THE FUND

[GRAPHIC OMITTED]


             INVESTMENT OBJECTIVE
- --------------------------------------------------
Morgan Stanley Dean Witter Short-Term U.S. Treasury Trust (the "Fund") seeks
current income, preservation of principal and liquidity.


[GRAPHIC OMITTED]


             PRINCIPAL INVESTMENT STRATEGIES
- ----------------------------------------------------------------
The Fund will invest all of its net assets in U.S. Treasury securities. The
Fund's "Investment Manager," Morgan Stanley Dean Witter Advisors Inc., seeks to
maintain a portfolio with a dollar-weighted average maturity of less than 3
years.

(sidebar)
INCOME
An investment objective having the goal of selecting securities to pay out
income rather than rise in price.
(end sidebar)

U.S. Treasury securities are direct obligations of the U.S. government and can
take the form of bonds, notes or bills. The U.S. government borrows money from
the investor who buys the security. U.S. Treasury securities generally pay
interest at regular intervals until they mature, at which point investors get
their principal back. U.S. Treasury securities are backed by the "full faith
and credit" of the U.S. government.

ZERO COUPON TREASURY SECURITIES. A portion of the U.S. Treasury securities
purchased by the Fund may be "zero coupon" Treasury securities. These are U.S.
Treasury notes and bonds which have been stripped of their unmatured interest
coupons and receipts or which are certificates representing interests in such
stripped debt obligations and coupons. Such securities are purchased at a
discount from their face amount, giving the purchaser the right to receive
their full value at maturity. A zero coupon security pays no interest to its
holder during its life. Its value to an investor consists of the difference
between its face value at the time of maturity and the price for which it was
acquired, which is generally an amount significantly less than its face value
(sometimes referred to as a "deep discount" price).

In pursuing the Fund's investment objective, the Investment Manager has
considerable leeway in deciding which investments it buys, holds or sells on a
day-to-day basis -- and which trading strategies it uses. For example, the
Investment Manager in its discretion may determine to use some permitted
trading strategies while not using others.


[GRAPHIC OMITTED]


             PRINCIPAL RISKS
- -------------------------------------------
There is no assurance that the Fund will achieve its objective. The Fund's
share price will fluctuate with changes in the market value of the Fund's
portfolio securities. The Fund's yield also will vary based on the yield of the
Fund's portfolio securities. Neither the value nor the yield of the U.S.
government securities that the Fund invests in (or the value or yield of the
Fund's shares) is guaranteed by the U.S. government. When you sell Fund shares,
they may be worth less than what you paid for them and, accordingly, you can
lose money investing in this Fund.

U.S. TREASURY SECURITIES. A principal risk of investing in the Fund is
associated with its U.S. Treasury securities, which are fixed-income
securities. All fixed-income securities are subject to two types of risk:
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/or repay
the principal on its debt. The credit risk associated with U.S. Treasury
securities is minimal.


                                                                               1

<PAGE>


Interest rate risk refers to fluctuations in the value of a fixed-income
security resulting from changes in the general level of interest rates. When
the general level of interest rates goes up, the prices of most fixed-income
securities go down. When the general level of interest rates goes down, the
prices of most fixed-income securities go up. As merely illustrative of the
relationship between fixed-income securities and interest rates, the following
table shows how interest rates affect bond prices.

- -------------------------------------------------------------------
</TABLE>

Coupons reflect yields on Treasury securities as of December 31, 1998. The
table is an illustration and does not represent expected yields or share price
changes of any Morgan Stanley Dean Witter mutual fund.

The interest earned on zero coupon Treasury securities is, implicitly,
automatically compounded and paid out at maturity. While such compounding at a
constant rate eliminates the risk of receiving lower yields upon reinvestment
of interest if prevailing interest rates decline, the owner of a zero coupon
security will be unable to participate in higher yields upon reinvestment of
interest received if prevailing interest rates rise. For this reason, zero
coupon securities are subject to substantially greater market price
fluctuations during periods of changing prevailing interest rates than are
comparable debt securities which make current distributions of interest.

The performance of the Fund also will depend on whether the Investment Manager
is successful in pursuing the Fund's investment strategy.

Shares of the Fund are not bank deposits and are not guaranteed or insured by
the FDIC or any other government agency.

             ADDITIONAL INVESTMENT STRATEGY INFORMATION
- -------------------------------------------------------------------------------

This section provides additional information relating to the Fund's principal
strategies.

The Fund may engage in active and frequent trading of portfolio securities to
achieve its principal investment strategies. The portfolio turnover rate is not
expected to exceed 200% annually under normal circumstances. A high turnover
rate will increase Fund brokerage costs. It also may increase the Fund's
capital gains, which are passed along to Fund shareholders as distributions.
This, in turn, may increase your tax liability as a Fund shareholder. See the
sections on "Distributions" and "Tax Consequences."

The percentage limitations relating to the composition of the Fund's portfolio
apply at the time the Fund acquires an investment and refers to the Fund's net
assets unless otherwise noted. Subsequent percentage changes that result from
market fluctuations will not require the Fund to sell any portfolio security.

             ADDITIONAL RISK INFORMATION
- -----------------------------------------------------------
This section provides additional information relating to the principal risks of
investing in the Fund.

YEAR 2000. The Fund could be adversely affected if the computer systems
necessary for the efficient operation of the Investment Manager, the Fund's
other service providers and the markets and governmental issuers in which the
Fund invests do not properly process and calculate date-related information
from and after January 1,

<PAGE>


2000. While year 2000-related computer problems could have a negative effect on
the Fund, the Investment Manager and its affiliates are working hard to avoid
any problems and to obtain assurances from their service providers that they
are taking similar steps.

In addition, it is possible that the markets for securities in which the Fund
invests may be detrimentally affected by computer failures throughout the
financial services industry beginning January 1, 2000. Improperly functioning
trading systems may result in settlement problems and liquidity issues. In
addition, governmental data processing errors also may result in overall
economic uncertainties. Accordingly, the Fund's investments may be adversely
affected.

             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 businesses:
securities, asset management and credit services. Its main business office is
located at Two World Trade Center, New York, New York 10048.

(sidebar)
MORGAN STANLEY DEAN WITTER ADVISORS INC.
The Investment Manager is widely recognized as a leader in the mutual fund
industry and together with Morgan Stanley Dean Witter Services Company Inc.,
its wholly-owned subsidiary, has more than $134.2 billion in assets under
management or administration as of May 31, 1999.
(end sidebar)

The Fund's portfolio is managed within the Investment Manager's Taxable Fixed
Income Group. Rajesh K. Gupta, Senior Vice President of the Investment Manager,
is the Fund's portfolio manager. Mr. Gupta has been a portfolio manager at the
Investment Manager for over five years.

The Fund pays the Investment Manager a monthly management fee as full
compensation for the services and facilities furnished to the Fund, and for
Fund expenses assumed by the Investment Manager. The fee is based on the Fund's
average daily net assets. For the fiscal year ended May 31, 1999, the Fund
accrued total compensation to the Investment Manager amounting to 0.35% of the
Fund's average daily net assets.


                                                                               5

SHAREHOLDER INFORMATION

[GRAPHIC OMITTED]


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

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.

The value of the Fund's portfolio securities is based on the securities' market
price when available. When a market price is not readily available, including
circumstances under which the Investment Manager determines that a security's
market price is not accurate, a portfolio security is valued at its fair value,
as determined under procedures established by the Fund's Board of Trustees. In
these cases, the Fund's net asset value will reflect certain portfolio
securities' fair value rather than their market price.

An exception to the Fund's general policy of using market prices concerns its
short-term debt portfolio securities. Short-term debt portfolio securities with
remaining maturities of sixty days or less at the time of purchase are valued
at amortized cost. However, if the cost does not reflect the securities' market
value, these securities will be valued at their fair value.

Advisor for further information about this service.
(end sidebar)

SUBSEQUENT INVESTMENTS SENT DIRECTLY TO THE FUND. In addition to buying
additional Fund shares for an existing account by contacting your Morgan
Stanley Dean Witter Financial Advisor, you may send a check directly to the
Fund. To buy additional shares in this manner:

o Write a "letter of instruction" to the Fund specifying the name(s) on the
  account, the account number, the social security or tax identification
  number, and the investment amount. The letter must be signed by the account
  owner(s).

o Make out a check for the total amount payable to: Morgan Stanley Dean Witter
  Short-Term U.S. Treasury Trust.

o Mail the letter and check to Morgan Stanley Dean Witter Trust FSB at P.O. Box
  1040, Jersey City, NJ 07303.


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 .35% for the sale and distribution of
shares. It also allows the Fund to pay for services to shareholders of shares.
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 in shares and may cost
you more than paying other types of sales charges.

             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 a No-Load Fund or Money
Market Fund. 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. An exchange privilege account also may be maintained for you
if you acquired Fund shares in exchange for shares of various TCW/DW Funds.


                                                                               7

<PAGE>


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

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. If you hold share certificates, no exchanges may be
processed until we have received all applicable share certificates.

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.
Certain services normally available to shareholders of Money Market Funds,
including the check writing privilege, are 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.

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 shares equal to the distribution
(12b-1) fees, if any, you paid on those shares while in the Fund up to the
amount of any applicable CDSC. See the Prospectus of the Fund that charges the
CDSC for more details.

<PAGE>


TAX CONSIDERATIONS OF EXCHANGES. If you exchange shares of the Fund for shares
of another Morgan Stanley Dean Witter Fund there are important tax
considerations. For tax purposes, the exchange out of the Fund is considered a
sale of Fund shares -- and the exchange into the other Fund is considered a
purchase. As a result, you may realize a capital gain or loss.

You should review the "Tax Consequences" section and consult your own tax
professional about the tax consequences of an exchange.

FREQUENT EXCHANGES. A pattern of frequent exchanges may result in the Fund
limiting or prohibiting, at its discretion, additional purchases and/or
exchanges. The Fund will notify you in advance of limiting your exchange
privileges.

For further information regarding exchange privileges, you should contact your
Morgan Stanley Dean Witter Financial Advisor or call (800) 869-NEWS.

                     exactly as their shares are registered. If the account is a joint account, the check
                     may contain one signature unless the joint owners have specified on an
                     investment application that all owners are required to sign checks. Only
                     accounts in which no share certificates have been issued are eligible for the
                     checkwriting privilege.
                     -------------------------------------------------------------------------------------
                     Payment of check proceeds normally will be made on the next business day after
                     we receive your check in proper form. Shares purchased by check (including a
                     certified or bank cashier's check) are not normally available to cover redemption
                     checks until fifteen days after Morgan Stanley Dean Witter Trust FSB receives
                     the check used for investment. A check will not be honored in an amount
                     exceeding the value of the account at the time the check is presented for
                     payment.

 By Letter           You may also sell your shares by writing a "letter of instruction" that includes:
[GRAPHIC OMITTED]    o your account number;
                     o the dollar amount or the number of shares you wish to sell; and
                     o the signature of each owner as it appears on the account.
                     -------------------------------------------------------------------------------------
                     If you are requesting payment to anyone other than the registered owner(s) or
                     that payment be sent to any address other than the address of the registered
                     owner(s) or pre-designated bank account, you will need a signature guarantee.
                     You can obtain a signature guarantee from an eligible guarantor acceptable to
                     Morgan Stanley Dean Witter Trust FSB. (You should contact Morgan Stanley
                     Dean Witter Trust FSB at (800) 869-NEWS for a determination as to whether a
                     particular institution is an eligible guarantor.)  A notary public cannot provide a
                     signature guarantee. Additional documentation may be required for shares held
                     by a corporation, partnership, trustee or executor.

 OPTIONS             PROCEDURES
- -------------------- -------------------------------------------------------------------------------------
 Systematic          If your investment in all of the Morgan Stanley Dean Witter Family of Funds has
 Withdrawal Plan     a total market value of at least $10,000, you may elect to withdraw amounts of
[GRAPHIC OMITTED]    $25 or more, or in any whole percentage of a Fund's balance (provided the
                     amount is at least $25), on a monthly, quarterly, semi-annual or annual basis,
                     from any Fund with a balance of at least $1,000. Each time you add a Fund to the
                     plan, you must meet the plan requirements.
                     -------------------------------------------------------------------------------------
                     When you sell Fund shares through the Systematic Withdrawal 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 more details.
                     -------------------------------------------------------------------------------------
                     To sign up for the Systematic Withdrawal Plan, contact your Morgan Stanley
                     Dean Witter Financial Advisor or call (800) 869-NEWS. You may terminate or
                     suspend your plan at any time. Please remember that withdrawals from the plan
                     are sales of shares, not Fund "distributions," and ultimately may exhaust your
                     account balance. The Fund may terminate or revise the plan at any time.
- -------------------- -------------------------------------------------------------------------------------
 By Telephone        To sell shares by telephone or wire, first complete a telephone redemption
 or Wire             application designating a bank account. Redemptions for more than $1,000 will
[GRAPHIC OMITTED]    be wired to your bank account (your bank may charge a fee for this service). For
                     redemptions for less than $1,000, a check will be mailed to your bank account. If
                     you hold share certificates, you may not redeem those shares by this method.
[GRAPHIC OMITTED]    For more information or to request a telephone redemption application, call
                     Morgan Stanley Dean Witter Trust FSB at (800) 869-NEWS.
                     -------------------------------------------------------------------------------------
</TABLE>

PAYMENT FOR SOLD SHARES. After we receive your complete instructions to sell as
described above, a check will be mailed to you within seven days, although we
will attempt to make payment within one business day. Payment may also be sent
to your brokerage account.

Payment may be postponed or the right to sell your shares suspended under
unusual circumstances. If you request to sell shares that were recently
purchased by check, payment of the sale proceeds may be delayed for the minimum
time needed to verify that the check has been honored (not more than fifteen
days from the time we receive the check).

INVOLUNTARY SALES. The Fund reserves the right, on sixty days' notice, to sell
the shares of any shareholder (other than shares held in an IRA or 403(b)
Custodial Account) whose shares, due to sales by the shareholder, have a value
below $1,000 or in the case of an account opened through EasyInvestSM, if after
12 months the shareholder has invested less than $10,000 in the account.

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.

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 sale of such shares.


[GRAPHIC OMITTED]


             DISTRIBUTIONS
- ----------------------------------------
The Fund passes substantially all of its earnings from income and capital gains
along to its investors as "distributions." The Fund earns interest from
fixed-income investments. Also, any zero coupon security investments under
federal law accrue a portion of the discount at which the security was purchased
as income even though the Fund receives no interest payments in cash. Interest
is passed along to Fund shareholders as "income dividend distributions." The
Fund realizes 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."

(sidebar)
TARGETED DIVIDENDS(SM)
You may select to have your Fund distributions automatically invested in
another Morgan Stanley Dean Witter Fund that you own. Contact your Morgan
Stanley Dean Witter Financial Advisor for further information about this
service.
(end sidebar)

Normally, income dividends are declared on each day the New York Stock Exchange
is open for business and are distributed to shareholders monthly. Capital
gains, if any, are usually distributed in December. The Fund, however, may
retain and reinvest any long-term capital gains. The Fund may at times make
payments from sources other than income or capital gains that represent a
return of a portion of your investment.

Distributions are reinvested automatically in additional shares of the Fund and
automatically credited to your account, unless you request in writing that all
distributions be paid in cash. If you elect the cash option, processing of your
dividend checks begins immediately following the monthly payment date, and the
Fund will mail a monthly dividend check to you normally during the first seven
days of the following 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.


[GRAPHIC OMITTED]


             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:

o The Fund makes distributions; and

o You sell Fund shares, including an exchange to another Morgan Stanley Dean
  Witter Fund.

TAXES ON DISTRIBUTIONS.

- --Federal Taxes. Your distributions are normally subject to federal income tax
when they are paid, whether you take them in cash or reinvest them in Fund
shares. Any income dividend distributions and any short-term capital gains are
taxable to you as ordinary income. Any long-term capital gain distributions are
taxable to you as long-term capital gains, no matter how long you have owned
shares in the Fund.


                                                                              11

<PAGE>


- --State and Local Taxes. Your income dividend distributions are normally exempt
from state and local income taxes. Any short-term capital gains are taxable to
you as ordinary income. Any long-term capital gain distributions are taxable to
you 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
distributions paid to you in the previous year. The statement provides full
information on your dividends and capital gains for tax purposes.

TAXES ON SALES. Your sale of Fund shares normally is subject to federal and
state income tax and may result in a taxable gain or loss to you. A sale also
may be subject to local income tax. Your exchange of Fund shares for shares of
another Morgan Stanley Dean Witter Fund is treated for tax purposes like a sale
of your original shares and a purchase of your new shares. Thus, the exchange
may, like a sale, result in a taxable gain or loss to you and will give you a
new tax basis for your new shares.

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.

FINANCIAL HIGHLIGHTS

The financial highlights table is intended to help you understand the Fund's
financial performance for the past 5 years of the Fund. Certain information
reflects financial results for a single Fund share. 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, 1177 Avenue
of the Americas, NY, NY 10036, whose report, along with the Fund's financial
statements, is included in the annual report, which is available upon request.

I. FUND HISTORY
- --------------------------------------------------------------------------------

     The Fund was organized as a Massachusetts business trust, under a
Declaration of Trust, on June 4, 1991 with the name Dean Witter Short-Term U.S.
Treasury Trust. Effective June 22, 1998, the Fund's name was changed to Morgan
Stanley Dean Witter Short-Term U.S. Treasury Trust.

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

A. CLASSIFICATION

     The Fund is an open-end, diversified management investment company whose
investment objective is to seek current income, preservation of principal 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," "Principal Risks," "Additional Investment Strategy
Information," and "Additional Risk Information."


     When-Issued and Delayed Delivery Securities and Firm Commitments. The Fund
may purchase U.S. Treasury securities on a when-issued or delayed delivery
basis or may purchase or sell U.S. Treasury securities on a firm commitment
basis. For example, the Fund may wish to purchase U.S. Treasury notes and bonds
sold at periodic U.S. Treasury auctions prior to their issuance
("when-issued"). When such 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 the commitment. While the Fund will only purchase
securities on a when-issued, delayed delivery or firm commitment basis 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 accrues to the purchaser
during this period. At the time the Fund makes the commitment to purchase or
sell securities on a when-issued, delayed delivery or firm commitment basis, 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. The Fund will also establish a
segregated account with its custodian bank in which it will continually
maintain cash or cash equivalents or other portfolio (U.S. Treasury) securities
equal in value to commitments to purchase securities on a when issued, delayed
delivery or firm commitment 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 cannot 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. The Investment
Manager, the Distributor and the Transfer Agent have been actively working on
necessary changes to their own computer systems to prepare for the year 2000
and expect that their systems will be adapted before that date, but there can
be no assurance that they will be successful, or that interaction with other
non-complying computer systems will not impair their services at that time.


     In addition, it is possible that the markets for securities in which the
Fund invests may be detrimentally affected by computer failures throughout the
financial services industry beginning January 1, 2000. Improperly functioning
trading systems may result in settlement problems and liquidity issues. In
addition, governmental data processing errors may result in production problems
for individual companies and overall economic uncertainties. Earnings of
individual issuers will be affected by remediation costs, which may be
substantial and may be reported inconsistently in U.S. and foreign financial
statements. Accordingly, the Fund's investments may be adversely affected.

C. FUND POLICIES/INVESTMENT RESTRICTIONS


     The investment objective, 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 current income, preservation of principal and liquidity.

     The Fund may not:

        1.  Invest more than 5% of the value of its total assets in the
            securities of any one issuer (other than obligations issued or
            guaranteed by the United States Government, its agencies or
            instrumentalities).

        2.  Purchase common stock, preferred stock, warrants, other equity
            securities, corporate bonds, municipal bonds or industrial revenue
            bonds.


        3.  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. Borrowing in the
            aggregate 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.

        4.  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 permitted borrowings or for temporary or emergency
            purposes.

        5.  Sell securities short or purchase securities on margin.

        6.  Write or purchase put or call options.

        7.  Underwrite the securities of other issuers or purchase restricted
            securities.

        8.  Purchase or sell real estate, real estate investment trust
            securities, commodities or commodity contracts or oil and gas
            interest.

        9.  Make loans to others except through the purchase of qualified debt
            obligations in accordance with the Funds investment objectives and
            policies.

        10. Issue senior securities as defined in the Investment Company Act
            except insofar as the Fund may be deemed to have issued a senior
            security by reason of: (a) borrowing money or (b) purchasing
            securities on a when-issued or delayed delivery basis or purchasing
            or selling securities on a forward commitment basis.

        11. Invest in securities of other investment companies, except as they
            may be acquired as part of a merger, consolidation, acquisition of
            assets or plan of reorganization.

     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. All of the
Trustees also serve as Trustees of "Discover Brokerage Index Series," a mutual
fund for which the Investment Manager is the investment advisor.

     The Trustees and executive officers of the Fund, their principal business
occupations during the last five years and their affiliations, if any, with the
Investment Manager, and with the 90 Morgan Stanley Dean Witter Funds and
Discover Brokerage Index Series, are shown below.

Services Company, are Assistant Secretaries of the Fund.

     INDEPENDENT TRUSTEES AND THE COMMITTEES. Law and regulation establish both
general guidelines and specific duties for the Independent Trustees. The Morgan
Stanley Dean Witter Funds seek as Independent 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. Three of them also serve as members of the
Derivatives Committee. In addition, three of the Trustees, including two
Independent Trustees, serve as members of the Insurance Committee.

     The Independent Trustees are charged with recommending to the full Board
approval of management, advisory and administration contracts, Rule 12b-1 plans
and distribution and underwriting


                                       9
<PAGE>

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 Trustees are required to
select and nominate individuals to fill any Independent 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 TRUSTEES FOR ALL
MORGAN STANLEY DEAN WITTER FUNDS. The Independent Trustees and the Funds'
management believe that having the same Independent 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
Trustees for each of the Funds or even of sub-groups of Funds. They believe
that having the same individuals serve as Independent Trustees of all the Funds
tends to increase their knowledge and expertise regarding matters which affect
the Fund complex generally and enhances 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 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 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
Trustees, of the caliber, experience and business acumen of the individuals who
serve as Independent 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.

     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 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 or 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 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 or 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 by
the Adopting Funds. Such benefits are not secured or funded by the Adopting
Funds.


- ----------
(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.

     The following table illustrates the retirement benefits accrued to the
Fund's Independent Trustees by the Fund for the fiscal year ended May 31, 1999
and by the 55 Morgan Stanley Dean Witter Funds (including the Fund) for the
calendar year ended December 31, 1998, and the estimated retirement benefits
for the Independent Trustees, to commence upon their retirement, from the Fund
as of the fiscal year ended May 31, 1999 and from the 55 Morgan Stanley Dean
Witter Funds as of the calendar year ended December 31, 1998.

V. INVESTMENT MANAGEMENT AND OTHER SERVICES
- --------------------------------------------------------------------------------

A. INVESTMENT MANAGER


     The Investment Manager to the Fund is Morgan Stanley Dean Witter Advisors
Inc., a Delaware corporation, whose address is Two World Trade Center, New
York, New York 10048. The Investment Manager is a wholly-owned subsidiary of
MSDW, a Delaware corporation. MSDW is a preeminent global financial services
firm that maintains leading market positions in each of its three primary
businesses: securities, asset management and credit services.

     Pursuant to an Investment Management Agreement (the "Management
Agreement") with the Investment Manager, the Fund has retained the Investment
Manager to 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 daily by applying the annual rate of 0.35% to the net assets of the
Fund determined as of the close of each business day.

     For the fiscal years ended May 31, 1997, 1998 and 1999, the Investment
Manager accrued total compensation under the Management Agreement in the
amounts of $902,158, $841,955 and $1,081,244, respectively.

     The Investment Manager has retained its wholly-owned subsidiary, MSDW
Services Company, to perform administrative services for the Fund.


                                       12
<PAGE>

B. PRINCIPAL UNDERWRITER

     The Fund's principal underwriter is the Distributor (which has the same
address as the Investment Manager). In this capacity, the Fund's shares are
distributed by the Distributor. The Distributor has entered into a selected
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
Delaware corporation, is a wholly-owned subsidiary of MSDW.

     The Distributor bears all expenses it may incur in providing services
under the Distribution Agreement. These expenses include the payment of
commissions for sales of the Fund's shares and incentive compensation to
Financial Advisors. The Distributor also pays certain expenses in connection
with the distribution of the Fund's shares, including the costs of preparing,
printing and distributing advertising or promotional materials, and the costs
of printing and distributing prospectuses and supplements thereto used in
connection with the offering and sale of the Fund's shares. The Fund bears the
costs of initial typesetting, printing and distribution of prospectuses and
supplements thereto to shareholders. The Fund also bears the costs of
registering the Fund and its shares under federal and state securities laws and
pays filing fees in accordance with state securities laws.

     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 AND FUND EXPENSES PAID BY THIRD
   PARTIES

     The Investment Manager manages the investment of the Fund's assets,
including the placing of orders for the purchase and sale of portfolio
securities. The Investment Manager obtains and evaluates the information and
advice relating to the economy, securities markets, and specific securities as
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: fees pursuant to the Fund's 12b-1
Plan; 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


                                       13
<PAGE>

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.


     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.


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' Financial
Advisors and other Selected Broker-Dealers' account executives 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 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 0.35 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 expenses will be reimbursable under the Plan. In
the case of all expenses other than expenses representing a residual to
Financial Advisors and other authorized financial representatives, such amounts
shall be 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 and other authorized financial representatives,
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 accrued a total of $1,060,017 pursuant to the Plan of
Distribution for the fiscal year ended May 31, 1998. It is estimated that the
amounts paid by the Fund for distribution were for expenses which related to
compensation of sales personnel and associated overhead expenses.


                                       14
<PAGE>

     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
last 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 the Plan is essential in order to enable
the Fund to continue to grow and avoid a pattern of net redemptions which, in
turn, is essential for effective investment management; and without the
compensation to individual brokers and the reimbursement of distribution and
account maintenance expenses of Dean Witter Reynolds's 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.

     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. 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.

                                       15
<PAGE>

     PricewaterhouseCoopers, LLP, 1177 Avenue of the Americas, NY, NY 10036

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

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

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

A. BROKERAGE TRANSACTIONS

     Subject to the general supervision of the Board of 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 May 31, 1997, 1998 and 1999, the Fund paid
no such brokerage commissions or concessions.

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. 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 May 31, 1997, 1998 and 1999, 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 May 31, 1997, 1998 and 1999, 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.


                                       16
<PAGE>

     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.

     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 May 31, 1999, the Fund did not pay any
brokerage commissions to brokers because of research services provided.


E. REGULAR BROKER-DEALERS

     During the fiscal year ended May 31, 1999, 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 May 31, 1999, 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 action of the
Trustees. In addition,


                                       17
<PAGE>

under certain circumstances the shareholders may call a meeting to remove
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 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.


B. OFFERING PRICE

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

     The net asset value per share of the Fund is determined by taking the
value of all the assets of the Fund, subtracting all liabilities, dividing by
the number of shares outstanding and adjusting the result to nearest cent. The
net asset value per share is determined by the Investment Manager as of 4:00
p.m. New York 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). The net asset value per share will not be determined on Good
Friday and on such other federal and non-federal holidays as are observed by
the New York Stock Exchange.


                                       18
<PAGE>

     In the calculation of the Fund's net asset value: (1) all portfolio
securities for which over-the-counter market quotations are readily available
are valued at the bid price; and (2) when market quotations are not readily
available, including circumstances under which it is determined by the
Investment Manager that sale or bid prices are not reflective of a security's
market value, portfolio securities are valued at their fair value as determined
in good faith under procedures established by and under the general supervision
of the Fund's Board of Trustees (valuation of securities for which market
quotations are not readily available may be based upon current market prices of
securities which are comparable in coupon, rating and maturity or an
appropriate matrix utilizing similar factors).

     Short-term taxable debt securities with remaining maturities of 60 days or
less at time of purchase are valued at amortized cost, unless the Board
determines such does not reflect the securities' market value, in which case
these securities will be valued at their fair value as determined by the Board
of Trustees. Other taxable short-term debt securities with maturities of more
than 60 days will be valued on a mark to market basis until such time as they
reach a maturity of 60 days, whereupon they will be valued at amortized cost
using their value on the 61st day unless the Trustees determine such does not
reflect the securities' fair value, in which case these securities will be
valued at their fair market value as determined by the Board of Trustees.

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

     The Fund generally will make two basic types of distributions: ordinary
dividends and long-term capital gain distributions. These two types of
distributions are reported differently on a shareholder's income tax return and
they are also subject to different rates of tax. The tax treatment of the
investment activities of the Fund will affect the amount and timing and
character of the distributions made by the Fund. Tax issues relating to the
Fund are not generally a consideration for shareholders such as tax exempt
entities and tax-advantaged retirement vehicles such as an IRA or 401(k) plan.
Shareholders are urged to consult their own tax professionals regarding
specific questions as to federal, state or local taxes.

     INVESTMENT COMPANY TAXATION. The Fund intends to remain qualified as a
regulated investment company under Subchapter M of the Internal Revenue Code of
1986. As such, the Fund will not be subject to federal income tax on its net
investment income and capital gains, if any, to the extent that it distributes
such income and capital gains to its shareholders.

     The Fund generally intends to distribute sufficient income and gains so
that the Fund will not pay corporate income tax on its earnings. The Fund also
generally intends to distribute to its shareholders in each calendar year a
sufficient amount of ordinary income and capital gains to avoid the imposition
of a 4% excise tax. However, the Fund may instead determine to retain all or
part of any net long-term capital gains in any year for reinvestment. In such
event, the Fund will pay federal income tax (and possibly excise tax) on such
retained gains.

     Gains or losses on sales of securities 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 certain tax rules, the Fund may be required to accrue a portion of
any discount at which certain securities are purchased as income each year even
though the Fund receives no payments in cash on the security during the year.
To the extent that the Fund invests in such securities, it would be required to
pay out such accrued discount as an income distribution in each year in order
to avoid taxation at the Fund level. Such distributions will be made from the
available cash of the Fund or by liquidation of portfolio securities if
necessary. If a distribution of cash necessitates the liquidation of portfolio
securities, the Investment Manager will select which securities to sell. The
Fund may realize a gain or loss from such sales. In the event the Fund realizes
net capital gains from such transactions, its shareholders may receive a larger
capital gain distribution, if any, than they would in the absence of such
transactions.

     TAXATION OF DIVIDENDS AND DISTRIBUTIONS--Federal Taxes. Shareholders
normally will have to pay federal income taxes on the dividends and other
distributions they receive from the Fund. Such


                                       19
<PAGE>

dividends and distributions, to the extent that they are derived from net
investment income or short-term capital gains, are taxable to the shareholder
as ordinary income regardless of whether the shareholder receives such payments
in additional shares or in cash.

     Distributions of net long-term capital gains, if any, are taxable to
shareholders as long-term capital gains regardless of how long a shareholder
has held the Fund's shares and regardless of whether the distribution is
received in additional shares or in cash. The Taxpayer Relief Act of 1997
reduced the maximum tax on long-term capital gains applicable to individuals
from 28% to 20%.

     Shareholders are generally taxed on any ordinary dividend or capital gain
distributions from the Fund in the year they are actually distributed. However,
if any such dividends or distributions are declared in October, November or
December and paid in January then such amounts will be treated for tax purposes
as received by the shareholders on December 31, to shareholders of record of
such month.

     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 investment income and short term capital
gains.

     State and Local Taxes. Because all States presently allow the pass-through
of federal obligation interest derived from specific federal obligations, it is
anticipated that substantially all of the interest income generated by the Fund
and paid out to shareholders as net investment income will be exempt from the
taxation of most state and local jurisdictions. Furthermore, any capital gains
realized by the Fund will not be exempt from state and local taxes. It should
be noted that although the Fund intends to invest only in securities the
pass-through income from which is believed exempt from state and local income
taxes, it is possible that a state or local taxing authority may seek to tax an
investor on a portion of the interest income of a particular government
obligation held by the Fund.

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

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
Plans."

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

     From time to time the Fund may quote its "yield" and/or its "total return"
in advertisements and sales literature.

     Yield is calculated for any 30-day period as follows: the amount of
interest income for each security in the Fund's portfolio is determined as
described below; the total for the entire portfolio constitutes the Fund's
gross income for the period. Expenses accrued during the period are subtracted
to arrive at "net investment income." The resulting amount is divided by the
product of the maximum offering price per share on the last day of the period
(reduced by any undeclared earned income per share that is expected to be
declared shortly after the end of the period) multiplied by the average number
of Fund shares outstanding during the period that were entitled to dividends.
This amount is added to 1 and raised to the sixth power. 1 is then subtracted
from the result and the difference is multiplied by 2 to arrive at the
annualized yield. Based on this calculation, the Fund's annualized yield for
the 30-day period ended May 31, 1999 was 4.38%.

     The Fund's "average annual total return" represents an annualization of
the Fund's total return over a particular period and is computed by finding the
annual percentage rate which will result in the ending redeemable value of a
hypothetical $1,000 investment made at the beginning of a one, five or ten year
period, or for the period from the date of commencement of the Fund's
operations, if shorter than any of


                                       20
<PAGE>

the foregoing. For the purpose of this calculation, it is assumed that all
dividends and distributions are reinvested. The formula for computing the
average annual total return involves a percentage obtained by dividing the
ending redeemable value by the amount of the initial investment, taking a root
of the quotient (where the root is equivalent to the number of years in the
period) and subtracting 1 from the result. Based on this calculation, the
average annual total returns of the Fund for the one and five year periods
ended May 31, 1999 and for the period August 13, 1991 (commencement of
operations) through May 31, 1999 were 4.50%, 5.42% and 5.20%, respectively.

     In addition, the Fund may compute its aggregate total return for specified
periods by determining the aggregate percentage rate which will result in the
ending value of a hypothetical $1,000 investment made at the beginning of the
period. For the purpose of this calculation, it is assumed that all dividends
and distributions are reinvested. The formula for computing aggregate total
return involves a percentage obtained by dividing the ending value by the
initial $1,000 investment and subtracting 1 from the result. The Fund's total
returns for the one and five year periods ended May 31, 1999 and for the period
August 13, 1991 (commencement of operations) through May 31, 1999 were 4.50%,
30.20% and 48.44%, respectively.

     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 1 to the Fund's
aggregate total return to date and multiplying by $10,000, $50,000 or $100,000,
respectively. Investments of $10,000, $50,000 and $100,000 in the Fund since
inception would have grown to $14,844, $74,220, and $148,440, respectively, at
May 31, 1999.

     The Fund from time to time may also advertise its performance relative to
certain performance rankings and indices compiled by recognized organizations.

MORGAN STANLEY DEAN WITTER SHORT-TERM U.S. TREASURY TRUST
NOTES TO FINANCIAL STATEMENTS May 31, 1999



1. ORGANIZATION AND ACCOUNTING POLICIES

Morgan Stanley Dean Witter Short-Term U.S. Treasury 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
objective is current income, preservation of principal and liquidity. The Fund
seeks to achieve its objective by investing its assets in U.S. Treasury
securities backed by the full faith and credit of the U.S. Government. The Fund
was organized as a Massachusetts business trust on June 4, 1991 and commenced
operations on August 13, 1991.

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 -- (1) portfolio securities for which
over-the-counter market quotations are readily available are valued at the
latest available bid price prior to the time of valuation; (2) when market
quotations are not readily available, including circumstances under which it is
determined by Morgan Stanley Dean Witter Advisors Inc. (the "Investment
Manager"), that sale or bid prices are not reflective of a security's market
value, portfolio securities are valued at their fair value as determined in
good faith under procedures established by and under the general supervision of
the Trustees (valuation of debt securities for which market quotations are not
readily available may be based upon current market prices of securities which
are comparable in coupon, rating and maturity or an appropriate matrix
utilizing similar factors); and (3) short-term debt securities having a
maturity date of more than sixty days at time of purchase are valued on a
mark-to-market basis until sixty days prior to maturity and thereafter at
amortized cost based on their value on the 61st day. Short-term debt securities
having a maturity date of sixty days or less at the time of purchase are valued
at amortized cost.


B. ACCOUNTING FOR INVESTMENTS -- Security transactions are accounted for on the
trade date (date the order to buy or sell is executed). Realized gains and
losses on security transactions are determined by the identified cost method.
Discounts are accreted over the life of the respective securities. Interest
income is accrued daily.


C. FEDERAL INCOME TAX STATUS -- It is the Fund's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute all of its taxable income to its shareholders.
Accordingly, no federal income tax provision is required.

MORGAN STANLEY DEAN WITTER SHORT-TERM U.S. TREASURY TRUST
NOTES TO FINANCIAL STATEMENTS May 31, 1999, continued

D. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- The Fund records dividends
and distributions to its shareholders on the ex-dividend date. The amount of
dividends and distributions from net investment income and net realized capital
gains are determined in accordance with federal income tax regulations which
may differ from generally accepted accounting principles. These "book/tax"
differences are either considered temporary or permanent in nature. To the
extent these differences are permanent in nature, such amounts are reclassified
within the capital accounts based on their federal tax-basis treatment;
temporary differences do not require reclassification. Dividends and
distributions which exceed net investment income and net realized capital gains
for financial reporting purposes but not for tax purposes are reported as
dividends in excess of net investment income or distributions in excess of net
realized capital gains. To the extent they exceed net investment income and net
realized capital gains for tax purposes, they are reported as distributions of
paid-in-capital.


2. INVESTMENT MANAGEMENT AGREEMENT

Pursuant to an Investment Management Agreement with the Investment Manager, the
Fund pays the Investment Manager a management fee, accrued daily and payable
monthly, by applying the annual rate of 0.35% to the net assets of the Fund
determined as of the close of each business day.

Under the terms of the 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, office space, facilities, equipment,
clerical, bookkeeping and certain legal services and pays the salaries of all
personnel, including officers of the Fund who are employees of the Manager. The
Investment Manager also bears the cost of telephone services, heat, light,
power and other utilities provided to the Fund.


3. PLAN OF DISTRIBUTION

Morgan Stanley Dean Witter Distributors Inc. (the "Distributor"), an affiliate
of the Investment Manager, is the distributor of the Fund's shares and, in
accordance with a Plan of Distribution (the "Plan") pursuant to Rule 12b-1
under the Act, finances certain expenses in connection with the distribution of
shares of the Fund.

Under the Plan, 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, Morgan Stanley Dean Witter Financial
Advisors, other employees and selected broker-dealers; (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 Fund is authorized to reimburse the Distributor for specific expenses the
Distributor incurs or plans to incur in promoting the distribution of the
Fund's shares. The amount of each monthly reimbursement payment may in no event
exceed an amount equal to a payment at the annual rate of 0.35% of the Fund's
average daily net assets during the month. For the year ended May 31, 1999, the
distribution fee was accrued at the annual rate of 0.34%.


4. SECURITY TRANSACTIONS AND TRANSACTIONS WITH AFFILIATES

The cost of purchases and proceeds from sales/maturities of portfolio
securities for the year ended May 31, 1999 aggregated $533,813,143 and
$457,536,267, respectively.

Morgan Stanley Dean Witter Trust FSB, an affiliate of the Investment Manager
and Distributor, is the Fund's transfer agent. At May 31, 1999, the Fund had
transfer agent fees and expenses payable of approximately $900.

The Fund has an unfunded noncontributory defined benefit pension plan covering
all independent Trustees of the Fund who will have served as independent
Trustees for at least five years at the time of retirement. Benefits under this
plan are based on years of service and compensation during the last five years
of service. Aggregate pension costs for the year ended May 31, 1999 included in
Trustees' fees and expenses in the Statement of Operations amounted to $6,942.
At May 31, 1999, the Fund had an accrued pension liability of $43,162 which is
included in accrued expenses in the Statement of Assets and Liabilities.

6. FEDERAL INCOME TAX STATUS

At May 31, 1999, the Fund had a net capital loss carryover of approximately

=========       ======      ====     ====     ===
</TABLE>

Capital losses incurred after October 31 ("post-October losses") within the
taxable year are deemed to arise on the first business day of the Fund's next
taxable year. The Fund incurred and will elect to defer net capital losses of
approximately $234,000 during fiscal 1999.

As of May 31, 1999, the Fund had temporary book\tax differences primarily
attributable to post-October losses.


7. RISK RELATING TO CERTAIN FINANCIAL INSTRUMENTS

The Fund may invest a portion of its assets in zero coupon U.S. Treasury
securities. Zero coupon securities are subject to substantially greater market
fluctuations during periods of changing prevailing interest rates than are
comparable debt securities.

MORGAN STANLEY DEAN WITTER SHORT-TERM U.S. TREASURY TRUST
REPORT OF INDEPENDENT ACCOUNTANTS


TO THE SHAREHOLDERS AND TRUSTEES
OF MORGAN STANLEY DEAN WITTER SHORT-TERM U.S. TREASURY 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 present fairly, in all
material respects, the financial position of Morgan Stanley Dean Witter
Short-Term U.S. Treasury Trust (the "Fund") at May 31, 1999, 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 generally accepted
accounting principles. 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 generally accepted auditing standards
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 May 31, 1999 by correspondence with the
custodian, provide a reasonable basis for the opinion expressed above.

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.

                                       2
<PAGE>

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

            MORGAN STANLEY DEAN WITTER SHORT-TERM U.S. TREASURY 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

Short-Term U.S. Treasury Trust dated June 4, 1991, 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, except to the extent otherwise
required by Section 16(c) of the 1940 Act, as made applicable to the Trust by
the provisions of Section 2.3 of the Declaration. Such request shall state the
purpose or purposes of such meeting and the matters proposed to be acted on
thereat. Except to the extent otherwise required by Section 16(c) of the 1940
Act, as made applicable to the Trust by the provisions of Section 2.3 of the
Declaration, 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

<PAGE>

issued and outstanding and entitled to vote thereat, present in person or
represented by proxy, shall be 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

                                       2
<PAGE>

made by the Trustees in advance of the convening of the meeting or at the
meeting by the person acting 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

                                        3
<PAGE>

or permitted to be taken at any meeting of the Trustees may be taken without a
meeting if a consent in 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.

                                        4
<PAGE>

     (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).

         (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

                                        5
<PAGE>

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.

     (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

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,

                                        6

acknowledge or verify any instrument in more than one capacity. The executive

more Assistant Vice Presidents, Assistant Secretaries and Assistant Treasurers

officers and agents as the Trustees shall at any time or from time to time deem
advisable.

     SECTION 6.3. Term and Removal and Vacancies. Each officer of the Trust
shall hold office until his or her successor is elected and has qualified. Any
officer or agent of the Trust may be removed by the Trustees whenever, in their
judgment, the best interests of the Trust will be served thereby, but such
removal shall be without prejudice to the contractual rights, if any, of the
person so removed.

     SECTION 6.4. Compensation of Officers. The compensation of officers and

officer of the Trust, shall preside at all meetings of the Shareholders and of
the Trustees, shall have general and active management of the business of the

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
Presidents in such order as may be determined from time to time by the Trustees
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 duties as the Trustees or the Chairman may from time to time prescribe.

     SECTION 6.10. The Secretary. The Secretary shall attend all meetings of

Chairman may from time to time prescribe. He or she shall keep in safe custody
the seal of the Trust and affix or cause the same to be affixed to any
instrument requiring it, and, when so affixed, it shall be attested by his or
her signature or by the signature of an Assistant Secretary.

powers as the Trustees or the Chairman may from time to time prescribe.

     SECTION 6.12. The Treasurer. The Treasurer shall be the chief financial
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 or she shall render to the Trustees and the Chairman, whenever
any of them require it, an account of his or her transactions as Treasurer and

other officer or officers or to any Trustee or Trustees.

                                   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

                                        8
<PAGE>

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 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.

     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.

     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

                  MORGAN STANLEY DEAN WITTER DISTRIBUTORS INC.
                       OMNIBUS SELECTED DEALER AGREEMENT

Dear Sir or Madam:

    We, Morgan Stanley Dean Witter Distributors Inc. (the "Distributor") have a
distribution agreement (the "Distribution Agreement") with each of the open-end
investment companies listed in Schedule A attached hereto (each, a "Fund"),
pursuant to which we act as the Distributor for the sale of each Fund's shares
of common stock or beneficial interest, as the case may be, (the "Shares").
Under the Distribution Agreement, we have the right to distribute Shares for
resale.

    Each Fund is an open-end management investment company registered under the
Investment Company Act of 1940, as amended, and the Shares being offered to the
public are registered under the Securities Act of 1933, as amended (the
"Securities Act"). You have received a copy of the Distribution Agreements
between us and each Fund and reference is made herein to certain provisions of
such Distribution Agreements. The terms used herein, including "Prospectus" and
"Registration Statement" of each Fund and "Selected Dealer" shall have the same
meaning in this Agreement as in the Distribution Agreements. As principal, we
offer to sell Shares to your customers, upon the following terms and
conditions:

    1. In all sales of Shares to the public you shall act on behalf of your
customers which for purposes of this Agreement are limited to customers for
which Nations Banc Investments, Inc. is the Introducing Broker, and in no
transaction shall you have any authority to act as agent for a Fund, for us or
for any Selected Dealer.

    2. Orders received from you will be accepted through us or on our behalf
only at the public offering price applicable to each order, as set forth in the
applicable current Prospectus. The procedure relating to the handling of orders
shall be subject to written instructions which we or the applicable Fund shall
forward from time to time to you. All orders are subject to acceptance or
rejection by us or a Fund in the sole discretion of either. The Distributor of
the Fund will promptly notify you in writing of any such rejection.

    3. You shall not place orders for any Shares unless you have already
received purchase orders for such Shares at the applicable public offering
price and subject to the terms hereof and of the applicable Distribution
Agreement and Prospectus. In connection herewith, you agree to abide by the
terms of the applicable Distribution Agreement and Prospectus to the extent
required hereunder. Furthermore, you agree that (i) you will offer or sell any
of the Shares only under circumstances that will result in compliance with all
applicable Federal and state securities laws; (ii) you will not furnish or
cause to be furnished to any person any information relating to the Shares
which is inconsistent in any respect with the information contained in the
applicable Prospectus (as then amended or supplemented) or cause any
advertisements to be published by radio or television or in any newspaper or
posted in any public place or use any sales promotional material without our
consent and the consent of the applicable Fund; and (iii) you will endeavor to
obtain proxies from purchasers of Shares. You also agree that you will be
liable to Distributor for payment of the purchase price for Shares purchased by
customers and that you shall make payment for such shares when due.

    4. We will compensate you for sales of shares of the Funds and personal
services to Fund shareholders by paying you a sales charge and/or other
commission (which may be in the form of a gross sales credit and/or an annual
residual commission) and/or a service fee, each as separately agreed by you and
us with respect to each Fund.

    5. If any Shares sold to your customers under the terms of this Agreement
are repurchased by us for the account of a Fund or are tendered for redemption
within seven business days after the date of the confirmation of the original
purchase by you, it is agreed that you shall forfeit your right to, and refund
to us, any commission received by you with respect to such Shares.

    6. No person is authorized to make any representations concerning the
Shares or the Funds except those contained in the current applicable Prospectus
and in such printed information subsequently issued by us or a Fund as
information supplemental to such Prospectus. In selling Shares, you shall rely
solely on the representations contained in the applicable Prospectus and
supplemental information mentioned above. Any printed information which we
furnish you other than the Prospectus and the Funds' periodic reports and

<PAGE>

proxy solicitation materials are our sole responsibility and not the
responsibility of the Funds, and you agree that the Funds shall have no
liability or responsibility to you in these respects unless expressly assumed
in connection therewith.

    7. You are hereby authorized (i) to place orders directly with a Fund or
its agent for shares of the Fund to be sold by us subject to the applicable
terms and conditions governing the placement of orders for the purchase of Fund
Shares, as set forth in the Distribution Agreement, and (ii) to tender Shares
directly to the Fund or its agent for redemption subject to the applicable
terms and conditions set forth in the Distribution Agreement. We will provide
you with copies of any updates to the Distribution Agreement.

    8. We reserve the right in our discretion, without notice, to suspend sales
or withdraw the offering of Shares entirely. Each party hereto has the right to
cancel this agreement with respect to one or more Funds upon fifteen days prior
written notice to the other party.

    9. I. You shall indemnify and hold us harmless from and against any and all
losses, costs, (including reasonable attorney's fees) claims, damages and
liabilities which arise as a result of action taken pursuant to instructions
from you, or on your behalf to: (a)(i) place orders for Shares of a Fund with
the Fund's transfer agent or direct the transfer agent to receive instructions
for the order of Shares, and (ii) accept monies or direct that the transfer
agent accept monies as payment for the order of such Shares, all as
contemplated by and in accordance with Section 3 of the applicable Distribution
Agreement; (b)(i) place orders for the redemption of Shares of a Fund with the
Fund's transfer agent or direct the transfer agent to receive instruction for
the redemption of such Shares and (ii) to pay redemption proceeds or to direct
that the transfer agent pay redemption proceeds in connection with orders for
the redemption of Shares, all as contemplated by and in accordance with Section
4 of the applicable Distribution Agreement; Distributor agrees to indemnify and
hold harmless you and your affiliates, officers, directors, control persons and
employees from and against any and all losses, costs (including reasonable
attorney's fees), claims, damages and liabilities which arise as a result of
Distributor's failure to fulfill its obligations hereunder and from any alleged
inaccuracy, omission or misrepresentation contained in any prospectus or any
advertising, or sales literature prepared by Distributor or the Fund provided,
however, that in no case, (i) is this indemnity in favor of you or us and any
of other party's such controlling persons to be deemed to protect us or any
such controlling persons against any liability to which we or any such
controlling persons would otherwise be subject by reason of willful
misfeasance, bad faith or gross negligence in the performance of our duties or
by reason of reckless disregard of our obligations and duties under this
Agreement or the applicable Distribution Agreement; or (ii) are you to be
liable under the indemnity agreement contained in this paragraph with respect
to any claim made against us or any such controlling persons, unless we or any
such controlling persons, as the case may be, shall have notified you in
writing within a reasonable time after the summons or other first legal process
giving information of the nature of the claim shall have been served upon us or
such controlling persons (or after we or such controlling persons shall have
received notice of such service on any designated agent), notwithstanding the
failure to notify you of any such claim shall not relieve you from any
liability which you may have to the person against whom such action is brought
otherwise than on account of the indemnity agreement contained in this
paragraph.

    II. You will be entitled to participate at your own expense in the defense,
or, if you so elect, to assume the defense, of any suit brought to enforce any
such liability, but if you elect to assume the defense, such defense shall be
conducted by counsel chosen by you and reasonably satisfactory to us or such
controlling person or persons, defendant or defendants in the suit. In the
event you elect to assume the defense of any such suit and retain such counsel,
we or such controlling person or persons, defendant or defendants in the suit,
shall bear the fees and expenses of any additional counsel retained by them,
but, in case you do not elect to assume the defense of any such suit, you will
reimburse us or such controlling person or persons, defendant or defendants in
the suit, for the reasonable fees and expenses of any counsel retained by them.
Each party shall promptly notify the other party to this Agreement of the
commencement of any litigation or proceedings against it or any of its officers
or directors in connection with the issuance or sale of the Shares pursuant to
this Agreement.

                                       2

    III. If the indemnification provided for in this Section 9 is unavailable
or insufficient to hold harmless the Distributor, as provided above in respect
of any losses, claims, damages, liabilities or expenses (or actions in respect
thereof) referred to herein, then you shall contribute to the amount paid or
payable by us as a result of such losses, claims, damages, liabilities or
expenses (or actions in respect thereof) in such proportion as is appropriate
to reflect the relative benefits received by you on the one hand and us on the
other from the offering of the Shares. If, however, the allocation provided by
the immediately preceding sentence is not permitted by applicable law, then you
shall contribute to such amount paid or payable by such indemnified party in
such proportion as is appropriate to reflect not only such relative benefits
but also your relative fault on the one hand and our relative fault on the
other, in connection with the statements or omissions which resulted in such
losses, claims, damages, liabilities or expenses (or actions in respect
thereof), as well as any other relevant equitable considerations. You and we
agree that it would not be just and equitable if contribution were determined
by pro rata allocation or by any other method of allocation which does not take
into account the equitable considerations referred to above. The amount paid or
payable by us as a result of the losses, claims, damages, liabilities or
expenses (or actions in respect thereof) referred to above shall be deemed to
include any legal or other expenses reasonably incurred by us in connection
with investigating or defending any such claim. Notwithstanding the provisions
of this subsection (III), you shall not be required to contribute any amount in
excess of the amount by which the total price at which the Shares distributed
by you to the public were offered to the public exceeds the amount of any
damages which you have otherwise been required to pay by reason of such untrue
or alleged untrue statement or omission or alleged omission. No person guilty
of fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation.

    IV. Notwithstanding the provisions of subsections (I), (II) and (III), we
shall indemnify, defend and hold harmless you and your officers, directors,
employees, affiliates, agents, successors and assigns from and against any and
all claims and all related losses, expenses, damages, cost and liabilities
including reasonable attorneys' fees and expenses incurred in investigation or
defense, arising out of or related to any breach of any representation,
warranty or covenant by us contained in Section 15 of this Agreement.

    11. We shall have full authority to take such action as we may deem
advisable in respect of all matters pertaining to the distribution and
redemption of Shares. Neither party shall be under any liability to the other
party except for lack of good faith and for obligations expressly assumed
herein. Nothing contained in this paragraph is intended to operate as, and the
provisions of this paragraph shall not in any way whatsoever constitute, a
waiver by you of compliance with any provision of the Securities Act, or of the
rules and regulations of the Securities and Exchange Commission issued
thereunder.

    12. Each party represents that it is a member in good standing of the
National Association of Securities Dealers, Inc. and, with respect to any sales
in the United States, each party hereby agrees to abide by the Rules of Fair
Practice of such Association relating to the performance of the obligations
hereunder.

    13. We will inform you in writing as to the states in which we believe the
Shares have been qualified for sale under, or are exempt from the requirements
of, the respective securities laws of such states, but we assume no
responsibility or obligation as to your right to sell Shares in any
jurisdiction.

    14. Notwithstanding any other provision of this Agreement to the contrary,
we represent and warrant that the names and addresses of your customers (or
customers of your affiliates) which have or which may come to our attention in
connection with this Agreement are confidential and are your exclusive property
and shall not be utilized by us except in connection with the functions
performed by us in connection with this Agreement. Notwithstanding the
foregoing, should a customer request, that we or an organization affiliated
with us, provide services to such customer, we or such affiliated organization
shall in no way violate this representation and warranty, nor be considered in
breach of this Agreement.

    15. We represent, warrant, and covenant to you that the marketing
materials, any communications distributed to the public and training materials
designed by us or our agents relating to the product sold under this Agreement
are true and accurate and do not omit to state a fact necessary to make the

                                        3
<PAGE>

information contained therein not misleading and comply with applicable federal
and state laws. We further represent, warrant, and covenant to you that the
performance by us of our obligations under this Agreement in no way constitutes
an infringement on or other violation of copyright, trade secret, trademark,
proprietary information or non-disclosure rights of any other party.

    16. We shall maintain a contingency disaster recovery plan, and, in the
event you are so required by any regulatory or governmental agency, we shall
make such plan available to you for inspection at your office upon reasonable
advance notice by you. Each party agrees that it will at all times conduct its
activities under this Agreement in an equitable, legal and professional manner.

    17. We understand that the performance of your and our obligations under
this Agreement is subject to examination during business hours by your
authorized representatives and auditors and by federal and state regulatory
agencies, and we agree that upon being given reasonable notice and proper
identification we shall submit or furnish at a reasonable time and place to any
such representative or regulatory agency reports, information, or other data
relating to this Agreement as may reasonably be required or requested by you.
We shall maintain and make available to you upon reasonable notice all
material, data, files, and records relating to this Agreement for a period of
not less than three years after the termination of this Agreement.

    18. The sales, advertising and promotional materials designed by either
party or its agents relating to products sold under this Agreement shall comply
with applicable federal and state laws. Each party agrees that the sales,
advertising and promotional materials shall be made available to the other
party prior to distribution to your employees or customers.

    19. Any controversy or claim between or among the parties hereto arising
out of or relating to this Agreement, including any claim based on or arising
from an alleged tort, shall be determined by binding arbitration in accordance
with the rules of the National Association of Securities Dealers, Inc. Judgment
upon any arbitration award may be entered in any court having jurisdiction. Any
party to this Agreement may bring an action, including a summary or expedited
proceeding, to compel arbitration of any controversy or claim to which this
Agreement applies in any court having jurisdiction over such action.

    20. All notices or other communications under this Agreement shall be in
writing and given as follows:

                               RETIREMENT PLAN FOR
                             NON-INTERESTED TRUSTEES
                                  OR DIRECTORS

     Certain of the investment companies for which Morgan Stanley Dean Witter
Advisors Inc. ("MSDW Advisors") currently acts as manager or adviser adopted a
Retirement Plan for Non-Interested Trustees and Directors (the "Original Plan")
on February 21, 1991 (the "Commencement Date"). The Original Plan was amended
and restated on October 22, 1993, effective January 1, 1994 and further amended
by First Amendment dated December 19, 1995 and by Second Amendment dated May 8,
1997. The participating Funds now desire to amend and restate the Plan further
as provided herein effective as of the Commencement Date (as so amended, the
"Plan"), for the purposes of expanding the flexibility of Non-Interested
Trustees and Directors to make and change their elections of benefits.

     1. DEFINITIONS

     (a) "Independent Board Member" shall mean (i) a Trustee of an Adopting
Fund if the Adopting Fund is organized as a Massachusetts business trust, (ii)
a Director of an Adopting Fund if the Adopting Fund is organized as a
corporation, and (iii) a "director" (as such term is defined in Section
2(a)(12) of the Investment Company Act of 1940, as amended [the "Act"]) of an
Adopting Fund if the Adopting Fund is any other type of organization, who in
any such case is not an interested person (as such term is defined in Section
2(a)(19) of the Act) of MSDW Advisors.

     (b) "Eligible Board Member" shall mean an Independent Board Member who at
the time of Retirement (as hereinafter defined) has served as an Independent
Board Member of any Adopting Fund for at least five years, or such lesser
period as may be determined by the Board.

     (c) "Eligible Service" shall mean service as an Independent Board Member.

     (d) "Eligible Retirement Date" shall mean, with respect to any Independent
Board Member, the later of (i) January 1, 1993, (ii) the first day of the
calendar month following the month in which such Independent Board Member's
seventy-second birthday occurs, or (iii) such later date as the Board may
establish as his or her "Eligible Retirement Date."

     (e) "Retirement" shall mean any termination of service of an Independent
Board Member except any termination which the Board determines to have resulted
from the Independent Board Member's willful misfeasance, bad faith, gross
negligence or reckless disregard of the duties involved in the conduct of the
office of Independent Board Member.

     (f) "Benefit" shall mean with respect to any Eligible Board Member, (i)
the Regular Benefit, unless the Alternate Benefit has been elected or the Early
Benefit granted, (ii) the Alternate Benefit, if elected by such Eligible Board
Member, unless the Early Benefit has been granted, or (iii) the Early Benefit,
if granted by the Board.

     (g) "Eligible Compensation" shall mean, with respect to any Eligible Board
Member of any Adopting Fund, an amount equal to one-fifth of the total
compensation, inclusive of compensation as a member of the Board or of a Board
Committee or as chairperson of a Board Committee, earned by such Eligible Board
Member for Eligible Service with respect to such Adopting Fund (other than
under this Plan) in the five year period prior to the date of his or her
Retirement.

     (h) "Actuarial Equivalent" shall mean an actuarially equivalent benefit,
as computed by the Board with the advice of an enrolled actuary (as defined in
the Employee Retirement Income Security Act of 1974, as amended ["ERISA"]),
using assumptions determined by the Board at the time of the computation.

     (i) "Board" shall mean, with respect to any Adopting Fund, the Board of
Directors or Trustee or "directors," (as such term is defined in Section
2(a)(12) of the Act, of such Adopting Fund.

     (j) "Adoption Date" shall mean February 21, 1991.

<PAGE>

     2. ELIGIBILITY

     Each Eligible Board Member will be eligible to receive a Benefit from each
Adopting Fund commencing on such Eligible Board Member's Eligible Retirement
Date.

     3. RETIREMENT DATE; AMOUNT OF BENEFIT

     (a) Retirement. Each Independent Board Member will retire not later than
his or her Eligible Retirement Date. The foregoing provision shall be deemed by
the adoption of this Plan by any Fund to be an amendment of such Fund's by-laws
superseding any provision therein that an Independent Board Member shall serve
until his or her successor shall have been elected and qualified.
Notwithstanding the foregoing, the Board of any Adopting Fund may, to avoid the
simultaneous retirement of more than one of the Independent Board Members or
for any other appropriate reason, waive the obligation of any Independent Board
Member to retire on such date and may establish a later date as his or her
"Eligible Retirement Date." Any establishment of an Eligible Retirement Date
may be further extended by the Board.

     (b) Regular Retirement Benefit. Upon Retirement, each Eligible Board
Member will receive, commencing as of such Eligible Board Member's Eligible
Retirement Date and continuing for the remainder of the Eligible Board Member's
life, from each Adopting Fund a retirement benefit (the "Regular Benefit") paid
at an annual rate equal to the percentage of his or her Eligible Compensation
established by resolution of the Board of such Adopting Fund most recently
adopted prior to the date of his or her retirement (the "Most Recent
Resolution") as the "Minimum Percentage," PLUS an additional percentage of such
Eligible Compensation for each full month of Eligible Service for any of the
Adopting Funds in excess of five years established by the Most Recent
Resolution as the "Monthly Additional Percentage," up to the percentage
established by the Most Recent Resolution as the "Maximum Percentage" of such
Eligible Compensation for ten or more years of Eligible Service for any of the
Adopting Funds.

     (c) Election of Alternate Payment of Benefit. Each Independent Board
Member shall have the option, exercisable at any time, and revisable at any
time and from time to time, prior to his or her first acceptance of benefits
under the Plan to elect (i) to receive, subject to being or becoming an
Eligible Board Member, a retirement benefit (the "Alternate Benefit") based
upon the combined life expectancy of such Eligible Board Member and his or her
spouse on the date of such Eligible Board Member's Retirement (rather than
solely upon such Eligible Board Member's own life, as shall be the case unless
such Eligible Board Member shall otherwise elect as provided in this Section
3(c)), and (ii) if the Independent Board Member elects to receive the Alternate
Benefit, to elect a benefit either (x) to the last survivor of the Eligible
Board Member or spouse, whether the Eligible Board Member or spouse is the last
survivor (a "joint and last survivor" benefit) or (y) to the Eligible Board
Member's spouse if the spouse survives the Eligible Board Member (a "joint and
contingent survivor" benefit) equal in periodic amount to a percentage (the
"Designated Survivor's Percentage") of the periodic amount that would be, or
would be assumed to be, in effect while both the Eligible Board Member and
spouse were alive. The Designated Survivor's Percentage shall be the percentage
stated in the most recently delivered notice of election given by such
Independent Board Member, or, if no percentage is stated in any such notice,
100%. Payment of the Alternate Benefit shall commence on the later of such
Eligible Board Member's Eligible Retirement Date or the date of his or her
Retirement, shall be reduced to the Designated Survivor's Percentage (if less
than 100%) upon the earlier of the deceases of the Eligible Board Member and
spouse in the case of a joint and last survivor benefit, or of the Eligible
Board Member in the case of a joint and contingent survivor benefit, and shall
be payable through the remainder of the life of the survivor of such Eligible
Board Member and spouse. The Alternate Benefit shall be the Actuarial
Equivalent of the Regular Benefit provided under paragraph 3(b). In the event
of the death of an Eligible Board Member who has chosen the Alternate Benefit
prior to such Eligible Board Member's Retirement, his or her spouse shall be
entitled to a retirement benefit, commencing upon such death, which shall be
the Actuarial Equivalent of the benefit such spouse would have received had
such Eligible Board Member died on his or her Eligible Retirement Date.

                                        2

     (d) Early Payment of Benefit. An Eligible Board Member for good cause may
apply to the Board of any Adopting Fund for, and, at the discretion of such
Board, may be granted, a retirement benefit (the "Early Benefit") which is the
Actuarial Equivalent of the Regular Benefit or Alternate Benefit previously
elected by such Eligible Board Member. Payment of the Early Benefit shall
commence on a date fixed by the Board in its sole discretion as such Eligible
Board Member's Eligible Retirement Date and shall be payable through the
remainder of such Eligible Board Member's life, or, if the Alternate Benefit
had been elected, the later of the lives of such Eligible Board Member and
spouse. Good cause for these purposes may include (but is not limited to) the
permanent disability of the Eligible Board Member.

     (e) Anything contained herein to the contrary notwithstanding, upon the
adoption by an Adopting Fund of a plan of liquidation, such Adopting Fund shall
pay to each Eligible Board Member who has retired, in lieu of his or her
Benefit from such Adopting Fund, an amount (the "Lump Sum") equal to the then
present value of the Benefit, using a discount rate determined by the Board at
the time of the computation. The Lump Sum shall be paid by such Adopting Fund
at or before the final liquidation and dissolution of such Adopting Fund.

     4. TIME OF PAYMENT

     The Benefit to each Eligible Board Member or his or her spouse will,
except as provided in Section 3(c), 3(d) or 3(e) hereof, commence on such
Eligible Board Member's Eligible Retirement Date and will be paid each year in
quarterly installments that are as nearly equal as possible on the first day of
each calendar quarter.

     5. PAYMENT OF BENEFIT; ALLOCATION OF COSTS

     Each Adopting Fund is responsible for the payment of Benefits based upon
Eligible Compensation from such Adopting Fund, as well as its proportionate
share of all expenses of administration of the Plan, including without
limitation all accounting and legal fees and expenses and fees and expenses of
any enrolled actuary. The obligations of each Adopting Fund to pay such
benefits and expenses will not be secured or funded in any manner, and such
obligations will not have any preference over the lawful claims of the Adopting
Funds' creditors and stockholders, shareholders, beneficiaries or limited
partners, as the case may be. To the extent that an Adopting Fund consists of
one or more separate portfolios, such costs and expenses will be allocated
among such portfolios in the proportion that compensation of Independent Board
Members is allocated among such portfolios.

     6. ADMINISTRATION

     (a) Administration. Any question involving entitlement to payments under
or the administration of the Plan will be referred to the Board, which shall
make all interpretations and determinations necessary or desirable for the
Plan's administration (such interpretations and determinations to be final and
conclusive) and shall cause such records to be kept as may be necessary for the
administration of the Plan.

     7. MISCELLANEOUS

     (a) Rights Not Assignable. The right to receive any payment under the Plan
is not transferable or assignable. Except as otherwise provided herein with
respect to the Alternate Benefit, the Plan shall not create any benefit, cause
of action, right of sale, transfer, assignment, pledge, encumbrance, or other
such right in any spouse or heirs or the estate of any Eligible Board Member or
retired Eligible Board Member.

     (b) Amendment, etc. With respect to each Adopting Fund, the Board,
including a majority of the Independent Board Members of such Board, may at any
time amend or terminate the Plan or waive any provision of the Plan, PROVIDED,
that except as otherwise provided herein, no amendment, termination or waiver
will impair the rights of an Independent Board Member to receive upon
Retirement the payments which would have been made to such Independent Board
Member had there been no such amendment, termination or waiver (based upon such
Board Member's Eligible Service to the date of such amendment, termination or
waiver) or the rights of a retired Eligible Board Member to receive any Benefit
due under the Plan, without the consent of such Independent Board Member or
Eligible Board Member. Notwithstanding any provision to the contrary, the
Board, with the concurrence of a majority of the Independent Board Members of
such Board and without the consent of any individual Independent

                                        3
<PAGE>

Board Member, may at any time (i) amend or terminate the Plan to comply with
any applicable provision of law or any rule or regulation adopted, or proposed
to be adopted, by any governmental agency or any decision of any court or
administrative agency, (ii) change any assumptions used to determine what
benefit may be an Actuarial Equivalent, or (iii) terminate the Plan of an
Adopting Fund (an "Acquired Adopting Fund") substantially all the assets of
which are acquired by an entity which is itself an Adopting Fund (the
"Acquiring Adopting Fund") pursuant to a plan of reorganization between the
Acquired Adopting Fund and the Acquiring Adopting Fund (the "Reorganization
Plan"), such termination to be deemed approved upon adoption of the
Reorganization Plan and to be effective upon the effectiveness of the
reorganization contemplated thereby without liability or further obligation for
any benefits accrued or otherwise payable to an Independent Board Member by the
Acquired Adopting Fund.

     (c) No Right to Reelection. Nothing in the Plan will create any obligation
on the part of the Board to nominate any Independent Board Member for
reelection.

     (d) Vacancies. Although the Board will retain the right to increase or
decrease its size, it shall be the general policy to replace each retired
Independent Board Member by selecting a new Independent Board Member from
candidates recommended by the remaining Independent Board Members.

     (e) Consulting. Each retired Eligible Board Member may render such
services for any of the Adopting Funds, for such compensation, as may be agreed
upon from time to time by such retired Eligible Board Member and the Board.

     (f) Effectiveness. The Plan will be effective for all Independent Board
Members who have dates of Retirement occurring on or after the Adoption Date.
Periods of Eligible Service shall include periods commencing prior to such
date.

Dean Witter Short-Term U.S. Treasury Trust
Two World Trade Center
New York, New York 10048

Dear Sirs:

     With respect to the Registration Statement on Form N-1A (File No. 33-41187)
(the "Registration Statement") filed by Dean Witter Short-Term U.S. Treasury
Trust, a Massachusetts business trust (the "Fund"), with the Securities and
Exchange Commision for the purpose of registering under the Securities Act of
1933, as amended, an indefinite number of shares of Beneficial Interest of $0.01
par value of the Fund (the "Shares"), I, as your counsel, have examined such
Fund records, certificates and other documents and reviewed such questions of
law as I have considered necessary or appropriate for the purposes of this
opinion, and on the basis of such examination and review, I advise you that, in
my opinion, proper trust proceedings have been taken by the Fund so that the
Shares have been validly authorized; and when the Shares have been issued and
sold in accordance with the terms of the Underwriting Agreement referred to in
the Registration Statement, the Shares will be validly issued, fully paid and
non-assessable.

     As to matters of Massachusetts law contained in the foregoing opinion, I
have relied upon the opinion of Gaston & Snow, dated July 25, 1991.

     I hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to me under the caption "Validity
of Shares of Beneficial Interest" in the Statement of Additional Information
forming a part of the Registration Statement. In giving this consent, I do not
thereby admit that I am within the category of persons whose consent is required
under Section 7 of the Securities Act of 1933, as amended, or the rules and
regulations of the Securities and Exchange Commission thereunder.

                                            Very truly yours,

                                            /s/ Sheldon Curtis

Dean Witter Short-Term U.S.
  Treasury Trust
Two World Trade Center
New York, NY 10048

Gentlemen:

     Dean Witter Short-Term U.S. Treasury Trust (the "Trust") is a trust created
under a written Declaration of Trust executed in Boston, Massachusetts on
June 3, 1991 (the "Trust Agreement"). The Trustees have the powers set forth in
the Trust Agreement, subject to the terms, provisions and conditions therein
provided. We have acted as special Massachusetts counsel for the Trust with
respect to the organization of the Trust, and in such capacity we are furnishing
you with this opinion.

     We have examined originals or copies, certified or otherwise identified to
our satisfaction, of such certificates, records and other documents as we have
deemed necessary or appropriate for the purpose of this opinion, including the
Trust Agreement. The Trust Agreement has been duly filed with the Secretary of
The Commonwealth of Massachusetts and the City Clerk of the City of Boston. All
filing requirements under the laws of Massachusetts have been complied with
(other than the requirements of the Massachusetts Uniform Securities Act).

     Under Article VI, Section 6.1 of the Trust Agreement, the beneficial
interest in the Trust is represented by an unlimited number of transferable
shares, $.01 par value. Under Article VI, Section 6.4, the Trustees are
empowered in their discretion to issue shares of beneficial interest to such
party or parties and for such amount and type of consideration, including cash
or property, at such time or times and on such terms as the Trustees may deem
best.

     Based upon the foregoing, and with respect to Massachusetts law (other than
the Massachusetts Uniform Securities Act), only to the extent that Massachusetts
law may be applicable and without reference to the laws of the other several
states or of the United States of America, we are of the opinion that, under
existing law:

     (1) The Trust is a trust with transferable shares of beneficial interest,
organized in compliance with the laws of The Commonwealth of Massachusetts, and
the Trust Agreement is legal and valid.

     (2) Shares of beneficial interest which are registered under the Securities
Act of 1933, as amended, under a registration statement on Form N-1A (File No.
33-41187) which the Trust has filed with the Securities and Exchange Commission
(the "Registration Statement"), may be legally and validly issued pursuant to
votes adopted by the Trustees of the Trust upon receipt by the Trust of payment
in compliance with Article VI, Section 6.4 of the Trust Agreement. We are
further of the opinion that such shares when so issued will be fully paid and
nonassessable by the Trust.

     We understand that Sheldon Curtis, Esq., General Counsel for the Trust will
rely on this opinion in connection with his opinion to be filed with the
Securities and Exchange Commission as an exhibit to the Registration Statement.
We hereby consent to such use of this opinion.

                                       Very truly yours,

                                       /s/ Gaston & Snow
