                                    SUMMARY

     The following is a summary of certain information contained elsewhere in
this Proxy Statement and Prospectus (including documents incorporated by
reference) and is qualified in its entirety by reference to the more complete
information contained in this Proxy Statement and Prospectus and in the
Agreement and Plan, attached hereto as Exhibit I.

The Reorganization

     The Boards of Government Mortgage Fund and Mercury Fund unanimously
approved the Reorganization at Meetings held on April 10, 2002.

     Following the Reorganization, the Board of Asset Program will take action
to terminate Mercury Fund as a series of Asset Program under Maryland law.

What will Stockholders of Mercury Fund Receive in the Reorganization?

     If the Agreement and Plan is approved and the Reorganization is
consummated:

     o    You will become a stockholder of Government Mortgage Fund; and

     o    You will receive shares of Government Mortgage Fund with the same
          aggregate net asset value as the shares of Mercury Fund that you
          held immediately prior to the Reorganization as follows:

               If prior to the Reorganization        After the Reorganization
               you held shares of Mercury Fund       you will hold shares of
               of                                    Government Mortgage Fund of
               --------------------------------      ---------------------------

               Class I                               Class A
               Class A                               Class D
               Class B                               Class B
               Class C                               Class C

     The Reorganization has been structured with the intention that it qualify
as a tax-free reorganization for Federal income tax purposes. See "The
Reorganization--Tax Consequences of the Reorganization." You should consult
your tax adviser regarding the tax effects of the Reorganization in light of
your individual circumstances.

What are the Reasons for the Reorganization?

     The Board of Mercury Fund, including all of the Board Members who are not
"interested persons" of Mercury Fund as defined in the Investment Company Act
of 1940, as amended (the "Investment Company Act"), has determined that the
Reorganization is in the best interests of Mercury Fund, and that the
interests of the stockholders of Mercury Fund with respect to net asset value
will not be diluted as a result of effecting the Reorganization. However, a
stockholder of Mercury Fund will hold a lower percentage of ownership in the
Combined Fund than such stockholder holds in Mercury Fund prior to the
Reorganization.

     In reaching its conclusions, the Board of Mercury Fund considered a
number of factors, including the following:

     After the Reorganization, stockholders of Mercury Fund

     o    will remain invested in a diversified open-end fund with a
          substantially larger combined asset base;



                                     -2-


     o    are likely to benefit from reduced operating expenses per share as
          stockholders of the Combined Fund, and are likely to benefit further
          from a reduced management fee rate as stockholders of the Combined
          Fund;

     o    will experience improved economies of scale as stockholders of the
          Combined Fund;

     o    are expected to benefit from greater flexibility in portfolio
          management as stockholders of the Combined Fund; and

     o    may redeem their shares or exchange them into certain other Merrill
          Lynch mutual funds.

     In addition, the Board considered FAM's agreement to bear expenses of the
Reorganization attributable to Mercury Fund in excess of $116,000.

     See "Fee Tables" below and "The Reorganization--Potential Benefits to
Stockholders of Mercury Fund as a Result of the Reorganization."

     If all of the requisite approvals are obtained with respect to the
Reorganization, it is anticipated that the Reorganization will occur as soon
as practicable after such approvals, provided that the Funds have obtained an
opinion of counsel concerning the tax consequences of the Reorganization as
set forth in the Agreement and Plan. Under the Agreement and Plan, the
Reorganization may be abandoned at any time (whether before or after approval
thereof by the stockholders of Mercury Fund) prior to the Closing Date (as
defined below), or the Closing Date may be postponed, (i) by consent of the
Boards of the Funds; (ii) by the Board of Mercury Fund if any condition of
Mercury Fund's obligations has not been fulfilled or waived by such Board; or
(iii) by the Board of Government Mortgage Fund if any condition of Government
Mortgage Fund's obligations has not been fulfilled or waived by such Board.
The Boards of Mercury Fund and Government Mortgage Fund may together amend the
Agreement and Plan to change the terms of the Reorganization at any time prior
to the approval thereof by the stockholders of Mercury Fund.

Fee Tables

     The fee tables below provide information about the fees and expenses
attributable to shares of each class of the Funds, assuming the Reorganization
had taken place on February 28, 2002, and the estimated pro forma annualized
fees and expenses attributable to each class of shares of the Combined Fund.
Future fees and expenses may be greater or less than those indicated below.

(a)  In addition, Merrill Lynch, Pierce, Fenner & Smith Incorporated may
     charge clients a processing fee (currently $5.35) when a client buys or
     sells shares.

(b)  Class B shares of Mercury Fund automatically convert to Class A shares
     about ten years after initial purchase and will no longer be subject to
     distribution fees. Class B shares of Government Mortgage Fund
     automatically convert to Class D shares about ten years after initial
     purchase and will no longer be subject to distribution fees.

(c)  Some investors may qualify for reductions in the sales charge (load).

(d)  A stockholder may pay a deferred sales charge if such stockholder
     purchases $1 million or more and redeems within one year.

(e)  FAM is currently waiving its management fee from Mercury Fund. Government
     Mortgage Fund has agreed to pay, and the Combined Fund will pay, FAM a
     monthly fee at the annual rate of 0.50% of the average daily net assets
     of the Fund for the first $500 million; 0.475% of the average daily net
     assets of the Fund from $500 million to $1.0 billion; 0.45% of the
     average daily net assets of the Fund from $1.0 billion to $1.5 billion;
     0.425% of the average daily net assets of the Fund from $1.5 billion to
     $2.0 billion; 0.40% of the average daily net assets of the Fund from $2.0
     billion to $2.5 billion; 0.375% of the average daily net assets of the
     Fund from $2.5 billion to $3.5 billion; 0.35% of the average daily net
     assets of the Fund from $3.5 billion to $5.0 billion; 0.325% of the
     average daily net assets of the Fund from $5.0 billion to $6.5 billion;
     0.30% of the average daily net assets of the Fund in excess of $6.5
     billion.

(f)  Government Mortgage Fund and Mercury Fund each call the "Service Fee" an
     "Account Maintenance Fee." Account Maintenance Fee is the term used in
     the Prospectuses of the Funds and all other Fund materials. If a
     stockholder holds Class B shares or Class C shares over time, it may cost
     that stockholder more in distribution (12b-1) fees than the maximum sales
     charge that such stockholder would have paid if he or she had bought one
     of the other classes.

(g)  Financial Data Services, Inc. ("FDS"), an affiliate of FAM, provides
     transfer agency services to Government Mortgage Fund and Mercury Fund.
     The Funds each pay a fee for these services. FAM, or its affiliates, also
     provide certain accounting services to these Funds and the Funds
     reimburse FAM, or its affiliates, for such services.

(h)  FAM has agreed to voluntarily waive management fees and/or reimburse
     expenses of Mercury Fund. The Total Annual Fund Operating Expenses for
     Mercury Fund shown in the table do not reflect such voluntary
     management fee waiver and/or reimbursement of expenses because FAM may
     discontinue them at any time without notice. After giving effect to such
     waiver and reimbursement, the Total Annual Fund Operating Expenses for
     Mercury Fund was 0.25% for Class A shares, 0.75% for Class B shares and
     0.80% for Class C shares. All management fees and other expenses for
     Class I shares were waived or reimbursed.

EXAMPLES:

These examples assume that you invest $10,000 in the relevant Fund for the
time periods indicated, that your investment has a 5% return each year, that
you pay the sales charges, if any, that apply to the particular class and that

indicate that you will receive a 5% annual rate of return. Your annual return
may be more or less than the 5% used in these examples. Although your actual
costs may be higher or lower, based on these assumptions your costs would be:

    deferred sales charge ("CDSC") for four years after the purchase of
    shares, while Class B shares of Mercury Fund are subject to a CDSC for
    six years after the purchase of shares. If Class B shares of Mercury Fund
    were subject to the same CDSC schedule as Government Mortgage Fund, an
    investor's expenses for the 1, 3, 5 and 10 year periods assuming

Government Mortgage Fund                    Government Mortgage Fund was organized under the laws of the Commonwealth of
                                            Massachusetts on July 20, 1984. Government Mortgage Fund is a diversified, open-end
                                            investment company.

                                            As of June 28, 2002, Government Mortgage Fund had net assets of approximately $1.9
                                            billion.

Mercury Fund                                Mercury Fund is one of three series of Asset Program, which was incorporated under the
                                            laws of the State of Maryland on May 12, 1994. Asset Program is a diversified, open-end
                                            investment company.

                                            As of June 28, 2002, Mercury Fund had net assets of approximately $81 million.

Comparison of the Funds                     Investment Objectives. The investment objectives of Government  Mortgage Fund and
                                            Mercury Fund are substantially similar. Both Funds seek high current return through a
                                            fully managed investment policy utilizing U.S. Government securities, U.S. Government
                                            agency securities, including Government National Mortgage Association ("GNMA")
                                            mortgage-backed certificates ("GNMA Certificates") and other mortgage-backed government
                                            securities.

                                            Investment Policies. Each of Government Mortgage Fund and Mercury Fund invests in a
                                            portfolio of securities that are issued or guaranteed by the U.S. Government, by various
                                            agencies of the U.S. Government and by various instrumentalities which have been
                                            established or sponsored by the U.S. Government, with the combination varying in
                                            response to changing markets and conditions. In choosing investments, the Funds consider
                                            various factors, including the relative yields of different types of U.S. Government
                                            securities, the Fund's assessment of future interest rate patterns and the desirability
                                            of holding U.S. Government securities on which they may write covered options. Each Fund
                                            may seek to enhance its return through the use of certain portfolio strategies involving
                                            options and to hedge its portfolio through the use of options and futures transactions.
                                            Neither Fund is limited as to the maturities of its portfolio investments. Each Fund may
                                            also invest up to 5% of its assets in obligations issued or guaranteed by the
                                            International Bank for Reconstruction and Development, an international organization of
                                            which the United States is a member country.

                                            Under normal circumstances, at least 80% of Government Mortgage Fund's total assets
                                            consists of GNMA Certificates, other U.S. Government securities representing ownership
                                            interests in mortgage pools, or U.S. Government securities of issuers whose primary
                                            purpose is to facilitate the making of residential or commercial mortgages. Mercury Fund
                                            has authority to invest in all securities issued or guaranteed by the U.S. Government or
                                            its agencies of any maturity, although under certain circumstances a significant portion
                                            of its assets may consist of GNMA Certificates and other U.S. Government securities
                                            representing ownership interests in mortgage pools. Mercury Fund invests substantially
                                            all (at least 80%) of its total assets in



                                                                -8-


                                            securities issued or guaranteed by the U.S. Government, U.S. Government agencies or U.S.
                                            Government sponsored enterprises.

                                            Portfolio Management. FAM serves as the investment adviser to Government Mortgage Fund.
                                            FAM, doing business as Mercury Advisors, serves as the investment adviser to Mercury
                                            Fund. FAM is responsible for the management of the investment portfolio and for
                                            providing administrative services to each Fund.

                                            The portfolio managers of Government Mortgage Fund and Mercury Fund are Frank Viola and
                                            Teresa L. Giacino, who have served as portfolio managers of the Funds since 2001. Mr.
                                            Viola and Ms. Giacino will serve as portfolio managers of the Combined Fund.

                                            Management Fees. Pursuant to a management agreement with FAM, Government Mortgage Fund
                                            pays FAM a monthly management fee at the annual rate calculated as follows:

                                                      Portion of average daily value           Management Fee
                                                              of net assets:

                                            Pursuant to a management agreement between FAM and Mercury Fund, Mercury Fund pays FAM a
                                            monthly fee at the annual rate of 0.50% of the Fund's average daily net assets. FAM has
                                            voluntarily waived management fees and/or reimbursed expenses of the Mercury Fund since
                                            commencement of the Fund's operations. However, such waiver and/or reimbursement may be
                                            discontinued by FAM at any time without notice.

                                            After the Reorganization, the effective management fee rate applicable to the Combined
                                            Fund, at current asset levels, would be lower than Mercury Fund's current management fee
                                            rate.

                                            See "Summary--Fee Tables" and "Comparison of the Funds--Management."

                                            Class Structure. Government Mortgage Fund and Mercury Fund each offer four classes of
                                            common stock. Government Mortgage Fund's Class A, Class D, Class B and Class C shares
                                            are substantially the same as Mercury Fund's Class I, Class A, Class B and Class C
                                            shares, respectively, except that (i) they represent ownership interests in a different
                                            investment portfolio; and (ii) Class B shares of Government Mortgage Fund are subject to
                                            a different contingent deferred sales charge ("CDSC") schedule and for a period of four
                                            years rather than the six years associated with the corresponding Class B shares of
                                            Mercury Fund. See "Comparison of the Funds--Purchase of Shares,"

                                           ***  FAM has voluntarily waived management fees and/or  reimbursed expenses of
                                                Mercury Fund. The Total Annual Fund Operating Expenses shown in the table do not
                                                reflect such voluntary management fee waiver and/or reimbursement of expenses

                                            Purchase of Shares. Shares of Government Mortgage Fund are offered continuously for sale
                                            to the public in the same manner as shares of Mercury Fund. See "Comparison of the
                                            Funds--Purchase of Shares."

                                            Redemption of Shares. The redemption procedures for shares of Government Mortgage Fund
                                            are the same as the redemption procedures for shares of Mercury Fund. For purposes of
                                            computing any CDSC that may be payable upon disposition of shares of Government Mortgage
                                            Fund distributed to Mercury Fund stockholders in the Reorganization, the holding period
                                            of Mercury Fund shares outstanding on the date the Reorganization takes place will be
                                            "tacked" onto the holding period of the shares of Government Mortgage Fund distributed
                                            in the Reorganization. See "Comparison of the Funds--Redemption of Shares."

                                            Dividends. Each Fund distributes its net investment income monthly and net realized
                                            capital gains, if any, at least annually. See "Comparison of the Funds--Dividends and

                                            Net Asset Value. Mercury Fund and Government Mortgage Fund each determines net asset
                                            value of each class of shares once daily, Monday through Friday, as of the close of
                                            business on the New York Stock Exchange ("NYSE"), generally 4:00 p.m. New York time, on
                                            each day the NYSE is open for trading (a "Business Day") based on prices at the time of
                                            closing. The Funds compute net asset value per share in the same manner. See "Comparison
                                            of the Funds--Additional Information--Net Asset Value."

                                            Voting Rights. The corresponding voting rights of the stockholders of the Funds are
                                            substantially similar. See "Comparison of the Funds--Additional Information--Capital
                                            Stock."

                                            Other Significant Considerations. Stockholder services, including exchange privileges,
                                            available to Mercury Fund and Government Mortgage Fund stockholders are similar. See
                                            "Comparison of the Funds--Additional Information--Stockholder Services." An automatic
                                            dividend reinvestment plan is available to stockholders of each Fund. The plans are
                                            similar. See "Comparison of the Funds--Automatic Dividend Reinvestment Plan." Other
                                            stockholder services, including the provision of annual and semi-annual reports, are the
                                            same for both Funds. "Comparison of the Funds--Stockholder Services."

Tax Considerations                          The Funds will receive an opinion of counsel with respect to the Reorganization  to the
                                            effect that, among other things, neither Government Mortgage Fund nor Mercury Fund will
                                            recognize any gain or loss on the transaction, and no stockholder of Mercury Fund will
                                            recognize any gain or loss upon receipt of shares of Government Mortgage Fund.
                                            Consummation of the Reorganization is subject to the receipt of such opinion of counsel.
                                            See "The Reorganization--Tax Consequences of the Reorganization." The Reorganization
                                            will not affect the status of Government Mortgage Fund as a regulated investment
                                            company.

                    RISK FACTORS AND SPECIAL CONSIDERATIONS

     The investment risks associated with an investment in Mercury Fund are
substantially similar to the principal investment risks associated with an
investment in Government Mortgage Fund. Such risks include interest rate risk,
credit risk, market and selection risk, mortgage backed securities risk,
borrowing risk, call and redemption risk, securities lending risk, derivatives
risk, indexed and inverse floating rate securities risk, repurchase agreements
risk, as well as the risks associated with investing in when issued
securities, delayed delivery securities, forward commitments, illiquid
securities, restricted securities, Rule 144A securities and swap agreements.
The risk factors associated with an investment in Government Mortgage Fund are
set forth below and in the Government Mortgage Fund Prospectus that
accompanies this Proxy Statement and Prospectus under the caption "Details
about the Fund--Investment Risks."

     Unless otherwise noted, each Fund is subject to the following principal
risks.

Interest Rate Risk -- Interest rate risk is the risk that prices of bonds
generally increase when interest rates decline and decrease when interest
rates increase. Prices of longer term securities generally change more in
response to interest rate changes than prices of shorter term securities.

Credit Risk -- Credit risk is the risk that the issuer will be unable to pay
the interest or principal when due. The degree of credit risk depends on both
the financial condition of the issuer and the terms of the obligation.

Market and Selection Risk -- Market risk is the risk that the bond market will
go down in value, including the possibility that the market will go down
sharply and unpredictably. Selection risk is the risk that the securities that
Fund management selects will underperform the bond market, relevant indices or
other funds with similar investment objectives and investment strategies.

Mortgage Backed Securities -- Mortgage backed securities represent the right
to receive a portion of principal and/or interest payments made on a pool of
residential or commercial mortgage loans. When interest rates fall, borrowers
may refinance or otherwise repay principal on their mortgages earlier than
scheduled. When this happens, certain types of mortgage backed securities will
be paid off more quickly than originally anticipated and a Fund has to invest
the proceeds in securities with lower yields. This risk is known as
"prepayment risk." When interest rates rise, certain types of mortgage backed
securities will be paid off more slowly than originally anticipated and the
value of these securities will fall. This risk is known as "extension risk."
Because of prepayment risk and extension risk mortgage backed securities react
differently to changes in interest rates than other fixed income securities.
Small movements in interest rates (both increase and decrease) may quickly and
significantly reduce the value of certain mortgage backed securities.

Most mortgage backed securities are issued by Federal government agencies,
such as the Government National Mortgage Association ("GNMA"), the Federal
Home Loan Mortgage Corporation ("Freddie Mac"), or the Federal National
Mortgage Association ("Fannie Mae"). Principal and interest payments on
mortgage backed securities issued by Federal government agencies are
guaranteed by either the Federal government or the government agency. Such
securities have very little credit risk, but may be subject to substantial
interest rate risks.

Mortgage backed securities may be either pass-through securities or
collateralized mortgage obligations (CMOs). Pass-through securities represent
a right to receive principal and interest payments collected on a pool of
mortgages, which are passed through to security holders (less servicing
costs). CMOs are created by dividing the principal and interest payments
collected on a pool of mortgages into several revenue streams (tranches) with
different priority rights to portions of the underlying mortgage payments.
Certain CMO tranches may represent a right to receive interest only (IOs),
principal only (POs) or an amount that remains after other floating-rate
tranches are paid (an inverse floater). These securities are frequently
referred to as "mortgage derivatives" and may be extremely sensitive to
changes in interest rates. If a Fund invests in CMO tranches issued by
government agencies and interest rates move in a manner not anticipated by
Fund management, it is possible that the Fund could lose all or substantially
all of its investment.



                                     -12-


Borrowing Risk -- Each Fund may borrow for temporary or emergency purposes
including to meet redemptions. Borrowing may exaggerate changes in the net
asset value of Fund shares and in the yield on the Fund's portfolio. Borrowing
will cost the Fund interest expense and other fees. The cost of borrowing may
reduce the Fund's return.

Call and Redemption Risk -- A bond's issuer may call a bond for redemption
before it matures. If this happens to a bond a Fund holds, the Fund may lose
income and may have to invest the proceeds in bonds with lower yields.

Securities Lending -- Each Fund may lend securities with a value not exceeding
33 1/3% of its total assets to financial institutions that provide cash or
securities issued or guaranteed by the U.S. as collateral. Securities lending
involves the risk that the borrower may fail to return the securities in a
timely manner or at all. As a result, the Fund may lose money and there may be
a delay in recovering the loaned securities. The Fund could also lose money if
it does not recover the securities and/or the value of the collateral falls,
including the value of investments made with cash collateral. These events
could trigger adverse tax consequences to the Fund.

Derivatives -- Each Fund may use derivative instruments including indexed and
inverse securities, futures, options, options on futures, interest rate swaps
and credit default swaps. Derivatives allow the Fund to increase or decrease
its risk exposure more quickly and efficiently than other types of
instruments.

Derivatives are volatile and involve significant risks, including:

         o Credit risk -- the risk that the counterparty (the party on the
           other side of the transaction) on a derivative transaction will be
           unable to honor its financial obligation to the Fund.

         o Leverage risk -- the risk associated with certain types of
           investments or trading strategies that relatively small market
           movements may result in large changes in the value of an
           investment. Certain investments or trading strategies that involve
           leverage can result in losses that greatly exceed the amount
           originally invested.

         o Liquidity risk -- the risk that certain securities may be difficult
           or impossible to sell at the time that the seller would like or at
           the price that the seller believes the security is currently worth.

Each Fund may use derivatives for hedging purposes, including anticipatory
hedges, as well as to seek to enhance total returns. Hedging is a strategy in
which the Fund uses a derivative to offset the risks associated with other
Fund holdings. While hedging can reduce losses, it can also reduce or
eliminate gains or cause losses if the market moves in a different manner than
anticipated by the Fund or if the cost of the derivative outweighs the benefit
of the hedge. Hedging also involves the risk that changes in the value of the
derivative will not match those of the holdings being hedged as expected by
the Fund, in which case any losses on the holdings being hedged may not be
reduced. There can be no assurance that the Fund's hedging strategy will
reduce risk or that hedging transactions will be either available or cost
effective. The Funds are not required to use hedging and may choose not to do
so.

Indexed and Inverse Floating Rate Securities -- Each Fund may invest in
securities whose potential returns are directly related to changes in an
underlying index or interest rate, known as indexed securities. The return on
indexed securities will rise when the underlying index or interest rate rises
and fall when the index or interest rate falls. The Funds may also invest in
securities whose return is inversely related to changes in an interest rate
(inverse floaters). In general, income on inverse floaters will decrease when
interest rates increase and increase when interest rates decrease. Investments
in inverse floaters may subject the Fund to the risks of reduced or eliminated
interest payments and losses of principal. In addition, certain indexed
securities and inverse floaters may increase or decrease in value at a greater
rate than the underlying interest rate, which effectively leverages the Fund's
investment. Indexed securities and inverse floaters are derivative securities
and can be considered speculative. Indexed and inverse securities involve
credit risk and certain indexed and inverse securities may involve currency
risk, leverage risk and liquidity risk.

Repurchase Agreements -- Each Fund may enter into certain types of repurchase
agreements. Under a repurchase agreement, the seller agrees to repurchase a
security at a mutually agreed upon time and price. If the other party to a



                                     -13-


repurchase agreement defaults on its obligation, the Fund may suffer delays
and incur costs or even lose money in exercising its rights under the
agreement.

When Issued Securities, Delayed Delivery Securities and Forward Commitments --
When issued and delayed delivery securities and forward commitments involve
the risk that the security a Fund buys will lose value prior to its delivery.
There also is the risk that the security will not be issued or that the other
party will not meet its obligation. If this occurs, the Fund both loses the
investment opportunity for the assets it has set aside to pay for the security
and any gain in the security's price.

Illiquid Securities -- Each Fund may invest up to 15% of its net assets in
illiquid securities that it cannot easily sell within seven days at current
value or that have contractual or legal restrictions on resale. If a Fund buys
illiquid securities it may be unable to quickly sell them or may be able to
sell them only at a price below current value.

Restricted Securities -- Restricted securities have contractual or legal
restrictions on their resale. They may include private placement securities
that a Fund buys directly from the issuer. Private placement and other
restricted securities may not be listed on an exchange and may have no active
trading market.

Restricted securities may be illiquid. The Funds may be unable to sell them on
short notice or may be able to sell them only at a price below current value.
The Funds may get only limited information about the issuer, so it may be less
able to predict a loss. In addition, if a Fund's management receives material
adverse nonpublic information about the issuer, the Fund will not be able to
sell the securities.

Rule 144A Securities -- Rule 144A securities are restricted securities that
can be resold to qualified institutional buyers, but not to the general
public. Rule 144A securities may have an active trading market, but carry the
risk that the active trading market may not continue.

Swap Agreements -- Swap agreements involve the risk that the party with whom
the Fund has entered into the swap will default on its obligation to pay the
Fund and the risk that the Fund will not be able to meet its obligations to
pay the other party to the agreement. Mercury Fund does not invest in swap
agreements.

Investment Objectives and Policies

     The investment objectives of Government Mortgage Fund and Mercury Fund
are substantially similar. Each Fund seeks high current return through
investments primarily in U.S. Government and government agency securities,
including GNMA Certificates and other mortgage backed government securities.

     Government Mortgage Fund and Mercury Fund seek to achieve their
investment objectives through fully-managed investment policies utilizing U.S.
Government and government agency securities, including GNMA Certificates and
other mortgage backed government securities. Under normal circumstances, at
least 80% of Government Mortgage Fund's total assets consists of GNMA
Certificates, other U.S. Government securities representing ownership
interests in mortgage pools, or U.S. Government securities of issuers whose
primary purpose is to facilitate the making of residential or commercial
mortgages. Mercury Fund has authority to invest in all securities issued or
guaranteed by the U.S. Government or its agencies of any maturity, although
under certain circumstances a significant portion of its assets may consist of
GNMA Certificates and other U.S. Government securities representing ownership
interests in mortgage pools. Mercury Fund invests substantially all (at least
80%) of its total assets in securities issued or guaranteed by the U.S.
Government, U.S. Government agencies or U.S. Government sponsored enterprises.
In choosing investments, Government Mortgage Fund and Mercury Fund each
considers factors such as the relative yields of different types of U.S.
Government securities and its assessment of future interest rate patterns.
Neither Government Mortgage Fund nor Mercury Fund is limited as to the
maturities of their portfolio investments. The Funds may seek to enhance their
return through the use of options and futures transactions. The hedging
strategies are intended to reduce volatility in the net asset value of Fund
shares.

     The investment objective of each Fund is a fundamental policy of the Fund
and may not be changed without the approval of a majority of the Fund's
outstanding voting securities as defined in the Investment Company Act.

     Government Mortgage Fund and Mercury Fund have the following investment
strategies and policies.

     GNMA Certificates and Other Mortgage Backed Government Securities. Each
Fund invests in GNMA Certificates. GNMA Certificates are mortgage backed
securities of the modified pass through type, which means that both interest
and principal payments (including prepayments) are passed through monthly to
the holder of the Certificate. The National Housing Act provides that the full
faith and credit of the United States is pledged to the timely payment of
principal and interest by GNMA of amounts due on these GNMA Certificates. Each
Certificate evidences an interest in a specific pool of mortgage loans insured
by the Federal Housing Administration ("FHA") or the Farmers Home
Administration or guaranteed by the Veterans Administration ("VA"). GNMA is a
wholly owned corporate instrumentality of the United States within the
Department of Housing and Urban Development.

     The average life of GNMA Certificates varies with the maturities of the
underlying mortgage instruments, which have maximum maturities of 30 years.
The average life may be substantially less than the original maturity of the
mortgage pools underlying the securities as a result of prepayments or
refinancing of such mortgages. Such prepayments are passed through to the
registered holder with the regular monthly payments of principal and interest.
In addition, GNMA offers a pass through security backed by adjustable rate
mortgages. As prepayment rates vary widely, it is not possible to predict
accurately the average life of a particular pool. The actual yield of each
GNMA Certificate is influenced by the prepayment experience of the mortgage
pool underlying the certificate.

     In addition to GNMA Certificates, Mercury Fund and Government Mortgage
Fund may invest in mortgage backed securities issued by Fannie Mae and by the
Federal Home Loan Mortgage Corporation ("FHLMC"). Fannie Mae, a federally
chartered and privately owned corporation, issues pass through securities and
certificates representing an interest in a pool of Fannie Mae pass through
securities which are guaranteed as to payment of principal and interest by
Fannie Mae. FHLMC, a corporate instrumentality of the United States, issues
participation certificates which represent an interest in mortgages from
FHLMC's portfolio and securities representing an interest in a pool of FHLMC
participation certificates. FHLMC guarantees the timely payment of interest
and the ultimate collection of principal. As is the case with GNMA
Certificates, the actual maturity of and realized yield on particular Fannie
Mae and FHLMC mortgage backed securities will vary based on the prepayment
experience of the underlying pool of mortgages. Securities guaranteed by
Fannie Mae and FHLMC are not backed by the full faith and credit of the United
States.



                                     -19-


     Mortgage backed U.S. Government securities typically provide a higher
potential for current income than other types of U.S. Government securities;
however, U.S. Treasury bills, notes and bonds typically provide a higher
potential for capital appreciation than mortgage backed securities.

     Payments of principal and interest on mortgage backed securities are made
more frequently than are payments on conventional debt securities. In
addition, holders of mortgage backed securities may receive unscheduled
payments of principal at any time representing prepayments on the underlying
mortgage loans or financial assets. Such prepayments may usually be made by
the related obligor without penalty. Prepayment rates are affected by changes
in prevailing interest rates and numerous other economic, geographic, social
and other factors. Changes in the rate of prepayments will generally affect
the yield to maturity of the security. Moreover, when the holder of the
security attempts to reinvest prepayments or even the scheduled payments of
principal and interest, it may receive a rate of interest which is higher or
lower than the rate on the mortgage backed securities originally held. To the
extent that mortgage backed securities are purchased at a premium, mortgage
foreclosures and principal prepayments may result in a loss to the extent of
the premium paid. If such securities are bought at a discount, both scheduled
payments of principal and unscheduled prepayments will increase current and
total returns and will accelerate the recognition of income which, when
distributed to stockholders, will be taxable as ordinary income.

     Derivatives. Mercury Fund and Government Mortgage Fund may use
instruments referred to as Derivatives. Derivatives are financial instruments
the value of which is derived from another security, a commodity (such as gold
or oil) or an index (a measure of value or rates, such as the Standard &
Poor's 500 Index or the prime lending rate). Derivatives allow the Funds to
increase or decrease the level of risk to which the Funds are exposed more
quickly and efficiently than transactions in other types of instruments. The
Funds may use Derivatives for hedging purposes or to seek to increase total
returns.

     Hedging. Hedging is a strategy in which a Derivative is used to offset
the risks associated with Fund holdings. Losses on the other investment may be
substantially reduced by gains on a Derivative that reacts in an opposite
manner to market movements. While hedging can reduce losses, it can also
reduce or eliminate gains or cause losses if the market moves in a different
manner than anticipated by the Fund or if the cost of the Derivative outweighs
the benefit of the hedge. Hedging also involves the risk that changes in the
value of the Derivative will not match those of the holdings being hedged as
expected by the Fund, in which case any losses on the holdings being hedged
may not be reduced.

     The types of Derivative instruments and trading strategies that Mercury
Fund and Government Mortgage Fund may use include the following:

     Options and Futures Portfolio Strategies. Each of Mercury Fund and
Government Mortgage Fund may seek to increase its return through the use of
options on the underlying securities and may hedge all or a portion of its
portfolio investments against fluctuations in interest rates through the use
of options, interest rate futures and options on interest rate futures. While
the Fund's use of hedging strategies is intended to reduce the volatility of
the net asset value of Fund shares, the Fund's net asset value will fluctuate.
The Funds may only engage in hedging activities from time to time and may not
necessarily be engaging in hedging activities when movements in interest rates
occur. There can be no assurance that a Fund's hedging transactions will be
effective.

     Each of Mercury Fund and Government Mortgage Fund is authorized to use
certain strategies involving options and futures. Such instruments are
referred to collectively herein as "Strategic Instruments."

     Options on Securities and Securities Indices. Each of Mercury Fund and
Government Mortgage Fund may invest in options on individual securities and
baskets of securities. Government Mortgage Fund may also invest in options on
particular measurements of value or rate (an "index"), such as an index of the
price of Treasury securities or an index representative of short term interest
rates.

     Purchasing Options. Each of Mercury Fund and Government Mortgage Fund is
authorized to purchase put options on securities held in its portfolio or
securities indices the performance of which is substantially correlated to
securities held in its portfolio. When a Fund purchases a put option, in
consideration for an upfront payment (the "option premium") the Fund acquires
a right to sell to another party specified securities owned by the Fund at a



                                     -20-


specified price (the "exercise price") on or before a specified date (the
"expiration date"), in the case of an option on securities, or to receive from
another party a payment based on the amount a specified securities index
declines below a specified level on or before the expiration date, in the case
of an option on a securities index. The purchase of a put option limits the
Fund's risk of loss in the event of a decline in the market value of the
portfolio holdings underlying the put option prior to the option's expiration
date. If the market value of the portfolio holdings associated with the put
option increases rather than decreases, however, the Fund will lose the option
premium and will consequently realize a lower return on the portfolio holdings
than would have been realized without the purchase of the put.

     Each of Mercury Fund and Government Mortgage Fund is also authorized to
purchase call options on securities it intends to purchase or securities
indices the performance of which substantially correlates with the performance
of the types of securities it intends to purchase. When a Fund purchases a
call option, in consideration for the option premium the Fund acquires a right
to purchase from another party specified securities at the exercise price on
or before the expiration date, in the case of an option on securities, or to
receive from another party a payment based on the amount a specified
securities index increases beyond a specified level on or before the
expiration date, in the case of an option on a securities index. The purchase
of a call option may protect the Fund from having to pay more for a security
as a consequence of increases in the market value for the security during a
period when the Fund is contemplating its purchase, in the case of an option
on a security, or attempting to identify specific securities in which to
invest in a market the Fund believes to be attractive, in the case of an
option on an index (an "anticipatory hedge"). In the event the Fund determines
not to purchase a security underlying a call option, however, the Fund may
lose the entire option premium.

     Each of Mercury Fund and Government Mortgage Fund is also authorized to
purchase put or call options in connection with closing out put or call
options it has previously sold.

     Writing Options. Each of Mercury Fund and Government Mortgage Fund is
authorized to write (i.e., sell) call options on securities held in its
portfolio or securities indices the performance of which is substantially
correlated with securities held in its portfolio. When a Fund writes a call
option, in return for an option premium the Fund gives another party the right
to buy specified securities owned by the Fund at the exercise price on or
before the expiration date, in the case of an option on securities, or agrees
to pay to another party an amount based on any gain in a specified securities
index beyond a specified level on or before the expiration date, in the case
of an option on a securities index. The Fund may write call options to earn
income, through the receipt of option premiums. In the event the party to
which the Fund has written an option fails to exercise its rights under the
option because the value of the underlying securities is less than the
exercise price, the Fund will partially offset any decline in the value of the
underlying securities through the receipt of the option premium. By writing a
call option, however, the Fund limits its ability to sell the underlying
securities, and gives up the opportunity to profit from any increase in the
value of the underlying securities beyond the exercise price, while the option
remains outstanding.

     Each of Mercury Fund and Government Mortgage Fund may also write put
options on securities. Additionally, Government Mortgage Fund may write put
options on securities indices. When a Fund writes a put option, in return for
an option premium the Fund gives another party the right to sell to the Fund a
specified security at the exercise price on or before the expiration date, in
the case of an option on a security, or agrees to pay to another party an
amount based on any decline in a specified securities index below a specified
level on or before the expiration date, in the case of an option on a
securities index. Each Fund may write put options to earn income, through the
receipt of option premiums. In the event the party to which a Fund has written
an option fails to exercise its rights under the option because the value of
the underlying securities is greater than the exercise price, the Fund will
profit by the amount of the option premium. By writing a put option, however,
a Fund will be obligated to purchase the underlying security at a price that
may be higher than the market value of the security at the time of exercise as
long as the put option is outstanding, in the case of an option on a security,
or make a cash payment reflecting any decline in the index, in the case of an
option on an index. Accordingly, when either Fund writes a put option it is
exposed to a risk of loss in the event the value of the underlying securities
falls below the exercise price, which loss potentially may substantially
exceed the amount of option premium received by the Fund for writing the put
option. Each Fund will write a put option on a security (and, in the case of
Government Mortgage Fund, a securities index), only if the Fund would be
willing to purchase the security at the exercise price for investment purposes
(in the case of an option on a security) or is writing the put in connection
with trading strategies involving



                                     -21-


combinations of options -- for example, the sale and purchase of options with
identical expiration dates on the same security or index but different
exercise prices (a technique called a "spread").

     Each of Mercury Fund and Government Mortgage Fund is also authorized to
sell call or put options in connection with closing out call or put options it
has previously purchased.

     Other than with respect to closing transactions, Mercury Fund and
Government Mortgage Fund will only write call or put options that are
"covered." A put option will be considered covered if the Fund has segregated
assets with respect to such option in the manner described in "Risk Factors in
Options and Futures" below. A call option will be considered covered if the
Fund owns the securities it would be required to deliver upon exercise of the
option (or, in the case of an option on a securities index, securities which
substantially replicate the performance of such index) or owns a call option,
warrant or convertible instrument which is immediately exercisable for, or
convertible into, such security.

     Options on GNMA Certificates. The following information relates to unique
characteristics of options on GNMA Certificates. Since the remaining principal
balance of GNMA Certificates declines each month as a result of mortgage
payments, each of Mercury Fund and Government Mortgage Fund, as a writer of a
GNMA call holding GNMA Certificates as "cover" to satisfy its delivery
obligation in the event of exercise, may find that the GNMA Certificates it
holds no longer have a sufficient remaining principal balance for this
purpose. Should this occur, the Fund will purchase additional GNMA
Certificates from the same pool (if obtainable) or other GNMA Certificates in
the cash market in order to maintain its "cover."

     A GNMA Certificate held by Mercury Fund or Government Mortgage Fund to
cover an option position in any but the nearest expiration month may cease to
represent cover for the option in the event of a decline in the GNMA coupon
rate at which new pools are originated under the FHA/VA loan ceiling in effect
at any given time. If this should occur, the Fund will no longer be covered,
and the Fund will either enter into a closing purchase transaction or replace
such Certificate with a certificate which represents cover. When the Fund
closes its position or replaces such Certificate, it may realize an
unanticipated loss and incur transaction costs.

     Types of Options. Each of Mercury Fund and Government Mortgage Fund may
engage in transactions in options on securities or securities indices on
exchanges and in the over the counter ("OTC") markets. In general, exchange
traded options have standardized exercise prices and expiration dates and
require the parties to post margin against their obligations, and the
performance of the parties' obligations in connection with such options is
guaranteed by the exchange or a related clearing corporation. OTC options have
more flexible terms negotiated between the buyer and the seller, but generally
do not require the parties to post margin and are subject to greater risk of
counterparty default. See "Additional Risk Factors of OTC Transactions;
Limitations on the Use of OTC Strategic Instruments" below.

     Futures. Each of Mercury Fund and Government Mortgage Fund may engage in
transactions in futures and options thereon. Futures are standardized,
exchange traded contracts which obligate a purchaser to take delivery, and a
seller to make delivery, of a specific amount of a commodity at a specified
future date at a specified price. No price is paid upon entering into a
futures contract. Rather, upon purchasing or selling a futures contract the
Fund is required to deposit collateral ("margin") equal to a percentage
(generally less than 10%) of the contract value. Each day thereafter until the
futures position is closed, the Fund will pay additional margin representing
any loss experienced as a result of the futures position the prior day or be
entitled to a payment representing any profit experienced as a result of the
futures position the prior day.

     The sale of a futures contract limits each Fund's risk of loss through a
decline in the market value of portfolio holdings correlated with the futures
contract prior to the futures contract's expiration date. In the event the
market value of the portfolio holdings correlated with the futures contract
increases rather than decreases, however, each Fund will realize a loss on the
futures position and a lower return on the portfolio holdings than would have
been realized without the purchase of the futures contract.

     The purchase of a futures contract may protect each Fund from having to
pay more for securities as a consequence of increases in the market value for
such securities during a period when the Fund was attempting to identify
specific securities in which to invest in a market the Fund believes to be
attractive. In the event that such



                                     -22-


securities decline in value or such Fund determines not to complete an
anticipatory hedge transaction relating to a futures contract, however, the
Fund may realize a loss relating to the futures position.

     In order to comply with current applicable regulations of the Commodity
Futures Trading Commission ("CFTC") pursuant to which the Funds avoid being
deemed a "commodity pool operator," the Funds are limited in their futures
trading activities to positions which constitute "bona fide hedging" positions
within the meaning and intent of applicable CFTC rules, or to non-hedging
positions for which the aggregate initial margin and premiums will not exceed
5% of the liquidation value of either Fund's assets.

     Risk Factors in Options and Futures. Use of Strategic Instruments for
hedging purposes involves the risk of imperfect correlation in movements in
the value of the Strategic Instruments and the value of the instruments being
hedged. If the value of the Strategic Instruments moves more or less than the
value of the hedged instruments Mercury Fund or Government Mortgage Fund will
experience a gain or loss which will not be completely offset by movements in
the value of the hedged instruments.

     Each of Mercury Fund and Government Mortgage Fund intends to enter into
transactions involving Strategic Instruments only if there appears to be a
liquid secondary market for such instruments or, in the case of illiquid
instruments traded in OTC transactions, such instruments satisfy the criteria
set forth below under "Additional Risk Factors of OTC Transactions;
Limitations on the Use of OTC Strategic Instruments." However, there can be no
assurance that, at any specific time, either a liquid secondary market will
exist for a Strategic Instrument or either Fund will otherwise be able to sell
such instrument at an acceptable price. It may therefore not be possible to
close a position in a Strategic Instrument without incurring substantial
losses, if at all.

     Certain transactions in Strategic Instruments (e.g., futures
transactions, sales of put options) and other types of transactions in which
each Fund may engage (e.g., delayed delivery transactions, discussed below)
may expose each Fund to potential losses which exceed the amount originally
invested by such Fund in such instruments. When Mercury Fund or Government
Mortgage Fund engages in such a transaction, the Fund will deposit in a
segregated account at its custodian liquid securities with a value at least
equal to the Fund's exposure, on a mark-to-market basis, to the transaction
(as calculated pursuant to requirements of the Commission). Such segregation
will ensure that the Fund has assets available to satisfy its obligations with
respect to the transaction, but will not limit the Fund's exposure to loss.

     Additional Risk Factors of OTC Transactions; Limitations on the Use of
OTC Strategic Instruments. Certain Strategic Instruments traded in OTC
markets, including OTC options, may be substantially less liquid than other
instruments in which Mercury Fund or Government Mortgage Fund may invest. The
absence of liquidity may make it difficult or impossible for each Fund to sell
such instruments promptly at an acceptable price. The absence of liquidity may
also make it more difficult for the Fund to ascertain a market value for such
instruments. Each Fund will therefore acquire illiquid OTC instruments (i) if
the agreement pursuant to which the instrument is purchased contains a formula
price at which the instrument may be terminated or sold, or (ii) for which
Fund management anticipates the Fund can receive on each business day at least
two independent bids or offers, unless a quotation from only one dealer is
available, in which case that dealer's quotation may be used.

     The staff of the Commission has taken the position that purchased OTC
options and the assets underlying written OTC options are illiquid securities.
Each of Mercury Fund and Government Mortgage Fund has therefore adopted an
investment policy pursuant to which it will not purchase or sell OTC options
(including OTC options on futures contracts) if, as a result of such
transactions, the sum of the market value of OTC options currently outstanding
which are held by the Fund, the market value of the securities underlying OTC
call options currently outstanding which have been sold by the Fund and margin
deposits on the Fund's outstanding OTC options exceeds 15% of the net assets
of the Fund, taken at market value, together with all other assets of the Fund
which are deemed to be illiquid or are otherwise not readily marketable.
However, if an OTC option is sold by either Fund to a dealer in U.S.
Government securities recognized as a "primary dealer" by the Federal Reserve
Bank of New York and the Fund has the unconditional contractual right to
repurchase such OTC option at a predetermined price, then the Fund will treat
as illiquid such amount of the underlying securities as is equal to the
repurchase price less the amount by which the option is "in-the-money" (i.e.,
current market value of the underlying security minus the option's exercise
price).



                                     -23-


     Because Strategic Instruments traded in OTC markets are not guaranteed by
an exchange or clearing corporation and generally do not require payment of
margin, to the extent that Government Mortgage Fund or Mercury Fund have
unrealized gains in such instruments or has deposited collateral with its
counterparty such Fund is at risk that its counterparty will become bankrupt
or otherwise fail to honor its obligations. Government Mortgage Fund and
Mercury Fund will attempt to minimize the risk that a counterparty will become
bankrupt or otherwise fail to honor its obligations by engaging in
transactions in Strategic Instruments traded in OTC markets only with
financial institutions which have substantial capital or which have provided
the Fund with a third party guaranty or other credit enhancement.

     Additional Limitations on the Use of Strategic Instruments. Neither
Government Mortgage Fund nor Mercury Fund may use any Strategic Instrument to
gain exposure to an asset or type or class of assets that it would be
prohibited by its investment restrictions from purchasing directly.

     Interest Rate Swaps, Caps and Floors. Government Mortgage Fund and
Mercury Fund may enter into interest rate swaps, which are OTC contracts in
which each party agrees to make a periodic payment based on an index or the
value of an asset in return for a periodic payment from the other party based
on a different index or asset.

     In order to hedge the value of a Fund's portfolio against interest rate
fluctuations or to enhance a Fund's income, a Fund may enter into various
transactions, such as interest rate swaps and the purchase or sale of interest
rate caps and floors. The Funds expect to enter into these transactions
primarily to preserve a return or spread on a particular investment or portion
of its portfolio or to protect against any increase in the price of securities
the Funds anticipate purchasing at a later date. The Funds intend to use these
transactions primarily as a hedge and not as a speculative investment.
However, the Funds may also invest in interest rate swaps to enhance income or
to increase their yield during periods of steep interest rate yield curves
(i.e., wide differences between short term and long term interest rates).

     The Funds usually will enter into interest rate swap transactions on a
net basis, i.e., the two payment streams are netted out, with the Funds
receiving or paying, as the case may be, only the net amount of the two
payments. Inasmuch as these transactions are entered into for good faith
hedging purposes, FAM believes that such obligations do not constitute senior
securities and, accordingly, will not treat them as being subject to its
borrowing restrictions. The net amount of the excess, if any, of such Fund's
obligations over its entitlements with respect to each interest rate swap will
be accrued on a daily basis, and an amount of cash or liquid securities having
an aggregate net asset value at least equal to the accrued excess will be
maintained in a segregated account by the Fund's custodian. If the interest
rate swap transaction is entered into on other than a net basis, the full
amount of the Fund's obligations will be accrued on a daily basis, and the
full amount of the Fund's obligations will be maintained in a segregated
account by the Fund's custodian.

     In an interest rate swap, the Funds exchange with another party their
respective commitments to pay or receive interest, e.g., an exchange of fixed
rate payments for floating rate payments. For example, if either Fund holds a
mortgage backed security with an interest rate that is reset only once each
year, it may swap the right to receive interest at this fixed rate for the
right to receive interest at a rate that is reset every week. This would
enable the Fund to offset a decline in the value of the mortgage backed
security due to rising interest rates but would also limit its ability to
benefit from falling interest rates. Conversely, if either Fund holds a
mortgage backed security with an interest rate that is reset every week and it
would like to lock in what it believes to be a high interest rate for one
year, it may swap the right to receive interest at this variable weekly rate
for the right to receive interest at a rate that is fixed for one year. Such a
swap would protect the Fund from a reduction in yield due to falling interest
rates and may permit the Fund to enhance its income through the positive
differential between one week and one year interest rates, but would preclude
it from taking full advantage of rising interest rates.

     The Funds also may engage in interest rate transactions in the form of
purchasing or selling interest rate caps or floors. The purchase of an
interest rate cap entitles the purchaser, to the extent that a specified index
exceeds a predetermined interest rate, to receive payments of interest on a
notional principal amount from the party selling such interest rate cap. The
purchase of an interest rate floor entitles the purchaser, to the extent that
a specified index falls below a predetermined interest rate, to receive
payments of interest on a notional principal amount from the party selling
such interest rate floor.

     Typically the parties with which the Funds will enter into interest rate
transactions will be broker-dealers and other financial institutions. The
Funds will enter into interest rate swap, cap or floor transactions only with
counterparties that are rated investment grade quality by at least one
nationally recognized statistical rating organization at the time of entering
into such transaction or whose creditworthiness is believed by FAM to be
equivalent to such rating. If there is a default by the other party to such a
transaction, the Funds will have contractual remedies pursuant to the
agreements related to the transaction. The swap market has grown substantially
in recent years with a large number of banks and investment banking firms
acting both as principals and as agents utilizing standardized swap
documentation. As a result, the swap market has become relatively liquid in
comparison with other similar instruments traded in the interbank market. Caps
and floors, however, are less liquid than swaps. Certain Federal income tax
requirements may limit each Fund's ability to engage in certain interest rate
transactions. Gains from transactions in interest rate swaps distributed to
stockholders will be taxable as ordinary income or, in certain circumstances,
as long term capital gains to stockholders.

     Credit Default Swap Agreements. Each of Mercury Fund and Government
Mortgage Fund may enter into credit default swap agreements. The "buyer" in a
credit default contract is obligated to pay the "seller" a periodic stream of
payments over the term of the contract provided that no credit event with
respect to an underlying reference obligation has occurred. Generally a credit
event means bankruptcy, failure to pay, obligation acceleration or modified
restructuring. If a credit event occurs, the seller typically must pay the
buyer the "par value" (full notional value) of the reference obligation in
exchange for the reference obligation. A Fund may be either the buyer or
seller in the transaction. If either Fund is a buyer and no credit event
occurs, such Fund loses its investment and recovers nothing. However, if a
credit event occurs, the buyer receives full notional value for a reference
obligation that may have little or no value. As a seller, each Fund receives a
fixed rate of income throughout the term of the contract, which typically is
between one month and five years, provided that no credit event occurs. If a
credit event occurs, the seller must pay the buyer the full notional value of
the reference obligation.

     Credit default swaps involve greater risks than if either Fund had
invested in the reference obligation directly. In addition to general market
risks, credit default swaps are subject to illiquidity risk, counterparty risk
and credit risks. The Funds will enter into swap agreements only with
counterparties who are rated investment grade quality by at least one
nationally recognized statistical rating organization at the time of entering
into such transaction or whose creditworthiness is believed by FAM to be
equivalent to such rating. A buyer also will lose its investment and recover
nothing should no credit event occur. If a credit event were to occur, the
value of the reference obligation received by the seller, coupled with the
periodic payments previously received, may be less than the full notional
value it pays to the buyer, resulting in a loss of value to such Fund.

     The Funds will only buy a credit default swap if they own the reference
obligation. If a Fund is a seller of a credit default swap, it will maintain
an amount of cash or liquid instruments having an aggregate net asset value at
least equal to the full notional value of the reference obligation in a
segregated account with the Fund's custodian. The value of these assets will
be monitored daily to ensure that their marked to market value at all times
will exceed the corresponding obligation of the Fund.

     Indexed and Inverse Floating Rate Securities. Mercury Fund and Government
Mortgage Fund may invest in securities whose potential returns are directly
related to changes in an underlying index or interest rate, known as indexed
securities. The return on indexed securities will rise when the underlying
index or interest rate rises and fall when the index or interest rate falls.
The Funds may also invest in securities whose return is inversely related to
changes in an interest rate ("inverse floaters"). In general, inverse floaters
change in value in a manner that is opposite to most bonds -- that is,
interest rates on inverse floaters will decrease when short-term rates
increase and increase when short-term rates decrease. Investments in indexed
securities and inverse floaters may subject a Fund to the risk of reduced or
eliminated interest payments. Investments in indexed securities also may
subject a Fund to loss of principal. In addition, certain indexed securities
and inverse floaters may increase or decrease in value at a greater rate than
the underlying interest rate, which effectively leverages the Fund's
investment. As a result, the market value of such securities will generally be
more volatile than that of fixed rate securities. Both indexed securities and
inverse floaters can be derivative securities and can be considered
speculative.

Other Investment Policies

     Government Mortgage Fund and Mercury Fund have adopted certain other
investment policies described below.

     When Issued Securities and Delayed Delivery Transactions. The Funds may
purchase U.S. Government securities on a when issued basis, and each may
purchase or sell U.S. Government securities for delayed delivery. These
transactions occur when securities are purchased or sold by the Fund with
payment and delivery taking place in the future to secure what is considered
an advantageous yield and price to the Fund at the time of entering into the
transaction.

     Stripped Mortgage Backed Securities. The Funds may invest in stripped
mortgage backed securities ("SMBSs") issued by agencies or instrumentalities
of the United States. SMBSs are derivative multiclass mortgage backed
securities. SMBS arrangements commonly involve two classes of securities that
receive different proportions of the interest and principal distributions on a
pool of mortgage assets. A common variety of SMBS is where one class (the
principal only or PO class) receives some of the interest and most of the
principal from the underlying assets, while the other class (the interest only
or IO class) receives most of the interest and the remainder of the principal.
In the most extreme case, the IO class receives all of the interest, while the
PO class receives all of the principal. While a Fund may purchase securities
of a PO class, it is more likely to purchase the securities of an IO class.
The yield to maturity of an IO class is extremely sensitive to the rate of
principal payments (including prepayments) on the related underlying assets,
and a rapid rate of principal payments in excess of that considered in pricing
the securities will have a material adverse effect on an IO security's yield
to maturity. If the underlying mortgage assets experience greater than
anticipated payments of principal, a Fund may fail to recoup fully its initial
investment in IOs. In addition, there are certain types of IOs which represent
the interest portion of a particular class as opposed to the interest portion
of the entire pool. The sensitivity of this type of IO to interest rate
fluctuations may be increased because of the characteristics of the principal
portion to which they relate. As a result of the above factors, a Fund
generally will purchase IOs only as a component of so called "synthetic"
securities. This means that purchases of IOs will be matched with certain
purchases of other securities, such as POs, inverse floating rate CMOs or
fixed rate securities; as interest rates fall, presenting a greater risk of
unanticipated prepayments of principal, the negative effect on a Fund because
of its holdings of IOs should be diminished somewhat because of the increased
yield on the inverse floating rate CMOs or the increased appreciation on the
POs or fixed rate securities. IOs and POs are considered by the staff of the
Commission to be illiquid securities and, consequently, the Fund will not
invest in IOs or POs in an amount which, taken together with the Fund's other
investments in illiquid securities, exceeds 15% of the Fund's net assets.

     Short Sales. The Funds may from time to time make short sales. These
transactions will involve either short sales of securities retained in a
Fund's portfolio or securities which it has the right to acquire without the
payment of further consideration (a short sale "against the box").

     Repurchase Agreements. The Funds may invest in U.S. Government securities
pursuant to repurchase agreements. Repurchase agreements may be entered into
only with a member bank of the Federal Reserve System or primary dealer in
U.S. Government securities or an affiliate thereof. Under such agreements, the
seller agrees, upon entering into the contract, to repurchase the security at
a mutually agreed upon time and price, thereby determining the yield during
the term of the agreement. This results in a fixed rate of return insulated
from market fluctuations during such period. The Funds may not invest in
repurchase agreements maturing in more than seven days if, as a result, more
than 15% of the Fund's net assets would be invested in illiquid securities,
including such repurchase agreements. In the event of default by the seller
under a repurchase agreement, such Fund may suffer time delays and incur costs
or possible losses in connection with the disposal of the collateral.

     Securities Lending. The Funds may lend portfolio securities, with a value
not in excess of 33 1/3% of its total assets, to brokers, dealers and
financial institutions and receive collateral in cash or U.S. Government
securities which will be maintained at all times in an amount equal to at
least 100% of the current market value of the loaned securities. The Funds
receive the income on the loaned securities. Where a Fund receives securities
as collateral, the Fund receives a fee for its loan from the borrower. Where a
Fund receives cash collateral, it may invest such collateral and retain the
amount earned, net of any amount rebated to the borrower. As a result, the
Fund's yield may increase. Loans of securities are terminable at any time and
the borrower, after notice is required to return



                                     -26-


borrowed securities within the standard time period for settlement of
securities transactions. The Funds may pay reasonable finder's, lending agent,
administrative and custodial fees in connection with their loans. In the event
that the borrower defaults on its obligation to return borrowed securities
because of insolvency or for any other reason, a Fund could experience delays
and costs in gaining access to the collateral. The Funds could also suffer a
loss in the event of losses on investments made with cash collateral or, in
the event of borrower default, where the value of the collateral falls below
the market value of the borrowed securities. The Funds have received an
exemptive order from the Commission permitting them to lend portfolio
securities to Merrill Lynch, Pierce, Fenner & Smith Incorporated ("Merrill
Lynch") or its affiliates, and to retain an affiliate of the Funds as lending
agent. See "Portfolio Transactions and Brokerage."

     Borrowing of Money. Except to the extent permitted by a Fund's investment
policies as set forth in its Prospectus and Statement of Additional
Information, the Fund may not borrow money to purchase portfolio securities.
However, the Funds may borrow from banks as a temporary measure for
extraordinary or emergency purposes or to meet redemptions in amounts not
exceeding 10% (taken at market value) of its total assets and pledge its
assets to secure such borrowings. The Funds will not purchase portfolio
securities while any borrowings are outstanding.

                                     -28-


Purchase of Shares

     Government Mortgage Fund and Mercury Fund each offer four classes of
shares. Government Mortgage Fund's Class A, Class D, Class B and Class C
shares are substantially the same as Mercury Fund's Class I, Class A, Class B
and Class C shares, respectively, except that the CDSC period of Class B
shares of Government Mortgage Fund is four years and the CDSC period of Class
B shares of Mercury Fund is six years, and each Fund's share classes represent
ownership interests in a different investment portfolio. For a complete
discussion of the four classes of shares and the purchase and distribution
procedures related thereto for Government Mortgage Fund and Mercury Fund, see
"Your Account--Merrill Lynch Select PricingSM System" and "--How to Buy, Sell,
Transfer and Exchange Shares" in the Government Mortgage Fund Prospectus and
"Pricing of Shares" and "How to Buy, Sell, Transfer and Exchange Shares" in
the Mercury Fund Prospectus.

Redemption of Shares

     The redemption procedures for shares of Government Mortgage Fund are the
same as the redemption procedures for shares of Mercury Fund. For purposes of
computing any CDSC that may be payable upon disposition of shares of
Government Mortgage Fund distributed to Mercury Fund stockholders in the
Reorganization, the holding period of Mercury Fund shares outstanding on the
date the Reorganization takes place will be tacked onto the holding period of
the shares of Government Mortgage Fund distributed in the Reorganization. See
"Your Account--Merrill Lynch Select PricingSM System," "--How to Buy, Sell,
Transfer and Exchange Shares" and "--Participation in Fee-Based Programs" in
the Government Mortgage Fund Prospectus and "Pricing of Shares," "How to Buy,
Sell, Transfer and Exchange Shares" and "Participation in Fee-Based Programs"
in the Mercury Fund Prospectus.

Exchange of Shares

     The exchange privilege for the Class A, Class B, Class C and Class D
shares of Government Mortgage Fund is similar to the exchange privilege for
the Class I, Class B, Class C and Class A shares of Mercury Fund,
respectively, except that Government Mortgage Fund stockholders receive shares
of other mutual funds advised by FAM or its affiliate, Merrill Lynch
Investment Managers, L.P. ("MLIM"), and Mercury Fund stockholders receive
shares of other Mercury mutual funds. Mutual funds advised by FAM or MLIM are
together referred to herein as "FAM/MLIM-advised mutual funds." U.S.
stockholders of each class of shares of Government Mortgage Fund have an
exchange privilege with certain other FAM/MLIM-advised mutual funds and Summit
Cash Reserves Fund ("Summit"), a series of Financial Institutional Series
Trust, which is a Merrill Lynch-sponsored money market fund specifically
designated for exchange by holders of Class A, Class B, Class C and Class D
shares of FAM/MLIM-advised mutual funds. Under the Merrill Lynch Select
PricingSM System, Class A stockholders may exchange Class A shares of
Government Mortgage Fund for Class A shares of a second FAM/MLIM-advised
mutual fund if the stockholder holds any Class A shares of the second fund in
his or her account in which the exchange is made at the time of the exchange
or is otherwise eligible to purchase Class A shares of the second fund. If the
Class A stockholder wants to exchange Class A shares for shares of a second
FAM/MLIM-advised mutual fund, and the stockholder does not hold Class A shares
of the second fund in his or her account at the time of the exchange and is
not otherwise eligible to acquire Class A shares of the second fund, the
stockholder will receive Class D shares of the second fund as a result of the
exchange. Class D shares also may be exchanged for Class A shares of a second
FAM/MLIM-advised mutual fund at any time as long as, at the time of the
exchange, the stockholder holds Class A shares of the second fund in the
account in which the exchange is made or is otherwise eligible to purchase
Class A shares of the second fund. Class B, Class C and Class D shares will be
exchangeable with shares of the same class of other FAM/MLIM-advised mutual
funds. For purposes of computing the CDSC that may be payable upon a
disposition of the shares acquired in the exchange, the holding period for the
previously owned shares of Government Mortgage Fund is "tacked" to the holding
period of the newly acquired shares of the other fund. Class A, Class B, Class
C and Class D shares also will be exchangeable for shares of certain
FAM/MLIM-advised mutual funds specifically designated as available for
exchange by holders of Class A, Class B, Class C or Class D shares. Shares
with a net asset value of at least $100 are required to qualify for the
exchange privilege, and any shares utilized in an exchange must have been held
by the stockholder for at least 15 days. It is contemplated that the exchange
privilege may be applicable to other new mutual funds whose shares may be
distributed by Government Mortgage Fund's distributor.



                                     -29-


     U.S. stockholders of Class I, Class A, Class B and Class C shares of
Mercury Fund have an exchange privilege with certain other Mercury mutual
funds and Summit Cash Reserves Fund. Class I stockholders may exchange Class I
shares of the Fund for Class I shares of a second Mercury mutual fund. If the
Class I stockholder wants to exchange Class I shares for shares of a second
Mercury mutual fund or for Class A shares of Summit, but does not hold Class I
shares of the second fund or Class A shares of Summit in his or her account at
the time of exchange and is not otherwise eligible to acquire Class I shares
of the second fund or Class A shares of Summit, the stockholder will receive
Class A shares of the second fund as a result of the exchange. Class A shares
also may be exchanged for Class I shares of a second Mercury mutual fund at
any time as long as, at the time of the exchange, the stockholder is eligible
to acquire Class I shares of such Mercury mutual fund. Class B and Class C
shares will be exchangeable for Class B or Class C shares, respectively, of
another Mercury mutual fund or for Class B shares of Summit. For purposes of
computing the CDSC that may be payable on a disposition of the new Class B or
Class C shares, the holding period for the outstanding Class B or Class C
shares is "tacked" to the holding period of the new Class B or Class C shares.
Class I, Class A, Class B and Class C shares also will be exchangeable for
shares of certain Mercury mutual funds specifically designated as available
for exchange by holders of Class I, Class A, Class B and Class C shares.
Shares with a net asset value of at least $100 are required to qualify for the
exchange privilege, and any shares utilized in an exchange must have been held
by the stockholder for at least 15 days.

Code of Ethics

     Each Board has approved the same Code of Ethics under Rule 17j-1 of the
Investment Company Act, which covers the Fund and the Fund's investment
adviser. The Code of Ethics establishes procedures for personal investing and
restricts certain transactions. Employees subject to the Code of Ethics may
invest in securities for their personal investment accounts, including
securities that may be purchased or held by the respective Fund.

Stockholder Rights

     Stockholders of Government Mortgage Fund are entitled to one vote for
each share held and fractional votes for fractional shares held and will vote
on the election of Board Members and any other matter submitted to a
stockholder vote. Government Mortgage Fund does not intend to hold annual
meetings of stockholders. Voting rights for Board Members are not cumulative.
Shares of Government Mortgage Fund to be issued to stockholders of the Mercury
Fund in the Reorganization will be fully paid and, except as stated below,
non-assessable, will have no preemptive rights, and will have the conversion
rights described in this Proxy Statement and Prospectus and in the Government
Mortgage Fund Prospectus. Each share of Government Mortgage Fund is entitled
to participate equally in dividends declared by the Fund and in the net assets
of the Fund on liquidation or dissolution after satisfaction of outstanding
liabilities, except that Class B, Class C and Class D shares bear certain
additional expenses. See "Stockholders' Meetings" below for additional
information. Rights attributable to shares of Mercury Fund are similar to
those described above.

Limitation of Liability

     Government Mortgage Fund is an entity of the type commonly known as a
"Massachusetts business trust." Under Massachusetts law, stockholders of such
a trust may, under certain circumstances, be held personally liable as
partners for its obligations. However, the Declaration of Trust of Government
Mortgage Fund contains an express disclaimer of stockholder liability for acts
or obligations of Government Mortgage Fund and provides for indemnification
and reimbursement of expense out of Government Mortgage Fund's property for
any stockholder held personally liable for the obligations of Government
Mortgage Fund. Thus, the risk of a stockholder incurring financial loss on
account of stockholder liability is limited to circumstances in which
Government Mortgage Fund itself would be unable to meet its obligations. Given
the nature of Government Mortgage Fund's assets and operations, the
possibility of Government Mortgage Fund being unable to meet its obligations
is remote and the risk to Government Mortgage Fund's stockholders is remote.

     The Declaration of Trust further provides that no Trustee, officer,
employee or agent of Government Mortgage Fund is liable to Government Mortgage
Fund or to any stockholder, nor is any Trustee, officer, employee or agent
liable to any third persons in connection with the affairs of Government
Mortgage Fund, except as such liability may arise from his or her own bad
faith, willful misfeasance, gross negligence, or reckless disregard of his or
her duties. It also provides that all third persons shall look solely to
Government Mortgage Fund property for satisfaction of claims arising in
connection with the affairs of Government Mortgage Fund. With the exceptions
stated, the Declaration of Trust provides that a Trustee, officer, employee or
agent is entitled to be indemnified against all liability in connection with
the affairs of Government Mortgage Fund.

Dividends

     It is the intention of each Fund to distribute substantially all of its
net investment income. Each Fund distributes dividends from net investment
income monthly. All net realized capital gains, if any, will be distributed to
each Fund's stockholders at least annually. From time to time, each Fund may
declare a special distribution at or about the end of the calendar year in
order to comply with Federal tax requirements that certain percentages of its
ordinary income and capital gains be distributed during the year.

Automatic Dividend Reinvestment Plan

     Each of Government Mortgage Fund and Mercury Fund offers its stockholders
an Automatic Dividend Reinvestment Plan (each, a "Plan" and collectively, the
"Plans") with the same terms. Pursuant to the Plans,



                                     -31-


dividends will be automatically reinvested, without sales charge, in
additional full and fractional shares of the relevant Fund unless a
stockholder has elected to receive such dividends in cash. For further
information about the Plans, see "Your Account--How to Buy, Sell, Transfer and
Exchange Shares" in the Government Mortgage Fund Prospectus and "Account
Choices--How to Buy, Sell, Transfer and Exchange Shares" in the Mercury Fund
Prospectus.

     After the Reorganization, former stockholders of Mercury Fund who elected
to receive dividends in cash will continue to receive dividends in cash from
the Combined Fund; dividends paid to all other former Mercury Fund
stockholders will be automatically reinvested in shares of the Combined Fund.
If a stockholder currently owns shares of Government Mortgage Fund and shares
of Mercury Fund, after the Reorganization that stockholder's election with
respect to the dividends of Government Mortgage Fund will control unless the
stockholder specifically elects a different option.

Tax Information

     The tax consequences associated with investment in shares of Mercury Fund
are identical to the tax consequences associated with investment in shares of
Government Mortgage Fund. See "Summary--Tax Considerations" and "The
Reorganization--Tax Consequences of the Reorganization" herein, and "Your
Account--Dividends and Taxes" in the Government Mortgage Fund Prospectus.

Portfolio Transactions

     The procedures for engaging in portfolio transactions are generally the
same for Government Mortgage Fund and Mercury Fund. After the Reorganization,
the Combined Fund will utilize the portfolio transaction procedures of
Government Mortgage Fund. For a discussion of Government Mortgage Fund's
procedures, see "Portfolio Transactions" in the Government Mortgage Fund
Statement of Additional Information.

Portfolio Turnover

     Generally, neither Government Mortgage Fund nor Mercury Fund purchases
securities for short term trading profits. Government Mortgage Fund and
Mercury Fund may dispose of securities without regard to the time that they
have been held when such action, for defensive or other reasons, appears
advisable to the Fund's investment adviser. Neither Government Mortgage Fund
nor Mercury Fund has any limit on its portfolio turnover rate. A high
portfolio turnover rate may result in negative tax consequences, such as an
increase in capital gain dividends or in ordinary income dividends
representing the excess of net short-term capital gains over net long-term
capital losses or accrued market discount. High portfolio turnover also may
involve correspondingly greater transaction costs in the form of dealer
spreads and brokerage commissions that are borne directly by the Fund. The
following table illustrates the portfolio turnover rates for the Funds for the
last two fiscal years:

  Mercury Fund                                         84.53%                                185.42%+
  ------------------------------------- -------------------------------------- --------------------------------------

   *   The fiscal year end of Government Mortgage Fund is August 31 and the
       fiscal year end of Mercury Fund is January 31.

   +   The increase in the portfolio turnover rate for each Fund shown above
       was due to a significant net inflow of assets into the Funds, change in
       interest rates and an increase in the use of purchase and sale
       contracts involving GNMA Certificates.



Additional Information

     Net Asset Value. Both Mercury Fund and Government Mortgage Fund determine
net asset value of each class of its shares once daily as of the close of
business on the NYSE on each day during which the NYSE is open



                                     -32-


for trading based on prices at the time of closing. The NYSE generally closes
at 4:00 p.m. Eastern time. Net asset value is computed by dividing the market
value of the securities held by the Fund plus any cash or other assets
(including interest and dividends accrued but not yet received) minus all
liabilities (including accrued expenses) by the total number of shares
outstanding at such time.

     Stockholder Services. Government Mortgage Fund offers a number of
stockholder services and investment plans designed to facilitate investment in
shares of the Fund. In addition, U.S. stockholders of each class of shares of
Government Mortgage Fund have an exchange privilege with certain other
FAM/MLIM-advised mutual funds. Stockholder services, including exchange
privileges, available to stockholders of Mercury Fund are similar to those of
Government Mortgage Fund, except that Mercury Fund stockholders have an
exchange privilege with certain other Mercury mutual funds. For a description
of these services, see "Investment Objectives and Policies - Exchange of
Shares" in this Proxy Statement and Prospectus and see "Shareholder Services"
in the Government Mortgage Fund Statement of Additional Information.

     Custodian. The Bank of New York ("BONY") acts as custodian of the cash
and securities for each of the Funds. BONY's principal business address is 90
Washington Street, 12th Floor, New York, New York 11286. It is anticipated
that BONY will serve as the custodian of the Combined Fund.

     Accounting Services. Each of Government Mortgage Fund and Mercury Fund
has entered into an agreement with State Street Bank and Trust Company ("State
Street") effective January 1, 2001, pursuant to which State Street provides
certain accounting services to Government Mortgage Fund and Mercury Fund.
Government Mortgage Fund and Mercury Fund each pay a fee for these services.
Prior to January 1, 2001, FAM provided accounting services to Government
Mortgage Fund and Mercury Fund and was reimbursed by each Fund at its cost in
connection with such services. FAM continues to provide certain accounting
services to Government Mortgage Fund and Mercury Fund and the Funds reimburse
FAM for these services.

     The tables below show the amounts paid by Government Mortgage Fund and
Mercury Fund to State Street and to FAM for accounting services for the
periods indicated.

     Capital Stock. Government Mortgage Fund is authorized to issue an
unlimited number of shares of beneficial interest, par value $.10 per share,
which are divided into four classes, designated Class A, Class B, Class C and
Class D shares. Asset Program is authorized to issue 200,000,000 shares of
common stock, par value $0.10 per share, of which 33,750,000 have been
designated to Mercury Fund as follows: 6,250,000 Class I shares, 6,250,000
Class A shares, 15,000,000 Class B shares and 6,250,000 Class C shares.

     The types of expenses attributable to Class A, Class B, Class C and Class
D shares of Government Mortgage Fund and Class I, Class A, Class B and Class C
shares of Mercury Fund are identical in all respects, except that at current
asset levels the management fee due from Mercury Fund would be at a higher
rate than the management fee due from Government Mortgage Fund (see
"Management -- Management and Advisory Arrangements") (however, currently FAM
is waiving the management fee due from Mercury Fund but may discontinue this
waiver at any time) and (ii) Class B shares of Mercury Fund are subject to a
longer CDSC period and a different CDSC schedule than Class B shares of
Government Mortgage Fund (see "Management -- Sales Charges; 12b-1 Fees").

     Stockholder Inquiries. Stockholder inquiries with respect to Government
Mortgage Fund and Mercury Fund may be addressed to the respective Fund by
telephone at (609) 282-2800 or at the address set forth on the cover page of
this Proxy Statement and Prospectus.

                              THE REORGANIZATION

General

     Under the Agreement and Plan (attached hereto as Exhibit I), Government
Mortgage Fund will acquire substantially all of the assets, and assume
substantially all of the liabilities, of Mercury Fund, a series of Asset
Program, in exchange solely for an equal aggregate value of newly issued
shares of beneficial interest, with a par value of $.10 per share, of
Government Mortgage Fund. Such shares of Government Mortgage Fund received by
Mercury Fund will then be distributed on a proportionate basis to the
stockholders of Mercury Fund in exchange for their shares of common stock of
Mercury Fund, with a par value of $.10 per share. These transactions are
referred to as the "Reorganization".

     Generally, the assets transferred by Mercury Fund to Government Mortgage
Fund will equal all investments of Mercury Fund held in its portfolio after
the close of business on the NYSE on the business day prior to the date the
Reorganization takes place ("Valuation Time") and all other assets of Mercury
Fund as of such time.

     Shares of Government Mortgage Fund will be distributed to stockholders of
Mercury Fund as follows: holders of Class I, A, B and C shares of Mercury Fund
who own such shares as of the Valuation Time will be entitled to receive Class
A, D, B and C shares, respectively, of Government Mortgage Fund (the
"Corresponding Shares"). The aggregate net asset value of the Corresponding
Shares of Government Mortgage Fund to be received by each stockholder of
Mercury Fund will equal the aggregate net asset value of the shares of Mercury
Fund owned by such stockholder as of the Valuation Time. See "Terms of the
Agreement and Plan -- Valuation of Assets and Liabilities" for information
concerning the calculation of net asset value.

     Since the Corresponding Shares will be issued at net asset value and the
shares of Mercury Fund will be valued at net asset value, the interests of
holders of shares of Mercury Fund will not be diluted as a result of the



                                     -34-


Reorganization. Because the Combined Fund will have a larger asset base than
Mercury Fund as a result of the Reorganization, a stockholder of Mercury Fund
likely will hold a lower percentage of ownership in the Combined Fund than he
or she did in Mercury Fund immediately prior to the Reorganization.

Procedure

     The Board of Asset Program, including all of the Board Members who are
not "interested persons" of Asset Program as defined in the Investment Company
Act, unanimously approved the Agreement and Plan and the submission of such
Agreement and Plan to the stockholders of Mercury Fund for approval. The Board
of Government Mortgage Fund, including all of the Board Members who are not
"interested persons" of the Fund, also unanimously approved the Agreement and
Plan. No vote of the stockholders of Government Mortgage Fund is required.

     If the stockholders of Mercury Fund approve the Agreement and Plan at the
Meeting, and all required regulatory approvals are obtained and certain
conditions are either met or waived, it is presently anticipated that the
Reorganization will take place as soon as practicable after such approval.

     THE BOARD OF ASSET PROGRAM RECOMMENDS THAT MERCURY FUND STOCKHOLDERS
APPROVE THE AGREEMENT AND PLAN.

Terms of the Agreement and Plan

     The following is a summary of the significant terms of the Agreement and
Plan. This summary is qualified in its entirety by reference to the Agreement
and Plan, a copy of which is attached hereto as Exhibit I.

     Valuation of Assets and Liabilities. Full shares of Government Mortgage
Fund, and to the extent necessary, fractional shares of Government Mortgage
Fund, of an aggregate net asset value equal to the value of the assets of
Mercury Fund, determined as hereinafter provided, shall be issued by
Government Mortgage Fund, in return for such assets of Mercury Fund. The
respective assets of the Funds will be valued as of the Valuation Time. The
assets of each Fund will be valued according to the procedures set forth under
"Your Account--How Shares Are Priced" in the Government Mortgage Fund
Prospectus. Such valuation and determination shall be made by Government
Mortgage Fund in cooperation with Mercury Fund. Purchase orders for Mercury
Fund shares which have not been confirmed as of the Valuation Time will be
treated as assets of Mercury Fund for purposes of the Reorganization;
redemption requests which have not settled as of the Valuation Time will be
treated as liabilities for purposes of the Reorganization.

     Distribution of Corresponding Shares. As soon as practicable after the
Closing Date (the next full business day following the Valuation Time),
Mercury Fund will liquidate and distribute the Corresponding Shares of
Government Mortgage Fund received by it pro rata to its stockholders in
exchange for such stockholders' proportional interests in Mercury Fund. The
Corresponding Shares of Government Mortgage Fund received by the stockholders
will have the same aggregate net asset value as each such stockholders'
interest in Mercury Fund held on the Closing Date. Generally, the liquidation
and distributions will be accomplished by opening new accounts on the books of
Government Mortgage Fund in the names of the stockholders of Mercury Fund and
transferring to those stockholders' accounts the shares of Government Mortgage
Fund representing such stockholders' interests in Mercury Fund.

     No sales charge or fee of any kind will be charged to stockholders of
Mercury Fund in connection with their receipt of Corresponding Shares of
Government Mortgage Fund in the Reorganization.

     Expenses. The expenses of the Reorganization that are directly
attributable to Mercury Fund are expected to include the expenses incurred in
preparing, printing and mailing the proxy materials to be utilized in
connection with the meeting of stockholders of the Fund to consider the
Reorganization, the expenses related to the solicitation of proxies to be
voted at that meeting and a portion of the expenses related to the printing of
the Proxy Statement and Prospectus and of the Reorganization Statement of
Additional Information. The expenses of the Reorganization that are directly
attributable to Mercury Fund will be borne by Mercury Fund up to a maximum of
$116,000 and by



                                     -35-


FAM in excess of that amount. The expenses for Government Mortgage Fund are
expected to include the expenses incurred in printing sufficient copies of
Government Mortgage Fund's Prospectus and Annual Report that will accompany
the mailing of the Proxy Statement and Prospectus. The expenses of the
Reorganization that are directly attributable to Government Mortgage Fund will
be borne by FAM. Certain other expenses of the Reorganization, including
expenses in connection with obtaining the opinion of counsel with respect to
certain tax matters, the preparation of the Agreement and Plan, legal,
transfer agent and audit fees, will be borne equally by Mercury Fund (up to a
maximum of $116,000 as noted above) and FAM, which has agreed to bear
Government Mortgage Fund's Reorganization expenses, and entirely by FAM to the
extent Mercury Fund's $116,000 expense cap is exceeded. The expenses of the
Reorganization attributable to Government Mortgage Fund (borne by FAM) and
Mercury Fund (borne by FAM in excess of $116,000) are currently estimated to
be approximately $86,500 and $122,900, respectively.

     Required Approvals. Consummation of the Reorganization is conditioned
upon the approval by the Board of Government Mortgage Fund and the Board of
Asset Program, as well as the receipt of certain regulatory approvals. In
addition, approval of the Agreement and Plan by Mercury Fund requires the
affirmative vote of the stockholders of Mercury Fund representing a majority
of the outstanding shares of Mercury Fund entitled to be voted thereon. All
classes of shares of Mercury Fund will vote together as a single class in
approving the Agreement and Plan. A vote of the stockholders of Government
Mortgage Fund is not required.

     Termination of Mercury Fund. Following the transfer of the assets and
liabilities of Mercury Fund to Government Mortgage Fund and distribution of
the Corresponding Shares of Government Mortgage Fund to Mercury Fund's
stockholders, Asset Program will take action to terminate Mercury Fund as a
series of Asset Program under Maryland law.

     Amendments and Conditions. The Agreement and Plan may be amended at any
time prior to the Closing Date with respect to any of the terms therein only
by agreement of all the parties to the Agreement and Plan. The obligations of
Mercury Fund and Government Mortgage Fund pursuant to the Agreement and Plan
are subject to various conditions, including a registration statement on Form
N-14 becoming effective, approval of the Reorganization by Mercury Fund's
stockholders, an opinion of counsel being received as to certain tax matters
and the continuing accuracy of various representations and warranties being
confirmed by the respective parties. The Boards may amend the Agreement and
Plan to change the terms of the Reorganization at any time prior to the
approval thereof by the shareholders of Mercury Fund.

     Termination, Postponement and Waivers. The Agreement and Plan may be
terminated, and the Reorganization abandoned at any time, whether before or
after adoption thereof by the stockholders of Mercury Fund, prior to the
Closing Date, or the Closing Date may be postponed with respect to the
Reorganization: (i) by mutual consent of the Boards of Government Mortgage and
Mercury Fund; (ii) by the Board of Mercury Fund if any condition of Mercury
Fund's obligations has not been fulfilled or waived by such Board; or (iii) by
the Board of Government Mortgage Fund if any condition of Government Mortgage
Fund's obligations with respect to the Reorganization has not been fulfilled
or waived by such Board.

Potential Benefits to Stockholders of Mercury Fund as a Result of the
Reorganization

     FAM and the Board of Mercury Fund have determined, after considering
numerous factors including the estimated costs associated with the
Reorganization, that stockholders of Mercury Fund are likely to benefit from
the Reorganization. Following the Reorganization, Mercury Fund stockholders
will remain invested in a diversified open-end fund that has substantially the
same investment objective as Mercury Fund and substantially the same sales
charges and account maintenance and distribution fees. In addition,
stockholders of Mercury Fund are likely to experience certain benefits,
including potential future economies of scale and the potential for greater
flexibility in portfolio management due to increased asset size. Also, at
current asset levels, the effective advisory fee rate for the Combined Fund
would be lower than the current contractual advisory fee rate for Mercury
Fund.

     FAM believes that the Reorganization will also benefit the stockholders
of Mercury Fund because after the Reorganization, certain fixed costs, such as
printing stockholder reports and proxy statements, legal expenses, audit fees,
registration fees, mailing costs and other expenses would be spread across a
larger asset base, thereby potentially lowering the expense ratio borne by
stockholders of Mercury Fund.

     To illustrate the potential economies of scale for Mercury Fund
stockholders, the following table sets forth the total operating expense ratio
for each class of shares both excluding and including the effect of fee
waivers, if any, as of February 28, 2002.

       about ten years after initial purchase and will no longer be subject to
       distribution fees. Class B shares of Government Mortgage Fund
       automatically convert to Class D shares about ten years after initial
       purchase and will no longer be subject to distribution fees.

   ** Assuming the Reorganization had taken place on February 28, 2002.


FAM is currently waiving receipt of management fees and/or reimbursing other
expenses due from Mercury Fund but such waiver and reimbursement may be
discontinued by FAM at any time. FAM has agreed to bear all Reorganization
expenses attributable to Mercury Fund in excess of $116,000.

     The following tables set forth the net assets of the Funds for each of
their last three fiscal year ends and as of May 31, 2002.

             Government Mortgage Fund                     Mercury Fund
       -----------------------------------     -------------------------------
       As of 8/31/99        $1,626,527,000     As of 1/31/00       $16,293,000

       As of 8/31/00        $1,348,869,000     As of 1/31/01       $25,491,000

       As of 8/31/01        $1,487,204,000     As of 1/31/02       $76,266,000

       As of 5/31/02        $1,824,167,000     As of 5/31/02       $83,858,000

     Management does not believe that Mercury Fund is likely to attract
significant assets and believes that it is likely to experience net
redemptions resulting over time in a higher operating expense ratio. As
discussed above, in the Reorganization stockholders of Mercury Fund will
benefit by continuing to be invested in an open-end fund with a similar
investment objective, a lower advisory fee and a larger asset base. FAM has
agreed to bear all Reorganization expenses attributable to Government Mortgage
Fund and all such Mercury Fund expenses in excess of $116,000.

     In approving the Reorganization, the Board of Mercury Fund determined
that the interests of existing stockholders of Mercury Fund would not be
diluted as a result of the Reorganization.

Tax Consequences of the Reorganization

     Summary. Asset Program, on behalf of Mercury Fund, and Government
Mortgage Fund will receive an opinion of counsel with respect to the
Reorganization to the effect that, among other things, neither Fund will



                                     -37-


recognize any gain or loss on the transaction, and no stockholder of Mercury
Fund will recognize any gain or loss upon receipt of shares of Government
Mortgage Fund in the Reorganization.

     General. The Reorganization has been structured with the intention that
it qualify for Federal income tax purposes as a tax-free reorganization under
Section 368(a)(1)(C) of the Code. Government Mortgage Fund and Mercury Fund
have elected and qualified for the special tax treatment afforded "regulated
investment companies" under the Code, and Government Mortgage Fund intends to
continue to so qualify after the Reorganization. The Funds will receive an
opinion of counsel to the effect that for Federal income tax purposes: (i) the
transfer by Mercury Fund of substantially all of its assets to Government
Mortgage Fund in exchange solely for shares of Government Mortgage Fund as
provided in the Agreement and Plan will constitute a reorganization within the
meaning of Section 368(a)(1)(C) of the Code, and each Fund will be deemed to
be a "party" to a reorganization within the meaning of Section 368(b); (ii) in
accordance with Section 361(a) of the Code, no gain or loss will be recognized
by Mercury Fund as a result of the transfer of its assets solely in exchange
for Government Mortgage Fund shares or on the distribution of the shares of
Government Mortgage Fund to its stockholders under Section 361(c)(1); (iii)
under Section 1032 of the Code, no gain or loss will be recognized by
Government Mortgage Fund on the receipt of assets of Mercury Fund in exchange
for Government Mortgage Fund shares; (iv) in accordance with Section 354(a)(1)
of the Code, no gain or loss will be recognized by the stockholders of Mercury
Fund on the receipt of Corresponding Shares of Government Mortgage Fund in
exchange for their shares of Mercury Fund; (v) in accordance with Section
362(b) of the Code, the tax basis of Mercury Fund's assets in the hands of
Government Mortgage Fund will be the same as the tax basis of such assets in
the hands of Mercury Fund immediately prior to the consummation of the
Reorganization; (vi) in accordance with Section 358 of the Code, immediately
after the Reorganization, the tax basis of the Corresponding Shares of
Government Mortgage Fund received by the stockholders of Mercury Fund in the
Reorganization (including fractional shares to which they may be entitled)
will be equal to the tax basis of the shares of Mercury Fund surrendered in
exchange; (vii) in accordance with Section 1223 of the Code, a stockholder's
holding period for the Corresponding Shares of Government Mortgage Fund
(including fractional shares to which they may be entitled) will be determined
by including the period for which such stockholder held Mercury Fund shares
exchanged therefor, provided that such shares were held as a capital asset;
(viii) in accordance with Section 1223 of the Code, Government Mortgage Fund's
holding period with respect to Mercury Fund's assets transferred will include
the period for which such assets were held by Mercury Fund; and (ix) pursuant
to Section 381(a) of the Code and regulations thereunder, Government Mortgage
Fund will succeed to and take into account certain tax attributes of Mercury
Fund, such as earnings and profits, capital loss carryovers and method of
accounting.

     Under Section 381(a) of the Code, Government Mortgage Fund will succeed
to and take into account certain tax attributes of Mercury Fund, including,
but not limited to, earnings and profits, any net operating loss carryovers,
any capital loss carryovers and method of accounting. The Code, however,
contains special limitations with regard to the use of net operating losses,
capital losses and other similar items in the context of certain
reorganizations, including tax-free reorganizations pursuant to Section
368(a)(1)(C) of the Code, which could reduce the benefit of these attributes
to Government Mortgage Fund. As of February 28, 2002, Mercury Fund had
unrealized losses. Government Mortgage Fund had significant undistributed net
realized capital losses and net unrealized appreciation as of the same date.
After the Reorganization, stockholders will benefit from the ability of the
Combined Fund to use realized capital losses to offset any realized capital
gains and will also share in any unrealized appreciation (and the tax
consequences on realization thereof) of the Combined Fund.

     Stockholders should consult their tax advisers regarding the effect of
the Reorganization in light of their individual circumstances. As the
foregoing relates only to Federal income tax consequences, stockholders also
should consult their tax advisers as to the foreign, state and local tax
consequences of the Reorganization.

     Status as a Regulated Investment Company. Government Mortgage Fund and
Mercury Fund have elected and qualified to be taxed as regulated investment
companies under Sections 851-855 of the Code and, after the Reorganization,
Government Mortgage Fund intends to continue to so qualify.

       incurred in connection with the Reorganization or the actual number of
       shares that would have been issued. No assurance can be given as to how
       many shares of Government Mortgage Fund the stockholders of Mercury
       Fund will receive on the date the Reorganization takes place, and the
       foregoing should not be relied upon to reflect the number of shares of
       Government Mortgage Fund that actually will be received on or after
       such date.

                                     INFORMATION CONCERNING THE SPECIAL MEETING

Date, Time and Place of Meeting

     The Meeting will be held on October 8, 2002, at the offices of Fund Asset
Management, L.P., 800 Scudders Mill Road, Plainsboro, New Jersey at 9:30 a.m.
Eastern time.

Solicitation, Revocation and Use of Proxies

     A stockholder executing and returning a proxy has the power to revoke it
at any time prior to its exercise by executing a superseding proxy or by
submitting a notice of revocation to the Secretary of Mercury Fund. Although



                                     -39-


mere attendance at the Meeting will not revoke a proxy, a stockholder present
at the Meeting may withdraw his or her proxy and vote in person.

     All shares represented by properly executed proxies, unless such proxies
previously have been revoked, will be voted at the Meeting in accordance with
the directions on the proxies; if no direction is indicated on a properly
executed proxy, such shares will be voted "FOR" approval of the Agreement and
Plan.

     It is not anticipated that any other matters will be brought before the
Meeting. If, however, any other business properly is brought before the
Meeting, proxies will be voted in accordance with the judgment of the persons
designated on such proxies.

Record Date and Outstanding Shares

     Only holders of record of shares of Mercury Fund at the close of business
on the Record Date are entitled to vote at the Meeting or any adjournment
thereof. At the close of business on the Record Date, the number of shares
issued, outstanding and entitled to vote is ___________________.

Security Ownership of Certain Beneficial Owners and Management of Government
Mortgage Fund and Mercury Fund

     At the Record Date, the Board Members and officers of Government Mortgage
Fund as a group (14 persons) owned an aggregate of less than 1% of the

     To the knowledge of Mercury Fund, as of the Record Date, except as set
forth in Exhibit II to this Proxy Statement and Prospectus, no person or
entity owned of record or beneficially 5% or more of any class of the
outstanding shares of Mercury Fund.

Voting Rights and Required Vote

     For purposes of this Proxy Statement and Prospectus, each share of each
class of Mercury Fund is entitled to one vote. Approval of the Agreement and
Plan by Mercury Fund requires the affirmative vote of the stockholders of
Mercury Fund representing a majority of the outstanding shares of Mercury Fund
entitled to be voted thereon. All classes of shares of Mercury Fund will vote
together as a single class in approving the Agreement and Plan. A vote of the
stockholders of Government Mortgage Fund is not required.

     Stockholders of Mercury Fund are not entitled to demand the fair value of
their shares upon a transfer of assets and will be bound by the terms of the
Reorganization if approved at the Meeting. However, any stockholder of Mercury
Fund may redeem his or her respective shares prior to the Reorganization.

     A quorum for purposes of the Meeting consists of a majority of the shares
of Mercury Fund entitled to vote at the Meeting, present in person or by
proxy. If, by the time scheduled for the Meeting, a quorum of the stockholders
of Mercury Fund is not present or if a quorum is present but sufficient votes
in favor of the Agreement and Plan are not received from the stockholders of
Mercury Fund, the persons named as proxies may propose one or more
adjournments of the Meeting to permit further solicitation of proxies from
stockholders. Any such adjournment will require the affirmative vote of a
majority of the shares of Mercury Fund present in person or by proxy and
entitled to vote at the session of the Meeting to be adjourned. The persons
named as proxies will vote in



                                     -40-


favor of any such adjournment if they determine that adjournment and
additional solicitation are reasonable and in the interests of Mercury Fund's
stockholders.

                            ADDITIONAL INFORMATION

     The expenses of preparation, printing and mailing of the enclosed form of
proxy, the accompanying Notice and this Proxy Statement and Prospectus will be
borne by Mercury Fund up to $116,000 and by FAM beyond that amount. FAM will
reimburse banks, brokers and others for their reasonable expenses in
forwarding proxy solicitation materials to the beneficial owners of shares of
Mercury Fund and will reimburse certain persons that the Fund may employ for
their reasonable expenses in assisting in the solicitation of proxies from
such beneficial owners of shares of the Fund. See "The Reorganization - Terms
of the Agreement and Plan of Reorganization - Expenses."

     In order to obtain the necessary quorum at the Meeting, supplementary
solicitation may be made by mail, telephone, telegraph or personal interview
by officers of Mercury Fund. Mercury Fund has retained Georgeson Shareholder
Communications, Inc., with offices at 17 State Street, New York, New York
10004, to aid in the solicitation of proxies at a cost of approximately $     ,
plus out-of-pocket expenses, which are estimated to be $____.

     Broker-dealer firms, including Merrill Lynch, holding shares of Mercury
Fund in "street name" for the benefit of their customers and clients will
request the instructions of such customers and clients on how to vote their
shares before the Meeting. Broker-dealer firms, including Merrill Lynch, will
not be permitted to vote without instructions with respect to the approval of
the Agreement and Plan. Properly executed proxies that are returned but which
are marked "abstain" or with respect to which a broker-dealer has received no
instructions and therefore has declined to vote on the proposal ("broker
non-votes") will be counted as present for the purposes of determining a
quorum. However, such abstentions and broker non-votes will have the same
effect as a vote against approval of the Agreement and Plan.

     This Proxy Statement and Prospectus does not contain all of the
information set forth in the registration statements and the exhibits relating
thereto which the Funds have filed with the Commission under the Securities
Act and the Investment Company Act, to which reference is hereby made.

     Each Fund files reports and other information with the Commission.
Reports, proxy statements, registration statements and other information filed
by each Fund can be inspected and copied at the public reference facilities of
the Commission at Room 1024, Judiciary Plaza, 450 Fifth Street, N.W.,

Washington, D.C. 20549, at prescribed rates. The Commission maintains a Web
site at http://www.sec.gov containing reports, proxy and information
statements and other information regarding registrants, including the Funds,
that file electronically with the Commission.

                            STOCKHOLDERS' MEETINGS

     Stockholders of Mercury Fund are entitled to one vote for each share held
and fractional votes for fractional shares held and will vote on any matter
submitted to a stockholder vote. As a Maryland corporation, Mercury Fund does
not intend to hold meetings of stockholders in any year in which the
Investment Company Act does not require stockholders to act upon any of the
following matters: (i) election of Board Members; (ii) approval of a
management agreement; or (iii) approval of distribution arrangements. The
Charter of Mercury Fund does not require it to hold an annual meeting of
stockholders. Mercury Fund will be required, however, to call special meetings
of its stockholders in accordance with the requirements of the Investment
Company Act to seek approval of new management and advisory arrangements or of
a change in the fundamental policies, objectives or restrictions. Mercury Fund
also would be required to hold a stockholders' meeting to elect new Board
Members at such time as less than a majority of the Board Members holding
office have been elected by stockholders. The by-laws of Mercury Fund provide
that a stockholders' meeting may be called with respect to Mercury Fund at any
time by a majority of the Board Members, the President, or on the written
request of the holders of at least 10% of the outstanding capital stock of
Mercury Fund entitled to vote at such meeting.

     Stockholders of Government Mortgage Fund are entitled to one vote for
each share held and entitled to vote on any matter submitted to a stockholder
vote. There normally will be no meetings of stockholders for the purposes of
electing Board Members unless and until such time as less than a majority of
the Board Members holding office have been elected by stockholders, at which
time the Board Members then in office will call a stockholders' meeting for
the election of Board Members. The Charter of Government Mortgage Fund
provides that a stockholders' meeting may be called with respect to Government
Mortgage Fund at any time by a majority of the Board Members and shall be
called on the written request of the holders of at least 10% of the
outstanding shares of Government Mortgage Fund having voting rights.
Stockholders may, in accordance with the terms of the Charter, cause a meeting
of stockholders to be held for the purpose of voting on the removal of Board
Members. Also, Government Mortgage Fund will be required to call a special
meeting of stockholders 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 Government Mortgage Fund.

                             STOCKHOLDER PROPOSALS

     A stockholder proposal intended to be presented at any subsequent
meetings of stockholders of Mercury Fund must be received by Mercury Fund
within a reasonable time before the solicitation relating to such meeting is
to be made by the Board of Mercury Fund in order to be considered in Mercury
Fund's proxy statement and form of proxy relating to the meeting. The persons
named as proxies in any future proxy materials of Mercury Fund may exercise
discretionary authority with respect to any stockholder proposal presented at
any subsequent meeting of the stockholders of Mercury Fund if written notice
of such proposal has not been received by Mercury Fund within a reasonable
time before Mercury Fund begins to print and mail the proxy solicitation
materials to be used in connection with such meeting. Written proposals with
regard to Mercury Fund should be sent to the Secretary of the Fund, 800
Scudders Mill Road, Plainsboro, New Jersey 08536. If the Reorganization is
approved, the Meeting will be the last meeting for Mercury Fund's
stockholders.

                                                                   EXHIBIT I

                     AGREEMENT AND PLAN OF REORGANIZATION

     THIS AGREEMENT AND PLAN OF REORGANIZATION ("Agreement") is made as of the
     day of           , 2002, by and between Merrill Lynch U.S. Government
Mortgage Fund, a Massachusetts business trust ("Government Mortgage Fund"), and
The Asset Program, Inc., a Maryland corporation ("Asset Program").

                            PLAN OF REORGANIZATION

     The reorganization will comprise the acquisition by Government Mortgage
Fund of substantially all of the assets, and the assumption by Government
Mortgage Fund of substantially all of the liabilities, of Mercury U.S.
Government Securities Fund ("Mercury Fund"), a series of Asset Program, (2)
the issuance by Government Mortgage Fund of shares of beneficial interest,
with a par value of $.10 per share, of Government Mortgage Fund to Mercury
Fund with an aggregate net asset value equal to the value of the assets
acquired by Government Mortgage Fund, reduced by the amount of liabilities
assumed by Government Mortgage Fund, and (3) the subsequent distribution of
Corresponding Shares (defined below) of Government Mortgage Fund to Mercury
Fund shareholders in proportion to such shareholders' interest in Mercury
Fund.

     The transaction described above will be referred to herein as the
"Reorganization." Asset Program and Mercury Fund are sometimes referred to
herein as "Mercury Fund;" Mercury Fund and Government Mortgage Fund are
sometimes referred to herein collectively as the "Funds." Asset Program is
organized as a Maryland corporation and Government Mortgage Fund is organized
as a Massachusetts business trust. In each jurisdiction, nomenclature varies.
As used herein, shares of common stock of Mercury Fund and shares of
beneficial interest of Government Mortgage Fund are referred to as "shares" or
"Common Stock," holders of shares or Common Stock are referred to as
"shareholders," the Board of Trustees of Government Mortgage Fund and the
Board of Directors of Asset Program are each referred to as a "Board" and the
Directors or Trustees of each Fund are referred to as "Board Members."

     In the course of the Reorganization, shares of Government Mortgage Fund
will be distributed to shareholders of Mercury Fund as follows: holders of
Class I, A, B and C shares of Mercury Fund who own such shares as of the
Valuation Time (as defined in Section 3(c) of this Agreement) will be entitled
to receive Class A, D, B and C shares, respectively, of Government Mortgage
Fund (the "Corresponding Shares"). The aggregate net asset value of the
Corresponding Shares of Government Mortgage Fund to be received by each
shareholder of Mercury Fund will equal the aggregate net asset value of the
shares of Mercury Fund owned by such shareholder as of the Valuation Time. In
consideration therefor, on the Closing Date (as defined in Section 7 of this
Agreement), Government Mortgage Fund shall acquire substantially all of the
assets of Mercury Fund and assume substantially all of Mercury Fund's
obligations and liabilities then existing, whether absolute, accrued,
contingent or otherwise. It is intended that the Reorganization described in
this Plan shall be a reorganization within the meaning of Section 368(a)(1)(C)
of the Internal Revenue Code of 1986, as amended (the "Code"), and any
successor provision.



                                     I-1


     As promptly as practicable after the consummation of the Reorganization,
the Board of Asset Program shall take such action necessary to terminate
Mercury Fund as a series of Asset Program in accordance with the laws of the
State of Maryland.

                                   AGREEMENT

     In order to consummate the Reorganization and in consideration of the
premises and the covenants and agreements hereinafter set forth, and intending
to be legally bound, Government Mortgage Fund and Asset Program, on behalf of
Mercury Fund, hereby agree as follows:

     1. Representations and Warranties of Asset Program.

     Asset Program, on behalf of Mercury Fund, represents and warrants to, and
agrees with Government Mortgage Fund that:

          (a) Asset Program is a corporation duly organized, validly existing
     and in good standing in conformity with the laws of the State of
     Maryland, and has the power to own all of its assets and to carry out
     this Agreement. Mercury Fund is a duly authorized series of Asset
     Program. Asset Program has all necessary Federal, state and local
     authorizations to carry on its business as it is now being conducted and
     to carry out this Agreement.

          (b) Asset Program is duly registered under the Investment Company
     Act of 1940, as amended (the "1940 Act") as an open-end management
     investment company (File No. 811-7177), and such registration has not
     been revoked or rescinded and is in full force and effect. Asset Program
     has elected and qualified Mercury Fund at all times since its inception
     for the special tax treatment afforded regulated investment companies
     ("RICs") under Sections 851-855 of the Code and intends to continue to so
     qualify Mercury Fund through its taxable year ending upon liquidation.

          (c) As used in this Agreement, the term "Mercury Fund Investments"
     shall mean (i) the investments of Mercury Fund shown on the schedule of
     its investments as of the Valuation Time (as defined in Section 3(c) of
     this Agreement) furnished to Government Mortgage Fund pursuant to
     Sections 1(e) and 9(b); and (ii) all other assets owned by Mercury Fund
     or liabilities existing as of the Valuation Time.

          (d) Asset Program has full power and authority to enter into and
     perform its obligations under this Agreement. The execution, delivery and
     performance of this Agreement has been duly authorized by all necessary
     action of its Board, and this Agreement constitutes a valid and binding
     contract enforceable in accordance with its terms, subject to the effects
     of bankruptcy, insolvency, moratorium, fraudulent conveyance and similar
     laws relating to or affecting creditors' rights generally and court
     decisions with respect thereto.

          (e) Government Mortgage Fund has been furnished with a statement of
     assets and liabilities and a schedule of investments of Mercury Fund,
     each as of January 31, 2002, said financial statements having been
     examined by Deloitte & Touche LLP, independent public accountants. An
     unaudited statement of assets and liabilities of



                                     I-2


     Mercury Fund and an unaudited schedule of investments of Mercury Fund,
     each as of the Valuation Time, will be furnished to Government Mortgage
     Fund at or prior to the Closing Date for the purpose of determining the
     number of shares of Government Mortgage Fund to be issued pursuant to
     Section 4 of this Agreement; and each will fairly present the financial
     position of Mercury Fund as of the Valuation Time in conformity with
     generally accepted accounting principles applied on a consistent basis.

          (f) Government Mortgage Fund has been furnished with Mercury Fund's
     Annual Report for the year ended January 31, 2002, and any subsequent
     Semi-Annual Report which may be available, and the financial statements
     appearing in such reports fairly present the financial position of
     Mercury Fund as of the respective dates indicated, in conformity with
     generally accepted accounting principles applied on a consistent basis.

          (g) Government Mortgage Fund has been furnished with the prospectus
     and statement of additional information of Asset Program with respect to
     Mercury Fund, each dated May 29, 2002, and said prospectus and statement
     of additional information do not contain any untrue statement of a
     material fact or omit to state any material fact necessary to make the
     statements therein, in the light of the circumstances under which they
     were made, not misleading.

          (h) There are no material legal, administrative or other proceedings
     pending or, to the knowledge of Asset Program, threatened against it or
     Mercury Fund which assert liability on the part of Asset Program or
     Mercury Fund, which materially affect their financial condition or its
     ability to consummate the Reorganization. Neither Asset Program nor
     Mercury Fund is charged with nor, to the best of the knowledge of Asset
     Program, threatened with any violation or investigation of any possible
     violation of any provisions of any Federal, state or local law or
     regulation or administrative ruling relating to any aspect of its
     business.

          (i) There are no material contracts outstanding relating to Mercury
     Fund to which Asset Program is a party that have not been disclosed in
     the N-14 Registration Statement (as defined in subsection (o) below) or
     will not otherwise be disclosed to Government Mortgage Fund prior to the
     Valuation Time.

          (j) Asset Program is not a party to or obligated under any contract
     or other commitment or obligation, and is not subject to any order or
     decree, and there is no provision of its Articles of Incorporation, as
     amended or supplemented, or its by-laws, as amended, which would be
     violated by its execution of or performance under this Agreement.

          (k) Mercury Fund has no liabilities known to Mercury Fund or Asset
     Program of a material amount, contingent or otherwise, other than those
     shown on its statement of assets and liabilities as of January 31, 2002
     referred to above, those incurred in the ordinary course of its business
     as an investment company since the date of its most recent Annual or
     Semi-Annual Report, and those incurred in connection with the
     Reorganization. As of the Valuation Time, Asset Program will advise
     Government



                                     I-3


     Mortgage Fund in writing of all known liabilities, contingent or
     otherwise, whether or not incurred in the ordinary course of business,
     existing or accrued as of such time with respect to Mercury Fund.

          (l) Asset Program has filed, or has obtained extensions to file, all
     Federal, state and local tax returns which are required to be filed by it
     on behalf of Mercury Fund, and has paid or has obtained extensions to
     pay, all Federal, state and local taxes shown on said returns to be due
     and owing and all assessments received by it, up to and including the
     taxable year in which the Closing Date occurs. All tax liabilities of
     Mercury Fund have been adequately provided for on its books, and no tax
     deficiency or liability of Mercury Fund has been asserted and no question
     with respect thereto has been raised by the Internal Revenue Service or
     by any state or local tax authority for taxes in excess of those already
     paid, up to and including the taxable year in which the Closing Date
     occurs.

          (m) At both the Valuation Time and the Closing Date, Asset Program
     will have full right, power and authority to sell, assign, transfer and
     deliver the Mercury Fund Investments. At the Closing Date, Asset Program
     will have good and marketable title to all of the Mercury Fund
     Investments, and Government Mortgage Fund will acquire, subject only to
     the delivery of the Mercury Fund Investments as contemplated by this
     Agreement, all of the Mercury Fund Investments free and clear of any
     encumbrances, liens or security interests and without any restrictions
     upon the transfer thereof (except those imposed by the Federal or state
     securities laws and those imperfections of title or encumbrances as do
     not materially detract from the value or use of the Mercury Fund
     Investments or materially affect title thereto).

          (n) No consent, approval, authorization or order of any court or
     governmental authority is required for the consummation by Asset Program
     of the Reorganization, except such as may be required under the
     Securities Act of 1933, as amended (the "1933 Act"), the Securities
     Exchange Act of 1934, as amended (the "1934 Act"), and the 1940 Act, or
     state securities laws (which term as used herein shall include the laws
     of the District of Columbia and Puerto Rico).

     Form N-14 relating to the shares of Government Mortgage Fund to be issued

     Fund and the prospectus and statement of additional information of

     statement of a material fact or omit to state any material fact necessary

                                     I-4


     statements therein, in the light of the circumstances under which they
     were made, not misleading; provided, however, that the representations
     and warranties in this subsection shall apply only to statements in or
     omissions from the N-14 Registration Statement made in reliance upon and
     in conformity with information furnished by Mercury Fund for use in the

     Fund made available to Government Mortgage Fund and/or its counsel are
     substantially true and correct and contain no material misstatements or
     omissions with respect to the operations of Mercury Fund.

          (r) Mercury Fund will not sell or otherwise dispose of any of the
     shares of Government Mortgage Fund to be received in the Reorganization,
     except in distribution to its shareholders as provided herein.

          (s) Mercury Fund has no plan or intention to sell or otherwise

     3. The Reorganization.

          (a) Subject to receiving the requisite approval of the shareholders
     of Mercury Fund, and to the other terms and conditions contained herein,
     Mercury Fund agrees to convey, transfer and deliver to Government
     Mortgage Fund for the benefit of Government Mortgage Fund, and Government
     Mortgage Fund agrees to acquire from Mercury Fund for the benefit of
     Government Mortgage Fund, on the Closing Date all of the Mercury Fund
     Investments (including interest accrued as of the Valuation Time on debt
     instruments) of Mercury Fund, and assume substantially all of the
     liabilities of Mercury Fund, in exchange solely for that number of shares
     of Government Mortgage Fund provided in Section 4 of this Agreement.
     Pursuant to this Agreement, as soon as practicable on or after the
     Closing Date, Mercury Fund will distribute all Government Mortgage Fund
     shares received by it to its shareholders in proportion to their
     interests in Mercury Fund. Such distribution shall be accomplished by the
     opening of shareholder accounts on the stock ledger records of Government
     Mortgage Fund in the amounts due the shareholders of Mercury Fund based
     on their respective holdings in Mercury Fund as of the Valuation Time.

          (b) Mercury Fund will pay or cause to be paid to Government Mortgage
     Fund any interest it receives on or after the Closing Date with respect
     to Mercury Fund Investments transferred to Government Mortgage Fund
     hereunder.

          (c) The Valuation Time shall be 4:00 p.m. New York time, on , 2002,
     or such earlier or later day and time as may be mutually agreed upon in
     writing (the "Valuation Time"). As used herein, the term Valuation Time
     shall mean the date and time stated in the preceding sentence or if
     Mercury Fund does not obtain the required vote of its shareholders prior
     to the stated date and time, such later date and time as may be agreed
     upon by Mercury Fund and Government Mortgage Fund.

          (d) Government Mortgage Fund will acquire substantially all of the
     assets of, and assume substantially all of the liabilities of, Mercury
     Fund, except that recourse for such liabilities will be limited
     substantially to the net assets of Mercury Fund acquired by Government
     Mortgage Fund. The known liabilities of Mercury Fund as of the Valuation



                                     I-8


     Time shall be confirmed in writing to Government Mortgage Fund by Mercury
     Fund pursuant to Section 1(k) of this Agreement.

          (e) Following the distribution referred to in Section 4 above,
     Mercury Fund shall be terminated by Asset Program as a series of Asset
     Program by such action as may be necessary in accordance with the laws of
     the State of Maryland.

     4. Issuance and Valuation of Government Mortgage Fund Shares in the
        Reorganization.

     Full shares of Government Mortgage Fund, and to the extent necessary, any
fractional shares of Government Mortgage Fund, of an aggregate net asset value
equal to the value of the assets of Mercury Fund acquired, determined as
hereinafter provided, reduced by the amount of liabilities of Mercury Fund
assumed by Government Mortgage Fund, shall be issued by Government Mortgage
Fund in exchange for such assets of Mercury Fund. The net asset value of each
of Mercury Fund and Government Mortgage Fund shall be determined as of the
Valuation Time in accordance with the procedures described in the prospectus
of Government Mortgage Fund in effect as of the Valuation Time. Such valuation
and determination shall be made by Government Mortgage Fund in cooperation
with Mercury Fund. Government Mortgage Fund shall issue its Class A, Class B,
Class C and Class D shares to Mercury Fund in certificates or share deposit
receipts (one in respect of each Class) registered in the name of Mercury
Fund. Mercury Fund shall distribute Corresponding Shares of Government
Mortgage Fund to its shareholders by redelivering such certificates or
receipts to Financial Data Services, Inc.

     5. Payment of Expenses.

          (a) The expenses of the Reorganization that are directly
     attributable to Mercury Fund are expected to include the expenses
     incurred in preparing, printing and mailing the proxy materials to be
     utilized in connection with the meeting of shareholders of Mercury Fund
     to consider the Reorganization, the expenses related to the solicitation
     of proxies to be voted at that meeting and the expenses related to the
     printing of the Proxy Statement and Prospectus. The expenses of the
     Reorganization that are directly attributable to Mercury Fund will be
     borne by Mercury Fund up to $116,000, and expenses exceeding such amount
     will be borne by Fund Asset Management, L.P. ("FAM"). The expenses of the
     Reorganization that are directly attributable to Government Mortgage Fund
     are expected to include the expenses incurred in printing sufficient
     copies of Government Mortgage Fund's prospectus and annual report that
     will accompany the mailing of the Proxy Statement and Prospectus. The
     expenses of the Reorganization that are directly attributable to
     Government Mortgage Fund will be borne by FAM. Certain other expenses of
     the Reorganization, including expenses in connection with obtaining the
     opinion of counsel with respect to certain tax matters, the preparation
     of this Agreement, legal, transfer agent and audit fees, will be borne
     equally by Mercury Fund and FAM, which has agreed to bear Government
     Mortgage Fund's expenses of the Reorganization, and entirely by FAM to
     the extent Mercury Fund's $116,000 expense cap is exceeded.



                                     I-9


          (b) If for any reason the Reorganization is not consummated, no
     party shall be liable to any other party for any damages resulting
     therefrom, including, without limitation, consequential damages.

     6. Covenants of the Funds.

          (a) Mercury Fund agrees to call a special meeting of its
     shareholders to be held as soon as is practicable after the effective
     date of the N-14 Registration Statement for the purpose of considering
     the Reorganization as described in this Agreement, and it shall be a
     condition to the obligations of Government Mortgage Fund and Mercury Fund
     that the holders of a majority of the shares of Mercury Fund issued and
     outstanding and entitled to vote thereon, shall have approved this
     Agreement at such special meeting at or prior to the Valuation Time.

          (b) Each Fund covenants to operate its respective business as
     presently conducted between the date hereof and the Closing Date.

          (c) (i) Asset Program agrees that following the consummation of the
     Reorganization it will take such action as may be necessary to terminate
     Mercury Fund as a series of Asset Program in accordance with the laws of
     the State of Maryland, and (ii) Mercury Fund will not make any
     distributions of any Government Mortgage Fund shares other than to its
     shareholders and without first paying or adequately providing for the
     payment of all of its liabilities not assumed by Government Mortgage
     Fund, if any, and on and after the Closing Date shall not conduct any
     business except in connection with its termination.

          (d) Government Mortgage Fund will file the N-14 Registration
     Statement with the Securities and Exchange Commission (the "Commission")
     and will use its best efforts to provide that the N-14 Registration
     Statement becomes effective as promptly as practicable. Mercury Fund and
     Government Mortgage Fund agree to cooperate fully with each other, and
     each will furnish to the other the information relating to itself to be
     set forth in the N-14 Registration Statement as required by the 1933 Act,
     the 1934 Act, the 1940 Act, and the rules and regulations thereunder and
     the state securities laws.

          (e) Mercury Fund and Government Mortgage Fund each agree that by the
     Closing Date all of their Federal and other tax returns and reports
     required to be filed on or before such date shall have been filed and all
     taxes shown as due on said returns either have been paid or adequate
     liability reserves have been provided for the payment of such taxes. In
     connection with this covenant, Government Mortgage Fund and Mercury Fund
     agree to cooperate with each other in filing any tax return, amended
     return or claim for refund, determining a liability for taxes or a right
     to a refund of taxes or participating in or conducting any audit or other
     proceeding in respect of taxes. Government Mortgage Fund agrees to retain
     for a period of ten (10) years following the Closing Date all returns,
     schedules and work papers and all material records or other documents
     relating to tax matters of Mercury Fund for its taxable period first
     ending after the Closing Date and for all prior taxable periods. Any
     information obtained under this subsection shall be kept confidential
     except as otherwise may be necessary in connection with the filing of
     returns



                                     I-10


     or claims for refund or in conducting an audit or other proceeding. After
     the Closing Date, Mercury Fund shall prepare, or cause its agents to
     prepare, any Federal, state or local tax returns, including any Forms
     1099, required to be filed by or with respect to it with respect to its
     final taxable year ending with its complete liquidation and for any prior
     periods or taxable years and further shall cause such tax returns and
     Forms 1099 to be duly filed with the appropriate taxing authorities.
     Notwithstanding the aforementioned provisions of this subsection, Mercury
     Fund shall bear any expenses incurred by it (other than for payment of
     taxes) in connection with the preparation and filing of said tax returns
     and Forms 1099 after the Closing Date to the extent that Mercury Fund
     accrued such expenses in the ordinary course without regard to the
     Reorganization; any excess expenses shall be borne by FAM at the time
     such tax returns and Forms 1099 are prepared.

          (f) Mercury Fund agrees to mail to its shareholders of record
     entitled to vote at the special meeting of shareholders at which action
     is to be considered regarding this Agreement, in sufficient time to
     comply with requirements as to notice thereof, a combined Proxy Statement
     and Prospectus which complies in all material respects with the
     applicable provisions of Section 14(a) of the 1934 Act and Section 20(a)
     of the 1940 Act, and the rules and regulations, respectively, thereunder.

          (g) Government Mortgage Fund has no plan or intention to sell or
     otherwise dispose of the assets of Mercury Fund to be acquired in the
     Reorganization, except for dispositions made in the ordinary course of
     business.

          (h) Following the consummation of the Reorganization, Government
     Mortgage Fund expects to stay in existence and continue its business as
     an open-end management investment company registered under the 1940 Act.

     7. Closing Date.

          (a) Delivery of the assets of Mercury Fund to be transferred,
     together with any other Mercury Fund Investments, and the Government
     Mortgage Fund shares to be issued to Mercury Fund, shall be made at the

     account with The Bank of New York at the earliest practicable date
     thereafter.

          (b) Mercury Fund will deliver to Government Mortgage Fund on the

                                     I-11


          (c) As soon as practicable after the close of business on the

     Time, certified on Government Mortgage Fund's behalf by its President (or
     any Vice President) and its Treasurer, and a certificate signed by
     Government Mortgage Fund's President (or any Vice President) and its
     Treasurer, dated as of the Closing Date, certifying that as of the
     Valuation Time and as of the Closing Date there has been no material
     adverse change in the financial position of Government Mortgage Fund
     since the date of Government Mortgage Fund's most recent Annual or
     Semi-Annual Report as applicable, other than changes in its portfolio
     securities since that date or changes in the market value of its
     portfolio securities.

          (c) That Government Mortgage Fund shall have furnished to Mercury
     Fund a certificate signed by Government Mortgage Fund's President (or any
     Vice President) and its Treasurer, dated as of the Closing Date,
     certifying that, as of the Valuation Time and as of the Closing Date all
     representations and warranties of Government Mortgage Fund made in this
     Agreement are true and correct in all material respects with the same
     effect as if made at and as of such dates, and that Government Mortgage
     Fund has complied with all of the agreements and satisfied all of the
     conditions on its part to be performed or satisfied at or prior to each
     of such dates.

          (d) That there shall not be any material litigation pending with
     respect to the matters contemplated by this Agreement.

          (e) That Mercury Fund shall have received an opinion of Bingham
     McCutchen LLP, as Massachusetts counsel to Government Mortgage Fund, in
     form satisfactory to Mercury Fund and dated the Closing Date, to the
     effect that (i)



                                     I-12


     Government Mortgage Fund is a trust with transferable shares of
     beneficial interest, validly existing in conformity with the laws of the
     Commonwealth of Massachusetts and duly authorized to transact business in
     the Commonwealth of Massachusetts; (ii) the Corresponding Shares of
     Government Mortgage Fund to be issued pursuant to this Agreement are duly
     authorized and, upon delivery in accordance with the terms of this
     Agreement, will be validly issued and outstanding and fully paid and
     nonassessable by Government Mortgage Fund, except that shareholders of
     Government Mortgage Fund may under certain circumstances be held
     personally liable for Government Mortgage Fund's obligations, and no
     shareholder of Government Mortgage Fund has any preemptive right to
     subscription or purchase in respect thereof (pursuant to the Declaration
     of Trust, as amended, or the by-laws of Government Mortgage Fund or, to
     the best of such counsel's knowledge, the law of the Commonwealth of
     Massachusetts); (iii) this Agreement, to the extent Massachusetts law
     applies, has been duly authorized and executed by Government Mortgage
     Fund; (iv) the execution and delivery of this Agreement by Government
     Mortgage Fund and the consummation of the Reorganization in accordance
     with the terms of this Agreement will not violate any material provisions
     of the Declaration of Trust, as amended, or the by-laws, as amended, of
     Government Mortgage Fund, or to the best of such counsel's knowledge,
     Massachusetts law; (v) to the best of such counsel's knowledge, no
     consent, approval, authorization or order of any Massachusetts state
     court or governmental authority is required for the consummation by
     Government Mortgage Fund of the Reorganization in accordance with the
     terms of this Agreement, except such as may be required under
     Massachusetts state securities laws about which such counsel need not
     express an opinion. In giving the opinion set forth above, Bingham Dana
     LLP may state that it is relying on certificates of officers of
     Government Mortgage Fund with regard to matters of fact and certain
     certificates and written statements of governmental officials with
     respect to the good standing of Government Mortgage Fund.

          (f) That Mercury Fund shall have received an opinion of Sidley
     Austin Brown & Wood LLP, as counsel to Government Mortgage Fund, in form
     and substance satisfactory to Mercury Fund and dated the Closing Date, to
     the effect that (i) this Agreement represents a valid and binding
     contract of Government Mortgage Fund, enforceable in accordance with its
     terms, except as enforceability may be limited by bankruptcy, insolvency,
     moratorium, fraudulent conveyance and similar laws relating to or
     affecting creditors' rights generally and court decisions with respect
     thereto; provided, such counsel shall express no opinion with respect to
     the application of equitable principles in any proceeding, whether at law
     or in equity; (ii) the execution and delivery of this Agreement by
     Government Mortgage Fund does not, and the consummation of the
     Reorganization will not, violate any material provisions of any agreement
     (known to such counsel) to which Government Mortgage Fund is a party or
     by which Government Mortgage Fund is bound, except insofar as the parties
     have agreed to amend such provision as a condition precedent to the
     Reorganization; (iii) to the best of such counsel's knowledge, no
     consent, approval, authorization or order of any United States federal
     court or governmental authority is required for the consummation by
     Government Mortgage Fund of the Reorganization, except such as have been
     obtained under the 1933 Act, the 1934 Act and the 1940 Act and the
     published rules and regulations of the Commission thereunder and such as
     may be required under state securities laws; (iv) the



                                     I-13


     N-14 Registration Statement has become effective under the 1933 Act, no
     stop order suspending the effectiveness of the N-14 Registration
     Statement has been issued and no proceedings for that purpose have been
     instituted or are pending or contemplated under the 1933 Act, and the
     N-14 Registration Statement, as of the effective date, appears on its
     face to be appropriately responsive in all material respects to the
     requirements of the 1933 Act, the 1934 Act and the 1940 Act and the
     published rules and regulations of the Commission thereunder insofar as
     they relate to Government Mortgage Fund; (v) the descriptions in the N-14
     Registration Statement of statutes, legal and governmental proceedings
     and contracts and other documents insofar as they relate to Government
     Mortgage Fund are accurate and fairly present the information required to
     be shown; (vi) the information in the Proxy Statement and Prospectus
     under "Comparison of the Funds--Tax Considerations" and "The
     Reorganization--Tax Consequences of the Reorganization," to the extent
     that it constitutes matters of law, summaries of legal matters or legal
     conclusions, has been reviewed by such counsel and is correct in all
     material respects as of the date of the Proxy Statement and Prospectus;
     (vii) such counsel does not know of any statutes, legal or governmental
     proceedings or contracts or other documents related to the Reorganization
     insofar as they relate to Government Mortgage Fund of a character
     required to be described in the N-14 Registration Statement which are not
     described therein or, if required to be filed, filed as required; (viii)
     Government Mortgage Fund, to the knowledge of such counsel, is not
     required to qualify to do business as a foreign entity in any
     jurisdiction except as may be required by state securities laws, and
     except where it has so qualified or the failure so to qualify would not
     have a material adverse effect on Government Mortgage Fund or its
     shareholders; (ix) such counsel does not have actual knowledge of any
     material suit, action or legal or administrative proceeding pending or
     threatened against Government Mortgage Fund, the unfavorable outcome of
     which would materially and adversely affect Government Mortgage Fund; (x)
     all actions required to be taken by Government Mortgage Fund to authorize
     this Agreement and to effect the Reorganization have been duly authorized
     by all necessary actions on the part of such Fund; and (xi) such opinion
     is solely for the benefit of Mercury Fund and its Board Members and
     officers. Such opinion also shall state that (A) while such counsel
     cannot make any representation as to the accuracy or completeness of
     statements of fact in the N-14 Registration Statement, nothing has come
     to their attention that has caused them to believe that, on the effective
     date of the N-14 Registration Statement, (1) the N-14 Registration
     Statement contained any untrue statement of a material fact or omitted to
     state any material fact relating to Government Mortgage Fund required to
     be stated therein or necessary to make the statements therein not
     misleading; and (2) the Proxy Statement and Prospectus included in the
     N-14 Registration Statement contained any untrue statement of a material
     fact or omitted to state any material fact relating to Government
     Mortgage Fund necessary to make the statements therein, in the light of
     the circumstances under which they were made, not misleading; and (B)
     such counsel does not express any opinion or belief as to the financial
     statements or other financial or statistical data contained or
     incorporated by reference in the N-14 Registration Statement. In giving
     the opinion set forth above, Sidley Austin Brown & Wood LLP may state
     that it is relying on certificates of officers of Government Mortgage
     Fund with regard to matters of fact and certain certificates and



                                     I-14


     written statements of governmental officials with respect to the good
     standing of Government Mortgage Fund.

          (g) That Mercury Fund shall have received an opinion of Sidley
     Austin Brown & Wood LLP to the effect that for Federal income tax
     purposes (i) the transfer by Mercury Fund of substantially all of the
     Mercury Fund Investments to Government Mortgage Fund in exchange solely
     for shares of Government Mortgage Fund as provided in this Agreement will
     constitute a reorganization within the meaning of Section 368(a)(1)(C) of
     the Code and Mercury Fund and Government Mortgage Fund each will be
     deemed to be a "party" to a reorganization within the meaning of Section
     368(b) of the Code; (ii) in accordance with Section 361(a) of the Code,
     no gain or loss will be recognized to Mercury Fund as a result of the
     transfer of its assets solely in exchange for Government Mortgage Fund
     shares or on the distribution of the shares of Government Mortgage Fund
     to its shareholders under Section 361(c)(1) of the Code; (iii) under
     Section 1032 of the Code, no gain or loss will be recognized to
     Government Mortgage Fund on the receipt of assets of Mercury Fund in
     exchange for Government Mortgage Fund shares; (iv) in accordance with
     Section 354(a)(1) of the Code, no gain or loss will be recognized to the
     shareholders of Mercury Fund on the receipt of Corresponding Shares of
     Government Mortgage Fund in exchange for their shares of Mercury Fund;
     (v) in accordance with Section 362(b) of the Code, the tax basis of
     Mercury Fund's assets in the hands of Government Mortgage Fund will be
     the same as the tax basis of such assets in the hands of Mercury Fund
     immediately prior to the consummation of the Reorganization; (vi) in
     accordance with Section 358 of the Code, immediately after the
     Reorganization, the tax basis of the Corresponding Shares of Government
     Mortgage Fund received by the shareholders of Mercury Fund in the
     Reorganization (including fractional shares to which they may be
     entitled) will be equal to the tax basis of the shares of Mercury Fund
     surrendered in exchange; (vii) in accordance with Section 1223 of the
     Code, a stockholder's holding period for the Corresponding Shares of
     Government Mortgage Fund (including fractional shares to which he or she
     may be entitled) will be determined by including the period for which
     such stockholder held Mercury Fund shares exchanged therefor, provided,
     that such shares were held as a capital asset; (viii) in accordance with
     Section 1223 of the Code, Government Mortgage Fund's holding period with
     respect to Mercury Fund's assets transferred will include the period for
     which such assets were held by Mercury Fund; and (ix) the taxable year of
     Mercury Fund will end on the effective date of the Reorganization, and
     pursuant to Section 381(a) of the Code and regulations thereunder,
     Government Mortgage Fund will succeed to and take into account certain
     tax attributes of Mercury Fund, such as earnings and profits, capital
     loss carryovers and method of accounting.

          (h) That all proceedings taken by Government Mortgage Fund and its
     counsel in connection with the Reorganization and all documents
     incidental thereto shall be satisfactory in form and substance to Mercury
     Fund and its counsel.

          (i) That the N-14 Registration Statement shall have become effective
     under the 1933 Act, and no stop order suspending such effectiveness shall
     have been instituted or, to the knowledge of Government Mortgage Fund,
     contemplated by the Commission.



                                     I-15


          (j) That Mercury Fund shall have received from Deloitte & Touche LLP
     a letter dated within three days prior to the effective date of the N-14
     Registration Statement and a similar letter dated within five days prior
     to the Closing Date, in form and substance satisfactory to it, to the
     effect that (i) they are independent public accountants with respect to
     Government Mortgage Fund within the meaning of the 1933 Act and the
     applicable published rules and regulations thereunder; (ii) in their
     opinion, the financial statements and supplementary information of
     Government Mortgage Fund included or incorporated by reference in the
     N-14 Registration Statement and reported on by them comply as to form in
     all material respects with the applicable accounting requirements of the
     1933 Act and the published rules and regulations thereunder; and (iii) on
     the basis of limited procedures agreed upon by Mercury Fund and described
     in such letter (but not an examination in accordance with generally
     accepted auditing standards) consisting of a reading of any unaudited
     interim financial statements and unaudited supplementary information of
     Government Mortgage Fund included in the N-14 Registration Statement, and
     inquiries of certain officials of Government Mortgage Fund responsible
     for financial and accounting matters, nothing came to their attention
     that caused them to believe that (a) such unaudited financial statements
     and related unaudited supplementary information do not comply as to form
     in all material respects with the applicable accounting requirements of
     the 1933 Act and the published rules and regulations thereunder, (b) such
     unaudited financial statements are not fairly presented in conformity
     with generally accepted accounting principles, applied on a basis
     substantially consistent with that of the audited financial statements,
     or (c) such unaudited supplementary information is not fairly stated in
     all material respects in relation to the unaudited financial statements
     taken as a whole; and (iv) on the basis of limited procedures agreed upon
     by Mercury Fund and described in such letter (but not an examination in
     accordance with generally accepted auditing standards), the information
     relating to Government Mortgage Fund appearing in the N-14 Registration
     Statement, which information is expressed in dollars (or percentages
     derived from such dollars) (with the exception of performance
     comparisons, if any), if any, has been obtained from the accounting
     records of Government Mortgage Fund or from schedules prepared by
     officials of Government Mortgage Fund having responsibility for financial
     and reporting matters and such information is in agreement with such
     records, schedules or computations made therefrom.

          (k) That the Commission shall not have issued an unfavorable
     advisory report under Section 25(b) of the 1940 Act, nor instituted or
     threatened to institute any proceeding seeking to enjoin consummation of
     the Reorganization under Section 25(c) of the 1940 Act, and no other
     legal, administrative or other proceeding shall be instituted or
     threatened which would materially affect the financial condition of
     Government Mortgage Fund or would prohibit the Reorganization.

          (l) That Mercury Fund shall have received from the Commission such
     orders or interpretations as Sidley Austin Brown & Wood llp, as counsel
     to Mercury Fund, deems reasonably necessary or desirable under the 1933
     Act and the 1940 Act in connection with the Reorganization, provided that
     such counsel shall have requested such orders as promptly as practicable,
     and all such orders shall be in full force and effect.

     9. Government Mortgage Fund Conditions.

     The obligations of Government Mortgage Fund hereunder with respect to
Mercury Fund shall be subject to the following conditions:

          (a) That this Agreement shall have been adopted, and the
     Reorganization shall have been approved, by (i) the Board of Government
     Mortgage Fund; (ii) the Board of Asset Program; and (iii) by the
     affirmative vote of the holders of a majority of the shares of common
     stock of Mercury Fund issued and outstanding and entitled to vote
     thereon, voting together as a single class; and that Mercury Fund shall
     have delivered to Government Mortgage Fund a copy of the resolution
     approving this Agreement adopted by Mercury Fund's Board, and a
     certificate setting forth the vote that Mercury Fund's shareholders
     obtained, each certified by the Secretary of Mercury Fund.

          (b) That Mercury Fund shall have furnished to Government Mortgage
     Fund a statement of its assets and liabilities, with values determined as
     provided in Section 4 of this Agreement, together with a schedule of
     investments with its respective dates of acquisition and tax costs, all
     as of the Valuation Time, certified on Mercury Fund's behalf by its
     President (or any Vice President) and its Treasurer, and a certificate of
     both such officers, dated the Closing Date, certifying that as of the
     Valuation Time and as of the Closing Date there has been no material
     adverse change in the financial position of Mercury Fund since the date
     of Mercury Fund's most recent Annual or Semi-Annual Report, as
     applicable, other than changes in Mercury Fund Investments since that
     date or changes in the market value of Mercury Fund Investments.

          (c) That Mercury Fund shall have furnished to Government Mortgage
     Fund a certificate signed by its President (or any Vice President) and
     its Treasurer, dated the Closing Date, certifying that as of the
     Valuation Time and as of the Closing Date all representations and
     warranties of Mercury Fund made in this Agreement are true and correct in
     all material respects with the same effect as if made at and as of such
     dates and Mercury Fund has complied with all of the agreements and
     satisfied all of the conditions on its part to be performed or satisfied
     at or prior to such dates.

          (d) That Mercury Fund shall have delivered to Government Mortgage
     Fund a letter from Deloitte & Touche LLP, dated the Closing Date, stating
     that such firm has performed a limited review of the Federal, state and
     local income tax returns of Mercury Fund for the period ended January 31,
     2002 (which returns were prepared and filed by Mercury Fund), and that
     based on such limited review, nothing came to their attention which
     caused them to believe that such returns did not properly reflect, in all
     material respects, the Federal, state and local income taxes of Mercury
     Fund for the period covered thereby; and that for the period from
     February 1, 2002 to and including the Closing Date and for any taxable
     year of Mercury Fund ending upon liquidation, such firm has performed a
     limited review to ascertain the amount of applicable Federal, state and
     local taxes, and has determined that either such amount has been paid or
     reserves established for payment of such taxes, this review to be based
     on unaudited financial data; and that based on such limited review,
     nothing has come to their attention which caused them to believe that the
     taxes paid or reserves set aside for payment of such taxes



                                     I-17


     were not adequate in all material respects for the satisfaction of
     Federal, state and local taxes for the period from February 1, 2002 to
     and including the Closing Date and for any taxable year of Mercury Fund
     ending upon the liquidation or that Mercury Fund would not continue to
     qualify as a regulated investment company for Federal income tax purposes
     for the tax years in question.

          (e) That there shall not be any material litigation pending with
     respect to the matters contemplated by this Agreement.

          (f) That Mercury Fund shall have delivered to Government Mortgage
     Fund an opinion of Sidley Austin Brown & Wood LLP, as counsel to Asset
     Program, in form and substance satisfactory to Government Mortgage Fund
     and dated the Closing Date, to the effect that (i) Asset Program is a
     corporation duly organized, validly existing and in good standing in
     conformity with the laws of the State of Maryland; (ii) this Agreement
     has been duly authorized, executed and delivered by Asset Program, and
     represents a valid and binding contract, enforceable in accordance with
     its terms, except as enforceability may be limited by bankruptcy,
     insolvency, moratorium, fraudulent conveyance and similar laws relating
     to or affecting creditors' rights generally and court decisions with
     respect thereto; provided, such counsel shall express no opinion with
     respect to the application of equitable principles in any proceeding,
     whether at law or in equity; (iii) the execution and delivery of this
     Agreement by Asset Program does not, and the consummation of the
     Reorganization will not, violate any material provisions of Maryland law
     or of the Articles of Incorporation, as amended or supplemented, the
     by-laws, or any agreement (known to such counsel) to which Asset Program
     is a party or by which Mercury Fund is bound, except insofar as the
     parties have agreed to amend any such provision as a condition precedent
     to the Reorganization; (iv) Asset Program has the power to sell, assign,
     transfer and deliver the assets transferred by it hereunder and, upon
     consummation of the Reorganization in accordance with the terms of this
     Agreement, Asset Program will have duly transferred such assets and
     liabilities in accordance with this Agreement; (v) to the best of such
     counsel's knowledge, no consent, approval, authorization or order of any
     United States federal court, Maryland state court or governmental
     authority is required for the consummation by Mercury Fund of the
     Reorganization, except such as have been obtained under the 1933 Act, the
     1934 Act and the 1940 Act and the published rules and regulations of the
     Commission thereunder Maryland law and such as may be required under
     state securities laws; (vi) the N-14 Registration Statement, as of its
     effective date, appears on its face to be appropriately responsive in all
     material respects to the requirements of the 1933 Act, the 1934 Act and
     the 1940 Act and the published rules and regulations of the Commission
     thereunder insofar as it relates to Mercury Fund; (vii) the descriptions
     in the N-14 Registration Statement of statutes, legal and governmental
     proceedings and contracts and other documents insofar as they relate to
     Mercury Fund are accurate and fairly present the information required to
     be shown; (viii) such counsel does not know of any statutes, legal or
     governmental proceedings or contracts or other documents related to the
     Reorganization insofar as they relate to Mercury Fund of a character
     required to be described in the N-14 Registration Statement which are not
     described therein or, if required to be filed, filed as required; (ix)
     Asset Program, to the knowledge of such counsel, is not required to
     qualify to do business as a foreign corporation in any



                                     I-18


     jurisdiction except as may be required by state securities laws, and
     except where it has so qualified or the failure so to qualify would not
     have a material adverse effect on Mercury Fund or its shareholders; (x)
     such counsel does not have actual knowledge of any material suit, action
     or legal or administrative proceeding pending or threatened against Asset
     Program, the unfavorable outcome of which would materially and adversely
     affect Mercury Fund; (xi) all actions required to be taken by Asset
     Program to authorize this Agreement and to effect the Reorganization have
     been duly authorized by all necessary corporate actions; and (xii) such
     opinion is solely for the benefit of Government Mortgage Fund and its
     Board Members and officers. Such opinion also shall state that (a) while
     such counsel cannot make any representation as to the accuracy or
     completeness of statements of fact in the N-14 Registration Statement,
     nothing has come to their attention that has caused them to believe that,
     on the effective date of the N-14 Registration Statement, (1) the N-14
     Registration Statement contained any untrue statement of a material fact
     or omitted to state any material fact relating to Mercury Fund required
     to be stated therein or necessary to make the statements therein not
     misleading; and (2) the Proxy Statement and Prospectus included in the
     N-14 Registration Statement contained any untrue statement of a material
     fact or omitted to state any material fact relating to Mercury Fund
     necessary to make the statements therein, in the light of the
     circumstances under which they were made, not misleading; and (b) such
     counsel does not express any opinion or belief as to the financial
     statements or other financial or statistical data contained or
     incorporated by reference in the N-14 Registration Statement. In giving
     the opinion set forth above, Sidley Austin Brown & Wood LLP may state
     that it is relying on certificates of officers of Asset Program with
     regard to matters of fact and certain certificates and written statements
     of governmental officials with respect to the good standing of Asset
     Program.

          (g) That Government Mortgage Fund shall have received an opinion of
     Sidley Austin Brown & Wood LLP with respect to the matters specified in
     Section 8(g) of this Agreement.

          (h) That Government Mortgage Fund shall have received from Deloitte
     & Touche LLP a letter dated within three days prior to the effective date
     of the N-14 Registration Statement and a similar letter dated within five
     days prior to the Closing Date, in form and substance satisfactory to
     Government Mortgage Fund, to the effect that (i) they are independent
     public accountants with respect to Mercury Fund within the meaning of the
     1933 Act and the applicable published rules and regulations thereunder;
     (ii) in their opinion, the financial statements and supplementary
     information of Mercury Fund included or incorporated by reference in the
     N-14 Registration Statement and reported on by them comply as to form in
     all material respects with the applicable accounting requirements of the
     1933 Act and the published rules and regulations thereunder; (iii) on the
     basis of limited procedures agreed upon by Mercury Fund and Government
     Mortgage Fund and described in such letter (but not an examination in
     accordance with generally accepted auditing standards) consisting of a
     reading of any unaudited interim financial statements and unaudited
     supplementary information of Mercury Fund included in the N-14
     Registration Statement, and inquiries of certain officials of Mercury
     Fund responsible for financial and accounting matters, nothing came to
     their attention that caused them to believe that (a) such unaudited
     financial statements



                                     I-19


     and related unaudited supplementary information do not comply as to form
     in all material respects with the applicable accounting requirements of
     the 1933 Act and the published rules and regulations thereunder, (b) such
     unaudited financial statements are not fairly presented in conformity
     with generally accepted accounting principles, applied on a basis
     substantially consistent with that of the audited financial statements,
     or (c) such unaudited supplementary information is not fairly stated in
     all material respects in relation to the unaudited financial statements
     taken as a whole; and (iv) on the basis of limited procedures agreed upon
     by Government Mortgage Fund and Mercury Fund and described in such letter
     (but not an examination in accordance with generally accepted auditing
     standards), the information relating to Mercury Fund appearing in the
     N-14 Registration Statement, which information is expressed in dollars
     (or percentages derived from such dollars) (with the exception of
     performance comparisons, if any), if any, has been obtained from the
     accounting records of Mercury Fund or from schedules prepared by
     officials of Mercury Fund having responsibility for financial and
     reporting matters and such information is in agreement with such records,
     schedules or computations made therefrom.

          (i) That the N-14 Registration Statement shall have become effective
     under the 1933 Act and no stop order suspending such effectiveness shall
     have been instituted or, to the knowledge of Mercury Fund, contemplated
     by the Commission.

          (j) That the Commission shall not have issued an unfavorable
     advisory report under Section 25(b) of the 1940 Act, nor instituted or
     threatened to institute any proceeding seeking to enjoin consummation of
     the Reorganization under Section 25(c) of the 1940 Act, and no other
     legal, administrative or other proceeding shall be instituted or
     threatened which would materially affect the financial condition of
     Mercury Fund or would prohibit the Reorganization.

          (k) That Government Mortgage Fund shall have received from the
     Commission such orders or interpretations as Sidley Austin Brown & Wood
     LLP, as counsel to Government Mortgage Fund, deems reasonably necessary
     or desirable under the 1933 Act and the 1940 Act in connection with the
     Reorganization, provided, that such counsel shall have requested such
     orders as promptly as practicable, and all such orders shall be in full
     force and effect.

          (l) That all proceedings taken by Mercury Fund and its counsel in
     connection with the Reorganization and all documents incidental thereto
     shall be satisfactory in form and substance to Government Mortgage Fund.

          (m) That prior to the Closing Date, Mercury Fund shall have declared
     a dividend or dividends which, together with all such previous dividends,
     shall have the effect of distributing to its shareholders all of its
     investment company taxable income for the period to and including the
     Closing Date, if any (computed without regard to any deduction for
     dividends paid), and all of its net capital gain, if any, realized to and
     including the Closing Date.



                                     I-20


     10. Termination, Postponement and Waivers.

          (a) Notwithstanding anything contained in this Agreement to the
     contrary, this Agreement may be terminated and the Reorganization
     abandoned at any time (whether before or after adoption thereof by the
     shareholders of Mercury Fund) prior to the Closing Date, or the Closing
     Date may be postponed, (i) by mutual consent of the Boards of Government
     Mortgage Fund and Mercury Fund; (ii) by the Board of Mercury Fund if any
     condition of Mercury Fund's obligations set forth in Section 8 of this
     Agreement has not been fulfilled or waived by such Board; or (iii) by the
     Board of Government Mortgage Fund if any condition of Government Mortgage
     Fund's obligations with respect to the Reorganization set forth in
     Section 9 of this Agreement has not been fulfilled or waived by such
     Board.

          (b) If the transactions contemplated by this Agreement with respect
     to the Reorganization have not been consummated by March 31, 2003, this
     Agreement automatically shall terminate on that date unless a later date
     is mutually agreed to by the Boards of Government Mortgage Fund and
     Mercury Fund.

          (c) In the event of termination of this Agreement pursuant to the
     provisions hereof with respect to the Reorganization, the same shall
     become void and have no further effect, and there shall not be any
     liability on the part of Government Mortgage Fund and Mercury Fund or
     persons who are their directors, trustees, officers, agents or
     shareholders in respect of this Agreement.

          (d) At any time prior to the Closing Date, any of the terms or
     conditions of this Agreement may be waived by the Board of either Fund
     (whichever is entitled to the benefit thereof), if, in the judgment of
     such Board after consultation with its counsel, such action or waiver
     will not have a material adverse effect on the benefits intended under
     this Agreement to the shareholders of the Fund, on behalf of which such
     action is taken. In addition, the Board of each Fund has delegated to FAM
     the ability to make non-material changes to the transaction if FAM deems
     it to be in the best interests of that Fund to do so.

          (e) The respective representations and warranties contained in
     Sections 1 and 2 of this Agreement relating to Government Mortgage Fund
     and Mercury Fund shall expire with, and be terminated by, the
     consummation of the Reorganization, and neither Government Mortgage Fund
     nor Mercury Fund nor any of their officers, directors or trustees, agents
     or shareholders shall have any liability with respect to such
     representations or warranties after the Closing Date. This provision
     shall not protect any officer, director or trustee, agent or shareholder
     of any Fund against any liability to the entity for which that officer,
     director or trustee, agent or shareholder so acts or to its shareholders,
     to which that officer, director or trustee, agent or shareholder
     otherwise would be subject by reason of willful misfeasance, bad faith,
     gross negligence, or reckless disregard of the duties in the conduct of
     such office.

          (f) If any order or orders of the Commission with respect to this
     Agreement relating to the Reorganization shall be issued prior to the
     Closing Date and shall impose



                                     I-21


     any terms or conditions which are determined by action of the Boards of
     Government Mortgage Fund and Mercury Fund to be acceptable, such terms
     and conditions shall be binding as if a part of this Agreement without
     further vote or approval of the shareholders of Mercury Fund unless such
     terms and conditions shall result in a change in the method of computing
     the number of shares of Government Mortgage Fund to be issued to Mercury
     Fund in which event, unless such terms and conditions shall have been
     included in the proxy solicitation materials furnished to the
     shareholders of Mercury Fund prior to the meeting at which the
     Reorganization shall have been approved, this Agreement shall not be
     consummated and shall terminate unless Mercury Fund promptly shall call a
     special meeting of shareholders at which such conditions so imposed shall
     be submitted for approval.

     11. Other Matters.

          (a) Pursuant to Rule 145 under the 1933 Act, and in connection with
     the issuance of any shares to any person who at the time of the
     Reorganization is, to its knowledge, an affiliate of a party to the
     Reorganization pursuant to Rule 145(c), Government Mortgage Fund will
     cause to be affixed upon the certificate(s) issued to such person (if
     any) a legend as follows:

              THESE SHARES ARE SUBJECT TO RESTRICTIONS ON TRANSFER UNDER THE
          SECURITIES ACT OF 1933 AND MAY NOT BE SOLD OR OTHERWISE TRANSFERRED

         STATUTORY SUCCESSOR) (THE "FUND") OR ITS PRINCIPAL UNDERWRITER UNLESS
         (1) A REGISTRATION STATEMENT WITH RESPECT THERETO IS EFFECTIVE
         UNDER THE SECURITIES ACT OF 1933 OR (2) IN THE OPINION OF COUNSEL
         REASONABLY SATISFACTORY TO THE FUND, SUCH REGISTRATION IS NOT
         REQUIRED.

     and, further, that stop transfer instructions will be issued to Government
     Mortgage Fund's transfer agent with respect to such shares. Mercury Fund
     will provide Government Mortgage Fund on the Closing Date with the name of
     any stockholder who is to the knowledge of Mercury Fund an affiliate of
     Mercury Fund on such date.

          (b) All covenants, agreements, representations and warranties made
     under this Agreement and any certificates delivered pursuant to this
     Agreement shall be deemed to have been material and relied upon by each
     of the parties, notwithstanding any investigation made by them or on
     their behalf.

          (c) Any notice, report or demand required or permitted by any
     provision of this Agreement shall be in writing and shall be made by hand

                                     I-22


          (d) This Agreement supersedes all previous correspondence and oral
     communications between the parties regarding the Reorganization,
     constitutes the only understanding with respect to the Reorganization,
     except as provided in Section 10(d) may not be changed other than by a

     New York applicable to agreements made and to be performed in said state.

          (e) Copies of the Articles of Incorporation, as amended and
     supplemented, of Asset Program are on file with the State Department of

     given that this instrument is executed on behalf of the Board Members of
     Asset Program.

          (f) It is expressly agreed that the obligations of Government
     Mortgage Fund hereunder shall not be binding upon any of its Board
     Members, shareholders, nominees, officers, agents, or employees
     personally, but shall bind only the trust property of Government Mortgage
     Fund as provided in such Fund's Declaration of Trust. The execution and
     delivery of this Agreement has been authorized by the Board of Government
     Mortgage Fund and signed by authorized officers of Government Mortgage
     Fund, acting as such, and neither such authorization by such Board
     Members, nor such execution and delivery by such officers shall be deemed
     to have been made by any of them individually or to impose any liability
     on any of them personally, but shall bind only the trust property of
     Government Mortgage Fund as provided in such Fund's Declaration of Trust.



                                     I-23


     This Agreement may be executed in any number of counterparts, each of

                                    PART C

                               OTHER INFORMATION

Item 15.  Indemnification.

     Section 5.3 of the Declaration of Trust of Merrill Lynch U.S. Government
Mortgage Fund (the "Registrant") provides as follows:

     "The Trust shall indemnify each of its Trustees, officers, employees, and
agents (including persons who serve at its request as directors, officers or
trustees of another organization in which it has any interest as a
shareholder, creditor or otherwise) against all liabilities and expenses
(including amounts paid in satisfaction of judgments, in compromise, as fines
and penalties, and as counsel fees) reasonably incurred by him in connection
with the defense or disposition of any action, suit or other proceeding,
whether civil or criminal, in which he may be involved or with which he may be
threatened, while in office or thereafter, by reason of his being or having
been such a trustee, officer, employee or agent, except with respect to any
matter as to which he shall have been adjudicated to have acted in bad faith,
willfull misfeasance, gross negligence or reckless disregard of his duties;
provided, however, that as to any matter disposed of by a compromise payment
by such person, pursuant to a consent decree or otherwise, no indemnification
either for said payment or for any other expenses shall be provided unless the
Trust shall have received a written opinion from independent legal counsel
approved by the Trustees to the effect that if either the matter of willful
misfeasance, gross negligence or reckless disregard of duty, or the matter of
good faith and reasonable belief as to the best interests of the Trust, had
been adjudicated, it would have been adjudicated in favor of such person. The
rights accruing to any Person under these provisions shall not exclude any
other right to which he may be lawfully entitled; provided that no Person may
satisfy any right of indemnity or reimbursement granted herein or in Section
5.1 or to which he may be otherwise entitled except out of the property of the
Trust, and no shareholder shall be personally liable to any Person with
respect to any claim for indemnity or reimbursement or otherwise. The Trustees
may make advance payments in connection with indemnification under this
Section 5.3, provided that the indemnified person shall have given a written
undertaking to reimburse the Trust in the event it is subsequently determined
that he is not entitled to such indemnification."

     Insofar as the conditional advancing of indemnification moneys for
actions based upon the Investment Company Act of 1940 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 to 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.

     Insofar as indemnification for liabilities arising under the Securities
Act of 1933, as amended (the "1933 Act") 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 1933 Act and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a 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.

Merrill Lynch U.S. Government Mortgage Fund
800 Scudders Mill Road
Plainsboro, New Jersey  08536

Ladies and Gentlemen:

     We have acted as counsel for Merrill Lynch U.S. Government Mortgage Fund
(the "Fund"), in connection with the proposed acquisition by the Fund of
substantially all of the assets and the assumption by the Fund of
substantially all of the liabilities of Mercury U.S. Government Securities
Fund ("Mercury Fund"), a series of The Asset Program, Inc. ("Asset Program"),
and the simultaneous distribution to Mercury Fund of newly-issued shares of
beneficial interest of the Fund, having an aggregate net asset value equal to
the aggregate net asset value of Mercury Fund, reduced by the amount of
liabilities of Mercury Fund assumed by the Fund (collectively the
"Reorganization"). This opinion is furnished in connection with the Fund's
Registration Statement on Form N-14 under the Securities Act of 1933, as
amended (the "Registration Statement"), relating to shares of beneficial
interest, par value $0.10 per share, of the Fund (the "Shares") to be issued
in the Reorganization.

     As counsel for the Fund, we are familiar with the proceedings taken by it
and to be 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 Fund, as amended, the By-Laws of the Fund, as
amended, 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 subsequent to the
approval of the Agreement and Plan of Reorganization between the Fund and
Asset Program set forth in the joint proxy statement and prospectus
constituting a part of the Registration Statement (the "Proxy Statement and
Prospectus"), the Shares, upon issuance 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 shares of beneficial
interest of the Fund, except that shareholders of the Fund may under certain
circumstances be held personally liable for the Fund's obligations as
described in the Registration Statement under the caption "Comparison of the
Funds - Limitation of Liability."


     This opinion letter is rendered solely to and for the benefit of the Fund
in connection with the matter described above; accordingly, it may not be
quoted or otherwise delivered to or relied upon by any other person (including,
without limitation, any person who acquires the Shares from the Fund) or used
