                                  Common Stock
 
                                  -----------
 
  MuniHoldings Insured Fund III, Inc. (the "Fund") is a newly organized, non-
diversified, closed-end management investment company that seeks to provide
shareholders with current income exempt from Federal income taxes. The Fund
seeks to achieve its objective by investing primarily in a portfolio of long-
term, investment grade municipal obligations the interest on which, in the
opinion of bond counsel to the issuer, is exempt from Federal income taxes. The
Fund intends to invest in municipal obligations that are rated investment grade
or, if unrated, are considered by the Fund's investment adviser to be of
comparable quality. Under normal circumstances, at least 80% of the Fund's
assets will be invested in municipal obligations with remaining maturities of
one year or more that are covered by insurance guaranteeing the timely payment
of principal at maturity and interest.
   
  Because the Fund is newly organized, its shares have no history of public
trading. Shares of closed-end investment companies frequently trade at a
discount from their net asset value. This risk may be greater for investors
expecting to sell their shares in a relatively short period after completion of
the public offering. The Fund plans to apply to list its shares on the New York
Stock Exchange or another national securities exchange under the symbol "MSR."
Trading of the Fund's common stock on the exchange is expected to begin within
two weeks of the date of this prospectus. Before it begins trading, the
underwriter does not intend to make a market in the Fund's shares. Thus,
investors may not be able to buy and sell shares of the Fund during that time.
    
  Within approximately three months after completion of this offering of common
stock, the Fund intends to offer shares of preferred stock representing
approximately 40% of the Fund's capital immediately after the issuance of such
preferred stock. There can be no assurance, however, that preferred stock
representing such percentage of the Fund's capital will actually be issued. The
use of preferred stock to leverage the common stock can create special risks.

                               PROSPECTUS SUMMARY
 
  This summary is qualified in its entirety by reference to the detailed
information included in this prospectus.
 
The Fund    MuniHoldings Insured Fund III, Inc. is a newly organized, non-
            diversified, closed-end management investment company.
 
The            
Offering    The Fund is offering 6,700,000 shares of common stock at an initial
            offering price of $15.00 per share. The common stock is being
            offered by Merrill Lynch, Pierce, Fenner & Smith Incorporated, as
            underwriter. The underwriter may also purchase up to an additional
            1,005,000 shares of common stock within 45 days of the date of this
            prospectus to cover over-allotments.     
 
Investment  The investment objective of the Fund is to provide shareholders
Objective   with current income exempt from Federal income taxes. The Fund
and         seeks to achieve its objective by investing primarily in a
Policies    portfolio of long-term, investment grade municipal obligations the
            interest on which, in the opinion of bond counsel to the issuer, is
            exempt from Federal income taxes.
 
            Investment Grade Municipal Bonds. The Fund intends to invest in
            municipal bonds that are rated investment grade by one or more
            nationally recognized statistical rating agencies or, if unrated,
            are considered by the Fund's investment adviser to be of comparable
            quality.
 
            The Fund will normally invest at least 80% of its assets in insured
            municipal obligations with remaining maturities of one year or
            more. Insured municipal obligations are covered by insurance that
            guarantees timely interest payments and the repayment of principal
            on maturity.
               
            In general, the Fund does not intend its investments to earn a
            large amount of interest income that is not exempt from Federal
            income taxes.     
 
            Indexed and Inverse Floating Rate Securities. The Fund may invest
            in securities whose potential returns are directly related to
            changes in an underlying index or interest rate, known as indexed
            securities. The return on indexed securities will rise when the
            underlying index or interest rate rises and fall when the index or
            interest rate falls. The Fund may also invest in securities whose
            return is inversely related to changes in an interest rate (inverse
            floaters). In general, income on inverse floaters will decrease
            when short term interest rates increase and increase when short
            term interest rates decrease. Investments in inverse floaters may
            subject the Fund to the risks of reduced or eliminated interest
            payments and losses of principal. In addition, certain indexed
            securities and inverse floaters may increase or decrease in value
            at a greater rate than the underlying interest rate, which
            effectively leverages the Fund's investment. As a result, the
            market value of such securities will generally be more volatile
            than that of fixed rate, tax exempt securities. Both indexed
            securities and inverse floaters are derivative securities and can
            be considered speculative.
 
                                       3

            Options and Futures Transactions. The Fund may seek to hedge its
            portfolio against changes in interest rates using options and
            financial futures contracts. The Fund's hedging transactions are
            designed to reduce volatility, but come at some cost. For example,
            the Fund may try to limit its risk of loss from a decline in price
            of a portfolio security by purchasing a put option. However, the
            Fund must pay for the option, and the price of the security may not
            in fact drop. In large part, the success of the Fund's hedging
            activities depends on its ability to forecast movements in
            securities prices and interest rates. The Fund does not, however,
            intend to enter into options and futures transactions for
            speculative purposes. The Fund is not required to hedge its
            portfolio and may not do so.
 
Leverage    Issuance of Preferred Stock. The Fund intends to offer shares of
            preferred stock within three months after completion of this
            offering. The preferred stock will represent approximately 40% of
            the Fund's capital, including the capital raised by issuing the
            preferred stock. There can be no assurance, however, that preferred
            stock will actually be issued. Issuing preferred stock will result
            in the leveraging of the common stock. Although the Board of
            Directors has not yet determined the terms of the preferred stock
            offering, the Fund expects that the preferred stock will pay
            dividends that will be adjusted over either relatively short-term
            periods (generally seven to 28 days) or medium-term periods (up to
            five years). The preferred stock dividend rate will be based upon
            prevailing interest rates for debt obligations of comparable
            maturity. The money raised by the preferred stock offering will be
            invested in longer-term obligations in accordance with the Fund's
            investment objective. The expenses of the preferred stock, which
            will be borne by the Fund, will reduce the net asset value of the
            common stock. In addition, at times, when the Fund is required to
            allocate taxable income to preferred stockholders, the terms of the
            preferred stock may require the Fund to make an additional
            distribution to them. The amount of this additional distribution
            approximately equals the tax liability resulting from the
            allocation (an "Additional Distribution"). During periods when the
            Fund has preferred stock outstanding, the Fund will pay fees to the
            investment adviser for its services that are higher than if the
            Fund did not issue preferred stock because the fees will be
            calculated on the basis of the Fund's average weekly net assets,
            including proceeds from the sale of preferred stock.
 
            Potential Benefits of Leverage. Under normal market conditions,
            longer term obligations produce higher yields than short and medium
            term obligations. The Fund's investment adviser believes that the
            interest income the Fund receives from its long term investments
            will exceed the amount of interest the Fund must pay to the
            preferred stockholders. Thus, the Fund's use of preferred stock
            should provide common stockholders with a higher yield than they
            would receive if the Fund were not leveraged.
 
            Risks. The use of leverage creates certain risks for common
            stockholders, including higher volatility of both the net asset
            value and the market value of the common stock. Since any decline
            in the value of the Fund's investments will affect only the common
            stockholders, in a declining market the use of leverage will cause
            the Fund's net asset value to decrease more than it would if the
            Fund were not leveraged. This decrease in net asset value will
            likely also
 
                                       4

            cause a decline in the market price for shares of common stock. In
            addition, fluctuations in the dividend rates paid on, and the
            amount of taxable income allocable to, the preferred stock will
            affect the yield to common stockholders. There can be no assurance
            that the Fund will earn a higher net return on its investments than
            the then current dividend rate (and any Additional Distribution) it
            pays on the preferred stock. Under certain conditions, the benefits
            of leverage to common stockholders will be reduced, and the Fund's
            leveraged capital structure could result in a lower rate of return
            to common stockholders than if the Fund were not leveraged.
 
            Distributions. When the Fund issues preferred stock, common
            stockholders will receive all of the Fund's net income that remains
            after it pays dividends (and any Additional Distribution) on the
            preferred stock and generally will be entitled to a pro rata share
            of net realized capital gains. If the Fund is liquidated, preferred
            stockholders will be entitled to receive liquidating distributions
            before any distribution is made to common stockholders. These
            liquidating distributions are expected to equal the original
            purchase price per share of the preferred stock plus any
            accumulated and unpaid dividends and Additional Distributions.
 
            Redemption of Preferred Stock. The Fund may redeem the preferred
            stock for any reason. For example, the Fund may redeem all or part
            of the preferred stock if it believes that the Fund's leveraged
            capital structure will cause common stockholders to obtain a lower
            return than they would if the common stock were unleveraged for any
            significant amount of time.
 
            Voting Rights. Preferred stockholders, voting as a separate class,
            will be entitled to elect two of the Fund's Directors. Common and
            preferred stockholders, voting together as a single class, will be
            entitled to elect the remaining Directors. If the Fund fails to pay
            dividends to the preferred stockholders for two full years, the
            holders of all outstanding shares of preferred stock, voting as a
            separate class, would then be entitled to elect a majority of the
            Fund's Directors. The preferred stockholders also will vote
            separately on certain other matters as required under the Fund's
            Articles of Incorporation, the Investment Company Act of 1940, as
            amended, and Maryland law. Otherwise, common and preferred
            stockholders will have equal voting rights (one vote per share) and
            will vote together as a single class.
 
            Ratings. Before it offers the preferred stock, the Fund intends to
            apply to one or more nationally recognized statistical ratings
            organizations for ratings on the preferred stock. The Fund believes
            that a rating for the preferred stock will make it easier to market
            the stock, which should reduce the dividend rate.
 
Listing     Currently, there is no public market for the Fund's common stock.
            However, the Fund plans to apply to list the Fund's common stock on
            the New York Stock Exchange or another national securities
            exchange. Trading of the Fund's common stock is expected to begin
            within two weeks of the date of this prospectus. Before it begins
            trading, the underwriter does not intend to make a market in the
            Fund's shares of common stock. Thus, investors may not be able to
            buy and sell shares of the Fund during that period.

Investment     
Adviser     Fund Asset Management, L.P. is the Fund's investment adviser and
            provides investment advisory and management services to the Fund.
            For its services, the Fund pays the investment adviser a fee at the
            annual rate of 0.55% of the Fund's average weekly net assets,
            including assets acquired from the sale of preferred stock.     
 
Dividends   The Fund intends to distribute dividends equal to substantially all
and Dis-    of its net investment income to common stockholders each month.
tributions  Once the Fund issues preferred stock, the monthly distributions to
            common stockholders will consist of substantially all net
            investment income that remains after the Fund pays dividends (and
            any Additional Distribution) on the preferred stock. The Fund
            expects to begin paying dividends to common stockholders within
            approximately 90 days from the date of this prospectus. The Fund
            will distribute net capital gains, if any, at least annually to
            common stockholders and, after it issues the preferred stock, on a
            pro rata basis to common and preferred stockholders. When the Fund
            allocates capital gains or other taxable income to preferred
            stockholders, under certain circumstances, the terms of the
            preferred stock may require the Fund to make an Additional
            Distribution. The Fund may not declare any cash dividend or other
            distribution on its common stock unless the preferred stock has
            asset coverage of at least 200%. If the Fund issues preferred stock
            representing 40% of its total capital, the preferred stock's asset
            coverage will be approximately 250%. If the Fund's ability to make
            distributions on its common stock is limited, the Fund may not be
            able to qualify for taxation as a regulated investment company.
            This would have adverse tax consequences for stockholders.
 
Automatic   Dividend and capital gains distributions generally are used to
Dividend    purchase additional shares of the Fund's common stock. However, an
Reinvestmentinvestor can choose to receive distributions in cash. Since not all
Plan        investors can participate in the automatic dividend reinvestment
            plan, you should call your broker or nominee to confirm that you
            are eligible to participate in the plan.
 
Mutual      Investors who purchase shares in this offering through the
Fund        underwriter and later sell their shares have the option, subject to
Investment  certain conditions, to purchase Class D shares of certain Merrill
Option      Lynch funds with the proceeds from the sale.

                    RISK FACTORS AND SPECIAL CONSIDERATIONS
 
  Liquidity and Market Price of Shares. The Fund is newly organized and has no
operating history or history of public trading. Before the Fund's common stock
is listed on the New York Stock Exchange or another national securities
exchange, an investment in the Fund may be illiquid.
 
  Shares of closed-end funds that trade in a secondary market frequently trade
at a market price that is below their net asset value. This is commonly
referred to as "trading at a discount." Investors who sell their shares within
a relatively short period after completion of the public offering are more
likely to be exposed to this risk. The Fund is designed primarily for long-term
investors and should not be considered a vehicle for trading purposes.
 
  Non-diversification. The Fund is registered as a "non-diversified" investment
company. This means that the Fund may invest a greater percentage of its assets
in a single issuer than a diversified investment company. Even as a non-
diversified fund, the Fund must still meet the diversification requirements of
applicable Federal income tax laws. Since the Fund may invest a relatively high
percentage of its assets in a limited number of issuers, the Fund may be more
exposed to any single economic, political or regulatory occurrence than a more
widely-diversified fund.
 
  Interest Rate and Credit Risk. The Fund invests in municipal bonds that are
subject to interest rate and credit risk. Interest rate risk is the risk that
prices of municipal bonds generally increase when interest rates decline and
decrease when interest rates increase. Prices of longer term securities
generally change more in response to interest rate changes than prices of
shorter term securities. Credit risk is the risk that the issuer will be unable
to pay the interest or principal when due. The degree of credit risk depends on
both the financial condition of the issuer and the terms of the obligation.
 
  Rating Categories. The Fund intends to invest in municipal bonds that are
rated investment grade by Standard & Poor's, Moody's Investors Service, Inc.
and Fitch IBCA, Inc. It may also invest in unrated municipal bonds that the
Fund's investment adviser believes are of comparable quality. Obligations rated
in the lowest investment grade category may have certain speculative
characteristics.
 
  Private Activity Bonds. The Fund may invest in certain tax-exempt securities
classified as "private activity bonds." These bonds may subject certain
investors in the Fund to the alternative minimum tax.
 
  Portfolio Insurance and Rating Agencies. The Fund will be subject to certain
investment restrictions imposed by guidelines of the insurance companies that
issue portfolio insurance and to guidelines of one or more nationally
recognized statistical ratings organizations that may issue ratings for the
preferred stock. These guidelines may impose asset coverage or portfolio
composition requirements that are more stringent than those imposed by the
Investment Company Act of 1940, as amended. The Fund does not expect these
requirements or guidelines to prevent the investment adviser from managing the
Fund's portfolio in accordance with the Fund's investment objective and
policies.
 
  Leverage. The Fund plans to offer shares of preferred stock. The preferred
stock will represent approximately 40% of the Fund's capital, including capital
raised by issuing the preferred stock. Leverage
 
                                       7
<PAGE>
 
creates certain risks for common stockholders, including higher volatility of
both the net asset value and the market value of the common stock. Leverage
also creates the risk that the investment return on shares of the Fund's common
stock will be reduced to the extent the dividends paid on preferred stock and
other expenses of the preferred stock exceed the income earned by the Fund on
its investments. If the Fund is liquidated, preferred stockholders will be
entitled to receive liquidating distributions before any distribution is made
to common stockholders.
 
  Inverse Floating Obligations. The Fund's investments in "inverse floating
obligations" or "residual interest bonds" provide investment leverage because
their market value increases or decreases in response to market changes at a
greater rate than fixed rate, long term tax exempt securities. The market
values of such securities are more volatile than the market values of fixed
rate, tax exempt securities.
 
  Options and Futures Transactions. The Fund may engage in certain options and
futures transactions to reduce its exposure to interest rate movements. If the
Fund incorrectly forecasts market values, interest rates or other factors, the
Fund's performance could suffer. The Fund also may suffer a loss if the other
party to the transaction fails to meet its obligations. The Fund is not
required to use hedging and may not do so.
 
  Antitakeover Provisions. The Fund's Articles of Incorporation include
provisions that could limit the ability of other entities or persons to acquire
control of the Fund or to change the composition of its Board of Directors.
Such provisions could limit the ability of shareholders to sell their shares at
a premium over prevailing market prices by discouraging a third party from
seeking to obtain control of the Fund.

    40% of the Fund's capital at a dividend rate of 3.375%. The Fund intends to
    use leverage only if the Investment Adviser believes that it would result
    in higher income to shareholders over time. See "Risks and Special
    Considerations of Leverage." If the Fund does not utilize leverage, it is
    estimated that, as a percentage of net assets attributable to common stock,
    the Investment Advisory Fees would be 0.55%, Other Expenses would be 0.12%
    and Total Annual Expenses would be 0.67%.

expenses set forth under "Other Expenses" are based on estimated amounts
through the end of the Fund's first fiscal year. The Example set forth above
assumes reinvestment of all dividends and distributions and uses a 5% annual
rate of return as mandated by the Securities and Exchange Commission
regulations. The Example should not be considered a representation of future
expenses or annual rates of return, and actual expenses or annual rates of
return may be more or less than those assumed for purposes of the Example.

                                    THE FUND
 
  MuniHoldings Insured Fund III, Inc. (the "Fund") is a newly organized, non-
diversified, closed-end management investment company. The Fund was
incorporated under the laws of the State of Maryland on April 5, 1999, and has
registered under the 1940 Act. The Fund's principal office is located at 800
Scudders Mill Road, Plainsboro, New Jersey 08536, and its telephone number is
(609) 282-2800.
 
  The Fund has been organized as a closed-end investment company. Closed-end
investment companies differ from open-end investment companies (commonly
referred to as "mutual funds") in that closed-end investment companies do not
generally make a continuous offering of their shares or redeem their securities
at the option of the shareholder, whereas open-end companies issue securities
redeemable at net asset value at any time at the option of the shareholder and
typically engage in a continuous offering of their shares. Accordingly, open-
end investment companies are subject to continuous asset in-flows and out-flows
that can complicate portfolio management. Shares of closed-end investment
companies, however, frequently trade at a discount from their net asset value.
This risk may be greater for investors expecting to sell their shares in a
relatively short period after completion of the public offering.
 
                                USE OF PROCEEDS
 
  The net proceeds of this offering will be approximately $            (or
approximately $            assuming the Underwriter exercises the over-
allotment option in full) after payment of offering expenses estimated to be
approximately $       .
 
  The net proceeds of the offering will be invested in accordance with the
Fund's investment objective and policies within approximately three months
after completion of the offering of common stock, depending on market
conditions and the availability of appropriate securities. Pending such
investment, it is anticipated that the proceeds will be invested in short-term,
tax-exempt securities. See "Investment Objective and Policies."
 
                       INVESTMENT OBJECTIVE AND POLICIES
 
  The Fund's investment objective is to provide shareholders with current
income exempt from Federal income taxes. The Fund will seek to achieve its
objective by investing primarily in a portfolio of long-term, investment grade
municipal obligations issued by or on behalf of states, territories and
possessions of the United States and their political subdivisions, agencies or
instrumentalities, and other qualifying issuers, each of which pays interest
that, in the opinion of bond counsel to the issuer, is exempt from Federal
income taxes ("Municipal Bonds"). The Fund will maintain at least 80% of its
assets in Municipal Bonds, except during interim periods pending investment of
the net proceeds of public offerings of the Fund's securities and during
temporary defensive periods. Under normal circumstances, at least 80% of the
Fund's assets will be invested in municipal obligations with remaining
maturities of one year or more that are covered by insurance guaranteeing the
timely payment of principal at maturity and interest. The Fund's investment
objective is a fundamental policy that may not be changed without a vote of a
majority of the Fund's outstanding voting securities, as defined below under
"Investment Restrictions." There can be no assurance that the investment
objective of the Fund will be realized. At times the Fund may seek to hedge its
portfolio through the use of options and futures transactions to reduce
volatility in the net asset value of its shares of common stock.
 
                                       10
<PAGE>
 
   
  The Fund ordinarily does not intend to realize significant interest income
that is subject to Federal income taxes. The Fund may invest all or a portion
of its assets 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 Fund also may invest in securities not issued by or on behalf of a state
or territory or by an agency or instrumentality thereof, if the Fund
nevertheless believes such securities pay interest or distributions that are
exempt from Federal income taxation ("Non-Municipal Tax-Exempt Securities").
Non-Municipal Tax-Exempt Securities may include securities issued by other
investment companies that invest in Municipal Bonds, to the extent such
investments are permitted by the Investment Company Act of 1940, as amended
(the "1940 Act"). Other Non-Municipal Tax-Exempt Securities could include trust
certificates or other instruments evidencing interests in one or more long-term
Municipal Bonds. Certain Non-Municipal Tax-Exempt Securities may be
characterized as derivative instruments. Non-Municipal Tax-Exempt Securities
are considered "Municipal Bonds" for purposes of the Fund's investment
objective and policies.
 
  Investment in shares of the Fund's common stock offers several potential
benefits. The Fund offers investors the opportunity to receive income exempt
from Federal income taxes by investing in a professionally managed portfolio
comprised primarily of investment grade insured Municipal Bonds. Investment in
the Fund also relieves the investor of the burdensome administrative details
involved in managing a portfolio of Municipal Bonds. Additionally, the Fund's
investment adviser, Fund Asset Management, L.P. (the "Investment Adviser"),
will seek to enhance the yield on the common stock by leveraging the Fund's
capital structure through the issuance of preferred stock. The benefits are at
least partially offset by the expenses involved in operating an investment
company. Such expenses primarily consist of the advisory fee and operational
costs. Additionally, the use of leverage involves certain expenses and special
risk considerations. See "Risks and Special Considerations of Leverage."
 
  The investment grade Municipal Bonds in which the Fund will primarily invest
are those Municipal Bonds rated at the date of purchase in the four highest
rating categories of Standard & Poor's ("S&P"), Moody's Investors Services,
Inc. ("Moody's") or Fitch IBCA, Inc. ("Fitch"), or, if unrated, considered to
be of comparable quality by the Investment Adviser. In the case of long-term
debt, the investment grade rating categories are AAA through BBB for S&P, Aaa
through Baa 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-3 for Moody's and F-1+ through F-3 for Fitch. In the
case of tax-exempt commercial paper, the investment grade rating categories are
A-1+ through A-3 for S&P, Prime-1 through Prime-3 for Moody's and F-1+ through
F-3 for Fitch. Obligations ranked in the lowest investment grade rating
category (BBB, SP-3 and A-3 for S&P; Baa, MIG-3 and Prime-3 for Moody's; and
BBB and F-3 for Fitch), while considered "investment grade," may have certain
speculative characteristics. There may be sub-categories or gradations
indicating relative standing within the rating categories set forth above. See
Appendix I to this Prospectus for a description of S&P's, Moody's and Fitch's
ratings of Municipal Bonds. In assessing the quality of Municipal Bonds with
respect to the foregoing requirements, the Investment Adviser will take into
account the portfolio insurance as well as the nature of any letters of credit
or similar credit enhancements to which particular Municipal Bonds are entitled
and the creditworthiness of the insurance company or the financial institution
that provided such insurance or credit enhancements. Consequently, if Municipal
Bonds are covered by insurance policies issued by insurers whose claims-paying
ability is rated AAA by S&P or Fitch or Aaa by Moody's, the Investment Adviser
may consider such municipal obligations to be equivalent to AAA- or Aaa- rated
 
                                       11
<PAGE>
 
securities, as the case may be, even though such Municipal Bonds would
generally be assigned a lower rating if the rating were based primarily upon
the credit characteristics of the issuers without regard to the insurance
feature. The insured Municipal Bonds must also comply with the standards
applied by the insurance carriers in determining eligibility for portfolio
insurance.
 
  The Fund's investments may also include variable rate demand obligations
("VRDOs") and VRDOs in the form of participation interests ("Participating
VRDOs") in variable rate tax-exempt obligations held by a financial
institution, typically a commercial bank. The VRDOs in which the Fund will
invest are tax-exempt obligations, in the opinion of counsel to the issuer,
that contain a floating or variable interest rate adjustment formula and an
unconditional right of demand on the part of the holder thereof to receive
payment of the unpaid principal balance plus accrued interest on a short notice
period not to exceed seven days. Participating VRDOs provide the Fund with a
specified undivided interest (up to 100%) in 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. The Fund has been advised by its
counsel that the Fund should be entitled to treat the income received on
Participating VRDOs as interest from tax-exempt obligations.
 
  The average maturity of the Fund's portfolio securities will vary based upon
the Investment Adviser'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 the 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, as proposed for the Fund. See "Risks and
Special Considerations of Leverage."
 
  The Fund intends to invest primarily in long-term Municipal Bonds with a
maturity of more than ten years. Also, the Fund may invest in intermediate-term
Municipal Bonds with a maturity of between three years and ten years. The Fund
may invest in short-term, tax-exempt securities, short-term U.S. Government
securities, repurchase agreements or cash. Such short-term securities or cash
will not exceed 20% of its total assets except during interim periods pending
investment of the net proceeds of public offerings of the Fund's securities or
in anticipation of the repurchase or redemption of the Fund's securities and
temporary periods when, in the opinion of the Investment Adviser, prevailing
market or economic conditions warrant. The Fund does not ordinarily intend to
realize significant interest income that is subject to Federal income taxes.
 
  The Fund is classified as non-diversified within the meaning of the 1940 Act,
which means that the Fund is not limited by the 1940 Act in the proportion of
its assets that it may invest in securities of a single issuer. However, the
Fund's investments will be limited so as to qualify the Fund for special tax
treatment afforded regulated investment companies under the Federal tax laws.
See "Taxes." To qualify, among other requirements, the Fund will limit its
investments so that, at the close of each quarter of the taxable year, (i) not
more than 25% of the market value of the Fund's total assets will be invested
in the securities (other than U.S. Government securities) of a single issuer,
and (ii) with respect to 50% of the market value of its total assets, not more
than 5% of the market value of its total assets will be invested in the
securities (other than U.S. Government securities) of a single issuer. A fund
that elects to be classified as "diversified" under the 1940
 
                                       12
<PAGE>
 
Act must satisfy the foregoing 5% requirement with respect to 75% of its total
assets. To the extent that the Fund assumes large positions in the securities
of a small number of issuers, the Fund's net asset value may fluctuate to a
greater extent than that of a diversified company as a result of changes in the
financial condition or in the market's assessment of the issuers.
 
Portfolio Insurance
 
  Under normal circumstances, at least 80% of the 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 Fund will seek to limit its investments
to municipal bonds insured under insurance policies issued by insurance
carriers that have total admitted assets (unaudited) of at least $75,000,000
and capital and surplus (unaudited) of at least $50,000,000 and insurance
claims-paying ability ratings of AAA from S&P or Fitch or Aaa from Moody's.
There can be no assurance that insurance from insurance carriers meeting these
criteria will be at all times available. See Appendix II to this Prospectus for
a brief description of S&P's, Fitch's and Moody's insurance claims-paying
ability ratings. Currently, it is anticipated that a majority of the insured
Municipal Bonds in the Fund's portfolio will be insured by the following
insurance companies that satisfy the foregoing criteria: AMBAC Indemnity
Corporation, Financial Guaranty Insurance Company, Financial Security Assurance
and Municipal Bond Investors Assurance Corporation. The Fund also may purchase
Municipal Bonds covered by insurance issued by any other insurance company that
satisfies the foregoing criteria. It is anticipated that initially a majority
of insured Municipal Bonds held by the Fund will be insured under policies
obtained by parties other than the Fund.
 
  The Fund may purchase, but has no obligation to purchase, separate insurance
policies (the "Policies") from insurance companies meeting the criteria set
forth above that guarantee the payment of principal and interest on specified
eligible Municipal Bonds purchased by the Fund. A Municipal Bond will be
eligible for coverage if it meets certain requirements of the insurance company
set forth in a Policy. In the event interest or principal on an insured
Municipal Bond is not paid when due, the insurer will be obligated under its
Policy to make such payment not later than 30 days after it has been notified
by, and provided with documentation from, the Fund that such nonpayment has
occurred.
 
  The Policies will be effective only as to insured Municipal Bonds
beneficially owned by the Fund. In the event of a sale of any Municipal Bonds
held by the Fund, the issuer of the relevant Policy will be liable only for
those payments of interest and principal that are then due and owing. The
Policies will not guarantee the market value of the insured Municipal Bonds or
the value of the shares of the Fund.
 
  The insurer will not have the right to withdraw coverage on securities
insured by their Policies and held by the 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 the Fund will reserve 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 the Fund and the yield on the
Fund's portfolio is reduced thereby. The Investment Adviser estimates that the
cost of the annual premiums for the Policies currently ranges from
approximately .02 of 1% to .15 of 1% of the principal amount of the Municipal
Bonds covered by such Policies. The estimate is based on the expected
composition of the Fund's portfolio of Municipal Bonds. Additional information
regarding the Policies is set forth in Appendix II to this Prospectus. In
instances in
 
                                       13
<PAGE>
 
which the Fund purchases Municipal Bonds insured under policies obtained by
parties other than the Fund, the Fund does not pay the premiums for such
policies; rather, the cost of such policies may be reflected in the purchase
price of the Municipal Bonds.
 
  It is the intention of the Investment Adviser to retain any insured
securities that 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 that are not in default. In certain circumstances, however, the
Investment Adviser may determine that an alternate value for the insurance,
such as the difference between the market value of the defaulted security and
its par value, is more appropriate. The Investment Adviser's ability to manage
the portfolio may be limited to the extent it holds defaulted securities, which
may limit its ability in certain circumstances to purchase other Municipal
Bonds. See "Net Asset Value" below for a more complete description of the
Fund's method of valuing defaulted securities and securities that have a
significant risk of default.
 
  There can be no assurance that insurance with the terms and issued by
insurance carriers meeting the criteria described above will continue to be
available to the Fund. In the event the Board of Directors determines that such
insurance is unavailable or that the cost of such insurance outweighs the
benefits to the Fund, the Fund may modify the criteria for insurance carriers
or the terms of the insurance, or may discontinue its policy of maintaining
insurance for all or any of the Municipal Bonds held in the Fund's portfolio.
Although the Investment Adviser periodically reviews the financial condition of
each insurer, there can be no assurance that the insurers will be able to honor
their obligations under all circumstances.
   
  The portfolio insurance reduces financial or credit risk (i.e., the
possibility that the owners of the insured Municipal Bonds will not receive
timely scheduled payments of principal or interest). However, the insured
Municipal Bonds are subject to market risk (i.e., fluctuations in market value
as a result of changes in prevailing interest rates or other market
conditions).     
 
Description of Municipal Bonds
 
  Municipal Bonds include debt obligations issued to obtain funds for various
public purposes, including construction of a wide range of public facilities,
refunding of outstanding obligations and obtaining funds for general operating
expenses and loans to other public institutions and facilities. In addition,
certain types of industrial development bonds ("IDBs") are issued by or on
behalf of public authorities to finance various privately operated facilities,
including certain local facilities for water supply, gas, electricity, sewage
or solid waste disposal. For purposes of this prospectus, such obligations are
Municipal Bonds if the interest paid thereon is exempt from Federal income tax
even though such bonds may be IDBs or "private activity bonds" as discussed
below. Also, for purposes of this prospectus, Non-Municipal Tax-Exempt
securities as discussed above will be considered Municipal Bonds.
   
  The two principal classifications of Municipal Bonds are "general obligation"
bonds and "revenue" bonds, which latter category includes IDBs and, for bonds
issued after August 15, 1986, private activity bonds. General obligation bonds
are typically secured by the issuer's pledge of faith, credit and taxing power
for the repayment of principal and the payment of interest. Revenue or special
obligation bonds typically are payable only from the revenues derived from a
particular facility or class of facilities or, in some cases, from the proceeds
of a special excise tax or other specific revenue source such as from the user
of the facility being financed. IDBs are in most cases revenue bonds and do not
generally constitute the pledge of the credit or taxing power of the issuer of
such bonds. The repayment of principal and the payment of interest on revenue
    
                                       14
<PAGE>
 
   
bonds, including IDBs, depends solely on the ability of the user of the
facility financed by the bonds to meet its financial obligations and the
pledge, if any, of real and personal property so financed as security for such
payment. Municipal Bonds may also include "moral obligation" bonds, which are
normally issued by special purpose public authorities. If an issuer of moral
obligation bonds is unable to meet its obligations, the repayment of such bonds
becomes a moral commitment but not a legal obligation of the state or
municipality in question.     
 
  The Fund may purchase Municipal Bonds classified as "private activity bonds"
(in general, bonds that benefit non-governmental entities). Interest received
on certain tax-exempt securities that are classified as "private activity
bonds" may subject certain investors in the Fund to an alternative minimum tax.
There is no limitation on the percentage of the Fund's assets that may be
invested in Municipal Bonds that may subject certain investors to an
alternative minimum tax. See "Taxes--General."
 
  Also included within the general category of Municipal Bonds are
participation certificates issued by government authorities or entities to
finance the acquisition or construction of equipment, land and/or facilities.
The certificates represent participations in a lease, an installment purchase
contract or a conditional sales contract (hereinafter collectively referred to
as "lease obligations") relating to such equipment, land or facilities.
Although lease obligations typically do not constitute general obligations of
the issuer for which the issuer's unlimited taxing power is pledged, a lease
obligation frequently is backed by the issuer's covenant to budget for,
appropriate and make the payments due under the lease obligation. However,
certain lease obligations contain "non-appropriation" clauses, which provide
that the issuer has no obligation to make lease or installment purchase
payments in future years unless money is appropriated for such purpose on a
yearly basis. Although "non-appropriation" lease obligations are secured by the
lease property, disposition of the property in the event of foreclosure might
prove difficult. These securities represent a relatively new type of financing
that has not yet developed the depth of marketability associated with more
conventional securities.
 
  Federal tax legislation has limited the types and volume of bonds the
interest on which qualifies for a Federal income tax exemption. As a result,
this legislation and legislation that may be enacted in the future may affect
the availability of Municipal Bonds for investment by the Fund.
 
Other Investment Policies
 
  The Fund has adopted certain other policies as set forth below:
 
  Borrowings. The Fund is authorized to borrow money in amounts of up to 5% of
the value of its total assets at the time of such borrowings; provided,
however, that the Fund is authorized to borrow moneys in amounts of up to 33
1/3% of the value of its total assets at the time of such borrowings to finance
the repurchase of its own common stock pursuant to tender offers or otherwise
to redeem or repurchase shares of preferred stock or for temporary,
extraordinary or emergency purposes. Borrowings by the Fund (commonly known, as
with the issuance of preferred stock, as "leveraging") create an opportunity
for greater total return since the Fund will not be required to sell portfolio
securities to repurchase or redeem shares 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.
 
  When-Issued Securities and Delayed Delivery Transactions. The Fund 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 the Fund with payment and delivery taking
place in the future. The purchase will be recorded on the date the Fund enters
into the commitment, and the value of the obligation
 
                                       15
<PAGE>
 
will thereafter 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 securities having a
market value at all times at least equal to the amount of the commitment.
   
  Indexed and Inverse Floating Obligations. The Fund may invest in Municipal
Bonds yielding a return based on a particular index of value or interest rates.
For example, the Fund may invest in Municipal Bonds that pay interest based on
an index of Municipal Bond interest rates. The principal amount payable upon
maturity of certain Municipal Bonds also may be based on the value of an index.
To the extent the Fund invests in these types of Municipal Bonds, the Fund's
return on such Municipal Bonds will be subject to risk with respect to the
value of the particular index. Also, the Fund may invest in so-called "inverse
floating obligations" or "residual interest bonds" on which the interest rates
typically vary inversely with a short-term floating rate (which may be reset
periodically by a dutch auction, a remarketing agent, or by reference to a
short-term tax-exempt interest rate index). The Fund may purchase
synthetically-created inverse floating rate bonds evidenced by custodial or
trust receipts. Generally, income on inverse floating rate bonds will decrease
when short-term interest rates increase, and will increase when short-term
interest 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
that 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, the Fund may purchase inverse floating
obligations with shorter-term maturities or limitations on the extent to which
the interest rate may vary. The Investment Adviser believes that indexed and
inverse floating obligations represent a flexible portfolio management
instrument for the Fund that allows the Investment Adviser to vary the degree
of investment leverage relatively efficiently under different market
conditions.     
 
  Call Rights. The Fund may purchase a Municipal Bond issuer's right to call
all or a portion of such Municipal Bond for mandatory tender for purchase (a
"Call Right"). A holder of a Call Right may exercise such right to require a
mandatory tender for the purchase of related Municipal Bonds, subject to
certain conditions. A Call Right that is not exercised prior to the maturity of
the related Municipal Bond will expire without value. The economic effect of
holding both the Call Right and the related Municipal Bond is identical to
holding a Municipal Bond as a non-callable security.
 
  Repurchase Agreements. The Fund may invest in securities pursuant to
repurchase agreements. Repurchase agreements may be entered into only with a
member bank of the Federal Reserve System or a primary dealer in U.S.
Government securities or an affiliate thereof. Under such agreements, the
seller agrees, upon entering into the contract, to repurchase the security at a
mutually agreed-upon time and price, thereby determining the yield during the
term of the agreement. The Fund may not invest in repurchase agreements
maturing in more than seven days if such investments, together with all other
illiquid investments, would exceed 15% of the Fund's net assets. In the event
of default by the seller under a repurchase agreement, the Fund may suffer time
delays and incur costs or possible losses in connection with the disposition of
the underlying securities.
 
  In general, for Federal income tax purposes, repurchase agreements are
treated as collateralized loans secured by the securities "sold." Therefore,
amounts earned under such agreements will not be considered tax-exempt
interest.
 
                                       16

Options and Futures Transactions
 
  The 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 and options thereon. While the Fund's use of hedging
strategies is intended to reduce the volatility of the net asset value of the
common stock, the net asset value of the common stock will fluctuate. There can
be no assurance that the Fund's hedging transactions will be effective. In
addition, because of the anticipated leveraged nature of the common stock,
hedging transactions will result in a larger impact on the net asset value of
the common stock than would be the case if the common stock were not leveraged.
Furthermore, the Fund may only engage in hedging activities from time to time
and may not necessarily be engaging in hedging activities when movements in
interest rates occur. The Fund has no obligation to enter into hedging
transactions and may not do so.
 
  Certain Federal income tax requirements may limit the Fund's ability to
engage in hedging transactions. Gains from transactions in options and futures
contracts distributed to shareholders will be taxable as ordinary income or, in
certain circumstances, as long-term capital gains to shareholders. See "Taxes--
Tax Treatment of Options and Futures Transactions." In addition, in order to
obtain ratings of the preferred stock from one or more nationally recognized
statistical ratings organizations ("NRSROs"), the Fund may be required to limit
its use of hedging techniques in accordance with the specified guidelines of
such organizations.
 
  The following is a description of the options and futures transactions in
which the Fund may engage, limitations on the Fund's use of such transactions
and risks associated with these transactions. The investment policies with
respect to the hedging transactions of the Fund are not fundamental policies
and may be modified by the Board of Directors of the Fund without the approval
of the Fund's shareholders.
 
  Writing Covered Call Options. The Fund may write (i.e., sell) covered call
options with respect to Municipal Bonds it owns, thereby giving the holder of
the option the right to buy the underlying security covered by the option from
the Fund at the stated exercise price until the option expires. The 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.
 
  The Fund will receive 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, the 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 may serve as a
partial hedge against a decline in the price of the underlying security. The
Fund may engage in closing transactions in order to terminate outstanding
options that it has written.
 
  Purchase of Options. The Fund may purchase put options in connection with its
hedging activities. By buying a put the Fund has a right to sell the underlying
security at the exercise price, thus limiting the Fund's risk of loss through a
decline in the market value of the security until the put expires. The amount
of any appreciation in the value of the underlying security will be partially
offset by the amount of the premium paid for the put option and any related
transaction costs. Prior to its expiration, a put option may be sold in a
closing sale transaction; profit or loss from the sale will depend on whether
the amount received is more or less than the premium paid for the put option
plus the related transaction costs. A closing sale transaction cancels out the
Fund's position as the purchaser of an option by means of an offsetting sale of
an identical option prior to the
 
                                       17
<PAGE>
 
expiration of the option it has purchased. In certain circumstances, the Fund
may purchase call options on securities held in its portfolio on which it has
written call options or on securities that it intends to purchase. The Fund
will not purchase options on securities if, as a result of such purchase, the
aggregate cost of all outstanding options on securities held by the Fund would
exceed 5% of the market value of the Fund's total assets.
 
  Financial Futures Contracts and Options. The Fund is authorized to purchase
and sell certain financial futures contracts and options thereon solely for the
purpose of hedging its investments in Municipal Bonds against declines in value
and to hedge against increases in the cost of securities it intends to
purchase. A financial futures contract obligates the seller of a contract to
deliver and the purchaser of a contract to take delivery of the type of
financial instrument covered by the contract or, in the case of index-based
futures contracts, to make and accept a cash settlement, at a specific future
time for a specified price. A sale of financial futures contracts may provide a
hedge against a decline in the value of portfolio securities because such
depreciation may be offset, in whole or in part, by an increase in the value of
the position in the financial futures contracts. A purchase of financial
futures contracts may provide a hedge against an increase in the cost of
securities intended to be purchased because such appreciation may be offset, in
whole or in part, by an increase in the value of the position in the futures
contracts.
 
  The purchase or sale of a futures contract differs from the purchase or sale
of a security in that no price or premium is paid or received. Instead, an
amount of cash or securities acceptable to the broker 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 fluctuates making the long and short positions in the financial
futures contract more or less valuable.
 
  The Fund may purchase and sell financial futures contracts based on The Bond
Buyer Municipal Bond Index, a price-weighted measure of the market value of 40
large tax-exempt issues, and purchase and sell put and call options on such
financial futures contracts for the purpose of hedging Municipal Bonds that the
Fund holds or anticipates purchasing against adverse changes in interest rates.
The 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 the Board of Directors, the Fund also may
engage in transactions in other financial futures contracts, such as financial
futures contracts on other municipal bond indices that may become available, if
the Investment Adviser should determine that there is normally sufficient
correlation between the prices of such financial futures contracts and the
Municipal Bonds in which the Fund invests to make such hedging appropriate.
 
  Over-The-Counter Options. The Fund may engage in options and futures
transactions 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 prices and terms negotiated
by the buyer and seller. See "Restrictions on OTC Options" below for
information as to restrictions on the use of OTC options.
 
                                       18
<PAGE>
 
  Restrictions on OTC Options. The Fund will engage in transactions in OTC
options only with banks or dealers that have capital of at least $50 million or
whose obligations are guaranteed by an entity having capital of at least $50
million. Certain OTC options and assets used to cover OTC options written by
the Fund may be considered 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 might otherwise be
realized.
 
  Risk Factors in Options and Futures Transactions. Utilization of futures
transactions involves the risk of imperfect correlation in movements in the
price of financial futures contracts and movements in the price of the security
that is the subject of the hedge. If the price of the financial futures
contract moves more or less than the price of the security that is the subject
of the hedge, the Fund will experience a gain or loss that will not be
completely offset by movements in the price of such security. There is a risk
of imperfect correlation where the securities underlying financial futures
contracts have different maturities, ratings, geographic compositions or other
characteristics than the security being hedged. In addition, the correlation
may be affected by additions to or deletions from the index that serves as a
basis for a financial futures contract. 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 futures or options and Municipal
Bonds may be adversely affected by economic, political, legislative or other
developments that have a disparate impact on the respective markets for such
securities.
 
  Under regulations of the Commodity Futures Trading Commission ("CFTC"), the
futures trading activities described herein will not result in the Fund 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 financial futures contracts and options thereon (i) for bona fide hedging
purposes, without regard to the percentage of the Fund's assets committed to
margin and option premiums, and (ii) for non-hedging purposes if, immediately
thereafter, the sum of the amount of initial margin deposits on the Fund's
existing futures positions and option premiums entered into for non-hedging
purposes does not exceed 5% of the market value of the liquidation value of the
Fund's portfolio, after taking into account unrealized profits and unrealized
losses on any such transactions. Margin deposits may consist of cash or
securities acceptable to the broker and the relevant contract market.
 
  When the 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
liquid securities in a segregated account with the Fund's custodian so that the
amount so segregated plus the amount of initial and variation margin held in
the account of its broker equals the market value of the financial futures
contract, thereby ensuring that the use of such financial futures contract is
unleveraged.
 
  Certain risks are involved in options and futures transactions. The
Investment Adviser believes, however, that, because the Fund will engage in
options and futures transactions only for hedging purposes, the Fund's options
and futures portfolio strategies will not subject the Fund to those risks
associated with speculation in options and futures transactions.
 
  The volume of trading in the exchange markets with respect to Municipal Bond
options may be limited, and it is impossible to predict the amount of trading
interest that may exist in such options. In addition, there can be no assurance
that viable exchange markets will continue to be available.
 
                                       19
<PAGE>
 
  The Fund intends to enter into options and futures transactions, on an
exchange or in the over-the-counter market, only if there appears to be a
liquid secondary market for such options or futures. There can be no assurance,
however, that a liquid secondary market will exist at any specific time. Thus,
it may not be possible to close an options or futures transaction. The
inability to close options and futures positions also could have an adverse
impact on the Fund's ability to effectively hedge its portfolio. There is also
the risk of loss by the Fund of margin deposits or collateral in the event of
bankruptcy of a broker with which the Fund has an open position in an option or
financial futures contract.
 
  The liquidity of a secondary market in a financial futures contract may be
adversely affected by "daily price fluctuation limits" established by commodity
exchanges that limit the amount of fluctuation in a financial futures contract
price during a single trading day. Once the daily limit has been reached in the
contract, no trades may be entered into at a price beyond the limit, thus
preventing the liquidation of open futures positions. Prices have in the past
moved beyond the daily limit on a number of consecutive trading days.
 
  If it is not possible to close a financial futures position entered into by
the Fund, the Fund would continue to be required to make daily cash payments of
variation margin in the event of adverse price movements. In such a situation,
if the Fund has insufficient cash, it may have to sell portfolio securities to
meet daily variation margin requirements at a time when it may be
disadvantageous to do so.
 
  The successful use of these transactions also depends on the ability of the
Investment Adviser to forecast correctly the direction and extent of interest
rate movements within a given time frame. To the extent these rates remain
stable during the period in which a financial futures contract is held by the
Fund or move in a direction opposite to that anticipated, the Fund may realize
a loss on the hedging transaction that is not fully or partially offset by an
increase in the value of portfolio securities. As a result, the Fund's total
return for such period may be less than if it had not engaged in the hedging
transaction. Furthermore, the Fund will only engage in hedging transactions
from time to time and may not necessarily be engaged in hedging transactions
when movements in interest rates occur.
 
                  RISKS AND SPECIAL CONSIDERATIONS OF LEVERAGE
 
Effects of Leverage
 
  Within approximately three months after the completion of this offering, the
Fund intends to offer shares of preferred stock representing approximately 40%
of the Fund's capital immediately after the issuance of such preferred stock.
There can be no assurance, however, that preferred stock representing such
percentage of the Fund's capital will actually be issued. Issuing the preferred
stock will result in the leveraging of the common stock. Although the Fund's
Board of Directors has not yet determined the terms of the preferred stock
offering, the Fund anticipates that the preferred stock will pay dividends that
will be adjusted over either relatively short-term periods (generally seven to
28 days) or medium-term periods (up to five years). The dividend rate will be
based upon prevailing interest rates for debt obligations of comparable
maturity. The proceeds of the preferred stock offering will be invested in
longer-term obligations in accordance with the Fund's investment objective. The
expenses of the preferred stock, which will be borne by the Fund, will reduce
the net asset value of the common stock. Additionally, under certain
circumstances, when the Fund is required to allocate taxable income to holders
of preferred stock, the Fund anticipates that the terms of the preferred stock
will require the Fund to
 
                                       20
<PAGE>
 
make an additional distribution to such holders in an amount approximately
equal to the tax liability resulting from such allocation (an "Additional
Distribution"). Because under normal market conditions, obligations with longer
maturities produce higher yields than short-term and medium-term obligations,
the Investment Adviser believes that the spread inherent in the difference
between the short-term and medium-term rates (and any Additional Distribution)
paid by the Fund as dividends on the preferred stock and the longer-term rates
received by the Fund may provide holders of common stock with a potentially
higher yield.
 
  The use of leverage, however, involves certain risks to the holders of common
stock. For example, issuance of the preferred stock may result in higher
volatility of the net asset value of the common stock and potentially more
volatility in the market value of the common stock. In addition, changes in the
short-term and medium-term dividend rates on, and the amount of taxable income
allocable to, the preferred stock will affect the yield to holders of common
stock. Leverage will allow holders of common stock to realize a higher current
rate of return than if the Fund were not leveraged as long as the Fund, while
accounting for its costs and operating expenses, is able to realize a higher
net return on its investment portfolio than the then current dividend rate (and
any Additional Distribution) of the preferred stock. Similarly, since a pro
rata portion of the Fund's net realized capital gains are generally payable to
holders of common stock, the effect of leverage will be to increase the amount
of such gains distributed to holders of common stock. However, short-term,
medium-term and long-term interest rates change from time to time as do their
relationships 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 any or all of 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 substantially increase relative to the long-term
obligations in which the Fund may be invested. To the extent that the current
dividend rate (and any Additional Distribution) on the preferred stock
approaches the net return on the Fund's investment portfolio, the benefit of
leverage to holders of common stock will be decreased. If the current dividend
rate (and any Additional Distribution) on the preferred stock were to exceed
the net return on the Fund's portfolio, holders of common stock would receive a
lower rate of return than if the Fund were not leveraged. Similarly, since both
the cost of issuing the preferred stock and any decline in the value of the
Fund's investments (including investments purchased with the proceeds from any
preferred stock offering) will be borne entirely by holders of 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. If the Fund is liquidated, holders of preferred stock will be
entitled to receive liquidating distributions before any distribution is made
to holders of common stock.
 
  In an extreme case, a decline in net asset value could affect the Fund's
ability to pay dividends on the common stock. Failure to make such dividend
payments could adversely affect the Fund's qualification as a regulated
investment company under the Federal tax laws. See "Taxes." However, the Fund
intends to take all measures necessary to make common stock dividend payments.
If the Fund's current investment income is ever insufficient to meet dividend
payments on either the common stock or the preferred stock, the Fund may have
to liquidate certain of its investments. In addition, the Fund will have the
authority to redeem the preferred stock for any reason and may redeem all or
part of the preferred stock under the following circumstances:
 
  .  if the Fund anticipates that the leveraged capital structure will result
     in a lower rate of return for any significant amount of time to holders
     of common stock than that obtainable if the common stock were not
     leveraged,
 
                                       21
<PAGE>
 
  .  if the asset coverage for the preferred stock declines below 200% either
     as a result of a decline in the value of the Fund's portfolio
     investments or as a result of the repurchase of common stock in tender
     offers, or
 
  .  in order to maintain the asset coverage guidelines established by the
     NRSROs that have rated the preferred stock.
 
Redemption of the preferred stock 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.
 
  As discussed under "Investment Advisory and Management Arrangements," during
periods when the Fund has preferred stock outstanding, the fees paid the
Investment Adviser for investment advisory and management services will be
higher than if the Fund did not issue preferred stock because the fees paid
will be calculated on the basis of the Fund's average weekly net assets,
including proceeds from the sale of preferred stock.
   
  Assuming the use of leverage by issuing preferred stock (paying dividends at
a rate that generally will be adjusted every 28 days) in an amount
representing approximately 40% of the Fund's capital at an annual dividend
rate of 3.375% payable on such preferred stock based on market rates as of the
date of this prospectus, the annual return that the Fund's portfolio must
experience (net of expenses) in order to cover such dividend payments would be
1.35%.     
 
  The following table is designed to illustrate the effect on the return to a
holder of common stock of the leverage obtained by the issuance of preferred
stock representing approximately 40% of the Fund's capital, assuming
hypothetical annual returns on the Fund's portfolio of minus 10% to plus 10%.
As the table shows, leverage generally increases the return to stockholders
when portfolio return is positive and decreases the return when portfolio
return is negative. The figures appearing in the table are hypothetical and
actual returns may be greater or less than those appearing in the table.
 
<TABLE>   
   <S>                                                  <C>   <C>   <C>  <C> <C>
   Assumed Portfolio Return

   Corresponding Common Stock Return................... (19)% (11)% (2)%  6% 14%
</TABLE>    
 
  Leveraging the common stock cannot be fully achieved until preferred stock
is issued and the proceeds of such offering have been invested in long-term
Municipal Bonds.
 
Portfolio Management and Other Considerations
 
  If short-term or medium-term rates increase or other changes in market
conditions occur to the point where the Fund's leverage could adversely affect
holders of common stock as noted above (or in anticipation of such changes),
the Fund may attempt to shorten the average maturity of its investment
portfolio in order to offset the negative impact of leverage. The Fund also
may attempt to reduce the degree to which it is leveraged by redeeming
preferred stock pursuant to the Fund's Articles Supplementary, which establish
the rights and preferences of the preferred stock, or otherwise by purchasing
shares of preferred stock. Purchases and redemptions of preferred stock,
whether on the open market or in negotiated transactions, are subject to
 
                                      22
<PAGE>
 
limitations under the 1940 Act. In determining whether or not it is in the best
interest of the Fund and its stockholders to redeem or repurchase outstanding
preferred stock, the Board of Directors will take into account a variety of
factors, including the following:
 
  . market conditions,
 
  . the ratio of preferred stock to common stock, and
 
  . the expenses associated with such redemption or repurchase.
 
If market conditions subsequently change, the Fund may sell previously unissued
shares of preferred stock or shares of preferred stock that the Fund had issued
but later repurchased or redeemed.
 
  The Fund intends to apply for ratings of the preferred stock from one or more
NRSROs. In order to obtain these ratings, the Fund may be required to maintain
portfolio holdings that meet the specified guidelines of such organizations.
These guidelines may impose asset coverage requirements that are more stringent
than those imposed by the 1940 Act. The Fund does not anticipate that these
guidelines will impede the Investment Adviser from managing the Fund's
portfolio in accordance with the Fund's investment objective and policies.
Ratings on preferred stock issued by the Fund should not be confused with
ratings on the obligations held by the Fund.
 
  Under the 1940 Act, the Fund is not permitted to issue shares of preferred
stock unless immediately after such issuance the net asset value of the Fund's
portfolio is at least 200% of the liquidation value of the outstanding
preferred stock (expected to equal the original purchase price of the
outstanding shares of preferred stock plus any accumulated and unpaid dividends
thereon and any accumulated and unpaid Additional Distribution). In addition,
the Fund is not permitted to declare any cash dividend or other distribution on
its common stock unless, at the time of such declaration, the net asset value
of the Fund's portfolio (determined after deducting the amount of such dividend
or distribution) is at least 200% of the liquidation value of the outstanding
preferred stock. Under the Fund's proposed capital structure, assuming the sale
of shares of preferred stock representing approximately 40% of the Fund's
capital, the net asset value of the Fund's portfolio is expected to be
approximately 250% of the liquidation value of the Fund's preferred stock. To
the extent possible, the Fund intends to purchase or redeem shares of preferred
stock from time to time to maintain coverage of preferred stock of at least
200%.
 
                            INVESTMENT RESTRICTIONS
 
  The following are fundamental investment restrictions of the Fund and, prior
to issuance of the preferred stock, may not be changed without the approval of
the holders of a majority of the Fund's outstanding shares of common stock
(which for this purpose and under the 1940 Act means the lesser of (i) 67% of
the shares of common stock represented at a meeting at which more than 50% of
the outstanding shares of common stock are represented or (ii) more than 50% of
the outstanding shares). Subsequent to the issuance of the preferred stock, the
following investment restrictions may not be changed without the approval of a
majority of the outstanding shares of common stock and of the outstanding
shares of preferred stock, voting together as a class, and the approval of a
majority of the outstanding shares of preferred stock, voting separately as a
class. The Fund may not:
 
    1. Make investments for the purpose of exercising control or management.
 
                                       23
<PAGE>
 
    2. Purchase or sell real estate, commodities or commodity contracts;
  provided that the Fund may invest in securities secured by real estate or
  interests therein or issued by entities that invest in real estate or
  interest therein, and the Fund may purchase and sell financial futures
  contracts and options thereon.
 
    3. Issue senior securities or borrow money except as permitted by Section
  18 of the 1940 Act.
 
    4. Underwrite securities of other issuers except insofar as the Fund may
  be deemed an underwriter under the Securities Act of 1933, as amended, in
  selling portfolio securities.
 
    5. Make loans to other persons, except that the Fund may purchase
  Municipal Bonds and other debt securities and enter into repurchase
  agreements in accordance with its investment objective, policies and
  limitations.
 
    6. 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 that, for purposes of this restriction, states, municipalities and
  their political subdivisions are not considered to be part of any industry.
 
Additional investment restrictions adopted by the Fund, which may be changed by
the Board of Directors without shareholder approval, provide that the Fund may
not:
 
    a. Purchase securities of other investment companies, except to the
  extent that such purchases are permitted by applicable law. Applicable law
  currently prohibits the Fund from purchasing the securities of other
  investment companies except if immediately thereafter not more than (i) 3%
  of the total outstanding voting stock of such company is owned by the Fund,
  (ii) 5% of the Fund's total assets, taken at market value, would be
  invested in any one such company, (iii) 10% of the Fund's total assets,
  taken at market value, would be invested in such securities, and (iv) the
  Fund, together with other investment companies having the same investment
  adviser and companies controlled by such companies, owns not more than 10%
  of the total outstanding stock of any one closed-end investment company.
 
    b. 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
  (3) above or except as may be necessary in connection with transactions in
  financial futures contracts and options thereon.
 
    c. Purchase any securities on margin, except that the Fund may obtain
  such short-term credit as may be necessary for the clearance of purchases
  and sales of portfolio securities (the deposit or payment by the Fund of
  initial or variation margin in connection with financial futures contracts
  and options thereon is not considered the purchase of a security on
  margin).
 
    d. 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 and may purchase and sell Call Rights to require
  mandatory tender for the purchase of related Municipal Bonds.
 
  If a percentage restriction on the investment or use of assets set forth
above is adhered to at the time a transaction is effected, later changes in
percentages resulting from changing values will not be considered a violation.
 
  The Investment Adviser of the Fund and Merrill Lynch, Pierce, Fenner & Smith
Incorporated ("Merrill Lynch") are owned and controlled by Merrill Lynch & Co.
("ML & Co."). Because of the affiliation of Merrill Lynch with the Investment
Adviser, the Fund is prohibited from engaging in certain transactions
 
                                       24
<PAGE>
 
involving Merrill Lynch except pursuant to an exemptive order or otherwise in
compliance with the provisions of the 1940 Act and the rules and regulations
thereunder. Included among such restricted transactions will be purchases from
or sales to Merrill Lynch of securities in transactions in which it acts as
principal. An exemptive order has been obtained that permits the Fund to effect
principal transactions with Merrill Lynch in high quality, short-term, tax-
exempt securities subject to conditions set forth in such order. The Fund may
consider in the future requesting an order permitting other principal
transactions with Merrill Lynch, but there can be no assurance that such
application will be made and, if made, that such order would be granted.

                INVESTMENT ADVISORY AND MANAGEMENT ARRANGEMENTS
   
  The Investment Adviser, which is owned and controlled by ML & Co., a
financial services holding company and the parent of Merrill Lynch, provides
the Fund with investment advisory and management services. The Merrill Lynch
Asset Management Group (which includes the Investment Adviser) acts as the
investment adviser to more than 100 registered investment companies and offers
investment advisory services to individuals and institutional accounts. As of
March 1999, the Merrill Lynch Asset Management Group had a total of
approximately $515 billion in investment company and other portfolio assets
under management (approximately $40 billion of which were invested in municipal
securities). This amount includes assets managed for certain affiliates of the
Investment Adviser. The Investment Adviser is a limited partnership, the
partners of which are ML & Co. and Princeton Services. The principal business
address of the Investment Adviser is 800 Scudders Mill Road, Plainsboro, New
Jersey 08536.     
 
  The Investment Advisory Agreement provides that, subject to the supervision
of the Board of Directors of the Fund, the Investment Adviser is responsible
for the actual management of the Fund's portfolio. The responsibility for
making decisions to buy, sell or hold a particular security rests with the
Investment Adviser, subject to review by the Board of Directors.
   
  The Investment Adviser provides the portfolio management for the Fund. Such
portfolio management will consider analyses from various sources (including
brokerage firms with which the Fund does business), make the necessary
investment decisions, and place orders for transactions accordingly. The
Investment Adviser will also be responsible for the performance of certain
administrative and management services for the Fund. William R. Bock is the
portfolio manager of the Fund and is primarily responsible for the Fund's day-
to-day management.     
   
  For the services provided by the Investment Adviser under the Investment
Advisory Agreement, the Fund will pay a monthly fee at an annual rate of 0.55
of 1% of the Fund's average weekly net assets (i.e., the     
 
                                       27
<PAGE>
 
average weekly value of the total assets of the Fund, including proceeds from
the issuance of shares of preferred stock, minus the sum of accrued liabilities
of the Fund and accumulated dividends on the shares of preferred stock). 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.
 
  The Investment Advisory Agreement obligates the Investment Adviser 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 the
Investment Adviser or any of its affiliates. The 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, if any, stock certificates and shareholder reports, charges of the
custodian and the transfer and dividend disbursing agent and registrar, fees
and expenses with respect to the issuance of preferred stock, Securities and
Exchange Commission fees, fees and expenses of non-interested 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. Accounting services are provided to the Fund by
the Investment Adviser, and the Fund reimburses the Investment Adviser for its
costs in connection with such services.
 
  Unless earlier terminated as described below, the Investment Advisory
Agreement will remain in effect for a period of two years from the date of
execution and will remain in effect from year to year thereafter if approved
annually (a) by the Board of Directors of the Fund or by a majority of the
outstanding shares of the Fund and (b) by a majority of the Directors who are
not parties to such contract or interested persons (as defined in the 1940 Act)
of any such party. Such contract is not assignable and may be terminated
without penalty on 60 days' written notice at the option of either party
thereto or by the vote of the shareholders of the Fund.
 
  Securities held by the Fund may also be held by, or be appropriate
investments for, other funds or investment advisory clients for which the
Investment Adviser or its affiliates act as an adviser. Because of different
objectives or other factors, a particular security may be bought for an
advisory client when other clients are selling the same security. If purchases
or sales of securities by the Investment Adviser for the Fund or other funds
for which it acts as investment adviser or for other advisory clients arise for
consideration at or about the same time, transactions in such securities will
be made, insofar as feasible, for the respective funds and clients in a manner
deemed equitable to all. Transactions effected by the Investment Adviser (or
its affiliates) on behalf of more than one of its clients during the same
period may increase the demand for securities being purchased or the supply of
securities being sold, causing an adverse effect on price.
 
Code of Ethics
 
  The Board of Directors of the Fund has adopted a Code of Ethics pursuant to
Rule 17j-1 under the 1940 Act that incorporates the Code of Ethics of the
Investment Adviser (together, the "Codes"). The Codes significantly restrict
the personal investing activities of all employees of the Investment Adviser
and, as described below, impose additional, more onerous, restrictions on Fund
investment personnel.
 
                                       28
<PAGE>
 
  The Codes require that all employees of the Investment Adviser preclear any
personal securities investment (with limited exceptions, such as U.S.
Government securities). The preclearance requirement and associated procedures
are designed to identify any substantive prohibition or limitation applicable
to the proposed investment. The substantive restrictions applicable to all
employees of the Investment Adviser include a ban on acquiring any securities
in a "hot" initial public offering and a prohibition from profiting on short-
term trading securities. In addition, no employee may purchase or sell any
security that at the time is being purchased or sold (as the case may be), or
to the knowledge of the employee is being considered for purchase or sale, by
any fund advised by the Investment Adviser. Furthermore, the Codes provide for
trading "blackout periods" that prohibit trading by investment personnel of the
Fund within periods of trading by the Fund in the same (or equivalent) security
(15 or 30 days depending upon the transaction).
 
                             PORTFOLIO TRANSACTIONS
 
  Subject to policies established by the Board of Directors of the Fund, the
Investment Adviser is primarily responsible for the execution of the Fund's
portfolio transactions. In executing such transactions, the Investment Adviser
seeks to obtain the best results for the Fund, taking into account such factors
as price (including the applicable brokerage commission or dealer spread), size
of order, difficulty of execution and operational facilities of the firm
involved and the firm's risk in positioning a block of securities. While the
Investment Adviser generally seeks reasonably competitive commission rates, the
Fund does not necessarily pay the lowest commission or spread available.
 
  The Fund has no obligation to deal with any broker or dealer in the execution
of transactions in portfolio securities. Subject to providing the best price
and execution, securities firms that provide investment research to the
Investment Adviser, including Merrill Lynch, may receive orders for
transactions by the Fund. Research information provided to the Investment
Adviser by securities firms is supplemental. It does not replace or reduce the
level of services performed by the Investment Adviser and the expenses of the
Investment Adviser will not be reduced because it receives supplemental
research information.
 
  The Fund invests in securities traded in the over-the-counter markets, and
the Fund intends to deal directly with dealers who make markets in the
securities involved, except in those circumstances where better prices and
execution are available elsewhere. Under the 1940 Act, except as permitted by
exemptive order, persons affiliated with the Fund, including Merrill Lynch, are
prohibited from dealing with the Fund as principal in the purchase and sale of
securities. Since transactions in the over-the-counter market usually involve
transactions with dealers acting as principals for their own accounts, the Fund
does not deal with Merrill Lynch and its affiliates in connection with such
transactions except that, pursuant to exemptive orders obtained by the
Investment Adviser, the Fund may engage in principal transactions with Merrill
Lynch in high quality, short-term, tax-exempt securities. See "Investment
Restrictions." However, affiliated persons of the Fund, including Merrill
Lynch, serve as its brokers in certain over-the-counter transactions conducted
on an agency basis.
 
  The Fund also may purchase tax-exempt debt instruments in individually
negotiated transactions with the issuers. Because an active trading market may
not exist for such securities, the prices that the Fund may pay for these
securities or receive on their resale may be lower than that for similar
securities with a more liquid market.

  The Fund may dispose of securities without regard to the time they have been
held when such action, for defensive or other reasons, appears advisable to the
Investment Adviser. While it is not possible to predict turnover rates with any
certainty, presently it is anticipated that the Fund's annual portfolio
turnover rate, under normal circumstances, should be less than 100%. (The
portfolio turnover rate is calculated by dividing the lesser of purchases or
sales of portfolio securities for the particular fiscal year by the monthly
average of the value of the portfolio securities owned by the Fund during the
particular fiscal year. For purposes of determining this rate, all securities
whose maturities at the time of acquisition are one year or less are excluded.)
A high portfolio turnover rate results in greater transaction costs, which are
borne directly by the Fund, and also has certain tax consequences for
shareholders.     
 
                          DIVIDENDS AND DISTRIBUTIONS
 
  The Fund intends to distribute all its net investment income. Dividends from
such net investment income will be declared and paid monthly to holders of
common stock. It is expected that the Fund will commence paying dividends to
holders of common stock within approximately 90 days of the date of this
prospectus. From and after issuance of the preferred stock, monthly
distributions to holders of common stock normally will consist of substantially
all net investment income remaining after the payment of dividends (and any
Additional Distribution) on the preferred stock. All net realized capital
gains, if any, will be distributed pro rata at least annually to holders of
common stock and any preferred stock. While any shares of preferred stock are
outstanding, the Fund may not declare any cash dividend or other distribution
on its common stock, unless at the time of such declaration, (i) all
accumulated preferred stock dividends, including any Additional Distribution,
have been paid, and (ii) 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 outstanding preferred stock
(expected to equal the original purchase price of the outstanding shares of
preferred stock plus any accumulated and unpaid dividends thereon and any
accumulated but unpaid Additional Distribution). If the Fund's ability to make
distributions on its common stock is limited, such limitation could under
certain circumstances impair the ability of the Fund to maintain its
qualification for taxation as a regulated investment company, which would have
adverse tax consequences for holders of common stock. See "Taxes."
 
  See "Automatic Dividend Reinvestment Plan" for information concerning the
manner in which dividends and distributions to holders of common stock may be
automatically reinvested in shares of common stock of the Fund. Dividends and
distributions may be taxable to shareholders under certain circumstances as
discussed below, whether they are reinvested in shares of the Fund or received
in cash.
 
                                     TAXES
 
General
 
  The Fund intends to elect and to qualify for the special tax treatment
afforded regulated investment companies ("RICs") under the Internal Revenue
Code of 1986, as amended (the "Code"). As long as it so qualifies, in any
taxable year in which it distributes at least 90% of its taxable net income and
90% of its tax-exempt net income (see below), the Fund (but not its
shareholders) will not be subject to Federal income tax to the extent that it
distributes its net investment income and net realized capital gains. The Fund
intends to distribute substantially all of such income.
 
                                       30
<PAGE>
 
  The Code requires a RIC to pay a nondeductible 4% excise tax to the extent
the RIC does not distribute, during each calendar year, 98% of its ordinary
income, determined on a calendar year basis, and 98% of its capital gains,
determined, in general, on an October 31 year-end, plus certain undistributed
amounts from previous years. The required distributions, however, are based
only on the taxable income of a RIC. The excise tax, therefore, generally will
not apply to the tax-exempt income of a RIC, such as the Fund, that pays
exempt-interest dividends.
 
  The Fund intends to qualify to pay "exempt-interest dividends" as defined in
Section 852(b)(5) of the Code. Under such section if, at the close of each
quarter of its taxable year, at least 50% of the value of its total assets
consists of obligations exempt from Federal income tax ("tax-exempt
obligations") under Section 103(a) of the Code (relating generally to
obligations of a state or local governmental unit), the Fund shall be qualified
to pay exempt-interest dividends to its shareholders. Exempt-interest dividends
are dividends or any part thereof paid by the Fund that are attributable to
interest on tax-exempt obligations and designated by the Fund as exempt-
interest dividends in a written notice mailed to the Fund's shareholders within
60 days after the close of its taxable year. To the extent that the dividends
distributed to the Fund's shareholders are derived from interest income exempt
from tax under Code Section 103(a) and are properly designated as exempt-
interest dividends, they will be excludable from a shareholder's gross income
for Federal income tax purposes. Exempt-interest dividends are included,
however, in determining the portion, if any, of a person's social security and
railroad retirement benefits subject to Federal income taxes. Each shareholder
is advised to consult a tax adviser with respect to whether exempt-interest
dividends retain the exclusion under Code Section 103(a) if such shareholder
would be treated as a "substantial user" or "related person" under Code Section
147(a) with respect to property financed with the proceeds of an issue of
"industrial development bonds" or "private activity bonds," if any, held by the
Fund.
 
  To the extent that the Fund's distributions are derived from interest on its
taxable investments or from an excess of net short-term capital gains over net
long-term capital losses ("ordinary income dividends"), such distributions will
be considered taxable ordinary income for Federal income tax purposes.
Distributions, if any, from an excess of net long-term capital gains over net
short-term capital losses derived from the sale of securities or from certain
transactions in futures or options ("capital gain dividends") are taxable as
long-term capital gains for Federal income tax purposes, regardless of the
length of time the shareholder has owned Fund shares. Certain categories of
capital gains are taxable at different rates. Generally not later than 60 days
after the close of its taxable year, the Fund will provide its shareholders
with a written notice designating the amounts of any exempt-interest dividends
and capital gain dividends, as well as any amount of capital gain dividends in
the different categories of capital gain referred to above. Distributions by
the Fund, whether from exempt-income, ordinary income or capital gains, are not
eligible for the dividends received deduction allowed to corporations under the
Code.
 
  All or a portion of the Fund's gain from the sale or redemption of tax-exempt
obligations purchased at a market discount will be treated as ordinary income
rather than capital gain. This rule may increase the amount of ordinary income
dividends received by shareholders.
 
  Distributions in excess of the Fund's earnings and profits will first reduce
the adjusted tax basis of a holder's shares and, after such adjusted tax basis
is reduced to zero, will constitute capital gains to such holder (assuming the
shares are held as a capital asset). Any loss upon the sale or exchange of Fund
shares held for six months or less will be disallowed to the extent of any
exempt-interest dividends received by the shareholder. In addition, any such
loss that is not disallowed under the rule stated above will be treated as
long-
 
                                       31
<PAGE>
 
term capital loss to the extent of any capital gain dividends received by the
shareholder. If the Fund pays a dividend in January that was declared in the
previous October, November or December to shareholders of record on a specified
date in one of such months, then such dividend will be treated for tax purposes
as being paid by the Fund and received by its shareholders on December 31 of
the year in which such dividend was declared.
 
  The Internal Revenue Service ("Service") has taken the position in a revenue
ruling that if a RIC has two or more classes of shares, it may designate
distributions made to each class in any year as consisting of no more than such
class's proportionate share of particular types of income, including exempt-
interest income and net long-term capital gains. A class's proportionate share
of a particular type of income is determined according to the percentage of
total dividends paid by the RIC during such year that was paid to such class.
Consequently, when common stock and one or more series of preferred stock are
outstanding, the Fund intends to designate distributions made to the classes as
consisting of particular types of income in accordance with each class's
proportionate share of such income. Thus, the Fund will designate dividends
paid as exempt-interest dividends in a manner that allocates such dividends
among the holders of common stock and series of preferred stock in proportion
to the total dividends paid to each class during the taxable year, or otherwise
as required by applicable law. Capital gain dividends will similarly be
allocated among the classes in proportion to the total dividends paid to each
class during the taxable year, or otherwise as required by applicable law. When
capital gain or other taxable income is allocated to holders of preferred stock
pursuant to the allocation rules described above, the terms of the preferred
stock may require the Fund to make an additional distribution to or otherwise
compensate such holders for the tax liability resulting from such allocation.
 
  The Code subjects interest received on certain otherwise tax-exempt
securities to an alternative minimum tax. The alternative minimum tax will
apply to interest received on certain "private activity bonds" issued after
August 7, 1986. Private activity bonds are bonds that, although tax-exempt, are
used for purposes other than those generally performed by governmental units
and that 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" that could subject certain investors in such
bonds, including shareholders of the Fund, to an increased alternative minimum
tax. The Fund intends to purchase such "private activity bonds" and will report
to shareholders within 60 days after calendar year-end the portion of its
dividends declared during the year that constitutes an item of tax preference
for alternative minimum tax purposes. The Code further provides that
corporations are subject to an alternative minimum tax based, in part, on
certain differences between taxable income as adjusted for other tax
preferences and the corporation's "adjusted current earnings," which more
closely reflect a corporation's economic income. Because an exempt-interest
dividend paid by the Fund will be included in adjusted current earnings, a
corporate shareholder may be required to pay an alternative minimum tax on
exempt-interest dividends paid by the Fund.
 
  The Fund may invest in instruments the return on which includes
nontraditional features such as indexed principal or interest payments
("nontraditional instruments"). These instruments may be subject to special tax
rules under which the Fund may be required to accrue and distribute income
before amounts due under the obligations are paid. In addition, it is possible
that all or a portion of the interest payments on such nontraditional
instruments could be recharacterized as taxable ordinary income.
 
  If at any time when shares of preferred stock are outstanding the Fund does
not meet the asset coverage requirements of the 1940 Act, the Fund will be
required to suspend distributions to holders of common stock until the asset
coverage is restored. See "Dividends and Distributions." This may prevent the
Fund from distributing at least 90% of its net investment income and may,
therefore, jeopardize the Fund's qualification
 
                                       32
<PAGE>
 
for taxation as a RIC. If the Fund were to fail to qualify as a RIC, some or
all of the distributions paid by the Fund would be fully taxable for Federal
income tax purposes. Upon any failure to meet the asset coverage requirements
of the 1940 Act, the Fund, in its sole discretion, may redeem shares of
preferred stock in order to maintain or restore the requisite asset coverage
and avoid the adverse consequences to the Fund and its shareholders of failing
to qualify as a RIC. There can be no assurance, however, that any such action
would achieve such objectives.
 
  As noted above, the Fund must distribute annually at least 90% of its net
taxable and tax-exempt interest income. A distribution will only be counted for
this purpose if it qualifies for the dividends paid deduction under the Code.
Some types of preferred stock that the Fund currently contemplates issuing may
raise an issue as to whether distributions on such preferred stock are
"preferential" under the Code and, therefore, not eligible for the dividends
paid deduction. The Fund intends to issue preferred stock that counsel advises
will not result in the payment of a preferential dividend and may seek a
private letter ruling from the Service to that effect. If the Fund ultimately
relies solely on a legal opinion when it issues such preferred stock, there is
no assurance that the Service would agree that dividends on the preferred stock
are not preferential. If the Service successfully disallowed the dividends paid
deduction for dividends on the preferred stock, the Fund could be disqualified
as a RIC. In this case, dividends on the common stock would not be exempt from
Federal income taxes. Additionally, the Fund would be subject to the
alternative minimum tax.
 
  The value of shares acquired pursuant to the Fund's dividend reinvestment
plan will generally be excluded from gross income to the extent that the cash
amount reinvested would be excluded from gross income. If, when the Fund's
shares are trading at a premium over net asset value, the Fund issues shares
pursuant to the dividend reinvestment plan that have a greater fair market
value than the amount of cash reinvested, it is possible that all or a portion
of such discount (which may not exceed 5% of the fair market value of the
Fund's shares) could be viewed as a taxable distribution. If the discount is
viewed as a taxable distribution, it is also possible that the taxable
character of this discount would be allocable to all of the shareholders,
including shareholders who do not participate in the dividend reinvestment
plan. Thus, shareholders who do not participate in the dividend reinvestment
plan, as well as dividend reinvestment plan participants, might be required to
report as ordinary income a portion of their distributions equal to their
allocable share of the discount.
 
  Ordinary income dividends paid to shareholders who are nonresident aliens or
foreign entities will be subject to a 30% United States withholding tax under
existing provisions of the Code applicable to foreign individuals and entities
unless a reduced rate of withholding or a withholding exemption is provided
under applicable treaty law. Nonresident shareholders are urged to consult
their own tax advisers concerning the applicability of the United States
withholding tax.
 
  Under certain Code provisions, some taxpayers may be subject to 31%
withholding tax on certain ordinary income dividends and on capital gain
dividends and redemption payments ("backup withholding"). Generally,
shareholders subject to backup withholding are those for whom no certified
taxpayer identification number is on file with the 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 investor is not otherwise subject to backup withholding.
 
  The Code provides that every shareholder required to file a tax return must
include for information purposes on such return the amount of exempt-interest
dividends received from all sources (including the Fund) during the taxable
year.
 
                                       33

Tax Treatment of Options and Futures Transactions
 
  The Fund may purchase or sell municipal bond index financial futures
contracts and interest rate financial futures contracts on U.S. Government
securities. The Fund may also purchase and write call and put options on such
financial futures contracts. In general, unless an election is available to the
Fund or an exception applies, such options and financial futures contracts that
are "Section 1256 contracts" will be "marked to market" for Federal income tax
purposes at the end of each taxable year, i.e., each such option or financial
futures contract will be treated as sold for its fair market value on the last
day of the taxable year, and any gain or loss attributable to Section 1256
contracts will be 60% long-term and 40% short-term capital gain or loss.
Application of these rules to Section 1256 contracts held by the Fund may alter
the timing and character of distributions to shareholders. The mark-to-market
rules outlined above, however, will not apply to certain transactions entered
into by the Fund solely to reduce the risk of changes in price or interest
rates with respect to its investments.
 
  Code Section 1092, which applies to certain "straddles," may affect the
taxation of the Fund's sales of securities and transactions in financial
futures contracts and related options. Under Section 1092, the Fund may be
required to postpone recognition for tax purposes of losses incurred in certain
sales of securities and certain closing transactions in financial futures
contracts or the related options.
 
                               ----------------
 
  The foregoing is a general and abbreviated summary of the applicable
provisions of the Code and Treasury Regulations presently in effect. For the
complete provisions, reference should be made to the pertinent Code sections,
the Treasury Regulations promulgated thereunder. The Code and the Treasury
Regulations are subject to change by legislative, judicial or administrative
action either prospectively or retroactively.
 
  Shareholders are urged to consult their tax advisers regarding specific
questions as to Federal, state, local or foreign taxes.
 
                      AUTOMATIC DIVIDEND REINVESTMENT PLAN
   
  Pursuant to the Fund's Automatic Dividend Reinvestment Plan (the "Plan"),
unless a holder of common stock otherwise elects, all dividend and capital
gains distributions will be automatically reinvested by The Bank of New York,
as agent for shareholders in administering the Plan (the "Plan Agent"), in
additional shares of common stock of the Fund. Holders of common stock who
elect not to participate in the Plan will receive all distributions in cash
paid by check mailed directly to the shareholder of record (or, if the shares
are held in street or other nominee name, then to such nominee) by The Bank of
New York, as dividend paying agent. Such participants 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 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 or
resumption will be effective with respect to any subsequently declared dividend
or distribution.     
 
  Whenever the Fund declares an income dividend or a capital gains distribution
(collectively, referred to as "dividends") payable either in shares or in cash,
non-participants in the Plan will receive cash, and participants in the Plan
will receive the equivalent in shares of common stock. The shares will be
acquired by the Plan
 
                                       34
<PAGE>
 
Agent for the participant's account, depending upon the circumstances described
below, either (i) through receipt of additional unissued but authorized shares
of common stock from the Fund ("newly issued shares") or (ii) by purchase of
outstanding shares of common stock on the open market ("open-market purchases")
on the New York Stock Exchange (the "NYSE") or elsewhere. If on the payment
date for the dividend, the net asset value per share of the common stock is
equal to or less than the market price per share of the common stock plus
estimated brokerage commissions (such condition being referred to herein as
"market premium"), the Plan Agent will invest the dividend amount in newly
issued shares on behalf of the participant. The number of newly issued shares
of common stock to be credited to the participant's account will be determined
by dividing the dollar amount of the dividend by the net asset value per share
on the date the shares are issued, provided that the maximum discount from the
then current market price per share on the date of issuance may not exceed 5%.
If on the dividend payment date the net asset value per share is greater than
the market value (such condition being referred to herein as "market
discount"), the Plan Agent will invest the dividend amount in shares acquired
on behalf of the participant in open-market purchases. Prior to the time the
shares of common stock commence trading on the NYSE, participants in the Plan
will receive any dividends in newly issued shares.
 
  In the event of a market discount on the dividend payment date, the Plan
Agent will have until the last business day before the next date on which the
shares trade on an "ex-dividend" basis or in no event more than 30 days after
the dividend payment date (the "last purchase date") to invest the dividend
amount in shares acquired in open-market purchases. It is contemplated that the
Fund will pay monthly income dividends. Therefore, the period during which
open-market purchases can be made will exist only from the payment date on the
dividend through the date before the next "ex-dividend" date, which typically
will be approximately ten days. If, before the Plan Agent has completed its
open-market purchases, the market price of a share of common stock exceeds the
net asset value per share, the average per share purchase prices 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 will cease making open-market purchases and
will invest the uninvested portion of the dividend amount in newly issued
shares at the close of business on the last purchase date.
 
  The Plan Agent maintains all shareholders' accounts in the Plan and furnishes
written confirmation of all transactions in the account, including information
needed by shareholders for tax records. Shares in the account of each Plan
participant will be held by the Plan Agent in non-certificated form in the name
of the participant and each shareholder's proxy will include those shares
purchased or received pursuant to the Plan. The Plan Agent will forward all
proxy solicitation materials to participants and vote proxies for shares held
pursuant to the Plan in accordance with the instructions of the participants.
 
  In the case of shareholders such as banks, brokers or nominees that 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 shareholders as representing the total amount registered in the
record shareholder's name and held for the account of beneficial owners who are
to participate in the Plan.
 
  There will be no brokerage charges with respect to shares issued directly by
the Fund as a result of dividends or capital gains distributions payable either
in shares or in cash. However, each participant will pay a
 
                                       35
<PAGE>
 
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 will not relieve
participants of any Federal, state or local income tax that may be payable (or
required to be withheld) on such dividends. See "Taxes."
 
  Shareholders participating in the Plan may receive benefits not available to
shareholders not participating in the Plan. If the market price plus
commissions of the Fund's shares is above the net asset value, participants in
the Plan will receive shares of the Fund at less than they could otherwise
purchase them and will have shares with a cash value greater than the value of
any cash distribution they would have received on their shares. If the market
price plus commissions is below the net asset value, participants will receive
distributions 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 the Fund does not redeem its
shares, the price on resale may be more or less than the net asset value. See
"Taxes" for a discussion of tax consequences of the Plan.
 
  Experience under the Plan may indicate that changes are desirable.
Accordingly, the Fund reserves the right to amend or terminate the Plan. There
is no direct service charge to participants in the Plan; however, the Fund
reserves the right to amend the Plan to include a service charge payable by the
participants.
   
  All correspondence concerning the Plan should be directed to the Plan Agent
at 101 Barclay Street, New York, New York 10286.     
 
                         MUTUAL FUND INVESTMENT OPTION
 
  Purchasers of shares of common stock of the Fund through Merrill Lynch in
this offering will have an investment option consisting of the right to
reinvest the net proceeds from a sale of such shares (the "Original Shares") in
Class D initial sales charge shares of certain Merrill Lynch-sponsored open-end
mutual funds ("Eligible Class D Shares") at their net asset value, without the
imposition of the initial sales charge, if the conditions set forth below are
satisfied. First, the sale of the Original Shares must be made through Merrill
Lynch, and the net proceeds therefrom must be immediately reinvested in
Eligible Class D Shares. Second, the Original Shares must have been either
acquired in this offering or be shares representing reinvested dividends from
shares of common stock acquired in this offering. Third, the Original Shares
must have been continuously maintained in a Merrill Lynch securities account.
Fourth, there must be a minimum purchase of $250 to be eligible for the
investment option. Class D shares of the mutual funds are subject to an account
maintenance fee at an annual rate of up to 0.25% of the average daily net asset
value of such mutual fund. The Eligible Class D Shares may be redeemed at any
time at the next determined net asset value, subject in certain cases to a
redemption fee. Prior to the time the shares of common stock commence trading
on the NYSE, the distributor for the mutual funds will advise Merrill Lynch
Financial Consultants as to those mutual funds that offer the investment option
described above.
 
                                       36
<PAGE>
 
                                NET ASSET VALUE
 
  Net asset value per share of common stock is determined as of 15 minutes
after the close of business on the NYSE (generally, the NYSE closes at 4:00
p.m., Eastern time) on the last business day in each week. For purposes of
determining the net asset value of a share of common stock, the value of the
securities held by the 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
preferred stock is divided by the total number of shares of common stock
outstanding at such time. Expenses, including the fees payable to the
Investment Adviser, are accrued daily.
 
  The Municipal Bonds in which the Fund invests are traded primarily in the
over-the-counter markets. In determining net asset value, the 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 the Fund
under the general supervision of the Board of Directors. The Board of Directors
has determined in good faith that the use of a pricing service is a fair method
of determining the valuation of portfolio securities. 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.
 
  The Fund determines and makes available for publication the net asset value
of its common stock weekly. Currently, the net asset values of shares of
publicly traded closed-end investment companies investing in debt securities
are published in Barron's, the Monday edition of The Wall Street Journal, and
the Monday and Saturday editions of The New York Times.
 
                          DESCRIPTION OF CAPITAL STOCK
 
  The Fund is authorized to issue 200,000,000 shares of capital stock, par
value $.10 per share, all of which shares are initially classified as common
stock. The Board of Directors is authorized, however, to classify or reclassify
any unissued shares of capital stock by setting or changing the preferences,
conversion or other rights, voting powers, restrictions, limitations as to
dividends, qualifications, or terms or conditions of redemption. Within
approximately three months after completion of the offering of the common stock
described herein, the Fund intends to reclassify an amount of unissued common
stock as preferred stock and at that time to offer shares of preferred stock
representing approximately 40% of the Fund's capital immediately after the
issuance of such preferred stock. There is no assurance that such preferred
stock will be issued.
 
Common Stock
 
  Shares of common stock, when issued and outstanding, will be fully paid and
non-assessable. Shareholders are entitled to share pro rata in the net assets
of the Fund available for distribution to shareholders upon liquidation of the
Fund. Shareholders are entitled to one vote for each share held.
 
  So long as any shares of the Fund's preferred stock are outstanding, holders
of common stock will not be entitled to receive any net income of or other
distributions from the Fund unless all accumulated dividends on
 
                                       37
<PAGE>
 
preferred stock have been paid and unless asset coverage (as defined in the
1940 Act) with respect to preferred stock would be at least 200% after giving
effect to such distributions. See "Preferred Stock" below.
 
  The Fund will send unaudited reports at least semi-annually and audited
annual financial statements to all of its shareholders.
 
  The Investment Adviser provided the initial capital for the Fund by
purchasing 6,667 shares of common stock of the Fund for $100,005. As of the
date of this prospectus, the Investment Adviser owned 100% of the outstanding
shares of common stock of the Fund. The Investment Adviser may be deemed to
control the Fund until such time as it owns less than 25% of the outstanding
shares of the Fund.
 
Preferred Stock
 
  It is anticipated that the Fund's shares of preferred stock will be issued in
one or more series, with rights as determined by the Board of Directors, by
action of the Board of Directors without the approval of the holders of common
stock. Under the 1940 Act, the Fund is permitted to have outstanding more than
one series of preferred stock so long as no single series has a priority over
another series as to the distribution of assets of the Fund or the payment of
dividends. Holders of common stock have no preemptive right to purchase any
shares of preferred stock that might be issued. It is anticipated that the net
asset value per share of the preferred stock will equal its original purchase
price per share plus accumulated dividends per share.
 
  The Fund's Board of Directors has declared its intention to authorize an
offering of shares of preferred stock (representing approximately 40% of the
Fund's capital immediately after the issuance of such preferred stock) within
approximately three months after completion of the offering of common stock,
subject to market conditions and to the Board's continuing to believe that
leveraging the Fund's capital structure through the issuance of preferred stock
is likely to achieve the benefits to the holders of common stock described in
the prospectus. Although the terms of the preferred stock, including its
dividend rate, voting rights, liquidation preference and redemption provisions
will be determined by the Board of Directors (subject to applicable law and the
Fund's Articles of Incorporation), the initial series of preferred stock will
be structured to carry either a relatively short-term dividend rate, in which
case periodic redetermination of the dividend rate will be made at relatively
short intervals (generally seven or 28 days), or a medium-term dividend rate,
in which case periodic redetermination of the dividend rate will be made at
intervals of up to five years. In either case, such redetermination of the
dividend rate will be made through an auction or remarketing procedure.
Additionally, under certain circumstances, when the Fund is required to
allocate taxable income to holders of the preferred stock, it is anticipated
that the terms of the preferred stock will require the Fund to make an
Additional Distribution (as defined in "Risks and Special Considerations of
Leverage--Effects of Leverage") to such holders. The Board also has indicated
that it is likely that the liquidation preference, voting rights and redemption
provisions of the preferred stock will be as stated below. The Fund's Articles
of Incorporation, as amended, together with any Articles Supplementary, is
referred to below as the "Charter."
 
  Liquidation Preference. In the event of any voluntary or involuntary
liquidation, dissolution or winding up of the Fund, the holders of shares of
preferred stock will be entitled to receive a preferential liquidating
distribution (expected to equal the original purchase price per share plus an
amount equal to accumulated and unpaid dividends whether or not earned or
declared and any accumulated and unpaid Additional Distribution) before any
distribution of assets is made to holders of common stock. After payment of the
full amount of the liquidating distribution to which they are entitled, the
preferred stockholders will not be entitled to any further
 
                                       38
<PAGE>
 
participation in any distribution of assets by the Fund. A consolidation or
merger of the Fund with or into any other corporation or corporations or a sale
of all or substantially all of the assets of the Fund will not be deemed to be
a liquidation, dissolution or winding up of the Fund.
 
  Voting Rights. Except as otherwise indicated in this prospectus and except as
otherwise required by applicable law, holders of shares of preferred stock will
have equal voting rights with holders of shares of common stock (one vote per
share) and will vote together with holders of common stock as a single class.
 
  In connection with the election of the Fund's directors, holders of shares of
preferred stock, voting as a separate class, will be entitled to elect two of
the Fund's directors, and the remaining directors will be elected by all
holders of capital stock, voting as a single class. So long as any preferred
stock is outstanding, the Fund will have not less than five directors. If at
any time dividends on shares of the Fund's preferred stock shall be unpaid in
an amount equal to two full years' dividends thereon, the holders of all
outstanding shares of preferred stock, voting as a separate class, will be
entitled to elect a majority of the Fund's directors until all dividends in
default have been paid or declared and set apart for payment.
 
  The affirmative vote of the holders of a majority of the outstanding shares
of the preferred stock, voting as a separate class, will be required to (i)
authorize, create or issue any class or series of stock ranking prior to any
series of preferred stock with respect to payment of dividends or the
distribution of assets on liquidation or (ii) amend, alter or repeal the
provisions of the Charter, whether by merger, consolidation or otherwise, so as
to adversely affect any of the contract rights expressly set forth in the
Charter of holders of preferred stock.
 
  Redemption Provisions. It is anticipated that shares of preferred stock will
generally be redeemable at the option of the Fund at a price equal to their
liquidation preference plus accumulated but unpaid dividends to the date of
redemption plus, under certain circumstances, a redemption premium. Shares of
preferred stock will also be subject to mandatory redemption at a price equal
to their liquidation preference plus accumulated but unpaid dividends to the
date of redemption upon the occurrence of certain specified events, such as the
failure of the Fund to maintain asset coverage requirements for the preferred
stock specified by the rating agencies that issue ratings on the preferred
stock.
 
Certain Provisions of the Articles of Incorporation
 
  The Fund's Articles of Incorporation include provisions that could have the
effect of limiting the ability of other entities or persons to acquire control
of the Fund or to change the composition of its Board of Directors and could
have the effect of depriving shareholders 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, but only by vote of the holders of at least 66
2/3% of the votes entitled to be voted on the matter. A director elected by all
the holders of capital stock may be removed only by action of such holders, and
a director elected by the holders of preferred stock may be removed only by
action of such holders.
 
  In addition, the Articles of Incorporation require the favorable vote of the
holders of at least 66 2/3% 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:
 
    .  a merger or consolidation or statutory share exchange of the Fund
       with other corporations,
 
                                       39
<PAGE>
 
    .  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
 
    .  a liquidation or dissolution of the Fund, unless such action has
       been approved, adopted or authorized by the affirmative vote of two-
       thirds of the total number of Directors fixed in accordance with the
       by-laws, in which case the affirmative vote of a majority of the
       Fund's shares of capital stock is required. Following the proposed
       issuance of the preferred stock, it is anticipated that the
       approval, adoption or authorization of the foregoing would also
       require the favorable vote of a majority of the Fund's shares of
       preferred stock then entitled to be voted, voting as a separate
       class.
 
  In addition, conversion of the 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 shareholders. Such an amendment would require the favorable vote
of the holders of at least 66 2/3% of the Fund's outstanding shares of capital
stock (including any 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 two-thirds of the total number of
Directors fixed in accordance with the by-laws), and, assuming preferred stock
is issued, the affirmative vote of a majority of outstanding shares of
preferred stock of the Fund, voting as a separate class. Such a vote also would
satisfy a separate requirement in the 1940 Act that the change be approved by
the shareholders. Shareholders of an open-end investment company may require
the company to redeem their shares of common stock at any time (except in
certain circumstances as authorized by or under the 1940 Act) at their net
asset value, less such redemption charge, if any, as might be in effect at the
time of a redemption. All redemptions will be made in cash. If the Fund is
converted to an open-end investment company, it could be required to liquidate
portfolio securities to meet requests for redemption, and the common stock
would no longer be listed on a stock exchange.
 
  Conversion to an open-end investment company would also require redemption of
all outstanding shares of preferred stock 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 has determined that the 66 2/3% voting requirements
described above, which are greater than the minimum requirements under Maryland
law or the 1940 Act, are in the best interests of shareholders generally.
Reference should be made to the Charter on file with the Securities and
Exchange Commission for the full text of these provisions.
 
                                   CUSTODIAN
   
  The Fund's securities and cash are held under a custodial agreement with The
Bank of New York, 90 Washington Street, New York, NY 10286.

                                  UNDERWRITING
   
  Merrill Lynch, Pierce, Fenner & Smith Incorporated (the "Underwriter") has
agreed, subject to the terms and conditions of a Purchase Agreement with the
Fund and the Investment Adviser, to purchase 6,700,000 shares of common stock
from the Fund. The Underwriter is committed to purchase all of such shares if
any are purchased.     
   
  The Underwriter has advised the Fund that it proposes initially to offer the
shares of common stock to the public at the public offering price set forth on
the cover page of this prospectus. There is no sales charge or underwriting
discount charged to investors on purchases of shares of common stock in the
offering. The Investment Adviser or an affiliate has agreed to pay the
Underwriter from its own assets a commission in connection with the sale of
shares of common stock in the offering in the amount of $    per share. Such
payment is equal to     % of the initial public offering price per share. The
Underwriter also has advised the Fund that from this amount the Underwriter may
pay a concession to certain dealers not in excess of $    per share on sales by
such dealers. After the initial public offering, the public offering price and
other selling terms may be changed. Investors must pay for shares of common
stock purchased in the offering on or before May   , 1999.     
   
  The Fund has granted the Underwriter an option, exercisable for 45 days after
the date hereof, to purchase up to 1,005,000 additional shares of common stock
to cover over-allotments, if any, at the initial offering price.     
 
  The Underwriter may engage in certain transactions that stabilize the price
of the shares of common stock. Such transactions consist of bids or purchases
for the purpose of pegging, fixing or maintaining the price of the shares of
common stock.
 
  If the Underwriter creates a short position in the shares of common stock in
connection with the offering, i.e., if it sells more shares of common stock
than are set forth on the cover page of this prospectus, the Underwriter may
reduce that short position by purchasing shares of common stock in the open
market. The Underwriter also may elect to reduce any short position by
exercising all or part of the over-allotment option described above.
 
  The Underwriter also may impose a penalty bid on certain selling group
members. This means that if the Underwriter purchases shares of common stock in
the open market to reduce the Underwriter's short position or to stabilize the
price of the shares of common stock, it may reclaim the amount of the selling
concession from the selling group members who sold those shares of common stock
as part of the offering.
 
  In general, purchases of a security for the purpose of stabilization or to
reduce a short position could cause the price of the security to be higher than
it might be in the absence of such purchases. The imposition of a penalty bid
might also have an effect on the price of a security to the extent that it were
to discourage resales of the security.
 
  Neither the Fund nor the Underwriter makes any representation or prediction
as to the direction or magnitude of any effect that the transactions described
above may have on the price of the shares of common stock. In addition, neither
the Fund nor the Underwriter makes any representation that the Underwriter will
engage in such transactions or that such transactions, once commenced, will not
be discontinued without notice.
 
                                       41
<PAGE>
 
  Prior to this offering, there has been no public market for the shares of the
common stock. The Fund plans to apply to list its common stock on the NYSE or
another national securities exchange. However, during an initial period which
is not expected to exceed two weeks from the date of this prospectus, the
Fund's common stock will not be listed on any securities exchange.
Additionally, before it begins trading, the Underwriter does not intend to make
a market in the Fund's common stock, although a limited market may develop.
Thus, it is anticipated that investors may not be able to buy and sell shares
of the Fund during such period. In order to meet the requirements for listing,
the Underwriter has undertaken to sell lots of 100 or more shares to a minimum
of 2,000 beneficial owners.
 
  The Fund anticipates that the Underwriter may from time to time act as a
broker in connection with the execution of its portfolio transactions. The Fund
has obtained an exemptive order permitting it to engage in certain principal
transactions with the Underwriter involving high quality, short-term, tax-
exempt securities subject to certain conditions. See "Investment Restrictions"
and "Portfolio Transactions."
 
  The Underwriter is an affiliate of the Investment Adviser of the Fund.
 
  The Fund and the Investment Adviser have agreed to indemnify the Underwriter
against certain liabilities, including liabilities under the Securities Act of
1933.
 
            TRANSFER AGENT, DIVIDEND DISBURSING AGENT AND REGISTRAR
   
  The transfer agent, dividend disbursing agent and registrar for the shares of
common stock of the Fund is The Bank of New York, 101 Barclay Street, New York,
NY 10286.     
 
                                 LEGAL OPINIONS
 
  Certain legal matters in connection with the common stock offered hereby will
be passed upon for the Fund and the Underwriter by Brown & Wood LLP, New York,
New York.

Year 2000 Issues
 
  Many computer systems were designed using only two digits to designate years.
These systems may not be able to distinguish the Year 2000 from the Year 1900
(commonly known as the "Year 2000 Problem"). The Fund could be adversely
affected if the computer systems used by the Investment Adviser or other Fund
service providers do not properly address this problem before January 1, 2000.
The Investment Adviser expects to have addressed this problem before then, and
does not anticipate that the services it provides will be adversely affected.
The Fund's other service providers have told the Investment Adviser that they
also expect to resolve the Year 2000 Problem, and the Investment Adviser will
continue to monitor the situation as the Year 2000 approaches. However, if the
problem has not been fully addressed, the Fund could be negatively affected.
The Year 2000 Problem could also have a negative impact on the issuers of
securities in which the Fund invests, and this could hurt the Fund's investment
returns.

                           RATINGS OF MUNICIPAL BONDS
 
Description of Moody's Investors Service, Inc.'s ("Moody's") Municipal Bond
Ratings
 
Aaa  Bonds which are rated Aaa are judged to be of the best quality. They
     carry the smallest degree of investment risk and are generally
     referred to as "gilt edge." Interest payments are protected by a large
     or by an exceptionally stable margin and principal is secure. While
     the various protective elements are likely to change, such changes as
     can be visualized are most unlikely to impair the fundamentally strong
     position of such issues.
 
Aa   Bonds which are rated Aa are judged to be of high quality by all
     standards. Together with the Aaa group they comprise what are
     generally known as high grade bonds. They are rated lower than the
     best bonds because margins of protection may not be as large as in Aaa
     securities or fluctuation of protective elements may be of greater
     amplitude or there may be other elements present which make the long-
     term risks appear somewhat larger than in Aaa securities.
 
A    Bonds which are rated A possess many favorable investment attributes
     and are to be considered as upper medium grade obligations. Factors
     giving security to principal and interest are considered adequate, but
     elements may be present which suggest a susceptibility to impairment
     sometime in the future.
 
Baa  Bonds which are rated Baa are considered as medium grade obligations,
     i.e., they are neither highly protected nor poorly secured. Interest
     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.
 
  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.
 
                                       46
<PAGE>
 
  Short-term Notes: The three ratings of Moody's for short-term notes are MIG
1/VMIG 1, MIG 2/VMIG 2, and MIG 3/VMIG 3; 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".
 
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 supporting institutions) have a superior ability
for repayment of short-term promissory obligations. Prime-1 repayment ability
will often be evidenced by many of the following characteristics: leading
market positions in well established industries; high rates of return on funds
employed; conservative capitalization structures with moderate reliance on debt
and ample asset protection; broad margins in earning coverage of fixed
financial charges and high internal cash generation; and well established
access to a range of financial markets and assured sources of alternate
liquidity.
 
  Issuers rated Prime-2 (or supporting institutions) have a strong ability for
repayment of short-term promissory obligations. This will normally be evidenced
by many of the characteristics cited above but to a lesser degree. Earnings
trends and coverage ratios, while sound, may be more subject to variation.
Capitalization characteristics, while still appropriate, may be more affected
by external conditions. Ample alternate liquidity is maintained.
 
  Issuers rated Prime-3 (or supporting institutions) have an acceptable ability
for repayment of short-term promissory obligations. The effects of industry
characteristics and market composition may be more pronounced. Variability in
earnings and profitability may result in changes to the level of debt
protection measurements and may require relatively high financial leverage.
Adequate alternate liquidity is maintained.
 
  Issuers rated Not Prime do not fall within any of the Prime rating
categories.
 
Description of Standard & Poor's, a Division of The McGraw-Hill Companies, Inc.
("Standard & Poor's"), Municipal Debt Ratings
 
  A Standard & Poor's municipal debt rating is a current opinion of the
creditworthiness of an obligor with respect to a specific financial obligation,
a specific class of financial obligations or a specific program. It takes into
consideration the creditworthiness of guarantors, insurers, or other forms of
credit enhancement on the obligation.
 
  The debt rating is not a recommendation to purchase, sell or hold a financial
obligation, inasmuch as it does not comment as to market price or suitability
for a particular investor.
 
  The ratings are based on current information furnished by the obligors or
obtained by Standard & Poor's from other sources 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 based on circumstances.
 
                                       47
<PAGE>
 
  The ratings are based, in varying degrees, on the following considerations:
 
    I. Likelihood of payment--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 meet its financial commitment on the obligation is
     extremely strong.
 
AA   Debt rated "AA" differs from the highest rated issues only in small
     degree. The Obligor's capacity to meet its financial commitment on the
     obligation is very strong.
 
A    Debt rated "A" is somewhat more susceptible to the adverse effects of
     changes in circumstances and economic conditions than debt in higher-
     rated categories. However, the obligor's capacity to meet its
     financial commitment on the obligation is still strong.
 
BBB  Debt rated "BBB" exhibits adequate protection parameters. However,
     adverse economic conditions or changing circumstances are more likely
     to lead to a weakened capacity of the obligor to meet its financial
     commitment on the obligation.
 
BB   Debt rated "BB," "B," "CCC," "CC" and "C" are regarded as having
B    significant speculative characteristics. "BB" indicates the least
CCC  degree of speculation and "C" the highest degree of speculation. While
CC   such debt will likely have some quality and protective
C    characteristics, these may be outweighed by large uncertainties or
     major risk exposures to adverse conditions.
 
D    Debt rated "D" is in payment default. The "D" rating category is used
     when payments on an obligation are not made on the date due even if
     the applicable grace period has not expired, unless Standard & Poor's
     believes that such payments will be made during such grace period. The
     "D" rating also will be used upon the filing of a bankruptcy petition
     or the taking of similar action if payments on an obligation are
     jeopardized.
 
  Plus (+) or Minus (-): The ratings from "AA" to "CCC" may be modified by the
addition of a plus or minus sign to show relative standing within the major
rating categories.
 
Description of Standard & Poor's Commercial Paper Ratings
 
  A Standard & Poor's commercial paper rating is a current assessment of the
likelihood of timely payment of debt having an original maturity of no more
than 365 days. Ratings are graded into several categories, ranging from "A-1"
for the highest-quality obligations to "D" for the lowest. These categories are
as follows:
 
A-1  This designation indicates that the degree of safety regarding timely
     payment is strong. Those issues determined to possess extremely strong
     safety characteristics are denoted with a plus sign (+) designation.
 
A-2  Capacity for timely payment on issues with this designation is
     satisfactory. However, the relative degree of safety is not as high as
     for issues designated "A-1."
 
                                       48
<PAGE>
 
A-3  Issues carrying this designation have an adequate capacity for timely
     payment. They are, however, more vulnerable to the adverse effects of
     changes in circumstances than obligations carrying the higher
     designations.
 
B    Issues rated "B" are regarded as having only speculative capacity for
     timely payment.
 
C    This rating is assigned to short-term debt obligations with a doubtful
     capacity for payment.
 
D    Debt rated "D" is in payment default. The "D" rating category is used
     when interest payments or principal payments are not made on the date
     due, even if the applicable grace period has not expired unless
     Standard & Poor's believes that such payments will be made during such
     grace period.
 
  A commercial paper rating is not a recommendation to purchase or sell a
security. The ratings are based on current information furnished to Standard &
Poor's by the issuer or obtained by Standard & Poor's from other sources it
considers reliable. The ratings may be changed, suspended, or withdrawn as a
result of changes in, or unavailability of, such information.
 
  A Standard & Poor's note rating reflects the liquidity factors and market
access risks unique to notes. Notes due in three years or less will likely
receive a note rating. Notes maturing beyond three years will most likely
receive a long-term debt rating. The following criteria will be used in making
that assessment.
 
  --Amortization schedule--the larger the final maturity relative to other
   maturities, the more likely it will be treated as a note.
 
  --Source of payment--the more dependent the issue is on the market for its
   refinancing, the more likely it will be treated as a note.
 
  Note rating symbols are as follows:
 
SP-1  Strong capacity to pay principal and interest. An issue determined to
      possess a very strong capacity to pay debt service is given a plus (+)
      designation.
 
SP-2  Satisfactory capacity to pay principal and interest with some
      vulnerability to adverse financial and economic changes over the term of
      the notes.
 
SP-3  Speculative capacity to pay principal and interest.
 
Description of Fitch IBCA, 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.
 
 
                                      49
<PAGE>
 
  Bonds carrying the same rating are of similar but not necessarily identical
credit quality since the rating categories do not fully reflect small
differences in the degrees of credit risk.
 
  Fitch ratings are not recommendations to buy, sell, or hold any security.
Ratings do not comment on the adequacy of market price, the suitability of any
security for a particular investor, or the tax-exempt nature or taxability of
payments made in respect of any security.
 
  Fitch ratings are based on information obtained from issuers, other obligors,
underwriters, their experts, and other sources Fitch believes to be reliable.
Fitch does not audit or verify the truth or accuracy of such information.
Ratings may be changed, suspended, or withdrawn as a result of changes in, or
the unavailability of, information or for other reasons.
 
AAA Bonds considered to be investment grade and of the highest credit
    quality. The obligor has an exceptionally strong ability to pay
    interest and repay principal, which is unlikely to be affected by
    reasonably foreseeable events.
 
AA  Bonds considered to be investment grade and of very high credit
    quality. The obligor's ability to pay interest and repay principal is
    very strong, although not quite as strong as bonds rated "AAA." Because
    bonds rated in the "AAA" and "AA" categories are not significantly
    vulnerable to foreseeable future developments, short-term debt of these
    issuers is generally rated "F-1+."
 
A   Bonds considered to be investment grade and of high credit quality. The
    obligor's ability to pay interest and repay principal is considered to
    be strong, but may be more vulnerable to adverse changes in economic
    conditions and circumstances than bonds with higher ratings.
 
BBB Bonds considered to be investment grade and of satisfactory-credit
    quality. The obligor's ability to pay interest and repay principal is
    considered to be adequate. Adverse changes in economic conditions and
    circumstances, however, are more likely to have adverse impact on these
    bonds, and therefore impair timely payment. The likelihood that the
    ratings of these bonds will fall below investment grade is higher than
    for bonds with higher ratings.
 
  Plus (+) or Minus (-): Plus and minus signs are used with a rating symbol to
indicate the relative position of a credit within the rating category. Plus and
minus signs, however, are not used in the "AAA" category.
 
NR           Indicates that Fitch does not rate the specific issue.
 
Conditional  A conditional rating is premised on the successful completion of
             a project or the occurrence of a specific event.
 
Suspended    A rating is suspended when Fitch deems the amount of information
             available from the issuer to be inadequate for rating purposes.
 
Withdrawn    A rating will be withdrawn when an issue matures or is called or
             refinanced and, at Fitch's discretion, when an issuer fails to
             furnish proper and timely information.

FitchAlert   Ratings are placed on FitchAlert to notify investors of an
             occurrence that is likely to result in a rating change and the
             likely direction of such change. These are designated as
             "Positive," indicating a potential upgrade, "Negative," for
             potential downgrade, or "Evolving," where ratings may be raised
             or lowered. FitchAlert is relatively short-term, and should be
             resolved within 12 months.
 
  Ratings Outlook: An outlook is used to describe the most likely direction of
any rating change over the intermediate term. It is described as "Positive" or
"Negative." The absence of a designation indicates a stable outlook.
 
Description of Fitch'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 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 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.
 
 
                                       51
<PAGE>
 
  Plus (+) or Minus (-): Plus and minus signs are used with a rating symbol to
indicate the relative position of a credit within the rating category. Plus and
minus signs, however, are not used in the "DDD," "DD," or "D" categories.
 
Description of Fitch's Short-Term Ratings
 
  Fitch's short-term ratings apply to debt obligations that are payable on
demand or have original maturities of up to three years, including commercial
paper, certificates of deposit, medium-term notes, and municipal and investment
notes.
 
  The short-term rating places greater emphasis than a long-term rating on the
existence of liquidity necessary to meet the issuer's obligations in a timely
manner.
 
  Fitch short-term ratings are as follows:
 
F-1+         Exceptionally Strong Credit Quality. Issues assigned this rating
             are regarded as having the strongest degree of assurance for
             timely payment.
 
F-1          Very Strong Credit Quality. Issues assigned this rating reflect
             an assurance of timely payment only slightly less in degree than
             issues rated "F-1+."
 
F-2          Good Credit Quality. Issues assigned this rating have a
             satisfactory degree of assurance for timely payment, but the
             margin of safety is not as great as for issues assigned "F-1+"
             and "F-1" ratings.
 
F-3          Fair Credit Quality. Issues assigned this rating have
             characteristics suggesting that the degree of assurance for
             timely payment is adequate; however, near-term adverse changes
             could cause these securities to be rated below investment grade.
 
F-S          Weak Credit Quality. Issues assigned this rating have
             characteristics suggesting a minimal degree of assurance for
             timely payment and are vulnerable to near-term adverse changes in
             financial and economic conditions.
 
D            Default. Issues assigned this rating are in actual or imminent
             payment default.
 
LOC          The symbol "LOC" indicates that the rating is based on a letter
             of credit issued by a commercial bank.

                                  APPENDIX II
 
                              PORTFOLIO INSURANCE
 
  Set forth below is further information with respect to the insurance policies
(the "Policies") that the Fund may obtain from several insurance companies with
respect to insured Municipal Bonds held by the Fund. The Fund has no obligation
to obtain any such Policies, and the terms of any Policies actually obtained
may vary significantly from the terms discussed below.
 
  In determining eligibility for insurance, insurance companies will apply
their own standards. These standards correspond generally to the standards such
companies normally use in establishing the insurability of new issues of
Municipal Bonds and are not necessarily the criteria that would be used in
regard to the purchase of such bonds by the Fund. The Policies do not insure
(i) municipal securities ineligible for insurance and (ii) municipal securities
no longer owned by the Fund.
 
  The Policies do not guarantee the market value of the insured Municipal Bonds
or the value of the shares of the Fund. 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 the Fund that is adversely affected by either of
the above described events. In addition to the payment of premiums, the
Policies may require that the 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 the 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 Fund will seek to utilize insurance companies that have insurance claims-
paying ability ratings of AAA from Standard & Poor's ("S&P") or Fitch IBCA,
Inc. ("Fitch") or Aaa from Moody's Investors Service ("Moody's"). There can be
no assurance however, that insurance from insurance carriers meeting these
criteria will be at all times available.
 
  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 considered by S&P to be extremely
strong and highly likely to remain so over a long period of time. 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, capitalization and liquidity are
all at very secure levels and are unlikely to be affected by potential adverse
underwriting, investment or cyclical events. 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 considered 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
 
                                       53
<PAGE>
 
these companies is likely to change, such changes as can be visualized are most
unlikely to impair the company's fundamentally strong position.
 
  An insurance claims-paying ability rating of S&P, Fitch or Moody's 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, Fitch or Moody's 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 27. Persons Controlled by or Under Common Control with Registrant.
 
  The information in the prospectus under the captions "Investment Advisory and
Management Arrangements" and "Description of Capital Stock--Common Stock" and
in Note 1 to the Statement of Assets, Liabilities and Capital is incorporated
herein by reference.
 
Item 28. Number of Holders of Securities.
 
  There will be one record holder of the Common Stock, par value $0.10 per
share, as of the effective date of this Registration Statement.
 
Item 29. Indemnification.
 
  Section 2-418 of the General Corporation Law of the State of Maryland,
Article VI of the Registrant's Articles of Incorporation, filed as Exhibit
(a)(1) to this Registration Statement, Article VI of the Registrant's By-Laws,
filed as Exhibit (b) to this Registration Statement, and the Investment
Advisory Agreement, a form of which is filed as Exhibit (g)(1) to this
Registration Statement, provide for indemnification.
 
  Insofar as indemnification for liabilities arising under the Securities Act
of 1933, as amended (the "1933 Act") may be provided to directors, officers and
controlling persons of the Fund, pursuant to the foregoing provisions or
otherwise, the Fund has been advised that in the opinion of the Securities and
Exchange Commission, such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the Fund of
expenses incurred or paid by a director, officer or controlling person of the
Fund 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 Fund will, unless in the
opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.
 
  Reference is made to Section Six of the Purchase Agreement, a form of which
is filed as Exhibit (h)(1) hereto, for provisions relating to the
indemnification of the underwriter.

                      MUNIHOLDINGS INSURED FUND III, INC.

                            TERMS AND CONDITIONS OF
                     AUTOMATIC DIVIDEND REINVESTMENT PLAN

     1.  Appointment of Agent.  You, __________, will act as Agent for me, and
         --------------------                                                 
will open an account for me under the Dividend Reinvestment Plan (the "Plan") in
the same name as my present shares of common stock, par value $.10 per share
("Common Stock"), of MUNIHOLDINGS INSURED FUND III, INC. (the "Fund") are
registered, and will automatically put into effect for me the dividend
reinvestment option of the Plan as of the first record date for a dividend or
capital gains distribution (collectively referred to herein as a "dividend"),
payable at the election of shareholders in cash or shares of Common Stock.

     2.  Dividends Payable in Common Stock.  My participation in the Plan
         ---------------------------------                               
constitutes an election by me to receive dividends in shares of Common Stock
whenever the Fund declares a dividend.  In such event, the dividend amount shall
automatically be made payable to me entirely in shares of Common Stock which
shall be acquired by the Agent for my account, depending upon the circumstances
described in paragraph 3, either (i) through receipt of additional shares of
unissued but authorized shares of Common Stock from the Fund ("newly-issued
shares") as described in paragraph 6 or (ii) by purchase of outstanding shares
of Common Stock on the open market ("open-market purchases") as described in
paragraph 7.

     3.  Determination of Whether Newly-Issued Shares or Open-Market Purchases.
         ---------------------------------------------------------------------  
If on the payment date for the dividend (the "valuation date"), the net asset
value per share of the Common Stock, as defined in paragraph 8, is equal to or
less than the market price per share of the Common Stock, as defined in
paragraph 8, plus estimated brokerage commissions (such condition being referred
to herein as "market premium"), the Agent shall invest the dividend amount in
newly-issued shares on my behalf as described in paragraph 6.  If on the
valuation date, the net asset value per share is greater than the market value
(such condition being referred to herein as "market discount"), the Agent shall
invest the dividend amount in shares acquired on my behalf in open-market
purchases as described in paragraph 7.

     4.  Purchase Period for Open-Market Purchases.  In the event of a market
         -----------------------------------------                           
discount on the valuation date, the Agent shall have until the last business day
before the next ex-dividend date with respect to the shares of Common Stock or
in no event more than 30 days after the valuation date (the "last purchase
date") to invest the dividend amount in shares acquired in open-market purchases
except where temporary curtailment or suspension of purchases is necessary to
comply with applicable provisions of federal securities laws.

     5.  Failure to Complete Open-Market Purchases During Purchase Period.  If
         ----------------------------------------------------------------     
the Agent is unable to invest the full dividend amount in open-market purchases
during the purchase period because the market discount has shifted to a market
premium or otherwise, the Agent will invest the uninvested portion of the
dividend amount in newly-issued shares at the close of business on the last
purchase date as described in paragraph 4; except that the Agent may not acquire
newly-issued shares after the valuation date under the foregoing circumstances
unless it has received a legal opinion that registration of such shares is not
required under the Securities Act of 1933, as amended, or unless the shares to
be issued are registered under such Act.
<PAGE>
 
     6.   Acquisition of Newly-Issued Shares.  In the event that all or part of
          ----------------------------------                                   
the dividend amount is to be invested in newly-issued shares, you shall
automatically receive such newly-issued shares of Common Stock, including
fractions, for my account, and the number of additional newly-issued shares of
Common Stock to be credited to my account shall be determined by dividing the
dollar amount of the dividend on my shares to be invested in newly-issued shares
by the net asset value per share of Common Stock on the date the shares are
issued (the valuation date in the case of an initial market premium or the last
purchase date in case the Agent is unable to complete open-market purchases
during the purchase period); provided, that the maximum discount from the then
current market price per share on the date of issuance shall not exceed 5%.

     7.   Manner of Making Open-Market Purchases. In the event that the dividend
          --------------------------------------  
amount is to be invested in shares of Common Stock acquired in open-market
purchases, you shall apply the amount of such dividend on my shares (less my pro
rata share of brokerage commissions incurred with respect to your open-market
purchases) to the purchase on the open-market of shares of the Common Stock for
my account.  Open-market purchases may be made on any securities exchange where
the Common Stock is traded, in the over-the-counter market or in negotiated
transactions and may be on such terms as to price, delivery and otherwise as you
shall determine.  My funds held by you uninvested will not bear interest, and it
is understood that, in any event, you shall have no liability in connection with
any inability to purchase shares within 30 days after the initial date of such
purchase as herein provided, or with the timing of any purchases affected.  You
shall have no responsibility as to the value of the Common Stock acquired for my
account.  For the purposes of cash investments you may commingle my funds with
those of other shareholders of the Fund for whom you similarly act as Agent, and
the average price (including brokerage commissions) of all shares purchased by
you as Agent in the open market shall be the price per share allocable to me in
connection with open-market purchases.

     8.   Meaning of Market Price and Net Asset Value.  For all purposes of the
          -------------------------------------------                          
Plan: (a) the market price of the Common Stock on a particular date shall be the
last sales price on the New York Stock Exchange (the "Exchange") on that date,
or, if there is no sale on the Exchange on that date, then the mean between the
closing bid and asked quotations for such stock on the Exchange on such date and
(b) net asset value per share of the Common Stock on a particular date shall be
as determined by or on behalf of the Fund.

     9.   Registration of Shares Acquired Pursuant to the Plan.  You may hold my
          ----------------------------------------------------                  
shares of Common Stock acquired pursuant to the Plan, together with the shares
of other shareholders of the Fund acquired pursuant to the Plan, in
noncertificated form in your name or that of your nominee.  You will forward to
me any proxy solicitation material and will vote any shares so held for me only
in accordance with the proxy returned by me to the Fund.  Upon my written
request, you will deliver to me, without charge, a certificate or certificates
for the full shares held by you for my account.

     10.  Confirmations.  You will confirm to me each acquisition made for my
          -------------                                                      
account as soon as practicable but not later than 60 days after the date
thereof.

                                       2
<PAGE>
 
     11.  Fractional Interests.  Although I may from time to time have an
          --------------------                                           
undivided fractional interest (computed to three decimal places) in a share of
the Fund, no certificates for a fractional share will be issued.  However,
dividends and distributions on fractional shares will be credited to my account.
In the event of termination of my account under the Plan, you will adjust for
any such undivided fractional interest in cash at the market value of the Fund's
shares at the time of termination less the pro rata expense of any sale required
to make such an adjustment.

     12.  Stock Dividends or Share Purchase Rights.  Any stock dividends or
          ----------------------------------------                         
split shares distributed by the Fund on shares held by you for me will be
credited to my account.  In the event that the Fund makes available to its
shareholders rights to purchase additional shares or other securities, the
shares held for me under the Plan will be added to other shares held by me in
calculating the number of rights to be issued to me.

     13.  Service Fee.  Your service fee for handling capital gains
          -----------                                              
distributions or income dividends will be paid by the Fund.  I will be charged
for my pro rata share of brokerage commissions on all open market purchases.

     14.  Termination of Account.  I may terminate my account under the Plan by
          ----------------------                                               
notifying you in writing.  Such termination will be effective immediately if my
notice is received by you not less than ten days prior to any dividend or
distribution record date; otherwise such termination will be effective on the
first trading day after the payment date for such dividend or distribution with
respect to any subsequent dividend or distribution.  The Plan may be terminated
by you or the Fund upon notice in writing mailed to me at least 90 days prior to
any record date for the payment of any dividend or distribution by the Fund.
Upon any termination you will cause a certificate or certificates for the full
shares held for me under the Plan and cash adjustment for any fraction to be
delivered to me without charge.  If I elect by notice to you in writing in
advance of such termination to have you sell part or all of my shares and remit
the proceeds to me, you are authorized to deduct brokerage commissions for this
transaction from the proceeds.

     15.  Amendment of Plan.  These terms and conditions may be amended or
          -----------------                                               
supplemented by you or the Fund at any time or times but, except when necessary
or appropriate to comply with applicable law or the rules or policies of the
Securities and Exchange Commission or any other regulatory authority, only by
mailing to me appropriate written notice at least 90 days prior to the effective
date thereof.  The amendment or supplement shall be deemed to be accepted by me
unless, prior to the effective date, thereof, you receive written notice of the
termination of my account under the Plan.  Any such amendment may include an
appointment by you in your place and stead of a successor Agent under these
terms and conditions, with full power and authority to perform all or any of the
acts to be performed by the Agent under these terms and conditions.  Upon any
such appointment of an Agent for the purpose of receiving dividends and
distributions, the Fund will be authorized to pay to such successor Agent, for
my account, all dividends and distributions payable on Common Stock of the Fund
held in my name or under the Plan for retention or application by such successor
Agent as provided in these terms and conditions.

                                       3
<PAGE>
 
     16.  Extent of Responsibility of Agent.  You shall at all times act in good
          ---------------------------------                                     
faith and agree to use your best efforts within reasonable limits to insure the
accuracy of all services performed under this Agreement and to comply with
applicable law, but assume no responsibility and shall not be liable for loss or
damage due to errors unless such error is caused by your negligence, bad faith,
or willful misconduct or that of your employees.

     17.  Governing Law.  These terms and conditions shall be governed by the
          -------------                                                      
laws of the State of New York without regard to its conflicts of laws
provisions.

                                  -----------

                    Compensation of the Investment Adviser
                    --------------------------------------

     (a)  Investment Advisory Fee.  For the services rendered, the facilities
          -----------------------                                            
furnished and the expenses assumed by the Investment Adviser, the Fund shall pay
to the Investment Adviser at the end of each calendar month a fee based upon the
average weekly value of the net assets of the Fund at the annual rate of 0.55 of
1.0% (0.55%) of the average weekly net assets of the Fund (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 shares of outstanding
preferred stock), commencing on the day following effectiveness hereof.  For
purposes of this calculation, average weekly net 

                                       5
<PAGE>
 
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. It is
understood that the liquidation preference of any outstanding preferred stock
(other than accumulated dividends) is not considered a liability in determining
the Fund's average weekly net assets. If this Agreement becomes effective
subsequent to the first day of a month or shall terminate before the last day of
a month, compensation for that part of the month this Agreement is in effect
shall be prorated in a manner consistent with the calculation of the fee as set
forth above. Subject to the provisions of subsection (b) hereof, payment of the
Investment Adviser's compensation for the preceding month shall be made as
promptly as possible after completion of the computations contemplated by
subsection (b) hereof. During any period when the determination of net asset
value is suspended by the Board of Directors, the average net asset value of a
share for the last week prior to such suspension shall for this purpose shall be
deemed to be the net asset value at the close of each succeeding week until it
is again determined.

     (b)  Expense Limitations.  In the event the operating expenses of the Fund,
          -------------------                                                   
including amounts payable to the Investment Adviser pursuant to subsection (a)
hereof, for any fiscal year ending on a date on which this Agreement is in
effect exceed the expense limitations applicable to the Fund imposed by
applicable state securities laws or regulations thereunder, as such limitations
may be raised or lowered from time to time, the Investment Adviser shall reduce
its management and investment advisory fee by the extent of such excess and, if
required pursuant to any such laws or regulations, will reimburse the Fund in
the amount of such excess; provided, however, to the extent permitted by law,
                           --------  -------                                 
there shall be excluded from such expenses the amount of any interest, taxes,
distribution fees, brokerage fees and commissions and extraordinary 

                                       6
<PAGE>
 
expenses (including but not limited to legal claims and liabilities and
litigation costs and any indemnification related thereto) paid or payable by the
Fund. Whenever the expenses of the Fund exceed a pro rata portion of the
applicable annual expense limitations, the estimated amount of reimbursement
under such limitations shall be applicable as an offset against the monthly
payment of the fee due to the Investment Adviser. Should two or more such
expense limitations be applicable as at the end of the last business day of the
month, that expense limitation which results in the largest reduction in the
Investment Adviser's fee shall be applicable.

                                  ARTICLE IV
                                  ----------

               Limitation of Liability of the Investment Adviser
               -------------------------------------------------

     The Investment Adviser shall not be liable for any error of judgment or
mistake of law or for any loss arising out of any investment or for any act or
omission in the management of the Fund, except for willful misfeasance, bad
faith or gross negligence in the performance of its duties, or by reason of
reckless disregard of its obligations and duties hereunder.  As used in this
Article IV, the term "Investment Adviser" shall include any affiliates of the
Investment Adviser performing services for the Fund contemplated hereby and
directors, officers and employees of the Investment Adviser and of such
affiliates.

                                   ARTICLE V
                                   ---------

                     Activities of the Investment Adviser
                     ------------------------------------

     The services of the Investment Adviser to the Fund are not to be deemed to

                  Duration and Termination of this Agreement
                  ------------------------------------------

     This Agreement shall become effective as of the date first above written
and shall remain in force until             , 2001, and thereafter, but only so

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

                         Definitions of Certain Terms

Merrill Lynch, Pierce, Fenner & Smith
                Incorporated
North Tower
World Financial Center
New York, New York  10281-1201

Ladies and Gentlemen:

     MuniHoldings Insured Fund III, Inc., a Maryland corporation (the "Fund"),
and Fund Asset Management, L.P., a Delaware limited partnership (the "Adviser"),
each confirms its agreement with Merrill Lynch & Co., Merrill Lynch, Pierce,
Fenner & Smith Incorporated (the "Underwriter"), with respect to the issue and
sale by the Fund and the purchase by the Underwriter of _______ shares of common
stock, par value $.10 per share, of the Fund (the "Common Stock"), and, with
respect to the grant by the Fund to the Underwriter of the option described in
Section 2(b) hereof to purchase all or any part of ________ additional shares of
Common Stock to cover over-allotments, if any. The aforesaid ____________ shares
of Common Stock (the "Initial Shares") to be purchased by the Underwriter and
all or any part of the ____________ shares of Common Stock subject to the option
described in Section 2(b) hereof (the "Option Shares"), are hereinafter called,
collectively, the "Shares."

     The Fund understands that the Underwriter proposes to make a public
offering of the Shares as soon as the Underwriter deems advisable after this
Agreement has been executed and delivered.

     The Fund has filed with the Securities and Exchange Commission (the
"Commission") a notification on Form N-8A of registration of the Fund as an
investment company under the Investment Company Act of 1940, as amended (the
"Investment Company Act"), and a registration statement on Form N-2 (No. 333- ),
including the related preliminary prospectus, for the registration of the Shares
under the Securities Act of 1933, as amended (the "1933 Act"), the Investment
Company Act, and the rules and regulations of the Commission under the 1933 Act
and the Investment Company Act (together, the "Rules and Regulations"), and has
filed such amendments to such registration statement on Form N-2, if any, and
such amended preliminary 
<PAGE>
 
prospectuses as may have been required to the date hereof. Promptly after
execution and delivery of this Agreement, the Fund will either (i) prepare and
file a prospectus in accordance with the provisions of paragraph (c) of Rule 497
("Rule 497(c)") of the rules and regulations of the Commission under the 1933
Act (the "1933 Act Regulations") or a certificate in accordance with the
provisions of paragraph (j) of Rule 497 ("Rule 497(j)") of the 1933 Act
Regulations, (ii) prepare and file a prospectus in accordance with the
provisions of Rule 430A ("Rule 430A") of the 1933 Act Regulations and paragraph
(h) of Rule 497 ("Rule 497(h)") of the 1933 Act Regulations, or (iii) if the
Fund has elected to rely upon Rule 434 ("Rule 434") of the 1933 Act Regulations,
prepare and file a term sheet (a "Term Sheet") in accordance with the provisions
of Rule 434 and Rule 497(h). The information included in any such prospectus or
in any such Term Sheet, as the case may be, that was omitted from such
registration statement at the time it became effective but that is deemed to be
part of such registration statement at the time it became effective (a) pursuant
to paragraph (b) of Rule 430A is referred to as "Rule 430A Information" or (b)
pursuant to paragraph (d) of Rule 434 is referred to as "Rule 434 Information."
Each prospectus used before such registration statement became effective, and
any prospectus that omitted, as applicable, the Rule 430A Information or the
Rule 434 Information, that was used after such effectiveness and prior to the
execution and delivery of this Agreement, is herein called a "preliminary
prospectus." Such registration statement, including the exhibits thereto and
schedules thereto, if any, at the time it became effective and including the
Rule 430A Information and the Rule 434 Information, as applicable, is herein
called the "Registration Statement." Any registration statement filed pursuant
to Rule 462(b) of the 1933 Act Regulations is herein referred to as the "Rule
462(b) Registration Statement," and after such filing the term "Registration
Statement" shall include the Rule 462(b) Registration Statement. The final
prospectus in the form first furnished to the Underwriter for use in connection
with the offering of the Shares is herein called the "Prospectus." If Rule 434
is relied on, the term "Prospectus" shall refer to the preliminary prospectus
dated __________, 1999, together with the applicable Term Sheet and all
references in this Agreement to the date of such Prospectus shall mean the date
of the applicable Term Sheet. For purposes of this Agreement, all references to
the Registration Statement, any preliminary prospectus, the Prospectus, or any
Term Sheet or any amendment or supplement to any of the foregoing shall be
deemed to include the copy filed with the Commission pursuant to its Electronic
Data Gathering, Analysis and Retrieval system ("EDGAR").

     All references in this Agreement to financial statements and schedules and
other information which is "contained," "included" or "stated" in the
Registration Statement, any preliminary prospectus or the Prospectus (or other
references of like import) shall be deemed to mean and include all such
financial statements and schedules and other information which is incorporated
by reference in the Registration Statement, any preliminary prospectus or the
Prospectus, as the case may be.

     Statement has been issued under the 1933 Act and no proceedings for that
     purpose have been instituted or are pending or, to the knowledge of the
     Fund, are contemplated by the Commission, and any request on the part of
     the Commission for additional information has been complied with. If
     required, the Fund has received any orders exempting the Fund from any

     Registration Statement and any post-effective amendments thereto became

     to state a material fact necessary in order to make the statements therein,
     in the light of the circumstances under which they were made, not
     misleading. The representations and warranties in this subsection shall not
     apply to statements in or omissions from the Registration Statement or the
     Prospectus made in reliance upon and in conformity with information
     furnished to the Fund in writing by the Underwriter expressly for use in
     the Registration Statement or in the Prospectus. If Rule 434 is used, the
     Fund will comply with the requirements of Rule 434.

          Each preliminary prospectus and the prospectus filed as part of the
     Registration Statement as originally filed or as part of any amendment
     thereto, or filed pursuant to Rule 497(c) or Rule 497(h) under the 1933

     which infringement or conflict (if the subject of any unfavorable decision,
     ruling or finding) or invalidity or inadequacy, singly or in the aggregate,

     the business now operated by it; the Fund is in compliance with the terms
     and conditions of all such Governmental Licenses, except where the failure
     so to comply would not, singly or in the aggregate, have a Material Adverse
     Effect; all of the Governmental Licenses are valid and in full force and
     effect, except when the invalidity of such Governmental Licenses or the
     failure of such Governmental Licenses to be in full force and effect would
     not have a Material Adverse Effect; and the Fund has not received any
     notice of proceedings relating to the revocation or modification of any
     such Governmental Licenses which, singly or in the aggregate, if the
     subject of an unfavorable decision, ruling or finding, would result in a
     Material Adverse Effect.

Rule 434, as applicable, and will notify the Underwriter immediately, and
confirm the notice in writing, (i) if any post-effective amendment to the

Commission of any stop order suspending the effectiveness of the Registration
Statement or of any order preventing or suspending the use of any preliminary
prospectus, or of the suspension of the qualification of the Shares for offering
or sale in any jurisdiction, or of the initiation or threatening of any
proceedings for any of such purposes, and (v) of the issuance by the Commission
of an order of suspension or revocation of the notification on Form N-8A of
registration of the Fund as an investment company under the Investment Company
Act or the initiation of any proceeding for that purpose. The Fund will make
every reasonable effort to prevent the issuance of any stop order described in
subsection (iv) hereunder or any order of suspension or revocation described in
subsection (v) hereunder and, if any such stop order or order of suspension or
revocation is issued, to obtain the lifting thereof at the earliest possible
moment. The Fund will promptly effect the filings necessary pursuant to Rule
497(c), Rule 497(j) or Rule 497(h) and will take such steps as it deems
necessary to ascertain promptly whether the certificate transmitted for filing
under Rule 497(j) or the form of prospectus transmitted for filing under Rule
497(c) or Rule 497(h) was received for filing by the Commission and, in the
event that it was not, it will promptly file such certificate or prospectus. 

     (b)  Filing of Amendments. The Fund will give the Underwriter notice of its
intention to file or prepare any amendment to the Registration Statement
(including any post-effective amendment or filing under Rule 462(b)), any Term
Sheet or any amendment, supplement or revision to either the prospectus included
in the Registration Statement at the time it became effective or to the
Prospectus, whether pursuant to the Investment Company Act, the 1933 Act, or
otherwise, and will furnish the Underwriter with copies of any such documents a
reasonable amount of time prior to such proposed filing or use, as the case may
be, and will not file or use any such document to which the Underwriter or
counsel to the Underwriter and the Fund shall object.

     (c)  Delivery of Registration Statements. The Fund has furnished or will
deliver to the Underwriter and counsel to the Underwriter and the Fund, without
charge, signed copies of the notification of registration on Form N-8A and
Registration Statement as originally filed and of each amendment thereto,
(including exhibits filed therewith, or incorporated by reference therein) and
signed copies of all consents and certificates of experts, and will also deliver
to the Underwriter a conformed copy, without charge, of the Registration
Statement as originally filed and of each amendment thereto (without exhibits)
for the Underwriter. The copies of the Registration Statement and each amendment
thereto furnished to the Underwriter will be identical to the electronically

permit the completion of the distribution of the Shares as contemplated in this
Agreement and in the Prospectus. If at any time when a prospectus is required by
the 1933 Act to be delivered in connection with sales of the Shares, any event
shall occur or condition shall exist as a result of which it is necessary, in
the opinion of counsel to the Underwriter and the Fund, to amend the
Registration Statement or amend or supplement any Prospectus in order that the
Prospectus will not include any untrue statements of material fact or omit to
state a material fact necessary in order to make the statements therein not
misleading in the light of the circumstances existing at the time it is
delivered to a purchaser, or if it shall be necessary, in the opinion of such
counsel, at any such time to amend the Registration Statement or amend or
supplement any Prospectus in order to comply with the requirements of the 1933
Act or the 1933 Act Regulations, the Fund will promptly prepare and file with
the Commission, subject to Section 3(b), such amendment or supplement as may be
necessary to correct such statement or omission or to make the Registration
Statement or the Prospectus comply with such requirements, and the Fund will
furnish to the Underwriter such number of copies of such amendment or supplement
as the Underwriter may reasonably request.

     (f)  Blue Sky Qualifications. The Fund will use its best efforts, in
cooperation with the Underwriter, to qualify the Shares for offering and sale
under the applicable securities laws of such states and other jurisdictions as
the Underwriter may designate and to maintain such qualifications in effect for
a period of not less than one year from the later of the effective date of the
Registration Statement and any Rule 462(b) Registration Statement; provided,
however, that the Fund shall not be obligated to file any general consent to
service of process or to qualify as a foreign corporation or as a dealer in
securities in any jurisdiction in which it is not so qualified or to subject
itself to taxation in respect of doing business in any jurisdiction in which it
is not otherwise so subject. In each jurisdiction in which the Shares have been
so qualified, the Fund will file such statements and reports as may be required
by the laws of such jurisdiction to continue such qualification in effect for a
period of not less than one year from the effective date of the Registration
Statement and any Rule 462(b) Registration Statement.

     (g)  Rule 158. The Fund will timely file such reports pursuant to the
Investment Company Act as are necessary in order to make generally available to
its securityholders as soon as practicable an earnings statement for the
purposes of, and to provide the benefits contemplated by, the last paragraph of
Section 11(a) of the 1933 Act.

respect to any of the foregoing or (ii) enter into any swap or any other
agreement or any transaction that transfers, in whole or in part, directly or

otherwise. The foregoing sentence shall not apply to (A) the Shares to be sold
hereunder or (B) any shares or Common Stock issued pursuant to any dividend
reinvestment plan.

indemnifying party shall not (except with the consent of the indemnified party)
also be counsel to the indemnified party. In no event shall the indemnifying
parties be liable for the fees and expenses of more than one counsel (in
addition to any local counsel) separate from their own counsel for all
indemnified parties in connection with any one action or separate but similar or
related actions in the same jurisdiction arising out of the same general
allegations or circumstances. No indemnifying party shall, without the prior
written consent of the indemnified parties, settle or compromise or consent to
the entry of any judgment with respect to any litigation, or any investigation
or proceeding by any governmental agency or body, commenced or threatened, or
any claim whatsoever in respect of which indemnification or contribution could
be sought under this Section 6 or Section 7 hereof (whether or not the
indemnified parties are actual or potential parties thereto), unless such
settlement, compromise or consent (i) includes an unconditional release of each
indemnified party from all liability arising out of such litigation,
investigation, proceeding or claim and (ii) does not include a statement as to
or an admission of fault, culpability or a failure to act by or on behalf of any
indemnified party.

     (d)  Settlement without Consent if Failure to Reimburse. If at any time an
indemnified party shall have requested an indemnifying party to reimburse the
indemnified party for fees and expenses of counsel, such indemnifying party
agrees that it shall be liable for any settlement of the nature contemplated by
Section 6 (a)(ii) effected without its written consent if (i) such settlement is
entered into more than 45 days after receipt by such indemnifying party of the
aforesaid request, (ii) such indemnifying party shall have received notice of
the terms of such settlement at least 30 days prior to such settlement being
entered into and (iii) such indemnifying party shall not have reimbursed such
indemnified party in accordance with such request prior to the date of such
settlement.

     SECTION 7.   Contribution. If the indemnification provided for in Section 6
                  ------------
hereof is for any reason unavailable to or insufficient to hold harmless an
indemnified party in respect of any losses, liabilities, claims, damages or
expenses referred to therein, then each indemnifying party shall contribute to
the aggregate amount of such losses, liabilities, claims, damages and expenses
incurred by such indemnified party, as incurred, (i) in such proportion as is
appropriate to reflect the relative benefits received by the Fund and the
Adviser on the one hand and the Underwriter on the other hand from the offering
of the Shares pursuant to this Agreement or (ii) if the allocation provided by
clause (i) is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause (i)
above but also the relative fault of the Fund and the Adviser on the one hand
and of the Underwriter on the other hand in connection with the statements or
omissions which resulted in such losses, liabilities, claims, damages or
expenses, as well as any other relevant equitable considerations.

     The relative benefits received by the Fund and the Adviser on the one hand
and the Underwriter on the other hand in connection with the offering of the
Shares pursuant to this Agreement shall be deemed to be in the same respective
proportions as the total net proceeds from the offering of the Shares pursuant
to this Agreement (before deducting expenses) received by the Fund, and the
total underwriting commission received by the Underwriter, in each case as set
forth or otherwise indicated on the cover of the Prospectus, or, if Rule 434 is
used, the corresponding location on the Term Sheet, bear to the sum of the
aggregate initial public offering price of the Shares and the total underwriting
commission received by the Underwriter as set forth or otherwise indicated on
such cover.

     The relative fault of the Fund and the Adviser on the one hand and the
Underwriter on the other hand shall be determined by reference to, among other
things, whether any such untrue or alleged untrue statement of a material fact
or omission or alleged omission to state a material fact relates to information
supplied by the Fund and the Adviser or by the Underwriter and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission.

     The Fund, the Adviser and the Underwriter agree that it would not be just
and equitable if contribution pursuant to this Section 7 were determined by pro
rata allocation or by any other method of allocation which does not take account
of the equitable considerations referred to above in this Section 7. The
aggregate amount of losses, liabilities, claims, damages and expenses incurred
by an indemnified party and referred to above in this Section 7 shall be deemed
to include any legal or other expenses reasonably incurred by such indemnified
party in investigating, preparing or defending against any litigation, or any
investigation or proceeding by any governmental agency or body, commenced or
threatened, or any claim whatsoever based upon any such untrue or alleged untrue
statement or omission or alleged omission.

     Notwithstanding the provisions of this Section 7, the Underwriter shall not
be required to contribute any amount in excess of the amount by which the total
price at which the Shares underwritten by it and distributed to the public were
offered to the public exceeds the amount of any damages which the Underwriter
has otherwise been required to pay by reason of any such untrue or alleged
untrue statement or omission or alleged omission.

     No person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the 1933 Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

     For purposes of this Section 7, each person, if any, who controls the
Underwriter within the meaning of Section 15 of the 1933 Act shall have the same
rights to contribution as the Underwriter, and each director of the Fund and the
Adviser, respectively, each officer of the Fund who signed the Registration
Statement and each person, if any, who controls the Fund and the Adviser within
the meaning of Section 15 of the 1933 Act, shall have the same rights to
contribution as the Fund and the Adviser.

     SECTION 8.   Representations, Warranties and Agreements to Survive 
                  -----------------------------------------------------
Delivery.  All representations, warranties and agreements contained in this
- --------
Agreement or in certificates of officers of the Fund or of the Adviser submitted
pursuant hereto, shall remain operative and in full force and effect, regardless

person, or by or on behalf of the Fund or the Adviser and shall survive delivery
of the Shares to the Underwriter.

     SECTION 9.   Termination of Agreement.
                  ------------------------

     (a)  Termination; General. The Underwriter may terminate this Agreement by
notice to the Fund, at any time at or prior to Closing Time (i) if there has
been, since the time of execution of this Agreement or since the respective

change in the condition, financial or otherwise, or in the earnings, business
affairs or business prospects of the Fund or the Adviser, whether or not arising
in the ordinary course of business, or (ii) if there has occurred any material
adverse change in the financial markets in the United States or the
international financial markets, any outbreak of hostilities or escalation
thereof or other calamity or crisis or any change or development involving a
prospective change in national or international political, financial or economic
conditions, in each case the effect of which is such as to make it, in the
judgment of the Underwriter, impracticable to market the Shares or to enforce
contracts for the sale of the Shares, or (iii) if trading in any securities of
the Fund has been suspended or materially limited by the Commission or the New
York Stock Exchange, or if trading generally on the American Stock Exchange or
the New York Stock Exchange or in the Nasdaq National Market has been suspended
or materially limited, or minimum or maximum prices for trading have been fixed,
or maximum ranges for prices for securities have been required, by any of said
exchanges or by such system or by order of the Commission, the National
Association of Securities Dealers, Inc. or any other governmental authority, or
(iv) if a banking moratorium has been declared by either Federal or New York
authorities.

     (b)  Liabilities. If this Agreement is terminated pursuant to this Section,
such termination shall be without liability of any party to any other party
except as provided in Section 4 hereof, and provided further that Sections 1, 6,
7 and 8 shall survive such termination and remain in full force and effect.

                       FORM OF OPINION OF FUND'S COUNSEL
                          TO BE DELIVERED PURSUANT TO
                                 SECTION 5(b)

     (i)    The Fund has been duly incorporated and is validly existing as a
corporation in good standing under the laws of the State of Maryland.

     (ii)   The Fund has corporate power and authority to own, lease and operate
its properties and to conduct its business as described in the Prospectus and to
enter into and perform its obligations under the Purchase Agreement.

     (iii)  The Fund is duly qualified as a foreign corporation to transact
business and is in good standing in each jurisdiction in which such
qualification is required, whether by reason of the ownership or leasing of
property or the conduct of business, except where the failure so to qualify or
to be in good standing would not result in a material adverse change in the
condition, financial or otherwise, or in the earnings, business affairs or
business prospects of the Fund, whether or not arising in the ordinary course of
business (a "Material Adverse Effect").

     (iv)   The authorized, issued and outstanding capital stock of the Fund is
as set forth in the Prospectus under the caption "Description of Capital Stock."

     (v)    The Shares to be purchased by the Underwriter from the Fund have
been duly authorized for issuance and sale to the Underwriter pursuant to the
Purchase Agreement and, when issued and delivered by the Fund pursuant to the
Purchase Agreement against payment of the consideration set forth in the
Purchase Agreement, will be validly issued and fully paid and non-assessable and
no holder of the Shares is or will be subject to personal liability by reason of
being such a holder.

     (vi)   The issuance of the Shares is not subject to the preemptive or other
similar rights of any securityholder of the Fund.

     (vii)  To the best of our knowledge, the Fund does not have any
subsidiaries.

     (viii) The Purchase Agreement has been duly authorized, executed and
delivered by the Fund and complies with all applicable provisions of the
Investment Company Act.

     (ix)   The Registration Statement, including any Rule 462(b) Registration
Statement, has been declared effective under the 1933 Act; any required filing
of the certificate pursuant to Rule 497(j) or the Prospectus pursuant to Rule
497(c) or Rule 497(h), as the case may be, has been made in the manner and
within the time period required by Rule 497(j), Rule 497(c) or Rule 497(h), as
the case may be; and, to the best of our knowledge, no stop order suspending the
effectiveness of the Registration Statement or any Rule 462(b) Registration
Statement has been

                                      A-1
<PAGE>
 
issued under the 1933 Act and no proceedings for that purpose have been
instituted or are pending or threatened by the Commission.

     (x)    The Registration Statement, including any Rule 462(b) Registration
Statement, the Rule 430A Information and the Rule 434 Information, as
applicable, the Prospectus, and each amendment or supplement to the Registration
Statement and the Prospectus, as of their respective effective or issue dates
(other than the financial statements and supporting schedules included therein
or omitted therefrom, as to which we need express no opinion) complied as to
form in all material respects with the requirements of the 1933 Act, the
Investment Company Act and the Rules and Regulations.

     (xi)   The form of certificate used to evidence the Common Stock complies
in all material respects with all applicable statutory requirements, with any
applicable requirements of the charter and by-laws of the Fund and the
requirements of the New York Stock Exchange.

     (xii)  To the best of our knowledge, there is not pending or threatened any
action, suit, proceeding, inquiry or investigation, to which the Fund is a
party, or to which the property of the Fund is subject, before or brought by any
court or governmental agency or body, domestic or foreign, which might
reasonably be expected to result in a Material Adverse Effect, or which might
reasonably be expected to materially and adversely affect the properties or
assets thereof or the consummation of the transactions contemplated in the
Purchase Agreement or the performance by the Fund of its obligations thereunder,
other than those disclosed in the Prospectus.

     (xiii) The information in the Prospectus under "Description of Capital
Stock" and "Taxes" and in the Registration Statement under Item 29, to the
extent that it constitutes matters of law, summaries of legal matters, the
Fund's charter and bylaws or legal proceedings, or legal conclusions, has been
reviewed by us and is correct in all material respects.

     (xiv)  To the best of our knowledge, there are no statutes or regulations
that are required to be described in the Prospectus that are not described as
required.

     (xv)   All descriptions in the Prospectus of contracts and other documents
to which the Fund is a party are accurate in all material respects; to the best
of our knowledge, there are no franchises, contracts, indentures, mortgages,
loan agreements, notes, leases or other instruments of the Fund required to be
described or referred to in the Registration Statement or to be filed as
exhibits thereto other than those described or referred to therein or filed or
incorporated by reference as exhibits thereto, and the descriptions thereof or
references thereto are correct in all material respects.

     (xvi)  To the best of our knowledge, the Fund is not in violation of its
charter or by-laws and no default by the Fund exists in the due performance or
observance of any material obligation, agreement, covenant or condition
contained in any contract, indenture, mortgage, loan agreement, note, lease or
other agreement or instrument that is described or referred to in the
Registration Statement or the Prospectus or filed or incorporated by reference
as an exhibit to the Registration Statement.

                                      A-2
<PAGE>
 
     (xvii)  No filing with, or authorization, approval, consent, license,
order, registration, qualification or decree of, any court or governmental
authority or agency, domestic or foreign (other than under the 1933 Act, the
Investment Company Act and the Rules and Regulations, which have been obtained,
or as may be required under the securities or blue sky laws of the various
states, as to which we need express no opinion) is necessary or required in
connection with the due authorization, execution and delivery of the Purchase
Agreement, the Advisory Agreement and the Custody Agreement or for the offering,
issuance, sale or delivery of the Shares.

     (xviii) The Advisory Agreement and the Custody Agreement have each been
duly authorized and approved by the Fund and comply as to form in all material
respects with all applicable provisions of the Investment Company Act, and each
has been duly executed by the Fund.

     (xix)   The Fund is registered with the Commission under the Investment
Company Act as a closed-end, non-diversified management investment company, and
all required action has been taken by the Fund under the 1933 Act, the
Investment Company Act and the Rules and Regulations to make the public offering
and consummate the sale of the Shares pursuant to the Purchase Agreement; the
provisions of the charter and the by-laws of the Fund comply as to form in all
material respects with the requirements of the Investment Company Act; and, to
the best of their knowledge and information, no order of suspension or
revocation of such registration under the Investment Company Act, pursuant to
Section 8(e) of the Investment Company Act, has been issued or proceedings
therefor initiated or threatened by the Commission.

     (xx)    The execution, delivery and performance of the Purchase Agreement
and the consummation of the transactions contemplated in the Purchase Agreement
and in the Registration Statement (including the issuance and sale of the
Shares, and the use of the proceeds from the sale of the Shares as described in
the Prospectus under the caption "Use of Proceeds") and compliance by the Fund
with its obligations under the Purchase Agreement do not and will not, whether
with or without the giving of notice or lapse of time or both, conflict with or
constitute a breach of, or default or Repayment Event (as defined in Section
1(a)(xi) of the Purchase Agreement) under or result in the creation or
imposition of any lien, charge or encumbrance upon any property or assets of the
Fund pursuant to any contract, indenture, mortgage, deed of trust, loan or
credit agreement, note, lease or any other agreement or instrument, known to us,
to which the Fund is a party or by which it may be bound, or to which any of the
property or assets of the Fund is subject (except for such conflicts, breaches
or defaults or liens, charges or encumbrances that would not have a Material
Adverse Effect), nor will such action result in any violation of the provisions
of the charter or by-laws of the Fund, or any applicable law, statute, rule,
regulation, judgment, order, writ or decree, known to us, of any government,
government instrumentality or court, domestic or foreign, having jurisdiction
over the Fund or any of its properties, assets or operations.

         Nothing has come to our attention that would lead us to believe that
the Registration Statement or any amendment thereto, including the Rule 430A
Information and Rule 434 Information (if applicable), (except for financial
statements and schedules and other financial data included or incorporated by
reference therein or omitted therefrom, as to which we need

                                      A-3
<PAGE>
 
make no statement), at the time such Registration Statement or any such
amendment became effective, contained an untrue statement of a material fact or
omitted to state a material fact required to be stated therein or necessary to
make the statements therein not misleading or that the Prospectus or any
amendment or supplement thereto (except for financial statements and schedules
and other financial data included or incorporated by reference therein or
omitted therefrom, as to which we need make no statement), at the time the
Prospectus was issued, at the time any such amended or supplemented prospectus
was issued or at the Closing Time, included or includes an untrue statement of a
material fact or omitted or omits to state a material fact necessary in order to
make the statements therein, in the light of the circumstances under which they
were made, not misleading.

     In rendering such opinion, such counsel may rely as to matters of fact (but
not as to legal conclusions), to the extent they deem proper, on certificates
and written statements of responsible officers of and accountants for the Fund
and the Adviser and public officials. Such opinion shall not state that it is to
be governed or qualified by, or that it is otherwise subject to, any treatise,
written policy or other document relating to legal opinions, including, without
limitation, the Legal Opinion Accord of the ABA Section of Business Law (1991).

                   FORM OF OPINION OF GENERAL COUNSEL TO THE
                      INVESTMENT ADVISER TO BE DELIVERED
                           PURSUANT TO SECTION 5(c)


     (i)    The Adviser has been duly organized as a limited partnership under
the laws of the State of Delaware, with power and authority to conduct its
business as described in the Registration Statement and in the Prospectus.

     (ii)   The Adviser is duly registered as an investment adviser under the
Investment Advisers Act and is not prohibited by the Investment Advisers Act or
the Investment Company Act, or the rules and regulations under such Acts, from
acting under the Advisory Agreement for the Fund as contemplated by the
Prospectus.

     (iii)  This Agreement and the Advisory Agreement have been duly authorized,
executed and delivered by the Adviser, and the Advisory Agreement constitutes a
valid and binding obligation of the Adviser, enforceable in accordance with its
terms, subject, as to enforcement, to bankruptcy, insolvency, reorganization or
other laws relating to or affecting creditors' rights and to general equity
principles; and, to the best of his knowledge and information, neither the
execution and delivery of this Agreement or the Advisory Agreement nor the
performance by the Adviser of its obligations hereunder or thereunder will
conflict with, or result in a breach of, any of the terms and provisions of, or
constitute, with or without the giving of notice or the lapse of time or both, a
default under, any agreement or instrument to which the Adviser is a party or by
which the Adviser is bound, or any law, order, rule or regulation applicable to
the Adviser of any jurisdiction, court, Federal or state regulatory body,
administrative agency or other governmental body, stock exchange or securities
association having jurisdiction over the Adviser or its properties or
operations.

     (iv)   To the best of his knowledge and information, the description of the
Adviser in the Registration Statement and in the Prospectus does not contain any
untrue statement of a material fact or omit to state any material fact required
to be stated therein or necessary to make the statements therein not misleading.

                             FORM OF ACCOUNTANTS'
                    COMFORT LETTER PURSUANT TO SECTION 5(e)

     1.   We are independent public accountants with respect to the Company
within the meaning of the 1933 Act and the 1933 Act Regulations.

     2.   In our opinion the financial statements audited by us and included in
the Registration Statement and the Prospectus comply as to form in all material
respects with the applicable accounting requirements of the 1933 Act, the
Investment Company Act and the Rules and Regulations.

     Such accountants shall also state that they have performed specified
procedures, not constituting an audit, including a reading of the latest
available interim financial statements of the Fund, a reading of the minute
books of the Fund, made inquiries of officials of the Fund responsible for
financial accounting matters and such other inquiries and procedures as may be
specified in such letter, and on the basis of such inquiries and procedures
nothing came to their attention that caused them to believe that at the date of
the latest available financial statements read by such accountants, or at a
subsequent specified date not more than three days prior to the date of the
Purchase Agreement, there was any change in the capital stock or net assets of
the Fund as compared with amounts shown on the financial statements included in
the Registration Statement and the Prospectus.

                           STANDARD DEALER AGREEMENT
                           -------------------------

Dear Sirs:

     In connection with public offerings of securities underwritten by us, or by
a group of underwriters (the "Underwriters") represented by us, you may be
offered the opportunity to purchase a portion of such securities, as principal,
at a discount from the offering price representing a selling concession or
reallowance granted as consideration for services rendered by you in the sale of
such securities. We request that you agree to the following terms and
provisions, and make the following representations, which, together with any
additional terms and provisions set forth in any wire or letter sent to you in
connection with a particular offering, will govern all such purchases of
securities and the reoffering thereof by you.

     Your subscription to, or purchase of, such securities will constitute your
reaffirmation of this Agreement.

     1.  When we are acting as representative (the "Representative") of the
Underwriters in offering securities to you, it should be understood that all
offers are made subject to prior sale of the subject securities, when, as and if
such securities are delivered to and accepted by the Underwriters and subject to
the approval of legal matters by their counsel. In such cases, any order from
you for securities will be strictly subject to confirmation and we reserve the
right in our uncontrolled discretion to reject any order in whole or in part.
Upon release by us, you may reoffer such securities at the offering price fixed
by us. With our consent, you may allow a discount, not in excess of the
reallowance fixed by us, in selling such securities to other dealers, provided
that in doing so you comply with the Rules of Fair Practice of the National
Association of Securities Dealers, Inc. (the "NASD"). Upon our request, you will
advise us of the identity of any dealer to whom you allow such a discount and
any Underwriter or dealer from whom you receive such a discount. After the
securities are released for sale to the public, we may vary the offering price
and other selling terms.

     2.  You represent that you are a dealer actually engaged in the investment
banking or securities business and that you are either (i) a member in good
standing of the NASD or (ii) a dealer with its principal place of business
located outside the United States, its territories or possessions and not
registered under the Securities Exchange Act of 1934 (a "non-member foreign
dealer") or (iii) a bank not eligible for membership in the NASD.  If you are a
non-member foreign dealer, you agree to make no sales of securities within the
United States, its
<PAGE>
 
territories or its possessions or to persons who are nationals thereof or
residents therein. Non-member foreign dealers and banks agree, in making any
sales, to comply with the NASD's interpretation with respect to free-riding and
withholding. In accepting a selling concession where we are acting as
Representative of the Underwriters, in accepting a reallowance from us whether
or not we are acting as such Representative, and in allowing a discount to any
other person, you agree to comply with the provisions of Section 24 of Article
III of the Rules of Fair Practice of the NASD, and, in addition, if you are a
non-member foreign dealer or bank, you agree to comply, as though you were a
member of the NASD, with the provisions of Sections 8 and 36 of Article III of
such Rules of Fair Practice and to comply with Section 25 of Article III thereof
as that Section applies to a non-member foreign dealer or bank. You represent
that you are fully familiar with the above provisions of the Rules of Fair
Practice of the NASD.

     3.  If the securities have been registered under the Securities Act of 1933
(the "1933 Act"), in offering and selling such securities, you are not
authorized to give any information or make any representation not contained in
the prospectus relating thereto. You confirm that you are familiar with the
rules and policies of the Securities and Exchange Commission relating to the
distribution of preliminary and final prospectuses, and you agree that you will
comply therewith in any offering covered by this Agreement. If we are acting as
Representative of the Underwriters, we will make available to you, to the extent
made available to us by the issuer of the securities, such number of copies of
the prospectus or offering documents, for securities not registered under the
1933 Act, as you may reasonably request.

     4.  If we are acting as Representative of the Underwriters of securities of
an issuer that is not required to file reports under the Securities Exchange Act
of 1934 (the "1934 Act"), you agree that you will not sell any of the securities
to any account over which you have discretionary authority.

     5.  Payment for securities purchased by you is to be made at our office,
Merrill Lynch World Headquarters North Tower World Financial Center New York,
N.Y. 10281-1305 (or at such other place as we may advise), at the offering price
less the concession allowed to you, on such date as we may advise, by certified
or official bank check in New York Clearing House funds (or such other funds as
we may advise), payable to our order, against delivery of the securities to be
purchased by you. We shall have authority to make appropriate arrangements for
payment for and/or delivery through the facility of The Depository Trust Company
or any such other depository or similar facility for the securities.

     6.  In the event that, prior to the completion of the distribution of
securities covered by this Agreement, we purchase in the open market or
otherwise any securities delivered to you, if we are acting as Representative of
the Underwriters, you agree to repay to us for the accounts of the Underwriters
the amount of the concession allowed to you plus brokerage commissions and any
transfer taxes paid in connection with such purchase.

     7.  At any time prior to the completion of the distribution of securities
covered by this Agreement you will, upon our request as Representative of the
Underwriters, report to us the amount of securities purchased by you which then
remains unsold and will, upon our request, sell to us for the account of one or
more of the Underwriters such amount of such unsold

                                       2
<PAGE>
 
securities as we may designate, at the offering price less an amount to be
determined by us not in excess of the concession allowed to you.

     8.  If we are acting as Representative of the Underwriters, upon
application to us, we will inform you of the states and other jurisdictions of
the United States in which it is believed that the securities being offered are
qualified for sale under, or are exempt from the requirements of, their
respective securities laws, but we assume no responsibility with respect to your
right to sell securities in any jurisdiction. We shall have authority to file
with the Department of State of the State of New York a Further State Notice
with respect to the securities, if necessary.

     9.  You agree that in connection with any offering of securities covered by
this Agreement you will comply with the applicable provisions of the 1933 Act
and the 1934 Act and the applicable rules and regulations of the Securities and
Exchange Commission thereunder, the applicable rules and regulations of the
NASD, and the applicable rules of any securities exchange having jurisdiction
over the offering.

     10.  We shall have full authority to take such action as we may deem
advisable in respect of all matters pertaining to any offering covered by this
Agreement. We shall be under no liability to you except for our lack of good
faith and for obligations assumed by us in this Agreement, except that you do
not waive any rights that you may have under the 1933 Act or the rules and
regulations thereunder.

     11.  Any notice from us shall be deemed to have been duly given if mailed
or transmitted by any standard form of written telecommunications to you at the
above address or at such other address as you shall specify to us in writing.

     12.  With respect to any offering of securities covered by this Agreement,
the price restrictions contained in Paragraph 1 hereof and the provisions of
Paragraphs 6 and 7 hereof shall terminate as to such offering at the close of
business on the 45th day after the securities are released for sale or, as to
any or all such provisions, at such earlier time as we may advise.  All other
provisions of this Agreement shall remain operative and in full force and effect
with respect to such offering.

     13.  This Agreement shall be governed by the laws of the State of New York.

                                       3

  resolution of the Board of Directors of the Fund, substantially in the form of

  Securities, loans of

                                      -5-
<PAGE>
 
  Securities and deliveries and returns of Securities collateral. Prior to a
  deposit of Securities specifically allocated to a Series in the Depository,
  the Fund shall deliver to the Custodian a certified resolution of the Board of
  Directors of the Fund, substantially in the form of Exhibit B hereto,
  approving, authorizing and instructing the Custodian on a continuous and
  ongoing basis until instructed to the contrary by a Certificate actually
  received by the Custodian to deposit in the Depository all Securities
  specifically allocated to such Series eligible for deposit therein, and to
  utilize the Depository to the extent possible with respect to such Securities
  in connection with its performance hereunder, including, without limitation,
  in connection with settlements of purchases and sales of Securities, loans of
  Securities, and deliveries and returns of Securities collateral. Securities
  and moneys deposited in either the Book-Entry System or the Depository will be
  represented in accounts which include only assets held by the Custodian for
  customers, including, but not limited to, accounts in which the Custodian acts
  in a fiduciary or representative capacity and will be specifically allocated
  on the Custodian's books to the separate account for the applicable Series.
  Prior to the Custodian's accepting, utilizing and acting with respect to
  Clearing Member confirmations for Options and transactions in Options for a
  Series as provided in this Agreement, the Custodian shall have received a
  certified resolution of the Fund's Board of Directors, substantially in the
  form of Exhibit C hereto, approving, authorizing and instructing the Custodian
  on a continuous and on-going basis, until instructed to the contrary by a
  Certificate actually received by the Custodian, to accept, utilize and act in
  accordance with such confirmations as provided in this Agreement with respect
  to such Series.

         2. The Custodian shall establish and maintain separate accounts, in the
  name of each Series, and shall credit to the separate account for each Series
  all moneys received by it for the account of the Fund with respect to such
  Series. Money credited to a separate account for a Series shall be disbursed
  by the Custodian only:

                 (a) as hereinafter provided;

                 (b) pursuant to Certificates setting forth the name and address
  of the person to whom the payment is to be made, the Series account from which
  payment is to be made and the purpose for which payment is to be made; or

                 (c) in payment of the fees and in reimbursement of the expenses
  and liabilities of the Custodian attributable to such Series.

         3. Promptly after the close of business on each day, the Custodian
  shall furnish the Fund with confirmations and a summary, on a per Series
  basis, of all transfers to or from

                                      -6-
<PAGE>
 
  the account of the Fund for a Series, either hereunder or with any co-
  custodian or sub-custodian appointed in accordance with this Agreement during
  said day. Where Securities are transferred to the account of the Fund for a
  Series, the Custodian shall also by book-entry or otherwise identify as
  belonging to such Series a quantity of Securities in a fungible bulk of
  Securities registered in the name of the Custodian (or its nominee) or shown
  on the Custodian's account on the books of the Book-Entry System or the
  Depository. At least monthly and from time to time, the Custodian shall
  furnish the Fund with a detailed statement, on a per Series basis, of the
  Securities and moneys held by the Custodian for the Fund.

         4. Except as otherwise provided in paragraph 7 of this Article and in
  Article VIII, all Securities held by the Custodian hereunder, which are issued
  or issuable only in bearer form, except such Securities as are held in the
  Book-Entry System, shall be held by the Custodian in that form; all other
  Securities held hereunder may be registered in the name of the Fund, in the
  name of any duly appointed registered nominee of the Custodian as the
  Custodian may from time to time determine, or in the name of the Book-Entry
  System or the Depository or their successor or successors, or their nominee or
  nominees. The Fund agrees to furnish to the Custodian appropriate instruments
  to enable the Custodian to hold or deliver in proper form for transfer, or to
  register in the name of its registered nominee or in the name of the
  Book-Entry System or the Depository any Securities which it may hold hereunder
  and which may from time to time be registered in the name of the Fund. The
  Custodian shall hold all such Securities specifically allocated to a Series
  which are not held in the Book-Entry System or in the Depository in a separate
  account in the name of such Series physically segregated at all times from
  those of any other person or persons.

         5. Except as otherwise provided in this Agreement and unless otherwise
  instructed to the contrary by a Certificate, the Custodian by itself, or
  through the use of the Book-Entry System or the Depository with respect to
  Securities held hereunder and therein deposited, shall with respect to all
  Securities held for the Fund hereunder in accordance with preceding paragraph
  4:

                (a) collect all income, dividends and distributions due or
  payable;

                (b) give notice to the Fund and present payment and collect the
  amount payable upon such Securities which are called, but only if either (i)
  the Custodian receives a written notice of such call, or (ii) notice of such
  call appears in one or more of the publications listed in Appendix C annexed
  hereto, which may be amended at any time by the

                                      -7-
<PAGE>
 
  Custodian without the prior notification or consent of the Fund;

                 (c) present for payment and collect the amount payable upon all
  Securities which mature;

                 (d) surrender Securities in temporary form for definitive
  Securities;

                 (e) execute, as custodian, any necessary declarations or

                          OVERDRAFTS OR INDEBTEDNESS

         1. If the Custodian, should in its sole discretion advance funds on
  behalf of any Series which results in an overdraft because the moneys held by
  the Custodian in the separate account for such Series shall be insufficient to
  pay the total amount payable upon a purchase of Securities specifically
  allocated to such Series, as set forth in a Certificate or Oral Instructions,
  or which results in an overdraft in the separate account of such Series for
  some other reason, or if the Fund is for any other reason indebted to the
  Custodian with respect to a Series, including any indebtedness to The Bank of
  New York under the Fund's Cash Management and Related Services Agreement,
  (except a borrowing for investment or for temporary or emergency purposes
  using Securities as collateral pursuant to a separate agreement and subject to
  the provisions of paragraph 2 of this Article), such overdraft or indebtedness
  shall be deemed to be a loan made by the Custodian to the Fund for such Series
  payable on demand and shall bear interest from the date incurred at a

                                      -26-
<PAGE>
 
  rate per annum (based on a 360-day year for the actual number of days
  involved) equal to 1/2% over Custodian's prime commercial lending rate in
  effect from time to time, such rate to be adjusted on the effective date of
  any change in such prime commercial lending rate but in no event to be less
  than 6% per annum. In addition, the Fund hereby agrees that the Custodian
  shall have a continuing lien and security interest in and to any property
  specifically allocated to such Series at any time held by it for the benefit
  of such Series or in which the Fund may have an interest which is then in the
  Custodian's possession or control or in possession or control of any third
  party acting in the Custodian's behalf. The Fund authorizes the Custodian, in
  its sole discretion, at any time to charge any such overdraft or indebtedness
  together with interest due thereon against any balance of account standing to
  such Series' credit on the Custodian's books. In addition, the Fund hereby
  covenants that on each Business Day on which either it intends to enter a
  Reverse Repurchase Agreement and/or otherwise borrow from a third party, or
  which next succeeds a Business Day on which at the close of business the Fund
  had outstanding a Reverse Repurchase Agreement or such a borrowing, it shall
  prior to 9 a.m., New York City time, advise the Custodian, in writing, of each
  such borrowing, shall specify the Series to which the same relates, and shall
  not incur any indebtedness not so specified other than from the Custodian.

         2. The Fund will cause to be delivered to the Custodian by any bank
  (including, if the borrowing is pursuant to a separate agreement, the
  Custodian) from which it borrows money for investment or for temporary or
  emergency purposes using Securities held by the Custodian hereunder as
  collateral for such borrowings, a notice or undertaking in the form currently
  employed by any such bank setting forth the amount which such bank will loan
  to the Fund against delivery of a stated amount of collateral. The Fund shall
  promptly deliver to the Custodian a Certificate specifying with respect to
  each such borrowing: (a) the Series to which such borrowing relates; (b) the
  name of the bank, (c) the amount and terms of the borrowing, which may be set
  forth by incorporating by reference an attached promissory note, duly endorsed
  by the Fund, or other loan agreement, (d) the time and date, if known, on
  which the loan is to be entered into, (e) the date on which the loan becomes
  due and payable, (f) the total amount payable to the Fund on the borrowing
  date, (g) the market value of Securities to be delivered as collateral for
  such loan, including the name of the issuer, the title and the number of
  shares or the principal amount of any particular Securities, and (h) a
  statement specifying whether such loan is for investment purposes or for
  temporary or emergency purposes and that such loan is in conformance with the
  Investment Company Act of 1940 and the Fund's prospectus. The Custodian shall
  deliver on the borrowing date specified in a Certificate the specified
  collateral and the executed promissory note, if any, against delivery by the
  lending bank of the total amount of

                                      -27-
<PAGE>
 
  the loan payable, provided that the same conforms to the total amount payable
  as set forth in the Certificate. The Custodian may, at the option of the
  lending bank, keep such collateral in its possession, but such collateral
  shall be subject to all rights therein given the lending bank by virtue of any
  promissory note or loan agreement. The Custodian shall deliver such Securities
  as additional collateral as may be specified in a Certificate to collateralize
  further any transaction described in this paragraph. The Fund shall cause all
  Securities released from collateral status to be returned directly to the
  Custodian, and the Custodian shall receive from time to time such return of
  collateral as may be tendered to it. In the event that the Fund fails to
  specify in a Certificate the Series, the name of the issuer, the title and
  number of shares or the principal amount of any particular Securities to be
  delivered as collateral by the Custodian, the Custodian shall not be under any
  obligation to deliver any Securities.

  equipment and services, including but not limited to communications services,
  necessary for it to utilize the Software and transmit Instructions to the
  Custodian. The Custodian shall not be responsible for the reliability,
  compatibility with the Software or availability of any such equipment or
  services or the performance or nonperformance by any nonparty to this Custody
  Agreement.

         3. The Fund acknowledges that the Software, all data bases made
  available to the Fund by utilizing the Software (other than data bases
  relating solely to the assets of the Fund and transactions with respect
  thereto), and any proprietary data, processes, information and documentation
  (other than which are or become part of the public domain or are legally
  required to be made available to the public) (collectively, the
  "Information"), are the exclusive and confidential property of the Custodian.
  The Fund shall keep

                                      -28-
<PAGE>
 
  the Information confidential by using the same care and discretion that the
  Fund uses with respect to its own confidential property and trade secrets and
  shall neither make nor permit any disclosure without the prior written consent
  of the Custodian. Upon termination of this Agreement or the Software license
  granted hereunder for any reason, the Fund shall return to the Custodian all
  copies of the Information which are in its possession or under its control or
  which the Fund distributed to third parties.

         4. The Custodian reserves the right to modify the Software from time to
  time upon reasonable prior notice and the Fund shall install new releases of
  the Software as the Custodian may direct. The Fund agrees not to modify or
  attempt to modify the Software without the Custodian's prior written consent.
  The Fund acknowledges that any modifications to the Software, whether by the
  Fund or the Custodian and whether with or without the Custodian's consent,
  shall become the property of the Custodian.

         5. The Custodian makes no warranties or representations of any kind
  with regard to the Software or the method(s) by which the Fund may transmit
  Instructions to the Custodian, express or implied, including but not limited
  to any implied warranties or merchantability or fitness for a particular
  purpose.

         6. Where the method for transmitting Instructions by the Fund involves
  an automatic systems acknowledgment by the Custodian of its receipt of such
  Instructions, then in the absence of such acknowledgment the Custodian shall
  not be liable for any failure to act pursuant to such Instructions, the Fund
  may not claim that such Instructions were received by the Custodian, and the
  Fund shall deliver a Certificate by some other means.

         7. (a) The Fund agrees that where it delivers to the Custodian
  Instructions hereunder, it shall be the Fund's sole responsibility to ensure
  that only persons duly authorized by the Fund transmit such Instructions to
  the Custodian. The Fund will cause all persons transmitting Instructions to
  the Custodian to treat applicable user and authorization codes, passwords and
  authentication keys with extreme care, and irrevocably authorizes the
  Custodian to act in accordance with and rely upon Instructions received by it
  pursuant hereto.

                (b) The Fund hereby represents, acknowledges and agrees that it
  is fully informed of the protections and risks associated with the various
  methods of transmitting Instructions to the Custodian and that there may be
  more secure methods of transmitting Instructions to the Custodian than the
  method(s) selected by the Fund. The Fund hereby agrees that the security
  procedures (if any) to be followed in connection with the Fund's transmission
  of Instructions

                                      -29-
<PAGE>
 
  provide to it a commercially reasonable degree of protection in light of its
  particular needs and circumstances.

         8. The Fund hereby presents, warrants and covenants to the Custodian
  that this Agreement has been duly approved by a resolution of its Board of
  Directors, and that its transmission of Instructions pursuant hereto shall at
  all times comply with the Investment Company Act of 1940, as amended.

         9. The Fund shall notify the Custodian of any errors, omissions or
  interruptions in, or delay or unavailability of, its ability to send
  Instructions as promptly as practicable, and in any event within 24 hours
  after the earliest of (i) discovery thereof, (ii) the Business Day on which
  discovery should have occurred through the exercise of reasonable care and
  (iii) in the case of any error, the date of actual receipt of the earliest
  notice which reflects such error, it being agreed that discovery and receipt
  of notice may only occur on a business day. The Custodian shall promptly
  advise the Fund whenever the Custodian learns of any errors, omissions or
  interruption in, or delay or unavailability of, the Fund's ability to send
  Instructions.

                                   ARTICLE XVI.

               DUTIES OF THE CUSTODIAN WITH RESPECT TO PROPERTY
                OF ANY SERIES HELD OUTSIDE OF THE UNITED STATES

         1. The Custodian is authorized and instructed to employ, as
  sub-custodian for each Series' Foreign Securities (as such term is defined in
  paragraph (c)(1) of Rule 17f-5 under the Investment Company Act of 1940, as
  amended) and other assets, the foreign banking institutions and foreign
  securities depositories and clearing agencies designated on Schedule I hereto
  ("Foreign Sub-Custodians") to carry out their respective responsibilities in
  accordance with the terms of the sub-custodian agreement between each such
  Foreign Sub-Custodian and the Custodian, copies of which have been previously
  delivered to the Fund and receipt of which is hereby acknowledged (each such
  agreement, a "Foreign Sub-Custodian Agreement"). Upon receipt of a
  Certificate, together with a certified resolution substantially in the form
  attached as Exhibit E of the Fund's Board of Directors, the Fund may designate
  any additional foreign sub-custodian with which the Custodian has an agreement
  for such entity to act as the Custodian's agent, as its sub-custodian and any
  such additional foreign sub-custodian shall be deemed added to Schedule I.
  Upon receipt of a Certificate from the Fund, the Custodian shall cease the
  employment of any one or more Foreign Sub-Custodians for maintaining custody
  of the Fund's assets and such Foreign Sub-Custodian shall be deemed deleted
  from Schedule I.

                                      -30-
<PAGE>
 
          2. Each Foreign Sub-Custodian Agreement shall be substantially in the
   form previously delivered to the Fund and will not be amended in a way that
   materially adversely affects the Fund without the Fund's prior written
   consent.

          3. The Custodian shall identify on its books as belonging to each
  Series of the Fund the Foreign Securities of such Series held by each Foreign
  Sub-Custodian. At the election of the Fund, it shall be entitled to be
  subrogated to the rights of the Custodian with respect to any claims by the
  Fund or any Series against a Foreign Sub-Custodian as a consequence of any
  loss, damage, cost, expense, liability or claim sustained or incurred by the
  Fund or any Series if and to the extent that the Fund or such Series has not
  been made whole for any such loss, damage, cost, expense, liability or claim. 

          4. Upon request of the Fund, the Custodian will, consistent with the
  terms of the applicable Foreign Sub Custodian Agreement, use reasonable
  efforts to arrange for the independent accountants of the Fund to be afforded
  access to the books and records of any Foreign Sub-Custodian insofar as such
  books and records relate to the performance of such Foreign Sub-Custodian
  under its agreement with the Custodian on behalf of the Fund.
  
          5. The Custodian will supply to the Fund from time to time, as
  mutually agreed upon, statements in respect of the securities and other assets
  of each Series held by Foreign Sub-Custodians, including but not limited to,
  an identification of entities having possession of each Series' Foreign
  Securities and other assets, and advices or notifications of any transfers of
  Foreign Securities to or from each custodial account maintained by a Foreign
  Sub-Custodian for the Custodian on behalf of the Series.
  
          6. The Custodian shall furnish annually to the Fund, as mutually
  agreed upon, information concerning the Foreign Sub-Custodians employed by the
  Custodian. Such information shall be similar in kind and scope to that
  furnished to the Fund in connection with the Fund's initial approval of such
  Foreign Sub-Custodians and, in any event, shall include information pertaining
  to (i) the Foreign Custodians' financial strength, general reputation and
  standing in the countries in which they are located and their ability to
  provide the custodial services required, and (ii) whether the Foreign Sub-
  Custodians would provide a level of safeguards for safekeeping and custody of
  securities not materially different from those prevailing in the United
  States. The Custodian shall monitor the general operating performance of each
  Foreign Sub-Custodian. The Custodian agrees that it will use reasonable care
  in monitoring compliance by each Foreign Sub-Custodian with the terms of the
  relevant Foreign Sub-Custodian Agreement
  
                                      -31-
<PAGE>
 
  and that if it learns of any breach of such Foreign Sub-Custodian Agreement
  believed by the Custodian to have a material adverse effect on the Fund or any
  Series it will promptly notify the Fund of such breach. The Custodian also
  agrees to use reasonable and diligent efforts to enforce its rights under the
  relevant Foreign Sub-Custodian Agreement.

         7. The Custodian shall transmit promptly to the Fund all notices,
  reports or other written information received pertaining to the Fund's Foreign
  Securities, including without limitation, notices of corporate action, proxies
  and proxy solicitation materials.

         8. Notwithstanding any provision of this Agreement to the contrary,
  settlement and payment for securities received for the account of any Series
  and delivery of securities maintained for the account of such Series may be
  effected in accordance with the customary or established securities trading
  or securities processing practices and procedures in the jurisdiction or
  market in which the transaction occurs, including, without limitation,
  delivery of securities to the purchaser thereof or to a dealer therefor (or an
  agent for such purchaser or dealer) against a receipt with the expectation of
  receiving later payment for such securities from such purchaser or dealer.

         9. Notwithstanding any other provision in this Agreement to the
  contrary, with respect to any losses or damages arising out of or relating to
  any actions or omissions of any Foreign Sub-Custodian the sole responsibility
  and liability of the Custodian shall be to take appropriate action at the
  Fund's expense to recover such loss or damage from the Foreign Sub-Custodian.
  It is expressly understood and agreed that the Custodian's sole responsibility
  and liability shall be limited to amounts so recovered from the Foreign
  Sub-Custodian.

                                 ARTICLE XVII.

                                FX TRANSACTIONS

         1. Whenever the Fund shall enter into an FX Transaction, the Fund shall
  promptly deliver to the Custodian a Certificate or Oral Instructions
  specifying with respect to such FX Transaction: (a) the Series to which such
  FX Transaction is specifically allocated; (b) the type and amount of Currency
  to be purchased by the Fund; (c) the type and amount of Currency to be sold by
  the Fund; (d) the date on which the Currency to be purchased is to be
  delivered; (e) the date on which the Currency to be sold is to be delivered;
  and (f) the name of the person from whom or through whom such currencies are
  to be purchased and sold. Unless otherwise instructed by a Certificate or Oral
  Instructions, the

                                      -32-
<PAGE>
 
  Custodian shall deliver, or shall instruct a Foreign Sub-Custodian to deliver,
  the Currency to be sold on the date on which such delivery is to be made, as
  set forth in the Certificate, and shall receive, or instruct a Foreign
  Sub-Custodian to receive, the Currency to be purchased on the date as set
  forth in the Certificate.

         2. Where the Currency to be sold is to be delivered on the same day as
  the Currency to be purchased, as specified in the Certificate or Oral
  Instructions, the Custodian or a Foreign Sub-Custodian may arrange for such
  deliveries and receipts to be made in accordance with the customs prevailing
  from time to time among brokers or dealers in Currencies, and such receipt and
  delivery may not be completed simultaneously. The Fund assumes all
  responsibility and liability for all credit risks involved in connection with
  such receipts and deliveries, which responsibility and liability shall
  continue until the Currency to be received by the Fund has been received in
  full.

         3. Any FX Transaction effected by the Custodian in connection with this
  Agreement may be entered with the Custodian, any office, branch or subsidiary
  of The Bank of New York Company, Inc., or any Foreign Sub-Custodian acting as
  principal or otherwise through customary banking channels. The Fund may issue
  a standing Certificate with respect to FX Transaction but the Custodian may
  establish rules or limitations concerning any foreign exchange facility made
  available to the Fund. The Fund shall bear all risks of investing in
  Securities or holding Currency. Without limiting the foregoing, the Fund shall
  bear the risks that rules or procedures imposed by a Foreign Sub-Custodian or
  foreign depositories, exchange controls, asset freezes or other laws, rules,
  regulations or orders shall prohibit or impose burdens or costs on the
  transfer to, by or for the account of the Fund of Securities or any cash held
  outside the Fund's jurisdiction or denominated in Currency other than its home
  jurisdiction or the conversion of cash from one Currency into another
  currency. The Custodian shall not be obligated to substitute another Currency
  for a Currency (including a Currency that is a component of a Composite
  Currency Unit) whose transferability, convertibility or availability has been
  affected by such law, regulation, rule or procedure. Neither the Custodian nor
  any Foreign Sub-Custodian shall be liable to the Fund for any loss resulting
  from any of the foregoing events.

                                ARTICLE XVIII.

                           CONCERNING THE CUSTODIAN

         1. Except as hereinafter provided, or as provided in Article XVI,
  neither the Custodian nor its nominee shall be

                                      -33-
<PAGE>
 
  liable for any loss or damage, including counsel fees, resulting from its
  action or omission to act or otherwise, either hereunder or under any Margin
  Account Agreement, except for any such loss or damage arising out of its own
  negligence or willful misconduct. In no event shall the Custodian be liable to
  the Fund or any third party for special, indirect or consequential damages or
  lost profits or loss of business, arising under or in connection with this
  Agreement, even if previously informed of the possibility of such damages and
  regardless of the form of action. The Custodian may, with respect to questions
  of law arising hereunder or under any Margin Account Agreement, apply for and
  obtain the advice and opinion of counsel to the Fund or of its own counsel, at
  the expense of the Fund, and shall be fully protected with respect to anything
  done or omitted by it in good faith in conformity with such advice or opinion.
  The Custodian shall be liable to the Fund for any loss or damage resulting
  from the use of the Book-Entry System or any Depository arising by reason of
  any negligence or willful misconduct on the part of the Custodian or any of
  its employees or agents.

         2. Without limiting the generality of the foregoing, the Custodian
  shall be under no obligation to inquire into, and shall not be liable for:

                 (a) the validity of the issue of any Securities purchased,
  sold, or written by or for the Fund, the legality of the purchase, sale or
  writing thereof, or the propriety of the amount paid or received therefor;

                 (b) the legality of the sale or redemption of any Shares, or
  the propriety of the amount to be received or paid therefor;

                 (c) the legality of the declaration or payment of any dividend
  by the Fund;

                 (d) the legality of any borrowing by the Fund using Securities
  as collateral;

                 (e) the legality of any loan of portfolio Securities, nor shall
  the Custodian be under any duty or obligation to see to it that any cash
  collateral delivered to it by a broker, dealer, or financial institution or
  held by it at any time as a result of such loan of portfolio Securities of the
  Fund is adequate collateral for the Fund against any loss it might sustain as
  a result of such loan. The Custodian specifically, but not by way of
  limitation, shall not be under any duty or obligation periodically to check or
  notify the Fund that the amount of such cash collateral held by it for the
  Fund is sufficient collateral for the Fund, but such duty or obligation shall
  be the sole responsibility of the Fund. In addition, the Custodian shall be
  under no duty or obligation to see that any broker, dealer or financial
  institution

                                      -34-
<PAGE>
 
  to which portfolio Securities of the Fund are lent pursuant to Article X of
  this Agreement makes payment to it of any dividends or interest which are
  payable to or for the account of the Fund during the period of such loan or at
  the termination of such loan, provided, however, that the Custodian shall
  promptly notify the Fund in the event that such dividends or interest are not
  paid and received when due; or

                 (f) the sufficiency or value of any amounts of money and/or
  Securities held in any Margin Account, Senior Security Account or Collateral
  Account in connection with transactions by the Fund. In addition, the
  Custodian shall be under no duty or obligation to see that any broker, dealer,
  futures commission merchant or Clearing Member makes payment to the Fund of
  any variation margin payment or similar payment which the Fund may be entitled
  to receive from such broker, dealer, futures commission merchant or Clearing
  Member, to see that any payment received by the Custodian from any broker,
  dealer, futures commission merchant or Clearing Member is the amount the Fund
  is entitled to receive, or to notify the Fund of the Custodian's receipt or
  non-receipt of any such payment.

         3. The Custodian shall not be liable for, or considered to be the
  Custodian of, any money, whether or not represented by any check, draft, or
  other instrument for the payment of money, received by it on behalf of the
  Fund until the Custodian actually receives and collects such money directly or
  by the final crediting of the account representing the Fund's interest at the
  Book-Entry System or the Depository.

         4. The Custodian shall have no responsibility and shall not be liable
  for ascertaining or acting upon any calls, conversions, exchange offers,
  tenders, interest rate changes or similar matters relating to Securities held
  in the Depository, unless the Custodian shall have actually received timely
  notice from the Depository. In no event shall the Custodian have any
  responsibility or liability for the failure of the Depository to collect, or
  for the late collection or late crediting by the Depository of any amount
  payable upon Securities deposited in the Depository which may mature or be
  redeemed, retired, called or otherwise become payable. However, upon receipt
  of a Certificate from the Fund of an overdue amount on Securities held in the
  Depository the Custodian shall make a claim against the Depository on behalf
  of the Fund, except that the Custodian shall not be under any obligation to
  appear in, prosecute or defend any action suit or proceeding in respect to any
  Securities held by the Depository which in its opinion may involve it in
  expense or liability, unless indemnity satisfactory to it against all expense
  and liability be furnished as often as may be required.

                                      -35-
<PAGE>
 
         5. The Custodian shall not be under any duty or obligation to
   take action to effect collection of any amount due to the Fund from the
   Transfer Agent of the Fund nor to take any action to effect payment or
   distribution by the Transfer Agent of the Fund of any amount paid by the
   Custodian to the Transfer Agent of the Fund in accordance with this
   Agreement.

         6. The Custodian shall not be under any duty or obligation to take
  action to effect collection of any amount if the Securities upon which such
  amount is payable are in default, or if payment is refused after due demand or
  presentation, unless and until (i) it shall be directed to take such action by
  a Certificate and (ii) it shall be assured to its satisfaction of
  reimbursement of its costs and expenses in connection with any such action.

         7. The Custodian may in addition to the employment of Foreign
  Sub-Custodians pursuant to Article XVI appoint one or more banking
  institutions as Depository or Depositories, as Sub-Custodian or
  Sub-Custodians, or as Co-Custodian or Co-Custodians including, but not limited
  to, banking institutions located in foreign countries, of Securities and
  moneys at any time owned by the Fund, upon such terms and conditions as may be
  approved in a Certificate or contained in an agreement executed by the
  Custodian, the Fund and the appointed institution.

         8. The Custodian shall not be under any duty or obligation (a) to
  ascertain whether any Securities at any time delivered to, or held by it or by
  any Foreign Sub-Custodian, for the account of the Fund and specifically
  allocated to a Series are such as properly may be held by the Fund or such
  Series under the provisions of its then current prospectus, or (b) to
  ascertain whether any transactions by the Fund, whether or not involving the
  Custodian, are such transactions as may properly be engaged in by the Fund.

         9. The Custodian shall be entitled to receive and the Fund agrees to
  pay to the Custodian all out-of-pocket expenses and such compensation as may
  be agreed upon from time to time between the Custodian and the Fund. The
  Custodian may charge such compensation and any expenses with respect to a
  Series incurred by the Custodian in the performance of its duties pursuant to
  such agreement against any money specifically allocated to such Series. Unless
  and until the Fund instructs the Custodian by a Certificate to apportion any
  loss, damage, liability or expense among the Series in a specified manner, the
  Custodian shall also be entitled to charge against any money held by it for
  the account of a Series such Series' pro rata share (based on such Series net
  asset value at the time of the charge to the aggregate net asset value of all
  Series at that time) of the amount of any loss, damage, liability or expense,
  including counsel fees, for which it shall be

                                                                         .

                                      -36-
<PAGE>
 
  entitled to reimbursement under the provisions of this Agreement. The
  expenses for which the Custodian shall be entitled to reimbursement hereunder
  shall include, but are not limited to, the expenses of sub-custodians and
  foreign branches of the Custodian incurred in settling outside of New York
  City transactions involving the purchase and sale of Securities of the Fund.

         10. The Custodian shall be entitled to rely upon any Certificate,
  notice or other instrument in writing received by the Custodian and reasonably
  believed by the Custodian to be a Certificate. The Custodian shall be entitled
  to rely upon any Oral Instructions actually received by the Custodian
  hereinabove provided for. The Fund agrees to forward to the Custodian a
  Certificate or facsimile thereof confirming such Oral Instructions in such
  manner so that such Certificate or facsimile thereof is received by the
  Custodian, whether by hand delivery, telecopier or other similar device, or
  otherwise, by the close of business of the same day that such Oral
  Instructions are given to the Custodian. The Fund agrees that the fact that
  such confirming instructions are not received, or that contrary instructions
  are received, by the Custodian shall in no way affect the validity of the
  transactions or enforceability of the transactions hereby authorized by the
  Fund. The Fund agrees that the Custodian shall incur no liability to the Fund
  in acting upon Oral Instructions given to the Custodian hereunder concerning
  such transactions provided such instructions reasonably appear to have been
  received from an Officer.

         11. The Custodian shall be entitled to rely upon any instrument,
  instruction or notice received by the Custodian and reasonably believed by the
  Custodian to be given in accordance with the terms and conditions of any
  Margin Account Agreement. Without limiting the generality of the foregoing,
  the Custodian shall be under no duty to inquire into, and shall not be liable
  for, the accuracy of any statements or representations contained in any such
  instrument or other notice including, without limitation, any specification of
  any amount to be paid to a broker, dealer, futures commission merchant or
  Clearing Member.

         12. The books and records pertaining to the Fund which are in the
  possession of the Custodian shall be the property of the Fund. Such books and
  records shall be prepared and maintained as required by the Investment Company
  Act of 1940, as amended, and other applicable securities laws and rules and
  regulations. The Fund, or the Fund's authorized representatives, shall have
  access to such books and records during the Custodian's normal business hours.
  Upon the reasonable request of the Fund, copies of any such books and records
  shall be provided by the Custodian to the Fund or the Fund's authorized
  representative, and the Fund shall reimburse the

                                      -37-
<PAGE>
 
  Custodian its expenses of providing such copies. Upon reasonable request of
  the Fund, the Custodian shall provide in hard copy or on microfilm, whichever
  the Custodian elects, any records included in any such delivery which are
  maintained by the Custodian on a computer disk, or are similarly maintained,
  and the Fund shall reimburse the Custodian for its expenses of providing such
  hard copy or microfilm.

         13. The Custodian shall provide the Fund with any report obtained by
  the Custodian on the system of internal accounting control of the Book-Entry
  System, the Depository or O.C.C., and with such reports on its own systems of
  internal accounting control as the Fund may reasonably request from time to
  time.

         14. The Fund agrees to indemnify the Custodian against and save the
  Custodian harmless from all liability, claims, losses and demands whatsoever,
  including attorney's fees, howsoever arising or incurred because of or in
  connection with this Agreement, including the Custodian's payment or
  non-payment of checks pursuant to paragraph 6 of Article XIII as part of any
  check redemption privilege program of the Fund, except for any such liability,
  claim, loss and demand arising out of the Custodian's own negligence or
  willful misconduct.

         15. Subject to the foregoing provisions of this Agreement, including,
  without limitation, those contained in Article XVI and XVII the Custodian may
  deliver and receive Securities, and receipts with respect to such Securities,
  and arrange for payments to be made and received by the Custodian in
  accordance with the customs prevailing from time to time among brokers or
  dealers in such Securities. When the Custodian is instructed to deliver
  Securities against payment, delivery of such Securities and receipt of payment
  therefor may not be completed simultaneously. The Fund assumes all
  responsibility and liability for all credit risks involved in connection with
  the Custodian's delivery of Securities pursuant to instructions of the Fund,
  which responsibility and liability shall continue until final payment in full
  has been received by the Custodian.

         16. The Custodian shall have no duties or responsibilities whatsoever
  except such duties and responsibilities as are specifically set forth in this
  Agreement, and no covenant or obligation shall be implied in this Agreement
  against the Custodian.

                                 ARTICLE XIX.

                                  TERMINATION

         1. Either of the parties hereto may terminate this Agreement by giving
  to the other party a notice in writing

                                      -38-
<PAGE>
 
  specifying the date of such termination, which shall be not less than ninety
  (90) days after the date of giving of such notice. In the event such notice is
  given by the Fund, it shall be accompanied by a copy of a resolution of the
  Board of Directors of the Fund, certified by the Secretary or any Assistant
  Secretary, electing to terminate this Agreement and designating a successor
  custodian or custodians, each of which shall be a bank or trust company having
  not less than $2,000,000 aggregate capital, surplus and undivided profits.
  In the event such notice is given by the Custodian, the Fund shall, on or
  before the termination date, deliver to the Custodian a copy of a resolution
  of the Board of Directors of the Fund, certified by the Secretary or any
  Assistant Secretary, designating a successor custodian or custodians.
  In the absence of such designation by the Fund, the Custodian may designate a
  successor custodian which shall be a bank or trust company having not less

  (e)     A Specimen Share certificate for each class of Shares in the form
          approved by the Board of Directors of the Customer, together with a

          approval and covenanting to supply a new such Certificate and specimen
          whenever such form shall change;

          applicable law or regulation (i.e., if subject to registration, that
                                        ----

     3.   The Customer shall furnish the Bank with a sufficient supply of blank
Share certificates and from time to time will renew such supply upon request of

                                  ARTICLE III

  (b)     An opinion of counsel for the Customer, in a form satisfactory to the
          Bank, with respect to the validity of the Shares, the obtaining of all

          Act of 1933, as amended, and any other applicable federal law or
          regulations (i.e., if subject to registration, that they have been
                       -----
          registered and that the Registration Statement has become effective 
          or, if exempt, the specific grounds therefor); and

  (c)     In the case of an increase, if the appointment of the Bank was
          theretofore expressly limited, a certified copy of a resolution of the
          Board of Directors of the Customer increasing the authority of the
          Bank.

    2.    Prior to the issuance of any additional Shares pursuant to stock

of Shares outstanding, the Customer shall deliver the following documents to the
Bank:

  (a)     A certified copy of the resolutions adopted by the Board of Directors
          and/or the shareholders of the Customer authorizing such issuance of
          additional Shares of the Customer or such reduction, as the case may
          be;

  (b)     A certified copy of the order or consent of each governmental or
          regulatory authority required by law as a prerequisite to the issuance
          or reduction of such Shares, as the case may be, and an opinion of
          counsel for the Customer that no other order or consent is required;
          and

  (c)     An opinion of counsel for the Customer, in a form satisfactory to the

          and non-assessable and the status of such Shares under the Securities
          Act of 1933, as amended, and any other applicable law or regulation
          (i.e., if subject to registration, that they have been registered and
           -----

          the specific grounds therefor).

                                   ARTICLE IV
                     RECAPITALIZATION OR CAPITAL ADJUSTMENT
                     --------------------------------------

     1.   In the case of any negative stock split, recapitalization or other
capital adjustment requiring a change in the form of Share certificates, the
Bank will issue Share certificates in the new form in exchange for, or upon
transfer of, outstanding Share certificates in the old form, upon receiving:

          the new form;

  (b)     A certified copy of any amendment to the Charter with respect to
          the change;

  (c)     Specimen Share certificates for each class of Shares in the new form
          approved by the Board of Directors of the Customer, with a Certificate
          signed by the Secretary of the Customer as to such approval;
<PAGE>
 
                                      -4-


  (d)     A certified copy of the order or consent of each governmental or
          regulatory authority required by law as a prerequisite to the issuance
          of the Shares in the new form, and an opinion of counsel for the
          Customer that the order or consent of no other governmental or
          regulatory authority is required; and

  (e)     An opinion of counsel for the Customer, in a form satisfactory to the
          Bank, with respect to the validity of the Shares in the new form, the
          obtaining of all necessary governmental consents, whether such Shares
          are fully paid and non-assessable and the status of such Shares
          under the Securities Act of 1933, as amended, and any other applicable
          law or regulation (i.e., if subject to registration, that the Shares
                             -----
          have been registered and that the Registration Statement has become
          effective or, if exempt, the specific grounds therefore).

     2.   The Customer shall furnish the Bank with a sufficient supply of blank
Share certificates in the new form, and from time to time will replenish such
supply upon the request of the Bank. Such blank Share certificates shall be
properly signed, by facsimile or otherwise, by Officers of the Customer
authorized by law or by the By-Laws to sign Share certificates and, if required,
shall bear the corporate seal or a facsimile thereof.

                                   ARTICLE V
                        ISSUANCE AND TRANSFER OF SHARES
                        -------------------------------

     1.   The Bank will issue Share certificates upon receipt of a Certificate
from an Officer, but shall not be required to issue Share certificates after it
has received from an appropriate federal or state authority written notification
that the sale of Shares has been suspended or discontinued, and the Bank shall
be entitled to rely upon such written notification. The Bank shall not be
responsible for the payment of any original issue or other taxes required to be
paid by the Customer in connection with the issuance of any Shares.

     2. Shares will be transferred upon presentation to the Bank of Share
certificates in form deemed by the Bank properly endorsed for transfer,
accompanied by such documents as the Bank deems necessary to evidence the
authority of the person making such transfer, and bearing satisfactory evidence
of the payment of applicable stock transfer taxes. In the case of small estates
where no administration is contemplated, the Bank may, when furnished with an
appropriate surety bond, and without further approval of the Customer, transfer
Shares registered in the name of the decedents where the current market value of
the Shares being transferred does not exceed such amount as may from time to
time be prescribed by the various states. The Bank reserves the right to refuse
to transfer Shares until it is satisfied that the endorsements on Share
certificates are valid and genuine, and for that purpose it may require, unless
otherwise instructed by an Officer of the Customer, a guaranty of signature by
an "eligible guarantor institution" meeting the requirements of the Bank, which
requirements include membership or participation in STAMP or such other
"signature guarantee program" as may be determined by the Bank in addition to,
or in substitution for, STAMP, all in accordance with the Securities Exchange
Act of 1934, as amended. The Bank also reserves the right to refuse to transfer
Shares until it is satisfied that the requested transfer is legally authorized,
and it shall incur no liability for the refusal in good faith to make transfers
which the Bank, in its judgment, deems improper or unauthorized, or until it is
satisfied that there is no basis to any claims adverse to such transfer. The
Bank may, in effecting transfers of Shares, rely upon those provisions of the
Uniform Act for the Simplification of Fiduciary Security Transfers or the
Uniform Commercial Code, as the same may be amended from time to time,
applicable to the transfer of securities, and the Customer shall indemnify the
Bank for any act done or omitted by it in good faith in reliance upon such laws.

                                      -5-


     3.   All certificates representing Shares that are subject to restrictions
on transfer (e.g., securities acquired pursuant to an investment representation,
             ----                                                              
securities held by controlling person, securities subject to stockholders'
agreement, etc.), shall be stamped with a legend describing the extent and
conditions of the restrictions or referring to the source of such restrictions.
The Bank assumes no responsibility with respect to the transfer of restricted
securities where counsel for the Customer advises that such transfer may be
properly effected.

     4.   Notwithstanding the foregoing or any other provision contained in this
Agreement to the contrary, the Bank shall be fully protected by the Customer in
not requiring any instruments, documents, assurances, endorsements or
guarantees, including, without limitation, any signature guarantees, in
connection with a transfer of Shares whenever the Bank reasonably believes that
requiring the same would be inconsistent with the transfer procedures as
described in the Prospectus.

                                   ARTICLE VI
                           DIVIDENDS AND DISTRIBUTIONS
                           ---------------------------

     1.   The Customer shall furnish to the Bank a copy of a resolution of its
Board of Directors, certified by the Secretary or any Assistant Secretary,
either (i) setting forth the date of the declaration of a dividend or
distribution, the date of accrual or payment, as the case may be, the record
date as of which shareholders entitled to payment, or accrual, as the case may
be shall be determined, the amount per Share of such dividend or distribution,
the payment date on which all previously accrued and unpaid dividends are to be
paid, and the total amount, if any, payable to the Bank on such payment date, or
(ii) authorizing the declaration of dividends and distributions on a periodic
basis and authorizing the Bank to rely on a Certificate setting forth the
information described in subsection (i) of this paragraph.

     2.   Prior to the payment date specified in such Certificate or resolution,
as the case may be, the Customer shall, in the case of a cash dividend or
distribution, pay to the Bank an amount of cash, sufficient for the Bank to make
the payment, specified in such Certificate or resolution, to the shareholders of
record as of such payment date. The Bank will, upon receipt of any such cash,
(i) in the case of shareholders who are participants in a dividend reinvestment
and/or cash purchase plan of the Customer, reinvest such cash dividends or
distributions in accordance with the terms of such plan, and (ii) in the case of
shareholders who are not participants in any such plan, make payment of such
cash dividends or distributions to the shareholders of record as of the record
date by mailing a check, payable to the registered shareholder, to the address
of record or dividend mailing address. The Bank shall not be liable for any
improper payment made in accordance with a Certificate or resolution described
in the preceding paragraph.  If the Bank shall not receive sufficient cash prior
to the payment date to make payments of any cash dividend or distribution
pursuant to subsections (i) and (ii) above to all shareholders of the Customer
as of the record date, the Bank shall, upon notifying the Customer, withhold
payment to all shareholders of the Customer as of the record date until
sufficient cash is provided to the Bank.

     3.   It is understood that the Bank shall in no way be responsible for the
determination of the rate or form of dividends or distributions due to the
shareholders.

     4.   It is understood that the Bank shall file such appropriate information
returns concerning the payment of dividends and distributions with the proper
federal, state and local authorities as are required by law to be filed by the
Customer but shall in no way be responsible for the collection or withholding of
taxes due on such dividends or distributions due to shareholders, except and
only to the extent required of it by applicable law.

                                  ARTICLE VII
                            CONCERNING THE CUSTOMER
                            -----------------------

     1.   The Customer shall promptly deliver to the Bank written notice of any
change in the Officers authorized to sign Share certificates, Certificates,
notifications or requests, together with a specimen signature of each new
Officer. In the event any Officer who shall have signed manually or whose
facsimile signature shall have been affixed to blank Share certificates shall
die, resign or be removed prior to issuance of such Share certificates, the Bank
may issue such Share certificates as the Share certificates of the Customer
notwithstanding such death, resignation or removal, and the Customer shall
promptly deliver to the Bank such approvals, adoptions or ratifications as may
be required by law.

     2.   Each copy of the Charter of the Customer and copies of all amendments
thereto shall be certified by the Secretary of State (or other appropriate
official) of the state of incorporation, and if such Charter and/or amendments
are required by law also to be filed with a county or other officer or official
body, a certificate of such filing shall be filed with a certified copy
submitted to the Bank.  Each copy of the By-Laws and copies of all amendments
thereto, and copies of resolutions of the Board of Directors of the Customer,
shall be certified by the Secretary or an Assistant Secretary of the Customer
under the corporate seal.

     3.   Customer hereby represents and warrants:

     (a)  It is a corporation duly organized and validly existing under the laws
          of Maryland.

     (b)  This Agreement has been duly authorized, executed and delivered on its
          behalf and constitutes the legal, valid and binding obligation of
          Customer. The execution, delivery and performance of this Agreement by
          Customer do not and will not violate any applicable law or regulation
          and do not require the consent of any governmental or other regulatory
          body except for such consents and approvals as have been obtained and
          are in full force and effect.

     4.   It shall be the sole responsibility of the Customer to deliver to the
          Bank the Customer's currently effective Prospectus and, for purposes
          of this Agreement, the Bank shall not be deemed to have notice of any
          information contained in such Prospectus until it is actually received
          by the Bank.

                                  ARTICLE VIII
                              CONCERNING THE BANK
                              -------------------

     1.   The Bank shall not be liable and shall be fully protected in acting
upon any oral instruction, writing or document reasonably believed by it to be
genuine and to have been given, signed or made by the proper person or persons
and shall not be held to have any notice of any change of authority of any
person until receipt of written notice thereof from an Officer of the Customer.
It shall also be protected in processing Share certificates which it reasonably
believes to bear the proper manual or facsimile signatures of the duly
authorized Officer or Officers of the Customer and the proper countersignature
of the Bank.

     2.   The Bank may establish such additional procedures, rules and
regulations governing the transfer or registration of Share certificates as
it may deem advisable and consistent with such rules and regulations generally
adopted by bank transfer agents.
<PAGE>
 
                                      -7-


     3.   The Bank may keep such records as it deems advisable but not
inconsistent with resolutions adopted by the Board of Directors of the Customer.
The Bank may deliver to the Customer from time to time at its discretion, for
safekeeping or disposition by the Customer in accordance with law, such records,
papers, Share certificates which have been cancelled in transfer or exchange and
other documents accumulated in the execution of its duties hereunder as the Bank
may deem expedient, other than those which the Bank is itself required to
maintain pursuant to applicable laws and regulations, and the Customer shall
assume all responsibility for any failure thereafter to produce any record,
paper, cancelled Share certificate or other document so returned, if and when
required. The records maintained by the Bank pursuant to this paragraph which
have not been previously delivered to the Customer pursuant to the foregoing
provisions of this paragraph shall be considered to be the property of the
Customer, shall be made available upon request for inspection by the Officers,
employees and auditors of the Customer, and shall be delivered to the Customer
upon request and in any event upon the date of termination of this Agreement, as
specified in Article IX of this Agreement, in the form and manner kept by the
Bank on such date of termination or such earlier date as may be requested by the
Customer.

     4.   The Bank may employ agents or attorneys-in-fact at the expense of the
Customer, and shall not be liable for any loss or expense arising out of, or in
connection with, the actions or omissions to act of its agents or attorneys-in-
fact, so long as the Bank acts in good faith and without negligence or willful
misconduct in connection with the selection of such agents or attorneys-in-fact.

     5.   The Bank shall only be liable for any loss or damage arising out of
its own negligence or willful misconduct; provided, however, that the Bank shall
not be liable for any indirect, special, punitive or consequential damages.

     6. The Customer shall indemnify and hold harmless the Bank from and against
any and all claims (whether with or without basis in fact or law), costs,
demands, expenses and liabilities, including reasonable attorney's fees, which
the Bank may sustain or incur or which may be asserted against the Bank except
for any liability which the Bank has assumed pursuant to the immediately
preceding section. The Bank shall be deemed not to have acted with negligence
and not to have engaged in willful misconduct by reason of or as a result of any
action taken or omitted to be taken by the Bank without its own negligence or
willful misconduct in reliance upon (i) any provision of this Agreement, (ii)
any instrument, order or Share certificate reasonably believed by it to be
genuine and to be signed, countersigned or executed by any duly authorized
Officer of the Customer, (iii) any Certificate or other instructions of an
Officer, (iv) any opinion of legal counsel for the Customer or the Bank, or (v)
any law, act, regulation or any interpretation of the same even though such law,
act, or regulation may thereafter have been altered, changed, amended or
repealed. Nothing contained herein shall limit or in any way impair the right of
the Bank to indemnification under any other provision of this Agreement.

     7.   Specifically, but not by way of limitation, the Customer shall
indemnify and hold harmless the Bank from and against any and all claims
(whether with or without basis in fact or law), costs, demands, expenses and
liabilities, including reasonable attorney's fees, of any and every nature which
the Bank may sustain or incur or which may be asserted against the Bank in
connection with the genuineness of a Share certificate, the Bank's due
authorization by the Customer to issue Shares and the form and amount of
authorized Shares.

                                      -8-



     8.   At any time the bank may apply to an Officer of the Customer for
written instructions with respect to any matter arising in connection with the
Bank's duties and obligations under this Agreement, and the Bank shall not be
liable for any action taken or omitted to be taken by the Bank in good faith in
accordance with such instructions. Such application by the Bank for instructions
from an Officer of the Customer may, at the option of the Bank, set forth in
writing any action proposed to be taken or omitted to be taken by the Bank with
respect to its duties or obligations under this Agreement and the date on and/or
after which such action shall be taken, and the Bank shall not be liable for any
action taken or omitted to be taken in accordance with a proposal included in
any such application on or after the date specified therein unless, prior to
taking or omitting to take any such action, the Bank has received written
instructions in response to such application specifying the action to be taken
or omitted. The Bank may consult counsel to the Customer or its own counsel, at
the expense of the Customer, and shall be fully protected with respect to
anything done or omitted by it in good faith in accordance with the advice or
opinion of such counsel.

     9.   When mail is used for delivery of non-negotiable Share certificates,
the value of which does not exceed the limits of the Bank's Blanket Bond, the
Bank shall send such non-negotiable Share certificates by first class mail, and
such deliveries will be covered while in transit by the Bank's Blanket Bond.
Non-negotiable Share certificates, the value of which exceed the limits of the
Bank's Blanket Bond, will be sent by insured registered mail. Negotiable Share
certificates will be sent by insured registered mail. The Bank shall advise the
Customer of any Share certificates returned as undeliverable after being mailed
as herein provided for.

     10.  The Bank may issue new Share certificates in place of Share
certificates represented to have been lost, stolen or destroyed upon receiving
instructions in writing from an Officer and indemnity satisfactory to the Bank.
Such instructions from the Customer shall be in such form as approved by the
Board of Directors of the Customer in accordance with applicable law or the By-
Laws of the Customer governing such matters. If the Bank receives written
notification from the owner of the lost, stolen or destroyed Share certificate
within a reasonable time after he has notice of it, the Bank shall promptly
notify the Customer and shall act pursuant to written instructions signed by an
Officer. If the Customer receives such written notification from the owner of
the lost, stolen or destroyed Share certificate within a reasonable time after
he has notice of it, the Customer shall promptly notify the Bank and the Bank
shall act pursuant to written instructions signed by an Officer. The Bank shall
not be liable for any act done or omitted by it pursuant to the written
instructions described herein. The Bank may issue new Share certificates in
exchange for, and upon surrender of, mutilated Share certificates .

     11.  The Bank will issue and mail subscription warrants for Shares, Shares
representing stock dividends, exchanges or splits, or act as conversion agent
upon receiving written instructions from an Officer and such other documents as
the Bank may deem necessary.

     12.  The Bank will supply shareholder lists to the Customer from time to
time upon receiving a request therefor from an Officer of the Customer.

     13.  In case of any requests or demands for the inspection of the
shareholder records of the Customer, the Bank will notify the Customer and
endeavor to secure instructions from an Officer as to such inspection.  The Bank
reserves the right, however, to exhibit the shareholder record to any person
whenever it is advised by its counsel that there is a reasonable likelihood that
the Bank will be held liable for the failure to exhibit the shareholder records
to such person.

    14.   At the request of an Officer, the Bank will address and mail such
appropriate notices to shareholders as the Customer may direct.

    15.   Notwithstanding any provisions of this Agreement to the contrary, the
Bank shall be under no duty or obligation to inquire into, and shall not be
liable for:
<PAGE>
 
                                      -9-


  (a)     The legality of the issue, sale or transfer of any Shares, the
          sufficiency of the amount to be received in connection therewith, or
          the authority of the Customer to request such issuance, sale or
          transfer;

  (b)     The legality of the purchase of any Shares, the sufficiency of the
          amount to be paid in connection therewith, or the authority of the
          Customer to request such purchase;

  (c)     The legality of the declaration of any dividend by the Customer, or
          the legality of the issue of any Shares in payment of any stock
          dividend; or

  (d)     The legality of any recapitalization or readjustment of the Shares.

     16.  The Bank shall be entitled to receive and the Customer hereby agrees
to pay to the Bank for its performance hereunder (i) out-of-pocket expenses
(including legal expenses and attorney's fees) incurred in connection with this
Agreement and its performance hereunder, and (ii) the compensation for services
as set forth in Schedule I.

     17.  The Bank shall not be responsible for any money, whether or not
represented by any check, draft or other instrument for the payment of money,
received by it on behalf of the Customer, until the Bank actually receives and
collects such funds.

     18.  The Bank shall have no duties or responsibilities whatsoever except
such duties and responsibilities as are specifically set forth in this
Agreement, and no covenant or obligation shall be implied against the Bank in
connection with this Agreement.


                                   ARTICLE IX
                                  TERMINATION
                                  -----------

     Either of the parties hereto may terminate this Agreement by giving to the
other party a notice in writing specifying the date of such termination, which
shall be not less than 60 days after the date of receipt of such notice. In the
event such notice is given by the Customer, it shall be accompanied by a copy of
a resolution of the Board of Directors of the Customer, certified by the

transfer agent or transfer agents. In the event such notice is given by the

agent.  If the Customer fails to designate a successor Transfer agent and if the
Bank is unable to find a successor transfer agent, the Customer shall, upon the
date specified in the notice of termination of this Agreement and delivery of
the records maintained hereunder, be deemed to be its own transfer agent and the
Bank shall thereafter be relieved of all duties and responsibilities hereunder.
Upon termination hereof, the Customer shall pay to the Bank such compensation as
may be due to the Bank for any disbursements and expenses made or incurred by
the Bank and payable or reimbursable hereunder.
