                   account may be involuntarily redeemed if shares owned have a
                   net asset value of less than $100 or, if the account was
                   opened through EasyInvest (Service Mark), if after twelve

- -------------------------------------------------------------------------------
Risks              The value of the Fund's portfolio securities, and therefore
                   the Fund's net asset value per share, may increase or
                   decrease due to various factors, principally changes in
                   prevailing interest rates and the ability of the issuers of
                   the Fund's portfolio securities to pay interest and
                   principal on such obligations. The Fund may purchase
                   when-issued and delayed delivery securities (see page 8).
                   The Fund may also invest in futures and options, which may
                   be considered speculative in nature and which may involve
                   greater risks than those customarily assumed by certain
                   other investment companies which do not invest in such
                   instruments (see pages 8-10).
- -------------------------------------------------------------------------------
    

 The above is qualified in its entirety by the detailed information appearing
  elsewhere in the Prospectus and in the Statement of Additional Information.

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

    Dean Witter Tax-Exempt Securities Trust (the "Fund") is an open-end,
diversified management investment company incorporated in Maryland on December
13, 1979. The Fund reorganized as a trust of the type commonly known as a
"Massachusetts business trust" on April 30, 1987.

    Dean Witter InterCapital Inc. ("InterCapital" or the "Investment Manager"),
whose address is Two World Trade Center, New York, New York 10048, is the
Fund's Investment Manager. The Investment Manager, which was incorporated in
July, 1992, is a wholly-owned subsidiary of Dean Witter, Discover &
    

                                       4

<PAGE>

   
Co. ("DWDC"), a balanced financial services organization providing a broad 
range of nationally marketed credit and investment products. 

    InterCapital and its wholly-owned subsidiary, Dean Witter Services Company
Inc., serve in various investment management, advisory, management and
administrative capacities to a total of 102 investment companies, 30 of which
are listed on the New York Stock Exchange, with combined total net assets of
approximately $89.8 billion as of February 28, 1997. The Investment Manager
also manages portfolios of pension plans, other institutions and individuals
which aggregated approximately $3.2 billion at such date.

    On February 5, 1997, DWDC and Morgan Stanley Group Inc. announced that they
had entered into an Agreement and Plan of Merger, with the combined company to
be named Morgan Stanley, Dean Witter, Discover & Co. The business of Morgan
Stanley Group Inc. and its affiliated companies is providing a wide range of
financial services for sovereign governments, corporations, institutions and
individuals throughout the world. DWDC is the direct parent of InterCapital and
Dean Witter Distributors Inc., the Fund's distributor. It is currently
anticipated that the transaction will close in mid-1997. Thereafter,
InterCapital and Dean Witter Distributors Inc. will be direct subsidiaries of
Morgan Stanley, Dean Witter, Discover & Co.
    

    The Fund has retained the Investment Manager to provide administrative
services, manage its business affairs and manage the investment of the Fund's
assets, including the placing of orders for the purchase and sale of portfolio
securities. InterCapital has retained Dean Witter Services Company Inc. to
perform the aforementioned administrative services for the Fund.

    The Fund's Trustees review the various services provided by or under the
direction of the Investment Manager to ensure that the Fund's general
investment policies and programs are being properly carried out and that
administrative services are being provided to the Fund in a satisfactory
manner.

   
    As full compensation for the services and facilities furnished to the Fund
and for expenses of the Fund assumed by the Investment Manager, the Fund pays
the Investment Manager monthly compensation calculated daily at an annual rate
of 0.50% of the daily net assets of the Fund up to $500 million, scaled down at
various asset levels to 0.325% on net assets over $1.25 billion. For the fiscal
year ended December 31, 1996, the Fund accrued total compensation to the
Investment Manager amounting to 0.43% of the Fund's average daily net assets
and the Fund's total expenses amounted to 0.48% of the Fund's average daily net
assets.
    

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

    The investment objective of the Fund is to provide a high level of current
income which is exempt from federal income tax, consistent with the
preservation of capital. There is no assurance that this objective will be
achieved. This objective is fundamental and may not be changed without
shareholder approval. The Fund seeks to achieve its investment objective by
investing its assets in accordance with the following policies:

         1. At least 80% of the Fund's total assets will be invested in
    tax-exempt securities, except as stated in paragraph (5) below. Tax-exempt
    securities consist of Municipal Bonds and Municipal Notes ("Municipal
    Obligations") and Municipal Commercial Paper.

         2. At least 75% of the Fund's total assets will be invested in: (a)
    Municipal Bonds which are rated at the time of purchase within the three
    highest grades by Moody's Investors Service, Inc. ("Moody's") or Standard &
    Poor's Corporation ("S&P"); (b) Municipal Notes which at the time of
    purchase are rated in the two highest grades by Moody's or S&P, or, if not
    rated, have outstanding one or more issues of Municipal Bonds rated as set
    forth in clause (a) of this paragraph; and (c) Municipal Commer-

                                       5
<PAGE>

    cial Paper which at the time of purchase are rated P-1 by Moody's or A-1 
    by S&P. 

         3. Up to 25% of the Fund's total assets may be invested in tax-exempt
    securities which are not rated by Moody's or S&P or, if rated, are not
    within the rating categories of Moody's or S&P stated in paragraph (2)
    above.

         4. In accordance with the current position of the staff of the
    Securities and Exchange Commission, tax-exempt securities which are subject
    to the federal alternative minimum tax for individual shareholders will not
    be included in the 80% total described in paragraph 1 above. (See
    "Dividends, Distributions and Taxes," below.) As such, the remaining 20% of
    the Fund's total assets may be invested in tax-exempt securities subject to
    the alternative minimum tax.

         5. Inclusive of paragraph 4 above, up to 20% of the Fund's total
    assets may be invested in taxable money market instruments under any one or
    more of the following circumstances: (a) pending investment of proceeds of
    sale of Fund shares or of portfolio securities; (b) pending settlement of
    purchases of portfolio securities; and (c) to maintain liquidity for the
    purpose of meeting anticipated redemptions. In addition, the Fund may
    temporarily invest more than 20% of its total assets in taxable securities,
    or in tax-exempt securities subject to the federal alternative minimum tax
    for individual shareholders, to maintain a "defensive" posture when, in the
    opinion of the Investment Manager, it is advisable to do so because of
    market conditions. The types of taxable securities in which the Fund may
    temporarily invest are limited to the following short-term fixed-income
    securities (maturing in one year or less from the time of purchase): (i)
    obligations of the United States Government, its agencies,
    instrumentalities or authorities; (ii) commercial paper rated P-1 by
    Moody's or A-1 by S&P; (iii) certificates of deposit of domestic banks with
    assets of $1 billion or more; and (iv) repurchase agreements with respect
    to any of the foregoing portfolio securities.

    Municipal Obligations are debt obligations of states, cities,
municipalities and municipal agencies which generally have maturities, at the
time of their issuance, of either one year or more (Bonds) or from six months
to three years (Notes). Municipal Commercial Paper refers to short-term
obligations of municipalities. Any Municipal Obligation which depends directly
or indirectly on the credit of the Federal Government shall be considered to
have a rating of Aaa/AAA. The Fund may purchase Municipal Obligations which had
originally been issued by the same issuer as two separate series of the same
issue with different interest rates, but which are now linked together to form
one series.

    While the Fund may invest up to 25% of its total assets in Municipal
Obligations which are unrated or, if rated, are not within the three highest
Bond rating categories of Moody's or S&P or the two highest Note rating
categories of Moody's or S&P, the Fund does not intend to invest in Municipal
Bonds which are rated below either Baa by Moody's or BBB by S&P (the lowest
ratings considered investment grade) or, if not rated, are deemed by the
Investment Manager to be below investment grade, in amounts exceeding 5% of its
total assets. Investments in Municipal Bonds rated either Baa by Moody's or BBB
by S&P may have speculative characteristics and, therefore, changes in economic
conditions or other circumstances are more likely to weaken their capacity to
make principal and interest payments than would be the case with investments in
securities with higher credit ratings. Municipal Bonds rated below investment
grade may not currently be paying any interest and may have extremely poor
prospects of ever attaining any real investment standing.

    The two principal classifications of Municipal Obligations and Commercial
Paper are "general obligation" and "revenue" obligations or commercial paper.
General obligation bonds, notes or commer-

                                       6
<PAGE>

cial paper are secured by the issuer's pledge of its faith, credit and taxing 
power for the payment of principal and interest. Issuers of general 
obligation bonds, notes or commercial paper include a state, its counties, 
cities, towns and other government units. Revenue bonds, notes or commercial 
paper are payable from the revenues derived from a particular facility or 
class of facilities or, in some cases, from specific revenue sources. Revenue 
bonds, notes or commercial paper are issued for a wide variety of purposes, 
including the financing of electric, gas, water and sewer systems and other 
public utilities; industrial development and pollution control facilities; 
single and multi-family housing units; public buildings and facilities; air 
and marine ports; transportation facilities such as toll roads, bridges and 
tunnels; and health and educational facilities such as hospitals and 
dormitories. They rely primarily on user fees to pay debt service, although 
the principal revenue source is often supplemented by additional security 
features which are intended to enhance the creditworthiness of the issuer's 
obligations. In some cases, particularly revenue bonds issued to finance 
housing and public buildings, a direct or implied "moral obligation" of a 
governmental unit may be pledged to the payment of debt service. In other 
cases, a special tax or other charge may augment user fees. 

    Included within the revenue category are participations in lease
obligations or installment purchase contracts (hereinafter collectively called
"lease obligations") of municipalities. State and local governments issue lease
obligations to acquire equipment and facilities.

    Lease obligations may have risks not normally associated with general
obligation or other revenue bonds. Leases and installment purchase or
conditional sale contracts (which may provide for title to the leased asset to
pass eventually to the issuer) have developed as a means for governmental
issuers to acquire property and equipment without the necessity of complying
with the constitutional and statutory requirements generally applicable for the
issuance of debt. Certain lease obligations contain "non-appropriation" clauses
that provide that the governmental issuer has no obligation to make future
payments under the lease or contract unless money is appropriated for such
purpose by the appropriate legislative body on an annual or other periodic
basis. Consequently, continued lease payments on those lease obligations
containing "non-appropriation" clauses are dependent on future legislative
actions. If such legislative actions do not occur, the holders of the lease
obligation may experience difficulty in exercising their rights, including
disposition of the property.

   
    Lease obligations represent a type of financing that may not have the depth
of marketability associated with more conventional municipal obligations, and,
as a result, certain of such lease obligations may be considered illiquid
securities. To determine whether or not the Fund will consider such securities
to be illiquid (the Fund may not invest more than ten percent of its net assets
in illiquid securities), the Trustees of the Fund have established guidelines
to be utilized by the Fund in determining the liquidity of a lease obligation.
The factors to be considered in making the determination include: 1) the
frequency of trades and quoted prices for the obligation; 2) the number of
dealers willing to purchase or sell the security and the number of other
potential purchasers; 3) the willingness of dealers to undertake to make a
market in the security; and 4) the nature of the marketplace trades, including,
the time needed to dispose of the security, the method of soliciting offers,
and the mechanics of the transfer.
    

    The interest rates payable on certain Municipal Bonds and Municipal Notes
are not fixed and may fluctuate based upon changes in market rates. Municipal
obligations of this type are called "variable rate" obligations. The interest
rate payable on a variable rate obligation is adjusted either at predesignated
periodic intervals or whenever there is a change in the market rate of interest
on which the interest rate payable is based.

    The foregoing percentage and rating policies apply at the time of
acquisition of a security based on the last previous determination of the
Fund's net asset value. Any subsequent change in any rating by a rating service
or change in percentages result-

                                       7
<PAGE>

ing from market fluctuations or other changes in the Fund's total assets will 
not require elimination of any security from the Fund's portfolio until such 
time as the Investment Manager determines that it is practicable to sell the 
security without undue market or tax consequences to the Fund. 

    The ratings assigned by Moody's and S&P represent their opinions as to the
quality of the securities which they undertake to rate (see the Appendix to the
Statement of Additional Information). It should be emphasized, however, that
the ratings are general and not absolute standards of quality.

    When-Issued and Delayed Delivery Securities. The Fund may purchase
tax-exempt securities on a when-issued or delayed delivery basis; i.e.,
delivery and payment can take place a month or more after the date of the
transaction. These securities are subject to market fluctuation and no interest
accrues to the purchaser prior to settlement. At the time the Fund makes the
commitment to purchase such securities, it will record the transaction and
thereafter reflect the value, each day, of such securities in determining its
net asset value. An increase in the percentage of the Fund's assets committed
to the purchase of securities on a when-issued or delayed delivery basis may
increase the volatility of the Fund's net asset value.

    Zero Coupon Securities. A portion of the fixed-income securities purchased
by the Fund may be zero coupon securities. Such securities are purchased at a
discount from their face amount, giving the purchaser the right to receive
their full value at maturity. The interest earned on such securities is,
implicitly, automatically compounded and paid out at maturity. While such
compounding at a constant rate eliminates the risk of receiving lower yields
upon reinvestment of interest if prevailing interest rates decline, the owner
of a zero coupon security will be unable to participate in higher yields upon
reinvestment of interest received on interest-paying securities if prevailing
interest rates rise.

    A zero coupon security pays no interest to its holder during its life.
Therefore, to the extent the Fund invests in zero coupon securities, it will
not receive current cash available for distribution to shareholders. In
addition, zero coupon securities are subject to substantially greater price
fluctuations during periods of changing prevailing interest rates than are
comparable securities which pay interest on a current basis. Current federal
tax law requires that a holder (such as the Fund) of a zero coupon security
accrue a portion of the discount at which the security was purchased as income
each year even though the Fund receives no interest payments in cash on the
security during the year.

RISK CONSIDERATIONS AND INVESTMENT PRACTICES 

   
    The value of the Fund's portfolio securities and, therefore, the Fund's net
asset value per share, may increase or decrease due to various factors,
principally changes in prevailing interest rates and the ability of the issuers
of the Fund's portfolio securities to pay interest and principal on such
obligations on a timely basis. Generally, a rise in interest rates will result
in a decrease in the Fund's net asset value per share, while a drop in interest
rates will result in an increase in the Fund's net asset value per share. The
Fund's yield will also vary based on the yield of the Fund's portfolio
securities.
    

    Futures Contracts and Options on Futures. The Fund may enter into financial
futures contracts ("futures contracts"), options on such futures and municipal
bond index futures contracts for hedging purposes. The Fund may sell a futures
contract or a call option thereon or purchase a put option on such futures
contract, if the Investment Manager anticipates interest rates to rise, as a
hedge against a decrease in the value of the Fund's portfolio securities. If
the Investment Manager anticipates that interest rates will decline, the Fund
may purchase a futures contract or a call option thereon or sell a put option
on such futures contract, to protect against an increase in the price of the
securities the Fund intends to purchase. These futures contracts and related
options thereon will be used only as a hedge against anticipated interest rate
changes. A futures contract sale creates an obligation by the Fund, as seller,
to deliver the specific type of instrument

                                       8
<PAGE>

called for in the contract at a specified future time for a specified price. 
A futures contract purchase creates an obligation by the Fund, as purchaser, 
to take delivery of the specific type of financial instrument at a specified 
future time at a specified price. The specific securities delivered or taken, 
respectively, at settlement date, would not be determined until or near that 
date. The determination would be in accordance with the rules of the exchange 
on which the futures contract sale or purchase was effected. 

    Although the terms of futures contracts specify actual delivery or receipt
of securities, in most instances the contracts are closed out before the
settlement date without the making or taking of delivery of the securities.
Closing out of a futures contract is effected by entering into an offsetting
purchase or sale transaction.

    Unlike a futures contract, which requires the parties to buy and sell a
security on a set date, an option on a futures contract entitles its holder to
decide on or before a future date whether to enter into such a contract (a long
position in the case of a call option and a short position in the case of a put
option). If the holder decides not to enter into the contract, the premium paid
for the option on the contract is lost. Since the value of the option is fixed
at the point of sale, there are not daily payments of cash to reflect the
change in the value of the underlying contract as there are by a purchaser or
seller of a futures contract. The value of the option does change and is
reflected in the net asset value of the Fund.

    A risk in employing futures contracts to protect against the price
volatility of portfolio securities is that the prices of securities subject to
futures contracts may correlate imperfectly with the behavior of the cash
prices of the Fund's portfolio securities. The risk of imperfect correlation
may be increased by the fact that the Fund will invest in futures contracts on
taxable securities and there is no guarantee that the prices of taxable
securities will move in a similar manner to the prices of tax-exempt
securities. The correlation may be distorted by the fact that the futures
market is dominated by short-term traders seeking to profit from the difference
between a contract or security price objective and their cost of borrowed
funds. Such distortions are generally minor and would diminish as the contract
approached maturity.

    Another risk is that the Fund's manager could be incorrect in its
expectations as to the direction or extent of various interest rate movements
or the time span within which the movements take place. For example, if the
Fund sold futures contracts for the sale of securities in anticipation of an
increase in interest rates, and then interest rates went down instead, causing
bond prices to rise, the Fund would lose money on the sale.

    In addition to the risks that apply to all options transactions (see the
Statement of Additional Information for a description of the characteristics
of, and the risks of investing in, options on debt securities), there are
several special risks relating to options on futures; in particular, the
ability to establish and close out positions on options on futures will be
subject to the development and maintenance of a liquid secondary market. It is
not certain that this market will develop or be maintained.

    Municipal Bond Index Futures. The Fund may utilize municipal bond index
futures contracts and options thereon for hedging purposes. The Fund's
strategies in employing such contracts will be similar to that discussed above
with respect to financial futures and options thereon. A municipal bond index
is a method of reflecting in a single number the market value of many different
municipal bonds and is designed to be representative of the municipal bond
market generally. The index fluctuates in response to changes in the market
values of the bonds included within the index. Unlike futures contracts on
particular financial instruments, transactions in futures on a municipal bond
index will be settled in cash, if held until the close of trading in the
contract. However, like any other futures contract, a position in the contract
may be closed out by purchase or sale of an offsetting contract for the same
delivery month prior to expiration of the contract.

                                       9
<PAGE>

    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. 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.

    For a discussion of the risks of certain types of Municipal Obligations,
such as lease obligations, see above in "Investment Objective and Policies."

PORTFOLIO MANAGEMENT 

   
    The Fund is actively managed by the Investment Manager with a view to
achieving the Fund's investment objective. In determining which securities to
purchase for the Fund or hold in the Fund's portfolio, the Investment Manager
will rely on information from various sources, including research, analysis and
appraisals of brokers and dealers, including Dean Witter Reynolds Inc. ("DWR"),
a broker-dealer affiliate of InterCapital, the views of Trustees of the Fund
and others regarding economic developments and interest rate trends, and the
Investment Manager's own analysis of factors it deems relevant. The Fund is
managed within InterCapital's Tax-Exempt Group, which manages 40 tax-exempt
municipal funds and fund portfolios, with approximately $10.8 billion in assets
as of February 28, 1997. James F. Willison, Senior Vice President of
InterCapital and Manager of Inter Capital's Municipal Fixed Income Group and
Joseph R. Arcieri, Vice President of InterCapital and a member of
InterCapital's Municipal Fixed Income Group, have been the primary portfolio
co-managers of the Fund since its inception and February, 1997, respectively,
and have been portfolio managers at InterCapital for over five years.
    

    Securities are purchased and sold principally in response to the Investment
Manager's current evaluation of an issuer's ability to meet its debt
obligations in the future, and the Investment Manager's current assessment of
future changes in the levels of interest rates on tax-exempt securities of
varying maturities. Securities purchased by the Fund are, generally, sold by
dealers acting as principal for their own accounts. 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 will incur underwriting discount costs
(on underwritten securities) commensurate with its portfolio turnover rate.
Additionally, see "Dividends, Distributions and Taxes" for a discussion of the
tax policy of the Fund. 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 which
have been adopted by the Fund as fundamental policies. Under the Investment
Company Act of 1940, as amended (the "Act"), a fundamental policy may not be
changed without the vote of a majority of the outstanding voting securities of
the Fund, as defined in the Act.

    For purposes of the following restrictions: (a) an "issuer" of a security
is the entity whose assets and revenues are committed to the payment of
interest and principal on that particular security, provided that the guarantee
of a security will be considered a separate security, and provided further that
a guarantee of a security shall not be deemed to be a

                                       10
<PAGE>

security issued by the guarantor if the value of all securities issued or 
guaranteed by the guarantor and owned by the Fund does not exceed 10% of the 
value of the total assets of the Fund; (b) a "taxable security" is any 
security the interest on which is subject to federal income tax; and (c) all 
percentage limitations apply immediately after a purchase or initial 
investment, and any subsequent change in any applicable percentage resulting 
from market fluctuations or other changes in the Fund's total assets does not 
require elimination of any security from the portfolio. 

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 taxable debt securities or any
one issuer (other than obligations issued, or guaranteed as to principal and
interest, by the United States Government, its agencies or instrumentalities).

    3. Invest more than 25% of the value of its total assets in securities of
issuers in any one industry. This restriction does not apply to obligations
issued or guaranteed by the United States Government, its agencies or
instrumentalities or to cash equivalents (industrial development and pollution
control bonds are grouped into industries based upon the business in which the
issuers of such obligations are engaged).

    4. Invest more than 5% of the value of its total assets in taxable
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.

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 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 Tax-Exempt
Securities Trust, directly to Dean Witter Trust Company (the "Transfer Agent")
at P.O. Box 1040, Jersey City, N.J. 07303 or by contacting a DWR or other
Selected Broker-Dealer account executive. The minimum initial purchase in the
case of investments through EasyInvest (Service Mark), an automatic purchase
plan (see "Shareholder Services"), is $100, provided that the schedule of
automatic investments will result in investments totalling at least $1,000
within the first twelve months.

    In the case of purchases made pursuant to systematic payroll deduction
plans (including individual retirement plans), the Fund, in its discretion, may
accept such purchases without regard to any minimum amounts which would
otherwise be required if the Fund has reason to believe that additional
purchases will increase the amount of the purchase of shares in all accounts
under such plans to at least $1,000. Certificates for shares purchased will not
be issued unless a request is made by the shareholder in writing to the
Transfer Agent. The offering price will be the net asset value per share next
determined following receipt of an order (see "Determination of Net Asset
Value" below), plus a sales charge (expressed as a percentage of the offering
price) on a single transaction as shown in the following table:

</TABLE>

   Upon notice to all Selected Broker-Dealers, the Distributor may reallow up 
to the full applicable sales charge as shown in the above schedule during 
periods specified in such notice. During periods when substantially the 
entire sales charge is reallowed, such Selected Broker-Dealers may be deemed 
to be underwriters as that term is defined in the Securities Act of 1933, as 
amended. 

    The above schedule of sales charges is applicable to purchases in a single
transaction by, among others: (a) an individual; (b) an individual, his or her
spouse and their children under the age of 21 purchasing shares for his or her
own accounts; (c) a trustee or other fiduciary purchasing shares for a single
trust estate or a single fiduciary account; (d) a pension, profit-sharing or
other employee benefit plan qualified or non-qualified under Section 401 of the
Internal Revenue Code; (e) tax-exempt organizations enumerated in Section
501(c)(3) or (13) of the Internal Revenue Code; (f) employee benefit plans
qualified under Section 401 of the Internal Revenue Code of a single employer
or of employers who are "affiliated persons" of each other within the meaning
of Section 2(a)(3)(c) of the Act; or (g) any other organized group of persons,
whether incorporated or not, provided the organization has been in existence
for at least six months and has some purpose other than the purchase of
redeemable securities of a registered investment company at a discount.

    Sales personnel are compensated for selling shares of the Fund at the time
of their sale by the Distributor and/or Selected Broker-Dealer. In addition,
some sales personnel of the Selected Broker-Dealer will receive various types
of non-cash compensation as special sales incentives, including trips,
educational and/or business seminars and merchandise.

    Shares of the Fund are sold through the Distributor on a normal three
business day settlement basis; that is, payment generally is due on or before
the third business day (settlement date) after the order is placed with the
Distributor. Shares of the Fund purchased through the Distributor are entitled
to dividends beginning on the next business day following settlement date.
Since DWR and other Selected Broker-Dealers forward investors' funds on
settlement date, they will benefit from the temporary use of the funds where
payment is made prior thereto. Shares purchased through the Transfer Agent are
entitled to dividends beginning on the next business day following receipt of
an order. As noted above, orders placed directly with the Transfer Agent must
be accompanied by payment. Investors will be entitled to receive capital gains
distributions if their order is received by the close of business on the day
prior to the record date for such distributions. The Fund and/or the
Distributor reserve the right to reject any purchase order.

    Analogous Dean Witter Funds. The Distributor and the Investment Manager
serve in the same capacities for Dean Witter National Municipal Trust, an
open-end investment company with investment objectives and policies similar to
those of the Fund. Unlike the Fund, however, shares of Dean Witter National
Municipal Trust are offered to the public at net asset value, with a contingent
deferred sales charge assessed upon redemptions within three years of purchase,
as well as an annual Rule 12b-1 distribution fee, rather than a sales charge
imposed at the time of purchase. These two Dean Witter Funds have differing
fees and expenses, which will affect performance. Investors who would like to
receive a prospectus for Dean Witter National Municipal Trust should call the
telephone numbers listed on the front cover of this Prospectus, or may call
their account executive for additional information.

REDUCED SALES CHARGES 

    Combined Purchase Privilege. Investors may have the benefit of reduced
sales charges in accordance with the above schedule by combining purchases of
shares of the Fund in single transactions with the purchase of shares of Dean
Witter High Yield Securities Inc. and of Dean Witter Funds which are sold with
a contingent deferred sales charge ("CDSC funds"). The sales charge payable on
the purchase of shares of the Fund and Dean Witter High Yield Securities Inc.
will be at their respective rates applicable to the total amount of the
combined concurrent purchases of the Fund, Dean Witter High Yield Securities
Inc. and CDSC funds.

    Right of Accumulation. The above persons and entities may also benefit from
a reduction of the sales charges in accordance with the above schedule if the
cumulative net asset value of shares purchased in a single transaction,
together with shares previously purchased (including shares of Dean Witter High
Yield Securities Inc. and CDSC funds, and of certain Dean Witter funds acquired
in exchange for shares of such funds) which are held at the time of such
transaction, amounts to $25,000 or more.

    The Distributor must be notified by DWR or other Selected Broker-Dealer or
the shareholder at the time a purchase order is placed that the purchase
qualifies for the reduced charge under the Right of Accumulation. Similar
notification must be made in writing by the dealer or shareholder when such an
order is placed by mail. The reduced sales charge will not be granted if: (a)
such notification is not furnished at the time of the order; or (b) a review of
the records of the Selected Broker-Dealer or the Transfer Agent fails to
confirm the investor's represented holdings.

    Letter of Intent. The foregoing schedule of reduced sales charges will also
be available to investors who enter into a written Letter of Intent providing
for the purchase, within a thirteen-month period, of shares of the Fund from
DWR or another Selected Broker-Dealer. The cost of shares of the Fund or shares
of Dean Witter High Yield Securities Inc. which were previously purchased at a
price including a front-end sales charge during the 90-day period prior to the
date of receipt by the Distributor of the Letter of Intent, or of shares of
other Dean Witter Funds acquired in exchange for shares of such funds acquired
during such period at a price including a front-end sales charge, which are
still owned by the shareholder, may also be included in determining the
applicable reduction.

DETERMINATION OF NET ASSET VALUE 

    The net asset value per share of the Fund is determined once daily at 4:00
p.m., New York time, on each day that the New York Stock Exchange is open (or,
on days when the New York Stock Exchange closes prior to 4:00 p.m., at such
earlier time), by taking the value of all assets of the Fund, subtracting its
liabilities, dividing by the number of shares outstanding and adjusting to the
nearest cent. The 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.

   
    Portfolio securities (other than short-term taxable debt securities,
futures and options) are valued for the Fund by an outside independent pricing
service approved by the Fund's Trustees. The service may utilize a computerized
grid matrix of tax-exempt securities and evaluations by its staff in
determining what it believes is the fair value of the Fund's portfolio
securities. The Board believes that timely and reliable market quotations are
generally not readily available to the Fund for purposes of valuing tax-exempt
securities and that the valuations supplied by the pricing services are more
likely to approximate the fair value of such securities.

    Short-term taxable debt securities with remaining maturities of 60 days or
less at time of purchase are valued at amortized cost, unless the Board
determines such does not reflect the securities' market value, in which case
these securities will be valued at their fair value as determined by the Board
of Trustees. Other taxable short-term debt securities with maturities of more 
than 60 days 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 cost 
using their value on the
    

                               13           
<PAGE>

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
market value as determined by the Board of Trus tees. Listed options on debt
securities are valued at the latest sale price on the exchange on which they
are listed unless no sales of such options have taken place that day, in which
case, they will be valued at the mean between their closing bid and asked
prices. Unlisted options on debt securities are valued at the mean between
their latest bid and asked price. Futures are valued at the latest sale price
on the commodities exchange on which they trade unless the Board of Trustees
determines that such price does not reflect their fair value, in which case
they will be valued at their fair market value as determined by the Board of
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 Board of Trustees.

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

   
   Automatic Investment of Dividends and Distri-butions. 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. Each purchase of shares of 
the Fund is made upon the condition that the Transfer Agent is thereby 
automatically appointed as agent of the investor to receive all dividends and 
capital gains distributions on shares owned by the investor. Such dividends 
and distributions will be paid, at the net asset value per share (without 
sales charge), in shares of the Fund (or in cash if the shareholder so 
requests) on the monthly payment date, which will be no later than the last 
business day of the month for which the dividend or distribution is payable. 
Processing of dividend checks begins immediately following the monthly 
payment date. Shareholders who have requested to receive dividends in cash 
will normally receive their monthly dividend checks during the first ten days 
of the following month. 
    

   EasyInvest (Service Mark). Shareholders may subscribe to EasyInvest, an 
automatic purchase plan which pro-vides for any amount from $100 to $5,000 to 
be transferred automatically from a checking or savings account, on a 
semi-monthly, monthly or quarterly basis, to the Transfer Agent for 
investment in shares of the Fund (see "Purchase of Fund Shares" and 
"Redemptions and Repurchases--Involuntary Redemption"). 

   Systematic Withdrawal Plan. A 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 plan provides for 
monthly or quarterly (March, June, September, December) checks in any dollar 
amount, not less than $25, or in any whole percentage of the account balance, 
on an annualized basis. 

   Withdrawal plan payments should not be considered as dividends, yields or 
income. If periodic withdrawal plan payments continuously exceed net 
investment income and net capital gains, the shareholder's original 
investment will be correspondingly reduced and ultimately exhausted. 

   Each withdrawal constitutes a redemption of shares and any gain or loss 
realized must be recognized for federal income tax purposes. Although the 
shareholder may make additional investments of $2,500 or more under the 
Systematic Withdrawal Plan, withdrawals made concurrently with purchases of 
additional shares are inadvisable because of the sales charges applicable to 
the purchase of additional shares. 

   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. 

                                       14
<PAGE>

   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 front-end (at time of purchase) sales 
charge ("FESC" funds), Dean Witter Funds sold with a contingent deferred 
sales charge ("CDSC funds"), five Dean Witter Funds which are money market 
funds and Dean Witter Short-Term U.S. Treasury Trust, Dean Witter Short-Term 
Bond Fund, Dean Witter Limited Term Municipal Trust, Dean Witter Balanced 
Income Fund, Dean Witter Balanced Growth Fund and Dean Witter Intermediate 
Term U.S. Treasury Trust (the foregoing eleven non-CDSC or FESC funds are 
hereinafter collectively referred to in this section as the "Exchange 
Funds"). Exchanges may be made after the shares of the Fund acquired by 
purchase (not by exchange or dividend reinvestment) have been held for thirty 
days. There is no holding period for exchanges of shares acquired by exchange 
or dividend reinvestment. However, shares of CDSC funds, including shares 
acquired in exchange for shares of FESC funds, may not be exchanged for 
shares of FESC funds. Thus, shareholders who exchange their Fund shares for 
shares of CDSC funds may subsequently exchange those shares for shares of 
other CDSC funds or money market funds but may not reacquire FESC fund shares 
by exchange. 

   An exchange to another FESC fund, to a CDSC fund, or to any Exchange Fund 
that is not a money market fund is on the basis of the next calculated net 
asset value per share of each fund after the exchange order is received. When 
exchanging into a money market fund from the Fund, shares of the Fund are 
redeemed out of the Fund at their next calculated net asset value and the 
proceeds of the redemption are used to purchase shares of the money market 
fund at their net asset value determined the following business day. 
Subsequent exchanges between any of the Exchange Funds, FESC funds and CDSC 
funds can be effected on the same basis (except that CDSC fund shares may not 
be exchanged for shares of FESC funds). Shares of a CDSC fund acquired in 
exchange for shares of an FESC fund (or in exchange for shares of other Dean 
Witter Funds for which shares of an FESC fund have been exchanged) are not 
subject to any contingent deferred sales charge 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 shoud be 
aware that the Fund and each of the other Dean Witter Funds may in their 
discretion limit or otherwise restrict the number of times this Exchange 
Privilege may be exercised by any investor. Any such restriction will be made 
by the Fund on a prospective basis only, upon notice to the shareholder not 
later than ten days following such shareholder's most recent exchange. 

   The Exchange Privilege may be terminated or revised at any time by the 
Fund and/or any of such Dean Witter Funds for which shares of the Fund may be 
exchanged, upon such notice as may be required by applicable regulatory 
agencies. Shareholders maintaining margin accounts with DWR or another 
Selected Broker-Dealer are referred to their account executive regarding 
restrictions on exchange of shares of the Fund pledged in their margin 
account. 

   The current prospectus for each fund describes its investment objectives and
policies, and shareholders should obtain one and read it carefully before
investing. Exchanges are subject to the minimum investment requirement and
other conditions imposed by each fund. In the case of any

                               15           
<PAGE>

shareholder holding a share certificate or certificates, no exchanges may be
made until the share certificate(s) have been received by the Transfer Agent
and deposited in the shareholder's account. An exchange will be treated for
federal income tax purposes as a redemption or repurchase of shares, on which
the shareholder may realize a capital gain or loss. However, the ability to
deduct capital losses on an exchange is limited in situations where there is an
exchange of shares within ninety days after the shares are purchased. There are
also limits on the deduction of losses after the payment of exempt-interest
dividends for shares held for less than six months (see "Dividends,
Distributions and Taxes"). The Exchange Privilege is only available in states
where an exchange may legally be made.

   If DWR or another Selected Broker-Dealer is the current dealer of record 
and its account numbers are part of the account information, shareholders may 
initiate an exchange of shares of the Fund for shares of any of the Dean 
Witter Funds (for which the Exchange Privilege is available) pursuant to this 
Exchange Privilege by contacting their DWR or other Selected Broker-Dealer 
account executive (no Exchange Privilege Authorization Form is required). 
Other shareholders (and those shareholders who are clients of DWR or another 
Selected Broker-Dealer but who wish to make exchanges directly by writing or 
telephoning the Transfer Agent) must complete and forward to the Transfer 
Agent an Exchange Privilege Authorization form, copies of which may be 
obtained from the Transfer Agent, to initiate an exchange. If the 
Authorization Form is used, exchanges may be made by contacting the Transfer 
Agent at (800) 869-NEWS (toll-free). The Fund will employ reasonable 
procedures to confirm that exchange instructions communicated over the 
telephone are genuine. Such procedures may include requiring various forms of 
personal identification such as name, mailing address, social security or 
other tax identification number and DWR or other Selected Broker-Dealer 
account number (if any). Telephone instructions may also be recorded. If such 
procedures are not employed, the Fund may be liable for any losses due to 
unauthorized or fraudulent instructions. 

   Telephone exchange instructions will be accepted if received by the 
Transfer Agent between 9:00 a.m. and 4:00 p.m. New York time, on any day the 
New York Stock Exchange is open. Any shareholder wishing to make an exchange 
who has previously filed an Exchange Privilege Authorization Form and who is 
unable to reach the Fund by telephone should contact his or her DWR or other 
Selected Broker-Dealer account executive, if appropriate, or make a written 
exchange request (see "Redemptions and Repurchases"). 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. 

   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. Shares of the Fund can be redeemed for cash at any time at the 
net asset value per share next determined (without any redemption or other 
charge). If shares are held in a shareholder's account without a share 
certificate, a written request for redemption is required. If certificates 
are held by the shareholder(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. 

   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 

                                       16
<PAGE>

repurchased by DWR and other Selected Broker-Dealers upon the telephonic
request of the shareholder. The repurchase price is the net asset value next
determined (see "Purchase of Fund Shares--Determination of Net Asset Value")
after such repurchase order is received by DWR or other Selected Broker-Dealer.
Payment for shares repurchased may be made by the Fund to the Distributor for
the account of the shareholder. The offers by DWR and other Selected
Broker-Dealers to repurchase shares from shareholders may be suspended 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 at times when normal trading is not taking place on the New York 
Stock Exchange. If the shares to be redeemed have recently been purchased by 
check, payment of the redemption proceeds may be delayed for the minimum time 
needed to verify that the check used for investment has been honored (not 
more than fifteen days from the time of 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. 

   Reinstatement Privilege. A shareholder who has had his or her share 
redeemed or repurchased and has not previously exercised this reinstatement 
privilege may, within 30 days after the date of the redemption or repurchase, 
reinstate any portion or all of the proceeds of such redemption or repurchase 
in shares of the Fund at their net asset value (without a sales charge) next 
determined after a reinstatement request, to gether with the proceeds, is 
received by the Transfer Agent. 

   Involuntary Redemption. The Fund reserves the right, on sixty days notice, 
to redeem at net asset value, the shares of any shareholder whose shares have 
a value of less than $100 as a result of redemptions or repurchases, or such 
lesser amount as may be fixed by the Board of Trustees or, in the case of an 
account opened through EasyInvest, if after twelve months the shareholder has 
invested less than $1,000 in the account. However, before the Fund redeems 
such shares and sends the proceeds to the shareholder, it will notify the 
shareholder that the value of the shares is less than the applicable amount 
and allow the shareholder to make an additional investment in an amount which 
will increase the value of the account to at least the applicable amount 
before the redemption is processed. No charge will be imposed on any 
involuntary redemption. 

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

   Dividends and Distributions. The Fund declares dividends from net 
investment income on each day the New York Stock Exchange is open for 
business (see "Purchase of Fund Shares"). Such dividends are paid monthly. 
The Fund intends to distribute all of the Fund's net investment income on an 
annual basis. 

   The Fund will distribute at least once each year all net realized 
short-term capital gains in excess of any realized net long-term capital 
losses, if any. The Fund intends to distribute all of its realized net 
long-term capital gains, if any, in excess of any realized net short-term 
capital losses and any available net capital loss carryovers, at least once 
per fiscal year, although it may elect to retain all or part of such gains 
for reinvestment. Taxable capital gains may be generated by the sale of 
portfolio securities and by transactions in options and futures contracts 
engaged in by the Fund. All dividends and capital 

                                      17
<PAGE>

gains distributions will be paid in additional Fund shares (without sales
charge) and automatically credited to the shareholder's account without
issuance of a share certificate unless the shareholder requests in writing that
all dividends be paid in cash and such request is received by the close of
business on the day prior to the record date for such distributions (see
"Shareholder Services--Automatic Investment of Dividends and Distributions").
Any dividends declared in the last quarter of any calendar year which are paid
in the following calendar year prior to February 1 will be deemed received by
the shareholder in the prior calendar year.

   Taxes. Because the Fund intends to distribute all of its net investment 
income and capital gains to shareholders and intends to 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. 

   The Fund intends to qualify to pay "exempt-interest dividends" to its 
shareholders by maintaining, as of the close of each quarter of its taxable 
year, at least 50% of the value of its total assets in tax-exempt securities. 
If the Fund satisfies such requirement, distributions from net investment 
income to shareholders, whether taken in cash or reinvested in additional 
shares, will be excludable from gross income for federal income tax purposes 
to the extent net investment income is represented by interest on tax-exempt
securities. Exempt-interest dividends are included, however, in determining
what portion, if any, of a person's Social Security benefits are subject to
federal income tax. The Internal Revenue Code may subject interest received on
certain otherwise tax-exempt securities to an alternative minimum tax. This
alternative minimum tax may be incurred due to interest received on certain
"private activity bonds" (in general, bonds that benefit non-government
entities) issued after August 7, 1986 which, although tax-exempt, are used for
purposes other than those generally performed by government units (e.g., bonds
used for commercial or housing purposes). Income received on such bonds is
classified as a "tax preference item," under the alternative minimum tax, for
both individual and corporate investors. The Fund anticipates that a portion of
its investments will be made in such "private activity bonds," with the result
that a portion of the exempt-interest dividends paid by the Fund will be an
item of tax preference to shareholders subject to the alternative minimum tax.
In addition, certain corporations which are subject to the alternative minimum
tax may also have to include exempt-interest dividends in calculating their
alternative minimum taxable income in situations where the "adjusted current
earnings" of the corporation exceeds its alternative minimum taxable income.

   Under the Revenue Reconciliation Act of 1993, all or a portion of the 
Fund's gain from the sale or redemption of tax-exempt obligations purchased 
at a market discount after April 30, 1993 will be treated as ordinary income 
rather than capital gain. This rule may increase the amount of ordinary 
income dividends received by shareholders. 

   Within sixty days after the end of its fiscal year, the Fund will mail to 
its shareholders a statement indicating the percentage of the dividend 
distributions for such fiscal year which constitutes exempt-interest 
dividends and the percentage, if any, that is taxable, and the percentage, if 
any, of the exempt-interest dividends which constitutes an item of tax 
preference. 

   Shareholders will normally be subject to federal income tax on dividends 
paid from interest income derived from taxable securities and on 
distributions of net short-term capital gains, if any. Distributions of 
long-term capital gains, if any, are taxable as long-term capital gains, 
regardless of how long the shareholder has held the Fund shares and 
regardless of whether the distribution is received in additional shares or in 
cash. To avoid being subject to a 31% federal backup withholding tax on 
taxable dividends, capital gains distributions and proceeds of redemptions or 
repurchases, shareholders' taxpayer identification numbers must be furnished 
and certified as to accuracy. 

                                      18
<PAGE>

   Any loss on the sale or exchange of shares of the Fund which are held for 
six months or less is disallowed to the extent of the amount of any 
exempt-interest dividend paid with respect to such shares. Treasury 
Regulations may provide for a reduction in such required holding periods. If 
a shareholder receives a distribution that is taxed as a long-term capital 
gain on shares held for six months or less and sells those shares at a loss, 
the loss will be treated as a long-term capital loss. 

   Interest on indebtedness incurred by shareholders to purchase or carry 
shares of an investment company paying exempt-interest dividends, such as the 
Fund, will not be deductible by the investor for federal income tax purposes. 

   The exemption of interest income for federal income tax purposes does not 
necessarily result in exemption under the income or other tax laws of any 
state or local taxing authority. Thus, shareholders of the Fund may be 
subject to state and local taxes on exempt-interest dividends. 

   
   The Fund may at times make payments from sources other than income or net 
capital gains. Payments from such sources will, in effect, represent a return 
of a portion of each shareholder's investment. All, or a portion, of such 
payments will not be taxable to shareholders. 
    

   Shareholders should consult their tax advisers as to the applicability of 
the above to their own tax situation. 

PERFORMANCE INFORMATION 
- -------------------------------------------------------------------------------

   From time to time the Fund may quote its "yield" and/or its "total return" 
in advertisements and sales literature. Both the yield and the total return 
of the Fund are based on historical earnings and are not intended to indicate 
future performance. The yield of the Fund 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 maximum 
offering price per share at the end of the period), all in accordance with 
applicable regulatory requirements. Such amount is compounded for six months 
and then annualized for a twelve-month period to derive the Fund's yield. The 
Fund may also quote tax-equivalent yield, which is calculated by determining 
the pre-tax yield which, after being taxed at a stated rate, would be 
equivalent to the yield determined as described above. 

   The "average annual total return" of the Fund refers to a figure 
reflecting the average annualized percentage increase (or decrease) in the 
value of an initial investment of $1,000 over periods of one, five and ten 
years. 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 imposition of the front-end 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 or $100,000 in shares of the 
Fund by adding 1 to the Fund's aggregate total return to date and multiplying 
by $9,600, $48,375 or $97,250 ($10,000, $50,000 or $100,000 adjusted for 
4.00%, 3.25% and 2.75% sales charges, respectively). 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 $.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 share holder held personally liable for the obligations of the Fund. 
Thus, the risk of a shareholder incurring financial loss on account of 
shareholder liability is limited to circumstances in which the Fund itself 
would be unable to meet its obligations. Given the above limitations on 
shareholder personal liability and the nature of the Fund's assets and 
operations, the possibility of the Fund's being unable to meet its 
obligations is remote and, in the opinion of Massachusetts counsel to the 
Fund, the risk to Fund shareholders of personal liability is remote. 

   
   Code of Ethics. Directors, officers and employees of InterCapital, Dean 
Witter Services Company Inc. and the Distributor are subject to a strict Code 
of Ethics adopted by those companies. The Code of Ethics is intended to 
ensure that the interests of shareholders and other clients are placed ahead 
of any personal interest, that no undue personal benefit is obtained from a 
person's employment activities and that actual and potential conflicts of 
interest are avoided. To achieve these goals and comply with regulatory 
requirements, the Code of Ethics requires, among other things, that personal 
securities transactions by employees of the companies be subject to an 
advance clearance process to monitor that no Dean Witter Fund is engaged at 
the same time in a purchase or sale of the same security. The Code of Ethics 
bans the purchase of securities in an initial public offering, and also 
prohibits engaging in futures and options transactions and profiting on 
short-term trading (that is, a purchase within 60 days of a sale or a sale 
within 60 days of a purchase) of a security. In addition, investment 
personnel may not purchase or sell a security for their personal account 
within 30 days before or after any transaction in any Dean Witter Fund 
managed by them. Any violations of the Code of Ethics are subject to 
sanctions, including reprimand, demotion or suspension or termination of 
employment. The Code of Ethics comports with regulatory requirements and the 
recommendations in the 1994 report by the Investment Company Institute 
Advisory Group on Personal Investing.

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

THE FUND 

   The Fund was incorporated in the State of Maryland on December 31, 1979 
under the name InterCapital Tax-Exempt Securities Inc. On March 17, 1983, the 
Fund's shareholders approved a change in the Fund's name, effective March 21, 
1983, to Dean Witter Tax-Exempt Securities Inc. On April 30, 1987 the Fund 
reorganized as a Massachusetts business trust, with the name Dean Witter 
Tax-Exempt Securities Trust. 

THE INVESTMENT MANAGER 

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

nities Trust II, Municipal Income Opportunities Trust III, Prime Income Trust 
and Municipal Premium Income Trust. The foregoing investment companies, 
together with the Fund, are collectively referred to as the Dean Witter 
Funds. 

   
   In addition, Dean Witter Services Company Inc. ("DWSC"), a wholly-owned 
subsidiary of InterCapital, serves as manager for the following companies for 
which TCW Funds Management, Inc. is the investment adviser: TCW/DW Core 
Equity Trust, TCW/DW North American Government Income Trust, TCW/DW Latin 
American Growth Fund, TCW/DW Income and Growth Fund, TCW/DW Small Cap Growth 
Fund, TCW/DW Balanced Fund, TCW/DW Total Return Trust, TCW/DW Mid-Cap Equity 
Trust, TCW/DW Global Telecom Trust, TCW/DW Strategic Income Trust, TCW/DW 
Emerging Market Opportunities Trust, TCW/DW Term Trust 2000, TCW/DW Term 
Trust 2002 and TCW/DW Term Trust 2003 (the "TCW/DW Funds"). InterCapital also 
serves as (i) sub-adviser to Templeton Global Opportunities Trust, an 
open-end investment company; (ii) administrator of The Black Rock Strategic 
Term Trust Inc., a closed-end investment company; and (iii) sub-administrator 
of MassMutual Participation Investors and Templeton Global Governments Income 
Trust, closed-end investment companies. 
    

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

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

   Effective December 31, 1993, pursuant to a Services Agreement between 
InterCapital and DWSC, DWSC began to provide the administrative services to 
the Fund which were previously performed directly by InterCapital. On April 
17, 1995, DWSC was reorganized in the State of Delaware, necessitating the 
entry into a new Services Agreement by InterCapital and DWSC on that date. 
The foregoing internal reorganizations did not result in any change in the 
nature or scope of the administrative services being provided to the Fund or 
any of the fees being paid by the Fund for the overall services being 
performed under the terms of the existing Agreement. 

   Expenses not expressly assumed by the Investment Manager under the 
Agreement or by the Distributor of the Fund's shares, Dean Witter 
Distributors Inc. ("Distributors" or the "Distributor") (see "Purchase of 
Fund Shares"), will be paid by the Fund. The expenses borne by the Fund 
include, but are not limited to: charges and expenses of any registrar, 
custodian, stock transfer and dividend disbursing agent; brokerage 
commissions; taxes; engraving and printing 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 Funds or of the Investment Manager (not 
including compensation or expenses of attorneys who are employees of the 
Investment Manager) and independent accountants; 

                                       4
<PAGE>

   
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 net assets of the Fund 
determined as of the close of each business day: 0.50% of the portion of the 
daily net assets not exceeding $500 million; 0.425% of the portion of the 
daily net assets exceeding $500 million but not exceeding $750 million; 
0.375% of the portion of the daily net assets exceeding $750 million but not 
exceeding $1 billion; 0.35% of the portion of the daily net assets exceeding 
$1 billion but not exceeding $1.25 billion; and 0.325% of the portion of 
daily net assets exceeding $1.25 billion. For the fiscal years ended December 
31, 1994, 1995 and 1996, the Fund accrued to the Investment Manager total 
compensation of $6,003,589, $5,608,466 and $5,320,578, respectively. 
    

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

   The Agreement was initially approved by the Trustees on October 30, 1992 
and by the shareholders on January 12, 1993. The Agreement is substantially 
identical to a prior investment management agreement which was initially 
approved by the Fund's Trustees on April 15, 1987 and subsequently by the 
Fund's shareholders on April 21, 1987. The Agreement took effect on June 30, 
1993, upon the spin-off by Sears, Roebuck and Co. of its remaining shares of 
DWDC. The Agreement may be terminated at any time, without penalty, on thirty 
days notice, by the Board of Trustees of the Fund, by the holders of a 
majority, as defined in the Investment Company Act of 1940, as amended (the 
"Act"), of the outstanding shares of the Fund, or by the Investment Manager. 
The Agreement will automatically terminate in the event of its assignment (as 
defined in the Act). 

   
   Under its terms, the Agreement had an initial term ending April 30, 1994, 
and provides that it will continue in effect from year to year thereafter, 
provided continuance of the Agreement is approved at least annually by the 
vote of the holders of a majority (as defined in the Act) of the outstanding 
shares of the Fund, or by the Board of Trustees of the Fund; provided that in 
either event such continuance is approved annually by the vote of a majority 
of the Independent Trustees, which vote must be cast in person at a meeting 
called for the purpose of voting on such approval. At their meeting held on 
April 17, 1996, the Fund's Board of Trustees, including a majority of the 
Independent Trustees, approved continuation of the Agreement until April 30, 
1997. 
    

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

Assistant Secretaries of the Fund. 

THE BOARD OF TRUSTEES, THE INDEPENDENT TRUSTEES, AND THE COMMITTEES 

   The Board of Trustees consists of eight (8) trustees. These same 
individuals also serve as directors or trustees for all of the Dean Witter 
Funds, and are referred to in this section as Trustees. As of the date of 
this Statement of Additional Information, there are a total of 84 Dean Witter 
Funds, comprised of 126 portfolios. As of February 28, 1997, the Dean Witter 
Funds had total net assets of approximately $83.6 billion and more than five 
million shareholders. 

   Six Trustees (75% of the total number) have no affiliation or business 
connection with InterCapital or any of its affiliated persons and do not own 
any stock or other securities issued by InterCapital's parent company, DWDC. 
These are the "disinterested" or "independent" Trustees. The other two 
Trustees (the "management Trustees") are affiliated with InterCapital. Four 
of the six independent Trustees are also Independent Trustees of the TCW/DW 
Funds. 

   Law and regulation establish both general guidelines and specific duties 
for the Independent Trustees. The Dean Witter Funds seek as Independent 
Trustees individuals of distinction and experience in business and finance, 
government service or academia; these are people whose advice and counsel are 
in demand by others and for whom there is often competition. To accept a 
position on the Funds' Boards, such individuals may reject other attractive 
assignments because the Funds make substantial demands on their time. Indeed, 
by serving on the Funds' Boards, certain Trustees who would otherwise be 
qualified and in demand to serve on bank boards would be prohibited by law 
from doing so. 

   All of the Independent Trustees serve as members of the Audit Committee 
and the Committee of the Independent Trustees. Three of them also serve as 
members of the Derivatives Committee. During the calendar year ended December 
31, 1996, the three Committees held a combined total of sixteen meetings. The 
Committees hold some meetings at InterCapital's offices and some outside 
InterCapital. Management Trustees or officers do not attend these meetings 
unless they are invited for purposes of furnishing information or making a 
report. 

   The Committee of the Independent Trustees is charged with recommending to 
the full Board approval of management, advisory and administration contracts, 
Rule 12b-1 plans and distribution and underwriting agreements; continually 
reviewing Fund performance; checking on the pricing of portfolio securities, 
brokerage commissions, transfer agent costs and performance, and trading 
among Funds in the same complex; and approving fidelity bond and related 
insurance coverage and allocations, as well as other matters that arise from 
time to time. The Independent Trustees are required to select and nominate 
individuals to fill any Independent Trustee vacancy on the Board of any Fund 
that has a Rule 12b-1 plan of distribution. Most of the Dean Witter Funds 
have such a plan. 
    

                                       8
<PAGE>

   
   The Audit Committee is charged with recommending to the full Board the 
engagement or discharge of the Fund's independent accountants; directing 
investigations into matters within the scope of the independent accountants' 
duties, including the power to retain outside specialists; reviewing with the 
independent accountants the audit plan and results of the auditing 
engagement; approving professional services provided by the independent 
accountants and other accounting firms prior to the performance of such 
services; reviewing the independence of the independent accountants; 
considering the range of audit and non-audit fees; reviewing the adequacy of 
the Fund's system of internal controls; and preparing and submitting 
Committee meeting minutes to the full Board. 

   Finally, the Board of each Fund has formed a Derivatives Committee to 
establish parameters for and oversee the activities of the Fund with respect 
to derivative investments, if any, made by the Fund. 

DUTIES OF CHAIRMAN OF COMMITTEE OF THE INDEPENDENT TRUSTEES AND AUDIT 
COMMITTEE 

   The Chairman of the Committee of the Independent Trustees and the Audit 
Committee maintains an office at the Funds' headquarters in New York. He is 
responsible for keeping abreast of regulatory and industry developments and 
the Funds' operations and management. He screens and/or prepares written 
materials and identifies critical issues for the Independent Trustees to 
consider, develops agendas for Committee meetings, determines the type and 
amount of information that the Committees will need to form a judgment on 
various issues, and arranges to have that information furnished to Committee 
members. He also arranges for the services of independent experts and 
consults with them in advance of meetings to help refine reports and to focus 
on critical issues. Members of the Committees believe that the person who 
serves as Chairman of both Committees and guides their efforts is pivotal to 
the effective functioning of the Committees. 

   The Chairman of the Committees also maintains continuous contact with the 
Funds' management, with independent counsel to the Independent Trustees and 
with the Funds' independent auditors. He arranges for a series of special 
meetings involving the annual review of investment advisory, management and 
other operating contracts of the Funds and, on behalf of the Committees, 
conducts negotiations with the Investment Manager and other service 
providers. In effect, the Chairman of the Committees serves as a combination 
of chief executive and support staff of the Independent Trustees. 

   The Chairman of the Committee of the Independent Trustees and the Audit 
Committee is not employed by any other organization and devotes his time 
primarily to the services he performs as Committee Chairman and Independent 
Trustee of the Dean Witter Funds and as an Independent Trustee and, since 
July 1, 1996, as Chairman of the Committee of the Independent Trustees and 
the Audit Committee of the TCW/DW Funds. The current Committee Chairman has 
had more than 35 years experience as a senior executive in the investment 
company industry. 

ADVANTAGES OF HAVING SAME INDIVIDUALS AS INDEPENDENT TRUSTEES FOR ALL DEAN 
WITTER FUNDS 

   The Independent Trustees and the Funds' management believe that having the 
same Independent Trustees for each of the Dean Witter Funds avoids the 
duplication of effort that would arise from having different groups of 
individuals serving as Independent Trustees for each of the Funds or even of 
sub-groups of Funds. They believe that having the same individuals serve as 
Independent Trustees of all the Funds tends to increase their knowledge and 
expertise regarding matters which affect the Fund complex generally and 
enhances their ability to negotiate on behalf of each Fund with the Fund's 
service providers. This arrangement also precludes the possibility of 
separate groups of Independent Trustees arriving at conflicting decisions 
regarding operations and management of the Funds and avoids the cost and 
confusion that would likely ensue. Finally, having the same Independent 
Trustees serve on all Fund Boards enhances the ability of each Fund to 
obtain, at modest cost to each separate Fund, the services of Independent 
Trustees, and a Chairman of their Committees, of the caliber, experience and 
business acumen of the individuals who serve as Independent Trustees of the 
Dean Witter Funds. 

COMPENSATION OF INDEPENDENT TRUSTEES 

   The Fund pays each Independent Trustee an annual fee of $1,000 plus a per 
meeting fee of $50 for meetings of the Board of Trustees or committees of the 
Board of Trustees attended by the Trustee (the 
    

                                       9
<PAGE>

   
Fund pays the Chairman of the Audit Committee an annual fee of $750 and pays 
the Chairman of the Committee of the Independent Trustees an additional 
annual fee of $1,200). The Fund also reimburses such Trustees for travel and 
other out-of-pocket expenses incurred by them in connection with attending 
such meetings. Trustees and officers of the Fund who are or have been 
employed by the Investment Manager or an affiliated company receive no 
compensation or expense reimbursement from the Fund.

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

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

Board.(1) "Eligible Compensation" is one-fifth of the total compensation 
earned by such Eligible Trustee for service to the Adopting Fund in the five 
year period prior to the date of the Eligible Trustee's retirement. Benefits 
under the retirement program are not secured or funded by the Adopting Funds. 

   The following table illustrates the retirement benefits accrued to the 
Fund's Independent Trustees by the Fund for the fiscal year ended December 
31, 1996 and by the 57 Dean Witter Funds (including the Fund) for the year 
ended December 31, 1996, and the estimated retirement benefits for the Fund's 
Independent Trustees, to commence upon their retirement, from the Fund as of 
December 31, 1996 and from the 57 Dean Witter Funds as of December 31, 1996.

       method, through the remainder of the later of the lives of such 
       Eligible Trustee and spouse, will be the actuarial equivalent of the 
       Regular Benefit. In addition, the Eligible Trustee may elect that the 
       surviving spouse's periodic payment of benefits will be equal to either 
       50% or 100% of the previous periodic amount, an election that, 
       respectively, increases or decreases the previous periodic amount so 
       that the resulting payments will be the actuarial equivalent of the 
       Regular Benefit.

       Trustee until June 1, 1998. 

   As of the date of this Statement of Additional Information, the aggregate 
number of shares of beneficial interest of the Fund owned by the Fund's 
officers and Trustees as a group was less than 1 percent of the Fund's shares 
of beneficial interest outstanding. 
    

INVESTMENT PRACTICES AND POLICIES 
- -------------------------------------------------------------------------------

PORTFOLIO SECURITIES 

   The payment of principal and interest by issuers of certain Municipal 
Bonds and Notes ("Municipal Obligations") purchased by the Fund may be 
guaranteed by letters of credit or other credit facilities offered by banks 
or other financial institutions. Such guarantees will be considered in 
determining whether a Municipal Obligation meets the Fund's investment 
quality requirements. In addition, some issues may contain provisions which 
permit the Fund to demand from the issuer repayment of principal at some 
specified period(s) prior to maturity. 

   Municipal Bonds. Municipal Bonds, as referred to in the Prospectus, are 
debt obligations of a state, its cities, municipalities and municipal 
agencies (all of which are generally referred to as "municipalities") which 
generally have a maturity at the time of issuance of one year or more, and 
the interest from which is, in the opinion of bond counsel, exempt from 
federal income tax. They are issued to raise funds for various public 
purposes, such as construction of a wide range of public facilities, to 
refund outstanding obligations and to obtain funds for general operating 
expenses or to loan to other public institutions and facilities. In addition, 
certain types of industrial development bonds and pollution control bonds are 
issued by or on behalf of public authorities to provide funding for various 
privately operated facilities. 

                                       11
<PAGE>

   Municipal Notes. Municipal Notes are short-term obligations of 
municipalities, generally with a maturity at the time of issuance ranging 
from six months to three years, the interest from which is, in the opinion of 
bond counsel, exempt from federal income tax. The principal types of 
Municipal Notes include tax anticipation notes, bond anticipation notes, 
revenue anticipation notes and project notes, although there are other types 
of Municipal Notes in which the Fund may invest. Notes sold in anticipation 
of collection of taxes, a bond sale or receipt of other revenues are usually 
general obligations of the issuing municipality or agency. Project Notes are 
issued by local agencies and are guaranteed by the United States Department 
of Housing and Urban Development. Such notes are secured by the full faith 
and credit of the United States Government. Project Notes are not currently 
being issued. 

   Municipal Commercial Paper. Municipal Commercial Paper refers to 
short-term obligations of municipalities the interest from which is, in the 
opinion of bond counsel, exempt from federal income tax, and which may be 
issued at a discount and is sometimes referred to as Short-Term Discount 
Notes. Municipal Commercial Paper is likely to be used to meet seasonal 
working capital needs of a municipality or interim construction financing and 
to be paid from general revenues of the municipality or refinanced with 
long-term debt. In most cases, Municipal Commercial Paper is backed by 
letters of credit, lending agreements, note repurchase agreements or other 
credit facility agreements offered by banks or other institutions. 

   Obligations of issuers of Municipal Bonds, Municipal Notes and Municipal 
Commercial Paper are subject to provisions of bankruptcy, insolvency and 
other laws affecting the rights and remedies of creditors, such as the 
Federal Bankruptcy Act, and laws, if any, which may be enacted by Congress or 
any state extending the time for payment of principal or interest, or both, 
or imposing other constraints upon enforcement of such obligations or upon 
municipalities to levy taxes. There is also the possibility that, as a result 
of litigation or other conditions, the power or ability of any one or more 
issuers to pay, when due, principal of and interest on its, or their, 
Municipal Bonds, Municipal Notes and Municipal Commercial Paper may be 
materially affected. 

   Special Investment Considerations. The percentage and rating policies in 
the Prospectus apply at the time of acquisition of a security based upon the 
last previous determination of the Fund's net asset value; any subsequent 
change in any ratings by a rating service or change in percentages resulting 
from market fluctuations or other changes in the amount of total assets will 
not require elimination of any security from the Fund's portfolio until such 
time as the Investment Manager determines that it is practicable to sell the 
security without undue market or tax consequences to the Fund. Therefore, the 
Fund may hold securities which have been downgraded to ratings of Ba or BB or 
lower by Moody's or S&P. Such securities are considered to be speculative 
investments. 

   Furthermore, the Fund does not have any minimum quality rating standard 
for its downgraded or lower-rated 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 CI by 
S&P. Bonds rated Caa or Ca by Moody's may already be in default on payment of 
interest or principal, while bonds rated C by Moody's, their lowest bond 
rating, can be regarded as having extremely poor prospects of ever attaining 
any real investment standing. Bonds rated CI by S&P, their lowest bond 
rating, are no longer making interest payments. 

   Because of the special nature of securities which are rated below 
investment grade by national credit rating agencies ("lower-rated 
securities"), the Investment Manager must take 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 
has paralleled a long economic expansion and it has not weathered a recession 
in its present size and form. Therefore, an economic downturn or increase in 
interest rates is likely to have a negative effect on this market and on the 
value of the lower rated securities held by the Fund, as well as on the 
ability of the securities' issuers to repay principal and interest on their 
borrowings. 

   The prices of lower rated securities have been found to be less sensitive 
to changes in prevailing interest rates than higher rated investments, but 
are likely to be more sensitive to adverse economic changes or individual 
corporate developments. During an economic downturn or substantial period of 
rising interest rates, highly leveraged issuers may experience financial 
stress which would adversely 

                                       12
<PAGE>

affect their ability to service their principal and interest payment 
obligations, to meet their projected business goals or to obtain additional 
financing. If the issuer of a fixed-income security owned by the Fund 
defaults, the Fund may incur additional expenses to seek recovery. In 
addition, periods of economic uncertainty and change can be expected to 
result in an increased volatility of market prices of lower rated securities 
and a concomitant volatility in the net asset value of a share of the Fund. 
Moreover, the market prices of certain of the Fund's portfolio securities 
which are structured as zero coupon securities are affected to a greater 
extent by interest rate changes and thereby tend to be more volatile than 
securities which pay interest periodically and in cash (see "Dividends, 
Distributions and Taxes" for a discussion of the tax ramifications of 
investments in such securities). 

   The secondary market for lower rated securities may be less liquid than 
the markets for higher quality securities and, as such, may have an adverse 
effect on the market prices of certain securities. The limited liquidity of 
the market may also adversely affect the ability of the Fund's Trustees to 
arrive at a fair value for certain lower rated securities at certain times 
and should make it difficult for the Fund to sell certain securities. In 
addition, new laws and potential new laws 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. 

PORTFOLIO CHARACTERISTICS 

   Variable Rate Obligations. As stated in the Prospectus, the Fund may 
invest in obligations of the type called "variable rate obligations". 

   The interest rate payable on a variable rate obligation is adjusted either 
at predesignated periodic intervals or whenever there is a change in the 
market rate of interest on which the interest rate payable is based. Other 
features may include the right whereby the Fund may demand prepayment of the 
principal amount of the obligation prior to its stated maturity (a "demand 
feature") and the right of the issuer to prepay the principal amount prior to 
maturity. The principal benefit of a variable rate obligation is that the 
interest rate adjustment minimizes changes in the market value of the 
obligation. The principal benefit to the Fund of purchasing obligations with 
a demand feature is that liquidity, and the ability of the Fund to obtain 
repayment of the full principal amount of the obligation prior to maturity, 
is enhanced. 

   When-Issued and Delayed Delivery Securities. As stated in the Prospectus, 
the Fund may purchase tax-exempt securities on a when-issued or delayed 
delivery basis. When such transactions are negotiated, the price is fixed at 
the time of 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 or delayed delivery basis with the intention of 
acquiring the securities, the Fund may sell the securities before the 
settlement date, if it is deemed advisable. The securities so purchased or 
sold are subject to market fluctuation and no interest accrues to the 
purchaser during this period. At the time the Fund makes the commitment to 
purchase a Municipal Obligation on a when-issued or delayed delivery basis, 
it will record the transaction and thereafter reflect the value, each day, of 
the Municipal Obligation in determining its net asset value. The Fund will 
also establish a segregated account with its custodian bank in which it will 
maintain cash, cash equivalents or other high quality Municipal Obligations 
equal in value to commitments for such when-issued or delayed delivery 
securities. The Fund does not believe that its net asset value or income will 
be adversely affected by its purchase of Municipal Obligations on a 
when-issued or delayed delivery basis. The Fund may sell securities on a 
when-issued or delayed delivery basis provided that the Fund owns the 
security at the time of the sale. 

   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 

                                       13
<PAGE>

   
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. In addition, the value of 
the collateral underlying the repurchase agreement will always be a 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. 
However, the Fund did not enter into any repurchase agreements during its 
fiscal year ended December 31, 1996 and it has no intention of entering into 
any such agreements in the foreseeable future. 
    

FUTURES CONTRACTS AND OPTIONS ON FUTURES 

   As discussed in the Prospectus, the Fund may invest in financial futures 
contracts ("futures contracts") and related options thereon. These futures 
contracts and related options thereon will be used only as a hedge against 
anticipated interest rate changes. A futures contract sale creates an 
obligation by the Fund, as seller, to deliver the specific type of instrument 
called for in the contract at a specified future time for a specified price. 
A futures contract purchase would create an obligation by the Fund, as 
purchaser, to take delivery of the specific type of financial instrument at a 
specified future time at a specified price. The specific securities delivered 
or taken, respectively, at settlement date, would not be determined until on 
or near that date. The determination would be in accordance with the rules of 
the exchange on which the futures contract sale or purchase was effected. 

   Although the terms of futures contracts specify actual delivery or receipt 
of securities, in most instances the contracts are closed out before the 
settlement date without the making or taking of delivery of the securities. 
Closing out of a futures contract is usually effected by entering into an 
offsetting transaction. An offsetting transaction for a futures contract sale 
is effected by the Fund entering into a futures contract purchase for the 
same aggregate amount of the specific type of financial instrument at the 
same delivery date. If the price in the sale exceeds the price in the 
offsetting purchase, the Fund is immediately paid the difference and thus 
realizes a gain. If the offsetting purchase price exceeds the sale price, the 
Fund pays the difference and realizes a loss. Similarly, the closing out of a 
futures contract purchase is effected by the Fund entering into a futures 
contract sale. If the offsetting sale price exceeds the purchase price the 
Fund realizes a gain, and if the offsetting sale price is less than the 
purchase price the Fund realizes a loss. 

   Unlike a futures contract, which requires the parties to buy and sell a 
security on a set date, an option on a futures contract entitles its holder 
to decide on or before a future date whether to enter into such a contract (a 
long position in the case of a call option and a short position in the case 
of a put option). If the holder decides not to enter into the contract, the 
premium paid for the contract is lost. Since the value of the option is fixed 
at the point of sale, there are no daily payments of cash to reflect the 
change in the value of the underlying contract, as discussed below for 
futures contracts. The value of the option changes is reflected in the net 
asset value of the Fund. 

   The Fund is required to maintain margin deposits with brokerage firms 
through which it effects futures contracts and options thereon. The initial 
margin requirements vary according to the type of the underlying security. In 
addition, due to current industry practice, daily variations in gains and 
losses on open contracts are required to be reflected in cash in the form of 
variation margin payments. The Fund may be required to make additional margin 
payments during the term of the contract. 

                                       14
<PAGE>

   Currently, futures contracts can be purchased on debt securities such as 
U.S. Treasury Bills and Bonds, U.S. Treasury Notes with maturities between
6 1/2 and 10 years, Certificates of the Government National Mortgage
Association, Bank Certificates of Deposit and on a municipal bond index (see
below). The Fund may invest in interest rate futures contracts covering these
types of financial instruments as well as in new types of contracts that become
available in the future.

   Financial futures contracts are traded in an auction environment on the 
floors of several Exchanges--principally, the Chicago Board of Trade, the 
Chicago Mercantile Exchange and the New York Futures Exchange. Each Exchange 
guarantees performance under contract provisions through a clearing 
corporation, a nonprofit organization managed by the Exchange membership 
which is also responsible for handling daily accounting of deposits or 
withdrawals of margin. 

   A risk in employing futures contracts to protect against the price 
volatility of portfolio securities is that the prices of securities subject 
to futures contracts may correlate imperfectly with the behavior of the cash 
prices of the Fund's portfolio securities. The correlation may be distorted 
by the fact that the futures market is dominated by short-term traders 
seeking to profit from the difference between a contract or security price 
objective and their cost of borrowed funds. This would reduce the value of 
futures contracts for hedging purposes over a short time period. The 
correlation may be further distorted since the futures contracts that are 
being used to hedge are not based on municipal obligations. 

   Another risk is that the Fund's Investment Manager could be incorrect in 
its expectations as to the direction or extent of various interest rate 
movements or the time span within which the movements take place. For 
example, if the Fund sold futures contracts for the sale of securities in 
anticipation of an increase in interest rates, and then interest rates went 
down instead, causing bond prices to rise, the Fund would lose money on the 
sale. 

   Put and call options on financial futures have characteristics similar to 
Exchange traded options. For a further description of options, see below and 
the Prospectus. 

   In addition to the risks associated in investing in options on securities, 
there are particular risks associated with investing in options on futures. 
In particular, the ability to establish and close out positions on such 
options will be subject to the development and maintenance of a liquid 
secondary market. It is not certain that such a market will develop. 

   The Fund may not enter into futures contracts or related options theron 
if, immediately thereafter, the amount committed to margin plus the amount 
paid for option premiums exceeds 5% of the value of the Fund's total assets. 
In instances involving the purchase of futures contracts by the Fund, an 
amount equal to the market value of the futures contract will be deposited in 
a segregated account of cash and cash equivalents to collateralize the 
position and thereby ensure that the use of such futures is unleveraged. The 
Fund may not purchase or sell futures contracts or related options if, 
immediately thereafter, more than one-third of its net assets would be 
hedged. 

   Municipal Bond Index Futures--The Fund may utilize municipal bond index 
futures contracts and options thereon for hedging purposes. The Fund's 
strategies in employing such contracts will be similar to that discussed 
above with respect to financial futures and options thereon. A municipal bond 
index is a method of reflecting in a single number the market value of many 
different municipal bonds and is designed to be representative of the 
municipal bond market generally. The index fluctuates in response to changes 
in the market values of the bonds included within the index. Unlike futures 
contracts on particular financial instruments, futures contracts on a 
municipal bond index will be settled in cash if held until the close of 
trading in the contract. However, as in any other futures contract, a 
position in the contract may be closed out by purchase or sale of an 
offsetting contract for the same delivery month prior to expiration of the 
contract. 

   Options--The Fund may purchase or sell (write) options on debt securities 
as a means of achieving additional return or hedging the value of the Fund's 
portfolio. The Fund will only buy options listed on national securities 
exchanges. The Fund will not purchase options if, as a result, the aggregate 
cost of all outstanding options exceeds 10% of the Fund's total assets. 

                                       15
<PAGE>

   Presently there are no options on tax-exempt securities traded on national 
securities exchanges and until such time as they become available, the Fund 
will not invest in options on debt securities. 

   A call option is a contract that gives the holder of the option the right 
to buy from the writer of the call option, in return for a premium, the 
security underlying the option at a specified exercise price at any time 
during the term of the option. The writer of the call option has the 
obligation, upon exercise of the option, to deliver the underlying security 
upon payment of the exercise price during the option period. A put option is 
a contract that gives the holder of the option the right to sell to the 
writer, in return for a premium, the underlying security at a specified price 
during the term of the option. The writer of the put has the obligation to 
buy the underlying security upon exercise, at the exercise price during the 
option period. 

   
   The Fund will only write covered call or covered put options listed on 
national exchanges. The Fund may not write covered options in an amount 
exceeding 20% of the value of its total assets. A call option is "covered" if 
the Fund owns the underlying security covered by the call or has an absolute 
and immediate right to acquire that security or futures contract without 
additional cash consideration (or for additional cash consideration held in a 
segregated account by its custodian) upon conversion or exchange of other 
securities held in its portfolio. A call option is also covered if the Fund 
holds a call on the same security or futures contract as the call written, 
where the exercise price of the call held is (i) equal to or less than the 
exercise price of the call written or (ii) greater than the exercise price of 
the call written if the difference is maintained by the Fund in cash, 
Treasury bills or other liquid portfolio securities in a segregated account 
with its custodian. A put option is "covered" if the Fund maintains cash, 
Treasury bills or other high grade short-term obligations with a value equal 
to the exercise price in a segregated account with its custodian, or else 
holds a put on the same security or futures contract as the put written where 
the exercise price of the put held is equal to or greater than the exercise 
price of the put written. 
    

   If the Fund has written an option, it may terminate its obligation by 
effecting a closing purchase transaction. This is accomplished by purchasing 
an option of the same series as the option previously written. However, once 
the Fund has been assigned an exercise notice, the Fund will be unable to 
effect a closing purchase transaction. Similarly, if the Fund is the holder 
of an option, it may liquidate its position by effecting a closing sale 
transaction. This is accomplished by selling an option of the same series as 
the option previously purchased. There can be no assurance that either a 
closing purchase or sale transaction can be effected when the Fund so 
desires. 

   The Fund will realize a profit from a closing transaction if the price of 
the transaction is less than the premium received from writing the option or 
is more than the premium paid to purchase the option; the Fund will realize a 
loss from a closing transaction if the price of the transaction is more than 
the premium received from writing the option or is less than the premium paid 
to purchase the option. Since call option prices generally reflect increases 
in the price of the underlying security, any loss resulting from the purchase 
of a call option may also be wholly or partially offset by unrealized 
appreciation of the underlying security. If a put option written by the Fund 
is exercised, the Fund may incur a loss equal to the difference between the 
exercise price of the option and the sum of the sale price of the underlying 
security plus the premiums received from the sale of the option. Other 
principal factors affecting the market value of a put or a call option 
include supply and demand, interest rates, the current market price and price 
volatility of the underlying security and the time remaining until the 
expiration date. 

   An option position may be closed out only on an exchange which provides a 
secondary market for an option of the same series. Although the Fund will 
generally purchase or write only those options for which there appears to be 
an active secondary market, there is no assurance that a liquid secondary 
market on an exchange will exist for any particular option. In such event, it 
might not be possible to effect closing transactions in particular options, 
so that the Fund would have to exercise its options in order to realize any 
profit and would incur brokerage commissions upon the exercise of call 
options and upon the subsequent disposition of underlying securities for the 
exercise of put options. If the Fund as a covered call option writer is 
unable to effect a closing purchase transaction in a secondary market, it 
will not be able to sell the underlying security until the option expires or 
it delivers the underlying security upon exercise.

PORTFOLIO MANAGEMENT 

   The Fund may engage in short-term trading consistent with its investment 
objective. Securities may be sold in anticipation of a market decline (a rise 
in interest rates) or purchased in anticipation of a market rise (a decline 
in interest rates). In addition, a security may be sold and another security 
of comparable equality purchased at approximately the same time to take 
advantage of what the Investment Manager believes to be a temporary disparity 
in the normal yield relationship between the two securities. These yield 
disparities may occur for reasons not directly related to the investment 
quality of particular issues or the general movement of interest rates, such 
as changes in the overall demand for, or supply of, various types of 
tax-exempt securities. 

   In general, purchases and sales may also be made to restructure the 
portfolio in terms of average maturity, quality, coupon yield, or 
diversification for any one or more of the following purposes: (a) to 
increase income, (b) to improve portfolio quality, (c) to minimize capital 
depreciation, (d) to realize gains or losses, or for such other reasons as 
the Investment Manager deems relevant in light of economic and market 
conditions. 

   The Fund may invest in obligations customarily sold to institutional 
investors in private transactions with the issuers thereof and up to 5% of 
its total assets in securities for which a bona fide market does not exist at 
the time of purchase. With respect to any securities as to which a bona fide 
market does not exist, the Fund may be unable to dispose of such securities 
promptly at reasonable prices. 

   The Fund does not generally intend to invest more than 25% of its total 
assets in securities of any one governmental unit or in the securities of 
governmental units located in any one state, territory or possession of the 
United States. Subject to investment restriction number 3 disclosed in the 
Prospectus under the Section "Investment Restrictions," the Fund may invest 
more than 25% of its total assets in industrial development and pollution 
control bonds (two kinds of tax-exempt Municipal Bonds). 

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

   In addition to the investment restrictions enumerated in the Prospectus, 
the investment restrictions listed below have been adopted by the Fund as 
fundamental policies, which may not be changed without the vote of a majority 
of the outstanding voting securities of the Fund, as defined in the Act. Such 
a majority is defined as the lesser of (a) 67% of the shares present at a 
meeting of shareholders, if the holders of more than 50% of the outstanding 
shares of the Fund are present or represented by proxy, or (b) more than 50% 
of the outstanding shares of the Fund. For purposes of the following 
restrictions: (a) an "issuer" of a security is the entity whose assets and 
revenues are committed to the payment of interest and principal on that 
particular security, provided that the guarantee of a security will be 
considered a separate security, and provided further that a guarantee of a 
security shall not be deemed to be a security issued by the guarantor if the 
value of all securities issued or guaranteed by the guarantor and owned by 
the Fund does not exceed 10% of the value of the total assets of the Fund; 
(b) a "taxable security" is any security the interest on which is subject to 
federal income tax; and (c) all percentage limitations apply immediately 
after a purchase or initial investment, and any subsequent change in any 
applicable percentage resulting from market fluctuations or other changes in 
the amount of total or net assets does not require elimination of any 
security from the portfolio. 

   The Fund may not: 

      1. Invest in common stock.

      2. Invest in securities of any issuer if, to the knowledge of the Fund,
   any officer or trustee/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.

      3. Purchase or sell real estate or interests therein, although it may
   purchase securities secured by real estate or interests therein.

      4. Purchase or sell commodities except that the Fund may purchase or sell
   financial futures contracts and related options thereon.

                                       17
<PAGE>

      5. Purchase oil, gas or other mineral leases, rights or royalty
   contracts, or exploration or development programs.

      6. Write, purchase or sell puts, calls, or combinations thereof, except
   for options on futures contracts or options on debt securities.

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

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

      9. Pledge its assets or assign or otherwise encumber them except to
   secure borrowing effected within the limitations set forth in Restriction 8.
   However, for the purpose of this restriction, collateral arrangements with
   respect to the writing of options and collateral arrangements with respect
   to initial margin for futures are not deemed to be pledges of assets.

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

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

      12. Make short sales of securities.

      13. Purchase securities on margin, except for such short-term loans as
   are necessary for the clearance of purchases of portfolio securities.

      14. Engage in the underwriting of securities, except insofar as the Fund
   may be deemed an underwriter under the Securities Act of 1933 in disposing
   of a portfolio security.

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

   
PORTFOLIO TRANSACTIONS AND BROKERAGE 
- -------------------------------------------------------------------------------

   Subject to the general supervision of the Board of Trustees, 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. The Fund expects that the primary market for the securities in which it 
intends to invest will generally be the over-the-counter market. Securities 
are generally traded in the over-the-counter market on an "net" basis with 
dealers acting as principal for their own account without charging a stated 
commission, although the price of the security usually includes a profit to 
the dealer. Options and futures transactions will usually be effected through 
a broker and a commission will be charged. The Fund also expects that 
securities will be purchased at times in underwritten offerings, where the 
price includes a fixed amount of compensation, generally referred to as the 
underwriter's concession or discount. On occasion, the Fund may also purchase 
certain money market instruments directly from an issuer, in which case no 
commissions or discounts are paid. During the fiscal years ended December 31, 
1994, 1995 and 1996, the Fund paid no brokerage commissions. 

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

                                       18
<PAGE>

   
In the case of certain initial and secondary public offerings, the Investment 
Manager may utilize a pro-rata allocation process based on the size of the 
Dean Witter Funds involved and the number of shares available from the public 
offering. 
    

   The policy of the Fund regarding purchases and sales of securities and 
futures contracts for its portfolio is that primary consideration will be 
given to obtaining the most favorable prices and efficient execution of 
transactions. Consistent with this policy, when securities transactions are 
effected on a stock exchange, the Fund's policy is to pay commissions which 
are considered fair and reasonable without necessarily determining that the 
lowest possible commissions are paid in all circumstances. The Fund believes 
that a requirement always to seek the lowest commission cost could impede 
effective portfolio management and preclude the Fund and the Investment 
Manager from obtaining a high quality of brokerage and research services. In 
seeking to determine the reasonableness of brokerage commissions paid in any 
transaction, the Investment Manager relies upon its experience and knowledge 
regarding commissions generally charged by various brokers and on its 
judgment in evaluating the brokerage and research services received from the 
broker effecting the transaction. Such determinations are necessarily 
subjective and imprecise, as in most cases an exact dollar value for those 
services is not ascertainable. 

   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 who 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 thus 
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. 

   Pursuant to an order of the Securities and Exchange Commission, the Fund 
may effect principal transactions in certain money market instruments with 
DWR. The Fund will limit its transactions with DWR to U.S. Government and 
Government Agency Securities, Bank Money Instruments (i.e., Certificates of 
Deposit and Bankers' Acceptances) and Commercial Paper (not including 
Tax-Exempt Municipal Paper). Such transactions will be effected with DWR only 
when the price available from DWR is better than that available from other 
dealers. 

   
   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. The Fund did not effect any 
securities transactions with or through DWR or any other selected 
broker-dealer affiliated with the Fund or its Investment Manager during its 
fiscal years ended December 31, 1994, 1995 and 1996.

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

   
   As discussed in the Prospectus, the Fund offers its shares on a continuous 
basis at an offering price equal to the net asset value per share next 
determined following receipt of an effective order, plus a sales charge based 
upon the aggregate amount of the investment (see the Prospectus--"Purchase of 
Fund Shares"). The "Statement of Assets and Liabilities" set forth in the 
Financial Statements contained within this Statement of Additional 
Information illustrates the computation of the offering price for a share of 
the Fund on December 31, 1996 and is incorporated herein by reference. 

   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 a wholly-owned subsidiary of DWDC. 
The Board of Trustees of the Fund, including a majority of the Trustees who 
are not, and were not at the time of their vote "interested persons" (as 
defined in the Act) of either party to the Distribution Agreement (the 
"Independent Trustees"), approved, at its meeting held on October 30, 1992, 
the current Distribution Agreement appointing the Distributor exclusive 
distributor of the Fund's shares and providing for the Distributor to bear 
distribution expenses not borne by the Fund. The Distribution Agreement took 
effect on June 30, 1993 upon the spin-off by Sears, Roebuck and Co. of its 
remaining shares of DWDC. By its terms, the Distribution Agreement had an 
initial term ending April 30, 1994, and provides that it will remain in 
effect from year to year thereafter if approved by the Board. At their 
meeting held on April 17, 1996, the Trustees, including a majority of the 
Independent Trustees, approved the continuation of the Distribution Agreement 
until April 30, 1997. 
    

   The Distributor has agreed to pay certain expenses of the offering of the 
Fund's shares, including the cost of printing and distributing prospectuses 
and supplements thereto used in connection with the offering and sale of the 
Fund's shares. The Fund will bear the costs of initial typesetting, printing 
and distribution of prospectuses, statements of additional information, 
proxies and annual and interim reports to shareholders. The Fund and the 
Distributor have agreed to indemnify each other against certain liabilities, 
including liabilities under the Securities Act of 1933, as amended. 

   
   The Distributor has informed the Fund that it and/or DWR received sales 
charges on sales of the Fund's shares in the approximate amounts of 
$2,276,000, $972,000 and $1,050,000, for the fiscal years ended December 31, 
1994, 1995 and 1996, respectively. 
    

REDUCED SALES CHARGES 

   Right of Accumulation. As discussed in the Prospectus, investors may 
combine the current value of shares purchased in separate transactions for 
purposes of benefitting from the reduced sales charges available for 
purchases of shares of the Fund totalling at least $25,000 in net asset 
value. For example, if any person or entity who qualifies for this privilege 
holds shares of the Fund having a current value of $5,000, and purchases 
$20,000 of additional shares of the Fund, the sales charge applicable to the 
$20,000 purchase would be 3.5% of the offering price. 

   
   For the purposes of this Right of Accumulation, the cumulative current net 
asset value of any shares of Dean Witter Liquid Asset Fund Inc., Dean Witter 
Tax-Free Daily Income Trust, Dean Witter California Tax-Free Daily Income 
Trust, Dean Witter New York Municipal Money Market Trust, Dean Witter U.S. 
Government Money Market Trust, Dean Witter Short-Term U.S. Treasury Trust, 
Dean Witter Short-Term Bond Fund, Dean Witter Limited Term Municipal Trust, 
Dean Witter Balanced Income Fund, Dean Witter Balanced Growth Fund and Dean 
Witter Intermediate Term U.S. Treasury Trust, originally purchased with the 
proceeds of shares of the Fund or Dean Witter High Yield Securities Inc. or 
with the proceeds of shares of a Dean Witter Fund sold with a contingent 
deferred sales charge ("CDSC fund") and held in an Exchange Privilege Account 
of that fund in the name of a shareholder of the Fund (see "Shareholder 
Services--Exchange Privilege") and shares of Dean Witter High Yield 
Securities Inc. or a CDSC fund held by the shareholder will be added to the 
value of shares of the Fund owned by the shareholder in determining the sales 
charge applicable to any new purchases of Fund shares. 
    

                                       20
<PAGE>

   The Distributor must be notified by the selected broker-dealer or the 
shareholder at the time a purchase order is placed that the purchase 
qualifies for the reduced charge under the Right of Accumulation. Similar 
notification must be made in writing by the selected broker-dealer or 
shareholder when such an order is placed by mail. The reduced sales charge 
will not be granted if: (a) such notification is not furnished at the time of 
the order; or (b) a review of the records of the Distributor or Dean Witter 
Trust Company (the "Transfer Agent") fails to confirm the investor's 
represented holdings. 

   Letter of Intent. As discussed in the prospectus under the caption 
"Reduced Sales Charges," reduced sales charges are available to investors who 
enter into a written Letter of Intent providing for the purchase, within a 
thirteen-month period, of shares of the Fund from the Distributor or from a 
single selected broker-dealer which has entered into a Selected Dealer 
Agreement with the Distributor. 

   A Letter of Intent permits an investor to establish a total investment 
goal to be achieved by any number of purchases over a thirteen-month period. 
Each purchase made during the period will receive the reduced sales 
commission applicable to the amount represented by the goal, as if it were a 
single purchase. A number of shares equal in value to 5% of the dollar amount 
of the Letter of Intent will be held in escrow by the Transfer Agent, in the 
name of the shareholder. The initial purchase under a Letter of Intent must 
be equal to at least 5% of the stated investment goal. 

   The Letter of Intent does not obligate the investor to purchase, nor the 
Fund to sell, the indicated amount. In the event the Letter of Intent goal is 
not achieved within the thirteen-month period, the investor is required to 
pay the difference between the sales charge otherwise applicable to the 
purchases made during this period and sales charges actually paid. Such 
payment may be made directly to the Distributor or, if not paid, the 
Distributor is authorized by the shareholder to liquidate a sufficient number 
of his or her escrowed shares to obtain such difference. 

   If the goal is exceeded and purchases pass the next sales charge level, 
the sales charge on the entire amount of the purchase that results in passing 
that level and on subsequent purchases will be subject to further reduced 
sales charges in the same manner as set forth above under Right of 
Accumulation, but there will be no retroactive reduction of sales charges on 
previous purchases. For the purpose of determining whether the investor is 
entitled to a further reduced sales charge applicable to purchases at or 
above a sales charge level which exceeds the stated goal of a Letter of 
Intent, the cumulative current net asset value of any shares owned by the 
investor in an Exchange Privilege Account with Dean Witter Liquid Asset Fund 
Inc., Dean Witter Tax-Free Daily Income Trust, Dean Witter California 
Tax-Free Daily Income Trust, Dean Witter New York Municipal Money Market 
Trust, Dean Witter U.S. Government Money Market Trust, Dean Witter Short-Term 
U.S. Treasury Trust, Dean Witter Short-Term Bond Fund, Dean Witter Limited 
Term Municipal Trust, Dean Witter Balanced Income Fund, Dean Witter Balanced 
Growth Fund and Dean Witter Intermediate Term U.S. Treasury Trust, if such 
shares were originally purchased with the proceeds of shares of the Fund, 
Dean Witter High Yield Securities Inc. or CDSC fund held by the shareholder 
will be added to the cost or net asset value of shares of the Fund owned by 
the investor. (See "Shareholder Services--Exchange Privilege.") However, 
shares of Dean Witter Liquid Asset Fund Inc., Dean Witter Tax-Free Daily 
Income Trust, Dean Witter California Tax-Free Daily Income Trust, Dean Witter 
New York Municipal Money Market Trust, Dean Witter U.S. Government Money 
Market Trust, Dean Witter Short-Term U.S. Treasury Trust, Dean Witter 
Short-Term Bond Fund or Dean Witter Limited Term Municipal Trust held in an 
Exchange Privilege Account and the purchase of shares of any other Dean 
Witter Funds will not be included in determining whether the stated goal of a 
Letter of Intent has been reached. 

   At any time while a Letter of Intent is in effect, a shareholder may, by 
written notice to the Distributor, increase the amount of the stated goal. In 
that event, only shares purchased during the previous 90-day period and still 
owned by the shareholder will be included in the new sales charge reduction. 
The 5% escrow and minimum purchase requirements will be applicable to the new 
stated goal. Investors electing to purchase shares of the Fund pursuant to a 
Letter of Intent should carefully read such Letter of Intent. 

   Acquisition of Certain Investment Companies. The public offering price of 
a share of the Fund may be reduced to the net asset value per share in 
connection with the acquisition of the assets of, or merger or consolidation 
with, a personal holding company or public or private investment company. The 
value 

                                       21
<PAGE>

of the assets or company acquired in a tax-free transaction may, in 
appropriate cases, be adjusted to reduce possible adverse tax consequences to 
the Fund which might result from an acquisition of assets having net 
unrealized appreciation which is disproportionately higher at the time of 
acquisition than the realized or unrealized appreciation of the Fund. 

DETERMINATION OF NET ASSET VALUE 

   As discussed in the Prospectus, the net asset value of a share of the Fund 
is determined once daily at 4:00 p.m., New York time (or, on days when the 
New York Stock Exchange closes prior to 4 p.m., at such earlier time), on 
each day that the New York Stock Exchange is open. The New York Stock 
Exchange currently observes the following holidays: New Year's Day; 
Presidents' Day; Good Friday; Memorial Day; Independence Day; Labor Day; 
Thanksgiving Day; and Christmas Day. 

   Portfolio securities (other than short-term debt securities and futures 
and options) are valued for the Fund by an outside independent pricing 
service approved by the Board of Trustees. The pricing service has informed 
the Fund that in valuing the Fund's portfolio securities it uses both a 
computerized grid matrix of tax-exempt securities and evaluations by its 
staff, in each case based on information concerning market transactions and 
quotations from dealers which reflect the bid side of the market each day. 
The Fund's portfolio securities are thus valued by reference to a combination 
of transactions and quotations for the same or other securities believed to 
be comparable in quality, coupon, maturity, type of issue, call provisions, 
trading characteristics and other features deemed to be relevant. The Board 
of Trustees believes that timely and reliable market quotations are generally 
not readily available to the Fund for purposes of valuing tax-exempt 
securities and that the valuations supplied by the pricing service, using the 
procedures outlined above and subject to periodic review, are more likely to 
approximate the fair value of such securities. The Investment Manager will 
periodically review and evaluate the procedures, methods and quality of 
services provided by the pricing service then being used by the Fund and may, 
from time to time, recommend to the Board of Trustees the use of other 
pricing services or discontinuance of the use of any pricing service in whole 
or part. The Board may determine to approve such recommendation or take other 
provisions for pricing of the Fund's portfolio securities. 

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, maintained by 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 
DWR or other selected broker-dealer. 

   
   Targeted Dividends. (Service Mark)  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 Tax-Exempt 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 (without sales charge) 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. (Service Mark)  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 

                                       22
<PAGE>

at the net asset value calculated the same business day the transfer of funds 
is effected. For further information or to subscribe to EasyInvest, 
shareholders should contact their DWR or other selected broker-dealer account 
executive or the Transfer Agent. 

   Investment of Dividends or Distributions Received in Cash. Any shareholder 
who receives a cash payment representing a dividend or capital gains 
distribution may invest such dividend or distribution at the net asset value 
(without sales charge) next determined by returning the check or the proceeds 
to the Transfer Agent within 30 days after the payment date. If the 
shareholder returns the proceeds of a dividend or distribution, such funds 
must be accompanied by a signed statement indicating that the proceeds 
constitute a dividend or distribution to be invested. Such investment will be 
made at the net asset value per share (without sales charge) next determined 
after receipt of the proceeds by the Transfer Agent. 

   Direct Investments through Transfer Agent. A shareholder may make 
additional investments in Fund shares at any time through the Shareholder 
Investment Account by sending a check in any amount, not less than $100, 
payable to Dean Witter Tax-Exempt Securities Trust, directly to the Fund's 
Transfer Agent. After deduction of the applicable sales charge, the balance 
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. 

   Systematic Withdrawal Plan. As discussed in the Prospectus, a withdrawal 
plan is available for shareholders who own or purchase shares of the Fund 
having a minimum value of $10,000 based upon their current net asset value. 
The 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. 

   Dividends and capital gains distributions on shares held under the 
Systematic Withdrawal Plan will be invested in additional full and fractional 
shares at net asset value (without a sales charge). Shares will be credited 
to an open account for the investor by the Transfer Agent; no share 
certificates will be issued. A shareholder is entitled to a share certificate 
upon written request to the Transfer Agent, although in that event the 
shareholder's Systematic Withdrawal Plan will be terminated. 

   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 on the tenth or 
twenty-fifth day (or next following business day) of the relevant month or 
quarter and normally a check for the proceeds will be mailed by the Transfer 
Agent within five days after the date of redemption. The Systematic 
Withdrawal Plan may be terminated at any time by the Transfer Agent. 

   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 and the address to which checks are mailed 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 Systematic 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 Shareholder Investment 
Account. The shareholder may also redeem all or part of the shares held in 
the Systematic Withdrawal Plan Account (see "Redemptions and Repurchases") at 
any time. 

EXCHANGE PRIVILEGE 

   As discussed in the Prospectus, the Fund makes available to its 
shareholders an Exchange Privilege whereby shareholders of the Fund may 
exchange their shares for shares of other Dean Witter Funds sold with a 
front-end (at the time of purchase) sales charge ("FESC funds"), for shares 
of Dean 

                                       23
<PAGE>

Witter Funds sold with a contingent deferred sales charge ("CDSC funds"), for 
shares of five Dean Witter Funds which are money market funds, and for shares 
of Dean Witter Limited Term Municipal Trust, Dean Witter Short-Term Bond 
Fund, Dean Witter Short-Term U.S. Treasury Trust, Dean Witter Balanced Growth 
Fund, Dean Witter Balanced Income Fund and Dean Witter Intermediate Term U.S. 
Treasury Trust (the foregoing eleven non-FESC or CDSC funds are hereinafter 
referred to for purposes of this section as the "Exchange Funds"). Exchanges 
may be made after the shares of the CDSC fund or FESC fund acquired by 
purchase (not by exchange or dividend reinvestment) have been held for thirty 
days. There is no holding period for exchanges of shares acquired by exchange 
or dividend reinvestment. However, shares of CDSC funds, including shares 
acquired in exchange for shares of FESC funds, may not be exchanged for 
shares of FESC funds. Thus, shareholders who exchange their Fund shares for 
shares of CDSC funds may subsequently exchange those shares for shares of 
other CDSC funds or for shares of Exchange Funds, but may not reacquire FESC 
fund shares by exchange. 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). 

   With respect to the repurchase of shares of the Fund, the application of 
proceeds to the purchase of new shares in the Fund or any other of the funds 
and the general administration of the Exchange Privilege, the Transfer Agent 
acts as agent for the Distributor and for the shareholder's selected 
broker-dealer, if any, in the performance of such functions. 

   With respect to exchanges, redemptions or repurchases, the Transfer Agent 
shall be liable for its own negligence and not for the default or negligence 
of its correspondents or for losses in transit. The Fund shall not be liable 
for any default or negligence of the Transfer Agent, the Distributor or any 
selected broker-dealer. 

   The Distributor and any selected broker-dealer have authorized and 
appointed the Transfer Agent to act as their agent in connection with the 
application of proceeds of any redemption of Fund shares to the purchase of 
shares of any other fund and the general administration of the Exchange 
Privilege. No commission or discounts will be paid to the Distributor or any 
selected broker-dealer for any transactions pursuant to this Exchange 
Privilege. 

   
   Exchanges are subject to the minimum investment requirement and any other 
conditions imposed by each fund. (The minimum initial investment is $5,000 
for Dean Witter Liquid Asset Fund Inc., Dean Witter Tax-Free Daily Income 
Trust, Dean Witter New York Municipal Money Market Trust and Dean Witter 
California Tax-Free Daily Income Trust, although those funds may, at their 
discretion, accept initial investments of as low as $1,000. The minimum 
initial investment for Dean Witter Short-Term U.S. Treasury Trust is $10,000, 
although that fund may, at its discretion, accept initial investments of as 
low as $5,000. The minimum initial investment is $5,000 for Dean Witter 
Special Value Fund. The minimum initial investment for all other Dean Witter 
Funds for which the Exchange Privilege is available is $1,000.) Upon exchange 
into an Exchange Fund, the shares of that fund will be held in a special 
Exchange Privilege Account separately from accounts of those shareholders who 
haved acquired their shares directly from that fund. As a result, certain 
services normally available to shareholders of Exchange 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 

                                       24
<PAGE>

   
months prior written notice of termination will be given to the shareholders 
who hold shares of Exchange Funds, pursuant to the Exchange Privilege and 
provided further that the Exchange Privilege may be terminated or materially 
revised without notice at times (a) when the New York Stock Exchange is 
closed for other than customary weekends and holidays, (b) when trading on 
that Exchange is restricted, (c) when an emergency exists as a result of 
which disposal by the Fund of securities owned by it is not reasonably 
practicable or it is not reasonably practicable for the Fund fairly to 
determine the value of its net assets, (d) during any other period when the 
Securities and Exchange Commission by order so permits (provided that 
applicable rules and regulations of the Securities and Exchange Commission 
shall govern as to whether the conditions prescribed in (b) or (c) exist), or 
(e) if the Fund would be unable to invest amounts effectively in accordance 
with its investment objective(s), policies and restrictions. 

   For further information regarding the Exchange Privilege, shareholders 
should contact 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. 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 supplement to the prospectus or a 
new 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 regulations of the 
Securities and Exchange Commission shall govern as to whether the conditions 
prescribed in (b) or (c) exist. 

                                       25
<PAGE>

   If the shares to be redeemed have recently been purchased by check 
(including a certified or bank cashier's check), payment of redemption 
proceeds may be delayed for the minimum time needed to verify that the check 
used for investment has been honored (not more than fifteen days from the 
time of receipt of the check by the Transfer Agent). Shareholders maintaining 
margin accounts with DWR or another selected broker-dealer are referred to 
their account executive regarding restrictions on redemption of shares of the 
Fund pledged in the margin account. 

   Reinstatement Privilege. As described 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 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 
(without sales charge) next determined after a 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 the redemption or repurchase, 
except that if the redemption or repurchase resulted in a loss and 
reinstatement is made in shares of the Fund, some or all of the loss, 
depending on the amount reinstated, will not be allowed as a deduction for 
federal income tax purposes but will be applied to adjust the cost basis of 
the shares acquired upon reinstatement. 

   Involuntary Redemption. As described in the Prospectus, due to the 
relatively high cost of handling small investments, the Fund reserves the 
right to redeem, at net asset value, the shares of any shareholder whose 
shares have a value of less than $100, or such lesser amount as may be fixed 
by the Board of Trustees. However, before the Fund redeems such shares and 
sends the proceeds to the shareholder, it will notify the shareholder that 
the value of 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. 

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

   Each shareholder will receive at least a quarterly summary of his or her 
account, including information as to reinvested dividends and capital gains 
distributions. Share certificates for dividends or distributions will not be 
issued unless a shareholder requests in writing that a certificate be issued 
for a specific number of shares. 

   In computing net investment income, the Fund will amortize any premiums 
and original issue discounts on securities owned, if applicable. Capital 
gains or losses realized upon sale or maturity of such securities will be 
based on their amortized cost. 

   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. 

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

   With respect to the Fund's investments in zero coupon bonds, the Fund 
accrues income prior to any actual cash payments by their issuers. In order 
to continue to comply with Subchapter M of the Internal Revenue Code and 
remain able to forego payment of federal income tax on its income and capital 
gains, the Fund must distribute all of its net investment income, including 
income accrued from zero coupon bonds. As such, the Fund may be required to 
dispose of some of its portfolio securities under disadvantageous 
circumstances to generate the cash required for distribution. 

   As discussed in the Prospectus, the Fund intends to qualify to pay 
"exempt-interest dividends" to its shareholders by maintaining, as of the 
close of each of its taxable years, at least 50% of the value of its assets 
in tax-exempt securities. An exempt-interest dividend is that part of the 
dividend distributions 

                                       26
<PAGE>

made by the Fund which consists of interest received by the Fund on 
tax-exempt securities upon which the shareholder incurs no federal income 
taxes. Exempt-interest dividends are included however, in determining what 
portion, if any, of a person's Social Security benefits are subject to 
federal income tax. 

   As also discussed in the Prospectus, the Fund intends to invest a portion 
of its assets in certain "private activity bonds" issued after August 7, 
1986. As a result, a portion of the exempt-interest dividends paid by the 
Fund will be an item of tax preference to shareholders subject to the 
alternative minimum tax. Certain corporations which are subject to the 
alternative minimum tax may also have to include exempt-interest dividends in 
calculating their alternative minimum taxable income in situations where the 
"adjusted current earnings" of the corporation exceeds its alternative 
minimum taxable income. 

   Within sixty days after the end of its fiscal year, the Fund will mail to 
shareholders a statement indicating the percentage of the dividend 
distributions for each fiscal year which constitutes exempt-interest 
dividends, the percentage, if any, that is taxable, and the percentage, if 
any, of the exempt-interest dividends which constitutes an item of tax 
preference, and to what extent the taxable portion is long-term capital gain, 
short-term capital gain or ordinary income. This percentage should be applied 
uniformly to all monthly distributions made during the fiscal year to 
determine the proportion of dividends that is tax-exempt. The percentage may 
differ from the percentage of tax-exempt dividend distributions for any 
particular month. 

   Shareholders will be subject to federal income tax on dividends paid from 
interest income derived from taxable securities and on distributions of net 
short-term capital gains. Such dividends and distributions are taxable to the 
shareholder as ordinary dividend income regardless of whether the shareholder 
receives such distributions in additional shares or in cash. Distributions of 
long-term capital gains, if any, are taxable as long-term capital gains, 
regardless of how long the shareholder has held the Fund shares and 
regardless of whether the distribution is received in additional shares or in 
cash. Since the Fund's income is expected to be derived entirely from 
interest rather than dividends, it is anticipated that no portion of such 
dividend distributions will be eligible for the federal dividends received 
deduction available to corporations. 

   Interest on indebtedness incurred by shareholders to purchase or carry 
shares of the Fund is not deductible. Furthermore, entities or persons who 
are "substantial users" (or related persons) of facilities financed by 
industrial development bonds should consult their tax advisers before 
purchasing shares of the Fund. "Substantial user" is defined generally by 
Income Tax Regulation 1.103-11(b) as including a "non-exempt person" who 
regularly uses in a trade or business a part of a facility financed from the 
proceeds of industrial development bonds. 

   From time to time, proposals have been introduced before Congress for the 
purpose of restricting or eliminating the federal income tax exemption for 
interest on municipal securities. Similar proposals may be introduced in the 
future. If such a proposal were enacted, the availability of municipal 
securities for investment by the Fund could be affected. In that event, the 
Fund would re-evaluate its investment objective and policies. 

   Any dividends or capital gains distributions received by a shareholder 
from any investment company will have the effect of reducing the net asset 
value of the shareholder's shares in that fund by the exact amount of the 
dividend or capital gains distribution. Furthermore, capital gains 
distributions are, and some portion of the dividends may be, subject to 
income tax. If the net asset value of the shares should be reduced below a 
shareholder's cost as a result of the payment of taxable dividends or the 
distribution of capital gains, such payment or distribution would be in part 
a return of capital but nonetheless taxable to the shareholder. Therefore, an 
investor should consider the tax implications of purchasing Fund shares 
immediately prior to a distribution record date. 

   Shareholders should consult their tax advisers regarding specific 
questions as to state or local taxes. 

                                       27

PERFORMANCE INFORMATION 
- -------------------------------------------------------------------------------

   As discussed in the Prospectus, from time to time the Fund may quote its 
"yield" and/or its "total return" in advertisements and sales literature. 
Yield is calculated for any 30-day period as follows: the amount of interest 
income for each security in the Fund's portfolio is determined as described 
below; 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 maximum offering price per share on the last day of the period (reduced 
by any undeclared earned income per share that is expected to be declared 
shortly after the end of the period) multiplied by the average number of Fund 
shares outstanding during the period that were entitled to dividends. This 
amount is added to 1 and raised to the sixth power. 1 is then subtracted from 
the result and the difference is multiplied by 2 to arrive at the annualized 
yield. 

   
   To determine interest income from debt obligations, a yield-to-maturity, 
expressed as a percentage, is determined for obligations held at the 
beginning of the period, based on the current market value of the security 
plus accrued interest, generally as of the end of the month preceding the 
30-day period, or, for obligations purchased during the period, based on the 
cost of the security (including accrued interest). The yield-to-maturity is 
multiplied by the market value (plus accrued interest) for each security and 
the result is divided by 360 and multiplied by 30 days or the number of days 
the security was held during the period, if less. Modifications are made for 
determining yield-to-maturity on certain tax-exempt securities. For the 
30-day period ended December 31, 1996, the Fund's yield, calculated pursuant 
to the formula described above, was 4.69%. 

   The Fund may also quote a "tax-equivalent yield" determined by dividing 
the tax-exempt portion of quoted yield by 1 minus the stated income tax rate 
and adding the result to the portion of the yield that is not tax-exempt. The 
Fund's tax-equivalent yield, based upon a Federal personal income tax bracket 
of 39.60% (the highest current individual marginal tax rate), for the 30-day 
period ended December 31, 1996 was 7.76% based upon the yield quoted above. 
    

   The Fund's "average annual total return" represents an annualization of 
the Fund's total return over a particular period and is computed by finding 
the annual percentage rate which will result in the ending redeemable value 
of a hypothetical $1,000 investment made at the beginning of a one, five or 
ten year period, or for the period from the date of commencement of the 
Fund's operations, if shorter than any of the foregoing. For the purpose of 
this calculation, it is assumed that all dividends and distributions are 
reinvested. The formula for computing the average annual total return 
involves a percentage obtained by dividing the ending redeemable value by the 
amount of the initial investment, taking a root of the quotient (where the 
root is equivalent to the number of years in the period) and subtracting 1 
from the result. 

   
   The average annual total returns of the Fund for the year ended December 
31, 1996, for the five years ended December 31, 1996, and for the ten years 
ended December 31, 1996, were - 0.53%, 6.00% and 7.00%, 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 calculation may or may not reflect 
the imposition of the maximum front-end 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 in the preceding 
paragraph, but without the deduction for any applicable sales charge. Based 
on this calculation, the Fund's average annual total return for the year 
ended December 31, 1996 was 3.61%, the average annual total return for the 
five years ended December 31, 1996 was 6.86% and the average annual total 
return for the ten years ended December 31, 1996 was 7.44%. 
    

   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 
reduction for any sales charge) by the initial $1,000 

                                       28
<PAGE>

   
investment and subtracting 1 from the result. Based on the foregoing 
calculation, the Fund's total return for the year ended December 31, 1996 was 
3.61%, the total return for five years ended December 31, 1996 was 39.37%, 
and the total return for the ten years ended December 31, 1996 was 104.87%. 

   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 and multiplying by $9,600, $48,375 or $97,250 
($10,000, $50,000 or $100,000 adjusted for a 4.0%, 3.25% or 2.75% sales 
charge, respectively). Investments of $10,000, $50,000 and $100,000, adjusted 
for the aforementioned sales charges, in the Fund at inception (March 27, 
1980) would have grown to $45,115, $227,338 and $457,026, respectively, at 
December 31, 1996. The Fund from time to time may also advertise its 
performance relative to certain performance rankings and indexes compiled by 
independent organizations. 
    

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

   
   The Shareholders of the Fund are entitled to a full vote for each full 
share of beneficial interest held. The Fund is authorized to issue an 
unlimited number of shares of beneficial interest. The shareholders of the 
Fund are entitled to a full vote for each full share held. All of the 
Trustees, except for Messrs. Bozic, Purcell and Schroeder, have been elected 
by the shareholders of the Fund, most recently at a Special Meeting of 
Shareholders held on January 12, 1993. Messrs. Bozic, Purcell and Schroeder 
were elected by the other Trustees of the Fund on April 8, 1994. The Trustees 
themselves have the power to alter the number and the terms of office of the 
Trustees (as provided for in the Declaration of Trust), 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 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 managed portfolios) and additional classes 
of shares within any series (which would be used to distinguish among the 
rights of different categories of shareholders, as might be required by 
future regulations or other unforeseen circumstances). The Trustees have not 
presently authorized any such additional series or classes of shares. 
    

   The Declaration of Trust further provides that no Trustee, officer, 
employee or agent of the Fund is liable to the Fund or to a shareholder, nor 
is any Trustee, officer, employee or agent liable to any third persons in 
connection with the affairs of the Fund, except as such liability may arise 
from his/her or its own bad faith, willful misfeasance, gross negligence, or 
reckless disregard of his 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 above, 
the Declaration of Trust provides that a Trustee, officer, employee or agent 
is entitled to be indemnified against all liability in connection with the 
affairs of the Fund. 

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

CUSTODIAN AND TRANSFER AGENT 
- ----------------------------------------------------------------------------- 

   The Bank of New York, 90 Washington Street, New York, New York 10286 is 
the Custodian of the Fund's assets. The Custodian has no part in deciding the 
Fund's investment policies or which securities are to be purchased or sold 
for the Fund's portfolio. Any of the Fund's cash balances with the Custodian 
in excess of $100,000 are unprotected by Federal deposit insurance. Such 
balances may, at times, be substantial.

   Dean Witter Trust Company, Harborside Financial Center, Plaza Two, Jersey 
City, New Jersey 07311 is the Transfer Agent of the Fund's shares and 
Dividend Disbursing Agent for payment of dividends and distributions on Fund 
shares and Agent for shareholders under various investment plans described 
herein. Dean Witter Trust Company is an affiliate of Dean Witter InterCapital 
Inc., the Fund's Investment Manager, and Dean Witter Distributors Inc., the

DEAN WITTER TAX-EXEMPT SECURITIES TRUST 
NOTES TO FINANCIAL STATEMENTS December 31, 1996 

1. ORGANIZATION AND ACCOUNTING POLICIES 

Dean Witter Tax-Exempt Securities Trust (the "Fund") is registered under the 
Investment Company Act of 1940, as amended, as a diversified, open-end 
management investment company. The Fund's investment objective is to provide 
a high level of current income which is exempt from federal income tax, 
consistent with the preservation of capital. The Fund was incorporated in 
Maryland in 1979, commenced operations on March 27, 1980 and reorganized as a 
Massachusetts business trust on April 30, 1987. 

The preparation of financial statements in accordance with generally accepted 
accounting principles requires management to make estimates and assumptions 
that affect the reported amounts and disclosures. Actual results could differ 
from those estimates. 

The following is a summary of significant accounting policies: 

A. VALUATION OF INVESTMENTS -- Portfolio securities are valued for the Fund 
by an outside independent pricing service approved by the Trustees. The 
pricing service has informed the Fund that in valuing the Fund's portfolio 
securities, it uses both a computerized matrix of tax-exempt securities and 
evaluations by its staff, in each case based on information concerning market 
transactions and quotations from dealers which reflect the bid side of the 
market each day. The Fund's portfolio securities are thus valued by reference 
to a combination of transactions and quotations for the same or other 
securities believed to be comparable in quality, coupon, maturity, type of 
issue, call provisions, trading characteristics and other features deemed to 
be relevant. Short-term debt securities having a maturity date of more than 
sixty days at time of purchase are valued on a mark-to-market basis until 
sixty days prior to maturity and thereafter at amortized cost based on their 
value on the 61st day. Short-term debt securities having a maturity date of 
sixty days or less at the time of purchase are valued at amortized cost. 

B. ACCOUNTING FOR INVESTMENTS -- Security transactions are accounted for on 
the trade date (date the order to buy or sell is executed). Realized gains 
and losses on security transactions are determined by the identified cost 
method. The Fund amortizes premiums and accretes discounts over the life of 
the respective securities. Interest income is accrued daily.

and net realized capital gains are determined in accordance with federal 
income tax regulations which may differ from generally accepted accounting 
principles. These "book/tax" differences are either considered temporary or 
permanent in nature. To the extent these differences are permanent in nature, 
such amounts are reclassified within the capital accounts based on their 
federal tax-basis treatment; temporary differences do not require 
reclassification. Dividends and distributions which exceed net investment 
income and net realized capital gains for financial reporting purposes but 
not for tax purposes are reported as dividends in excess of net investment 
income or distributions in excess of net realized capital gains. To the 
extent they exceed net investment income and net realized capital gains for 
tax purposes, they are reported as distributions of paid-in-capital. 

2. INVESTMENT MANAGEMENT AGREEMENT 

Pursuant to an Investment Management Agreement with Dean Witter InterCapital 
Inc. (the "Investment Manager"), the Fund pays the Investment Manager a 
management fee, accrued daily and payable monthly, by applying the following 
annual rates to the Fund's net assets determined as of the close of each 
business day: 0.50% to the portion of daily net assets not exceeding $500 
million; 0.425% to the portion of daily net assets exceeding $500 million but 
not exceeding $750 million; 0.375% to the portion of daily net assets 
exceeding $750 million but not exceeding $1 billion; 0.35% to the portion of 
daily net assets exceeding $1 billion but not exceeding $1.25 billion; and 
0.325% to the portion of daily net assets exceeding $1.25 billion. 

Under the terms of the Agreement, in addition to managing the Fund's 
investments, the Investment Manager maintains certain of the Fund's books and 
records and furnishes, at its own expense, office space, facilities, 
equipment, clerical, bookkeeping and certain legal services and pays the 
salaries of all personnel, including officers of the Fund who are employees 
of the Investment Manager. The Investment Manager also bears the cost of 
telephone services, heat, light, power and other utilities provided to the 
Fund.

REPORT OF INDEPENDENT ACCOUNTANTS 

TO THE SHAREHOLDERS AND TRUSTEES 
OF DEAN WITTER TAX-EXEMPT 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 
Tax-Exempt Securities Trust (the "Fund") at December 31, 1996, the results of 
its operations for the year then ended, the changes in its net assets for 
each of the two years in the period then ended and the financial highlights 
for each of the ten years in the period then ended, in conformity with 
generally accepted accounting principles. These financial statements and 
financial highlights (hereafter referred to as "financial statements") are 
the responsibility of the Fund's management; our responsibility is to express 
an opinion on these financial statements based on our audits. We conducted 
our audits of these financial statements in accordance with generally 
accepted auditing standards which require that we plan and perform the audit 
to obtain reasonable assurance about whether the financial statements are 
free of material misstatement. An audit includes examining, on a test basis, 
evidence supporting the amounts and disclosures in the financial statements, 
assessing the accounting principles used and significant estimates made by 
management, and evaluating the overall financial statement presentation. We 
believe that our audits, which included confirmation of securities at 
December 31, 1996 by correspondence with the custodian and brokers, provide a 
reasonable basis for the opinion expressed above.

RATINGS OF INVESTMENTS 
- ----------------------------------------------------------------------------- 

Moody's Investors Service Inc. ("Moody's") 

                            MUNICIPAL BOND RATINGS 

<TABLE>
<CAPTION>
<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 in
         the future. Uncertainty of position characterizes bonds in this class.

B        Bonds which are rated B generally lack characteristics of a desirable
         investment. Assurance of interest and principal payments or of
         maintenance of other terms of the contract over any long period of
         time may be small.

Caa      Bonds which are rated Caa are of poor standing. Such issues may be in
         default or there may be present elements of danger with respect to
         principal or interest.

Ca       Bonds which are rated Ca present obligations which are speculative in
         a high degree. Such issues are often in default or have other marked
         shortcomings.

C        Bonds which are rated C are the lowest rated class of bonds, and
         issues so rated can be regarded as having extremely poor prospects of
         ever attaining any real investment standing.
</TABLE>

   Conditional Rating: Bonds for which the security depends upon the 
completion of some act or the fulfillment of some condition are rated 
conditionally. These bonds are 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. 

                                       46
<PAGE>

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

                            MUNICIPAL NOTE RATINGS 

   Moody's ratings for state and municipal note and other short-term loans 
are designated Moody's Investment Grade (MIG). MIG 1 denotes best quality and 
means there is present strong protection from established cash flows, 
superior liquidity support or demonstrated broad-based access to the market 
for refinancing. MIG 2 denotes high quality and means that margins of 
protection are ample although not as large as in MIG 1. MIG 3 denotes 
favorable quality and means that all security elements are accounted for but 
that the undeniable strength of the previous grades, MIG 1 and MIG 2, is 
lacking. MIG 4 denotes adequate quality and means that the protection 
commonly regarded as required of an investment security is present and that 
while the notes are not distinctly or predominantly speculative, there is 
specific risk. 

                       VARIABLE RATE DEMAND OBLIGATIONS 

   A short-term rating, in addition to the Bond or MIG ratings, designated 
VMIG may also be assigned to an issue having a demand feature. The assignment 
of the VMIG symbol reflects such characteristics as payment upon periodic 
demand rather than fixed maturity dates and payment relying on external 
liquidity. The VMIG rating criteria are identical to the MIG criteria 
discussed above. 

                           COMMERCIAL PAPER RATINGS 

   Moody's Commercial Paper ratings are opinions of the ability to repay 
punctually promissory obligations not having an original maturity in excess 
of nine months. These ratings apply to Municipal Commercial Paper as well as 
taxable Commercial Paper. Moody's employs the following three designations, 
all judged to be investment grade, to indicate the relative repayment 
capacity of rated issuers: Prime-1, Prime-2, Prime-3. 

   Issuers rated Prime-1 have a superior capacity for repayment of short-term 
promissory obligations. Issuers rated Prime-2 have a strong capacity for 
repayment of short-term promissory obligations; and Issuers rated Prime-3 
have an acceptable capacity for repayment of short-term promissory 
obligations. Issuers rated Not Prime do not fall within any of the Prime 
rating categories. 

STANDARD & POOR'S CORPORATION ("STANDARD & POOR'S") 

                            MUNICIPAL BOND RATINGS 

   A Standard & Poor's municipal bond rating is a current assessment of the 
creditworthiness of an obligor with respect to a specific obligation. This 
assessment may take into consideration obligors such as guarantors, insurers 
or lessees. 

   The ratings are based on current information furnished by the issuer or 
obtained by Standard & Poor's from other sources it considers reliable. The 
ratings are based, in varying degrees, on the following considerations: (1) 
likelihood of default-capacity and willingness of the obligor as to the 
timely payment of interest and repayment of principal in accordance with the 
terms of the obligation; (2) nature of and provisions of the obligation; and 
(3) protection afforded by, and relative position of the obligation in the 
event of bankruptcy, reorganization or other arrangement under the laws of

   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. 

                                       47

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 eibits adequate
         protection parameters, adverse economic conditions or changing
         circumstances are more likely to lead to a weakened capacity to pay
         interest and repay principal for debt in this category than for debt
         in higher-rated categories. Bonds rated AAA, AA, A and BBB are
         considered investment grade bonds.

BB       Debt rated "BB" has less near-term vulnerability to default than other
         speculative grade debt. However, it faces major ongoing uncertainties
         or exposure to adverse business, financial or economic conditions
         which would lead to inadequate capacity or willingness to pay interest
         and repay principal.

B        Debt rated "B" has a greater vulnerability to default but presently
         has the capacity to meet interest payments and principal repayments.
         Adverse business, financial or economic conditions would likely impair
         capacity or willingness to pay interest and repay principal.

CCC      Debt rated "CCC" has a current identifiable vulnerability to default,
         and is dependent upon favorable business, financial and economic
         conditions to meet timely payments of interest and repayments of
         principal. In the event of adverse business, financial or economic
         conditions, it is not likely to have the capacity to pay interest and
         repay principal.

CC       The rating "CC" is typically applied to debt subordinated to senior
         debt which is assigned an actual or implied "CCC" rating.

C        The rating "C" is typically applied to debt subordinated to senior
         debt which is assigned an actual or implied "CCC-" debt rating.

Cl       The rating "Cl" is reserved for income bonds on which no interest is
         being paid.

D        Debt rated "D" is in payment default. The 'D' rating category is used
         when interest payments or principal payments are not made on the date
         due even if the applicable grace period has not expired, unless S&P
         believes that such payments will be made during such grace period. The
         'D' rating also will be used upon the filing of a bankruptcy petition
         if debt service payments are jeopardized.

NR       Indicates that no rating has been requested, that there is
         insufficient information on which to base a rating or that Standard &
         Poor's does not rate a particular type of obligation as a matter of
         policy.

         Bonds rated "BB", "B", "CCC", "CC" and "C" are regarded as having
         predominantly speculative characteristics with respect to capacity to
         pay interest and repay principal. "BB" indicates the least degree of
         speculation and "C" the highest degree of speculation. While such debt
         will likely have some quality and protective characteristics, these
         are outweighed by large uncertainties or major risk exposures to
         adverse conditions.

         Plus (+) or minus(-): The ratings from "AA" to "CCC" may be modified
         by the addition of a plus or minus sign to show relative standing
         within the major ratings categories.

                                       48
<PAGE>

         The foregoing ratings are sometimes followed by a "p" which indicates
         that the rating is provisional. A provisional rating assumes the
         successful completion of the project being financed by the bonds being
         rated and indicates that payment of debt service requirements is
         largely or entirely dependent upon the successful and timely
         completion of the project. This rating, however, while addressing
         credit quality subsequent to completion of the project, makes no
         comment on the likelihood or risk of default upon failure of such
         completion.

                            MUNICIPAL NOTE RATINGS 

   Commencing on July 27, 1984, Standard & Poor's instituted a new rating 
category with respect to certain municipal note issues with a maturity of 
less than three years. The new note ratings denote the following: 

         SP-1 denotes a very strong or strong capacity to pay principal and 
    interest. Issues determined to possess overwhelming safety characteristics 
    are given a plus (+) designation (SP-1+). 

         SP-2 denotes a satisfactory capacity to pay principal and interest. 

         SP-3 denotes a speculative capacity to pay principal and interest. 

                           COMMERCIAL PAPER RATINGS 

   Standard and Poor's commercial paper rating is a current assessment of the 
likelihood of timely payment of debt having an original maturity of no more 
than 365 days. The commercial paper rating is not a recommendation to 
purchase or sell a security. The ratings are based upon current information 
furnished by the issuer or obtained by 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. 

      A-1 indicates that the degree of safety regarding timely payments is very 
    strong. 

      A-2 indicates capacity for timely payment on issues with this designation 
    is strong. However, the relative degree of safety is not as overwhelming 
    as for issues designated "A-1". 

      A-3 indicates a satisfactory capacity for timely payment. Obligations 
    carrying this designation are, however, somewhat more vulnerable to the 
    adverse effects of changes in circumstances than obligations carrying the 
    higher designations.

Item 27. Indemnification.

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

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

         Insofar as indemnification for liabilities arising under the
Securities Act of 1933 (the "Act") may be permitted to trustees, officers and
controlling persons of the Registrant pursuant to the foregoing provisions or
otherwise, the Registrant has been advised that in the

                                       2

<PAGE>



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

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

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

(25%) of all the votes entitled to be cast at such meeting. Such request 
shall state the purpose or purposes of such meeting and the matters proposed 
to be acted on thereat. The Secretary shall inform such Shareholders of the 
reasonable estimated cost of preparing and mailing such notice of the 
meeting, and upon payment to the Trust of such costs, the Secretary shall 
give notice stating the purpose or purposes of the meeting to all entitled to 
vote at such meeting. No meeting need be called upon the request of the 
holders of Shares entitled to cast less than a majority of all votes entitled 
to be cast at such meeting, to consider any matter which is substantially the 
same as a matter voted upon at any meeting of Shareholders held during the 
preceding twelve months. 

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

   SECTION 3.4. Quorum and Adjournment of Meetings. Except as otherwise 
provided by law, by the Declaration or by these By-Laws, at all meetings of 
Shareholders the holders of a majority of the Shares issued and outstanding 
and entitled to vote thereat, present in person or represented by proxy, 
shall be requisite and shall constitute a quorum for the transaction of 
business. In the absence of a quorum, the 

                                
           
<PAGE>
Shareholders present or represented by proxy and entitled to vote thereat 
shall have power to adjourn the meeting from time to time. Any adjourned 
meeting may be held as adjourned without further notice. At any adjourned 
meeting at which a quorum shall be present, any business may be transacted as 
if the meeting had been held as originally called. 

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

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

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

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

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

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

                                  ARTICLE IV 
                                   TRUSTEES 

   SECTION 4.1. Meetings of the Trustees. The Trustees may in their 
discretion provide for regular or special meetings of the Trustees. Regular 
meetings of the Trustees may be held at such time and place as shall be 
determined from time to time by the Trustees without further notice. Special 
meetings of the Trustees may be called at any time by the President and shall 
be called by the President or the Secretary upon the written request of any 
two (2) Trustees. 

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

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

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

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

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

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

   SECTION 4.8. Indemnification of Trustees, Officers, Employees and 
Agents. (a) The Trust shall indemnify any person who was or is a party or is 
threatened to be made a party to any threatened, pending, or completed 
action, suit or proceeding, whether civil, criminal, administrative or 
investigative (other than an action by or in the right of the Trust) by 
reason of the fact that he is or was a Trustee, officer, employee, or agent 
of the Trust. The indemnification shall be against expenses, including 
attorneys' fees, judgments, fines, and amounts paid in settlement, actually 
and reasonably incurred by him in connection with the action, suit, or 
proceeding, if he acted in good faith and in a manner he reasonably believed 
to be in or not opposed to the best interests of the Trust, and, with respect 
to any criminal action or proceeding, had no reasonable cause to believe his 
conduct was unlawful. The termination of any action, suit or proceeding by 
judgment, order, settlement, conviction, or upon a plea of nolo contendere or 
its equivalent, shall not, of itself, create a presumption that the person 
did not act in good faith and in a manner which he reasonably believed to be 
in or not opposed to the best interests of the Trust, and, with respect to 
any criminal action or proceeding, had reasonable cause to believe that his 
conduct was unlawful. 

                                3           
<PAGE>
   (b) The Trust shall indemnify any person who was or is a party or is 
threatened to be made a party to any threatened, pending or completed action 
or suit by or on behalf of the Trust to obtain a judgment or decree in its 
favor by reason of the fact that he is or was a Trustee, officer, employee, 
or agent of the Trust. The indemnification shall be against expenses, 
including attorneys' fees actually and reasonably incurred by him in 
connection with the defense or settlement of the action or suit, if he acted 
in good faith and in a manner he reasonably believed to be in or not opposed 
to the best interests of the Trust; except that no indemnification shall be 
made in respect of any claim, issue, or matter as to which the person has 
been adjudged to be liable for negligence or misconduct in the performance of 
his duty to the Trust, except to the extent that the court in which the 
action or suit was brought, or a court of equity in the county in which the 
Trust has its principal office, determines upon application that, despite the 
adjudication of liability but in view of all circumstances of the case, the 
person is fairly and reasonably entitled to indemnity for those expenses 
which the court shall deem proper, provided such Trustee, officer, employee 
or agent is not adjudged to be liable by reason of his willful misfeasance, 
bad faith, gross negligence or reckless disregard of the duties involved in 
the conduct of his office. 

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

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

       (2) The determination shall be made: 

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

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

        (iii) By the Shareholders.

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

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

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

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

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

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

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

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

                                4           
<PAGE>
          (3) either, (i) such person provides a security for his undertaking,
     or

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

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

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

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

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

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

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

                                  ARTICLE V 
                                  COMMITTEES 

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

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

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

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

setting forth the action shall be signed by all members of the Committee 
entitled to vote upon the action and such written consent is filed with the 
records of the proceedings of the Committee.

   SECTION 6.1. Executive Officers. The executive officers of the Trust shall 
be a Chairman, a President, one or more Vice Presidents, a Secretary and a

from time to time deem advisable. 

   SECTION 6.3. Term and Removal and Vacancies. Each officer of the Trust 
shall hold office until his successor is elected and has qualified. Any 
officer or agent of the Trust may be removed by the Trustees whenever, in 
their judgment, the best interests of the Trust will be served thereby, but 
such removal shall be without prejudice to the contractual rights, if any, of 
the person so removed. 

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

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

the Trustees. The Vice President, or, if there be more than one, the Vice 
Presidents in the order of their seniority as may be determined from time to 
time by the Trustees or the President, shall, in the absence or disability of 
the President, exercise the powers and perform the duties of the President,

the Trustees and all meetings of the Shareholders and record all the 
proceedings of the meetings of the Shareholders and of the Trustees in a book 
to be kept for that purpose, and shall perform like duties for the standing

requiring it, and, when so affixed, it shall be attested by his signature or

officer of the Trust. He shall keep or cause to be kept full and accurate 
accounts of receipts and disbursements in books belonging to the Trust, and 
he shall render to the Trustees and the President, whenever any of them 
require it, an account of his transactions as Treasurer and of the financial 
condition of the Trust; and he shall perform such other duties as the 
Trustees, or the President, may from time to time prescribe.

the Treasurer and shall perform such other duties and have such other powers 
as the Trustees, or the President, may from time to time prescribe. 

   SECTION 6.14. Delegation of Duties. Whenever an officer is absent or 
disabled, or whenever for any reason the Trustees may deem it desirable, the 
Trustees may delegate the powers and duties of an officer or officers to any 
other officer or officers or to any Trustee or Trustees. 

                                 ARTICLE VII 
                         DIVIDENDS AND DISTRIBUTIONS 

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

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

                                 ARTICLE VIII 
                            CERTIFICATES OF SHARES 

   SECTION 8.1. Certificates of Shares. Certificates for Shares of each 
series or class of Shares shall be in such form and of such design as the 
Trustees shall approve, subject to the right of the Trustees to change such 
form and design at any time or from time to time, and shall be entered in the 
records of the Trust as they are issued. Each such certificate shall bear a 
distinguishing number; shall exhibit the holders' name and certify the number 
of full Shares owned by such holder; shall be signed by or in the name of 

                                7           
<PAGE>
the Trust by the President, or a Vice President, and countersigned by the 
Secretary or an Assistant Secretary or the Treasurer and an Assistant 
Treasurer of the Trust; shall be sealed with the seal; and shall contain such 
recitals as may be required by law. Where any certificate is signed by a 
Transfer Agent or by a Registrar, the signature of such officers and the seal 
may be facsimile, printed or engraved. The Trust may, at its option, 
determine not to issue a certificate or certificates to evidence Shares owned 
of record by any Shareholder. 

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

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

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

                                  CUSTODIAN 

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

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

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

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

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

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

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

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

to make a determination of Shareholders for any other proper purpose. Such 
date, in any case, shall be not more than ninety (90) days, and in case of a 
meeting of Shareholders not less than ten (10) days, prior to the date on 
which particular action requiring such determination of Shareholders is to be

transfer books shall be closed for a stated period but not to exceed, in any 
case, twenty (20) days. If the transfer books are closed for the purpose of 
determining Shareholders entitled to notice of a vote at a meeting of 
Shareholders, such books shall be closed for at least ten (10) days 
immediately preceding such meeting. 

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

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

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

                     COMPLIANCE WITH FEDERAL REGULATIONS 

   The Trustees are hereby empowered to take such action as they may deem to 
be necessary, desirable or appropriate so that the Trust is or shall be in 
compliance with any federal or state statute, rule or regulation with which 
compliance by the Trust is required.

   These By-Laws may be amended, altered, or repealed, or new By-Laws may be 
adopted, (a) by a Majority Shareholder Vote, or (b) by the Trustees;

apparent inconsistency shall be construed in favor of the related provisions 
in the Declaration.

                         AMENDMENT TO CUSTODY AGREEMENT


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

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

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

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

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

         IN WITNESS WHEREOF, the parties hereto have caused this Amendment to
be executed by their respective Officers, thereunto duly authorized and their
respective seals to be hereunto affixed, as of the day and year first above
written.
