THE FUND AND ITS MANAGEMENT
- --------------------------------------------------------------------------------
 
   
    Dean  Witter  New  York Municipal  Money  Market  Trust (the  "Fund")  is an
open-end non-diversified management investment  company. The Fund was  organized
as  a trust of  the type commonly  known as a  "Massachusetts business trust" on
December 28,  1989.  Prior  to February  19,  1993,  the Fund's  name  was  Dean
Witter/Sears New York Municipal Money Market 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, which  was incorporated  in  July,
1992,  is a wholly-owned subsidiary  of Dean Witter, Discover  & Co. ("DWDC"), a
balanced financial services organization providing  a broad range of  nationally
marketed credit and investment products.
    
 
   
    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  eighty-one  investment  companies,
twenty-nine of which are  listed on the New  York Stock Exchange, with  combined
total  assets including this Fund of  approximately $69.2 billion as of December
31, 1993. The Investment Manager also manages portfolios of pension plans, other
institutions and individuals which aggregated approximately $2.0 billion at such
date.
    
 
                                       4
<PAGE>
   
    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 expenses of the Fund  assumed by the Investment  Manager, the Fund pays  the
Investment  Manager monthly compensation  calculated daily at  an 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, 1993, the Fund  accrued total compensation to the  Investment
Manager amounting to 0.50% of the Fund's average daily net assets and the Fund's
total expenses amounted to 1.03% 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 and  New  York 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 tax-exempt  Municipal
Obligations  and at least 65% of the Fund's total assets will be invested in New
York Municipal Obligations. The  interest on New  York Municipal Obligations  is
exempt  from Federal, New York  State and New York  City income taxes. Municipal
Obligations other than New  York Municipal Obligations  are exempt from  Federal
tax  but  not from  New York  State and  New York  City taxes.  However, certain
Municipal Obligations in  which the Fund  may invest without  limit may  subject
certain  investors to the alternative minimum  tax and, therefore, a substantial
portion of the income  produced by the  Fund may be  taxable for such  investors
under  the alternative minimum tax. The Fund, therefore, may not ordinarily be a
suitable investment for  investors who  are subject to  the alternative  minimum
tax.  The  suitability  of the  Fund  for  these investors  will  depend  upon a
comparison of  the  after-tax yield  likely  to be  provided  from the  Fund  to
comparable tax-exempt investments not subject to such tax and also to comparable
fully  taxable investments  in light of  each such investor's  tax position. See
"Taxation." 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 in high
quality tax-exempt securities with  short-term maturities (remaining  maturities
of  thirteen months or  less) as follows.  Such securities will  include (i) New
York Municipal Bonds, New York Municipal Notes and New York Municipal Commercial
Paper, 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
Trustees.
 
    Up to 35% of the  Fund's total assets may  be invested in securities  exempt
from  federal income tax  but not from New  York State and  New York City income
taxes ("non-New York tax-exempt
 
                                       5
<PAGE>
securities") and 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 and  more than  35% of its  total assets in
non-New York tax-exempt securities  to maintain a  "defensive" posture when,  in
the opinion of the Investment Manager, prevailing market or financial conditions
so  warrant. 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.
 
    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 or S&P rating of AAA. An obligation shall be considered  a
New  York  Municipal  Bond,  New  York  Municipal  Note  or  New  York Municipal
Commercial Paper only if, in the  opinion of bond counsel, the interest  payable
therefrom  is exempt from both  federal income tax and  New York personal income
tax.
 
    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 or  other changes  in
total  assets  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
 
                                       6
<PAGE>
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 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.
 
    Lease  obligations represent a relatively new type of financing that has not
yet developed  the  depth of  marketability  associated with  more  conventional
municipal  obligations, and, as a result,  certain of such lease obligations may
be considered illiquid  securities. To determine  whether 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 is classified as a non-diversified investment company under the Act
and as such is not limited  by the Act in the  proportion of its assets that  it
may  invest in the obligations of a  single issuer. However, the Fund intends to
conduct its operations  so as  to qualify  as a  "regulated investment  company"
under Subchapter M of the Internal Revenue Code (the "Code"). See "Taxation." In
order  to qualify, among other requirements, the Fund will limit its investments
so that at the close of each quarter of the taxable year, (i) not more than  25%
of  the  market  value  of the  Fund's  total  assets will  be  invested  in the
securities of a single issuer, and (ii) with respect to 50% of the market  value
of  its total assets  not more than 5%  will be invested in  the securities of a
single issuer and the Fund will not own more than 10% of the outstanding  voting
securities  of a single issuer. To the  extent that a relatively high percentage
of the Fund's assets may be invested  in the obligations of a limited number  of
issuers,  the Fund's portfolio securities will be more susceptible to any single
economic, political or regulatory occurrence than the portfolio securities of  a
diversified investment company. Additionally, the Fund's yield will fluctuate to
a  greater extent than that  of a diversified investment  company as a result of
changes in the financial condition or in the market's assessment of the  various
issuers.  The  limitations  described  in  this  paragraph  are  not fundamental
policies and  may  be  revised  to the  extent  applicable  Federal  income  tax
requirements are revised.
 
                                       7
<PAGE>
    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  disposition 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 sale 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 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 DWR.
In addition, the Fund may incur brokerage commissions on transactions  conducted
through DWR.
 
SPECIAL CONSIDERATIONS RELATING TO NEW YORK TAX-EXEMPT SECURITIES
 
    Since   the  Fund  concentrates  its  investments  in  New  York  tax-exempt
securities, the  Fund  is affected  by  any political,  economic  or  regulatory
developments  affecting  the  ability  of New  York  tax-exempt  issuers  to pay
interest or repay principal. Investors should  be aware that certain issuers  of
New  York tax-exempt securities have  experienced serious financial difficulties
in recent years. A reoccurrence of these difficulties may impair the ability  of
certain New York issuers to maintain debt service on their obligations.
 
    The fiscal stability of New York State is related to the fiscal stability of
the  State's  municipalities,  its  Agencies  and  Authorities  (which generally
finance, construct  and operate  revenue-producing public  benefit  facilities).
This is due in part to the fact that Agencies, Authorities and local governments
in  financial trouble often seek State  financial assistance. The experience has
been that if New
 
                                       8
<PAGE>
York City  or any  of  the Agencies  or  Authorities suffers  serious  financial
difficulty,  both the ability of the State, New York City, the State's political
subdivisions, the Agencies and the Authorities to obtain financing in the public
credit  markets  and  the  market  price  of  outstanding  New  York  tax-exempt
securities are adversely affected.
 
    For  a  more detailed  discussion  of the  risks  of investing  in  New York
tax-exempt securities, see the Statement of Additional Information.
 
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 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 assets
does not require elimination of any security from the portfolio.
 
    The Fund may not:
        1.  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.
 
        2.   Invest  25% or  more 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 Municipal Obligations,
    including  those  issued  by  the  State  of  New  York  or  its   political
    subdivisions, or to domestic bank obligations.
 
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 of the shares  will be at their  net asset value next determined
(see "Determination of Net Asset Value" below) after receipt of a purchase order
and acceptance by  Dean Witter Trust  Company (the "Transfer  Agent") 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  directly to  Dean  Witter Trust
Company, at  P.O. Box  1040, Jersey  City,  N.J. 07303.  Checks should  be  made
payable  to the Dean  Witter New York  Municipal Money Market  Trust and sent to
Dean Witter  Trust Company  at the  above  address. Purchases  by wire  must  be

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 noon  New York  time are normally
effective that day and wire purchases received  after 12 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. The Fund will waive the minimum
initial investment for the automatic reinvestment of distributions from  certain
unit  investment  trusts. The  Fund reserves  the right  to reject  any purchase
order.
    
 
   
    Orders for the purchase  of Fund shares placed  by customers through DWR  or
other  Selected  Broker-Dealers 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 other Selected
Broker-Dealers.  Investors desiring  same day effectiveness  should wire Federal
Funds directly  to the  Transfer Agent.  An order  procedure 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 other Selected Broker-Dealer's will not have any of
such funds invested in the Fund until the business day after the customer places
an order with  DWR or other  Selected Broker-Dealers 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  the Fund's shares  are reimbursed. The
principal activities and services which may  be provided by 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
    
 
                                       10
<PAGE>
   
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, 1993, 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 4:00 p.m. New
York time on each  day that the New  York Stock Exchange is  open 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  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-TM-.    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 next business day  after
the transfer of funds is effected.
    
 
   
    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  various Dean  Witter  Funds which  are  open-end investment
companies sold with either a front-end (at time of purchase) sales charge ("FESC
funds") or a contingent deferred sales charge ("CDSC funds"), may be redeemed at
their next calculated  net asset value  and the proceeds  of the redemption  are
used  to purchase shares of  five money market funds  and Dean Witter Short-Term
U.S. Treasury Trust, Dean  Witter Limited Term Municipal  Trust and Dean  Witter
Short-Term Bond Fund (the foregoing eight non-FESC or CDSC funds are hereinafter
collectively  referred  to  in  this  section  as  the  "Exchange  Funds"). When
exchanging into a money market fund from an FESC fund or a CDSC fund, shares  of
the  FESC fund or the CDSC fund are  redeemed at their next calculated net asset
value and exchanged for shares of the money market
    
 
                                       11
<PAGE>
   
fund at their net asset value determined the following business day. An exchange
from an FESC fund or a CDSC fund 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.  Subsequently,  shares  of  these
Exchange Funds received in an exchange for shares of an FESC fund (regardless of
the  type of fund originally purchased) may be redeemed and exchanged for shares
of the Exchange Funds, FESC funds or CDSC funds (however, shares of CDSC  funds,
including  shares acquired  in exchange  for (i)  shares of  FESC funds  or (ii)
shares of the Exchange Funds which were acquired in exchange for shares of  FESC
funds,  may not be exchanged for shares  of FESC funds). Additionally, shares of
the money  market funds  received  in an  exchange for  shares  of a  CDSC  fund
(regardless  of  the type  of  fund originally  purchased)  may be  redeemed and
exchanged for  shares of  the  Exchange Funds  or  CDSC funds.  Ultimately,  any
applicable  contingent deferred sales charge ("CDSC")  will have to be paid upon
redemption of shares originally  purchased from a CDSC  fund. (If shares of  the
Exchange  Funds received in exchange for shares originally purchased from a CDSC
fund are  exchanged for  shares of  another CDSC  fund having  a different  CDSC
schedule than that of the CDSC fund from which the Exchange Funds were acquired,
the  shares will be subject  to the higher CDSC  schedule.) During the period of
time the shares  originally purchased from  a CDSC fund  remain in the  Exchange
Funds,  the holding period (for the purpose of determining the rate of the CDSC)
is frozen so that the  charge is based upon the  period of time the  shareholder
actually  held shares of a  CDSC fund. However, 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 incurred on or after that date which are attributable to those shares  (see
"Plan  of Distribution").  Exchanges involving FESC  funds or CDSC  funds may be
made after the shares of the FESC fund or CDSC fund acquired by purchase (not by
exchange or dividend reinvestment) have been  held for thirty days. There is  no
waiting  period  for  exchanges  of  shares  acquired  by  exchange  or dividend
reinvestment.
    
 
   
    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.
    
 
    Purchases  and  exchanges should  be made  for  investment purposes  only. A
pattern of frequent  exchanges may  be deemed by  the Investment  Manager to  be
abusive and contrary to the best interests of the Fund's other shareholders and,
at  the Investment Manager's discretion, may be limited by the Fund's refusal to
accept additional purchases  and/or exchanges  from the  investor. Although  the
Fund  does not  have any  specific definition of  what constitutes  a pattern of
frequent exchanges,  and  will  consider all  relevant  factors  in  determining
whether  a particular situation is abusive and contrary to the best interests of
the Fund and its other shareholders, investors should be aware that the Fund and
each of the other Dean Witter Funds  may in their discretion limit or  otherwise
restrict  the number of  times this Exchange  Privilege may be  exercised by any
investor. Any such restriction will be made  by the Fund on a prospective  basis
only,  upon notice  to the  shareholder not later  than ten  days following such
shareholder's most recent exchange.
 
   
    The Exchange Privilege may be terminated or revised at any time by the  Fund
and/or  any  of such  Dean Witter  Funds for  which  shares of  the Fund  may be
exchanged, upon  such  notice  as  may  be  required  by  applicable  regulatory
agencies.  Shareholders maintaining margin  accounts with DWR  or other Selected
Broker-Dealers are referred to their account executive regarding restrictions on
exchange of shares of the Fund pledged in the margin account.
    
 
                                       12
<PAGE>
   
    The current prospectus for each  fund describes its investment  objective(s)
and  policies, and shareholders  should obtain one and  read it carefully before
investing. Exchanges are subject to  the minimum investment requirement and  any
other  conditions imposed by each fund. An  exchange will be treated for federal
income tax purposes the same  as a repurchase or  redemption of shares on  which
the  shareholder has realized  a capital gain  or loss. However,  the ability to
deduct capital losses on an exchange may be limited in situations where there is
an exchange of  shares within ninety  days after the  shares are purchased.  The
Exchange  Privilege is only available in states where an exchange may legally be
made.
    
   
    If DWR or another Selected Broker-Dealer is the current dealer of record and
its account  numbers  are part  of  the account  information,  shareholders  may
initiate  an exchange of shares of the Fund for shares of any of the Dean Witter
Funds (for which the Exchange Privilege is available) pursuant to this  Exchange
Privilege  by  contacting  their  DWR or  other  Selected  Broker-Dealer account
executive  (no  Exchange  Privilege  Authorization  Form  is  required).   Other
shareholders (and those shareholders who are DWR or other Selected Broker-Dealer
clients  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) 526-3143  (toll
free).  The  Fund will  employ reasonable  procedures  to confirm  that exchange
instructions communicated over  the telephone are  genuine. Such procedures  may
include requiring various forms of personal identification such as name, mailing
address,  social security  or other tax  identification number and  DWR or other
Selected Broker-Dealer account number (if any). Telephone instructions may  also
be recorded. If such procedures are not employed, the Fund may be liable for any
losses  due  to  unauthorized  or  fraudulent  instructions.  Telephone exchange
instructions will be  accepted if received  by the Transfer  Agent between  9:00
a.m.  and 4:00 p.m.  New York time,  on any day  the New York  Stock Exchange is
open. Any shareholder wishing  to make an exchange  who has previously filed  an
Exchange  Privilege Authorization Form  and who is  unable to reach  the Fund by
telephone should contact his or her DWR or other Selected Broker-Dealer  account
executive,  if appropriate, or make a written exchange request. Shareholders are
advised that  during  periods of  drastic  economic  or market  changes,  it  is
possible  that the telephone exchange procedures  may be difficult to implement,
although this has not been the experience of the Dean Witter Funds in the past.
    
 
   
    For further information regarding the Exchange Privilege shareholders should
contact their  DWR or  other  Selected Broker-Dealer  account executive  or  the
Transfer Agent.

REDEMPTION AND REPURCHASE 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  Fund's transfer
agent, Dean Witter Trust Company (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
specifically specified on an Investment Application that all owners are required
to sign checks. Only shareholders having accounts in which no share certificates
have been issued will be permitted to redeem shares by check.
    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 government,  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 Transfer 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  shareholder's name  and account
number and be wired or called to the Transfer Agent:
 
   
    -- 800-526-3143 (Toll Free)
    -- Telex No. 125076
    
 
3. BY MAIL
 
    A shareholder may  redeem shares by  sending a letter  to Dean Witter  Trust
Company,  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 contingent  deferred
sales  charge will be imposed upon the  redemption of such shares (see "Purchase
of Fund Shares--Exchange Privilege").
 
    If shares to be redeemed are represented by a share certificate, the request
for redemption  must  be  accompanied  by the  share  certificate  and  a  share
assignment  form signed by the registered  shareholder[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 Fund's Transfer Agent. Signatures must  be
guaranteed  by an eligible  guarantor. 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 Company,  P.O. Box 983, Jersey
City, NJ 07303.
 
    Generally, the Fund  will attempt to  make payment for  all redemptions  and
repurchases 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 or repurchased were purchased by  check (including a certified or  bank
cashier's  check), payment may be delayed for  the minimum time needed to verify
that the check used for investment has been honored (not more than fifteen  days
from  the time of receipt of the check  by the Transfer Agent). In addition, the
Fund may  postpone  redemptions or  repurchases  at certain  times  when  normal
trading is not taking place on the New York Stock Exchange.
 
   
    The  Fund reserves  the right, on  60 days'  notice, to redeem  at their 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 it  by a shareholder maintaining a brokerage
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
another   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  other 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    other    Selected
    
 
                                       15
<PAGE>
   
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.
    
 
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. 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 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 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-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 total assets in tax-exempt securities. If
the  Fund satisfies  such requirement, dividends  from net  investment income to
shareholders, whether taken  in cash  or reinvested in  additional Fund  shares,
will  be excludable  from gross  income for federal  income tax  purposes to the
extent net interest income is represented by interest on tax-exempt  securities.
Exempt-interest dividends are included, however, in determining what portion, if
any, of a person's Social Security benefits are subject to federal income tax.
 
    The   Code  subjects  interest  received  on  certain  otherwise  tax-exempt
securities to an alternative minimum  tax. This alternative minimum tax  applies
to interest received on "private activity bonds" (in general, bonds that benefit
non-government 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. The  Fund may invest without
limit in  such "private  activity bonds,"  with the  result that  a  substantial
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
 
situa-
                                       16
<PAGE>
tions  where  the  "adjusted current  earnings  of the  corporation  exceeds its
alternative minimum taxable income.
 
   
    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 constitutes an item of  tax preference. (Unlike federal law,  no
portion  of  the  exempt-interest  dividends  will  constitute  an  item  of tax
preference for New York personal income tax purposes.) 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.
    
 
    To  the  extent  that  dividends  are  derived  from  interest  on  New York
tax-exempt securities, such dividends  will also be exempt  from New York  State
and  New York City personal income  taxes. Shareholders will normally be subject
to federal and New York State and New York City personal income tax on dividends
paid from interest income derived  from taxable securities and on  distributions
of net capital gains. For federal and New York State or New York City income tax
purposes,  distributions of net long-term capital  gains, if any, are taxable to
shareholders as long-term capital gains, regardless of how long the  shareholder
has  held the Fund shares and regardless of whether the distribution is received
in additional  shares  or in  cash.  To avoid  being  subject to  a  31%  backup
withholding  tax on  taxable dividends and  capital gains  distributions and the
proceeds of redemptions and  repurchases, shareholders' taxpayer  identification
numbers must be furnished and certified as to accuracy.
    Interest  on  indebtedness incurred  by shareholders  or related  parties to
purchase or  carry  shares  of  an  investment  company  paying  exempt-interest
dividends,  such as the Fund, will not be deductible by the investor for federal
or New York State or New York City personal income tax purposes.
 
    The foregoing relates to federal income  taxation and to New York State  and
New  York City  personal income  taxation as in  effect as  of the  date of this
Prospectus.
 
    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 stated in the  advertisement). This income is then "annualized."
That is, the amount of income generated by the 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 of personal liability is remote.
    
 
    SHAREHOLDER INQUIRIES.  All inquiries regarding the Fund should be  directed
to  the Fund or  the Transfer Agent  at one of  its telephone numbers  or at its
address, as are set forth on the front cover of this Prospectus.

DEAN WITTER NEW YORK MUNICIPAL MONEY MARKET TRUST
REPORT OF INDEPENDENT ACCOUNTANTS
    
- --------------------------------------------------------------------------------
 
   
To the Shareholders and Trustees of Dean Witter New York Municipal Money Market
Trust
    
 
   
In  our opinion, the accompanying statement of assets and liabilities, including
the portfolio of investments,  and the related statements  of operations and  of
changes  in net assets and the financial highlights (appearing in the "Financial
Highlights" table on page 4 of this Prospectus) present fairly, in all  material
respects,  the financial position of Dean Witter New York Municipal Money Market
Trust (the "Fund") at December 31, 1993,  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 three years  in
the  period  then ended  and  for the  period  March 20,  1990  (commencement of
operations) through December  31, 1990,  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 owned at December 31, 1993 by correspondence with the
custodian, provide a reasonable basis for the opinion expressed above.

Market  Trust (the  "Fund") is  registered under  the Investment  Company Act of
1940,  as  amended  (the  "Act"),  as  a  non-diversified,  open-end  management
investment  company. It  was organized on  December 28, 1989  as a Massachusetts
business trust and the Fund commenced operations on March 20, 1990. On  February

Money Market Trust to Dean Witter New York Municipal Money Market Trust.
    
 
    The following is a summary of the 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). In computing net
    investment income,  the  Fund  amortizes any  premiums  and  original  issue
    discounts  and accrues interest  income daily on  securities owned. Realized
    gains and losses on security  transactions are determined on the  identified
    cost method.
 
    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 non-taxable income to its
    shareholders. Accordingly, no federal income tax provision is required.
 
    D.  DIVIDENDS   AND  DISTRIBUTIONS   TO   SHAREHOLDERS  --   Dividends   and
    distributions  to shareholders are recorded  by the Fund as  of the close of
    the Fund's business day.
 
    E.  ORGANIZATIONAL   EXPENSES  --   The  Fund's   Investment  Manager   paid
    organizational  expenses of the Fund in the amount of approximately $58,000.
    The Fund reimbursed the Investment  Manager for these costs. These  expenses
    are  being amortized by the Fund on a  straight line basis over a period not
    to exceed five years from the commencement of operations.
 
   
2.   INVESTMENT MANAGEMENT  AGREEMENT --  Pursuant to  an Investment  Management
Agreement  (the "Agreement") with Dean Witter InterCapital Inc. (the "Investment
Manager"), the  Fund pays  its Investment  Manager a  management fee  calculated
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% 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

billion but not exceeding $3 billion; and 0.25% of 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 office space and 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.

distributed by Dean Witter Distributors  Inc. (the "Distributor"), an  affiliate
of  the Investment  Manager. The  Fund has entered  into a  Plan of Distribution

THE FUND AND ITS MANAGEMENT
- --------------------------------------------------------------------------------
 
THE FUND
 
    The  Fund is a Trust of the type commonly known as a "Massachusetts business
trust" and was organized under the laws of the Commonwealth of Massachusetts  on
December  28, 1989.  On February 19,  1993, the  Fund's name was  changed to its
current name Dean  Witter New York  Money Market Trust.  The Trust was  formerly
known as Dean Witter/Sears New York Municipal Money Market Trust.
 
THE INVESTMENT MANAGER
 
   
    Dean  Witter InterCapital Inc. ("InterCapital" or the "Investment Manager"),
a Delaware corporation, 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 Dean Witter Discover & Co. ("DWDC"), a Delaware corporation. In an
internal reorganization which took place in January, 1993, InterCapital  assumed
the  investment  advisory, administrative  and management  activities previously

of Additional  Information, the  terms "InterCapital"  and "Investment  Manager"

conducted by  or  under  the direction  of  officers  of the  Fund  and  of  the
Investment  Manager, subject  to review  of investments  by the  Fund's Board of
Trustees. In addition, Trustees of the Fund provide guidance on economic factors
and interest  rate trends.  Information as  to these  Trustees and  Officers  is

closed-end Investment companies.
    
 
    The Investment Manager also serves as an investment adviser for Dean  Witter
World  Wide Investment Fund,  an investment company organized  under the laws of
Luxembourg, shares of which are not available for purchase in the United  States
or by American citizens outside 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.
 
    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, 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, statements of additional information, 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.
 
   
    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. The  foregoing
internal  reorganization 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
will  be paid by the Fund.  The expenses borne by the  Fund 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,
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 and Statements of
Additional Information  of  the  Fund  and supplements  thereto  to  the  Fund's
shareholders;  all  expenses  of  shareholders' and  trustees'  meetings  and of
preparing, printing and mailing of proxy statements and reports to shareholders;
fees and  travel  expenses of  Trustees  or members  of  any advisory  board  or
committee  who  are not  employees of  the Investment  Manager or  any corporate
affiliate of  the Investment  Manager; all  expenses incident  to any  dividend,
withdrawal  or redemption options;  charges and expenses  of any outside service
used for  pricing of  the Fund's  shares; fees  and expenses  of legal  counsel,
including  counsel to the Trustees who are not interested persons of the Fund or
of the Investment Manager (not  including compensation or expenses of  attorneys
who  are  employees  of  the Investment  Manager)  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.

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.
The Investment  Manager assumed  all expenses  (except for  brokerage and  12b-1
fees)  and waived the compensation provided for  in the Agreement for the period
March 20, 1990 (commencement of operations  through December 31, 1990). For  the
fiscal  years ended December 31, 1991, December  31, 1992 and December 31, 1993,
the Fund  accrued to  the  Investment Manager  total compensation  of  $444,111,
$272,459 and $225,305, respectively.
    
 
   
    Pursuant  to the Agreement, total operating expenses of the Fund are subject
to applicable limitations under rules and  regulations of states where the  Fund
is  authorized to sell its shares. Therefore, operating expenses are effectively
subject to the most restrictive of such  limitations as the same may be  amended
from time to time. Presently, the most restrictive limitation is as follows: if,
in  any  fiscal  year,  the  Fund's  total  operating  expenses,  including  the
investment management fee and  the compensation paid  to the Investment  Manager
pursuant  to  the  Plan  and  Agreement  of  Distribution  described  below, and
exclusive of taxes, interest, brokerage fees and extraordinary expenses (to  the
extent  permitted by applicable  state securities laws  and regulations), exceed
2 1/2% of  the first $30,000,000  of average daily  net assets, 2%  of the  next
$70,000,000  and 1 1/2% of any  excess over $100,000,000, the Investment Manager
will reimburse the Fund for the amount of such excess. Such amount, if any, will
be calculated daily  and credited on  a monthly basis.  During the fiscal  years
ended  December 31, 1991,  December 31, 1992  and December 31,  1993, the Fund's
expenses did not exceed such limitation.
    
 
    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 Investment  Manager has  paid the  organizational expenses  of the  Fund
incurred prior to the offering of the Fund's shares. The Fund has reimbursed the
Investment  Manager in an amount of approximately $58,000 for such expenses. The
Fund has deferred and is amortizing the reimbursed expenses on the straight line
method over a period not to exceed  five years from the date of commencement  of
the Fund's operations.
 
   
    The Agreement was initially approved by the Trustees on October 22, 1992 and
by  the  shareholders  on  January  12,  1993.  The  Agreement  is substantially
identical to  a  prior  investment  management  agreement  which  was  initially
approved  by  the  Trustees  on February  15,  1990,  by DWR  as  the  then sole
shareholder on February 16, 1990 and by the Shareholders at a Special Meeting of
Shareholders held on June 20, 1991.
    
 
   
    The Agreement took  effect on  June 30, 1993,  upon the  spin-off by  Sears,
Roebuck and Co. of its remaining shares of DWDC. 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. The  Agreement will automatically  terminate in  the
event of its assignment (as defined in the Act).
    
 
   
    Under its terms, the Agreement continues in effect until April 30, 1994, and
will  continue  from  year  to  year  thereafter,  provided  continuance  of the
Agreement   is   approved   at   least    annually   by   the   vote   of    the
    
 
                                       5
<PAGE>
   
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  as "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 terms  of the  new Agreement  are substantially  identical in all
material respects to  those of  the present Agreement,  except for  the date  of
effectiveness and initial termination.
    
 
   
    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 investment management  contract between InterCapital and the  Fund
is terminated, or if the affiliation between InterCapital and its parent company
is  terminated, the Fund will eliminate the  name "Dean Witter" from its name if
DWR or its parent company shall so request.

    The Fund pays each Trustee who is  not an employee, or retired employee,  of
the  Investment Manager or an affiliated company an annual fee of $1,200 ($1,600
prior to December 31, 1993) plus $50 for each meeting of the Board of  Trustees,
the Audit Committee or the Committee of the Independent Trustees attended by the
Trustee  in  person  (the Fund  pays  the  Chairman of  the  Audit  Committee an
additional annual fee of $1,000 ($1,200 prior to December 31, 1993) and pays the
Chairman of the Committee of the  Independent Trustees an additional annual  fee
of  $2,400, in each case inclusive of the Committee meeting fees). 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 employed by the Investment Manager or an affiliated company thereof
receive  no compensation  or expense reimbursement  from the Fund.  The Fund has
adopted a  retirement program  under which  an Independent  Trustee who  retires
after  a  minimum required  period of  service would  be entitled  to retirement
payments upon reaching the eligible  retirement date (normally, after  attaining
age  72) based upon length of service  and computed as a percentage of one-fifth
of the total compensation earned by such Trustee for service to the Fund in  the
five-year  period prior to the date  of the Trustee's retirement. No Independent
Trustee has retired since  the adoption of  the program and  no payments by  the
Fund  have been made under it. For the  fiscal year ended December 31, 1993, the
Fund accrued a  total of  $33,631 for Trustees  fees and  expenses and  benefits
under  the retirement program.  As of the  date of this  Statement of Additional
Information, the aggregate shares of the  Fund owned by the Fund's officers  and
Trustees as a group was less than 1 percent of the Fund's shares outstanding.
    
 
INVESTMENT PRACTICES AND POLICIES
- --------------------------------------------------------------------------------
 
PORTFOLIO SECURITIES
 
    TAXABLE  SECURITIES.  As discussed in the Prospectus, the Fund may invest up
to 20% of its  total assets in taxable  money market instruments and  repurchase
agreements.  Investments in taxable money  market instruments would generally be
made under  any  one of  the  following circumstances:  (a)  pending  investment
proceeds  of  sale  of  Fund  shares or  of  portfolio  securities;  (b) pending
settlement of purchases of portfolio  securities; and (c) to maintain  liquidity
for  the purpose  of meeting  anticipated redemptions.  Only those  non-New York
tax-exempt securities  which  satisfy the  standards  established for  New  York
tax-exempt  securities may be purchased by the  Fund. The types of taxable money
market instruments in  which the Fund  may 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, its  agencies,
instrumentalities  or authorities;  (ii) commercial  paper rated  P-1 by Moody's
Investors Services, Inc.  ("Moody's") or  A-1 by Standard  & Poor's  Corporation
("S&P");  (iii)  certificates of  deposit of  domestic banks  with assets  of $1
billion or  more;  and (iv)  repurchase  agreements with  respect  to  portfolio
securities.  In addition, the Fund  may temporarily invest more  than 20% of its
total assets  in taxable  money  market instruments  to maintain  a  "defensive"
posture when, in the opinion of the Investment Manager, it is advisable to do so
because of market conditions.
 
    TAX-EXEMPT  SECURITIES.  As discussed in the Prospectus, at least 80% of the
Fund's total assets will be invested  in Municipal Obligations and at least  65%
of  the Fund's total assets will be  invested in New York Municipal Obligations.
(New York  Municipal Bonds,  New York  Municipal Notes  and New  York  Municipal
Commercial  Paper). Such New York Municipal Obligations are exempt from Federal,
New York State and New  York City income tax except  to those investors who  are
subject  to the alternative minimum  tax. Up to 35%  of the Trust's total assets
may  be  invested  in  Municipal  Obligations  other  than  New  York  Municipal
Obligations.  Such Municipal Obligations are exempt from Federal income tax (but
not New York State and New York City income taxes) except to those investors who
are subject to  the alternative minimum  tax. The Trust  may temporarily  invest
more than 35% of its total assets in non-New York Municipal Obligations in order
to  maintain a defensive posture when, in the opinion of the Investment Manager,
prevailing market or financial conditions so  warrant. In regard to the  Moody's
and S&P ratings discussed in the Prospectus, it should be noted that the ratings
represent  the organizations' opinions as to the quality of the securities which
they undertake to rate and the ratings are general and not absolute standards of
quality. For  a description  of  Municipal Bond,  Municipal Note  and  Municipal
Commercial  Paper ratings by Moody's and S&P, see the Appendix to this Statement
of Additional Information.
 
                                       9
<PAGE>
    The  percentage and rating limitations discussed above and in the Prospectus
apply at the  time of acquisition  of a  security based upon  the last  previous
determination  of  the Fund's  net  asset value;  any  subsequent change  in any
ratings by  a rating  service or  change in  percentages resulting  from  market
fluctuations  or other changes  in total assets will  not require elimination of
any security from the Fund's portfolio.
 
    The payment  of  principal and  interest  by issuers  of  certain  Municipal
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 a  Municipal Obligation
meets the Fund's investment quality  requirements. In addition, some issues  may
contain  provisions which permit the Fund to demand from the issuer repayment of
principal at some specified period(s) prior to maturity.
 
    MUNICIPAL BONDS.   Municipal Bonds, as  referred to in  the Prospectus,  are
debt  obligations of a state, its  cities, municipalities and municipal agencies
(all of which  are generally  referred to as  "municipalities") which  generally
have  a maturity at the time of issue of one year or more, and the interest from
which is, in the  opinion of bond  counsel, exempt from  federal income tax.  In
addition  to these requirements, the interest from New York Municipal Bonds must
be, in the opinion of  bond counsel, exempt from  New York personal income  tax.
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. In addition to those requirements,  the
interest  from New York Municipal Notes must be, in the opinion of bond counsel,
exempt from New York personal 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
Government.
 
    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. In addition to those requirements,  the
interest from New York Commercial Paper must be, in the opinion of bond counsel,
exempt  from New York personal income tax. It may be issued at a discount and is
sometimes referred to as Short-Term  Discount Notes. Municipal Commercial  Paper
is likely to be used to meet seasonal working capital needs of a municipality or
interim  construction  financing and  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, 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
 
                                       10
<PAGE>
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 with  respect to  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.
 
    Issuers  of these obligations  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 any state extending the  time for payment of principal or  interest,
or  both, or imposing 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
issuers  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 should enhance the ability of the Fund to maintain a stable net
asset value per  share (see "How  Net Asset  Value is Determined")  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 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 liquid assets such as cash, U.S. government securities
or other appropriate high grade debt  obligations 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.
 
    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
 
                                       11
<PAGE>
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 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. In addition, the value of the
collateral underlying the repurchase agreement will always be at least equal  to
the  repurchase price, including  any accrued interest  earned on the repurchase
agreement. Such collateral  will consist of  Government Securities or  "Eligible
Securities"  (as  described below  under  the caption  "How  Net Asset  Value is
Determined") rated in the highest  grade by a nationally recognized  statistical
rating  organization (an "NRSRO") whose  ratings qualify the collateral security
as an Eligible Security. 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 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. During the fiscal year ended
December 31, 1993,  the Fund did  not enter into  any repurchase agreements  and
does  not intend to enter into  any repurchase agreements during the foreseeable
future.
    
 
    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,  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  and  New York  personal  income  tax, while
preserving the necessary flexibility and  liquidity to purchase securities on  a
when-issued  basis, 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 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
 
                                       12
<PAGE>
   
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. The Fund may not invest  more than 10% of its total assets in
puts at any given time. During the fiscal year ended December 31, 1993, the Fund
did not purchase any put  options and the Fund does  not intend to purchase  put
options in the foreseeable future.
    
 
    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 that  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 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  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 a security issued by the guarantor if the value  of
all securities 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 term "bank obligations"  as referred to in  Investment Restriction 3  in
the  Prospectus  refers  to short-term  obligations  (including  certificates of
deposit and bankers'  acceptances) of banks  subject to regulation  by the  U.S.
Government  and  having total  assets  of $1  billion  or more,  and instruments
secured by such obligations,  not including obligations  of foreign branches  of
domestic banks.
 
                                       13
<PAGE>
    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 or the
    Investment Manager  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 a 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)
    purchasing any securities on a when-issued or delayed delivery basis; or (b)
    borrowing money in accordance with restrictions described above.
 
        11. Make short sales of securities.
 
        12.  Purchase securities on margin, except  for such short-term loans as
    are necessary for the clearance of purchases of portfolio securities.
 
        13. 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.
 
        14.  Invest for the  purpose of exercising control  or management of any
    other issuer.
 
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
 
                                       14
<PAGE>
   
market instruments directly  from an  issuer, in  which case  no commissions  or
discounts  are paid. During  the fiscal years ended  December 31, 1991, December
31, 1992 and December 31, 1993, the  Fund paid no such brokerage commissions  or
concessions.
    
 
    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,  the main
factors considered are 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.
 
    The policy of the Fund, regarding purchases and sales of securities for  its
portfolio,  is  that  primary  consideration  be  given  to  obtaining  the most
favorable  prices  and  efficient  execution  of  transactions.  In  seeking  to
implement  the Fund's policies, the Investment Manager effects transactions with
those brokers and dealers who the  Investment Manager believes provide the  most
favorable  prices  and are  capable of  providing  efficient executions.  If the
Investment Manager believes such price  and executions are obtainable from  more
than  one  broker or  dealer,  it may  give  consideration to  placing portfolio
transactions with those brokers and dealers who also furnish research and  other
services  to the Fund or the Investment  Manager. 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.
 
    The information and services received by the Investment Manager from brokers
and  dealers may be  of benefit to  the Investment Manager  in the management of
accounts of some of its other clients and may not in all cases benefit the  Fund
directly.  While  the receipt  of  such information  and  services is  useful in
varying degrees and would  generally reduce the amount  of research or  services
otherwise  performed by the Investment Manager  and thereby reduce its expenses,
it is of indeterminable value and the Fund does not reduce the management fee it
pays to the Investment  Manager by any  amount that may  be attributable to  the
value of such services.
 
   
    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, 1991, 1992 and 1993, the Fund did not effect any
principal transactions 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. In order for DWR to effect portfolio transactions for  the
Fund,  the  commissions, fees  or  other remuneration  received  by DWR  must be
reasonable and fair compared to the commissions, fees or other remuneration paid
to other brokers  in connection with  comparable transactions involving  similar
securities  being purchased or sold on an exchange during a comparable period of
time. This standard  would allow DWR  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  DWR are
consistent with the foregoing standard.  During the fiscal years ended  December
31, 1991, 1992, and 1993, the Fund paid no brokerage commissions to DWR.
    
 
    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-
 
                                       15
<PAGE>
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 calculate 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.
 
   
SPECIAL CONSIDERATIONS RELATING TO NEW YORK TAX-EXEMPT SECURITIES
    
 
   
    During the mid-1970's, New York State  (the "State"), some of its  agencies,
instrumentalities  and  public  benefit  corporations  (the  "Authorities"), and
certain of its municipalities faced  serious financial difficulties. To  address
many  of these financial problems, the State developed various programs, many of
which  were  successful  in  ameliorating  the  financial  crisis.  Any  further
financial problems experienced by these Authorities or municipalities could have
a  direct adverse effect on the New York Municipal Obligations in which the Fund
invests.
    
 
   
NEW YORK CITY
    
 
   
    GENERAL.  More than  any other municipality, the  fiscal health of New  York
City  (the "City") has a  significant effect on the  fiscal health of the State.
Over the past three years,  the rate of economic growth  in the City has  slowed
substantially.  During  the 1990  and 1991  fiscal  years, the  City experienced
significant shortfalls in almost all of  its major tax sources and increases  in
services  costs.  Beginning in  1992, the  improvement  in the  national economy
helped stabilize conditions in the City. The City now projects, and its  current
four-year  financial  plan assumes,  that the  City's  economy will  continue to
improve during calendar  year 1993 and  that a modest  employment recovery  will
begin during the second half of the 1993 calendar year.
    
 
   
    For  each of the 1981 through 1992  fiscal years, the City achieved balanced
operating results as reported in  accordance with generally accepted  accounting
principles  ("GAAP") and the City's 1993 fiscal year results are projected to be
balanced in accordance  with GAAP. The  City was required  to close  substantial
budget  gaps  in its  1990,  1991 and  1992 fiscal  years  in order  to maintain
balanced operating results. In order to  achieve a balanced budget for the  1992
fiscal  year,  the City  implemented various  actions, including  tax increases,
proposed service reductions and proposed productivity savings.
    
 
   
    1994-1997 NEW  YORK CITY  FINANCIAL  PLAN.   The  Mayor is  responsible  for
preparing the City's four-year financial plan. The City Council adopted a budget
for  the City's 1994  fiscal year on  June 14, 1993.  On July 2,  1993 the Mayor
announced additional expenditure reductions in the amount of approximately  $131
million for the City's 1994 fiscal year beyond those incorporated in the adopted
budget.  Based on the adopted budget and the additional reductions, the City has
prepared a proposed financial plan for  the 1994 through 1997 fiscal years  (the
"1994-1997  Financial Plan",  "Financial Plan"  or "City  Plan"), and  is in the
process of preparing a more detailed  financial plan, which will conform to  the
Financial  Plan and which the City expects to submit to the Control Board during
the first week of August, 1993.  The 1994-1997 Financial Plan projects  revenues
and expenditures for the 1994 fiscal year balanced in accordance with GAAP.
    
 
   
    The  City Plan sets forth actions to  close a projected gap of approximately
$2.0 billion  in the  1994 fiscal  year. The  gap-closing actions  for the  1994
fiscal  year include agency actions,  including productivity savings and savings
from restructuring the delivery of  City services; service reductions; the  sale
of
    
 
                                       16
<PAGE>
   
delinquent  real property tax receivables; discretionary transfers from the 1993
fiscal year; reduced debt service  costs, resulting from refinancings and  other
actions;  proposed increased Federal assistance;  a proposed continuation of the
personal income tax surcharge; proposed increased State aid; and various revenue
actions.
    
 
   
    The City Plan also sets forth  projections for the 1995 through 1997  fiscal
years and outlines a proposed gap-closing program to close projected budget gaps
of  $1.3 billion, $1.8 billion and $2.0 billion for the 1995 through 1997 years,
respectively. These projections take into account expected increases in  Federal
and  State assistance. Various actions proposed  in the City Plan, including the
proposed continuation  of the  personal income  tax surcharge  and the  proposed
increase  in State aid,  are subject to  approval by the  Governor and the State
Legislature, and the proposed increase in Federal aid is subject to approval  by
Congress  and the  President. The  State Legislature  has failed  to approve the
similar proposals for State assistance in previous sessions, thereby  increasing
the  uncertainty as to the receipt of  the State assistance included in the City
Plan. If these actions cannot be implemented, the City will be required to  take
other  actions  to  decrease expenditures  or  increase revenues  to  maintain a
balanced financial plan.
    
 
   
    The City  Plan reflects  certain cost  and expenditure  increases  including
increases  in salaries and  benefits paid to City  employees pursuant to certain
collective bargaining agreements and the costs associated with various  lawsuits
in  which the City has been named as a defendant. While the ultimate outcome and
fiscal impact,  if  any,  of  the  proceedings  and  claims  are  not  currently
predictable,  adverse determination  in certain  of them  might have  a material
adverse effect upon the City's ability to carry out the City Plan.
    
 
   
    RATINGS
    
   
    As of August  12, 1993, Moody's  rated the City's  general obligation  bonds
Baa1 and S&P rated such bonds A-. Such ratings reflect only the views of Moody's
and  S&P, from which an  explanation of the significance  of such ratings may be
obtained. There is no  assurance that such ratings  will continue for any  given
period  of time or that they will be revised downward or withdrawn entirely. Any
such downward revision or withdrawal could have an adverse effect on the  market
prices of bonds.
    
 
   
    OUTSTANDING INDEBTEDNESS
    
   
    As  of June 30, 1993, the City  and the Municipal Assistance Corporation for
the City of New  York had, respectively, $19.624  billion and $4.470 billion  of
outstanding net long-term debt.
    
 
   
    The  City depends  on the  State for State  aid both  to enable  the City to
balance its budget and to meet  its cash requirements. If the State  experiences
revenue  shortfalls or spending increases beyond its projections during its 1994
fiscal year or subsequent years, such developments could result in reductions in
anticipated State aid to the City. In  addition, there can be no assurance  that
State  budgets in future fiscal  years will be adopted  by the April 1 statutory
deadline and that there will not be adverse effects on the City's cash flow  and
additional City expenditures as a result of such delays.
    
 
   
    The  City's projections  set forth  in the  City Plan  are based  on various
assumptions and contingencies which are uncertain and which may not materialize.
Changes in major assumptions  could significantly affect  the City's ability  to
balance its budget as required by State law and to meet its annual cash flow and
financing requirements. Such assumptions and contingencies include the timing of
any regional and local economic recovery, the impact on real estate tax revenues
of the current downturn in the real estate market, the absence of wage increases
for  City  employees  in excess  of  the  increases assumed  in  the  City Plan,
employment growth, provision of State and Federal aid and mandate relief,  State
legislative  approval of future  State budgets, adoption of  City budgets by the
New York City Council, and approval by the Governor or the State Legislature  of
various other actions proposed in the City Plan.
    
 
   
    Implementation of the City Plan is also dependent upon the City's ability to
market  its securities  successfully in  the public  credit markets.  The City's
financing program for fiscal years  1994 through 1997 contemplates the  issuance
of  $10.8  billion  of general  obligation  bonds primarily  to  reconstruct and
rehabilitate the City's infrastructure and  physical assets and to make  capital
investments. In addition, the
    
 
                                       17
<PAGE>
   
City  issues revenue and tax anticipation  notes to finance its seasonal working
capital requirements. The success  of projected public sales  of City bonds  and
notes  will be subject to prevailing market  conditions, and no assurance can be
given that such sales  will be completed.  If the City were  unable to sell  its
general  obligation  bonds and  notes, it  would be  prevented from  meeting its
planned operating and capital expenditures.
    
 
   
    The City Comptroller  and other  agencies and public  officials have  issued
reports  and  made  public  statements which,  among  other  things,  state that
projected revenues  may be  less and  future expenditures  may be  greater  than
forecast  in the City Plan. In addition, the Control Board staff and others have
questioned whether the City has the capacity to generate sufficient revenues  in
the  future  to meet  the  costs of  its  expenditure increases  and  to provide
necessary services. It is reasonable to expect that such reports and  statements
will continue to be issued and to engender public comment.
    
 
   
    LITIGATION.   The City is  a defendant in a  significant number of lawsuits.
Such litigation includes, but is  not limited to, routine litigation  incidental
to  the performance of  its governmental and  other functions, actions commenced
and claims  asserted against  the  City arising  out of  alleged  constitutional
violations, alleged torts, alleged breaches of contracts and other violations of
law  and condemnation proceedings and other tax and miscellaneous actions. While
the ultimate outcome and  fiscal impact, if any,  on the proceedings and  claims
are  not currently predictable,  adverse determination in  certain of them might
have a material adverse  effect upon the  City's ability to  carry out the  City
Plan.  As of June 30, 1992, the City estimated its potential future liability on
account of all outstanding claims to be approximately $2.3 billion.
    
 
   
NEW YORK STATE
    
 
   
    RECENT DEVELOPMENTS.  The State has faced serious financial difficulties  in
recent  years. The effect of the national  recession has been more severe in the
State than  in  other parts  of  the nation,  and  the 1993-94  New  York  State
Financial  Plan (the "State Plan")  is based on an  economic projection that the
State will perform more poorly than the  nation as a whole. Although real  gross
domestic product grew modestly during calendar year 1992 and is expected to show
increased  growth  in calendar  year 1993,  preliminary  data indicate  that the
State's economy, as measured by employment, began to grow during the first  part
of  calendar  year  1993. Many  uncertainties  exist  in forecasts  of  both the
national and  State economies,  including  consumer attitudes  toward  spending,
Federal  financial and  monetary policies,  the availability  of credit  and the
condition of the world economy, which could have an adverse effect on the State.
There  can  be  no  assurance  that  the  State  economy  will  not   experience
worse-than-predicted  results  in the  1993-94  fiscal year,  with corresponding
material and  adverse  effects  on  the  State's  projections  of  receipts  and
disbursements.
    
 
   
    1993-94  FISCAL  YEAR.   The State  completed  its 1993  fiscal year  with a
cash-basis positive balance of  $67.1 million in the  State's General Fund  (the
major  operating fund  of the  State). The State's  1994 fiscal  year budget, as
enacted, projects a balanced General Fund.
    
 
   
    The State Plan projects General Fund receipts and transfers from other funds
at $32.367 billion  and disbursements and  transfers to other  funds at  $32.300
billion. Excess receipts of $67 million will be used for a required repayment to
the  State's Tax  Stabilization Reserve Fund.  In comparison  to the recommended
1993-94 Executive Budget, released  by the Governor in  early 1993, the  1993-94
State  budget, as enacted, reflects increases in both receipts and disbursements
in the General  Fund of  $811 million. The  $811 million  increase in  projected
receipts reflects many factors and assumptions, including (i) improving economic
conditions  and  higher-than-expected  tax  collections,  (ii)  improved 1992-93
results, (iii) additional payments from the Federal government to reimburse  the
State  for the  cost of  providing indigent  medical care,  (iv) the  payment of
additional personal income tax  refunds in the 1992-93  fiscal year which  would
otherwise  have  been paid  in fiscal  year  1993-94; offset  by revenue-raising
recommendations in the Executive Budget that  were not enacted and thus are  not
included in the State Plan. The $811 million increase in projected disbursements
reflects  (i) an increase in projected  school-aid payments, (ii) an increase in
projected payments for Medicaid assistance and other social
    
 
                                       18
<PAGE>
   
service programs,  (iii)  additional  spending on  the  judiciary  and  criminal
justice,  (iv) a net increase in  projected disbursements for all other programs
and purposes, and (v) establishment of a new contingency reserve.
    
 
   
    There can be no assurance that the State will not face substantial potential
budget  gaps  resulting  from  a  significant  disparity  between  tax  revenues
projected  from a  lower recurring  receipts base  and the  spending required to
maintain State programs at  current levels. To  address any potential  budgetary
imbalance,  the State  may need to  take significant actions  to align recurring
receipts and disbursements in future fiscal years.
    
 
   
    NEW YORK LOCAL  GOVERNMENT ASSISTANCE CORPORATION.   In 1990,  as part of  a
state  fiscal reform program, legislation was enacted creating the New York Loan
Government  Assistance  Corporation  ("LGAC"),  a  public  benefit   corporation
empowered  to  issue long-term  obligations to  fund  certain payments  to local
governments traditionally funded through the State's annual seasonal  borrowing.
The  legislation empowered  LGAC to issue  bonds and  notes in an  amount not in
excess of $4.7 billion (exclusive of certain refunding bonds) plus certain other
amounts. Over a period  of years, the issuance  of those long-term  obligations,
which  will be amortized  over no more than  30 years, is  expected to result in
eliminating the  need for  continuing short-term  seasonal borrowing  for  those
purposes. The legislation also imposed a cap on the annual seasonal borrowing of
the  State at $4.7 billion, less net proceeds of bonds issued by LGAC, except in
cases where the  Governor and the  legislative leaders have  certified both  the
need  for additional borrowing  and provided a  schedule for reducing  it to the
cap. If borrowing  above the cap  is thus permitted  in any fiscal  year, it  is
required  by law to  be reduced to the  cap by the fourth  fiscal year after the
limit was first  exceeded. As  of July  1, 1993, LGAC  has issued  its bonds  to
provide  net proceeds of approximately $3.680  billion. LGAC has been authorized
to issue its bonds to provide net  proceeds of up to an additional $703  million
during the State's 1993-94 fiscal year.
    
 
   
    COMPOSITION  OF STATE  CASH RECEIPTS  AND DISBURSEMENTS.   Substantially all
State  non-pension  financial  operations  are  accounted  for  in  the  State's
governmental  funds group,  Governmental funds  include the  General Fund, which
receives all income  not required by  law to  be deposited in  another fund  and
which  for the  State's 1993-94 fiscal  year comprises approximately  52% of the
total projected governmental fund receipts; Special Revenue Funds, which receive
the preponderance of moneys  received by the State  from the Federal  government
and  other income the use of which is legally restricted to certain purposes and
which comprised approximately 39% of total projected governmental funds receipts
in the  1993-94  fiscal  year;  Capital Projects  Funds,  used  to  finance  the
acquisition and construction of major capital facilities by the State and to aid
in   certain  of  such  projects  conducted   by  local  governments  or  public
authorities; and Debt  Service Funds,  which are  used for  the accumulation  of
moneys  for the payment  of principal of  and interest on  long-term debt and to
meet lease-purchase and  other contractual-obligation  commitments. Receipts  in
Capital  Projects and Debt Service Funds  comprise an aggregate of approximately
9% of total projected governmental funds receipts in the 1993-94 fiscal year.
    
 
   
    A legislative change implemented in August  1990 affects the way in which  a
portion of the State's sales and use tax collections are recorded as receipts in
the  General Fund. Pursuant to the legislation creating LGAC, the Comptroller is
required to credit the  equivalent of one percentage  point of the four  percent
sales  and use tax collections to the  Local Government Assistance Tax Fund (the
"Tax Fund"), which is a  Debt Service Fund, for  purposes of making payments  to
LGAC  to provide for the payment of debt  service on its bonds and notes. To the
extent that  these  moneys are  not  necessary for  payment  to LGAC,  they  are
transferred  from  the Tax  Fund to  the General  Fund and  are reported  to the
General Fund as a transfer  from other funds, rather than  as sales and use  tax
receipts. During the State's 1991-92 and 1992-93 fiscal years $1.435 billion and
$1.504 billion, respectively, in sales and use tax receipts were credited to the
Tax  Fund, and $1.527 billion is estimated to be credited to the Tax Fund during
the State's  1993-94  fiscal year.  For  the  1991-92 fiscal  year,  the  amount
transferred  to the  General Fund  from the Tax  Fund was  $1.316 billion, after
providing for the payment  of $119 million  to LGAC for  the purpose of  meeting
debt  service on  its bonds  and its  other cash  requirements. For  the 1992-93
fiscal year, $1.280  billion was transferred  to the General  Fund from the  Tax
Fund after providing for payment of $224
    
 
                                       19
<PAGE>
   
million  to  LGAC for  debt service  and other  cash requirements,  while $1.260
billion is estimated to be transferred in 1993-94, after payment of $267 million
to LGAC for debt service and other cash requirements.
    
 
   
    The enacted 1993-94 Executive Budget includes several changes in the  manner
in  which General Fund tax  receipts are recorded. Receipts  from user taxes and
fees are reduced  by approximately  $377 million  to reflect  receipts that  are
dedicated  for highway and bridge capital purposes, which are to be deposited in
the Capital Projects Funds.  Also, business taxes  are reduced by  approximately
$180  million  to reflect  tax receipts  that  are dedicated  for transportation
purposes and which will be deposited in the Special Revenue and Capital  Project
Funds.
    
 
   
    AUTHORITIES.   The fiscal  stability of the  State is related  to the fiscal
stability of its Authorities, which generally have responsibility for financing,
constructing  and   operating  revenue-producing   public  benefit   facilities.
Authorities are not subject to the constitutional restrictions on the incurrence
of  debt which apply to  the State itself, and may  issue bonds and notes within
the amounts of, and as otherwise restricted by, their legislative authorization.
As of September 30, 1992, the  latest data available, there were 18  Authorities
that  had outstanding  debt of $100  million or more.  The aggregate outstanding
debt, including refunding bonds, of these 18 Authorities was $62.2 billion as of
September 30, 1992,  of which  approximately $8.2 billion  was moral  obligation
debt  and  approximately  $17.1  billion was  financed  under  lease-purchase or
contractual-obligation financing arrangements.
    
 
   
    Authorities are generally  supported by revenues  generated by the  projects
financed  or operated, such  as fares, user  fees on bridges,  highway tolls and
rentals for dormitory rooms and housing. In recent years, however, the State has
provided financial  assistance  through  appropriations,  in  some  cases  of  a
recurring  nature,  to certain  of the  18 Authorities  for operating  and other
expenses and, in fulfillment of its commitments on moral obligation indebtedness
or otherwise,  for  debt  service.  This operating  assistance  is  expected  to
continue to be required in future years.
    
 
   
    The  State's  experience  has  been that  if  an  Authority  suffers serious
financial difficulties, both  the ability of  the State and  the Authorities  to
obtain  financing  in the  public credit  markets  and the  market price  of the
State's outstanding bonds  and notes  may be  adversely affected.  The New  York
State  Housing Finance Agency  ("HFA") and the New  York State Urban Development
Corporation ("UDC") have in the past required substantial amounts of  assistance
from  the State to meet debt service costs or to pay operating expenses. Further
assistance, possibly in increasing amounts, may be required for these, or other,
Authorities in the future. In  addition, certain statutory arrangements  provide
for  State local assistance payments otherwise  payable to localities to be made
under certain circumstances to certain Authorities. The State has no  obligation
to  provide additional assistance to  localities whose local assistance payments
have been paid to  Authorities under these arrangements.  However, in the  event
that  such local  assistance payments are  so diverted,  the affected localities
could seek additional State funds.
    
 
   
    RATINGS.  On June 6,  1990, Moody's changed its  ratings on all the  State's
outstanding general obligation bonds from A1 to A. On March 26, 1990, Standard &
Poor's  changed its ratings of all of the State's outstanding general obligation
bonds from AA- to A. On January 13, 1992, Standard & Poor's changed its  ratings
of all of the State's outstanding general obligation bonds from A to A-. Ratings
reflect  only the respective views of  such organizations, and an explanation of
the significance  of  such ratings  must  be  obtained from  the  rating  agency
furnishing  the  same.  There is  no  assurance  that a  particular  rating will
continue for  any given  period of  time or  that any  such rating  will not  be
revised  downward  or  withdrawn entirely  if,  in  the judgment  of  the agency
originally  establishing  the  rating,  circumstances  so  warrant.  A  downward
revision or withdrawal of such ratings, or either of them, may have an effect on
the  market price of the  State Municipal Securities in  which the New York Fund
invests.
    
 
   
    GENERAL OBLIGATION DEBT.  As of March 31, 1993, the State had  approximately
$5.132  billion in general obligation bonds, excluding refunding bonds, and $294
million in bond anticipation notes outstanding. On May 4, 1993, the State issued
$850 million in tax and revenue anticipation notes which will mature on December
31, 1993. Principal and  interest due on general  obligation bonds and  interest
    
 
                                       20
<PAGE>
   
due  on bond anticipation notes  and on tax and  revenue anticipation notes were
$890.0 million and  $818.8 million  for the  1991-92 and  1992-93 fiscal  years,
respectively,  and are  estimated to be  $789.1 million for  the State's 1993-94
fiscal year, not including interest on refunding bonds, issued in July 1992,  to
the extent that such interest is to be paid from escrowed funds.
    
 
   
    LITIGATION.    The  State  is  a  defendant  in  numerous  legal proceedings
pertaining to  matters incidental  to the  performance of  routine  governmental
operations.  Such litigation  includes, but is  not limited  to, claims asserted
against the State  arising from  alleged torts, alleged  breaches of  contracts,
condemnation proceedings and other alleged violations of State and Federal laws.
    
 
   
    Included  in  the  State's  outstanding litigation  are  a  number  of cases
challenging the constitutionality or the adequacy and effectiveness of a variety
of significant social  welfare programs primarily  involving the State's  mental
hygiene  programs. Adverse judgments in these  matters generally could result in
injunctive relief coupled with prospective  changes in patient care which  could
require substantial increased financing of the litigated programs in the future.
Because  of  the prospective  nature  of these  matters,  no provision  for this
potential exposure has been made in the State's audited financial statements for
the 1991-92 fiscal year.
    
 
   
    As a result of the United States Supreme Court decision in the case of STATE
OF DELAWARE v.  STATE OF NEW  YORK, the State  may be required  to make  certain
significant payments during the 1993-94 fiscal year or thereafter.
    
 
   
    Adverse  developments in any  of these proceedings or  the initiation of new
proceedings could affect the ability of  the State to maintain a balanced  State
Plan. In its audited financial statements for the 1991-92 fiscal year, the State
reported  its  estimated  liability  for  awarded  and  anticipated  unfavorable
judgments as $489 million.
    
 
   
    OTHER LOCALITIES.   Certain localities in  addition to the  City could  have
financial  problems leading to  requests for additional  State assistance during
the State's 1993-94  fiscal year  and thereafter.  The potential  impact on  the
State  of such actions by  localities is not included  in the projections of the
State receipts and disbursements in the State's 1993-94 fiscal year.
    
 
   
    Fiscal difficulties experienced by the City of Yonkers ("Yonkers")  resulted
in  the creation  of the Financial  Control Board  for the City  of Yonkers (the
"Yonkers Board")  by  the State  of  1984. The  Yonkers  Board is  charged  with
oversight of the fiscal affairs of Yonkers. Future actions taken by the Governor
or  the State Legislature to assist Yonkers  could result in allocation of State
resources in amounts that cannot yet be determined.
    
 
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 DWDC, shares of  the Fund are distributed  by the Distributor and
through certain  selected dealers  who  have entered  into agreements  with  the
Distributor  ("Selected Broker-Dealer")  at an 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.
    
 
   
    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 October  30, 1992,  the  current
Distribution  Agreement appointing the Distributor  exclusive distributor of the
Fund's shares and
    
 
                                       21
<PAGE>
   
providing for the  Distributor to bear  distribution expenses not  borne by  the
Fund.  The Distribution Agreement took effect on June 30, 1993 upon the spin-off
by Sears Roebuck  and Co. of  its remaining shares  of DWDC. By  its terms,  the
Distribution  Agreement has an initial term  ending April 30, 1994, and provides
that it 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 Company  (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 New York  Municipal
Money  Market 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, which are  rounded to the last  1/100 of a share). A
statement of the account will be  mailed to the shareholder after each  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 reserves  the right to  reject any  order for the  purchase of  its
shares.  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 sold with  either a front-end sales charge ("FESC  funds")
or  a contingent deferred  sales charge ("CDSC funds")  will be permitted, after
the shares  of  the Fund  acquired  by purchase  (not  by exchange  or  dividend
reinvestment)  have been held  for thirty 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 Tax-Free Daily  Income Trust, Dean
Witter California Tax-Free Daily  Income Trust, or  Dean Witter U.S.  Government
Money  Market  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 or Dean Witter Short-Term Bond Fund the foregoing eight non-FESC
or  CDSC funds  (these eight  funds are collectively  referred to  herein as the
"Exchange Funds.") There is no waiting period for shares acquired by exchange or
dividend reinvestment. Subsequently, shares of the Exchange Funds received in an
exchange for shares of an FESC fund  (regardless of the type of fund  originally
purchased)  may be redeemed and exchanged for shares of the Exchange Funds, FESC
funds or CDSC funds (however, shares of CDSC funds, including shares acquired in
exchange for (i) shares of FESC funds or (ii) shares of the Exchange Funds which
were acquired in exchange  for shares of  FESC funds, may  not be exchanged  for
shares of FESC funds).
    
 
                                       22
<PAGE>
   
Additionally, shares of the Exchange Funds received in an exchange for shares of
a  CDSC  fund (regardless  of  the type  of  fund originally  purchased)  may be
redeemed and  exchanged  for  shares  of  the  Exchange  Funds  or  CDSC  funds.
Ultimately, any applicable contingent deferred sales charge will have to be paid
upon  redemption of  shares originally purchased  from a CDSC  fund. 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 any  CDSC fund 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  deferred sales charge ("CDSC") at  the
time  of the exchange. During the period  of time the shareholder remains in the
Exchange Funds (calculated from the last day of the month in which the  Exchange
Fund shares were reacquired), the holding period or "year since purchase payment
made"  is frozen. When shares are redeemed  out of the Exchange Funds, they will
be subject  to  a  CDSC which  would  be  based  upon the  period  of  time  the
shareholder held shares in a CDSC fund. However, in the case of shares of a CDSC
fund 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 Exchange Fund  12b-1
distribution fees 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 CDSC  fund from  the
Exchange  Funds with no CDSC being imposed  on such exchange. The holding period
previously frozen when  shares were first  exchanged for shares  of an  Exchange
Fund  resumes on the last  day of the month  in which shares of  a CDSC fund are
reacquired. A CDSC is imposed only  upon an ultimate redemption, based upon  the
time  (calculated as  described above)  the shareholder  was invested  in a CDSC
fund. Shares of a CDSC fund acquired in exchange for shares of an FESC fund  (or
in  exchange for shares of  other Dean Witter Funds for  which shares of an FESC
fund have been exchanged) are not subject to any CDSC upon their redemption.
    
 
   
    When shares initially purchased in a  CDSC fund are exchanged for shares  of
another CDSC fund or for 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 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 FESC funds, or  for
shares  of other  Dean Witter  Funds for  which shares  of FESC  funds have been
exchanged (all  such shares  called  "Free Shares"),  will be  exchanged  first.
Shares  of Dean  Witter American  Value Fund acquired  prior to  April 30, 1984,
shares of Dean Witter  Dividend Growth Securities Inc.  and Dean Witter  Natural
Resource  Development Securities Inc. acquired prior to July 2, 1984, and shares
of Dean Witter  Strategist Fund  acquired prior to  November 8,  1989, are  also
considered  Free Shares and will be the first Free Shares to be exchanged. After
an exchange,  all  dividends  earned on  shares  in  an 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
    
 
                                       23
<PAGE>
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 CDSC fund 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.
 
    The  Transfer Agent acts as agent for  shareholders of the Fund in effecting
redemptions of Fund shares and in applying the proceeds to the purchase of other
fund shares. In  the absence  of negligence on  its part,  neither the  Transfer
Agent  nor the Fund shall be liable for  any redemption of Fund shares caused by
unauthorized telephone instructions.  Accordingly, in such  event, the  investor
shall bear the risk of loss. The staff of the Securities and Exchange Commission
is currently considering the propriety of such a policy.
 
   
    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, DWR 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.
    
 
   
    DWR 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.
    
 
   
    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.
    
 
    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  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 Account may not thereafter be
placed back into that Account. If such a shareholder
 
                                       24
<PAGE>
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 is $10,000 for
Dean Witter  Short-Term U.S.  Treasury Trust  (although that  fund may,  in  its
discretion,  accept initial purchases as low as $5,000) and $5,000 for the Fund,
Dean Witter Liquid Asset Fund Inc., Dean Witter Tax-Free Daily Income Trust, and
Dean Witter California Tax-Free Daily Income Trust, although those funds may, at
their discretion, accept initial  investments of as low  as $1,000. The  minimum
initial  investment  for 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 an Exchange Fund,  pursuant to the 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 that 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.
    
 
   
    For  further  information  regarding  the  Exchange  Privilege, shareholders
should contact  DWR or  other selected  broker-dealer account  executive or  the
Transfer Agent.
    
 
PLAN OF DISTRIBUTION
 
   
    In  accordance with a Plan of Distribution  pursuant to Rule 12b-1 under the
Act between the Fund and Dean Witter Distributors Inc. (the "Distributor"),  the
Distributor  provides certain services in connection with the promotion of sales
of Fund shares  (the "Plan"  refers to the  Plan and  Agreement of  Distribution
prior  to  the  reorganization  and  to  the  Plan  of  Distribution  after  the
reorganization). The Plan was approved by the Board of Trustees on February  15,
1990  and by DWR as the Fund's  sole shareholder on February 16, 1990, whereupon
the Plan went into effect. The vote of the Trustees, which was cast in person at
a meeting called for the purpose of voting on such Plan, 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").  The Shareholders  of the Fund  subsequently approved the  Plan at a
Special Meeting of Shareholders held on June 20, 1991.
    
 
    The Plan provides that the Distributor  bear the expense of all  promotional
and  distribution related activities on behalf  of the Fund, except for expenses
that the Trustees determine to reimburse, as
 
                                       25
<PAGE>
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 dealer's 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.
 
    DWR  account executives are paid an  annual residual commission, currently a
gross residual of up to  0.10% of the current  value of the respective  accounts
for  which they are the account executives  of record. The "gross residual" is a
charge which reflects residual commissions paid by DWR to its account executives
and DWR's  expenses associated  with the  servicing of  shareholder's  accounts,
including  the expenses of operating DWR's branch offices in connection with the
servicing of shareholder's  accounts, which  expenses include  lease costs,  the
salaries  and  employee  benefits  of operations  and  sales  support personnel,
utility costs, communications costs and the costs of stationery and supplies and
other expenses relating to branch office serving of shareholder accounts.
 
   
    The Fund is  authorized to  reimburse specific  expenses incurred  or to  be
incurred  in promoting the  distribution of the  Fund's shares. Reimbursement is
made through monthly payments  in amounts determined in  advance of each  fiscal
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 will be incurred  for
which  reimbursement  payments under  the  Plan will  be  made. In  addition, no
interest charges, if any, incurred on  any distribution expense incurred by  the
Distributor or other selected dealers pursuant to the Plan, will be reimbursable
under  the Plan. In making  quarterly determinations of the  amounts that may be
expended by the Fund, the Investment Manager provides and the Trustees review  a
quarterly  budget of projected incremental  distribution expenses to be incurred
on behalf  of the  Fund, together  with  a report  explaining the  purposes  and
anticipated  benefits of incurring  such expenses. The  Trustees determine which
particular expenses, and the  portions thereof, that may  be borne by the  Fund,
and in making such a determination shall consider the scope of the Distributor's
commitment  to  promoting  the  distribution  of  the  Fund's  shares.  The Fund
reimbursed $43,843 to  the Distributor pursuant  to the Plan  which amounted  to
0.10  of 1% of the  Fund's average daily net assets  for the year ended December
31, 1993.  Based upon  the total  amounts spent  by the  Distributor during  the
period,  it is estimated that the amount paid by the Fund to the Distributor for
distribution   was   spent   in   approximately   the   following   ways:    (i)
advertising--$-0-;  (ii) printing and mailing prospectuses to other than current
shareholders--$-0-; (iii) compensation to underwriters--$-0-; (iv)  compensation
to  dealers--$-0-; (v)  compensation to  sales personnel--$-0-;  and (vi) other,
which accrued for expenses relating to compensation of sales personnel and other
miscellaneous expenses--$43,843.  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.
 
   
    Continuance of the Plan until April  30, 1994 was approved by the  Trustees,
including a majority of the Independent 12b-1 Trustees, at their meeting held on
April  28, 1993. In making their determination  to continue the Plan until April
30, 1994, the  Board of  Trustees, including  all of  the Independent  Trustees,
arrived at the conclusion that the Plan the Directors were provided at the April
28,  1993 meeting had  benefitted 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 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
    
 
                                       26
<PAGE>
   
reasonable  likelihood that the Plan  will continue to benefit  the Fund and its
shareholders. 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  Trustees is  committed  to the  discretion of  the  Independent
Trustees.
    
 
   
    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 Distibutor is also authorized to retain part of such fee
as compensation for its own distribution-related expenses.
    
 
   
    Under  the  Plan,  the Distributor  provides  the  Fund, for  review  by the
Trustees, and  the Trustees  review, promptly  after the  end of  each  calendar
quarter,  a  written  report  regarding  the  incremental  distribution expenses
incurred on  behalf of  the  Fund during  such  calendar quarter,  which  report
includes (1) an itemization of the types of expenses and the purposes therefore;
(2)  the amounts of such expenses; and (3) a description of the benefits derived
by the Fund. In  the Trustees' quarterly  review of the  Plan they consider  its
continued appropriateness and the level of compensation provided therein.
    
 
    No  interested person of the Fund nor any  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,  DWR 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;  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
 
                                       27
<PAGE>
would result from investment  in such a similar  company and existing  investors
would  receive  less (more)  investment income.  The purpose  of this  method of
calculation is to facilitate the maintenance  of a constant net asset value  per
share of $1.00.
 
    The  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 is conditioned on
its compliance with various conditions contained in the Rule including: (a)  the
Trust's  Trustees  are  obligated,  as a  particular  responsibility  within the
overall duty of care owed to  the Trust'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 Trust 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 1/2 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 Trust;  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 Trust'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 Trust.
 
    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 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  thirteen 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 Trust'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.
 
                                       28
<PAGE>
    An Eligible Security is defined  in the Rule to  mean a security which:  (a)
has  a remaining maturity of thirteen months or less: (b)(i) is rated in the two
highest short-term  rating categories  by any  two NRSRO's  that have  issued  a
short-term  rating with respect to the security  or class of debt obligations of
the issuer,  or (ii)  if only  one NRSRO  has issued  a short-term  rating  with
respect to the security, then by that NRSRO; (c) was a long-term security at the
time of issuance whose issuer has outstanding a short-term debt obligation which
is  comparable in priority and security and  has a rating as specified in clause
(b) above; or (d) if no rating is  assigned by any NRSRO as provided in  clauses
(b)  and (c)  above, the unrated  security is determined  by the Board  to be of
comparable quality to any such rated security.
 
    As permitted by the Rule, the Board has delegated to the Trust'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.
 
    If the Board determines that  it is no longer in  the best interests of  the
Trust  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.
 
    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 or
repurchased 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  repurchases or
postpone the date of payment (1) for any periods during which the New York Stock
Exchange is closed (other than for
 
                                       29
<PAGE>
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  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  60 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.
    
 
    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  $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. 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 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.
 
    In computing net investment income, the Fund will amortize any premiums  and
original  issue discounts on  securities owned, if  applicable. Capital gains or
losses realized upon sale or maturity of such securities will be based on  their
amortized cost.
 
                                       30
<PAGE>
    The  Fund  has qualified  and  intends to  remain  qualified as  a regulated
investment company under Subchapter M of  the Internal Revenue Code of 1986,  as
amended  (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 in which 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  total
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.
 
    The Trustees may  revise the  dividend policy,  or postpone  the payment  of
dividends,  if the Fund should have  or anticipate any large unexpected expense,
loss or fluctuation in net assets which,  in the opinion of the Trustees,  might
have  a significant  adverse effect  on shareholders.  On occasion,  in order to
maintain a constant  $1.00 per share  net asset value,  the Trustees may  direct
that  the number of outstanding shares be reduced in each shareholder's account.
Such reduction may result in taxable income, if any, to a shareholder in  excess
of  the net  increase (i.e.,  dividends, less such  reductions), if  any, in the
shareholder's account for a period. Furthermore, such reduction may be  realized
as a capital loss when the shares are liquidated.
 
    A  number of provisions included  in the Code by the  Tax Reform Act of 1986
may affect  the federal  income tax  liability of  the Fund's  shareholders,  by
reducing  the  individual  and  corporate income  tax  rates  and  expanding the
alternative minimum tax provisions.  In general, lower  rates of taxation  could
make  tax-exempt bonds less attractive to investors and could decrease the value
of the tax-exempt securities  held by the  Fund and the net  asset value of  the
Fund's  shares. Furthermore, some of the changes  may reduce the extent to which
issuers may issue tax-exempt bonds. The  Code now subjects interest received  on
certain  otherwise  tax-exempt  securities  to  alternative  minimum  tax.  This
alternative minimum tax would  apply 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 substantial portion of  the Fund's investments may be in
such "private activity bonds", with the result that a substantial 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. The Fund  will report to
shareholders the portion of its dividends  declared during the year which are  a
tax preference item for alternative minimum tax purposes, as well as the overall
percentage   of   dividend  distributions   which   constitutes  exempt-interest
dividends. Individual taxpayers are generally subject to the alternative minimum
tax if their  "regular tax"  liability is less  than 24%  of their  "alternative
minimum  taxable  income" reduced  by  an exemption  amount  ranging from  $0 to
$40,000 depending  upon the  taxpayer's income  and filing  status.  Alternative
minimum  taxable  income  is  generally equal  to  taxable  income  with certain
adjustments and increased by certain "tax preference items" which may include  a
portion  of  the Fund's  dividends  as described  above.  In addition,  the Code
further provides that  corporations are  subject to an  alternative minimum  tax
based, in part, on 75% of any excess of "adjusted current earnings" over taxable
income  as  adjusted  for  other  tax  preferences.  Because  an exempt-interest
dividend paid  by  the Fund  will  be  included in  computing  adjusted  current
earnings,  a corporate shareholder may therefore be required to pay an increased
alternative minimum tax  as the  result of  receiving exempt-interest  dividends
paid by the Fund.
 
    The  Code provides  that every  person required  to file  a tax  return must
include on such return the amount of exempt-interest dividends received from the
Fund during the taxable year.
 
    The I Amendments  and Reauthorization Act  of 1986 (the  "I Act") imposes  a
deductible  tax on a corporation's  alternative minimum taxable income (computed
without regard to the alternative tax net
 
                                       31
<PAGE>
operating loss deduction) at  a rate of $12  per $10,000 (0.12%) of  alternative
minimum  taxable income  in excess  of $2,000,000. The  tax will  be imposed for
taxable years beginning after December 31, 1986 and before January 1, 1996.  The
tax  will  be  imposed  even  if  the corporation  is  not  required  to  pay an
alternative minimum tax because the  corporation's regular income tax  liability
exceeds  its minimum tax  liability. Exempt-interest dividends  paid by the Fund
that create alternative minimum tax preferences for corporate shareholders under
the Code (as described above) may be subject to the 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
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  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.
 
    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.
 
    The Code requires each regulated  investment company to pay a  nondeductible
4%  excise  tax to  the  extent the  company  does not  distribute,  during each
calendar year, 98% of its ordinary income, determined on a calendar year  basis,
and  98% of its capital gains, determined in  general on an October 31 year end,
plus  certain   undistributed  amounts   from  previous   years.  The   required
distributions,  however, are  based only  on the  taxable income  of a regulated
investment company. The excise tax, therefore,  will generally not apply to  the
tax-exempt  income of a regulated investment company such as the Trust that pays
exempt-interest dividends. The  Fund anticipates  that it  will make  sufficient
timely distributions to avoid imposition of the excise tax.
 
    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 for investment by the Fund could be affected. In that event, the Fund
would re-evaluate its investment objective and policies.
 
    To  the  extent  that  dividends  are  derived  from  interest  on  New York
tax-exempt securities, such dividends  will also be exempt  from New York  State
and  City personal income taxes. Interest  on indebtedness incurred or continued
to purchase  or carry  shares of  an investment  company paying  exempt-interest
dividends,  such as the Fund, may not be deductible by the investor for State or
City personal income tax purposes.

    The foregoing relates to federal income  taxation and to New York State  and
City  personal income taxation  as in effect  as of the  date of the Prospectus.
Distributions   from   investment   income   and   capital   gains,    including
exempt-interest  dividends,  may  be  subject to  New  York  franchise  taxes if
received by a corporation doing business in  New York, to state taxes in  states
other than New York and to local taxes.
 
    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, 1993  was
1.66%. The effective annual yield on 1.66% is 1.68% 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 for the
current yield), the net change, exclusive  of capital changes and including  the
value  of additional shares purchased with  dividends and any dividends declared
therefrom (which  reflect  deductions  of  all expenses  of  the  Fund  such  as
management  fees), in the value of  a hypothetical pre-existing account having a
balance of one share at the beginning of the period, and dividing the difference
by the value of the  account at the beginning of  the base period to obtain  the
base  period return, and  then compounding the  base period return  by adding 1,
raising the sum to a power equal to 365 divided by 7, and subtracting 1 from the
result.
 
    The yields quoted in any advertisement or other communication should not  be
considered  a representation of the  yields of the Fund  in the future since the
yield is not fixed. Actual yields will depend not only on the type, quality  and
maturities  of the investments held by the Fund and changes in interest rates on
such investments, but also on changes in the Fund's expenses during the period.
 
    Yield information may be useful in reviewing the performance of the Fund and
for providing  a  basis  for  comparison  with  other  investment  alternatives.
However,  unlike bank deposits or other  investments which typically pay a fixed
yield for a stated period of time, the Fund's yield fluctuates.
 
   
    Based upon a combined  Federal and New York  personal income tax bracket  of
41.96%,  the Fund's tax-equivalent yield for  the seven days ending December 31,
1993 was 2.86%.
    
 
   
    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 $11,194, $55,970 and $111,940, respectively, at December 31, 1993.

RATINGS OF INVESTMENTS
 
MOODY'S INVESTORS SERVICE INC. ("MOODY'S")
 
                             MUNICIPAL BOND RATINGS
 
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.
 
    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.
 
                                       36
<PAGE>
    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.
 
                             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.
 
                                       37
<PAGE>
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.
 
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 implied "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 "CI" 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",  "CC" 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" to "CCC" may be modified  by
      the  addition of a plus  or minus sign to  show relative standing with 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.
 
                                       38
<PAGE>
                             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.
 
                            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.



                                        2

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

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 (the "Act") may be permitted to trustees, officers and controlling
persons of the Registrant pursuant to the foregoing provisions or otherwise, the
Registrant has been advised that in the opinion of the  Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable.  In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a trustee, officer, or controlling person of the Registrant
in connection with the successful defense of any action, suit or proceeding) is
asserted against the Registrant by such trustee, officer or controlling person
in connection with the shares being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act, and will
be governed by the final adjudication of such issue.

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

     Registrant, in conjunction with the Investment Manager, Registrant's
Trustees, and other registered investment management companies managed by the
Investment Manager, maintains insurance on behalf of any person who is or was a
Trustee, officer, employee, or agent of Registrant, or who is or was serving at
the request of Registrant as a trustee, director, officer, employee or agent of
another trust or corporation, against any liability asserted against him and
incurred by him or arising out of his position.  However, in no event will
Registrant maintain insurance to indemnify any such person for any act for which
Registrant itself is not permitted to indemnify him.

                        INVESTMENT MANAGEMENT AGREEMENT
 
    AGREEMENT  made as of the 30th day of  June, 1993 by and between Dean Witter
New  York  Municipal  Money  Market  Trust,  an  unincorporated  business  trust
organized  under  the laws  of  the Commonwealth  of  Massachusetts (hereinafter
called the "Fund"), and  Dean Witter InterCapital  Inc., a Delaware  corporation
(hereinafter called the "Investment Manager"):
 
    WHEREAS,  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, The Investment Manager is registered as an investment adviser under
the Investment Advisers Act of  1940, and engages in  the business of acting  as
investment adviser; and
 
    WHEREAS,  The  Fund  desires  to retain  the  Investment  Manager  to render
management and investment advisory services in  the manner and on the terms  and
conditions hereinafter set forth; and
 
    WHEREAS,  The Investment Manager desires to  be retained to perform services
on said terms and conditions:
 
    Now, Therefore, this Agreement
 
                              W I T N E S S E T H:
 
that in  consideration of  the  premises and  the mutual  covenants  hereinafter
contained, the Fund and the Investment Manager agree as follows:
 
     1.  The Fund  hereby retains  the Investment  Manager to  act as investment
manager of  the  Fund  and, subject  to  the  supervision of  the  Trustees,  to
supervise  the  investment  activities of  the  Fund as  hereinafter  set forth.
Without limiting the generality of  the foregoing, the Investment Manager  shall
obtain  and  evaluate  such  information and  advice  relating  to  the economy,
securities markets and securities as it  deems necessary or useful to  discharge
its  duties hereunder;  shall continuously  manage the assets  of the  Fund in a
manner consistent with the investment objectives and policies of the Fund; shall
determine the securities to be purchased,  sold or otherwise disposed of by  the
Fund  and the timing of  such purchases, sales and  dispositions; and shall take
such further action, including the placing of purchase and sale orders on behalf
of the Fund, as the Investment Manager shall deem necessary or appropriate.  The
Investment  Manager shall also furnish  to or place at  the disposal of the Fund
such of  the  information,  evaluations, analyses  and  opinions  formulated  or
obtained  by the Investment Manager  in the discharge of  its duties as the Fund
may, from time to time, reasonably request.
 
     2. The Investment Manager  shall, at its own  expense, maintain such  staff
and  employ or retain such  personnel and consult with  such other persons as it
shall from time to time determine to  be necessary or useful to the  performance
of  its obligations under this Agreement. Without limiting the generality of the
foregoing, the staff and personnel of the Investment Manager shall be deemed  to
include  persons employed  or otherwise  retained by  the Investment  Manager to
furnish statistical and  other factual data,  advice regarding economic  factors
and  trends, information with respect  to technical and scientific developments,
and such other information, advice and assistance as the Investment Manager  may
desire. The Investment Manager shall, as agent for the Fund, maintain the Fund's
records and books of account (other than those maintained by the Fund's transfer
agent,  registrar, custodian  and other agents).  All such books  and records so
maintained shall be  the property of  the Fund and,  upon request therefor,  the
Investment  Manager shall surrender to the Fund such of the books and records so
requested.
 
     3. The Fund will, from time to time, furnish or otherwise make available to
the Investment  Manager  such  financial reports,  proxy  statements  and  other
information  relating to the business and affairs  of the Fund as the Investment
Manager may reasonably require in order to discharge its duties and  obligations
hereunder.
 
     4.  The Investment Manager shall bear  the cost of rendering the investment
management and supervisory services to be performed by it under this  Agreement,
and  shall,  at  its own  expense,  pay  the compensation  of  the  officers and
employees, if any, of the Fund, and provide such office space and equipment  and
such  clerical and bookkeeping services as  the Fund shall reasonably require in
the conduct  of  its  business,  including  the  pricing  of  Fund  shares,  and
preparation   of   prospectuses,   proxy   statements   and   reports   required
<PAGE>
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' commissions chargeable
to the Fund in  connection with portfolio securities  transactions to which  the
Fund  is a party;  all taxes, including securities  issuance and transfer taxes,
and fees payable by the Fund  to Federal, State or other governmental  agencies;
the  cost and expense  of engraving or  printing share certificates representing
shares of the Fund; all costs  and expenses in connection with the  registration
and  maintenance of registration of the Fund  and its shares with the Securities
and Exchange Commission  and various states  and other jurisdictions  (including
filing  fees and legal fees and disbursements  of counsel); the cost and expense
of printing (including  typesetting) and distributing  prospectuses of the  Fund
and   supplements  thereto   to  the   Fund's  shareholders;   all  expenses  of
shareholders' and  Trustees' meetings  and of  preparing, printing  and  mailing
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 regulations,  will
reimburse  the  Fund for  annual  operating expenses  in  excess of  any expense
limitation that
 
                                       2
<PAGE>
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, 1994 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.
 
    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
 
                                       3
<PAGE>
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,  Dean  Witter
Reynolds  Inc., or any  corporate affiliate of  the Investment Manager's parent,
may use or  grant to  others the right  to use  the name "Dean  Witter," or  any
combination  or abbreviation  thereof, as  all or  a 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  New York Municipal
Money Market Trust, dated December 28, 1989, 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  New York Municipal Money  Market Trust refers to  the Trustees under the
Declaration collectively as Trustees, but not as individuals or personally;  and
no  Trustee, shareholder,  officer, employee  or agent  of Dean  Witter New York
Municipal Money Market Trust shall be held to any personal liability, nor  shall
resort  be had to their private property  for the satisfaction of any obligation
or claim or otherwise, in  connection with the affairs  of said Dean Witter  New
York Municipal Money Market 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 above written in New York, New York.

                DEAN WITTER NEW YORK MUNICIPAL MONEY MARKET TRUST

                              DISTRIBUTION AGREEMENT



     AGREEMENT made as of this 30th day of June, 1993 between Dean Witter New
York Municipal Money Market 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 non-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
(defined below) 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.

     (b) The Shares are to be resold by the Distributor at the net asset value
per share, 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(d) 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.



                                        1

 <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).

     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 be made by
the Fund to the Distributor for the account of the shareholder. The Distributor
shall be responsible for the accuracy of instructions transmitted to the Fund's
transfer agent in connection with all such repurchases.

     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 to
instruct the Fund to transmit payments for such redemptions 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
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.

     (d) 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.

Distributor, of all financial statements prepared by the Fund and examined by
independent accountants. The Fund shall, at the expense of the Distributor, make
available to the Distributor such number of copies of the prospectus as the

such qualification may be withheld, terminated or withdrawn by the Fund at any
time in its discretion. As provided in Section 8(c) hereof, the expense of
qualification and maintenance of qualification shall be borne by the Fund. The
Distributor shall furnish such information and other material relating to its
affairs and activities as may be required by the Fund in connection with such
qualification.

     (d) The Fund shall, at the expense of the Distributor, furnish, in
reasonable quantities upon request by the Distributor, copies of annual and

of the Fund through DWR and may sell Shares through other securities dealers and
its own Account Executives and shall devote reasonable time and effort to
promote sales of Shares, but shall not be obligated to sell any specific number
of Shares. The services of the Distributor hereunder are not exclusive and it is
understood that the Distributor acts as principal underwriter for other
registered investment companies and intends to do so in the future. It is also
understood that Selected Dealers, including DWR, may also sell shares for other
registered investment companies.

     (b) The Distributor and any Selected Dealers and any Selected Dealers shall
not give any information or make any representations, other than those contained

specifically approved by the Fund.

     (c) The Distributor agrees that it will comply with the terms and
limitations of the Rules of Fair Practice of the National Association of
Security Dealers, Inc. (NASD).

     SECTION 7. SELECTED DEALERS AGREEMENTS. (a) The Distributor shall have the
right to enter into selected dealers agreements with Selected Dealers for the
sale of Shares. In making agreements with Selected Dealers, the Distributor
shall act only as principal and not as agent for the Fund. Shares sold to
Selected Dealers shall be for resale by such dealers only at the public offering
price set forth in the Prospectus.

     (b) Within the United States, the Distributor shall offer and sell Shares
only to Selected Dealers that are members in good standing of the NASD.

     (c) The Distributor shall adopt and follow procedures, as approved by the
Fund, for the confirmation of sales of Shares to investors and Selected Dealers,
the collection of amounts payable by investors and Selected Dealers on such
sales, and the cancellation of unsettled transactions, as may be necessary to
comply with the requirements of the NASD, as such requirements may from time to
time exist.

     SECTION 8. PAYMENT OF EXPENSES. (a) The Distributor shall bear all expenses
incurred by it in connection with its duties and activities under this Agreement
(except such expenses as are specifically undertaken herein by the Fund). It is
understood and agreed that, so long as the Fund's Plan of Distribution pursuant
to Rule 12b-1 (the "Rule 12b-1 Plan") continues in effect, any expenses incurred
by the Distributor and DWR in connection with the sale of Shares may be paid
from amounts the Distributor and DWR are entitled to receive from the Fund under
such Plan.

     (b) The Fund shall bear all costs and expenses of the Fund, including fees
and disbursements of legal counsel including counsel to the Trustees of the Fund
who are not interested persons (as defined in the 1940 Act) of the Fund or the

                                        3

<PAGE>

preparation and filing of any required Registration Statements and Prospectuses
and all amendments and supplements thereto, and the expenses of preparing,
printing, mailing and otherwise distributing prospectuses and statements of
additional information, annual or interim reports or proxy materials to
shareholders.

     (c) The Fund shall bear the cost and expenses of qualification of the
Shares for sale, and, if necessary or advisable in connection therewith, of
qualifying the Fund as a broker or dealer, in such states of the United States
or other jurisdictions as shall be selected by the Fund and the Distributor
pursuant to Section 5(c) hereof and the cost and expenses payable to each such
state for continuing qualification therein until the Fund decides to discontinue
such qualification pursuant to Section 5(c) hereof.

     SECTION 9. INDEMNIFICATION. (a) The Fund shall indemnify and hold harmless
the Distributor and each person, if any, who controls the Distributor against
any loss, liability, claim, damage or expense (including the reasonable cost of
investigating or defending any alleged loss, liability, claim, damage or expense
and reasonable counsel fees incurred in connection therewith), arising by reason
of any person acquiring any Shares, which may be based upon the 1933 Act, or on
any other statute or at common law, on the ground that the Registration
Statement or related Prospectus as from time to time may be amended and
supplemented, or the annual or interim reports to shareholders of the Fund,
includes an untrue statement of a material fact or omits to state a material
fact required to be stated therein or necessary in order to make the statements
therein not misleading, unless such statement or omission was made in reliance
upon, and in conformity with, information furnished to the Fund 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 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 may be amended, or the annual or interim reports to
shareholders.



                                        4

<PAGE>

     (ii) The Distributor shall idemnify and hold harmless the Fund and 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
subsection 4(c) 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 subsection 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, 1994 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.

penalty, by the Trustees of the Fund, by a majority of the Trustees of the Fund

financial interest in this Agreement or in any agreement related to the Fund's
Rule 12b-1 Plan, 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 "interest 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 that 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 Trust establishing Dean
Witter New York Municipal Money Market Trust, dated December 28, 1989, 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 New York Municipal Money Market Trust, refers to the
Trustees under the Declaration collectively as Trustees, but not as individuals
or personally; and no Trustee, shareholder, officer, employee or agent of Dean
Witter New York Municipal Money Market Trust shall be held to any personal
liability, nor shall resort be had to their private property for the
satisfaction of any obligation or claim or otherwise, in connection with the
affairs of said Dean Witter New York Municipal Money Market Trust but the Trust
Estate only shall be liable.

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

                         DEAN WITTER DISTRIBUTORS INC.
 
Gentlemen:
 
    Dean  Witter  Distributors  Inc.  (the  "Distributor")  has  a  distribution
agreement (the "Distribution  Agreement") with  Dean Witter  New York  Municipal
Money  Market Trust,  a Massachusetts business  trust (the  "Fund"), pursuant to
which it acts as the Distributor for the sale of the Fund's shares of beneficial
interest, par  value $0.01  per  share (the  "Shares"). Under  the  Distribution
Agreement, the Distributor has the right to distribute Shares for resale.
 
    The  Fund is an open-end management  investment company registered under the
Investment Company Act of 1940, as amended, and the Shares being offered to  the
public  are registered under  the Securities Act  of 1933, as  amended. You have
received a  copy of  the Distribution  Agreement  between us  and the  Fund  and
reference  is made herein to certain  provisions of such Distribution Agreement.
The terms used  herein, including "Prospectus"  and "Registration Statement"  of
the  Fund and "Selected Dealer" shall have the same meaning in this Agreement as
in the Distribution  Agreement. As principal,  we offer to  sell shares to  your
customers, upon the following terms and conditions:
 
    1.  In all sales  of Shares to  the public you  shall act on  behalf of your
customers, and in no transaction  shall you have any  authority to act as  agent
for the Fund, for us or for any Selected Dealer.
 
    2.  Orders received from  you will be  accepted through us  or on our behalf
only at  the net  asset value  applicable to  each order,  as set  forth in  the
current  Prospectus. The procedure  relating to the handling  of orders shall be
subject to instructions which we or the Fund shall forward from time to time  to
you. All orders are subject to acceptance or rejection by the Distributor or the
Fund in the sole discretion of either.
 
    3.  You  shall not  place  orders for  any  Shares unless  you  have already
received purchase orders for such Shares at the applicable net asset values  and
subject  to  the  terms  hereof  and  of  the  Distribution  Agreement  and  the
Prospectus. You agree that you will not  offer or sell any of the Shares  except
under  circumstances that will result in  compliance with the applicable Federal
and state securities laws and that in  connection with sales and offers to  sell
Shares  you will furnish to each person to whom any such sale or offer is made a
copy of the Prospectus (as then amended or supplemented) and will not furnish to
any person any information relating to the Shares, which is inconsistent in  any
respect  with the  information contained in  the Prospectus (as  then amended or
supplemented) or cause any advertisement to be published by radio or  television
or  in any newspaper or posted in any  public place or use any sales promotional
material without our consent and the consent of the Fund.
 
    4. The Distributor will compensate you for  sales of shares of the Fund  and
personal services to Fund shareholders by paying you a sales charge and/or other
commission  (which may be in  the form of a gross  sales credit and/or an annual
residual commission) and/or a service fee, under  the terms as are set forth  in
the Fund's Prospectus.
 
    5.  If any Shares sold  to your customers under  the terms of this Agreement
are repurchased by us for the account of the Fund or are tendered for redemption
within seven business days  after the date of  the confirmation of the  original
purchase  by you, it is agreed that you  shall forfeit your right to, and refund
to us, any commission received by you with respect to such Shares.
 
    6. No person is authorized to make any representations concerning the Shares
or the Fund except those contained in the current Prospectus and in such printed
information subsequently issued by us or the Fund as information supplemental to
such Prospectus. In selling Shares, you shall rely solely on the representations
contained in the  Prospectus and supplemental  information mentioned above.  Any
printed  information  which we  furnish you  other than  the Prospectus  and the
Fund's  periodic  reports   and  proxy  solicitation   material  are  our   sole
responsibility  and not the responsibility  of the Fund, and  you agree that the
Fund shall have no liability or  responsibility to you in these respects  unless
expressly assumed in connection therewith.
 
                                       1
<PAGE>
    7. You agree to deliver to each of the purchasers making purchases a copy of
the then current Prospectus at or prior to the time of offering or sale, and you
agree  thereafter to deliver to such purchasers copies of the annual and interim
reports and  proxy solicitation  materials of  the Fund.  You further  agree  to
endeavor  to  obtain  proxies from  such  purchasers. Additional  copies  of the
Prospectus, annual or interim  reports and proxy  solicitation materials of  the
Fund will be supplied to you in reasonable quantities upon request.
 
    8.  You are hereby authorized (i) to  place orders directly with the Fund or
its agent for  shares of the  Fund to be  sold by us  subject to the  applicable
terms  and conditions governing the placement of orders for the purchase of Fund
shares, as set forth  in the Distribution Agreement,  and (ii) to tender  shares
directly to the Fund or its agent for redemption subject to the applicable terms
and conditions set forth in the Distribution Agreement.
 
    9.  We reserve the right in our discretion, without notice, to suspend sales
or withdraw the offering of Shares entirely. Each party hereto has the right  to
cancel this agreement upon notice to the other party.
 
    10.  I.  You shall  indemnify and  hold harmless  the Distributor,  from and
against any claims, damages  and liabilities which arise  as a result of  action
taken  pursuant to  instructions from  you, or  on your  behalf to:  a)(i) place
orders for Shares  of the  Fund with  the Fund's  transfer agent  or direct  the
transfer  agent to receive instructions for the order of Shares, and (ii) accept
monies or direct that the transfer agent accept monies as payment for the  order
of  such Shares, all as contemplated by and  in accordance with Section 3 of the
Distribution Agreement; b)(i) place orders for  the redemption of Shares of  the
Fund  with the  Fund's transfer  agent or direct  the transfer  agent to receive
instruction for the redemption of Shares and (ii) to pay redemption proceeds  or
to  direct that  the transfer agent  pay redemption proceeds  in connection with
orders for the redemption  of Shares, all as  contemplated by and in  accordance
with  Section 4  of the  Distribution Agreement;  provided, however,  that in no
case, (i) is this indemnity 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 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 the Distribution
Agreement; or (ii) are you to be liable under the 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  you  in writing  within a
reasonable  time  after  the  summons  or  other  first  legal  process   giving
information  of  the  nature  of  the claim  shall  have  been  served  upon 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 you of any  such claim shall not relieve you from
any liability which  you may  have to  the person  against whom  such action  is
brought  otherwise than on account of  the indemnity agreement contained in this
paragraph. You  will be  entitled to  participate  at your  own expense  in  the
defense,  or, if  you so elect,  to assume the  defense, of any  suit brought to
enforce any such liability, but if you elect to assume the defense, such defense
shall be conducted by counsel chosen by you and satisfactory to the  Distributor
or  such controlling person or persons, defendant  or defendants in the suit. In
the event you  elect to  assume the  defense of any  such suit  and retain  such
counsel,  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 you do not elect to assume the defense of
any  such suit, you 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.  You  shall  promptly  notify the
Distributor of the commencement of any  litigation or proceedings against it  or
any  of its officers or directors in connection with the issuance or sale of the
Shares.
 
    II. If the indemnification provided for in this Section 10 is unavailable or
insufficient to hold harmless the Distributor,  as provided above in respect  of
any  losses, claims,  damages, liabilities  or expenses  (or actions  in respect
thereof) referred to  herein, then you  shall contribute to  the amount paid  or
payable  by  the  Distributor  as  a result  of  such  losses,  claims, damages,
liabilities or expenses (or actions in respect thereof) in such proportion as is
appropriate to reflect the relative benefits received by you on the one hand and
the
 
                                       2
<PAGE>
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 you shall contribute to such amount paid or payable by such
indemnified party in such proportion as is appropriate to reflect not only  such
relative  benefits but also your relative fault on the one hand and the relative
fault of 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. You  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 the  Distributor
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  the  Distributor  in  connection with
investigating or defending  any such  claim. Notwithstanding  the provisions  of
this  subsection (II),  you shall  not be required  to contribute  any amount in
excess of the amount by which the total price at which the Shares distributed by
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 Securities Act  of
1933  Act) shall be entitled to contribution  from any person who was not guilty
of such fraudulent misrepresentation.
 
    11. We  shall  have full  authority  to take  such  action as  we  may  deem
advisable  in  respect  of  all  matters  pertaining  to  the  distribution  and
redemption of Fund shares. We shall be under no liability to you except for lack
of good  faith and  for  obligations expressly  assumed  by us  herein.  Nothing
contained  in this paragraph  is intended to  operate as, and  the provisions of
this paragraph shall not in  any way whatsoever constitute,  a waiver by you  of
compliance  with any provision of the Securities  Act of 1933, as amended, or of
the rules  and regulations  of  the Securities  and Exchange  Commission  issued
thereunder.
 
    12.  You represent  that you  are a  member of  the National  Association of
Securities Dealers, Inc. and, with respect to any sales in the United States, we
both hereby agree to abide by the Rules of Fair Practice of such Association.
 
    13. Upon application to us, we will inform you as to the states in which  we
believe  the Shares have been  qualified for sale under,  or are exempt from the
requirements of, the respective securities laws of such states, but we assume no
responsibility  or  obligation  as  to  your   right  to  sell  Shares  in   any
jurisdiction.
 
    14.  All communications to us should be sent to the address shown below. Any
notice to you shall be duly given if mailed or telegraphed to you at the address
specified by you below.

Article 1      TERMS OF APPOINTMENT; DUTIES OF DWTC

               1.1  Subject to the terms and conditions set forth in this
Agreement, the Fund hereby employs and appoints DWTC to act as, and DWTC 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-

the Blue Sky or securities laws of any State or other jurisdiction is solely
limited to the initial establishment of transactions subject to Blue Sky
compliance by the Fund and the reporting of such transactions

                               SERVICES AGREEMENT

     AGREEMENT made as of the 31st day of December, 1993 by and between Dean
Witter InterCapital Inc., a Delaware corporation (herein referred to as
"InterCapital"), and Dean Witter Services Company Inc., a New Jersey corporation
(herein referred to as "DWS").

     WHEREAS, InterCapital has entered into separate agreements (each such
agreement being herein referred to as an "Investment Management Agreement") with
certain investment companies as set forth on Schedule A (each such investment
company being herein referred to as a "Fund" and, collectively, as the "Funds")
pursuant to which InterCapital is to perform, or supervise the performance of,
among other services, administrative services for the Funds (and, in the case of
Funds with multiple portfolios, the Series or Portfolios of the Funds (such
Series and Portfolio being herein individually referred to as "a Series" and,
collectively, as "the Series"));

     WHEREAS, InterCapital desires to retain DWS to perform the administrative
services as described below; and

     WHEREAS, DWS desires to be retained by InterCapital to perform such
administrative services:

     Now, therefore, in consideration of the mutual covenants and agreements of
the parties hereto as herein set forth, the parties covenant and agree as
follows:

     1.  DWS agrees to provide administrative services to each Fund as
hereinafter set forth. Without limiting the generality of the foregoing, DWS
shall (i) administer the Fund's business affairs and supervise the overall day-
to-day operations of the Fund (other than rendering investment advice); (ii)
provide the Fund with full administrative services, including the maintenance of
certain books and records, such as journals, ledger accounts and other records
required under the Investment Company Act of 1940, as amended (the"Act"), the
notification to the Fund and InterCapital of available funds for investment, the
reconciliation of account information and balances among the Fund's custodian,
transfer agent and dividend disbursing agent and InterCapital, and the
calculation of the net asset value of the Fund's shares; (iii) provide the Fund
with the services of persons competent to perform such supervisory,
administrative and clerical functions as are necessary to provide effective
operation of the Fund; (iv) oversee the performance of administrative and
professional services rendered to the Fund by others, including its custodian,
transfer agent and dividend disbursing agent, as well as accounting, auditing
and other services; (v) provide the Fund with adequate general office space and
facilities; (vi) assist in the preparation and the printing of the periodic
updating of the Fund's registration statement and prospectus (and, in the case
of an open-end Fund, the statement of additional information), tax returns,
proxy statements, and reports to its shareholders and the Securities and
Exchange Commission; and (vii) monitor the compliance of the Fund's investment
policies and restrictions.

     In the event that InterCapital enters into an Investment Management
Agreement with another investment company, and wishes to retain DWS to perform
administrative services hereunder, it shall notify DWS in writing. If DWS is
willing to render such services, it shall notify InterCapital in writing,
whereupon such other Fund shall become a Fund as defined herein.

     2. DWS shall, at its own expense, maintain such staff and employ or retain
such personnel and consult with such other persons as it shall from time to time
determine to be necessary or useful to the performance of its obligations under
this Agreement. Without limiting the generality of the foregoing, the staff and
personnel of DWS shall be deemed to include officers of DWS and persons employed
or otherwise retained by DWS (including officers and employees of InterCapital,
with the consent of InterCapital) to furnish services, statistical and other
factual data, information with respect to technical and scientific developments,
and such other information, advice and assistance as DWS may desire. DWS shall
maintain each Fund's records and books of account (other than those maintained
by the Fund's transfer agent, registrar, custodian and other agencies). All such
books and records so maintained shall be the property of the Fund and, upon
request therefor, DWS shall surrender to InterCapital or to the Fund such of the
books and records so requested.

     3. InterCapital will, from time to time, furnish or otherwise make
available to DWS such financial reports, proxy statements and other information
relating to the business and affairs of the Fund as DWS may

                                        1

<PAGE>

reasonably require in order to discharge its duties and obligations to the Fund
under this Agreement or to comply with any applicable law and regulation or
request of the Board of Directors/Trustees of the Fund.

     4. For the services to be rendered, the facilities furnished, and the
expenses assumed by DWS, InterCapital shall pay to DWS monthly compensation
calculated daily (in the case of an open-end Fund) or weekly (in the case of a
closed-end Fund) by applying the annual rate or rates set forth on Schedule B to
the net assets of each Fund. Except as hereinafter set forth, (i) in the case of
an open-end Fund, compensation under this Agreement shall be calculated by
applying 1/365th of the annual rate or rates to the Fund's or the Series' daily
net assets determined as of the close of business on that day or the last
previous business day and (ii) in the case of a closed-end Fund, compensation
under this Agreement shall be calculated by applying the annual rate or rates to
the Fund's average weekly net assets determined as of the close of the last
business day of each week. 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 on
Schedule B. Subject to the provisions of paragraph 5 hereof, payment of DWS'
compensation for the preceding month shall be made as promptly as possible after
completion of the computations contemplated by paragraph 5 hereof.

     5. In the event the operating expenses of any open-end Fund and/or any
Series thereof, or of InterCapital Income Securities Inc., including amounts
payable to InterCapital pursuant to the Investment Management Agreement, for any
fiscal year ending on a date on which this Agreement is in effect, exceed the
expense limitations applicable to the Fund and/or any Series thereof imposed by
state securities laws or regulations thereunder, as such limitations may be
raised or lowered from time to time, or, in the case of InterCapital Income
Securities Inc. or Dean Witter Variable Investment Series or any Series thereof,
the expense limitation specified in the Fund's Investment Management Agreement,
the fee payable hereunder shall be reduced on a pro rata basis in the same
proportion as the fee payable by the Fund under the Investment Management
Agreement is reduced.

     6. DWS shall bear the cost of rendering the administrative services to be
performed by it under this Agreement, and shall, at its own expense, pay the
compensation of the officers and employees, if any, of the Fund employed by DWS,
and such clerical help and bookkeeping services as DWS shall reasonably require
in performing its duties hereunder.

     7. DWS will use its best efforts in the performance of administrative
activities on behalf of each Fund, but in the absence of willful misfeasance,
bad faith, gross negligence or reckless disregard of its obligations hereunder,
DWS 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 DWS or for any losses
sustained by the Fund or its investors. It is understood that, subject to the
terms and conditions of the Investment Management Agreement between each Fund
and InterCapital, InterCapital shall retain ultimate responsibility for all
services to be performed hereunder by DWS. DWS shall indemnify InterCapital and
hold it harmless from any liability that InterCapital may incur arising out of
any act or failure to act by DWS in carrying out its responsibilities hereunder.

     8. It is understood that any of the shareholders, Directors/Trustees,
officers and employees of the Fund may be a shareholder, director, officer or
employee of, or be otherwise interested in, DWS, and in any person controlling,
controlled by or under common control with DWS, and that DWS and any person
controlling, controlled by or under common control with DWS may have an interest
in the Fund. It is also understood that DWS and any affiliated persons thereof
or any persons controlling, controlled by or under common control with DWS have
and may have advisory, management, administration service or other contracts
with other organizations and persons, and may have other interests and
businesses, and further may purchase, sell or trade any securities or
commodities for their own accounts or for the account of others for whom they
may be acting.

     9. This Agreement shall continue until April 30, 1994, and thereafter shall
continue automatically for successive periods of one year unless terminated by
either party by written notice delivered to the other party within 30 days of
the expiration of the then-existing period. Notwithstanding the foregoing, this
Agreement may be terminated at any time, by either party on 30 days' written
notice delivered to the other party. In the

                                        2

<PAGE>

event that the Investment Management Agreement between any Fund and InterCapital
is terminated, this Agreement will automatically terminate with respect to such
Fund.

     10. This Agreement may be amended or modified by the parties in any manner
by mutual written agreement executed by each of the parties hereto.

     11. This Agreement shall be construed and interpreted in accordance with
the laws of the State of New York.

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

        AMENDED AND RESTATED PLAN OF DISTRIBUTION PURSUANT TO RULE 12B-1
                                       OF
            DEAN WITTER/SEARS NEW YORK MUNICIPAL MONEY MARKET TRUST
 
    WHEREAS,  Dean  Witter/Sears  New  York Municipal  Money  Market  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  March  5,  1990, the  Fund  adopted  a Plan  and  Agreement  of
Distribution  pursuant  to  Rule 12b-1  under  the  Act, and  the  Trustees then
determined that there was a reasonable likelihood that the Plan of  Distribution
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  Plan  and  Agreement  of
Distribution was  entered  into by  the  Fund  with Dean  Witter  Reynolds  Inc.
("DWR"); and
 
    WHEREAS,  the Fund  and DWR desire  to substitute DW  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 this date,  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 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 Board of 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 Board of
Trustees determines 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 in such amounts determined in advance
of each fiscal quarter by the Fund's Board of Trustees, including a majority  of
the  Trustees who are  not "interested persons"  of the Fund,  as defined in the
Act. 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 making quarterly determinations of the amounts that may  be
expended  by the  Fund, the  Distributor shall  provide, and  the Trustees shall
 
                                       1
<PAGE>
review, a quarterly budget of projected incremental distribution expenses to  be
incurred  by the  Distributor, DWR, its  affiliates and  other broker-dealers on
behalf of  the  Fund,  together  with  a  report  explaining  the  purposes  and
anticipated  benefits of  incurring such expenses.  The Board  of 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 fiscal 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 fiscal 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 fiscal
year.
 
    7.    The Distributor  shall provide  the Fund  for review  by the  Board of
Trustees, and the Board of Trustees shall review, promptly after the end of each
fiscal 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  fiscal 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 Board of 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, 1993, 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 30 days' written notice to any other party to this Plan.
 
    11. While this Plan is in  effect, the selection and nomination of  Trustees
who  are not interested persons of the Fund shall be committed to the discretion
of the Trustees who are not interested persons.
 
    12. The  Fund  shall preserve  copies  of this  Plan  and all  reports  made
pursuant to paragraph 7 hereof, for a period of not less than six years from the
date  of this Plan, as  amended and restated herein, or  any such report, as the
case may be, the first two years in an easily accessible place.
 
    13. This Plan shall be construed in accordance with the laws 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, conflict with the
applicable provisions of the Act, the latter shall control.
 
    14.  The  Declaration  of  Trust  establishing  Dean  Witter/Sears  New York
Municipal Money Market Trust, dated December 28, 1989, 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/Sears  New York Municipal Money Market Trust refers to the Trustees under
the Declaration collectively as Trustees, but not as individuals or  personally;
and no Trustee, shareholder, officer, employee or agent of Dean Witter/Sears New
 
                                       2
<PAGE>
York  Municipal Money Market Trust shall be  held to any personal liability, nor
shall resort  be had  to their  private  property for  the satisfaction  of  any
obligation  or claim or otherwise,  in connection with the  affairs of said Dean
Witter/Sears New York Municipal  Money Market Trust, but  the Trust Estate  only
shall be liable.
 
    IN  WITNESS WHEREOF,  the Fund, the  Distributor and DWR  have executed this
Plan of Distribution, as amended and restated, as of the day and year set  forth
below in New York, New York.
