PROSPECTUS
   
April 28, 1994
    
 
                        MERRILL LYNCH READY ASSETS TRUST
    BOX 9011, PRINCETON, NEW JERSEY 08543-9011  -  PHONE NO. (609) 282-2800
                            ------------------------
 
     Merrill Lynch Ready Assets Trust (the "Trust") is a no-load money market
fund organized as a Massachusetts business trust, seeking preservation of
capital, liquidity and the highest possible current income consistent with the
foregoing objectives available from investing in a diversified portfolio of
short-term money market securities. Portfolio securities principally consist of
short-term United States Government securities, Government agency securities,
bank money instruments, corporate debt instruments, including commercial paper
and variable amount master demand notes, and repurchase and reverse repurchase
agreements. The Trust shares common goals with those investors seeking to put
reserve assets to work in an income producing and prudent manner and to make
these assets readily available without penalty. There can be no assurance that
the investment objectives of the Trust will be realized. The Trust seeks to
maintain a constant $1.00 net asset value per share, although this cannot be
assured. An investment in the Trust is neither insured nor guaranteed by the
U.S. Government.
 
     Shares of the Trust may be purchased at their net asset value without any
sales charge. The minimum initial purchase is $5,000 and subsequent purchases
generally must be $1,000 or more. For accounts advised by banks and registered
investment advisers, the minimum initial purchase is $300 and the minimum
subsequent purchase is $100. The minimum initial purchase with respect to
pension, profit sharing, individual retirement and other retirement plans is
$250 and there is no minimum on subsequent investments with respect to these
plans. The minimum initial purchase under the Merrill Lynch BlueprintSM Program
is $500 (or $50 if the shareholder elects to participate in the automatic
investment of sale proceeds option on the Merrill Lynch BlueprintSM Program
application form) and the minimum subsequent purchase is $50. Shares may be
redeemed at any time at net asset value as described herein. The Trust pays
Merrill Lynch, Pierce, Fenner & Smith Incorporated a distribution fee for
providing certain services in connection with the distribution of Trust shares.
See "Purchase of Shares" and "Redemption of Shares".

     The yield of the Trust refers to the income generated by an investment in
the Trust over a stated seven-day period. This income is then annualized; that
is, the amount of income generated by the investment during that week is assumed
to be generated each week over a 52-week period and is shown as a percentage of
the investment. The compounded annualized yield is calculated similarly but,
when annualized, the income earned by an investment in the Trust is assumed to
be reinvested. The compounded annualized yield will be somewhat higher than the
yield because of the effect of the assumed reinvestment.
 
     The yield on Trust shares normally will fluctuate on a daily basis.
Therefore, the yield for any given past period is not an indication or
representation by the Trust of future yields or rates of return on its shares.
The Trust's yield is affected by changes in interest rates on money market
securities, average portfolio maturity, the types and quality of portfolio
securities held and operating expenses. Current yield information may not
provide a basis for comparison with bank deposits or other investments which pay
a fixed yield over a stated period of time.
 
     On occasion, the Trust may compare its yield to (1) yield data (including
Donoghue's Domestic Prime and Eurodollar and Yankeedollar Funds Average)
reported by Donoghue's Money Fund Report, a widely recognized independent
publication that monitors the performance of money market mutual funds, (2) the
average yield reported by the Bank Rate Monitor National Index(TM) for money
market deposit accounts offered by the 100 leading banks and thrift institutions
in the ten largest standard metropolitan statistical areas, (3) yield data
reported by Lipper Analytical Services, Inc., Morningstar Publications, Inc.,
Money Magazine, U.S. News & World Report, Business Week, CDA Investment
Technology, Inc., Forbes Magazine and Fortune Magazine, or (4) the yield on an
investment in 90-day Treasury bills on a rolling basis, assuming quarterly
compounding. As with yield quotations, yield comparisons should not be
considered representative of the Trust's yield or relative performance for any
future period.
 
                       INVESTMENT OBJECTIVES AND POLICIES
 
     The investment objectives of the Trust are to seek preservation of capital,
liquidity and the highest possible current income consistent with these
objectives available from investing in a diversified portfolio of short-term
money market securities. The investment objectives are fundamental policies of
the Trust which may not be changed without a vote of the majority of the
outstanding shares of the Trust.
 
     Investment in the Trust offers several benefits. The Trust seeks to provide
as high a yield potential as is available, consistent with the preservation of
capital, from short-term money market securities utilizing
 
                                        4
<PAGE>   7
 
professional money market management, block purchases of securities and yield
improvement techniques. It provides high liquidity because of its redemption
features and seeks reduced risk resulting from diversification of assets. There
can be no assurance that the investment objectives of the Trust will be
realized. Certain expenses are borne by investors, including advisory and
management fees, administrative costs and operational costs.
 
   
     In managing the Trust, Merrill Lynch Asset Management, L.P. (the
"Manager"), will employ a number of professional money management techniques,
including varying the composition of investments and the average maturity of the
portfolio based on its assessment of the relative values of the various money
market securities and future interest rate patterns. These assessments will
respond to changing economic and money market conditions and to shifts in fiscal
and monetary policy. The Manager also will seek to improve yield by taking
advantage of yield disparities that regularly occur in the money market. For
example, market conditions frequently result in similar securities trading at
different prices. Also, there frequently are differences in the yields between
the various types of money market securities. The Trust seeks to enhance yield
by purchasing and selling securities based on these yield disparities.
    
 
     The following is a description of the types of money market securities in
which the Trust may invest:
 
          United States Government Securities:  Marketable securities issued by
     or guaranteed as to principal and interest by the U.S. Government and
     supported by the full faith and credit of the United States.
 
          United States Government Agency Securities:  Debt securities issued by
     Government-sponsored enterprises, Federal agencies and certain
     international institutions which are not direct obligations of the United
     States but involve Government sponsorship or guarantees by Government
     agencies or enterprises. The U.S. Government is not obligated to provide
     financial support to these instrumentalities.
 
          Bank Money Instruments:  The Trust may invest in U.S.
     dollar-denominated obligations of U.S. and foreign depository institutions,
     including commercial and savings banks and savings and loan associations.
     Such obligations include certificates of deposit, bankers' acceptances,
     time deposits and deposit notes. For example, the obligations may be issued
     by U.S. or foreign depository institutions, foreign branches or
     subsidiaries of U.S. depository institutions ("Eurodollar" obligations),
     U.S. branches or subsidiaries of foreign depository institutions
     ("Yankeedollar" obligations) or foreign branches or subsidiaries of foreign
     depository institutions. Eurodollar and Yankeedollar obligations and
     obligations of branches or subsidiaries of foreign depository institutions
     may be general obligations of the parent bank or may be limited to the
     issuing branch or subsidiary by the terms of the specific obligations or by
     government regulation. Investments in obligations of foreign depository
     institutions and their foreign branches and subsidiaries will only be made
     if determined to be of comparable quality to other investments permissible
     for the Trust. The Trust will not invest more than 25% of its total assets
     (taken at market value at the time of each investment) in obligations of
     foreign depository institutions and their foreign branches and
     subsidiaries.
 
          Commercial Paper and Other Short-term Obligations:  Commercial paper
     (including variable amount master demand notes), which refers to
     short-term, unsecured promissory notes issued by corporations, partnerships
     and trusts to finance short-term credit needs, and non-convertible debt
     securities (e.g., bonds and debentures) with no more than 397 days (13
     months) remaining to maturity at the date of purchase. Short-term
     obligations issued by trusts include mortgage-related or asset-backed debt
     instruments, including pass-through certificates representing
     participations in, or bonds and notes backed by, pools of mortgage, credit
     card, automobile or other types of receivables.
 
                                        5
<PAGE>   8
 
          Foreign Short-term Debt Instruments.  The Trust may also invest in
     U.S. dollar-denominated commercial paper and other short-term obligations
     issued by foreign entities. Such investments are subject to quality
     standards similar to those applicable to investments in comparable
     obligations of domestic issuers. Investments in foreign entities in general
     involve the same risks as those described in the Statement of Additional
     Information in connection with investments in Eurodollar and Yankeedollar
     obligations and obligations of foreign depository institutions and their
     foreign branches and subsidiaries.
 
     The following is a description of other types of investments or investment
practices in which the Trust may invest or engage:
 
          Repurchase Agreements; Purchase and Sale Contracts.  The Trust may
     invest in repurchase agreements or purchase and sale contracts involving
     the money market securities described above. Repurchase agreements and
     purchase and sale contracts may be entered into only with a member bank of
     the Federal Reserve System or a primary dealer in U.S. Government
     securities. Under such agreements, the bank or primary dealer agrees, on
     entering into the contract, to repurchase the security at a mutually agreed
     on 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. In the case of repurchase agreements, the
     prices at which the trades are conducted do not reflect accrued interest on
     the underlying obligations; whereas, in the case of purchase and sale
     contracts, the prices take into account accrued interest. 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. In the case of a
     repurchase agreement, the Trust 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;
     the Trust does not have the right to seek additional collateral in the case
     of purchase and sale contracts. 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 Trust but only constitute
     collateral for the seller's obligation to pay the repurchase price.
     Therefore, the Trust may suffer time delays and incur costs or possible
     losses in connection with the disposition of the collateral. A purchase and
     sale contract differs from a repurchase agreement in that the contract
     arrangements stipulate that the securities are owned by the Trust. In the
     event of a default under such a repurchase agreement or under a purchase
     and sale contract, instead of the contractual fixed rate of return, the
     rate of return to the Trust shall be dependent on intervening fluctuations
     of the market value of such security and the accrued interest on the
     security. In such event, the Trust 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.
 
     Reverse Repurchase Agreements.  The Trust may enter into reverse repurchase
agreements which involve the sale of money market securities held by the Trust,
with an agreement to repurchase the securities at an agreed on price, date and
interest payment. During the time a reverse repurchase agreement is outstanding,
the Trust will maintain a segregated custodial account containing U.S.
Government or other appropriate high-grade debt securities having a value equal
to the repurchase price.
 
     Lending of Portfolio Securities.  The Trust may lend portfolio securities
(with a value not in excess of 20% of its total assets) to brokers, dealers and
financial institutions and receive collateral in cash or securities issued or
guaranteed by the U.S. Government which will be maintained at all times in an
amount equal to at least 100% of the current market value of the loaned
securities. During the period of the loan, the Trust receives the income on both
the loaned securities and the collateral and thereby increases its yield.
 
                                        6
<PAGE>   9
 
     Preservation of capital is a prime investment objective of the Trust, and
while the types of money market securities in which the Trust invests generally
are considered to have low principal risk, such securities are not completely
risk free. There is a risk of the failure of issuers to meet their principal and
interest obligations. Repurchase agreements may be construed to be
collateralized loans by the purchaser to the seller secured by the securities
transferred to the purchaser. 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 Trust but only constitute collateral for the
seller's obligation to pay the repurchase price. With respect to repurchase
agreements, purchase and sale contracts, reverse repurchase agreements and the
lending of portfolio securities by the Trust, there is also the risk of the
failure of the parties involved to repurchase at the agreed on price or to
return the securities involved in such transactions, in which event the Trust
may suffer time delays and incur costs or possible losses in connection with
such transactions.
 
     Bank money instruments in which the Trust invests must be issued by
depository institutions with total assets of at least $1 billion, except that up
to 10% of total assets (taken at market value) may be invested in certificates
of deposit of smaller institutions if such certificates of deposit are Federally
insured. Investments in Eurodollar and Yankeedollar obligations may not exceed
25% of total assets. For purposes of this requirement, the Trust treats bank
money instruments issued by U.S. branches or subsidiaries of foreign banks as
obligations issued by domestic banks (not subject to the 25% limitation) if the
branch or subsidiary is subject to the same banking regulation as U.S. banks.
 
     The Trust's investments in short-term corporate debt and bank money
instruments will be rated, or will be issued by issuers who have been rated, in
one of the two highest rating categories for short-term debt obligations by a
nationally recognized statistical rating organization (an "NRSRO") or, if not
rated, will be of comparable quality as determined by the Trustees of the Trust.
The Trust's investments in corporate bonds and debentures (which must have
maturities at the date of purchase of 397 days (13 months) or less) will be in
issuers who have received from an NRSRO a rating, with respect to a class of
short-term debt obligations that is comparable in priority and security with the
investment, in one of the two highest rating categories for short-term
obligations or, if not rated, will be of comparable quality as determined by the
Trustees of the Trust. Currently, there are six NRSROs: Duff & Phelps Inc.,
Fitch Investors Services, Inc., IBCA Limited and its affiliate IBCA Inc.,
Thompson BankWatch, Inc., Moody's Investors Service, Inc. and Standard & Poor's
Corporation.
 
     A regulation of the Securities and Exchange Commission limits investments
by the Trust in securities issued by any one issuer (other than the U.S.
Government, its agencies or instrumentalities) ordinarily to not more than 5% of
its total assets, or in the event that such securities do not have the highest
rating, not more than 1% of its total assets. In addition, such regulation
requires that not more than 5% of the Trust's total assets be invested in
securities that do not have the highest rating.
 
     The Trust may purchase money market securities on a forward commitment
basis at fixed purchase terms. The purchase will be recorded on the date the
Trust enters into the commitment and the value of the security thereafter will
be reflected in the calculation of the Trust'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 Trust will be established with its custodian consisting
of cash or liquid money market securities having a market value at all times at
least equal to the amount of the forward commitment.
 
     For purposes of its investment policies, the Trust defines short-term money
market securities as securities having a maturity of no more than 762 days (25
months) in the case of U.S. Government and agency securities and no more than
397 days (13 months) in the case of all other securities. The dollar-weighted
 
                                        7
<PAGE>   10
 
   
average maturity of the Trust's Portfolio will not exceed 90 days. During the
Trust's fiscal year ended December 31, 1993, the average maturity of its
portfolio ranged from 51 days to 89 days.
    
 
     Investment Restrictions.  The Trust has adopted a number of restrictions
and policies relating to the investment of its assets and its activities, which
are fundamental policies and may not be changed without the approval of the
holders of a majority of the Trust's outstanding voting securities, as defined
in the Investment Company Act of 1940 (the "Investment Company Act"). Among the
more significant restrictions, the Trust may not: (1) purchase any securities
other than (i) money market and (ii) other securities described under
"Investment Objectives and Policies"; (2) invest more than 25% of its total
assets (taken at market value at the time of each investment) in the securities
of issuers in any particular industry (other than U.S. Government securities,
Government agency securities or bank money instruments); (3) (i) invest more
than 5% of its total assets (taken at market value at the time of each
investment) in the securities (other than U.S. Government or Government agency
securities) of any one issuer (including repurchase agreements and purchase and
sale contracts with any one bank) except that up to 25% of the value of the
Trust's total assets may be invested without regard to such 5% limitation but
shall instead be subject to a 10% limitation, (ii) purchase more than 10% of the
outstanding securities of an issuer except that this restriction shall not apply
to U.S. Government or Government agency securities, bank money instruments,
repurchase agreements and purchase and sale contracts; (4) enter into repurchase
agreements or purchase and sale contracts if, as a result, more than 10% of the
Trust's net assets (taken at market value at the time of each investment) would
be subject to repurchase agreements or purchase and sale contracts maturing in
more than seven days; and (5) borrow amounts in excess of 20% of its total
assets, taken at market value, and then only from banks as a temporary measure
for extraordinary or emergency purposes [usually only "leveraged" investment
companies may borrow in excess of 5% of their assets; however, the Trust will
not borrow to increase income but only to meet redemption requests which might
otherwise require untimely dispositions of portfolio securities; interest paid
on such borrowings will reduce net income]. The Trust will not purchase
securities while borrowings described in investment restriction (5) are
outstanding except to honor prior commitments.

MANAGEMENT AND ADVISORY ARRANGEMENTS
 
   
     The Manager is owned and controlled by ML & Co., a financial services
holding company and the parent of Merrill Lynch. The Manager or an affiliate of
the Manager, Fund Asset Management, L.P. ("FAM"), acts as the investment adviser
for more than 90 registered investment companies and provides investment
advisory services to individual and institutional accounts. As of February 28,
1994, the Manager and FAM had a total of approximately $164.4 billion in
investment company and other portfolio assets under management, including
accounts of certain affiliates of the Manager.
    
 
   
     The investment advisory agreement with the Manager (the "Management
Agreement") provides that, subject to the direction of the Trustees, the Manager
is responsible for the actual management of the Trust's portfolio and constantly
reviews the Trust's holdings in light of its own research analysis and that from
other relevant sources. The responsibility for making decisions to buy, sell or
hold a particular security rests with the Manager subject to review by the Board
of Trustees. The Manager performs certain of the other administrative services
and provides all the office space, facilities, equipment and necessary personnel
for management of the Trust.
    
 
   
     The Manager receives compensation at the annual rate of 0.50% of the
portion of average net assets not exceeding $500 million; this rate is reduced
at several breakpoints for net assets in excess of $500 million. For the fiscal
year ended December 31, 1993, the total management fee paid by the Trust to the
Manager aggregated $25,841,742 (based on average net assets of approximately
$7.3 billion) and the effective fee rate was 0.36%. At February 28, 1994, the
net assets of the Trust aggregated approximately $6.7 billion. At this asset
level, the annual effective fee rate is approximately 0.36% of average net
assets and the annual management fee would aggregate approximately $24.1
million.
    
 
   
     The Management Agreement obligates the Trust to pay certain expenses
incurred in its operations, including, among other things, the management fee,
legal and audit fees, unaffiliated Trustees' fees and expenses, registration
fees, custodian and transfer agency fees, accounting and pricing costs and
certain of the costs of printing proxies, shareholder reports, prospectuses and
statements of additional information. Accounting services are provided to the
Trust by the Manager, and the Trust reimburses the Manager for its costs in
connection with such services. For the fiscal year ended December 31, 1993, the
amount of such reimbursement was $274,854. During 1993, the ratio of operating
expenses, excluding distribution fees, to average net assets was .53%.
    
 
TRANSFER AGENCY SERVICES
 
   
     Financial Data Services, Inc. (the "Transfer Agent"), which is a
wholly-owned subsidiary of ML & Co., acts as the Trust's transfer agent pursuant
to a transfer agency agreement (the "Transfer Agency Agreement"). Pursuant to
the Transfer Agency Agreement, the Transfer Agent is responsible for the
issuance,
    
 
                                        9
<PAGE>   12
 
   
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 $13.00 per shareholder account for the first 300,000 accounts, $12.50
per shareholder account for the next 300,000 accounts, $12.00 per shareholder
account for the next 300,000 accounts and $11.00 per shareholder account
thereafter, and is entitled to reimbursement for out-of-pocket expenses incurred
by it under the Transfer Agency Agreement. For the fiscal year ended December
31, 1993, the total fee paid by the Trust to the Transfer Agent pursuant to the
Transfer Agency Agreement was $11,259,945. At February 28, 1994, the Trust had
605,417 shareholder accounts. At this level of accounts, the annual fee payable
to the Transfer Agent would aggregate approximately $7.7 million (including
certain subaccounts on which the standard annual transfer agent fees are not
assessed).
    
 
                               PURCHASE OF SHARES
 
   
     The Trust is offering its shares without sales charge at a public offering
price equal to the net asset value (normally $1.00 per share) next determined
after a purchase order becomes effective. Share purchase orders are effective on
the date Federal Funds become available to the Trust. If Federal Funds are
available to the Trust prior to 4:00 P.M., New York time, on any business day,
the order will be effective on that day. Shares purchased will begin accruing
dividends on the day following the date of purchase. Any order may be rejected
by the Trust or the Distributor.
    
 
METHODS OF PAYMENT
 
   
     Payment Through Securities Dealers.  Investment in the Trust may be made
through securities dealers, including Merrill Lynch, who have entered into
selected dealer agreements with the Distributor. In such a case, the dealer will
transmit payment to the Trust on behalf of the investor and will supply the
Trust with the required account information. Generally, purchase orders placed
through Merrill Lynch will be made effective on the day following the day the
order is placed with Merrill Lynch, except that orders received through the
Merrill Lynch BlueprintSM Program in some circumstances may be executed two
business days following the day the order is placed with Merrill Lynch.
Investments in the Trust through the Merrill Lynch BlueprintSM Program
("Blueprint") may be made only through Merrill Lynch. Such orders should be sent
to Merrill Lynch, Pierce, Fenner & Smith Incorporated, Attention: The
BlueprintSM Program, P.O. Box 30441, New Brunswick, New Jersey 08989-0441.
Blueprint maintains a toll-free telephone number for inquiries: (800) 637-3766.
Investors who are not placing orders through Blueprint and who desire same day
effectiveness should utilize the Payment by Wire procedure described below.
Investors with free cash credit balances (i.e., immediately available funds) in
securities accounts of Merrill Lynch will not have their funds invested in the
Trust until the day after the order is placed with Merrill Lynch and will not
receive the daily dividend which would have been received had their funds been
invested in the Trust on the day the order was placed with Merrill Lynch.
Merrill Lynch has an order procedure pursuant to which investors can have the
proceeds from the sale of listed securities invested in shares of the Trust on
the day investors receive such proceeds in their Merrill Lynch securities
accounts. Effective June 1, 1990, Merrill Lynch implemented new order procedures
pursuant to which investors can have the proceeds from the sale of most
securities invested in shares of the Trust on the day following the day
investors receive such proceeds in their Merrill Lynch securities accounts.
    
 
   
     Payment by Wire.  An expeditious method of investing in the Trust is
available through the transmittal of Federal Funds by wire to the Trust's
Transfer Agent. The Trust will not be responsible for delays in the wiring
system. To purchase shares by wiring Federal Funds, payment should be wired to
First Union National Bank of Florida. Shareholders should give their financial
institutions the following wiring instructions:
    
 
                                       10
<PAGE>   13
 
ABA #063000021, DDA #11260006118, Financial Data Services, Inc. The wire should
be identified as a payment to Merrill Lynch Ready Assets Trust and should
include the shareholder's name and account number. Failure to submit the
required information may delay investment. Investors are urged to make payment
by wire in Federal Funds.
 
     Payment to the Transfer Agent.  Purchase orders for which remittance is to
be made by check may be submitted directly by mail or otherwise to the Transfer
Agent. Purchase orders by mail should be sent to Financial Data Services, Inc.,
Transfer Agency Operations Department, P.O. Box 45290, Jacksonville, Florida
32232-5290. Purchase orders which are sent by hand should be delivered to
Financial Data Services, Inc., Transfer Agency Operations Department, 4800 Dear
Lake Drive East, Jacksonville, Florida 32246-6484. Investors opening a new
account must enclose a completed Purchase Application. Existing shareholders
should enclose the detachable stub from a monthly account statement which they
have received. Checks should be made payable to Merrill Lynch Funds Distributor,
Inc. Certified checks are not necessary, but checks are accepted subject to
collection at full face value in United States funds and must be drawn in United
States dollars on a United States bank. Payments for the accounts of
corporations, foundations and other organizations may not be made by third party
checks.
 
DISTRIBUTION PLAN
 
     The Trust has adopted a Shareholder Servicing Plan and Agreement (the
"Plan") in compliance with Rule 12b-1 under the Investment Company Act pursuant
to which the Trust is authorized to pay Merrill Lynch a fee at the annual rate
of 0.125% of average daily net asset value of Trust accounts maintained through
Merrill Lynch. The Plan reimburses Merrill Lynch only for actual expenses
incurred in the fiscal year in which the fee is paid. The fee is principally to
provide compensation to Merrill Lynch financial consultants and other Merrill
Lynch personnel for providing certain services to shareholders who maintain
their Trust accounts through Merrill Lynch. The fee is for direct personal
services to Trust shareholders. Under the Plan, as amended to date, Merrill
Lynch, in its sole discretion, may expend out of the fee an amount not exceeding
0.01% of such average daily net asset value as reimbursement for expenditures
incurred in advertising activities promoting the sale, marketing and
distribution of the shares of the Trust.
 
   
     For the fiscal year ended December 31, 1993, $8,501,923 was paid to Merrill
Lynch pursuant to the Plan (based on average net assets subject to the Plan of
$7.3 billion). At February 28, 1994, the net assets of the Trust subject to the
Plan aggregated approximately $6.7 billion. At this asset level, the annual fee
payable to Merrill Lynch pursuant to the Plan would aggregate approximately $7.9
million.
    
 
                              REDEMPTION OF SHARES
 
     The Trust is required to redeem for cash all full and fractional shares of
the Trust. The redemption price is the net asset value per share next determined
after receipt by the Transfer Agent of proper notice of redemption as described
in accordance with one of the procedures set forth below. If such notice is
received by the Transfer Agent by 4:00 P.M., New York time, on any day during
which the New York Stock Exchange or New York banks are open for business, the
redemption will be effective on such day and payment will be made on the next
business day. If the notice is received after 4:00 P.M., New York time, the
redemption will be effective on the next business day and payment will be made
on the second business day thereafter. If notice of a redemption of shares held
in connection with the Merrill Lynch BlueprintSM Program is received by Merrill
Lynch by 4:00 P.M., New York time, it will be effective on the business day
following receipt of the redemption request. If the notice is received after
4:00 P.M., New York time, the redemption will be effective on the second
business day thereafter.
 
                                       11
<PAGE>   14
 
   
     At various times, the Trust may be requested to redeem shares for which
good payment has not yet been received. The Trust may delay, or cause to be
delayed, the payment of redemption proceeds until such time as it or its
Transfer Agent has assured itself that good payment has been collected for the
purchase of such shares. Normally, this delay will not exceed 10 days. In
addition, the Trust reserves the right not to honor redemption checks or
requests for Federal Funds redemptions where the shares to be redeemed have been
purchased by check within 10 days prior to the date the redemption request is
received by the Trust's Transfer Agent.
    
 
METHODS OF REDEMPTION
 
     Set forth below is information as to the five methods pursuant to which
shareholders may redeem shares. In certain instances, the Transfer Agent may
require documents in connection with redemptions.
 
     Redemption by Check.  Shareholders may redeem shares by check in an amount
not less than $500. At the shareholder's request, the Transfer Agent will
provide the shareholder with checks drawn on the custody account of the Trust
with its Custodian. These checks can be made payable to the order of any person
in any amount not less than $500; however, these checks may not be used to
purchase securities in transactions with Merrill Lynch. The payee of the check
may cash or deposit it like any check drawn on a bank. When such a check is
presented to the Transfer Agent for payment, the Transfer Agent will present the
check to the Trust as authority to redeem a sufficient number of full and
fractional shares in the shareholder's account to cover the amount of the check.
This enables the shareholder to continue earning daily dividends until the check
is cleared. Canceled checks will be returned to the shareholder by the Transfer
Agent.
 
     Shareholders will be subject to the Transfer Agent's rules and regulations
governing such checking accounts, including the right of the Transfer Agent not
to honor checks in amounts exceeding the value of the shareholder's account at
the time the check is presented for payment. The Trust or the Transfer Agent may
modify or terminate the redemption by check privilege at any time on 30 days'
notice to participating shareholders. In order to be eligible for the redemption
by check privilege, purchasers should check the box under the caption "Check
Redemption Privilege" in the Purchase Application. The Transfer Agent will then
send checks to the shareholder.
 
   
     Federal Funds Redemption.  Shareholders also may arrange to have redemption
proceeds of $5,000 or more wired in Federal Funds to a pre-designated bank
account. In order to be eligible for Federal Funds redemption, the shareholder
must designate on his Purchase Application the domestic commercial bank and
account number to receive the proceeds of his redemption and must have his
signature on the Purchase Application guaranteed. The redemption request for
Federal Funds redemption may be made by telephone, wire or letter (no signature
guarantee required) to the Transfer Agent and, if received by 4:00 P.M., New
York time, the redemption proceeds will be wired to the investor's
pre-designated bank account on the next business day. Shareholders may effect
Federal Funds redemptions by telephoning the Transfer Agent at (800) 221-7210
toll-free. The Trust will employ reasonable procedures to confirm that
instructions communicated by telephone are genuine; if it does not, the Trust
may be liable for any losses due to fraudulent or unauthorized instructions.
Among other things, redemption proceeds may only be wired into the bank account
designated on the Purchase Application. The investor must independently verify
this information at the time the redemption request is made.
    
 
   
     Repurchase Through Securities Dealers.  The Trust will repurchase shares
through securities dealers. The Trust normally will accept orders to repurchase
shares by wire or telephone from dealers for customers at the net asset value
next computed after receipt of the order from the dealer, provided that such
request for repurchase is received from the dealer prior to 4:00 P.M., New York
time, on any business day. These
    
 
                                       12
<PAGE>   15
 
   
repurchase arrangements are for the convenience of shareholders and do not
involve a charge by the Trust; however, dealers may impose a charge on the
shareholder for transmitting the notice of repurchase to the Trust. Redemption
of Trust shares held in connection with Blueprint may be made only through
Merrill Lynch. Such a redemption may be made by submitting a written notice by
mail directly to Merrill Lynch, Pierce, Fenner & Smith Incorporated, Attention:
The BlueprintSM Program, P.O. Box 30441, New Brunswick, New Jersey 08989-0441.
Investors whose shares are held through Blueprint also may effect notice of
redemption by telephoning Merrill Lynch at (800) 637-3766 toll-free. The Trust
reserves the right to reject any order for repurchase through a securities
dealer, but it may not reject properly submitted requests for redemption as
described below. The Trust will promptly notify any shareholder of any rejection
of a repurchase with respect to his shares. For shareholders repurchasing
through their securities dealer, payment will be made by the Transfer Agent to
the dealer.
    
 
     Regular Redemption.  Shareholders may redeem shares by submitting a written
notice by mail directly to the Transfer Agent, Financial Data Services, Inc.,
Transfer Agency Operations Department, P.O. Box 45290, Jacksonville, Florida
32232-5290. Redemption requests which are sent by hand should be delivered to
Financial Data Services, Transfer Agency Operations Department, 4800 Deer Lake
Drive East, Jacksonville, Florida 32246-6484. Redemption requests should not be
sent to the Trust. The notice requires the signatures of all persons in whose
names the shares are registered, signed exactly as their names appear on the
Transfer Agent's register. The signatures on the redemption request must be
guaranteed by an "eligible guarantor institution" as such is defined in Rule
17Ad-15 under the Securities Exchange Act of 1934, the existence and validity of
which may be verified by the Transfer Agent through the use of industry
publications. Notarized signatures are not sufficient.
 
     Automatic Redemption.  Merrill Lynch has instituted an automatic redemption
procedure applicable to shareholders of the Trust who maintain securities
accounts with Merrill Lynch. Merrill Lynch may utilize this procedure, which is
not applicable to margin accounts, to satisfy amounts due it by the shareholder
as a result of account fees and expenses owed to Merrill Lynch or one of its
affiliates or as a result of purchases of securities or other transactions in
the shareholder's securities account. Under this procedure, unless the
shareholder notifies Merrill Lynch to the contrary, the shareholder's Merrill
Lynch securities account will be scanned each business day prior to 4:00 P.M.,
New York time, after application of any cash balances in the account, a
sufficient number of Trust shares will be redeemed at the 4:00 P.M., New York
time, pricing that day to satisfy any amounts for which the shareholder is
obligated to make payment to Merrill Lynch or one of its affiliates. Redemptions
will be effected on the business day preceding the date the shareholder is
obligated to make such payment, and Merrill Lynch or its affiliate will receive
the redemption proceeds on the business day following the redemption date.
Shareholders will receive all dividends declared and reinvested through the date
of redemption.
 
                            ------------------------
 
     Due to the relatively high cost of maintaining accounts of less than
$1,000, the Trust reserves the right to redeem shares in any account for their
then current value (which will be promptly paid to the shareholder), if at any
time the total investment does not have a value of at least $1,000. Shareholders
will be notified that the value of their account is less than $1,000 and allowed
two months to make an additional investment before the redemption is processed.
In such event, the $1,000 minimum on subsequent investment will not be
applicable.

                              SHAREHOLDER SERVICES
 
     The Trust offers a number of shareholder services designed to facilitate
investment in its shares. Full details as to each of such services, copies of
the various plans described below and instructions as to how to participate in
the various services or plans, or to change options with respect thereto can be
obtained from the Trust, the Distributor or Merrill Lynch. Included in such
services are the following:
 
     Investment Account.  Each shareholder whose account is maintained at the
Transfer Agent has an Investment Account and will receive from the Transfer
Agent a monthly report showing the activity in his account for the month. A
shareholder may make additions to his Investment Account at any time by
purchasing shares at the public offering price either through his securities
dealer, by wire or by mail directly to the Transfer Agent, acting as agent for
his dealer. A shareholder may ascertain the number of shares in his Investment
Account by telephoning the Transfer Agent at (800) 221-7210 toll-free. The
Transfer Agent will furnish this information only after the shareholder has
specified the name, address, account number and social security number of the
registered owner or owners. Shareholders also may maintain their accounts
through Merrill Lynch. Upon the transfer of shares out of a Merrill Lynch
brokerage account, an Investment Account in the transferring shareholder's name
may be opened at the Transfer Agent. 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 Trust, a shareholder must either redeem the
shares 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 at
Merrill Lynch for those shares.
 
     Exchange Privilege.  Shareholders of the Trust have an exchange privilege
with Class A shares of certain other mutual funds sponsored by Merrill Lynch.
There is currently no limitation on the number of times a shareholder may
exercise the exchange privilege. The exchange privilege may be modified or
terminated at any time in accordance with the rules of the Securities and
Exchange Commission. Exercise of the exchange privilege is treated as a sale for
Federal income tax purposes. For further information, see "Shareholder
Services--Exchange Privilege" in the Statement of Additional Information.
 
     Accrued Monthly Payout Plan.  Shareholders desiring their dividends in cash
may enroll in this plan and receive monthly cash payments resulting from the
redemption of the shares received on dividend reinvestments during the month.
 
   
     Systematic Withdrawal and Automatic Investment Plans.  A shareholder may
elect to receive systematic withdrawal payments from his Investment Account 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. Regular additions may
be made to an investor's Investment Account by prearranged charges to his
regular bank account at a minimum of $50 per month.
    
 
     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 Trust and in certain of the other mutual funds
whose shares are distributed by the Distributor, as well as in other securities.
Merrill Lynch charges an initial establishment fee and an annual custodial fee
for each account. In addition, eligible shareholders of the Trust may
participate in a variety of qualified employee benefit plans which are available
from the Distributor. The minimum initial purchase to establish any such plan is
$250.
 
                                       14

                             PORTFOLIO TRANSACTIONS
 
   
     The money market securities in which the Trust invests are traded primarily
in the over-the-counter market. Where possible, the Trust 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. Money market securities
generally are traded on a net basis and normally do not involve either brokerage
commissions or transfer taxes. The cost of executing portfolio transactions will
consist primarily of dealer spreads and underwriting commissions. Under the
Investment Company Act, persons affiliated with the Trust are prohibited from
dealing with the Trust as a principal in the purchase and sale of securities
unless an exemptive order allowing such transactions is obtained from the
Securities and Exchange Commission. An affiliated person of the Trust may serve
as its broker in over-the-counter transactions conducted on an agency basis. The
Securities and Exchange Commission has issued an exemptive order permitting the
Trust to conduct certain principal transactions with Merrill Lynch Government
Securities Inc. or its subsidiary, Merrill Lynch Money Markets Inc. subject to
certain terms and conditions. During the fiscal year ended December 31, 1993,
the Trust engaged in 152 transactions pursuant to such orders aggregating
approximately $5.6 billion.
    
 
                             ADDITIONAL INFORMATION
 
DIVIDENDS
 
   
     Dividends are declared and reinvested daily in the form of additional
shares at net asset value. Shareholders will receive statements monthly as to
such reinvestments. Shareholders liquidating their holdings will receive on
redemption all dividends declared and reinvested through the date of redemption.
Since the net income (including realized gains and losses on the portfolio
assets) is declared as a dividend in shares each time the net income of the
Trust is determined, the net asset value per share of the Trust normally remains
constant at $1.00 per share. Fluctuations in value may be reflected in the
number of outstanding shares in the shareholder's account.
    
 
     Net income (from the time of the immediately preceding determination
thereof) consists of (i) interest accrued and/or discount earned (including both
original issue and market discount), (ii) plus or minus all realized gains and
losses on portfolio securities, (iii) less the estimated expenses of the Trust
applicable to that dividend period.
 
DETERMINATION OF NET ASSET VALUE
 
   
     The net asset value of the Trust is determined by the Manager once daily,
immediately after the daily declaration of dividends, as of 4:00 P.M., New York
time, on each day during which the New York Stock Exchange or New York banks are
open for business. The net asset value per share is computed pursuant to the
"penny-rounding" method by dividing the value of the securities held by the
Trust plus any cash or other assets (including interest accrued but not yet
received) minus all liabilities by the total number of shares outstanding at
such time. The money market securities in which the Trust invests are valued at
the most recent bid price or yield equivalent as obtained from dealers that make
markets in such securities. 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 Trustees of the Trust. Securities with a remaining maturity of
60 days or less are valued on an amortized cost basis. This involves valuing an
instrument at its cost and thereafter assuming a constant amortization to
maturity of any discount or premium, regardless of the impact of fluctuating
interest rates on the market value of the instrument.

TAXES
 
   
     The Trust 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"). If it so qualifies, the Trust (but not its
shareholders) will not be subject to Federal income tax on the part of its net
ordinary income and net realized capital gains which it distributes to
shareholders. The Trust intends to distribute substantially all of such income.
    
 
   
     Dividends paid by the Trust from its ordinary income and distributions of
the Trust's net realized short-term capital gains (together referred to
hereafter as "ordinary income dividends") are taxable to shareholders as
ordinary income. Distributions made from the Trust's net realized long-term
capital gains ("capital gain dividends") are taxable to shareholders as
long-term capital gains, regardless of the length of time the shareholder has
owned Trust shares. Distributions in excess of the Trust'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).
    
 
   
     Dividends are taxable to shareholders even though they are reinvested in
additional shares of the Trust. Not later than 60 days after the close of its
taxable year, the Trust will provide its shareholders with a written notice
designating the amounts of any ordinary income dividends or capital gain
dividends. Distributions by the Trust, whether from ordinary income or capital
gains, will not be eligible for the dividends received deduction allowed to
corporations under the Code. If the Trust pays a dividend in January which was
declared in the previous October, November or December to shareholders of record
on a specified date in one of such months, then such dividend will be treated
for tax purposes as being paid by the Trust and received by its shareholders on
December 31 of the year in which such dividend was declared.
    
 
   
     If the value of assets held by the Trust declines, the Board of Directors
may authorize a reduction in the number of outstanding shares in shareholders'
accounts so as to preserve a net asset value of $1.00 per share. After such a
reduction, the basis of eliminated shares would be added to the basis of
shareholders' remaining Trust shares, and any shareholders disposing of shares
at that time may recognize a capital loss. Distributions, including
distributions reinvested in additional shares of the Trust, will nonetheless be
fully taxable, even if the number of shares in shareholders' accounts has been
reduced as described above.
    
 
   
     Ordinary income dividends paid by the Trust to shareholders who are
nonresident aliens or foreign entities will be subject to a 30% United States
withholding tax under existing provisions of the Code applicable to foreign
individuals and entities unless a reduced rate of withholding or a withholding
exemption is provided under applicable treaty law. Nonresident shareholders are
urged to consult their own tax advisors concerning the applicability of the
United States withholding tax.
    
 
     Dividends and interest received by the Trust 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.
 
   
     Under certain provisions of the Code, some shareholders may be subject to a
31% withholding tax on ordinary income dividends, capital gain dividends and
redemption payments ("backup withholding"). Generally, shareholders subject to
backup withholding will be those for whom no certified taxpayer identification
number is on file with the Trust or who, to the Trust's knowledge, have
furnished an incorrect number. When establishing an account, an investor must
certify under penalty of perjury that such number is correct and that such
investor is not otherwise subject to backup withholding.
    
 
     The foregoing is a general and abbreviated summary of the applicable
provisions of the Code and Treasury regulations presently in effect. For the
complete provisions, reference should be made to the
 
                                       16
<PAGE>   19
 
pertinent Code sections and the Treasury regulations promulgated thereunder. The
Code and the Treasury regulations are subject to change by legislative or
administrative action either prospectively or retroactively.
 
   
     Ordinary income and capital gain dividends may also be subject to state and
local taxes.
    
 
   
     Certain states exempt from state income taxation dividends paid by RICs
which are derived from interest on U.S. Government obligations. State law varies
as to whether and what percentage of dividend income attributable to U.S.
Government obligations is exempt from state income tax.
    
 
     Shareholders are urged to consult their own tax advisors regarding specific
questions as to Federal, foreign, state or local taxes. Foreign investors should
consider applicable foreign taxes in their evaluation of an investment in the
Trust.
 
ORGANIZATION OF THE TRUST
 
     The Trust was organized on May 14, 1987 under the laws of the Commonwealth
of Massachusetts. The Trust is a successor to a Massachusetts business trust of
the same name organized on January 21, 1975. It is a no-load, diversified,
open-end investment company. The Declaration of Trust permits the Trustees to
issue an unlimited number of full and fractional shares of beneficial interest
of a single class. Upon liquidation of the Trust, shareholders are entitled to
share pro rata in the net assets of the Trust available for distribution to
shareholders. Shares are fully paid and nonassessable by the Trust. Shareholders
are entitled to one vote for each full share held and fractional votes for
fractional shares held and vote in the election of the Trustees and on other
matters submitted to the vote of shareholders.
 
     The Declaration does not require that the Trust hold an annual meeting of
shareholders. However, the Trust will be required to call special meetings of
shareholders in accordance with the requirements of the Investment Company Act
to seek approval of new management and advisory arrangements, of a material
increase in distribution fees or of a change in the fundamental policies,
objectives or restrictions of the Trust. The Trust also would be required to
hold a special shareholders' meeting to elect new Trustees at such time as less
than a majority of the Trustees holding office have been elected by
shareholders. The Declaration provides that a shareholders' meeting may be
called for any reason at the request of 10% of the outstanding shares of the
Trust or by a majority of the Trustees. Except as set forth above, the Trustees
shall continue to hold office and appoint successor Trustees.
 
SHAREHOLDER REPORTS
 
     Only one copy of each shareholder report and certain shareholder
communications will be mailed to each identified shareholder regardless of the
number of accounts such shareholder has. If a shareholder wishes to receive
separate copies of each report and communication for each of the shareholder's
related accounts the shareholder should notify in writing:
 
           Financial Data Services, Inc.
           Attn: Document Evaluation Unit
           P.O. Box 45290
           Jacksonville, FL 32232-5290
 
     The written notification should include the shareholder's name, address,
tax identification number and Merrill Lynch and/or mutual fund account numbers.
If you have any questions regarding this please call your Merrill Lynch
financial consultant or Financial Data Services, Inc. at 800-221-7210.

the Declaration collectively as Trustees, but not as individuals or personally;
and no Trustee, shareholder, officer, employee or agent of the Trust shall be
held to any personal liability, nor shall resort be had to their private
property for the satisfaction of any obligation or claim of said Trust but the
"Trust Property" only shall be liable.

  7.   OTHER INFORMATION
    
 
This application enables you to take advantage of any or all of the optional
services available to Merrill Lynch Ready Assets Trust shareholders and will
update any options in effect for your account.
 
    If you select the Check Redemption Privilege, a supply of checks imprinted
with your name and shareholder account number will be sent to you in
approximately 10 days. You should be certain that a sufficient number of shares
are held by Transfer Agent for your account to cover the amount of any check or
ACH debit drawn by you. If insufficient shares are in the account, the check
will be returned or the ACH debit will be dishonored marked insufficient funds.
Since the dollar value of your account is constantly changing, the total value
of your account cannot be determined in advance and the account cannot be
entirely redeemed by check or ACH debit. If the Check Redemption Privilege is
being requested for an account in the name of a corporation or other
institution, the following additional documents must be submitted with this
authorization.
 
    CORPORATIONS--"Certification of Corporate Resolution," indicating the names
and titles of officers authorized to write checks or draw ACH debits, must be
signed by an officer other than one empowered to execute transactions, with his
signature guaranteed and the corporate seal affixed.
 
    PARTNERSHIPS--"Certification of Partnership," naming the partners and the
required number that may act in accordance with the terms of the Partnership
Agreement is to be executed by a general partner with his signature guaranteed.
 
    TRUSTS--"Certification of Trustees," naming the trustees and the required
number that may act in accordance with the terms of the Trust Agreement, must be
executed by a certifying trustee with his signature guaranteed and under the
corporate seal.
 
If you are adding or reinstating the Federal Funds Redemption option, the
signature(s) must be guaranteed in the space provided below. Your signature(s)
must be guaranteed by a commercial bank (not a savings bank) in New York City or
one having a New York City correspondent, or by a member firm of any national
securities exchange. (A Notary Public's seal does not constitute a signature
guarantee.)

Under penalty of perjury, I certify (1) that the number set forth above is my
correct Social Security Number or Taxpayer Identification Number and (2) that I
am not subject to backup withholding (as discussed under "Additional

thereto as a result of failure to report all interest and dividends, or the
Internal Revenue Service ("IRS") has notified me that I am no longer subject
thereto. Instructions: You must strike out the language in (2) above if you have
been notified that you are subject to backup withholding due to underreporting
and you have not received a notice from the IRS that backup withholding has been
terminated. By your signature below, you authorize the furnishing of this
certification to other Merrill Lynch-sponsored mutual funds.

                            ------------------------
 
     The Trust is a no-load money market fund, organized as a Massachusetts
business trust, seeking preservation of capital, liquidity and the highest
possible current income consistent with the foregoing objectives available from
investing in a diversified portfolio of short-term money market securities.
Portfolio securities principally consist of short-term United States Government
securities, Government agency securities, bank money instruments, corporate debt
instruments, including commercial paper and variable amount master demand notes,
and repurchase and reverse repurchase agreements. The Trust shares common goals
with those investors seeking to put reserve assets to work in an income
producing and prudent manner and to make these assets readily available without
penalty. There can be no assurance that the investment objectives of the Trust
will be realized. The Trust pays Merrill Lynch, Pierce, Fenner & Smith
Incorporated a distribution fee for providing certain services in connection
with the distribution of Trust shares. See "Purchase of Shares".

                       INVESTMENT OBJECTIVES AND POLICIES
 
     The investment objectives of the Trust are to seek preservation of capital,
liquidity and the highest possible current income consistent with these
objectives available from investing in a diversified portfolio of short-term
money market securities. Reference is made to "Investment Objectives and
Policies" in the Prospectus for a discussion of the investment objectives and
policies of the Trust.
 
   
     As discussed in the Prospectus, the Trust may invest in U.S.
dollar-denominated obligations of U.S. and foreign depository institutions,
including commercial and savings banks and savings and loan associations. The
obligations may be issued by U.S. or foreign depository institutions, foreign
branches or subsidiaries of U.S. depository institutions ("Eurodollar"
obligations), U.S. branches or subsidiaries of foreign depository institutions
("Yankeedollar" obligations) or foreign branches or subsidiaries of foreign
depository institutions. Obligations of foreign depository institutions, their
branches and subsidiaries, and Eurodollar and Yankeedollar obligations may
involve additional investment risks to the risks of obligations of U.S.
institutions. Such investment risks include adverse political and economic
developments, the possible imposition of withholding taxes on interest income
payable on such obligations, the possible seizure or nationalization of foreign
deposits and the possible establishment of exchange controls or other foreign
governmental laws or restrictions which might adversely affect the payment of
principal and interest. Generally, the issuers of such obligations are subject
to fewer regulatory requirements than are applicable to U.S. banks. Foreign
depository institutions, their branches or subsidiaries, and foreign branches or
subsidiaries of U.S. banks may be subject to less stringent reserve requirements
than U.S. banks. U.S. branches or subsidiaries of foreign banks are subject to
the reserve requirements of the state in which they are located. There may be
less publicly available information about a foreign bank or a branch or
subsidiary of a foreign bank than about a U.S. institution, and such branches or
subsidiaries may not be subject to the same accounting, auditing and financial
record keeping standards and requirements as U.S. banks. Evidence of ownership
of foreign depository and Eurodollar obligations may be held outside of the
United States and the Trust may be subject to the risks associated with the
holding of such property overseas. Foreign depository and Eurodollar obligations
of the Trust held overseas will be held by foreign branches of the Custodian for
the Trust's portfolio securities or by other U.S. or foreign banks under
subcustodian arrangements complying with the requirements of the Investment
Company Act of 1940 (the "Investment Company Act"). The Trust's manager, Merrill
Lynch Asset Management, L.P. (the "Manager"), will consider the above factors in
making investments in foreign depository, Eurodollar and Yankeedollar
obligations and will not knowingly purchase obligations which, at the time of
purchase, are subject to exchange controls or withholding taxes. Generally, the
Trust will limit its foreign depository and Yankeedollar investments to
obligations of banks organized in Canada, France, Germany, Japan, the
Netherlands, Switzerland, the United Kingdom and other western industrialized
nations. As discussed in the Prospectus, the Trust may also invest in U.S.
dollar-denominated commercial paper and other short-term obligations issued by
foreign entities. Such investments are subject to quality standards similar to
those applicable to investments in comparable obligations of domestic issuers.
Investments in foreign entities in general involve the same risks as those
described above in connection with investments in Eurodollar and Yankeedollar
obligations and obligations of foreign depository institutions and their foreign
branches and subsidiaries.
    
 
     Also as discussed in the Prospectus, the Trust may invest in money market
securities pursuant to repurchase agreements or purchase and sale contracts.
Repurchase agreements and purchase and sale contracts may be entered into only
with a member bank of the Federal Reserve System or primary dealer in U.S.
Government securities. Under such agreements, the bank or primary dealer agrees,
on 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
 
                                        2
<PAGE>   29
 
during such period. In the case of repurchase agreements, the prices at which
the trades are conducted do not reflect accrued interest on the underlying
obligation; whereas, in the case of purchase and sale contracts, the prices take
into account accrued interest. 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. In the case of a repurchase agreement, the Trust 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; the Trust does not have the right to seek additional collateral in
the case of purchase and sale contracts. 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 Trust but only constitute collateral
for the seller's obligation to pay the repurchase price. Therefore, the Trust
may suffer time delays and incur costs or possible losses in connection with the
disposition of the collateral. A purchase and sale contract differs from a
conventional repurchase agreement in that the contract arrangements stipulate
that the securities are owned by the Trust and, if the seller should fail to
repurchase the security, the Trust retains ownership of the security. The Trust
would also retain ownership of the securities in the event of a default under a
repurchase agreement that is construed not to be a collateralized loan. In the
event of a default under such a repurchase agreement or under a purchase and
sale contract, instead of the contractual fixed rate of return, the rate of
return to the Trust shall be dependent on intervening fluctuations of the market
value of such security and accrued interest on the security. In such event, the
Trust 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. 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, although they are considered repurchase
agreements for purposes of the Investment Company Act.
 
     The Trust's investments in short-term corporate debt and bank money
instruments will be rated, or will be issued by issuers who have been rated, in
one of the two highest rating categories for short-term debt obligations by a
nationally recognized statistical rating organization (an "NRSRO") or, if not
rated, will be of comparable quality as determined by the Trustees of the Trust.
The Trust's investments in corporate bonds and debentures (which must have
maturities at the date of purchase of 397 days (13 months) or less) will be in
issuers who have received from an NRSRO a rating with respect to a class of
short-term debt obligations that is comparable in priority and security with the
investment in one of the two highest rating categories for short-term
obligations or if not rated, will be of comparable quality as determined by the
Trustees of the Trust. Currently, there are six NRSROs: Duff and Phelps Inc.,
Fitch Investors Services, Inc., IBCA Limited and its affiliate IBCA Inc.,
Thompson BankWatch, Inc., Moody's Investors Service Inc., and Standard & Poor's
Corporation. See "Appendix--Description of Commercial Paper, Bank Money
Instruments and Corporate Bond Ratings".
 
     In addition to the investment restrictions set forth in the Prospectus, the
Trust has adopted the following restrictions and policies relating to the
investment of its assets and its activities, which are fundamental policies and
may not be changed without the approval of the holders of a majority of the
Trust's outstanding voting securities (which for this purpose 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). The Trust may not (1) make investments for the purpose of exercising
control or management; (2) purchase securities of other investment companies,
except in connection with a merger, consolidation, acquisition or
reorganization; (3) purchase or sell real estate (other than money market
securities secured by real estate or interests therein or money market
securities issued by companies which invest in real estate, or interests
therein), commodities or commodity contracts, interests in oil, gas or other
mineral exploration or
 
                                        3

development programs; (4) purchase any securities on margin, except for use of
short-term credit necessary for clearance of purchases and sales of portfolio
securities; (5) make short sales of securities or maintain a short position or
write, purchase or sell puts, calls, straddles, spreads or combinations thereof;
(6) make loans to other persons, provided that the Trust may purchase money
market securities or enter into repurchase agreements or purchase and sale
contracts and lend securities owned or held by it pursuant to (7) below; (7)
lend its portfolio securities in excess of 20% of its total assets, taken at
market value, provided that such loans are made according to the guidelines of
the Securities and Exchange Commission and the Trust's Board of Trustees,
including maintaining collateral from the borrower equal at all times to the
current market value of the securities loaned; (8) borrow amounts in excess of
20% of its total assets, taken at market value, and then only from banks as a
temporary measure for extraordinary or emergency purposes (the borrowing
provisions shall not apply to reverse repurchase agreements with respect to
which see (12) below) [usually only "leveraged" investment companies may borrow
in excess of 5% of their assets; however, the Trust will not borrow to increase
income but only to meet redemption requests which might otherwise require
untimely dispositions of portfolio securities; interest paid on such borrowings
will reduce net income]; (9) mortgage, pledge, hypothecate or in any manner
transfer (except as provided in (7) above), as security for indebtedness any
securities owned or held by the Trust except as may be necessary in connection
with borrowings mentioned in (8) above, and then such mortgaging, pledging or
hypothecating may not exceed 25% of the Trust's total assets, taken at market
value [although the Trust has the authority to mortgage, pledge or hypothecate
up to 25% of total assets under this investment restriction (9), as a matter of
operating policy, it will not mortgage, pledge or hypothecate in excess of 10%
of net assets in order to comply with the requirements of certain state
securities commissions]; (10) invest in securities (except for repurchase
agreements, purchase and sale contracts or variable amount master demand notes)
with legal or contractual restrictions on resale or for which no readily
available market exists or in securities of issuers (other than issuers of
Government agency securities) having a record, together with predecessors, of
less than three years of continuous operation if, regarding all such securities,
more than 5% of its total assets, taken at market value, would be invested in
such securities; (11) act as an underwriter of securities; (12) enter into
reverse repurchase agreements if, as a result thereof, the Trust's obligations
with respect to reverse repurchase agreements would exceed one-third of the
Trust's net assets (defined to be total assets, taken at market value, less
liabilities other than reverse repurchase agreements). The Trust will not
purchase securities while borrowings described in investment restriction (8) are
outstanding except to honor prior commitments.
 
     Lending of Portfolio Securities.  Subject to investment restriction (7)
above, the Trust may from time to time loan securities from its portfolio to
brokers, dealers and financial institutions and receive collateral in cash or
cash equivalents which will be maintained at all times in an amount equal to at
least 100% of the current market value of the loaned securities. Such collateral
will be invested in short-term securities, the income from which will increase
the return to the Trust. The Trust will retain all rights of beneficial
ownership as to the loaned portfolio securities, including voting rights and
rights to interest or other distributions, and will have the right to regain
record ownership of loaned securities to exercise such beneficial rights. Such
loans will be terminable at any time. The Trust may pay reasonable fees to
persons unaffiliated with the Trust in connection with the arranging of such
loans.

MANAGEMENT AND ADVISORY ARRANGEMENTS
 
     Reference is made to "Management of the Trust--Management and Advisory
Arrangements" in the Prospectus for certain information concerning management
and advisory arrangements of the Trust.
 
     Subject to the direction of the Board of Trustees, the Manager is
responsible for the actual management of the Trust's portfolio and constantly
reviews the Trust's holdings in light of its own research analysis and that from
other relevant sources. The responsibility for making decisions to buy, sell or
hold a particular security rests with the Manager. The Manager performs certain
of the other administrative services and provides all the office space,
facilities, equipment and necessary personnel for portfolio management of the
Trust.
 
   
     The Manager has access to the expertise of its affiliate, Merrill Lynch
Government Securities Inc. ("GSI"), which is a wholly-owned subsidiary of ML &
Co. In terms of dollar volume of trading, GSI is one of the largest dealers in
United States Government securities and Government agency securities, acting
both as a primary dealer and a secondary market trader. GSI is one of the
reporting dealers in Government securities who report their daily position and
activity to the Federal Reserve Bank of New York. A subsidiary of GSI acts as a
dealer in other money market securities including bankers' acceptances,
certificates of deposit and commercial paper. In addition, the total securities
and economic research facilities of Merrill Lynch are available to the Manager.
    
 
   
     Securities held by the Trust also may be held by, or be appropriate

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 Trust or other advisory clients arise
for consideration at or about the same time, transactions in such securities
will be made, insofar as feasible, for the respective funds and clients in a
manner deemed equitable to all. To the extent that transactions on behalf of
more than one client of the Manager or its subsidiary 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.
 
     As compensation for its services to the Trust, the Manager receives a fee
from the Trust at the end of each month at the following annual rates:

     The Manager is obligated to reimburse the Trust to the extent that the
Trust's ordinary operating expenses exceed 2.5% of the first $30 million of
average daily net assets, 2.0% of the next $70 million of average daily net
assets and 1.5% of the average daily net assets in excess thereof. Expenses
which are not subject to this limitation are interest, taxes, brokerage
commissions and extraordinary items such as litigation costs. The obligation of
the Manager to reimburse the Trust under this limitation is not limited to the
amount of the management fee. Prior to September 21, 1989, the Trust was subject
to more restrictive expense limitation provisions. For the fiscal years ended
December 31, 1991, 1992 and 1993, the total management fees paid by the Trust to
the Manager aggregated $34,720,600, $29,798,649 and $25,841,742, respectively.
    
 
   
     The Manager is obligated to provide investment advisory services, to
furnish administrative services, office space and facilities for management of
the Trust's affairs, to pay all compensation of officers of the Trust as well as
all Trustees of the Trust who are affiliated persons of ML & Co. and its
subsidiaries, and to bear the costs and expenses of advertising of the Trust.
The Trust pays all other expenses incurred in the operation of the Trust (except
for certain expenses incurred by the Distributor--see "Purchase of Shares"),
including, among other things, taxes, expenses for legal, auditing and
accounting services, allocated portions of clerical salaries related to Trust
activities, costs of printing of prospectuses and statements of additional
information (to the extent not paid by the Distributor), shareholder reports and
proxy statements, charges of the custodian and transfer agent, expenses of
redemption of shares, expenses of registering and qualifying shares for sale
under Federal, state and other laws, costs of conducting shareholder relations,
fees and actual out-of-pocket expenses of unaffiliated Trustees, interest,
brokerage costs and other expenses properly payable by the Trust. Accounting
services are provided to the Trust by the Manager, and the Trust reimburses the
Manager for its costs in connection with such services. For the fiscal year
ended December 31, 1993, $274,854 was required to be reimbursed.

     Duration and Termination.  Unless earlier terminated as described below,
the Management Agreement will continue in effect from year to year if approved
annually (a) by the Trustees of the Trust or by a majority of the outstanding
voting shares of the Trust and (b) by a majority of Trustees who are not parties
to such contract or interested persons (as defined in the Investment Company
Act) of any such party. Such contract is not assignable and may be terminated
without penalty on 60 days' written notice at the option of either party thereto
or by the vote of the shareholders of the Trust.
 
                               PURCHASE OF SHARES
 
     Reference is made to "Purchase of Shares" in the Prospectus for certain
information as to the purchase of Trust shares.
 
     The Trust is offering its shares without sales charge at a public offering
price equal to the net asset value next determined after a purchase order
becomes effective. Share purchase orders are effective on the day Federal Funds
become available to the Trust. The Trustees anticipate that the net asset value
will remain constant at $1.00 per share and that fluctuations in value will be
reflected in the number of outstanding shares in the shareholder's account
rather than in the per share dollar value. See "Determination of Net Asset
Value". The minimum initial purchase is $5,000. The minimum subsequent purchase
is $1,000. The minimum initial purchase with respect to pension, profit sharing,
individual retirement and other retirement plans is $250 and there is no minimum
applicable with respect to subsequent investments in connection with such plans.
For accounts advised by banks and registered investment advisers, including the
Manager, the minimum initial purchase is $300 and the minimum subsequent
purchase is $100. Any order may be rejected by the Distributor or the Trust.
 
     The Distributor acts as the distributor in the continuous offering of the
Trust's shares. Shares may be purchased directly from the Distributor or from
other securities dealers, including Merrill Lynch, with whom the Distributor has
entered into a selected dealer agreement. Securities dealers may charge
investors a fee in connection with such transactions. Merrill Lynch has informed
the Trust that it does not charge such a fee.
 
     The Trust's distribution agreement with the Distributor is renewable
annually, and may be terminated upon 60 days' written notice by either party.
Under such agreement, after the prospectuses, statements of additional
information and periodic reports have been prepared and set in type, the
Distributor will pay for the printing and distribution of copies thereof used in
connection with the offering to dealers and investors. The Distributor also will
pay for other supplementary sales literature.
 
     It is the Trust's policy to be invested as fully as reasonably practicable
at all times to maximize the yield on the Trust's portfolio. The money markets
in which the Trust will purchase and sell portfolio securities normally require
immediate settlement of transactions in Federal Funds. Federal Funds are a
commercial bank's deposits in a Federal Reserve Bank and can be transferred from
one member bank's account to that of another member bank on the same day and
thus are considered to be immediately available funds. Orders for the purchase
of Trust shares shall become effective on the day Federal Funds become available
to the Trust and the shares being purchased will be issued at the net asset
value per share next determined. If Federal Funds are available to the Trust
prior to 4:00 P.M., New York time, on any business day, the order will be
effective on that day. Shares purchased will begin accruing dividends on the day
following the date of purchase.

DISTRIBUTION PLAN
 
     The Trust has adopted a Shareholder Servicing Plan and Agreement (the
"Plan") in compliance with Rule 12b-1 under the Investment Company Act pursuant
to which the Trust is authorized to pay Merrill Lynch a fee at the annual rate
of 0.125% of average daily net asset value of Trust accounts maintained through
Merrill Lynch. The Plan reimburses Merrill Lynch only for actual expenses
incurred in the fiscal year in which the fee is paid. The fee is principally to
provide compensation to Merrill Lynch financial consultants and other Merrill
Lynch personnel for providing direct personal services to shareholders of the
Trust. Under the Plan, as amended to date, Merrill Lynch, in its sole
discretion, may expend out of the fee an amount not exceeding 0.01% of the
average daily net asset value as reimbursement for expenditures incurred in
advertising activities promoting the sale, marketing and distribution of the
shares of the Trust.
 
   
     The Trustees believe that the Trust's expenditures under the Plan benefit
the Trust and its shareholders by providing better shareholder services and by
affecting positively the sale and distribution of Trust shares. For the fiscal
years ended December 31, 1991, 1992 and 1993, $11,732,371, $9,900,529 and
$8,501,923, respectively, was paid to Merrill Lynch pursuant to the Plan. All of
the amounts expended for the years ended December 31, 1991, 1992 and 1993 were
allocated to Merrill Lynch financial consultants, other Merrill Lynch personnel
and related administrative costs.
    
 
     Among other things, the Plan provides that Merrill Lynch shall provide and
the Trustees of the Trust shall review quarterly reports of the expenditures
made by Merrill Lynch pursuant to the Plan. In their consideration of the Plan,
the Trustees must consider all factors they deem relevant, including information
as to the benefits of the Plan to the Trust and its shareholders. The Plan
further provides that, so long as the Plan remains in effect, the selection and
nomination of Trustees of the Trust who are not "interested persons" of the
Trust as defined in the Investment Company Act (the "Independent Trustees")
shall be committed to the discretion of the Independent Trustees then in office.
The 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 voting securities of the Trust. Finally, the Plan cannot be
amended to increase materially the amount to be spent by the Trust thereunder
without shareholder approval, and all material amendments are required to be
approved by vote of the Trustees of the Trust, including a majority of the
Independent Trustees, cast in person at a meeting called for that purpose.
 
                              REDEMPTION OF SHARES
 
     Reference is made to "Redemption of Shares" in the Prospectus for certain
information as to the repurchase and redemption of Trust shares.
 
     The right to redeem shares or to receive payment with respect to any such
redemption may be suspended for a period of up to seven days. Suspensions of
more than seven days may not be made except (1) for any period (A) during which
the New York Stock Exchange is closed other than customary weekend and holiday
closings or (B) during which trading on the New York Stock Exchange is
restricted; (2) for any period during which an emergency exists as a result of
which (A) disposal by the Trust of securities owned by it is not reasonably
practicable or (B) it is not reasonably practicable for the Trust fairly to
determine the value of its net assets; or (3) for such other periods as the
Securities and Exchange Commission may by order permit for the protection of
security holders of the Trust. The Commission shall by rules and regulations
determine the conditions under which (i) trading shall be deemed to be
restricted and (ii) an emergency shall be deemed to exist within the meaning of
clause (2) above.
 
                                        9
<PAGE>   36
 
     The total value of the shareholder's investment at the time of redemption
may be more or less than his cost, depending on the market value of the
securities held by the Trust at such time and income earned.
 
                             PORTFOLIO TRANSACTIONS
 
     The Trust has no obligation to deal with any dealer or group of dealers in
the execution of transactions in portfolio securities. Subject to policy
established by the Trustees and officers of the Trust, the Manager is primarily
responsible for the Trust's portfolio decisions and the placing of the Trust's
portfolio transactions. In placing orders, it is the policy of the Trust 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, and the
firm's risk in positioning the securities involved. While the Manager generally
seeks reasonably competitive spreads or commissions, the Trust will not
necessarily be paying the lowest spread or commission available. The Trust's
policy of investing in securities with short maturities will result in high
portfolio turnover.
 
     The money market securities in which the Trust invests are traded primarily
in the over-the-counter market. Bonds and debentures usually are traded
over-the-counter, but may be traded on an exchange. Where possible, the Trust
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. Money market
securities generally are traded on a net basis and normally do not involve
either brokerage commissions or transfer taxes. The cost of executing portfolio
securities transactions of the Trust will consist primarily of dealer spreads
and underwriting commissions. Under the Investment Company Act, persons
affiliated with the Trust are prohibited from dealing with the Trust as a
principal in the purchase and sale of securities unless an exemptive order
allowing such transactions is obtained from the Securities and Exchange
Commission. Since over-the-counter transactions usually are principal
transactions, affiliated persons of the Trust, including Merrill Lynch
Government Securities Inc. ("GSI") and Merrill Lynch, may not serve as the
Trust's dealer in connection with such transactions except pursuant to the
exemptive orders described below. However, affiliated persons of the Trust may
serve as its broker in over-the-counter transactions conducted on an agency
basis.
 
   
     The Securities and Exchange Commission has issued an exemptive order
permitting the Trust to conduct principal transactions with GSI in United States
Government and Government agency securities and with a subsidiary of GSI in
certificates of deposit and other short-term money instruments and commercial
paper. This order contains a number of conditions, including conditions designed
to ensure that the price to the Trust from GSI or its subsidiary is equal to or
better than that available from other sources. GSI and its subsidiary have
informed the Trust that they will in no way, at any time, attempt to influence
or control the activities of the Trust or the Manager in placing such principal
transactions. The exemptive order allows GSI or its subsidiary, Merrill Lynch
Money Markets Inc., to receive a dealer spread on any transaction with the Trust
no greater than their customary dealer spread for transactions of the type
involved. Generally, such spreads do not exceed 0.25% of the principal amount of
the securities involved. During the fiscal year ended December 31, 1991, the
Trust engaged in 154 such transactions aggregating approximately $4.2 billion.
During the fiscal year ended December 31, 1992, the Trust engaged in 206 such
transactions aggregating approximately $5.1 billion. During the fiscal year
ended December 1993, the Trust engaged in 152 such transactions aggregating
approximately $5.6 billion.
    
 
   
     The Trustees of the Trust have considered the possibilities of recapturing
for the benefit of the Trust expenses of possible portfolio transactions, such
as dealer spreads and underwriting commissions, by
    
 
                                       10
<PAGE>   37
 
conducting such portfolio transactions through affiliated entities, including
GSI and Merrill Lynch. For example, dealer spreads received by GSI or its
subsidiary on transactions conducted pursuant to the permissive orders described
above could be offset against the management fee payable by the Trust to the
Manager. After considering all factors deemed relevant, the Trustees made a
determination not to seek such recapture. The Trustees will reconsider this
matter from time to time.
 
     The Trust does not expect to use one particular dealer, but, subject to
obtaining the best price and execution, dealers who provide supplemental
investment research (such as economic data and market forecasts) to the Manager
may receive orders for transactions by the Trust. Information so received will
be in addition to and not in lieu of the services required to be performed by
the Manager under its Management Agreement and the expenses of the Manager will
not necessarily be reduced as a result of the receipt of such supplemental
information.
 
                        DETERMINATION OF NET ASSET VALUE
 
   
     The net asset value of the shares of the Trust is determined by the Manager
once daily, immediately after the daily declaration of dividends, as of 4:00
P.M., New York time, on each day the New York Stock Exchange or New York banks
are open for business. As a result of this procedure, the net asset value is
determined each day except for days on which both the New York Stock Exchange
and New York banks are closed. Both the New York Stock Exchange and New York
banks are closed on New Year's Day, Presidents' Day, Memorial Day, Independence
Day, Labor Day, Thanksgiving Day and Christmas Day. The net asset value per
share is computed pursuant to the "penny-rounding" method by dividing the value
of the securities held by the Trust plus any cash or other assets (including
interest accrued but not yet received) minus all liabilities (including accrued
expenses) by the total number of shares outstanding at such time. Expenses,
including the fees payable to the Manager, are accrued daily.
    
 
   
     The Trust values its portfolio securities with remaining maturities of 60
days or less on an amortized cost basis and values its securities with remaining
maturities of greater than 60 days for which market quotations are readily
available at market value. Other securities held by the Trust are valued at
their fair value as determined in good faith by or under the direction of the
Board of Trustees.
    
 
   
     In accordance with the Securities and Exchange Commission rule applicable
to the valuation of its portfolio securities, the Trust will maintain a
dollar-weighted average portfolio maturity of 90 days or less and will purchase
instruments having remaining maturities of not more than 397 days (13 months),
with the exception of U.S. Government and U.S. Government agency securities,
which may have remaining maturities of up to 762 days (twenty-five months). The
Trust will invest only in securities determined by the Trustees to be of high
quality with minimal credit risks. In addition, the Trustees have established
procedures designed to stabilize, to the extent reasonably possible, the Trust's
price per share as computed for the purposes of sales and redemptions at $1.00.
Deviations of more than an insignificant amount between the net asset value
calculated using market quotations and that calculated on a "penny-rounded"
basis will be reported to the Trustees by the Manager. In the event the Trustees
determine that a deviation exists which may result in the material dilution or
other unfair results to investors or existing shareholders, the Trust will take
such corrective action as it regards as necessary and appropriate, including the
reduction of the number of outstanding shares of the Trust by having each
shareholder proportionately contribute shares to the Trust's capital; the sale
of portfolio instruments prior to maturity to realize capital gains or losses or
to shorten average portfolio maturity; withholding dividends; or establishing a
net asset value per share solely by using available market quotations. If the
number of outstanding shares is reduced in order to maintain a constant net
asset value of $1.00 per share, the shareholders will contribute proportionately
to the Trust's capital the number of shares which
    
 
                                       11
<PAGE>   38
 
   
represents their proportionate shares of the difference between the portfolio's
fair market value and net asset value based on $1.00 per share. Each shareholder
will be deemed to have agreed to such contribution by an investment in the
Trust.
    
 
   
     Since the net income of the Trust (including realized gains and losses on
the portfolio securities) is determined and declared as a dividend immediately
prior to each time the net income of the Trust is determined, the net asset
value per share of the Trust normally remains at $1.00 per share immediately
after each such determination and dividend declaration. Any increase in the
value of a shareholder's investment in the Trust, representing the reinvestment
of dividend income, is reflected by an increase in the number of shares of the
Trust in the account and any decrease in the value of a shareholder's investment
may be reflected by a decrease in the number of shares in the account. (See
"Taxes".)
    
 
   
                               YIELD INFORMATION
    
 
     The Trust normally computes its annualized yield by determining the net
income for a seven-day base period for a hypothetical pre-existing account
having a balance of one share at the beginning of the base period, dividing the
net income by the net asset value of the account at the beginning of the base
period to obtain the base period return, multiplying the result by 365 and then
dividing by seven. Under this calculation, the yield reflects realized gains and
losses on portfolio securities. In accordance with regulations adopted by the
Securities and Exchange Commission, the Trust is required to disclose its
annualized yield for certain seven-day base periods in a standardized manner
which does not take into consideration any realized or unrealized gains or
losses on portfolio securities. The Securities and Exchange Commission also
permits the calculation of a standardized effective or compounded yield. This is
computed by compounding the unannualized base period return which is done by
adding one to the base period return, raising the sum to a power equal to 365
divided by seven, and subtracting one from the result. This compounded yield
calculation also excludes realized and unrealized gains or losses on portfolio
securities.
 
                              SHAREHOLDER SERVICES
 
     The Trust offers a number of shareholder services described below designed
to facilitate investment in its shares. Full details as to each of such services
and copies of the various plans described below and instructions as to how to
participate in the various services or plans, or to change options with respect
thereto, can be obtained from the Trust, the Distributor or Merrill Lynch.
 
INVESTMENT ACCOUNT
 
     Each shareholder whose account is maintained at the Transfer Agent has an
Investment Account and will receive monthly statements from the Transfer Agent
showing any activity in his account since the preceding statement. A shareholder
may make additions to his Investment Account at any time by purchasing shares at
the applicable public offering price either through his securities dealer, by
wire or by mail directly to the Transfer Agent, acting as agent for his dealer.
A shareholder may ascertain the number of shares in his Investment Account by
telephoning the Transfer Agent at (800) 221-7210 toll-free. The Transfer Agent
will furnish this information only after the shareholder has specified the name,
address, account number and social security number of the registered owner or
owners.
 
     In the interest of economy and convenience and because of the operating
procedures of the Trust, certificates representing the Trust's shares will not
be issued physically. Shares are maintained by the Trust on its register
maintained by the Transfer Agent and the holders thereof will have the same
rights and ownership with respect to such shares as if certificates had been
issued.
 
                                       12
<PAGE>   39
 
AUTOMATIC INVESTMENT PLAN
 
     The Trust offers an Automatic Investment Plan in connection with accounts
maintained at the Transfer Agent whereby the Transfer Agent is authorized
through preauthorized checks 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. See the Purchase Application in the
Prospectus. A shareholder's Automatic Investment Plan may be terminated at any
time without charge or penalty by the shareholder, the Trust, the Transfer Agent
or the Distributor.
 
ACCRUED MONTHLY PAYOUT PLAN
 
     The dividends of the Trust are reinvested automatically in additional
shares. Shareholders with accounts maintained at the Transfer Agent desiring
cash payments may enroll in the Accrued Monthly Payout Plan, under which shares
equal in number to shares credited through the automatic reinvestment of
dividends and distributions during each month are redeemed at net asset value on
the last Friday of such month in order to meet the monthly distribution.
Investors may open an Accrued Monthly Payout Plan by completing the appropriate
portion of the Purchase Application in the Prospectus. A shareholder's Accrued
Monthly Payout Plan may be terminated at any time without charge or penalty by
the shareholder, the Trust, the Transfer Agent or the Distributor.
 
SYSTEMATIC WITHDRAWAL PLANS
 
     A shareholder may elect to make systematic withdrawals from an Investment
Account on either a monthly or quarterly basis as provided below. Quarterly
withdrawals are available for shareholders who have acquired shares of the Trust
having a value, based on cost or the current offering price, of $5,000 or more,
and monthly withdrawals for shareholders with shares with such a value of
$10,000 or more. The quarterly periods end on the 24th day of March, June,
September and December. See the Purchase Application in the Prospectus.
 
     At the time of each withdrawal payment, sufficient 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 a dollar amount
or a percentage of the value of his shares. Redemptions will be made at net
asset value as determined at the close of business on the New York Stock
Exchange on the 24th day of each month or the 24th day of the last month of each
quarter, whichever is applicable. A shareholder's Systematic Withdrawal Plan may
be terminated at any time, without charge or penalty, by the shareholder, the
Trust, the Transfer Agent or the Distributor. A shareholder may not elect to
make systematic withdrawals while he is enrolled in the Accrued Monthly Payout
Plan.
 
     Withdrawal payments should not be considered as dividends, yield or income.
Withdrawals are sales of shares and may result in taxable gain or loss. If
periodic withdrawals continuously exceed reinvested dividends, the shareholder's
original investment will be reduced correspondingly. Shareholders are cautioned
not to designate withdrawal programs that result in an undue reduction of
principal. There are no minimums on amounts that may be systematically
withdrawn.
 
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
Trust and in 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
 
                                       13
<PAGE>   40
 
Merrill Lynch. In addition, eligible shareholders of the Trust may participate
in a variety of qualified employee benefit plans which are available from the
Distributor. Participants in these plans may invest in the Trust and in certain
other mutual funds sponsored by Merrill Lynch. Information with respect to these
plans is available upon request from the Distributor. See "Purchase of Shares"
in the Prospectus.
 
     Capital gains and income received in each of the plans referred to above
are exempt from Federal taxation until distributed from the plans. Investors
considering participation in any such plan should review specific tax laws
relating thereto and should consult their attorneys or tax advisers with respect
to the establishment and maintenance of any such plan.
 
EXCHANGE PRIVILEGE
 
     Shareholders of the Trust who have held all or part of their shares for at
least 15 days may exchange their shares of the Trust for Class A shares of the
mutual funds described below (collectively referred to as the "funds") on the
basis described below. Shares with a net asset value of at least $250 are
required to qualify for the exchange privilege. It is contemplated that the
exchange privilege may be applicable to other new mutual funds whose shares are
distributed by the Distributor. The exchange privilege available to participants
in the Merrill Lynch BlueprintSM Program may be different from that available to
other investors.
 
     Under the exchange privilege, each of the funds offers to exchange its
shares ("new shares") for shares ("outstanding shares") of any of the other
funds, on the basis of relative net asset value per share, plus an amount equal
to the difference, if any, between the sales charge previously paid on the
outstanding shares and the sales charge payable at the time of the exchange on
the new shares. At the present time, the shares of each of the funds are sold
with varying sales charges. With respect to outstanding shares as to which
previous exchanges have taken place, the "sales charge previously paid" shall
include the aggregate of the charges paid with respect to such shares in the
initial purchase and any subsequent exchange. Shares issued pursuant to dividend
reinvestment are sold on a no-load basis in each of the funds. For purposes of
the exchange privilege, dividend reinvestment shares shall be deemed to have
been sold with a sales charge equal to the sales charge previously paid on the
shares on which the dividend was paid. Based on this formula an exchange of
shares of the Trust, which are sold on a no-load basis, for shares of the other
funds, which are sold with a sales charge, generally will require the payment of
a sales charge.
 
     The investment objectives of the other funds into which exchanges can be
made are as follows:

     Before effecting an exchange, shareholders of the Trust 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 for Federal income
tax purposes and, depending on the circumstances, a short-or long-term capital
gain or loss may be realized. In addition, an exchanging shareholder of any of
the funds may be subject to backup withholding unless such shareholder certifies
under penalty of perjury that the taxpayer identification number on file with
any such fund is correct, and that such shareholder is not otherwise subject to
backup withholding. See "Taxes".
    
 
   
     To exercise the exchange privilege shareholders may either contact their
listed securities dealer, who will advise the Trust of the exchange, or write to
the Transfer Agent requesting that the exchange be effected. Such letter must be
signed exactly as the account is registered with the signatures guaranteed by a
national bank or member firm of any national or regional stock exchange.
Shareholders of the Trust, and shareholders of the other funds described above
with shares for which certificates have not been issued, may exercise the
exchange privilege by wire through their securities dealer. The Trust reserves
the right to require a properly completed Exchange Application. This exchange
privilege may be modified or terminated at any time in accordance with the rules
of the Securities and Exchange Commission. The Trust 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 at any time and may
thereafter resume such offering from time to time. The exchange privilege is
available only to U.S. shareholders in states where the exchange legally may be
made.

                                     TAXES
 
   
     The Trust 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"). If it so qualifies, the Trust (but not its
shareholders) will not be subject to Federal income tax on the part of its net
ordinary income and net realized capital gains which it distributes to
shareholders. The Trust intends to distribute substantially all of such income.
    
 
   
     Dividends paid by the Trust from its ordinary income and distributions of
the Trust's net realized short-term capital gains (together referred to
hereafter as "ordinary income dividends") are taxable to shareholders as
ordinary income for Federal income tax purposes. Distributions made from the
Trust's net realized long-term capital gains ("capital gain dividends") are
taxable to shareholders as long-term capital gains regardless of the length of
time the shareholder has owned Trust shares. Distributions in excess of the
Trust's earnings and profits will first reduce the adjusted tax basis of a
holder's shares and, after such adjusted tax basis is reduced to zero, will
constitute capital gains to such holder (assuming the shares are held as a
capital asset). Any loss upon the sale or exchange of Trust shares held for six
months or less will be treated as long-term capital loss to the extent of any
capital gain dividends received by the shareholder.
    
 
   
     Dividends are taxable to shareholders even though they are reinvested in
additional shares of the Trust. Not later than 60 days after the close of its
taxable year, the Trust will provide its shareholders with a written notice
designating the amounts of any ordinary income or capital gain dividends.
Distributions by the Trust, whether from ordinary income or capital gains, will
not be eligible for the dividends received deduction allowed to corporations
under the Code. If the Trust pays a dividend in January which was declared in
the previous October, November or December to shareholders of record on a
specified date in one of such months, then such dividend will be treated for tax
purposes as being paid by the Trust and received by its shareholders on December
31 of the year in which such dividend was declared.
    
 
   
     If the value of assets held by the Trust declines, the Board of Trustees
may authorize a reduction in the number of outstanding shares in shareholders'
accounts so as to preserve a net asset value of $1.00 per share. After such a
reduction, the basis of eliminated shares would be added to the basis of
shareholders' remaining Trust shares, and any shareholders disposing of shares
at that time may recognize a capital loss. Distributions, including
distributions reinvested in additional shares of the Trust, will nonetheless be
fully taxable, even if the number of shares in shareholders' accounts has been
reduced as described above.
    
 
   
     Ordinary income dividends paid by the Trust to shareholders who are
nonresident aliens or foreign entities will be subject to a 30% United States
withholding tax under existing provisions of the Code applicable to foreign
individuals and entities unless a reduced rate of withholding or a withholding
exemption is provided under applicable treaty law. Nonresident shareholders are
urged to consult their own tax advisers concerning the applicability of the
United States withholding tax.
    
 
     Dividends and interest received by the Trust 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.
 
   
     Under certain provisions of the Code, some shareholders may be subject to a
31% withholding tax on ordinary income dividends, capital gain dividends and
redemption payments ("backup withholding"). Generally, shareholders subject to
backup withholding will be those for whom no certified taxpayer identification
number is on file with the Trust or who, to the Trust's knowledge, have
furnished an incorrect number. When establishing an account, an investor must
certify under penalty of perjury that such number is correct and that such
investor is not otherwise subject to backup withholding.
    
 
                                       22
<PAGE>   49
 
   
     If a shareholder exercises the exchange privilege within 90 days of
acquiring the shares, then the loss the shareholder can recognize on the
exchange will be reduced (or the gain increased) to the extent the sales charge
paid to the Trust (including any sales charge paid with respect to shares that
were exchanged, within 90 days after being acquired, for shares of the Trust)
reduces any sales charge the shareholder would have owed upon purchase of the
new Class A shares in the absence of the exchange privilege. Instead, such sales
charge will be treated as an amount paid for the new Class A shares.
    
 
   
     The Code requires a RIC to pay a nondeductible 4% excise tax to the extent
the RIC does not distribute, during any calendar year, 98% of its ordinary
income, determined on a calendar year basis, and 98% of its capital gains,
determined, in general, on an October 31 year end, plus certain undistributed
amounts from previous years. While the Trust intends to distribute its income
and capital gains in a manner necessary to avoid imposition of the 4% excise
tax, there can be no assurance that sufficient amounts of the Trust's taxable
income and capital gains will be distributed to avoid entirely the imposition of
the tax. In such event, the Trust will be liable for the tax only on the amount
by which it does not meet the foregoing distribution requirements.
    
 
     The foregoing is a general and abbreviated summary of the applicable
provisions of the Code and Treasury regulations presently in effect. For the
complete provisions, reference should be made to the pertinent Code sections and
the Treasury regulations promulgated thereunder. The Code and the Treasury
regulations are subject to change by legislative or administrative action either
prospectively or retroactively.
 
   
     Ordinary income and capital gain dividends also may be subject to state and
local taxes.
    
 
     Certain states exempt from state income taxation dividends paid by RICs
which are derived in whole or in part from interest on U.S. Government
obligations. State law varies as to whether and what percentage of dividend
income attributable to U.S. Government obligations is exempt from state income
tax.
 
   
     Shareholders are urged to consult their tax advisors regarding specific
questions as to Federal, foreign, state or local taxes. Foreign investors should
consider applicable foreign taxes in their evaluation of an investment in the
Trust.
    
 
                              GENERAL INFORMATION
 
DESCRIPTION OF SHARES
 
     The Declaration of Trust of the Trust permits the Trustees to issue an
unlimited number of full and fractional shares of beneficial interest, par value
$.10 per share, of a single class and to divide or combine the shares into a
greater or lesser number of shares without thereby changing the proportionate
beneficial interests in the Trust. Each share represents an equal proportionate
interest in the Trust with each other share. Upon liquidation of the Trust,
shareholders are entitled to share pro rata in the net assets of the Trust
available for distribution to shareholders. Shares have no preemptive or
conversion rights. The rights of redemption are described elsewhere herein and
in the Prospectus. Shares are fully paid and nonassessable by the Trust.
 
     Shareholders are entitled to one vote for each full share held and
fractional votes for fractional shares held and vote in the election of
Trustees and on other matters submitted to the vote of shareholders. Voting
rights are not cumulative, so that the holders of more than 50% of the shares
voting in the election of Trustees can, if they choose to do so, elect all
Trustees of the Trust.  No amendment may be made to the Declaration of Trust
without the affirmative vote of a majority of the outstanding shares of the
Trust.

INDEPENDENT AUDITORS' REPORT
 
The Board of Trustees and Shareholders,
MERRILL LYNCH READY ASSETS TRUST:
 
   
We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Merrill Lynch Ready Assets Trust as of December
31, 1993, the related statements of operations for the year then ended, and
changes in net assets for each of the years in the two-year period then ended,
and the financial highlights for each of the years in the five-year period then
ended. These financial statements and the financial highlights are the
responsibility of the Trust's management. Our responsibility is to express an
opinion on these financial statements and the financial highlights based on our
audits.
    
 
   
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and the financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned at December
31, 1993 by correspondence with the custodian. An audit also includes assessing
the accounting principles used and significant estimates made by management, as
well as evaluating the overall financial statement presentation. We believe that
our audits provide a reasonable basis for our opinion.
    
 
   
In our opinion, such financial statements and financial highlights present
fairly, in all material respects, the financial position of Merrill Lynch Ready
Assets Trust as of December 31, 1993, the results of its operations, the changes
in its net assets, and the financial highlights for the respective stated
periods in conformity with generally accepted accounting principles.

Merrill Lynch Ready Assets Trust
Notes to Financial Statements.
 
1. Significant Accounting Policies: 
Merrill Lynch Ready Assets Trust (the "Trust") is registered under the 
Investment Company Act of 1940 as a diversified, open-end investment 
management company. The following is a summary of significant accounting 
policies followed by the Trust.

(a) Valuation of investments--Investments maturing more than sixty days 
after the valuation date are valued at the most recent bid price or yield 
equivalent as obtained from dealers that make markets in such securities. 
When such securities are valued with sixty days or less to maturity, the 
difference between the valuation existing on the sixty-first day before 
maturity and maturity value is amortized on a straight-line basis to 
maturity. Investments maturing within sixty days from their date of
acquisition are valued at amortized cost, which approximates market value. 
For purposes of valuation, the maturity of a variable rate security is 
deemed to be the next coupon date on which the interest rate is to be 
adjusted. 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.

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

(c) Security transactions and investment income--Security transactions are 
recorded on the dates the transactions are entered into (the trade dates). 
Interest income (including amortization of premium or discount) is recognized 
on the accrual basis. Realized gains and losses on security transactions 
are determined on the identified cost basis.

(d) Prepaid registration fees--Prepaid registration fees are charged to 
expense as the related shares are issued.

(e) Dividends to shareholders--The Trust declares dividends daily and 
reinvests such dividends daily (net of non-resident alien tax and back-up 
withholding tax) in additional shares of beneficial interest at net asset 
value. Dividends are declared from the total of net investment income and 
net realized gain or loss on investments.

2. Investment Advisory Agreement and Transactions with
Affiliates:
The Trust has entered into an Investment Advisory Agreement with Merrill 
Lynch Asset Management ("MLAM" or "Adviser"). MLAM is the name under which 
Merrill Lynch Investment Management, Inc. ("MLIM") does business. MLIM is 
an indirect wholly-owned subsidiary of Merrill Lynch & Co., Inc. The Trust 
has also entered into a Distribution Agreement and a Distribution Plan
with Merrill Lynch Funds Distributor, Inc. ("MLFD" or "Distributor"), a 
wholly-owned subsidiary of MLIM. MLAM provides the Trust with investment 
management, research, statistical, and advisory services, and pays certain 
other expenses of the Trust. For such services, the Trust pays a monthly 
fee based upon the average daily value of the Trust's net assets at the 
following annual rates:

Not exceeding $500 million                                     0.500%
In excess of $500 million but not exceeding $1 billion         0.400
In excess of $1 billion but not exceeding $5 billion           0.350
In excess of $5 billion but not exceeding $10 billion          0.325
In excess of $10 billion but not exceeding $15 billion         0.300
In excess of $15 billion but not exceeding $20 billion         0.275
In excess of $20 billion                                       0.250
</TABLE>

The most restrictive annual expense limitation requires that the Adviser 
reimburse the Trust to the extent the Trust's expenses (excluding interest,
taxes, distribution fees, brokerage fees and commissions, and extraordinary 
items) exceed 2.5% of the Trust's first $30 million of average daily net 
assets, 2.0% of the next $70 million of average daily net assets, and 1.5% 
of the average daily net assets in excess thereof. The obligation of the 
Adviser to reimburse the Trust under this limitation is not limited to the 
amount of the management fee.

Notes to Financial Statments (concluded)

Effective January 1, 1994, the investment advisory business of MLAM 
reorganized from a corporation to a limited partnership. The general 
partner of MLAM is Princeton Services, Inc., an indirect wholly-owned 
subsidiary of Merrill Lynch & Co.

The Trust has adopted a Shareholder Servicing Plan and Agreement in 
compliance with Rule 12b-1 under the Investment Company Act of 1940, 
pursuant to which Merrill Lynch, Pierce, Fenner and Smith Inc. ("MLPF&S"), 
a wholly-owned subsidiary of Merrill Lynch & Co., Inc., receives a fee each
month from the Trust at the annual rate of 0.125% of average daily net assets
of the accounts of Trust shareholders who maintain their Trust accounts through
MLPF&S. This fee is to compensate MLPF&S financial consultants and other 
directly involved branch office personnel for providing direct personal
services to shareholders. The fee is not compensation for administrative 
services.

Financial Data Services, Inc. ("FDS"), a wholly-owned subsidiary of Merrill
Lynch & Co., Inc., is the Trust's transfer agent.

Accounting services are provided to the Trust by MLAM at cost.

Certain officers and/or trustees of the Trust are officers and/or directors
of MLIM, FDS, MLFD, MLPF&S, and/or Merrill Lynch & Co., Inc.

3. Shares of Beneficial Interest:
The number of shares purchased and redeemed during the years ended 
December 31, 1993 and December 31, 1992, corresponds to the amounts 
included in the Statements of Changes in Net Assets for net proceeds 
from sale of shares and cost of shares redeemed, respectively, since 
shares are recorded at $1.00 per share.

                                    APPENDIX
 
            DESCRIPTION OF COMMERCIAL PAPER, BANK MONEY INSTRUMENTS
                           AND CORPORATE BOND RATINGS
 
COMMERCIAL PAPER AND BANK MONEY INSTRUMENTS
 
     Commercial paper with the greatest capacity for timely payment is rated A
by Standard & Poor's Corporation ("S&P"). Issues within this category are
further redefined with designations 1, 2 and 3 to indicate the relative degree
of safety; A-1, the highest of the three, indicates the degree of safety is
either overwhelming or very strong; A-2 indicates that capacity for timely
repayment is strong.
 
     Moody's Investors Service ("Moody's") employs the designations of Prime-1,
Prime-2 and Prime-3 to indicate the relative capacity of the rated issuers to
repay punctually. Prime-1 issues have a superior capacity for repayment. Prime-2
issues have a strong capacity for repayment, but to a lesser degree than
Prime-1.
 
     Commercial paper rated A.1+ by IBCA Limited or its affiliate IBCA Inc.
(together, "IBCA") are obligations supported by the highest capacity for timely
repayment. Commercial paper rated A.1 has a very strong capacity for timely
repayment. Commercial paper rated A.2 has a strong capacity for timely
repayment, although such capacity may be susceptible to adverse changes in
business, economic or financial conditions.
 
     Fitch Investors Services, Inc. ("Fitch") employs the rating F-1+ to
indicate issues regarded as having the strongest degree of assurance for timely
payment. The rating F-1 reflects an assurance of timely payment only slightly
less in degree than issues rated F-1+, while the rating F-2 indicates a
satisfactory degree of assurance for timely payment, although the margin of
safety is not as great as indicated by the F-1+ and F-1 categories.
 
     Duff & Phelps, Inc. ("Duff & Phelps") employs the designation of Duff 1
with respect to top grade commercial paper and bank money instruments. Duff 1+
indicates the highest certainty of timely payment: short-term liquidity is
clearly outstanding, and safety is just below risk-free U.S. Treasury short-term
obligations. Duff 1- indicates high certainty of timely payment. Duff 2
indicates good certainty of timely payment: liquidity factors and company
fundamentals are sound.
 
     Thompson BankWatch, Inc. ("TBW") employs the designations TBW-1, TBW-2,
TBW-3 and TBW-4 as ratings for commercial paper, other senior short-term
obligations and deposit obligations of the entities to which the rating has been
assigned. TBW-1 is the highest category and indicates a very high degree of
likelihood that principal and interest will be paid on a timely basis. TBW-2 is
the second highest category and indicates that while the degree of safety
regarding timely repayment of principal and interest is strong, the relative
degree of safety is not as high as for issues rated TBW-1.
 
CORPORATE BONDS
 
     Bonds rated AAA have the highest rating assigned by S&P to a debt
obligation. Capacity to pay interest and repay principal is extremely strong.
Bonds rated AA have a very strong capacity to pay interest and repay principal
and differ from the highest rated issues only in a small degree.
 
     Bonds rated Aaa by Moody's are judged to be of the best quality. Interest
payments are protected by a large or by an exceptionally stable margin and
principal is secure. Bonds rated Aa are judged to be of high quality by all
standards. They are rated lower then the best bonds because margins of
protection may not be as large or fluctuation of protective elements may be of
greater amplitude or there may be other elements present which make the
long-term risks appear somewhat larger than in Aaa securities. Moody's applies
numerical
 
                                       35
<PAGE>   62
 
modifiers, 1, 2 and 3 in each generic rating classification from Aa through B in
its corporate bond rating system. The modifier 1 indicates that the security
ranks in the higher end of its generic rating category; the modifier 2 indicates
a mid-range ranking; and the modifier 3 indicates that the issue ranks in the
lower end of its generic rating category.
 
     Bonds rated AAA by IBCA are obligations for which there is the lowest
expectation of investment risk. Capacity for timely repayment of principal and
interest is substantial such that adverse changes in business, economic or
financial conditions are unlikely to increase investment risk significantly.
Bonds rated AA are obligations for which there is a very low expectation of
investment risk. Capacity for timely repayment of principal and interest is
substantial. Adverse changes in business, economic or financial conditions may
increase investment risk, albeit not very significantly.
 
     Bonds rated AAA by Fitch are considered to be investment grade and of the
highest credit quality. The obligor has an exceptionally strong ability to pay
interest and repay principal, which is unlikely to be affected by reasonably
foreseeable events. Bonds rated AA are considered to be investment grade and of
very high credit quality. The obligor's ability to pay interest and repay
principal is very strong, although not quite as strong as bonds rated AAA.
 
     Bonds rated AAA by Duff & Phelps are deemed to be of the highest credit
quality: the risk factors are negligible, being only slightly more than for
risk-free U.S. Treasury debt. AA indicates high credit quality: protection
factors are strong, and risk is modest but may vary slightly from time to time
because of economic conditions.
 
     Bonds rated AAA by TBW are accorded the highest rating category which
indicates that the ability to repay principal and interest on a timely basis is
very high. AA is the second highest rating category and indicates a superior
ability to repay principal and interest on a timely basis with limited
incremental risk versus issues rated in the highest rating category.

ITEM 27.  INDEMNIFICATION.
 
     Reference is made to Article V of Registrant's Declaration of Trust, as
amended, Article VI of Registrant's By-Laws, and Section 9 of the Distribution
Agreement, which have been filed as exhibits to the Registration Statement.
 
     Insofar as the conditional advancing of indemnification monies for actions
based upon the Investment Company Act may be concerned, such payments will be
made only on the following conditions: (i) the advances must be limited to
amounts used, or to be used, for the preparation or presentation of a defense to
the action, including costs connected with the preparation of a settlement; (ii)
advances may be made only upon receipt of a written promise by, or on behalf of,
the recipient to repay that amount of the advance which exceeds the amount which
it is ultimately determined that he is entitled to receive from the Registrant
by reason of indemnification; and (iii)(a) such promise must be secured by a
surety bond, other suitable insurance or an equivalent form of security which
assures that any repayments may be obtained by the Registrant without delay or
litigation, which bond, insurance or other form of security must be provided by
the recipient of the advance, or (b) a majority of a quorum of the Registrant's
disinterested, non-party Trustees, or an independent legal counsel in a written
opinion, shall determine, based upon a review of readily available facts, that
the recipient of the advance ultimately will be found entitled to
indemnification.
 
   
     In Section 9 of the Distribution Agreement relating to the securities being
offered hereby, the Registrant agrees to indemnify the Distributor and each
person, if any, who controls the Distributor within the meaning of the
Securities Act of 1933, against certain types of civil liabilities arising in
connection with the Registration Statement or Prospectus and Statement of
Additional Information.
    
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to Trustees, officers and controlling persons of the
Registrant and the principal underwriter pursuant to the foregoing provisions or
otherwise, the Registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Act and is, therefore, unenforceable. In the event that a claim
for indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a Trustee, officer or controlling
person of the Registrant and the principal underwriter in connection with the
successful defense of any action, suit or proceeding) is asserted by such
Trustee, officer or controlling person or the principal underwriter in
connection with the shares being registered, the Registrant will, unless in the
opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

     As of January 1, 1994 Merrill Lynch Investment Management, Inc. d/b/a
Merrill Lynch Asset Management was reorganized as a limited partnership,
formally known as Merrill Lynch Asset Management, L.P. and continuing to do
business under the name Merrill Lynch Asset Management ("MLAM"). The general
partner of MLAM is Princeton Services, Inc. and the limited partners are Merrill
Lynch Investment Management, Inc. and Merrill Lynch & Co., Inc. Pursuant to Rule
202(a)(1)-1 under the Investment Advisers Act of 1940 and Rule 2a-6 under the
Investment Company Act of 1940 such reorganization did not constitute an
assignment of this investment advisory agreement since it did not involve a
change of control or management of the investment adviser. Pursuant to the
requirements of Section 205 of the Investment Advisers Act of 1940, however,
Merrill Lynch Asset Management hereby supplements this investment advisory
agreement by undertaking to advise you of any change in the membership of the
partnership within a reasonable time after any such change occurs.

Dear Sirs:
    
 
     This opinion is furnished in connection with the registration by Merrill
Lynch Ready Assets Trust, a Massachusetts business trust (the "Trust"), of
6,022,996,604 shares of beneficial interest, par value of $0.10 per share (the
"Shares"), under the Securities Act of 1933 pursuant to a registration statement
on Form N-1A (File No. 2-52711), as amended (the "Registration Statement").
 
     As counsel for the Trust, we are familiar with the proceedings taken by it
in connection with the authorization, issuance and sale of the Shares. In
addition, we have examined and are familiar with the Declaration of Trust of the
Trust, the By-Laws of the Trust and such other documents as we have deemed
relevant to the matters referred to in this opinion.
 
     Based upon the foregoing, we are of the opinion that the Shares, upon
issuance and sale in the manner referred to in the Registration Statement for
consideration not less than the par value thereof, will be legally issued, fully
paid and non-assessable (except as otherwise provided in the Registration
Statement) shares of beneficial interest of the Trust.
 
     We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the use of our name in the prospectus and
statement of additional information constituting parts thereof.
 
   
                                          Very truly yours,
    
 
   
                                          /s/ BROWN & WOOD
                                          ----------------------------------

                         INDEPENDENT AUDITORS' CONSENT
 
Merrill Lynch Ready Assets Trust:
 
   
We consent to the use in Post-Effective Amendment No. 27 to Registration
Statement No. 2-52711 of our report dated February 4, 1994 appearing in the

Statement, and to the reference to us under the caption "Financial Highlights"
