Key Facts [KEY FACTS ICON]

IN AN EFFORT TO HELP YOU BETTER UNDERSTAND THE MANY CONCEPTS INVOLVED IN MAKING
AN INVESTMENT DECISION, WE HAVE DEFINED THE HIGHLIGHTED TERMS IN THIS PROSPECTUS
IN THE SIDEBAR.

TOTAL RETURN -- the combination of capital appreciation and investment income.

   
CONVERTIBLE SECURITY -- a fixed income security such as a bond or preferred
stock that is exchangeable for shares of common stock of the issuer or of
another company.
    

   
SYNTHETIC CONVERTIBLE SECURITY -- a convertible security created by Fund
management by combining two or more separate securities. This may also be a
security for which the holder receives a cash payment instead of receiving
common stock upon conversion.
    
 
   
THE MERRILL LYNCH CONVERTIBLE FUND AT A GLANCE
    
- --------------------------------------------------------------------------------

   
WHAT ARE THE FUND'S OBJECTIVE AND GOALS?
    
 
   
The investment objective of the Fund is to seek high TOTAL RETURN from a
combination of capital appreciation and investment income.
    
 
WHAT ARE THE FUND'S MAIN INVESTMENT STRATEGIES?
 
   
The Fund invests primarily in a portfolio of CONVERTIBLE SECURITIES and
SYNTHETIC CONVERTIBLE SECURITIES. These convertible securities may be either
convertible debt securities or convertible preferred stocks and may be issued by
both U.S. and foreign issuers. Under normal market conditions, the Fund invests
at least 65% of its total assets in convertible securities and synthetic
convertibles.
    

   
A substantial portion of the Fund's assets may at times be invested in foreign
securities. The Fund may invest in high yield or "junk" bonds, in certain types
of derivative securities and in illiquid securities.
    

   
When choosing investments Fund management attempts to identify securities issued
by companies that it believes are creditworthy and that either have high current
yields, a high potential for capital appreciation because the underlying common
stock is undervalued, or both. Fund management will find an issuer to be
creditworthy when it believes the issuer can make timely payments of interest
and principal. In evaluating an investment, Fund management will also take into
account a security's maturity and call features. The Fund is nondiversified,
which means that it is able to invest more of its assets in fewer companies than
if it were a diversified fund. We cannot guarantee that the Fund will achieve
its goal.
    

WHAT ARE THE MAIN RISKS OF INVESTING IN THE FUND?

   
As with any mutual fund, the value of the Fund's investments -- and therefore
the value of Fund shares -- may go up or down. These changes may occur because
the stock market is rising or falling. These changes also may occur in response
to interest rate changes. Generally, when interest rates go up, the value of a
convertible goes down. At other times, there are specific factors that may
affect the value of a particular investment. If the value of the Fund's
investments goes down, you may lose money.
    
 
   
Derivatives and high yield or "junk" bonds may be volatile and subject to
liquidity, leverage, credit and other types of risks.

[KEY FACTS ICON] Key Facts
 
   
A convertible security may lose all or a significant portion of its value if the
value of the underlying security falls below the exercise price.
    
 
   
Foreign investing involves special risks -- including foreign currency risk and
the possibility of substantial volatility due to adverse political, economic or
other developments. Foreign securities may be less liquid and harder to value
than U.S. securities.
    
 
   
As a nondiversified fund, the Fund may concentrate in a smaller number of
investments, which increases the Fund's risk because each investment has a
greater effect on the Fund's performance.
    
 
   
WHO SHOULD INVEST?
    
 
The Fund may be an appropriate investment for you if you:
 
   
       - Are investing with long term goals, such as retirement or
         funding a child's education, but also seek current income;
    
 
       - Want to diversify your portfolio;
 
       - Want a professionally managed portfolio without the administrative
         burdens of direct investments in convertible securities.

RISK/RETURN BAR CHART
- --------------------------------------------------------------------------------
 
   
The bar chart and table shown below provide an indication of the risks of
investing in the Fund. The bar chart shows changes in the Fund's performance for
Class A shares from year to year for the ten year period. Prior to August 4,
1997 the Fund operated as a dual purpose closed end investment company with
different investment objectives and policies from the Fund's current objectives
and policies. Sales charges are not reflected in the bar chart. If these amounts
were reflected, returns would be less than those shown. The table compares the
average annual total returns for the Fund's Class A shares for one, five and ten
years with those of the Value Line Convertible Index for the same periods. The
average annual total returns for the Fund's Class B, Class C and Class D shares
are not provided. These classes commenced operations on August 4, 1997 and as of
December 31, 1997 a full calendar year of information is not available. How the
Fund performed in the past is not necessarily an indication of how the Fund will
perform in the future.

UNDERSTANDING EXPENSES

Fund investors pay various fees and expenses, either directly or indirectly.

SHAREHOLDER FEES -- these include sales charges which you may pay when you buy
or sell shares of the Fund.

FEES AND EXPENSES
- --------------------------------------------------------------------------------
 
The Fund offers four different classes of shares. Although your money will be
invested the same way no matter which class of shares you buy, there are
differences among the fees and expenses associated with each class. Not everyone
is eligible to buy every class. After determining which classes you are eligible
to buy, decide which class best suits your needs. Your Merrill Lynch Financial
Consultant can help you with this decision.
 
This table shows the different fees and expenses that you may pay if you buy and
hold the different classes of shares of the Fund. Future expenses may be greater
or less than those indicated below.

(a) Class B shares automatically convert to Class D shares about eight years
    after you buy them. Then they will no longer be subject to distribution
    fees.
 
(b) Some investors may qualify for reductions in the sales charge (load).

(c) You may pay a deferred sales charge if you purchase $1 million or more and
    you redeem within one year.
 
   
(d) The Fund pays the Manager a fee at the annual rate of 0.60% of the average
    daily net assets of the Fund.
    

   
(e) The Fund calls the "Service Fee" an "Account Maintenance Fee." Account
    Maintenance Fee is the term used elsewhere in this Prospectus and all other
    Fund materials. If you hold Class B or Class C shares for a long time, it
    may cost you more in distribution (12b-1) fees than the maximum sales charge
    that you would have paid if you had bought one of the other classes.
    

   
(f) The Fund pays the Transfer Agent $11.00 for each Class A and Class D
    shareholder account and $14.00 for each Class B and Class C shareholder
    account and reimburses the Transfer Agent's out-of-pocket expenses. The Fund
    pays a 0.10% fee for certain accounts that participate in the Merrill Lynch
    Mutual Fund Advisor program. The Fund also pays a $0.20 monthly closed
    account charge, which is assessed upon all accounts that close during the
    year. This fee begins the month following the month the account is closed
    and ends at the end of the calendar year. For the fiscal year ended August
    31, 1998, the Fund paid the Transfer Agent fees totaling $94,488. The
    Manager provides accounting services to the Fund at its cost. For the fiscal
    year ended August 31, 1998, the Fund reimbursed the Manager $106,046 for
    these services.
    
 
(g) In addition, Merrill Lynch may charge clients a processing fee (currently
    $5.35) when a client buys or redeems shares.

EXAMPLES:
 
These examples are intended to help you compare the cost of investing in the
Fund with the cost of investing in other mutual funds.
 
These examples assume that you invest $10,000 in the Fund for the time periods
indicated, that your investment has a 5% return each year, that you pay the
sales charges, if any, that apply to the particular class and that the Fund's
operating expenses remain the same. This assumption is not meant to indicate you
will receive a 5% annual rate of return. Your annual return may be more or less
than the 5% used in this example. Although your actual costs may be higher or
lower, based on these assumptions your costs would be:

Details About the Fund [DETAILS ABOUT THE FUND ICON]

ABOUT THE PORTFOLIO MANAGER
 
Daniel A. Luchansky is the portfolio manager of the Fund. Mr. Luchansky has been
the portfolio manager of the Fund since 1995 and has been a Vice President of
Merrill Lynch Asset Management since 1991.

ABOUT THE MANAGER

The Fund is managed by Merrill Lynch Asset Management.

HOW THE FUND INVESTS
- --------------------------------------------------------------------------------
 
The Fund's main goal is to seek high total return from a combination of capital
appreciation and investment income. The Fund invests primarily in a portfolio of
convertible debt securities, convertible preferred stocks and synthetic
convertible securities. These securities may be issued by both U.S. and foreign
issuers. Under normal market conditions, the Fund invests at
least 65% of its total assets in convertible securities and synthetic
convertibles.
 
   
Convertible securities are fixed income securities, such as debt and preferred
stock, that allow the holder to convert the security into shares of common
stock. The terms of each convertible security contain a conversion formula (the
amount of the fixed income security that must be surrendered to acquire a share
of common stock), and may also limit the right to convert to certain time
periods or circumstances. The common stock that can be acquired upon conversion
may be issued by the same company that issued the convertible fixed income
security, or may be issued by a different company. Synthetic convertible
securities are similar but may be assembled by the Manager from separately
issued fixed income and equity linked securities.
    
 
   
Convertibles typically pay current income, as either interest on bonds or
dividends on preferred stocks. The market values a convertible in part on this
stream of current income payments and in part on the value of the underlying
common stock. The value of a convertible may react to interest rates in the same
way as a nonconvertible debt security: if market interest rates rise, the value
of a convertible usually falls. In addition, the convertible
has the same types of market and issuer risk as the underlying common stock.
    
 
   
Convertible securities can provide high total return from a combination of
capital appreciation and investment income. If the value of the underlying
common stock increases, the value of the convertible security also increases.
The dividend or interest payments on the convertible security are likely to be
higher than dividends paid on common stock though they will be lower than
similar payments on nonconvertible debt obligations or preferred stocks.

MATURITY -- the time at which the principal amount of a bond is scheduled to be
returned to investors.

CALL FEATURE -- the right of an issuer to repay the principal amount of a bond
prior to maturity.

SHORT SALE -- a sale of securities borrowed from others with the expectation
that the price of the security will fall before the Fund must purchase the
security to return it to the lender.
 
   
HEDGE -- an investment technique involving the purchase or short sale of an
asset in the expectation that any gains will offset losses experienced on other
holdings, or vice versa.
    
 
   
Fund management selects convertible securities by considering various factors
including:
    
 
   
       - Yield on the convertible security relative to its credit
         quality.
    
 
   
       - The potential capital appreciation offered by the underlying
         common stock.
    
 
   
       - The MATURITY and CALL FEATURES of these securities.
    
 
   
The Fund may invest in "junk" bonds. Junk bonds are bonds that are rated below
investment grade by independent rating agencies or are bonds that are not rated
but which Fund management considers to be of comparable quality.
    
 
   
The Fund may invest up to 35% of its total assets in assets other than
convertible securities and synthetic convertible securities. These other assets
may include common stock, nonconvertible preferred stock, options, warrants and
nonconvertible debt securities of U.S. or foreign issuers.
    
 
   
The Fund may also invest in money market securities of U.S. and foreign issuers,
or cash.
    
 
The Fund may invest in derivatives and may SELL SECURITIES SHORT as a HEDGE or
to increase total returns. In addition, the Fund may invest up to 15% of its net
assets in securities that lack an established secondary trading market or
otherwise are considered illiquid.

   
INVESTMENT RISKS
    
- --------------------------------------------------------------------------------

   
This section contains a summary discussion of the general risks of investing in
the Fund. As with any mutual fund, there can be no guarantee that the Fund will
meet its goals or that the Fund's performance will be positive for any period of
time.

MARKET AND SELECTION RISK -- Market risk is the risk that the stock or bond
markets will go up or down in value, including the possibility that the markets
will go down sharply and unpredictably. Selection risk is the risk that the
investments that Fund management selects will underperform the market or other
funds with similar investment objectives and investment strategies.

<PAGE>   11
[DETAILS ABOUT THE FUND ICON] Details About the Fund
 
   
CREDIT RISK -- 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.
    
 
   
INTEREST RATE RISK -- Interest rate risk is the risk that prices of fixed income
securities 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.
    
 
   
FOREIGN MARKET RISK -- Since the Fund may invest in foreign securities, it
offers the potential for more diversification than an investment only in the
United States. This is because securities traded on foreign markets have often
(though not always) performed differently than securities in the United States.
However, these investments involve special risks not present in U.S. investments
that can increase the chances that the Fund will lose money. In particular,
investment in foreign securities involves the following risks, which are
generally greater for investments in emerging markets:
    
 
   
       - The economies of some foreign markets often do not compare
         favorably with that of the United States in areas such as growth
         of gross domestic product, reinvestment of capital, resources,
         and balance of payments. Some of these economies may rely
         heavily on particular industries or foreign capital. They may be
         more vulnerable to adverse diplomatic developments, the
         imposition of economic sanctions against a particular country or
         countries, changes in international trading patterns, trade
         barriers and other protectionist or retaliatory measures.
    
 
   
       - Investments in foreign markets may be adversely affected by
         governmental actions such as the imposition of capital controls,
         nationalization of companies or industries, expropriation of
         assets or the imposition of punitive taxes.
    
 
   
       - The governments of certain countries may prohibit or impose
         substantial restrictions on foreign investing in their capital
         markets or in certain industries. Any of these actions could
         severely affect security prices. They could also impair the
         Fund's ability to purchase or sell foreign securities or
         transfer its assets or income back into the United States, or
         otherwise adversely affect the Fund's operations.

<PAGE>   12
 
   
       - Other foreign market risks include foreign exchange controls,
         difficulties in pricing securities, defaults on foreign
         government securities, difficulties in enforcing favorable legal
         judgments in foreign courts and political and social
         instability. Legal remedies available to investors in some
         foreign countries may be less extensive than those available to
         investors in the United States.
    
 
   
       - Because there are generally fewer investors on foreign exchanges
         and a smaller number of securities traded each day, it may be
         difficult for the Fund to buy and sell securities on those
         exchanges. In addition, prices of foreign securities may go up
         or down more than prices of securities traded in the United
         States.
    
 
   
       - Foreign markets have different clearance and settlement
         procedures. In certain markets, settlements may be unable to
         keep pace with the volume of securities transactions. If this
         occurs, settlement may be delayed and the Fund's assets may be
         uninvested and not earning returns. The Fund also may miss
         investment opportunities or be unable to sell an investment
         because of these delays.
    
 
   
EUROPEAN ECONOMIC AND MONETARY UNION (EMU) -- A number of European countries
have agreed to enter into EMU in an effort to reduce trade barriers between
themselves and eliminate fluctuations in their currencies. EMU establishes a
single European currency (the euro), which will be introduced on January 1, 1999
and is expected to replace the existing national currencies of all initial EMU
participants by July 1, 2002. Upon introduction of the euro, certain securities
(beginning with government and corporate bonds) will be redenominated in the
euro. Thereafter, these securities will trade and make dividend and other
payments only in euros. Like other investment companies and business
organizations, including the companies in which the Fund invests, the Fund could
be adversely affected:
    
 
   
       - If the euro, or EMU as a whole, does not take effect as planned.
    
 
   
       - If a participating country withdraws from EMU.

[DETAILS ABOUT THE FUND ICON] Details About the Fund
 
   
       - If the computing, accounting and trading systems used by the
         Fund's service providers, or by other entities with which the
         Fund or its service providers do business, are not capable of
         recognizing the euro as a distinct currency beginning with euro
         conversion.
    
 
Risks associated with certain types of securities in which the Fund may invest
include:
 
   
JUNK BONDS -- The Fund may buy convertible and non-convertible debt securities
that are low grade, including "junk bonds." There is no minimum rating for
securities in which the Fund may invest. Convertible junk bonds, like other junk
bonds, have a higher chance that the issuer will default on interest or
principal payments. Junk bonds are debt securities that are rated below
investment grade by the major rating agencies or are unrated securities that
Fund management believes are of comparable quality. Although junk bonds
generally pay higher rates of interest than investment grade bonds, they are
high risk investments that may cause income and principal losses for the Fund.
Junk bonds generally are less liquid and experience more price volatility than
higher rated debt securities. The issuers of junk bonds may have a larger amount
of outstanding debt relative to their assets than issuers of investment grade
bonds. In the event of an issuer's bankruptcy, claims of other creditors may
have priority over the claims of junk bond holders, leaving few or no assets
available to repay junk bond holders. Junk bonds may be subject to greater call
and redemption risk than higher rated debt securities.
    
 
   
OTHER NON-PAYMENT -- An issuer may be more likely to fail to make regular
payments on a convertible than on its other debt because other debt securities
may have a prior claim on the issuer's assets, particularly if the convertible
is preferred stock. Convertibles, however, usually have a claim prior to the
issuer's common stock.
    
 
   
INTERNATIONAL CURRENCY -- The securities in which the Fund invests carry
international investment risks if the security is issued by a foreign company
and carry currency risk if the security is denominated in a foreign currency.
The conversion price of a convertible may be based on a currency exchange rate
fixed at the time the convertible was issued, so the movements in the exchange
rates would affect the convertible's value.

<PAGE>   14
WHEN ISSUED SECURITIES -- the purchase of a new security before it has been
issued.
 
FORWARD COMMITMENT -- the purchase of a security for delivery beyond normal 
settlement periods.

CONVERSION, CALL -- For many debt securities, the issuer can choose when to
"call" (redeem) the security. An issuer may call a security at a time that is
disadvantageous to the Fund, and the Fund may be required to reinvest at lower
interest rates, or, in the case of a convertible, convert at an unfavorable
time. Some convertibles may convert only under certain circumstances and carry
the additional risk that conversion may never be permitted.
 
   
SYNTHETICS -- The Fund manager may combine fixed income securities ("fixed
income component") with a right to acquire equities ("convertibility component")
to create "synthetic convertible securities" having economic characteristics of
a true convertible. The components of synthetic convertibles trade separately;
each has its own trading market and value. The value of the synthetic
convertible is the sum of the value of the fixed income and convertibility
components. A synthetic convertible gives the Fund Manager the flexibility to
create an investment that is not directly available in the market. However,
because its components trade separately, often in different markets, the value
of a synthetic convertible may respond differently to market movements and other
events than a traditional convertible. The convertibility component in a
synthetic convertible may be a warrant or option to purchase common stock at a
set price ("exercise price"), or an option on a stock index. If the value of the
underlying common stock or index falls below the exercise price, the warrant or
option may lose all value.
    
 
   
WHEN ISSUED SECURITIES, DELAYED DELIVERY SECURITIES AND FORWARD
COMMITMENTS -- WHEN ISSUED and delayed delivery securities and FORWARD
COMMITMENTS involve the risk that the security the Fund buys will lose value
prior to its delivery. There also is the risk that the security will not be
issued or that the other party will not meet its obligation. If this occurs, the
Fund loses the investment opportunity for the assets it has set aside to pay for
the security and any gain in the security's price.
    
 
   
ILLIQUID INVESTMENTS -- The Fund may invest up to 15% of its assets in illiquid
securities that it cannot easily resell within seven days at current value or
that have contractual or legal restrictions on resale. If the Fund buys illiquid
securities it may be unable to resell them or may be able to sell them only at a
price below current value.

[DETAILS ABOUT THE FUND ICON] Details About the Fund
 
   
DERIVATIVES -- The Fund may use derivative instruments including futures,
forwards, options, indexed securities and inverse securities. Derivatives are
financial instruments whose value is derived from another security, a commodity
(such as oil or gold) or an index such as Value Line Convertible Index.
Derivatives allow the Fund to increase or decrease its risk exposure more
quickly and efficiently than other types of instruments. Derivatives are
volatile and involve significant risks, including:
    
 
   
      Credit risk -- The risk that the counterparty (the party on the
      other side of the transaction) on a derivative transaction will be
      unable to honor its financial obligation to the Fund.
    
 
   
      Leverage risk -- The risk associated with certain types of
      investments or trading strategies (such as borrowing money to
      increase the amount of investments) that relatively small market
      movements may result in large changes in the value of an investment.
      Certain investments or trading strategies that involve leverage can
      result in losses that greatly exceed the amount originally invested.
    
 
   
      Liquidity risk -- The risk that certain securities may be difficult
      or impossible to sell at the time that the seller would like or at
      the price that the seller believes the security is currently worth.
    
 
   
      Currency risk -- The risk that changes in the exchange rate between
      currencies will adversely affect the value (in U.S. dollar terms) of
      an investment.
    
 
   
BORROWING AND LEVERAGE -- The Fund may borrow for temporary emergency purposes
including to meet redemptions. Borrowing may exaggerate changes in the net asset
value of Fund shares and in the yield on the Fund's portfolio. Borrowing will
cost the Fund interest expense and other fees. The cost of borrowing may reduce
the Fund's return. Certain securities that the Fund buys may create leverage
including, for example, when issued securities, forward commitments and options.

MERRILL LYNCH SELECT PRICING(SM) SYSTEM
- --------------------------------------------------------------------------------
 
The Fund offers four share classes, each with its own sales charge and expense
structure, allowing you to invest in the way that best suits your needs. Each
share class represents an ownership interest in the same investment portfolio.
When you choose your class of shares you should consider the size of your
investment and how long you plan to hold your shares. Your Merrill Lynch
Financial Consultant can help you determine which share class is best suited to
your personal financial goals.
 
For example, if you select Class A or D shares, you generally pay a sales charge
at the time of purchase. If you buy Class D shares, you also pay an ongoing
account maintenance fee of 0.25%. You may be eligible for a sales charge waiver.
 
If you select Class B or C shares, you will invest the full amount of your
purchase price, but you will be subject to a distribution fee of 0.75% and an
account maintenance fee of 0.25%. Because these fees are paid out of the Fund's
assets on an ongoing basis, over time these fees increase the cost of your
investment and may cost you more than paying an initial sales charge. In
addition, you may be subject to a deferred sales charge when you sell Class B or
C shares.
 
The Fund's shares are distributed by Merrill Lynch Funds Distributor, a division
of Princeton Funds Distributor, Inc., an affiliate of Merrill Lynch.

 * Rounded to the nearest one-hundredth percent.
 
** If you invest $1,000,000 or more in Class A or Class D shares, you may not
   pay an initial sales charge. However, if you redeem your shares within one
   year after purchase, you may be charged a deferred sales charge. This charge
   is 1% of the lesser of the original cost of the shares being redeemed or your
   redemption proceeds.
 
No initial sales charge applies to Class A or Class D shares that you buy
through reinvestment of dividends or distributions.
 
A reduced or waived sales charge on a purchase of Class A or Class D shares may
apply for:

       - Purchases under a RIGHT OF ACCUMULATION or LETTER OF INTENT.

       - Merrill Lynch Blueprint(SM) Program participants.

       - TMA(SM) Managed Trusts.
 
       - Certain Merrill Lynch investment or central asset accounts.

       - Certain employer-sponsored retirement or savings plans.

       - Purchases using proceeds from the sale of certain Merrill Lynch
         closed-end funds under certain circumstances.

       - Certain investors, including directors or trustees of Merrill
         Lynch mutual funds and Merrill Lynch employees.
 
       - Certain Merrill Lynch fee-based programs.
 
Only certain investors are eligible to buy Class A shares. Your Merrill Lynch
Financial Consultant can help you determine whether you are eligible to buy
Class A shares or to participate in any of these programs.
 
If you decide to buy shares under the initial sales charge alternative and you
are eligible to buy both Class A and Class D shares, you should buy Class A
since Class D shares are subject to a 0.25% account maintenance fee, while Class
A shares are not.
 
If you redeem Class A or Class D shares and within 30 days buy new shares of the
same class, you will not pay a sales charge on the new purchase amount. The
amount eligible for this "Reinstatement Privilege" may not exceed the amount of
your redemption proceeds. To exercise the privilege, contact your Merrill Lynch
Financial Consultant or the Fund's Transfer Agent at 1-800-MER-FUND.
 
CLASS B AND CLASS C SHARES -- DEFERRED SALES CHARGE OPTIONS
 
   
If you select Class B or Class C shares, you do not pay an initial sales charge
at the time of purchase. However, if you redeem your Class B shares within four
years after purchase or your Class C shares within one year after purchase, you
may be required to pay a deferred sales charge. You will also pay distribution
fees of 0.75% and account maintenance fees of 0.25% each year under distribution
plans that the Fund has adopted under Rule 12b-1. Because these fees are paid
out of the Fund's assets on an ongoing basis, over time these fees increase the
cost of your investment and may cost you more than paying an initial sales
charge. The Distributor uses the money that it receives from the deferred sales
charges and the distribution fees to cover the costs of marketing, advertising
and compensating the Merrill Lynch Financial Consultant or other securities
dealer who assists you in purchasing Fund shares.
    
 
Class B Shares
 
If you redeem Class B shares within four years after purchase, you may be
charged a deferred sales charge. The amount of the charge gradually

decreases as you hold your shares over time, according to the following
schedule:

* The percentage charge will apply to the lesser of the original cost of the
  shares being redeemed or the proceeds of your redemption. Shares acquired
  through reinvestment of dividends or distributions are not subject to a
  deferred sales charge. Not all Merrill Lynch funds have identical deferred
  sales charge schedules. If you exchange your shares for shares of another
  fund, the higher charge will apply.
 
   
The deferred sales charge relating to Class B shares may be reduced or waived in
certain circumstances, such as:
    
 
       - Certain post-retirement withdrawals from an IRA or other
         retirement plan if you are over 59 1/2 years old.
 
       - Redemption by certain eligible 401(a) and 401(k) plans and group
         plans participating in the Merrill Lynch Blueprint(SM) Program
         and certain retirement plan rollovers.
 
       - Redemption in connection with participation in certain Merrill
         Lynch fee-based programs.
 
   
       - Withdrawals resulting from shareholder death or disability as
         long as the waiver request is made within one year of death or
         disability or, if later, reasonably promptly following
         completion of probate, or in connection with involuntary
         termination of an account in which Fund shares are held.
    
 
       - Withdrawal through the Merrill Lynch Systematic Withdrawal Plan
         of up to 10% per year of your Class B account value at the time
         the plan is established.
 
   
Your Class B shares convert automatically into Class D shares approximately
eight years after purchase. Any Class B shares received through reinvestment of
dividends or distributions paid on converting shares will also convert at that
time. Class D shares are subject to lower annual expenses than Class B

shares. The conversion of Class B to Class D shares is not a taxable event for
federal income tax purposes.
 
Different conversion schedules apply to Class B shares of different Merrill
Lynch mutual funds. For example, Class B shares of a fixed-income fund convert
approximately ten years after purchase compared to approximately eight years for
equity funds. If you acquire your Class B shares in an exchange from another
fund with a shorter conversion schedule, the Fund's eight year conversion
schedule will apply. If you exchange your Class B shares in the Fund for Class B
shares of a fund with a longer conversion schedule, the other fund's conversion
schedule will apply. The length of time that you hold both the original and
exchanged Class B shares in both funds will count toward the conversion
schedule. The conversion schedule may be modified in certain other cases as
well.
 
   
Class C Shares
    
 
   
If you redeem Class C shares within one year after purchase, you may be charged
a deferred sales charge of 1.00%. The charge will apply to the lesser of the
original cost of the shares being redeemed or the proceeds of your redemption.
You will not be charged a deferred sales charge when you redeem shares that you
acquire through reinvestment of Fund dividends or distributions. The deferred
sales charge relating to Class C shares may be reduced or waived in connection
with participation in certain Merrill Lynch fee-based programs, involuntary
termination of an account in which Fund shares are held and withdrawals through
the Merrill Lynch Systematic Withdrawal Plan.
    
 
Class C shares do not offer a conversion privilege.

[YOUR ACCOUNT ICON] Your Account
 
NET ASSET VALUE -- the market value of the Fund's total assets after deducting
liabilities, divided by the number of shares outstanding.

HOW SHARES ARE PRICED
- --------------------------------------------------------------------------------
 
   
When you buy shares, you pay the NET ASSET VALUE, plus any applicable sales
charge. This is the offering price. Shares are also redeemed at their net asset
value, minus any applicable deferred sales charge. The Fund calculates its net
asset value (generally by using market quotations) each day the New York Stock
Exchange is open, fifteen minutes after the close of business on the Exchange
(the Exchange generally closes at 4:00 p.m. Eastern time). The net asset value
used in determining your price is the next one calculated after your purchase or
redemption order is placed. Foreign securities owned by the Fund may trade on
weekends or other days when the Fund does not price its shares. As a result, the
Fund's net asset value may change on days when you will not be able to purchase
or redeem the Fund's shares.
    
 
Generally, Class A shares will have the highest net asset value because that
class has the lowest expenses, and Class D shares will have a higher net asset
value than Class B or Class C shares. Also dividends paid on Class A and Class D
shares will generally be higher than dividends paid on Class B and Class C
shares because Class A and Class D shares have lower expenses.
 
PARTICIPATION IN MERRILL LYNCH FEE-BASED PROGRAMS
- --------------------------------------------------------------------------------
 
If you participate in certain fee-based programs offered by Merrill Lynch, you
may be able to buy Class A shares at net asset value, including by exchanges
from other share classes. Sales charges on the shares being exchanged may be
reduced or waived under certain circumstances.
 
You generally cannot transfer shares held through a fee-based program into
another account. Instead, you will have to redeem your shares held through the
program and purchase shares of another class, which may be subject to
distribution and account maintenance fees. This may be a taxable event and you
will pay any applicable sales charges.
 
If you leave one of these programs, your shares may be redeemed or automatically
exchanged into another class of Fund shares or into a money market fund. The
class you receive may be the class you originally owned when you entered the
program, or in certain cases, a different class. If the exchange is into Class B
shares, the period before conversion to Class D shares may be modified. Any
redemption or exchange will be at net asset value. However, if you participate
in the program for less than a specified period, you may be charged a fee in
accordance with the terms of the program.

DIVIDENDS -- income paid to shareholders. Dividends may be reinvested in
additional Fund shares as they are paid.

DISTRIBUTIONS -- capital gains paid to shareholders. Distributions may be
reinvested in additional Fund shares as they are paid.

"BUYING A DIVIDEND"

   
Unless your investment is in a tax deferred account, you may want to avoid
buying shares shortly before the Fund pays a dividend or distribution. The
reason? If you buy shares when a fund has realized but not yet distributed
taxable income or capital gains, you will pay the full price for the shares and
then receive a portion of the price back in the form of a taxable distribution.
Before investing you may want to consult your tax adviser. 
    
 
Details about these features and the relevant charges are included in the client
agreement for each fee-based program and are available from your Merrill Lynch
Financial Consultant.
 
DIVIDENDS, CAPITAL GAINS AND TAXES
- --------------------------------------------------------------------------------
 
The Fund will distribute at least annually any net investment income and any net
realized long or short-term capital gains. The Fund may also pay a special
distribution at the end of the calendar year to comply with Federal tax
requirements. If your account is with Merrill Lynch and you would like to
receive DIVIDENDS and DISTRIBUTIONS in cash, contact your Merrill Lynch
Financial Consultant. If your account is with the Transfer Agent and you would
like to receive dividends and distributions in cash, contact the Transfer Agent.

TAXES

You will pay tax on dividends and distributions from the Fund whether you
receive them in cash or additional shares. If you redeem Fund shares or exchange
them for shares of another fund, any gain on the transaction may be subject to
tax. The Fund intends to make distributions that will either be taxed as
ordinary income or capital gains. Capital gains are taxed at different rates
than ordinary income.

If you are neither a lawful permanent resident nor a citizen of the U.S. or if
you are a foreign entity, the Fund's ordinary income dividends (which include
distributions of net short-term capital gains) will generally be subject to a
30% U.S. withholding tax, unless a lower treaty rate applies.

Dividends and interest received by the Fund may give rise to withholding and
other taxes imposed by foreign countries. Tax conventions between certain
countries and the United States may reduce or eliminate such taxes. You may be
able to claim a credit or take a deduction for foreign taxes paid by the Fund if
certain requirements are met.

By law, the Fund must withhold 31% of your distributions and proceeds if you
have not provided a taxpayer identification number or social security number.

This section summarizes some of the consequences under current Federal tax law
of an investment in the Fund. It is not a substitute for personal tax advice.
Consult your personal tax adviser about the potential tax consequences of an
investment in the Fund under all applicable tax laws.

Management of the Fund [MANAGEMENT OF THE FUND ICON]
 
MERRILL LYNCH ASSET MANAGEMENT
- --------------------------------------------------------------------------------
 
Merrill Lynch Asset Management, the Fund's Manager, manages the Fund's
investments and its business operations under the overall supervision of the
Fund's Board of Directors. The Manager has the responsibility for making all
investment decisions for the Fund. The Manager has a sub-advisory agreement with
Merrill Lynch Asset Management U.K. Limited, an affiliate, under which the
Manager may pay a fee for services it receives. The Fund pays the Manager a fee
at the annual rate of 0.60% of the average daily net assets of the Fund.
 
   
Merrill Lynch Asset Management is a part of the Merrill Lynch Asset Management
Group. The Asset Management Group had approximately $499 billion in investment
company and other portfolio assets under management as of November 1998. This
amount includes assets managed for Merrill Lynch affiliates.
    
 
A NOTE ABOUT YEAR 2000
 
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 Fund's management or other Fund
service providers do not properly address this problem before January 1, 2000.
The Fund's management 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 Fund management that they also
expect to resolve the Year 2000 Problem, and the Fund management 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.

                       INVESTMENT OBJECTIVE AND POLICIES
 
     The investment objective of the Fund is to seek high total return from a
combination of capital appreciation and investment income. The Fund will seek to
achieve its objective by investing primarily in a portfolio of convertible debt
securities, convertible preferred stocks and synthetic convertible securities.
Under normal circumstances, the Fund will invest at least 65% of its total
assets in convertible securities and synthetic convertible securities. The
securities in which the Fund invests may be issued by both United States and
non-United States issuers. The investment objective described in this paragraph
is a fundamental policy of the Fund and may not be changed without the approval
of the holders of a majority of the Fund's outstanding voting securities. There
can be no assurance that the investment objective of the Fund will be realized.
 
     The convertible securities to be held by the Fund include any corporate
debt security or preferred stock that may be converted into underlying shares of
common stock. The common stock underlying convertible securities may be issued
by a different entity than the issuer of the convertible securities. Convertible
securities entitle the holder to receive interest payments on corporate debt
securities or the dividend preference on a preferred stock until such time as
the convertible security matures or is redeemed or until the holder elects to
exercise the conversion privilege. Synthetic convertible securities, as such
term is used herein, may be either (i) a debt security or preferred stock that
may be convertible only under certain contingent circumstances or that may pay
the holder a cash amount based on the value of shares of underlying common stock
partly or wholly in lieu of a conversion right (a "Cash-Settled Convertible") or
(ii) a combination of separate securities chosen by the Manager in order to
create the economic characteristics of a convertible security, i.e., a
fixed-income security paired with a security with equity conversion features,
such as an option or warrant (a "Manufactured Convertible"). See "Convertible
Securities" below for additional information concerning convertible securities
and synthetic convertible securities eligible for purchase by the Fund.
 
     The Fund believes that the characteristics of convertible securities make
them appropriate investments for an investment company seeking a high total
return from capital appreciation and investment income. These characteristics
include the potential for capital appreciation as the value of the underlying
common stock increases, the relatively high yield received from dividend or
interest payments as compared to common stock dividends and decreased risks of
decline in value relative to the underlying common stock due to their
fixed-income nature. As a result of the conversion feature, however, the
interest rate or dividend preference on a convertible security is generally less
than would be the case if the securities were issued in nonconvertible form.
 
   
     Under normal circumstances, the Fund may invest up to 35% of its assets in
other types of securities, including common stock, preferred stock, options,
warrants, Long-term Equity Appreciation Participation Securities ("LEAPS") and
nonconvertible debt securities of United States and non-United States issuers.
    
 
     The Fund has established no rating criteria for the debt securities in
which it may invest and such securities may not be rated at all for
creditworthiness. Securities rated in the medium to lower rating categories of
nationally recognized statistical rating organizations and unrated securities of
comparable quality are predominantly speculative with respect to the capacity to
pay interest and repay principal in accordance with the terms of the security
and generally involve a greater volatility of price than securities in higher
rating categories. See Appendix II -- "Ratings of Debt Securities and Preferred
Stock" for additional information regarding ratings of debt securities. In
purchasing such securities, the Fund will rely on the Manager's judgment,
analysis and experience in evaluating the creditworthiness of an issuer of such
securities. The Manager will take into consideration, among other things, the
issuer's financial resources, its sensitivity to economic conditions and trends,
its operating history, the quality of the issuer's management and regulatory
matters. The Fund does not intend to purchase debt securities that are in
default or that the Manager believes will be in default.
 
     The Fund reserves the right as a temporary defensive measure to hold money
market securities of United States and non-United States issuers, or cash
(foreign currencies or United States dollars), in such proportions as, in the
opinion of the Manager, prevailing market, economic or political conditions
warrant. The Fund has established no rating criteria for money market securities
that it may hold as a defensive measure. For this purpose, investments made for
defensive purposes will be maintained only during periods in which the
 
                                        2
<PAGE>   37
 
Manager determines that economic or financial conditions are adverse for holding
or being fully invested in convertible and synthetic convertible securities of
United States and non-United States issuers. A portion of the portfolio normally
will be held in U.S. dollars or dollar-denominated money market securities to
provide for possible redemptions.
 
     In evaluating proposed investments, the Manager will seek to maximize the
total return on the Fund's portfolio in terms of United States dollars. In
analyzing convertible securities, the Manager will consider both the yield on
the convertible security and the potential capital appreciation that is offered
by the underlying common stock. There can be no assurance that the Fund will
achieve its investment objective.
 
   
CONVERTIBLE SECURITIES
    
 
     Convertible securities entitle the holder to receive interest payments paid
on corporate debt securities or the dividend preference on a preferred stock
until such time as the convertible security matures or is redeemed or until the
holder elects to exercise the conversion privilege. Synthetic convertible
securities may be either (i) a debt security or preferred stock that may be
convertible only under certain contingent circumstances or that may pay the
holder a cash amount based on the value of shares of underlying common stock
partly or wholly in lieu of a conversion right (a "Cash-Settled Convertible") or
(ii) a combination of separate securities chosen by the Manager in order to
create the economic characteristics of a convertible security, i.e., a fixed
income security paired with a security with equity conversion features, such as
an option or warrant (a "Manufactured Convertible") or (iii) a synthetic
security manufactured by another party.
 
   
     In analyzing convertible securities, the Manager will consider both the
yield on the convertible security relative to its credit quality and the
potential capital appreciation that is offered by the underlying common stock,
among other things.
    
 
   
     Convertible securities are issued and traded in a number of securities
markets. Even in cases where a substantial portion of the convertible securities
held by the Fund are denominated in United States dollars, the underlying equity
securities may be quoted in the currency of the country where the issuer is
domiciled. With respect to convertible securities denominated in a currency
different from that of the underlying equity securities, the conversion price
may be based on a fixed exchange rate established at the time the security is
issued. As a result, fluctuations in the exchange rate between the currency in
which the debt security is denominated and the currency in which the share price
is quoted will affect the value of the convertible security. As described below,
the Fund is authorized to enter into foreign currency hedging transactions in
which it may seek to reduce the effect of such fluctuations.
    
 
     Apart from currency considerations, the value of convertible securities is
influenced by both the yield of nonconvertible securities of comparable issuers
and by the value of the underlying common stock. The value of a convertible
security viewed without regard to its conversion feature (i.e., strictly on the
basis of its yield) is sometimes referred to as its "investment value." To the
extent interest rates change, the investment value of the convertible security
typically will fluctuate. However, at the same time, the value of the
convertible security will be influenced by its "conversion value," which is the
market value of the underlying common stock that would be obtained if the
convertible security were converted. Conversion value fluctuates directly with
the price of the underlying common stock. If, because of a low price of the
common stock the conversion value is substantially below the investment value of
the convertible security, the price of the convertible security is governed
principally by its investment value.
 
     To the extent the conversion value of a convertible security increases to a
point that approximates or exceeds its investment value, the price of the
convertible security will be influenced principally by its conversion value. A
convertible security will sell at a premium over the conversion value to the
extent investors place value on the right to acquire the underlying common stock
while holding a fixed-income security. The yield and conversion premium of
convertible securities issued in Japan and the Euromarket are frequently
determined at levels that cause the conversion value to affect their market
value more than the securities' investment value.
 
                                        3
<PAGE>   38
 
     Holders of convertible securities generally have a claim on the assets of
the issuer prior to the common stockholders but may be subordinated to other
debt securities of the same issuer. A convertible security may be subject to
redemption at the option of the issuer at a price established in the charter
provision, indenture or other governing instrument pursuant to which the
convertible security was issued. If a convertible security held by the Fund is
called for redemption, the Fund will be required to redeem the security, convert
it into the underlying common stock or sell it to a third party. Certain
convertible debt securities may provide a put option to the holder which
entitles the holder to cause the security to be redeemed by the issuer at a
premium over the stated principal amount of the debt security under certain
circumstances.
 
     As indicated above, synthetic convertible securities may include either
Cash-Settled Convertibles or Manufactured Convertibles. Cash-Settled
Convertibles are instruments that are created by the issuer and have the
economic characteristics of traditional convertible securities but may not
actually permit conversion into the underlying equity securities in all
circumstances. As an example, a private company may issue a Cash-Settled
Convertible that is convertible into common stock only if the company
successfully completes a public offering of its common stock prior to maturity
and otherwise pays a cash amount to reflect any equity appreciation.
Manufactured Convertibles are created by the Manager by combining separate
securities that possess one of the two principal characteristics of a
convertible security, i.e., fixed-income ("fixed-income component") or a right
to acquire equity securities ("convertibility component"). The fixed-income
component is achieved by investing in nonconvertible fixed-income securities,
such as nonconvertible bonds, preferred stocks and money market instruments. The
convertibility component is achieved by investing in call options, warrants,
LEAPS, or other securities with equity conversion features ("equity features")
granting the holder the right to purchase a specified quantity of the underlying
stocks within a specified period of time at a specified price or, in the case of
a stock index option, the right to receive a cash payment based on the value of
the underlying stock index.
 
     A Manufactured Convertible differs from traditional convertible securities
in several respects. Unlike a traditional convertible security, which is a
single security having a unitary market value, a Manufactured Convertible is
comprised of two or more separate securities, each with its own market value.
Therefore, the total "market value" of such a Manufactured Convertible is the
sum of the values of its fixed-income component and its convertibility
component.
 
     More flexibility is possible in the creation of a Manufactured Convertible
than in the purchase of a traditional convertible security. Because many
corporations have not issued convertible securities, the Manager may combine a
fixed-income instrument and an equity feature with respect to the stock of the
issuer of the fixed-income instrument to create a synthetic convertible security
otherwise unavailable in the market. The Manager may also combine a fixed-income
instrument of an issuer with an equity feature with respect to the stock of a
different issuer when the Manager believes such a Manufactured Convertible would
better promote the Fund's objective than alternative investments. For example,
the Manager may combine an equity feature with respect to an issuer's stock with
a fixed-income security of a different issuer in the same industry to diversify
the Fund's credit exposure, or with a U.S. Treasury instrument to create a
Manufactured Convertible with a higher credit profile than a traditional
convertible security issued by that issuer. A Manufactured Convertible also is a
more flexible investment in that its two components may be purchased separately
and, upon purchasing the separate securities, "combined" to create a
Manufactured Convertible. For example, the Fund may purchase a warrant for
eventual inclusion in a Manufactured Convertible while postponing the purchase
of a suitable bond to pair with the warrant pending development of more
favorable market conditions.
 
     The value of a Manufactured Convertible may respond differently to certain
market fluctuations than would a traditional convertible security with similar
characteristics. For example, in the event the Fund created a Manufactured
Convertible by combining a short-term U.S. Treasury instrument and a call option
on a stock, the Manufactured Convertible would likely outperform a traditional
convertible of similar maturity and which is convertible into that stock during
periods when Treasury instruments outperform corporate fixed-income securities
and underperform during periods when corporate fixed-income securities
outperform Treasury instruments.

DESCRIPTION OF CERTAIN INVESTMENTS
 
     Depositary Receipts.  The Fund may invest in the securities of foreign
issuers in the form of sponsored or unsponsored American Depositary Receipts
("ADRs"), European Depositary Receipts ("EDRs") and Global Depositary Receipts
("GDRs") (collectively, "Depositary Receipts") or other securities convertible
into securities of foreign issuers. Depositary Receipts may not necessarily be
denominated in the same currency as the underlying securities into which they
may be converted. ADRs are receipts typically issued by an American bank or
trust company that evidence ownership of underlying securities issued by a
foreign corporation. EDRs are receipts issued in Europe that evidence a similar
ownership arrangement. GDRs are receipts issued throughout the world that
evidence a similar arrangement. Generally, ADRs, in registered form, are
designed for use in the U.S. securities markets, and EDRs, in bearer form, are
designed for use in European securities markets. GDRs are tradeable both in the
U.S. and in Europe and are designed for use throughout the world. The Fund may
invest in unsponsored Depositary Receipts. The issuers of unsponsored Depositary
Receipts are not obligated to disclose material information in the United
States, and, therefore, there may be less information available regarding such
issuers and there may not be a correlation between such information and the
market value of the Depositary Receipts.
 
     Warrants.  The Fund may invest in warrants, which are securities
permitting, but not obligating, their holder to subscribe for other securities.
Warrants do not carry with them the right to dividends or voting rights with
respect to the securities that they entitle their holders to purchase, and they
do not represent any rights in the assets of the issuer. As a result, an
investment in warrants may be considered more speculative than certain other
types of investments. In addition, the value of a warrant does not necessarily
change with the value of the underlying securities and a warrant ceases to have
value if it is not exercised prior to its expiration date.
 
     Illiquid Securities.  The Fund may invest up to 15% of its net assets in
securities that lack an established secondary trading market or otherwise are
considered illiquid. The Fund may invest in securities of issuers that are sold
in private placement transactions between the issuers and their purchasers and
that are neither listed on an exchange nor traded in other established markets.
In many cases, privately placed securities will be subject to contractual or
legal restrictions on transfer. As a result of the absence of a public trading
market, privately placed securities in turn may be less liquid or illiquid and
more difficult to value than publicly traded securities. To the extent that
privately placed securities may be resold in privately negotiated transactions,
the prices realized from the sales, due to illiquidity, could be less than those
originally paid by the Fund or less than their fair market value. In addition,
issuers whose securities are not publicly traded may not be subject to the
disclosure and other investor protection requirements that may be applicable if
their securities were publicly traded. If any privately placed securities held
by the Fund are required to be registered under the securities laws of one or
more jurisdictions before being resold, the Fund may be required to bear the
expenses of registration. Certain of the Fund's investments in private
placements may consist of direct investments and may include investments in
smaller, less-seasoned issuers, which may involve greater risks. These issuers
may have limited product lines, markets or financial resources, or they may be
dependent on a limited management group. In making investments in such
securities, the Fund may obtain access to material nonpublic information which
may restrict the Fund's ability to conduct portfolio transactions in such
securities.
 
     The Fund may purchase securities that are not registered ("restricted
securities") under the Securities Act of 1933, as amended (the "Securities
Act"), but can be offered and sold to "qualified institutional buyers" under
Rule 144A under the Securities Act. The Board of Directors has determined to
treat as liquid Rule 144A securities that are either (i) freely tradeable in
their primary markets offshore or (ii) non-investment grade debt securities
which the Manager determines are as liquid as publicly-registered non-
investment grade debt securities. The Board of Directors has adopted guidelines
and delegated to the Manager the daily function of determining and monitoring
liquidity of restricted securities. The Board of Directors, however, will retain
sufficient oversight and be ultimately responsible for the determinations. Since
it is not possible to predict with assurance exactly how this market for
restricted securities sold and offered under Rule 144A will develop, the Board
of Directors will carefully monitor the Fund's investments in these securities.
This investment practice could have the effect of increasing the level of
illiquidity in the Fund to the extent that qualified institutional buyers become
for a time uninterested in purchasing these securities.
 
                                        5

     Certain indexed and inverse securities may have the effect of providing
investment leverage because the rate of interest or amount of principal payable
increases or decreases at a rate that is a multiple of the changes in the
relevant index. As a consequence, the market value of such securities may be
substantially more volatile than the market values of other debt securities. The
Fund believes that indexed and inverse securities may provide portfolio
management flexibility that permits the Fund to seek enhanced returns, hedge
other portfolio positions or vary the degree of portfolio leverage with greater
efficiency than would otherwise be possible under certain market conditions.
    
 
OTHER INVESTMENT POLICIES AND PRACTICES
 
     Portfolio Strategies Involving Options, Futures and Foreign Exchange
Transactions.  The Fund is authorized to engage in certain investment practices
involving the use of options, futures and foreign exchange, which may expose the
Fund to certain risks. These investment practices and the associated risks are
described in detail in Appendix I attached to this Statement of Additional
Information.
 
     Portfolio Transactions.  Subject to policies established by the Board of
Directors of the Fund, the Manager is primarily responsible for the execution of
the Fund's portfolio transactions. Since portfolio transactions may be effected
on foreign securities exchanges, the Fund may incur settlement delays on certain
of such exchanges. See "Risk Factors and Special Considerations." In executing
portfolio transactions, the Manager seeks to obtain the best net results for the
Fund, taking into account such factors as price (including the applicable
brokerage commissions or dealer spread), size of order, difficulty of execution,
operational facilities of the firm involved and the firm's risk in positioning a
block of securities. While the Manager generally seeks reasonably competitive
fees, commissions or spreads, the Fund does not necessarily pay the lowest fee,
commission or spread available. The Fund may invest in certain securities traded
in the over-the-counter ("OTC") market and, where possible, will deal directly
with the dealers who make a market in the securities involved except in those
circumstances where better prices and execution are available elsewhere. Such
dealers usually are acting as principal for their own account. On occasion,
securities may be purchased directly from the issuer. Such portfolio securities
are generally traded on a net basis and do not normally involve either brokerage
commissions or transfer taxes. The Fund contemplates that, consistent with its
policy of obtaining the best net results, it will place orders for transactions
with a number of brokers and dealers, including Merrill Lynch, an affiliate of
the Manager. Subject to obtaining the best price and execution, securities firms
that provide supplemental investment research to the Manager, including Merrill
Lynch, may receive orders for transactions by the Fund. Information so received
will be in addition to, and not in lieu of, the services required to be
performed by the Manager and the expenses of the Manager will not necessarily be
reduced as a result of the receipt of such supplemental information. See
"Management of the Fund -- Management and Advisory Arrangements."
 
     Under the Investment Company Act of 1940, as amended (the "Investment
Company Act"), persons affiliated with the Fund and persons who are affiliated
with such affiliated persons, including Merrill Lynch, Pierce, Fenner & Smith
Incorporated ("Merrill Lynch"), are prohibited from dealing with the Fund as a
principal in the purchase and sale of securities unless a permissive order
allowing such transactions is obtained from the Commission. Affiliated persons
of the Fund, and affiliated persons of such affiliated persons, may serve as the
Fund's broker in transactions conducted on an exchange and in OTC transactions
conducted on an agency basis and may receive brokerage commissions from the
Fund. In addition, the Fund may not purchase securities during the existence of
any underwriting syndicate for such securities of which Merrill Lynch is a
member except pursuant to procedures approved by the Board of Directors of the
Fund that either comply with rules adopted by the Commission or with
interpretations of the Commission staff. To the extent Merrill Lynch is active
in distributions of securities of issuers in certain foreign countries, the Fund
may be disadvantaged in that it may not purchase securities in such
distributions or may be limited in the amount it may purchase. In addition,
consistent with the Conduct Rules of the NASD, the Manager may consider sales of
shares of the Fund as a factor in the selection of brokers or dealers to execute
portfolio transactions for the Fund. It is expected that the majority of the
shares of the Fund will be sold by Merrill Lynch. Costs associated with
transactions in foreign securities are generally higher than in the U.S.,
although the Fund will endeavor to achieve the best net results in effecting its
portfolio transactions.
 
                                        6
<PAGE>   41
 
     The Fund anticipates that its brokerage transactions involving securities
of companies domiciled in countries other than the United States will be
conducted primarily on the principal stock exchanges of such countries.
Brokerage commissions and other transaction costs on foreign securities
exchanges are generally higher than in the United States, although the Fund will
endeavor to achieve the best net results in effecting such transactions. There
generally is less governmental supervision and regulation of foreign stock
exchanges and brokers than in the United States.
 
     The Fund's ability and decisions to purchase and sell portfolio securities
may be affected by foreign laws and regulations relating to the convertibility
and repatriation of assets.
 
     Repurchase Agreements.  The Fund may invest in securities pursuant to
repurchase agreements. Under a repurchase agreement, the seller agrees, upon
entering into the contract with the Fund, to repurchase a security (typically a
security issued or guaranteed by the U.S. Government) at a mutually agreed-upon
time and price, thereby determining the yield during the term of the agreement.
This results in a fixed yield for the Fund insulated from fluctuations in the
market value of the underlying security during such period although, to the
extent the repurchase agreement is not denominated in U.S. dollars, the Fund's
return may be affected by currency fluctuations. Repurchase agreements may be
entered into only with financial institutions that (i) have, in the opinion of
the Manager, substantial capital relative to the Fund's exposure, or (ii) have
provided the Fund with a third-party guaranty or other credit enhancement. The
Fund takes possession of the underlying securities when investing in repurchase
agreements. Nevertheless, if the seller were to default on its obligation to
repurchase a security under a repurchase agreement and the market value of the
underlying security at such time was less than the Fund had paid to the seller,
the Fund would realize a loss. The Fund may not invest more than 15% of its net
assets in repurchase agreements maturing in more than seven days, together with
all other illiquid securities.
 
   
     When Issued Securities and Forward Commitment Transactions.  The Fund may
purchase or sell securities that it is entitled to receive on a when issued
basis, and it may purchase or sell securities for delayed delivery. These
transactions occur when securities are purchased or sold by the Fund with
payment and delivery taking place in the future to secure what is considered an
advantageous yield and price to the Fund at the time of entering into the
transaction. Although the Fund has not established any limit on the percentage
of its assets that may be committed in connection with such transactions, the
Fund will maintain a segregated account with its custodian of cash, cash
equivalents, U.S. Government securities or other liquid securities denominated
in U.S. dollars or non-U.S. currencies in an aggregate amount equal to the
amount of its commitments in connection with such purchase transactions.
    
 
   
     There can be no assurance that a security purchased on a when issued basis
or purchased or sold for delayed delivery will be issued, and the value of the
security, if issued, on the delivery date may be more or less than its purchase
price. The Fund may bear the risk of a decline in the value of such security and
may not benefit from an appreciation in the value of the security during the
commitment period.
    
 
     Standby Commitment Agreements.  The Fund, from time to time, may enter into
standby commitment agreements. Such agreements commit the Fund, for a stated
period of time, to purchase a stated amount of equity securities that may be
issued and sold to the Fund at the option of the issuer. The price of the
security is fixed at the time of the commitment. At the time of entering into
the agreement, the Fund is paid a commitment fee, regardless of whether or not
the security is ultimately issued. The Fund will enter into such agreements only
for the purpose of investing in the security underlying the commitment at a
price that is considered advantageous to the Fund. The Fund will not enter into
a standby commitment with a remaining term in excess of 45 days and presently
will limit its investment in such commitments so that the aggregate purchase
price of the securities subject to such commitments, together with the value of
portfolio securities subject to legal restrictions on resale that affect their
marketability, will not exceed 15% of its net assets taken at the time of
acquisition of such a commitment. The Fund at all times will maintain a
segregated account with its custodian of cash, cash equivalents, U.S. Government
securities or other liquid securities denominated in U.S. dollars or non-U.S.
currencies in an aggregate amount equal to the purchase price of the securities
underlying a commitment.
 
                                        7
<PAGE>   42
 
     There can be no assurance that the securities subject to a standby
commitment will be issued, and the value of the security, if issued, on the
delivery date may be more or less than its purchase price. Since the issuance of
the security underlying the commitment is at the option of the issuer, the Fund
may bear the risk of a decline in the value of such security and may not benefit
from an appreciation in the value of the security during the commitment period.
 
     The purchase of a security subject to a standby commitment agreement and
the related commitment fee will be recorded on the date on which the security
can reasonably be expected to be issued, and the value of the security
thereafter will be reflected in the calculation of the Fund's net asset value.
The cost basis of the security will be adjusted by the amount of the commitment
fee. In the event the security is not issued, the commitment fee will be
recorded as income on the expiration date of the standby commitment.
 
     Lending of Portfolio Securities.  The Fund may from time to time lend
securities from its portfolio with a value not exceeding 33 1/3% of its total
assets to banks, brokers and other financial institutions and receive collateral
in cash or securities issued or guaranteed by the United States Government. Such
collateral will be maintained at all times in an amount equal to at least 100%
of the current market value of the loaned securities. During the period of such
a loan, the Fund receives the income on the loaned securities and either
receives the income on the collateral or other compensation, i.e., negotiated
loan premium or fee, for entering into the loan and thereby increases its yield.
In the event that the borrower defaults on its obligation to return borrowed
securities, because of insolvency or otherwise, the Fund could experience delays
and costs in gaining access to the collateral and could suffer a loss to the
extent that the value of the collateral falls below the market value of the
borrowed securities.
 
     Short Sales.  The Fund may make short sales of securities. A short sale is
a transaction in which the Fund sells a security it does not own in anticipation
that the market price of that security may decline. The Fund expects to make
short sales both as a form of hedging to offset potential declines in long
positions in similar securities and in order to maintain portfolio flexibility.
 
     When the Fund makes a short sale, it must borrow the security sold short
and deliver it to the broker-dealer through which it made the short sale as
collateral for its obligation to deliver the security upon conclusion of the
sale. The Fund may have to pay a fee to borrow particular securities and is
often obligated to pay over any payments received on such borrowed securities.
 
     The Fund's obligation to replace the borrowed security will be secured by
collateral deposited with the broker-dealer. With respect to uncovered short
positions, the Fund will also be required to deposit similar collateral with its
custodian to the extent, if any, necessary so that the value of both collateral
deposits in the aggregate is at all times equal to at least 100% of the current
market value of the security sold short. Depending on arrangements made with the
broker-dealer from which it borrowed the security regarding payment over of any
payments received by the Fund on such security, the Fund may not receive any
payments (including interest) on its collateral deposited with such
broker-dealer.
 
     If the price of the security sold short increases between the time of the
short sale and the time the Fund replaces the borrowed security, the Fund will
incur a loss; conversely, if the price declines, the Fund will realize a gain.
Any gain will be decreased, and any loss increased, by the transaction costs
described above. Although the Fund's gain is limited to the price at which it
sold the security short, its potential loss is theoretically unlimited.
 
     The Fund will not make a short sale if, after giving effect to such sale,
the market value of all securities sold short exceeds 25% of the value of its
total assets or the Fund's aggregate short sales of a particular class of
securities exceeds 25% of the outstanding securities of that class. The Fund may
also make short sales "against the box" without respect to such limitations. In
this type of short sale, at the time of the sale, the Fund owns or has the
immediate and unconditional right to acquire at no additional cost the identical
security.
 
INVESTMENT RESTRICTIONS
 
     The Fund has adopted a number of fundamental and non-fundamental investment
restrictions and policies relating to the investment of its assets and its
activities. The fundamental policies set forth below may
                                        8
<PAGE>   43
 
not be changed without the approval of the holders of a majority of the Fund's
outstanding voting securities (which for this purpose and under the Investment
Company Act means the lesser of (i) 67% of the Fund's shares present at a
meeting at which more than 50% of the outstanding shares of the Fund are
represented or (ii) more than 50% of the Fund's outstanding shares). The Fund
may not:
 
          (1) Invest more than 25% of its assets, taken at market value at the
     time of each investment, in the securities of issuers in any particular
     industry (excluding the U.S. Government and its agencies and
     instrumentalities). For the purpose of this restriction, states,
     municipalities and their political subdivisions are not considered part of
     any industry.
 
          (2) Make investments for the purpose of exercising control or
     management. Investments by the Fund in wholly-owned investment entities
     created under the laws of certain countries will not be deemed to be the
     making of investments for the purpose of exercising control or management.
 
          (3) Purchase or sell real estate, except that, to the extent permitted
     by applicable law, the Fund may invest in securities directly or indirectly
     secured by real estate or interests therein or issued by companies that
     invest in real estate or interests therein.
 
          (4) Make loans to other persons, except that the acquisition of bonds,
     debentures or other corporate debt securities and investment in government
     obligations, commercial paper, pass-through instruments, certificates of
     deposit, bankers acceptances, repurchase agreements or any similar
     instruments shall not be deemed to be the making of a loan, and except
     further that the Fund may lend its portfolio securities, provided that the
     lending of portfolio securities may be made only in accordance with
     applicable law and the guidelines set forth in the Fund's Prospectus and
     Statement of Additional Information, as they may be amended from time to
     time.
 
          (5) Issue senior securities to the extent such issuance would violate
     applicable law.
 
          (6) Borrow money, except that (i) the Fund may borrow from banks (as
     defined in the Investment Company Act) in amounts up to 33 1/3% of its
     total assets (including the amount borrowed), (ii) the Fund may, to the
     extent permitted by applicable law, borrow up to an additional 5% of its
     total assets for temporary purposes, (iii) the Fund may obtain such
     short-term credit as may be necessary for the clearance of purchases and
     sales of portfolio securities and (iv) the Fund may purchase securities on
     margin to the extent permitted by applicable law. The Fund may not pledge
     its assets other than to secure such borrowings or, to the extent permitted
     by the Fund's investment policies as set forth in its Prospectus and
     Statement of Additional Information, as they may be amended from time to
     time, in connection with hedging transactions, short sales, when-issued and
     forward commitment transactions and similar investment strategies.
 
          (7) Underwrite securities of other issuers except insofar as the Fund
     technically may be deemed an underwriter under the Securities Act in
     selling portfolio securities.
 
          (8) Purchase or sell commodities or contracts on commodities, except
     to the extent that the Fund may do so in accordance with applicable law and
     the Fund's Prospectus and Statement of Additional Information, as they may
     be amended from time to time, and without registering as a commodity pool
     operator under the Commodity Exchange Act.
 
     In addition, the Fund has adopted non-fundamental investment restrictions
that may be changed by the Board of Directors without a vote of the Fund's
shareholders. Under the non-fundamental investment restrictions, the Fund may
not:
 
          (a) Purchase securities of other investment companies, except to the
     extent permitted by applicable law. As a matter of policy, however, the
     Fund will not purchase shares of any registered open-end investment company
     or registered unit investment trust, in reliance on Section 12(d)(1)(F) or
     (G) (the "fund of funds" provisions) of the Investment Company Act at any
     time the Fund's shares are owned by another investment company that is part
     of the same group of investment companies as the Fund.
 
                                        9
<PAGE>   44
 
          (b) Make short sales of securities or maintain a short position,
     except to the extent permitted by applicable law.
 
          (c) Invest in securities that cannot be readily resold because of
     legal or contractual restrictions or that cannot otherwise be marketed,
     redeemed or put to the issuer or a third party, if at the time of
     acquisition more than 15% of its net assets would be invested in such
     securities. This restriction shall not apply to securities that mature
     within seven days or securities, that the Board of Directors of the Fund
     has otherwise determined to be liquid pursuant to applicable law.
     Securities purchased in accordance with Rule 144A under the Securities Act
     and determined to be liquid by the Board of Directors are not subject to
     the limitations set forth in this investment restriction.
 
          (d) Notwithstanding fundamental investment restriction (6) above,
     borrow money or pledge its assets, except that the Fund (a) may borrow from
     a bank as a temporary measure for extraordinary or emergency purposes or to
     meet redemptions in amounts not exceeding 33 1/3% (taken at market value)
     of its total assets and pledge its assets to secure such borrowings, (b)
     may obtain such short-term credit as may be necessary for the clearance of
     purchases and sales of portfolio securities and (c) may purchase securities
     on margin to the extent permitted by applicable law. However, at the
     present time, applicable law prohibits the Fund from purchasing securities
     on margin. The deposit or payment by the Fund of initial or variation
     margin in connection with financial futures contracts or options
     transactions is not considered to be the purchase of a security on margin.
     The purchase of securities while borrowings are outstanding will have the
     effect of leveraging the Fund. Such leveraging or borrowing increases the
     Fund's exposure to capital risk, and borrowed funds are subject to interest
     costs which will reduce net income. The Fund will not purchase securities
     while borrowings exceed 5% of its total assets.
 
     Portfolio securities of the Fund generally may not be purchased from, sold
or loaned to the Manager or its affiliates or any of their directors, officers
or employees, acting as principal, unless pursuant to a rule or exemptive order
under the Investment Company Act.
 
     As another non-fundamental policy, the Fund will not invest in securities
that are (a) subject to material legal restrictions on repatriation of assets or
(b) cannot be readily resold because of legal or contractual restrictions or
which are not otherwise readily marketable, including repurchase agreements and
purchase and sale contracts maturing in more than seven days, if, regarding all
such securities, more than 15% of its net assets taken at market value would be
invested in such securities.
 
     Non-Diversified Status.  The Fund is classified as non-diversified within
the meaning of the Investment Company Act, which means that the Fund is not
limited by such Act in the proportion of its assets that it may invest in
securities of a single issuer. The Fund's investments will be limited, however,
in order to qualify for the special treatment afforded "regulated investment
companies" under the Internal Revenue Code of 1986, as amended (the "Code"). See
"Distributions and Taxes -- Taxes." To qualify, the Fund will comply with
certain requirements, including limiting 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 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 of a single issuer, and the Fund will not own more than 10% of the
outstanding voting securities of a single issuer. A fund that elects to be
classified as "diversified" under the Investment Company Act must satisfy the
foregoing 5% and 10% requirements 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, and the Fund may be more
susceptible to any single economic, political or regulatory occurrence than a
diversified company.
 
     For the purposes of investment restriction (1) as well as the
diversification requirements set forth above with respect to regulated
investment companies, and to the extent required by the Commission or its staff,
the Fund, as non-fundamental policy, will consider securities issued or
guaranteed by the government of any one foreign country as the obligations of a
single issuer.
 
                                       10
<PAGE>   45
 
     Because of the affiliation of Merrill Lynch with the Manager, the Fund is
prohibited from engaging in certain transactions involving Merrill Lynch or its
affiliates except pursuant to an exemptive order under the Investment Company
Act. See "Portfolio Transactions." Without such an exemptive order the Fund
would be prohibited from engaging in portfolio transactions with Merrill Lynch
or any of its affiliates acting as principal and from purchasing securities in
public offerings that are not registered under the Securities Act in which
Merrill Lynch or any of its affiliates participate as an underwriter or dealer.
 
PORTFOLIO TURNOVER
 
   
     Generally, the Fund does not purchase securities for short-term trading
profits. However, 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 Manager. As a result of its investment policies, the Fund may
engage in a substantial number of portfolio transactions. The portfolio turnover
rate is calculated by dividing the lesser of the Fund's annual sales or
purchases of portfolio securities (exclusive of purchases or sales of all
securities whose maturities at the time of acquisition were one year or less) by
the monthly average value of the securities in the portfolio during the year. A
high portfolio turnover rate involves certain tax consequences and
correspondingly greater transaction costs in the form of dealer spreads and
brokerage commissions, which are borne directly by the Fund.

     Directors of the Fund, members of the Boards of other MLAM-advised
investment companies, ML & Co. and its subsidiaries (the term "subsidiaries,"
when used herein with respect to ML & Co., includes MLAM, FAM and certain other
entities directly or indirectly wholly owned and controlled by ML & Co.) and
their directors and employees, and any trust, pension, profit-sharing or other
benefit plan for such persons, may purchase Class A shares of the Fund at net
asset value.
 
MANAGEMENT AND ADVISORY ARRANGEMENTS
 
     Management Services.  The Manager provides the Fund with investment
advisory and management services. Subject to the supervision of the Board of
Directors, the Manager is responsible for the actual management of the Fund's
portfolio and constantly reviews the Fund's holdings in light of its own
research analysis and that from other relevant sources. The responsibility for
making decisions to buy, sell or hold a particular security rests with the
Manager. The Manager performs certain of the other administrative services and
provides all the office space, facilities, equipment and necessary personnel for
management of the Fund.
 
     Management Fee.  The Fund has entered into an investment advisory agreement
with the Manager (the "Management Agreement"). The Manager also served as the
Fund's Manager prior to the conversion of the Fund from a closed-end investment
company to an open-end investment company on August 4, 1997. The Manager
receives for its services to the Fund monthly compensation at the annual rate of
0.60% of the average daily net assets of the Fund. For the fiscal year ended
December 31, 1996 (during which period the Fund operated as a closed-end
investment company), the fees paid by the Fund to the Manager aggregated
$1,695,738. For the period January 1, 1997 to August 31, 1997, the fees paid by
the Fund to the Manager aggregated $1,102,729. For the fiscal year ended August
31, 1998, the fees paid by the Fund to the Manager aggregated $570,057.
 
     The Manager has also entered into a sub-advisory agreement (the
"Sub-Advisory Agreement") with Merrill Lynch Asset Management U.K. Limited
("MLAM U.K."), an indirect, wholly owned subsidiary of ML & Co. and an affiliate
of the Manager, pursuant to which the Manager pays MLAM U.K. a fee for providing
investment advisory services to the Manager with respect to the Fund in an
amount to be determined from time to time by the Manager and MLAM U.K. but in no
event in excess of the amount the Manager actually receives for providing
services to the Fund pursuant to the Management Agreement. Unless earlier
terminated as described below, the Sub-Advisory Agreement will remain in effect
until July 31, 1999 and thereafter, if approved at least annually (a) by the
Directors 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 Investment Company 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
 
                                       13
<PAGE>   48
 
shareholders of the Fund. MLAM U.K. has offices at Milton Gate, 1 Moor Lane,
London EC2Y 9HA, England.
 
     Payment of Fund Expenses.  The Management Agreement obligates the Manager
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 fees of all Directors of the Fund who are affiliated persons of
ML & Co. or any of its affiliates. The Fund pays all other expenses incurred in
its operation of the Fund, including, among other things, taxes, expenses for
legal and auditing services, costs of printing proxies, stock certificates,
shareholder reports and prospectuses and statements of additional information,
except to the extent paid by Merrill Lynch Funds Distributor, a division of PFD
(the "Distributor") as described below, charges of the custodian, any sub-
custodian and transfer agent, expenses of the redemption of shares, Commission
fees, expenses of registering the shares under Federal, state or foreign laws,
fees and expenses of non-interested Directors, accounting and pricing costs
(including the daily calculation of net asset value), insurance, interest,
brokerage costs, litigation and other extraordinary or nonrecurring expenses,
and other expenses properly payable by the Fund. Accounting services are
provided to the Fund by the Manager, and the Fund reimburses the Manager for its
costs in connection with such services. As required by the Fund's distribution
agreements, the Distributor will pay the promotional expenses of the Fund
incurred in connection with the offering of shares of the Fund. Certain expenses
in connection with the account maintenance and distribution of Class B and Class
C shares will be financed by the Fund pursuant to the Distribution Plans in
compliance with Rule 12b-1 under the Investment Company Act. See "Purchase of
Shares -- Distribution Plans."
 
     Organization of the Manager.  The Manager is a limited partnership, the
partners of which are ML & Co., a financial services holding company and the
parent of Merrill Lynch, and Princeton Services. ML & Co. and Princeton Services
are "controlling persons" of the Manager as defined under the Investment Company
Act because of their ownership of its voting securities or their power to
exercise a controlling influence over its management or policies. Similarly, the
following entities may be considered "controlling persons" of MLAM U.K.: Merrill
Lynch Europe PLC (MLAM U.K.'s parent), a subsidiary of Merrill Lynch
International Holdings, Inc., a subsidiary of Merrill Lynch International, Inc.,
a subsidiary of ML & Co.
 
     Duration and Termination.  Unless earlier terminated as described below,
the Management Agreement will remain in effect until July 31, 1999 and
thereafter, if approved at least annually (a) by the Board of Directors 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 Investment Company Act) of any such party. Such contracts are not
assignable and may be terminated without penalty on 60 days' written notice at
the option of either party or by vote of the shareholders of the Fund.
 
     Transfer Agency Services.  Financial Data Services, Inc. (the "Transfer
Agent"), a subsidiary of ML & Co., acts as the Fund's Transfer Agent pursuant to
a Transfer Agency, Dividend Disbursing Agency and Shareholder Servicing Agency
Agreement (the "Transfer Agency Agreement"). Pursuant to the Transfer Agency
Agreement, the Transfer Agent is responsible for the issuance, transfer and
redemption of shares and the opening and maintenance of shareholder accounts.
Pursuant to the Transfer Agency Agreement, the Transfer Agent receives a fee of
$11.00 per Class A or Class D account and $14.00 per Class B or Class C account
and is entitled to reimbursement for certain transaction charges and
out-of-pocket expenses incurred by the Transfer Agent under the Transfer Agency
Agreement. Additionally, a $.20 monthly closed account charge will be assessed
on all accounts which close during the calendar year. Application of this fee
will commence the month following the month the account is closed. At the end of
the calendar year, no further fees will be due. For purposes of the Transfer
Agency Agreement, the term "account" includes a shareholder account maintained
directly by the Transfer Agent and any other account representing the beneficial
interest of a person in the relevant share class on a recordkeeping system,
provided the recordkeeping system is maintained by a subsidiary of ML & Co.
 
     Distribution Expenses.  The Fund has entered into four separate
distribution agreements with the Distributor in connection with the continuous
offering of each class of shares of the Fund (the "Distribution Agreements").
The Distribution Agreements obligate the Distributor to pay certain expenses in
connection
 
                                       14
<PAGE>   49
 
with the offering of each class of shares of the Fund. After the prospectuses,
statements of additional information and periodic reports have been prepared,
set in type and mailed to shareholders, the Distributor pays for the printing
and distribution of copies thereof used in connection with the offering to
dealers and investors. The Distributor also pays for other supplementary sales
literature and advertising costs. The Distribution Agreements are subject to the
same renewal requirements and termination provisions as the Management Agreement
described above.
 
CODE OF ETHICS
 
     The Board of Directors of the Fund has adopted a Code of Ethics under Rule
17j-1 of the Investment Company Act which incorporates the Code of Ethics of the
Manager (together, the "Codes"). The Codes significantly restrict the personal
investing activities of all employees of the Manager and, as described below,
impose additional, more onerous, restrictions on fund investment personnel.
 
     The Codes require that all employees of the Manager pre-clear any personal
securities investment (with limited exceptions, such as government securities).
The pre-clearance 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 Manager include
a ban on acquiring any securities in a "hot" initial public offering and a
prohibition from profiting on short-term trading in 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 Manager.
Furthermore, the Codes provide for trading "blackout periods" which 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).
 
                               PURCHASE OF SHARES
 
     Reference is made to "How to Buy, Sell, Transfer and Exchange Shares" in
the Prospectus.
 
     The Fund offers four classes of shares under the Merrill Lynch Select
Pricing(SM) System: shares of Class A and Class D are sold to investors choosing
the initial sales charge alternatives and shares of Class B and Class C are sold
to investors choosing the deferred sales charge alternatives. Each Class A,
Class B, Class C or Class D share of the Fund represents an identical interest
in the investment portfolio of the Fund and has the same rights, except that
Class B, Class C and Class D shares bear the expenses of the ongoing account
maintenance fees (also known as service fees) and Class B and Class C shares
bear the expenses of the ongoing distribution fees and the additional
incremental transfer agency costs resulting from the deferred sales charge
arrangements. The contingent deferred sales charges ("CDSCs"), distribution fees
and account maintenance fees that are imposed on Class B and Class C shares, as
well as the account maintenance fees that are imposed on Class D shares, are
imposed directly against those classes and not against all assets of the Fund
and, accordingly, such charges do not affect the net asset value of any other
class or have any impact on investors choosing another sales charge option.
Dividends paid by the Fund for each class of shares are calculated in the same
manner at the same time and differ only to the extent that account maintenance
and distribution fees and any incremental transfer agency costs relating to a
particular class are borne exclusively by that class. Each class has different
exchange privileges. See "Shareholder Services -- Exchange Privilege."
 
     Investors should understand that the purpose and function of the initial
sales charges with respect to the Class A and Class D shares are the same as
those of the CDSCs and distribution fees with respect to the Class B and Class C
shares in that the sales charges and distribution fees applicable to each class
provide for the financing of the distribution of the shares of the Fund. The
distribution-related revenues paid with respect to a class will not be used to
finance the distribution expenditures of another class. Sales personnel may
receive different compensation for selling different classes of shares.
 
     The Merrill Lynch Select Pricing(SM) System is used by more than 50
registered investment companies advised by MLAM or FAM. Funds advised by MLAM or
FAM that utilize the Merrill Lynch Select Pricing(SM) System are referred to
herein as "Select Pricing Funds."
 
                                       15
<PAGE>   50
 
     The Fund or the Distributor may suspend the continuous offering of the
Fund's shares of any class at any time in response to conditions in the
securities markets or otherwise and may thereafter resume such offering from
time to time. Neither the Distributor nor the dealers are permitted to withhold
placing orders to benefit themselves by a price change. Merrill Lynch may charge
its customers a processing fee (presently $5.35) to confirm a sale of shares to
such customers. Purchases made directly through the Transfer Agent are not
subject to the processing fee.
 
INITIAL SALES CHARGE ALTERNATIVES -- CLASS A AND CLASS D SHARES
 
     Investors who prefer an initial sales charge alternative may elect to
purchase Class D shares or, if an eligible investor, Class A shares. Investors
choosing the initial sales charge alternative who are eligible to purchase Class
A shares should purchase Class A shares rather than Class D shares because there
is an account maintenance fee imposed on Class D shares. Investors qualifying
for significantly reduced initial sales charges may find the initial sales
charge alternative particularly attractive because similar sales charge
reductions are not available with respect to the deferred sales charges imposed
in connection with purchases of Class B or Class C shares. Investors not
qualifying for reduced initial sales charges who expect to maintain their
investment for an extended period of time also may elect to purchase Class A or
Class D shares, because over time the accumulated ongoing account maintenance
and distribution fees on Class B or Class C shares may exceed the initial sales
charges and, in the case of Class D shares, the account maintenance fee.
Although some investors who previously purchased Class A shares may no longer be
eligible to purchase Class A shares of other Select Pricing Funds, those
previously purchased Class A shares, together with Class B, Class C and Class D
share holdings, will count toward a right of accumulation which may qualify the
investor for a reduced initial sales charge on new initial sales charge
purchases. In addition, the ongoing Class B and Class C account maintenance and
distribution fees will cause Class B and Class C shares to have higher expense
ratios, pay lower dividends and have lower total returns than the initial sales
charge shares. The ongoing Class D account maintenance fees will cause Class D
shares to have a higher expense ratio, pay lower dividends and have a lower
total return than Class A shares.
 
     The term "purchase," as used in the Prospectus and this Statement of
Additional Information in connection with an investment in Class A and Class D
shares of the Fund, refers to a single purchase by an individual or to
concurrent purchases, which in the aggregate are at least equal to the
prescribed amounts, by an individual, his or her spouse and their children under
the age of 21 years purchasing shares for his, her or their own account and to
single purchases by a trustee or other fiduciary purchasing shares for a single
trust estate or single fiduciary account although more than one beneficiary is
involved. The term "purchase" also includes purchases by any "company," as that
term is defined in the Investment Company Act, but does not include purchases by
any such company that has not been in existence for at least six months or which
has no purpose other than the purchase of shares of the Fund or shares of other
registered investment companies at a discount; provided, however, that it shall
not include purchases by any group of individuals whose sole organizational
nexus is that the participants therein are credit cardholders of a company,
policyholders of an insurance company, customers of either a bank or
broker-dealer or clients of an investment adviser. The term "purchase" also
includes purchases by employee benefit plans not qualified under Section 401 of
the Code, including purchases of shares of the Fund by employees or by employers
on behalf of employees, by means of a payroll deduction plan or otherwise.
Purchases by such company or non-qualified employee benefit plan will qualify
for the quantity discounts discussed above only if the Fund and the Distributor
are able to realize economies of scale in sales effort and sales related expense
by means of the company, employer or plan making the Fund's Prospectus available
to individual investors or employees and forwarding investments by such persons
to the Fund and by any such employer or plan bearing the expense of any payroll
deduction plan.
 
Eligible Class A Investors
 
     Class A shares are offered to a limited group of investors and also will be
issued upon reinvestment of dividends on outstanding Class A shares. Investors
that currently own Class A shares of the Fund in a shareholder account,
including participants in the Merrill Lynch Blueprint(SM) program, are entitled
to purchase additional Class A shares of the Fund in that account. Certain
employer-sponsored retirement or savings
 
                                       16
<PAGE>   51
 
plans, including eligible 401(k) plans, may purchase Class A shares at net asset
value provided such plans meet the required minimum number of eligible employees
or required amount of assets advised by MLAM or any of its affiliates. Class A
shares are available at net asset value to corporate warranty insurance reserve
fund programs and U.S. branches of foreign banking institutions provided that
the program or branch has $3 million or more initially invested in Select
Pricing funds. Also eligible to purchase Class A shares at net asset value are
participants in certain investment programs including TMASM Managed Trusts to
which Merrill Lynch Trust Company provides discretionary trustee services,
collective investment trusts for which Merrill Lynch Trust Company serves as
trustee and purchases made in connection with certain fee-based programs. In
addition, Class A shares are offered at net asset value to ML & Co. and its
subsidiaries and their directors and employees and to members of the Boards of
MLAM-advised investment companies, including the Fund. Certain persons who
acquired shares of certain MLAM-advised closed-end funds in their initial
offerings who wish to reinvest the net proceeds from a sale of their closed-end
fund shares of common stock in shares of the Fund also may purchase Class A
shares of the Fund if certain conditions set forth in the Statement of
Additional Information are met (for closed-end funds that commenced operations
prior to October 21, 1994). In addition, Class A shares of the Fund and certain
other Select Pricing Funds are offered at net asset value to shareholders of
Merrill Lynch Senior Floating Rate Fund, Inc. and, if certain conditions set
forth in the Statement of Additional Information are met, to shareholders of
Merrill Lynch Municipal Strategy Fund, Inc. and Merrill Lynch High Income
Municipal Bond Fund, Inc. who wish to reinvest the net proceeds from a sale of
certain of their shares of common stock pursuant to a tender offer conducted by
such funds in shares of the Fund and certain other Select Pricing Funds.
 
     Investors are advised that only Class A and Class D shares may be available
for purchase through securities dealers, other than Merrill Lynch, that are
eligible to sell shares.

* Formerly Capital Shares.
 
     The Distributor may reallow discounts to selected dealers and retain the
balance over such discounts. At times the Distributor may reallow the entire
sales charge to such dealers. Since securities dealers selling Class A and
Class D shares of the Fund will receive a concession equal to most of the sales
charge, they may be deemed to be underwriters under the Securities Act.
 
Reduced Initial Sales Charges
 
     Reinvested Dividends and Capital Gains.  No initial sales charges are
imposed upon Class A and Class D shares issued as a result of the automatic
reinvestment of dividends or capital gains distributions.
 
     Right of Accumulation.  Reduced sales charges are applicable through a
right of accumulation under which eligible investors are permitted to purchase
shares of the Fund subject to an initial sales charge at the
 
                                       17
<PAGE>   52
 
offering price applicable to the total of (a) the public offering price of the
shares then being purchased plus (b) an amount equal to the then current net
asset value or cost, whichever is higher, of the purchaser's combined holdings
of all classes of shares of the Fund and of any other Select Pricing Funds. For
any such right of accumulation to be made available, the Distributor must be
provided at the time of purchase, by the purchaser or the purchaser's securities
dealer, with sufficient information to permit confirmation of qualification.
Acceptance of the purchase order is subject to such confirmation. The right of
accumulation may be amended or terminated at any time. Shares held in the name
of a nominee or custodian under pension, profit-sharing or other employee
benefit plans may not be combined with other shares to qualify for the right of
accumulation.
 
     Letter of Intent.  Reduced sales charges are applicable to purchases
aggregating $25,000 or more of the Class A or Class D shares of the Fund or any
Select Pricing Funds made within a 13-month period starting with the first
purchase pursuant to a Letter of Intent. The Letter of Intent is available only
to investors whose accounts are established and maintained at the Fund's
Transfer Agent. The Letter of Intent is not available to employee benefit plans
for which Merrill Lynch provides plan participant recordkeeping services. The
Letter of Intent is not a binding obligation to purchase any amount of Class A
or Class D shares; however, its execution will result in the purchaser paying a
lower sales charge at the appropriate quantity purchase level. A purchase not
originally made pursuant to a Letter of Intent may be included under a
subsequent Letter of Intent executed within 90 days of such purchase if the
Distributor is informed in writing of this intent within such 90-day period. The
value of Class A and Class D shares of the Fund and of other Select Pricing
Funds presently held, at cost or maximum offering price (whichever is higher),
on the date of the first purchase under the Letter of Intent, may be included as
a credit toward the completion of such Letter, but the reduced sales charge
applicable to the amount covered by such Letter will be applied only to new
purchases. If the total amount of shares does not equal the amount stated in the
Letter of Intent (minimum of $25,000), the investor will be notified and must
pay, within 20 days of the expiration of such Letter, the difference between the
sales charge on the Class A or Class D shares purchased at the reduced rate and
the sales charge applicable to the shares actually purchased through the Letter.
Class A or Class D shares equal to at least 5.0% of the intended amount will be
held in escrow during the 13-month period (while remaining registered in the
name of the purchaser) for this purpose. The first purchase under the Letter of
Intent must be at least 5.0% of the dollar amount of such Letter. If a purchase
during the term of such Letter would otherwise be subject to a further reduced
sales charge based on the right of accumulation, the purchaser will be entitled
on that purchase and subsequent purchases to the further reduced percentage
sales charge that would be applicable to a single purchase equal to the total
dollar value of the Class A or Class D shares then being purchased under such
Letter, but there will be no retroactive reduction of the sales charge on any
previous purchase.
 
     The value of any shares redeemed or otherwise disposed of by the purchaser
prior to termination or completion of the Letter of Intent will be deducted from
the total purchases made under such Letter. An exchange from the Summit Cash
Reserves Fund into the Fund that creates a sales charge will count toward
completing a new or existing Letter of Intent from the Fund.
 
     Merrill Lynch Blueprint(SM) Program.  Class D shares of the Fund are
offered to participants in the Merrill Lynch Blueprint(SM) Program
("Blueprint"). In addition, participants in Blueprint who own Class A shares of
the Fund may purchase additional Class A shares of the Fund through Blueprint.
The Blueprint Program is directed to small investors, group Individual
Retirement Accounts ("IRAs") and participants in certain affinity groups such as
credit unions, trade associations and benefit plans. Investors placing orders to
purchase Class A or Class D shares of the Fund through Blueprint will acquire
the Class A or Class D shares at net asset value plus a sales charge calculated
in accordance with the Blueprint sales charge schedule (i.e., up to $300 at
4.25%, from $300.01 to $5,000 at 3.25% plus $300 and $5,000.01 or more at the
standard sales charge rates disclosed in the Prospectus). In addition, Class A
and Class D shares of the Fund are being offered at net asset value plus a sales
charge of 0.50% for corporate or group IRA programs placing orders to purchase
their Class A or Class D shares through Blueprint. Services available to Class A
and Class D investors through Blueprint, including exchange privileges, may
differ from those available to other investors in Class A or Class D shares.

     Class A and Class D shares are offered at net asset value to Blueprint
participants through the Merrill Lynch Directed IRA Rollover Program ("IRA
Rollover Program") available from Merrill Lynch Business Financial Services, a
business unit of Merrill Lynch. The IRA Rollover Program is available to
custodian rollover assets from employee-sponsored retirement and savings plans
whose trustee and/or plan sponsor has entered into the Merrill Lynch Directed
IRA Rollover Program Service Agreement.
 
     Orders for purchases and redemptions of Class A or Class D shares of the
Fund may be grouped for execution purposes which, in some circumstances, may
involve the execution of such orders two business days following the day such
orders are placed. The minimum initial purchase price is $100, with a $50
minimum for subsequent purchases through Blueprint. There are no minimum initial
or subsequent purchase requirements for participants who are part of an
automatic investment plan. Additional information concerning purchases through
Blueprint, including any annual fees and transaction charges, is available from
Merrill Lynch, Pierce, Fenner & Smith Incorporated, The Blueprint(SM) Program,
P.O. Box 30441, New Brunswick, New Jersey 08989-0441.
 
     TMA(SM) Managed Trusts.  Class A shares are offered at net asset value to
TMA(SM) Managed Trusts to which Merrill Lynch Trust Company provides
discretionary trustee services.
 
     Employee Access(SM) Accounts.  Provided applicable threshold requirements
are met, either Class A or Class D shares are offered at net asset value to
Employee Access(SM) Accounts available through authorized employers. The initial
minimum investment for such accounts is $500, except that the initial minimum
investment for shares purchased for such accounts pursuant to the Automatic
Investment Program is $50.
 
     Purchase Privilege of Certain Persons.  Directors of the Fund, members of
the Boards of other MLAM-advised funds, ML & Co. and its subsidiaries (the term
"subsidiaries," when used herein with respect to ML & Co., includes MLAM, FAM
and certain other entities directly or indirectly wholly owned and controlled by
ML & Co.) and their directors and employees, and any trust, pension,
profit-sharing or other benefit plan for such persons, may purchase Class A
shares of the Fund at net asset value.
 
     Class D shares of the Fund are offered at net asset value, without a sales
charge, to an investor that has a business relationship with a Financial
Consultant who joined Merrill Lynch from another investment firm within six
months prior to the date of purchase by such investor, if the following
conditions are satisfied: first, the investor must advise Merrill Lynch that it
will purchase Class D shares of the Fund with proceeds from a redemption of
shares of a mutual fund that was sponsored by the Financial Consultant's
previous firm and was subject to a sales charge either at the time of purchase
or on a deferred basis; and, second, the investor must establish that such
redemption had been made within 60 days prior to the investment in the Fund and
the proceeds from the redemption had been maintained in the interim in cash or a
money market fund.
 
     Class D shares of the Fund are also offered at net asset value, without a
sales charge, to an investor that has a business relationship with a Merrill
Lynch Financial Consultant and that has invested in a mutual fund sponsored by a
non-Merrill Lynch company for which Merrill Lynch has served as a selected
dealer and where Merrill Lynch has either received or given notice that such
arrangement will be terminated ("notice") if the following conditions are
satisfied: first, the investor must purchase Class D shares of the Fund with
proceeds from a redemption of shares of such other mutual fund and the shares of
such other fund were subject to a sales charge either at the time of purchase or
on a deferred basis; and, second, such purchase of Class D shares must be made
within 90 days after such notice.
 
     Class D shares of the Fund are offered at net asset value, without a sales
charge, to an investor that has a business relationship with a Merrill Lynch
Financial Consultant and that has invested in a mutual fund for which Merrill
Lynch has not served as a selected dealer if the following conditions are
satisfied: first, the investor must advise Merrill Lynch that it will purchase
Class D shares of the Fund with proceeds from the redemption of shares of such
other mutual fund and that such shares have been outstanding for a period of no
less than six months; and, second, such purchase of Class D shares must be made
within 60 days after the redemption and the proceeds from the redemption must be
maintained in the interim in cash or a money market fund.

     Closed-End Fund Investment Option.  Class A shares of the Fund and certain
other Select Pricing Funds ("Eligible Class A Shares") are offered at net asset
value to shareholders of certain closed-end funds advised by FAM or MLAM who
purchased such closed-end fund shares prior to October 21, 1994 (the date the
Merrill Lynch Select Pricing(SM) System commenced operations) and wish to
reinvest the net proceeds from a sale of their closed-end fund shares of common
stock in Eligible Class A Shares, if the conditions set forth below are
satisfied. Alternatively, closed-end fund shareholders who purchased such shares
on or after October 21, 1994 and wish to reinvest the net proceeds from a sale
of their closed-end fund shares are offered Class A shares (if eligible to buy
Class A shares) or Class D shares of the Fund and other Select Pricing Funds
("Eligible Class D Shares"), if the following conditions are met. First, the
sale of closed-end fund shares must be made through Merrill Lynch, and the net
proceeds therefrom must be immediately reinvested in Eligible Class A or
Eligible Class D Shares. Second, the closed-end fund shares must either have
been acquired in the initial public offering or be shares representing dividends
from shares of common stock acquired in such offering. Third, the closed-end
fund 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.
 
     Shareholders of certain MLAM-advised continuously offered closed-end funds
may reinvest at net asset value the net proceeds from a sale of certain shares
of common stock of such funds in shares of the Fund. Upon exercise of this
investment option, shareholders of Merrill Lynch Senior Floating Rate Fund, Inc.
will receive Class A shares of the Fund and shareholders of Merrill Lynch
Municipal Strategy Fund, Inc. and Merrill Lynch High Income Municipal Bond Fund,
Inc. will receive Class D shares of the Fund, except that shareholders already
owning Class A shares of the Fund will be eligible to purchase additional Class
A shares pursuant to this option, if such additional Class A shares will be held
in the same account as the existing Class A shares and the other requirements
pertaining to the reinvestment privilege are met. In order to exercise this
investment option, a shareholder of one of the above-referenced continuously
offered closed-end funds (an "eligible fund") must sell his or her shares of
common stock of the eligible fund (the "eligible shares") back to the eligible
fund in connection with a tender offer conducted by the eligible fund and
reinvest the proceeds immediately in the designated class of shares of the Fund.
This investment option is available only with respect to eligible shares as to
which no Early Withdrawal Charge or CDSC (each as defined in the eligible fund's
prospectus) is applicable. Purchase orders from eligible fund shareholders
wishing to exercise this investment option will be accepted only on the day that
the related tender offer terminates and will be effected at the net asset value
of the designated class of the Fund on such day.
 
     Acquisition of Certain Investment Companies.  The public offering price of
Class D shares may be reduced to the net asset value per Class D share in
connection with the acquisition of the assets of or merger or consolidation with
a personal holding company or a public or private investment company. The value
of the assets or company acquired in a tax-free transaction may be adjusted in
appropriate cases to reduce possible adverse tax consequences to the Fund that
might result from an acquisition of assets having net unrealized appreciation
that is disproportionately higher at the time of acquisition than the realized
or unrealized appreciation of the Fund. The issuance of Class D shares for
consideration other than cash is limited to bona fide reorganizations, statutory
mergers or other acquisitions of portfolio securities that (i) meet the
investment objectives and policies of the Fund; (ii) are acquired for investment
and not for resale (subject to the understanding that the disposition of the
Fund's portfolio securities shall at all times remain within its control); and
(iii) are liquid securities, the value of which is readily ascertainable, which
are not restricted as to transfer either by law or liquidity of market (except
that the Fund may acquire through such transactions restricted or illiquid
securities to the extent the Fund does not exceed the applicable limits on
acquisition of such securities set forth under "Investment Objective and
Policies" herein).
 
     Reductions in or exemptions from the imposition of a sales load are due to
the nature of the investors and/or the reduced sales efforts that will be needed
in obtaining such investments.
 
EMPLOYER-SPONSORED RETIREMENT OR SAVINGS PLANS AND CERTAIN OTHER ARRANGEMENTS
 
     Certain employer-sponsored retirement or savings plans and certain other
arrangements may purchase Class A or Class D shares at net asset value, based on
the number of employees or number of employees
                                       20
<PAGE>   55
 
eligible to participate in the plan, the aggregate amount invested by the plan
in specified investments and/or the services provided by Merrill Lynch to the
plan. Certain other plans may purchase Class B shares with a waiver of the CDSC
upon redemption, based on similar criteria. Such Class B shares will convert
into Class D shares approximately ten years after the plan purchases the first
share of any Select Pricing Fund. Minimum purchase requirements may be waived or
varied for such plans. Additional information regarding purchases by
employer-sponsored retirement or savings plans and certain other arrangements is
available toll-free from Merrill Lynch Business Financial Services at (800)
237-7777.
 
DEFERRED SALES CHARGE ALTERNATIVES -- CLASS B AND CLASS C SHARES
 
     Investors choosing the deferred sales charge alternatives should consider
Class B shares if they intend to hold their shares for an extended period of
time and Class C shares if they are uncertain as to the length of time they
intend to hold their assets in Select Pricing Funds.
 
     Because no initial sales charges are deducted at the time of the purchase,
Class B and Class C shares provide the benefit of putting all of the investor's
dollars to work from the time the investment is made. The deferred sales charge
alternatives may be particularly appealing to investors that do not qualify for
the reduction in initial sales charges. Both Class B and Class C shares are
subject to ongoing account maintenance fees and distribution fees; however, the
ongoing account maintenance and distribution fees potentially may be offset to
the extent any return is realized on the additional funds initially invested in
Class B or Class C shares. In addition, Class B shares will be converted into
Class D shares of the Fund after a conversion period of approximately eight
years, and thereafter investors will be subject to lower ongoing fees.
 
     The public offering price of Class B and Class C shares for investors
choosing the deferred sales charge alternatives is the next determined net asset
value per share without the imposition of a sales charge at the time of
purchase. See "Pricing of Shares -- Determination of Net Asset Value" below.
 
Contingent Deferred Sales Charges -- Class B Shares
 
     Class B shares that are redeemed within four years of purchase may be
subject to a CDSC at the rates set forth below charged as a percentage of the
dollar amount subject thereto. In determining whether a CDSC is applicable to a
redemption, the calculation will be determined in the manner that results in the
lowest applicable rate being charged. The charge will be assessed on an amount
equal to the lesser of the proceeds of redemption or the cost of the shares
being redeemed. Accordingly, no CDSC will be imposed on increases in net asset
value above the initial purchase price. In addition, no CDSC will be assessed on
shares derived from reinvestment of dividends or capital gains distributions. It
will be assumed that the redemption is first of shares held for over four years
or shares acquired pursuant to reinvestment of dividends or distributions and
then of shares held longest during the four-year period. A transfer of shares
from a shareholder's account to another account will be assumed to be made in
the same order as a redemption.
 
     The following table sets forth the Class B CDSC:

     To provide an example, assume an investor purchased 100 shares at $10 per
share (at a cost of $1,000) and in the third year after purchase, the net asset
value per share is $12 and, during such time, the investor has acquired 10
additional shares upon dividend reinvestment. If at such time the investor makes
his or her first redemption of 50 shares (proceeds of $600), 10 shares will not
be subject to a CDSC because of dividend reinvestment. With respect to the
remaining 40 shares, the charge is applied only to the original cost of $10 per
 
                                       21
<PAGE>   56
 
share and not to the increase in net asset value of $2 per share. Therefore,
$400 of the $600 redemption proceeds will be charged at a rate of 2.0% (the
applicable rate in the third year after purchase).
 
     The Class B CDSC is waived on redemptions of shares in connection with
certain post-retirement withdrawals from an Individual Retirement Account
("IRA") or other retirement plan or following death or disability (as defined in
the Internal Revenue Code of 1986, as amended (the "Code")) of a shareholder
(including one who owns the Class B shares as joint tenant with his or her
spouse), provided the redemption is requested within one year of the death or
initial determination of disability. The Class B CDSC also is waived on
redemptions of shares by certain eligible 401(a) and eligible 401(k) plans and
in connection with certain group plans placing orders through the Merrill Lynch
Blueprint(SM) Program. The CDSC is also waived for any Class B shares that are
purchased by eligible 401(a) or eligible 401(k) plans that are rolled over into
a Merrill Lynch or Merrill Lynch Trust Company custodied IRA and held in such
account at the time of redemption. The Class B CDSC is also waived for any Class
B shares purchased within qualifying Employee Access(SM) Accounts. The Class B
CDSC is also waived for any Class B shares that are purchased by a Merrill Lynch
rollover IRA that was funded by a rollover from a terminated 401(k) plan managed
by the MLAM Private Portfolio Group and held in such account at the time of
redemption. The terms of the CDSC may be modified in connection with certain
fee-based programs. See "Shareholder Services -- Fee-Based Programs."
 
     Merrill Lynch Blueprint(SM) Program.  Class B shares are offered to certain
participants in Blueprint. Blueprint is directed to small investors, group IRAs
and participants in certain affinity groups such as trade associations and
credit unions. Class B shares of the Fund are offered through Blueprint only to
members of certain affinity groups. The CDSC is waived in connection with
purchase orders placed through Blueprint. Services, including the exchange
privilege, available to Class B investors through Blueprint, however, may differ
from those available to other Class B investors. Orders for purchases and
redemptions of Class B shares of the Fund will be grouped for execution purposes
which, in some circumstances, may involve the execution of such orders two
business days following the day such orders are placed. The minimum initial
purchase price is $100, with a $50 minimum for subsequent purchases through
Blueprint. There is no minimum initial or subsequent purchase requirement for
investors who are part of a Blueprint automatic investment plan. Additional
information concerning these Blueprint programs, including any annual fees or
transaction charges, is available from Merrill Lynch, Pierce, Fenner & Smith
Incorporated, The Blueprint(SM) Program, P.O. Box 30441, New Brunswick, New
Jersey 08989-0441.
 
     Conversion of Class B Shares to Class D Shares.  After approximately eight
years (the "Conversion Period"), Class B shares will be converted automatically
into Class D shares of the Fund. Class D shares are subject to an ongoing
account maintenance fee of 0.25% of net assets but are not subject to the
distribution fee that is borne by Class B shares. Automatic conversion of Class
B shares into Class D shares will occur at least once each month (on the
"Conversion Date") on the basis of the relative net asset value of the shares of
the two classes on the Conversion Date, without the imposition of any sales
load, fee or other charge. Conversion of Class B shares to Class D shares will
not be deemed a purchase or sale of the shares for Federal income tax purposes.
 
     In addition, shares purchased through reinvestment of dividends on Class B
shares also will convert automatically to Class D shares. The Conversion Date
for dividend reinvestment shares will be calculated taking into account the
length of time the shares underlying such dividend reinvestment shares were
outstanding. If at the Conversion Date the conversion of Class B shares to Class
D shares of the Fund in a single account will result in less than $50 worth of
Class B shares being left in the account, all of the Class B shares of the Fund
held in the account on the Conversion Date will be converted to Class D shares
of the Fund.
 
     In general, Class B shares of equity Select Pricing Funds will convert
approximately eight years after initial purchase and Class B shares of taxable
and tax-exempt fixed income Select Pricing Funds will convert approximately ten
years after initial purchase. If, during the Conversion Period, a shareholder
exchanges Class B shares with an eight-year Conversion Period for Class B shares
with a ten-year Conversion Period, or vice versa, the Conversion Period
applicable to the Class B shares acquired in the exchange will apply and the
holding period for the shares exchanged will be tacked on to the holding period
for the shares acquired. The
 
                                       22
<PAGE>   57
 
conversion period also may be modified for investors that participate in certain
fee-based programs. See "Shareholder Services -- Fee-Based Programs."
 
     Class B shareholders of the Fund exercising the exchange privilege
described under "Shareholder Services -- Exchange Privilege" will continue to be
subject to the Fund's CDSC schedule if such schedule is higher than the CDSC
schedule relating to the Class B shares acquired as a result of the exchange.
 
     Share certificates for Class B shares of the Fund to be converted must be
delivered to the Transfer Agent at least one week prior to the Conversion Date
applicable to those shares. In the event such certificates are not received by
the Transfer Agent at least one week prior to the Conversion Date, the related
Class B shares will convert to Class D shares on the next scheduled Conversion
Date after such certificates are delivered.
 
Contingent Deferred Sales Charges -- Class C Shares
 
   
     Class C shares that are redeemed within one year of purchase may be subject
to a 1.0% CDSC charged as a percentage of the dollar amount subject thereto. In
determining whether a Class C CDSC is applicable to a redemption, the
calculation will be determined in the manner that results in the lowest possible
rate being charged. The charge will be assessed on an amount equal to the lesser
of the proceeds of redemption or the cost of the shares being redeemed.
Accordingly, no Class C CDSC will be imposed on increases in net asset value
above the initial purchase price. In addition, no Class C CDSC will be assessed
on shares derived from reinvestment of dividends or capital gains distributions.
It will be assumed that the redemption is first of shares held for over one year
or shares acquired pursuant to reinvestment of dividends or distributions and
then of shares held longest during the one-year period. The charge will not be
applied to dollar amounts representing an increase in the net asset value since
the time of purchase. A transfer of shares from a shareholder's account to
another account will be assumed to be made in the same order as a redemption.
The Class C CDSC may be waived in connection with certain fee-based programs,
involuntary termination of an account in which Fund shares are held and
withdrawals through the Merrill Lynch Systematic Withdrawal Plan. See
"Shareholder Services -- Fee-Based Programs."

+ Commencement of operations
    
 
     Merrill Lynch compensates its Financial Consultants for selling Class B and
Class C shares at the time of purchase from its own funds. Proceeds from the
CDSC and the distribution fee are paid to the Distributor and are used in whole
or in part by the Distributor to defray the expenses of dealers (including
Merrill Lynch) related to providing distribution-related services to the Fund in
connection with the sale of the Class B and Class C shares, such as the payment
of compensation to financial consultants for selling Class B and Class C shares
from the dealer's own funds. The combination of the CDSC and the ongoing
distribution fee facilitates the ability of the Fund to sell the Class B and
Class C shares without a sales charge being deducted at the time of purchase.
See "Distribution Plans" below. Imposition of the CDSC and the distribution fee
on Class B and Class C shares is limited by the NASD asset-based sales charge
rule. See "Limitations on the Payment of Deferred Sales Charges" below.

DISTRIBUTION PLANS
 
     Reference is made to "Fees and Expenses" in the Prospectus for certain
information with respect to the separate distribution plans for Class B, Class C
and Class D shares pursuant to Rule 12b-1 under the Investment Company Act (each
a "Distribution Plan") with respect to the account maintenance and/or
distribution fees paid by the Fund to the Distributor with respect to such
classes.
 
     The Distribution Plans for Class B, Class C and Class D shares each
provides that the Fund pays the Distributor an account maintenance fee relating
to the shares of the relevant class, accrued daily and paid monthly, at the
annual rate of 0.25%, of the average daily net assets of the Fund attributable
to shares of the relevant class in order to compensate the Distributor and
Merrill Lynch (pursuant to a sub-agreement) in connection with account
maintenance activities with respect to Class B, Class C and Class D shares. Each
of those classes has exclusive voting rights with respect to the Distribution
Plan adopted with respect to such class pursuant to which account maintenance
and/or distribution fees are paid (except that Class B shareholders may vote
upon any material changes to expenses charged under the Class D Distribution
Plan).
 
     The Distribution Plans for Class B and Class C shares each provides that
the Fund also pays the Distributor a distribution fee relating to the shares of
the relevant class, accrued daily and paid monthly, at the annual rate of 0.75%,
of the average daily net assets of the Fund attributable to the shares of the
relevant class in order to compensate the Distributor and Merrill Lynch
(pursuant to a sub-agreement) for providing shareholder and distribution
services and bearing certain distribution-related expenses of the Fund,
including payments to financial consultants for selling Class B and Class C
shares of the Fund. The Distribution Plans relating to Class B and Class C
shares are designed to permit an investor to purchase Class B and Class C shares
through dealers without the assessment of an initial sales charge and at the
same time permit the dealer to compensate its financial consultants in
connection with the sale of the Class B and Class C shares.
 
     The Fund's Distribution Plans are subject to the provisions of Rule 12b-1
under the Investment Company Act. In their consideration of each Distribution
Plan, the Directors must consider all factors they deem relevant, including
information as to the benefits of the Distribution Plan to the Fund and each
related class of shareholders. Each Distribution Plan further provides that, so
long as the Distribution Plan remains in effect, the selection and nomination of
non-interested Directors shall be committed to the discretion of the non-
interested Directors then in office. In approving each Distribution Plan in
accordance with Rule 12b-1, the non-interested Directors concluded that there is
reasonable likelihood that each Distribution Plan will benefit the Fund and its
related class of shareholders. Each Distribution Plan can be terminated at any
time, without penalty, by the vote of a majority of the non-interested Directors
or by the vote of the holders of a majority of the outstanding related class of
voting securities of the Fund. A Distribution Plan cannot be amended to increase
materially the amount to be spent by the Fund without the approval of the
related class of shareholders and all material amendments are required to be
approved by the vote of Directors, including a majority of the non-interested
Directors who have no direct or indirect financial interest in the Distribution
Plan, cast in person at a meeting called for that purpose. Rule 12b-1 further
requires that the Fund preserve copies of the Distribution Plan and any report
made pursuant to such plan for a period of not less than six years from the date
of the Distribution Plan or such report, the first two years in an easily
accessible place.
 
     Among other things, each Distribution Plan provides that the Distributor
shall provide and the Directors shall review quarterly reports of the
disbursement of the account maintenance and/or distribution fees paid to the
Distributor. Payments under the Distribution Plans are based on a percentage of
average daily net assets attributable to the shares regardless of the amount of
expenses incurred and, accordingly, distribution-related revenues from the
Distribution Plans may be more or less than distribution-related expenses.
Information with respect to the distribution-related revenues and expenses is
presented to the Directors for their consideration in connection with their
deliberations as to the continuance of the Class B and Class C Distribution
Plans annually, as of December 31 of each year, on a "fully allocated accrual"
basis and quarterly on a "direct expense and revenue/cash" basis. On the fully
allocated accrual basis, revenues consist of the account maintenance fees,
distribution fees, the CDSCs and certain other related revenues, and expenses
consist of financial consultant compensation, branch office and regional
operation center selling and transaction processing expenses, advertising, sales
promotion and marketing expenses, corporate overhead and interest
 
                                       24
<PAGE>   59
 
expense. On the direct expense and revenue/cash basis, revenues consist of the
account maintenance fees, distribution fees and CDSCs and the expenses consist
of financial consultant compensation.
 
   
     As of December 31, 1997, the last date for which fully allocated accrual
data is available, for Class B shares, the fully allocated accrual expenses of
the Distributor and Merrill Lynch for the period since August 4, 1997
(commencement of operations as an open-end investment company) exceeded the
fully allocated accrual revenues by approximately $327,000 (3.01% of Class B net
assets at that date). As of August 31, 1998, for Class B shares, direct cash
expenses for the period since August 4, 1997 (commencement of operations as an
open-end investment company) exceeded direct cash revenues by $3,113,561 (13.03%
of Class B net assets at that date). As of December 31, 1997, for Class C
shares, the fully allocated accrual expenses incurred by the Distributor and
Merrill Lynch for the period since August 4, 1997 (commencement of operations as
an open-end investment company) exceeded the fully allocated accrual revenues by
approximately $50,000 (3.34% of Class C net assets at that date). As of August
31, 1998, for Class C shares, direct cash revenues for the period since August
4, 1997 (commencement of operations as an open-end investment company) exceeded
direct cash expenses by $105,384 (2.05% of Class C net assets at that date). The
foregoing includes the operations of Merrill Lynch Global Convertible Fund,
Inc., which the Fund acquired effective May 8, 1998.
    
 
     For the fiscal year ended August 31, 1998, the Fund paid the Distributor
$158,876 pursuant to the Class B Distribution Plan (based on average daily net
assets subject to such Class B Distribution Plan of approximately $15.8
million), all of which was paid to Merrill Lynch for providing account
maintenance and distribution-related activities and services in connection with
Class B shares. For the fiscal year ended August 31, 1998, the Fund paid the
Distributor $31,270 pursuant to the Class C Distribution Plan (based on average
daily net assets subject to such Class C Distribution Plan of approximately $3.1
million), all of which was paid to Merrill Lynch for providing account
maintenance and distribution-related activities and services in connection with
Class C shares. For the fiscal year ended August 31, 1998, the Fund paid the
Distributor $10,136 pursuant to the Class D Distribution Plan (based on average
daily net assets subject to such Class D Distribution Plan of approximately $4.0
million), all of which was paid to Merrill Lynch for providing account
maintenance activities in connection with Class D shares.
 
LIMITATIONS ON THE PAYMENT OF DEFERRED SALES CHARGES
 
     The maximum sales charge rule in the Conduct Rules of the NASD imposes a
limitation on certain asset-based sales charges such as the distribution fee and
the CDSC borne by the Class B and Class C shares but not the account maintenance
fee. The maximum sales charge rule is applied separately to each class. As
applicable to the Fund, the maximum sales charge rule limits the aggregate of
distribution fee payments and CDSCs payable by the Fund to (1) 6.25% of eligible
gross sales of Class B shares and Class C shares, computed separately (defined
to exclude shares issued pursuant to dividend reinvestments and exchanges), plus
(2) interest on the unpaid balance for the respective class, computed
separately, at the prime rate plus 1% (the unpaid balance being the maximum
amount payable minus amounts received from the payment of the distribution fee
and the CDSC). In connection with the Class B shares, the Distributor has
voluntarily agreed to waive interest charges on the unpaid balance in excess of
0.50% of eligible gross sales. Consequently, the maximum amount payable to the
Distributor (referred to as the "voluntary maximum") in connection with the
Class B shares is 6.75% of eligible gross sales. The Distributor retains the
right to stop waiving the interest charges at any time. To the extent payments
would exceed the voluntary maximum, the Fund will not make further payments of
the distribution fee with respect to Class B shares and any CDSCs will be paid
to the Fund rather than to the Distributor; however, the Fund will continue to
make payments of the account maintenance fee. In certain circumstances the
amount payable pursuant to the voluntary maximum may exceed the amount payable
under the NASD formula. In such circumstances payment in excess of the amount
payable under the NASD formula will not be made.
 
     The following table sets forth comparative information as of August 31,
1998 with respect to the Class B and Class C shares of the Fund indicating the
maximum allowable payments that can be made under the
 
                                       25

(2) Interest is computed on a monthly basis based upon the prime rate, as
    reported in The Wall Street Journal, plus 1.0%, as permitted under the NASD
    Rule.
(3) Consists of CDSC payments, distribution fee payments and accruals. See "What
    are the Fund's fees and expenses?" in the Prospectus. This figure may
    include CDSCs that were deferred when a shareholder redeemed shares prior to
    the expiration of the applicable CDSC period and invested the proceeds,
    without the imposition of a sales charge, in Class A shares in conjunction
    with the shareholder's participation in the Merrill Lynch Mutual Fund
    Advisor (Merrill Lynch MFA(SM)) Program (the "MFA Program"). The CDSC is
    booked as a contingent obligation that may be payable if the shareholder
    terminates participation in the MFA Program.
(4) Provided to illustrate the extent to which the current level of distribution
    fee payments (not including any CDSC payments) is amortizing the unpaid
    balance. No assurance can be given that payments of the distribution fee
    will reach either the voluntary maximum (with respect to Class B shares) or
    the NASD maximum (with respect to Class B and Class C shares).
 
                              REDEMPTION OF SHARES
 
     Reference is made to "How to Buy, Sell, Transfer and Exchange Shares" in
the Prospectus.
 
   
     The Fund is required to redeem for cash all shares of the Fund upon receipt
of a written request in proper form. The redemption price is the net asset value
per share next determined after the initial receipt of proper notice of
redemption. Except for any CDSC that may be applicable, there will be no charge
for redemption if the redemption request is sent directly to the Transfer Agent.
Shareholders liquidating their holdings will receive upon redemption all
dividends reinvested through the date of redemption.
    
 
     The right to redeem shares or to receive payment with respect to any such
redemption may be suspended for more than seven days only for any period during
which trading on the NYSE is restricted as determined by the Commission or the
NYSE is closed (other than customary weekend and holiday closings), for any
period during which an emergency exists as defined by the Commission as a result
of which disposal of portfolio securities or determination of the net asset
value of the Fund is not reasonably practicable, and for such other periods as
the Commission may by order permit for the protection of shareholders of the
Fund.
 
   
     The value of shares at the time of redemption may be more or less than the
shareholder's cost, depending in part on the market value of the securities held
by the Fund at such time.
    
 
                                       26
<PAGE>   61
 
REDEMPTION
 
     A shareholder wishing to redeem shares held with the Transfer Agent may do
so without charge by tendering the shares directly to the Transfer Agent at
Financial Data Services, Inc., P.O. Box 45289, Jacksonville, Florida 32232-5289.
Redemption requests delivered other than by mail should be delivered to
Financial Data Services, Inc., 4800 Deer Lake Drive East, Jacksonville, Florida
32246-6484. Proper notice of redemption in the case of shares deposited with the
Transfer Agent may be accomplished by a written letter requesting redemption.
Proper notice of redemption in the case of shares for which certificates have
been issued may be accomplished by a written letter as noted above accompanied
by certificates for the shares to be redeemed. Redemption requests should not be
sent to the Fund. The redemption request in either event requires the
signature(s) of all persons in whose name(s) the shares are registered, signed
exactly as such name(s) appear(s) on the Transfer Agent's register. The
signature(s) on the redemption requests must be guaranteed by an "eligible
guarantor institution" as such is defined in Rule 17Ad-15 under the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), the existence and
validity of which may be verified by the Transfer Agent through the use of
industry publications. Notarized signatures are not sufficient. In certain
instances, the Transfer Agent may require additional documents such as, but not
limited to, trust instruments, death certificates, appointments as executor or
administrator, or certificates of corporate authority. For shareholders
redeeming directly with the Transfer Agent, payments will be mailed within seven
days of receipt of a proper notice of redemption.
 
     At various times the Fund may be requested to redeem shares for which it
has not yet received good payment (e.g., cash, Federal funds or certified check
drawn on a United States bank). The Fund may delay or cause to be delayed the
mailing of a redemption check until such time as it has assured itself that good
payment (e.g., cash, Federal funds or certified check drawn on a United States
bank) has been collected for the purchase of such Fund shares, which will not
exceed 10 days.
 
REPURCHASE
 
     The Fund also will repurchase Fund shares through a shareholder's listed
securities dealer. The Fund normally will accept orders to repurchase Fund
shares by wire or telephone from dealers for their customers at the net asset
value next computed after the order is placed. Shares will be priced at the net
asset value calculated on the day the request is received, provided that the
request for repurchase is submitted to the dealer prior to fifteen minutes after
the regular close of business on the NYSE (generally, the NYSE closes at 4:00
p.m., Eastern time) on the day received, and such request is received by the
Fund from such dealer not later than 30 minutes after the close of business on
the NYSE on the same day. Dealers have the responsibility of submitting such
repurchase requests to the Fund not later than 30 minutes after the close of
business on the NYSE, in order to obtain that day's closing price.
 
     The foregoing repurchase arrangements are for the convenience of
shareholders and do not involve a charge by the Fund (other than any applicable
CDSC). Securities firms that do not have selected dealer agreements with the
Distributor, however, may impose a transaction charge on the shareholder for
transmitting the notice of repurchase to the Fund. Merrill Lynch may charge its
customers a processing fee (presently $5.35) to confirm a repurchase of shares
to such customers. Repurchases made directly through the Transfer Agent on
accounts held at the Transfer Agent are not subject to the processing fee. The
Fund reserves the right to reject any order for repurchase, which right of
rejection might adversely affect shareholders seeking redemption through the
repurchase procedure. However, a shareholder whose order for repurchase is
rejected by the Fund may redeem Fund shares as set forth above.
 
REINSTATEMENT PRIVILEGE -- CLASS A AND CLASS D SHARES
 
     Shareholders who have redeemed their Class A or Class D shares of the Fund
have a privilege to reinstate their accounts by purchasing Class A or Class D
shares, as the case may be, of the Fund at net asset value without a sales
charge up to the dollar amount redeemed. The reinstatement privilege may be
exercised by sending a notice of exercise along with a check for the amount to
be reinstated to the Transfer Agent within 30 days after the date the request
for redemption was accepted by the Transfer Agent or the Distributor.
 
                                       27
<PAGE>   62
 
Alternatively, the reinstatement privilege may be exercised through the
investor's Merrill Lynch Financial Consultant within 30 days after the date the
request for redemption was accepted by the Transfer Agent or the Distributor.
The reinstatement will be made at the net asset value per share next determined
after the notice of reinstatement is received and cannot exceed the amount of
the redemption proceeds.
 
                               PRICING OF SHARES
 
DETERMINATION OF NET ASSET VALUE
 
     Reference is made to "How Shares are Priced" in the Prospectus.
 
     The net asset value of the shares of all classes of the Fund is determined
by the Manager once daily Monday through Friday as of 15 minutes after the close
of business on the NYSE on each day the NYSE is open for trading. The NYSE
generally closes at 4:00 p.m., Eastern time. The NYSE is not open for trading on
New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday,
Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day.
 
   
     Net asset value is computed by dividing the value of the securities held by
the Fund plus any cash or other assets (including interest and dividends accrued
but not yet received) minus all liabilities (including accrued expenses) by the
total number of shares outstanding at such time, rounded to the nearest cent.
Expenses, including the fees payable to the Manager and Distributor, are accrued
daily.
    
 
     The per share net asset value of Class B, Class C and Class D shares
generally will be lower than the per share net asset value of Class A shares,
reflecting the daily expense accruals of the account maintenance, distribution
and higher transfer agency fees applicable with respect to Class B and Class C
shares, and the daily expense accruals of the account maintenance fees
applicable with respect to the Class D shares; moreover, the per share net asset
value of the Class B and Class C shares generally will be lower than the per
share net asset value of Class D shares reflecting the daily expense accruals of
the distribution fees and higher transfer agency fees applicable with respect to
Class B and Class C shares of the Fund. It is expected, however, that the per
share net asset value of the four classes will tend to converge (although not
necessarily meet) immediately after the payment of dividends or distributions,
which will differ by approximately the amount of the expense accrual
differentials between the classes.
 
     Portfolio securities that are traded on stock exchanges are valued at the
last sale price (regular way) on the exchange on which such securities are
traded, as of the close of business on the day the securities are being valued
or, lacking any sales, at the last available bid price. In cases where
securities are traded on more than one exchange, the securities are valued on
the exchange designated by or under the authority of the Board of Directors as
the primary market. Securities traded in the OTC market are valued at the last
available bid price in the OTC market prior to the time of valuation. Portfolio
securities that are traded both in the OTC market and on a stock exchange are
valued according to the broadest and most representative market. When the Fund
writes an option, the amount of the premium received is recorded on the books of
the Fund as an asset and an equivalent liability. The amount of the liability is
subsequently valued to reflect the current market value of the option written,
based upon the last sale price in the case of exchange-traded options or, in the
case of options traded in the OTC market, the last asked price. Options
purchased by the Fund are valued at their last sale price in the case of
exchange-traded options or, in the case of options traded in the OTC market, the
last bid price. Other investments, including financial futures contracts and
related options, are stated at market value. Securities and assets for which
market quotations are not readily available are valued at fair value as
determined in good faith by or under the direction of the Board of Directors of
the Fund. Such valuations and procedures will be reviewed periodically by the
Board of Directors.
 
     Generally, trading in foreign securities, as well as U.S. Government
securities and money market instruments, is substantially completed each day at
various times prior to the close of business on the NYSE. The values of such
securities used in computing the net asset value of the Fund's shares are
determined as of such times. Foreign currency exchange rates are also generally
determined prior to the close of business on the NYSE. Occasionally, events
affecting the values of such securities and such exchange rates may occur
 
                                       28
<PAGE>   63
 
between the times at which they are determined and the close of business on the
NYSE that will not be reflected in the computation of the Fund's net asset
value. If events materially affecting the value of such securities occur during
such period, then these securities will be valued at their fair value as
determined in good faith by the Directors.
 
COMPUTATION OF OFFERING PRICE PER SHARE
 
     An illustration of the computation of the offering price for Class A, Class

                             PORTFOLIO TRANSACTIONS
 
TRANSACTIONS IN PORTFOLIO SECURITIES
 
     Subject to policies established by the Board of Directors of the Fund, the
Manager is primarily responsible for the execution of the Fund's portfolio
transactions and the allocation of brokerage. In executing such transactions,
the Manager seeks to obtain the best net 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 Manager 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 group of
brokers in execution of transactions in portfolio securities. Subject to
obtaining the best price and execution, brokers who provide supplemental
investment research to the Manager may receive orders for transactions by the
Fund. Information so received will be in addition to and not in lieu of the
services required to be performed by the Manager under the Management Agreement
and the expenses of the Manager will not necessarily be reduced as a result of
the receipt of such supplemental information. It is possible that certain
supplementary investment research so received will primarily benefit one or more
other investment companies or other accounts for which investment discretion is
exercised. Conversely, the Fund may be the primary beneficiary of the research
or services received as a result of portfolio transactions effected for such
other accounts or investment companies. In addition, consistent with the Conduct
Rules of the NASD and policies established by the Board of Directors of the
Fund, the Manager may consider sales of shares of the Fund as a factor in the
selection of brokers or dealers to execute portfolio transactions for the Fund.
 
     The Fund does not use any particular broker or dealer, and brokers who
provide supplemental investment research to the Manager may receive orders for
transactions by the Fund. Such supplemental research services ordinarily consist
of assessments and analyses of the business or prospects of a company, industry
or economic
 
                                       29
<PAGE>   64
 
sector. Information so received will be in addition to and not in lieu of the
services required to be performed by the Manager under the Management Agreement.
If in the judgment of the Manager the Fund will benefit from supplemental
research services, the Manager is authorized to pay brokerage commissions to a
broker furnishing such services that are in excess of commissions that another
broker may have charged for effecting the same transaction. The expenses of the
Manager will not necessarily be reduced as a result of the receipt of such
supplemental information, and the Manager may use such information in servicing
its other accounts. Whether or not a particular broker-dealer sells shares of
the Fund neither qualifies nor disqualifies such broker-dealer to execute
transactions for the Fund.
 
     The Fund anticipates that its brokerage transactions involving securities
of companies domiciled in countries other than the United States will be
conducted primarily on the principal stock exchanges of such countries.
Brokerage commissions and other transaction costs on foreign stock exchange
transactions are generally higher than in the United States, although the Fund
will endeavor to achieve the best net results in effecting its portfolio
transactions. There is generally less governmental supervision and regulation of
foreign stock exchanges and brokers than in the United States.
 
     Foreign equity securities may be held by the Fund in the form of ADRs,
EDRs, GDRs or other securities convertible into foreign equity securities. ADRs,
EDRs and GDRs may be listed on stock exchanges, or traded in OTC markets in the
United States or Europe, as the case may be. ADRs, like other securities traded
in the United States, will be subject to negotiated commission rates.
 
   
     The Fund may invest in certain securities traded in the OTC market and
intends to deal directly with the dealers who make a market in the securities
involved, except in those circumstances in which better prices and execution are
available elsewhere. Under the Investment Company Act, persons affiliated with
the Fund and persons who are affiliated with such affiliated persons are
prohibited from dealing with the Fund as principal in the purchase and sale of
securities unless a permissive order allowing such transactions is obtained from
the Commission. Since transactions in the OTC market usually involve
transactions with dealers acting as principal for their own accounts, the Fund
will not deal with affiliated persons, including Merrill Lynch and its
affiliates, in connection with such transactions. However, an affiliated person
of the Fund may serve as its broker in OTC transactions conducted on an agency
basis provided that, among other things, the fee or commission received by such
affiliated broker is reasonable and fair compared to the fee or commission
received by non-affiliated brokers in connection with comparable transactions.
Information about the brokerage commissions paid by the Fund, including
commissions paid to Merrill Lynch, is set forth in the following table:

</TABLE>
    
 
   
     For the fiscal year ended August 31, 1998, the brokerage commissions paid
to Merrill Lynch represented 37.49% of the aggregate brokerage commissions paid
and involved 32.41% of the dollar amount of transactions involving payment of
commissions during the year. Until August 4, 1997 when the Fund converted to
open-end status, the Fund operated as a closed-end investment company and,
consequently, the brokerage commissions paid while the Fund operated as a
closed-end investment company, may not necessarily be indicative of the costs of
future brokerage commissions for the Fund.
    
 
     The Fund's ability and decisions to purchase or sell portfolio securities
may be affected by laws or regulations relating to the convertibility and
repatriation of assets. Because the shares of the Fund are redeemable on a daily
basis in United States dollars, the Fund intends to manage its portfolio so as
to give
 
                                       30
<PAGE>   65
 
reasonable assurance that it will be able to obtain United States dollars to the
extent necessary to meet anticipated redemptions. Under present conditions, it
is not believed that these considerations will have any significant effect on
its portfolio strategy.
 
     Section 11(a) of the Exchange Act generally prohibits members of the U.S.
national securities exchanges from executing exchange transactions for their
affiliates and institutional accounts that they manage unless the member (i) has
obtained prior express authorization from the account to effect such
transactions, (ii) at least annually furnishes the account with a statement
setting forth the aggregate compensation received by the member in effecting
such transactions, and (iii) complies with any rules the Commission has
prescribed with respect to the requirements of clauses (i) and (ii). To the
extent Section 11(a) would apply to Merrill Lynch acting as a broker for the
Fund in any of its portfolio transactions executed on any such securities
exchange of which it is a member, appropriate consents have been obtained from
the Fund and annual statements as to aggregate compensation will be provided to
the Fund. Securities may be held by, or be appropriate investments for, the Fund
as well as other funds or investment advisory clients of the Manager or MLAM.
 
     Because of different objectives or other factors, a particular security may
be bought for one or more clients of the Manager or an affiliate when one or
more clients of the Manager or an affiliate are selling the same security. If
purchases or sales of securities arise for consideration at or about the same
time that would involve the Fund or other clients or funds for which the Manager
or an affiliate acts as manager, transactions in such securities will be made,
insofar as feasible, for the respective funds and clients in a manner deemed
equitable to all. To the extent that transactions on behalf of more than one
client of the Manager or an affiliate during the same period may increase the
demand for securities being purchased or the supply of securities being sold,
there may be an adverse effect on price.
 
     The Board of Directors of the Fund has considered the possibility of
seeking to recapture for the benefit of the Fund brokerage commissions and other
expenses of possible portfolio transactions by conducting portfolio transactions
through affiliated entities. For example, brokerage commissions received by
affiliated brokers could be offset against the advisory fee paid by the Fund to
the Manager. After considering all factors deemed relevant, the Board of
Directors made a determination not to seek such recapture. The Board will
reconsider this matter from time to time.
 
                              SHAREHOLDER SERVICES
 
     The Fund offers a number of shareholder services and investment plans
described below that are designed to facilitate investment in shares of the
Fund. Certain of such services are not available to investors who place orders
for the Fund through the Merrill Lynch Blueprint(SM) Program. Full details as to
each of such services, copies of the various plans and instructions as to how to
participate in the various services or plans, or how to change options with
respect thereto, can be obtained from the Fund, by calling the telephone number
on the cover page hereof, or from the Distributor or Merrill Lynch.
 
INVESTMENT ACCOUNT
 
     Each shareholder whose account is maintained at the Transfer Agent has an
Investment Account and will receive statements, at least quarterly, from the
Transfer Agent. These statements will serve as transaction confirmations for
automatic investment purchases and the reinvestment of ordinary income dividends
and capital gain distributions. The statements will also show any other activity
in the account since the preceding statement. Shareholders will also receive
separate confirmations for each purchase or sale transaction other than
automatic investment purchases and the reinvestment of ordinary income dividends
and capital gains distributions. A shareholder with an account held at the
Transfer Agent may make additions to his or her Investment Account at any time
by mailing a check directly to the Transfer Agent. A shareholder may also
maintain an account through Merrill Lynch. Upon the transfer of shares out of a
Merrill Lynch brokerage account, an Investment Account in the transferring
shareholder's name may be opened automatically at the Transfer Agent.
 
                                       31
<PAGE>   66
 
     Share certificates are issued only for full shares and only upon the
specific request of a shareholder who has an Investment Account. Issuance of
certificates representing all or only part of the full shares in an Investment
Account may be requested by a shareholder directly from the Transfer Agent.
 
     Shareholders considering transferring their Class A or Class D shares from
Merrill Lynch to another brokerage firm or financial institution should be aware
that, if the firm to which the Class A or Class D shares are to be transferred
will not take delivery of shares of the Fund, a shareholder either must redeem
the Class A or Class D shares (paying any applicable CDSC) so that the cash
proceeds can be transferred to the account at the new firm or continue to
maintain an Investment Account at the Transfer Agent for those Class A or Class
D shares. Shareholders interested in transferring their Class B or Class C
shares from Merrill Lynch who do not wish to have an Investment Account
maintained for such shares at the Transfer Agent may request their new brokerage
firm to maintain such shares in an account registered in the name of the
brokerage firm for the benefit of the shareholder at the Transfer Agent. If the
new brokerage firm is willing to accommodate the shareholder in this manner, the
shareholder must request that he or she be issued certificates for his or her
shares and then must turn the certificates over to the new firm for
re-registration in the new brokerage firm's name.
 
EXCHANGE PRIVILEGE
 
     U.S. shareholders of each class of shares of the Fund have an exchange
privilege with certain other Select Pricing Funds and Summit Cash Reserves Fund
("Summit"), a series of Financial Institutions Series Trust, which is a Merrill
Lynch-sponsored money market fund specifically designated as available for
exchange by holders of Class A, Class B, Class C and Class D shares of Select
Pricing Funds. Shares with a net asset value of at least $100 are required to
qualify for the exchange privilege and any shares utilized in an exchange must
have been held by the shareholder for at least 15 days. Before effecting an
exchange, shareholders should obtain a currently effective prospectus of the
fund into which the exchange is to be made. Exercise of the exchange privilege
is treated as a sale of the exchanged shares and a purchase of the acquired
shares for Federal income tax purposes.
 
     Exchanges of Class A and Class D Shares.  Class A shareholders may exchange
Class A shares of the Fund for Class A shares of a second Select Pricing Fund if
the shareholder holds any Class A shares of the second fund in his or her
account in which the exchange is made at the time of the exchange or is
otherwise eligible to purchase Class A shares of the second fund. If the Class A
shareholder wants to exchange Class A shares for shares of a second Select
Pricing Fund, but does not hold Class A shares of the second fund in his or her
account at the time of the exchange and is not otherwise eligible to acquire
Class A shares of the second fund, the shareholder will receive Class D shares
of the second fund as a result of the exchange. Class D shares also may be
exchanged for Class A shares of a second Select Pricing Fund at any time as long
as, at the time of the exchange, the shareholder holds Class A shares of the
second fund in the account in which the exchange is made or is otherwise
eligible to purchase Class A shares of the second fund. Class D shares are
exchangeable with shares of the same class of other Select Pricing Funds.
 
     Exchanges of Class A or Class D shares outstanding ("outstanding Class A or
Class D shares") for Class A or Class D shares of other Select Pricing Funds or
for Class A shares of Summit ("new Class A or Class D shares"), are transacted
on the basis of relative net asset value per Class A or Class D share,
respectively, plus an amount equal to the difference, if any, between the sales
charge previously paid on the outstanding Class A or Class D shares and the
sales charge payable at the time of the exchange on the new Class A or Class D
shares. With respect to outstanding Class A or Class D shares as to which
previous exchanges have taken place, the "sales charge previously paid" shall
include the aggregate of the sales charges paid with respect to such Class A or
Class D shares in the initial purchase and any subsequent exchange. Class A or
Class D shares issued pursuant to dividend reinvestment are sold on a no-load
basis in each of the funds offering Class A or Class D shares. For purposes of
the exchange privilege, Class A or Class D shares acquired through dividend
reinvestment shall be deemed to have been sold with a sales charge equal to the
sales charge previously paid on the Class A or Class D shares on which the
dividend was paid. Based on this formula, Class A and Class D shares generally
may be exchanged into the Class A or Class D shares, respectively, of the other
funds with a reduced sales charge or without a sales charge.
 
                                       32
<PAGE>   67
 
     Exchanges of Class B and Class C Shares.  Each Select Pricing Fund with
Class B or Class C shares outstanding ("outstanding Class B or Class C shares")
offers to exchange its Class B or Class C shares for Class B or Class C shares,
respectively, of another Select Pricing Fund or for Class B shares of Summit
("new Class B or Class C shares") on the basis of relative net asset value per
Class B or Class C share, without the payment of any CDSC that might otherwise
be due on redemption of the outstanding shares. Class B shareholders of the Fund
exercising the exchange privilege will continue to be subject to the Fund's CDSC
schedule if such schedule is higher than the CDSC schedule relating to the new
Class B shares acquired through use of the exchange privilege. In addition,
Class B shares of the Fund acquired through use of the exchange privilege will
be subject to the Fund's CDSC schedule if such schedule is higher than the CDSC
schedule relating to the Class B or Class C shares of the fund from which the
exchange has been made. For purposes of computing the CDSC that may be payable
on a disposition of the new Class B or Class C shares, the holding period for
the outstanding Class B or Class C shares is "tacked" to the holding period of
the new Class B or Class C shares. For example, an investor may exchange Class B
or Class C shares of the Fund for those of Merrill Lynch Special Value Fund,
Inc. ("Special Value Fund") after having held the Fund's Class B shares for two
and a half years. The 2% CDSC that generally would apply to a redemption would
not apply to the exchange. Three years later the investor may decide to redeem
the Class B shares of Special Value Fund and receive cash. There will be no CDSC
due on this redemption, since by "tacking" the two and a half year holding
period of Fund Class B shares to the three-year holding period for the Special
Value Fund Class B shares, the investor will be deemed to have held the Special
Value Fund Class B shares for more than five years.
 
   
     Exchanges for Shares of a Money Market Fund.  Class A and Class D shares
are exchangeable for Class A shares of Summit and Class B and Class C shares are
exchangeable for Class B shares of Summit. Class A shares of Summit have an
exchange privilege back into Class A or Class D shares of Select Pricing Funds;
Class B shares of Summit have an exchange privilege back into Class B or Class C
shares of Select Pricing Funds and, in the event of such an exchange, the period
of time that Class B shares of Summit are held will count toward satisfaction of
the holding period requirement for purposes of reducing any CDSC and toward
satisfaction of any Conversion Period with respect to Class B shares. Class B
shares of Summit will be subject to a distribution fee at an annual rate of
0.75% of average daily net assets of such Class B shares. This exchange
privilege does not apply with respect to certain Merrill Lynch fee-based
programs, for which alternative exchange arrangements may exist. Please see your
Merrill Lynch Financial Consultant for further information.
    
 
     Prior to October 12, 1998, exchanges from the Fund and other Select Pricing
Funds into a money market fund were directed to certain Merrill Lynch-sponsored
money market funds other than Summit. Shareholders who have exchanged Select
Pricing Fund shares for shares of such other market funds and subsequently wish
to exchange those money market fund shares for shares of the Fund will be
subject to the CDSC schedule applicable to such Fund shares, if any. The holding
period for those money market fund shares will not count toward satisfaction of
the holding period requirement for reduction of the CDSC imposed on such shares,
if any, and, with respect to Class B shares, toward satisfaction of the
Conversion Period. However, the holding period for Class B or Class C shares
received in exchange for such money market fund shares will be aggregated with
the holding period for the original Select Pricing Fund shares for purposes of
reducing the CDSC or satisfying the Conversion Period.
 
   
     Exchanges by Participants in the MFA Program.  The exchange privilege is
modified with respect to certain retirement plans which participate in the MFA
Program. Such retirement plans may exchange Class B, Class C or Class D shares
that have been held for at least one year for Class A shares of the same fund on
the basis of relative net asset values in connection with the commencement of
participation in the MFA Program, i.e., no CDSC will apply. The one year holding
period does not apply to shares acquired through reinvestment of dividends. Upon
termination of participation in the MFA Program, Class A shares will be
re-exchanged for the class of shares originally held. For purposes of computing
any CDSC that may be payable upon redemption of Class B or Class C shares so
reacquired, or the Conversion Period for Class B shares so reacquired, the
holding period for the Class A shares will be "tacked" to the holding period for
the Class B or Class C shares originally held. The Fund's exchange privilege is
also modified with respect to
    
 
                                       33
<PAGE>   68
 
   
purchases of Class A and Class D shares by non-retirement plan investors under
the MFA Program. First, the initial allocation of assets is made under the MFA
Program. Then, any subsequent exchange under the MFA Program of Class A or Class
D shares of a Select Pricing Fund for Class A or Class D shares of the Fund will
be made solely on the basis of the relative net asset values of the shares being
exchanged. Therefore, there will not be a charge for any difference between the
sales charge previously paid on the shares of the other Select Pricing Fund and
the sales charge payable on the shares of the Fund being acquired in the
exchange under the MFA Program.
    
 
     Exercise of the Exchange Privilege.  To exercise the exchange privilege, a
shareholder should contact his or her Merrill Lynch Financial Consultant, who
will advise the Fund of the exchange. Shareholders of the Fund, and shareholders
of the other Select Pricing Funds with shares for which certificates have not
been issued, may exercise the exchange privilege by wire through their
securities dealers. The Fund reserves the right to require a properly completed
Exchange Application. This exchange privilege may be modified or terminated in
accordance with the rules of the Commission. The Fund reserves the right to
limit the number of times an investor may exercise the exchange privilege.
Certain funds may suspend the continuous offering of their shares to the general
public at any time and may thereafter resume such offering from time to time.
The exchange privilege is available only to U.S. shareholders in states where
the exchange legally may be made. It is contemplated that the exchange privilege
may be applicable to other new mutual funds whose shares may be distributed by
the Distributor.
 
FEE-BASED PROGRAMS
 
     Certain Merrill Lynch fee-based programs, including pricing alternatives
for securities transactions (each referred to in this paragraph as a "Program"),
may permit the purchase of Class A shares at net asset value. Under specified
circumstances, participants in certain Programs may deposit other classes of
shares which will be exchanged for Class A shares. Initial or deferred sales
charges otherwise due in connection with such exchanges may be waived or
modified, as may the Conversion Period applicable to the deposited shares.
Termination of participation in a Program may result in the redemption of shares
held therein or the automatic exchange thereof to another class at net asset
value, which may be shares of a money market fund. In addition, upon termination
of participation in a Program, shares that have been held for less than
specified periods within such Program may be subject to a fee based upon the
current value of such shares. These Programs also generally prohibit such shares
from being transferred to another account at Merrill Lynch, to another
broker-dealer or to the Transfer Agent. Except in limited circumstances (which
may also involve an exchange as described above), such shares must be redeemed
and another class of shares purchased (which may involve the imposition of
initial or deferred sales charges and distribution and account maintenance fees)
in order for the investment not to be subject to Program fees. Additional
information regarding a specific Program (including charges and limitations on
transferability applicable to shares that may be held in such Program) is
available in such Program's client agreement and from the Transfer Agent at
1-800-MER-FUND or 1-800-637-3863.
 
AUTOMATIC INVESTMENT PLANS
 
     A shareholder may make additions to an Investment Account at any time by
purchasing Class A shares (if he or she is an eligible Class A investor) or
Class B, Class C or Class D shares at the applicable public offering price.
These purchases may be made either through the shareholder's securities dealer,
or by mail directly to the Transfer Agent, acting as agent for such securities
dealer. Voluntary accumulation also can be made through a service known as the
Fund's Automatic Investment Plan. The Fund would be authorized, on a regular
basis, to provide systematic additions to the Investment Account of such
shareholder through charges of $50 or more to the regular bank account of the
shareholder by either pre-authorized checks or automated clearing house debits.
An investor whose shares of the Fund are held within a CMA(R) or CBA(R) account
may arrange to have periodic investments made in the Fund in amounts of $100 ($1
for retirement accounts) or more through the CMA(R) or CBA(R) Automated
Investment Program.
 
                                       34
<PAGE>   69
 
AUTOMATIC DIVIDEND PROGRAM
 
     Unless specific instructions are given as to the method of payment,
dividends and capital gains distributions will be automatically reinvested,
without sales charge, in additional full and fractional shares of the Fund. Such
reinvestment will be at the net asset value of shares of the Fund as of the
close of business on the NYSE on the monthly payment date for such dividends and
distributions. No CDSC will be imposed upon redemption of shares issued as a
result of the automatic reinvestment of dividends or capital gains
distributions.
 
     Shareholders may, at any time, by written notification to Merrill Lynch if
their account is maintained with Merrill Lynch, or by written notification or by
telephone (1-800-MER-FUND) to the Transfer Agent, if their account is maintained
with the Transfer Agent elect to have subsequent dividends or both dividends and
capital gains distributions, paid in cash, rather than reinvested in shares of
the Fund or vice versa (provided that, in the event that a payment on an account
maintained at the Transfer Agent would amount to $10.00 or less, a shareholder
will not receive such payment in cash and such payment will automatically be
reinvested in additional shares). Commencing ten days after the receipt by the
Transfer Agent of such notice, those instructions will be effected. The Fund is
not responsible for any failure of delivery to the shareholder's address of
record and no interest will accrue on amounts represented by uncashed
distribution checks. Cash payments can also be directly deposited to the
shareholder's bank account.
 
   
SYSTEMATIC WITHDRAWAL PLAN
    
 
     A shareholder may elect to receive systematic withdrawals from his or her
Investment Account by check or through automatic payment by direct deposit to
his or her bank account on either a monthly or quarterly basis as provided
below. Quarterly withdrawals are available for shareholders that have acquired
shares of the Fund having a value, based on cost or the current offering price,
of $5,000 or more, and monthly withdrawals are available for shareholders with
shares having a value of $10,000 or more.
 
     At the time of each withdrawal payment, sufficient Class A, Class B, Class
C or Class D shares are redeemed from those on deposit in the shareholder's
account to provide the withdrawal payment specified by the shareholder. The
shareholder may specify the dollar amount and the class of shares to be
redeemed. Redemptions will be made at net asset value as 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 24th day of each month or the 24th day of the
last month of each quarter, whichever is applicable. If the NYSE is not open for
business on such date, the shares will be redeemed at the net asset value
determined 15 minutes after the close of business on the NYSE on the following
business day. The check for the withdrawal payment will be mailed, or the direct
deposit of the withdrawal payment will be made, on the next business day
following redemption. When a shareholder is making systematic withdrawals,
dividends and distributions on all shares in the Investment Account are
reinvested automatically in Fund shares. A shareholder's Systematic Withdrawal
Plan may be terminated at any time, without charge or penalty, by the
shareholder, the Fund, the Transfer Agent or the Distributor.
 
   
     With respect to redemptions of Class B or Class C shares pursuant to a
systematic withdrawal plan, the maximum number of Class B or Class C shares that
can be redeemed from an account annually shall not exceed 10% of the value of
shares of such class in that account at the time the election to join the
systematic withdrawal plan was made. Any CDSC that otherwise might be due on
such redemption of Class B or Class C shares will be waived. Shares redeemed
pursuant to a systematic withdrawal plan will be redeemed in the same order as
Class B or Class C shares are otherwise redeemed. See "Purchase of
Shares -- Deferred Sales Charge Alternatives -- Class B and Class C Shares."
Where the systematic withdrawal plan is applied to Class B shares, upon
conversion of the last Class B shares in an account to Class D shares, the
systematic withdrawal plan will be applied thereafter to Class D shares if the
shareholder so elects. If an investor wishes to change the amount being
withdrawn in a systematic withdrawal plan the investor should contact his or her
Financial Consultant.

     Withdrawal payments should not be considered as dividends. Each withdrawal
is a taxable event. If periodic withdrawals continuously exceed reinvested
dividends, the shareholder's original investment may be reduced correspondingly.
Purchases of additional shares concurrent with withdrawals are ordinarily
disadvantageous to the shareholder because of sales charges and tax liabilities.
The Fund will not knowingly accept purchase orders for shares of the Fund from
investors that maintain a Systematic Withdrawal Plan unless such purchase is
equal to at least one year's scheduled withdrawals or $1,200, whichever is
greater. Automatic investments may not be made into an Investment Account in
which the shareholder has elected to make systematic withdrawals.
 
     Alternatively, a shareholder whose shares are held within a CMA(R) or
CBA(R) Account may elect to have shares redeemed on a monthly, bimonthly,
quarterly, semiannual or annual basis through the CMA(R) or CBA(R) Systematic
Redemption Program. The minimum fixed dollar amount redeemable is $50. The
proceeds of systematic redemptions will be posted to the shareholder's account
three business days after the date the shares are redeemed. All redemptions are
made at net asset value. A shareholder may elect to have his or her shares
redeemed on the first, second, third or fourth Monday of each month, in the case
of monthly redemptions, or of every other month, in the case of bimonthly
redemptions. For quarterly, semiannual or annual redemptions, the shareholder
may select the month in which the shares are to be redeemed and may designate
whether the redemption is to be made on the first, second, third or fourth
Monday of the month. If the Monday selected is not a business day, the
redemption will be processed at net asset value on the next business day. The
CMA(R) or CBA(R) Systematic Redemption Program is not available if Fund shares
are being purchased within the account pursuant to the Automated Investment
Program. For more information on the CMA(R) or CBA(R) Systematic Redemption
Program, eligible shareholders should contact their Merrill Lynch Financial
Consultant.
 
                            DISTRIBUTIONS AND TAXES
 
DIVIDENDS AND DISTRIBUTIONS
 
     It is the Fund's intention to distribute substantially all of its net
investment income, if any. Dividends from such net investment income will be
paid at least annually. All net realized capital gains, if any, will be
distributed as dividends to the Fund's shareholders at least annually. The per
share dividends on each class of shares will be reduced as a result of any
account maintenance, distribution and transfer agency fees applicable to that
class. See "Pricing of Shares -- Determination of Net Asset Value." Dividends
will be reinvested automatically in shares of the Fund at net asset value
without a sales charge. However, a shareholder whose account is maintained at
the Transfer Agent or whose account is maintained through Merrill Lynch may
elect in writing to receive any such dividends or distributions or both in cash.
Dividends and distributions are taxable to shareholders as discussed above
whether they are reinvested in shares of the Fund or received in cash. From time
to time, the Fund may declare a special distribution at or about the end of the
calendar year in order to comply with Federal tax requirements that certain
percentages of its ordinary income and capital gains be distributed during the
calendar year.
 
     Gains or losses attributable to certain foreign currency transactions may
increase or decrease the amount of the Fund's income available for distribution
to shareholders. If such losses exceed other ordinary income during a taxable
year, (a) the Fund would not be able to make any ordinary income dividend
distributions and (b) all or a portion of distributions made before the losses
were realized but in the same taxable year would be recharacterized as returns
of capital to shareholders, rather than as ordinary income dividends, thereby
reducing each shareholder's tax basis in his or her Fund shares for Federal
income tax purposes and resulting in a capital gain for any shareholder who
received a distribution greater than the shareholder's tax basis in Fund shares
(assuming that the shares were held as a capital asset). For a detailed
discussion of the Federal tax considerations relevant to foreign currency
transactions, see "Taxes."
 
     The per share dividends and distributions on each class of shares will be
reduced as a result of any account maintenance, distribution and transfer agency
fees applicable to that class. See "Pricing of Shares -- Determination of Net
Asset Value."
 
                                       36
<PAGE>   71
 
     See "Shareholder Services" for information as to how to elect either
dividend reinvestment or cash payments. Dividends and distributions are taxable
to shareholders whether they are reinvested in shares of the Fund or received in
cash.
 
TAXES
 
     The Fund intends to continue to qualify for the special tax treatment
afforded regulated investment companies ("RICs") under the Code. As long as it
so qualifies, the Fund (but not its shareholders) will not be subject to Federal
income tax on the part of its net ordinary income and net realized capital gains
that it distributes to Class A, Class B, Class C and Class D shareholders
(together, the "shareholders"). The Fund intends to distribute substantially all
of such income.
 
   
     Dividends paid by the Fund from its ordinary income or from an excess of
net short-term capital gains over net long-term capital losses (together
referred to hereafter as "ordinary income dividends") are taxable to
shareholders as ordinary income. Distributions made from an excess of net
long-term capital gains over net short-term capital losses (including gains or
losses from certain transactions in warrants, futures and options) ("capital
gain dividends") are taxable to shareholders as long-term capital gains,
regardless of the length of time the shareholder has owned Fund shares. Certain
categories of capital gains are taxable at different rates. Any loss upon the
sale or exchange of Fund shares held for six months or less will be treated as
long-term capital loss to the extent of any capital gain dividends received by
the shareholder. 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). 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 ordinary
income dividends or capital gain dividends, as well as any amounts of capital
gain dividends in the different categories of capital gain referred to above.
    
 
     Dividends are taxable to shareholders even though they are reinvested in
additional shares of the Fund. A portion of the Fund's ordinary income dividends
may be eligible for the dividends received deduction allowed to corporations
under the Code, if certain requirements are met. For this purpose, the Fund will
allocate dividends eligible for the dividends received deduction among the Class
A, Class B, Class C and Class D shareholders according to a method (which it
believes is consistent with the Commission rule permitting the issuance and sale
of multiple classes of stock) that is based on the gross income allocable to
Class A, Class B, Class C and Class D shareholders during the taxable year, or
such other method as the Internal Revenue Service may prescribe. 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.
 
     Dividends and interest received by the Fund may give rise to withholding
and other taxes imposed by foreign countries. Tax conventions between certain
countries and the United States may reduce or eliminate such taxes. Shareholders
may be able to claim United States foreign tax credits with respect to such
taxes, subject to certain conditions and limitations contained in the Code. For
example, certain retirement accounts cannot claim foreign tax credits on
investments in foreign securities held in the Fund. In addition, recent
legislation permits a foreign tax credit to be claimed with respect to
withholding tax on a dividend only if the shareholder meets certain holding
period requirements. The Fund also must meet these holding period requirements,
and if the Fund fails to do so, it will not be able to "pass through" to
shareholders the ability to claim a credit or a deduction for the related
foreign taxes paid by the Fund. If the Fund satisfies the holding period
requirements and if more than 50% in value of the Fund's total assets at the
close of its taxable year consists of securities of foreign corporations, the
Fund will be eligible, and intends, to file an election with the Internal
Revenue Service pursuant to which shareholders of the Fund will be required to
include their proportionate shares of such withholding taxes in their United
States income tax returns as gross income, treat such proportionate shares as
taxes paid by them, and deduct such proportionate shares in computing their
taxable incomes or, alternatively, use them as foreign tax credits against their
United States income taxes. No deductions for foreign taxes, moreover, may be
claimed by noncorporate shareholders who do not itemize
 
                                       37
<PAGE>   72
 
deductions. A shareholder that is a nonresident alien individual or a foreign
corporation may be subject to U.S. withholding tax on the income resulting from
the Fund's election described in this paragraph but may not be able to claim a
credit or deduction against such U.S. tax for the foreign taxes treated as
having been paid by such shareholder. The Fund will report annually to its
shareholders the amount per share of such withholding taxes and other
information needed to claim the foreign tax credit. For this purpose, the Fund
will allocate foreign taxes and foreign source income among the Class A, Class
B, Class C and Class D shareholders according to a method similar to that
described above for the allocation of dividends eligible for the dividends
received deduction.
 
     No gain or loss will be recognized by Class B shareholders on the
conversion of their Class B shares into Class D shares. A shareholder's basis in
the Class D shares acquired will be the same as such shareholder's basis in the
Class B shares converted and the holding period of the acquired Class D shares
will include the holding period for the converted Class B shares.
 
     If a shareholder exercises an exchange privilege within 90 days of
acquiring the shares, then the loss the shareholder can recognize on the
exchange will be reduced (or the gain increased) to the extent any sales charge
paid to the Fund reduces any sales charge the shareholder would have owed upon
purchase of the new shares in the absence of the exchange privilege. Instead,
such sales charge will be treated as an amount paid for the new shares.
 
     A loss realized on a sale or exchange of shares of the Fund will be
disallowed if other Fund shares are acquired (whether through the automatic
reinvestment of dividends or otherwise) within a 61-day period beginning 30 days
before and ending 30 days after the date that the shares are disposed of. In
such a case, the basis of the shares acquired will be adjusted to reflect the
disallowed loss.
 
     Ordinary income dividends paid to shareholders that 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 advisors concerning the applicability of the United States withholding
tax.
 
     Under certain provisions of the Code, some shareholders may be subject to a
31% withholding tax on ordinary income dividends, capital gain dividends and
redemption payments ("backup withholding"). Generally, shareholders subject to
backup withholding will be 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 shareholder
is not otherwise subject to backup withholding.
 
     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. While the Fund intends to distribute its income and
capital gains in the manner necessary to minimize imposition of the 4% excise
tax, there can be no assurance that sufficient amounts of the Fund's taxable
income and capital gains will be distributed to avoid entirely the imposition of
the tax. In such event, the Fund will be liable for the tax only on the amount
by which it does not meet the foregoing distribution requirements.
 
     The Fund may invest in securities rated in the medium to lower rating
categories of nationally recognized rating organizations, and in unrated
securities ("high yield/high risk securities"). Some of these high yield/high
risk securities may be purchased at a discount and may therefore cause the Fund
to accrue and distribute income before amounts due under the obligations are
paid. In addition, a portion of the interest payments on such high yield/high
risk securities may be treated as dividends for Federal income tax purposes; in
such case, if the issuer of such high yield/high risk securities is a domestic
corporation, dividend payments by the Fund will be eligible for the dividends
received deduction to the extent of the deemed dividend portion of such interest
payments.
 
                                       38
<PAGE>   73
 
     The Fund may invest up to 10% of its total assets in securities of other
investment companies. If the Fund purchases shares of an investment company (or
similar investment entity) organized under foreign law, the Fund will be treated
as owning shares in a passive foreign investment company ("PFIC") for U.S.
Federal income tax purposes. The Fund may be subject to U.S. Federal income tax,
and an additional tax in the nature of interest (the "interest charge"), on a
portion of the distributions from such a company and on gain from the
disposition of the shares of such a company (collectively referred to as "excess
distributions"), even if such excess distributions are paid by the Fund as a
dividend to its shareholders. The Fund may be eligible to make an election with
respect to certain PFICs in which it owns shares that will allow it to avoid the
taxes on excess distributions. However, such election may cause the Fund to
recognize income in a particular year in excess of the distributions received
from such PFICs. Alternatively, under recent legislation the Fund would be able
to elect to "mark to market" at the end of each taxable year all shares that it
holds in PFICs. If it made this election, the Fund would recognize as ordinary
income any increase in the value of such shares over their adjusted basis and as
ordinary loss any decrease in such value to the extent it did not exceed prior
increases. By making the mark-to-market election, the Fund could avoid
imposition of the interest charge with respect to its distributions from PFICs,
but in any particular year might be required to recognize income in excess of
the distributions it received from PFICs and its proceeds from dispositions of
PFIC stock.
 
TAX TREATMENT OF OPTIONS, FUTURES AND FORWARD FOREIGN EXCHANGE TRANSACTIONS
 
     The Fund may write, purchase or sell options and futures contracts and
engage in forward foreign exchange transactions. Options and futures contracts
that are "Section 1256 contracts" will be "marked to market" for Federal income
tax purposes at the end of each taxable year, i.e., each such option or futures
contract will be treated as sold for its fair market value on the last day of
the taxable year. Unless such contract is a forward foreign exchange contract,
or is a non-equity option or a regulated futures contract for a non-U.S.
currency for which the Fund elects to have gain or loss treated as ordinary gain
or loss under Code Section 988 (as described below), gain or loss from 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 or
currency exchange rates with respect to its investments.
 
     A forward foreign exchange contract that is a Section 1256 contract will be
marked to market, as described above. However, the character of gain or loss
from such a contract will generally be ordinary under Code Section 988. The Fund
may, nonetheless, elect to treat the gain or loss from certain forward foreign
exchange contracts as capital. In this case, gain or loss realized in connection
with a forward foreign exchange contract that is a Section 1256 contract will be
characterized as 60% long-term and 40% short-term capital gain or loss.
 
     Code Section 1092, which applies to certain "straddles," may affect the
taxation of the Fund's sales of securities and transactions in options, futures
and forward foreign exchange contracts. 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 options, futures and
forward foreign exchange contracts.
 
SPECIAL RULES FOR CERTAIN FOREIGN CURRENCY TRANSACTIONS
 
     In general, gains from "foreign currencies" and from foreign currency
options, foreign currency futures and forward foreign exchange contracts
relating to investments in stocks, securities or foreign currencies will be
qualifying income for purposes of determining whether the Fund qualifies as a
RIC. It is currently unclear, however, who will be treated as the issuer of a
foreign currency instrument or how foreign currency options, futures, or forward
foreign exchange contracts will be valued for purposes of the RIC
diversification requirements applicable to the Fund.
 
                                       39
<PAGE>   74
 
     Under Code Section 988, special rules are provided for certain transactions
in a foreign currency other than the taxpayer's functional currency (i.e.,
unless certain special rules apply, currencies other than the U.S. dollar). In
general, foreign currency gains or losses from certain debt instruments, from
certain forward contracts, from futures contracts that are not "regulated
futures contracts" and from unlisted options will be treated as ordinary income
or loss under Code Section 988. In certain circumstances, the Fund may elect
capital gain or loss treatment for such transactions. Regulated futures
contracts, as described above, will be taxed under Code Section 1256 unless
application of Section 988 is elected by the Fund. In general, however, Code
Section 988 gains or losses will increase or decrease the amount of the Fund's
investment company taxable income available to be distributed to shareholders as
ordinary income. Additionally, if Code Section 988 losses exceed other
investment company taxable income during a taxable year, the Fund would not be
able to make any ordinary income dividend distributions, and all or a portion of
distributions made before the losses were realized but in the same taxable year
would be recharacterized as a return of capital to shareholders, thereby
reducing the basis of each shareholder's Fund shares and resulting in a capital
gain for any shareholder who received a distribution greater than such
shareholder's basis in Fund shares (assuming the shares were held as a capital
asset). These rules and the mark-to-market rules described above, however, will
not apply to certain transactions entered into by the Fund solely to reduce the
risk of currency fluctuations with respect to its investments.
 
     The foregoing is a general and abbreviated summary of the applicable
provisions of the Code and Treasury regulations presently in effect. For the
complete provisions, reference should be made to the pertinent Code sections and
the Treasury regulations promulgated thereunder. The Code and the Treasury
regulations are subject to change by legislative, judicial or administrative
action either prospectively or retroactively.
 
     Ordinary income and capital gain dividends may also be subject to state and
local taxes.
 
     Certain states exempt from state income taxation dividends paid by RICs
which are derived from interest on U.S. Government obligations. State law varies
as to whether dividend income attributable to U.S. Government obligations is
exempt from state income tax.
 
     Shareholders are urged to consult their own tax advisers regarding specific
questions as to Federal, foreign, state or local taxes. Foreign investors should
consider applicable foreign taxes in their evaluation of an investment in the
Fund.
 
                                PERFORMANCE DATA
 
     From time to time the Fund may include its average annual total return and
other total return data in advertisements or information furnished to present or
prospective shareholders. Total return figures are based on the Fund's
historical performance and are not intended to indicate future performance.
Average annual total return is determined separately for Class A, Class B, Class
C and Class D shares in accordance with formulas specified by the Commission.
 
     Average annual total return quotations for the specified periods are
computed by finding the average annual compounded rates of return (based on net
investment income and any realized and unrealized capital gains or losses on
portfolio investments over such periods) that would equate the initial amount
invested to the redeemable value of such investment at the end of each period.
Average annual total return is computed assuming all dividends and distributions
are reinvested and taking into account all applicable recurring and nonrecurring
expenses, including the maximum sales charge in the case of Class A and Class D
shares and the CDSC that would be applicable to a complete redemption of the
investment at the end of the specified period in the case of Class B and Class C
shares. Dividends paid by the Fund with respect to all shares, to the extent any
dividends are paid, will be calculated in the same manner at the same time on
the same day and will be in the same amount, except that account maintenance and
distribution charges and any incremental transfer agency costs relating to each
class of shares will be borne exclusively by that class. The Fund will include
performance data for all classes of shares of the Fund in any advertisement or
information including performance data of the Fund.
 
                                       40
<PAGE>   75
 
     The Fund also may quote annual, average annual and annualized total return
and aggregate total return performance data, both as a percentage and as a
dollar amount based on a hypothetical $1,000 investment, for various periods
other than those noted below. Such data will be computed as described above,
except that (1) as required by the periods of the quotations, actual annual,
annualized or aggregate data, rather than average annual data, may be quoted and
(2) the maximum applicable sales charges will not be included with respect to
annual or annualized rates of return calculations. Aside from the impact on the
performance data calculations of including or excluding the maximum applicable
sales charges, actual annual or annualized total return data generally will be
lower than average annual total return data since the average rates of return
reflect compounding of return; aggregate total return data generally will be
higher than average annual total return data since the aggregate rates of return
reflect compounding over a longer period of time.
 
   
     On occasion, the Fund may compare its performance to that of the Value Line
Convertible Index, The Financial Times/Standard & Poor's Actuarial World
Indices, the Morgan Stanley Capital International Indices, the Dow Jones
Industrial Average or performance data published by Lipper Analytical Services,
Inc., Morningstar Publications, Inc. ("Morningstar"), CDA Investment Technology
Inc., Money Magazine, U.S. News & World Report, Business Week, Forbes Magazine,
Fortune Magazine or other industry publications. When comparing its performance
to a market index, the Fund may refer to various statistical measures derived
from the historic performance of the Fund and the index, such as standard
deviation and beta. In addition, from time to time, the Fund may include the
Fund's Morningstar risk-adjusted performance ratings in advertisements or
supplemental sales literature. As with other performance data, performance
comparisons should not be considered indicative of the Fund's relative
performance for any future period.

* Prior to August 4, 1997, the Fund operated as a dual-structure closed-end
  investment company. On August 4, 1997, the Fund converted to an open-end
  investment company and Capital Shares outstanding as of that date were
  designated Class A shares.

     In order to reflect the reduced sales charges in the case of Class A or
Class D shares, or the waiver of the CDSC in the case of Class B or Class C
shares applicable to certain investors, as described under "Purchase of Shares"
the total return data quoted by the Fund in advertisements directed to such
investors may take into account the reduced, and not the maximum, sales charge
or may not take into account the CDSC, and, therefore, may reflect greater total
return since, due to the reduced sales charges or the waiver of CDSCs, a lower
amount of expenses may be deducted.
 
   
     The Fund's total return will vary depending on market conditions, the
securities comprising the Fund's portfolio, the Fund's operating expenses and
the amount of realized and unrealized net capital gains or losses during the
period. The value of an investment in the Fund will fluctuate and an investor's
shares, when redeemed, may be worth more or less than their original cost.
    
 
                              GENERAL INFORMATION
 
DESCRIPTION OF SHARES
 
     The Fund was incorporated under Maryland law on May 24, 1985 as
"Convertible Holdings, Inc." a closed-end investment company. On February 13,
1997, the shareholders of the Fund voted to convert the Fund to an open-end
investment company. Amended and Restated Articles of Incorporation, effective as
of August 4, 1997, (i) converted the Fund to an open-end investment company,
(ii) renamed the Fund "Merrill Lynch Convertible Fund, Inc." and (iii) increased
the authorized capital stock from 30,000,000 shares, par value $.10 per share,
to 400,000,000 shares of Common Stock, par value $.10 per share. The shares of
Common Stock are divided into four classes designated Class A, Class B, Class C
and Class D Common Stock, each consisting of 100,000,000 shares. Shares of Class
A, Class B, Class C and Class D Common Stock represent an interest in the same
assets of the Fund and are identical in all respects except that the Class B,
Class C and Class D shares bear certain expenses related to the account
maintenance and/or distribution of such shares and have exclusive voting rights
with respect to matters relating to such expenditures. At the time of conversion
of the Fund into an open-end investment company, the Fund had approximately
11,653,700 Capital Shares outstanding, all of which were reclassified into
shares of Class A Common Stock upon such conversion. The Board of Directors of
the Fund may classify and reclassify the unissued shares of the Fund into
additional or other classes of Common Stock at a future date.
 
     Shareholders are entitled to one vote for each full share held and
fractional votes for fractional shares held in the election of Directors and any
other matter submitted to a shareholder vote. The Fund does not intend to hold
annual meetings of shareholders in any year in which the Investment Company Act
does not require shareholders to act upon any of the following matters: (i)
election of Directors; (ii) approval of an investment advisory agreement; (iii)
approval of a distribution agreement; and (iv) ratification of selection of
independent accountants. Also, the by-laws of the Fund require that a special
meeting of shareholders be held upon the written request of at least 25% of the
outstanding shares of the Fund entitled to vote at such meeting, if they comply
with applicable Maryland law. Voting rights for Directors are not cumulative.
Shares issued are fully paid and non-assessable and have no preemptive rights.
Redemption and conversion rights are discussed elsewhere herein and in the
Prospectus. Each share of Class B, Class C and Class D Common Stock is entitled
to participate equally in dividends and distributions declared by the Fund and
in the net assets of the Fund upon liquidation or dissolution after satisfaction
of outstanding liabilities. Stock certificates will be issued by the Transfer
Agent only on specific request. Certificates for fractional shares are not
issued in any case. Shareholders may, in accordance with Maryland law, cause a
meeting of shareholders to be held for the purpose of voting on the removal of
Directors at the request of 25% of the outstanding shares of the Fund. A
Director may be removed at a special meeting of shareholders by a vote of a
majority of the votes entitled to be cast for the election of Directors.

                                   APPENDIX I
 
               INVESTMENT PRACTICES INVOLVING THE USE OF OPTIONS,
                          FUTURES AND FOREIGN EXCHANGE
 
DERIVATIVES
 
     The Fund may use instruments referred to as "Derivatives." Derivatives are
financial instruments the value of which is derived from another security, a
commodity (such as gold or oil) or an index (a measure of value or rates, such
as the S&P 500 or the prime lending rate). Derivatives allow the Fund to
increase or decrease the level of risk to which the Fund is exposed more quickly
and efficiently than transactions in other types of instruments. Derivatives,
however, are volatile and involve significant risks, including
 
     Credit risk -- the risk that the counterparty on a Derivative transaction
will be unable to honor its financial obligation to the Fund.
 
     Currency risk -- the risk that changes in the exchange rate between two
currencies will adversely affect the value (in U.S. dollar terms) of an
investment.
 
     Leverage risk -- the risk associated with certain types of investments or
trading strategies (such as borrowing money to increase the amount of
investments) that relatively small market movements may result in large changes
in the value of an investment. Certain investments or trading strategies that
involve leverage can result in losses that greatly exceed the amount originally
invested.
 
     Liquidity risk -- the risk that certain securities may be difficult or
impossible to sell at the time that the seller would like or at the price that
the seller believes the security is currently worth.
 
     The Fund may use the following types of derivative instruments:
 
     Futures -- exchange-traded contracts involving the obligation of the seller
to deliver, and the buyer to receive, certain assets (or a money payment based
on the change in value of certain assets or an index) at a specified time.
Futures involve leverage risk and may involve currency risk.
 
     Forwards -- private contracts involving the obligation of the seller to
deliver, and the buyer to receive, certain assets (or a money payment based on
the change in value of certain assets or an index) at a specified time. Forwards
involve credit risk and leverage risk, and may involve currency risk.
 
     Options -- exchange-traded or private contracts involving the right of a
holder to deliver (a "put") or receive (a "call") certain assets (or a money
payment based on the change of certain assets or an index) from another party at
a specified price within a specified time period. Options involve leverage risk.
Private options also involve credit risk and liquidity risk. Options may involve
currency risk.
 
     Indexed Securities -- debt instruments for which the rate of interest paid
or the amount of principal to be returned upon maturity is based on an index.
Indexed securities involve credit risk, and frequently involve leverage risk,
liquidity risk and currency risk.
 
     Inverse Securities -- indexed securities the value of which will move in
the opposite direction of changes to an index. Inverse securities involve credit
risk, leverage risk and liquidity risk, and may involve currency risk.
 
   
     The Fund may use Derivatives for hedging purposes or speculative purposes.
    
 
     Hedging is a strategy in which a Derivative is used to offset the risk that
other Fund holdings may decrease in value. Losses on the other investment may be
substantially reduced by gains on a Derivative that reacts in an opposite manner
to market movements. While hedging can reduce losses, it can also reduce or
eliminate gains if the market moves in a different manner than anticipated by
the Fund or if the cost of the Derivative outweighs the benefit of the hedge.
Hedging also involves the risk that changes in the value of the Derivative will
not match those of the holdings being hedged as expected by the Fund, in which
case any losses on the holdings being hedged may not be reduced. This risk is
known as "Correlation Risk."
 
                                       I-1
<PAGE>   81
 
     The use of a Derivative is speculative if the Fund is primarily seeking to
achieve gains, rather than offset the risk of other positions. When the Fund
invests in a Derivative for speculative purposes, the Fund will be fully exposed
to the risks of loss of that Derivative, which may sometimes be greater than the
Derivative's cost. The Fund will not invest in a Derivative to gain exposure to
an asset or class of assets that it would be prohibited by its investment
restrictions from purchasing directly.
 
     The Fund may use the following types of Derivative instruments and trading
strategies:
 
INDEXED AND INVERSE SECURITIES
 
     The Fund may invest in securities the potential return of which is based on
an index. As an illustration, the Fund may invest in a debt security that pays
interest based on the current value of an interest rate index, such as the prime
rate. The Fund may also invest in a debt security which returns principal at
maturity based on the level of a securities index or a basket of securities, or
based on the relative changes of two indices. In addition, the Fund may invest
in securities the potential return of which is based inversely on the change in
an index (that is, a security the value of which will move in the opposite
direction of changes to an index). For example, the Fund may invest in
securities that pay a higher rate of interest when a particular index decreases
and pay a lower rate of interest (or do not fully return principal) when the
value of the index increases. If the Fund invests in such securities, it may be
subject to reduced or eliminated interest payments or loss of principal in the
event of an adverse movement in the relevant index or indices. Indexed and
inverse securities involve credit risk, and certain indexed and inverse
securities may involve leverage risk, liquidity risk and currency risk. The Fund
may invest in indexed and inverse securities for both hedging and speculative
purposes. When used for hedging purposes, indexed and inverse securities involve
correlation risk.
 
OPTIONS ON SECURITIES AND SECURITIES INDICES
 
     Purchasing Options.  The Fund may purchase put options on securities held
in its portfolio or securities or interest rate indices the performance of which
is substantially correlated with securities held in its portfolio. When the Fund
purchases a put option, in consideration for an upfront payment (the "option
premium"), the Fund acquires a right to sell to another party specified
securities owned by the Fund at a specified price (the "exercise price") on or
before a specified date (the "expiration date"), in the case of an option on
securities, or to receive from another party a payment based on the amount a
specified securities index declines below a specified level on or before the
expiration date, in the case of an option on a securities index. The purchase of
a put option limits the Fund's risk of loss in the event of a decline in the
market value of the portfolio holdings underlying the put option prior to the
option's expiration date. In the event the market value of the portfolio
holdings underlying the put option increases rather than decreases, however, the
Fund will lose the option premium and will consequently realize a lower return
on the portfolio holdings than would have been realized without the purchase of
the put. Purchasing a put option involves correlation risk, and may involve
liquidity and credit risk.
 
     The Fund may also purchase call options on securities or securities or
interest rate indices. When the Fund purchases a call option, in consideration
for the option premium the Fund acquires a right to purchase from another party
specified securities at the exercise price on or before the expiration date, in
the case of an option on securities, or to receive from another party a payment
based on the amount a specified securities index increases beyond a specified
level on or before the expiration date, in the case of an option on a securities
index. The purchase of a call option provides the Fund with the opportunity to
profit if the underlying security or security or interest rate index increases
in value. If the underlying security or security or interest rate index
decreases in value, however, the Fund may lose the entire option premium.
Purchasing a call option may involve correlation, liquidity and credit risk.
 
     The Fund may also purchase call options in connection with the creation of
Manufactured Convertibles and is also authorized to purchase put or call options
in connection with closing out put or call options it has previously sold.
 
     Writing Options.  The Fund may write (i.e., sell) call options on
securities held in its portfolio or securities indices the performance of which
is correlated with securities held in its portfolio. When the Fund
                                       I-2
<PAGE>   82
 
writes a call option, in return for an option premium, the Fund gives another
party the right to buy specified securities owned by the Fund at the exercise
price on or before the expiration date, in the case of an option on securities,
or agrees to pay to another party an amount based on any gain in a specified
securities index beyond a specified level on or before the expiration date, in
the case of an option on a securities index. The Fund may write call options to
earn income, through the receipt of option premiums. In the event the party to
which the Fund has written an option fails to exercise its rights under the
option because the value of the underlying securities is less than the exercise
price, the Fund will partially offset any decline in the value of the underlying
securities through the receipt of the option premium and will realize a greater
return than would have been realized on the underlying securities alone. By
writing a call option, however, the Fund limits its ability to sell the
underlying securities, and gives up the opportunity to profit from any increase
in the value of the underlying securities beyond the exercise price, while the
option remains outstanding. Writing a call option may involve correlation risk.
 
     The Fund may also write put options on securities or securities indices.
When the Fund writes a put option, in return for an option premium, the Fund
gives another party the right to sell to the Fund a specified security at the
exercise price on or before the expiration date, in the case of an option on a
security, or agrees to pay to another party an amount on any decline in a
specified securities index below a specified level on or before the expiration
date, in the case of an option on a securities index. The Fund may write put
options to earn income, through the receipt of option premiums. In the event the
party to which the Fund has written an option fails to exercise its right under
the option because the value of the underlying securities is greater than the
exercise price, the Fund will profit by the amount of the option premium. By
writing a put option, however, the Fund will be obligated to purchase the
underlying security at a price that may be higher than the market value of the
security at the time of exercise as long as the put option is outstanding.
Accordingly, when the Fund writes a put option it is exposed to a risk of loss
in the event the value of the underlying securities falls below the exercise
price, which loss potentially may substantially exceed the amount of option
premium received by the Fund for writing the put option. The Fund will write a
put option on a security or a securities index only if the Fund is using the put
as an anticipatory hedge or is writing the put in connection with trading
strategies involving combinations of options, for example, the sale and purchase
of options with identical expiration dates on the same security or index but
different exercise prices (a technique called a "spread"). Writing a put option
may involve substantial leverage risk.
 
     The Fund is also authorized to sell call or put options in connection with
closing out call or put options it has previously purchased.
 
     Other than with respect to closing transactions, the Fund will only write
call or put options that are "covered." A put option will be considered covered
if the Fund has segregated assets with respect to such option in the manner
described in "Risk Factors in Options, Futures and Currency Instruments" below.
A call option will be considered covered if the Fund owns the securities it
would be required to deliver upon exercise of the option (or, in the case of an
option on a securities index, securities which substantially replicate the
performance of such index) or owns a call option, warrant or convertible
instrument which is immediately exercisable for, or convertible into, such
security.
 
     Types of Options.  The Fund may engage in transactions in options on
securities or securities or interest rate indices on exchanges and in the
over-the-counter ("OTC") markets. In general, exchange-traded options have
standardized exercise prices and expiration dates and require the parties to
post margin against their obligations, and the performance of the parties'
obligations in connection with such options is guaranteed by the exchange or a
related clearing corporation. OTC options have more flexible terms negotiated
between the buyer and the seller, but generally do not require the parties to
post margin and are subject to greater credit risk. OTC options involve greater
liquidity risk. See "Additional Risk Factors of OTC Transactions; Limitations on
the Use of OTC Derivatives" below.
 
FUTURES
 
     The Fund may engage in transactions in futures and options thereon. Futures
are standardized, exchange-traded contracts which obligate a purchaser to take
delivery, and a seller to make delivery, of a specific amount
 
                                       I-3
<PAGE>   83
 
of a commodity at a specified future date at a specified price. No price is paid
upon entering into a futures contract. Rather, upon purchasing or selling a
futures contract the Fund is required to deposit collateral ("margin") equal to
a percentage (generally less than 10%) of the contract value. Each day
thereafter until the futures position is closed, the Fund will pay additional
margin representing any loss experienced as a result of the futures position the
prior day or be entitled to a payment representing any profit experienced as a
result of the futures position the prior day. Futures involve substantial
leverage risk.
 
     The sale of a futures contract for hedging purposes limits the Fund's risk
of loss through a decline in the market value of portfolio holdings correlated
with the futures contract prior to the futures contract's expiration date. In
the event the market value of the portfolio holdings correlated with the futures
contract increases rather than decreases, however, the Fund will realize a loss
on the futures position and a lower return on the portfolio holdings than would
have been realized without the purchase of the futures contract.
 
     The purchase of a futures contract as an anticipatory hedge may protect the
Fund from having to pay more for securities as a consequence of increases in the
market value for such securities during a period when the Fund was attempting to
identify specific securities in which to invest in a market the Fund believes to
be attractive. In the event that such securities decline in value or the Fund
determines not to complete an anticipatory hedge transaction in a futures
contract, however, the Fund may realize a loss relating to the futures position.
 
     The Fund will limit transactions in futures and options on futures
financial futures contracts (i.e., contracts for which the underlying asset is a
currency or securities or interest rate index). The Fund will also limit such
transactions to the extent necessary to prevent the Fund from being deemed a
"commodity pool" under regulations of the Commodity Futures Trading Commission.
 
FOREIGN EXCHANGE TRANSACTIONS
 
     The Fund may engage in spot and forward foreign exchange transactions and
currency swaps, purchase and sell options on currencies and purchase and sell
currency futures and related options thereon (collectively, "Currency
Instruments") predominantly for purposes of hedging against the decline in the
value of currencies in which its portfolio holdings are denominated against the
United States dollar.
 
     Forward foreign exchange transactions are OTC contracts to purchase or sell
a specified amount of a specified currency or multinational currency unit at a
price and future date set at the time of the contract. Spot foreign exchange
transactions are similar but require current, rather than future, settlement.
The Fund will enter into foreign exchange transactions predominantly for
purposes of hedging either a specific transaction or a portfolio position. The
Fund may enter into a foreign exchange transaction for purposes of hedging a
specific transaction by, for example, purchasing a currency needed to settle a
security transaction or selling a currency in which the Fund has received or
anticipates receiving a dividend or distribution. The Fund may enter into a
foreign exchange transaction for purposes of hedging a portfolio position by
selling forward a currency in which a portfolio position of the Fund is
denominated or by purchasing a currency in which the Fund anticipates acquiring
a portfolio position in the near future. The Fund may also hedge portfolio
positions through currency swaps, which are transactions in which one currency
is simultaneously bought for a second currency on a spot basis and sold for the
second currency on a forward basis. Forward foreign exchange transactions
involve substantial currency risk, and also involve credit risk and liquidity
risk.
 
     The Fund may also hedge against the decline in the value of a currency
against the United States dollar through use of currency futures or options
thereon. Currency futures are similar to forward foreign exchange transactions
except that futures are standardized, exchange-traded contracts. See "Futures"
above. Currency futures involve substantial currency risk, and also involve
leverage risk.
 
     The Fund may also hedge against the decline in the value of a currency
against the United States dollar through the use of currency options. Currency
options are similar to options on securities, but in consideration for an option
premium the writer of a currency option is obligated to sell (in the case of a
call option) or purchase (in the case of a put option) a specified amount of a
specified currency on or before the expiration date for a specified amount of
another currency. The Fund may engage in transactions in options on currencies
 
                                       I-4
<PAGE>   84
 
either on exchanges or OTC markets. See "Types of Options" above and "Additional
Risk Factors of OTC Transactions; Limitations on the Use of OTC Derivatives"
below. Currency options involve substantial currency risk, and may also involve
credit, leverage or liquidity risk.
 
     Although it is expected that the Fund will engage in transactions in
Currency Instruments predominantly for hedging purposes, the Fund may also
speculate in Currency Instruments in order to seek to enhance its total return.
To the extent that the Fund enters into a transaction in a Currency Instrument
for hedging purposes, the Fund will not hedge a currency in excess of the
aggregate market value of the securities which it owns (including receivables
for unsettled securities sales), or has committed to or anticipates purchasing,
which are denominated in such currency. The Fund may, however, hedge a currency
by entering into a transaction in a Currency Instrument denominated in a
currency other than the currency being hedged (a "cross-hedge"). The Fund will
only enter into a cross-hedge if the Manager believes that (i) there is a
demonstrable high correlation between the currency in which the cross-hedge is
denominated and the currency being hedged and (ii) executing a cross-hedge
through the currency in which the cross-hedge is denominated will be
significantly more cost-effective or provide substantially greater liquidity
than executing a similar hedging transaction by means of the currency being
hedged. To the extent that the Fund enters into a transaction in a Currency
Instrument for speculative purposes, the Fund may lose its entire investment or,
under certain circumstances, may be exposed to potential losses which
substantially exceed its original investment.
 
     Risk Factors in Hedging Foreign Currency Risks.  Hedging transactions
involving currency instruments have substantial risks, including correlation
risks. While the Fund's use of Currency Instruments to effect hedging strategies
is intended to reduce the volatility of the net asset value of the Fund's
shares, the net asset value of the Fund's shares will fluctuate. Moreover,
although Currency Instruments will be used with the intention of hedging against
adverse currency movements, transactions in Currency Instruments involve the
risk that anticipated currency movements will not be accurately predicted and
that the Fund's hedging strategies will be ineffective. To the extent that the
Fund hedges against anticipated currency movements which do not occur, the Fund
may realize losses, and lower its total return, as the result of its hedging
transactions. Furthermore, the Fund will only engage in hedging activities from
time to time and may not be engaging in hedging activities when movements in
currency exchange rates occur. It may not be possible for the Fund to hedge
against currency exchange rate movements, even if correctly anticipated, in the
event that (i) the currency exchange rate movement is so generally anticipated
that the Fund is not able to enter into a hedging transaction at an effective
price or (ii) the currency exchange rate movement relates to a market with
respect to which Currency Instruments are not available (such as certain
developing markets) and it is not possible to engage in effective foreign
currency hedging.
 
RISK FACTORS IN DERIVATIVES
 
     Use of Derivatives for hedging purposes involves correlation risk. If the
value of the Derivatives moves more or less than the value of the hedged
instruments the Fund will experience a gain or loss which will not be completely
offset by movements in the value of the hedged instruments.
 
     The Fund intends to enter transactions involving Derivatives only if there
appears to be a liquid secondary market for such instruments or, in the case of
illiquid instruments traded in OTC transactions, such instruments satisfy the
criteria set forth below under "Additional Risk Factors of OTC Transactions;
Limitations on the Use of OTC Derivatives." However, there can be no assurance
that, at any specific time, either a liquid secondary market will exist for a
Derivative or the Fund will otherwise be able to sell such instrument at an
acceptable price. It may therefore not be possible to close a position in a
Derivative without incurring substantial losses, if at all.
 
     Certain transactions in Derivatives (e.g., forward foreign exchange
transactions, futures transactions, sales of put options) may expose the Fund to
potential losses which exceed the amount originally invested by the Fund in such
instruments. When the Fund engages in such a transaction, the Fund will deposit
in a segregated account at its custodian liquid securities with a value at least
equal to the Fund's exposure, on a mark-to-market basis, to the transaction (as
calculated pursuant to requirements of the Securities and
 
                                       I-5
<PAGE>   85
 
Exchange Commission). Such segregation will ensure that the Fund has assets
available to satisfy its obligations with respect to the transaction, but will
not limit the Fund's exposure to loss.
 
ADDITIONAL RISK FACTORS OF OTC TRANSACTIONS, LIMITATIONS ON THE USE OF OTC
DERIVATIVES
 
     Certain Derivatives traded in OTC markets, including OTC options, may be
substantially less liquid than other instruments in which the Fund may invest.
The absence of liquidity may make it difficult or impossible for the Fund to
sell such instruments promptly at an acceptable price. The absence of liquidity
may also make it more difficult for the Fund to ascertain a market value for
such instruments. The Fund will therefore acquire illiquid OTC instruments (i)
if the agreement pursuant to which the instrument is purchased contains a
formula price at which the instrument may be terminated or sold or (ii) for
which the Manager anticipates the Fund can receive on each business day at least
two independent bids or offers, unless a quotation from only one dealer is
available, in which case that dealer's quotation may be used.
 
     The staff of the Securities and Exchange Commission has taken the position
that purchased OTC options and the assets underlying written OTC options are
illiquid securities. The Fund has therefore adopted an investment policy
pursuant to which it will not purchase or sell OTC options (including OTC
options on futures contracts) if, as a result of such transactions, the sum of
the market value of OTC options currently outstanding which are held by the
Fund, the market value of the securities underlying OTC call options currently
outstanding which have been sold by the Fund and margin deposits on the Fund's
outstanding OTC options exceeds 15% of the total assets of the Fund, taken at
market value, together with all other assets of the Fund which are deemed to be
illiquid or are otherwise not readily marketable. However, if an OTC option is
sold by the Fund to a dealer in U.S. government securities recognized as a
"primary dealer" by the Federal Reserve Bank of New York and the Fund has the
unconditional contractual right to repurchase such OTC option at a predetermined
price, then the Fund will treat as illiquid such amount of the underlying
securities as is equal to the repurchase price less the amount by which the
option is "in-the-money" (i.e., current market value of the underlying security
minus the option's exercise price).
 
     Because Derivatives traded in OTC markets are not guaranteed by an exchange
or clearing corporation and generally do not require payment of margin, to the
extent that the Fund has unrealized gains in such instruments or has deposited
collateral with its counterparty the Fund is at risk that its counterparty will
become bankrupt or otherwise fail to honor its obligations. The Fund will
attempt to minimize the risk that a counterparty will become bankrupt or
otherwise fail to honor its obligations by engaging in transactions in
Derivatives traded in OTC markets only with financial institutions which have
substantial capital or which have provided the Fund with a third-party guaranty
or other credit enhancement.

                 RATINGS OF DEBT SECURITIES AND PREFERRED STOCK
 
DESCRIPTION OF MOODY'S INVESTORS SERVICE, INC.'S ("MOODY'S") LONG-TERM DEBT
RATINGS
 
<TABLE>
<S>    <C>
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-edged." 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 risk
       appear somewhat larger than in Aaa securities.
A      Bonds which are rated A possess many favorable investment
       attributes and are to be considered as upper-medium-grade
       obligations. Factors giving security to principal and
       interest are considered adequate, but elements may be
       present which suggest a susceptibility to impairment
       sometime in the future.
Baa    Bonds which are rated Baa are considered as medium-grade
       obligations, i.e., they are neither highly protected nor
       poorly secured. Interest payment and principal security
       appear adequate for the present but certain protective
       elements may be lacking or may be characteristically
       unreliable over any great length of time. Such bonds lack
       outstanding investment characteristics and in fact have
       speculative characteristics as well.
Ba     Bonds which are rated Ba are judged to have speculative
       elements; their future cannot be considered as well-assured.
       Often the protection of interest and principal payments may
       be very moderate and thereby not well safeguarded during
       both good and bad times over the future. Uncertainty of
       position characterizes bonds in this class.
B      Bonds which are rated B generally lack characteristics of
       the desirable investment. Assurance of interest and
       principal 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.
</TABLE>
 
     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.
 
DESCRIPTION OF MOODY'S SHORT-TERM DEBT RATINGS
 
     Moody's employs the following three designations, all judged to be
investment grade, to indicate the relative repayment ability of rated issuers:
 
     Issuers rated Prime-1 (or supporting institutions) have a superior ability
for repayment of senior short-term debt obligations. Prime-1 repayment ability
will often be evidenced by the many following characteristics: leading market
positions in well established industries; high rates of return on funds
employed; conservative capitalization structure with moderate reliance on debt
and ample asset protection; broad margins in earnings 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.
                                      II-1
<PAGE>   87
 
     Issuers rated Prime-2 (or supporting institutions) have a strong ability
for repayment of senior short-term debt 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 senior short-term debt obligations. The effect of
industry characteristics and market composition may be more pronounced.
Variability in earnings and profitability may result in changes in the level of
debt protection measurements and 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 MOODY'S PREFERRED STOCK RATINGS
 
     Because of the fundamental differences between preferred stocks and bonds,
a variation of our familiar bond rating symbols is used in the quality ranking
of preferred stock. The symbols, presented below, are designed to avoid
comparison with bond quality in absolute terms. It should always be borne in
mind that preferred stock occupies a junior position to bonds within a
particular capital structure and that these securities are rated within the
universe of preferred stocks.
 
<TABLE>
<S>    <C>
aaa    An issue which is rated "aaa" is considered to be a
       top-quality preferred stock. This rating indicates good
       asset protection and the least risk of dividend impairment
       within the universe of preferred stocks.
aa     An issue which is rated "aa" is considered to be a
       high-grade preferred stock. This rating indicates that there
       is a reasonable assurance the earnings and asset protection
       will remain relatively well maintained in the foreseeable
       future.
a      An issue which is rated "a" is considered to be an
       upper-medium grade preferred stock. While risks are judged
       to be somewhat greater than in the "aaa" and "aa"
       classification, earnings and asset protection are,
       nevertheless, expected to be maintained at adequate levels.
baa    An issue which is rated "baa" is considered to be a
       medium-grade preferred stock, neither highly protected nor
       poorly secured. Earnings and asset protection appear
       adequate at present but may be questionable over any great
       length of time.
ba     An issue which is rated "ba" is considered to have
       speculative elements and its future cannot be considered
       well assured. Earnings and asset protection may be very
       moderate and not well safeguarded during adverse periods.
       Uncertainty of position characterizes preferred stocks in
       this class.
b      An issue which is rated "b" generally lacks the
       characteristics of a desirable investment. Assurance of
       dividend payments and maintenance of other terms of the
       issue over any long period of time may be small.
caa    An issue which is rated "caa" is likely to be in arrears on
       dividend payments. This rating designation does not purport
       to indicate the future status of payments.
ca     An issue which is rated "ca" is speculative in a high degree
       and is likely to be in arrears on dividends with little
       likelihood of eventual payments.
c      This is the lowest rated class of preferred or preference
       stock. Issues so rated can thus be regarded as having
       extremely poor prospects of ever attaining any real
       investment standing.
</TABLE>
 
     Note:  Moody's applies numerical modifiers 1, 2, and 3 in each rating
classification: the modifier 1 indicates that the security ranks in the higher
end of its generic rating category; the modifier 2 indicates a mid-range ranking
and the modifier 3 indicates that the issue ranks in the lower end of its
generic rating category.

DESCRIPTION OF STANDARD & POOR'S ("STANDARD & POOR'S") ISSUE CREDIT RATING
DEFINITIONS
 
     A Standard & Poor's issue credit rating is a current opinion of the
creditworthiness of an obligor with respect to a specific financial obligation,
a specific class of financial obligations, or a specific financial program
(including ratings on medium term note programs and commercial paper programs).
It takes into consideration the creditworthiness of guarantors, insurers, or
other forms of credit enhancement on the obligation and takes into account the
currency in which the obligation is denominated.
 
     The issue credit 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.
 
     Issue credit ratings are based on current information furnished by the
obligors or obtained by Standard & Poor's from other sources it considers
reliable. Standard & Poor's does not perform an audit in connection with any
credit rating and may, on occasion, rely on unaudited financial information.
Credit ratings may be changed, suspended, or withdrawn as a result of changes
in, or unavailability of, such information, or based on other circumstances.
 
     The ratings are based, in varying degrees, on the following considerations:
 
          I. Likelihood of payment capacity and willingness of the obligor to
     meet its financial commitment on an obligation in accordance with the terms
     of obligation;
 
          II. Nature of and provisions of the obligation; and
 
          III. Protection afforded by, and relative position of, the obligation
     in the event of bankruptcy, reorganization, or other arrangement under the
     laws of bankruptcy and other laws affecting creditors' rights.
 
LONG-TERM ISSUE CREDIT RATINGS
 
<TABLE>
<C>   <S>
 AAA  An obligation rated "AAA" has the highest rating assigned by
      Standard & Poor's. The obligor's capacity to meet its
      financial commitment on the obligation is extremely strong.
  AA  An obligation rated "AA" differs from the highest rated
      obligations only in small degree. The obligor's capacity to
      meet its financial commitment on the obligation is very
      strong.
   A  An obligation rated "A" is somewhat more susceptible to the
      adverse effects of changes in circumstances and economic
      conditions than obligations in higher-rated categories.
      However, the obligor's capacity to meet its financial
      commitment on the obligation is still strong.
 BBB  An obligation 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  An obligation rated "BB," "B," "CCC," "CC" and "C" is
   B  regarded as having significant speculative characteristics.
 CCC  "BB" indicates the least degree of speculation and "CCC" the
      highest degree of speculation. While such bonds will likely
      have some quality and protective characteristics, these may
      be outweighed by large uncertainties or major exposures to
      adverse conditions.
  CC  An obligation rated "CCC" is in arrears on dividends or
      sinking fund payments, but is currently paying.
   C  An obligation that is a nonpaying issue.
   D  An obligation rated "D" is in payment default. The "D"
      rating category is used when payments on an obligation are
      not made on the date due even if the applicable grace period
      has not expired, unless Standard & Poor's believes that such
      payments will be made during such grace period. The "D"
      rating also will be used upon the filing of a bankruptcy
      petition or the taking of a similar action if payments on an
      obligation are jeopardized.
</TABLE>
 
     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.
 
                                      II-3

SHORT-TERM ISSUE CREDIT RATINGS
 
<TABLE>
<C>   <S>
 A-1  A short-term obligation rated "A-1" is rated in the highest
      category by Standard & Poor's. The obligor's capacity to
      meet its financial commitment on the obligation is strong.
      Within this category, certain obligations are designated
      with a plus sign (+). This indicates that the obligor's
      capacity to meet its financial commitment on these
      obligations is extremely strong.
 A-2  A short-term obligation rated "A-2" is somewhat more
      susceptible to the adverse effects of changes in
      circumstances and economic conditions than obligations in
      higher rating categories. However, the obligor's capacity to
      meet its financial commitment on the obligation is
      satisfactory.
 A-3  A short-term obligation rated "A-3" 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.
   B  A short-term obligation rated "B" is regarded as having
      significant speculative characteristics. The obligor
      currently has the capacity to meet its financial commitment
      on the obligation; however, it faces major ongoing
      uncertainties which could lead to the obligor's inadequate
      capacity to meet its financial commitment on the obligation.
   C  A short-term obligation rated "C" is currently vulnerable to
      nonpayment and is dependent upon favorable business,
      financial, and economic conditions for the obligor to meet
      its financial commitment on the obligation.
   D  A short-term obligation rated "D" is in payment default. The
      "D" rating category is used when payments on an obligation
      are not made on the date due even if the applicable grace
      period has not expired, unless Standard & Poor's believes
      that such payments will be made during such grace period.
      The "D" rating also will be used upon the filing of a
      bankruptcy petition or the taking of a similar action if
      payments on an obligation are jeopardized.

DESCRIPTION OF STANDARD & POOR'S PREFERRED STOCK RATINGS DEFINITIONS
 
     A Standard & Poor's preferred stock rating is an assessment of the capacity
and willingness of an issuer to pay preferred stock dividends and any applicable
sinking fund obligations. A preferred stock rating differs from a bond rating
inasmuch as it is assigned to an equity issue, which is intrinsically different
from, and subordinated to, a debt issue. Therefore, to reflect this difference,
the preferred stock rating symbol will normally not be higher than the debt
rating symbol assigned to, or that would be assigned to, the senior debt of the
same issuer.
 
     A preferred stock rating is not a recommendation to purchase, sell, or hold
a security, inasmuch as it does not comment as to market price or suitability
for a particular investor.
 
     The ratings are based on current information furnished to Standard & Poor's
by the issuer or obtained by Standard & Poor's from other sources it considers
reliable. Standard & Poor's does not perform an audit in connection with any
rating and may, on occasion, rely on unaudited financial information. The
ratings may be changed, suspended, or withdrawn as a result of changes in, or
unavailability of, such information, or based on other circumstances.
 
     The ratings are based on the following considerations:
 
          I. Likelihood of payment-capacity and willingness of the issuer to
     meet the timely payment of preferred stock dividends and any applicable
     sinking fund requirements in accordance with the terms of the obligation;
 
          II. Nature of, and provisions of, the issue;
 
          III. Relative position of the issue in the event of bankruptcy,
     reorganization, or other arrangement under the laws of bankruptcy and other
     laws affecting creditors' rights.

PREFERRED STOCK RATINGS
 
<TABLE>
<C>   <S>
 AAA  This is the highest rating that may be assigned by Standard
      & Poor's to a preferred stock issue and indicates an
      extremely strong capacity to pay the preferred stock
      obligations.
  AA  A preferred stock issue rated AA also qualifies as a
      high-quality, fixed-income security. The capacity to pay
      preferred stock obligations is very strong, although not as
      overwhelming as for issues rated AAA.
   A  An issue rated A is backed by a sound capacity to pay the
      preferred stock obligations, although it is somewhat more
      susceptible to the adverse effects of changes in
      circumstances and economic conditions.
 BBB  An issue rated BBB is regarded as backed by an adequate
      capacity to pay the preferred stock obligations. Whereas it
      normally exhibits adequate protection parameters, adverse
      economic conditions or changing circumstances are more
      likely to lead to a weakened capacity to make payments for a
      preferred stock in this category than for issues in the A
      category.
  BB  Preferred stock rated BB, B, and CCC are regarded, on
   B  balance, as predominantly speculative with respect to the
 CCC  issuer's capacity to pay preferred stock obligations. BB
      indicates the lowest degree of speculation and CCC the
      highest. While such issues will likely have some quality and
      protective characteristics, these are outweighed by large
      uncertainties or major risk exposures to adverse conditions.
  CC  The rating CC is reserved for a preferred stock issue that
      is in arrears on dividends or sinking fund payments, but
      that is currently paying.
   C  A preferred stock rated C is a nonpaying issue.
   D  A preferred stock rated D is a nonpaying issue with the
      issuer in default on debt instruments.
N.R.  This indicates that no rating has been requested, that there
      is insufficient information on which to base a rating, or
      that Standard & Poor's does not rate a particular type of
      obligation as a matter of policy.
</TABLE>
 
     Plus (+) or minus (-): To provide more detailed indications of preferred
stock quality, 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.

ITEM 24.  PERSONS CONTROLLED BY OR UNDER COMMON CONTROL WITH REGISTRANT.
 
     The Registrant is not controlled by or under common control with any other
person.
 
ITEM 25.  INDEMNIFICATION.
 
     Reference is made to Article V of Registrant's Amended and Restated
Articles of Incorporation, Article VI of Registrant's By-laws, Section 2-418 of
the Maryland General Corporation Law and Section 9 of the Class A, Class B,
Class C and Class D Distribution Agreements.
 
     Article VI of the By-Laws provides that each officer and director of the
Registrant shall be indemnified by the Registrant to the full extent permitted
under the General Laws of the State of Maryland, except that such indemnity
shall not protect any such person against any liability to the Registrant or any
stockholder thereof to which such person would otherwise be subject by reason of
willful misfeasance, bad faith, gross negligence or reckless disregard of the
duties involved in the conduct of his office. Absent a court determination that
an officer or director seeking indemnification was not liable on the merits or
guilty of willful misfeasance, bad faith, gross negligence or reckless disregard
of the duties involved in the conduct of his office, the decision by the
Registrant to indemnify such person must be based upon the reasonable
determination of independent counsel or non-party independent directors, after
review of the facts, that such officer or director is not guilty of willful
misfeasance, bad faith, gross negligence or reckless disregard of the duties
involved in the conduct of his office.
 
     Each officer and director of the Registrant claiming indemnification within
the scope of Article VI of the By-Laws shall be entitled to advances from the
Registrant for payment of the reasonable expenses incurred by him in connection
with proceedings to which he is a party in the manner and to the full extent
permitted under the General Laws of the State of Maryland; provided, however,
that the person seeking indemnification shall provide to the Registrant a
written affirmation of his good faith belief that the standard of conduct
necessary for indemnification by the Registrant has been met and a written
undertaking to repay any such advance, if it should ultimately be determined
that the standard of conduct has not been met, and provided further that at
least one of the following additional conditions is met: (a) the person seeking
indemnification shall provide a security in form and amount acceptable to the
Registrant for his undertaking; (b) the Registrant is insured against losses
arising by reason of the advance; (c) a majority of a quorum of non-party
independent directors, or independent legal counsel in a written opinion, shall
determine, based on a review of facts readily available to the Registrant at the
time the advance is proposed to be made, that there is reason to believe that
the person seeking indemnification will ultimately be found to be entitled to
indemnification.
 
     The Registrant may purchase insurance on behalf of an officer or director
protecting such person to the full extent permitted under the General Laws of
the State of Maryland from liability arising from his activities as officer or
director of the Registrant. The Registrant, however, may not purchase insurance
on behalf of any
 
                                       C-2
<PAGE>   94
 
officer or director of the Registrant that protects or purports to protect such
person from liability to the Registrant or to its stockholders to which such
officer or director would otherwise be subject by reason of willful misfeasance,
bad faith, gross negligence, or reckless disregard of the duties involved in the
conduct of his office.
 
     The Registrant may indemnify, make advances or purchase insurance to the
extent provided in Article VI of the By-Laws on behalf of an employee or agent
who is not an officer or director of the Registrant.
 
     In Section 9 of the Class A, Class B, Class C and Class D Distribution
Agreements relating to the securities being offered hereby, the Registrant
agrees to indemnify the Distributor and each person, if any, who controls the
Distributor within the meaning of the Securities Act of 1933 (the "1933 Act"),
against certain types of civil liabilities arising in connection with the
Registration Statement or Prospectus and Statement of Additional Information.
 
     Insofar as indemnification for liabilities arising under the 1933 Act may
be permitted to Directors, officers and controlling persons of the Registrant
and the principal underwriter pursuant to the foregoing provisions or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the 1933 Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a Director, officer, or controlling
person of the Registrant and the principal underwriter in connection with the
successful defense of any action, suit or proceeding) is asserted by such
Director, officer or controlling person or the principal underwriter in
connection with the shares being registered, the Registrant 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 1933 Act and
will be governed by the final adjudication of such issue.
