OBJECTIVE            current income while maintaining relatively low volatility of 
                     principal. 
- --------------------------------------------------------------------------------------- 
MANAGER              Dean Witter Services Company Inc. (the "Manager"), a wholly-owned 
                     subsidiary of Dean Witter InterCapital Inc. ("InterCapital"), is 
                     the Fund's manager. The Manager also serves as Manager to thirteen 
                     other investment companies which are advised by TCW Funds 
                     Management, Inc. (the "TCW/DW Funds"). The Manager and 
                     InterCapital serve in various investment management, advisory, 
                     management and administrative capacities to a total of 103

                     approximately $102.9 billion at December 31, 1997. 
- ---------------------------------------------------------------------------------------

                     investment adviser to thirteen other TCW/DW Funds. As of December

                     billion under management or committed to management in various 
                     fiduciary or advisory capacities, primarily from institutional

DISTRIBUTOR AND     The Fund is authorized to reimburse Dean Witter Distributors Inc., the Fund's Distributor, for specific 
PLAN OF             expenses incurred in promoting the distribution of the Fund's shares, including personal services to 
DISTRIBUTION        shareholders and maintenance of shareholder accounts, in accordance with a Plan of Distribution pursuant to 
                    Rule 12b-1 under the Investment Company Act of 1940. Reimbursement may in no event exceed an amount equal to 
                    payments at an annual rate of 0.75% of the average daily net assets of the Fund (see page 22). 
- -------------------------------------------------------------------------------------------------------------------------- 
REDEMPTION          Shares are redeemable by the shareholder at net asset value. An account may be involuntarily redeemed if 
                    the total value of the account is less than $100 or, if the account was opened through EasyInvest (Service 
                    Mark), if after twelve months the shareholder has invested less than $1,000 in the account (see page 25). 
- -------------------------------------------------------------------------------------------------------------------------- 
SPECIAL             The net asset value of the Fund's shares will fluctuate with changes in the market value of its portfolio 
RISK                securities. A decline in prevailing interest rates will generally increase the value of fixed-income 
CONSIDERATIONS      securities, while an increase in rates usually reduces the value of those securities. The Fund's yield also
                    will vary based on the yield of the Fund's portfolio securities. The Fund may invest in mortgage-backed 
                    securities issued in the United States and Canada; these securities have different characteristics than 
                    traditional debt securities, primarily in that interest and principal payments are made more frequently, 
                    usually monthly, and that principal may be prepaid at any time. Certain derivative mortgage-backed securities 
                    in which the Fund invests are extremely sensitive to changes in interest rates and in prepayment rates on the 
                    underlying mortgage assets, and as a result may be highly volatile (see page 13). The Canadian mortgage-backed 
                    securities market is of recent origin and is less well developed and less liquid than the U.S. market. The Fund
                    may invest a significant portion of its assets in securities issued and guaranteed by the governments of Canada 
                    and Mexico. It should be recognized that the Canadian and Mexican debt securities in which the Fund will 
                    invest pose different and greater risks than those customarily associated with U.S. debt securities, including 
                    (i) the risks associated with international investments generally, such as fluctuations in foreign currency 
                    exchange rates, (ii) the risks of investing in Canada and Mexico, which have smaller, less liquid debt markets,
                    such as limited liquidity, price volatility, custodial and settlement issues, and (iii) specific risks 
                    associated with the Mexican economy, including high levels of inflation, large amounts of debt and political and
                    social uncertainties (see page 14). The Fund is a non-diversified investment company and, as such, is not
                    subject to the diversification requirements of the Investment Company Act of 1940. As a result, a relatively
                    high percentage of the Fund's assets may be invested in a limited number of issuers. However, the Fund intends
                    to continue to qualify as a regulated investment company under the federal income tax laws and, as such, 
                    is subject to the diversification requirements of the Internal Revenue Code (see page 15). In addition, 
                    the Fund may utilize certain investment techniques, including forward foreign currency exchange contracts, 
                    options and futures, and the speculative technique known as leverage through the use of reverse repurchase 
                    agreements and dollar rolls, which entail additional risks (see pages 13-20).

   THE ABOVE EXAMPLE SHOULD NOT BE CONSIDERED A REPRESENTATION OF PAST OR 
FUTURE EXPENSES OR PERFORMANCE. ACTUAL EXPENSES OF THE FUND MAY BE MORE OR 
LESS THAN THOSE SHOWN. 

   The purpose of this table is to assist the investor in understanding the 
various costs and expenses that an investor in the Fund will bear directly or 
indirectly. For a more complete description of these costs and expenses, see 
"The Fund and its Management" and "Purchase of Fund Shares--Plan of 
Distribution" in this Prospectus. 

   Long-term shareholders of the Fund may pay more in distribution fees than 
the economic equivalent of the maximum front-end sales charges permitted by 
the NASD.

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

   TCW/DW North American Government Income Trust (the "Fund") is an open-end, 
non-diversified management investment company. The Fund is a trust of the 
type commonly known as a "Massachusetts business trust" and was organized 
under the laws of Massachusetts on February 19, 1992. 

   
   Dean Witter Services Company Inc. (the "Manager"), whose address is Two 
World Trade Center, New York, New York 10048, is the Fund's Manager. The 
Manager is a wholly-owned subsidiary of Dean Witter InterCapital Inc. 
("InterCapital"). InterCapital is a wholly-owned subsidiary of Morgan 
Stanley, Dean Witter, Discover & Co., a preeminent global financial services 
firm that maintains leading market positions in each of its three primary 
businesses--securities, asset management and credit services. 

   The Manager acts as manager to thirteen other TCW/DW Funds. The Manager 
and InterCapital act in various investment management, advisory, management 
and administrative capacities to a total of 103 investment companies, 
twenty-nine of which are listed on the New York Stock Exchange, with combined 
assets of approximately $98.9 billion as of December 31, 1997. InterCapital 
also manages and advises portfolios of pension plans, other institutions and 
individuals which aggregated approximately $4 billion at such date. 
    

   The Fund has retained the Manager to manage its business affairs, 
supervise its overall day-to-day operations (other than providing investment 
advice) and provide all administrative services. 

   
   TCW Funds Management, Inc. (the "Adviser"), whose address is 865 South 
Figueroa Street, Suite 1800, Los Angeles, California 90017, is the Fund's 
investment adviser. The Adviser was organized in 1987 as a wholly-owned 
subsidiary of The TCW Group, Inc. ("TCW"), whose subsidiaries, including 
Trust Company of the West and TCW Asset Management Company, provide a variety 
of trust, investment management and investment advisory services. Robert A. 
Day, who is Chairman of the Board of Directors of TCW, may be deemed to be a 
control person of the Adviser by virtue of the aggregate ownership of Mr. Day 
and his family of more than 25% of the outstanding voting stock of TCW. The 
Adviser serves as investment adviser to thirteen other TCW/DW Funds in 
addition to the Fund. As of December 31, 1997, the Adviser and its affiliated 
companies had approximately $50 billion under man-agement or committed to 
management, primarily from institutional investors. 
    

   The Fund has retained the Adviser to invest the Fund's assets. 

   The Fund's Trustees review the various services provided by the Manager 
and the Adviser 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 Manager, the Fund pays the 
Manager monthly compensation calculated daily by applying the annual rate of 
0.39% to the Fund's net assets up to $3 billion, scaled down to 0.36% on 
assets over $3 billion. As compensation for its investment advisory services, 
the Fund pays the Adviser monthly compensation calculated daily by applying 
an annual rate of 0.26% to the Fund's net assets up to $3 billion, scaled 
down to 0.24% on assets over $3 billion. For the fiscal year ended October 
31, 1997, the Fund accrued total compensation to the Manager and the Adviser 
amounting to 0.39% and 0.26%, respectively, of the Fund's average daily net 
assets. During that period, the Fund's total expenses amounted to 1.65% of 
the Fund's average daily net assets.

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

   The investment objective of the Fund is to earn a high level of current 
income while maintaining relatively low volatility of principal. This 
objective is fundamental and may not be changed without shareholder approval. 
There is no assurance that the objective will be achieved. 

   The Fund seeks to achieve its investment objective by investing under 
normal circumstances at least 65% of its total assets in investment grade 
fixed-income securities issued or guaranteed by the U.S., Canadian or Mexican 
governments or their subdivisions, or the agencies or instrumentalities of 
any of the foregoing ("Government Securities"). In the case of the United 
States and Canada, a substantial portion of such investments will be fixed 
rate and adjustable rate mortgage-backed securities, including collateralized 
mortgage obligations ("Mortgage-Backed Securities"). The term investment 
grade consists of fixed-income securities rated Baa or higher by Moody's 
Investors Service, Inc. ("Moody's") or BBB or higher by Standard & Poor's 
Corporation ("S&P") or, if not rated, determined to be of comparable quality 
by the Adviser. Investments in securities 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. If a fixed-income 
security held by the Fund is rated BBB or Baa and is subsequently downgraded 
by a rating agency, the Fund will retain such security in its portfolio until 
the Adviser determines that it is practicable to sell the security without 
undue market or tax consequences to the Fund. In the event that such 
downgraded securities constitute 5% or more of the Fund's total assets, the 
Adviser will seek to sell immediately sufficient securities to reduce the 
total to below 5%. A description of fixed-income security ratings is 
contained in the Appendix to the Statement of Additional Information. 

   The Fund may invest up to 35% of its total assets in securities which are 
not Government Securities, including corporate debt securities and securities 
backed by other assets, such as automobile or credit card receivables and 
home equity loans ("Asset-Backed Securities"), and money market instruments, 
which are short-term (maturities of up to thirteen months) fixed-income 
securities, issued by private institutions. Such securities (except for 
Eurodollar certificates of deposit) must be issued by U.S., Canadian or 
Mexican issuers and (except for money market instruments) must be rated at 
least Aa by Moody's or AA by S&P or, if not rated, determined to be of 
comparable quality by the Adviser. 

   The Fund expects that under normal circumstances the market value dollar 
weighted average life (or period until the next reset date) of the Fund's 
portfolio securities will be no greater than three years. In addition, the 
Fund will purchase only Mexican Government Securities with remaining 
maturities of one year or less. The Fund seeks to achieve relatively low 
volatility by investing in a portfolio of securities which the Adviser 
believes will, in the aggregate, be resistant to significant fluctuations in 
market value. Although the values of fixed-income securities generally 
increase during periods of declining interest rates and decrease during 
periods of increasing interest rates, the extent of these fluctuations has 
historically generally been smaller for short term securities than for 
securities with longer maturities. Conversely, the yield available on shorter 
term securities has also historically been lower on average than those 
available from longer term securities. 

   Under normal circumstances the Fund will invest at least 50% of its total 
assets in U.S. Government Securities. The Fund will invest no more than 25% 
of its total assets in Canadian Government Securities and no more than 25% of 
its total assets in Mexican Government Securities. Subject to the foregoing 
guidelines, the Adviser will invest the Fund's assets, and allocate its 
investments from time to time among U.S., Canadian and Mexican Government 
Securities, based on its analysis of market conditions and changes in general 
economic conditions in the United States, Canada and Mexico. In such 
analysis, the Adviser will consider various factors, including its 
expectations 

                                7           
<PAGE>
regarding interest rate changes and changes in currency exchange rates among 
the U.S. dollar, the Canadian dollar and the Mexican peso, as well as general 
market, economic and political factors, to attempt to take advantage of 
favorable investment opportunities in each country. 

   Money market instruments in which the Fund may invest are securities 
issued or guaranteed by the U.S. Government (Treasury bills, notes and bonds, 
including zero coupon securities); obligations of banks subject to regulation 
by the U.S. Government and having total assets of $1 billion or more; 
Eurodollar certificates of deposit; obligations of savings banks and savings 
and loan associations having total assets of $1 billion or more; fully 
insured certificates of deposit; and commercial paper rated within the two 
highest grades by Moody's or S&P or, if not rated, issued by a company having 
an outstanding debt issue rated AAA by S&P or Aaa by Moody's. 

   In an effort to increase investment return or to hedge the Fund's 
portfolio, the Fund may engage in various investment techniques, including 
reverse repurchase agreements, dollar rolls, purchasing and selling call and 
put options, entering into futures contracts and related options, purchasing 
securities on a when-issued, delayed delivery or forward commitment basis and 
lending portfolio securities (see "Other Investment Policies" below). 

   There may be periods during which, in the opinion of the Adviser, market 
conditions warrant reduction of some or all of the Fund's securities 
holdings. During such periods, the Fund may adopt a temporary "defensive" 
posture in which greater than 35% of its total assets are invested in U.S. 
money market instruments or cash. 

GOVERNMENT SECURITIES 

   The Fund will invest at least 65% of its total assets in Government 
Securities. Government Securities are securities issued or guaranteed by the 
governments of the United States, Canada or Mexico, their political 
subdivisions and agencies and instrumentalities of any of the foregoing. Such 
securities may include U.S. Treasury securities, U.S. Mortgage-Backed 
Securities, the sovereign debt of Canada or any of its Provinces, Canadian 
Mortgage-Backed Securities, and the sovereign debt of Mexico or any of its 
government agencies. 

   A portion of the Government 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. For this reason, 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. 

   The zero coupon securities in which the Fund may invest are primarily 
Canadian Government Securities with remaining maturities of two years or less 
issued by Canadian provinces. Such securities generally are currently readily 
available only in the form of zero coupon securities. 

   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. However, 
the Fund will invest in zero coupon securities only when the Adviser believes 
that there will be cash in the Fund's portfolio representing return of 
principal on portfolio securities of the Fund at least equal to the imputed 
income on the zero coupon securities. The Adviser believes that a limited use 
of zero coupon securities in the Fund's portfolio may enable the Fund to 
increase the income available to shareholders (as a result of the yield 
premium often obtainable on such securities) without significantly increasing 
the volatility of the Fund's net asset value, although there is no assurance 
this can be achieved. 

                                8           
<PAGE>
The Fund intends to limit its use of zero coupon securities (other than 
Treasury bills with one year or less to maturity) to 10% of its total assets. 

UNITED STATES GOVERNMENT SECURITIES 

   Securities issued or guaranteed by the U.S. Government, its agencies or 
instrumentalities include: (i) U.S. Treasury obligations, all of which are 
backed by the full faith and credit of the United States and which differ 
only in their interest rates, maturities and times of issuance: U.S. Treasury 
bills (maturities of one year or less), U.S. Treasury notes (maturities of 
one to ten years), and U.S. Treasury bonds (generally maturities of greater 
than ten years); and (ii) obligations issued or guaranteed by U.S. Government 
agencies or instrumentalities, including government guaranteed 
Mortgage-Backed Securities, some of which are backed by the full faith and 
credit of the U.S. Treasury (e.g., Government National Mortgage Association 
direct pass-through certificates), some of which are supported by the right 
of the issuer to borrow from the U.S. Government (e.g., obligations of 
Federal Home Loan Banks), and some of which are backed only by the credit of 
the issuer itself (e.g., obligations of the Student Loan Marketing 
Association). The U.S. Government may also guarantee other debt obligations 
of special purpose borrowers. 

CANADIAN GOVERNMENT SECURITIES 

   Canadian Government Securities include securities issued or guaranteed by 
the Government of Canada, the Government of a Province of Canada or their 
agencies and Crown corporations. These securities may be denominated or 
payable in U.S. dollars or Canadian dollars. 

   The Bank of Canada, acting on behalf of the federal government, is 
responsible for the distribution of Government of Canada Treasury bills and 
federal bond issues. The Bank of Canada holds weekly auctions of Treasury 
bills (maturities of one year or less) and offers new issues of federal bonds 
through investment dealers and banks. An offering of Government of Canada 
bonds frequently consists of several different issues with various maturity 
dates, representing different segments of the yield curve and generally 
having maturities ranging from three to 25 years. The Bank of Canada usually 
purchases a previously announced amount of each offering of bonds. 
Mortgage-Backed Securities issued pursuant to the program established under 
the National Housing Act of Canada are also Canadian Government Securities 
because they benefit from a guarantee by the Canada Mortgage and Housing 
Corporation, but are not distributed by the Bank of Canada. 

   All Canadian Provinces have outstanding bond issues and several Provinces 
also guarantee bond issues of Provincial authorities, agencies and provincial 
Crown corporations. Spreads in the marketplace are determined by various 
factors, including the relative supply and the rating assigned by the rating 
agencies. Most Provinces also issue treasury bills. 

   Many municipalities and municipal financial authorities in Canada raise 
funds through the bond market in order to finance capital expenditures. 
Unlike U.S. municipal securities, which have special tax status, Canadian 
municipal securities have the same tax status as other Canadian Government 
Securities and trade similarly to such securities. The Canadian municipal 
market may be less liquid than the Provincial bond market. 

   The Fund will only invest in Canadian Government Securities which are 
rated at least A by Moody's or S&P, or, if not rated, are determined to be of 
comparable quality by the Adviser. 

MEXICAN GOVERNMENT SECURITIES 

   Mexican Government Securities include those securities which are issued or 
guaranteed by the Mexican Treasury or by Mexican government agencies or 
instrumentalities. These securities may be denominated and payable in Mexican 
pesos or U.S. dollars. 

   The debt market in Mexico began to develop rapidly after the promulgation 
of the Securities Market Law in 1975. Since 1975, the government has 
authorized a range of Mexican government issued debt securities, all of which 
are traded on the Mexican Stock Exchange: (i) Cetes--peso-denominated 
discount debt securities having maturities of two years or 

                                9           
<PAGE>
   
less sold through auctions regulated by Banco de Mexico; (ii) 
Bondes--peso-denominated long-term development bonds sold through auctions 
regulated by Banco de Mexico; (iii) Ajustabonos--peso-denominated bonds with 
a fixed coupon rate on a variable face amount which is adjusted in proportion 
to fluctuations in the Mexican consumer price index; and (iv) Nafinsa 
Pagares--peso denominated promissory notes, with maturities approximating 
those of Cetes, issued by the Nacional Financiera (Nafinsa), an agency of the 
Mexican government. 
    

   In addition, a variety of other special purpose bonds are issued by the 
Mexican federal government or its agencies, such as development bonds, bank 
indemnity bonds and urban renovation bonds, as well as bank development bonds 
and industrial development bonds. 

   The Fund will only invest in Mexican Government Securities which are rated 
at least Baa by Moody's or BBB by S&P or, if not rated, are determined to be 
of comparable quality by the Adviser. 

MORTGAGE-BACKED SECURITIES 

   Mortgage-Backed Securities are securities that directly or indirectly 
represent a participation in, or are secured by and payable from, mortgage 
loans secured by real property. The term Mortgage-Backed Securities as used 
herein includes adjustable rate mortgage securities and derivative mortgage 
products such as collateralized mortgage obligations, stripped 
Mortgage-Backed Securities and other products described below. 

U.S. MORTGAGE-BACKED SECURITIES 

   There are currently three basic types of U.S. Mortgage-Backed Securities: 
(i) those issued or guaranteed by the United States Government or one of its 
agencies or instrumentalities, such as the Government National Mortgage 
Association ("GNMA"), the Federal National Mortgage Association ("FNMA") and 
the Federal Home Loan Mortgage Corporation ("FHLMC") (securities issued by 
GNMA, but not those issued by FNMA or FHLMC, are backed by the "full faith 
and credit" of the United States); (ii) those issued by private issuers that 
represent an interest in or are collateralized by Mortgage-Backed Securities 
issued or guaranteed by the United States Government or one of its agencies 
or instrumentalities; and (iii) those issued by private issuers that 
represent an interest in or are collateralized by whole mortgage loans or 
Mortgage-Backed Securities without a government guarantee but usually having 
some form of private credit enhancement. The latter category of 
Mortgage-Backed Securities are not considered Government Securities for 
purposes of this Prospectus. 

   The mortgage pass-through securities in which the Fund may invest include 
those issued or guaranteed by GNMA, FNMA and FHLMC. GNMA certificates are 
direct obligations of the U.S. Government and, as such, are backed by the 
"full faith and credit" of the United States. FNMA is a federally chartered, 
privately owned corporation and FHLMC is a corporate instrumentality of the 
United States. FNMA and FHLMC certificates are not backed by the full faith 
and credit of the United States but the issuing agency or instrumentality has 
the right to borrow, to meet its obligations, from an existing line of credit 
with the U.S. Treasury. The U.S. Treasury has no legal obligation to provide 
such line of credit and may choose not to do so. Each of GNMA, FNMA and FHLMC 
guarantee timely distribution of interest to certificate holders. GNMA and 
FNMA also guarantee timely distribution of scheduled principal payments. 
FHLMC generally guarantees only the ultimate collection of principal of the 
underlying mortgage loans. 

   The Fund may also invest in adjustable rate mortgage securities, which are 
pass-through mortgage securities collateralized by mortgages with adjustable 
rather than fixed rates. 

   Collateralized Mortgage Obligations and Multiclass Pass-Through 
Securities. The Fund may invest in collateralized mortgage obligations or 
"CMOs." CMOs are debt obligations collateralized by mortgage loans or 
mortgage pass-through securities. Typically, CMOs are collateralized by GNMA, 
FNMA or FHLMC certificates, but also may be collateralized by whole loans or 
private mortgage pass-through securities (such collateral is collectively 
hereinafter referred to as 

                               10           
<PAGE>
"Mortgage Assets"). Multiclass pass-through securities are equity interests 
in a trust composed of Mortgage Assets. Payments of principal of and interest 
on the Mortgage Assets, and any reinvestment income thereon, provide the 
funds to pay debt service on the CMOs or make scheduled distributions on the 
multiclass pass-through securities. CMOs may be issued by agencies or 
instrumentalities of the United States Government, or by private originators 
of, or investors in, mortgage loans, including savings and loan associations, 
mortgage banks, commercial banks, investment banks and special purpose 
subsidiaries of the foregoing. The issuer of a series of CMOs may elect to be 
treated as a Real Estate Mortgage Investment Conduit ("REMIC"). REMICs 
include governmental and/or private entities that issue a fixed pool of 
mortgages secured by an interest in real property. REMICs are similar to CMOs 
in that they issue multiple classes of securities, but unlike CMOs, which are 
required to be structured as debt securities, REMICs may be structured as 
indirect ownership interests in the underlying assets of the REMICs 
themselves. However, there are no effects on the Fund from investing in CMOs 
issued by entities that have elected to be treated as REMICs, and all future 
references to CMOs shall also be deemed to include REMICs. The Fund may 
invest without limitation in CMOs. 

   In a CMO, a series of bonds or certificates is issued in multiple classes. 
Each class of CMOs, often referred to as a "tranche," is issued at a specific 
fixed or floating coupon rate and has a stated maturity or final distribution 
date. Principal prepayments on the Mortgage Assets may cause the CMOs to be 
retired substantially earlier than their stated maturities or final 
distribution dates. Interest is paid or accrues on all classes of the CMOs on 
a monthly, quarterly or semiannual basis. Certain CMOs may have variable or 
floating interest rates and others may be stripped (securities which provide 
only the principal or interest feature of the underlying security). 

   The principal of and interest on the Mortgage Assets may be allocated 
among the several classes of a CMO series in a number of different ways. 
Generally, the purpose of the allocation of the cash flow of a CMO to the 
various classes is to obtain a more predictable cash flow to the individual 
tranches than exists with the underlying collateral of the CMO. As a general 
rule, the more predictable the cash flow is on a CMO tranche, the lower the 
anticipated yield will be on that tranche at the time of issuance relative to 
prevailing market yields on Mortgage-Backed Securities. As part of the 
process of creating more predictable cash flows on most of the tranches in a 
series of CMOs, one or more tranches generally must be created that absorb 
most of the volatility in the cash flows on the underlying mortgage loans. 
The yields on these tranches, which may include inverse floaters and Stripped 
Mortgage-Backed Securities as described below, may be higher than prevailing 
market yields on Mortgage-Backed Securities with similar maturities. As a 
result of the uncertainty of the cash flows of these tranches, the market 
prices of and yield on these tranches generally are more volatile. 

   The Fund may invest up to 10% of its total assets in inverse floaters. 
Inverse floaters constitute a class of CMOs with a coupon rate that moves 
inversely to a designated index, such as the LIBOR (London Inter-Bank Offered 
Rate) Index. Inverse floaters have coupon rates that typically change at a 
multiple of the changes of the relevant index rate. Any rise in the index 
rate (as a consequence of an increase in interest rates) causes a drop in the 
coupon rate of an inverse floater while any drop in the index rate causes an 
increase in the coupon of an inverse floater. In addition, like most other 
fixed-income securities, the value of inverse floaters will decrease as 
interest rates increase. Inverse floaters exhibit greater price volatility 
than the majority of mortgage pass-through securities or CMOs. In addition, 
some inverse floaters exhibit extreme sensitivity to changes in prepayments. 
As a result, the yield to maturity of an inverse floater is sensitive not 
only to changes in interest rates but also to changes in prepayment rates on 
the related underlying Mortgage Assets. The Adviser believes that, 
notwithstanding the fact that inverse floaters exhibit price volatility, the 
use of inverse floaters as a component of the Fund's overall portfolio, in 
light of the Fund's anticipated portfolio composition in the aggregate, is 
compatible with the Fund's objective to earn a high level of current income 
while maintaining relatively low volatility of principal.

   The Fund also may invest in, among other things, parallel pay CMOs and 
Planned Amortization Class CMOs ("PAC Bonds"). Parallel pay CMOs are 
structured to provide payments of principal on each payment date to more than 
one class. These simultaneous payments are taken into account in calculating 
the stated maturity date or final distribution date of each class, which, as 
with other CMO structures, must be retired by its stated maturity date or 
final distribution date but may be retired earlier. PAC Bonds generally 
require payments of a specified amount of principal on each payment date. PAC 
Bonds always are parallel pay CMOs with the required principal payment on 
such securities having the highest priority after interest has been paid to 
all classes. 

   Stripped Mortgage-Backed Securities. Stripped Mortgage-Backed Securities 
are derivative multiclass mortgage securities. Stripped Mortgage-Backed 
Securities may be issued by agencies or instrumentalities of the United 
States Government, or by private originators of, or investors in, mortgage 
loans, including savings and loan associations, mortgage banks, commercial 
banks, investment banks and special purpose subsidiaries of the foregoing. 

   Stripped Mortgage-Backed Securities usually are structured with two 
classes that receive different proportions of the interest and principal 
distribution on a pool of Mortgage Assets. A common type of Stripped 
Mortgage-Backed Securities will have one class receiving some of the interest 
and most of the principal from the Mortgage Assets, while the other class 
will receive most of the interest and the remainder of the principal. In the 
most extreme case, one class will receive all of the interest (the 
interest-only or "IO" class), while the other class will receive all of the 
principal (the principal-only or "PO" class). PO classes generate income 
through the accretion of the deep discount at which such securities are 
purchased, and, while PO classes do not receive periodic payments of 
interest, they receive monthly payments associated with scheduled 
amortization and principal prepayment from the Mortgage Assets underlying the 
PO class. The yield to maturity on an IO class is extremely sensitive to the 
rate of principal payments (including prepayments) on the related underlying 
Mortgage Assets, and a rapid rate of principal payments may have a material 
adverse effect on the Fund's yield to maturity. If the underlying Mortgage 
Assets experience greater than anticipated prepayments of principal, the Fund 
may fail to fully recoup its initial investment in these securities even if 
the securities are rated Aaa by Moody's or AAA by S&P. 

   The Fund may purchase Stripped Mortgage-Backed Securities for income, or 
for hedging purposes to protect the Fund's portfolio against interest rate 
fluctuations. For example, since an IO class will tend to increase in value 
as interest rates rise, it may be utilized to hedge against a decrease in 
value of other fixed-income securities in a rising interest rate environment. 
The Fund's management understands that the staff of the Securities and 
Exchange Commission considers privately issued Stripped Mortgage-Backed 
Securities representing interest only or principal only components of U.S. 
Government or other debt securities to be illiquid securities. The Fund will 
treat such securities as illiquid so long as the staff maintains such 
position. Stripped Mortgage-Backed Securities issued by the U.S. Government 
or its agencies, and which are backed by fixed-rate mortgages, will be 
treated as liquid provided they are so determined by, or under procedures 
approved by, the Board of Trustees. The Fund may not invest more than 15% of 
its net assets in illiquid securities. 

CANADIAN MORTGAGE-BACKED SECURITIES 

   Canadian Mortgage-Backed Securities may be issued in several ways, the 
most common of which is a modified pass-through vehicle issued pursuant to 
the program established under the National Housing Act of Canada. 
Certificates issued pursuant to this program have some structural 
similarities to GNMA securities and benefit from the guarantee of the Canada 
Mortgage and Housing Corporation, a federal Crown corporation that is (except 
for certain limited purposes) an agent of the Government of Canada. 

   Canadian private issuers such as banks and trust companies also issue 
Mortgage-Backed Securities backed by private insurance or other forms of 
credit support. Such Mortgage-Backed Securities are not considered Government 
Securities for purposes of this Prospectus. 

                               12           
<PAGE>
   While most Canadian Mortgage-Backed Securities are subject to voluntary 
prepayments, some pools are not subject to such prepayments and thus have 
yield characteristics similar to bonds. 

   As the Canadian Mortgage-Backed Securities market was only recently 
established, it is less well developed and less liquid than its U.S. 
counterpart. 

RISK CONSIDERATIONS 

   The net asset value of the Fund's shares will fluctuate with changes in 
the market value of the Fund's portfolio securities. The market value of the 
Fund's portfolio securities will increase or decrease due to a variety of 
economic, market and political factors which cannot be predicted, in 
particular movements in interest rates and, with respect to foreign 
currencies, currency exchange rates. A decline in prevailing interest rates 
generally increases the value of fixed-income securities, while an increase 
in rates usually reduces the value of those securities. (The Fund's yield 
also will vary based on the yield of the Fund's portfolio securities.) 

   Mortgage-Backed Securities. Mortgage-Backed Securities have certain 
different characteristics than traditional debt securities. Among the major 
differences are that interest and principal payments are made more 
frequently, usually monthly, and that principal may be prepaid at any time 
because the underlying mortgage loans or other assets generally may be 
prepaid at any time. As a result, if the Fund purchases such a security at a 
premium, a prepayment rate that is faster than expected will reduce yield to 
maturity, while a prepayment rate that is slower than expected will have the 
opposite effect of increasing yield to maturity. Alternatively, if the Fund 
purchases these securities at a discount, faster than expected prepayments 
will increase, while slower than expected prepayments will reduce, yield to 
maturity. The Fund may invest a portion of its assets in derivative 
Mortgage-Backed Securities such as Stripped Mortgage-Backed Securities which 
are highly sensitive to changes in prepayment and interest rates. The Adviser 
seeks to manage these risks (and potential benefits) by investing in a 
variety of such securities. 

   Mortgage-Backed Securities, like all fixed income securities, generally 
decrease in value as a result of increases in interest rates. In addition, 
although generally the value of fixed-income securities increases during 
periods of falling interest rates and, as stated above, decreases during 
periods of rising interest rates, as a result of prepayments and other 
factors, this is not always the case with respect to Mortgage-Backed 
Securities. 

   Although the extent of prepayments on a pool of mortgage loans depends on 
various economic and other factors, as a general rule prepayments on fixed 
rate mortgage loans will increase during a period of falling interest rates 
and decrease during a period of rising interest rates. Accordingly, amounts 
available for reinvestment by the Fund are likely to be greater during a 
period of declining interest rates and, as a result, likely to be reinvested 
at lower interest rates than during a period of rising interest rates. 
Mortgage-Backed Securities generally decrease in value as a result of 
increases in interest rates and may benefit less than other fixed-income 
securities from declining interest rates because of the risk of prepayment. 

   The Fund may invest in mortgage derivative securities, such as CMOs, the 
average life of which is determined using mathematical models that 
incorporate prepayment assumptions and other factors that involve estimates 
of future economic and market conditions. These estimates may vary from 
actual future results, particularly during periods of extreme market 
volatility. In addition, under certain market conditions, such as those that 
developed in 1994, the average weighted life of mortgage derivative 
securities may not accurately reflect the price volatility of such 
securities. For example, in periods of supply and demand imbalances in the 
market for such securities and/or in periods of sharp interest rate 
movements, the prices of mortgage derivative securities may fluctuate to a 
greater extent than would be expected from interest rate movements alone. 

   The Fund's investments in mortgage derivative securities also subject the 
Fund to extension risk. Extension risk is the possibility that rising 
interest rates may cause prepayments to occur at a slower than 

                               13           
<PAGE>
expected rate. This particular risk may effectively change a security which 
was considered short or intermediate-term at the time of purchase into a 
long-term security. Long-term securities generally fluctuate more widely in 
response to changes in interest rates than short or intermediate-term 
securities. 

   There are certain risks associated specifically with CMOs. CMOs issued by 
private entities are not U.S. Government Securities and are not guaranteed by 
any government agency, although the securities underlying a CMO may be 
subject to a guarantee. Therefore, if the collateral securing the CMO, as 
well as any third party credit support or guarantees, is insufficient to make 
payment, the holder could sustain a loss. However, as stated above, the Fund 
will invest in CMOs issued by private entities only if the CMOs are rated at 
least AA by S&P or Aa by Moody's or, if unrated, are determined to be of 
comparable quality. Also, a number of different factors, including the extent 
of prepayment of principal of the Mortgage Assets, affect the availability of 
cash for principal payments by the CMO issuer on any payment date and, 
accordingly, affect the timing of principal payments on each CMO class. In 
addition, as stated above, inverse floaters, a class of CMOs in which the 
Fund may invest up to 10% of its net assets, exhibit greater price volatility 
than the majority of CMOs. 

CURRENCY RISKS 

   Investors should carefully consider the risks of investing in securities 
of foreign issuers and securities denominated in non-U.S. currencies. 
Fluctuations in the relative rates of exchange among the currencies of the 
United States, Canada and Mexico will affect the value of the Fund's 
investments. Changes in foreign currency exchange rates relative to the U.S. 
dollar will affect the U.S. dollar value of the Fund's assets denominated in 
that currency and thereby impact upon the Fund's total return on such assets. 

   Foreign currency exchange rates are determined by forces of supply and 
demand on the foreign exchange markets. These forces are themselves affected 
by the international balance of payments and other economic and financial 
conditions, government intervention, speculation and other factors. Moreover, 
foreign currency exchange rates may be affected by the regulatory control of 
the exchanges on which the currencies trade. 

RISKS OF INTERNATIONAL INVESTING 

   Investments in foreign securities will occasion risks relating to 
political and economic developments abroad, including the possibility of 
expropriations or confiscatory taxation, limitations on the use or transfer 
of Fund assets and any effects of foreign social, economic or political 
instability. Foreign securities are not subject to the regulatory 
requirements of U.S. securities and, as such, there may be less publicly 
available information about such securities. Moreover, issuers of foreign 
securities are not subject to uniform accounting, auditing and financial 
standards and requirements comparable to those applicable to issuers of U.S. 
securities. 

   Securities of foreign issuers may be less liquid than comparable 
securities of U.S. issuers and, as such, their price changes may be more 
volatile. Furthermore, foreign exchanges and broker-dealers are generally 
subject to less government and exchange scrutiny and regulation than their 
American counterparts. Brokerage commissions, dealer concessions and other 
transaction costs may be higher on foreign markets than in the U.S. In 
addition, differences in clearance and settlement procedures on foreign 
markets may occasion delays in settlements of Fund trades effected in such 
markets. Inability to dispose of portfolio securities due to settlement 
delays could result in losses to the Fund due to subsequent declines in value 
of such securities and the inability of the Fund to make intended security 
purchases due to settlement problems could result in a failure of the Fund to 
make potentially advantageous investments. 

   Canada. The Canadian debt securities market is significantly smaller than 
the U.S. debt securities market. In particular, the Canadian Mortgage-Backed 
Securities market is of recent origin, and, although continued growth is 
anticipated, is less well developed and less liquid than its U.S. 
counterpart. 

   Mexico. Because the Fund intends to invest in Mexican debt instruments, 
investors in the Fund 

                               14           
<PAGE>
should be aware of certain special considerations associated with investing 
in debt obligations of the Mexican government. 

   The Mexican government has exercised and continues to exercise a 
significant influence over many aspects of the private sector in Mexico. 
Mexican government actions concerning the economy could have a significant 
effect on market conditions and prices and yields of Mexican debt 
obligations, including those in which the Fund invests. Mexico is currently a 
major debtor nation (among developing countries) to commercial banks and 
foreign governments. 

   The value of the Fund's portfolio investments may be affected by changes 
in oil prices, interest rates, taxation and other political or economic 
developments in Mexico, including recent rates of inflation which have 
exceeded the rates of inflation in the U.S. and Canada. The Fund can provide 
no assurance that future developments in the Mexican economy will not impair 
its investment flexibility, operations or ability to achieve its investment 
objective. 

   In September, 1982, Mexico imposed foreign exchange controls and 
maintained a dual foreign exchange rate system, with a "controlled" rate and 
a "free market" rate. Under economic policy initiatives implemented since 
December, 1987, the Mexican government introduced a schedule of gradual 
devaluation of the controlled rate which initially amounted to an average 
depreciation of the Mexican peso against the U.S. dollar of one Mexican peso 
per day. The extended initiatives included an adjustment in the scheduled 
devaluation rate of the Mexican peso against the U.S. dollar. The Fund's net 
asset value and its computation and distribution of income to its 
shareholders will be adversely affected by continued reductions in the value 
of the Mexican peso relative to the U.S. dollar because all Fund assets must 
be converted to U.S. dollars prior to any distributions to shareholders. On 
December 22, 1994, the Mexican government determined to allow the Mexican 
peso to trade freely against the U.S. dollar rather than within a controlled 
band, which action resulted in a significant devaluation of the Mexican peso 
against the U.S. dollar. 

   Non-Diversified Status. The Fund is classified as a non-diversified 
investment company under the Investment Company Act of 1940, as amended (the 
"Act"), and as such is not limited by the Act in the proportion of its assets 
that it may invest in the obligations of a single issuer. However, the Fund 
intends to conduct its operations so as to qualify as a "regulated investment 
company" under Subchapter M of the Internal Revenue Code. See "Dividends, 
Distributions and Taxes." In order to qualify, among other requirements, the 
Fund will limit its investments so that at the close of each quarter of the 
taxable year, (i) not more than 25% of the market value of the Fund's total 
assets will be invested in the securities of a single issuer (other than U.S. 
Government Securities) and, (ii) with respect to 50% of the market value of 
its total assets not more than 5% will be invested in the securities of a 
single issuer (other than U.S. Government Securities) and the Fund will not 
own more than 10% of the outstanding voting securities of a single issuer. To 
the extent that a relatively high percentage of the Fund's assets may be 
invested in the obligations of a limited number of issuers, the Fund's 
portfolio securities may be more susceptible to any single economic, 
political or regulatory occurrence than the portfolio securities of a 
diversified investment company. The limitations described in this paragraph 
are not fundamental policies and may be revised to the extent applicable 
Federal income tax requirements are revised. 

   Debt securities which are issued or guaranteed by an agency or 
instrumentality of the United States, including certificates issued by GNMA, 
are treated like U.S. Government Securities for purposes of the 
diversification tests. However, securities issued or guaranteed by foreign 
governments, their political subdivisions, agencies and instrumentalities, 
including Canadian NHA Mortgage-Backed Securities, are not treated like U.S. 
Government Securities for purposes of the diversification tests described in 
the preceding paragraph, but instead are subject to these tests in the same 
manner as the securities of non-governmental issuers. In this regard, 
securities issued or guaranteed by a foreign government, its political 
subdivisions, agencies or instrumentalities may in certain circumstances be 
treated as issued by a single issuer for purposes of these diversification 
tests. Thus, in order to meet the diversification tests and thereby maintain 

                               15           
<PAGE>
its status as a regulated investment company, the Fund will be required to 
diversify its portfolio of Canadian Government Securities and Mexican 
Government Securities in a manner which would not be necessary if the Fund 
limited its investments to U.S. Government Securities. 

   
Year 2000.  The management services provided to the Fund by the Manager,
the investment advisory services provided to the Fund by the Adviser and
the services provided to shareholders by the Distributor and the Transfer
Agent depend on the smooth functioning of their computer systems. Many
computer software systems in use today cannot recognize the year 2000, but
revert to 1900 or some other date, due to the manner in which dates were
encoded and calculated. That failure could have a negative impact on the
handling of securities trades, pricing and account services. The Manager,
the Adviser, the Distributor and the Transfer Agent have been actively working
on necessary changes to their own computer systems to prepare for the year
2000 and expect that their systems will be adapted before that date, but
there can be no assurance that they will be successful, or that interaction
with other non-complying computer systems will not impair their services at 
that time.
    

   The risks of other investment techniques which may be utilized by the 
Fund, including options and futures transactions, are described under "Other 
Investment Policies," below. 

OTHER INVESTMENT POLICIES 

   Asset-Backed Securities. The Fund may invest in Asset-Backed Securities. 
Asset-Backed Securities represent the securitization techniques used to 
develop Mortgage-Backed Securities applied to a broad range of other assets. 
Through the use of trusts and special purpose corporations, various types of 
assets, primarily automobile and credit card receivables and home equity 
loans, are being securitized in pass-through structures similar to the 
mortgage pass-through structures described above or in a pay-through 
structure similar to the CMO structure. 

   Asset-Backed Securities involve certain risks that are not posed by 
Mortgage-Backed Securities, resulting mainly from the fact that Asset-Backed 
Securities do not usually contain the complete benefit of a security interest 
in the related collateral. For example, credit card receivables generally are 
unsecured and the debtors are entitled to the protection of a number of state 
and federal consumer credit laws, including the bankruptcy laws, some of 
which may reduce the ability to obtain full payment. In the case of 
automobile receivables, due to various legal and economic factors, proceeds 
for repossessed collateral may not always be sufficient to support payments 
on these securities. 

   New instruments and variations of existing Mortgage-Backed Securities and 
Asset-Backed Securities continue to be developed. The Fund, following 
revision to this Prospectus, may invest in any such instruments or variations 
as may be developed, to the extent consistent with its investment objective 
and policies and applicable regulatory requirements. 

   Repurchase Agreements. The Fund may enter into repurchase agreements, 
which may be viewed as a type of secured lending by the Fund, and which 
typically involve the acquisition by the Fund of debt securities, from a 
selling financial institution such as a bank, savings and loan association or 
broker-dealer. The agreement provides that the Fund will sell back to the 
institution, and that the institution will repurchase, the underlying 
security at a specified price and at a fixed time in the future, usually not 
more than seven days from the date of purchase. 

   While repurchase agreements involve certain risks not associated with 
direct investments in debt securities, 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 
Adviser subject to procedures established by the Board of Trustees of the 
Fund. In addition, the value of the collateral underlying the repurchase 
agreement will be at least equal to the repurchase price, including any 
accrued interest earned on the repurchase agreement. In the event of a 
default or 

                                   16

<PAGE>

bankruptcy by a selling financial institution, the Fund will seek 
to liquidate such collateral. However, the exercising of the Fund's right to 
liquidate such collateral could involve certain costs or delays and, to the 
extent that proceeds from any sale upon a default of the obligation to 
repurchase were less than the repurchase price, the Fund could suffer a loss. 
It is the current policy of the Fund not to invest in repurchase agreements 
that do not mature within seven days if any such investment, together with 
any other illiquid assets held by the Fund, amounts to more than 15% of its 
net assets. 

   Reverse Repurchase Agreements and Dollar Rolls. The Fund may also use 
reverse repurchase agreements and dollar rolls as part of its investment 
strategy. Reverse repurchase agreements involve sales by the Fund of 
portfolio assets concurrently with an agreement by the Fund to repurchase the 
same assets at a later date at a fixed price. The Fund may enter into dollar 
rolls in which the Fund sells securities for delivery in the current month 
and simultaneously contracts to repurchase substantially similar (same type 
and coupon) securities on a specified future date. Reverse repurchase 
agreements and dollar rolls involve the risk that the market value of the 
securities the Fund is obligated to repurchase under the agreement may decline 
below the repurchase price. In the event the buyer of securities under a 
reverse repurchase agreement or dollar roll files for bankruptcy or becomes 
insolvent, the Fund's use of proceeds of the agreement may be restricted 
pending a determination by the other party, or its trustee or receiver, 
whether to enforce the Fund's obligation to repurchase the securities. 

   Reverse repurchase agreements and dollar rolls are speculative techniques 
involving leverage, and are considered borrowings by the Fund. The Fund does 
not expect to engage in reverse repurchase agreements and dollar rolls with 
respect to greater than 25% of the Fund's total assets. 

   Private Placements. The Fund may invest up to 5% of its total assets in 
securities which are subject to restrictions on resale because they have not 
been registered under the Securities Act of 1933, as amended (the "Securities 
Act"), or which are otherwise not readily marketable. (Securities eligible 
for resale pursuant to Rule 144A under the Securities Act, and determined to 
be liquid pursuant to the procedures discussed in the following paragraph, 
are not subject to the foregoing restriction.) These securities are generally 
referred to as private placements or restricted securities. Limitations on 
the resale of such securities may have an adverse effect on their 
marketability, and may prevent the Fund from disposing of them promptly at 
reasonable prices. The Fund may have to bear the expense of registering such 
securities for resale and the risk of substantial delays in effecting such 
registration. 

   The Securities and Exchange Commission has adopted Rule 144A under the 
Securites Act, which permits the Fund to sell restricted securities to 
qualified institutional buyers without limitation. The Adviser, pursuant to 
procedures adopted by the Trustees of the Fund, will make a determination as 
to the liquidity of each restricted security purchased by the Fund. If a 
restricted security is determined to be "liquid," such security will not be 
included within the category "illiquid securities," which under current 
policy may not exceed 15% of the Funds net assets. However, investing in Rule 
144A securities could have the effect of increasing the level of Fund 
illiquidity to the extent that the Fund, at a particular point in time, may 
be unable to find qualified institutional buyers interested in purchasing 
such securities. 

   When-Issued and Delayed Delivery Securities and Forward Commitments. From 
time to time, in the ordinary course of business, the Fund may purchase 
securities on a when-issued or delayed delivery basis or may purchase or sell 
securities on a forward commitment basis. The securities so purchased or sold 
are subject to market fluctuation and no interest or dividends accrue to the 
purchaser prior to the settlement date. 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. 
At the time of delivery of the securities, the value may be more or less than 
the purchase or sale price. An increase in the percentage of the Fund's 
assets committed to the 

                                   17

<PAGE>

purchase of securities on a when issued, delayed delivery or forward 
commitment basis may increase the volatility of the Fund's net asset 
value. The Fund will establish a segregated account with its custodian 
bank in which it will maintain cash, U.S. Government securities or 
other liquid portfolio securities equal in value to its obligations in 
respect of when-issued or delayed delivery securities and forward 
commitments. The Fund's ability to enter into such transactions is not 
otherwise limited, but the Fund expects that under normal circumstances no 
more than 15% of the Fund's total assets will be so invested. 

   When, As and If Issued Securities. The Fund may purchase securities on a 
"when, as and if issued" basis under which the issuance of the security 
depends upon the occurrence of a subsequent event, such as approval of a 
merger, corporate reorganization, leveraged buyout or debt restructuring. If 
the anticipated event does not occur and the securities are not issued, the 
Fund will have lost an investment opportunity. An increase in the percentage 
of the Fund's assets committed to the purchase of securities on a "when, as 
and if issued" basis may increase the volatility of its net asset value. The 
Fund may also sell securities on a "when, as and if issued" basis provided 
that the issuance of the security will result automatically from the 
exchange or conversion of a security owned by the Fund at the time of sale. 

FORWARD FOREIGN CURRENCY EXCHANGE 
CONTRACTS 

   The Fund may engage in transactions in forward foreign currency exchange 
contracts. A forward foreign currency exchange contract ("forward contract") 
involves an obligation to purchase or sell a currency at a future date, which 
may be any fixed number of days from the date of the contract agreed upon by 
the parties, at a price set at the time of the contract. 

   Hedging against a decline in the value of a currency does not eliminate 
fluctuations in the prices of portfolio securities or prevent losses if the 
prices of such securities decline. Such transactions also limit the 
opportunity for gain if the value of the hedged currency should rise. 
Moreover, it may not be possible for the Fund to hedge against a devaluation 
that is so generally anticipated that the Fund is not able to contract to 
sell the currency at a price above the devaluation level it anticipates. 

   The Fund may enter into forward contracts under various circumstances. 
When the Fund enters into a contract for the purchase or sale of a security 
denominated in either the Canadian dollar or Mexican peso ("foreign 
currency"), it may, for example, desire to "lock in" the price of the 
security in U.S. dollars, Canadian dollars or Mexican pesos. At other times, 
when, for example, the Adviser believes that the Canadian dollar or the 
Mexican peso may suffer a substantial decline against the U.S. dollar, the 
Fund may enter into a forward contract to sell, for a fixed amount of dollars 
or pesos, the amount of foreign currency approximating the value of some or 
all of the Fund's portfolio securities (or securities which the Fund has 
purchased for its portfolio) denominated in such foreign currency. 

   If the Fund enters into forward contract transactions, and the currency in 
which the Fund's portfolio securities (or anticipated portfolio securities) 
are denominated rises in value with respect to the currency which is being 
purchased (or sold), then the Fund will have realized fewer gains than had 
the Fund not entered into the forward contracts. Moreover, the precise 
matching of the forward contract amounts and the value of the securities 
involved will not generally be possible, since the future value of such 
securities in foreign currencies will change as a consequence of market 
movements in the value of those securities between the date the forward 
contract is entered into and the date it matures. The Fund is not required to 
enter into such transactions with regard to its foreign currency-denominated 
securities and will not do so unless deemed appropriate by the Adviser. 
Currently, only a limited market exists for certain hedging transactions in 
future foreign exchange rates. This may limit the Fund's ability to 
effectively hedge its investments in Mexico. 

OPTIONS AND FUTURES TRANSACTIONS 

   The Fund may engage in transactions involving options on securities and 
currencies and futures contracts on securities, currencies and indexes, each 
as described below. 

                                   18

<PAGE>

   Options. The Fund may purchase and sell (write) call and put options on 
U.S. Treasury notes, bonds and bills and on the Canadian dollar or Mexican 
peso which are or may in the future be listed on several U.S. and foreign 
securities exchanges or are written in over-the-counter transactions ("OTC 
options"). Listed options are issued or guaranteed by the exchange on which 
they trade or by a clearing corporation such as the Options Clearing 
Corporation. OTC options are purchased from or sold (written) to dealers or 
financial institutions which have entered into direct agreements with the 
Fund. The Fund is permitted to write covered call options on portfolio 
securities and the U.S. dollar, the Canadian dollar and the Mexican peso, 
without limit, in order to aid it in achieving its investment objective. The 
Fund may also write covered put options; however, the aggregate value of the 
obligations underlying the puts determined as of the date the options are 
sold will not exceed 50% of the Fund's net assets. 

   The Fund may purchase listed and OTC call and put options in amounts 
equalling up to 5% of its total assets. The Fund may purchase call options to 
close out a covered call position or to protect against an increase in the 
price of a security it anticipates purchasing or, in the case of call options 
on a foreign currency, to hedge against an adverse exchange rate change of 
the currency in which the security it anticipates purchasing is denominated 
vis-a-vis the currency in which the exercise price is denominated. The Fund 
may purchase put options on securities which it holds in its portfolio only 
to protect itself against a decline in the value of the security. The Fund 
may also purchase put options to close out written put positions. There are 
no other limits on the Fund's ability to purchase call and put options. 

   Futures Contracts. The Fund may purchase and sell futures contracts that 
are currently traded, or may in the future be traded, on U.S. and foreign 
commodity exchanges on such underlying fixed-income securities as U.S. 
Treasury bonds, notes, and bills and/or any Canadian or Mexican government 
fixed-income security ("interest rate" futures), on the Canadian or Mexican 
currencies ("currency" futures) and on such indexes of U.S. or foreign 
fixed-income securities as may exist or come into being, such as the Moody's 
Investment Grade Corporate Bond Index ("index" futures). The Fund will 
purchase or sell interest rate futures contracts for the purpose of hedging 
some or all of the value of its portfolio securities (or anticipated 
portfolio securities) against changes in prevailing interest rates. The Fund 
will purchase or sell index futures contracts for the purpose of hedging some 
or all of its portfolio (or anticipated portfolio) securities against changes 
in their prices. 

   The Fund also may purchase and write call and put options on futures 
contracts which are traded on an exchange and enter into closing transactions 
with respect to such options to terminate an existing position. 

   New futures contracts, options and other financial products and various 
combinations thereof continue to be developed. The Fund may invest in any 
such futures, options or products as may be developed, to the extent 
consistent with its investment objective and applicable regulatory 
requirements. 

   Risks of Options and Futures Transactions. The Fund may close out its 
position as writer of an option, or as a buyer or seller of a futures 
contract, only if a liquid secondary market exists for options or futures 
contracts of that series. There is no assurance that such a market will 
exist, particularly in the case of OTC options, as such options may generally 
only be closed out by entering into a closing purchase transaction with the 
purchasing dealer. Also, exchanges may limit the amount by which the price of 
many futures contracts may move on any day. If the price moves equal the 
daily limit on successive days, then it may prove impossible to liquidate a 
futures position until the daily limit moves have ceased. 

   Participation in the options or futures markets involves investment risks 
and transaction costs to which the Fund would not be subject absent the use 
of these strategies. If the Adviser's prediction of movements in the 
direction of the securities, currency or interest rate markets are 
inaccurate, the adverse consequences to the Fund (e.g., a reduction in the 
Fund's net asset value or a reduction in the amount of income available for 
distribution) may leave the Fund in a 

                                   19

<PAGE>

worse position than if such strategies were not used. Risks inherent in the 
use of options, futures contracts and options on futures contracts include 
(a) dependence on the Adviser's ability to predict correctly movements in 
the direction of interest rates, as well as securities and/or currency 
markets; (b) imperfect correlation between the price of options and futures 
contracts and options thereon and movements in the prices of the securities 
or currencies being hedged; (c) the fact that skills needed to use these 
strategies are different from those needed to select portfolio securities; 
(d) the possible absence of a liquid secondary market for any particular 
instrument at any time; and (e) the possible need to defer closing out 
certain hedged positions to avoid adverse tax consequences. 

PORTFOLIO MANAGEMENT 

   The Fund's portfolio is actively managed by the Adviser with a view to 
achieving the Fund's investment objective. Philip A. Barach, James M. 
Goldberg, Jeffrey E. Gundlach and Frederick H. Horton, Managing Directors of 
the Adviser, are the Fund's primary portfolio managers, and, with the 
exception of Mr. Horton, have been so since the Fund's inception. Mr. Horton 
has been a primary portfolio manager since December, 1994. Messrs. Barach, 
Gundlach and Goldberg have each been portfolio managers with affiliates of 
TCW for over five years. Mr. Horton has been a portfolio manager with 
affiliates of TCW since October, 1993. From June 1991--September, 1993, he 
was Senior Portfolio Manager for Dewey Square Investors. 

   
   In determining which securities to purchase for the Fund or hold in the 
Fund's portfolio, the Adviser will rely on information from various sources, 
including research, analysis and appraisals of brokers and dealers, including 
Dean Witter Reynolds Inc. ("DWR"), Morgan Stanley & Co. Incorporated and 
other brokers and dealers that are affiliates of the Manager, and others 
regarding economic developments and interest rate trends; and the Adviser's 
own analysis of factors it deems relevant. 

   Brokerage commissions are not normally charged on the purchase or sale of 
U.S., Canadian or Mexican Government Securities, but such transactions 
generally involve costs in the form of spreads between bid and asked prices. 
Orders for transactions in portfolio securities are placed for the Fund with 
a number of brokers and dealers, which may include DWR, Morgan Stanley & Co. 
Incorporated and other brokers and dealers that are affiliates of the 
Manager. In addition, the Fund may incur brokerage commissions on 
transactions conducted through DWR, Morgan Stanley & Co. Incorporated and 
other brokers and dealers that are affiliates of the Manager. Under normal 
circumstances it is not anticipated that the portfolio trading will result in 
the Fund's portfolio turnover rate exceeding 100% in any one year. 
    

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

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

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

   The Fund may not: 

     1. Invest 25% or more of the value of its total assets in securities of 
    issuers in any one industry, except that the Fund will concentrate in 
    Mortgage-Backed Securities (unless it has adopted a temporary "defensive" 
    posture). This restriction does not apply to obligations issued or 
    guaranteed by the United States Government or its agencies or 
    instrumentalities. 

     2. Invest more than 5% of the value of its total assets in securities of 
    issuers having a record, together with predecessors, of less than three 
    years of continuous operation. This restriction 

                                   20

<PAGE>

    shall not apply to Mortgage-Backed Securities or Asset-Backed Securities 
    or to any obligation of the United States Government, its agencies or 
    instrumentalities. 

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

   In addition, as a non-fundamental policy, the Fund may not, as to 75% of 
its total assets, purchase more than 10% of the voting securities of any 
issuer. 

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

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 Manager, shares of 
the Fund are distributed by the Distributor and offered by DWR and others 
(which may include TCW Brokerage Services, an affiliate of the Adviser) which 
have entered into selected dealer agreements with the Distributor ("Selected 
Broker-Dealers"). The principal executive office of the Distributor is 
located at Two World Trade Center, New York, New York 10048. 

   
   The minimum initial purchase is $1,000 and subsequent purchases of $100 or 
more may be made by sending a check, payable to TCW/DW North American 
Government Income Trust, directly to Dean Witter Trust FSB (the "Transfer 
Agent") at P.O. Box 1040, Jersey City, NJ 07303, or by contacting an account 
executive of DWR or another Selected Broker-Dealer. 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. The minimum initial purchase in 
the case of an "Education IRA" is $500, if the Distributor has reason to 
believe that additional investments will increase the investment in the 
account to $1,000 within three years. In the case of investments pursuant to 
(i) Systematic Payroll Deduction Plans (including Individual Retirement 
Plans), (ii) the InterCapital mutual fund asset allocation program and (iii) 
fee-based programs approved by the Distributor, pursuant to which 
participants pay an asset based fee for services in the nature of investment 
advisory or administrative services, the Fund, in its discretion, may accept 
investments without regard to any minimum amounts which would otherwise be 
required, provided, in the case of Systematic Payroll Deduction Plans, that 
the Distributor has reason to believe that additional investments will 
increase the investment in all accounts under such Plans to at least $1,000. 
Certificates for shares purchased will not be issued unless a request is made 
by the shareholder in writing to the Transfer Agent. The offering price will 
be the net asset value per share next determined following receipt of an 
order (see "Determination of Net Asset Value" below). 
    

   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. Since DWR and other Selected Broker-Dealers forward investors' 
funds on settlement date, they may benefit from the temporary use of the 
funds where payment is made prior thereto. As noted above, orders placed 
directly with the Transfer Agent must be accompanied by payment. Investors 
will be entitled to receive dividends and capital gains distributions if 
their order is received by the close of business on the day prior to the 
record date for such distributions. 

   Sales personnel of a Selected Broker-Dealer are compensated for shares of 
the Fund sold by them by the Distributor or any of its affiliates and/or the 
Selected Broker-Dealer. In addition, some sales personnel of the Selected 
Broker-Dealer will receive 

                                   21

<PAGE>

various types of non-cash compensation as special sales incentives, including 
trips, educational and/or business seminars and merchandise. The Fund and the 
Distributor reserve the right to reject any purchase order. 

DETERMINATION OF NET ASSET VALUE 

   The net asset value per share of the Fund is determined once daily at 4:00 
p.m., New York time (or, on days when the New York Stock Exchange closes 
prior to 4:00 p.m., at such earlier time), on each day that the New York 
Stock Exchange is open by taking the value of all assets of the Fund, 
subtracting all its liabilities, dividing by the number of shares outstanding 
and adjusting to the nearest cent. The net asset value per share will not be 
determined on Good Friday and on such other federal and non-federal holidays 
as are observed by the New York Stock Exchange. 

   In the calculation of the Fund's net asset value: (1) an equity portfolio 
security listed or traded on the New York or American Stock Exchange or other 
stock exchange is valued at its latest sale price on that exchange; if there 
were no sales that day, the security is valued at the latest bid price (in 
cases where a security is traded on more than one exchange, the security is 
valued on the exchange designated as the primary market pursuant to 
procedures adopted by the Trustees); and (2) all other portfolio securities 
for which over-the-counter market quotations are readily available are valued 
at the latest bid price prior to the time of valuation. When market 
quotations are not readily available, including circumstances under which it 
is determined by the Adviser that sale or bid prices are not reflective of a 
security's market value, portfolio securities are valued at their fair value 
as determined in good faith under procedures established by and under the 
general supervision of the Fund's Trustees (valuation of securities for which 
market quotations are not readily available may also be based upon current 
market prices of securities which are comparable in coupon, rating and 
maturity or an appropriate matrix utilizing similar factors). For valuation 
purposes, quotations of foreign portfolio securities, other assets and 
liabilities and forward contracts stated in foreign currency are translated 
into U.S. dollar equivalents at the prevailing market rates prior to the 
close of the New York Stock Exchange. 

   Certain of the Fund's portfolio securities may be valued by an outside 
pricing service approved by the Fund's Trustees. The pricing service may 
utilize a matrix system incorporating security quality, maturity and coupon 
as the evaluation model parameters, and/or research and evaluations by its 
staff, including review of broker-dealer market price quotations, in 
determining what it believes is the fair valuation of the portfolio 
securities valued by such pricing service. 

   Short-term debt securities with remaining maturities of sixty days or less 
at the time of purchase are valued at amortized cost, unless the Trustees 
determine such does not reflect the securities' market value, in which case 
these securities will be valued at their fair value as determined by the 
Trustees. 

PLAN OF DISTRIBUTION 

   
   The Fund has entered into a Plan of Distribution pursuant to Rule 12b-1 
under the Act with the Distributor whereby the expenses of certain activities 
and services, including personal services to shareholders and maintenance of 
shareholder accounts, in connection with the distribution of the Fund's 
shares are reimbursed. The principal activities and services which may be 
provided by DWR, its affiliates or any other Selected Broker-Dealer under the 
Plan include: (1) compensation to, and expenses of, account executives and 
others, including overhead and telephone expenses; (2) sales incentives and 
bonuses to sales representatives and to marketing personnel in connection 
with promoting sales of the Fund's shares; (3) expenses incurred in 
connection with promoting sales of the Fund's shares; (4) preparing and 
distributing sales literature; and (5) providing advertising and promotional 
activities, including direct mail solicitation and television, radio, 
newspaper, magazine and other media advertisements. Reimbursements for these 
services will be made in monthly payments by the Fund, which will in no event 
exceed an amount equal to a payment at the annual rate of 0.75% of the Fund's 
average daily net assets. A portion of the amount payable pursuant to the 
Plan, which may not exceed 0.25% of the Fund's 

                                   22

<PAGE>

average daily net assets, is characterized as a service fee within NASD 
guidelines. The service fee is a payment made for personal service and/or the 
maintenance of shareholder accounts. Expenses incurred pursuant to the Plan 
in any fiscal year in excess of 0.75% of the Fund's average daily net assets 
will not be reimbursed by the Fund through payments accrued in any subsequent 
fiscal year. The Fund accrued $1,978,311 to the Distributor pursuant to the 
Plan for the fiscal year ended October 31, 1997. This is an accrual at the 
annual rate of 0.73% of the Fund's average daily net assets. 
    

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

   Automatic Investment of Dividends and Distributions. All income dividends 
and capital gains distributions are automatically paid in full and fractional 
shares of the Fund (or, if specified by the shareholder, any other open-end 
TCW/DW Fund), unless the shareholder requests that they be paid in cash. 

   Investment of Distributions Received in Cash. Any shareholder who receives 
a cash payment representing a dividend or capital gains distribution may 
invest such dividend or distribution at the net asset value next determined 
after receipt by the Transfer Agent by returning the check or the proceeds to 
the Transfer Agent within thirty days after the payment date. 

   
   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 or following 
redemption of shares of a Dean Witter money market fund, 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 "Repurchases and Redemptions -- 
Involuntary Redemption"). 
    

   Systematic Withdrawal Plan. A systematic withdrawal plan (the "Withdrawal 
Plan") is available for shareholders who own or purchase shares of the Fund 
having a minimum value of $10,000 based upon the then net asset value. The 
Withdrawal Plan provides for monthly or quarterly (March, June, September and 
December) checks in any dollar amount, not less than $25, or in any whole 
percentage of the account balance, on an annualized basis. Only shareholders 
having accounts in which no share certificates have been issued will be 
permitted to enroll in the Withdrawal Plan. 

   Shareholders should contact their DWR or other Selected Broker-Dealer 
account executive or the Transfer Agent for further information about any of 
the above services. 

   Tax Sheltered Retirement Plans. Retirement plans are available for use by 
the self-employed, eligible Individual Retirement Accounts and Custodial 
Accounts under Section 403(b)(7) of the Internal Revenue Code. Adoption of 
such plans should be on advice of legal counsel or tax adviser. 

   For further information regarding plan administration, custodial fees and 
other details, investors should contact their account executive or the 
Transfer Agent. 

EXCHANGE PRIVILEGE 

   
   An "Exchange Privilege," that is, the privilege of exchanging shares of 
certain Funds for shares of the Fund, exists whereby shares of TCW/DW Funds 
that are multiple class funds ("TCW/DW Multi-Class Funds") may be exchanged 
for shares of the Fund and for shares of five money market funds for which 
InterCapital serves as investment manager: Dean Witter Liquid Asset Fund 
Inc., Dean Witter U.S. Government Money Market Trust, Dean Witter Tax-Free 
Daily Income Trust, Dean Witter California Tax Free Daily Income Trust and 
Dean Witter New York Municipal Money Market Trust (the foregoing six funds, 
including the Fund, are hereinafter collectively referred to as "Exchange 
Funds"). Shares of the Exchange Funds received in an exchange for shares of a 
TCW/DW Multi-Class Fund may be redeemed and exchanged only for shares of the 
corresponding Class of a TCW/DW Multi-Class Fund or for shares of one of the 
other Exchange Funds. 

                                   23

<PAGE>

   An exchange to the Fund is on the basis of the next calculated net asset 
value per share of the Fund after the exchange order is received. When 
exchanging into a money market fund shares of the TCW/DW Multi-Class Fund are 
redeemed at their next calculated net asset value and exchanged for shares of 
the money market fund at their net asset value determined the following 
business day. Ultimately, any applicable contingent deferred sales charge 
("CDSC") will have to be paid upon redemption of shares originally purchased 
from a Class of a TCW/DW Multi-Class Fund that imposes a CDSC. During the 
period of time the shares originally purchased from a Class of a TCW/DW 
Multi-Class Fund that imposes a CDSC remain in the Exchange Fund, the holding 
period (for the purpose of determining the rate of CDSC) is frozen. If those 
shares are subsequently re-exchanged for shares of a TCW/DW Multi-Class Fund, 
the holding period previously frozen when the first exchange was made resumes 
on the last day of the month in which shares of a TCW/DW Multi-Class Fund are 
reacquired. Thus, the CDSC is based upon the time (calculated as described 
above) the shareholder was invested in shares of a TCW/DW Multi-Class Fund. In 
the case of shares exchanged into an Exchange Fund, upon a redemption of 
shares which results in a CDSC being imposed, a credit (not to exceed the 
amount of the CDSC) will be given in an amount equal to the Exchange Fund 
12b-1 distribution fees which are attributable to those shares (see "Purchase 
of Fund Shares--Plan of Distribution" in the respective Exchange Fund 
prospectus for a description of Exchange Fund 12b-1 distribution fees). 
Exchanges may be made after the shares of the fund acquired by purchase (not 
by exchange or dividend reinvestment) have been held for thirty days. There is 
no waiting period for exchanges of shares acquired by exchange or dividend 
reinvestment. 

   Additional Information Regarding Exchanges. Purchases and exchanges should 
be made for investment purposes only. A pattern of frequent exchanges may be 
deemed by the Manager to be abusive and contrary to the best interests of the 
Fund's other shareholders and, at the Manager's discretion, may be limited by 
the Fund's refusal to accept additional purchases and/or exchanges from the 
investor. Although the Fund does not have any specific definition of what 
constitutes a pattern of frequent exchanges, and will consider all relevant 
factors in determining whether a particular situation is abusive and contrary 
to the best interests of the Fund and its other shareholders, investors 
should be aware that the Fund, each of the other TCW/DW Funds and each of the 
money market funds may in their discretion limit or otherwise restrict the 
number of times this Exchange Privilege may be exercised by any investor. Any 
such restriction will be made by the Fund on a prospective basis only, upon 
notice to the shareholder not later than ten days following such 
shareholder's most recent exchange. Also, the Exchange Privilege may be 
terminated or revised at any time by the Fund and/or any other TCW/DW Funds 
or money market 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 pledged in the margin account. 

   The current prospectus for each fund describes its investment objective(s) 
and policies, and shareholders should obtain a copy and examine it carefully 
before investing. Exchanges are subject to the minimum investment requirement 
of each Class of shares and any other conditions imposed by each fund. In the 
case of any shareholder holding a share ceritificate or certificates, no 
exchanges may be made until all applicable share certificates have been 
received by the Transfer Agent and deposited in the shareholder's account. An 
exchange will be treated for federal income tax purposes the same as a 
repurchase or redemption of shares, on which the shareholder may realize a 
capital gain or loss. However, the ability to deduct capital losses on an 
exchange may be limited in situations where there is an exchange of shares 
within ninety days after the shares are purchased. The Exchange Privilege is 
only available in states where an exchange may legally be made. 
    

   If DWR or another Selected Broker-Dealer is the current dealer of record 
and its account numbers are 

                                   24

<PAGE>

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

   Telephone exchange instructions will be accepted if received by the 
Transfer Agent between 9:00 a.m. and 4:00 p.m. New York time, on any day the 
New York Stock Exchange is open. Any shareholder wishing to make an exchange 
who has previously filed an Exchange Privilege Authorization Form and who is 
unable to reach the Fund by telephone should contact his or her DWR or other 
Selected Broker-Dealer account executive, if appropriate, or make a written 
exchange request. Shareholders are advised that during periods of drastic 
economic or market changes it is possible that the telephone exchange 
procedures may be difficult to implement, although this has not been the 
experience in the past with other funds managed by the Manager. 

   Shareholders should contact their DWR or other Selected Broker-Dealer 
account executive or the Transfer Agent for further information about the 
Exchange Privilege. 

REPURCHASES AND REDEMPTIONS 
- ----------------------------------------------------------------------------- 

   Repurchases. DWR and other Selected Broker-Dealers are authorized to 
repurchase, as agent for the Fund, shares represented by a share certificate 
which is delivered to any of their offices. Shares held in a shareholder's 
account without a share certificate may also be repurchased by DWR and other 
Selected Broker-Dealers upon the telephonic request of the shareholder. The 
repurchase price is the net asset value next determined (see "Purchase of 
Fund Shares--Determination of Net Asset Value") after such repurchase order 
is received by DWR or the other Selected Broker-Dealer. 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 below under 
"Redemptions." 

   Redemptions. Shares of the Fund can be redeemed for cash at any time at 
net asset value per share next determined. If shares are held in a 
shareholder's account at the Transfer Agent without a share certificate, a 
written request for redemption must be sent to the Fund's Transfer Agent at 
P.O. Box 983, Jersey City, NJ 07303. 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 determined as described under "Purchase of Fund 
Shares--Determination of Net Asset Value" after it receives the request, and 
certificate, if any, in good order. Any redemption request received after 
such determination 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 

                                      25

<PAGE>

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. With regard 
to shares of the Fund acquired pursuant to the Exchange Privilege, any 
applicable contingent deferred sales charge will be imposed upon the 
redemption of such shares (see "Purchase of Fund Shares--Exchange Privilege"). 

   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 DWR or another 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 revised prospectus. 

   Payment for Shares Repurchased or Redeemed. Payment for shares presented 
for repurchase or redemption will be made by check within seven days after 
receipt by the Transfer Agent of the certificate and/or written request in 
good order. Such payment may be postponed or the right of redemption 
suspended under unusual circumstances. If the shares to be redeemed have 
recently been purchased by check, payment of the redemption proceeds may be 
delayed for the minimum time needed to verify that the check used for 
investment has been honored (not more than fifteen days from the time of 
receipt of the check by the Transfer Agent). Shareholders maintaining margin 
accounts with DWR or another Selected Broker-Dealer are referred to their 
account executive regarding restrictions on redemption of shares of the Fund 
pledged in the margin account. 

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

   Involuntary Redemption. The Fund reserves the right to redeem, on sixty 
days' notice and at net asset value, the shares of any shareholder (other 
than shares held in an Individual Retirement Account or Custodial Account 
under Section 403(b)(7) of the Internal Revenue Code) whose shares have a 
value of less than $100 as a result of redemptions or repurchases, or such 
lesser amount as may be fixed by the 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 60 days 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. 

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

   
   Dividends and Distributions. The Fund intends to pay monthly income 
dividends and to distribute net capital gains, if any, at least once each 
year. The Fund may, however, determine either to distribute or to retain all 
or part of any long-term capital gains in any year for reinvestment. 
    

   The Fund may, at times, make payments from sources other than net 
investment income, net realized short-term capital gains and net realized 
long-term capital gains. Payments from such sources would, in effect, 
represent a return of a portion of each 

                                   26

<PAGE>

shareholder's investment. All, or a portion, of such payments would not be 
taxable to shareholders. 

   
   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, for 
tax purposes, to have been received by the shareholder in the prior calendar 
year. 
    

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

   
   Taxes. Because the Fund intends to distribute all of its net investment 
income and net short-term capital gains to shareholders and otherwise remain 
qualified as a regulated investment company under Subchapter M of the Internal 
Revenue Code, it is not expected that the Fund will be required to pay any 
federal income tax on such income and capital gains. 
    

   Shareholders who are required to pay taxes on their income will normally 
have to pay federal income taxes, and any applicable state and/or local 
income taxes, on the dividends and distributions they receive from the Fund. 
Such dividends and distributions, to the extent that they are derived from 
net investment income and net short-term capital gains, are taxable to the 
shareholder as ordinary dividend income regardless of whether the shareholder 
receives such distributions in additional shares or in cash. Any dividends 
declared in the last quarter of any calendar year which are paid in the 
following calendar year prior to February 1, will be deemed, for tax 
purposes, to have been received by the shareholder in the prior calendar 
year. 

   Distributions of net long-term capital gains, if any, are taxable to 
shareholders as long-term capital gains regardless of how long a shareholder 
has held the Fund's shares and regardless of whether the distribution is 
received in additional shares or in cash. It is not anticipated that any 
portion of the Fund's distributions will be eligible for the dividends 
received deduction to corporate shareholders. 

   
   After the end of the calendar year, shareholders will be sent full 
information on their dividends and capital gains distributions for tax 
purposes. Shareholders will also be notified of their proportionate share of 
long-term capital gains distributions that are eligible for a reduced rate of 
tax under the Taxpayer Relief Act of 1997. 
    

   To avoid being subject to a 31% federal backup withholding tax on taxable 
dividends, capital gains distributions and the proceeds of redemptions and 
repurchases, shareholders' taxpayer identification numbers must be furnished 
and certified as to their accuracy. Shareholders who are not citizens or 
residents of, or entities organized in, the United States may be subject to 
withholding taxes of up to 30% on certain payments received from the Fund. 

   Dividends, interest and gains received by the Fund may give rise to 
withholding and other taxes imposed by foreign countries. If it qualifies for 
and has made the appropriate election with the Internal Revenue Service, the 
Fund will report annually to its shareholders the amount per share of such 
taxes, to enable shareholders to claim United States foreign tax credits or 
deductions with respect to such taxes. In the absence of such an election, 
the Fund would deduct foreign tax in computing the amount of its 
distributable income. 

   The foregoing discussion relates solely to the federal income tax 
consequences of an investment in the Fund. Distributions may also be subject 
to state and local taxes; therefore, each shareholder is advised to consult 
his or her own tax adviser. 

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

   From time to time the Fund may quote its "yield" and/or its "total return" 
in advertisements and sales literature. Both the yield and the total return 
of the Fund are based on historical earnings and yield of the Fund is 
computed by dividing the net investment income of the Fund over a 30-day 
period by an average value (using the average number of shares entitled to 
receive dividends and the net asset value 

                                   27

<PAGE>

per share at the end of the period), all in accordance with applicable 
regulatory requirements. Such amount is compounded for six months and then 
annualized for a twelve-month period to derive the yield of the Fund. 

   The "average annual total return" of the Fund refers to a figure 
reflecting the average annualized percentage increase (or decrease) in the 
value of an initial investment in the Fund of $1,000 over one, five and ten 
years or the life of the Fund, if less than any of the foregoing. Average 
annual total return reflects all income earned by the Fund, any appreciation 
or depreciation of the assets of the Fund, and all expenses incurred by the 
Fund, 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. The Fund may also advertise the growth 
of hypothetical investments of $10,000, $50,000 and $100,000 in shares of the 
Fund. The Fund from time to time may also advertise its performance relative 
to certain performance rankings and indexes compiled by independent 
organizations(such as mutual fund performance rankings of Lipper Analytical 
Services, Inc.). 

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

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

   The Fund is not required to hold Annual Meetings of Shareholders and, in 
ordinary circumstances, the Fund does not intend to hold such meetings. The 
Trustees may call Special Meetings of Shareholders for action by shareholder 
vote as may be required by the Act or the Declaration of Trust. Under certain 
circumstances, the Trustees may be removed by action of the Trustees or by 
the shareholders. 

   Under Massachusetts law, shareholders of a business trust may, under 
certain circumstances, be held personally liable as partners for the 
obligations of the Fund. However, the Declaration of Trust contains an 
express disclaimer of shareholder liability for acts or obligations of the 
Fund, requires that Fund obligations include such disclaimer, and provides 
indemnification and reimbursement of expenses out of the Fund's property for 
any shareholder held personally liable for the obligations of the Fund. Thus, 
the risk of a shareholder incurring financial loss on account of shareholder 
liability is limited to circumstances in which the Fund itself would be 
unable to meet its obligations. Given the above limitations on shareholder 
personal liability, and the nature of the Fund's assets and operations, the 
possibility of the Fund being unable to meet its obligations is remote and 
thus, in the opinion of Massachusetts counsel to the Fund, the risk to Fund 
shareholders of personal liability is remote. 

   Code of Ethics. The Adviser is subject to a Code of Ethics with respect to 
investment transactions in which the Adviser's officers, directors and 
certain other persons have a beneficial interest to avoid any actual or 
potential conflict or abuse of their fiduciary position. The Code of Ethics, 
as it pertains to the TCW/DW Funds, contains several restrictions and 
procedures designed to eliminate conflicts of interest including: (a) 
pre-clearance of personal investment transactions to ensure that personal 
transactions by employees are not being conducted at the same time as the 
Adviser's clients; (b) quarterly reporting of personal securities 
transactions; (c) a prohibition against personally acquiring securities in an 
initial public offering, entering into uncovered short sales and writing 
uncovered options; (d) a seven day "black-out period" prior or subsequent to 
a TCW/DW Fund transaction during which portfolio managers are prohibited from 
making certain transactions in securities which are being purchased or sold 
by a TCW/DW Fund; (e) a prohibition, with respect to certain investment 
personnel, from profiting in the purchase and 

                                   28

<PAGE>

sale, or sale and purchase, of the same (or equivalent) securities within 60 
calendar days; and (f) a prohibition against acquiring any security which is 
subject to firm wide or, if applicable, a department restriction of the 
Adviser. The Code of Ethics provides that exemptive relief may be given from 
certain of its requirements, upon application. The Adviser's Code of Ethics 
complies with regulatory requirements and, insofar as it relates to persons 
associated with registered investment companies, the 1994 Report of the 
Advisory Group on Personal Investing of the Investment Company Institute. 

   
   Litigation. Several class action lawsuits, which have been consolidated, 
were instituted in 1995 in the United States District Court, in New York, 
against the Fund, some of its Trustees and officers, its underwriter and 
distributor, the Adviser, the Manager, and other defendants, by certain 
shareholders of the Fund. The consolidated amended complaint asserts claims 
under the Securities Act of 1933 and generally alleges that the defendants 
made inadequate and misleading disclosures in the prospectuses for the Fund, 
in particular as such disclosures relate to the nature and risks of the Fund's 
investments in mortgage-backed securities and Mexican securities. The 
plaintiffs also challenge certain fees paid by the Fund as excessive. Damages 
are sought in an unspecified amount. All defendants moved to dismiss the 
consolidated amended complaint, and on May 8, 1996 the motions to dismiss 
were denied. The defendants moved for reargument and on August 28, 1996 the 
Court issued a second opinion which granted the motion to dismiss in part. On 
December 4, 1996, the defendants filed a renewed motion to dismiss which was 
denied by the Court on November 20, 1997. The Court has also certified a 
plaintiff class pursuant to the Federal Rules of Civil Procedure. The Adviser 
and the Manager believe that the litigation will not have a material adverse 
effect on their ability to perform under their respective agreements with the 
Fund or a material adverse effect on the Fund and its shareholders. 
    

   Shareholder Inquiries. All inquiries regarding the Fund should be directed 
to the Fund at the telephone numbers or address set forth on the front cover 
of this Prospectus.

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

THE FUND 

   The Fund is a trust of the type commonly known as a "Massachusetts 
business trust" and was organized under the laws of the Commonwealth of 
Massachusetts on February 19, 1992. The Fund is one of the TCW/DW Funds, 
which currently consist, in addition to the Fund, of TCW/DW Core Equity 
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 Mid-Cap Equity 
Trust, TCW/DW Global Telecom Trust, TCW/DW Strategic Income Trust, TCW/DW 
Term Trust 2002, TCW/DW Term Trust 2003, TCW/DW Term Trust 2000, TCW/DW 
Emerging Markets Opportunities Trust and TCW/DW Total Return Trust. 

THE MANAGER 

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

   Pursuant to a management agreement (the "Management Agreement") with the 
Manager, the Fund has retained the Manager to manage the Fund's business 
affairs, supervise the overall day-to-day operations of the Fund (other than 
rendering investment advice) and provide all administrative services to the 
Fund. Under the terms of the Management Agreement, the Manager also maintains 
certain of the Fund's books and records and furnishes, at its own expense, 
such office space, facilities, equipment, supplies, clerical help and 
bookkeeping and legal services as the Fund may reasonably require in the 
conduct of its business, including the preparation of prospectuses, 
statements of additional information, proxy statements and reports required 
to be filed with federal and state securities commissions (except insofar as 
the participation or assistance of independent accountants and attorneys is, 
in the opinion of the Manager, necessary or desirable). In addition, the 
Manager pays the salaries of all personnel, including officers of the Fund, 
who are employees of the Manager. The Manager also bears the cost of the 
Fund's telephone service, heat, light, power and other utilities. 

   
   As full compensation for the services and facilities furnished to the Fund 
and expenses of the Fund assumed by the Manager, the Fund pays the Manager 
monthly compensation calculated daily by applying the following annual rates 
to the Fund's daily net assets determined as of the close of each business 
day: 0.39% of the portion of daily net assets not exceeding $3 billion; and 
0.36% of the portion of daily net assets exceeding $3 billion. While the fee 
payable under the Management Agreement may be higher than that paid by other 
investment companies for similar services, the Board of Trustees determined 
that the total fees payable under the Management Agreement and the Advisory 
Agreement (as defined below) are reasonable in relation to the scope and 
quality of services to be provided thereunder. In this regard, in evaluating 
the Management Agreement, the Board of Trustees recognized that the Manager 
and the Adviser had, pursuant to an agreement described under the section 
entitled "The Adviser," agreed to a division as between themselves of the 
total fees necessary for the management of the business affairs of and the 
furnishing of investment advice to the Fund. Accordingly, in reviewing the 
Management Agreement and Advisory Agreement, the Board viewed as most 
significant the question as to whether the total fees payable under the 
Management and Advisory Agreements were in the aggregate reasonable in 
relation to the services to be provided thereunder. For the fiscal years 
ended October 31, 1995, 1996 and 1997, the Fund accrued to the Manager, total 
compensation of $3,166,169, $1,912,210 and $1,052,959, respectively. 
    

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

                                3           
<PAGE>
   InterCapital paid the organizational expenses of the Fund incurred prior 
to the offering of the Fund's shares. The Fund has reimbursed the Manager for 
$200,000 of such expenses, in accordance with the terms of the Underwriting 
Agreement between the Fund and DWR. The Fund has deferred and is amortizing 
the reimbursed expenses on the straight line method over a period not to 
exceed five years from the date of commencement of the Fund's operations. 

   The Management Agreement was initially approved by the Trustees on June 4, 
1994 and became effective on April 17, 1995. The Management Agreement 
replaced a prior management agreement in effect between the Fund and the 
Manager, which in turn had replaced a management agreement between the Fund 
and InterCapital, the parent company of the Manager. (That management 
agreement in turn had replaced, on June 30, 1993 upon the spin-off by Sears, 
Roebuck and Co. of its remaining shares of DWDC, an earlier substantially 
identical management agreement (originally with DWR, and assumed by 
InterCapital effective January, 1993) which was approved by the Trustees on 
October 30, 1992.) The nature and scope of services provided to the Fund, and 
the formula to determine fees paid by the Fund under the Management 
Agreement, are identical to those of the Fund's previous management 
agreements. The Management Agreement may be terminated at any time, without 
penalty, on thirty days' notice by the Trustees of the Fund. 

   Under its terms, the Management Agreement had an initial term ending April 
30, 1995, and will continue in effect from year to year thereafter, provided 
continuance of the Agreement is approved at least annually by the Trustees of 
the Fund, including the vote of a majority of the Independent Trustees who 
are not parties to the Management or Advisory Agreement or "interested 
persons" (as defined in the Investment Company Act of 1940, as amended (the 
"Act")) of any such party (the "Independent Trustees"). Continuation of the 
Management Agreement until April 30, 1997 was approved by the Trustees, 
including a majority of the Independent Trustees, at a meeting held on April 
17, 1996. 

THE ADVISER 

   
   TCW Funds Management, Inc. (the "Adviser"), a California corporation, is a 
wholly-owned subsidiary of The TCW Group, Inc. ("TCW"), whose subsidiaries, 
including Trust Company of the West and TCW Asset Management Company, provide 
a variety of trust, investment management and investment advisory services. 
As of December 31, 1997, the Adviser and its affiliates had approximately $50 
billion under management or committed to management. Trust Company of the 
West and its affiliates have managed securities portfolios for institutional 
investors since 1971. The Adviser is headquartered at 865 South Figueroa 
Street, Suite 1800, Los Angeles, California 90017 and is registered as an 
investment adviser under the Investment Advisers Act of 1940. In addition to 
the Fund, the Adviser currently serves as investment adviser to thirteen 
other TCW/DW Funds: TCW/DW Core Equity Trust, TCW/DW Latin American Growth 
Fund, TCW/DW Term Trust 2002, TCW/DW Income and Growth Fund, TCW/DW Term 
Trust 2003, TCW/DW Small Cap Growth Fund, TCW/DW Balanced Fund, TCW/DW Term 
Trust 2000, TCW/DW Emerging Markets Opportunities Trust, TCW/DW Mid-Cap 
Equity Trust, TCW/DW Global Telecom Trust, TCW/DW Total Return Trust and 
TCW/DW Strategic Income Trust. The Adviser also serves as investment adviser 
to TCW Convertible Securities Fund, Inc., a closed-end investment company 
listed on the New York Stock Exchange, and to The TCW Galileo Funds, Inc., an 
open-end investment company, and acts as adviser or sub-adviser to other 
investment companies. 
    

   Robert A. Day, who is Chairman of the Board of Directors of TCW, may be 
deemed to be a control person of the Adviser by virtue of the aggregate 
ownership of Mr. Day and his family of more than 25% of the outstanding 
voting stock of TCW. 

   Pursuant to an investment advisory agreement (the "Advisory Agreement") 
with the Adviser, the Fund has retained the Adviser to invest the Fund's 
assets, including the placing of orders for the purchase and sale of 
portfolio securities. The Adviser 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. In addition, the 
Adviser pays the salaries of all personnel, including officers of the Fund, 
who are employees of the Adviser. 

   As full compensation for the services and facilities furnished to the Fund 
and expenses of the Fund assumed by the Adviser, the Fund pays the Adviser 
monthly compensation calculated daily by applying the following annual rates 
to the Fund's daily net assets determined as of the close of each business 
day: 0.26% of the portion of daily 

                                4           
<PAGE>
   
net assets not exceeding $3 billion; and 0.24% of the portion of daily net 
assets exceeding $3 billion. For the fiscal years ended October 31, 1995, 
1996 and 1997, the Fund accrued to the Adviser total compensation under the 
Advisory Agreement of $2,110,779, $1,274,806 and $701,973, respectively. 
    

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

   The Advisory Agreement was initially approved by the Trustees on May 1, 
1992 and by DWR, as then sole shareholder, on May 11, 1992. The Advisory 
Agreement may be terminated at any time, without penalty, on thirty days' 
notice by the Trustees of the Fund, by the holders of a majority, as defined 
in the Act, of the outstanding shares of the Fund, or by the Adviser. The 
Agreement will automatically terminate in the event of its assignment (as 
defined in the Act). 

   
   Under its terms, the Advisory Agreement had an initial term ending April 
30, 1994, and provides that it will continue from year to year thereafter, 
provided continuance of the Agreement is approved at least annually by the 
vote of the holders of a majority, as defined in the Act, of the outstanding 
shares of the Fund, or by the Trustees of the Fund; provided that in either 
event such continuance is approved annually by the vote of a majority of the 
Independent Trustees of the Fund, which vote must be cast in person at a 
meeting called for the purpose of voting on such approval. Continuation of 
the Advisory Agreement until April 30, 1998 was approved by the Trustees, 
including a majority of the Independent Trustees, at a meeting called for 
that purpose on April 24, 1997. 

   Expenses not expressly assumed by the Manager under the Management 
Agreement, by the Adviser under the Advisory Agreement or by the Distributor 
of the Fund's shares Dean Witter Distributors Inc. ("Distributors" or the 
"Distributor") (see "The Distributor"), will be paid by the Fund. Such
expenses include, but are not limited to: expenses of the 
Plan of Distribution pursuant to Rule 12b-1 (see "The Distributor"); charges 
and expenses of any registrar; custodian, stock transfer and dividend 
disbursing agent; brokerage commissions and securities transaction costs;

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

   The Board of Trustees consists of nine (9) trustees. These same 
individuals also serve as trustees for all of the TCW/DW Funds. As of the 
date of this Statement of Additional Information, there are a total of 14 
TCW/DW Funds. As of December 31, 1997, the TCW/DW Funds had total net assets 
of approximately $4.4 billion and approximately a quarter of a million 
shareholders. 

   Five Trustees (56% of the total number) have no affiliation or business 
connection with TCW Funds Management, Inc. or Dean Witter Services Company 
Inc. or any of their affiliated persons and do not own any stock or other 
securities issued by MSDWD or TCW, the parent companies of Dean Witter 
Services Company Inc. and TCW Funds Management, Inc., respectively. These are 
the "disinterested" or "independent" Trustees. The other four Trustees (the 
"management Trustees") are affiliated with either Dean Witter Services 
Company Inc. or TCW. Four of the five independent Trustees are also 
Independent Trustees of the Dean Witter Funds. 

   Law and regulation establish both general guidelines and specific duties 
for the Independent Trustees. The TCW/DW 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, 1997, the three Committees held a combined total of sixteen meetings. The 
Committees hold some meetings at the offices of the Manager or Adviser and 
some outside those offices. 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. Each of the open-end TCW/DW Funds 
has such a plan. 

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

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

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

   The Chairman of the Committees maintains an office in 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 
    

                                9

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 Adviser and the 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 TCW/DW Funds and as Chairman of the Committee of the 
Independent Trustees and the Audit Committee and Independent Director or 
Trustee of the Dean Witter 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 TCW/DW 
FUNDS 

   The Independent Trustees and the Funds' management believe that having the 
same Independent Trustees for each of the TCW/DW 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 TCW/DW Funds. 

COMPENSATION OF INDEPENDENT TRUSTEES 

   The Fund pays each Independent Trustee an annual fee of $2,225 plus a per 
meeting fee of $200 for meetings of the Board of Trustees or committees of 
the Board of Trustees attended by the Trustee (the Fund pays the Chairman of 
the Audit Committee an annual fee of $750 and pays the Chairman of the 
Committee of the Independent Trustees an additional annual fee of $1,200). If 
a Board meeting and a Committee meeting, or more than one Committee meeting, 
take place on a single day, the Trustees are paid a single meeting fee by the 
Fund. 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 Manager or the Adviser or an affiliated company of either receive no 
compensation or expense reimbursement from the Fund. The Trustees of the 
TCW/DW Funds do not have retirement or deferred compensation plans.

   As of the date of this Statement of Additional Information, 57 of the Dean 
Witter Funds 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 

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

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

   Mexican Sovereign Debt. Sovereign Debt differs from debt obligations 
issued by private entities in that usually remedies from defaults must be 
pursued in the courts of the defaulting party. Legal recourse is therefore 
somewhat diminished. Political conditions, in terms of a country or agency's 
willingness to meet the terms of its debt obligations, is of considerable 
significance. Also, there can be no assurance that the holders of commercial 
bank debt may not contest payments to the holders of Sovereign Debt in the 
event of default under commercial bank loan agreements. 

   Sovereign Debt generally offers high yields, reflecting not only perceived 
credit risk, but also the need to compete with other local investments in 
domestic financial markets. Mexico is among the largest debtors to commercial 
banks and foreign governments. A foreign debtor's willingness or ability to 
repay principal and interest due in a timely manner may be affected by, among 
other factors, its cash flow situation, the extent of its foreign reserves, 
the availability of sufficient foreign exchange on the date a payment is due, 
the relative size of the debt service burden to the economy as a whole, the 
foreign debtor's policy towards the International Monetary Fund and the 
political constraints to which a sovereign debtor may be subject. Mexico may 
also be dependent on expected disbursements from foreign governments, 
multilateral agencies and others abroad to reduce principal and interest 
arrearages on their debt. The commitment on the part of these governments 
agencies and others to make such disbursements may be conditioned on its 
implementation of economic reforms and/or economic performance and the timely 
service of its obligations. Failure to implement such reforms, achieve such 
levels of economic performance or repay principal or interest when due, may 
result in the cancellation of such third parties' commitments to lend funds 
to Mexico, which may further impair its ability or willingness to service its 
debts. 

   The ability of the Mexican government to make timely payments on its 
Sovereign Debt is likely to be influenced strongly by its balance of trade 
and its access to trade and other international credits. In addition, the 
occurrence of political, social or diplomatic changes could adversely affect 
the Fund's investments. Mexico is faced with social and political issues and 
has experienced high rates of inflation in recent years. Among other effects, 
high inflation and internal debt service requirements may adversely affect 
the cost and availability of future domestic sovereign borrowing to finance 
governmental programs, and may have other adverse social, political and 
economic 

                               12           
<PAGE>
consequences. Political changes or a deterioration of Mexico's domestic 
economy or balance of trade may affect its willingness to service its 
Sovereign Debt. While the Adviser intends to invest the Fund's portfolio in a 
manner that will minimize the exposure to the risks of Sovereign Debt 
(specifically by limiting the Fund's investments to investment grade 
securities with maturities of one year or less), there can be no assurance 
that adverse political changes will not cause the Fund to suffer a loss of 
all or a portion of interest and/or principal on any of its holdings. 

MONEY MARKET SECURITIES 

   As stated in the Prospectus, the money market instruments which the Fund 
may purchase include U.S. Government securities, bank obligations, Eurodollar 
certificates of deposit, obligations of savings institutions, fully insured 
certificates of deposit and commercial paper. Such securities include: 

   U.S. Government Securities. Obligations issued or guaranteed as to 
principal and interest by the United States or its agencies (such as the 
Export-Import Bank of the United States, Federal Housing Administration and 
Government National Mortgage Association) or its instrumentalities (such as 
the Federal Home Loan Bank), including Treasury bills, notes and bonds; 

   Bank Obligations. Obligations (including certificates of deposit, bankers' 
acceptances, commercial paper (see below) and other debt obligations) of 
banks subject to regulation by the U.S. Government and having total assets of 
$1 billion or more, and instruments secured by such obligations, not 
including obligations of foreign branches of domestic banks except as 
permitted below; 

   Eurodollar Certificates of Deposit. Eurodollar certificates of deposit 
issued by foreign branches of domestic banks having total assets of $1 
billion or more (investments in Eurodollar certificates may be affected by 
changes in currency rates or exchange control regulations, or changes in 
governmental administration or economic or monetary policy in the United 
States and abroad); 

   Obligations of Savings Institutions. Certificates of deposit of savings 
banks and savings and loan associations, having total assets of $1 billion or 
more (investments in savings institutions above $100,000 in principal amount 
are not protected by federal deposit insurance); 

   Fully Insured Certificates of Deposit. Certificates of deposit of banks 
and savings institutions, having total assets of less than $1 billion, if the 
principal amount of the obligation is insured by the Bank Insurance Fund or 
the Savings Association Insurance Fund (each of which is administered by the 
Federal Deposit Insurance Corporation), limited to $100,000 principal amount 
per certificate and to 15% or less of the Fund's total assets in all such 
obligations and in all illiquid assets, in the aggregate; 

   
   Commercial Paper. Commercial paper rated within the two highest grades by 
Standard & Poor's Corporation or Moody's Investors Service, Inc. or, if not 
rated, issued by a company having an outstanding debt issue rated at least 
AAA by Standard & Poor's or Aaa by Moody's. 
    

MORTGAGE-BACKED SECURITIES 

   As stated in the Prospectus, the Fund may invest a portion of its assets 
in securities that directly or indirectly represent a participation in, or 
are secured by and payable from, mortgage loans secured by real property 
("Mortgage-Backed Securities"). The Fund will invest in mortgage pass-through 
securities representing participation interests in pools of residential 
mortgage loans originated by United States governmental or private lenders 
and guaranteed, to the extent provided in such securities, by the United 
States Government or one of its agencies or instrumentalities. Such 
securities, which are ownership interests in the underlying mortgage loans, 
differ from conventional debt securities, which provide for periodic payment 
of interest in fixed amounts (usually semi-annually) and principal payments 
at maturity or on specified call dates. Mortgage pass-through securities 
provide for monthly payments that are a "pass-through" of the monthly 
interest and principal payments (including any prepayments) made by the 
individual borrowers on the pooled mortgage loans, net of any fees paid to 
the guarantor of such securities and the servicer of the underlying mortgage 
loans. 

   Certificates for Mortgage-Backed Securities evidence an interest in a 
specific pool of mortgages. These certificates are, in most cases, "modified 
pass-through" instruments, wherein the issuing agency guarantees the payment 
of principal and interest on mortgages underlying the certificates, whether 
or not such amounts are collected by the issuer on the underlying mortgages. 

                               13           
<PAGE>
   Private Mortgage Pass-Through Securities. Private mortgage pass-through 
securities are issued by originators of and investors in mortgage loans, 
including savings and loan associations, mortgage banks, commercial banks, 
investment banks and special purpose subsidiaries of the foregoing. These 
securities usually are backed by a pool of conventional fixed rate or 
adjustable rate mortgage loans. Since private mortgage pass-through 
securities typically are not guaranteed by a governmental entity, such 
securities generally are structured with one or more types of credit 
enhancement. 

   Adjustable Rate Mortgage Securities. As stated in the Prospectus, the Fund 
may also invest in adjustable rate mortgage securities ("ARMs"), which are 
pass-through mortgage securities collateralized by mortgages with adjustable 
rather than fixed rates. ARMs eligible for inclusion in a mortgage pool 
generally provide for a fixed initial mortgage interest rate for either the 
first three, six, twelve or thirteen, twenty-four, thirty-six or longer 
scheduled monthly payments. Thereafter, the interest rates are subject to 
periodic adjustment based on changes to a designated benchmark index. 

   ARMs contain maximum and minimum rates beyond which the mortgage interest 
rate may not vary over the lifetime of the security. In addition, certain 
ARMs provide for additional limitations on the maximum amount by which the 
mortgage interest rate may adjust for any single adjustment period. 
Alternatively, certain ARMs contain limitations on changes in the required 
monthly payment. In the event that a monthly payment is not sufficient to pay 
the interest accruing on an ARM, any such excess interest is added to the 
principal balance of the mortgage loan, which is repaid through future 
monthly payments. If the monthly payment for such an instrument exceeds the 
sum of the interest accrued at the applicable mortgage interest rate and the 
principal payment required at such point to amortize the outstanding 
principal balance over the remaining term of the loan, the excess is utilized 
to reduce the then outstanding principal balance of the ARM. 

   Types of Credit Enhancement. Mortgage-Backed Securities are often backed 
by a pool of assets representing the obligations of a number of different 
parties. To lessen the effect of failures by obligors on underlying assets to 
make payments, those securities may contain elements of credit support, which 
fall into two categories: (i) liquidity protection and (ii) protection 
against losses resulting from ultimate default by an obligor on the 
underlying assets. Liquidity protection refers to the provision of advances, 
generally by the entity administering the pool of assets, to ensure that the 
receipt of payments on the underlying pool occurs in a timely fashion. 
Protection against losses resulting from default ensures ultimate payment of 
the obligations on at least a portion of the assets in the pool. This 
protection may be provided through guarantees, insurance policies or letters 
of credit obtained by the issuer or sponsor from third parties, through 
various means of structuring the transaction or through a combination of such 
approaches. The degree of credit support provided for each issue is generally 
based on historical information regarding the level of credit risk associated 
with the underlying assets. Delinquencies or losses in excess of those 
anticipated could adversely affect the return on an investment in a security. 
In addition, any circumstance adversely affecting the ability of third 
parties, such as insurance companies, to satisfy any of their obligations 
with respect to any Mortgage-Backed Securities, such as a diminishment of 
their creditworthiness, could affect the rating, and thus the value, of the 
securities. The Fund will not pay any fees for credit support, although the 
existence of credit support may increase the price of a security. 

FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS 

   As discussed in the Prospectus, the Fund may enter into forward foreign 
currency exchange contracts ("forward contracts") as a hedge against 
fluctuations in future foreign exchange rates. The Fund will conduct its 
foreign currency exchange transactions either on a spot (i.e., cash) basis at 
the spot rate prevailing in the foreign currency exchange market, or through 
entering into forward contracts to purchase or sell foreign currencies. A 
forward contract involves an obligation to purchase or sell a specific 
currency at a future date, which may be any fixed number of days from the 
date of the contract agreed upon by the parties, at a price set at the time 
of the contract. These contracts are traded in the interbank market conducted 
directly between currency traders (usually large commercial and investment 
banks) and their customers. Such forward contracts will only be entered into 
with United States banks and their foreign branches or foreign banks whose 
assets total $1 billion or more. A forward contract generally has no deposit 
requirement, and no commissions are charged at any stage for trades. 

   The Fund will enter into forward contracts under various circumstances. 
When the Fund enters into a contract for the purchase or sale of a security 
denominated in either the Canadian dollar or Mexican peso ("foreign 
currency"), it may, for example, desire to "lock in" the price of the 
security in U.S. dollars, Canadian dollars or 

                               14           
<PAGE>
Mexican pesos. By entering into a forward contract for the purchase or sale, 
for a fixed amount of dollars or other currency, of the amount of foreign 
currency involved in the underlying security transactions, the Fund will be 
able to protect itself against a possible loss resulting from an adverse 
change in the relationship between the U.S. dollar or other currency which is 
being used for the security purchase and the foreign currency in which the 
security is denominated during the period between the date on which the 
security is purchased or sold and the date on which payment is made or 
received. 

   At other times, when, for example, the Adviser believes that the Canadian 
dollar or Mexican peso may suffer a substantial decline against the U.S. 
dollar or some other foreign currency, the Fund may enter into a forward 
contract to sell, for a fixed amount of U.S. dollars, the amount of that 
currency approximating the value of some or all of the Fund's portfolio 
securities (or securities which the Fund has purchased for its portfolio) 
denominated in such foreign currency. 

   In addition, when the Adviser anticipates purchasing securities at some 
time in the future, and wishes to lock in the current exchange rate of the 
currency in which those securities are denominated against the U.S. dollar, 
the Fund may enter into a forward contract to purchase an amount of currency 
equal to some or all of the value of the anticipated purchase, for a fixed 
amount of U.S. dollars. 

   Finally, the Fund is permitted to enter into forward contracts with 
respect to currencies in which certain of its portfolio securities are 
denominated and on which options have been written (see "Options and Futures 
Transactions," below). 

   
   The Fund will not enter into such forward contracts or maintain a net 
exposure to such contracts where the consummation of the contracts would 
obligate the Fund to deliver an amount of Canadian dollars or Mexican pesos 
in excess of the value of the Fund's portfolio securities or other assets 
denominated in that currency. The Fund's custodian bank will place cash, U.S. 
Government securities or other appropriate liquid portfolio securities in a 
segregated account of the Fund in an amount equal to the value of the Fund's 
total assets committed to the consummation of forward contracts entered into 
under the circumstances set forth above. If the value of the securities 
placed in the segregated account declines, additional cash or securities will 
be placed in the account on a daily basis so that the value of the account 
will equal the amount of the Fund's commitments with respect to such 
contracts. 
    

   Where, for example, the Fund is hedging a portfolio position consisting of 
foreign fixed-income securities denominated in the Canadian dollar or Mexican 
peso against adverse exchange rate moves vis-a-vis the U.S. dollar, at the 
maturity of the forward contract for delivery by the Fund of the Canadian 
dollar or Mexican peso, the Fund may either sell the portfolio security and 
make delivery of the foreign currency, or it may retain the security and 
terminate its contractual obligation to deliver the Canadian dollar or 
Mexican peso by purchasing an "offsetting" contract with the same currency 
trader obligating it to purchase, on the same maturity date, the same amount 
of the Canadian dollar or Mexican peso. It is impossible to forecast the 
market value of portfolio securities at the expiration of the contract. 
Accordingly, it may be necessary for the Fund to purchase additional Canadian 
dollars or Mexican pesos on the spot market (and bear the expense of such 
purchase) if the market value of the security is less than the amount of 
foreign currency the Fund is obligated to deliver and if a decision is made 
to sell the security and make delivery of the Canadian dollars or Mexican 
pesos. Conversely, it may be necessary to sell on the spot market some of the 
Canadian dollars or Mexican pesos received upon the sale of the portfolio 
securities if its market value exceeds the amount of Canadian dollars or 
Mexican pesos the Fund is obligated to deliver. 

   If the Fund retains the portfolio securities and engages in an offsetting 
transaction, the Fund will incur a gain or loss to the extent that there has 
been movement in spot or forward contract prices. If the Fund engages in an 
offsetting transaction, it may subsequently enter into a new forward contract 
to sell the foreign currency. Should forward prices decline during the period 
between the Fund's entering into a forward contract for the sale of Canadian 
dollars or Mexican pesos and the date it enters into an offsetting contract 
for the purchase of the foreign currency, the Fund will realize a gain to the 
extent the price of the currency it has agreed to sell exceeds the price of 
the currency it has agreed to purchase. Should forward prices increase, the 
Fund will suffer a loss to the extent the price of the currency it has agreed 
to purchase exceeds the price of the currency it has agreed to sell. 

   If the Fund purchases a fixed-income security which is denominated in U.S. 
dollars but which will pay out its principal based upon a formula tied to the 
exchange rate between the U.S. dollar and the Canadian dollar or Mexican 
peso, it may hedge against a decline in the principal value of the security 
by entering into a forward contract to sell or purchase an amount of the 
relevant foreign currency equal to some or all of the principal value of the 
security. 

                               15           
<PAGE>
   At times when the Fund has written a call or put option on a fixed-income 
security or the currency in which it is denominated, it may wish to enter 
into a forward contract to purchase or sell the foreign currency in which the 
security is denominated. A forward contract would, for example, hedge the 
risk of the security on which a call currency option has been written 
declining in value to a greater extent than the value of the premium received 
for the option. The Fund will maintain with its Custodian at all times, cash, 
U.S. Government securities or other appropriate liquid portfolio securities 
in a segregated account equal in value to all forward contract obligations 
and option contract obligations entered into in hedge situations such as 
this. 

   Although the Fund values its assets daily in terms of U.S. dollars, it 
does not intend to convert its holdings of Canadian dollars and Mexican pesos 
into U.S. dollars on a daily basis. It will, however, do so from time to 
time, and investors should be aware of the costs of currency conversion. 
Although foreign exchange dealers do not charge a fee for conversion, they do 
realize a profit based on the spread between the prices at which they are 
buying and selling various currencies. Thus, a dealer may offer to sell a 
foreign currency to the Fund at one rate, while offering a lesser rate of 
exchange should the Fund desire to resell that currency to the dealer. 

   The Fund generally will not enter into a forward contract with a term of 
greater than one year, although it may enter into forward contracts for 
periods of up to five years. The Fund may be limited in its ability to enter 
into hedging transactions involving forward contracts by the Internal Revenue 
Code requirements relating to qualifications as a regulated investment 
company (see "Dividends, Distributions and Taxes"). 

OPTIONS AND FUTURES TRANSACTIONS 

   As discussed in the Prospectus, the Fund may write covered call options 
against securities held in its portfolio and covered put options on eligible 
portfolio securities and purchase options of the same series to effect 
closing transactions, and may hedge against potential changes in the market 
value of its investments (or anticipated investments) by purchasing put and 
call options on portfolio (or eligible portfolio) securities (and the 
currencies in which they are denominated) and engaging in transactions 
involving futures contracts and options on such contracts. 

   Call and put options on U.S. Treasury notes, bonds and bills and on 
various foreign currencies are listed on several U.S. and foreign securities 
exchanges and are written in over-the-counter transactions ("OTC Options"). 
Listed options are issued or guaranteed by the exchange on which they trade 
or by a clearing corporation such as the Options Clearing Corporation 
("OCC"). Ownership of a listed call option gives the Fund the right to buy 
from the OCC (in the U.S.) or other clearing corporation or exchange, the 
underlying security or currency covered by the option at the stated exercise 
price (the price per unit of the underlying security or currency) by filing 
an exercise notice prior to the expiration date of the option. The writer 
(seller) of the option would then have the obligation to sell, to the OCC (in 
the U.S.) or other clearing corporation or exchange, the underlying security 
or currency at that exercise price prior to the expiration date of the 
option, regardless of its then current market price. Ownership of a listed 
put option would give the Fund the right to sell the underlying security or 
currency to the OCC (in the U.S.) or other clearing corporation or exchange 
at the stated exercise price. Upon notice of exercise of the put option, the 
writer of the option would have the obligation to purchase the underlying 
security or currency from the OCC (in the U.S.) or other clearing corporation 
or exchange at the exercise price. 

   Options on Treasury Bonds and Notes. Because trading interest in options 
written on Treasury bonds and notes tends to center on the most recently 
auctioned issues, the exchanges on which such securities trade will not 
continue indefinitely to introduce options with new expirations to replace 
expiring options on particular issues. Instead, the expirations introduced at 
the commencement of options trading on a particular issue will be allowed to 
run their course, with the possible addition of a limited number of new 
expirations as the original ones expire. Options trading on each issue of 
bonds or notes will thus be phased out as new options are listed on more 
recent issues, and options representing a full range of expirations will not 
ordinarily be available for every issue on which options are traded. 

   Options on Treasury Bills. Because a deliverable Treasury bill changes 
from week to week, writers of Treasury bill calls cannot provide in advance 
for their potential exercise settlement obligations by acquiring and holding 
the underlying security. However, if the Fund holds a long position in 
Treasury bills with a principal amount of the 

                               16           
<PAGE>
securities deliverable upon exercise of the option, the position may be 
hedged from a risk standpoint by the writing of a call option. For so long as 
the call option is outstanding, the Fund will hold the Treasury bills in a 
segregated account with its Custodian, so that they will be treated as being 
covered. 

   Options on GNMA Certificates. Currently, options on GNMA Certificates are 
only traded over-the-counter. Since the remaining principal balance of GNMA 
Certificates declines each month as a result of mortgage payments, the Fund, 
as a writer of a GNMA call holding GNMA Certificates as "cover" to satisfy 
its delivery obligation in the event of exercise, may find that the GNMA 
Certificates it holds no longer have a sufficient remaining principal balance 
for this purpose. Should this occur, the Fund will purchase additional GNMA 
Certificates from the same pool (if obtainable) or replacement GNMA 
Certificates in the cash market in order to maintain its cover. A GNMA 
Certificate held by the Fund to cover an option position in any but the 
nearest expiration month may cease to represent cover for the option in the 
event of a decline in the GNMA coupon rate at which new pools are originated 
under the FHA/VA loan ceiling in effect at any given time, as such decline 
may increase the prepayments made on other mortgage pools. If this should 
occur, the Fund will no longer be covered, and the Fund will either enter 
into a closing purchase transaction or replace such Certificate with a 
Certificate which represents cover. When the Fund closes out its position or 
replaces such Certificate, it may realize an unanticipated loss and incur 
transaction costs. 

   Options on Foreign Currencies. The Fund may purchase and write options on 
foreign currencies for purposes similar to those involved with investing in 
forward foreign currency exchange contracts. For example, in order to protect 
against declines in the dollar value of portfolio securities which are 
denominated in a foreign currency, the Fund may purchase put options on an 
amount of such foreign currency equivalent to the current value of the 
portfolio securities involved. As a result, the Fund would be enabled to sell 
the foreign currency for a fixed amount of U.S. dollars, thereby "locking in" 
the dollar value of the portfolio securities (less the amount of the premiums 
paid for the options). Conversely, the Fund may purchase call options on 
foreign currencies in which securities it anticipates purchasing are 
denominated to secure a set U.S. dollar price for such securities and protect 
against a decline in the value of the U.S. dollar against such foreign 
currency. The Fund may also purchase call and put options to close out 
written option positions. 

   The Fund may also write call options on foreign currency to protect 
against potential declines in its portfolio securities which are denominated 
in foreign currencies. If the U.S. dollar value of the portfolio securities 
falls as a result of a decline in the exchange rate between the foreign 
currency in which it is denominated and the U.S. dollar, then a loss to the 
Fund occasioned by such value decline would be ameliorated by receipt of the 
premium on the option sold. At the same time, however, the Fund gives up the 
benefit of any rise in value of the relevant portfolio securities above the 
exercise price of the option and, in fact, only receives a benefit from the 
writing of the option to the extent that the value of the portfolio 
securities falls below the price of the premium received. The Fund may also 
write options to close out long call option positions. A put option on a 
foreign currency would be written by the Fund for the same reason it would 
purchase a call option, namely, to hedge against an increase in the U.S. 
dollar value of a foreign security which the Fund anticipates purchasing. 
Here, the receipt of the premium would offset, to the extent of the size of 
the premium, any increased cost to the Fund resulting from an increase in the 
U.S. dollar value of the foreign security. However, the Fund could not 
benefit from any decline in the cost of the foreign security which is greater 
than the price of the premium received. The Fund may also write options to 
close out long put and call option positions. 

   The markets in foreign currency options are relatively new and the Fund's 
ability to establish and close out positions on such options is subject to 
the maintenance of a liquid secondary market. Although the Fund will not 
purchase or write such options unless and until, in the opinion of the 
Adviser, the market for them has developed sufficiently to ensure that the 
risks in connection with such options are not greater than the risks in 
connection with the underlying currency, there can be no assurance that a 
liquid secondary market will exist for a particular option at any specific 
time. In addition, options on foreign currencies are affected by all of those 
factors which influence foreign exchange rates and investments generally. 

   The value of a foreign currency option depends upon the value of the 
underlying currency relative to the U.S. dollar. As a result, the price of 
the option position may vary with changes in the value of either or both 
currencies and have no relationship to the investment merits of a foreign 
security, including foreign securities held in a "hedged" investment 
portfolio. Because foreign currency transactions occurring in the interbank 
market involve 

                               17           
<PAGE>
substantially larger amounts than those that may be involved in the use of 
foreign currency options, investors may be disadvantaged by having to deal in 
an odd lot market (generally consisting of transactions of less than $1 
million) for the underlying foreign currencies at prices that are less 
favorable than for round lots. 

   There is no systematic reporting of last sale information for foreign 
currencies or any regulatory requirement that quotations available through 
dealers or other market sources be firm or revised on a timely basis. 
Quotation information available is generally representative of very large 
transactions in the interbank market and thus may not reflect relatively 
smaller transactions (i.e., less than $1 million) where rates may be less 
favorable. The interbank market in foreign currencies is a global, 
around-the-clock market. To the extent that the U.S. options markets are 
closed while the markets for the underlying currencies remain open, 
significant price and rate movements may take place in the underlying markets 
that are not reflected in the options market. 

   OTC Options. Exchange-listed options are issued by the OCC (in the U.S.) 
or other clearing corporation or exchange which assures that all transactions 
in such options are properly executed. OTC options are purchased from or sold 
(written) to dealers or financial institutions which have entered into direct 
agreements with the Fund. With OTC options, such variables as expiration 
date, exercise price and premium will be agreed upon between the Fund and the 
transacting dealer, without the intermediation of a third party such as the 
OCC. If the transacting dealer fails to make or take delivery of the 
securities or amount of foreign currency underlying an option it has written, 
in accordance with the terms of that option, the Fund would lose the premium 
paid for the option as well as any anticipated benefit of the transaction. 
The Fund will engage in OTC option transactions only with member banks of the 
Federal Reserve System or primary dealers in U.S. Government securities or 
with affiliates of such banks or dealers which have capital of at least $50 
million or whose obligations are guaranteed by an entity having capital of at 
least $50 million. 

   Covered Call Writing. As stated in the Prospectus, the Fund is permitted 
to write covered call options on portfolio securities and on the U.S. Dollar 
and foreign currencies in which they are denominated, without limit, in order 
to aid in achieving its investment objectives. Generally, a call option is 
"covered" if the Fund owns, or has the right to acquire, without additional 
cash consideration (or for additional cash consideration held for the Fund by 
its Custodian in a segregated account) the underlying security (currency) 
subject to the option except that in the case of call options on U.S. 
Treasury Bills, the Fund might own U.S. Treasury Bills of a different series 
from those underlying the call option, but with a principal amount and value 
corresponding to the exercise price and a maturity date no later than that of 
the security (currency) deliverable under the call option. A call option is 
also covered if the Fund holds a call on the same security as the underlying 
security (currency) of the written option, where the exercise price of the 
call used for coverage is equal to or less than the exercise price of the 
call written or greater than the exercise price of the call written if the 
mark to market difference is maintained by the Fund in cash, U.S. Government 
securities or other liquid portfolio securities which the Fund holds in a 
segregated account maintained with its Custodian. 

   The Fund will receive from the purchaser, in return for a call it has 
written, a "premium"; i.e., the price of the option. Receipt of these 
premiums may better enable the Fund to earn a higher level of current income 
than it would earn from holding the underlying securities (currencies) alone. 
Moreover, the premium received will offset a portion of the potential loss 
incurred by the Fund if the securities (currencies) underlying the option are 
ultimately sold (exchanged) by the Fund at a loss. Furthermore, a premium 
received on a call written on a foreign currency will ameliorate any 
potential loss of value on the portfolio security due to a decline in the 
value of the currency. However, during the option period, the covered call 
writer has, in return for the premium on the option, given up the opportunity 
for capital appreciation above the exercise price should the market price of 
the underlying security (or the exchange rate of the currency in which it is 
denominated) increase, but has retained the risk of loss should the price of 
the underlying security (or the exchange rate of the currency in which it is 
denominated) decline. The premium received will fluctuate with varying 
economic market conditions. If the market value of the portfolio securities 
(or the currencies in which they are denominated) upon which call options 
have been written increases, the Fund may receive a lower total return from 
the portion of its portfolio upon which calls have been written than it would 
have had such calls not been written. 

   As regards listed options and certain OTC options, during the option 
period, the Fund may be required, at any time, to deliver the underlying 
security (currency) against payment of the exercise price on any calls it has 
written (exercise of certain listed and OTC options may be limited to 
specific expiration dates). This obligation 

                               18           
<PAGE>
is terminated upon the expiration of the option period or at such earlier 
time when the writer effects a closing purchase transaction. A closing 
purchase transaction is accomplished by purchasing an option of the same 
series as the option previously written. However, once the Fund has been 
assigned an exercise notice, the Fund will be unable to effect a closing 
purchase transaction. 

   Closing purchase transactions are ordinarily effected to realize a profit 
on an outstanding call option, to prevent an underlying security (currency) 
from being called, to permit the sale of an underlying security (or the 
exchange of the underlying currency) or to enable the Fund to write another 
call option on the underlying security (currency) with either a different 
exercise price or expiration date or both. The Fund may realize a net gain or 
loss from a closing purchase transaction depending upon whether the amount of 
the premium received on the call option is more or less than the cost of 
effecting the closing purchase transaction. Any loss incurred in a closing 
purchase transaction may be wholly or partially offset by unrealized 
appreciation in the market value of the underlying security (currency). 
Conversely, a gain resulting from a closing purchase transaction could be 
offset in whole or in part or exceeded by a decline in the market value of 
the underlying security (currency). 

   If a call option expires unexercised, the Fund realizes a gain in the 
amount of the premium on the option less the commission paid. Such a gain, 
however, may be offset by depreciation in the market value of the underlying 
security (currency) during the option period. If a call option is exercised, 
the Fund realizes a gain or loss from the sale of the underlying security 
(currency) equal to the difference between the purchase price of the 
underlying security (currency) and the proceeds of the sale of the security 
(currency) plus the premium received on the option less the commission paid. 

   Options written by the Fund will normally have expiration dates of up to 
eighteen months from the date written. The exercise price of a call option 
may be below, equal to or above the current market value of the underlying 
security at the time the option is written. See "Risks of Transactions in 
Futures Contracts and Related Options," below. 

   Covered Put Writing. As a writer of a covered put option, the Fund incurs 
an obligation to buy the security underlying the option from the purchaser of 
the put, at the option's exercise price at any time during the option period, 
at the purchaser's election (certain listed and OTC put options written by 
the Fund will be exercisable by the purchaser only on a specific date). A put 
is "covered" if, at all times, the Fund maintains, in a segregated account 
maintained on its behalf at the Fund's Custodian, cash, U.S. Government 
Securities or other liquid portfolio securities in an amount equal to at 
least the exercise price of the option, at all times during the option 
period. Similarly, a short put position could be covered by the Fund by its 
purchase of a put option on the same security (currency) as the underlying 
security of the written option, where the exercise price of the purchased 
option is equal to or more than the exercise price of the put written or less 
than the exercise price of the put written if the marked to market difference 
is maintained by the Fund in cash, U.S. Government Securities or other liquid 
portfolio securities which the Fund holds in a segregated account maintained 
at its Custodian. In writing puts, the Fund assumes the risk of loss should 
the market value of the underlying security (currency) decline below the 
exercise price of the option (any loss being decreased by the receipt of the 
premium on the option written). In the case of listed options, during the 
option period, the Fund may be required, at any time, to make payment of the 
exercise price against delivery of the underlying security (currency). The 
operation of and limitations on covered put options in other respects are 
substantially identical to those of call options. 

   The Fund will write put options for three purposes: (1) to receive the 
income derived from the premiums paid by purchasers; (2) when the Adviser 
wishes to purchase the security (or a security denominated in the currency 
underlying the option) underlying the option at a price lower than its 
current market price, in which case it will write the covered put at an 
exercise price reflecting the lower purchase price sought; and (3) to close 
out a long put option position. The potential gain on a covered put option is 
limited to the premium received on the option (less the commissions paid on 
the transaction) while the potential loss equals the differences between the 
exercise price of the option and the current market price of the underlying 
securities (currencies) when the put is exercised, offset by the premium 
received (less the commissions paid on the transaction). 

   Purchasing Call and Put Options. As stated in the Prospectus, the Fund may 
purchase listed and OTC call and put options in amounts equalling up to 5% of 
its total assets. The Fund may purchase a call option in order to close out a 
covered call position (see "Covered Call Writing" above), to protect against 
an increase in price of a security it anticipates purchasing or, in the case 
of a call option on foreign currency, to hedge against an adverse exchange 

                               19           
<PAGE>
rate move of the currency in which the security it anticipates purchasing is 
denominated vis-a-vis the currency in which the exercise price is 
denominated. The purchase of the call option to effect a closing transaction 
on a call written over-the-counter may be a listed or an OTC option. In 
either case, the call purchased is likely to be on the same securities 
(currencies) and have the same terms as the written option. If purchased 
over-the-counter, the option would generally be acquired from the dealer or 
financial institution which purchased the call written by the Fund. 

   The Fund may purchase put options on securities (currencies) which it 
holds in its portfolio to protect itself against a decline in the value of 
the security and to close out written put option positions. If the value of 
the underlying security (currency) were to fall below the exercise price of 
the put purchased in an amount greater than the premium paid for the option, 
the Fund would incur no additional loss. In addition, the Fund may sell a put 
option which it has previously purchased prior to the sale of the securities 
(currencies) underlying such option. Such a sale would result in a net gain 
or loss depending on whether the amount received on the sale is more or less 
than the premium and other transaction costs paid on the put option which is 
sold. And such gain or loss could be offset in whole or in part by a change 
in the market value of the underlying security (currency). If a put option 
purchased by the Fund expired without being sold or exercised, the premium 
would be lost. 

   Risks of Options Transactions. During the option period, the covered call 
writer has, in return for the premium on the option, given up the opportunity 
for capital appreciation above the exercise price should the market price of 
the underlying security (or the value of its denominated currency) increase, 
but has retained the risk of loss should the price of the underlying security 
(or the value of its denominated currency) decline. The writer has no control 
over the time when it may be required to fulfill its obligation as a writer 
of the option. Once an option writer has received an exercise notice, it 
cannot effect a closing purchase transaction in order to terminate its 
obligation under the option and must deliver or receive the underlying 
securities at the exercise price. 

   Prior to exercise or expiration, an option position can only be terminated 
by entering into a closing purchase or sale transaction. If a covered call 
option writer is unable to effect a closing purchase transaction or to 
purchase an offsetting OTC option, it cannot sell the underlying security 
until the option expires or the option is exercised. Accordingly, a covered 
call option writer may not be able to sell an underlying security at a time 
when it might otherwise be advantageous to do so. A secured put option writer 
who is unable to effect a closing purchase transaction or to purchase an 
offsetting OTC option would continue to bear the risk of decline in the 
market price of the underlying security until the option expires or is 
exercised. In addition, a secured put writer would be unable to utilize the 
amount held in cash or U.S. Government or other liquid portfolio securities 
as security for the put option for other investment purposes until the 
exercise or expiration of the option. 

   The Fund's ability to close out its position as a writer of an option is 
dependent upon the existence of a liquid secondary market on Option 
Exchanges. There is no assurance that such a market will exist, particularly 
in the case of OTC options, as such options will generally only be closed out 
by entering into a closing purchase transaction with the purchasing dealer. 
However, the Fund may be able to purchase an offsetting option which does not 
close out its position as a writer but constitutes an asset of equal value to 
the obligation under the option written. If the Fund is not able to either 
enter into a closing purchase transaction or purchase an offsetting position, 
it will be required to maintain the securities subject to the call, or the 
collateral underlying the put, even though it might not be advantageous to do 
so, until a closing transaction can be entered into (or the option is 
exercised or expires). 

   Among the possible reasons for the absence of a liquid secondary market on 
an Exchange are: (i) insufficient trading interest in certain options; (ii) 
restrictions on transactions imposed by an Exchange; (iii) trading halts, 
suspensions or other restrictions imposed with respect to particular classes 
or series of options or underlying securities; (iv) interruption of the 
normal operations on an Exchange; (v) inadequacy of the facilities of an 
Exchange or the OCC to handle current trading volume; or (vi) a decision by 
one or more Exchanges to discontinue the trading of options (or a particular 
class or series of options), in which event the secondary market on that 
Exchange (or in that class or series of options) would cease to exist, 
although outstanding options on that Exchange that had been issued by the OCC 
as a result of trades on that Exchange would generally continue to be 
exercisable in accordance with their terms. 

   In the event of the bankruptcy of a broker through which the Fund engages 
in transactions in options, the Fund could experience delays and/or losses in 
liquidating open positions purchased or sold through the broker 

                               20           
<PAGE>
and/or incur a loss of all or part of its margin deposits with the broker. 
Similarly, in the event of the bankruptcy of the writer of an OTC option 
purchased by the Fund, the Fund could experience a loss of all or part of the 
value of the option. Transactions are entered into by the Fund only with 
brokers or financial institutions deemed creditworthy by the Fund's 
management. 

   Each of the Exchanges has established limitations governing the maximum 
number of options on the same underlying security or futures contract 
(whether or not covered) which may be written by a single investor, whether 
acting alone or in concert with others (regardless of whether such options 
are written on the same or different Exchanges or are held or written on one 
or more accounts or through one or more brokers). An Exchange may order the 
liquidation of positions found to be in violation of these limits and it may 
impose other sanctions or restrictions. These position limits may restrict 
the number of listed options which the Fund may write. 

   The hours of trading for options may not conform to the hours during which 
the underlying securities are traded. To the extent that the option markets 
close before the markets for the underlying securities, significant price and 
rate movements can take place in the underlying markets that cannot be 
reflected in the option markets. 

   The extent to which the Fund may enter into transactions involving options 
may be limited by the Internal Revenue Code's requirements for qualification 
as a regulated investment company and the Fund's intention to qualify as such 
(see "Dividends, Distributions and Taxes"). 

   Futures Contracts. As stated in the Prospectus, the Fund may purchase and 
sell interest rate, currency, and index futures contracts ("futures 
contracts"), that are traded on U.S. and foreign commodity exchanges, on such 
underlying securities as U.S. Treasury bonds, notes and bills and/or any 
foreign government fixed-income security ("interest rate" futures), on 
various currencies ("currency futures") and on such indexes of U.S. and 
foreign securities as may exist or come into being ("index" futures). 

   The Fund will purchase or sell interest rate futures contracts for the 
purpose of hedging some or all of the value of its portfolio securities (or 
anticipated portfolio securities) against changes in prevailing interest 
rates. If the Adviser anticipates that interest rates may rise and, 
concomitantly, the price of certain of its portfolio securities fall, the 
Fund may sell an interest rate futures contract. If declining interest rates 
are anticipated, the Fund may purchase an interest rate futures contract to 
protect against a potential increase in the price of securities the Fund 
intends to purchase. Subsequently, appropriate securities may be purchased by 
the Fund in an orderly fashion; as securities are purchased, corresponding 
futures positions would be terminated by offsetting sales of contracts. 

   The Fund will purchase or sell index futures contracts for the purpose of 
hedging some or all of its portfolio (or anticipated portfolio) securities 
against changes in their prices. If the Adviser anticipates that the prices 
of securities held by the Fund may fall, the Fund may sell an index futures 
contract. Conversely, if the Fund wishes to hedge against anticipated price 
rises in those securities which the Fund intends to purchase, the Fund may 
purchase an index futures contract. 

   The Fund will purchase or sell currency futures on currencies in which its 
portfolio securities (or anticipated portfolio securities) are denominated 
for the purposes of hedging against anticipated changes in currency exchange 
rates. The Fund will enter into currency futures contracts for the same 
reasons as set forth above for entering into forward foreign currency 
contracts; namely, to "lock-in" the value of a security purchased or sold in 
a given currency vis-a-vis a different currency or to hedge against an 
adverse currency exchange rate movement of a portfolio security's (or 
anticipated portfolio security's) denominated currency vis-a-vis a different 
currency. 

   In addition to the above, interest rate, index and currency futures will 
be bought or sold in order to close out a short or long position maintained 
by the Fund in a corresponding futures contract. 

   Although most interest rate futures contracts call for actual delivery or 
acceptance of securities, the contracts usually are closed out before the 
settlement date without the making or taking of delivery. A futures contract 
sale is closed out by effecting a futures contract purchase for the same 
aggregate amount of the specific type of security (currency) and the same 
delivery date. If the sale price exceeds the offsetting purchase price, the 
seller would be paid the difference and would realize a gain. If the 
offsetting purchase price exceeds the sale price, the seller would pay the 
difference and would realize a loss. Similarly, a futures contract purchase 
is closed out by effecting a futures contract sale for the same aggregate 
amount of the specific type of security (currency) and the same delivery 
date. If the offsetting sale price exceeds the purchase price, the purchaser 
would realize a gain, whereas if the purchase price exceeds the offsetting 
sale price, the purchaser would realize a loss. There is no assurance that 
the Fund will be able to enter into a closing transaction.

   Interest Rate Futures Contracts. When the Fund enters into an interest 
rate futures contract, it is initially required to deposit with the Fund's 
Custodian, in a segregated account in the name of the broker performing the 
transaction, an "initial margin" of cash or U.S. Government securities or 
other liquid portfolio securities equal to approximately 2% of the contract 
amount. Initial margin requirements are established by the Exchanges on which 
futures contracts trade and may, from time to time, change. In addition, 
brokers may establish margin deposit requirements in excess of those required 
by the Exchanges. 

   Initial margin in futures transactions is different from margin in 
securities transactions in that initial margin does not involve the borrowing 
of funds by a brokers' client but is, rather, a good faith deposit on the 
futures contract which will be returned to the Fund upon the proper 
termination of the futures contract. The margin deposits made are 
marked-to-market daily and the Fund may be required to make subsequent 
deposits of cash or U.S. Government Securities called "variation margin," 
with the Fund's futures contract clearing broker, which are reflective of 
price fluctuations in the futures contract. Currently, interest rate futures 
contracts can be purchased on debt securities such as U.S. Treasury Bills and 
Bonds, U.S. Treasury Notes with maturities between 6 1/2 and 10 years, GNMA 
Certificates and Bank Certificates of Deposit. 

   Currency Futures. Generally, foreign currency futures provide for the 
delivery of a specified amount of a given currency, on the exercise date, for 
a set exercise price denominated in U.S. dollars or other currency. Foreign 
currency futures contracts would be entered into for the same reason and 
under the same circumstances as forward foreign currency exchange contracts. 
The Adviser will assess such factors as cost spreads, liquidity and 
transaction costs in determining whether to utilize futures contracts or 
forward contracts in its foreign currency transactions and hedging strategy. 
Currently, currency futures exist for, among other foreign currencies, 
Canadian dollars. 

   Purchasers and sellers of foreign currency futures contracts are subject 
to the same risks that apply to the buying and selling of futures generally. 
In addition, there are risks associated with foreign currency futures 
contracts and their use as a hedging device similar to those associated with 
options on foreign currencies described above. Further, settlement of a 
foreign currency futures contract must occur within the country issuing the 
underlying currency. Thus, the Fund must accept or make delivery of the 
underlying foreign currency in accordance with any U.S. or foreign 
restrictions or regulations regarding the maintenance of foreign banking 
arrangements by U.S. residents and may be required to pay any fees, taxes or 
charges associated with such delivery which are assessed in the issuing 
country. 

   Options on foreign currency futures contracts may involve certain 
additional risks. Trading options on foreign currency futures contracts is 
relatively new. The ability to establish and close out positions on such 
options is subject to the maintenance of a liquid secondary market. To reduce 
this risk, the Fund will not purchase or write options on foreign currency 
futures contracts unless and until, in the Adviser's opinion, the market for 
such options has developed sufficiently that the risks in connection with 
such options are not greater than the risks in connection with transactions 
in the underlying foreign currency futures contracts. 

   Index Futures Contracts. As discussed in the Prospectus, the Fund may 
invest in index futures contracts. An index futures contract sale creates an 
obligation by the Fund, as seller, to deliver cash at a specified future 
time. An index futures contract purchase would create an obligation by the 
Fund, as purchaser, to take delivery of cash at a specified future time. 
Futures contracts on indexes do not require the physical delivery of 
securities, but provide for a final cash settlement on the expiration date 
which reflects accumulated profits and losses credited or debited to each 
party's account. 

   The Fund is required to maintain margin deposits with brokerage firms 
through which it effects index futures contracts in a manner similar to that 
described above for interest rate futures contracts. In addition, due to 
current industry practice, daily variations in gains and losses on open 
contracts are required to be reflected in cash in the form of variation 
margin payments. The Fund may be required to make additional margin payments 
during the term of the contract. 

   At any time prior to expiration of the futures contract, the Fund may 
elect to close the position by taking an opposite position which will operate 
to terminate the Fund's position in the futures contract. A final 
determination of variation margin is then made, additional cash is required 
to be paid by or released to the Fund and the Fund realizes a loss or gain. 

                               22           
<PAGE>
   Options on Futures Contracts. The Fund may purchase and write call and put 
options on futures contracts which are traded on an exchange and enter into 
closing transactions with respect to such options to terminate an existing 
position. An option on a futures contract gives the purchaser the right (in 
return for the premium paid) to assume a position in a futures contract (a 
long position if the option is a call and a short position if the option is a 
put) at a specified exercise price at any time during the term of the option. 
Upon exercise of the option, the delivery of the futures position by the 
writer of the option to the holder of the option is accompanied by delivery 
of the accumulated balance in the writer's futures margin account, which 
represents the amount by which the market price of the futures contract at 
the time of exercise exceeds, in the case of a call, or is less than, in the 
case of a put, the exercise price of the option on the futures contract. 

   The Fund will purchase and write options on futures contracts for 
identical purposes to those set forth above for the purchase of a futures 
contract (purchase of a call option or sale of a put option) and the sale of 
a futures contract (purchase of a put option or sale of a call option), or to 
close out a long or short position in futures contracts. If, for example, the 
Adviser wished to protect against an increase in interest rates and the 
resulting negative impact on the value of a portion of its fixed-income 
portfolio, it might write a call option on an interest rate futures contract, 
the underlying security of which correlates with the portion of the portfolio 
the Adviser seeks to hedge. Any premiums received in the writing of options 
on futures contracts may, of course, provide a further hedge against losses 
resulting from price declines in portions of the Fund's portfolio. 

   Limitations on Futures Contracts and Options on Futures. The Fund may not 
enter into futures contracts or purchase related options thereon if, 
immediately thereafter, the amount committed to margin plus the amount paid 
for premiums for unexpired options on futures contracts exceeds 5% of the 
value of the Fund's total assets, after taking into account unrealized gains 
and unrealized losses on such contracts it has entered into, provided, 
however, that in the case of an option that is in-the-money (the exercise 
price of the call (put) option is less (more) than the market price of the 
underlying security) at the time of purchase, the in-the-money amount may be 
excluded in calculating the 5%. However, there is no overall limitation on 
the percentage of the Fund's assets which may be subject to a hedge position. 
Except as described above, there are no other limitations on the use of 
futures and options thereon by the Fund. 

   The writer of an option on a futures contract is required to deposit 
initial and variation margin pursuant to requirements similar to those 
applicable to futures contracts. Premiums received from the writing of an 
option on a futures contract are included in initial margin deposits. 

   Risks of Transactions in Futures Contracts and Related Options. As stated 
in the Prospectus, the Fund may sell a futures contract to protect against 
the decline in the value of securities (or the currency in which they are 
denominated) held by the Fund. However, it is possible that the futures 
market may advance and the value of securities (or the currency in which they 
are denominated) held in the portfolio of the Fund may decline. If this 
occurred, the Fund would lose money on the futures contract and also 
experience a decline in value of its portfolio securities. However, while 
this could occur for a very brief period or to a very small degree, over time 
the value of a diversified portfolio will tend to move in the same direction 
as the futures contracts. 

   If the Fund purchases a futures contract to hedge against the increase in 
value of securities it intends to buy (or the currency in which they are 
denominated), and the value of such securities (currencies) decreases, then 
the Fund may determine not to invest in the securities as planned and will 
realize a loss on the futures contract that is not offset by a reduction in 
the price of the securities. 

   If the Fund has sold a call option on a futures contract, it will cover 
this position by holding, in a segregated account maintained at its 
Custodian, cash, U.S. Government Securities or other liquid portfolio 
securities equal in value (when added to any initial or variation margin on 
deposit) to the market value of the securities (currencies) underlying the 
futures contract or the exercise price of the option. Such a position may 
also be covered by owning the securities (currencies) underlying the futures 
contract, or by holding a call option permitting the Fund to purchase the 
same contract at a price no higher than the price at which the short position 
was established. 

   In addition, if the Fund holds a long position in a futures contract it 
will hold cash, U.S. Government Securities or other liquid portfolio 
securities equal to the purchase price of the contract (less the amount of 
initial or variation margin on deposit) in a segregated account maintained 
for the Fund by its Custodian. Alternatively, the Fund could cover its long 
position by purchasing a put option on the same futures contract with an 
exercise price as high or higher than the price of the contract held by the 
Fund. 

                               23           
<PAGE>
   Exchanges limit the amount by which the price of a futures contract may 
move on any day. If the price moves equal the daily limit on successive days, 
then it may prove impossible to liquidate a futures position until the daily 
limit moves have ceased. In the event of adverse price movements, the Fund 
would continue to be required to make daily cash payments of variation margin 
on open futures positions. In such situations, if the Fund has insufficient 
cash, it may have to sell portfolio securities to meet daily variation margin 
requirements at a time when it may be disadvantageous to do so. In addition, 
the Fund may be required to take or make delivery of the instruments 
underlying interest rate futures contracts it holds at a time when it is 
disadvantageous to do so. The inability to close out options and futures 
positions could also have an adverse impact on the Fund's ability to 
effectively hedge its portfolio. 

   Futures contracts and options thereon which are purchased or sold on 
foreign commodities exchanges may have greater price volatility than their 
U.S. counterparts. Furthermore, foreign commodities exchanges may be less 
regulated and under less governmental scrutiny than U.S. exchanges. Brokerage 
commissions, clearing costs and other transaction costs may be higher on 
foreign exchanges. Greater margin requirements may limit the Fund's ability 
to enter into certain commodity transactions on foreign exchanges. Moreover, 
differences in clearance and delivery requirements on foreign exchanges may 
occasion delays in the settlement of the Fund's transactions effected on 
foreign exchanges. 

   In the event of the bankruptcy of a broker through which the Fund engages 
in transactions in futures or options thereon, the Fund could experience 
delays and/or losses in liquidating open positions purchased or sold through 
the broker and/or incur a loss of all or part of its margin deposits with the 
broker. Similarly, in the event of the bankruptcy of the writer of an OTC 
option purchased by the Fund, the Fund could experience a loss of all or part 
of the value of the option. Transactions are entered into by the Fund only 
with brokers or financial institutions deemed creditworthy by the Adviser. 

   While the futures contracts and options transactions to be engaged in by 
the Fund for the purpose of hedging the Fund's portfolio securities are not 
speculative in nature, there are risks inherent in the use of such 
instruments. One such risk which may arise in employing futures contracts to 
protect against the price volatility of portfolio securities (and the 
currencies in which they are denominated) is that the prices of securities 
and indexes subject to futures contracts (and thereby the futures contract 
prices) may correlate imperfectly with the behavior of the cash prices of the 
Fund's portfolio securities (and the currencies in which they are 
denominated). Another such risk is that prices of interest rate futures 
contracts may not move in tandem with the changes in prevailing interest 
rates against which the Fund seeks a hedge. A correlation may also be 
distorted by the fact that the futures market is dominated by short-term 
traders seeking to profit from the difference between a contract or security 
price objective and their cost of borrowed funds. Such distortions are 
generally minor and would diminish as the contract approached maturity. 

   There may exist an imperfect correlation between the price movements of 
futures contracts purchased by the Fund and the movements in the prices of 
the securities (currencies) which are the subject of the hedge. If 
participants in the futures market elect to close out their contracts through 
offsetting transactions rather than meet margin deposit requirements, 
distortions in the normal relationship between the debt securities or 
currency markets and futures markets could result. Price distortions could 
also result if investors in futures contracts opt to make or take delivery of 
underlying securities rather than engage in closing transactions due to the 
resultant reduction in the liquidity of the futures market. In addition, due 
to the fact that, from the point of view of speculators, the deposit 
requirements in the futures markets are less onerous than margin requirements 
in the cash market, increased participation by speculators in the futures 
market could cause temporary price distortions. Due to the possibility of 
price distortions in the futures market and because of the imperfect 
correlation between movements in the prices of securities and movements in 
the prices of futures contracts, a correct forecast of interest rate trends 
may still not result in a successful hedging transaction. 

   As stated in the Prospectus, there is no assurance that a liquid secondary 
market will exist for futures contracts and related options in which the Fund 
may invest. In the event a liquid market does not exist, it may not be 
possible to close out a futures position, and in the event of adverse price 
movements, the Fund would continue to be required to make daily cash payments 
of variation margin. In addition, limitations imposed by an exchange or board 
of trade on which futures contracts are traded may compel or prevent the Fund 
from closing out a contract which may result in reduced gain or increased 
loss to the Fund. The absence of a liquid market in futures contracts might 
cause the Fund to make or take delivery of the underlying securities 
(currencies) at a time when it may be disadvantageous to do so. 

                               24           
<PAGE>
   The extent to which the Fund may enter into transactions involving futures 
contracts and options thereon may be limited by the Internal Revenue Code's 
requirements for qualification as a regulated investment company and the 
Fund's intention to qualify as such (see "Dividends, Distributions and 
Taxes"). 

   Compared to the purchase or sale of futures contracts, the purchase of 
call or put options on futures contracts involves less potential risk to the 
Fund because the maximum amount at risk is the premium paid for the options 
(plus transaction costs). However, there may be circumstances when the 
purchase of a call or put option on a futures contract would result in a loss 
to the Fund notwithstanding that the purchase or sale of a futures contract 
would not result in a loss, as in the instance where there is no movement in 
the prices of the futures contract or underlying securities (currencies). 

REVERSE REPURCHASE AGREEMENTS AND DOLLAR ROLLS 

   As stated in the Prospectus, the Fund may also use reverse repurchase 
agreements and dollar rolls as part of its investment strategy. Reverse 
repurchase agreements involve sales by the Fund of portfolio assets 
concurrently with an agreement by the Fund to repurchase the same assets at a 
later date at a fixed price. Generally, the effect of such a transaction is 
that the Fund can recover all or most of the cash invested in the portfolio 
securities involved during the term of the reverse repurchase agreement, 
while it will be able to keep the interest income associated with those 
portfolio securities. Such transactions are only advantageous if the interest 
cost to the Fund of the reverse repurchase transaction is less than the cost 
of obtaining the cash otherwise. 

   The Fund may enter into dollar rolls in which the Fund sells securities 
for delivery in the current month and simultaneously contracts to repurchase 
substantially similar (same type and coupon) securities on a specified future 
date. During the roll period, the Fund foregoes principal and interest paid 
on the securities. The Fund is compensated by the difference between the 
current sales price and the lower forward price for the future purchase 
(often referred to as the "drop") as well as by the interest earned on the 
cash proceeds of the initial sale. 

   The Fund will establish a segregated account with its custodian bank in 
which it will maintain cash, U.S. Government securities or other liquid 
portfolio securities equal in value to its obligations in respect of reverse 
repurchase agreements and dollar rolls. 

LENDING OF PORTFOLIO SECURITIES 

   Consistent with applicable regulatory requirements, the Fund may lend its 
portfolio securities to brokers, dealers and other financial institutions, 
provided that such loans are callable at any time by the Fund (subject to 
notice provisions described below), and are at all times secured by cash or 
money market instruments, which are maintained in a segregated account 
pursuant to applicable regulations and that are equal to at least the market 
value, determined daily, of the loaned securities. The advantage of such 
loans is that the Fund continues to receive the income on the loaned 
securities while at the same time earning interest on the cash amounts 
deposited as collateral, which will be invested in short-term obligations. 
The Fund will not lend its portfolio securities if such loans are not 
permitted by the laws or regulations of any state in which its shares are 
qualified for sale and will not lend more than 25% of the value of its total 
assets. A loan may be terminated by the borrower on one business day's 
notice, or by the Fund on two business days' notice. If the borrower fails to 
deliver the loaned securities within two days after receipt of notice, the 
Fund could use the collateral to replace the securities while holding the 
borrower liable for any excess of replacement cost over collateral. As with 
any extensions of credit, there are risks of delay in recovery and in some 
cases even loss of rights in the collateral should the borrower of the 
securities fail financially. However, these loans of portfolio securities 
will only be made to firms deemed by the Fund's management to be creditworthy 
and when the income which can be earned from such loans justifies the 
attendant risks. Upon termination of the loan, the borrower is required to 
return the securities to the Fund. Any gain or loss in the market price 
during the loan period would inure to the Fund. The creditworthiness of firms 
to which the Fund lends its portfolio securities will be monitored on an 
ongoing basis by the Adviser pursuant to procedures adopted and reviewed, on 
an ongoing basis, by the Board of Trustees of the Fund. 

   When voting or consent rights which accompany loaned securities pass to 
the borrower, the Fund will follow the policy of calling the loaned 
securities, to be delivered within one day after notice, to permit the 
exercise of such rights if the matters involved would have a material effect 
on the Fund's investment in such loaned securities. The Fund will pay 
reasonable finder's, administrative and custodial fees in connection with a 
loan of its securities. 

                               25           
<PAGE>
WHEN-ISSUED AND DELAYED DELIVERY SECURITIES AND FORWARD COMMITMENTS 

   From time to time, in the ordinary course of business, the Fund may 
purchase securities on a when-issued or delayed delivery basis and may 
purchase or sell securities on a forward commitment basis. When such 
transactions are negotiated, the price is fixed at the time of the 
commitment, but delivery and payment can take place a month or more after the 
date of the commitment. The securities so purchased or sold are subject to 
market fluctuation and no interest or dividends accrue to the purchaser prior 
to the settlement date. While the Fund will only purchase securities on a 
when-issued, delayed delivery or forward commitment basis with the intention 
of acquiring the securities, the Fund may sell the securities before the 
settlement date, if it is deemed advisable. At the time the Fund makes the 
commitment to purchase or sell securities on a when-issued, delayed delivery 
or forward commitment basis, the Fund will record the transaction and 
thereafter reflect the value, each day, of such security purchased or, if a 
sale, the proceeds to be received, in determining its net asset value. At the 
time of delivery of the securities, the value may be more or less than the 
purchase or sale price. The Fund will also establish a segregated account 
with the Fund's custodian bank in which it will continuously maintain cash or 
U.S. Government Securities or other liquid portfolio securities equal in 
value to commitments to purchase securities on a when-issued, delayed 
delivery or forward commitment basis; subject to this requirement, the Fund 
may purchase securities on such basis without limit. An increase in the 
percentage of the Fund's assets committed to the purchase of securities on a 
when-issued or delayed delivery basis may increase the volatility of the 
Fund's net asset value. 

WHEN, AS AND IF ISSUED SECURITIES 

   The Fund may purchase securities on a "when, as and if issued" basis under 
which the issuance of the security depends upon the occurrence of a 
subsequent event, such as approval of a merger, corporate reorganization, 
leveraged buyout or debt restructuring. The commitment for the purchase of 
any such security will not be recognized in the portfolio of the Fund until 
the Adviser determines that issuance of the security is probable. At such 
time, the Fund will record the transaction and, in determining its net asset 
value, will reflect the value of the security daily. At such time, the Fund 
will also establish a segregated account with its custodian bank in which it 
will continuously maintain cash or U.S. Government securities or other liquid 
portfolio securities equal in value to recognized commitments for such 
securities. Settlement of the trade will occur within five business days of 
the occurrence of the subsequent event. Once a segregated account has been 
established, if the anticipated event does not occur and the securities are 
not issued the Fund will have lost an investment opportunity. The Fund may 
purchase securities on such basis without limit. An increase in the 
percentage of the Fund's assets committed to the purchase of securities on a 
"when, as and if issued" basis may increase the volatility of its net asset 
value. The Fund may also sell securities on a "when, as and if issued" basis 
provided that the issuance of the security will result automatically from the 
exchange or conversion of a security owned by the Fund at the time of the 
sale. 

PORTFOLIO TURNOVER 

   It is anticipated that the Fund's portfolio turnover rate generally will 
not exceed 100%. A 100% turnover rate would occur, for example, if 100% of 
the securities held in the Fund's portfolio (excluding all securities whose 
maturities at acquisition were one year or less) were sold and replaced 
within one year. 

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

   In addition to the investment restrictions enumerated in the Prospectus, 
the investment restrictions listed below have been adopted by the Fund as 
fundamental policies, except as otherwise indicated. Under the Act, a 
fundamental policy may not be changed without the vote of a majority of the 
outstanding voting securities of the Fund, as defined in the Act. Such a 
majority is defined as the lesser of (a) 67% or more of the shares present at 
a meeting of shareholders, if the holders of 50% of the outstanding shares of 
the Fund are present or represented by proxy or (b) more than 50% of the 
outstanding shares of the Fund. 

   The Fund may not: 

     1. Purchase or sell real estate or interests therein (including limited 
    partnership interests), although the Fund may purchase securities of 
    issuers which engage in real estate operations and securities secured by 
    real estate or interests therein. 

                               26           
<PAGE>
     2. Purchase oil, gas or other mineral leases, rights or royalty contracts 
    or exploration or development programs, except that the Fund may invest in 
    the securities of companies which operate, invest in, or sponsor such 
    programs. 

     3. Borrow money, except that the Fund (i) may borrow from a bank for 
    temporary or emergency purposes in amounts not exceeding 5% (taken at the 
    lower of cost or current value) of its total assets (not including the 
    amount borrowed), and (ii) may engage in reverse repurchase agreements and 
    dollar rolls. 

     4. Pledge its assets or assign or otherwise encumber them except to 
    secure borrowings effected within the limitations set forth in restriction 
    (3). For the purpose of this restriction, collateral arrangements with 
    respect to initial or variation margin for futures are not deemed to be 
    pledges of assets. 

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

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

     7. Make short sales of securities. 

     8. Purchase securities on margin, except for such short-term loans as are 
    necessary for the clearance of portfolio securities. The deposit or 
    payment by the Fund of initial or variation margin in connection with 
    futures contracts is not considered the purchase of a security on margin. 

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

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

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

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

   
   Subject to the general supervision of the Trustees, the Adviser is 
responsible for decisions to buy and sell securities for the Fund, the 
selection of brokers and dealers to effect the transactions, and the 
negotiation of brokerage commissions, if any. Purchases and sales of 
securities on a stock exchange are effected through brokers who charge a 
commission for their services. In the over-the-counter market, securities are 
generally traded on a "net" basis with dealers acting as principal for their 
own accounts without a stated commission, although the price of the security 
usually includes a profit to the dealer. In addition, securities may 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. Futures transactions will usually be effected through a broker 
and a commission will be charged. On occasion, the Fund may also purchase 
certain money market instruments directly from an issuer, in which case no 
commissions or discounts are paid. During the fiscal years ended October 31, 
1995, 1996 and 1997, the Fund paid no brokerage commissions. 
    

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

   The policy of the Fund regarding purchases and sales of securities for its 
portfolio is that primary consideration will be given to obtaining the most 
favorable prices and efficient executions of transactions. 

                               27           
<PAGE>
Consistent with this policy, when securities transactions are effected on a 
stock exchange, the Fund's policy is to pay commissions which are considered 
fair and reasonable without necessarily determining that the lowest possible 
commissions are paid in all circumstances. The Fund believes that a 
requirement always to seek the lowest possible commission cost could impede 
effective portfolio management and preclude the Fund and the Adviser from 
obtaining a high quality of brokerage and research services. In seeking to 
determine the reasonableness of brokerage commissions paid in any 
transaction, the Adviser 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 Adviser effects 
transactions with those brokers and dealers who the Adviser believes provide 
the most favorable prices and are capable of providing efficient executions. 
If the Adviser believes such prices and executions are obtainable from more 
than one broker or dealer, it may give consideration to placing portfolio 
transactions with those brokers and dealers who also furnish research and 
other services to the Fund or the Adviser. Such services may include, but are 
not limited to, any one or more of the following: reports on industries and 
companies, economic analyses and review of business conditions, portfolio 
strategy, analytic computer software, account performance services, computer 
terminals and various trading and/or quotation equipment. They also include 
advice from broker-dealers as to the value of securities, availability of 
securities, availability of buyers, and availability of sellers. In addition, 
they include recommendations as to purchase and sale of individual securities 
and timing of such transactions. The Fund will not purchase at a higher price 
or sell at a lower price in connection with transactions effected with a 
dealer, acting as principal, who furnishes research services to the Fund than 
would be the case if no weight were given by the Fund to the dealer's 
furnishing of such services. 

   The information and services received by the Adviser from brokers and 
dealers may be of benefit to the Adviser 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 Adviser and thereby reduce its expenses, it is of 
indeterminable value and the advisory fee paid to the Adviser is not reduced 
by any amount that may be attributable to the value of such services. 

   
   Consistent with the policy described above, brokerage transactions in 
securities listed on exchanges or admitted to unlisted trading privileges may 
be effected through DWR, Morgan Stanley & Co. Incorporated and other 
affiliated brokers and dealers. In order for an affiliated broker or dealer 
to effect any portfolio transactions for the Fund, the commissions, fees or 
other remuneration received by the affiliated broker or dealer 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 the affiliated broker or dealer 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 Board of Trustees of the Fund, including a majority of the 
Trustees who are not "interested" persons of the Fund, as defined in the Act, 
have adopted procedures which are reasonably designed to provide that any 
commissions, fees or other remuneration paid to an affiliated broker or 
dealer are consistent with the foregoing standard. During the fiscal years 
ended October 31, 1995, 1996 and 1997, the Fund paid no brokerage commissions 
to DWR. During the period June 1, 1997 through October 31, 1997, the Fund 
paid no brokerage commissions to Morgan Stanley & Co. Incorporated (Morgan 
Stanley & Co. Incorporated became an affiliate of the Fund on June 1, 1997). 
    

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

   
   As discussed in the Prospectus, shares of the Fund are distributed by Dean 
Witter Distributors Inc. (the "Distributor"). The Distributor has entered 
into a selected dealer agreement with DWR, which through its own sales 
organization sells shares of the Fund. In addition, the Distributor may enter 
into selected dealer agreements with other selected broker-dealers (including 
TCW Brokerage Services, an affiliate of the Adviser). The Distributor, a 
Delaware corporation, is a wholly-owned subsidiary of MSDWD. 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 was approved by the Board of Trustees, 
including all of the 
    
                               28           

<PAGE>
   
Independent Trustees, on April 24, 1997. The current Distribution Agreement 
is substantively identical to the Fund's previous distribution agreements. 
The current Distribution Agreement took effect on May 31, 1997 upon the 
consummation of the merger of Dean Witter, Discover & Co. with Morgan Stanley 
Group Inc. and is substantially identical to the Fund's prior distribution 
agreements except for its dates of effectiveness and termination. By its 
terms, the Distribution Agreement has an initial term ending April 30, 1998, 
and provides that it will remain in effect from year to year thereafter if 
approved by the Trustees. 
    

   The Distributor bears all expenses it or any selected dealer may incur in 
providing services under the Distribution Agreement. Such expenses include 
the payment of commissions for sales of the Fund's shares and incentive 
compensation to account executives. The Distributor also pays certain 
expenses in connection with the distribution of the Fund's shares, including 
the costs of preparing, printing and distributing advertising or promotional 
materials, and the costs of printing and distributing prospectuses and 
supplements thereto used in connection with the offering and sale of the 
Fund's shares. The Fund bears the costs of initial typesetting, printing and 
distribution of prospectuses and supplements thereto to shareholders. The 
Fund also bears the costs of registering the Fund and its shares under 
federal and state securities laws. The Fund and the Distributor have agreed 
to indemnify each other against certain liabilities, including liabilities 
under the Securities Act of 1933, as amended. Under the Distribution 
Agreement, the Distributor uses its best efforts in rendering services to the 
Fund, but in the absence of willful misfeasance, bad faith, gross negligence 
or reckless disregard of its obligations, the Distributor is not liable to 
the Fund or any of its shareholders for any error of judgment or mistake of 
law or for any act or omission or for any losses sustained by the Fund or its 
shareholders. 

PLAN OF DISTRIBUTION 

   As discussed in the Prospectus, the Fund has entered into a Plan of 
Distribution pursuant to Rule 12b-1 under the Act with the Distributor 
whereby the expenses of certain activities in connection with the 
distribution of shares of the Fund are reimbursed. The Plan was initially 
approved by the Trustees of the Fund on May 1, 1992 and by DWR, the then sole 
shareholder of the Fund, on May 11, 1992. The vote of the Trustees included a 
majority of the Trustees who are not and were not at the time of their votes 
interested persons of the Fund and who have and had at the time of their 
votes no direct or indirect financial interest in the operation of the Plan 
(the "Independent 12b-1 Trustees"), cast in person at a meeting called for 
the purpose of voting on such Plan. In determining to approve the Plan, the 
Trustees, including the Independent 12b-1 Trustees, concluded that, in their 
judgment, there is a reasonable likelihood that the Plan will benefit the 
Fund and its shareholders. 

   The Plan provides that the Distributor will bear the expense of all 
promotional and distribution related activities on behalf of the Fund, except 
for expenses that the Trustees determine to reimburse, as described below. 
The following activities and services may be provided by the Distributor and 
DWR or any other selected broker-dealer under the Plan: (1) compensation to 
and expenses of account executives and other employees of DWR and other 
selected dealers, including overhead and telephone expenses; (2) sales 
incentives and bonuses to sales representatives and to marketing personnel in 
connection with promoting sales of the Fund's shares; (3) expenses incurred 
in connection with promoting sales of the Fund's shares; (4) preparing and 
distributing sales literature; and (5) providing advertising and promotional 
activities, including direct mail solicitation and television, radio, 
newspaper, magazine and other media advertisements. 

   
   The Fund is authorized to reimburse specific expenses incurred or to be 
incurred in promoting the distribution of the Fund's shares and in servicing 
shareholder accounts. Reimbursement is made through payments at the end of 
each month. The amount of each monthly payment may in no event exceed an 
amount equal to a payment at the annual rate of 0.75 of 1% of the Fund's 
average daily net assets during the month. No interest or other financing 
charges, if any, incurred on any distribution expenses will be reimbursable 
under the Plan. In the case of all expenses other than expenses representing 
a residual to account executives, such amounts shall be determined at the 
beginning of each calendar quarter by the Trustees, including a majority of 
the Independent 12b-1 Trustees. Expenses representing a residual to account 
executives may be reimbursed without prior determination. In the event that 
the Distributor proposes that monies shall be reimbursed for other than such 
expenses, then in making quarterly determinations of the amounts that may be 
expended by the Fund, the Distributor will provide and the Trustees will 
review a quarterly budget of projected distribution expenses to be 
    

                               29           
<PAGE>
incurred on behalf of the Fund, together with a report explaining the 
purposes and anticipated benefits of incurring such expenses. The Trustees 
will determine which particular expenses, and the portions thereof, that may 
be borne by the Fund, and in making such a determination shall consider the 
scope of the Distributor's commitment to promoting the distribution of the 
Fund's shares. 

   
   The Distributor has informed the Fund that a portion of the fees payable 
by the Fund each year pursuant to the Plan equal to 0.25% of the Fund's 
average daily net assets is characterized as a "service fee" under the Rules 
of the Association of the National Association of Securities Dealers (of 
which the Distributor is a member). Such portion of the fee is a payment made 
for personal service and/or the maintenance of shareholder accounts. The 
remaining portion of the Plan fees payable by the Fund is characterized as an 
"asset-based sales charge" as defined in the aforementioned Rules of the 
Association. 

   DWR's account executives are credited with an annual residual commission, 
currently a gross residual of up to 0.75% of the current value of the 
respective accounts for which they are the account executives or dealers of 
record. The residual is a charge which reflects residual commissions paid by 
DWR to its account executives and expenses of DWR and its affiliates 
associated with the servicing of shareholders' accounts, including the 
expenses of operating branch offices in connection with the servicing of 
shareholders' accounts, which expenses include lease costs, the salaries and 
employee benefits of operations and sales support personnel, utility costs, 
communications costs and the costs of stationery and supplies and other 
expenses relating to branch office servicing of shareholder accounts. The 
portion of the annual residual commission allocated to servicing of 
shareholder accounts does not exceed 0.25% of the average annual net asset 
value of shares of accounts for which he or she is account executive of 
record. 
    

   Under the Plan, the Distributor uses its best efforts in rendering 
services to the Fund, but in the absence of willful misfeasance, bad faith, 
gross negligence or reckless disregard of its obligations, the Distributor is 
not liable to the Fund or any of its shareholders for any error of judgment 
or mistake of law or for any act or omission or for any losses sustained by 
the Fund or its shareholders. 

   
   The Fund accrued $1,978,311 to the Distributor, pursuant to the Plan, for 
the fiscal year ended October 31, 1997. This amount represents an annual rate 
of 0.73 of 1% of the Fund's average daily net assets for the fiscal period. 
Based upon the total amounts spent by the Distributor during the period, it 
is estimated that the amount paid by the Fund to the Distributor for 
distribution was spent in approximately the following ways: (i) 
advertising--$-0-; (ii) printing and mailing prospectuses to other than 
current shareholders--$-0-; (iii) compensation to underwriters--$-0-; (iv) 
compensation to dealers--$-0-; (v) compensation to sales personnel--$-0-; and 
(vi) other, which includes payments to DWR for expenses substantially all of 
which relate to compensation of sales personnel (including compensation for 
servicing shareholder accounts and associated overhead expenses)--$1,978,311. 

   The Plan remained in effect until April 30, 1993, and under its terms will 
continue from year to year thereafter, provided such continuance is approved 
annually by a vote of the Trustees, including a majority of the Independent 
12b-1 Trustees. At their meeting held April 24, 1997, the Trustees, including 
a majority of the Independent 12b-1 Trustees, approved the continuance of the 
Plan until April 30, 1998. Any amendment to increase materially the maximum 
amount authorized to be spent under the Plan must be approved by the 
shareholders of the Fund, and all material amendments to the Plan must be 
approved by the Trustees in the manner described above. At their meeting held 
on July 23, 1997, the Trustees of the Fund, including all of the Independent 
12b-1 Trustees, approved amendments to the Plan to change the provisions 
regarding quarterly budgets. The Plan may be terminated at any time, without 
payment of any penalty, by vote of a majority of the Independent Trustees or 
by a vote of the holders of a majority of the outstanding voting securities 
of the Fund (as defined in the Act) on not more than thirty days' written 
notice to any other party to the Plan. So long as the Plan is in effect, the 
selection or nomination of the Independent Trustees is committed to the 
discretion of the Independent 12b-1 Trustees. 
    

   Under the Plan, the Distributor provides the Fund, for review by the 
Trustees, and the Trustees review, promptly after the end of each calendar 
quarter, a written report regarding the distribution expenses incurred on 
behalf of the Fund during such calendar quarter, which report includes (1) an 
itemization of the types of expenses and the purposes therefor; (2) the 
amounts of such expenses; and (3) a description of the benefits derived by 
the Fund. In the Trustees' quarterly review of the Plan they consider its 
continued appropriateness and the level of compensation provided therein. 

                               30           
<PAGE>
   No interested person of the Fund nor any Trustee of the Fund who is not an 
interested person of the Fund, as defined in the Act, has any direct or 
indirect financial interest in the operation of the Plan except to the extent 
that DWR, the Distributor, the Manager or InterCapital or certain of its 
employees may be deemed to have such an interest as a result of benefits 
derived from the successful operation of the Plan or as a result of receiving 
a portion of the amounts expended thereunder by the Fund. 

DETERMINATION OF NET ASSET VALUE 

   As stated in the Prospectus, short-term debt securities with remaining 
maturities of sixty days or less at the time of purchase are valued at 
amortized cost, unless the Trustees determine such does not reflect the 
securities' market value, in which case these securities will be valued at 
their fair value as determined by the Trustees. Other short-term debt 
securities will be valued on a mark-to-market basis until such time as they 
reach a remaining maturity of sixty days, whereupon they will be valued at 
amortized cost using their value on the 61st day unless the Trustees 
determine such does not reflect the securities' market value, in which case 
these securities will be valued at their fair value as determined by the 
Trustees. Listed options are valued at the latest sale price on the exchange 
on which they are listed unless no sales of such options have taken place 
that day, in which case they will be valued at the mean between their latest 
bid and asked prices. Unlisted options are valued at the mean between their 
latest bid and asked prices. Futures are valued at the latest sale price on 
the commodities exchange on which they trade unless the Trustees determine 
that such price does not reflect their market value, in which case they will 
be valued at their fair value as determined by the Trustees. All other 
securities and other assets are valued at their fair value as determined in 
good faith under procedures established by and under the supervision of the 
Trustees. 

   
   As discussed in the Prospectus, the net asset value per share of the Fund 
is determined at 4:00 p.m., New York time (or, on days when the New York 
Stock Exchange closes prior to 4:00 p.m., at such earlier time), on each day 
the New York Stock Exchange is open, by taking the value of all the assets of 
the Fund, subtracting all liabilities, dividing by the number of shares 
outstanding and adjusting the result to the nearest cent. The New York Stock 
Exchange currently observes the following holidays: New Year's Day; Reverend 
Dr. Martin Luther King, Jr. Day; Presidents' Day; Good Friday; Memorial Day; 
Independence Day; Labor Day; Thanksgiving Day and Christmas Day. 
    

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

   Shareholder Investment Account. Upon purchase of shares of the Fund, a 
Shareholder Investment Account is opened for the investor on the books of the 
Fund, maintained by Dean Witter Trust Company (the "Transfer Agent"), in full 
and fractional shares of the Fund (rounded to the nearest 1/100 of a share). 
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. No certificates will be issued for fractional shares or to 
shareholders who have elected the Systematic Withdrawal Plan for withdrawing 
cash from their accounts. Whenever a shareholder instituted transaction takes 
place in the Shareholder Investment Account, the shareholder will be mailed a 
confirmation of the transaction from the Fund or from DWR or another selected 
broker-dealer. 

   
   Automatic Investment of Dividends and Distributions. All dividends and 
capital gains distributions are automatically paid in full and fractional 
shares of the Fund, unless the shareholder requests that they be paid in 
cash. Each purchase of shares of the Fund is made upon the condition that the 
Transfer Agent is thereby automatically appointed as agent of the investor to 
receive all dividends and capital gains distributions on shares owned by the 
investor. Such dividends and distributions will be paid in shares of the Fund 
(or in cash if the shareholder so requests) at the net asset value per share 
as of the close of business on the record date. At any time an investor may 
request the Transfer Agent in writing to have subsequent dividends and/or 
capital gains distributions paid in cash rather than shares. To assure 
sufficient time to process the change, such request should be received by the 
Transfer Agent at least five (5) business days prior to the record date for 
which it commences to take effect. In case of recently purchased shares for 
which registration instructions have not been received on the record date, 
cash payments will be made to DWR or other selected broker-dealer, and will 
be forwarded to the shareholder, upon the receipt of proper instructions. It 
has been and remains the Fund's policy and practice that, if checks for 
dividends or distributions paid in cash remain uncashed, no interest will 
accrue on amounts represented by such uncashed checks. 
    

                               31           
<PAGE>
   
   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 or following 
redemption of shares of a Dean Witter money market fund, on a semi-monthly, 
monthly or quarterly basis, to the Transfer Agent for investment in shares of 
the Fund. Shares purchased through EasyInvest will be added to the 
shareholder's existing account at the net asset value calculated the same 
business day the transfer of funds is effected. Shares of Dean Witter money 
market funds redeemed in connection with EasyInvest are redeemed on the 
business day preceding the transfer of funds. 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 Distributions Received in Cash. As discussed in the 
Prospectus, any shareholder who receives a cash payment representing a 
dividend or capital gains distribution may invest such dividend or 
distribution at net asset value (without sales charge) by returning the check 
or the proceeds to the Transfer Agent within 30 days after the payment date. 
If the shareholder returns the proceeds of a dividend or distribution, such 
funds must be accompanied by a signed statement indicating that the proceeds 
constitute a dividend or distribution to be invested. Such investment will be 
made at the net asset value per share next determined after receipt of the 
check or the proceeds by the Transfer Agent. 

   Direct Investments through Transfer Agent. As discussed in the Prospectus, 
a shareholder may make additional investments in Fund shares at any time by 
sending a check in any amount, not less than $100, payable to TCW/DW North 
American Government Income Trust, directly to the Transfer Agent. Such 
amounts will be applied to the purchase of Fund shares at the net asset value 
per share next computed after receipt of the check or purchase payment by the 
Transfer Agent. The shares so purchased will be credited to the investor's 
account. 

   Targeted Dividends (Service Mark). In states where it is legally 
permissible to do so, shareholders may also have all income dividends and 
capital gains distributions automatically invested in shares of an open-end 
TCW/DW Fund other than TCW/DW North American Government Income Trust. Such 
investment will be made as described above for automatic investment in shares 
of the Fund, at the net asset value per share of the selected TCW/DW 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 TCW/DW 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 TCW/DW Fund targeted to receive investments from 
dividends at the time they enter the Targeted Dividends program. Investors 
should review the prospectus of the targeted TCW/DW Fund before entering the 
program. 

   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 the then 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. The shares will be 
redeemed at their net asset value determined, at the shareholder's option, on 
the tenth or twenty-fifth day (or next following business day) of the 
relevant month or quarter and normally a check for the proceeds will be 
mailed by the Transfer Agent, or amounts credited to a shareholder's DWR or 
other selected broker-dealer brokerage account, within five business days 
after the date of redemption. 

   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. 

   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. 

   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 

                               32           
<PAGE>
shares will be redeemed at their net asset value determined, at the 
shareholder's option, on the tenth or twenty-fifth day (or next following 
business day) of the relevant month or quarter and normally a check for the 
proceeds will be mailed by the Transfer Agent within five business days after 
the date of redemption. The Withdrawal Plan may be terminated at any time by 
the Fund. 

   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. The shareholder's signature on such 
notification 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). 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 "Repurchases and Redemptions" in 
the Prospectus) at any time. 

EXCHANGE PRIVILEGE 

   
   As discussed in the Prospectus under the caption "Exchange Privilege," an 
Exchange Privilege exists whereby investors who have purchased shares of any 
of the TCW/DW Funds that are multiple class funds ("TCW/DW Multi-Class 
Funds") will be permitted, after the shares of the fund acquired by purchase 
(not by exchange or dividend reinvestment) have been held for thirty days, to 
redeem all or part of their shares in that fund, have the proceeds invested 
in shares of the Fund and in shares of five money market funds for which 
InterCapital serves as investment manager: 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, or Dean Witter U.S. Government Money Market Trust (these six funds, 
including the Fund, are hereinafter collectively referred to as "Exchange 
Funds"). There is no waiting period for exchanges of shares acquired by 
exchange or dividend reinvestment. Shares of the Exchange Funds received in 
an exchange for shares of a TCW/DW Multi-Class Fund may be redeemed or 
exchanged only for shares of the corresponding Class of a TCW/DW Multi-Class 
Fund or for shares of one of the other Exchange Funds. Ultimately, any 
applicable contingent deferred sales charge ("CDSC") will have to be paid 
upon redemption of shares originally purchased from a Class of a TCW/DW 
Multi-Class Fund that imposes a CDSC. 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.) 

   
   When shares of a TCW/DW Multi-Class Fund are exchanged for shares of an 
Exchange Fund, the exchange is executed at no charge to the shareholder, 
without the imposition of the CDSC at the time of the exchange. During the 
period of time the shareholder remains in the Exchange Fund, (calculated from 
the last day of the month in which the Exchange Fund shares were acquired), 
the holding period or "year since purchase payment made" is frozen. When 
shares are redeemed out of the Exchange Fund, they will be subject to a CDSC 
which would be based upon the period of time the shareholder held shares in a 
TCW/DW Multi-Class Fund. However, in the case of shares exchanged into an 
Exchange Fund, upon redemption of shares which results in a CDSC being 
imposed, a credit (not to exceed the amount of the CDSC) will be given in an 
amount equal to the Exchange Fund 12b-1 distribution fees which are 
attributable to those shares. Shareholders acquiring shares of an Exchange 
Fund pursuant to this exchange privilege may exchange those shares back into 
a TCW/DW Multi-Class Fund from the Exchange Fund, with no CDSC being imposed 
on such exchange. The holding period previously frozen when shares were first 
exchanged for shares of the Exchange Fund resumes on the last day of the 
month in which shares of a TCW/DW Multi-Class Fund are reacquired. Thus, a 
CDSC is imposed only upon an ultimate redemption, based upon the time 
(calculated as described above) the shareholder was invested in a TCW/DW 
Multi-Class Fund. 
    

                               33           
<PAGE>
   
   When shares initially purchased in a TCW/DW Multi-Class Fund are exchanged 
for shares of a TCW/DW Multi-Class Fund or shares of an Exchange Fund, the 
date of purchase of the shares of the fund exchanged into, for purposes of 
the CDSC upon redemption, will be the last day of the month in which the 
shares being exchanged were originally purchased. In allocating the purchase 
payments between funds for purposes of the CDSC, the amount which represents 
the current net asset value of shares at the time of the exchange which were 
(i) purchased more than one, three or six years (depending on the CDSC 
applicable to the shares) prior to the exchange and (ii) originally acquired 
through reinvestment of dividends or distributions (all such shares called 
"Free Shares"), will be exchanged first. After an exchange, all dividends 
earned on shares in the Exchange Fund will be considered Free Shares. If the 
exchanged amount exceeds the value of such Free Shares, an exchange is made, 
on a block-by-block basis, of non-Free Shares held for the longest period of 
time. Shares equal to any appreciation in the value of non-Free Shares 
exchanged will be treated as Free Shares, and the amount of the purchase 
payments for the non-Free Shares of the fund exchanged into will be equal to 
the lesser of (a) the purchase payments for, or (b) the current net asset 
value of, the exchanged non-Free Shares. If an exchange between funds would 
result in exchange of only part of a particular block of non-Free Shares, 
then shares equal to any appreciation in the value of the block (up to the 
amount of the exchange) will be treated as Free Shares and exchanged first, 
and the purchase payment for that block will be allocated on a pro-rata basis 
between the non-Free Shares of that block to be retained and the non-Free 
Shares to be exchanged. The prorated amount of such purchase payment 
attributable to the retained non-Free Shares will remain as the purchase 
payment for such shares, and the amount of purchase payment for the exchanged 
non-Free Shares will be equal to the lesser of (a) the prorated amount of the 
purchase payment for, or (b) the current net asset value of those exchanged 
non-Free Shares. Based upon the procedures described in the TCW/DW 
Multi-Class Fund Prospectus under the caption "Purchase of Fund Shares," any 
applicable CDSC will be imposed upon the ultimate redemption of shares of any 
fund, regardless of the number of exchanges since those shares were 
originally purchased. 

   With respect to the redemption or repurchase of shares of the Fund, the 
application of proceeds to the purchase of new shares in the Fund or any 
other of the funds and the general administration of the Exchange Privilege, 
the Transfer Agent acts as agent for the Distributor and for the 
shareholder's selected broker-dealer, if any, in the performance of such 
functions. With respect to exchanges, redemptions or repurchases, the 
Transfer Agent shall be liable for its own negligence and not for the default 
or negligence of its correspondents or for losses in transit. The Fund shall 
not be liable for any default or negligence of the Transfer Agent, the 
Distributor or any selected broker-dealer. 
    

   The Distributor and any selected broker-dealer have authorized and 
appointed the Transfer Agent to act as their agent in connection with the 
application of proceeds of any redemption of Fund shares to the purchase of 
the 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. 

   
   Shares of the Fund acquired pursuant to the Exchange Privilege will be 
held by the Fund's Transfer Agent in an Exchange Privilege account distinct 
from any account of the same shareholder who may have acquired shares of the 
Fund directly. A shareholder of the Fund will not be permitted to make 
additional investments in such Exchange Privilege account, except through the 
exchange of additional shares of the fund in which the shareholder had 
initially invested, and the proceeds of any shares redeemed from such 
Exchange Privilege account may not thereafter be placed back into that 
Exchange Privilege account, except by utilizing the Reinstatement Privilege 
(see "Repurchases and Redemptions--Reinstatement Privilege"). If such a 
shareholder desires to make any additional investments in the Fund, a 
separate account will be maintained for receipt of such investments. The Fund 
will have additional costs for account maintenance if a shareholder has more 
than one account with the Fund. 

   Exchanges are subject to the minimum investment requirement and any other 
conditions imposed by each fund. (The minimum initial investment for the 
Exchange Privilege account of each Class is $5,000 for Dean Witter Liquid 
Asset Fund Inc., Dean Witter Tax-Free Daily Income Trust, Dean Witter 
California Tax-Free Daily Income Trust and Dean Witter New York Municipal 
Money Market Trust, although those funds may, at their discretion, accept 
initial investments of as low as $1,000. The minimum initial investment for 
the Exchange Privilege account of each Class for Dean Witter U.S. Government 
Money Market Trust and all TCW/DW Funds is $1,000.) Upon exchange into a 
money market fund, the shares of that fund will be held in a special Exchange 
    

                               34           
<PAGE>
Privilege Account separately from accounts of those shareholders who have 
acquired their shares directly from that fund. As a result, certain services 
normally available to shareholders of money market funds, including the check 
writing feature, will not be available for funds held in that account. 

   
   The Fund, each of the other TCW/DW Funds and each of the money market 
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 any of the TCW/DW Funds 
or the money market funds, upon such notice as may be required by applicable 
regulatory agencies (presently sixty days' prior written notice for 
termination or material revision), provided that six months' prior written 
notice of termination will be given to the shareholders who hold shares of 
the Exchange Funds pursuant to this Exchange Privilege, and provided further 
that the Exchange Privilege may be terminated or materially revised 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 Fund's Exchange Privilege, 
shareholders should contact their DWR or other selected broker-dealer account 
executive or the Transfer Agent. 

REPURCHASES AND REDEMPTIONS 
- ----------------------------------------------------------------------------- 

   
   Payment for Shares Repurchased or Redeemed. As discussed in the 
Prospectus, payment for shares presented for repurchase or redemption will be 
ordinarily 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 (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 to fairly 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. If the shares to be redeemed have recently been purchased 
by check and the check has not yet cleared, payment of redemption proceeds 
may be delayed until the check has cleared. It has been and remains the 
Fund's policy and practice that, if checks for dividends or distributions 
paid in cash remain uncashed, no interest will accrue on amounts represented 
by such uncashed checks. 
    

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

   The Fund intends to continue to qualify and elect to be treated as a 
regulated investment company for each taxable year under the Internal Revenue 
Code of 1986, as amended (the "Code"). To so qualify, the Fund must meet 
certain requirements as to the nature of its income and the nature of its 
assets. 

   As a regulated investment company, the Fund will not be subject to United 
States federal income tax on its income that it distributes to its 
shareholders, provided that an amount equal to at least 90% of its investment 
company taxable income (i.e., 90% of its taxable income minus the excess, if 
any, of its net realized long-term capital gains over its net realized 
short-term capital losses including any capital loss carryovers), plus or 
minus certain other adjustments as specified in section 852 of the Code) for 
the taxable year is distributed, but will be subject to tax at regular 
corporate rates on any income or gains that it does not distribute. 
Furthermore, the Fund will be subject to a United States corporate income tax 
with respect to such distributed amounts in any year that it fails to qualify 
as a regulated investment company or fails to meet this distribution 
requirement. 

   Gains or losses on the Fund's transactions in certain listed options on 
securities and on futures and options on futures traded on U.S. exchanges 
generally are treated as 60% long-term gain or loss and 40% short-term gain 
or loss. When the Fund engages in options and futures transactions, various 
tax regulations applicable to the Fund may have the effect of causing the 
Fund to recognize a gain or loss for tax purposes before that gain or loss is 

                               35           
<PAGE>
realized, or to defer recognition of a realized loss for tax purposes. 
Recognition, for tax purposes, of an unrealized loss may result in a lesser 
amount of the Fund's realized net gains being available for distribution. 

   As a regulated investment company, the Fund is subject to the requirement 
that less than 30% of its gross income be derived from the sale of certain 
investments held for less than three months. This requirement may limit the 
Fund's ability to engage in options and futures transactions and to engage in 
a large number of short-term transactions. 

   As discussed in the Prospectus, the Fund will determine either to 
distribute or to retain all or part of any net long-term capital gains in any 
year for reinvestment. If any such gains are retained, the Fund expects to 
designate such retained amounts as undistributed capital gains in a notice to 
its shareholders who (a) will be required to include in income for United 
States federal income tax purposes, as long-term capital gains, their 
proportionate shares of the undistributed amount, (b) will be entitled to 
credit their proportionate shares of the 35% tax paid by the Fund on the 
undistributed amount against their United States federal income tax 
liabilities, if any, and to claim refunds to the extent their credits exceed 
their liabilities, if any, and (c) will be entitled to increase their tax 
basis, for United States federal income tax purposes, in their shares by an 
amount equal to 65% of the amount of undistributed capital gains included in 
the shareholder's income. 

   The Code imposes a 4% nondeductible excise tax on the Fund to the extent 
the Fund does not distribute by the end of any calendar year at least 98% of 
its net investment income for that year and 98% of the net amount of its 
capital gains (both long-and short-term) for the one-year period ending, as a 
general rule, on October 31 of that year. For this purpose, however, any 
income or gain retained by the Fund that is subject to corporate income tax 
will be considered to have been distributed by year-end. The Fund anticipates 
that it will pay such dividends and will make such distributions as are 
necessary in order to avoid the application of this tax. 

   
   Gains or losses on sales of securities by the Fund will generally 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 generally short-term gains or losses. 
Treasury intends to issue regulations to permit shareholders to take into 
account their proportionate share of the Fund's capital gains distributions 
that will be subject to a reduced rate under the Taxpayer Relief Act of 1997. 
The Taxpayer Relief Act reduced the maximum tax on long-term capital gains 
from 28% to 20%; however, it also lengthened the required holding period to 
obtain this lower rate from more than 12 months to more than 18 months. These 
lower rates do not apply to collectibles and certain other assets. 
Additionally, the maximum capital gain rate for assets that are held more 
than 5 years and that are acquired after December 31, 2000 is 18%. 
    

   The Fund may invest in securities having original issue discount which may 
generate income in excess of the cash received by the Fund. Consequently, the 
Fund may be required to borrow or to liquidate securities in order to make 
distributions. 

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

   Any loss realized by shareholders upon a redemption of shares within six 
months of the date of their purchase will be treated as a long-term capital 
loss to the extent of any distributions of net long-term capital gains during 
the six-month period. 

   Dividends, interest and capital gains received by the Fund may give rise 
to withholding and other taxes imposed by foreign countries. Tax treaties 
between certain countries and the United States may reduce or eliminate such 
taxes. Investors may be entitled to claim United States foreign tax credits 
or deductions with respect to such taxes, subject to certain provisions and 
limitations contained in the Code. If more than 50% of the Fund's total 
assets at the close of its fiscal year consist of securities of foreign 
corporations, the Fund would be eligible and would determine whether or not 
to file an election with the Internal Revenue Service pursuant to which 

                               36           
<PAGE>
   
shareholders of the Fund will be required to include their respective pro 
rata portions of such withholding taxes in their United States income tax 
returns as gross income, treat such respective pro rata portions as taxes 
paid by them, and deduct such respective pro rata portions in computing their 
taxable income or, alternatively, use them as foreign tax credits against 
their United States income taxes. The Fund will report annually to its 
shareholders the amount per share of such withholding. The Taxpayer Relief 
Act of 1997 mandates a holding period requirement for claiming a foreign tax 
credit with respect to dividends. The foreign tax credit normally available 
with respect to a dividend from a corporation (or a Fund that has made an 
election under Section 853), is disallowed if the shareholder has not held 
the stock for, in general, 16 days in the case of common stock (46 days in 
the case of preferred stock) during the 30-day (90-day) period beginning 15 
days (46 days) before the ex-date of the dividend with respect to which the 
foreign tax is paid. The holding period requirement applies to shareholders 
of the Fund as well as the Fund itself. 
    

   Special Rules for Certain Foreign Currency Transactions. In general, gains 
from foreign currencies and from foreign currency options, foreign currency 
futures and forward foreign exchange contracts relating to investments in 
stock, securities or foreign currencies are currently considered to be 
qualifying income for purposes of determining whether the Fund qualifies as a 
regulated investment company. It is currently unclear, however, who will be 
treated as the issuer of certain foreign currency instruments or how foreign 
currency options, futures, or forward foreign currency contracts will be 
valued for purposes of the regulated investment company diversification 
requirements applicable to the Fund. The Fund may request a private letter 
ruling from the Internal Revenue Service on some or all of these issues. 

   Under Code Section 988, special rules are provided for certain 
transactions in a foreign currency other than the taxpayer's functional 
currency (i.e., unless certain special rules apply, currencies other than the 
U.S. dollar). In general, foreign currency gains or losses from forward 
contracts, from futures contracts that are not "regulated futures contracts", 
and from unlisted options will be treated as ordinary income or loss under 
Code Section 988. Also, certain foreign exchange gains or losses derived with 
respect to foreign fixed-income securities are also subject to Section 988 
treatment. In general, therefore, Code Section 988 gains or losses will 
increase or decrease the amount of the Fund's investment company taxable 
income available to be distributed to shareholders as ordinary income, rather 
than increasing or decreasing the amount of the Fund's net capital gain. 
Additionally, if Code Section 988 losses exceed other investment company 
taxable income during a taxable year, the Fund may not be able to make any 
ordinary dividend distributions and distributions paid during the year may be 
characterized for tax purposes as a return of capital. 

   Exchange control regulations may restrict repatriations of investment 
income and capital or the proceeds of securities sales by foreign investors 
such as the Fund and may limit the Fund's ability to pay sufficient dividends 
and to make sufficient distributions to satisfy the 90% and excise tax 
distribution requirements. 

   The Fund's transactions, if any, in foreign currencies, forward contracts, 
options and futures contracts (including options and futures contracts on 
foreign currencies) may be subject to special provisions of the Code that, 
among other things, may affect the character of gains and losses realized by 
the Fund (i.e., may affect whether gains or losses are ordinary or capital), 
accelerate recognition of income to the Fund and defer Fund losses. These 
rules could therefore affect the character, amount and timing of 
distributions to shareholders. These rules also (a) could require the Fund to 
mark-to-market certain types of the positions in its portfolio (i.e., treat 
them as they were closed out) and (b) may cause the Fund to recognize income 
without receiving cash with which to pay dividends or make distributions in 
amounts necessary to satisfy the distribution requirements for avoiding 
income and excise taxes. 

   
   If the Fund invests in an entity which is classified as a "passive foreign 
investment company" ("PFIC") for U.S. tax purposes, the application of 
certain technical tax provisions applying to such companies could result in 
the imposition of federal income tax with respect to such investments at the 
Fund level which could not be eliminated by distributions to shareholders. 
The Taxpayer Relief Act of 1997 establishes a mark-to-market regime which 
allows taxpayers investing in PFICs to avoid most, if not all of the 
difficulties posed by the PFIC rules. In any event, it is not anticipated 
that any taxes on the Fund with respect to investments in PFIC's would be 
significant. 
    

   Distributions in excess of the Fund's current and accumulated earnings and 
profits will, as to each shareholder, be treated as a tax-free return of 
capital, to the extent of a shareholder's basis in his shares of the Fund, 
and as a capital gain thereafter (if the shareholder held his or her shares 
of the Fund as capital assets). 

                               37           
<PAGE>
   Shareholders receiving dividends or distributions in the form of 
additional Fund shares should be treated for United States federal income tax 
purposes as receiving a distribution in an amount equal to the amount of 
money that the shareholders receiving cash dividends or distributions will 
receive, and should have a cost basis in the shares received equal to such 
amount. 

   Any loss realized on the redemption by a shareholder of his shares will be 
disallowed to the extent the shares disposed of are replaced, including 
replacement through the reinvesting of dividends and capital gains 
distributions in the Fund, within a period (of 61 days) beginning 30 days 
before and ending 30 days after the disposition of the shares. In such a 
case, the basis of the shares acquired will be increased to reflect the 
disallowed loss. Any loss realized by a shareholder on the sale of a Fund 
share held by the shareholder for six months or less will be treated for 
United States income tax purposes as a long-term capital loss to the extent 
of any distributions or deemed distributions of long-term capital gains 
received by the shareholder with respect to such share. 

   Distributions may also be subject to state, local and foreign taxes 
depending on each shareholder's particular situation. 

   The foregoing discussion is a general summary of certain of the current 
Federal income tax laws regarding the Fund and investors. The discussion does 
not purport to deal with all of the Federal income tax consequences 
applicable to the Fund, or to all categories of investors, some of which may 
be subject to special rules. Investors should consult their own tax advisors 
regarding the tax consequences to them of investments in shares. 

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

   
   As discussed in the Prospectus, from time to time the Fund may quote its 
"yield" and/or its "total return" in advertisements and sales literature. 
Yield is calculated for any 30-day period as follows: the amount of interest 
and/or dividend income for each security in the Fund's portfolio is 
determined in accordance with regulatory requirements; the total for the 
entire portfolio constitutes the Fund's gross income for the period. Expenses 
accrued during the period are subtracted to arrive at "net investment 
income." The resulting amount is divided by the product of the net asset 
value per share on the last day of the period multiplied by the average 
number of Fund shares outstanding during the period that were entitled to 
dividends. This amount is added to 1 and raised to the sixth power. 1 is then 
subtracted from the result and the difference is multiplied by 2 to arrive at 
the annualized yield. The Fund's yield for the 30-day period ended October 
31, 1997 was 5.43%. 

   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 for the Fund for the 1 and 
5 year periods ended October 31, 1997 and for the period from July 31, 1992 
(commencement of operations) through October 31, 1997, were 7.80%, 3.88% and 
3.95%, 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. 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 by the initial $1,000 investment and subtracting 1 
from the result. The Fund's total returns for the 1 and 5 year periods ended 
October 31, 1997 and for the period from July 31, 1992 through October 31, 
1997, were 7.80%, 20.98% and 22.53%, respectively. 

   The Fund may also advertise the growth of hypothetical investments of 
$10,000, $50,000 and $100,000 in shares of the Fund by adding 1 to the Fund's 
aggregate total return and multiplying by $10,000, $50,000 or $100,000, as 
the case may be. Investments of $10,000, $50,000 and $100,000 in the Fund at 
inception would have grown to $12,253, $61,265 and $122,530, respectively, at 
October 31, 1997.

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

DESCRIPTION OF SHARES 
- ----------------------------------------------------------------------------- 

   The shareholders of the Fund are entitled to a full vote for each full 
share held. The Trustees have been elected by DWR as the then sole 
shareholder of the Fund on May 11, 1992, or, in the case of Messrs. Schroeder 
and Stern, by the other Trustees of the Fund on April 20, 1995. The Trustees 
themselves have the power to alter the number and the terms of office of the 
Trustees, and they may at any time lengthen their own terms or make their 
terms of unlimited duration and appoint their own successors, provided that 
always at least a majority of the Trustees has been elected by the 
shareholders of the Fund. Under certain circumstances the Trustees may be 
removed by action of the Trustees. The shareholders also have the right to 
remove the Trustees following a meeting called for that purpose requested in 
writing by the record holders of not less than ten percent of the Fund's 
outstanding shares. The voting rights of shareholders are not cumulative, so 
that holders of more than 50 percent of the shares voting can, if they 
choose, elect all Trustees being selected, while the holders of the remaining 
shares would be unable to elect any Trustees. 

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

   The Declaration of Trust provides that no Trustee, officer, employee or 
agent of the Fund is liable to the Fund or to a shareholder, nor is any 
Trustee, officer, employee or agent liable to any third persons in connection 
with the affairs of the Fund, except as such liability may arise from his 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's property for satisfaction of claims arising in connection with the 
affairs of the Fund. With the exceptions stated, the Declaration of Trust 
provides that a Trustee, officer, employee or agent is entitled to be 
indemnified against all liabilities in connection with the affairs of the 
Fund. 

   The Fund is authorized to issue an unlimited number of shares of 
beneficial interest. The Fund shall be of unlimited duration subject to the 
provisions in the Declaration of Trust concerning termination by action of 
the shareholders.

TCW/DW NORTH AMERICAN GOVERNMENT INCOME TRUST 
NOTES TO FINANCIAL STATEMENTS October 31, 1997 

   
1. ORGANIZATION AND ACCOUNTING POLICIES 

TCW/DW North American Government Income Trust (the "Fund") is registered 
under the Investment Company Act of 1940, as amended (the "Act"), as a 
non-diversified, open-end management investment company. The Fund's 
investment objective is to earn a high level of income while maintaining 
relatively low volatility of principal. The Fund was organized as a 
Massachusetts business trust on February 19, 1992 and commenced operations on 
July 31, 1992. 

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

The following is a summary of significant accounting policies: 

A. VALUATION OF INVESTMENTS -- (1) portfolio securities for which 
over-the-counter market quotations are readily available are valued at the 
latest available bid price prior to the time of valuation; (2) when market 
quotations are not readily available, including circumstances under which it 
is determined by TCW Funds Management, Inc. (the "Adviser") that sale or bid 
prices are not reflective of a security's market value, portfolio securities 
are valued at their fair value as determined in good faith under procedures 
established by and under the general supervision of the Trustees (valuation 
of debt securities for which market quotations are not readily available may 
be based upon current market prices of securities which are comparable in 
coupon, rating and maturity or an appropriate matrix utilizing similar 
factors); and (3) 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 based on the 
respective life of the securities. Interest income is accrued daily. 

C. FOREIGN CURRENCY TRANSLATION -- The books and records of the Fund are 
maintained in U.S. dollars as follows: (1) the foreign currency market value 
of investment securities, other assets and liabilities and forward foreign 
currency contracts are translated at the exchange rates prevailing at the end 
of the period; and (2) purchases, sales, income and expenses are translated 
at the exchange rates prevailing on the respective dates of such 
transactions. The resultant exchange gains and losses are included in the

Statement of Operations as realized and unrealized gain/loss on foreign 
exchange transactions. Pursuant to U.S. Federal income tax regulations, 
certain foreign exchange gains/losses included in realized and unrealized 
gain/loss are included in or are a reduction of ordinary income for federal 
income tax purposes. The Fund does not isolate that portion of the results of 
operations arising as a result of changes in the foreign exchange rates from 
the changes in the market prices of the securities. 

D. FORWARD FOREIGN CURRENCY CONTRACTS -- The Fund may enter into forward 
foreign currency contracts which are valued daily at the appropriate exchange 
rates. The resultant unrealized exchange gains and losses are included in the 
Statement of Operations as unrealized foreign currency gain or loss. The Fund 
records realized gains or losses on delivery of the currency or at the time 
the forward contract is extinguished (compensated) by entering into a closing 
transaction prior to delivery. 

E. DOLLAR ROLLS -- The Fund may enter into dollar rolls in which the Fund 
sells securities for delivery and simultaneously contracts to repurchase 
substantially similar securities at the current sales price on a specified 
future date. The difference between the current sales price and the lower 
forward price for the future purchase (often referred to as the "drop") is 
amortized over the life of the dollar roll. 

F. FEDERAL INCOME TAX STATUS -- It is the Fund's policy to comply with the 
requirements of the Internal Revenue Code applicable to regulated investment 
companies and to distribute all of its taxable income to its shareholders. 
Accordingly, no federal income tax provision is required. 

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

H. ORGANIZATIONAL EXPENSES -- Dean Witter InterCapital Inc., an affiliate of 
Dean Witter Services Company Inc. (the "Manager"), paid the organizational 
expenses of the Fund in the amount of approximately $200,000 and was 
reimbursed for the full amount thereof. Such expenses have been deferred and 
were fully amortized as of July 30, 1997. 

2. MANAGEMENT AGREEMENT 

Pursuant to a Management Agreement, the Fund pays the Manager a management 
fee, accrued daily and payable monthly, by applying the following annual 
rates to the net assets of the Fund determined as of the close of each 
business day: 0.39% to the portion of daily net assets not exceeding $3 
billion and 0.36% to the portion of daily net assets exceeding $3 billion. 

Under the terms of the Agreement, the 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 Manager. The Manager also bears the cost of telephone 
services, heat, light, power and other utilities provided to the Fund. 

3. INVESTMENT ADVISORY AGREEMENT 

Pursuant to an Investment Advisory Agreement with the Adviser, the Fund pays 
an advisory fee, calculated daily and payable monthly, by applying the 
following annual rates to the net assets of the Fund determined as of the 
close of each business day: 0.26% to the portion of average daily net assets 
not exceeding $3 billion and 0.24% to the portion of average daily net assets 
exceeding $3 billion. 

Under the terms of the Agreement, the Fund has retained the Adviser to invest 
the Fund's assets, including placing orders for the purchase and sale of 
portfolio securities. The Adviser 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. In addition, the 
Adviser pays the salaries of all personnel, including officers of the Fund, 
who are employees of the Adviser. 

4. PLAN OF DISTRIBUTION 

Dean Witter Distributors Inc. (the "Distributor"), an affiliate of the 
Manager, is the distributor of the Fund's shares and, in accordance with a 
Plan of Distribution (the "Plan") pursuant to Rule 12b-1 under the Act, 
finances certain expenses in connection with the distribution of shares of 
the Fund.

TCW/DW NORTH AMERICAN GOVERNMENT INCOME TRUST 
NOTES TO FINANCIAL STATEMENTS October 31, 1997, continued 

   
Under the Plan, the Distributor bears the expense of all promotional and 
distribution related activities on behalf of the Fund, except for expenses 
that the Trustees determine to reimburse, as described below. The following 
activities and services may be provided by the Distributor, Dean Witter 
Reynolds Inc. ("DWR"), an affiliate of the Distributor and Investment 
Manager, its affiliates or any other selected broker-dealer under the Plan: 
(1) compensation to, and expenses of, account executives of DWR and others, 
including overhead and telephone expenses; (2) sales incentives and bonuses 
to sales representatives and to marketing personnel in connection with 
promoting sales of the Fund's shares; (3) expenses incurred in connection 
with promoting sales of the Fund's shares; (4) preparing and distributing 
sales literature; and (5) providing advertising and promotional activities, 
including direct mail solicitation and television, radio, newspaper, magazine 
and other media advertisements. 

The Fund is authorized to reimburse the Distributor for specific expenses the 
Distributor incurs or plans to incur in promoting the distribution of the 
Fund's shares. The amount of each monthly reimbursement payment may in no 
event exceed an amount equal to a payment at the annual rate of 0.75% of the 
Fund's average daily net assets during the month. Expenses incurred pursuant 
to the Plan in any fiscal year in excess of 0.75% of the Fund's average daily 
net assets will not be reimbursed by the Fund through payments accrued in any 
subsequent fiscal year. For the year ended October 31, 1997, the distribution 
fee was accrued at the annual rate of 0.73%. 

5. SECURITY TRANSACTIONS AND TRANSACTIONS WITH AFFILIATES

7.  FEDERAL INCOME TAX STATUS 

At October 31, 1997, the Fund had an approximate net capital loss carryover 
of $230,494,000, which may be used to offset future capital gains to the 
extent provided by regulations, which is available through October 31 of the 
following years:

8. REVERSE REPURCHASE AND DOLLAR ROLL AGREEMENTS 

Reverse repurchase and dollar roll agreements involve the risk that the 
market value of the securities the Fund is obligated to repurchase under the 
agreement may decline below the repurchase price. In the event the buyer of 
securities under a reverse repurchase or dollar roll agreement files for 
bankruptcy or becomes insolvent, the Fund's use of proceeds of the agreement 
may be restricted pending a determination by the other party, its trustee or 
receiver, whether to enforce the Fund's obligation to repurchase the 
securities. 

Reverse repurchase agreements are collateralized by Fund securities with a 
market value in excess of the Fund's obligation under the contract. 

9. PURPOSES OF AND RISKS RELATING TO CERTAIN FINANCIAL INSTRUMENTS 

The Fund may enter into forward foreign currency contracts ("forward 
contracts") to facilitate settlement of foreign currency denominated 
portfolio transactions or to manage foreign currency exposure associated with 
foreign currency denominated securities. 
    

                               49           
<PAGE>
TCW/DW NORTH AMERICAN GOVERNMENT INCOME TRUST 
NOTES TO FINANCIAL STATEMENTS October 31, 1997, continued 

   
Forward contracts involve elements of market risk in excess of the amounts 
reflected in the Statement of Assets and Liabilities. The Fund bears the risk 
of an unfavorable change in the foreign exchange rates underlying the forward 
contracts. Risks may also arise upon entering into these contracts from the 
potential inability of the counterparties to meet the terms of their 
contracts. 

At October 31, 1997, there were no outstanding forward contracts. 

10. LITIGATION 

Several class action lawsuits, which have been consolidated for pretrial 
purposes, were instituted in 1995 in the United States District Court, in New 
York, against the Fund, some of its Trustees and officers, its underwriter 
and distributor, the Adviser, the Manager, and other defendants, by certain 
shareholders of the Fund. The consolidated amended complaint asserts claims 
under the Securities Act of 1933 and generally alleges that the defendants 
made inadequate and misleading disclosures in the prospectuses for the Fund, 
in particular as such disclosures relate to the nature and risks of the 
Fund's investments in mortgage-backed securities and Mexican securities. The 
plaintiffs also challenge certain fees paid by the Fund as excessive. Damages 
are sought in an unspecified amount. All defendants have moved to dismiss the 
consolidated amended complaint, and on May 8, 1996 the motions to dismiss 
were denied. The defendants moved for reargument and on August 28, 1996 the 
Court issued a second opinion which granted the motion to dismiss in part. On 
December 4, 1996 the defendants filed a renewed motion to dismiss which was 
denied by the Court on November 20, 1997. The Court has also certified a 
plaintiff class pursuant to the Federal Rules of Civil Procedure. 

The ultimate outcome of these matters is not presently determinable, and no 
provision has been made in the Fund's financial statements for the effect, if 
any, of such matters.

TCW/DW NORTH AMERICAN GOVERNMENT INCOME TRUST 
REPORT OF INDEPENDENT ACCOUNTANTS 

TO THE SHAREHOLDERS AND TRUSTEES 
OF TCW/DW NORTH AMERICAN GOVERNMENT INCOME 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 TCW/DW North 
American Government Income Trust (the "Fund") at October 31, 1997, the 
results of its operations for the year then ended, the changes in its net 
assets for each of the two years in the period then ended and the financial 
highlights for each of the five years in the period then ended and for the 
period July 31, 1992 (commencement of operations) through October 31, 1992, 
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 October 31, 1997 by correspondence with the 
custodian, provide a reasonable basis for the opinion expressed above.

RATINGS 

MOODY'S INVESTORS SERVICE INC. ("MOODY'S") 

                        FIXED-INCOME SECURITY RATINGS 

Aaa      Fixed-income securities 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       Fixed Income securities 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 fixed-income securities. They 
         are rated lower than the best fixed-income securities 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        Fixed-income securities 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      Fixed-income securities 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 fixed-income securities lack outstanding 
         investment characteristics and in fact have speculative 
         characteristics as well. 

         Fixed-income securities rated Aaa, Aa, A and Baa are considered 
         investment grade. 

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

                           COMMERCIAL PAPER RATINGS 

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

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

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

                        FIXED-INCOME SECURITY RATINGS 

   A Standard & Poor's fixed-income security 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. 

                               53           
<PAGE>
   The ratings are based on current information furnished by the issuer or 
obtained by Standard & Poor's from other sources it considers reliable. The 
ratings are based, in varying degrees, on the following considerations: (1) 
likelihood of default-capacity and willingness of the obligor as to the 
timely payment of interest and repayment of principal in accordance with the 
terms of the obligation; (2) nature of and provisions of the obligation; and 
(3) protection afforded by, and relative position of, the obligation in the 
event of bankruptcy, reorganization or other arrangement under the laws of 
bankruptcy and other laws affecting creditors' rights. 

   Standard & Poor's does not perform an audit in connection with any rating 
and may, on occasion, rely on unaudited financial information. The ratings 
may be changed, suspended or withdrawn as a result of changes in, or 
unavailability of, such information, or for other reasons. 

AAA      Fixed-income securities rated AAA have the highest rating assigned 
         by Standard & Poor's. Capacity to pay interest and repay principal 
         is extremely strong. 

AA       Fixed-income securities rated AA have a very strong capacity to pay 
         interest and repay principal and differs from the highest-rated 
         issues only in small degree. 

A        Fixed-income securities rated A have 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 fixed-income securities in higher-rated 
         categories. 

BBB      Fixed-income securities rated BBB are regarded as having an adequate 
         capacity to pay interest and repay principal. Whereas it normally 
         exhibits adequate protection parameters, adverse economic conditions 
         or changing circumstances are more likely to lead to a weakened 
         capacity to pay interest and repay principal for fixed-income 
         securities in this category than for fixed-income securities in 
         higher-rated categories. 

         Fixed-income securities rated AAA, AA, A and BBB are considered 
         investment grade. 

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. 

                           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. 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 payment is very 
         strong. 

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

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

Item 27.    Indemnification.

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

                                       2
<PAGE>

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 Management or either Co-Advisory Agreements,
none of the Manager, the Advisers or any trustee, officer, employee or agent of
the Registrant shall be liable for any action or failure to act, except in the
case of bad faith, willful misfeasance, gross negligence or reckless disregard
of duties to the Registrant.

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

                 TCW/DW NORTH AMERICAN GOVERNMENT INCOME TRUST
                  AMENDED AND RESTATED AS OF OCTOBER 23, 1997

                                   ARTICLE I
                                  DEFINITIONS

   The terms "Commission," "Declaration," "Distributor," "Investment 
Adviser," "Majority Shareholder Vote," "1940 Act," "Shareholder," "Shares," 
"Transfer Agent," "Trust," "Trust Property," and "Trustees" have the

                                   ARTICLE II
                                    OFFICES

   SECTION 2.1. Principal Office. Until changed by the Trustees, the 
principal office of the Trust in the Commonwealth of Massachusetts shall be 
in the City of Boston, County of Suffolk. 

   SECTION 2.2. Other Offices. In addition to its principal office in the 
Commonwealth of Massachusetts, the Trust may have an office or offices in the 
City of New York, State of New York, and at such other places within and 
without the Commonwealth as the Trustees may from time to time designate or 
the business of the Trust may require. 

                                  ARTICLE III
                             SHAREHOLDERS' MEETINGS

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

   SECTION 3.2. Meetings. Meetings of Shareholders of the Trust shall be held 
whenever called by the Trustees or the President of the Trust and whenever 
election of a Trustee or Trustees by Shareholders is required by the 
provisions of Section 16(a) of the 1940 Act, for that purpose. Meetings of 
Shareholders shall also be called by the Secretary upon the written request 
of the holders of Shares entitled to vote not less than twenty-five percent 
(25%) of all the votes entitled to be cast at such meeting, except to the 
extent otherwise required by Section 16(c) of the 1940 Act, otherwise 
required by Section 16(c) of the 1940 Act and to the extent required by the 
corporate or, as made applicable to the Trust by the provisions of Section 
2.3 of the Declaration. Such request shall state the purpose or purposes of 
such meeting and the matters proposed to be acted on thereat. Except to the 
extent otherwise required by Section 16(c) of the 1940 Act, as made 
applicable to the Trust by the provisions of Section 2.3 of the Declaration, 
the Secretary shall inform such Shareholders of the reasonable estimated cost 
of preparing and mailing such notice of the meeting, and upon payment to the 
Trust of such costs, the Secretary shall give notice stating the purpose or 
purposes of the meeting to all entitled to vote at such meeting. No meeting 
need be called upon the request of the holders of Shares entitled to cast 
less than a majority of all votes entitled to be cast at such meeting, to 
consider any matter which is substantially the same as a matter voted upon at 
any meeting of Shareholders held during the preceding twelve months. 

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

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

<PAGE>

issued and outstanding and entitled to vote thereat, present in person or 
represented by proxy, shall be requisite and shall constitute a quorum for 
the transaction of business. In the absence of a quorum, the Shareholders 
present or represented by proxy and entitled to vote thereat shall have the 
power to adjourn the meeting from time to time. The Shareholders present in 
person or represented by proxy at any meeting and entitled to vote thereat 
also shall have the power to adjourn the meeting from time to time if the 
vote required to approve or reject any proposal described in the original 
notice of such meeting is not obtained (with proxies being voted for or 
against adjournment consistent with the votes for and against the proposal 
for which the required vote has not been obtained). The affirmative vote of 
the holders of a majority of the Shares then present in person or represented 
by proxy shall be required to adjourn any meeting. Any adjourned meeting may 
be reconvened without further notice or change in record date. At any 
reconvened meeting at which a quorum shall be present, any business may be 
transacted that might have been transacted at the meeting 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 Chairman and shall 
be called by the Chairman or the Secretary upon the written request of any 
two (2) Trustees. 

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

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

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

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

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

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

   SECTION 4.8. Indemnification of Trustees, Officers, Employees and 
Agents. (a) The Trust shall indemnify any person who was or is a party or is 
threatened to be made a party to any threatened, pending, or completed 
action, suit or proceeding, whether civil, criminal, administrative or 
investigative 

                                       3
<PAGE>

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

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

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

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

       (2) The determination shall be made: 

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

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

           (iii) By the Shareholders.

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

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

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

                                       4
<PAGE>

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

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

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

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

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

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

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

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

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

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

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

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

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

                                   ARTICLE V
                                   COMMITTEES

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

                                       5
<PAGE>

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

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

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

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

                                   ARTICLE VI

                          DIVIDENDS AND DISTRIBUTIONS

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

                                       7
<PAGE>

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

                                  ARTICLE VIII
                             CERTIFICATES OF SHARES

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

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

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

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

                                   ARTICLE IX

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

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

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

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

                                       8
<PAGE>

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

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

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

                                   ARTICLE X
                                WAIVER OF NOTICE

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

                                   ARTICLE XI
                                 MISCELLANEOUS

Trust may be kept outside the Commonwealth of Massachusetts at such place or 
places as the Trustees may from time to time determine, except as otherwise 
required by law. 

   SECTION 11.2. Record Date. The Trustees may fix in advance a date as the 
record date for the purpose of determining the Shareholders entitled to (i) 
receive notice of, or to vote at, any meeting of Shareholders, or (ii) 
receive payment of any dividend or the allotment of any rights, or in order 
to make a determination of Shareholders for any other proper purpose. The 
record date, in any case, shall not be more than one hundred eighty (180) 
days, and in the case of a meeting of Shareholders not less than ten (10) 
days, prior to the date on which such meeting is to be held or the date on 
which such other particular action requiring determination of Shareholders is 
to be taken, as the case may be. In the case of a meeting of Shareholders, 
the meeting date set forth in the notice to Shareholders accompanying the 
proxy statement shall be the date used for purposes of calculating the 180 
day or 10 day period, and any adjourned meeting may be reconvened without a 
change in record date. In lieu of fixing a record date, the Trustees may 
provide that the transfer books shall be closed for a stated period but not 
to exceed, in any case, twenty (20) days. If the transfer books are closed 
for the purpose of determining Shareholders entitled to notice of a vote at a 
meeting of Shareholders, such books shall be closed for at least ten (10) 
days immediately preceding the 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. 

                                       9

   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. 

                                  ARTICLE XII
                      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. 

                                  ARTICLE XIII
                                   AMENDMENTS

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

                                  ARTICLE XIV
                              DECLARATION OF TRUST

   The Declaration of Trust establishing TCW/DW North American Government 
Income Trust, dated February 19, 1992, a copy of which is on file in the

                             DISTRIBUTION AGREEMENT

   AGREEMENT made as of this 31st day of May, 1997 between TCW/DW North 
American Government Income Trust, an unincorporated business trust organized 
under the laws of the Commonwealth of Massachusetts (the "Fund" or "Trust"), 
and Dean Witter Distributors Inc., a Delaware corporation (the 
"Distributor"); 

                              W I T N E S S E T H:

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

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

   NOW, THEREFORE, the parties agree as follows: 

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

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

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

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

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

   (c) The Fund shall have the right to suspend the sale of the Shares at 
times when redemption is suspended pursuant to the conditions set forth in 
Section 4(d) hereof. The Fund shall also have the right 

<PAGE>

to suspend the sale of the Shares if trading on the New York Stock Exchange 
shall have been suspended, if a banking moratorium shall have been declared 
by federal or New York authorities, or if there shall have been some other 
extraordinary event which, in the judgment of the Fund, makes it 
impracticable to sell the Shares. 

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

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

   SECTION 4. Repurchase or Redemption of Shares. (a) Any of the outstanding 
Shares may be tendered for redemption at any time, and the Fund agrees to 
redeem the Shares so tendered in accordance with the applicable provisions 
set forth in the Prospectus. The price to be paid to redeem the Shares shall 
be equal to the net asset value determined as set forth in the Prospectus. 
All payments by the Fund hereunder shall be made in the manner set forth 
below. 

   Upon any redemption of Shares the Fund shall pay the total amount of the 
redemption price in accordance with applicable provisions of the Prospectus 
in New York Clearing House funds, or in portfolio securities in event of 
redemptions in kind, on or before the seventh day subsequent to its having 
received the notice of redemption in proper form. 

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

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

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

   (e) With respect to Shares tendered for redemption or repurchase by any 
Selected Dealer on behalf of its customers, the Distributor is authorized to 
instruct the transfer agent of the Trust to accept orders for redemption or 
repurchase directly from the Selected Dealer on behalf of the Distributor and 
to instruct the Trust to transmit payments for such redemptions and 
repurchases directly to the Selected 

                                       2
<PAGE>

Dealer on behalf of the Distributor for the account of the shareholder. The 
Distributor shall obtain from the Selected Dealer, and shall maintain, a 
record of such orders. The Distributor is further authorized to obtain from 
the Trust; and shall maintain, a record of payments made directly to the 
Selected Dealer on behalf of the Distributor. 

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

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

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

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

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

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

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

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

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

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

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

                                       3
<PAGE>

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

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

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

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

                                       4
<PAGE>

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

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

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

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

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

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

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

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

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

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

   SECTION 13. Personal Liability. The Declaration of the Trust establishing 
TCW/DW North American Government Income Trust, dated February 19, 1992, a 
copy of which, together with all amendments thereto (the "Declaration"), is 
on file in the office of the Secretary of the Commonwealth of Massachusetts, 
provides that the name TCW/DW North American Government Income Trust refers 
to the Trustees under the Declaration collectively as Trustees, but not as 
individuals or personally; and no Trustee, shareholder, officer, employee or 
agent of TCW/DW North American Government Income Trust shall be held to any 
personal liability, nor shall resort be had to their private property for the 
satisfaction of any obligation or claim or otherwise, in connection with the 
affairs of said TCW/DW North American Government Income Trust, but the Trust 
Estate only shall be liable. 

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

to accept such appointment; 

   NOW THEREFORE, in consideration of the mutual covenants herein contained, 
the parties hereto agree as follows: 

Article 1 Terms of Appointment; Duties of DWTFSB 

   1.1 Subject to the terms and conditions set forth in this Agreement, the 
Fund hereby employs and appoints DWTFSB to act as, and DWTFSB agrees to act 
as, the transfer agent for each series and class of shares of the Fund, 
whether now or hereafter authorized or issued ("Shares"), dividend disbursing 
agent and shareholder servicing agent in connection with any accumulation, 
open-account or similar plans provided to the holders of such Shares 
("Shareholders") and set out in the currently effective prospectus and 
statement of additional information ("prospectus") of the Fund, including 
without limitation any periodic investment plan or periodic withdrawal 
program. 

   1.2 DWTFSB agrees that it will perform the following services: 

       (a) In accordance with procedures established from time to time by
   agreement between the Fund and DWTFSB, DWTFSB shall:

           (i) Receive for acceptance, orders for the purchase of Shares, and
       promptly deliver payment and appropriate documentation therefor to the
       custodian of the assets of the Fund (the "Custodian");

           (ii) Pursuant to purchase orders, issue the appropriate number of
       Shares and issue certificates therefor or hold such Shares in book form
       in the appropriate Shareholder account;

           (iii) Receive for acceptance redemption requests and redemption
       directions and deliver the appropriate documentation therefor to the
       Custodian;

           (iv) At the appropriate time as and when it receives monies paid to
       it by the Custodian with respect to any redemption, pay over or cause to
       be paid over in the appropriate manner such monies as instructed by the

           (v) Effect transfers of Shares by the registered owners thereof upon
       receipt of appropriate instructions;

           (vi) Prepare and transmit payments for dividends and distributions
       declared by the Fund;

           (vii) Calculate any sales charges payable by a Shareholder on

           (viii) Maintain records of account for and advise the Fund and its 
       Shareholders as to the foregoing; and 

           (ix) Record the issuance of Shares of the Fund and maintain pursuant

       Act") a record of the total number of Shares of the Fund which are
       authorized, based upon data provided to it by the Fund, and issued and
       outstanding. DWTFSB shall also provide to the Fund on a regular basis
       the total number of Shares that are authorized, issued and outstanding
       and shall notify the Fund in case any proposed issue of Shares by the
       Fund would result in an overissue. In case any issue of Shares

<PAGE>

       would result in an overissue, DWTFSB shall refuse to issue such Shares 
       and shall not countersign and issue any certificates requested for 
       such Shares. When recording the issuance of Shares, DWTFSB shall have 
       no obligation to take cognizance of any Blue Sky laws relating to the 
       issue of sale of such Shares, which functions shall be the sole 
       responsibility of the Fund.

   above paragraph (a), DWTFSB shall:

           (i) perform all of the customary services of a transfer agent,

       in connection with dividend reinvestment, accumulation, open-account or
       similar plans (including without limitation any periodic investment plan
       or periodic withdrawal program), including but not limited to,
       maintaining all Shareholder accounts, preparing Shareholder meeting
       lists, mailing proxies, receiving and tabulating proxies, mailing
       shareholder reports and prospectuses to current Shareholders,
       withholding taxes on U.S. resident and non-resident alien accounts,
       preparing and filing appropriate forms required with respect to
       dividends and distributions by federal tax authorities for all
       Shareholders, preparing and mailing confirmation forms and statements of
       account to Shareholders for all purchases and redemptions of Shares and
       other confirmable transactions in Shareholder accounts, preparing and
       mailing activity statements for Shareholders and providing Shareholder
       account information;

           (ii) open any and all bank accounts which may be necessary or
       appropriate in order to provide the foregoing services; and

           (iii) provide a system that will enable the Fund to monitor the

       (c) In addition, the Fund shall: 

           (i) identify to DWTFSB in writing those transactions and assets to
       be treated as exempt from Blue Sky reporting for each State; and

           (ii) verify the inclusion on the system prior to activation of each

       purchases and sales for shareholders in each State. The responsibility
       of DWTFSB for the Fund's status under the securities laws of any State
       or other jurisdiction is limited to the inclusion on the system of each
       State as to which the Fund has informed DWTFSB that shares may be sold
       in compliance with state securities laws and the reporting of purchases
       and sales in each such State to the Fund as provided above and as agreed
       from time to time by the Fund and DWTFSB.

       (d) DWTFSB shall provide such additional services and functions not
   specifically described herein as may be mutually agreed between DWTFSB and
   the Fund. Procedures applicable to such services may be established from
   time to time by agreement between the Fund and DWTFSB.

Article 2 Fees and Expenses 

   2.1 For performance by DWTFSB pursuant to this Agreement, each Fund agrees 
to pay DWTFSB an annual maintenance fee for each Shareholder account and 
certain transactional fees, if applicable, as set out in the respective fee 
schedule attached hereto as Schedule A. Such fees and out-of-pocket expenses 
and advances identified under Section 2.2 below may be changed from time to 
time subject to mutual written agreement between the Fund and DWTFSB. 

   2.2 In addition to the fees paid under Section 2.1 above, the Fund agrees 
to reimburse DWTFSB for out of pocket expenses in connection with the 
services rendered by DWTFSB hereunder. In addition, any other expenses 
incurred by DWTFSB at the request or with the consent of the Fund will be 
reimbursed by the Fund. 

   2.3 The Fund agrees to pay all fees and reimbursable expenses within a 
reasonable period of time following the mailing of the respective billing 
notice. Postage for mailing of dividends, proxies, Fund reports and other 
mailings to all Shareholder accounts shall be advanced to DWTFSB by the Fund 
upon request prior to the mailing date of such materials.

   5.2 DWTFSB shall indemnify and hold the Fund harmless from or against any 
and all losses, damages, costs, charges, counsel fees, payments, expenses and 
liability arising out of or attributable to any action or failure or omission

readable input, telex, CRT data entry or other similar means authorized by 
the Fund, and shall not be held to have notice of any change of authority of

the other for any damages resulting from such failure to perform or otherwise 
from such causes.

consequential damages under any provision of this Agreement or for any act or 
failure to act hereunder.

5 shall apply, upon the assertion of a claim for which either party may be 
required to indemnify the other, the party seeking indemnification shall 
promptly notify the other party of such assertion, and shall keep the other 
party advised with respect to all developments concerning such claim. The 
party who may be required to indemnify shall have the option to participate 
with the party seeking indemnification in the defense of such claim. The 
party seeking indemnification shall in no case confess any claim or make any 
compromise in any case in which the other party may be required to indemnify 
it except with the other party's prior written consent.

        AMENDED AND RESTATED PLAN OF DISTRIBUTION PURSUANT TO RULE 12B-1
                                       OF
                 TCW/DW NORTH AMERICAN GOVERNMENT INCOME TRUST

   WHEREAS, TCW/DW North American Government Income Trust (the "Fund") is 
engaged in business as an open-end management investment company and is 
registered as such under the Investment Company Act of 1940, as amended (the 
"Act"); and 

   WHEREAS, on April 28, 1993, the Fund most recently amended and restated a 
Plan and Agreement of Distribution pursuant to Rule 12b-1 under the Act which 
had initially been adopted on June 2, 1992, and the Trustees then determined 
that there was a reasonable likelihood that the Plan of Distribution, as then 
amended and restated, would benefit the Fund and its shareholders; and 

   WHEREAS, the Trustees believe that continuation of said Plan of 
Distribution, as amended and restated herein, is reasonably likely to 
continue to benefit the Fund and its shareholders; and 

   WHEREAS, the Agreement incorporated in said initial Plan and Agreement of 
Distribution was entered into by the Fund with Dean Witter Reynolds Inc. 
("DWR"); and 

   WHEREAS, on January 4, 1993, the Fund and DWR substituted Dean Witter 
Distributors Inc. (the "Distributor") in the place of DWR as distributor of 
the Fund's shares; and 

   WHEREAS, the Fund, DWR and the Distributor intend that DWR will continue 
to promote the sale of Fund shares and provide personal services to Fund 
shareholders with respect to their holdings of Fund shares; and 

   WHEREAS, the Fund and the Distributor have entered into a separate 
Distribution Agreement dated as of May 31, 1997, pursuant to which the Fund 
has employed the Distributor in such capacity during the continuous offering 
of shares of the Fund. 

   NOW, THEREFORE, the Fund hereby amends and restates the Plan of 
Distribution previously adopted and amended and restated, and the Distributor 
hereby agrees to the terms of said Plan of Distribution (the "Plan"), as 
amended and restated herein, in accordance with Rule 12b-1 under the Act on 
the following terms and conditions: 

   1. The Fund is hereby authorized to utilize its assets to finance certain 
activities in connection with the distribution of its shares. 

   2. Subject to the supervision of the Trustees and the terms of the 
Distribution Agreement, the Distributor is authorized to promote the 
distribution of the Fund's shares and to provide related services through 
DWR, its affiliates or other broker-dealers it may select, and its own 
Registered Representatives. The Distributor, DWR, its affiliates and said 
broker-dealers shall be reimbursed, directly or through the Distributor, as 
it may direct, as provided in paragraph 4 hereof for their services and 
expenses, which may include one or more of the following: (1) compensation 
to, and expenses of, account executives and other employees, including 
overhead and telephone expenses; (2) sales incentives and bonuses to sales 
representatives of the Distributor, DWR, its affiliates and other 
broker-dealers, and to marketing personnel in connection with promoting sales 
of shares of the Fund; (3) expenses incurred in connection with promoting 
sales of shares of the Fund; (4) preparing and distributing sales literature; 
and (5) providing advertising and promotional activities, including direct 
mail solicitation and television, radio, newspaper, magazine and other media 
advertisements. 

   3. The Distributor hereby undertakes to directly bear all costs of 
rendering the services to be performed by it under this Plan and under the 
Distribution Agreement, except for those specific expenses that the Trustees 
determine to reimburse as hereinafter set forth. 

   4. The Fund is hereby authorized to reimburse the Distributor, DWR, its 
affiliates and other broker-dealers for incremental distribution expenses 
incurred by them specifically on behalf of the Fund. Reimbursement will be 
made through payments at the end of each month. The amount of each monthly 
payment may in no event exceed an amount equal to a payment at the annual 
rate of 0.75 of 1% of the Fund's average net assets during the month. In the 
case of all expenses other than expenses representing 

<PAGE>

a residual to account executives, such amounts shall be determined at the 
beginning of each calendar quarter by the Trustees, including a majority of 
the Trustees who are not "interested persons" of the Fund, as defined in the 
Act. Expenses representing a residual to account executives may be reimbursed 
without prior determination. In the event that the Distributor proposes that 
monies shall be reimbursed for other than such expenses, then in making the 
quarterly determinations of the amounts that may be expended by the Fund, the 
Distributor shall provide, and the Trustees shall review, a quarterly budget 
of projected incremental distribution expenses to be incurred by the 
Distributor, DWR, its affiliates or other broker-dealers on behalf of the 
Fund, together with a report explaining the purposes and anticipated benefits 
of incurring such expenses. The Trustees shall determine the particular 
expenses, and the portion thereof, that may be borne by the Fund, and in 
making such determination shall consider the scope of the Distributor's 
commitment to promoting the distribution of the shares of the Fund directly 
or through DWR, its affiliates or other broker-dealers. All payments made 
hereunder pursuant to the Plan shall be in accordance with the Rules of the 
Association of the National Association of Securities Dealers, Inc. 

   5. The Distributor may direct that all or any part of the amounts 
receivable by it under this Plan be paid directly to DWR, its affiliates or 
other broker-dealers. 

   6. If, as of the end of any calendar year, the actual expenses incurred by 
the Distributor, DWR, its affiliates and other broker-dealers on behalf of 
the Fund (including accrued expenses and amounts reserved for incentive 
compensation and bonuses) are less than the amount of payments made by the 
Fund pursuant to this Plan, the Distributor shall promptly make appropriate 
reimbursement to the Fund. If, however, as of the end of any calendar year, 
the actual expenses of the Distributor, DWR, its affiliates and other 
broker-dealers are greater than the amount of payments made by the Fund 
pursuant to this Plan, the Fund will not reimburse the Distributor, DWR, its 
affiliates or other broker-dealers for such expenses through payments accrued 
pursuant to this Plan in the subsequent calendar year. 

   7. The Distributor shall provide to the Trustees of the Fund and the 
Trustees shall review, promptly after the end of each calendar quarter, a 
written report regarding the incremental distribution expenses incurred by 
the Distributor, DWR, its affiliates or other broker-dealers on behalf of the 
Fund during such calendar quarter, which report shall include: (1) an 
itemization of the types of expenses and the purposes therefor; (2) the 
amounts of such expenses; and (3) a description of the benefits derived by 
the Fund. 

   8. This Plan, as amended and restated, shall become effective upon 
approval by a vote of the Trustees of the Fund, and of the Trustees who are 
not "interested persons" of the Fund, as defined in the Act, and who have no 
direct or indirect financial interest in the operation of this Plan, cast in 
person at a meeting called for the purpose of voting on this Plan. 

   9. This Plan shall continue in effect until April 30, 1998 and from year 
to year thereafter, provided such continuance is specifically approved at 
least annually in the manner provided for approval of this Plan in paragraph 
8 hereof. This Plan may not be amended to increase materially the amount to 
be spent for the services described herein unless such amendment is approved 
by a vote of at least a majority of the outstanding voting securities of the 
Fund, as defined in the Act, and no material amendment to this Plan shall be 
made unless approved in the manner provided for approval in paragraph 8 
hereof. 

   10. This Plan may be terminated at any time, without the payment of any 
penalty, by vote of a majority of the Trustees who are not "interested 
persons" of the Fund, as defined in the Act, and who have no direct or 
indirect financial interest in the operation of this Plan or by a vote of a 
majority of the outstanding voting securities of the Fund, as defined in the 
Act, on no more than thirty days' written notice to any other party to this 
Plan. 

   11. While this Plan is in effect, the selection and nomination of Trustees 
who are not interested persons of the Fund shall be committed to the 
discretion of the Trustees who are not interested persons. 

   12. The Fund shall preserve copies of this Plan and all reports made 
pursuant to paragraph 7 hereof, for a period of not less than six years from 
the date of this Plan, as amended and restated herein, or any such report, as 
the case may be, the first two years in an easily accessible place. 

   13. This Plan shall be construed in accordance with the laws of the State 
of New York and the applicable provisions of the Act. To the extent the 
applicable law of the State of New York, or any of the provisions herein, 
conflicts with the applicable provisions of the Act, the latter shall 
control.
