     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 California Insured Fund II, Inc.,
a Maryland corporation ("MuniYield California Insured II"), and MuniVest
California Insured Fund, Inc., a Maryland corporation ("MuniVest California
Insured"), for use at Annual Meetings of Stockholders (the "Meetings") called to
approve or disapprove the proposed reorganization whereby (i) MuniYield
California Insured II will acquire all of the assets, and will assume all of the
liabilities, of MuniVest California Insured, in exchange solely for an equal
aggregate value of newly-issued shares of Common Stock, par value $.10 per
share, of MuniYield California Insured II ("MuniYield California Insured II
Common Stock") and shares of a newly-created series of Auction Market Preferred
Stock ("AMPS") of MuniYield California 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) to be designated Series C
("MuniYield California Insured II Series C AMPS") to be issued by MuniYield
California Insured II; and (ii) MuniVest California Insured will be deregistered
and dissolved (collectively, the "Reorganization"). MuniYield California Insured
II and MuniVest California Insured 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

            PROXY STATEMENT AND PROSPECTUS. ANY REPRESENTATION TO
               THE CONTRARY IS A CRIMINAL OFFENSE.
                            ------------------------
 
     This Proxy Statement and Prospectus sets forth concisely the information
about MuniYield California Insured II and MuniVest California Insured that
stockholders of MuniYield California Insured II and MuniVest California Insured
should know before considering the Reorganization and should be retained for
future reference. MuniYield California Insured II and MuniVest California
Insured 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.
 
     MuniYield California Insured II Common Stock and MuniVest California
Insured Common Stock are listed on the New York Stock Exchange (the "NYSE")
under the symbols "MCA" and "MVC", respectively. Subsequent to the
Reorganization, shares of MuniYield California Insured II Common Stock will
continue to be listed on the NYSE under the symbol "MCA". 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.
 
     The address of the principal executive offices of both MuniYield California
Insured II and MuniVest California Insured 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.
<PAGE>   6
 
     This Proxy Statement and Prospectus serves as a prospectus of MuniYield
California Insured II under the Securities Act of 1933, as amended (the
"Securities Act"), in connection with the issuance of MuniYield California
Insured II Common Stock and MuniYield California Insured II Series C AMPS in the
Reorganization.
 
     The aggregate net asset value of the MuniYield California Insured II Common
Stock to be issued to MuniVest California Insured and thereafter distributed to
the holders of shares of Common Stock, par value $.10 per share, of MuniVest
California Insured ("MuniVest California Insured Common Stock") will equal the
aggregate net asset value of the shares of MuniVest California Insured Common
Stock on the date of the Reorganization. Similarly, it is intended that the
aggregate liquidation preference and value of the MuniYield California Insured
II Series C AMPS to be issued to MuniVest California Insured and thereafter
distributed to the holders of shares of AMPS of MuniVest California Insured,
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)
("MuniVest California Insured AMPS"), will equal the aggregate liquidation
preference and value of the MuniVest California Insured AMPS on the date of the
Reorganization. As soon as practicable after the receipt by MuniYield California
Insured II of all of MuniVest California Insured's assets and the assumption by
MuniYield California Insured II of all of MuniVest California Insured's
liabilities, MuniVest California Insured will distribute MuniYield California
Insured II Common Stock and MuniYield California Insured II Series C AMPS to
MuniVest California Insured's stockholders as described under "The
Reorganization". Thereafter, MuniVest California Insured 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 MuniYield California Insured II and MuniVest California Insured are
non-diversified, leveraged, closed-end management investment companies with
virtually identical investment objectives. Both MuniYield California Insured II
and MuniVest California Insured seek to provide stockholders with as high a
level of current income exempt from Federal and California income taxes as is
consistent with their respective investment policies and prudent investment
management. MuniYield California Insured II and MuniVest California Insured 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 and
California income taxes ("California Municipal Bonds"). There can be no
assurance that after the Reorganization the surviving fund will achieve the
investment objective of either MuniYield California Insured II or MuniVest
California Insured.

     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 MuniYield California Insured II or MuniVest California Insured,
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

serve for the ensuing year; and (3) to ratify the selection of Deloitte & Touche
LLP as the independent auditors of MuniYield California Insured II and MuniVest
California Insured, for the respective Fund's current fiscal year ending October
31, 1996.
 
     With respect to proposal 1, approval of the Agreement and Plan of
Reorganization by MuniYield California Insured II will require the affirmative
vote of stockholders representing a majority of the outstanding shares of
MuniYield California Insured II Common Stock and of the AMPS of MuniYield
California Insured II, designated Series A and Series B, 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
"MuniYield California Insured II AMPS"), voting together as a single class, and
a majority of the outstanding shares of MuniYield California Insured II AMPS,
voting separately as a class; and approval by MuniVest California Insured will
require the affirmative vote of stockholders representing a majority of the
outstanding shares of MuniVest California Insured Common Stock and MuniVest
California Insured AMPS, voting together as a single class, and a majority of
the outstanding shares of MuniVest California Insured AMPS, voting separately as
a class.
 
     With respect to proposal 2, holders of shares of MuniYield California

the two Directors of MuniYield California Insured II or MuniVest California
Insured, as the case may be, to be elected by the holders of shares 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 MuniYield California Insured
II AMPS or MuniVest California Insured AMPS, respectively, represented at
 
                                        5

the Meetings and entitled to vote; and (y) election of the remaining Directors
of MuniYield California Insured II or MuniVest California Insured, 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, approval of the ratification of the selection
of Deloitte & Touche LLP as the independent auditors of MuniYield California

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 12,678,633 shares of MuniYield California
Insured II Common Stock, 3,600 shares of MuniYield California Insured II AMPS in
two series, 5,961,365 shares of MuniVest California Insured Common Stock and

MuniVest California Insured at the Record Date.
 
     The Boards of Directors of MuniYield California Insured II and MuniVest
California Insured know of no business other than that discussed in proposals 1,

                               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 MuniVest California Insured by MuniYield California
Insured II and the subsequent distribution of MuniYield California Insured II
Common Stock and MuniYield California Insured II Series C AMPS to the holders of
MuniVest California Insured Common Stock and MuniVest California Insured AMPS,
respectively, and (ii) the subsequent deregistration and dissolution of MuniVest
California Insured.
 
                                        6

     At a meeting of the Board of Directors of MuniYield California Insured II
held on June 21, 1996 and at a meeting of the Board of Directors of MuniVest
California Insured held on May 3, 1996, the Boards of Directors of MuniYield
California Insured II and MuniVest California Insured each unanimously approved
a proposal that MuniYield California Insured II acquire all of the assets, and
assume all of the liabilities, of MuniVest California Insured in exchange solely
for MuniYield California Insured II Common Stock and MuniYield California
Insured II Series C AMPS to be issued to MuniVest California Insured and
thereafter distributed to the stockholders of MuniVest California Insured.
Subject to obtaining the necessary approvals from the MuniYield California
Insured II and MuniVest California Insured stockholders, the Board of Directors
of MuniVest California Insured deemed advisable the deregistration of MuniVest
California Insured under the Investment Company Act and its dissolution under
the laws of the State of Maryland.
 
     Both MuniYield California Insured II and MuniVest California Insured seek
to provide stockholders with as high a level of current income exempt from
Federal and California income taxes as is consistent with their respective
investment policies and prudent investment management. Both MuniYield California
Insured II and MuniVest California Insured seek to achieve their investment
objectives by investing primarily in a portfolio of California Municipal Bonds.
Under normal circumstances, at least 80% of each Fund's total assets will be
invested in California 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.
 
     MuniYield California Insured II and MuniVest California Insured are both
non-diversified, leveraged, closed-end management investment companies
registered under the Investment Company Act. If the MuniYield California Insured
II and MuniVest California Insured stockholders approve the Reorganization,
MuniYield California Insured II Common Stock and MuniYield California Insured II
Series C AMPS will be issued to MuniVest California Insured in exchange for the
assets of MuniVest California Insured. After the Reorganization, MuniVest
California Insured will distribute the MuniYield California Insured II Common
Stock and the MuniYield California Insured II Series C AMPS to its stockholders
and thereafter 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
MuniYield California Insured II and MuniVest California Insured have determined
that the Reorganization will potentially benefit the holders of Common Stock of
both MuniYield California Insured II and MuniVest California Insured.
Specifically, after the Reorganization, MuniVest California Insured stockholders
will remain invested in a closed-end fund that has an investment objective and
policies virtually identical to those of MuniVest California Insured and which
utilizes the same management personnel. In addition, it is anticipated that both
MuniYield California Insured II and MuniVest California Insured 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 MuniYield California Insured II AMPS or MuniVest California Insured 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
MuniYield California Insured II and MuniVest California Insured took into
account the investment objective and policies of both MuniYield California
Insured II and MuniVest California Insured, the expenses incurred by both due to
the Reorganization and on an ongoing basis by the new and existing stockholders
of MuniYield California Insured II and the potential benefits, including
economies of scale, to MuniYield California Insured II and
 
                                        7
<PAGE>   12
 
MuniVest California Insured common and preferred stockholders as a result of the
Reorganization. The Boards of Directors of MuniYield California Insured II and
MuniVest California Insured, including all of the Directors who are not
"interested persons", as defined in the Investment Company Act, of MuniYield
California Insured II or MuniVest California Insured, have determined that the
Reorganization is in the best interests of each of the Funds and of the common
and preferred stockholders of MuniYield California Insured II and MuniVest
California Insured and that the interests of such stockholders will not be
diluted as a result of effecting the Reorganization.
 
     If all of the requisite approvals are obtained, it is anticipated that the
Reorganization will occur as soon as practicable after such approval, provided
that the Funds have obtained prior to that time a favorable private letter
ruling from the Internal Revenue Service ("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 MuniYield California Insured II or MuniVest 
California Insured 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 MuniYield California Insured II or MuniVest California
Insured, 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 MuniYield
California Insured II and MuniVest California Insured; (ii) by the Board of
Directors of MuniYield California Insured II if any condition to MuniYield
California Insured II's obligations has not been fulfilled or waived by such
Board; or (iii) by the Board of Directors of MuniVest California Insured if any
condition to MuniVest California Insured'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
    operating 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 annualized 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 a MuniYield California Insured II or MuniVest
California Insured 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

                                   approximately $81.2 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 0.67%, based on average
                                   net assets of approximately $403.8 million
                                   including AMPS, and 0.98%, based on average
                                   net assets of approximately $273.8 million
                                   excluding AMPS.

                                   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 MuniYield
                                   California Insured II AMPS and MuniVest
                                   California Insured 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
                                   MuniYield California Insured II AMPS or
                                   MuniVest California Insured 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 MuniYield California
                                   Insured II AMPS and the MuniVest California
                                   Insured 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

                                 Portfolio Insurance.  The policies are the same
                                   for each Fund with respect to obtaining
                                   insurance for portfolio securities. Under
                                   normal circumstances, 65% of each Fund's
                                   total assets will be invested in California
                                   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, and at
                                   least 80% of each Fund's total assets will be
                                   invested in California Municipal Bonds and
                                   Municipal Bonds with remaining maturities of
                                   one year or more which are insured under
                                   either (i) an insurance policy purchased by

                                   (ii) an insurance policy obtained by the
                                   issuer thereof or any other party. See
                                   "Comparison of the Funds -- Investment

                                 Portfolio Transactions.  The portfolio
                                   transactions in which MuniYield California
                                   Insured II and MuniVest California Insured
                                   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 MuniYield California Insured II
                                   and MuniVest California Insured, 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 MuniYield
                                   California Insured II Common Stock and
                                   MuniVest California Insured Common Stock are
                                   identical. Similarly, the corresponding
                                   voting rights of the holders of shares of
                                   MuniYield California Insured II AMPS and
                                   MuniVest California Insured 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 MuniYield California
                                   Insured II Common Stock and the holders of
                                   shares of MuniVest California Insured Common
                                   Stock. The plans are identical for the two
                                   Funds. See "Comparison of the Funds --
                                   Automatic Dividend Reinvestment Plan". Other

                                   of annual and semi-annual reports, are the
                                   same for the two Funds.

                                   the Reorganization to the effect that, among
                                   other things, neither MuniYield California
                                   Insured II nor MuniVest California Insured
                                   will recognize gain or loss on the

                                   Reorganization".
 
RISK FACTORS AND SPECIAL CONSIDERATIONS
 
     Since both MuniYield California Insured II and MuniVest California Insured
invest primarily in a portfolio of California 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.

SPECIAL CONSIDERATIONS RELATING TO CALIFORNIA MUNICIPAL BONDS
 
     MuniYield California Insured II and MuniVest California Insured ordinarily
invest substantially all of their total assets in California Municipal Bonds
and, therefore, they are more susceptible to factors adversely affecting issuers
of California Municipal Bonds than is a municipal bond investment company that
is not concentrated in issuers of California Municipal Bonds to this degree.
Economic activity in California, as in many other industrially developed states,
tends to be more cyclical than in some other states and in the nation as a
whole. However, diversification of the State's economy has helped enable the
State to maintain a moderate rate of growth. FAM does not believe that the
current economic conditions in California will have a significant adverse effect
on either Fund's ability to invest prudently in California Municipal Bonds. See
Exhibit II -- "Economic Conditions in California".
 
EFFECTS OF LEVERAGE
 
     Utilization of leverage, through the issuance of AMPS, involves certain
risks to holders of MuniYield California Insured II Common Stock and MuniVest
California Insured 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
 
                                       17
<PAGE>   22
 
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 MuniYield California Insured II and
MuniVest California Insured 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
 
     MuniYield California Insured II and MuniVest California Insured 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 MuniYield
California Insured II Common Stock nor the MuniVest California Insured Common
Stock has been rated by a nationally recognized statistical rating organization.
 
     The Board of Directors of each of MuniYield California Insured II or
MuniVest California Insured, as the case may be, without stockholder approval,
may amend, alter or repeal certain definitions or restrictions
 
                                       18
<PAGE>   23
 
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 MuniYield
California Insured II Common Stock and the MuniVest California Insured Common
Stock generally have traded at prices that represent a discount to net asset
value. Since November 1, 1993, share prices for MuniYield California Insured II
Common Stock have traded at a maximum discount of (15.94%) and share prices for
MuniVest California Insured Common Stock have traded at a maximum discount of
(16.33%). 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 MuniYield California
Insured II and MuniVest California Insured 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 and California income taxes as is consistent with the Fund's investment
policies and prudent investment management.
 
     The investment objective and policies of MuniYield California Insured II
and MuniVest California Insured 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 65% of each Fund's total assets
will be invested in California 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, and at least 80% of each Fund's total assets
will be invested in California Municipal Bonds and 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 and California income taxes. Each Fund seeks to invest
substantially all of its total assets in California Municipal Bonds except at
times when, in the judgment of FAM, California 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.
 
     The investment grade California Municipal Bonds in which each Fund invests
are those California 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
 
                                       23
<PAGE>   28
 
Fitch), while considered "investment grade," may have certain speculative
characteristics. In assessing the quality of California 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 California Municipal Bonds are entitled and the
creditworthiness of the insurance company or other financial institution which
provided such credit enhancement. See Exhibit III -- "Ratings of Municipal Bonds
and Commercial Paper" and Exhibit IV -- "Portfolio Insurance".
 
     In the case of California Municipal Bonds 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 California Municipal Bonds to be equivalent to
AAA or Aaa rated securities, as the case may be, even though such California
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 California Municipal Bonds must also comply
with the standards applied by the insurance carriers in determining eligibility
for portfolio insurance.
 
     MuniYield California Insured II and MuniVest California Insured 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. MuniYield
California Insured II and MuniVest California Insured have been advised by their
counsel that the Fund 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 closed-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.
 
                                       24
<PAGE>   29
 
     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 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
MuniYield California Insured II or MuniVest California Insured 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 $75,000,000 and insurance claims-paying ability ratings of AAA from
S&P and Aaa from Moody's. See Exhibit II 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 California Municipal Bonds purchased by the Fund. A
California 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 California 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 California Municipal
Bonds beneficially owned by a Fund. In the event of a sale of any California
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 California
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
 
                                       25
<PAGE>   30
 
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 .20 of
1% to .25 of 1% of the principal amount of the California Municipal Bonds
covered by such Policies. The estimate is based on the expected composition of
each Fund's portfolio of California Municipal Bonds. Additional information
regarding the Policies is set forth in Exhibit IV to this Proxy Statement and
Prospectus. In instances in which the Fund purchases California 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 California 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 California 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 California 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 California Municipal Bonds will not
receive timely scheduled payments of principal or interest). However, the
insured California Municipal Bonds are subject to market risk (i.e.,
fluctuations in market value as a result of changes in prevailing interest
rates).
 
DESCRIPTION OF CALIFORNIA MUNICIPAL BONDS
 
     California 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 California Municipal Bonds if the interest paid
thereon is exempt from Federal and California income tax, even though such bonds
may be "private activity bonds" as discussed below.
 
     The two principal classifications of California Municipal Bonds are
"general obligation" bonds and "revenue" or "special obligation" bonds. General
obligation bonds are secured by the issuer's pledge of faith,
 
                                       26
<PAGE>   31
 
credit and taxing power for the payment of principal and interest. Revenue or
special obligation bonds are payable only from the revenues derived from a
particular facility or class of facilities or, in some cases, from the proceeds
from a special excise tax or other specific revenue source such as from the user
of the facility being financed. Industrial development bonds are in most cases
revenue bonds and generally do not constitute the pledge of the credit or taxing
power of the issuer of such bonds. The payment of the principal and interest on
such industrial development bonds depends solely on the ability of the user of
the facility financed by the bonds to meet its financial obligations and the
pledge, if any, of real and personal property so financed as security for such
payment. California 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 California 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 California 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 MuniYield California Insured II and MuniVest California Insured 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 MuniVest California Insured, which
borrowings shall be repaid within 60 days and not be extended or renewed).
 
     When-Issued Securities and Delayed Delivery Transactions.  MuniYield
California Insured II and MuniVest California Insured 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
 
                                       27
<PAGE>   32
 
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.  MuniYield California Insured II
and MuniVest California Insured 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 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.  MuniYield California Insured II and MuniVest California
Insured 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
 
                                       28
<PAGE>   33
 
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
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 California 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 California 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
 
                                       29
<PAGE>   34
 
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.
 
     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 California 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 California 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
 
                                       30
<PAGE>   35
 
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 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
 
                                       31
<PAGE>   36
 
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.
 
     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
 
     MuniYield California Insured II and MuniVest California Insured 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 Funds 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 Funds
     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 Funds are authorized to borrow money in excess
 
                                       32
<PAGE>   37
 
     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 Funds 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 Funds 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).
 
          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
 
                                       33
<PAGE>   38
 
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".
 
     For so long as any shares of 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.
 
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 California Municipal Bonds owned by
MuniYield California Insured II as of April 30, 1996, 87% are rated in the
highest grade by Moody's or S&P, 98% are rated in the highest two grades, 99%
are rated in the highest three grades, 100% are rated in the highest four
grades, and 0% are unrated. The comparable percentages for MuniVest California
Insured are 83% in the highest grade, 95% in the highest two grades, 100% in the
highest three grades, 100% in the highest four grades and 0% unrated.
 
     There are small differences in concentration among the categories of
issuers of the California Municipal Bonds held in the portfolios of the Funds.
For MuniYield California Insured II, as of April 30, 1996, the highest
concentration of Municipal Bonds was in the transportation industry, other
revenue bonds and the hospitals/healthcare industry, accounting for 21%, 20%,
and 12% of the Fund's portfolio, respectively, whereas for MuniVest California
Insured, the highest concentration was in other revenue bonds, the water & sewer
utilities industry and lease obligations, accounting for 16%, 15% and 14% of the
Fund's portfolio, respectively.
 
  MuniYield California Insured II
 
     As of April 30, 1996, approximately 89% of the market value of MuniYield
California Insured II's portfolio was invested in long-term municipal
obligations and approximately 11% of the market value of MuniYield California
Insured II's portfolio was invested in short-term municipal obligations. The
following

MuniYield California Insured II'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
MuniYield California Insured II and MuniVest California Insured. 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
 
                                       35
<PAGE>   40
 
generally seeks reasonably competitive commission rates, MuniYield California
Insured II and MuniVest California Insured 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
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.
 
     MuniYield California Insured II and MuniVest California Insured 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 that 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 MuniYield California Insured II
AMPS and the MuniVest California Insured 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 MuniYield California Insured II nor MuniVest California
Insured 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
 
                                       36
<PAGE>   41
 
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 114.78% and 41.67% respectively, for MuniYield California Insured II and
90.41% and 81.53% for MuniVest California Insured.
 
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 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
 
     MuniYield California Insured II and MuniVest California Insured each has
outstanding both Common Stock and AMPS. MuniYield California Insured II Common
Stock and MuniVest California Insured Common Stock both are traded on the NYSE.
The shares of MuniYield California 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 MuniYield California Insured II Common Stock was $14.44 and the
market price per share was $13.875. The shares of MuniVest California Insured
Common Stock commenced trading on the NYSE on April 30, 1993. As of April 30,
1996, the net asset value per share of the MuniVest California Insured Common
Stock was $12.93 and the market price per share was $12.50.
 
     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
 
                                       37
<PAGE>   42
 
powers, restrictions, limitations as to dividends, qualifications, or terms or
conditions of redemption. In connection with each Fund's offering of shares of
AMPS, MuniYield California Insured II reclassified 3,600 shares of unissued
capital stock as AMPS, and MuniVest California Insured reclassified 1,600 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.
 
  Preferred Stock
 
     MuniYield California Insured II AMPS are structured identically to MuniVest
California Insured 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. MuniYield
California Insured II AMPS and MuniVest California Insured 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 MuniYield California Insured II Series A AMPS and every seven days in
the case of MuniYield California Insured II Series B AMPS unless MuniYield
California Insured II elects, subject to certain limitations, to have a special
dividend period. As of the auction held on May 24, 1996, the dividend rate on
the MuniYield California Insured II Series A AMPS was 3.60%; as of the auction
held on May 17, 1996, the dividend rate on the MuniYield California Insured II
Series B AMPS was 3.67%.
 
     Similarly, auctions generally have been held and will be held every seven
days in the case of MuniVest California Insured AMPS unless MuniVest California
Insured elects, subject to certain limitations, to have a special dividend
period. As of the auction held on May 28, 1996, the dividend rate on the
MuniVest California Insured AMPS was 3.25%.
 
     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:
 
          (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 MuniYield
California Insured II and MuniVest California Insured currently consist of six
persons, five of whom are not "interested persons" as defined in the Investment
Company Act, of either Fund. The Directors of each Fund are responsible for the
overall supervision of the operations of MuniYield California Insured II and
MuniVest California Insured, as the case may be, and perform the various duties
imposed on the directors of investment companies by the Investment Company Act
and under applicable Maryland law. MuniYield California Insured II and MuniVest
California Insured have the same officers. For further information regarding the
Directors and officers of each Fund, see "Election of Directors".
 
     Management and Advisory Arrangements.  FAM serves as the investment adviser
for both MuniYield California Insured II and MuniVest California Insured
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 MuniYield California Insured II
and MuniVest California Insured. 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.
 
                                       40
<PAGE>   45
 
     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 MuniYield California Insured II and FAM will continue from
year to year if approved annually (a) by the Board of Directors of MuniYield
California Insured II or by a majority of the outstanding shares of MuniYield
California Insured II Common Stock and MuniYield California Insured II AMPS,
voting together as a single class, and (b) by a majority of the Directors of
MuniYield California Insured II 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 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 MuniYield California Insured II.
 
     Similarly, unless earlier terminated as described below, the investment
advisory agreement between MuniVest California Insured and FAM will continue
from year to year if approved annually (a) by the Board of Directors of MuniVest
California Insured or by a majority of the outstanding shares of MuniVest
California Insured Common Stock and MuniVest California Insured AMPS, voting
together as a single class, and (b) by a majority of the Directors of MuniVest
California Insured 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 MuniVest California Insured.
 
VOTING RIGHTS
 
     Voting rights are identical for the holders of shares of MuniYield
California Insured II Common Stock and the holders of shares of MuniVest
California Insured 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.
 
                                       41
<PAGE>   46
 
     Voting rights of the holders of MuniYield California Insured II AMPS are
identical to voting rights of the holders of MuniVest California Insured 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 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 MuniYield California Insured II and
MuniVest California Insured 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
 
     MuniYield California Insured II's current policy with respect to dividends
and distributions relating to shares of MuniYield California Insured II Common
Stock is identical to MuniVest California Insured's policy with respect to
shares of MuniVest California Insured Common Stock. Each Fund intends to
distribute substantially 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
 
                                       42
<PAGE>   47
 
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, MuniYield California Insured II's current policy with respect to
dividends and distributions relating to shares of MuniYield California Insured
II AMPS is identical to MuniVest California Insured's current policy with
respect to shares of MuniVest California Insured 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 MuniYield California
Insured II AMPS and the MuniVest California Insured 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 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 California Municipal Bonds, are exempt from Federal and California
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 and California 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.
 
                                       43
<PAGE>   48
 
     If MuniYield California Insured II or MuniVest California Insured, as the
case may be, retroactively allocates any net capital gains or other income
subject to regular Federal and California 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
in the case of MuniYield California Insured II or by The Bank of New York in the
case of MuniVest California Insured, 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 in the case of MuniYield
California Insured II or by The Bank of New York in the case of MuniVest
California Insured, 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 or The
Bank of New York, 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.
 
     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.
 
                                       44
<PAGE>   49
 
     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.
 
     There are no brokerage charges with respect to shares issued directly by
MuniYield California Insured II or MuniVest California Insured 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.
 
                                       45
<PAGE>   50
 
     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 MuniYield California
Insured II or MuniVest California Insured, 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 to
AMPS in right of payment upon liquidation, $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 MUNIYIELD CALIFORNIA INSURED II, MUNIVEST CALIFORNIA
INSURED AND THEIR STOCKHOLDERS
 
     The tax consequences associated with investment in shares of MuniYield
California Insured II Common Stock are identical to the tax consequences
associated with investment in shares of MuniVest California Insured Common
Stock. Similarly, the tax consequences associated with investment in shares of
MuniYield California Insured II AMPS are identical to the tax consequences
associated with investment in shares of MuniVest California Insured AMPS.
MuniYield California Insured II and MuniVest California Insured 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. Similar rules apply to the Fund if its income is subject to California
tax. In prior years and in the taxable year of the Reorganization, each Fund has
distributed substantially all of its income. MuniYield California Insured II
intends to continue to distribute substantially all of its income in 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
 
                                       46
<PAGE>   51
 
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.
 
     The portion of exempt-interest dividends paid from interest received by
each Fund from California Municipal Bonds also is exempt from California
personal and corporate income tax. However, exempt-interest dividends paid to a
corporate shareholder subject to the California state franchise tax will not be
exempt from taxation. Stockholders subject to income taxation by states other
than California may realize a lower after-tax rate of return than California
residents since the dividends distributed by a Fund generally are not exempt, to
any significant degree, from income taxation by such other states. Each Fund
informs its stockholders annually as to the portion of the Fund's distributions
which constitutes exempt-interest dividends and the portion which is exempt from
California personal and corporate income taxes.
 
     The IRS, in a revenue ruling, held that certain AMPS would be treated as
stock for Federal income tax purposes. The terms of the MuniYield California
Insured II AMPS and the MuniVest California Insured 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 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
 
                                       47
<PAGE>   52
 
distributions are considered taxable ordinary income for Federal and California
income tax purposes. Distributions, if any, from an excess of net long-term
capital gains over net short-term capital losses 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, and are taxable as
ordinary income for California tax purposes. Distributions by the Fund, whether
from exempt-interest income, ordinary income or capital gains, will not be
eligible for the dividends received deduction allowed to 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.
 
     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
 
                                       48
<PAGE>   53
 
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 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,
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.
 
                                       49
<PAGE>   54
 
     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.
 
     Provided the Fund does not have a tax nexus to California, such as through
the location of the Fund's activities or those of its advisors within the state,
under present California law, the Fund is not subject to California taxation. In
the event of a tax nexus to California, the Fund would be subject to California
taxation.
 
AGREEMENT AND PLAN OF REORGANIZATION
 
GENERAL
 
     Under the Agreement and Plan of Reorganization (attached hereto as Exhibit
I), MuniYield California Insured II will acquire all of the assets, and will
assume all of the liabilities, of MuniVest California Insured, in exchange
solely for an equal aggregate value of MuniYield California Insured II Common
Stock and MuniYield California Insured II Series C AMPS to be issued by
MuniYield California Insured II. Upon receipt by MuniVest California Insured of
such shares, MuniVest California Insured will distribute the shares of MuniYield
California Insured II Common Stock to the holders of MuniVest California Insured
Common Stock and will distribute the shares of MuniYield California Insured II
Series C AMPS to the holders of MuniVest California Insured AMPS, in each case
in exchange for their shares in MuniVest California Insured. Separate Articles
Supplementary to the Articles of Incorporation of MuniYield California Insured
II establishing the powers, rights and preferences of the MuniYield California
Insured II Series C 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"), MuniVest California Insured
will file Articles of Dissolution with the Maryland Department to effect the
formal dissolution.
 
     MuniVest California Insured will distribute the shares of MuniYield
California Insured II Common Stock and MuniYield California Insured II Series C
AMPS received by it pro rata to its holders of record of MuniVest California
Insured Common Stock and MuniVest California Insured AMPS, respectively, in
exchange for such stockholder's shares in MuniVest California Insured. Such
distribution would be accomplished by opening new accounts on the books of
MuniYield California Insured II in the names of the common and preferred
stockholders of MuniVest California Insured and transferring to those
stockholder accounts the MuniYield California Insured II Common Stock and the
MuniYield California Insured II Series C AMPS previously credited on those books
to the account of MuniVest California Insured. Each newly-opened account on the
books of MuniYield California Insured II for the previous holders of MuniVest
California Insured Common Stock would represent the respective pro rata number
of shares of MuniYield California Insured II Common Stock (rounded down, in the
case of fractional shares, to the next largest number of whole shares) due such
holder of MuniVest California Insured Common Stock. No fractional shares of
MuniYield California Insured II Common Stock or MuniYield California Insured II
Series C AMPS will be issued. In lieu thereof, MuniYield California Insured II's
transfer agent, State Street Bank and Trust Company, will aggregate all
fractional shares of MuniYield California Insured II 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 MuniVest California Insured Common
Stock certificates. Similarly, each newly-opened account on the books of
MuniYield California Insured II for the previous holders of MuniVest California
Insured AMPS would
 
                                       50
<PAGE>   55
 
represent the respective pro rata number of shares of MuniYield California
Insured II Series C AMPS due such holder of MuniVest California Insured AMPS.
See "Surrender and Exchange of MuniVest California Insured Stock Certificates"
below for a description of the procedures to be followed by MuniVest California
Insured stockholders to obtain their MuniYield California Insured II Common
Stock (and cash in lieu of fractional shares, if any), and/or MuniYield
California Insured II Series C AMPS.
 
     Accordingly, as a result of the Reorganization, every holder of MuniVest
California Insured Common Stock would own shares of MuniYield California Insured
II 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 MuniVest
California Insured Common Stock immediately prior to the Exchange Date. Since
the MuniYield California Insured II Common Stock would be issued at net asset
value in exchange for the net assets of MuniVest California Insured having a
value equal to the aggregate net asset value of those shares of MuniYield
California Insured II Common Stock, the net asset value per share of MuniYield
California Insured II Common Stock should remain virtually unchanged by the
Reorganization. Similarly, since the MuniYield California Insured II Series C
AMPS would be issued at a liquidation preference and value per share equal to
the liquidation preference and value of the MuniVest California Insured AMPS,
the respective liquidation preference per share of the MuniYield California
Insured II Series C AMPS will remain unchanged by the Reorganization. Thus, the
Reorganization will result in no dilution of net asset value of the MuniYield
California Insured II Common Stock, other than to reflect the costs of the
Reorganization, and will result in no dilution of liquidation preference of the
MuniYield California Insured II Series C 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 MuniYield California Insured II
and MuniVest California Insured held on June 21, 1996 and May 3, 1996,
respectively, the Boards of Directors of MuniYield California Insured II and
MuniVest California Insured, respectively, including all of the Directors who
are not "interested persons", as defined in the Investment Company Act, of
MuniYield California Insured II and MuniVest California Insured 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 21, 1996, the Board of Directors of MuniYield California
Insured II approved the filing of Articles Supplementary to MuniYield California
Insured II's Articles of Incorporation establishing the powers, rights and
preferences of the MuniYield California Insured II Series C AMPS in order that
they may be distributed to holders of MuniVest California Insured AMPS as part
of the Reorganization.
 
     As a result of such Board approvals, MuniYield California Insured II and
MuniVest California Insured jointly filed a proxy statement with the Commission
soliciting a vote of the stockholders of MuniYield California Insured II and
MuniVest California Insured to approve the Reorganization. The costs of such
solicitation are to be paid by MuniYield California Insured II after the
Reorganization so as to be borne equally and exclusively on a per share basis by
the holders of MuniYield California Insured II Common Stock and MuniVest
California Insured Common Stock. It is anticipated that annual meetings of
stockholders of MuniYield California Insured II and MuniVest California Insured
will be held on September 9, 1996. If the stockholders of both MuniYield
California Insured II and MuniVest California Insured approve the
 
                                       51
<PAGE>   56
 
Reorganization, the Reorganization will take place as soon as practicable after
such approval, provided that the Funds have obtained prior to that time 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 MUNIYIELD CALIFORNIA INSURED II AND MUNIVEST
CALIFORNIA INSURED 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 MuniYield
California Insured II and MuniVest California Insured 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
MuniYield California Insured II Common Stock and the MuniVest California Insured
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 MuniYield
California Insured II Common Stock or the MuniVest California Insured 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 California 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. California 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 MuniYield
California Insured II and MuniVest California Insured 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 MuniYield California Insured II Common Stock and MuniYield
California Insured II Series C AMPS.  On the Exchange Date, MuniYield California
Insured II will issue to MuniVest California Insured a number of shares of
MuniYield California Insured II Common Stock the aggregate net asset value of
which will equal the aggregate net asset value of shares of MuniVest California
Insured Common Stock on the Valuation Date. Each holder of MuniVest California
Insured Common Stock will receive the number of
 
                                       52
<PAGE>   57
 
shares of MuniYield California Insured II Common Stock corresponding to his or
her proportionate interest in the aggregate net asset value of the MuniVest
California Insured Common Stock.
 
     On the Exchange Date, MuniYield California Insured II also will issue to
MuniVest California Insured a number of shares of MuniYield California Insured
II Series C AMPS the aggregate liquidation preference and value of which will
equal the aggregate liquidation preference and value of MuniVest California
Insured AMPS on the Valuation Date. Each holder of MuniVest California Insured
AMPS will receive the number of shares of MuniYield California Insured II Series
C AMPS corresponding to his or her proportionate interest in the aggregate
liquidation preference and value of the MuniVest California Insured AMPS. No
sales charge or fee of any kind will be charged to MuniVest California Insured
stockholders in connection with their receipt of MuniYield California Insured II
Common Stock or MuniYield California Insured II Series C AMPS in the
Reorganization. It is anticipated that the MuniYield California Insured II
Series C AMPS will follow a similar auction schedule and procedures as those
presently followed by the MuniVest California Insured AMPS. As a result of the
Reorganization, the last dividend period for the MuniVest California Insured
AMPS prior to the Exchange Date may be shorter than the dividend period for such
AMPS determined as set forth in the Articles Supplementary.
 
     Expenses.  MuniYield California Insured II 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 thereof, 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 MuniYield California Insured
II Common Stock and MuniVest California Insured Common Stock. Neither MuniYield
California Insured II nor MuniVest California Insured shall pay any expenses of
its respective stockholders arising out of or in connection with the
Reorganization.
 
     Required Approvals.  Under MuniYield California Insured II's Articles of
Incorporation (as amended to date and including Articles Supplementary
establishing the powers, rights and preferences of the MuniYield California
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
MuniYield California Insured II Common Stock and MuniYield California Insured II
AMPS, voting together as a single class, and of the MuniYield California Insured
II AMPS, voting separately as a class. Similarly, under MuniVest California
Insured's Articles of Incorporation (as amended to date and including Articles
Supplementary establishing the powers, rights and preferences of the MuniVest
California Insured 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 MuniVest California Insured Common Stock and MuniVest California
Insured AMPS, voting together as a single class, and of the MuniVest California
Insured AMPS, voting separately as a class.
 
                                       53
<PAGE>   58
 
     Deregistration and Dissolution.  Following the transfer of the assets and
liabilities of MuniVest California Insured to MuniYield California Insured II
and the distribution of shares of MuniYield California Insured II Common Stock
and MuniYield California Insured II Series C AMPS to MuniVest California Insured
stockholders, MuniVest California Insured 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 MuniYield California Insured II and MuniVest
California Insured 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 MuniYield California Insured II and MuniVest California
Insured, a favorable IRS ruling being received as to tax matters, an opinion of
counsel being received as to securities matters and the continuing accuracy of
various representations and warranties of MuniYield California Insured II and
MuniVest California Insured 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. The Agreement and Plan of Reorganization may be
terminated, and the Reorganization 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 each of MuniYield California Insured II and MuniVest
California Insured) prior to the Exchange Date, or the Exchange Date may be
postponed: (i) by mutual consent of the Boards of Directors of MuniYield
California Insured II and MuniVest California Insured; (ii) by the Board of
Directors of MuniYield California Insured II if any condition of MuniYield
California 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; or (iii)
by the Board of Directors of MuniVest California Insured if any condition of
MuniVest California Insured's obligations set forth in Section 8 of the
Agreement and Plan of Reorganization has not been fulfilled or waived by such
Board.
 
POTENTIAL BENEFITS TO MUNIYIELD CALIFORNIA INSURED II COMMON STOCKHOLDERS AND
MUNIVEST CALIFORNIA INSURED 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 MuniVest California
Insured, following the Reorganization MuniVest California Insured stockholders
will remain invested in a closed-end fund that has investment objectives and
policies similar to that of MuniVest California Insured. 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 California 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 California 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).
 
                                       54
<PAGE>   59
 
     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, registration 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 MuniYield California
Insured II was 0.69%, based on average net assets of approximately $282.6
million including AMPS, and 1.02%, based on average net assets of approximately
$192.6 million excluding AMPS, and the total annualized operating expense ratio
for MuniVest California Insured was 0.81%, based on average net assets of
approximately $121.2 million including AMPS, and 1.21%, based on average net
assets of approximately $81.2 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 0.67%, based on average net
assets of approximately $403.8 million including AMPS, and 0.98%, based on
average net assets of approximately $273.8 million excluding AMPS.
 
     Management projections estimate that MuniYield California Insured II will
have net assets in excess of $387.9 million upon completion of the
Reorganization. A larger asset base should provide benefits in portfolio
management. After the Reorganization, MuniYield California Insured II 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 MuniYield California Insured II AMPS or MuniVest California
Insured 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 MUNIVEST CALIFORNIA INSURED STOCK CERTIFICATES
 
     After the Exchange Date, each holder of an outstanding certificate or
certificates formerly representing shares of MuniVest California Insured Common
Stock or MuniVest California Insured AMPS, as the case may be, will be entitled

may be, a letter of transmittal for use in surrendering his or her certificates
for certificates representing shares of MuniYield California Insured II Common
Stock and MuniYield California Insured II Series C 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, MUNIVEST CALIFORNIA INSURED COMMON AND
PREFERRED STOCKHOLDERS WILL BE FURNISHED WITH INSTRUCTIONS FOR EXCHANGING THEIR

II STOCK CERTIFICATES AND, IF APPLICABLE, CASH IN LIEU OF FRACTIONAL SHARES.
 
     From and after the Exchange Date, certificates formerly representing shares
of MuniVest California Insured Common Stock or MuniVest California Insured AMPS,
as the case may be, will be deemed for all purposes to evidence ownership of the
number of full shares of MuniYield California Insured II Common Stock or
MuniYield California Insured II Series C AMPS distributable with respect to such
shares of Common Stock or AMPS of MuniVest California Insured in the
Reorganization, provided that, until such MuniVest California Insured stock
certificates have been surrendered, no dividends payable to the holders of
record of MuniYield California Insured II Common Stock or MuniYield California
Insured II Series C AMPS, as the case may be, as of any date subsequent to the
Exchange Date will be paid to the holders of such outstanding MuniVest
California Insured stock certificates. Dividends payable to holders of record of
shares of MuniYield California Insured II Common Stock or MuniYield California
Insured II Series C AMPS, as the case may be, as of any date after the Exchange
Date and prior to the exchange of certificates by any MuniVest California
Insured stockholder will be paid to such stockholder, without interest, at the
time such stockholder surrenders his or her MuniVest California Insured stock
certificates for exchange.
 
     From and after the Exchange Date, there will be no transfers on the stock
transfer books of MuniVest California Insured. If, after the Exchange Date,
certificates representing shares of MuniVest California Insured Common Stock or
MuniVest California Insured AMPS are presented to MuniYield California Insured
II, they will be cancelled and exchanged for certificates representing MuniYield
California Insured II Common Stock or MuniYield California Insured II Series C
AMPS, as the case may be, and cash in lieu of fractional shares, if any,
distributable with respect to such MuniVest California Insured Common Stock or
MuniVest California Insured 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. MuniYield California Insured II and MuniVest
California Insured each has elected and qualified for the special tax treatment
afforded RICs under the Code, and MuniYield California Insured II intends to
continue to so qualify after the Reorganization. MuniYield California Insured II
and MuniVest California Insured 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 MuniYield California Insured II and MuniVest
California Insured will each be deemed a "party" to a Reorganization
 
                                       56
<PAGE>   61
 
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 by MuniVest
California Insured as a result of the Reorganization or on the distribution of
MuniYield California Insured II Common Stock and MuniYield California Insured II
Series C AMPS to MuniVest California Insured stockholders under Section
361(c)(1) of the Code; (iii) under Section 1032 of the Code, no gain or loss
will be recognized by MuniYield California Insured II as a result of the
Reorganization; (iv) in accordance with Section 354(a)(1) of the Code, no gain
or loss will be recognized by the stockholders of MuniVest California Insured on
the receipt of MuniYield California Insured II Common Stock and MuniYield
California Insured II Series C AMPS in exchange for their corresponding MuniVest
California Insured Common Stock and MuniVest California Insured AMPS (except to
the extent that MuniVest California Insured common stockholders receive cash
representing an interest in fractional shares of MuniYield California Insured II
in the Reorganization); (v) in accordance with Section 362(b) of the Code, the
tax basis of the MuniVest California Insured assets in the hands of MuniYield
California Insured II will be the same as the tax basis of such assets in the
hands of MuniVest California Insured 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 MuniYield California Insured II
Common Stock and MuniYield California Insured II Series C AMPS received by the
stockholders of MuniVest California Insured in the Reorganization will be equal,
in the aggregate, to the tax basis of the MuniVest California Insured Common
Stock and the MuniVest California Insured AMPS surrendered in the exchange;
(vii) in accordance with Section 1223 of the Code, a stockholder's holding
period for the MuniYield California Insured II Common Stock and MuniYield
California Insured II Series C AMPS will be determined by including the period
for which such stockholder held the MuniVest California Insured Common Stock or
MuniVest California Insured AMPS exchanged therefor, provided, that such
MuniVest California Insured shares were held as a capital asset; (viii) in
accordance with Section 1223 of the Code, MuniYield California Insured II's
holding period with respect to the MuniVest California Insured assets
transferred will include the period for which such assets were held by MuniVest
California Insured; (ix) the payment of cash to MuniVest California Insured
stockholders in lieu of fractional shares of MuniYield California Insured II
will be treated as though the fractional shares were distributed as part of the
Reorganization and then redeemed, with the result that such MuniVest California
Insured 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
MuniYield California Insured II fractional shares; and (x) the taxable year of
MuniVest California Insured will end on the effective date of the Reorganization
and pursuant to Section 381(a) of the Code and regulations thereunder, MuniYield
California Insured II will succeed to and take into account certain tax
attributes of MuniVest California Insured, 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 MuniYield California Insured II, MuniVest California Insured 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 LLP, the issuance of MuniYield California Insured II
Series C AMPS pursuant to the Reorganization in addition to the already existing
MuniYield California Insured II Series A AMPS and Series B 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 three 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
 
                                       57
<PAGE>   62
 
disallowed the dividends paid deduction for dividends on the AMPS, MuniYield
California Insured II 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, MuniYield California Insured II 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 MuniYield California
Insured II and MuniVest California Insured have elected and qualified for
taxation as RICs under Sections 851-855 of the Code, and after the
Reorganization MuniYield California Insured II intends to continue to so
qualify.

                               ELECTION OF DIRECTORS
 
     At the Meetings, the Boards of Directors for MuniYield California Insured
II and MuniVest California Insured 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 MuniYield California Insured II and
MuniVest California Insured approve the Reorganization, then the Board of
Directors of MuniYield California Insured II elected at the Meetings will serve
as the Board of the combined fund, until its next Annual Meeting of Stockholders
and until their successors are elected and qualified. If the stockholders of
either MuniYield California Insured II or MuniVest California Insured 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 that Fund and until their successors are elected and qualified.
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 MuniYield California Insured II
stockholders:
 
          (1) All proxies of the holders of shares of MuniYield California
     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 MuniYield California Insured II AMPS; and
 
          (2) All proxies of the holders of shares of MuniYield California
     Insured II Common Stock and MuniYield California 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 MuniYield
     California Insured II Common Stock and MuniYield California Insured II
     AMPS.
 
     With respect to the proxies of MuniVest California Insured stockholders:
 
          (1) All proxies of the holders of shares of MuniVest California
     Insured 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 MuniVest California Insured AMPS; and
 
          (2) All proxies of the holders of shares of MuniVest California
     Insured Common Stock and MuniVest California Insured 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 MuniVest California
     Insured Common Stock and MuniVest California Insured AMPS.
 
     The Boards of Directors of MuniYield California Insured II and MuniVest

(1) Each of the nominees is a director, trustee or member of an advisory board
    of certain other investment companies for which FAM or MLAM acts as
    investment adviser. See "Compensation of Directors" below.
 
(2) Member of the Audit Committee of the Board of Directors.
 
(3) Interested person, as defined in the Investment Company Act, of the Fund.
 
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
MuniYield California Insured II and MuniVest California Insured 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),
 
                                       65
<PAGE>   70
 
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 MuniYield California Insured II and
MuniVest California Insured, pays all compensation of all officers of each Fund
and all Directors of each Fund who are affiliated with ML & Co. or its
subsidiaries. MuniYield California 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 compensates members of its Audit
Committee, which consists of all of the non-interested Directors. These fees and
expenses for the fiscal year ended October 31, 1995 aggregated $23,667 for
MuniYield California Insured II.
 
     MuniVest California Insured 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 compensates members of its Audit Committee, which
consists of all of the non-interested Directors. These fees and expenses for the
fiscal year ended October 31, 1995 aggregated $22,690 for MuniVest California
Insured.
 
     The following table sets forth compensation paid by MuniYield California
Insured II to the non-interested Directors for the fiscal year ended October 31,
1995, 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-interested Directors.

                       SELECTION OF INDEPENDENT AUDITORS
 
     The Boards of Directors of MuniYield California Insured II and MuniVest
California Insured, including a majority of the Directors who are not
"interested persons", as defined in the Investment Company Act, of the Fund,
have selected the firm of Deloitte & Touche LLP as independent auditors, to
audit the financial statements of the Funds for the current fiscal year ending
October 31, 1996.
 
     The Funds know of no direct or indirect financial interest of such firm in
the Funds. Such appointment is subject to ratification or rejection by the
stockholders of the Funds. If the stockholders of both MuniYield California
Insured II and MuniVest California Insured approve the Reorganization, then the
independent auditors selected at the Meetings for MuniYield California Insured
II will serve as the independent auditors of the combined Fund. If the
stockholders of either MuniYield California Insured II or MuniVest California
Insured 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 the Funds. The Boards of Directors of MuniYield
California Insured II and MuniVest California Insured 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 MuniYield California Insured II and
MuniVest California Insured.
 
     Representatives of Deloitte & Touche LLP 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 11:30 A.M., New York time (for
MuniYield California Insured II) and 11:15 A.M., New York time (for MuniVest
California Insured).
 
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 MuniYield California Insured II or
MuniVest California Insured, 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 returned to the
respective Fund, 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 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 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 MuniYield California Insured II Common
Stock, MuniYield California Insured II AMPS, MuniVest California Insured Common
Stock and MuniVest California Insured 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 12,678,633 shares of
MuniYield California Insured II Common Stock, 3,600 shares of MuniYield
California Insured II AMPS, 5,961,365 shares of MuniVest California Insured
Common Stock and 1,800 shares of MuniVest California Insured AMPS issued and
outstanding and entitled to vote.
 
SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT
OF MUNIYIELD CALIFORNIA INSURED II AND MUNIVEST CALIFORNIA INSURED
 
     To the knowledge of MuniYield California Insured II and MuniVest California
Insured, at the date hereof, no person or entity owns beneficially 5% or more of
the shares of any of the MuniYield California Insured II Common Stock, the
MuniYield California Insured II AMPS, the MuniVest California Insured Common
Stock or the MuniVest California Insured AMPS.
 
     On the Record Date, the Directors and officers of MuniYield California
Insured II as a group (10 persons) owned an aggregate of less than 1% of the
outstanding shares of MuniYield California Insured II Common Stock and MuniYield
California Insured II AMPS.
 
                                       69
<PAGE>   74
 
     On the Record Date, the Directors and officers of MuniVest California
Insured as a group (10 persons) owned an aggregate of less than 1% of the
outstanding shares of MuniVest California Insured Common Stock and MuniVest
California Insured 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
MuniYield California Insured II Common Stock, MuniYield California Insured II
AMPS, MuniVest California Insured Common Stock and MuniVest California Insured
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 MuniYield California Insured II Common
Stock and MuniYield California Insured II AMPS, voting together as a single
class, and of the MuniYield California Insured II AMPS, voting separately as a
class, as well as the affirmative vote of stockholders representing a majority
of the outstanding shares of MuniVest California Insured Common Stock and
MuniVest California Insured AMPS, voting together as a single class, and of the
MuniVest California Insured AMPS, voting separately as a class.
 
     Under Maryland law, stockholders of a registered investment company whose
shares are traded publicly on a national securities exchange, such as MuniVest
California Insured, are not entitled to demand the fair value of their shares
upon a transfer of assets; therefore, the MuniVest California Insured common
stockholders will be bound by the terms of the Reorganization. However, any
common stockholder of MuniVest California Insured may sell his or her shares of
Common Stock at any time on the NYSE. Conversely, since the MuniVest California
Insured AMPS are not traded publicly on a national securities exchange,
stockholders of MuniVest California Insured AMPS will be entitled to appraisal
rights upon the consummation of the Reorganization. As stockholders of the
corporation acquiring the assets of MuniVest California Insured, neither holders
of MuniYield California Insured II Common Stock nor holders of MuniYield
California Insured II 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 MuniYield
California Insured II AMPS are entitled to elect two Directors of MuniYield

shares of MuniVest California Insured AMPS are entitled to elect two Directors
of MuniVest California Insured and holders of shares of MuniVest California
Insured Common Stock and MuniVest California Insured AMPS, voting together as a
single class, are entitled to elect the remaining Directors of MuniVest

Directors of MuniYield California II or MuniVest California Insured, as the case
may be, to be elected by the holders of shares of MuniYield California Insured
II AMPS or MuniVest California Insured AMPS, respectively, voting separately as
a class, will require the affirmative vote of a majority of the votes cast by
holders of that Fund's AMPS, represented at the Meetings and entitled to vote;
and (y) election of the remaining Directors of MuniYield California Insured II
or MuniVest California Insured, as the case may be, will require the affirmative
vote of a majority of the votes cast by 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 MuniYield California Insured II and MuniVest
California Insured will require the affirmative vote of a majority of the votes
cast by holders of each Fund's Common Stock and 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 MuniYield California Insured II, the surviving fund after the
Reorganization, so as to be borne equally and exclusively on a per share basis
by the holders of MuniYield California Insured II Common Stock and MuniVest
California Insured Common Stock.
 
     MuniYield California Insured II and MuniVest California Insured likewise
will reimburse banks, brokers and others for their reasonable expenses in
forwarding proxy solicitation materials to the beneficial owners of shares of
MuniYield California Insured II and MuniVest California Insured and certain
persons that MuniYield California Insured II or MuniVest California Insured may
employ for their reasonable expenses in assisting in the solicitation of proxies
from such beneficial owners of shares of capital stock of MuniYield California
Insured II or MuniVest California Insured.
 
     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 MuniYield California
Insured II. 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 as independent
auditors for each Fund for the current fiscal year (proposal 3) 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
 
                                       71
<PAGE>   76
 
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 and 3 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 and 3; however, abstentions and broker
non-votes will have the same effect as a vote against proposal 1.

INDEPENDENT AUDITORS' REPORT
 
The Board of Directors and Shareholders of
MuniYield California Insured Fund II, Inc.:
 
We have audited the accompanying statement of assets, liabilities and capital,
including the schedule of investments of MuniYield California Insured Fund II,
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 for the period October 30, 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. 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 California
Insured Fund II, 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.

MUNIYIELD CALIFORNIA INSURED FUND II, INC.                OCTOBER 31, 1995

NOTES TO FINANCIAL STATEMENTS

1. SIGNIFICANT ACCOUNTING POLICIES:
MuniYield California 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 MCA. 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.

o 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.

o 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 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.

(g) Reclassification--Generally accepted accounting principles
require that certain differences between accumulated net realized
capital losses for financial reporting and tax purposes, if
permanent, be reclassified to undistributed net investment income.
Accordingly, current year's permanent book/tax differences of $230
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.

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 12,678,633. At October 31, 1995, total paid-in
capital amounted to $177,742,454.

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, 3.65% and Series B, 3.40%.

A two-for-one stock split occurred on December 1, 1994. As a result,
as of October 31, 1995, there were 3,600 AMPS shares authorized,
issued and outstanding with a liquidation preference of $25,000 per
share, plus accumulated and unpaid dividends of $181,192.

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 $183,927 as
commissions.


5. CAPITAL LOSS CARRYFORWARD:
At October 31, 1995, the Fund had a net capital loss carryforward of
approximately $2,501,000, all of which expires in 2003. This amount
will be available to offset like amounts of any future taxable
gains.


6. 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 $0.071678 per share, payable on November 29, 1995 to shareholders

MUNIYIELD CALIFORNIA INSURED FUND II, INC.                     APRIL 30, 1996


NOTES TO FINANCIAL STATEMENTS


1. SIGNIFICANT ACCOUNTING POLICIES:
MuniYield California 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 MCA. 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.

o 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.

o 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.

(f) Dividends and distributions--Dividends from net investment
income are declared and paid monthly. Distributions of capital gains

We conducted our audits in accordance with generally accepted auditing

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 MuniVest California

                  MUNIVEST CALIFORNIA INSURED FUND, INC., OCTOBER 31, 1995


NOTES TO FINANCIAL STATEMENTS

1. SIGNIFICANT ACCOUNTING POLICIES:
MuniVest California 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 MVC. 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.

o 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.

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

(e) Deferred organization and offering expenses--Deferred organiza-
tion expenses are amortized on a straight-line basis over a five-year
period beginning with the commencement of operations of the Fund.
Direct expenses relating to the public offering of the Fund's Common
and Preferred Stock were charged to capital at the time of issuance of
the shares.

(f) Dividends and distributions--Dividends from net investment
income are declared and paid monthly. Distributions of capital gains
are recorded on the ex-dividend dates.

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

sidiary of Merrill Lynch & Co., Inc. ("ML & Co."), which is the

appreciated securities and $42,288 related to depreciated securities.

The aggregate cost of investments at October 31, 1995 for Federal
income tax purposes was $112,527,018.

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 5,961,365. At October 31, 1995, total paid-in
capital amounted to $83,561,999.

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 yield in effect at October 31, 1995 was 3.375%.

A two-for-one stock split occurred on December 1, 1994. As a result,
as of October 31, 1995 there were 1,600 AMPS 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 year ended
October 31, 1995, MLPF&S, an affiliate of FAM, earned $88,206 as
commissions.

5. CAPITAL LOSS CARRYFORWARD:
At October 31, 1995, the Fund had a capital loss carryforward of
approximately $8,322,000, of which $6,105,000 expires in 2002 and

like amounts of any future taxable gains.

ordinary income dividend to Common Stock shareholders in the
amount of $.069464 per share, payable on November 29, 1995 to

NOTES TO FINANCIAL STATEMENTS

1. SIGNIFICANT ACCOUNTING POLICIES:
MuniVest California 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 recur-
ring nature. The Fund determines and makes available for publica-
tion 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 MVC. 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.

o 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.

o 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 trans-
actions 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 beginning
with the commencement of operations of the Fund.

(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.

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

                                                ========        ==========


As of April 30, 1996, net unrealized appreciation for Federal income

rities. The aggregate cost of investments at April 30, 1996 for Federal
income tax purposes was $117,311,603.

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 six months ended April 30, 1996, shares issued and outstanding
remained constant at 5,961,365. At April 30, 1996, total paid-in
capital amounted to $83,561,999.

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 yield in effect at April 30, 1996 was 3.79%.

As of April 30, 1996 there were 1,600 AMPS 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 $38,828 as
commissions.

5. CAPITAL LOSS CARRYFORWARD:
At October 31, 1995, the Fund had a net capital loss carryforward of
approximately $8,322,000, of which $6,105,000 expires in 2002 and
$2,217,000 expires in 2003. This amount will be available to offset
like amounts of any future taxable gains.

ordinary income dividend to Common Stock shareholders in the
amount of $0.061836 per share, payable on May 30, 1996 to share-

     THIS AGREEMENT AND PLAN OF REORGANIZATION (the "Agreement") is made as of
the        day of        , 1996, by and between MuniVest California Insured
Fund, Inc., a Maryland corporation ("MuniVest California Insured"), and
MuniYield California Insured Fund II, Inc., a Maryland corporation ("MuniYield
California Insured II").
 
                             PLAN OF REORGANIZATION
 
     The reorganization will comprise (a) the acquisition by MuniYield
California Insured II of all of the assets, and the assumption by MuniYield
California Insured II of all of the liabilities, of MuniVest California Insured
in exchange solely for an equal aggregate value of newly-issued shares of (i)
common stock, par value $.10 per share, of MuniYield California Insured II
("MuniYield California Insured II Common Stock") and (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 C, of MuniYield California Insured II
("MuniYield California Insured II Series C AMPS"), and (b) the subsequent
distribution to MuniVest California Insured stockholders of (x) all of the
MuniYield California Insured II Common Stock received by MuniVest California
Insured in exchange for their shares of common stock, par value $.10 per share,
of MuniVest California Insured ("MuniVest California Insured Common Stock") and
(y) all of the MuniYield California Insured II Series C AMPS received by
MuniVest California Insured 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), of MuniVest California Insured ("MuniVest California Insured
AMPS"), all upon and subject to the terms hereinafter set forth (collectively,
the "Reorganization").
 
     In the course of the Reorganization, MuniYield California Insured II Common
Stock and MuniYield California Insured II Series C AMPS will be distributed to
MuniVest California Insured stockholders as follows: (i) each holder of MuniVest
California Insured Common Stock will be entitled to receive a number of shares
of MuniYield California Insured II Common Stock equal to the aggregate net asset
value of the MuniVest California Insured Common Stock owned by such stockholder
on the Exchange Date (as defined in Section 7(a) of this Agreement); and (ii)
each holder of MuniVest California Insured AMPS will be entitled to receive a
number of shares of MuniYield California Insured II Series C AMPS equal to the
aggregate liquidation preference (and aggregate value) of the MuniVest
California Insured AMPS owned by such stockholder on the Exchange Date. In
consideration therefor, on the Exchange Date MuniYield California Insured II
shall acquire all of the assets of MuniVest California Insured and shall assume
all of MuniVest California Insured'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.
 
     Prior to the Exchange Date, MuniVest California Insured 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
 
                                       I-1

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 MuniVest California Insured 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 MuniYield California Insured II's
Articles of Incorporation establishing the powers, rights and preferences of the
MuniYield California Insured II Series C AMPS will have been filed with the
State Department of Assessments and Taxation of Maryland (the "Maryland
Department") prior to the Exchange Date (as defined in Section 7(a) of this
Agreement).
 
     As promptly as practicable after the liquidation of MuniVest California
Insured pursuant to the Reorganization, MuniVest California Insured shall be
dissolved in accordance with the laws of the State of Maryland, will terminate
its registration under the Investment Company Act of 1940, as amended (the "1940
Act") and will terminate its listing on the New York Stock Exchange.
 
                                   AGREEMENT

4. ISSUANCE AND VALUATION OF MUNIYIELD CALIFORNIA INSURED II COMMON STOCK AND
   MUNIYIELD CALIFORNIA INSURED II SERIES C AMPS IN THE REORGANIZATION.
 
     Full shares of MuniYield California Insured II Common Stock and MuniYield
California Insured II Series C 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 MuniVest California
Insured acquired in the Reorganization determined as hereinafter provided,
reduced by the amount of liabilities of MuniVest California Insured assumed by
MuniYield California Insured II, shall be issued by MuniYield California Insured
II in exchange for such assets of MuniVest California Insured, plus cash in lieu
of fractional shares. The net asset value of MuniVest California Insured and
MuniYield California Insured II shall be determined as of the Valuation Time in
accordance with the procedures described in (i) the prospectus of MuniYield
California Insured II, dated October 23, 1992, relating to the MuniYield
California Insured II Common Stock and (ii) the prospectus of MuniYield
California Insured II, dated November 23, 1992, relating to the MuniYield
California Insured II AMPS, and no formula will be used to adjust the net asset
value so determined of either MuniVest California Insured or MuniYield
California 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 MuniVest California Insured to
be transferred to MuniYield California Insured II shall be determined by
MuniYield California Insured II pursuant to the procedures utilized by MuniYield
California Insured II in valuing its own assets and determining its own
liabilities for purposes of the Reorganization. Such valuation and determination
shall be made by MuniYield California Insured II in cooperation with MuniVest
California Insured and shall be confirmed in writing by MuniYield California
Insured II to MuniVest California Insured. The net asset value per share of the
MuniYield California Insured II Common Stock and the liquidation preference per
share of the MuniYield California Insured II Series C AMPS shall be determined
in accordance with such procedures and MuniYield California Insured II shall
certify the computations involved. MuniYield California Insured II shall issue
to MuniVest California Insured separate certificates or share deposit receipts
for the MuniYield California Insured II Common Stock and the MuniYield
California Insured II Series C AMPS, each registered in the name of MuniVest
California Insured. MuniVest California Insured then shall distribute the
MuniYield California Insured II Common Stock and the MuniYield California
Insured II Series C AMPS to its corresponding stockholders of MuniVest
California Insured Common Stock and MuniVest California Insured AMPS by
redelivering the certificates or share deposit receipts evidencing ownership of
(i) the MuniYield California Insured II Common Stock to State Street Bank and
Trust Company, as the transfer agent and registrar for the MuniYield California
Insured II Common Stock and (ii) the MuniYield California Insured II Series C
AMPS to IBJ Schroder Bank and Trust Company, as the transfer agent and registrar
for the MuniYield California Insured II Series C AMPS. With respect to any
MuniVest California Insured stockholder holding certificates evidencing
ownership of either the MuniVest California Insured Common Stock or the MuniVest
California Insured AMPS as of the Exchange Date, and subject to MuniYield
California Insured II being informed thereof in writing by MuniVest California
Insured, MuniYield California Insured II will not permit such stockholder to
receive new certificates evidencing ownership of the MuniYield California
Insured II Common Stock or MuniYield California Insured II Series C AMPS,
exchange MuniYield California Insured II Common Stock or MuniYield California
Insured II Series C 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 MuniYield California Insured II
Common Stock or MuniYield California Insured II Series C AMPS, in any case,
until notified by MuniVest California Insured or its agent
 
                                       I-9
<PAGE>   140
 
that such stockholder has surrendered his or her outstanding certificates
evidencing ownership of the MuniVest California Insured Common Stock or the
MuniVest California Insured AMPS or, in the event of lost certificates, posted
adequate bond. MuniVest California Insured, at its own expense, will request its
stockholders to surrender their outstanding certificates evidencing ownership of
the MuniVest California Insured Common Stock or the MuniVest California Insured
AMPS, as the case may be, or post adequate bond therefor.
 
     Dividends payable to holders of record of shares of MuniYield California
Insured II Common Stock and MuniYield California Insured II Series C 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 MuniVest California Insured 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 MuniVest California Insured for exchange.
 
     No fractional shares of MuniYield California Insured II Common Stock will
be issued to holders of MuniVest California Insured Common Stock. In lieu
thereof, MuniYield California Insured II's transfer agent, State Street Bank and
Trust Company, will aggregate all fractional shares of MuniYield California
Insured II Common Stock and sell the resulting full shares on the New York Stock
Exchange at the current market price for shares of MuniYield California Insured
II 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 MuniVest California Insured Common Stock
certificates.

          (a) MuniYield California Insured II shall pay, subsequent to the

     arising out of or in connection with the Reorganization.
 
          (b) If for any reason the Reorganization is not consummated, no party

     unsuitable for MuniYield California Insured II to acquire. Moreover,
     MuniYield California Insured II has no plan or intention to sell or
     otherwise dispose of the assets of MuniVest California Insured to be

     returns and reports required to be filed on or before such date shall have

     under state securities or blue sky laws; (vi) the N-14 Registration

     the effectiveness of the N-14 Registration Statement has been issued and no

     effect the Reorganization have been duly authorized by all necessary
     corporate actions on the part of MuniVest California Insured and MuniYield
     California 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 MuniVest California Insured or MuniYield California
     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 MuniVest California
     Insured and MuniYield California Insured II with regard to matters of fact
     and certain certificates and written statements of governmental officials
     with respect to the good standing of MuniVest California Insured and
     MuniYield California Insured II and on the opinion of Wilmer, Cutler &
     Pickering as to matters of Maryland law.
 
          (f) That MuniVest California Insured 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 MuniVest California
     Insured to MuniYield California Insured II in exchange solely for MuniYield
     California Insured II Common Stock and MuniYield California Insured II
     Series C AMPS as provided in this Agreement will constitute a
     reorganization within the meaning of Section 368(a)(1)(C) of the Code, and
     MuniVest California Insured and MuniYield California 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 MuniVest California Insured as a result
     of the Reorganization or on the distribution of MuniYield California

     to MuniVest California Insured stockholders under Section 361(c)(1) of the

     recognized to MuniYield California Insured II as a result of the
     Reorganization; (iv) in accordance with Section 354(a)(1) of the Code, no

     corresponding MuniVest California Insured Common Stock and MuniVest
     California Insured AMPS (except to the extent that MuniVest California
     Insured stockholders receive cash representing an interest in fractional
     shares of MuniYield California Insured II in the Reorganization); (v) in
     accordance with Section 362(b) of the Code, the tax basis of the MuniVest
     California Insured assets in the hands of MuniYield California Insured II
     will be the same as the tax basis of such assets in the hands of MuniVest
     California Insured 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 MuniYield
     California Insured II Common Stock and MuniYield California Insured II

     Common Stock and MuniVest California Insured AMPS surrendered in exchange;
     (vii) in accordance with Section 1223 of the Code, a stockholder's holding
     period for the MuniYield California Insured II Common Stock and MuniYield
     California Insured II Series C AMPS will be determined by including the
     period for which such stockholder held the MuniVest California Insured
     Common Stock and MuniVest California Insured AMPS exchanged therefor,
     provided, that such MuniVest California Insured shares were held as a
     capital asset; (viii) in accordance with Section 1223 of the Code,
     MuniYield California Insured II's holding period with respect to the

     which such assets were held by MuniVest California Insured; (ix) the
     payment of cash to MuniVest California Insured stockholders in lieu of
     fractional shares of MuniYield California Insured II will be treated as
     though the fractional shares were distributed as part of the Reorganization
     and then redeemed by MuniYield California Insured II, with the result that
     each MuniVest California Insured 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 MuniYield California Insured II
     fractional shares; and (x) the taxable year of MuniVest California Insured
     will end on the effective date of the Reorganization and pursuant to
     Section 381(a) of the Code and regulations thereunder, MuniYield California

     MuniVest California Insured, such as earnings and profits, capital loss
     carryovers and method of accounting.
 
          (g) That all proceedings taken by MuniYield California Insured II and

     California Insured.
 
          (h) That the N-14 Registration Statement shall have become effective

     have been instituted or, to the knowledge of MuniYield California Insured
     II, contemplated by the Commission.
 
          (i) That MuniVest California Insured shall have received from Deloitte
     & Touche LLP a letter dated as of the effective date of the N-14
     Registration Statement and a similar letter dated within five days prior to
     the Exchange Date, in form and substance satisfactory to MuniVest
     California Insured, to the effect that (i) they are independent public
     accountants with respect to MuniYield California 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 MuniYield California 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 MuniVest California Insured and MuniYield California Insured II and

     generally accepted auditing standards) consisting of a reading of any
     unaudited interim financial statements and unaudited supplementary
     information of MuniYield California Insured II included in the N-14
     Registration Statement, and inquiries of certain officials of MuniYield
     California Insured II responsible for financial and accounting matters,

     unaudited financial statements and related unaudited supplementary

     applicable accounting requirements of the 1933 Act and the published rules
     and regulations thereunder, (b) such unaudited financial statements are not
     fairly

     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 MuniVest California Insured and MuniYield
     California Insured II and described in such letter (but not an examination
     in accordance with generally accepted auditing standards), the information
     relating to MuniYield California Insured II appearing in the N-14
     Registration Statement, which information is expressed in dollars (or
     percentages derived from such dollars) concerning MuniYield California

     administrative or other proceeding shall be instituted or threatened which
     would materially affect the financial condition of MuniYield California
     Insured II or would prohibit the Reorganization.
 
          (k) That MuniVest California Insured shall have received from the
     Commission such orders or interpretations as Brown & Wood LLP, as counsel
     to MuniVest California Insured, deems reasonably necessary or desirable

     provided, that such counsel shall have requested such orders as promptly as
     practicable, and all such orders shall be in full force and effect.
 
9. MUNIYIELD CALIFORNIA INSURED II CONDITIONS.
 
     The obligations of MuniYield California Insured II hereunder shall be
subject to the following conditions:
 
          (a) That this Agreement shall have been adopted, and the
     Reorganization shall have been approved, by all of the requisite votes set
     forth in Section 8(a) of this Agreement, and that all such certificates as
     set forth in such Section shall have been obtained.
 
          (b) That MuniVest California Insured shall have furnished to MuniYield
     California Insured II a statement of MuniVest California Insured'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 MuniVest California Insured'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 MuniVest California Insured since October 31,
     1995, other than changes in the Investments since that date or changes in
     the market value of the Investments.
 
          (c) That MuniVest California Insured shall have furnished to MuniYield
     California Insured II a certificate signed by MuniVest California Insured'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
 
                                      I-17
<PAGE>   148
 
     representations and warranties of MuniVest California Insured 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 MuniVest California Insured
     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 MuniVest California Insured shall have delivered to MuniYield
     California Insured II a letter from Deloitte & Touche LLP, dated the
     Exchange Date, stating that such firm has performed a limited review of the
     Federal, state and local income tax returns of MuniVest California Insured
     for the period ended October 31, 1995 (which returns originally were
     prepared and filed by MuniVest California Insured), 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 MuniVest California
     Insured 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 MuniVest California Insured ending upon the liquidation of MuniVest
     California Insured, 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 MuniVest California Insured ending upon liquidation or that MuniVest
     California Insured had not qualified as a regulated investment company for
     Federal income tax purposes for the period from November 1, 1995 through
     liquidation of MuniVest California Insured.
 
          (e) That there shall not be any material litigation pending with

          (f) That MuniYield California Insured II shall have received an
     opinion of Brown & Wood LLP, as counsel to both MuniVest California Insured
     and MuniYield California Insured II, in form and substance satisfactory to
     MuniYield California Insured II and dated the Exchange Date, with respect
     to the matters specified in Section 8(e) of this Agreement and such other
     matters as MuniYield California Insured II reasonably may deem necessary or
     desirable.
 
          (g) That MuniYield California Insured II shall have received a private
     letter ruling from the IRS with respect to the matters specified in Section
     8(f) of this Agreement.

     Registration Statement and a similar letter dated within five days prior to

     California Insured II, to the effect that (i) they are independent public
     accountants with respect to MuniVest California Insured 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 MuniVest California Insured included or

     accounting requirements of the 1933 Act and the published rules and
     regulations thereunder; (iii) on the basis of limited procedures agreed
     upon by MuniVest California Insured and MuniYield California Insured II

     nothing came to their attention that caused them to believe that (a) such
     unaudited financial statements and related unaudited supplementary

     contemplated by the Commission.
 
          (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

     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

10. TERMINATION, POSTPONEMENT AND WAIVERS.

     mutual consent of the Boards of Directors of MuniVest California Insured

     Stock and MuniYield California Insured II Series C AMPS to be issued to

                       ECONOMIC CONDITIONS IN CALIFORNIA
 
     The following information is a brief summary of factors affecting the
economy of the State of California and does not purport to be a complete
description of such factors. Other factors will affect issuers. The summary is
based primarily upon one or more publicly available offering statements relating
to debt offerings of State issuers; however, it has not been updated nor will it
be updated during the year. The Funds have not independently verified the
information.
 
ECONOMIC CONDITIONS
 
     The economy of the State of California (sometimes referred to herein as the
"State") is the largest among the 50 states and one of the largest in the world.
This diversified economy has major components in agriculture, manufacturing,
high technology, trade, entertainment, tourism, construction and services. Total
State gross domestic product of about $835 billion in 1994 was larger than all
but six nations in the world.
 
     California's July 1, 1994 population of over 32 million represented over 12
percent of the total United States population. The official 1990 Census
population was 29,760,021 as of the April 1, 1990, which represented an increase
of over 6 million persons, or 26 percent, during the decade of the 1980's. As of
the April 1, 1990 Census, the median age of California's population was 31.5
years, younger than the 1990 U.S. median of 32.9 years.
 
     California's population is concentrated in metropolitan areas. As of the
April 1, 1990 Census, 96 percent resided in the 23 Metropolitan Statistical
Areas in the State. Overall, California's population per square mile was 191 in
1990. As of July 1, 1994, 69 percent of the population of the State was located
in the two consolidated Metropolitan Statistical Areas in California. The
5-county Los Angeles area accounted for 48 percent, with 15.6 million residents.
The 10-county San Francisco Bay Area represented 21 percent, with a population
of 6.7 million.
 
     After suffering through a severe recession, California's economy has been
on a steady recovery since the start of 1994. Employment grew by over 500,000 in
1994 and 1995, and the pre-recession level of total employment is expected to be
matched in 1996. The strongest growth has been in export-related industries,
business services, electronics, entertainment and tourism, all of which have
offset the recession-related losses which were heaviest in aerospace and
defense-related industries (which accounted for two-thirds of the job losses),
finance and insurance. Residential housing construction, with new permits for
under 100,000 annual new units issued in 1994 and 1995, is weaker than in
previous recoveries, but has been growing slowly since 1993.
 
     The State.  In the years following enactment of the Federal Tax Reform Act
of 1986, and conforming changes to the State's tax laws, taxpayer behavior
became much more difficult to predict, and the State experienced a series of
fiscal years in which revenue came in significantly higher or lower than
original estimates. The 1989-90 Fiscal Year ended with revenues below estimates,
so that the State's budget reserve (the Special Fund for Economic Uncertainties
or "SFEU") was fully depleted by June 30, 1990. This date essentially coincided
with the start of the current recession, which severely affected State General
Fund revenues, and increased expenditures above initial budget appropriations
due to greater health and welfare costs. The State's budget problems in recent
years have also been caused by a structural imbalance which has
 
                                      II-1
<PAGE>   154
 
been identified by the current and previous Administrations. The largest General
Fund Program -- K-14 education, health, welfare and corrections -- was
increasing faster than the revenue base, driven by the State's rapid population
growth. These pressures will continue as population trends maintain strong
demand for health and welfare services, as the school-age population continues
to grow, and as the State's corrections program responds to a "Three Strikes"
law enacted in 1994, which requires mandatory life prison terms for certain
third-time felony offenders.
 
     As a result of these factors and others, from the late 1980's until
1992-93, the State had a period of budget imbalance. During this period,
expenditures exceeded revenues in four out of six years, and the State
accumulated and sustained a budget deficit in the SFEU approaching $2.8 billion
at its peak at June 30, 1993. Starting in the 1990-91 Fiscal Year and for each
fiscal year thereafter, each budget required multi-billion dollar actions to
bring projected revenues and expenditures into balance and to close large
"budget gaps" which were identified. Despite budget actions by the Legislature,
the effects of the recession led to large, unanticipated deficits in the budget
reserve, the SFEU, as compared to projected positive balances. By the 1993-94
Fiscal Year, the accumulated deficit was so large that it was impractical to
budget to retire it in one year, so a two-year program was implemented, using
the issuance of revenue anticipation warrants to carry a portion of the deficit
over the end of the fiscal year. When the economy failed to recover sufficiently
in 1993-94, a second two-year plan was implemented in 1994-95.
 
     Another consequence of the accumulated budget deficits, together with other
factors such as disbursement of funds to local school districts "borrowed" from
future fiscal years and hence not shown in the annual budget, was to
significantly reduce the State's cash resources available to pay its ongoing
obligations. The State's cash condition became so serious in late Spring of 1992
that the State Controller was required to issue revenue anticipation warrants
maturing in the following fiscal year in order to pay the State's continuing
obligations. The State was forced to rely increasingly on external debt markets
to meet its cash needs, as a succession of notes and warrants were issued in the
period from June 1992 to July 1994, often needed to pay previously maturing
notes or warrants. These borrowings were used also in part to spread out the
repayment of the accumulated budget deficit over the end of the fiscal year.
 
     The 1994-95 Fiscal Year represented the fourth consecutive year that the
Governor and the Legislature were faced with a very difficult budget environment
to produce a balanced budget. Many program cuts and budgetary adjustments had
already been made in the last three years. The Governor's budget proposal, as
updated in May and June, 1994, recognized that the accumulated deficit could not
be repaid in one year, and proposed a two-year solution.
 
     Pursuant to the Budget Adjustment Law (the "Law"), the State Controller was
required to make a report by November 15, 1994 on whether the projected cash
resources for the General Fund as of June 30, 1995 would decrease more than $430
million from the amount projected by the State in its Official Statement in
July, 1994 for the sale of $4,000,000,000 of revenue anticipation warrants. On
November 15, 1994, the State Controller issued the report on the State's cash
position required by the Law. The report indicated that the cash position of the
General Fund on June 30, 1995 would be $581 million better than was estimated in
the July, 1994 cash flow projections and therefore, no budget adjustment
procedures would be invoked for the 1994-95 Fiscal Year.
 
     On October 15, 1995, when the State Controller, in conjunction with the
Legislative Analyst's Office, reviewed the estimated cash condition of the
General Fund for the 1995-96 Fiscal Year. The State Controller
 
                                      II-2
<PAGE>   155
 
estimated that the General Fund would not have negative internal cash resources
on June 30, 1996 (i.e., external borrowing would be needed to pay all
obligations due). If a cash shortfall had been identified by the State
Controller, the State Legislature would have been required to enact legislation
providing for sufficient General Fund expenditure reductions, revenue increases,
or both.
 
     1995-96 Budget Act.  On January 10, 1995, the Governor presented his
1995-96 Fiscal Year budget proposal (the "Proposed Budget"). Two of the
principal features of the Proposed Budget were a phased 15% cut in personal
income and corporate taxes, and a further expansion of the "realignment" process
to transfer more responsibility and funding sources for certain health and
welfare programs to local governments. Neither of these proposals was approved
by the Legislature. As a result of the improving economy, with resulting
improved revenue and caseload estimates, the State entered the 1995-96 budget
negotiations with the smallest nominal "budget gap" to be closed in many years.
 
     The 1995-96 Budget Act was signed by the Governor on August 3, 1995. The
Budget Act projects General Fund revenues and transfers of $44.1 billion, a 3.5
percent increase from the prior year. Expenditures are budgeted at $43.4
billion, a 4 percent increase. The Department of Finance projects that, after
repaying the last of the carryover budget deficit, there will be a positive
balance of $28 million in the budget reserve, the SFEU, at June 30, 1996. The
Budget Act also projects Special Fund revenues of $12.7 billion and appropriates
Special Fund expenditures of $13.4 billion.
 
     On January 10, 1996, the Governor released his proposed budget for the next
fiscal year (the "Governor's Budget"). The Governor requested total General Fund
appropriations of about $45.2 billion, based on projected revenues and transfers
of about $45.6 billion, which would leave a budget reserve in the SFEU at June
30, 1997 of about $400 million. The Governor renewed a proposal, which had been
rejected by the Legislature in 1995, for a 15 percent phased cut in individual
and corporate tax rates over three years (the budget proposal assumes this will
be enacted, reducing revenues in 1996-97 by about $600 million). There was also
a proposal to restructure trial court funding in a way which would result in a
$300 million decrease in General Fund revenues. The Governor requested
legislation to make permanent a moratorium on cost of living increases for
welfare payments, and suspension of a renters' tax credit, which otherwise would
go back into effect in the 1996-97 Fiscal Year. He further proposed additional
cuts in certain health and welfare programs. The Governor assumed that cuts
previously approved by the Legislature will receive Federal approval, and
Federal welfare reform would allow the State to reduce welfare costs. As of
mid-April, 1996, approximately $1.6 billion in anticipated health and welfare
cuts for 1996-97 had not yet been approved by the Federal government. There is
no indication as to when Federal welfare reform may be enacted. The Governor's
Budget proposes increases in funding for K-12 schools under Proposition 98, for
State higher education systems (with a second year of no student fee increases),
and for corrections. The Governor's Budget projects external cash flow borrowing
of up to $3.2 billion, to mature by June 30, 1997.
 
LOCAL GOVERNMENTS
 
     The primary units of local government in California are the counties,
ranging in population from 1,300 (Alpine) to over 9,000,000 (Los Angeles).
Counties are responsible for the provision of many basic services, including
indigent healthcare, welfare, courts, jails and public safety in unincorporated
areas. There are also about 480 incorporated cities, and thousands of other
special districts formed for education, utility and other services. The fiscal
condition of local governments has been constrained since the enactment of
"Proposition 13" in 1978, which reduced and limited the future growth of
property taxes, and limited the
 
                                      II-3
<PAGE>   156
 
ability of local governments to impose other taxes. Counties, in particular,
have had fewer options to raise revenues than other local government entities,
and have been required to maintain many services.
 
     In the aftermath of Proposition 13, the State provided aid from the General
Fund to make up some of the loss of property tax moneys, including taking over
the principal responsibility for funding local K-12 schools and community
colleges. Under the pressure of the recent recession, the Legislature has
eliminated remnants of this post-Proposition 13 aid to entities other than K-14
education districts, although it has also provided additional funding sources
(such as sales taxes) and reduced mandates for local services. Many counties
continue to be under severe fiscal stress. While such stress has in recent years
most often been experienced by smaller, rural counties, larger urban counties,
such as Los Angeles, have also been affected.
 
ORANGE COUNTY BANKRUPTCY
 
     In December, 1994, Orange County, California ("Orange County"), together
with its pooled investment funds (the "Pools") filed for protection under
Chapter 9 of the Federal Bankruptcy Code, after reports that the Pools had
suffered significant market losses in their investments, causing a liquidity
crisis for the Pools and Orange County. More than 200 other public entities,
most, but not all, of which are located in Orange County, were also depositors
in the Pools. Orange County has reported the Pools' loss at about $1.69 billion,
or about 23 percent of their initial deposits of approximately $7.5 billion.
Many of the entities which deposited moneys in the Pools, including Orange
County, faced interim and/or extended cash flow difficulties because of the
bankruptcy filing and may be required to reduce programs or capital projects.
Orange County has embarked on a fiscal recovery plan based on sharp reductions
in services and personnel, and rescheduling of outstanding short-term debt using
certain new revenues transferred to Orange County from other local governments
pursuant to special legislation enacted in October, 1995. The termination of the
bankruptcy was approved in June, 1996.
 
CONSTITUTIONAL AND STATUTORY LIMITATIONS; RECENT INITIATIVES, PENDING LITIGATION
 
     Constitutional and Statutory Limitations.  Article XIIIA of the California
Constitution (which resulted from the voter-approved Proposition 13 in 1978)
limits the taxing powers of California public agencies. Article XIIIA provides
that the maximum ad valorem tax on real property cannot exceed 1 percent of the
"full cash value" of the property, and effectively prohibits the levying of any
other ad valorem tax on real property for general purposes. However, on May 3,
1986, Proposition 46, an amendment to Article XIIIA, was approved by the voters
of the State of California, creating a new exemption under Article XIIIA
permitting an increase in ad valorem taxes on real property in excess of 1
percent for bonded indebtedness approved by two-thirds of the voters voting on
the proposed indebtedness. "Full cash value" is defined as "the County
Assessor's valuation of real property as shown on the 1975-76 tax bill under
"full cash value" or, thereafter, the appraised value of real property when
purchased, newly constructed, or a change in ownership has occurred after the
1975 assessment." The "full cash value" is subject to annual adjustment to
reflect increases (not to exceed 2 percent) or decreases in the consumer price
index or comparable local data, or to reflect reductions in property value
caused by damage, destruction or other factors.
 
     Article XIIIB of the California Constitution limits the amount of
appropriations of the State and of the local governments to the amount of
appropriations of the entity for the prior year, adjusted for changes in the
cost of living, population and the services that local government has financial
responsibility for providing. To the extent that the revenues of the State
and/or local government exceed its appropriations, the excess
 
                                      II-4
<PAGE>   157
 
revenues must be rebated to the public either directly or through a tax
decrease. Expenditures for voter-approved debt services are not included in the
appropriations limit.
 
     In 1986, California voters approved an initiative statute known as
Proposition 62. This initiative (i) required that any tax for general
governmental purposes imposed by a local governmental entity be approved by a
majority of the electorate of the governmental entity, (ii) required that any
special tax (defined as taxes levied for other than general government purposes)
imposed by a local governmental entity be approved by a two-thirds vote of the
voters within that jurisdiction, (iii) restricted the use of revenues from a
special tax to the purposes or for the service for which the special tax is
imposed, (iv) prohibited the imposition of ad valorem taxes on real property by
local governmental entities except as permitted by Article XIIIA, (v) prohibited
the imposition of transaction taxes and sales taxes on the sale of real property
by local governments, (vi) required that any tax imposed by a local government
on or after August 1, 1985 be ratified by a majority vote of the electorate
within two years of the adoption of the initiative or be terminated by November
15, 1988, (vii) required that, in the event a local government fails to comply
with the provisions of this measure, a reduction in the amount of property tax
revenues allocated to such local government occurs in an amount equal to the
revenues received by such entity attributable to the tax levied in violation of
the initiative, and (vii) permitted those provisions to be amended exclusively
by the voters of the State of California.
 
     On September 28, 1995 the California Supreme Court upheld the
constitutionality of the provision requiring a two-thirds vote in order for a
local government to impose a "special tax." Although the Supreme Court has yet
to rule on the provision requiring a majority vote for a "general tax," it
appears that the Supreme Court is favorably disposed to uphold that portion of
Proposition 62 as well. In that event, a number of taxes currently being
collected (especially by counties and general law cities) would be invalidated.
Prior collection of such taxes may also be subject to claims for refund unless
the Supreme Court chooses to apply its ruling prospectively. The California
Supreme Court has yet to consider the validity of Proposition 62 with regard to
charter cities.
 
     Recent Initiatives.  At the November 9, 1988 general election, California
voters approved an initiative known as Proposition 98. This initiative amends
Article XIIIB to require that (i) the California Legislature establish a prudent
state reserve fund in an amount it shall deem reasonable and necessary and (ii)
revenues in excess of amounts permitted to be spent and which would otherwise be
returned pursuant to Article XIIIB by revision of tax rates or fee schedules be
transferred and allocated (up to a maximum of 40%) to the State School Fund and
be expended solely for purposes of instructional improvement and accountability.
Proposition 98 also amends Article XVI to require that the State of California
provide a minimum level of funding for public schools and community colleges.
Commencing with the 1988-89 Fiscal Year, money to be applied by the State for
the support of school districts and community college districts shall not be
less than the greater of: (i) the amount which, as a percentage of the State
General Fund revenues which may be appropriated pursuant to Article XIIIB,
equals the percentage of such State General Fund revenues appropriated for
school districts and community college districts, respectively, in Fiscal Year
1986-87 or (ii) the amount required to ensure that the total allocations to
school districts and community college districts from the State General Fund
proceeds of taxes appropriated pursuant to Article XIIIB and allocated local
proceeds of taxes shall not be less than the total amount from these sources in
the prior year, adjusted for increases in enrollment and adjusted for changes in
the costs of living pursuant to the provisions of Article XIIIB. The initiative
permits the enactment of legislation, by a two-thirds vote, to suspend the
 
                                      II-5
<PAGE>   158
 
minimum funding requirements for one year. As a result of Proposition 98, funds
that the State might otherwise make available to its political subdivisions may
be allocated instead to satisfy such minimum funding level.
 
     During the recent recession, General Fund revenues for several years were
less than originally projected, so that the original Proposition 98
appropriations turned out to be higher than the minimum percentage provided in
the law. The Legislature responded to these developments by designating the
"extra" Proposition 98 payments in one year as a "loan" from future years'
Proposition 98 entitlements, and also intended that the "extra" payments would
not be included in the Proposition 98 "base" for calculating future years'
entitlement. By implementing these actions, per-pupil funding from Proposition
98 sources stayed almost constant at approximately $4,220 from Fiscal Year
1991-92 to Fiscal Year 1993-94.
 
     In 1992, a lawsuit was filed, called California Teachers' Association v.
Gould, which challenged the validity of these off-budget loans. As part of the
negotiations leading to the 1995-96 Budget Act, an oral agreement was reached to
settle this case. The parties reached a conditional final settlement of the case
in April, 1996. The settlement requires adoption of legislation satisfactory to
the parties to implement its terms, and final approval by the court.
 
     The settlement provides, among other things, that both the State and K-14
schools share in the repayment of prior years' emergency loans to schools. Of
the total $1.76 billion in loans, the State will repay $935 million by
forgiveness of the amount owed, while schools will repay $825 million. The State
share of the repayment will be reflected as expenditures above the current
Proposition 98 base calculation. The schools' share of the repayment will count
as appropriations that count toward satisfying the Proposition 98 guarantee, or
from "below" the current base. Repayments are spread over the eight-year period
of 1994-95 through 2001-02 to mitigate any adverse fiscal impact. Once the
Director of Finance certifies that a settlement has occurred, approximately $377
million in appropriations from the 1995-96 Fiscal Year to schools will be
disbursed in August 1996.
 
     On November 8, 1994, the voters approved Proposition 187, an initiative
statute ("Proposition 187"). Proposition 187 specifically prohibits funding by
the State of social services, health care services and public school education
for the benefit of any person not verified as either a United States citizen or
a person legally admitted to the United States. Among the provisions in
Proposition 187 pertaining to public school education, the measure requires,
commencing January 1, 1995, that every school district in the State verify the
legal status of every child enrolling in the district for the first time. By
January 1, 1996, each school district must also verify the legal status of
children already enrolled in the district and of all parents or guardians of all
students. If the district "reasonably suspects" that a student, parent or
guardian is not legally in the United States, that district must report the
student to the United States Immigration and Naturalization Service and certain
other parties. The measure also prohibits a school district from providing
education to a student it does not verify as either a United States citizen or a
person legally admitted to the United States. The State Legislative Analyst
estimates that verification costs could be in the tens of millions of dollars on
a statewide level (including verification costs incurred by other local
governments), with first-year costs potentially in excess of $100 million.
 
     The reporting requirements may violate the Family Educational Rights and
Privacy Act ("FERPA"), which generally prohibits schools that receive Federal
funds from disclosing information in student records without parental consent.
Compliance with FERPA is a condition of receiving Federal education funds, which
 
                                      II-6
<PAGE>   159
 
total $2.3 billion annually to California school districts. The Secretary of the
United States Department of Education has indicated that the reporting
requirement in Proposition 187 could jeopardize the ability of school districts
to receive these funds.
 
     Opponents of Proposition 187 have filed at least eight lawsuits challenging
the constitutionality and validity of the measure. On November 2, 1995, a United
States District Court judge struck down the central provisions of Proposition
187 by ruling that parts of Proposition 187 conflict with Federal power over
immigration. The ruling concluded that states may not enact their own schemes to
"regulate immigration or devise immigration regulations which run parallel or
purport to supplement Federal immigration law." As a consequence of the ruling,
students may not be denied public education and may not be asked about their
immigration status when enrolling in public schools. Further, the ruling struck
down the requirements of Proposition 187 that teachers and district employees
report information on the immigrant status of students, parents, and guardians.
An appeal has been filed.
 
     Article XIIIA, Article XIIIB and a number of other Propositions were
adopted pursuant to California's constitutional initiative process. From time to
time, other initiative measures could be adopted by California voters. The
adoption of any such initiatives may cause California issuers to receive reduced
revenues, or to increase expenditures, or both.
 
     Pending Litigation.  The State is a party to numerous legal proceedings,
many of which normally occur in governmental operations. Some of the more
significant lawsuits pending against the State are described herein.
 
     The State is a defendant in 12 lawsuits involving the exclusion of small
business stock gains from preference tax and in some cases, also from taxation.
The lead cases are Mervin Morris v. Franchise Tax Board and James Lennane v.
Franchise Tax Board. The majority of the remaining cases had been deferred
pending the outcome of the Morris and Lennane cases. The Supreme Court has ruled
against the State in Lennane but has not yet ruled in Morris. The State has lost
at least $80 million as a result of the Lennane decision.
 
     In Parr v. State of California, a complaint was filed in Federal court
claiming that payment of wages in registered warrants violated the Fair Labor
Standards Act ("FLSA"). The Federal court held that the issuance of registered
warrants does violate the FLSA but subsequently withdrew its order. The parties
have agreed to a settlement which has to be approved by the trial court. If the
State had lost, the maximum amount of damages could have been approximately $500
million.
 
     The State is involved in a lawsuit seeking reimbursement for alleged
state-mandated costs. In Thomas Hayes v. Commission on State Mandates, the State
Director of Finance is appealing a 1984 decision by the State Board of Control.
The Board of Control decided in favor of local school districts' claims for
reimbursement for special education programs for handicapped students; however,
funds have not been appropriated. The amount of potential liability to the
State, if all potentially eligible school districts pursue timely claims, has
been estimated by the Department of Finance at over $1 billion.
 
     In another case, the State is a defendant in Long Beach Unified School
Districts v. State of California. In this case, the school district seeks
reimbursement for voluntary desegregation costs incurred in the implementation
of California Department of Education guidelines. The years of reimbursement are
from Fiscal Year 1977-78 and each fiscal year thereafter to the present. The
district prevailed in a superior court,
 
                                      II-7
<PAGE>   160
 
and the case has been decided by a State appellate court against the State. A
petition for review was denied and the superior court judgment has become final,
but the court retains jurisdiction to oversee payment. The State anticipates
that the unfavorable outcome will affect pending claims by other school
districts, and the total loss could be in excess of $300 million.
 
     A Federal Court of Appeals in the case of Deanna Beno et al. v. Donna
Shalala et al., reversing a trial court ruling in favor of the State, recently
determined that the Secretary of the United States Department of Health and
Human Services violated the Federal Administrative Procedure Act when she
approved California's Assistance Payment Demonstration Project, which in part,
granted California a waiver from complying with requirements for state
participation in the Federal program for medical assistance ("Medicaid"). The
waiver has allowed California to reduce payments under the Aid to Families with
Dependent Children program ("AFDC"), below 1988 payment levels without violating
Medicaid requirements relating to maintenance of AFDC payment levels. California
had relied, in part, on the waiver to reduce state AFDC payments in 1992, 1993
and 1994. The Court of Appeals remanded the case to the trial court with
instructions to remand the Demonstration Project to the Secretary for additional
consideration of objections raised by the plaintiffs. The effect of the court's
decision on California is uncertain at this time.
 
     One of the features of the 1994-95 Budget Act is a 2.3 percent reduction in
AFDC payments. In Welch v. Anderson, on August 19, 1994, the San Francisco
Superior Court issued a preliminary injunction against the California Director
of Social Services to prevent the 2.3 percent AFDC cuts from becoming effective
September 1, 1994. While September cuts were already in process and could not be
halted, the court ordered the cuts to be restored. The preliminary injunction
has been upheld and the case on the merits remains pending.
 
     The State is involved in two lawsuits related to contamination at the
Stringfellow toxic waste site. In one suit, the State is one of approximately
130 defendants in Penny Newman v. J.B. Stringfellow, et al. in which 3,800
plaintiffs are claiming damages of $850 million arising from contamination at
the Stringfellow toxic waste site. The State is a defendant because it chose the
site and approved the deposit of toxic wastes. Seventeen of the 3,800 plaintiffs
have litigated their claims; in half of these cases plaintiffs' verdicts in the
total amount of $159,000 were received and in the remaining cases verdicts were
entered for the State. The other cases have been settled for $13.5 million. In
the separate suit described in United States, People of the State of California
v. J.B. Stringfellow Jr. et al., the State has been found liable by the District
Court on the counterclaim. The amount of liability is still being litigated
although allocation of liability has been determined by the trial court,
including an allocation of liability to the State.
 
     The State is a defendant in a coordinated action involving 3,000 plaintiffs
seeking recovery for damages caused by the Yuba River flood of February 1986.
The appellate court affirmed the trial court finding of liability in inverse
condemnation and awarded damages of $500,000 to 12 sample plaintiffs. Potential
liability to the remaining 300 plaintiffs, from claims filed, ranges from $800
million to $1.5 billion.
 
     The State is involved in a case concerning the default by Triad Healthcare
on a $167 million loan guaranteed by the Cal-Mortgage Loan Insurance Division of
the Office of Statewide Health Planning and Development ("Cal-Mortgage"). Monies
for the loan were raised through the sale of Certificates of Participation and
Cal-Mortgage insured the debt service payments. Since July 1993, Triad has
failed to make its monthly debt service payments; therefore, the reserve account
of the bonds has been used to make the payments. Once the reserve account is
exhausted, additional debt service payments would be made from the

Health Facility Construction Loan Insurance Fund as they become due. However, if
there is any shortfall in this fund, the State's General Fund would be used to
make up the difference.
 
     In Jernigan & Burleson v. State, filed in Federal district court, the
prison inmate plaintiffs claim they are entitled to minimum wages while working
for the Prison Industry Authority. The inmates claim that the State has violated
the FLSA. Plaintiffs are seeking back pay for the period from August 1990
onward, and liquidated damages for a total of approximately $350 million. In
June 1995, the district court ruled that the inmates are not employees under the
FLSA. The decision has been appealed to the Ninth Circuit Court of Appeals.
 
     Additional lawsuits challenge the transfer of moneys from special fund
accounts within the State Treasury to the State's General Fund pursuant to the
Budget Acts of 1991, 1992, 1993 and 1994. Plaintiffs in the two cases titled
Abramovitz et al. v. Wilson et al., filed in State and Federal court seek to
have the transfers reversed and the moneys allegedly totalling approximately
$400 million returned to the special funds. Plaintiffs in the case of Kurt
Hathaway, et al. v. Wilson, filed in State court seek to reverse transfers of
money from special fund accounts to the State's General Fund authorized in the
1994 and 1995 Budget Acts, allegedly totalling approximately $370 million. The
State disputes both liability and the amount claimed. In the case of
Professional Engineers in California Government v. Wilson, several State
employees' unions have challenged transfers made from special funds to the
General Fund pursuant to the Budget Acts of 1993, 1994 and 1995 and seek
reimbursement of over $400 million to these special funds.
 
     In the case of Board of Administration, California Public Employees'
Retirement System, et al. v. Pete Wilson, Governor, et al., plaintiffs
challenged the constitutionality of legislation which deferred payment of the
State's employer contribution to the Public Employees' Retirement System
("PERS") beginning in Fiscal Year 1992-1993. On January 11, 1995, the Sacramento
County Superior Court entered a judgment finding that the legislation
unconstitutionally impaired the vested contract rights of PERS members. The
judgment provides for issuance of a writ of mandate directing State defendants
to disregard the provisions of the legislation, to implement the statute
governing employer contributions that existed before the changes in the
legislation were found to be unconstitutional and to transfer to PERS the
1993-94 and 1994-95 contributions that are unpaid to date. The State defendants
have appealed.

                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 the
desirable investment. Assurance of interest and principal payments or of
maintenance of other terms of the contract over any long period of time may be
small.
 
     Caa -- Bonds which are rated Caa are of poor standing. Such issues may be
in default or there may be present elements of danger with respect to principal
or interest.
 
     Ca -- Bonds which are rated Ca represent obligations which are speculative
in a high degree. Such issues are often in default or have other marked
shortcomings.
 
     C -- Bonds which are rated C are the lowest rated class of bonds and issues
so rated can be regarded as having extremely poor prospects of ever attaining
any real investment standing.
 
     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
 
                                      III-1
<PAGE>   163
 
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.
 
                                      III-2
<PAGE>   164
 
     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
 
                                      III-3
<PAGE>   165
 
        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.
 
                                      III-4
<PAGE>   166
 
          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.
 
                                      III-5
<PAGE>   167
 
     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>             <C>
              Improving       UP ARROW
              Stable          BI-DIRECTIONAL ARROW--LEFT/RIGHT
              Declining       DOWN ARROW
              Uncertain       BI-DIRECTIONAL ARROW--UP/DOWN
</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.
 
                                      III-6
<PAGE>   168
 
FITCHALERT:  Ratings are placed on FitchAlert to notify investors of an
occurrence that is likely to result in a rating change and the likely direction
of such change. These are designated as "Positive" indicating a potential
upgrade, "Negative" for potential downgrade, or "Evolving" where ratings may be
raised or lowered. FitchAlert is relatively short-term, and should be resolved
within three to 12 months.
 
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.
 
                                      III-7
<PAGE>   169
 
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>      <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

                              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 claims-paying 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 claims is 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,
 
                                      IV-1
<PAGE>   171
 
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.

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.
