Key Facts [CLIPART]

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.

Intermediate-term debt
securities -- bonds that have a final maturity ranging from five to fifteen
years.

Current Income -- income from interest or dividends.


THE MERRILL LYNCH INTERMEDIATE GOVERNMENT BOND FUND AT A GLANCE
- --------------------------------------------------------------------------------

What is the Fund's investment objective?

The Fund's investment objective is to seek the highest possible current income
consistent with the protection of capital afforded by investing primarily in
intermediate-term debt securities issued or guaranteed by the U.S. Government,
its agencies or instrumentalities. We cannot guarantee that the Fund will
achieve its goals.

What are the Fund's main investment strategies?

The Fund invests in a portfolio of bonds and other debt securities that are
issued or guaranteed by the U.S. Government or U.S. Government agencies and
organizations. The Fund may invest a portion of its portfolio in mortgage-backed
securities issued or guaranteed by government sponsored enterprises. The Fund
may also invest in securities linked to an interest rate or other index. The
Fund may loan portfolio securities and enter into securities repurchase
agreements and purchase securities on a when-issued or forward commitment basis.
Under normal circumstances, the Fund will maintain a dollar-weighted average
maturity of six to eight years.

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 fluctuate. These changes may occur in response to
interest rate changes or other factors that may affect a particular issuer or
obligation. Generally, when interest rates go up, the value of debt instruments
goes down. If the value of the Fund's investments goes down, you may lose money.

Mortgage-backed securities may be more volatile than other government debt
securities and carry the risk of prepayment before maturity.

Who should invest?

The Fund may be an appropriate investment for you if you:

   o  Are looking for current income.

   o  Are investing with medium term goals in mind and want to focus on U.S.
      Government 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 D shares for the past ten calendar years. 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 of the Fund's
Class D shares for one, five and ten years with those of the Merrill Lynch U.S.
Treasury Bond Index and the Merrill Lynch U.S. Treasury & Government Agency Bond
Index. 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.
Listed below are some of the main types of expenses, which all mutual funds may
charge:

Expenses paid directly by the shareholder:

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

Expenses paid indirectly by the shareholder (These costs are deducted from the
Fund's total assets): Annual Fund Operating Expenses -- expenses that cover the
costs of operating the Fund.

Management Fee -- a fee paid to the Investment Adviser for managing the Fund.

Distribution Fees -- fees used to support the Fund's marketing and distribution
efforts, such as compensating Financial Consultants.

Service (Account Maintenance) Fees -- fees used to compensate securities dealers
for account maintenance activities.

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.

your investment):                   Class A   Class B(a)   Class C    Class D(h)

(a) Class B shares automatically convert to Class D shares about ten years after
    you buy them and 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 calls the "Service Fee" an "Account Maintenance Fee."Account
    Maintenance is the term used in this Prospectus and in 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. Distribution and
    Account Maintenance Fees reflect the maximum amount the Fund would
    contractually be subject to pay. The Distributor voluntarily waived Class C
    distribution fees for the fiscal year ended October 31, 1998.
(e) 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 October
    31, 1998, the Fund paid the Transfer Agent fees totaling $9,518. The
    Investment Adviser provides accounting services to the Fund at its cost. For
    the fiscal year ended October 31, 1998, the Fund reimbursed the Investment
    Adviser $37,878 for these services.
(f) For the fiscal year ended October 31, 1998, Merrill Lynch Asset Management,
    L.P. ("MLAM") voluntarily waived a portion of the management fee due from
    the Fund and reimbursed the Fund for a portion of other expenses. As MLAM
    may discontinue its waiver of such fees and reimbursement of expenses, the
    table above has been restated to assume the absence of any such waiver or
    reimbursement. During the fiscal year ended October 31, 1998, MLAM waived
    management fees and reimbursed expenses totaling 0.33% for Class A shares,
    0.31% for Class B shares, 0.31% for Class C shares, and 0.33% for Class D
    shares after which the Fund's total expense ratio was 0.76% for Class A
    shares, 1.23% for Class B shares, 0.95% for Class C shares and 0.89% for
    Class D shares.
(g) In addition, Merrill Lynch may charge clients a processing fee (currently
    $5.35) when a client buys or redeems shares.
(h) The shares of the Fund in existence prior to its reorganization at the close
    of business on February 14, 1997 have been reclassified as Class D shares.

Key Facts [CLIPART]

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 [CLIPART]

ABOUT THE
PORTFOLIO MANAGER

Ralph A. DeCesare is a Vice President and the portfolio manager of the Fund.
Mr. DeCesare has been a Director of the Investment Adviser since 1998 and was a
Vice President of the Investment Adviser from 1993 to 1997.

ABOUT THE
INVESTMENT ADVISER

The Fund is managed by
Merrill Lynch Asset Management.


HOW THE FUND INVESTS
- --------------------------------------------------------------------------------

The Fund's investment objective is to seek the highest possible current income
consistent with the protection of capital afforded by investing primarily in
intermediate-term debt securities issued or guaranteed by the U.S. Government,
its agencies or instrumentalities. In other words, the Fund's main goal is to
generate current income. The Fund tries to do this by investing in bonds and
other debt securities that are issued or guaranteed by the U.S. Government or
U.S. Government agencies and organizations. Under normal circumstances all or
substantially all of the Fund's assets will be invested in those securities.
Under normal circumstances, the Fund will maintain a dollar-weighted average
maturity of six to eight years. We cannot guarantee that the Fund will achieve
its goals.

The Fund will invest in a variety of government securities. Certain securities,
such as U.S. Treasury obligations are direct obligations of the U.S. Government.
The Fund also invests in securities that are issued by government-sponsored
enterprises or agencies but are not direct obligations of the U.S. Government.
These securities are, however, backed by the credit of the particular agency or
government-sponsored enterprise that issued the securities and are generally
considered to have a low risk of default by the issuer.

The Fund may invest a portion of its assets in various types of mortgage-backed
securities issued or guaranteed by government-sponsored enterprises such as the
Federal National Mortgage Association. Mortgage-backed securities are backed by
and are repaid from a pool of mortgage loans on residential or commercial real
estate. The actual yield and maturity of many mortgage-backed securities will
vary as the underlying mortgages are paid off more rapidly in response to
falling interest rates or more slowly in response to rising interest rates.

The Fund may also invest in securities that provide a return based on an
interest rate or index. For example, the Fund may invest in a security that
increases in value with a rise in the price of a particular index. In some
cases, the return of the security may be inversely related to the price of the
index. This means that the value of the security will rise as the price of the
index falls and vice versa. Certain indexed securities can provide a degree of
leverage because they may increase or decrease at a greater rate than the price
of the index on which the security is based. Indexed securities also are subject
to the risks related to the underlying index.

<PAGE>

[CLIPART] Details About the Fund

The Fund may lend its portfolio securities under lending arrangements with
brokers, dealers and financial institutions. When lending portfolio securities,
the Fund will receive collateral in cash or securities issued or guaranteed by
the U.S. government equal to at least 100% of the market value of the loaned
securities plus accrued interest. This collateral will be invested by the Fund
in short-term securities and the Fund will retain the income earned from these
investments. The Fund may enter into repurchase agreements with a member bank of
the Federal Reserve System or a primary dealer in the U.S. Government securities
or an affiliate of such dealer. The Fund may also purchase securities on a
when-issued basis or forward commitment basis or sell such securities for
delayed delivery.

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.

Interest Rate Risk -- Prices of bonds generally increase when interest rates
decline and decrease when interest rates increase. This risk is known as
interest rate risk. Prices of longer term securities generally fluctuate more in
response to interest rate changes than do prices of shorter term securities.

Mortgage-Backed Securities -- The value of mortgage-backed securities, like that
of traditional fixed-income securities, typically increases when interest rates
fall and decreases when interest rates rise. However, mortgage-backed securities
are also subject to the risk of prepayment. In a period of declining interest
rates, borrowers may pay what they owe on the underlying assets more quickly
than anticipated, which will reduce the yield to maturity and the average life
of the mortgage-backed securities. In addition, when the Fund reinvests the
proceeds of a prepayment it will likely receive an interest rate lower than the
rate on the security that was prepaid. In a period of rising interest rates,
prepayments may occur at a slower than expected rate. As a result, the average
maturity of the Fund's portfolio will increase. The value of long-term
securities generally changes more widely in response to changes in interest
rates than short-term securities.


8                MERRILL LYNCH INTERMEDIATE GOVERNMENT BOND FUND               

<PAGE>

Indexed and Inverse-Indexed Securities -- The Fund may invest in securities
whose potential returns are directly related to changes in an underlying index
or interest rate, known as indexed securities. The return on indexed securities
will rise when the underlying index or interest rate rises and fall when the
index or interest rate falls. The Fund may also invest in securities whose
return is inversely related to changes in an interest rate. In general,
inverse-indexed securities change in value in a manner that is opposite to most
bonds-that is, interest rates on these securities will decrease when interest
rates increase in value and increase in value when interest rates decrease.
Investments in inverse-indexed securities may subject the Fund to the risks of
reduced or eliminated interest payments and losses of principal. In addition,
certain indexed securities and inverse-indexed securities may increase or
decrease in value at a greater rate than the underlying interest rate, which
effectively leverages the Fund's investment. As a result, the market value of
such securities will generally be more volatile than that of fixed rate
securities.

Securities Lending -- Securities lending involves the risk that the borrower to
which the Fund has loaned its securities may not return the securities in a
timely manner or at all. As a result, the Fund may suffer costs and delay in
recovering the loaned securities. In addition, if the Fund does not get back the
securities it loaned and the value of the collateral the Fund received in return
or the loaned securities falls, the Fund could lose money.

When-Issued and Delayed-Delivery Securities -- When-issued and delayed-delivery
securities involve the risk that the security the Fund buys will lose value
prior to its delivery to the Fund. There also is the risk that the security will
not be issued or that the other party will not meet its obligation, in which
case the Fund may lose the investment opportunity for the assets it has set
aside to pay for the security and any gain in the security's price.

Your Account [CLIPART]

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. It
should be noted that Class C shares are available only through the Exchange
Privilege and may not be purchased except through exchange of Class C shares of
another Fund advised by the Investment Adviser. 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 pay a sales charge at the
time of purchase. If you buy Class D shares, you also pay an ongoing account
maintenance fee of 0.10%. If you select Class B or C shares, you can invest the
full amount of your purchase price, but you will be subject to a distribution
fee and account maintenance fee payable over time and possibly a deferred sales
charge when you sell shares. You may be eligible for a sales charge waiver. See
below.

If you purchase Class B or C shares, you pay a distribution fee of 0.25% and an
account maintenance fee of 0.25% on an ongoing basis. 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 Fund's shares are distributed by Merrill Lynch Funds Distributor, a division
of Princeton Funds Distributor, Inc., an affiliate of Merrill Lynch.

* The shares of the Fund in existence prior to its reorganization at the close
of business on February 14, 1997 have been reclassified as Class D shares.
Although purchasers of Class D shares generally will pay an initial sales
charge, if you have held shares of the Fund since prior to its reorganization,
you will not pay any sales charge with respect to either your "reclassified"
Class D shares or any Class D shares you may purchase in the future. See page 11

 *  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 0.20% of the lesser of the original cost of the shares being redeemed or
    your redemption proceeds. A sales charge of 0.30% will be charged on
    purchases of $1,000,000 or more of Class A or Class D shares by certain
    employer sponsored retirement or savings plans.

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:

    o   Purchases under a Right of Accumulation or Letter of Intent.

    o   TMA(SM) Managed Trusts.

    o   Certain Merrill Lynch investment or central asset accounts.

    o   Certain employer-sponsored retirement or savings plans.

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


12               MERRILL LYNCH INTERMEDIATE GOVERNMENT BOND FUND        

<PAGE>

    o   Certain investors, including directors of Merrill Lynch mutual funds and
        Merrill Lynch employees.

    o   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 an 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 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 0.25% and account
maintenance fees of 0.25% each year. 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.

 If you redeem Class B or Class C shares within one year after purchase, you may
be charged a deferred sales charge of 1.00%. 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.

Class B Shares

The deferred sales charge relating to Class B shares will be reduced or waived
in certain circumstances, such as:

    o   Certain post-retirement withdrawals from an IRA or other retirement plan
        if you are over 59 1/2 years old.

    o   Redemption by certain eligible 401(a) and 401(k) plans and group plans
        participating in certain retirement plan rollovers.

    o   Redemption in connection with participation in certain Merrill Lynch
        fee-based programs.

    o   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 temination of an account in which Fund
        shares are held.

    o   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 ten
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 exchange Class B shares with a ten-year conversion schedule
for Class B shares with an eight year conversion


14               MERRILL LYNCH INTERMEDIATE GOVERNMENT BOND FUND     

<PAGE>

schedule, or vice versa, the conversion schedule applicable to the Class B
shares acquired in the exchange will apply. If you acquire your Class B shares
in an exchange from another fund, the Fund's ten-year conversion schedule will
apply. If you exchange your Class B shares in the Fund for Class B shares of
another fund, 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

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 though the Merrill Lynch Systematic Withdrawal Plan. The deferred
sales charge relating to Class C shares may also be reduced or waived for
withdrawal through the Merrill Lynch Systematic Withdrawal Plan of up to 10% per
year of the account value at the time the plan is established and in connection
with involuntary termination of an account in which Fund shares are held.

Class C shares do not offer a conversion privilege.

                                                       Securities dealers, including Merrill Lynch, may charge a fee to
                                                       process a redemption of shares. Merrill Lynch currently charges a

                                                       Each class of Fund shares is generally exchangeable for shares of

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 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--ordinary income and capital
gains paid to shareholders. Dividends
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. The reason? 
If you buy shares when a fund has 
realized but not yet distributed 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 dividend. 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 AND TAXES
- --------------------------------------------------------------------------------

The Fund will distribute any net investment income monthly, and any net realized
capital gains annually. If your account is with Merrill Lynch and you would like
to receive dividends in cash, contact your Merrill Lynch Financial Consultant.
If your account is with the Transfer Agent and you would like to receive
dividends in cash, contact the Transfer Agent.

You will pay tax on dividends 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. Under normal circumstances, the Fund expects that its
distributions will consist primarily of ordinaty income. Capital gain dividends
are generally taxed at different rates than ordinary dividends.

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.

By law, the Fund must withhold 31% of your dividends 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 [CLIPART]

MERRILL LYNCH ASSET MANAGEMENT
- --------------------------------------------------------------------------------

Merrill Lynch Asset Management, the Fund's Investment Adviser, manages
the Fund's investments and its business operations under the overall supervision
of the Fund's Board of Trustees. The Investment Adviser has the responsibility
for making all investment decisions for the Fund. The Investment Adviser has a
sub-advisory agreement with Merrill Lynch Asset Management U.K. Limited, an
affiliate, under which the Investment Adviser may pay a fee for services it
receives. The Fund pays the Investment Adviser a fee at the annual rate of 0.40%
of the average daily net assets of the Fund. For the fiscal year ended October
31, 1998 the Investment Adviser received a management fee of $150,322 (based on
average daily net assets of approximately $37.7 million), $122,202 of which the
Investment Adviser voluntarily reimbursed to the Fund.

Merrill Lynch Asset Management is part of Merrill Lynch Asset Management Group,
which had approximately $507 billion in investment company and other portfolio
assets under management as of January 1999. 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's 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 companies in which the
Fund invests, and this could hurt the Fund's investment returns.

FINANCIAL HIGHLIGHTS
- --------------------------------------------------------------------------------

The financial highlights table is intended to help you understand the Fund's
financial performance for the past five years. Certain information reflects
financial results for a single Fund share. The total returns in the table
represent the rate that an investor would have earned on an investment in the
Fund (assuming reinvestment of all dividends and distributions). This
information has been audited by Deloitte & Touche LLP, whose report, along with
the Fund's financial statements, are included in the Fund's annual report to
shareholders, which is available upon request.

In connection with its reorganization at the close of business on February 14,
1997, the Fund changed its investment objective. For the period from the
commencement of the Fund's operations through its reorganization at the close of
business on February 14, 1997, the portfolio of the Fund has consisted primarily
of securities issued by the U.S. Government and its agencies and
instrumentalities. The average maturity of the Fund's portfolio during this
period (generally ranging from two to five years) has been somewhat shorter than
the average maturity of the Fund of six to eight years following the change in
its investment objective upon its reorganization. As a result, the financial
information in the table below for operations of the Fund prior to its
reorganization may not be indicative of its performance following its
reorganization.

                       INVESTMENT OBJECTIVES AND POLICIES

     The Fund is a diversified,  open-end  management  investment  company.  The
investment  objective of the Fund is to seek the highest possible current income
consistent  with the  protection of capital  afforded by investing  primarily in
intermediate-term  debt securities issued or guaranteed by the U.S.  Government,
its  agencies  or  instrumentalities.   Under  normal   circumstances,   all  or
substantially  all of the Fund's  assets will be  invested  in such  securities.
Under normal market conditions, the Fund will maintain a dollar-weighted average
maturity of six to eight years. For purposes of applying these limits,  the Fund
will consider a fixed-income  security's maturity to be its stated maturity (the
date the issuer is scheduled  to make its final  payment of  principal),  except
that

      o  for a security  with an  unconditional  put entitling a Fund to receive
         the  security's  approximate  amortized  cost,  the  maturity  will  be
         considered to be the next put date;

      o  for mortgage-backed and other amortizing securities,  the maturity will
         be considered to be the average life  remaining  (the length of time it
         is expected to take to retire half of the remaining  principal  through
         amortizing  payments)  based on  prepayment  assumptions  that the Fund
         manager believes to be reasonable;

      o  for a variable or floating rate investment grade security that the Fund
         manager believes will have a market value approximating  amortized cost
         on the next interest  reset date, the maturity will be considered to be
         the next reset date; and

      o  for a Fund that operates under SEC rules that  specifically  define the
         maturity of a security, the maturity of a security will be the maturity
         determined in a manner consistent with the SEC rules.

     Certain of the  securities  in which the Fund invests are  supported by the
full faith and credit of the U.S. Government, such as U.S. Treasury obligations.
Other of the  securities in which the Fund invests are not supported by the full
faith  and  credit of the U.S.  Government  but are  issued  by U.S.  Government
agencies, instrumentalities or government-sponsored enterprises. Such securities
are generally  supported  only by the credit of the agency,  instrumentality  or
enterprise  issuing the  security  and are  generally  considered  to have a low
principal risk. However, because of the longer-term maturities of the securities
in which the Fund will invest,  interest rate  fluctuations may adversely affect
the market  value of such  securities.  As  interest  rates  rise,  the value of
fixed-income  securities will fall,  adversely  affecting the net asset value of
the Fund.

     Mortgaged-Backed  Securities. The value of mortgage-backed securities, like
that of traditional fixed-income  securities,  typically increases when interest
rates fall and decreases  when  interest  rates rise.  However,  mortgage-backed
securities are also subject to the risk of prepayment.  In a period of declining
interest  rates,  borrowers may pay what they owe on the underlying  assets more
quickly  than  anticipated,  which  will  reduce the yield to  maturity  and the
average  life of the  mortgage-backed  securities.  In  addition,  when the Fund
reinvests the proceeds of a prepayment  it will likely  receive an interest rate
lower  than the rate on the  security  that was  prepaid.  In a period of rising
interest  rates,  prepayments  may occur at a slower than  expected  rate.  As a
result, the average maturity of the Funds portfolio will increase.  The value of
long-term  securities  generally  changes  more widely in response to changes in
interest rates than short-term securities.

     Indexed and Inverse  Securities.  The Fund may invest in  securities  whose
potential return is based on the changes in particular  measurements of value or
an interest  rate (an  "index").  As an  illustration,  the Fund may invest in a
security that pays  interest and returns of principal  based on the change in an
index of  interest  rates or on the value of an index.  Interest  and  principal
payable on a security  may also be based on relative  changes  among  particular
indices.  In  addition,  the Fund  may  invest  in  securities  whose  potential
investment  return is inversely based on the change in particular  indices.  For
example,  the Fund may invest in  securities  that pay a higher rate of interest
and principal when a particular index decreases and pay a lower rate of interest
and principal when the value of the index increases. To the extent that the Fund
invests in such types of securities,  it will be subject to the risks associated
with changes in the particular indices,  which may include reduced or eliminated
interest payments and losses of invested principal.

     Certain indexed securities,  including certain inverse securities, may have
the  effect of  providing  a degree of  investment  leverage,  because  they may
increase  or  decrease  in value at a rate that is a multiple  of the changes in
applicable  indices.  As a result,  the  market  value of such  securities  will
generally be more volatile than the market 


                                       2
<PAGE>

values of fixed-rate  securities.  The Fund  believes  that indexed  securities,
including  inverse   securities,   represent   flexible   portfolio   management
instruments that may allow the Fund to seek potential investment rewards,  hedge
other portfolio  positions,  or vary the degree of portfolio leverage relatively
efficiently under different market conditions.

                     RISK FACTORS AND SPECIAL CONSIDERATIONS

Investment Restrictions

     The  Fund  has  adopted  the  following   fundamental  and  non-fundamental
restrictions  and  policies  relating  to the  investment  of its assets and its
activities.  The fundamental policies set forth below may 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 of 1940
(the  "Investment  Company  Act")  means  the  lesser  of (i) 67% of the  shares
represented  at a meeting at which more than 50% of the  outstanding  shares are
represented or (ii) more than 50% of the outstanding shares).

     Under the fundamental investment restrictions, the Fund may not:

        1. Make any investment  inconsistent with the Fund's classification as a
   diversified company under the Investment Company Act.

        2.  Invest more than 25% of its assets,  taken at market  value,  in the
   securities  of  issuers  in  any  particular   industry  (excluding  the  U.S
   Government and its agencies and instrumentalities).

        3. Make investments for the purpose of exercising control or management.

        4. 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  which
   invest in real estate or interests therein.

        5. 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.

        6. Issue  senior securities to the extent such  issuance  would  violate
   applicable law.

        7.  Borrow  money,  except  that (i) the Fund may borrow  from banks (as
   defined in the  Investment  Company Act) in amounts up to 331/3% 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.

        8.  Underwrite  securities of other issuers  except  insofar as the Fund
   technically may be deemed an underwriter under the Securities Act of 1933, as
   amended (the "Securities Act") in selling portfolio securities.

        9. 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.


                                       3
<PAGE>

     Under the non-fundamental investment restrictions, the Fund may not:

        a. Purchase  securities  of other  investment  companies,  except to the
   extent such purchases are 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.

        b. Make short sales of securities or maintain a short  position,  except
   to the extent permitted by applicable law. The Fund currently does not intend
   to engage in short sales, except short sales "against the box."

        c. Invest in securities  which cannot be readily resold because of legal
   or contractual  restrictions or which 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 total  assets  would be  invested  in such  securities.  This
   restriction  shall not apply to securities  which mature within seven days or
   securities  which the Board of Trustees of the Fund has otherwise  determined
   to be liquid pursuant to applicable law.

        d.  Notwithstanding  fundamental  investment  restriction (7) above, the
   Fund will not borrow amounts in excess of 5% of the total assets of the Fund,
   taken at market  value,  and then only from banks as a temporary  measure for
   extraordinary or emergency purposes such as the redemption of Fund shares. In
   addition,  the  Fund  will  not  purchase  securities  while  borrowings  are
   outstanding.

     Because  of the  affiliation  of  Merrill  Lynch,  Pierce,  Fenner  & Smith
Incorporated  ("Merrill  Lynch")  with the  Fund,  the Fund is  prohibited  from
engaging in certain  transactions  involving Merrill Lynch except pursuant to an
exemptive order or otherwise in compliance with the provisions of the Investment
Company  Act and the rules  and  regulations  thereunder.  Included  among  such
restricted  transactions  are (i)  purchases  from or sales to Merrill  Lynch of
securities in  transactions  in which Merrill Lynch acts as principal,  and (ii)
purchases of securities from underwriting syndicates of which Merrill Lynch is a
member.

     Mortgage-Backed  Securities.  Mortgage-backed securities are "pass-through"
securities, meaning that principal and interest payments made by the borrower on
the  underlying  mortgages  are  passed  through  to  the  Fund.  The  value  of
mortgage-backed  securities,  like that of traditional  fixed-income securities,
typically  increases  when interest rates fall and decreases when interest rates
rise. However,  mortgage-backed  securities differ from traditional fixed-income
securities because of their potential for prepayment without penalty.  The price
paid by the Fund for its mortgage-backed  securities, the yield the Fund expects
to receive from such securities and the average life of the securities are based
on a number of factors,  including  the  anticipated  rate of  prepayment of the
underlying  mortgages.  In a period of declining  interest rates,  borrowers may
prepay the underlying mortgages more quickly than anticipated,  thereby reducing
the yield to maturity  and the average life of the  mortgage-backed  securities.
Moreover,  when  the  Fund  reinvests  the  proceeds  of a  prepayment  in these
circumstances,  it will likely receive a rate of interest that is lower than the
rate on the  security  that was prepaid.  To the extent that the Fund  purchases
mortgaged-backed  securities at a premium,  mortgage  foreclosures and principal
prepayments  may result in a loss to the extent of the premium paid. If the Fund
buys such  securities at a discount,  both  scheduled  payments of principal and
unscheduled  prepayments  will  increase  current  and  total  returns  and will
accelerate the recognition of income which,  when  distributed to  shareholders,
will be  taxable  as  ordinary  income.  In a period of rising  interest  rates,
prepayments  of the  underlying  mortgages  may occur at a slower than  expected
rate,  creating  maturity  extension  risk. This particular risk may effectively
change a security that was considered short or  intermediate-term at the time of
purchase  into  a  long-term  security.  Since  long-term  securities  generally
fluctuate more widely in response to changes in interest rates than shorter-term
securities,  maturity  extension risk could increase the inherent  volatility of
the Fund.

     Indexed and Inverse-Indexed  Securities.  The Fund may invest in securities
whose potential  returns are directly  related to changes in an underlying index
or interest rate, known as indexed securities.  The return on indexed securities
will rise when the  underlying  index or  interest  rate rises and fall when the
index or interest  rate  falls.  The Fund may also  invest in  securities  whose
return is  inversely  related  to  changes  in an  interest  rate.  In  general,
inverse-indexed  securities change in value in a manner that is opposite to most
bonds -- that is, interest 


                                       4
<PAGE>

rates on these  securities  will decrease when interest  rates increase in value
and  increase  in  value  when   interest   rates   decrease.   Investments   in
inverse-indexed  securities  may  subject  the Fund to the risks of  reduced  or
eliminated  interest  payments and losses of  principal.  In  addition,  certain
indexed  securities and  inverse-indexed  securities may increase or decrease in
value at a greater rate than the  underlying  interest rate,  which  effectively
leverages  the  Fund's  investment.  As a  result,  the  market  value  of  such
securities will generally be more volatile than that of fixed rate securities.

     Lending of Portfolio  Securities.  Subject to  investment  restriction  (5)
above,  the Fund from time to time may lend  securities  from its  portfolio  to
brokers,  dealers and financial  institutions  and receive as collateral cash or
United  States  Treasury  securities  which  at all  times  while  the  loan  is
outstanding  will be maintained in amounts equal to at least 100% of the current
market value of the loaned  securities.  Any cash collateral will be invested in
short-term securities,  which will increase the current income of the Fund. Such
loans,  which will not have terms longer than 30 days, will be terminable at any
time.  The Fund  will  have the  right to  regain  record  ownership  of  loaned
securities to exercise  beneficial  rights such as voting  rights,  subscription
rights and rights of dividends,  interest or other  distributions.  The Fund may
pay  reasonable  fees to  persons  unaffiliated  with the Fund for  services  in
arranging  such loans.  In the event of a default by the borrower,  the Fund may
suffer time delays and incur costs or  possible  losses in  connection  with the
disposition of the collateral.

     Forward  Commitments.   U.S.  Government   securities  and  corporate  debt
obligations  may be purchased on a forward  commitment  basis at fixed  purchase
terms with periods of up to 45 days between the commitment and settlement dates.
The  purchase  will be recorded on the date the Fund enters into the  commitment
and the value of the security will thereafter be reflected in the calculation of
the Fund's net asset value.  The value of the security on the delivery  date may
be more or less than its purchase price. A separate  account of the Fund will be
established  with the  Custodian  consisting  of cash or liquid  high grade debt
obligations  having a market value at all times until the delivery date at least
equal to the amount of the forward commitment.  Although the Fund will generally
enter into forward  commitments  with the intention of acquiring  securities for
its portfolio,  the Fund may dispose of a commitment  prior to settlement if the
Investment  Adviser deems it appropriate  to do so. There can, of course,  be no
assurance  that the  judgments  upon which  these  techniques  are based will be
accurate or that such techniques  when applied will be effective.  The Fund will
enter into forward  commitment  arrangements  only with respect to securities in
which it may otherwise invest.

     Repurchase  Agreements.  The Fund may  invest  in  securities  pursuant  to
repurchase agreements.  Under such agreements,  the seller agrees, upon entering
into the contract, to repurchase the security at a mutually agreed-upon time and
price,  thereby  determining  the yield during the term of the  agreement.  This
results in a fixed rate of return insulated from market fluctuations during such
period.  Such  agreements  usually cover short periods,  such as under one week.
Repurchase  agreements  may  be  construed  to be  collateralized  loans  by the
purchaser to the seller secured by the securities  transferred to the purchaser.
The Fund will require the seller to provide additional  collateral if the market
value of the securities  falls below the repurchase price at any time during the
term of the repurchase agreement.  In the event of default by the seller under a
repurchase  agreement  construed to be a  collateralized  loan,  the  underlying
securities  are not  owned by the Fund but only  constitute  collateral  for the
seller's obligation to pay the repurchase price. Therefore,  the Fund may suffer
time  delays  and  incur  costs  or  possible  losses  in  connection  with  the
disposition of the collateral.  Instead of the contractual fixed rate of return,
the rate of return to the Fund will be dependent upon  intervening  fluctuations
of the market value of such  security and the accrued  interest on the security.
In such  event,  the Fund would  have  rights  against  the seller for breach of
contract with respect to any losses arising from market  fluctuations  following
the  failure  of the  seller to  perform.  From time to time,  the Fund also may
invest  in  securities  pursuant  to  purchase  and sale  contracts.  While  the
substance of purchase and sale  contracts is similar to  repurchase  agreements,
because  of the  different  treatment  with  respect  to  accrued  interest  and
additional collateral,  management believes that purchase and sale contracts are
not  repurchase  agreements  as  such  term is  understood  in the  banking  and
brokerage  community.  As a matter of operating policy,  the Fund will not enter
into  repurchase  agreements  or purchase and sale  contracts  with greater than
seven days to maturity if, at the time of such investment,  more than 10% of the
total assets of the Fund would be so invested.

                 MANAGEMENT AND INVESTMENT ADVISORY ARRANGEMENTS

     The  Investment  Adviser  to the Fund is MLAM,  an  indirect  wholly  owned
subsidiary  of Merrill  Lynch & Co.,  Inc.  The  Investment  Adviser acts as the
investment adviser for the Fund and provides the Fund with management  services.
The Investment Adviser (the general partner of which is Princeton Services Inc.,
a wholly owned  subsidiary of ML & Co.) has its  principal  place of business at
800 Scudders Mill Road, Plainsboro,  New Jersey 08536 (mailing address: P.O. Box
9011,  Princeton,  New Jersey  08543-9011).  ML & Co. has its principal place of
business at 250 Vesey Street,  New York, New York 10281. The Investment  Adviser
or its affiliate,  Fund Asset Management,  L.P. ("FAM"),  acts as the investment
adviser  for more  than 140  registered  investment  companies.  The  Investment
Adviser also offers  portfolio  management  and portfolio  analysis  services to
individual and institutional  accounts.  As of December 31, 1998, the Investment
Adviser  and FAM had a total of $501  billion in  investment  company  and other
portfolio assets under management,  including  accounts of certain affiliates of
the Investment Adviser.

     The Investment Adviser is a limited partnership,  the partners of which are
ML  &  Co.  and  Princeton  Services.  ML  &  Co.  and  Princeton  Services  are
"controlling  persons" of the Investment Adviser 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  Limited  (MLAM  U.K.'s  parent),   a  subsidiary  of  ML
International  Holdings,  a subsidiary  of Merrill  Lynch  International,  Inc.,
subsidiary of ML & Co.

     The  Investment  Adviser has entered  into a  sub-advisory  agreement  (the
"Sub-Advisory  Agreement") with MLAM U.K., an indirect,  wholly owned subsidiary
of ML & Co. and an affiliate of the  Investment  Adviser,  pursuant to which the
Investment  Adviser  pays  MLAM U.K.  a fee for  providing  investment  advisory
services to the  Investment  Adviser with respect to the Fund in an amount to be
determined  from time to time by the Investment  Adviser and MLAM U.K. but in no
event in excess of the amount that the Investment  Adviser actually receives for
providing  services to the Fund pursuant to the Investment  Advisory  Agreement.
The address of the  sub-adviser  is Milton Gate,  1 Moor Lane,  London EC2Y 9HA,
England.

     Pursuant to the terms of the Investment Advisory Agreement,  the Investment
Adviser,  subject to the general  supervision of the Trustees of the Fund and in
conformance with the stated policies of the Fund, renders investment supervisory
and   administrative   services  to  the  Fund.  In  this  regard,   it  is  the
responsibility  of the Investment  Adviser to make investment  decisions for the
Fund and to place the purchase and sale orders for the portfolio transactions of
the Fund.  In addition  the  Investment  Adviser  performs,  or  supervises  the
performance of,  administrative  services in connection with the Fund, including
(i)  supervision  of all aspects of the Fund's  administration  and  operations,
including  processing  services  related to the purchase and  redemption of Fund
shares, the general handling of shareholder relations, and portfolio management;
(ii) providing the Fund, at the Investment Adviser's expense,  with the services
of persons competent to perform such  administrative  and clerical  functions as
are  necessary in order to provide  effective  administration  of the Fund;  and
(iii)  providing the Fund, at the Investment  Adviser's  expense,  with adequate
office space and related  services.  The Investment  Adviser may arrange for the
provision  of these  administrative  services  and  functions by MLFD or another
affiliate of ML & Co.

     The Investment  Advisory Agreement  obligates the Investment Adviser 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  compensation of all Trustees of the Fund who
are affiliated persons of ML & Co. or any of its subsidiaries. The Fund pays all
other  expenses  incurred in the  operation of the Fund  including,  among other
things,  taxes,  expenses  for legal and  auditing  services,  costs of printing
proxies, stock certificates, shareholder reports, prospectuses and statements of
additional  information (except to the extent paid by the Distributor),  charges
of the  custodian  and the transfer  agent,  expenses of  redemption  of shares,
Securities and Exchange  Commission  fees,  expenses of  registering  the shares
under  Federal and state  securities  laws,  fees and  expenses of  unaffiliated
trustees,  accounting and pricing costs (including the daily  calculation of net
asset  value),  insurance,  interest,  brokerage  costs,  litigation  and  other
extraordinary or non-recurring  expenses, and other expenses properly payable by
the  Fund.  Accounting  services  are  provided  for the Fund by the  Investment
Adviser,  and the  Fund  reimburses  the  Investment  Adviser  for its  costs in
connection with those services. MLFD pays certain of the expenses of the Fund in
connection  with the continuous  offering of Fund 


                                       8
<PAGE>

shares.  Certain distribution  expenses will be financed by the Fund pursuant to
the  Distribution  Plans in  compliance  with Rule  12b-1  under the  Investment
Company Act of 1940. See "Distribution Plans."

     As  compensation  for the services  rendered under the Investment  Advisory
Agreement,  the Fund pays the Investment  Adviser a fee, payable monthly,  at an
annual  rate of 0.40% of the Fund's  average  daily net  assets.  MLAM  received
$150,322 (based on average daily net assets of  approximately  $37.7 million) in
investment  advisory  fees from the Fund  during  the Fund's  fiscal  year ended
October  31,  1998,  of  which  $122,202  was  voluntarily   waived.  MLAM  also
voluntarily  reimbursed the Fund for additional expenses of $1,011. For the same
period,  the ratio of total expenses to average net assets was 1.09% for Class A
shares, 1.54% for Class B shares, 1.26% for Class C shares and 1.22% for Class D
shares.  Accounting  services  are  provided  to the Fund by MLAM,  and the Fund
reimburses MLAM for its costs in connection  with such services.  For the fiscal
years ended October 31, 1998,  1997 and 1996,  the amount of such  reimbursement
was $37,878, $231,551 and $152,873, respectively.

Duration and Termination

     The Investment  Advisory Agreement is effective as of October 31, 1986 and,
unless earlier  terminated as described below, will continue in effect from year
to year if  approved  annually  (a) by the Board of Trustees of the Fund or by a
majority  of the  outstanding  shares of the Fund,  and (b) by a majority of the
trustees who are not parties to that contract or interested  persons (as defined
in the  Investment  Company  Act of  1940)  of any such  party.  The  Investment
Advisory  Agreement  will  terminate  automatically  upon its  assignment and is
terminable at any time without  penalty by the trustees of the Fund or by a vote
of a majority of the Fund's  outstanding  shares (as defined  under  "Investment
Restrictions" herein) or by the Investment Adviser on 60 days' written notice to
the other  party.  The  Investment  Advisory  Agreement  was last renewed by the
Fund's Board of Trustees on September 8, 1998.

     The investment  advisory services of the Investment Adviser to the Fund are
not  exclusive  under the terms of the  Investment  Advisory  Agreement  and the
Investment Adviser is also free to, and does, render such services to others.

     Transfer  Agency  Serivices.  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.

Code of Ethics

     The Board of Trustees  of the Fund has adopted a Code of Ethics  under Rule
17j-1 of the Investment Company Act of 1940 (the "Investment Company Act") which
incorporates  the  Code of  Ethics  of the  Investment  Adviser  (together,  the
"Codes").  The Codes significantly restrict the personal investing activities of
all  employees  of the  Investment  Adviser  and,  as  described  below,  impose
additional, more onerous, restrictions on fund investment personnel.

     The Codes require that all employees of the Investment Adviser preclear any
personal  securities  investment  (with limited  exceptions,  such as government
securities). The preclearance requirement and associated procedures are designed
to identify any substantive prohibition or limitation applicable to the proposed
investment.  The  substantive  restrictions  applicable  to all employees of the
Investment  Adviser include a ban on acquiring any securities in a "hot" initial
public  offering  and a  prohibition  from  profiting on  short-term  trading 


                                       9
<PAGE>

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 Investment  Adviser.  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  issues four  classes of shares  under the  Merrill  Lynch  Select
Pricing(SM)  System:  Class A and Class D shares are sold to investors  choosing
the initial sales charge alternatives and Class B and Class C shares are sold to
investors choosing the deferred sales charge  alternatives.  Each Class A, Class
B,  Class C and  Class D share  represents  an  identical  interest  in the same
portfolio of  investments  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 and the 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  deferred  sales
charges  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,  will be imposed  directly  against  those  classes  and not against all
assets of the Fund and, accordingly,  such charges will 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  will be
calculated  in the same  manner  at the same  time and will  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.  Class B, Class C and Class D shares of the Fund each have exclusive
voting  rights with  respect to the Rule 12b-1  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).  See
"Distribution  Plans" below. Each class has different exchange  privileges.  See
"Shareholder  Services -- Exchange Privilege." Class C shares are available only
through the Exchange privilege.

     Investors  should  understand  that the purpose and function of the initial
sales  charges  with respect to Class A and Class D shares are the same as those
of the contingent  deferred  sales charge  ("CDSC") and  distribution  fees with
respect to 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.  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.

Alternative Sales Arrangements

     The alternative sales  arrangements  available for the Fund's shares permit
each  investor  to choose  the method of  purchasing  shares  that the  investor
believes is most beneficial given the amount of the purchase, the length of time
the  investor  expects  to hold his  shares  and other  relevant  circumstances.
Investors  should determine  whether under their particular  circumstances it is
more advantageous to incur an initial sales charge and not be subject to ongoing
charges,  as  discussed  below,  or to have the entire  initial  purchase  price
invested in the Fund with the  investment  thereafter  being  subject to ongoing
charges.

     The  Merrill  Lynch  Select  PricingSM  System  is  used  by  more  than 50
registered investment companies advised by MLAM or its affiliate, the Investment
Adviser.  Funds advised by MLAM or the  Investment  Adviser that use the Merrill
Lynch Select PricingSM System are referred to herein as "Select Pricing Funds.

     The  Fund  has  entered  into   separate   distribution   agreements   (the
"Distribution   Agreements")   with  the  Distributor  in  connection  with  the
continuous  offering  of each  class  of  shares.  The  Distribution  Agreements


                                       10
<PAGE>

obligate the Distributor to pay certain expenses in connection 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 Investment  Advisory  Agreement
described above.

     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 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  choosing the initial sales charge  alternatives 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.
Sales charges for purchases of Class A and Class D shares of the Fund,  computed
as indicated in the Prospectus, are reduced on larger purchases. The Distributor
may reallow discounts to selected securities 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  within the meaning of the Securities Act of 1933. The
proceeds  from  the  account   maintenance  fees  are  used  to  compensate  the
Distributor  and Merrill  Lynch  (pursuant  to a  sub-agreement)  for  providing
continuing  account  maintenance  activities.  The  Distributor  will retain the
entire sales charge on orders placed directly with it.

     A reduced  sales charge is available for any purchase of Class A or Class D
shares of the Fund in excess of $100,000.  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 spouse and
their children under the age of 21 years purchasing  shares for his 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  (including  a
pension,  profit-sharing  or other employee  benefit trust created pursuant to a
plan qualified under Section 401 of the Code) 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 that 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  by  employees  or by  employers  on  behalf of
employees,  by means of a payroll deduction plan or otherwise,  of shares of the
Fund.  Purchases by such a 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.

     For the fiscal  year ended  October  31,  1998,  there were no gross  sales
charges for the sale of Class A shares.  For the fiscal  year ended  October 31,
1998,  the  Distributor  received no CDSC  proceeds  with respect to  redemption
within one year after purchase of Class A shares purchased subject to an initial
sales charge waiver.


                                       11
<PAGE>

     For the fiscal year ended October 31, 1998, the gross sales charges for the
sale of  Class  D  shares  were  $6,509,  of  which  $570  was  received  by the
Distributor and $5,939 was received by Merrill Lynch.  For the fiscal year ended
October 31, 1998,  the  Distributor  received no CDSC  proceeds  with respect to
redemption within one year after purchase of Class D shares purchased subject to
an initial sales charge waiver.

     Eligible  Class A Investors.  Class A shares are offered to a limited group
of  investors  and also will be  issued  upon  reinvestment  of  dividends  from
outstanding  Class A shares.  Investors  that  currently own Class A shares in a
shareholder  account,  including  participants in the Merrill Lynch  BlueprintSM
Program,  are entitled to purchase additional Class A shares of the Fund in that
account.  Certain  employer  sponsored  retirement or savings  plans,  including
eligible  401(k)  plans,  may  purchase  Class A shares of the Fund 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  provided  that the  program  has $3  million  or more  initially
invested in MLAM-advised  mutual funds. Also eligible to purchase Class A shares
at net asset value are  participants in certain  investment  programs  including
TMA(Service  Mark) 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 will be 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 or Class D shares of the Fund if certain  conditions  set
forth below under "Reduced  Initial Sales Charges -- Closed-End  Fund Investment
Option" are met.

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. Class A and Class D sales charges also may be reduced
under a Right of  Accumulation  and a Letter of  Intention.  Class A shares  are
offered at net asset value to certain  eligible  Class A investors  as set forth
above under "Eligible Class A Investors." See "Shareholder Services -- Fee-Based
Programs."

     Right of Accumulation. Reduced sales charges are applicable through a right
of accumulation under which eligible investors are permitted to purchase Class A
or Class D shares of the Fund  subject to initial  sales  charge at the 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 Fund. 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,  and
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  Intention.  Reduced  sales  charges are  applicable to purchases
through any dealer aggregating $100,000 or more of Class A shares of the Fund or
any other Select Pricing Funds made within a 13-month  period  starting with the
first  purchase  pursuant to a Letter of Intention  in the form  provided by the
Distributor.  The Letter of  Intention  is  available  only to  investors  whose
accounts are maintained at the Fund's Transfer Agent. The Letter of Intention is
not a binding  obligation  to purchase  any amount of Class A or Class D shares,
but its execution will result in the purchaser's  paying a lower sales charge at
the appropriate quantity purchase level. A purchase not originally made pursuant
to a Letter of  Intention  may be included  under a subsequent  Letter  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 or of other  MLAM-advised  mutual funds  presently  held, at cost or
maximum offering price (whichever is higher),  on the date of the first purchase
under the Letter of Intention, may be included as a credit toward the completion
of such Letter. The reduced sales charge applicable to the amount covered by the
Letter of Intention will be applied only to new  purchases.  If the total amount
of shares


                                       12
<PAGE>

purchased  does not equal the  amount  stated in the  Letter of  Intention,  the
investor will be notified and must pay, within 20 days of the expiration of such
Letter,  the difference between the sales charge on Class A or Class D shares of
the Fund  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
five percent of the intended  amount will be held in escrow  during the 13-month
period  (while  remaining  registered in the name of the  purchaser).  The first
purchase under the Letter of Intention must be five percent of the dollar amount
of such Letter.  If during the term of such Letter,  a purchase brings the total
amount  invested to an amount  equal to or in excess of the amount  indicated in
the Letter,  the  purchaser  will be entitled on that  purchase  and  subsequent
purchases to the reduced  percentage sales charge which would be applicable to a
single purchase equal to the total dollar value of the Class A or Class D shares
of the Fund then  being  purchased  under  such  Letter,  but  there  will be no
retroactive  reduction of the sales charges 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 Intention  will be deducted from the
total  purchases made under such Letter.  An exchange from a MLAM-advised  money
market  fund  into the Fund  that  creates  a sales  charge  will  count  toward
completing a new or existing Letter of Intention in the Fund.

     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 AccessSM Accounts available through authorized  employers.  The initial
minimum for such  accounts is $500,  except that the initial  minimum for shares
purchased for such accounts pursuant to the Automatic Investment Program is $50.

     TMA(SM)  Managed  Trusts.  Class A shares are  offered  to TMA(SM)  Managed
Trusts to which  Merrill  Lynch Trust  Company  provides  discretionary  trustee
services at net asset value.

     Purchase Privileges of Certain Persons. Trustees of the Fund, directors and
trustees of other MLAM-advised  mutual 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  or  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.

     The  shares of the Fund in  existence  prior to its  reorganization  at the
close of business on February 14, 1997 have been reclassified as Class D shares.
Although  purchasers of Class D shares generally will be subject to a 1% initial
sales charge,  those  shareholders  of the Fund who have held shares of the Fund
since prior to its reorganization at the close of business on February 14, 1997,
will  not  be  subject  to  any  sales  charge  with  respect  to  either  their
reclassified  Class D shares or any Class D shares that they may purchase in the
future.

     Closed-End  Fund  Investment  Option.  Class A shares of the Fund and other
MLAM-advised  mutual funds  ("Eligible Class A Shares") are offered at net asset
value to  shareholders  of certain  closed-end  funds advised by the  Investment
Adviser or MLAM who purchased such  closed-end  fund shares prior to October 21,
1994 (the date the Merrill Lynch Select PricingSM  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 of the Fund.  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  MLAM-advised  mutual  funds  ("Eligible  Class D
Shares").  In  order  to  exercise  this  investment  option,   closed-end  fund
shareholders  must (i) sell their  closed-end  fund shares through Merrill Lynch
and reinvest the proceeds  immediately in the Eligible Class A or Class D Shares
of the Fund,  (ii)  either have  acquired  the shares in the  closed-end  fund's
initial public offering or through  reinvestment  of dividends  earned on shares
purchased in such offering,  (iii) have maintained  their closed-end fund shares
continuously  in a Merrill  Lynch  account,  and (iv) purchase a minimum of $250
worth of Fund shares.  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,  


                                       13
<PAGE>

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 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.

     Class D shares  of the Fund are  offered  at the net asset  value,  without
sales  charge,  to an investor  who has a business  relationship  with a Merrill
Lynch  Financial  Consultant  and who 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 he or she will
purchase  Class D shares of the Fund with  proceeds  from a  redemption  of such
shares of other  mutual funds and that such shares have been  outstanding  for a
period of no less than six months.  Second, such purchase of Class D shares must
be made within 60 days after the redemption and the proceeds from the redemption
must have 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
sales  charge,  to an investor  who has a business  relationship  with a Merrill
Lynch Financial  Consultant and who 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 such fund was
subject to a sales charge either at the time of purchase or on a deferred basis.
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  sales
charge,  to an  investor  who  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 with  proceeds  from a redemption  of shares of a
mutual fund that was sponsored by the financial  consultant's  previous firm and
imposed a sales  charge  either at the time of purchase or on a deferred  basis.
Second,  the investor also 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.

     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 investors.

     Acquisition of Certain Investment  Companies.  The public offering price of
Class D shares of the Fund 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 in appropriate cases be adjusted to reduce possible adverse tax consequences
to the Fund  which  might  result  from an  acquisition  of  assets  having  net
unrealized  appreciation  which  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  which (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 charge are due
to the nature of the  investors  and/or the reduced  sales  efforts that will be
needed in obtaining such investments.

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  MLAM-advised  mutual  funds.  Class C shares,
however, are available only through the Exchange Privilege.

     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.

     Class B and Class C shares are sold without an initial sales charge so that
the Fund will  receive  the full  amount  of the  investor's  purchase  payment.
Merrill  Lynch  compensates  its Financial  Consultants  for selling Class B and
Class C shares at the time of  purchase  from its own funds.  See  "Distribution
Plans."  Both  Class B and Class C shares  are  subject  to an  ongoing  account
maintenance fee and distribution fees; however,  the ongoing account maintenance
fee and  distribution  fee potentially may be offset to the extent any return is
realized  on the  additional  funds  initially  invested  in  Class B or Class C
shares.

     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 dealers' 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.  Approximately  ten years after issuance,  Class B shares will
convert  automatically  into  Class D shares,  which are  subject  to an account
maintenance  fee but no  distribution  fee;  Class B  shares  of  certain  other
MLAM-advised  mutual funds into which exchanges may be made convert into Class D
shares  automatically  after approximately eight years. If Class B shares of the
Fund are exchanged for Class B shares of another  MLAM-advised  mutual fund, 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 onto the
holding period for the shares acquired.

     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.  The proceeds  from the ongoing
account  maintenance  fee are used to  compensate  Merrill  Lynch for  providing
continuing  account  maintenance  activities.  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.

Contingent Deferred Sales Charges  --  Class B Shares.

     Class B shares that are redeemed within one year of purchase may be subject
to a CDSC at the rates set forth  below  charged as a  percentage  of the dollar
amount  subject  thereto.  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.

     The following table sets forth the rates of the CDSC on Class B shares:

                                                   Contingent Deferred Sales
                                                    Charge as a Percentage
                                                       of Dollar Amount
        Year Since Purchase Payment Made               Subject to Charge
        --------------------------------           -------------------------
        0-1 .....................................             1.0%
        Thereafter ..............................            None

     In  determining  whether  a  CDSC  is  applicable  to  a  redemption,   the
calculation will be determined in the manner that results in the lowest possible
applicable rate being charged. Therefore, it will be assumed that the redemption
is 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 CDSC 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.


                                       15
<PAGE>

     To provide an example,  assume an investor  purchased 100 Class B shares at
$10 per share (at a cost of $1,000) and in the eighth month 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 first  redemption of 50 shares  (proceeds of $600), 10 shares
will not be subject to charge because of dividend reinvestment.  With respect to
the  remaining 40 shares,  the CDSC is applied only to the original  cost of $10
per share and not to the increase in net asset value of $2 per share. Therefore,
$400 of the $600 redemption proceeds will be charged to a CDSC at a rate of 1.0%
(the applicable rate in the first 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  the death or  disability  (as
defined in the Code) of a shareholder (including one who owns the Class B shares
as a joint tenant with his or her spouse)  provided the  redemption is requested
within one year of death or initial determination of disability. The CDSC may be
waived on redemption of shares by certain  eligible  401(a) and eligible  401(k)
plans.  The CDSC is also waived for any Class B shares which are purchased by an
eligible  401(k) or  eligible  401(a)  plan and are  rolled  over into a Merrill
Lynch,  Pierce,  Fenner & Smith  Incorporated  or Merrill  Lynch  Trust  Company
custodied  IRA and held in such  account at the time of  redemption  and for any
Class B shares that were  acquired and held at the time of the  redemption in an
Employee AccessSM Account available through employers  providing eligible 401(k)
plans. The Class B CDSC also is 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  Class B CDSC is also  waived  for any  Class B
shares that are purchased within  qualifying  Employee  AccessSM  Accounts.  The
terms of the CDSC may be waived or its terms  may be  modified  for  redemptions
made in connection with fund  participation in certain fee-based  programs.  The
Class B CDSC may also be waived in connection with involuntary termination of an
account in which Fund  shares are held or for  withdrawals  through  the Merrill
Lynch  Systematic   Withdrawal  Plan.  See  "Shareholder   Services   -Fee-Based
Programs," and "Systematic Withdrawal Plan."

Contingent Deferred Sales Charges -- Class C Shares.

     Class C shares  which  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.  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.  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."

     The deferred  sales charge  relating to Class B and C shares may be reduced
or waived for withdrawal through the Merrill Lynch Systematic Withdrawal Plan of
up to 10% per year of the account value at the time the plan is established  and
in connection  with  involuntary  termination of an account in which Fund shares
are held.

*  Additional  Class B CDSCs  payable  to the  Distributor  with  respect to the
   fiscal  years  ended  October  31,  1997 and 1998 may  have  been  waived  or
   converted to a  contingent  obligation  in  connection  with a  shareholder's
   participation in certain fee-based programs.

     For the fiscal  years  ended  October 31,  1997 and 1998,  the  Distributor
received no CDSCs with respect to redemptions of Class C shares.

     In  determining  whether a Class C CDSC is  applicable to  redemption,  the
calculation will be determined in the manner that results in the lowest possible
rate being charged.  Therefore,  it will be assumed that the 


                                       16
<PAGE>

redemption is first of shares held 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.

     Conversion  of Class B Shares to Class D Shares.  After  approximately  ten
years (the "Conversion Period"),  Class B shares will be converted automatically
into  Class  D  shares.  Class  D  shares  are  subject  to an  ongoing  account
maintenance fee at an annual rate of 0.10% of average daily 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 values
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 into 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 a 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.

     Class B shareholders holding certificates must deliver such certificates to
the Transfer Agent at least one week prior to the Conversion  Date applicable to
those  shares.  Shares  evidenced by  certificates  that are not received by the
Transfer Agent at least one week prior to the Conversion  Date will be converted
into  Class  D  shares  on  the  next  scheduled   Conversion  Date  after  such
certificates are delivered.

     In general, Class B shares of MLAM-advised equity mutual funds will convert
approximately  eight  years  after  initial  purchase,  and  Class B  shares  of
MLAM-advised  taxable and  tax-exempt  fixed  income  mutual  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 onto the
holding period for the shares acquired.

     The Conversion  Period is modified for  shareholders  who purchased Class B
shares through certain retirement plans which qualified for a waiver of the CDSC
normally  imposed on purchases of Class B shares  ("Class B Retirement  Plans").
When the first  share of any  MLAM-advised  mutual fund  purchased  by a Class B
Retirement  Plan has been held for ten years (i.e.,  ten years from the date the
relationship  between  MLAM-advised mutual funds and the Class B Retirement Plan
was  established),  all Class B shares of all MLAM-advised  mutual funds held in
that  Class B  Retirement  Plan  will be  converted  into  Class D shares of the
appropriate funds.  Subsequent to such conversion,  that Class B Retirement Plan
will be sold  Class D shares of the  appropriate  funds at net  asset  value per
share.

     In the event that all Class B shares held in a single account are converted
to Class D shares on a Conversion  Date,  shares  representing  reinvestment  of
declared but unpaid  dividends on those Class B shares also will be converted to
Class D shares; otherwise, only Class B shares purchased through reinvestment of
dividends paid will convert to Class D shares on the Conversion Date.

     The Conversion  Period may also be modified for  retirement  plan investors
who participate in certain  fee-based  programs.  See  "Shareholder  Services --
Fee-Based Programs."

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  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
MLAM-advised mutual fund. Minimum


                                       17
<PAGE>

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.

Distribution Plans

     Reference  is made to "Fees and  Expenses"  in the  Prospectus  for certain
information  with  respect to the  separate  distribution  plans of the Fund 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 or payable by the Fund to the  Distributor  with
respect to such classes.

     The Distribution Plans for Class B, Class C and Class D shares each provide
that the Fund pays the  Distributor an account  maintenance  fee relating to the
shares  of the  relevant  class of the  Fund's  shares,  accrued  daily and paid
monthly, at the annual rate of 0.25% of average daily net assets of the relevant
class  for Class B and Class C shares,  and 0.10% of  average  daily net  assets
attributable to the relevant class for Class D shares in order to compensate the
Distributor and Merrill Lynch (pursuant to a  sub-agreement)  in connection with
account maintenance activities.

     The Distribution Plans for Class B and Class C shares each provide 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 0.25% of
average  daily net assets  attributable  to the  relevant  class for Class B and
Class C  shares,  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.  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. In this regard, the purpose and function
of the  ongoing  distribution  fees  and the  CDSC  are the same as those of the
initial  sales charge with respect to the Class A and Class D shares of the Fund
in that the CDSC and ongoing  distribution fees provide for the financing of the
distribution of the Fund's Class B and Class C shares.

     For the fiscal year ended October 31, 1998,  the Fund paid the  Distributor
$38,868  pursuant to the Class B  Distribution  Plan (based on average daily net
assets subject to such Class B Distribution Plan of approximately $7.8 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 October 31, 1998, the Fund paid the Distributor $1,938
pursuant to the Class C  Distribution  Plan  (based on average  daily net assets
subject to such Class C Distribution Plan of approximately $0.8 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  October  31,  1998,  the Fund paid the  Distributor
$28,168  pursuant to the Class D  Distribution  Plan (based on average daily net
assets  subject  to  such  Class D  Distribution  Plan  of  approximately  $28.2
million),  all of  which  was  paid  to  Merrill  Lynch  for  providing  account
maintenance activities in connection with the Class D shares.

     The payments  under the  Distribution  Plans are based on a  percentage  of
average daily net assets  attributable to the relevant 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  Trustees  for their  consideration  in  connection  with their
deliberations as to the continuance of the Distribution  Plans. This information
is to be presented 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 CDSC and certain  other  related  revenues,  and
expenses consist of financial consultant expenses,  advertising, sales promotion
and marketing  expenses,  corporate overhead and interest expense. On the direct
expense and  revenue/cash  basis,  revenues  consist of the account  maintenance
fees,  distribution  fees and the CDSC and the  expenses  consist  of  financial
consultation compensation.


                                       18
<PAGE>

     Direct  cash  revenues  attributable  to Class B shares for the period from
February 18, 1997  (commencement  of  operations)  to October 31, 1998  exceeded
direct  expenses  for such period by $28,627  (representing  .072% of net assets
attributable to Class B shares at that date.  Direct cash revenues  attributable
to Class C shares  for the  period  from  February  18,  1997  (commencement  of
operations)  to October 31, 1998  exceeded  direct  expenses  for such period by
$1,594  (representing .034% of net assets attributable to Class C shares at that
date).  Direct cash revenues  attributable to Class D shares for the period from
November 11, 1996 to October 31, 1998 exceeded  direct  expenses for such period
by $690,841  (representing 2.00% of net assets attributable to Class D shares at
that date).

     The Fund has no obligation  with respect to  distributions  and/or  account
maintenance-related  expenses  incurred by the  Distributor and Merrill Lynch in
connection  with the  Class  B,  Class C and  Class D  shares,  and  there is no
assurance that the Board of Trustees of the Fund will approve the continuance of
the Distribution Plans from year to year.  However,  the Distributor  intends to
seek annual  continuation  of the  Distribution  Plans.  In their  review of the
Distribution  Plans,  the  Trustees  will be  asked to take  into  consideration
expenses incurred in connection with the account maintenance and/or distribution
of each class of shares  separately.  The  initial  sales  charges,  the account
maintenance  fee, the distribution fee and/or the CDSCs received with respect to
one class will not be used to  subsidize  the sale of shares of  another  class.
Payments  of  the  distribution  fee on  Class  B  shares  will  terminate  upon
conversion of those Class B shares into Class D shares.

     Payments  of the account  maintenance  fees  and/or  distribution  fees are
subject to the provisions of Rule 12b-1 under the Investment  Company Act. Among
other things, each Distribution Plan provides that the Distributor shall provide
and the  Trustees  shall review  quarterly  reports of the  disbursement  of the
account  maintenance fees and/or  distribution fees paid to the Distributor.  In
their  consideration of each  Distribution  Plan, the Trustees must consider all
factors  they deem  relevant,  including  information  as to the benefits of the
Distribution  Plan to the  Fund and its  related  class  of  shareholders.  Each
Distribution  Plan  further  provides  that,  so long as the  Distribution  Plan
remains  in  effect,  the  selection  and  nomination  of  Trustees  who are not
"interested  persons" of the Fund, as defined in the Investment Company Act (the
"Independent Trustees"), shall be committed to the discretion of the Independent
Trustees then in office.  In approving each Distribution Plan in accordance with
Rule  12b-1,  the  Independent  Trustees  concluded  that  there  is  reasonable
likelihood  that such  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 Independent Trustees or by the
vote of the holders of a majority  of the  outstanding  related  class of voting
securities.  A  Distribution  Plan cannot be amended to increase  materially the
amount to be spent  without the approval of the related  class of  shareholders,
and all material amendments are required to be approved by the vote of Trustees,
including a majority of the Independent  Trustees who have no direct or indirect
financial interest in such Distribution Plan, cast in person at a meeting called
for that purpose.  Rule 12b-1 further  requires that the Fund preserve copies of
each Distribution Plan and any report made pursuant to such plan for a period of
not less than six years from the date of such  Distribution Plan or such report,
the first two years in an easily accessible place.

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 Fund's distribution
fee and the CDSC  borne by the  Class B and Class C shares  but not the  account
maintenance  fees.  The maximum sales charge rule is applied  separately by each
class.  As  applicable  to the Fund,  the maximum  sales  charge rule limits the
aggregate of distribution fee payments and CDSCs payable to the sum of (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  reinvestment
and exchanges)  and (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 the  eligible  gross  sales.  Consequently,  the
maximum  amount  payable  to the  Distributor  (referred  to as  the  "voluntary
maximum") in  connection  with Class B shares is 6.75% of eligible  gross sales.
The  Distributor  retains the right to stop waiving the  interest  charge 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, 


                                       19
<PAGE>

the Fund will  continue to make  payments of the account  maintenance  fees.  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 table below sets forth comparative  information for the period February
18, 1997  (commencement  of Class B operations) to October 31, 1998 with respect
to the Class B shares of the Fund,  indicating  allowable  payments  that can be
made under the NASD maximum  sales charge rule and the  Distributor's  voluntary
maximum.  No information is presented for the Class C shares of the Fund because
Class C shares are not  available  for purchase but will be issued only pursuant
to the  Exchange  Privilege  to holders of Class C shares of other  MLAM-advised
mutual  funds who elect to  exchange  Class C shares of such other  MLAM-advised
mutual funds for Class C shares of the Fund.

     ("Summit")  which are not  reflected  in Eligible  Gross  Sales.  Shares of
     Summit can only be purchased by exchange  from another fund (the  "redeemed
     fund").  Upon such an exchange,  the maximum allowable sales charge payment
     to the  redeemed  fund is  reduced  in  accordance  with the  amount of the
     redemption. This amount is then added to the maximum allowable sales charge
     payment  with  respect  to Summit.  Upon an  exchange  out of  Summit,  the

     sales  charge  payment to Summit and added to the maximum  allowable  sales
     charge payment to the fund into which the exchange is made.

     shares prior to the expiration of the  applicable  CDSC period and invested
     the proceeds,  without  imposition of a sales charge,  in Class A shares in
     conjunction with the shareholder's  participation in the Merrill Lynch Fund
     Adviser  (Merrill  Lynch MFASM)  Program (the "MFA  Program").  The CDSC is
     booked as a contingent  obligation that may be payable when the shareholder
     terminates participation in the MFA Program.
(5)  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  or the NASD
     maximum.

                              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 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.

     The right to redeem  shares  or to  receive  payment  with  respect  to any
redemption may only be suspended for any period during which trading on the NYSE
is restricted as determined by the  Commission or such Exchange 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.


                                       20
<PAGE>

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 time 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  will  normally  accept  orders  to  repurchase  shares by wire or
telephone from dealers for their  customers at the net asset value next computed
after  receipt  of the  order  by the  dealer,  provided  that the  request  for
repurchase is received by the dealer fifteen  minutes prior to the regular close
of  business  on the NYSE on the day  received  and is received by the Fund from
such  dealer not later than 30 minutes  after the close of  business on the NYSE
(generally  4:00  p.m.,  Eastern  time),  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 (generally 4:00 p.m., Eastern
time), 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 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 Fund's 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.  A shareholder whose order
for repurchase is rejected by the Fund, however,  may redeem shares as set forth
above.

     For  shareholders  submitting  their shares for  repurchase  through listed
securities  dealers,  payment for fractional shares will be made by the Transfer
Agent  directly to the  shareholder  and payment for full shares will be made by
the   securities   dealer  within  seven  days  of  the  proper  tender  of  the
certificates,  if any, and stock power or letter requesting redemption,  in each
instance with signatures guaranteed as noted in the Prospectus.

Reinstatement Privilege

     Shareholders  who  have  redeemed  Class  A or  Class D  shares,  including
redemption  through  repurchase by the Fund, have a privilege to reinstate their
accounts by purchasing Class A or Class D shares, as the case may be, at the net
asset  value of such  shares  without  a sales  charge up to the  dollar  amount
redeemed.  The reinstatement  privilege may 


                                       21
<PAGE>

be exercised as follows.  A notice to exercise this privilege along with a check
for the amount to be reinstated must be received by the Transfer Agent within 30
days after the date the  request for  redemption  was  accepted by the  Transfer
Agent or the  Distributor.  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 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.

     If a shareholder disposes of shares within 90 days of their acquisition and
subsequently  reacquires  shares  of the  Fund  pursuant  to  the  reinstatement
privilege,  then the shareholder's tax basis in those shares disposed of will be
reduced to the extent the load  charge  paid to the Fund upon the  shareholder's
initial  purchase  reduces  any load  charge  such  shareholder  would have been
required to pay on the subsequent  acquisition  in absence of the  reinstatement
privilege.  Instead,  such load charge will be treated as an amount paid for the
subsequently acquired shares and will be included in the shareholder's tax basis
for such shares.

                                PRICING OF SHARES

Determination of New Asset Value

     Reference  is made to "How  Shares are Priced" in the  Prospectus.  The net
asset  value  of the  shares  of the  Fund  is  determined  once  daily  by MLAM
immediately  after the declaration of dividends as of 15 minutes after the close
of business on the New York Stock  Exchange (the "NYSE")  (generally  4:00 p.m.,
Eastern time) on days that the NYSE is open for business and on any other day on
which there is sufficient  trading in the Fund's  portfolio  securities that net
asset value might be materially affected but only if on any such day the Fund is
required  to sell or redeem  shares.  The NYSE is not open for  business  on the
following  holidays:  New Year's Day,  Martin Luther King, Jr. Day,  Presidents'
Day, Good Friday,  Memorial Day,  Independence Day, Labor Day,  Thanksgiving Day
and  Christmas  Day.  The net asset  value per share of the Fund is  computed by
dividing the sum of the value of the  securities  held by the Fund plus any cash
or other assets minus all  liabilities by the total number of shares of the Fund
outstanding at such time, rounded to the nearest cent.  Expenses,  including the
investment  advisory  fee  payable to MLAM and any  account  maintenance  and/or
distribution  fees  payable to the  Distributor,  are  accrued  daily.  The Fund
employs Merrill Lynch Securities Pricing Service ("MLSPS"),  an affiliate of the
Investment  Adviser,  to provide certain securities prices for the Fund. For the
fiscal year ended  October 31, 1998,  the Fund paid MLSPS $1,305 for  securities
price quotations to compute the net asset value of the Fund.

     The per share net asset  value of Class A shares  generally  will be higher
than the per share net asset  value of shares of the other  classes,  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 Class D shares;  moreover,  the per share net asset  value of Class D
shares  generally  will be higher  than the per share net asset value of Class B
and Class C shares,  reflecting the daily expense  accruals of the  distribution
and higher  transfer  agency fees applicable with respect to Class B and Class C
shares.  It is  expected,  however,  that the per share  net asset  value of the
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 in the  over-the-counter  market are
valued at the last  available  bid price as  obtained  from  dealers  who make a
market in the securities.  Securities with remaining maturities of sixty days or
less are valued at amortized cost, which approximates  market value.  Securities
and assets for which market  quotations are not readily  available are valued at
fair value as determined in good faith by or under the direction of the Board of
Trustees of the Fund.

                      PORTFOLIO TRANSACTIONS AND BROKERAGE

Transactions in Portfolio Securities

     Subject to policies  established  by the board of Trustees of the fund, the
Investment  Adviser is responsible  for the Fund's  portfolio  decisions and the
placing of the Fund's portfolio transactions. The Fund has no obligation to deal
with  any  dealer  or group of  dealers  in the  execution  of  transactions  in
portfolio  securities.  Subject  to  the  policy  established  by the  Board  of
Trustees,  the  Investment  Adviser is primarily  responsible  for the portfolio
decisions of the Fund and the placing of its portfolio transactions.  In placing
orders,  it is the policy of the Fund to obtain the best price and execution for
its transactions.  Affiliated persons of the Fund,  including Merrill Lynch, may
serve as its  broker in  over-the-counter  transactions  conducted  on an agency
basis.

     For the fiscal years ending  December 31, 1998, 1997 and 1996 the Fund paid
no brokerage commissions to Merrill Lynch.

     The  obligations  in which the Fund  invests  are traded  primarily  in the
over-the-counter  market but may be traded on an exchange.  Where possible,  the
Fund 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. The
cost of executing  portfolio  transactions of the Fund will primarily consist of
dealer spreads and underwriting commissions.

     Under the  Investment  Company Act,  persons  affiliated  with the Fund 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  Securities  and  Exchange  Commission.   Since   over-the-counter   ("OTC")
transactions are usually principal transactions, affiliated persons of the Fund,
including Merrill Lynch, may not serve as dealer in connection with transactions
with the Fund.  Affiliated  persons of the Fund may serve as broker for the Fund
in OTC transactions  conducted on an agency basis.  Certain court decisions have
raised  questions  as to the extent to which  investment  companies  should seek
exemptions  under  the  Investment  Company  Act in order  to seek to  recapture
underwriting  and dealer  spreads from  affiliated  entities.  The Trustees have
considered all factors deemed  relevant,  and have made a  determination  not to
seek such recapture at this time. The Trustees will  reconsider this matter from
time to time.

     In  placing  orders,  it is the  policy of the Fund to obtain  the best net
results  taking into  account such factors as price  (including  the  applicable
dealer spread), the size, type and difficulty of the transaction  involved,  the
firm's  general  execution  and  operational  facilities,  the  firm's  risk  in
positioning  the securities  involved and the firm's  provision of  supplemental
investment research (such as economic data and market forecasts). Information so
received  will be in addition to and not in lieu of the services  required to be
performed by the Investment 


                                       23
<PAGE>

Adviser  under  its  Investment  Advisory  Agreement,  and the  expenses  of the
Investment Adviser will not necessarily be reduced as a result of the receipt of
such  supplemental  information.  In some cases, the Investment  Adviser may use
such  supplemental   research  in  providing  investment  advice  to  its  other
investment  advisory  accounts.  While the Investment  Adviser  generally  seeks
reasonably competitive spreads or commissions,  the Fund will not necessarily be
paying the lowest spread or commission available.

     Securities  held  by  the  Fund  may  also  be  held  by or be  appropriate
investments  for other funds for which the Investment  Adviser or its affiliates
act as an adviser or by investment  advisory clients of the Investment  Adviser.
Because of different  objectives or other factors, a particular  security may be
bought for one or more  clients  when one or more  clients  are selling the same
security.  If purchases or sales of  securities  for the Fund or other funds for
which they act as  investment  adviser or for their  advisory  clients arise for
consideration at or about the same time, transactions in such securities will be
made,  insofar as  feasible,  for the  respective  funds and clients in a manner
deemed equitable to all. To the extent that  transactions on behalf of more than
one client of the Investment  Adviser or its  affiliates  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.

                               PORTFOLIO TURNOVER

     The Investment  Adviser effects  portfolio  transactions  without regard to
holding period if, in its judgment,  such transactions are advisable in light of
a change in circumstances in general market,  economic or financial  conditions.
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 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.  High  portfolio  turnover
involves  correspondingly greater transaction costs in the form of dealer spread
and  brokerage  commissions,  which are  borne  directly  by the  Fund,  and may
increase  the  percentage  of the  Fund's  distributions  which are  taxable  to
shareholders as ordinary income.

                              SHAREHOLDER SERVICES

     The Fund offers a number of shareholder  services described below which are
designed to facilitate investment in its shares. Full details as to each of such
services and copies of the various  plans  described  below can be obtained from
the Fund,  the  Distributor  or Merrill  Lynch.  Certain of these  services  are
available only to U.S. investors.

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 long-term  capital gains  distributions.  The statements  will also show any
other activity in the account since the preceding  statement.  Shareholders will
receive separate transaction confirmations for each purchase or sale transaction
other than  automatic  investment  purchases  and the  reinvestment  of ordinary
income dividends and long-term  capital gains  distributions.  A shareholder may
make additions to his Investment Account at any time by mailing a check directly
to the Fund's Transfer Agent.

     Share  certificates  are  issued  only for full  shares  and only  upon the
specific request of the shareholder.  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 Fund's Transfer Agent.

     Shareholders  considering  transferring  their Class A 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 such  shareholder  must
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  and who do not wish to have an  Investment
Account  maintained  for such shares at the transfer agent may request 


                                       24
<PAGE>

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  shares,  and then must turn the  certificates  over to the new firm for
re-registration as described in the preceding sentence. Shareholders considering
transferring a tax-deferred  retirement account such as an individual retirement
account from Merrill Lynch to another  brokerage  firm or financial  institution
should be aware  that,  if the firm to which  the  retirement  account  is to be
transferred  will not take  delivery of shares of the Fund, a  shareholder  must
either redeem the shares (paying any applicable  CDSC) so that the cash proceeds
can be  transferred  to the account at the new firm,  or such  shareholder  must
continue to maintain a retirement  account with Merrill  Lynch for those shares.

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
(800) MER-FUND or (800) 637-3863. 

Retirement Plans

     Self-directed individual retirement accounts and other retirement plans are
available from Merrill Lynch. Under these plans,  investments may be made in the
Fund and certain of the other mutual funds sponsored by Merrill Lynch as well as
in other securities.  Merrill Lynch charges an initial  establishment fee and an
annual  custodial fee for each account.  Information with respect to these plans
is available upon request from Merrill Lynch.  The minimum  initial  purchase to
establish any such plan is $100 and the minimum subsequent purchase is $1.

     Any  Retirement  Plan which does not meet the  qualifications  to  purchase
Class A or Class D shares at net asset value may purchase  Class B shares with a
waiver of the CDSC upon redemption if the following  qualifications are met. The
CDSC is waived for any Eligible 401(k) Plan redeeming Class B shares and is also
waived for Class B  redemptions  from a 401(a)  plan  qualified  under the Code,
provided that each such plan has the same or an affiliated  sponsoring  employer
as an Eligible 401(k) Plan purchasing Class B shares  ("Eligible  401(a) Plan").
Other tax qualified  retirement  plans within the meaning of Section  401(a) and
403(b) of the Code which are provided  specialized  services (e.g.,  plans whose
participants may direct on a daily basis their plan allocations  among a menu of
investments)  by independent  administration  firms  contracted  through Merrill
Lynch may also  purchase  Class B shares with a waiver of the CDSC.  The CDSC is
also waived for any Class B shares  which are  purchased  by an Eligible  401(k)
Plan or Eligible 401(a) Plan and 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 shares  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 minimum  initial and subsequent  purchase  requirements  are
waived in connection with all the  above-referenced  Retirement Plans.  


                                       25

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 mutual fund specifically designated 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  want 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 and Class D shares outstanding  ("outstanding  Class A
or Class D shares") for Class A or Class D shares of other Select  Pricing Funds
or 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 and 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 shares charge or without a sales charge.

     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 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.


                                       26

     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  and 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  exchange  Select
Pricing   Funds  shares  for  shares  of  such  other  money  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 Fund's exchange privilege
is  modified  with  respect  to  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 is made. It is contemplated that the exchange privilege may
be applicable to other new mutual funds whose shares may be  distributed  by the
Distributor.

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  as
described  in the  Prospectus)  or Class B or Class D shares  at the  applicable
public offering price either through the  shareholder's  securities dealer or by
mail directly to the Fund's 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  whereby  the  Fund  is  authorized  through
pre-authorized  checks  or  automated  clearing  house  debits of $50 or more to
charge the regular bank account of the shareholder on a regular basis to provide
systematic additions to the Investment Account of such shareholder.  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 or more ($1 for
retirement accounts) through the CMA(R)/CBA(R) Automated Investment Program.


                                       27
<PAGE>

Automatic Dividend Program

     Unless specific  instructions to the contrary are given as to the method of
payment of dividends,  dividends will be reinvested  automatically in additional
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  monthly  payment  date of the
dividend.  Shareholders  may elect in writing to receive either their dividends,
in cash, in which event  payment will be mailed or direct  deposited on or about
the payment date. No CDSC will be imposed on  redemptions  of shares issued as a
result of the automatic reinvestment of dividends.

     Shareholders  may,  at any time,  notify  Merrill  Lynch in  writing if the
shareholder's  account is  maintained  with Merrill Lynch or notify the Transfer
Agent,  if the  shareholders'  account is maintained with the Transfer Agent, in
writing or by telephone  (1-800-MER-FUND) that they no longer wish to have their
dividends  reinvested in shares of the Fund or vice versa,  and  commencing  ten
days after 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 or redemption checks

Systematic Withdrawal Plan

     A  shareholder  of the Fund  may  elect to  receive  systematic  withdrawal
payments  from an  Investment  Account  of Class A,  Class B, Class C or Class D
shares in the form of payments by check or through  automatic  payment by direct
deposit to his bank account on either a monthly or  quarterly  basis as provided
below.  Quarterly  withdrawals are available for  shareholders who have acquired
shares of the Fund having a value,  based upon the current net asset  value,  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  either  the  dollar  amount and class of shares to be
redeemed. Redemptions will be made at net asset value as determined once by MLAM
immediately  after the declaration of dividends as of 15 minutes after the close
of business on the NYSE (generally  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 close of business 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 shares
of the Fund. 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.

     Withdrawal  payments  should  not be  considered  as  dividends,  yields or
income. Each withdrawal is a taxable event. If periodic withdrawals continuously
exceed  reinvested  dividends,  the  shareholder's  original  investment  may be
correspondingly   reduced.   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 who maintain a Systematic  Withdrawal Plan
unless such purchase is equal to at least one year's  scheduled  withdrawals  or
$1,200,  whichever  is  greater.  Periodic  investments  may not be made into an
Investment  Account from which the  shareholder  has elected to make  systematic
withdrawals.

     Alternatively,  a shareholder whose shares are held within a CMA(R), CBA(R)
or Retirement Account may elect to have shares redeemed on a monthly, bimonthly,
quarterly,  semiannual  or annual  basis  through the  CMA(R)/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
five 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  


                                       28
<PAGE>

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)/CBA(R)
Systematic  Redemption  Program  is not  available  if  Fund  shares  are  being
purchased within the account pursuant to the Automatic  Investment Program.  For
more information on the CMA(R)/CBA(R)  Systematic  Redemption Program,  eligible
shareholders should contact their Merrill Lynch Financial Consultant.

     With  respect to  redemptions  of Class B and 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 -- Contingent
Deferred  Sales  Charges -- Class B Shares" and " -- Contingent  Deferred  Sales
Charges -- 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  automatically  be applied
thereafter to Class D shares.  If an investor  wishes to change the amount being
withdrawn in a systematic withdrawal plan the investor should contact his or her
Financial Consultant.

                               DIVIDENDS AND TAXES

Dividends

     It is the  Fund's  intention  to  distribute  substantially  all of the net
investment  income of the Fund, if any. The net investment income of the Fund is
declared as dividends daily  immediately  prior to the  determination of the net
asset value of the Fund on that day and  reinvested  monthly in additional  full
and  fractional  shares of the Fund at net asset  value  unless the  shareholder
elects to receive such dividends in cash. The net investment  income of the Fund
for dividend  purposes  consists of interest and  dividends  earned on portfolio
securities,  less  expenses,  in  each  case  computed  since  the  most  recent
determination of net asset value.  Expenses of the Fund,  including the advisory
fee and any account  maintenance and/or  distribution fees (if applicable),  are
accrued  daily.  Shares  will  accrue  dividends  as long as they are issued and
outstanding. The per share dividends on Class B and Class C shares will be lower
than the per  share  dividends  on Class A and Class D shares as a result of the
account maintenance,  distribution and higher transfer agency fees applicable to
the Class B and Class C share.  Similarly,  the per share  dividends  on Class D
shares will be lower than the per share dividends on Class A shares as result of
the account  maintenance fees applicable with respect to the Class D shares. See
"Pricing of Shares --  Determination  of Net Asset Value." Shares are issued and
outstanding as of the settlement date of a purchase order to the settlement date
of a redemption order.

Taxes

     The Fund  intends to continue  to qualify  for the  special  tax  treatment
afforded regulated investment companies ("RICs") under the Internal Revenue Code
of 1986, as amended (the  "Code").  As a RIC, in any fiscal year with respect to
which the Fund distributes at least 90% of its investment company taxable income
(which  includes,  among other  items,  dividends  and interest but excludes net
long-term  capital gains in excess of net short-term  capital losses),  the Fund
(but not its  shareholders)  generally will be relieved of Federal income tax on
the  part  of its net  ordinary  income  and net  realized  capital  gains  (net
long-term  capital gains in excess of the sum of net  short-term  capital losses
and capital loss  carryovers  from prior years,  if any) which it distributes to
Class  A,  Class B,  Class C and  Class D  shareholders.  The  Fund  intends  to
distribute  substantially all of such income. To the extent the Fund retains its
net capital gains for investment,  it will be subject under current tax rates to
a federal income tax at a maximum effective rate of 35% on the amount retained.

     The Code imposes a 4%  nondeductible  excise tax on a regulated  investment
company,  such as the Fund, if it does not distribute to its shareholders during
the  calendar  year an amount  equal to the sum of (1) 98  percent of the Fund's
investment company income, with certain adjustments, for such calendar year, (2)
98 percent of the Fund's capital gain net income for the one-year  period ending
on October 31, of such calendar  year,  and


                                       29
<PAGE>

(3) all  ordinary  income and  capital  gains for  previous  years that were not
distributed  during such years.  While the Fund intends to distribute its income
and capital gains in the manner  necessary to avoid  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.  The  excise  tax is  imposed  on the  amount  by which  the  regulated
investment company does not meet the foregoing distribution requirements.

     If in any  taxable  year the Fund fails to qualify as a RIC under the Code,
the Fund will be taxed in the same  manner as an ordinary  corporation,  and any
ordinary income or capital gains paid to its shareholders will not be deductible
by the Fund in  computing  its  taxable  income.  In  addition,  in the event of
failure to qualify,  the Fund's  distributions,  to the extent  derived from the
Fund's current or accumulated  earnings and profits,  will constitute  dividends
(eligible for the  corporate  dividends-received  deduction,  subject to certain
requirements)  which are taxable to shareholders as ordinary income, even though
those  distributions might otherwise (at least in part) have been treated in the
shareholders' hands as long-term capital gains.

     If the Fund fails to qualify as a RIC for any year,  it generally  must pay
out its earnings and profits accumulated in that year less an interest charge to
the U.S.  Treasury  on 50% of such  earnings  and  profits  before  it can again
qualify as a regulated investment company.

     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.  Dividends will be taxable to shareholders as
ordinary  income or capital  gains,  whether  received in cash or  reinvested in
additional  shares  of the Fund.  Financial  Data  Services,  Inc.,  the  Fund's
transfer agent,  will send each shareholder a monthly  dividend  statement which
will include the amount of dividends  paid and  identify  whether such  dividend
represent ordinary income or capital gains. Distributions made from an excess of
net long-term  capital gains over net short-term  capital losses  ("capital gain
dividends") are taxable to shareholders as long-term  capital gains,  regardless
of the length of time the shareholders  has owned Fund shares.  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).  Although  the  Fund  may  invest  in  certain  municipal
securities,  it is not anticipated that any portion of the dividends paid by the
Fund will qualify for tax-exempt treatment to shareholders.

     Generally,  distributions  paid by the Fund are  treated as received in the
taxable year in which such distribution is made; however,  any dividend declared
by the Fund in October,  November or December of any calendar  year,  payable to
shareholders  or recorded on specified  date in such a month and  actually  paid
during January of the following year, will be treated as received on December 31
of the year in which declared.

     A  shareholder  will realize gain or loss on the sale or exchange of shares
of the Fund in an  amount  equal to the  difference  between  the  shareholder's
adjusted basis in the shares sold or exchanged and the amount  realized on their
disposition.  Generally,  gain recognized by a shareholder on the sale of shares
held for more than one year will be  taxable as  long-term  capital  gain.  If a
shareholder  holds shares primarily for sale to customers in the ordinary course
of business rather than for investment, any gain recognized on the sale of those
shares would be taxable as ordinary  income.  Any loss  recognized  on a sale or
exchange will be  disallowed  to the extent the shares  disposed of are replaced
within a period of 61 days beginning 30 days before and ending 30 days after the
shares are disposed of. In such a case, the basis of the shares acquired will be
adjusted to reflect the disallowed loss. Any loss recognized by a shareholder on
a disposition of Fund shares held by the shareholder for six months or less will
be treated as a long-term  capital  loss to the extent of any  distributions  of
capital  gains  dividends  received  or treated as having  been  received by the
shareholder  with respect to such  shares.  Shareholders  who acquire  shares on
multiple  dates should  consult  their tax advisers to determine how to allocate
the cost of stock for basis purposes.

     The  maximum  tax rates  applicable  to net  capital  gains  recognized  by
individuals  and  other  non-corporate  taxpayers  are (i) the same as  ordinary
income  rates  for  capital  assets  held  for one year or less and (ii) 20% for
capital  assets held for more than one year.  Shareholders  should consult their
own tax advisers regarding the availability and effect of a certain tax election
to mark-to-market  shares of the Fund held on January 1, 2001.  Capital gains or
losses  recognized by corporate  shareholders are subject to tax at the ordinary
income tax rates

                                       30
<PAGE>

applicable to  corporations.  The capital gains rates  described  above apply to
distributions  of capital  gain  dividends  by  regulated  investment  companies
("RICs")  such as the Fund as well as to sales and  exchanges  of shares in RICs
such as the Fund.  With respect to capital losses  recognized on dispositions of
Fund shares  held six months or less where such losses are treated as  long-term
capital  losses to the extent of prior capital gain  dividends  received on such
shares,  it is unclear how such capital losses offset the capital gains referred
to  above.  Shareholders  should  consult  their  own  tax  advisers  as to  the
application of the capital gains rates to their particular circumstances.

     No  gain or  loss  will  be  recognized  by  Class  B  shareholders  on the
conversion of their Class B shares for 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 of the converted Class B shares.

     Only  dividends  paid by the  Fund  which  are  attributable  to  dividends
received by the Fund will qualify for the 70%  dividends-received  deduction for
corporations. In addition, corporate shareholders must have held their shares in
the Fund for more than 45 days to qualify for the deduction on dividends paid by
the Fund. Because most of the Fund's income will be interest income, rather than
dividends  on common or preferred  stock,  it is unlikely  that any  substantial
proportion  of its  distributions  will be eligible  for the  dividends-received
deduction available for corporations under the Code.

     Ordinary income dividends paid to shareholders who are nonresident  aliens,
trusts,  estates,  partnerships or corporations  will be subject to a 30% United
States  withholding  tax under existing  provisions of the Code 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.

     Some  shareholders  may be subject to a 31%  withholding  tax on reportable
dividends,   capital  gains   distributions  and  redemption  payments  ("backup
withholding").  Generally,  shareholders  subject to backup  withholding will be
those for whom a certified  taxpayer  identification  number is not 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  penalties of
perjury  that such  number is correct  and that he is not  otherwise  subject to
backup   withholding.   Any  amounts   withheld  may  be  credited  against  the
shareholder's U.S. federal income tax liability.

     The  U.S.   Internal  Revenue  Service  has  issued  Treasury   Regulations
("Regulations"),  generally effective for payments made after December 31, 1998,
concerning  the  withholding  of tax and reporting  for certain  amounts paid to
nonresident  aliens  and  foreign   corporations.   Among  other  things,  these
Regulations may require  shareholders  that are not United States persons within
the meaning of the Code to furnish new  certification  of their  foreign  status
after  December 31, 1998.  Shareholders  should  consult  their own tax advisers
concerning the  applicability and effect of such Regulations on an investment in
shares of the Fund.

     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.

     In the event the Fund retains any net capital gains,  it may designate such
retained amounts as undistributed capital gains in a notice to its shareholders.
In the event such a designation is made,  shareholders subject to U.S. tax would
include in income, as long-term capital gains, their proportionate share of such
undistributed  amounts, but would be allowed a credit or refund, as the case may
be,  for  their  proportionate  share  of the 35% tax paid by the  Fund.  If the
designation  is made,  for U.S.  federal  income tax purposes,  the tax basis of
shares  owned by a  shareholder  would be  increased  by an amount  equal to the
difference  between  (i) the amount  included  in such  shareholder's  income as
long-term capital gains and (ii) such shareholder's  proportionate  share of the
35% tax paid by the Fund.

     At October 31,  1998,  the Fund had a net  capital  loss  carry-forward  of
approximately  $7,075,000  ($3,224,000  expires in 2002,  $1,996,000  expires in
2003,  $977,000  expires in 2004 and  $878,000  expires in 2005),  which will be
available to offset like amounts of any future  taxable gains.  Expired  capital
loss  carryforward in the amount of $3,938,679 has been  reclassified to paid-in
capital in excess of par.

     The  foregoing  is a general  and  abbreviated  summary  of the  applicable
provisions  of the Code and  Regulations  presently in effect.  For the complete
provisions,  reference should be made to the pertinent  sections 


                                       31
<PAGE>

of the Code and the Regulations promulgated thereunder. The Code and Regulations
are subject to change by legislative,  judicial or administrative  action either
prospectively or retroactively.

     Shareholders  are advised to consult their own tax advisers with respect to
the  application  to their  own  circumstances  of the  above-described  general
taxation  rules and with  respect to the  federal,  state,  local or foreign tax
consequences to them of an investment in shares of the Fund.

                                PERFORMANCE DATA

From time to time the Fund may include its average annual total return and other
total return data, as well as yield, in advertisements or information  furnished
to present or prospective shareholders. Total return and yield figures are based
on the Fund's  historical  performance  and are not intended to indicate  future
performance. Average annual total return and yield are determined separately for
Class A,  Class  B,  Class C and  Class D shares  in  accordance  with  formulas
specified by the SEC and take into account the maximum applicable sales charge.

     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
fees 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 in any  advertisement  or
information including performance data of the Fund.

     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) the rates of return calculated will not be average annual rates,
but rather,  actual  annual,  annualized or aggregate rate of return and (2) the
maximum  applicable  sales charge 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 charge,  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. In advertisements  distributed
to investors  whose  purchases  are subject to waiver of the CDSC in the case of
Class B and Class C shares (such as investors in certain retirement plans) or to
reduced  sales  charges  in the case of Class A and Class D shares,  performance
data may take into account the reduced, and not the maximum, sales charge or may
not take into account the  contingent  deferred  sales charges and therefore may
reflect  greater total return since,  due to the reduced sales charges or waiver
of the contingent deferred sales charge, a lower amount of expenses is deducted.
The Fund's total return may be expressed  either as a percentage  or as a dollar
amount in order to illustrate such total return on a hypothetical  investment in
the Fund at the beginning of each specified period.

     Yield  quotations will be computed based on a 30-day period by dividing (a)
the net income based on the yield to maturity of each security earned during the
period by (b) the average daily number of shares  outstanding  during the period
that were entitled to receive dividends multiplied by the maximum offering price
per share on the last day of the period.  The yield for the 30-day  period ended
October 31, 1998 was: 3.71% for Class A shares,  3.51% for Class B shares, 3.79%
for Class C shares and 3.93% for Class D shares.

     In connection with its  reorganization at the close of business on February
14, 1997,  the Fund changed its  investment  objective  from  investing  only in
assets which would permit shares of the Fund to qualify both as "liquid  assets"
under the  regulations of the Office of Thrift  Supervision and as an investment
permitted by the regulations of the National Credit Union Association to seeking
the highest  possible  current income  consistent with the protection of capital
afforded by investing in intermediate-term  debt securities issued or guaranteed
by 


                                       32

the U.S. Government,  its agencies or instrumentalities  with a maximum maturity
not  to  exceed   fifteen  years  and,   under  normal  market   conditions,   a
dollar-weighted  average maturity of six to eight years. For the period from the
commencement of the Fund's operations through its reorganization at the close of
business on February 14, 1997, the portfolio of the Fund has consisted primarily
of   securities   issued  by  the  U.S.   government   and  its   agencies   and
instrumentalities.  The  average  maturity of the Fund's  portfolio  during this
period (generally ranging from two to five years) has been somewhat shorter than
the average  maturity of the Fund of six to eight years  following the change in
its  investment  objective  upon  its  reorganization.  As a  result,  financial
information  for operations of the Fund prior to its  reorganization  may not be
indicative of its performance following its reorganization.

     Total  return  and  yield  figures  are  based  on  the  Fund's  historical
performance  and are not  intended to indicate  future  performance.  The Fund's
total return and yield will vary depending on market conditions,  the securities
held by the Fund, 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.

     Set  forth on the next page is total  return  information  relating  to the
periods prior and  subsequent to the  reorganization  of the Fund. In connection
with its  reorganization at the close of business on February 14, 1997, the Fund
changed its  investment  objective  from  investing  only in assets  which would
permit  shares  of the  Fund  to  qualify  both as  "liquid  assets"  under  the
regulations of the Office of Thrift  Supervision and as an investment  permitted
by the  regulations  of the  National  Credit Union  Association  to seeking the
highest  possible  current  income  consistent  with the  protection  of capital
afforded by investing in intermediate-term  debt securities issued or guaranteed
by the  U.S.  Government,  its  agencies  or  instrumentalities  with a  maximum
maturity not to exceed  fifteen  years and,  under normal market  conditions,  a
dollar-weighted  average maturity of six to eight years. For the period from the
commencement of the Fund's operations through its reorganization at the close of
business on February 14, 1997, the portfolio of the Fund consisted  primarily of
securities issued by the U.S. government and its agencies and instrumentalities.
The average  maturity  of the Fund's  portfolio  during  this period  (generally
ranging  from two to five  years) has been  somewhat  shorter  than the  average
maturity  of  the  Fund  of six to  eight  years  following  the  change  in its
investment  objective  upon  its  reorganization.  As a  result,  the  financial
information  in the  table  below  for  operations  of  the  Fund  prior  to its
reorganization   may  not  be  indicative  of  its  performance   following  its
reorganization.

     In order to  reflect  the  reduced  sales  charges  applicable  to  certain
investors, as described under "Purchase of Shares," the total return data quoted
by the Fund in  advertisements  directed to such investors  whose  purchases are
subject to reduced  sales  load,  in the case of Class A and Class D shares,  or
waiver of the contingent  deferred sales charge in the case of Class B and Class
C shares, may take into account the reduced,  and not the maximum,  sales charge
or may not take into account the contingent  deferred sales charge and therefore
may reflect greater total return since, due to the reduced sales charge, a lower
amount of expenses is deducted.

     On occasion, the Fund may compare its performance to that of the Standard &
Poor's 500 Index, the Dow Jones Industrial Average or performance data published
by Lipper  Analytical  Services,  Inc.,  Morningstar  Publications,  Inc., Money
Magazine, U.S. Magazine, U.S. News & World Report, Business Week, CDA Investment
Technology,  Inc.,  Forbes  Magazine  and  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.  As with other
performance data, performance comparisons should not be considered indicative of
the Fund's relative performance for any future period. In addition, from time to
time the Fund may  include its  risk-adjusted  performance  ratings  assigned by
Morningstar Publications, Inc. in advertising or supplemental sales literature.

     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 organized as an  unincorporated  business trust under the laws
of Massachusetts under the name "Merrill Lynch Institutional  Intermediate Fund"
on September 10, 1986.  At the close of business on February 14, 1997,  the Fund
was reorganized and changed its name to "Merrill Lynch  Intermediate  Government
Bond Fund." Its  executive  offices are located at One  Financial  Center,  23rd
Floor,  Boston,  Massachusetts  02111-2646  (telephone toll free  800-225-1576).
Under  the  Declaration  of  Trust,  the  Trustees  are  authorized  to issue an
indefinite  number of shares of $0.10 par value of one or more classes,  and the
Trustees have designated  four classes:  "Class A Common Stock," "Class B Common
Stock,"  "Class C Common Stock" and "Class D Common  Stock." Each Class A, Class
B, Class C and Class D share of Common Stock has equal voting  rights,  and each
such issued and  outstanding  share is  entitled to one vote and to  participate
equally in dividends and distributions declared by the Fund and in net assets of
the Fund  upon  liquidation  or  dissolution  remaining  after  satisfaction  of
outstanding liabilities. The shares of the Fund, when issued, will be fully paid
and non-assessable,  be freely transferable and have no preference,  preemptive,
conversion  or  similar  rights,  except  that the Class B,  Class C and Class D
shares bear certain expenses related to the account  maintenance fees associated
with such shares,  and Class B and Class C shares bear certain  expenses related
to the distribution of such shares.  Each class has exclusive voting rights with
respect  to  matters  relating  to such  account  maintenance  and  distribution
expenditures,  as  applicable.  See  "Purchase  of  Shares."  The  Trustees  are
authorized  to divide or combine such shares into a greater or lesser  number of
shares and to classify  and  reclassify  the shares of the Fund into  additional
classes of Common Stock at a future date.  Shares of the Fund outstanding on the
date the Fund was reorganized were reclassified as Class D shares.

     There will  normally  be no  meetings  of  shareholders  for the purpose of
electing  Trustees  unless and until  such time as less than a  majority  of the
Trustees  holding  office have been elected by  shareholders,  at which time the
Trustees  then in office will call a  shareholders'  meeting for the election of
trustees. Shareholders may, in accordance with the Declaration of Trust, cause a
meeting of  shareholders  to be held for the purpose of voting on the removal of
Trustees.  Meetings of the  shareholders  will be called upon written request of
shareholders  holding  in the  aggregate  not less  than 10% of the  outstanding
shares  having  voting  rights.  Except as set forth above,  the  Trustees  will
continue  to hold  office and  appoint  successor  trustees.  Shares do not have
cumulative  voting  rights and the holders of more than 50% of the shares of the
Fund voting for the  election of Trustees  can elect all of the  Trustees of the
Fund if they  choose to do so and in such  event the  holders  of the  remaining
shares  would not be able to elect any  Trustees.  Holders of shares of the Fund
are entitled to redeem their shares as set forth under  "Redemption  of Shares."
No amendment may be made to the  Declaration  of Trust  without the  affirmative
vote of a majority of the outstanding shares of the Fund.

     The Declaration of Trust establishing the Fund, dated September 10, 1986, a
copy of which,  together with all amendments thereto (the "Declaration"),  is on
file in the  office  of the  Secretary  of the  Commonwealth  of  Massachusetts,
provides that the name of the Fund refers to the trustees under the  Declaration
collectively as trustees, but not as individuals or personally,  and no trustee,
shareholder,  officer, employee or agent of the Fund may be held to any personal
liability,  nor may resort be had to their private property for the satisfaction
of any obligation or claim  otherwise in connection with the affairs of the Fund
but the Fund's property only shall be liable.

     Under a separate  agreement Merrill Lynch has granted the Fund the right to
use the "Merrill  Lynch" name and has reserved the right to withdraw its consent
to the use of such  name by the Fund at any  time,  or to grant  the use of such
name to any other company, and the Fund has granted Merrill Lynch, under certain
conditions,  the use of any  other  name it might  assume  in the  future,  with
respect to any corporation organized by Merrill Lynch.
