with the Reorganization. In this regard,
expenses of the Reorganization will be deducted from the assets of the combined
fund so as to be borne equally and exclusively on a per share basis by the
holders of Insured I Common Stock and Insured II Common Stock. Neither Insured I
nor Insured II shall pay any expenses of its respective stockholders arising out
of or in connection with the Reorganization.
 
     Required Approvals. Under Insured I's Articles of Incorporation (as amended
to date and including Articles Supplementary establishing the powers, rights and
preferences of the Insured I AMPS), relevant Maryland law and the rules of the
NYSE, stockholder approval of the Agreement and Plan of Reorganization requires
the affirmative vote of stockholders representing more than 50% of the
outstanding shares of Insured I Common Stock and Insured I AMPS, voting together
as a single class, and of the Insured I AMPS, voting separately as a class.
Similarly, under Insured II's Articles of Incorporation (as amended to date and
including Articles Supplementary establishing the powers, rights and preferences
of the Insured II AMPS), relevant Maryland law and the rules of the NYSE,
stockholder approval of the Agreement and Plan of Reorganization requires the
affirmative vote of stockholders representing more than 50% of the outstanding
shares of Insured II Common Stock and Insured II AMPS, voting together as a
single class, and of the Insured II AMPS, voting separately as a class.
 
     Deregistration and Dissolution. Following the transfer of the assets and
liabilities of Insured II to Insured I and the distribution of shares of Insured
I Common Stock, Insured I Series F AMPS and Insured I Series G AMPS to Insured I
stockholders, Insured II will terminate its registration under the Investment
Company Act and its incorporation under Maryland law and will withdraw its
authority to do business in any state where it is required to do so.
 
     Amendments and Conditions. The Agreement and Plan of Reorganization may be
amended at any time prior to the Exchange Date with respect to any of the terms
therein. The obligations of Insured I and Insured
 
                                       51
<PAGE>   56
 
II pursuant to the Agreement and Plan of Reorganization are subject to various
conditions, including a registration statement on Form N-14 being declared
effective by the Commission, approval of the Reorganization by the stockholders
of Insured I and Insured II, a favorable IRS ruling being received as to tax
matters, an opinion of counsel as to securities matters being received and the
continuing accuracy of various representations and warranties of Insured I and
Insured II being confirmed by the respective parties.
 
     Postponement, Termination. Under the Agreement and Plan of Reorganization,
the Board of Directors of either Fund may cause the Reorganization to be
postponed or abandoned should either Board determine that it is in the best
interests of the stockholders of its respective Fund to do so. The Agreement and
Plan of Reorganization may be terminated, and the Reorganization abandoned at
any time (whether before or after adoption thereof by the stockholders of either
Fund), prior to the Exchange Date, or the Exchange Date may be postponed: (i) by
mutual consent of the Boards of Directors of Insured I and Insured II; (ii) by
the Board of Directors of Insured I if any condition to Insured I's obligations
set forth in Section 8 of the Agreement and Plan of Reorganization has not been
fulfilled or waived by such Board; or (iii) by the Board of Directors of Insured
II if any condition to Insured II's obligations set forth in Section 9 of the
Agreement and Plan of Reorganization has not been fulfilled or waived by such
Board.
 
POTENTIAL BENEFITS TO INSURED I COMMON STOCKHOLDERS AND INSURED II COMMON
STOCKHOLDERS AS A RESULT OF THE REORGANIZATION
 
     In approving the Reorganization, the Board of Directors of each Fund
identified certain benefits that are likely to result from the Reorganization,
including lower expenses per share of Common Stock, greater efficiency and
flexibility in portfolio management and a more liquid trading market for the
shares of Common Stock of the combined fund. With respect to Insured II,
following the Reorganization Insured II stockholders will remain invested in a
closed-end fund that has investment objectives and policies similar to that of
Insured II. The Boards also considered the possible risks and costs of combining
the Funds, and 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 (i) presents no significant risks that
would outweigh the benefits discussed above and (ii) involves minimal costs
(including relatively minor legal, accounting and administrative costs).
 
     The surviving fund that would result from the Reorganization would have a
larger asset base than either Fund has currently. Based on data presented by
FAM, the Board of each Fund believes that administrative expenses for a larger
combined fund would be less than the aggregate expenses for the individual
Funds, resulting in a lower expense ratio for common stockholders of the
combined fund and higher earnings per common share. In particular, certain fixed
costs, such as costs of printing stockholder reports and proxy statements, legal
expenses, audit fees, mailing costs and other expenses will be spread across a
larger asset base, thereby lowering the expense ratio for the combined fund. To
illustrate the potential economies of scale, as of April 30, 1996, the total
annualized operating expense ratio for Insured I was 0.64%, based on average net
assets of approximately $1.0 billion including AMPS, and 0.93%, based on average
net assets of approximately $706.5 million excluding AMPS, and the total
annualized operating expense ratio for Insured II was 0.67%, based on average
net assets of approximately $374.9 million including AMPS, and
 
                                       52
<PAGE>   57
 
0.98%, based on average net assets of approximately $254.9 million excluding
AMPS. If the Reorganization had taken place on April 30, 1996, the overall
operating expense ratio for the combined fund on a pro forma basis would have
been 0.62%, based on average net assets of approximately $1.4 billion including
AMPS, and 0.90%, based on average net assets of approximately $961.5 million
excluding AMPS.
 
     Management projections estimate that Insured I will have net assets in
excess of $1.3 million upon completion of the Reorganization. A larger asset
base should provide benefits in portfolio management. After the Reorganization,
Insured I 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 the Municipal Bonds
(e.g., added indenture provisions covering call protection, sinking funds and
audits for the benefit of large holders) prior to purchase.
 
     Based on the foregoing, the Boards concluded that the Reorganization
presents no significant risks or costs (including legal, accounting and
administrative costs) that would outweigh the benefits discussed above.
 
     In approving the Reorganization, the Board of Directors of each Fund
determined that, with respect to net asset value and liquidation preference, the
interests of existing stockholders of the Fund would not be diluted as a result
of the Reorganization. Although the Reorganization is expected to result in a
reduction in net asset value per share of the combined fund after the
Reorganization of approximately $.01 as a result of the estimated costs of the
Reorganization, management of each Fund advised its Board that it expects that
such costs would be recovered within [18] months after the Exchange Date.
 
     It is not anticipated that the Reorganization directly would benefit the
holders of shares of Insured I AMPS or Insured II AMPS; however, the
Reorganization will not adversely affect the holders of shares of AMPS of either
Fund and the expenses of the Reorganization will not be borne by the holders of
shares of AMPS of either Fund.
 
SURRENDER AND EXCHANGE OF INSURED II STOCK CERTIFICATES
 
     After the Exchange Date, each holder of an outstanding certificate or
certificates formerly representing shares of Insured II Common Stock, Insured II
Series A AMPS or Insured II Series B AMPS, as the case may be, will be entitled
to receive, upon surrender of his or her certificate or certificates, a
certificate or certificates representing the number of shares of Insured I
Common Stock, Insured I Series F AMPS or Insured I Series G AMPS distributable
with respect to such holder's shares of Insured II Common Stock, Insured II
Series A AMPS or Insured II Series B AMPS, together with cash in lieu of any
fractional shares. Promptly after the Exchange Date, the transfer agent for the
Insured I Common Stock, the Insured I Series F AMPS or the Insured I Series G
AMPS, as the case may be, will mail to each holder of certificates formerly
representing shares of Insured II Common Stock, Insured II Series A AMPS or
Insured II Series B AMPS, as the case may be, a letter of transmittal for use in
surrendering his or her certificates for certificates representing shares of
Insured I Common Stock, Insured I Series F AMPS or Insured I Series G AMPS, as
the case may be, and cash in lieu of any fractional shares.
 
     PLEASE DO NOT SEND IN ANY STOCK CERTIFICATES AT THIS TIME. UPON
CONSUMMATION OF THE REORGANIZATION, INSURED II COMMON AND PREFERRED STOCKHOLDERS
WILL BE FURNISHED WITH INSTRUCTIONS FOR EXCHANGING THEIR INSURED II STOCK
CERTIFICATES FOR INSURED I STOCK CERTIFICATES AND, IF APPLICABLE, CASH IN LIEU
OF FRACTIONAL SHARES.
 
                                       53
<PAGE>   58
 
     From and after the Exchange Date, certificates formerly representing shares
of Insured II Common Stock, Insured II Series A AMPS or Insured II Series B
AMPS, as the case may be, will be deemed for all purposes to evidence ownership
of the number of full shares of Insured I Common Stock, Insured I Series F AMPS
or Insured I Series G AMPS distributable with respect to such shares of Insured
II in the Reorganization, provided, that until such Insured II stock
certificates have been so surrendered, no dividends payable to the holders of
record of Insured I Common Stock, Insured I Series F AMPS or Insured I Series G
AMPS, as the case may be, as of any date subsequent to the Exchange Date will be
paid to the holders of such outstanding Insured II stock certificates. Dividends
payable to holders of record of shares of Insured I Common Stock, Insured I
Series F AMPS or Insured I Series G AMPS, as the case may be, as of any date
after the Exchange Date and prior to the exchange of certificates by any Insured
II stockholder will be paid to such stockholder, without interest, at the time
such stockholder surrenders his or her Insured II stock certificates for
exchange.
 
     From and after the Exchange Date, there will be no transfers on the stock
transfer books of Insured II. If, after the Exchange Date, certificates
representing shares of Insured II Common Stock, Insured II Series A AMPS or
Insured II Series B AMPS are presented to Insured I, they will be cancelled and
exchanged for certificates representing Insured I Common Stock, Insured I Series
F AMPS or Insured I Series G AMPS, as the case may be, and cash in lieu of
fractional shares, if any, distributable with respect to such Insured II Common
Stock, Insured II Series A AMPS or Insured II Series B AMPS in the
Reorganization.
 
TAX CONSEQUENCES OF THE REORGANIZATION
 
     General. The Reorganization has been structured with the intention that it
qualify for Federal income tax purposes as a tax-free reorganization under
Section 368(a)(1)(C) of the Code. Insured I and Insured II each has elected and
qualified for the special tax treatment afforded RICs under the Code, and
Insured I intends to continue to so qualify after the Reorganization. Insured I
and Insured II have jointly requested a private letter ruling from the IRS that
for Federal income tax purposes: (i) the Reorganization, as described, will
constitute a reorganization within the meaning of Section 368(a)(1)(C) of the
Code, and Insured I and Insured II will each be deemed a "party" to a
Reorganization within the meaning of Section 368(b) of the Code; (ii) in
accordance with Section 361(a) of the Code, no gain or loss will be recognized
to Insured II as a result of the Reorganization or on the distribution of
Insured I Common Stock, Insured I Series F AMPS and Insured I Series G AMPS to
Insured II stockholders under Section 361(c)(1) of the Code; (iii) under Section
1032 of the Code, no gain or loss will be recognized to Insured I as a result of
the Reorganization; (iv) in accordance with Section 354(a)(1) of the Code, no
gain or loss will be recognized to the stockholders of Insured II on the receipt
of Insured I Common Stock, Insured I Series F AMPS and Insured I Series G AMPS
in exchange for their corresponding Insured II Common Stock, Insured II Series A
AMPS and Insured II Series B AMPS (except to the extent that Insured II Common
Stockholders receive cash representing an interest in fractional shares of
Insured I in the Reorganization); (v) in accordance with Section 362(b) of the
Code, the tax basis of the Insured II assets in the hands of Insured I will be
the same as the tax basis of such assets in the hands of Insured II immediately
prior to the consummation of the Reorganization; (vi) in accordance with Section
358 of the Code, immediately after the Reorganization, the tax basis of the
Insured I Common Stock, Insured I Series F AMPS and Insured I Series G AMPS
received by the stockholders of Insured II in the Reorganization will be equal,
in the aggregate, to the tax basis of the Insured II Common Stock, Insured II
Series A AMPS and Insured II Series B AMPS surrendered in exchange; (vii) in
accordance with Section 1223 of the Code, a stockholder's holding period for the
Insured I
 
                                       54
<PAGE>   59
 
Common Stock, Insured I Series F AMPS and Insured I Series G AMPS will be
determined by including the period for which such stockholder held the Insured
II Common Stock, Insured II Series A AMPS or Insured II Series B AMPS exchanged
therefor, provided, that such Insured II shares were held as a capital asset;
(viii) in accordance with Section 1223 of the Code, Insured I's holding period
with respect to the Insured II assets transferred will include the period for
which such assets were held by Insured II; (ix) the payment of cash to Insured
II stockholders in lieu of fractional shares of Insured I will be treated as
though the fractional shares were distributed as part of the Reorganization and
then redeemed, with the result that such Insured II stockholders will have
short- or long-term capital gain or loss to the extent that the cash
distribution differs from the basis allocable to the Insured I fractional
shares; and (x) the taxable year of Insured II will end on the effective date of
the Reorganization and pursuant to Section 381(a) of the Code and regulations
thereunder, Insured I will succeed to and take into account certain tax
attributes of Insured II, such as earnings and profits, capital loss carryovers
and method of accounting.
 
     As noted in the discussion under "Comparison of the Funds--Tax Rules
Applicable to Insured I, Insured II and Their Stockholders", a Fund must
distribute annually at least 90% of its net taxable and tax-exempt income. A
distribution only will be counted for this purpose if it qualifies for the
dividends paid deduction under the Code. In the opinion of Brown & Wood, the
issuance of Insured I Series F AMPS and Insured I Series G AMPS pursuant to the
Reorganization in addition to the already existing Insured I Series A AMPS,
Series B AMPS, Series C AMPS, Series D AMPS and Series E AMPS will not cause
distributions on any series of AMPS to be treated as preferential dividends
ineligible for the dividends paid deduction. It is possible that the IRS may
assert that, because there are several series of AMPS, distributions on such
shares are preferential under the Code and therefore not eligible for the
dividends paid deduction. If the IRS successfully disallowed the dividends paid
deduction for dividends on the AMPS, Insured I could lose the special tax
treatment afforded RICs. In this case, dividends on the shares of AMPS would not
be exempt from Federal income tax. Additionally, Insured I would be subject to
the alternative minimum tax.
 
     Stockholders should consult their tax advisers regarding the effect of the
Reorganization in light of their individual circumstances. As the foregoing
relates only to Federal income tax consequences, stockholders also should
consult their tax advisers as to the foreign, state and local tax consequences
of the Reorganization.
 
     Status as a Regulated Investment Company. Both Insured I and Insured II
have elected and qualified for taxation as RICs under Sections 851-855 of the
Code, and after the Reorganization Insured I intends to continue to so qualify.

(a) The adjusted balances are presented as if the Reorganization had been
    consummated on April 30, 1996 and are for informational purposes only.
    Assumes distributions of undistributed net investment income and accrual of
    estimated Reorganization expenses of $217,000. No assurance can be given as
    to how many shares of Insured I Common Stock that Insured II stockholders
    will receive on the Exchange Date, and the foregoing should not be relied
    upon to reflect the number of shares of Insured I Common Stock that actually
    will be received on or after such date.
 
(b) Assumes the issuance of 16,288,002 shares of Insured I Common Stock and two
    newly-created series of AMPS each consisting of 2,400 shares in exchange for
    the net assets of Insured II. The number of shares of Common Stock issued
    was based on the net asset value of each Fund, net of distributions on April
    30, 1996.

                             ELECTION OF DIRECTORS
 
     At the Meetings, the Boards of Directors for Insured I and Insured II will
be elected to serve until the next Annual Meeting of Stockholders and until
their successors are elected and qualified. If the stockholders of both Insured
I and Insured II approve the Reorganization, then the Board of Directors of
Insured I elected at the Meeting will serve as the Board of combined fund, until
its next Annual Meeting of Stockholders. If the stockholders of either Insured I
or Insured II vote against the Reorganization, then the Board of Directors of
each Fund elected at the Meetings will continue to serve until the next Annual
Meeting of Stockholders of each Fund. It is intended that all properly executed
proxies will be voted (unless such authority has been withheld in the proxy) as
follows:
 
     With respect to the proxies of Insured I stockholders:
 
          (1) All proxies of the holders of shares of Insured I AMPS, voting
     separately as a class, will be voted in favor of the two persons designated
     as Directors to be elected by the holders of shares of Insured I AMPS; and
 
          (2) All proxies of the holders of shares of Insured I Common Stock and
     Insured I AMPS, voting together as a single class, will be voted in favor
     of the four persons designated as Directors to be elected by the holders of
     Insured I Common Stock and Insured I AMPS.
 
     With respect to the proxies of Insured II stockholders:
 
          (1) All proxies of the holders of shares of Insured II AMPS, voting
     separately as a class, will be voted in favor of the two persons designated
     as Directors to be elected by the holders of shares of Insured II AMPS; and
 
          (2) All proxies of the holders of shares of Insured II Common Stock
     and Insured II AMPS, voting together as a single class, will be voted in
     favor of the four persons designated as Directors to be elected by the
     holders of shares of Insured II Common Stock and Insured II AMPS.
 
     The Boards of Directors of Insured I and Insured II know 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 Boards of Directors may recommend.

COMMITTEE AND BOARD MEETINGS
 
     The Board of Directors of each Fund has a standing Audit Committee, which
consists of the Directors who are not "interested persons", as defined in the
Investment Company Act, of the Fund. The principal purpose of the Audit
Committee is to review the scope of the annual audit conducted by each Fund's
independent auditors and the evaluation by such auditors of the accounting
procedures followed by the Fund. The non-interested Directors have retained
independent legal counsel to assist them in connection with these duties.
Neither Board of Directors has a nominating committee. During the fiscal year
ended October 31, 1995, the Boards of Directors and the Audit Committees of
Insured I and Insured II each held four quarterly meetings. All of the Directors
of each Fund then in office attended at least 75% of the total number of
meetings of the Board of Directors and the total number of meetings held by all
of the committees of the Board on which they served during such period.
 
COMPLIANCE WITH SECTION 16(A) OF THE SECURITIES EXCHANGE ACT OF 1934
 
     Section 16(a) of the Securities Exchange Act of 1934, as amended (the
"Securities Exchange Act"), requires each Fund's officers, Directors and persons
who own more than ten percent of a registered class of the Fund's equity
securities, to file reports of ownership and changes in ownership on Forms 3, 4
and 5 with the Commission and the NYSE. Officers, Directors and greater than ten
percent stockholders are required by Commission regulations to furnish the Fund
with copies of all Forms 3, 4 and 5 that they file.
 
     Based solely on each Fund's review of the copies of such forms, and
amendments thereto, furnished to it during or with respect to its most recent
fiscal year, and written representations from certain reporting persons that
they were not required to file Forms 5 with respect to the most recent fiscal
year, each Fund believes that all of its officers, Directors, greater than ten
percent beneficial owners and other persons subject to Section 16 of the
Securities Exchange Act because of the requirements of Section 30 of the
Investment Company Act (i.e., any advisory board member, investment adviser or
affiliated person of the Fund's investment adviser), have complied with all
filing requirements applicable to them with respect to transactions during the
Fund's most recent fiscal year.
 
INTERESTED PERSONS
 
     Each Fund considers Mr. Zeikel to be an "interested person" of the Fund
within the meaning of Section 2(a)(19) of the Investment Company Act as a result
of the positions he holds with FAM and its affiliates. Mr. Zeikel is the
President of each Fund, the President of FAM and the President of MLAM.
 
COMPENSATION OF DIRECTORS
 
     FAM, the investment adviser for Insured I and Insured II, pays all
compensation of all officers of each Fund and all Directors of each Fund who are
affiliated with ML & Co. or its subsidiaries. Insured I pays each Director who
is not affiliated with FAM a fee of $4,000 per year plus $1,000 per regular
meeting attended, together with such Director's actual out-of-pocket expenses
relating to attendance at meetings. The Fund also pays each member of its Audit
Committee, which consists of all of the non-affiliated Directors, a fee of
$4,000 per year plus $750 per meeting attended, together with such Director's
out-of-pocket expenses relating to attendance at meetings. These fees and
expenses for the fiscal year ended October 31, 1995 aggregated $77,751 for
Insured I.
 
                                       63
<PAGE>   68
 
     Insured II pays each Director who is not affiliated with FAM a fee of
$2,500 per year plus $250 per regular meeting attended, together with such
Director's actual out-of-pocket expenses relating to attendance at meetings. The
Fund also pays each member of its Audit Committee, which consists of all of the
non-affiliated Directors, a fee of $500 per year plus $125 per meeting attended,
together with such Director's out-of-pocket expenses relating to attendance at
meetings. These fees and expenses for the fiscal year ended October 31, 1995
aggregated $22,606 for Insured II.
 
     The following table sets forth, for the fiscal year ended October 31, 1995,
compensation paid by Insured I to the non-affiliated Directors, and for the
calendar year ended December 31, 1995, the aggregate compensation paid by all
registered investment companies advised by FAM and its affiliate, MLAM
("FAM/MLAM Advised Funds"), to the non-affiliated Directors.

                       SELECTION OF INDEPENDENT AUDITORS
 
     The Board of Directors of Insured I, including a majority of the Directors
who are not "interested persons", as defined in the Investment Company Act, of
the Fund, has selected the firm of Deloitte & Touche LLP as independent
auditors, to audit the financial statements of Insured I for the current fiscal
year ending October 31, 1996. However, in the event that the Reorganization is
approved by the requisite number of stockholders of each Fund and the
Reorganization takes place prior to October 31, 1996, the Board of Directors of
Insured I, including a majority of the Directors who are not "interested
persons" of the Fund,
 
                                       65
<PAGE>   70
 
have selected the firm of Ernst & Young LLP as independent auditors, to audit
the financial statements of the combined fund for the fiscal year ending October
31, 1996.
 
     The Board of Directors of Insured II, including a majority of the Directors
who are not "interested persons" of the Fund, has selected the firm of Ernst &
Young LLP as independent auditors, to audit the financial statements of the Fund
for the current fiscal year ending October 31, 1996.
 
     The Funds know of no direct or indirect financial interest of such firms in
the Funds. Such appointment is subject to ratification or rejection by the
stockholders of the Funds. If the stockholders of both Insured I and Insured II
approve the Reorganization, then the independent auditors selected at the
Meetings for Insured I will serve as the independent auditors of the combined
fund until its next Annual Meeting of Stockholders. If the stockholders of
either Insured I or Insured II vote against the Reorganization, then the
independent auditors of each Fund selected at the Meetings will continue to
serve until the next Annual Meeting of Stockholders of each Fund. Unless a
contrary specification is made, the accompanying proxy will be voted in favor of
ratification of the selection of such auditors.
 
     Deloitte & Touche LLP also acts as independent auditors for ML & Co. and
all of its subsidiaries and for most other investment companies for which FAM or
MLAM acts as investment adviser. The fees received by Deloitte & Touche LLP from
these other entities are substantially greater, in the aggregate, than the total
fees received by it from Insured I. The Board of Directors of Insured I
considered the fact that Deloitte & Touche LLP has been retained as the
independent auditors of ML & Co. and the other entities described above in its
evaluation of the independence of Deloitte & Touche LLP with respect to Insured
I.
 
     Ernst & Young LLP also acts as independent auditors for several other
investment companies for which FAM or MLAM acts as investment adviser. The fees
received by Ernst & Young LLP from these other entities are substantially
greater, in the aggregate, than the total fees received by it from Insured II.
The Board of Directors of each of Insured I and Insured II considered the fact
that Ernst & Young LLP has been retained as the independent auditors of the
other entities described above in its evaluation of the independence of Ernst &
Young LLP with respect to Insured I or Insured II, as applicable.
 
     Representatives of Deloitte & Touche LLP or Ernst & Young LLP, as
applicable, are expected to be present at the Meetings and will have the
opportunity to make a statement if they so desire and to respond to questions
from stockholders.
 
                   INFORMATION CONCERNING THE ANNUAL MEETINGS
 
DATE, TIME AND PLACE OF MEETINGS
 
     The Meetings will be held on September 9, 1996 at the offices of MLAM, 800
Scudders Mill Road, Plainsboro, New Jersey at 10:45 A.M., New York time (for
Insured I) and 11:00 A.M., New York time (for Insured II).
 
SOLICITATION, REVOCATION AND USE OF PROXIES
 
     A stockholder executing and returning a proxy has the power to revoke it at
any time prior to its exercise by executing a superseding proxy or by submitting
a notice of revocation to the Secretary of Insured I or
 
                                       66
<PAGE>   71
 
Insured II, as the case may be. Although mere attendance at the Meetings will
not revoke a proxy, a stockholder present at the Meetings may withdraw his proxy
and vote in person.
 
     All shares represented by properly executed proxies, unless such proxies
previously have been revoked, will be voted at the Meetings in accordance with
the directions on the proxies; if no direction is indicated, the shares will be
voted "FOR" (i) the approval of the Agreement and Plan of Reorganization, (ii)
the election of Directors and (iii) the ratification of the selection of
Deloitte & Touche LLP or Ernst & Young LLP, as applicable, as independent
accountants.
 
     It is not anticipated that any matters other than (i) the adoption of the
Agreement and Plan of Reorganization, (ii) the election of Directors and (iii)
the ratification of the selection of Deloitte & Touche LLP or Ernst & Young LLP,
as applicable, will be brought before the Meetings. If, however, any other
business properly is brought before the Meetings, proxies will be voted in
accordance with the judgment of the persons designated on such proxies.
 
RECORD DATE AND OUTSTANDING SHARES
 
     Only holders of record of shares of Insured I Common Stock, Insured I AMPS,
Insured II Common Stock and Insured II AMPS at the close of business on the
Record Date are entitled to vote at the Meetings or any adjournment thereof. At
the close of business on the Record Date, there were 45,187,339 shares of
Insured I Common Stock, 12,800 shares of Insured I AMPS, 16,420,827 shares of
Insured II Common Stock and 4,800 shares of Insured II AMPS issued and
outstanding and entitled to vote.
 
SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT OF INSURED I AND
INSURED II
 
     To the knowledge of Insured I and Insured II, at the date hereof, no person
or entity owns beneficially 5% or more of the shares of any of the Insured I
Common Stock, the Insured I AMPS, the Insured II Common Stock or the Insured II
AMPS.
 
     On the Record Date, the Directors and officers of Insured I as a group (12
persons) owned an aggregate of less than 1% of the outstanding shares of Insured
I Common Stock and Insured I AMPS.
 
     On the Record Date, the Directors and officers of Insured II as a group (12
persons) owned an aggregate of less than 1% of the outstanding shares of Insured
II Common Stock and Insured II AMPS.
 
     On the Record Date, Mr. Zeikel, a Director and officer of each of the
Funds, and the other Directors and officers of each Fund owned an aggregate of
less than 1% of the outstanding shares of Common Stock of ML & Co.
 
VOTING RIGHTS AND REQUIRED VOTE
 
     For purposes of this Proxy Statement and Prospectus, each share of Insured
I Common Stock, Insured I AMPS, Insured II Common Stock and Insured II AMPS is
entitled to one vote. Approval of the Agreement and Plan of Reorganization
requires the affirmative vote of stockholders representing a majority of the
outstanding shares of Insured I Common Stock and Insured I AMPS, voting together
as a single class, and of the Insured I AMPS, voting separately as a class, as
well as the affirmative vote of stockholders representing a majority of the
outstanding shares of Insured II Common Stock and Insured II AMPS, voting
together as a single class, and of the Insured II AMPS, voting separately as a
class.
 
                                       67
<PAGE>   72
 
     Under Maryland law, stockholders of a registered investment company whose
shares are traded publicly on a national securities exchange, such as Insured
II, are not entitled to demand the fair value of their shares upon a transfer of
assets; therefore, the Insured II Common Stockholders will be bound by the terms
of the Reorganization, if approved at the Meetings. However, any Common
Stockholder of Insured II may sell his or her shares of Common Stock at any time
on the NYSE. Conversely, since the Insured II AMPS are not traded publicly on a
national securities exchange, shareholders of Insured II AMPS will be entitled
to appraisal rights upon the consummation of the Reorganization. As stockholders
of the corporation acquiring the assets of Insured II, neither holders of
Insured I Common Stock nor holders of Insured I AMPS are entitled to appraisal
rights under Maryland law.
 
     For purposes of each Meeting, a quorum consists of a majority of the shares
entitled to vote at the Meeting, present in person or by proxy. If, by the time
scheduled for each Meeting, a quorum of the applicable Fund's stockholders is
not present or if a quorum is present but sufficient votes in favor of the
Agreement and Plan of Reorganization are not received from the stockholders of
the applicable Fund, the persons named as proxies may propose one or more
adjournments of the Meeting to permit further solicitation of proxies from
stockholders. Any such adjournment will require the affirmative vote of a
majority of the shares of the applicable Fund present in person or by proxy and
entitled to vote at the session of the Meeting to be adjourned. The persons
named as proxies will vote in favor of any such adjournment if they determine
that adjournment and additional solicitation are reasonable and in the interests
of the applicable Fund's stockholders.
 
     With respect to the election of Directors, holders of shares of Insured I
AMPS are entitled to elect two Directors of Insured I and holders of shares of
Insured I Common Stock and Insured I AMPS, voting together as a single class,
are entitled to elect the remaining Directors of Insured I; similarly, holders
of shares of Insured II AMPS are entitled to elect two Directors of Insured II
and holders of shares of Insured II Common Stock and Insured II AMPS, voting
together as a single class, are entitled to elect the remaining Directors of
Insured II. Assuming a quorum is present, (x) election of the two Directors of
Insured I or Insured II, as the case may be, to be elected by the holders of
shares of Insured I AMPS or Insured II AMPS, respectively, voting separately as
a class, will require the affirmative vote of a majority of the votes cast by
the holders of that Fund's AMPS, represented at the Meetings and entitled to
vote; and (y) election of the remaining Directors of Insured I or Insured II, as
the case may be, will require the affirmative vote of a majority of the votes
cast by the holders of their respective Common Stock and AMPS, represented at
the Meetings and entitled to vote, voting together as a single class.
 
     Approval of the ratification of the selection of Deloitte & Touche LLP as
the independent auditors of Insured I (or, in the event that the Reorganization
is approved by the requisite number of stockholders of each Fund and the
Reorganization takes place prior to October 31, 1996, approval of Ernst & Young
LLP as the independent auditors of the combined fund) will require the
affirmative vote of a majority of the votes cast by the holders of Insured I
Common Stock and Insured I AMPS represented at the Meetings and entitled to
vote, voting together as a single class; similarly, approval of the ratification
of the selection of Ernst & Young LLP as the independent auditors of Insured II
will require the affirmative vote of a majority of the votes cast by the holders
of Insured II Common Stock and Insured II AMPS represented at the Meetings and
entitled to vote, voting together as a single class.

                             ADDITIONAL INFORMATION
 
     The expenses of preparation, printing and mailing of the enclosed form of
proxy, the accompanying Notice and this Proxy Statement and Prospectus will be
borne by Insured I, the surviving fund after the Reorganization, so as to be
borne equally and exclusively on a per share basis by the holders of Insured I
Common Stock and Insured II Common Stock.
 
     Insured I and Insured II likewise will reimburse banks, brokers and others
for their reasonable expenses in forwarding proxy solicitation materials to the
beneficial owners of shares of Insured I and Insured II and certain persons that
Insured I or Insured II may employ for their reasonable expenses in assisting in
the solicitation of proxies from such beneficial owners of shares of capital
stock of Insured I or Insured II.
 
     In order to obtain the necessary quorum at the Meetings (i.e., a majority
of the shares of each class of each Fund's securities entitled to vote at the
Meetings, present in person or by proxy), supplementary solicitation may be made
by mail, telephone, telegraph or personal interview by officers of the Fund. The
Funds also may hire proxy solicitors at the expense of Insured I. It is
anticipated that the cost of such supplementary solicitation, if any, will be
nominal.
 
     Broker-dealer firms, including Merrill Lynch, holding Fund shares in
"street name" for the benefit of their customers and clients will request the
instructions of such customers and clients on how to vote their shares on each
proposal before the Meetings. The Funds understand that, under the rules of the
NYSE, such broker-dealer firms may, without instructions from their customers
and clients, grant authority to the proxies designated to vote on the election
of a Board of Directors of each Fund to serve for the ensuing year (proposal 2)
and the ratification of the selection of Deloitte & Touche LLP or Ernst & Young
LLP, as applicable, as independent auditors for each Fund for the current fiscal
year (proposals 3 and 4) if no instructions have been received prior to the date
specified in the broker-dealer firm's request for voting instructions.
Broker-dealer firms, including Merrill Lynch, will not be permitted to grant
voting authority without instructions with respect to the approval of the
Agreement and Plan of Reorganization (proposal 1). The Funds will include shares
held of record by broker-dealers as to which such authority has been granted in
its tabulation of the total number of shares present for purposes of determining
whether the necessary quorum of shareholders of each Fund exists. Proxies which
are returned to a Fund but which are marked "abstain" or on which a
broker-dealer has declined to vote on any proposal ("broker non-votes") will be
counted as present for the purposes of determining a quorum. Merrill Lynch has
advised the Funds that it intends to exercise discretion over shares held in its
name for which no instructions have been received by voting such shares on
proposals 2, 3 and 4 (in the case of Insured I) in the same proportion as it has
voted such shares for which it has received instructions. However, abstentions
and broker non-votes will not be counted as votes cast. Abstentions and broker
non-votes will not have an effect on the vote on proposals 2, 3 and 4 (in the
case of Insured I); however, abstentions and broker non-votes will have the same
effect as a vote against proposal 1.
 
     This Proxy Statement and Prospectus does not contain all of the information
set forth in the registration statement and the exhibits relating thereto which
Insured I has filed with the Commission under the Securities Act and the
Investment Company Act, to which reference is hereby made.

                               LEGAL PROCEEDINGS
 
     On June 21, 1996, a purported class action titled Jack Green, et al. v.
Fund Asset Management, L.P., et al. was filed in the United States District
Court for the District of Massachusetts. Among the named defendants in the
action are seven of the leveraged closed-end municipal bond funds for which FAM
serves as the investment adviser (including Insured I and Insured II). In
addition to the named defendants, plaintiffs also purport to bring claims
against a defendant class consisting of all other publicly traded, closed-end
investment companies for which FAM serves as investment adviser and which, among
other things, have issued AMPS. The named plaintiffs, who claim to be investors
in the seven named funds, purport to bring the action on behalf of a class
consisting of all holders of the common stock of the subject funds.
 
     Plaintiffs allege that FAM and other affiliated defendants received
excessive compensation for managing the subject funds. Plaintiffs claim, among
other things, that the registration statements, annual reports and other
documents filed by the funds with the Commission were misleading because such
documents allegedly failed to disclose that proceeds arising from the issuance
of AMPS would be included in a fund's net assets for the purposes of calculating
the investment advisory fee payable to FAM. In addition, plaintiffs allege that
a conflict of interest existed because it would always be in the defendants'
interest to keep the funds fully leveraged to maximize the advisory fees and
collateral compensation notwithstanding adverse market conditions. Plaintiffs
also allege an additional conflict of interest arising from the receipt by such
affiliates of underwriting discounts, or other revenues in connection with the
sale of the AMPS by the funds. The complaint asserts claims under Sections 8(e),
34(b), 36(a) and 36(b) of the Investment Company Act and the common law.
Plaintiffs seek unspecified monetary damages as well as injunctive relief.
 
                                       70
<PAGE>   75
 
     The defendants believe that the plaintiffs' allegations are entirely
without merit and intend to defend the action vigorously. FAM has agreed to
indemnify the named defendant funds for any liabilities or expenses that they
may occur in connection with this litigation.
 
                                 LEGAL OPINIONS

Wood LLP will rely as to matters of Maryland law on the opinion of Wilmer,

INDEPENDENT AUDITORS' REPORT
 
The Board of Directors and Shareholders of
MuniYield Insured Fund, Inc.:
 
We have audited the accompanying statement of assets, liabilities and capital,
including the schedule of investments, of MuniYield Insured Fund, Inc. as of
October 31, 1995, the related statements of operations for the year then ended
and changes in net assets for each of the years in the two-year period then
ended, and the financial highlights for each of the years in the three-year
period then ended and the period March 27, 1992 (commencement of operations) to
October 31, 1992. 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 October
31, 1995 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 MuniYield Insured
Fund, Inc. as of October 31, 1995, the results of its operations, the changes in
its net assets, and the financial highlights for the respective stated periods
in conformity with generally accepted accounting principles.

NOTES TO FINANCIAL STATEMENTS

1. Significant Accounting Policies:
MuniYield Insured Fund, Inc. (the "Fund") is registered under the
Investment Company Act of 1940 as a non-diversified, closed-end
management investment company. 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 MYI. 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 most recent
bid price or yield equivalent as obtained by the Fund's pricing
service from dealers that make markets in such securities. Financial
futures contracts and options thereon, 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 of sixty days or less are valued at amortized
cost, which approximates market value. Securities 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, including valuations furnished by a pricing
service retained by the Fund, which may utilize a matrix system for
valuations. The procedures of the pricing service and its valuations
are reviewed by the officers of the Fund under the general
supervision of the Board of Directors.

(b) Derivative financial instruments--The Fund may engage in various
portfolio strategies to seek to increase its return by hedging its
portfolio against adverse movements in the debt markets. Losses may
arise due to changes in the value of the contract or if the
counterparty does not perform under the contract.

* Financial futures contracts--The 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.

* Options--The Fund is authorized to write covered call options and
purchase put options. When the Fund writes an option, an amount
equal to the premium received by the Fund is reflected as an asset
and an equivalent liability. The amount of the liability is
subsequently marked to market to reflect the current market value of
the option written.

When a security is purchased or sold through an exercise of an
option, the related premium paid (or received) is added to (or
deducted from) the basis of the security acquired, or deducted from
(or added to) the proceeds of the security sold. When an option
expires (or the Fund enters into a closing transaction), the Fund
realizes a gain or loss on the option to the extent of the premiums
received or paid (or gain or loss to the extent the cost of the
closing transaction exceeds the premium paid or received).

Written and purchased options are non-income producing investments.

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

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

(e) Deferred organization expenses and offering expenses--Deferred
organization expenses are amortized on a straight-line basis over a
five-year period. Direct expenses relating to the public offering of
the Common and Preferred Stock were charged to capital at time of
issuance.

(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. Distributions in excess of realized capital gains
are due primarily to differing tax treatments for futures transactions
and post-October losses.

2. Investment Advisory Agreement and
Transactions with Affiliates:
The Fund has entered into an Investment Advisory Agreement with Fund
Asset Management, L.P. ("FAM"). The general partner of FAM is
Princeton Services, Inc. ("PSI"), an indirect wholly-owned
subsidiary of Merrill Lynch & Co., Inc. ("ML & Co."), which is the
limited partner.

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 at an annual rate of 0.50% of
the Fund's average weekly net assets.

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, PSI, Merrill Lynch, Pierce, Fenner & Smith Inc.
("MLPF&S"), and/or ML & Co.

related to appreciated securities and $159,673 related to
depreciated securities. The aggregate cost of investments at October

4. Capital Stock Transactions:
The Fund is authorized to issue 200,000,000 shares of capital stock,
including Preferred Stock, par value $.10 per share, all of which
were initially classified as Common Stock. The Board of Directors is
authorized, however, to reclassify any unissued shares of capital
stock without approval of holders of Common Stock.

Common Stock
For the year ended October 31, 1995, shares issued and outstanding
remained constant at 45,187,339. At October 31, 1995, total paid-in
capital amounted to $634,751,837.

Preferred Stock
Auction Market Preferred Stock ("AMPS") are shares of Preferred
Stock of the Fund that entitle their holders to receive cash
dividends at an annual rate that may vary for the successive
dividend periods. The yields in effect at October 31, 1995 were as
follows: Series A, 3.77%; Series B, 3.77%; Series C, 3.77%; Series
D, 3.667%; and Series E, 3.77%.

A two-for-one stock split occurred on December 1, 1994. As a result,
as of October 31, 1995, there were 12,800 AMPS shares authorized,
issued and outstanding with a liquidation preference of $25,000 per
share, plus accumulated and unpaid dividends of $197,820.

The Fund pays commissions to certain broker-dealers at the end of
each auction at an annual rate ranging from 0.25% to 0.375%,
calculated on the proceeds of each auction. For the year ended
October 31, 1995, MLPF&S, an affiliate of FAM, earned $450,570 as
commissions.


5. Subsequent Event:
On November 13, 1995, the Fund's Board of Directors declared an
ordinary income dividend to Common Stock shareholders in the amount
of $0.077732 per share, payable on November 29, 1995, to
shareholders of record as of November 24, 1995.

NOTES TO FINANCIAL STATEMENTS

1. Significant Accounting Policies:
MuniYield Insured Fund, Inc. (the "Fund") is registered under the
Investment Company Act of 1940 as a non-diversified, closed-end
management investment company. These unaudited financial statements
reflect all adjustments which are, in the opinion of management,
necessary to a fair statement of the results for the interim period
presented. All such adjustments are of a normal recurring nature.
The Fund 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 MYI.
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 most recent
bid price or yield equivalent as obtained by the Fund's pricing
service from dealers that make markets in such securities. Financial
futures contracts and options thereon, 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 of sixty days or less are valued at amortized
cost, which approximates market value. Securities 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, including valuations furnished by a pricing
service retained by the Fund, which may utilize a matrix system for
valuations. The procedures of the pricing service and its valuations
are reviewed by the officers of the Fund under the general
supervision of the Board of Directors.

(b) Derivative financial instruments--The Fund may engage in various
portfolio strategies to seek to increase its return by hedging its
portfolio against adverse movements in the debt markets. Losses may
arise due to changes in the value of the contract or if the
counterparty does not perform under the contract.

* Financial futures contracts--The 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.

* Options--The Fund is authorized to write covered call options and
purchase put options. When the Fund writes an option, an amount
equal to the premium received by the Fund is reflected as an asset
and an equivalent liability. The amount of the liability is
subsequently marked to market to reflect the current market value of
the option written.

When a security is purchased or sold through an exercise of an
option, the related premium paid (or received) is added to (or
deducted from) the basis of the security acquired, or deducted from
(or added to) the proceeds of the security sold. When an option
expires (or the Fund enters into a closing transaction), the Fund
realizes a gain or loss on the option to the extent of the premiums
received or paid (or gain or loss to the extent the cost of the
closing transaction exceeds the premium paid or received).

Written and purchased options are non-income producing investments.

(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).

MuniYield Insured Fund, Inc.                                       April 30,1996

Interest income is recognized on the accrual basis. Discounts and market
premiums are amortized into interest income. Realized gains and losses on
security transactions are determined on the identified cost basis.

(e) Deferred organization expenses--Deferred organization expenses
are amortized on a straight-line basis over a five-year period.

(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. Distributions in excess of
realized capital gains are due primarily to differing tax treatments
for future transactions and post-October losses.

2. Investment Advisory Agreement and
Transactions with Affiliates:
The Fund has entered into an Investment Advisory Agreement with Fund
Asset Management, L.P. ("FAM"). The general partner of FAM is
Princeton Services, Inc. ("PSI"), an indirect wholly-owned
subsidiary of Merrill Lynch & Co., Inc. ("ML & Co."), which is the
limited partner.

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 at an annual rate of 0.50% of
the Fund's average weekly net assets.

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, PSI, Merrill Lynch, Pierce, Fenner & Smith Inc.
("MLPF&S"), and/or ML & Co.

3. Investments:
Purchases and sales of investments, excluding short-term securities,
for the six months ended April 30, 1996 were $454,588,870 and
$491,596,635, respectively.

Net realized and unrealized gains as of April 30, 1996 were as

</TABLE>

As of April 30, 1996, net unrealized appreciation for Federal income
tax purposes aggregated $33,944,410, of which $37,489,277 related to
appreciated securities and $3,544,867 related to depreciated
securities. The aggregate cost of April 30, 1996 for Federal income
tax purposes was $941,940,039.

4. Capital Stock Transactions:
The Fund is authorized to issue 200,000,000 shares of capital stock,
including Preferred Stock, par value $.10 per share, all of which
were initially classified as Common Stock. The Board of Directors is
authorized, however, to reclassify any unissued shares of capital
stock without approval of the holders of Common Stock.

Common Stock
For the six months ended April 30, 1996, shares issued and
outstanding remained constant at 45,187,339. At April 30, 1996,
total paid-in capital amounted to $634,751,837.

Preferred Stock
Auction Market Preferred Stock ("AMPS") are shares of Preferred
Stock of the Fund that entitle their holders to receive cash
dividends at an annual rate that may vary for the successive
dividend periods. The yields in effect at April 30, 1996 were as
follows: Series A, 3.65%; Series B, 3.62%; Series C, 3.63%; Series
D, 3.47%; and Series E, 3.85%.

As of April 30, 1996, there were 12,800 AMPS shares authorized,
issued and outstanding with a liquidation preference of $25,000 per
share.

The Fund pays commissions to certain broker-dealers at the end of
each auction at an annual rate ranging from 0.25% to 0.375%,
calculated on the proceeds of each auction. For the six months ended
April 30, 1996, MLPF&S, an affiliate of FAM, earned $228,545 as
commissions.

5. Subsequent Event:
On May 10, 1996, the Fund's Board of Directors declared an ordinary
income dividend to Common Stock shareholders in the amount of
$0.073902 per share, payable on May 30, 1996, to shareholders of
record as of May 21, 1996.

NOTES TO FINANCIAL STATEMENTS

1. Significant Accounting Policies:
MuniYield Insured Fund II, Inc. (the "Fund") is registered under the
Investment Company Act of 1940 as a non-diversified, closed-end
management investment company. 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 MTI. 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 most recent
bid price or yield equivalent as obtained by the Fund's pricing
service from dealers that make markets in such securities. Financial
futures contracts and options thereon, 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 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, including valuations furnished by a
pricing service retained by the Fund, which may utilize a matrix
system for valuations. The procedures of the pricing service and its
valuations are reviewed by the officers of the Fund under the
general supervision of the Board of Directors.

(b) Derivative financial instruments--The Fund may engage in various
portfolio strategies to seek to increase its return by hedging its
portfolio against adverse movements in the debt markets. Losses may
arise due to changes in the value of the contract or if the
counterparty does not perform under the contract.

* Financial futures contracts--The 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.

* Options--The Fund is authorized to write covered call options and
purchase put options. When the Fund writes an option, an amount
equal to the premium received by the Fund is reflected as an asset
and an equivalent liability. The amount of the liability is
subsequently marked to market to reflect the current market value of
the option written.

When a security is purchased or sold through an exercise of an
option, the related premium paid (or received) is added to (or
deducted from) the basis of the security acquired, or deducted from
(or added to) the proceeds of the security sold. When an option
expires (or the Fund enters into a closing transaction), the Fund
realizes a gain or loss on the option to the extent of the premiums
received or paid (or gain or loss to the extent the cost of the
closing transaction exceeds the premium paid or received).

Written and purchased options are non-income producing investments.

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

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

(e) Deferred organization expenses--Deferred organization expenses
are amortized on a straight-line basis over a five-year period.
Direct expenses relating to the public offering of the Common and
Preferred Stock were charged to capital at the time of issuance.

NOTES TO FINANCIAL STATEMENTS (concluded)


(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. Distributions in excess of
realized capital gains are due primarily to differing tax treatments
for futures transactions and post-October losses.

(g) Reclassification--Generally accepted accounting principles
require that certain components of net assets be reclassified to
reflect permanent differences between financial reporting and tax
purposes. Accordingly, current year's permanent book/tax differences
of $5,954 have been reclassified from accumulated net realized
capital losses to undistributed net investment income. These
reclassifications have no effect on net assets or net asset value
per share.


2. Investment Advisory Agreement and
Transactions with Affiliates:
The Fund has entered into an Investment Advisory Agreement with Fund
Asset Management, L.P. ("FAM"). The general partner of FAM is
Princeton Services, Inc. ("PSI"), an indirect wholly-owned
subsidiary of Merrill Lynch & Co., Inc. ("ML & Co."), which is the
limited partner.

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 at an annual rate of 0.50% of
the Fund's average weekly net assets.

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, PSI, Merrill Lynch, Pierce, Fenner & Smith Inc.
("MLPF&S"), and/or ML & Co.


3. Investments:
Purchases and sales of investments, excluding short-term securities,
for the year ended October 31, 1995 were $226,613,801 and
$214,964,056, respectively.

Net realized and unrealized gains (losses) as of October 31, 1995
were as follows:

As of October 31, 1995, net unrealized appreciation for Federal
income tax purposes aggregated $19,580,164, of which $19,753,121
related to appreciated securities and $172,957 related to
depreciated securities. The aggregate cost of investments at October
31, 1995 for Federal income tax purposes was $356,835,346.

4. Capital Stock Transactions:
The Fund is authorized to issue 200,000,000 shares of capital stock,
including Preferred Stock, par value $.10 per share, all of which
were initially classified as Common Stock. The Board of Directors is
authorized, however, to reclassify any unissued shares of capital
stock without approval of holders of Common Stock.

Common Stock
For the year ended October 31, 1995, shares issued and outstanding
remained constant at 16,420,827. At October 31, 1995, total paid-in
capital amounted to $230,207,408.

Preferred Stock
Auction Market Preferred Stock ("AMPS") are shares of Preferred
Stock of the Fund that entitle their holders to receive cash
dividends at an annual rate that may vary for the successive
dividend periods. The yields in effect at April 30, 1995 were 3.75%
for Series A and 3.75% for Series B.

A two-for-one stock split occurred on December 1, 1994. As a result,
as of October 31, 1995, there were 4,800 AMPS shares authorized,
issued and outstanding with a liquidation preference of $25,000 per
share, plus accumulated and unpaid dividends of $147,634.

The Fund pays commissions to certain broker-dealers at the end of
each auction at an annual rate ranging from 0.25% to 0.375%,
calculated on the proceeds of each auction. For the year ended
October 31, 1995, MLPF&S, an affiliate of FAM, earned $174,972 as
commissions.


5. Subsequent Event:
On November 13, 1995, the Fund's Board of Directors declared an
ordinary income dividend to Common Stock shareholders in the amount
of $0.075475 per share, payable on November 29, 1995 to shareholders
of record as of November 24, 1995.

NOTES TO FINANCIAL STATEMENTS

1. Significant Accounting Policies:
MuniYield Insured Fund II, Inc. (the "Fund") is registered under the
Investment Company Act of 1940 as a non-diversified, closed-end
management investment company. These unaudited financial statements
reflect all adjustments which are, in the opinion of management,
necessary to a fair statement of the results for the interim period
presented. All such adjustments are of a normal recurring nature.
The Fund 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 MTI.
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 most recent
bid price or yield equivalent as obtained by the Fund's pricing
service from dealers that make markets in such securities. Financial
futures contracts and options thereon, 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 of sixty days or less are valued at amortized
cost, which approximates market value. Securities 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, including valuations furnished by a pricing
service retained by the Fund, which may utilize a matrix system for
valuations. The procedures of the pricing service and its valuations
are reviewed by the officers of the Fund under the general
supervision of the Board of Directors.

(b) Derivative financial instruments--The Fund may engage in various
portfolio strategies to seek to increase its return by hedging its
portfolio against adverse movements in the debt markets. Losses may
arise due to changes in the value of the contract or if the
counterparty does not perform under the contract.

* Financial futures contracts--The 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.

* Options--The Fund is authorized to write covered call options and
purchase put options. When the Fund writes an option, an amount
equal to the premium received by the Fund is reflected as an asset
and an equivalent liability. The amount of the liability is
subsequently marked to market to reflect the current market value of
the option written.

When a security is purchased or sold through an exercise of an
option, the related premium paid (or received) is added to (or
deducted from) the basis of the security acquired, or deducted from
(or added to) the proceeds of the security sold. When an option
expires (or the Fund enters into a closing transaction), the Fund
realizes a gain or loss on the option to the extent of the premiums
received or paid (or gain or loss to the extent the cost of the
closing transaction exceeds the premium paid or received).

Written and purchased options are non-income producing investments.

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

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

NOTES TO FINANCIAL STATEMENTS (concluded)


(e) Deferred organization expenses--Deferred organization expenses
are amortized on a straight-line basis over a five-year period.

(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. Distributions in excess of
realized capital gains are due primarily to differing tax treatments
for futures transactions and post-October losses.


2. Investment Advisory Agreement and
Transactions with Affiliates:
The Fund has entered into an Investment Advisory Agreement with Fund
Asset Management, L.P. ("FAM"). The general partner of FAM is
Princeton Services, Inc. ("PSI"), an indirect wholly-owned
subsidiary of Merrill Lynch & Co., Inc. ("ML & Co."), which is the
limited partner.

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 at an annual rate of 0.50% of
the Fund's average weekly net assets.

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, PSI, Merrill Lynch, Pierce, Fenner & Smith Inc.
("MLPF&S"), and/or ML & Co.


3. Investments:
Purchases and sales of investments, excluding short-term securities,
for the six months ended April 30, 1996 were $142,111,759 and
$155,364,418, respectively.

                      AGREEMENT AND PLAN OF REORGANIZATION
 
     THIS AGREEMENT AND PLAN OF REORGANIZATION (this "Agreement") is made as of
the      day of           , 1996, by and between MuniYield Insured Fund, Inc., a
Maryland corporation ("Insured I"), and MuniYield Insured Fund II, Inc., a
Maryland corporation ("Insured II").
 
                             PLAN OF REORGANIZATION
 
     The reorganization will comprise (a) the acquisition by Insured I of all of
the assets, and the assumption by Insured I of all of the liabilities, of
Insured II in exchange solely for an equal aggregate value of newly-issued
shares of (i) common stock, par value $.10 per share, of Insured I ("Insured I
Common Stock"), (ii) auction market preferred stock, with a liquidation
preference of $25,000 per share plus an amount equal to accumulated but unpaid
dividends thereon (whether or not earned or declared) to be designated Series F,
of Insured I ("Insured I Series F AMPS"), and (iii) auction market preferred
stock, with a liquidation preference of $25,000 per share plus an amount equal
to accumulated but unpaid dividends thereon (whether or not earned or declared)
to be designated Series G, of Insured I ("Insured I Series G AMPS"), and (b) the
subsequent distribution to Insured II stockholders of (x) all of the Insured I
Common Stock received by Insured II in exchange for their shares of common
stock, par value $.10 per share, of Insured II ("Insured II Common Stock"), (y)
all of the Insured I Series F AMPS received by Insured II in exchange for their
shares of auction market preferred stock, with a liquidation preference of
$25,000 per share plus an amount equal to accumulated but unpaid dividends
thereon (whether or not earned or declared) designated Series A, of Insured II
("Insured II Series A AMPS"), and (z) all of the Insured I Series G AMPS
received by Insured II in exchange for their shares of auction market preferred
stock, with a liquidation preference of $25,000 per share plus an amount equal
to accumulated but unpaid dividends thereon (whether or not earned or declared)
designated Series B, of Insured II ("Insured II Series B AMPS" and, together
with the Insured II Series A AMPS, the "Insured II AMPS"), all upon and subject
to the terms hereinafter set forth (collectively, the "Reorganization").
 
     In the course of the Reorganization, Insured I Common Stock, Insured I
Series F AMPS and Insured I Series G AMPS will be distributed to Insured II
stockholders as follows: (i) each holder of Insured II Common Stock will be
entitled to receive a number of shares of Insured I Common Stock equal to the
aggregate net asset value of the Insured II Common Stock owned by such
stockholder on the Exchange Date (as defined in Section 7(a) of this Agreement);
(ii) each holder of Insured II Series A AMPS will be entitled to receive a
number of shares of Insured I Series F AMPS equal to the aggregate liquidation
preference (and aggregate value) of the Insured II Series A AMPS owned by such
stockholder on the Exchange Date; and (iii) each holder of Insured II Series B
AMPS will be entitled to receive a number of shares of Insured I Series G AMPS
equal to the aggregate liquidation preference (and aggregate value) of the
Insured II Series B AMPS owned by such stockholder on the Exchange Date. In
consideration therefor, on the Exchange Date Insured I shall acquire all of the
assets of Insured II and shall assume all of Insured II'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)(1)(C) of the Internal
Revenue Code of 1986, as amended (the "Code"), and any successor provision.
 
                                       I-1
<PAGE>   153
 
     Prior to the Exchange Date, Insured II shall declare a dividend or
dividends which, together with all such previous dividends, shall have the
effect of distributing to its stockholders all of its net investment company
taxable income for the period from November 1, 1995 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, realized for the period from
November 1, 1995 to and including the Exchange Date. In this regard, the last
dividend period for the Insured II Series A AMPS and the Insured II Series B
AMPS prior to the Exchange Date may be shorter than the dividend period for such
AMPS determined as set forth in the applicable Articles Supplementary.
 
     Separate Articles Supplementary to Insured I's Articles of Incorporation
establishing the powers, rights and preferences of the Insured I Series F AMPS
and the Insured I Series G AMPS will have been filed with the State Department
of Assessments and Taxation of Maryland (the "Maryland Department") prior to the
closing of the Reorganization.
 
     As promptly as practicable after the liquidation of Insured II pursuant to
the Reorganization, Insured II 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, Insured I and Insured II hereby agree as follows:
 
 1. REPRESENTATIONS AND WARRANTIES OF INSURED I.
 
     Insured I represents and warrants to, and agrees with, Insured II that:
 
          (a) Insured I 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 carry out this Agreement. Insured
     I 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) Insured I is duly registered under the 1940 Act as a
     non-diversified, closed-end management investment company (File No.
     811-6540), and such registration has not been revoked or rescinded and is
     in full force and effect. Insured I has elected and qualified for the
     special tax treatment afforded regulated investment companies ("RICs")
     under Sections 851-855 of the Code at all times since its inception, and
     intends to continue to so qualify both until consummation of the
     Reorganization and thereafter.
 
          (c) Insured I 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.
 
          (d) Insured II has been furnished with Insured I's Annual Report to
     Stockholders for the year ended October 31, 1995, and the audited financial
     statements appearing therein, having been examined
 
                                       I-2
<PAGE>   154
 
     by Deloitte & Touche LLP, independent public accountants, fairly present
     the financial position of Insured I as of the respective dates indicated,
     in conformity with generally accepted accounting principles applied on a
     consistent basis.
 
          (e) Insured II has been furnished with Insured I's Semi-Annual Report
     to Stockholders for the six months ended April 30, 1996, and the unaudited
     financial statements appearing therein fairly present the financial
     position of Insured I as of the respective dates indicated, in conformity
     with generally accepted accounting principles applied on a consistent
     basis.
 
          (f) An unaudited statement of assets, liabilities and capital of
     Insured I and an unaudited schedule of investments of Insured I, each as of
     the Valuation Time (as defined in Section 3(d) of this Agreement), will be
     furnished to Insured II at or prior to the Exchange Date for the purpose of
     determining the number of shares of Insured I Common Stock, Insured I
     Series F AMPS and Insured I Series G AMPS to be issued pursuant to Section
     4 of this Agreement; each will fairly present the financial position of
     Insured I as of the Valuation Time in conformity with generally accepted
     accounting principles applied on a consistent basis.
 
          (g) There are no material legal, administrative or other proceedings
     pending or, to the knowledge of Insured I, threatened against Insured I
     which assert liability on the part of Insured I or which materially affect
     its financial condition or its ability to consummate the Reorganization.
     Insured I 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) Insured I 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, except insofar as Insured I and Insured II have
     mutually agreed to amend such contract or other commitment or obligation to
     cure any potential violation as a condition precedent to the
     Reorganization.
 
          (i) There are no material contracts outstanding to which Insured I is
     a party that have not been disclosed in the N-14 Registration Statement (as
     defined in subsection (l) below) or will not otherwise be disclosed to
     Insured II prior to the Valuation Time.
 
          (j) Insured I has no known liabilities of a material amount,
     contingent or otherwise, other than those shown on Insured I's statements
     of assets, liabilities and capital referred to above, those incurred in the

     Stockholders for the year ended October 31, 1995, and the audited financial
     statements appearing therein, having been examined by Ernst & Young LLP,

     provisions of any Federal, state or local law or regulation or
     administrative ruling relating to any aspect of its business.
 
          (i) There are no material contracts outstanding to which Insured II is

     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, except insofar as Insured I and Insured II have
     mutually agreed to amend such contract or other commitment or obligation to
     cure any potential violation as a condition precedent to the
     Reorganization.
 
          (k) Insured II has no known liabilities of a material amount,

     received by it, up to and including the taxable year in which the Exchange
     Date occurs. All tax liabilities of Insured II have adequately been
     provided for on its books, and no tax deficiency or liability of Insured II
     has been asserted and no question with respect thereto has been raised by

     and marketable title to all of the Investments, and Insured I 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).
 
          (n) No consent, approval, authorization or order of any court or
     governmental authority is required for the consummation by Insured II of
     the Reorganization, except such as may be required under the 1933 Act, the

     Agreement and on the Exchange Date, insofar as it relates to Insured II (i)

     (a) Subject to receiving the requisite approvals of the stockholders of
each of Insured I and Insured II and to the other terms and conditions contained
herein, Insured II agrees to convey, transfer and deliver to Insured I for the
benefit of Insured I, and Insured I agrees to acquire from Insured II for the
benefit of Insured I, on the Exchange Date all of the Investments (including

and assume all of the liabilities of Insured II, in exchange solely for that

Agreement, as soon as practicable after the Exchange Date Insured II will
distribute all shares of Insured I Common Stock, Insured I Series F AMPS and
Insured I Series G AMPS received by it to its stockholders in exchange for their
corresponding shares of Insured II Common Stock, Insured II Series A AMPS and

AMPS prior to the Exchange Date may be shorter than the dividend period for such

<PAGE>   159
 
     (c) Insured II will pay, or cause to be paid, to Insured I any interest it
receives on or after the Exchange Date with respect to the Investments
transferred to Insured I hereunder.
 
     (d) The Valuation Time shall be 4:15 P.M., New York time, on           ,
1996, or such earlier or later day and time as mutually may be agreed upon in
writing (the "Valuation Time").
 
     (e) Insured I will acquire all of the assets of, and assume all of the

 4. ISSUANCE AND VALUATION OF INSURED I COMMON STOCK, INSURED I SERIES F AMPS
    AND INSURED I SERIES G AMPS IN THE REORGANIZATION.
 
     Full shares of Insured I Common Stock, Insured I Series F AMPS and Insured
I Series G AMPS 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 Insured II acquired in the Reorganization determined as
hereinafter provided, reduced by the amount of liabilities of Insured II assumed
by Insured I, shall be issued by Insured I in exchange for such assets of
Insured II, plus cash in lieu of fractional shares. The net asset value of
Insured I and Insured II shall be determined as of the Valuation Time in
accordance with the procedures described in (i) the prospectus of Insured I,
dated March 20, 1992, relating to the Insured I Common Stock and (ii) the
prospectus of Insured I, dated May 18, 1992, relating to the Insured I AMPS, and
no formula will be used to adjust the net asset value so determined of either
Insured I or Insured II 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 Insured II to be transferred to
Insured I shall be determined by Insured I pursuant to the procedures utilized
by Insured I in valuing its own assets and determining its own liabilities for
purposes of the Reorganization. Such valuation and determination shall be made
by Insured I in cooperation with Insured II and shall be confirmed in writing by
Insured I to Insured II. The net asset value per share of the Insured I Common
Stock and the liquidation preference per share of the Insured I Series F AMPS
and Insured I Series G AMPS shall be determined in accordance with such
procedures and Insured I shall certify the computations involved. Insured I
shall issue to Insured II separate certificates or share deposit receipts for
the Insured I Common Stock, the Insured I Series F AMPS and the Insured I Series
G AMPS, each registered in the name of Insured II. Insured II then shall
distribute the Insured I Common Stock, the
 
                                       I-8
<PAGE>   160
 
Insured I Series F AMPS and the Insured I Series G AMPS to its corresponding
stockholders of Insured II Common Stock, Insured II Series A AMPS and Insured II
Series B AMPS by redelivering the certificates or share deposit receipts
evidencing ownership of (i) the Insured I Common Stock to State Street Bank and
Trust Company, as the transfer agent and registrar for the Insured I Common
Stock and (ii) the Insured I Series F AMPS and the Insured I Series G AMPS to
IBJ Schroder Bank and Trust Company, as the transfer agent and registrar for the
Insured I Series F AMPS and the Insured I Series G AMPS. With respect to any
Insured II stockholder holding certificates evidencing ownership of either the
Insured II Common Stock, the Insured II Series A AMPS or the Insured II Series B
AMPS as of the Exchange Date, and subject to Insured I being informed thereof in
writing by Insured II, Insured I will not permit such stockholder to receive new
certificates evidencing ownership of the Insured I Common Stock, Insured I
Series F AMPS or Insured I Series G AMPS, exchange Insured I Common Stock,
Insured I Series F AMPS or Insured I Series G AMPS 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 Insured I Common Stock, Insured I Series F AMPS or Insured I Series
G AMPS, in any case, until notified by Insured II or its agent that such
stockholder has surrendered his or her outstanding certificates evidencing
ownership of the Insured II Common Stock, the Insured II Series A AMPS or the
Insured II Series B AMPS or, in the event of lost certificates, posted adequate
bond. Insured II, at its own expense, will request its stockholders to surrender
their outstanding certificates evidencing ownership of the Insured II Common
Stock, the Insured II Series A AMPS or the Insured II Series B AMPS, as the case
may be, or post adequate bond therefor.
 
     Dividends payable to holders of record of shares of Insured I Common Stock,
Insured I Series F AMPS and Insured I Series G AMPS, as the case may be, as of
any date after the Exchange Date and prior to the exchange of certificates by
any stockholder of Insured II shall be payable to such stockholder without
interest; however, such dividends shall not be paid unless and until such
stockholder surrenders his or her stock certificates of Insured II for exchange.
 
     No fractional shares of Insured I Common Stock will be issued to holders of
Insured II Common Stock. In lieu thereof, Insured I's transfer agent, State
Street Bank and Trust Company, will aggregate all fractional shares of Insured I
Common Stock and sell the resulting full shares on the New York Stock Exchange
at the current market price for shares of Insured I for the account of all
holders of fractional interests, and each such holder will receive such holder's
pro rata share of the proceeds of such sale upon surrender of such holder's
Insured II Common Stock certificates.
 
 5. PAYMENT OF EXPENSES.
 
     (a) Insured I 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 a memorandum to the
independent Directors of each of the Funds, the N-14 Registration Statement and
a private letter ruling request to the IRS, expenses incurred in connection with
the deregistration and dissolution of Insured II and the fees of special counsel
to the Reorganization. Such fees and expenses shall include legal, accounting

exchange fees, rating agency fees, portfolio transfer taxes (if any), and any
similar expenses incurred in connection with the Reorganization. Neither Insured
I nor Insured II shall pay any expenses of its respective stockholders arising

otherwise dispose of the assets of Insured II to be acquired in the
Reorganization, except for dispositions made in the ordinary course of business.
 
     (g) Insured I and Insured II 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. Insured I agrees to retain for a period of ten (10) years following the

other documents relating to tax matters of Insured II for its taxable period
first ending after the Exchange Date and for all prior taxable periods. Any

preparation and filing of said tax returns and Forms 1099 after the Exchange
Date shall be borne by Insured I.
 
     (h) Insured I and Insured II each agrees to mail to each of its respective
stockholders of record entitled to vote at the annual meeting of stockholders at

 8. INSURED I CONDITIONS.
 
     The obligations of Insured I 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
     two-thirds of the members of the Boards of Directors of Insured I and
 
                                      I-11
<PAGE>   163
 
     Insured II and by the affirmative vote of (i) the holders of (a) a majority
     of the Insured II Common Stock and Insured II AMPS, voting together as a
     single class, and (b) a majority of the Insured II AMPS, voting separately
     as a class, in each case issued and outstanding and entitled to vote
     thereon; and (ii) the holders of (x) a majority of the Insured II Common
     Stock and the Insured II AMPS, voting together as a single class, and (y) a
     majority of the Insured II AMPS, voting separately as a class, in each case
     issued and outstanding and entitled to vote thereon; and further that (iii)
     Insured I shall have delivered to Insured II a copy of the resolution
     approving this Agreement adopted by Insured I's Board of Directors, and a
     certificate setting forth the vote of Insured I's stockholders obtained,
     each certified by the Secretary of Insured I; and (iv) Insured II shall
     have delivered to Insured I a copy of the resolution approving this
     Agreement adopted by Insured II's Board of Directors, and a certificate
     setting forth the vote of Insured II's stockholders obtained, each
     certified by the Secretary of Insured II.
 
          (b) That Insured II shall have furnished to Insured I a statement of
     Insured II'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 Insured II's behalf by its President
     (or any Vice President) and its Treasurer, and a certificate of both such
     officers, dated the Exchange Date, certifying that as of the Valuation Time
     and as of the Exchange Date there has been no material adverse change in
     the financial position of Insured II since October 31, 1995, other than
     changes in the Investments since that date or changes in the market value
     of the Investments.
 
          (c) That Insured II shall have furnished to Insured I a certificate
     signed by Insured II'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 Insured II made in
     this Agreement are true and correct in all material respects with the same
     effect as if made at and as of such dates and Insured II 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.
 
          (d) That Insured II shall have delivered to Insured I a letter from
     Ernst & Young LLP, dated the Exchange Date, stating that such firm has
     performed a limited review of the Federal, state and local income tax
     returns of Insured II for the period ended October 31, 1995 (which returns
     originally were prepared and filed by Insured II), 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 Insured II for the
     period covered thereby; and that for the period from November 1, 1995 to
     and including the Exchange Date and for any taxable year of Insured II
     ending upon the liquidation of Insured II, 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 November 1, 1995 to and including the Exchange
     Date and for the final taxable year of Insured II ending upon liquidation
     or that Insured II had not qualified as a regulated investment company for
     Federal income tax purposes for the period from November 1, 1995 through
     liquidation of Insured II.

<PAGE>   164
 
          (e) That there shall not be any material litigation pending with
     respect to the matters contemplated by this Agreement.
 
          (f) That Insured I shall have received an opinion of Brown & Wood LLP,
     as counsel to both Insured I and Insured II, in form and substance
     satisfactory to Insured I and dated the Exchange Date, to the effect that
     (i) each of Insured I and Insured II is a corporation duly organized,
     validly existing and in good standing in conformity with the laws of the
     State of Maryland; (ii) the Insured I Common Stock, Insured I Series F AMPS
     and Insured I Series G AMPS to be issued pursuant to this Agreement are
     duly authorized and, upon delivery, will be validly issued and outstanding
     and fully paid and nonassessable by Insured I, and no stockholder of
     Insured I has any preemptive right to subscription or purchase in respect
     thereof (pursuant to the Articles of Incorporation, as amended, or the
     by-laws of Insured I or, to the best of such counsel's knowledge,
     otherwise); (iii) this Agreement has been duly authorized, executed and
     delivered by each of Insured I and Insured II, and represents a valid and
     binding contract, enforceable in accordance with its terms, except as
     enforceability may be limited by bankruptcy, insolvency, reorganization or
     other similar laws pertaining to the enforcement of creditors' rights
     generally and equitable principles; (iv) Insured II 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, Insured II will have duly transferred such assets and
     liabilities in accordance with this Agreement; (v) to the best of such
     counsel's knowledge, no consent, approval, authorization or order of any
     United States federal or Maryland state court or governmental authority is
     required for the consummation by Insured I and Insured II of the
     Reorganization, except such as have been obtained under the 1933 Act, the
     1934 Act and the 1940 Act and the published rules and regulations of the
     Commission thereunder and under Maryland law and such as may be reserved
     under state securities or blue sky laws; (vi) the N-14 Registration
     Statement has become effective under the 1933 Act, no stop order suspending
     the effectiveness of the N-14 Registration Statement has been issued and no
     proceedings for that purpose have been instituted or are pending or
     contemplated under the 1933 Act, and the N-14 Registration Statement, and
     each amendment or supplement thereto, as of their respective effective
     dates, appear on their face to be appropriately responsive in all material
     respects to the requirements of the 1933 Act, the 1934 Act and the 1940 Act
     and the published rules and regulations of the Commission thereunder; (vii)
     the descriptions in the N-14 Registration Statement of statutes, legal and
     governmental proceedings and contracts and other documents are accurate and
     fairly present the information required to be shown; (viii) such counsel do
     not know of any statutes, legal or governmental proceedings or contracts or
     other documents related to the Reorganization of a character required to be
     described in the N-14 Registration Statement which are not described
     therein or, if required to be filed, filed as required; (ix) the execution
     and delivery of this Agreement does not, and the consummation of the
     Reorganization will not, violate any material provision of the Articles of
     Incorporation, as amended, the by-laws, as amended, or any agreement (known
     to such counsel) to which either Insured I or Insured II is a party or by
     which either Insured I or Insured II is bound, except insofar as the
     parties have agreed to amend such provision as a condition precedent to the
     Reorganization; (x) neither Insured I nor Insured II, to the knowledge of
     such counsel, is 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 each has so qualified or the
     failure so to qualify would not have a material adverse effect on Insured
     I, Insured II, or their respective stockholders; (xi) to the best of such
     counsel's knowledge, no material suit, action or legal or administrative
     proceeding is pending or threatened against Insured I or Insured II, the
 
                                      I-13
<PAGE>   165
 
     unfavorable outcome of which would materially adversely affect Insured I or
     Insured II; and (xii) all corporate actions required to be taken by Insured
     I and Insured II to authorize this Agreement and to effect the
     Reorganization have been duly authorized by all necessary corporate actions
     on the part of Insured I and Insured II. Such opinion also shall state that
     (x) while such counsel cannot make any representation as to the accuracy or
     completeness of statements of fact in the N-14 Registration Statement or
     any amendment or supplement thereto, nothing has come to 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 state any
     material fact required to be stated therein or necessary to make the
     statements therein not misleading; and (2) the prospectus included in the
     N-14 Registration Statement contained any untrue statement of a material
     fact or omitted to state any material fact necessary to make the statements
     therein, in the light of the circumstances under which they were made, not
     misleading; and (y) such counsel do not express any opinion or belief as to
     the financial statements, other financial data, statistical data or
     information relating to Insured I or Insured II contained or incorporated
     by reference in the N-14 Registration Statement. In giving the opinion set
     forth above, Brown & Wood LLP may state that it is relying on certificates
     of officers of Insured I and Insured II with regard to matters of fact and
     certain certificates and written statements of governmental officials with
     respect to the good standing of Insured I and Insured II and on the opinion
     of Wilmer, Cutler & Pickering as to matters of Maryland law.
 
          (g) That Insured I shall have received a private letter ruling from
     the IRS, to the effect that for Federal income tax purposes (i) the
     transfer of all of the Investments of Insured II to Insured I in exchange
     solely for Insured I Common Stock, Insured I Series F AMPS and Insured I
     Series G AMPS as provided in this Agreement will constitute a
     reorganization within the meaning of Section 368(a)(1)(C) of the Code, and
     Insured I and Insured II will each be deemed a "party" to a Reorganization
     within the meaning of Section 361(b) of the Code; (ii) in accordance with
     Section 361(a) of the Code, no gain or loss will be recognized to Insured
     II as a result of the Reorganization or on the distribution of Insured I
     Common Stock, Insured I Series F AMPS and Insured I Series G AMPS to
     Insured II stockholders under Section 361(c)(1) of the Code; (iii) under
     Section 1032 of the Code, no gain or loss will be recognized to Insured I
     as a result of the Reorganization; (iv) in accordance with Section
     354(a)(1) of the Code, no gain or loss will be recognized to the
     stockholders of Insured II on the receipt of Insured I Common Stock,
     Insured I Series F AMPS and Insured I Series G AMPS in exchange for their
     corresponding Insured II Common Stock, Insured II Series A AMPS and Insured
     II Series B AMPS (except to the extent that Insured II stockholders receive
     cash representing an interest in fractional shares of Insured I in the
     Reorganization); (v) in accordance with Section 362(b) of the Code, the tax
     basis of the Insured II assets in the hands of Insured I will be the same
     as the tax basis of such assets in the hands of Insured II immediately
     prior to the consummation of the Reorganization; (vi) in accordance with
     Section 358 of the Code, immediately after the Reorganization, the tax
     basis of the Insured I Common Stock, Insured I Series F AMPS and Insured I
     Series G AMPS received by the stockholders of Insured II in the
     Reorganization will be equal, in the aggregate, to the tax basis of the
     Insured II Common Stock, Insured II Series A AMPS and Insured II Series B
     AMPS surrendered in exchange; (vii) in accordance with Section 1223 of the
     Code, a stockholder's holding period for the Insured I Common Stock,
     Insured I Series F AMPS and Insured I Series G AMPS will be determined by
     including the period for which such stockholder held the Insured II Common
     Stock, Insured II
 
                                      I-14
<PAGE>   166
 
     Series A AMPS and Insured II Series B AMPS exchanged therefor, provided,
     that such Insured II shares were held as a capital asset; (viii) in
     accordance with Section 1223 of the Code, Insured I's holding period with
     respect to the Insured II assets transferred will include the period for
     which such assets were held by Insured II; (ix) the payment of cash to
     Insured II stockholders in lieu of fractional shares of Insured I will be
     treated as though the fractional shares were distributed as part of the
     Reorganization and then redeemed by Insured I, with the result that each
     Insured II stockholder will have short- or long-term capital gain or loss
     to the extent that the cash distribution differs from such stockholder's
     basis allocable to the Insured I fractional shares; and (x) the taxable
     year of Insured II will end on the effective date of the Reorganization and
     pursuant to Section 381(a) of the Code and regulations thereunder, Insured
     I will succeed to and take into account certain tax attributes of Insured
     II, such as earnings and profits, capital loss carryovers and method of
     accounting.
 
          (h) That Insured I shall have received from Ernst & Young 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 Insured I, to the effect that (i) they are
     independent public accountants with respect to Insured II 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 Insured II 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 Insured
     I and Insured II 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 Insured II included in the N-14 Registration
     Statement, and inquiries of certain officials of Insured II 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 Insured I and Insured II
     and described in such letter (but not an examination in accordance with
     generally accepted auditing standards), the information relating to Insured
     II appearing in the N-14 Registration Statement, which information is
     expressed in dollars (or percentages derived from such dollars) concerning
     Insured II (with the exception of performance comparisons, if any), has
     been obtained from the accounting records of Insured II or from schedules
     prepared by officials of Insured II having responsibility for financial and
     reporting matters and such information is in agreement with such records,
     schedules or computations made therefrom.
 
          (i) That the Investments to be transferred to Insured I shall not
     include any assets or liabilities which Insured I, by reason of charter
     limitations or otherwise, may not properly acquire or assume.
 
          (j) 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 Insured II, contemplated by
     the Commission.
 
                                      I-15
<PAGE>   167
 
          (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 Insured II or would
     prohibit the Reorganization.
 
          (l) That Insured I shall have received from the Commission such orders
     or interpretations as Brown & Wood LLP, as counsel to Insured I, 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.
 
          (m) That all proceedings taken by Insured II and its counsel in
     connection with the Reorganization and all documents incidental thereto
     shall be satisfactory in form and substance to Insured I.
 
          (n) That prior to the Exchange Date, Insured II shall declare a
     dividend or dividends which, together with all such previous dividends,
     shall have the effect of distributing to its stockholders all of its net
     investment company taxable income for the period from November 1, 1995 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,
     realized for the period from November 1, 1995 to and including the Exchange
     Date. In this regard, the last dividend period for the Insured II Series A
     AMPS and the Insured II Series B AMPS prior to the Exchange Date may be
     shorter than the dividend period for such AMPS determined as set forth in
     the applicable Articles Supplementary.

     administrative or other proceeding shall be instituted or threatened which
     would materially affect the financial condition of Insured I or would
     prohibit the Reorganization.
 
          (k) That Insured II shall have received from the Commission such
     orders or interpretations as Brown & Wood LLP, as counsel to Insured II,
     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.
 
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 Insured
I and Insured II) prior to the Exchange Date, or the Exchange Date may be
postponed, (i) by mutual consent of the Boards of Directors of Insured I and
Insured II; (ii) by the Board of Directors of Insured I if any condition of
Insured I's obligations set forth in Section 8 of this Agreement has not been
fulfilled or waived by such Board; or (iii) by the Board of Directors of Insured
II if any condition of Insured II's obligations set forth in Section 9 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 June 30, 1997, this Agreement automatically shall terminate on
that date, unless a later date is mutually agreed to by the Boards of Directors
of Insured I and Insured II.
 
     (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 Insured I or Insured II
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 Insured I or
Insured II, 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 Boards of Directors of Insured I and
Insured II have delegated to Fund Asset Management, L.P. the ability to make
non-material changes to the transaction if it deems it to be in the best
interests of Insured I and Insured II 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 Insured I nor Insured II 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 Insured I or Insured II 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.
 
                                      I-18
<PAGE>   170
 
     (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 Insured
I and Insured II 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 Insured I and Insured II, unless such terms and conditions shall result in a
change in the method of computing the number of shares of Insured I Common
Stock, Insured I Series F AMPS and Insured I Series G AMPS to be issued to
Insured II in which event, unless such terms and conditions shall have been
included in the proxy solicitation materials furnished to the stockholders of
Insured I and Insured II prior to the meetings at which the Reorganization shall
have been approved, this Agreement shall not be consummated and shall terminate
unless Insured I and Insured II promptly shall call special meetings of
stockholders at which such conditions so imposed shall be submitted for
approval.
 
11. OTHER MATTERS.
 
     (a) Pursuant to Rule 145 under the 1933 Act, and in connection with the

                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 some time in the future.
 
     Baa -- Bonds which are rated Baa are considered as medium grade
obligations, i.e., they are neither highly protected nor poorly secured.
Interest payments and principal security appear adequate for the present, but
certain protective elements may be lacking or may be characteristically
unreliable over any great length of time. Such bonds lack outstanding investment
characteristics and in fact have speculative characteristics as well.
 
     Ba -- Bonds which are rated Ba are judged to have speculative elements;
their future cannot be considered as well assured. Often the protection of
interest and principal payments may be very moderate and thereby not well
safeguarded during both good and bad times over the future. Uncertainty of
position characterizes bonds in this class.
 
     B -- Bonds which are rated B generally lack characteristics of a desirable
investment. Assurance of interest and principal payments or of maintenance of
other terms of the contract over any long period of time may be small.
 
     Caa -- Bonds which are rated Caa are of poor standing. Such issues may be
in default or there may be present elements of danger with respect to principal
or interest.
 
     Ca -- Bonds which are rated Ca represent obligations which are speculative
in a high degree. Such issues are often in default or have other marked
shortcomings.
 
     C -- Bonds which are rated C are the lowest rated class of bonds and issues
so rated can be regarded as having extremely poor prospects of ever attaining
any real investment standing.
 
     Con. (  ) -- Bonds for which the security depends upon the completion of
some act or the fulfillment of some condition are rated conditionally. These are
bonds secured by (a) earnings of projects under construction, (b) earnings of
projects unseasoned in operation experience, (c) rentals which begin when
 
                                      II-1
<PAGE>   173
 
facilities are completed, or (d) payments to which some other limiting condition
attaches. Parenthetical rating denotes probable credit stature upon completion
of construction or elimination of basis of condition.
 
     Note: Those bonds in the Aa, A, Baa, Ba and B groups which Moody's believes
possess the strongest investment attributes are designated by the symbols Aa1,
A1, Baa1, Ba1 and B1.
 
     Short-term Notes and Variable Rate Demand Obligations: The four ratings of
Moody's for short-term notes and VRDOs are MIG-1/VMIG-1, MIG-2/VMIG-2,
MIG-3/VMIG-3, and MIG-4/VMIG-4; MIG-1/VMIG-1 denotes "best quality, enjoying
strong protection from established cash flows"; MIG-2/VMIG-2 denotes "high
quality" with "ample margins of protection"; MIG-3/VMIG-3 instruments are of
"favorable quality but lacking the undeniable strength of the preceding grades";
MIG-4/VMIG-4 instruments 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 earnings coverage of fixed
financial charges and high internal cash generation; and with established access
to a range of financial markets and assured sources of alternate liquidity.
 
     Issuers rated Prime-2 (or related supporting institutions) have a strong
capacity for repayment of short-term promissory obligations. This will normally
be evidenced by many of the characteristics cited above but to a lesser degree.
Earnings trends and coverage ratios, while sound, will be more subject to
variation. Capitalization characteristics, while still appropriate, may be more
affected by external conditions. Ample alternate liquidity is maintained.
 
     Issuers rated Prime-3 (or related supporting institutions) have an
acceptable capacity for repayment of short-term promissory obligations. The
effects of industry characteristics and market composition may be more
pronounced. Variability in earnings and profitability may result in changes in
the level of debt protection measurements and the requirement for relatively
high financial leverage. Adequate alternate liquidity is maintained.
 
     Issuers rated Not Prime do not fall within any of the Prime rating
categories.
 
DESCRIPTION OF STANDARD & POOR'S RATINGS GROUP'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.
 
                                      II-2
<PAGE>   174
 
     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 to, and relative position of, the obligation
     in the event of bankruptcy, reorganization or other arrangement under the
     laws of bankruptcy and other laws affecting 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.
 
          BB, B, CCC, CC, C -- Debt rated "BB", "B", "CCC", "CC" and "C" is
     regarded, on balance, as predominately speculative with respect to capacity
     to pay interest and repay principal in accordance with the terms of the
     obligation. "BB" indicates the lowest 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 issues. However, it faces major ongoing uncertainties or
     exposure to adverse business, financial, or 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
     currently has the capacity to meet interest payments and principal
     repayments. Adverse business, financial, or economic conditions will
 
                                      II-3
<PAGE>   175
 
     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 currently identifiable vulnerability to
     default, and is dependent upon favorable business, financial and economic
     conditions to meet timely payment of interest and repayment 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 that 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.
 
          C1 -- The rating "C1" is reserved for income bonds on which no
     interest is being paid.
 
          D -- Debt rated "D" is in payment default. The "D" rating category is
     used when interest payments or principal payments are not made on the date
     due even if the applicable grace period has not expired, unless Standard &
     Poor's believes that such payments will be made during such grace period.
     The "D" rating also will be used upon the filing of a bankruptcy petition
     if debt service payments are jeopardized.
 
Plus (+) or Minus (-): The ratings from "AA" to "CCC" may be modified by the
addition of a plus or minus sign to show relative standing within the major
rating categories.
 
DESCRIPTION OF STANDARD & POOR'S COMMERCIAL PAPER RATINGS
 
     A Standard & Poor's commercial paper rating is a current assessment of the
likelihood of timely payment of debt having an original maturity of no more than
365 days. Ratings are graded into several categories, ranging from "A-1" for the
highest quality obligations to "D" for the lowest. The three designations in the
"A" category are as follows:
 
          A-1 -- This highest category indicates that the degree of safety
     regarding timely payment is strong. Those issues determined to possess
     extremely strong safety characteristics are denoted with a "+" designation.
 
          A-2 -- Capacity for timely payment on issues with this designation is
     satisfactory. However, the relative degree of safety is not as high as for
     issues designated "A-1".
 
          A-3 -- Issues carrying this designation have adequate capacity for
     timely payment. They are, however, more vulnerable to the adverse effects
     of changes in circumstances than obligations carrying the higher
     designations.
 
          B -- Issues rated "B" are regarded as having only speculative capacity
     for timely payment.
 
          C -- This rating is assigned to short-term debt obligations with a
     doubtful capacity for payment.
 
                                      II-4
<PAGE>   176
 
          D -- Debt rated "D" is in payment default. The "D" rating category is
     used when interest payments or principal payments are not made on the date
     due, even if the applicable grace period has not expired, unless Standard &
     Poor's believes that such payments will be made during such grace period.
 
     A commercial paper rating is not a recommendation to purchase or sell a
security. The ratings are based on current information furnished to Standard &
Poor's by the issuer or obtained from other sources it considers reliable. The
ratings may be changed, suspended, or withdrawn as a result of changes in, or
unavailability of, such information.
 
     A Standard & Poor's municipal note rating reflects the liquidity concerns
and market access risks unique to such notes. Notes due in three years or less
will likely receive a note rating. Notes maturing beyond three years will most
likely receive a long-term debt rating. The following criteria will be used in
making that assessment.
 
     Amortization schedule (the larger the final maturity relative to other
maturities, the more likely it will be treated as a note).
 
     Source of payment (the more dependent the issue is on the market for its
refinancing, the more likely it will be treated as a note).
 
     Note rating symbols are as follows:
 
        SP-1 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.
 
DESCRIPTION OF FITCH INVESTORS SERVICE, INC.'S ("FITCH") INVESTMENT GRADE BOND
RATINGS
 
     Fitch investment grade bond ratings provide a guide to investors in
determining the credit risk associated with a particular security. The rating
represents Fitch's assessment of the issuer's ability to meet the obligations of
a specific debt issue or class of debt in a timely manner.
 
     The rating takes into consideration special features of the issue, its
relationship to other obligations of the issuer, the current and prospective
financial condition and operating performance of the issuer and any guarantor,
as well as the economic and political environment that might affect the issuer's
future financial strength and credit quality.
 
     Fitch ratings do not reflect any credit enhancement that may be provided by
insurance policies or financial guarantees unless otherwise indicated.
 
     Bonds that have the same rating are of similar but not necessarily
identical credit quality since the rating categories do not fully reflect small
differences in the degrees of credit risk.
 
     Fitch ratings are not recommendations to buy, sell, or hold any security.
Ratings do not comment on the adequacy of market price, the suitability of any
security for a particular investor, or the tax-exempt nature or taxability of
payments made in respect of any security.
 
                                      II-5
<PAGE>   177
 
     Fitch ratings are based on information obtained from issuers, other
obligors, underwriters, their experts, and other sources Fitch believes to be
reliable. Fitch does not audit or verify the truth or accuracy of such
information. Ratings may be changed, suspended, or withdrawn as a result of
changes in, or the unavailability of, information or for other reasons.
 
          AAA -- Bonds considered to be investment grade and of the highest
     credit quality. The obligor has an exceptionally strong ability to pay
     interest and repay principal, which is unlikely to be affected by
     reasonably foreseeable events.
 
          AA -- Bonds considered to be investment grade and of very high credit
     quality. The obligor's ability to pay interest and repay principal is very
     strong, although not quite as strong as bonds rated "AAA". Because bonds
     rated in the "AAA" and "AA" categories are not significantly vulnerable to
     foreseeable future developments, short-term debt of these issuers is
     generally rated "F-1+".
 
          A -- Bonds considered to be investment grade and of high credit
     quality. The obligor's ability to pay interest and repay principal is
     considered to be strong, but may be more vulnerable to adverse changes in
     economic conditions and circumstances than bonds with higher ratings.
 
          BBB -- Bonds considered to be investment grade and of satisfactory
     credit quality. The obligor's ability to pay interest and repay principal
     is considered to be adequate. Adverse changes in economic conditions and
     circumstances, however, are more likely to have adverse impact on these
     bonds, and therefore impair timely payment. The likelihood that the ratings
     of these bonds will fall below investment grade is higher than for bonds
     with higher ratings.
 
Plus (+) or Minus (-): Plus and minus signs are used with a rating symbol to
indicate the relative position of a credit within the rating category. Plus and
minus signs, however, are not used in the "AAA" category.
 
     Credit Trend Indicator: Credit trend indicators show whether credit
fundamentals are improving, stable, declining, or uncertain, as follows:
 
<TABLE>
            <S>           <C>
            Improving     [UP ARROW]
            Stable        [LEFT AND RIGHT ARROW]
            Declining     [DOWN ARROW]
            Uncertain     [UP AND DOWN ARROW]

</TABLE>
 
     Credit trend indicators are not predictions that any rating change will
occur, and have a longer-term time frame than issues placed on FitchAlert.
 
     NR indicates that Fitch does not rate the specific issue.
 
     Conditional: A conditional rating is premised on the successful completion
of a project or the occurrence of a specific event.
 
     Suspended: A rating is suspended when Fitch deems the amount of information
available from the issuer to be inadequate for rating purposes.
 
     Withdrawn: A rating will be withdrawn when an issue matures or is called or
refinanced and, at Fitch's discretion, when an issuer fails to furnish proper
and timely information.
 
                                      II-6

<PAGE>   178
 
     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

DESCRIPTION OF FITCH'S SPECULATIVE GRADE BOND RATINGS
 
     Fitch speculative grade bond ratings provide a guide to investors in
determining the credit risk associated with a particular security. The ratings
("BB" to "C") represent Fitch's assessment of the likelihood of timely payment
of principal and interest in accordance with the terms of obligation for bond
issues not in default. For defaulted bonds, the rating ("DDD" to "D") is an
assessment of the ultimate recovery value through reorganization or liquidation.
 
     The rating takes into consideration special features of the issue, its
relationship to other obligations of the issuer, the current and prospective
financial condition and operating performance of the issuer and any guarantor,
as well as the economic and political environment that might affect the issuer's
future financial strength.
 
     Bonds that have the same rating are of similar but not necessarily
identical credit quality since rating categories cannot fully reflect the
differences in degrees of credit risk.
 
          BB -- Bonds are considered speculative. The obligor's ability to pay
     interest and repay principal may be affected over time by adverse economic
     changes. However, business and financial alternatives can be identified
     which could assist the obligor in satisfying its debt service requirements.
 
          B -- Bonds are considered highly speculative. While bonds in this
     class are currently meeting debt service requirements, the probability of
     continued timely payment of principal and interest reflects the obligor's
     limited margin of safety and the need for reasonable business and economic
     activity throughout the life of the issue.
 
          CCC -- Bonds have certain identifiable characteristics which, if not
     remedied, may lead to default. The ability to meet obligations requires an
     advantageous business and economic environment.
 
          CC -- Bonds are minimally protected. Default in payment of interest
     and/or principal seems probable over time.
 
          C -- Bonds are in imminent default in payment of interest or
     principal.
 
     DDD, DD, and D -- Bonds are in default on interest and/or principal
payments. Such bonds are extremely speculative and should be valued on the basis
of their ultimate recovery value in liquidation or reorganization of the
obligor. "DDD" represents the highest potential for recovery on these bonds, and
"D" represents the lowest potential for recovery.
 
Plus (+) or Minus (-): Plus and minus signs are used with a rating symbol to
indicate the relative position of a credit within the rating category. Plus and
minus signs, however, are not used in the "DDD," "DD," or "D" categories.

DESCRIPTION OF FITCH'S INVESTMENT GRADE 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.
 
     The short-term rating places greater emphasis than a long-term rating on
the existence of liquidity necessary to meet the issuer's obligations in a
timely manner.
 
     Fitch short-term ratings are as follows:
 
<TABLE>
        <S>     <C>
        F-1+    Exceptionally Strong Credit Quality. Issues assigned this rating are
                regarded as having the strongest degree of assurance for timely payment.
        F-1     Very Strong Credit Quality. Issues assigned this rating reflect an
                assurance of timely payment only slightly less in degree than issues rated
                "F-1+".
        F-2     Good Credit Quality. Issues assigned this rating have a satisfactory
                degree of assurance for timely payment, but the margin of safety is not as
                great as for issues assigned "F-1+" and "F-1" ratings.
        F-3     Fair Credit Quality. Issues assigned this rating have characteristics
                suggesting that the degree of assurance for timely payment is adequate;
                however, near-term adverse changes could cause these securities to be
                rated below investment grade.
        F-4     Weak Credit Quality. Issues assigned this rating have characteristics
                suggesting a minimal degree of assurance for timely payment and are
                vulnerable to near-term adverse changes in financial and economic
                conditions.
        D       Default. Issues assigned this rating are in actual or imminent payment
                default.
        LOC     The symbol "LOC" indicates that the rating is based on a letter of credit
                issued by a commercial bank.

                              PORTFOLIO INSURANCE
 
     Set forth below is further information with respect to the Mutual Fund
Insurance Policies (the "Policies") which each Fund may obtain from several
insurance companies with respect to insured Municipal Bonds held by the Fund.
Each Fund has no obligation to obtain any such Policies and the terms of any
Policies actually obtained may vary significantly from the terms described
below.
 
     In determining eligibility for insurance, insurance companies will apply
their own standards which correspond generally to the standards they normally
use in establishing the insurability of new issues of Municipal Bonds and which
are not necessarily the criteria which would be used in regard to the purchase
of such bonds by the Funds. The Policies do not insure (i) municipal securities
ineligible for insurance and (ii) municipal securities no longer owned by a
Fund.
 
     The Policies do not guarantee the market value of the insured Municipal
Bonds or the value of the shares of the Funds. In addition, if the provider of
an original issuance insurance policy is unable to meet its obligations under
such policy or if the rating assigned to the insurance claims-paying ability of
any such insurer deteriorates, the insurance company will not have any
obligation to insure any issue held by a Fund which is adversely affected by
either of the above described events. In addition to the payment of premiums,
the Policies may require that a Fund notify the insurance company as to all
Municipal Bonds in the Fund's portfolio and permit the insurance company to
audit their records. The insurance premiums will be payable monthly by each Fund
in accordance with a premium schedule to be furnished by the insurance company
at the time the Policies are issued. Premiums are based upon the amounts covered
and the composition of the portfolio.
 
     The insurance companies will have insurance claims-paying ability ratings
of AAA from Standard & Poor's Ratings Group ("S&P"), Aaa from Moody's Investors
Service, Inc. ("Moody's") or AAA from Fitch Investors Service, Inc. ("Fitch").
 
     An S&P insurance claims-paying ability rating is an assessment of an
operating insurance company's financial capacity to meet obligations under an
insurance policy in accordance with the terms. An insurer with an insurance
claims-paying ability rating of AAA has the highest rating assigned by S&P.
Capacity to honor insurance contracts is adjudged by S&P to be extremely strong
and highly likely to remain so over a long period of time. A Moody's insurance
claims-paying ability rating is an opinion of the ability of an insurance
company to repay punctually senior policyholder obligations and claims. An
insurer with an insurance claims-paying ability rating of Aaa is adjudged by
Moody's to be of the best quality. In the opinion of Moody's, the policy
obligations of an insurance company with an insurance claimspaying ability
rating of Aaa carry the smallest degree of credit risk and, while the financial
strength of these companies is likely to change, such changes as can be
visualized are most unlikely to impair the company's fundamentally strong
position. A Fitch insurance claims-paying ability rating provides an assessment
of an insurance company's financial strength and, therefore, its ability to pay
policy and contract claims under the terms indicated. An insurer with an
insurance claims-paying ability rating of AAA has the highest rating assigned by
Fitch. The ability to pay claimsis adjudged by Fitch to be extremely strong for
insurance companies with this highest rating. In the opinion of Fitch,
foreseeable business and economic risk factors should not have any material
adverse impact on the ability of these insurers to pay claims. In Fitch's
opinion, profitability, overall balance sheet strength,
 
                                      III-1
<PAGE>   181
 
capitalization and liquidity are all at very secure levels and are unlikely to
be affected by potential adverse underwriting, investment or cyclical events.
 
     An insurance claims-paying ability rating by S&P, Moody's or Fitch does not
constitute an opinion on any specific contract in that such an opinion can only
be rendered upon the review of the specific insurance contract. Furthermore, an
insurance claims-paying ability rating does not take into account deductibles,
surrender or cancellation penalties or the timeliness of payment; nor does it
address the ability of a company to meet nonpolicy obligations (i.e. debt
contracts.)
 
     The assignment of ratings by S&P, Moody's or Fitch to debt issues that are
fully or partially supported by insurance policies, contracts or guarantees is a
separate process from the determination of claims-paying ability ratings. The
likelihood of a timely flow of funds from the insurer to the trustee for the
bondholders is a key element in the rating determination for such debt issues.

                               OTHER INFORMATION
 
ITEM 15. INDEMNIFICATION.
 
     Section 2-418 of the General Corporation Law of the State of Maryland,
Article VI of the Registrant's Articles of Incorporation, Article VI of the
Registrant's By-Laws and the Registrant's Investment Advisory Agreement with
Fund Asset Management, Inc. (now known as Fund Asset Management, L.P.; the
"Investment Adviser") provide for indemnification.
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933, as amended (the "Securities Act"), may be provided to directors,
officers and controlling persons of each Fund, pursuant to the foregoing
provisions or otherwise, each Fund has been advised that in the opinion of the
Securities and Exchange Commission, such indemnification is against public
policy as expressed in the Securities Act and, therefore, is unenforceable. In
the event that a claim for indemnification against such liabilities (other than
the payment by a Fund of expenses incurred or paid by a director, officer or
controlling person of the Registrant in connection with any 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
Registrant, unless in the opinion of its counsel the matter has been settled by
controlling precedent, will submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.
 
     Reference is made to (i) Section Six of the Purchase Agreement relating to
the Registrant's Common Stock, a form of which previously was filed as an
exhibit to the Common Stock Registration Statement (as defined below), and (ii)
Section Seven of the Purchase Agreement relating to the Registrant's AMPS, a
form of which previously was filed as an exhibit to the AMPS Registration
Statement (as defined below), for provisions relating to the indemnification of
the underwriter.

ITEM 17. UNDERTAKINGS.
 
     (a) The Registrant undertakes to suspend offering of the shares of Common
