SERVICES        Received  in  Cash;  Exchange  Privilege;  Systematic  Withdrawal  Plan; EasyInvest-SM-;
                Tax-Sheltered Retirement Plans (see page 14).
- -------------------------------------------------------------------------------------------------------
RISKS           The prices of interest-bearing securities are, generally, inversely affected by  changes
                in  interest rates and, therefore, are subject to the risk of market price fluctuations.
                The values of  fixed-income securities also  may be  affected by changes  in the  credit
                rating  or financial condition  of the issuing  entities. Mortgage-backed securities are
                subject to prepayments or refinancings of the mortgage pools underlying such  securities
                which  may have an impact upon  the yield and the net  asset value of the Fund's shares.
                Certain of  the mortgage-backed  securities in  which the  Fund may  invest have  higher
                yields  than traditional  mortgage-backed securities  and will  have concomitant greater
                price volatility. Asset-backed securities involve  risks resulting mainly from the  fact
                that  such securities do not usually contain the complete benefit of a security interest
                in the related collateral. Certain of the high yield, high risk fixed-income  securities
                in which the Fund may invest are subject to greater risk of loss of income and principal
                than the higher rated lower yielding fixed-income securities. The foreign securities and
                markets  in which the Fund  will invest pose different  and generally greater risks than
                those risks  customarily  associated  with domestic  securities  and  markets  including
                fluctuations  in foreign currency exchange rates, foreign tax rates and foreign exchange
                controls. (see page 6).

THE FUND AND ITS MANAGEMENT
- --------------------------------------------------------------------------------
 
Dean Witter Short-Term Bond Fund (the "Fund") is a no-load, open-end diversified
management investment company. The Fund is a trust of the type commonly known as
a  "Massachusetts  business  trust" and  was  organized  under the  laws  of The
Commonwealth of Massachusetts on October 22, 1993.
 
    Dean Witter InterCapital Inc. ("InterCapital" or the "Investment  Manager"),
whose address is Two World Trade Center, New York, New York 10048, is the Fund's
Investment  Manager.  The Investment  Manager, which  was incorporated  in July,
1992, is a wholly-owned  subsidiary of 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 ninety-seven investment companies, thirty of  which
are listed on the New York Stock Exchange, with combined assets of approximately
$81.8 billion at May 31, 1996. The Investment Manager also manages portfolios of
pension plans, other institutions and individuals which aggregated approximately
$2.8 billion at such date.
 
    The  Fund has  retained the  Investment Manager,  pursuant to  an Investment
Management Agreement, to  provide administrative services,  manage its  business
affairs and manage the investment of the Fund's assets, including the placing of
orders  for  the purchase  and sale  of  portfolio securities.  InterCapital has
retained Dean Witter Services
 
Company Inc. to perform the aforementioned administrative services to the Fund.
 
    The Fund's Board of  Trustees reviews the various  services provided by  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 rate of  0.70% to the  Fund's net assets  determined as of  the
close  of each business day. The Investment Manager had undertaken to assume all
operating expenses (except for  any brokerage fees)  and waive the  compensation
provided  for in its Investment Management Agreement until such time as the Fund
has $50 million  of net assets  or until December  31, 1995, whichever  occurred
first.  The  Investment  Manager has  undertaken  from January  1,  1996 through
December 31, 1996 to continue to  assume all operating expenses (except for  any
brokerage  fees)  and  to continue  to  waive  compensation to  the  extent such
expenses and compensation exceed on an annualized basis 1.0% of the Fund's daily
net assets. For the  fiscal year ended  April 30, 1996,  the Fund accrued  total
compensation  to the Investment Manager of 0.16% of the Fund's average daily net
assets and the Fund's total expenses amounted to an annual rate of 0.37% of  the
Fund's average daily net assets exclusive of any waivers.
 
INVESTMENT OBJECTIVE AND POLICIES
- --------------------------------------------------------------------------------
 
The  investment objective of the Fund is  to provide investors with a high level
of current income, consistent with the preservation of capital. This  investment
objective  is a fundamental policy of the Fund  and, as such, may not be altered
without the approval of the shareholders of the Fund. There is no assurance that
the Fund will achieve its investment objective.
 
    The  Fund  seeks  to  achieve  its  investment  objective  by  investing  in
short-term,  fixed-income  securities with  a dollar-weighted  average portfolio
maturity of less than three years. The Fund may invest in nominally  longer-term
securities  that  have many  of the  characteristics of  shorter-term securities
which will be  deemed to have  maturities earlier than  their ultimate  maturity
dates  (E.G., securities  with demand  features). A  substantial portion  of the
Fund's  portfolio  will  consist  of  fixed-income  securities  issued  by  U.S.
corporate   issuers   and   by   the   U.S.   Government,   its   agencies   and
instrumentalities.
 
    Under normal market conditions, at least 65% of the Fund's total assets will
be invested in bonds (for purposes of this provision, debt securities, which had
at time  of  issuance a  maturity  of greater  than  one year,  are  defined  as
"bonds").  Furthermore, a  portion of  the Fund's  portfolio (up  to 25%  of the
Fund's total  assets)  may be  invested  in fixed-income  securities  issued  by
foreign corporate and government issuers.
 
    The  Fund is designed for the investor who seeks a higher yield than a money
market fund and  less fluctuation  in net asset  value than  a longer-term  bond
fund.  In addition, while an investment in the Fund is not federally insured and
there is no guarantee of  price stability (the Fund is  not a money market  fund
with  a virtually  constant net  asset value  per share),  an investment  in the
Fund--unlike a certificate  of deposit  ("CD")--is not frozen  for any  specific
period  of time, may be redeemed at  any time without incurring early withdrawal
penalties, and may also provide a higher yield.
 
    The non-governmental  debt securities  in which  the Fund  will invest  will
include:  (a) corporate debt  securities, including bonds,  notes and commercial
paper,  rated  in  the  four  highest  categories  by  a  nationally  recognized
statistical
 
                                                                               5
<PAGE>
rating   organization  ("NRSRO")  including  Moody's  Investors  Service,  Inc.,
Standard &  Poor's  Corporation,  Duff  and Phelps,  Inc.  and  Fitch  Investors
Service,  Inc.; (b)  bank obligations,  including CDs,  banker's acceptances and
time deposits, issued by  banks with a  long-term CD rating in  one of the  four
highest  categories  by  a  NRSRO;  and  (c)  investment  grade  fixed-rate  and
adjustable rate  Mortgage-Backed  and  Asset-Backed securities  (see  below)  of
corporate  issuers.  Investments in  securities  rated within  the  four highest
rating categories by a  NRSRO are considered  "investment grade." However,  such
securities  rated within the fourth highest rating  category by a NRSRO 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. Where a fixed-income security is not rated by a NRSRO (as
may be the  case with a  foreign security)  the Investment Manager  will make  a
determination of its creditworthiness and may deem it to be investment grade.
    The  Fund  may also  invest in  preferred stocks  rated in  one of  the four
highest categories by a NRSRO.
    Up to 5% of the Fund's net assets may be invested in fixed-income securities
rated below investment grade. Such  lower-rated securities are considered to  be
speculative investments and, while producing higher yields than investment grade
securities,  are subject  to greater  credit risks. The  Fund does  not have any
minimum quality rating standards with respect to this portion of its  portfolio.
If an investment grade fixed-income security held by the Fund is downgraded by a
rating  agency  to a  grade below  investment  grade, the  Fund may  retain such
security in its  portfolio unless  such downgraded security,  together with  all
other  non-investment grade fixed-income securities held by the Fund constitute,
in the aggregate,  more than 5%  of the Fund's  net assets. In  such event,  the
Investment Manager will seek to sell such securities from its portfolio, as soon
as  is reasonably  practicable, in  sufficient amounts  to reduce  this total to
below 5% of its  net assets. A description  of fixed-income security ratings  is
contained in the Appendix to the Statement of Additional Information.
    The  United States Government securities  (including zero coupon securities)
in which the Fund will invest include securities which are direct obligations of
the United States Government,  such as United States  treasury bills, and  which
are  backed by the full faith and  credit of the United States; securities which
are backed by  the full  faith and  credit of the  United States  but which  are
obligations  of a United States agency  or instrumentality (E.G., obligations of
the Government National  Mortgage Association);  securities issued  by a  United
States  agency or  instrumentality which  has the right  to borrow,  to meet its
obligations, from an  existing line of  credit with the  United States  Treasury
(E.G.,  obligations of  the Federal  National Mortgage  Association); securities
issued by  a United  States agency  or instrumentality  which is  backed by  the
credit  of  the  issuing agency  or  instrumentality (E.G.,  obligations  of the
Federal  Farm  Credit   System);  and   governmentally  issued   mortgage-backed
securities.
    In  addition, as stated above,  up to 25% of the  Fund's total assets may be
invested in securities issued by foreign corporations and governments and  their
agencies  and instrumentalities. Such  securities may be  denominated in foreign
currencies. The principal foreign  currencies in which  such securities will  be
denominated  are:  the Australian  dollar; Deutsche  mark; Japanese  yen; French
franc; British pound; Canadian dollar; Mexican peso; Swiss franc; Dutch guilder;
Austrian schilling; Spanish Peseta; Swedish  Krona; and European Currency  Unit.
The  Fund will only invest  in foreign securities which are  rated by a NRSRO as
investment grade or which, if unrated,  are deemed by the Investment Manager  to
be of investment grade creditworthiness.
 
RISKS AND PORTFOLIO CHARACTERISTICS
MORTGAGE-BACKED   SECURITIES.    As  stated  above,  a  portion  of  the  Fund's
investments may be in Mortgage-Backed securities. Mortgage-Backed securities are
securities that  directly or  indirectly represent  a participation  in, or  are
secured  by and payable from, mortgage loans  secured by real property. The term
Mortgage-Backed securities  as used  herein  includes adjustable  rate  mortgage
securities  and  derivative mortgage  products  such as  collateralized mortgage
obligations, stripped Mortgage-Backed  securities and  other products  described
below.
    There  are currently  three basic  types of  Mortgage-Backed securities: (i)
those issued  or  guaranteed by  the  United States  Government  or one  of  its
agencies   or  instrumentalities,  such  as  the  Government  National  Mortgage
Association ("GNMA"), the Federal National Mortgage Association ("FNMA") and the
Federal Home Loan Mortgage Corporation ("FHLMC") (securities issued by GNMA, but
not those issued by FNMA or FHLMC, are backed by the "full faith and credit"  of
the  United  States); (ii)  those issued  by private  issuers that  represent an
interest in  or  are  collateralized by  Mortgage-Backed  securities  issued  or
guaranteed   by  the  United  States  Government  or  one  of  its  agencies  or
instrumentalities; and (iii) those issued  by private issuers that represent  an
interest  in or  are collateralized by  whole mortgage  loans or Mortgage-Backed
securities without  a  government guarantee  but  usually having  some  form  of
private credit enhancement (described below).
    The  Fund  will  invest  in  mortgage  pass-through  securities representing
participation interests in  pools of  residential mortgage  loans originated  by
United  States governmental  or private  lenders and  guaranteed, to  the extent
provided in  such securities,  by the  United States  Government or  one of  its
agencies or instrumentalities. Such secu-
 
6
<PAGE>
rities,  which are ownership interests in  the underlying mortgage loans, differ
from conventional  debt  securities,  which  provide  for  periodic  payment  of
interest  in  fixed amounts  (usually  semiannually) and  principal  payments at
maturity or on  specified call dates.  Mortgage pass-through securities  provide
for  monthly  payments that  are a  "pass-through" of  the monthly  interest and
principal payments (including any prepayments) made by the individual  borrowers
on  the pooled  mortgage loans, net  of any fees  paid to the  guarantor of such
securities and the servicer of the underlying mortgage loans.
 
    The guaranteed mortgage  pass-through securities in  which the Fund  invests
include  those issued or  guaranteed by GNMA, FNMA  and FHLMC. GNMA certificates
are direct obligations of the  U.S. Government and, as  such, are backed by  the
"full  faith and credit"  of the United  States. FNMA is  a federally chartered,
privately owned  corporation and  FHLMC is  a corporate  instrumentality of  the
United  States. FNMA and FHLMC certificates are not backed by the full faith and
credit of the United  States but the issuing  agency or instrumentality has  the
right  to borrow, to meet its obligations,  from an existing line of credit with
the U.S. Treasury.  The U.S. Treasury  has no legal  obligation to provide  such
line of credit and may choose not to do so.
 
    Certificates  for  Mortgage-Backed  securities  evidence  an  interest  in a
specific pool of  mortgages. These  certificates are, in  most cases,  "modified
pass-through"  instruments, wherein the issuing agency guarantees the payment of
principal and interest on mortgages underlying the certificates, whether or  not
such amounts are collected by the issuer on the underlying mortgages.
 
    Private  mortgage pass-through  securities are  structured similarly  to the
GNMA, FNMA  and  FHLMC  mortgage  pass-through  securities  and  are  issued  by
originators  of  and investors  in mortgage  loans,  including savings  and loan
associations, mortgage  banks, commercial  banks, investment  banks and  special
purpose  subsidiaries of the foregoing. These securities usually are backed by a
pool of conventional fixed rate or adjustable rate mortgage loans. Since private
mortgage pass-through  securities  typically are  not  guaranteed by  an  entity
having  the credit status of GNMA, FNMA and FHLMC, such securities generally are
structured with one or more types of credit enhancement.
 
    The Fund may also  invest in adjustable  rate mortgage securities  ("ARMs"),
which  are  pass-through mortgage  securities  collateralized by  mortgages with
adjustable rather than fixed  rates. ARMs eligible for  inclusion in a  mortgage
pool generally provide for a fixed initial mortgage interest rate for either the
first  three,  six,  twelve  or  thirteen,  twenty-four,  thirty-six  or  longer
scheduled monthly  payments.  Thereafter,  the interest  rates  are  subject  to
periodic  adjustment  based on  changes to  a  designated benchmark  index. ARMs
contain maximum and minimum  rates beyond which the  mortgage interest rate  may
not  vary over the lifetime  of the security. In  addition, certain ARMs provide
for additional limitations on the maximum amount by which the mortgage  interest
rate  may adjust for  any single adjustment  period. Alternatively, certain ARMs
contain limitations on  changes in the  required monthly payment.  In the  event
that a monthly payment is not sufficient to pay the interest accruing on an ARM,
any such excess interest is added to the principal balance of the mortgage loan,
which is repaid through future monthly payments. If the monthly payment for such
an instrument exceeds the sum of the interest accrued at the applicable mortgage
interest  rate and the principal payment required  at such point to amortize the
outstanding principal balance over the remaining term of the loan, the excess is
utilized to reduce the then outstanding principal balance of the ARM.
 
COLLATERALIZED MORTGAGE  OBLIGATIONS.   The Fund  may invest  in  collateralized
mortgage  obligations  or "CMOs".  CMOs are  debt obligations  collateralized by
mortgage  loans  or  mortgage  pass-through  securities.  Typically,  CMOs   are
collateralized   by  GNMA,  FNMA,  or  FHLMC   certificates,  but  also  may  be
collateralized by whole loans or private mortgage pass-through securities  (such
collateral  is  collectively  hereinafter  referred  to  as  "Mortgage Assets").
Multiclass pass-through securities are equity  interests in a trust composed  of
Mortgage  Assets. Payments of principal of  and interest on the Mortgage Assets,
and any reinvestment income  thereon, provide the funds  to pay debt service  on
the  CMOs  or  make  scheduled  distributions  on  the  multiclass  pass-through
securities. CMOs may be  issued by agencies or  instrumentalities of the  United
States  Government,  or by  private originators  of,  or investors  in, mortgage
loans, including  savings  and  loan associations,  mortgage  banks,  commercial
banks, investment banks and special purpose subsidiaries of the foregoing.
 
    The  issuer of a  series of CMOs  may elect to  be treated as  a Real Estate
Mortgage  Investment  Conduit  ("REMIC").  REMICs  include  governmental  and/or
private  entities that issue a fixed pool of mortgages secured by an interest in
real property. REMICs are similar to CMOs in that they issue multiple classes of
securities, but  unlike  CMOs, which  are  required  to be  structured  as  debt
securities,  REMICs may  be structured  as indirect  ownership interests  in the
underlying assets of the REMICs themselves. However, there are no effects on the
Fund from investing in CMOs issued by  entities that have elected to be  treated
as  REMICs, and all  future references to  CMOs shall also  be deemed to include
REMICs. In addition,  in reliance  upon an interpretation  by the  staff of  the
Securities  and  Exchange Commission  with respect  to limitations  contained in
Section 12(d) of the  Act, the Fund  may invest without  limitation in CMOs  and
other  Mortgage-Backed securities which are not  by definition excluded from the
provisions of  the Act,  and  which have  obtained  exemptive orders  from  such
provisions from the Securities and Exchange Commission.
 
    In  a CMO, a series of bonds  or certificates is issued in multiple classes.
Each class of CMOs, often  referred to as a "tranche",  is issued at a  specific
fixed or floating coupon
 
                                                                               7
<PAGE>
rate and has a stated maturity or final distribution date. Principal prepayments
on  the Mortgage Assets may  cause the CMOs to  be retired substantially earlier
than their stated maturities  or final distribution dates.  Interest is paid  or
accrues  on all classes of the CMOs on a monthly, quarterly or semiannual basis.
Certain CMOs may  have variable  or floating interest  rates and  others may  be
stripped (securities which provide only the principal or interest feature of the
underlying security).
 
    The  principal of and interest on the Mortgage Assets may be allocated among
the several classes of a  CMO series in a  number of different ways.  Generally,
the  purpose of the allocation of the cash  flow of a CMO to the various classes
is to obtain a more predictable cash flow to the individual tranches than exists
with the  underlying  collateral  of  the  CMO. As  a  general  rule,  the  more
predictable  the cash flow is on a  CMO tranche, the lower the anticipated yield
will be on that tranche  at the time of  issuance relative to prevailing  market
yields  on Mortgage-Backed securities.  As part of the  process of creating more
predictable cash flows on most of the tranches in a series of CMOs, one or  more
tranches  generally must be  created that absorb  most of the  volatility in the
cash flows on the  underlying mortgage loans. The  yields on these tranches  are
generally  higher than  prevailing markets yields  on Mortgage-Backed securities
with similar maturities. As  a result of  the uncertainty of  the cash flows  of
these  tranches, the market prices of and  yield on these tranches generally are
more volatile.
 
    The Fund may  invest up  to 10%  of its  total assets  in inverse  floaters.
Inverse  floaters  constitute a  class of  CMOs  with a  coupon rate  that moves
inversely to a designated  index, such as the  LIBOR (London Inter-Bank  Offered
Rate)  Index.  Inverse floaters  have coupon  rates that  typically change  at a
multiple of the changes of the relevant  index rate. Any rise in the index  rate
(as  a consequence of an increase in interest rates) causes a drop in the coupon
rate of an inverse floater while any  drop in the index rate causes an  increase
in  the coupon of an inverse floater.  In addition, like most other fixed-income
securities, the  value  of inverse  floaters  will decrease  as  interest  rates
increase. Inverse floaters exhibit greater price volatility than the majority of
mortgage  pass-through securities  or CMOs.  In addition,  some inverse floaters
exhibit extreme sensitivity to changes in prepayments. As a result, the yield to
maturity of an  inverse floater  is sensitive not  only to  changes in  interest
rates but also to changes in prepayment rates on the related underlying Mortgage
Assets.
 
    The  Fund also  may invest  in, among  other things,  parallel pay  CMOs and
Planned Amortization Class CMOs ("PAC Bonds"). Parallel pay CMOs are  structured
to  provide payments of principal  on each payment date  to more than one class.
These simultaneous payments  are taken  into account in  calculating the  stated
maturity date or final distribution date of each class, which, as with other CMO
structures,  must be retired  by its stated maturity  date or final distribution
date but  may be  retired earlier.  PAC Bonds  generally require  payments of  a
specified  amount  of  principal on  each  payment  date. PAC  Bonds  always are
parallel pay CMOs with the required principal payment on such securities  having
the highest priority after interest has been paid to all classes.
 
STRIPPED  MORTGAGE-BACKED SECURITIES.   Stripped  Mortgage-Backed securities are
derivative multiclass mortgage  securities. Stripped Mortgage-Backed  securities
may  be issued by agencies or instrumentalities of the United States Government,
or by private originators of, or investors in, mortgage loans, including savings
and loan associations,  mortgage banks, commercial  banks, investment banks  and
special  purpose subsidiaries of the  foregoing. Up to 15%  of the net assets of
the Fund may be invested in Stripped Mortgage-Backed Securities.
 
    Stripped Mortgage-Backed securities usually are structured with two  classes
that receive different proportions of the interest and principal distribution on
a  pool of Mortgage  Assets. A common type  of Stripped Mortgage-Backed security
will have one class  receiving some of  the interest and  most of the  principal
from  the  Mortgage Assets,  while  the other  class  will receive  most  of the
interest and the remainder of the principal. In the most extreme case, one class
will receive all of  the interest (the interest-only  or "IO" class), while  the
other  class receive all of the principal (the principal-only or "PO" class). PO
classes generate income through the accretion of the deep discount at which such
securities are purchased, and, while PO classes do not receive periodic payments
of  interest,   they  receive   monthly  payments   associated  with   scheduled
amortization and principal prepayment from the Mortgage Assets underlying the PO
class.  The yield to maturity on an IO  class is extremely sensitive to the rate
of principal payments (including prepayments) on the related underlying Mortgage
Assets, and  a rapid  rate of  principal payments  may have  a material  adverse
effect  on  the Fund's  yield  to maturity.  If  the underlying  Mortgage Assets
experience greater than anticipated prepayments of principal, the Fund may  fail
to  fully  recoup  its  initial  investment  in  these  securities  even  if the
securities are rated investment grade.
 
    The Fund may purchase Stripped Mortgage-Backed securities for income, or for
hedging  purposes  to  protect  the  Fund's  portfolio  against  interest   rate
fluctuations.  For example, since an IO class  will tend to increase in value as
interest rates rise, it may be utilized to hedge against a decrease in value  of
other  fixed-income securities in a rising interest rate environment. The Fund's
management understands that the staff of the Securities and Exchange  Commission
("SEC")   considers   privately  issued   Stripped   Mortgage-Backed  securities
representing interest only or  principal only components  of U.S. Government  or
other  debt  securities to  be  illiquid securities.  The  Fund will  treat such
securities as illiquid so long as  the staff maintains such position. The  staff
of  the  SEC  also  takes  the position  that  the  determination  of  whether a
particular government-issued IO or PO  backed by fixed-rate mortgages is  liquid
 
8
<PAGE>
may  be made under guidelines and  standards established by the Fund's Trustees.
Such securities may be deemed liquid if they can be disposed of promptly in  the
ordinary  course of  business at a  value reasonably  close to that  used in the
calculation of the net asset value per share. The Fund may not invest more  than
15% of its net assets in illiquid securities.
 
TYPES  OF CREDIT ENHANCEMENT.  Mortgage-Backed  securities are often backed by a
pool of assets representing the obligations of a number of different parties. To
lessen the effect of failures by obligors on underlying assets to make payments,
those securities may  contain elements of  credit support, which  fall into  two
categories:   (i)  liquidity  protection  and  (ii)  protection  against  losses
resulting from  ultimate  default  by  an  obligor  on  the  underlying  assets.
Liquidity  protection  refers to  the provision  of  advances, generally  by the
entity administering the pool of assets, to ensure that the receipt of  payments
on  the underlying  pool occurs in  a timely fashion.  Protection against losses
resulting from default ensures ultimate payment of the obligations on at least a
portion of  assets  in  the  pool.  This  protection  may  be  provided  through
guarantees,  insurance policies or  letters of credit obtained  by the issuer or
sponsor from third parties, through various means of structuring the transaction
or through  a combination  of  such approaches.  The  degree of  credit  support
provided  for each issue is generally based on historical information respecting
the level of credit risk associated with the underlying assets. Delinquencies or
losses in excess of  those anticipated could adversely  affect the return on  an
investment in a security. In addition, any circumstances adversely affecting the
ability  of third  parties (E.G., insurance  companies) to satisfy  any of their
obligations with respect to any Mortgage-Backed security, such as a diminishment
of their creditworthiness, could adversely affect the value of the security. The
Fund will not pay any fees for credit support, although the existence of  credit
support may increase the price of a security.
 
RISKS  OF MORTGAGE-BACKED  SECURITIES.  Mortgage-Backed  securities have certain
different characteristics  than traditional  debt  securities. Among  the  major
differences  are that interest and principal  payments are made more frequently,
usually monthly,  and that  principal may  be prepaid  at any  time because  the
underlying  mortgage loans or other assets generally may be prepaid at any time.
As a result, if the  Fund purchases such a security  at a premium, a  prepayment
rate  that  is faster  than  expected will  reduce  yield to  maturity,  while a
prepayment rate that is  slower than expected will  have the opposite effect  of
increasing  yield  to  maturity.  Alternatively,  if  the  Fund  purchases these
securities at a discount, faster than expected prepayments will increase,  while
slower  than expected prepayments  will reduce, yield to  maturity. The Fund may
invest a portion of its assets in derivative Mortgage-Backed securities such  as
Stripped  Mortgage-Backed securities  which are  highly sensitive  to changes in
prepayment and  interest rates.  The Investment  Manager seeks  to manage  these
risks  (and potential benefits) by investing in a variety of such securities and
through hedging techniques.
 
    Mortgage-Backed securities,  like  all fixed  income  securities,  generally
decrease  in value  as a  result of  increases in  interest rates.  In addition,
although generally the value of fixed-income securities increases during periods
of falling interest  rates and,  as stated  above, decreases  during periods  of
rising interest rates, as a result of prepayments and other factors, this is not
always the case with respect to Mortgage-Backed securities.
 
    Although  the extent of prepayments  on a pool of  mortgage loans depends on
various economic and other factors, as a general rule prepayments on fixed  rate
mortgage  loans  will increase  during a  period of  falling interest  rates and
decrease  during  a  period  of  rising  interest  rates.  Accordingly,  amounts
available  for reinvestment by the Fund are likely to be greater during a period
of declining interest rates and, as a  result, likely to be reinvested at  lower
interest  rates than during  a period of  rising interest rates. Mortgage-Backed
securities generally decrease  in value  as a  result of  increases in  interest
rates  and may  benefit less than  other fixed-income  securities from declining
interest rates because of the risk of prepayment.
 
    There are certain risks  associated specifically with  CMOs. CMOs issued  by
private  entities are not  U.S. Government securities and  are not guaranteed by
any government agency, although the securities  underlying a CMO may be  subject
to  a guarantee. Therefore, if  the collateral securing the  CMO, as well as any
third party credit support or guarantees,  is insufficient to make payment,  the
holder  could sustain a loss. Also, a number of different factors, including the
extent  of  prepayment  of  principal   of  the  Mortgage  Assets,  affect   the
availability  of cash for  principal payments by  the CMO issuer  on any payment
date and,  accordingly, affect  the timing  of principal  payments on  each  CMO
class. In addition, CMO classes with higher yields tend to be more volatile with
respect  to cash flow of the underlying mortgages; as a result the market prices
of a yield on these classes tend to be more volatile.
 
ASSET-BACKED SECURITIES.    The  Fund may  invest  in  Asset-Backed  securities.
Asset-Backed  securities represent the securitization techniques used to develop
Mortgage-Backed securities applied to a broad range of other assets. Through the
use of  trusts  and  special  purpose corporations,  various  types  of  assets,
primarily  automobile and  credit card  receivables and  home equity  loans, are
being  securitized   in  pass-through   structures  similar   to  the   mortgage
pass-through structures described above or in a pay-through structure similar to
the CMO structure.
 
    Asset-Backed  securities  involve  certain  risks  that  are  not  posed  by
Mortgage-Backed securities,  resulting mainly  from the  fact that  Asset-Backed
securities do not usually contain the complete benefit of a security interest in
the  related  collateral. For  example,  credit card  receivables  generally are
unsecured and the debtors are entitled to the
 
                                                                               9
<PAGE>
protection of a number of state and federal consumer credit laws, including  the
bankruptcy laws, some of which may reduce the ability to obtain full payment. In
the  case of automobile receivables, due  to various legal and economic factors,
proceeds for  repossessed collateral  may not  always be  sufficient to  support
payments on these securities.
 
    New  instruments and  variations of existing  Mortgage-Backed securities and
Asset-Backed securities continue  to be developed.  The Fund may  invest in  any
such  instruments or  variations as may  be developed, to  the extent consistent
with  its   investment  objective   and  policies   and  applicable   regulatory
requirements.
 
FOREIGN  SECURITIES.  Foreign securities investments  may be affected by changes
in currency  rates  or exchange  control  regulations, changes  in  governmental
administration  or economic or monetary policy (in the United States and abroad)
or changed  circumstances  in  dealings between  nations.  Fluctuations  in  the
relative  rates of  exchange between  the currencies  of different  nations will
affect the  value of  the Fund's  investments denominated  in foreign  currency.
Changes  in foreign  currency exchange  rates relative  to the  U.S. dollar will
affect the U.S. dollar value of  the Fund's assets denominated in that  currency
and thereby impact upon the Fund's total return on such assets.
 
    Foreign  currency  exchange rates  are determined  by  forces of  supply and
demand on the foreign exchange markets. These forces are themselves affected  by
the   international  balance  of  payments  and  other  economic  and  financial
conditions, government intervention,  speculation and  other factors.  Moreover,
foreign currency exchange rates may be affected by the regulatory control of the
exchanges  on which the  currencies trade. The  foreign currency transactions of
the Fund will  be conducted  on a  spot basis  or through  forward contracts  or
futures  contracts (described in  the Statement of  Additional Information). The
Fund will incur certain costs in connection with these currency transactions.
 
    Investments in  foreign  securities will  also  occasion risks  relating  to
political  and  economic  developments  abroad,  including  the  possibility  of
expropriations or confiscatory taxation, limitations  on the use or transfer  of
Fund   assets  and  any  effects  of   foreign  social,  economic  or  political
instability. Foreign companies are not subject to the regulatory requirements of
U.S. companies and, as  such, there may be  less publicly available  information
about  such companies. Moreover,  foreign companies are not  subject to the more
rigorous uniform  accounting, auditing  and  financial reporting  standards  and
requirements applicable to U.S. companies.
 
    Securities  of foreign issuers may be less liquid than comparable securities
of U.S.  issuers  and,  as such,  their  price  changes may  be  more  volatile.
Furthermore,  foreign exchanges and broker-dealers are generally subject to less
government  and   exchange  scrutiny   and   regulation  than   their   American
counterparts.  Brokerage commissions,  dealer concessions  and other transaction
costs may be higher on foreign markets than in the U.S. In addition, differences
in clearance and settlement procedures on foreign markets may occasion delays in
settlements of Fund  trades effected in  such markets. Inability  to dispose  of
portfolio securities due to settlement delays could result in losses to the Fund
due  to subsequent declines in value of such securities and the inability of the
Fund to make intended security purchases due to settlement problems could result
in a failure of  the Fund to make  potentially advantageous investments. To  the
extent  the Fund purchases Eurodollar certificates  of deposit issued by foreign
branches of domestic United States banks,  consideration will be given to  their
domestic  marketability, the  lower reserve  requirements normally  mandated for
overseas banking operations, the possible impact of interruptions in the flow of
international currency  transactions,  and future  international  political  and
economic  developments which might adversely affect  the payment of principal or
interest.
 
REPURCHASE AGREEMENTS.  The Fund may enter into repurchase agreements, which may
be viewed as a type of secured lending by the Fund, and which typically  involve
the  acquisition  by  the  Fund  of debt  securities  from  a  selling financial
institution such as a bank, savings  and loan association or broker-dealer.  The
agreement provides that the Fund will sell back to the institution, and that the
institution  will  repurchase,  the  underlying  security  ("collateral")  at  a
specified price and at a fixed time  in the future, usually not more than  seven
days from the date of purchase.
 
    While repurchase agreements involve certain risks not associated with direct
investments in debt securities, the Fund follows procedures designed to minimize
such  risks. These procedures include  effecting repurchase agreements only with
large,  well-capitalized  and  well-established  financial  institutions   whose
financial  condition  will be  continually monitored  by the  Investment Manager
subject to procedures established by the  Trustees of the Fund. In addition,  as
described above, the value of the collateral underlying the repurchase agreement
will  be at least equal to the  repurchase price, including any accrued interest
earned on the repurchase agreement. In the event of a default or bankruptcy by a
selling financial institution, the Fund will seek to liquidate such  collateral.
However,  the exercising of the Fund's  right to liquidate such collateral could
involve certain costs or delays and, to  the extent that proceeds from any  sale
upon  a default of  the obligation to  repurchase were less  than the repurchase
price, the Fund could suffer a loss.
 
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.   While    the
 
10
<PAGE>
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.  The
securities  so  purchased  or sold  are  subject  to market  fluctuation  and no
interest accrues to the purchaser during this period. At the time the Fund makes
the commitment to purchase or sell securities on a when-issued, delayed delivery
or forward  commitment basis,  it  will record  the transaction  and  thereafter
reflect  the value,  each day,  of such  security purchased  or, if  a sale, the
proceeds to be  received in  determining its  net asset  value. At  the time  of
delivery of the securities, their value may be more or less than the purchase or
sale price. The Fund will also establish a segregated account with its custodian
bank  in which it  will continually maintain  cash or cash  equivalents or other
high grade debt portfolio securities equal  in value to commitments to  purchase
securities  on a when-issued,  delayed delivery or  forward commitment basis. An
increase in the  percentage of the  Fund's assets committed  to the purchase  of
securities  on a when-issued,  delayed delivery or  forward commitment basis may
increase the volatility of the Fund's net asset value.
 
WHEN, AS AND IF ISSUED SECURITIES.  The Fund may purchase securities on a "when,
as and if issued" basis  under which the issuance  of the security depends  upon
the  occurrence of a subsequent  event, such as approval  of a merger, corporate
reorganization, leveraged buyout or debt  restructuring. The commitment for  the
purchase  of any  such security  will not  be recognized  by the  Fund until the
Investment Manager determines that issuance of the security is probable. At such
time, the Fund  will record the  transaction and, in  determining its net  asset
value, will reflect the value of the security daily. At such time, the Fund will
also  establish a segregated  account with its  custodian bank in  which it will
continuously maintain cash  or U.S.  Government securities or  other high  grade
debt  portfolio securities  equal in  value to  recognized commitments  for such
securities. Settlement of the trade will occur within five business days of  the
occurrence of the subsequent event. With respect to 75% of its total assets, the
value  of the Fund's commitments  to purchase the securities  of any one issuer,
together with the value of all securities of such issuer owned by the Fund,  may
not  exceed 5% of the value  of the Fund's total assets  at the time the initial
commitment to purchase such securities is made (see "Investment  Restrictions").
Subject  to the foregoing restrictions, 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, as and if issued" basis may
increase the volatility of its net  asset value. The Investment Manager and  the
Trustees  do not believe that the net asset  value of the Fund will be adversely
affected by its purchase of securities on such basis.
 
ZERO COUPON SECURITIES.  A portion  of the U.S. Government securities  purchased
by  the Fund may be  "zero coupon" Treasury securities.  These are U.S. Treasury
bills, notes and  bonds which  have been  stripped of  their unmatured  interest
coupons  and receipts or  which are certificates  representing interests in such
stripped  debt  obligations  and  coupons.   In  addition,  a  portion  of   the
fixed-income  securities purchased by such Fund may be "zero coupon" securities.
"Zero coupon" securities  are purchased at  a discount from  their face  amount,
giving  the purchaser the right to receive  their full value at maturity. A zero
coupon security pays no interest to its holder during its life. Its value to  an
investor  consists  of the  difference between  its  face value  at the  time of
maturity and the price for which it  was acquired, which is generally an  amount
significantly  less  than  its face  value  (sometimes  referred to  as  a "deep
discount" price).
 
    The  interest  earned  on  such  securities  is,  implicitly,  automatically
compounded  and paid out at maturity. While  such compounding at a constant rate
eliminates the risk of receiving lower  yields upon reinvestment of interest  if
prevailing  interest rates decline, the owner of  a zero coupon security will be
unable to participate in higher yields upon reinvestment of interest received if
prevailing interest  rates rise.  For this  reason, zero  coupon securities  are
subject  to substantially  greater market  price fluctuations  during periods of
changing prevailing interest  rates than  are comparable  debt securities  which
make  current distributions of interest. Current federal tax law requires that a
holder (such as  the Fund) of  a zero coupon  security accrue a  portion of  the
discount at which the security was purchased as income each year even though the
Fund receives no interest payments in cash on the securities during the year.
 
    Currently,  the only  U.S. Treasury security  issued without  coupons is the
Treasury bill. However, in the  last few years a  number of banks and  brokerage
firms  have  separated  ("stripped")  the  principal  portions  from  the coupon
portions of the U.S. Treasury  bonds and notes and  sold them separately in  the
form  of  receipts or  certificates  representing undivided  interests  in these
instruments (which instruments are  generally held by a  bank in a custodial  or
trust account).
 
    Except   as  specifically  noted,  all  investment  policies  and  practices
discussed in this Prospectus  are not fundamental policies  of the Fund and,  as
such, may be changed without shareholder approval.
 
PORTFOLIO MANAGEMENT
 
The  Fund's  portfolio is  managed  by its  Investment  Manager with  a  view to
achieving its investment objective.  The Fund is  managed within Taxable  Income
Group,  which managed  approximately $13.5  billion in  assets at  May 31, 1996.
Rochelle G.  Siegel, Senior  Vice  President of  InterCapital  and a  member  of
InterCapital's  Corporate Bond Group, has been  designated as the Fund's primary
portfolio  manager.  Ms.  Siegel  has  been  managing  portfolios  comprised  of
fixed-income securities at InterCapital for over five years.
 
                                                                              11
<PAGE>
    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
money market instruments with Dean Witter Reynolds Inc. ("DWR"), a broker-dealer
affiliate of the Investment Manager. In  addition, the Fund may incur  brokerage
commissions on transactions conducted through DWR.
 
    Although  the  Fund  does not  intend  to engage  in  substantial short-term
trading, it may sell portfolio securities  without regard to the length of  time
that  they  have  been  held,  in order  to  take  advantage  of  new investment
opportunities or yield differentials,  or because the  Fund desires to  preserve
gains or limit losses due to changing economic conditions, interest rate trends,
or  the  financial condition  of the  issuer. The  Fund anticipates  a portfolio
turnover rate of no more than 100%.
 
INVESTMENT IN OTHER INVESTMENT  VEHICLES.  Under the  Investment Company Act  of
1940,  as amended (the  "Act"), the Fund generally  may invest up  to 10% of its
total assets in the aggregate in shares of other investment companies and up  to
3% of its total assets in any one investment company, as long as that investment
company  does not  represent more than  5% of  the voting stock  of the acquired
investment company at the time such shares are purchased. In addition, the  Fund
may  invest in  real estate investment  trusts, which pool  investors' funds for
investments primarily in commercial real estate properties. Investment in  other
investment  companies may be the sole or  most practical means by which the Fund
may participate in  certain securities  markets, and investment  in real  estate
investment  trusts may  be the  most practical available  means for  the Fund to
invest in the  real estate industry  (the Fund is  prohibited from investing  in
real  estate directly). As a shareholder in an investment company or real estate
investment trust,  the  Fund would  bear  its  ratable share  of  that  entity's
expenses,  including its advisory and administration  fees. At the same time the
Fund would  continue  to  pay  its own  investment  management  fees  and  other
expenses,  as a result of which the Fund  and its shareholders in effect will be
absorbing duplicate  levels  of  fees  with  respect  to  investments  in  other
investment companies and in real estate investment trusts.
 
INVESTMENT RESTRICTIONS
- --------------------------------------------------------------------------------
 
The  investment restrictions listed  below are among  the restrictions that have
been adopted by the Fund as  fundamental policies. Under the Act, a  fundamental
policy  may not  be changed without  the vote  of a majority  of the outstanding
voting securities of the Fund, as defined in the Act.
 
    The Fund may not:
 
        1. As to 75% of  its total assets, invest more  than 5% of the value  of
    its total assets in the securities of any one issuer (other than obligations
    issued,  or guaranteed  by, the  United States  Government, its  agencies or
    instrumentalities).
 
        2. As  to  75% of  its  total assets,  purchase  more than  10%  of  all
    outstanding voting securities or any class of securities of any one issuer.
 
        3.  Invest 25% or more 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 or  its agencies or
    instrumentalities.
 
        4. Invest more than 5% of the value of its total assets in securities of
    issuers having  a record,  together with  predecessors, of  less than  three
    years   of  continuous  operation.  This  restriction  shall  not  apply  to
    Mortgage-Backed securities or Asset-Backed  securities or to any  obligation
    of the United States Government, its agencies or instrumentalities.
 
    If a percentage restriction is adhered to at the time of investment, a later
increase  or  decrease  in  percentage  resulting from  a  change  in  values of
portfolio securities or amount of total or  net assets will not be considered  a
violation of any of the foregoing restrictions.
 
PURCHASE OF FUND SHARES
- --------------------------------------------------------------------------------
 
The  Fund offers its shares for sale to  the public on a continuous basis at the
offering price without the imposition of a sales charge. The offering price will
be the net asset value per share  next determined following receipt of an  order
(see  "Determination of Net Asset Value").  Pursuant to a Distribution Agreement
between the  Fund and  Dean  Witter Distributors  Inc. (the  "Distributor"),  an
affiliate  of the Investment Manager, shares of  the Fund are distributed by the
Distributor and are offered by DWR  and other broker-dealers which have  entered
into  agreements with the Distributor ("Selected Broker-Dealers"). The principal
executive office of the  Distributor is located at  Two World Trade Center,  New
York, New York 10048.
 
    The  minimum initial purchase is $1,000  and subsequent purchases of $100 or
more may be  made by sending  a check,  payable to Dean  Witter Short-Term  Bond
Fund,  directly to Dean Witter Trust Company  (the "Transfer Agent") at P.O. Box
1040, Jersey City,  NJ 07303 or  by contacting  an account executive  of DWR  or
other Selected
 
12
<PAGE>
Broker-Dealers.  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. In  the
case of investments pursuant to Systematic Payroll Deduction Plans, the Fund, in
its  discretion, may  accept investments without  regard to  any minimum amounts
which would  otherwise  be required  if  the Fund  has  reason to  believe  that
additional  investments will increase the investment  in all accounts under such
Plans to at least $1,000. Certificates  for shares purchased will not be  issued
unless a request is made by the shareholder in writing to the Transfer Agent.
 
    Shares  of  the  Fund  are  sold  through  the  Distributor  or  a  Selected
Broker-Dealer on a normal three business day settlement basis; that is,  payment
is  due on the  third business day  (settlement date) after  the order is placed
with the Distributor or Selected Broker-Dealer. Since DWR or any other  Selected
Broker-Dealer  may forward investors' funds on  settlement date, it will benefit
from the temporary use of the funds  if payment is made prior thereto. As  noted
above,  orders placed  directly with the  Transfer Agent must  be accompanied by
payment. Investors will  be entitled  to receive dividends  or distributions  if
their  order is received by the close of business on the day prior to the record
date for such dividends and distributions.
 
    Sales personnel of a  Selected Broker-Dealer are  compensated for shares  of
the  Fund sold by them by  the Distributor or any of  its affiliates and/or by a
Selected Broker-Dealer.  In  addition,  some sales  personnel  of  the  Selected
Broker-Dealer  will receive  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.
 
PLAN OF DISTRIBUTION
 
The Fund has entered into  a Plan of Distribution  pursuant to Rule 12b-1  under
the  Act with the  Distributor whereby the Distributor  is authorized to utilize
its own resources or those of its affiliates, including InterCapital, to finance
certain services  and activities  in  connection with  the distribution  of  the
Fund's  shares. The principal  activities and services which  may be provided by
the Distributor, DWR, its affiliates and other Selected Broker-Dealers under the
Plan include: (1) compensation to, and expenses of, account executives and other
employees of  DWR  and other  Selected  Broker-Dealers, including  overhead  and
telephone  expenses; (2) sales  incentives and bonuses  to sales representatives
and to marketing  personnel in  connection with  promoting sales  of the  Fund's
shares;  (3) expenses incurred in connection  with promoting sales of the Fund's
shares; (4)  preparing  and distributing  sales  literature; and  (5)  providing
advertising  and promotional activities, including  direct mail solicitation and
television, radio, newspaper, magazine and other media advertisements.
 
DETERMINATION OF NET ASSET VALUE
 
The net asset value per share of the Fund is determined once daily at 4:00 p.m.,
New York time, (or,  on days when  the New York Stock  Exchange closes prior  to
4:00  p.m., at such earlier time), on each  day that the New York Stock Exchange
is open by  taking the  value of  all assets of  the Fund,  subtracting all  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.
 
    In  the calculation of the  Fund's net asset value:  (1) an equity portfolio
security listed or traded on  the New York or  American Stock Exchange or  other
domestic  or foreign stock exchange or quoted  by NASDAQ is valued at its latest
sale price on that exchange or quotation  service prior to the time when  assets
are  valued; if  there were no  sales that day,  the security, is  valued at the
latest bid  price  (in  cases where  securities  are  traded on  more  than  one
exchange,  the securities are  valued on the exchange  designated as the primary
market pursuant  to procedures  adopted  by the  Trustees);  and (2)  all  other
portfolio  securities for  which over-the-counter market  quotations are readily
available are valued  at the latest  available bid  price prior to  the time  of
valuation.   When  market  quotations  are   not  readily  available,  including
circumstances under which it is determined  by the Investment Manager that  sale
or  bid  prices  are not  reflective  of  a security's  market  value, portfolio
securities are valued  at their  fair value as  determined in  good faith  under
procedures  established  by  and under  the  general supervision  of  the Fund's
Trustees. For valuation purposes, quotations of foreign portfolio securities are
translated into U.S. dollar equivalents at the prevailing market rates as of the
morning of valuation.  Dividends receivable  are accrued as  of the  ex-dividend
date  or as of  the time that  the relevant ex-dividend  date and amounts become
known.
 
    Short-term debt securities with remaining  maturities of sixty days or  less
at  the  time of  purchase are  valued  at amortized  cost, unless  the Trustees
determine such does  not reflect  the securities'  market value,  in which  case
these  securities  will be  valued  at their  fair  value as  determined  by the
Trustees.
 
    Certain of  the Fund's  portfolio securities  may be  valued by  an  outside
pricing service approved by the Fund's Trustees. The pricing service may utilize
a  matrix  system incorporating  security quality,  maturity  and coupon  as the
evaluation model  parameters,  and/or research  and  evaluations by  its  staff,
including  review of broker-dealer market  price quotations, in determining what
it believes is  the fair valuation  of the portfolio  securities valued by  such
pricing service.
 
                                                                              13
<PAGE>
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  open-end  investment
company  for which InterCapital serves as investment manager (collectively, with
the Fund, the "Dean Witter Funds")) unless the shareholder requests that they be
paid in cash. Such  dividends and distributions  will be paid  in shares of  the
Fund  at net  asset value  per share. At  any time  an investor  may request the
Transfer Agent  in writing  to have  subsequent dividends  and/or capital  gains
distributions  paid  to  the investor  in  cash  rather than  shares.  To assure
sufficient time to process  the change, such request  should be received by  the
Transfer  Agent at least five business days  prior to the payment date for which
it commences to take effect. In the case of recently purchased shares for  which
registration  instructions  have  not been  received  on the  record  date, cash
payments will be made to DWR or other Selected Broker-Dealer through whom shares
were purchased.
 
INVESTMENT OF DISTRIBUTIONS RECEIVED  IN CASH.  Any  shareholder who receives  a
cash  payment representing a  dividend or capital  gains distribution may invest
such dividend  or distribution  at the  net asset  value next  determined  after
receipt  by the  Transfer Agent by  returning the  check or the  proceeds to the
Transfer Agent within 30 days after the payment date.
 
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  Fund's Transfer Agent for  investment in shares of  the
Fund (see "Purchase of Fund Shares" and "Redemptions and
Repurchases--Involuntary Redemption").
 
SYSTEMATIC  WITHDRAWAL  PLAN.   A  systematic withdrawal  plan  (the "Withdrawal
Plan") is available  for shareholders  who own or  purchase shares  of the  Fund
having  a minimum value of $10,000 based  upon the then current net asset value.
The Withdrawal Plan provides  for monthly or  quarterly (March, June,  September
and  December) checks in any  dollar amount, not less than  $25, or in any whole
percentage of the account balance, on an annualized basis.
 
    Shareholders should  contact  their  DWR  or  other  Selected  Broker-Dealer
account executive or the Transfer Agent for further information about any of the
above services.
 
TAX-SHELTERED  RETIREMENT PLANS.  Retirement plans  are available for use by the
self-employed, eligible Individual  Retirement Accounts  and Custodial  Accounts
under  Section 403(b)(7)  of the Internal  Revenue Code. Adoption  of such plans
should be on  advice of legal  counsel or tax  adviser. For further  information
regarding  plan  administration,  custodial fees  and  other  details, investors
should contact their DWR  or other Selected  Broker-Dealer account executive  or
the Transfer Agent.
 
EXCHANGE  PRIVILEGE.    An  "Exchange  Privilege",  that  is,  the  privilege of
exchanging shares of certain  Dean Witter Funds for  shares of the Fund,  exists
whereby  shares  of  various Dean  Witter  Funds which  are  open-end investment
companies sold with either a front-end (at time of purchase) sales charge ("FESC
funds") or a contingent deferred sales charge ("CDSC funds") may be redeemed  at
their  next calculated net asset value and the proceeds of the redemption may be
used to purchase shares of the Fund, Dean Witter Short-Term U.S. Treasury Trust,
Dean Witter Intermediate Term U.S.  Treasury Trust, Dean Witter Balanced  Income
Fund,  Dean Witter Balanced Growth Fund,  and Dean Witter Limited Term Municipal
Trust and shares of five  Dean Witter Funds which  are money market funds:  Dean
Witter  Tax-Free Daily  Income Trust, Dean  Witter U.S.  Government Money Market
Trust, Dean Witter Liquid Asset Fund Inc., Dean Witter California Tax-Free Daily
Income Trust and Dean Witter New York Municipal Money Market Trust (which eleven
funds including  the  Fund  are  hereinafter collectively  referred  to  as  the
"Exchange  Funds"). An exchange from an FESC fund  or a CDSC fund to an Exchange
Fund is on the basis  of the next calculated net  asset value per share of  each
fund  after the exchange order is received.  When exchanging into a money market
fund from an FESC fund or a CDSC fund, shares of the FESC fund or the CDSC  fund
are  redeemed at their next calculated net  asset value and exchanged for shares
of the  money market  fund at  their net  asset value  determined the  following
business day. Subsequently, shares of the Exchange Funds received in an exchange
for shares of an FESC fund (regardless of the type of fund originally purchased)
may be redeemed and exchanged for shares of the other Exchange Funds, FESC funds
or  CDSC  funds (however,  shares of  CDSC funds,  including shares  acquired in
exchange for (i) shares of FESC funds or (ii) shares of the Exchange Funds which
were acquired in exchange  for shares of  FESC funds, may  not be exchanged  for
shares of FESC funds). Additionally, shares of the Exchange Funds received in an
exchange  for shares of a  CDSC fund (regardless of  the type of fund originally
purchased) may be redeemed and exchanged for shares of the other Exchange  Funds
or  CDSC  funds. Ultimately,  any  applicable contingent  deferred  sales charge
("CDSC") will have  to be paid  upon redemption of  shares originally  purchased
from  a CDSC  fund. (If  shares of  the Exchange  Fund received  in exchange for
shares originally purchased from a CDSC fund are exchanged for shares of another
CDSC fund having a different CDSC schedule than that of the CDSC fund from which
the Exchange Fund's  shares were  acquired, the shares  will be  subject to  the
higher CDSC schedule.) During the period of time the shares originally purchased
from  a CDSC fund  remain in an Exchange  Fund (calculated from  the last day of
 
14
<PAGE>
the month in which the Exchange  Fund shares were acquired), the holding  period
(for the purpose of determining the rate of CDSC) is frozen. If those shares are
subsequently  reexchanged  for  shares  of  a  CDSC  fund,  the  holding  period
previously frozen when the first  exchange was made resumes  on the last day  of
the  month in which  shares of the CDSC  fund are reacquired.  Thus, the CDSC is
based upon the period  of time (calculated as  described above) the  shareholder
was invested in a CDSC fund. Exchanges involving FESC funds or CDSC funds may be
made after the shares of the FESC fund or CDSC fund acquired by purchase (not by
exchange  or dividend reinvestment) have been held  for thirty days. There is no
waiting period  for  exchanges  of  shares  acquired  by  exchange  or  dividend
reinvestment.
 
    Purchases  and  exchanges should  be made  for  investment purposes  only. A
pattern of frequent  exchanges may  be deemed by  the Investment  Manager to  be
abusive and contrary to the best interests of the Fund's other shareholders and,
at  the Investment Manager's discretion, may be limited by the Fund's refusal to
accept additional purchases  and/or exchanges  from the  investor. Although  the
Fund  does not  have any  specific definition of  what constitutes  a pattern of
frequent exchanges,  and  will  consider all  relevant  factors  in  determining
whether  a particular situation is abusive and contrary to the best interests of
the Fund and its other shareholders, investors should be aware that the Fund and
each of the other Dean Witter Funds  may in their discretion limit or  otherwise
restrict  the number of  times this Exchange  Privilege may be  exercised by any
investor. Any such restriction will be made  by the Fund on a prospective  basis
only,  upon notice  to the  shareholder not later  than ten  days following such
shareholder's most recent exchange.
 
    The current prospectus for each  fund describes its investment  objective(s)
and  policies, and shareholders  should obtain one and  read it carefully before
investing. Exchanges are subject to  the minimum investment requirement and  any
other  conditions imposed by each fund. An  exchange will be treated for federal
income tax purposes the same  as a repurchase or  redemption of shares on  which
the  shareholder has realized  a capital gain  or loss. However,  the ability to
deduct capital losses on an exchange may be limited in situations where there is
an exchange of  shares within ninety  days after the  shares are purchased.  The
Exchange  Privilege is only available in states where an exchange may legally be
made.
 
    If DWR or another Selected Broker-Dealer is the current dealer of record and
its account  numbers  are part  of  the account  information,  shareholders  may
initiate  an exchange of shares of the Fund  for shares of any of the above Dean
Witter Funds (for which  the Exchange Privilege is  available) pursuant to  this
Exchange  Privilege by  contacting their  DWR or  other Selected  Dealer account
executive  (no  Exchange  Privilege  Authorization  Form  is  required).   Other
shareholders  (and those who are clients  of DWR or other 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 Fund, 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  has
previously  filed an Exchange Privilege Authorization  Form and who is unable to
reach the Fund  by telephone should  contact his  or her DWR  or other  Selected
Broker-Dealer  account  executive, if  appropriate, or  make a  written exchange
request. Shareholders are  advised that  during periods of  drastic economic  or
market  changes, it  is possible that  the telephone exchange  procedures may be
difficult to implement, although this has  not been the experience of the  other
Dean Witter Funds in the past.
 
    Additional  information on the above is  available from an account executive
of DWR or another Selected Broker-Dealer or from the Transfer Agent.
 
REDEMPTIONS AND REPURCHASES
- --------------------------------------------------------------------------------
 
REDEMPTION.  Shares  of the Fund  can be redeemed  for cash at  any time at  its
respective  current net asset  value per share (without  any redemption or other
charge). If  shares  are  held  in  a  shareholder's  account  without  a  share
certificate,  a written request for redemption  is required. If certificates are
held by  the  shareholder,  the  shares may  be  redeemed  by  surrendering  the
certificates with a written request for redemption. 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 at P.O  Box 983, Jersey City, NJ 07303, which  will
redeem  the shares at  their net asset  value next determined  (see "Purchase of
Fund Shares--Determination of Net Asset Value") after it
 
                                                                              15
<PAGE>
receives the request, and  certificates, if any, in  good order. Any  redemption
request  received after  such determination will  be redeemed at  the price next
determined. The term "good order" means that the share certificates, 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  will be  accepted. A  stock power  may be  obtained from  any dealer or
commercial bank. The Fund may  change the signature guarantee requirements  upon
notice to shareholders, which may be by means of a new Prospectus.
 
    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  for the  account of  the  shareholder), partnership,  trust or
fiduciary, or sent to  the shareholder at an  address other than the  registered
address,  signature(s) must be guaranteed by an eligible guarantor acceptable to
the Transfer  Agent  (shareholders  should  contact the  Transfer  Agent  for  a
determination as to whether a particular institution is an eligible guarantor).
 
REPURCHASE.   DWR and other Selected Broker-Dealers are authorized to repurchase
shares represented by  a share certificate  which is delivered  to any of  their
offices.  Shares held in a shareholder's account without a share certificate may
also be repurchased by DWR and other Selected Broker-Dealers upon the telephonic
request of the  shareholder. The repurchase  price is the  net asset value  next
determined  (see "Purchase  of Fund  Shares--Determination of  Net Asset Value")
after such repurchase order is received by DWR or other Selected  Broker-Dealer.
Payment  for shares repurchased may  be made by the  Fund to the Distributor for
the  account  of  the  shareholder.  The   offer  by  DWR  and  other   Selected
Broker-Dealers  to repurchase shares from  shareholders 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. If the  shares to  be redeemed  have recently  been purchased  by
check,  payment of the redemption  proceeds may be delayed  for the minimum time
needed to verify that the check used  for investment has been honored (not  more
than  fifteen days from the time of receipt of the check by the Transfer Agent).
Shareholders  maintaining  margin   accounts  with  DWR   or  another   Selected
Broker-Dealer  are referred to their account executive regarding restrictions on
redemption of shares of the Fund pledged in the margin account.
 
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  net asset value  next determined  after a reinstatement
request, together with the proceeds, is received by the Transfer Agent.
 
INVOLUNTARY REDEMPTION.   The Fund  reserves the right  to redeem,  on 60  days'
notice  and  at  net asset  value,  the shares  (other  than shares  held  in an
Individual Retirement Account  or custodial account  under Section 403(b)(7)  of
the  Internal Revenue Code) of any shareholder whose shares have a value of less
than $100 as a result  of redemptions or repurchases,  or such lesser amount  as
may  be fixed  by the  Trustees or,  in the  case of  an account  opened through
EasyInvest-SM-, if after twelve  months the shareholder  has invested less  than
$1,000  in the account. However,  before the Fund redeems  such shares and sends
the proceeds to the shareholder, it  will notify the shareholder that the  value
of the shares is less than the applicable amount and allow the shareholder sixty
days  in which to make an additional investment in an amount which will increase
the value of his or her account to at least the applicable amount or more before
the redemption is processed.
 
DIVIDENDS, DISTRIBUTIONS AND TAXES
- --------------------------------------------------------------------------------
 
DIVIDENDS AND DISTRIBUTIONS.   The Fund declares dividends  on each day the  New
York  Stock Exchange is  open for business. Such  dividends are payable monthly.
The Fund intends  to distribute substantially  all of its  daily net  investment
income  on an annual  basis. Dividends from  net capital gains,  if any, will be
paid at least once each year.
 
    Shareholders may  instruct the  Transfer Agent  (in writing)  to have  their
dividends  paid  out  monthly  in cash.  Processing  of  dividend  checks begins
immediately following the monthly payment date. Shareholders who have  requested
to  receive dividends in cash will normally be sent their monthly dividend check
during the first ten days of the following month.
 
TAXES.  Because the Fund intends to distribute all of its net investment  income
and  net short-term capital gains to shareholders and otherwise remain qualified
as a regulated  investment company under  Subchapter M of  the Internal  Revenue
Code, it is not expected that the Fund will be
 
16
<PAGE>
required to pay any federal income tax on such income and capital gains.
 
    Shareholders  who are  required to pay  taxes on their  income 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  and  net  short-term  capital  gains,  are  taxable  to  the
shareholder as ordinary  dividend income regardless  of whether the  shareholder
receives  such  distributions in  additional shares  or  in cash.  Any dividends
declared in  the  last quarter  of  any calendar  year  which are  paid  in  the
following  year prior to  February 1 will  be deemed, for  tax purposes, to have
been received by the shareholder in the prior year.
 
    Distributions of  net  long-term  capital  gains, if  any,  are  taxable  to
shareholders as long-term capital gains regardless of how long a shareholder has
held the Fund's shares and regardless of whether the distribution is received in
additional   shares   or   in   cash.   It   is   not   anticipated   that   any
portion of the Fund's distributions will be eligible for the dividends  received
deduction to corporate shareholders.
 
    After  the  end  of  the  calendar  year,  shareholders  will  be  sent full
information on their dividends and capital gains distributions for tax purposes,
including information  as to  the portion  taxable as  ordinary income  and  the
portion taxable as long-term capital gains.
 
    To  avoid being subject to  a 31% federal backup  withholding tax on taxable
dividends, capital  gains  distributions and  the  proceeds of  redemptions  and
repurchases, shareholders' taxpayer identification numbers must be furnished and
certified  as to their accuracy. Shareholders  who are not citizens or residents
of, or entities organized  in, the United States  may be subject to  withholding
taxes of up to 30% on certain payments received from the Fund.
 
    The   foregoing  discussion  relates  solely   to  the  federal  income  tax
consequences of an investment in the Fund. Distributions may also be subject  to
state  and local taxes; therefore, each shareholder is advised to consult his or
her own tax adviser.
 
PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------
 
From time to time the  Fund may quote its "yield"  and/or its "total return"  in
advertisements  and sales literature. Both the yield and the total return of the
Fund are based on  historical earnings and are  not intended to indicate  future
performance.  The yield of the  Fund is computed by  dividing the net investment
income of the Fund over a 30-day  period by an average value (using the  average
number of shares entitled to receive dividends and the net asset value per share
at  the  end  of  the  period), all  in  accordance  with  applicable regulatory
requirements. Such amount is compounded for six months and then annualized for a
twelve-month period to derive the yield of the Fund.
 
    From time to time  the Fund may quote  its "total return" in  advertisements
and  sales  literature. The  total return  of  the Fund  is based  on historical
earnings and is not intended to indicate future performance. The "average annual
total return" of the Fund refers  to a figure reflecting the average  annualized
percentage  increase (or decrease) in the value  of an initial investment in the
Fund of $1,000 over periods of one, five  and ten years or over the life of  the
Fund,  if less than any  of the foregoing. Average  annual total return reflects
all income earned by  the Fund, any appreciation  or depreciation of the  Fund's
assets,  all expenses incurred by the Fund  and any sales charges which would be
incurred by redeeming shareholders, for the period. 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, and year-by-year or
other types of total return figures. The  Fund may also advertise the growth  of
hypothetical investments of $10,000, $50,000 and $100,000 in shares of the Fund.
The  Fund  from time  to time  may  also advertise  its performance  relative to
certain performance rankings and  indexes compiled by independent  organizations
(such as 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. There are  no
conversion,   pre-emptive  or  other  subscription   rights.  In  the  event  of
liquidation, each share of  beneficial interest of the  Fund is entitled to  its
portion of all of the Fund's assets after all debts and expenses have been paid.
The shares do not have cumulative voting rights.
 
    The  Fund is  not required  to hold Annual  Meetings of  Shareholders and in
ordinary circumstances  the Fund  does not  intend to  hold such  meetings.  The
Trustees  may call  Special Meetings of  Shareholders for  action by shareholder
vote as may be required  by the Act or the  Declaration of Trust. Under  certain
circumstances  the Trustees may be  removed by action of  the Trustees or by the
shareholders.
 
                                                                              17
<PAGE>
    Under Massachusetts law, shareholders of a business trust may, under certain
circumstances, be  held personally  liable as  partners for  obligations of  the
Fund.  However,  the  Declaration of  Trust  contains an  express  disclaimer of
shareholder liability for acts  or obligations of the  Fund, requires that  Fund
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, in the opinion of Massachusetts
counsel to the Fund, the risk to shareholders of personal liability is remote.
 
CODE OF ETHICS.  Directors, officers and employees of InterCapital, Dean  Witter
Services Company Inc. and the Distributor are subject to a strict Code of Ethics
adopted  by those companies. The  Code of Ethics is  intended to ensure that the
interests of shareholders  and other clients  are placed ahead  of any  personal
interest,  that no undue personal benefit is obtained from a person's employment
activities and that actual and potential  conflicts of interest are avoided.  To
achieve  these goals and comply with regulatory requirements, the Code of Ethics
requires, among other things, that personal securities transactions by employees
of the companies be subject to an  advance clearance process to monitor that  no
Dean  Witter Fund is engaged at the same time  in a purchase or sale of the same
security. The  Code of  Ethics bans  the purchase  of securities  in an  initial
public  offering, and also prohibits engaging in futures and option 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.
