               Dean Witter Convertible Securities Trust (the "Fund") is an
open-end diversified management investment company whose investment objective is
to seek a high level of total return on its assets through a combination of
current income and capital appreciation. It seeks to achieve its investment
objective by investing principally in "convertible securities," that is, bonds,
notes, debentures, preferred stocks and other securities which are convertible
into common stock. Investors should carefully consider the relative risks of
investing in a fund which may invest in securities assigned lower credit ratings
by national rating organizations and should be cognizant of the fact that such
securities are not generally meant for short-term investing (see "Investment
Objective and Policies").
               Shares of the Fund are continuously offered at net asset value
without the imposition of a sales charge. However, redemptions and/or
repurchases are subject in most cases to a contingent deferred sales charge,
scaled down from 5% to 1% of the amount redeemed, if made within six years of
purchase, which charge will be paid to the Fund's Distributor, Dean Witter
Distributors Inc. See "Redemptions and Repurchases--Contingent Deferred Sales
Charge." In addition, the Fund pays the Distributor a Rule 12b-1 distribution
fee pursuant to a Plan of Distribution at the annual rate of 1% 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."
               This Prospectus sets forth concisely the information you should
know before investing in the Fund. It should be read and retained for future
reference. Additional information about the Fund is contained in the Statement
of Additional Information, dated January 24, 1994, which has been filed with the
Securities and Exchange Commission, and which is available at no charge upon

1992, is a wholly-owned subsidiary of Dean Witter Reynolds Inc. ("DWR"). DWR  is
a  wholly-owned subsidiary of  Dean Witter, Discover &  Co. ("DWDC"), a balanced
financial services organization providing a  broad range of nationally  marketed
credit and investment products.

    InterCapital  and its wholly-owned subsidiary,  Dean Witter Services Company
Inc.,  serve  in  various   investment  management,  advisory,  management   and
administrative  capacities  to  a  total  of  seventy-nine  investment companies
twenty-seven of which are listed on  the New York Stock Exchange, with  combined
total  net assets of  approximately $69.2 billion  as of December  31, 1993. The
Investment Manager also manages  and advises managers  of portfolios of  pension
plans,  other institutions  and individuals which  aggregated approximately $2.0
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 Trustees review the  various services provided by the  Investment
Manager  to ensure that the Fund's  general investment policies and programs are
being properly carried out and  that administrative services are being  provided
to the Fund in a satisfactory manner.

    As  full compensation for the services  and facilities furnished to the Fund
and for expenses of the  Fund assumed by the  Investment Manager, the Fund  pays
the  Investment Manager  monthly compensation  calculated daily  by applying the
following annual rates to the  Fund's net assets determined  as of the close  of
each  business day: 0.60% of  the portion of the  daily net assets not exceeding
$750 million, scaled down at  various asset levels to  0.425% of the portion  of
the  daily net assets exceeding $3 billion.  For the fiscal year ended September
30, 1993,  the  Fund  accrued  total  compensation  to  the  Investment  Manager
amounting  to 0.60% of the Fund's average  daily net assets and the Fund's total
expenses amounted to 1.93% of the Fund's average daily net assets.

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

    The investment objective of the Fund is to seek a high level of total return
on its assets through a combination of current income and capital  appreciation.
There  is no assurance that this objective will be achieved. It is a fundamental
policy of  the Fund  and cannot  be changed  without shareholder  approval.  The
following  policies  may  be  changed  by  the  Trustees  of  the  Fund  without
shareholder approval.

    (1) The Fund will normally invest at least 65% of its total assets (taken at
current value) in "convertible securities," i.e., securities (bonds, debentures,
corporate notes, preferred  stocks and other  securities) which are  convertible
into  common stock. Securities  received upon conversion may  be retained in the
Fund's portfolio to permit orderly disposition or to establish long-term holding
periods for federal income tax purposes. The Fund is not required to sell  these
securities  for the purpose of  assuring that 65% of  its assets are invested in
convertible securities.

    (2) The Fund  may invest up  to 35% of  its total assets  (taken at  current
value and subject to any restrictions appearing elsewhere in this Prospectus) in
any  combination and quantity of the following securities: (a) common stock; (b)
nonconvertible preferred stock;  (c) nonconvertible  corporate debt  securities;
(d)  options on debt and equity  securities; (e) financial futures contracts and
related options thereon; and (f) money market instruments.

    (3) Notwithstanding paragraphs  (1) and  (2) above,  when market  conditions
dictate  a "defensive" investment strategy, the Fund may invest without limit in
money market instruments, including  commercial paper, 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 Fund may invest in fixed-income securities rated Baa or lower by Moody's
Investors  Service,  Inc. ("Moody's"),  or  BBB or  lower  by Standard  & Poor's
Corporation ("S&P"). Fixed-income securities rated Baa by Moody's or BBB by  S&P
have  speculative characteristics greater than those of more highly rated bonds,
while fixed-income securities rated Ba or BB

                                       5
<PAGE>
or lower by  Moody's and  S&P, 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 or C1  by S&P. 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. Bonds  rated C1 by  S&P, their lowest  bond rating, are  no
longer making interest payments.

    Non-rated securities are also 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.

    A  general description  of Moody's  and S&P's  ratings is  set forth  in the
Appendix at the end of this Prospectus.

PORTFOLIO CHARACTERISTICS

    CONVERTIBLE SECURITIES.  The Fund will seek to meet its investment objective
by investing primarily in convertible  securities in accordance with the  above-
stated  policies. Investments  in these securities  can provide a  high level of
total return by virtue  of their affording current  income through interest  and
dividend  payments  and  because of  the  opportunity they  provide  for capital
appreciation by virtue of their convertibility  into common stock. The Fund  may
invest  in investment  grade convertible securities  which are  rated within the
four highest categories by recognized rating agencies; i.e., S & P and  Moody's,
as  well as in such securities  which are lower rated or  which are not rated by
such agencies. See the Statement of  Additional Information for a discussion  of
S&P and Moody's ratings.

    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 investment  values and/or their  conversion
values in keeping with the Fund's objective.

    CORPORATE  FIXED-INCOME SECURITIES.  In order to generate the current income
needed to achieve its  investment objective, the Fund  may invest in  investment
grade nonconvertible fixed-income securities as well as in such securities which
are  in the lower rating categories of S &  P and Moody's or which are not rated
by such agencies. Such investments may be deemed speculative in nature.

    The ratings of fixed-income securities by Moody's and S & P are a  generally
accepted  barometer of credit  risk. The Investment  Manager will primarily rely
upon such  ratings in  assessing  the creditworthiness  of  the issuers  of  the
securities it purchases. Nevertheless, the Investment Manager takes into account
in  its security  selection process  the fact  that credit  ratings evaluate the
safety of a  security's continuing  payments of principal  and interest,  rather
than  the  risk of  decline  in its  market  value. Moreover,  as  credit rating
agencies may fail  to make  timely changes in  their credit  ratings to  reflect
changing  circumstances  and  events, the  Investment  Manger  will continuously
monitor the issuers of the lower-rated  securities held in the Fund's  portfolio
to    determine   whether    these   issuers    have   sufficient    cash   flow

                                       6
<PAGE>
and profits to meet required principal and interest payments.

    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.  The
interest  rate  risk  refers to  the  fluctuations  in net  asset  value  of any
portfolio of  fixed-income securities  resulting 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 fixed-income securities
decline, and when interest rates fall, prices rise.

    FOREIGN SECURITIES.  The Fund may invest in securities of foreign companies.
However, the  Fund will  not invest  more than  10% of  the value  of its  total
assets, at the time of purchase, in foreign securities (other than securities of
Canadian  issuers  registered  under  the Securities  Exchange  Act  of  1934 or
American Depository Receipts, on which there is no such limit).

    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. At the time the Fund makes
the commitment to purchase or sell securities on a when-issued, delayed delivery
or forward  commitment basis,  it  will record  the transaction  and  thereafter
reflect  the value,  each day,  of such  security purchased  or, if  a sale, the
proceeds to be  received, in determining  its net  asset value. At  the time  of
delivery of the securities, their value may be more or less than the purchase or
sale price.

    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 or debt restructuring. 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 5% 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  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 Adviser,  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.

SPECIAL INVESTMENT CONSIDERATIONS

    Because  of  the special  nature of  the Fund's  investments in  lower rated
securities (certain lower  rated securities  in which  the Fund  may invest  are
commonly  known  as junk  bonds), the  Investment Manager  must take  account of
certain special  considerations  in assessing  the  risks associated  with  such
investments.  For example,  as the lower  rated securities  market is relatively
new, its growth had paralleled a long economic expansion and, until recently, it
had not faced adverse economic and market conditions.

                                       7
<PAGE>
Therefore, an economic downturn or increase in interest rates is likely to  have
a  negative effect on this market and on the value of the lower rated securities
held by the Fund, as well as on the ability of the securities' issuers to  repay
principal and interest on their borrowings.

    The prices of lower rated securities have been found to be less sensitive to
changes  in prevailing  interest rates  than higher  rated investments,  but are
likely to be more sensitive to adverse economic changes or individual  corporate
developments.  During  an  economic  downturn or  substantial  period  of rising
interest rates, highly leveraged issuers  may experience financial stress  which
would  adversely effect  their ability to  service their  principal and interest
payment obligations,  to  meet  their  projected business  goals  or  to  obtain
additional financing. If the issuer of a fixed-income security owned by the Fund
defaults,  the Fund may incur additional expenses to seek recovery. In addition,
periods of  economic uncertainty  and change  can be  expected to  result in  an
increased   volatility  of  market  prices  of  lower  rated  securities  and  a
concomitant volatility in the net asset value of a share of the Fund.  Moreover,
the  market  prices of  certain  of the  Fund's  portfolio securities  which are
structured as  zero coupon  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 lower rated securities may be less liquid than  the
markets  for higher quality securities and, as  such, may have an adverse affect
on the market prices of certain securities. The limited liquidity of the  market
may also adversely affect the ability of the Fund's Trustees to arrive at a fair
value  for certain lower  rated securities at  certain times and  should make it
difficult for the Fund to sell certain securities.

    New laws and proposed new laws may have a potentially negative impact on the
market for  lower rated  securities. For  example, recent  legislation  requires
federally-insured  savings and loan associations  to divest their investments in
lower rated securities. This legislation and other proposed legislation may have
an adverse effect  upon the value  of lower rated  securities and a  concomitant
negative  impact upon  the net asset  value of a  share of the  Fund. During the
current fiscal  year,  the Fund's  investments  in lower-rated  securities  will
comprise less than 35% of the Fund's assets.

    During the fiscal year ended September 30, 1993, 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:

OPTIONS AND FUTURES TRANSACTIONS

    The Fund is permitted to  enter into call and  put options on U.S.  Treasury
notes,  bonds and bills and equity securities  which are listed on Exchanges and
are written in over-the-counter transactions ("OTC options"). Listed options are
issued by the Options  Clearing Corporation. 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, in an amount not exceeding 20% of the value of
its total assets, in order to aid it in achieving its investment objective.

    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 only
in order to close out a covered call position. The Fund may purchase put options
on securities 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. The Fund  may
also purchase put options to close out written put positions. There are no other
limits on the Fund's ability to purchase call and put options.

                                       8
<PAGE>
    The  Fund  may  purchase  and  sell  financial  futures  contracts ("futures
contracts") that  are traded  on  U.S. commodity  exchanges on  such  underlying
securities  as U.S.  Treasury bonds,  notes, and bills.  The Fund  may invest in
financial futures contracts only  as a hedge  against anticipated interest  rate
changes.

    The  Fund  may also  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. 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 and the sale of a futures
contract or to close out a long or short position in futures contracts.

    The  Fund may not  enter into futures contracts  or purchase related options
thereon if, immediately thereafter, the amount committed to initial 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%. Moreover, the Fund may only buy and write options which  are
listed  on national securities exchanges  and may not purchase  options if, as a
result, the aggregate cost of all outstanding options exceeds 10% of the  Fund's
total  assets. In addition, the Fund may  not purchase or sell futures contracts
or related options thereon  if, immediately thereafter,  more than one-third  of
its net assets would be hedged.
    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
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 generally will  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. Another 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. See the  Statement of Additional  Information for further
discussion of such 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
rating agencies,  research,  analysis and  appraisals  of brokers  and  dealers,
including  Dean Witter Reynolds  Inc. ("DWR"), a  broker-dealer affiliate of the
Investment Manager,  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
Small Capitalization Equities Group, which manages six funds and fund portfolios
with  approximately $2 billion in assets at October 31, 1993. Ronald J. Worobel,
Senior Vice  President of  InterCapital, and  a member  of InterCapital's  Small
    

                                       9
<PAGE>
Capitalization  Equities Group,  has been the  primary portfolio  manager of the
Fund since June, 1992 and has  been managing portfolios comprised of equity  and
other  securities at  InterCapital since June,  1992; prior  thereto Mr. Worobel
managed  portfolios  of  such  securities  at  MacKay  Shields  Financial  Corp.
(February, 1989-June, 1992) and Rothschild Inc. (June, 1986-February, 1989).

    Orders for transactions in portfolio securities are placed for the Fund with
a  number of  brokers and dealers,  including DWR.  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.

    The portfolio trading  engaged in by  the Fund may  result in its  portfolio
turnover  rate exceeding 100%. The Fund is  expected to incur higher than normal
brokerage commission costs due to its portfolio turnover rate. Short-term  gains
and  losses  taxable at  ordinary income  rates may  result from  such portfolio
transactions. See "Dividends, Distributions and Taxes" for a full discussion  of
the  tax implications of the Fund's  trading policy. A more extensive discussion
of the Fund's  portfolio brokerage  policies is set  forth in  the Statement  of
Additional Information.

    Except  as  specifically  noted,  all  investment  objectives,  policies and
practices discussed above are not fundamental policies of the Fund and, as such,
may be changed without shareholder approval.

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

    The investment restrictions  listed below  are among  the restrictions  that
have  been adopted  by the  Fund as  fundamental policies.  Under the Investment
Company Act of 1940,  as amended (the  "Act"), a fundamental  policy may not  be
changed  without the vote of a majority  of the outstanding voting securities of
the Fund, as defined in the Act.

    The Fund may not:

        1. Invest  more  than  5% of  the  value  of its  total  assets  in  the
    securities of any one issuer (other than obligations issued or guaranteed by
    the United States Government, its agencies or instrumentalities).

        2.  Purchase more than  10% of all outstanding  voting securities or any
    class of securities of any one issuer. For purposes of compliance with  this
    restriction,  the Fund will not invest  in the convertible securities of any
    one issuer if, upon conversion of such securities, the Fund would hold  more
    than 10% of the outstanding voting securities of that issuer.

        3.  Invest more than 25% of the  value of its total assets in securities
    of issuers  in  any  one  industry.  This  restriction  does  not  apply  to
    obligations  issued or  guaranteed by  the United  States Government  or its
    agencies or instrumentalities.

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

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

        6. Invest more than  5% of the  value of its  total assets in  warrants,
    including  not more than 2% of such  assets in warrants not listed on either
    the New  York  or  American  Stock Exchange.  However,  the  acquisition  of
    warrants attached to other securities is not subject to this restriction.

    If a percentage restriction is adhered to at the time of investment, a later
increase  or  decrease  in  percentage  resulting from  a  change  in  values of
portfolio securities or amount of total or  net assets will not be considered  a
violation of any of the foregoing restrictions.

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

    The  Fund offers its  shares for sale  to the public  on a continuous basis.
Pursuant  to  a  Distribution  Agreement  between  the  Fund  and  Dean   Witter
Distributors  Inc. (the "Distributor"), an  affiliate of the Investment Manager,
shares of the Fund  are distributed by  the Distributor and  offered by DWR  and
other  dealers  who  have  entered  into  selected  dealer  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. Subsequent purchases of $100 or more
may  be made by  sending a check  payable to Dean  Witter Convertible Securities
Trust 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. 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. In addition, the Fund will waive the minimum purchase
requirement for investments in connection  with certain Unit Investment  Trusts.
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").

    Shares of  the  Fund are  sold  through the  Distributor  on a  normal  five
business day settlement basis; that is, payment is due on the fifth 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  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 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"). The Fund  and the  Distributor reserve  the right  to reject  any
purchase orders.

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 1% 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 0.25% of the  Fund's
average  daily net assets, is characterized as  a service fee within the meaning
of NASD guidelines.

    Amounts paid under the Plan are paid to the Distributor to compensate it for
the services provided and  the expenses borne by  the Distributor and others  in
the  distribution of the Fund's shares, including the payment of commissions for
sales of the  Fund's shares and  incentive compensation to  and expenses of  DWR
account  executives and others who engage  in or support distributions 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

                                       11
<PAGE>
of a carrying charge on any unreimbursed distribution expenses.

    For  the fiscal  year ended  September 30,  1993, the  Fund accrued payments
under the Plan amounting  to $2,128,793, which  amount is equal  to 1.0% of  the
Fund's  average daily net assets for the fiscal year. The payments accrued under
the Plan were  calculated pursuant  to clause  (b) of  the compensation  formula
under the Plan.

    At any given time, the expenses of distributing shares of the Fund may be in
excess  of the total of (i) the payments  made by the Fund pursuant to the Plan,
and (ii) the  proceeds of contingent  deferred sales charges  paid by  investors
upon  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 such excess amounts including the carrying
charge described above, totalled  $63,406,891 at September  30, 1993, which  was
equal  to 30.4%  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,  this excess amount does not constitute  a liability of the Fund. Although
there is no legal obligation for the Fund to pay expenses incurred in excess  of
payments  made 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 on each  day that the  New York Stock  Exchange is open,  by
taking  the  value  of all  assets  of  the Fund,  subtracting  its liabilities,
dividing by the number of shares outstanding and adjusting to the nearest  cent.
The  net asset value per share will not be determined on Good Friday and on such
other federal and  non-federal holidays as  are observed by  the New York  Stock
Exchange.

    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 is  valued
at  its latest sale price on that exchange; 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 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, or when it
is determined  by  the  Investment Manager  that  sale  or bid  prices  are  not
reflective  of a security's fair value, portfolio securities are valued at their
fair value as determined in good faith under procedures established by and under
the general supervision of the Fund's Trustees.

    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' fair 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 utilizes  a
matrix  system  incorporating  security  quality,  maturity  and  coupon  as the
evaluation model parameters, and/or research evaluations by its staff, including
review of broker-dealer market price quotations in determining what it  believes
is  the  fair  valuation of  the  portfolio  securities valued  by  such pricing
service.

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  so acquired are not subject to the
imposition of  a contingent  deferred sales  charge upon  their redemption  (see
"Redemptions and Repurchases").

    EASYINVEST-TM-.    Shareholders may  subscribe  to EasyInvest,  an automatic
purchase plan  which  provides  for  any  amount  from  $100  to  $5,000  to  be
transferred automatically from a checking or savings account, on a semi-monthly,
monthly  or quarterly basis, to  the Transfer Agent for  investment in shares of
the Fund.

    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 through the
Distributor 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 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 Limited  Term
Municipal  Trust, Dean  Witter Short-Term Bond  Fund and five  Dean Witter Funds
which are money market funds (the foregoing eight 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 to another CDSC  fund or any Exchange Fund  that is not a money
market fund is on the basis of the next calculated net asset value per share  of
each  fund after the  exchange order is  received. When exchanging  into a money
market fund from the Fund,  shares of the Fund are  redeemed out of the Fund  at
their  next calculated net  asset value and  the proceeds of  the redemption are
used to  purchase shares  of the  money market  fund at  their net  asset  value
determined  the following business day. Subsequent  exchanges between any of the
money market funds and any of the CDSC funds can be effected on the same  basis.
No  contingent deferred  sales charge  ("CDSC") is  imposed at  the time  of any
exchange, although any applicable CDSC will be imposed upon ultimate redemption.
Shares of the Fund acquired in exchange for shares of another CDSC fund having a
different CDSC schedule  than that  of this  Fund will  be subject  to the  CDSC
schedule  of this  Fund, even if  such shares are  subsequently re-exchanged for
shares of the CDSC fund originally

                                       13
<PAGE>
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, if  any,
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 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.

    If  DWR or other 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 another  Selected  Broker-Dealer but  who wish  to make
exchanges directly by writing or  telephoning the Transfer Agent) must  complete
and  forward to  the Transfer  Agent an  Exchange Privilege  Authorization Form,
copies of  which  may  be obtained  from  the  Transfer Agent,  to  initiate  an
exchange. If the Authorization Form is used, exchanges may be made in writing or
by  contacting the Transfer Agent  at (800) 526-3143 (toll  free). The Fund will
employ reasonable procedures to confirm that exchange instructions  communicated
over  the telephone are  genuine. Such procedures  may include requiring various
forms of personal identification such as name, mailing address, Social  Security
or  other  tax identification  number and  DWR  or other  Selected Broker-Dealer
account number (if any).  Telephone instructions may also  be recorded. If  such
procedures  are  not employed,  the Fund  may be  liable for  any losses  due to
unauthorized or fraudulent instructions.

    Telephone exchange instructions will be accepted if received by the Transfer
Agent between 9:00 a.m.  and 4:00 p.m. New  York time, on any  day the New  York
Stock  Exchange is  open. Any  shareholder wishing to  make an  exchange who has
previously filed an Exchange Privilege Authorization  Form and who is unable  to
reach   the   Fund   by   telephone   should  contact   his   or   her   DWR  or

                                       14
<PAGE>
another Selected  Broker-Dealer account  executive, if  appropriate, or  make  a
written  exchange  request.  Shareholders  are advised  that  during  periods of
drastic economic or market changes, it  is possible that the telephone  exchange
procedures  may be difficult to  implement, although this has  not been the case
with the Dean Witter Funds in the past.

    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
will 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 sent to the Fund's  Transfer
Agent  at P.O. Box 983,  Jersey City, NJ 07303  is required. If certificates are
held by  the shareholder(s),  the shares  may be  redeemed by  surrendering  the
certificate(s)  with a written request for redemption, along with any additional
information required by the Transfer Agent.

    CONTINGENT DEFERRED SALES CHARGE.  Shares of the Fund which are held for six
years or more after purchase (calculated from the last day of the month in which
the shares were purchased)  will not be subject  to any charge upon  redemption.
Shares redeemed sooner than six years after purchase may, however, be subject to
a  charge upon  redemption. This charge  is called a  "contingent deferred sales
charge" ("CDSC"), which  will be  a percentage of  the dollar  amount of  shares
redeemed  and will be 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>
<CAPTION>
                                     CONTINGENT DEFERRED
            YEAR SINCE                   SALES CHARGE
             PURCHASE                 AS A PERCENTAGE OF
           PAYMENT MADE                AMOUNT REDEEMED
- -----------------------------------  --------------------
<S>                                  <C>
First..............................          5.0%
Second.............................          4.0%
Third..............................          3.0%
Fourth.............................          2.0%
Fifth..............................          2.0%
Sixth..............................          1.0%
Seventh and thereafter.............          None
</TABLE>

    A CDSC will not be imposed on:  (i) any amount which represents an  increase
in value of shares purchased within the six years preceding the redemption; (ii)
the current net asset value of shares purchased more than six years prior to the
redemption;  and (iii) the  current net asset value  of shares purchased through
reinvestment of dividends  or distributions and/or  shares acquired in  exchange
for  shares of Dean Witter Funds sold with  a front-end sales charge or of other
Dean Witter Funds acquired in exchange for such shares. Moreover, in determining
whether a CDSC is applicable it will  be assumed that amounts described in  (i),
(ii)  and (iii) above (in  that order) are redeemed  first. In addition, no CDSC
will be imposed on  redemptions of shares which  were purchased by certain  Unit
Investment  Trusts  (on  which  a  sales charge  has  been  paid)  or  which are
attributable to reinvestment of dividends or distributions from, or the proceeds
of, such Unit Investment Trusts.

    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 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

Sec-
                                       15
<PAGE>
tion 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 Internal Revenue 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.

    REPURCHASE.   DWR  and  other  Selected  Broker-Dealers  are  authorized  to
repurchase  shares represented by a share  certificate which is delivered to any
of their  offices.  Shares held  in  a  shareholder's account  without  a  share
certificate  may also  be repurchased by  DWR and  other Selected Broker-Dealers
upon the telephonic request of the shareholder. The repurchase price is the  net
asset  value next 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 upon repurchase by the Fund,
the Distributor, DWR  or other  Selected Broker-Dealers.  The offer  by DWR  and
other  Selected  Broker-Dealers to  repurchase shares  may be  suspended without
notice by them at any time. In that event, shareholders may redeem their  shares
through the Fund's Transfer Agent as set forth above under "Redemption."

    PAYMENT  FOR SHARES REDEEMED  OR REPURCHASED.   Payment for shares presented
for repurchase  or redemption  will be  made by  check within  seven days  after
receipt  by the Transfer Agent of the certificate and/or written request in good
order. Such payment may be postponed or the right of redemption suspended  under
unusual circumstances. 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 executives regarding restrictions on
redemption of shares of the Fund pledged in the margin account.

   
    REINSTATEMENT PRIVILEGE.   A  shareholder  who has  had  his or  her  shares
redeemed  or  repurchased and  has not  previously exercised  this reinstatement
privilege  may,  within  thirty  days  after  the  date  of  the  redemption  or
repurchase,  reinstate any portion or all of  the proceeds of such redemption or
repurchase in shares of the Fund at the net asset value next determined after  a
reinstatement  request, together with the proceeds,  is received by the Transfer
Agent and receive a pro-rata  credit for any CDSC  paid in connection with  such
redemption or repurchase.
    

    INVOLUNTARY REDEMPTION.  The Fund reserves the right, on sixty days' notice,
to  redeem, at their net asset value,  the shares of any shareholder (other than
shares held  in an  Individual  Retirement Account  or custodial  account  under
Section  403(b)(7) of the  Internal Revenue Code)  whose shares have  a value of
less than $100 or  such lesser amount  as may be fixed  by the Fund's  Trustees.
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 $100 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  $100 or  more
before  the redemption is processed. No CDSC  will be imposed on any involuntary
redemption.

<PAGE>
DIVIDENDS, DISTRIBUTIONS AND TAXES
- --------------------------------------------------------------------------------

    DIVIDENDS AND  DISTRIBUTIONS.   The  Fund intends  to pay  quarterly  income
dividends  and to distribute net short-term and  net long-term gains, if any, at
least once per year. The Fund may, however, determine either to distribute or to
retain all or part of any long-term gains in any year for reinvestment.

    All dividends and  capital gains  distributions will be  paid in  additional
Fund  shares  and automatically  credited to  the shareholder's  account without
issuance of a share certificate unless the shareholder requests in writing  that
all  dividends and/or distributions be paid  in cash. (See "Shareholder Services
- -- Automatic Investment of Dividends and Distributions".)

    TAXES.  Because the Fund intends to distribute substantially all of its  net
investment  income and  net capital gains  to shareholders  and otherwise remain
qualified as a regulated investment company  under Subchapter M of the  Internal
Revenue  Code, it  is not  expected that the  Fund will  be required  to pay any
federal income  tax on  such  income and  capital  gains. Shareholders  who  are
required  to pay taxes on their income  will normally have to pay federal income
taxes, and  any state  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 payments in additional shares or in cash.

    Gains or losses  on the  Fund's transactions in  listed non-equity  options,
futures  and options on futures  generally are treated as  60% long-term and 40%
short-term. When the Fund engages  in options and futures transactions,  various
tax  regulations applicable to the Fund may  have the effect of causing the Fund
to recognize  a gain  or loss  for  tax purposes  before that  gain or  loss  is
realized,  or  to  defer  recognition  of  a  realized  loss  for  tax purposes.
Recognition, for tax  purposes, of  an unrealized loss  may result  in a  lesser
amount of the Fund's realized gains being available for annual distribution.

    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 continue to comply with Subchapter M of the Code and remain
able  to forego payment of  Federal income tax on  its income and capital gains,
the Fund must  distribute all  of its  net investment  income, including  income
accrued  from zero coupon  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.

    One  of the  requirements for  the Fund to  remain qualified  as a regulated
investment company is that less than 30%  of the Fund's gross income be  derived
from  gains from the sale or other  disposition of securities held for less than
three months. Accordingly, the Fund may be restricted in the writing of  options
on  securities held for less than three  months, in the writing of options which
expire in less  than three months,  and in effecting  closing transactions  with
respect  to call or put  options which have been  written or purchased less than
three months prior to such transactions. The Fund may also be restricted in  its
ability to engage in transactions involving futures contracts.

    After  the  end  of  the  calendar  year,  shareholders  will  receive  full
information on their dividends and capital gains distributions for tax purposes.
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.

    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.

    Shareholders should consult their  tax advisers as  to the applicability  of
the foregoing to their current 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  year, five years and/or  the
life  of the Fund. Average annual total return reflects all income earned by the
Fund, any  appreciation  or depreciation  of  the Fund's  assets,  all  expenses
incurred  by the Fund  and all sales  charges incurred by  shareholders, for the
stated periods. It also assumes reinvestment of all dividends and  distributions
paid by the Fund.

    In  addition to the foregoing, the Fund  may advertise its total return over
different periods of time by means of aggregate, average, year-by-year or  other
types  of total  return figures.  Such calculations may  or may  not reflect the
deduction of the  contingent deferred  sales charge which,  if reflected,  would
reduce  the  performance  quoted. The  Fund  may  also advertise  the  growth of
hypothetical investments of $10,000, $50,000 and $100,000 in shares of the Fund.
The Fund  from time  to time  may  also advertise  its performance  relative  to
certain  performance rankings and indexes  compiled by independent organizations
(such as mutual fund performance rankings of Lipper Analytical Services, Inc.)

ADDITIONAL INFORMATION
- --------------------------------------------------------------------------------

    VOTING RIGHTS.  All shares of beneficial  interest of the Fund are of  $0.01
par value and are equal as to earnings, assets and voting privileges.

    The  Fund is  not required  to hold Annual  Meetings of  Shareholders and 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 the obligations of  the
Fund.  However,  the  Declaration of  Trust  contains an  express  disclaimer of
shareholder liability for acts  or obligations of the  Fund, requires that  Fund
obligations  include  such  disclaimer,  and  provides  for  indemnification and
reimbursement of expenses out  of the Fund's property  for any shareholder  held
personally  liable  for  the  obligations  of the  Fund.  Thus,  the  risk  of a
shareholder incurring  financial loss  on account  of shareholder  liability  is
limited  to circumstances in which  the Fund itself would  be unable to meet its
obligations. Given the above limitations  on shareholder personal liability  and
the  nature of the Fund's  assets and operations, the  possibility of the Fund's
being unable to  meet its obligations  is remote  and, thus, in  the opinion  of
Massachusetts  counsel to  the Fund, the  risk to Fund  shareholders of personal
liability is remote.

    SHAREHOLDER INQUIRIES.  All inquiries regarding the Fund should be  directed
to  the Fund at the telephone number 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.
</TABLE>

    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.

                                       19
<PAGE>
    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.
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.
</TABLE>

                                       20
<PAGE>

<TABLE>
<S>        <C>
B          Debt rated B has  a greater vulnerability  to default but presently  has the capacity  to
           meet  interest payments and principal repayments. Adverse business, financial or economic
           conditions would  likely  impair  capacity  or willingness  to  pay  interest  and  repay
           principal.
CCC        Debt rated CCC has a current identifiable vulnerability to default, and is dependent upon
           favorable business, financial and economic conditions to meet timely payments of interest
           and  repayments of  principal. In  the event of  adverse business,  financial or economic
           conditions, it is not likely to have the capacity to pay interest and repay principal.
CC         The rating CC is typically applied to debt subordinated to senior debt which is  assigned
           an actual or implied CCC rating.
C          The  rating C is typically applied to debt  subordinated to senior debt which is assigned
           an actual or implied CCC- debt rating.
CI         The rating CI is reserved for income bonds on which no interest is being paid.
NR         Indicates that no rating  has been requested, that  there is insufficient information  on
           which  to base  a rating or  that Standard &  Poor's does  not rate a  particular type of
           obligation as a matter of policy.
           Bonds rated  BB, B,  CCC,  CC and  C are  regarded  as having  predominantly  speculative
           characteristics  with  respect  to  capacity  to pay  interest  and  repay  principal. BB
           indicates the least degree of speculation and C the highest degree of speculation.  While
           such  debt  will  likely have  some  quality  and protective  characteristics,  these are
           outweighed by large uncertainties or major risk exposures to adverse conditions.
           Plus (+) or minus (-): The  ratings from AA to CCC may  be modified by the addition of  a
           plus or minus sign to show relative standing 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.
</TABLE>

                            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.

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

THE FUND

    The  Fund is a Trust of the type commonly known as a "Massachusetts business
trust" and was organized under the laws of the Commonwealth of Massachusetts  on
May 21, 1985.

THE INVESTMENT MANAGER

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

TCW/DW Term Trust 2002, TCW/DW Term Trust  2003 and TCW/DW Term Trust 2000  (the
"TCW/DW Funds"). InterCapital also serves as (i) sub-adviser to Templeton Global

Black Rock Strategic Term Trust Inc., a closed-end investment company; and (iii)
sub-administrator of Mass  Mutual Participation Investors  and Templeton  Global

    The  Investment Manager also serves as an investment adviser for Dean Witter
World Wide Investment Fund,  an investment company organized  under the laws  of
Luxembourg, shares of which may not be offered in the United States or purchased
by American citizens outside of the United States.

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

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

   
    On December  31,  1993,  InterCapital effected  an  internal  reorganization
pursuant to which administrative activities previously performed by InterCapital
are  instead performed by DWSC. Pursuant to the reorganization, InterCapital has
entered into a Services Agreement pursuant to which DWSC provides administrative
services to the Fund  that were previously  performed directly by  InterCapital.
The foregoing internal reorganization did not result in any change in the nature
or scope of the administrative services being provided to the Fund or any of the
fees  being paid by the Fund for  the overall services being performed under the
terms of the existing Management Agreement.
    

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

    As  full compensation for the services  and facilities furnished to the Fund
and expenses of the Fund  assumed by the Investment  Manager, the Fund pays  the
Investment  Manager  monthly  compensation  calculated  daily  by  applying  the
following annual rates to the Fund's daily  net assets: 0.60% of the portion  of
the  daily net assets  of the Fund not  exceeding $750 million  and 0.55% of the
portion of the  daily net  assets exceeding $750  million but  not exceeding  $1
billion;  0.50% of the portion of the daily  net assets of the Fund exceeding $1
billion but not  exceeding $1.5  billion; 0.475% of  the portion  of the  Fund's
daily  net assets exceeding $1.5 billion but  not exceeding $2 billion; 0.45% of
the portion  of  the  Fund's daily  net  assets  exceeding $2  billion  but  not
exceeding  $3 billion; and 0.425% of the  portion of the Fund's daily net assets
exceeding $3 billion. Total compensation  accrued to the Investment Manager  for
the fiscal years ended September 30, 1991, 1992 and 1993 amounted to $2,077,196,
$1,554,625 and $1,277,276, respectively.

    Total  operating expenses of the Fund  are subject to applicable limitations
under rules and regulations of states where  the Fund is authorized to sell  its
shares.  Therefore,  operating  expenses  are effectively  subject  to  the most
restrictive of such limitations as  the same may be  amended from time to  time.
Presently,  the most  restrictive limitation  is as  follows. If,  in any fiscal
year, the  Fund's  total  operating  expenses,  exclusive  of  taxes,  interest,
brokerage  fees,  distribution fees  and extraordinary  expenses (to  the extent
permitted by applicable state securities  laws and regulations), exceeds 2  1/2%
of the first $30,000,000 of average daily net assets, 2% of the next $70,000,000
of  average daily  net assets and  1 1/2%  of any excess  over $100,000,000, the
Investment Manager will reimburse the Fund  for the amount of such excess.  Such
amount,  if any, will be  calculated daily and credited  on a monthly basis. The
Fund did  not  exceed the  expense  limitation  during the  fiscal  years  ended
September 30, 1991, 1992 and 1993.

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

    The Agreement was initially approved by the Board of Trustees on October 30,
1992  and by the shareholders  of the Fund at  a Special Meeting of Shareholders
held on January 12,  1993. The Agreement is  substantially identical to a  prior
investment  management agreement which was initially approved by the Trustees on
July 19, 1985 and by DWR  as the sole shareholder on  August 8, 1985 and by  the
Shareholders  of the Fund at  a Special Meeting of  Shareholders on December 29,
1986. The Agreement took  effect on June  30, 1993 upon  the spin-off by  Sears,
Roebuck  & Co. of its  remaining shares of DWDC.  Under its terms, the Agreement
will continue in effect until April 30,  1994 and from year to year  thereafter,
provided  continuance of the Agreement is approved at least annually by the vote
of the holders of a majority, as  defined in the Act, of the outstanding  shares
of  the Fund, or by the 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 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, as
defined in the Investment  Company Act of 1940  (the "Act"), of the  outstanding
shares   of  the  Fund,  or  by  the  Investment  Manager.  The  Agreement  will
automatically terminate in the event of its assignment (as defined in the Act).

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

    The  Fund pays each Trustee who is not an employee of the Investment Manager
or an affiliated  company an  annual fee of  $1,600 ($1,200  after December  31,
1993)  plus $50 for each  meeting of the Board  of Trustees, the Audit Committee
and the Committee of the Independent Trustees attended by the Trustee in  person
(the  Fund pays the Chairman of the  Audit Committee an additional annual fee of
$1,200 ($1,000 after December 31, 1993)  and pays the Chairman of the  Committee
of  the Independent Trustees  an additional annual  fee of $2,400,  in each case
inclusive of the Committee meeting fees). The Fund also reimburses such Trustees
for travel and other out-of-pocket expenses incurred by them in connection  with
attending  such meetings. Trustees and officers of  the Fund who are employed by
the Investment  Manager or  an  affiliated company  receive no  compensation  or
expense reimbursement from the Fund.

    The Fund has adopted a retirement program under which an Independent Trustee
who  retires after  a minimum  required period of  service would  be entitled to
retirement payments upon reaching the  eligible retirement age (normally,  after
attaining  age 72) based upon length of  service and computed as a percentage of
one-fifth of the total  compensation earned by such  Trustee for service to  the
Fund  in the five-year period prior to  the date of the Trustee's retirement. No
Independent Trustee  has  retired since  the  adoption  of the  program  and  no
payments  by the Fund have  been made under the program  to any Trustee. For the
fiscal year ended September 30,  1993, the Fund accrued  a total of $37,058  for
Trustees'  fees,  expenses  and benefits  under  the  above-described retirement
program. As  of  the date  of  this  Statement of  Additional  Information,  the
aggregate 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
- --------------------------------------------------------------------------------

    CONVERTIBLE SECURITIES.    A convertible  security  entitles the  holder  to
exchange  it  for a  fixed  number of  shares of  common  stock or  other equity
security, usually of the same company, at fixed prices within a specified period
of time. As  such, a  convertible security entitles  the holder  to receive  the
fixed income of a bond or the dividend preference of a preferred stock until the
holder elects to exercise the conversion privilege.

    A  convertible security's position in  a company's capital structure depends
upon  its  particular  provisions.  In  the  case  of  subordinated  convertible
debentures,  the holders' claims on assets  and earnings are subordinated to the
claims of other creditors, and are senior to the claims of preferred and  common
shareholders. In the case of convertible preferred stock, the holders' claims on
assets  and earnings  are subordinated  to the claims  of all  creditors and are
senior to the claims of common shareholders.

    Every convertible security may be valued,  on a theoretical basis, as if  it
did not have a conversion privilege. Such theoretical value is determined by the
yield  it  provides  in  comparison  with  the  yields  of  other  securities of
comparable character and quality which do not have a conversion privilege.  This
theoretical  value, which will change with prevailing interest rates, the credit
standing of the issuer and other pertinent factors, is often referred to as  the
"investment  value,"  and represents  the  security's theoretical  price support
level.

    "Conversion value" is the  amount a convertible security  would be worth  in
market  value if  it were  to be  exchanged for  the underlying  equity security
pursuant to its conversion privilege. Conversion value fluctuates directly  with
the  price of the underlying equity  security, usually common stock. If, because
of low prices for the common stock, the conversion value is substantially  below
the  investment  value,  the  price  of  the  convertible  security  is governed
principally by  the  factors  described  in  the  preceding  paragraph.  If  the
conversion  value rises  near or  above its investment  value, the  price of the
convertible security  generally 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. If this appreciation potential is not realized,
this premium may not be recovered.

    To the  degree that  the price  of a  convertible security  rises above  its
investment  value  because  of  a rise  in  price  of the  common  stock,  it is
influenced more  by price  fluctuations of  the  common stock  and less  by  its
investment  value.  The  price  of  a  convertible  security  that  is supported
principally by its  conversion value will  rise along with  any increase in  the
price  of the common stock, and such price generally will decline along with any
decline in the price of the common  stock except that the security will  receive
additional  support  as its  price  approaches investment  value.  A convertible
security purchased  or held  at  a time  when its  price  is influenced  by  its
conversion   value  will  produce  a  lower  yield  than  nonconvertible  senior
securities with  comparable investment  values.  Convertible securities  may  be
purchased  by the  Fund at  varying price  levels above  their investment values
and/or their conversion values in keeping with the Fund's investment objectives.

    CORPORATE FIXED-INCOME SECURITIES.  As discussed in the Prospectus, in order
to generate the current income needed  to achieve its investment objective,  the
Fund  may invest in investment  grade non-convertible fixed-income securities as
well as  in  such  securities  which  are in  the  lower  rating  categories  of
recognized  rating agencies (Standard & Poor's Corporation and Moody's Investors
Service, Inc.) or which are not  rated by such agencies. The Investment  Manager
will  perform its  own credit  analyses in  addition to  using recognized rating
agencies  and  other  sources.  In  making  such  credit  analyses,  substantial
consideration  will be given to a determination of value based upon, among other
things, anticipated cash flows, interest  or dividend coverage, asset  coverage,
earnings,  experience of the issuer, responsiveness to changes in interest rates
and business conditions and liquidation value relative to the market price.

                                       9
<PAGE>
    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  high grade  debt 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 Investment Manager  and the Trustees do
not believe that the net asset value  of the Fund will be adversely affected  by
its purchase of securities on such basis. 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 sale. During the  fiscal year ended September 30, 1993, the
Fund did not purchase when, as and if issued securities.

OPTIONS AND FUTURES TRANSACTIONS

    The Fund  may write  covered call  options against  securities held  in  its
portfolio  and covered put options on eligible portfolio securities 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.

    Call  and put  options on  U.S. Treasury notes,  bonds and  bills and equity
securities  are  listed  on  Exchanges  (currently  the  Chicago  Board  Options
Exchange,  American  Stock  Exchange,  New York  Stock  Exchange,  Pacific Stock
Exchange and Philadelphia  Stock Exchange) and  are written in  over-the-counter
transactions  ("OTC Options"). Listed options are issued by the Options Clearing
Corporation ("OCC"). 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 interest 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.

                                       10
<PAGE>
    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.

    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,  without limit,  in  order  to aid  in  achieving its
investment objective. 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 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 deliverable under the call option. A
call option is also covered if the Fund holds a call on the same security as the
underlying security 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 high  grade debt  obligations  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 alone.  Moreover, the  premium
received will offset a portion of the potential loss incurred by the Fund if the
securities  underlying the option are ultimately sold by the Fund at a loss. The
premium received will fluctuate with varying economic market conditions. If  the
market  value  of the  portfolio securities  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 over-the-counter  ("OTC")  options,
during  the option period, the Fund may be required, at any time, to deliver the
underlying security against payment  of the exercise price  on any calls it  has
written  (exercise  of  certain  listed  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 from being  called,
to  permit the  sale of an  underlying security or  to enable the  Fund to write
another call option on the underlying security 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

                                       11
<PAGE>
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. 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.

    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  during
the  option period. If a  call option is exercised, the  Fund realizes a gain or
loss from the sale  of the underlying security  equal to the difference  between
the  purchase price of the  underlying security and the  proceeds of the sale of
the security plus the premium received 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 at the time the option
is written. See "Risks of Options Transactions," below.

    COVERED PUT WRITING.  As stated in the Prospectus, 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  put
options  written by  the Fund  will be  exercisable by  the purchaser  only on a
specific date).  A put  is "covered"  if  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 debt obligations  in an amount equal to at  least
the  exercise  price of  the  option, at  all  times during  the  option period.
Similarly, a written 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 high grade debt obligations 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). 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.

    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 call and  put
options  in  amounts equalling  up  to 10%  of its  total  assets. The  Fund may
purchase call options only in  order to close out  a covered call position  (see
"Covered  Call Writing" above). The  call purchased is likely  to be on the same
securities and  have the  same terms  as the  written option.  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 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. If the value of the underlying security 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

                                       12
<PAGE>
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 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 when it was purchased. Any such gain or
loss  could be offset in whole or in part by a change in the market value of the
underlying security. If a put option purchased by the Fund expired without being
sold or exercised, the Fund would realize a loss.

    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 increase, but has retained the risk of loss should the price
of the underlying security decline. The secured put writer also retains the risk
of loss should  the market value  of the underlying  security 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 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 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 an  underlying
security  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  would
continue  to bear  the risk  of decline  in the  market price  of the underlying
security until the option  expires or is exercised.  In addition, a covered  put
writer  would be unable to utilize the amount held in cash or U.S. Government or
other high grade  short-term debt obligations  as cover for  the put option  for
other investment purposes until the exercise or expiration of the option.

    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.  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). In addition, in the  event
of  the bankruptcy of a broker through which the Fund engages in transactions in
options, 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.

    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.

    In the event of the bankruptcy of a broker through which the Fund engages in
transactions  in  options, 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

                                       13
<PAGE>
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.

    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.

    FUTURES  CONTRACTS.  The  Fund may purchase and  sell futures contracts that
are traded on  U.S. commodity exchanges  on such underlying  securities as  U.S.
Treasury  bonds,  notes and  bills. 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.

    Although  most 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. A futures contract sale is closed out
by effecting a futures  contract purchase for the  same aggregate amount of  the
specific  type of 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 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.

    When  the Fund enters into  a 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  high grade  short-term  obligations  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 mark-to-market daily and the Fund
may be  required  to  make  subsequent  deposits  of  cash  or  U.S.  Government
securities  called "variation margin", with the Fund's futures contract clearing
broker, which  are reflective  of price  fluctuations in  the futures  contract.
Currently,  interest rate 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.

    OPTIONS  ON FUTURES CONTRACTS.  The Fund 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. An option  on a  futures contract gives  the purchaser  the right  (in

                                       14
<PAGE>
return for the premium paid), 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.  As stated
in the Prospectus, 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 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 Investment  Manager  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 order to assure  that the Fund is  entering into transactions in  futures
contracts  for hedging  purposes as such  is defined by  the Commodities Futures
Trading Commission either: 1) a  substantial majority (i.e., approximately  75%)
of  all anticipatory hedge transactions (transactions in which the Fund does not
own at  the time  of the  transaction, but  expects to  acquire, the  securities
underlying the relevant

                                       15
<PAGE>
futures  contract) involving the purchase of futures contracts will be completed
by the purchase  of securities  which are  the subject of  the hedge  or 2)  the
underlying  value of all long positions in futures contracts will not exceed the
total value of: a)  all short-term debt  obligations held by  the Fund; b)  cash
held  by the Fund; c) cash proceeds due to the Fund on investments within thirty
days;  d)  the  margin  deposited  on  the  contracts;  and  e)  any  unrealized
appreciation in the value of the contracts.

    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 high grade debt obligations 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, 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.

    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 high grade debt obligations  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.

    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  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  addition, in the  event of the
bankruptcy of a broker through which the Fund engages in transactions in 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.

    In the event of the bankruptcy of a broker through which the Fund engages in
transactions in 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.

    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  futures
contracts  may not move in tandem with  the changes in prevailing interest rates
against which the Fund 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.

    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

                                       16
<PAGE>
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.

    The  extent to which the Fund  may enter into transactions involving futures
contracts and options  thereon 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).

    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.

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 day's notice, or by
the Fund on  two business days'  notice. If  the borrower fails  to deliver  the
loaned  securities within two days after receipt  of notice, the Trust 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

                                       17
<PAGE>
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
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. However, the
Fund did not lend any of its  portfolio securities during the fiscal year  ended
September  30,  1993 and  it has  no intention  of doing  so in  the foreseeable
future.

REPURCHASE AGREEMENTS

    When cash may be available  for only a few days,  it may be invested by  the
Fund in repurchase agreements until such time as it may otherwise be invested or
used  for payments of  obligations of the  Fund. These agreements,  which may be
viewed as  a  type  of  secured  lending by  the  Fund,  typically  involve  the
acquisition  by the Fund of debt securities from a selling financial institution
such as a  bank, savings and  loan association or  broker-dealer. The  agreement
provides  that  the  Fund  will  sell back  to  the  institution,  and  that the
institution will repurchase,  the underlying security  ("collateral"), which  is
held  by the Fund's Custodian, at  a specified price and at  a fixed time in the
future, usually not more  than seven days  from the date  of purchase. The  Fund
will receive interest from the institution until the time when the repurchase is
to  occur. Although such date is deemed by the Fund to be the maturity date of a
repurchase  agreement,  the  maturities  of  securities  subject  to  repurchase
agreements  are  not  subject to  any  limits  and may  exceed  one  year. While
repurchase  agreements  involve  certain   risks  not  associated  with   direct
investments in debt securities, the Fund follows procedures designed to minimize
such risks. These procedures include effecting repurchase transactions only with
large,  well-capitalized  and  well-established  financial  institutions,  whose
financial condition  will be  continually monitored  by the  Investment  Manager
subject to procedures established by the Trustees. In addition, the value of the
collateral  underlying the repurchase agreement will always be at least equal to
the repurchase price, including  any accrued interest  earned on the  repurchase
agreement.  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  10%  of  its  total assets.  The  Fund's  investments  in repurchase
agreements may  at times  be substantial  when, in  the view  of the  Investment
Manager,  liquidity or other considerations warrant. The Fund did not enter into
any repurchase agreements during the fiscal year ended September 30, 1993, in an
amount greater than 5% of its net assets.

WARRANTS

    The Fund may invest  up to 5% of  its net assets in  warrants, but not  more
than 2% of such assets in warrants not listed on either the New York or American
Stock   Exchange.  However,  the  acquisition  of  warrants  attached  to  other
securities is  not  subject  to  this limitation.  For  the  fiscal  year  ended
September  30, 1993, the Fund's investments in warrants did not exceed 5% of its
net assets.

FOREIGN SECURITIES

    The Fund may invest  in securities of foreign  companies. However, the  Fund
will  not invest more than 10% of the value  of its total assets, at the time of
purchase, in foreign securities (other than securities of

                                       18
<PAGE>
Canadian issuers  registered  under  the  Securities Exchange  Act  of  1934  or
American  Depository Receipts, on which there  is no such limit). Investments in
certain Canadian issuers may be speculative  due to certain political risks  and
may be subject to substantial price fluctuations. 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.
Costs may be incurred in connection with conversions between various  currencies
held by the Fund.

    The  Fund may invest  in securities of foreign  companies. Dividends paid by
foreign issuers may be subject to withholding and other foreign taxes which  may
decrease the net return on such investments as compared to dividends paid to the
Fund  by  domestic corporations.  It  should be  noted  that there  may  be less
publicly  available  information  about  foreign  issuers  than  about  domestic
issuers, and foreign issuers are not subject to uniform accounting, auditing and
financial  reporting standards and requirements  comparable to those of domestic
issuers. Securities of some  foreign issuers are less  liquid and more  volatile
than securities of comparable domestic issuers and foreign brokerage commissions
are  generally higher than in the  United States. Foreign securities markets may
also be less liquid,  more volatile and less  subject to government  supervision
than  those in the United States. The Fund may be affected either unfavorably or
favorably by  fluctuations in  the relative  rates of  exchange as  between  the
currencies of different nations and exchange control regulations. Investments in
foreign  countries could be affected by other  factors not present in the United
States,   including   expropriation,   confiscatory   taxation   and   potential
difficulties  in  enforcing  contractual  obligations.  Securities  purchased on
foreign exchanges will  be held in  custody by  a foreign branch  of a  domestic
bank. During the fiscal year ended September 30, 1993, the Fund did not purchase
any foreign securities in an amount greater than 5% of its net assets.

PORTFOLIO TURNOVER

    The  Fund may sell portfolio securities without regard to the length of time
they have  been  held whenever  such  sale  will, in  the  Investment  Manager's
opinion,  strengthen  the  Fund's  position  and  contribute  to  its investment
objective. As a result,  the Fund's portfolio turnover  rate may exceed 100%.  A
100%  turnover rate would occur, for example,  if 100% 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
year ended September 30, 1993 the Fund's portfolio turnover rate was 221%.

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

         2. 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.

                                       19
<PAGE>
         3.  Purchase  or sell  commodities except  that  the Fund  may purchase
    financial futures contracts and related options thereon.

         4. 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.

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

         6.  Pledge its  assets or assign  or otherwise encumber  them except to
    secure  permitted  borrowings.  (For   the  purpose  of  this   restriction,
    collateral   arrangements  with  respect  to  the  writing  of  options  and
    collateral arrangements with  respect to  initial and  variation margin  for
    futures are not deemed to be pledges of assets and such arrangements are not
    deemed  to be the issuance of a  senior security as set forth in restriction
    (7).)

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

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

         9.  Make short sales of securities or maintain a short position, unless
    at all times when a short position is open it either owns an equal amount of
    such securities or  owns securities  which, without payment  of any  further
    consideration,  are convertible into  or exchangeable for  securities of the
    same issue as, and equal in amount to, the securities sold short.

        10. 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.

        11. 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.

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

    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
- --------------------------------------------------------------------------------

    The Investment  Manager  is  responsible  for  decisions  to  buy  and  sell
securities  and futures  contracts 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.  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.
Option  and futures transactions will usually be effected through a broker and a
commission will be charged.

                                       20
<PAGE>
    The Fund  also  expects  that  securities will  be  purchased  at  times  in
underwritten  offerings where the price includes a fixed amount of compensation,
generally referred to as the underwriter's concession or discount. On  occasion,
the  Fund may  also purchase certain  money market instruments  directly from an
issuer, in which case no commissions or discounts are paid.

    The Investment Manager currently serves as investment manager to a number of
clients, including other  investment companies,  and may  in the  future act  as
investment  manager or adviser to  others. It is the  practice of the Investment
Manager to cause purchase and sale  transactions to be allocated among the  Fund
and  others whose  assets it manages  in such  manner as it  deems equitable. In
making such  allocations among  the Fund  and other  client accounts,  the  main
factors  considered are the respective  investment objectives, the relative size
of portfolio holdings of the same or comparable securities, the availability  of
cash  for investment, the size of  investment commitments generally held and the
opinions of the persons responsible for managing the portfolios of the Fund  and
other client accounts.

    The  aggregate amount of  brokerage commissions paid by  the Fund during the
fiscal years ended September 30, 1991, 1992 and 1993 was $559,190, $288,676  and
$331,205, respectively.

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

    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.  During  the fiscal  year  ended  September 30,  1993,  the  Fund
directed  payment  of  $255,993  in  brokerage  commissions  in  connection with
transactions in  the aggregate  amount  of $148,640,816  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.

    Consistent with  the  policy  described  above,  brokerage  transactions  in
securities listed on exchanges or admitted to unlisted trading privileges may be
effected  through DWR. In order for DWR to effect portfolio transactions for the
Fund, the  commissions, fees  or  other remuneration  received  by DWR  must  be
reasonable and fair compared to the commissions, fees or other remuneration paid
to  other brokers in  connection with comparable  transactions involving similar
securities being purchased or sold on an exchange during a comparable period  of
time.  This standard would  allow DWR to  receive no more  than the remuneration
which would  be  expected  to  be  received  by  an  unaffiliated  broker  in  a
commensurate  arm's-length transaction.  Furthermore, the Trustees  of the Fund,
including a majority  of the Trustees  who are not  "interested" Trustees,  have
adopted   procedures  which  are   reasonably  designed  to   provide  that  any
commissions, fees or  other remuneration  paid to  DWR are  consistent with  the
foregoing  standard. During the fiscal years  ended September 30, 1991, 1992 and
1993, the Fund paid a total of

                                       21
<PAGE>
$152,394, $74,330 and  $20,207, respectively, in  brokerage commissions to  DWR.
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. During the fiscal
year ended September 30, 1993, the brokerage commissions paid to DWR represented
approximately 6.10% of the total brokerage  commissions paid by the Fund  during
the  year and were  paid on account  of transactions having  an aggregate dollar
value equal  to  approximately  6.86%  of the  aggregate  dollar  value  of  all
portfolio  transactions of the  Fund during the year  for which commissions were
paid.

    Section 11(a)  of  the  Securities  Exchange Act  of  1934  which  generally
prohibits  members of United States national securities exchanges from executing
exchange transactions for their affiliates and institutional accounts which they
manage, permits such exchange members to execute such securities transactions on
an exchange only if the affiliate  or account expressly consents. To the  extent
Section  11(a) would apply to DWR acting as a  broker for the Fund in any of its
portfolio transactions executed on any such securities exchange of which it is a
member, appropriate written consents have been given.

    During the  fiscal  year  ended  September  30,  1993,  the  Fund  purchased
securities  issued by The Bank  of New York and  Salomon, Inc., which issuers or
their  affiliates  were  among  the  ten  brokers  or  dealers  which   executed
transactions for or with the Fund in the largest dollar amounts during the year.
At  September 30, 1993, such  securities held by the Fund  had a market value of
$3,065,000 and $1,743,750, respectively.

THE DISTRIBUTOR
- --------------------------------------------------------------------------------

    As discussed in the Prospectus, shares  of the Fund are distributed by  Dean
Witter Distributors Inc. (the "Distributor"). The Distributor has entered into a
selected  dealer agreement with  DWR, which through  its own sales organization,
sells shares of the Fund. In  addition, the Distributor may enter into  selected
dealer  agreements  with  other  selected  broker-dealers.  The  Distributor,  a
Delaware corporation,  is  an  indirect wholly-owned  subsidiary  of  DWDC.  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)   at  their  meeting  held  on  October  30,  1992,  approved  the  current
Distribution Agreement appointing  the Distributor as  exclusive Distributor  of
the  Fund's  shares  and  providing for  the  Distributor  to  bear distribution
expenses  not  borne  by  The  Fund.  The  current  Distribution  Agreement   is
substantively  identical  to the  Fund's  previous distribution  agreements. The
Distribution Agreement took effect on June 30, 1993 upon the spin-off by  Sears,
Roebuck  and Co. of its remaining shares of DWDC. By its terms, the Distribution
Agreement will continue in effect  until April 30, 1994,  and from year to  year
thereafter if approved by the Board.

    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 to prospective shareholders. The Fund 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 of
omission or for any losses sustained by the Fund or its shareholders.

PLAN OF DISTRIBUTION

    To compensate the  Distributor for  the services provided  and the  expenses
borne  by  the  Distributor  or  any  selected  dealer  under  the  Distribution
Agreement, the Fund has adopted a Plan of Distribution

                                       22
<PAGE>
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  1.0% of the  lesser of:  (a) the average  daily aggregate  gross
sales  of  the Fund's  shares since  the  inception of  the Fund  (not including
reinvestment 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.  The  Distributor also
receives the proceeds of  contingent deferred sales  charges imposed on  certain
redemptions  of shares, which are separate and apart from payments made pursuant
to the  Plan. (see  "Redemptions and  Repurchases --  Contingent Deferred  Sales
Charge" in the Prospectus). The Distributor has informed the Fund that it and/or
DWR received approximately $975,000, $327,000 and $76,000 in contingent deferred
sales  charges for  the fiscal  years ended September  30, 1991,  1992 and 1993,
respectively, none of which was retained by the Distributor.

    The Distributor has informed the Fund that a portion of the fees payable  by
the  Fund each year  pursuant to the Plan  equal to 0.25%  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 portion of the fee is a payment made for personal
service and/or the maintenance of shareholder accounts. The remaining portion of
the Plan fees  payable by  the Fund is  characterized as  an "asset-based  sales
charge" as such is defined by the aforementioned Rules of Fair Practice.

    Under  its terms, the Plan had an initial term ending December 31, 1985, and
provides that it will  remain in effect from  year to year thereafter,  provided
such  continuance is approved  annually by a  vote of the  Trustees, including a
majority of  the Trustees  who are  not  "interested persons"  of the  Fund  (as
defined in the Act) and who have no direct or indirect financial interest in the
operation of the Plan (the "Independent 12b-1 Trustees"). The Plan was submitted
to  and approved by  the shareholders at  the Annual Meeting  of Shareholders on
December 29, 1986. Continuation  of the Plan was  most recently approved by  the
Trustees,  including a majority of the  Independent 12b-1 Trustees, on April 28,
1993 at a meeting called for the purpose of voting on such Plan. At that meeting
the Trustees  and  the Independent  12b-1  Trustees, after  evaluating  all  the
information  they deemed necessary to make  an informed determination of whether
the Plan should be continued, approved the continuation of the Plan until  April
30,  1994. The determination was based upon  the conclusion of the Trustees that
the Plan provides an effective means of stimulating sales of shares of the  Fund
and  of reducing or avoiding net redemptions and the potentially adverse effects
that may occur therefrom.

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

   
    Under the  Plan and  as required  by Rule  12b-1, the  Trustees receive  and
review promptly after the end of each calendar quarter a written report provided
by  the Distributor of the  amounts expended under the  Plan and the purpose for
which such  expenditures were  made. The  Fund accrued  amounts payable  to  the
Distributor  and DWR under the Plan, during  the fiscal year ended September 30,
1993, of  $2,128,793. This  amount is  equal  to payments  required to  be  paid
monthly  by the  Fund which  were computed  at the  annual rate  of 1.0%  of the
average daily net  assets of the  Fund for  the fiscal year  and was  calculated
pursuant  to clause (b) of the compensation  formula under the Plan. This amount
is treated by the Fund as an expense in the year it is accrued.
    

                                       23
<PAGE>
    The  Plan was adopted  in order to  permit the implementation  of the Fund's
method of distribution. Under this distribution  method, shares of the Fund  are
sold  without a sales load  being deducted at the time  of purchase, so that the
full amount of an investor's purchase payment will be invested in shares without
any deduction  for  sales charges.  Shares  of the  Fund  may be  subject  to  a
contingent deferred sales charge, payable to the Distributor, if redeemed during
the  six years after  their purchase. DWR compensates  its account executives by
paying them, from its own funds, commissions for the sale of the Fund's  shares,
currently  a gross sales  credit of up  to 5% of  the amount sold  and an annual
residual commission of  up to 0.25  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 DWR's  Fund associated  distribution-related expenses, including
overhead and  sales  compensation. The  distribution  fee that  the  Distributor
receives  from the Fund under the Plan, in effect, offsets distribution expenses
incurred under the Plan on behalf of the Fund and DWR's opportunity costs,  such
as  the gross  sales credit  and an  assumed interest  charge thereon ("carrying
charge"). In the  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 charge 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 $2,128,793  accrued under the Plan for the fiscal
year ended September 30,  1993 to the Distributor  and DWR. The Distributor  and
DWR  estimate that they have spent, pursuant to the Plan, $149,478,790 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)  1.15%  ($1,712,160) --
advertising  and  promotional  expenses;  (ii)  0.32%  ($478,893)  printing   of
prospectuses  for  distribution to  other than  current shareholders;  and (iii)
98.53% ($147,287,737) -- other  expenses, including the  gross sales credit  and
the  carrying charge, of which 21.84% ($32,172,520) represents carrying charges,
32.42% ($47,749,792) represents  commission credits  to DWR  branch offices  for
payments   of  commissions  to  account   executives  and  45.74%  ($67,365,425)
represents overhead and other  branch office distribution-related expenses.  The
term "overhead and other branch office distribution-related expenses" represents
(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.

    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 $63,406,891  as  of September  30,  1993.
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  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.

    No  interested person of the Fund nor any  Trustee of the Fund who is not an
interested person of the Fund, as defined  in the Act, has any direct  financial
interest in the operation of the Plan except to the

                                       24
<PAGE>
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.

    The  Plan may not be  amended to increase materially  the amount to be spent
for the services described therein without  approval by the shareholders of  the
Fund,  and all  material amendments  to the  Plan must  also be  approved by the
Trustees in the manner described above. The Plan may be terminated at any  time,
without  payment of any penalty, by vote  of a majority of the Independent 12b-1
Trustees or by a vote of a majority of the outstanding voting securities of  the
Fund (as defined in the Act) on not more than thirty days' written notice to any
other  party to the  Plan. So long  as the Plan  is in effect,  the election and
nomination of Independent 12b-1 Trustees shall be committed to the discretion of
the Independent 12b-1 Trustees.

DETERMINATION OF NET ASSET VALUE

    As stated in the Prospectus, short-term 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. Other short-term debt securities will be valued on a
mark-to-market basis until such time as they reach a remaining maturity of sixty
days,  whereupon they will be valued at  amortized cost using their value on the
61st day unless  the Trustees determine  such 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
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 and on
each other day in which  there is a sufficient degree  of trading in the  Fund's
investments  to affect the net asset value,  except that the net asset value may
not be computed on a day on which  no orders to purchase, or tenders to sell  or
redeem, Fund shares have been received, 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; President's Day; Good Friday;
Memorial Day; Independence Day; Labor Day; Thanksgiving Day; and Christmas Day.

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

    Upon the purchase of shares of the Fund, a Shareholder Investment Account is
opened for the investor on  the books of the Fund  and maintained by the  Fund's
Transfer  Agent, Dean  Witter Trust Company  (the "Transfer Agent").  This is an
open account in which shares owned by the investor are credited by the  Transfer
Agent  in lieu  of issuance of  a share  certificate. If a  share certificate is
desired, it must be requested in writing for each transaction. Certificates  are
issued  only for full shares and may be  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.

    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

                                       25
<PAGE>
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 change,  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  DWR  or  other  selected
broker-dealer, and will  be forwarded to  the shareholder, upon  the receipt  of
proper instructions.

    TARGETED  DIVIDENDS.-SM-    In  states  where  it  is  legally  permissible,
shareholders may also have all income dividends and capital gains  distributions
automatically invested in shares of an open-end Dean Witter Fund other than Dean
Witter  Convertible Securities Trust. Such investment  will be made as described
above for automatic investment in shares of the Fund, at the net asset value per
share of  the selected  Dean Witter  Fund as  of the  close of  business on  the
payment  date of the dividend or distribution  and will begin to earn dividends,
if any, in the selected Dean Witter  Fund the next business day. To  participate
in  the Targeted  Dividends program,  shareholders should  contact their  DWR or
other  selected  broker-dealer   account  executive  or   the  Transfer   Agent.
Shareholders  of the Fund must be shareholders  of the Dean Witter Fund targeted
to receive  investments from  dividends  at the  time  they enter  the  Targeted
Dividends  program. Investors should review the  prospectus of the targeted Dean
Witter Fund before entering the program.

    EASYINVEST.-SM-   Shareholders may  subscribe  to EasyInvest,  an  automatic
purchase  plan  which  provides  for  any  amount  from  $100  to  $5,000  to be
transferred automatically from a checking or savings account, on a semi-monthly,
monthly or quarterly basis,  to the Transfer Agent  for investment in shares  of
the Fund. Shares purchased through EasyInvest will be added to the shareholder's
existing  account at the  net asset value  calculated the same  business day the
transfer of  funds is  effected.  For further  information  or to  subscribe  to
EasyInvest,   shareholders   should  contact   their   DWR  or   other  selected
broker-dealer account executive or the Transfer Agent.

   
    INVESTMENT OF DIVIDENDS OR DISTRIBUTIONS RECEIVED IN CASH.  Any  shareholder
who  receives a cash payment representing  a dividend or distribution may invest
such dividend or distribution at the net asset value, without the imposition  of
a  contingent deferred sales  charge upon redemption, by  returning the check or
the proceeds to the Transfer Agent within thirty days after the payment date. If
the shareholder returns the proceeds of  a dividend or distribution, such  funds
must  be  accompanied  by  a  signed  statement  indicating  that  the  proceeds
constitute a dividend or  distribution to be invested.  Such investment will  be
made  at the  net asset  value per  share next  determined after  receipt of the
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").  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.

    The Transfer Agent  acts as agent  for the shareholder  in tendering to  the
Fund  for redemption sufficient full and fractional shares to provide the amount
of the periodic  withdrawal payment  designated in the  application. The  shares
will  be  redeemed at  their net  asset value  determined, at  the shareholder's
option, on the tenth or twenty-fifth day (or next following business day) of the
relevant month or quarter

                                       26
<PAGE>
and normally a check for the proceeds  will be mailed by the Transfer Agent,  or
amounts  credited  to  a  shareholder's  DWR  or  other  selected  broker-dealer
brokerage account, within five business days  after the date of redemption.  The
Withdrawal Plan may be terminated at any time by the Fund.

   
    Each  withdrawal constitutes  a redemption  of shares  and any  gain or loss
realized must  be  recognized for  federal  income tax  purposes.  Although  the
shareholder  may  make  additional  investments  of  $2,500  or  more  under the
Withdrawal Plan,  withdrawals made  concurrently  with purchases  of  additional
shares  may  be  inadvisable because  of  the contingent  deferred  sales charge
applicable to the redemption of shares purchased during the preceding six  years
(see "Redemption and Repurchases -- Contingent Deferred Sales Charge").
    

    Any  shareholder who wishes to have  payments under the Withdrawal Plan made
to a third party or sent to an address other than the one listed on the  account
must  send complete written instructions to the  Transfer Agent to enroll in the
Withdrawal Plan.  The  shareholder's  signature on  such  instructions  must  be
guaranteed   by  an  eligible   guarantor  acceptable  to   the  Transfer  Agent
(shareholders should  contact  the Transfer  Agent  for a  determination  as  to
whether  a particular institution is such  an eligible guarantor). A shareholder
may, at any time, change the amount and interval of withdrawal payments  through
his  or her account executive or by  written notification to the Transfer Agent.
In addition, the  party and/or the  address to  which checks are  mailed may  be
changed by written notification to the Transfer Agent, with signature guarantees
required  in the manner described above.  The shareholder may also terminate the
Withdrawal Plan at  any time by  written notice  to the Transfer  Agent. In  the
event  of  such  termination,  the  account  will  be  continued  as  a  regular
shareholder investment account. The shareholder may  also redeem all or part  of
the   shares  held  in  the  Withdrawal   Plan  account  (see  "Redemptions  and
Repurchases" in the Prospectus) at any time.

    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
Convertible Securities Trust 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 determined after receipt of the  check or purchase payment by the  Transfer
Agent. The shares so purchased will be credited to the investment 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  Limited Term Municipal  Trust, Dean  Witter Short-Term Bond
Fund and five  Dean Witter  Funds which are  money market  funds (the  foregoing
eight  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.

    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

                                       27
<PAGE>
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 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 charge 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.

    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 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 which  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

                                       28
<PAGE>
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.

    The Transfer Agent acts as agent  for shareholders of the Fund in  effecting
redemptions of Fund shares and in applying the proceeds to the purchase of other
fund  shares. In  the absence  of negligence on  its part,  neither the Transfer
Agent nor the Fund shall be liable  for any redemption of Fund shares caused  by
unauthorized  telephone instructions.  Accordingly, in  such event  the investor
shall bear the risk of loss. The staff of the Securities and Exchange Commission
is currently considering the propriety of such a policy.

   
    With respect to  the redemption  or repurchase of  shares of  the Fund,  the
application  of proceeds to the purchase of new  shares in the Fund or any other
of the  funds and  the general  administration of  the Exchange  Privilege,  the
Transfer  Agent  acts as  agent for  the Distributor  and for  the shareholder's
selected broker-dealer,  if  any, in  the  performance of  such  functions.  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 for  Dean
Witter  Short-Term U.S.  Treasury Trust is  $10,000, although that  fund, in its
discretion, may accept initial purchases as  low as $5,000. The minimum  initial
investment  for all other Dean Witter Funds  for which the Exchange Privilege is
available is $1,000.) Upon  exchange into an Exchange  Fund, the shares of  that
fund  will  be held  in  a special  Exchange  Privilege Account  separately from
accounts of those shareholders who have acquired their shares directly from that
fund. As a result, certain services normally available to shareholders of  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 this Exchange Privilege and provided further that the
Exchange  Privilege may  be terminated or  materially revised  without notice at
times (a) when the New  York Stock Exchange is  closed for other than  customary
weekends and holidays, (b) when trading on that Exchange is 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.

    The current prospectus for each  fund describes its investment  objective(s)
and  policies, and  shareholders should obtain  a copy and  examine it carefully
before investing. An exchange  will be treated for  federal income tax  purposes
the   same   as  a   repurchase   or  redemption   of   shares,  on   which  the

                                       29
<PAGE>
shareholder may realize a capital gain  or loss. However, the ability to  deduct
capital  losses on an  exchange may be  limited in situations  where there is an
exchange of  shares within  ninety  days after  the  shares are  purchased.  The
Exchange  Privilege is only available in states where an exchange may legally be
made.

    For further  information  regarding  the  Exchange  Privilege,  shareholders
should  contact their DWR  or other selected  broker-dealer account executive or
the Transfer Agent.

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 certificate, must  be sent to the  Fund's Transfer Agent, which will
redeem the shares at their net asset value next computed (see "Purchase of  Fund
Shares"  in the Prospectus)  after it receives the  request, and certificate, if
any, in good order. Any redemption request received after such computation  will
be  redeemed at the next determined net asset value. The term "good order" means
that the share  certificate, if  any, and  request for  redemption are  properly
signed,  accompanied by  any documentation required  by the  Transfer Agent, and
bear signature guarantees when  required by the Fund  or the Transfer Agent.  If
redemption  is requested by a corporation,  partnership, trust or fiduciary, the
Transfer Agent may require that written evidence of authority acceptable to  the
Transfer Agent be submitted before such request is accepted.

    Whether  certificates are held  by the shareholder  or shares are  held in a
shareholder's account, if the proceeds are to  be paid to any person other  than
the record owner, or if the proceeds are to be paid to a corporation (other than
the Distributor or a selected broker-dealer for the account of the shareholder),
partnership,  trust or fiduciary, or sent to the shareholder at an address other
than the  registered  address, signatures  must  be guaranteed  by  an  eligible
guarantor  acceptable  to the  Transfer Agent  (shareholders should  contact the
Transfer Agent for  a determination as  to whether a  particular institution  is
such  an eligible guarantor). A  stock power may be  obtained from any dealer or
commercial bank. The Fund may  change the signature guarantee requirements  from
time  to  time upon  notice to  shareholders, which  may  be by  means of  a 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 six years. However, no CDSC will be
imposed  to the extent that the net asset  value of the shares redeemed does not
exceed: (a) the current net asset value of shares purchased more than six  years
prior  to  the  redemption, plus  (b)  the  current net  asset  value  of shares
purchased through  reinvestment of  dividends or  distributions of  the Fund  or
another  Dean Witter  Fund (see  "Shareholder Services  -- Targeted Dividends"),
plus (c) the  current net asset  value of  shares acquired in  exchange for  (i)
shares of Dean Witter front-end sales charge funds, or (ii) shares of other Dean
Witter  Funds  for  which  shares  of front-end  sales  charge  funds  have been
exchanged (see "Shareholder Services -- Exchange Privilege"), plus (d) increases
in the  net asset  value of  the investor's  shares above  the total  amount  of
payments  for the purchase of  Fund shares made during  the preceding six years.
The CDSC will be paid to the  Distributor. In addition, no CDSC will be  imposed
on  redemptions of shares which were purchased by certain Unit Investment Trusts
(on  which  a  sales  charge  has  been  paid)  or  which  are  attributable  to
reinvestment  of dividends or distributions from,  or the proceeds of, such Unit
Investment Trusts.

                                       30
<PAGE>
    In determining the applicability of the CDSC to each redemption, the  amount
which  represents an increase  in the net  asset value of  the investor's shares
above the amount of  the total payments  for the purchase  of shares within  the
last  six  years will  be redeemed  first.  In the  event the  redemption amount
exceeds such increase in value, the next portion of the amount redeemed will  be
the  amount  which  represents the  net  asset  value of  the  investor's shares
purchased more than six  years prior to the  redemption and/or shares  purchased
through  reinvestment of  dividends or  distributions and/or  shares acquired in
exchange for shares of Dean Witter  front-end sales charge funds, or for  shares
of other Dean Witter funds for which shares of front-end sales charge funds have
been  exchanged. A portion of the amount  redeemed which exceeds an amount which
represents both such increase  in value and the  value of shares purchased  more
than  six  years  prior  to  the  redemption  and/or  shares  purchased  through
reinvestment of  dividends  or  distributions  and/or  shares  acquired  in  the
above-described exchanges will be subject to a CDSC.
    The  amount of the CDSC, if any, will  vary depending on the number of years
from the time  of payment  for the  purchase of Fund  shares until  the time  of
redemption  of such shares. For purposes of determining the number of years from
the time of any payment for the  purchase of shares, all payments made during  a
month  will be aggregated  and deemed to have  been made on the  last day of the
month. The following table sets forth the rates of the CDSC:

</TABLE>

    In determining the rate of the CDSC it will be assumed that a redemption  is
made  of shares held by  the investor for the longest  period of time within the
applicable six-year period. This will result  in any such CDSC being imposed  at
the   lowest  possible  rate.  Accordingly,  shareholders  may  redeem,  without
incurring any CDSC,  amounts equal to  any net  increase in the  value of  their
shares  above the  amount of  their purchase payments  made within  the past six
years and amounts equal to the current  value of shares purchased more than  six
years  prior  to the  redemption and  shares  purchased through  reinvestment of
dividends or distributions  or acquired in  exchange for shares  of Dean  Witter
front-end sales charge funds, or for shares of other Dean Witter Funds for which
shares  of front-end sales  charge funds have  been exchanged. The  CDSC will be
imposed, in accordance with the table shown above, on any redemptions within six
years of purchase which are in excess of these amounts and which redemptions are
not (a)  requested  within  one  year  of  death  or  initial  determination  of
disability   of  a  shareholder,  or  (b)   made  pursuant  to  certain  taxable
distributions from retirement plans or retirement accounts, as described in  the
Prospectus.

    PAYMENT FOR SHARES REDEEMED OR REPURCHASED.  As discussed in the Prospectus,
payment  for shares presented for repurchase or redemption will be made by check
within seven days after receipt by the Transfer Agent of the certificate  and/or
written  request  in  good order.  The  term  good order  means  that  the share
certificate, if any, and request for redemption are properly signed, accompanied
by any  documentation  required  by  the  Transfer  Agent,  and  bear  signature
guarantees  when required by the Fund or the Transfer Agent. Such payment may be
postponed or the right of  redemption suspended at times  (a) when the New  York
Stock  Exchange is  closed for other  than customary weekends  and holidays, (b)
when trading on that Exchange is restricted,  (c) when an emergency exists as  a
result of which disposal by the Fund of securities owned by it is not reasonably
practicable or it is not reasonably practicable for the Fund fairly to determine
the  value of its net assets, or (d) during any other period when the Securities
and Exchange Commission by order so permits; provided that applicable rules  and

                                       31
<PAGE>
regulations of the Securities and Exchange Commission shall govern as to whether
the conditions prescribed in (b) or (c) exist. If the shares to be redeemed have
recently  been purchased  by check  (including a  certificate or  bank cashier's
check), payment  of redemption  proceeds may  be delayed  for the  minimum  time
needed  to verify that the check used  for investment has been honored (not more
than fifteen days  from the  time of  investment of  the 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
shares to a  new registration,  such shares  will be  transferred without  sales
charge  at the time of  transfer. With regard to the  status of shares which are
either subject to the  contingent deferred sales charge  or free of such  charge
(and  with regard to the  length of time shares subject  to the charge have been
held), any transfer involving less than all of the shares in an account will  be
made on a pro-rata basis (that is, by transferring shares in the same proportion
that  the transferred shares bear to the total shares in the account immediately
prior to the transfer).  The transferred shares will  continue to be subject  to
any  applicable contingent  deferred sales  charge as  if they  had not  been so
transferred.

    REINSTATEMENT PRIVILEGE.  As discussed in the Prospectus, a shareholder  who
has  had  his or  her  shares redeemed  or  repurchased and  has  not previously
exercised this reinstatement privilege may within thirty days after the date  of
redemption  or repurchase reinstate any  portion or all of  the proceeds of such
redemption or repurchase  in shares  of the  Fund at  the net  asset value  next
determined  after  the reinstatement  request, together  with such  proceeds, is
received by the Transfer Agent.

    Exercise of the reinstatement privilege  will not affect the federal  income
tax treatment of any gain or loss realized upon redemption or repurchase, except
that  if the redemption  or repurchase resulted  in a loss  and reinstatement is
made in shares of  the Fund, some or  all of the loss,  depending on the  amount
reinstated,  will not be allowed as a  deduction for federal income tax purposes
but will  be applied  to  adjust the  cost basis  of  the shares  acquired  upon
reinstatement.

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

    As 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.

    Because the Fund intends to distribute all of its net investment income  and
capital  gains to shareholders and otherwise  continue to qualify as a regulated
investment company under Subchapter  M of the Internal  Revenue Code, it is  not
expected  that  the  Fund  will  be required  to  pay  any  federal  income tax.
Shareholders will  normally have  to pay  federal income  taxes, and  any  state
income  taxes, on  the dividends and  distributions they receive  from the Fund.
Such dividends and distributions, to the  extent that they are derived from  net
investment income or short-term capital gains, are taxable to the shareholder as
ordinary  income regardless of whether the shareholder receives such payments in
additional shares or in cash. Any dividends declared in the last quarter of  any
year  which are paid  in the following year  prior to February  1 will be deemed
received by the shareholder in the prior year.

    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.

    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.

                                       32
<PAGE>
    At  September  30,  1993,  the  Fund  had  net  capital  loss  carryovers of
approximately $402,612,000  of  which  $39,332,000  will  be  available  through
September  30, 1996, $218,065,000 will be  available through September 30, 1997,
$36,349,000 will be available  through September 30,  1998, $46,135,000 will  be
available  through September 30, 1999 and  $62,731,000 will be available through
September 30, 2000  to offset future  capital gains, to  the extent provided  by
regulations. To the extent that these capital loss carryovers are used to offset
future  capital  gains, it  is probable  that the  gains so  offset will  not be
distributed to  shareholders since  any  such distributions  may be  taxable  to
shareholders as ordinary income.

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

    Any dividend or capital  gains distribution received  by a shareholder  from
any  investment company will have the effect  of reducing the net asset value of
the shareholder's stock in that company by  the exact amount of the dividend  or
capital   gains  distribution.  Furthermore,  capital  gains  distributions  and
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 the  distribution  of realized  long-term capital  gains,  such
payment  or  distribution  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  fully taxable at  either ordinary or  capital gain rates.
Therefore, an investor should consider  the tax implications of purchasing  Fund
shares immediately prior to a dividend or distribution record date.

    Dividend  payments  will  be  eligible for  the  federal  dividends received
deduction available to the Fund's corporate shareholders only to the extent  the
aggregate  dividends received by the Fund would be eligible for the deduction if
the Fund were  the shareholder  claiming the dividends  received deduction.  The
amount  of  dividends paid  by  the Fund  which  may qualify  for  the dividends
received deduction is limited  to the aggregate  amount of qualifying  dividends
which the Fund derives from its portfolio investments which the Fund has held to
a  minimum period, usually 46 days. Any  distributions made by the Fund will not
be eligible for the  dividends received deduction with  respect to shares  which
are  held by  the shareholder for  45 days  or less. Any  long-term capital gain
distributions will also not  be eligible for  the dividends received  deduction.
The ability to take the dividends received deduction will also be limited in the
case  of  a Fund  shareholder which  incurs or  continues indebtedness  which is
directly attributable to its investment in the Fund.

    After the end  of the year,  shareholders will be  sent full information  on
their  dividends  and capital  gains distributions  for tax  purposes, including
information as to the portion taxable as ordinary income, the portion taxable as
long-term capital  gains and  the portion  eligible for  the dividends  received
deduction.  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  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

                                       33
<PAGE>
entitled to dividends. This amount is added to 1 and raised to the sixth  power.
1  is then subtracted from  the result and the difference  is multiplied by 2 to
arrive at the annualized yield. For the 30-day period ended September 30,  1993,
the Fund's yield, calculated pursuant to the formula described above, was 1.89%.

    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 return  of
the  Fund for the fiscal year ended September 30, 1993, for the five years ended
September 30, 1993  and for the  period from October  31, 1985 (commencement  of
operations)   through  September   30,  1993   was  18.22%,   8.83%  and  7.50%,
respectively.

    In addition to the foregoing, the  Fund may advertise its total return  over
different  periods of time by means of aggregate, average, year-by-year or other
types of total  return figures.  Such calculations may  or may  not reflect  the
deduction  of the  contingent deferred sales  charge which,  if reflected, would
reduce the performance quoted. For example,  the average annual total return  of
the  Fund may be calculated in the manner described above, but without deduction
for any applicable contingent deferred sales charge. Based on this  calculation,
the  average annual total return of the Fund for the fiscal year ended September
30, 1993, for the five  years ended September 30, 1993  and for the period  from
October  31,  1985  through September  30,  1993  was 23.22%,  7.50%  and 9.11%,
respectively.

    In addition, the Fund may compute  its aggregate total return for  specified
periods  by determining the  aggregate percentage rate which  will result in the
ending value of a  hypothetical $1,000 investment made  at the beginning of  the
period.  For the purpose of  this calculation, it is  assumed that all dividends
and distributions  are reinvested.  The formula  for computing  aggregate  total
return  involves a percentage obtained by dividing the ending value (without the
reduction for  any  contingent deferred  sales  charge) by  the  initial  $1,000
investment   and  subtracting  1  from  the   result.  Based  on  the  foregoing
calculation, the Fund's  total return for  the fiscal year  ended September  30,
1993,  for  the five  years ended  September 30,  1993 and  for the  period from
October 31,  1985 through  September 30,  1993 was  23.22%, 54.65%  and  77.31%,
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
aggregate  total return to date (expressed as  a decimal and without taking into
account the  extent of  any  applicable contingent  deferred sales  charge)  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 inception  would have  grown  to
$17,731, $88,655 and $177,310, respectively, at September 30, 1993.

    The  Fund  may advertise,  from time  to time,  its performance  relative to
certain performance rankings and indexes compiled by independent organizations.

DESCRIPTION OF SHARES OF THE FUND
- --------------------------------------------------------------------------------

    As discussed in the Prospectus, the shareholders of the Fund are entitled to
a full vote  for each full  share held. The  Trustees have been  elected by  the
shareholders  of the  Fund, most recently  at a Special  Meeting of Shareholders
held on January 12, 1993.  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 or shorten their  own terms or make  their terms of unlimited  duration
and appoint their own successors, provided that always

                                       34
<PAGE>
at  least a majority of the Trustees has been elected by the shareholders of the
Fund. Under certain circumstances, the Trustees may be removed by action of  the
Trustees.  The shareholders also have the right, under certain circumstances, to
remove the Trustees. The  voting rights of shareholders  are not cumulative,  so
that  holders of more than 50 percent of  the shares voting can, if they choose,
elect all Trustees  being selected, while  the holders of  the remaining  shares
would be unable to elect any Trustees.

    The  Declaration of Trust permits the  Trustees to authorize the creation of
additional series  of  shares  (the  proceeds of  which  would  be  invested  in
separate,  independently managed  portfolios) and  additional classes  of shares
within any  series (which  would be  used  to distinguish  among the  rights  of
different categories of shareholders, as might be required by future regulations
or  other unforeseen circumstances).  However, the Trustees  have not authorized
any such additional series or classes of shares.

    The Declaration of Trust further provides that no Trustee, officer, employee
or agent of  the Fund is  liable to  the Fund or  to a shareholder,  nor is  any
Trustee,  officer, employee or  agent liable to any  third persons in connection
with the affairs of the Fund, except  as such liability may a rise from  his/her
or  its  own  bad  faith, willful  misfeasance,  gross  negligence,  or reckless
disregard of his  duties. It  also provides that  all third  persons shall  look
solely  to the  Fund property for  satisfaction of claims  arising in connection
with the affairs  of the Fund.  With the exceptions  stated, the Declaration  of
Trust  provides that  a Trustee,  officer, employee or  agent is  entitled to be
indemnified against all liability in connection with the affairs of the Fund.

    The Trust shall be of unlimited  duration, subject to the provisions in  the
Declaration of Trust concerning termination by action of the shareholders or the
Trustees.

DEAN WITTER CONVERTIBLE SECURITIES TRUST
REPORT OF INDEPENDENT ACCOUNTANTS
- --------------------------------------------------------------------------------

To the Shareholders and Trustees of Dean Witter Convertible Securities Trust

    In  our  opinion,  the  accompanying statement  of  assets  and liabilities,
including the portfolio of investments, and the related statements of operations
and of changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Dean Witter Convertible  Securities
Trust, (the "Fund") at September 30, 1993, the results of its operations for the
year  then ended, the changes in its net assets for each of the two years in the
period then ended and the  financial highlights for each  of the seven years  in
the  period then  ended and  for the  period October  31, 1985  (commencement of
operations) through September  30, 1986, in  conformity with generally  accepted
accounting  principles.  These  financial  statements  and  financial highlights
(hereafter referred to as "financial statements") are the responsibility of  the
Fund's  management;  our  responsibility  is  to  express  an  opinion  on these
financial statements  based on  our audits.  We conducted  our audits  of  these
financial  statements in  accordance with generally  accepted auditing standards
which require that we plan and perform the audit to obtain reasonable  assurance
about  whether the  financial statements are  free of  material misstatement. An
audit includes examining, on a test  basis, evidence supporting the amounts  and
disclosures  in the  financial statements,  assessing the  accounting principles
used and significant estimates  made by management,  and evaluating the  overall
financial  statement presentation.  We believe  that our  audits, which included
confirmation of securities owned at  September 30, 1993, by correspondence  with
the  custodian and brokers, provide a reasonable basis for the opinion expressed
above.

1.  ORGANIZATION AND ACCOUNTING  POLICIES -- Dean  Witter Convertible Securities
Trust (the "Fund")  was organized on  May 21, 1985  as a Massachusetts  business
trust  and is registered  under the Investment  Company Act of  1940, as amended
(the "Act"), as a diversified, open-end management investment company. The  Fund
commenced operations on October 31, 1985.

    The following is a summary of significant accounting policies:

    A.  VALUATION OF INVESTMENTS  -- (1) an equity  portfolio security listed or
    traded on the New York  or American Stock Exchange  is valued at its  latest
    sale  price on that exchange (if there  were no sales that day, the security
    is valued at the latest bid  price); (2) all other portfolio securities  for
    which over-the-counter market quotations are readily available are valued at
    the  latest bid price; (3) when market quotations are not readily available,
    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  of the Fund's portfolio  securities
    may  be valued by an  outside pricing service approved  by the Trustees. The
    pricing service  utilizes a  matrix system  incorporating security  quality,
    maturity  and coupon as the evaluation model parameters, and/or research and
    evaluations by its  staff, including  review of  broker-dealer market  price
    quotations,  in determining  what it believes  is the fair  valuation of the
    portfolio securities valued by such pricing service; and (5) the fair  value
    of  short-term debt securities which  mature at a date  less than sixty days
    subsequent to the valuation date will be determined on an amortized cost  or
    amortized  value basis; other short-term debt securities will be valued on a
    mark-to-market basis until such  time as they reach  a maturity of 60  days,
    whereupon  they  will  be  valued at  amortized  value  unless  the Trustees
    determine such does not  reflect the securities' fair  value, in which  case
    these  securities will be  valued at their  fair value as  determined by the
    Trustees; and (6) the value of other assets will be determined in good faith
    at fair  value  under  procedures  established  by  and  under  the  general
    supervision of the Fund's Trustees.

    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  on the identified cost
    method. In  computing net  investment  income, the  Fund does  not  amortize
    premiums  or accrue discounts  on fixed income  securities in the portfolio,
    except those original issue discounts for which amortization is required for
    federal income tax purposes. Additionally, with respect to market  discount,
    a  portion of any  gain realized upon disposition  may be recharacterized as
    investment income.  Dividend income  is recorded  on the  ex-dividend  date.
    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 record date.

    E.  REPURCHASE AGREEMENTS -- The Fund's custodian takes possession on behalf
    of the  Fund  of  the  collateral  pledged  for  investments  in  repurchase
    agreements.  It is the policy of the Fund to value the underlying collateral
    daily on  a mark-to-market  basis  to determine  that the  value,  including
    accrued  interest, is  at least equal  to the repurchase  price plus accrued
    interest. In the event of default of the obligation to repurchase, the  Fund
    has  the  right  to  liquidate  the collateral  and  apply  the  proceeds in
    satisfaction of the obligation.

2. INVESTMENT  MANAGEMENT  AGREEMENT --  Pursuant  to an  Investment  Management
Agreement  (the "Agreement") with Dean Witter InterCapital Inc. (the "Investment

Division of Dean  Witter Reynolds  Inc. ("DWR"),  the Fund  pays its  Investment

3. PLAN OF DISTRIBUTION  -- Shares of  the Fund are  distributed by Dean  Witter
Distributors  Inc. (the "Distributor"), an  affiliate of the Investment Manager.
To compensate the Distributor for the services it provides and for the  expenses
it  bears  under the  Distribution Agreement,  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  the annual rate  of 1.0% 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

Amounts paid under the Plan are paid to the Distributor to compensate it for the
services it provides and the expenses it bears in the distribution of the Fund's

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.

by the  Distributor, but  not yet  recovered, may  be recovered  through  future
distribution  fees from the Fund and  contingent deferred sales charges from the
Fund's shareholders.
