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

   Dean Witter Tax-Free Daily Income Trust (the "Fund") is an open-end, 
diversified management investment company incorporated in Maryland on March 
24, 1980. The Fund was reorganized as a trust of the type commonly known as a 
"Massachusetts business trust" on April 30, 1987. Prior to February 19, 1993, 
the Fund's name was Dean Witter/Sears Tax-Free Daily Income Trust. 

   
   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 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 103 investment companies, 29 of which 
are listed on the New York Stock Exchange, with combined total 
    

                                4           
<PAGE>
   
assets including this Fund of approximately $101 billion as of January 31, 
1998. The Investment Manager also manages portfolios of pension plans, other 
institutions and individuals which aggregated approximately $4 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 at the annual 
rate of 0.50% of the daily net assets of the Fund up to $500 million, scaled 
down at various asset levels to 0.25% on assets over $3 billion. For the 
fiscal year ended December 31, 1997, the Fund accrued total compensation to 
the Investment Manager amounting to 0.49% of the Fund's average daily net 
assets and the Fund's total expenses amounted to 0.72% of the Fund's average 
daily net assets. 
    

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

   The investment objective of the Fund is to provide as high a level of 
daily income exempt from federal income tax as is consistent with stability 
of principal and liquidity. It is a fundamental policy of the Fund that at 
least 80% of its total assets will be invested in securities the interest on 
which is exempt from federal income tax. This policy and the Fund's 
investment objective may not be changed without a vote of a majority of the 
Fund's outstanding voting securities, as defined in the Investment Company 
Act of 1940, as amended (the "Act"). There is no assurance that the objective 
will be achieved. 

   The Fund seeks to achieve its investment objective by investing primarily 
in high quality tax-exempt securities with short-term maturities as follows: 
(i) Municipal Bonds, Municipal Notes and Municipal Commercial Paper with 
remaining maturities of thirteen months or less which are rated at the time 
of purchase in one of the two highest rating categories for debt obligations 
by at least two nationally recognized statistical rating organizations 
("NRSROs") primarily Moody's Investors Service, Inc. ("Moody's") or Standard 
and Poor's Corporation ("S&P"), or one NRSRO if the obligation is rated by 
only one NRSRO. Unrated obligations may be purchased if they are determined 
to be of comparable quality by the Fund's Board of Trustees. 

   Up to 20% of the Fund's total assets may be invested in tax-exempt 
securities subject to the alternative minimum tax ("AMT") (tax-exempt 
securities which are subject to the AMT will not be included in the 80% total 
referred to above). 

   Inclusive of the 20% total referred to above, up to 20% of the Fund's 
total assets may be invested in taxable securities. In addition, the Fund may 
temporarily invest more than 20% of its total assets in taxable securities, 
or in tax-exempt securities subject to the federal AMT for individual 
shareholders, to maintain a "defensive" posture when, in the opinion of the 
Investment Manager, it is advisable to do so because of market conditions. 
The types of taxable securities in which the Fund may temporarily invest are 
limited to the following short-term fixed-income securities (maturing in one 
year or less from the time of purchase): (i) obligations of the United States 
Government or its agencies, instrumentalities or authorities; (ii) commercial 
paper rated P-1 by Moody's or A-1 by S&P; (iii) certificates of deposit of 
domestic banks with assets of $1 billion or more; and (iv) repurchase 
agreements with respect to any of the foregoing portfolio securities. 

                                5           
<PAGE>
   Municipal Bonds and Municipal Notes are debt obligations of a state, its 
cities, municipalities and municipal agencies which generally have 
maturities, at the time of their issuance, of either one year or more (Bonds) 
or from six months to three years (Notes). Municipal Commercial Paper refers 
to short-term obligations of municipalities which may be issued at a discount 
and are sometimes referred to as Short-Term Discount Notes. Any Municipal 
Bond or Municipal Note which depends directly or indirectly on the credit of 
the Federal Government, its agencies or instrumentalities shall be considered 
to have a Moody's rating of Aaa. 

   The foregoing percentage and rating limitations apply at the time of 
acquisition of a security based on the last previous determination of the 
Fund's net asset value. Any subsequent change in any rating by a rating 
service or change in percentages resulting from market fluctuations will not 
require elimination of any security from the Fund's portfolio. However, in 
accordance with procedures adopted by the Fund's Trustees pursuant to federal 
securities regulations governing money market funds, if the Investment 
Manager becomes aware that a portfolio security has received a new rating 
from an NRSRO that is below the second highest rating, then unless the 
security is disposed of within five days, the Investment Manager will perform 
a creditworthiness analysis of any such downgraded securities, which analysis 
will be reported to the Trustees who will, in turn, determine whether the 
securities continue to present minimal credit risks to the Fund. 

   The ratings assigned by NRSROs 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. 

   The two principal classifications of Municipal Bonds, Notes and Commercial 
Paper are "general obligation" and "revenue" bonds, notes 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. 

   Included within the revenue bonds category are participations in lease 
obligations or installment purchase contracts (hereinafter collectively 
called "lease obligations") of municipalities. State and local governments 
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 

                                6           
<PAGE>
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. 

   Certain lease obligations have 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 or not the Fund will consider such 
securities to be illiquid (the Fund may not invest more than ten 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. 

   The Fund does not generally intend to invest more than 25% of its total 
assets in securities of governmental units located in any one state, 
territory or possession of the United States. The Fund may invest more than 
25% of its total assets in industrial development and pollution control bonds 
(two kinds of tax-exempt Municipal Bonds) whether or not the users of 
facilities financed by such bonds are in the same industry. In cases where 
such users are in the same industry, there may be additional risk to the Fund 
in the event of an economic downturn in such industry, which may result 
generally in a lowered need for such facilities and a lowered ability of such 
users to pay for the use of such facilities. 

   The high quality, short-term fixed-income securities in which the Fund 
principally invests are guaranteed by state and local governments and are 
subject to minimal risk of loss of income and principal. 

PORTFOLIO MANAGEMENT 

   Although the Fund will generally acquire securities for investment with 
the intent of holding them to maturity and will not seek profits through 
short-term trading, the Fund may dispose of any security prior to its 
maturity to meet redemption requests. Securities may also be sold when the 
Fund's Investment Manager believes such dispositon to be advisable on the 
basis of a revised evaluation of the issuer or based upon relevant market 
considerations. There may be occasions when, as a result of maturities of 
portfolio securities or sales of Fund shares, or in order to meet anticipated 
redemption requests, the Fund may hold cash which is not earning income. 

   The Fund anticipates that the average weighted maturity of the portfolio 
will be 90 days or less. The relatively short-term nature of the Fund's 
portfolio is expected to result in a lower yield than portfolios comprised of 
longer-term tax-exempt securities. 

   Variable Rate and Floating Rate Obligations. The interest rates payable on 
certain Municipal Bonds and Municipal Notes are not fixed and may fluctuate 
based upon changes in market rates. Municipal obligations of this type are 
called "variable rate" or "floating rate" obligations. The interest rate 
payable on a variable rate obligation is adjusted either at predesignated 
periodic intervals or whenever there is a change in the market rate of 
interest on which the interest rate payable is based. 

   When-Issued and Delayed Delivery Securities. The Fund may purchase 
tax-exempt securities on a when-issued or delayed delivery basis; i.e., 
delivery and payment can take place a month or more after the date of the 
transaction. These securities are subject to market fluctuation and no 
interest accrues to the purchaser prior to settlement. At the time the Fund 
makes the commitment to purchase such 

                                7           
<PAGE>
securities, it will record the transaction and thereafter reflect the value, 
each day, of such securities in determining its net asset value. 

   
   Brokerage Allocation. Brokerage commissions are not normally charged on 
purchases and sales of short-term municipal obligations, but such 
transactions may involve transaction 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 Dean Witter Reynolds Inc. ("DWR"), a broker-dealer 
affiliate of InterCapital. In addition, the Fund may incur brokerage 
commissions on transactions conducted through DWR, Morgan Stanley & Co. 
Incorporated and other broker-dealer affiliates of InterCapital. 
    

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

   The investment restrictions listed below are among the restrictions which 
have been adopted by the Fund as fundamental policies. Under 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. Invest more than 5% of the value of its total assets in the securities 
of any one issuer (other than obligations issued, or guaranteed by, the 
United States Government, its agencies or instrumentalities). 

   2. Purchase 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 more than 25% of the value of its total assets in taxable 
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 cash equivalents. 

   4. Invest more than 5% of the value of its total assets in taxable 
securities of issuers having a record, together with predecessors, of less 
than three years of continuous operation. This restriction shall not apply to 
any obligation of the Unites States Government, its agencies or 
instrumentalities. 

   
   Notwithstanding any other investment policy or restriction, the Trust 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 Trust.

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

   
   The Fund offers its own shares for sale to the public on a continuous 
basis, without a sales charge. 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 other dealers who have entered into 
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 offering price will be the net asset value next 
determined (see "Determination of Net Asset Value" below) after receipt of a 
purchase order and acceptance by the Fund's transfer agent, Dean Witter Trust 
FSB (the "Transfer Agent" or "DWT") 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. Shares commence earning income on the day following the date of 
purchase. Share certificates will not be issued unless requested in writing 
by the shareholder. 

   To initiate purchase by mail or wire, a completed Investment Application 
(contained in the Prospectus) must be sent to Dean Witter Trust FSB at P.O. 
Box 1040, Jersey City, N.J. 07303. Checks should be made payable to the Dean 
Witter Tax-Free Daily Income Trust and sent to Dean Witter Trust FSB at the 
same address. Purchases by wire must be preceded by a call to the Transfer 
Agent advising it of the purchase (see Investment Application or the front 
cover of this Prospectus for instructions and telephone numbers) and must be 
wired to The Bank of New York, for credit to the Account of Dean Witter Trust 
FSB, Harborside Financial Center, Plaza Two, Jersey City, New Jersey, Account 
No. 8900188413. Wire purchase instructions must include the name of the Fund 
and the Shareholder's account number. Purchases made by check are normally 
effective within two business days for checks drawn on Federal Reserve System 
member banks, and longer for most other checks. Wire purchases received by 
the Transfer Agent prior to 12:00 noon New York time are normally effective 
that day and wire purchases received after 12:00 noon New York time are 
normally effective the next business day. Initial investments must be at 
least $5,000, although the Fund, at its discretion, may accept initial 
investments of smaller amounts, not less than $1,000. Subsequent investments 
must be $100 or more and may be made through the Transfer Agent. 

   In the case of investments pursuant to (i) Systematic Payroll Deduction 
Plans (including Individual Retirement Plans), (ii) the InterCapital mutual 
fund asset allocation program and (iii) fee-based programs approved by the 
Distributor, pursuant to which participants pay an asset based fee for 
services in the nature of investment advisory or administrative services, the 
Fund, in its discretion, may accept investments without regard to any minimum 
amounts which would otherwise be required, provided, in the case of 
Systematic Payroll Deduction Plans, that the Distributor has reason to 
believe that additional investments will increase the investment in all 
accounts under such Plans to at least $5,000. The Fund and the Distributor 
reserve the right to reject any purchase order. 
    

   Sales personnel are compensated for selling shares of the Fund at the time 
of their sale by the Distributor and/or the 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, educational and/or business seminars and merchandise. 

   Orders for the purchase of Fund shares placed by customers through DWR or 
another Selected Broker-Dealer with payment in clearing house funds will be 
transmitted to the Fund with payment in Federal Funds on the business day 
following the day the order is placed by the customer with DWR or another 
Selected Broker-Dealer. Investors desir- 

                                9           
<PAGE>
   
ing same day effectiveness should wire Federal Funds directly to the Transfer 
Agent. An order procedure exists pursuant to which customers can, upon 
request: (a) have the proceeds from the sale of listed securities invested in 
shares of the Fund on the day following the day the customer receives such 
proceeds in his or her DWR or other Selected Broker-Dealer brokerage account; 
and (b) pay for the purchase of certain listed securities by automatic 
liquidation of Fund shares owned by the customer. In addition, there is an 
automatic purchase procedure whereby consenting DWR or other Selected 
Broker-Dealer customers who are shareholders of the Fund will have free cash 
credit balances in their DWR or other Selected Broker-Dealer brokerage 
accounts as of the close of business (4:00 p.m., New York time) on the last 
business day of each week (where such balances do not exceed $5,000) 
automatically invested in shares of the Fund the next following business day. 
Investors with free cash credit balances (i.e., immediately available funds) 
in brokerage accounts at DWR or another Selected Broker-Dealer will not have 
any of such funds invested in the Fund until the business day after the 
customer places an order with DWR or another Selected Broker-Dealer to 
purchase shares of the Fund and will not receive the daily dividend which 
would have been received had such funds been invested in the Fund on the day 
the order was placed with DWR or other Selected Broker-Dealers. Accordingly, 
DWR or other Selected Broker-Dealers may have the use of such free credit 
balances during such period. 
    

PLAN OF DISTRIBUTION 

   
   The Fund has entered into a Plan of Distribution with the Distributor 
pursuant to Rule 12b-1 under the Act whereby the expenses of certain 
activities in connection with the distribution of Fund shares are reimbursed. 
The principal activities and services which may be provided by the 
Distributor, DWR, its affiliates or any other Selected Broker-Dealers under 
the Plan include: (1) compensation to and expenses of, DWR's and other 
Selected Broker-Dealers' account executives and other employees including 
overhead and telephone expenses; (2) sales incentives and bonuses to sales 
representatives and to marketing personnel in connection with promoting sales 
of the Fund's shares; (3) expenses incurred in connection with promoting 
sales of the Fund's shares; (4) preparing and distributing sales literature; 
and (5) providing advertising and promotional activities, including direct 
mail solicitation and television, radio, newspaper, magazine and other media 
advertisements. Reimbursements 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 0.15 of 1% of the Fund's average daily net 
assets. For the fiscal year ended December 31, 1997, the fee accrued was 
equal to payment at an annual rate of 0.10 of 1% of the Fund's average daily 
net assets. 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. 
    

DETERMINATION OF NET ASSET VALUE 

   The net asset value per share of the Fund is determined as of the close of 
trading (presently 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) by taking the value of all assets 
of the Fund, subtracting its liabilities and dividing by the number of shares 
outstanding. 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. 

   The Fund utilizes the amortized cost method in valuing its portfolio 
securities, which method involves valuing a security at its cost adjusted by 
a constant amortization to maturity of any discount or premium, regardless of 
the impact of fluctuating interest rates on the market value of the 
instrument. The purpose of this method of calculation is to facilitate the 
maintenance of a constant net asset value per share of $1.00. However, there 
can be no assurance that the $1.00 net asset value will be maintained.

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

   
   Systematic Withdrawal Plan. A systematic withdrawal plan is available for 
shareholders who own or purchase shares of the Fund having a minimum value of 
at least $5,000. The plan provides for monthly or quarterly (March, June, 
September, 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 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 days after the 
date of redemption. A shareholder wishing to make this election should do so 
on the Investment Application. The withdrawal plan may be terminated at any 
time by the Fund. 
    

   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 Transfer Agent for 
investment in shares of the Fund. Shares purchased 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. 

   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. 

   
   Targeted Dividends. In states where it is legally permissible, 
shareholders may elect to have all shares of the Fund earned as a result of 
dividends paid in any given month redeemed as of the end of the month and 
invested in shares of any other open-end investment company for which 
InterCapital serves as investment manager (collectively, with the Fund, the 
"Dean Witter Funds"), other than Dean Witter Tax-Free Daily Income Trust, at 
the net asset value per share of the selected Dean Witter Fund determined as 
of the last business day of the month, without the imposition of any 
applicable front-end sales charge or without the imposition of any applicable 
contingent deferred sales charge upon ultimate redemption. All such shares 
invested will begin to earn dividends, if any, in the selected Dean Witter 
Fund on the first business day of the succeeding month. 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. 
    

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"), shares of Dean Witter Multi-State Municipal Series Trust and Dean 
Witter Hawaii Municipal Trust, which are Dean Witter Funds sold with a 
front-end sales charge ("FSC Funds"), and shares of Dean Witter Global 
Short-Term Income Fund Inc. ("Global Short-Term"), which is a Dean Witter 
Fund offered with a contingent deferred sales charge ("CDSC"), may be 
exchanged for shares of the Fund, Dean Witter U.S. Government Money Market 
Trust, Dean Witter California Tax-Free Daily Income Trust, Dean Witter New 
York Municipal Money Market and Dean Witter Liquid Asset Fund Inc. (which 
five Funds are called "money market funds"), and for shares of Dean Witter 
Short-Term U.S. Treasury Trust, Dean Witter Limited Term Municipal Trust, 
Dean Witter Short-Term Bond Fund and Dean Witter Intermediate Term U.S. 
Treasury Trust (which nine Funds, including the Fund, are referred to herein 
as the "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 

                               11           
    
<PAGE>
   
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 Global Short-Term. 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 Global Short-Term 
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. 

   When exchanging into a money market fund, shares of the Multi-Class Fund, 
the FSC Fund, Global Short-Term 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. 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. Ultimately, any applicable CDSC will have to be 
paid upon redemption of shares originally purchased from Global Short-Term 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 
Global Short-Term or Class B of a Dean Witter Multi-Class Fund are exchanged 
for shares of Global Short-Term or another Dean Witter Multi-Class Fund 
having a different CDSC schedule from that of Global Short-Term 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 Global Short-Term or from a Class 
of a Dean Witter Multi-Class Fund that imposes a CDSC remain in the Exchange 
Fund (calculated from the last day of the month in which the Exchange Fund 
shares were acquired), the holding period (for the purpose of determining the 
rate of the CDSC) is frozen. If those shares are subsequently reexchanged for 
shares of a Dean Witter Multi-Class Fund or Global Short-Term, the holding 
period previously frozen when the first exchange was made resumes on the last 
day of the month in which shares of a Dean Witter Multi-Class Fund or shares 
of Global Short-Term are reacquired. Thus, the CDSC is based upon the time 
(calculated as described above) the shareholder was invested in shares of a 
Dean Witter Multi-Class Fund or in shares of Global Short-Term. In the case 
of exchanges of Class A shares of a Dean Witter Multi-Class Fund that 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 distribution fees, if any, incurred on or after that 
date which are attributable to those shares (see "Purchase of Fund (Trust) 
Shares--Plan of Distribution" in the respective Exchange Fund Prospectus for 
a description 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. 
    

   Exchange Privilege accounts may also be maintained for shareholders of the 
money market funds who acquired their shares in exchange for shares of 
various TCW/DW Funds, a group of funds distributed by the Distributor for 
which TCW Funds Management, Inc. serves as Adviser, under the terms and 
conditions described in the Prospectus and Statement of Additional 
Information of each TCW/DW Fund. 

   
   Additional Information Regarding Exchanges. Purchases and exchanges should 
be made for investment purposes only. A pattern of frequent 
    

                               12           
<PAGE>
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 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 Exchange 
Funds or TCW/DW North American Government Income Trust pursuant to the 
Exchange Privilege, and provided further that the Exchange Privilege may be 
terminated or materially revised without notice under certain unusual 
circumstances described in the Statement of Additional Information. 
Shareholders maintaining margin accounts with DWR or other Selected 
Broker-Dealers are referred to their account executive regarding restrictions 
on exchanges 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 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 
Funds pursuant to this Exchange Privilege by contacting their DWR or another 
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 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 

                               13           
<PAGE>
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 this 
Fund and the other Dean Witter Funds in the past. 

   Shareholders should contact their DWR or other Selected Broker-Dealer 
account executive or the Transfer Agent, for further information about the 
Exchange Privilege. 

   
REDEMPTION OF FUND SHARES 
- ----------------------------------------------------------------------------- 
    

   A shareholder may withdraw all or any of his or her investments at any 
time, without penalty or charge, by redeeming shares through the Transfer 
Agent at the net asset value per share next determined (see "Purchase of Fund 
Shares--Determination of Net Asset Value") after the receipt of a redemption 
request meeting the applicable requirements as follows (all of which are 
subject to the General Redemption Requirements set forth 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 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. 

   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. 

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 telephone or wire instructions. 

   DWR and 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 Trans- 

                               14           
<PAGE>
fer Agent will wire proceeds of redemptions to DWR's or another 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 share-holder's name and account 
number and be wired or called to the Transfer Agent: 

   --800-869-NEWS (Toll-Free) 

   --Telex No. 125076 

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. 

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 an eligible guarantor), except in the 
case of redemption by check. Additional documentation may be required where 
shares are held by a corporation, partnership, trustee or executor. With 
regard to shares of the Fund acquired pursuant to the Exchange Privilege, any 
applicable CDSC 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 accompanied by the share certificate and a 
share assignment form signed by the registered share-holder(s) exactly as the 
account is registered. Shareholders are advised, for their own protection, to 
send the share certificate and assignment form in separate envelopes (if they 
are being mailed and not hand delivered) to the Transfer Agent. Signatures 
must be guaranteed by an eligible guarantor acceptable to the Transfer Agent 
(see above). Additional documentation may be required where shares are held 
by a corporation, partnership, trustee or executor. 

   
   All requests for redemption, all share certificates and all share 
assignments 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, but 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 investment 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. 

   The Fund reserves the right, on sixty days notice, to redeem at net asset 
value the shares of any shareholder (other than shares held in an Individual 
Retirement Account or custodial account under Section 403(b)(7) of the 
Internal Revenue Code) whose shares due to redemptions by the shareholder 
have a value of less than $1,000, or such lesser amount as may be fixed by 
the Board of Trustees. 

AUTOMATIC REDEMPTION PROCEDURE 

   The Distributor has instituted an automatic redemption procedure which it 
may utilize to satisfy amounts due by a shareholder maintaining a bro- 

                               15           
<PAGE>
kerage account with DWR or another Selected Broker-Dealer, as a result of 
purchases of securities or other transactions in the shareholder's brokerage 
account. Under this procedure, if the shareholder elects to participate by so 
notifying DWR or other Selected Broker-Dealer, the shareholder's DWR or other 
Selected Broker-Dealer brokerage account will be scanned each business day 
prior to the close of business (4:00 p.m., New York time). After application 
of any cash balances in the account, a sufficient number of Fund shares may 
be redeemed at the close of business to satisfy any amounts for which the 
shareholder is obligated to make payment to DWR or another Selected 
Broker-Dealer. Redemptions will be effected on the business day preceding the 
date the shareholder is obligated to make such payment, and DWR or another 
Selected Broker-Dealer will receive the redemption proceeds on the day 
following the redemption date. Shareholders will receive all dividends 
declared and reinvested through the date of redemption. 

   
EASYINVEST (SERVICE MARK) -- AUTOMATIC REDEMPTION 

   Shareholders may invest in shares of certain other Dean Witter Funds by 
subscribing to Easy- Invest, an automatic purchase plan which provides for 
the automatic investment of any amount from $100 to $5,000 in shares of the 
specified fund. Under EasyInvest, a shareholder may direct that a sufficient 
number of shares of the Fund be automatically redeemed and the proceeds 
transferred automatically to the Dean Witter Funds' Transfer Agent, on a 
semi-monthly, monthly or quarterly basis, for investment in shares of the 
specified fund. Redemptions will be effected on the business day preceding 
the investment date and the Transfer Agent will receive the proceeds for 
investment on the day following the redemption date. 
    

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

   
   Dividends and Distributions. The Fund declares dividends, payable on each 
day the New York Stock Exchange is open for business, of all of its daily net 
investment income to shareholders of record as of the close of business the 
preceding business day. Dividends from net short-term capital gains, if any, 
will be paid periodically. Dividends from net long-term capital gains, if 
any, will be paid annually. The amount of dividend may fluctuate from day to 
day and may be omitted on some days if net realized losses on portfolio 
securities exceed the Fund's net investment income. Dividends are declared 
and automatically reinvested daily in additional full and fractional shares 
of the Fund (rounded to the last 1/100 of a share) at the net asset value per 
share at the close of business on that day. Any dividends 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 monthly in cash. For such shareholders, the shares 
reinvested and credited to their account during the month will be redeemed as 
of the close of business on the monthly payment date (which will be no later 
than the last business day of the month) and the proceeds will be paid to 
them by check. 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. 

   Share certificates for dividends or distributions will not be issued 
unless a shareholder requests in writing that a certificate be issued for a 
specific number of shares. 

   
   Taxes. Because the Fund intends to distribute substantially all of its net 
investment income and net short-term 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, 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, 

                               16           
<PAGE>
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 satisfies 
such requirement, distributions 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. A portion of the Fund's investments may be made 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 tax able income. 

   
   Shareholders will be subject to federal income tax on dividends paid from 
interest income derived from taxable securities and on distributions of net 
short-term capital gains, if any. Such dividends and distributions are 
taxable to the shareholder as ordinary income. Distributions of net long-term 
capital gains, if any, are taxable as net long-term capital gains, regardless 
of how long the 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 dividends or distributions will be eligible for the federal 
dividends received deduction for corporations. 

   After the end of its calendar year, the shareholders will be sent a 
statement indicating the percentage of the dividend distributions for such 
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 constitute an item of tax preference. This percentage should 
be applied uniformly to any distributions made during the taxable year to 
determine the proportion of dividends that is tax-exempt. The percentage may 
differ from the percentage of tax-exempt dividend distributions for any 
particular month. 
    

   The exemption of interest income for federal income tax purposes does not 
necessarily result in exemption under the income or other tax laws of any 
state or local taxing authority. Thus, shareholders of the Fund may be 
subject to state and local taxes on exempt-interest dividends. 

   The Fund advises its shareholders annually as to the federal income tax 
status of distributions paid during each calendar year. To avoid being 
subject to a 31% federal withholding tax on taxable dividends, capital gains 
distributions and proceeds of redemptions, shareholders' taxpayer 
identification numbers must be furnished and certified as to accuracy. 

   Shareholders should consult their tax advisers as to the applicability of 
the above to their own tax situation. 

CURRENT AND EFFECTIVE YIELD 

   
   From time to time the Fund advertises its "yield" and "effective yield." 
Both yield figures are based on historical earnings and are not intended to 
indicate future performance. The "yield" of the Fund refers to the income 
generated by an investment in the Fund over a given seven-day period (which 
period will be 
    

                               17           
<PAGE>
stated in the advertisement). This income is then "annualized." That is, the 
amount of income generated by investment during that seven-day period is 
assumed to be generated each seven-day period within a 365-day period and is 
shown as a percentage of the investment. The "effective yield" for a 
seven-day period is calculated similarly but, when annualized, the income 
earned by an investment in the Fund is assumed to be reinvested each week 
within a 365-day period. The "effective yield" will be slightly higher than 
the "yield" because of the compounding effect of this assumed reinvestment. 
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 Fund may also advertise the growth of hypothetical investments of 
$10,000, $50,000 and $100,000 in shares of the Fund. 

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. 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. Under certain 
circumstances, the Trustees may be removed by action of the Trustees or by 
the shareholders. 

   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 
notice of such disclaimer be given in each instrument entered into or 
executed by the Fund 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 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 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

objectives by investing all of its investable assets in a diversified, 
open-end management investment company having the same investment objectives 
and policies and substantially the same investment restrictions as those 
applicable to the Fund. 

   Year 2000. The investment management services provided to the Fund by the 
Investment Manager and the services provided to shareholders by the 
Distributor and the Transfer Agent depend on the smooth functioning of their 
computer systems. Many computer software systems in use today cannot 
recognize the year 2000, but revert to 1900 or some other date, due to the 
manner in which dates were encoded and calculated. That failure could have a 
negative impact on the handling of securities trades, pricing and account 
services. The Investment Manager, the Distributor and the Transfer Agent have 
been actively working on necessary changes to their own computer systems to 
prepare for the year 2000 and expect that their systems will be adapted 
before that date, but there can be no assurance that they will be successful, 
or that interaction with other non-complying computer systems will not impair

DEAN WITTER TAX-FREE DAILY INCOME TRUST 
NOTES TO FINANCIAL STATEMENTS December 31, 1997 

1. ORGANIZATION AND ACCOUNTING POLICIES 

Dean Witter Tax-Free Daily Income Trust (the "Fund") is registered under the 
Investment Company Act of 1940, as amended (the "Act"), as a diversified, 
open-end management investment company. The Fund's investment objective is to 
provide a high level of daily income which is exempt from federal income tax, 
consistent with stability of principal and liquidity. The Fund was 
incorporated in Maryland in 1980, commenced operations on February 20, 1981 
and reorganized as a Massachusetts business trust on April 30, 1987. 

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

The following is a summary of significant accounting policies: 

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

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

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

D. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- The Fund records dividends 
and distributions to shareholders as of the close of each business day. 

2. INVESTMENT MANAGEMENT AGREEMENT 

Pursuant to an Investment Management Agreement with Dean Witter InterCapital 
Inc. (the "Investment Manager"), the Fund pays the Investment Manager a 
management fee, accrued daily and payable monthly, by applying the following 
annual rates to the net assets of the Fund determined as of the close of each 
business day: 0.50% to the portion of the daily net assets not exceeding $500 
million; 0.425% to the portion of the daily net assets exceeding $500 million 
but not exceeding $750 million; 0.375% to the portion of the daily net assets 
exceeding $750 million but not exceeding $1 billion; 0.35% to the portion of

DEAN WITTER TAX-FREE DAILY INCOME TRUST 
NOTES TO FINANCIAL STATEMENTS December 31, 1997, continued 
   
the daily net assets exceeding $1 billion but not exceeding $1.5 billion; 
0.325% to the portion of the daily net assets exceeding $1.5 billion but not 
exceeding $2 billion; 0.30% to the portion of the daily net assets exceeding 
$2 billion but not exceeding $2.5 billion; 0.275% to the portion of the daily 
net assets exceeding $2.5 billion but not exceeding $3 billion; and 0.25% to 
the portion of the daily net assets exceeding $3 billion. 

Under the terms of the Agreement, in addition to managing the Fund's 
investments, the Investment Manager maintains certain of the Fund's books and 
records and furnishes, at its own expense, office space, facilities, 
equipment, clerical, bookkeeping and certain legal services and pays the 
salaries of all personnel, including officers of the Fund who are employees 
of the Investment Manager. The Investment Manager also bears the cost of 
telephone services, heat, light, power and other utilities provided to the 
Fund. 

3. PLAN OF DISTRIBUTION 

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

Under the Plan, the Distributor bears the expense of all promotional and 
distribution related activities on behalf of the Fund, except for expenses 
that the Trustees determine to reimburse, as described below. The following 
activities and services may be provided by the Distributor and other

DEAN WITTER TAX-FREE DAILY INCOME TRUST 
REPORT OF INDEPENDENT ACCOUNTANTS 

   
TO THE SHAREHOLDERS AND TRUSTEES 
OF DEAN WITTER TAX-FREE DAILY INCOME TRUST 

In our opinion, the accompanying statement of assets and liabilities, 
including the portfolio of investments, and the related statements of 
operations and of changes in net assets and the financial highlights 
(appearing in the "Financial Highlights" table on page 4 of this Prospectus) 
present fairly, in all material respects, the financial position of Dean 
Witter Tax-Free Daily Income Trust (the "Fund") at December 31, 1997, the 
results of its operations for the year then ended, the changes in its net 
assets for each of the two years in the period then ended and the financial 
highlights for each of the ten years in the period then ended, in conformity 
with generally accepted accounting principles. These financial statements and 
financial highlights (hereafter referred to as "financial statements") are 
the responsibility of the Fund's management; our responsibility is to express 
an opinion on these financial statements based on our audits. We conducted 
our audits of these financial statements in accordance with generally 
accepted auditing standards which require that we plan and perform the audit 
to obtain reasonable assurance about whether the financial statements are 
free of material misstatement. An audit includes examining, on a test basis, 
evidence supporting the amounts and disclosures in the financial statements, 
assessing the accounting principles used and significant estimates made by 
management, and evaluating the overall financial statement presentation. We 
believe that our audits, which included confirmation of securities at 
December 31, 1997 by correspondence with the custodian, provide a reasonable 
basis for the opinion expressed above.

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

THE FUND 

   The Fund was incorporated in the state of Maryland on March 24, 1980 under 
the name InterCapital Reserve Cash Management Inc. From May 19, 1980 to 
August 15, 1980, the Fund was engaged in operations as a publicly held, 
open-end investment company of the type commonly known as a money market 
fund. On August 15, 1980, the Fund terminated its operations as a money 
market fund in response to changes in regulations promulgated by the Federal 
Reserve Board. At that time, substantially all of the Fund's assets were 
transferred to lnterCapital Liquid Asset Fund Inc., another money market 
fund, as part of an offer of exchange made to the Fund's shareholders. On 
October 13, 1980 the Fund's sole remaining shareholder, Dean Witter Reynolds 
InterCapital Inc. ("InterCapital"), approved a change in the Fund's name to 
lnterCapital Tax-Free Daily Income Fund Inc. and an amendment to the Fund's 
investment objective and fundamental investment policies to those set forth 
in the Prospectus and this Statement of Additional Information. The Fund 
offered its shares for sale to the public, commencing on February 20, 1981. 
On March 21, 1983 the Fund's name was changed to Dean Witter/Sears Tax-Free 
Daily Income Fund Inc. On April 30, 1987, the Fund reorganized as a 
Massachusetts business trust with the name Dean Witter/Sears Tax-Free Daily 
Income Trust. On February 19, 1993, the Fund's name was changed to its 
current name, Dean Witter Tax-Free Daily Income Trust. 

   
   As of December 31, 1997 no shareholder was known to own beneficially or of 
record as much as 5% of the outstanding shares of the Fund. The percentage of 
ownership of shares of the Fund changes from time to time depending on 
purchases and redemptions by shareholders and the total number of shares 
outstanding. 
    

THE INVESTMENT MANAGER 

   
   Dean Witter InterCapital Inc., a Delaware corporation (the "Investment 
Manager" or "InterCapital"), whose address is Two World Trade Center, New 
York, New York 10048, is the Fund's Investment Manager. InterCapital is a 
wholly-owned subsidiary of Morgan Stanley, Dean Witter, Discover & Co. 
("MSDWD"), a Delaware corporation. In an internal reorganization which took 
place in January, 1993, InterCapital assumed the investment advisory, 
administrative and management activities previously performed by the 
InterCapital Division of Dean Witter Reynolds Inc. ("DWR"), a broker-dealer 
affiliate of InterCapital. (As hereinafter used in this Statement of 
Additional Information, the terms "InterCapital" and "Investment Manager" 
refer to DWR's InterCapital Division prior to the internal reorganization and 
to Dean Witter InterCapital Inc. thereafter.) The daily management of the 
Fund and research relating to the Fund's portfolio is conducted by or under 
the direction of officers of the Fund and of the Investment Manager, subject 
to review by the Fund's Board of Trustees. Information as to these Trustees

Fund, mutual funds established under the laws of the Cayman Islands and 
available only to investors who are participants in DWR's International 
Active Assets Account program and are neither citizens nor residents of the 
United States. 
    

   Pursuant to an Investment Management Agreement (the "Agreement") with the 
Investment Manager, the Fund has retained the Investment Manager to manage 
the investment of the Fund's assets, including the placing of orders for the 
purchase and sale of portfolio securities. The Investment Manager obtains and 
evaluates such information and advice relating to the economy, securities 
markets, and specific securities as it considers necessary or useful to 
continuously manage the assets of the Fund in a manner consistent with its 
investment objective and policies. 

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

                                4

   Effective December 31, 1993, pursuant to a Services Agreement between 
InterCapital and DWSC, DWSC began to provide the administrative services to 
the Fund which were previously performed directly by InterCapital. On April 
17, 1995, DWSC was reorganized in the State of Delaware, necessitating the 
entry into a new Services Agreement by InterCapital and DWSC on that date. 
The foregoing internal reorganizations did not result in any change in the 
nature or scope of the administrative services being provided to the Fund or 
any of the fees being paid by the Fund for the overall services being 
performed under the terms of the existing Management Agreement. 

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

   As full compensation for the services and facilities furnished to the Fund 
and expenses of the Fund assumed by the Investment Manager, the Fund pays the 
Investment Manager monthly compensation calculated daily by applying the 
following annual rates to the net assets of the Fund, determined as of the 
close of each business day: 0.50% of the portion of the daily net assets not 
exceeding $500 million; 0.425% of the portion of the daily net assets 
exceeding $500 million but not exceeding $750 million; 0.375% of the portion 
of the daily net assets exceeding $750 million but not exceeding $1 billion; 
0.35% of the portion of the daily net assets exceeding $1 billion but not 
exceeding $1.5 billion; 0.325% of the portion of the daily net assets 
exceeding $1.5 billion but not exceeding $2 billion; 0.30% of the portion of 
the daily net assets exceeding $2 billion but not exceeding $2.5 billion; 
0.275% of the portion of the daily net assets exceeding $2.5 billion but not 
exceeding $3 billion; and 0.25% of the portion of the daily net assets 
exceeding $3 billion. For the fiscal years ended December 31, 1995, December 
31, 1996 and December 31, 1997, the Fund accrued to the Investment Manager 
total compensation of $2,793,438, $2,738,887 and $2,695,933, respectively. 
    

   The Agreement provides that in the absence of willful misfeasance, bad 
faith, gross negligence or reckless disregard of its obligations thereunder, 
the Investment Manager is not liable to the Fund or any of its investors for 
any act or omission by the Investment Manager or for any losses sustained by 
the Fund or its investors. The Agreement in no way restricts the Investment 
Manager from acting as investment manager or adviser to others. 

   
   The Agreement was initially approved by the Trustees on February 21, 1997 
and by the shareholders of the Fund at a Meeting of Shareholders held on May 
21, 1997. The Agreement is substantially identical to a prior investment 
management agreement which was initially approved by the Trustees on October 
30, 1992, and by the shareholders of the Fund at a Special Meeting of 
Shareholders held on January 12, 1993. The Agreement took effect on May 31, 
1997 upon the consummation of the merger of Dean Witter, Discover & Co. with 
Morgan Stanley Group Inc. The Agreement may be

terminated at any time, without penalty, on thirty days notice, by the Board 
of Trustees of the Fund, by the holders of a majority, as defined in the 
Investment Company Act of 1940, as amended (the "Act"), of the outstanding 
shares of the Fund, or by the Investment Manager. 

   Under its terms, the Agreement has an initial term ending April 30, 1999, 
and will continue in effect from year to year thereafter, provided 
continuance of the Agreement is approved at least annually by the vote of the 
holders of a majority (as defined in the Act) of the outstanding shares of 
the Fund, or by the Board of Trustees of the Fund; provided that in either 
event such continuance is approved annually by the vote of a majority of the 
Trustees of the Fund who are not parties to the Agreement or "interested 
persons" (as defined in the Act) of any such party (the "Independent 
Trustees"), which vote must be cast in person at a meeting called for the 
purpose of voting on such approval. 
    

   The Fund has acknowledged that the name "Dean Witter" is a property right 
of DWR. The Fund has agreed that DWR or its parent company may use, or at any 
time, permit others to use, the name "Dean Witter." The Fund has also agreed 
that in the event the Agreement is terminated, or if the affiliation between 
InterCapital and its parent is terminated, the Fund will eliminate the name 
"Dean Witter" from its name if DWR or its parent shall so request.

THE BOARD OF TRUSTEES, THE INDEPENDENT TRUSTEES, AND THE COMMITTEES 

   
   The Board of Trustees consists of nine (9) trustees. These same 
individuals also serve as directors or trustees for all of the Dean Witter 
Funds, and are referred to in this section as Trustees. As of the date of 
this Statement of Additional Information, there are a total of 84 Dean Witter 
Funds, comprised of 128 portfolios. As of January 31, 1998, the Dean Witter 
Funds had total net assets of approximately $96 billion and more than five 
million shareholders. 

   Seven Trustees (77% of the total number) have no affiliation or business 
connection with InterCapital or any of its affiliated persons and do not own 
any stock or other securities issued by InterCapital's parent company, MSDWD. 
These are the "disinterested" or "independent" Trustees. The other two 
Trustees (the "management Trustees") are affiliated with InterCapital. Four 
of the seven independent Trustees are also Independent Trustees of the TCW/DW 
Funds. 
    

   Law and regulation establish both general guidelines and specific duties 
for the Independent Trustees. The Dean Witter Funds seek as Independent 
Trustees individuals of distinction and experience in business and finance, 
government service or academia; these are people whose advice and counsel are 
in demand by others and for whom there is often competition. To accept a 
position on the Funds' Boards, such individuals may reject other attractive 
assignments because the Funds make substantial demands on their time. Indeed, 
by serving on the Funds' Boards, certain Trustees who would otherwise be 
qualified and in demand to serve on bank boards would be prohibited by law 
from doing so. 

   
   All of the Independent Trustees serve as members of the Audit Committee 
and the Committee of the Independent Trustees. Three of them also serve as 
members of the Derivatives Committee. During the calendar year ended December 
31, 1997, the three Committees held a combined total of seventeen meetings. 
The Committees hold some meetings at InterCapital's offices and some outside 
InterCapital. Management Trustees or officers do not attend these meetings 
unless they are invited for purposes of furnishing information or making a 
report. 
    

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

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

   Finally, the Board of each Fund has formed a Derivatives Committee to 
establish parameters for and oversee the activities of the Fund with respect 
to derivative investments, if any, made by the Fund.

DUTIES OF CHAIRMAN OF COMMITTEE OF THE INDEPENDENT TRUSTEES AND AUDIT 
COMMITTEE 

   The Chairman of the Committee of the Independent Trustees and the Audit 
Committee maintains an office at the Funds' headquarters in New York. He is 
responsible for keeping abreast of regulatory and industry developments and 
the Funds' operations and management. He screens and/or prepares written 
materials and identifies critical issues for the Independent Trustees to 
consider, develops agendas for Committee meetings, determines the type and 
amount of information that the Committees will need to form a judgment on 
various issues, and arranges to have that information furnished to Committee 
members. He also arranges for the services of independent experts and 
consults with them in advance of meetings to help refine reports and to focus 
on critical issues. Members of the Committees believe that the person who 
serves as Chairman of both Committees and guides their efforts is pivotal to 
the effective functioning of the Committees. 

   The Chairman of the Committees also maintains continuous contact with the 
Funds' management, with independent counsel to the Independent Trustees and 
with the Funds' independent auditors. He arranges for a series of special 
meetings involving the annual review of investment advisory, management and 
other operating contracts of the Funds and, on behalf of the Committees, 
conducts negotiations with the Investment Manager and other service 
providers. In effect, the Chairman of the Committees serves as a combination 
of chief executive and support staff of the Independent Trustees. 

   
   The Chairman of the Committee of the Independent Trustees and the Audit 
Committee is not employed by any other organization and devotes his time 
primarily to the services he performs as Committee Chairman and Independent 
Trustee of the Dean Witter Funds and as an Independent Trustee and as 
Chairman of the Committee of the Independent Trustees and the Audit Committee 
of the TCW/DW Funds. The current Committee Chairman has had more than 35 
years experience as a senior executive in the investment company industry. 
    

ADVANTAGES OF HAVING SAME INDIVIDUALS AS INDEPENDENT TRUSTEES FOR ALL DEAN 
WITTER FUNDS 

   The Independent Trustees and the Funds' management believe that having the 
same Independent Trustees for each of the Dean Witter Funds avoids the 
duplication of effort that would arise from having different groups of 
individuals serving as Independent Trustees for each of the Funds or even of 
sub-groups of Funds. They believe that having the same individuals serve as 
Independent Trustees of all the Funds tends to increase their knowledge and 
expertise regarding matters which affect the Fund complex generally and 
enhances their ability to negotiate on behalf of each Fund with the Fund's 
service providers. This arrangement also precludes the possibility of 
separate groups of Independent Trustees arriving at conflicting decisions 
regarding operations and management of the Funds and avoids the cost and 
confusion that would likely ensue. Finally, having the same Independent 
Trustees serve on all Fund Boards enhances the ability of each Fund to 
obtain, at modest cost to each separate Fund, the services of Independent 
Trustees, and a Chairman of their Committees, of the caliber, experience and 
business acumen of the individuals who serve as Independent Trustees of the 
Dean Witter Funds. 

COMPENSATION OF INDEPENDENT TRUSTEES 

   
   The Fund pays each Independent Trustee an annual fee of $800 plus a per 
meeting fee of $50 for meetings of the Board of Trustees or committees of the 
Board of Trustees attended by the Trustee (the Fund pays the Chairman of the 
Audit Committee an annual fee of $750 and pays the Chairman of the Committee 
of the Independent Trustees an additional annual fee of $1,200). If a Board 
meeting and a Committee meeting, or more than one Committee meeting, take 
place on a single day, the Trustees are paid a single meeting fee by the 
Fund. The Fund also reimburses such Trustees for travel and other 
out-of-pocket expenses incurred by them in connection with attending such 
meetings. Trustees and officers of the Fund who are or have been employed by 
the Investment Manager or an affiliated company receive no compensation or 
expense reimbursement from the Fund.

   As of the date of this Statement of Additional Information, 57 of the Dean 
Witter Funds, including the Fund, have adopted a retirement program under 
which an Independent Trustee who retires after serving for at least five 
years (or such lesser period as may be determined by the Board) as an 
Independent Director or Trustee of any Dean Witter Fund that has adopted the 
retirement program (each such Fund referred to as an "Adopting Fund" and each 
such Trustee referred to as an "Eligible Trustee") is entitled to retirement 
payments upon reaching the eligible retirement age (normally, after attaining 
age 72). Annual payments are based upon length of service. Currently, upon 
retirement, each Eligible Trustee is entitled to receive from the Adopting 
Fund, commencing as of his or her retirement date and continuing for the 
remainder of his or her life, an annual retirement benefit (the "Regular 
Benefit") equal to 25.0% of his or her Eligible Compensation plus 0.4166666% 
of such Eligible Compensation for each full month of service as an 
Independent Director or Trustee of any Adopting Fund in excess of five years 
up to a maximum of 50.0% after ten years of service. The foregoing 
percentages may be changed by the Board.(1) "Eligible Compensation" is 
one-fifth of the total compensation earned by such Eligible Trustee for 
service to the Adopting Fund in the five year period prior to the date of the 
Eligible Trustee's retirement. Benefits under the retirement program are not 
secured or funded by the Adopting Funds. 
- ---------------
(1)    An Eligible Trustee may elect alternate payments of his or her 
       retirement benefits based upon the combined life expectancy of such 
       Eligible Trustee and his or her spouse on the date of such Eligible 
       Trustee's retirement. The amount estimated to be payable under this 
       method, through the remainder of the later of the lives of such 
       Eligible Trustee and spouse, will be the actuarial equivalent of the 
       Regular Benefit. In addition, the Eligible Trustee may elect that the 
       surviving spouse's periodic payment of benefits will be equal to either 
       50% or 100% of the previous periodic amount, an election that, 
       respectively, increases or decreases the previous periodic amount so 
       that the resulting payments will be the actuarial equivalent of the 
       Regular Benefit.

INVESTMENT PRACTICES AND POLICIES 
- ----------------------------------------------------------------------------- 

PORTFOLIO SECURITIES 
    

   Municipal Bonds. Municipal Bonds, as referred to in the Prospectus, are 
debt obligations of states, cities, municipalities and municipal agencies 
(all of which are generally referred to as "municipalities") which generally 
have a maturity at the time of their issuance of one year or more. They are 
issued to raise funds for various public purposes, such as construction of a 
wide range of public facilities, to refund outstanding obligations and to 
obtain funds for general operating expenses or to loan to other public 
institutions and facilities. In addition, certain types of industrial 
development bonds and pollution control bonds are issued by or on behalf of 
public authorities to provide funding for various privately operated 
facilities. 

   Municipal Notes. Municipal Notes are short-term obligations of 
municipalities, generally with a maturity, at the time of issuance, ranging 
from six months to three years the interest from which is, in the opinion of 
bond counsel, exempt from federal income tax. The principal types of 
Municipal Notes include tax anticipation notes, bond anticipation notes, 
revenue anticipation notes and project notes, although there are other types 
of Municipal Notes in which the Fund may invest. Notes sold in anticipation 
of collection of taxes, a bond sale, or receipt of other revenues are usually 
general obligations of the issuing municipality or agency. Project Notes are 
issued by local agencies and are guaranteed by the United States Department 
of Housing and Urban Development. Such notes are secured by the full faith 
and credit of the United States. Project notes are not currently being 
issued. 

   Municipal Commercial Paper. Municipal Commercial Paper refers to 
short-term obligations of municipalities the interest from which is, in the 
opinion of bond counsel, exempt from federal income tax, and which may be 
issued at discount and are sometimes referred to as Short-Term Discount 
Notes. They 

                               12           
<PAGE>
are likely to be used to meet seasonal working capital needs of a 
municipality or interim construction financing and to be paid from general 
revenues of the municipality or refinanced with long-term debt. In most 
cases, Municipal Commercial Paper is backed by letters of credit, lending 
agreements, note repurchase agreements or other credit facility agreements 
offered by banks or other institutions. 

   The two principal classifications of Municipal Bonds, Municipal Notes and 
Municipal Commercial Paper are "general obligation" and "revenue" bonds, 
notes or commercial paper. General obligation bonds, notes and 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 and commercial paper include states, counties, 
cities, towns and other governmental units. Revenue bonds, notes and 
commercial paper are payable from the revenues derived from a particular 
facility or class of facilities and, in some cases, from specific revenue 
sources. Revenue bonds, notes and 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 
in the instance of 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. 

   Obligations of issuers of Municipal Bonds, Municipal Notes and Municipal 
Commercial Paper are subject to the provisions of bankruptcy, insolvency and 
other laws affecting the rights and remedies of creditors, such as the 
Federal Bankruptcy Act, and laws, if any, which may be enacted by Congress or 
state legislatures to extend the time for payment of principal or interest, 
or both, or to impose other constraints upon enforcement of such obligations 
or upon municipalities to levy taxes. There is also the possibility that, as 
a result of litigation or other conditions, the power or ability of any one 
or more issuer to pay, when due, principal of and interest on its, or their, 
Municipal Bonds, Municipal Notes and Municipal Commercial Paper may be 
materially affected. 

PORTFOLIO MANAGEMENT 

   Variable Rate and Floating Rate Obligations. As stated in the Prospectus, 
the Fund may invest in Municipal Bonds and Municipal Notes ("Municipal 
Obligations") of the type called variable rate and floating rate obligations. 
The interest rate payable on a variable rate obligation is adjusted either at 
predesignated periodic intervals and, on a floating rate obligation, whenever 
there is a change in the market rate of interest on which the interest rate 
payable is based. Other features may include the right whereby the Fund may 
demand prepayment of the principal amount of the obligation prior to its 
stated maturity (a "demand feature") and the right of the issuer to prepay 
the principal amount prior to maturity. The principal benefit of a variable 
rate obligation is that the interest rate adjustment minimizes changes in the 
market value of the obligation. As a result, the purchase of variable rate 
and floating rate obligations could enhance the ability of the Fund to 
maintain a stable net asset value per share (see "Purchase of Fund 
Shares--Determination of Net Asset Value" in the Prospectus) and to sell 
obligations prior to maturity at a price approximately the full principal 
amount of the obligations. The principal benefit to the Fund of purchasing 
obligations with a demand feature is that liquidity, and the ability of the 
Fund to obtain repayment of the full principal amount of an obligation prior 
to maturity, is enhanced. The payment of principal and interest by issuers of 
certain obligations purchased by the Fund may be guaranteed by letters of 
credit or other credit facilities offered by banks or other financial 
institutions. Such guarantees will be considered in determining whether an 
obligation meets the Fund's investment quality requirements. 

   When-Issued and Delayed Delivery Securities. As stated in the Prospectus, 
the Fund may purchase tax-exempt securities on a when-issued or delayed 
delivery basis. When such transactions are negotiated, the price is fixed at 
the time of commitment, but delivery and payment can take place a month 

                               13           
<PAGE>
   
or more after the date of the commitment. While the Fund will only purchase 
securities on a when-issued or delayed delivery 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 a Municipal Obligation on a when-issued or delayed delivery basis, 
it will record the transaction and thereafter reflect the value, each day, of 
the Municipal Obligation in determining its net asset value. The Fund will 
also establish a segregated account with its custodian bank in which it will 
maintain cash, cash equivalents or other liquid portfolio securities equal in 
value to commitments for such when-issued or delayed delivery securities. The 
Fund does not believe that its net asset value or income will be adversely 
affected by its purchase of Municipal Obligations on a when-issued or delayed 
delivery basis. During the fiscal year ended December 31, 1997, the Fund's 
investments in when-issued and delayed delivery securities did not exceed 5% 
of the Fund's net assets. 
    

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

   
   While the repurchase agreements involve certain risks not associated with 
direct investments in debt securities, the Fund follows procedures designed 
to minimize such risks. These procedures include effecting repurchase 
transactions only with large, well capitalized and well established financial 
institutions, whose financial condition will be continually monitored by the 
Investment Manager. In addition, the value of the collateral underlying the 
repurchase agreement will always be at least equal to the resale price which 
consists of the purchase price paid to the seller of the securities plus the 
accrued resale premium which is defined as the amount specified in the 
repurchase agreement or the daily amortization of the difference between the 
purchase price and the resale price specified in the repurchase agreement. 
Such collateral will consist entirely of securities that are direct 
obligations of, or that are fully guaranteed as to principal and interest by, 
the United States or any agency thereof, and/or certificates of deposit, 
bankers' acceptances which are eligible for acceptance by a Federal Reserve 
Bank, and, if the seller is a bank, mortgage related securities (as such term 
is defined in section 3(a)(41) of the Securities Exchange Act of 1934) that, 
at the time the repurchase agreement is entered into, are rated in the 
highest rating category by the Requisite NRSROs. Additionally, the collateral 
must qualify the repurchase agreement for preferential treatment under the 
Federal Deposit Insurance Act or the Federal Bankruptcy Code. In the event of 
a default or bankruptcy by a selling financial institution, the Fund will 
seek to liquidate such collateral. However, the exercise of the Fund's right 
to liquidate such collateral could involve certain costs or delays and, to 
the extent that proceeds from any sale upon a default of the obligation to 
repurchase were less than the repurchase price, the Fund could suffer a loss. 
It is the current policy of the Fund not to invest in repurchase agreements 
that do not mature within seven days if any such investment, together with 
any other illiquid asset held by the Fund, amount to more than 10% of its 
total net assets. The Fund's investments in repurchase agreements may, at 
times, be substantial when, in the view of the Investment Manager, liquidity 
or other considerations warrant. However, during the fiscal year ended 
December 31, 1997, the Fund did not enter into any repurchase agreements. 
    

   Put Options. The Fund may purchase securities together with the right to 
resell them to the seller at an agreed upon price or yield within a specified 
period prior to the maturity date of such securities. Such a right to resell 
is commonly known as a "put," and the aggregate price which the Fund pays for 
securities with puts may be higher than the price which otherwise would be 
paid for the securities. Consistent with the Fund's investment objectives and 
subject to the supervision of the Board of Trustees, 

                               14           
<PAGE>
the primary purpose of this practice is to permit the Fund to be fully 
invested in securities the interest on which is exempt from Federal income 
tax while preserving the necessary flexibility and liquidity to purchase 
securities on a when-issued basis, or to meet unusually large redemptions and 
to purchase at a later date securities other than those subject to the put. 
The Fund's policy is, generally, to exercise the puts on their expiration 
date, when the exercise price is higher than the current market price for the 
related securities. Puts may be exercised prior to the expiration date in 
order to fund obligations to purchase other securities or to meet redemption 
requests. These obligations may arise during the periods in which proceeds 
from sales of Fund shares and from recent sales of portfolio securities are 
insufficient to meet such obligations or when the funds available are 
otherwise allocated for investment. In addition, puts may be exercised prior 
to their expiration date in the event the Investment Manager revises its 
evaluation of the creditworthiness of the issuer of the underlying security. 
In determining whether to exercise puts prior to their expiration date and in 
selecting which puts to exercise in such circumstances, the Investment 
Manager considers, among other things, the amount of cash available to the 
Fund, the expiration dates of the available puts, any future commitments for 
securities purchases, the yield, quality and maturity dates of the underlying 
securities, alternative investment opportunities and the desirability of 
retaining the underlying securities in the Fund's portfolio. 

   
   The Fund values securities which are subject to puts at their amortized 
cost and values the put, apart from the security, at zero. Thus, the cost of 
the put will be carried on the Fund's books as an unrealized loss from the 
date of acquisition and will be reflected in realized gain or loss when the 
put is exercised or expires. Since the value of the put is dependent on the 
ability of the put writer to meet its obligation to repurchase, the Fund's 
policy is to enter into put transactions only with municipal securities 
dealers who are approved by the Fund's Board of Trustees. Each dealer will be 
approved on its own merits and it is the Fund's general policy to enter into 
put transactions only with those dealers which are determined to present 
minimal credit risks. In connection with such determination, the Board of 
Trustees will review, among other things, the ratings, if available, of 
equity and debt securities of such municipal securities dealers, their 
reputations in the municipal securities markets, the net worth of such 
dealers and their efficiency in consummating transactions. Bank dealers 
normally will be members of the Federal Reserve System, and other dealers 
will be members of the National Association of Securities Dealers, Inc. or 
members of a national securities exchange. The Board has directed the 
Investment Manager not to enter into put transactions with, and to exercise 
outstanding puts of, any municipal securities dealer which, in the judgment 
of the Investment Manager, ceases at any time to present a minimal credit 
risk. In the event that a dealer should default on its obligation to 
repurchase an underlying security, the Fund is unable to predict whether all 
or any portion of any loss sustained could be subsequently recovered from 
such dealer. During the fiscal year ended December 31, 1997, the Fund did not 
purchase any put options. 
    

   It is the position of the staff of the Securities and Exchange Commission 
that certain provisions of the Act may be deemed to prohibit the Fund from 
purchasing puts from broker-dealers without an exemptive order. Until such an 
order is obtained, the Fund will purchase puts only from commercial banks. 
There is no assurance such an order, if applied for, will be obtained. The 
duration of puts, which will not exceed 60 days, will not be a factor in 
determining the weighted average maturity of the Fund's portfolio securities. 

   In the Revenue Ruling 82-144, the Internal Revenue Service stated that, 
under certain circumstances, a purchaser of tax-exempt obligations which are 
subject to puts will be considered the owner of the obligations for Federal 
income tax purposes. In connection therewith, the Fund has received an 
opinion of counsel to the effect that interest on Municipal Obligations 
subject to puts will be tax-exempt to the Fund. 

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

   In addition to the investment restrictions enumerated in the Prospectus, 
the investment restrictions listed below have been adopted by the Fund as 
fundamental policies, except as otherwise indicated. Under the Act, a 
fundamental policy may not be changed without the vote of the holders of a 
majority of the outstanding voting securities of the Fund, as defined in the 
Act. Such a majority is defined in the Act 

                               15           
<PAGE>
as the lesser of (a) 67% or more of the shares present at a Meeting of 
Shareholders of the Fund, if the holders of more than 50% of the outstanding 
shares of the Fund are present or represented by proxy at the meeting, or (b) 
more than 50% of the outstanding shares of the Fund. For purposes of the 
following restrictions and those recited in the Prospectus: (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 or other changes in total or net assets does not 
require elimination of any security from the portfolio. 

   The Fund may not: 

     1. Invest in common stock. 

     2. Invest in securities of any issuer if, to the knowledge of the Fund, 
    any officer or trustee of the Fund or any officer or director of the 
    Investment Manager owns more than 1/2 of 1% of the outstanding securities 
    of such issuer, and such officers, trustees and directors who own more 
    than 1/2 of 1% own in the aggregate more than 5% of the outstanding 
    securities of such issuer. 

     3. Purchase or sell real estate or interests therein, although it may 
    purchase securities secured by real estate or interests therein. 

     4. Purchase or sell commodities or commodity futures contracts. 

     5. Purchase oil, gas or other mineral leases, rights or royalty 
    contracts, or exploration or development programs. 

     6. Write, purchase or sell puts, calls, or combinations thereof except 
    that it may acquire rights to resell Municipal Obligations at an agreed 
    upon price and at or within an agreed upon time. 

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

     8. Borrow money, except that the Fund may borrow from a bank for 
    temporary or emergency purposes in amounts not exceeding 5% (taken at the 
    lower of cost or current value) of the value of its total assets (not 
    including the amount borrowed). 

     9. Pledge its assets or assign or otherwise encumber them except to 
    secure borrowings effected within the limitations set forth in restriction 
    (8). To meet the requirements of regulations in certain states, the Fund, 
    as a matter of operating policy but not as fundamental policy, will limit 
    any pledge of its assets to 10% of its net assets so long as shares of the 
    Fund are being sold in those states. 

     10. Issue senior securities as defined in the Act except insofar as the 
    Fund may be deemed to have issued a senior security by reason of: (a) 
    entering into any repurchase agreement; (b) purchasing any securities on a 
    when-issued or delayed delivery basis; or (c) borrowing money in 
    accordance with restrictions described above. 

     11. Make loans of money or securities, except: (a) by the purchase of 
    debt obligations in which the Fund may invest consistent with its 
    investment objective and policies; and (b) by investment in repurchase 
    agreements. 

     12. Make short sales of securities. 

     13. Purchase securities on margin, except for such short-term loans as 
    are necessary for the clearance of purchases of portfolio securities. 

     14. Engage in the underwriting of securities, except insofar as the Fund 
    may be deemed an underwriter under the Securities Act of 1933 in disposing 
    of a portfolio security. 

     15. Invest for the purpose of exercising control or management of any 
    other issuer. 

                               16           
<PAGE>
   
   Notwithstanding any other investment policy or restriction, the Fund may 
seek to achieve its investment objectives by investing all or substantially 
all of its assets in another investment company having substantially the same 
investment objectives and policies as the Fund. 
    

PORTFOLIO TRANSACTIONS AND BROKERAGE 
- ----------------------------------------------------------------------------- 

   
   Subject to the general supervision of the Board of Trustees, the 
Investment Manager is responsible for decisions to buy and sell securities 
for the Fund, the selection of brokers and dealers to effect the 
transactions, and the negotiation of brokerage commissions, if any. The Fund 
expects that the primary market for the securities in which it intends to 
invest will generally be the over-the-counter market. Securities are 
generally traded in the over-the-counter market on a "net" basis with dealers 
acting as principal for their own accounts without a stated commission, 
although the price of the security usually includes a profit to the dealer. 
The Fund also expects that securities will be purchased at times in 
underwritten offerings where the price includes a fixed amount of 
compensation, generally referred to as the underwriter's concession or 
discount. On occasion the Fund may also purchase certain money market 
instruments directly from an issuer, in which case no commissions or 
discounts are paid. During the fiscal years ended December 31, 1995, 1996 and 
1997, the Fund paid no brokerage commissions. 

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

   The policy of the Fund, regarding purchases and sale of securities for its 
portfolio, is that primary consideration be given to obtaining the most 
favorable prices and efficient execution of transactions. Consistent with 
this policy, when securities transactions are effected on a stock exchange, 
the Fund's policy is to pay commissions which are considered fair and 
reasonable without necessarily determining that the lowest possible 
commissions are paid in all circumstances. The Fund believes that a 
requirement always to seek the lowest possible commission cost could impede 
effective portfolio management and preclude the Fund and the Investment 
Manager from obtaining a high quality of brokerage and research services. In 
seeking to determine the reasonableness of brokerage commissions paid in any 
transaction, the Investment Manager relies upon its experience and knowledge 
regarding commissions generally charged by various brokers and on its 
judgment in evaluating the brokerage and research services received from the 
broker effecting the transaction. Such determinations are necessarily 
subjective and imprecise, as in most cases an exact dollar value for those 
services is not ascertainable. 

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

                               17           
<PAGE>
   The information and services received by the Investment Manager from 
brokers and dealers may be of benefit to the Investment Manager in the 
management of accounts of some of its other clients and may not in all cases 
benefit the Fund directly. While the receipt of such information and services 
is useful in varying degrees and would generally reduce the amount of 
research or services otherwise performed by the Investment Manager and 
thereby reduce its expenses, it is of indeterminable value and the Fund does 
not reduce the management fee it pays to the Investment Management by any 
amount that may be attributable to the value of such services. 

   
   Pursuant to an order of the Securities and Exchange Commission, the Fund 
may effect principal transactions in certain money market instruments with 
DWR. The Fund will limit its transactions with DWR to U.S. Government and 
Government Agency Securities, Bank Money Instruments (i.e. Certificates of 
Deposit and Bankers' Acceptances) and Commercial Paper (not including 
Tax-Exempt Municipal Paper). Such transactions will be effected with DWR only 
when the price available from DWR is better than that available from other 
dealers. During the fiscal years ended December 31, 1995, 1996 and 1997, the 
Fund did not effect any principal transaction with DWR. 

   Consistent with the policy described above, brokerage transactions in 
securities listed on exchanges or admitted to unlisted trading privileges may 
be effected through DWR, Morgan Stanley & Co. Incorporated and other brokers 
and dealers that are affiliates of the Investment Manager. In order for an 
affiliated broker or dealer to effect portfolio transactions for the Fund, 
the commissions, fees or other remuneration received by the affiliated broker 
or dealer must be reasonable and fair compared to the commission, fees or 
other remuneration paid to other brokers in connection with comparable 
transactions involving similar securities being purchased or sold on an 
exchange during a comparable period of time. This standard would allow the 
affiliated broker or dealer to receive no more than the remuneration which 
would be expected to be received by an unaffiliated broker in a commensurate 
arm's-length transaction. Furthermore, the Trustees of the Fund, including a 
majority of the Trustees who are not "interested" Trustees (as defined in the 
Act), have adopted procedures which are reasonably designed to provide that 
any commissions, fees or other remuneration paid to an affiliated broker or 
dealer are consistent with the foregoing standard. During the fiscal years 
ended December 31, 1995, December 31, 1996 and December 31, 1997, the Fund 
paid no brokerage commissions to an affiliated broker or dealer. 
    

   Subject to the principle of obtaining best price and execution, the 
Investment Manager may consider a broker-dealer's sales of shares of the Fund 
as a factor in selecting from among those broker-dealers qualified to provide 
comparable prices and execution on the Fund's portfolio transactions. The 
Fund does not, however, require a broker-dealer to sell shares of the Fund in 
order for it to be considered to execute portfolio transactions, and will not 
enter into any arrangement whereby a specific amount or percentage of the 
Fund's transactions will be directed to a broker which sells shares of the 
Fund to customers. The Board of Trustees reviews, periodically, the 
allocation of brokerage orders to monitor the operation of these policies. 

   Portfolio turnover rate is defined as the lesser of the value of the 
securities purchased or securities sold, excluding all securities whose 
maturities at time of acquisition were one year or less, divided by the 
average monthly value of such securities owned during the year. Because the 
Fund's portfolio consists of municipal obligations maturing within one year, 
the Fund is unable to predict its turnover rate as so defined. However, 
because of the short-term nature of the Fund's portfolio securities, it is 
anticipated that the number of purchases and sales of maturities of such 
securities will be substantial. Brokerage commissions are not normally 
charged on purchases and sales of short-term municipal obligations, but such 
transactions may involve transaction costs in the form of spreads between bid 
and asked prices. 

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

   
   As discussed in the Prospectus, the Fund offers its shares for sale to the 
public on a continuous basis, without a sales charge. Pursuant to a 
Distribution Agreement between the Fund and Dean Witter Distributors Inc. 
(the "Distributor"), an affiliate of the Investment Manager and a 
wholly-owned subsidiary of MSDWD, shares of the Fund are distributed by the 
Distributor and through certain selected broker-dealers who have entered into 
agreements with the Distributor ("Selected Broker-Dealer") at an 
    

                               18           
<PAGE>
offering price equal to the net asset value per share next determined 
following receipt of an effective purchase order (accompanied by Federal 
Funds). Dealers in the securities markets in which the Fund will invest 
usually require immediate payment in Federal Funds. Since the payment by a 
Fund shareholder for his or her other shares cannot be invested until it is 
converted into and available to the Fund in Federal Funds, the Fund requires 
such payments to be so available before a share purchase order can be 
considered effective. All checks submitted for payment are accepted subject 
to collection at full face value in United States funds and must be drawn in 
United States dollars in a United States bank. 

   
   The Board of Trustees of the Fund, including a majority of the Trustees 
who are not and were not at the time of their vote "Interested persons" (as 
defined in the Act) of either party to the Distribution Agreement (the 
"Independent Trustees"), approved, at its meeting held on April 24, 1997, the 
current Distribution Agreement appointing the Distributor exclusive 
distributor of the Fund's shares and providing for the Distributor to bear 
distribution expenses not borne by the Fund. The current Distribution 
Agreement took effect on May 31, 1997 upon the consummation of the merger of 
Dean Witter, Discover & Co. with Morgan Stanley Group Inc. and is 
substantially identical to a prior Distribution Agreement except for dates of 
effectiveness and termination. By its terms, the Distribution Agreement has 
an initial term ending April 30, 1998, and will remain in effect from year to 
year thereafter if approved by the Board. 
    

SHAREHOLDER INVESTMENT ACCOUNT 

   
   Upon the purchase of shares of the Fund, a Shareholder Investment Account 
is opened for the investor on the books of the Fund, maintained by the Fund's 
Transfer Agent, Dean Witter Trust FSB (the "Transfer Agent"). This is an open 
account in which shares owned by the investor are credited by the Transfer 
Agent in lieu of issuance of a share certificate. If a share certificate is 
desired, it must be requested in writing for each transaction. Certificates 
are issued only for full shares and may be redeposited in the account at any 
time. There is no charge to the investor for issuance of a certificate. 
Whenever a shareholder instituted transaction takes place in the Shareholder 
Investment Account directly through the Transfer Agent, the shareholder will 
be mailed a written confirmation of such transaction. 
    

   Direct Investments Through Transfer Agent. A shareholder may make 
additional investments in Fund shares at any time through the Shareholder 
Investment Account by sending a check payable to Dean Witter Tax-Free Daily 
Income Trust in any amount, not less than $100, directly to the Transfer 
Agent. The shares so purchased will be credited to the Shareholder Investment 
Account. 

   Account Statements. All purchases of Fund shares will be credited to the 
shareholder in a Shareholder Investment Account maintained for the 
shareholder by the Transfer Agent in full and fractional shares of the Fund 
(rounded to the nearest 1/100 of a share with the exception of purchases made 
through reinvestment of dividends). A statement of the account will be mailed 
to the shareholder after each shareholder instituted purchase or redemption 
transaction effected through the Transfer Agent. A quarterly statement of the 
account is sent to all shareholders. Share certificates will not be issued 
unless requested in writing by the shareholder. No certificates will be 
issued for fractional shares or to shareholders who have elected the checking 
account or predesignated bank account methods of withdrawing cash from their 
accounts. 

   
   The Fund and the Distributor reserve the right to reject any order for the 
purchase of shares of the Fund. In addition, the offering of Fund shares may 
be suspended at any time and resumed at any time thereafter. 
    

EXCHANGE PRIVILEGE 

   
   As discussed in the Prospectus under the caption "Exchange Privilege," an 
Exchange Privilege exists whereby investors who have purchased shares of any 
of the Dean Witter Funds that are multiple class funds ("Dean Witter 
Multi-Class Funds"), shares of Dean Witter Multi-State Municipal Series Trust 
and Dean Witter Hawaii Municipal Trust, which are Dean Witter Funds sold with 
a front-end sales charge ("FSC Funds"), and shares of Dean Witter Global 
Short-Term Income Fund Inc. ("Global Short-Term"), 

                               19           
    
<PAGE>
   
which is a Dean Witter Fund offered with a contingent deferred sales charge 
("CDSC"), will be permitted, after the shares of the fund acquired by 
purchase (not by exchange or dividend reinvestment) have been held for 30 
days, to redeem all or part of their shares in that fund, have the proceeds 
invested in shares of the Fund, Dean Witter Liquid Asset Fund Inc., Dean 
Witter U.S. Government Money Market Trust, Dean Witter New York Municipal 
Money Market Trust, or Dean Witter California Tax-Free Daily Income Trust 
(these five funds are hereinafter called "money market funds") or Dean Witter 
Short-Term U.S. Treasury Trust, Dean Witter Limited Term Municipal Trust, 
Dean Witter Short-Term Bond Fund and Dean Witter Intermediate Term U.S. 
Treasury Trust (these nine funds, including the Fund, are hereinafter 
referred to as the "Exchange Funds"). There is no waiting period for 
exchanges of shares acquired by exchange or dividend reinvestment. 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 Global 
Short-Term. 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 
Global Short-Term 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. 
Ultimately, any applicable CDSC will have to be paid upon redemption of 
shares originally purchased from Global Short-Term or a Class of a Dean 
Witter Multi-Class Fund that imposes a CDSC. 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. 
    

   Any new account established through the Exchange Privilege will have the 
same registration and cash dividend or dividend reinvestment plan as the 
present account, unless the Transfer Agent receives written notification to 
the contrary. For telephone exchanges, the exact registration of the existing 
account and the account number must be provided. 

   Any shares held in certificate form cannot be exchanged but must be 
forwarded to the Transfer Agent and deposited into the shareholder's account 
before being eligible for exchange. (Certificates mailed in for deposit 
should not be endorsed.) 

   
   When shares of a Dean Witter Multi-Class Fund or Global Short-Term are 
exchanged for shares of the Fund or any other Exchange Fund, the exchange is 
executed at no charge to the shareholder, without the imposition of the 
contingent CDSC at the time of the exchange. During the period of time the 
shareholder remains in the Exchange Fund (calculated from the last day of the 
month in which the Exchange Fund shares were acquired), the holding period or 
"year since purchase payment made" is frozen. When shares are redeemed out of 
the Exchange Fund, they will be subject to a CDSC which would be based upon 
the period of time the shareholder actually held shares in a Dean Witter 
Multi-Class Fund or Global Short-Term. However, in the case of shares 
exchanged into an Exchange Fund on or after April 23, 1990, upon 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 12b-1 
distribution fees, if any, incurred on or after that date which are 
attributable to those shares. Shareholders acquiring shares of an Exchange 
Fund pursuant to this exchange privilege may exchange those shares back into 
a Dean Witter Multi-Class Fund or Global Short-Term from the Exchange Fund, 
with no CDSC being imposed on such exchange. The holding period previously 
frozen when shares were first exchanged for shares of the Exchange Fund 
resumes on the last day of the month in which shares of a Dean Witter 
Multi-Class Fund or Global Short-Term are reacquired. Thus, a CDSC is imposed 
only upon an ultimate redemption, based upon the time (calculated as 
described above) the shareholder was invested in a Dean Witter Multi-Class 
Fund or Global Short-Term. In the case of exchanges of Class A shares of a 
Dean Witter Multi-Class Fund that are subject to a CDSC, the holding period 
also includes the time (calculated as described above) the shareholder was 
invested in a FSC Fund. 
    

                               20           
<PAGE>
   
   When shares initially purchased in a Dean Witter Multi-Class Fund or 
Global Short-Term are exchanged for shares of a Dean Witter Multi-Class Fund, 
shares of Global Short-Term, shares of an FSC Fund or shares of an Exchange 
Fund, the date of purchase of the shares of the fund exchanged into, for 
purposes of the CDSC upon redemption, will be the last day of the month in 
which the shares being exchanged were originally purchased. In allocating the 
purchase payments between funds for purposes of the CDSC, the amount which 
represents the current net asset value of shares at the time of the exchange 
which were (i) purchased more than one, three or six years (depending on the 
CDSC schedule applicable to the shares) prior to the exchange, (ii) 
originally acquired through reinvestment of dividends or distributions and 
(iii) acquired in exchange for shares of FSC Funds, or for shares of other 
Dean Witter Funds for which shares of FSC Funds have been exchanged (all such 
shares called "Free Shares"), will be exchanged first. After an exchange, all 
dividends earned on shares in the Exchange Fund will be considered Free 
Shares. If the exchanged amount exceeds the value of such Free Shares, an 
exchange is made, on a block-by-block basis, of non-Free Shares held for the 
longest period of time (except that if shares held for identical periods of 
time but subject to different CDSC schedules are held in the same Exchange 
Privilege account, the shares of that block that are subject to a lower CDSC 
rate will be exchanged prior to the shares of that block that are subject to 
a higher CDSC rate). Shares equal to any appreciation in the value of 
non-Free Shares exchanged will be treated as Free Shares, and the amount of 
the purchase payments for the non-Free Shares of the fund exchanged into will 
be equal to the lesser of (a) the purchase payments for, or (b) the current 
net asset value of, the exchanged non-Free Shares. If an exchange between 
funds would result in exchange of only part of a particular block of non-Free 
Shares, then shares equal to any appreciation in the value of the block (up 
to the amount of the exchange) will be treated as Free Shares and exchanged 
first, and the purchase payment for that block will be allocated on a pro 
rata basis between the non-Free Shares of that block to be retained and the 
non-Free Shares to be exchanged. The prorated amount of such purchase payment 
attributable to the retained non-Free Shares will remain as the purchase 
payment for such shares, and the amount of purchase payment for the exchanged 
non-Free Shares will be equal to the lesser of (a) the prorated amount of the 
purchase payment for, or (b) the current net asset value of, those exchanged 
non-Free Shares. Based upon the exchange procedures described in the Dean 
Witter Multi-Class Fund Prospectus under the caption "Purchase of Fund 
Shares" and in the Global Short-Term Prospectus under the caption "Contingent 
Deferred Sales Charge," any applicable CDSC will be imposed upon the ultimate 
redemption of shares of any fund, regardless of the number of exchanges since 
those shares were originally purchased. 
    

   With respect to the redemption or repurchase of shares of the Fund, the 
application of proceeds to the purchase of new shares in the Fund or any 
other of the funds and the general administration of the Exchange Privilege, 
the Transfer Agent acts as agent for DWR and for the shareholder's Selected 
Broker-Dealer, if any, in the performance of such functions. With respect to 
exchanges, redemptions or repurchases, the Transfer Agent shall be liable for 
its own negligence and not for the default or negligence of its 
correspondents or for losses in transit. The Fund shall not be liable for any 
default or negligence of the Transfer Agent, Distributor, or any Selected 
Broker-Dealer. 

   Exchange Privilege accounts may also be maintained for shareholders of the 
money market funds who acquired their shares in exchange for shares of 
various TCW/DW Funds, a group of funds distributed by the Distributor for 
which TCW Funds Management, Inc. serves as Adviser, under the terms and 
conditions described in the Prospectus and Statement of Additional 
Information of each TCW/DW Fund. 

   The Distributor and any Selected Broker-Dealer have authorized and 
appointed the Transfer Agent to act as their agent in connection with the 
application of proceeds of any redemption of Fund shares to the purchase of 
the shares of any other fund and the general administration of the Exchange 
Privilege. No commission or discounts will be paid to DWR or any Selected 
Broker-Dealer for any transactions pursuant to this Exchange Privilege. 

   
   Shares of the Fund acquired pursuant to the Exchange Privilege will be 
held by the Fund's transfer agent in an Exchange Privilege account distinct 
from any account of the same shareholder who may have acquired shares of the 
Fund directly. A shareholder of the Fund will not be permitted to make 
    

                               21           
<PAGE>
   
additional investments in such Exchange Privilege account except through the 
exchange of additional shares of the fund in which the shareholder had 
initially invested, and the proceeds of any shares redeemed from such 
Exchange Privilege account may not thereafter be placed back into that 
Exchange Privilege account, except by utilizing the Reinstatement Privilege 
(see "Redemptions and Repurchases--Reinstatement Privilege" in the Dean 
Witter Multi-Class Fund, Global Short-Term Fund or FSC Fund Prospectus). If 
such a shareholder desires to make any additional investments in the Fund, a 
separate account will be maintained for receipt of such investments. The Fund 
will have additional costs for account maintenance if a shareholder has more 
than one account with the Fund. 
    

   The Fund also maintains Exchange Privilege Accounts for shareholders who 
acquired their shares of the Fund pursuant to exchange privileges offered by 
other investment companies with which the Investment Manager is not 
affiliated. The Fund also expects to make available such exchange privilege 
accounts to other investment companies that may hereafter be managed by the 
Investment Manager. 

   
   Exchanges are subject to the minimum investment requirement and any other 
conditions imposed by each fund. (The minimum initial investment for the 
Exchange Privilege Account of each Class is $10,000 for Dean Witter 
Short-Term U.S. Treasury Trust (although that fund may, in its discretion, 
accept initial purchases of as low as $5,000) and $5,000 for the Fund, Dean 
Witter Liquid Asset Fund Inc., Dean Witter California Tax-Free Daily Income 
Trust and Dean Witter New York Municipal Money Market Trust, although those 
funds may, at their discretion, accept initial investments of as low as 
$1,000. The minimum initial investment for the Exchange Privilege account of 
each Class is $5,000 for Dean Witter Special Value Fund. The minimum initial 
investment for the Exchange Privilege account of each Class of all other Dean 
Witter Funds for which the Exchange Privilege is available is $1,000.) Upon 
exchange into an Exchange Fund, the shares of that fund will be held in a 
special Exchange Privilege Account separately from accounts of those 
shareholders who have acquired their shares directly from that fund. As a 
result, certain services normally available to shareholders of money market 
funds, including the check writing feature, will not be available for funds 
held in that account. 

   The Fund and each of the other Dean Witter Funds may limit the number of 
times this Exchange Privilege may be exercised by any investor within a 
specified period of time. Also, the Exchange Privilege may be terminated or 
revised at any time by any of the Dean Witter Funds, 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 Exchange Funds or TCW/DW North American Government Income 
Trust, including personal services to shareholders and maintenance of 
shareholder accounts, pursuant to this Exchange Privilege, and provided 
further that the Exchange Privilege may be terminated or materially revised 
at times (a) when the New York Stock Exchange is closed for other than 
customary weekends and holidays, (b) when trading on the Exchange is 
restricted, (c) when an emergency exists as a result of which disposal by the 
Fund of securities owned by it is not reasonably practicable or it is not 
reasonably practicable for the Fund fairly to determine the value of its net 
assets, (d) during any other period when the Securities and Exchange 
Commission by order so permits (provided that applicable rules and 
regulations of the Securities and Exchange Commission shall govern as to 
whether the conditions prescribed in (b) or (c) exist), or (e) if the Fund 
would be unable to invest amounts effectively in accordance with its 
investment objective(s), policies and restrictions. 
    

   The current prospectus for each fund describes its investment objective(s) 
and policies, and shareholders should obtain a copy and examine it carefully 
before investing. 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. 
For further information regarding the Exchange Privilege, shareholders should 
contact their DWR or other Selected Broker-Dealer account executive or the 
Transfer Agent. 

PLAN OF DISTRIBUTION 

   
   As discussed in the Prospectus, the Fund has entered into a Plan of 
Distribution pursuant to Rule 12b-1 under the Act with the Distributor 
whereby the expenses of certain activities in connection with the 
    
                                 22           
<PAGE>
   
distribution of shares of the Fund are reimbursed. The Plan was initially 
approved by the Board of Trustees on April 15, 1987 and by the Fund's 
shareholders on April 20, 1987. The Plan is substantially identical to the 
agreement of distribution adopted by the Fund in 1983 and which was in effect 
until the reorganization of the Fund in 1987 as a Massachusetts business 
trust. The vote of the Trustees included a majority of the Trustees who are 
not and were not at the time of their voting interested persons of the Fund 
and who have and had at the time of their votes no direct or indirect 
financial interest in the operation of the Plan (the "Independent Trustees"), 
cast in person at a meeting called for the purpose of voting on such Plan. 

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

   The Fund is authorized to reimburse specific expenses incurred or to be 
incurred in promoting the distribution of the Fund's shares. Reimbursement is 
made through monthly payments in amounts determined in advance of each 
calendar quarter by the Trustees, including a majority of the Independent 
Trustees. The amount of each monthly payment may in no event exceed an amount 
equal to a payment at the annual rate of 0.15 of 1% of the Fund's average 
daily net assets during the month. No interest or other financing charges, if 
any, incurred on any distribution expense incurred pursuant to the Plan will 
be reimbursable under the Plan. In the case of all expenses other than 
expenses representing a residual to account executives, such amounts shall be 
determined at the beginning of each calendar quarter by the Trustees, 
including a majority of the Independent 12b-1 Trustees. Expenses representing 
a residual to account executives may be reimbursed without prior 
determination. In the event that the Distributor proposes that monies shall 
be reimbursed for other than such expenses, then in making quarterly 
determinations of the amounts that may be expended by the Fund, the 
Distributor will provide and the Trustees will review a quarterly budget of 
projected incremental distribution expenses to be incurred on behalf of the 
Fund, together with a report explaining the purposes and anticipated benefits 
of incurring such expenses. The Trustees will determine which particular 
expenses, and the portions thereof, that may be borne by the Fund, and in 
making such a determination shall consider the scope of the Distributor's 
commitment to promoting the distribution of the Fund's shares. 

   The Distributor has informed the Fund that the entire amount of the fees 
payable by the Fund each year pursuant to the Plan is characterized as a 
"service fee" under the Rules of the Association of the National Association 
of Securities Dealers (of which the Distributor is a member). Such fee is a 
payment made for personal service and/or maintenance of shareholder accounts. 

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

   The Fund accrued $534,396 to the Distributor, pursuant to the Plan of 
Distribution, for its fiscal year ended December 31, 1997. The amount accrued 
is equivalent to an annual rate of 0.10 of 1% of the Fund's average daily net 
assets for its fiscal year ended December 31, 1997. Based upon the total 
    

                               23           
<PAGE>
   
amounts spent by the Distributor during the period, it is estimated that the 
amount paid by the Fund to the Distributor for distribution was spent in 
approximately the following ways: (i) advertising--$-0-; (ii) printing and 
mailing prospectuses to other than current shareholders--$-0-; (iii) 
compensation to underwriters--$-0-; (iv) compensation to dealers--$-0-; (v) 
compensation to sales personnel--$-0-; and (vi) other, which accrued for 
expenses relating to compensation of sales personnel and other miscellaneous 
expenses--$534,396. No payments under the Plan were made for overhead, 
interest, carrying or other financing charges. 
    

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

   The Plan will continue in effect from year to year, provided such 
continuance is approved annually by a vote of the Trustees, including a 
majority of the Independent Trustees. An amendment to increase materially the 
maximum amount authorized to be spent under the Plan must be approved by the 
shareholders of the Fund, and all material amendments to the Plan must be 
approved by the Trustees in the manner described above. The Plan may be 
terminated at any time, without payment of any penalty, by vote of the 
holders of a majority of the Independent Trustees or by a vote of a majority 
of the outstanding voting securities of the Fund (as defined in the Act) on 
not more than 30 days written notice to any other party to the Plan. So long 
as the Plan is in effect, the selection or nomination of the Independent 
12b-1 Trustees is committed to the discretion of the 12b-1 Trustees. 

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

   At their meeting held on October 30, 1992, the Trustees of the Fund, 
including all of the Independent 12b-1 Trustees, approved certain amendments 
to the Plan which took effect in January, 1993 and were designed to reflect 
the fact that upon the reorganization described above, the share distribution 
activities, theretofore performed by the Fund or for the Fund by DWR were 
assumed by the Distributor and DWR's, sales activities are now being 
performed pursuant to the terms of a selected dealer agreement between the 
Distributor and DWR. The amendments provide that payments under the Plan will 
be made to the Distributor rather than to the Investment Manager as before 
the amendment, and that the Distributor in turn is authorized to make 
payments to DWR, its affiliates or other Selected Broker-Dealers (or direct 
that the Fund pay such entities directly). The Distributor is also authorized 
to retain part of such fee as compensation for its own distribution-related 
expenses. 

   
   At their meeting held on April 24, 1997, the Board of Trustees approved 
the continuance of the Plan until April 30, 1998. In making their 
determination to continue the Plan until April 30, 1998, the Board of 
Trustees, including all of the Independent Trustees, arrived at the 
conclusion that the Plan had benefited the Fund. This conclusion was based 
upon the Investment Manager's belief that the expenditures made pursuant to 
the Plan had tended to arrest the decline of Fund assets by meeting the 
competitive efforts of other, similar financial products, and had encouraged 
the account executives employed by DWR and other Selected Broker-Dealers to 
increase their efforts in selling shares of the Fund. The Board of Trustees, 
including the Independent Trustees, also concluded that, in their judgment, 
there is a reasonable likelihood that the Plan will continue to benefit the 
Fund and its shareholders. 

   No interested person of the Fund nor any Trustee of the Fund who is not an 
interested person of the Fund, as defined in the Act, had any direct or 
indirect financial interest in the operation of the Plan and Agreement except 
to the extent that the Distributor, InterCapital, DWR, DWSC or the Investment 
Manager or certain of its employees may be deemed to have such an interest as 
a result of benefits derived from the successful operation of the Plan or as 
a result of receiving a portion of the amounts expended thereunder by the 
Fund.

HOW NET ASSET VALUE IS DETERMINED 
- ----------------------------------------------------------------------------- 

   
   As discussed in the Prospectus, the net asset value of the Fund is 
determined as of the close of trading on each day that the New York Stock 
Exchange is open. The New York Stock Exchange currently observes the 
following holidays: New Year's Day, Reverend Dr. Martin Luther King, Jr. Day, 
Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor Day, 
Thanksgiving Day and Christmas Day. 
    

   The Fund utilizes the amortized cost method in valuing its portfolio 
securities for purposes of determining the net asset value of shares of the 
Fund. The Fund utilizes the amortized cost method in valuing its portfolio 
securities even though the portfolio securities may increase or decrease in 
market value, generally, in connection with changes in interest rates. The 
amortized cost method of valuation involves valuing a security at its cost 
adjusted by a constant amortization to maturity of any discount or premium, 
regardless of the impact of fluctuating interest rates on the market value of 
the instrument. While this method provides certainty in valuation, it may 
result in periods during which value, as determined by amortized cost, is 
higher or lower than the price the Fund would receive if it sold the 
instrument. During such periods, the yield to investors in the Fund may 
differ somewhat from that obtained in a similar company which uses mark to 
market values for all its portfolio securities. For example, if the use of 
amortized cost resulted in a lower (higher) aggregate portfolio value on a 
particular day, a prospective investor in the Fund would be able to obtain a 
somewhat higher (lower) yield than would result from investment in such a 
similar company and existing investors would receive less (more) investment 
income. The purpose of this method of calculation is to facilitate the 
maintenance of a constant net asset value per share of $1.00. 

   
   The Fund's use of the amortized cost method to value its portfolio 
securities and the maintenance of the per share net asset value of $1.00 is 
permitted pursuant to Rule 2a-7 of the Act (the "Rule") and pursuant to an 
order of exemption granted to the Fund by the Securities and Exchange 
Commission, dated February 18, 1981 (the "Order"), and is conditioned on its 
compliance with various conditions contained in the Rule including: (a) the 
Fund's Board of Trustees is obligated, as a particular responsibility within 
the overall duty of care owed to the Fund's shareholders, to establish 
procedures reasonably designed, taking into account current market conditions 
and the Fund's investment objective, to stabilize the net asset value per 
share as computed for the purpose of distribution and redemption at $1.00 per 
share; (b) (i) the procedures include calculation, at such intervals as are 
reasonable in light of current market conditions, of the deviation, if any 
between net asset value per share using amortized cost to value portfolio 
securities and net asset value per share based upon available market 
quotations with respect to such portfolio securities (for the purpose of 
determining market value, securities as to which the Fund has a "put" will be 
valued at the higher of market value or exercise price); (ii) periodic review 
by the Trustees of the amount of deviation as well as methods used to 
calculate it, and (iii) maintenance of written records of the procedures, the 
Trustees considerations made pursuant to them and any actions taken upon such 
consideration; the Trustees will consider what steps should be taken, if any, 
in the event of a difference of more than 0.50 of 1% between the two methods 
of valuation; and (c) the Trustees should take such action as they deem 
appropriate to eliminate or reduce, to the extent reasonably practicable, 
material dilution or other unfair results to investors or existing 
shareholders. Such action may include: selling portfolio instruments prior to 
maturity to realize capital gains or losses or to shorten the average 
portfolio maturity of the Fund; withholding dividends; utilizing a net asset 
value per share as determined by using available market quotations or 
reducing the number of its outstanding shares. Any reduction of outstanding 
shares will be effected by having each shareholder proportionately contribute 
to the Fund's capital a number of shares which represent the difference 
between the amortized cost valuation and market valuation of the portfolio. 
Each shareholder will be deemed to have agreed to such contribution by his or 
her investment in the Fund. 
    

   The Rule further requires that the Fund limit its investments to U.S. 
dollar-denominated instruments which the Board of Trustees determines present 
minimal credit risks and which are Eligible Securities as defined below. The 
Rule also requires the Fund to maintain a dollar weighted average portfolio 
maturity (not more than 90 days) appropriate to the objective of maintaining 
a stable net asset value of $1.00 per share and precludes the purchase of any 
instrument with a remaining maturity of more than thirteen 

                               25           
<PAGE>
months. Should the disposition of a portfolio security result in a dollar 
weighted average portfolio maturity of more than 90 days, the Fund would be 
required to invest its available cash in such a manner as to reduce such 
maturity to 90 days or less as soon as is reasonably practicable. 

   At the time the Fund makes the commitment to purchase a Municipal 
Obligation on a when-issued or delayed delivery basis, it will record the 
transaction and thereafter reflect the value, each day, of the Municipal 
Obligation in determining its net asset value. Repurchase agreements are 
valued at the face value of the repurchase agreement plus any accrued 
interest thereon to date. 

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

   A variable rate obligation that is subject to a demand feature is deemed 
to have a maturity equal to the longer of the period remaining until the next 
readjustment of the interest rate or the period remaining until the principal 
amount can be recovered through demand. A floating rate instrument that is 
subject to a demand feature is deemed to have a maturity equal to the period 
remaining until the principal amount can be recovered through demand. 

   
   An Eligible Security generally is defined in the Rule to mean (i) a 
security with a remaining maturity of 397 calendar days or less that has 
received a short-term rating (or that has been issued by an issuer that has 
received a short-term rating with respect to a class of debt obligations, or 
any debt obligation within that class, that is comparable in priority and 
security with the security) by the Requisite NRSROs in one of the two highest 
short-term rating categories (within which there may be sub-categories or 
gradations indicating relative standing); or (ii) a security: (a) that at the 
time of issuance had a remaining maturity of more than 397 calendar days but 
that has a remaining maturity of 397 calendar days or less; and (b) whose 
issuer has received from the Requisite NRSROs a rating with respect to a 
class of debt obligations (or any debt obligation within that class) that is 
now comparable in priority and security with the security, in one of the two 
highest short-term rating categories (within which there may be 
sub-categories or gradations indicating relative standing); or (iii) an 
Unrated Security that is of comparable quality to a security meeting the 
requirements of (i) or (ii) above, as determined by the money market fund's 
board of directors. 
    

   As permitted by the Rule, the Board has delegated to the Fund's Investment 
Manager, subject to the Board's oversight pursuant to guidelines and 
procedures adopted by the Board, the authority to determine which securities 
present minimal credit risks and which unrated securities are comparable in 
quality to rated securities. 

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

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

                               26           
<PAGE>
   
   If the Board determines that it is no longer in the best interests of the 
Fund and its shareholders to maintain a stable price of $1 per share or if 
the Board believes that maintaining such price no longer reflects a 
market-based net asset value per share, the Board has the right to change 
from an amortized cost basis of valuation to valuation based on market 
quotations. The Trust will notify shareholders of any such changes. 
    

   In determining the "maturity" of variable rate Municipal Obligations, the 
Board of Trustees of the Fund has adopted procedures under which the longer 
of (i) the date upon which the Fund may obtain prepayment of the principal 
amount of an obligation (provided demand for prepayment may be made on not 
more than seven days' notice) or (ii) the date upon which the interest rate 
of a variable rate obligation is required to be next adjusted, may in certain 
circumstances be considered as the maturity date of the obligation. In 
addition, the presence of a line of credit or other credit facility offered 
by a bank or other financial institution which guarantees the payment 
obligation of the issuer of a Municipal Obligation may be taken into account 
by the Board of Trustees in determining whether an investment is of "high 
quality." 

   The Fund will manage its portfolio in an effort to maintain a constant 
$1.00 per share price, but it cannot assure that the value of its shares will 
never deviate from this price. Since dividends from net investment income are 
declared and reinvested on a daily basis, the net asset value per share, 
under ordinary circumstances, is likely to remain constant. Realized and 
unrealized gains and losses will not be distributed on a daily basis but will 
be reflected in the Fund's net asset value. The amounts of such gains and 
losses will be considered by the Board of Trustees in determining the action 
to be taken to maintain the Fund's $1.00 per share net asset value. Such 
action may include distribution at any time of part or all of the then 
accumulated undistributed net realized capital gains, or reduction or 
elimination of daily dividends by an amount equal to part or all of the then 
accumulated net realized capital losses. However, if realized losses should 
exceed the sum of net investment income plus realized gains on any day, the 
net asset value per share on that day might decline below $1.00 per share. In 
such circumstances, the Fund may reduce or eliminate the payment of daily 
dividends for a period of time in an effort to restore the Fund's $1.00 per 
share net asset value. A decline in prices of securities could result in 
significant unrealized depreciation on a mark to market basis. Under these 
circumstances the Fund may reduce or eliminate the payment of dividends and 
utilize a net asset value per share as determined by using available market 
quotations or reduce the number of its shares outstanding. 

REDEMPTION OF FUND SHARES 
- ----------------------------------------------------------------------------- 

   As discussed in the Prospectus, shares of the Fund may be redeemed at net 
asset value at any time. When a redemption is made by check and a check is 
presented to the Transfer Agent for payment, the Transfer Agent will redeem a 
sufficient number of full and fractional shares in the shareholder's account 
to cover the amount of the check. This enables the shareholder to continue 
earning daily income dividends until the check has cleared. 

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

   The Fund reserves the right to suspend redemptions or postpone the date of 
payment (1) for any periods during which the New York Stock Exchange is 
closed (other than for customary weekend and holiday closings), (2) when 
trading on that Exchange is restricted or an emergency exists, as determined 
by the Securities and Exchange Commission, so that disposal of the Fund's 
investments or determination of the Fund's net asset value is not reasonably 
practicable, or (3) for such other periods as the Commission by order may 
permit for the protection of the Fund's investors. 

   As discussed in the Prospectus, due to the relatively high cost of 
handling small investments, the Fund reserves the right to redeem, at net 
asset value, the shares of any shareholder (other than shares 

                               27           
<PAGE>
held in an Individual Retirement Account or custodial account under Section 
403(b)(7) of the Internal Revenue Code) whose shares due to redemptions by 
the shareholders have a value of less than $1,000 or such lesser amounts as 
may be fixed by the Board of Trustees. However, before the Fund redeems such 
shares and sends the proceeds to the shareholder, it will notify the 
shareholder that the value of his or her shares is less than $1,000 and allow 
him or her sixty days to make an additional investment in an amount which 
will increase the value of his or her account to $1,000 or more before the 
redemption is processed. 

   
   It has been and remains the Fund's policy and practice that, if checks for 
redemption proceeds remain uncashed, no interest will accrue on amounts 
represented by such uncashed checks. 
    

   Systematic Withdrawal Plan. As discussed in the Prospectus, a systematic 
withdrawal plan is available for shareholders who own or purchase shares of 
the Fund having a minimum value of at least $5,000, which provides for 
monthly or quarterly checks in any dollar amount not less than $25, or in any 
whole percentage of the account balance, on an annualized basis. The Transfer 
Agent acts as agent for the shareholder in tendering to the Fund for 
redemption sufficient full and fractional shares to provide the amount of the 
periodic withdrawal payment designated in the application. 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 business day) of the relevant month or 
quarter and normally a check for the proceeds will be mailed by the Transfer 
Agent within five days after the date of redemption. The withdrawal plan may 
be terminated at any time by the Fund. 

   Any shareholder who wishes to have payments under the withdrawal plan made 
to a third party, or sent to an address other than the one listed on the 
account, must send complete written instructions to the Transfer Agent to 
enroll in the withdrawal plan. The shareholder's signature on such 
instructions 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 shareholder may, at any time, change the amount and interval of 
withdrawal payments through his or her Account Executive or by written 
notification to the Transfer Agent. In addition, the party and/or the address 
to which checks are mailed may be changed by written notification to the 
Transfer Agent, with signature guarantees required in the manner described 
above. The shareholder may also terminate the withdrawal plan at any time by 
written notice to the Transfer Agent. In the event of such termination, the 
account will be continued as a regular shareholder investment account. The 
shareholder may also redeem all or part of the shares held in the withdrawal 
plan account (see "Redemption of Fund Shares" in the Prospectus) at any time. 
If the number of shares redeemed is greater than the number of shares paid as 
dividends, such redemptions may, of course, eventually result in liquidation 
of all the shares in the account. The automatic cash withdrawal method of 
redemption is not available for shares held in an Exchange Privilege Account. 

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

   As discussed in the Prospectus, the Fund intends to declare dividends, 
payable on each day the New York Stock Exchange is open for business and 
distribute all of its daily net investment income to shareholders of record 
as of the close of business the preceding business day. 

   In computing net investment income, the Fund will amortize any premiums 
and original issue discount on securities owned, if applicable. Capital gains 
or losses realized upon sale or maturity of such securities will be based on 
their amortized cost. 

   
   Gains or losses on the sales of securities by the Fund will be long-term 
capital gains or losses if the securities have been held by the Fund for more 
than twelve months. Gains or losses on the sale of securities held for twelve 
months or less will be short-term capital gains or losses. Treasury intends 
to issue regulations to permit shareholders to take into account their 
proportionate share of the Fund's capital gains distributions that will be 
subject to a reduced rate under the Taxpayer Relief Act of 1997. The Taxpayer 
Relief Act reduced the maximum tax on long-term capital gains from 28% to 
20%; however, it also lengthened the required holding period to obtain this 
lower rate from more than 12 months to more 
    
                               28           

<PAGE>
   
than 18 months. These lower rates do not apply to collectibles and certain 
other assets. Additionally, the maximum capital gain rate for assets that are 
held more than 5 years and that are acquired after December 31, 2000 is 18%. 

   At December 31, 1997, the Fund had a net capital loss carryover of 
approximately $2,500 which will be available through December 31, 2002, to 
offset future capital gains to the extent provided by regulations. 
    

   The Fund has qualified and intends to remain qualified as a regulated 
investment company under Subchapter M of the Internal Revenue Code of 1986 
(the "Code"). If so qualified, the Fund will not be subject to federal income 
tax on its net investment income and capital gains, if any, realized during 
any fiscal year to the extent that it distributes such income and capital 
gains to its shareholders. 

   As discussed in the Prospectus, the Fund intends to qualify to pay 
"exempt-interest 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 
assets in tax-exempt securities. An exempt-interest dividend is that part of 
a dividend distribution made by the Fund which consists of interest received 
by the Fund on tax-exempt securities upon which the shareholder incurs no 
federal income taxes. 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. 

   
   Within 60 days after the end of its fiscal year, the Fund will mail to 
shareholders a statement indicating the percentage of the dividend 
distributions for such fiscal year which constitutes exempt-interest 
dividends and the percentage, if any, that is taxable, and to what extent the 
taxable portion is long-term capital gains, short-term capital gains or 
ordinary income. This percentage should be applied uniformly to all monthly 
distributions made during the fiscal year to determine what proportion of the 
dividends paid is tax-exempt. The percentage may differ from the percentage 
of tax-exempt dividend distributions for any particular month. 

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

   Any loss on the sale or exchange of shares of the Fund which are held for 
6 months or less is disallowed to the extent of the amount of any 
exempt-interest dividend paid with respect to such shares. Treasury 
Regulations may provide for a reduction in such required holding periods. If 
a shareholder receives a dividend that is taxed as a long-term capital gain 
on shares held for six months or less and sells those shares at a loss, the 
loss will be treated as a long-term capital loss. 

   Interest on indebtedness incurred or continued by a shareholder to 
purchase or carry shares of the Fund is not deductible. Furthermore, entities 
or persons who are "substantial users" (or related persons) of facilities 
financed by industrial development bonds should consult their tax advisers 
before purchasing shares of the Fund. "Substantial user" is defined generally 
by Income Tax Regulation 1.103-11(b) as including a "non-exempt person" who 
regularly uses in trade or business a part of a facility financed from the 
proceeds of industrial development bonds. 

   From time to time, proposals have been introduced before Congress for the 
purpose of restricting or eliminating the federal income tax exemption for 
interest on municipal securities. Similar proposals may be introduced in the 
future. If such a proposal were enacted, the availability of municipal 
securities 

                               29           
<PAGE>
for investment by the Fund could be affected. In that event, the Fund would 
re-evaluate its investment objective and policies. 

   The exemption of interest income for federal income tax purposes does not 
necessarily result in exemption under the income or other tax laws of any 
state or local taxing authority. Thus, shareholders of the Fund may be 
subject to state and local taxes on exempt-interest dividends. Shareholders 
should consult their tax advisers about the status of dividends from the Fund 
in their own states and localities. The Fund will report annually to 
shareholders the percentage of interest income earned by the Fund during the 
preceding year on tax-exempt obligations, indicating, on a state-by-state 
basis, the source of such income. 

   Any dividends or capital gains distributions received by a shareholder 
from any investment company will have the effect of reducing the net asset 
value of the shareholder's stock in that fund by the exact amount of the 
dividend or capital gains distribution. Furthermore, capital gains 
distributions are, and some portion of the dividends may be, subject to 
income tax. If the net asset value of the shares should be reduced below a 
shareholder's cost as a result of the payment of taxable dividends or the 
distribution of realized net long-term capital gains, such payment or 
distribution would be in part a return of capital but nonetheless would be 
taxable to the shareholder. Therefore, an investor should consider the tax 
implications of purchasing Fund shares immediately prior to a distribution 
record date. 

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

INFORMATION ON COMPUTATION OF YIELD 

   
   The Fund's current yield for the seven days ending December 31, 1997 was 
3.21%. The effective annual yield on December 31, 1997 was 3.26%, assuming 
daily compounding. 
    

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

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

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

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

   
   Based upon a Federal personal income tax bracket of 39.6% (the highest 
current individual marginal tax rate), the Fund's tax-equivalent yield for 
the seven days ending December 31, 1997 was 5.31%. 
    

                               30           
<PAGE>
   Tax-equivalent yield is computed by dividing that portion of the current 
yield (calculated as described above) which is tax-exempt by 1 minus a stated 
tax rate and adding the quotient to that portion, if any, of the yield of the 
Fund that is not tax-exempt. 

   
   The Fund may also advertise the growth of hypothetical investments of 
$10,000, $50,000 and $100,000 in shares of the Fund by adding the sum of all 
distributions on 10,000, 50,000 or 100,000 shares of the Fund since inception 
to $10,000, $50,000 and $100,000, as the case may be. Investments of $10,000, 
$50,000 and $100,000 in the Fund at inception would have grown to $20,448, 
$102,240 and $204,480, respectively, at December 31, 1997.

RATING OF INVESTMENTS 
- ----------------------------------------------------------------------------- 

MOODY'S INVESTORS SERVICE INC. ("MOODY'S") 

                            MUNICIPAL BOND RATINGS 

<TABLE>
<CAPTION>
<S>      <C>
 Aaa     Bonds which are rated Aaa are judged to be of the best quality. They carry the smallest degree of investment 
         risk and are generally referred to as "gilt edge." Interest payments are protected by a large or by an 
         exceptionally stable margin and principal is secure. While the various protective elements are likely to 
         change, such changes as can be visualized are most unlikely to impair the fundamentally strong position 
         of such issues. 
Aa       Bonds which are Aa are judged to be of high quality by all standards. Together with the Aaa group they 
         comprise what are generally known as high grade bonds. They are rated lower than the best bonds because 
         margins of protection may not be as large as in Aaa securities or fluctuation of protective elements may 
         be of greater amplitude or there may be other elements present which make the long-term risks appear somewhat 
         larger than in Aaa securities. 
A        Bonds which are rated A possess many favorable investment attributes and are to be considered as upper 
         medium grade obligations. Factors giving security to principal and interest are considered adequate, but 
         elements may be present which suggest a susceptibility to impairment sometime in the future. 
Baa      Bonds which are rated Baa are considered as medium grade obligations; i.e., they are neither highly protected 
         nor poorly secured. Interest payments and principal security appear adequate for the present but certain 
         protective elements may be lacking or may be characteristically unreliable over any great length of time. 
         Such bonds lack outstanding investment characteristics and in fact have speculative characteristics as 
         well. 
         Bonds rated Aaa, Aa, A and Baa are considered investment grade bonds. 
Ba       Bonds which are rated Ba are judged to have speculative elements; their future cannot be considered as 
         well assured. Often the protection of interest and principal payments may be very moderate, and therefore 
         not well safeguarded during both good and bad times in the future. Uncertainty of position characterizes 
         bonds in this class. 
B        Bonds which are rated B generally lack characteristics of the desirable investment. Assurance of interest 
         and principal payments or of maintenance of other terms of the contract over any long period of time may 
         be small. 
Caa      Bonds which are rated Caa are of poor standing. Such issues may be in default or there may be present elements 
         of danger with respect to principal or interest. 
Ca       Bonds which are rated Ca present obligations which are speculative in a high degree. Such issues are often 
         in default or have other marked shortcomings. 
C        Bonds which are rated C are the lowest rated class of bonds, and issues so rated can be regarded as having 
         extremely poor prospects of ever attaining any real investment standing. 
</TABLE>

   Conditional Rating: Bonds for which the security depends upon the 
completion of some act or the fulfillment of some condition are rated 
conditionally. These bonds secured by (a) earnings of projects under 
construction, (b) earnings of projects unseasoned in operation experience, 
(c) rentals which begin when facilities are completed or (d) payments to 
which some other limiting condition attaches. Parenthetical rating denotes 
probable credit stature upon completion of construction or elimination of 
basis of condition. 

   Rating Refinements: Moody's may apply numerical modifiers, 1, 2, and 3 in 
each generic rating classification from Aa through B in its municipal bond 
rating system. The modifier 1 indicates that the security ranks in the higher 
end of its generic rating category; the modifier 2 indicates a mid-range 
ranking; and a modifier 3 indicates that the issue ranks in the lower end of 
its generic rating category.

<PAGE>
                            MUNICIPAL NOTE RATINGS 

   Moody's ratings for state and municipal note and other short-term loans 
are designated Moody's Investment Grade (MIG). MIG 1 denotes best quality and 
means there is present strong protection from established cash flows, 
superior liquidity support or demonstrated broad-based access to the market 
for refinancing. MIG 2 denotes high quality and means that margins of 
protection are ample although not as large as in MIG 1. MIG 3 denotes 
favorable quality and means that all security elements are accounted for but 
that the undeniable strength of the previous grades, MIG 1 and MIG 2, is 
lacking. MIG 4 denotes adequate quality and means that the protection 
commonly regarded as required of an investment security is present and that 
while the notes are not distinctly or predominantly speculative, there is 
specific risk. 

                       VARIABLE RATE DEMAND OBLIGATIONS 

   A short-term rating, in addition to the Bond or MIG ratings, designated 
VMIG may also be assigned to an issue having a demand feature. The assignment 
of the VMIG symbol reflects such characteristics as payment upon periodic 
demand rather than fixed maturity dates and payment relying on external 
liquidity. The VMIG rating criteria are identical to the MIG criteria 
discussed above. 

                           COMMERCIAL PAPER RATINGS 

   Moody's Commercial Paper ratings are opinions of the ability to repay 
punctually promissory obligations not having an original maturity in excess 
of nine months. These ratings apply to Municipal Commercial Paper as well as 
taxable Commercial Paper. Moody's employs the following three designations, 
all judged to be investment grade, to indicate the relative repayment 
capacity of rated issuers: Prime-1, Prime-2, Prime-3. 

   Issuers rated Prime-1 have a superior capacity for repayment of short-term 
promissory obligations; Issuers rated Prime-2 have a strong capacity for 
repayment of short-term promissory obligations; and Issuers rated Prime-3 
have an acceptable capacity for repayment of short-term promissory 
obligations. Issuers rated Not Prime do not fall within any of the Prime 
rating categories. 

STANDARD & POOR'S CORPORATION ("STANDARD & POOR'S") 
                            MUNICIPAL BOND RATINGS 

   A Standard & Poor's municipal bond rating is a current assessment of the 
creditworthiness of an obligor with respect to a specific obligation. This 
assessment may take into consideration obligors such as guarantors, insurers 
or lessees. 

   The ratings are based on current information furnished by the issuer or 
obtained by Standard & Poor's from other sources it considers reliable. The 
ratings are based, in varying degrees, on the following considerations: (1) 
likelihood of default-capacity and willingness of the obligor as to the 
timely payment of interest and repayment of principal in accordance with the 
terms of the obligation; (2) nature of and provisions of the obligation; and 
(3) protection afforded by, and relative position of the obligation in the 
event of bankruptcy, reorganization or other arrangement under the laws of 
bankruptcy and other laws affecting creditors' rights. 

   Standard & Poor's does not perform an audit in connection with any rating 
and may, on occasion, rely on unaudited financial information. The ratings 
may be changed, suspended or withdrawn as a result of changes in, or 
unavailability of, such information, or for other reasons. 

<TABLE>
<CAPTION>
<S>      <C>
 AAA     Debt rated "AAA" has the highest rating assigned by Standard & Poor's. Capacity to pay interest and repay 
         principal is extremely strong. 
 AA      Debt rated "AA" has a very strong capacity to pay interest and repay principal and differs from the highest-rated 
         issues only in small degree. 
 A       Debt rated "A" has a strong capacity to pay interest and repay principal although they are somewhat more susceptible 
         to the adverse effects of changes in circumstances and economic conditions than debt in higher-rated categories. 

                               34           
<PAGE>
BBB      Debt rated "BBB" is regarded as having an adequate capacity to pay interest and repay principal. Whereas it 
         normally exhibits adequate protection parameters, adverse economic conditions or changing circumstances are 
         more likely to lead to a weakened capacity to pay interest and repay principal for debt in this category than 
         for debt in higher-rated categories. 
         Bonds rated AAA, AA, A and BBB are considered investment grade bonds. 
BB       Debt rated "BB" has less near-term vulnerability to default than other speculative grade debt. However, it 
         faces major ongoing uncertainties or exposure to adverse business, financial or economic conditions which 
         would lead to inadequate capacity or willingness to pay interest and repay principal. 
B        Debt rated "B" has a greater vulnerability to default but presently has the capacity to meet interest payments 
         and principal repayments. Adverse business, financial or economic conditions would likely impair capacity 
         or willingness to pay interest and repay principal. 
CCC      Debt rated "CCC" has a current identifiable vulnerability to default, and is dependent upon favorable business, 
         financial and economic conditions to meet timely payments of interest and repayments of principal. In the 
         event of adverse business, financial or economic conditions, it is not likely to have the capacity to pay 
         interest and repay principal. 
CC       The rating "CC" is typically applied to debt subordinated to senior debt which is assigned an actual or "CCC" 
         rating. 
C        The rating "C" is typically applied to debt subordinated to senior debt which is assigned an actual or implied 
         "CCC-'' debt rating. 
CI       The rating "Cl" is reserved for income bonds on which no interest is being paid. 
NR       Indicates that no rating has been requested, that there is insufficient information on which to base a rating 
         or that Standard & Poor's does not rate a particular type of obligation as a matter of policy. 

         Bonds rated "BB", "B", "CCC" and "C" are regarded as having predominantly speculative characteristics with 
         respect to capacity to pay interest and repay principal. "BB" indicates the least degree of speculation and 
         "C" the highest degree of speculation. While such debt will likely have some quality and protective characteristics, 
         these are outweighed by large uncertainties or major risk exposures to adverse conditions. 

         Plus (+) or minus (-): The ratings from "AA" or "CCC" may be modified by the addition of a plus or minus sign 
         to show relative standing within the major ratings categories. 

         The foregoing ratings are sometimes followed by a "p" which indicates that the rating is provisional. A provisional 
         rating assumes the successful completion of the project being financed by the bonds being rated and indicates 
         that payment of debt service requirements is largely or entirely dependent upon the successful and timely 
         completion of the project. This rating, however, while addressing credit quality subsequent to completion 
         of the project, makes no comment on the likelihood or risk of default upon failure of such completion. 
</TABLE>

                            MUNICIPAL NOTE RATINGS 

   Commencing on July 27, 1984, Standard & Poor's instituted a new rating 
category with respect to certain municipal note issues with a maturity of 
less than three years. The new note ratings denote the following: 

     SP-1 denotes a very strong or strong capacity to pay principal and 
    interest. Issues determined to possess overwhelming safety characteristics 
    are given a plus (+) designation (SP-1 +). 

     SP-2 denotes a satisfactory capacity to pay principal and interest. 

     SP-3 denotes a speculative capacity to pay principal and interest. 

                               35           
<PAGE>
                           COMMERCIAL PAPER RATINGS 

   Standard and Poor's commercial paper rating is a current assessment of the 
likelihood of timely payment of debt having an original maturity of no more 
than 365 days. The commercial paper rating is not a recommendation to 
purchase or sell a security. The ratings are based upon current information 
furnished by the issuer or obtained by S&P from other sources it considers 
reliable. The ratings may be changed, suspended or withdrawn as a result of 
changes in or unavailability of such information. Ratings are graded into 
group categories, ranging from "A" for the highest quality obligations to "D" 
for the lowest. Ratings are applicable to both taxable and tax-exempt 
commercial paper. The categories are as follows: 

     Issuers assigned A ratings are regarded as having the greatest capacity 
   for timely payment. Issues in this category are further refined with the 
   designation 1, 2 and 3 to indicate the relative degree of safety. 

     A-1 indicates that the degree of safety regarding timely payment is very 
    strong. 

     A-2 indicates capacity for timely payment on issues with this designation 
    is strong. However, the relative degree of safety is not as overwhelming 
    as for issues designated "A-1". 

     A-3 indicates a satisfactory capacity for timely payment. Obligations 
    carrying this designation are, however, somewhat more vulnerable to the 
    adverse effects of changes in circumstances than obligations carrying the 
    higher designations.

Item 27.    Indemnification

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

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

    Insofar as indemnification for liabilities arising under the Securities Act
of 1933 (the "Act") may be permitted to trustees, officers and controlling
persons of the Registrant pursuant to the foregoing provisions or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for

                                       2
<PAGE>

indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a trustee, officer, or controlling
person of the Registrant in connection with the successful defense of any
action, suit or proceeding) is asserted against the Registrant by such trustee,
officer or controlling person in connection with the shares being registered,
the Registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question whether such indemnification by it is against public policy as
expressed in the Act, and will be governed by the final adjudication of such
issue.

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

                                       OF

                    DEAN WITTER TAX-FREE DAILY INCOME TRUST
                  AMENDED AND RESTATED AS OF OCTOBER 23, 1997

                                   ARTICLE I
                                  DEFINITIONS

   The terms "Commission," "Declaration," "Distributor," "Investment 
Adviser," "Majority Shareholder Vote," "1940 Act," "Shareholder," "Shares," 
"Transfer Agent," "Trust," "Trust Property," and "Trustees" have the 
respective meanings given them in the Declaration of Trust of Dean Witter 
Tax-Free Daily Income Trust (formerly known as Dean Witter/Sears Tax-Free 
Daily Income Trust) dated April 6, 1987, as amended from time to time. 

                                   ARTICLE II
                                    OFFICES

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

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

                                  ARTICLE III
                             SHAREHOLDERS' MEETINGS

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

   SECTION 3.2. Meetings. Meetings of Shareholders of the Trust shall be held 
whenever called by the Trustees or the President of the Trust and whenever 
election of a Trustee or Trustees by Shareholders is required by the 
provisions of Section 16(a) of the 1940 Act, for that purpose. Meetings of 
Shareholders shall also be called by the Secretary upon the written request 
of the holders of Shares entitled to vote not less than twenty-five percent 
(25%) of all the votes entitled to be cast at such meeting except to the 
extent otherwise required by Section 16(c) of the 1940 Act, as made 
applicable to the Trust by the provisions of Section 2.3 of the Declaration. 
Such request shall state the purpose or purposes of such meeting and the 
matters proposed to be acted on thereat. The Secretary shall inform such 
Shareholders of the reasonable estimated cost of preparing and mailing such 
notice of the meeting, and upon payment to the Trust of such costs, the 
Secretary shall give notice stating the purpose or purposes of the meeting to 
all entitled to vote at such meeting. No meeting need be called upon the 
request of the holders of Shares entitled to cast less than a majority of all 
votes entitled to be cast at such meeting, to consider any matter which is 
substantially the same as a matter voted upon at any meeting of Shareholders 
held during the preceding twelve months. 

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

<PAGE>

   SECTION 3.4. Quorum and Adjournment of Meetings. Except as otherwise 
provided by law, by the Declaration or by these By-Laws, at all meetings of 
Shareholders, the holders of a majority of the Shares issued and outstanding 
and entitled to vote thereat, present in person or represented by proxy, 
shall be requisite and shall constitute a quorum for the transaction of 
business. In the absence of a quorum, the Shareholders present or represented 
by proxy and entitled to vote thereat shall have the power to adjourn the 
meeting from time to time. The Shareholders present in person or represented 
by proxy at any meeting and entitled to vote thereat also shall have the 
power to adjourn the meeting from time to time if the vote required to 
approve or reject any proposal described in the original notice of such 
meeting is not obtained (with proxies being voted for or against adjournment 
consistent with the votes for and against the proposal for which the required 
vote has not been obtained). The affirmative vote of the holders of a 
majority of the Shares then present in person or represented by proxy shall 
be required to adjourn any meeting. Any adjourned meeting may be reconvened 
without further notice or change in record date. At any reconvened meeting at 
which a quorum shall be present, any business may be transacted that might 
have been transacted at the meeting as originally called. 

   SECTION 3.5. Voting Rights, Proxies. At each meeting of Shareholders, each 
holder of record of Shares entitled to vote thereat shall be entitled to one 
vote in person or by proxy, executed in writing by the Shareholder or his 
duly authorized attorney-in-fact, for each Share of beneficial interest of 
the Trust and for the fractional portion of one vote for each fractional 
Share entitled to vote so registered in his name on the records of the Trust 
on the date fixed as the record date for the determination of Shareholders 
entitled to vote at such meeting. No proxy shall be valid after eleven months 
from its date, unless otherwise provided in the proxy. At all meetings of 
Shareholders, unless the voting is conducted by inspectors, all questions 
relating to the qualification of voters and the validity of proxies and the 
acceptance or rejection of votes shall be decided by the chairman of the 
meeting. Pursuant to a resolution of a majority of the Trustees, proxies may 
be solicited in the name of one or more Trustees or Officers of the Trust. 

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

   SECTION 3.7. Inspectors of Election. In advance of any meeting of 
Shareholders, the Trustees may appoint Inspectors of Election to act at the 
meeting or any adjournment thereof. If Inspectors of Election are not so 
appointed, the chairman of any meeting of Shareholders may, and on the 
request of any Shareholder or his proxy shall, appoint Inspectors of Election 
of the meeting. In case any person appointed as Inspector fails to appear or 
fails or refuses to act, the vacancy may be filled by appointment made by the 
Trustees in advance of the convening of the meeting or at the meeting by the 
person acting as chairman. The Inspectors of Election shall determine the 
number of Shares outstanding, the Shares represented at the meeting, the 
existence of a quorum, the authenticity, validity and effect of proxies, 
shall receive votes, ballots or consents, shall hear and determine all 
challenges and questions in any way arising in connection with the right to 
vote, shall count and tabulate all votes or consents, determine the results, 
and do such other acts as may be proper to conduct the election or vote with 
fairness to all Shareholders. On request of the chairman of the meeting, or 
of any Shareholder or his proxy, the Inspectors of Election shall make a 
report in writing of any challenge or question or matter determined by them 
and shall execute a certificate of any facts found by them. 

   SECTION 3.8. Inspection of Books and Records. Shareholders shall have such 
rights and procedures of inspection of the books and records of the Trust as 
are granted to Shareholders under the Corporations and Associations Law of 
the State of Maryland. 

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

                                       2
<PAGE>

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

                                   ARTICLE IV
                                    TRUSTEES

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

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

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

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

   SECTION 4.5. Action by Trustees Without Meeting. The provisions of these 
By-Laws covering notices and meetings to the contrary notwithstanding, and 
except as required by law, any action required or permitted to be taken at 
any meeting of the Trustees may be taken without a meeting if a consent in 
writing setting forth the action shall be signed by all of the Trustees 
entitled to vote upon the action and such written consent is filed with the 
minutes of proceedings of the Trustees. 

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

   SECTION 4.7.  Execution of Instruments and Documents and Signing of Checks 
and Other Obligations and Transfers. All instruments, documents and other 
papers shall be executed in the name and on behalf of the Trust and all 
checks, notes, drafts and other obligations for the payment of money by the 
Trust shall be signed, and all transfer of securities standing in the name of 
the Trust shall be executed, by the Chairman, the President, any Vice 
President or the Treasurer or by any one or more officers or agents of the 
Trust as shall be designated for that purpose by vote of the Trustees; 
notwithstanding the above, nothing in this Section 4.7 shall be deemed to 
preclude the electronic authorization, by designated persons, of the Trust's 
Custodian (as described herein in Section 9.1) to transfer assets of the 
Trust, as provided for herein in Section 9.1.

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

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

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

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

       (2) The determination shall be made: 

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

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

           (iii) By the Shareholders. 

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

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

                                       4
<PAGE>

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

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

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

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

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

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

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

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

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

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

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

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

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

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

   SECTION 5.1. Executive and Other Committees. The Trustees, by resolution 
adopted by a majority of the Trustees, may designate an Executive Committee 
and/or committees, each committee to consist of two (2) or more of the 
Trustees of the Trust and may delegate to such committees, in the intervals 
between meetings of the Trustees, any or all of the powers of the Trustees in 
the management of the business and affairs of the Trust. In the absence of 
any member of any such committee, the members thereof present 

                                       5
<PAGE>

Trustee to act in place of such absent member. Each such committee shall keep 
a record of its proceedings. 

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

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

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

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

                                   ARTICLE VI

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

                          DIVIDENDS AND DISTRIBUTIONS

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

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

                                  ARTICLE VIII
                             CERTIFICATES OF SHARES

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

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

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

   SECTION 8.2. Lost, Stolen, Destroyed and Mutilated Certificates. The 
Trustees may direct a new certificate or certificates to be issued in place 
of any certificate or certificates theretofore issued by the Trust alleged to 
have been lost, stolen or destroyed, upon satisfactory proof of such loss, 
theft, or destruction; and the Trustees may, in their discretion, require the 
owner of the lost, stolen or destroyed certificate, or his legal 
representative, to give to the Trust and to such Registrar, Transfer Agent 
and/or Transfer Clerk as may be authorized or required to countersign such 
new certificate or certificates, a bond in such sum and of such type as they 
may direct, and with such surety or sureties, as they may direct, as 
indemnity against any claim that may be against them or any of them on 
account of or in connection with the alleged loss, theft or destruction of 
any such certificate. 

                                   ARTICLE IX
                                   CUSTODIAN

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

                                       8
<PAGE>

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

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

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

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

   The Trustees may also authorize the custodian to employ one or more 
sub-custodians from time to time to perform such of the acts and services of 
the custodian and upon such terms and conditions as may be agreed upon 
between the custodian and such sub-custodian and approved by the Trustees. 

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

                                   ARTICLE X
                                WAIVER OF NOTICE

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

                                   ARTICLE XI
                                 MISCELLANEOUS

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

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

                                       9
<PAGE>

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

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

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

                                  ARTICLE XII
                      COMPLIANCE WITH FEDERAL REGULATIONS

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

                                   AMENDMENTS

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

                                  ARTICLE XIV
                              DECLARATION OF TRUST

   The Declaration of Trust establishing Dean Witter Tax-Free Daily Income 
Trust, dated April 6, 1987, together with all amendments thereto, a copy of 
which is on file in the office of the Secretary of the Commonwealth of 
Massachusetts, provides that the name Dean Witter Tax-Free Daily Income Trust

its duties hereunder; shall continuously manage the assets of the Fund in a

including the pricing of Fund shares, and preparation of prospectuses, proxy
statements and reports required to be filed with Federal and state securities
commissions (except insofar as the participation or assistance of independent
accountants and attorneys is, in the opinion of the Investment Manager,
necessary or desirable). The Investment Manager shall also bear the cost of
telephone service, heat, light, power and other utilities provided to the Fund,
and the cost of printing (in excess of costs borne by the Fund) and
distributing prospectuses and supplements thereto of the Fund used for sales
purposes.

         5. The Fund assumes and shall pay or cause to be paid all other
expenses of the Fund, including without limitation: the charges and expenses of
any registrar, any custodian or depository appointed by the Fund for the
safekeeping of its cash, portfolio securities and other property, and any stock
transfer or dividend agent or agents appointed by the Fund; brokers'

other governmental agencies; the cost and expense of engraving or printing

and other jurisdictions (including filing fees and legal fees and disbursements

distributing prospectuses of the Fund and supplements thereto to the Fund's
shareholders; all expenses of shareholders' and Trustees' meetings and of
preparing, printing and mailing proxy statements and reports to shareholders
and prospective shareholders; fees and travel expenses of Trustees or members
of any advisory board or committee who are not employees of the Investment
Manager or any corporate affiliate of the Investment Manager; all expenses
incident to the payment of any dividend, distribution, withdrawal or
redemption, whether in shares or in cash; charges and expenses of legal counsel
and independent accountants in connection with any matter relating to the Fund
(not including compensation or expenses of attorneys employed by the Investment
Manager); membership dues of the Investment Company Institute; interest payable
on Fund borrowings; postage; insurance premiums on property or personnel
(including officers and Trustees) of the Fund which inure to its benefit;
extraordinary expenses (including but not limited to legal claims and
liabilities and litigation costs and any indemnification related thereto); and
all other charges and costs of the Fund's operation unless otherwise explicitly
provided herein.

         6. For the services to be rendered, the facilities furnished, and the
expenses assumed by the Investment Manager, the Fund shall pay to the
Investment Manager monthly compensation determined by applying the following
annual rates to the Fund's daily net assets: 0.50% of the portion of the daily
net assets not exceeding $500 million; 0.425% of the portion of the daily net
assets exceeding $500 million but not exceeding $750 million; 0.375% of the
portion of the daily net assets exceeding $750 million but not exceeding $1
billion; 0.35% of the portion of the daily net assets exceeding $1 billion but
not exceeding $1.5 billion; 0.325% of the portion of the daily net assets
exceeding $1.5 billion but not exceeding $2 billion; 0.30% of the portion of
the daily net assets exceeding $2 billion but not exceeding $2.5 billion;
0.275% of the portion of the daily net assets exceeding $2.5 billion but not
exceeding $3 billion; and 0.25% of the portion of the daily net assets
exceeding $3 billion. Except as hereinafter set forth, compensation under this
Agreement shall be calculated and accrued daily and the amounts of the daily
accruals shall be paid monthly. Such calculations shall be made by applying
1/365ths of the annual rates to the Fund's net assets each day determined as of
the close of business on that day or the last previous business day. If this
Agreement becomes effective subsequent to the first day of a month or shall
terminate before the last day of a month, compensation for that part of the
month this Agreement is in effect shall be prorated in a manner consistent with
the calculation of the fees as set forth above. Subject to the provisions of
paragraph 7 hereof, payment of the Investment Manager's compensation for the
preceding month shall be made as promptly as possible after completion of the
computation contemplated by paragraph 7 hereof.

         7. In the event the operating expenses of the Fund, including amounts
payable to the Investment Manager pursuant to paragraph 6 hereof, for any
fiscal year ending on a date on which this Agreement is in effect, exceed the
expense limitations applicable to the Fund imposed by state securities laws or
regulations thereunder, as such limitations may be raised or lowered from time
to time, the Investment Manager shall reduce its management fee to the extent
of such excess and, if required, pursuant to any such laws or

                                       2
<PAGE>

regulations, will reimburse the Fund for annual operating expenses in excess of
any expense limitation that may be applicable; provided, however, there shall
be excluded from such expenses the amount of any interest, taxes, brokerage
commissions and extraordinary expenses (to the extent permitted by state
securities laws or regulations thereunder) paid or payable by the Fund. Such
reduction, if any, shall be computed and accrued daily, shall be settled on a
monthly basis, and shall be based upon the expense limitation applicable to the
Fund as at the end of the last business day of the month. Should two or more
such expense limitations be applicable as at the end of the last business day
of the month, that expense limitation which results in the largest reduction in
the Investment Manager's fee shall be applicable.

         For purposes of this provision, should any applicable expense
limitation be based upon the gross income of the Fund, such gross income shall
include, but not be limited to, interest on debt of fixed income securities in
the Fund's portfolio accrued to and including the last day of the Fund's fiscal
year, and dividends declared but not paid on any equity securities in the
Fund's portfolio, the record dates for which fall on or prior to the last day
of such fiscal year, but shall not include gains from the sales of securities.

         8. The Investment Manager will use its best efforts in the supervision
and management of the investment activities of the Fund, but in the absence of
willful misfeasance, bad faith, gross negligence or reckless disregard of its
obligations hereunder, the Investment Manager shall not be liable to the Fund
or any of its investors for any error of judgment or mistake of law or for any
act or omission by the Investment Manager or for any losses sustained by the
Fund or its investors.

         9. Nothing contained in this Agreement shall prevent the Investment
Manager or any affiliated person of the Investment Manager from acting as
investment adviser or manager for any other person, firm or corporation and
shall not in any way bind or restrict the Investment Manager or any such
affiliated person from buying, selling or trading any securities or commodities
for their own accounts or for the account of others for whom they may be
acting. Nothing in this Agreement shall limit or restrict the right of any
director, officer or employee of the Investment Manager to engage in any other
business or to devote his or her time and attention in part to the management
or other aspects of any other business whether of a similar or dissimilar
nature.

         10. This Agreement shall remain in effect until April 30, 1999 and
from year to year thereafter provided such continuance is approved at least
annually by the vote of holders of a majority (as defined in the Act) of the
outstanding voting securities of the Fund or by the Board of Trustees of the
Fund; provided that in either event such continuance is also approved annually
by the vote of a majority of the Trustees of the Fund who are not parties to
this Agreement or "interested persons" (as defined in the Act) of any such
party, which vote must be cast in person at a meeting called for the purpose of
voting on such approval; provided, however, that (a) the Fund may, at any time
and without the payment of any penalty, terminate this Agreement upon thirty
days' written notice to the Investment Manager, either by majority vote of the
Board of Trustees of the Fund or by the vote of a majority of the outstanding
voting securities of the Fund; (b) this Agreement shall immediately terminate
in the event of its assignment (within the meaning of the Act) unless such
automatic termination shall be prevented by an exemptive order of the
Securities and Exchange Commission; and (c) the Investment Manager may
terminate this Agreement without payment of penalty on thirty days' written
notice to the Fund. Any notice under this Agreement shall be given in writing,
addressed and delivered, or mailed post-paid, to the other party at the
principal office of such party.

         11. This Agreement may be amended by the parties without the vote or
consent of shareholders of the Fund to supply any omission, to cure, correct or
supplement any ambiguous, defective or inconsistent provision hereof, or if
they deem it necessary to conform this Agreement to the requirements of
applicable federal laws or regulations, but neither the Fund nor the Investment
Manager shall be liable for failing to do so.

         12. This Agreement shall be construed in accordance with the law of
the State of New York and the applicable provisions of the Act. To the extent
the applicable law of the State of New York, or any of the provisions herein,
conflicts with the applicable provisions of the Act, the latter shall control.

                                       3

         13. The Investment Manager and the Fund each agree that the name "Dean
Witter," which comprises a component of the Fund's name, is a property right of
Dean Witter Reynolds Inc. The Fund agrees and consents that (i) it will only
use the name "Dean Witter" as a component of its name and for no other purpose,
(ii) it will not purport to grant to any third party the right to use the name
"Dean Witter" for any purpose, (iii) the Investment Manager or its parent,
Morgan Stanley, Dean Witter, Discover & Co., or any corporate affiliate of the
Investment Manager's parent, may use or grant to others the right to use the

portion of a corporate or business name or for any commercial purpose,
including a grant of such right to any other investment company, (iv) at the
request of the Investment Manager or its parent, the Fund will take such action
as may be required to provide its consent to the use of the name "Dean Witter,"
or any combination or abbreviation thereof, by the Investment Manager or its
parent or any corporate affiliate of the Investment Manager's parent, or by any
person to whom the Investment Manager or its parent or any corporate affiliate
of the Investment Manager's parent shall have granted the right to such use,
and (v) upon the termination of any investment advisory agreement into which
the Investment Manager and the Fund may enter, or upon termination of
affiliation of the Investment Manager with its parent, the Fund shall, upon
request by the Investment Manager or its parent, cease to use the name "Dean
Witter" as a component of its name, and shall not use the name, or any
combination or abbreviation thereof, as a part of its name or for any other
commercial purpose, and shall cause its officers, Trustees and shareholders to
take any and all actions which the Investment Manager or its parent may request
to effect the foregoing and to reconvey to the Investment Manager or its parent
any and all rights to such name.

         14. The Declaration of Trust establishing Dean Witter Tax-Free Daily
Income Trust, dated April 6, 1987, a copy of which, together with all
amendments thereto (the "Declaration"), is on file in the office of the
Secretary of the Commonwealth of Massachusetts, provides that the name Dean
Witter Tax-Free Daily Income Trust refers to the Trustees under the Declaration
collectively as Trustees, but not as individuals or personally; and no Trustee,
shareholder, officer, employee or agent of Dean Witter Tax-Free Daily Income
Trust shall be held to any personal liability, nor shall resort be had to their
private property for the satisfaction of any obligation or claim or otherwise,
in connection with the affairs of said Dean Witter Tax-Free Daily Income Trust,
but the Trust Estate only shall be liable.

                             DISTRIBUTION AGREEMENT

   AGREEMENT made as of this 31st day of May, 1997 between Dean Witter 
Tax-Free Daily Income Trust, an unincorporated business trust organized under 
the laws of the Commonwealth of Massachusetts (the "Fund"), and Dean Witter 
Distributors Inc., a Delaware corporation (the "Distributor"); 

                              W I T N E S S E T H:

   WHEREAS, the Fund is registered under the Investment Company Act of 1940, 
as amended (the "1940 Act"), as a diversified open-end investment company and 
it is in the interest of the Fund to offer its shares for sale continuously, 
and 

   WHEREAS, the Fund and the Distributor wish to enter into an agreement with 
each other with respect to the continuous offering of the Fund's transferable 
shares of beneficial interest, of $.01 par value (the "Shares"), in order to 
promote the growth of the Fund and facilitate the distribution of its Shares. 

   NOW, THEREFORE, the parties agree as follows: 

   SECTION 1. Appointment of the Distributor. (a) The Fund hereby appoints 
the Distributor as the principal underwriter of the Fund to sell Shares to 
the public on the terms set forth in this Agreement and the Fund's prospectus 
and the Distributor hereby accepts such appointment and agrees to act 
hereunder. The Fund, during the term of this Agreement, shall sell Shares to 
the Distributor upon the terms and conditions set forth herein. 

   (b) The Distributor agrees to purchase Shares, as principal for its own 
account, from the Fund and to sell Shares as principal to investors and 
securities dealers, including Dean Witter Reynolds Inc. ("DWR"), an affiliate 
of the Distributor, upon the terms described herein and in the Fund's 
prospectus (the "Prospectus") and statement of additional information 
included in the Fund's registration statement (the "Registration Statement") 
most recently filed from time to time with the Securities and Exchange 
Commission (the "SEC") and effective under the Securities Act of 1933, as 
amended (the "1933 Act"), and 1940 Act or as said Prospectus may be otherwise 
amended or supplemented and filed with the SEC pursuant to Rule 497 under the 
1933 Act. 

   SECTION 2. Exclusive Nature of Duties. The Distributor shall be the 
exclusive principal underwriter and distributor of the Fund, except that the 
exclusive rights granted to the Distributor to sell the Shares shall not 
apply to Shares issued by the Fund: (i) in connection with the merger or 
consolidation of any other investment company or personal holding company 
with the Fund or the acquisition by purchase or otherwise of all (or 
substantially all) the assets or the outstanding shares of any such company 
by the Fund; or (ii) pursuant to reinvestment of dividends or capital gains 
distributions; or (iii) pursuant to the reinstatement privilege afforded 
redeeming shareholders. 

   SECTION 3. Purchase of Shares from the Fund. (a) The Distributor shall 
have the right to buy from the Fund the Shares needed, but not more than the 
Shares needed (except for clerical errors in transmission), to fill 
unconditional orders for Shares placed with the Distributor by investors and 
securities dealers. The price which the Distributor shall pay for the Shares 
so purchased from the Fund shall be the net asset value, determined as set 
forth in the Prospectus, used in determining the public offering price on 
which such orders were based. 

   (b) The Shares are to be resold by the Distributor at the public offering 
price, as set forth in the Prospectus, to investors or to securities dealers, 
including DWR, having selected dealer agreements with the Distributor 
pursuant to Section 7 ("Selected Dealers"). 

   (c) The Fund shall have the right to suspend the sale of the Shares at 
times when redemption is suspended pursuant to the conditions set forth in 
Section 4(e) hereof. The Fund shall also have the right to suspend the sale 
of the Shares if trading on the New York Stock Exchange shall have been 
suspended, if a banking moratorium shall have been declared by federal or New 
York authorities, or if there shall have been some other extraordinary event 
which, in the judgment of the Fund, makes it impracticable to sell the 
Shares. 

<PAGE>

   (d) The Fund, or any agent of the Fund designated in writing by the Fund, 
shall be promptly advised of all purchase orders for Shares received by the 
Distributor. Any order may be rejected by the Fund; provided, however, that 
the Fund will not arbitrarily or without reasonable cause refuse to accept 
orders for the purchase of Shares. The Distributor will confirm orders upon 
their receipt, and the Fund (or its agent) upon receipt of payment therefor 
and instructions will deliver share certificates for such Shares or a 
statement confirming the issuance of Shares. Payment shall be made to the 
Fund in New York Clearing House funds. The Distributor agrees to cause such 
payment and such instructions to be delivered promptly to the Fund (or its 
agent). 

   (e) With respect to Shares sold by any Selected Dealer, the Distributor is 
authorized to direct the Fund's transfer agent to receive instructions 
directly from the Selected Dealer on behalf of the Distributor as to 
registration of Shares in the names of investors and to confirm issuance of 
the Shares to such investors. The Distributor is also authorized to instruct 
the transfer agent to receive payment directly from the Selected Dealer on 
behalf of the Distributor, for prompt transmittal to the Fund's custodian, of 
the purchase price of the Shares. In such event the Distributor shall obtain 
from the Selected Dealer and maintain a record of such registration 
instructions and payments. 

   SECTION 4. Repurchase or Redemption of Shares. (a) Any of the outstanding 
Shares may be tendered for redemption at any time, and the Fund agrees to 
redeem the Shares so tendered in accordance with the applicable provisions 
set forth in the Prospectus. The price to be paid to redeem the Shares shall 
be equal to the net asset value determined as set forth in the Prospectus. 
All payments by the Fund hereunder shall be made in the manner set forth 
below. 

   The proceeds of any redemption of Shares shall be paid by the Fund to the 
redeeming shareholders, in each case in accordance with applicable provisions 
of the Prospectus in New York Clearing House funds. 

   (b) The Distributor is authorized, as agent for the Fund, to repurchase 
Shares, represented by a share certificate which is delivered to any office 
of the Distributor in accordance with applicable provisions set forth in the 
Prospectus. The Distributor shall promptly transmit to the transfer agent of 
the Fund for redemption all Shares so delivered. The Distributor shall be 
responsible for the accuracy of instructions transmitted to the Fund's 
transfer agent in connection with all such repurchases. 

   (c) The Distributor is authorized, as agent for the Fund, to repurchase 
Shares held in a shareholder's account with the Fund for which no share 
certificate has been issued, upon the telephonic or telegraphic request of 
the shareholder, or at the discretion of the Distributor. The Distributor 
shall promptly transmit to the transfer agent of the Fund, for redemption, 
all such orders for repurchase of Shares. Payment for Shares repurchased may

repurchases. 

   (d) With respect to Shares tendered for redemption or repurchase by any 
Selected Dealer on behalf of its customers, the Distributor is authorized to 
instruct the transfer agent of the Fund to accept orders for redemption or 
repurchase directly from the Selected Dealer on behalf of the Distributor and

repurchases directly to the Selected Dealer on behalf of the Distributor for 
the account of the shareholder. The Distributor shall obtain from the 
Selected Dealer, and shall maintain, a record of such orders. The Distributor 
is further authorized to obtain from the Fund and shall maintain, a record of 
payments made directly to the Selected Dealer on behalf of the Distributor. 

   (e) Redemption of Shares or payment by the Fund may be suspended at times 
when the New York Stock Exchange is closed, when trading on said Exchange is 
restricted, when an emergency exists as a result of which disposal by the 
Fund of securities owned by it is not reasonably practicable or it is not 
reasonably practicable for the Fund fairly to determine the value of its net 
assets, or during any other period when the SEC, by order, so permits. 

   SECTION 5. Duties of the Fund. (a) The Fund shall furnish to the 
Distributor copies of all information, financial statements and other papers

   (c) The Fund shall use its best efforts to pay the filing fees for an 
appropriate number of the Shares for sale under the securities laws of such 
states as the Distributor and the Fund may approve. Any qualification to sell

specific number of Shares. The services of the Distributor hereunder are not

other registered investment companies. 

   (b) Neither the Distributor nor any Selected Dealer shall give any 
information or make any representations, other than those contained in the

statements therein not misleading, unless such statement or omission was made

in connection therewith by or on behalf of the Distributor; provided, 
however, that in no case (i) is the indemnity of the Fund in favor of the 
Distributor and any such controlling persons to be deemed to protect the 
Distributor or any such controlling persons thereof against any liability to 
the Fund or its security holders to which the Distributor or any such 
controlling persons would otherwise be subject by reason of willful 
misfeasance, bad faith or gross negligence in the performance of its duties 
or by reason of reckless disregard of its obligations and duties under this 
Agreement; or (ii) is the Fund to be liable under its indemnity agreement 
contained in this paragraph with respect to any claim made against the 
Distributor or any such controlling persons, unless the Distributor or any 
such controlling persons, as the case may be, shall have notified the Fund in 
writing within a reasonable time after the summons or other first legal 
process giving information of the nature of the claim shall have been served 
upon the Distributor or such controlling persons (or after the Distributor or 
such controlling persons shall have received notice of such service on any 
designated agent), but failure to notify the Fund of any such claim shall not 
relieve it from any liability which it may have to the person against whom 
such action is brought otherwise than on account of its indemnity agreement 
contained in this paragraph. The Fund will be entitled to participate at its 
own expense in the defense or if it so elects, to assume the defense, of any 
suit brought to enforce any such liability, but if the Fund elects to assume 
the defense, such defense shall be conducted by counsel chosen by it and 
satisfactory to the Distributor or such controlling person or persons, 
defendant or defendants in the suit. In the event the Fund elects to assume 
the defense of any such suit and retain such counsel, the Distributor or such 
controlling person or persons, defendant or defendants in the suit, shall 
bear the fees and expenses of any additional counsel retained by them, but, 
in case the Fund does not elect to assume the defense of any such suit, it 
will reimburse the Distributor or such controlling person or persons, 
defendant or defendants in the suit, for the reasonable fees and expenses of 
any counsel retained by them. The Fund shall promptly notify the Distributor 
of the commencement of any litigation or proceedings against it or any of its 
officers or trustees in connection with the issuance or sale of the Shares. 

   (b) (i) The Distributor shall indemnify and hold harmless the Fund and 
each of its Trustees and officers and each person, if any, who controls the 
Fund against any loss, liability, claim, damage or expense described in the 
foregoing indemnity contained in subsection (a) of this Section, but only 
with respect to statements or omissions made in reliance upon, and in 
conformity with, information furnished to the Fund in writing by or on behalf 
of the Distributor for use in connection with the Registration Statement or 
related Prospectus, as from time to time amended, or the annual or interim 
reports to shareholders. 

                                       4
<PAGE>

   (ii) The Distributor shall indemnify and hold harmless the Fund and the 
Fund's transfer agent, individually and in its capacity as the Fund's 
transfer agent, from and against any claims, damages and liabilities which 
arise as a result of actions taken pursuant to instructions from, or on 
behalf of the Distributor to: (1) redeem all or a part of shareholder 
accounts in the Fund pursuant to Section 4 hereof and pay the proceeds to the 
Distributor for the account of each shareholder whose Shares are so redeemed; 
and (2) register Shares in the names of investors, confirm the issuance 
thereof and receive payment therefor pursuant to Section 3(e). 

   (iii) In case any action shall be brought against the Fund or any person 
so indemnified by this subsection 9(b) in respect of which indemnity may be 
sought against the Distributor, the Distributor shall have the rights and 
duties given to the Fund, and the Fund and each person so indemnified shall 
have the rights and duties given to the Distributor by the provisions of 
subsection (a) of this Section 9. 

   (c) If the indemnification provided for in this Section 9 is unavailable 
or insufficient to hold harmless an indemnified party under subsection (a) or 
(b) above in respect of any losses, claims, damages, liabilities or expenses 
(or actions in respect thereof) referred to herein, then each indemnifying 
party shall contribute to the amount paid or payable by such indemnified 
party as a result of such losses, claims, damages, liabilities or expenses 
(or actions in respect thereof) in such proportion as is appropriate to 
reflect the relative benefits received by the Fund on the one hand and the 
Distributor on the other from the offering of the Shares. If, however, the 
allocation provided by the immediately preceding sentence is not permitted by 
applicable law, then each indemnifying party shall contribute to such amount 
paid or payable by such indemnified party in such proportion as is 
appropriate to reflect not only such relative benefits but also the relative 
fault of the Fund on the one hand and the Distributor on the other in 
connection with the statements or omissions which resulted in such losses, 
claims, damages, liabilities or expenses (or actions in respect thereof), as 
well as any other relevant equitable considerations. The relative benefits 
received by the Fund on the one hand and the Distributor on the other shall 
be deemed to be in the same proportion as the total net proceeds from the 
offering (before deducting expenses) received by the Fund bear to the total 
compensation received by the Distributor, in each case as set forth in the 
Prospectus. The relative fault shall be determined by reference to, among 
other things, whether the untrue or alleged untrue statement of a material 
fact or the omission or alleged omission to state a material fact relates to 
information supplied by the Fund or the Distributor and the parties' relative 
intent, knowledge, access to information and opportunity to correct or 
prevent such statement or omission. The Fund and the Distributor agree that 
it would not be just and equitable if contribution were determined by pro 
rata allocation or by any other method of allocation which does not take into 
account the equitable considerations referred to above. The amount paid or 
payable by an indemnified party as a result of the losses, claims, damages, 
liabilities or expenses (or actions in respect thereof) referred to above 
shall be deemed to include any legal or other expenses reasonably incurred by 
such indemnified party in connection with investigating or defending any such 
claim. Notwithstanding the provisions of this subsection (c), the Distributor 
shall not be required to contribute any amount in excess of the amount by 
which the total price at which the Shares distributed by it to the public 
were offered to the public exceeds the amount of any damages which it has 
otherwise been required to pay by reason of such untrue or alleged untrue 
statement or omission or alleged omission. No person guilty of fraudulent 
misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall 
be entitled to contribution from any person who was not guilty of such 
fraudulent misrepresentation. 

   SECTION 10. Duration and Termination of this Agreement. This Agreement 
shall become effective as of the date first above written and shall remain in 
force until April 30, 1998, and thereafter, but only so long as such 
continuance is specifically approved at least annually by (i) the Trustees of 
the Fund, or by the vote of a majority of the outstanding voting securities 
of the Fund, cast in person or by proxy, and (ii) a majority of those 
Trustees who are not parties to this Agreement or interested persons of any 
such party and who have no direct or indirect financial interest in this 
Agreement or in the operation of the Fund's Rule 12b-1 Plan or in any 
agreement related thereto, cast in person at a meeting called for the purpose 
of voting upon such approval. 

   This Agreement may be terminated at any time, without the payment of any 
penalty, by the Trustees of the Fund, by a majority of the Trustees of the 
Fund who are not interested persons of the Fund and 

                                       5
<PAGE>

who have no direct or indirect financial interest in this Agreement, or by 
vote of a majority of the outstanding voting securities of the Fund, or by 
the Distributor, on sixty days' written notice to the other party. This 
Agreement shall automatically terminate in the event of its assignment. 

   The terms "vote of a majority of the outstanding voting securities," 
"assignment" and "interested person," when used in this Agreement, shall have 
the respective meanings specified in the 1940 Act. 

   SECTION 11. Amendments of this Agreement. This Agreement may be amended by 
the parties only if such amendment is specifically approved by (i) the 
Trustees of the Fund, or by the vote of a majority of outstanding voting 
securities of the Fund, and (ii) a majority of those Trustees of the Fund who 
are not parties to this Agreement or interested persons of any such party and 
who have no direct or indirect financial interest in this Agreement or in any 
Agreement related to the Fund's Rule 12b-1 Plan, cast in person at a meeting 
called for the purpose of voting on such approval. 

   SECTION 12. Governing Law. This Agreement shall be construed in accordance 
with the law of the State of New York and the applicable provisions of the 
1940 Act. To the extent the applicable law of the State of New York, or any 
of the provisions herein, conflict with the applicable provisions of the 1940 
Act, the latter shall control. 

   SECTION 13. Personal Liability. The Declaration of the Trust establishing 
Dean Witter Tax-Free Daily Income Trust, dated April 30, 1987, a copy of 
which, together with all amendments thereto (the "Declaration"), is on file 
in the office of the Secretary of the Commonwealth of Massachusetts, provides 
that the name Dean Witter Tax-Free Daily Income Trust refers to the Trustees 
under the Declaration collectively as Trustees, but not as individuals or 
personally; and no Trustee, shareholder, officer, employee or agent of Dean 
Witter Tax-Free Daily Income Trust shall be held to any personal liability, 
nor shall resort be had to their private property for the satisfaction of any 
obligation or claim or otherwise, in connection with the affairs of said Dean 
Witter Tax-Free Daily Income Trust, but the Trust Estate only shall be 
liable. 

   IN WITNESS WHEREOF, the parties hereto have executed and delivered this 
Agreement as of the day and year first written in New York, New York.

   WHEREAS, the Fund desires to appoint DWTFSB as its transfer agent, 
dividend disbursing agent and shareholder servicing agent and DWTFSB desires 
to accept such appointment; 

   NOW THEREFORE, in consideration of the mutual covenants herein contained, 
the parties hereto agree as follows: 

Article 1 Terms of Appointment; Duties of DWTFSB 

   1.1 Subject to the terms and conditions set forth in this Agreement, the 
Fund hereby employs and appoints DWTFSB to act as, and DWTFSB agrees to act 
as, the transfer agent for each series and class of shares of the Fund, 
whether now or hereafter authorized or issued ("Shares"), dividend disbursing 
agent and shareholder servicing agent in connection with any accumulation, 
open-account or similar plans provided to the holders of such Shares 
("Shareholders") and set out in the currently effective prospectus and 
statement of additional information ("prospectus") of the Fund, including 
without limitation any periodic investment plan or periodic withdrawal 
program. 

   1.2 DWTFSB agrees that it will perform the following services: 

     (a) In accordance with procedures established from time to time by 
    agreement between the Fund and DWTFSB, DWTFSB shall: 

        (i)  Receive for acceptance, orders for the purchase of Shares, and 
       promptly deliver payment and appropriate documentation therefor to the 
       custodian of the assets of the Fund (the "Custodian"); 

        (ii) Pursuant to purchase orders, issue the appropriate number of 
       Shares and issue certificates therefor or hold such Shares in book 
       form in the appropriate Shareholder account; 

        (iii) Receive for acceptance redemption requests and redemption 
       directions and deliver the appropriate documentation therefor to the 
       Custodian; 

        (iv) At the appropriate time as and when it receives monies paid to 
       it by the Custodian with respect to any redemption, pay over or cause 
       to be paid over in the appropriate manner such monies as instructed by 
       the redeeming Shareholders; 

        (v) Effect transfers of Shares by the registered owners thereof upon 
       receipt of appropriate instructions; 

        (vi) Prepare and transmit payments for dividends and distributions 
       declared by the Fund; 

        (vii) Calculate any sales charges payable by a Shareholder on 
       purchases and/or redemptions of Shares of the Fund as such charges may

        (viii) Maintain records of account for and advise the Fund and its 
       Shareholders as to the foregoing; and 

        (ix) Record the issuance of Shares of the Fund and maintain pursuant

       Act") a record of the total number of Shares of the Fund which are 
       authorized, based upon data provided to it by the Fund, and issued and 
       outstanding. DWTFSB shall also provide to the Fund on a regular basis 
       the total number of Shares that are authorized, issued and outstanding 
       and shall notify the Fund in case any proposed issue of Shares by the 
       Fund would result in an overissue. In case any issue of Shares

<PAGE>

       would result in an overissue, DWTFSB shall refuse to issue such Shares 
       and shall not countersign and issue any certificates requested for 
       such Shares. When recording the issuance of Shares, DWTFSB shall have 
       no obligation to take cognizance of any Blue Sky laws relating to the 
       issue of sale of such Shares, which functions shall be the sole 
       responsibility of the Fund.

       agent in connection with dividend reinvestment, accumulation, 
       open-account or similar plans (including without limitation any 
       periodic investment plan or periodic withdrawal program), including 
       but not limited to, maintaining all Shareholder accounts, preparing 
       Shareholder meeting lists, mailing proxies, receiving and tabulating 
       proxies, mailing shareholder reports and prospectuses to current 
       Shareholders, withholding taxes on U.S. resident and non-resident 
       alien accounts, preparing and filing appropriate forms required with 
       respect to dividends and distributions by federal tax authorities for 
       all Shareholders, preparing and mailing confirmation forms and 
       statements of account to Shareholders for all purchases and 
       redemptions of Shares and other confirmable transactions in 
       Shareholder accounts, preparing and mailing activity statements for 
       Shareholders and providing Shareholder account information; 

        (ii) open any and all bank accounts which may be necessary or 
       appropriate in order to provide the foregoing services; and

     (c) In addition, the Fund shall: 

        (i) identify to DWTFSB in writing those transactions and assets to be 
       treated as exempt from Blue Sky reporting for each State; and

       daily purchases and sales for shareholders in each State. The 
       responsibility of DWTFSB for the Fund's status under the securities 
       laws of any State or other jurisdiction is limited to the inclusion on 
       the system of each State as to which the Fund has informed DWTFSB that 
       shares may be sold in compliance with state securities laws and the 
       reporting of purchases and sales in each such State to the Fund as 
       provided above and as agreed from time to time by the Fund and DWTFSB. 

     (d) DWTFSB shall provide such additional services and functions not 
    specifically described herein as may be mutually agreed between DWTFSB and 
    the Fund. Procedures applicable to such services may be established from 
    time to time by agreement between the Fund and DWTFSB. 

Article 2 Fees and Expenses 

   2.1 For performance by DWTFSB pursuant to this Agreement, each Fund agrees 
to pay DWTFSB an annual maintenance fee for each Shareholder account and 
certain transactional fees, if applicable, as set out in the respective fee 
schedule attached hereto as Schedule A. Such fees and out-of-pocket expenses 
and advances identified under Section 2.2 below may be changed from time to 
time subject to mutual written agreement between the Fund and DWTFSB. 

   2.2 In addition to the fees paid under Section 2.1 above, the Fund agrees 
to reimburse DWTFSB for out of pocket expenses in connection with the

reimbursed by the Fund.

consequential damages under any provision of this Agreement or for any act or 
failure to act hereunder. 

   5.6 In order that the indemnification provisions contained in this Article 
5 shall apply, upon the assertion of a claim for which either party may be 
required to indemnify the other, the party seeking indemnification shall 
promptly notify the other party of such assertion, and shall keep the other

        AMENDED AND RESTATED PLAN OF DISTRIBUTION PURSUANT TO RULE 12B-1
                                       OF
                          ACTIVE ASSETS TAX-FREE TRUST

   WHEREAS, Active Assets Tax-Free Trust (the "Fund") is engaged in business 
as an open-end management investment company and is registered as such under 
the Investment Company Act of 1940, as amended (the "Act"); and 

   WHEREAS, on January 4, 1993, the Fund amended and restated a Plan and 
Agreement of Distribution pursuant to Rule 12b-1 under the Act which had 
initially been adopted on March 21, 1983, and the Trustees then determined 
that there was a reasonable likelihood that the Plan of Distribution, as then 
amended and restated, would benefit the Fund and its shareholders; and 

   WHEREAS, the Trustees believe that continuation of said Plan of 
Distribution, as amended and restated herein, is reasonably likely to 
continue to benefit the Fund and its shareholders; and 

   WHEREAS, the Agreement incorporated in said initial Plan and Agreement of 
Distribution was entered into by the Fund with Dean Witter Reynolds Inc. 
("DWR"); and 

   WHEREAS, on January 4, 1993, the Fund and DWR substituted Dean Witter 
Distributors Inc. (the "Distributor") in the place of DWR as distributor of 
the Fund's shares; and 

   WHEREAS, the Fund, DWR and the Distributor intend that DWR will continue 
to promote the sale of Fund shares and provide personal services to Fund 
shareholders with respect to their holdings of Fund shares; and 

   WHEREAS, the Fund and the Distributor have entered into a separate 
Distribution Agreement dated as of May 31, 1997, pursuant to which the Fund 
has employed the Distributor in such capacity during the continuous offering 
of shares of the Fund. 

   NOW, THEREFORE, the Fund hereby amends and restates the Plan of 
Distribution previously adopted and amended and restated, and the Distributor 
hereby agrees to the terms of said Plan of Distribution (the "Plan"), as 
amended and restated herein, in accordance with Rule 12b-1 under the Act on 
the following terms and conditions: 

   1. The Fund is hereby authorized to utilize its assets to finance certain 
activities in connection with the distribution of its shares. 

   2. Subject to the supervision of the Trustees and the terms of the 
Distribution Agreement, the Distributor is authorized to promote the 
distribution of the Fund's shares and to provide related services through 
DWR, its affiliates or other broker-dealers it may select, and its own 
Registered Representatives. The Distributor, DWR, its affiliates and said 
broker-dealers shall be reimbursed, directly or through the Distributor, as 
it may direct, as provided in paragraph 4 hereof for their services and 
expenses, which may include one or more of the following: (1) compensation 
to, and expenses of, account executives and other employees, including 
overhead and telephone expenses; (2) sales incentives and bonuses to sales 
representatives of the Distributor, DWR, its affiliates and other 
broker-dealers, and to marketing personnel in connection with promoting sales 
of shares of the Fund; (3) expenses incurred in connection with promoting 
sales of shares of the Fund; (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. 

   3. The Distributor hereby undertakes to directly bear all costs of 
rendering the services to be performed by it under this Plan and under the 
Distribution Agreement, except for those specific expenses that the Trustees 
determine to reimburse as hereinafter set forth. 

   4. The Fund is hereby authorized to reimburse the Distributor, DWR, its 
affiliates and other broker-dealers for incremental distribution expenses 
incurred by them specifically on behalf of the Fund. Reimbursement will be 
made through payments at the end of each month. The amount of each monthly 
payment may in no event exceed an amount equal to a payment at the annual 
rate of 0.15 of 1% of the Fund's average net assets during the month. In the 
case of all expenses other than expenses representing 

<PAGE>

a residual to account executives, such amounts shall be determined at the 
beginning of each calendar quarter by the Trustees, including a majority of 
the Trustees who are not "interested persons" of the Fund, as defined in the 
Act. Expenses representing a residual to account executives may be reimbursed 
without prior determination. In the event that the Distributor proposes that 
monies shall be reimbursed for other than such expenses, then in making the 
quarterly determinations of the amounts that may be expended by the Fund, the 
Distributor shall provide, and the Trustees shall review, a quarterly budget 
of projected incremental distribution expenses to be incurred by the 
Distributor, DWR, its affiliates or other broker-dealers on behalf of the 
Fund, together with a report explaining the purposes and anticipated benefits 
of incurring such expenses. The Trustees shall determine the particular 
expenses, and the portion thereof, that may be borne by the Fund, and in 
making such determination shall consider the scope of the Distributor's 
commitment to promoting the distribution of the shares of the Fund directly 
or through DWR, its affiliates or other broker-dealers. 

   5. The Distributor may direct that all or any part of the amounts 
receivable by it under this Plan be paid directly to DWR, its affiliates or 
other broker-dealers. 

   6. If, as of the end of any calendar year, the actual expenses incurred by 
the Distributor, DWR, its affiliates and other broker-dealers on behalf of 
the Fund (including accrued expenses and amounts reserved for incentive 
compensation and bonuses) are less than the amount of payments made by the 
Fund pursuant to this Plan, the Distributor shall promptly make appropriate 
reimbursement to the Fund. If, however, as of the end of any calendar year, 
the actual expenses of the Distributor, DWR, its affiliates and other 
broker-dealers are greater than the amount of payments made by the Fund 
pursuant to this Plan, the Fund will not reimburse the Distributor, DWR, its 
affiliates or other broker-dealers for such expenses through payments accrued 
pursuant to this Plan in the subsequent calendar year. 

   7. The Distributor shall provide to the Trustees of the Fund and the 
Trustees shall review, promptly after the end of each calendar quarter, a 
written report regarding the incremental distribution expenses incurred by 
the Distributor, DWR, its affiliates or other broker-dealers on behalf of the 
Fund during such calendar quarter, which report shall include: (1) an 
itemization of the types of expenses and the purposes therefor; (2) the 
amounts of such expenses; and (3) a description of the benefits derived by 
the Fund. 

   8. This Plan, as amended and restated, shall become effective upon 
approval by a vote of the Trustees of the Fund, and of the Trustees who are 
not "interested persons" of the Fund, as defined in the Act, and who have no 
direct or indirect financial interest in the operation of this Plan, cast in 
person at a meeting called for the purpose of voting on this Plan. 

   9. This Plan shall continue in effect until April 30, 1998 and from year 
to year thereafter, provided such continuance is specifically approved at 
least annually in the manner provided for approval of this Plan in paragraph 
8 hereof. This Plan may not be amended to increase materially the amount to 
be spent for the services described herein unless such amendment is approved 
by a vote of at least a majority of the outstanding voting securities of the 
Fund, as defined in the Act, and no material amendment to this Plan shall be 
made unless approved in the manner provided for approval in paragraph 8 
hereof. 

   10. This Plan may be terminated at any time, without the payment of any 
penalty, by vote of a majority of the Trustees who are not "interested 
persons" of the Fund, as defined in the Act, and who have no direct or 
indirect financial interest in the operation of this Plan or by a vote of a 
majority of the outstanding voting securities of the Fund, as defined in the 
Act, on no more than thirty days' written notice to any other party to this
