Risk                  The prices of interest-bearing securities are inversely
Considerations        affected by changes in interest rates and, therefore, are
                      subject to the risk of market price fluctuations. The
                      values of fixed-income securities also may be affected by
                      changes in the credit rating or financial condition of
                      the issuing entities. Certain of the tax-exempt
                      securities in which the Fund may invest without limit may
                      subject certain investors to the federal, and any
                      applicable state, alternative minimum tax. (see pages 
                      7-8).

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

   Dean Witter Limited Term Municipal Trust (the "Fund") is a no-load, 
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 February 25, 1993. 

   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 
Inc., 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, 
including this Fund, of approximately $89 billion as of April 30, 1997. The 
Investment Manager also manages portfolios of pensions plans, other 
institutions and individuals which aggregated approximately $3.2 billion at 
such date. 

   The Fund has retained the Investment Manager, pursuant to an Investment 
Management Agreement, 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 the 
annual rate of 0.50% to the Fund's net assets determined as of the close of 
each business day. For the fiscal year ended March 31, 1997, the Fund accrued 
total compensation to the Investment Manager amounting to 0.50% of the Fund's 
average daily net assets and the Fund's total expenses amounted to 0.88% of 
the Fund's average daily net assets. 

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

   The investment objective of the Fund is to provide a high level of current 
income that is exempt from federal income tax, consistent with the 
preservation of capital and prescribed standards of quality and maturity. The 
Fund will seek to achieve its investment objective by investing predominately 
in intermediate term municipal securities. 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. 

   The Fund will invest at least 75% of its net assets in (a) Municipal Bonds 
which are rated at the time of purchase within the three highest grades by 
Moody's Investors Service, Inc. ("Moody's") or Standard & Poor's Corporation 
("S&P"); (b) Municipal Notes which at the time of purchase are rated in the 
two highest grades by Moody's or S&P, or, if not rated, have outstanding one 
or more issues of Municipal Bonds rated as set forth in clause (a) of this 
paragraph; and (c) Municipal Commercial Paper which at the time of purchase 
are rated P-1 by Moody's or A-1 by S&P. The Fund may also invest up to 25% of 
its net assets in municipal securities rated Baa by Moody's or BBB by S&P, or 
if not rated, are determined by the Investment Manager to be the equivalent 
of Baa/BBB or better. A description of municipal security ratings is 
contained in the Appendix to the Statement of Additional Information. 

   The municipal securities in the Fund's portfolio will have an anticipated 
average dollar-weighted maturity range of 7 to 10 years, with a maximum 
average dollar-weighted maturity of 12 years. However, at least 80% of the 
net assets of the Fund will be subject to an average dollar-weighted maturity 
constraint of 15 years. When computing the average dollar-weighted maturity, 
the Fund intends to treat investments which permit the holder to demand 
payment of principal at any time or at specified intervals prior to the 
stated final maturity as having a maturity equal to the next demand date. The 
final maturity of these demand obligations will be no more than 25 years, 
until such time as the Staff of the Securities and Exchange Commission has 
determined the appropriateness of using maturity shortening techniques for 
obligations with longer final maturities. 

   The foregoing percentage and rating limitations apply at the time of 
acquisition of a security based on the last previous determination of the net 
asset value of the Fund. Any subsequent change in any rating by a rating 
service or change in percentages resulting from market fluctuations or other 
changes in total assets of the Fund will not require elimination of any 
security from the Fund's portfolio. Therefore, the Fund may hold securities 
which have been downgraded from ratings of Baa or BBB or lower by Moody's or 
S&P. However such investments may not exceed 5% of the net assets of the 
Fund. Any investments which exceed this limitation will be eliminated from 
the portfolio within a reasonable period of time (such time as the Investment 
Manager determines that it is practicable to sell the investment without 
undue market or tax 

                                                                              5

consequences to the Fund). Municipal obligations rated below investment grade 
by Moody's or S&P are considered to be speculative investments, some of which 
may not be currently paying any interest and may have extremely poor 
prospects of ever attaining any real investment standing. 

   The two principal classifications of municipal obligations and commercial 
paper are "general obligation" and "revenue" obligations or commercial paper. 
General obligation bonds, notes or commercial paper are secured by the 
issuer's pledge of its faith, credit and taxing power for the payment of 
principal and interest. Issuers of general obligation bonds, notes or 
commercial paper include a state, its counties, cities, towns and other 
governmental units. Revenue bonds, notes or commercial paper are payable from 
the revenues derived from a particular facility or class of facilities or, in 
some cases, from specific revenue sources. Revenue bonds, notes or commercial 
paper are issued for a wide variety of purposes, including the financing of 
electric, gas, water and sewer systems and other public utilities; industrial 
development and pollution control facilities; single and multi-family housing 
units; public buildings and facilities; air and marine ports, transportation 
facilities such as toll roads, bridges and tunnels; and health and 
educational facilities such as hospitals and dormitories. They rely primarily 
on user fees to pay debt service, although the principal revenue source is 
often supplemented by additional security features which are intended to 
enhance the creditworthiness of the issuer's obligations. In some cases, 
particularly revenue bonds issued to finance housing and public buildings, a 
direct or implied "moral obligation" of a governmental unit may be pledged to 
the payment of debt service. In other cases, a special tax or other charge 
may augment user fees. 

WHEN-ISSUED AND DELAYED DELIVERY SECURITIES AND FORWARD COMMITMENTS. From 
time to time, in the ordinary course of business, the Fund may purchase 
securities on a when-issued or delayed delivery basis or may purchase or sell 
securities on a forward commitment basis. 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. 
There is no overall limit on the percentage of the Fund's assets which may be 
committed to the purchase of securities on a when-issued, delayed delivery or 
forward commitment basis. An increase in the percentage of the Fund's assets 
committed to the purchase of securities on a when-issued, delayed delivery or 
forward commitment basis may increase the volatility of the Fund's net asset 
value. 

WHEN, AS AND IF ISSUED SECURITIES. The Fund may purchase securities on a 
"when, as and if issued" basis under which the issuance of the security 
depends upon the occurrence of a subsequent event, such as approval of a 
merger, corporate reorganization, leveraged buyout or debt restructuring. If 
the anticipated event does not occur and the securities are not issued, the 
Fund will have lost an investment opportunity. There is no overall limit on 
the percentage of the Fund's assets which may be committed to the purchase of 
securities on a "when, as and if issued" basis. An increase in the percentage 
of the Fund's assets committed to the purchase of securities on a "when, as 
and if issued" basis may increase the volatility of its net asset value. 

HEDGING ACTIVITIES 

Subject to applicable state law, the Fund may enter into financial futures 
contracts, options on such futures and municipal bond index futures contracts 
for hedging purposes. 

FINANCIAL FUTURES CONTRACTS AND OPTIONS ON FUTURES. The Fund may invest in 
financial futures contracts and related options thereon. The Fund may sell a 
financial futures contract or purchase a put option on such futures contract, 
if the Investment Manager anticipates interest rates to rise, as a hedge 
against a decrease in the value of the Funds' portfolio securities. If the 
Investment Manager anticipates that interest rates will decline, the Fund may 
purchase a financial futures contract or a call option thereon to protect 
against an increase in the price of the securities that the Fund intends to 
purchase. These futures contracts and related options thereon will be used 
only as a hedge against anticipated interest rate changes. A futures contract 
sale creates an obligation by the Fund, as seller, to deliver the specific 
type of instrument called for in the contract at a specified future time for 
a specified price. A futures contract purchase would create an obligation by 
the Fund, as purchaser, to take delivery of the specific type of financial 
instrument at a specified future time at a specified price. The specific 
securities delivered or taken, respectively, at settlement date, would not be 
determined until or near that date. The determination would be in accordance 
with the rules of the exchange on which the futures contract sale or purchase 
was effected. 

   Although the terms of financial futures contracts specify actual delivery 
or receipt of securities, in most instances the contracts are closed out 
before the settlement date without the making or taking of delivery of the 
securities. Closing out of a futures contract is effected by entering into an 
offsetting purchase or sale transaction. 
<PAGE>
   Unlike a financial futures contract, which requires the parties to buy and 
sell a security on a set date, an option on such a futures contract entitles 
its holder to decide on or before a future date whether to enter into such a 
contract (a long position in the case of a call option and a short position 
in the case of a put option). If the holder decides not to enter into the 
contract, the premium paid for the option on the contract is lost. Since the 
value of the option is fixed at the point of sale, there are no daily 
payments of cash to reflect the change in the value of the underlying 
contract as there is by a purchaser or seller of a futures contract. The 
value of the option does change and is reflected in the net asset value of 
the Fund. 

MUNICIPAL BOND INDEX FUTURES. The Fund may utilize municipal bond index 
futures contracts for hedging purposes. The strategies in employing such 
contracts will 

6
<PAGE>

be similar to that discussed above with respect to financial futures and 
options thereon. A municipal bond index is a method of reflecting in a single 
number the market value of many different municipal bonds and is designed to 
be representative of the municipal bond market generally. The index 
fluctuates in response to changes in the market values of the bonds included 
within the index. Unlike futures contracts on particular financial 
instruments, transactions in futures on a municipal bond index will be 
settled in cash, if held until the close of trading in the contract. However, 
like any other futures contract, a position in the contract may be closed out 
by a purchase or sale of an offsetting contract for the same delivery month 
prior to expiration of the contract. 

   The Fund may not enter into futures contracts or related options thereon 
if, immediately thereafter, the amount committed to margin plus the amount 
paid for option premiums exceeds 5% of the value of the Fund's total assets. 
The Fund may not purchase or sell futures contracts or related options, if, 
immediately thereafter, more than one-third of the net assets of the Fund 
would be hedged. 

OPTIONS. The Fund may purchase or sell (write) options on debt securities as 
a means of achieving additional return or hedging the value of the Fund's 
portfolio. The Fund would only buy options listed on national securities 
exchanges. The Fund will not purchase options on behalf of the Fund if, as a 
result, the aggregate cost of all outstanding options exceeds 10% of the 
Fund's total assets. 

LENDING OF PORTFOLIO SECURITIES. The Fund will not lend portfolio securities 
if such loans are not permitted by the laws or regulations of any state in 
which its shares are qualified for sale and will not lend more than 25% of 
the value of the total assets of the Fund. 

RISK CONSIDERATIONS 

MUNICIPAL SECURITIES AND RATINGS. 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 and the ability of the issuers of the Fund's portfolio 
securities to pay interest and principal on such obligations on a timely 
basis. 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. 

   Under normal conditions, at least 80% of the total assets of the Fund will 
be invested in securities, the interest on which is exempt from federal 
income taxes. However, the Fund may invest more than 20% of its total assets 
in taxable money market instruments in order to maintain a temporary 
"defensive" position, when, in the opinion of the Investment Manager, 
prevailing market or financial conditions (including unavailability of 
securities of requisite quality) so warrant. Certain of the tax-exempt 
securities in which the Fund may invest without limit may subject certain 
investors to the federal alternative minimum tax or any applicable state 
alternative minimum tax and, therefore, a substantial portion of the income 
produced by the Fund may be taxable to such investors under any federal or 
any applicable state alternative minimum tax. The Fund, therefore, may not be 
a suitable investment for investors who are subject to the alternative 
minimum tax. The suitability of the Fund for these investors will depend upon 
a comparison of the after-tax yield likely to be provided from the Fund to 
comparable tax-exempt investments not subject to such tax and also to 
comparable fully taxable investments in light of each investor's tax 
position. See "Dividends, Distributions and Taxes". 

   Investments in municipal bonds rated either Baa by Moody's or BBB by S&P 
(investment grade bonds--the lowest rated permissible investments by the 
Fund) have speculative characteristics and, therefore, changes in economic 
conditions or other circumstances are more likely to weaken their capacity to 
make principal and interest payments than would be the case with investments 
in securities with higher credit ratings. 

   The ratings assigned by Moody's and S&P represent their opinions as to the 
quality of the securities which they undertake to rate (see the Appendix to 
the Statement of Additional Information). It should be emphasized, however, 
that the ratings are general and not absolute standards of quality. 
<PAGE>
LEASE OBLIGATIONS. Included within the revenue bonds category, as noted 
above, are participations in lease obligations or installment purchase 
contracts (hereinafter collectively called "lease obligations") of 
municipalities. State and local governments, agencies or authorities issue 
lease obligations to acquire equipment and facilities. Lease obligations may 
have risks not normally associated with general obligation or other revenue 
bonds. Leases, and installment purchase or conditional sale contracts (which 
may provide for title to the leased asset to pass eventually to the issuer), 
have developed as a means for governmental issuers to acquire property and 
equipment without the necessity of complying with the constitutional and 
statutory requirements generally applicable for the issuance of debt. Certain 
lease obligations contain "non-appropriation" clauses that provide that the 
governmental issuer has no obligation to make future payments under the lease 
or contract unless money is appropriated for such purpose by the appropriate 
legislative body on an annual or other periodic basis. Consequently, 
continued lease payments on those lease obligations containing 
"non-appropriation" clauses are dependent on future legislative actions. If 
such legislative actions do not occur, the holders of the lease obligation 
may experience difficulty in exercising their rights, including disposition 
of the property. 

   In addition, lease obligations represent a relatively new type of 
financing that has not yet developed the depth of marketability associated 
with more conventional municipal obligations, and, as a result, certain of 
such lease obligations may be considered illiquid securities. To determine 
whether 

                                                                              7
<PAGE>

or not the Fund will consider such securities to be illiquid (the Fund may 
not invest more than fifteen percent of its net assets in illiquid 
securities), the Trustees of the Fund have established guidelines to be 
utilized by the Fund in determining the liquidity of a lease obligation. The 
factors to be considered in making the determination include: 1) the 
frequency of trades and quoted prices for the obligation; 2) the number of 
dealers willing to purchase or sell the security and the number of other 
potential purchasers; 3) the willingness of dealers to undertake to make a 
market in the security; and 4) the nature of the marketplace trades, 
including the time needed to dispose of the security, the method of 
soliciting offers, and the mechanics of the transfer. 

FUTURES CONTRACTS AND OPTIONS ON FUTURES. A risk in employing futures 
contracts to protect against the price volatility of portfolio securities is 
that the prices of securities subject to such futures contracts may correlate 
imperfectly with the behavior of the cash prices of the Fund's portfolio 
securities. The risk of imperfect correlation will be increased by the fact 
that the financial futures contracts in which the Fund may invest are on 
taxable securities rather than tax-exempt securities, and there is no 
guarantee that the prices of taxable securities will move in a similar manner 
to the prices of tax-exempt securities. The correlation may be distorted by 
the fact that the futures market is dominated by short-term traders seeking 
to profit from the difference between a contract or security price objective 
and their cost of borrowed funds. Such distortions are generally minor and 
would diminish as the contract approached maturity. 

   Another risk is that the Investment Manager could be incorrect in its 
expectations as to the direction or extent of various interest rate movements 
or the time span within which the movements take place. For example, if the 
Fund sold financial futures contracts for the sale of securities in 
anticipation of an increase in interest rates, and then interest rates went 
down instead, causing bond prices to rise, the Fund would lose money on the 
sale. 

   In addition to the risks that apply to all options transactions (see the 
Statement of Additional Information for a description of the characteristics 
of, and the risks of investing in, options on debt securities), there are 
several special risks relating to options on futures. In particular, the 
ability to establish and close out positions on such options will be subject 
to the development and maintenance of a liquid secondary market. It is not 
certain that this market will develop or be maintained. 

ZERO COUPON SECURITIES. A portion of the fixed-income securities purchased by 
the Fund may be zero coupon securities. Such securities are purchased at a 
discount from their face amount, giving the purchaser the right to receive 
their full value at maturity. 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 higher yields upon 
reinvestment of interest received on interest-paying securities if prevailing 
interest rates rise. 

   A zero coupon security pays no interest to its holder during its life. 
Therefore, to the extent the Fund invests in zero coupon securities, it will 
not receive current cash available for distribution to shareholders. In 
addition, zero coupon securities are subject to substantially greater price 
fluctuations during periods of changing prevailing interest rates than are 
comparable securities which pay interest on a current basis. 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. 

   For additional risk disclosure, please refer to the "Investment Objective 
and Policies" section of the Prospectus and to the "Investment Practices and 
Policies" section of the Statement of Additional Information. 

PORTFOLIO MANAGEMENT 

The Fund's portfolio is actively managed by its Investment Manager with a 
view to achieving the Fund's investment objective. The Fund is managed within 
InterCapital's Tax-Exempt Group, which manages 40 tax-exempt municipal bond 
funds, with approximately $10.5 billion in assets as of April 30, 1997. Ms. 
Katherine H. Stromberg is the Fund's portfolio manager. Ms. Stromberg has 
been a municipal bond portfolio manager for more than 15 years and has been a 
portfolio manager at InterCapital for over five years. 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"), a broker-dealer affiliate of the Investment 
Manager; the views of the Trustees of the Fund and others regarding economic 
developments and interest rate trends; and the Investment Manager's own 
analysis of factors it deems relevant. 

   Brokerage commissions are not normally charged on the purchase or sale of 
municipal 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 taxable money market instruments with DWR. In addition, the Fund may 
incur brokerage commissions on futures' and options' transactions conducted 
through DWR. It is not anticipated that the portfolio trading engaged in by 
the Fund will result in its portfolio turnover rate exceeding 100%.

INVESTMENT RESTRICTIONS 
- -------------------------------------------------------------------------------

   The investment restrictions listed below are among the restrictions, a 
complete listing of which is contained in the Statement of Additional 
Information, which have been adopted by the Fund as fundamental policies. 
Under the Investment Company Act of 1940, as amended (the "Act"), a 
fundamental policy may not be changed without the vote of a majority of the 
outstanding voting securities of the Fund, as defined in the Act. 

   For purposes of the following restrictions: (a) an "issuer" of a security 
is the entity whose assets and revenues are committed to the payment of 
interest and principal on that particular security, provided that the 
guarantee of a security will be considered a separate security and provided 
further that a guarantee of a security shall not be deemed to be a security 
issued by the guarantor if the value of all securities issued or guaranteed 
by the guarantor and owned by the Fund does not exceed 10% of the value of 
the total assets of the Fund; (b) a "taxable security" is any security the 
interest on which is subject to federal income tax; and (c) all percentage 
limitations apply immediately after a purchase or initial investment, and any 
subsequent change in any applicable percentage resulting from market 
fluctuations does not require elimination of any security from the portfolio. 

The Fund may not: 

   1. With respect to 75% of its total assets, purchase securities of any 
issuer if, immediately thereafter, more than 5% of the value of its total 
assets are in the securities of any one issuer (other than obligations 
issued, or guaranteed by, the United States Government, its agencies or 
instrumentalities). 

   2. With respect to 75% of its total assets, purchase more than 10% of all 
outstanding taxable debt securities of any one issuer (other than debt 
securities issued, or guaranteed as to principal and interest by, the United 
States Government, its agencies or instrumentalities). 

   3. Invest 25% or more of the value of its total assets in securities of 
issuers in any one industry (industrial development and pollution control 
bonds are grouped into industries based upon the business in which the 
issuers of such obligations are engaged). This restriction does not apply to 
obligations issued or guaranteed by the United States Government, its 
agencies or instrumentalities or to domestic bank obligations. 

   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. 

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

   The Fund offers it shares for sale to the public on a continuous basis at 
the offering price without the imposition of a sales charge. The offering 
price will be the net asset value per share next determined following receipt 
of an order (see "Determination of Net Asset Value"). 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 are offered by DWR and other 
broker-dealers which have entered into selected broker-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 $1,000 and subsequent purchases of $100 or 
more may be made by sending a check, payable to Dean Witter Limited Term 
Municipal Trust, directly to Dean Witter Trust Company (the "Transfer Agent") 
at P.O. Box 1040, Jersey City, NJ 07303 or by contacting an account executive 
of DWR or of another Selected Broker-Dealer. The minimum initial purchase in 
the case of investments through EasyInvestSM, an automatic purchase plan (see 
"Shareholder Services"), is $100, provided that the schedule of automatic 
investments will result in investments totalling at least $1,000 within the 
first twelve months. In the case of investments pursuant to Systematic 
Payroll Deduction 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. Certificates 
for shares purchased will not be issued unless a request is made by the 
shareholder in writing to the Transfer Agent. 

   Shares of the Fund are sold through the Distributor or a Selected 
Broker-Dealer on a normal three business day settlement basis; that is, 
payment is due on the third business day (settlement date) after the order is 
placed with the Distributor or Selected Broker-Dealer. Shares of the Fund 
purchased through the Distributor are entitled to dividends beginning on the 
next business day following settlement date. Since DWR or other Selected 
Broker-Dealers forward investors' funds on settlement date, they will benefit 
from the temporary use of the funds if payment is made prior thereto. Shares 
purchased through the Transfer Agent are entitled to dividends beginning on 
the next business day following receipt of an order. As noted above, orders 
placed directly with the Transfer Agent must be accompanied by payment. 
Investors will be entitled to receive capital gains distributions if their 
order is received 

                                                                              9
<PAGE>

by the close of business on the day prior to the record date for such 
distributions. Investors will be entitled to receive income dividends if 
their order is received by the close of business on the day prior to the 
record date for such dividends and distributions. 

   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 non-cash compensation as special sales incentives, 
including trips, educational and/or business seminars and merchandise. The 
Fund and the Distributor reserve the right to reject any purchase orders. 

PLAN OF DISTRIBUTION 

The Fund has entered into a Plan of Distribution pursuant to Rule 12b-1 under 
the Act with the Distributor whereby the Distributor is authorized to utilize 
its own resources or those of its affiliates, including InterCapital, to 
finance certain services and activities in connection with the distribution 
of the Fund's shares. The principal activities and services which may be 
provided by the Distributor, DWR, its affiliates and other Selected 
Broker-Dealers under the Plan include: (1) compensation to, and expenses of, 
account executives and other employees of DWR and other Selected 
Broker-Dealers, 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. 

DETERMINATION OF NET ASSET VALUE 

The net asset value per share of the Fund is determined once daily at 4:00 
p.m., New York time (or, on days when the New York Stock Exchange closes 
prior to 4:00 p.m., at such earlier time), on each day that the New York 
Stock Exchange is open by taking the value of all assets of the Fund, 
subtracting all of its respective liabilities, dividing by the number of 
shares outstanding and adjusting to the nearest cent. The net asset value per 
share of the Fund 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. 

   Certain of the Fund's portfolio securities (other than short-term taxable 
debt securities, futures and options) may be valued by an outside independent 
pricing service approved by the Fund's Trustees. The service may utilize a 
computerized grid matrix of tax-exempt securities and evaluations by its 
staff in determining what it believes is the fair value of the Fund's 
portfolio securities. The Board believes that timely and reliable market 
quotations are generally not readily available to the Fund for purposes of 
valuing tax-exempt securities and that the valuations supplied by the pricing 
service are more likely to approximate the fair value of such securities. A 
more detailed discussion of valuation procedures is in the Fund's Statement 
of Additional Information. 

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 (or, if specified by the shareholder, any other open-end 
investment company for which InterCapital serves as investment manager 
(collectively, with the Fund, the "Dean Witter Funds")), unless the 
shareholder requests that they be paid in cash. Such dividends and 
distributions will be paid, at the net asset value per share, in shares of 
the Fund (or in cash if the shareholder so requests) on the monthly payment 
date, which will be no later than the last business day of the month for 
which the dividend or distribution is payable. Processing of dividend checks 
begins immediately following the monthly payment date. Shareholders who have 
requested to receive dividends in cash will normally receive their monthly 
dividend check during the first ten days of the following month. 

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. 
<PAGE>
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 net asset 
value. 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. 
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 could 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, for state and 
local tax purposes. 

   Shareholders should contact their DWR or other Selected Broker-Dealer 
account executive or the Transfer Agent for further information about any of 
the above services. 

EXCHANGE PRIVILEGE. An "Exchange Privilege," that is, the privilege of 
exchanging shares of certain Dean Witter 

10
<PAGE>

Funds for shares of the Fund, exists whereby shares of various Dean Witter 
Funds which are open-end investment companies sold with either a front-end 
(at time of purchase) sales charge ("FESC funds") or a contingent deferred 
sales charge ("CDSC funds") may be redeemed at their next calculated net 
asset value and the proceeds of the redemption may be used to purchase shares 
of the Fund, shares of Dean Witter Tax-Free Daily Income Trust, Dean Witter 
U.S. Government Money Market Trust, Dean Witter Liquid Asset Fund Inc., Dean 
Witter California Tax-Free Daily Income Trust and Dean Witter New York 
Municipal Money Market Trust (which five funds are hereinafter called "money 
market funds") and shares of Dean Witter Short-Term U.S. Treasury Trust, Dean 
Witter Short-Term Bond Fund, Dean Witter Intermediate Term U.S. Treasury 
Trust, Dean Witter Balanced Income Fund and Dean Witter Balanced Growth Fund 
(collectively, the Fund, the money market funds, Dean Witter Short-Term U.S. 
Treasury Trust, Dean Witter Short-Term Bond Fund, Dean Witter Intermediate 
Term U.S. Treasury Trust, Dean Witter Balanced Income Fund and Dean Witter 
Balanced Growth Fund are referred to herein as the "Exchange Funds"). An 
exchange from an FESC fund or a CDSC fund to an Exchange 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 from an 
FESC fund or a CDSC fund, shares of the FESC fund or the CDSC 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. Subsequently, shares of the Exchange Funds received in an 
exchange for shares of an FESC fund (regardless of the type of fund 
originally purchased) may be redeemed and exchanged for shares of the other 
Exchange Funds, FESC funds or CDSC funds (however, shares of CDSC funds, 
including shares acquired in exchange for (i) shares of FESC funds or (ii) 
shares of the Exchange Funds which were acquired in exchange for shares of 
FESC funds, may not be exchanged for shares of FESC funds). Additionally, 
shares of the Exchange Funds received in an exchange for shares of a CDSC 
fund (regardless of the type of fund originally purchased) may be redeemed 
and exchanged for shares of the other Exchange Funds or CDSC funds. 
Ultimately, any applicable contingent deferred sales charge ("CDSC") will 
have to be paid upon redemption of shares originally purchased from a CDSC 
fund. (If shares of the Exchange Funds received in exchange for shares 
originally purchased from a CDSC fund are exchanged for shares of another 
CDSC fund having a different CDSC schedule than that of the CDSC fund from 
which the Exchange Funds 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 remain in the Exchange Funds (calculated from the 
last day of the month in which the Exchange Funds shares were acquired), the 
holding period (for the purpose of determining the rate of CDSC) is frozen. 
If those shares are subsequently reexchanged for shares of a CDSC fund, the 
holding period previously frozen when the first exchange was made resumes on 
the last day of the month in which shares of CDSC fund are reacquired. Thus, 
the CDSC is based upon the period of time the shareholder was invested in a 
CDSC fund. Exchanges involving FESC funds or CDSC funds may be made after the 
shares of the FESC fund or CDSC 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. 

   Purchases and exchanges should be made for investment purposes only. A 
pattern of frequent exchanges may be deemed by the Investment Manager to be 
abusive and contrary to the best interests of the Fund's other shareholders 
and, at the Investment Manager'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. Also, 
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. Shareholders maintaining margin accounts with DWR or another 
Selected Broker-Dealer are referred to their account executive regarding 
restrictions or exchanging of shares of the Fund pledged in the 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 and 
any other conditions imposed by each fund. An exchange will be treated for 
federal income tax purposes the same as a repurchase or redemption of shares 
on which the shareholder has realized 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 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 (for which the Exchange Privilege is available) pursuant to 
this Exchange Privilege by contacting their DWR or an other Selected 
Broker-Dealer account executive (no Exchange Privilege Authorization Form is 
required). Other shareholders (and those 

                                                                             11
<PAGE>

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 in writing or 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 may 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 may 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 other 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 
- -------------------------------------------------------------------------------

   REDEMPTION. Shares of the Fund can be redeemed for cash at any time at its 
respective current net asset value per share (without any redemption or other 
charge). If shares are held in a shareholder's account without a share 
certificate, a written request for redemption is required. If certificates 
are held by the shareholder, the shares may be redeemed by surrendering the 
certificates with a written request for redemption along with any additional 
documentation required by the Transfer Agent, to the Fund's Transfer Agent at 
P.O. Box 983, Jersey City, NJ 07303. 

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 by 
DWR and other Selected Broker-Dealers. 

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 another Selected Broker-Dealer are referred to their 
account executive regarding restrictions on redemption of shares of the Fund 
pledged in the margin account. 

INVOLUNTARY REDEMPTION. The Fund reserves the right to redeem, on 60 days' 
notice and at net asset value, the shares (other than shares held in an 
Individual Retirement Account or Custodial Account under Section 403(b)(7) of 
the Internal Revenue Code) of any shareholder whose shares have a value of 
less than $100 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 EasyInvestSM, if after twelve months the shareholder has invested 
less than $1,000 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 the 
shareholder sixty 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 before the redemption is processed. 

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

   Dividends and Distributions. The Fund declares dividends on each day the 
New York Stock Exchange is open for business. Such dividends are payable 
monthly. The Fund intends to distribute substantially all of its daily net 
investment income on an annual basis. Dividends from net short-term capital 
gains, if any, will be paid at least once each year. The Fund may, however, 
determine either to distribute or to retain all or part of any net long-term 
capital gains in any year for reinvestment. Any dividends or distributions 
declared in the last quarter of any calendar year which are paid in the 
following calendar year prior to February 1 will be deemed received by the 
shareholder in the prior calendar year. Shareholders may instruct the 
Transfer Agent (in writing) to have their dividends paid out 

12
<PAGE>

monthly in cash. Processing of dividend checks begins immediately following 
the monthly payment date. Shareholders who have requested to receive 
dividends in cash will normally be sent their monthly dividend check during 
the first ten days of the following month. 

   Taxes. Because the Fund intends to distribute substantially all of its net 
investment income and net capital gains, if any, to shareholders, and intends 
to otherwise comply with all the provisions of Subchapter M of the Internal 
Revenue Code of 1986, as amended (the "Code"), to qualify as a regulated 
investment company ("RIC"), it is not expected that the Fund will be required 
to pay any federal income tax. 

   The Fund intends to qualify to pay "exempt-in terest dividends" to its 
shareholders by maintaining, as of the close of each quarter of its taxable 
year, at least 50% of the value of its total assets in tax-exempt securities. 
If the fund qualifies as a RIC and satisfies such requirement, dividends from 
net investment income to shareholders, whether taken in cash or reinvested in 
additional Fund shares, will be excludable from gross income for federal 
income tax purposes to the extent net interest income is represented by 
interest on tax-exempt securities. Exempt-interest dividends are included, 
however, in determining what portion, if any, of a person's Social Security 
benefits are subject to federal income tax. 

   The Code subjects interest received on certain otherwise tax-exempt 
securities to an alternative minimum tax. This alternative minimum tax 
applies to interest received on "private activity bonds" (in general, bonds 
that benefit non-governmental entities) issued after August 7, 1986 which, 
although tax-exempt, are used for purposes other than those generally 
performed by governmental units (e.g., bonds used for commercial or housing 
purposes). Income received on such bonds is classified as a "tax preference 
item," under the alternative minimum tax, for both individual and corporate 
investors. There is no percentage limitation with respect to the Fund's 
investments in such "private activity bonds," with the result that a portion 
of the exempt-interest dividends paid by the Fund may be an item of tax 
preference to shareholders subject to the alternative minimum tax. In 
addition, certain corporations which are subject to the alternative minimum 
tax may have to include a portion of exempt-interest dividends in calculating 
their alternative minimum taxable income in situations where the "adjusted 
current earnings" of the corporation exceeds its alternative minimum taxable 
income. 

   The Fund will mail to shareholders a statement indicating the percentage 
of the dividend distributions for each taxable year which constitutes 
exempt-interest dividends and the percentage, if any, that is taxable, and 
the percentage, if any, of the exempt-interest dividends which constitutes an 
item of tax preference. 

   Shareholders will normally be subject to federal personal income tax on 
market discount on certain taxable and tax-exempt fixed-income securities, 
dividends paid from interest income derived from taxable securities and on 
distributions of net capital gains. For federal income tax purposes, 
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 cash. To avoid being subject to a 31% backup withholding 
tax on taxable dividends and capital gains distributions and the proceeds of 
redemptions and repurchases, shareholders' taxpayer identification numbers 
must be furnished and certified as to accuracy. Interest on indebtedness 
incurred by shareholders or related parties to purchase or carry shares of an 
investment company paying exempt-interest dividends, such as the Fund, will 
not be deductible by the investor for federal income tax purposes. 

   Under the Revenue Reconciliation Act of 1993, all or a portion of the 
Fund's gain from the sale or redemption of tax-exempt obligations purchased 
at a market discount after April 30, 1993 will be treated as ordinary income 
rather than capital gain. This rule may increase the amount of ordinary 
income dividends received by shareholders. 

   The foregoing relates to federal income taxation as in effect as of the 
date of this Prospectus. Distributions from investment income and capital 
gains, including exempt-interest dividends, may be subject to state franchise 
taxes if received by a corporation doing business in various states, and to 
state and local taxes. Shareholders should consult their tax advisers as to 
the applicability of the above to their own tax situation. 

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 Fund's 
net investment income over a 30-day period by an average value (using the 
average number of shares entitled to receive dividends and the maximum 
offering price 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 Fund's yield. The 
Fund may also quote 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 of $1,000 over periods of one, five and ten 
years, as well as the life of the Fund if less than any of the foregoing. 

                                                                              13
<PAGE>

Average annual total return reflects all income earned by the Fund, any 
appreciation or depreciation of the Fund's assets and all expenses incurred 
by the Fund for the stated periods. It also assumes reinvestment of all 
dividends and distributions paid by the Fund. 

   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 (such as Lipper Analytical Services Inc.) and 
indices compiled by independent organizations (such as the Lehman Brothers 
Municipal Bond Index and Sub-indices). 

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. 

   The Fund is not required to hold Annual Meetings of Shareholders and, in 
ordinary circumstances, the Fund does not intend to hold such meetings. 

   Under Massachusetts law, shareholders of a business trust may, under 
certain circumstances, be held personally liable as partners for 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 
Fund documents include such disclaimer and provides for indemnification and 
reimbursement of expenses 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, in the opinion of 
Massachusetts counsel to the Fund, the risk to Fund shareholders of personal 
liability 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 60 days of a sale or a sale 
within 60 days of a purchase) of a security. In addition, investment 
personnel may not purchase or sell a security for their personal account 
within 30 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 addresses set forth on the front cover 
of this Prospectus.
