THE FUND

[ICON]  INVESTMENT OBJECTIVES
- --------------------------------------------------------------------------------

           Morgan Stanley Dean Witter U.S. Government Money Market Trust (the
           "Fund") is a money market fund that seeks to provide security of
           principal, high current income and liquidity.


[ICON]  PRINCIPAL INVESTMENT STRATEGIES
- --------------------------------------------------------------------------------
             The Fund will invest in high quality, short-term U.S. Government
             securities. The Fund's "Investment Manager," Morgan Stanley Dean
             Witter Advisors Inc., seeks to maintain the Fund's share price at
             $1.00. The share price remaining stable at $1.00 means that the
             Fund would preserve the principal value of your investment.
             The U.S. Government securities that the Fund may purchase include:
                            - U.S. Treasury bills, notes and bonds, all of which
                              are direct obligations of the U.S. Government.
                            - Securities issued by agencies and
                              instrumentalities of the U.S. Government which are
                              backed by the full faith and credit of the United
                              States. Among the agencies and instrumentalities
                              issuing these obligations are the Government
                              National Mortgage Association and the Federal
                              Housing Administration.

                            - Securities issued by agencies and
                              instrumentalities which are not backed by the full
                              faith and credit of the United States, but whose
                              issuing agency or instrumentality has the right to
                              borrow, to meet its obligations, from the U.S.
                              Treasury. Among these agencies and
                              instrumentalities are the Federal National
                              Mortgage Association, the Federal Home Loan
                              Mortgage Corporation and the Federal Home Loan
                              Banks.

                            - Securities issued by agencies and
                              instrumentalities which are backed solely by the
                              credit of the issuing agency or instrumentality.
                              Among these agencies and instrumentalities is the
                              Federal Farm Credit System.

             The Fund also may invest up to 10% of its assets in FDIC insured
             certificates of deposit of banks and saving and loan institutions.
             The Fund's policies discussed above are fundamental. These policies
             may not be changed without shareholder approval. In addition to the
             fundamental investment policies, the Fund may invest in repurchase
             agreements. Repurchase agreements are contracts in which a
             financial institution sells a security and agrees to buy it back on
             a specific date (usually within 7 days) and at a higher price,
             which reflects an agreed-upon interest rate.

                                                                               1

[ICON]  PRINCIPAL RISKS
- --------------------------------------------------------------------------------

             There is no assurance that the Fund will achieve its investment
             objectives.


            CREDIT AND INTEREST RATE RISKS. A principal risk of investing in the
             Fund is associated with its U.S. Government securities investments,
             which are subject to two types of risks: credit risk and interest
             rate risk. Credit risk refers to the possibility that the issuer of
             a security will be unable to make interest payments and repay the
             principal on its debt. Interest rate risk, another risk of debt
             securities, refers to fluctuations in the value of a fixed-income
             security resulting from changes in the general level of interest
             rates.

             Credit risk is minimal with respect to the Fund's U.S. Government
             securities investments. Repurchase agreements involve a greater
             degree of credit risk. The Investment Manager, however, actively
             manages the Fund's assets to reduce the risk of losing any
             principal investment as a result of credit or interest rate risks.
             In addition, federal regulations require money market funds, such
             as the Fund, to invest only in debt obligations of high quality and
             short maturities.


             Shares of the Fund are not bank deposits and are not insured or
             guaranteed by the FDIC or any other government agency. Although the
             Fund seeks to preserve the value of your investment at $1.00 per
             share, if it is unable to do so, it is possible to lose money by
             investing in the Fund.

           EXAMPLE
           This example is intended to help you compare the cost of investing in
           the Fund with the cost of investing in other mutual funds.

           The example assumes that you invest $10,000 in the Fund, your
           investment has a 5% return each year, and the Fund's operating
           expenses remain the same. Although your actual costs may be higher or
           lower, the table below shows your costs at the end of each period
           based on these assumptions.

[ICON]  FUND MANAGEMENT
- --------------------------------------------------------------------------------
             The Fund has retained the Investment Manager -- Morgan Stanley Dean
             Witter Advisors Inc. -- to provide administrative services, manage
             its business affairs and invest its assets, including the placing
             of orders for the purchase and sale of portfolio securities. The
             Investment Manager is a wholly-owned subsidiary of Morgan Stanley
             Dean Witter & Co., a preeminent global financial services firm that
             maintains leading market positions in each of its three primary

SHAREHOLDER INFORMATION

[ICON]  PRICING FUND SHARES
- --------------------------------------------------------------------------------
           The price of Fund shares, called "net asset value," is based on the
           amortized cost of the Fund's portfolio securities. The amortized cost
           valuation method involves valuing a debt obligation in reference to
           its cost, rather than market forces.

           The net asset value per share of the Fund is determined once daily at
           4:00 p.m. Eastern time on each day that the New York Stock Exchange
           is open (or, on days when the New York Stock Exchange closes prior to
           4:00 p.m., at such earlier time). Shares will not be priced on days
           that the New York Stock Exchange is closed.

[ICON]  HOW TO BUY SHARES

             You may open a new account to buy Fund shares or buy additional
             Fund shares for an existing account in several ways. When you buy
             Fund shares, the shares are purchased at the next share price
             calculated after we receive your purchase order accompanied by
             federal or other immediately available funds. You begin earning
             dividends the business day after the shares are purchased. We
             reserve the right to reject any order for the purchase of Fund
             shares.

            ADDITIONAL PURCHASE INFORMATION. If you are a customer of Dean
             Witter Reynolds or another authorized dealer of Fund shares, you
             may upon request: (a) have the proceeds from the sale of listed
             securities invested in Fund shares the day after you receive the
             proceeds; and (b) pay for the purchase of certain listed securities
             by automatic sale of Fund shares that you own. If you are a
             customer of Dean Witter Reynolds or another authorized dealer of
             the Fund's shares, you may have cash balances in your securities
             account of $1,000 or more automatically invested in shares of the
             Fund on the next business day after the balance is accrued in your
             account. Cash balances of less than $1,000 may be automatically
             invested in Fund shares on a weekly basis.


            PLAN OF DISTRIBUTION. The Fund has adopted a Plan of Distribution in
             accordance with Rule 12b-1 under the Investment Company Act of
             1940. The Plan allows the Fund to pay distribution fees of up to
             0.15% of its average daily net assets for the sale and distribution
             of Fund shares. It also allows the Fund to pay for services to
             shareholders. Because these fees are paid out of the Fund's assets
             on an ongoing basis, over time these fees will increase the cost of
             your investment and may cost you more than paying other types of
             sales charges.


[ICON]  HOW TO EXCHANGE SHARES
- --------------------------------------------------------------------------------

            PERMISSIBLE FUND EXCHANGES. You may only exchange shares of the Fund
             for shares of other continuously offered Morgan Stanley Dean Witter
             Funds if the Fund shares were acquired in an exchange of shares
             initially purchased in a Multi-Class Fund or an FSC Fund (subject
             to a front-end sales charge). In that case, the shares may be
             subsequently re-exchanged for shares of the same Class of any
             Multi-Class Fund or FSC Fund or for shares of another Money Market
             Fund, a No-Load Fund, North American Government Income Trust, or
             Short-Term U.S. Treasury Trust. Of course, if an exchange is not
             permitted, you may sell shares of the Fund and buy another fund's
             shares with the proceeds.



             See the inside back cover of this PROSPECTUS for each Morgan
             Stanley Dean Witter Fund's designation as a Multi-Class Fund, FSC
             Fund, No-Load Fund or Money Market Fund. If a Morgan Stanley Dean
             Witter Fund is not listed, consult the inside back cover of that
             fund's prospectus for its designation. For purposes of exchanges,
             shares of FSC Funds are treated as Class A shares of a Multi-Class
             Fund.


                                                                               7
<PAGE>

           The current prospectus for each fund describes its investment
           objective(s), policies and investment minimums, and should be read
           before investing.

           EXCHANGE PROCEDURES. You can process an exchange by contacting your
           Morgan Stanley Dean Witter Financial Advisor or other authorized
           financial representative. Otherwise, you must forward an exchange
           privilege authorization form to the Fund's transfer agent -- Morgan
           Stanley Dean Witter Trust FSB -- and then write the transfer agent or
           call (800) 869-NEWS to place an exchange order. You can obtain an
           exchange privilege authorization form by contacting your Financial
           Advisor or other authorized financial representative or by calling
           (800) 869-NEWS.
           An exchange to any Morgan Stanley Dean Witter Fund (except a Money
           Market Fund) is made on the basis of the next calculated net asset
           values of the Funds involved after the exchange instructions are
           accepted. When exchanging into a Money Market Fund, the Fund's shares
           are sold at their next calculated net asset value and the Money
           Market Fund's shares are purchased at their net asset value on the
           following business day.

             The Fund may terminate or revise the exchange privilege upon
             required notice. The check writing privilege is not available for
             Money Market Fund shares you acquire in an exchange.

            TELEPHONE EXCHANGES. For your protection when calling Morgan Stanley
             Dean Witter Trust FSB, we will employ reasonable procedures to
             confirm that exchange instructions communicated over the telephone
             are genuine. These procedures may include requiring various forms
             of personal identification such as name, mailing address, social
             security or other tax identification number. Telephone instructions
             also may be recorded.

             Telephone instructions will be accepted if received by the Fund's
             transfer agent between 9:00 a.m. and 4:00 p.m. Eastern time on any
             day the New York Stock Exchange is open for business. During
             periods of drastic economic or market changes, it is possible that
             the telephone exchange procedures may be difficult to implement,
             although this has not been the case with the Fund in the past.

            MARGIN ACCOUNTS. If you have pledged your Fund shares in a margin
             account, contact your Morgan Stanley Dean Witter Financial Advisor
             or other authorized financial representative regarding restrictions
             on the exchange of such shares.
            EXCHANGING SHARES OF ANOTHER FUND SUBJECT TO A CONTINGENT DEFERRED
            SALES CHARGE ("CDSC"). There are special considerations when you
             exchange shares subject to a CDSC of another Morgan Stanley Dean
             Witter Fund for shares of the Fund. When determining the length of
             time you held the shares and the corresponding CDSC rate, any
             period (starting at the end of the month) during which you held
             shares of the Fund WILL NOT BE COUNTED. Thus, in effect the
             "holding period" for purposes of calculating the CDSC is frozen
             upon exchanging into the Fund. Nevertheless, if shares subject to a
             CDSC are exchanged for shares of the Fund, you will receive a
             credit when you sell the

                                    sales of shares, not Fund "distributions," and ultimately
                                    may exhaust your account balance. The Fund may terminate or

                                    Plan, the shares may be subject to a contingent deferred
                                    sales charge ("CDSC") if they were obtained in exchange for
                                    shares subject to a CDSC of another Morgan Stanley Dean
                                    Witter Fund. The CDSC, however, will be waived in an amount
                                    up to 12% annually of the Fund's value, although Fund shares
                                    with no CDSC will be sold first, followed by those with the
                                    lowest CDSC. As such, the waiver benefit will be reduced by
                                    the amount of your shares that are not subject to a CDSC.
                                    See the prospectus of the Fund that charges the CDSC for

             Payment may be postponed or the right to sell your shares
             suspended, however, under unusual circumstances. If you request to
             sell shares that were recently purchased by check, your sale will
             not be effected until it has been verified that the check has been
             honored.

            INVOLUNTARY SALES. The Fund reserves the right, on sixty days'
             notice, to sell the shares of any shareholder whose shares, due to
             sales by the shareholder, have a value below $500. However, before
             the Fund sells your shares in this manner, we will notify you and
             allow you sixty days to make an additional investment in an amount
             that will increase the value of your account to at least the
             required amount before the sale is processed.

             brokerage account with Dean Witter Reynolds or another authorized
             dealer of Fund shares, you may elect to have your Fund shares
             automatically sold from your account to satisfy amounts you owe as
             a result of purchasing securities or other transactions in your
             brokerage account.
             If you elect to participate by notifying Dean Witter Reynolds or
             another authorized dealer of Fund shares, your brokerage account
             will be scanned each business day prior to the close of business
             (4:00 p.m. Eastern time). After any cash balances in the account
             are applied, a sufficient number of Fund shares may be sold to
             satisfy any amounts you are obligated to pay to Dean Witter
             Reynolds or another authorized dealer of fund shares.
             Sales will be effected on the business day before the date you are
             obligated to make payment, and Dean Witter Reynolds or another
             authorized dealer of Fund shares will receive the sale proceeds on
             the following day.

             sufficient number of shares of the Fund be automatically sold and
             the proceeds transferred to Morgan Stanley Dean Witter Trust FSB,
             on a semi-monthly, monthly or quarterly basis, for investment in
             shares of the specified fund. Sales of your Fund shares will be
             made on the business day preceding the investment date and Morgan

             investment on the day following the sale date.

[ICON]  DISTRIBUTIONS
- --------------------------------------------------------------------------------
           The Fund passes substantially all of its earnings along to its
           investors as "distributions." The Fund earns interest from
           fixed-income investments. These amounts are passed along to Fund
           shareholders as "income dividend distributions." The Fund may realize
           capital gains whenever it sells securities for a higher price than it
           paid for them. These amounts may be passed along as "capital gain
           distributions;" the Investment Manager does not anticipate that there
           will be significant capital gain distributions.

                            The Fund declares income dividends payable on each
                            day the New York Stock Exchange is open for
                            business. Capital gains, if any, are distributed
                            periodically.

                            Distributions are reinvested automatically in
                            additional shares of the Fund (rounded to the last
                            1/100 of a share) and automatically credited to your
                            account unless you request in writing that
                            distributions be paid in cash. If you elect the cash
                            option, the Fund will reinvest the additional shares
                            and credit your account during the month, then
                            redeem the credited amount no later than the last
                            business day of the month, and mail a check to you
                            no later than seven business days after the end of
                            the month. No interest will accrue on uncashed
           checks. If you wish to change how your distributions are paid, your
           request should be received by the Fund's transfer agent, Morgan
           Stanley Dean Witter Trust FSB, at least five business days prior to
           the record date of the distributions.

[ICON]  TAX CONSEQUENCES
- --------------------------------------------------------------------------------
           As with any investment, you should consider how your Fund investment
           will be taxed. The tax information in this PROSPECTUS is provided as
           general information. You should consult your own tax professional
           about the tax consequences of an investment in the Fund.
           Unless your investment in the Fund is through a tax-deferred
           retirement account, such as a 401(k) plan or IRA, you need to be
           aware of the possible tax consequences when the Fund makes
           distributions.
           Your distributions are normally subject to federal and state income
           tax when they are paid, whether you take them in cash or reinvest
           them in Fund shares. A distribution also may be subject to local
           income tax. Any income dividend distributions and any short-term
           capital gain distributions are taxable to you as ordinary income. Any
           long-term capital gain distributions are taxable as long-term capital
           gains, no matter how long you have owned shares in the Fund.

           Every January, you will be sent a statement (IRS Form 1099-DIV)
           showing the taxable distributions paid to you in the previous year.
           The statement provides information on your dividends and capital
           gains for tax purposes.

<PAGE>
           When you open your Fund account, you should provide your social
           security or tax identification number on your investment application.
           By providing this information, you will avoid being subject to a
           federal backup withholding tax of 31% on taxable distributions and
           sale proceeds. Any withheld amount would be sent to the IRS as an
           advance tax payment.

                                                                              13

FINANCIAL HIGHLIGHTS


The financial highlights table is intended to help you understand the Fund's
financial performance for the past 5 fiscal years of the Fund. Certain
information reflects financial results for a single Fund share throughout each
year. The total returns in the table represent the rate an investor would have
earned or lost on an investment in the Fund (assuming reinvestment of all
dividends and distributions).



This information has been audited by PricewaterhouseCoopers LLP, independent
accountants, whose report, along with the Fund's financial statements, is
included in this PROSPECTUS.

NOTES TO FINANCIAL STATEMENTS JANUARY 31, 2000



1. ORGANIZATION AND ACCOUNTING POLICIES



Morgan Stanley Dean Witter U.S. Government Money Market Trust (the "Fund"), is
registered under the Investment Company Act of 1940, as amended (the "Act"), as
a diversified, open-end management investment company. The Fund's investment
objectives are security of principal, high current income and liquidity. The
Fund was organized as a Massachusetts business trust on November 18, 1981 and
commenced operations on February 17, 1982.



The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts and disclosures. Actual results could differ from
those estimates.



The following is a summary of significant accounting policies:



A. VALUATION OF INVESTMENTS -- Portfolio securities are valued at amortized
cost, which approximates market value.



B. ACCOUNTING FOR INVESTMENTS -- Security transactions are accounted for on the

MORGAN STANLEY DEAN WITTER U.S. GOVERNMENT MONEY MARKET TRUST
REPORT OF INDEPENDENT ACCOUNTANTS

TO THE SHAREHOLDERS AND TRUSTEES
OF MORGAN STANLEY DEAN WITTER U.S. GOVERNMENT MONEY MARKET TRUST


In our opinion, the accompanying statement of assets and liabilities, including
the portfolio of investments, and the related statements of operations and of
changes in net assets and the financial highlights (appearing in the "Financial
Highlights" table on page 14 of this Prospectus) present fairly, in all material
respects, the financial position of Morgan Stanley Dean Witter U.S. Government
Money Market Trust (the "Fund") at January 31, 2000, the results of its
operations for the year then ended, the changes in its net assets for each of
the two years in the period then ended and the financial highlights for each of
the five years in the period then ended, in conformity with accounting
principles generally accepted in the United States. These financial statements
and financial highlights (hereafter referred to as "financial statements") are
the responsibility of the Fund's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with auditing standards
generally accepted in the United States, which require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits, which included confirmation of securities at
January 31, 2000 by correspondence with the custodian, provide a reasonable
basis for the opinion expressed above.

II. DESCRIPTION OF THE FUND AND ITS INVESTMENTS AND RISKS
- --------------------------------------------------------------------------------

A. CLASSIFICATION

    The Fund is an open-end, diversified management investment company whose
investment objectives are security of principal, high current income and
liquidity.

B. INVESTMENT STRATEGIES AND RISKS

    The following discussion of the Fund's investment strategies and risks
should be read with the sections of the Fund's PROSPECTUS titled "Principal
Investment Strategies" and "Principal Risks."

    REPURCHASE AGREEMENTS.  The Fund may invest in repurchase agreements. When
cash may be available for only a few days, it may be invested by the Fund in
repurchase agreements until such time as it may otherwise be invested or used
for payments of obligations of the Fund. These agreements, which may be viewed
as a type of secured lending by the Fund, typically involve the acquisition by
the Fund of debt securities from a selling financial institution such as a bank,
savings and loan association or broker-dealer. The agreement provides that the
Fund will sell back to the institution, and that the institution will
repurchase, the underlying security serving as collateral at a specified price
and at a fixed time in the future, usually not more than seven days from the
date of purchase. The Fund will accrue interest from the institution until the
time when the repurchase is to occur. Although this date is deemed by the Fund
to be the maturity date of a repurchase agreement, the maturities of securities
subject to repurchase agreements are not subject to any limits.


    While repurchase agreements involve certain risks not associated with direct
investments in debt securities, the Fund follows procedures designed to minimize
such risks. These procedures include effecting repurchase transactions only with
large, well-capitalized and well-established financial institutions, whose
financial condition will be continuously monitored. In addition, the value of
the collateral underlying the repurchase agreement will always be at least equal
to the resale price which consists of the acquisition price paid to the seller
of the securities plus the accrued resale premium which is defined as the amount
specified in the repurchase agreement or the daily amortization of the
difference between the acquisition price and the resale price specified in the
repurchase agreement. Such collateral will consist entirely of securities that
are direct obligations of, or that are fully guaranteed as to principal and
interest by, the United States or any agency thereof, and/or certificates of
deposit, bankers' acceptances which are eligible for acceptance by a Federal
Reserve Bank, and, if the seller is a bank, mortgage related securities (as such
term is defined in section 3(a)(41) of the Securities Exchange Act of 1934 that,
at the time the repurchase agreement is entered into, are rated in the highest
rating category by the Requisite NRSROs (as defined under Rule 2a-7 of the
Investment Company Act of 1940). Additionally, Upon an Event of Insolvency (as
defined under Rule 2a-7) with respect to the seller, the collateral must qualify
the repurchase agreement for preferential treatment under a provision of
applicable insolvency law providing an exclusion from any automatic stay of
creditors' rights against the seller. In the event of a default or bankruptcy by
a selling financial institution, the Fund will seek to liquidate such
collateral. However, the exercising of the Fund's right to liquidate such
collateral could involve certain costs or delays and, to the extent that
proceeds from any sale upon a default of the obligation to repurchase were less
than the repurchase price, the Fund could suffer a loss. It is the current
policy of the Fund not to invest in repurchase agreements that do not mature
within seven days if any such investment, together with any other illiquid
assets held by the Fund, amount to more than 10% of its total assets. The Fund's
investments in repurchase agreements may at times be substantial when, in the
view of the Fund's investment manager, liquidity or other considerations
warrant.


                                       4
<PAGE>
    REVERSE REPURCHASE AGREEMENTS.  The Fund may also use reverse repurchase
agreements as part of its investment strategy. Reverse repurchase agreements
involve sales by the Fund of portfolio assets concurrently with an agreement by
the Fund to repurchase the same assets at a later date at a fixed price.
Generally, the effect of such a transaction is that the Fund can recover all or
most of the cash invested in the portfolio securities involved during the term
of the reverse repurchase agreement, while it will be able to keep the interest
income associated with those portfolio securities. Such transactions are only
advantageous if the interest cost to the Fund of the reverse repurchase
transaction is less than the cost of obtaining the cash otherwise. Opportunities
to achieve this advantage may not always be available, and the Fund intends to
use the reverse repurchase technique only when it will be to its advantage to do
so. The Fund will establish a segregated account with its custodian bank in
which it will maintain cash or cash equivalents or other portfolio securities
equal in value to its obligations in respect of reverse repurchase agreements.
Reverse repurchase agreements are considered borrowings by the Fund and for
purposes other than meeting redemptions may not exceed 5% of the Fund's total
assets.

    LENDING PORTFOLIO SECURITIES.  The Fund may lend its portfolio securities to
brokers, dealers and other financial institutions, provided that the loans are
callable at any time by the Fund, and are at all times secured by cash or cash
equivalents, which are maintained in a segregated account pursuant to applicable
regulations and that are equal to at least 100% of the market value, determined
daily, of the loaned securities. The advantage of these loans is that the Fund
continues to receive the income on the loaned securities while at the same time
earning interest on the cash amounts deposited as collateral, which will be
invested in short-term obligations. The Fund will not lend its portfolio
securities if such loans are not permitted by the laws or regulations of any
state in which its shares are qualified for sale and will not lend more than 10%
of the value of its total assets.

    As with any extensions of credit, there are risks of delay in recovery and,
in some cases, even loss of rights in the collateral should the borrower of the
securities fail financially. However, these loans of portfolio securities will
only be made to firms deemed by the Fund's management to be creditworthy and
when the income which can be earned from such loans justifies the attendant
risks. Upon termination of the loan, the borrower is required to return the
securities to the Fund. Any gain or loss in the market price during the loan
period would inure to the Fund.

    When voting or consent rights which accompany loaned securities pass to the
borrower, the Fund will follow the policy of calling the loaned securities, to
be delivered within one day after notice, to permit the exercise of the rights
if the matters involved would have a material effect on the Fund's investment in
the loaned securities. The Fund will pay reasonable finder's, administrative and
custodial fees in connection with a loan of its securities.

    WHEN-ISSUED AND DELAYED DELIVERY SECURITIES.  From time to time the Fund may
purchase securities on a when-issued or delayed delivery basis. When these
transactions are negotiated, the price is fixed at the time of the commitment,
but delivery and payment can take place a month or more after the date of
commitment. While the Fund will only purchase securities on a when-issued,
delayed delivery with the intention of acquiring the securities, the Fund may
sell the securities before the settlement date, if it is deemed advisable. The
securities so purchased or sold are subject to market fluctuation and no
interest or dividends accrue to the purchaser prior to the settlement date.

    At the time the Fund makes the commitment to purchase or sell securities on
a when-issued, delayed delivery, it will record the transaction and thereafter
reflect the value, each day, of such security purchased, or if a sale, the
proceeds to be received, in determining its net asset value. At the time of
delivery of the securities, their value may be more or less than the purchase or
sale price. An increase in the percentage of the Fund's assets committed to the
purchase of securities on a when-issued, delayed delivery may increase the
volatility of its net asset value. The Fund will also establish a segregated
account on the Fund's books in which it will continually maintain cash or cash
equivalents or other liquid portfolio securities equal in value to commitments
to purchase securities on a when-issued or delayed delivery basis.


    YEAR 2000.  The investment management services provided to the Fund by the
Investment Manager and the services provided to shareholders by the Distributor
and the Transfer Agent depend on the smooth functioning of their computer
systems. Many computer software systems in use today were


                                       5
<PAGE>

designed in such a way that they may not be able to recognize the year 2000, but
revert to 1900 or some other date, due to the manner in which dates were encoded
and calculated. That failure could have a negative impact on the handling of
securities trades, pricing and account services.



    Improperly functioning trading systems may result in settlement problems and
liquidity issues. Corporate and governmental data processing errors could result
in production problems for individual issuers and overall economic
uncertainties. Operations ran smoothly from the last week in December through
the first few weeks of January, but the year 2000 issue may yet have an adverse
impact on financial market participants and other entities, including the
issuers whose securities are contained in the Fund's portfolio.


C. FUND POLICIES/INVESTMENT RESTRICTIONS

    The investment objectives, policies and restrictions listed below have been
adopted by the Fund as fundamental policies. Under the Investment Company Act of
1940 (the "Investment Company Act"), a fundamental policy may not be changed
without the vote of a majority of the outstanding voting securities of the Fund.
The Investment Company Act defines a majority as the lesser of (a) 67% or more
of the shares present at a meeting of shareholders, if the holders of 50% of the
outstanding shares of the Fund are present or represented by proxy; or (b) more
than 50% of the outstanding shares of the Fund. For purposes of the following
restrictions: (i) all percentage limitations apply immediately after a purchase
or initial investment; and (ii) any subsequent change in any applicable
percentage resulting from market fluctuations or other changes in total or net
assets does not require elimination of any security from the portfolio.

    The Fund will:

         1.  Seek to provide security of principal, high current income and
    liquidity.

    The Fund may not:

         1.  Purchase common stocks, preferred stocks, warrants, other equity
    securities, corporate bonds, municipal bonds or industrial revenue bonds.

         2.  Borrow money, except from banks for temporary or emergency
    purposes, including the meeting of redemption requests which might otherwise
    require the untimely disposition of securities; or through its transactions
    in reverse repurchase agreements. Borrowing in the aggregate, including
    reverse repurchase agreements, may not exceed 20%, and borrowing for
    purposes other than meeting redemptions may not exceed 5% of the value of
    the Fund's total assets (including the amount borrowed), less liabilities
    (not including the amount borrowed) at the time the borrowing is made.
    Borrowings in excess of 5% will be repaid before additional investments are
    made.

         3.  Pledge, hypothecate, mortgage or otherwise encumber its assets,
    except in an amount up to 10% of the value of its net assets, but only to
    secure borrowings for temporary or emergency purposes.

         4.  Sell securities short or purchase securities on margin.

         5.  Write or purchase put or call options.

         6.  Underwrite the securities of other issuers or purchase restricted
    securities except insofar as the Fund may enter into any repurchase or
    reverse repurchase agreements.

                                       6
<PAGE>
         7.  Purchase or sell real estate, real estate investment trust
    securities, commodities or commodity contracts or oil and gas interests.

         8.  Make loans to others, except: (a) by the purchase of qualified debt
    obligations; (b) lending portfolio securities; and (c) by investment in
    repurchase agreements referred to above and in the Prospectus.

         9.  Issue senior securities as defined in the Act except insofar as the
    Fund may be deemed to have issued a senior security by reason of: (a)
    entering into any repurchase or reverse repurchase agreement; (b) borrowing
    money in accordance with restrictions described above; or (c) lending
    portfolio securities.

        10.  Purchase securities of other investment companies, except in
    connection with a merger, consolidation, reorganization or acquisition of
    assets.

        11.  Lend its portfolio securities in excess of 10% of its total assets.
    Any loans of portfolio securities will be made according to guidelines
    established by the Trustees, including maintenance of cash collateral of the
    borrower equal at all times to the current market value of the securities
    loaned.

    Notwithstanding any other investment policy or restriction, the Fund may
seek to achieve its investment objective by investing all or substantially all
of its assets in another investment company having substantially the same
investment objective and policies as the Fund.

III. MANAGEMENT OF THE FUND
- --------------------------------------------------------------------------------

A. BOARD OF TRUSTEES

    The Board of Trustees of the Fund oversees the management of the Fund but
does not itself manage the Fund. The Trustees review various services provided
by or under the direction of the Investment Manager to ensure that the Fund's
general investment policies and programs are properly carried out. The Trustees
also conduct their review to ensure that administrative services are provided to
the Fund in a satisfactory manner.

    Under state law, the duties of the Trustees are generally characterized as a
duty of loyalty and a duty of care. The duty of loyalty requires a Trustee to
exercise his or her powers in the interest of the Fund and not the Trustee's own
interest or the interest of another person or organization. A Trustee satisfies
his or her duty of care by acting in good faith with the care of an ordinarily
prudent person and in a manner the Trustee reasonably believes to be in the best
interest of the Fund and its shareholders.

B. MANAGEMENT INFORMATION


    TRUSTEES AND OFFICERS.  The Board of the Fund consists of eight (8)
Trustees. These same individuals also serve as directors or trustees for all of
the Morgan Stanley Dean Witter Funds. Six Trustees (75% of the total number)
have no affiliation or business connection with the Investment Manager or any of
its affiliated persons and do not own any stock or other securities issued by
the Investment Manager's parent company, MSDW. These are the "non-interested" or
"independent" Trustees. The other two Trustees (the "management Trustees") are
affiliated with the Investment Manager.

    INDEPENDENT DIRECTORS/TRUSTEES AND THE COMMITTEES.  Law and regulation
establish both general guidelines and specific duties for the independent
directors/trustees. The Morgan Stanley Dean Witter Funds seek as independent
directors/trustees individuals of distinction and experience in business and
finance, government service or academia; these are people whose advice and
counsel are in demand by others and for whom there is often competition. To
accept a position on the Funds' boards, such individuals may reject other
attractive assignments because the Funds make substantial demands on their time.
All of the Independent Trustees serve as members of the Audit Committee. In
addition, three of the directors/trustees, including two independent
directors/trustees, serve as members of the Derivatives Committee and the
Insurance Committee.



    The independent directors/trustees are charged with recommending to the full
board approval of management, advisory and administration contracts, Rule 12b-1
plans and distribution and underwriting agreements; continually reviewing Fund
performance; checking on the pricing of portfolio securities, brokerage
commissions, transfer agent costs and performance, and trading among Funds in
the same complex; and approving fidelity bond and related insurance coverage and
allocations, as well as other matters that arise from time to time. The
independent directors/trustees are required to select and nominate individuals
to fill any independent director/trustee vacancy on the board of any Fund that
has a Rule 12b-1 plan of distribution. Most of the Morgan Stanley Dean Witter
Funds have a Rule 12b-1 plan.



    The Audit Committee is charged with recommending to the full board the
engagement or discharge of the Fund's independent accountants; directing
investigations into matters within the scope of the independent accountants'
duties, including the power to retain outside specialists; reviewing with the
independent accountants the audit plan and results of the auditing engagement;
approving professional services provided by the independent accountants and
other accounting firms prior to the performance of the services; reviewing the
independence of the independent accountants; considering the range of audit and
non-audit fees; reviewing the adequacy of the Fund's system of internal
controls; and preparing and submitting Committee meeting minutes to the full
board.



    The board of each Fund has a Derivatives Committee to approve parameters for
and monitor the activities of the Fund with respect to derivative investments,
if any, made by the Fund.



    Finally, the board of each Fund has formed an Insurance Committee to review
and monitor the insurance coverage maintained by the Fund.



    ADVANTAGES OF HAVING SAME INDIVIDUALS AS INDEPENDENT DIRECTORS/TRUSTEES FOR
ALL MORGAN STANLEY DEAN WITTER FUNDS.  The independent directors/trustees and
the Funds' management believe that having the same independent
directors/trustees for each of the Morgan Stanley Dean Witter Funds avoids the
duplication of effort that would arise from having different groups of
individuals serving as independent directors/trustees for each of the Funds or
even of sub-groups of Funds. They believe that having the same individuals serve
as independent directors/trustees of all the Funds tends to increase their
knowledge and expertise regarding matters which affect the Fund complex
generally and enhances


                                       11
<PAGE>

their ability to negotiate on behalf of each Fund with the Fund's service
providers. This arrangement also precludes the possibility of separate groups of
independent directors/trustees arriving at conflicting decisions regarding
operations and management of the Funds and avoids the cost and confusion that
would likely ensue. Finally, having the same independent directors/trustees
serve on all Fund boards enhances the ability of each Fund to obtain, at modest
cost to each separate Fund, the services of independent directors/trustees, of
the caliber, experience and business acumen of the individuals who serve as
independent directors/trustees of the Morgan Stanley Dean Witter Funds.


    TRUSTEE AND OFFICER INDEMNIFICATION.  The Fund's Declaration of Trust
provides that no Trustee, officer, employee or agent of the Fund is liable to
the Fund or to a shareholder, nor is any Trustee, officer, employee or agent
liable to any third persons in connection with the affairs of the Fund, except
as such liability may arise from his/her or its own bad faith, willful
misfeasance, gross negligence or reckless disregard of his/her or its duties. It
also provides that all third persons shall look solely to the Fund property for
satisfaction of claims arising in connection with the affairs of the 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 the Fund.

C. COMPENSATION


    The Fund pays each Independent Trustee an annual fee of $800 plus a per
meeting fee of $50 for meetings of the Board of Trustees, the Independent
Trustees or Committees of the Board of Trustees attended by the Trustee (the
Fund pays the Chairman of the Audit Committee an additional annual fee of $750
and the Chairmen of the Derivatives and Insurance Committees additional annual
fees of $500). If a Board meeting and a meeting of the Independent Trustees or a
Committee meeting, or a meeting of the Independent Trustees and/or more than one
Committee meeting, take place on a single day, the Trustees are paid a single
meeting fee by the Fund. The Fund also reimburses such Trustees for travel and
other out-of-pocket expenses incurred by them in connection with attending such
meetings. Trustees and officers of the Fund who are or have been employed by the
Investment Manager or an affiliated company receive no compensation or expense
reimbursement from the Fund for their services as Trustee.



    The following table illustrates the compensation that the Fund paid to its
Independent Trustees for the fiscal year ended January 31, 2000.

    As of the date of this STATEMENT OF ADDITIONAL INFORMATION, 55 of the Morgan
Stanley Dean Witter Funds, including the Fund, have adopted a retirement program
under which an independent director/ trustee who retires after serving for at
least five years (or such lesser period as may be determined by the Board) as an
independent director/trustee of any Morgan Stanley Dean Witter Fund that has
adopted the retirement program (each such Fund referred to as an "Adopting Fund"
and each such director/trustee referred to as an "Eligible Trustee") is entitled
to retirement payments upon reaching the eligible retirement age (normally,
after attaining age 72). Annual payments are based upon length of service.



    Currently, upon retirement, each Eligible Trustee is entitled to receive
from the Adopting Fund, commencing as of his or her retirement date and
continuing for the remainder of his or her life, an annual retirement benefit
(the "Regular Benefit") equal to 30.22% of his or her Eligible Compensation plus
0.5036667% of such Eligible Compensation for each full month of service as an
independent director/ trustee of any Adopting Fund in excess of five years up to
a maximum of 60.44% after ten years of service. The foregoing percentages may be
changed by the Board.(1) "Eligible Compensation" is one-fifth of the total
compensation earned by such Eligible Trustee for service to the Adopting Fund in
the five year period prior to the date of the Eligible Trustee's retirement.
Benefits under the retirement program are accrued as expenses on the books of
the Adopting Funds. Such benefits are not secured or funded by the Adopting
Funds.



    The following table illustrates the retirement benefits accrued to the
Fund's Independent Trustees by the Fund for the fiscal year ended January 31,
2000 and by the 55 Morgan Stanley Dean Witter Funds (including the Fund) for the
year ended December 31, 1999, and the estimated retirement benefits for the
Independent Trustees, to commence upon their retirement, from the Fund as of
January 31, 2000 and from the 55 Morgan Stanley Dean Witter Funds as of December
31, 1999.


- ------------------------
(1)  An Eligible Trustee may elect alternative payments of his or her retirement
     benefits based upon the combined life expectancy of the Eligible Trustee
     and his or her spouse on the date of such Eligible Trustee's retirement. In
     addition, the Eligible Trustee may elect that the surviving spouse's
     periodic payment of benefits will be equal to a lower percentage of the
     periodic amount when both spouses were alive. The amount estimated to be
     payable under this method, through the remainder of the later of the lives
     of the Eligible Trustee and spouse, will be the actuarial equivalent of the
     Regular Benefit.

provide administrative services and manage the investment of the Fund's assets,
including the placing of orders for the purchase and sale of portfolio
securities. The Fund pays the Investment Manager monthly compensation calculated

B. PRINCIPAL UNDERWRITER

    The Fund's principal underwriter is the Distributor (which has the same

dealer agreement with Dean Witter Reynolds, which through its own sales
organization sells shares of the Fund. In addition, the Distributor may enter
into similar agreements with other selected broker-dealers. The Distributor, a

    The Fund and the Distributor have agreed to indemnify each other against
certain liabilities, including liabilities under the Securities Act. Under the
Distribution Agreement, the Distributor uses its best efforts in rendering
services to the Fund, but in the absence of willful misfeasance, bad faith,
gross negligence or reckless disregard of its obligations, the Distributor is
not liable to the Fund or any of its shareholders for any error of judgment or
mistake of law or for any act or omission or for any losses sustained by the
Fund or its shareholders.


C. SERVICES PROVIDED BY THE INVESTMENT MANAGER

it considers necessary or useful to continuously manage the assets of the Fund
in a manner consistent with its investment objective.

    Under the terms of the Management Agreement, in addition to managing the
Fund's investments, the Investment Manager maintains certain of the Fund's books
and records and furnishes, at its own expense, the office space, facilities,
equipment, clerical help, bookkeeping and certain legal services as the Fund may
reasonably require in the conduct of its business, including the preparation of
prospectuses, proxy statements and reports required to be filed with federal and
state securities commissions (except insofar as the participation or assistance
of independent accountants and attorneys is, in the opinion of the Investment
Manager, necessary or desirable). In addition, the Investment Manager pays the
salaries of all personnel, including officers of the Fund, who are employees of
the Investment Manager. The Investment Manager also bears the cost of telephone
service, heat, light, power and other utilities provided to the Fund.

    Expenses not expressly assumed by the Investment Manager under the
Management Agreement or by the Distributor, will be paid by the Fund. These
expenses include, but are not limited to: expenses of the Plan of Distribution
pursuant to Rule 12b-1; charges and expenses of any registrar, custodian, stock
transfer and dividend disbursing agent; brokerage commissions; taxes; engraving
and printing share certificates; registration costs of the Fund and its shares
under federal and state securities laws; the cost and expense of printing,
including typesetting, and distributing prospectuses of the Fund and supplements
thereto to the Fund's shareholders; all expenses of shareholders' and Trustees'
meetings and of preparing, printing and mailing of proxy statements and reports
to shareholders; fees and travel expenses of Trustees or members of any advisory
board or committee who are not employees of the Investment Manager or any
corporate affiliate of the Investment Manager; all expenses incident to any
dividend, withdrawal or redemption options; charges and expenses of any outside
service used for pricing of the Fund's shares; fees and expenses of legal
counsel, including counsel to the Trustees who are not interested persons of the
Fund or of the Investment Manager (not including compensation or expenses of
attorneys who are employees of the Investment Manager); fees and expenses of the
Fund's independent accountants; membership dues of industry associations;
interest on Fund borrowings; postage; insurance premiums on property or
personnel (including officers and Trustees) of the Fund which inure to its
benefit; extraordinary expenses (including, but not limited to, legal claims and
liabilities and litigation costs and any indemnification relating thereto); and
all other costs of the Fund's operation.

                                       15

    The Management Agreement provides that in the absence of willful
misfeasance, bad faith, gross negligence or reckless disregard of its
obligations thereunder, the Investment Manager is not liable to the Fund or any
of its investors for any act or omission by the Investment Manager or for any
losses sustained by the Fund or its investors.


    The Management Agreement will remain in effect from year to year, provided
continuance of the Management Agreement is approved at least annually by the
vote of the holders of a majority, as defined in the Investment Company Act, of
the outstanding shares of the Fund, or by the Trustees; provided that in either
event such continuance is approved annually by the vote of a majority of the
Trustees, including a majority of the Independent Trustees.


D. RULE 12b-1 PLAN

    In accordance with a Plan of Distribution pursuant to Rule 12b-1 under the
Investment Company Act between the Fund and the Distributor, the Distributor
provides certain services in connection with the promotion of sales of Fund
shares (the "Plan").

    The Plan provides that the Distributor bears the expense of all promotional
and distribution related activities on behalf of the Fund, except for expenses
that the Trustees determine to reimburse, as described below. The following
activities and services may be provided by the Distributor under the Plan: (1)
compensation to and expenses of Dean Witter Reynolds' and other selected
Broker-Dealers' Financial Advisors and other employees, including overhead and
telephone expenses; (2) sales incentives and bonuses to sales representatives
and to marketing personnel in connection with promoting sales of the Fund's
shares; (3) expenses incurred in connection with promoting sales of the Fund's
shares; (4) preparing and distributing sales literature; and (5) providing
advertising and promotional activities, including direct mail solicitation and
television, radio, newspaper, magazine and other media advertisements.


    The Investment Manager will compensate Financial Advisors at an annual rate
of 0.025% of the value of shares of the Fund acquired by exchange from an MSDW
Open-end Fund provided that the shares exchanged would otherwise have been
eligible for the payment of a retention fee. Such eligible shares must have been
purchased after January 1, 2000 and held for at least one year. Shares owned in
variable annuities, closed-end fund shares held in 401(k) plans where the
Transfer Agent or Dean Witter Reynolds' Retirement Plan Services is either
recordkeeper or trustee are not eligible for a retention fee.



    The retention fees are paid by the Investment Manager from its own assets,
which may include profits from investment management fees payable under the
Management Agreement, as well as from borrowed funds.



    Dean Witter Reynolds' Financial Advisors are paid an annual residual
commission, currently a residual of up to 0.10% of the current value of the
respective accounts for which they are the Financial Advisors of record. The
residual is a charge which reflects residual commissions paid by Dean Witter
Reynolds to its Financial Advisors and Dean Witter Reynolds' expenses associated
with the servicing of shareholders' accounts, including the expenses of
operating Dean Witter Reynolds' branch offices in connection with the servicing
of shareholders' accounts, which expenses include lease costs, the salaries and
employee benefits of operations and sales support personnel, utility costs,
communications costs and the costs of stationery and supplies and other expenses
relating to branch office serving of shareholder accounts.


    The Fund is authorized to reimburse specific expenses incurred or to be
incurred in promoting the distribution of the Fund's shares. Reimbursement is
made through payments at the end of each month. The amount of each monthly
payment may in no event exceed an amount equal to a payment at the annual rate
of 0.15 of 1% of the Fund's average daily net assets during the month. No
interest or other financing charges will be incurred for which reimbursement
payments under the Plan will be made. In addition, no interest charges, if any,
incurred on any distribution expense incurred by the Distributor or other
selected dealers pursuant to the Plan, will be reimbursable under the Plan. In
the case of all expenses other than expenses representing a residual to
Financial Advisors, such amounts shall be

                                       16
<PAGE>
determined at the beginning of each calendar quarter by the Trustees, including
a majority of the Independent 12b-1 Trustees. Expenses representing a residual
to Financial Advisors may be reimbursed without prior determination. In the
event that the Distributor proposes that monies shall be reimbursed for other
than such expenses, then in making quarterly determinations of the amounts that
may be expended by the Fund, the Investment Manager provides and the Trustees
review a quarterly budget of projected incremental distribution expenses to be
incurred on behalf of the Fund, together with a report explaining the purposes
and anticipated benefits of incurring such expenses. The Trustees determine
which particular expenses, and the portions thereof, that may be borne by the
Fund, and in making such a determination shall consider the scope of the
Distributor's commitment to promoting the distribution of the Fund's shares.


    The Fund reimbursed $795,443 to the Distributor pursuant to the Plan which
amounted to .08% of the Fund's average daily net assets for the fiscal year
ended January 31, 2000. Based upon the total amounts spent by the Distributor
during the period, it is estimated that the amount paid by the Fund to the
Distributor for distribution was spent in approximately the following ways: (i)
advertising -- $-0-; (ii) printing and mailing PROSPECTUSES to other than
current shareholders -- $-0-; (iii) compensation to underwriters -- $-0-; (iv)
compensation to dealers --$-0-; (v) compensation to sales personnel -- $-0-; and
(vi) other, which includes payments to Dean Witter Reynolds for expenses
substantially all of which relate to compensation of sales personnel and
associated overhead expenses -- $795,443. No payments under the Plan were made
for interest, carrying or other financing charges.


    Under the Plan, the Distributor uses its best efforts in rendering services
to the Fund, but in the absence of willful misfeasance, bad faith, gross
negligence or reckless disregard of its obligations, the Distributor is not
liable to the Fund or any of its shareholders for any error of judgment or
mistake of law or for any act or omission or for any losses sustained by the
Fund or its shareholders.

    Under the Plan, the Distributor provides the Fund, for review by the
Trustees, and the Trustees review, promptly after the end of each calendar
quarter, a written report regarding the incremental distribution expenses
incurred on behalf of the Fund during such calendar quarter, which report
includes (1) an itemization of the types of expenses and the purposes therefore;
(2) the amounts of such expenses; and (3) a description of the benefits derived
by the Fund. In the Trustees' quarterly review of the Plan they consider its
continued appropriateness and the level of compensation provided therein.

    No interested person of the Fund nor any Independent Trustee has any direct
financial interest in the operation of the Plan except to the extent that the
Distributor, the Investment Manager, Dean Witter Reynolds, MSDW Services Company
or certain of their employees may be deemed to have such an interest as a result
of benefits derived from the successful operation of the Plan or as a result of
receiving a portion of the amounts expended thereunder by the Fund.


    On an annual basis, the Trustees, including a majority of the Independent
Trustees, consider whether the Plan should be continued. Prior to approving the
most recent continuation of the Plan, the Trustees requested and received from
the Distributor and reviewed all the information which they deemed necessary to
arrive at an informed determination. In making their determination to continue
the Plan, the Trustees considered: (1) the Fund's experience under the Plan and
whether such experience indicates that the Plan is operating as anticipated;
(2) the benefits the Fund had obtained, was obtaining and would be likely to
obtain under the Plan, including that: (a) the Plan is essential in order to
implement the Fund's method of distribution and to enable the Fund to continue
to grow and avoid a pattern of net redemptions which, in turn, are essential for
effective investment management; and (b) without the reimbursement of
distribution and account maintenance expenses of Dean Witter Reynolds' branch
offices made possible by the 12b-1 fees, Dean Witter Reynolds could not
establish and maintain an effective system for distribution, servicing of Fund
shareholders and maintenance of shareholder accounts; and (3) what services had
been provided and were continuing to be provided under the Plan to the Fund and
its shareholders. Based upon their review, the Trustees, including each of the
Independent Trustees, determined that continuation of the Plan would be in the
best interest of the Fund and would have a reasonable likelihood of continuing
to benefit the Fund and its shareholders. In the Trustees' quarterly review of
the Plan, they will consider its continued appropriateness and the level of
compensation provided therein.


                                       17
<PAGE>
    The Plan may not be amended to increase materially the amount to be spent
for the services described therein without approval by the shareholders of the
Fund, and all material amendments to the Plan must also be approved by the
Trustees in the manner described above. The Plan may be terminated at any time,
without payment of any penalty, by vote of a majority of the Independent
Trustees or by a vote of a majority of the outstanding voting securities of the
Fund (as defined in the Investment Company Act) on not more than thirty days'
written notice to any other party to the Plan. So long as the Plan is in effect,
the election and nomination of Independent Trustees shall be committed to the
discretion of the Independent Trustees.

E. OTHER SERVICE PROVIDERS

(1) TRANSFER AGENT/DIVIDEND-PAYING AGENT


    Morgan Stanley Dean Witter Trust FSB is the transfer agent for the Fund's
shares and the Dividend Disbursing Agent for payment of dividends and
distributions on Fund shares and Agent for shareholders under various investment
plans. The principal business address of the Transfer Agent is Harborside
Financial Center, Plaza Two, Jersey City, NJ 07311.


(2) CUSTODIAN AND INDEPENDENT ACCOUNTANTS


    The Bank of New York, 100 Church Street, New York, NY 10007 is the Custodian
for the Fund's assets. Any of the Fund's cash balances with the Custodian in
excess of $100,000 are unprotected by federal deposit insurance. These balances
may, at times, be substantial.



    PricewaterhouseCoopers LLP, 1177 Avenue of the Americas, New York, NY 10036
serves as the independent accountants of the Fund. The independent accountants
are responsible for auditing the annual financial statements of the Fund.


(3) AFFILIATED PERSONS


    The Transfer Agent is an affiliate of the Investment Manager, and of the
Distributor. As Transfer Agent and Dividend Disbursing Agent, the Transfer
Agent's responsibilities include maintaining shareholder accounts, disbursing
cash dividends and reinvesting dividends, processing account registration
changes, handling purchase and redemption transactions, mailing prospectuses and
reports, mailing and tabulating proxies, processing share certificate
transactions, and maintaining shareholder records and lists. For these services,
the Transfer Agent receives a per shareholder account fee from the Fund and is
reimbursed for its out-of-pocket expenses in connection with such services.



F. CODES OF ETHICS



    The Fund, the Investment Manager and the Distributor have each adopted a
Code of Ethics pursuant to Rule 17j-1 under the Investment Company Act. The
Codes of Ethics are designed to detect and prevent improper personal trading.
The Codes of Ethics permit personnel subject to the Codes to invest in
securities, including securities that may be purchased, sold or held by the
Fund, subject to a number of restrictions and controls including prohibitions
against purchases of securities in an Initial Public Offering and a preclearance
requirement with respect to personal securities transactions.


VI. BROKERAGE ALLOCATION AND OTHER PRACTICES
- --------------------------------------------------------------------------------

A. BROKERAGE TRANSACTIONS

    Subject to the general supervision of the Trustees, the Investment Manager
is responsible for decisions to buy and sell securities for the Fund, the
selection of brokers and dealers to effect the transactions, and the negotiation
of brokerage commissions, if any. Purchases and sales of portfolio securities
are normally transacted through issuers, underwriters or major dealers in U.S.
Government securities acting as principals. Such transactions are made on a net
basis and do not involve payment of brokerage commissions. The cost of
securities purchased from an underwriter usually includes a commission paid by
the issuer to the underwriters; transactions with dealers normally reflect the
spread between bid and asked prices.


    During the fiscal years ended January 31, 1998, 1999 and 2000, the Fund paid
no such brokerage commissions or concessions.


                                       18
<PAGE>
B. COMMISSIONS

    Pursuant to an order of the SEC, the Fund may effect principal transactions
in certain money market instruments with Dean Witter Reynolds. The Fund will
limit its transactions with Dean Witter Reynolds to U.S. Government and
Government Agency Securities. The transactions will be effected with Dean Witter
Reynolds only when the price available from Dean Witter Reynolds is better than
that available from other dealers.


    During the fiscal years ended January 31, 1998, 1999 and 2000, the Fund did
not effect any principal transactions with Dean Witter Reynolds.



    Brokerage transactions in securities listed on exchanges or admitted to
unlisted trading privileges may be effected through Dean Witter Reynolds, Morgan
Stanley & Co. and other affiliated brokers and dealers. In order for an
affiliated broker or dealer to effect any portfolio transactions on an exchange
for the Fund, the commissions, fees or other remuneration received by the
affiliated broker or dealer must be reasonable and fair compared to the
commissions, fees or other remuneration paid to other brokers in connection with
comparable transactions involving similar securities being purchased or sold on
an exchange during a comparable period of time. This standard would allow the
affiliated broker or dealer to receive no more than the remuneration which would
be expected to be received by an unaffiliated broker in a commensurate
arm's-length transaction. Furthermore, the Trustees, including the Independent
Trustees, have adopted procedures which are reasonably designed to provide that
any commissions, fees or other remuneration paid to an affiliated broker or
dealer are consistent with the foregoing standard. The Fund does not reduce the
management fee it pays to the Investment Manager by any amount of the brokerage
commissions it may pay to an affiliated broker or dealer.



    During the fiscal years ended January 31, 1998, 1999 and 2000, the Fund paid
no brokerage commissions to an affiliated broker or dealer.


C. BROKERAGE SELECTION

    The policy of the Fund regarding purchases and sales of securities for its
portfolio is that primary consideration will be given to obtaining the most
favorable prices and efficient executions of transactions.

    In seeking to implement the Fund's policies, the Investment Manager effects
transactions with those brokers and dealers who the Investment Manager believes
provide the most favorable prices and are capable of providing efficient
executions. If the Investment Manager believes the prices and executions are
obtainable from more than one broker or dealer, it may give consideration to
placing portfolio transactions with those brokers and dealers who also furnish
research and other services to the Fund or the Investment Manager. The services
may include, but are not limited to, any one or more of the following:
information as to the availability of securities for purchase or sale;
statistical or factual information or opinions pertaining to investment; wire
services; and appraisals or evaluations of portfolio securities.

    The information and services received by the Investment Manager from brokers
and dealers may be of benefit to the Investment Manager in the management of
accounts of some of its other clients and may not in all cases benefit the Fund
directly. While the receipt of such information and services is useful in
varying degrees and would generally reduce the amount of research or services
otherwise performed by the Investment Manager and thereby reduce its expenses,
it is of indeterminable value and the Fund does not reduce the management fee it
pays to the Investment Manager by any amount that may be attributable to the
value of such services.

    Subject to the principle of obtaining best price and execution, the
Investment Manager may consider a broker-dealer's sales of shares of the Fund as
a factor in selecting from among those broker-dealers qualified to provide
comparable prices and execution on the Fund's portfolio transactions. The Fund
does not, however, require a broker-dealer to sell shares of the Fund in order
for it to be considered to execute portfolio transactions, and will not enter
into any arrangement whereby a specific amount or

                                       19
<PAGE>
percentage of the Fund's transactions will be directed to a broker which sells
shares of the Fund to customers. The Trustees review, periodically, the
allocation of brokerage orders to monitor the operation of these policies.

    The Investment Manager currently serves as investment manager to a number of
clients, including other investment companies, and may in the future act as
investment manager or advisor to others. It is the practice of the Investment
Manager to cause purchase and sale transactions to be allocated among the Fund
and others whose assets it manages in such manner as it deems equitable. In
making such allocations among the Fund and other client accounts, various
factors may be considered, including the respective investment objectives, the
relative size of portfolio holdings of the same or comparable securities, the
availability of cash for investment, the size of investment commitments
generally held and the opinions of the persons responsible for managing the
portfolios of the Fund and other client accounts. In the case of certain initial
and secondary public offerings, the Investment Manager utilizes a pro rata
allocation process based on the size of the Morgan Stanley Dean Witter Funds
involved and the number of shares available from the public offering.

D. DIRECTED BROKERAGE


    During the fiscal year ended January 31, 2000, the Fund did not pay any
brokerage commissions to brokers because of research services provided.


E. REGULAR BROKER-DEALERS


    During the fiscal year ended January 31, 2000, the Fund did not purchase
securities issued by brokers or dealers that were among the ten brokers or the
ten dealers which executed transactions for or with the Fund in the largest
dollar amounts during the year. At January 31, 2000, the Fund did not own any
securities issued by any of such issuers.


VII. CAPITAL STOCK AND OTHER SECURITIES
- --------------------------------------------------------------------------------

    The shareholders of the Fund are entitled to a full vote for each full share
of beneficial interest held. The Fund is authorized to issue an unlimited number
of shares of beneficial interest. All shares of beneficial interest of the Fund
are of $0.01 par value and are equal as to earnings, assets and voting
privileges.

    The Fund's Declaration of Trust permits the Trustees to authorize the
creation of additional series of shares (the proceeds of which would be invested
in separate, independently managed portfolios) and additional Classes of shares
within any series. The Trustees have not presently authorized any such
additional series or Classes of shares other than as set forth in the
PROSPECTUS.


    The Fund is not required to hold annual meetings of shareholders and in
ordinary circumstances the Fund does not intend to hold such meetings. The
Trustees may call special meetings of shareholders for action by shareholder
vote as may be required by the Investment Company Act or the Declaration of
Trust. Under certain circumstances, the Trustees may be removed by the actions
of the Trustees. In addition, under certain circumstances, the shareholders may
call a meeting to remove the Trustees and the Fund is required to provide
assistance in communicating with shareholders about such a meeting. The voting
rights of shareholders are not cumulative, so that holders of more than 50
percent of the shares voting can, if they choose, elect all Trustees being
selected, while the holders of the remaining shares would be unable to elect any
Trustees.


    Under Massachusetts law, shareholders of a business trust may, under certain
limited circumstances, be held personally liable as partners for the obligations
of the Fund. However, the Declaration of Trust contains an express disclaimer of
shareholder liability for acts or obligations of the Fund, requires that notice
of such Fund obligations include such disclaimer, and provides for
indemnification out of the Fund's property for any shareholder held personally
liable for the obligations of the Fund. Thus, the risk of a shareholder
incurring financial loss on account of shareholder liability is limited to
circumstances in which the Fund itself would be unable to meet its obligations.
Given the above limitations on shareholder

                                       20
<PAGE>
personal liability, and the nature of the Fund's assets and operations, the
possibility of the Fund being unable to meet its obligations is remote and thus,
in the opinion of Massachusetts counsel to the Fund, the risk to Fund
shareholders of personal liability is remote.

    All of the Trustees have been elected by the shareholders of the Fund, most
recently at a Special Meeting of Shareholders held on May 21, 1997. The Trustees
themselves have the power to alter the number and the terms of office of the
Trustees (as provided for in the Declaration of Trust), and they may at any time
lengthen or shorten their own terms or make their terms of unlimited duration
and appoint their own successors, provided that always at least a majority of
the Trustees has been elected by the shareholders of the Fund.

VIII. PURCHASE, REDEMPTION AND PRICING OF SHARES
- --------------------------------------------------------------------------------

A. PURCHASE/REDEMPTION OF SHARES

    Information concerning how Fund shares are offered to the public (and how
they are redeemed and exchanged) is provided in the Fund's PROSPECTUS.

    TRANSFER AGENT AS AGENT.  With respect to the redemption or repurchase of
Fund shares, the application of proceeds to the purchase of new shares in the
Fund or any other Morgan Stanley Dean Witter Funds and the general
administration of the exchange privilege, the Transfer Agent acts as agent for
the Distributor and for the shareholder's authorized broker-dealer, if any, in
the performance of such functions. With respect to exchanges, redemptions or
repurchases, the Transfer Agent shall be liable for its own negligence and not
for the default or negligence of its correspondents or for losses in transit.
The Fund shall not be liable for any default or negligence of the Transfer
Agent, the Distributor or any authorized broker-dealer.

    The Distributor and any authorized broker-dealer have appointed the Transfer
Agent to act as their agent in connection with the application of proceeds of
any redemption of Fund shares to the purchase of shares of any other Morgan
Stanley Dean Witter Fund and the general administration of the exchange
privilege. No commission or discounts will be paid to the Distributor or any
authorized broker-dealer for any transaction pursuant to the exchange privilege.

    REDEMPTIONS.  A check drawn by a shareholder against his or her account in
the Fund constitutes a request for redemption of a number of shares sufficient
to provide proceeds equal to the amount of the check. Payment of the proceeds
will normally be made on the next business day after receipt by the Transfer
Agent of the check in proper form. If a check is presented for payment to the
Transfer Agent by a shareholder or payee in person, the Transfer Agent will make
payment by means of a check drawn on the Fund's account or, in the case of a
shareholder payee, to the shareholder's predesignated bank account, but will not
make payment in cash.

B. OFFERING PRICE

    The price of Fund shares, called "net asset value," is based on the value of
the Fund's portfolio securities.

    The Fund utilizes the amortized cost method in valuing its portfolio
securities for purposes of determining the net asset value of its shares. The
Fund utilizes the amortized cost method in valuing its portfolio securities even
though the portfolio securities may increase or decrease in market value,
generally in connection with changes in interest rates. The amortized cost
method of valuation involves valuing a security at its cost at the time of
purchase adjusted by a constant amortization to maturity of any discount or
premium, regardless of the impact of fluctuating interest rates on the market
value of the instrument. While this method provides certainty in valuation, it
may result in periods during which value, as determined by amortized cost, is
higher or lower than the price the Fund would receive if it sold the investment.
During such periods, the yield to investors in the Fund may differ somewhat from
that obtained in a similar company which uses market-to-market values for all of
its portfolio securities. For example, if the use of amortized cost resulted in
a lower (higher) aggregate portfolio value on a particular day, a prospective
investor in the Fund would be able to obtain a somewhat higher (lower) yield
than

                                       21
<PAGE>
would result from investment in such a similar company and existing investors
would receive less (more) investment income. The purpose of this method of
calculation is to facilitate the maintenance of a constant net asset value per
share of $1.00.

    The use of the amortized cost method to value the portfolio securities of
the Fund and the maintenance of the per share net asset value of $1.00 is
permitted pursuant to Rule 2a-7 of the Act (the "Rule") and is conditioned on
its compliance with various conditions contained in the Rule including: (a) the
Trustees are obligated, as a particular responsibility within the overall duty
of care owed to the Fund's shareholders, to establish procedures reasonably
designed, taking into account current market conditions and the Fund's
investment objectives, to stabilize the net asset value per share as computed
for the purpose of distribution and redemption at $1.00 per share; (b) the
procedures include (i) calculation, at such intervals as the Trustees determine
are appropriate and as are reasonable in light of current market conditions, of
the deviation, if any, between net asset value per share using amortized cost to
value portfolio securities and net asset value per share based upon available
market quotations with respect to such portfolio securities; (ii) periodic
review by the Trustees of the amount of deviation as well as methods used to
calculate it; and (iii) maintenance of written records of the procedures, and
the Trustees' considerations made pursuant to them and any actions taken upon
such consideration; (c) the Trustees should consider what steps should be taken,
if any, in the event of a difference of more than 1/2 of 1% between the two
methods of valuation; and (d) the Trustees should take such action as they deem
appropriate (such as shortening the average portfolio maturity, realizing gains
or losses, withholding dividends or, as provided by the Declaration of Trust,
reducing the number of outstanding shares of the Fund) to eliminate or reduce to
the extent reasonably practicable material dilution or other unfair results to
investors or existing shareholders which might arise from differences between
the two method of valuation.

    Generally, for purposes of the procedures adopted under the Rule, the
maturity of a portfolio security is deemed to be the period remaining
(calculated from the trade date or such other date on which the Fund's interest
in the instrument is subject to market action) until the date on which in
accordance with the terms of the security the principal amount must
unconditionally be paid, or in the case of a security called for redemption, the
date on which the redemption payment must be made.

    A variable rate security that is subject to a demand feature is deemed to
have a maturity equal to the period remaining until the principal amount can be
recovered through demand. A floating rate security that is subject to a demand
feature is deemed to have a maturity equal to the period remaining until the
principal amount can be recovered through demand.

    An "NRSRO" is a nationally recognized statistical rating organization. The
term "Requisite NRSROs" means (i) any two NRSROs that have issued a rating with
respect to a security or class of debt obligations of an issuer, or (ii) if only
one NRSRO has issued a rating with respect to such security or issuer at the
time a fund purchases or rolls over the security, that NRSRO.

    An Eligible Security is generally defined in the Rule to mean (i) a rated
security with a remaining maturity of 397 calendar days or less that has
received a rating from the Requisite NRSROs in one of the two highest short-term
rating categories (within which there may be sub-categories or gradations
indicating relative standing); or (ii) An Unrated Security that is of comparable
quality to a security meeting the requirements of (1) above, as determined by
Trustees; (iii) In addition, in the case of a security that is subject to a
Demand Feature or Guarantee: (A) The Guarantee has received a rating from an
NRSRO or the Guarantee is issued by a guarantor that has received a rating from
an NRSRO with respect to a class of debt obligations (or any debt obligation
within that class) that is comparable in priority and security to the Guarantee,
unless: (1) the Guarantee is issued by a person that directly or indirectly,
controls, is controlled by or is under a common control with the issuer of the
security subject to the Guarantee (other than a sponsor or a Special Purpose
Entity with respect to an Asset Backed Security: (2) the security subject to the
Guarantee is a repurchase agreement that is Collateralized Fully; or (3) the
Guarantee itself is a Government Security and (B) the issuer of the Demand
Feature, or another institution, has undertaken promptly to notify the holder of
the security in the event the Demand Feature

                                       22
<PAGE>
or Guarantee is substituted with another Demand Feature or Guarantee (if such
substitution is permissible under the terms of the Demand Feature or Guarantee).
The Fund will limit its investments to securities that meet the requirements for
Eligible Securities.

    As permitted by the Rule, the Trustees have delegated to the Fund's
Investment Manager the authority to determine which securities present minimal
credit risks and which unrated securities are comparable in quality to rated
securities.

    Also, as required by the Rule, the Fund will limit its investments in
securities, other than Government securities, so that, at the time of purchase:
(a) except as further limited in (b) below with regard to certain securities, no
more than 5% of its total assets will be invested in the securities of any one
issuer; and (b) with respect to Eligible Securities that have received a rating
in less than the highest category by any one of the NRSROs whose ratings are
used to qualify the security as an Eligible Security, or that have been
determined to be of comparable quality: (i) no more than 5% in the aggregate of
the Fund's total assets in all such securities, and (ii) no more than the
greater of 1% of total assets, or $1 million, in the securities on any one
issuer.

    The Rule further requires that the Fund limit its investments to U.S.
dollar-denominated instruments which the Trustees determine present minimal
credit risks and which are Eligible Securities. The Rule also requires the Fund
to maintain a dollar-weighted average portfolio maturity (not more than 90 days)
appropriate to its objective of maintaining a stable net asset value of $1.00
per share and precludes the purchase of any instrument with a remaining maturity
of more than 397 days. Should the disposition of a portfolio security result in
a dollar-weighted average portfolio maturity of more than 90 days, the Fund will
invest its available cash in such a manner as to reduce such maturity to 90 days
or less a soon as is reasonably practicable.

    If the Trustees determine that it is no longer in the best interests of the
Fund and its shareholders to maintain a stable price of $1 per share or if the
Trustees believe that maintaining such price no longer reflects a market-based
net asset value per share, the Trustees have the right to change from an
amortized cost basis of valuation to valuation based on market quotations. The
Fund will notify shareholders of the Fund of any such change.

IX. TAXATION OF THE FUND AND SHAREHOLDERS
- --------------------------------------------------------------------------------

    The Fund intends to distribute all of its daily net investment income (and
net short-term capital gains, if any) to shareholders of record as of the close
of business the preceding business day. Net income, for dividend purposes,
includes accrued interest and amortization of acquisition, original issue and
market discount, plus or minus any short-term gains or losses realized on sales
of portfolio securities, less the amortization of market premium and the
estimated expenses of the Fund. Net income will be calculated immediately prior
to the determination of net asset value per share of the Fund.

    The Trustees of the Fund may revise the dividend policy, or postpone the
payment of dividends, if the Fund should have or anticipate any large unexpected
expense, loss or fluctuation in net assets which, in the opinion of the
Trustees, might have a significant adverse effect on shareholders. On occasion,
in order to maintain a constant $1.00 per share net asset value, the Trustees
may direct that the number of outstanding shares be reduced in each
shareholder's account. Such reduction may result in taxable income to a
shareholder in excess of the net increase (i.e., dividends, less such
reductions), if any, in the shareholder's account for a period of time.
Furthermore, such reduction may be realized as a capital loss when the shares
are liquidated.

    It has been and remains the Trust's policy and practice that, if checks for
dividends or distributions paid in cash remain uncashed, no interest will accrue
on amounts represented by such uncashed checks.

                                       23
<PAGE>

    INVESTMENT COMPANY TAXATION.  The Fund has qualified and intends to remain
qualified as a regulated investment company under Subchapter M of the Internal
Revenue Code. If so qualified, the Fund will not be subject to federal income
taxes, provided that it distributes all of its taxable net investment income and
all of its net realized gains.



    Gains or losses on sales of securities held by the Fund will be long-term
capital gains or losses if the securities have a tax holding period of more than
one year. Gains or losses on the sale of securities with a tax holding period of
one year or less will be short-term gains or losses.



    Under present Massachusetts law, the Fund is not subject to any
Massachusetts income tax during any fiscal year in which the Fund qualifies as a
regulated investment company. The Fund might be subject to Massachusetts income
taxes for any taxable year in which it does not so qualify as a regulated
investment company.



    The Fund may be subject to tax or taxes in certain states where it does
business. Furthermore, in those states which have income tax laws, the tax
treatment of the Fund and of shareholders with respect to distributions by the
Fund may differ from federal tax treatment.



    TAXATION OF DIVIDENDS AND DISTRIBUTIONS.  Shareholders will normally be
subject to federal income tax, and any state and local income taxes, on
dividends paid from interest income derived from taxable securities and on
distributions of realized net short-term capital gains and long-term capital
gains. Interest and realized net short-term capital gains distributions are
taxable to the shareholder as ordinary dividend income regardless of whether the
shareholder receives such distributions in additional shares or in cash. Since
the Trust's income is expected to be derived entirely from interest rather than
dividends, none of such distributions will be eligible for the federal dividends
received deduction available to corporations. Realized net long-term capital
gains distributions, if any, are taxable as long-term capital gains, regardless
of how long the shareholder has held the Fund shares and regardless of whether
the distribution is received in additional shares or in cash. Realized net
long-term capital gains distributions are not eligible for the dividends
received deduction.



    Shareholders who are not citizens or residents of the United States and
certain foreign entities may be subject to withholding of United States tax on
distributions made by the Fund of any taxable interest income and short-term
capital gains.



    After the end of each calendar year, shareholders will be sent information
on their dividends and capital gain distributions for tax purposes, including
the portion taxable as ordinary income, the portion taxable as long-term capital
gains and the amount of any dividends eligible for the federal dividends
received deduction for corporations.


    Shareholders are urged to consult their own tax advisors regarding specific
questions as to federal, state or local taxes.

X. UNDERWRITERS
- --------------------------------------------------------------------------------


    The Fund's shares are offered to the public on a continuous basis. The
Distributor, as the principal underwriter of the shares, has certain obligations
under the Distribution Agreement concerning the distribution of the shares.
These obligations and the compensation the Distributor receives are described
above in the sections titled "Principal Underwriter" and "Rule 12b-1 Plan."


XI. CALCULATION OF PERFORMANCE DATA
- --------------------------------------------------------------------------------


    The Fund's current yield for the seven days ending January 31, 2000 was
4.90%. The seven day effective yield on January 31, 2000, was 5.02% assuming
daily compounding.


    The Fund's annualized current yield, as may be quoted from time to time in
advertisements and other communications to shareholders and potential investors,
is computed by determining, for a stated seven-day period, the net change,
exclusive of capital changes and including the value of additional

                                       24
<PAGE>
shares purchased with dividends and any dividends declared therefrom (which
reflect deductions of all expenses of the Fund such as management fees), in the
value of a hypothetical pre-existing account having a balance of one share at
the beginning of the period, and dividing the difference by the value of the
account at the beginning of the base period to obtain the base period return,
and then multiplying the base period return by (365/7).

    The Fund's annualized effective yield, as may be quoted from time to time in
advertisements and other communications to shareholders and potential investors,
is computed by determining (for the same stated seven-day period as for the
current yield), the net change, exclusive of capital changes and including the
value of additional shares purchased with dividends and any dividends declared
therefrom (which reflect deductions of all expenses of the Fund such as
management fees), in the value of a hypothetical pre-existing account having a
balance of one share at the beginning of the period, and dividing the difference
by the value of the account at the beginning of the base period to obtain the
base period return, and then compounding the base period return by adding 1,
raising the sum to a power equal to 365 divided by 7, and subtracting 1 from the
result.

    The yields quoted in any advertisement or other communication should not be
considered a representation of the yields of the Fund in the future since the
yield is not fixed. Actual yields will depend not only on the type, quality and
maturities of the investments held by the Fund and changes in interest rates on
such investments, but also on changes in the Fund's expenses during the period.

    Yield information may be useful in reviewing the performance of the Fund and
for providing a basis for comparison with other investment alternatives.
However, unlike bank deposits or other investments which typically pay a fixed
yield for a stated period of time, the Fund's yield fluctuates.


    The Fund may also advertise the growth of hypothetical investments of
$10,000, $50,000 and $100,000 in shares of the Fund by adding the sum of all
distributions on 10,000, 50,000 or 100,000 shares of the Fund since inception to
$10,000, $50,000 and $100,000, as the case may be. Investments of $10,000,
$50,000 and $100,000 in the Fund at inception (February 17, 1982) would have
grown to $28,136, $140,680 and $281,360, respectively, at January 31, 2000.

Item 24.  PERSONS CONTROLLED BY OR UNDER COMMON CONTROL WITH THE FUND.

             None

Item 25.  INDEMNIFICATION.

     Pursuant to Section 5.3 of the Registrant's Declaration of Trust and under
Section 4.8 of the Registrant's By-Laws, the indemnification of the Registrant's
trustees, officers, employees and agents is permitted if it is determined that
they acted under the belief that their actions were in or not opposed to the
best interest of the Registrant, and, with respect to any criminal proceeding,
they had reasonable cause to believe their conduct was not unlawful. In
addition, indemnification is permitted only if it is determined that the actions
in question did not render them liable by reason of willful misfeasance, bad
faith or gross negligence in the performance of their duties or by reason of
reckless disregard of their obligations and duties to the Registrant. Trustees,
officers, employees and agents will be indemnified for the expense of litigation
if it is determined that they are entitled to indemnification against any
liability established in such litigation. The Registrant may also advance money
for these expenses provided that they give their undertakings to repay the
Registrant unless their conduct is later determined to permit indemnification.

     Pursuant to Section 5.2 of the Registrant's Declaration of Trust and
paragraph 8 of the Registrant's Investment Management Agreement, neither the
Investment Manager nor any trustee, officer, employee or agent of the Registrant
shall be liable for any action or failure to act, except in the case of bad
faith, willful misfeasance, gross negligence or reckless disregard of duties to
the Registrant.

          Insofar as indemnification for liabilities arising under the
Securities Act of 1933 (the "Act") may be permitted to trustees, officers and
controlling persons of the Registrant pursuant to the foregoing provisions or
otherwise, the Registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Act and is, therefore, unenforceable. In the event that a claim
for indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a trustee, officer, or controlling
person of the Registrant in connection with the successful defense of any
action, suit or proceeding) is asserted against the Registrant by such trustee,
officer or controlling person 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.

          The Registrant hereby undertakes that it will apply the
indemnification provision of its by-laws in a manner consistent with Release
11330 of the Securities and Exchange Commission under the Investment Company Act
of 1940, so long as the interpretation of Sections 17(h) and 17(i) of such Act
remains in effect.

          Registrant, in conjunction with the Investment Manager, Registrant's
Trustees, and other registered investment management companies managed by the
Investment Manager, maintains insurance on behalf of any person who is or was a
Trustee, officer, employee, or agent of Registrant, or who is or was serving at
the request of Registrant as a trustee, director, officer, employee or agent of
another trust or corporation, against any liability asserted against him and
incurred by him or arising out of his position. However, in no event will
Registrant


                                       3
<PAGE>

maintain insurance to indemnify any such person for any act for which Registrant
itself is not permitted to indemnify him.

                           MORGAN STANLEY DEAN WITTER
                       U.S. GOVERNMENT MONEY MARKET TRUST

                     AMENDED AND RESTATED AS OF MAY 1, 1999

                                    ARTICLE I

                                   DEFINITIONS

   The terms "COMMISSION," "DECLARATION," "DISTRIBUTOR," "INVESTMENT ADVISER,"
"MAJORITY SHAREHOLDER VOTE," "1940 ACT," "SHAREHOLDER," "SHARES," "TRANSFER
AGENT," "TRUST," "TRUST PROPERTY," and "TRUSTEES" have the respective meanings
given them in the Declaration of Trust of Morgan Stanley Dean Witter U.S.
Government Money Market Trust dated November 18, 1981, as amended from time to
time.

                                   ARTICLE II

                                     OFFICES

   SECTION 2.1. PRINCIPAL OFFICE. Until changed by the Trustees, the
principal office of the Trust in the Commonwealth of Massachusetts shall be
in the City of Boston, County of Suffolk.

   SECTION 2.2. OTHER OFFICES. In addition to its principal office in the
Commonwealth of Massachusetts, the Trust may have an office or offices in the
City of New York, State of New York, and at such other places within and without
the Commonwealth as the Trustees may from time to time designate or the business
of the Trust may require.

                                   ARTICLE III

                             SHAREHOLDERS' MEETINGS

   SECTION 3.1. PLACE OF MEETINGS. Meetings of Shareholders shall be held at
such place, within or without the Commonwealth of Massachusetts, as may be
designated from time to time by the Trustees.

   SECTION 3.2. MEETINGS. Meetings of Shareholders of the Trust shall be held
whenever called by the Trustees or the President of the Trust and whenever
election of a Trustee or Trustees by Shareholders is required by the provisions
of Section 16(a) of the 1940 Act, for that purpose. Meetings of Shareholders
shall also be called by the Secretary upon the written request of the holders of
Shares entitled to vote not less than twenty-five percent (25%) of all the votes
entitled to be cast at such meeting. Such request shall state the purpose or
purposes of such meeting and the matters proposed to be acted on thereat. The
Secretary shall inform such Shareholders of the reasonable estimated cost of
preparing and mailing such notice of the meeting, and upon payment to the Trust
of such costs, the Secretary shall give notice stating the purpose or purposes
of the meeting to all entitled to vote at such meeting. No meeting need be
called upon the request of the holders of Shares entitled to cast less than a
majority of all votes entitled to be cast at such meeting, to consider any
matter which is substantially the same as a matter voted upon at any meeting of
Shareholders held during the preceding twelve months.

   SECTION 3.3. NOTICE OF MEETINGS. Written or printed notice of every
Shareholders' meeting stating the place, date, and purpose or purposes thereof,
shall be given by the Secretary not less than ten (10) nor more than ninety (90)
days before such meeting to each Shareholder entitled to vote at such meeting.
Such notice shall be deemed to be given when deposited in the United States
mail, postage prepaid, directed to the Shareholder at his address as it appears
on the records of the Trust.

   SECTION 3.4. QUORUM AND ADJOURNMENT OF MEETINGS. Except as otherwise provided
by law, by the Declaration or by these By-Laws, at all meetings of Shareholders,
the holders of a majority of the Shares issued and outstanding and entitled to
vote thereat, present in person or represented by proxy, shall be


                                        1
<PAGE>

requisite and shall constitute a quorum for the transaction of business. In the
absence of a quorum, the Shareholders present or represented by proxy and
entitled to vote thereat shall have the power to adjourn the meeting from time
to time. The Shareholders present in person or represented by proxy at any
meeting and entitled to vote thereat also shall have the power to adjourn the
meeting from time to time if the vote required to approve or reject any proposal
described in the original notice of such meeting is not obtained (with proxies
being voted for or against adjournment consistent with the votes for and against
the proposal for which the required vote has not been obtained). The affirmative
vote of the holders of a majority of the Shares then present in person or
represented by proxy shall be required to adjourn any meeting. Any adjourned
meeting may be reconvened without further notice or change in record date. At
any reconvened meeting at which a quorum shall be present, any business may be
transacted that might have been transacted at the meeting as originally called.

   SECTION 3.5. VOTING RIGHTS, PROXIES. At each meeting of Shareholders, each
holder of record of Shares entitled to vote thereat shall be entitled to one
vote in person or by proxy for each Share of beneficial interest of the Trust
and for the fractional portion of one vote for each fractional Share entitled to
vote so registered in his or her name on the records of the Trust on the date
fixed as the record date for the determination of Shareholders entitled to vote
at such meeting. Without limiting the manner in which a Shareholder may
authorize another person or persons to act for such Shareholder as proxy
pursuant hereto, the following shall constitute a valid means by which a
Shareholder may grant such authority:

       (i) A Shareholder may execute a writing authorizing another person or
       persons to act for such Shareholder as proxy. Execution may be
       accomplished by the Shareholder or such Shareholder's authorized officer,
       director, employee, attorney-in-fact or another agent signing such
       writing or causing such person's signature to be affixed to such writing
       by any reasonable means including, but not limited to, by facsimile or
       telecopy signature. No written evidence of authority of a Shareholder's
       authorized officer, director, employee, attorney-in-fact or other agent
       shall be required; and

       (ii) A Shareholder may authorize another person or persons to act for
       such Shareholder as proxy by transmitting or authorizing the transmission
       of a telegram or cablegram or by other means of telephonic, electronic or
       computer transmission to the person who will be the holder of the proxy
       or to a proxy solicitation firm, proxy support service organization or
       like agent duly authorized by the person who will be the holder of the
       proxy to receive such transmission, provided that any such telegram or
       cablegram or other means of telephonic, electronic or computer
       transmission must either set forth or be submitted with information from
       which it can be determined that the telegram, cablegram or other
       transmission was authorized by the Shareholder.

No proxy shall be valid after eleven months from its date, unless otherwise
provided in the proxy. At all meetings of Shareholders, unless the voting is
conducted by inspectors, all questions relating to the qualification of voters
and the validity of proxies and the acceptance or rejection of votes shall be
decided by the chairman of the meeting. In determining whether a telegram,
cablegram or other electronic transmission is valid, the chairman or inspector,
as the case may be, shall specify the information upon which he or she relied.
Pursuant to a resolution of a majority of the Trustees, proxies may be solicited
in the name of one or more Trustees or Officers of the Trust. Proxy
solicitations may be made in writing or by using telephonic or other electronic
solicitation procedures that include appropriate methods of verifying the
identity of the Shareholder and confirming any instructions given thereby.

   SECTION 3.6. VOTE REQUIRED. Except as otherwise provided by law, by the
Declaration of Trust, or by these By-Laws, at each meeting of Shareholders at
which a quorum is present, all matters shall be decided by Majority Shareholder
Vote.

   SECTION 3.7. INSPECTORS OF ELECTION. In advance of any meeting of
Shareholders, the Trustees may appoint Inspectors of Election to act at the
meeting or any adjournment thereof. If Inspectors of Election are not so
appointed, the chairman of any meeting of Shareholders may, and on the request
of any Shareholder or his proxy shall, appoint Inspectors of Election of the
meeting. In case any person appointed as Inspector fails to appear or fails or
refuses to act, the vacancy may be filled by appointment made by the Trustees in
advance of the convening of the meeting or at the meeting by the person acting


                                        2
<PAGE>

as chairman. The Inspectors of Election shall determine the number of Shares
outstanding, the Shares represented at the meeting, the existence of a quorum,
the authenticity, validity and effect of proxies, shall receive votes, ballots
or consents, shall hear and determine all challenges and questions in any way
arising in connection with the right to vote, shall count and tabulate all votes
or consents, determine the results, and do such other acts as may be proper to
conduct the election or vote with fairness to all Shareholders. On request of
the chairman of the meeting, or of any Shareholder or his proxy, the Inspectors
of Election shall make a report in writing of any challenge or question or
matter determined by them and shall execute a certificate of any facts found by
them.

   SECTION 3.8. INSPECTION OF BOOKS AND RECORDS. Shareholders shall have such
rights and procedures of inspection of the books and records of the Trust as are
granted to Shareholders under Section 32 of the Business Corporation Law of the
Commonwealth of Massachusetts.

   SECTION 3.9. ACTION BY SHAREHOLDERS WITHOUT MEETING. Except as otherwise
provided by law, the provisions of these By-Laws relating to notices and
meetings to the contrary notwithstanding, any action required or permitted to be
taken at any meeting of Shareholders may be taken without a meeting if a
majority of the Shareholders entitled to vote upon the action consent to the
action in writing and such consents are filed with the records of the Trust.
Such consent shall be treated for all purposes as a vote taken at a meeting of
Shareholders.

   SECTION 3.10. PRESENCE AT MEETINGS. Presence at meetings of shareholders
requires physical attendance by the shareholder or his or her proxy at the
meeting site and does not encompass attendance by telephonic or other electronic
means.

                                   ARTICLE IV

                                    TRUSTEES

   SECTION 4.1. MEETINGS OF THE TRUSTEES. The Trustees may in their discretion
provide for regular or special meetings of the Trustees. Regular meetings of the
Trustees may be held at such time and place as shall be determined from time to
time by the Trustees without further notice. Special meetings of the Trustees
may be called at any time by the President and shall be called by the President
or the Secretary upon the written request of any two (2) Trustees.

   SECTION 4.2. NOTICE OF SPECIAL MEETINGS. Written notice of special meetings
of the Trustees, stating the place, date and time thereof, shall be given not
less than two (2) days before such meeting to each Trustee, personally, by
telegram, by mail, or by leaving such notice at his place of residence or usual
place of business. If mailed, such notice shall be deemed to be given when
deposited in the United States mail, postage prepaid, directed to the Trustee at
his address as it appears on the records of the Trust. Subject to the provisions
of the 1940 Act, notice or waiver of notice need not specify the purpose of any
special meeting.

   SECTION 4.3. TELEPHONE MEETINGS. Subject to the provisions of the 1940 Act,
any Trustee, or any member or members of any committee designated by the
Trustees, may participate in a meeting of the Trustees, or any such committee,
as the case may be, by means of a conference telephone or similar communications
equipment if all persons participating in the meeting can hear each other at the
same time. Participation in a meeting by these means constitutes presence in
person at the meeting.

   SECTION 4.4. QUORUM, VOTING AND ADJOURNMENT OF MEETINGS. At all meetings of
the Trustees, a majority of the Trustees shall be requisite to and shall
constitute a quorum for the transaction of business. If a quorum is present, the
affirmative vote of a majority of the Trustees present shall be the act of the
Trustees, unless the concurrence of a greater proportion is expressly required
for such action by law, the Declaration or these By-Laws. If at any meeting of
the Trustees there be less than a quorum present, the Trustees present thereat
may adjourn the meeting from time to time, without notice other than
announcement at the meeting, until a quorum shall have been obtained.

   SECTION 4.5. ACTION BY TRUSTEES WITHOUT MEETING. The provisions of these
By-Laws covering notices and meetings to the contrary notwithstanding, and
except as required by law, any action required or permitted to be taken at any
meeting of the Trustees may be taken without a meeting if a consent in


                                        3
<PAGE>

writing setting forth the action shall be signed by all of the Trustees entitled
to vote upon the action and such written consent is filed with the minutes of
proceedings of the Trustees.

   SECTION 4.6. EXPENSES AND FEES. Each Trustee may be allowed expenses, if any,
for attendance at each regular or special meeting of the Trustees, and each
Trustee who is not an officer or employee of the Trust or of its investment
manager or underwriter or of any corporate affiliate of any of said persons
shall receive for services rendered as a Trustee of the Trust such compensation
as may be fixed by the Trustees. Nothing herein contained shall be construed to
preclude any Trustee from serving the Trust in any other capacity and receiving
compensation therefor.

   SECTION 4.7. EXECUTION OF INSTRUMENTS AND DOCUMENTS AND SIGNING OF CHECKS AND
OTHER OBLIGATIONS AND TRANSFERS. All instruments, documents and other papers
shall be executed in the name and on behalf of the Trust and all checks, notes,
drafts and other obligations for the payment of money by the Trust shall be
signed, and all transfer of securities standing in the name of the Trust shall
be executed, by the Chairman, the President, any Vice President or the Treasurer
or by any one or more officers or agents of the Trust as shall be designated for
that purpose by vote of the Trustees; notwithstanding the above, nothing in this
Section 4.7 shall be deemed to preclude the electronic authorization, by
designated persons, of the Trust's Custodian (as described herein in Section
9.1) to transfer assets of the Trust, as provided for herein in Section 9.1.

   SECTION 4.8. INDEMNIFICATION OF TRUSTEES, OFFICERS, EMPLOYEES AND AGENTS. (a)
The Trust shall indemnify any person who was or is a party or is threatened to
be made a party to any threatened, pending, or completed action, suit or
proceeding, whether civil, criminal, administrative or investigative (other than
an action by or in the right of the Trust) by reason of the fact that he is or
was a Trustee, officer, employee, or agent of the Trust. The indemnification
shall be against expenses, including attorneys' fees, judgments, fines, and
amounts paid in settlement, actually and reasonably incurred by him in
connection with the action, suit, or proceeding, if he acted in good faith and
in a manner he reasonably believed to be in or not opposed to the best interests
of the Trust, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. The termination of any
action, suit or proceeding by judgment, order, settlement, conviction, or upon a
plea of nolo contendere or its equivalent, shall not, of itself, create a
presumption that the person did not act in good faith and in a manner which he
reasonably believed to be in or not opposed to the best interests of the Trust,
and, with respect to any criminal action or proceeding, had reasonable cause to
believe that his conduct was unlawful.

   (b) The Trust shall indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action or
suit by or on behalf of the Trust to obtain a judgment or decree in its favor by
reason of the fact that he is or was a Trustee, officer, employee, or agent of
the Trust. The indemnification shall be against expenses, including attorneys'
fees actually and reasonably incurred by him in connection with the defense or
settlement of the action or suit, if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the Trust;
except that no indemnification shall be made in respect of any claim, issue, or
matter as to which the person has been adjudged to be liable for negligence or
misconduct in the performance of his duty to the Trust, except to the extent
that the court in which the action or suit was brought, or a court of equity in
the county in which the Trust has its principal office, determines upon
application that, despite the adjudication of liability but in view of all
circumstances of the case, the person is fairly and reasonably entitled to
indemnity for those expenses which the court shall deem proper, provided such
Trustee, officer, employee or agent is not adjudged to be liable by reason of
his willful misfeasance, bad faith, gross negligence or reckless disregard of
the duties involved in the conduct of his office.

   (c) To the extent that a Trustee, officer, employee, or agent of the Trust
has been successful on the merits or otherwise in defense of any action, suit or
proceeding referred to in subsection (a) or (b) or in defense of any claim,
issue or matter therein, he shall be indemnified against expenses, including
attorneys' fees, actually and reasonably incurred by him in connection
therewith.

   (d) (1) Unless a court orders otherwise, any indemnification under
subsections (a) or (b) of this section may be made by the Trust only as
authorized in the specific case after a determination that indemnification of
the Trustee, officer, employee, or agent is proper in the circumstances because
he has met the applicable standard of conduct set forth in subsections (a) or
(b).


                                        4
<PAGE>

       (2) The determination shall be made:

       (i) By the Trustees, by a majority vote of a quorum which consists of
    Trustees who were not parties to the action, suit or proceeding; or

      (ii) If the required quorum is not obtainable, or if a quorum of
    disinterested Trustees so directs, by independent legal counsel in a written
    opinion; or

     (iii) By the Shareholders.

     (3) Notwithstanding any provision of this Section 4.8, no person shall be
    entitled to indemnification for any liability, whether or not there is an
    adjudication of liability, arising by reason of willful misfeasance, bad
    faith, gross negligence, or reckless disregard of duties as described in
    Section 17(h) and (i) of the Investment Company Act of 1940 ("disabling
    conduct"). A person shall be deemed not liable by reason of disabling
    conduct if, either:

       (i) a final decision on the merits is made by a court or other body
    before whom the proceeding was brought that the person to be indemnified
    ("indemnitee") was not liable by reason of disabling conduct; or

      (ii) in the absence of such a decision, a reasonable determination, based
    upon a review of the facts, that the indemnitee was not liable by reason of
    disabling conduct, is made by either--

          (A) a majority of a quorum of Trustees who are neither "interested
         persons" of the Trust, as defined in Section 2(a)(19) of the Investment
         Company Act of 1940, nor parties to the action, suit or proceeding, or

          (B) an independent legal counsel in a written opinion.

   (e) Expenses, including attorneys' fees, incurred by a Trustee, officer,
employee or agent of the Trust in defending a civil or criminal action, suit or
proceeding may be paid by the Trust in advance of the final disposition thereof
if:

        (1) authorized in the specific case by the Trustees; and

        (2) the Trust receives an undertaking by or on behalf of the Trustee,
    officer, employee or agent of the Trust to repay the advance if it is not
    ultimately determined that such person is entitled to be indemnified by the
    Trust; and

        (3) either, (i) such person provides a security for his undertaking, or

           (ii) the Trust is insured against losses by reason of any lawful
         advances, or

          (iii) a determination, based on a review of readily available facts,
         that there is reason to believe that such person ultimately will be
         found entitled to indemnification, is made by either--

              (A) a majority of a quorum which consists of Trustees who are
             neither "interested persons" of the Trust, as defined in Section
             2(a)(19) of the 1940 Act, nor parties to the action, suit or
             proceeding, or

              (B) an independent legal counsel in a written opinion.

   (f) The indemnification provided by this Section shall not be deemed
exclusive of any other rights to which a person may be entitled under any
by-law, agreement, vote of Shareholders or disinterested Trustees or otherwise,
both as to action in his official capacity and as to action in another capacity
while holding the office, and shall continue as to a person who has ceased to be
a Trustee, officer, employee, or agent and inure to the benefit of the heirs,
executors and administrators of such person; provided that no person may satisfy
any right of indemnity or reimbursement granted herein or to which he may be
otherwise entitled except out of the property of the Trust, and no Shareholder
shall be personally liable with respect to any claim for indemnity or
reimbursement or otherwise.


                                        5

   (g) The Trust may purchase and maintain insurance on behalf of any person who
is or was a Trustee, officer, employee, or agent of the Trust, against any
liability asserted against him and incurred by him in any such capacity, or
arising out of his status as such. However, in no event will the Trust purchase
insurance to indemnify any officer or Trustee against liability for any act for
which the Trust itself is not permitted to indemnify him.

   (h) Nothing contained in this Section shall be construed to protect any
Trustee or officer of the Trust against any liability to the Trust or to its
security holders to which he would otherwise be subject by reason of willful
misfeasance, bad faith, gross negligence or reckless disregard of the duties
involved in the conduct of his office.

                                    ARTICLE V

                                   COMMITTEES

   SECTION 5.1. EXECUTIVE AND OTHER COMMITTEES. The Trustees, by resolution
adopted by a majority of the Trustees, may designate an Executive Committee
and/or committees, each committee to consist of two (2) or more of the Trustees
of the Trust and may delegate to such committees, in the intervals between
meetings of the Trustees, any or all of the powers of the Trustees in the
management of the business and affairs of the Trust. In the absence of any
member of any such committee, the members thereof present at any meeting,
whether or not they constitute a quorum, may appoint a Trustee to act in place
of such absent member. Each such committee shall keep a record of its
proceedings.

   The Executive Committee and any other committee shall fix its own rules or
procedure, but the presence of at least fifty percent (50%) of the members of
the whole committee shall in each case be necessary to constitute a quorum of
the committee and the affirmative vote of the majority of the members of the
committee present at the meeting shall be necessary to take action.

   All actions of the Executive Committee shall be reported to the Trustees at
the meeting thereof next succeeding to the taking of such action.

   SECTION 5.2. ADVISORY COMMITTEE. The Trustees may appoint an advisory
committee which shall be composed of persons who do not serve the Trust in any
other capacity and which shall have advisory functions with respect to the
investments of the Trust but which shall have no power to determine that any
security or other investment shall be purchased, sold or otherwise disposed of
by the Trust. The number of persons constituting any such advisory committee
shall be determined from time to time by the Trustees. The members of any such
advisory committee may receive compensation for their services and may be
allowed such fees and expenses for the attendance at meetings as the Trustees
may from time to time determine to be appropriate.

   SECTION 5.3. COMMITTEE ACTION WITHOUT MEETING. The provisions of these
By-Laws covering notices and meetings to the contrary notwithstanding, and
except as required by law, any action required or permitted to be taken at any
meeting of any Committee of the Trustees appointed pursuant to Section 5.1 of
these By-Laws may be taken without a meeting if a consent in writing setting
forth the action shall be signed by all members of the Committee entitled to
vote upon the action and such written consent is filed with the records of the
proceedings of the Committee.

                                   ARTICLE VI

   SECTION 6.1. EXECUTIVE OFFICERS. The executive officers of the Trust shall be
a Chairman, a President, one or more Vice Presidents, a Secretary and a
Treasurer. The Chairman shall be selected from among the Trustees but none of
the other executive officers need be a Trustee. Two or more offices, except
those of President and any Vice President, may be held by the same person, but
no officer shall execute, acknowledge or verify any instrument in more than one
capacity. The executive officers of the Trust shall be elected annually by the
Trustees and each executive officer so elected shall hold office until his or
her successor is elected and has qualified.

person so removed.

more Vice Presidents such of his or her powers and duties at such times and in
such manner as he or she may deem advisable.

   SECTION 6.8. THE VICE PRESIDENTS. The Vice Presidents shall be of such number
and shall have such titles as may be determined from time to time by the
Trustees. The Vice President, or, if there shall be more than one, the Vice

or the Chairman, shall, in the absence or disability of the President, exercise
the powers and perform the duties of the President, and shall perform such other

   SECTION 6.10. THE SECRETARY. The Secretary shall attend all meetings of the
Trustees and all meetings of the Shareholders and record all the proceedings of

to time prescribe. He or she shall keep in safe custody the seal of the Trust

signature of an Assistant Secretary.

   SECTION 6.11. THE ASSISTANT SECRETARIES. The Assistant Secretary, or, if

officer of the Trust. He or she shall keep or cause to be kept full and accurate
accounts of receipts and disbursements in books belonging to the Trust, and he

                                   ARTICLE VII

                           DIVIDENDS AND DISTRIBUTIONS

   Subject to any applicable provisions of law and the Declaration, dividends
and distributions upon the Shares may be declared at such intervals as the
Trustees may determine, in cash, in securities or other property, or in Shares,
from any sources permitted by law, all as the Trustees shall from time to time
determine.

   Inasmuch as the computation of net income and net profits from the sales of
securities or other properties for federal income tax purposes may vary from the
computation thereof on the records of the Trust, the Trustees shall have power,
in their discretion, to distribute as income dividends and as capital gain
distributions, respectively, amounts sufficient to enable the Trust to avoid or
reduce liability for federal income taxes.

                                  ARTICLE VIII

                             CERTIFICATES OF SHARES

   SECTION 8.1. CERTIFICATES OF SHARES. Certificates for Shares of each series
or class of Shares shall be in such form and of such design as the Trustees
shall approve, subject to the right of the Trustees to change such form and
design at any time or from time to time, and shall be entered in the records of
the Trust as they are issued. Each such certificate shall bear a distinguishing
number; shall exhibit the holder's name and certify the number of full Shares
owned by such holder; shall be signed by or in the name of the Trust by the
President, or a Vice President, and countersigned by the Secretary or an
Assistant Secretary or the Treasurer and an Assistant Treasurer of the Trust;
shall be sealed with the seal; and shall contain such recitals as may be
required by law. Where any certificate is signed by a Transfer Agent or by a
Registrar, the signature of such officers and the seal may be facsimile, printed
or engraved. The Trust may, at its option, determine not to issue a certificate
or certificates to evidence Shares owned of record by any Shareholder.

   In case any officer or officers who shall have signed, or whose facsimile
signature or signatures shall appear on, any such certificate or certificates
shall cease to be such officer or officers of the Trust, whether because of
death, resignation or otherwise, before such certificate or certificates shall
have been delivered by the Trust, such certificate or certificates shall,
nevertheless, be adopted by the Trust and be issued and delivered as though the
person or persons who signed such certificate or certificates or whose facsimile
signature or signatures shall appear therein had not ceased to be such officer
or officers of the Trust.

   No certificate shall be issued for any share until such share is fully paid.

   SECTION 8.2. LOST, STOLEN, DESTROYED AND MUTILATED CERTIFICATES. The
Trustees may direct a new certificate or certificates to be issued in place
of any certificate or certificates theretofore issued by the


                                        8
<PAGE>

Trust alleged to have been lost, stolen or destroyed, upon satisfactory proof of
such loss, theft, or destruction; and the Trustees may, in their discretion,
require the owner of the lost, stolen or destroyed certificate, or his legal
representative, to give to the Trust and to such Registrar, Transfer Agent
and/or Transfer Clerk as may be authorized or required to countersign such new
certificate or certificates, a bond in such sum and of such type as they may
direct, and with such surety or sureties, as they may direct, as indemnity
against any claim that may be against them or any of them on account of or in
connection with the alleged loss, theft or destruction of any such certificate.

                                   ARTICLE IX

                                    CUSTODIAN

   SECTION 9.1. APPOINTMENT AND DUTIES. The Trust shall at times employ a bank
or trust company having capital, surplus and undivided profits of at least five
million dollars ($5,000,000) as custodian with authority as its agent, but
subject to such restrictions, limitations and other requirements, if any, as may
be contained in these By-Laws and the 1940 Act:

     (1) to receive and hold the securities owned by the Trust and deliver the
    same upon written or electronically transmitted order;

     (2) to receive and receipt for any moneys due to the Trust and deposit the
    same in its own banking department or elsewhere as the Trustees may direct;

     (3) to disburse such funds upon orders or vouchers;

all upon such basis of compensation as may be agreed upon between the Trustees
and the custodian. If so directed by a Majority Shareholder Vote, the custodian
shall deliver and pay over all property of the Trust held by it as specified in
such vote.

   The Trustees may also authorize the custodian to employ one or more
sub-custodians from time to time to perform such of the acts and services of the
custodian and upon such terms and conditions as may be agreed upon between the
custodian and such sub-custodian and approved by the Trustees provided that in
every case such sub-custodian shall be a bank or trust company organized under
the laws of the United States or one of the states thereof and having capital,
surplus and undivided profits of at least five million dollars ($5,000,000).

   SECTION 9.2. CENTRAL CERTIFICATE SYSTEM. Subject to such rules, regulations
and orders as the Commission may adopt, the Trustees may direct the custodian to
deposit all or any part of the securities owned by the Trust in a system for the
central handling of securities established by a national securities exchange or
a national securities association registered with the Commission under the
Securities Exchange Act of 1934, or such other person as may be permitted by the
Commission, or otherwise in accordance with the 1940 Act, pursuant to which
system all securities of any particular class or series of any issuer deposited
within the system are treated as fungible and may be transferred or pledged by
bookkeeping entry without physical delivery of such securities, provided that
all such deposits shall be subject to withdrawal only upon the order of the
Trust.

                                    ARTICLE X

                                WAIVER OF NOTICE

   Whenever any notice of the time, place or purpose of any meeting of
Shareholders, Trustees, or of any committee is required to be given in
accordance with law or under the provisions of the Declaration or these By-Laws,
a waiver thereof in writing, signed by the person or persons entitled to such
notice and filed with the records of the meeting, whether before or after the
holding thereof, or actual attendance at the meeting of shareholders, Trustees
or committee, as the case may be, in person, shall be deemed equivalent to the
giving of such notice to such person.

                                   ARTICLE XI

                                  MISCELLANEOUS

   SECTION 11.1. LOCATION OF BOOKS AND RECORDS. The books and records of the
Trust may be kept outside the Commonwealth of Massachusetts at such place or
places as the Trustees may from time to time determine, except as otherwise
required by law.


                                        9
<PAGE>

   SECTION 11.2. RECORD DATE. The Trustees may fix in advance a date as the
record date for the purpose of determining the Shareholders entitled to (i)
receive notice of, or to vote at, any meeting of Shareholders, or (ii) receive
payment of any dividend or the allotment of any rights, or in order to make a
determination of Shareholders for any other proper purpose. The record date, in
any case, shall not be more than one hundred eighty (180) days, and in the case
of a meeting of Shareholders not less than ten (10) days, prior to the date on
which such meeting is to be held or the date on which such other particular
action requiring determination of Shareholders is to be taken, as the case may
be. In the case of a meeting of Shareholders, the meeting date set forth in the
notice to Shareholders accompanying the proxy statement shall be the date used
for purposes of calculating the 180 day or 10 day period, and any adjourned
meeting may be reconvened without a change in record date. In lieu of fixing a
record date, the Trustees may provide that the transfer books shall be closed
for a stated period but not to exceed, in any case, twenty (20) days. If the
transfer books are closed for the purpose of determining Shareholders entitled
to notice of a vote at a meeting of Shareholders, such books shall be closed for
at least ten (10) days immediately preceding the meeting.

   SECTION 11.3. SEAL. The Trustees shall adopt a seal, which shall be in such
form and shall have such inscription thereon as the Trustees may from time to
time provide. The seal of the Trust may be affixed to any document, and the seal
and its attestation may be lithographed, engraved or otherwise printed on any
document with the same force and effect as if it had been imprinted and attested
manually in the same manner and with the same effect as if done by a
Massachusetts business corporation under Massachusetts law.

   SECTION 11.4. FISCAL YEAR. The fiscal year of the Trust shall end on such
date as the Trustees may by resolution specify, and the Trustees may by
resolution change such date for future fiscal years at any time and from time to
time.

   SECTION 11.5. ORDERS FOR PAYMENT OF MONEY. All orders or instructions for the
payment of money of the Trust, and all notes or other evidences of indebtedness
issued in the name of the Trust, shall be signed by such officer or officers or
such other person or persons as the Trustees may from time to time designate, or
as may be specified in or pursuant to the agreement between the Trust and the
bank or trust company appointed as Custodian of the securities and funds of the
Trust.

                                   ARTICLE XII

                       COMPLIANCE WITH FEDERAL REGULATIONS

   The Trustees are hereby empowered to take such action as they may deem to be
necessary, desirable or appropriate so that the Trust is or shall be in
compliance with any federal or state statute, rule or regulation with which
compliance by the Trust is required.

                                  ARTICLE XIII

                                   AMENDMENTS

   These By-Laws may be amended, altered, or repealed, or new By-Laws may be
adopted, (a) by a Majority Shareholder Vote, or (b) by the Trustees; provided,
however, that no By-Law may be amended, adopted or repealed by the Trustees if
such amendment, adoption or repeal requires, pursuant to law, the Declaration,
or these By-Laws, a vote of the Shareholders. The Trustees shall in no event
adopt By-Laws which are in conflict with the Declaration, and any apparent
inconsistency shall be construed in favor of the related provisions in the
Declaration.

                                   ARTICLE XIV

                              DECLARATION OF TRUST

   The Declaration of Trust establishing Morgan Stanley Dean Witter U.S.
Government Money Market Trust, dated November 18, 1981, a copy of which,
together with all amendments thereto, is on file in the office of the Secretary
of the Commonwealth of Massachusetts, provides that the name Morgan Stanley


                                       10
<PAGE>

Dean Witter U.S. Government Money Market Trust refers to the Trustees under the
Declaration collectively as Trustees, but not as individuals or personally; and
no Trustee, Shareholder, officer, employee or agent of Morgan Stanley Dean
Witter U.S. Government Money Market Trust shall be held to any personal
liability, nor shall resort be had to their private property for the
satisfaction of any obligation or claim or otherwise, in connection with the
affairs of said Morgan Stanley Dean Witter U.S. Government Money Market Trust,

                     Re: REGISTRATION STATEMENT ON FORM N-1

Gentlemen:

          At your request we have examined the Registration Statement on Form
N-1 (the "Registration Statement") which you have filed with the Securities and
Exchange Commission in connection with the registration under the Securities Act
of 1933, as amended, of an unlimited number of Shares of Beneficial Interest
(the "Shares") of the Sears U.S. Government Money Market Trust (the "Trust"). We
are familiar with the proceedings taken by you in connection with the
authorization, issuance and sale of the Shares. Additionally, we have examined
such documents and such questions of law and fact as we have considered
necessary or appropriate for purposes of this opinion. As to matters of
Massachusetts law, we have relied upon the opinion of Gaston Snow & Ely
Bartlett.

          Based upon the foregoing, we are of the opinion that, subject to the
proceedings contemplated above being duly taken and completed by you, upon the
effective date of the Registration Statement, the Shares to be issued by you
pursuant to the Registration Statement, when issued from time to time in
accordance with the Trust's Declaration of Trust, will be legally and validly
issued, fully paid and nonassessable by the Trust.

          We consent to your filing this opinion as an exhibit to the
Registration Statement and to the reference to our firm in the prospectus
included therein.

                                                  Very truly yours,

                                                  /s/ Latham, Watkins, & Hills

       Dean Witter Fund shareholders and other MSDW Advisors clients, and be
       certain that at all times the interests of the shareholders and other
       clients are placed ahead of any personal interest.

    B.  AVOID ACTUAL AND POTENTIAL CONFLICTS OF INTEREST

        The restrictions and requirements of this Code of Ethics are designed to
        prevent behavior which conflicts, potentially conflicts or raises the
        appearance of actual or potential conflict with the interests of the
        shareholders of the Morgan Stanley Dean Witter Funds and MSDW Advisors
        Managed Account clients. It is of the utmost importance that the
        personal securities transactions of employees and affiliates be
        conducted in a manner consistent with both the letter and spirit of this
        Code of Ethics, including these principles. Only then can an individual,
        and MSDW Advisors, Services and Distributors as a whole, be certain to
        avoid any actual or potential conflict of interest or any abuse of an
        individual's position of trust and responsibility.

    C.  AVOID UNDUE PERSONAL BENEFIT

        MSDW Advisors, Services and Distributors employees and affiliates should
        ensure that they do not acquire undue personal benefit or advantage as a
        result of the performance of their normal duties as they relate to the
        Morgan Stanley Dean Witter Funds and other MSDW Advisors clients.
        Consistent with the first principle that the interests of the Morgan
        Stanley Dean Witter Fund shareholders and other MSDW Advisors clients
        must always come first is the fundamental standard that undue personal
        advantage deriving from the management by MSDW Advisors of other
        people's money is to be avoided.

III. OBJECTIVE

     The Securities and Exchange Commission's code of ethics rule contained in
     the Investment Company Act of 1940 makes it unlawful for certain persons
     associated with investment advisers or principal underwriters of investment
     companies to engage in conduct which is deceitful, fraudulent, or
     manipulative, or which involves false or misleading statements, in
     connection with the purchase or sale of a security held or proposed to be
     acquired by an investment company. In addition, Section 204A of the
     Investment Advisers Act of 1940 requires investment advisers to establish,
     maintain and enforce written policies and procedures designed to prevent
     misuse of material non-public information. The objective of this Code is to
     maintain the behavior of certain individuals associated with MSDW Advisors,
     Services and Distributors (herein called "Access Persons") within the
     general principles set forth above, as well as to prevent such persons from
     engaging in conduct proscribed by the code of ethics rule and Section 204A
     of the Investment Advisers Act. The Compliance Officer or Compliance
     Coordinator in MSDW Advisors Risk Management Department will identify all
     Access Persons and notify them of their reporting obligations at the time
     they become an Access Person. Access Persons include all directors,
     officers and employees of MSDW Advisors, Services or Distributors except
     those directors and officers of Distributors who meet the following three
     criteria: (i) they do not devote substantially all working time to the
     activities of MSDW Advisors, Services or Distributors; (ii) they do not, in
     connection with their regular functions and duties, participate in, obtain
     information with respect to, or make recommendations as to, the purchase
     and sale of securities; and (iii) they do not have access to information
     regarding the day-to-day investment activities of MSDW Advisors, Services
     or Distributors (those Directors and officers must, however, file quarterly
     transaction reports pursuant to Section V., sub-section D., below). An
     Officer or employee of MSDW Advisors, Distributors or Services on leave is
     not considered an Access Person hereunder, provided that during the period
     such person is on leave, subparagraphs (ii) and (iii) in the preceding
     sentence are applicable.

IV. GROUNDS FOR DISQUALIFICATION FROM EMPLOYMENT

    Pursuant to the terms of Section 9 of the Investment Company Act of 1940, no
    director, officer or employee of MSDW Advisors, Services or Distributors may
    become, or continue to remain, an officer, director or employee, without an
    exemptive order issued by the Securities and Exchange Commission, if such
    director, officer or employee is, or becomes:

    A. within the past ten years convicted of any felony or misdemeanor
       involving the purchase or sale of any security or arising out of the
       officer's or employee's conduct as an affiliated person, salesman or
       employee of any investment company, bank, insurance company or entity or
       person required to be registered under the Commodity Exchange Act; or

    B.  permanently or temporarily enjoined by any court from acting as an
       affiliated person, salesman or employee of any investment company, bank,
       insurance company or entity or person required to be registered under the
       Commodity Exchange Act, or from engaging in or continuing any conduct or
       practice in connection with any such activity or in connection with the
       purchase or sale of any security.

                                       2
<PAGE>
    It is your obligation to immediately report any conviction or injunction to
    the General Counsel of MSDW Advisors.

V.  PERSONAL TRANSACTIONS IN SECURITIES

    A. PROHIBITED CONDUCT

       No Access Person shall buy or sell any security for his own account or
       for an account in which he has, or as a result of the transaction
       acquires, any direct or indirect beneficial ownership (referred to herein
       as a "personal transaction") unless:

       1.  advance clearance of the transaction has been obtained; and

       2.  the transaction is reported in writing to MSDW Advisors in accordance
           with the requirements of sub-section D below.

    B.  RESTRICTIONS AND LIMITATIONS ON PERSONAL SECURITIES TRANSACTIONS

        The following restrictions and limitations govern investments and
        personal securities transactions by Access Persons. Unless otherwise
        indicated, all restrictions and limitations are applicable to all Access
        Persons:

       1.  Securities purchased may not be sold at a profit until at least 60
           days from the purchase trade date. In addition, securities sold may
           not be purchased at a lower price until at least 60 days from the
           sale trade date. Any violation will result in disgorgement of all
           profits from the transactions.

       2.  No short sales are permitted.

       3.  No transactions in options or futures are permitted.

       4.  No Access Person may acquire any security in an Initial Public
           Offering (IPO).

       5a. Private placements of any kind may only be acquired with special
           permission of the Code of Ethics Review Committee, and, if approved,
           will be subject to continuous monitoring for possible future
           conflict. Any Access Person wishing to request approval for private
           placements must complete an MSDW Advisors Private Placement Approval
           Request Form and submit the form to MSDW Advisors' Risk Management
           Department. A copy of MSDW Advisors Private Placement Approval
           Request Form, which may be revised at any time, is attached as
           Exhibit A. Where the Code of Ethics Review Committee approves any
           acquisition of private placements, its decision and reasons for
           supporting the decision will be documented in a written report, which
           is to be kept for five years in MSDW Advisors' Risk Management
           Department after the end of the fiscal year in which the approval was
           granted.

       5b. Any Access Person who has a personal position in an issuer through a
           private placement must affirmatively disclose that interest if such
           Access Person is involved in consideration of any subsequent
           investment decision regarding any security of that issuer or an
           affiliate by any Morgan Stanley Dean Witter Fund or MSDW Advisors
           Managed Account. In such event, the final investment decision shall
           be independently reviewed by MSDW Advisor's Chief Investment Officer.
           Written records of any such circumstance shall be maintained and sent
           to the MSDW Advisors' Risk Management Department.

       6.  Access Persons with MSDW Online accounts are permitted to trade ONLY
           between the hours of 9:30 a.m. and 4:00 p.m. (New York time). Trading
           after hours is prohibited.

       THE FOLLOWING RESTRICTIONS, 7a, 7b AND 7c, APPLY ONLY TO (I) PORTFOLIO
       MANAGERS (AND ALL PERSONS REPORTING TO PORTFOLIO MANAGERS) AND
       (II) PERSONNEL IN THE MSDW ADVISORS TRADING DEPARTMENT.

                                       3
<PAGE>
       7a. No purchase or sale transactions may be made in any security by any
           portfolio manager (or person reporting to a portfolio manager) for a
           period of thirty (30) days before or after that security is bought or
           sold by any Morgan Stanley Dean Witter Fund (other than Morgan
           Stanley Dean Witter Value-Added Market Series, Morgan Stanley Dean
           Witter Select Dimensions Investment Series--Value-Added Portfolio,
           Morgan Stanley Dean Witter Index Funds, or Portfolios) or MSDW
           Advisors Managed Account for which such portfolio manager (or the
           portfolio manager to whom such person reports) serves in that
           capacity.

       7b. No purchase or sale transactions may be made in any security traded
           through the MSDW Advisors trading department by any person employed
           in the MSDW Advisors trading department for a period of thirty (30)
           days before or after that security is bought or sold by any Morgan
           Stanley Dean Witter Fund (other than Morgan Stanley Dean Witter
           Value-Added Market Series, Morgan Stanley Dean Witter Select
           Dimensions Investment Series--Value-Added Portfolio, Morgan Stanley
           Dean Witter Index Funds, or Portfolios) or MSDW Advisors Managed
           Account.

       7c. Any transactions by persons described in (a) and (b) above within
           such enumerated period will be required to be reversed, if
           applicable, and any profits or, at the discretion of the Code of
           Ethics Review Committee, any differential between the sale price of
           the individual security transaction and the subsequent purchase or
           sale price by a relevant MSDW Fund during the enumerated period, will
           be subject to disgorgement.

           IMPORTANT: Regardless of the limited applicability of Restriction 7,
           MSDW Advisors' Risk Management Department monitors all transactions
           by ALL Access Persons in order to ascertain any pattern of conduct
           which may evidence conflicts or potential conflicts with the
           principles and objectives of this Code, including a pattern of
           frontrunning. On a quarterly basis, MSDW Advisors' Risk Management
           Department will provide the MSDW Funds Boards of Directors with a
           written report that (i) describes issues that arose during the
           previous quarter under this Code and if applicable, each MSDW Funds'
           Sub-Adviser's Code, including but not limited to, information about
           material violations and sanctions imposed in response to the material
           violations, and (ii) certifies that MSDW Advisors has adopted
           procedures reasonably necessary to prevent Access Persons from
           violating this Code.

    C.  ADVANCE CLEARANCE REQUIREMENT

       1.  PROCEDURES

           (a) FROM WHOM OBTAINED

               Subject to the limitations and restrictions of B above, advance
               clearance of a personal transaction in a security must be
               obtained from any two of the following officers of MSDW Advisors:

               (1) CEO/President

               (2) Chief Investment Officer

               (3) Chief Administrative Officer

               (4) General Counsel

               (5) any other person so designated by the CEO or President,
                   provided, however, that no more than ten persons, at any
                   time, may be Clearing Officers.

               These officers are referred to in this Code as "Clearing
               Officers."

                                       4
<PAGE>
               Prior to obtaining the two signatures from the Clearing Officers,
               the form must be approved by the MSDW Advisors Department
               responsible for the type of security for which permission is
               being sought, as follows:

<TABLE>
<S>                                            <C>
                1. Equity Trading              --Equity Trading Department
                2. Fixed-Income Corporate      --Manager,Corporate Fixed-Income
                  Bonds
                3. Municipal Bonds             --Manager, Municipal Fixed-Income
                4. Non-Investment Grade        --Manager, High Yield Fixed-Income
                  ("Junk") Bonds
                5. Collateralized Mortgage     --Manager, Government Fixed-Income
                  Obligations (CMOs) and
                  other non-exempt Mortgage
                  and Asset-Backed Securities
                6. Convertible Securities      --Manager, Convertible Securities
</TABLE>

               Prior to obtaining the Clearing Officers' signatures the form
               also must be reviewed and initialed by the MSDW Advisors' Risk
               Management Department. A copy of MSDW Advisors Securities
               Transaction Approval Form, which may be revised at any time, is
               attached as Exhibit B.

               The Clearing Officers will not sign unless the approvals of the
               relevant investment department and MSDW Advisors' Risk Management
               Department are indicated on the form. MSDW Advisors' Risk
               Management Department has implemented procedures reasonably
               designed to monitor purchases and sales effected pursuant to the
               aforementioned pre-clearance procedures.

           (b) TIME OF CLEARANCE

               All approved securities transactions, whether executed through A
               MSDW BROKERAGE ACCOUNT OR AN MSDW ONLINE ACCOUNT, must take
               place, prior to 4:00 p.m. EST, on the same day that the complete
               advance clearance is obtained. If the transaction is not
               completed on the date of clearance, a new clearance must be
               obtained, including one for any uncompleted portion.
               Post-approval is NOT PERMITTED under the Code of Ethics. If it is
               determined that a trade was completed before approval, it will be
               considered a violation of the Code of Ethics.

           (c) PERMITTED BROKERAGE ACCOUNTS

               ALL SECURITIES TRANSACTIONS MUST BE THROUGH AN MSDW BROKERAGE
               ACCOUNT OR AN MSDW ONLINE ACCOUNT; NO OTHER BROKERAGE ACCOUNTS
               ARE PERMITTED UNLESS SPECIAL PERMISSION IS OBTAINED. If you
               maintain accounts outside of MSDW, you must immediately transfer
               your accounts to a MSDW branch. Failure to do so will be
               considered a significant violation of the Code of Ethics. In the
               event permission is granted to maintain an outside brokerage
               account, it is the responsibility of the employee to arrange for
               duplicate confirmations of all securities transactions and
               monthly brokerage statements to be sent to the MSDW Advisors'
               Risk Management Department.

               Prior to opening an MSDW ONLINE ACCOUNT, Access Persons must
               obtain approval from MSDW Advisors' Risk Management Department.
               NO employee may open an MSDW Online account unless a completed
               and signed copy of their MSDW Online account application and MSDW
               Employee Account Request Form is submitted to MSDW Advisors' Risk
               Management Department for approval. NO employee may apply for an
               MSDW ONLINE ACCOUNT ONLINE. A copy of the MSDW Employee Account
               Request Form, which may be revised at any time, is attached as
               Exhibit C.

                                       5
<PAGE>
           (d) FORM

               Clearance must be obtained by completing and signing the
               Securities Transaction Approval Form provided for that purpose by
               MSDW Advisors and obtaining the signature of the correct
               Department indicated in sub-section C.1 (a) and any two of the
               Clearing Officers. The form must also indicate the name of the
               individual's Financial Advisor and the Branch Office Number,
               whether the account is an MSDW Online Account, as well as other
               required information.

               If you have more than one account under your control, indicate on
               the approval sheet for which account the trade is intended.
               ADDITIONALLY, PLEASE ADVISE YOUR FINANCIAL ADVISOR OR MSDW ONLINE
               TO SEND DUPLICATE COPIES OF YOUR CONFIRMATION SLIPS AND BROKER
               STATEMENTS TO THE MSDW Advisors' Risk Management Department FOR
               EACH ACCOUNT UNDER YOUR CONTROL.

           (e) FILING

               After all required signatures are obtained, the Securities
               Transaction Approval Form must be filed with the Risk Management
               Department of MSDW Advisors by noon of the day following
               execution of the trade for filing in the respective individual's
               Code of Ethics file. A copy is retained by the employee for his
               or her records. (If a preclearance request is denied, a copy of
               the form will be maintained with MSDW Advisors' Risk Management
               Department.)

       2.  FACTORS CONSIDERED IN CLEARANCE OF PERSONAL TRANSACTIONS

           In addition to the limitations and restrictions set forth under B
           above, the Clearing Officers, in keeping with the general principles
           and objectives of this Code of Ethics, may refuse to grant clearance
           of a personal transaction in their sole discretion without being
           required to specify any reason for the refusal. Generally, the
           Clearing Officers will consider the following factors in determining
           whether or not to clear a proposed transaction:

           (a) Whether the amount or the nature of the transaction or person
               making it is likely to affect the price or market of the
               security.

           (b) Whether the individual making the proposed purchase or sale is
               likely to benefit from purchases or sales being made or
               considered on behalf of any Morgan Stanley Dean Witter Fund or
               client.

           (c) Whether the transaction is non-volitional on the part of the
               individual.

       3.  EXEMPT SECURITIES

           (a) The securities listed below are exempt from the restrictions of
               sub-sections (B) (1) and (7), the advance clearance requirement
               of sub-section C AND the quarterly and annual reporting
               requirements of sub-section D. Therefore, it is not necessary to
               obtain advance clearance for personal transactions in any of the
               following securities nor is it necessary to report such
               securities in the quarterly transaction reports or annual
               securities holdings list:

               (i) U.S. Government Securities;

               (ii) Bank Certificates of Deposit;

               (iii) Bankers' Acceptances;

               (iv) Commercial Paper;

                                       6
<PAGE>
               (v) Purchases which are part of an automatic dividend
                   reinvestment plan (All employees with dividend reinvestment
                   plans must submit a memorandum to MSDW Advisors' Risk
                   Management Department and sales must be pre-approved); and

               (vi) Open-end investment companies (mutual funds) (Closed-end
                   funds must be pre-approved).

           (b) In addition, the following securities are exempt from the
               restrictions of sub-sections B (1) and (7) and the advance
               clearance requirement of sub-section C, but are subject to the
               quarterly and annual reporting requirements of sub-section D:

               (i) Unit Investment Trusts; and

               (ii) Morgan Stanley Dean Witter & Co. stock (including exercise
                   of stock option grants), due to the fact that it may not be
                   purchased by any actively managed Morgan Stanley Dean Witter
                   Fund (other than index-type funds) or for any MSDW Advisors
                   Managed Account. The restrictions imposed by Morgan Stanley
                   Dean Witter & Co. on Senior Management and other persons in
                   connection with transactions in Morgan Stanley Dean Witter &
                   Co. stock are not affected by the exemption of Morgan Stanley
                   Dean Witter & Co. stock from the advance clearance
                   requirements of this Code, and continue in effect to the
                   extent applicable.

       4.  ACCOUNTS COVERED

           Advance clearance must be obtained for any personal transaction in a
           security by an Access Person if such Access Person has, or as a
           result of the transaction acquires, any direct or indirect beneficial
           ownership in the security.

           The term "beneficial ownership" is defined by rules of the SEC which
           will be applicable in all cases. Generally, under the SEC rules, a
           person is regarded as having beneficial ownership of securities held
           in the name of:

           (a) a husband, wife or a minor child; OR

           (b) a relative sharing the same house; OR

           (c) anyone else if the Access Person:

               (i) obtains benefits substantially equivalent to ownership of the

           The responsibility for taking the initiative to report is imposed on
           each individual required to make a report. Any effort by MSDW
           Advisors to facilitate the reporting process does not change or alter
           that responsibility.

       5.  WHERE TO FILE REPORT

           All reports must be filed with the Risk Management Department of MSDW
           Advisors.

           filed by Access Persons.

    Investment Officer and the General Counsel of MSDW Advisors, will review and
    consider any proper request of an Access Person for relief or exemption from
    any restriction, limitation or procedure contained herein, which
    restriction, limitation or procedure is claimed to cause a hardship for such
    Access Person. The committee shall meet on an ad hoc basis, as deemed
    necessary upon written request by an Access Person, stating the basis for
    his or her request for relief. The committee's decision is solely within its
    complete discretion.

VII. SERVICE AS DIRECTOR

     No Access Person may serve on the board of any company without prior
     approval of the Code of Ethics Review Committee. If such approval is
     granted, it will be subject to the implementation of Chinese Wall
     procedures to isolate investment personnel serving as directors from making
     investment decisions for Morgan Stanley Dean Witter Funds or MSDW Advisors
     Managed Accounts concerning the company in question.

VIII. GIFTS

      including gifts and gratuities, in excess of $100 per year from any person
      or entity that does business with any Morgan Stanley Dean Witter Fund or
      MSDW Advisors Managed Account, not including occasional meals or tickets
      to theater or sporting events or other similar entertainment.

IX. SANCTIONS

    Upon discovering a violation of this Code, MSDW Advisors may impose such
    sanctions as it deems appropriate, including, but not limited to, a
    reprimand (orally or in writing), demotion, and suspension or termination of
    employment. The CEO of MSDW Advisors, in his sole discretion, is authorized
    to determine the choice of sanctions to be imposed in specific cases,
    including termination of employment of any employee.

X. EFFECTIVE DATE

I.  INTRODUCTION

        This Code of Ethics is adopted by the investment companies listed on
    Schedule A attached hereto, which list may be amended from time to time
    (each a "Fund" and collectively the "Morgan Stanley Dean Witter Funds" or
    the "Funds"), in compliance with Rule 17j-1 promulgated by the Securities
    and Exchange Commission ("SEC") under the Investment Company Act of 1940, as
    amended. This Code covers all persons who are "Access Persons," as that term
    is defined in Rule 17j-1. To the extent that any such individuals are
    "Access Persons" under the Code of Ethics of the Funds' Investment Advisor,
    Investment Manager, or Sub-Advisor, as applicable (any such entity herein
    referred to as "Investment Advisor"), whose Codes have also been established
    pursuant to Rule 17j-1, compliance by such individuals with the provisions
    of the Code of the applicable Investment Advisor shall constitute compliance
    with this Code.

II. PERSONAL TRANSACTIONS

    A.  REPORTS OF TRANSACTIONS - INDEPENDENT DIRECTORS/TRUSTEES

        An Independent Director/Trustee of a Morgan Stanley Dean Witter Fund
    shall report quarterly to the Fund any personal transaction in a security if
    he or she knows or should know at the time of entering into the transaction
    that: (a) the Fund has engaged in a transaction in the same security within
    the last 15 days, or is engaging in such transaction or is going to engage
    in a transaction in the same security in the next 15 days, or (b) the Fund
    or its Investment Advisor has within the last 15 days considered a
    transaction in the same security or is considering a transaction in the
    security or within the next 15 days is going to consider a transaction in
    the security.

    B.  REPORTS OF TRANSACTIONS, BROKERAGE ACCOUNTS AND HOLDINGS - ACCESS
       PERSONS WHO ARE NOT INDEPENDENT DIRECTORS/ TRUSTEES

        An Access Person who is not an Independent Director/Trustee of a Morgan
    Stanley Dean Witter Fund shall report all non-exempt securities transactions
    and new brokerage accounts on a quarterly basis.

        An Access Person who is not an Independent Director/Trustee of a Morgan
    Stanley Dean Witter Fund shall provide an annual listing of holdings of (i)
    all securities beneficially owned as of December 31 of the preceding year,
    except securities exempt from pre-clearance and reporting under Section D.,
    (2) hereof listing the title of the security, number of shares held, and
    principal amount of the security, (ii) the name of any broker dealer or
    financial institution where the account(s) are maintained, as of December 31
    of the preceding year (a current listing will also be required upon the
    effectiveness of this Code) and (iii) the date the Report is submitted by
    the Access Person. The information must be current as of a date not more
    than 30 days before the report is submitted. New Access Persons, who are not
    Independent Directors/Trustees of a Morgan Stanley Dean Witter Fund, will be
    required to provide a listing of all non-exempt securities holdings, with
    the information set forth above, as of the date of commencement of
    employment as well as a listing of all outside brokerage accounts no later
    than ten days after that person becomes an Access Person.

    C.  REPORTS OF TRANSACTIONS, BROKERAGE ACCOUNTS AND HOLDINGS - GENERAL

        Any quarterly report required under A or B above must be made within ten
    days after the end of the calendar quarter in which the personal transaction
    occurred. The report may be made on the form provided by the Investment
    Advisor or may consist of a broker statement that provides at least the same
    information. In the event that MSDW Advisors already maintains a record of
    the required information, an Access Person may satisfy this requirement by
    (i) confirming in writing (which may include e-mail) the accuracy and
    completeness of the record and disclose the beneficial ownership of
<PAGE>
    securities (if any) not listed on the account statement and (ii) recording
    the date of the confirmation. Copies of the Investment Advisor's forms,
    which may be revised at any time, are attached.

        The Funds' Compliance Officer will identify and advise all Access
    Persons, including the Independent Directors/Trustees, subject to the
    reporting requirement under A or B above, of their reporting requirement.
    Each report required under A or B above will be submitted for review by the
    Compliance Officer or Compliance Coordinator in the Risk Management
    Department of the Investment Advisor.

    D.  DEFINITIONS AND EXEMPTIONS

       (1) DEFINITIONS

           For purposes of this Code the term "personal transaction" means the
       purchase or sale, or other acquisition or disposition, of a security for
       the account of the individual making the transaction or for an account in
       which he or she has, or as a result of the transaction acquires, any
       direct or indirect beneficial ownership in a security.

           The term "beneficial ownership" is defined by rules of the SEC.
       Generally, under SEC rules a person is regarded as having beneficial
       ownership of securities held in the name of:

           (a) a husband, wife, or minor child;

           (b) a relative sharing the same house;

           (c) anyone else if the access person -

               (i) obtains benefits substantially equivalent to ownership of the
                   securities; or

               (ii) can obtain ownership of the securities immediately or at
                   some future time.

           The term "Access Person" is defined by rules of the SEC as (i) any
       director, officer, or general partner of a fund or of a fund's investment
       adviser, or any employee of a fund or of a fund's investment adviser who,
       in connection with his or her regular functions or duties, participates
       in the selection of a fund's portfolio securities or who has access to
       information regarding a fund's future purchases or sales of portfolio
       securities; or (ii) any director, officer, or general partner of a
       principal underwriter who in the ordinary course of business, makes,
       participates in or obtains information regarding, the purchase or sale of
       securities for the fund for which the principal underwriter acts, or
       whose functions or duties in the ordinary course of business relate to
       the making of any recommendation to the fund regarding the purchase or
       sale of securities.

       (2) EXEMPTIONS

           No report is required for a personal transaction in any of the
       following securities:

               (i) Securities issued by the U.S. Government;

               (ii) Bank certificates of deposit;

               (iii) Bankers' acceptances;

               (iv) Commercial paper;

               (v) Open-end mutual fund shares.

           Also, no report is required with respect to any account over which
       the access person has no influence or control.

III. CODE VIOLATIONS

        Any officer of a Morgan Stanley Dean Witter Fund who discovers a
    violation or apparent violation of this Code by an access person shall bring
    the matter to the attention of the Chief Executive Officer or General
    Counsel of the Fund who shall then report the matter to the Board of
    Directors or the Board of Trustees, as the case may be, of the fund. The
    Board shall determine
<PAGE>
    whether a violation has occurred and, if it so finds, may impose such
    sanctions, if any, as it considers appropriate.

IV. ADMINISTRATION OF CODE OF ETHICS

        On a quarterly basis, the Board of Directors or the Board of Trustees of
    each of the Funds shall be provided with a written report by each of the
    Funds and the Investment Advisors, that describes any new issues arising
    under the Code of Ethics, including information on material violations of
    the Code of Ethics or procedures and sanctions imposed, and certifies that
    each Fund and the Investment Advisors have adopted procedures reasonably
    necessary to prevent Access Persons from violating the Code of Ethics.
