              PROSPECTUS
   
              JUNE 16, 1997
    
 
              Dean Witter High Income Securities (the "Fund") is an open-end
diversified management investment company whose primary investment objective is
to earn a high level of current income. As a secondary objective, the Fund will
seek capital appreciation, but only when consistent with its primary objective.
The Fund seeks high current income by investing principally in fixed-income
securities which are rated in the lower categories by established rating
services (Ba or lower by Moody's Investors Service, Inc. or BB or lower by
Standard & Poor's Corporation) or are non-rated securities of comparable
quality.
 
               THE FUND INVESTS PREDOMINANTLY IN LOWER-RATED FIXED-INCOME
SECURITIES COMMONLY KNOWN AS JUNK BONDS AND INVESTORS SHOULD CAREFULLY CONSIDER
THE RISKS THEY PRESENT, INCLUDING THE RISK OF DEFAULT. BONDS OF THIS TYPE ARE
SUBJECT TO GREATER RISKS THAN HIGHER-RATED SECURITIES AND ARE CONSIDERED TO BE
SPECULATIVE WITH REGARD TO THE PAYMENT OF INTEREST AND RETURN OF PRINCIPAL.
INVESTORS SHOULD ALSO BE COGNIZANT OF THE FACT THAT SUCH SECURITIES ARE NOT
GENERALLY MEANT FOR SHORT-TERM INVESTING AND SHOULD ASSESS THE RISKS ASSOCIATED
WITH AN INVESTMENT IN THE FUND. (SEE "RISK CONSIDERATIONS.")
 
               Shares of the Fund are continuously offered at net asset value.
However, redemptions and/or repurchases are subject in most cases to a
contingent deferred sales charge, scaled down from 4% to 1% of the amount
redeemed, if made within five 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 Rule 12b-1 Plan of Distribution at
the annual rate of 0.80% of the lesser of the (i) average daily aggregate net
sales or (ii) average daily net assets of the Fund. (See "Purchase 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
Fund              open-end diversified management investment company investing principally in lower-rated fixed- income
                  securities (see page 5).
- ----------------------------------------------------------------------------------------------------------------------
Shares Offered    Shares of beneficial interest with $0.01 par value (see page 23).
- ----------------------------------------------------------------------------------------------------------------------
Offering          At net asset value without sales charge (see page 14). Shares redeemed within five years of purchase
Price             are subject to a contingent deferred sales charge under most circumstances (see page 20).
- ----------------------------------------------------------------------------------------------------------------------
Minimum Purchase  Minimum initial investment, $1,000 ($100 if the account is opened through EasyInvest-SM-); minimum
                  subsequent investment, $100 (see page 14).
- ----------------------------------------------------------------------------------------------------------------------
Investment        A high level of current income primarily; capital appreciation is secondary (see page 5).
Objective
- ----------------------------------------------------------------------------------------------------------------------
Investment        Dean Witter InterCapital Inc., the Investment Manager of the Fund, and its wholly-owned subsidiary,
Manager           Dean Witter Services Company Inc., serve in various investment management, advisory, management and
                  administrative capacities to 100 investment companies and other portfolios with assets of
                  approximately $95.6 billion at May 31, 1997 (see page 5).
- ----------------------------------------------------------------------------------------------------------------------
Management Fee    The Investment Manager receives a monthly fee at the annual rate of 0.50% of average daily net
                  assets. 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 (see page 5).
- ----------------------------------------------------------------------------------------------------------------------
Dividends and     Income dividends are declared and paid monthly; capital gains, if any, may be distributed at least
Capital Gains     annually. Dividends and distributions are automatically reinvested in additional shares at net asset
Distributions     value (without sales charge), unless the shareholder elects to receive cash (see page 22).
- ----------------------------------------------------------------------------------------------------------------------
Distributor and   Dean Witter Distributors Inc. (the "Distributor"). The Distributor receives from the Fund, pursuant
Distribution Fee  to a Rule 12b-1 Plan of Distribution, a distribution fee accrued daily and payable monthly at the
                  rate of 0.80% 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 15 and 20).
- ----------------------------------------------------------------------------------------------------------------------
Redemption--      Shares are redeemable by the shareholder at net asset value. An account may be involuntarily
Contingent        redeemed if total value of the account is less than $100 or, if the account was opened through
Deferred Sales    EasyInvest-SM-, if after twelve months the shareholder has invested less than $1,000 in the account.
Charge            Although no commission or sales charge is imposed upon the purchase of shares, a contingent deferred
                  sales charge (scaled down from 4% to 1%) is imposed on any redemption of shares if after such
                  redemption the aggregate current value of an account with the Fund falls below the aggregate amount
                  of the investor's purchase payments made during the five years preceding the redemption. However,
                  there is no charge imposed on redemption of shares purchased through reinvestment of dividends or
                  distributions (see pages 20-21).
- ----------------------------------------------------------------------------------------------------------------------
Risks             Compared with higher rated, lower yielding fixed-income securities, portfolio securities of the Fund
                  may be subject to greater risk of loss of income and principal and greater risk of increases and
                  decreases in net asset value due to market fluctuations. The Fund may also purchase when-issued and
                  delayed delivery, when, as and if issued securities, restricted securities, and zero coupon
                  securities, rights and warrants, convertible securities, foreign securities, common stock and
                  adjustable rate mortgages and enter into repurchase agreements, reverse repurchase agreements and
                  dollar rolls, options and futures transactions and forward foreign currency exchange contracts, all
                  of which involve certain special risks. Investors should review the investment objectives and
                  policies of the Fund carefully and consider their ability to assume the risks involved in purchasing
                  shares of the Fund (see pages 6-13).

THE FUND AND ITS MANAGEMENT
- --------------------------------------------------------------------------------
 
    Dean  Witter High Income Securities (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  The
Commonwealth of Massachusetts on March 23, 1994.
 
   
    Dean  Witter InterCapital Inc. ("InterCapital" or the "Investment Manager"),
whose address is Two World Trade Center, New York, New York 10048, is the Fund's
Investment Manager.  The Investment  Manager, which  was incorporated  in  July,
1992,  is a wholly-owned  subsidiary of Morgan Stanley,  Dean Witter, Discover &
Co. ("MSDWD"),  a  preeminent  global financial  services  firm  that  maintains
leading  market positions in  each of its  three primary businesses--securities,
asset management and credit services.
    
 
   
    InterCapital and its wholly-owned  subsidiary, Dean Witter Services  Company
Inc.,   serve  in  various  investment   management,  advisory,  management  and
administrative capacities to 100 investment companies (the "Dean Witter Funds"),
thirty of which are listed on the New York Stock Exchange, with combined  assets
of  approximately $92.3  billion at  May 31,  1997. The  Investment Manager also
manages portfolios of  pension plans, other  institutions and individuals  which
aggregated approximately $3.3 billion at such date.
    
 
    The  Fund  has retained  the  Investment Manager  to  provide administrative
services, manage its business  affairs and manage the  investment of the  Fund's
assets,  including the placing of orders for  the purchase and sale of portfolio
securities. InterCapital  has  retained Dean  Witter  Services Company  Inc.  to
perform  the  aforementioned administrative  services for  the Fund.  The Fund's
Board of  Trustees  reviews  the  various services  provided  by  or  under  the
direction of the Investment Manager to ensure that the Fund's general investment
policies  and programs  are being properly  carried out  and that administrative
services are being provided to the Fund in a satisfactory manner.
 
   
    As full compensation for the services  and facilities furnished to the  Fund
and  for expenses of the  Fund assumed by the  Investment Manager, the Fund pays
the Investment Manager  monthly compensation  calculated daily  by applying  the
annual rate of 0.50% to the Fund's net assets determined as of the close of each
business  day. For the fiscal year ended  March 31, 1997, the Fund accrued total
compensation to the Investment Manager amounting  to an annual rate of 0.47%  of
the Fund's average daily net assets and the Fund's total expenses amounted to an
annual rate of 1.39% of the Fund's average daily net assets.
    
 
INVESTMENT OBJECTIVES AND POLICIES
- --------------------------------------------------------------------------------
 
    The  primary investment  objective of the  Fund is  to earn a  high level of
current  income.  As  a  secondary   objective,  the  Fund  will  seek   capital
appreciation,  but  only when  consistent  with its  primary  objective. Capital
appreciation may result, for example, from an improvement in the credit standing
of an issuer whose securities are held in the Fund's portfolio or from a general
decline in  interest  rates,  or  a combination  of  both.  Conversely,  capital
depreciation  may  result, for  example,  from a  lowered  credit standing  or a
general rise in interest rates, or a combination of both. There is no  assurance
that the objectives will be achieved. The objectives are fundamental policies of
the Fund and may not be changed without the approval of the Fund's shareholders.
The   following  policies  may  be  changed  by  the  Fund's  Trustees,  without
shareholder approval.
 
    The  higher  yields  sought  by  the  Fund  are  generally  obtainable  from
securities rated in the lower categories by recognized rating services. The Fund
seeks high current income by investing principally
 
                                       5
<PAGE>
(at  least 65% of its total assets) in fixed-income securities rated Ba or lower
by Moody's Investors  Service, Inc. ("Moody's"),  or BB or  lower by Standard  &
Poor's Corporation ("Standard & Poor's"). Fixed-income securities rated Ba or BB
or  lower by Moody's and  Standard & Poor's, respectively,  are considered to be
speculative investments. Furthermore, the Fund does not have any minimum quality
rating standard for its investments. As such, the Fund may invest in  securities
rated  as low as Caa,  Ca or C by Moody's  or CCC, CC, C, CI  or D by Standard &
Poor's. Fixed-income securities  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 (the  Fund may purchase securities
which are  in  default and  which,  thereby,  are not  paying  its  fixed-income
security holders principal and/or interest). Bonds rated D by Standard & Poor's,
their  lowest bond rating, are  in payment default. For  a further discussion of
the characteristics and risks associated  with high yield securities, see  "Risk
Considerations"  below. A description of corporate  bond ratings is contained in
the Appendix.
 
    Non-rated securities will also be considered for investment by the Fund when
the Investment Manager believes that the  financial condition of the issuers  of
such  securities,  or the  protection afforded  by the  terms of  the securities
themselves, makes  them  appropriate  investments for  the  Fund.  Under  normal
circumstances, the dollar-weighted average maturity of the Fund's portfolio will
be between five and ten years.
 
    Up  to  35% of  the Fund's  total  assets may,  under normal  conditions, be
invested in  common  stocks;  fixed-income securities  convertible  into  common
stocks;  warrants  to  purchase  common  stocks;  investment  grade fixed-income
securities; U.S.  Government  securities  (including  zero  coupon  securities);
mortgage-backed  securities,  financial futures  contracts and  options thereon;
index options;  options  on  debt and  equity  securities;  private  placements;
repurchase  agreements; and reverse  repurchase agreements. In  addition, any or
all of the  above 35% of  total assets portion  of the Fund's  portfolio may  be
comprised of securities issued by foreign issuers.
 
    Pending investment of proceeds from the sale of shares of the Fund or of its
portfolio  securities or  at other times  when market conditions  dictate a more
"defensive" investment  strategy, the  Fund may  invest without  limit in  money
market  instruments, including commercial paper  of corporations organized under
the  laws  of  any  state  or  political  subdivision  of  the  United   States,
certificates  of deposit, bankers' acceptances and other obligations of domestic
banks or domestic  branches of foreign  banks, or foreign  branches of  domestic
banks,  in  each  case  having  total  assets  of  at  least  $500  million, and
obligations issued or  guaranteed by  the United States  Government, or  foreign
governments  or  their respective  instrumentalities or  agencies. The  yield on
these securities  will  generally tend  to  be lower  than  the yield  on  other
securities  to  be purchased  by  the Fund.  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 economic developments which might adversely affect the payment
of principal or interest.
 
    All fixed-income securities are  subject to two types  of risks: the  credit
risk  and the interest rate risk. The credit  risk relates to the ability of the
issuer to  meet  interest  or principal  payments  or  both as  they  come  due.
Generally,  higher yielding  bonds are  subject to  a credit  risk to  a greater
extent than  higher  quality  bonds.  The  interest  rate  risk  refers  to  the
fluctuations  in net  asset value  of any  portfolio of  fixed-income securities
resulting solely  from  the inverse  relationship  between price  and  yield  of
fixed-income  securities;  that is,  when the  general  level of  interest rates
rises, the prices of outstanding
 
                                       6
<PAGE>
   
fixed-income securities generally decline, and when interest rates fall,  prices
generally rise. The Fund's yield will also vary based on the yield of the Fund's
portfolio securities.
    
 
    The  ratings of fixed-income securities by Moody's and Standard & Poor's are
a generally accepted barometer of credit risk. However, as the  creditworthiness
of  issuers of  lower-rated fixed-income  securities is  more problematical than
that of issuers of higher-rated fixed-income securities, the achievement of  the
Fund's  investment  objectives  will  be  more  dependent  upon  the  Investment
Manager's own  credit  analysis  than would  be  the  case with  a  mutual  fund
investing primarily in higher quality bonds. The Investment Manager will utilize
a   security's  credit   rating  as  simply   one  indication   of  an  issuer's
creditworthiness and will principally rely upon its own analysis of any security
currently held  by the  Fund or  potentially  purchasable by  the Fund  for  its
portfolio.
 
    In determining which securities to purchase or hold for the Fund's portfolio
and  in seeking to reduce credit and interest rate risks, the Investment Manager
will rely on  information from  various sources,  including: the  rating of  the
security;  research, analysis and  appraisals of brokers  and dealers, including
DWR; the views of the Fund's Trustees and others regarding economic developments
and interest rate trends; and the  Investment Manager's own analysis of  factors
it  deems relevant. The extent to which  the Investment Manager is successful in
reducing depreciation  or losses  arising from  either interest  rate or  credit
risks  depends in part  on the Investment  Manager's portfolio management skills
and judgment in  evaluating the factors  affecting the value  of securities.  No
assurance can be given regarding the degree of success that will be achieved.
 
RISK CONSIDERATIONS
 
    Because  of  the special  nature  of the  Fund's  investment in  high income
securities, commonly  known as  junk  bonds, the  Investment Manager  must  take
account of certain special considerations in assessing the risks associated with
such  investments. Although the  growth of the high  income securities market in
the 1980s had paralleled a long  economic expansion, recently many issuers  have
been affected by adverse economic and market conditions. It should be recognized
that  an economic  downturn or increase  in interest  rates is likely  to have a
negative effect on  the high income  bond market and  on the value  of the  high
income 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 high income 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  corporate
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  high  income  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  and  payment-in-kind 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 high income 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
 
                                       7
<PAGE>
arrive at a fair value for certain  high income securities at certain times  and
could  make it difficult for  the Fund to sell  certain securities. In addition,
new laws and proposed new laws may have an adverse effect upon the value of high
income securities and a concomitant negative impact upon the net asset value  of
a share of the Fund.
 
   
    During  the fiscal  year ended March  31, 1997, the  monthly dollar weighted
average ratings  of  the debt  obligations  held by  the  Fund, expressed  as  a
percentage of the Fund's total investments, were as follows:

</TABLE>
    
 
    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 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, including  the  risks  of  default or
bankruptcy of the selling financial institution, the Fund follows procedures  to
minimize  such risks. These procedures include effecting repurchase transactions
only with large,  well-capitalized and  well-established financial  institutions
and maintaining adequate collateralization.
 
    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 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. An  increase  in the
percentage of the  Fund's assets committed  to the purchase  of securities on  a
when-issued,  delayed  delivery or  forward  commitment basis  may  increase the
volatility of the Fund's net asset value.
 
    WHEN, AS AND IF ISSUED  SECURITIES.  The Fund  may purchase securities on  a
"when,  as and if issued" basis under which the issuance of the security depends
upon the  occurrence  of a  subsequent  event, such  as  approval of  a  merger,
corporate  reorganization,  leveraged  buyout  or  debt  restructuring.  If  the
anticipated event does  not occur and  the securities are  not issued, the  Fund
will  have lost  an investment  opportunity. There  is no  overall limit  on the
percentage of  the Fund's  assets which  may  be committed  to the  purchase  of
securities on a "when, as and if issued" basis. An increase in the percentage of
the  Fund's assets committed to the purchase of securities on a "when, as and if
issued" basis may increase the volatility of its net asset value.
 
    PRIVATE PLACEMENTS.  The Fund  may invest up to 10%  of its total assets  in
securities  which  are  subject  to restrictions  on  resale  because  they have
 
                                       8
<PAGE>
not  been  registered  under  the  Securities  Act  of  1933,  as  amended  (the
"Securities  Act"), or which  are otherwise not  readily marketable. (Securities
eligible for  resale  pursuant  to  Rule 144A  under  the  Securities  Act,  and
determined  to be liquid  pursuant to the procedures  discussed in the following
paragraph, are not subject to  the foregoing restriction.) These securities  are
generally   referred  to   as  private  placements   or  restricted  securities.
Limitations on the resale of such securities may have an adverse effect on their
marketability, and  may prevent  the Fund  from disposing  of them  promptly  at
reasonable  prices. The Fund  may have to  bear the expense  of registering such
securities for  resale and  the risk  of substantial  delays in  effecting  such
registration.
 
    The  Securities  and Exchange  Commission has  adopted  Rule 144A  under the
Securities Act,  which  permits  the  Fund  to  sell  restricted  securities  to
qualified  institutional  buyers  without  limitation.  The  Investment Manager,
pursuant to  procedures  adopted  by the  Trustees  of  the Fund,  will  make  a
determination  as to the liquidity of  each restricted security purchased by the
Fund. If a restricted security is determined to be "liquid", such security  will
not  be included within the category  "illiquid securities", which under current
policy may not exceed 15% of the  Fund's net assets. However, investing in  Rule
144A  Securities  could  have  the  effect  of  increasing  the  level  of  Fund
illiquidity to the extent the Fund, at a particular point in time, may be unable
to find qualified institutional buyers interested in purchasing such securities.
 
    REVERSE REPURCHASE  AGREEMENTS AND  DOLLAR ROLLS.   The  Fund may  also  use
reverse  repurchase  agreements  and  dollar rolls  as  part  of  its investment
strategy. Reverse repurchase agreements involve  sales by the Fund of  portfolio
assets  concurrently with an agreement by the Fund to repurchase the same assets
at a later date at a fixed price. The Fund may enter into dollar rolls in  which
the   Fund  sells   securities  and   simultaneously  contracts   to  repurchase
substantially similar (same type  and coupon) securities  on a specified  future
date.  Reverse repurchase agreements and dollar  rolls involve the risk that the
market value of  the securities the  Fund is obligated  to repurchase under  the
agreement  may decline  below the  repurchase price. In  the event  the buyer of
securities under  a  reverse  repurchase  agreement or  dollar  roll  files  for
bankruptcy or becomes insolvent, the Fund's use of proceeds of the agreement may
be  restricted pending  a determination  by the other  party, or  its trustee or
receiver, whether to enforce the Fund's obligation to repurchase the securities.
Reverse repurchase  agreements  and  dollar  rolls  are  speculative  techniques
involving leverage, and are considered borrowings by the Fund.
 
    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.
 
    INVESTMENT IN REAL  ESTATE INVESTMENT TRUSTS.  The Fund may  invest in  real
estate investment trusts,
 
                                       9
<PAGE>
which  pool investors' funds for investments primarily in commercial real estate
properties. 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 a real estate investment trust,  the Fund would bear its ratable
share of the real estate investment trust'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 stockholders  in effect  will be  absorbing duplicate  levels of  fees  with
respect to investments in real estate investment trusts.
 
    RIGHTS  AND WARRANTS.  The Fund may acquire rights and/or warrants which are
attached to  other  securities  in its  portfolio,  or  which are  issued  as  a
distribution  by the issuer of  a security held in  its portfolio. Rights and/or
warrants are, in  effect, options to  purchase equity securities  at a  specific
price, generally valid for a specific period of time, and have no voting rights,
pay  no dividends  and have  no rights with  respect to  the corporation issuing
them.
 
    CONVERTIBLE SECURITIES.  Among the fixed-income securities in which the Fund
may invest  are "convertible"  securities.  A convertible  security is  a  bond,
debenture, note, preferred stock or other security that may be converted into or
exchanged  for a prescribed  amount of common  stock of the  same or a different
issuer within  a particular  period of  time at  a specified  price or  formula.
Convertible  securities rank senior to common  stocks in a corporation's capital
structure and, therefore, entail less risk than the corporation's common  stock.
The value of a convertible security is a function of its "investment value" (its
value  as if it did not have a conversion privilege), and its "conversion value"
(the security's worth if it were to be exchanged for the underlying security, at
market value, pursuant to its conversion privilege). Fluctuations in the  prices
of  an  underlying  security  will  affect  the  conversion  value  and  cause a
concomitant fluctuation in the price of the convertible security.
 
    To the extent that a convertible security's investment value is greater than
its conversion  value,  its  price  will  be  primarily  a  reflection  of  such
investment  value and its price  will be likely to  increase when interest rates
fall and decrease when interest rates rise, as with a fixed-income security (the
credit standing of the issuer and other  factors may also have an effect on  the
convertible  security's value). If  the conversion value  exceeds the investment
value, the price  of the  convertible security  will rise  above its  investment
value  and, in addition,  will sell at  some premium over  its conversion value.
(This premium  represents  the  price  investors are  willing  to  pay  for  the
privilege  of purchasing a  fixed-income security with  a possibility of capital
appreciation due to the  conversion privilege.) At such  times the price of  the
convertible  security  will tend  to fluctuate  directly with  the price  of the
underlying equity security.
 
    Because of the special nature of  the Fund's permitted investments in  lower
rated  convertible  securities,  the  Investment Manager  must  take  account of
certain special  considerations  in assessing  the  risks associated  with  such
investments.  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
corporate  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 lower rated convertible 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 corresponding volatility in the  net asset value of a share  of
the Fund.
 
                                       10
<PAGE>
    FOREIGN SECURITIES.  The Fund may invest in securities of foreign companies.
Foreign  securities investments may be affected  by changes in currency rates or
exchange control regulations, change in governmental administration or  economic
or monetary policy (in the United States and abroad) or changed circumstances in
dealings  between nations. Costs will be incurred in connection with conversions
between various currencies held by  the Fund. 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.
 
    FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS. The Fund may enter into forward
foreign  currency exchange  contracts ("forward  contracts") as  a hedge against
fluctuations in future foreign exchange rates. The Fund will conduct its foreign
currency exchange transactions either on a  spot (i.e., cash) basis at the  spot
rate  prevailing in  the foreign currency  exchange market,  or through entering
into forward  contracts  to  purchase  or sell  foreign  currencies.  A  forward
contract  involves an obligation  to purchase or  sell a specific  currency at a
future date, which may be any fixed number of days from the date of the contract
agreed upon by the parties, at a price  set at the time of the contract.  Should
forward  prices decline  during the  period between  the Fund's  entering into a
forward contract for the sale of a foreign currency and the date it enters  into
an  offsetting contract for the purchase of  the foreign currency, the Fund will
realize a gain to  the extent the price  of the currency it  has agreed to  sell
exceeds  the price  of the  currency it has  agreed to  purchase. Should forward
prices increase, the  Fund will suffer  a loss to  the extent the  price of  the
currency  it has  agreed to purchase  exceeds the  price of the  currency it has
agreed to sell.
 
    COMMON STOCKS.   The Fund may  directly purchase common  stocks on the  open
market.  In addition, the Fund may acquire  common stocks when they are included
in a unit with fixed-income securities purchased by the Fund; when  fixed-income
securities  held  by the  Fund are  converted  to equity  issues; when  the Fund
exercises a warrant; and when the  Fund purchases the common stock of  companies
involved in takeovers or recapitalization, where the issuer or a stockholder has
offered,   or  pursuant  to  a  "going  private"  transaction  is  effecting,  a
transaction involving the  issuance of newly  issued fixed-income securities  to
the holders of such common stock.
 
    The  prices  of  common stock  are  generally  more volatile  than  those of
fixed-income securities. Moreover, not all common stock pay dividends and  those
that  do generally pay lower amounts than most fixed-income securities. The Fund
will only purchase common stocks  directly when the Investment Manager  believes
that their purchase will assist the Fund in meeting its investment objectives.
 
    ADJUSTABLE RATE MORTGAGE SECURITIES.  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
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
 
                                       11
<PAGE>
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.
 
   
OPTIONS AND FUTURES TRANSACTIONS
    
 
    The  Fund may purchase  and sell (write)  call and put  options on portfolio
securities which are denominated  in either U.S.  dollars or foreign  currencies
and on the U.S. dollar and foreign currencies, which are or may in the future be
listed  on  several U.S.  and  foreign securities  exchanges  or are  written in
over-the-counter transactions ("OTC options"). OTC options are purchased from or
sold (written)  to dealers  or financial  institutions which  have entered  into
direct agreements with the Fund.
 
    The  Fund is permitted to write covered call options on portfolio securities
and the U.S.  dollar and foreign  currencies, without limit,  in order to  hedge
against  the  decline in  the  value of  a security  or  currency in  which such
security is denominated, to  earn additional income and  to close out long  call
option  positions. The Fund may write covered  put options, under which the Fund
incurs an obligation  to buy the  security (or currency)  underlying the  option
from  the purchaser of the put at the option's exercise price at any time during
the option period, at the purchaser's election.
 
    The Fund  may  purchase listed  and  OTC call  and  put options  in  amounts
equalling  up to 5% of  its total assets. The Fund  may purchase call options to
close out a covered call position or to protect against an increase in the price
of a security it  anticipates purchasing or,  in the case of  call options on  a
foreign  currency,  to hedge  against  an adverse  exchange  rate change  of the
currency  in  which  the  security  it  anticipates  purchasing  is  denominated
vis-a-vis  the currency in which the exercise price is denominated. The Fund may
purchase put options on  securities which it holds  in its portfolio to  protect
itself  against a decline in the value of  the security and to close out written
put positions in a manner similar to call option closing purchase  transactions.
There  are  no other  limits  on the  Fund's ability  to  purchase call  and put
options.
 
    The Fund may purchase and sell futures contracts that are currently  traded,
or  may in  the future  be traded,  on U.S.  and foreign  commodity exchanges on
underlying portfolio securities, on any  currency ("currency" futures), on  U.S.
and  foreign  fixed-income  securities  ("interest rate"  futures)  and  on such
indexes of U.S.  or foreign equity  or fixed-income securities  as may exist  or
come  into being ("index" futures). The Fund  may purchase or sell interest rate
futures contracts for the  purpose of hedging  some or all of  the value of  its
portfolio  securities (or  anticipated portfolio securities)  against changes in
prevailing interest rates. The Fund may purchase or sell index futures contracts
for the  purpose  of  hedging some  or  all  of its  portfolio  (or  anticipated
portfolio)  securities against changes in their prices (or the currency in which
they are  denominated). As  a futures  contract purchaser,  the Fund  incurs  an
obligation  to take delivery of a  specified amount of the obligation underlying
the contract at  a specified  time in  the future for  a specified  price. As  a
seller  of a  futures contract,  the Fund  incurs an  obligation to  deliver the
specified amount of the underlying obligation at a specified time in return  for
an agreed upon price.
 
    The  Fund  also may  purchase  and write  call  and put  options  on futures
contracts which are traded  on an exchange and  enter into closing  transactions
with respect to such options to terminate an existing position.
 
    New  futures  contracts, options  and other  financial products  and various
combinations thereof continue to be developed.  The Fund may invest in any  such
futures,  options or products as may be developed, to the extent consistent with
its investment objective and applicable regulatory requirements.
 
    RISKS OF  OPTIONS AND  FUTURES  TRANSACTIONS. The  Fund  may close  out  its
position  as writer of an option, or as a buyer or seller of a futures contract,
 
                                       12
<PAGE>
only if a  liquid secondary market  exists for options  or futures contracts  of
that  series. There is no assurance that  such a market will exist, particularly
in the case of OTC options, as such options may generally only be closed out  by
entering  into a closing purchase transaction  with the purchasing dealer. Also,
exchanges may limit the amount by which the price of many futures contracts  may
move  on any day. If  the price moves equal the  daily limit on successive days,
then it may  prove impossible to  liquidate a futures  position until the  daily
limit moves have ceased.
 
    While the futures contracts and options transactions to be engaged in by the
Fund  for  the  purpose  of  hedging the  Fund's  portfolio  securities  are not
speculative in nature, there are risks inherent in the use of such  instruments.
One  such  risk  is  that  the Investment  Manager  could  be  incorrect  in its
expectations as to  the direction or  extent of various  interest rate or  price
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  of the
futures contract. Another risk which  will arise in employing futures  contracts
to  protect against  the price  volatility of  portfolio securities  is that the
prices of securities, currencies and  indexes subject to futures contracts  (and
thereby the futures contract prices) may correlate imperfectly with the behavior
of  the U.S.  dollar cash  prices of the  Fund's portfolio  securities and their
denominated currencies.  See  the  Statement of  Additional  Information  for  a
further discussion of risks.
 
PORTFOLIO MANAGEMENT
 
    The  Fund's portfolio is  actively managed by its  Investment Manager with a
view  to  achieving  the  Fund's  investment  objective.  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 Taxable Fixed-Income Group, which
manages 24 funds and fund portfolios,  with approximately $13 billion in  assets
at  May 31, 1997. Peter  M. Avelar, Senior Vice  President of InterCapital and a
member of  InterCapital's  Taxable  Fixed-Income Group,  has  been  the  primary
portfolio  manager of the Fund since its inception. Mr. Avelar has been managing
portfolios consisting of fixed-income and equity securities at InterCapital  for
over five years.
    
 
    Although  the Fund  does not engage  in substantial short-term  trading as a
means of achieving its  investment objective, it  may sell portfolio  securities
without regard to the length of time they have been held, in accordance with the
investment  policies described earlier.  Pursuant to an  order of the Securities
and Exchange Commission, the Fund  may effect principal transactions in  certain
money  market instruments  with DWR. In  addition, the Fund  may incur brokerage
commissions on transactions conducted  through DWR. Under normal  circumstances,
it  is not  anticipated that  the portfolio  trading will  result in  the Fund's
portfolio turnover rate  exceeding 200%  in any one  year. The  Fund will  incur
underwriting  discount costs  (on underwritten  securities) and  brokerage costs
commensurate with its portfolio turnover  rate. Short-term gains and losses  may
result  from  such  portfolio transactions.  See  "Dividends,  Distributions and
Taxes" for a discussion of the tax implications of the Fund's trading policy.

INVESTMENT RESTRICTIONS
- --------------------------------------------------------------------------------
 
    The investment restrictions  listed below are  among the restrictions  which
have  been adopted  by the  Fund as  fundamental policies.  Under the Investment
Company Act of 1940,  as amended (the  "Act"), a fundamental  policy may not  be
changed  without the vote of a majority  of the outstanding voting securities of
the Fund, as defined in the Act. For purposes of the following limitations:  (i)
all  percentage  limitations  apply  immediately  after  a  purchase  or initial
investment,  and  (ii)  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. 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.  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,  its  agencies  or
instrumentalities.
 
   3. 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 any obligation issued
or   guaranteed   by   the   United   States   Government,   its   agencies   or
instrumentalities.
 
   4.  As to  75% of  its total  assets, purchase  more than  10% of  the voting
securities of any issuer.
 
   
    Notwithstanding any other  investment policy  or restriction,  the Fund  may
seek  to achieve its investment objective  by investing all or substantially all
of its  assets  in another  investment  company having  substantially  the  same
investment objective and policies as the Fund.
    
 
PURCHASE OF FUND SHARES
- --------------------------------------------------------------------------------
 
    The  Fund offers its  shares for sale  to the public  on a continuous basis.
Pursuant  to  a  Distribution  Agreement  between  the  Fund  and  Dean   Witter
Distributors  Inc. (the "Distributor"), an  affiliate of the Investment Manager,
shares of the Fund  are distributed by  the Distributor and  offered by DWR  and
other  brokers and dealers who have entered into agreements with the Distributor
("Selected Broker-Dealers"). The principal  executive office of the  Distributor
is located at Two World Trade Center, New York, New York 10048.
    The minimum initial purchase is $1,000. Minimum subsequent purchases of $100
or  more may  be made  by sending a  check, payable  to Dean  Witter High Income
Securities, 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  Broker-Dealer.  The minimum  initial  purchase in  the  case of
investments through  EasyInvest, 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
(including Individual Retirement 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. The offering price will be the
net  asset value per  share next determined  following receipt of  an order (see
"Determination of Net Asset Value").
 
                                       14
<PAGE>
   
    Shares of  the Fund  are sold  through  the Distributor  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. Since DWR and
other Selected Broker-Dealers forward investors' funds on settlement date,  they
will  benefit  from the  temporary use  of the  funds if  payment is  made prior
thereto. As noted above, orders placed directly with the Transfer Agent must  be
accompanied  by payment. Investors will be  entitled to receive income dividends
and capital  gains distributions  if their  order is  received by  the close  of
business   on  the  day  prior  to  the  record  date  for  such  dividends  and
distributions. 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  High Yield  Securities Inc.,  an
open-end  investment company with investment  objectives and policies similar to
those of the Fund. Unlike  the Fund, however, shares  of Dean Witter High  Yield
Securities  Inc. are offered  to the public  with a sales  charge imposed at the
time of purchase, rather than a  contingent deferred sales charge assessed  upon
redemption  within  five 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 High Yield Securities Inc. 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 under 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 0.80% 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. This fee is treated by the Fund as an expense in the year it is accrued.
A  portion of the fee payable pursuant to the Plan, equal to 0.20% of the Fund's
average daily net assets, is characterized  as a service fee within the  meaning
of  NASD guidelines.  The service  fee is a  payment made  for personal services
and/or the maintenance of shareholder accounts.
 
    Amounts paid  under  the Plan  are  paid  to the  Distributor  for  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's
account executives and others 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. In addition, the  Distributor may utilize fees  paid pursuant to  the
Plan  to compensate DWR and other  Selected Broker-Dealers for their opportunity
costs in advancing such amounts,  which compensation would be  in the form of  a
carrying charge on any unreimbursed expenses.
 
                                       15
<PAGE>
   
    For  the fiscal year ended  March 31, 1997, the  Fund accrued payments under
the Plan amounting to $6,228,452, which amount  is equal to 0.80% of the  Fund's
average  daily net assets  for the period.  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 the  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  the  excess  distribution  expenses,
including the carrying charge described above, totalled $28,870,822 at March 31,
1997, which was equal to 2.56% of the Fund's net assets on such date.
    
 
    Because there  is no  requirement under  the Plan  that the  Distributor  be
reimbursed  for all  distribution expenses or  any requirement that  the Plan be
continued from year to year, such excess  amount, if any, 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 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. 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, (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  is valued at its  latest sale price on that
exchange 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 a security
is traded on  more than one  exchange, the  security is 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 bid price. When
market quotations are not readily available, including circumstances under which
it  is determined  by the Investment  Manager that  sale and 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 Board of Trustees.
    
 
    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   evaluations  by  its  staff,
 
                                       16
<PAGE>
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.
 
SHAREHOLDER SERVICES
- --------------------------------------------------------------------------------
 
    AUTOMATIC INVESTMENT OF DIVIDENDS AND  DISTRIBUTIONS.  All income  dividends
and  capital gains distributions  are automatically paid  in full and fractional
shares of the  Fund (or,  if specified by  the shareholder,  any other  open-end
investment   company  for  which  InterCapital   serves  as  investment  manager
(collectively, with the Fund, the "Dean Witter Funds")), unless the  shareholder
requests  that they be paid  in cash. Shares as acquired  are not subject to the
imposition of  a contingent  deferred sales  charge upon  their redemption  (see
"Redemptions and Repurchases").
 
    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 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").
 
    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
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.  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  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
corporations,  the self-employed,  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
 
    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  Intermediate
Term  U.S. Treasury Trust, Dean Witter Short-Term Bond Fund, Dean Witter Limited
Term Municipal Trust,  Dean Witter  Balanced Growth Fund,  Dean Witter  Balanced
Income   Fund  and  five  Dean  Witter   Funds  which  are  money  market  funds
 
                                       17
<PAGE>
(the foregoing eleven non-CDSC funds are hereinafter collectively referred to 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.
 
    An exchange to another CDSC fund or to 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 which are exchanged for shares of another CDSC fund having a
higher CDSC schedule than that of the Fund will be subject to the CDSC  schedule
of  the other CDSC fund, even if shares are subsequently re-exchanged for shares
of the Fund prior to redemption.  Concomitantly, shares of the Fund acquired  in
exchange  for shares of another CDSC fund having a lower 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
Fund  (calculated from  the last  day of  the month  in which  the Exchange Fund
shares were acquired), the  holding period (for the  purpose of determining  the
rate  of the CDSC) is  frozen. If those shares  are subsequently reexchanged for
shares of  a 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 a 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 exchanged  into an  Exchange Fund  on or  after April  23, 1990,  upon  a
redemption  of shares which  results in a  CDSC being imposed,  a credit (not to
exceed the amount of the CDSC) will be given in an amount equal to the  Exchange
Fund  12b-1  distribution  fees  incurred  on  or  after  that  date  which  are
attributable to  those  shares.  (Exchange  Fund  12b-1  distribution  fees  are
described in the prospectuses 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 ("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.
 
    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
 
                                       18
<PAGE>
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
have  been  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 the margin account.
 
    The  current prospectus for each  fund describes its investment objective(s)
and policies, and shareholders should obtain one and examine it carefully before
investing. Exchanges are subject to  the minimum investment requirement and  any
other  conditions imposed by each fund. In the case of any shareholder holding a
share certificate or  certificates, no  exchanges may  be made  until the  share
certificate(s)  have been  received by the  Transfer Agent and  deposited in the
shareholder's account.  An  exchange will  be  treated for  federal  income  tax
purposes  the  same  as a  repurchase  of  redemption of  shares,  on  which the
shareholder may realize a capital gain  or loss. However, the ability to  deduct
capital  losses on an  exchange may be  limited in situations  where there is an
exchange of  shares within  ninety  days after  the  shares are  purchased.  The
Exchange  Privilege is only available in states where an exchange may legally be
made.
 
    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  account   executive  (no  Exchange  Privilege
Authorization Form is required). Other shareholders (and those shareholders  who
are  clients  of DWR  or  other Selected  Broker-Dealers  but who  wish  to make
exchanges directly by writing or  telephoning the Transfer Agent) must  complete
and  forward to  the Transfer  Agent an  Exchange Privilege  Authorization Form,
copies of  which  may  be obtained  from  the  Transfer Agent,  to  initiate  an
exchange. If the Authorization Form is used, exchanges may be made in writing or
by contacting the Transfer Agent at (800) 869-NEWS (toll-free).
 
    The  Fund  will  employ  reasonable  procedures  to  confirm  that  exchange
instructions communicated over  the telephone are  genuine. Such procedures  may
include requiring various forms of personal identification such as name, mailing
address,  social security  or other tax  identification number and  DWR or other
Selected Broker-Dealer account number (if any). Telephone instructions may  also
be recorded. If such procedures are not employed, the Fund may be liable for any
losses due to unauthorized or fraudulent instructions.
 
    Telephone exchange instructions will be accepted if received by the Transfer
Agent  between 9:00 a.m. and 4:00  p.m., New York time, on  any day the New York
Stock Exchange is  open. Any  shareholder wishing to  make an  exchange who  has
previously  filed an Exchange Privilege Authorization  Form and who is unable to
reach the Fund  by telephone should  contact his  or her DWR  or other  Selected
Broker-Dealer  account  executive, if  appropriate, or  make a  written exchange
request. Shareholders are  advised that  during periods of  drastic economic  or
market  changes, it  is possible that  the telephone exchange  procedures may be
difficult to implement, although this has not been the experience with the  Dean
Witter Funds in the past.
 
    Shareholders  should  contact  their  DWR  or  other  Selected Broker-Dealer
account executive  or  the Transfer  Agent  for further  information  about  the
Exchange Privilege.

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 certificates with
a written request for redemption, along with any additional information required
by the Transfer Agent.
 
    CONTINGENT  DEFERRED SALES CHARGE.   Shares of  the Fund which  are held for
five 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 five years after purchase may,  however,
be  subject to  a charge  upon redemption. This  charge is  called a "contingent
deferred sales  charge" ("CDSC"),  and it  will be  a percentage  of the  dollar
amount  of shares redeemed and will be 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, as set
forth in the table below:
 
<TABLE>

                PURCHASE                   AS A PERCENTAGE OF
              PAYMENT MADE                  AMOUNT REDEEMED

Third...................................          2.0%
Fourth..................................          2.0%
Fifth...................................          1.0%
Sixth 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 five years  preceding the redemption;
(ii) the current net asset value of shares purchased more than five 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 or Custodial  Account under  Section 403(b)(7) of  the Internal  Revenue
Code,  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 Individual Retirement  Account or Custodial Account under
Section 403(b)(7)  of the  Internal  Revenue Code  following attainment  of  age
59 1/2); and (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.,
 
                                       20
<PAGE>
   
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 or the 401(k) Support Services Group of DWR serves as
recordkeeper  ("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  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 or  telegraphic request of  the shareholder. 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-Dealer,
reduced by any applicable CDSC.
 
    The  CDSC, if any, will be the only fee imposed by the Fund, the Distributor
or DWR or  other Selected  Broker-Dealer. The offer  by DWR  and other  Selected
Broker-Dealers  to  repurchase shares  may be  suspended  without notice  by the
Distributor 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 their 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, on sixty days' notice,
to  redeem 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 due to redemptions
by the shareholder have a value of less  than $100 or such lesser amount as  may
be  fixed  by  the  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
 
                                       21
<PAGE>
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 before the redemption is processed. No CDSC will be imposed on
any involuntary redemption.
 
DIVIDENDS, DISTRIBUTIONS AND TAXES
- --------------------------------------------------------------------------------
 
    DIVIDENDS AND DISTRIBUTIONS.   The Fund intends to  declare and pay  monthly
income  dividends and  to distribute  net short-term  and net  long-term capital
gains, if any, at least once each year. The Fund may, however, determine  either
to  distribute or to  retain all or part  of any 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  requests in  writing that  all dividends be  paid in  cash and such
request is received by the close of business on the day prior to the record date
for such  distributions.  (See "Shareholder  Services--Automatic  Investment  of
Dividends and Distributions".)
 
    TAXES.   Because the  Fund intends to  distribute all of  its net investment
income and net 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 on such income and capital gains.
 
    With  respect to the  Fund's investments in  zero coupon and payment-in-kind
bonds, the  Fund accrues  income prior  to  any actual  cash payments  by  their
issuers.  In order to comply with Subchapter  M of the Internal Revenue Code and
be 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  and payment-in-kind 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.
 
    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 they
are  derived from  net investment  income or  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 calendar quarter  of any year to shareholders of
record for that period which  are paid in the  following calendar year prior  to
February  1 will  be deemed  received by the  shareholder in  the prior calendar
year. Since the Fund's income is expected to be derived primarily from  interest
rather  than dividends,  only a  small portion,  if any,  of such  dividends and
distributions is  expected to  be eligible  for the  Federal dividends  received
deduction available to corporations.
 
    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. Capital  gains distributions are not eligible  for
the dividends received deduction. Capital gains may be generated by transactions
in options and futures contracts engaged in by the Fund.
 
    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.
 
    After the end of the calendar year, shareholders will receive a statement of
their  dividends  and capital  gains distributions  for tax  purposes, including
infor-
 
                                       22
<PAGE>
mation as to the portion taxable as  ordinary income and the portion taxable  as
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  should consult their tax advisers regarding specific questions
as to state or local taxes and as to the applicability of the foregoing to their
current federal tax situation.
 
PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------
 
    From time to time the Fund may  quote its "yield" and/or its "total  return"
in  advertisements and sales literature. Both the  yield and the total return of
the Fund  are based  on historical  earnings and  are not  intended to  indicate
future performance. The yield of the Fund is computed by dividing the Fund's net
investment  income over a 30-day  period by an average  value (using the average
number of shares entitled to receive dividends and the 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  "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 one, five  and ten years, or 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 all sales charges incurred
by shareholders, for  the stated  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.
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  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 in
ordinary circumstances  the Fund  does not  intend to  hold such  meetings.  The
Trustees  may call  Special Meetings of  Shareholders for  action by shareholder
vote as may be required  by the Act or the  Declaration of Trust. Under  certain
circumstances  the Trustees may be  removed by action of  the Trustees or by the
shareholders.
 
    Under Massachusetts law, shareholders of a business trust may, under certain
circumstances, be  held personally  liable as  partners for  obligations of  the
Fund.  However,  the  Declaration of  Trust  contains an  express  disclaimer of
shareholder liability for acts  or obligations of the  Fund, requires that  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 being unable  to
meet  its obligations is remote and, in  the opinion of Massachusetts counsel to
the Fund, the risk to Fund shareholders of personal liability is remote.
 
    CODE OF ETHICS.   Directors,  officers and employees  of InterCapital,  Dean
Witter Services Company Inc. and the Distributor are subject to a strict Code of
Ethics adopted by those companies. The Code of Ethics is intended to ensure that
the interests of shareholders and other clients are placed ahead of any personal
interest,  that no undue personal benefit is obtained from a person's employment
activities and that actual and potential  conflicts of interest are avoided.  To
achieve  these goals and comply with regulatory requirements, the Code of Ethics
requires, among other things, that personal securities transactions by employees
of the companies be subject to an  advance clearance process to monitor that  no
Dean  Witter Fund is engaged at the same time  in a purchase or sale of the same
security. The  Code of  Ethics bans  the purchase  of securities  in an  initial
public offering,
 
and also prohibits engaging in futures and options transactions and profiting on
short-term  trading (that is, a  purchase within sixty days of  a sale or a sale
within sixty  days  of  a  purchase) of  a  security.  In  addition,  investment
personnel  may not purchase or sell a security for their personal account within
thirty days before or after any transaction  in any Dean Witter Fund managed  by
them.  Any violations of the Code of  Ethics are subject to sanctions, including
reprimand, demotion  or suspension  or termination  of employment.  The Code  of
Ethics comports with regulatory requirements and the recommendations in the 1994
report by the Investment Company Institute Advisory Group on Personal Investing.
 
   
    MASTER/FEEDER  CONVERSION.  The  Fund reserves the right  to seek to achieve
its investment  objective  by  investing  all of  its  investable  assets  in  a
diversified,  open-end management investment company  having the same investment
objective and policies  and substantially  the same  investment restrictions  as
those applicable to the Fund.
    
 
    SHAREHOLDER  INQUIRIES.  All inquiries regarding the Fund should be directed
to the Fund at the telephone numbers or address set forth on the front cover  of
this Prospectus.

APPENDIX -- RATINGS OF INVESTMENTS
- --------------------------------------------------------------------------------
 
MOODY'S INVESTORS SERVICE INC. ("MOODY'S")
 
                                  BOND RATINGS
 
<TABLE>
<S>        <C>
Aaa        Bonds  which are rated Aaa are judged to  be of the best quality. They carry the
           smallest degree of investment risk and are generally referred to as "gilt edge."
           Interest payments are protected by a large or by an exceptionally stable  margin
           and  principal is  secure. While the  various protective elements  are likely to
           change, such  changes as  can be  visualized  are most  unlikely to  impair  the
           fundamentally strong position of such issues.
Aa         Bonds  which are  rated 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 over  the  future.  Uncertainty  of  position
           characterizes bonds in this class.
B          Bonds which are rated B generally lack characteristics of desirable investments.
           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.

                                       25

        CONDITIONAL  RATING:  Municipal bonds for which the security depends
    upon the completion of some act or the fulfillment of some condition are
    rated conditionally. These are 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
    corporate  and 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.
 
                            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.   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")
 
                                    BOND RATINGS
 
       A Standard  & Poor's  bond  rating is  a  current assessment  of  the
    creditworthiness  of an obligor  with respect to  a specific obligation.
    This assessment may take into consideration obligors such as guarantors,
    insurers, or lessees.
 
       The ratings are based on current information furnished by the  issuer
    or  obtained  by  Standard  & Poor's  from  other  sources  it considers
    reliable. The ratings are  based, in varying  degrees, on the  following
    considerations:  (1) likelihood  of default-capacity  and willingness of
    the obligor  as to  the  timely payment  of  interest and  repayment  of
    principal  in accordance with the terms of the obligation; (2) nature of
    and provisions of the  obligation; and (3)  protection afforded by,  and
    relative  position  of,  the  obligation  in  the  event  of bankruptcy,
    reorganization or other  arrangement under  the laws  of bankruptcy  and
    other laws affecting creditors' rights.
 
       Standard  & Poor's does  not perform an audit  in connection with any
    rating and may,  on occasion, rely  on unaudited financial  information.
    The  ratings  may be  changed,  suspended or  withdrawn  as a  result of
    changes in,  or  unavailability  of,  such  information,  or  for  other
    reasons.
 
<TABLE>
<S>        <C>
AAA        Debt rated AAA has the highest rating assigned by Standard & Poor's. Capacity to
           pay interest and repay principal is extremely strong.
AA         Debt rated AA has a very strong capacity to pay interest and repay principal and
           differs from the highest-rated issues only in small degree.
A          Debt  rated A has a strong capacity to pay interest and repay principal although
           they are  somewhat  more  susceptible  to the  adverse  effects  of  changes  in
           circumstances and economic conditions than debt in higher-rated categories.
</TABLE>

<PAGE>
<TABLE>
<S>        <C>
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  could  lead  to  inadequate
           capacity to meet timely interest and principal payment.
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  within the  major
           ratings categories.
           In  the case of municipal bonds, 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.

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

    Pursuant to an  Investment Management Agreement  (the "Agreement") with  the
Investment  Manager, the Fund has retained  the Investment Manager to manage the
investment of  the  Fund's assets,  including  the  placing of  orders  for  the
purchase  and sale of  portfolio securities. The  Investment Manager obtains and
evaluates such  information  and  advice relating  to  the  economy,  securities
markets,  and  specific  securities  as  it  considers  necessary  or  useful to
continuously manage  the assets  of the  Fund in  a manner  consistent with  its
investment objective.
 
    Under  the  terms  of the  Agreement,  in  addition to  managing  the Fund's
investments, the Investment Manager  maintains certain of  the Fund's books  and
records  and  furnishes,  at its  own  expense, such  office  space, facilities,
equipment, clerical help and bookkeeping and certain legal services as the  Fund
may reasonably require in the conduct of its business, including the preparation
of  prospectuses,  statements of  additional  information, proxy  statements and
reports required  to be  filed  with federal  and state  securities  commissions
(except  insofar as the  participation or assistance  of independent accountants
and attorneys  is,  in the  opinion  of  the Investment  Manager,  necessary  or
desirable).  In  addition,  the  Investment Manager  pays  the  salaries  of all
personnel, including officers of the Fund,  who are employees of the  Investment
Manager.  The Investment Manager also bears the cost of telephone service, heat,
light, power and other  utilities provided to the  Fund. The Investment  Manager
has retained DWSC to perform its administrative services under the Agreement.
 
    The Fund pays all expenses incurred in its operation. Expenses not expressly
assumed  by the Investment Manager under the  Agreement or by the Distributor of
the  Fund's  shares,  Dean  Witter  Distributors  Inc.  ("Distributors"  or  the
"Distributor")  (see "Purchase of Fund  Shares"), will be paid  by the Fund. The
expenses borne by the Fund include, but are not limited to: charges and expenses
of any  registrar;  custodian, stock  transfer  and dividend  disbursing  agent;
brokerage  commissions;  taxes; engraving  and  printing of  share certificates;
registration costs of the Fund and its shares under federal and state securities
laws; the cost and expense of printing, including typesetting, and  distributing
Prospectuses   and  Statements  of  Additional   Information  of  the  Fund  and
supplements thereto to  the Fund's shareholders;  all expenses of  shareholders'
and  trustees'  meetings  and  of  preparing,  printing  and  mailing  of  proxy
statements and reports to shareholders; fees and travel expenses of trustees  or
members  of  any  advisory board  or  committee  who are  not  employees  of the
Investment Manager or  any corporate  affiliate of the  Investment Manager;  all
expenses incident to any dividend, withdrawal or redemption options; charges and
expenses  of any outside service used for pricing of the Fund's shares; fees and
expenses of  legal  counsel, including  counsel  to  the trustees  who  are  not
interested  persons  of the  Fund or  of the  Investment Manager  (not including
compensation or  expenses  of attorneys  who  are employees  of  the  Investment
Manager)  and independent accountants; membership dues of industry associations;
interest on the Fund's  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
(depending upon the  nature of the  legal claim, liability  or lawsuit) and  all
other costs of the Fund's operations properly payable by the Fund.
 
   
    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 0.50% to the daily net assets of the Fund up to $500 million and  0.425%
to  the Fund's daily net assets over $500 million. Total compensation accrued to
the Investment Manager for the period  June 2, 1994 (commencement of the  Fund's
operations) through March 31, 1995
    
 
                                       4

pursuant  to the Agreement amounted to  $350,117. This compensation reflects the
waiver of the investment management fee during a portion of the period. Had  the
fee  not been  waived, compensation  payable to  the Investment  Manager for the
period pursuant to the Agreement would have amounted to $374,452. For the fiscal
years ended  March  31,  1996  and  March  31,  1997,  the  Fund  accrued  total
compensation  to  the  Investment  Manager  in  the  amounts  of  $1,650,429 and
$3,685,133, respectively.
    
 
    The Agreement  provides that  in  the absence  of willful  misfeasance,  bad
faith, gross negligence or reckless disregard of its obligations thereunder, the
Investment Manager is not liable to the Fund or any of its investors for any act
or omission by the Investment Manager or for any losses sustained by the Fund or
its  investors. The  Agreement in no  way restricts the  Investment Manager from
acting as investment manager or adviser to others.
 
    The Investment Manager paid the organizational expenses of the Fund incurred
prior to the offering of the  Fund's shares. The Fund reimbursed the  Investment
Manager  for such expenses. The Fund will defer and will amortize the reimbursed
expenses on the straight line method over a period not to exceed five years from
the date of commencement of the Fund's operations.
 
   
    The Agreement was initially  approved by the Trustees  on February 21,  1997
and by the shareholders of the Fund at a Special Meeting of Shareholders held on
May  21, 1997.  The Agreement is  substantially identical to  a prior investment
management agreement which  was initially approved  by the Trustees  on May  10,
1994  and by  InterCapital as  the then  sole shareholder  on May  10, 1994. The
Agreement may be terminated at any time, without penalty, on thirty days' notice
by the Trustees of  the Fund, by  the holders of a  majority of the  outstanding
shares of the Fund, as defined in the Investment Company Act of 1940, as amended
(the  "Act"), or  by the  Investment Manager.  The Agreement  will automatically
terminate in the event of its assignment (as defined in the Act).
    
 
   
    Under its terms, the  Agreement has an initial  term ending April 30,  1999,
and  will continue in effect from  year to year thereafter, provided continuance
of the Agreement is approved at least annually  by the vote of the holders of  a
majority of the outstanding shares of the Fund, as defined in the Act, or by the
Trustees of the Fund; provided that in either event such continuance is approved
annually  by the  vote of a  majority of  the Trustees of  the Fund  who are not
parties to the Agreement or "interested persons" (as defined in the Act) of  any
such  party (the "Independent Trustees"), which vote must be cast in person at a
meeting called for the purpose of voting on such approval.
    
 
    The Fund has acknowledged that the name "Dean Witter" is a property right of
DWR. The Fund has agreed that DWR or its parent company may use, or at any  time
permit  others to use, the name "Dean Witter".  The Fund has also agreed that in
the  event  the  Agreement  is   terminated,  or  if  the  affiliation   between
InterCapital  and its parent company 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;  as noted above, Mr.
Hedien's term will commence  on September 1, 1997.  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 83 Dean Witter Funds, comprised of
126 portfolios. As of May 31, 1997,  the Dean Witter Funds had total net  assets
of approximately $86.4 billion and more than five million shareholders.
    
 
   
    Six  Trustees and Mr. Hedlien (77% of  the total number) have no affiliation
or business connection with InterCapital or any of its affiliated persons and do
not own any stock or other  securities issued by InterCapital's parent  company,
MSDWD.  These are the  "disinterested" or "independent"  Trustees. The other two
Trustees (the "management Trustees") are  affiliated with InterCapital. Four  of
the 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 current  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.
    
 
                                       8
<PAGE>
   
    The  Committee of the  Independent Trustees is  charged with recommending to
the full Board  approval of management,  advisory and administration  contracts,
Rule  12b-1  plans  and distribution  and  underwriting  agreements; continually
reviewing Fund performance;  checking on  the pricing  of portfolio  securities,
brokerage  commissions, transfer agent costs  and performance, and trading among
Funds in the  same complex; and  approving fidelity bond  and related  insurance
coverage and allocations, as well as other matters that arise from time to time.
The Independent Trustees are required to select and nominate individuals to fill
any  Independent Trustee vacancy on the Board of  any Fund that has a Rule 12b-1
plan of distribution. Most of the Dean Witter Funds have such a plan.
    
 
   
    The Audit  Committee is  charged with  recommending to  the full  Board  the
engagement  or  discharge  of  the  Fund's  independent  accountants;  directing
investigations into matters  within the  scope of  the independent  accountants'
duties,  including the power  to retain outside  specialists; reviewing with the
independent accountants the audit plan  and results of the auditing  engagement;
approving  professional  services provided  by  the independent  accountants and
other accounting firms prior to the performance of such services; reviewing  the
independence  of the independent accountants; considering the range of audit and
non-audit fees;  reviewing  the  adequacy  of  the  Fund's  system  of  internal
controls;  and preparing  and submitting Committee  meeting minutes  to the full
Board.
    
 
   
    Finally, the  Board of  each  Fund has  formed  a Derivatives  Committee  to
establish  parameters for and oversee the activities of the Fund with respect to
derivative investments, if any, made by the Fund.
    
 
   
DUTIES OF CHAIRMAN OF COMMITTEE OF THE INDEPENDENT TRUSTEES AND AUDIT COMMITTEE
    
 
   
    The Chairman of  the Committee  of the  Independent Trustees  and the  Audit
Committee  maintains an  office at  the Funds' headquarters  in New  York. He is
responsible for keeping abreast of regulatory and industry developments and  the
Funds'  operations and management. He  screens and/or prepares written materials
and identifies  critical  issues  for  the  Independent  Trustees  to  consider,
develops  agendas  for Committee  meetings, determines  the  type and  amount of
information that the Committees will need to form a judgment on various  issues,
and  arranges to have  that information furnished to  Committee members. He also
arranges for  the services  of independent  experts and  consults with  them  in
advance  of meetings  to help  refine reports and  to focus  on critical issues.
Members of the Committees believe that the person who serves as Chairman of both
Committees and guides their efforts is  pivotal to the effective functioning  of
the Committees.
    
 
   
    The  Chairman of the  Committees also maintains  continuous contact with the
Funds' management, with independent counsel to the Independent Trustees and with
the Funds' independent auditors.  He arranges for a  series of special  meetings
involving  the  annual  review  of  investment  advisory,  management  and other
operating contracts of  the Funds  and, on  behalf of  the Committees,  conducts
negotiations with the Investment Manager and other service providers. In effect,
the  Chairman of the Committees  serves as a combination  of chief executive and
support staff of the Independent Trustees.
    
 
   
    The Chairman of  the Committee  of the  Independent Trustees  and the  Audit
Committee  is  not  employed by  any  other  organization and  devotes  his time
primarily to  the services  he performs  as Committee  Chairman and  Independent
Trustee  of the Dean Witter Funds and  as an Independent Trustee and, 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
    
 
                                       9
<PAGE>
   
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.
    
 
   
CASH 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 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 March 31, 1997.

    As of the date of this Statement  of Additional Information, 57 of the  Dean
Witter  Funds, not 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

<PAGE>
   
such Fund referred to as an "Adopting Fund" and each such Trustee referred to as
an  "Eligible Trustee")  is entitled  to retirement  payments upon  reaching the
eligible retirement age (normally, after attaining age 72). Annual payments  are
based  upon length of service. Currently, upon retirement, each Eligible Trustee
is entitled to  receive from  the Adopting  Fund, commencing  as of  his or  her
retirement  date and continuing for the remainder  of his or her life, an annual
retirement benefit (the "Regular Benefit") equal to 25.0% of his or her Eligible
Compensation plus 0.4166666% of such  Eligible Compensation for each full  month
of  service as an Independent Director or Trustee of any Adopting Fund in excess
of five years up to a maximum of 50.0% after ten years of service. The foregoing
percentages may be changed by the Board.(1) "Eligible Compensation" is one-fifth
of the total  compensation earned by  such Eligible Trustee  for service to  the
Adopting  Fund  in  the five  year  period prior  to  the date  of  the Eligible
Trustee's retirement. Benefits under the  retirement program are not secured  or
funded by the Adopting Funds.
    
 
   
    The  following  table illustrates  the  retirement benefits  accrued  to the
Fund's Independent Trustees by the 57 Dean Witter Funds (not 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 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.
    
 
   
(2)  Based on  current levels  of compensation.  Amount of  annual benefits also
    varies depending on the Trustee's elections described in Footnote (1) above.
    
 
   
    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
- --------------------------------------------------------------------------------
 
    REPURCHASE AGREEMENTS.   As discussed in  the Prospectus, when  cash may  be
available  for only  a few days,  it may be  invested by the  Fund in repurchase
agreements until such time as it may otherwise be invested or used for  payments
of  obligations of the Fund. These agreements, which  may be viewed as a type of
secured lending by the  Fund, typically involve the  acquisition by the Fund  of
debt securities from a selling financial institution such as a bank, savings and
loan  association or  broker-dealer. The agreement  provides that  the Fund will
sell back to  the institution,  and that  the institution  will repurchase,  the
underlying  security ("collateral") at a specified price  and at a fixed time in
the future, usually  not more than  seven days  from the date  of purchase.  The
collateral  will be  maintained in  a segregated account  and will  be marked to
market daily to determine that the value of the collateral, as specified in  the
 
                                       11
<PAGE>
agreement,  does not decrease below the purchase price plus accrued interest. If
such  decrease  occurs,  additional  collateral  will  be  requested  and,  when
received, added to the account to maintain full collateralization. The Fund will
accrue  interest from the institution  until the time when  the repurchase is to
occur. Although such date  is deemed by the  Fund to be the  maturity date of  a
repurchase  agreement,  the  maturities  of  securities  subject  to  repurchase
agreements are not subject to any limits.
 
   
    While repurchase agreements involve certain risks not associated with direct
investments in debt securities, the Fund follows procedures designed to minimize
such risks. These procedures include effecting repurchase transactions only with
large,  well-capitalized  and  well-established  financial  institutions   whose
financial  condition  will be  continually monitored  by the  Investment Manager
subject to  procedures established  by the  Board of  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. It
is the current policy of the Fund not to invest in repurchase agreements that do
not mature within  seven days if  any such investment,  together with any  other
illiquid  assets held by the  Fund, amounts to more than  15% of its net assets.
The Fund's  investments in  repurchase agreements  may at  times be  substantial
when,   in  the  view  of  the  Investment  Manager,  liquidity,  tax  or  other
considerations warrant. For the fiscal year  ended March 31, 1997, the Fund  did
not  enter into any repurchase agreements in an amount exceeding 5% of its total
net assets.
    
 
    LENDING OF  PORTFOLIO SECURITIES.    Consistent with  applicable  regulatory
requirements, the Fund may lend its portfolio securities to brokers, dealers and
other  financial institutions, provided that such loans are callable at any time
by the Fund (subject to notice provisions described below), and are at all times
secured by  cash or  cash  equivalents, which  are  maintained in  a  segregated
account  pursuant to applicable regulations  and that are equal  to at least the
market value, determined daily, of the loaned securities. The advantage of  such
loans  is that the Fund continues to receive the income on the loaned securities
while at  the  same time  earning  interest on  the  cash amounts  deposited  as
collateral,  which will be invested in short-term obligations. 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. A loan may be terminated by
the borrower on one business days' notice, or by the Fund on four business days'
notice.  If the borrower fails to deliver the loaned securities within four days
after receipt  of notice,  the Fund  could  use the  collateral to  replace  the
securities  while holding the borrower liable for any excess of replacement cost
over collateral. As with any extensions of  credit, there are risks of delay  in
recovery  and in  some cases even  loss of  rights in the  collateral should the
borrower of the securities fail  financially. However, these loans of  portfolio
securities  will only  be made to  firms deemed  by the Fund's  management to be
creditworthy and when the income which  can be earned from such loans  justifies
the  attendant risks. Upon termination of the  loan, the borrower is required to
return the securities to the Fund. Any  gain or loss in the market price  during
the  loan period would inure to the Fund. The creditworthiness of firms to which
the Fund lends its portfolio securities will be monitored on an ongoing basis by
the Investment  Manager  pursuant to  procedures  adopted and  reviewed,  on  an
ongoing basis, by the Board of Trustees of the Fund.
 
    When  voting or consent rights which accompany loaned securities pass to the
borrower, the Fund will follow the  policy of calling the loaned securities,  to
be  delivered within one day after notice, to permit the exercise of such rights
if the matters involved would have a material effect on the Fund's investment in
such loaned securities.  The Fund will  pay reasonable finder's,  administrative
and custodial fees in connection with a loan of its securities.
 
    WHEN-ISSUED  AND DELAYED  DELIVERY SECURITIES  AND FORWARD  COMMITMENTS.  As
discussed in the Prospectus, from time to time 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
 
                                       12
<PAGE>
   
month  or more after the  date of commitment. 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.  The  securities  so
purchased or sold are subject to market fluctuation and no interest or dividends
accrue to the purchaser prior to the settlement date. 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, the 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
liquid portfolio securities equal in value to commitments to purchase securities
on a when-issued, delayed delivery or  forward commitment basis. Subject to  the
foregoing  restrictions, the Fund may purchase  securities on such basis without
limit. During the fiscal year  ended March 31, 1997,  the Fund did not  purchase
any securities on a when-issued and delayed delivery basis.
    
 
   
    WHEN, AS AND IF ISSUED SECURITIES.  As discussed in the Prospectus, 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 in the portfolio of 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  maintain  cash  or  cash
equivalents  or other liquid  portfolio securities equal  in value to recognized
commitments for such securities. Once a segregated account has been established,
if the anticipated event does not occur  and the securities are not issued,  the
Fund  will  have  lost  an  investment  opportunity.  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 Fund may also sell securities on a "when,
as and if issued" basis provided that  the issuance of the security will  result
automatically from the exchange or conversion of a security owned by the Fund at
the  time of the sale. During the fiscal year ended March 31, 1997, the Fund did
not purchase any securities on a when, as and if issued basis in an amount which
exceeded 5% of its total net assets.
    
 
    PRIVATE PLACEMENTS.  As discussed in the Prospectus, the Fund may invest  up
to  10% of its total  assets in securities which  are subject to restrictions on
resale because they have not been  registered under the Securities Act of  1933,
as   amended  (the  "Securities  Act"),  or  which  are  otherwise  not  readily
marketable. (Securities  eligible  for  resale  pursuant to  Rule  144A  of  the
Securities Act, and determined to be liquid pursuant to the procedures discussed
in  the  following paragraph,  are not  subject  to the  foregoing restriction.)
Limitations on the resale of such securities may have an adverse effect on their
marketability, and  may prevent  the Fund  from disposing  of them  promptly  at
reasonable  prices. The Fund  may have to  bear the expense  of registering such
securities for  resale and  the risk  of substantial  delays in  effecting  such
registration.
 
    The  Securities and Exchange Commission ("SEC")  has adopted Rule 144A under
the Securities Act,  which permits  the Fund  to sell  restricted securities  to
qualified  institutional  buyers  without  limitation.  The  Investment Manager,
pursuant to  procedures  adopted  by the  Trustees  of  the Fund,  will  make  a
determination  as to the liquidity of  each restricted security purchased by the
Fund. The procedures require that the following factors be taken into account in
making a liquidity determination: (1) the  frequency of trades and price  quotes
for  the security; (2) the number of  dealers and other potential purchasers who
have issued quotes on the security; (3) any dealer undertakings to make a market
in the
 
                                       13
<PAGE>
security; and (4) the nature of the  security and the nature of the  marketplace
trades  (the time needed  to dispose of  the security, the  method of soliciting
offers, and the mechanics of transfer).  If a restricted security is  determined
to be "liquid", such security will not be included within the category "illiquid
securities",  which under the SEC's  current policies may not  exceed 15% of the
Fund's net assets, and will not be subject to the 10% limitation set out in  the
preceding paragraph.
 
    The  Rule 144A marketplace of sellers  and qualified institutional buyers is
new and still developing and may take a period of time to develop into a  mature
liquid  market. As  such, the  market for  certain private  placements purchased
pursuant to Rule  144A may be  initially small or  may, subsequent to  purchase,
become  illiquid. Furthermore,  the Investment  Manager may  not posses  all the
information concerning an issue  of securities that it  wishes to purchase in  a
private  placement  to  which  it  would  normally  have  had  access,  had  the
registration statement necessitated  by a  public offering been  filed with  the
Securities and Exchange Commission.
 
    REVERSE  REPURCHASE  AGREEMENTS  AND  DOLLAR ROLLS.    As  discussed  in the
Prospectus, the Fund may also use reverse repurchase agreements and dollar rolls
as part of its investment strategy. Reverse repurchase agreements involve  sales
by  the Fund of portfolio  assets concurrently with an  agreement by the Fund to
repurchase the same  assets at a  later date  at a fixed  price. Generally,  the
effect  of such a  transaction is that the  Fund can recover all  or most of the
cash invested  in the  portfolio  securities involved  during  the term  of  the
reverse  repurchase agreement, while it will be able to keep the interest income
associated  with  those  portfolio   securities.  Such  transactions  are   only
advantageous  if  the  interest  cost  to the  Fund  of  the  reverse repurchase
transaction is less than the cost of obtaining the cash otherwise.
 
    The Fund may enter into dollar rolls in which the Fund sells securities  for
delivery  in  the  current  months and  simultaneously  contracts  to repurchase
substantially similar (same type  and coupon) securities  on a specified  future
date.  During the roll period,  the Fund forgoes principal  and interest paid on
the securities. The Fund  is compensated by the  difference between the  current
sales  price and the lower forward price for the future purchase (often referred
to as the "drop") as well as by the interest earned on the cash proceeds of  the
initial sale.
 
   
    The  Fund will  establish a  segregated account  with its  custodian bank in
which it  will  maintain  cash,  U.S.  Government  Securities  or  other  liquid
portfolio  securities equal  in value to  its obligations in  respect of reverse
repurchase agreements and dollar rolls. Reverse repurchase agreements and dollar
rolls involve the  risk that  the market  value of  the securities  the Fund  is
obligated  to repurchase  under the agreement  may decline  below the repurchase
price. In the event the buyer of securities under a reverse repurchase agreement
or dollar roll  files for  bankruptcy or becomes  insolvent, the  Fund's use  of
proceeds of the agreement may be restricted pending a determination by the other
party,  or its trustee or receiver, whether  to enforce the Fund's obligation to
repurchase the securities.  Reverse repurchase agreements  and dollar rolls  are
speculative  techniques involving leverage, and are considered borrowings by the
Fund.
    
 
    ZERO COUPON SECURITIES.   As discussed in the  Prospectus, 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 at least a portion of 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
 
                                       14
<PAGE>
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).
 
    RIGHTS AND WARRANTS.   As  stated in the  Prospectus, the  Fund may  acquire
rights  and warrants which are attached to other securities in its portfolio, or
which are issued  as a  distribution by  the issuer of  a security  held in  its
portfolio. Warrants are, in effect, an option to purchase equity securities at a
specific  price, generally  valid for  a specific  period of  time, and  have no
voting rights,  pay  no  dividends  and  have no  rights  with  respect  to  the
corporation  issuing them. The  Fund does not  anticipate acquiring any warrants
during its fiscal year ending                   .
 
    CONVERTIBLE SECURITIES.    As  stated  in the  Prospectus,  certain  of  the
fixed-income  securities purchased  by the Fund  may be  convertible into common
stock of the issuer.  Convertible securities rank senior  to common stocks in  a
corporation's  capital  structure  and,  therefore, entail  less  risk  than the
corporation's common stock. The value of a convertible security is a function of
its "investment value" (its value as if it did not have a conversion privilege),
and its "conversion value" (the security's worth if it were to be exchanged  for
the underlying security, at market value, pursuant to its conversion privilege).
 
    To the extent that a convertible security's investment value is greater than
its  conversion  value,  its  price  will  be  primarily  a  reflection  of such
investment value and its  price will be likely  to increase when interest  rates
fall and decrease when interest rates rise, as with a fixed-income security (the
credit  standing of the issuer and other factors  may also have an effect on the
convertible security's value).  If the conversion  value exceeds the  investment
value,  the price  of the  convertible security  will rise  above its investment
value and, in  addition, will sell  at some premium  over its conversion  value.
(This  premium  represents  the  price  investors are  willing  to  pay  for the
privilege of purchasing a  fixed-income security with  a possibility of  capital
appreciation  due to the conversion  privilege.) At such times  the price of the
convertible security  will tend  to fluctuate  directly with  the price  of  the
underlying  equity security. Convertible securities may be purchased by the Fund
at varying price levels above their investments values and/ or their  conversion
values in keeping with the Fund's objective.
 
    FOREIGN  SECURITIES.    As  stated  in  the  Prospectus,  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.
 
                                       15
<PAGE>
    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.
 
   
    FORWARD  FOREIGN CURRENCY EXCHANGE CONTRACTS.   As stated in the Prospectus,
the Fund may enter  into forward foreign  currency exchange contracts  ("forward
contracts")  as a hedge  against fluctuations in  future foreign exchange rates.
The Fund will  conduct its foreign  currency exchange transactions  either on  a
spot  (i.e., cash)  basis at  the spot rate  prevailing in  the foreign currency
exchange market, or through entering into forward contracts to purchase or  sell
foreign  currencies. A  forward contract involves  an obligation  to purchase or
sell a specific currency at a future date, which may be any fixed number of days
from the date of the contract agreed upon by the parties, at a price set at  the
time  of  the  contract. These  contracts  are  traded in  the  interbank market
conducted directly  between  currency  traders (usually  large,  commercial  and
investment  banks)  and their  customers. Such  forward  contracts will  only be
entered into with  United States  banks and  their foreign  branches or  foreign
banks,  insurance companies and  other dealers whose assets  total $1 billion or
more.  A  forward  contract  generally  has  no  deposit  requirement,  and   no
commissions are charged at any stage for trades.
    
 
    When  management  of the  Fund believes  that the  currency of  a particular
foreign country may suffer  a substantial movement against  the U.S. dollar,  it
may  enter into a  forward contract to purchase  or sell, for  a fixed amount of
dollars or  other currency,  the amount  of foreign  currency approximating  the
value  of some  or all  of the Fund's  portfolio securities  denominated in such
foreign currency.
 
    The Fund will enter into forward contracts under various circumstances. When
the Fund  enters  into  a contract  for  the  purchase or  sale  of  a  security
denominated  in a foreign currency, it may, for example, desire to "lock in" the
price of the security in U.S. dollars  or some other foreign currency which  the
Fund  is  temporarily  holding in  its  portfolio.  By entering  into  a forward
contract for  the purchase  or sale,  for a  fixed amount  of dollars  or  other
currency,  of the amount of foreign currency involved in the underlying security
transactions, the Fund will  be able to protect  itself against a possible  loss
resulting  from an adverse change in the relationship between the U.S. dollar or
other currency which is being used for the security purchase (by the Fund or the
counterparty) and  the foreign  currency in  which the  security is  denominated
during  the period between the  date on which the  security is purchased or sold
and the date on which payment is made or received.
 
    At other times, when,  for example, the  Fund's Investment Manager  believes
that  the  currency of  a particular  foreign country  may suffer  a substantial
decline against the  U.S. dollar or  some other foreign  currency, the Fund  may
enter  into a forward contract  to sell, for a fixed  amount of dollars or other
 
                                       16
<PAGE>
currency, the amount of foreign currency approximating the value of some or  all
of  the Fund's securities  holdings (or securities which  the Fund has purchased
for its  portfolio)  denominated  in  such  foreign  currency.  Under  identical
circumstances,  the Fund may enter into a  forward contract to sell, for a fixed
amount of U.S. dollars  or other currency, an  amount of foreign currency  other
than  the  currency  in  which  the  securities  to  be  hedged  are denominated
approximating the value of some or all of the portfolio securities to be hedged.
This method  of  hedging,  called  "cross-hedging,"  will  be  selected  by  the
Investment  Manager when it is determined that the foreign currency in which the
portfolio securities are denominated has insufficient liquidity or is trading at
a discount as compared with some other  foreign currency with which it tends  to
move in tandem.
 
    In  addition,  when  the Fund's  Investment  Manager  anticipates purchasing
securities at  some time  in  the future,  and wishes  to  lock in  the  current
exchange  rate of the currency in which those securities are denominated against
the U.S.  dollar or  some other  foreign currency,  the Fund  may enter  into  a
forward  contract to purchase an amount of currency  equal to some or all of the
value of the anticipated purchase, for a  fixed amount of U.S. dollars or  other
currency.  The  Fund  may,  however,  close  out  the  forward  contract without
purchasing the security which was the subject of the "anticipatory" hedge.
 
   
    The Fund will not enter into forward contracts or maintain a net exposure to
such contracts where the consummation of  the contracts would obligate the  Fund
to  deliver an amount of  foreign currency in excess of  the value of the Fund's
portfolio securities or other assets denominated in that currency. Under  normal
circumstances,  consideration  of the  prospect  for currency  parities  will be
incorporated into  the longer  term  investment decisions  made with  regard  to
overall diversification strategies. However, the management of the Fund believes
that  it  is  important to  have  the  flexibility to  enter  into  such forward
contracts when it determines that the best interests of the Fund will be served.
The Fund's custodian bank will place  cash, U.S. Government securities or  other
appropriate  liquid portfolio securities in a  segregated account of the Fund in
an amount  equal to  the  value of  the Fund's  total  assets committed  to  the
consummation of forward contracts entered into under the circumstances set forth
above. If the value of the securities placed in the segregated account declines,
additional  cash or securities will be placed in the account on a daily basis so
that the value of the  account will equal the  amount of the Fund's  commitments
with respect to such contracts.
    
 
    Where,  for example, the Fund is  hedging a portfolio position consisting of
foreign securities denominated  in a foreign  currency against adverse  exchange
rate  moves vis-a-vis the U.S.  dollar, at the maturity  of the forward contract
for delivery by the  Fund of a  foreign currency, the Fund  may either sell  the
portfolio  security and make delivery of the  foreign currency, or it may retain
the security and  terminate its  contractual obligation to  deliver the  foreign
currency  by purchasing an  "offsetting" contract with  the same currency trader
obligating it to purchase,  on the same  maturity date, the  same amount of  the
foreign  currency (however, the ability  of the Fund to  terminate a contract is
contingent upon the willingness  of the currency trader  with whom the  contract
has  been entered into to permit an offsetting transaction). It is impossible to
forecast the  market value  of portfolio  securities at  the expiration  of  the
contract.  Accordingly, it may be necessary  for the Fund to purchase additional
foreign currency on the spot market (and  bear the expense of such purchase)  if
the market value of the security is less than the amount of foreign currency the
Fund  is obligated to deliver and if a decision is made to sell the security and
make delivery of the foreign currency.  Conversely, it may be necessary to  sell
on  the spot market some  of the foreign currency received  upon the sale of the
portfolio securities if its market value exceeds the amount of foreign  currency
the Fund is obligated to deliver.
 
    If  the Fund retains  the portfolio securities and  engages in an offsetting
transaction, the Fund will  incur a gain  or loss to the  extent that there  has
been  movement in  spot or forward  contract prices.  If the Fund  engages in an
offsetting transaction, it may subsequently enter into a new forward contract to
sell the  foreign currency.  Should  forward prices  decline during  the  period
between  the Fund's entering into  a forward contract for  the sale of a foreign
currency and the date it enters into an offsetting contract for the purchase  of
the  foreign currency, the Fund  will realize a gain to  the extent the price of
the currency it has
 
                                       17
<PAGE>
agreed to sell  exceeds the price  of the  currency it has  agreed to  purchase.
Should  forward prices increase, the  Fund will suffer a  loss to the extent the
price of  the currency  it  has agreed  to purchase  exceeds  the price  of  the
currency it has agreed to sell.
 
    If  the Fund purchases a fixed-income  security which is denominated in U.S.
dollars but which will pay  out its principal based upon  a formula tied to  the
exchange  rate between  the U.S.  dollar and  a foreign  currency, it  may hedge
against a decline  in the principal  value of  the security by  entering into  a
forward  contract to sell  an amount of  the relevant foreign  currency equal to
some or all of the principal value of the security.
 
   
    At times  when the  Fund has  written a  call option  on a  security or  the
currency  in  which it  is  denominated, it  may wish  to  enter into  a forward
contract to  purchase or  sell the  foreign currency  in which  the security  is
denominated.  A  forward contract  would,  for example,  hedge  the risk  of the
security on which a call option has been written declining in value to a greater
extent than the  value of the  premium received  for the option.  The Fund  will
maintain  with its Custodian at all  times, cash, U.S. Government securities, or
other liquid portfolio securities in a segregated account equal in value to  all
forward  contract obligations  and option  contract obligations  entered into in
hedge situations such as this.
    
 
    Although the Fund values its assets daily in terms of U.S. dollars, it  does
not  intend to convert its holdings of foreign currencies into U.S. dollars on a
daily basis. It will, however, do so from time to time, and investors should  be
aware  of the costs of currency conversion. Although foreign exchange dealers do
not charge a fee for  conversion, they do realize a  profit based on the  spread
between the prices at which they are buying and selling various currencies. Thus
a  dealer may offer  to sell a foreign  currency to the Fund  at one rate, while
offering a  lesser  rate of  exchange  should the  Fund  desire to  resell  that
currency to the dealer.
 
    In  all  of the  above  circumstances, if  the  currency in  which  the Fund
securities holdings (or anticipated portfolio securities) are denominated  rises
in  value with respect to the currency  which is being purchased (or sold), then
the Fund will have realized fewer gains  than had the Fund not entered into  the
forward  contracts.  Moreover,  the  precise matching  of  the  forward contract
amounts and the value of the securities involved will not generally be possible,
since the future value of such securities in foreign currencies will change as a
consequence of market  movements in the  value of those  securities between  the
date  the forward contract is entered into and  the date it matures. The Fund is
not required  to  enter  into  such transactions  with  regard  to  its  foreign
currency-denominated  securities and will not do so unless deemed appropriate by
the Investment  Manager.  The Fund  generally  will  not enter  into  a  forward
contract  with  a term  of greater  than one  year, although  it may  enter into
forward contracts for periods of  up to five years. The  Fund may be limited  in
its  ability to enter  into hedging transactions  involving forward contracts by
the Internal Revenue Code (the  "Code") requirements relating to  qualifications
as a regulated investment company (see "Dividends, Distributions and Taxes").
 
OPTIONS AND FUTURES TRANSACTIONS
 
    As stated in the Prospectus, the Fund may write covered call options against
securities  held in its portfolio and  covered put options on eligible portfolio
securities and stock indexes and purchase  options of the same series to  effect
closing  transactions, and  may hedge  against potential  changes in  the market
value  of   investments  (or   anticipated  investments)   and  facilitate   the
reallocation  of the  Fund's assets  into and  out of  equities and fixed-income
securities by  purchasing  put  and  call  options  on  portfolio  (or  eligible
portfolio)  securities and engaging in  transactions involving futures contracts
and options on such contracts. The Fund may also hedge against potential changes
in the market value of the  currencies in which its investments (or  anticipated
investments)  are denominated by  purchasing put and  call options on currencies
and engage in transactions involving  currency futures contracts and options  on
such contracts.
 
    Call  and put  options on  U.S. Treasury notes,  bonds and  bills and equity
securities  are  listed  on  Exchanges  and  are  written  in   over-the-counter
transactions ("OTC options"). Listed options are issued
 
                                       18
<PAGE>
by  the  Options  Clearing  Corporation  ("OCC")  and  other  clearing  entities
including foreign exchanges. Ownership  of a listed call  option gives the  Fund
the  right to buy from the OCC the  underlying security covered by the option at
the stated exercise  price (the price  per unit of  the underlying security)  by
filing an exercise notice prior to the expiration date of the option. The writer
(seller)  of the option  would then have the  obligation to sell  to the OCC the
underlying security at that exercise price  prior to the expiration date of  the
option,  regardless of its then current market  price. Ownership of a listed put
option would give the Fund the right to sell the underlying security to the  OCC
at  the stated exercise  price. Upon notice  of exercise of  the put option, the
writer of the put would have the obligation to purchase the underlying  security
from the OCC at the exercise price.
 
    OPTIONS  ON TREASURY BONDS AND NOTES.  Because trading in options written on
Treasury bonds and notes tends to center on the most recently auctioned  issues,
the  exchanges on which such securities  trade will not continue indefinitely to
introduce options with new expirations to replace expiring options on particular
issues. Instead,  the  expirations introduced  at  the commencement  of  options
trading  on a  particular issue will  be allowed  to run their  course, with the
possible addition of a  limited number of new  expirations as the original  ones
expire.  Options trading on each issue of bonds or notes will thus be phased out
as new options are listed on more recent issues, and options representing a full
range of expirations will not ordinarily  be available for every issue on  which
options are traded.
 
    OPTIONS ON TREASURY BILLS.  Because a deliverable Treasury bill changes from
week to week, writers of Treasury bill calls cannot provide in advance for their
potential   exercise  settlement  obligations  by   acquiring  and  holding  the
underlying security. However,  if the  Fund holds  a long  position in  Treasury
bills with a principal amount of the securities deliverable upon exercise of the
option,  the position may be  hedged from a risk standpoint  by the writing of a
call option. For so long as the  call option is outstanding, the Fund will  hold
the Treasury bills in a segregated account with its Custodian, so that they will
be treated as being covered.
 
    OPTIONS  ON FOREIGN CURRENCIES.  The Fund  may purchase and write options on
foreign currencies  for purposes  similar to  those involved  with investing  in
forward  foreign currency exchange  contracts. For example,  in order to protect
against  declines  in  the  dollar  value  of  portfolio  securities  which  are
denominated  in a  foreign currency,  the Fund  may purchase  put options  on an
amount of such foreign currency equivalent to the current value of the portfolio
securities involved. As a result, the Fund would be enabled to sell the  foreign
currency  for a fixed  amount of U.S.  dollars, thereby "locking  in" the dollar
value of the portfolio securities (less the amount of the premiums paid for  the
options).  Conversely, the Fund may purchase  call options on foreign currencies
in which securities it  anticipates purchasing are denominated  to secure a  set
U.S. dollar price for such securities and protect against a decline in the value
of  the U.S. dollar  against such foreign  currency. The Fund  may also purchase
call and put options to close out written option positions.
 
    The Fund may also write call options on foreign currency to protect  against
potential  declines in its portfolio securities which are denominated in foreign
currencies. If the  U.S. dollar  value of the  portfolio securities  falls as  a
result of a decline in the exchange rate between the foreign currency in which a
security  is denominated and the U.S. dollar, then a loss to the Fund occasioned
by such value  decline would be  ameliorated by  receipt of the  premium on  the
option  sold. At the  same time, however, the  Fund gives up  the benefit of any
rise in value of the relevant  portfolio securities above the exercise price  of
the  option and, in fact, only receives a benefit from the writing of the option
to the extent that the value of  the portfolio securities falls below the  price
of  the premium received. The Fund may also write options to close out long call
option positions.
 
    The markets in foreign  currency options are relatively  new and the  Fund's
ability  to establish and close out positions  on such options is subject to the
maintenance of a liquid secondary market. Although the Fund will not purchase or
write such options unless  and until, in  the opinion of  the management of  the
Fund, the market for them has developed sufficiently to ensure that the risks in
connection with such
 
                                       19
<PAGE>
options  are  not  greater than  the  risks  in connection  with  the underlying
currency, there can be  no assurance that a  liquid secondary market will  exist
for  a particular option at  any specific time. In  addition, options on foreign
currencies are affected by all of those factors which influence foreign exchange
rates and investments generally.
 
    The value  of  a foreign  currency  option depends  upon  the value  of  the
underlying  currency relative to the U.S. dollar.  As a result, the price of the
option position may vary with changes in the value of either or both  currencies
and  have  no  relationship to  the  investment  merits of  a  foreign security,
including foreign securities  held in a  "hedged" investment portfolio.  Because
foreign   currency  transactions  occurring  in  the  interbank  market  involve
substantially larger  amounts than  those that  may be  involved in  the use  of
foreign currency options, investors may be disadvantaged by having to deal in an
odd  lot market (generally  consisting of transactions of  less than $1 million)
for the underlying foreign currencies at prices that are less favorable than for
round lots.
 
    There is  no  systematic reporting  of  last sale  information  for  foreign
currencies  or  any  regulatory requirement  that  quotations  available through
dealers or other market sources be firm or revised on a timely basis.  Quotation
information  available is generally representative of very large transactions in
the interbank market and  thus may not  reflect relatively smaller  transactions
(i.e.,  less than $1 million)  where rates may be  less favorable. The interbank
market in foreign currencies is a global, around-the-clock market. To the extent
that the U.S. options  markets are closed while  the markets for the  underlying
currencies  remain open, significant price and  rate movements may take place in
the underlying markets that are not reflected in the options market.
 
    OTC OPTIONS.  Exchange-listed  options are issued by  the OCC which  assures
that  all transactions  in such options  are properly executed.  OTC options are
purchased from or sold (written) to dealers or financial institutions which have
entered into direct agreements with the  Fund. With OTC options, such  variables
as  expiration date, exercise price and premium  will be agreed upon between the
Fund and the  transacting dealer, without  the intermediation of  a third  party
such as the OCC. If the transacting dealer fails to make or take delivery of the
securities  underlying an option it has written, in accordance with the terms of
that option, the Fund would lose the premium paid for the option as well as  any
anticipated  benefit  of the  transaction. The  Fund will  engage in  OTC option
transactions only with primary U.S. Government securities dealers recognized  by
the Federal Reserve Bank of New York.
 
   
    COVERED  CALL WRITING.  The Fund is  permitted to write covered call options
on portfolio  securities and  the U.S.  dollar and  foreign currencies,  without
limit.  Generally, a call option is "covered" if the Fund owns, or has the right
to acquire,  without  additional  cash consideration  (or  for  additional  cash
consideration  held for the Fund  by its Custodian in  a segregated account) the
underlying security (currency) subject to the option except that in the case  of
call options on U.S. Treasury Bills, the Fund might own U.S. Treasury Bills of a
different  series from  those underlying the  call option, but  with a principal
amount and value  corresponding to  the exercise price  and a  maturity date  no
later  than that of the securities (currency) deliverable under the call option.
A call option  is also covered  if the Fund  holds a call  on the same  security
(currency)  as the underlying  security (currency) of  the written option, where
the exercise price of the  call used for coverage is  equal to or less than  the
exercise  price of the  call written or  greater than the  exercise price of the
call written if the mark to market difference is maintained by the Fund in cash,
U.S. Government securities or other  liquid portfolio securities which the  Fund
holds in a segregated account maintained with its Custodian.
    
 
    The  Fund  will receive  from the  purchaser, in  return for  a call  it has
written, a "premium"; i.e., the price  of the option. Receipt of these  premiums
may  better enable  the Fund  to achieve  a greater  total return  than would be
realized from holding the underlying securities (currency) alone. Moreover,  the
income  received from the  premium will offset  a portion of  the potential loss
incurred by the  Fund if  the securities  (currency) underlying  the option  are
ultimately  sold (exchanged) by  the Fund at  a loss. The  premium received will
fluctuate with varying economic  market conditions. If the  market value of  the
portfolio
 
                                       20
<PAGE>
securities  (or the  currencies in which  they are denominated)  upon which call
options have been written increases, the Fund may receive less total return from
the portion of its portfolio  upon which calls have  been written than it  would
have had such calls not been written.
 
    As regards listed options and certain OTC options, during the option period,
the  Fund  may be  required, at  any  time, to  deliver the  underlying security
(currency) against payment  of the exercise  price on any  calls it has  written
(exercise  of  certain  listed  and  OTC  options  may  be  limited  to specific
expiration dates).  This obligation  is terminated  upon the  expiration of  the
option period or at such earlier time when the writer effects a closing purchase
transaction.  A closing  purchase transaction  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.
 
    Closing purchase transactions are ordinarily effected to realize a profit on
an outstanding call  option to  prevent an underlying  security (currency)  from
being  called, to permit the sale of  an underlying security (or the exchange of
the underlying currency) or to enable the  Fund to write another call option  on
the  underlying security  (currency) with either  a different  exercise price or
expiration date or  both. Also,  effecting a closing  purchase transaction  will
permit  the cash or proceeds from the  concurrent sale of any securities subject
to the option to be used for other investments by the Fund. The Fund may realize
a net gain or  loss from a closing  purchase transaction depending upon  whether
the  amount of the premium received on the  call option is more or less than the
cost of  effecting the  closing purchase  transaction. Any  loss incurred  in  a
closing  purchase transaction  may be wholly  or partially  offset by unrealized
appreciation  in  the  market  value  of  the  underlying  security  (currency).
Conversely, a gain resulting from a closing purchase transaction could be offset
in  whole  or in  part or  exceeded  by a  decline in  the  market value  of the
underlying security (currency).
 
    If a call option expires unexercised, the Fund realizes a gain in the amount
of the premium on the option less the commission paid. Such a gain, however, may
be offset  by  depreciation in  the  market  value of  the  underlying  security
(currency)  during the option  period. If a  call option is  exercised, the Fund
realizes a gain  or loss  from the sale  of the  underlying security  (currency)
equal  to the difference  between the purchase price  of the underlying security
(currency) and the  proceeds of  the sale of  the security  (currency) plus  the
premium received for on the option less the commission paid.
 
    Options  written by a Fund normally have expiration dates of from up to nine
months (equity securities) to eighteen months (fixed-income securities) from the
date written. The  exercise price of  a call option  may be below,  equal to  or
above the current market value of the underlying security (currency) at the time
the option is written. See "Risks of Options and Futures Transactions," below.
 
   
    COVERED  PUT WRITING.  As a writer of  a covered put option, the Fund incurs
an obligation to buy  the security underlying the  option from the purchaser  of
the put, at the option's exercise price at any time during the option period, at
the purchaser's election (certain listed and OTC put options written by the Fund
will  be  exercisable  by the  purchaser  only on  a  specific date).  A  put is
"covered" if,  at  all  times,  the Fund  maintains,  in  a  segregated  account
maintained  on  its  behalf  at  the  Fund's  Custodian,  cash,  U.S. Government
securities or other high grade  obligations in an amount  equal to at least  the
exercise  price of the option, at all times during the option period. Similarly,
a short put  position could  be covered by  the Fund  by its purchase  of a  put
option  on the same security  as the underlying security  of the written option,
where the exercise price of  the purchased option is equal  to or more than  the
exercise  price of the  put written or less  than the exercise  price of the put
written if the mark to market difference is maintained by the Fund in cash, U.S.
Government securities or other liquid portfolio securities which the Fund  holds
in  a segregated account maintained at its  Custodian. In writing puts, the Fund
assumes the risk  of loss  should the market  value of  the underlying  security
decline  below the exercise price of the option (any loss being decreased by the
receipt of the premium on  the option written). In  the case of listed  options,
during the option period, the Fund may be required, at any time, to make payment
of the exercise price against delivery of the underlying security. The operation
of  and limitations on  covered put options in  other respects are substantially
identical to those of call options.
    
 
                                       21
<PAGE>
    The Fund will write put options for two purposes: (1) to receive the  income
derived  from  the premiums  paid  by purchasers;  and  (2) when  the Investment
Manager wishes to purchase the security  underlying the option at a price  lower
than its current market price, in which case it will write the covered put at an
exercise price reflecting the lower purchase price sought. The potential gain on
a  covered put option is limited to the premium received on the option (less the
commissions paid  on  the  transaction)  while the  potential  loss  equals  the
difference between the exercise price of the option and the current market price
of  the underlying securities when  the put is exercised,  offset by the premium
received (less the commissions paid on the transaction).
 
    PURCHASING CALL AND PUT OPTIONS.  The Fund may purchase listed and OTC  call
and  put options in amounts equalling up to 5% of its total assets. The Fund may
purchase call  options  in order  to  close out  a  covered call  position  (see
"Covered Call Writing" above) or purchase call options on securities they intend
to  purchase. The Fund  may also purchase  a call option  on foreign currency to
hedge against  an  adverse exchange  rate  move of  the  currency in  which  the
security  it  anticipates purchasing  is denominated  vis-a-vis the  currency in
which the exercise  price is  denominated. The purchase  of the  call option  to
effect  a closing transaction or a call written over-the-counter may be a listed
or an OTC option. In either case, the call purchased is likely to be on the same
securities (currencies)  and have  the  same terms  as  the written  option.  If
purchased  over-the-counter,  the option  would generally  be acquired  from the
dealer or financial institution which purchased the call written by the Fund.
 
    The Fund may purchase  put options on securities  (currency) which it  holds
(or  has the right to acquire) in its portfolio only to protect itself against a
decline in the value of the security (currency). If the value of the  underlying
security  (currency) were to fall below the  exercise price of the put purchased
in an amount greater than the premium paid for the option, the Fund would  incur
no  additional loss. The Fund may also purchase put options to close out written
put positions in a manner similar to call options closing purchase transactions.
In addition, the Fund may  sell a put option  which it has previously  purchased
prior  to the sale of  the securities (currency) underlying  such option. Such a
sale would result in a net gain or loss depending on whether the amount received
on the sale is more or less than the premium and other transaction costs paid on
the put option which is sold. Any such gain or loss could be offset in whole  or
in  part by a change in the  market value of the underlying security (currency).
If a put option purchased by the  Fund expired without being sold or  exercised,
the premium would be lost.
 
    RISKS  OF OPTIONS TRANSACTIONS.  During  the option period, the covered call
writer has, in return for  the premium on the  option, given up the  opportunity
for capital appreciation above the exercise price should the market price of the
underlying  security (or the currency in  which it is denominated) increase, but
has retained  the risk  of loss  should  the price  of the  underlying  security
(currency)  decline. The covered put writer also retains the risk of loss should
the market  value  of  the  underlying security  (currency)  decline  below  the
exercise  price  of the  option less  the premium  received on  the sale  of the
option. In both cases, the  writer has no control over  the time when it may  be
required  to fulfill its  obligation as a  writer of the  option. Once an option
writer has received  an exercise  notice, it  cannot effect  a closing  purchase
transaction  in  order to  terminate its  obligation under  the option  and must
deliver or receive the underlying securities (currency) at the exercise price.
 
   
    Prior to exercise or expiration, an  option position can only be  terminated
by  entering into  a closing  purchase or  sale transaction.  If a  covered call
option writer is unable to effect a closing purchase transaction or to  purchase
an  offsetting over-the-counter option,  it cannot sell  the underlying security
until the option expires or the option is exercised. Accordingly, a covered call
option writer  may  not  be  able to  sell  (exchange)  an  underlying  security
(currency) at a time when it might otherwise be advantageous to do so. A covered
put  option writer who is unable to  effect a closing purchase transaction or to
purchase an offsetting over-the-counter option  would continue to bear the  risk
of  decline in the market price of  the underlying security (currency) until the
option expires or is exercised. In addition, a coveredput writer would be unable
to utilize the amount held in cash or U.S. Government or other liquid  portfolio
securities  as security for  the put option for  other investment purposes until
the exercise or expiration of the option.
    
 
                                       22
<PAGE>
    The Fund's ability to  close out its  position as a writer  of an option  is
dependent  upon the existence of a  liquid secondary market on option Exchanges.
There is no assurance that such a market will exist, particularly in the case of
OTC options, as such options will generally only be closed out by entering  into
a closing purchase transaction with the purchasing dealer. However, the Fund may
be  able to purchase an offsetting option  which does not close out its position
as a writer but constitutes an asset of equal value to the obligation under  the
option  written. If the Fund is not able to either enter into a closing purchase
transaction or purchase an offsetting position, it will be required to  maintain
the  securities subject to the call, or  the collateral underlying the put, even
though it might not be advantageous to do so, until a closing transaction can be
entered into (or the option is exercised or expires).
 
    Among the possible reasons for the  absence of a liquid secondary market  on
an  Exchange are:  (i) insufficient  trading interest  in certain  options; (ii)
restrictions on  transactions  imposed  by an  Exchange;  (iii)  trading  halts,
suspensions  or other restrictions imposed with respect to particular classes or
series of  options or  underlying securities;  (iv) interruption  of the  normal
operations  on an Exchange; (v)  inadequacy of the facilities  of an Exchange or
the Options Clearing Corporation  ("OCC") to handle  current trading volume;  or
(vi)  a decision by one or more  Exchanges to discontinue the trading of options
(or a  particular class  or series  of options),  in which  event the  secondary
market  on that Exchange (or in that class  or series of options) would cease to
exist, although outstanding options on that Exchange that had been issued by the
OCC as  a result  of trades  on that  Exchange would  generally continue  to  be
exercisable in accordance with their terms.
 
    Exchanges limit the amount by which the price of a futures contract may move
on any day. If the price moves equal the daily limit on successive days, then it
may prove impossible to liquidate a futures position until the daily limit moves
have ceased. In the event of adverse price movements, the Fund would continue to
be  required to  make daily  cash payments of  variation margin  on open futures
positions. In such situations, if the Fund has insufficient cash, it may have to
sell portfolio securities to meet daily variation margin requirements at a  time
when  it may be disadvantageous to do so.  In addition, the Fund may be required
to take or  make delivery of  the instruments underlying  interest rate  futures
contracts  it holds at a time when it is disadvantageous to do so. The inability
to close out options and futures positions could also have an adverse impact  on
the Fund's ability to effectively hedge its portfolio.
 
    In the event of the bankruptcy of a broker through which the Fund engages in
transactions  in options, futures or options  thereon, the Fund could experience
delays and/or losses in liquidating open positions purchased or sold through the
broker and/or  incur a  loss of  all or  part of  its margin  deposits with  the
broker. Similarly, in the event of the bankruptcy of the writer of an OTC option
purchased  by the Fund, the Fund  could experience a loss of  all or part of the
value of the option. Transactions are entered into by the Fund only with brokers
or financial institutions deemed creditworthy by the Investment Manager.
 
    Each of  the Exchanges  has established  limitations governing  the  maximum
number  of  call or  put  options on  the  same underlying  security  or futures
contract (whether or  not covered) which  may be written  by a single  investor,
whether  acting  alone or  in concert  with others  (regardless of  whether such
options are written on the same or different Exchanges or are held or written on
one or more accounts or through one or more brokers). An Exchange may order  the
liquidation  of positions found  to be in  violation of these  limits and it may
impose other sanctions or restrictions.  These position limits may restrict  the
number of listed options which the Fund may write.
 
    While the futures contracts and options transactions to be engaged in by the
Fund  for  the  purpose  of  hedging the  Fund's  portfolio  securities  are not
speculative in nature, there are risks inherent in the use of such  instruments.
One  such risk which may arise in employing futures contracts to protect against
the price volatility of  portfolio securities is that  the prices of  securities
and  indexes  subject to  futures contracts  (and  thereby the  futures contract
prices) may correlate imperfectly  with the behavior of  the cash prices of  the
Fund's  portfolio securities. Another such risk  is that prices of interest rate
futures contracts may not move in tandem with the changes in prevailing interest
rates against which the Fund
 
                                       23
<PAGE>
seeks a hedge. A correlation may also 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.
 
    The  hours of trading for options may  not conform to the hours during which
the underlying securities  are traded.  To the  extent that  the option  markets
close  before the markets  for the underlying  securities, significant price and
rate movements can take place in the underlying markets that cannot be reflected
in the option markets.
 
    STOCK INDEX OPTIONS.   Options on  stock indexes are  similar to options  on
stock  except that, rather than the right to take or make delivery of stock at a
specified price,  an option  on a  stock index  gives the  holder the  right  to
receive,  upon exercise of the option, an amount of cash if the closing level of
the stock index upon which the option is based is greater than, in the case of a
call, or less than, in the case of a put, the exercise price of the option. This
amount of cash  is equal to  such difference  between the closing  price of  the
index  and  the  exercise price  of  the  option expressed  in  dollars  times a
specified multiple  (the  "multiplier").  The multiplier  for  an  index  option
performs  a  function similar  to the  unit of  trading for  a stock  option. It
determines the total dollar value per  contract of each point in the  difference
between  the exercise price of an option and the current level of the underlying
index. A multiplier of  100 means that a  one-point difference will yield  $100.
Options  on different indexes may have  different multipliers. The writer of the
option is obligated,  in return for  the premium received,  to make delivery  of
this  amount. Unlike stock  options, all settlements  are in cash  and a gain or
loss depends  on  price  movements  in  the stock  market  generally  (or  in  a
particular  segment of the market) rather than the price movements in individual
stocks. Currently, options are traded on the Standard & Poor's 100 Index and the
Standard & Poor's  500 Index on  the Chicago Board  Options Exchange, the  Major
Market  Index and  the Computer  Technology Index,  Oil Index  and Institutional
Index on the American Stock Exchange and  the NYSE Index and NYSE Beta Index  on
the  New York Stock Exchange, The Financial  News Composite Index on the Pacific
Stock Exchange and  the Value  Line Index,  National O-T-C  Index and  Utilities
Index on the Philadelphia Stock Exchange, each of which and any similar index on
which options are traded in the future which include stocks that are not limited
to any particular industry or segment of the market is referred to as a "broadly
based  stock market  index." Options  on stock indexes  provide the  Fund with a
means of protecting the Fund against the risk of market wide price movements. If
the Investment Manager anticipates a market  decline, the Fund could purchase  a
stock  index  put  option.  If the  expected  market  decline  materialized, the
resulting decrease in the value of the  Fund's portfolio would be offset to  the
extent of the increase in the value of the put option. If the Investment Manager
anticipates  a market rise, the  Fund may purchase a  stock index call option to
enable the Fund  to participate  in such  rise until  completion of  anticipated
common  stock purchases by the Fund. Purchases  and sales of stock index options
also enable  the Investment  Manager to  more speedily  achieve changes  in  the
Fund's equity positions.
 
   
    The  Fund will write put options on stock indexes only if such positions are
covered by cash, U.S. Government securities or other liquid portfolio securities
equal to the aggregate exercise price of  the puts, which cover is held for  the
Fund in a segregated account maintained for it by the Fund's Custodian. All call
options  on  stock indexes  written  by the  Fund will  be  covered either  by a
portfolio  of  stocks  substantially  replicating  the  movement  of  the  index
underlying  the call  option or by  holding a  separate call option  on the same
stock index with  a strike price  no higher than  the strike price  of the  call
option sold by the Fund.
    
 
    RISKS  OF OPTIONS ON INDEXES.  Because  exercises of stock index options are
settled in cash, call  writers such as  the Fund cannot  provide in advance  for
their  potential settlement obligations by  acquiring and holding the underlying
securities. A call writer can offset some of the risk of its writing position by
holding a  diversified  portfolio  of  stocks similar  to  those  on  which  the
underlying  index  is  based. However,  most  investors cannot,  as  a practical
matter, acquire and hold a portfolio  containing exactly the same stocks as  the
underlying index, and, as a result, bear a risk that the value of the securities
held  will vary from the value of the  index. Even if an index call writer could
assemble a stock portfolio that exactly
 
                                       24
<PAGE>
reproduced the composition of the underlying  index, the writer still would  not
be fully covered from a risk standpoint because of the "timing risk" inherent in
writing  index options. When  an index option  is exercised, the  amount of cash
that the holder is entitled to  receive is determined by the difference  between
the  exercise price and the  closing index level on the  date when the option is
exercised. As with other kinds of options, the writer will not learn that it has
been assigned until the next business day, at the earliest. The time lag between
exercise and notice of assignment poses no risk for the writer of a covered call
on a specific  underlying security, such  as a common  stock, because there  the
writer's  obligation is to deliver the underlying security, not to pay its value
as of  a  fixed time  in  the past.  So  long as  the  writer already  owns  the
underlying  security,  it  can  satisfy  its  settlement  obligations  by simply
delivering it, and the risk that its value may have declined since the  exercise
date  is borne by the  exercising holder. In contrast, even  if the writer of an
index call holds  stocks that exactly  match the composition  of the  underlying
index,  it will not be able to  satisfy its assignment obligations by delivering
those stocks against payment of the exercise price. Instead, it will be required
to pay cash in an amount based on the closing index value on the exercise  date;
and  by  the time  it  learns that  it  has been  assigned,  the index  may have
declined, with a  corresponding decrease in  the value of  its stock  portfolio.
This  "timing  risk" is  an inherent  limitation  on the  ability of  index call
writers to cover their risk exposure by holding stock positions.
 
    A holder of an index option who exercises it before the closing index  value
for  that day is available runs the risk  that the level of the underlying index
may subsequently change. If  such a change causes  the exercised option to  fall
out-of-the-money,  the exercising holder will be  required to pay the difference
between the closing index value and the exercise price of the option (times  the
applicable multiplier) to the assigned writer.
 
    If dissemination of the current level of an underlying index is interrupted,
or  if trading is interrupted in stocks  accounting for a substantial portion of
the value of an index, the trading  of options on that index will ordinarily  be
halted.  If the trading of options on an underlying index is halted, an exchange
may impose restrictions prohibiting the exercise of such options.
 
    FUTURES CONTRACTS.  The Fund may  purchase and sell interest rate and  stock
index  futures  contracts  ("futures contracts")  that  are traded  on  U.S. and
foreign commodity  exchanges  on such  underlying  securities as  U.S.  Treasury
bonds, notes and bills ("interest rate" futures), on the U.S. dollar and foreign
currencies,  and such indexes as the S&P 500 Index, the Moody's Investment-Grade
Corporate Bond Index and  the New York Stock  Exchange Composite Index  ("index"
futures).
 
    As  a  futures contract  purchaser, the  Fund incurs  an obligation  to take
delivery of a specified  amount of the obligation  underlying the contract at  a
specified  time in the  future for a specified  price. As a  seller of a futures
contract, the Fund incurs an obligation  to deliver the specified amount of  the
underlying obligation at a specified time in return for an agreed upon price.
 
    The  Fund will  purchase or  sell interest  rate futures  contracts and bond
index futures contracts for  the purpose of  hedging its fixed-income  portfolio
(or  anticipated portfolio)  securities against  changes in  prevailing interest
rates. If the Investment Manager anticipates  that interest rates may rise  and,
concomitantly,  the price of fixed-income securities  fall, the Fund may sell an
interest rate futures contract  or a bond index  futures contract. If  declining
interest  rates are anticipated, the Fund  may purchase an interest rate futures
contract to protect against a potential increase in the price of U.S. Government
securities the Fund intends to purchase. Subsequently, appropriate  fixed-income
securities may be purchased by the Fund in an orderly fashion; as securities are
purchased,  corresponding futures  positions would  be terminated  by offsetting
sales of contracts.
 
    The Fund will purchase or sell futures  contracts on the U.S. dollar and  on
foreign  currencies to hedge against an anticipated rise or decline in the value
of the U.S. dollar or foreign currency in which a portfolio security of the Fund
is denominated vis-a-vis another currency.
 
    The Fund will purchase or sell stock index futures contracts for the purpose
of hedging its  equity portfolio (or  anticipated portfolio) securities  against
changes in their prices. If the Investment Manager
 
                                       25
<PAGE>
anticipates  that the prices  of stock held by  the Fund may  fall, the Fund may
sell a  stock index  futures  contract. Conversely,  if the  Investment  Manager
wishes  to hedge against anticipated price rises  in those stocks which the Fund
intends to purchase,  the Fund may  purchase stock index  futures contracts.  In
addition, interest rate and stock index futures contracts will be bought or sold
in  order  to close  out a  short or  long position  in a  corresponding futures
contract.
 
    Although most interest rate  futures contracts call  for actual delivery  or
acceptance  of  securities,  the contracts  usually  are closed  out  before the
settlement date  without  the  making  or  taking  of  delivery.  Index  futures
contracts  provide for the  delivery of an  amount of cash  equal to a specified
dollar amount times the difference between the stock index value at the open  or
close  of the last trading day of the contract and the futures contract price. A
futures contract sale is closed out by effecting a futures contract purchase for
the same aggregate amount of the specific  type of equity security and the  same
delivery  date. If  the sale  price exceeds  the offsetting  purchase price, the
seller would be paid the difference and would realize a gain. If the  offsetting
purchase  price exceeds the sale price, the  seller would pay the difference and
would realize a loss.  Similarly, a futures contract  purchase is closed out  by
effecting  a futures contract sale for the same aggregate amount of the specific
type of equity security and the same delivery date. If the offsetting sale price
exceeds the purchase price, the purchaser  would realize a gain, whereas if  the
purchase  price exceeds the offsetting sale price, the purchaser would realize a
loss. There is no assurance that the Fund  will be able to enter into a  closing
transaction.
 
   
    INTEREST RATE FUTURES CONTRACTS.  When the Fund enters into an interest rate
futures contract, it is initially required to deposit with the Fund's Custodian,
in a segregated account in the name of the broker performing the transaction, an
"initial margin" of cash or U.S. Government securities or other liquid portfolio
securities  equal to  approximately 2%  of the  contract amount.  Initial margin
requirements are established by the  Exchanges on which futures contracts  trade
and may, from time to time, change.
In  addition, brokers  may establish  margin deposit  requirements in  excess of
those required by the Exchanges.
    
 
    Initial  margin  in  futures  transactions  is  different  from  margin   in
securities transactions in that initial margin does not involve the borrowing of
funds  by a brokers' client but is, rather,  a good faith deposit on the futures
contract which will be returned to the  Fund upon the proper termination of  the
futures  contract. The margin deposits  made are marked to  market daily and the
Fund may be required to make subsequent deposits called "variation margin", with
the Fund's  Custodian, in  the account  in the  name of  the broker,  which  are
reflective  of price fluctuations  in the futures  contract. Currently, interest
rates 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, GNMA Certificates and Bank Certificates of Deposit.
 
    INDEX FUTURES CONTRACTS.  The Fund may invest in index futures contracts. An
index futures contract  sale creates an  obligation by the  Fund, as seller,  to
deliver  cash at  a specified  future time.  An index  futures contract purchase
would create an obligation by the Fund,  as purchaser, to take delivery of  cash
at  a specified  future time.  Futures contracts on  indexes do  not require the
physical delivery of securities, but provide for a final cash settlement on  the
expiration  date  which  reflects  accumulated profits  and  losses  credited or
debited to each party's account.
 
    The Fund  is  required to  maintain  margin deposits  with  brokerage  firms
through  which it effects  index futures contracts  in a manner  similar to that
described above  for interest  rate futures  contracts. Currently,  the  initial
margin requirement is approximately 5% of the contract amount for index futures.
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.
 
    At any time prior to expiration of the futures contract, the Fund may  elect
to  close the  position by  taking an  opposite position  which will  operate to
terminate the Fund's position in the futures contract. A final determination  of
variation  margin is  then made, additional  cash is  required to be  paid by or
released to the Fund and the Fund realizes a loss or a gain.
 
                                       26
<PAGE>
    Currently, index futures contracts can be purchased or sold with respect to,
among others, the Standard  & Poor's 500  Stock Price Index  and the Standard  &
Poor's  100 Stock Price Index  on the Chicago Mercantile  Exchange, the New York
Stock Exchange  Composite Index  on the  New York  Futures Exchange,  the  Major
Market  Index  on  the  American Stock  Exchange,  the  Moody's Investment-Grade
Corporate Bond Index  on the Chicago  Board of  Trade and the  Value Line  Stock
Index on the Kansas City Board of Trade.
 
    OPTIONS  ON FUTURES CONTRACTS.  The Fund may purchase and write call and put
options on futures contracts and enter into closing transactions with respect to
such options to terminate an existing position. An option on a futures  contract
gives  the purchaser the right (in return  for the premium paid), and the writer
the obligation, to assume a position in  a futures contract (a long position  if
the option is a call and a short position if the option is a put) at a specified
exercise  price at any time during the term  of the option. Upon exercise of the
option, the delivery of the futures position by the writer of the option to  the
holder  of the option is  accompanied by delivery of  the accumulated balance in
the writer's futures margin  account, which represents the  amount by which  the
market  price of the  futures contract at  the time of  exercise exceeds, in the
case of a call, or is less than, in the case of a put, the exercise price of the
option on the futures contract.
 
    The Fund will purchase and write options on futures contracts for  identical
purposes  to  those set  forth  above for  the  purchase of  a  futures contract
(purchase of a call option or  sale of a put option)  and the sale of a  futures
contract  (purchase of a put option or sale of a call option), or to close out a
long or short  position in futures  contracts. If, for  example, the  Investment
Manager  wished  to  protect  against  an increase  in  interest  rates  and the
resulting negative  impact  on  the  value of  a  portion  of  its  fixed-income
portfolio,  it might write a  call option on an  interest rate futures contract,
the underlying security of  which correlates with the  portion of the  portfolio
the  Investment Manager seeks to hedge. Any  premiums received in the writing of
options on futures  contracts may, of  course, augment the  total return of  the
Fund  and thereby  provide a further  hedge against losses  resulting from price
declines in portions of the Fund's portfolio.
 
    The writer of an option on a futures contract is required to deposit initial
and variation margin  pursuant to  requirements similar to  those applicable  to
futures  contracts. Premiums received from the writing of an option on a futures
contract are included in initial margin deposits.
 
    LIMITATIONS ON FUTURES CONTRACTS AND OPTIONS  ON FUTURES.  The Fund may  not
enter into futures contracts or purchase related options thereon if, immediately
thereafter, the amount committed to margin plus the amount paid for premiums for
unexpired  options on futures  contracts exceeds 5%  of the value  of the Fund's
total assets, after taking into  account unrealized gains and unrealized  losses
on such contracts it has entered into, provided, however, that in the case of an
option that is in-the-money (the exercise price of the call (put) option is less
(more)  than  the  market price  of  the  underlying security)  at  the  time of
purchase, the  in-the-money  amount  may  be excluded  in  calculating  the  5%.
However,  there is no overall limitation on  the percentage of the Fund's assets
which may be subject to  a hedge position. In  addition, in accordance with  the
regulations of the Commodity Futures Trading Commission ("CFTC") under which the
Fund  is exempted from registration  as a commodity pool  operator, the Fund may
only enter into futures contracts and options on futures contracts  transactions
for  purposes of hedging a part or all of its portfolio. If the CFTC changes its
regulations so that  the Fund  would be permitted  to write  options on  futures
contracts  for purposes other  than hedging the  Fund's investments without CFTC
registration, the  Fund may  engage  in such  transactions for  those  purposes.
Except  as described above, there are no other limitations on the use of futures
and options thereon by the Fund.
 
    RISKS OF TRANSACTIONS IN  FUTURES CONTRACTS AND RELATED  OPTIONS.  The  Fund
may  sell a  futures contract  to protect  against the  decline in  the value of
securities held by the Fund. However, it is possible that the futures market may
advance and  the value  of securities  held in  the portfolio  of the  Fund  may
decline. If this occurred, the Fund would lose money on the futures contract and
also experience a
 
                                       27
<PAGE>
decline  in value of  its portfolio securities. However,  while this could occur
for a very brief  period or to  a very small  degree, over time  the value of  a
diversified  portfolio will tend  to move in  the same direction  as the futures
contracts.
 
    If the Fund purchases  a futures contract to  hedge against the increase  in
value  of  securities  it intends  to  buy,  and the  value  of  such securities
decreases, then  the Fund  may determine  not  to invest  in the  securities  as
planned  and will realize a loss on the futures contract that is not offset by a
reduction in the price of the securities.
 
   
    In addition, if the Fund holds a long position in a futures contract or  has
sold  a put  option on a  futures contract,  it will hold  cash, U.S. Government
securities or other liquid portfolio securities  equal to the purchase price  of
the contract or the exercise price of the put option (less the amount of initial
or  variation margin on deposit) in a segregated account maintained for the Fund
by its  Custodian. Alternatively,  the Fund  could cover  its long  position  by
purchasing  a put option on the same  futures contract with an exercise price as
high or higher than the price of the contract held by the Fund.
    
 
   
    If the Fund maintains a short position  in a futures contract or has sold  a
call  option on a futures contract, it will cover this position by holding, in a
segregated account maintained at its Custodian, cash, U.S. Government securities
or other liquid portfolio securities equal  in value (when added to any  initial
or variation margin on deposit) to the market value of the securities underlying
the  futures contract or the  exercise price of the  option. Such a position may
also be covered by owning the securities underlying the futures contract (in the
case of a stock index futures  contract a portfolio of securities  substantially
replicating the relevant index), or by holding a call option permitting the Fund
to  purchase the same contract at a price  no higher than the price at which the
short position was established.
    
 
    Exchanges may limit the amount by  which the price of futures contracts  may
move  on any day. If  the price moves equal the  daily limit on successive days,
then it may  prove impossible to  liquidate a futures  position until the  daily
limit moves have ceased.
 
    The  extent to which the Fund  may enter into transactions involving options
and futures contracts may be limited by the Internal Revenue Code's requirements
for qualification as a regulated investment company and the Fund's intention  to
qualify  as such. See "Dividends, Distributions and Taxes" in the Prospectus and
the Statement of Additional Information.
 
    There may  exist an  imperfect correlation  between the  price movements  of
futures  contracts purchased by the Fund and  the movements in the prices of the
securities which are the  subject of the hedge.  If participants in the  futures
market elect to close out their contracts through offsetting transactions rather
than  meet margin deposit  requirements, distortions in  the normal relationship
between the debt securities and futures markets could result. Price  distortions
could also result if investors in futures contracts opt to make or take delivery
of  underlying securities rather than engage  in closing transactions due to the
resultant reduction in the liquidity of the futures market. In addition, due  to
the  fact that, from the point of  view of speculators, the deposit requirements
in the futures  markets are less  onerous than margin  requirements in the  cash
market, increased participation by speculators in the futures market could cause
temporary  price distortions. Due to the possibility of price distortions in the
futures market and because of the imperfect correlation between movements in the
prices of securities and movements in the prices of futures contracts, a correct
forecast of interest rate trends by the Investment Manager may still not  result
in a successful hedging transaction.
 
    There  is no assurance that a liquid secondary market will exist for futures
contracts and related  options in  which the  Fund may  invest. In  the event  a
liquid  market does  not exist, it  may not be  possible to close  out a futures
position, and in the event of  adverse price movements, the Fund would  continue
to  be required to  make daily cash  payments of variation  margin. In addition,
limitations imposed by an exchange or board of trade on which futures  contracts
are  traded may compel or prevent the Fund from closing out a contract which may
result in reduced gain or  increased loss to the Fund.  The absence of a  liquid
market in futures contracts might cause the Fund to make or take delivery of the
underlying securities at a time when it may be disadvantageous to do so.
 
                                       28
<PAGE>
    Compared  to the purchase or sale of futures contracts, the purchase of call
or put options  on futures contracts  involves less potential  risk to the  Fund
because  the maximum amount  at risk is  the premium paid  for the options (plus
transaction costs). However, there may be  circumstances when the purchase of  a
call  or put option  on a futures  contract would result  in a loss  to the Fund
notwithstanding that the purchase or sale of a futures contract would not result
in a loss, as in the  instance where there is no  movement in the prices of  the
futures contract or underlying securities.
 
    The  Investment  Manager  has  substantial  experience  in  the  use  of the
investment techniques described  above under  the heading  "Options and  Futures
Transactions,"  which techniques require  skills different from  those needed to
select  the  portfolio  securities   underlying  various  options  and   futures
contracts.
 
PORTFOLIO TURNOVER
 
   
    It  is anticipated that  the Fund's portfolio turnover  rate will not exceed
200%. A 200% turnover rate would occur,  for example, if 200% 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.
During  the fiscal  years ended March  31, 1996  and March 31,  1997, the Fund's
portfolio turnover rates were 69% and 42%, respectively.
    
 
INVESTMENT RESTRICTIONS
- --------------------------------------------------------------------------------
 
    In addition to the investment restrictions enumerated in the Prospectus, the
investment  restrictions  listed  below  have  been  adopted  by  the  Fund   as
fundamental   policies,  except  as  otherwise   indicated.  Under  the  Act,  a
fundamental policy may  not be changed  without the  vote of 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% or more of the shares present at  a
meeting  of shareholders, if the holders of 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.
 
    The Fund may not:
 
         1. Purchase or sell real estate or interests therein, although the Fund
    may purchase securities of  issuers which engage  in real estate  operations
    and securities secured by real estate or interests therein.
 
         2.  Purchase  oil,  gas  or other  mineral  leases,  rights  or royalty
    contracts or exploration or development  programs, except that the Fund  may
    invest  in the securities of companies  which operate, invest in, or sponsor
    such programs.
 
         3. 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 its  total assets  (not including  the
    amount borrowed).
 
         4.  Pledge its  assets or assign  or otherwise encumber  them except to
    secure borrowings effected within the  limitations set forth in  restriction
    (3).  For  the purpose  of  this restriction,  collateral  arrangements with
    respect to the writing of  options and collateral arrangements with  respect
    to  initial or variation margin for futures  are not deemed to be pledges of
    assets.
 
         5. 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 or reverse repurchase agreement; (b) purchasing
    any securities on a when-issued or delayed delivery basis; (c) purchasing or
    selling  futures contracts,  forward foreign exchange  contracts or options;
    (d) borrowing money in accordance with restrictions described above; or  (e)
    lending portfolio securities.
 
                                       29
<PAGE>
         6.  Make loans of money  or securities, except: (a)  by the purchase of
    publicly  distributed  debt  obligations  in  which  the  Fund  may   invest
    consistent  with its investment objective and policies; (b) by investment in
    repurchase agreements; or (c) by lending its portfolio securities.
 
         7. Make short sales of securities.
 
         8. Purchase securities on margin,  except for such short-term loans  as
    are  necessary for  the clearance  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.
 
         9. 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.
 
        10.  Invest for the  purpose of exercising control  or management of any
    other issuer.
 
        11.  Purchase  securities  of  other  investment  companies,  except  in
    connection  with a  merger, consolidation, reorganization  or acquisition of
    assets or in accordance with the provisions of Section 12(d) of the Act  and
    any Rules promulgated thereunder.
 
   
        12.  Purchase or sell  commodities or commodities  contracts except that
    the Fund may purchase or sell futures contracts or options on futures.
    
 
   
    Notwithstanding any other  investment policy  or restriction,  the Fund  may
seek  to achieve its investment objective  by investing all or substantially all
of its  assets  in another  investment  company having  substantially  the  same
investment objective as the Fund.
    
 
    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.
 
PORTFOLIO TRANSACTIONS AND BROKERAGE
- --------------------------------------------------------------------------------
 
   
    Subject  to the general supervision of  the Trustees, the Investment Manager
is responsible  for decisions  to buy  and  sell securities  for the  Fund,  the
selection of brokers and dealers to effect the transactions, and the negotiation
of  brokerage commissions, if any. Purchases and  sales of securities on a stock
exchange are  effected  through  brokers  who  charge  a  commission  for  their
services.  The Fund expects that the primary  market for the securities in which
it intends  to invest  will generally  be the  over-the-counter market.  In  the
over-the-counter  market, securities are generally traded  on a "net" basis with
dealers acting as principal for their own accounts without a stated  commission,
although  the price of the security usually includes a profit to the dealer. The
Fund 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.  Options and  futures
transactions  will usually be effected through a broker and a commission will be
charged.  On  occasion,  the  Fund  may  also  purchase  certain  money   market
instruments  directly from an issuer, in  which case no commissions or discounts
are paid. For the fiscal period June 2, 1994 through March 31, 1995 and for  the
fiscal  years ended March 31, 1996 and March  31, 1997, the Fund paid a total of
$19,845, $71,918 and $46,074, respectively, in brokerage commissions.
    
 
   
    The Investment Manager currently serves as investment manager to a number of
clients, including other  investment companies,  and may  in the  future act  as
investment  manager or adviser to  others. It is the  practice of the Investment
Manager to cause purchase and sale  transactions to be allocated among the  Fund
and  others whose  assets it manages  in such  manner as it  deems equitable. In
making such  allocations  among the  Fund  and other  client  accounts,  various
factors  may be considered  including the respective  investment objectives, the
relative size of portfolio  holdings of the same  or comparable securities,  the
availability  of  cash  for  investment,  the  size  of  investment  commitments
generally held and  the opinions  of the  persons responsible  for managing  the
portfolios of the Fund and other client
    
 
                                       30

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  will be  given to  obtaining the most
favorable prices and efficient executions of transactions. Consistent with  this
policy,  when  securities transactions  are effected  on  a stock  exchange, the
Fund's policy is  to pay commissions  which are considered  fair and  reasonable
without necessarily determining that the lowest possible commissions are paid in
all  circumstances.  The Fund  believes that  a requirement  always to  seek the
lowest possible commission cost could impede effective portfolio management  and
preclude  the Fund and the  Investment Manager from obtaining  a high quality of
brokerage and research services. In  seeking to determine the reasonableness  of
brokerage  commissions paid  in any  transaction, the  Investment Manager relies
upon its experience  and knowledge  regarding commissions  generally charged  by
various  brokers and  on its judgment  in evaluating the  brokerage and research
services received from the broker effecting the transaction. Such determinations
are necessarily subjective  and imprecise,  and in  most cases  an exact  dollar
value for those services is not ascertainable.
 
    The  Fund  anticipates that  certain of  its transactions  involving foreign
securities will be effected on  foreign securities exchanges. Fixed  commissions
on  such  transactions  are  generally  higher  than  negotiated  commissions on
domestic transactions. There is also  generally less government supervision  and
regulation  of  foreign  securities exchanges  and  brokers than  in  the United
States.
 
    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  prices and executions are
obtainable from more  than one broker  or dealer, it  may give consideration  to
placing  portfolio transactions with those brokers  and dealers who also furnish
research and other services to the Fund or the Investment Manager. Such services
may include,  but  are  not limited  to,  any  one or  more  of  the  following:
information  as  to  the  availability  of  securities  for  purchase  or  sale;
statistical or factual  information or opinions  pertaining to investment;  wire
services; and appraisals or evaluations of portfolio securities.
 
   
    The information and services received by the Investment Manager from brokers
and  dealers may be  of benefit to  the Investment Manager  in the management of
accounts of some of its other clients and may not in all cases benefit the  Fund
directly.  While  the receipt  of  such information  and  services is  useful in
varying degrees and would  generally reduce the amount  of research or  services
otherwise  performed by the Investment Manager  and thereby reduce its expenses,
it is of  indeterminable value  and the management  fee paid  to the  Investment
Manager  is not reduced by  any amount that may be  attributable to the value of
such services. For the fiscal year ended March 31, 1997, the Fund did not direct
the payment of any brokerage commissions to brokers because of research services
provided.
    
 
   
    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. During the  fiscal year ended March  31, 1997, the Fund did
not effect any principal transactions with DWR.
    
 
    Consistent with  the  policy  described  above,  brokerage  transactions  in
securities listed on exchanges or admitted to unlisted trading privileges may be
effected  through DWR. In order for DWR to effect any 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
 
                                       31
<PAGE>
commensurate arm's-length transaction. Furthermore, the Board of Trustees of the
Fund,  including a majority of the Trustees  who are not "interested" persons of
the Fund, as defined  in the Act, have  adopted procedures which are  reasonably
designed to provide that any commissions, fees or other remuneration paid to DWR
are  consistent  with  the foregoing  standard.  The  Fund does  not  reduce the
management fee it pays to the Investment Manager by any amount of the  brokerage
commissions it may pay to DWR.
 
PURCHASE OF FUND SHARES
- --------------------------------------------------------------------------------
 
   
    As  discussed in the Prospectus, shares of  the Fund are distributed by Dean
Witter Distributors Inc. (the "Distributor"). The Distributor has entered into a
dealer agreement with DWR, which through its own sales organization sells shares
of the Fund. In addition, the  Distributor may enter into agreements with  other
selected  dealers  ("Selected  Broker-Dealers").  The  Distributor,  a  Delaware
corporation, is an indirect  wholly-owned subsidiary of  MSDWD. The Trustees  of
the  Fund, 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"), approved, at their meeting held on April 24, 1997, the
current Distribution  Agreement (the  "Distribution Agreement")  appointing  the
Distributor  exclusive distributor  of the Fund's  shares and  providing for the
Distributor to bear distribution expenses not  borne by the Fund. By its  terms,
the  Distribution Agreement has an  initial term ending April  30, 1998 and will
remain in effect  from year to  year thereafter  if approved by  the Board.  The
current Distribution Agreement took effect on May 31, 1997 upon the consummation
of  the merger of Dean Witter, Discover & Co. with Morgan Stanley Group Inc. and
is substantially identical to the Fund's previous distribution agreement  except
for its dates of effectiveness and termination.
    
 
    The  Distributor bears all expenses it may incur 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.  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 it or  any selected dealer
provides and for  the expenses it  bears 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 0.80% 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 Fund's average daily  net assets. The Distributor  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   received
approximately $160,000, $655,000 and $1,408,132,
    
 
                                       32
<PAGE>
   
respectively  in contingent deferred  sales charges for the  period June 2, 1994
through March 31, 1995 and for the  fiscal years ended March 31, 1996 and  March
31, 1997, none of which was retained by the Distributor.
    
 
    The  Distributor has informed the Fund that an amount of the fees payable by
the Fund each year pursuant  to the Plan of Distribution  equal to 0.20% of  the
Fund's  average daily net assets  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. At their meeting held on  October 26, 1995, the Directors of  the
Fund, including all of the independent 12b-1 Directors, 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.
 
    The  Plan was adopted by a vote of the Trustees of the Fund on May 10, 1994,
at a meeting of the Trustees called for the purpose of voting on such Plan.  The
vote  included the vote  of a majority 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").  In making  their decision  to adopt  the Plan,  the  Trustees
requested  from the  Distributor and  received such  information as  they deemed
necessary to make an informed determination as to whether or not adoption of the
Plan was  in the  best interests  of the  shareholders of  the Fund.  After  due
consideration   of  the  information  received,   the  Trustees,  including  the
Independent 12b-1 Trustees, determined that  adoption of the Plan would  benefit
the  shareholders of the Fund. InterCapital, as the then sole shareholder of the
Fund, approved the Plan on May 10, 1994, whereupon the Plan went into effect.
 
   
    Under the Plan and as required by Rule 12b-1, the Trustees will receive  and
review  promptly after the end of each  fiscal quarter a written report provided
by the Distributor of the amounts expended by the Distributor under the Plan and
the purpose for  which such  expenditures were  made. The  Fund accrued  amounts
payable  to the Distributor under  the Plan, during the  fiscal year ended March
31, 1997, of $6,228,452. This  amount is equal to  payments required to be  paid
monthly  by the  Fund which  were computed at  the annual  rate of  0.80% of the
average daily net assets of  the Fund for the  fiscal period 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 five years after their purchase.  DWR compensates its account executives  by
paying  them, from its own funds, commissions for the sale of the Fund's shares,
currently a gross  sales credit of  up to 4%  of the amount  sold and an  annual
residual  commission of  up to 0.20  of 1%  of the current  value (not including
reinvested dividends  or distributions)  of  the amount  sold. The  gross  sales
credit  is  a charge  which  reflects commissions  paid  by DWR  to  its 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 opportunity costs, such as the gross sales credit and  an
assumed interest charge thereon ("carrying charge"). In the
 
                                       33
<PAGE>
Distributor's  reporting of the 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 $6,228,452  accrued under the  Plan for the year
ended March 31, 1997 to the  Distributor. The Distributor and DWR estimate  that
they  have spent, pursuant to the Plan,  $40,579,469 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) 4.59%  ($1,863,204) --  advertising and
promotional  expenses;  (ii)  0.31%  ($125,929)  printing  of  prospectuses  for
distribution  to other than current shareholders; and (iii) 95.10% ($38,590,336)
- -- other expenses, including the gross sales credit and the carrying charge,  of
which  3.72%  ($1,434,274)  represents  carrying  charges,  38.66% ($14,918,159)
represents commission credits to DWR branch offices for payments of  commissions
to  account executives  and 57.62%  ($22,237,903) represents  overhead and other
branch office distribution-related expenses.
    
 
   
    At any given time, the  expenses of distributing shares  of the Fund 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
the  excess expenses, including the carrying  charge designed to approximate the
opportunity costs incurred  by DWR 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 $28,870,822 as  of March 31, 1997.  Because
there  is no requirement under  the Plan that the  Distributor be reimbursed for
all distribution 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 distribution  expenses
in  excess  of payments  made  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,  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 or indirect
financial interest in the operation  of the Plan except  to the extent that  the
Distributor,  InterCapital, DWR or  certain of their 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.
 
   
    Under its terms, the Plan remained in  effect until April 30, 1995 and  will
continue  from year  to year thereafter,  provided such  continuance is approved
annually by a  vote of  the Trustees  in the  manner described  above. The  most
recent  continuance of the Plan for one year, until April 30, 1998, 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  24, 1997. Prior to approving
the continuation  of the  Plan, the  Trustees requested  and received  from  the
Distributor  and reviewed  all the  information which  they 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  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. In the Trustees'  quarterly review of the Plan, they
will consider  its  continued  appropriateness and  the  level  of  compensation
provided herein.
    
 
                                       34
<PAGE>
    The  Plan may not be  amended to increase materially  the amount to be spent
for the services described therein without  approval of the shareholders of  the
Fund,  and all  material amendments  of 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 Trustees shall be  committed to the discretion of  the
Independent Trustees.
 
DETERMINATION OF NET ASSET VALUE
 
    As stated in the Prospectus, short-term securities with remaining maturities
of  60 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.  Other   short-term  debt   securities  will  be   valued  on   a
mark-to-market  basis until such time  as they reach a  remaining maturity of 60
days, whereupon they will be valued at  amortized cost using their value on  the
61st  day 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. 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 latest bid  and asked prices.  Unlisted options on  debt
securities  and all options on equity securities  are valued at the mean between
their latest bid and asked prices. Futures  are valued at the latest sale  price
on  the commodities exchange  on which they trade  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
and other assets  are valued at  their fair  value as determined  in good  faith
under procedures established by and under the supervision of the Trustees.
 
    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 4:00  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 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.
 
    Generally, trading in foreign securities, as well as corporate bonds, United
States government  securities and  money  market instruments,  is  substantially
completed  each day at  various times prior to  the close of  the New York Stock
Exchange. The values of such securities used in computing the net asset value of
the Fund's shares  are determined as  of such times.  Foreign currency  exchange
rates  are also generally  determined prior to  the close of  the New York Stock
Exchange. Occasionally, events which  affect the values  of such securities  and
such exchange rates may occur between the times at which they are determined and
the  close of the New York Stock Exchange and will therefore not be reflected in
the computation of the  Fund's net asset value.  If events materially  affecting
the  value of  such securities occur  during such period,  then these securities
will be valued at their fair value as determined in good faith under  procedures
established by and under the supervision of the 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 Dean Witter
Trust Company (the "Transfer  Agent"). This is an  open account in which  shares
owned  by the investor are credited by the Transfer Agent in lieu of issuance of
a share certificate. If a share certificate is desired, it must be requested  in
writing  for each transaction. Certificates are  issued only for full shares and
may be  redeposited in  the account  at  any time.  There is  no charge  to  the
investor  for  issuance  of  a certificate.  Whenever  a  shareholder instituted
transaction takes place in the  Shareholder Investment Account, the  shareholder
will  be mailed a confirmation  of the transaction from the  Fund or from DWR or
other selected broker-dealer.
 
                                       35
<PAGE>
    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 record
date. 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  charge,
such  request should be  received by the  Transfer Agent at  least five business
days prior to the record  date of the dividend or  distribution. 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 the  Distributor,
which  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 a Dean Witter  Fund other than Dean  Witter
High  Income Securities.  Such investment  will be  made as  described above for
automatic investment in shares in shares of the Fund, at the net asset value per
share of  the selected  Dean Witter  Fund as  of the  close of  business on  the
payment  date of the dividend or  distribution. Shareholders of Dean Witter High
Income Securities  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.  As discussed in
the Prospectus,  any shareholder  who  receives a  cash payment  representing  a
dividend  or distribution  may invest such  dividend or distribution  at the net
asset value next  determined after receipt  by the Transfer  Agent, without  the
imposition  of a contingent deferred sales  charge upon redemption, by returning
the check or the proceeds to the Transfer Agent within 30 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.
 
    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
deferred sales charge)  to the  shareholder will  be the  designated monthly  or
quarterly amount.
 
    The  Transfer Agent acts as an 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
 
                                       36
<PAGE>
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  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 "Redemptions 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 Account Executive or by written nomination to the Transfer Agent.  In
addition,  the party and/or  the address to  which the 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.
 
    DIRECT  INVESTMENTS THROUGH TRANSFER AGENT.  As discussed in the Prospectus,
a shareholder may  make additional  investments in Fund  shares at  any time  by
sending  a check in any amount, not less  than $100, payable to Dean Witter High
Income Securities, 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.
 
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 Intermediate  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  and five Dean Witter Funds which
are money  market funds  (the foregoing  eleven non-CDSC  funds are  hereinafter
referred  to 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.  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.
 
                                       37
<PAGE>
    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 an  Exchange Fund, 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  Fund (calculated  from the  last day  of the  month in  which the
Exchange Fund shares were acquired), the holding period or "year since  purchase
payment made" is frozen. When shares are redeemed out of the Exchange Fund, they
will  be subject  to a CDSC  which would  be based upon  the period  of time the
shareholder held shares in a CDSC fund. However, in the case of shares exchanged
into an Exchange Fund on  or after April 23, 1990,  upon a redemption of  shares
which results in a CDSC being imposed, a credit (not to exceed the amount of the
CDSC)  will be given in an amount  equal to the Exchange Fund 12b-1 distribution
fees, if any, incurred  on or after  that date which  are attributable to  those
shares.  Shareholders  acquiring shares  of an  Exchange  Fund pursuant  to this
exchange privilege may  exchange those  shares back into  a CDSC  fund from  the
Exchange  Fund, with no CDSC being imposed  on such exchange. The holding period
previously frozen when shares  were first exchanged for  shares of the  Exchange
Fund  resumes on the last  day of the month  in which shares of  a 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.
 
    If shares of the Fund are exchanged for shares of another CDSC fund having a
CDSC which  is imposed  at a  higher  rate or  is subject  to a  different  time
schedule  than the CDSC  imposed upon a redemption  of a share  of the Fund, the
higher CDSC will  be imposed  upon redemption of  shares of  the fund  exchanged
into.  Likewise, if shares of another CDSC  fund are exchanged for shares of the
Fund, upon rdemption of shares of the Fund, a CDSC will be imposed in accordance
with the CDSC schedule applicable to the fund with the higher CDSC. Moreover, if
shares of  the  Fund are  exchanged  for shares  of  another CDSC  fund  with  a
different  CDSC schedule imposing  a higher CDSC  and are subsequently exchanged
again for shares of  the Fund, the  higher CDSC will  still apply upon  ultimate
redemption of shares of the Fund.
 
    When  shares initially purchased in a CDSC  fund are exchanged for shares of
another CDSC fund, or for  shares of an Exchange Fund,  the date of purchase  of
the shares of the fund exchanged into, for purposes of the CDSC upon redemption,
will  be the  last day  of the month  in which  the shares  being exchanged were
originally purchased.  In allocating  the purchase  payments between  funds  for
purposes of the CDSC, the amount which represents the current net asset value of
shares  at the time of the exchange which  were (i) purchased more than three or
six years (depending on the CDSC schedule applicable to the shares) prior to the
exchange,  (ii)  originally  acquired  through  reinvestment  of  dividends   or
distributions  and  (iii) acquired  in exchange  for  shares of  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
acquired  prior  to  April  30,  1984, shares  of  Dean  Witter  Dividend Growth
Securities Inc. and  Dean Witter  Natural Resource  Development Securities  Inc.
acquired  prior  to July  2, 1984,  and  shares of  Dean Witter  Strategist Fund
acquired prior to November 8, 1989, are also considered Free Shares and will  be
the  first Free Shares to be exchanged.  After an exchange, all dividends earned
on shares in an Exchange Fund
 
                                       38
<PAGE>
will be considered  Free Shares. If  the exchanged amount  exceeds the value  of
such  Free Shares, an exchange  is made, on a  block-by-block basis, of non-Free
Shares held for  the longest  period of  time (except  that if  shares held  for
identical  periods of time but  subject to different CDSC  schedules are held in
the same Exchange Privilege account, the  shares of that block that are  subject
to  a lower CDSC rate will  be exchanged prior to the  shares of that block that
are subject to  a higher CDSC  rate). Shares  equal to any  appreciation in  the
value  of non-Free  Shares exchanged  will be  treated as  Free Shares,  and the
amount of the purchase  payments for the non-Free  Shares of the fund  exchanged
into  will be equal to the  lesser of (a) the purchase  payments for, or (b) the
current net  asset value  of,  the exchanged  non-Free  Shares. If  an  exchange
between  funds would result  in exchange of  only part of  a particular block of
non-Free Shares, then shares equal to any appreciation in the value of the block
(up to the amount of the exchange) will be treated as Free Shares and  exchanged
first,  and the purchase payment for that block  will be allocated on a pro rata
basis between the non-Free Shares of that block to be retained and the  non-Free
Shares   to  be  exchanged.  The  prorated   amount  of  such  purchase  payment
attributable to the retained non-Free Shares will remain as the purchase payment
for such shares, and the amount  of purchase payment for the exchanged  non-Free
Shares  will be equal to  the lesser of (a) the  prorated amount of the purchase
payment for, or  (b) the current  net asset value  of, those exchanged  non-Free
Shares.  Based upon the 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 California  Tax-Free Daily  Income Trust  and Dean  Witter New York
Municipal Money Market  Trust, although  those funds may,  at their  discretion,
accept  initial  investments of  as  low as  $1,000.  The minimum  investment is
$10,000 for Dean Witter Short-Term U.S.  Treasury Trust, although that fund,  in
its  discretion,  may accept  initial purchases  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 an  Exchange Fund,  the
shares  of  that fund  will  be held  in  a special  Exchange  Privilege Account
separately from accounts of  those shareholders who  have acquired their  shares
directly  from that  fund. As a  result, certain services  normally available to
shareholders of those 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
Exchange  Funds, pursuant to  the 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
 
                                       39
<PAGE>
closed for other than customary weekends and holidays, (b) when trading on  that
Exchange  is  restricted, (c)  when an  emergency  exists as  a result  of which
disposal by the Fund of securities owned by it is not reasonably practicable  or
it  is not reasonably practicable for the  Fund fairly to determine the value of
its net assets,  (d) during any  other period when  the Securities and  Exchange
Commission  by order so permits (provided  that applicable rules and regulations
of the  Securities  and Exchange  Commission  shall  govern as  to  whether  the
conditions prescribed in (b) or (c) exist) or (e) if the Fund would be unable to
invest amounts effectively in accordance with its investment objective, 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  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, 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 certificates, 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") 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 acceptance 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. 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 a means of a new 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  five 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 five
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 five  years.
The CDSC will be paid to the Distributor.
 
                                       40
<PAGE>
    In  determining the applicability  of a 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
last five  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 five 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. Any portion of the amount redeemed which exceeds an amount which
represents both such increase  in value and the  value of shares purchased  more
than  five  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.
 
    In  addition, the CDSC, if otherwise applicable,  will be waived in the case
of: (i) 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  or Custodial  Account under Section  403(b)(7) of  the Internal Revenue
Code, provided in either case that  the redemption is requested within one  year
of  the death  or initial determination  of disability, and  (ii) redemptions in
connection with the  following retirement  plan distributions:  (a) lump-sum  or
other  distributions from a qualified corporate of 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 Individual
Retirement Account or Custodial Account under Section 403(b)(7) of the  Internal
Revenue Code following attainment of age 59 1/2; and (c) a tax-free return of an
excess  contribution to an  IRA. For the purpose  of determining disability, the
Distributor utilizes the definition of disability contained in Section  72(m)(7)
of the Code, which relates to the inability to engage in gainful employment. All
waivers   will  be  granted  only  following   receipt  by  the  Distributor  of
confirmation of the investor's entitlement.
 
    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:

Fifth.......................................................           1.0%
Sixth and thereafter........................................          None
</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 five-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 five
years and amounts equal to the current value of shares purchased more than  five
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
five  years  of  purchase  which  are  in  excess  of  these  amounts  and which
redemptions
 
                                       41
<PAGE>
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 above.
 
    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 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. 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.
 
    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 30 days after the  redemption
or  repurchase, reinstate any portion or all  of the proceeds of such redemption
or repurchase in shares  of the Fund  held by the shareholder  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 and  state 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 and state personal income tax purposes but will be applied to
adjust the cost basis of the shares acquired upon reinstatement.
 
DIVIDENDS, DISTRIBUTIONS AND TAXES
- --------------------------------------------------------------------------------
 
    As discussed in the Prospectus, the Fund will determine either to distribute
or  to retain all  or part of  any net long-term  capital gains in  any year for
reinvestment. If any such gains are  retained, the Fund will pay federal  income
tax  thereon, and  will notify  shareholders that  following an  election by the
Fund, the shareholders will be required  to include such undistributed gains  in
determining  their taxable income and  may claim their share  of the tax paid by
the Fund as a credit against  their individual federal income tax. In  computing
net  investment income, the Fund will  not amortize premiums or accrue discounts
on fixed-income  securities  in  the  portfolio,  except  those  original  issue
discounts for which amortization is
 
                                       42
<PAGE>
   
required  for federal income tax purposes.  Additionally, with respect to market
discounts on bonds  issued after July  18, 1984, and  all bonds purchased  after
April  30, 1993, a portion of any  capital gain realized upon disposition may be
re-characterized as taxable ordinary income in accordance with the provisions of
the Internal Revenue Code.  Realized gains and  losses on security  transactions
are determined on the identified cost method. Dividend income is recorded on the
ex-dividend date. 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. In determining
amounts  to be  distributed, capital  gains will be  offset by  any capital loss
carryovers incurred in prior  years. The Fund incurred  and will elect to  defer
net capital losses of approximately $6,272,000 during fiscal year 1997.
    
 
    Any dividend or capital gains distribution received by a shareholder from an
investment  company will have the effect of  reducing the net asset value of the
shareholder's stock  in that  company by  the exact  amount of  the dividend  or
capital  gains distribution.  Furthermore, capital gains  distributions and some
portion of the dividends are subject to  federal income taxes. If the net  asset
value  of the shares should be reduced below a shareholder's cost as a result of
the payment of dividends or realized long-term capital gains, such payment would
be in  part a  return of  the shareholder's  investment to  the extent  of  such
reduction  below the shareholder's cost, but nonetheless would be taxable to the
shareholder. Therefore,  an investor  should consider  the tax  implications  of
purchasing Fund shares immediately prior to a distribution record date.
 
    Shareholders  should  consult  their  attorneys  or  tax  advisers regarding
specific questions as to state or local taxes and as to the applicability of the
foregoing to their current federal tax situation.
 
    SPECIAL RULES FOR CERTAIN FOREIGN CURRENCY TRANSACTIONS.  In general,  gains
from  foreign  currencies and  from foreign  currency options,  foreign currency
futures and forward foreign exchange contracts relating to investments in stock,
securities or  foreign  currencies are  currently  considered to  be  qualifying
income  for purposes  of determining whether  the Fund qualifies  as a regulated
investment company. It is currently unclear, however, who will be treated as the
issuer of certain foreign currency instruments or how foreign currency  options,
futures,  or forward foreign  currency contracts will be  valued for purposes of
the regulated investment company diversification requirements applicable to  the
Fund.  The Fund may  request a private  letter ruling from  the Internal Revenue
Service on some or all of these issues.
 
    Under Code Section 988, special rules are provided for certain  transactions
in  a  foreign currency  other than  the  taxpayer's functional  currency (I.E.,
unless certain special rules apply, currencies  other than the U.S. dollar).  In
general,  foreign currency gains or losses  from forward contracts, from futures
contracts that are not "regulated futures contracts", and from unlisted  options
will be treated as ordinary income or loss under Code Section 988. Also, certain
foreign  exchange gains or  losses derived with  respect to foreign fixed-income
securities are also  subject to  Section 988 treatment.  In general,  therefore,
Code  Section 988 gains  or losses will  increase or decrease  the amount of the
Fund's  investment  company  taxable  income  available  to  be  distributed  to
shareholders as ordinary income, rather than increasing or decreasing the amount
of  the Fund's net capital gain. Additionally, if Code Section 988 losses exceed
other investment company taxable  income during a taxable  year, the Fund  would
not be able to make any ordinary dividend distributions.
 
    If  the Fund invests in an entity  which is classified as a "passive foreign
investment company" ("PFIC") for U.S.  tax purposes, the application of  certain
technical  tax  provisions  applying  to  such  companies  could  result  in the
imposition of federal income  tax with respect to  such investments at the  Fund
level  which could not be eliminated  by distributions to shareholders. The U.S.
Treasury issued  proposed  regulation  section 1.1291-  8  which  establishes  a
mark-to-market  regime which allows investment  companies investing in PFIC's to
avoid most, if  not all, of  the difficulties posed  by the PFIC  rules. In  any
event,  it  is  not anticipated  that  any taxes  on  the Fund  with  respect to
investments in PFIC's would be significant.
 
    Shareholders are urged to consult their attorneys or tax advisers  regarding
specific questions as to federal, state or local taxes.

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 and/or
dividend 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
multipled by 2  to arrive  at the annualized  yield. For  the thirty-day  period
ended  March  31, 1997,  the Fund's  yield, calculated  pursuant to  the formula
described above, was 8.59%.
    
 
   
    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  fiscal year ended March  31, 1997 and for  the period June  2,
1994 through March 31, 1997 were 6.76% and 9.56%, 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 charge which,  if reflected, would  reduce
the  performance quoted.  For example, the  average annual total  returns of the
Fund may be calculated in the manner described above, but without deduction  for
any  applicable contingent deferred  sales charge. Based  upon this calculation,
the average annual total return of the Fund for the fiscal year ended March  31,
1997  and for  the period June  2, 1994 through  March 31, 1997  were 10.71% and
31.43%, 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  upon  the  foregoing
calculation, the aggregate total  return of the Fund  for the fiscal year  ended
March  31, 1997  and for  the period June  2, 1994  through March  31, 1997 were
10.71% and 10.14%, respectively.
    
 
   
    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
total aggregate total return to date (expressed as a decimal and without  taking
into  account the effect of applicable CDSC) and multiplying by $10,000, $50,000
or $100,000 as the case may be.  Investments of $10,000, $50,000 or $100,000  in
the  Fund at  the commencement  of its operations  would have  grown to $13,143,
$65,715 and $131,430, respectively, by March 31, 1997.
    
 
    The Fund from time  to time may also  advertise its performance relative  to
certain performance rankings and indexes compiled by independent organizations.

DESCRIPTION OF SHARES
- --------------------------------------------------------------------------------
 
   
    The shareholders of the Fund are entitled to a full vote for each full share
held.  All of the  Trustees have been  elected by the  shareholders of the Fund,
most recently at a Special Meeting of Shareholders held on May 21, 1997. On that
date, Wayne E. Hedien was also elected as a Trustee of the Fund with his term to
commence on September 1, 1997. 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 to  remove the  Trustees  following a  meeting called  for  that
purpose  requested in writing by the record holders of not less than ten percent
of the Fund's  outstanding shares.  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 presently have not  authorized
any such additional series or classes of shares.
    
 
    The  Declaration of  Trust 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 or her own bad
faith, willful misfeasance, gross  negligence, or reckless  disregard of his  or
her  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 liabilities 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.

DEAN WITTER HIGH INCOME SECURITIES
REPORT OF INDEPENDENT ACCOUNTANTS
 
TO THE SHAREHOLDERS AND TRUSTEES
OF DEAN WITTER HIGH INCOME SECURITIES
 
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 High Income Securities
(the "Fund") at March 31, 1997, the results of its operations for the year then
ended, the changes in its net assets for each of the two years in the period
then ended and the financial highlights for each of the two years in the period
then ended and for the period June 2, 1994 (commencement of operations) through
March 31, 1995, in conformity with generally accepted accounting principles.
These financial statements and financial highlights (hereafter referred to as
"financial statements") are the responsibility of the Fund's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these financial statements in accordance
with generally accepted auditing standards which require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits, which included confirmation of securities at March
31, 1997 by correspondence with the custodian and brokers, provide a reasonable
basis for the opinion expressed above.

DEAN WITTER HIGH INCOME SECURITIES
NOTES TO FINANCIAL STATEMENTS MARCH 31, 1997
 
1. ORGANIZATION AND ACCOUNTING POLICIES
 
Dean Witter High Income Securities (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 primary investment objective
is to earn a high level of current income and, as a secondary objective, capital
appreciation, but only when consistent with its primary objective. The Fund
seeks to achieve its objective by investing primarily in lower-rated fixed
income securities. The Fund was organized as a Massachusetts business trust on
March 23, 1994 and commenced operations on June 2, 1994.
 
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 -- (1) an equity security listed or traded on the
New York, American or other domestic or foreign stock exchange is valued at its
latest sale price on that exchange 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 a security is traded on more than one exchange, the security is
valued on the exchange designated as the primary market pursuant to procedures
adopted by the Trustees); (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; (3) when market
quotations are not readily available, including circumstances under which it is
determined by Dean Witter InterCapital Inc. (the "Investment Manager") that sale
and 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 Trustees
(valuation of debt securities for which market quotations are not readily
available may be based upon current market prices of securities which are
comparable in coupon, rating and maturity or an appropriate matrix utilizing
similar factors); (4) certain portfolio securities may be valued by an outside
pricing service approved by the 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, if available, in
determining what it believes is the fair valuation of the portfolio securities
valued by such pricing service; and (5) short-term debt securities having a
maturity date of more than sixty days at time of purchase are valued
 
                                       57
<PAGE>
DEAN WITTER HIGH INCOME SECURITIES
NOTES TO FINANCIAL STATEMENTS MARCH 31, 1997, CONTINUED
 
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.
Discounts are accreted over the life of the respective securities. Interest
income is accrued daily except where collection is not expected.
 
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 income to its shareholders.
Accordingly, no federal income tax provision is required.
 
D. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- The Fund records dividends and
distributions to its shareholders on the ex-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.
 
E. ORGANIZATIONAL EXPENSES -- The Investment Manager paid the organizational
expenses of the Fund in the amount of approximately $154,000 which haven been
reimbursed for the full amount thereof. Such expenses have been deferred and are
being amortized on the straight-line method over a period not to exceed five
years from the commencement of operations.
 
2. INVESTMENT MANAGEMENT AGREEMENT
 
Pursuant to an Investment Management Agreement, the Fund pays the Investment
Manager a management fee, calculated daily and payable monthly, by applying the
annual rate of 0.50% to the net assets of the Fund determined as of the close of
each business day. Effective May 1, 1996, the annual rate was reduced to 0.425%
for net assets in excess of $500 million.

<PAGE>
DEAN WITTER HIGH INCOME SECURITIES
NOTES TO FINANCIAL STATEMENTS MARCH 31, 1997, CONTINUED
 
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 0.80% 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 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, the
account executives of Dean Witter Reynolds Inc., an affiliate of the Investment
Manager and Distributor, and other employees or 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 incurred 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 Fund that such excess amounts,
including carrying charges, totaled $28,870,822 at March 31, 1997.
 
The Distributor has informed the Fund that for the year ended March 31, 1997, it
received approximately $1,408,000 in contingent deferred sales charges from
certain redemptions of the Fund's shares.
 
4. SECURITY TRANSACTIONS AND TRANSACTIONS WITH AFFILIATES
 
The cost of purchases and proceeds from sales of portfolio securities, excluding
short-term investments, for the year ended March 31, 1997 aggregated
$882,695,717 and $301,847,787, respectively.
 
Dean Witter Trust Company, an affiliate of the Investment Manager and the
Distributor, is the Fund's transfer agent. At March 31, 1997, the Fund had
transfer agent fees and expenses payable of approximately $66,000.

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


                                          2

<PAGE>

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

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

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

provided by law, by the Declaration or by these By-Laws, at all meetings of
Shareholders the holders of a majority of the Shares issued and outstanding
and entitled to vote thereat, present in person or represented by proxy,
shall be requisite and shall constitute a quorum for the transaction of
business. In the absence of a quorum, the Shareholders present or represented
by proxy and entitled to vote thereat shall have 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 Section 32 of the Corporations Law of the
State of Massachusetts.

   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 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

                                          3

<PAGE>

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

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

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

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

       (2) The determination shall be made:

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

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

       (iii) By the Shareholders.

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

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

        (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--


                                          4

<PAGE>

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

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

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

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

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

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

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

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

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

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

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

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

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

                                  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.


                                          5

<PAGE>

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

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

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

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

                                  ARTICLE VI

   SECTION 6.1. EXECUTIVE OFFICERS. The executive officers of the Trust shall

than one capacity. The executive officers of the Trust shall be elected
annually by the Trustees and each executive officer so elected shall hold
office until his 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

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 President to
the extent provided by the Trustees with respect to officers appointed by the
President.

between themselves and the Trust, shall have such authority and perform such
duties in the management of the Trust as may be provided in or pursuant to

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

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

                                 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.


                                          7

<PAGE>

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

                                 ARTICLE VIII
                            CERTIFICATES OF SHARES

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

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

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

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

                                  ARTICLE IX
                                  CUSTODIAN

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

     (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;


                                          8

<PAGE>

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

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

   SECTION 9.2. CENTRAL CERTIFICATE SYSTEM. Subject to such rules,
regulations and orders as the Commission may adopt, the Trustees may direct

Manager may reasonably require in order to discharge its duties and obligations

    4. The Investment Manager shall bear the cost of rendering the investment
management and supervisory services to be performed by it under this
Agreement, and shall, at its own expense, pay the compensation of the officers
and employees, if any, of the Fund, and provide such office space, facilities

<PAGE>
and such clerical help and bookkeeping services as the Fund shall reasonably

    5. The Fund assumes and shall pay or cause to be paid all other expenses of

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
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 the payment of any dividend, distribution, withdrawal or
redemption, whether in shares or in cash; charges and expenses of any outside
service used for pricing of the Fund's shares; charges and expenses of legal

independent accountants, in connection with any matter relating to the Fund;
membership dues of industry associations; interest payable on Fund borrowings;

Trustees) of the Fund which inure to its benefit; extraordinary expenses
(including but not limited to legal claims and liabilities and litigation costs
and any indemnification related thereto); and all other charges and costs of the
Fund's operation unless otherwise explicitly provided herein.
 
    6. For the services to be rendered, the facilties furnished, and the
expenses assumed by the Investment Manager, the Fund shall pay to the
Investment Manager monthly compensation determined by applying the following
annual rates to the Fund's daily net assets: 0.50% of daily net assets up to
$500 million; and 0.425% of daily net assets over $500 million. Except as
hereinafter set forth, compensation under this Agreement shall be calculated and
accrued daily and the amounts of the daily accruals shall be paid monthly. Such
calculations shall be made by applying 1/365ths of the annual rates to the
Fund's net assets each day determined as of the close of business on that day or
the last previous business day. If this Agreement becomes effective subsequent
to the first day of a month or shall terminate before the last day of a month,
compensation for that part of the month this Agreement is in effect shall be
prorated in a manner consistent with the calculation of the fees as set forth
above.
 
    Subject to the provisions of paragraph 7 hereof, payment of the Investment
Manager's compensation for the preceding month shall be made as promptly as
possible after completion of the computations contemplated by paragraph 7
hereof.
 
    7. In the event the operating expenses of the Fund, including amounts
payable to the Investment Manager pursuant to paragraph 6 hereof, for any
fiscal year ending on a date on which this Agreement is in effect, exceed the
expense limitations applicable to the Fund imposed by state securities laws or
regulations thereunder, as such limitations may be raised or lowered from time
to time, the Investment Manager shall reduce its management fee to the extent of
such excess and, if required, pursuant to any such laws or regulations, will
reimburse the Fund for annual operating expenses in excess of any expense
limitation that may be applicable; provided, however, there shall be excluded
from such expenses the amount of any interest, taxes, brokerage commissions,
distribution fees and extraordinary expenses (including but not limited to legal
claims and liabilities and litigations costs and any indemnification related
thereto) paid or payable by the Fund. Such reduction, if any, shall be computed
and accrued daily, shall be settled on a monthly basis, and shall be based upon
the expense limitation applicable to the Fund as at the end of the last
 
                                       2
<PAGE>
business day of the month. Should two or more such expense limitations be
applicable as at the end of the last business day of the month, that expense
limitation which results in the largest reduction in the Investment Manager's
fee shall be applicable.
 
    For purposes of this provision, should any applicable expense limitation be
based upon the gross income of the Fund, such gross income shall include, but
not be limited to, interest on debt securities in the Fund's portfolio accrued
to and including the last day of the Fund's fiscal year, and dividends declared
on equity securities in the Fund's portfolio, the record dates for which fall on
or prior to the last day of such fiscal year, but shall not include gains from
the sale of securities.
 
    8. The Investment Manager will use its best efforts in the supervision and
management of the investment activities of the Fund, but in the absence
of willful misfeasance, bad faith, gross negligence or reckless disregard of its
obligations hereunder, the Investment Manager shall not be liable to the Fund or
any of its investors for any error of judgment or mistake of law or for any act
or omission by the Investment Manager or for any losses sustained by the Fund or
its investors.
 
    9. Nothing contained in this Agreement shall prevent the Investment Manager
or any affiliated person of the Investment Manager from acting as
investment adviser or manager for any other person, firm or corporation and
shall not in any way bind or restrict the Investment Manager or any such
affiliated person from buying, selling or trading any securities or commodities
for their own accounts or for the account of others for whom they may be acting.
Nothing in this Agreement shall limit or restrict the right of any Director,
officer or employee of the Investment Manager to engage in any other business or
to devote his time and attention in part to the management or other aspects of
any other business whether of a similar or dissimilar nature.
 
   10. This Agreement shall remain in effect until April 30, 1999 and from year
to year thereafter provided such continuance is approved at least
annually by the vote of holders of a majority, as defined in the Investment
Company Act of 1940, as amended (the "Act"), of the outstanding voting
securities of the Fund or by the Trustees of the Fund; provided, that in either
event such continuance is also approved annually by the vote of a majority of
the Trustees of the Fund who are not parties to this Agreement or "interested
persons" (as defined in the Act) of any such party, which vote must be cast in
person at a meeting called for the purpose of voting on such approval; provided,
however, that (a) the Fund may, at any time and without the payment of any
penalty, terminate this Agreement upon thirty days' written notice to the
Investment Manager, either by majority vote of the Trustees of the Fund or by
the vote of a majority of the outstanding voting securities of the Fund; (b)
this Agreement shall immediately terminate in the event of its assignment (to
the extent required by the Act and the rules thereunder) unless such automatic
terminations shall be prevented by an exemptive order of the Securities and
Exchange Commission; and (c) the Investment Manager may terminate this Agreement
without payment of penalty on thirty days' written notice to the Fund. Any
notice under this Agreement shall be given in writing, addressed and delivered,
or mailed post-paid, to the other party at the principal office of such party.
 
   11. This Agreement may be amended by the parties without the vote or consent
of the shareholders of the Fund to supply any omission, to cure, correct
or supplement any ambiguous, defective or inconsistent provision hereof, or if
they deem it necessary to conform this Agreement to the requirements of
applicable federal laws or regulations, but neither the Fund nor the Investment
Manager shall be liable for failing to do so.
 
   12. This Agreement shall be construed in accordance with the laws of the
State of New York and the applicable provisions of the Act. To the extent
the applicable law of the State of New York, or any of the provisions herein,
conflict with the applicable provisions of the Act, the latter shall control.
 
   13. The Investment Manager and the Fund each agree that the name "Dean
Witter," which comprises a component of the Fund's name, is a property
right of Dean Witter Reynolds Inc. The Fund agrees and consents that (i) it will
only use the name "Dean Witter" as a component of its name and for no other
purpose, (ii) it will not purport to grant to any third party the right to use
the name "Dean Witter" for any purpose, (iii) the Investment Manager or its
parent, Morgan Stanley, Dean Witter, Discover & Co., or any
 
                                       3

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

                                DISTRIBUTION AGREEMENT

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

                                     WITNESSETH:

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

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

    NOW, THEREFORE, the parties agree as follows:

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

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

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

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

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

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

                                          1
<PAGE>

have been some other extraordinary event which, in the judgment of the Fund,
makes it impracticable to sell the Shares.

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

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

    SECTION 4.  REPURCHASE OR REDEMPTION OF SHARES.  (a)  Any of the
outstanding Shares may be tendered for redemption at any time, and the Fund
agrees to redeem the Shares so tendered in accordance with the applicable
provisions set forth in the Prospectus.  The price to be paid to redeem the
Shares shall be equal to the net asset value determined as set forth in the
Prospectus less any applicable contingent deferred sales charge.  All payments
by the Fund hereunder shall be made in the manner set forth below.

    The proceeds of any redemption of Shares shall be paid by the Trust as
follows: (i) any applicable contingent deferred sales charge shall be paid to
the Distributor or to the Selected Dealer, or, when applicable, pursuant to the
Rules of Fair Practice of the National Association of Securities Dealers, Inc.
("NASD"), retained by the Fund and (ii) the balance shall be paid to the
redeeming shareholders, in each case in accordance with applicable provisions of
the Prospectus, in New York Clearing House funds.  The Distributor is authorized
to direct the Trust to pay directly to any Selected Dealer any contingent
deferred sales charges payable by the Trust to the Distributor in respect of
Shares sold by the Selected Dealer to the redeeming shareholders.

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

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

    (d)  With respect to Shares tendered for redemption or repurchase by any
Selected Dealer on behalf of their customers, the Distributor is authorized to
instruct the transfer agent of the Trust to accept orders for redemption or
repurchase directly from the Selected Dealer on behalf of the Distributor and to
instruct the Trust to transmit payments for such redemption and repurchases
directly to the Selected Dealer on behalf of the Distributor for the account of
the shareholder.  The Distributor shall obtain from the Selected Dealer, and
shall maintain, a record of such orders.  The Distributor is further authorized
to obtain from the Trust, and shall maintain, a record of payments made directly
to the Selected Dealer on behalf of the Distributor.

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

    SECTION 5.  DUTIES OF THE FUND.  (a)  The Fund shall furnish to the
Distributor copies of all information, financial statements and other papers
which the Distributor may reasonably request for use in connection with the
distribution of the Shares, including one certified copy, upon request by the
Distributor, of all financial statements prepared by the Fund and examined by
independent accountants.  The Fund shall, at the expense of the Distributor,
make available to the Distributor such number of copies of the Prospectus as the
Distributor shall reasonably request.

    (b)  The Fund shall take, from time to time, but subject to the necessary
approval of its shareholders, all necessary action to fix the number of its
authorized Shares and to register Shares under the 1933 Act, to the end that
there will be available for sale such number of Shares as investors may
reasonably be expected to purchase.

    (c)  The Fund shall use its best efforts to pay the filing fees for an
appropriate number of the Shares for sale under the securities laws of such
states as the Distributor and the Fund may approve.  Any qualification to sell
its Shares in a state may be withheld, terminated or withdrawn by the Fund at
any time in its discretion.  As provided in Section 8(c) hereof, such filing
fees shall be borne by the Fund.  The Distributor shall furnish any information
and other material relating to its affairs and activities as may be required by
the Fund in connection with the sale of its Shares in any state.

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

    SECTION 6.  DUTIES OF THE DISTRIBUTOR.  (a)  The Distributor shall sell
Shares of the Trust through DWR and may sell Shares through other securities
dealers and shall devote reasonable time and effort to promote sales of the
Shares, but shall not be obligated to sell any specific number of Shares.  The
services of the Distributor hereunder are not exclusive and it is understood
that the Distributor may act as principal underwriter for other registered
investment companies so long as the performance of its obligations hereunder is
not impaired hereby.  It is also understood that Selected Dealers, including
DWR, may also sell shares for other registered investment companies.

    (b)  Neither the Distributor nor any Selected Dealer shall give any
information or make any representations, other than those contained in the
Registration Statement or related Prospectus and any sales literature
specifically approved by the Fund.

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

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

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

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

    SECTION 8.  PAYMENT OF EXPENSES.  (a)  The Distributor shall bear all
expenses incurred by it in connection with its duties and activities under this
Agreement including the payment to Selected Dealers


                                          3
<PAGE>

of any service fees and other expenses for sales of the Fund's Shares (except
such expenses as are specifically undertaken herein by the Fund) incurred or
paid by Selected Dealers, including DWR.  The Distributor shall bear the costs
and expenses of preparing, printing and distributing any supplementary sales
literature used by the Distributor or furnished by it for use by Selected
Dealers in connection with the offering of the Shares for sale.  Any expenses of
advertising incurred in connection with such offering will also be the
obligation of the Distributor.  It is understood and agreed that, so long as the
Fund's Plan of Distribution pursuant to Rule 12b-1 (the "Rule 12b-1 Plan")
under the 1940 Act continues in effect, any expenses incurred by the Distributor
hereunder may be paid in accordance with the terms of such Rule 12b-1 Plan.

    (b)  The Fund shall bear all costs and expenses of the Fund, including fees
and disbursements of legal counsel including counsel to the Trustees of the Fund
who are not interested persons (as defined in the 1940 Act) of the Fund or the
Distributor, and independent accountants, in connection with the preparation and
filing of any required Registration Statements and Prospectuses and all
amendments and supplements thereto, and the expense of preparing, printing,
mailing and otherwise distributing prospectuses and statements of additional
information, annual or interim reports or proxy materials to shareholders.

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

    SECTION 9.  INDEMNIFICATION.  (a)  The Fund shall indemnify and hold
harmless the Distributor and each person, if any, who controls the Distributor
against any loss, liability, claim, damage or expense (including the reasonable
cost of investigating or defending any alleged loss, liability, claim, damage or
expense and reasonable counsel fees incurred in connection therewith) arising by
reason of any person acquiring any Shares, which may be based upon the 1933 Act,
or on any other statute or at common law, on the ground that the Registration
Statement or related Prospectus and Statements of Additional Information, as
from time to time amended and supplemented, or the annual or interim reports to
shareholders of the Fund, includes an untrue statement of a material fact or
omits to state a material fact required to be stated therein or necessary in
order to make the statements therein not misleading, unless such statement or
omission was made in reliance upon, and in conformity with, information
furnished to the Fund in connection therewith by or on behalf of the
Distributor; provided, however, that in no case (i) is the indemnity of the Fund
in favor of the Distributor and any such controlling persons to be deemed to
protect the Distributor or any such controlling persons thereof against any
liability to the Fund or its security holders to which the Distributor or any
such controlling persons would otherwise be subject by reason of willful
misfeasance, bad faith or gross negligence in the performance of its duties or
by reason of reckless disregard of its obligations and duties under this
Agreement; or (ii) is the Fund to be liable under its indemnity agreement
contained in this paragraph with respect to any claim made against the
Distributor or any such controlling persons, unless the Distributor or any such
controlling persons, as the case may be, shall have notified the Fund in writing
within a reasonable time after the summons or other first legal process giving
information of the nature of the claim shall have been served upon the
Distributor or such controlling persons (or after the Distributor or such
controlling persons shall have received notice of such service on any designated
agent), but failure to notify the Fund of any such claim shall not relieve it
from any liability which it may have to the person against whom such action is
brought otherwise than on account of its indemnity agreement contained in this
paragraph.  The Fund will be entitled to participate at its own expense in the
defense, or, if it so elects, to assume the defense, of any suit brought to
enforce any such liability, but if the Fund elects to assume the defense, such
defense shall be conducted by counsel chosen by it and satisfactory to the
Distributor or such controlling person or persons, defendant or defendants in
the suit.  In the event the Fund elects to assume the defense of any such suit
and retain such counsel, the Distributor or such controlling person or persons,
defendant or defendants in the suit, shall bear the fees and expenses of any
additional counsel retained by them, but, in case the Fund does not elect to
assume the defense of any such suit, it will reimburse the Distributor


                                          4
<PAGE>

or such controlling person or persons, defendant or defendants in the suit, for
the reasonable fees and expenses of any counsel retained by them.  The Fund
shall promptly notify the Distributor of the commencement of any litigation or
proceedings against it or any of its officers or trustees in connection with the
issuance or sale of the Shares.

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

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

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

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

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

    This Agreement may be terminated at any time without the payment of any
penalty, by the Trustees of the Fund, by a majority of the Trustees of the Fund
who are not interested persons of the Fund and who have no direct or indirect
financial interest in this Agreement or by vote of majority of the outstanding
voting securities of the Fund, or by the Distributor, on sixty days' written
notice to the other party.  This Agreement shall automatically terminate in the
event of its assignment.


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

    SECTION 11.  AMENDMENTS OF THIS AGREEMENT.  This Agreement may be amended
by the parties only if such amendment is specifically approved by (i) the
Trustees of the Fund, or by the vote of a majority of outstanding voting
securities of the Fund, and (ii) a majority of those Trustees of the Fund who
are not parties to this Agreement or interested persons of any such party and
who have no direct or indirect financial interest in this Agreement or in any
Agreement related to the Fund's Plan of Distribution pursuant to Rule 12b-1
under the 1940 Act, cast in person at a meeting called for the purpose of voting
on such approval.

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

    SECTION 13.  PERSONAL LIABILITY.  The Declaration of the Trust establishing
Dean Witter High Income Securities, dated March 23, 1994, a copy of which,
together with all amendments thereto (the "Declaration"), is on file in the
office of the Secretary of the Commonwealth of Massachusetts, provides that the
name Dean Witter High Income Securities refers to the Trustees under the
Declaration collectively as Trustees, but not as individuals or personally; and
no Trustee, shareholder, officer, employee or agent of Dean Witter High Income
Securities shall be held to any personal liability, nor shall resort be had to
their private property for the satisfaction of any obligation or claim or
otherwise, in connection with the affairs of said Dean Witter High Income
Securities, but the Trust Estate only shall be liable.

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