              Dean Witter New York Tax-Free Income Fund (the "Fund") is an
open-end, diversified management investment company whose investment objective
is to provide a high level of current income exempt from federal, New York State
and New York City income tax, consistent with the preservation of capital. The
Fund invests principally in New York tax-exempt fixed-income securities which
are rated in the four highest categories by Moody's Investors Service, Inc. or
Standard & Poor's Corporation. (See "Investment Objective and Policies.")
 
               Shares of the Fund are continuously offered at net asset value
without the imposition of a sales charge. However, redemptions and/or
repurchases are subject in most cases to a contingent deferred sales charge,
scaled down from 5% to 1% of the amount redeemed, if made within six years of
purchase, which charge will be paid to the Fund's Distributor, Dean Witter
Distributors Inc. See "Redemptions and Repurchases--Contingent Deferred Sales
Charge." In addition, the Fund pays the Distributor a distribution fee pursuant
to a Plan of Distribution pursuant to Rule 12b-1 under the Investment Company
Act of 1940 at the annual rate of 0.75% of the lesser of the (i) average daily
aggregate net sales or (ii) average daily net assets of the Fund. See "Purchases
of Fund Shares--Plan of Distribution."

PROSPECTUS SUMMARY
- --------------------------------------------------------------------------------
 
   
<TABLE>
<S>                 <C>
The                 The Fund is organized as a Trust, commonly known as a Massachusetts business trust, and is an open-end,
Fund                diversified management investment company investing principally in New York tax-exempt fixed-income securities
                    which are rated in the four highest categories by Moody's Investors Service Inc. or Standard and Poor's
                    Corporation (see page 5).
- ------------------------------------------------------------------------------------------------------------------------------------
Shares Offered      Shares of beneficial interest with $0.01 par value (see page 21).
- ------------------------------------------------------------------------------------------------------------------------------------
Offering            At net asset value without sales charge (see page 12). Shares redeemed within six years of purchase are subject
Price               to a contingent deferred sales charge under most circumstances (see page 16).
- ------------------------------------------------------------------------------------------------------------------------------------
Minimum             Minimum initial investment, $1,000 ($100 if the account is opened through EasyInvest-SM-); minimum subsequent
Purchase            investment, $100 (see page 12).
- ------------------------------------------------------------------------------------------------------------------------------------
Investment          The investment objective of the Fund is to provide a high level of current income exempt from federal, New York
Objective           State and New York City income tax, consistent with preservation of capital.
- ------------------------------------------------------------------------------------------------------------------------------------
Investment          The Fund will invest principally in New York tax-exempt fixed-income securities. However, it may also invest in
Policies            taxable money market instruments, non-New York tax-exempt securities, futures and options.
- ------------------------------------------------------------------------------------------------------------------------------------
Investment          Dean Witter InterCapital Inc., the Investment Manager of the Fund, and its wholly-owned subsidiary, Dean Witter
Manager             Services Company Inc., serve in various investment management, advisory, management and administrative
                    capacities to 102 investment companies and other portfolios with assets of approximately $93 billion at February
                    28, 1997 (see page 5).
- ------------------------------------------------------------------------------------------------------------------------------------
Management          The Investment Manager receives a monthly fee at the annual rate of 0.55 of 1% of daily net assets, scaled down
Fee                 on assets over $500 million. The fee should not be compared with fees paid by other investment companies without
                    also considering applicable sales loads and distribution fees, including those noted below.
- ------------------------------------------------------------------------------------------------------------------------------------
Dividends           Dividends are declared daily, and either paid monthly as additional shares of the Fund or, at the shareholder's
                    option, paid monthly in cash (see page 19).
- ------------------------------------------------------------------------------------------------------------------------------------
Distributor and     Dean Witter Distributors Inc. (the "Distributor"). The Distributor receives from the Fund, pursuant to a Rule
Distribution Fee    12b-1 Plan of Distribution, a distribution fee accrued daily and payable monthly at the rate of 0.75% per annum
                    of the lesser of (i) the Fund's average daily aggregate net sales or (ii) the Fund's average daily net assets.
                    This fee compensates the Distributor for the services provided in distributing shares of the Fund and for its
                    sales-related expenses. The Distributor also receives the proceeds of any contingent deferred sales charges (see
                    pages 13).
- ------------------------------------------------------------------------------------------------------------------------------------
Redemption          At net asset value; redeemable involuntarily if the total value of the account is less than $100, or, if the
                    account was opened through EasyInvest-SM-, if after twelve months the shareholder has invested less than $1,000
                    in the account. (see page 18). Redemptions within six years of purchase are subject to a contingent deferred
                    sales charge under most circumstances (see page 17).
- ------------------------------------------------------------------------------------------------------------------------------------
Contingent          Although no commission or sales charge is imposed upon the purchase of shares, a contingent deferred sales
Deferred Sales      charge (scaled down from 5% to 1%) is imposed on any redemption of shares if, after such redemption, the
Charge              aggregate current value of an account with the Fund falls below the aggregate amount of the investor's purchase
                    payments made during the six years preceding the redemption. However, there is no charge imposed on redemption
                    of shares purchased through reinvestment of dividends or distributions (see pages 17-19).
- ------------------------------------------------------------------------------------------------------------------------------------
Risks               The value of the Fund's portfolio securities, and therefore the Fund's net asset value per share, may increase
                    or decrease due to various factors, principally changes in prevailing interest rates and the ability of the
                    issuers of the Fund's portfolio securities to pay interest and principal on such obligations. The Fund also may
                    invest in futures and options for portfolio hedging purposes. Futures and options may be considered speculative
                    in nature and may involve greater risks than those customarily assumed by certain other investment companies
                    which do not invest in such instruments. 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 issuers to pay interest or repay principal (see pages 7-11).

THE FUND AND ITS MANAGEMENT
- --------------------------------------------------------------------------------
 
    Dean Witter  New York  Tax-Free Income  Fund (the  "Fund") is  an  open-end,
diversified  management  investment company.  The Fund  is a  trust of  the type
commonly known as a "Massachusetts business  trust" and was organized under  the
laws of Massachusetts on January 17, 1985.
 
    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 102  investment companies,  thirty of
which are listed  on the  New York Stock  Exchange, with  combined total  assets
including  this Fund of approximately $89.8 billion as of February 28, 1997. The
Investment Manager also manages portfolios of pension plans, other  institutions
and individuals which aggregated approximately $3.2 billion at such date.
    
 
   
    On  February 5, 1997, DWDC and Morgan Stanley Group Inc. announced that they
had entered into an Agreement and Plan  of Merger, with the combined company  to
be  named Morgan  Stanley, Dean  Witter, Discover &  Co. The  business of Morgan
Stanley Group Inc.  and its affiliated  companies is providing  a wide range  of
financial  services  for sovereign  governments, corporations,  institutions and
individuals throughout the world. DWDC is the direct parent of InterCapital  and
Dean   Witter  Distributors  Inc.,  the  Fund's  distributor.  It  is  currently
anticipated  that   the  transaction   will  close   in  mid-1997.   Thereafter,
InterCapital  and Dean Witter  Distributors Inc. will  be direct subsidiaries of
Morgan Stanley, Dean Witter, Discover & Co.
    
 
    The Fund  has  retained the  Investment  Manager to  provide  administrative
services,  manage its business  affairs and manage the  investment of the Fund's
assets, including the placing of orders  for the purchase and sale of  portfolio
securities.  InterCapital  has retained  Dean  Witter Services  Company  Inc. to
perform the  aforementioned administrative  services for  the Fund.  The  Fund's
Board  of  Trustees  reviews  the  various services  provided  by  or  under the
direction of the Investment Manager to ensure that the Fund's general investment
policies and programs  are being  properly carried out  and that  administrative
services are being provided to the Fund in a satisfactory manner.
 
   
    As  full compensation for the services  and facilities furnished to the Fund
and for expenses of the  Fund assumed by the  Investment Manager, the Fund  pays
the  Investment Manager  monthly compensation  calculated daily  by applying the
following annual rates to the net assets of the Fund determined as of the  close
of each business day: 0.55% of the portion of the daily net assets not exceeding
$500  million and 0.525% of  the portion of the  daily net assets exceeding $500
million. For the  fiscal year ended  December 31, 1996,  the Fund accrued  total
compensation  to the Investment Manager amounting to 0.55% of the Fund's average
daily net assets and the Fund's total  expenses amounted to 1.41% of the  Fund's
average daily net assets.
    
 
INVESTMENT OBJECTIVE AND POLICIES
- --------------------------------------------------------------------------------
 
    The  investment objective of the Fund is  to provide a high level of current
income which is exempt  from federal, New  York State and  New York City  income
tax,  consistent with  the preservation of  capital. There is  no assurance that
this objective  will be  achieved.  The Fund  seeks  to achieve  its  investment
objective by investing its assets in accordance with the following policies:
 
                                       5
<PAGE>
   1.  As a  fundamental policy  the Fund must  have at  least 80%  of its total
assets invested in New York tax-exempt securities, except as stated in paragraph
(3) below. New  York tax-exempt securities  consist of obligations  of New  York
State,  its political subdivisions, authorities and corporations, as well as any
debt obligations (certain governmental entities  and territories such as  Puerto
Rico, Guam and the Virgin Islands) that generate interest income which is exempt
from federal, New York State and New York City income taxes. New York tax-exempt
securities   consist  of   Municipal  Bonds  and   Municipal  Notes  ("Municipal
Obligations")  and  Municipal  Commercial   Paper.  Only  New  York   tax-exempt
securities  which satisfy the following standards  may be purchased by the Fund:
(a) Municipal Bonds  which are rated  at the  time of purchase  within the  four
highest  grades by  Moody's Investors  Service, Inc.  ("Moody's") or  Standard &
Poor's Corporation ("S&P"); (b) Municipal Notes of issuers which at the time  of
purchase  are rated  in the  two highest grades  by Moody's  or S&P,  or, if not
rated, have outstanding one or more issues of Municipal Bonds rated as set forth
in clause (a)  of this paragraph;  (c) Municipal Commercial  Paper which at  the
time  of  purchase is  rated  P-1 by  Moody's  or A-1  by  S&P; and  (d) unrated
securities which at the time of purchase are judged by the Investment Manager to
be of comparable quality to the securities described above. For a description of
Moody's and  S&P's ratings,  see the  Appendix to  the Statement  of  Additional
Information.
 
   
   2. In accordance with the current position of the staff of the Securities and
Exchange  Commission,  tax-exempt securities  which are  subject to  the federal
alternative minimum tax for individual shareholders ("AMT") will not be included
in the 80% total described in paragraph 1 above. (See "Dividends,  Distributions
and  Taxes," page 19.) As such, the remaining portion of the Fund's total assets
may be invested in tax-exempt securities subject to the AMT.
    
 
   3. Up to  20% of the  Fund's total assets  may be invested  in taxable  money
market  instruments, non-New York tax-exempt securities, futures and options and
tax-exempt securities  subject to  the AMT.  However, the  Fund may  temporarily
invest  more than 20% of  its total assets in  taxable money market instruments,
non-New York tax-exempt securities and tax-exempt securities subject to the AMT,
in order  to  maintain  a  "defensive"  posture when,  in  the  opinion  of  the
Investment  Manager, it is advisable to do so because of market conditions. Only
those non-New York tax-exempt securities  which satisfy the standards set  forth
in  paragraph (1)  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 or higher by Moody's or A-1 or higher by 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.
 
    Municipal   Obligations  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 is a short-term obligation of a
municipality. Any Municipal Obligation which  depends directly or indirectly  on
the credit of the Federal Government, its agencies or instrumentalities shall be
considered  to have a rating of Aaa/AAA. An obligation shall be considered a New
York tax-exempt security only if, in  the opinion of bond counsel, the  interest
payable  thereon is exempt from federal, New York State and New York City income
tax. The Fund may also purchase Municipal Obligations which had originally  been
issued  by  the  same issuer  as  two separate  series  of the  same  issue with
different interest rates, but which are now linked together to form one series.
 
    The two principal  classifications of Municipal  Obligations 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
 
                                       6
<PAGE>
pledge  of its faith, credit  and taxing power for  the payment of principal and
interest. Issuers of general obligation bonds, notes or commercial paper include
a state,  its counties,  cities,  towns and  other governmental  units.  Revenue
bonds,  notes or commercial paper  are payable from the  revenues derived from a
particular facility or  class of  facilities or,  in some  cases, from  specific
revenue  sources. Revenue bonds, notes or commercial paper are issued for a wide
variety of purposes, including the financing  of electric, gas, water and  sewer
systems and other public utilities; industrial development and pollution control
facilities;   single  and  multi-family  housing  units;  public  buildings  and
facilities; air and marine ports; transportation facilities such as toll  roads,
bridges and tunnels; and health and educational facilities such as hospitals and
dormitories.  They rely primarily on user fees to pay debt service, although the
principal revenue source is often  supplemented by additional security  features
which  are intended to enhance the creditworthiness of the issuer's obligations.
In some cases, particularly revenue bonds  issued to finance housing and  public
buildings,  a direct or implied "moral obligation" of a governmental unit may be
pledged to the payment of debt service.  In other cases, a special tax or  other
charge may augment user fees.
 
RISK CONSIDERATIONS
 
    Investments  in municipal bonds  rated either Baa  by Moody's or  BBB by S&P
(investment grade bonds--the lowest rated  permissible investments by the  Fund)
may  have  speculative  characteristics  and,  therefore,  changes  in  economic
conditions or other circumstances  are more likely to  weaken their capacity  to
make  principal and interest payments than would be the case with investments in
securities with higher credit ratings.
 
    Included  within  the  revenue  category   of  bonds  described  above   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 type of financing that may not have 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 value of the Fund's portfolio  securities, and therefore the Fund's  net
asset  value  per  share,  may  increase or  decrease  due  to  various factors,
princi-
 
                                       7
<PAGE>
pally changes in prevailing interest rates and the ability of the issuers of the
Fund's portfolio securities to pay interest and principal on such obligations on
a timely basis. Generally a rise in interest rates will result in a decrease  in
the Fund's net asset value per share, while a drop in interest rates will result
in an increase in the Fund's net asset value per share.
 
    VARIABLE RATE OBLIGATIONS.  The interest rates payable on certain securities
in  which the Fund may invest are not fixed and may fluctuate based upon changes
in  market  rates.  Obligations  of   this  type  are  called  "variable   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  AND FORWARD COMMITMENTS.   From
time  to  time,  in the  ordinary  course  of business,  the  Fund  may purchase
securities on a when-issued or delayed  delivery basis, or may purchase or  sell
securities on a forward commitment basis. When such transactions are negotiated,
the  price is fixed at the time of  the commitment, but delivery and payment can
take place a month or more after the date of the commitment. There is no overall
limit on the  percentage of  the Fund's  assets which  may be  committed to  the
purchase  of securities on a when-issued, delayed delivery or forward commitment
basis. An  increase in  the percentage  of the  Fund's assets  committed to  the
purchase  of securities on a when-issued, delayed delivery or forward commitment
basis may increase the volatility of the Fund's net asset value.
 
    ZERO COUPON SECURITIES.  A portion of the fixed-income securities  purchased
by  the Fund may be  zero coupon securities. Such  securities are purchased at a
discount from their face amount, giving the purchaser the right to receive their
full value at maturity. The interest  earned on such securities is,  implicitly,
automatically  compounded and paid out at  maturity. While such compounding at a
constant rate eliminates the risk of receiving lower yields upon reinvestment of
interest if  prevailing interest  rates  decline, the  owner  of a  zero  coupon
security  will be  unable to participate  in higher yields  upon reinvestment of
interest received  on interest-paying  securities if  prevailing interest  rates
rise.
 
    A  zero coupon  security pays  no interest  to its  holder during  its life.
Therefore, to the extent the Fund invests in zero coupon securities, it will not
receive current cash  available for distribution  to shareholders. In  addition,
zero  coupon securities are subject  to substantially greater price fluctuations
during periods  of  changing  prevailing  interest  rates  than  are  comparable
securities  which  pay interest  on  a current  basis.  Current federal  tax law
requires that a holder  (such as the  Fund) of a zero  coupon security accrue  a
portion  of the discount at which the security was purchased as income each year
even though  the Fund  receives no  interest payments  in cash  on the  security
during the year.
 
   
    The Fund may enter into financial futures contracts, options on such futures
and municipal bond index futures contracts for hedging purposes.
    
 
    FINANCIAL  FUTURES CONTRACTS AND OPTIONS ON FUTURES.  The Fund may invest in
financial futures contracts  and related options  thereon. The Fund  may sell  a
financial  futures contract, or purchase a  put option on such futures contract,
if the Investment Manager anticipates interest rates to rise, as a hedge against
a decrease in the  value of the Fund's  portfolio securities. If the  Investment
Manager  anticipates that interest  rates will decline, the  Fund may purchase a
financial futures  contract or  a  call option  thereon  to protect  against  an
increase  in the  price of  the securities the  Fund intends  to purchase. These
futures contracts  and related  options thereon  will be  used only  as a  hedge
against  anticipated interest rate  changes. A futures  contract sale creates an
obligation by the Fund,  as seller, to deliver  the specific type of  instrument
called  for in the contract at a specified  future time for a specified price. A
futures contract purchase would create an obligation by the Fund, as  purchaser,
to  take delivery of  the specific type  of financial instrument  at a specified
future time at a  specified price. The specific  securities delivered or  taken,
respectively,  at settlement  date, would not  be determined until  or near that
date. The
determi-
 
                                       8
<PAGE>
nation would  be in  accordance with  the rules  of the  exchange on  which  the
futures contract sale or purchase was effected.
 
    Although the terms of financial futures contracts specify actual delivery or
receipt of securities, in most instances the contracts are closed out before the
settlement  date without  the making  or taking  of delivery  of the securities.
Closing out of  a futures contract  is effected by  entering into an  offsetting
purchase or sale transaction.
 
    Unlike  a financial futures contract, which  requires the parties to buy and
sell a security on a set date, an option on such a futures contract entitles its
holder to  decide on  or before  a  future date  whether to  enter into  such  a
contract  (a long position in the case of  a call option and a short position in
the case of a put option). If the holder decides not to enter into the contract,
the premium paid for the option on the contract is lost. Since the value of  the
option  is fixed at  the point of sale,  there are no daily  payments of cash to
reflect the change  in the value  of the underlying  contract as there  is by  a
purchaser  or seller of a futures contract.  The value of the option does change
and is reflected in the net asset value of the Fund.
 
    A risk in employing financial futures contracts to protect against the price
volatility of portfolio securities is that  the prices of securities subject  to
futures contracts may correlate imperfectly with the behavior of the cash prices
of  the Fund's portfolio  securities. The risk of  imperfect correlation will be
increased by the  fact that financial  futures contracts in  which the Fund  may
invest are on taxable securities rather than on tax-exempt securities, and there
is  no guarantee that  the prices of  taxable securities will  move in a similar
manner to the prices of tax-exempt securities. The correlation may be  distorted
by  the fact that the futures market  is dominated by short-term traders seeking
to profit from the difference between a contract or security price objective and
their cost of  borrowed funds. Such  distortions are generally  minor and  would
diminish as the contract approached maturity.
 
    Another  risk  is  that  the  Fund's  manager  could  be  incorrect  in  his
expectations as to the direction or extent of various interest rate movements or
the time span within which  the movements take place.  For example, if the  Fund
sold  financial futures contracts for the  sale of securities in anticipation of
an increase  in interest  rates,  and then  interest  rates went  down  instead,
causing bond prices to rise, the Fund would lose money on the sale.
 
    In  addition to the  risks that apply  to all options  transactions (see the
Statement of Additional Information for a description of the characteristics of,
and the risks of  investing in, options on  debt securities), there are  several
special  risks relating  to options  on futures;  in particular,  the ability to
establish and  close  out positions  on  such options  will  be subject  to  the
development and maintenance of a liquid secondary market. It is not certain that
this market will develop or be maintained.
 
    MUNICIPAL  BOND INDEX  FUTURES.  The  Fund may utilize  municipal bond index
futures contracts for hedging purposes. The Fund's strategies in employing  such
contracts  will be  similar to  that discussed  above with  respect to financial
futures and options thereon. A municipal bond index is a method of reflecting in
a single  number the  market value  of  many different  municipal bonds  and  is
designed  to be representative of the municipal bond market generally. The index
fluctuates in response  to changes in  the market values  of the bonds  included
within  the index. Unlike futures contracts on particular financial instruments,
transactions in futures on a  municipal bond index will  be settled in cash,  if
held until the close of trading in the contract. However, like any other futures
contract, a position in the contract may be closed out by purchase or sale of an
offsetting  contract  for the  same delivery  month prior  to expiration  of the
contract.
 
    The Fund may not enter into futures contracts or related options thereon  if
immediately  thereafter the amount committed to  margin plus the amount paid for
option premiums exceeds 5% of the value of the Fund's total assets. The Fund may
not   purchase   or   sell   futures    contracts   or   related   options    if
 
                                       9

immediately thereafter more than one-third of its net assets would be hedged.
 
   
    Except as specified, the investment policies noted above are not fundamental
policies and may be changed without shareholder approval.
    
 
RISK 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  (the "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 York  City  (the "City")  or any  of the
Agencies or Authorities suffers serious  financial difficulty, both the  ability
of the State, the 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.
 
   
    Over the long term, the State and City face potential economic problems. The
City accounts for a large portion of the State's population and personal income,
and the City's  financial health affects  the State in  numerous ways. The  City
continues  to require significant financial assistance  from the State. The City
depends on State aid both to enable the  City to balance its budget and to  meet
its  cash requirements. The State  could also be affected  by the ability of the
City to market its securities successfully in the public credit markets.
    
 
   
    The economic and financial  condition of the State  also may be affected  by
various  financial, social, economic and political  factors. Such factors can be
very complex, may vary from  fiscal year to fiscal  year and are frequently  the
result   of  actions  taken  not  only  by   the  State  and  its  agencies  and
instrumentalities, but also by  entities, such as  the Federal government,  that
are not under the control of the State.
    
 
   
    On  January 13, 1992, Standard  & Poor's reduced its  ratings on the State's
general obligation bonds from A to A-  and, in addition, reduced its ratings  on
the  State's  moral  obligation,  lease  purchase,  guaranteed  and  contractual
obligation debt. Standard &  Poor's also continued  its negative rating  outlook
assessment  on  State general  obligation debt.  On April  26, 1993,  Standard &
Poor's revised the rating  outlook assessment to stable.  On February 14,  1994,
Standard  &  Poor's raised  its  outlook to  positive  and, on  August  5, 1996,
confirmed its A-  rating. On  January 6, 1992,  Moody's reduced  its ratings  on
outstanding  limited-liability State lease  purchase and contractual obligations
from A  to Baa1.  On July  26, 1996,  Moody's reconfirmed  its A  rating on  the
State's general obligation long-term indebtedness.
    
 
    For  a  more detailed  discussion  of the  risks  of investing  in  New York
tax-exempt securities, see the Statement of Additional Information.
 
    The summary information furnished above  and in the Statement of  Additional
Information  is based on official statements prepared  by the State and the City
in connection with their  borrowings and contains such  information as the  Fund
deems  relevant in considering an investment in the Fund. It does not purport to
be a complete description of the considerations contained therein. The  official
statements  relied on are dated  January 24, 1996 with  respect to the State and
December 21,  1995 with  respect to  the City,  and the  information therein  is
subject to change after such dates.
 
PORTFOLIO MANAGEMENT
 
    The  Fund is managed by the Investment  Manager with a view to achieving its
investment
objec-
 
                                       10
<PAGE>
   
tive. In determining which securities  to purchase for the  Fund or hold in  the
Fund's  portfolio, the Investment Manager will  rely on information from various
sources, including research,  analysis and  appraisals of  brokers and  dealers,
including  Dean  Witter  Reynolds  Inc. ("DWR"),  a  broker-dealer  affiliate of
InterCapital; the views of  Trustees of the Fund  and others regarding  economic
developments and interest rate trends; and the Investment Manager's own analysis
of  factors  it  deems  relevant.  The  Fund  is  managed  within InterCapital's
Tax-Exempt  Group,  which  manages  40  tax-exempt  municipal  funds  and   fund
portfolios,  with approximately $10.8 billion in  assets as of January 30, 1997.
James F.  Willison,  Senior  Vice  President  of  InterCapital  and  Manager  of
InterCapital's  Municipal  Fixed-Income  Group,  and  Joseph  R.  Arcieri,  Vice
President of InterCapital and a member of InterCapital's Municipal  Fixed-Income
Group,  have  been  the primary  portfolio  co-managers  of the  Fund  since its
inception and February, 1997, respectively, and have been portfolio managers  at
InterCapital for over five years.
    
 
    Securities  are purchased and sold principally in response to the Investment
Manager's current evaluation of an issuer's ability to meet its debt obligations
in the future, and the Investment Manager's current assessment of future changes
in the levels of interest rates on tax-exempt securities of varying  maturities,
qualities  and purpose. Securities purchased by the Fund are, generally, sold by
dealers acting as principal for their own accounts.
 
   
    Pursuant to an order issued by  the Securities and Exchange Commission,  the
Fund   may  effect  principal  transactions  in  certain  taxable  money  market
instruments with DWR. In addition, the  Fund may incur brokerage commissions  on
transactions conducted through DWR.
    
 
INVESTMENT RESTRICTIONS
- --------------------------------------------------------------------------------
 
    The  investment restrictions  listed below  are among  the restrictions that
have been adopted  by the  Fund as  fundamental policies.  Under the  Investment
Company  Act of 1940,  as amended (the  "Act"), a fundamental  policy may not be
changed without the vote of a  majority of the outstanding voting securities  of
the Fund, as defined in the Act.
 
    The Fund may not:
 
   1. With respect to 75% of its total assets, purchase securities of any issuer
if  immediately thereafter  more than  5% of  the Fund's  total assets  would be
invested in  securities  of  such  issuer  (other  than  obligations  issued  or
guaranteed by the United States Government, its agencies or instrumentalities or
by the State of New York or its political subdivisions).
 
   2.  Purchase more than 10% of all  outstanding taxable debt securities of any
one issuer (other  than obligations issued,  or guaranteed as  to principal  and
interest, by the United States Government, its agencies or instrumentalities).
 
   
   3.  Invest more than  25% of the value  of its total  assets in securities of
issuers in any  one industry.  This restriction  does not  apply to  obligations
issued   or  guaranteed  by  the  United  States  Government,  its  agencies  or
instrumentalities, or  issued  by  the  State  of  New  York  or  its  political
subdivisions  (industrial development  and pollution  control bonds  are grouped
into industries based upon the business in which the issuers of such obligations
are engaged).
    
 
PURCHASE OF FUND SHARES
- --------------------------------------------------------------------------------
 
    The Fund offers its  shares for sale  to the public  on a continuous  basis.
Shares  of  the  Fund are  distributed  by  Dean Witter  Distributors  Inc. (the
"Distributor"),  an  affiliate  of  the   Investment  Manager,  pursuant  to   a
Distribution  Agreement between the Fund and  the Distributor and are 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.
 
                                       11
<PAGE>
   
    The minimum initial purchase is $1,000. Subsequent purchases of $100 or more
may be made by sending a check, payable to Dean Witter New York Tax-Free  Income
Fund, directly to Dean Witter Trust Company ("Transfer Agent") at P.O. Box 1040,
Jersey  City,  New Jersey  07303  or by  contacting  a DWR  or  another Selected
Broker-Dealer account executive.  The minimum  initial purchase in  the case  of
investments through EasyInvest-SM-, an automatic purchase plan (see "Shareholder
Services"),  is $100, provided  that the schedule  of automatic investments will
result in investments totalling at least $1,000 within the first twelve  months.
Certificates for shares purchased will not be issued unless a request is made by
the  shareholder in writing to  the Transfer Agent. Shares  are sold through the
Distributor on a normal  three business day settlement  basis; that is,  payment
generally is due on or before the third business day (settlement date) after the
order  is placed with the Distributor. Shares  of the Fund purchased through the
Distributor or a Selected Broker-Dealer  are entitled to dividends beginning  on
the  next business day  following settlement date. Since  DWR and other Selected
Broker-Dealers forward investors'  funds on settlement  date, they will  benefit
from  the temporary use of the funds  when payment is made prior thereto. Shares
purchased through the Transfer Agent are entitled to dividends beginning on  the
next  business day following receipt of an  order. As noted above, orders placed
directly with the Transfer Agent must be accompanied by payment. Investors  will
be entitled to receive capital gains distributions if their order is received by
the   close  of  business  on  the  day  prior  to  the  record  date  for  such
distributions. The offering  price will be  the net asset  value per share  next
determined following receipt of an order (see "Determination of Net Asset Value"
below).  While no sales  charge is imposed  at the time  shares are purchased, a
contingent deferred sales charge may be  imposed at the time of redemption  (see
"Redemptions  and  Repurchases"). Sales  personnel  are compensated  for selling
shares of the Fund at the time of their sale by the Distributor and/or  Selected
Broker-Dealer.  In addition, some sales  personnel of the Selected Broker-Dealer
will receive various types of non-cash compensation as special sales incentives,
including trips, educational and/or business seminars and merchandise. The  Fund
and the Distributor reserve the right to reject any purchase orders.
    
 
    ANALOGOUS  DEAN WITTER  FUNDS.  The  Distributor and  the Investment Manager
serve in  the  same capacities  for  Dean Witter  Multi-State  Municipal  Series
Trust-New York Series, an open-end investment company with investment objectives
and  policies similar to those of the  Fund. Unlike the Fund, however, shares of
Dean Witter Multi-State Municipal  Series Trust-New York  Series are offered  to
the  public with a sales  charge imposed at the time  of purchase, rather than a
contingent deferred sales charge assessed  upon redemptions within six years  of
purchase.  These two Dean  Witter Funds have differing  fees and expenses, which
will affect performance. Investors  who would like to  receive a prospectus  for
Dean  Witter Multi-State Municipal Series Trust-New  York Series should call the
telephone numbers listed  on the  front cover of  this Prospectus,  or may  call
their account executive for additional information.
 
PLAN OF DISTRIBUTION
 
    The  Fund has adopted a Plan of  Distribution, pursuant to Rule 12b-1 of the
Act (the "Plan"),  under which the  Fund pays  the Distributor a  fee, which  is
accrued  daily and payable monthly, at an annual rate of 0.75% of the lesser of:
(a) the  average daily  aggregate gross  sales of  the Fund's  shares since  the
inception of the Fund (not including reinvestments of dividends or capital gains
distributions),  less the average daily aggregate  net asset value of the Fund's
shares redeemed  since the  Fund's inception  upon which  a contingent  deferred
sales  charge has been  imposed or waived,  or (b) the  Fund's average daily net
assets. Of the amount accrued under the Plan, 0.20% of the Fund's average  daily
net  assets is  characterized as a  service fee  within the meaning  of the NASD
guidelines. The service fee  is a payment made  for personal service and/or  the
maintenance  of shareholder accounts. The 12b-1 fee is treated by the Fund as an
expense in the year it is accrued. Amounts  paid under the Plan are paid to  the
Distributor to compensate it for
 
                                       12
<PAGE>
   
the  services provided and the  expenses borne by the  Distributor and others in
the distribution of the Fund's shares, including the payment of commissions  for
sales of the Fund's shares and incentive compensation to and expenses of DWR and
its  affiliates and other  Selected Broker-Dealers account  executives and other
employees who  engage  in or  support  distribution  of shares  or  who  service
shareholder  accounts, including  overhead and telephone  expenses; printing and
distribution of prospectuses and reports used in connection with the offering of
the Fund's shares to other than current shareholders; and preparation,  printing
and  distribution of sales literature and  advertising materials. For the fiscal
year ended December 31, 1996, the Fund accrued payments under the Plan amounting
to $1,518,807, which amount is  equal to 0.75% of  the Fund's average daily  net
assets  for the fiscal year. The payments accrued under the Plan were calculated
pursuant to clause (b) of the compensation formula under the Plan.
    
 
   
    At any given time, the expenses of distributing shares of the Fund may be in
excess of the total of  (i) the payments made by  the Fund pursuant to the  Plan
and  (ii) the  proceeds of contingent  deferred sales charges  paid by investors
upon  redemption  of  shares  (see  "Redemptions  and  Repurchases--  Contingent
Deferred  Sales Charge"). For example, if $1 million in expenses in distributing
shares of the Fund had been incurred and $750,000 had been received as described
in (i)  and  (ii)  above, the  excess  expense  would amount  to  $250,000.  The
Distributor has advised the Fund that such excess amount, including the carrying
charge  described above,  totalled $2,741,726  at December  31, 1996,  which was
equal to 1.43% of the Fund's net assets on such date.
    
 
    Because there  is no  requirement under  the Plan  that the  Distributor  be
reimbursed  for all its expenses  or any requirement that  the Plan be continued
from year to year,  this excess amount  does not constitute  a liability of  the
Fund.  Although  there is  no  legal obligation  for  the Fund  to  pay expenses
incurred in excess of payments made under  the Plan, if for any reason the  Plan
is  terminated the Trustees  will consider at  that time the  manner in which to
treat such expenses.  Any cumulative  expenses incurred, but  not yet  recovered
through  distribution fees or contingent deferred  sales charges, may or may not
be recovered  through  future distribution  fees  or contingent  deferred  sales
charges.
 
DETERMINATION OF NET ASSET VALUE
 
    The  net asset value per share of the  Fund is determined once daily at 4:00
p.m. New York time on each day that the New York Stock Exchange is open (or,  on
days  when the New York  Stock Exchange closes prior to  4 p.m., at such earlier
time), by  taking  the  value  of  all  assets  of  the  Fund,  subtracting  its
liabilities,  dividing by the number of  shares outstanding and adjusting to the
nearest
cent. 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.
 
    Certain  of the Fund's portfolio securities may be valued for the Fund by an
outside independent pricing service approved by the Fund's Trustees. The service
utilizes a computerized grid matrix of tax-exempt securities and evaluations  by
its  staff  in determining  what it  believes is  the fair  value of  the Fund's
portfolio securities.  The  Board  believes  that  timely  and  reliable  market
quotations  are  generally not  readily available  to the  Fund for  purposes of
valuing tax-exempt securities and  that the valuations  supplied by the  pricing
service are more likely to approximate the fair value of such securities.
 
    Short-term  taxable debt securities with  remaining maturities of sixty days
or less to maturity at time of purchase are valued at amortized cost, unless the
Board determines such does  not reflect the securities'  market value, in  which
case these securities will be valued at their fair market value as determined by
the  Board of  Trustees. The value  of other  assets will be  determined in good
faith under procedures established by and under the supervision of the Trustees.

SHAREHOLDER SERVICES
- --------------------------------------------------------------------------------
 
   
    AUTOMATIC INVESTMENT OF DIVIDENDS AND  DISTRIBUTIONS.  All income  dividends
and  capital gains distributions  are automatically paid  in full and fractional
shares of the  Fund, (or, if  specified by the  shareholder, any other  open-end
investment   company  for  which  InterCapital   serves  as  investment  manager
(collectively, with the Fund, the "Dean Witter Funds")), unless the  shareholder
requests  they  be paid  in  cash. Shares  so acquired  are  not subject  to the
imposition of  a contingent  deferred sales  charge upon  their redemption  (see
"Redemptions  and Repurchases"). Such dividends  and distributions will be paid,
at the net  asset value per  share, in  shares of the  Fund (or in  cash if  the
shareholder  so requests) on  the monthly payment  date, which will  be no later
than the last business day of the  month for which the dividend or  distribution
is  payable.  Processing of  dividend  checks begins  immediately  following the
monthly payment date. Shareholders  who have requested  to receive dividends  in
cash  will normally  receive their monthly  dividend check during  the first ten
days of the following month.
    
 
    EASYINVEST-SM-.   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   (see   "Purchase   of    Fund   Shares"   and   "Redemptions   and
Repurchase--Involuntary Redemption").
 
    INVESTMENT OF DIVIDENDS AND DISTRIBUTIONS RECEIVED IN CASH.  Any shareholder
who  receives  a  cash  payment   representing  a  dividend  or  capital   gains
distribution may invest such dividend or distribution at the net asset value per
share  next determined  after receipt  by the  Transfer Agent,  by returning the
check or the proceeds to the Transfer Agent within thirty days after the payment
date. Shares  so acquired  are not  subject to  the imposition  of a  contingent
deferred sales charge upon their redemption (see "Redemptions and Repurchases.")
 
   
    SYSTEMATIC  WITHDRAWAL PLAN.  A  systematic withdrawal plan (the "Withdrawal
Plan") is available  for shareholders  who own or  purchase shares  of the  Fund
having  a minimum value of $10,000 based  upon the then current net asset value.
The Withdrawal Plan provides  for monthly or  quarterly (March, June,  September
and  December) checks in  any dollar amount, not  less than $25  or in any whole
percentage of  the  account balances  on  an annualized  basis.  Any  applicable
contingent  deferred sales charge  will be imposed on  shares redeemed under the
Withdrawal Plan  (see "Redemptions  and Repurchases--Contingent  Deferred  Sales
Charge").  Therefore, any shareholder participating  in the Withdrawal Plan will
have sufficient shares  redeemed from his  or her account  so that the  proceeds
(net of any applicable contingent deferred sales charge) to the shareholder will
be the designated monthly or quarterly amount.
    
 
    Shareholders  should  contact their  DWR  or Selected  Broker-Dealer Account
Executive or the Transfer Agent for  further information about any of the  above
services.
 
EXCHANGE PRIVILEGE
 
    The  Fund  makes  available  to  its  shareholders  an  "Exchange Privilege"
allowing the exchange  of shares of  the Fund  for shares of  other Dean  Witter
Funds  sold  with a  contingent deferred  sales charge  ("CDSC funds"),  and for
shares of Dean Witter Short-Term U.S.  Treasury Trust, Dean Witter Limited  Term
Municipal  Trust, Dean Witter Short-Term Bond  Fund, Dean Witter Balanced Growth
Fund, Dean  Witter Balanced  Income  Fund, Dean  Witter Intermediate  Term  U.S.
Treasury  Trust and for five Dean Witter Funds which are money market funds (the
foregoing eleven non-CDSC or FESC funds are hereinafter collectively referred to
in this section as the "Exchange Funds"). Exchanges may be made after the shares
of the Fund acquired by purchase (not by exchange or dividend reinvestment) have
been held for thirty days.  There is no waiting  period for exchanges of  shares
acquired by exchange or dividend reinvestment.
 
                                       14
<PAGE>
    An  exchange to another CDSC  fund or any Exchange Fund  that is not a money
market fund is on the basis of the next calculated net asset value per share  of
each  fund after the  exchange order is  received. When exchanging  into a money
market fund from the Fund,  shares of the Fund are  redeemed out of the Fund  at
their  next calculated net  asset value and  the proceeds of  the redemption are
used to  purchase shares  of the  money market  fund at  their net  asset  value
determined  the following business day. Subsequent  exchanges between any of the
money market funds and any of the CDSC funds can be effected on the same  basis.
No  contingent deferred  sales charge  ("CDSC") is  imposed at  the time  of any
exchange, although any applicable CDSC will be imposed upon ultimate redemption.
Shares of the Fund acquired in exchange for shares of another CDSC fund having a
different CDSC schedule  than that  of this  Fund will  be subject  to the  CDSC
schedule  of this  Fund, even if  such shares are  subsequently re-exchanged for
shares of the  CDSC fund  originally purchased. During  the period  of time  the
shareholder  remains in the Exchange Funds (calculated  from the last day of the
month in which the shares were acquired), the holding period (for the purpose of
determining the rate of  the CDSC) is frozen.  If those shares are  subsequently
reexchanged for shares of a CDSC fund, the holding period previously frozen when
the first exchange was made resumes on the last day of the month in which shares
of  the  CDSC  fund  are reacquired.  Thus,  the  CDSC is  based  upon  the time
(calculated as described above) the shareholder was invested in a CDSC fund (see
"Redemptions and Repurchases--Contingent  Deferred Sales  Charge"). However,  in
the  case of shares  of the Fund exchanged  into the Exchange  Funds 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 Funds 12b-1 distribution fees incurred on or  after
that  date  which  are  attributable to  those  shares.  (Exchange  Funds' 12b-1
distribution fees are described in the prospectus for those funds).
 
    In addition, shares of the  Fund may be acquired  in exchange for shares  of
Dean  Witter Funds sold with a front-end sales charge ("FESC funds"), but shares
of the Fund, however acquired,  may not be exchanged  for shares of FESC  funds.
Shares  of a CDSC  fund acquired in  exchange for shares  of a FESC  Fund (or in
exchange for shares of other Dean Witter  Funds for which shares of a FESC  fund
have been exchanged) are not subject to any CDSC upon their redemption.
 
    Purchases  and  exchanges should  be made  for  investment purposes  only. A
pattern of frequent  exchanges may  be deemed by  the Investment  Manager to  be
abusive and contrary to the best interests of the Fund's other shareholders and,
at  the Investment Manager's discretion, may be limited by the Fund's refusal to
accept additional purchases and/  or exchanges from  the investor. Although  the
Fund  does not  have any  specific definition of  what constitutes  a pattern of
frequent exchanges,  and  will  consider all  relevant  factors  in  determining
whether  a particular situation is abusive and contrary to the best interests of
the Fund and its other shareholders, investors should be aware that the Fund and
each of the other Dean Witter Funds  may in their discretion limit or  otherwise
restrict  the number of  times this Exchange  Privilege may be  exercised by any
investor. Any such restriction will be made  by the Fund on a prospective  basis
only,  upon notice  to the  shareholder not later  than ten  days following such
shareholder's most recent exchange.
 
    Also, the Exchange Privilege may be terminated or revised at any time by the
Fund and/or any of such  Dean Witter Funds for which  shares of the Fund may  be
exchanged,  upon  such  notice  as  may  be  required  by  applicable regulatory
agencies. Shareholders maintaining margin accounts with DWR or another  Selected
Broker-Dealer  are referred to their account executive regarding restrictions on
exchange of shares of the Fund pledged in their margin account.
 
    The current prospectus for each  fund describes its investment  objective(s)
and  policies, and shareholders  should obtain one and  read it carefully before
investing. Exchanges are subject to the
mini-
 
                                       15
<PAGE>
mum 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 clients of DWR or another Selected
Broker-Dealer but who wish to make exchanges directly by writing or  telephoning
the  Transfer Agent) must complete and forward to the Transfer Agent an Exchange
Privilege Authorization Form, copies of which may be obtained from the  Transfer
Agent, to initiate an exchange. If the Authorization Form is used, exchanges may
be  made in writing or by contacting the Transfer Agent at (800) 869-NEWS (toll-
free). The  Fund will  employ  reasonable procedures  to confirm  that  exchange
instructions  communicated over the  telephone are genuine.  Such procedures may
include requiring various forms of personal identification such as name, mailing
address, social security  or other tax  identification number and  DWR or  other
Selected  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  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 case
with the Dean Witter Funds in the past.
 
    Additional information concerning the Exchange Privilege is available from a
DWR or other Selected Dealer account executive or the Transfer Agent.
 
REDEMPTIONS AND REPURCHASES

    REDEMPTION.  Shares of the Fund can be redeemed for cash at any time at  the
net asset value per share next determined; however, such redemption proceeds may
be  reduced by  the amount of  any applicable contingent  deferred sales charges
(see below).  If shares  are held  in a  shareholder's account  without a  share
certificate,  a written request  for redemption to the  Fund's Transfer Agent at
P.O. Box 983, Jersey City, NJ 07303 is required. If certificates are held by the
shareholder(s), the shares  may be redeemed  by surrendering the  certificate(s)
with  a written  request of  redemption, along  with any  additional information
required by the Transfer Agent.
 
   
    CONTINGENT DEFERRED SALES CHARGE.  Shares of the Fund which are held for six
years or more after purchase (calculated from the last day of the month in which
the shares were purchased)  will not be subject  to any charge upon  redemption.
Shares  redeemed sooner than six years  after purchase will, however, be subject
to a charge upon redemption. This charge is called a "contingent deferred  sales
charge"  ("CDSC"), which  will be  a percentage of  the dollar  amount of shares
redeemed and will be
    
 
                                       16
<PAGE>
assessed on an amount  equal to the  lesser of the current  market value or  the
cost  of the shares being redeemed. The size of this percentage will depend upon
how long the shares have been held, and is set forth in the table below:

Sixth..............................              1.0%
Seventh and thereafter.............            None
</TABLE>
 
    A CDSC will not be imposed on:  (i) any amount which represents an  increase
in value of shares purchased within the six years preceding the redemption; (ii)
the current net asset value of shares purchased more than six years prior to the
redemption;  and (iii) the  current net asset value  of shares purchased through
reinvestment of dividends  or distributions and/or  shares acquired in  exchange
for  shares of Dean Witter Funds sold with  a front-end sales charge or of other
Dean Witter Funds acquired in exchange for such shares. Moreover, in determining
whether a CDSC is applicable it will  be assumed that amounts described in  (i),
(ii), and (iii) above (in that order) are redeemed first.
 
    In  addition, the CDSC, if otherwise applicable,  will be waived in the case
of:
 
    (1) redemptions of  shares held at  the time a  shareholder dies or  becomes
disabled,  only if  the shares  are:  (A)  registered either  in the  name of an
individual shareholder (not a  trust), or in the  names of such shareholder  and
his  or her spouse as joint tenants with right of survivorship; or   (B) held in
a qualified corporate  or self-employed retirement  plan, Individual  Retirement
Account  ("IRA") or  Custodial Account under  Section 403(b)(7)  of the Internal
Revenue Code  ("403(b) Custodial  Account"), provided  in either  case that  the
redemption is requested within one year of the death or initial determination of
disability;
 
    (2)   redemptions  in   connection  with   the  following   retirement  plan
distributions:  (A) lump-sum or  other distributions from a qualified  corporate
or self-employed retirement plan following retirement (or, in the case of a "key
employee"  of  a  "top  heavy"  plan,  following  attainment  of  age  59  1/2);
(B) distributions from an IRA  or 403(b) Custodial Account following  attainment
of  age 59 1/2; or   (C) a  tax-free return of an excess contribution to an IRA;
and
 
   
    (3) all redemptions of  shares held for  the benefit of  a participant in  a
corporate or self-employed retirement plan qualified under Section 401(k) of the
Internal   Revenue  Code  which  offers  investment  companies  managed  by  the
Investment Manager  or its  subsidiary, Dean  Witter Services  Company Inc.,  as
self-directed investment alternatives and for which Dean Witter Trust Company or
Dean  Witter Trust FSB, each of which is an affiliate of the Investment Manager,
serves as Trustee ("Eligible 401(k) Plan"), provided that either:  (A) the  plan
continues  to be  an Eligible  401(k) Plan after  the redemption;  or    (B) the
redemption is in connection with the complete termination of the plan  involving
the distribution of all plan assets to participants.
    
 
    With  reference to (1) above, for the purpose of determining disability, the
Distributor utilizes the definition of disability contained in Section  72(m)(7)
of  the  Internal Revenue  Code, which  relates  to the  inability to  engage in
gainful employment. With reference  to (2) above,  the term "distribution"  does
not  encompass a direct transfer of  IRA, 403(b) Custodial Account or retirement
plan assets to  a successor custodian  or trustee. All  waivers will be  granted
only  following receipt by the Distributor  of confirmation of the shareholder's
entitlement.
 
    REPURCHASE.    DWR  or  other  Selected  Broker-Dealers  are  authorized  to
repurchase  shares, represented by a share certificate which is delivered to any
of their  offices.  Shares held  in  a  shareholder's account  without  a  share
certificate may also be repurchased by DWR or other Selected Broker-Dealers upon
the telephonic request of the
share-
 
                                       17
<PAGE>
holder. The repurchase price is the net asset value next computed (see "Purchase
of  Fund  Shares") after  such  repurchase order  is  received by  DWR  or other
Selected Broker-Dealers are, reduced by any applicable CDSC.
 
    The CDSC, if any, will be the only fee imposed upon repurchase by either the
Fund, the Distributor or DWR. The offer by DWR or other Selected  Broker-Dealers
to  repurchase shares may  be suspended without  notice by them  at any time. In
that event, shareholders  may redeem  their shares through  the Fund's  Transfer
Agent as set forth above under "Redemption."
 
    PAYMENT  FOR SHARES REDEEMED  OR REPURCHASED.   Payment for shares presented
for repurchase  or redemption  will be  made by  check within  seven days  after
receipt  by the Transfer Agent of the certificate and/or written request in good
order. Such payment may be postponed or the right of redemption suspended  under
unusual  circumstances, e.g., when normal trading is not taking place on the New
York Stock Exchange. If the shares  to be redeemed have recently been  purchased
by check, payment of the redemption proceeds may be delayed for the minimum time
needed  to verify that the check used  for investment has been honored (not more
than fifteen days from the time of receipt of the check by the Transfer  Agent).
Shareholders   maintaining   margin  accounts   with   DWR  or   other  Selected
Broker-Dealers are referred to their account executive regarding restrictions on
redemption of shares of the Fund pledged in the margin account.
 
    REINSTATEMENT PRIVILEGE.   A  shareholder  who has  had  his or  her  shares
redeemed  or  repurchased and  has not  previously exercised  this reinstatement
privilege  may,  within  thirty  days  after  the  date  of  the  redemption  or
repurchase,  reinstate any portion or all of  the proceeds of such redemption or
repurchase in shares of the Fund at the net asset value next determined after  a
reinstatement  request, together with the proceeds,  is received by the Transfer
Agent and receive a pro-rata  credit for any CDSC  paid in connection with  such
redemption or repurchase.
 
   
    INVOLUNTARY  REDEMPTION.   The Fund reserves  the right to  redeem, on sixty
days' notice and 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  have a value  of
less  than $100 as a result of redemptions or repurchases, or such lesser amount
as may be fixed by the  Board of Trustees or, in  the case of an account  opened
through  EasyInvest, if  after twelve months  the shareholder  has invested less
than $1,000 in  the account. However,  before the Fund  redeems such shares  and
sends  the proceeds to the shareholder, it  will notify the shareholder that the
value of the  shares is less  than the applicable  amount and allow  him or  her
sixty days to make an additional investment in an amount which will increase the
value of his or her account to at least the applicable amount or more before the
redemption is processed. No CDSC will be imposed on any involuntary redemption.
    
 
DIVIDENDS, DISTRIBUTIONS AND TAXES
- --------------------------------------------------------------------------------
 
    DIVIDENDS   AND  DISTRIBUTIONS.    The  Fund  declares  dividends  from  net
investment income on each day the New  York Stock Exchange is open for  business
(see  "Purchase of Fund  Shares"). Such dividends are  payable monthly. The Fund
intends to distribute substantially all of  the Fund's net investment income  on
an annual basis.
 
    The  Fund will distribute at least once each year all net short-term capital
gains, if there are any. The  Fund may, however, determine either to  distribute
or  to retain all  or part of  any net long-term  capital gains in  any year for
reinvestment. All  dividends and  capital gains  distributions will  be paid  in
additional  Fund shares (without sales charge) and automatically credited to the
shareholder's account  without  issuance  of  a  share  certificate  unless  the
shareholder
 
                                       18
<PAGE>
requests   in   writing  that   they  be   paid   in  cash.   (See  "Shareholder
Services--Automatic Investment of Dividends and Distributions".) Taxable capital
gains may be generated by transactions in options and futures contracts  engaged
in  by the Fund. Any dividends or  distributions declared in the last quarter of
any calendar  year  which are  paid  in the  following  calendar year  prior  to
February  1, will  be deemed  received by  shareholders of  record in  the prior
calendar year.
 
    TAXES.  Because the Fund  currently intends to distribute substantially  all
of  its net investment income  and capital gains to  shareholders and intends to
otherwise comply with all the provisions of Subchapter M of the Internal Revenue
Code (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 continue 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, distributions  from  net
investment  income  to  shareholders, whether  taken  in cash  or  reinvested in
additional shares, will be excludable from  gross income for federal income  tax
purposes  to  the extent  net investment  income is  represented by  interest on
tax-exempt securities.
 
    Individual shareholders  who  are New  York  residents will  not  incur  any
federal,  New  York  State  or  New  York  City  income  tax  on  the  amount of
exempt-interest dividends  received by  them from  the Fund  which represents  a
distribution of income from New York tax-exempt securities whether taken in cash
or  reinvested  in additional  shares.  Exempt-interest dividends  are included,
however, in determining  what portion,  if any,  of a  person's Social  Security
benefits  are subject to federal income tax.  Within sixty days after the end of
its taxable year, the Fund will mail to shareholders 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.
 
    The  Code  may subject  interest  received on  certain  otherwise tax-exempt
securities to an alternative  minimum tax. This alternative  minimum tax may  be
incurred due 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. A
portion of the Fund's investments may be made in such "private activity  bonds,"
with the result that a portion of the exempt-interest dividends paid by the Fund
will  be an item  of tax preference  to shareholders subject  to the alternative
minimum tax.  In  addition,  certain  corporations  which  are  subject  to  the
alternative  minimum  tax  may  have to  include  a  portion  of exempt-interest
dividends in calculating their alternative minimum taxable income in  situations
where the "adjusted current earnings" of the corporation exceeds its alternative
minimum taxable income.
 
    Under the Revenue Reconciliation Act of 1993, all or a portion of the Fund's
gain from the sale or redemption of tax-exempt obligations purchased at a market
discount  after April 30,  1993 will be  treated as ordinary  income rather than
capital gain. This  rule may increase  the amount of  ordinary income  dividends
received by shareholders.
 
    Shareholders will normally be subject to federal, New York State or New York
City  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.
Distributions    from   investment   income   and   capital   gains,   including
exempt-interest dividends,  may  be  subject  to New  York  franchise  taxes  if
received by a corporation
 
                                       19
<PAGE>
doing  business in New York, to state taxes in states other than New York and to
local taxes. 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.
 
   
    The Fund may at times  make payments from sources  other than income or  net
capital gains. Payments from such sources will, in effect, represent a return of
a  portion of each shareholder's investment. All, or a portion, of such payments
will not be taxable to shareholders.
    
 
    Any loss on the sale  or exchange of shares of  the Fund which are held  for
six  months  or  less  is  disallowed  to  the  extent  of  the  amount  of  any
exempt-interest dividend paid with respect to such shares. Treasury  Regulations
may  provide for a reduction in such  required holding periods. If a shareholder
receives a distribution that is taxed as a long-term capital gain on shares held
for six moths or less and sells those shares at a loss, the loss will be treated
as a long-term capital loss.
 
    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 state or 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.
    
 
PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------
 
    From time to time the Fund may  quote its "yield" and/or its "total  return"
in  advertisements and sales literature. Both the  yield and the total return of
the Fund  are based  on historical  earnings and  are not  intended to  indicate
future  performance. The  yield of  the Fund  will be  computed by  dividing the
Fund's net investment income over a 30-day period by an average value (using the
average number of shares entitled to  receive dividends and the net asset  value
per  share  at  the  end  of the  period),  all  in  accordance  with applicable
regulatory requirements.  Such amount  is  compounded for  six months  and  then
annualized  for a twelve-month period  to derive the Fund's  yield. The Fund may
also quote  its tax-equivalent  yield, which  is calculated  by determining  the
pre-tax  yield which, after being taxed at a stated rate, would be equivalent to
the yield determined as described above.
 
   
    The "average annual total return" of the Fund refers to a figure  reflecting
the  average annualized  percentage increase  (or decrease)  in the  value of an
initial investment in the Fund of $1,000  over a period of one, five, ten  years
or  over the life of  the Fund. Average annual  total return reflects all income
earned by the Fund, any appreciation  or depreciation of the Fund's assets,  all
expenses  incurred by the Fund and all  sales charges which would be incurred by
redeeming shareholders, for the stated periods. It also assumes reinvestment  of
all dividends and distributions paid by the Fund.
    
 
    In  addition to the foregoing, the Fund  may advertise its total return over
different periods of time by means of aggregate, average, year-by-year or  other
types  of total  return figures.  Such calculations may  or may  not reflect the
deduction of the  contingent deferred  sales charge which,  if reflected,  would
reduce  the  performance  quoted. The  Fund  may  also advertise  the  growth of
hypothetical investments of $10,000, $50,000 and $100,000 in shares of the Fund.
The Fund  from time  to time  may  also advertise  its performance  relative  to
certain  performance rankings and indexes  compiled by independent organizations
(such as mutual fund performance rankings of Lipper Analytical Services, Inc.).

ADDITIONAL INFORMATION
- --------------------------------------------------------------------------------
 
    VOTING RIGHTS.  All shares of beneficial  interest of the Fund are of  $0.01
par value and are equal as to earnings, assets and voting privileges.
 
    The  Fund is not required to hold Annual Meetings of Shareholders and, under
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 the obligations of  the
Fund.  However,  the  Declaration of  Trust  contains an  express  disclaimer of
shareholder liability for acts  or obligations of the  Fund, requires that  Fund
obligations  include  such  disclaimer  and  provides  for  indemnification  and
reimbursement of expenses out  of the Fund's property  for any shareholder  held
personally  liable  for  the  obligations  of the  Fund.  Thus,  the  risk  of a
shareholder incurring  financial loss  on account  of shareholder  liability  is
limited  to circumstances in which  the Fund itself would  be unable to meet its
obligations. Given the above limitations  on shareholder personal liability  and
the  nature of the Fund's  assets and operations, the  possibility of the Fund's
being unable  to  meet  its  obligations  is  remote  and,  in  the  opinion  of
Massachusetts  counsel to  the Fund, the  risk to Fund  shareholders of personal
liability is remote.
 
    CODE OF ETHICS.   Directors,  officers and employees  of InterCapital,  Dean
Witter Services Company Inc. and the Distributor are subject to a strict Code of
Ethics adopted by those companies. The Code of Ethics is intended to ensure that
the interests of shareholders and other clients are placed ahead of any personal
interest,  that no undue personal benefit is obtained from a person's employment
activities and that actual and potential  conflicts of interest are avoided.  To
achieve  these goals and comply with regulatory requirements, the Code of Ethics
requires, among other things, that personal securities transactions by employees
of the companies be subject to an  advance clearance process to monitor that  no
Dean  Witter Fund is engaged at the same time  in a purchase or sale of the same
security. The  Code of  Ethics bans  the purchase  of securities  in an  initial
public  offering and prohibits engaging in  futures and options transactions and
profiting on short-term trading (that is, a purchase within sixty days of a sale
or a  sale  within  sixty days  of  a  purchase) of  a  security.  In  addition,
investment  personnel may  not purchase  or sell  a security  for their personal
account within thirty days  before or after any  transaction in any Dean  Witter
Fund  managed  by them.  Any violations  of the  Code of  Ethics are  subject to
sanctions,  including  reprimand,  demotion  or  suspension  or  termination  of
employment.  The Code  of Ethics comports  with regulatory  requirements and the
recommendations in the 1994 report by the Investment Company Institute  Advisory
Group on Personal Investing.

- --------------------------------------------------------------------------------
 
    Dean  Witter  New York  Tax-Free Income  Fund (the  "Fund") is  an open-end,
diversified management  investment  company  whose investment  objective  is  to
provide  a high level of current income  exempt from federal, New York State and
New York City  income tax,  consistent with  preservation of  capital. The  Fund

THE FUND AND ITS MANAGEMENT
- --------------------------------------------------------------------------------
 
THE FUND
 
    The  Fund is a Fund of the  type commonly known as a "Massachusetts business
trust" and was organized under the laws of the Commonwealth of Massachusetts  on
January 17, 1985.
 
THE INVESTMENT MANAGER
 
   
    Dean  Witter  InterCapital  Inc., a  Delaware  corporation  (the "Investment
Manager" or "InterCapital"), whose address is Two World Trade Center, New  York,
New York 10048, is the Fund's Investment Manager. InterCapital is a wholly-owned
subsidiary  of 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 performed by the InterCapital  Division of Dean Witter Reynolds  Inc.
("DWR"), a broker-dealer affiliate of InterCapital. (As hereinafter used in this
Statement  of Additional  Information, the terms  "InterCapital" and "Investment
Manager"  refer  to   DWR's  InterCapital   Division  prior   to  the   internal
reorganization   and  Dean  Witter  InterCapital  Inc.  thereafter.)  The  daily
management of  the  Fund  and  research relating  to  the  Fund's  portfolio  is
conducted  by  or  under  the direction  of  officers  of the  Fund  and  of the
Investment Manager, subject to periodic review by the Fund's Board of  Trustees.
Information  as to  these trustees and  officers is contained  under the caption
"Trustees and Officers."

ment companies, together with the Fund, are collectively referred to as the Dean
Witter  Funds.  In  addition,  Dean Witter  Services  Company  Inc.  ("DWSC"), a
wholly-owned subsidiary of  InterCapital, serves  as manager  for the  following
companies  for which TCW Funds Management Inc. is the investment adviser: TCW/DW
Core Equity Trust, TCW/DW North American Government Income Trust, TCW/ DW  Latin
American  Growth Fund,  TCW/DW Income and  Growth Fund, TCW/DW  Small Cap Growth
Fund, TCW/DW Balanced  Fund, TCW/DW  Total Return Trust,  TCW/DW Mid-Cap  Equity
Trust,  TCW/DW  Global  Telecom  Trust, TCW/DW  Strategic  Income  Trust, TCW/DW
Emerging Markets Opportunities Trust, TCW/DW Term Trust 2000, TCW/DW Term  Trust
2002  and TCW/DW Term Trust 2003 (the "TCW/ DW Funds"). InterCapital also serves
as: (i)  sub-adviser  to  Templeton  Global  Opportunities  Trust,  an  open-end
investment  company; (ii)  administrator of  The BlackRock  Strategic Term Trust
Inc., a closed-end investment company; and (iii) sub-administrator of MassMutual
Participation  Investors  and   Templeton  Global   Governments  Income   Trust,
closed-end investment companies.
    
 
    Pursuant  to an Investment  Management Agreement (the  "Agreement") with the
Investment Manager, the Fund has retained  the Investment Manager to manage  the
investment  of  the  Fund's assets,  including  the  placing of  orders  for the
purchase and sale of  portfolio securities. The  Investment Manager obtains  and
evaluates  such  information  and  advice relating  to  the  economy, securities
markets, and  specific  securities  as  it  considers  necessary  or  useful  to
continuously  manage the  assets of  the Fund  in a  manner consistent  with its
investment objective and policies.
 
    Under the  terms  of the  Agreement,  in  addition to  managing  the  Fund's
investments,  the Investment Manager  maintains certain of  the Fund's books and
records and  furnishes,  at its  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, 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. On  April 17,
1995, DWSC was  reorganized in the  State of Delaware,  necessitating the  entry
into  a  new Services  Agreement  by InterCapital  and  DWSC on  that  date. The
foregoing internal reorganizations did not result in any change in the nature or
scope of the administrative services  being provided to the  Fund or any of  the
fees  being paid by the Fund for  the overall services being performed under the
terms of the existing Agreement.
 
    Expenses not expressly assumed by the Investment Manager under the Agreement
or by  the Distributor  of  the Fund's  shares,  Dean Witter  Distributors  Inc.
("Distributors"  or the "Distributor")  (see "The Distributor")  will be paid by
the Fund. The expenses borne by the  Fund include, but are not limited to:  fees
pursuant  to any  plan of distribution,  charges and expenses  of any registrar,
custodian, stock transfer and dividend disbursing agent; brokerage  commissions;
taxes; engraving and printing stock 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;
inter-
 
                                       4

est on Fund  borrowings; postage;  insurance premiums on  property or  personnel
(including  officers  and trustees)  of  the Fund  which  inure to  its benefit;
extraordinary  expenses  (including,  but  not  limited  to,  legal  claims  and
liabilities  and litigation costs and any indemnification relating thereto); and
all other costs of the Fund's operation.
 
   
    As full compensation for the services  and facilities furnished to the  Fund
and  expenses of the Fund  assumed by the Investment  Manager, the Fund pays the
Investment Manager monthly compensation calculated daily by applying the  annual
rate of 0.55% to the Fund's net assets not exceeding $500 million and the annual
rate  of 0.525% to the Fund's net  assets exceeding $500 million. For the fiscal
years ended December 31, 1994, 1995 and 1996, the Fund accrued to the Investment
Manager total compensation under  the Agreements in  the amounts of  $1,254,000,
$1,179,074  and $1,113,792, respectively. The Investment Manager has voluntarily
undertaken that, if  in any  fiscal year  the Fund's  total operating  expenses,
exclusive   of   taxes,  interest,   distribution   fees,  brokerage   fees  and
extraordinary expenses,  exceed  1  1/2%,  of  average  daily  net  assets,  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.  This
undertaking can be revoked by the Investment Manager at any time. For the fiscal
year  ended  December  31,  1996,  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  does not  restrict  the Investment  Manager from
acting as investment manager or adviser to others.
 
   
    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  the prior  investment  management agreement  which  was initially
approved by the Board of  Trustees on February 13, 1985  and by DWR as the  then
sole  shareholder of the  Fund on March  20, 1985. 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).  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 such is defined in the Act.
    
 
   
    Under its terms, the Agreement had an initial term ending April 30, 1994 and
provides  that  it  will  continue  from  year  to  year  thereafter,   provided
continuance  of the Agreement is  approved at least annually  by the vote of the
holders of a majority, as defined in  the Act, of the outstanding shares of  the
Fund,  or by the  Board of Trustees of  the Fund; provided  that in either event
such continuance is approved annually by the vote of a majority of the  Trustees
of  the Fund who  are not parties  to the Agreement  or "interested persons" (as
defined in the Act) of any  such party, which vote must  be cast in person at  a
meeting called for the purpose of voting on such approval. At their meeting held
on  April  17,  1996,  the  Fund's  Board  of  Trustees,  including  all  of the
Independent Trustees,  approved continuance  of the  Agreement until  April  30,
1997.
    
 
   
    The Fund has acknowledged that the name "Dean Witter" is a property right of
DWR. The Fund has agreed that DWR or its parent company may use or, at any time,
permit  others to use, the name "Dean Witter."  The Fund has also agreed that in
the  event  the  Agreement  is   terminated,  or  if  the  affiliation   between
InterCapital  and its  parent is  terminated, the  Fund will  eliminate the name
"Dean Witter" from its name if DWR or its parent company shall so request.

THE BOARD OF TRUSTEES, THE INDEPENDENT TRUSTEES, AND THE COMMITTEES
    
 
   
    The Board of Trustees consists of eight (8) trustees. These same individuals
also  serve as directors or  trustees for all of the  Dean Witter Funds, and are
referred to in this  section as Trustees.  As of the date  of this Statement  of
Additional  Information, there are a total of 84 Dean Witter Funds, comprised of
126 portfolios. As of  February 28, 1997,  the Dean Witter  Funds had total  net
assets of approximately $89.8 billion and more than six million shareholders.
    
 
   
    Six  Trustees  (75% of  the total  number) have  no affiliation  or business
connection with InterCapital or any of its affiliated persons and do not own any
stock or other securities issued  by InterCapital's parent company, DWDC.  These
are  the "disinterested" or "independent" Trustees.  The other two Trustees (the
"management Trustees")  are  affiliated  with  InterCapital.  Four  of  the  six
independent Trustees are also Independent Trustees of the TCW/DW Funds.
    
 
   
    Law and regulation establish both general guidelines and specific duties for
the  Independent Trustees.  The Dean Witter  Funds seek  as Independent Trustees
individuals of distinction  and experience in  business and finance,  government
service  or academia; these are people whose advice and counsel are in demand by
others and for  whom there is  often competition.  To accept a  position on  the
Funds'  Boards, such individuals may reject other attractive assignments because
the Funds make  substantial demands  on their time.  Indeed, by  serving on  the
Funds'  Boards, certain Trustees who would  otherwise be qualified and in demand
to serve on bank boards would be prohibited by law from doing so.
    
 
   
    All of the Independent Trustees serve as members of the Audit Committee  and
the  Committee of the Independent Trustees. Three  of them also serve as members
of the Derivatives Committee. During the calendar year ended December 31,  1996,
the  three Committees held a combined  total of sixteen meetings. The Committees
hold some  meetings at  InterCapital's offices  and some  outside  InterCapital.
Management  Trustees or  officers do not  attend these meetings  unless they are
invited for purposes of furnishing information or making a report.
    
 
   
    The Committee of the  Independent Trustees is  charged with recommending  to
the  full Board approval  of management, advisory  and administration contracts,
Rule 12b-1  plans  and  distribution and  underwriting  agreements;  continually
reviewing  Fund performance;  checking on  the pricing  of portfolio securities,
brokerage commissions, transfer agent costs  and performance, and trading  among
Funds  in the  same complex; and  approving fidelity bond  and related insurance
coverage and allocations, as well as other matters that arise from time to time.
The Independent Trustees are required to select and nominate individuals to fill
any Independent Trustee vacancy on the Board  of any Fund that has a Rule  12b-1
plan of distribution. Most of the Dean Witter Funds have such a plan.
    
 
                                       8
<PAGE>
   
    The  Audit  Committee is  charged with  recommending to  the full  Board the
engagement  or  discharge  of  the  Fund's  independent  accountants;  directing
investigations  into matters  within the  scope of  the independent accountants'
duties, including the power  to retain outside  specialists; reviewing with  the
independent  accountants the audit plan and  results of the auditing engagement;
approving professional  services provided  by  the independent  accountants  and
other  accounting firms prior to the performance of such services; reviewing the
independence of the independent accountants; considering the range of audit  and
non-audit  fees;  reviewing  the  adequacy  of  the  Fund's  system  of internal
controls; and preparing  and submitting  Committee meeting minutes  to the  full
Board.
    
 
   
    Finally,  the  Board of  each  Fund has  formed  a Derivatives  Committee to
establish parameters for and oversee the activities of the Fund with respect  to
derivative investments, if any, made by the Fund.
    
 
   
DUTIES OF CHAIRMAN OF COMMITTEE OF THE INDEPENDENT TRUSTEES AND AUDIT COMMITTEE
    
 
   
    The  Chairman of  the Committee  of the  Independent Trustees  and the Audit
Committee maintains an  office at  the Funds' headquarters  in New  York. He  is
responsible  for keeping abreast of regulatory and industry developments and the
Funds' operations and management. He  screens and/or prepares written  materials
and  identifies  critical  issues  for  the  Independent  Trustees  to consider,
develops agendas  for Committee  meetings,  determines the  type and  amount  of
information  that the Committees will need to form a judgment on various issues,
and arranges to have  that information furnished to  Committee members. He  also
arranges  for  the services  of independent  experts and  consults with  them in
advance of meetings  to help  refine reports and  to focus  on critical  issues.
Members of the Committees believe that the person who serves as Chairman of both
Committees  and guides their efforts is  pivotal to the effective functioning of
the Committees.
    
 
   
    The Chairman of the  Committees also maintains  continuous contact with  the
Funds' management, with independent counsel to the Independent Trustees and with
the  Funds' independent auditors.  He arranges for a  series of special meetings
involving the  annual  review  of  investment  advisory,  management  and  other
operating  contracts of  the Funds  and, on  behalf of  the Committees, conducts
negotiations with the Investment Manager and other service providers. In effect,
the Chairman of the  Committees serves as a  combination of chief executive  and
support staff of the Independent Trustees.
    
 
   
    The  Chairman of  the Committee  of the  Independent Trustees  and the Audit
Committee is  not  employed by  any  other  organization and  devotes  his  time
primarily  to the  services he  performs as  Committee Chairman  and Independent
Trustee of the Dean Witter Funds and  as an Independent Trustee and, since  July
1,  1996, as Chairman of the Committee of the Independent Trustees and the Audit
Committee of the TCW/DW Funds. The current Committee Chairman has had more  than
35 years experience as a senior executive in the investment company industry.
    
 
   
ADVANTAGES OF HAVING SAME INDIVIDUALS AS INDEPENDENT TRUSTEES FOR ALL DEAN
WITTER FUNDS
    
 
   
    The  Independent Trustees and the Funds'  management believe that having the
same Independent  Trustees  for  each  of  the  Dean  Witter  Funds  avoids  the
duplication  of  effort  that  would  arise  from  having  different  groups  of
individuals serving as  Independent Trustees for  each of the  Funds or even  of
sub-groups  of Funds.  They believe  that having  the same  individuals serve as
Independent Trustees of  all the  Funds tends  to increase  their knowledge  and
expertise regarding matters which affect the Fund complex generally and enhances
their  ability  to negotiate  on behalf  of  each Fund  with the  Fund's service
providers. This arrangement also precludes the possibility of separate groups of
Independent Trustees arriving at conflicting decisions regarding operations  and
management  of the  Funds and  avoids the cost  and confusion  that would likely
ensue. Finally, having the  same Independent Trustees serve  on all Fund  Boards
enhances  the ability of  each Fund to  obtain, at modest  cost to each separate
Fund, the services of Independent Trustees, and a Chairman of their  Committees,
of  the caliber, experience and business acumen  of the individuals who serve as
Independent Trustees of the Dean Witter Funds.
    
 
   
COMPENSATION OF INDEPENDENT TRUSTEES
    
 
   
    The Fund pays each Independent  Trustee an annual fee  of $1,000 plus a  per
meeting  fee of $50 for  meetings of the Board of  Trustees or committees of the
Board of Trustees attended by the Trustee (the
    
 
                                       9
<PAGE>
   
Fund pays the Chairman of the Audit Committee an annual fee of $750 and pays the
Chairman of the Committee of the  Independent Trustees an additional annual  fee
of  $1,200).  The  Fund  also  reimburses such  Trustees  for  travel  and other
out-of-pocket expenses  incurred  by  them in  connection  with  attending  such
meetings. Trustees and officers of the Fund who are or have been employed by the
Investment  Manager or an affiliated company  receive no compensation or expense
reimbursement from the Fund.

Independent Trustees by the Fund for the fiscal year ended December 31, 1996.

    As  of the date of this Statement  of Additional Information, 57 of the Dean
Witter Funds, including the Fund, have adopted a retirement program under  which
an  Independent Trustee who  retires after serving  for at least  five years (or
such lesser period as may be determined by the Board) as an Independent Director
or Trustee of any Dean Witter Fund that has adopted the retirement program (each
such Fund referred to as an "Adopting Fund" and each such Trustee referred to as
an "Eligible  Trustee") is  entitled to  retirement payments  upon reaching  the
eligible  retirement age (normally, after attaining age 72). Annual payments are
based upon length of service. Currently, upon retirement, each Eligible  Trustee
is  entitled to  receive from  the Adopting  Fund, commencing  as of  his or her
retirement date and continuing for the remainder  of his or her life, an  annual
retirement benefit (the "Regular Benefit") equal to 25.0% of his or her Eligible
Compensation  plus 0.4166666% of such Eligible  Compensation for each full month
of service as an Independent Director or Trustee of any Adopting Fund in  excess
of five years up to a maximum of 50.0% after ten years of service. The foregoing
percentages may be changed by the
    
 
                                       10

Board.(1)  "Eligible Compensation" is one-fifth of the total compensation earned
by such Eligible  Trustee for  service to  the Adopting  Fund in  the five  year
period  prior to the  date of the Eligible  Trustee's retirement. Benefits under
the retirement program are not secured or funded by the Adopting Funds.
    
 
   
    The following  table  illustrates the  retirement  benefits accrued  to  the
Fund's  Independent Trustees by the Fund for  the fiscal year ended December 31,
1996 and by the  57 Dean Witter  Funds (including the Fund)  for the year  ended
December  31,  1996,  and  the  estimated  retirement  benefits  for  the Fund's
Independent Trustees, to  commence upon their  retirement, from the  Fund as  of
December 31, 1996 and from the 57 Dean Witter Funds as of December 31, 1996.

(1)  An Eligible Trustee may  elect alternate payments of  his or her retirement
    benefits based upon the  combined life expectancy  of such Eligible  Trustee
    and his or her spouse on the date of such Eligible Trustee's retirement. The
    amount  estimated to be payable under  this method, through the remainder of
    the later of  the lives of  such Eligible  Trustee and spouse,  will be  the
    actuarial  equivalent  of the  Regular  Benefit. In  addition,  the Eligible
    Trustee may elect that the  surviving spouse's periodic payment of  benefits
    will  be equal  to either 50%  or 100%  of the previous  periodic amount, an
    election that, respectively,  increases or decreases  the previous  periodic
    amount  so that the  resulting payments will be  the actuarial equivalent of
    the Regular Benefit.

    As of the date  of this Statement of  Additional Information, the  aggregate
number of shares of beneficial interest of the Fund owned by the Fund's officers
and  Trustees  as a  group  was less  than  1 percent  of  the Fund's  shares of
beneficial interest 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, non-New York
tax-exempt securities, futures and options. Investments in taxable money  market
instruments   would  generally   be  made  under   any  one   of  the  following
circumstances: (a) pending investment of proceeds of sales 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.
 
    In addition, the  Fund may  temporarily invest more  than 20%  of its  total
assets   in  non-New  York  tax-exempt   securities  and  taxable  money  market
instruments, or  in tax-exempt  securities subject  to the  federal  alternative
minimum tax for individual shareholders, to maintain a "defensive" posture when,
in  the opinion of the  Investment Manager, it is advisable  to do so because of
market conditions. The types  of taxable 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
 
                                       11
<PAGE>
United States Government, its  agencies, instrumentalities or authorities;  (ii)
commercial paper rated P-1 by Moody's Investors Service, 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.
 
    TAX-EXEMPT SECURITIES.  As discussed in the Prospectus, at least 80% of  the
Fund's total assets will be invested in New York tax-exempt securities (New York
Municipal  Bonds, New  York Municipal  Notes and  New York  Municipal Commercial
Paper). 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 that 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.
 
    The Fund  does  not  have  any  minimum  quality  rating  standard  for  its
downgraded  investments. As such, the  Fund may hold securities  rated as low as
Caa, Ca or C by  Moody's or CCC, CC, C  or CI by S&P. Bonds  rated Caa or Ca  by
Moody's  may already be  in default on  payment of interest  or principal, while
bonds rated C by Moody's,  their lowest bond rating,  can be regarded as  having
extremely  poor prospects of ever attaining  any real investment standing. Bonds
rated CI  by  S&P, their  lowest  bond rating,  are  no longer  making  interest
payments.
 
    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 United States territory or possession, 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 issuance 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.
 
    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.  They may be issued at a discount  and
are  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  to  be paid  from general
revenues of the municipality  or refinanced with long-term  debt. In most  cases
Municipal  Commercial Paper is backed by  letters of credit, lending agreements,
note repurchase agreements or other credit facility agreements offered by  banks
or other institutions.
 
                                       12
<PAGE>
    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.
 
RISK CONSIDERATIONS
 
    Because of the special nature of securities which are rated below investment
grade  by  national  credit  rating  agencies  ("lower-rated  securities"),  the
Investment Manager  must take  into account  certain special  considerations  in
assessing  the  risks  associated with  such  investments. For  example,  as the
lower-rated securities market  is relatively  new, its growth  has paralleled  a
long economic expansion and it has not weathered a recession in its present size
and  form.  Therefore, an  economic downturn  or increase  in interest  rates is
likely to  have a  negative  effect on  this  market and  on  the value  of  the
lower-rated  securities  held by  the Fund,  as well  as on  the ability  of the
securities' issuers to repay principal and interest on their borrowings.
 
   
    The prices of lower-rated securities have been found to be less sensitive to
changes in  prevailing interest  rates than  higher-rated investments,  but  are
likely   to  be  more  sensitive  to  adverse  economic  changes  or  individual
issuer/debtor developments. During an economic downturn or substantial period of
rising interest rates, highly leveraged issuers may experience financial  stress
which  would  adversely  affect their  ability  to service  their  principal and
interest payment  obligations, to  meet  their projected  business goals  or  to
obtain  additional financing. If the issuer  of a fixed-income security owned by
the Fund defaults, the Fund may  incur additional expenses to seek recovery.  In
addition,  periods of economic uncertainty and  change can be expected to result
in an increased  volatility of  market prices of  lower rated  securities and  a
concomitant  volatility in the net asset value of a share of the Fund. Moreover,
the market  prices of  certain  of the  Fund's  portfolio securities  which  are
structured  as  zero  coupon securities  are  affected  to a  greater  extent by
interest rate changes and thereby tend to be more volatile than securities which
pay interest periodically and in cash (see "Dividends, Distributions and  Taxes"
for a discussion of the tax ramifications of investments in such securities).
    
 
    The  secondary market for lower-rated securities may be less liquid than the
markets for higher quality securities and,  as such, may have an adverse  effect
on  the market prices of certain securities. The limited liquidity of the market
may also adversely affect the ability of the Fund's Trustees to arrive at a fair
value for certain  lower-rated securities at  certain times and  should make  it
difficult for the Fund to sell certain securities.
 
    New laws and proposed new laws may have a potentially negative impact on the
market  for  lower-rated securities.  For  example, recent  legislation requires
federally-insured savings and loan associations  to divest their investments  in
lower-rated securities. This legislation and other proposed legislation may have
an  adverse effect  upon the value  of lower-rated securities  and a concomitant
negative impact upon the net asset value of a share of the Fund.
 
   
    VARIABLE RATE OBLIGATIONS.  As stated in the Prospectus, the Fund may invest
in obligations of the type called "variable 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.  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. 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
the obligation prior to maturity, is enhanced.
    
 
    LENDING OF PORTFOLIO SECURITIES.  The Fund may lend portfolio securities  to
brokers, dealers and financial institutions provided that cash equal to at least
100%,  of the market value of the securities loaned is deposited by the borrower
with  the  Fund   and  is  maintained   each  business  day   in  a   segregated
 
                                       13
<PAGE>
   
account  pursuant to applicable regulations. While  such securities are on loan,
the borrower will pay  the Fund any  income accruing thereon,  and the Fund  may
invest  the cash collateral in  portfolio securities, thereby earning additional
income. The Fund will not  lend its portfolio securities  if such loans are  not
permitted  by  the laws  or regulations  of any  state in  which its  shares are
qualified for sale and  will not lend more  than 25% of the  value of its  total
assets.  Loans  will  be  subject  to termination  by  the  Fund  in  the normal
settlement time, currently five business days  after notice, or by the  borrower
on  one day's  notice. Borrowed  securities must  be returned  when the  loan is
terminated. Any gain  or loss  in the market  price of  the borrowed  securities
which  occurs  during  the  term  of  the  loan  inures  to  the  Fund  and  its
shareholders. The Fund  may pay reasonable  finders, borrowers,  administrative,
and  custodial fees in connection with a  loan. The creditworthiness of firms to
which the Fund lends  its portfolio securities will  be monitored on an  ongoing
basis. During the fiscal year ended December 31, 1996, the Fund did not loan its
portfolio  securities  and it  has no  current intention  to loan  its portfolio
securities in the foreseeable future.
    
 
   
    WHEN-ISSUED AND DELAYED  DELIVERY SECURITIES  AND FORWARD  COMMITMENTS.   As
discussed  in  the Prospectus,  from time  to  time, in  the ordinary  course of
business, the Fund may purchase securities on a when-issued or delayed  delivery
basis  and may purchase or  sell securities on a  forward commitment basis. When
such transactions  are  negotiated,  the price  is  fixed  at the  time  of  the
commitment,  but delivery and payment  can take place a  month or more after the
date of  the commitment.  The  securities so  purchased  are subject  to  market
fluctuation  and no interest accrues to  the purchaser during this period. While
the Fund will  only purchase securities  on a when-issued,  delayed delivery  or
forward  commitment basis  with the intention  of acquiring  the securities, the
Fund may  sell  the securities  before  the settlement  date,  if it  is  deemed
advisable. At the time the Fund makes the commitment to purchase securities on a
when-issued  or delayed delivery basis, the Fund will record the transaction and
thereafter reflect the value, each day, of such security in determining the  net
asset  value of the Fund.  At the time of delivery  of the securities, the value
may be more  or less than  the purchase price.  The Fund will  also establish  a
segregated  account with the Fund's custodian bank in which it will continuously
maintain cash or U.S. Government securities or other liquid portfolio securities
equal  in  value  to  commitments  for  such  when-issued  or  delayed  delivery
securities;  subject to  this requirement, the  Fund may  purchase securities on
such basis without  limit. An increase  in the percentage  of the Fund's  assets
committed  to the  purchase of securities  on a when-issued  or delayed delivery
basis may increase the volatility of the Fund's net asset value. The  Investment
Manager  and the  Trustees do  not believe  that the  Fund's net  asset value or
income will be adversely affected by its purchase of securities on such basis.
    
 
HEDGING ACTIVITIES
 
    The Fund may enter financial futures contracts, options on such futures  and
municipal bond index futures contracts for hedging purposes.
 
FUTURES CONTRACTS AND OPTIONS ON FUTURES
 
    As  discussed in  the Prospectus, the  Fund may invest  in financial futures
contracts ("futures  contracts")  and  related options  thereon.  These  futures
contracts  and related  options thereon  will be  used only  as a  hedge against
anticipated interest rate changes. A futures contract sale creates an obligation
by the Fund, as seller, to deliver the specific type of instrument called for in
the contract  at  a specified  future  time for  a  specified price.  A  futures
contract  purchase would create an obligation by the Fund, as purchaser, to take
delivery of the specific type of financial instrument at a specified future time
at a specified price. The specific securities delivered or taken,  respectively,
at  settlement  date, would  not  be determined  until  or near  that  date. The
determination would be in accordance with the rules of the exchange on which the
futures contract sale or purchase was effected.
 
    Although the terms of futures  contracts specify actual delivery or  receipt
of  securities,  in  most instances  the  contracts  are closed  out  before the
settlement date without  the making  or taking  of delivery  of the  securities.
Closing  out  of a  futures contract  is  usually effected  by entering  into an
offsetting transaction. An offsetting transaction for a futures contract sale is
effected by the  Fund entering  into a futures  contract purchase  for the  same
aggregate  amount  of the  specific  type of  financial  instrument at  the same
delivery date. If  the price in  the sale  exceeds the price  in the  offsetting
purchase,  the Fund is immediately paid the difference and thus realizes a gain.
If the offsetting purchase price exceeds the sale
 
                                       14
<PAGE>
price,  the  Fund pays  the  difference and  realizes  the loss.  Similarly, the
closing out of a futures contract purchase is effected by the Fund entering into
a futures contract sale. If the offsetting sale price exceeds the purchase price
the Fund realizes  a gain, and  if the offsetting  sale price is  less than  the
purchase price the Fund realizes a loss.
 
    Unlike  a futures  contract, which  requires the parties  to buy  and sell a
security on a set date, an option  on a futures contract entitles its holder  to
decide  on or before a future date whether to enter into such a contract. If the
holder decides not to enter into the  contract, the premium paid for the  option
is  lost. Since the value of the option is fixed at the point of sale, there are
no daily payments of cash to reflect  the change in the value of the  underlying
contract,  as discussed  below for  futures contracts.  The value  of the option
changes and is reflected in the net asset value of the Fund.
 
    The Fund  is  required to  maintain  margin deposits  with  brokerage  firms
through  which it  effects futures  contracts and  options thereon.  The initial
margin requirements vary according  to the type of  the underlying security.  In
addition,  due to current industry practice daily variations in gains and losses
on open contracts are required to be reflected in cash in the form of  variation
margin  payments. The  Fund may be  required to make  additional margin payments
during the term of the contract.
 
    Currently, futures contracts  can be  purchased on debt  securities such  as
U.S. Treasury Bills and Bonds, U.S. Treasury Notes with maturities between 6 1/2
and  10 years, Certificates of the  Government National Mortgage Association and
Bank Certificates  of Deposit.  The Fund  may invest  in interest  rate  futures
contracts  covering these types of financial instruments as well as in new types
of contracts that become available in the future.
 
    Financial futures  contracts are  traded in  an auction  environment on  the
floors of several Exchanges--principally the Chicago Board of Trade, the Chicago
Mercantile  Exchange and the New York Futures Exchange. Each exchange guarantees
performance  under  contract  provisions  through  a  clearing  corporation,   a
nonprofit  organization  managed  by  the  exchange  membership  which  is  also
responsible for handling daily accounting of deposits or withdrawals of margin.
 
    A  risk  in  employing  futures  contracts  to  protect  against  the  price
volatility  of portfolio securities is that  the prices of securities subject to
futures contracts may correlate imperfectly with the behavior of the cash prices
of the Fund's portfolio securities. The correlation may be distorted by the fact
that the futures  market is dominated  by short-term traders  seeking to  profit
from  the difference  between a contract  or security price  objective and their
cost of borrowed funds. This would reduce their value for hedging purposes  over
a  short time period. The correlation may be further distorted since the futures
contracts that are being used to hedge are not based on municipal obligations.
 
    Another  risk  is  that  the  Fund's  manager  could  be  incorrect  in  its
expectations as to the direction or extent of various interest rate movements or
the  time span within which  the movements take place.  For example, if the Fund
sold futures contracts for the sale of securities in anticipation of an increase
in interest  rates, and  then interest  rates went  down instead,  causing  bond
prices to rise, the Fund would lose money on the sale.
 
    Put  and call options  on financial futures  have similar characteristics as
exchange-traded options. See below for a further description of options.
 
    In addition to the risks associated with investing in options on securities,
there are particular risks associated with  investing in options on futures.  In
particular,  the ability  to establish and  close out positions  on such options
will be subject to the development and maintenance of a liquid secondary market.
It is not certain that this market will develop.
 
    In order to assure  that the Fund is  entering into transactions in  futures
contracts  for  hedging purposes  as such  is defined  by the  Commodity Futures
Trading Commission either: 1) a  substantial majority (i.e., approximately  75%)
of  all anticipatory hedge transactions (transactions in which the Fund does not
own at  the time  of the  transaction, but  expects to  acquire, the  securities
underlying  the  relevant futures  contract) involving  the purchase  of futures
contracts will be completed by the purchase of
 
                                       15
<PAGE>
securities which are the subject of the hedge or 2) the underlying value of  all
long  positions in futures contracts  will not exceed the  total value of a) all
short-term debt obligations held by the Fund; b) cash held by the Fund; c)  cash
proceeds  due  to the  Fund on  investments  within thirty  days; d)  the margin
deposited on the contracts; and e)  any unrealized appreciation in the value  of
the contracts.
 
    The  Fund may not enter into futures contracts or related options thereon if
immediately thereafter the amount committed to  margin plus the amount paid  for
option premiums exceeds 5% of the value of the Fund's total assets. In instances
involving the purchase of futures contracts by the Fund, the market value of the
futures  contract will  be deposited  in a segregated  account of  cash and cash
equivalents to collateralize  the position and  thereby ensure that  the use  of
such  futures is unleveraged. The Fund may not purchase or sell futures contacts
or related options  if immediately  thereafter more  than one-third  of its  net
assets would be hedged.
 
    MUNICIPAL  BOND INDEX  FUTURES.  The  Fund may utilize  municipal bond index
futures contracts for hedging purposes. The Fund's strategies in employing  such
contracts  will be  similar to  that discussed  above with  respect to financial
futures and options thereon. A municipal bond index is a method of reflecting in
a single  number the  market value  of  many different  municipal bonds  and  is
designed  to be representative of the municipal bond market generally. The index
fluctuates in response  to changes in  the market values  of the bonds  included
within  the index. Unlike futures contracts on particular financial instruments,
transactions in futures on  a municipal bond  index will be  settled in cash  if
held until the close of trading in the contract. However, like any other futures
contract, a position in the contract may be closed out by purchase or sale of an
offsetting  contract  for the  same delivery  month prior  to expiration  of the
contract.
 
    OPTIONS.  The Fund may purchase  or sell (write) options on debt  securities
as  a means of  achieving additional return  or hedging the  value of the Fund's
portfolio. The  Fund  would  only  buy options  listed  on  national  securities
exchanges.  The Fund will  not purchase options  if, as a  result, the aggregate
cost of all outstanding options exceeds 10% of the Fund's total assets.
 
    Presently there are no options on  New York tax-exempt securities traded  on
national  securities exchanges and until such time as they become available, the
Fund will not invest in options on debt securities. It is anticipated that  such
instruments will not become available during the next year.
 
    A call option is a contract that gives the holder of the option the right to
buy  from the writer of  the call option, in return  for a premium, the security
underlying the option at a specified exercise price at any time during the  term
of the option. The writer of the call option has the obligation upon exercise of
the option to deliver the underlying security upon payment of the exercise price
during  the option period. A  put option is a contract  that gives the holder of
the option  the right  to sell  to  the writer,  in return  for a  premium,  the
underlying  security at  a specified  price during the  term of  the option. The
writer of  the  put has  the  obligation to  buy  the underlying  security  upon
exercise, at the exercise price during the option period.
 
   
    The  Fund will only write covered call  or covered put options. The Fund may
not write covered options in an amount  exceeding 20% of the value of its  total
assets.  A call  option is  "covered" if the  Fund owns  the underlying security
subject to the option  or has an  absolute and immediate  right to acquire  that
security  or  futures contract  without  additional cash  consideration  (or for
additional cash consideration  held in  a segregated account  by its  custodian)
upon  conversion or exchange of  other securities held in  its portfolio. A call
option is also covered if the Fund holds a call on the same security or  futures
contract  as the call written  where the exercise price of  the call held is (i)
equal to or less  than the exercise  price of the call  written or (ii)  greater
than  the exercise price of the call  written if the difference is maintained by
the Fund  in cash,  Treasury bills  or other  liquid portfolio  securities in  a
segregated  account with its  custodian. A put  option is "covered"  if the Fund
maintains cash, Treasury bills or other liquid portfolio securities with a value
equal to the exercise price in a segregated account with its custodian, or  else
holds  a put on the  same security or futures contract  as the put written where
the exercise price  of the put  held is equal  to or greater  than the  exercise
price of the put written.
    
 
                                       16
<PAGE>
    If  the  Fund has  written an  option,  it may  terminate its  obligation by
effecting a closing purchase transaction. This is accomplished by purchasing  an
option  of the same series  as the option previously  written. However, once the
Fund has been assigned an exercise notice,  the Fund will be unable to effect  a
closing  purchase transaction. Similarly, if the Fund is the holder of an option
it may liquidate its position by  effecting a closing sale transaction. This  is
accomplished  by selling an option  of the same series  as the option previously
purchased. There can  be no  assurance that either  a closing  purchase or  sale
transaction can be effected when the Fund so desires.
 
    The  Fund will realize a  profit from a closing  transaction if the price of
the transaction is less than the premium received from writing the option or  is
more  than the premium paid to purchase the option; the Fund will realize a loss
from a closing  transaction if the  price of  the transaction is  more than  the
premium  received from writing  the option or  is less than  the premium paid to
purchase the option. Since call option prices generally reflect increases in the
price of the underlying  security, any loss resulting  from the repurchase of  a
call option may also be wholly or partially offset by unrealized appreciation of
the underlying security. Other principal factors affecting the market value of a
put  or a  call option  include supply and  demand, interest  rates, the current
market price  and price  volatility  of the  underlying  security and  the  time
remaining until the expiration date.
 
    An  option position may be  closed out only on  an exchange which provides a
secondary market  for an  option of  the  same series.  Although the  Fund  will
generally  purchase or write only those options for which there appears to be an
active secondary market, there is no assurance that a liquid secondary market on
an exchange will exist for any particular option. In such event it might not  be
possible  to effect closing transactions in particular options, so that the Fund
would have to  exercise its options  in order  to realize any  profit and  would
incur  brokerage  commissions upon  the exercise  of call  options and  upon the
subsequent disposition of underlying securities for the exercise of put options.
If the Fund,  as a covered  call option writer,  is unable to  effect a  closing
purchase  transaction in  a secondary market,  it will  not be able  to sell the
underlying security  until the  option  expires or  it delivers  the  underlying
security upon exercise.
 
PORTFOLIO MANAGEMENT
 
   
    The Fund's portfolio turnover rate during the fiscal year ended December 31,
1996 was 16%. It is anticipated that the Fund's portfolio turnover rate will not
exceed  50% during the fiscal year ending December 31, 1997. A 50% turnover rate
would occur, for example, if 50% of the securities held in the Fund's  portfolio
(excluding all securities whose maturities at acquisition were one year or less)
were  sold  and  replaced within  one  year.  However, the  Fund  may  engage in
short-term trading consistent with its  investment objective. Securities may  be
sold in anticipation of a market decline (a rise in interest rates) or purchased
in  anticipation of a market rise (a  decline in interest rates). In addition, a
security may be  sold and another  security of comparable  quality purchased  at
approximately  the same  time to take  advantage of what  the Investment Manager
believes to be a  temporary disparity in the  normal yield relationship  between
the  two securities. These yield disparities  may occur for reasons not directly
related to the investment quality of  particular issues or the general  movement
of  interest rates,  such as changes  in the  overall demand for,  or supply of,
various types of tax-exempt securities.
    
 
    In general,  purchases  and  sales  may also  be  made  to  restructure  the
portfolio   in   terms  of   average   maturity,  quality,   coupon   yield,  or
diversification for any one or more  of the following purposes: (a) to  increase
income,  (b) to improve portfolio quality, (c) to minimize capital depreciation,
(d) to realize  gains or losses,  or for  such other reasons  as the  Investment
Manager deems relevant in light of economic and market conditions.
 
    The  Fund does  not generally intend  to invest  more than 25%  of its total
assets in  securities  of  any  one governmental  unit.  Subject  to  investment
restriction number 3 in the Prospectus, 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).
 
    The  Fund  may  invest  in  obligations  customarily  sold  to institutional
investors in private transactions with the issuers  thereof and up to 5% of  its
total   assets  in   securities  for   which  a   BONA  FIDE   market  does  not
 
                                       17
<PAGE>
exist at the time of purchase. With respect to any securities as to which a BONA
FIDE market does not exist, the Fund may be unable to dispose of such securities
promptly at reasonable prices. It is the Fund's current intention not to  invest
in such obligations.
 
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, which may not be changed without the vote of a majority of
the outstanding voting securities  of the Fund,  as defined in  the Act. Such  a
majority  is defined as the lesser of (a) 67% of the shares present at a meeting
of shareholders, if the holders  of more than 50%  of the outstanding shares  of
the  Fund  are present  or represented  by proxy  or  (b) more  than 50%  of the
outstanding shares of the Fund. For  purposes of the following restrictions  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 securities  guaranteed by  separate
entities will be considered separate securities; (b) a "taxable security" is any
security  the interest on  which is subject  to federal income  tax; and (c) all
percentage limitations apply immediately after a purchase or initial investment,
and any subsequent  change in  any applicable percentage  resulting from  market
fluctuations  or  other  changes  in  total  or  net  assets  does  not  require
elimination of any security from the portfolio.
 
    The Fund may not:
 
         1. Invest in common stock.
 
         2. Invest in securities of any issuer if, to the knowledge of the Fund,
    any officer or Trustee of the Fund or officer or director of the  Investment
    Manager  owns more  than 1/2  of 1%  of the  outstanding securities  of such
    issuer, and such officers 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  except that  the Fund  may  purchase
    financial   futures  contracts  and  related   options  in  accordance  with
    procedures adopted by the Trustees described in its Prospectus and Statement
    of Additional Information.
 
         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
    options on futures contracts or options on debt securities.
 
         7.  Purchase  securities  of  other  investment  companies,  except  in
    connection  with a  merger, consolidation, reorganization  or acquisition of
    assets.
 
         8. Borrow  money, except  that the  Fund  may borrow  from a  bank  for
    temporary  or emergency purposes  in amounts not exceeding  5% (taken at the
    lower of  cost or  current value)  of the  value of  its total  assets  (not
    including the amount borrowed).
 
         9.  Pledge its  assets or assign  or otherwise encumber  them except to
    secure  permitted  borrowings.  (For   the  purpose  of  this   restriction,
    collateral   arrangements  with  respect  to  the  writing  of  options  and
    collateral arrangements with respect to  initial margin for futures are  not
    deemed  to  be  pledges of  assets  and  neither such  arrangements  nor the
    purchase or  sale of  futures are  deemed to  be the  issuance of  a  senior
    security as set forth in restriction 10.)
 
        10.  Issue senior securities as defined in the Act except insofar as the
    Fund may  be deemed  to have  issued a  senior security  by reason  of:  (a)
    entering  into any repurchase agreement; (b)  purchasing any securities on a
    when-issued or delayed delivery basis; or (c) borrowing money in  accordance
    with restrictions described above.
 
                                       18
<PAGE>
        11.  Make loans of money  or securities, except: (a)  by the purchase of
    debt obligations in which the Fund may invest consistent with its investment
    objective and policies; (b) by investment in repurchase agreements; and  (c)
    by lending its portfolio securities.
 
        12. Make short sales of securities.
 
        13.  Purchase securities on margin, except  for such short-term loans as
    are necessary for the  clearance of purchases  of portfolio securities.  The
    deposit  or payment by the Fund of initial or variation margin in connection
    with futures  contracts or  related options  thereon is  not considered  the
    purchase of a security on margin.
 
       14.  Engage in the underwriting of securities, except insofar as the Fund
    may  be deemed an underwriter under the  Securities Act of 1933 in disposing
    of a portfolio security.
 
       15.  Invest for  the purpose of exercising  control or management of  any
    other issuer.
 
PORTFOLIO TRANSACTIONS AND BROKERAGE
- --------------------------------------------------------------------------------
 
   
    The  Investment  Manager  is  responsible  for  decisions  to  buy  and sell
securities and commodities 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 charging a stated commission,
although the price  of the  security usually includes  a profit  to the  dealer.
Options and futures transactions will usually be effected through a broker and a
commission  will  be charged.  The  Fund also  expects  that securities  will be
purchased at times in  underwritten offerings where the  price includes a  fixed
amount of compensation, generally referred to as the underwriter's concession or
discount.  On  occasion,  the  Fund  may  also  purchase  certain  money  market
instruments directly from an issuer, in  which case no commissions or  discounts
are  paid. During the fiscal  years ended December 31,  1994, 1995 and 1996, the
Fund did not pay any brokerage commissions.
    
 
   
    The Investment Manager currently serves as investment manager to a number of
clients, including other  investment companies,  and may  in the  future act  as
investment  manager or adviser to  others. It is the  practice of the Investment
Manager to cause purchase and sale  transactions to be allocated among the  Fund
and  others whose  assets it manages  in such  manner as it  deems equitable. In
making such  allocations  among the  Fund  and other  client  accounts,  various
factors  are  considered, including  the  respective investment  objectives, the
relative size of portfolio  holdings of the same  or comparable securities,  the
availability  of  cash  for  investment,  the  size  of  investment  commitments
generally held and  the opinions  of the  persons responsible  for managing  the
portfolios of the Fund and other client accounts. In the case of certain initial
and  secondary public offerings,  the Investment Manager  may utilize a pro-rata
allocation process based on the size of  the Dean Witter Funds involved and  the
number of shares available from the public offering.
    
 
    The  policy of the Fund, regarding purchases and 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
 
                                       19
<PAGE>
not,  in  every case,  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 will
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.  Such transactions will be  effected
with  DWR only when the  price available from DWR  is better than that available
from other dealers.
 
    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  arms-length transaction.  Furthermore, the  Trustees of  the Fund,
including a majority  of the Trustees  who are not  "interested" Trustees,  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.
 
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.   The national economic downturn which began in July 1990 adversely
affected the  local economy,  which had  been declining  since late  1989. As  a
result,  New York City (the "City") experienced  job losses in 1990 and 1991 and
real Gross City Product (GCP) fell in those two years. For the 1992 fiscal year,
the City closed a  projected budget gap  of $3.3 billion in  order to achieve  a
balanced  budget as required  by the laws  of the State.  Beginning in 1992, the
improvement in the  national economy  helped stabilize conditions  in the  City.
Employment  losses moderated toward year-end and  real GCP increased, boosted by
strong wage gains. After  noticeable improvements in  the City's economy  during
calendar  year  1994, economic  growth slowed  in 1995,  and the  City's current
four-year financial plan  assumes that  moderate economic  growth will  continue
through the year 2000.
    
 
   
    For  each of the 1981 through 1996  fiscal years, the City achieved balanced
operating results  as  reported in  accordance  with then  applicable  generally
accepted  accounting  principles  ("GAAP").  The  City  was  required  to  close
substantial budget gaps in recent years in order to maintain balanced  operating
results.
    
 
   
    1997-2000  NEW  YORK CITY  FINANCIAL  PLAN.   The  Mayor is  responsible for
preparing the City's four-year financial  plan (the "1997-2000 Financial  Plan",
the "Financial Plan" or "City Plan").
    
 
   
    On  November 14, 1996, the City submitted to the Control Board the Financial
Plan for the 1997-2000 fiscal years, which is a modification to a financial plan
submitted to the Control Board on June 21, 1996 (the "June Financial Plan")  and
which  relates  to  the  City,  the Board  of  Education  ("BOE")  and  the City
University of New York.
    
 
                                       20
<PAGE>
   
    The June Financial  Plan set forth  proposed actions to  close a  previously
projected gap of approximately $2.6 billion for the 1996 fiscal year, including:
(i)  agency actions totaling $1.2 billion;  (ii) a revised tax reduction program
which would increase projected tax revenues by $369 million due to the four year
extension of the 12.5%  personal income tax surcharge  and other actions;  (iii)
savings  resulting from cost containment in  entitlement programs to reduce City
expenditures and additional proposed State aid of $74 million; (iv) the  assumed
receipt of revenues relating to rent payments for the City's airports, which are
currently  the subject of a dispute with the  Port Authority of New York and New
Jersey (the "Port Authority"); (v) the sale of the City's television station for
$207 million; and (vi) pension cost savings totaling $134 million resulting from
a proposed increase in the earnings  assumption for pension assets from 8.5%  to
8.75%.
    
 
   
    The  1997-2000 Financial Plan published on November 14, 1996 reflects actual
receipts and  expenditures and  changes in  forecast revenues  and  expenditures
since  the June Financial  Plan. The 1997-2000  Financial Plan projects revenues
and expenditures for  1997 fiscal  year balanced  in accordance  with GAAP,  and
projects  gaps of $1.2 billion, $2.1 billion and $3.0 billion for the 1998, 1999
and 2000  fiscal years,  respectively.  Changes since  the June  Financial  Plan
include:  (i)  an  increase in  projected  tax  revenues of  $450  million, $120
million, $50  million  and  $45  million in  fiscal  years  1997  through  2000,
respectively;  (ii) a delay in  the assumed receipt of  $304 million relating to
projected rent payments for the City airports  from the 1997 fiscal year to  the
1998  and 1999 fiscal  years, and a  $34 million reduction  in assumed State and
Federal aid for the 1997 fiscal year; (iii) an approximate $200 million increase
in projected overtime and  other expenditures in each  of the fiscal years  1997
through  2000; (iv) a $70  million increase in expenditures  for BOE in the 1997
fiscal year for school text books; (v) a reduction in projected pension costs of
$34 million,  $50 million,  $49 million  and $47  million in  fiscal years  1997
through  2000, respectively;  and (vi)  additional agency  actions totaling $179
million, $386  million, $473  million  and $589  million  in fiscal  years  1997
through 2000, respectively, including personnel reductions through attrition and
early retirement.
    
 
   
    The City depends on the State for aid both to enable the City to balance its
budget  and to meet its cash requirements.  There can be no assurance that there
will not be reductions in State aid to the City from amounts currently projected
or that the State budgets in future fiscal years will be adopted by the April  1
statutory  deadline and  that such  reductions or  delays will  not have adverse
effects on the City's cash flow or expenditures.
    
 
   
    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
condition  of the regional  and local economies,  the impact on  real estate tax
revenues of the real estate market, wage increases for City employees consistent
with those assumed  in the  Financial Plan,  employment growth,  the ability  to
implement  proposed  reductions  in  City  personnel  and  other  cost reduction
initiatives, which may require  in certain cases the  cooperation of the  City's
municipal  unions,  the  ability  of  the New  York  City  Health  and Hospitals
Corporations and BOE to take actions to offset reduced revenues, the ability  to
complete revenue generating transactions, provision of State and Federal aid and
mandate  relief and  the impact  on City revenues  of proposals  for Federal and
State welfare  reform and  any future  legislation affecting  Medicare or  other
entitlement.
    
 
   
    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  1997 through 2000 contemplates the  issuance
of  $7.7 billion  of general obligation  bonds and  $4.5 billion of  bonds to be
issued by the proposed New  York City Infrastructure Finance Authority  ("IFA"),
primarily to reconstruct and rehabilitate the City's infrastructure and physical
assets and to make other capital investments. The creation of the IFA is subject
to  the enactment of State legislation. In addition, the 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 and IFA Bonds will  be
subject to prevailing market conditions, and
    
 
                                       21
<PAGE>
   
no  assurance can be given  that such sales will be  completed. If the City were
unable to sell its general obligation bonds  and notes or bonds of the  proposed
IFA,  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. It  is reasonable  to expect that  such reports and
statements will continue to be issued and to engender public comment.
    
 
   
    RATINGS.
    
 
   
    Moody's has  rated the  City's  general obligation  bonds Baa1.  Standard  &
Poor's  has rated the bonds BBB+. Fitch has  rated the bonds A-. On February 28,
1996, Fitch  placed  the City's  general  obligation bonds  on  FitchAlert  with
negative  implications. On  November 5, 1996,  Fitch removed  the City's general
obligation bonds from FitchAlert, although Fitch stated that the outlook remains
negative. These  ratings do  not  reflect any  bond  insurance relating  to  any
portion  of the bonds. The  city expects that ratings  on the Financial Guaranty
Insured Bonds and the AMBAC Insured Bonds  will be received prior to January  7,
1997.  The ratings on the Financial Guaranty Insured Bonds and the AMBAC Insured
Bonds will be based on the insurance policies to be issued by Financial Guaranty
and AMBAC  Indemnity,  respectively.  Bonds insured  to  maturity  by  Financial
Guaranty  are rated "AAA"  by Standard &  Poor's, "Aaa" by  Moody's and "AAA" by
Fitch. Bonds insured to maturity by AMBAC Indemnity are rated "AAA" by  Standard
&  Poor's, "Aaa" by  Moody's and "AAA"  by Fitch. Such  ratings reflect only the
views of Moody's, Standard & Poor's and Fitch, 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 not  be
revised downward or withdrawn entirely. Any such downward revision or withdrawal
could have an adverse effect on the market prices of the bonds.
    
 
    OUTSTANDING INDEBTEDNESS
 
   
    As  of September 30, 1996, the City and the Municipal Assistance Corporation
for the City of New York  had, respectively, $25.099 billion and $3.889  billion
of outstanding net long-term debt.
    
 
   
    LITIGATION.   The  City is  a defendant  in lawsuits  pertaining to material
matters, including claims  asserted which are  incidental to performing  routine
governmental  and other functions. This litigation  includes, but is not limited
to, actions  commenced and  claims  asserted against  the  City arising  out  of
alleged  torts, alleged  breaches of  contracts, alleged  violations of  law and
condemnation proceedings. As of June 30, 1996 and 1995, claims in excess of $380
billion and $311 billion,  respectively, were outstanding  against the City  for
which  the City estimates its potential future  liability to be $2.8 billion and
$2.5 billion, respectively.
    
 
NEW YORK STATE
 
   
    RECENT DEVELOPMENTS.  The national economy has resumed a more robust rate of
growth after  a  "soft  landing"  in  1995, with  over  11  million  jobs  added
nationally  since early  1992. The  State economy  has continued  to expand, but
growth remains somewhat slower than in the nation. Although the State has  added
approximately  240,000 jobs since late 1992,  employment growth in the State has
been hindered during recent  years by significant cutbacks  in the computer  and
instrument  manufacturing, utility,  defense and  banking industries. Government
downsizing has also moderated these job gains.
    
 
   
    The 1996-97  New York  State  Financial Plan  (the  "State Plan")  or  "July
Financial  Plan" is based on the State's economy showing modest expansion during
the first half of 1996,  but that some slowdown  is projected during the  second
half  of  the  year. Although  industries  that  export goods  and  services are
expected to continue to do well, growth  is expected to be slowed by  government
cutbacks  at all  levels and  by tight fiscal  constraints on  health and social
services. On an average annual basis, employment growth in the State is expected
to be up  slightly from the  1995 rate.  Personal income is  expected to  record
moderate  gains in 1996. Bonus payments  in the securities industry are expected
to increase further from last year's record level.
    
 
                                       22
<PAGE>
   
    The State  Plan is  based  upon forecasts  of  national and  State  economic
activity  developed  through  both internal  analysis  and review  of  State and
national economic  forecasts prepared  by  commercial forecasting  services  and
other  public and private forecasters. Economic forecasts have frequently failed
to predict accurately the  timing and magnitude of  changes in the national  and
the  State economies. Many uncertainties exist in forecasts of both the national
and State economies, including consumer attitudes toward spending, the extent of
corporate and governmental restructuring, federal fiscal and monetary  policies,
the level of interest rates, 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  results in the current  fiscal year that are  worse
than  predicted, with corresponding material and  adverse effects on the State's
projections of receipts and disbursements.
    
 
   
    THE 1996-97 FISCAL YEAR.  The State's General Fund (the major operating fund
of the State) was projected in the State Plan to be balanced on a cash basis for
the 1996-97 fiscal  year. The  State Plan  projected General  Fund receipts  and
transfers  from other funds at $33.17 billion,  an increase of $365 million from
the prior fiscal year, and disbursements and transfers to other funds at  $33.12
billion,  an increase  of $444  million from  the total  disbursed in  the prior
fiscal year.
    
 
   
    The State issued its first update to the State Plan (the "Mid-Year  Update")
on  October 25, 1996. The Mid-Year  Update projects a continued balanced 1996-97
State Financial Plan, with  a reserve for contingencies  in the General Fund  of
$300  million.  This  reserve will  be  utilized  to help  offset  a  variety of
potential risks  and other  unexpected  contingencies that  the State  may  face
during  the balance  of the  1996-97 fiscal  year. The  Mid-Year Update reflects
revisions made to  estimates of both  receipts and disbursements  based on:  (1)
updated economic forecasts for both the nation and the State, (2) an analysis of
actual  receipts and  disbursements through the  first six months  of the fiscal
year, and (3) an assessment of changing State program requirements.
    
 
   
    More specifically, based on the revised economic outlook and actual receipts
for the first  six months of  1996-97, projected General  Fund receipts for  the
1996-97  State fiscal  year have  been increased by  $420 million.  Most of this
projected increase is in  the yield of the  personal income tax ($241  million),
with  additional increases  now expected  in business  taxes ($124  million) and
other tax receipts ($49 million). Projected collections from user taxes and fees
have been revised downward  slightly ($5 million). Revisions  were also made  to
both  miscellaneous receipts and  in transfers from other  funds (an $11 million
combined projected increase).
    
 
   
    Disbursements through the  first six  months of  the fiscal  year were  $415
million  less than projected, primarily because of delays in processing payments
following delayed enactment  of the State  budget. As a  result, no savings  are
included  in  the  Mid-Year  Update  from  this  slower-than-expected  spending.
Projections of 1996-97 General Fund disbursements are increased by $120 million,
since increased General Fund disbursements for education are required to replace
a projected decrease in lottery receipts.
    
 
   
    Revisions to  all governmental  funds receipts  and disbursements  estimates
primarily  reflect changes to the General Fund and transfers between fund types.
The projected closing fund balance for  all governmental funds is $623  million,
unchanged from the projection in the State Plan. The annual increase in spending
for  all  governmental  funds  remains  approximately  4  percent,  the  same as
projected in the State Plan.
    
 
   
    Uncertainties with regard to the economy, as well as the outcome of  certain
litigation  now pending against the State,  could produce adverse effects on the
projections of receipts and disbursements  in the Mid-Year Update. For  example,
changes  to current  levels of  interest rates  or deteriorating  world economic
conditions could have an adverse effect on the State economy and produce results
in the current fiscal year that are worse than predicted. Similarly, an  adverse
judgment in legal proceedings against the State could exceed amounts reserved in
the  1996-97 Financial Plan for payment of such judgments and produce additional
unbudgeted costs to the State.

    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 June 30, 1995, LGAC issued bonds and notes to provide net proceeds  of
$4.7  billion, completing  the program. The  impact of  this borrowing, together
with the availability of certain cash  reserves is that the State Plan  includes
no seasonal short-term borrowing.
 
   
    COMPOSITION  OF  STATE GOVERNMENTAL  FUNDS GROUP.   Substantially  all State
non-pension financial operations are accounted  for in the State's  governmental
funds  group. Governmental funds  include: (i) the  General Fund, which receives
all income not required  by law to  be deposited in  another fund; (ii)  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;  (iii) Capital Projects  Funds, used to finance
the acquisition, construction and rehabilitation of major capital facilities  by
the  State and to aid in certain of such projects conducted by local governments
or public  authorities; and  (iv) 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.
    
 
   
    AUTHORITIES.   The fiscal  stability of the  State is related  to the fiscal
stability of its public authorities  (i.e. public benefit corporations,  created
pursuant  to  State law,  other than  local  authorities), which  generally have
responsibility  for  financing,  constructing  and  operating  revenue-producing
public  benefit facilities.  The State's public  authorities (the "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, 1995, there  were 17 Authorities that  had outstanding debt of
$100 million or  more and  the aggregate outstanding  debt, including  refunding
bonds, of these 17 Authorities was $73.45 billion.
    
 
   
    Authorities  are generally supported  by revenues generated  by the projects
financed or operated, such  as fares, user fees  on bridges or tunnels,  highway
tolls  and  rentals  for  dormitory  rooms and  housing  units  and  charges for
occupancy at medical care facilities. In addition, State legislation  authorizes
several   financing  techniques  for  Authorities.  Also,  there  are  statutory
arrangements providing for State local assistance payments otherwise payable  to
localities  to be made under certain  circumstances to Authorities. Although the
State has no  obligation to  provide additional assistance  to localities  whose
local   assistance  payments   have  been   paid  to   Authorities  under  these
arrangements, if local assistance payments are diverted the affected  localities
could  seek additional  State assistance.  Some Authorities  also receive moneys
from State appropriations  to pay for  the operating costs  of certain of  their
programs.
    
 
   
    RATINGS.   On January 13, 1992, Standard & Poor's reduced its ratings on the
State's general obligation  bonds from  A to A-  and, in  addition, reduced  its
ratings  on  the  State's  moral  obligation,  lease  purchase,  guaranteed  and
contractual obligation  debt.  Standard &  Poor's  also continued  its  negative
rating  outlook assessment on State general  obligation debt. On April 26, 1993,
Standard & Poor's revised the rating  outlook assessment to stable. On  February
14,  1994, Standard  & Poor's raised  is outlook  to positive and,  on August 5,
1996,   confirmed   its    A-   rating.    On   January    6,   1992,    Moody's
    
 
                                       24
<PAGE>
   
Investors  Service reduced  its ratings  on outstanding  limited-liability State
lease purchase and  contractual obligations from  A to Baa1.  On July 26,  1996,
Moody's  Investors  Service  reconfirmed its  A  rating on  the  State's general
obligation long-term indebtedness. 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,  1996, the State had  outstanding
approximately  $5.05 billion in general obligation bonds, including $294 million
in bond anticipation notes  outstanding. Principal and  interest due on  general
obligation  bonds and interest due on  bond anticipation notes were $735 million
for the 1995-96  fiscal years,  and are  estimated to  be $719  million for  the
State's 1996-97 fiscal year.
    
 
   
    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.
These proceedings could affect adversely the financial condition of the State in
the 1996-1997 Fiscal Year or thereafter.
    
 
   
    The  State  believes  that  the  1995-1996  State  Financial  Plan  includes
sufficient reserves for the payment of judgments that may be required during the
1996-1997 fiscal  year. There  can be  no assurance,  however, that  an  adverse
decision  in  any  of these  proceedings  would  not exceed  the  amount  of the
1996-1997 Financial Plan reserves for  the payment of judgments and,  therefore,
could  affect the ability  of the State  to maintain a  balanced 1996-1997 State
Financial Plan. In its  audited financial statements for  the fiscal year  ended
March  31,  1996, the  State reported  its estimated  liability for  awarded and
unanticipated unfavorable judgments at $474 million.
    
 
   
    In addition, the State  is party to other  claims and litigations which  its
counsel  has advised are  not probable of adverse  court decisions. Although the
amounts of potential losses, if any,  are not presently determinable, it is  the
State's  opinion that its ultimate  liability in these cases  is not expected to
have a  material  adverse  effect  on the  State's  financial  position  in  the
1996-1997 fiscal year or thereafter.
    
 
   
    OTHER  LOCALITIES.   Certain localities in  addition to the  City could have
financial problems leading  to requests for  additional State assistance  during
the  State's 1996-97  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 1996-97 fiscal year.
    
 
   
    For  example,  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  in 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
increased state expenditures for extra ordinary local assistance.
    
 
THE DISTRIBUTOR
- --------------------------------------------------------------------------------
 
   
    As discussed in the Prospectus, shares  of the Fund are distributed by  Dean
Witter  Distributors  Inc.  (the  "Distributor"),  on  a  continuous  basis. The
Distributor has entered into a selected dealer agreement with DWR, which through
its own sales organization sells shares of the Fund and may enter into  selected
dealer  agreements with other selected  dealers ("selected broker-dealers"). The
Distributor, a Delaware corporation, is  a wholly-owned subsidiary of DWDC.  The
Trustees,  including a majority of the Trustees who  are not and were not at the
time they voted "interested  persons" of the  Fund, as defined  in the Act  (the
"Independent  Trustees"), at  a meeting  held on  October 30,  1992 approved the
current Distribution
    
 
                                       25
<PAGE>
   
Agreement appointing  the Distributor  as exclusive  distributor of  the  Fund's
shares and providing for the Distributor to bear distribution expenses not borne
by  the Fund. The  current Distribution Agreement  is substantively identical to
the Fund's previous distribution agreement in all material respects, except  for
the  dates of effectiveness.  The current 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 had  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.  At their meeting  held on April 17,
1996, the  Trustees, including  all of  the Independent  Trustees, approved  the
continuation of the Distribution Agreement until April 30, 1997.
    
 
    The  Distributor bears all expenses incurred in providing services under the
Distribution Agreement. Such  expenses include  the payment  of commissions  for
sales of the Fund's shares and incentive compensation to account executives. The
Distributor  also pays certain  expenses in connection  with the distribution of
the Fund's shares, including the  costs of preparing, printing and  distributing
advertising or promotional materials, and the costs of printing and distributing
prospectuses  and supplements thereto  used in connection  with the offering and
sale of the Fund's shares to other than current shareholders. The Fund bears the
costs of  initial typesetting,  printing and  distribution of  prospectuses  and
supplements   thereto  to  shareholders.  The  Fund  also  bears  the  costs  of
registering the Fund and its shares under federal and state securities laws. The
Fund and the  Distributor have agreed  to indemnify each  other against  certain
liabilities, including liabilities under the Securities Act of 1933, as amended.
Under  the  Distribution Agreement,  the Distributor  uses  its best  efforts in
rendering services to the Fund, but  in the absence of willful misfeasance,  bad
faith,   gross  negligence  or  reckless   disregard  of  its  obligations,  the
Distributor is not liable to the Fund  or any of its shareholders for any  error
of  judgment or  mistake of law  or for  any act or  omission or  for any losses
sustained by the Fund or its shareholders.
 
PLAN OF DISTRIBUTION
 
   
    To compensate the Distributor for the services provided and for the expenses
borne  by  the  Distributor  or  any  selected  dealer  under  the  Distribution
Agreement,  the Fund has adopted  a Plan of Distribution  pursuant to Rule 12b-1
under the  Act (the  "Plan") pursuant  to which  the Fund  pays the  Distributor
compensation  accrued daily and payable  monthly at the annual  rate of 0.75% of
the lesser of: (a) the average daily aggregate gross sales of the Fund's  shares
since  the inception  of the Fund  (not including reinvestments  of dividends or
capital gains distributions), less the  average daily aggregate net asset  value
of the Fund's shares redeemed since the Fund's inception upon which a contingent
deferred  sales  charge has  been imposed  or  upon which  such charge  has been
waived, or (b)  the average daily  net assets of  the Fund. An  amount equal  to
0.20%  of the Fund's average  annual net assets of the  fees payable by the Fund
each year pursuant to  the Plan of Distribution  is characterized as a  "service
fee"  under the Rules of Fair Practice of the National Association of Securities
Dealers, Inc. (of which the Distributor is a member). Such fee is a payment made
for personal  service  and/or  the  maintenance  of  shareholder  accounts.  The
remaining  portion of the Plan of Distribution  fee payments made by the Fund is
characterized as  an  "asset-based sales  charge"  as  such is  defined  by  the
aforementioned  Rules  of  Fair  Practice.  The  Distributor  also  receives the
proceeds of contingent deferred sales charges imposed on certain redemptions  of
shares,  which are separate  and apart from  payments made pursuant  to the Plan
(see "Redemptions  and Repurchases--Contingent  Deferred  Sales Charge"  in  the
Prospectus).  The Distributor has informed the  Fund that it and/or DWR received
contingent deferred sales  charges on redemptions  of the Fund's  shares in  the
approximate  amounts of  $312,000, $337,000  and $224,082  for the  fiscal years
ended December  31, 1994,  1995  and 1996,  respectively (see  "Redemptions  and
Repurchases--Contingent Deferred Sales Charge" in the Prospectus).
    
 
    The  Plan was adopted by a majority vote of the Board of Trustees, including
all of the Trustees of the Fund 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 the Plan  (the "Independent 12b-1 Trustees"),  cast in person at  a
meeting  called for the purpose of voting on  the Plan, on February 13, 1985, by
DWR, the  then sole  shareholder of  the Fund,  on March  20, 1985,  and by  the
shareholders  holding  a majority,  as defined  in the  Act, of  the outstanding
voting securities of the Fund at a  Meeting of Shareholders of the Fund held  on
 
                                       26
<PAGE>
April  29, 1986. Under its  terms, the Plan had  an initial term ending December
31, 1985,  and  provides  that it  will  remain  in effect  from  year  to  year
thereafter,  provided such  continuance is  approved annually  by a  vote of the
Trustees in the manner described above.
 
   
    Most recent continuation of the Plan for one year, until April 30, 1997, was
approved by the  Board of  Trustees of  the Fund,  including a  majority of  the
Independent  12b-1 Trustees, at a Board meeting held on April 17, 1996. Prior to
approving the continuation of  the Plan, the Board  requested and received  from
DWR  and reviewed all the information which  it deemed necessary to arrive at an
informed determination. In making their determination to continue the Plan,  the
Trustees  considered: (1) the Fund's experience  under the Plan and whether such
experience indicates that the Plan is operating as anticipated; (2) the benefits
the Fund had obtained,  was obtaining and  would be likely  to obtain under  the
Plan; and (3) what services had been provided and were continuing to be provided
under  the Plan by the Distributor to  the Fund and its shareholders. Based upon
their review, the Trustees of the Fund, including each of the Independent  12b-1
Trustees, determined that continuation of the Plan would be in the best interest
of  the Fund and would have a reasonable likelihood of continuing to benefit the
Fund and its shareholders. This determination  was based upon the conclusion  of
the  Trustees that the Plan provides an  effective means of stimulating sales of
shares of  the  Fund  and  of  reducing or  avoiding  net  redemptions  and  the
potentially adverse effects that may occur therefrom. In the Trustees' quarterly
review  of the  Plan, they will  consider its continued  appropriateness and the
level of compensation provided therein.
    
 
    At their  meeting  held on  October  30, 1992,  the  Trustees of  the  Fund,
including  all of the Independent 12b-1 Trustees, approved certain amendments to
the Plan which took  effect in January,  1993 and were  designed to reflect  the
fact  that  upon  the  reorganization  described  above  the  share distribution
activities theretofore  performed  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 DWR as before the amendment, and that the Distributor in turn  is
authorized   to  make  payments  to  DWR,   its  affiliates  or  other  selected
broker-dealers (or  direct  that  the  Fund pay  such  entities  directly).  The
Distributor  is also authorized to  retain part of such  fee as compensation for
its own distribution-related expenses. At their meeting held on April 28,  1993,
the  Trustees,  including a  majority of  the  Independent 12b-1  Trustees, also
approved certain technical amendments to the Plan in connection with  amendments
adopted  by the National Association of Securities  Dealers, Inc. to its Rule of
Fair Practice.
 
    At their  meeting  held on  October  26, 1995,  the  Trustees of  the  Fund,
including  all of the  Independent 12b-1 Trustees, approved  an amendment to the
Plan to  permit payments  to be  made under  the Plan  with respect  to  certain
distribution  expenses incurred in  connection with the  distribution of shares,
including personal services  to shareholders  with respect to  holdings of  such
shares,  of an  investment company whose  assets are  acquired by the  Fund in a
tax-free reorganization.
 
   
    Under the  Plan and  as required  by Rule  12b-1, the  Trustees receive  and
review promptly after the end of each calendar quarter a written report provided
by  the Distributor of the  amounts expended under the  Plan and the purpose for
which such expenditures were made. The Fund accrued amounts payable to DWR under
the Plan, during the  fiscal year ended December  31, 1996, of $1,518,807.  This
amount  is equal to payments required to be  paid monthly by the Fund which were
computed at the  annual rate of  0.75% of the  average daily net  assets of  the
Fund's  shares for the fiscal year and  was calculated pursuant to clause (b) of
the compensation formula under the Plan. This  amount is treated by the Fund  as
an expense in the year it is accrued.
    
 
    The  Plan was adopted  in order to  permit the implementation  of the Fund's
method of distribution. Under  this distribution method shares  of the Fund  are
sold  without a sales load  being deducted at the time  of purchase, so that the
full amount of an investor's purchase payment will be invested in shares without
any deduction  for  sales charges.  Shares  of the  Fund  may be  subject  to  a
contingent deferred sales charge, payable to the Distributor, if redeemed during
the  six years after  their purchase. DWR compensates  its account executives by
paying   them,   from   its   own   funds,   commissions   for   the   sale   of
 
                                       27
<PAGE>
   
the Fund's shares, currently a gross sales credit of up to 4% of the amount sold
and  an annual gross residual  of up to 0.20  of 1% of the  current value of the
respective accounts for which they are the account executives of record and  for
which they provide personal service and/or the maintenance of such accounts. The
gross  sales  credit is  a  charge which  reflects  commissions paid  to account
executives and Fund  associated distribution-related  expenses, including  sales
compensation, and overhead and other branch office distribution-related expenses
including  (a) the expenses of operating DWR's branch offices in connection with
the sale  of Fund  shares,  including lease  costs,  the salaries  and  employee
benefits   of   operations   and  sales   support   personnel,   utility  costs,
communications costs and the costs of stationery and supplies, (b) the costs  of
client  sales seminars, (c) travel expenses of mutual fund sales coordinators to
promote the  sale of  Fund shares  and  (d) other  expenses relating  to  branch
promotion of Fund sales. The distribution fee that the Distributor receives from
the  Fund under the  Plan, in effect, offsets  distribution expenses incurred on
behalf of the Fund and its opportunity costs, such as the gross sales credit and
an assumed interest  charge thereon  ("carrying charge").  In the  Distributor's
reporting  of  its  distribution expenses  to  the Fund,  such  assumed interest
(computed at the "broker's  call rate") has been  calculated on the gross  sales
credit  as it is reduced  by amounts received by  the Distributor under the Plan
and any  contingent deferred  sales  charges received  by the  Distributor  upon
redemption  of shares  of the Fund.  No other  interest charge is  included as a
distribution expense in the Distributor's calculation of its distribution  costs
for  this  purpose. The  broker's  call rate  is  the interest  rate  charged to
securities brokers on loans secured by exchange-listed securities.
    
 
   
    The Fund paid 100% of the $1,518,807  accrued under the Plan for the  fiscal
year  ended Decembers  31, 1996  to the  Distributor of  the Fund's  shares. The
Distributor and DWR estimate that they  have spent $19,765,770, pursuant to  the
Plan,  on behalf of  the Fund since the  inception of the  Fund. It is estimated
that this  amount was  spent in  approximately the  following ways:  (i)  12.49%
($2,468,549)--    advertising    and    promotional    expenses;    (ii)   1.22%
($240,294)--printing of  prospectuses for  distribution  to other  than  current
shareholders;  and  (iii)  86.29% ($17,056,927)--other  expenses,  including the
gross sales  credit  and  the  carrying charge,  of  which  10.08%  ($1,719,232)
represents  carrying charges, 36.47%  ($6,220,969) represents commission credits
to DWR branch  offices for  payments of  commissions to  account executives  and
53.45%  ($9,116,726) represents  overhead and other  branch office distribution-
related expenses.
    
 
   
    At any given time,  expenses may be incurred  in distributing shares of  the
Fund  which may be more or  less than the total of  (i) the payments made by the
Fund pursuant to  the Plan and  (ii) the proceeds  of contingent deferred  sales
charges paid by investors upon redemption of shares. The Distributor has advised
the  Fund that  such excess  amount, including  the carrying  charge designed to
approximate the opportunity costs incurred  which arise from it having  advanced
monies  without having received the  amount of any sales  charges imposed at the
time of sale of the Fund's shares, totalled $2,741,726 as of December 31,  1996.
Because  there  is  no  requirement  under  the  Plan  that  the  Distributor be
reimbursed for all its  expenses or any requirement  that the Plan be  continued
from  year to year,  this excess amount  does not constitute  a liability of the
Fund. Although  there  is no  legal  obligation for  the  Fund to  pay  expenses
incurred  by the Distributor in excess of payments made to it under the Plan and
the proceeds  of  contingent  deferred  sales charges  paid  by  investors  upon
redemption  of shares, if  for any reason  the Plan is  terminated, the Trustees
will consider at  that time  the manner  in which  to treat  such expenses.  Any
cumulative  expenses incurred by the Distributor,  but not yet recovered through
distribution fees  or contingent  deferred  sales charges,  may  or may  not  be
recovered through future distribution fees or contingent deferred sales charges.
    
 
    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, has any direct  financial
interest  in the operation of the Plan except to the extent that the Distributor
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.
 
    The Plan may not be  amended to increase materially  the amount to be  spent
for  the services described therein without  approval by the shareholders of the
Fund, and all material amendments to the

Plan must also be approved  by the Trustees in  the manner described above.  The
Plan may be terminated at any time, without payment of any penalty, by vote of a
majority  of the Independent  12b-1 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  thirty days' written notice to any other party to the Plan. So long as the
Plan is in  effect, the election  and nomination of  Independent 12b-1  Trustees
shall be committed to the discretion of the Independent 12b-1 Trustees.
 
DETERMINATION OF NET ASSET VALUE
 
    As  discussed in the Prospectus, portfolio securities (other than short-term
debt securities and futures and options) are  valued for the Fund by an  outside
independent  pricing  service approved  by the  Board  of Trustees.  The pricing
service has informed the Fund that in valuing the Fund's portfolio securities it
uses both a computerized grid matrix of tax-exempt securities and evaluations by
its staff, in each case based on information concerning market transactions  and
quotations  from dealers which reflect the bid  side of the market each day. The
Fund's portfolio securities  are thus valued  by reference to  a combination  of
transactions  and quotations  for the  same or  other securities  believed to be
comparable in quality, coupon, maturity, type of issue, call provisions, trading
characteristics and other features deemed to be relevant. The Board of  Trustees
believes  that timely and  reliable market quotations  are generally not readily
available to the Fund for purposes of valuing tax-exempt securities and that the
valuations supplied by the pricing service, using the procedures outlined  above
and subject to periodic review, are more likely to approximate the fair value of
such  securities. The net asset value of shares of the Fund is not calculated on
such federal and  non-federal holidays  as are observed  by the  New York  Stock
Exchange. 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 Investment Manager will periodically review and evaluate the procedures,
methods and quality of services provided by the pricing service then being  used
by  the Fund and may, from time to  time, recommend to the Board of Trustees the
use of  other pricing  services or  discontinuance  of the  use of  any  pricing
service in whole or part. The Board may determine to approve such recommendation
or  to make  other provisions  for pricing  of the  Fund's portfolio securities.
Short-term taxable debt securities with sixty days or less remaining to maturity
at time of purchase  are valued at amortized  cost, unless the Board  determines
such does not reflect the securities' fair value, in which case these securities
will be valued at their fair value as determined by the Board of Trustees. Other
short-term  taxable debt  securities will  be valued on  a mark  to market basis
until such time as they have a remaining maturity of sixty days, whereupon  they
will  be valued at amortized  cost using their value on  the 61st day unless the
Trustees determine such value does not reflect the securities' market value,  in
which  case  these securities  will  be valued  at  their fair  market  value as
determined by the Trustees. Listed options on debt securities are valued at  the
latest  sale price on the  exchange on which they are  listed unless no sales of
such options have taken place  that day, in which case,  they will be valued  at
the  mean between their closing  bid and asked prices.  Unlisted options on debt
securities are  valued at  the mean  between  the latest  bid and  asked  price.
Futures  contracts and options thereon which are traded on commodities exchanges
are valued at their latest sale  price on such commodities exchanges unless  the
Trustees determine that such price does not reflect their market value, in which
case  they will be valued at their fair value as determined by the Trustees. All
other securities, including illiquid securities, and other assets are valued  at
their fair value as determined in good faith under procedures established by and
under the supervision of the Board of Trustees.
 
SHAREHOLDER SERVICES
- --------------------------------------------------------------------------------
 
    Upon the purchase of shares of the Fund, a Shareholder Investment Account is
opened  for the investor on  the books of the Fund  and 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
 
                                       29
<PAGE>
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, the shareholder  will be mailed  a
statement reflecting the status of such Account.
 
    AUTOMATIC  INVESTMENT  OF DIVIDENDS  AND DISTRIBUTIONS.    As stated  in the
Prospectus,  all   income  dividends   and  capital   gains  distributions   are
automatically  paid  in  full and  fractional  shares  of the  Fund,  unless the
shareholder requests that they be paid in  cash. Each purchase of shares of  the
Fund is made upon the condition that the Transfer Agent is thereby automatically
appointed  as agent of the  investor to receive all  dividends and capital gains
distributions on shares owned by the investor. Such dividends and  distributions
will  be paid, at the  net asset value per  share, in shares of  the Fund (or in
cash if the shareholder so requests) as of the close of business on the  monthly
payment  date, as stated in the Prospectus.  At any time an investor may request
the Transfer  Agent, in  writing, to  have subsequent  dividends and/or  capital
gains  distributions paid to  him or her  in cash rather  than shares. To assure
sufficient time to process  the change, such request  should be received by  the
Transfer  Agent at  least five business  days prior  to the payment  date of the
dividend or  the  record date  of  the distribution.  In  the case  of  recently
purchased  shares for which registration instructions  have not been received on
the payment or record date, cash payments will be made to DWR or other  selected
broker-dealer,  and will  be forwarded to  the shareholder, upon  the receipt of
proper instructions.
 
   
    TARGETED  DIVIDENDS-SM-.    In  states  where  it  is  legally  permissible,
shareholders  may also have all income dividends and capital gains distributions
automatically invested in shares of an open-end Dean Witter Fund other than Dean
Witter New York Tax-Free Income Fund. Such investment will be made as  described
above for automatic investment in shares of the Fund, at the net asset value per
share of the dividend or distribution of the selected Dean Witter Fund as of the
close  of business on the payment date and will begin to earn dividends, if any,
in the selected Dean Witter  Fund the next business  day. To participate in  the
Targeted  Dividends  program, shareholders  should  contact their  DWR  or other
selected broker-dealer account executive or the Transfer Agent. Shareholders  of
the  Fund  must be  shareholders of  the  Dean Witter  Fund targeted  to receive
investments from  dividends  at  the  time they  enter  the  Targeted  Dividends
program. Investors should review the prospectus of the targeted Dean Witter Fund
before entering the program.
    
 
   
    EASYINVEST-SM-.    Shareholders may  subscribe  to EasyInvest,  an automatic
purchase plan  which  provides  for  any  amount  from  $100  to  $5,000  to  be
transferred automatically from a checking or savings account, on a semi-monthly,
monthly  or quarterly basis, to  the Transfer Agent for  investment in shares of
the Fund. Shares purchased through EasyInvest will be added to the shareholder's
existing account at  the net asset  value calculated the  same business day  the
transfer  of  funds is  effected.  For further  information  or to  subscribe to
EasyInvest,  shareholders   should  contact   their   DWR  or   other   selected
broker-dealer account executive or the Transfer Agent.
    
 
    INVESTMENT  OF DIVIDENDS OR DISTRIBUTIONS RECEIVED IN CASH.  Any shareholder
who  receives  a  cash  payment   representing  a  dividend  or  capital   gains
distribution  may  invest  such dividend  or  distribution at  net  asset value,
without the imposition of a contingent deferred sales charge upon redemption, by
returning the check  or the proceeds  to the Transfer  Agent within thirty  days
after the payment date. If the shareholder returns the proceeds of a dividend or
distribution,  such funds must  be accompanied by  a signed statement indicating
that the proceeds  constitute a dividend  or distribution to  be invested.  Such
investment  will be made at the net  asset value per share next determined after
receipt of the check or proceeds by the Transfer Agent.
 
    DIRECT INVESTMENTS THROUGH TRANSFER AGENT.  As discussed in the  Prospectus,
a shareholder may make additional investments in Fund shares at any time through
the  Shareholder Investment Account by  sending a check in  any amount, not less
than $100, payable to Dean Witter New York Tax-Free Income Fund, directly to the
Fund's Transfer Agent.  Such amounts  will be applied  to the  purchase of  Fund
shares at the net asset value per share next computed after receipt of the check
or  purchase payment  by the  Transfer Agent.  The shares  so purchased  will be
credited to the investor's account.
 
                                       30
<PAGE>
    SYSTEMATIC WITHDRAWAL PLAN.   As discussed in  the Prospectus, a  systematic
withdrawal plan (the "Withdrawal Plan") is available for shareholders who own or
purchase  shares of the  Fund having a  minimum value of  $10,000 based upon the
then current  net asset  value.  The Withdrawal  Plan  provides for  monthly  or
quarterly (March, June, September and December) checks in any dollar amount, not
less  than  $25  or  in any  whole  percentage  of the  account  balance,  on an
annualized basis.  Any  applicable  contingent deferred  sales  charge  will  be
imposed  on  shares redeemed  under the  Withdrawal  Plan (see  "Redemptions and
Repurchases--Contingent Deferred Sales  Charge" in  the Prospectus).  Therefore,
any shareholder participating in the Withdrawal Plan will have sufficient shares
redeemed  from his or  her account so  that the proceeds  (net of any applicable
contingent deferred  sales charge)  to the  shareholder will  be the  designated
monthly or quarterly dollar amount.
 
    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 following business day) of the
relevant  month or quarter and normally a  check for the proceeds will be mailed
by the  Transfer Agent,  or amounts  credited to  a shareholder's  DWR or  other
selected  broker-dealer account,  within five  business days  after the  date of
redemption. The Withdrawal Plan may be terminated at any time by the Fund.
 
    Withdrawal Plan payments should  not be considered  as dividends, yields  or
income.  If periodic withdrawal plan payments continuously exceed net investment
income and  net capital  gains, the  shareholder's original  investment will  be
correspondingly reduced and ultimately exhausted.
 
    Each  withdrawal constitutes  a redemption  of shares  and any  gain or loss
realized must  be  recognized for  federal  income tax  purposes.  Although  the
shareholder  may  make  additional  investments  of  $2,500  or  more  under the
Withdrawal Plan,  withdrawals made  concurrently  with purchases  of  additional
shares  may  be  inadvisable because  of  the contingent  deferred  sales charge
applicable to the redemption of shares purchased during the preceding six  years
(see "Redemption and Repurchases--Contingent Deferred Sales Charge").
 
    Any  shareholder who wishes to have  payments under the Withdrawal Plan made
to a third party or sent to an address other than the one listed on the  account
must  send complete written instructions to the  Transfer Agent to enroll in the
Withdrawal Plan.  The  shareholder's  signature on  such  instructions  must  be
guaranteed   by  an  eligible   guarantor  acceptable  to   the  Transfer  Agent
(shareholders should  contact  the Transfer  Agent  for a  determination  as  to
whether  a particular institution is such  an eligible guarantor). A shareholder
may, at any time, change the amount and interval of withdrawal payments  through
his  or her DWR or other selected  broker-dealer 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
"Redemptions and Repurchases" in the Prospectus) at any time.
 
EXCHANGE PRIVILEGE
 
    As discussed in the Prospectus, the Fund makes available to its shareholders
an Exchange Privilege whereby shareholders of the Fund may exchange their shares
for  shares of  other Dean  Witter Funds sold  with a  contingent deferred sales
charge ("CDSC funds"), and  for shares of Dean  Witter Short-Term U.S.  Treasury
Trust,  Dean Witter  Limited Term Municipal  Trust, Dean  Witter Short-Term Bond
Fund, Dean Witter Balanced Income Fund,  Dean Witter Balanced Growth Fund,  Dean
Witter  Intermediate Term U.S. Treasury Trust and  for shares of any Dean Witter
money market funds (the foregoing eleven non-FESC or CDSC funds are  hereinafter
referred to for purposes of this section as the "Exchange Funds"). Exchanges may
be  made after the shares  of the Fund acquired by  purchase (not by exchange or
dividend reinvestment) have been  held for 30 days.  There is no waiting  period
for exchanges of shares
 
                                       31
<PAGE>
acquired  by exchange or dividend reinvestment.  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.)
 
   
    As described  below, and  in  the Prospectus  under the  captions  "Exchange
Privilege"  and "Contingent Deferred Sales  Charge," a contingent deferred sales
charge ("CDSC")  may be  imposed upon  a redemption,  depending on  a number  of
factors,  including the number of years from the time of purchase until the time
of redemption or  exchange ("holding period").  When shares of  the Fund or  any
other  CDSC fund are exchanged for shares of the Exchange Funds, the exchange is
executed at no charge to the shareholder, without the imposition of the 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  fund
shares  were acquired), 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 exchanged into  the
Exchange  Funds 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  the Exchange Funds 12b-1  distribution
fees  incurred on  or after  that date which  are attributable  to those shares.
Shareholders acquiring shares of  the Exchange Funds  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 the Exchange Funds 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.
    
 
    In addition, shares of the  Fund may be acquired  in exchange for shares  of
Dean  Witter Funds sold  with a front-end sales  charge ("front-end sales charge
funds"), but shares  of the  Fund, however acquired,  may not  be exchanged  for
shares  of  front-end sales  charge funds.  Shares  of a  CDSC fund  acquired in
exchange for shares of a front-end sales charge fund (or in exchange for  shares
of  other Dean Witter  Funds for which  shares of a  front-end sales charge 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 the Exchange Funds, 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 prior to the  exchange, (ii) originally acquired through  reinvestment
of  dividends  or distributions  and (iii)  acquired in  exchange for  shares of
front-end sales charge funds, or for shares of other Dean Witter Funds for which
shares of front-end  sales charge  funds have  been exchanged  (all such  shares
called  "Free Shares"), will be exchanged  first. Shares of Dean Witter American
Value Fund (formerly Dean Witter Industry-Valued Securities Inc.) 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 the Exchange
Funds will be considered Free Shares. If the exchanged amount exceeds the  value
of such Free Shares, an
 
                                       32
<PAGE>
   
exchange  is made, on  a block-by-block basis,  of non-Free Shares  held for the
longest period of time (except that if shares held for identical periods of time
but subject to different CDSC schedules are held in the same Exchange  Privilege
account,  the shares of that block that are subject to a lower CDSC rate will be
exchanged prior to the shares  of that block that are  subject to a higher  CDSC
rate).  Shares  equal  to  any  appreciation in  the  value  of  non-Free Shares
exchanged will  be  treated as  Free  Shares, and  the  amount of  the  purchase
payments for the non-Free Shares of the fund exchanged into will be equal to the
lesser  of (a) the purchase payments for, or (b) the current net asset value of,
the exchanged non-Free  Shares. If  an exchange  between funds  would result  in
exchange  of only  part of  a particular block  of non-Free  Shares, then shares
equal to any appreciation  in the value of  the block (up to  the amount of  the
exchange)  will be treated as Free Shares  and exchanged first, and the purchase
payment for  that  block will  be  allocated on  a  pro-rata basis  between  the
non-Free  Shares of  that block  to be  retained and  the non-Free  Shares to be
exchanged. The  prorated amount  of such  purchase payment  attributable to  the
retained  non-Free Shares will  remain as the purchase  payment for such shares,
and the amount  of purchase payment  for the exchanged  non-Free Shares will  be
equal  to the lesser of (a) the prorated  amount of the purchase payment for, or
(b) the current net asset value of, those exchanged non-Free Shares. Based  upon
the  procedures  described  in  the  Prospectus  under  the  caption "Contingent
Deferred Sales Charge," any  applicable CDSC will be  imposed upon the  ultimate
redemption  of shares of any  fund, regardless of the  number of exchanges since
those shares were originally purchased.
    
 
   
    With respect to  the redemption  or repurchase of  shares of  the Fund,  the
application  of proceeds to the purchase of new  shares in the Fund or any other
of the  funds and  the general  administration of  the Exchange  Privilege,  the
Transfer  Agent  acts as  agent for  the Distributor  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, the Distributor  or any  selected
broker-dealer.  The Distributor  and any selected  broker-dealer have authorized
and appointed the Transfer Agent  to act as their  agent in connection with  the
application  of proceeds  of any  redemption of Fund  shares to  the purchase of
shares of  any  other  fund  and the  general  administration  of  the  Exchange
Privilege.  No commission or  discounts will be  paid to the  Distributor or any
selected broker-dealer for any transactions pursuant to this Exchange Privilege.
    
 
   
    Exchanges are subject to  the minimum investment  requirement and any  other
conditions  imposed by each fund. (The  minimum initial investment is $5,000 for
Dean Witter Liquid  Asset Fund Inc.,  Dean Witter Tax-Free  Daily Income  Trust,
Dean  Witter New  York Municipal  Money Market  Fund 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
is $10,000 for Dean  Witter Short-Term U.S. Treasury  Trust, although that  fund
may,  at  its discretion,  accept initial  purchases  of as  low as  $5,000. The
minimum initial investment  is $5,000 for  Dean Witter Special  Value Fund.  The
minimum  initial  investment  for all  other  Dean  Witter Funds  for  which the
Exchange Privilege is available  is $1,000.) Upon exchange  into a money  market
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  the Fund and/or any of  the Dean Witter Funds for  which
shares  of the Fund have been exchanged, upon  such notice as may be required by
applicable regulatory agencies  (presently sixty days  prior written notice  for
termination or material revision), provided that six months prior written notice
of termination will be given to the shareholders who hold shares of the Exchange
Funds pursuant to this Exchange Privilege and provided further that the Exchange
Privilege  may be terminated  or materially revised without  notice 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
 
                                       33
<PAGE>
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, policies and
restrictions.
 
   
    For further  information  regarding  the  Exchange  Privilege,  shareholders
should  contact their DWR  or other selected  broker-dealer account executive or
the Transfer Agent.
    
 
REDEMPTIONS AND REPURCHASES
- --------------------------------------------------------------------------------
 
    REDEMPTION.  As stated in the Prospectus, shares of the Fund can be redeemed
for cash at any time at the net asset value per share next determined;  however,
such  redemption  proceeds  may  be  reduced by  the  amount  of  any applicable
contingent  deferred  sales  charge  (see  below).  If  shares  are  held  in  a
shareholder's  account  without  a  share  certificate,  a  written  request for
redemption to the Fund's Transfer Agent at P.O. Box 983, Jersey City, New Jersey
07303 is required. If certificates are  held by the shareholder, the shares  may
be  redeemed  by  surrendering  the  certificates  with  a  written  request for
redemption. The  share certificate,  or  an accompanying  stock power,  and  the
request  for  redemption,  must be  signed  by the  shareholder  or shareholders
exactly as the shares  are registered. Each request  for redemption, whether  or
not  accompanied by  a share  certificate, must be  sent to  the Fund's Transfer
Agent, which will redeem the shares at their net asset value next computed  (see
"Purchase  of Fund Shares" in the Prospectus) after it receives the request, and
certificate, if any, in good order.  Any redemption request received after  such
computation  will be redeemed at  the next determined net  asset value. The term
"good order"  means  that  the  share  certificate,  if  any,  and  request  for
redemption are properly signed, accompanied by any documentation required by the
Transfer  Agent, and bear signature guarantees when  required by the Fund or the
Transfer Agent. If redemption is requested by a corporation, partnership,  trust
or  fiduciary, the Transfer Agent may require that written evidence of authority
acceptable to the Transfer Agent be submitted before such request is accepted.
 
   
    Whether certificates are  held by the  shareholder or shares  are held in  a
shareholder's  account, if the proceeds are to  be paid to any person other than
the record owner, or if the proceeds are to be paid to a corporation (other than
the Distributor or a selected broker-dealer for the account of the shareholder),
partnership, trust or fiduciary, or sent to the shareholder at an address  other
than  the  registered  address, signatures  must  be guaranteed  by  an eligible
guarantor acceptable  to the  Transfer Agent  (shareholders should  contact  the
Transfer  Agent for  a determination as  to whether a  particular institution is
such an eligible guarantor). A  stock power may be  obtained from any dealer  or
commercial  bank. The Fund may change  the signature guarantee requirements from
time to time upon notice to shareholders, which may be by means of a  supplement
to the prospectus or a revised prospectus.
    
 
    CONTINGENT DEFERRED SALES CHARGE.  As stated in the Prospectus, a contingent
deferred  sales charge ("CDSC") will be imposed on any redemption by an investor
if after such redemption the current value of the investor's shares of the  Fund
is  less  than the  dollar amount  of all  payments by  the shareholder  for the
purchase of Fund shares during the preceding six years. However, no CDSC will be
imposed to the extent that the net  asset value of the shares redeemed does  not
exceed:  (a) the current net asset value of shares purchased more than six years
prior to  the  redemption,  plus (b)  the  current  net asset  value  of  shares
purchased  through reinvestment  of dividends  or distributions  of the  Fund or
another Dean Witter Fund (see "Shareholder Services--Targeted Dividends"),  plus
(c) the current net asset value of shares acquired in exchange for (i) shares of
Dean  Witter front-end sales charge  funds, or (ii) shares  of other Dean Witter
Funds for which shares of front-end sales charge funds have been exchanged  (see
"Shareholder Services--Exchange Privilege"), plus (d) increases in the net asset
value  of  the investor's  shares above  the  total amount  of payments  for the
purchase of Fund shares made  during the preceding six  years. The CDSC will  be
paid to the Distributor.
 
                                       34
<PAGE>
    In  determining the applicability of the CDSC to each redemption, the amount
which represents an  increase in the  net asset value  of the investor's  shares
above  the amount of  the total payments  for the purchase  of shares within the
past six  years will  be redeemed  first.  In the  event the  redemption  amount
exceeds  such increase in value, the next portion of the amount redeemed will be
the amount  which  represents the  net  asset  value of  the  investor's  shares
purchased  more than six  years prior to the  redemption and/or shares purchased
through reinvestment of  dividends or  distributions and/or  shares acquired  in
exchange for shares of Dean Witter front-end sales charge funds or for shares of
other  Dean Witter funds for  which shares of front-end  sales charge funds have
been exchanged. A portion of the  amount redeemed which exceeds an amount  which
represents  both such increase in  value and the value  of shares purchased more
than  six  years  prior  to  the  redemption  and/or  shares  purchased  through
reinvestment  of  dividends  or  distributions  and/or  shares  acquired  in the
above-described exchanges will be subject to a CDSC.
 
    The amount of the CDSC, if any,  will vary depending on the number of  years
from  the time  of payment  for the purchase  of Fund  shares until  the time of
redemption of such shares. For purposes of determining the number of years  from
the  time of any payment for the purchase  of shares, all payments made during a
month will be aggregated  and deemed to have  been made on the  last day of  the
month. The following table sets forth the rates of the CDSC:

</TABLE>
 
    In determining the rate of the CDSC, it will be assumed that a redemption is
made  of shares held by  the investor for the longest  period of time within the
applicable six-year period. This will result  in any such CDSC being imposed  at
the   lowest  possible  rate.  Accordingly,  shareholders  may  redeem,  without
incurring any CDSC,  amounts equal to  any net  increase in the  value of  their
shares  above the  amount of  their purchase payments  made within  the past six
years and amounts equal to the current  value of shares purchased more than  six
years  prior  to the  redemption and  shares  purchased through  reinvestment of
dividends or distributions  or acquired in  exchange for shares  of Dean  Witter
front-end sales charge funds, or for shares of other Dean Witter Funds for which
shares  of front-end sales  charge funds have  been exchanged. The  CDSC will be
imposed, in accordance with the table shown above, on any redemptions within six
years of purchase which are in excess of these amounts and which redemptions are
not (a)  requested  within  one  year  of  death  or  initial  determination  of
disability   of  a  shareholder,  or  (b)   made  pursuant  to  certain  taxable
distributions from retirement plans or retirement accounts, as described in  the
Prospectus.
 
    PAYMENT FOR SHARES REDEEMED OR REPURCHASED.  As discussed in the Prospectus,
payment  for shares presented for repurchase or redemption will be made by check
within seven days after receipt by the Transfer Agent of the certificate  and/or
written  request  in good  order. The  term  "good order"  means that  the share
certificate,  if  any,  and  request   for  redemption,  are  properly   signed,
accompanied  by  any  documentation required  by  the Transfer  Agent,  and bear
signature guarantees  when required  by the  Fund or  the Transfer  Agent.  Such
payment  may be postponed or the right of redemption suspended 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, or (d) during any other period
when the Securities and Exchange Commission  by order so permits; provided  that
applicable rules and
 
                                       35
<PAGE>
regulations of the Securities and Exchange Commission shall govern as to whether
the conditions prescribed in (b) or (c) exist. If the shares to be redeemed have
recently  been  purchased  by check  (including  a certified  or  bank cashier's
check), payment  of redemption  proceeds may  be delayed  for the  minimum  time
needed  to verify that the check used  for investment has been honored (not more
than fifteen days from the  time of investment of the  proceeds of the check  by
the  Transfer  Agent).  Shareholders  maintaining margin  accounts  with  DWR or
another  selected  broker-dealer  are  referred  to  their  account   executives
regarding restrictions on redemption of shares of the Fund pledged in the margin
account.
 
    TRANSFERS  OF SHARES.  In the event a shareholder requests a transfer of any
shares to a  new registration,  such shares  will be  transferred without  sales
charge  at the time of  transfer. With regard to the  status of shares which are
either subject to the  contingent deferred sales charge  or free of such  charge
(and  with regard to the  length of time shares subject  to the charge have been
held), any transfer involving less than all of the shares in an account will  be
made on a pro-rata basis (that is, by transferring shares in the same proportion
that  the transferred shares bear to the total shares in the account immediately
prior to the transfer).  The transferred shares will  continue to be subject  to
any  applicable contingent  deferred sales  charge as  if they  had not  been so
transferred.
 
    REINSTATEMENT PRIVILEGE.  As discussed in the Prospectus, a shareholder  who
has  had  his or  her  shares redeemed  or  repurchased and  has  not previously
exercised this  reinstatement  privilege  may,  within  thirty  days  after  the
redemption  or repurchase, reinstate any portion or  all of the proceeds of such
redemption or repurchase  in shares  of the  Fund at  the net  asset value  next
determined  after  a  reinstatement  request,  together  with  the  proceeds, is
received by the Transfer Agent.
 
    Exercise of the reinstatement privilege  will not affect the federal  income
tax  treatment of any gain  or loss realized upon  the redemption or repurchase,
except that if the redemption or repurchase resulted in a loss and reinstatement
is made in shares of the Fund, some or all of the loss, depending on the  amount
reinstated,  will not be allowed as a  deduction for federal income tax purposes
but will  be applied  to  adjust the  cost basis  of  the shares  acquired  upon
reinstatement.
 
DIVIDENDS, DISTRIBUTIONS AND TAXES
- --------------------------------------------------------------------------------
 
    As  stated in the Prospectus, the Fund  intends to distribute all of its net
investment income and all of its net short-term capital gains, if any, and  will
determine whether to retain all or part of any net long-term capital gains.
 
    As  discussed in the Prospectus, the Fund may invest a portion of its assets
in certain "private activity bonds" issued after August 7, 1986. As a result,  a
portion  of the exempt-interest dividends paid by the Fund may be an item of tax
preference to  shareholders  subject to  the  federal alternative  minimum  tax.
Certain  corporations which are subject to  the alternative minimum tax may also
have to  include a  portion of  exempt-interest dividends  in calculating  their
alternative  minimum taxable  income in  situations where  the "adjusted current
earnings" of the corporation exceeds its alternative minimum taxable income.
 
    Each shareholder will be  sent at least  a quarterly summary  of his or  her
account,  including  information as  to reinvested  dividends and  capital gains
distributions. 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.
 
    In  computing  interest  income, the  Fund  will amortize  any  premiums and
original issue discounts on securities  owned. Capital gains or losses  realized
upon sale or maturity of such securities will be based on their amortized cost.
 
    Gains  or losses on  the sales of  securities by the  Fund will be long-term
capital gains or losses if  the securities have been held  by the Fund for  more
than  twelve months. Gains or  losses on the sale  of securities held for twelve
months or less will be short-term capital  gains or losses. Gains and losses  on
 
                                       36
<PAGE>
the  sale,  expiration  or  other  termination  of  options  on  securities will
generally be treated as gains and  losses from the sale of securities.  Pursuant
to  present federal income tax  laws, futures contracts held  by the Fund at the
end of each  fiscal year will  be required to  be "marked to  market", that  is,
treated  as having  been sold  at their  fair market  value at  such date. Sixty
percent of any gain or loss recognized on these deemed sales will be treated  as
long-term  capital gain or loss, and the remainder will be treated as short-term
capital gain or loss. Gains or losses from options on futures and listed options
on debt  instruments will  similarily be  treated as  part short-term  and  part
long-term  capital gains or losses, unless such gains or losses were incurred as
part of a securities "straddle," in which case the appropriate straddle rules of
the Internal Revenue Code (the "Code") would apply.
 
    Because the Fund intends to distribute all of its net investment income  and
capital  gains to shareholders and otherwise  continue to qualify as a regulated
investment company under Subchapter  M of the Internal  Revenue Code, it is  not
expected  that  the  Fund  will  be required  to  pay  any  federal  income tax.
Shareholders will normally have to pay federal income taxes, and any  applicable
state and/or local income taxes, on the dividends and distributions they receive
from  the Fund. Such  dividends and distributions,  to the extent  that they are
derived from net investment income or  short-term capital gains, are taxable  to
the  shareholder  as  ordinary  income  regardless  of  whether  the shareholder
receives such payments in additional shares  or in cash. Any dividends  declared
in  the last quarter of  any calendar year which are  paid in the following year
prior to February  1 will be  deemed received  by the shareholder  in the  prior
calendar year.
 
    With  respect  to the  Fund's  investments in  zero  coupon bonds,  the Fund
accrues income prior to any actual cash  payments by their issuers. In order  to
continue  to comply  with Subchapter  M of  the Code  and remain  able to forego
payment of Federal income  tax on its  income and capital  gains, the Fund  must
distribute  all of its net investment income, including income accrued from zero
coupon bonds.  As such,  the Fund  may be  required to  dispose of  some of  its
portfolio  securities under  disadvantageous circumstances to  generate the cash
required for distribution.
 
    One of the requirements for regulated  investment company status is that  at
least 90% of a Fund's gross income be derived from dividends, interest and gains
from  the  sale  or other  disposition  of securities.  Another  requirement for
regulated investment company status  is that less than  30% of the Fund's  gross
income  can be derived from,  among other sources, gains  from the sale or other
disposition of securities held less than three months. Accordingly, the Fund may
be restricted in the writing of options  on securities held for less than  three
months, in the writing of options which expire in less than three months, and in
effecting  closing transactions with  respect to call or  put options which have
been written or purchased less than three months prior to such transactions. The
Fund may also be restricted in  its ability to engage in transactions  involving
futures contracts.
 
    Under the Revenue Reconciliation Act of 1993, all or a portion of the Fund's
gain from the sale or redemption of tax-exempt obligations purchased at a market
discount  after April 30,  1993 will be  treated as ordinary  income rather than
capital gain. This  rule may increase  the amount of  ordinary income  dividends
received by shareholders.
 
    As  discussed in the Prospectus, the Fund  intends to continue 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  dividend distributions 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.
 
    Within  sixty 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  the percentage,  if  any,  of the
exempt-interest dividends which constitutes  an item of  tax preference, and  to
what  extent the taxable  portion is long-term  capital gain, short-term capital
gain or ordinary income. These percentages should
 
                                       37
<PAGE>
be applied uniformly to all monthly distributions made during the fiscal year to
determine the proportion of  dividends that is  tax-exempt. The percentages  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  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 gains, regardless of
how long the shareholder  has held Fund shares  and whether the distribution  is
received in additional shares or in cash. Since the Fund's income is expected to
be  derived entirely from interest rather  than dividends, none of such dividend
distributions  will  be  eligible  for  the  70%  dividends  received  deduction
generally  available to corporations. Net  long-term capital gains distributions
are not eligible for the dividends received deduction.
 
    Any loss on the sale  or exchange of shares of  the Fund which are held  for
six  months  or  less  is  disallowed  to  the  extent  of  the  amount  of  any
exempt-interest dividends paid with respect to such shares. Treasury Regulations
may provide for a  reduction in such required  holding period. If a  shareholder
receives  a distribution that is taxed as  long-term capital gain on shares held
for six months  or less  and sells  those shares  at a  loss, the  loss will  be
treated  as  a  long-term  capital  loss to  the  extent  of  the  capital gains
distribution.
 
    Interest on indebtedness incurred or continued by a shareholder to  purchase
or  carry  shares of  the  Fund is  not deductible  to  the extent  allocable to
exempt-interest dividends  of the  Fund  (which allocation  does not  take  into
account  capital gain dividends  of the Fund).  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
a 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. It can be expected that 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 such
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.
 
    The Fund is organized as a Massachusetts business trust. Under current  law,
so  long as it qualifies as a  "regulated investment company" under the Internal
Revenue Code, the Fund itself is not  liable for any income or franchise tax  in
The Commonwealth of Massachusetts.
 
    Any  dividend or capital  gains distribution received  by a shareholder from
any investment company will have the effect  of reducing the net asset value  of
the  shareholder's stock  in that fund  by the  exact amount of  the dividend or
capital gains distribution.  Furthermore, capital gains  distributions are,  and
some  portion of the dividends  may be, subject to income  tax. If the net asset
value of the shares should be reduced below a shareholder's cost as a result  of
the payment of taxable dividends or the distribution
 
                                       38
<PAGE>
of  realized long-term capital  gains, such payment  or distribution, in effect,
would be  a  return  of  capital but  nonetheless  taxable  at  ordinary  rates.
Therefore,  an investor should consider the  tax implications of purchasing Fund
shares immediately prior to a distribution record date.
 
PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------
 
   
    As discussed in the  Prospectus, from time  to time the  Fund may quote  its
"yield"  and/or its "total return" in advertisements and sales literature. Yield
is calculated for any  30-day period as follows:  the amount of interest  income
for  each  security in  the Fund's  portfolio is  determined in  accordance with
regulatory requirements;  the total  for the  entire portfolio  constitutes  the
Fund's  gross  income for  the period.  Expenses accrued  during the  period are
subtracted to arrive at "net investment income". The resulting amount is divided
by the product of the net  asset value per share on  the last day of the  period
multiplied  by the average  number of Fund shares  outstanding during the period
that were entitled to  dividends. This amount  is added to 1  and raised to  the
sixth  power.  1  is then  subtracted  from  the result  and  the  difference is
multiplied by 2 to arrive at the  annualized yield. For the 30-day period  ended
December  31,  1996,  the  Fund's  yield,  calculated  pursuant  to  the formula
described above was 4.15%.
    
 
   
    The Fund may also quote a "tax-equivalent yield" determined by dividing  the
tax-exempt portion of the quoted yield by 1 minus the stated income tax rate and
adding the result to the portion of the yield that is not tax-exempt. The Fund's
tax-equivalent  yield, based upon a combined Federal and New York State personal
income tax bracket of 44.70% (the highest current individual marginal tax rate),
for the 30-day period ending December 31,  1996, was 7.50% based upon the  yield
quoted above.
    
 
    The  Fund's "average annual total return" represents an annualization of the
Fund's total return  over a  particular period and  is computed  by finding  the
annual  percentage rate which  will result in  the ending redeemable  value of a
hypothetical $1,000 investment made at the beginning of a one, five or ten  year
period,  or  for  the  period  from  the  date  of  commencement  of  the Fund's
operations, if shorter than any of the foregoing. The ending redeemable value is
reduced by any contingent deferred sales charge  at the end of the one, five  or
ten  year or other  period. For the  purpose of this  calculation, it is assumed
that all dividends and distributions  are reinvested. The formula for  computing
the  average annual total return involves  a percentage obtained by dividing the
ending redeemable value by the amount  of the initial investment, taking a  root
of  the quotient  (where the root  is equivalent to  the number of  years in the
period), and subtracting 1 from the result.
 
   
    The average annual total returns of the Fund for the year ended December 31,
1996, the  five years  ended  December 31,  1996 and  for  the ten  years  ended
December 31, 1996, were -2.08%, 5.76% and 6.50%, respectively.
    
 
   
    In  addition to the foregoing, the Fund  may advertise its total return over
different periods of time by means of aggregate, average, year-by-year or  other
types  of total  return figures.  Such calculations may  or may  not reflect the
deduction of the  contingent deferred  sales charge which,  if reflected,  would
reduce  the performance quoted. For example,  the average annual total return of
the Fund may be calculated in the manner described above, but without  deduction
for  any applicable contingent deferred sales charge. Based on this calculation,
the average annual total  returns of the  Fund for the  year ended December  31,
1996,  the  five years  ended  December 31,  1996 and  for  the ten  years ended
December 31, 1996, were 2.82%, 6.08% and 6.50%, respectively.
    
 
   
    In addition, the Fund may compute  its aggregate total return for  specified
periods  by determining the  aggregate percentage rate which  will result in the
ending value of a  hypothetical $1,000 investment made  at the beginning of  the
period.  For the purpose of  this calculation, it is  assumed that all dividends
and distributions  are reinvested.  The formula  for computing  aggregate  total
return  involves a percentage obtained by dividing the ending value (without the
reduction for  any  contingent deferred  sales  charge) by  the  initial  $1,000
investment   and  subtracting  1  from  the   result.  Based  on  the  foregoing
calculation, the Fund's total return for  the year ended December 31, 1996,  the
five  years ended December 31,  1996 and the ten  years ended December 31, 1996,
were 2.82%, 34.31% and 87.71%, respectively.
    
 
                                       39
<PAGE>
   
    The Fund  may  also advertise  the  growth of  hypothetical  investments  of
$10,000,  $50,000 and $100,000 in  shares of the Fund by  adding 1 to the Fund's
aggregate total  return  (expressed as  a  decimal and  without  reflecting  the
deduction  of the contingent deferred sales  charge) and multiplying by $10,000,
$50,000 and $100,000. Investments of $10,000,  $50,000 and $100,000 in the  Fund
since  inception  (April 25,  1985) would  have grown  to $24,517,  $122,585 and
$245,170, respectively at December 31, 1996.
    
 
    The Fund from time  to time may also  advertise its performance relative  to
certain performance rankings and indexes compiled by independent organizations.
 
SHARES OF THE FUND
- --------------------------------------------------------------------------------
 
    As discussed in the Prospectus, the shareholders of the Fund are entitled to
a  full vote for each  full share held. All of  the Trustees, except for Messrs.
Bozic, Purcell and Schroeder have been elected by the shareholders of the  Fund,
most  recently at a  Special Meeting of  Shareholders held on  January 12, 1993.
Messrs. Bozic, Purcell and Schroeder were  elected by the other Trustees of  the
Fund  on April  8, 1994.  The Trustees  themselves have  the power  to alter the
number and  the terms  of office  of  the Trustees,  and they  may at  any  time
lengthen  their own terms or make their  terms of unlimited duration and appoint
their own successors, provided that always  at least a majority of the  Trustees
has  been elected by  the shareholders of the  Fund. Under certain circumstances
the Trustees may  be removed by  action of the  Trustees. The shareholders  also
have  the right under  certain circumstances to remove  the Trustees. The voting
rights of  shareholders are  not cumulative,  so that  holders of  more than  50
percent  of the  shares voting  can, if  they choose,  elect all  Trustees being
selected, while the holders of the remaining shares would be unable to elect any
Trustees.
 
   
    The Declaration of Trust permits the  Trustees to authorize the creation  of
additional  series  of  shares  (the  proceeds of  which  would  be  invested in
separate, independently  managed portfolios)  and additional  classes of  shares
within  any  series (which  would be  used  to distinguish  among the  rights of
different categories of shareholders, as might be required by future regulations
or other unforeseen circumstances). The  Trustees have not presently  authorized
any such additional series or classes of shares.
    
 
    The Declaration of Trust further provides that no Trustee, officer, employee
or  agent of  the Fund is  liable to the  Fund or  to a shareholder,  nor is any
Trustee, officer, employee or  agent liable to any  third persons in  connection
with the affairs of the Fund, except as such liability may arise from his/her or
its  own bad faith, willful misfeasance, gross negligence, or reckless disregard
of his/her or its  duties. It also  provides that all  third persons shall  look
solely  to the Fund's property for  satisfaction of claims arising in connection
with the affairs  of the Fund.  With the exceptions  stated, the Declaration  of
Trust  provides that  a Trustee,  officer, employee or  agent is  entitled to be
indemnified against all liability in connection with the affairs of the Fund.
 
    The Fund is authorized to issue an unlimited number of shares of  beneficial
interest.  The Fund shall be of unlimited  duration subject to the provisions in
the Declaration of Trust concerning termination by action of the shareholders.

REPORT OF INDEPENDENT ACCOUNTANTS
 
TO THE SHAREHOLDERS AND TRUSTEES
OF DEAN WITTER NEW YORK TAX-FREE INCOME FUND
 
   
In our opinion, the accompanying statement of assets and liabilities, including
the portfolio of investments and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Dean Witter New York Tax-Free
Income Fund (the "Fund") at December 31, 1996, the results of its operations for
the year then ended, the changes in its net assets for each of the two years in
the period then ended and the financial highlights for each of the ten years in
the period then ended, in conformity with generally accepted accounting
principles. These financial statements and financial highlights (hereafter
referred to as "financial statements") are the responsibility of the Fund's
management; our responsibility is to express an opinion on these financial
statements based on our audits. We conducted our audits of these financial
statements in accordance with generally accepted auditing standards which
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statements presentation. We believe that our audits, which included
confirmation of securities at December 31, 1996 by correspondence with the
custodian, provide a reasonable basis for the opinion expressed above.

NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 1996
    
 
   
1. ORGANIZATION AND ACCOUNTING POLICIES
    
 
   
Dean Witter New York Tax-Free Income Fund (the "Fund") is registered under the
Investment Company Act of 1940, as amended (the "Act"), as a diversified,
open-end management investment company. The Fund's investment objective is to
provide a high level of current income which is exempt from federal, New York
State and New York City income tax, consistent with the preservation of capital.
The Fund was organized as a Massachusetts business trust on January 17, 1985 and
commenced operations on April 25, 1985.
    
 
   
The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts and disclosures. Actual results could differ from
those estimates.
    
 
   
The following is a summary of significant accounting policies:
    
 
   
A. VALUATION OF INVESTMENTS -- Portfolio securities are valued for the Fund by
an outside independent pricing service approved by the Trustees. The pricing
service has informed the Fund that in valuing the Fund's portfolio securities,
it uses both a computerized matrix of tax-exempt securities and evaluations by
its staff, in each case based on information concerning market transactions and
quotations from dealers which reflect the bid side of the market each day. The
Fund's portfolio securities are thus valued by reference to a combination of
transactions and quotations for the same or other securities believed to be
comparable in quality, coupon, maturity, type of issue, call provisions, trading
characteristics and other features deemed to be relevant. Short-term debt
securities having a maturity date of more than sixty days at time of purchase
are valued on a mark-to-market basis until sixty days prior to maturity and
thereafter at amortized cost based on their value on the 61st day. Short-term
debt securities having a maturity date of sixty days or less at the time of
purchase are valued at amortized cost.
    
 
   
B. ACCOUNTING FOR INVESTMENTS -- Security transactions are accounted for on the
trade date (date the order to buy or sell is executed). Realized gains and
losses on security transactions are determined by the identified cost method.
The Fund amortizes premiums and accretes discounts over the life of the
respective securities. Interest income is accrued daily.
    
 
   
C. FEDERAL INCOME TAX STATUS -- It is the Fund's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute all of its taxable and nontaxable income to its
shareholders. Accordingly, no federal income tax provision is required.

NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 1996 , CONTINUED
    
 
   
D. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- The Fund records dividends and
distributions to its shareholders on the record date. The amount of dividends
and distributions from net investment income and net realized capital gains are
determined in accordance with federal income tax regulations which may differ
from generally accepted accounting principles. These "book/tax" differences are
either considered temporary or permanent in nature. To the extent these
differences are permanent in nature, such amounts are reclassified within the
capital accounts based on their federal tax-basis treatment; temporary
differences do not require reclassification. Dividends and distributions which
exceed net investment income and net realized capital gains for financial
reporting purposes but not for tax purposes are reported as dividends in excess
of net investment income or distributions in excess of net realized capital
gains. To the extent they exceed net investment income and net realized capital
gains for tax purposes, they are reported as distributions of paid-in-capital.
    
 
   
2. INVESTMENT MANAGEMENT AGREEMENT
    
 
   
Pursuant to an Investment Management Agreement with Dean Witter InterCapital
Inc. (the "Investment Manager"), the Fund pays the Investment Manager a
management fee, accrued daily and payable monthly, by applying the following
annual rates to the Fund's net assets determined as of the close of each
business day: 0.55% to the portion of daily net assets not exceeding $500
million and 0.525% to the portion of daily net assets exceeding $500 million.
    
 
   
Under the terms of the Agreement, in addition to managing the Fund's
investments, the Investment Manager maintains certain of the Fund's books and
records and furnishes, at its own expense, office space, facilities, equipment,
clerical, bookkeeping and certain legal services and pays the salaries of all
personnel, including officers of the Fund who are employees of the Investment
Manager. The Investment Manager also bears the cost of telephone services, heat,
light, power and other utilities provided to the Fund.
    
 
   
3. PLAN OF DISTRIBUTION
    
 
   
Shares of the Fund are distributed by Dean Witter Distributors Inc. (the
"Distributor"), an affiliate of the Investment Manager. The Fund has adopted a
Plan of Distribution (the "Plan") pursuant to Rule 12b-1 under the Act pursuant
to which the Fund pays the Distributor compensation, accrued daily and payable
monthly, at an annual rate of 0.75% of the lesser of: (a) the average daily
aggregate gross sales of the Fund's shares since the Fund's inception (not
including reinvestment of dividend or capital gain distributions) less the
average daily aggregate net asset value of the Fund's shares redeemed since the
Fund's inception upon which a contingent deferred sales charge has been

NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 1996 , CONTINUED
    
 
   
imposed or upon which such charge has been waived; or (b) the Fund's average
daily net assets. Amounts paid under the Plan are paid to the Distributor to
compensate it for the services provided and the expenses borne by it and others
in the distribution of the Fund's shares, including the payment of commissions
for sales of the Fund's shares and incentive compensation to, and expenses of,
account executives of Dean Witter Reynolds Inc., an affiliate of the Investment
Manager and Distributor, and other employees and selected broker-dealers, who
engage in or support distribution of the Fund's shares or who service
shareholder accounts, including overhead and telephone expenses, printing and
distribution of prospectuses and reports used in connection with the offering of
the Fund's shares to other than current shareholders and preparation, printing
and distribution of sales literature and advertising materials. In addition, the
Distributor may be compensated under the Plan for its opportunity costs in
advancing such amounts, which compensation would be in the form of a carrying
charge on any unreimbursed expenses by the Distributor.
    
 
   
Provided that the Plan continues in effect, any cumulative expenses incurred but
not yet recovered may be recovered through future distribution fees from the
Fund and contingent deferred sales charges from the Fund's shareholders.
    
 
   
Although there is no legal obligation for the Fund to pay expenses incurred in
excess of payments made to the Distributor under the Plan and the proceeds of
contingent deferred sales charges paid by investors upon redemption of shares,
if for any reason the Plan is terminated, the Trustees will consider at that
time the manner in which to treat such expenses. The Distributor has advised the

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

<PAGE>
                             MUNICIPAL NOTE RATINGS
 
    Moody's ratings for state and municipal note and other short-term loans  are
designated  Moody's Investment Grade (MIG). MIG 1 denotes best quality and means
there is  present  strong  protection  from  established  cash  flows,  superior
liquidity   support  or  demonstrated  broad-based  access  to  the  market  for
refinancing. MIG 2 denotes high quality and means that margins of protection are
ample although not as  large as in  MIG 1. MIG 3  denotes favorable quality  and
means  that  all security  elements are  accounted for  but that  the undeniable
strength of the  previous grades, MIG  1 and MIG  2, is lacking.  MIG 4  denotes
adequate  quality and means that the protection commonly regarded as required of
an investment security is present and that while the notes are not distinctly or
predominantly speculative, there is specific risk.
 
                        VARIABLE RATE DEMAND OBLIGATIONS
 
    A short-term rating, in addition to the Bond or MIG ratings, designated VMIG
may also be assigned to an issue having a demand feature. The assignment of  the
VMIG symbol reflects such characteristics as payment upon periodic demand rather
than  fixed maturity dates  and payment relying on  external liquidity. The VMIG
rating criteria are identical to the MIG criteria discussed above.
 
                            COMMERCIAL PAPER RATINGS
 
    Moody's Commercial  Paper  ratings are  opinions  of the  ability  to  repay
punctually  promissory obligations not having an  original maturity in excess of
nine months.  These ratings  apply  to Municipal  Commercial  Paper as  well  as
taxable  Commercial Paper. Moody's employs the following three designations, all
judged to be investment  grade, to indicate the  relative repayment capacity  of
rated issuers: Prime-1, Prime-2, Prime-3.
 
    Issuers  rated Prime-1 have a superior  capacity for repayment of short-term
promissory obligations.  Issuers  rated  Prime-2  have  a  strong  capacity  for
repayment  of short-term promissory obligations;  and Issuers rated Prime-3 have
an acceptable  capacity  for  repayment of  short-term  promissory  obligations.
Issuers rated Not Prime do not fall within any of the Prime rating categories.
 
STANDARD & POOR'S CORPORATION ("STANDARD & POOR'S")
 
                             MUNICIPAL BOND RATINGS
 
    A  Standard & Poor's  municipal bond rating  is a current  assessment of the
creditworthiness of  an obligor  with  respect to  a specific  obligation.  This
assessment  may take into consideration obligors such as guarantors, insurers or
lessees.
 
    The ratings are  based on  current information  furnished by  the issuer  or
obtained  by Standard  & Poor's  from other  sources it  considers reliable. The
ratings are  based, in  varying degrees,  on the  following considerations:  (1)
likelihood  of default-capacity and willingness of  the obligor as to the timely
payment of interest and repayment of  principal in accordance with the terms  of
the  obligation;  (2)  nature  of  and provisions  of  the  obligation;  and (3)
protection afforded by, and relative position of the obligation in the event  of
bankruptcy, reorganization or other arrangement under the laws of bankruptcy and
other laws affecting creditors' rights.
 
    Standard  & Poor's does not  perform an audit in  connection with any rating
and may, on occasion, rely on  unaudited financial information. The ratings  may
be  changed, suspended or withdrawn as a result of changes in, or unavailability
of, such information, or for other reasons.
 
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.
 
                                       55
<PAGE>
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.
 
D     Debt rated "D" is in payment default. The 'D' rating category is used when
      interest  payments or principal payments are not made on the date due even
      if the applicable grace period has  not expired, unless S&P believes  that
      such  payments will be made during such  grace period. The 'D' rating also
      will be used  upon the  filing of a  bankruptcy petition  if debt  service
      payments are jeopardized.
 
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.

                             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  Standard  & Poor's  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.
 
   
<TABLE>
<S>        <C>
A-1        indicates that the degree of safety regarding timely payment is very strong.
 
A-2        indicates capacity  for timely  payment  on issues  with  this designation  is  strong.
           However,  the relative degree of safety is not as overwhelming as for issues designated
           "A-1."
 
A-3        indicates a  satisfactory  capacity  for  timely  payment.  Obligations  carrying  this
           designation are, however, somewhat more vulnerable to the adverse effects of changes in
           circumstances than obligations carrying the higher designations.

Item 27. Indemnification

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

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

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


                                        2

<PAGE>

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.

     SECTION 2.2. Other Offices. In addition to its principal office in the

of the Trust may require.

                                   ARTICLE III

                             SHAREHOLDERS' MEETINGS

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

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

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

     SECTION 3.4. Quorum and Adjournment of Meetings. Except as otherwise
provided by law, by the Declaration or by these By-Laws, at all meetings of
Shareholders the holders of a majority of the Shares



<PAGE>

issued and outstanding and entitled to vote thereat, present in person or
represented by proxy, shall be requisite and shall constitute a quorum for the
transaction of business. In the absence of a quorum, the Shareholders present or
represented by proxy and entitled to vote thereat shall have power to adjourn
the meeting from time to time. Any adjourned meeting may be held as adjourned
without further notice. At any adjourned meeting at which a quorum shall be
present, any business may be transacted as if the meeting had been held as
originally called.

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

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

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

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

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

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

                                   ARTICLE IV

                                    TRUSTEES

     SECTION 4.1. Meetings of the Trustees. The Trustees may in their discretion
provide for regular or special meetings of the Trustees. Regular meetings of the
Trustees may be held at such time and place as


                                        2
<PAGE>

shall be determined from time to time by the Trustees without further notice.
Special meetings of the Trustees may be called at any time by the President and
shall be called by the President or the Secretary upon the written request of
any two (2) Trustees.

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

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

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

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

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

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

     SECTION 4.8. Indemnification of Trustees, Officers, Employees and Agents.
(a) The Trust shall indemnify any person who was or is a party or is threatened
to be made a party to any threatened, pending, or completed action, suit or
proceeding, whether civil, criminal, administrative or investigative (other than
an action by or in the right of the Trust) by reason of the fact that he is or
was a Trustee, officer, employee, or agent of the Trust. The indemnification
shall be against expenses, including attorneys' fees, judgments, fines, and
amounts paid in settlement, actually and reasonably incurred by him in
connection with the action, suit, or proceeding, if he acted in good faith and
in a manner he reasonably believed to be in or not opposed to the best interests
of the Trust, and, with respect to any criminal action


                                        3
<PAGE>

or proceeding, had no reasonable cause to believe his conduct was unlawful. The
termination of any action, suit or proceeding by judgment, order, settlement,
conviction, or upon a plea of nolo contendere or its equivalent, shall not, of
itself, create a presumption that the person did not act in good faith and in a
manner which he reasonably believed to be in or not opposed to the best
interests of the Trust, and, with respect to any criminal action or proceeding,
had reasonable cause to believe that his conduct was unlawful.

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

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

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

          (2) The determination shall be made:

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

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

          (iii) By the Shareholders.

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

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

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

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

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


                                        4
<PAGE>

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

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

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

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

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

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

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

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

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

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

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

                                    ARTICLE V

                                   COMMITTEES

     SECTION 5.1. Executive and Other Committees. The Trustees, by resolution
adopted by a majority of the Trustees, may designate an Executive Committee
and/or committees, each committee to consist of two (2) or more of the Trustees
of the Trust and may delegate to such committees, in the intervals between
meetings of the Trustees, any or all of the powers of the Trustees in the
management of the business and affairs of the Trust. In the absence of any
member of any such committee, the members thereof present at any meeting,
whether or not they constitute a quorum, may appoint a Trustee to act in place
of such absent member. Each such committee shall keep a record of its
proceedings.

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


                                        5
<PAGE>

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

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

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

be a Chairman, a President, one or more Vice Presidents, a Secretary and a
Treasurer. The Chairman shall be selected from among the Trustees but none of

those of President and any Vice President, may be held by the same person, but
no officer shall execute, acknowledge or verify any instrument in more than one
capacity. The executive officers of the Trust shall be elected annually by the

successor is elected and has qualified.

     SECTION 6.2. Other Officers and Agents. The Trustees may also elect one or
more Assistant Vice Presidents, Assistant Secretaries and Assistant Treasurers

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

     SECTION 6.4. Compensation of Officers. The compensation of officers and
agents of the Trust shall be fixed by the Trustees, or by the Chairman to the
extent provided by the Trustees with respect to officers appointed by the

duties at such times and in such manner as he may deem advisable.

such other duties as the Board of Trustees may from time to time prescribe.

     SECTION 6.8. The Vice Presidents. The Vice Presidents shall be of such
number and shall have such titles as may be determined from time to time by the
Trustees. The Vice President, or, if there be more than one, the Vice Presidents

     SECTION 6.10. The Secretary. The Secretary shall attend all meetings of the
Trustees and all meetings of the Shareholders and record all the proceedings of
the meetings of the Shareholders and of the Trustees in a book to be kept for
that purpose, and shall perform like duties for the standing committees when
required. He shall give, or cause to be given, notice of all meetings of the
Shareholders and special meetings of the Trustees, and shall perform such other
duties and have such powers as the Trustees, or the President, may from time to
time prescribe. He shall keep in safe custody the seal of the Trust and affix or
cause the same to be affixed to any instrument requiring it, and, when so
affixed, it shall be attested by his signature or by the signature of an
Assistant Secretary.

     SECTION 6.11. The Assistant Secretaries. The Assistant Secretary, or, if
there be more than one, the Assistant Secretaries in the order determined by the
Trustees or the President, shall, in the absence or disability of the Secretary,

President, may from time to time prescribe.

     SECTION 6.13. The Assistant Treasurers. The Assistant Treasurer, or, if
there shall be more than one, the Assistant Treasurers in the order determined
by the Trustees or the President, shall, in the absence or disability of the
Treasurer, perform the duties and exercise the powers of the Treasurer and shall

other officer or officers or to any Trustee or Trustees.

                                   ARTICLE VII

                           DIVIDENDS AND DISTRIBUTIONS

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

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

                             CERTIFICATES OF SHARES

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

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

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

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

                                   ARTICLE IX

                                    CUSTODIAN

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

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

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

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

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

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


                                        8
<PAGE>

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

                                    ARTICLE X

                                WAIVER OF NOTICE

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

                                   ARTICLE XI

                                  MISCELLANEOUS

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

     SECTION 11.2. Record Date. The Trustees may fix in advance a date as the
record date for the purpose of determining Shareholders entitled to notice of,
or to vote at, any meeting of Shareholders, or Shareholders entitled to receive
payment of any dividend or the allotment of any rights, or in order to make a
determination of Shareholders for any other proper purpose. Such date, in any
case, shall be not more than ninety (90) days, and in case of a meeting of
Shareholders not less than ten (10) days, prior to the date on which particular
action requiring such determination of Shareholders is to be taken. In lieu of
fixing a record date the Trustees may provide that the transfer books shall be
closed for a stated period but not to exceed, in any case, twenty (20) days. If
the transfer books are closed for the purpose of determining Shareholders
entitled to notice of a vote at a meeting of Shareholders, such books shall be
closed for at least ten (10) days immediately preceding such meeting.

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

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

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

                       COMPLIANCE WITH FEDERAL REGULATIONS

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

                              DECLARATION OF TRUST

     The Declaration of Trust establishing Dean Witter New York Tax-Free Income
Fund, dated January 17, 1985, a copy of which is on file in the office of the
Secretary of the Commonwealth of Massachusetts, provides that the name Dean
Witter New York Tax-Free Income Fund refers to the Trustees under the

                         AMENDMENT TO CUSTODY AGREEMENT

     Amendment made as of this 17th day of April, 1996 by and between Dean
Witter New York Tax-Free Income Fund (the "Fund") and The Bank of New York (the
"Custodian") to the Custody Agreement between the Fund and the Custodian dated
September 20, 1991 (the "Custody Agreement"). The Custody Agreement is hereby
amended as follows:

     Article XV Section 8 of the Custody Agreement shall be deleted and be
replaced by Sections 8.(a), 8.(b) and 8.(c) as set forth below:

     8. (a) The Custodian will use reasonable care with respect to its
obligations under this Agreement and the safekeeping of Securities and moneys
owned by the Fund. The Custodian shall indemnify the Fund against and save the
Fund harmless from all liability, claims, losses and demands whatsoever,
including attorneys' fees, howsoever arising or incurred as the result of the
failure of a subcustodian which is a banking institution located in a foreign
country and identified on Schedule A attached hereto (each, a "Subcustodian") to
exercise reasonable care with respect to the safekeeping of such Securities and
moneys to the same extent that the Custodian would be liable to the Fund if the
Custodian were holding such securities and moneys in New York. In the event of
any loss to the Fund by reason of the failure of the Custodian or a Subcustodian
to utilize reasonable care, the Custodian shall be liable to the Fund only to
the extent of the Fund's direct damages, to be determined based on the market
value of the Securities and moneys which are the subject of the loss at the date
of discovery of such loss and without reference to any special conditions or
circumstances.

     8. (b) The Custodian shall not be liable for any loss which results from
(i) the general risk of investing, or (ii) investing or holding Securities and
moneys in a particular country including, but not limited to, losses resulting
from nationalization, expropriation or other governmental actions; regulation of
the banking or securities industry; currency restrictions, devaluations or
fluctuations; or market conditions which prevent the orderly execution of
securities transactions or affect the value of Securities or moneys.

       8. (c) Neither party shall be liable to the other for any loss due to
forces beyond its control including, but not limited to, strikes or work
stoppages, acts of war or terrorism, insurrection, revolution, nuclear fusion,
fission or radiation, or acts of God."
