FEE                0.35% of daily net assets (see page 5).

DISTRIBUTIONS      for reinvestment by the Fund. Dividends and capital gains distributions

AND PLAN OF        Fund is authorized to reimburse specific expenses incurred in promoting 
DISTRIBUTION       the distribution of the Fund's shares, including personal services 
                   to shareholders and maintenance of shareholders accounts, in accordance 
                   with a Plan of Distribution with the Distributor pursuant to Rule 
                   12b-1 under the Investment Company Act of 1940. Reimbursement may 
                   in no event exceed an amount equal to payments at an annual rate of 
                   0.35% of average daily net assets of the Fund (see page 7). 
- ------------------ ---------------------------------------------------------------- 
REDEMPTION         At net asset value; account may be involuntarily redeemed if total 
                   value of the account is less than $1,000 or, if the account was opened 
                   through EasyInvest (Service Mark), if after twelve months the

RISKS              The Fund invests only in U.S. Treasury securities which are subject 
                   to minimal risk of loss of income and principal. It may engage in 
                   the purchase of such securities on a when-issued basis. The value 
                   of the Fund's portfolio securities, and therefore the Fund's net asset 
                   value per share, may increase or decrease due to various factors, 
                   principally changes in prevailing interest rates. Generally, a rise 
                   in interest rates will result in a decrease in the Fund's net asset 
                   value per share, while a drop in interest rates will result in an 
                   increase in the Fund's net asset value per share. A portion of the 
                   U.S. Treasury securities in which the Fund invests may be zero coupon 
                   Treasury securities. Such securities are subject to greater market 
                   price fluctuations during periods of changing prevailing interest 
                   rates (see pages 5-6).

THE FUND AND ITS MANAGEMENT 
- ----------------------------------------------------------------------------- 

Dean Witter Short-Term U.S. Treasury Trust (the "Fund") is an open-end 
diversified management investment company. The Fund is a trust of the type 
commonly known as a "Massachusetts business trust" and was organized under the 
laws of The Commonwealth of Massachusetts on June 4, 1991. 

   Dean Witter InterCapital Inc. ("InterCapital" or the "Investment 
Manager"), whose address is Two World Trade Center, New York, New York 10048, 
is the Fund's Investment Manager. The Investment Manager, which was 
incorporated in July, 1992, is a wholly-owned subsidiary of Morgan Stanley, 
Dean Witter, Discover & 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. 

   InterCapital and its wholly-owned subsidiary, Dean Witter Services 
Company, serve in various investment management, advisory, management and 
administrative capacities to a total of 100 investment companies, thirty of 
which are listed on the New York Stock Exchange, with combined total assets 
of approximately $93.1 billion as of June 30, 1997. The Investment Manager 
also manages portfolios of pension plans, other institutions and individuals 
which aggregated approximately $3.5 billion at such date. 

   The Fund has retained the Investment Manager to provide administrative 
services, manage its business affairs and manage the investment of the Fund's 
assets, including the placing of orders for the purchase and sale of 
portfolio securities. InterCapital has retained Dean Witter Services Company 
Inc. to perform the aforementioned administrative services for the Fund. The 
Fund's Board of Trustees reviews the various services provided by or under 
the direction of the Investment Manager to ensure that the Fund's general 
investment policies and programs are being properly carried out and that 
administrative services are being provided to the Fund in a satisfactory 
manner. 

   As full compensation for the services and facilities furnished to the Fund 
and for expenses of the Fund assumed by the Investment Manager, the Fund pays 
the Investment Manager monthly compensation calculated daily by applying an 
annual rate of 0.35% to the Fund's net assets determined as of the close of 
each business day. For the fiscal year ended May 31, 1997, the Fund accrued 
total compensation to the Investment Manager amounting to 0.35% of the Fund's 
average daily net assets and the Fund's total expenses amounted to 0.83% of 
the Fund's average daily net assets. 

INVESTMENT OBJECTIVE AND POLICIES 
- ----------------------------------------------------------------------------- 

The investment objective of the Fund is current income, preservation of 
principal and liquidity. The Fund will seek to achieve its investment 
objective by investing all of its net assets in U.S. Treasury securities. 
U.S. Treasury securities, which presently consist of U.S. Treasury bills, 
U.S. Treasury notes and U.S. Treasury bonds, are direct obligations of the 
U.S. Treasury and are backed by the "full faith and credit" of the U.S. 
Government. The investment objective is a fundamental policy of the Fund and 
may not be changed without the approval of the holders of a majority of the 
Fund's shares. There is no assurance that the Fund's investment objective 
will be achieved. 

   Neither the value nor the yield of the U.S. Treasury securities in which 
the Fund invests (or the value or yield of shares of the Fund) are guaranteed 
by the U.S. Government. The value of the Fund's portfolio securities and 
therefore the net asset value of the Fund's shares may increase or decrease 
due to changes in prevailing interest rates and other factors. Generally, as 
prevailing interest rates rise, the value of the securities held by the Fund, 
and concomitantly, the net asset value of the Fund's shares, will fall. Debt 
securities with shorter maturities are generally subject to a lesser degree 
of market fluctuation as a result of changes in interest rates than debt 
securities with longer maturities. In an effort to minimize fluctuations in 
market value of its portfolio securities the Fund is expected to maintain a 
portfolio with a dollar-weighted average maturity of less than 3 years. 

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). 

   The interest earned on such 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 

                                5           
<PAGE>
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. Current federal tax law requires that a 
holder (such as the Fund) of a zero coupon security accrue a portion of the 
discount at which the security was purchased as income each year even though 
the Fund receives no interest payments in cash on the security during the 
year. See "Dividends, Distributions and Taxes." 

   Certain banks and brokerage firms have separated ("stripped") the 
principal portions ("corpus") from the coupon portions of the U.S. Treasury 
bonds and notes and sell them separately in the form of receipts or 
certificates representing undivided interests in these instruments (which 
instruments are generally held by a bank in a custodial or trust account). 
The Fund will not purchase any such receipts or certificates representing 
stripped corpus or coupon interests in U.S. Treasury securities sold by banks 
and brokerage firms. The Fund will only purchase zero coupon Treasury 
securities which have been stripped by the Federal Reserve Bank. 

WHEN-ISSUED AND DELAYED DELIVERY SECURITIES AND FIRM COMMITMENTS. From time 
to time, in the ordinary course of business, 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 a month or more of 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. 

PORTFOLIO MANAGEMENT 

The Fund's portfolio is actively managed by its Investment Manager with a 
view to achieving the Fund's investment objective. In determining which 
securities to purchase for the Fund or hold in the Fund's portfolio, the 
Investment Manager will rely on information from various sources, including 
research, analysis and appraisals of brokers and dealers, including Dean 
Witter Reynolds Inc. ("DWR") and other broker-dealer affiliates of 
InterCapital, and others regarding economic developments and interest rate 
trends, and the Investment Manager's own analysis of factors it deems 
relevant. The Fund's portfolio is managed within InterCapital's Taxable Fixed 
Income Group, which manages 24 funds and fund portfolios, with approximately 
$12.8 billion in assets as of June 30, 1997. Rajesh K. Gupta, Senior Vice 
President of InterCapital and Manager of InterCapital's Government 
Fixed-Income Group, has been the primary portfolio manager of the Fund since 
its inception and has been a portfolio manager at InterCapital for over five 
years. 

   Brokerage commissions are not normally charged on the purchase or sale of 
U.S. Government obligations, but such transactions may involve costs in the 
form of spreads between bid and asked prices. Pursuant to an order of the 
Securities and Exchange Commission, the Fund may effect principal 
transactions in certain money market instruments with DWR. In addition, the 
Fund may incur brokerage commissions on transactions conducted through DWR 
and other brokers and dealers that are affiliates of InterCapital. Although 
the Fund does not intend to engage in short-term trading of portfolio 
securities as a means of achieving its investment objective, it may sell 
portfolio securities without regard to the length of time they have been held 
whenever such sale will, in the opinion of the Investment Manager, strengthen 
the Fund's position and contribute to its investment objective. It is not 
anticipated that the portfolio trading engaged in by the Fund will result in 
its portfolio turnover rate exceeding 200% in any one year. The Fund will 
incur costs commensurate with its portfolio turnover rate. Short term gains 
and losses may result from such transactions. See "Dividends, Distributions 
and Taxes" for a full discussion of the tax implications of the Fund's 
trading policy.

PURCHASE OF FUND SHARES 
- ----------------------------------------------------------------------------- 

The Fund offers its shares for sale to the public on a continuous basis. 
Pursuant to a Distribution Agreement between the Fund and Dean Witter 
Distributors Inc. (the "Distributor"), an affiliate of the Investment 
Manager, shares of the Fund are distributed by the Distributor and offered by 
DWR and others who have entered into Selected Dealer agreements with the 
Distributor ("Selected Broker-Dealers"). The principal executive office of 
the Distributor is located at Two World Trade Center, New York, New York 
10048. 

   The minimum initial purchase is $10,000 (the Fund and the Distributor may, 
from time to time accept initial purchases of $5,000). The minimum initial 
purchase in the case of investments through EasyInvest (Service Mark), an 
automatic purchase plan (see "Shareholder Services"), is $1,000, provided 
that the schedule of automatic investments will result in investments 
totalling at least $10,000 within the first twelve months. In the case of 
investments pursuant to systematic payroll deduction plans (including 
Individual Retirement Plans), the Fund, in its discretion, may accept 
investments without regard to any minimum amounts which would otherwise be 
required if the Fund has reason to believe that additional investments will 
increase the investment in all accounts under such plans to at least $1,000. 
Minimum subsequent purchases of $100 or more may be made by sending a check, 
payable to Dean Witter Short-Term U.S. Treasury Trust, directly to Dean 
Witter Trust FSB (the "Transfer Agent") at P.O. Box 1040, Jersey City, NJ 
07303 or by contacting an account executive of DWR or another Selected 
Broker-Dealer. The offering price will be the net asset value per share next 
determined (see "Determination of Net Asset Value" below) following receipt 
and acceptance by the Transfer Agent of an order in proper form and 
accompanied by payment in Federal funds (i.e., monies of member banks within 
the Federal Reserve System held on deposit at a Federal Reserve Bank) 
available to the Fund for investment. Orders for the purchase of Fund shares 
placed by investors through DWR or another Selected Broker-Dealer will be 
transmitted to the Transfer Agent for purchase on that date, with payment in 
Federal funds transmitted to the Transfer Agent on the business day following 
the day the order is placed. Shares commence earning income on the date 
following the date of purchase. Certificates for shares purchased will not be 
issued unless requested by the shareholder in writing to the Transfer Agent. 

   Sales personnel of a Selected Broker-Dealer are compensated for shares of 
the Fund sold by them by the Distributor or any of its affiliates and/or by a 
Selected Broker-Dealer. In addition, some sales personnel of the Selected 
Broker-Dealer will receive various types of non-cash compensation as special 
sales incentives, including trips to educational and/or business seminars and 
merchandise. The Fund and the Distributor reserve the right to reject any 
purchase orders. 

DETERMINATION OF NET ASSET VALUE 

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 the 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. 

   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; (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); and (3) 
short-term debt instruments having a maturity date of more than 60 days are 
valued on a "mark-to-market" basis, that is, at prices based on market 
quotations for securities of similar type, yield, quality and maturity, until 
60 days prior to maturity and thereafter at amortized cost. Short-term 
instruments having a maturity date of 60 days or less at the time of purchase 
are valued at amortized cost unless the Board of Trustees determines this 
does not represent the securities' market value, in which case these 
securities will be valued at their fair value as determined by the Trustees. 

   Certain of the Fund's portfolio securities may be valued by an outside 
pricing service approved by the Fund's Trustees. The pricing service may 
utilize a matrix system incorporating security quality, maturity and coupon 
as the evaluation model parameters, and/or research and evaluations by its 
staff, including review of broker-dealer market price quotations, in 
determining what it believes is the fair valuation of the portfolio 
securities valued by such pricing service. 

PLAN OF DISTRIBUTION 

The Fund has entered into a Plan of Distribution pursuant to Rule 12b-1 under 
the Investment Company Act of 1940, as amended (the "Act"), with the 
Distributor whereby the expenses of certain activities and services, 
including personal services to shareholders and 

                                7           
<PAGE>
maintenance of shareholder accounts, in connection with the distribution of 
the Fund's shares are reimbursed. The principal activities and services which 
may be provided by the Distributor and its affiliates, or any other Selected 
Broker-Dealer under the Plan include: (1) compensation to, and expenses of, 
DWR account executives and others, 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. 
Reim bursements for these services will be made in monthly payments by the 
Fund, which will 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. A portion of the 
amount payable pursuant to the Plan, which may not exceed 0.25% of the Fund's 
average daily net assets, is characterized as a service fee within the 
meaning of the NASD guidelines. The services fee is a payment made for 
personal services and/or the maintenance of shareholder accounts. Expenses 
incurred pursuant to the Plan in any fiscal year will not be reimbursed by 
the Fund through payments accrued in any subsequent fiscal year. The Fund 
accrued $890,492 to the Distributor pursuant to the Plan for the fiscal year 
ended May 31, 1997. This is an accrual at the annual rate of 0.35% of the 
Fund's average daily net assets. 

SHAREHOLDER SERVICES 
- ----------------------------------------------------------------------------- 

AUTOMATIC INVESTMENT OF DIVIDENDS AND DISTRIBUTIONS. All income dividends and 
capital gains distributions are automatically paid in full and fractional 
shares of the Fund, unless the shareholder requests that they be paid in cash. 
Such dividends and distributions will be paid in shares of the Fund at net 
asset value per share. At any time an investor may request the Transfer Agent 
in writing to have subsequent dividends and/or capital gains distributions 
paid to the investor in cash rather than shares. To assure sufficient time to 
process the change, such request should be received by the Transfer Agent at 
least five business days prior to the payment date for which it commences to 
take effect. In the case of recently purchased shares for which registration 
instructions have not been received on the record date, cash payments will be 
made to DWR or other Selected Broker-Dealer through whom shares were purchased.

INVESTMENT OF DISTRIBUTIONS RECEIVED IN CASH.  Any shareholder who receives a 
cash payment representing a dividend or capital gains distribution may invest 
such dividend or distribution at the net asset value next determined after 
receipt by the Transfer Agent by returning the check or the proceeds to the 
Transfer Agent within 30 days after the payment date. 

TARGETED DIVIDENDS(SERVICE MARK). In states where it is legally permissible, 
shareholders may also have all income dividends and capital gains 
distributions automatically invested in shares of an open-end investment 
company for which InterCapital serves as investment manager (collectively, 
the "Dean Witter Funds"), other than Dean Witter Short-Term U.S. Treasury 
Trust. Such investment will be made as described above for automatic 
investment in shares of the Fund, at the net asset value per share of the 
selected Dean Witter Fund as of the close of business on the payment date and 
will begin to earn dividends, if any, in the selected Dean Witter Fund the 
next business day. To participate in the Targeted Dividends program, 
shareholders should contact their DWR or other Selected Broker-Dealer account 
executive or the Transfer Agent. Shareholders of the Fund must be 
shareholders of the selected Class of the Dean Witter Fund targeted to 
receive investments from dividends at the time they enter the Targeted 
Dividends program. Investors should review the prospectus of the targeted 
Dean Witter Fund before entering the program. 

EASYINVEST(SERVICE MARK). Shareholders may subscribe to EasyInvest, an 
automatic purchase plan which provides for any amount from $100 to $5,000 to 
be transferred automatically from a checking or savings account, on a 
semi-monthly, monthly or quarterly basis, to the Fund's Transfer Agent for 
investment in shares of the Fund (see "Purchase of Fund Shares" and 
"Redemptions and Repurchases--Involuntary Redemption"). Shares pur chased 
through EasyInvest will be added to the shareholder's existing account at the 
net asset value calculated the same business day the transfer of funds is 
effected. For further information or to subscribe to EasyInvest, shareholders 
should contact their DWR or other Selected Broker-Dealer account executive or 
the Transfer Agent. 

SYSTEMATIC WITHDRAWAL PLAN. A systematic withdrawal plan (the "Withdrawal 
Plan") is available for shareholders who own or purchase shares of the Fund 
having a minimum value of $10,000 based upon the then current offering price. 
The Withdrawal Plan provides for monthly or quarterly (March, June, September 
and December) checks in any dollar amount, not less than $25, or in any whole 
percentage of the account balance, on an annualized basis. The shares will be 
redeemed at their net asset value determined, at the shareholder's option, on 
the tenth or twenty-fifth day (or next following business day) of the 
relevant month or quarter and normally a check for the proceeds will be 
mailed by the Transfer Agent, or amounts credited to a shareholder's DWR or 
other Selected Broker-Dealer brokerage account, within five business days 
after the date of redemption. Only 

                                8           
<PAGE>
shareholders having accounts in which no share certificates have been issued 
will be permitted to enroll in the Withdrawal Plan. 

   Withdrawal Plan payments should not be considered as dividends, yields or 
income. If periodic withdrawal plan payments continuously exceed net 
investment income and net capital gains, the shareholder's original 
investment will be correspondingly reduced and ultimately exhausted. 

   Each withdrawal constitutes a redemption of shares and any gain or loss 
realized must be recognized for federal income, and generally, state and 
local tax purposes. 

   Shareholders wishing to enroll in the Withdrawal Plan should make this 
election on the Investment Application or contact their DWR or other Selected 
Broker-Dealer account executive or the Transfer Agent. 

TAX SHELTERED RETIREMENT PLANS. Retirement plans are available through the 
Investment Manager for use by the self-employed, eligible Individual 
Retirement Accounts and Custodial Accounts under Section 403(b)(7) of the 
Internal Revenue Code. Adoption of such plans should be on advice of legal 
counsel or tax adviser. 

   For further information regarding plan administration, custodial fees and 
other details, investors should contact their account executive or the 
Transfer Agent. 

EXCHANGE PRIVILEGE 

An "Exchange Privilege," that is, the privilege of exchanging shares of 
certain Dean Witter Funds for shares of the Fund, exists whereby shares of 
Dean Witter Funds that are multiple class funds ("Dean Witter Multi-Class 
Funds") and Dean Witter Funds that are not multiple class funds but which are 
sold with either a front-end (at time of purchase) sales charge ("FSC funds") 
or a contingent deferred (at time of redemption) sales charge ("CDSC funds"), 
may be exchanged for shares of the Fund, Dean Witter Intermediate Term U.S. 
Treasury Trust, Dean Witter Limited Term Municipal Trust and Dean Witter 
Short-Term Bond Fund, and for shares of five Dean Witter Funds which are 
money market funds: Dean Witter Liquid Asset Fund Inc., Dean Witter U.S. 
Government Money Market Trust, Dean Witter Tax-Free Daily Income Trust, Dean 
Witter California Tax Free Daily Income Trust and Dean Witter New York 
Municipal Money Market Trust (which nine funds, including the Fund, are 
hereinafter collectively referred to as "Exchange Funds"). Shares of the 
Exchange Funds received in an exchange for shares of a Dean Witter 
Multi-Class Fund may be redeemed and exchanged only for shares of the 
corresponding Class of a Dean Witter Multi-Class Fund or for shares of one of 
the other Exchange Funds, provided that shares of the Exchange Funds received 
in an exchange for Class A shares of a Dean Witter Multi-Class Fund may also 
be redeemed and exchanged for shares of a FSC fund, and shares of the 
Exchange Funds received in an exchange for Class B shares of a Dean Witter 
Multi-Class Fund may also be redeemed and exchanged for shares of a CDSC 
fund. In addition, shares of the Exchange Funds received in an exchange for 
shares of a FSC fund may be redeemed and exchanged for Class A shares of a 
Dean Witter Multi-Class Fund or for shares of one of the other Exchange 
Funds, and shares of the Exchange Funds received in an exchange for shares of 
a CDSC fund may be redeemed and exchanged for Class B shares of a Dean Witter 
Multi-Class Fund or for shares of one of the other Exchange Funds. 

   An exchange to an Exchange Fund that is not a money market fund is on the 
basis of the next calculated net asset value per share of each fund after the 
exchange order is received. When exchanging into a money market fund, shares 
of the Multi-Class Fund, the FSC fund, the CDSC fund or the Exchange Fund are 
redeemed at their next calculated net asset value and exchanged for shares of 
the money market fund at their net asset value determined the following 
business day. Ultimately, any applicable contingent deferred sales charge 
("CDSC") will have to be paid upon redemption of shares originally purchased 
from a CDSC fund or a Class of a Dean Witter Multi-Class Fund that imposes a 
CDSC. (If shares of an Exchange Fund received in exchange for shares 
originally purchased from a CDSC fund or Class B of a Dean Witter Multi-Class 
Fund are exchanged for shares of another CDSC fund or a Dean Witter 
Multi-Class Fund having a different CDSC schedule than that of the CDSC fund 
or the Dean Witter Multi-Class Fund from which the Exchange Fund shares were 
acquired, the shares will be subject to the higher CDSC schedule.) During the 
period of time the shares originally purchased from a CDSC fund or from a 
Class of a Dean Witter Multi-Class Fund that imposes a CDSC remain in the 
Exchange Fund, the holding period (for the purpose of determining the rate of 
CDSC) is frozen. If those shares are subsequently re-exchanged for shares of 
a CDSC fund or a Dean Witter Multi-Class Fund, the holding period previously 
frozen when the first exchange was made resumes on the last day of the month 
in which shares of a CDSC fund or shares of a Dean Witter Multi-Class Fund 
are reacquired. Thus, the CDSC is based upon the time (calculated as 
described above) the shareholder was invested in shares of a CDSC fund or in 
shares of a Dean Witter Multi-Class Fund. In the case of exchanges of Class A 
shares of a Dean Witter Multi-Class Fund which are subject to a CDSC, the 
holding period also includes the time (calculated as described above) the 
shareholder was invested in shares of a FSC fund. In the case of shares 
exchanged into an Exchange Fund on or after April 23, 1990, upon a redemption 
of shares which results in a CDSC being imposed, a credit (not to exceed the 
amount of the CDSC) will be given in an amount equal to the Exchange Fund 
12b-1 fees, if any, incurred on or after that date which are attributable to 
those shares (see "Purchase of Fund Shares--Plan of Distribution" in the 
respective Exchange Fund Prospectus for a description 

                                9           
<PAGE>
of Exchange Fund distribution fees). Exchanges may be made after the shares 
of the fund acquired by purchase (not by exchange or dividend reinvestment) 
have been held for thirty days. There is no waiting period for exchanges of 
shares acquired by exchange or dividend reinvestment. 

ADDITIONAL INFORMATION REGARDING EXCHANGES. Purchases and exchanges should be 
made for investment purposes only. A pattern of frequent exchanges may be 
deemed by the Distributor to be abusive and contrary to the best interests of 
the Fund's other shareholders and, at the Distributor's discretion, may be 
limited by the Fund's refusal to accept additional purchases and/or exchanges 
from the investor. Although the Fund does not have any specific definition of 
what constitutes a pattern of frequent exchanges, and will consider all 
relevant factors in determining whether a particular situation is abusive and 
contrary to the best interests of the Fund and its other shareholders, 
investors should be aware that the Fund and each of the other Dean Witter 
Funds may in their discretion limit or otherwise restrict the number of times 
this Exchange Privilege may be exercised by any investor. Any such 
restriction will be made by the Fund on a prospective basis only, upon notice 
to the shareholder not later than ten days following such shareholder's most 
recent exchange. 

   The Exchange Privilege may be terminated or revised at any time by the 
Fund and/or any of such Dean Witter Funds for which shares of the Fund may be 
exchanged, upon such notice as may be required by applicable regulatory 
agencies (presently sixty days' prior written notice for termination or 
material revision), provided that six months' prior written notice of 
termination will be given to the shareholders who hold shares of the Exchange 
Funds pursuant to this Exchange Privilege, and provided further that the 
Exchange Privilege may be terminated or materially revised without notice 
under certain unusual circumstances. Shareholders maintaining margin accounts 
with DWR or another Selected Broker-Dealer are referred to their account 
executive regarding restrictions on exchange of shares of the Fund pledged in 
their margin account. 

   The current prospectus for each fund describes its investment objective(s) 
and policies, and shareholders should obtain one and read it carefully before 
investing. Exchanges are subject to the minimum investment requirement of 
each Class of shares and any other conditions imposed by each fund. In the 
case of any shareholder holding a share certificate or certificates, no 
exchanges may be made until all applicable share certificates have been 
received by the Transfer Agent and deposited in the shareholder's account. An 
exchange will be treated for federal income tax purposes the same as a 
repurchase or redemption of shares, on which the shareholder may realize a 
capital gain or loss. However, the ability to deduct capital losses on an 
exchange may be limited in situations where there is an exchange of shares 
within ninety days after the shares are purchased. The Exchange Privilege is 
only available in states where an exchange may legally be made. 

   If DWR or another Selected Broker-Dealer is the current broker-dealer of 
record and its account numbers are part of the account information, 
shareholders may initiate an exchange of shares of the Fund for shares of any 
of the above Dean Witter Funds pursuant to this Exchange Privilege by 
contacting their DWR or other Selected Broker-Dealer account executive (no 
Exchange Privilege Authorization Form is required). Other shareholders (and 
those shareholders who are clients of DWR or another Selected Broker-Dealer 
but who wish to make exchanges directly by writing or telephoning the 
Transfer Agent) must complete and forward to the Transfer Agent an Exchange 
Privilege Authorization Form, copies of which may be obtained from the 
Transfer Agent, to initiate an exchange. If the Authorization Form is used, 
exchanges may be made by contacting the Transfer Agent at (800) 869-NEWS 
(toll-free). 

   The Fund will employ reasonable procedures to confirm that exchange 
instructions communicated over the telephone are genuine. Such procedures 
include requiring various forms of personal identification such as name, 
mailing address, social security or other tax identification number and DWR 
or other Selected Broker-Dealer account number (if any). Telephone 
instructions will also be recorded. If such procedures are not employed, the 
Fund may be liable for any losses due to unauthorized or fraudulent 
instructions. 

   Telephone exchange instructions will be accepted if received by the 
Transfer Agent between 9:00 a.m. and 4:00 p.m. New York time, on any day the 
New York Stock Exchange is open. Any shareholder wishing to make an exchange 
who has previously filed an Exchange Privilege Authorization Form and who is 
unable to reach the Fund by telephone should contact his or her DWR or other 
Selected Broker-Dealer account executive, if appropriate, or make a written 
exchange request. Shareholders are advised that 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 
experience of the Dean Witter Funds in the past. 

   For further information regarding the Exchange Privilege, shareholders 
should contact their DWR or other Selected Broker-Dealer account executive or 
the Transfer Agent.

REDEMPTIONS AND REPURCHASES 
- ----------------------------------------------------------------------------- 

REDEMPTIONS. Shares of the Fund may be redeemed through the Transfer Agent 
(without redemption or other charge) on any day that the New York Stock 
Exchange is open (see "Purchase of Fund Shares--Determination of Net Asset 
Value"). Redemptions will be effected at the net asset value per share next 
determined after the receipt of a redemption request meeting the applicable 
requirements described below. 

1. BY CHECK 

The Transfer Agent will supply blank checks to any shareholder who has 
requested them on an Investment Application. The shareholder may make checks 
payable to the order of anyone in any amount not less than $500 (checks 
written in amounts under $500 will not be honored by the Transfer Agent). 
Shareholders must sign checks exactly as their shares are registered. If the 
account is a joint account, the check may contain one signature unless the 
joint owners have specifically specified on an Investment Application that 
all owners are required to sign checks. Only shareholders having accounts in 
which no share certificates have been issued will be permitted to redeem 
shares by check or enroll in the Systematic Withdrawal Plan. 

   Shares will be redeemed at their net asset value next determined (see 
"Purchase of Fund Shares--Determination of Net Asset Value") after receipt by 
the Transfer Agent of a check which does not exceed the value of the account. 
Payment of the proceeds of a check will normally be made on the next business 
day after receipt by the Transfer Agent of the 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 
receipt of the check used for investment by the Transfer Agent. The Transfer 
Agent will not honor a check in an amount exceeding the value of the account 
at the time the check is presented for payment. Since the dollar value of an 
account is constantly changing, it is not possible for a shareholder to 
determine in advance the total value of its account so as to write a check 
for the redemption of the entire account. For the same reason, a shareholder 
should not write a check for substantially all of the current value of the 
shares in its account with the Fund. 

2. BY TELEPHONE OR WIRE INSTRUCTIONS WITH PAYMENT TO PREDESIGNATED BANK 
   ACCOUNT 

A shareholder may redeem shares by telephoning or sending wire instructions 
to the Transfer Agent. Payment will be made by the Transfer Agent to the 
shareholder's bank account at any commercial bank designated by the 
shareholder in an Investment Application, by wire if the amount is $1,000 or 
more and the shareholder so requests, and otherwise by mail. Normally, the 
Transfer Agent will transmit payment the next business day following receipt 
of a request for redemption in proper form. Only shareholders having accounts 
in which no share certificates have been issued will be permitted to redeem 
shares by wire instructions. 

   DWR and any other participating Selected Broker-Dealers have informed the 
Distributor and the Fund that, on behalf of and as agent for their customers 
who are shareholders of the Fund, they will transmit to the Fund requests for 
redemption of shares owned by their customers. In such cases, the Transfer 
Agent will wire proceeds of redemptions to DWR's or other Selected 
Broker-Dealer's bank account for credit to the shareholders' accounts the 
following business day. DWR and other participating Selected Broker-Dealers 
have also informed the Distributor and the Fund that they do not charge for 
this service. 

   Redemption instructions must include the shareholder's name and account 
number and be wired or called to the Transfer Agent at 800-869-NEWS 
(toll-free). 

3. BY MAIL 

A shareholder may redeem shares by sending a letter to Dean Witter Trust FSB, 
P.O. Box 983, Jersey City, NJ 07303, requesting redemption and surrendering 
share certificates if any have been issued. 

   Redemption proceeds will be mailed to the shareholder at his or her 
registered address or mailed or wired to his or her predesignated bank 
account, as he or she may request. Proceeds of redemption may also be sent to 
some other person, as requested by the shareholder in accordance with the 
general redemption requirements listed below. 

GENERAL REDEMPTION REQUIREMENTS 

Written requests for redemption must be signed by the registered 
shareholder(s). If the proceeds are to be paid to anyone other than the 
registered shareholder(s) or sent to any address other than the shareholder's 
registered address or predesignated bank account, signatures must be 
guaranteed by an eligible guarantor acceptable to the Transfer Agent, 
(shareholders should contact the Transfer Agent for a determination as to 
whether a particular institution is such an eligible guarantor), except in 
the case of redemption by check. Additional documentation may be required 
where shares are held by a corporation, partnership, trust or other 
organization. With regard to shares of the Fund acquired pursuant to the 
Exchange Privilege, any applicable contingent deferred sales charge will be 
imposed upon the redemption of such shares (see "Purchase of Fund 
Shares--Exchange Privilege"). 

   If shares to be redeemed are represented by a share certificate, the 
request for redemption must be 

                               11           
<PAGE>
accompanied by the share certificate and a stock assignment form signed by 
the registered shareholder(s) exactly as the account is registered. 
Signatures must be guaranteed by a commercial bank or member firm of a 
domestic stock exchange. Additional documentation may be required where 
shares are held by a corporation, partnership, trust or other organization. 

   All requests for redemption should be sent to Dean Witter Trust FSB, P.O. 
Box 983, Jersey City, NJ 07303. 

   Generally, the Fund will attempt to make payment for all redemptions 
within one business day, and in no event later than seven days after receipt 
of such redemption request in proper form. However, if the shares being 
redeemed were purchased by check (including a certified or bank cashier's 
check), payment may be delayed for the minimum time needed to verify that the 
check used for investment has been honored (not more than fifteen days from 
the time of receipt of the check by the Transfer Agent). In addition, the 
Fund may postpone redemptions at certain times when normal trading is not 
taking place on the New York Stock Exchange. 

   Whether certificates are held by the shareholder or shares are held in a 
shareholder's account, if the proceeds are to be paid to any person other 
than the record owner, or if the proceeds are to be paid to a corporation 
(other than DWR or any other Selected Broker-Dealer for the account of the 
shareholder), partnership, trust or fiduciary, or sent to the shareholder at 
an address other than the registered address, signature(s) must be guaranteed 
by an eligible guarantor acceptable to the Transfer Agent (shareholders 
should contact the Transfer Agent for a determination as to whether a 
particular institution is such an eligible guarantor). A stock power may be 
obtained from any dealer or commercial bank. 

REPURCHASE.  DWR and other Selected Broker-Dealers are authorized to 
repurchase shares represented by a share certificate which is delivered to 
any of their offices. Shares held in a shareholder's account without a share 
certificate may also be repurchased by DWR and other Selected Broker-Dealers 
upon the telephonic request of the shareholder. The repurchase price is the 
net asset value next determined (see "Purchase of Fund Shares--Determination 
of Net Asset Value") after such repurchase order is received. Payment for 
shares repurchased may be made by the Fund to DWR and other Selected 
Broker-Dealers for the account of the shareholder. The offers by DWR and 
other Selected Broker-Dealers to repurchase shares from shareholders may be 
suspended by them at any time. In that event, shareholders may redeem their 
shares through the Fund's Transfer Agent as set forth above under 
"Redemption." 

PAYMENT FOR SHARES REDEEMED OR REPURCHASED. Payment for shares presented for 
repurchase or redemption will be made by check within seven days after 
receipt by the Transfer Agent of the certificate and/or written request in 
good order. Such payment may be postponed or the right of redemption 
suspended under unusual circumstances. If the shares to be redeemed have 
recently been purchased by check, payment of the redemption proceeds may be 
delayed for the minimum time needed to verify that the check used for 
investment has been honored (not more than fifteen days from the time of 
receipt of the check by the Transfer Agent). Shareholders maintaining margin 
accounts with DWR or other Selected Broker-Dealers are referred to their 
account executive regarding restrictions on redemption of shares of the Fund 
pledged in the margin account. 

REINSTATEMENT PRIVILEGE. A shareholder who has had his or her shares redeemed 
or repurchased and has not previously exercised this reinstatement privilege 
may, within 35 days after the date of the redemption or repurchase, reinstate 
any portion or all of the proceeds of such redemption or repurchase in shares 
of the Fund at net asset value next determined after a reinstatement request, 
together with the proceeds, is received by the Transfer Agent. 

INVOLUNTARY REDEMPTION. The Fund reserves the right to redeem, on 60 days' 
notice and at net asset value, the shares of any shareholder whose shares 
have a value of less than $1,000 as a result of redemptions or repurchases, 
or such lesser amount as may be fixed by the Trustees or, in the case of an 
account opened through EasyInvest (Service Mark), if after twelve months the 
shareholder has invested less than $10,000 in the account. However, before 
the Fund redeems such shares and sends the proceeds to the shareholder, it 
will notify the shareholder that the value of the shares is less than the 
applicable amount and allow him or her 60 days to make an additional 
investment in an amount which will increase the value of his or her account 
to at least the applicable amount or more before the redemption is processed. 

DIVIDENDS, DISTRIBUTIONS AND TAXES 
- ----------------------------------------------------------------------------- 

DIVIDENDS AND DISTRIBUTIONS. The Fund declares dividends from net investment 
income on each day the New York Stock Exchange is open for business. Such 
dividends are payable monthly. The Fund intends to distribute net capital 
gains, if any, at least once each year. The Fund may, however, elect to retain 
all or a portion of any such net long-term capital gains in any year. 

   All dividends and any capital gains distributions will be paid in 
additional Fund shares and automatically credited to the shareholder's 
account without issuance of a share certificate unless the shareholder 
requests in writing that all dividends or all dividends and distributions be 
paid in cash. (See "Shareholder Services--Automatic Investment of Dividends 
and Distributions".) 

                               12

TAXATION 

FEDERAL TAXES. Because the Fund intends to distribute substantially all of 
its net investment income and net short-term capital gains to shareholders 
and otherwise remain qualified as a regulated investment company under 
Subchapter M of the Internal Revenue Code, it is not expected that the Fund 
will be required to pay any federal income tax on such income and capital 
gains. Shareholders will normally have to pay federal income taxes on the 
dividends and capital gains distributions they receive from the Fund. 
Distributions of net investment income and net short-term capital gains are 
taxable to the shareholder as ordinary dividend income regardless of whether 
the shareholder receives such distributions in additional shares or in cash. 
Any dividends declared in the last quarter of any calendar year which are 
paid in the following year prior to February 1 will be deemed received by the 
shareholder in the prior year. 

   Long-term and short-term capital gains may be generated by the sale of 
portfolio securities by the Fund. Distributions of 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. 

   No portion of such distributions will be eligible for the dividends 
received deduction for corporations. To avoid being subject to a 31% federal 
backup withholding tax on taxable dividends, capital gains distributions and 
the proceeds of redemptions and repurchases, shareholders' taxpayer 
identification numbers must be furnished and certified as to accuracy. 

   Current federal law requires that a holder (such as the Fund) of a zero 
coupon security accrue a portion of the discount at which the security was 
purchased as income each year even though the Fund receives no interest 
payments in cash on the security during the year. Accordingly, the Fund may 
be required to pay out as an income distribution each year an amount which is 
greater than the total amount of cash receipts of interest the Fund actually 
received. Such distributions will be made from the available cash of the Fund 
or by liquidation of portfolio securities, if necessary. 

   The Fund may at times make payments from sources other than income or net 
capital gains. Payments from such sources will, in effect, represent a return 
of a portion of each shareholder's investment. All, or a portion, of such 
payments will not be taxable to shareholders. 

   After the end of the year, shareholders will receive full information on 
their dividends and capital gains distributions for tax purposes, including 
information as to the Federal tax status of dividends and distributions paid 
or retained by the Fund. 

   The foregoing discussion relates solely to the Federal income tax 
consequences of an investment in the Fund and dividends (where applicable) 
and distributions may also be subject to state and local taxes (see "State 
and Local Taxes" below); therefore, each shareholder is advised to consult 
his or her own tax adviser. 

STATE AND LOCAL TAXES. The Fund intends to invest only in U.S. Treasury 
obligations that provide interest income exempt from 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 state and local 
taxation. Such investment income, however, will not be exempt from federal 
tax. Furthermore, any capital gains realized by the Fund will not be exempt 
from federal, and generally, 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. Shareholders are urged to consult their tax advisers with 
respect to specific questions regarding federal, state and local taxes. 

PERFORMANCE INFORMATION 
- ----------------------------------------------------------------------------- 

From time to time the Fund may quote its "yield" and/or its "total return" in 
advertisements and sales literature. Both the yield and the total return of 
the Fund are based on historical earnings and are not intended to indicate 
future performance. The yield of the Fund is computed by dividing the net 
investment income of the Fund over a 30-day period by an average value (using 
the average number of shares entitled to receive dividends and the net asset 
value per share at the end of the period), all in accordance with applicable 
regulatory requirements. Such amount is compounded for six months and then 
annualized for a twelve-month period to derive the yield of the Fund. The 
Fund may also quote its tax-equivalent yield, which is calculated by 
determining the pre-tax yield which after being taxed at a stated rate, would 
be equivalent to the yield determined as described above. 

   The "average annual total return" of the Fund refers to a figure 
reflecting the average annualized percentage increase (or decrease) in the 
value of an initial investment in the Fund of $1,000 over periods of one, 
five and ten years or over the life of the Fund, if less than any of the 
foregoing. Average annual total return reflects all income earned by the 
Fund, any appreciation or depreciation of the assets of the Fund, and all 
expenses incurred by the Fund, for the stated periods. It also assumes 
reinvestment of all dividends and distributions paid by the Fund. 

                               13           
<PAGE>

   In addition to the foregoing, the Fund may advertise its total return over 
different periods of time by means of aggregate, average, year-by-year or 
other types of total return figures. The Fund may also advertise the growth 
of hypothetical investments of $10,000, $50,000 and $100,000 in shares of the 
Fund. 

   The Fund from time to time may also advertise its performance relative to 
certain performance rankings and indexes compiled by independent 
organizations (such as Lipper Analytical Services Inc.). 

ADDITIONAL INFORMATION 
- ----------------------------------------------------------------------------- 

VOTING RIGHTS. All shares of beneficial interest of the Fund are of $0.01 par 
value and are equal as to earnings, assets and voting privileges. There are no 
conversion, pre-emptive or other subscription rights. In the event of 
liquidation, each share of beneficial interest of the Fund is entitled to its 
portion of all of the Fund's assets after all debts and expenses have been 
paid. The shares do not have cumulative voting rights. 

   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 Act or the Declaration of Trust. The Trustees 
themselves have the power to alter the number and the terms of office of the 
Trustees and they may at any time lengthen 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. Under certain circumstances the Trustees may be 
removed by action of the Trustees. The shareholders also have the right under 
certain circumstances to remove the Trustees. 

   Under Massachusetts law, shareholders of a business trust may, under 
certain circumstances, be held personally liable as partners for the 
obligations of the Fund. The Declaration of Trust contains an express 
disclaimer of shareholder liability for acts or obligations of the Fund and 
requires that notice of such disclaimer be given in each instrument entered 
into or executed by the Fund. Under the Declaration of Trust, indemnification 
shall be made 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 is 
remote. 

CODE OF ETHICS. Directors, officers and employees of InterCapital, Dean 
Witter Services Company Inc. and the Distributor are subject to a strict Code 
of Ethics adopted by those companies. The Code of Ethics is intended to 
ensure that the interests of shareholders and other clients are placed ahead 
of any personal interest, that no undue personal benefit is obtained from a 
person's employment activities and that actual and potential conflicts of 
interest are avoided. To achieve these goals and comply with regulatory 
requirements, the Code of Ethics requires, among other things, that personal 
securities transactions by employees of the companies be subject to an 
advance clearance process to monitor that no Dean Witter Fund is engaged at 
the same time in a purchase or sale of the same security. The Code of Ethics 
bans the purchase of securities in an initial public offering, and also 
prohibits engaging in futures and options transactions and profiting on 
short-term trading (that is, a purchase within sixty days of a sale or a sale 
within sixty days of a purchase) of a security. In addition, investment 
personnel may not purchase or sell a security for their personal account 
within thirty days before or after any transaction in any Dean Witter Fund 
managed by them. Any violations of the Code of Ethics are subject to 
sanctions, including reprimand, demotion or suspension or termination of 
employment. The Code of Ethics comports with regulatory requirements and the 
recommendations in the 1994 report by the Investment Company Institute 
Advisory Group on Personal Investing. 

MASTER/FEEDER CONVERSION. The Fund reserves the right to seek to achieve its 
investment objective by investing all of its investable assets in a 
diversified, open-end management investment company having the same 
investment objective and policies and substantially the same investment 
restrictions as those applicable to the Fund. 

SHAREHOLDER INQUIRIES.  All inquiries regarding the Fund should be directed 
to the Fund at the telephone numbers or address set forth on the front cover 
of this Prospectus.
