                           TAX FREE HIGH INCOME FUND
- ------------------------------------------------------------------------------
 
    Van Kampen American Capital Tax Free High Income Fund (the "Fund") is a
separate diversified mutual fund organized as a series of Van Kampen American
Capital Tax Free Trust. The Fund's investment objective is to provide investors
with a high level of current income exempt from federal income taxes primarily
through investment in a diversified portfolio of medium and lower grade
municipal securities. The Fund may invest in medium and lower grade municipal
securities rated between BBB and B- (inclusive) by Standard & Poor's Ratings
Group, Baa and B3 (inclusive) by Moody's Investors Service, Inc., comparably
rated short-term municipal obligations and municipal securities determined by
the Fund's investment adviser to be of comparable quality. Municipal securities
in which the Fund may invest include conventional fixed-rate municipal
securities, variable rate municipal securities and other types of municipal
securities described herein. See "Municipal Securities." There is no assurance
that the Fund will achieve its investment objective.
 
    Investment in medium and lower grade municipal securities involves special
risks as compared with investment in higher grade municipal securities,
including potentially greater sensitivity to a general economic downturn,
greater market price volatility and less liquid secondary market trading. See
"Municipal Securities -- Special Considerations and Risk Factors Regarding
Medium and Lower Grade Municipal Securities." Investment in the Fund may not be
appropriate for all investors.
 
    The Fund's investment adviser is Van Kampen American Capital Investment
Advisory Corp. This Prospectus sets forth certain information about the Fund

                               PROSPECTUS SUMMARY
- ------------------------------------------------------------------------------
 
THE FUND.  Van Kampen American Capital Tax Free High Income Fund (the "Fund") is
a separate diversified series of Van Kampen American Capital Tax Free Trust (the
"Trust"), an open-end management investment company organized as a Delaware
business trust. See "The Fund."
 
MINIMUM PURCHASE.  $500 minimum initial investment for each class of shares and
$25 minimum subsequent investment for each class of shares (or less as described
under "Purchase of Shares").
 
INVESTMENT OBJECTIVE.  The Fund's investment objective is to provide investors
with a high level of current income exempt from federal income taxes primarily
through investment in a diversified portfolio of medium and lower grade
municipal securities.
 
INVESTMENT POLICIES.  Municipal securities in which the Fund may invest include
fixed and variable rate securities, municipal notes, municipal leases, tax
exempt commercial paper, custodial receipts, participation certificates and
derivative municipal securities the terms of which include elements of, or are
similar in effect to, certain Strategic Transactions (as defined herein) in
which the Fund may engage. The Fund may invest up to 15% of its total assets in
derivative variable rate securities such as inverse floaters, whose rates vary
inversely with changes in market rates of interest or range or capped floaters,
whose rates are subject to periodic or lifetime caps. The Fund may invest in
medium and lower grade municipal securities rated, at the time of investment,
between BBB and B- (inclusive) by Standard & Poor's Ratings Group ("S&P"), Baa
and B3 (inclusive) by Moody's Investors Service, Inc. ("Moody's"), comparably
rated short-term municipal obligations and municipal securities determined by
Van Kampen American Capital Investment Advisory Corp. (the "Adviser"), the
Fund's investment adviser, to be of comparable quality. There is no assurance
that the Fund will achieve its investment objective.
 
  Medium grade municipal securities are those rated BBB by S&P or Baa by
Moody's, comparably rated short-term municipal obligations and municipal
securities determined by the Adviser to be of comparable quality. Municipal
securities rated BBB by S&P generally are regarded by S&P as having an adequate
capacity to pay interest and repay principal; adverse economic conditions or
changing circumstances are, however, more likely in S&P's view to lead to a
weakened capacity to pay interest and repay principal as compared with higher
rated municipal securities. Municipal securities rated Baa by Moody's generally
are considered by Moody's as medium grade obligations, i.e., they are neither
highly protected nor poorly secured. In Moody's view, 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. In
 
                                        3
<PAGE>   20
 
Moody's view, such securities lack outstanding investment characteristics and
have speculative characteristics as well.
 
  The Fund may invest in lower grade municipal securities rated, at the time of
investment, either not lower than B- by S&P or not lower than B3 by Moody's, in
comparably rated short-term municipal obligations and in municipal securities
determined by the Adviser to be of comparable quality. Municipal securities
rated B by S&P generally are regarded by S&P, on balance, as predominantly
speculative with respect to capacity to pay interest or repay principal in
accordance with the terms of the obligation. While such securities will likely
have some quality and protective characteristics, in S&P's view these are
outweighed by large uncertainties or major risk exposure to adverse conditions.
Securities rated B by Moody's are viewed by Moody's as generally lacking
characteristics of the desirable investment. In Moody's view, assurance of
interest and principal payments or of maintenance of other terms of the contract
over any long period of time may be small.
 
  The Fund will not make initial investments in municipal securities rated, at
the time of investment, below B- by S&P and below B3 by Moody's, in comparably
rated short-term municipal obligations or in municipal securities determined by
the Adviser to be of comparable quality. The Fund may retain municipal
securities which are downgraded after investment. There is no minimum rating
with respect to municipal securities which may be retained in the Fund's
portfolio, and the Fund may thus hold securities that are in default, or with
respect to which payment of interest and/or repayment of principal is in
arrears. A complete description of the various S&P and Moody's rating categories
is included as Appendix A to this Prospectus.
 
  Investment in medium and lower grade municipal securities involves special
risks as compared with investment in higher grade municipal securities,
including potentially greater sensitivity to a general economic downturn,
greater market price volatility and less liquid secondary market trading. The
Fund may not be an appropriate investment for all investors. The net asset value
per share of the Fund can be expected to increase or decrease depending on real
or perceived changes in the credit risks associated with its portfolio
investments, changes in interest rates and other factors affecting the municipal
credit markets. See "Investment Objective and Policies," "Municipal Securities"
and "Appendix A."
 
INVESTMENT PRACTICES.  In certain circumstances the Fund may enter into when-
issued or delayed delivery transactions and various strategic transactions,
which practices entail certain risks. See "Investment Practices."
 
INVESTMENT RESULTS.  The investment results of the Fund are shown in the table
of "Financial Highlights."
 
ALTERNATIVE SALES ARRANGEMENTS.  The Alternative Sales Arrangements permit an
investor to choose the method of purchasing shares that is more beneficial to
the investor, taking into account the amount of the purchase, the length of time
the investor expects to hold the shares and other circumstances. Investors
should
 
                                        4
<PAGE>   21
 
consider such factors together with the amount of sales charges and accumulated
distribution and services fees with respect to each class of shares that may be
incurred over the anticipated duration of their investment in the Fund. To
assist investors in making this determination, the table under the caption
"Annual Fund Operating Expenses and Example" sets forth examples of the charges
applicable to each class of shares.
 
  The Fund currently offers three classes of its shares which may be purchased
at a price equal to their net asset value per share plus sales charges which, at
the election of the investor, may be imposed either (i) at the time of purchase
("Class A Shares") or (ii) on a contingent deferred basis (Class A Share
accounts over $1 million, "Class B Shares" and "Class C Shares"). Class A Share
accounts over $1 million or otherwise subject to a contingent deferred sales
charge ("CDSC"), Class B Shares and Class C Shares sometimes are referred to
herein collectively as "CDSC Shares."
 
  Class A Shares. Class A Shares are subject to an initial sales charge equal to
4.75% of the public offering price (4.99% of the net amount invested), reduced
on investments of $100,000 or more. Class A Shares are subject to ongoing
distribution and services fees at an aggregate annual rate of up to 0.25% of the
Fund's average daily net assets attributable to the Class A Shares. Certain
purchases of Class A Shares qualify for reduced or no initial sales charges and
may be subject to a CDSC.
 
   
  Class B Shares. Class B Shares do not incur a sales charge when they are
purchased, but are subject to a sales charge if redeemed within six years of
purchase. Class B Shares are subject to a CDSC equal to 4.00% of the lesser of
the then current net asset value or the original purchase price on Class B
Shares redeemed during the first year after purchase, which charge is reduced
each year thereafter. Class B Shares are subject to ongoing distribution and
service fees at an aggregate annual rate of up to 1.00% of the Fund's average
daily net assets attributable to the Class B Shares. Class B Shares
automatically convert to Class A Shares eight years after the end of the
calendar month in which the investor's order to purchase was accepted, in the
circumstances and subject to the qualifications described in this Prospectus.
    
 
   
  Class C Shares. Class C Shares do not incur a sales charge when they are
purchased, but are subject to a sales charge if redeemed within the first year
after purchase. Class C Shares are subject to a CDSC equal to 1.00% of the
lesser of the then current net asset value or the original purchase price on
Class C Shares redeemed within the first year after purchase. Class C Shares are
subject to ongoing distribution and service fees at an aggregate annual rate of
up to 1.00% of the Fund's aggregate average daily net assets attributable to the
Class C Shares.
    
 
                                        5
<PAGE>   22
 
   
REDEMPTION.  Class A Shares may be redeemed at net asset value, without charge,
subject to conditions set forth herein. CDSC Shares may be redeemed at net asset
value less a deferred sales charge which will vary among each class of CDSC
Shares and with the length of time a redeeming shareholder has owned such
shares. CDSC Shares redeemed after the expiration of the CDSC period applicable
to the respective class of CDSC Shares will not be subject to a deferred sales
charge. See "Redemption of Shares."
    
 
   
INVESTMENT ADVISER.  Van Kampen American Capital Investment Advisory Corp. (the
"Adviser") is the Fund's investment adviser.
    
 
   
DISTRIBUTOR.  Van Kampen American Capital Distributors, Inc. (the "Distributor")
distributes the Fund's shares.
    
 
DISTRIBUTIONS FROM THE FUND.  Distributions from net investment income are
declared daily and paid monthly; net realized capital gains, if any, are
distributed annually. Distributions with respect to each class of shares will be
calculated in the same manner on the same day and will be in the same amount
except that the different distribution and service fees and administrative
expenses relating to each class of shares will be borne exclusively by the
respective class of shares. See "Distributions from the Fund."
 
   
  The foregoing is qualified in its entirety by reference to the more detailed
    
              information appearing elsewhere in this Prospectus.

THE FUND
- ------------------------------------------------------------------------------
 
  Van Kampen American Capital Tax Free High Income Fund ("Fund") is a separate
diversified series of Van Kampen American Capital Tax Free Trust (the "Trust"),
which is an open-end management investment company, commonly known as a "mutual
fund," organized as a Delaware business trust. Mutual funds sell their shares to
investors and invest the proceeds in a portfolio of securities. A mutual fund
allows investors to pool their money with that of other investors in order to
obtain professional investment management. Mutual funds generally make it
possible for investors to obtain greater diversification of their investments
and to simplify their recordkeeping.
 
  Van Kampen American Capital Investment Advisory Corp. (the "Adviser") provides
investment advisory and administrative services to the Fund. The Adviser and its
affiliates also manage other mutual funds distributed by Van Kampen American
Capital Distributors, Inc. (the "Distributor"). To obtain prospectuses and other
information on any of these other funds, please call the telephone number on the
cover page of the Prospectus.
 
- ------------------------------------------------------------------------------
INVESTMENT OBJECTIVE AND POLICIES
- ------------------------------------------------------------------------------
 
  The investment objective of the Fund is to provide investors with a high level
of current income exempt from federal income taxes primarily through investment
in a diversified portfolio of medium and lower grade municipal securities. The
Fund may invest in medium and lower grade municipal securities rated, at the
time of investment, between BBB and B- (inclusive) by Standard & Poor's Ratings
Group ("S&P"), Baa and B3 (inclusive) by Moody's Investors Service, Inc.
("Moody's"), comparably rated short-term municipal obligations and municipal
securities determined by the Adviser to be of comparable quality. There is no
assurance that the Fund will achieve its investment objective. An investment in
the Fund may not be appropriate for all investors. The Fund is not intended to
be a complete investment program, and investors should consider their long-term
investment goals and financial needs when making an investment decision with
respect to the Fund. An investment in the Fund is intended to be a long-term
investment and should not be used as a trading vehicle.
 
  The Fund generally invests its assets in municipal securities, the interest on
which, in the opinion of bond counsel or other counsel to the issuer of such
securities, is exempt from federal income tax. See "Municipal Securities." In
normal circumstances, up to 100%, but not less than 80%, of the Fund's net
assets will be invested in such municipal securities. The foregoing is a
fundamental policy and cannot be changed without shareholder approval. Any
"private activity" obligations in which the Fund may invest will not be treated
as municipal securities for purposes of the 80% test. The Fund also may invest
up to 10% of its assets in tax-exempt money market funds that invest in
securities rated comparably to those
 
                                       12
<PAGE>   29
 
in which the Fund may invest. Such instruments will be treated as municipal
securities for purposes of the 80% test.
 
  Medium grade municipal securities are those rated BBB by S&P or Baa by
Moody's, comparably rated short-term municipal obligations and municipal
securities determined by the Adviser to be of comparable quality. Municipal
securities rated BBB by S&P generally are regarded by S&P as having an adequate
capacity to pay interest and repay principal; adverse economic conditions or
changing circumstances are, however, more likely in S&P's view to lead to a
weakened capacity to pay interest and repay principal as compared with higher
rated municipal securities. Municipal securities rated Baa by Moody's generally
are considered by Moody's as medium grade obligations, i.e., they are neither
highly protected nor poorly secured. In Moody's view, 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. In Moody's view, such securities lack outstanding investment
characteristics and have speculative characteristics as well.
 
  The Fund may invest in lower grade municipal securities rated, at the time of
investment, either not lower than B- by S&P or not lower than B3 by Moody's, in
comparably rated short-term municipal obligations and in municipal securities
determined by the Adviser to be of comparable quality. Municipal securities
rated B by S&P generally are regarded by S&P, on balance, as predominantly
speculative with respect to capacity to pay interest or repay principal in
accordance with the terms of the obligation. While such securities will likely
have some quality and protective characteristics, in S&P's view these are
outweighed by large uncertainties or major risk exposure to adverse conditions.
Securities rated B by Moody's are viewed by Moody's as generally lacking
characteristics of the desirable investment. In Moody's view, assurance of
interest and principal payments or of maintenance of other terms of the contract
over any long period of time may be small.
 
  The Fund will not make initial investments in municipal securities rated, at
the time of investment, below B- by S&P and below B3 by Moody's, in comparably
rated short-term municipal obligations or in municipal securities determined by
the Adviser to be of comparable quality. The Fund may retain municipal
securities which are downgraded after investment. There is no minimum rating
with respect to municipal securities which may be retained in the Fund's
portfolio, and the Fund may thus hold securities that are in default or with
respect to which payment of interest and/or repayment of principal is in
arrears. A complete description of the various S&P and Moody's rating categories
is included as Appendix A to this Prospectus.
 
  Investment in medium and lower grade securities involves special risks as
compared with investment in higher grade securities, including potentially
greater sensitivity to a general economic downturn, greater market price
volatility and less liquid secondary market trading. See "Municipal
Securities--Special Considerations
 
                                       13
<PAGE>   30
 
and Risk Factors Regarding Medium and Lower Grade Municipal Securities." There
can be no assurance that the Fund will achieve its investment objective, and the
Fund may not be an appropriate investment for all investors. Furthermore,
interest on certain "private activity" obligations in which the Fund may invest
is treated as a preference item for the purpose of calculating the alternative
minimum tax and, accordingly, a portion of the income produced by the Fund may
be taxable under the alternative minimum tax. The Fund may not be a suitable
investment for investors who are already subject to the federal alternative
minimum tax or who would become subject to the federal alternative minimum tax
as a result of an investment in the Fund. See "Tax Status."
 
  At times the Adviser may judge that conditions in the markets for medium and
lower grade municipal securities make pursuing the Fund's basic investment
strategy of investing primarily in such municipal securities inconsistent with
the best interests of shareholders. At such times, the Fund may invest all or a
portion of its assets in higher grade municipal securities and in municipal
securities determined by the Adviser to be of comparable quality. Although such
higher grade municipal securities generally entail less credit risk, such higher
grade municipal securities may have a lower yield than medium and lower grade
municipal securities and investment in such higher grade municipal securities
may result in a lower yield to Fund shareholders. The Adviser may also judge
that conditions in the markets for long- and intermediate-term municipal
securities in general make pursuing the Fund's basic investment strategy
inconsistent with the best interests of the Fund's shareholders. At such times,
the Fund may pursue strategies primarily designed to reduce fluctuations in the
value of the Fund's assets, including investing the Fund's assets in
high-quality, short-term municipal securities and in high-quality, short-term
taxable securities. See "Tax Status."
 
   
  The table below sets forth the percentages of the Fund's assets invested

comparable quality. The percentages are based on the dollar-weighted average of
credit ratings

  Securities rated D are in default, and payment of interest and/or repayment of
principal is in arrears. Securities that are in default or with respect to which
payment of interest and/or repayment of principal is in arrears present special
risk considerations. The Fund may incur additional expenses to the extent that
it is required to seek recovery of interest or principal, and the Fund may be
unable to obtain full recovery thereof. See "Municipal Securities--Special
Considerations and Risk Factors Regarding Medium and Lower Grade Municipal
Securities."
 
  The portfolio composition shown in the table above reflects the allocation of
assets by the Fund during periods of relative instability in the market for
medium and lower grade securities. The percentage of the Fund's assets invested
in securities of various grades may from time to time vary substantially from
those set forth above.

MUNICIPAL SECURITIES
- ------------------------------------------------------------------------------
 
  GENERAL. Municipal securities in which the Fund may invest are debt
obligations issued by or on behalf of the governments of states, territories or
possessions of the United States, the District of Columbia and their political
subdivisions, agencies and instrumentalities, certain interstate agencies and
certain territories of the United States, the interest on which, in the opinion
of bond counsel or other counsel to the issuer of such securities, is exempt
from federal income tax.
 
                                       15
<PAGE>   32
 
  The two principal classifications of municipal securities are "general
obligation" and "revenue" securities. "General obligation" securities are
secured by the issuer's pledge of its faith, credit and taxing power for the
payment of principal and interest. "Revenue" securities are usually payable only
from the revenues derived from a particular facility or class of facilities or,
in some cases, from the proceeds of a special excise tax or other specific
revenue source. Industrial development bonds are usually revenue securities, the
credit quality of which is normally directly related to the credit standing of
the industrial user involved.
 
  Within these principal classifications of municipal securities, there are a
variety of categories of municipal securities, including fixed and variable rate
securities, municipal bonds, municipal notes, municipal leases, custodial
receipts, participation certificates and derivative municipal securities the
terms of which include elements of, or are similar in effect to, certain
Strategic Transactions (as defined below) in which the Fund may engage. Variable
rate securities bear rates of interest that are adjusted periodically according
to formulae intended to reflect market rates of interest and include securities
whose rates vary inversely with changes in market rates of interest. The Fund
will not invest more than 15% of its total assets in derivative municipal
securities such as inverse floaters, whose rates vary inversely with changes in
market rates of interest, or range floaters or capped floaters whose rates are
subject to periodic or lifetime caps. Such securities may also pay a rate of
interest determined by applying a multiple to the variable rate. The extent of
increases and decreases in the value of securities whose rates vary inversely
with market rates of interest generally will be larger than comparable changes
in the value of an equal principal amount of a fixed rate municipal security
having similar credit quality, redemption provisions and maturity. Municipal
notes include tax, revenue and bond anticipation notes of short maturity,
generally less than three years, which are issued to obtain temporary funds for
various public purposes. Municipal leases are obligations issued by state and
local governments or authorities to finance the acquisition of equipment and
facilities. Certain municipal lease obligations may include "non-appropriation"
clauses which provide that the municipality has no obligation to make lease or
installment purchase payments in future years unless money is appropriated for
such purpose on a yearly basis. Custodial receipts are underwritten by
securities dealers or banks and evidence ownership of future interest payments,
principal payments or both on certain municipal securities. Participation
certificates are obligations issued by state and local governments or
authorities to finance the acquisition of equipment and facilities. They may
represent participations in a lease, an installment purchase contract, or a
conditional sales contract. Some municipal securities may not be backed by the
faith, credit and taxing power of the issuer. Certain of the municipal
securities in which the Fund may invest represent relatively recent innovations
in the municipal securities markets. While markets for such recent innovations
progress through stages of development, such markets may be less developed than
more fully developed markets for municipal securities. A more detailed
description of the types of
 
                                       16
<PAGE>   33
 
municipal securities in which the Fund may invest is included in the Statement
of Additional Information.
 
  The net asset value of each of the Funds will change with changes in the value
of their respective portfolio securities. Because the Funds will invest
primarily in fixed income municipal securities, the net asset value of each of
the Funds can be expected to change as general levels of interest rates
fluctuate. When interest rates decline, the value of a portfolio invested in
fixed income securities generally can be expected to rise. Conversely, when
interest rates rise, the value of a portfolio invested in fixed income
securities generally can be expected to decline. Volatility may be greater
during periods of general economic uncertainty.
 
  From time to time, proposals have been introduced before Congress that would
have the effect of reducing or eliminating the federal tax exemption on
municipal securities. If such a proposal were enacted, the ability of the Fund
to pay tax-exempt interest dividends might be adversely affected.
 
  SPECIAL CONSIDERATIONS AND RISK FACTORS REGARDING MEDIUM AND LOWER GRADE
MUNICIPAL SECURITIES. The Fund invests in medium and lower grade municipal
securities. Municipal securities which are in the medium and lower grade
categories generally offer a higher current yield than is offered by higher
grade municipal securities, but they also generally involve greater price
volatility and greater credit and market risk. Credit risk relates to the
issuer's ability to make timely payment of interest and principal when due.
Market risk relates to the changes in market value that occur as a result of
variation in the level of prevailing interest rates and yield relationships in
the municipal securities market. Debt securities rated BB or below by S&P and Ba
or below by Moody's are commonly referred to as "junk bonds." Although the Fund
primarily will invest in medium and lower grade municipal securities, the Fund
may invest in higher grade municipal securities for temporary defensive
purposes. Such investments may result in lower current income than if the Fund
were fully invested in medium and lower grade securities.
 
  The value of the Fund's portfolio securities can be expected to fluctuate over
time. When interest rates decline, the value of a portfolio invested in fixed
income securities generally can be expected to rise. Conversely, when interest
rates rise, the value of a portfolio invested in fixed income securities
generally can be expected to decline. However, the secondary market prices of
medium and lower grade municipal securities are less sensitive to changes in
interest rates and are more sensitive to adverse economic changes or individual
issuer developments than are the secondary market prices of higher grade debt
securities. A significant increase in interest rates or a general economic
downturn could severely disrupt the market for medium and lower grade municipal
securities and adversely affect the market value of such securities. Such events
also could lead to a higher incidence of defaults by issuers of medium and lower
grade municipal securities as compared with historical default rates. In
addition, changes in interest rates and periods of economic uncertainty can be
expected to result in increased volatility in the market price of the municipal
securities in the Fund's portfolio and thus in the net asset value of the
 
                                       17
<PAGE>   34
 
Fund. Also, adverse publicity and investor perceptions, whether or not based on
rational analysis, may affect the value and liquidity of medium and lower grade
municipal securities. The secondary market value of municipal securities
structured as zero coupon securities and payment-in-kind securities may be more
volatile in response to changes in interest rates than debt securities which pay
interest periodically in cash. Investment in such securities also involves
certain tax considerations. See "Tax Status."
 
  Increases in interest rates and changes in the economy may adversely affect
the ability of issuers of medium and lower grade municipal securities to pay
interest and to repay principal, to meet projected financial goals and to obtain
additional financing. In the event that an issuer of securities held by the Fund
experiences difficulties in the timely payment of principal or interest and such
issuer seeks to restructure the terms of its borrowings, the Fund may incur
additional expenses and may determine to invest additional assets with respect
to such issuer or the project or projects to which the Fund's portfolio
securities relate. Further, the Fund may incur additional expenses to the extent
that it is required to seek recovery upon a default in the payment of interest
or the repayment of principal on its portfolio holdings, and the Fund may be
unable to obtain full recovery thereof.
 
  To the extent that there is no established retail market for some of the
medium or lower grade municipal securities in which the Fund may invest, trading
in such securities may be relatively inactive. The Adviser is responsible for
determining the net asset value of the Fund, subject to the supervision of the
Board of Trustees of the Trust. During periods of reduced market liquidity and
in the absence of readily available market quotations for medium and lower grade
municipal securities held in the Fund's portfolio, the ability of the Adviser to
value the Fund's securities becomes more difficult and the Adviser's use of
judgment may play a greater role in the valuation of the Fund's securities due
to the reduced availability of reliable objective data. The effects of adverse
publicity and investor perceptions may be more pronounced for securities for
which no established retail market exists as compared with the effects on
securities for which such a market does exist. Further, the Fund may have more
difficulty selling such securities in a timely manner and at their stated value
than would be the case for securities for which an established retail market
does exist.
 
   
  The Adviser seeks to minimize the risks involved in investing in medium and
lower grade municipal securities through portfolio diversification, careful
investment analysis, and attention to current developments and trends in the
economy and financial and credit markets. The Fund will rely on the Adviser's
judgment, analysis and experience in evaluating the creditworthiness of an
issue. In its analysis, the Adviser will take into consideration, among other
things, the issuer's financial resources, its sensitivity to economic conditions
and trends, its operating history, the quality of the issuer's management and
regulatory matters. The Adviser may consider the credit ratings of Moody's and
S&P in evaluating municipal securities, although it does not rely primarily on
these ratings. Such ratings evaluate
    
 
                                       18
<PAGE>   35
 
only the safety of principal and interest payments, not market value risk.
Additionally, because the creditworthiness of an issuer may change more rapidly
than is able to be timely reflected in changes in credit ratings, the Adviser
continuously monitors the issuers of municipal securities held in the Fund's
portfolio.
 
  Municipal securities generally are not listed for trading on any national
securities exchange, and many issuers of medium and lower grade municipal
securities choose not to have a rating assigned to their obligations by any
nationally recognized statistical rating organization. The amount of information
available about the financial condition of an issuer of unlisted or unrated
securities generally is not as extensive as that which is available with respect
to issuers of listed or rated securities. Because of the nature of medium and
lower rated municipal securities, achievement by the Fund of its investment
objective may be more dependent on the credit analysis of the Adviser than is
the case for an investment company which invests primarily in exchange listed,
higher grade securities.
 
   
  SPECIAL CONSIDERATIONS REGARDING CERTAIN MUNICIPAL SECURITIES. The Fund may
invest in zero coupon and payment-in-kind municipal securities. Zero coupon
securities are debt obligations that do not entitle the holder to any periodic
payment of interest prior to maturity or a specified date when the securities
begin paying current interest. They are issued and traded at a discount from
their face amounts or par value, which discount varies depending on the time
remaining until cash payments begin, prevailing interest rates, liquidity of the
security and the perceived credit quality of the issuer. The Internal Revenue
Code of 1986, as amended (the "Code"), requires that regulated investment
companies distribute at least 90% of their net investment income each year,
including tax-exempt and non-cash income. Accordingly, although the Fund will
receive no coupon payments on zero coupon securities prior to their maturity,
the Fund is required, in order to maintain its desired tax treatment, to include
in its distributions to shareholders in each year any income attributable to
zero coupon securities that is in excess of 10% of the Fund's net investment
income in that year. The Fund may be required to borrow or to liquidate
portfolio securities at a time that it otherwise would not have done so in order
to make such distributions. Payment-in-kind securities are securities that pay
interest through the issuance of additional securities. Such securities
generally are more volatile in response to changes in interest rates and are
more speculative investments than are securities that pay interest periodically
in cash. As of December 31, 1996, approximately 3.79% and 0.04% of the Fund's
total net assets were invested in zero coupon securities and payment-in-kind
securities, respectively.
    
 
  The Fund may invest in derivative municipal income securities such as inverse
floaters, range floaters and capped floaters. Investment in such securities
involves special risks as compared to investment in conventional floating or
variable rate municipal income securities. The extent of increases and decreases
in the value of such securities and the corresponding changes to the per share
net asset value of the Fund in response to changes in market rates of interest
generally will be larger than
 
                                       19
<PAGE>   36
 
comparable changes in the value of an equal principal amount of a fixed rate
income security having similar credit quality, redemption provisions and
maturity. The markets for such securities may be less developed than the markets
for conventional floating or variable rate municipal income securities.
 
- ------------------------------------------------------------------------------
INVESTMENT PRACTICES
- ------------------------------------------------------------------------------
 
  In connection with the investment policies described above, the Fund also may
engage in strategic transactions and purchase and sell securities on a "when
issued" and "delayed delivery" basis. These investments entail risk. Strategic
transactions generally will not be treated as investments in tax-exempt
municipal securities for purposes of the Fund's investment policy with respect
thereto.
 
  STRATEGIC TRANSACTIONS. The Fund may purchase and sell derivative instruments
such as exchange-listed and over-the-counter put and call options on securities,
financial futures, fixed-income indices and other financial instruments,
purchase and sell financial futures contracts and enter into various interest
rate transactions such as swaps, caps, floors or collars. Collectively, all of
the above are referred to as "Strategic Transactions." Strategic Transactions
may be used to attempt to protect against possible changes in the market value
of securities held in or to be purchased for the Fund's portfolio resulting from
securities markets, to protect the Fund's unrealized gains in the value of its
portfolio securities, to facilitate the sale of such securities for investment
purposes, to manage the effective maturity or duration of the Fund's portfolio,
or to establish a position in the derivatives markets as a temporary substitute
for purchasing or selling particular securities. Any or all of these investment
techniques may be used at any time and there is no particular strategy that
dictates the use of one technique rather than another, as use of any Strategic
Transaction is a function of numerous variables including market conditions. The
ability of the Fund to utilize these Strategic Transactions successfully will
depend on the Adviser's ability to predict pertinent market movements, which
cannot be assured. The Fund will comply with applicable regulatory requirements
when implementing these strategies, techniques and instruments. Strategic
Transactions involving financial futures and options thereon will be purchased,
sold or entered into only for bona fide hedging, risk management or portfolio
management purposes and not for speculative purposes.
 
  Strategic Transactions have risks associated with them including possible
default by the other party to the transaction, illiquidity and, to the extent
the Adviser's view as to certain market movements is incorrect, the risk that
the use of such Strategic Transactions could result in losses greater than if
they had not been used. Use of put and call options may result in losses to the
Fund, force the sale of portfolio securities at inopportune times or for prices
other than at current market values, limit the amount of appreciation the Fund
can realize on its investments or cause the Fund to hold a security it might
otherwise sell. The use of options and futures transactions entails certain
other risks. In particular, the variable degree of
 
                                       20
<PAGE>   37
 
correlation between price movements of futures contracts and price movements in
the related portfolio position of the Fund creates the possibility that losses
on the hedging instrument may be greater than gains in the value of the Fund's
position. In addition, futures and options markets may not be liquid in all
circumstances and certain over-the-counter options may have no markets. As a
result, in certain markets, the Fund might not be able to close out a
transaction without incurring substantial losses, if at all. Although the
contemplated use of these futures contracts and options thereon should tend to
minimize the risk of loss due to a decline in the value of the hedged position,
at the same time they tend to limit any potential gain which might result from
an increase in value of such position. Finally, the daily variation margin
requirements for futures contracts would create a greater ongoing potential
financial risk than would purchases of options, where the exposure is limited to
the cost of the initial premium. Losses resulting from the use of Strategic
Transactions would reduce net asset value, and possibly income, and such losses
can be greater than if the Strategic Transactions had not been utilized. The
Strategic Transactions that the Fund may use and some of their risks are
described more fully in the Fund's Statement of Additional Information.
 
  Income earned or deemed to be earned, if any, by the Fund from its Strategic
Transactions will be distributed to its shareholders in taxable distributions.
See "Tax Status."
 
   
  "WHEN ISSUED" AND "DELAYED DELIVERY" TRANSACTIONS. The Fund may also purchase
and sell municipal securities on a "when issued" and "delayed delivery" basis.
No income accrues to the Fund on municipal securities in connection with such
transactions prior to the date the Fund actually takes delivery of such
securities. These transactions are subject to market fluctuation; the value of
the municipal securities at delivery may be more or less than their purchase
price, and yields generally available on municipal securities when delivery
occurs may be higher than yields on the municipal securities obtained pursuant
to such transactions. Because the Fund relies on the buyer or seller, as the
case may be, to consummate the transaction, failure by the other party to
complete the transaction may result in the Fund missing the opportunity of
obtaining a price or yield considered to be advantageous. When the Fund is the
buyer in such a transaction, however, it will maintain, in a segregated account
with its custodian, cash or liquid securities having an aggregate value equal to
the amount of such purchase commitments until payment is made. The Fund will
make commitments to purchase municipal securities on such basis only with the
intention of actually acquiring these securities, but the Fund may sell such
securities prior to the settlement date if such sale is considered to be
advisable. No specific limitation exists as to the percentage of the Fund's
assets which may be used to acquire securities on a "when issued" or "delayed
delivery" basis. To the extent the Fund engages in "when issued" and "delayed
delivery" transactions, it will do so for the purpose of acquiring securities
for the Fund's portfolio consistent with its investment objective and policies
and not for the purpose of investment leverage.

  OTHER PRACTICES. The Fund has no restrictions on the maturity of municipal
bonds in which it may invest. The Fund will seek to invest in municipal bonds of
such maturities that, in the judgment of the Fund and the Adviser, will provide
a high level of current income consistent with liquidity requirements and market
conditions.
 
  The Fund may borrow amounts up to 5% of its net assets in order to pay for
redemptions when liquidation of portfolio securities is considered
disadvantageous or inconvenient and may pledge up to 10% of its net assets to
secure such borrowings.
 
  It is possible that the Fund will invest more than 25% of its assets in a
particular segment of the municipal bond market, such as Hospital Revenue Bonds,
Housing Agency Bonds, Airport Bonds or Industrial Development Bonds. In such
circumstances, economic, business, political or other changes affecting one bond
might also affect other bonds in the same segment, thereby potentially
increasing market risk with respect to the bonds in such segment. Such changes
could include, but are not limited to, proposed or suggested legislation
involving the financing of projects within such segments, declining markets or
needs for such projects and shortages or price increases of materials needed for
such projects.
 
  PORTFOLIO TRANSACTIONS AND BROKERAGE ALLOCATION.  In effecting purchases and
sales of the Fund's portfolio securities, the Adviser and the Fund may place
orders with and pay brokerage commissions to brokers, including brokers which
may be affiliated with the Fund, the Adviser, the Distributor or dealers
participating in the offering of the Fund's shares. In addition, in selecting
among firms to handle a particular transaction, the Adviser and the Fund may
take into account whether the firm has sold or is selling shares of the Fund.

- ------------------------------------------------------------------------------
ALTERNATIVE SALES ARRANGEMENTS
- ------------------------------------------------------------------------------
 
  The Alternative Sales Arrangements permit an investor to choose the method of
purchasing shares that is more beneficial to the investor, taking into account
the amount of the purchase, the length of time the investor expects to hold the
shares, whether the investor wishes to receive dividends in cash or to reinvest
them in additional shares of the Fund, and other circumstances. Investors should
consider such factors together with the amount of sales charges and accumulated
distribution and service fees with respect to each class of shares that may be
incurred over the anticipated duration of their investment in the Fund.
 
  The Fund offers three classes of shares, designated Class A Shares, Class B
Shares and Class C Shares. Shares of each class are offered at a price equal to
their net asset value per share plus a sales charge which, at the election of
the purchaser, may be imposed (a) at the time of purchase ("Class A Shares") or
(b) on a contingent deferred basis (Class A Share accounts over $1 million,
"Class B Shares" and "Class C Shares"). Class A Share accounts over $1 million
or otherwise subject to a contingent deferred sales charge ("CDSC"), Class B
Shares and Class C Shares sometimes are referred to herein collectively as
"Contingent Deferred Sales Charge Shares" or "CDSC Shares."
 
  The minimum initial investment with respect to each class of shares is $500.
The minimum subsequent investment with respect to each class of shares is $25.
It is presently the policy of the Distributor not to accept any order for Class
B Shares in an amount of $500,000 or more and not to accept any order for Class
C Shares in an
 
                                       24
<PAGE>   41
 
amount of $1 million or more because it ordinarily will be more advantageous for
an investor making such an investment to purchase Class A Shares.
 
  An investor should carefully consider the sales charges applicable to each
class of shares and the estimated period of their investment to determine which
class of shares is more beneficial for the investor to purchase. For example,
investors who would qualify for a significant purchase price discount from the
maximum sales charge on Class A Shares may determine that payment of such a
reduced front-end sales charge is superior to electing to purchase Class B
Shares or Class C Shares, each with no front-end sales charge but subject to a
CDSC and a higher aggregate distribution and service fee. However, because
initial sales charges are deducted at the time of purchase of Class A Share
accounts under $1 million, a purchaser of such Class A Shares would not have all
of his or her funds invested initially and, therefore, would initially own fewer
shares than if Class B Shares or Class C Shares had been purchased. On the other
hand, an investor whose purchase would not qualify for price discounts
applicable to Class A Shares and intends to remain invested until after the
expiration of the applicable CDSC may wish to defer the sales charge and have
all his or her funds initially invested in Class B Shares or Class C Shares. If
such an investor anticipates that he or she will redeem such shares prior to the
expiration of the CDSC period applicable to Class B Shares, the investor may
wish to acquire Class C Shares. Investors must weigh the benefits of deferring
the sales charge and having all of their funds invested against the higher
aggregate distribution and service fee applicable to Class B Shares and Class C
Shares (discussed below).
 
  Each class of shares represents an interest in the same portfolio of
investments of the Fund and has the same rights, except each class of shares (i)
bears those distribution fees, service fees and administrative expenses
applicable to the respective class of shares as a result of its sales
arrangements, (ii) has exclusive voting rights with respect to those provisions
of the Fund's Rule 12b-1 distribution plan which relate only to such class and
(iii) has a different exchange privilege. Generally, a class of shares subject
to a higher ongoing distribution and service fee or subject to the conversion
feature will have a higher expense ratio and pay lower dividends than a class of
shares subject to a lower ongoing distribution and service fee or not subject to
the conversion feature. The per share net asset values of the different classes
of shares are expected to be substantially the same; from time to time, however,
the per share net asset values of the classes may differ. The net asset value
per share of each class of shares of the Fund will be determined as described in
this Prospectus under "Purchase of Shares -- Net Asset Value."
 
   
  The administrative expenses that may be allocated to a specific class of
shares may consist of (i) ACCESS' expenses attributable to a specific class of
shares, which expenses typically will be higher with respect to classes of
shares subject to the conversion feature; (ii) printing and postage expenses
related to preparing and distributing materials such as shareholder reports,
prospectuses and proxy statements to current shareholders of a specific class;
(iii) Securities and Exchange
    
 
                                       25
<PAGE>   42
 
Commission (the "SEC") registration fees incurred by a class of shares; (iv) the
expense of administrative personnel and services as required to support the
shareholders of a specific class; (v) Trustees' fees or expense incurred as a
result of issues relating to one class of shares; (vi) accounting expenses
relating solely to one class of shares; and (vii) any other incremental expenses
subsequently identified that should be properly allocated to one or more classes
of shares. All such expenses incurred by a class will be borne on a pro rata
basis by the outstanding shares of such class. All allocations of administrative
expenses to a particular class of shares will be limited to the extent necessary
to preserve the Fund's qualification as a regulated investment company under the
Code.
 
- ------------------------------------------------------------------------------
PURCHASE OF SHARES
- ------------------------------------------------------------------------------
 
   
  The Fund offers three classes of shares for sale to the public on a continuous
basis through the Distributor, as principal underwriter, which is located at One
Parkview Plaza, Oakbrook Terrace, Illinois 60181. Shares also are offered
through members of the National Association of Securities Dealers, Inc. ("NASD")
acting as securities dealers ("dealers") and through NASD members acting as
brokers for investors ("brokers") or eligible non-NASD members acting as agents
for investors ("financial intermediaries"). The Fund reserves the right to
suspend or terminate the continuous public offering of its shares at any time
and without prior notice.
    
 
  The Fund's shares are offered at the net asset value per share next computed
after an investor places an order to purchase directly with the investor's
broker, dealer or financial intermediary or with the Distributor plus any
applicable sales charge. Sales personnel of brokers, dealers and financial
intermediaries distributing the Fund's shares may receive differing compensation
for selling different classes of shares. It is the responsibility of the
investor's broker, dealer or financial intermediary to transmit the order to the
Distributor. Because the Fund generally will determine net asset value once each
business day as of the close of business, purchase orders placed through an
investor's broker, dealer or financial intermediary must be transmitted to the
Distributor by such broker, dealer or financial intermediary prior to such time
in order for the investor's order to be fulfilled on the basis of the net asset
value to be determined that day. Any change in the purchase price due to the
failure of the Distributor to receive a purchase order prior to such time must
be settled between the investor and the broker, dealer or financial intermediary
submitting the order.
 
  The Distributor may from time to time implement programs under which a broker,
dealer or financial intermediary's sales force may be eligible to win nominal
awards for certain sales efforts or under which the Distributor will reallow to
any broker, dealer or financial intermediary that sponsors sales contests or
recognition programs conforming to criteria established by the Distributor, or
participates in sales programs sponsored by the Distributor, an amount not
exceeding the total applicable sales charges on the sales generated by the
broker, dealer or financial
 
                                       26
<PAGE>   43
 
   
intermediary at the public offering price during such programs. Other programs
provide, among other things and subject to certain conditions, for certain
favorable distribution arrangements for shares of the Fund. Also, the
Distributor in its discretion may from time to time, pursuant to objective
criteria established by it, pay fees to, and sponsor business seminars for,
qualifying brokers, dealers or financial intermediary for certain services or
activities which are primarily intended to result in sales of shares of the
Fund. Fees may include payment for travel expenses, including lodging, incurred
in connection with trips taken by invited registered representatives and members
of their families to locations within or outside of the United States for
meetings or seminars of a business nature. In some instances additional
compensation or promotional incentives may be offered to brokers, dealers or
financial intermediaries that have sold or may sell significant amounts of
shares during specified periods of time. The Distributor may provide additional
compensation to Edward D. Jones & Co. or an affiliate thereof based on a
combination of its sales of shares and increases in assets under management.
Such payments to brokers, dealers and financial intermediaries for sales
contests, other sales programs and seminars are made by the Distributor out of
its own assets and not out of the assets of the Fund. Such fees paid for such
services and activities with respect to the Fund will not exceed in the
aggregate 1.25% of the average total daily net assets of the Fund on an annual
basis. These programs will not change the price an investor will pay for shares
or the amount that the Fund will receive from such sale.
    
 
CLASS A SHARES
 
  The public offering price of Class A Shares is equal to the net asset value
per share plus an initial sales charge which is a variable percentage of the
offering price depending upon the amount of the sale. The table below shows
total sales charges and dealer concessions reallowed to dealers and agency
commissions paid to brokers with respect to sales of Class A Shares. The sales
charge is allocated between the investor's broker, dealer or financial
intermediary and the Distributor. As indicated previously, at the discretion of
the Distributor, the entire sales charge may be reallowed to such broker, dealer
or financial intermediary. The staff of the SEC has taken the position that
brokers, dealers or financial intermediaries who receive more than 90% or more
of the sales charge may be deemed to be "underwriters" as that term is defined
in the Securities Act of the 1933, as amended.

* No sales charge is payable at the time of purchase on investments of $1
  million or more, although for such investments the Fund imposes a CDSC of
  1.00% on redemptions made within one year of the purchase. A commission will
  be paid to brokers, dealers or financial intermediaries who initiate and are
  responsible for purchases of $1 million or more as follows: 1.00% on sales
  to $2 million, plus 0.80% on the next $1 million and 0.50% on the excess
  over $3 million. See "Purchase of Shares -- Deferred Sales Charge
  Alternatives" for additional information with respect to CDSCs.
    
 
QUANTITY DISCOUNTS
 
  Investors purchasing Class A Shares may, under certain circumstances, be
entitled to pay reduced sales charges. The circumstances under which such
investors may pay reduced sales charges are described below.
 
  Investors, or their brokers, dealers or financial intermediaries, must notify
the Fund whenever a quantity discount is applicable to purchases. Upon such
notification, an investor will receive the lowest applicable sales charge.
Quantity discounts may be modified or terminated at any time. For more
information about quantity discounts, investors should contact their broker,
dealer or financial intermediary or the Distributor.
 
   
  A person eligible for a reduced sales charge includes an individual, their
spouse and minor children under 21 years of age and any corporation,
partnership, or sole proprietorship which is 100% owned, either alone or in
combination by any of the foregoing; a trustee or other fiduciary of a single
trust estate or a single fiduciary account; or a "company" as defined is section
2(a)(8) of the 1940 Act.
    
 
   
  As used herein, "Participating Funds" refers to certain open-end investment
companies advised by the Adviser or Van Kampen American Capital Asset
Management, Inc. and distributed by the Distributor. Additional funds may be
added from time to time as determined by the Fund's Board of Trustees as
Participating Funds.
    
 
   
  VOLUME DISCOUNTS. The size of investment shown in the preceding sales charge
table applies to the total dollar amount being invested by any person at any one
time in Class A Shares of the Fund, or in any combination of shares of the Fund
and
    
 
                                       28
<PAGE>   45
 
   
shares of other Participating Funds, although other Participating Funds may have
different sales charges.
    
 
   
  CUMULATIVE PURCHASE DISCOUNT. The size of investment shown in the preceding
sales charge table may also be determined by combining the amount being invested
in Class A Shares of the Fund with other shares of the Fund and shares of
Participating Funds, plus the current offering price of all shares of the Fund
and other Participating Funds which have been previously purchased and are still
owned.
    
 
   
  LETTER OF INTENT. A Letter of Intent provides an opportunity for an investor
to obtain a reduced sales charge by aggregating the amount being invested over a
13-month period to determine the sales charge as outlined in the preceding sales
charge table. The size of investment shown in the preceding table includes the
amount of intended purchases of Class A Shares of the Fund with other shares of
the Fund and shares of the Participating Funds plus the value of all shares of
the Fund and other Participating Funds previously purchased during such 13-month
period and still owned. An investor may elect to compute the 13-month period
starting up to 90 days before the date of execution of a Letter of Intent. Each
investment made during the period receives the reduced sales charge applicable
to the total amount of the investment goal. If trades not initially made under a
Letter of Intent subsequently qualify for a lower sales charge through the
90-day back-dating provision, an adjustment will be made at the expiration of
the Letter of Intent to give effect to the lower charge. If the goal is not
achieved within the 13-month period, the investor must pay the difference
between the sales charge applicable to the purchases made and the sales charges
previously paid. When an investor signs a Letter of Intent, shares equal to at
least 5% of the total purchase amount of the level selected will be restricted
from sale or redemption by the investor until the Letter of Intent is satisfied
or any additional sales charges have been paid; if the Letter of Intent is not
satisfied by the investor and any additional sales charges are not paid,
sufficient restricted shares will be redeemed by the Fund to pay such charges.
Additional information is contained in the application accompanying this
Prospectus.
    
 
OTHER PURCHASE PROGRAMS
 
   
  Purchasers of Class A Shares may be entitled to reduced initial sales charges
in connection with unit investment trust reinvestment programs and purchases by
registered representatives of selling firms or purchases by persons affiliated
with the Fund or the Distributor. The Fund reserves the right to modify or
terminate these arrangements at any time.
    
 
  UNIT INVESTMENT TRUST REINVESTMENT PROGRAMS. The Fund permits unitholders of
unit investment trusts to reinvest distributions from such trusts in Class A
Shares of the Fund at net asset value with no minimum initial or subsequent
investment requirement if the administrator of an investor's unit investment
trust program meets certain uniform criteria relating to cost savings by the
Fund and the
 
                                       29
<PAGE>   46
 
Distributor. The total sales charge for all other investments made from unit
trust distributions will be 1.00% of the offering price (1.01% of net asset
value). Of this amount, the Distributor will pay to the broker, dealer or
financial intermediary, if any, through which such participation in the
qualifying program was initiated 0.50% of the offering price as a dealer
concession or agency commission. Persons desiring more information with respect
to this program, including the applicable terms and conditions thereof, should
contact their broker, dealer, financial intermediary or the Distributor.
 
   
  The administrator of such a unit investment trust must have an agreement with
the Distributor pursuant to which the administrator will (1) submit a single
bulk order and make payment with a single remittance for all investments in the
Fund during each distribution period by all investors who choose to invest in
the Fund through the program and (2) provide ACCESS with appropriate backup data
for each participating investor in a computerized format fully compatible with
ACCESS' processing system.
    
 
   
  As further requirements for obtaining these special benefits, the Fund also
requires that all dividends and other distributions by the Fund be reinvested in
additional shares without any systematic withdrawal program. There will be no
minimum for reinvestments from unit investment trusts. The Fund will send
account activity statements to such participants on a monthly basis only, even
if their investments are made more frequently. The Fund reserves the right to
modify or terminate this program at any time.
    
 
  NAV PURCHASE OPTIONS. Class A Shares of the Fund may be purchased at net asset
value, upon written assurance that the purchase is made for investment purposes
and that the shares will not be resold except through redemption by the Fund,
by:
 
   
  (1) Current or retired trustees or directors of funds advised by the Adviser
      or Van Kampen American Capital Asset Management, Inc. and such persons'
      families and their beneficial accounts.
    
 
   
  (2) Current or retired directors, officers and employees of Morgan Stanley
      Group Inc. and any of its subsidiaries, employees of an investment
      subadviser to any fund described in (1) above or an affiliate of such
      subadviser; and such persons' families and their beneficial accounts.
    
 
   
  (3) Directors, officers, employees and registered representatives of financial
      institutions that have a selling group agreement with the Distributor and
      their spouses and children under 21 years of age when purchasing for any
      accounts they beneficially own, or, in the case of any such financial
      institution, when purchasing for retirement plans for such institution's
      employees.
    
 
  (4) Registered investment advisers, trust companies and bank trust departments
      investing on their own behalf or on behalf of their clients provided that

      aggregate amount invested in Class A Shares of the Fund alone, or any
      combination of shares of the Fund and shares of other Participating Funds
      as described herein under "Purchase of Shares -- Class A Shares --
      Quantity Discounts," during the 13-month period commencing with the first
      investment pursuant hereto equals at least $1 million. The Distributor may
      pay brokers, dealers or financial intermediaries through which purchases
      are made an amount up to 0.50% of the amount invested, over a 12-month
      period following such transaction.
    
 
   
  (5) Trustees and other fiduciaries purchasing shares for retirement plans of
      organizations with retirement plan assets of $3 million or more and which
      invest in multiple fund families through national wirehouse alliance
      programs.
    
 
  (6) Accounts as to which a broker, dealer or financial intermediary charges an
      account management fee ("wrap accounts"), provided the broker, dealer or
      financial intermediary has a separate agreement with the Distributor.
 
  (7) Investors purchasing shares of the Fund with redemption proceeds from
      other mutual fund complexes on which the investor has paid a front-end
      sales charge or was subject to a deferred sales charge, whether or not
      paid, if such redemption has occurred no more than 30 days prior to such
      purchase.
 
   
  (8) Trusts created under pension, profit sharing or other employee benefit
      plans qualified under Section 401(a) of the Code, or custodial accounts
      held by a bank created pursuant to Section 403(b) of the Code and
      sponsored by non-profit organizations defined under Section 501(c)(3) of
      the Code and assets held by an employer or trustee in connection with an
      eligible deferred compensation plan under Section 457 of the Code. Such
      plans will qualify for purchases at net asset value provided, for plans
      initially establishing accounts with the Distributor in the Participating
      Funds after February 1, 1997, that (1) the initial amount invested in the
      Participating Funds is at least $500,000 or (2) such shares are purchased
      by an employer sponsored plan with more than 100 eligible employees. Such
      plans that have been established with a Participating Fund or have
      received proposals from the Distributor prior to February 1, 1997 based on
      net asset value purchase privileges previously in effect will be qualified
      to purchase shares of the Participating Funds at net asset value for
      accounts established on or before May 1, 1997. Section 403(b) and similar
      accounts for which Van Kampen American Capital Trust Company served as
      custodian will not be eligible for net asset value purchases based on the
      aggregate investment made by the plan or the number of eligible employees,
      except under certain uniform criteria established by the Distributor from
      time to time. Prior to February 1, 1997, a commission will be paid to
      authorized dealers who initiate and are responsible for such purchases
      within a rolling twelve-month period as follows: 1.00% on sales to $5
      million, plus 0.50% on the next $5 million and 0.25% on the excess over
      $10 million. For purchases on February 1, 1997
    
 
                                       31
<PAGE>   48
 
   
      and thereafter, a commission will be paid as follows: 1.00% on sales to $2
      million, plus 0.80% on the next $1 million, plus 0.50% on the next $47
      million and 0.25% on the excess over $50 million.
    
 
   
  (9) Individuals who are members of a "qualified group". For this purpose, a
      qualified group is one which (i) has been in existence for more than six
      months, (ii) has a purpose other than to acquire shares of the Fund or
      similar investments, (iii) has given and continues to give its endorsement
      or authorization, on behalf of the group, for purchase of shares of the
      Fund and other Participating Funds, (iv) has a membership that the
      authorized dealer can certify as to the group's members and (v) satisfies
      other uniform criteria established by the Distributor for the purpose of
      realizing economics of scale in distributing such shares. A qualified
      group does not include one whose sole organizational nexus, for example,
      is that its participants are credit card holders of the same institution,
      policy holders of an insurance company, customers of a bank or
      broker-dealer, clients of an investment adviser or other similar groups.
      Shares purchased in each group's participants account in connection with
      this privilege will be subject to a CDSC of 1.00% in the event of
      redemption within one year of purchase, and a commission will be paid to
      authorized dealers who initiate and are responsible for such sales to each
      individual as follows: 1.00% on sales to $2 million, plus 0.80% on the
      next $1 million and 0.50% on the excess over $3 million.
    
 
   
The term "families" includes a person's spouse, children under 21 years of age
and grandchildren, parents, and a person's spouse's parents.
    
 
   
  Purchase orders made pursuant to clause (4) may be placed either through
authorized brokers, dealers or financial intermediaries as described above or
directly with ACCESS, the investment adviser, trust company or bank trust
department, provided that ACCESS receives federal funds for the purchase by the
close of business on the next business day following acceptance of the order. An
authorized broker, dealer or financial intermediary may charge a transaction fee
for placing an order to purchase shares pursuant to this provision or for
placing a redemption order with respect to such shares. The Fund may terminate,
or amend the terms of, offering shares of the Fund at net asset value to such
groups at any time.
    
 
DEFERRED SALES CHARGE ALTERNATIVES
 
  Investors choosing the deferred sales charge alternative may purchase Class A
Shares in an amount of $1 million or more, Class B Shares or Class C Shares. The
public offering price of a CDSC Share is equal to the net asset value per share
without the imposition of a sales charge at the time of purchase. CDSC Shares
are sold without an initial sales charge so that the Fund may invest the full
amount of the investor's purchase payment. The Distributor will compensate
brokers, dealers and financial intermediaries participating in the continuous
public offering of the CDSC Shares out of its own assets, and not out of the
assets of the Fund, at a percentage rate of the dollar value of the CDSC Shares
purchased from the Fund
 
                                       32
<PAGE>   49
 
by such brokers, dealers and financial intermediaries, which percentage rate
will be equal to (i) with respect to Class A Shares, 1.00% on sales to $2
million, plus 0.80% on the next million, plus 0.20% on the next $2 million and
0.08% on the excess over $5 million; (ii) 4.00% with respect to Class B Shares;
and (iii) 1.00% with respect to Class C Shares. Such compensation will not
change the price an investor will pay for CDSC Shares or the amount that the
Fund will receive from such sale.
 
   
  CDSC Shares redeemed within a specified period of time generally will be
subject to a CDSC at the rates set forth below charged as a percentage of the
dollar amount subject thereto. The amount of the CDSC will vary depending on (i)
the class of CDSC Shares to which such shares belong and (ii) the number of
years from the time of payment for the purchase of the CDSC Shares until the
time of their redemption. The charge will be assessed on an amount equal to the
lesser of the then current market value or the original purchase price of the
CDSC Shares being redeemed. Accordingly, no sales charge will be imposed on
increases in net asset value above the initial purchase price. In addition, no
CDSC will be assessed on CDSC Shares derived from reinvestment of dividends or
capital gains distributions. Solely for purposes of determining the number of
years from the time of any payment for the purchase of CDSC Shares, all payments
during a month will be aggregated and deemed to have been made on the last day
of the month.
    
 
   
  Proceeds from the CDSC and the distribution fee applicable to a class of CDSC
Shares are paid to the Distributor and are used by the Distributor to defray its
expenses related to providing distribution related services to the Fund in
connection with the sale of shares of such class of CDSC Shares, such as the
payment of compensation to selected dealers and agents for selling such shares.
The combination of the CDSC and the distribution fees facilitates the ability of
the Fund to sell such CDSC Shares without a sales charge being deducted at the
time of purchase.
    
 
   
  In determining whether a CDSC is applicable to a redemption of CDSC Shares, it
will be assumed that the redemption is made first of any CDSC Shares acquired
pursuant to reinvestment of dividends or distributions, second of CDSC Shares
that have been held for a sufficient period of time such that the CDSC no longer
is applicable to such shares, third of Class A Shares in the shareholder's Fund
account that have converted from Class B Shares or Class C Shares, if any, and
fourth of CDSC Shares held longest during the period of time that a CDSC is
applicable to such CDSC Shares. The charge will not be applied to dollar amounts
representing an increase in the net asset value per share since the time of
purchase.
    
 
  To provide an example, assume an investor purchased 100 Class B Shares at $10
per share (at a cost of $1,000) and in the second year after purchase, the net
asset value per share is $12 and, during such time, the investor has acquired 10
additional Class B Shares upon dividend reinvestment. If at such time the
investor makes his first redemption of 50 shares (proceeds of $600), 10 shares
will not be subject to charge because of dividend reinvestment. With respect to
the remaining 40 shares, the charge is applied only to the original cost of $10
per share and not to the increase in net asset value of $2 per share. Therefore,
$400 of the $600 redemption
 
                                       33
<PAGE>   50
 
proceeds will be charged at a rate of 3.75% (the applicable rate in the second
year after purchase).
 
   
  CLASS A SHARE PURCHASES OF $1 MILLION OR MORE. No sales charge is payable at
the time of purchase on investments in Class A Shares of $1 million or more,
although for such investments the Fund imposes a CDSC of 1.00% on redemptions
made within one year of the purchase. A commission will be paid to dealers who
initiate and are responsible for purchases of $1 million or more as follows:
1.00% on sales to $2 million, plus 0.80% on the next $1 million and 0.50% on the
excess over $3 million.
    
 
   
  CLASS B SHARES. Class B Shares redeemed within six years of purchase generally
will be subject to a CDSC at the rates set forth below, charged as a percentage
of the dollar amount subject thereto:

  The CDSC generally is waived on redemptions of Class B Shares made pursuant to
the Systematic Withdrawal Plan. See "Shareholder Services -- Systematic
Withdrawal Plan."
    
 
   
  CLASS C SHARES. Class C Shares redeemed within the first 12 months of purchase
generally will be subject to a CDSC of 1.00% of the dollar amount subject
thereto. Class C Shares redeemed thereafter will not be subject to a CDSC.
    
 
   
  CONVERSION FEATURE. Class B Shares purchased on or after June 1, 1996 and any
dividend reinvestment plan shares received thereon, automatically convert to
Class A Shares eight years after the end of the calendar month in which the
shares were purchased. Class B Shares purchased before June 1, 1996, and any
dividend reinvestment plan shares received thereon, automatically convert to
Class A Shares seven years after the end of the calendar month in which the
shares were purchased. Class C Shares purchased before January 1, 1997, and any
dividend reinvestment plan shares received thereon, automatically convert to
Class A Shares ten years after the end of the calendar month in which such
shares were purchased. Such conversion will be on the basis of the relative net
asset values per share, without the imposition of any sales load, fee or other
charge.
    
 
   
  The conversion of such shares to Class A Shares is subject to the continuing
availability of an opinion of counsel to the effect that (i) the assessment of
the
    
 
                                       34
<PAGE>   51
 
   
higher distribution and service fees and ACCESS costs with respect to such
shares does not result in the Fund's dividends or distributions constituting
"preferential dividends" under the Code, and (ii) that the conversion of such
shares does not constitute a taxable event under federal income tax law. The
conversion of Shares may be suspended if such an opinion is no longer available
and such shares might continue to be subject to the higher aggregate fees
applicable to such class of shares for an indefinite period.
    
 
   
  WAIVER OF CONTINGENT DEFERRED SALES CHARGE.  The CDSC is waived on redemptions
of Class B Shares and Class C Shares (i) following the death or disability (as
defined in the Code) of a shareholder, (ii) in connection with required minimum
distributions from an IRA or other retirement plan, (iii) pursuant to the Fund's
systematic withdrawal plan but limited to 12% annually of the initial value of
the account, and (iv) effected pursuant to the right of the Fund to liquidate a
shareholder's account as described herein under "Redemption of Shares." The CDSC
also is waived on redemption of Class C Shares as it relates to the reinvestment
of redemption proceeds in shares of the same class of the Fund within 120 days
after redemption. See "Shareholder Services" and "Redemption of Shares" for
further discussion of the waiver provisions.
    
 
NET ASSET VALUE
 
  The net asset value per share of the Fund is determined by calculating the
total value of the Fund's assets, deducting its total liabilities, and dividing
the result by the number of shares of the Fund outstanding. The net asset value
is computed once daily as of 5:00 p.m. Eastern time, Monday through Friday,
except on customary business holidays, or except on any day on which no purchase
or redemption orders are received, or there is not a sufficient degree of
trading in the Fund's portfolio securities such that the Fund's net asset value
per share might be materially affected. The Fund reserves the right to calculate
the net asset value and to adjust the public offering price based thereon more
frequently than once a day if deemed desirable.
 
  Fixed income securities are valued by using market quotations, prices provided
by market makers or estimates of market values obtained from yield data relating
to instruments or securities with similar characteristics in accordance with
procedures established in good faith by the Trustees of the Trust, of which the
Fund is a separate series. Short-term securities with remaining maturities of
less than 60 days are valued at amortized cost when amortized cost is determined
by or under the direction of the Board of Trustees of the Trust to be
representative of the fair value at which it is expected such securities may be
resold. Other assets are valued at fair value as determined in good faith by or
under the direction of the Trustees. The net asset value per share of the
different classes of shares are expected to be substantially the same; from time
to time, however, the per share net asset value of the different classes of
shares may differ.

SHAREHOLDER SERVICES
- ------------------------------------------------------------------------------
 
  The Fund offers a number of shareholder services designed to facilitate
investment in its shares at little or no extra cost to the investor. Below is a
description of such services. Unless otherwise described below, each of these
services may be modified or terminated by the Fund at any time.
 
   
  INVESTMENT ACCOUNT. ACCESS, transfer agent for the Fund and a wholly-owned
subsidiary of Van Kampen American Capital, performs bookkeeping, data processing
and administration services related to the maintenance of shareholder accounts.
Each shareholder has an investment account under which shares are held by
ACCESS. Except as described in this Prospectus, after each share transaction in
an account, the shareholder receives a statement showing the activity in the
account. Each shareholder will receive statements at least quarterly from ACCESS
showing any reinvestments of dividends and capital gains distributions and any
other activity in the account since the preceding statement. Such shareholders
also will receive separate confirmations for each purchase or sale transaction
other than reinvestment of dividends and capital gains distributions and
systematic purchases or redemptions. Additions to an investment account may be
made at any time by purchasing shares through authorized brokers, dealers or
financial intermediaries or by mailing a check directly to ACCESS.
    
 
  SHARE CERTIFICATES. Generally, the Fund will not issue share certificates.
However, upon written or telephone request to the Fund, a share certificate will
be issued, representing shares (with the exception of fractional shares) of the
Fund. A shareholder will be required to surrender such certificates upon
redemption thereof. In addition, if such certificates are lost the shareholder
must write to Van Kampen American Capital Funds, c/o ACCESS, P.O. Box 418256,
Kansas City, MO 64141-9256, requesting an "affidavit of loss" and to obtain a
Surety Bond in a form acceptable to ACCESS. On the date the letter is received
ACCESS will calculate a fee for replacing the lost certificate equal to no more
than 2.00% of the net asset value of the issued shares and bill the party to
whom the replacement certificate was mailed.
 
   
  REINVESTMENT PLAN. A convenient way for investors to accumulate additional
shares is by accepting dividends and capital gains distributions in shares of
the Fund. Such shares are acquired at net asset value per share (without sales
charge) on the record date of such dividend or distribution. Unless the
shareholder instructs otherwise, the reinvestment plan is automatic. This
instruction may be made by telephone by calling (800) 421-5666 ((800) 421-2833
for the hearing impaired) or in writing to ACCESS. The investor may, on the
initial application or prior to any declaration, instruct that dividends be paid
in cash and capital gains distributions be reinvested at net asset value, or
that both dividends and capital gains distributions be paid in cash. For further
information, see "Distributions from the Fund."
    
 
                                       36
<PAGE>   53
 
  AUTOMATIC INVESTMENT PLAN. An automatic investment plan is available under
which a shareholder can authorize ACCESS to charge a bank account on a regular
basis to invest pre-determined amounts in the Fund. Additional information is
available from the Distributor or authorized brokers, dealers or financial
intermediaries.
 
   
  DIVIDEND DIVERSIFICATION. A shareholder may, upon written request or by
completing the appropriate section of the application form accompanied by this
Prospectus or by calling (800) 421-5666 ((800) 421-2833 for the hearing
impaired), elect to have all dividends and other distributions paid on a class
of shares of the Fund invested into shares of the same class of any other
Participating Fund, Tax Free Money Fund or Reserve Fund so long as a
pre-existing account for such class of shares exists for such shareholder.
    
 
  If the qualified pre-existing account does not exist, the shareholder must
establish a new account subject to minimum investment and other requirements of
the fund into which distributions would be invested. Distributions are invested
into the selected fund at its net asset value as of the payable date of the
distribution only if shares of such selected fund have been registered for sale
in the investor's state.
 
   
  EXCHANGE PRIVILEGE. Shares of the Fund may be exchanged with shares of another
Participating Fund subject to certain limitations. Before effecting an exchange,
shareholders in the Fund should obtain and read a current prospectus of the fund
into which the exchange is to be made. SHAREHOLDERS MAY ONLY EXCHANGE INTO SUCH
OTHER FUNDS AS ARE LEGALLY AVAILABLE FOR SALE IN THEIR STATE.
    
 
  To be eligible for exchange, shares of the Fund must have been registered in
the shareholder's name for at least 30 days prior to an exchange. Shares of the
Fund registered in a shareholder's name for less than 30 days may only be
exchanged upon receipt of prior approval of the Adviser. Under normal
circumstances, it is the policy of the Adviser not to approve such requests.
 
  Class A Shares of Van Kampen American Capital funds that generally impose an
initial sales charge are not subject to any sales charge upon exchange into the
Fund. Class A Shares of Van Kampen American Capital funds that generally do not
impose an initial sales charge are subject to the appropriate sales charge
applicable to Class A Shares of the Fund.
 
   
  No sales charge is imposed upon the exchange of Class B Shares and Class C
Shares. The CDSC schedule and conversion schedule applicable to a Class B Share
or Class C Share acquired through the exchange privilege is determined by
reference to the Van Kampen American Capital fund from which such share
originally was purchased. The holding period of a Class B Share or Class C Share
acquired through the exchange privilege is determined by reference to the date
such share originally was purchased from a Van Kampen American Capital fund.
    
 
  Exchanges of shares are sales and may result in a gain or loss for federal
income tax purposes. If the shares exchanged have been held for less than 91
days, the sales
 
                                       37
<PAGE>   54
 
charge paid on such shares is not included in the tax basis of the exchanged
shares, but is carried over and included in the tax basis of the shares
acquired.
 
   
  A shareholder wishing to make an exchange may do so by sending a written
request to ACCESS or by contacting the telephone transaction line at (800)
421-5684 ((800) 421-2833 for the hearing impaired). A shareholder automatically
has telephone exchange privileges unless otherwise designated in the application
form accompanied by this Prospectus. The exchange will take place at the
relative net asset values of the shares next determined after receipt of such
request with adjustment for any additional sales charge. Any shares exchanged
begin earning dividends on the next business day after the exchange is affected.
Van Kampen American Capital and its subsidiaries, including ACCESS
(collectively, "VKAC"), and the Fund employ procedures considered by them to be
reasonable to confirm that instructions communicated by telephone are genuine.
Such procedures include requiring certain personal identification information
prior to acting upon telephone instructions, tape recording telephone
communications, and providing written confirmation of instructions communicated
by telephone. Exchanges are effected at the net asset value per share next
calculated after the request is received in good order with adjustment for any
additional sales charge. If reasonable procedures are employed, a shareholder
agrees that neither VKAC nor the Fund will be liable for following telephone
instructions which it reasonably believes to be genuine. VKAC and the Fund may
be liable for any losses due to unauthorized or fraudulent instructions if
reasonable procedures are not followed. If the exchanging shareholder does not
have an account in the fund whose shares are being acquired, a new account will
be established with the same registration, dividend and capital gains options
(except dividend diversification options) and broker, dealer or financial
intermediary of record as the account from which shares are exchanged, unless
otherwise specified by the shareholder. In order to establish a systematic
withdrawal plan for the new account or reinvest dividends from the new account
into another fund, an exchanging shareholder must file a specific written
request. The Fund reserves the right to reject any order to acquire its shares
through exchange. In addition, the Fund may modify, restrict or terminate the
exchange privilege at any time on 60 days' notice to its shareholders of any
termination or material amendment.
    
 
   
  A prospectus of any of these mutual funds may be obtained from any broker,
dealer or financial intermediary or the Distributor. An investor considering an
exchange to one of such funds should refer to the prospectus for additional
information regarding such fund prior to investing.
    
 
   
  SYSTEMATIC WITHDRAWAL PLAN. Any investor whose shares in a single account
total $10,000 or more at the offering price next computed after receipt of
instructions may establish a monthly, quarterly, semi-annual or annual
withdrawal plan. Any investor whose shares in a single account total $5,000 or
more at the offering price next computed after receipt of instructions may
establish a quarterly, semi-annual or annual withdrawal plan. This plan provides
for the orderly use of the
    
 
                                       38
<PAGE>   55
 
entire account, not only the income but also the capital, if necessary. Each
withdrawal constitutes a redemption of shares on which taxable gain or loss will
be recognized. The plan holder may arrange for monthly, quarterly, semi-annual,
or annual checks in any amount not less than $25.
 
   
  Holders of Class B Shares and Class C Shares who establish a withdrawal plan
may redeem up to 12% annually of the shareholder's initial account balance
without incurring a contingent deferred sales charge. Initial account balance
means the amount of the shareholder's investment at the time the election to
participate in the plan is made.
    
 
  Under the plan, sufficient shares of the Fund are redeemed to provide the
amount of the periodic withdrawal payment. Dividends and capital gains
distributions on shares held under the plan are reinvested in additional shares
at the next determined net asset value. If periodic withdrawals continuously
exceed reinvested dividends and capital gains distributions, the shareholder's
original investment will be correspondingly reduced and ultimately exhausted.
Withdrawals made concurrently with purchases of additional shares ordinarily
will be disadvantageous to the shareholder because of the duplication of sales
charges. The Fund reserves the right to amend or terminate the systematic
withdrawal program on thirty days' notice to its shareholders.
 
  CHECK WRITING PRIVILEGE. Holders of Class A Shares of the Fund for which
certificates have not been issued and which are in a non-escrow status may
appoint ACCESS as agent by completing the Authorization for Redemption by Check
Form and the appropriate section of the application and returning the form and
the application to ACCESS. Once the form is properly completed, signed and
returned to the agent, a supply of checks drawn on State Street Bank and Trust
Company ("State Street Bank") will be sent to such shareholder. These checks may
be made payable by the holder of Class A Shares to the order of any person in
any amount of $100 or more.
 
  When a check is presented to State Street Bank for payment, full and
fractional Class A Shares required to cover the amount of the check are redeemed
from the shareholder's account by ACCESS at the next determined net asset value.
Check writing redemptions represent the sale of Class A Shares. Any gain or loss
realized on the sale of Class A Shares is a taxable event. See "Redemption of
Shares."
 
  Checks will not be honored for redemption of Class A Shares held less than 15
calendar days, unless such Class A Shares have been paid for by bank wire. Any
Class A Shares for which there are outstanding certificates may not be redeemed
by check. If the amount of the check is greater than the proceeds of all
uncertificated shares held in the shareholder's Class A Share account, the check
will be returned and the shareholder may be subject to additional charges.
Holders of Class A Shares may not liquidate the entire account by means of a
check. The check writing privilege may be terminated or suspended at any time by
the Fund or State Street Bank. Retirement plans and accounts that are subject to

eligible for the privilege. A "stop payment" system is not available on these
checks. See the Statement of Additional Information for further information
regarding the establishment of the privilege.
    
 
  AUTOMATED CLEARING HOUSE ("ACH") DEPOSITS. Holders of Class A Shares can use
ACH to have redemption proceeds deposited electronically into their bank
accounts. Redemptions transferred to a bank account via the ACH plan are
available to be credited to the account on the second business day following
normal payment. In order to utilize this option, the shareholder's bank must be
a member of Automated Clearing House. In addition, the shareholder must fill out
the appropriate section of the account application. The shareholder must also
include a voided check or deposit slip from the bank account into which
redemptions are to be deposited together with the completed application. Once
ACCESS has received the application and the voided check or deposit slip, such
shareholder's designated bank account, following any redemption, will be
credited with the proceeds of such redemption. Once enrolled in the ACH plan, a
shareholder may terminate participation at any time by writing ACCESS.
 
- ------------------------------------------------------------------------------
REDEMPTION OF SHARES
- ------------------------------------------------------------------------------
 
  Shareholders may redeem for cash some or all of their shares without charge by
the Fund (other than, with respect to CDSC Shares, the applicable contingent
deferred sales charge) at any time by sending a written request in proper form
directly to ACCESS, P.O. Box 418256, Kansas City, Missouri 64141-9256, by
placing the redemption request through an authorized dealer or by calling the
Fund.
 
  WRITTEN REDEMPTION REQUESTS. In the case of redemption requests sent directly
to ACCESS, the redemption request should indicate the number of shares to be
redeemed, the class designation of such shares, the account number and be signed
exactly as the shares are registered. Signatures must conform exactly to the
account registration. If the proceeds of the redemption would exceed $50,000, or
if the proceeds are not to be paid to the record owner at the record address, or
if the record address has changed within the previous 30 days, signature(s) must
be guaranteed by one of the following: a bank or trust company; a broker-dealer;
a credit union; a national securities exchange, registered securities
association or clearing agency; a savings and loan association; or a federal
savings bank. If certificates are held for the shares being redeemed, such
certificates must be endorsed for transfer or accompanied by an endorsed stock
power and sent with the redemption request. In the event the redemption is
requested by a corporation, partnership, trust, fiduciary, executor or
administrator, and the name and title of the individual(s) authorizing such
redemption is not shown in the account registration, a copy of the corporate
resolution or other legal documentation appointing the authorized signer and
certified within the prior 60 days must accompany the redemption request. The
redemption price is the net asset value per share next determined after the
request is received by ACCESS in proper form. Payment for
 
                                       40
<PAGE>   57
 
shares redeemed (less any sales charge, if applicable) will ordinarily be made
by check mailed within three business days after acceptance by ACCESS of the
request and any other necessary documents in proper order. Such payments may be
postponed or the right of redemption suspended as provided by the rules of the
SEC. If the shares to be redeemed have been recently purchased by check, ACCESS
may delay mailing a redemption check until it confirms that the purchase check
has cleared, usually a period of up to 15 days. Any gain or loss realized on the
redemption of shares is a taxable event.
 
  DEALER REDEMPTION REQUESTS. Shareholders may sell shares through their
securities dealer, who will telephone the request to the Distributor. Orders
received from dealers must be at least $500 unless transmitted via the FUNDSERV
network. The redemption price for such shares is the net asset value next
calculated after an order is received by a dealer provided such order is
transmitted to the Distributor prior to the Distributor's close of business on
such day. It is the responsibility of dealers to transmit redemption requests
received by them to the Distributor so they will be received prior to such time.
Any change in the redemption price due to failure of the Distributor to receive
a sell order prior to such time must be settled between the shareholder and
dealer. Shareholders must submit a written redemption request in proper form (as
described above under "Written Redemption Requests") to the dealer within three
business days after calling the dealer with the sell order. Payment for shares
redeemed (less any sales charge, if applicable) will ordinarily be made by check
mailed within three business days to the dealer.
 
   
  TELEPHONE REDEMPTION REQUESTS. The Fund permits redemption of shares by
telephone and for redemption proceeds to be sent to the address of record for
the account or to the bank account of record as described below. To establish
such privilege, a shareholder must complete the appropriate section of the
application accompanying this Prospectus or call the Fund at (800) 421-5666
((800) 421-2833 for the hearing impaired) to request that a copy of the
Telephone Redemption Authorization form be sent to them for completion. To
redeem shares, contact the telephone transaction line at (800) 421-5684. VKAC
and the Fund employ procedures considered by them to be reasonable to confirm
that instructions communicated by telephone are genuine. Such procedures include
requiring certain personal identification information prior to acting upon
telephone instructions, tape recording telephone communications, and providing
written confirmation of instructions communicated by telephone. If reasonable
procedures are employed, a shareholder agrees that neither VKAC nor the Fund
will be liable for following instructions which it reasonably believes to be
genuine. VKAC and the Fund may be liable for any losses due to unauthorized or
fraudulent instructions if reasonable procedures are not followed. Telephone
redemptions may not be available if the shareholder cannot reach ACCESS by
telephone, whether because all telephone lines are busy or for any other reason;
in such case, a shareholder would have to use the Fund's other redemption
procedures previously described. Requests received by ACCESS prior to 4:00 p.m.,
New York time, on a regular business day will be processed at the net asset
value per share determined that day. These privileges are
    
 
                                       41
<PAGE>   58
 
available for all accounts other than retirement accounts. The telephone
redemption privilege is not available for shares represented by certificates. If
the shares to be redeemed have been recently purchased by check, ACCESS may
delay mailing a redemption check or wiring redemption proceeds until it confirms
that the purchase check has cleared, usually a period of up to 15 days. If an
account has multiple owners, ACCESS may rely on the instructions of any one
owner.
 
  For redemptions authorized by telephone, amounts of $50,000 or less may be
redeemed daily if the proceeds are to be paid by check sent to the shareholders'
address of record and amounts of at least $1,000 and up to $1 million may be
redeemed daily if the proceeds are to be paid by wire sent to the shareholder's
bank account of record. The proceeds must be payable to the shareholder(s) of
record. Proceeds from redemptions to be paid by check will ordinarily be mailed
within three business days to the shareholder's address of record. Proceeds from
redemptions to be paid by wire will ordinarily be wired on the next business day
to the shareholder's bank account of record. This privilege is not available if
the address of record has been changed within 30 days prior to a telephone
redemption request. The Fund reserves the right at any time to terminate, limit
or otherwise modify this telephone redemption privilege.
 
   
  REDEMPTION UPON DISABILITY. The Fund will waive the CDSC on redemptions
following the disability of holders of Class B Shares and Class C Shares. An
individual will be considered disabled for this purpose if he or she meets the
definition thereof in Section 72(m)(7) of the Code, which in pertinent part
defines a person as disabled if such person "is unable to engage in any
substantial gainful activity by reason of any medically determinable physical or
mental impairment which can be expected to result in death or to be of
long-continued and indefinite duration." While the Fund does not specifically
adopt the balance of the Code's definition which pertains to furnishing the
Secretary of Treasury with such proof as he or she may require, the Distributor
will require satisfactory proof of disability before it determines to waive the
CDSC on Class B Shares and Class C Shares.
    
 
   
  In cases of disability, the CDSCs on Class B Shares and Class C Shares will be
waived where the disabled person is either an individual shareholder or owns the
shares as a joint tenant with right of survivorship or is the beneficial owner
of a custodial or fiduciary account, and where the redemption is made within one
year of the initial determination of disability. This waiver of the CDSC on
Class B Shares and Class C Shares applies to a total or partial redemption, but
only to redemptions of shares held at the time of the initial determination of
disability.
    
 
   
  GENERAL REDEMPTION INFORMATION. The Fund may redeem any shareholder account
with a net asset value on the date of the notice of redemption less than the
minimum investment as specified by the Trustees. At least 60 days advance
written notice of any such involuntary redemption is required and the
shareholder is given an opportunity to purchase the required value of additional
shares at the next determined net asset value without sales charge. Any
applicable CDSC will be deducted from the proceeds of this redemption. Any
involuntary redemption may
    
 
                                       42
<PAGE>   59
 
only occur if the shareholder account is less than the minimum investment due to
shareholder redemptions.
 
   
  REINSTATEMENT PRIVILEGE. Holders of Class A Shares or Class B Shares who have
redeemed shares of the Fund may reinstate any portion or all of the net proceeds
of such redemption in Class A Shares of the Fund. Holders of Class C Shares who
have redeemed shares of the Fund may reinstate any portion or all of the net
proceeds of such redemption in Class C Shares of the Fund with credit given for
any CDSC paid upon such redemption. Such reinstatement is made at the net asset
value (without sales charge except as described under "Shareholder Services --
Exchange Privilege") next determined after the order is received, which must be
within 180 days after the date of the redemption. See "Purchase of Shares --
Waiver of Contingent Deferred Sales Charge." Reinstatement at net asset value is
also offered to participants in those eligible retirement plans held or
administered by Van Kampen American Capital Trust Company for repayment of
principal (and interest) on their borrowings on such plans.
    
 
- ------------------------------------------------------------------------------
   
DISTRIBUTION AND SERVICE PLANS
    
- ------------------------------------------------------------------------------
 
  The Fund has adopted a distribution plan (the "Distribution Plan") with
respect to each class of its shares pursuant to Rule 12b-1 under the 1940 Act.
The Fund also has adopted a service plan (the "Service Plan") with respect to
each class of its shares. The Distribution Plan and the Service Plan provide
that the Fund may spend a portion of the Fund's average daily net assets
attributable to each class of shares in connection with distribution of the
respective class of shares and in connection with the provision of ongoing
services to shareholders of each class. The Distribution Plan and the Service
Plan are being implemented through an agreement with the Distributor and
sub-agreements between the Distributor and brokers, dealers or financial
intermediaries (collectively, "Selling Agreements") that may provide for their
customers or clients certain services or assistance.
 
   
  CLASS A SHARES. The Fund may spend an aggregate amount up to 0.25% per year of
the average daily net assets attributable to the Class A Shares of the Fund
pursuant to the Distribution Plan and Service Plan. From such amount, the Fund
may spend up to 0.25% per year of the Fund's average daily net assets
attributable to the Class A Shares pursuant to the Service Plan in connection
with the ongoing provision of services to holders of such shares by the
Distributor and by brokers, dealers or financial intermediaries and in
connection with the maintenance of such shareholders' accounts. The Fund pays
the Distributor the lesser of the balance of the 0.25% not paid to such brokers,
dealers or financial intermediaries or the amount of the Distributor's actual
distribution-related expense.
    
 
   
  CLASS B SHARES. The Fund may spend up to 0.75% per year of the average daily
net assets attributable to the Class B Shares of the Fund pursuant to the
Distribution Plan. In addition, the Fund may spend up to 0.25% per year of the
Fund's average daily net assets attributable to the Class B Shares pursuant to
the
    
 
                                       43
<PAGE>   60
 
Service Plan in connection with the ongoing provision of services to holders of
such shares by the Distributor and by brokers, dealers or financial
intermediaries and in connection with the maintenance of such shareholders'
accounts.
 
   
  CLASS C SHARES. The Fund may spend up to 0.75% per year of the average daily
net assets attributable to the Class C Shares of the Fund pursuant to the
Distribution Plan. From such amount, the Fund, or the Distributor as agent for
the Fund, pays brokers, dealers or financial intermediaries in connection with
the distribution of the Class C Shares up to 0.75% of the Fund's average daily
net assets attributable to Class C Shares maintained in the Fund more than one
year by such broker's, dealer's or financial intermediary's customers. The Fund
pays the Distributor the lesser of the balance of 0.75% not paid to such
brokers, dealers or financial intermediaries or the amount of the Distributor's
actual distribution related expense attributable to the Class C Shares. In
addition, the Fund may spend up to 0.25% per year of the Fund's average daily
net assets attributable to the Class C Shares pursuant to the Service Plan in
connection with the ongoing provision of services to holders of such shares by
the Distributor and by brokers, dealers or financial intermediaries and in
connection with the maintenance of such shareholders' accounts.
    
 
   
  OTHER INFORMATION. Amounts payable to the Distributor with respect to the
Class A Shares under the Distribution Plan in a given year may not fully
reimburse the Distributor for its actual distribution-related expenses during
such year. In such event, with respect to the Class A Shares, there is no
carryover of such reimbursement obligations to succeeding years.
    
 
   
  The Distributor's actual expenses with respect to a class of CDSC Shares (for
purposes of this section, excluding any Class A Shares that may be subject to a
CDSC) for any given year may exceed the amounts payable to the Distributor with
respect to such class of CDSC Shares under the Distribution Plan, the Service
Plan and payments received pursuant to the CDSC. In such event, with respect to
any such class of CDSC Shares, any unreimbursed expenses will be carried forward
and paid by the Fund (up to the amount of the actual expenses incurred) in
future years so long as such Distribution Plan is in effect. Except as mandated
by applicable law, the Fund does not impose any limit with respect to the number
of years into the future that such unreimbursed expenses may be carried forward
(on a Fund level basis). Because such expenses are accounted on a Fund level
basis, in periods of extreme net asset value fluctuation such amounts with
respect to a particular CDSC Share may be greater or less than the amount of the
initial commission (including carrying cost) paid by the Distributor with
respect to such CDSC Share. In such circumstances, a shareholder of such CDSC
Share may be deemed to incur expenses attributable to other shareholders of such
class. As of December 31, 1996, there were $6,391,172 and $112,259 of
unreimbursed distribution expenses with respect to Class B Shares and Class C
Shares, respectively, representing 3.68% and 0.60% of the Fund's net assets
attributable to Class B Shares and Class C Shares, respectively. If the
Distribution Plan was terminated or not continued, the Fund
    
 
                                       44
<PAGE>   61
 
   
would not be contractually obligated to pay the Distributor for any expenses not
previously reimbursed by the Fund or recovered through CDSCs.
    
 
   
  Because the Fund is a series of the Trust, amounts paid to the Distributor as
reimbursement for expenses of one series of the Trust may indirectly benefit the
other funds which are series of the Trust. The Distributor will endeavor to
allocate such expenses among such funds in an equitable manner. The Distributor
will not use the proceeds from the CDSC applicable to a particular class of
shares to defray distribution related expenses attributable to any other class
of shares. Various federal and state laws prohibit national banks and some
state-chartered commercial banks from underwriting or dealing in the Fund's
shares. In addition, state securities laws on this issue may differ from the
interpretations of federal law, and banks and financial institutions may be
required to register as dealers pursuant to state law. In the unlikely event
that a court were to find that these laws prevent such banks from providing such
services described above, the Fund would seek alternate providers and expects
that shareholders would not experience any disadvantage.
    
 
- ------------------------------------------------------------------------------
DISTRIBUTIONS FROM THE FUND
- ------------------------------------------------------------------------------
 
  The Fund's policy is to declare daily and pay monthly distributions of all or
substantially all net investment income of the Fund. Net investment income
consists of all or a portion of the interest income, dividends, other ordinary
income earned by the Fund on its portfolio assets, less all expenses of the
Fund. Expenses of the Fund are accrued each day. Net realized long- and
short-term capital gains, if any, are expected to be distributed, to the extent
permitted by applicable law, to shareholders at least annually. Distributions
cannot be assured, and the amount of each monthly distribution may vary.
 
  Distributions with respect to each class of shares will be calculated in the
same manner on the same day and will be in the same amount, except that the
different distribution and service fees and any incremental administrative
expenses relating to each class of shares will be borne exclusively by the
respective class and may cause the distributions relating to the different
classes of shares to differ. Generally, distributions with respect to a class of
shares subject to a higher distribution fee, service fee, or, where applicable,
the conversion feature will be lower than distributions with respect to a class
of shares subject to a lower distribution fee, service fee, or not subject to
the conversion feature.
 
   
  Investors will be entitled to begin receiving dividends on their shares on the
business day after ACCESS receives payments for such shares. However, shares
become entitled to dividends on the day ACCESS receives payment for the shares
either through a fed wire or NSCC settlement. Shares remain entitled to
dividends through the day such shares are processed for payment on redemption.
    
 
  Distribution checks may be sent to parties other than the shareholder in whose
name the account is registered. Persons wishing to utilize this service should
complete the appropriate section of the account application accompanying this
 
                                       45
<PAGE>   62
 
Prospectus or available from Van Kampen American Capital Funds, c/o ACCESS P.O.
Box 418256, Kansas City, MO 64141-9256. After ACCESS receives this completed
form, distribution checks will be sent to the bank or other person so designated
by such shareholder.
 
   
  PURCHASE OF ADDITIONAL SHARES WITH DISTRIBUTIONS.  The Fund will automatically
credit monthly distributions and any annual net long-term capital gain
distributions to a shareholder's account in additional shares of the Fund valued
at net asset value, without a sales charge. Unless a shareholder instructs
otherwise the reinvestment plan is automatic. This instruction may be made by
telephone by calling (800) 421-5666 ((800) 421-2833 for the hearing impaired) or
in writing to ACCESS. See "Shareholder Services -- Reinvestment Plan."
    
 
   
- ------------------------------------------------------------------------------
    
TAX STATUS
- ------------------------------------------------------------------------------
 
   
  FEDERAL INCOME TAXATION.  The Fund has qualified and intends to continue to
qualify each year and to elect to be treated as a regulated investment company
under Subchapter M of the Code. To qualify as a regulated investment company,
the Fund must comply with certain requirements of the Code relating to, among
other things, the source of its income and diversification of its assets.
    
 
   
  If the Fund so qualifies and distributes each year to its shareholders at
least 90% of its net investment income (including tax-exempt interest, taxable
income and net short-term capital gain, but not net capital gains, which are the
excess of net long-term capital gains over net short-term capital losses), it
will not be required to pay federal income taxes on any income distributed to
shareholders. The Fund intends to distribute at least the minimum amount of net
investment income necessary to satisfy the 90% distribution requirement. The
Fund will not be subject to federal income tax on any net capital gains
distributed to shareholders.
    
 
   
  In order to avoid a 4% excise tax, the Fund will be required to distribute, by
December 31 of each year, at least 98% of its ordinary income (not including
tax-exempt income) for such year and at least 98% of its capital gain net income
(the latter of which generally is computed on the basis of the one-year period
ending on October 31 of such year), plus any amounts that were not distributed
in previous taxable years. For purposes of the excise tax, any ordinary income
or capital gain net income retained by, and subject to federal income tax in the
hands of, the Fund will be treated as having been distributed.
    
 
   
  If the Fund failed to qualify as a regulated investment company or failed to
satisfy the 90% distribution requirement in any taxable year, the Fund would be
taxed as an ordinary corporation on its taxable income (even if such income were
distributed to its shareholders) and all distributions out of earnings and
profits would be taxed to shareholders as ordinary income. To qualify again as a
regulated investment company in a subsequent year, the Fund may be required to
pay an interest charge on 50% of its earnings and profits attributable to
non-regulated
    
 
                                       46
<PAGE>   63
 
   
investment company years and would be required to distribute such earnings and
profits to shareholders (less any interest charge). In addition, if the Fund
failed to qualify as a regulated investment company for its first taxable year
or, if immediately after qualifying as a regulated investment company for any
taxable year, it failed to qualify for a period greater than one taxable year,
the Fund would be required to recognize any net built-in gains (the excess of
aggregate gains, including items of income, over aggregate losses that would
have been realized if it had been liquidated) in order to qualify as a regulated
investment company in a subsequent year.
    
 
   
  Some of the Fund's investment practices are subject to special provisions of
the Code that, among other things, may defer the use of certain losses of the
Fund and affect the holding period of the securities held by the Fund and the
character of the gains or losses realized by the Fund. These provisions may also
require the Fund to mark-to-market some of the positions in its portfolio (i.e.,
treat them as if they were sold for fair market value at the end of the
tax-year), which may cause the Fund to recognize income without receiving cash
with which to make distributions in amounts necessary to satisfy the 90%
distribution requirement and the distribution requirements for avoiding income
and excise taxes. The Fund will monitor its transactions and may make certain
tax elections in order to mitigate the effect of these rules and prevent
disqualification of the Fund as a regulated investment company.
    
 
   
  The Fund's ability to dispose of portfolio securities may be limited by the
requirement for qualification as a regulated investment company that less than
30% of the Fund's annual gross income be derived from the disposition of
securities held for less than three months.
    
 
   
  Investments of the Fund in securities issued at a discount or providing for
deferred interest or payment of interest in kind are subject to special tax
rules that will affect the amount, timing and character of distributions to
shareholders. For example, with respect to securities issued at a discount, the
Fund will be required to accrue as income each year a portion of the discount
and to distribute such income each year in order to maintain its qualification
as a regulated investment company and to avoid income and excise taxes. In order
to generate sufficient cash to make distributions necessary to satisfy the 90%
distribution requirement and to avoid income and excise taxes, the Fund may have
to dispose of securities that it would otherwise have continued to hold. A
portion of the discount relating to certain stripped tax-exempt obligations may
constitute taxable income when distributed to shareholders.
    
 
   
  DISTRIBUTIONS.  The Fund intends to invest in sufficient tax-exempt municipal
securities to permit payment of "exempt-interest dividends" (as defined in the
Code). Dividends paid by the Fund from the net tax-exempt interest earned from
municipal securities qualify as exempt-interest dividends if, at the close of
each quarter of its taxable year, at least 50% of the value of the total assets
of the Fund consists of municipal securities.
    
 
                                       47
<PAGE>   64
 
   
  The Tax Reform Act of 1986 (the "Tax Reform Act") may have an adverse impact
upon the Fund and its shareholders. The Tax Reform Act imposed new limitations
on the use and investment of the proceeds of state and local government bonds
and other funds, which limitations must be satisfied in order to maintain the
exclusion from gross income for interest on such bonds. The provisions of the
Tax Reform Act generally apply to bonds issued after August 15, 1986. In light
of these requirements, bond counsel qualify their opinions as to the federal tax
status of bonds issued after August 15, 1986 by making them contingent on the
issuer's future compliance with these limitations. Any failure on the part of an
issuer to comply could cause the interest on its bonds to become taxable to
investors retroactive to the date the bonds were issued.
    
 
   
  Except as provided below, exempt-interest dividends paid to shareholders
generally are not includable in the shareholders' gross income for federal
income tax purposes. The percentage of the total dividends paid by the Fund
during any taxable year that qualify as exempt-interest dividends will be the
same for all shareholders of the Fund receiving dividends during such year.
    
 
   
  The Tax Reform Act also makes interest on certain "private-activity bonds" an
item of tax preference subject to the alternative minimum tax on individuals and
corporations. The Fund invests a portion of its assets in municipal securities
subject to this provision so that a portion of its exempt-interest dividends is
an item of tax preference to the extent such dividends represent interest
received from these private-activity bonds. Accordingly, investment in the Fund
could cause shareholders to be subject to (or result in an increased liability
under) the alternative minimum tax. The Tax Reform Act also imposed per capita
volume limitations on certain private-activity bonds which could limit the
amount of such bonds available for investment by the Fund.
    
 
   
  Exempt-interest dividends are included in determining what portion, if any, of
a person's social security and railroad retirement benefits will be includable
in gross income subject to federal income tax.
    
 
   
  Although exempt-interest dividends generally may be treated by Fund
shareholders as items of interest excluded from their gross income, each
shareholder is advised to consult his tax adviser with respect to whether
exempt-interest dividends retain this exclusion if the purchaser would be
treated as a "substantial user" (or a "related person" of a substantial user) of
the facilities financed with respect to any of the tax-exempt obligations held
by the Fund, or by the Trust if it is required to qualify as a regulated
investment company as described below. "Substantial user" is defined under U.S.
Treasury Regulations to include a non-exempt person who regularly uses in his
trade or business a part of any facilities financed with the tax-exempt
obligations and whose gross revenues derived from such facilities exceed five
percent of the total revenues derived from the facilities by all users, or who
occupies more than 5% of the useable area of the facilities or for whom the
facilities or a part thereof were specifically constructed, reconstructed or
acquired. Examples
    
 
                                       48
<PAGE>   65
 
   
of "related persons" include certain related natural persons, affiliated
corporations, a partnership and its partners and an S corporation and its
shareholders.
    
 
   
  The Omnibus Budget Reconciliation Act of 1993 included certain provisions that
requires gains on dispositions of tax-exempt securities purchased at a market
discount be treated as ordinary income to the extent of the accrued market
discount, if the securities are acquired after April 30, 1993. Such securities
were exempt from the market discount rules under prior law. Interest on
indebtedness incurred or continued by a shareholder to purchase or carry shares
of the Fund is not deductible for federal income tax purposes if the Fund
distributes exempt-interest dividends during the shareholder's taxable year. If
a shareholder receives an exempt-interest dividend with respect to any shares
and such shares are held for six months or less, any short-term capital loss on
the sale or exchange of the shares will be disallowed to the extent of the
amount of such exempt-interest dividend.
    
 
   
  While the Fund expects that a major portion of its net investment income will
constitute tax-exempt interest, a significant portion may consist of investment
company taxable income. Distributions of the Fund's net investment company
taxable income are taxable to shareholders as ordinary income to the extent of
the Fund's earnings and profits, whether paid in cash or reinvested in
additional shares. Distributions of the Fund's net capital gains ("capital gains
dividends"), if any, are taxable to shareholders as long-term capital gains
regardless of the length of time shares of the Fund have been held by such
shareholders. Interest on indebtedness which is incurred to purchase or carry
shares of a mutual fund which distributes exempt-interest dividends during the
year is not deductible for federal income tax purposes. Distributions in excess
of the Fund's earnings and profits will first reduce the adjusted tax basis of a
holder's shares and, after such adjusted tax basis is reduced to zero, will
constitute capital gains to such holder (assuming such shares are held as a
capital asset). Tax-exempt shareholders not subject to federal income tax on
their income generally will not be taxed on distributions from the Fund.
    
 
   
  Shareholders receiving distributions in the form of additional shares issued
by the Fund will be treated for federal income tax purposes as receiving a
distribution in an amount equal to the fair market value of the shares received,
determined as of the distribution date. The basis of such shares will equal the
fair market value on the distribution date.
    
 
   
  The Fund will inform shareholders of the source and tax status of all
distributions promptly after the close of each calendar year. The aggregate
amount of dividends so designated cannot exceed, however, the amount of interest
exempt from tax under Section 103 of the Code received by the Fund during the
year over any amounts disallowed as deductions under Sections 265 and 171(a)(2)
of the Code. Since the percentage of dividends which are "exempt-interest"
dividends is determined on an average annual method for the fiscal year, the
percentage of income designated as tax-exempt for any particular dividend may be
substantially different from the percentage of the Fund's income that was tax
exempt during the period
    
 
                                       49

covered by the dividend, Fund distributions generally will not qualify for the
dividends received deduction for corporations.
    
 
   
  Although dividends generally will be treated as distributed when paid,
dividends declared in October, November or December, payable to shareholders of
record on a specified date in such month and paid during January of the
following year will be treated as having been distributed by the Fund and
received by the shareholders on the December 31 prior to the date of payment. In
addition, certain other distributions made after the close of a taxable year of
the Fund may be "spilled back" and treated as paid by the Fund (except for
purposes of the 4% excise tax) during such taxable year. In such case,
shareholders will be treated as having received such dividends in the taxable
year in which the distribution was actually made.
    
 
   
  The Fund is required, in certain circumstances, to withhold 31% of dividends
and certain other payments, including redemptions, paid to shareholders who do
not furnish to the Fund their correct taxpayer identification number (in the
case of individuals, their social security number) and certain required
certifications or who are otherwise subject to backup withholding.
    
 
   
  SALE OF SHARES.  The sale of shares (including transfers in connection with a
redemption or repurchase of shares) will be a taxable transaction for federal
income tax purposes. Selling shareholders will generally recognize gain or loss
in an amount equal to the difference between their adjusted tax basis in the
shares and the amount received. If such shares are held as a capital asset, the
gain or loss will be a capital gain or loss and will be long-term if such shares
have been held for more than one year. Any loss realized upon a taxable
disposition of shares held for six months or less will be treated as a long-term
capital loss to the extent of any capital gains dividends received with respect
to such shares. For purposes of determining whether shares have been held for
six months or less, the holding period is suspended for any periods during which
the shareholder's risk of loss is diminished as a result of holding one or more
other positions in substantially similar or related property or through certain
options or short sales.
    
 
   
  STATE AND LOCAL TAXES.  The exemption of interest income for federal income
tax purposes may not result in similar exemptions under the laws of a particular
state or local taxing authority. Income distributions may be taxable to
shareholders under state or local law as dividend income even though a portion
of such distributions may be derived from interest on tax-exempt obligations
which, if realized directly, would be exempt from such income taxes. It is
recommended that investors consult their tax advisers for information in this
regard. The Fund will report annually to its shareholders the percentage and
source, on a state-by-state basis, of interest income earned on municipal
securities received by the Fund during the preceding calendar year. Dividends
and distributions paid by the Fund from sources other than tax-exempt interest
are generally subject to taxation at the state and local levels.

  GENERAL.  The federal, state and local income tax discussion set forth above
is for general information only. Prospective investors should consult their
advisors regarding the specific federal tax consequences of holding and
disposing of shares, as well as the effects of state, local and foreign tax law
and any proposed tax law changes.

FUND PERFORMANCE
- ------------------------------------------------------------------------------
 
   
  From time to time advertisements and other sales materials for the Fund may
include information concerning the historical performance of the Fund. Any such
information will include the average total return of the Fund calculated on a
compounded basis for specified periods of time. Such advertisements and sales
material may also include a yield quotation as of a current period. In each
case, such total return and yield information, if any, will be calculated
pursuant to rules established by the SEC and will be computed separately for
each class of the Fund's shares. In lieu of or in addition to total return and
yield calculations, such information may include performance rankings and
similar information from independent organizations such as Lipper Analytical
Services, Inc.
    
 
  The Fund's yield quotation is determined for each class of the Fund's shares
on a monthly basis with respect to the immediately preceding 30 day period.
Yield is computed by dividing the Fund's net investment income per share earned
during such 30 day period by the Fund's maximum offering price per share on the
last day of such period. Net investment income per share for a class of shares
is determined by taking the interest earned by the Fund during the period and
allocable to the class of shares, subtracting the expenses (net of any
reimbursement) accrued for the period and allocable to the class of shares, and
dividing the result by the product of (a) the average daily number of such class
of the Fund's shares outstanding during the period that were entitled to receive
dividends and (b) the Fund's maximum offering price per share on the last day of
the period. The yield calculation formula assumes net investment income is
earned and reinvested at a constant rate and annualized at the end of a six
month period.
 
  Tax-equivalent yield demonstrates the taxable yield required to produce an
after-tax yield equivalent to that of the Fund's yield. The Fund's
tax-equivalent yield quotation for a 30 day period as described above is
computed for each class of the Fund's shares by dividing that portion of the
yield of the Fund (as computed above) which is tax-exempt by a percentage equal
to 100% minus a stated percentage income tax rate and adding the result to that
portion of the Fund's yield, if any, that is not tax-exempt.
 
  The Fund calculates average compounded total return for each class of the
Fund's shares by determining the redemption value at the end of specified
periods (after adding back all dividends and other distributions made during the
period) of a $1,000 investment in a class of shares of the Fund (less the
maximum sales charge) at the beginning of the period, annualizing the increase
or decrease over the
 
                                       51
<PAGE>   68
 
specified period with respect to such initial investment and expressing the
result as a percentage.
 
  Total return figures utilized by the Fund are based on historical performance
and are not intended to indicate future performance. Total return and net asset
value per share can be expected to fluctuate over time, and accordingly upon
redemption a shareholder's shares may be worth more or less than their original
cost.
 
  The Fund may, in supplemental sales literature, advertise non-standardized
total return figures representing the cumulative, non-annualized total return of
the Fund from a given date to a subsequent given date. Cumulative
non-standardized total return is calculated by measuring the value of an initial
investment in the Fund at a given time, deducting the maximum sales charge of
4.75%, determining the value of all subsequent reinvested distributions, and
dividing the net change in the value of the investment as of the end of the
period by the amount of the initial investment and expressing the result as a
percentage.
 
   
  From time to time the Fund may include in its supplemental sales literature
and shareholder reports a quotation of the current "distribution rate" for the
Fund. Distribution rate is a measure of the level of income and short-term
capital gain dividends, if any, distributed for a specified period. Distribution
rate is determined by annualizing the distributions per share for a stated
period and dividing the result by the public offering price for the same period.
It differs from yield, which is a measure of the income actually earned by the
Fund's investments, and from total return, which is a measure of the income
actually earned by, plus the effect of any realized and unrealized appreciation
or depreciation of such investments during a stated period. Distribution rate
is, therefore, not intended to be a complete measure of the Fund's performance.
Distribution rate may sometimes be greater than yield since, for instance, it
may not include the effect of amortization of bond premiums, and may include
non-recurring short-term capital gains and premiums from futures transactions
engaged in by the Fund. Distribution rates will be calculated separately for
each class of the Fund's shares.
    
 
  From time to time the Fund may compare its performance to certain securities
and unmanaged indices which may have different risk/reward characteristics than
the Fund. Such characteristics may include, but are not limited to, tax
features, guarantees, insurance and the fluctuation of principal and/or return.
In addition, from time to time, the Fund may utilize sales literature that
includes hypotheticals.
 
   
  Further information about the Fund's performance is contained in the Fund's
Annual Report and the Fund's Statement of Additional Information, each of which
can be obtained without charge by calling (800) 421-5666 ((800) 421-2833 for the

DESCRIPTION OF SHARES OF THE FUND
- ------------------------------------------------------------------------------
 
  The Fund is a separate series of the Van Kampen American Capital Tax Free
Trust, a Delaware business trust organized as of May 10, 1995 (the "Trust"). The
 
                                       52
<PAGE>   69
 
Fund was originally organized in 1985 under the name Van Kampen Merritt Tax Free
High Income Fund as a sub-trust of Van Kampen Merritt Tax Free Fund, a
Massachusetts business trust. The Fund was reorganized as a series of the Trust
on July 31, 1995. Shares of the Trust entitle their holders to one vote per
share; however, separate votes are taken by each series on matters affecting an
individual series.
 
   
  The authorized capitalization of the Fund consists of an unlimited number of
shares of beneficial interest, $0.01 par value, divided into three classes,
designated Class A Shares, Class B Shares and Class C Shares. Each class of
shares represent an interest in the same assets of the Fund and are identical in
all respects except that each class bears certain distribution expenses and has
exclusive voting rights with respect to its distribution fee. See "Distribution
and Service Plans."
    
 
   
  The Fund is permitted to issue an unlimited number of classes of shares. Each
class of share is equal as to earnings, assets and voting privileges, except as
noted above, and each class bears the expenses related to the distribution of
its shares. There are no conversion, preemptive or other subscription rights,
except with respect to the conversion of Class B Shares and certain Class C
Shares into Class A Shares as described above. In the event of liquidation, each
of the shares of the Fund is entitled to its portion of all of the Fund's net
assets after all debt and expenses of the Fund have been paid. Since Class B
Shares and Class C Shares pay higher distribution expenses, the liquidation
proceeds to holders of Class B Shares and Class C Shares are likely to be lower
than to holders of Class A Shares.
    
 
  The Trust does not contemplate holding regular meetings of shareholders to
elect Trustees or otherwise. However, the holders of 10% or more of the
outstanding shares may by written request require a meeting to consider the
removal of Trustees by a vote of two-thirds of the shares then outstanding cast
in person or by proxy at such meeting. The Trust will assist such holders in
communicating with other shareholders of the Fund to the extent required by the
1940 Act. More detailed information concerning the Trust is set forth in the
Statement of Additional Information.

                  DESCRIPTION OF MUNICIPAL SECURITIES RATINGS
 
  STANDARD & POOR'S RATINGS GROUP--A brief description of the applicable
Standard & Poor's Ratings Group (S&P) rating symbols and their meanings (as
published by S&P) follows:
 
    1.  DEBT
 
   
        A S&P corporate or municipal debt rating is a current assessment of the
    creditworthiness of an obligor with respect to a specific obligation. This
    assessment may take into consideration obligors such as guarantors,
    insurers, or lessees.
    
 
        The debt rating is not a recommendation to purchase, sell or hold a
    security, inasmuch as it does not comment as to market price or suitability
    for a particular investor.
 
        The ratings are based on current information furnished by the issuer or
    obtained by S&P from other sources it considers reliable. S&P 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 based on other circumstances.
 
         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;
 
         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.
 
<TABLE>
    <S>         <C>
    AAA         Debt rated 'AAA' has the highest rating assigned by S&P.
                Capacity to pay interest and repay principal is
                extremely strong.
 
    AA          Debt rated 'AA' has a very strong capacity to pay
                interest and repay principal and differs from the higher
                rated issues only in small degree.
 
    A           Debt rated 'A' has a strong capacity to pay interest and
                repay principal although it is somewhat more susceptible
                to the adverse effects of changes in circumstances and
                economic conditions than debt in higher rated
                categories.
</TABLE>
 
                                       55
<PAGE>   72
   
    BBB         Debt rated 'BBB' is regarded as having an adequate
                capacity to pay interest and repay principal. Whereas it
                normally exhibits adequate protection parameters,
                adverse economic conditions or changing circumstances
                are more likely to lead to a weakened capacity to pay
                interest and repay principal for debt in this category
                than in higher rated categories.
 
    BB          Debt rated 'BB', 'B', 'CCC', 'CC' and 'C' is regarded,
    B           on balance, as predominantly speculative with respect to
    CCC         capacity to pay interest and repay principal. 'BB'
    CC          indicates the least degree of speculation and 'C' the
    C           highest. While such debt will likely have some quality
                and protective characteristics, these are outweighed by
                large uncertainties or large exposures to adverse
                conditions.
 
    BB          Debt rated 'BB' has less near-term vulnerability to
                default than other speculative issues. However, it faces
                major ongoing uncertainties or exposure to adverse
                business, financial, or economic conditions which could
                lead to inadequate capacity to meet timely interest and
                principal payments. The 'BB' rating category is also
                used for debt subordinated to senior debt that is
                assigned an actual or implied 'BBB-' rating.
 
    B           Debt rated 'B' has a greater vulnerability to default
                but currently has the capacity to meet interest payments
                and principal repayments. Adverse business, financial,
                or economic conditions will likely impair capacity or
                willingness to pay interest and repay principal. The 'B'
                rating category is also used for debt subordinated to
                senior debt that is assigned an actual or implied 'BB'
                or 'BB-' rating.
 
    CCC         Debt rated 'CCC' has a currently identifiable
                vulnerability to default, and is dependent upon
                favorable business, financial, and economic conditions
                to meet timely payment of interest and repayment of
                principal. In the event of adverse business, financial,
                or economic conditions, it is not likely to have the
                capacity to pay interest and repay principal. The 'CCC'
                rating category is also used for debt subordinated to
                senior debt that is assigned an actual or implied 'B' or
                'B-' rating.
 
    CC          The rating 'CC' typically is applied to debt
                subordinated to senior debt that is assigned an actual
                or implied 'CCC' rating.
 
    C           The rating 'C' typically is applied to debt subordinated
                to senior debt which is assigned an actual or implied
                'CCC-' debt rating. The 'C' rating may be used to cover
                a situation where a bankruptcy petition has been filed,
                but debt service payments are continued.
    
 
                                       56
<PAGE>   73
    CI          The rating 'CI' is reserved for income bonds on which no
                interest is being paid.
 
    D           Debt rated 'D' is in payment default. The 'D' rating
                category is used when interest payments or principal
                payments are not made on the date due even if the
                applicable grace period has not expired, unless S&P
                believes that such payments will be made during such
                grace period. The 'D' rating also will be used upon the
                filing of a bankruptcy petition if debt service payments
                are jeopardized.
 
               PLUS (+) or MINUS (-): The ratings from 'AA' to 'CCC' may be
               modified by the addition of a plus or minus sign to show relative
               standing within the major categories.
 
    C          The letter 'c' indicates that the holder's option to
               tender the security for purchase may be canceled under
               certain prestated conditions enumerated in the tender
               option documents.
 
    L          The letter 'L' indicates that the rating pertains to the
               principal amount of these bonds to the extent that the
               underlying deposit collateral is federally insured and
               interest is adequately collateralized. In the case of
               certificates of deposit, the letter 'L' indicates that
               the deposit, combined with other deposits being held in
               the same right and capacity, will be honored for
               principal and accrued pre-default interest up to the
               federal insurance limits within 30 days after closing of
               the insured institution or, in the event that the
               deposit is assumed by a successor insured institution,
               upon maturity.
 
    P          The letter 'p' indicates that the rating is provisional.
               A provisional rating assumes the successful completion
               of the project being financed by the debt being rated
               and indicates that payment of debt service requirements
               is largely or entirely dependent upon the successful and
               timely completion of the project. This rating, however,
               while addressing credit quality subsequent to completion
               of the project, makes no comment on the likelihood of,
               or the risk of default upon failure of, such completion.
               The investor should exercise his own judgment with
               respect to such likelihood and risk.
 
               *Continuance of the rating is contingent upon S&P's
               receipt of an executed copy of the escrow agreement or
               closing documentation confirming investments and cash
               flows.
 
    NR         Indicates that no public rating has been requested, that
               there is insufficient information on which to base a
               rating, or that S&P does not rate a particular type of
               obligation as a matter of policy.
 
                                       57
<PAGE>   74
 
    DEBT OBLIGATIONS OF ISSUERS OUTSIDE THE UNITED STATES AND ITS TERRITORIES
    are rated on the same basis as domestic corporate and municipal issues. The
    ratings measure the creditworthiness of the obligor but do not take into
    account currency exchange and related uncertainties.
 
    BOND INVESTMENT QUALITY STANDARDS: Under present commercial bank regulations
    issued by the Comptroller of the Currency, bonds rated in the top four
    categories ('AAA', 'AA', 'A', 'BBB' commonly known as "investment grade"
    ratings) are generally regarded as eligible for bank investment. In
    addition, the laws of various states governing legal investments impose
    certain rating or other standards for obligations eligible for investment by
    savings banks, trust companies, insurance companies, and fiduciaries
    generally.
 
    2.  MUNICIPAL NOTES
 
         A S&P note rating reflects the liquidity factors and market access
         risks unique to notes. Notes maturing in 3 years or less will likely
         receive a note rating. Notes maturing beyond 3 years will most likely
         receive a long-term debt rating.
 
         The following criteria will be used in making that assessment:
 
        -- Amortization schedule (the larger the final maturity relative to
           other maturities, the more likely the issue be treated as a note).
 
        -- Source of payment (the more the issue depends on the market for its
           refinancing, the more likely it is to be treated as a note).
 
         The note rating symbols and definitions are as follows:
 
<TABLE>
    <S>         <C>
    SP-1        Strong capacity to pay principal and interest. Issues
                determined to possess very strong characteristics are a
                plus (+) designation.
 
    SP-2        Satisfactory capacity to pay principal and interest,
                with some vulnerability to adverse financial and
                economic changes over the term of the notes.
 
    SP-3        Speculative capacity to pay principal and interest.
</TABLE>
 
    3.  COMMERCIAL PAPER
 
        A S&P 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.
 
                                       58
<PAGE>   75
 
        Ratings are graded into several categories, ranging from 'A-1' for the
    highest quality obligations to 'D' for the lowest. These categories are as
    follows:
 
<TABLE>
    <S>         <C>
    A-1         This highest category indicates that the degree of
                safety regarding timely payment is strong. Those issues
                determined to possess extremely strong safety
                characteristics are denoted with a plus sign (+)
                designation.
 
    A-2         Capacity for timely payment on issues with this
                designation is satisfactory. However, the relative
                degree of safety is not as high as for issues designated
                'A-1'.
 
    A-3         Issues carrying this designation have adequate capacity
                for timely payment. They are, however, more vulnerable
                to the adverse effects of changes in circumstances than
                obligations carrying the higher designations.
 
    B           Issues rated 'B' are regarded as having only speculative
                capacity for timely payment.
 
    C           This rating is assigned to short-term debt obligations
                with a doubtful capacity for payment.
 
    D           Debt rated 'D' is in payment default. The 'D' rating
                category is used when interest payments or principal
                payments are not made on the date due, even if the
                applicable grace period has not expired, unless S&P
                believes that such payments will be made during such
                grace period.
 
    A commercial paper rating is not a recommendation to purchase or
    sell a security. The ratings are based on current information
    furnished to S&P by the issuer or obtained 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.
</TABLE>
 
    4.  TAX-EXEMPT DUAL RATINGS
 
        S&P assigns "dual" ratings to all debt issues that have a put option or
    demand feature as part of their structure.
 
        The first rating addresses the likelihood of repayment of principal and
    interest as due, and the second rating addresses only the demand feature.
    The long-term debt rating symbols are used for bonds to denote the long-term
    maturity and the commercial paper rating symbols for the put option (for
    example, 'AAA/A-1+'). With short-term demand debt, S&P's note rating symbols
    are used with the commercial paper rating symbols (for example, 'SP-
    1+/A-1+').

  MOODY'S INVESTORS SERVICE--A brief description of the applicable Moody's
Investors Service ("Moody's") rating symbols and their meanings (as published by
Moody's) follows:
 
    1.  LONG-TERM MUNICIPAL BONDS
 
<TABLE>
    <S>         <C>
    AAA         Bonds which are rated Aaa are judged to be of the best
                quality. They carry the smallest degree of investment
                risk and are generally referred to as "gilt edged."
                Interest payments are protected by a large or by an
                exceptionally stable margin and principal is secure.
                While the various protective elements are likely to
                change, such changes as can be visualized are most
                unlikely to impair the fundamentally strong position of
                such issues.
 
    AA          Bonds which are rated Aa are judged to be of high
                quality by all standards. Together with the Aaa group
                they comprise what are generally known as high grade
                bonds. They are rated lower than the best bonds because
                margins of protection may not be as large as in Aaa
                securities or fluctuation of protective elements may be
                of greater amplitude or there may be other elements
                present which make the long-term risk appear somewhat
                larger than the Aaa securities.
 
    A           Bonds which are rated A possess many favorable
                investment attributes and are to be considered as
                upper-medium-grade obligations. Factors giving security
                to principal and interest are considered adequate, but
                elements may be present which suggest a susceptibility
                to impairment some time in the future.
 
    BAA         Bonds which are rated Baa are considered as medium-grade
                obligations, (i.e., they are neither highly protected
                nor poorly secured). Interest payments and principal
                security appear adequate for the present but certain
                protective elements may be lacking or may be
                characteristically unreliable over any great length of
                time. Such bonds lack outstanding investment
                characteristics and in fact have speculative
                characteristics as well.
 
    BA          Bonds which are rated Ba are judged to have speculative
                elements; their future cannot be considered as
                well-assured. Often the protection of interest and
                principal payments may be very moderate, and thereby not
                well safeguarded during both good and bad times over the
                future. Uncertainty of position characterizes bonds in
                this class.
 
    B           Bonds which are rated B generally lack characteristics
                of the desirable investment. Assurance of interest and
                principal payments or of maintenance of other terms of
                the contract over any long period of time may be small.
</TABLE>
 
                                       60
<PAGE>   77
   
    CAA         Bonds which are rated Caa are of poor standing. Such
                issues may be in default or there may be present
                elements of danger with respect to principal or
                interest.
 
    CA          Bonds which are rated Ca represent obligations which are
                speculative in a high degree. Such issues are often in
                default or have other marked shortcomings.
 
    C           Bonds which are rated C are the lowest rated class of
                bonds, and issues so rated can be regarded as having
                extremely poor prospects of ever attaining any real
                investment standing.
 
    CON (..)    Bonds for which the security depends upon the completion
                of some act or the fulfillment of some condition are
                rated conditionally and designed with the prefix "Con"
                followed by the rating in parentheses. These are bonds
                secured by: (a) earnings of projects under construction,
                (b) earnings of projects unseasoned in operating
                experience, (c) rentals that begin when facilities are
                completed, or (d) payments to which some other limiting
                condition attaches. The parenthetical rating denotes the
                probable credit stature upon completion of construction
                or elimination of the basis of the condition.
 
    (P) (..)    When applied to forward delivery bonds, indicates that
                the rating is provisional pending the delivery of the
                bonds. The rating may be revised prior to delivery if
                changes occur in the legal documents or the underlying
                credit quality of the bonds.
 
    NOTE:       Moody's applies numerical modifiers, 1, 2 and 3 in each
                generic rating classification from AA to B. The modifier
                1 indicates that the company ranks in the higher end of
                its generic rating category; the modifier 2 indicates a
                mid-range ranking; and the modifier 3 indicates that the
                company ranks in the lower end of its generic rating
                category.
 
    
 
        ABSENCE OF RATING: Where no rating has been assigned or where a rating
    has been suspended or withdrawn, it may be for reasons unrelated to the
    quality of the issue.
 
        Should no rating be assigned, the reason may be one of the following:
 
             1. An application for rating was not received or accepted.
 
             2. The issue or issuer belongs to a group of securities or
                companies that are not rated as a matter of policy.
 
             3. There is a lack of essential data pertaining to the issue or
                issuer.
 
             4. The issue was privately placed, in which case the rating is not
                published in Moody's publications.
 
                                       61
<PAGE>   78
 
        Suspension or withdrawal may occur if new and material circumstances
    arise, the effects of which preclude satisfactory analysis; if there is no
    longer available reasonable up-to-date data to permit a judgment to be
    formed; if a bond is called for redemption; or for other reasons.
 
    2.  SHORT-TERM EXEMPT NOTES
 
        Moody's ratings for state and municipal short-term obligations will be
    designated Moody's Investment Grade or (MIG). Such ratings recognize the
    differences between short-term credit risk and long-term risk. Factors
    affecting the liquidity of the borrower and short-term cyclical elements are
    critical in short-term ratings, while other factors of major importance in
    bond risk, long-term secular trends for example, may be less important over
    the short run. A short-term rating may also be assigned on an issue having a
    demand feature-variable rate demand obligation. Such ratings will be
    designated as VMIG, SG or, if the demand feature is not rated, as NR.
 
        Moody's short-term ratings are designated Moody's Investment Grade as
    MIG 1 or VMIG 1 through MIG 4 or VMIG 4. As the name implies, when Moody's
    assigns a MIG or VMIG rating, all categories define an investment grade
    situation.
 
        MIG 1/VMIG 1. This designation denotes best quality. There is present
    strong protection by established cash flows, superior liquidity support or
    demonstrated broad-based access to the market for refinancing.
 
        MIG 2/VMIG 2. This designation denotes high quality. Margins of
    protection are ample although not so large as in the preceding group.
 
        MIG 3/VMIG 3. This designation denotes favorable quality. All security
    elements are accounted for but there is lacking the undeniable strength of
    the preceding grades. Liquidity and cash flow protection may be narrow and
    market access for refinancing is likely to be less well established.
 
        MIG 4/VMIG 4. This designation denotes adequate quality. Protection
    commonly regarded as required of an investment security is present and
    although not distinctly or predominantly speculative, there is specific
    risk.
 
        SG. This designation denotes speculative quality. Debt instruments in
    this category lack margins of protection.
 
    3.  TAX-EXEMPT COMMERCIAL PAPER
 
   
        Moody's short-term debt ratings are opinions of the ability of issuers
    to repay punctually promissory obligations not having an original maturity
    in excess of nine months. Moody's makes no representation that such
    obligations are exempt from registration under the Securities Act of 1933,
    nor does it represent that any specific note is a valid obligation of a
    rated issuer or issued in conformity with any applicable law.
    
 
                                       62
<PAGE>   79
 
        Moody's employs the following three designations, all judged to be
    investment grade, to indicate the relative repayment ability of rated
    issuers:
 
   
      Issuers rated Prime-1 (for related supporting institutions) have a
    superior capacity for repayment of short-term promissory obligations.
    Prime-1 repayment capacity will normally be evidenced by the following
    characteristics:
    
 
   
           - Leading market positions in well established industries.
    
 
   
           - High rates of return on funds employed.
    
 
   
           - Conservative capitalization structures with moderate reliance on
             debt and ample asset protection.
    
 
   
           - Broad margins in earning coverage of fixed financial charges and
             high internal cash generation.
    
 
   
           - Well established access to a range of financial markets and assured
             sources of alternate liquidity.
    
 
   
      Issuers rated Prime-2 (or related supporting institutions) have a strong
    capacity for repayment of short-term promissory obligations. This will
    normally be evidenced by many of the characteristics cited above but to a
    lesser degree. Earnings trends and coverage ratios, while sound, will be
    more subject to variation. Capitalization characteristics, while still
    appropriate, may be more affected by external conditions. Ample alternate
    liquidity is maintained.
    
 
   
      Issuers rated Prime-3 (or related supporting institutions) have an
    acceptable capacity for repayment of short-term promissory obligations. The
    effects of industry characteristics and market composition may be more
    pronounced. Variability in earnings and profitability may result in changes
    in the level of debt protection measurements and the requirement for
    relatively high financial leverage. Adequate alternate liquidity is
    maintained.
    
 
   
      Issuers rated Not Prime do not fall within any of the Prime rating
    
   
    categories.

- ------------------------------------------------------------------------------
 
THE FUNDS.  Van Kampen American Capital Insured Tax Free Income Fund (the
"Insured Fund") and Van Kampen American Capital California Insured Tax Free Fund
(the "California Insured Fund") are each separate diversified series of Van
Kampen American Capital Tax Free Trust, an open-end, diversified management
investment company organized as a Delaware business trust (the "Trust"). See
"The Funds."
 
MINIMUM PURCHASE. $500 minimum initial investment for each class of shares and
$25 minimum subsequent investment for each class of shares (or less as described
under "Purchase of Shares").
 
INVESTMENT OBJECTIVES.  The INSURED FUND'S investment objective is to provide
investors with a high level of current income exempt from federal income taxes,
with liquidity and safety of principal, primarily through investment in a
diversified portfolio of insured municipal securities.
 
  The CALIFORNIA INSURED FUND'S investment objective is to provide only
California investors with a high level of current income exempt from federal and
California income taxes, with liquidity and safety of principal, primarily
through investment in a diversified portfolio of insured California municipal
securities. THE CALIFORNIA INSURED FUND IS AVAILABLE ONLY TO CALIFORNIA
RESIDENTS. Distribution to corporations subject to the California franchise tax
will be included in such corporation's gross income for purposes of determining
the California franchise tax. In addition, corporations subject to the
California corporate income tax may, in certain circumstances, be subject to
such taxes with respect to distributions from the California Insured Fund.
Accordingly, an investment in shares of the California Insured Fund may not be
appropriate for corporations subject to either tax. See "Tax Status."
 
INVESTMENT POLICIES. Municipal securities in which the Insured Fund and
California Insured Fund (each a "Fund" or collectively the "Funds") may invest
include fixed and variable rate securities, municipal notes, municipal leases,
tax exempt commercial paper, custodial receipts, participation certificates and
derivative municipal securities the terms of which include elements of, or are
similar in effect to, certain Strategic Transactions (as defined herein) in
which the Funds may engage. Each Fund may invest up to 15% of its total assets
in derivative variable rate securities such as inverse floaters, whose rates
vary inversely with changes in market rates of interest or range or capped
floaters, whose rates are subject to periodic or lifetime caps. There is no
assurance that either Fund will achieve its investment objectives. The net asset
value per share of the Funds may increase or decrease depending on changes in
interest rates and other factors affecting the municipal credit markets. See
"Investment Objectives and Policies."
 
INVESTMENT PRACTICES.  In certain circumstances the Funds may enter into when-
issued or delayed delivery transactions and various strategic transactions,
which entail certain risks. See "Municipal Securities" and "Investment
Practices."
 
                                        4

INSURANCE.  Each municipal security in the portfolio of the respective Funds is
insured as to the timely payment of principal and interest under one or more
policies obtained by the issuer or purchased by such Fund. No representation is
made as to the ability of any insurer to perform its obligations. See
"Insurance."
 
INVESTMENT RESULTS.  The investment results of the Funds are shown in the tables
under the captions "Financial Highlights -- Insured Fund" and "Financial
Highlights -- California Insured Fund."
 
ALTERNATIVE SALES ARRANGEMENTS.  The Alternative Sales Arrangements permit an
investor to choose the method of purchasing shares that is more beneficial to
the investor, taking into account the amount of the purchase, the length of time
the investor expects to hold the shares and other circumstances. Investors
should consider such factors together with the amount of sales charges and
accumulated distribution and service fees with respect to each class of shares
that may be incurred over the anticipated duration of their investment in the
Fund. To assist investors in making this determination, the tables under the
captions "Annual Fund Operating Expenses and Example -- Insured Fund" and
"Annual Fund Operating Expenses and Example -- California Insured Fund," set
forth examples of the charges applicable to each class of shares.
 
  Each Fund currently offer three classes of shares which may be purchased at a
price equal to their net asset value per share plus sales charges which, at the
election of the investor, may be imposed either (i) at the time of purchase
("Class A Shares") or (ii) on a contingent deferred basis (Class A Share
accounts over $1 million, "Class B Shares" and "Class C Shares"). Class A Share
accounts over $1 million or otherwise subject to a contingent deferred sales
charge ("CDSC"), Class B Shares and Class C Shares sometimes are referred to
herein collectively as "CDSC Shares."
 
  Class A Shares. Class A Shares of the Insured Fund are subject to an initial
sales charge equal to 4.75% of the public offering price (4.99% of the net
amount invested), reduced on investments of $100,000 or more. Class A Shares of
the California Insured Fund are subject to an initial sales charge equal to
3.25% of the public offering price (3.36% of the net amount invested), reduced
on investments of $25,000 or more. Class A Shares are subject to ongoing
distribution and service fees at an aggregate annual rate of up to 0.25% of the
respective Fund's average daily net assets attributable to the Class A Shares.
Certain purchases of Class A Shares qualify for reduced or no initial sales
charges and may be subject to a CDSC.
 
  Class B Shares. Class B Shares do not incur a sales charge when they are
purchased. Class B Shares of the Insured Fund are subject to a CDSC if redeemed
within six years of purchase, which charge is equal to 4.00% of the lesser of
the then current net asset value or the original purchase price of such shares
in the first year after purchase and is reduced each year thereafter. Class B
Shares of the California Insured Fund are subject to a CDSC if redeemed within
four years of purchase, which charge is equal to 3.00% of the lesser of the then
current net asset value or
 
                                        5
<PAGE>   87
 
   
the original purchase price of such shares in the first year after purchase and
is reduced each year thereafter. Class B Shares are subject to ongoing
distribution and service fees at an aggregate annual rate of up to 1.00% of the
respective Fund's average daily net assets attributable to the Class B Shares.
Class B Shares of each Fund automatically convert to Class A Shares of the
respective Fund eight years after the end of the calendar month in which the
investor's order to purchase was accepted.
    
 
   
  Class C Shares. Class C Shares do not incur a sales charge when they are
purchased. Class C Shares are subject to a CDSC equal to 1.00% of the lesser of
the then current net asset value or the original purchase price on Class C
Shares redeemed during the first year after purchase. Class C Shares are subject
to ongoing distribution and service fees at an aggregate annual rate of up to
1.00% of the respective Fund's average daily net assets attributable to the
Class C Shares.
    
 
REDEMPTION.  Class A Shares may be redeemed at net asset value without charge,
subject to conditions set forth herein. CDSC Shares may be redeemed at net asset
value less a deferred sales charge which will vary between the Funds and among
each class of CDSC Shares and with the length of time a redeeming shareholder
has owned such shares. CDSC Shares redeemed after the expiration of the CDSC
period applicable to the respective class of CDSC Shares will not be subject to
a deferred sales charge. See "Redemption of Shares."
 
   
INVESTMENT ADVISER.  Van Kampen American Capital Investment Advisory Corp. (the
"Adviser") is the investment adviser for each Fund.
    
 
   
DISTRIBUTOR.  Van Kampen American Capital Distributors, Inc. (the "Distributor")
distributes the shares of each Fund.
    
 
DISTRIBUTIONS FROM THE FUNDS.  Distributions from net investment income are
declared daily and paid monthly; net realized capital gains, if any, are
distributed annually. Distributions with respect to each class of shares will be
calculated in the same manner and the same day and will be in the same amount
except that the different distribution and service fees and administrative
expenses relating to each class of shares will be borne exclusively by the
respective class. See "Distributions from the Funds."
 
   
  The foregoing is qualified in its entirety by reference to the more detailed
    
              information appearing elsewhere in this Prospectus.

(1) Includes a service fee of up to 0.25% (as a percentage of net asset value)
    paid by the Insured Fund as compensation for ongoing services rendered to
    investors. With respect to each class of shares, amounts in excess of 0.25%,
    if any, represent an asset based sales charge. The asset based sales charge
    with respect to Class C Shares includes 0.75% (as a percentage of net asset
    value) paid to investors' brokers, dealers or financial intermediaries as
    sales compensation.
    
 
   
(2) The Insured Fund's distribution and service plans with respect to Class A
    Shares provide that 12b-1 and service fees are charged only with respect to
    Class A Shares of the Insured Fund sold after the implementation date of
    such plans. Due to the incremental "phase-in" of such plans with respect to
    Class A Shares, it is anticipated that 12b-1 and service fees attributable
    to Class A Shares will increase in accordance with such plans to a maximum
    aggregate amount of 0.25% of the net assets attributable to the Insured
    Fund's Class A Shares. Accordingly, it is unlikely that future expenses will
    remain consistent with those disclosed in the fee table. See "Distribution
    and Service Plans."

* Based on conversion to Class A Shares after eight years.
    
 
   
  The purpose of the foregoing table is to assist an investor in understanding
the various costs and expenses that an investor in the Insured Fund will bear
directly or indirectly. The "Example" reflects expenses based on the "Annual
Fund Operating Expenses" table as shown above carried out to future years. Due
to the incremental "phase-in" of the Insured Fund's 12b-1 plans and service
plans, it is anticipated that 12b-1 and service fees applicable to Insured Fund
will increase in accordance with such plans to a maximum amount of 0.25% of such
Fund's net assets. The ten year amount with respect to the Class B Shares of the
Insured Fund reflects the lower aggregate 12b-1 and service fees applicable to
such shares after conversion to Class A Shares. Class B Shares acquired through
the exchange privilege are subject to the deferred sales charge schedule
relating to the Class B Shares of the fund from which the purchase of Class B
Shares was originally made. Accordingly, future expenses as projected could be
higher than those determined in the above table if the investor's Class B Shares
were exchanged from a fund with a higher contingent deferred sales charge. THE
INFORMATION CONTAINED IN THE ABOVE TABLE SHOULD NOT BE CONSIDERED A
REPRESENTATION OF PAST OR FUTURE EXPENSES AND ACTUAL EXPENSES MAY BE GREATER OR
LESSER THAN THOSE SHOWN. For a more complete description of such costs and
expenses, see "Purchase of Shares," "Redemption of Shares," "Investment Advisory
Services" and "Distribution and Service Plans."

EXAMPLES:
 
   
  You would pay the following expenses on a $1,000 investment in the California
Insured Fund, assuming (i) an operating expense ratio of 1.02% for Class A
Shares, 1.79% for Class B Shares and 1.79% for Class C Shares, (ii) a 5% annual
return and (iii) redemption at the end of each time period. California Insured
Fund does not charge a fee for redemptions (other than any applicable contingent
deferred sales charge):

* Based on conversion to Class A Shares after eight years.
    
 
   
  The purpose of the foregoing table is to assist an investor in understanding
the various costs and expenses that an investor in the California Insured Fund
will bear directly or indirectly. The "Example" reflects expenses based on the
"Annual Fund Operating Expenses" table as shown above carried out to future
years. Additionally, as the California Insured Fund's assets increase, the fees
waived or expenses reimbursed by the Adviser are expected to decrease.
Accordingly, it is unlikely that future expenses as projected will remain
consistent with those determined based on the table of the "Annual Fund
Operating Expenses." The ten year amount with respect to the Class B Shares of
the California Insured Fund reflects the lower aggregate 12b-1 and service fees
applicable to such shares after conversion to Class A Shares. Class B Shares
acquired through the exchange privilege are subject to the deferred sales charge
schedule relating to the Class B Shares of the fund from which the purchase of
Class B Shares was originally made. Accordingly, future expenses as projected
could be higher than those determined in the above table if the investor's Class
B Shares were exchanged from a fund with a higher contingent deferred sales
charge. THE INFORMATION CONTAINED IN THE ABOVE TABLE SHOULD NOT BE CONSIDERED A
REPRESENTATION OF PAST OR FUTURE EXPENSES AND ACTUAL EXPENSES MAY BE GREATER OR
LESSER THAN THOSE SHOWN. For a more complete description of such costs and
expenses, see "Purchase of Shares," "Redemption of Shares," "Investment Advisory
Services" and "Distribution and Service Plans."

INVESTMENT OBJECTIVES AND POLICIES
- ------------------------------------------------------------------------------
 
  INSURED FUND.  The investment objective of the Insured Fund is to provide
investors with a high level of current income exempt from federal income taxes,
with liquidity and safety of principal, primarily through investment in a
diversified portfolio of insured municipal securities. All of the municipal
securities in the Insured Fund's portfolio, except for investments in tax exempt
money market funds as noted below, will be insured as to timely payment of both
principal and interest. However, there are market risks inherent in all
investments in securities; accordingly there can be no assurance that the
Insured Fund will achieve its objective.
 
  The Insured Fund will generally invest all of its assets in municipal
securities, the interest on which, in the opinion of bond counsel or other
counsel to the issuer of such securities, is exempt from federal income tax. See
"Municipal Securities." From time to time the Insured Fund temporarily may also
invest up to 10% of its assets in tax exempt money market funds. Such
instruments will be treated as investments in municipal securities.
 
  CALIFORNIA INSURED FUND.  The investment objective of the California Insured
Fund is to provide only California investors with a high level of current income
exempt from federal and California income taxes, with liquidity and safety of
principal, primarily through investment in a diversified portfolio of insured
California municipal securities. All of the municipal securities in the
California Insured Fund's portfolio, except for investments in tax exempt money
funds as noted below, will be insured as to timely payment of both principal and
interest. However, there are market risks inherent in all investments in
securities; and accordingly there can be no assurance that the California
Insured Fund will achieve its objective. THE CALIFORNIA INSURED FUND IS
AVAILABLE ONLY TO RESIDENTS OF CALIFORNIA.
 
                                       17
<PAGE>   99
 
  The California Insured Fund will generally invest all of its assets in
California municipal securities, the interest on which, in the opinion of bond
counsel or other counsel to the issuer of such securities, is exempt from
federal and California income tax. Distribution to corporations subject to the
California franchise tax will be included in such corporation's gross income for
purposes of determining the California franchise tax. In addition, corporations
subject to the California corporate income tax may, in certain circumstances, be
subject to such taxes with respect to distributions from the California Insured
Fund. Accordingly, an investment in shares of the California Insured Fund may
not be appropriate for corporations subject to either tax. See "Municipal
Securities" and "Tax Status." From time to time the California Insured Fund
temporarily may also invest up to 10% of its assets in California tax exempt
money market funds. Such instruments will be treated as investments in municipal
securities.
 
  Investments in the Funds may not be appropriate for all investors. The Funds
are not intended to be a complete investment program, and investors should
consider their long-term investment goals and financial needs when making an
investment decision with respect to the Funds. Investments in the Funds are
intended to be long-term investments and should not be used as trading vehicles.
 
- ------------------------------------------------------------------------------
MUNICIPAL SECURITIES
- ------------------------------------------------------------------------------
 
  GENERAL.  Tax-exempt municipal securities are debt obligations issued by or on
behalf of the governments of states, territories or possessions of the United
States, the District of Columbia and their political subdivisions, agencies and
instrumentalities, certain interstate agencies and certain territories of the
United States, the interest on which, in the opinion of bond counsel or other
counsel to the issuer of such securities, is exempt from federal income tax.
Under normal market conditions, up to 100% but not less than 80%, of each of the
Fund's assets will be invested in such municipal securities. The foregoing is a
fundamental policy of each of the Funds and cannot be changed without approval
of the shareholders of the respective Fund.
 
  The two principal classifications of municipal securities are "general
obligation" and "revenue" securities. "General obligation" securities are
secured by the issuer's pledge of its faith, credit and taxing power for the
payment of principal and interest. "Revenue" securities are usually payable only
from the revenues derived from a particular facility or class of facilities or,
in some cases, from the proceeds of a special excise tax or other specific
revenue source. Industrial development bonds are usually revenue securities, the
credit quality of which is normally directly related to the credit standing of
the industrial user involved.
 
  Within these principal classifications of municipal securities there are a
variety of categories of municipal securities, including fixed and variable rate
securities, municipal bonds, municipal notes, municipal leases, custodial
receipts, participation certificates and derivative municipal securities the
terms of which include elements
 
                                       18
<PAGE>   100
 
of, or are similar in effect to, certain Strategic Transactions (as defined
below) in which the Funds may engage. Variable rate securities bear rates of
interest that are adjusted periodically according to formulae intended to
reflect market rates of interest and include securities whose rates vary
inversely with changes in market rates of interest. Neither Fund will invest
more than 15% of its total assets in derivative municipal securities such as
inverse floaters, whose rates vary inversely with changes in market rates of
interest, or range floaters or capped floaters whose rates are subject to
periodic or lifetime caps. Such securities may also pay a rate of interest
determined by applying a multiple to the variable rate. The extent of increases
and decreases in the value of securities whose rates vary inversely with market
rates of interest generally will be larger than comparable changes in the value
of an equal principal amount of a fixed rate municipal security having similar
credit quality, redemption provisions and maturity. Municipal notes include tax,
revenue and bond anticipation notes of short maturity, generally less than three
years, which are issued to obtain temporary funds for various public purposes.
Municipal leases are obligations issued by state and local governments or
authorities to finance the acquisition of equipment and facilities. Certain
municipal lease obligations may include "non-appropriation" clauses which
provide that the municipality has no obligation to make lease or installment
purchase payments in future years unless money is appropriated for such purpose
on a yearly basis. Some municipal securities may not be backed by the faith,
credit and taxing power of the issuer. Custodial receipts are underwritten by
securities dealers or banks and evidence ownership of future interest payments,
principal payments or both on certain municipal securities. Participation
certificates are obligations issued by state or local governments or authorities
to finance the acquisition of equipment and facilities. They may represent
participations in a lease, an installment purchase contract or a conditional
sales contract. Some municipal securities may not be backed by the faith, credit
and taxing power of the issuer. Certain of the municipal securities in which the
Funds may invest represent relatively recent innovations in the municipal
securities markets. While markets for such recent innovations progress through
stages of development, such markets may be less developed than more fully
developed markets for municipal securities. A more detailed description of the
types of municipal securities in which the Funds may invest is included in each
Fund's Statement of Additional Information.
 
  The net asset value of each of the Funds will change with changes in the value
of their respective portfolio securities. Because the Funds will invest
primarily in fixed income municipal securities, the net asset value of each of
the Funds can be expected to change as general levels of interest rates
fluctuate. When interest rates decline, the value of a portfolio invested in
fixed income securities generally can be expected to rise. Conversely, when
interest rates rise, the value of a portfolio invested in fixed income
securities generally can be expected to decline. Volatility may be greater
during periods of general economic uncertainty.
 
  From time to time, proposals have been introduced before Congress that would
have the effect of reducing or eliminating the federal tax exemption on
municipal
 
                                       19
<PAGE>   101
 
securities. If such a proposal were enacted, the ability of the Funds to pay tax
exempt interest dividends might be adversely affected.
 
  INSURED MUNICIPAL SECURITIES.  With respect to its investments in municipal
securities, each of the Insured Fund and the California Insured Fund may invest
only in municipal securities insured under one of the insurance policies meeting
the standards described in this Prospectus. See "Insurance." Although each
insurer's quality standards may vary from time to time, such insurers generally
insure only those municipal securities that are rated at the date of purchase
(1) in the case of long-term debt, in the four highest ratings by Standard &
Poor's Ratings Group (S&P) (AAA, AA, A and BBB) or by Moody's Investors Service,
Inc. (Moody's) (Aaa, Aa, A and Baa); (2) in the case of short-term notes, SP-1+
through SP-2 by S&P or MIG 1 through MIG 4 by Moody's; or (3) in the case of
tax-exempt commercial paper, A-1+ through A-2 by S&P or Prime-1 through Prime-2
by Moody's. Such ratings are relative and subjective and are not absolute
standards of quality. Any insurer may also insure, and each of the Insured Fund
and California Insured Fund may invest in, unrated municipal securities of
similar quality, as determined by the Adviser, if such securities meet the
insurance standards of such insurer. The Insured Fund and California Insured
Fund may invest, without limitation as to rating category, in any securities for
which such Funds obtain insurance coverage. For a description of such ratings
see the respective Fund's Statement of Additional Information incorporated by
reference into this Prospectus.
 
  SPECIAL CONSIDERATIONS REGARDING CALIFORNIA MUNICIPAL SECURITIES.  Investors
should be aware of certain factors that might affect the financial condition of
the issuers of California municipal securities. With respect to an investment in
the Fund, through popular initiative and legislative activity, the ability of
the State of California (the "State") and its local governments to raise money
through property taxes and to increase spending has been the subject of
considerable debate and change in recent years. Various State Constitutional
amendments, for example, have been adopted which have the effect of limiting
property tax and spending increases, while legislation has sometimes added to
these limitations and has at other times sought to reduce their impact. To date,
these Constitutional, legislative and budget developments do not appear to have
severely decreased the ability of the State and local governments to pay
principal and interest on their obligations. It can be expected that similar
types of State legislation or Constitutional proposals will continue to be
introduced. The impact of future developments in these areas is unclear.
 
  From 1990 until 1994, the State experienced the worst economic, fiscal and
budget conditions since the 1930's. The recession seriously affected State tax
revenues and caused increased expenditures for health and welfare programs. As a
result, the State faced several budget imbalances and used up many of its
available cash resources. Accordingly, rating agencies have reduced the State's
credit ratings several times during recent years.
 
                                       20
<PAGE>   102
 
  Although revenue obligations of the State of California or its political
subdivisions may be payable from a specific project or source, including lease
rentals, there can be no assurance that future economic difficulties and the
resulting impact on State and local government finances will not adversely
affect the market value of the portfolio of the Fund or the ability of the
respective obligors to make timely payments of principal and interest on such
obligations.
 
  More detailed information concerning California municipal securities is
included in the California Insured Fund's Statement of Additional Information.
 
  SELECTION OF INVESTMENTS.  The Adviser will buy and sell securities for each
Fund's portfolio with a view to seeking a high level of current income exempt
from federal income tax and will select securities which the Adviser believes
entail reasonable credit risk considered in relation to the particular
investment policies of such Fund. As a result, the Funds will not necessarily
invest in the highest yielding tax-exempt municipal securities permitted by
their respective investment policies if the Adviser determines that market risks
or credit risks associated with such investments would subject a Fund's
portfolio to excessive risk. The potential for realization of capital gains
resulting from possible changes in interest rates will not be a major
consideration. There is no limitation as to the maturity of municipal securities
in which a Fund may invest. The Adviser may adjust the average maturity of a
Fund's portfolio from time to time, depending on its assessment of the relative
yields available on securities of different maturities and its expectations of
future changes in interest rates. Other than for tax purposes, frequency of
portfolio turnover will generally not be a limiting factor if any of the Funds
considers it advantageous to purchase or sell securities. The Funds may have
annual portfolio turnover rates in excess of 100%. A high rate of portfolio
turnover involves correspondingly greater brokerage commission expenses or
dealer costs than a lower rate, which expenses and costs must be borne by the
respective Fund and its shareholders. High portfolio turnover may also result in
the realization of substantial net short-term capital gains and any
distributions resulting from such gains will be taxable. See "Tax Status."
 
  DEFENSIVE STRATEGIES.  At times conditions in the markets for tax-exempt
municipal securities may, in the Adviser's judgment, make pursuing a Fund's
basic investment strategy inconsistent with the best interests of its
shareholders. At such times, the Adviser may use alternative strategies
primarily designed to reduce fluctuations in the value of such Fund's assets. In
implementing these "defensive" strategies, a Fund may invest to a substantial
degree in high-quality, short-term municipal obligations. If these high-quality,
short-term municipal obligations are not available or, in the Adviser's
judgment, do not afford sufficient protection against adverse market conditions,
such Fund may invest in taxable obligations. Such taxable obligations may
include: obligations of the U.S. Government, its agencies or instrumentalities;
other debt securities rated within the four highest grades by either S&P or
Moody's; commercial paper rated in the highest grade by either rating service;
certificates of deposit and bankers' acceptances; repurchase
 
                                       21
<PAGE>   103
 
agreements with respect to any of the foregoing investments; or any other fixed-
income securities that the Adviser considers consistent with such strategy.
 
- ------------------------------------------------------------------------------
INVESTMENT PRACTICES
- ------------------------------------------------------------------------------
 
  In connection with the investment policies described above, the Funds also may
engage in strategic transactions and purchase and sell securities on a "when
issued" and "delayed delivery" basis. These investments entail risks. Strategic
transactions generally will not be treated as investments in tax-exempt
municipal securities for purposes of the Funds' 80% investment policy with
respect thereto.
 
  STRATEGIC TRANSACTIONS.  The Funds may purchase and sell derivative
instruments such as exchange-listed and over-the-counter put and call options on
securities, financial futures, fixed-income indices and other financial
instruments, purchase and sell financial futures contracts and enter into
various interest rate transactions such as swaps, caps, floors or collars.
Collectively, all of the above are referred to as "Strategic Transactions."
Strategic Transactions may be used to attempt to protect against possible
changes in the market value of securities held in or to be purchased for a
Fund's portfolio resulting from securities markets, to protect such Fund's
unrealized gains in the value of its portfolio securities, to facilitate the
sale of such securities for investment purposes, to manage the effective
maturity or duration of such Fund's portfolio, or to establish a position in the
derivatives markets as a temporary substitute for purchasing or selling
particular securities. Any or all of these investment techniques may be used at
any time and there is no particular strategy that dictates the use of one
technique rather than another, as use of any Strategic Transaction is a function
of numerous variables including market conditions. The ability of a Fund to
utilize these Strategic Transactions successfully will depend on the Adviser's
ability to predict pertinent market movements, which cannot be assured. The
Funds will comply with applicable regulatory requirements when implementing
these strategies, techniques and instruments. Strategic Transactions involving
financial futures and options thereon will be purchased, sold or entered into
only for bona fide hedging, risk management or portfolio management purposes and
not for speculative purposes.
 
  Strategic Transactions have risks associated with them including possible
default by the other party to the transaction, illiquidity and, to the extent
the Adviser's view as to certain market movements is incorrect, the risk that
the use of such Strategic Transactions could result in losses greater than if
they had not been used. Use of put and call options may result in losses to a
Fund, force the sale of portfolio securities at inopportune times or for prices
other than at current market values, limit the amount of appreciation such Fund
can realize on its investments or cause the Fund to hold a security it might
otherwise sell. The use of options and futures transactions entails certain
other risks. In particular, the variable degree of correlation between price
movements of futures contracts and price movements in the related portfolio
position of a Fund creates the possibility that losses on the hedging instrument
may be greater than gains in the value of such Fund's position. In addition,
futures and
 
                                       22
<PAGE>   104
 
options markets may not be liquid in all circumstances and certain
over-the-counter options may have no markets. As a result, in certain markets, a
Fund might not be able to close out a transaction without incurring substantial
losses, if at all. Although the contemplated use of these futures contracts and
options thereon should tend to minimize the risk of loss due to a decline in the
value of the hedged position, at the same time they tend to limit any potential
gain which might result from an increase in value of such position. Finally, the
daily variation margin requirements for futures contracts would create a greater
ongoing potential financial risk than would purchases of options, where the
exposure is limited to the cost of the initial premium. Losses resulting from
the use of Strategic Transactions would reduce net asset value, and possibly
income, and such losses can be greater than if the Strategic Transactions had
not been utilized. The Strategic Transactions that a Fund may use and some of
their risks are described more fully in the respective Fund's Statement of
Additional Information.
 
  Income earned or deemed to be earned, if any, by a Fund from its Strategic
Transactions will be distributed to its shareholders in taxable distributions.
See "Tax Status."
 
   
  "WHEN ISSUED" AND "DELAYED DELIVERY" TRANSACTIONS.  The Funds may also
purchase and sell municipal securities on a "when issued" and "delayed delivery"
basis. No income accrues to the Funds on municipal securities in connection with
such purchase transactions prior to the date the Funds actually take delivery of
such securities. These transactions are subject to market fluctuation; the value
of the municipal securities at delivery may be more or less than their purchase
price, and yields generally available on municipal securities when delivery
occurs may be higher or lower than yields on the municipal securities obtained
pursuant to such transactions. Because the Funds rely on the buyer or seller, as
the case may be, to consummate the transaction, failure by the other party to
complete the transaction may result in the Funds missing the opportunity of
obtaining a price or yield considered to be advantageous. When the Funds are the
buyer in such a transaction, however, they will maintain, in a segregated
account with their custodian, cash or liquid securities having an aggregate
value equal to the amount of such purchase commitments until payment is made.
The Funds will make commitments to purchase municipal securities on such basis
only with the intention of actually acquiring these securities, but the Funds
may sell such securities prior to the settlement date if such sale is considered
to be advisable. No specific limitation exists as to the percentage of each
Fund's assets which may be used to acquire securities on a "when issued" or
"delayed delivery" basis. To the extent a Fund engages in "when issued" and
"delayed delivery" transactions, they will do so for the purpose of acquiring
securities for the respective Fund's portfolio consistent with such Fund's
respective investment objectives and policies and not for the purposes of
investment leverage. No specific limitation exists as to the percentage of a
Fund's assets which may be used to acquire securities on a "when issued" or
"delayed delivery" basis.
    
 
                                       23
<PAGE>   105
 
  OTHER PRACTICES. The Funds have no restrictions on the maturity of municipal
bonds in which they may invest. Each Fund will seek to invest in municipal bonds
of such maturities that, in the judgment of such Fund and the Adviser, will
provide a high level of current income consistent with liquidity requirements
and market conditions.
 
  The Funds may borrow amounts up to 5% of their respective net assets in order
to pay for redemptions when liquidation of portfolio securities is considered
disadvantageous or inconvenient and may pledge up to 10% of their respective net
assets to secure such borrowings.
 
  A Fund generally will not invest more than 25% of its total assets in any
industry, nor will a Fund generally invest more than 5% of its assets in the
securities of any single issuer. Governmental issuers of municipal securities
are not considered part of any "industry." However, municipal securities backed
only by the assets and revenues of nongovernmental users may for this purpose be
deemed to be issued by such nongovernmental users, and the 25% limitation would
apply to such obligations. It is nonetheless possible that a Fund may invest
more than 25% of its assets in a broader segment of the municipal securities
market, such as revenue obligations of hospitals and other health care
facilities, housing agency revenue obligations, or airport revenue obligations
if the Advisor determines that the yields available from obligations in a
particular segment of the market justified the additional risks associated with
a large investment in such segment. Although such obligations could be supported
by the credit of governmental users, or by the credit of nongovernmental users
engaged in a number of industries, economic, business, political and other
developments generally affecting the revenues of such users (for example,
proposed legislation or pending court decisions affecting the financing of such
projects and market factors affecting the demand for their services or products)
may have a general adverse effect on all municipal securities in such a market
segment. The Insured Fund reserves the right to invest more than 25% of its
assets in industrial development bonds or in issuers located in the same state,
although it has no present intention to invest more than 25% of its assets in
issuers located in the same state. If the Insured Fund were to invest more than
25% of its assets in issuers located in the same state, it would be more
susceptible to adverse economic, business, or regulatory conditions in that
state. The California Insured Fund invests primarily in a diversified portfolio
of insured California municipal securities.
 
  ALLOCATION OF BROKERAGE TRANSACTIONS. In effecting purchases and sales of the
Funds' portfolio securities, the Adviser and the Funds may place orders with and
pay brokerage commissions to brokers, including brokers which may be affiliated
with the Funds, the Adviser and the Distributor or dealers participating in the
offering of the Funds' shares. In addition, in selecting among firms to handle a
particular transaction, the Adviser and the Funds may take into account whether
the firm has sold or is selling shares of the Funds.

- ------------------------------------------------------------------------------
INSURANCE
- ------------------------------------------------------------------------------
 
  All of the municipal securities in the portfolios of the Insured Fund and the
California Insured Fund will be insured by municipal bond insurers whose claims-
paying ability is rated "AAA" by S&P on the date of purchase. Timely payment of
all principal and interest of each municipal security in the portfolios of the
Insured Fund and the California Insured Fund either will be pre-insured under a
policy obtained for such securities prior to the purchase of the securities by
such Funds or will be insured under policies obtained by such Funds to cover
otherwise uninsured securities. With respect to municipal securities that are
not pre-insured, the Insured Fund and the California Insured Fund have each
obtained a mutual fund portfolio insurance policy from AMBAC Indemnity
Corporation ("AMBAC") whose claims-paying ability is rated "AAA" by S&P. The
Insured Fund and the California Insured Fund may obtain portfolio insurance from
other insurers in the future. No representation is made as to any insurer's
ability to meet its commitments.
 
  Each insurance policy guarantees the timely payment of all principal and
interest on the municipal securities. Each policy provides, in general, that in
the event of nonpayment of interest or principal, when due, in respect of an
insured municipal security, the insurer is obligated to make such payment not
later than 30 days after it has been notified by the respective Fund that such
nonpayment has occurred (but not earlier than the date when such payment is
due). For these purposes, a payment of principal is due only at scheduled
maturity, including required sinking fund payments and mandatory redemptions, of
the security and not at any earlier time. The insurance does not guarantee the
market value of the municipal securities or the value of the shares of the
Funds.
 
  More detailed information concerning such insurance policies, and concerning
AMBAC, is included in the respective Fund's Statement of Additional Information.

  ADVISORY AGREEMENT.  The business and affairs of each of the Funds will be
managed under the direction of the Board of Trustees of the Trust, of which each
Fund is a separate series. Subject to their authority, the Adviser and the
respective officers of the Funds will supervise and implement the Funds'
investment activities and will be responsible for overall management of the
Funds' business affairs. Each Fund will pay the Adviser a fee equal to a
percentage of the average daily net assets of the respective Fund as follows:

  Under its investment advisory agreement with the Adviser, each Fund has agreed
to assume and pay the charges and expenses of the Fund's operation, including
the compensation of the Trustees of the Trust (other than those who are
affiliated persons, as defined in the Investment Company Act of 1940, as amended
(the "1940 Act"), of the Adviser, the Distributor, or Van Kampen American
Capital),

the charges and expenses of independent accountants, legal counsel, transfer
agent (ACCESS Investor Services, Inc. ("ACCESS"), a wholly-owned subsidiary of
Van Kampen American Capital), or dividend disbursing agent and the custodian
(including fees for safekeeping of securities), costs of calculating net asset
value, costs of acquiring and disposing of portfolio securities, interest (if
any) on obligations incurred by such Fund, costs of share certificates,
membership dues in the Investment Company Institute or any similar organization,
reports and notices to shareholders, costs of registering shares under the
federal securities laws, miscellaneous expenses and all taxes and fees to
federal, state or other governmental agencies. The Adviser reserves the right in
its sole discretion from time-to-time to waive all or a portion of its
management fee or to reimburse a Fund for all or a portion of its other
expenses.
    
 
   
  PERSONAL INVESTING POLICIES.  The Funds and the Adviser have adopted Codes of
Ethics designed to recognize the fiduciary relationship between each Fund and
the Adviser and its employees. The Codes permit directors, trustees, officers
and employees to buy and sell securities for their personal accounts subject to
certain restrictions. Persons with access to certain sensitive information are
subject to preclearance and other procedures designed to prevent conflicts of
interest.
    
 
  PORTFOLIO MANAGEMENT.  Joseph A. Piraro, a Vice President of the Adviser, has
been primarily responsible for the day-to-day management of each Fund's
portfolio since May 1992. Mr. Piraro has been employed by the Adviser since May
1992. Prior to May 1992, Mr. Piraro was employed by First Chicago Capital
Markets.
 
- ------------------------------------------------------------------------------
ALTERNATIVE SALES ARRANGEMENTS
- ------------------------------------------------------------------------------
 
  The Alternative Sales Arrangements permit an investor to choose the method of
purchasing shares that is more beneficial to the investor, taking into account
the amount of the purchase, the length of time the investor expects to hold the
shares, whether the investor wishes to receive dividends in cash or to reinvest
them in additional shares of the Funds, and other circumstances. Investors
should consider such factors together with the amount of sales charges and
accumulated distribution and service fees with respect to each class of shares
that may be incurred over the anticipated duration of their investment in the
Funds.
 
  Each Fund offers three classes of shares, designated Class A Shares, Class B
Shares and Class C Shares. Shares of each class are offered at a price equal to
their net asset value per share plus a sales charge which, at the election of
the purchaser, may be imposed (a) at the time of purchase ("Class A Shares") or
(b) on a contingent deferred basis (Class A Share accounts over $1 million,
"Class B Shares" and "Class C Shares"). Class A Share accounts over $1 million
or otherwise subject to a contingent deferred sales charge ("CDSC"), Class B
Shares and Class C Shares sometimes are referred to herein collectively as
"Contingent Deferred Sales Charge Shares" or "CDSC Shares."
 
                                       27
<PAGE>   109
 
  The minimum initial investment with respect to each class of shares is $500.
The minimum subsequent investment with respect to each class of shares is $25.
It is presently the policy of the Distributor not to accept any order for Class
B Shares in an amount of $500,000 or more and not accept any order for Class C
Shares in an amount of $1 million or more because it ordinarily will be more
advantageous for an investor making such an investment to purchase Class A
Shares.
 
  An investor should carefully consider the sales charges applicable to each
class of shares and the estimated period of their investment to determine which
class of shares is more beneficial for the investor to purchase. For example,
investors who would qualify for a significant purchase price discount from the
maximum sales charge on Class A Shares may determine that payment of such a
reduced front-end sales charge is superior to electing to purchase Class B
Shares or Class C Shares, each with no front-end sales charge but subject to a
CDSC and a higher aggregate distribution and service fee. However, because
initial sales charges are deducted at the time of purchase of Class A Share
accounts under $1 million, a purchaser of such Class A Shares would not have all
of his or her funds invested initially and, therefore, would initially own fewer
shares than if Class B Shares or Class C Shares had been purchased. On the other
hand, an investor whose purchase would not qualify for price discounts
applicable to Class A Shares and intends to remain invested until after the
expiration of the applicable CDSC may wish to defer the sales charge and have
all his or her funds initially invested in Class B Shares or Class C Shares. If
such an investor anticipates that he or she will redeem such shares prior to the
expiration of the CDSC period applicable to Class B Shares, the investor may
wish to acquire Class C Shares. Investors must weigh the benefits of deferring
the sales charge and having all of their funds invested against the higher
aggregate distribution and service fee applicable to Class B Shares and Class C
Shares (discussed below).
 
  Each class of shares represents an interest in the same portfolio of
investments of a Fund and has the same rights, except each class of shares (i)
bears those distribution fees, service fees and administrative expenses
applicable to the respective class of shares as a result of its sales
arrangements, (ii) has exclusive voting rights with respect to those provisions
of the respective Fund's Rule 12b-1 distribution plan which relate only to such
class and (iii) has a different exchange privilege. Generally, a class of shares
subject to a higher ongoing distribution and service fee or subject to the
conversion feature will have a higher expense ratio and pay lower dividends than
a class of shares subject to a lower ongoing distribution and service fee or not
subject to the conversion feature. The per share net asset values of the
different classes of shares are expected to be substantially the same; from time
to time, however, the per share net asset values of the classes may differ. The
net asset value per share of each class of shares of the Funds will be
determined as described in this Prospectus under "Purchase of Shares -- Net
Asset Value."
 
   
  The administrative expenses that may be allocated to a specific class of
shares will consist of (i) ACCESS' expenses attributable to a specific class of
shares,
    
 
                                       28
<PAGE>   110
 
which expenses typically will be higher with respect to classes of shares
subject to the conversion feature; (ii) printing and postage expenses related to
preparing and distributing materials such as shareholder reports, prospectuses
and proxy statements to current shareholders of a specific class; (iii)
Securities and Exchange Commission (the "SEC") registration fees incurred by a
class of shares; (iv) the expense of administrative personnel and services as
required to support the shareholders of a specific class; (v) Trustees' fees or
expense incurred as a result of issues relating to one class of shares; (vi)
accounting expenses relating solely to one class of shares; and (vii) any other
incremental expenses subsequently identified that should be properly allocated
to one or more classes of shares. All such expenses incurred by a class will be
borne on a pro rata basis by the outstanding shares of such class. All
allocations of administrative expenses to a particular class of shares will be
limited to the extent necessary to preserve the respective Fund's qualification
as a regulated investment company under the Internal Revenue Code of 1986, as
amended (the "Code").
 
- ------------------------------------------------------------------------------
PURCHASE OF SHARES
- ------------------------------------------------------------------------------
 
   
  Shares of the Funds are continuously offered through the Distributor, as
principal underwriter, which is located at One Parkview Plaza, Oakbrook Terrace,
Illinois 60181. Shares are also offered through members of the National
Association of Securities Dealers, Inc. ("NASD") acting as securities dealers
("dealers") and through NASD members acting as brokers for investors ("brokers")
or eligible non-NASD members acting as agents for investors ("financial
intermediaries"). Each of the Funds reserves the right to suspend or terminate
the continuous public offering of its shares at any time and without prior
notice.
    
 
  The Funds' shares are offered at the net asset value per share next computed
after an investor places an order to purchase directly with the investor's
broker, dealer or financial intermediary or with the Distributor plus any
applicable sales charge. Sales personnel of brokers, dealers and financial
intermediaries distributing the Funds' shares may receive differing compensation
for selling different classes of shares. It is the responsibility of the
investor's broker, dealer or financial intermediary to transmit the order to the
Distributor. Because the Funds generally will determine net asset value once
each business day as of the close of business, purchase orders placed through an
investor's broker, dealer or financial intermediary must be transmitted to the
Distributor by such broker, dealer or financial intermediary prior to such time
in order for the investor's order to be fulfilled on the basis of the net asset
value to be determined that day. Any change in the purchase price due to the
failure of the Distributor to receive a purchase order prior to such time must
be settled between the investor and the broker, dealer or financial intermediary
submitting the order.
 
  The Distributor may from time to time implement programs under which a broker,
dealer or financial intermediary's sales force may be eligible to win nominal
 
                                       29
<PAGE>   111
 
   
awards for certain sales efforts or under which the Distributor will reallow to
any broker, dealer or financial intermediary that sponsors sales contests or
recognition programs conforming to criteria established by the Distributor, or
participates in sales programs sponsored by the Distributor, an amount not
exceeding the total applicable sales charges on the sales generated by the
broker, dealer or financial intermediary at the public offering price during
such programs. Other programs provide, among other things and subject to certain
conditions, for certain favorable distribution arrangements for shares of the
Funds. Also, the Distributor in its discretion may from time to time, pursuant
to objective criteria established by it, pay fees to, and sponsor business
seminars for, qualifying brokers, dealers or financial intermediaries for
certain services or activities which are primarily intended to result in sales
of shares of the Funds. Fees may include payment for travel expenses, including
lodging, incurred in connection with trips taken by invited registered
representatives and members of their families to locations within or outside of
the United States for meetings or seminars of a business nature. In some
instances additional compensation or promotional incentives may be offered to
brokers, dealers or financial intermediaries that have sold or may sell
significant amounts of shares during specified periods of time. The Distributor
may provide additional compensation to Edward D. Jones & Co. or an affiliate
thereof based on a combination of its sales of shares and increases in assets
under management. Such payments to brokers, dealers and financial intermediaries
for sales contests, other sales programs and seminars are made by the
Distributor out of its own assets and not out of the assets of the Funds. Such
fees paid for such services and activities with respect to a Fund will not
exceed in the aggregate 1.25% of the average total daily net assets of such Fund
on an annual basis. These programs will not change the price an investor will
pay for shares or the amount that the respective Fund will receive from such
sale.
    
 
CLASS A SHARES
 
  The public offering price of Class A Shares is equal to the net asset value
per share plus an initial sales charge which is a variable percentage of the
offering price depending upon the amount of the sale. The tables below with
respect to the Funds show total sales charges and dealer concessions reallowed
to dealers and agency commissions paid to brokers with respect to sales of Class
A Shares. The sales charge is allocated between the investor's broker, dealer or
financial intermediary and the Distributor. As indicated previously, at the
discretion of the Distributor, the entire sales charge may be reallowed to such
broker, dealer or financial intermediary. The staff of the SEC has taken the
position that brokers, dealers and financial intermediaries who receive more
than 90% or more of the sales charge may be deemed to be "underwriters" as that
term is defined in the Securities Act of 1933, as amended.

 * No sales charge is payable at the time of purchase on investments of $1
   million or more, although for such investments the Funds imposes a CDSC of
   1.00% on redemptions made within one year of the purchase. A commission
   will be paid to brokers, dealers or financial intermediaries who initiate
   and are responsible for purchases of $1 million or more as follows: 1.00%
   on sales to $2 million, plus 0.80% on the next $1 million and 0.50% on the
   excess over $3 million. See "Purchase of Shares -- Deferred Sales Charge
   Alternatives" for additional information with respect to CDSCs.
    
 
QUANTITY DISCOUNTS
 
  Investors purchasing Class A Shares may, under certain circumstances, be
entitled to pay reduced sales charges. The circumstances under which such
investors may pay reduced sales charges are described below.
 
  Investors, or their brokers, dealers or financial intermediaries, must notify
the respective Fund whenever a quantity discount is applicable to purchases.
Upon such
 
                                       31
<PAGE>   113
 
notification, an investor will receive the lowest applicable sales charge.
Quantity discounts may be modified or terminated at any time. For more
information about quantity discounts, investors should contact their broker,
dealer or financial intermediary or the Distributor.
 
   
  A person eligible for a reduced sales charge includes an individual, their
spouse and minor children under 21 years of age and any corporation, partnership
or sole proprietorship which is 100% owned, either alone or in combination, by
any of the foregoing; a trustee or other fiduciary of a single trust estate or a
single fiduciary account; or a "company" as defined is section 2(a)(8) of the
1940 Act.
    
 
   
  As used herein, "Participating Funds" refers to certain open-end investment
companies advised by the Adviser or Van Kampen American Capital Asset
Management, Inc. and distributed by the Distributor. Additional funds may be
added from time to time as determined by the Fund's Board of Trustees as
Participating Funds.
    
 
   
  VOLUME DISCOUNTS. The size of investment shown in the preceding sales charge
tables applies to the total dollar amount being invested by any person at any
one time in Class A Shares of a Fund, or in any combination of shares of the
Fund and shares of other Participating Funds, although other Participating Funds
may have different sales charges.
    
 
   
  CUMULATIVE PURCHASE DISCOUNT. The size of investment shown in the preceding
sales charge tables may also be determined by combining the amount being
invested in Class A Shares of a Fund with other shares of such Fund and shares
of Participating Funds, plus the current offering price of all shares of such
Fund and other Participating Funds which have been previously purchased and are
still owned.
    
 
   
  LETTER OF INTENT. A Letter of Intent provides an opportunity for an investor
to obtain a reduced sales charge by aggregating the amount being invested over a
13-month period to determine the sales charge as outlined in the preceding sales
charge tables. The size of investment shown in the preceding table includes the
amount of intended purchases of Class A Shares of a Fund with other shares of
such Fund and shares of the Participating Funds plus the value of all shares of
such Fund and other Participating Funds previously purchased during such
13-month period and still owned. An investor may elect to compute the 13-month
period starting up to 90 days before the date of execution of a Letter of
Intent. Each investment made during the period receives the reduced sales charge
applicable to the total amount of the investment goal. If trades not initially
made under a Letter of Intent subsequently qualify for a lower sales charge
through the 90-day back-dating provision, an adjustment will be made at the
expiration of the Letter of Intent to give effect to the lower charge. If the
goal is not achieved within the 13-month period, the investor must pay the
difference between the sales charge applicable to the purchases made and the
sales charges previously paid. When an investor signs a Letter of Intent, shares
equal to at least 5% of the total purchase
    
 
                                       32
<PAGE>   114
 
amount of the level selected will be restricted from sale or redemption by the
investor until the Letter of Intent is satisfied or any additional sales charges
have been paid; if the Letter of Intent is not satisfied by the investor and any
additional sales charges are not paid, sufficient restricted shares will be
redeemed by the Fund to pay such charges. Additional information is contained in
the application accompanying this Prospectus.
 
OTHER PURCHASE PROGRAMS
 
   
  Purchasers of Class A Shares may be entitled to reduced initial sales charges
in connection with unit investment trust reinvestment programs and purchases by
registered representatives of selling firms or purchases by persons affiliated
with the respective Fund or the Distributor. The Funds reserve the right to
modify or terminate these arrangements at any time.
    
 
  UNIT INVESTMENT TRUST REINVESTMENT PROGRAMS. Each of the Funds permits
unitholders of unit investment trusts to reinvest distributions from such trusts
in Class A Shares of such Fund at net asset value with no minimum initial or
subsequent investment requirement if the administrator of an investor's unit
investment trust program meets certain uniform criteria relating to cost savings
by such Fund and the Distributor. The total sales charge for all other
investments made from unit trust distributions will be 1.00% of the offering
price (1.01% of net asset value). Of this amount, the Distributor will pay to
the broker, dealer or financial intermediary, if any, through which such
participation in the qualifying program was initiated 0.50% of the offering
price as a dealer concession or agency commission. Persons desiring more
information with respect to this program, including the applicable terms and
conditions thereof, should contact their broker, dealer, financial intermediary
or the Distributor.
 
   
  The administrator of such a unit investment trust must have an agreement with
the Distributor pursuant to which the administrator will (1) submit a single
bulk order and make payment with a single remittance for all investments in the
respective Fund during each distribution period by all investors who choose to
invest in such Fund through the program and (2) provide ACCESS with appropriate
backup data for each participating investor in a computerized format fully
compatible with ACCESS processing system.
    
 
   
  As further requirements for obtaining these special benefits, the respective
Fund also requires that all dividends and other distributions by such Fund be
reinvested in additional shares without any systematic withdrawal program. There
will be no minimum for reinvestments from unit investment trusts. The Fund will
send account activity statements to such participants on a monthly basis only,
even if their investments are made more frequently. The Fund reserves the right
to modify or terminate this program at any time.

      are made an amount up to 0.50% of the amount invested, over a 12-month
      period following such transaction.
    
 
   
  (5) Trustees and other fiduciaries purchasing shares for retirement plans of
      organizations with retirement plan assets of $3 million or more and which
      invest in multiple fund families through national wirehouse alliance
      programs.
    
 
  (6) Accounts as to which a broker, dealer or financial intermediary charges an
      account management fee ("wrap accounts"), provided the broker, dealer or
      financial intermediary has a separate agreement with the Distributor.
 
  (7) Investors purchasing shares of a Fund with redemption proceeds from other
      mutual fund complexes on which the investor has paid a front-end sales
      charge or was subject to a deferred sales charge, whether or not paid, if
      such redemption has occurred no more than 30 days prior to such purchase.
 
   
  (8) Trusts created under pension, profit sharing or other employee benefit
      plans qualified under Section 401(a) of the Code, or custodial accounts
      held by a bank created pursuant to Section 403(b) of the Code and
      sponsored by non-profit organizations defined under Section 501(c)(3) of
      the Code and assets

      held by an employer or trustee in connection with an eligible deferred
      compensation plan under Section 457 of the Code. Such plans will qualify
      for purchases at net asset value provided, for plans initially
      establishing accounts with the Distributor in the Participating Funds
      after February 1, 1997, that (1) the initial amount invested in the
      Participating Funds is at least $500,000 or (2) such shares are purchased
      by an employer sponsored plan with more than 100 eligible employees. Such
      plans that have been established with a Participating Fund or have
      received proposals from the Distributor prior to February 1, 1997 based on
      net asset value purchase privileges previously in effect will be qualified
      to purchase shares of the Participating Funds at net asset value for
      accounts established on or before May 1, 1997. Section 403(b) and similar
      accounts for which Van Kampen American Capital Trust Company served as
      custodian will not be eligible for net asset value purchases based on the
      aggregate investment made by the plan or the number of eligible employees,
      except under certain uniform criteria established by the Distributor from
      time to time. Prior to February 1, 1997, a commission will be paid to
      authorized dealers who initiate and are responsible for such purchases
      within a rolling twelve-month period as follows: 1.00% on sales to $5
      million, plus 0.50% on the next $5 million and 0.25% on the excess over
      $10 million. For purchases on February 1, 1997 and thereafter, a
      commission will be paid as follows: 1.00% on sales to $2 million, plus
      0.80% on the next $1 million, plus 0.50% on the next $47 million and 0.25%
      on the excess over $50 million.
    
 
   
  (9) Individuals who are members of a "qualified group". For this purpose, a
      qualified group is one which (i) has been in existence for more than six
      months, (ii) has a purpose other than to acquire shares of the Fund or
      similar investments, (iii) has given and continues to give its endorsement
      or authorization, on behalf of the group, for purchase of shares of the
      Fund and other Participating Funds, (iv) has a membership that the
      authorized dealer can certify as to the group's members and (v) satisfies
      other uniform criteria established by the Distributor for the purpose of
      realizing economics of scale in distributing such shares. A qualified
      group does not include one whose sole organizational nexus, for example,
      is that its participants are credit card holders of the same institution,
      policy holders of an insurance company, customers of a bank or
      broker-dealer, clients of an investment adviser or other similar groups.
      Shares purchased in each group's participants account in connection with
      this privilege will be subject to a CDSC of 1.00% in the event of
      redemption within one year of purchase, and a commission will be paid to
      authorized dealers who initiate and are responsible for such sales to each
      individual as follows: 1.00% on sales to $2 million, plus 0.80% on the
      next $1 million and 0.50% on the excess over $3 million.
    
 
   
The term "families" includes a person's spouse, children under 21 years of age
and grandchildren, parents, and a person's spouse's parents.

  Purchase orders made pursuant to clause (4) may be placed either through
authorized brokers, dealers or financial intermediaries as described above or
directly with ACCESS, the investment adviser, trust company or bank trust
department, provided that ACCESS receives federal funds for the purchase by the
close of business on the next business day following acceptance of the order. An
authorized broker, dealer or financial intermediary may charge a transaction fee
for placing an order to purchase shares pursuant to this provision or for
placing a redemption order with respect to such shares. The Funds may terminate,
or amend the terms of, offering shares of the Funds at net asset value to such
groups at any time.
    
 
DEFERRED SALES CHARGE ALTERNATIVES
 
   
  Investors choosing the deferred sales charge alternative may purchase Class A
Shares in an amount of $1 million or more, Class B Shares or Class C Shares. The
public offering price of a CDSC Share is equal to the net asset value per share
without the imposition of a sales charge at the time of purchase. CDSC Shares
are sold without an initial sales charge so that the Funds may invest the full
amount of the investor's purchase payment. The Distributor will compensate
brokers, dealers and financial intermediaries participating in the continuous
public offering of the CDSC Shares out of its own assets, and not out of the
assets of the respective Fund, at a percentage rate of the dollar value of the
CDSC Shares purchased from such Fund by such brokers, dealers and financial
intermediaries, which percentage rate will be equal to (i) with respect to Class
A Shares, 1.00% on sales to $2 million, plus 0.80% on the next $1 million and
0.50% on the excess over $3 million; (ii) 4.00% with respect to Class B Shares
of the Insured Fund; (iii) 3.00% with respect to Class B Shares of the
California Insured Fund; and (iv) 1.00% with respect to Class C Shares of each
Fund. Such compensation will not change the price an investor will pay for CDSC
Shares or the amount that the respective Fund will receive from such sale.
    
 
   
  CDSC Shares redeemed within a specified period of time generally will be
subject to a CDSC at the rates set forth below charged as a percentage of the
dollar amount subject thereto. The amount of the CDSC will vary depending on (i)
the class of CDSC Shares to which such shares belong and (ii) the number of
years from the time of payment for the purchase of the CDSC Shares until the
time of their redemption. The charge will be assessed on an amount equal to the
lesser of the then current market value or the original purchase price of the
CDSC Shares being redeemed. Accordingly, no sales charge will be imposed on
increases in net asset value above the initial purchase price. In addition, no
CDSC will be assessed on CDSC Shares derived from reinvestment of dividends or
capital gains distributions. Solely for purposes of determining the number of
years from the time of any payment for the purchase of CDSC Shares, all payments
during a month will be aggregated and deemed to have been made on the last day
of the month.
    
 
   
  Proceeds from the CDSC and the distribution fee applicable to a class of CDSC
Shares are paid to the Distributor and are used by the Distributor to defray its
    
 
                                       36
<PAGE>   118
 
   
expenses related to providing distribution related services to the respective
Fund in connection with the sale of shares of such class of CDSC Shares, such as
the payment of compensation to selected dealers and agents for selling such
shares. The combination of the CDSC and the distribution fees facilitates the
ability of the respective Fund to sell such CDSC Shares without a sales charge
being deducted at the time of purchase.
    
 
   
  In determining whether a CDSC is applicable to a redemption of CDSC Shares, it
will be assumed that the redemption is made first of any CDSC Shares acquired
pursuant to reinvestment of dividends or distributions, second of CDSC Shares
that have been held for a sufficient period of time such that the CDSC no longer
is applicable to such shares, third of Class A Shares in the shareholder's Fund
account that have converted from Class B Shares or Class C Shares, if any, and
fourth of CDSC Shares held longest during the period of time that a CDSC is
applicable to such CDSC Shares. The charge will not be applied to dollar amounts
representing an increase in the net asset value per share since the time of
purchase.
    
 
  To provide an example, assume an investor purchased 100 Class B Shares of the
Insured Fund (as set forth below) at $10 per share (at a cost of $1,000) and in
the second year after purchase, the net asset value per share is $12 and, during
such time, the investor has acquired 10 additional Class B Shares upon dividend
reinvestment. If at such time the investor makes his first redemption of 50
shares (proceeds of $600), 10 shares will not be subject to charge because of
dividend reinvestment. With respect to the remaining 40 shares, the charge is
applied only to the original cost of $10 per share and not to the increase in
net asset value of $2 per share. Therefore, $400 of the $600 redemption proceeds
will be charged at a rate of 3.75% (the applicable rate in the second year after
purchase).
 
   
  CLASS A SHARE PURCHASES OF $1 MILLION OR MORE. No sales charge is payable at
the time of purchase on investments in Class A Shares of $1 million or more,
although for such investments the respective Fund may impose a CDSC of 1.00% on
redemptions made within one year of the purchase. A commission will be paid to
dealers who initiate and are responsible for purchases of $1 million or more as
follows: 1.00% on sales to $2 million, plus 0.80% on the next $1 million and
0.50% on the excess over $3 million.

<PAGE>   119
 
   
  CLASS B SHARES. Class B Shares redeemed within the number of years of purchase
set forth below generally will be subject to a CDSC at the rates set forth
below, charged as a percentage of the dollar amount subject thereto:

  The CDSC generally is waived on redemptions of Class B Shares made pursuant to
the Systematic Withdrawal Plan. See "Shareholder Services -- Systematic
Withdrawal Plan."
    
 
   
  CLASS C SHARES. Class C Shares of each Fund redeemed within the first twelve
months of purchase generally will be subject to a CDSC of 1.00% of the dollar
amount subject thereto. Class C Shares redeemed thereafter will not be subject
to a contingent deferred sales charge.
    
 
   
  CONVERSION FEATURE. Class B Shares of each Fund purchased on or after June 1,
1996 and any dividend reinvestment plan shares received thereon, automatically
convert to Class A Shares eight years after the end of the calendar month in
which the shares were purchased. Class B Shares of the Insured Fund purchased
before June 1, 1996, and any dividend reinvestment shares received thereon,
automatically convert to Class A Shares seven years after the end of the
calendar month in which
    
 
                                       38
<PAGE>   120
 
   
the shares were purchased. Class B Shares of the California Insured Fund
purchased before June 1, 1996, and any dividend reinvestment plan shares
received thereon, automatically convert to Class A Shares six years after the
end of the calendar month in which the shares were purchased. Class C Shares of
each Fund purchased before January 1, 1997, and any dividend reinvestment plan
shares received thereon, automatically convert to Class A Shares ten years after
the end of the calendar month in which such shares were purchased. Such
conversion will be on the basis of the relative net asset values per share,
without the imposition of any sales load, fee or other charge.
    
 
   
  The conversion of such shares to Class A Shares is subject to the continuing
availability of an opinion of counsel to the effect that (i) the assessment of
the higher distribution and service fees and ACCESS costs with respect to such
shares does not result in a Fund's dividends or distributions constituting
"preferential dividends" under the Internal Revenue Code of 1986, as amended
(the "Code"), and (ii) that the conversion of such shares does not constitute a
taxable event under federal income tax law. The conversion may be suspended if
such an opinion is no longer available and such shares might continue to be
subject to the higher aggregate Fees applicable to such class of shares for an
indefinite period.
    
 
   
  WAIVER OF CONTINGENT DEFERRED SALES CHARGE.  The CDSC is waived on redemptions
of Class B Shares and Class C Shares (i) following the death or disability (as
defined in the Code) of a shareholder, (ii) in connection with required minimum
distributions from an IRA or other retirement plan, (iii) pursuant to the Fund's
systematic withdrawal plan but limited to 12% annually of the initial value of
the account and (iv) effected pursuant to the right of the Fund to liquidate a
shareholder's account as described herein under "Redemption of Shares." The CDSC
also is waived on redemptions of Class C Shares as it relates to the
reinvestment of redemption proceeds in shares of the same class of the Fund
within 120 days after redemption. See "Shareholder Services" and "Redemption of
Shares" for further discussion of the waiver provisions.
    
 
NET ASSET VALUE
 
  The net asset value per share of each of the Funds is determined by
calculating the total value of such Fund's assets, deducting its total
liabilities, and dividing the result by the number of shares of such Fund
outstanding. The net asset value is computed once daily as of 5:00 p.m. Eastern
time, Monday through Friday, except on customary business holidays, or except on
any day on which no purchase or redemption orders are received, or there is not
a sufficient degree of trading in such Fund's portfolio securities such that the
Fund's net asset value per share might be materially affected. Each of the Funds
reserves the right to calculate the net asset value and to adjust the public
offering price based thereon more frequently than once a day if deemed
desirable.
 
  Fixed income securities are valued by using market quotations, prices provided
by market makers or estimates of market values obtained from yield data relating
to
 
                                       39
<PAGE>   121
 
instruments or securities with similar characteristics in accordance with
procedures established in good faith by the Trustees of the Trust, of which each
Fund is a separate series. Short-term securities with remaining maturities of
less than 60 days are valued at amortized cost when amortized cost is determined
in good faith by or under the direction of the Board of Trustees of the Trust to
be representative of the fair value at which it is expected such securities may
be resold. Other assets are valued at fair value as determined in good faith by
or under direction of the Trustees. The net asset values per share of the
different classes of shares are expected to be substantially the same; from time
to time, however, the per share net asset value of the different classes of
shares may differ.
 
- ------------------------------------------------------------------------------
SHAREHOLDER SERVICES
- ------------------------------------------------------------------------------
 
  Each of the Funds offers a number of shareholder services designed to
facilitate investment in its shares at little or no extra cost to the investor.
Below is a description of such services. Unless otherwise described below, each
of these services may be modified or terminated by the respective Fund at any
time.
 
   
  INVESTMENT ACCOUNT. ACCESS, transfer agent for the Funds and a wholly-owned
subsidiary of Van Kampen American Capital, performs bookkeeping, data processing
and administration services related to the maintenance of shareholder accounts.
Each shareholder has an investment account under which shares are held by
ACCESS. Except as described in this Prospectus, after each share transaction in
an account, the shareholder receives a statement showing the activity in the
account. Each shareholder will receive statements at least quarterly from ACCESS
showing any reinvestments of dividends and capital gains distributions and any
other activity in the account since the preceding statement. Such shareholders
also will receive separate confirmations for each purchase or sale transaction
other than reinvestment of dividends and capital gains distributions and
systematic purchases or redemptions. Additions to an investment account may be
made at any time by purchasing shares through authorized brokers, dealers or
financial intermediaries or by mailing a check directly to ACCESS.
    
 
  SHARE CERTIFICATES. Generally, the Funds will not issue share certificates.
However, upon written or telephone request to the respective Fund, a share
certificate will be issued, representing shares (with the exception of
fractional shares) of such Fund. A shareholder will be required to surrender
such certificates upon redemption thereof. In addition, if such certificates are
lost the shareholder must write to Van Kampen American Capital Funds, c/o
ACCESS, P.O. Box 418256, Kansas City, MO 64141-9256, requesting an "affidavit of
loss" and to obtain a Surety Bond in a form acceptable to ACCESS. On the date
the letter is received ACCESS will calculate a fee for replacing the lost
certificate equal to no more than 2.00% of the net asset value of the issued
shares and bill the party to whom the replacement certificate was mailed.
 
                                       40
<PAGE>   122
 
   
  REINVESTMENT PLAN. A convenient way for investors to accumulate additional
shares is by accepting dividends and capital gains distributions in shares of
the respective Fund. Such shares are acquired at net asset value per share
(without sales charge) on the record date of such dividend or distribution.
Unless the shareholder instructs otherwise, the reinvestment plan is automatic.
This instruction may be made by telephone by calling (800) 421-5666 ((800)
421-2833 for the hearing impaired) or in writing to ACCESS. The investor may, on
the initial application or prior to any declaration, instruct that dividends be
paid in cash and capital gains distributions be reinvested at net asset value,
or that both dividends and capital gains distributions be paid in cash. For
further information, see "Distributions from the Funds."
    
 
  AUTOMATIC INVESTMENT PLAN. An automatic investment plan is available under
which a shareholder can authorize ACCESS to charge a bank account on a regular
basis to invest pre-determined amounts in the respective Fund. Additional
information is available from the Distributor or authorized brokers, dealers or
financial intermediaries.
 
   
  DIVIDEND DIVERSIFICATION. A shareholder may, upon written request or by
completing the appropriate section of the application form accompanied by this
Prospectus or by calling (800) 421-5666 ((800) 421-2833 for the hearing
impaired), elect to have all dividends and other distributions paid on a class
of shares of the respective Fund invested into shares of the same class of any
other Participating Fund, Tax Free Money Fund or Reserve Fund so long as a pre-
existing account for such class of shares exists for such shareholder.
    
 
  If the qualified pre-existing account does not exist, the shareholder must
establish a new account subject to minimum investment and other requirements of
the fund into which distributions would be invested. Distributions are invested
into the selected fund at its net asset value as of the payable date of the
distribution only if shares of such selected fund have been registered for sale
in the investor's state.
 
   
  EXCHANGE PRIVILEGE. Shares of a Fund may be exchanged with shares of another
Participating Fund, subject to certain limitations. Before effecting an
exchange, shareholders in the Fund should obtain and read a current prospectus
of the fund into which the exchange is to be made. SHAREHOLDERS MAY ONLY
EXCHANGE INTO SUCH OTHER FUNDS AS ARE LEGALLY AVAILABLE FOR SALE IN THEIR STATE.
    
 
  To be eligible for exchange, shares of a Fund must have been registered in the
shareholder's name for at least 30 days prior to an exchange. Shares of a Fund
registered in a shareholder's name for less than 30 days may only be exchanged
upon receipt of prior approval of the Adviser. Under normal circumstances, it is
the policy of the Adviser not to approve such requests.
 
  Class A Shares of Van Kampen American Capital funds that generally impose an
initial sales charge are not subject to any sales charge upon exchange into a
Fund. Class A Shares of Van Kampen American Capital funds that generally do not
 
                                       41
<PAGE>   123
 
impose an initial sales charge are subject to the appropriate sales charge
applicable to Class A Shares of a Fund.
 
   
  No sales charge is imposed upon the exchange of Class B Shares and Class C
Shares. The CDSC schedule and conversion schedule applicable to a Class B Share
or Class C Share acquired through the exchange privilege is determined by
reference to the Van Kampen American Capital fund from which such share
originally was purchased. The holding period of a Class B Share or Class C Share
acquired through the exchange privilege is determined by reference to the date
such share originally was purchased from a Van Kampen American Capital fund.
    
 
  Exchanges of shares are sales and may result in a gain or loss for federal
income tax purposes. If the shares exchanged have been held for less than 91
days, the sales charge paid on such shares is not included in the tax basis of
the exchanged shares, but is carried over and included in the tax basis of the
shares acquired.
 
   
  A shareholder wishing to make an exchange may do so by sending a written
request to ACCESS or by contacting the telephone transaction line at (800)
421-5684 ((800) 421-2833 for the hearing impaired). A shareholder automatically
has telephone exchange privileges unless otherwise designated in the application
form accompanied by this Prospectus. The exchange will take place at the
relative net asset values of the shares next determined after receipt of such
request with adjustment for any additional sales charge. Any shares exchanged
begin earning dividends on the next business day after the exchange is affected.
Van Kampen American Capital and its subsidiaries, including ACCESS
(collectively, "VKAC"), and the Funds employ procedures considered by them to be
reasonable to confirm that instructions communicated by telephone are genuine.
Such procedures include requiring certain personal identification information
prior to acting upon telephone instructions, tape recording telephone
communications, and providing written confirmation of instructions communicated
by telephone. If reasonable procedures are employed, a shareholder agrees that
neither VKAC nor the respective Fund will be liable for following telephone
instructions which it reasonably believes to be genuine. VKAC and the respective
Fund may be liable for any losses due to unauthorized or fraudulent instructions
if reasonable procedures are not followed. Exchanges are effected at the net
asset value per share next calculated after the request is received in good
order with adjustment for any additional sales charge. If the exchanging
shareholder does not have an account in the fund whose shares are being
acquired, a new account will be established with the same registration, dividend
and capital gains options (except dividend diversification options) and broker,
dealer or financial intermediary of record as the account from which shares are
exchanged, unless otherwise specified by the shareholder. In order to establish
a systematic withdrawal plan for the new account or reinvest dividends from the
new account into another fund, an exchanging shareholder must file a specific
written request. Each of the Funds reserves the right to reject any order to
acquire shares through exchange. In addition, each of the Funds may
    
 
                                       42
<PAGE>   124
 
   
modify, restrict or terminate the exchange privilege at any time on 60 days'
notice to its shareholders of any termination or material amendment.
    
 
   
  A prospectus of any of these mutual funds may be obtained from any broker,
dealer or financial intermediary or the Distributor. An investor considering an
exchange to one of such funds should refer to the prospectus for additional
information regarding such fund prior to investing.
    
 
   
  SYSTEMATIC WITHDRAWAL PLAN. Any investor whose shares in a single account
total $10,000 or more at the offering price next computed after receipt of
instructions may establish a monthly, quarterly, semi-annual or annual
withdrawal plan. Any investor whose shares in a single account total $5,000 or
more at the offering price next computed after receipt of instructions may
establish a quarterly, semi-annual or annual withdrawal plan. This plan provides
for the orderly use of the entire account, not only the income but also the
capital, if necessary. Each withdrawal constitutes a redemption of shares on
which taxable gain or loss will be recognized. The plan holder may arrange for
monthly, quarterly, semi-annual, or annual checks in any amount not less than
$25.
    
 
   
  Holders of Class B Shares and Class C Shares who establish a withdrawal plan
may redeem up to 12% annually of the shareholder's initial account balance
without incurring a contingent deferred sales charge. Initial account balance
means the amount of the shareholder's investment at the time the election to
participate in the plan is made.
    
 
  Under the plan, sufficient shares of a Fund are redeemed to provide the amount
of the periodic withdrawal payment. Dividends and capital gains distributions on
shares held under the plan are reinvested in additional shares at the next
determined net asset value. If periodic withdrawals continuously exceed
reinvested dividends and capital gains distributions, the shareholder's original
investment will be correspondingly reduced and ultimately exhausted. Withdrawals
made concurrently with purchases of additional shares ordinarily will be
disadvantageous to the shareholder because of the duplication of sales charges.
Each of the Funds reserves the right to amend or terminate the systematic
withdrawal program on thirty days' notice to its shareholders.
 
  CHECK WRITING PRIVILEGE. Holders of Class A Shares of the Funds for which
certificates have not been issued and which are in a non-escrow status may
appoint ACCESS as agent by completing the Authorization for Redemption by Check
Form and the appropriate section of the application and returning the form and
the application to ACCESS. Once the form is properly completed, signed and
returned to the agent, a supply of checks drawn on State Street Bank and Trust
Company ("State Street Bank") will be sent to such shareholder. These checks may
be made payable by the holder of Class A Shares to the order of any person in
any amount of $100 or more.
 
  When a check is presented to State Street Bank for payment, full and
fractional Class A Shares required to cover the amount of the check are redeemed
from the
 
                                       43
<PAGE>   125
 
shareholder's account by ACCESS at the next determined net asset value. Check
writing redemptions represent the sale of Class A Shares. Any gain or loss
realized on the sale of Class A Shares is a taxable event. See "Redemption of
Shares."
 
   
  Checks will not be honored for redemption of Class A Shares held less than 15
calendar days, unless such Class A Shares have been paid for by bank wire. Any
Class A Shares for which there are outstanding certificates may not be redeemed
by check. If the amount of the check is greater than the proceeds of all
uncertificated shares held in the shareholder's Class A Share account, the check
will be returned and the shareholder may be subject to additional charges.
Holders of Class A Shares may not liquidate the entire account by means of a
check. The check writing privilege may be terminated or suspended at any time by
the respective Fund or State Street Bank. Retirement plans and accounts that are
subject to backup withholding are not eligible for the privilege. A "stop
payment" system is not available on these checks. See the Statements of
Additional Information for further information regarding the establishment of
the privilege.
    
 
  AUTOMATED CLEARING HOUSE ("ACH") DEPOSITS. Holders of Class A Shares can use
ACH to have redemption proceeds deposited electronically into their bank
accounts. Redemptions transferred to a bank account via the ACH plan are
available to be credited to the account on the second business day following
normal payment. In order to utilize this option, the shareholder's bank must be
a member of Automated Clearing House. In addition, the shareholder must fill out
the appropriate section of the account application. The shareholder must also
include a voided check or deposit slip from the bank account into which
redemptions are to be deposited together with the completed application. Once
ACCESS has received the application and the voided check or deposit slip, such
shareholder's designated bank account, following any redemption, will be
credited with the proceeds of such redemption. Once enrolled in the ACH plan, a
shareholder may terminate participation at any time by writing ACCESS.
 
- ------------------------------------------------------------------------------
REDEMPTION OF SHARES
- ------------------------------------------------------------------------------
 
  Shareholders may redeem for cash some or all of their shares without charge by
the respective Fund (other than, with respect to CDSC Shares, the applicable
contingent deferred sales charge) at any time by sending a written request in
proper form directly to ACCESS, P. O. Box 418256, Kansas City, Missouri
64141-9256, by placing the redemption request through an authorized dealer or by
calling the respective Fund.
 
  WRITTEN REDEMPTION REQUESTS. In the case of redemption requests sent directly
to ACCESS, the redemption request should indicate the number of shares to be
redeemed, the class designation of such shares, the account number and be signed
exactly as the shares are registered. Signatures must conform exactly to the
account registration. If the proceeds of the redemption would exceed $50,000, or
if the proceeds are not to be paid to the record owner at the record address, or
if the
 
                                       44
<PAGE>   126
 
record address has changed within the previous 30 days, signature(s) must be
guaranteed by one of the following: a bank or trust company; a broker-dealer; a
credit union; a national securities exchange, registered securities association
or clearing agency; a savings and loan association; or a federal savings bank.
If certificates are held for the shares being redeemed, such certificates must
be endorsed for transfer or accompanied by an endorsed stock power and sent with
the redemption request. In the event the redemption is requested by a
corporation, partnership, trust, fiduciary, executor or administrator, and the
name and title of the individual(s) authorizing such redemption is not shown in
the account registration, a copy of the corporate resolution or other legal
documentation appointing the authorized signer and certified within the prior 60
days must accompany the redemption request. The redemption price is the net
asset value per share next determined after the request is received by ACCESS in
proper form. Payment for shares redeemed (less any sales charge, if applicable)
will ordinarily be made by check mailed within three business days after
acceptance by ACCESS of the request and any other necessary documents in proper
order. Such payments may be postponed or the right of redemption suspended as
provided by the rules of the SEC. If the shares to be redeemed have been
recently purchased by check, ACCESS may delay mailing a redemption check until
it confirms that the purchase check has cleared, usually a period of up to 15
days. Any gain or loss realized on the redemption of shares is a taxable event.
 
  DEALER REDEMPTION REQUESTS. Shareholders may sell shares through their
securities dealer, who will telephone the request to the Distributor. Orders
received from dealers must be at least $500 unless transmitted via the FUNDSERV
network. The redemption price for such shares is the net asset value next
calculated after an order is received by a dealer provided such order is
transmitted to the Distributor prior to the Distributor's close of business on
such day. It is the responsibility of dealers to transmit redemption requests
received by them to the Distributor so they will be received prior to such time.
Any change in the redemption price due to failure of the Distributor to receive
a sell order prior to such time must be settled between the shareholder and
dealer. Shareholders must submit a written redemption request in proper form (as
described above under "Written Redemption Requests") to the dealer within three
business days after calling the dealer with the sell order. Payment for shares
redeemed (less any sales charge, if applicable) will ordinarily be made by check
mailed within three business days to the dealer.
 
   
  TELEPHONE REDEMPTION REQUESTS. Each of the Funds permits redemption of shares
by telephone and for redemption proceeds to be sent to the address of record for
the account or to the bank account of record as described below. To establish
such privilege, a shareholder must complete the appropriate section of the
application accompanying this Prospectus or call the respective Fund at (800)
421-5666 ((800) 421-2833 for the hearing impaired) to request that a copy of the
Telephone Redemption Authorization form be sent to them for completion. To
redeem shares, contact the telephone transaction line at (800) 421-5684. VKAC
and the Funds employ procedures considered by them to be reasonable to confirm
that instructions
    
 
                                       45
<PAGE>   127
 
communicated by telephone are genuine. Such procedures include requiring certain
personal identification information prior to acting upon telephone instructions,
tape recording telephone communications, and providing written confirmation of
instructions communicated by telephone. If reasonable procedures are employed, a
shareholder agrees that neither VKAC nor the respective Fund will be liable for
following instructions which it reasonably believes to be genuine. VKAC and the
respective Fund may be liable for any losses due to unauthorized or fraudulent
instructions if reasonable procedures are not followed. Telephone redemptions
may not be available if the shareholder cannot reach ACCESS by telephone,
whether because all telephone lines are busy or for any other reason; in such
case, a shareholder would have to use the respective Fund's other redemption
procedures previously described. Requests received by ACCESS prior to 4:00 p.m.,
New York time, on a regular business day will be processed at the net asset
value per share determined that day. These privileges are available for all
accounts other than retirement accounts. The telephone redemption privilege is
not available for shares represented by certificates. If the shares to be
redeemed have been recently purchased by check, ACCESS may delay mailing a
redemption check or wiring redemption proceeds until it confirms that the
purchase check has cleared, usually a period of up to 15 days. If an account has
multiple owners, ACCESS may rely on the instructions of any one owner.
 
  For redemptions authorized by telephone, amounts of $50,000 or less may be
redeemed daily if the proceeds are to be paid by check sent to the shareholders'
address of record and amounts of at least $1,000 and up to $1 million may be
redeemed daily if the proceeds are to be paid by wire sent to the shareholder's
bank account of record. The proceeds must be payable to the shareholder(s) of
record. Proceeds from redemptions to be paid by check will ordinarily be mailed
within three business days to the shareholder's address of record. Proceeds from
redemptions to be paid by wire will ordinarily be wired on the next business day
to the shareholder's bank account of record. This privilege is not available if
the address of record has been changed within 30 days prior to a telephone
redemption request. Each of the Funds reserves the right at any time to
terminate, limit or otherwise modify this telephone redemption privilege.
 
   
  REDEMPTION UPON DISABILITY. The Funds will waive the CDSC on redemptions
following the disability of holders of Class B Shares and Class C Shares. An
individual will be considered disabled for this purpose if he or she meets the
definition thereof in Section 72(m)(7) of the Code, which in pertinent part
defines a person as disabled if such person "is unable to engage in any
substantial gainful activity by reason of any medically determinable physical or
mental impairment which can be expected to result in death or to be of
long-continued and indefinite duration." While the Funds do not specifically
adopt the balance of the Code's definition which pertains to furnishing the
Secretary of Treasury with such proof as he or she may require, the Distributor
will require satisfactory proof of disability before it determines to waive the
CDSC on Class B Shares and Class C Shares.
    
 
                                       46
<PAGE>   128
 
   
  In cases of disability, the CDSCs on Class B Shares and Class C Shares will be
waived where the disabled person is either an individual shareholder or owns the
shares as a joint tenant with right of survivorship or is the beneficial owner
of a custodial or fiduciary account, and where the redemption is made within one
year of the initial determination of disability. This waiver of the CDSC on
Class B Shares and Class C Shares applies to a total or partial redemption, but
only to redemptions of shares held at the time of the initial determination of
disability.
    
 
   
  GENERAL REDEMPTION INFORMATION. The respective Fund may redeem any shareholder
account with a net asset value on the date of the notice of redemption less than
the minimum investment as specified by the Trustees. At least 60 days advance
written notice of any such involuntary redemption is required and the
shareholder is given an opportunity to purchase the required value of additional
shares at the next determined net asset value without sales charge. Any
applicable CDSC will be deducted from the proceeds of this redemption. Any
involuntary redemption may only occur if the shareholder account is less than
the minimum investment due to shareholder redemptions.
    
 
   
  REINSTATEMENT PRIVILEGE. Holders of Class A Shares or Class B Shares who have
redeemed shares of the respective Fund may reinstate any portion or all of the
net proceeds of such redemption in Class A Shares of such Fund. Holders of Class
C Shares who have redeemed shares of the respective Fund may reinstate any
portion or all of the net proceeds of such redemption in Class C Shares of such
Fund with credit given for any CDSC paid upon such redemption. Such
reinstatement is made at the net asset value (without sales charge except as
described under "Shareholder Services -- Exchange Privilege") next determined
after the order is received, which must be within 180 days after the date of the
redemption. See "Purchase of Shares -- Waiver of Contingent Deferred Sales
Charge." Reinstatement at net asset value is also offered to participants in
those eligible retirement plans held or administered by Van Kampen American
Capital Trust Company for repayment of principal (and interest) on their
borrowings on such plans.
    
 
- ------------------------------------------------------------------------------
   
DISTRIBUTION AND SERVICE PLANS
    
- ------------------------------------------------------------------------------
 
  Each of the Funds has adopted a distribution plan (the "Distribution Plan")
with respect to each class of its shares pursuant to Rule 12b-1 under the 1940
Act. Each of the Funds also has adopted a service plan (the "Service Plan") with
respect to each class of shares. The Distribution Plan and Service Plan of each
Fund provide that the respective Fund may spend a portion of such Fund's average
daily net assets attributable to each class of its shares in connection with the
distribution of respective class of shares and in connection with the provision
of ongoing services to shareholders of each class. Each Distribution Plan and
Service Plan is being implemented through an agreement with the Distributor and
sub-agreements between the Distributor and brokers, dealers and financial
 
                                       47
<PAGE>   129
 
intermediaries (collectively, "Selling Agreements") that may provide for their
customers or clients certain services or assistance.
 
   
  CLASS A SHARES.  Each of the Funds may spend an aggregate amount up to 0.25%
per year of the average daily net assets attributable to the Class A Shares of
the respective Fund pursuant to its Distribution Plan and Service Plan. From
such amount, the respective Fund may spend up to 0.25% per year of the average
daily net assets attributable to its Class A Shares pursuant to its Service Plan
in connection with the ongoing provision of services to holders of such shares
by the Distributor and by brokers, dealers or financial intermediaries and in
connection with the maintenance of such shareholders' accounts. Each of the
Funds pays the Distributor the lesser of the balance of the 0.25% not paid to
such brokers, dealers or financial intermediaries or the amount of the
Distributor's actual distribution-related expense.
    
 
  CLASS B SHARES.  Each of the Funds may spend up to 0.75% per year of the
average daily net assets attributable to the Class B Shares of the respective
Fund pursuant to the Distribution Plan. In addition, each of the Funds may spend
up to 0.25% per year of such Fund's average daily net assets attributable to the
Class B Shares of the respective Fund pursuant to its Service Plan in connection
with the ongoing provision of services to holders of such shares by the
Distributor and by brokers, dealers or financial intermediaries and in
connection with the maintenance of such shareholders' accounts.
 
   
  CLASS C SHARES.  Each of the Funds may spend up to 0.75% per year of the
average daily net assets attributable to the Class C Shares of the respective
Fund pursuant to the Distribution Plan. From such amount, each of the Funds, or
the Distributor as agent for the respective Fund, pays brokers, dealers or
financial intermediaries in connection with the distribution of the Class C
Shares up to 0.75% of the respective Fund's average daily net assets
attributable to Class C Shares maintained in such Fund more than one year by
such broker's, dealer's or financial intermediary's customers. Each of the Funds
pays the Distributor the lesser of the balance of 0.75% not paid to such
brokers, dealers or financial intermediaries or the amount of the Distributor's
actual distribution-related expense. In addition, each of the Funds may spend up
to 0.25% per year of the average daily net assets attributable to the Class C
Shares of the respective Fund pursuant to its Service Plan in connection with
the ongoing provision of services to holders of such shares by the Distributor
and by brokers, dealers or financial intermediaries and in connection with the
maintenance of such shareholders' accounts.
    
 
   
  OTHER INFORMATION.  Amounts payable to the Distributor with respect to the
Class A Shares under the Distribution Plan in a given year may not fully
reimburse the Distributor for its actual distribution-related expenses during
such year. In such event, with respect to the Class A Shares, there is no
carryover of such reimbursement obligations to succeeding years.
    
 
                                       48
<PAGE>   130
 
   
  The Distributor's actual expenses with respect to a class of CDSC Shares (for
purposes of this section, excluding any Class A Shares that may be subject to a
CDSC) for any given year may exceed the amounts payable to the Distributor with
respect to such class of CDSC Shares under the Distribution Plan, the Service
Plan and payments received pursuant to the CDSC. In such event, with respect to
any such class of CDSC Shares, any unreimbursed expenses will be carried forward
and paid by the respective Fund (up to the amount of the actual expenses
incurred) in future years so long as such Distribution Plan is in effect. Except
as mandated by applicable law, the Funds do not impose any limit with respect to
the number of years into the future that such unreimbursed expenses may be
carried forward (on a fund level basis). Because such expenses are accounted on
a fund level basis, in periods of extreme net asset value fluctuation such
amounts with respect to a particular CDSC Share may be greater or less than the
amount of the initial commission (including carrying cost) paid by the
Distributor with respect to such CDSC Share. In such circumstances, a
shareholder of such CDSC Share may be deemed to incur expenses attributable to
other shareholders of such class. As of December 31, 1996, there were $1,243,753
and $12,975 of unreimbursed distribution expenses with respect to Class B Shares
and Class C Shares, respectively of the Insured Fund, representing 1.74% and
less than 0.26% of the Insured Fund's net assets attributable to Class B Shares
and Class C Shares, respectively. As of December 31, 1996, there were $555,803
and $6,908 of unreimbursed distribution expenses with respect to Class B Shares
and Class C Shares, respectively of the California Insured Fund, representing
1.94% and less than 0.31% of the California Insured Fund's net assets
attributable to Class B Shares and Class C Shares, respectively. If the
Distribution Plan was terminated or not continued, the Funds would not be
contractually obligated to pay the Distributor for any expenses not previously
reimbursed by the Fund or recovered through CDSCs.
    
 
   
  Because each of the Funds is a series of the Trust, amounts paid to the
Distributor as reimbursement for expenses of one series of the Trust may
indirectly benefit the other funds which are series of the Trust. The
Distributor will endeavor to allocate such expenses among such funds in an
equitable manner. The Distributor will not use the proceeds from the CDSC
applicable to a particular class of shares to defray distribution-related
expenses attributable to any other class of shares. Various federal and state
laws prohibit national banks and some state-chartered commercial banks from
underwriting or dealing in the Funds' shares. In addition, state securities laws
on this issue may differ from the interpretations of federal law, and banks and
financial institutions may be required to register as dealers pursuant to state
law. In the unlikely event that a court were to find that these laws prevent
such banks from providing such services described above, the Funds would seek
alternate providers and expects that shareholders would not experience any
disadvantage.

- ------------------------------------------------------------------------------
DISTRIBUTIONS FROM THE FUNDS
- ------------------------------------------------------------------------------
 
  Each Fund's policy is to declare daily and pay monthly distributions of all or
substantially all net investment income of such Fund. Each Fund's net recognized
investment income consists of all of its respective interest income, dividends
and other ordinary income earned by such Fund on its portfolio assets, less all
expenses of such Fund. Expenses of the Funds are accrued each day. Net long- and
short-term capital gains, if any, are expected to be distributed, to the extent
permitted by applicable law, to shareholders at least annually. Distributions
cannot be assured, and the amount of each monthly distribution may vary.
 
  Distributions with respect to each class of shares will be calculated in the
same manner on the same day and will be in the same amount, except that the
different distribution and service fees and any incremental administrative
expenses relating to each class of shares will be borne exclusively by the
respective class and may cause the distributions relating to the different
classes of shares to differ. Generally, distributions with respect to a class of
shares subject to a higher distribution fee, service fee, or, where applicable,
the conversion feature will be lower than distributions with respect to a class
of shares subject to a lower distribution fee, service fee, or not subject to
the conversion feature.
 
   
  Investors will be entitled to begin receiving dividends on their shares on the
business day after ACCESS receives payments for such shares. However, shares
become entitled to dividends on the day ACCESS receives payment for the shares
either through a fed wire or NSCC settlement. Shares remain entitled to
dividends through the day such shares are processed for payment on redemption.
    
 
  Distribution checks may be sent to parties other than the shareholder in whose
name the account is registered. Persons wishing to utilize this service should
complete the appropriate section of the account application accompanying this
Prospectus or available from Van Kampen American Capital Funds, c/o ACCESS, P.O.
Box 418256, Kansas City, MO 64141-9256. After ACCESS receives this completed
form, distribution checks will be sent to the bank or other person so designated
by such shareholder.
 
   
  PURCHASE OF ADDITIONAL SHARES WITH DISTRIBUTIONS.  Each Fund will
automatically credit dividend distributions and any net long-term capital gain
distributions to a shareholder's account in additional shares of the respective
Fund valued at net asset value, without a sales charge. Unless a shareholder
instructs otherwise, the reinvestment plan is automatic. This instruction may be
made by telephone by calling (800) 421-5666 ((800) 421-2833 for the hearing
impaired) or in writing to ACCESS. See "Shareholder Services -- Reinvestment
Plan."

- ------------------------------------------------------------------------------
TAX STATUS
- ------------------------------------------------------------------------------
 
   
  FEDERAL INCOME TAXATION.  The Funds have qualified and intend to continue to
qualify each year and to elect to be treated as a regulated investment companies
under Subchapter M of the Code. To qualify as a regulated investment company,
the Funds must comply with certain requirements of the Code relating to, among
other things, the source of its income and diversification of its assets.
    
 
   
  If the Funds so qualify and distribute each year to their respective
shareholders at least 90% of its net investment income (including tax-exempt
interest, taxable income and net short-term capital gain, but not net capital
gains, which are the excess of net long-term capital gains over net short-term
capital losses), they will not be required to pay federal income taxes on any
income distributed to shareholders. The Funds intend to distribute at least the
minimum amount of net investment income necessary to satisfy the 90%
distribution requirement. The Funds will not be subject to federal income tax on
any net capital gains distributed to shareholders.
    
 
   
  In order to avoid a 4% excise tax, the Funds will be required to distribute,
by December 31 of each year, at least 98% of its ordinary income (not including
tax-exempt income) for such year and at least 98% of its capital gain net income
(the latter of which generally is computed on the basis of the one-year period
ending on October 31 of such year), plus any amounts that were not distributed
in previous taxable years. For purposes of the excise tax, any ordinary income
or capital gain net income retained by, and subject to federal income tax in the
hands of, the Funds will be treated as having been distributed.
    
 
   
  If either Fund failed to qualify as a regulated investment company or failed
to satisfy the 90% distribution requirement in any taxable year, such Fund would
be taxed as an ordinary corporation on its taxable income (even if such income
were distributed to its shareholders) and all distributions out of earnings and
profits would be taxed to shareholders as ordinary income. To qualify again as a
regulated investment company in a subsequent year, a Fund may be required to pay
an interest charge on 50% of its earnings and profits attributable to
non-regulated investment company years and would be required to distribute such
earnings and profits to shareholders (less any interest charge). In addition, if
a Fund failed to qualify as a regulated investment company for its first taxable
year or, if immediately after qualifying as a regulated investment company for
any taxable year, it failed to qualify for a period greater than one taxable
year, such Fund would be required to recognize any net built-in gains (the
excess of aggregate gains, including items of income, over aggregate losses that
would have been realized if it had been liquidated) in order to qualify as a
regulated investment company in a subsequent year.
    
 
   
  Certain of each Fund's investment practices are subject to special provisions
of the Code that, among other things, may defer the use of certain losses of
such Fund and affect the holding period of the securities held by such Fund and
the character
    
 
                                       51
<PAGE>   133
 
   
of the gains or losses realized by the Fund. These provisions may also require
each Fund to mark-to-market some of the positions in its portfolio (i.e., treat
them as if they were sold for fair market value at the end of the tax-year),
which may cause such Fund to recognize income without receiving cash with which
to make distributions in amounts necessary to satisfy the 90% distribution
requirement and the distribution requirements for avoiding income and excise
taxes. The Funds will monitor their transactions and may make certain tax
elections in order to mitigate the effect of these rules and prevent
disqualification of the Funds as a regulated investment companies.
    
 
   
  Each Fund's ability to dispose of portfolio securities may be limited by the
requirement for qualification as a regulated investment company that less than
30% of the Fund's annual gross income be derived from the disposition of
securities held for less than three months.
    
 
   
  Investments of the Funds in securities issued at a discount or providing for
deferred interest or payment of interest in kind are subject to special tax
rules that will affect the amount, timing and character of distributions to
shareholders. For example, with respect to securities issued at a discount, the
Funds will be required to accrue as income each year a portion of the discount
and to distribute such income each year in order to maintain its qualification
as a regulated investment company and to avoid income and excise taxes. In order
to generate sufficient cash to make distributions necessary to satisfy the 90%
distribution requirement and to avoid income and excise taxes, the Funds may
have to dispose of securities that it would otherwise have continued to hold. A
portion of the discount relating to certain stripped tax-exempt obligations may
constitute taxable income when distributed to shareholders.
    
 
   
  DISTRIBUTIONS.  The Funds intend to invest in sufficient tax-exempt municipal
securities to permit payment of "exempt-interest dividends" (as defined in the
Code). Dividends paid by the Funds from the net tax-exempt interest earned from
municipal securities qualify as exempt-interest dividends if, at the close of
each quarter of its taxable year, at least 50% of the value of the total assets
of each respective Fund consists of municipal securities.
    
 
   
  The Tax Reform Act of 1986 (the "Tax Reform Act") may have an adverse impact
upon the Funds and their shareholders. The Tax Reform Act imposed new
limitations on the use and investment of the proceeds of state and local
government bonds and other funds, which limitations must be satisfied in order
to maintain the exclusion from gross income for interest on such bonds. The
provisions of the Tax Reform Act generally apply to bonds issued after August
15, 1986. In light of these requirements, bond counsel qualify their opinions as
to the federal tax status of bonds issued after August 15, 1986 by making them
contingent on the issuer's future compliance with these limitations. Any failure
on the part of an issuer to comply could cause the interest on its bonds to
become taxable to investors retroactive to the date the bonds were issued.
    
 
                                       52
<PAGE>   134
 
   
  Except as provided below, exempt-interest dividends paid to shareholders
generally are not includable in the shareholders' gross income for federal
income tax purposes. The percentage of the total dividends paid by a Fund during
any taxable year that qualify as exempt-interest dividends will be the same for
all shareholders of such Fund receiving dividends during such year.
    
 
   
  The Tax Reform Act also makes interest on certain "private-activity bonds" an
item of tax preference subject to the alternative minimum tax on individuals and
corporations. The Funds invest a portion of their assets in municipal securities
subject to this provision so that a portion of its exempt-interest dividends is
an item of tax preference to the extent such dividends represent interest
received from these private-activity bonds. Accordingly, investment in either
Fund could cause shareholders to be subject to (or result in an increased
liability under) the alternative minimum tax. The Tax Reform Act also imposed
per capita volume limitations on certain private-activity bonds which could
limit the amount of such bonds available for investment by the Funds.
    
 
   
  Exempt-interest dividends are included in determining what portion, if any, of
a person's social security and railroad retirement benefits will be includable
in gross income subject to federal income tax.
    
 
   
  Although exempt-interest dividends generally may be treated by shareholders as
items of interest excluded from their gross income, each shareholder is advised
to consult his tax adviser with respect to whether exempt-interest dividends
retain this exclusion if the purchaser would be treated as a "substantial user"
(or a "related person" of a substantial user) of the facilities financed with
respect to any of the tax-exempt obligations held by either Fund, or by the
Trust if it is required to qualify as a regulated investment company as
described below. "Substantial user" is defined under U.S. Treasury Regulations
to include a non-exempt person who regularly uses in his trade or business a
part of any facilities financed with the tax-exempt obligations and whose gross
revenues derived from such facilities exceed 5% of the total revenues derived
from the facilities by all users, or who occupies more than 5% of the useable
area of the facilities or for whom the facilities or a part thereof were
specifically constructed, reconstructed or acquired. Examples of "related
persons" include certain related natural persons, affiliated corporations, a
partnership and its partners and an S corporation and its shareholders.
    
 
   
  The Omnibus Budget Reconciliation Act of 1993 included certain provisions that
requires gains on dispositions of tax-exempt securities purchased at a market
discount be treated as ordinary income to the extent of the accrued market
discount, if the securities are acquired after April 30, 1993. Such securities
were exempt from the market discount rules under prior law. Interest on
indebtedness incurred or continued by a shareholder to purchase or carry shares
of either Fund is not deductible for federal income tax purposes if such Fund
distributes exempt-interest dividends during the shareholder's taxable year. If
a shareholder receives an exempt-interest dividend with respect to any shares
and such shares are held for six months or less, any
    
 
                                       53
<PAGE>   135
 
   
short-term capital loss on the sale or exchange of the shares will be disallowed
to the extent of the amount of such exempt-interest dividend.
    
 
   
  While the Funds expect that a major portion of their net investment income
will constitute tax-exempt interest, a significant portion may consist of
investment company taxable income. Distributions of each Fund's net investment
company taxable income are taxable to shareholders as ordinary income to the
extent of such Fund's earnings and profits, whether paid in cash or reinvested
in additional shares. Distributions of each Fund's net capital gains ("capital
gains dividends"), if any, are taxable to shareholders as long-term capital
gains regardless of the length of time shares of such Fund have been held by
such shareholders. Interest on indebtedness which is incurred to purchase or
carry shares of a mutual fund which distributes exempt-interest dividends during
the year is not deductible for federal income tax purposes. Distributions in
excess of each Fund's earnings and profits will first reduce the adjusted tax
basis of a holder's shares and, after such adjusted tax basis is reduced to
zero, will constitute capital gains to such holder (assuming such shares are
held as a capital asset). Tax-exempt shareholders not subject to federal income
tax on their income generally will not be taxed on distributions from the Funds.
    
 
   
  Shareholders receiving distributions in the form of additional shares issued
by the Funds will be treated for federal income tax purposes as receiving a
distribution in an amount equal to the fair market value of the shares received,
determined as of the distribution date. The basis of such shares will equal the
fair market value on the distribution date.
    
 
   
  The Funds will inform shareholders of the source and tax status of all
distributions promptly after the close of each calendar year. The aggregate
amount of dividends so designated cannot exceed, however, the amount of interest
exempt from tax under Section 103 of the Code received by either Fund during the
year over any amounts disallowed as deductions under Sections 265 and 171(a)(2)
of the Code. Since the percentage of dividends which are "exempt-interest"
dividends is determined on an average annual method for the fiscal year, the
percentage of income designated as tax-exempt for any particular dividend may be
substantially different from the percentage of each Fund's income that was tax
exempt during the period covered by the dividend, Fund distributions generally
will not qualify for the dividends received deduction for corporations.
    
 
   
  Although dividends generally will be treated as distributed when paid,
dividends declared in October, November or December, payable to shareholders of
record on a specified date in such month and paid during January of the
following year will be treated as having been distributed by the Funds and
received by the shareholders on the December 31 prior to the date of payment. In
addition, certain other distributions made after the close of a taxable year of
each Fund may be "spilled back" and treated as paid by such Fund (except for
purposes of the 4% excise tax) during such taxable year. In such case,
shareholders will be treated as having received such dividends in the taxable
year in which the distribution was actually made.
    
 
                                       54
<PAGE>   136
 
   
  The Funds are required, in certain circumstances, to withhold 31% of dividends
and certain other payments, including redemptions, paid to shareholders who do
not furnish to the Funds their correct taxpayer identification number (in the
case of individuals, their social security number) and certain required
certifications or who are otherwise subject to backup withholding.
    
 
   
  SALE OF SHARES.  The sale of shares (including transfers in connection with a
redemption or repurchase of shares) will be a taxable transaction for federal
income tax purposes. Selling shareholders will generally recognize gain or loss
in an amount equal to the difference between their adjusted tax basis in the
shares and the amount received. If such shares are held as a capital asset, the
gain or loss will be a capital gain or loss and will be long-term if such shares
have been held for more than one year. Any loss realized upon a taxable
disposition of shares held for six months or less will be treated as a long-term
capital loss to the extent of any capital gains dividends received with respect
to such shares. For purposes of determining whether shares have been held for
six months or less, the holding period is suspended for any periods during which
the shareholder's risk of loss is diminished as a result of holding one or more
other positions in substantially similar or related property or through certain
options or short sales.
    
 
   
  CALIFORNIA TAX STATUS. Under existing California income tax law, if at the
close of each quarter of the California Insured Fund's taxable year at least 50%
of the value of its total assets consists of obligations of the State of
California and its political subdivisions, shareholders of the California
Insured Fund who are subject to the California personal income tax will not be
subject to such tax on distributions with respect to their shares of the
California Insured Fund to the extent that such distributions are attributable
to such tax-exempt interest from such obligations (less expenses applicable
thereto). If such distributions are received by a corporation subject to the
California franchise tax, however, the distributions will be includable in its
gross income for purposes of determining its California franchise tax.
Corporations subject to the California corporate income tax may be subject to
such taxes with respect to distributions from the California Insured Fund.
Accordingly, an investment in shares of the California Insured Fund may not be
appropriate for corporations subject to either tax. Under California personal
property tax law, securities owned by the California Insured Fund and any
interest thereon are exempt from such personal property tax. Any proceeds paid
to the California Insured Fund under the insurance policy which represents
matured interest on defaulted obligations should be exempt from California
personal income tax if, and to the same extent as, such interest would have been
exempt if paid by the issuer of such defaulted obligations. Recent amendments to
California tax laws substantially incorporate those provisions of the Code
governing the treatment of regulated investment companies.
    
 
  GENERAL. The federal and California income tax discussions set forth above are

FUND PERFORMANCE
- ------------------------------------------------------------------------------
 
   
  From time to time advertisements and other sales materials for each respective
Fund may include information concerning the historical performance of such Fund.
Any such information will include the average total return of such Fund
calculated on a compounded basis for specified periods of time. Such
advertisements and sales material may also include a yield quotation as of a
current period. In each case, such total return and yield information, if any,
will be calculated pursuant to rules established by the SEC and will be computed
separately for each class of a Fund's shares. In lieu of or in addition to total
return and yield calculations, such information may include performance rankings
and similar information from independent organizations such as Lipper Analytical
Services, Inc. or nationally recognized financial publications.
    
 
  The yield quotations are determined for each class of a Fund's shares on a
monthly basis with respect to the immediately preceding 30 day period. Yield is
computed by dividing the respective Fund's net investment income per share
earned during such 30 day period by such Fund's maximum offering price per share
on the last day of such period. Net investment income per share for a class of
shares is determined by taking the interest earned by the respective Fund during
the period and allocable to the class of shares, subtracting the expenses (net
of reimbursements) accrued for the period and allocable to the class of shares,
and dividing the result by the product of (a) the average daily number of such
class of shares of the respective Fund outstanding during the period that were
entitled to receive dividends and (b) such Fund's maximum offering price per
share on the last day of the period. The yield calculation formula assumes net
investment income is earned and reinvested at a constant rate and annualized at
the end of a six month period.
 
  Tax-equivalent yield demonstrates the taxable yield required to produce an
after-tax yield equivalent to that of a Fund's yield. A tax-equivalent yield
quotation for a 30 day period as described above is computed for each class of a
Fund's shares by dividing that portion of the yield of such Fund (as computed
above) which is tax-exempt by a percentage equal to 100% minus a stated
percentage income tax rate and adding the result to that portion of such Fund's
yield, if any, that is not tax-exempt.
 
  The average compounded total return for each class of a Fund's shares is
calculated by determining the redemption value at the end of specified periods
(after adding back all dividends and other distributions made during the period)
of a $1,000 investment in a class of shares of such Fund (less the maximum sales
charge) at the beginning of the period, annualizing the increase or decrease
over the specified period with respect to such initial investment and expressing
the result as a percentage.
 
                                       56
<PAGE>   138
 
  Total return figures utilized by each Fund are based on historical performance
and are not intended to indicate future performance. Total return and net asset
value per share can be expected to fluctuate over time, and accordingly upon
redemption a shareholder's shares may be worth more or less than their original
cost.
 
  Each of the Funds may, in supplemental sales literature, advertise
non-standardized total return figures representing the cumulative,
non-annualized total return of such Fund from a given date to a subsequent given
date. Cumulative non-standardized total return is calculated by measuring the
value of an initial investment in such Fund at a given time, including or
excluding any applicable sales charge as indicated, deducting the respective
Fund's maximum sales charge, determining the value of all subsequent reinvested
distributions, and dividing the net change in the value of the investment as of
the end of the period by the amount of the initial investment and expressing the
result as a percentage.
 
   
  From time to time either Fund may include in its supplemental sales literature
and shareholder reports a quotation of the current "distribution rate" for the
respective Fund. Distribution rate is a measure of the level of income and
short-term capital gain dividends, if any, distributed for a specified period.
Distribution rate is determined by annualizing the distributions per share for a
stated period and dividing the result by the public offering price for the same
period. It differs from yield, which is a measure of the income actually earned
by a Fund's investments, and from total return, which is a measure of the income
actually earned by, plus the effect of any realized and unrealized appreciation
or depreciation of such investments during a stated period. Distribution rate
is, therefore, not intended to be a complete measure of a Fund's performance.
Distribution rate may sometimes be greater than yield since, for instance, it
may not include the effect of amortization of bond premiums, and may include
non-recurring short-term capital gains and premiums from futures transactions
engaged in by a Fund. Distribution rates will be calculated separately for each
class of a Fund's shares.
    
 
  From time to time, a Fund may compare its performance to certain securities
and unmanaged indices which may have different risk/reward characteristics than
the Fund. Such characteristics may include, but are not limited to, tax
features, guarantees, insurance and the fluctuation of principal and/or return.
In addition, from time to time, a Fund may utilize sales literature that
includes hypotheticals.

its Annual Report and its Statement of Additional Information each of which can

  This Prospectus and the Statement of Additional Information do not contain all
the information set forth in the Registration Statement filed by the Fund with
the SEC under the Securities Act of 1933. Copies of the Registration Statement
may be obtained at a reasonable charge from the SEC or may be examined, without
charge, at the office of the SEC in Washington, D.C.
 
  Shareholders will receive annual and semiannual reports with financial
statements, as well as proxy statements for shareholders' meetings, if any. Each
Fund is a separate series of the Trust, a Delaware business trust. The Insured
Fund was originally organized as a Maryland corporation under the name Van
Kampen Merritt Insured Tax Free Fund Inc., was subsequently reorganized into a
sub-trust of Van Kampen Merritt Tax Free Fund, a Massachusetts business trust,
under the name Van Kampen Merritt Insured Tax Free Income Fund as of February
22, 1988 and was again reorganized as a series of the Trust on July 31, 1995.
The California Insured Fund was organized under the name Van Kampen Merritt
California Insured Tax Free Fund as a sub-trust of Van Kampen Merritt Tax Free
Fund and was reorganized as a series of the Trust on July 31, 1995. Shares of
the Trust entitle their holders to one vote per share; however, separate votes
are taken by each series on matters affecting an individual series. The Trust
does not contemplate holding regular meetings of shareholders to elect Trustees
or otherwise. However, the holders of 10% or more of the outstanding shares may
by written request require a meeting to consider the removal of Trustees by a
vote of two-thirds of the shares then outstanding cast in person or by proxy at
such meeting. The Trust will assist such holders in communicating with other
shareholders of the Funds to the extent required by the 1940 Act. More detailed
information concerning the Trust is set forth in the Statement of Additional
Information of each Fund.
 
  Each Fund's fiscal year end is December 31. Each of the Funds send to their
shareholders, at least semi-annually, reports showing the respective Fund's
portfolio and other information. An annual report, containing financial
statements audited by independent public accountants, is sent to shareholders
each year. After the end of each year, shareholders will receive federal income
tax information regarding dividends and capital gains distributions.
 
  Shareholder inquiries should be directed to the Van Kampen American Capital
Insured Tax Free Income Fund or Van Kampen American Capital California Insured
Tax Free Fund, as applicable, One Parkview Plaza, Oakbrook Terrace, Illinois

                               PROSPECTUS SUMMARY
- ------------------------------------------------------------------------------
 
THE FUND.  Van Kampen American Capital Municipal Income Fund (the "Fund") is a
separate diversified series of Van Kampen American Capital Tax Free Trust (the
"Trust"), an open-end management investment company organized as a Delaware
business trust. See "The Fund."
 
MINIMUM PURCHASE.  $500 minimum initial investment for each class of shares and
$25 minimum subsequent investment for each class of shares (or less as described
under "Purchase of Shares").
 
INVESTMENT OBJECTIVE.  The Fund's investment objective is to provide investors
with a high level of current income exempt from federal income tax, consistent
with preservation of capital.
 
INVESTMENT POLICY.  The Fund seeks to achieve its investment objective by
investing at least 80% of its assets in a diversified portfolio of tax-exempt
municipal securities rated investment grade at the time of investment.
Investment grade securities are securities rated BBB or higher by Standard &
Poor's Ratings Group ("S&P") or Baa or higher by Moody's Investors Service, Inc.
("Moody's") in the case of long-term obligations, and have equivalent ratings in
the case of short-term obligations. Up to 20% of the Fund's total assets may be
invested in tax-exempt municipal securities rated, at the time of investment,
between BB and B-(inclusive) by S&P or between Ba and B3 (inclusive) by Moody's
(or equivalently rated short-term obligations) and unrated tax-exempt municipal
securities that the Fund's investment adviser believes are of comparable
quality. See "Special Considerations Regarding the Fund."
 
  Municipal securities in which the Fund may invest include fixed and variable
rate securities, municipal notes, municipal leases, tax exempt commercial paper,
custodial receipts, participation certificates and derivative municipal
securities the terms of which include elements of, or are similar in effect to,
certain Strategic Transactions (as defined herein) in which the Fund may engage.
The Fund may invest up to 15% of its total assets in derivative variable rate
securities such as inverse floaters, whose rates vary inversely with changes in
market rates of interest or range or capped floaters, whose rates are subject to
periodic of lifetime caps. There is no assurance that the Fund will achieve its
investment objective. Debt securities rated below investment grade are commonly
referred to as "junk bonds." The net asset value per share of the Fund may
increase or decrease depending on changes in interest rates and other factors
affecting the municipal credit markets. See "Investment Objective and Policies."
 
INVESTMENT PRACTICES.  The Fund also may use various investment techniques
including engaging in risk management transactions and entering into when-issued
or delayed delivery transactions and various strategic transactions. Such
transactions entail certain risks. See "Municipal Securities" and "Investment
Practices." The Fund may invest a substantial portion of its assets in municipal
securities that
 
                                        3
<PAGE>   145
 
pay interest that is subject to the federal alternative minimum tax. The Fund
may not be a suitable investment for investors who are already subject to the
federal alternative minimum tax or who would become subject to the federal
alternative minimum tax as a result of an investment in the Fund. See "Tax
Status."
 
INVESTMENT RESULTS.  The investment results of the Fund are shown in the table
of "Financial Highlights."
 
ALTERNATIVE SALES ARRANGEMENTS.  The Alternative Sales Arrangements permit an
investor to choose the method of purchasing shares that is more beneficial to
the investor, taking into account the amount of the purchase, the length of time
the investor expects to hold the shares and other circumstances. Investors
should consider such factors together with the amount of sales charges and
accumulated distribution and service fees with respect to each class of shares
that may be incurred over the anticipated duration of their investment in the
Fund. To assist investors in making this determination, the table under the
caption "Annual Fund Operating Expenses and Example" sets forth examples of the
charges applicable to each class of shares.
 
  The Fund offers three classes of its shares which may be purchased at a price
equal to their net asset value per share plus sales charges which, at the
election of the investor, may be imposed either (i) at the time of purchase
("Class A Shares") or (ii) on a contingent deferred basis (Class A Share
accounts over $1 million, "Class B Shares," and "Class C Shares"). Class A Share
accounts over $1 million or otherwise subject to a contingent deferred sales
charge ("CDSC"), Class B Shares, and Class C Shares sometimes are referred to
herein collectively as "CDSC Shares."
 
  Class A Shares. Class A Shares are subject to an initial sales charge equal to
4.75% of the public offering price (4.99% of the net amount invested), reduced
on investments of $100,000 or more. Class A Shares are subject to ongoing
distribution and service fees at an aggregate annual rate of up to 0.25% of the
Fund's average daily net assets attributable to the Class A Shares. Certain
purchases of Class A Shares qualify for reduced or no initial sales charges and
may be subject to a CDSC.
 
   
  Class B Shares. Class B Shares do not incur a sales charge when they are
purchased, but are subject to a sales charge if redeemed within six years of
purchase. Class B Shares are subject to a CDSC equal to 4.00% of the lesser of
the then current net asset value or the original purchase price on Class B
Shares redeemed during the first year after purchase, which charge is reduced
each year thereafter. Class B Shares are subject to ongoing distribution and
service fees at an aggregate annual rate of up to 1.00% of the Fund's average
daily net assets attributable to the Class B Shares. Class B Shares
automatically convert to Class A Shares eight years after the end of the
calendar month in which the investor's order to purchase was accepted, in the
circumstances and subject to the qualifications described in this Prospectus.

  Class C Shares. Class C Shares do not incur a sales charge when they are
purchased, but are subject to a sales charge if redeemed within the first year
after purchase. Class C Shares are subject to a CDSC equal to 1.00% of the
lesser of the then current net asset value or the original purchase price on
Class C Shares redeemed within the first year after purchase. Class C Shares are
subject to ongoing distribution and service fees at an aggregate annual rate of
up to 1.00% of the Fund's aggregate average daily net assets attributable to the
Class C Shares.
    
 
REDEMPTION.  Class A Shares may be redeemed at net asset value, without charge,
subject to conditions set forth herein. CDSC Shares may be redeemed at net asset
value less a deferred sales charge which will vary among each class of CDSC
Shares and with the length of time a redeeming shareholder has owned such
shares. CDSC Shares redeemed after the expiration of the CDSC period applicable
to the respective class of CDSC Shares will not be subject to a deferred sales
charge. See "Redemption of Shares."
 
   
INVESTMENT ADVISER.  Van Kampen American Capital Investment Advisory Corp. (the
"Adviser") is the Fund's investment adviser.
    
 
   
DISTRIBUTOR.  Van Kampen American Capital Distributors, Inc. (the "Distributor")
distributes the Fund's shares.
    
 
DISTRIBUTIONS FROM THE FUND.  Distributions from net investment income are
declared daily and paid monthly; net realized capital gains, if any, are
distributed annually. Distributions with respect to each class of shares will be
calculated in the same manner on the same day and will be in the same amount
except that the different distribution and service fees and administrative
expenses relating to each class of shares will be borne exclusively by the
respective class of shares. See "Distributions from the Fund."
 
   
  The foregoing is qualified in its entirety by reference to the more detailed
    
              information appearing elsewhere in this Prospectus.

  The purpose of the foregoing table is to assist an investor in understanding
the various costs and expenses that an investor in the Fund will bear directly
or indirectly. The "Example" reflects expenses based on the "Annual Fund
Operating Expenses" table as shown above carried out to future years. The ten
year amount with respect to Class B Shares of the Fund reflects the lower
aggregate 12b-1 and service fees applicable to such shares after conversion of
Class A Shares. THE INFORMATION CONTAINED IN THE ABOVE TABLE SHOULD NOT BE
CONSIDERED A REPRESENTATION OF PAST OR FUTURE EXPENSES AND ACTUAL EXPENSES MAY
BE GREATER OR LESSER THAN THOSE SHOWN. For a more complete description of such
costs and expenses, see "Purchase of Shares," "Redemption of Shares,"

THE FUND
- ------------------------------------------------------------------------------
 
  Van Kampen American Capital Municipal Income Fund (the "Fund") is a separate
diversified series of Van Kampen American Capital Tax Free Trust (the "Trust"),
which is an open-end management investment company, commonly known as a "mutual
fund," organized as a Delaware business trust. Mutual funds sell their shares to
investors and invest the proceeds in a portfolio of securities. A mutual fund
allows investors to pool their money with that of other investors in order to
obtain professional investment management. Mutual funds generally make it
possible for investors to obtain greater diversification of their investments
and to simplify their recordkeeping.
 
  Van Kampen American Capital Investment Advisory Corp. (the "Adviser") provides
investment advisory and administrative services to the Fund. The Adviser and its
affiliates also manage other mutual funds distributed by Van Kampen American
Capital Distributors, Inc. (the "Distributor"). To obtain prospectuses and other
information on any of these other funds, please call the telephone number on the
cover page of the Prospectus.
 
- ------------------------------------------------------------------------------
INVESTMENT OBJECTIVE AND POLICIES
- ------------------------------------------------------------------------------
 
  The investment objective of the Fund is to provide investors with a high level
of current income exempt from federal income tax, consistent with preservation
of capital. The Fund's investment objective is a fundamental policy and may not
be changed without shareholder approval. Under normal market conditions, the
Fund invests at least 80% of its total assets in tax-exempt municipal securities
rated investment grade. The Fund's policy with respect to ratings is not a
fundamental policy, and thus may be changed by the Trustees without shareholder
approval. See "Municipal Securities." The Fund intends, however, to maintain at
all times at least 80% of its total assets in tax-exempt municipal securities
rated investment grade or deemed by the investment adviser to be of comparable
quality at the time of investment. Investment grade securities are securities
rated BBB or higher by Standard & Poor's Ratings Group ("S&P") or Baa or higher
by Moody's Investors Service, Inc. ("Moody's") in the case of long-term
obligations, and have equivalent ratings in the case of short-term obligations.
According to published guidelines, securities rated BBB by S&P are regarded by
S&P as having an adequate capacity to pay interest and repay principal. Whereas
such securities normally exhibit adequate protection parameters, adverse
economic conditions or changing circumstances are more likely, in the opinion of
S&P, to lead to a weakened capacity to pay interest and repay principal for debt
in this category than in higher rated categories. According to published
guidelines, securities rated Baa by Moody's are considered by Moody's as medium
grade obligations. Such securities are, in the opinion of Moody's, neither
highly protected nor poorly secured. Interest payments and principal security
appear to Moody's to be adequate for the present but certain
 
                                       11
<PAGE>   153
 
protective elements may be lacking or may be characteristically unreliable over
any great length of time. In the opinion of Moody's they lack outstanding
investment characteristics and in fact have speculative characteristics as well.
 
  Up to 20% of the Fund's total assets may be invested in tax-exempt municipal
securities rated, at the time of investment, between BB and B- (inclusive) by
S&P or between Ba and B3 (inclusive) by Moody's (or equivalently rated
short-term obligations) and unrated tax-exempt securities that the Adviser
considers to be comparable quality. These securities are below investment grade
and are regarded by S&P, on balance, as predominantly speculative with respect
to capacity to pay interest and repay principal in accordance with the terms of
the obligation. While in the opinion of S&P such securities will likely have
some quality and protective characteristics, these are outweighed by large
uncertainties or major risk exposures to adverse conditions. These securities
are regarded by Moody's as generally lacking characteristics of a desirable
investment. Assurance of interest and principal payments or of maintenance of
other terms of the securities' contract over any long period of time may, in the
opinion of Moody's, be small. Debt securities rated below investment grade are
commonly referred to as "junk bonds." For a description of S&P's and Moody's
ratings see the Statement of Additional Information. From time to time the Fund
temporarily may also invest up to 10% of its assets in tax exempt money market
funds. Such instruments will be treated as investments in municipal securities.
 
  An investment in the Fund may not be appropriate for all investors. The Fund
is not intended to be a complete investment program, and investors should
consider their long-term investment goals and financial needs when making an
investment decision with respect to the Fund. An investment in the Fund is
intended to be a long-term investment and should not be used as a trading
vehicle.

MUNICIPAL SECURITIES
- ------------------------------------------------------------------------------
 
  GENERAL. Tax-exempt municipal securities are debt obligations issued by or on
behalf of the governments of states, territories or possessions of the United
States, the District of Columbia and their political subdivisions, agencies and
instrumentalities, certain interstate agencies and certain territories of the
United States, the interest on which, in the opinion of bond counsel or other
counsel to the issuer of such securities, is exempt from federal income tax.
Under normal market conditions, up to 100% but not less than 80%, of the Fund's
assets will be invested in municipal securities. The foregoing is a fundamental
policy of the Fund and cannot be changed without approval of the shareholders of
the Fund.
 
  The two principal classifications of municipal securities are "general
obligation" and "revenue" securities. "General obligation" securities are
secured by the issuer's pledge of its faith, credit and taxing power for the
payment of principal and interest. "Revenue" securities are usually payable only
from the revenues derived from a particular facility or class of facilities or,
in some cases, from the proceeds of a
 
                                       12
<PAGE>   154
 
special excise tax or other specific revenue source. Industrial development
bonds are usually revenue securities, the credit quality of which is normally
directly related to the credit standing of the industrial user involved.
 
  Within these principal classifications of municipal securities there are a
variety of categories of municipal securities, including fixed and variable rate
securities, municipal bonds, municipal notes, municipal leases, custodial
receipts, participation certificates and derivative municipal securities the
terms of which include elements of, or are similar in effect to, certain
Strategic Transactions (as defined below) in which the Fund may engage. Variable
rate securities bear rates of interest that are adjusted periodically according
to formulae intended to reflect market rates of interest and include securities
whose rates vary inversely with changes in market rates of interest. The Fund
will not invest more than 15% of its total assets in derivative municipal
securities such as inverse floaters, whose rates vary inversely with changes in
market rates of interest or range floaters or capped floaters whose rates are
subject to periodic or lifetime caps. Such securities may also pay a rate of
interest determined by applying a multiple to the variable rate. The extent of
increases and decreases in the value of securities whose rates vary inversely
with market rates of interest generally will be larger than comparable changes
in the value of such municipal securities generally will fluctuate in response
to changes in market rates of interest to a greater extent than the value of an
equal principal amount of a fixed rate municipal security having similar credit
quality, redemption provisions and maturity. Municipal notes include tax,
revenue and bond anticipation notes of short maturity, generally less than three
years, which are issued to obtain temporary funds for various public purposes.
Municipal leases are obligations issued by state and local governments or
authorities to finance the acquisition of equipment and facilities. Certain
municipal lease obligations may include "non-appropriation" clauses which
provide that the municipality has no obligation to make lease or installment
purchase payments in future years unless money is appropriated for such purpose
on a yearly basis. Custodial receipts are underwritten by securities dealers or
banks and evidence ownership of future interest payments, principal payments or
both on certain municipal securities. Participation certificates are obligations
issued by state or local governments or authorities to finance the acquisition
of equipment and facilities. They may represent participations in a lease, an
installment purchase contract, or a conditional sales contract. Some municipal
securities may not be backed by the faith, credit and taxing power of the
issuer. Certain of the municipal securities in which the Fund may invest
represent relatively recent innovations in the municipal securities markets.
While markets for such recent innovations progress through stages of
development, such markets may be less developed than more fully developed
markets for municipal securities. A more detailed description of the types of
municipal securities in which the Fund may invest is included in the Statement
of Additional Information.
 
  The net asset value of the Fund will change with changes in the value of its
portfolio securities. Because the Fund will invest primarily in fixed income
municipal securities, the net asset value of the Fund can be expected to change
as general
 
                                       13
<PAGE>   155
 
levels of interest rates fluctuate. When interest rates decline, the value of a
portfolio invested in fixed income securities generally can be expected to rise.
Conversely, when interest rates rise, the value of a portfolio invested in fixed
income securities generally can be expected to decline. Volatility may be
greater during periods of general economic uncertainty.
 
  From time to time, proposals have been introduced before Congress that would
have the effect of reducing or eliminating the federal tax exemption on
municipal securities. If such a proposal were enacted, the ability of the Fund
to pay tax exempt interest dividends might be adversely affected.
 
  LOWER GRADE MUNICIPAL SECURITIES. The Fund may invest up to 20% of its total
assets in lower grade tax-exempt municipal securities or in unrated municipal
securities considered by the Adviser to be of comparable quality. Lower grade
municipal securities are rated between BB and B- by S&P or between Ba and B3 by
Moody's, in each case inclusive of such rating categories. Higher yields are
generally available from municipal securities of such grade. With respect to
such 20% of the Fund's total assets, the Fund has not established any limit on
the percentage of its portfolio which may be invested in securities in any one
rating category.
 
  Investors should carefully consider the risks of owning shares of an
investment company which invests in lower grade municipal securities before
making an investment in the Fund. The higher yield on certain securities held by
the Fund reflects a greater possibility that the financial condition of the
issuer, or adverse changes in general economic conditions, or both, may impair
the ability of the issuer to make payments of income and principal. See "Special
Considerations Regarding the Fund."
 
  The Adviser seeks to minimize the risks involved in investing in lower grade
municipal securities through diversification and careful investment analysis. To
the extent that there is no established retail market for some of the lower
grade municipal securities in which the Fund may invest, trading in such
securities may be relatively inactive. The Adviser is responsible for
determining the net asset value of the Fund, subject to the supervision of the
Board of Trustees of the Trust. During periods of reduced market liquidity and
in the absence of readily available market quotations for lower grade municipal
securities held in the Fund's portfolio, the ability of the Adviser to value the
Fund's securities becomes more difficult and the Adviser's use of judgment may
play a greater role in the valuation of the Fund's securities due to the reduced
availability of reliable objective data. The effects of adverse publicity and
investor perceptions may be more pronounced for securities for which no
established retail market exists as compared with the effects on securities for
which such a market does exist. Further, the Fund may have more difficulty
selling such securities in a timely manner and at their stated value than would
be the case for securities for which an established retail market does exist.
See "Special Considerations Regarding the Fund."
 
                                       14
<PAGE>   156
 
  SELECTION OF INVESTMENTS. The Adviser will buy and sell securities for the
Fund's portfolio with a view to seeking a high level of current income exempt
from federal income tax and will select securities which the Adviser believes
entail reasonable credit risk considered in relation to the investment policies
of the Fund. As a result, the Fund will not necessarily invest in the highest
yielding tax-exempt municipal securities permitted by the investment policies if
the Adviser determines that market risks or credit risks associated with such
investments would subject the Fund's portfolio to excessive risk. The potential
for realization of capital gains resulting from possible changes in interest
rates will not be a major consideration. There is no limitation as to the
maturity of municipal securities in which the Fund may invest. The Adviser may
adjust the average maturity of the Fund's portfolio from time to time, depending
on its assessment of the relative yields available on securities of different
maturities and its expectations of future changes in interest rates. Other than
for tax purposes, frequency of portfolio turnover will generally not be a
limiting factor if the Fund considers it advantageous to purchase or sell
securities. The Fund may have annual portfolio turnover rates in excess of 100%.
A high rate of portfolio turnover involves correspondingly greater brokerage
commission expenses or dealer costs than a lower rate, which expenses and costs
must be borne by the Fund and its shareholders. High portfolio turnover may also
result in the realization of substantial net short-term capital gains and any
distributions resulting from such gains will be taxable. See "Tax Status" in
this Prospectus and "Investment Policies and Restrictions" in the Statement of
Additional Information.
 
  DEFENSIVE STRATEGIES. At times conditions in the markets for tax-exempt
municipal securities may, in the Adviser's judgment, make pursuing the Fund's
basic investment strategy inconsistent with the best interests of its
shareholders. At such times, the Adviser may use alternative strategies
primarily designed to reduce fluctuations in the value of the Fund's assets. In
implementing these "defensive" strategies, the Fund may invest to a substantial
degree in high-quality, short-term municipal obligations. If these high-quality,
short-term municipal obligations are not available or, in the Adviser's
judgment, do not afford sufficient protection against adverse market conditions,
the Fund may invest in taxable obligations. Such taxable obligations may
include: obligations of the U.S. Government, its agencies or instrumentalities;
other debt securities rated within the four highest grades by either S&P or
Moody's; commercial paper rated in the highest grade by either rating service;
certificates of deposit and bankers' acceptances; repurchase agreements with
respect to any of the foregoing investments; or any other fixed-income
securities that the Adviser considers consistent with such strategy.
 
- ------------------------------------------------------------------------------
INVESTMENT PRACTICES
- ------------------------------------------------------------------------------
 
  In connection with the investment policies described above, the Fund also may
engage in strategic transactions and purchase and sell securities on a "when
issued" and "delayed delivery" basis. These investments entail risks. Strategic
transactions
 
                                       15
<PAGE>   157
 
generally will not be treated as investments in tax-exempt municipal securities
for purposes of the Fund's 80% investment policy with respect thereto.
 
  STRATEGIC TRANSACTIONS. The Fund may purchase and sell derivative instruments
such as exchange-listed and over-the-counter put and call options on securities,
financial futures, fixed-income indices and other financial instruments,
purchase and sell financial futures contracts and enter into various interest
rate transactions such as swaps, caps, floors or collars. Collectively, all of
the above are referred to as "Strategic Transactions." Strategic Transactions
may be used to attempt to protect against possible changes in the market value
of securities held in or to be purchased for the Fund's portfolio resulting from
securities markets, to protect the Fund's unrealized gains in the value of its
portfolio securities, to facilitate the sale of such securities for investment
purposes, to manage the effective maturity or duration of the Fund's portfolio,
or to establish a position in the derivatives markets as a temporary substitute
for purchasing or selling particular securities. Any or all of these investment
techniques may be used at any time and there is no particular strategy that
dictates the use of one technique rather than another, as use of any Strategic
Transaction is a function of numerous variables including market conditions. The
ability of the Fund to utilize these Strategic Transactions successfully will
depend on the Adviser's ability to predict pertinent market movements, which
cannot be assured. The Fund will comply with applicable regulatory requirements
when implementing these strategies, techniques and instruments. Strategic
Transactions involving financial futures and options thereon will be purchased,
sold or entered into only for bona fide hedging, risk management or portfolio
management purposes and not for speculative purposes.
 
  Strategic Transactions have risks associated with them including possible
default by the other party to the transaction, illiquidity and, to the extent
the Adviser's view as to certain market movements is incorrect, the risk that
the use of such Strategic Transactions could result in losses greater than if
they had not been used. Use of put and call options may result in losses to the
Fund, force the sale of portfolio securities at inopportune times or for prices
other than at current market values, limit the amount of appreciation the Fund
can realize on its investments or cause the Fund to hold a security it might
otherwise sell. The use of options and futures transactions entails certain
other risks. In particular, the variable degree of correlation between price
movements of futures contracts and price movements in the related portfolio
position of the Fund creates the possibility that losses on the hedging
instrument may be greater than gains in the value of the Fund's position. In
addition, futures and options markets may not be liquid in all circumstances and
certain over-the-counter options may have no markets. As a result, in certain
markets, the Fund might not be able to close out a transaction without incurring
substantial losses, if at all. Although the contemplated use of these futures
contracts and options thereon should tend to minimize the risk of loss due to a
decline in the value of the hedged position, at the same time they tend to limit
any potential gain which might result from an increase in value of such
position. Finally, the daily variation margin requirements for futures contracts
would create a greater ongoing
 
                                       16
<PAGE>   158
 
potential financial risk than would purchases of options, where the exposure is
limited to the cost of the initial premium. Losses resulting from the use of
Strategic Transactions would reduce net asset value, and possibly income, and
such losses can be greater than if the Strategic Transactions had not been
utilized. The Strategic Transactions that the Fund may use and some of their
risks are described more fully in the Fund's Statement of Additional
Information.
 
  Income earned or deemed to be earned, if any, by the Fund from its Strategic
Transactions will generally be taxable income of the Fund. See "Tax Status."
 
   
  "WHEN ISSUED" AND "DELAYED DELIVERY" TRANSACTIONS. The Fund may also purchase
and sell municipal securities on a "when issued" and "delayed delivery" basis.
No income accrues to the Fund on municipal securities in connection with such
purchase transactions prior to the date the Fund actually takes delivery of such
securities. These transactions are subject to market fluctuation; the value of
the municipal securities at delivery may be more or less than their purchase
price, and yields generally available on municipal securities when delivery
occurs may be higher or lower than yields on the municipal securities obtained
pursuant to such transactions. Because the Fund relies on the buyer or seller,
as the case may be, to consummate the transaction, failure by the other party to
complete the transaction may result in the Fund missing the opportunity of
obtaining a price or yield considered to be advantageous. When the Fund is the
buyer in such a transaction, however, it will maintain, in a segregated account
with its custodian, cash or liquid securities having an aggregate value equal to
the amount of such purchase commitments until payment is made. The Fund will
make commitments to purchase municipal securities on such basis only with the
intention of actually acquiring these securities, but the Fund may sell such
securities prior to the settlement date if such sale is considered to be
advisable. To the extent the Fund engages in "when issued" and "delayed
delivery" transactions, it will do so for the purpose of acquiring securities
for the Fund's portfolio consistent with the Fund's investment objective and
policies and not for the purposes of investment leverage. No specific limitation
exists as to the percentage of the Fund's assets which may be used to acquire
securities on a "when issued" or "delayed delivery" basis.
    
 
  OTHER PRACTICES. The Fund has no restrictions on the maturity of municipal
bonds in which it may invest. The Fund will seek to invest in municipal bonds of
such maturities that, in the judgment of the Fund and the Adviser, will provide
a high level of current income consistent with liquidity requirements and market
conditions.
 
  The Fund may borrow amounts up to 5% of its net assets in order to pay for
redemptions when liquidation of portfolio securities is considered
disadvantageous or inconvenient and may pledge up to 10% of its net assets to
secure such borrowings.
 
                                       17
<PAGE>   159
 
  The Fund generally will not invest more than 25% of its total assets in any
industry, nor will the Fund generally invest more than 5% of its assets in the
securities of any single issuer. Governmental issuers of municipal securities
are not considered part of any "industry." However, municipal securities backed
only by the assets and revenues of nongovernmental users may for this purpose be
deemed to be issued by such nongovernmental users, and the 25% limitation would
apply to such obligations. It is nonetheless possible that the Fund may invest
more than 25% of its assets in a broader segment of the municipal securities
market, such as revenue obligations of hospitals and other health care
facilities, housing agency revenue obligations, or airport revenue obligations
if the Adviser determines that the yields available from obligations in a
particular segment of the market justified the additional risks associated with
a large investment in such segment. Although such obligations could be supported
by the credit of governmental users, or by the credit of nongovernmental users
engaged in a number of industries, economic, business, political and other
developments generally affecting the revenues of such users (for example,
proposed legislation or pending court decisions affecting the financing of such
projects and market factors affecting the demand for their services or products)
may have a general adverse effect on all municipal securities in such a market
segment. The Fund reserves the right to invest more than 25% of its assets in
industrial development bonds or in issuers located in the same state, although
it has no present intention to invest more than 25% of its assets in issuers
located in the same state. If the Fund were to invest more than 25% of its
assets in issuers located in the same state, it would be more susceptible to
adverse economic, business, or regulatory conditions in that state.
 
  PORTFOLIO TRANSACTIONS AND BROKERAGE ALLOCATION. 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 prices and any
brokerage commissions. The securities in which the Fund invests are traded
principally in the over-the-counter market. In the over-the-counter market,
securities are generally traded on a net basis with dealers acting as principal
for their own accounts without a stated commission, although the price of the
security usually includes a mark-up to the dealer. Securities purchased in
underwritten offerings generally include, in the price, a fixed amount of
compensation for the managers, underwriters and dealers. The Fund may also
purchase certain money market instruments directly from an issuer, in which case
no commissions or discounts are paid. Purchases and sales of bonds on a stock
exchange are effected through brokers who charge a commission for their
services.
 
  The Adviser is responsible for effecting securities transactions of the Fund
and will do so in a manner deemed fair and reasonable to shareholders of the
Fund and not according to any formula. The Adviser's primary considerations in
selecting the manner of executing securities transactions for the Fund will be
prompt execution of orders, the size and breadth of the market for the security,
the reliability, integrity and financial condition and execution capability of
the firm, the size of and difficulty in executing the order, and the best net
price. There are many instances
 
                                       18
<PAGE>   160
 
when, in the judgment of the Adviser, more than one firm can offer comparable
execution services. In selecting among such firms, consideration is given to
those firms which supply research and other services in addition to execution
services. However, it is not the policy of the Adviser, absent special
circumstances, to pay higher commissions to a firm because it has supplied such
services.
 
  In effecting purchases and sales of the Fund's portfolio securities, the
Adviser and the Fund may place orders with and pay brokerage commissions to
brokers, including brokers which may be affiliated with the Fund, the Adviser
and the Distributor or dealers participating in the offering of the Fund's
shares. In addition, in selecting among firms to handle a particular
transaction, the Adviser and the Fund may take into account whether the firm has
sold or is selling shares of the Fund. See "Portfolio Transactions and Brokerage
Allocation" in the Statement of Additional Information for more information.
 
- ------------------------------------------------------------------------------
SPECIAL CONSIDERATIONS REGARDING THE FUND
- ------------------------------------------------------------------------------
 
  In normal circumstances, the Fund may invest up to 20% of its total assets in
lower grade tax-exempt municipal securities or in unrated municipal securities
considered by the Adviser to be of comparable quality. Lower grade municipal
securities are rated between BB and B- by S&P or between Ba and B3 by Moody's,
in each case inclusive of such rating categories. Investment in lower grade
municipal securities involves special risks as compared with investment in
higher grade municipal securities. The market for lower grade municipal
securities is considered to be less liquid than the market for investment grade
municipal securities which may adversely affect the ability of the Fund to
dispose of such securities in a timely manner at a price which reflects the
value of such security in the Adviser's judgement. The market price for less
liquid securities tends to be more volatile than the market price for more
liquid securities. Illiquid securities and the absence of readily available
market quotations with respect thereto may make the Adviser's valuation of such
securities more difficult, and the Adviser's judgment may play a greater role in
the valuation of the Fund's securities. Lower grade municipal securities
generally involve greater credit risk than higher grade municipal securities and
are more sensitive to adverse economic changes, significant increases in
interest rates and individual issuer developments. Because issuers of lower
grade municipal securities frequently choose not to seek a rating of their
municipal securities, the Fund will rely more heavily on the Adviser's ability
to determine the relative investment quality of such securities than if the Fund
invested exclusively in higher grade municipal securities. The Fund may, if
deemed appropriate by the Adviser, retain a security whose rating has been
downgraded below B- by S&P or below B3 by Moody's, or whose rating has been
withdrawn. More detailed information concerning the risks associated with
instruments in lower grade municipal securities is included in the Fund's
Statement of Additional Information.
 
                                       19

  The Fund may invest a substantial portion of its assets in municipal
securities that pay interest that is subject to the federal alternative minimum
tax. The Fund may not be a suitable investment for investors who are already
subject to the federal alternative minimum tax or who would become subject to
the federal alternative minimum tax as a result of an investment in the Fund.
 
   
  The table below sets forth the percentages of the Fund's assets invested
during the fiscal year ended December 31, 1996 in the various Moody's and S&P
rating categories and in unrated securities determined by the Adviser to be of
comparable quality. The percentages are based on the dollar-weighted average of
credit ratings of all municipal securities held by the Fund during the 1996
fiscal year, computed on a monthly basis.

  PORTFOLIO MANAGEMENT.  David C. Johnson, a Senior Vice President of the
Adviser has been primarily responsible for the day-to-day management of the
Fund's portfolio since August, 1990. Mr. Johnson has been employed by the
Adviser since April 1989.
- ------------------------------------------------------------------------------
ALTERNATIVE SALES ARRANGEMENTS
- ------------------------------------------------------------------------------
 
  The Alternative Sales Arrangements permit an investor to choose the method of
purchasing shares that is more beneficial to the investor, taking into account
the amount of the purchase, the length of time the investor expects to hold the
shares, whether the investor wishes to receive dividends in cash or to reinvest
them in additional shares of the Fund, and other circumstances. Investors should
consider such factors together with the amount of sales charges and accumulated
distribution and service fees with respect to each class of shares that may be
incurred over the anticipated duration of their investment in the Fund.
 
  The Fund offers three classes of shares, designated Class A Shares, Class B
Shares and Class C Shares. Shares of each class are offered at a price equal to
their net asset value per share plus a sales charge which, at the election of
the purchaser, may be imposed (a) at the time of purchase ("Class A Shares") or
(b) on a contingent deferred basis (Class A Share accounts over $1 million,
"Class B Shares" and "Class C Shares"). Class A Share accounts over $1 million
or otherwise subject to a contingent deferred sales charge ("CDSC"), Class B
Shares and Class C Shares sometimes are referred to herein collectively as
"Contingent Deferred Sales Charge Shares" or "CDSC Shares."

  The minimum initial investment with respect to each class of shares is $500.
The minimum subsequent investment with respect to each class of shares is $25.
It is presently the policy of the Distributor not to accept any order for Class
B Shares in an amount of $500,000 or more and not to accept any order for Class
C Shares in an amount of $1 million or more because it ordinarily will be more
advantageous for an investor making such an investment to purchase Class A
Shares.
 
  An investor should carefully consider the sales charges applicable to each
class of shares and the estimated period of their investment to determine which
class of shares is more beneficial for the investor to purchase. For example,
investors who would qualify for a significant purchase price discount from the
maximum sales charge on Class A Shares may determine that payment of such a
reduced front-end sales charge is superior to electing to purchase Class B
Shares or Class C Shares, each with no front-end sales charge but subject to a
CDSC and a higher aggregate distribution and service fee. However, because
initial sales charges are deducted at the time of purchase of Class A Share
accounts under $1 million, a purchaser of such Class A Shares would not have all
of his or her funds invested initially and, therefore, would initially own fewer
shares than if Class B Shares or Class C Shares had been purchased. On the other
hand, an investor whose purchase would not qualify for price discounts
applicable to Class A Shares and intends to remain invested until after the
expiration of the applicable CDSC may wish to defer the sales charge and have
all his or her funds initially invested in Class B Shares or Class C Shares. If
such an investor anticipates that he or she will redeem such shares prior to the
expiration of the CDSC period applicable to Class B Shares, the investor may
wish to acquire Class C Shares. Investors must weigh the benefits of deferring
the sales charge and having all of their funds invested against the higher
aggregate distribution and service fee applicable to Class B Shares and Class C
Shares (discussed below).
 
  Each class of shares represents an interest in the same portfolio of
investments of the Fund and has the same rights, except each class of shares (i)
bears those distribution fees, service fees and administrative expenses
applicable to the respective class of shares as a result of its sales
arrangements, (ii) has exclusive voting rights with respect to those provisions
of the Fund's Rule 12b-1 distribution plan which relate only to such class and
(iii) has a different exchange privilege. Generally, a class of shares subject
to a higher ongoing distribution and service fee or subject to the conversion
feature will have a higher expense ratio and pay lower dividends than a class of
shares subject to a lower ongoing distribution and service fee or not subject to
the conversion feature. The per share net asset values of the different classes
of shares are expected to be substantially the same; from time to time, however,
the per share net asset values of the classes may differ. The net asset value
per share of each class of shares of the Fund will be determined as described in
this Prospectus under "Purchase of Shares -- Net Asset Value."
 
   
  The administrative expenses that may be allocated to a specific class of
shares may consist of (i) ACCESS' expenses attributable to a specific class of
shares,
    
 
                                       23
<PAGE>   165
 
which expenses typically will be higher with respect to classes of shares
subject to the conversion feature; (ii) printing and postage expenses related to
preparing and distributing materials such as shareholder reports, prospectuses
and proxy statements to current shareholders of a specific class; (iii)
Securities and Exchange Commission (the "SEC") registration fees incurred by a
class of shares; (iv) the expense of administrative personnel and services as
required to support the shareholders of a specific class; (v) Trustees' fees or
expense incurred as a result of issues relating to one class of shares; (vi)
accounting expenses relating solely to one class of shares; and (vii) any other
incremental expenses subsequently identified that should be properly allocated
to one or more classes of shares. All such expenses incurred by a class will be
borne on a pro rata basis by the outstanding shares of such class. All
allocations of administrative expenses to a particular class of shares will be
limited to the extent necessary to preserve the Fund's qualification as a
regulated investment company under the Internal Revenue Code of 1986, as amended
(the "Code").

PURCHASE OF SHARES
- ------------------------------------------------------------------------------
 
   
  The Fund offers three classes of shares for sale to the public on a continuous
basis through the Distributor, as principal underwriter, which is located at One
Parkview Plaza, Oakbrook Terrace, Illinois 60181. Shares are also offered
through members of the National Association of Securities Dealers, Inc. ("NASD")
acting as securities dealers ("dealers") and through NASD members acting as
brokers for investors ("brokers") or eligible non-NASD members acting as agents
for investors ("financial intermediaries"). The Fund reserves the right to
suspend or terminate the continuous public offering of its shares at any time
and without prior notice.
    
 
  The Fund's shares are offered at the net asset value per share next computed
after an investor places an order to purchase directly with the investor's
broker, dealer or financial intermediary or directly with the Distributor plus
any applicable sales charge. Sales personnel or brokers, dealers and financial
intermediaries distributing the Fund's shares may receive different compensation
for selling different classes of shares. It is the responsibility of the
investor's broker, dealer or financial intermediary to transmit the order to the
Distributor. Because the Fund generally will determine net asset value once each
business day as of the close of business, purchase orders placed through an
investor's broker, dealer or financial intermediary must be transmitted to the
Distributor by such broker, dealer or financial intermediary prior to such time
in order for the investor's order to be fulfilled on the basis of the net asset
value to be determined that day. Any change in the purchase price due to the
failure of the Distributor to receive a purchase order prior to such time must
be settled between the investor and the broker, dealer or financial intermediary
submitting the order.
 
  The Distributor may from time to time implement programs under which a broker,
dealer or financial intermediary's sales force may be eligible to win nominal
 
                                       24
<PAGE>   166
 
   
awards for certain sales efforts or under which the Distributor will reallow to
any broker, dealer or financial intermediary that sponsors sales contests or
recognition programs conforming to criteria established by the Distributor, or
participates in sales programs sponsored by the Distributor, an amount not
exceeding the total applicable sales charges on the sales generated by the
broker, dealer or financial intermediary at the public offering price during
such programs. Other programs provide, among other things and subject to certain
conditions, for certain favorable distribution arrangements for shares of the
Fund. Also, the Distributor in its discretion may from time to time, pursuant to
objective criteria established by it, pay fees to, and sponsor business seminars
for, qualifying brokers, dealers or financial intermediaries for certain
services or activities which are primarily intended to result in sales of shares
of the Fund. Fees may include payment for travel expenses, including lodging,
incurred in connection with trips taken by invited registered representatives
and members of their families to locations within or outside of the United
States for meetings or seminars of a business nature. In some instances
additional compensation or promotional incentives may be offered to brokers,
dealers or financial intermediaries that have sold or may sell significant
amounts of shares during specified periods of time. The Distributor may provide
additional compensation to Edward D. Jones & Co. or an affiliate thereof based
on a combination of its sales of shares and increases in assets under
management. Such payments to brokers, dealers and financial intermediaries for
sales contests, other sales programs and seminars are made by the Distributor
out of its own assets and not out of the assets of the Fund. Such fees paid for
such services and activities with respect to the Fund will not exceed in the
aggregate 1.25% of the average total daily net assets of the Fund on an annual
basis. These programs will not change the price an investor pays for shares or
the amount that the Fund will receive from such sale.
    
 
CLASS A SHARES
 
  The public offering price of Class A Shares is equal to the net asset value
per share plus an initial sales charge which is a variable percentage of the
offering price depending upon the amount of the sale. The table below shows
total sales charges and dealer concessions reallowed to dealers and agency
commissions paid to brokers with respect to sales of Class A Shares. The sales
charge is allocated between the investor's broker, dealer or financial
intermediary and the Distributor. As indicated previously, at the discretion of
the Distributor, the entire sales charge may be reallowed to such broker, dealer
or financial intermediary. The staff of the SEC has taken the position that
brokers, dealers or financial intermediaries who receive 90% or more of the
sales charge may be deemed to be "underwriters" as that term is defined in the
Securities Act of 1933, as amended.

   * No sales charge is payable at the time of purchase on investments of $1
     million or more, although for such investments the Fund imposes a CDSC
     of 1.00% on redemptions made within one year of the purchase. A
     commission will be paid to brokers, dealers or financial intermediaries
     who initiate and are responsible for purchases of $1 million or more as
     follows: 1.00% on sales to $2 million, plus 0.80% on the next $1 million
     and 0.50% on the excess over $3 million. See "Purchase of Shares --
     Deferred Sales Charge Alternatives" for additional information with
     respect to CDSCs.
    
 
QUANTITY DISCOUNTS
 
  Investors purchasing Class A Shares may, under certain circumstances, be
entitled to pay reduced sales charges. The circumstances under which such
investors may pay reduced sales charges are described below.
 
  Investors, or their brokers, dealers or financial intermediaries, must notify
the Fund whenever a quantity discount is applicable to purchases. Upon such
notification, an investor will receive the lowest applicable sales charge.
Quantity discounts may be modified or terminated at any time. For more
information about quantity discounts, investors should contact their broker,
dealer or financial intermediary or the Distributor.
 
   
  A person eligible for a reduced sales charge includes an individual, their
spouse and children under 21 years of age and any corporation, partnership, or
sole proprietorship which is 100% owned, either alone or in combination, by any
of the foregoing; a trustee or other fiduciary of a single trust estate or a
single fiduciary account; or a "company" as defined is section 2(a)(8) of the
1940 Act.
    
 
   
  As used herein, "Participating Funds" refers to certain open-end investment
companies advised by the Adviser or Van Kampen American Capital Asset
Management, Inc. and distributed by the Distributor. Additional funds may be
added from time to time as determined by the Fund's Board of Trustees as
Participating Funds.
    
 
   
  VOLUME DISCOUNTS. The size of investment shown in the preceding sales charge
table applies to the total dollar amount being invested by any person at any one
time
    
 
                                       26
<PAGE>   168
 
   
in Class A Shares of the Fund, or in any combination of shares of the Fund and
shares of other Participating Funds, although other Participating Funds may have
different sales charges.
    
 
   
  CUMULATIVE PURCHASE DISCOUNT. The size of investment shown in the preceding
sales charge table may also be determined by combining the amount being invested
in Class A Shares of the Fund with other shares of the Fund and shares of
Participating Funds, plus the current offering price of all shares of the Fund
and other Participating Funds which have been previously purchased and are still
owned.
    
 
   
  LETTER OF INTENT. A Letter of Intent provides an opportunity for an investor
to obtain a reduced sales charge by aggregating the amount being invested over a
13-month period to determine the sales charge as outlined in the preceding sales
charge table. The size of investment shown in the preceding table includes the
amount of intended purchases of Class A Shares of the Fund with other shares of
the Fund and shares of the Participating Funds plus the value of all shares of
the Fund and other Participating Funds previously purchased during such 13-month
period and still owned. An investor may elect to compute the 13-month period
starting up to 90 days before the date of execution of a Letter of Intent. Each
investment made during the period receives the reduced sales charge applicable
to the total amount of the investment goal. If trades not initially made under a
Letter of Intent subsequently qualify for a lower sales charge through the
90-day back-dating provision, an adjustment will be made at the expiration of
the Letter of Intent to give effect to the lower charge. If the goal is not
achieved within the 13-month period, the investor must pay the difference
between the sales charge applicable to the purchases made and the sales charges
previously paid. When an investor signs a Letter of Intent, shares equal to at
least 5% of the total purchase amount of the level selected will be restricted
from sale or redemption by the investor until the Letter of Intent is satisfied
or any additional sales charges have been paid; if the Letter of Intent is not
satisfied by the investor and any additional sales charges are not paid,
sufficient restricted shares will be redeemed by the Fund to pay such charges.
Additional information is contained in the application accompanying this
Prospectus.
    
 
OTHER PURCHASE PROGRAMS
 
   
  Purchasers of Class A Shares may be entitled to reduced initial sales charges
in connection with unit investment trust reinvestment programs and purchases by
registered representatives of selling firms or purchases by persons affiliated
with the Fund or the Distributor. The Fund reserves the right to modify or
terminate these arrangements at any time.
    
 
  UNIT INVESTMENT TRUST REINVESTMENT PROGRAMS. The Fund permits unitholders of
unit investment trusts to reinvest distributions from such trusts in Class A
Shares of the Fund at net asset value with no minimum initial or subsequent
investment requirement if the administrator of an investor's unit investment
trust program meets certain uniform criteria relating to cost savings by the
Fund and the
 
                                       27
<PAGE>   169
 
Distributor. The total sales charge for all other investments made from unit
trust distributions will be 1.00% of the offering price (1.01% of net asset
value). Of this amount, the Distributor will pay to the broker, dealer or
financial intermediary, if any, through which such participation in the
qualifying program was initiated 0.50% of the offering price as a dealer
concession or agency commission. Persons desiring more information with respect
to this program, including the applicable terms and conditions thereof, should
contact their broker, dealer, financial intermediary or the Distributor.
 
   
  The administrator of such a unit investment trust must have an agreement with
the Distributor pursuant to which the administrator will (1) submit a single
bulk order and make payment with a single remittance for all investments in the
Fund during each distribution period by all investors who choose to invest in
the Fund through the program and (2) provide ACCESS with appropriate backup data
for each participating investor in a computerized format fully compatible with
ACCESS' processing system.
    
 
   
  As further requirements for obtaining these special benefits, the Fund also
requires that all dividends and other distributions by the Fund be reinvested in
additional shares without any systematic withdrawal program. There will be no
minimum for reinvestments from unit investment trusts. The Fund will send
account activity statements to such participants on a monthly basis only, even
if their investments are made more frequently. The Fund reserves the right to
modify or terminate this program at any time.
    
 
  NAV PURCHASE OPTIONS. Class A Shares of the Fund may be purchased at net asset
value, upon written assurance that the purchase is made for investment purposes
and that the shares will not be resold except through redemption by the Fund,
by:
 
   
  (1) Current or retired trustees or directors of funds advised by the Adviser
      or Van Kampen American Capital Asset Management, Inc. and such persons'
      families and their beneficial accounts.
    
 
   
  (2) Current or retired directors, officers and employees of Morgan Stanley
      Group Inc. and any of its subsidiaries, employees of an investment
      subadviser to any fund described in (1) above or an affiliate of such
      subadviser; and such persons' families and their beneficial accounts.
    
 
   
  (3) Directors, officers, employees and registered representatives of financial
      institutions that have a selling group agreement with the Distributor and
      their spouses and children under 21 years of age when purchasing for any
      accounts they beneficially own, or, in the case of any such financial
      institution, when purchasing for retirement plans for such institution's
      employees.
    
 
  (4) Registered investment advisers, trust companies and bank trust departments
      investing on their own behalf or on behalf of their clients provided that
      the
 
                                       28
<PAGE>   170
 
   
      aggregate amount invested in Class A Shares of the Fund alone, or any
      combination of shares of the Fund and shares of other Participating Funds
      as described herein under "Purchase of Shares -- Class A Shares --
      Quantity Discounts," during the 13-month period commencing with the first
      investment pursuant hereto equals at least $1 million. The Distributor may
      pay brokers, dealers or financial intermediaries through which purchases
      are made an amount up to 0.50% of the amount invested, over a 12-month
      period following such transaction.
    
 
   
  (5) Trustees and other fiduciaries purchasing shares for retirement plans of
      organizations with retirement plan assets of $3 million or more and which
      invest in multiple fund families through national wirehouse alliance
      programs.
    
 
  (6) Accounts as to which a broker, dealer or financial intermediary charges an
      account management fee ("wrap accounts"), provided the broker, dealer or
      financial intermediary has a separate agreement with the Distributor.
 
  (7) Investors purchasing shares of the Fund with redemption proceeds from
      other mutual fund complexes on which the investor has paid a front-end
      sales charge or was subject to a deferred sales charge, whether or not
      paid, if such redemption has occurred no more than 30 days prior to such
      purchase.
 
   
  (8) Trusts created under pension, profit sharing or other employee benefit
      plans qualified under Section 401(a) of the Code, or custodial accounts
      held by a bank created pursuant to Section 403(b) of the Code and
      sponsored by non-profit organizations defined under Section 501(c)(3) of
      the Code and assets held by an employer or trustee in connection with an
      eligible deferred compensation plan under Section 457 of the Code. Such
      plans will qualify for purchases at net asset value provided, for plans
      initially establishing accounts with the Distributor in the Participating
      Funds after February 1, 1997, that (1) the initial amount invested in the
      Participating Funds is at least $500,000 or (2) such shares are purchased
      by an employer sponsored plan with more than 100 eligible employees. Such
      plans that have been established with a Participating Fund or have
      received proposals from the Distributor prior to February 1, 1997 based on
      net asset value purchase privileges previously in effect will be qualified
      to purchase shares of the Participating Funds at net asset value for
      accounts established on or before May 1, 1997. Section 403(b) and similar
      accounts for which Van Kampen American Capital Trust Company served as
      custodian will not be eligible for net asset value purchases based on the
      aggregate investment made by the plan or the number of eligible employees,
      except under certain uniform criteria established by the Distributor from
      time to time. Prior to February 1, 1997, a commission will be paid to
      authorized dealers who initiate and are responsible for such purchases
      within a rolling twelve-month period as follows: 1.00% on sales to $5
      million, plus 0.50% on the next $5 million and 0.25% on the excess over
      $10 million. For purchases on February 1, 1997
    
 
                                       29
<PAGE>   171
 
   
      and thereafter, a commission will be paid as follows: 1.00% on sales to $2
      million, plus 0.80% on the next $1 million, plus 0.50% on the next $47
      million and 0.25% on the excess over $50 million.
    
 
   
  (9) Individuals who are members of a "qualified group". For this purpose, a
      qualified group is one which (i) has been in existence for more than six
      months, (ii) has a purpose other than to acquire shares of the Fund or
      similar investments, (iii) has given and continues to give its endorsement
      or authorization, on behalf of the group, for purchase of shares of the
      Fund and other Participating Funds, (iv) has a membership that the
      authorized dealer can certify as to the group's members and (v) satisfies
      other uniform criteria established by the Distributor for the purpose of
      realizing economics of scale in distributing such shares. A qualified
      group does not include one whose sole organizational nexus, for example,
      is that its participants are credit card holders of the same institution,
      policy holders of an insurance company, customers of a bank or
      broker-dealer, clients of an investment adviser or other similar groups.
      Shares purchased in each group's participants account in connection with
      this privilege will be subject to a CDSC of 1.00% in the event of
      redemption within one year of purchase, and a commission will be paid to
      authorized dealers who initiate and are responsible for such sales to each
      individual as follows: 1.00% on sales to $2 million, plus 0.80% on the
      next $1 million and 0.50% on the excess over $3 million.
    
 
   
The term "families" includes a person's spouse, children under 21 years of age
and grandchildren, parents, and a person's spouse's parents.
    
 
   
  Purchase orders made pursuant to clause (4) may be placed either through
authorized brokers, dealers or financial intermediaries as described above or
directly with ACCESS, the investment adviser, trust company or bank trust
department, provided that ACCESS receives federal funds for the purchase by the
close of business on the next business day following acceptance of the order. An
authorized broker, dealer or financial intermediary may charge a transaction fee
for placing an order to purchase shares pursuant to this provision or for
placing a redemption order with respect to such shares. The Fund may terminate,
or amend the terms of, offering shares of the Fund at net asset value to such
groups at any time.
    
 
DEFERRED SALES CHARGE ALTERNATIVES
 
  Investors choosing the deferred sales charge alternative may purchase Class A
Shares in an amount of $1 million or more, Class B Shares or Class C Shares. The
public offering price of a CDSC Share is equal to the net asset value per share
without the imposition of a sales charge at the time of purchase. CDSC Shares
are sold without an initial sales charge so that the Fund may invest the full
amount of the investor's purchase payment. The Distributor will compensate
brokers, dealers and financial intermediaries participating in the continuous
public offering of the CDSC Shares out of its own assets, and not out of assets
of the Fund, as a percentage rate of the dollar value of the CDSC Shares
purchased from the Fund
 
                                       30
<PAGE>   172
 
   
by such brokers, dealers and financial intermediaries which percentage rate will
be equal to (i) with respect to Class A Shares, 1.00% on sales to $2 million,
plus 0.80% on the next $1 million and 0.50% on the excess over $3 million; (ii)
4.00% with respect to Class B Shares; and (iii) 1.00% with respect to Class C
Shares. Such compensation will not change the price an investor will pay for
CDSC Shares or the amount that the Fund will receive from such sale.
    
 
   
  CDSC Shares redeemed within a specified period of time generally will be
subject to a CDSC at the rates set forth below charged as a percentage of the
dollar amount subject thereto. The amount of the CDSC will vary depending on (i)
the class of CDSC Shares to which such shares belong and (ii) the number of
years from the time of payment for the purchase of the CDSC Shares until the
time of their redemption. The charge will be assessed on an amount equal to the
lesser of the then current market value or the original purchase price of the
CDSC Shares being redeemed. Accordingly, no sales charge will be imposed on
increases in net asset value above the initial purchase price. In addition, no
CDSC will be assessed on CDSC Shares derived from reinvestment of dividends or
capital gains distributions. Solely for purposes of determining the number of
years from the time of any payment for the purchases of CDSC Shares, all
payments during a month will be aggregated and deemed to have been made on the
last day of the month.
    
 
   
  Proceeds from the CDSC and the distribution fee applicable to a class of CDSC
Shares are paid to the Distributor and are used by the Distributor to defray its
expenses related to providing distribution related services to the Fund in
connection with the sale of shares of such class of CDSC Shares, such as the
payment of compensation to selected dealers and agents and for selling such
shares. The combination of the CDSC and the distribution fees facilitates the
ability of the Fund to sell such CDSC Shares without a sales charge being
deducted at the time of purchase.
    
 
   
  In determining whether a CDSC is applicable to a redemption of CDSC Shares, it
will be assumed that the redemption is made first of any CDSC Shares acquired
pursuant to reinvestment of dividends or distributions, second of CDSC Shares
that have been held for a sufficient period of time such that the CDSC no longer
is applicable to such shares, third of Class A Shares in the shareholder's Fund
account that have converted from Class B Shares or Class C Shares, if any, and
fourth of CDSC Shares held longest during the period of time that a CDSC is
applicable to such CDSC Shares. The charge will not be applied to dollar amounts
representing an increase in the net asset value since the time of purchase.
    
 
  To provide an example, assume an investor purchased 100 Class B Shares at $10
per share (at a cost of $1,000) and in the second year after purchase, the net
asset value per share is $12 and, during such time, the investor has acquired 10
additional Class B Shares upon dividend reinvestment. If at such time the
investor makes his first redemption of 50 shares (proceeds of $600), 10 shares
will not be subject to charge because of dividend reinvestment. With respect to
the remaining 40 shares, the charge is applied only to the original cost of $10
per share and not to the
 
                                       31
<PAGE>   173
 
increase in net asset value of $2 per share. Therefore, $400 of the $600
redemption proceeds will be charged at a rate of 3.75% (the applicable rate in
the second year after purchase).
 
   
  CLASS A SHARE PURCHASES OF $1 MILLION OR MORE. No sales charge is payable at
the time of purchase on investments in Class A Shares of $1 million or more,
although for such investments the Fund imposes a CDSC of 1.00% on redemptions
made within one year of the purchase. A commission will be paid to dealers who
initiate and are responsible for purchases of $1 million or more as follows: 1%
on sales to $2 million, plus 0.80% on the next $1 million and 0.50% on the
excess over $3 million.
    
 
   
  CLASS B SHARES. Class B Shares redeemed within six years of purchase generally
will be subject to a CDSC at the rates set forth below, charged as a percentage
of the dollar amount subject thereto:

  The CDSC generally is waived on redemptions of Class B Shares made pursuant to
the Systematic Withdrawal Plan. See "Shareholder Services -- Systematic
Withdrawal Plan."
    
 
   
  CLASS C SHARES. Class C Shares redeemed within the first 12 months of purchase
generally will be subject to a CDSC of 1.00% of the dollar amount subject
thereto. Class C Shares redeemed thereafter will not be subject to a CDSC.
    
 
   
  CONVERSION FEATURE. Class B Shares purchased on or after June 1, 1996 and any
dividend reinvestment plan shares received thereon, automatically convert to
Class A Shares eight years after the end of the calendar month in which the
shares were purchased. Class B Shares purchased before June 1, 1996, and any
dividend reinvestment plan shares received thereon, automatically convert to
Class A Shares six years after the end of the calendar month in which the shares
were purchased. Class C Shares purchased before January 1, 1997, and any
dividend reinvestment plan shares received thereon, automatically convert to
Class A Shares ten years after the end of the calendar month in which such
shares were purchased. Such conversion will be on the basis of the relative net
asset values per share, without the imposition of any sales load, fee or other
charge.
    
 
                                       32
<PAGE>   174
 
   
  The conversion of such shares to Class A Shares is subject to the continuing
availability of an opinion of counsel to the effect that (i) the assessment of
the higher distribution and service fees and ACCESS' costs with respect to such
shares does not result in the Fund's dividends or distributions constituting
"preferential dividends" under the Code, and (ii) that the conversion of such
shares does not constitute a taxable event under federal income tax law. The
conversion may be suspended if such an opinion is no longer available and such
shares might continue to be subject to the higher aggregate fees applicable to
such class of shares for an indefinite period.
    
 
   
  WAIVER OF CONTINGENT DEFERRED SALES CHARGE. The CDSC is waived on redemptions
of Class B Shares and Class C Shares (i) following the death or disability (as
defined in the Code) of a shareholder, (ii) in connection with required minimum
distributions from an IRA or other retirement plan, (iii) pursuant to the Fund's
systematic withdrawal plan but limited to 12% annually of the initial value of
the account, and (iv) effected pursuant to the right of the Fund to liquidate a
shareholder's account as described herein under "Redemption of Shares." The CDSC
also is waived on redemptions of Class C Shares as it relates to the
reinvestment of redemption proceeds in shares of the same class of the Fund
within 120 days after redemption. See "Shareholder Services" and "Redemption of
Shares" for further discussion of the waiver provisions.
    
 
NET ASSET VALUE
 
  The net asset value per share of the Fund will be determined separately for
each class of shares. The net asset value per share of a given class of shares
of the Fund is determined by calculating the total value of the Fund's assets
attributable to such class of shares, deducting its total liabilities
attributable to such class of shares, and dividing the result by the number of
shares of such class outstanding. The net asset value for the Fund is computed
once daily as of 5:00 p.m. Eastern time Monday through Friday, except on
customary business holidays, or except on any day on which no purchase or
redemption orders are received, or there is not a sufficient degree of trading
in the Fund's portfolio securities such that the Fund's net asset value per
share might be materially affected. The Fund reserves the right to calculate the
net asset value and to adjust the public offering price based thereon more
frequently than once a day if deemed desirable. The net asset value per share of
the different classes of shares are expected to be substantially the same; from
time to time, however, the per share net asset value of the different classes of
shares may differ.
 
  Portfolio securities are valued by using market quotations, prices provided by
market makers or estimates of market values obtained from yield data relating to
instruments or securities with similar characteristics in accordance with
procedures established in good faith by the Board of Trustees of the Trust, of
which the Fund is a series. Securities with remaining maturities of 60 days or
less are valued at amortized cost when amortized cost is determined in good
faith by or under the
 
                                       33
<PAGE>   175
 
direction of the Board of Trustees of the Trust to be representative of the fair
value at which it is expected such securities may be resold. Any securities or
other assets for which current market quotations are not readily available are
valued at their fair value as determined in good faith under procedures
established by and under the general supervision of the Board of Trustees of the
Trust.
 
- ------------------------------------------------------------------------------
SHAREHOLDER SERVICES
- ------------------------------------------------------------------------------
 
  The Fund offers a number of shareholder services designed to facilitate
investment in its shares at little or no extra cost to the investor. Below is a
description of such services. Unless otherwise described below, each of these
services may be modified or terminated by the Fund at any time.
 
   
  INVESTMENT ACCOUNT. ACCESS, transfer agent for the Fund and a wholly-owned
subsidiary of Van Kampen American Capital, performs bookkeeping, data processing
and administration services related to the maintenance of shareholder accounts.
Each shareholder has an investment account under which shares are held by
ACCESS. Except as described in this Prospectus, after each share transaction in
an account, the shareholder receives a statement showing the activity in the
account. Each shareholder will receive statements at least quarterly from ACCESS
showing any reinvestments of dividends and capital gains distributions and any
other activity in the account since the preceding statement. Such shareholders
also will receive separate confirmations for each purchase or sale transaction
other than reinvestment of dividends and capital gains distributions and
systematic purchases or redemptions. Additions to an investment account may be
made at any time by purchasing shares through authorized brokers, dealers or
financial intermediaries or by mailing a check directly to ACCESS.
    
 
  SHARE CERTIFICATES. Generally, the Fund will not issue share certificates.
However, upon written or telephone request to the Fund, a share certificate will
be issued, representing shares (with the exception of fractional shares) of the
Fund. A shareholder will be required to surrender such certificates upon
redemption thereof. In addition, if such certificates are lost the shareholder
must write to Van Kampen American Capital Funds, c/o ACCESS, P.O. Box 418256,
Kansas City, MO 64141-9256, requesting an "affidavit of loss" and to obtain a
Surety Bond in a form acceptable to ACCESS. On the date the letter is received
ACCESS will calculate a fee for replacing the lost certificate equal to no more
than 2.00% of the net asset value of the issued shares and bill the party to
whom the replacement certificate was mailed.
 
   
  REINVESTMENT PLAN. A convenient way for investors to accumulate additional
shares is by accepting dividends and capital gains distributions in shares of
the Fund. Such shares are acquired at net asset value per share (without sales
charge) on the record date of such dividend or distribution. Unless the
shareholder instructs otherwise, the reinvestment plan is automatic. This
instruction may be made by telephone by calling (800) 421-5666 ((800) 421-2833
for the hearing impaired) or
    
 
                                       34
<PAGE>   176
 
in writing to ACCESS. The investor may, on the initial application or prior to
any declaration, instruct that dividends be paid in cash and capital gains
distributions be reinvested at net asset value, or that both dividends and
capital gains distributions be paid in cash. For further information, see
"Distributions from the Fund."
 
  AUTOMATIC INVESTMENT PLAN. An automatic investment plan is available under
which a shareholder can authorize ACCESS to charge a bank account on a regular
basis to invest pre-determined amounts in the Fund. Additional information is
available from the Distributor or authorized brokers, dealers or financial
intermediaries.
 
   
  DIVIDEND DIVERSIFICATION. A shareholder may, upon written request or by
completing the appropriate section of the application form accompanied by this
Prospectus or by calling (800) 421-5666 ((800) 421-2833 for the hearing
impaired), elect to have all dividends and other distributions paid on a class
of shares of the Fund invested into shares of the same class of any other
Participating Fund so long as a pre-existing account for such class of shares
exists for such shareholder.
    
 
  If the qualified pre-existing account does not exist, the shareholder must
establish a new account subject to minimum investment and other requirements of
the fund into which distributions would be invested. Distributions are invested
into the selected fund at its net asset value as of the payable date of the
distribution only if shares of such selected fund have been registered for sale
in the investor's state.
 
   
  EXCHANGE PRIVILEGE. Shares of the Fund may be exchanged with shares of another
Participating Fund subject to certain limitations. Before effecting an exchange,
shareholders in the Fund should obtain and read a current prospectus of the fund
into which the exchange is to be made. SHAREHOLDERS MAY ONLY EXCHANGE INTO SUCH
OTHER FUNDS AS ARE LEGALLY AVAILABLE FOR SALE IN THEIR STATE.
    
 
  To be eligible for exchange, shares of the Fund must have been registered in
the shareholder's name for at least 30 days prior to an exchange. Shares of the
Fund registered in a shareholder's name for less than 30 days may only be
exchanged upon receipt of prior approval of the Adviser. Under normal
circumstances, it is the policy of the Adviser not to approve such requests.
 
  Class A Shares of Van Kampen American Capital funds that generally impose an
initial sales charge are not subject to any sales charge upon exchange into the
Fund. Class A Shares of Van Kampen American Capital funds that generally do not
impose an initial sales charge are subject to the appropriate sales charge
applicable to Class A Shares of the Fund.
 
   
  No sales charge is imposed upon the exchange of Class B Shares and Class C
Shares. The CDSC schedule and conversion schedule applicable to a Class B Share
and Class C Share acquired through the exchange privilege is determined by
reference to the Van Kampen American Capital fund from which such share
originally was purchased. The holding period of a Class B Share and Class C
Share
    
 
                                       35
<PAGE>   177
 
acquired through the exchange privilege is determined by reference to the date
such share originally was purchased from a Van Kampen American Capital fund.
 
  Exchanges of shares are sales and may result in a gain or loss for federal
income tax purposes. If the shares exchanged have been held for less than 91
days, the sales charge paid on such shares is not included in the tax basis of
the exchanged shares, but is carried over and included in the tax basis of the
shares acquired.
 
   
  A shareholder wishing to make an exchange may do so by sending a written
request to ACCESS or by contacting the telephone transaction line at (800)
421-5684 ((800) 421-2833 for the hearing impaired). A shareholder automatically
has telephone exchange privileges unless otherwise designated in the application
form accompanied by this Prospectus. The exchange will take place at the
relative net asset values of the shares next determined after receipt of such
request with adjustment for any additional sales charge. Any shares exchanged
begin earning dividends on the next business day after the exchange is affected.
Van Kampen American Capital and its subsidiaries, including ACCESS
(collectively, "VKAC"), and the Fund employ procedures considered by them to be
reasonable to confirm that instructions communicated by telephone are genuine.
Such procedures include requiring certain personal identification information
prior to acting upon telephone instructions, tape recording telephone
communications, and providing written confirmation of instructions communicated
by telephone. Exchanges are effected at the net asset value per share next
calculated after the request is received in good order with adjustment for any
additional sales charge. If reasonable procedures are employed, a shareholder
agrees that neither VKAC nor the Fund will be liable for following telephone
instructions which it reasonably believes to be genuine. VKAC and the Fund may
be liable for any losses due to unauthorized or fraudulent instructions if
reasonable procedures are not followed. If the exchanging shareholder does not
have an account in the fund whose shares are being acquired, a new account will
be established with the same registration, dividend and capital gains options
(except dividend diversification options) and broker, dealer or financial
intermediary of record as the account from which shares are exchanged, unless
otherwise specified by the shareholder. In order to establish a systematic
withdrawal plan for the new account or reinvest dividends from the new account
into another fund, an exchanging shareholder must file a specific written
request. The Fund reserves the right to reject any order to acquire shares
through exchange. In addition, the Fund may modify, restrict or terminate the
exchange privilege at any time on 60 days' notice to its shareholders of any
termination or material amendment.
    
 
   
  A prospectus of any of these mutual funds may be obtained from any broker,
dealer, financial intermediary or the Distributor. An investor considering an
exchange to one of such funds should refer to the prospectus for additional
information regarding such fund prior to investing.
    
 
  SYSTEMATIC WITHDRAWAL PLAN. Any investor whose shares in a single account
total $10,000 or more at the offering price next computed after receipt of
 
                                       36
<PAGE>   178
 
   
instructions may establish a monthly, quarterly, semi-annual or annual
withdrawal plan. Any investor whose shares in a single account total $5,000 or
more at the offering price next computed after receipt of instructions may
establish a quarterly, semi-annual or annual withdrawal plan. This plan provides
for the orderly use of the entire account, not only the income but also the
capital, if necessary. Each withdrawal constitutes a redemption of shares on
which taxable gain or loss will be recognized. The plan holder may arrange for
monthly, quarterly, semi-annual, or annual checks in any amount not less than
$25.
    
 
   
  Holders of Class B Shares and Class C Shares who establish a withdrawal plan
may redeem up to 12% annually of the shareholder's initial account balance
without incurring a contingent deferred sales charge. Initial account balance
means the amount of the shareholder's investment at the time the election to
participate in the plan is made.
    
 
  Under the plan, sufficient shares of the Fund are redeemed to provide the
amount of the periodic withdrawal payment. Dividends and capital gains
distributions on shares held under the plan are reinvested in additional shares
at the next determined net asset value. If periodic withdrawals continuously
exceed reinvested dividends and capital gains distributions, the shareholder's
original investment will be correspondingly reduced and ultimately exhausted.
Withdrawals made concurrently with purchases of additional shares ordinarily
will be disadvantageous to the shareholder because of the duplication of sales
charges. The Fund reserves the right to amend or terminate the systematic
withdrawal program on thirty days' notice to its shareholders.
 
  CHECK WRITING PRIVILEGE. Holders of Class A Shares of the Fund for which
certificates have not been issued and which are in a non-escrow status may
appoint ACCESS as agent by completing the Authorization for Redemption by Check
Form and the appropriate section of the application and returning the form and
the application to ACCESS. Once the form is properly completed, signed and
returned to the agent, a supply of checks drawn on State Street Bank and Trust
Company ("State Street Bank") will be sent to such shareholder. These checks may
be made payable by the holder of Class A Shares to the order of any person in
any amount of $100 or more.
 
  When a check is presented to State Street Bank for payment, full and
fractional Class A Shares required to cover the amount of the check are redeemed
from the shareholder's account by ACCESS at the next determined net asset value.
Check writing redemptions represent the sale of Class A Shares. Any gain or loss
realized on the sale of Class A Shares is a taxable event. See "Redemption of
Shares."
 
  Checks will not be honored for redemption of Class A Shares held less than 15
calendar days, unless such Class A Shares have been paid for by bank wire. Any
Class A Shares for which there are outstanding certificates may not be redeemed
by check. If the amount of the check is greater than the proceeds of all
uncertificated shares held in the shareholder's Class A Share account, the check
will be returned
 
                                       37
<PAGE>   179
 
   
and the shareholder may be subject to additional charges. Holders of Class A
Shares may not liquidate the entire account by means of a check. The check
writing privilege may be terminated or suspended at any time by the Fund or
State Street Bank. Retirement plans and accounts that are subject to backup
withholding are not eligible for the privilege. A "stop payment" system is not
available on these checks. See the Statement of Additional Information for
further information regarding the establishment of the privilege.
    
 
  AUTOMATED CLEARING HOUSE ("ACH") DEPOSITS. Holders of Class A Shares can use
ACH to have redemption proceeds deposited electronically into their bank
accounts. Redemptions transferred to a bank account via the ACH plan are
available to be credited to the account on the second business day following
normal payment. In order to utilize this option, the shareholder's bank must be
a member of Automated Clearing House. In addition, the shareholder must fill out
the appropriate section of the account application. The shareholder must also
include a voided check or deposit slip from the bank account into which
redemptions are to be deposited together with the completed application. Once
ACCESS has received the application and the voided check or deposit slip, such
shareholder's designated bank account, following any redemption, will be
credited with the proceeds of such redemption. Once enrolled in the ACH plan, a
shareholder may terminate participation at any time by writing ACCESS.
 
- ------------------------------------------------------------------------------
REDEMPTION OF SHARES
- ------------------------------------------------------------------------------
 
  Shareholders may redeem for cash some or all of their shares without charge by
the Fund (other than, with respect to CDSC Shares, the applicable contingent
deferred sales charge) at any time by sending a written request in proper form
directly to ACCESS, P. O. Box 418256, Kansas City, Missouri 64141-9256, by
placing the redemption request through an authorized dealer or by calling the
Fund.
 
  WRITTEN REDEMPTION REQUESTS. In the case of redemption requests sent directly
to ACCESS, the redemption request should indicate the number of shares to be
redeemed, the class designation of such shares, the account number and be signed
exactly as the shares are registered. Signatures must conform exactly to the
account registration. If the proceeds of the redemption would exceed $50,000, or
if the proceeds are not to be paid to the record owner at the record address, or
if the record address has changed within the previous 30 days, signature(s) must
be guaranteed by one of the following: a bank or trust company; a broker-dealer;
a credit union; a national securities exchange, registered securities
association or clearing agency; a savings and loan association; or a federal
savings bank. If certificates are held for the shares being redeemed, such
certificates must be endorsed for transfer or accompanied by an endorsed stock
power and sent with the redemption request. In the event the redemption is
requested by a corporation, partnership, trust, fiduciary, executor or
administrator, and the name and title of the individual(s) authorizing such
redemption is not shown in the account registration,
 
                                       38
<PAGE>   180
 
a copy of the corporate resolution or other legal documentation appointing the
authorized signer and certified within the prior 60 days must accompany the
redemption request. The redemption price is the net asset value per share next
determined after the request is received by ACCESS in proper form. Payment for
shares redeemed (less any sales charge, if applicable) will ordinarily be made
by check mailed within three business days after acceptance by ACCESS of the
request and any other necessary documents in proper order. Such payments may be
postponed or the right of redemption suspended as provided by the rules of the
SEC. If the shares to be redeemed have been recently purchased by check, ACCESS
may delay mailing a redemption check until it confirms that the purchase check
has cleared, usually a period of up to 15 days. Any gain or loss realized on the
redemption of shares is a taxable event.
 
  DEALER REDEMPTION REQUESTS. Shareholders may sell shares through their
securities dealer, who will telephone the request to the Distributor. Orders
received from dealers must be at least $500 unless transmitted via the FUNDSERV
network. The redemption price for such shares is the net asset value next
calculated after an order is received by a dealer provided such order is
transmitted to the Distributor prior to the Distributor's close of business on
such day. It is the responsibility of dealers to transmit redemption requests
received by them to the Distributor so they will be received prior to such time.
Any change in the redemption price due to failure of the Distributor to receive
a sell order prior to such time must be settled between the shareholder and
dealer. Shareholders must submit a written redemption request in proper form (as
described above under "Written Redemption Requests") to the dealer within three
business days after calling the dealer with the sell order. Payment for shares
redeemed (less any sales charge, if applicable) will ordinarily be made by check
mailed within three business days to the dealer.
 
   
  TELEPHONE REDEMPTION REQUESTS. The Fund permits redemption of shares by
telephone and for redemption proceeds to be sent to the address of record for
the account or to the bank account of record as described below. To establish
such privilege, a shareholder must complete the appropriate section of the
application accompanying this Prospectus or call the Fund at (800) 421-5666
((800) 421-2833 for the hearing impaired) to request that a copy of the
Telephone Redemption Authorization form be sent to them for completion. To
redeem shares, contact the telephone transaction line at (800) 421-5684. VKAC
and the Fund employ procedures considered by them to be reasonable to confirm
that instructions communicated by telephone are genuine. Such procedures include
requiring certain personal identification information prior to acting upon
telephone instructions, tape recording telephone communications, and providing
written confirmation of instructions communicated by telephone. If reasonable
procedures are employed, a shareholder agrees that neither VKAC nor the Fund
will be liable for following instructions which it reasonably believes to be
genuine. VKAC and the Fund may be liable for any losses due to unauthorized or
fraudulent instructions if reasonable procedures are not followed. Telephone
redemptions may not be available if the shareholder cannot reach ACCESS by
telephone, whether because all telephone
    
 
                                       39
<PAGE>   181
 
lines are busy or for any other reason; in such case, a shareholder would have
to use the Fund's other redemption procedures previously described. Requests
received by ACCESS prior to 4:00 p.m., New York time, on a regular business day
will be processed at the net asset value per share determined that day. These
privileges are available for all accounts other than retirement accounts. The
telephone redemption privilege is not available for shares represented by
certificates. If the shares to be redeemed have been recently purchased by
check, ACCESS may delay mailing a redemption check or wiring redemption proceeds
until it confirms that the purchase check has cleared, usually a period of up to
15 days. If an account has multiple owners, ACCESS may rely on the instructions
of any one owner.
 
  For redemptions authorized by telephone, amounts of $50,000 or less may be
redeemed daily if the proceeds are to be paid by check sent to the shareholders'
address of record and amounts of at least $1,000 and up to $1 million may be
redeemed daily if the proceeds are to be paid by wire sent to the shareholder's
bank account of record. The proceeds must be payable to the shareholder(s) of
record. Proceeds from redemptions to be paid by check will ordinarily be mailed
within three business days to the shareholder's address of record. Proceeds from
redemptions to be paid by wire will ordinarily be wired on the next business day
to the shareholder's bank account of record. This privilege is not available if
the address of record has been changed within 30 days prior to a telephone
redemption request. The Fund reserves the right at any time to terminate, limit
or otherwise modify this telephone redemption privilege.
 
   
  REDEMPTION UPON DISABILITY. The Fund will waive the CDSC on redemptions
following the disability of holders of Class B Shares and Class C Shares. An
individual will be considered disabled for this purpose if he or she meets the
definition thereof in Section 72(m)(7) of the Code, which in pertinent part
defines a person as disabled if such person "is unable to engage in any
substantial gainful activity by reason of any medically determinable physical or
mental impairment which can be expected to result in death or to be of
long-continued and indefinite duration." While the Fund does not specifically
adopt the balance of the Code's definition which pertains to furnishing the
Secretary of Treasury with such proof as he or she may require, the Distributor
will require satisfactory proof of disability before it determines to waive the
CDSC on Class B Shares and Class C Shares.
    
 
   
  In cases of disability, the CDSCs on Class B Shares and Class C Shares will be
waived where the disabled person is either an individual shareholder or owns the
shares as a joint tenant with right of survivorship or is the beneficial owner
of a custodial or fiduciary account, and where the redemption is made within one
year of the initial determination of disability. This waiver of the CDSC on
Class B Shares and Class C Shares applies to a total or partial redemption, but
only to redemptions of shares held at the time of the initial determination of
disability.
    
 
                                       40
<PAGE>   182
 
   
  GENERAL REDEMPTION INFORMATION. The Fund may redeem any shareholder account
with a net asset value on the date of the notice of redemption less than the
minimum investment as specified by the Trustees. At least 60 days advance
written notice of any such involuntary redemption is required and the
shareholder is given an opportunity to purchase the required value of additional
shares at the next determined net asset value without sales charge. Any
applicable CDSC will be deducted from the proceeds of this redemption. Any
involuntary redemption may only occur if the shareholder account is less than
the minimum investment due to shareholder redemptions.
    
 
   
  REINSTATEMENT PRIVILEGE. Holders of Class A Shares or Class B Shares who have
redeemed shares of the Fund may reinstate any portion or all of the net proceeds
of such redemption in Class A Shares of the Fund. Holders of Class C Shares who
have redeemed shares of the Fund may reinstate any portion or all of the net
proceeds of such redemption in Class C Shares of the Fund with credit given for
any CDSC paid upon such redemption. Such reinstatement is made at the net asset
value (without sales charge except as described under "Shareholder Services --
Exchange Privilege") next determined after the order is received, which must be
within 180 days after the date of the redemption. See "Purchase of
Shares -- Waiver of Contingent Deferred Sales Charge." Reinstatement at net
asset value is also offered to participants in those eligible retirement plans
held or administered by Van Kampen American Capital Trust Company for repayment
of principal (and interest) on their borrowings on such plans.

DISTRIBUTION AND SERVICE PLANS
    
- ------------------------------------------------------------------------------
 
  The Fund has adopted a distribution plan (the "Distribution Plan") with
respect to each class of its shares pursuant to Rule 12b-1 under the 1940 Act.
The Fund also has adopted a service plan (the "Service Plan") with respect to
each class of its shares. The Distribution Plan and the Service Plan provide
that the Fund may spend a portion of the Fund's average daily net assets
attributable to each class of shares in connection with distribution of the
respective class of shares and in connection with the provision of ongoing
services to shareholders of each class. The Distribution Plan and the Service
Plan are being implemented through an agreement with the Distributor and
sub-agreements between the Distributor and brokers, dealers and financial
intermediaries (collectively, "Selling Agreements") that may provide for their
customers or clients certain services or assistance.
 
   
  CLASS A SHARES. The Fund may spend an aggregate amount up to 0.25% per year of
the average daily net assets attributable to the Class A Shares of the Fund
pursuant to the Distribution Plan and Service Plan. From such amount, the Fund
may spend up to 0.25% per year of the Fund's average daily net assets
attributable to the Class A Shares pursuant to the Service Plan in connection
with the ongoing provision of services to holders of such shares by the
Distributor and by brokers, dealers or financial intermediaries and in
connection with the maintenance of such
    
 
                                       41
<PAGE>   183
 
   
shareholders' accounts. The Fund pays the Distributor the lesser of the balance
of the 0.25% not paid to such brokers, dealers or financial intermediaries or
the amount of the Distributor's actual distribution-related expense.
    
 
  CLASS B SHARES. The Fund may spend up to 0.75% per year of the average daily
net assets attributable to the Class B Shares of the Fund pursuant to the
Distribution Plan. In addition, the Fund may spend up to 0.25% per year of the
Fund's average daily net assets attributable to the Class B Shares pursuant to
the Service Plan in connection with the ongoing provision of services to holders
of such shares by the Distributor and by brokers, dealers or financial
intermediaries and in connection with the maintenance of such shareholders'
accounts.
 
   
  CLASS C SHARES. The Fund may spend up to 0.75% per year of the average daily
net assets attributable to the Class C Shares of the Fund pursuant to the
Distribution Plan. From such amount, the Fund, or the Distributor as agent for
the Fund, pays brokers, dealers or financial intermediaries in connection with
the distribution of the Class C Shares up to 0.75% of the Fund's average daily
net assets attributable to Class C Shares maintained in the Fund more than one
year by such broker's, dealer's or financial intermediary's customers. The Fund
pays the Distributor the lesser of the balance of 0.75% not paid to such
brokers, dealers or financial intermediaries or the amount of the Distributor's
actual distribution-related expense attributable to the Class C Shares. In
addition, the Fund may spend up to 0.25% per year of the Fund's average daily
net assets attributable to the Class C Shares pursuant to the Service Plan in
connection with the ongoing provision of services to holders of such shares by
the Distributor and by brokers, dealers or financial intermediaries and in
connection with the maintenance of such shareholders' accounts.
    
 
  OTHER INFORMATION. Amounts payable to the Distributor with respect to the
Class A Shares under the Distribution Plan in a given year may not fully
reimburse the Distributor for its actual distribution-related expenses during
such year. In such event, with respect to the Class A Shares, there is no
carryover of such reimbursement obligations to succeeding years.
 
   
  The Distributor's actual expenses with respect to a class of CDSC Shares (for
purposes of this section, excluding any Class A Shares that may be subject to a
CDSC) for any given year may exceed the amounts payable to the Distributor with
respect to such class of CDSC Shares under the Distribution Plan, the Service
Plan and payments received pursuant to the CDSC. In such event, with respect to
any such class of CDSC Shares, any unreimbursed expenses will be carried forward
and paid by the Fund (up to the amount of the actual expenses incurred) in
future years so long as such Distribution Plan is in effect. Except as mandated
by applicable law, the Fund does not impose any limit with respect to the number
of years into the future that such unreimbursed expenses may be carried forward
(on a Fund level basis). Because such expenses are accounted on a Fund level
basis, in periods of extreme net asset value fluctuation such amounts with
respect to a particular CDSC Share may be greater or less than the amount of the
initial commission (including
    
 
                                       42
<PAGE>   184
 
   
carrying cost) paid by the Distributor with respect to such CDSC Share. In such
circumstances, a shareholder of such CDSC Share may be deemed to incur expenses
attributable to other shareholders of such class. As of December 31, 1996, there
were $4,213,746 and $51,726 of unreimbursed distribution expenses with respect
to Class B Shares and Class C Shares, respectively, representing 2.00% and 0.40%
of the Fund's net assets attributable to Class B Shares and Class C Shares,
respectively. If the Distribution Plan was terminated or not continued, the Fund
would not be contractually obligated to pay the Distributor for any expenses not
previously reimbursed by the Fund or recovered through CDSCs.
    
 
   
  Because the Fund is a series of the Trust, amounts paid to the Distributor as
reimbursement for expenses of one series of the Trust may indirectly benefit the
other funds which are series of the Trust. The Distributor will endeavor to
allocate such expenses among such funds in an equitable manner. The Distributor
will not use the proceeds from the CDSC applicable to a particular class of
shares to defray distribution-related expenses attributable to any other class
of shares. Various federal and state laws prohibit national banks and some
state-chartered commercial banks from underwriting or dealing in the Fund's
shares. In addition, state securities laws on this issue may differ from the
interpretations of federal law, and banks and financial institutions may be
required to register as dealers pursuant to state law. In the unlikely event
that a court were to find that these laws prevent such banks from providing such
services described above, the Fund would seek alternate providers and expects
that shareholders would not experience any disadvantage.
    
 
- ------------------------------------------------------------------------------
DISTRIBUTIONS FROM THE FUND
- ------------------------------------------------------------------------------
 
  The Fund's present policy, which may be changed at any time by the Board of
Trustees, is to declare daily and pay monthly distributions of all or
substantially all net investment income of the Fund. Net investment income
consists of all interest income and dividends, less all expenses of the Fund
attributable to the class of shares in question. Net short-term capital gains,
if any, may be distributed throughout the year. Expenses of the Fund are accrued
each day. Net realized long-term capital gains, if any, are expected to be
distributed, to the extent permitted by applicable law, to shareholders at least
annually. Distributions cannot be assured, and the amount of each monthly
distribution may vary.
 
  Distributions with respect to each class of shares will be calculated in the
same manner on the same day and will be in the same amount, except that the
different distribution and service fees and any incremental administrative
expenses relating to each class of shares will be borne exclusively by the
respective class and may cause the distributions relating to the different
classes of shares to differ. Generally, distributions with respect to a class of
shares subject to a higher distribution fee, service fee, or where applicable,
the conversion feature will be lower than distributions with respect to a class
of shares subject to a lower distribution fee, service fee, or not subject to
the conversion feature.

  Investors will be entitled to begin receiving dividends on their shares on the
business day after ACCESS receives payments for such shares. However, shares
become entitled to dividends on the day ACCESS receives payment for the shares
either through a fed wire or NSCC settlement. Shares remain entitled to
dividends through the day such shares are processed for payment on redemption.
    
 
  Distribution checks may be sent to parties other than the shareholder in whose
name the account is registered. Persons wishing to utilize this service should
complete the appropriate section of the account application accompanying this
Prospectus or available from Van Kampen American Capital Funds, c/o ACCESS, P.O.
Box 418256, Kansas City, MO 64141-9256. After ACCESS receives this completed
form, distribution checks will be sent to the bank or other person so designated
by such shareholder.
 
   
  PURCHASE OF ADDITIONAL SHARES WITH DISTRIBUTIONS.  The Fund will automatically
credit monthly distributions and any annual net long-term capital gain
distributions to a shareholder's account in additional shares of the Fund valued
at net asset value, without a sales charge. Unless a shareholder instructs
otherwise, the reinvestment plan is automatic. This instruction may be made by
telephone by calling (800) 421-5666 ((800) 421-2833 for the hearing impaired) or
in writing to ACCESS. See "Shareholder Services -- Reinvestment Plan."
    
 
- ------------------------------------------------------------------------------
TAX STATUS
- ------------------------------------------------------------------------------
 
   
  FEDERAL INCOME TAXATION.  The Fund has qualified and intends to continue to
qualify each year and to elect to be treated as a regulated investment company
under Subchapter M of the Code. To qualify as a regulated investment company,
the Fund must comply with certain requirements of the Code relating to, among
other things, the source of its income and diversification of its assets.
    
 
   
  If the Fund so qualifies and distributes each year to its shareholders at
least 90% of its net investment income (including tax-exempt interest, taxable
income and net short-term capital gain, but not net capital gains, which are the
excess of net long-term capital gains over net short-term capital losses), it
will not be required to pay federal income taxes on any income distributed to
shareholders. The Fund intends to distribute at least the minimum amount of net
investment income necessary to satisfy the 90% distribution requirement. The
Fund will not be subject to federal income tax on any net capital gains
distributed to shareholders.
    
 
   
  In order to avoid a 4% excise tax, the Fund will be required to distribute, by
December 31 of each year, at least 98% of its ordinary income (not including
tax-exempt income) for such year and at least 98% of its capital gain net income
(the latter of which generally is computed on the basis of the one-year period
ending on October 31 of such year), plus any amounts that were not distributed
in previous taxable years. For purposes of the excise tax, any ordinary income
or capital gain
    
 
                                       44
<PAGE>   186
 
   
net income retained by, and subject to federal income tax in the hands of, the
Fund will be treated as having been distributed.
    
 
   
  If the Fund failed to qualify as a regulated investment company or failed to
satisfy the 90% distribution requirement in any taxable year, the Fund would be
taxed as an ordinary corporation on its taxable income (even if such income were
distributed to its shareholders) and all distributions out of earnings and
profits would be taxed to shareholders as ordinary income. To qualify again as a
regulated investment company in a subsequent year, the Fund may be required to
pay an interest charge on 50% of its earnings and profits attributable to
non-regulated investment company years and would be required to distribute such
earnings and profits to shareholders (less any interest charge). In addition, if
the Fund failed to qualify as a regulated investment company for its first
taxable year or, if immediately after qualifying as a regulated investment
company for any taxable year, it failed to qualify for a period greater than one
taxable year, the Fund would be required to recognize any net built-in gains
(the excess of aggregate gains, including items of income, over aggregate losses
that would have been realized if it had been liquidated) in order to qualify as
a regulated investment company in a subsequent year.
    
 
   
  Some of the Fund's investment practices are subject to special provisions of
the Code that, among other things, may defer the use of certain losses of the
Fund and affect the holding period of the securities held by the Fund and the
character of the gains or losses realized by the Fund. These provisions may also
require the Fund to mark-to-market some of the positions in its portfolio (i.e.,
treat them as if they were sold for fair market value at the end of the
tax-year), which may cause the Fund to recognize income without receiving cash
with which to make distributions in amounts necessary to satisfy the 90%
distribution requirement and the distribution requirements for avoiding income
and excise taxes. The Fund will monitor its transactions and may make certain
tax elections in order to mitigate the effect of these rules and prevent
disqualification of the Fund as a regulated investment company.
    
 
   
  The Fund's ability to dispose of portfolio securities may be limited by the
requirement for qualification as a regulated investment company that less than
30% of the Fund's annual gross income be derived from the disposition of
securities held for less than three months.
    
 
   
  Investments of the Fund in securities issued at a discount or providing for
deferred interest or payment of interest in kind are subject to special tax
rules that will affect the amount, timing and character of distributions to
shareholders. For example, with respect to securities issued at a discount, the
Fund will be required to accrue as income each year a portion of the discount
and to distribute such income each year in order to maintain its qualification
as a regulated investment company and to avoid income and excise taxes. In order
to generate sufficient cash to make distributions necessary to satisfy the 90%
distribution requirement and to avoid income and excise taxes, the Fund may have
to dispose of securities that it would
    
 
                                       45
<PAGE>   187
 
   
otherwise have continued to hold. A portion of the discount relating to certain
stripped tax-exempt obligations may constitute taxable income when distributed
to shareholders.
    
 
   
  DISTRIBUTIONS.  The Fund intends to invest in sufficient tax-exempt municipal
securities to permit payment of "exempt-interest dividends" (as defined in the
Code). Dividends paid by the Fund from the net tax-exempt interest earned from
municipal securities qualify as exempt-interest dividends if, at the close of
each quarter of its taxable year, at least 50% of the value of the total assets
of the Fund consists of municipal securities.
    
 
   
  The Tax Reform Act of 1986 (the "Tax Reform Act") may have an adverse impact
upon the Fund and its shareholders. The Tax Reform Act imposed new limitations
on the use and investment of the proceeds of state and local government bonds
and other funds, which limitations must be satisfied in order to maintain the
exclusion from gross income for interest on such bonds. The provisions of the
Tax Reform Act generally apply to bonds issued after August 15, 1986. In light
of these requirements, bond counsel qualify their opinions as to the federal tax
status of bonds issued after August 15, 1986 by making them contingent on the
issuer's future compliance with these limitations. Any failure on the part of an
issuer to comply could cause the interest on its bonds to become taxable to
investors retroactive to the date the bonds were issued.
    
 
   
  Except as provided below, exempt-interest dividends paid to shareholders
generally are not includable in the shareholders' gross income for federal
income tax purposes. The percentage of the total dividends paid by the Fund
during any taxable year that qualify as exempt-interest dividends will be the
same for all shareholders of the Fund receiving dividends during such year.
    
 
   
  The Tax Reform Act also makes interest on certain "private-activity bonds" an
item of tax preference subject to the alternative minimum tax on individuals and
corporations. The Fund invests a portion of its assets in municipal securities
subject to this provision so that a portion of its exempt-interest dividends is
an item of tax preference to the extent such dividends represent interest
received from these private-activity bonds. Accordingly, investment in the Fund
could cause shareholders to be subject to (or result in an increased liability
under) the alternative minimum tax. The Tax Reform Act also imposed per capita
volume limitations on certain private-activity bonds which could limit the
amount of such bonds available for investment by the Fund.
    
 
   
  Exempt-interest dividends are included in determining what portion, if any, of
a person's social security and railroad retirement benefits will be includable
in gross income subject to federal income tax.
    
 
   
  Although exempt-interest dividends generally may be treated by Fund
shareholders as items of interest excluded from their gross income, each
shareholder is advised to consult his tax adviser with respect to whether
exempt-interest dividends retain this exclusion if the purchaser would be
treated as a "substantial user" (or a
    
 
                                       46
<PAGE>   188
 
   
"related person" of a substantial user) of the facilities financed with respect
to any of the tax-exempt obligations held by the Fund, or by the Trust if it is
required to qualify as a regulated investment company as described below.
"Substantial user" is defined under U.S. Treasury Regulations to include a
non-exempt person who regularly uses in his trade or business a part of any
facilities financed with the tax-exempt obligations and whose gross revenues
derived from such facilities exceed five percent of the total revenues derived
from the facilities by all users, or who occupies more than 5% of the useable
area of the facilities or for whom the facilities or a part thereof were
specifically constructed, reconstructed or acquired. Examples of "related
persons" include certain related natural persons, affiliated corporations, a
partnership and its partners and an S corporation and its shareholders.
    
 
   
  The Omnibus Budget Reconciliation Act of 1993 included certain provisions that
requires gains on dispositions of tax-exempt securities purchased at a market
discount be treated as ordinary income to the extent of the accrued market
discount, if the securities are acquired after April 30, 1993. Such securities
were exempt from the market discount rules under prior law. Interest on
indebtedness incurred or continued by a shareholder to purchase or carry shares
of the Fund is not deductible for federal income tax purposes if the Fund
distributes exempt-interest dividends during the shareholder's taxable year. If
a shareholder receives an exempt-interest dividend with respect to any shares
and such shares are held for six months or less, any short-term capital loss on
the sale or exchange of the shares will be disallowed to the extent of the
amount of such exempt-interest dividend.
    
 
   
  While the Fund expects that a major portion of its net investment income will
constitute tax-exempt interest, a significant portion may consist of investment
company taxable income. Distributions of the Fund's net investment company
taxable income are taxable to shareholders as ordinary income to the extent of
the Fund's earnings and profits, whether paid in cash or reinvested in
additional shares. Distributions of the Fund's net capital gains ("capital gains
dividends"), if any, are taxable to shareholders as long-term capital gains
regardless of the length of time shares of the Fund have been held by such
shareholders. Interest on indebtedness which is incurred to purchase or carry
shares of a mutual fund which distributes exempt-interest dividends during the
year is not deductible for federal income tax purposes. Distributions in excess
of the Fund's earnings and profits will first reduce the adjusted tax basis of a
holder's shares and, after such adjusted tax basis is reduced to zero, will
constitute capital gains to such holder (assuming such shares are held as a
capital asset). Tax-exempt shareholders not subject to federal income tax on
their income generally will not be taxed on distributions from the Fund.
    
 
   
  Shareholders receiving distributions in the form of additional shares issued
by the Fund will be treated for federal income tax purposes as receiving a
distribution in an amount equal to the fair market value of the shares received,
determined as of the distribution date. The basis of such shares will equal the
fair market value on the distribution date.
    
 
                                       47
<PAGE>   189
 
   
  The Fund will inform shareholders of the source and tax status of all
distributions promptly after the close of each calendar year. The aggregate
amount of dividends so designated cannot exceed, however, the amount of interest
exempt from tax under Section 103 of the Code received by the Fund during the
year over any amounts disallowed as deductions under Sections 265 and 171(a)(2)
of the Code. Since the percentage of dividends which are "exempt-interest"
dividends is determined on an average annual method for the fiscal year, the
percentage of income designated as tax-exempt for any particular dividend may be
substantially different from the percentage of the Fund's income that was tax
exempt during the period covered by the dividend, Fund distributions generally
will not qualify for the dividends received deduction for corporations.
    
 
   
  Although dividends generally will be treated as distributed when paid,
dividends declared in October, November or December, payable to shareholders of
record on a specified date in such month and paid during January of the
following year will be treated as having been distributed by the Fund and
received by the shareholders on the December 31 prior to the date of payment. In
addition, certain other distributions made after the close of a taxable year of
the Fund may be "spilled back" and treated as paid by the Fund (except for
purposes of the 4% excise tax) during such taxable year. In such case,
shareholders will be treated as having received such dividends in the taxable
year in which the distribution was actually made.
    
 
   
  The Fund is required, in certain circumstances, to withhold 31% of dividends
and certain other payments, including redemptions, paid to shareholders who do
not furnish to the Fund their correct taxpayer identification number (in the
case of individuals, their social security number) and certain required
certifications or who are otherwise subject to backup withholding.
    
 
   
  SALE OF SHARES.  The sale of shares (including transfers in connection with a
redemption or repurchase of shares) will be a taxable transaction for federal
income tax purposes. Selling shareholders will generally recognize gain or loss
in an amount equal to the difference between their adjusted tax basis in the
shares and the amount received. If such shares are held as a capital asset, the
gain or loss will be a capital gain or loss and will be long-term if such shares
have been held for more than one year. Any loss realized upon a taxable
disposition of shares held for six months or less will be treated as a long-term
capital loss to the extent of any capital gains dividends received with respect
to such shares. For purposes of determining whether shares have been held for
six months or less, the holding period is suspended for any periods during which
the shareholder's risk of loss is diminished as a result of holding one or more
other positions in substantially similar or related property or through certain
options or short sales.
    
 
   
  STATE AND LOCAL TAXES.  The exemption of interest income for federal income
tax purposes may not result in similar exemptions under the laws of a particular
state or local taxing authority. Income distributions may be taxable to
shareholders under state or local law as dividend income even though a portion
of such distributions may be derived from interest on tax-exempt obligations
which, if
    
 
                                       48
<PAGE>   190
 
   
realized directly, would be exempt from such income taxes. It is recommended
that investors consult their tax advisers for information in this regard. The
Fund will report annually to its shareholders the percentage and source, on a
state-by-state basis, of interest income earned on municipal securities received
by the Fund during the preceding calendar year. Dividends and distributions paid
by the Fund from sources other than tax-exempt interest are generally subject to
taxation at the state and local levels.
    
 
   
  GENERAL.  The federal, state and local income tax discussion set forth above
is for general information only. Prospective investors should consult their
advisors regarding the specific federal tax consequences of holding and
disposing of shares, as well as the effects of state, local and foreign tax law
and any proposed tax law changes.

FUND PERFORMANCE
- ------------------------------------------------------------------------------
 
   
  From time to time advertisements and other sales materials for the Fund may
include information concerning the historical performance of the Fund. Any such
information will include the average total return of the Fund calculated on a
compounded basis for specified periods of time. Such advertisements and sales
material may also include a yield quotation as of a current period. In each
case, such total return and yield information, if any, will be calculated
pursuant to rules established by the SEC and will be computed separately for
each class of the Fund's shares. In lieu of or in addition to total return and
yield calculations, such information may include performance rankings and
similar information from independent organizations such as Lipper Analytical
Services, Inc. or nationally recognized financial publications.
    
 
   
  From time to time, the Fund may include in its sales literature and
shareholder reports a quotation of the current "distribution rate" for each
class of shares of the Fund. Distribution rate is a measure of the level of
income and short-term capital gain dividends, if any, distributed for a
specified period. Distribution rate is determined by annualizing the
distributions per share for a stated period and dividing the result by the
public offering price for the same period. It differs from yield, which is a
measure of the income actually earned by the Fund's investments, and from total
return, which is a measure of the income actually earned by, plus the effect of
any realized and unrealized appreciation or depreciation of such investments
during a stated period. Distribution rate is, therefore, not intended to be a
complete measure of the Fund's performance. Distribution rate may sometimes be
greater than yield since, for instance, it may not include the effect of
amortization of bond premiums, and may include non-recurring short-term capital
gains and premiums from futures transactions engaged in by the Fund.
Distribution rates will be computed separately for each class of the Fund's
shares.
    
 
  From time to time, the Fund may compare its performance to certain securities
and unmanaged indices which may have different risk/reward characteristics than
the Fund. Such characteristics may include, but are not limited to, tax
features,
 
                                       49
<PAGE>   191
 
guarantees, insurance and the fluctuation of principal and/or return. In
addition, from time to time, the Fund may utilize sales literature that includes
hypotheticals.

Annual Report and the Fund's Statement of Additional Information, each of which
can be obtained without charge by calling (800) 421-5666 ((800) 421-2833 for the

- ------------------------------------------------------------------------------
DESCRIPTION OF SHARES OF THE FUND
- ------------------------------------------------------------------------------
 
  The Fund is a series of the Van Kampen American Capital Tax Free Trust, a
Delaware business trust organized as of May 10, 1995 (the "Trust"). The Fund was
originally organized as a sub-trust of a Massachusetts business trust by a
Declaration of Trust dated August 15, 1985, under the name Van Kampen Merritt
Municipal Income Fund and was reorganized as a series of the Trust on July 31,
1995. Shares of the Trust entitle their holders to one vote per share; however,
separate votes are taken by each series on matters affecting an individual
series.
 
   
  The authorized capitalization of the Fund consists of an unlimited number of
shares of beneficial interest, $0.01 par value, divided into three classes,
designated Class A Shares, Class B Shares and Class C Shares. Each class of
shares represents an interest in the same assets of the Fund and are identical
in all respects except that each class bears certain distribution expenses and
has exclusive voting rights with respect to its distribution fee. See
"Distribution and Service Plans."
    
 
   
  The Fund is permitted to issue an unlimited number of classes of shares. Each
class of shares is equal as to earnings, assets and voting privileges, except as
noted above, and each class bears the expenses related to the distribution of
its shares. There are no conversion, preemptive or other subscription rights,
except with respect to the conversion of Class B Shares and certain Class C
Shares into Class A Shares as described above. In the event of liquidation, each
of the shares of the Fund is entitled to its portion of all of the Fund's net
assets after all debt and expenses of the Fund have been paid. Since Class B
Shares and Class C Shares pay higher distribution expenses, the liquidation
proceeds to holders of Class B Shares and Class C Shares are likely to be lower
than to other shareholders.
    
 
  The Trust does not contemplate holding regular meetings of shareholders to
elect Trustees or otherwise. However, the holders of 10% or more of the
outstanding shares may by written request require a meeting to consider the
removal of Trustees by a vote of two-thirds of the shares then outstanding cast
in person or by proxy at such meeting. The Trust will assist such holders in
communicating with other shareholders of the Fund to the extent required by the
1940 Act. More detailed information concerning the Trust is set forth in the
Statement of Additional Information.

ADDITIONAL INFORMATION
- ------------------------------------------------------------------------------
 
  This Prospectus and the Statement of Additional Information do not contain all
the information set forth in the Registration Statement filed by the Fund with
the SEC under the Securities Act of 1933. Copies of the Registration Statement
may be obtained at a reasonable charge from the SEC or may be examined, without

                               PROSPECTUS SUMMARY
- ------------------------------------------------------------------------------
 
THE FUND.  Van Kampen American Capital Intermediate Term Municipal Income Fund
(the "Fund") is a separate diversified series of Van Kampen American Capital Tax
Free Trust (the "Trust"), which is an open-end management investment company
organized as a Delaware business trust. See "The Fund."
 
MINIMUM PURCHASE.  $500 minimum initial investment for each class of shares and
$25 minimum subsequent investment for each class of shares (or less as described
under "Purchase of Shares").
 
INVESTMENT OBJECTIVE.  The Fund's investment objective is to seek a high level
of current income exempt from federal income tax, consistent with preservation
of capital.
 
INVESTMENT POLICIES.  The Fund will seek to achieve its investment objective by
investing at least 65% of its total assets in a diversified portfolio of
municipal securities rated investment grade at the time of investment.
Investment grade securities are securities rated BBB or higher by Standard &
Poor's Ratings Group ("S&P") or Baa or higher by Moody's Investors Service, Inc.
("Moody's") or comparably rated by any other nationally recognized statistical
ratings organization ("NRSRO"). The Fund may invest the remainder of its total
assets in municipal securities rated below investment grade and in unrated
municipal securities believed by the Fund's investment adviser to be of
comparable quality, which involve special risk considerations. Securities rated
below investment grade and unrated securities determined by the Fund's
investment adviser to be of comparable quality commonly are referred to as "junk
bonds". Under normal market conditions, the Fund anticipates that it will limit
the dollar-weighted average life of its portfolio to between three and ten
years. There is no assurance that the Fund will achieve its investment
objective. See "Investment Objective and Policies."
 
  Municipal securities in which the Fund may invest include fixed and variable
rate securities, municipal notes, municipal leases, tax exempt commercial paper,
custodial receipts, participation certificates and derivative municipal
securities the terms of which include elements of, or are similar in effect to,
certain Strategic Transactions (as defined herein) in which the Fund may engage.
The Fund may invest up to 15% of its total assets in derivative variable rate
securities such as inverse floaters, whose rates vary inversely with changes in
market rates of interest or range or capped floaters, whose rates are subject to
periodic or lifetime caps. The net asset value per share of the Fund may
increase or decrease depending on changes in interest rates and other factors
affecting the municipal securities markets. See "Municipal Securities."
 
INVESTMENT PRACTICES.  The Fund also may use various investment techniques
including engaging in Strategic Transactions and entering into when-issued or
delayed delivery transactions. Such transactions entail certain risks. See
"Municipal Securities" and "Investment Practices." The Fund may invest an
unlimited portion
 
                                        4
<PAGE>   199
 
of its assets in municipal securities that pay interest that is subject to the
federal alternative minimum tax. The Fund may not be a suitable investment for
investors who are already subject to the federal alternative minimum tax or who
would become subject to the federal alternative minimum tax as a result of an
investment in the Fund. See "Tax Status."
 
INVESTMENT RESULTS.  The investment results of the Fund are shown in the table
of "Financial Highlights."
 
ALTERNATIVE SALES ARRANGEMENTS.  The Alternative Sales Arrangements permit an
investor to choose the method of purchasing shares that is more beneficial to
the investor, taking into account the amount of the purchase, the length of time
the investor expects to hold the shares and other circumstances. Investors
should consider such factors together with the amount of sales charges and
accumulated distribution and service fees with respect to each class of shares
that may be incurred over the anticipated duration of their investment in the
Fund. To assist investors in making this determination, the table under the
caption "Annual Fund Operating Expenses and Example" sets forth examples of the
charges applicable to each class of shares.
 
  The Fund offers three classes of shares which may be purchased at a price
equal to their net asset value per share, plus a sales charge which, at the
election of the investor, may be imposed either (i) at the time of the purchase
("Class A Shares") or (ii) on a contingent deferred basis (Class A Share
accounts over $1 million, "Class B Shares" and "Class C Shares"). Class A Share
accounts over $1 million or otherwise subject to a contingent deferred sales
charge ("CDSC"), Class B Shares and Class C Shares sometimes are referred to
herein collectively as "CDSC Shares".
 
  Class A Shares. Class A Shares are subject to an initial sales charge equal to
3.25% of the public offering price (3.36% of the net amount invested), reduced
on investments of $25,000 or more. Class A Shares are subject to ongoing
distribution and service fees at an aggregate annual rate of up to 0.25% of the
Fund's average daily net assets attributable to the Class A Shares. Certain
purchases of Class A Shares qualify for reduced or no initial sales charges and
may be subject to a CDSC.
 
   
  Class B Shares. Class B Shares do not incur a sales charge when they are
purchased, but generally are subject to a sales charge if redeemed within four
years of purchase. Class B Shares are subject to a CDSC equal to 3.00% of the
lesser of the then current net asset value or the original purchase price on
Class B Shares redeemed during the first year after purchase, which charge is
reduced each year thereafter. Class B Shares are subject to ongoing distribution
and service fees at an aggregate annual rate of up to 1.00% of the Fund's
average daily net assets attributable to the Class B Shares. Class B Shares
automatically convert to Class A Shares eight years after the end of the
calendar month in which the investor's order to purchase was accepted.
    
 
                                        5
<PAGE>   200
 
   
  Class C Shares. Class C Shares do not incur a sales charge when they are
purchased, but are subject to a sales charge if redeemed within the first year
after purchase. Class C Shares are subject to a CDSC equal to 1.00% of the
lesser of the then current net asset value or the original purchase price on
Class C Shares redeemed during the first year after purchase. Class C Shares are
subject to ongoing distribution and service fees at an aggregate annual rate of
up to 1.00% of the Fund's average daily net assets attributable to the Class C
Shares.
    
 
REDEMPTION.  Class A Shares may be redeemed at net asset value, without charge,
subject to conditions set forth herein. CDSC Shares may be redeemed at net asset
value less a deferred sales charge which will vary among each class of CDSC
Shares and with the length of time a redeeming shareholder has owned such
shares. CDSC Shares redeemed after the expiration of the CDSC period applicable
to the respective class of CDSC Shares will not be subject to a deferred sales
charge. See "Redemption of Shares."
 
   
INVESTMENT ADVISER.  Van Kampen American Capital Investment Advisory Corp. (the
"Adviser"), is the Fund's investment adviser.
    
 
   
DISTRIBUTOR.  Van Kampen American Capital Distributors, Inc. (the
"Distributor"), distributes the Fund's shares.
    
 
DISTRIBUTIONS FROM THE FUND.  Distributions from net investment income are
declared daily and paid monthly; net realized capital gains, if any, are
distributed annually. Distributions with respect to each class of shares will be
calculated in the same manner on the same day and will be in the same amount
except that the different distribution and service fees and administrative
expenses relating to each class of shares will be borne exclusively by that
class. See "Distributions from the Fund."
 
   
  The foregoing is qualified in its entirety by reference to the more detailed
              information appearing elsewhere in this Prospectus.

(1) Expenses include an assumption of "Other expenses" of $64,338 by the
   Adviser. If the Adviser did not waive expenses for the fiscal year ending
   December 31, 1996, the "Other expenses" would have been 0.99% for Class A
   Shares, 1.00% for Class B Shares and 1.00% for Class C Shares and "Total
   expenses" would have been 1.74% for Class A Shares, 2.50% for Class B Shares
   and 2.50% for Class C Shares.
    
 
   
(2) Includes a service fee of up to 0.25% (as a percentage of net asset value)
   paid by the Fund as compensation for ongoing services rendered to investors.
   With respect to each class of shares, amounts in excess of 0.25% represent an
   asset based sales charge. The asset based sales charge with respect to Class
   C Shares includes 0.75% (as a percentage of net asset value) paid to
   investors' broker-dealers as sales compensation.

expected to decrease. Accordingly, it is unlikely that future expenses as
projected will remain consistent with those determined based on the "Annual Fund
Operating Expenses" table. The ten year amount with respect to Class B Shares of
the Fund reflects the lower aggregate 12b-1 and service fees applicable to such
shares after conversion to Class A Shares. Class B Shares acquired through the
exchange privilege are subject to the deferred sales charge schedule relating to
the Class B Shares of the Fund from which the purchase of Class B Shares was
originally made. Accordingly, future expenses as projected could be higher than
those determined in the above table if the investor's Class B Shares were
exchanged from a fund with a higher contingent deferred sales charge. THE
INFORMATION CONTAINED IN THE ABOVE TABLE SHOULD NOT BE CONSIDERED A
REPRESENTATION OF PAST OR FUTURE EXPENSES AND ACTUAL EXPENSES MAY BE GREATER
THAN OR LESS THAN THOSE SHOWN. For a more complete description of such costs and
expenses, see "Purchase of Shares," "Redemption of Shares," "Investment Advisory
Services" and "Distribution and Service Plans."

THE FUND
- ------------------------------------------------------------------------------
 
  Van Kampen American Capital Intermediate Term Municipal Income Fund (the
"Fund") is a separate diversified series of Van Kampen American Capital Tax Free
Trust (the "Trust"), which is an open-end management investment company,
commonly known as a "mutual fund," organized as a Delaware business trust.
Mutual funds sell their shares to investors and invest the proceeds in a
portfolio of securities. A mutual fund allows investors to pool their money with
that of other investors in order to obtain professional investment management.
Mutual funds generally make it possible for investors to obtain greater
diversification of their investments and to simplify their recordkeeping.
 
  Van Kampen American Capital Investment Advisory Corp. (the "Adviser") provides

INVESTMENT OBJECTIVE AND POLICIES
- ------------------------------------------------------------------------------
 
  The investment objective of the Fund is to seek a high level of current income
exempt from federal income tax, consistent with preservation of capital. The
Fund's investment objective may not be changed without shareholder approval. The
Fund will seek to achieve its investment objective by investing at least 65% of
its total assets in a diversified portfolio of municipal securities rated
investment grade at the time of investment. The Fund may invest the remainder of
its total assets in municipal securities rated below investment grade and in
unrated municipal securities believed by the Fund's investment adviser to be
comparable quality, which involve special risk considerations. Securities rated
below investment grade and unrated securities determined by the Fund's
investment adviser to be of comparable quality commonly are referred to as "junk
bonds". Under normal market conditions, the Fund anticipates that it will limit
the dollar-weighted average life of its portfolio to between three and ten
years. There is no limit with respect to the expected life or stated maturity of
individual municipal securities in which the Fund may invest. The Fund's
policies with respect to ratings and portfolio life are not fundamental
policies, and thus may be changed by the Trustees without shareholder approval.
See "Municipal Securities."
 
  The Fund intends to invest at least 65% of its total assets in municipal
securities rated investment grade at the time of investment. Investment grade
securities are securities rated BBB or higher by Standard & Poor's Ratings Group
("S&P") or Baa or higher by Moody's Investors Service, Inc. ("Moody's") or
comparably rated by any other nationally recognized statistical rating
organization ("NRSRO") in the case of long-term obligations, and have equivalent
ratings in the case of short-term
 
                                       11
<PAGE>   206
 
obligations. Securities rated BBB by S&P are regarded by S&P as having an
adequate capacity to pay interest and repay principal. Whereas such securities
normally exhibit adequate protection parameters, adverse economic conditions or
changing circumstances are more likely, in the opinion of S&P, to lead to a
weakened capacity to pay interest and repay principal for debt in this category
than in higher rated categories. According to published guidelines, securities
rated Baa by Moody's are considered by Moody's as medium grade obligations. Such
securities are, in the opinion of Moody's, neither highly protected nor poorly
secured. Interest payments and principal security appear to Moody's to be
adequate for the present but certain protective elements may be lacking or may
be characteristically unreliable over any great length of time. In the opinion
of Moody's they lack outstanding investment characteristics and in fact have
speculative characteristics as well. For a description of S&P's and Moody's
ratings see the Statement of Additional Information. From time to time, the Fund
also may invest up to 10% of its assets in tax exempt money market funds for
cash management purposes. Such instruments will be treated as investments in
municipal securities.
 
  The Fund may invest the remainder of its total assets in municipal securities
rated below investment grade at the time of investment and unrated municipal
securities that the Adviser considers to be of comparable quality to such
securities. According to published guidelines, securities rated below investment
grade are regarded by S&P, on balance, as predominantly speculative with respect
to capacity to pay interest and repay principal in accordance with the terms of
the obligation. While in the opinion of S&P such securities will likely have
some quality and protective characteristics, these are outweighed by large
uncertainties or major risk exposures to adverse conditions. According to
published guidelines, securities rated below investment grade are regarded by
Moody's as generally lacking characteristics of a desirable investment.
Assurance of interest and principal payments or of maintenance of other terms of
the securities' contract over any long period of time may, in the opinion of
Moody's, be small. Securities rated below investment grade commonly are referred
to as "junk bonds." For a description of S&P's and Moody's ratings see the
Statement of Additional Information.
 
  The foregoing policies with respect to credit quality of portfolio investments
will apply only at the time of purchase of a security, and the Fund will not be
required to dispose of a security in the event that S&P or Moody's (or any other
NRSRO) downgrades its assessment of the credit characteristics of a particular
issuer. In determining whether the Fund will retain or sell such a security, the
Adviser may consider such factors as the Adviser's assessment of the credit
quality of the issuer of such security, the price at which such security could
be sold and the rating, if any, assigned to such security by other NRSRO.
 
  Under current market conditions, the Fund anticipates that it will limit the
dollar-weighted average life of its portfolio to between three and ten years.
Generally, a portfolio of municipal securities having intermediate
dollar-weighted average life tends to produce a higher level of income than a
portfolio of municipal
 
                                       12
<PAGE>   207
 
securities having a shorter dollar-weighted average life and has less net asset
value volatility than a portfolio of municipal securities having a longer
dollar-weighted average life, although such differences cannot be assured. In
addition, market prices of municipal securities with intermediate maturities
generally fluctuate more in response to changes in interest rates than do market
prices of municipal securities with shorter maturities but generally fluctuate
less than market prices of municipal securities with longer maturities. Based on
the foregoing, the Adviser believes that under current market conditions the
yield and price characteristics of a municipal securities portfolio with a
dollar-weighted average life of three to ten years generally offer an attractive
balance between income and interest rate risk. In certain market conditions,
however, such a portfolio may be less attractive because of differences in yield
between municipal securities of different maturities due to supply and demand
forces, monetary and tax policies and investor expectations. In the event of
sustained market conditions that make it less desirable to maintain a dollar-
weighted average portfolio life of three to ten years, the Board of Trustees of
the Trust, after consultation with the Adviser, may change the investment policy
of the Fund with respect to the dollar-weighted average life of the portfolio.
The Fund's investment policy with respect to the dollar-weighted average life of
its portfolio is not a fundamental policy, and may be changed by the Trustees
without obtaining shareholder approval. There is no limitation with respect to
the expected life or stated maturity of individual municipal securities in the
Fund's portfolio.
 
  An investment in the Fund may not be appropriate for all investors. The Fund
is not intended to be a complete investment program, and investors should
consider their long-term investment goals and financial needs when making an
investment decision with respect to the Fund. An investment in the Fund is
intended to be a long-term investment and should not be used as a trading
vehicle.
 
- ------------------------------------------------------------------------------
MUNICIPAL SECURITIES
- ------------------------------------------------------------------------------
 
  GENERAL. Municipal securities are debt obligations issued by or on behalf of
the governments of states, territories or possessions of the United States, the
District of Columbia and their political subdivisions, agencies and
instrumentalities, certain interstate agencies and certain territories of the
United States, the interest on which, in the opinion of bond counsel or other
counsel to the issuer of such securities, is exempt from federal income tax.
Under normal market conditions, up to 100% but not less than 80%, of the Fund's
net assets will be invested in municipal securities. The foregoing is a
fundamental policy of the Fund and cannot be changed without approval of the
shareholders of the Fund.
 
  The two principal classifications of municipal securities are "general
obligation" and "revenue" securities. "General obligation" securities are
secured by the issuer's pledge of its faith, credit and taxing power for the
payment of principal and interest. "Revenue" securities are usually payable only
from the revenues derived from a particular facility or class of facilities or,
in some cases, from the proceeds of a
 
                                       13
<PAGE>   208
 
special excise tax or other specific revenue source. Industrial development
bonds are usually revenue securities, the credit quality of which is normally
directly related to the credit standing of the industrial user involved.
 
  Within these principal classifications of municipal securities, there are a
variety of types of municipal securities, including fixed and variable rate
securities, municipal notes, municipal leases, custodial receipts, participation
certificates and derivative municipal securities the terms of which include
elements of, or are similar in effect to, certain Strategic Transactions (as
defined below) in which the Fund may engage. Variable rate securities bear rates
of interest that are adjusted periodically according to formulae intended to
reflect market rates of interest and include securities whose rates vary
inversely with changes in market rates of interest. The Fund will not invest
more than 15% of its total assets in derivative municipal securities such as
inverse floaters, whose rates vary inversely with changes in market rates of
interest, or range floaters or capped floaters, whose rates are subject to
periodic or lifetime caps. Such securities may also pay a rate of interest
determined by applying a multiple to the variable rate. The extent of increases
and decreases in the value of securities whose rates vary inversely with market
rates of interest generally will be larger than comparable changes in the value
of an equal principal amount of a fixed rate municipal security having similar
credit quality, redemption provisions and maturity. Municipal notes include tax,
revenue and bond anticipation notes of short maturity, generally less than three
years, which are issued to obtain temporary funds for various public purposes.
Municipal leases are obligations issued by state and local governments or
authorities to finance the acquisition of equipment and facilities. Certain
municipal lease obligations may include "non-appropriation" clauses which
provide that the municipality has no obligation to make lease or installment
purchase payments in future years unless money is appropriated for such purpose
on a yearly basis. Custodial receipts are underwritten by securities dealers or
banks and evidence ownership of future interest payments, principal payments or
both on certain municipal securities. Participation certificates are obligations
issued by state and local governments or authorities to finance the acquisition
of equipment and facilities. They may represent participations in a lease, an
installment purchase contract, or a conditional sales contract. Municipal
securities may not be backed by the faith, credit and taxing power of the
issuer. Certain of the municipal securities in which the Fund may invest
represent relatively recent innovations in the municipal securities markets, and
the markets for such securities may be less developed than the market for
conventional fixed rate municipal securities. A more detailed description of the
types of municipal securities in which the Fund may invest is included in the
Statement of Additional Information.
 
  The net asset value of the Fund will change with changes in the value of its
portfolio securities. Because the Fund will invest primarily in fixed-income
municipal securities, the net asset value of the Fund can be expected to change
as general levels of interest rates fluctuate. When interest rates decline, the
value of a portfolio invested in fixed-income securities generally can be
expected to rise. Conversely,
 
                                       14
<PAGE>   209
 
when interest rates rise, the value of a portfolio invested in fixed-income
securities generally can be expected to decline. Volatility may be greater
during periods of general economic uncertainty.
 
  The Fund will invest at least 65% of its total assets in municipal securities
rated investment grade at the time of investment; however, such municipal
securities, like other debt obligations, are subject to the risk of non-payment.
The ability of issuers of municipal securities to make timely payments of
interest and principal may be adversely impacted in general economic downturns
and as relative governmental cost burdens are allocated and reallocated among
federal, state and local governmental units. Such non-payment would result in a
reduction of income to the Fund, and could result in a reduction in the value of
the municipal security experiencing non-payment and a potential decrease in the
net asset value of the Fund.
 
  The Fund may invest the remainder of its total assets in municipal securities
rated at the time of investment below investment grade or in unrated municipal
securities considered by the Adviser to be of comparable quality to such
securities. Securities rated below investment grade commonly are referred to as
"junk bonds". Higher yields generally are available from such municipal
securities. Investment in such lower grade municipal securities involves special
risks as compared with investment in investment grade municipal securities. The
market for lower grade municipal securities is considered to be less liquid than
the market for investment grade municipal securities, which may adversely affect
the ability of the Fund to dispose of such securities in a timely manner at a
price which, in the Adviser's judgment, reflects the value of such security. The
market price for less liquid securities tends to be more volatile than the
market price for more liquid securities. Illiquid securities and the absence of
readily available market quotations with respect thereto may make the Adviser's
valuation of such securities more difficult, and the Adviser's judgment may play
a greater role in the valuation of the Fund's securities. Lower grade municipal
securities generally involve greater credit risk than investment grade municipal
securities and are more sensitive to adverse economic changes, significant
increases in interest rates and individual issuer developments. Because issuers
of lower grade municipal securities frequently choose not to seek a rating of
their municipal securities, the Fund will rely more heavily on the Adviser's
ability to determine the relative investment quality of such securities than if
the Fund invested exclusively in investment grade municipal securities. More
detailed information concerning the risks associated with instruments in lower
grade municipal securities is included in the Fund's Statement of Additional
Information.
 
  The Adviser seeks to minimize the risks involved in investing in lower grade
municipal securities through diversification and careful investment analysis. To
the extent that there is no established retail market for some of the lower
grade municipal securities in which the Fund may invest, trading in such
securities may be relatively inactive. The Adviser is responsible for
determining the net asset value of the Fund, subject to the supervision of the
Board of Trustees of the Trust. During
 
                                       15
<PAGE>   210
 
periods of reduced market liquidity and in the absence of readily available
market quotations for lower grade municipal securities held in the Fund's
portfolio, the ability of the Adviser to value the Fund's securities becomes
more difficult and the Adviser's use of judgment may play a greater role in the
valuation of the Fund's securities due to the reduced availability of reliable
objective data. The effects of adverse publicity and investor perceptions may be
more pronounced for securities for which no established retail market exists as
compared with the effects on securities for which such a market does exist.
Further, the Fund may have more difficulty selling such securities in a timely
manner and at their stated value than would be the case for securities for which
an established retail market does exist.
 
   
  The table below sets forth the percentages of the Fund's assets invested as of
December 31, 1996 in the various S&P and Moody's rating categories and in
unrated securities determined by the Adviser to be of comparable quality. The
percentages are based on the dollar-weighted average of credit ratings of all
debt securities held by the Fund during the 1996 fiscal year computed on a
monthly basis.

</TABLE>
    
 
  The portfolio composition shown in the table above reflects the allocation of
assets by the Fund during a period in which the Fund did not acquire debt
securities rated below BBB by S&P and Baa by Moody's. The Fund currently may
acquire such debt securities. Accordingly, the percentage of the Fund's assets
invested in securities of various grades may from time to time vary
substantially from those set forth in the above table.
 
  The Fund has not established any limit on the percentage of its portfolio that
may be invested in municipal securities subject to the alternative minimum tax
provisions of federal tax law, and a substantial portion of the income produced
by the Fund may be taxable under the alternative minimum tax. The Fund may not
be a suitable investment for investors who are already subject to the federal
alternative minimum tax or who would become subject to the federal alternative
minimum tax
 
                                       16
<PAGE>   211
 
as a result of an investment in the Fund. In addition, income earned or deemed
to be earned with respect to the Fund's Strategic Transactions, if any, will be
taxable. See "Tax Status."
 
  From time to time, proposals have been introduced before Congress that would
have the effect of reducing or eliminating the federal tax exemption on
municipal securities. If such a proposal were enacted, the ability of the Fund
to pay tax exempt interest dividends might be adversely affected.
 
  SELECTION OF INVESTMENTS. The Adviser will buy and sell securities for the
Fund's portfolio with a view to seeking a high level of current income exempt
from federal income tax and will select securities which the Adviser believes
entail reasonable credit risk considered in relation to the investment policies
of the Fund. As a result, the Fund will not necessarily invest in the highest
yielding tax-exempt municipal securities permitted by the investment policies if
the Adviser determines that market risks or credit risks associated with such
investments would subject the Fund's portfolio to excessive risk. The potential
for realization of capital gains resulting from possible changes in interest
rates will not be a major consideration. Other than for tax purposes, frequency
of portfolio turnover generally will not be a limiting factor if the Fund
considers it advantageous to purchase or sell securities. The Fund may have
annual portfolio turnover rates in excess of 100%. A high rate of portfolio
turnover involves correspondingly greater brokerage commission expenses or
dealer costs than a lower rate, which expenses and costs must be borne by the
Fund and its shareholders. High portfolio turnover may also result in the
realization of substantial net short-term capital gains and any distributions
resulting from such gains will be taxable. See "Tax Status" in this Prospectus
and "Investment Policies and Restrictions" in the Statement of Additional
Information.
 
  TEMPORARY DEFENSIVE STRATEGIES. At times conditions in the markets for tax-
exempt municipal securities may, in the Adviser's judgment, make pursuing the
Fund's basic investment strategy inconsistent with the best interests of its
shareholders. At such times, the Adviser may use alternative strategies
primarily designed to reduce fluctuations in the value of the Fund's assets. In
implementing these "defensive" strategies, the Fund may invest to a substantial
degree in high-quality, short-term municipal obligations. If these high-quality,
short-term municipal obligations are not available or, in the Adviser's
judgment, do not afford sufficient protection against adverse market conditions,
the Fund may invest in taxable obligations. Such taxable obligations may
include: obligations of the U.S. Government, its agencies or instrumentalities;
other debt securities rated within the four highest grades by either S&P or
Moody's (or comparably rated by any other NRSRO); commercial paper rated in the
highest grade by either rating service (or comparably rated by any other NRSRO);
certificates of deposit and bankers' acceptances; repurchase agreements with
respect to any of the foregoing investments; or any other fixed-income
securities that the Adviser considers consistent with such strategy. To the
extent that the Fund invests a substantial portion of its assets in taxable
securities for temporary defensive purposes, the Fund will not be
 
                                       17
<PAGE>   212
 
invested in a manner primarily designed to achieve a high level of current
income exempt from federal income tax.
 
- ------------------------------------------------------------------------------
INVESTMENT PRACTICES
- ------------------------------------------------------------------------------
 
  In connection with the investment policies described above, the Fund also may
engage in strategic transactions and purchase and sell securities on a "when
issued" and "delayed delivery" basis. These investments entail risks. Strategic
transactions generally will not be treated as investments in tax-exempt
municipal securities for purposes of the Fund's 80% investment policy with
respect thereto.
 
  STRATEGIC TRANSACTIONS. The Fund may purchase and sell derivative instruments
such as exchange-listed and over-the-counter put and call options on securities,
financial futures, fixed-income indices and other financial instruments,
purchase and sell financial futures contracts and enter into various interest
rate transactions such as swaps, caps, floors or collars. Collectively, all of
the above are referred to as "Strategic Transactions." Strategic Transactions
may be used to attempt to protect against possible changes in the market value
of securities held in or to be purchased for the Fund's portfolio resulting from
securities markets, to protect the Fund's unrealized gains in the value of its
portfolio securities, to facilitate the sale of such securities for investment
purposes, to manage the effective maturity or duration of the Fund's portfolio,
or to establish a position in the derivatives markets as a temporary substitute
for purchasing or selling particular securities. Any or all of these investment
techniques may be used at any time and there is no particular strategy that
dictates the use of one technique rather than another, as use of any Strategic
Transaction is a function of numerous variables including market conditions. The
ability of the Fund to utilize these Strategic Transactions successfully will
depend on the Adviser's ability to predict pertinent market movements, which
cannot be assured. The Fund will comply with applicable regulatory requirements
when implementing these strategies, techniques and instruments.
 
  Strategic Transactions have risks associated with them including possible
default by the other party to the transaction, illiquidity and, to the extent
the Adviser's view as to certain market movements is incorrect, the risk that
the use of such Strategic Transactions could result in losses greater than if
they had not been used. Use of put and call options may result in losses to the
Fund, force the sale of portfolio securities at inopportune times or for prices
other than at current market values, limit the amount of appreciation the Fund
can realize on its investments or cause the Fund to hold a security it might
otherwise sell. The use of options and futures transactions entails certain
other risks. In particular, the variable degree of correlation between price
movements of futures contracts and price movements in the related portfolio
position of the Fund creates the possibility that losses on the hedging
instrument may be greater than gains in the value of the Fund's position. In
addition, futures and options markets may not be liquid in all circumstances and
certain over-the-counter options may have no markets. As a result, in certain
 
                                       18
<PAGE>   213
 
markets, the Fund might not be able to close out a transaction without incurring
substantial losses, if at all. Although the contemplated use of these futures
contracts and options thereon should tend to minimize the risk of loss due to a
decline in the value of the hedged position, at the same time they tend to limit
any potential gain which might result from an increase in value of such
position. Finally, the daily variation margin requirements for futures contracts
would create a greater ongoing potential financial risk than would purchases of
options, where the exposure is limited to the cost of the initial premium.
Losses resulting from the use of Strategic Transactions would reduce net asset
value, and possibly income, and such losses can be greater than if the Strategic
Transactions had not been utilized. The Strategic Transactions that the Fund may
use and some of their risks are described more fully in the Fund's Statement of
Additional Information.
 
  Income earned or deemed to be earned, if any, by the Fund from its Strategic
Transactions will generally be taxable income of the Fund. See "Tax Status."
 
   
  "WHEN ISSUED" AND "DELAYED DELIVERY" TRANSACTIONS.  The Fund may also purchase
and sell municipal securities on a "when issued" and "delayed delivery" basis.
No income accrues to the Fund on municipal securities in connection with such
purchase transactions prior to the date the Fund actually takes delivery of such
securities. These transactions are subject to market fluctuation; the value of
the municipal securities at delivery may be more or less than their purchase
price, and yields generally available on municipal securities when delivery
occurs may be higher or lower than yields on the municipal securities obtained
pursuant to such transactions. Because the Fund relies on the buyer or seller,
as the case may be, to consummate the transaction, failure by the other party to
complete the transaction may result in the Fund missing the opportunity of
obtaining a price or yield considered to be advantageous. When the Fund is the
buyer in such a transaction, however, it will maintain, in a segregated account
with its custodian, cash or liquid securities having an aggregate value equal to
the amount of such purchase commitments until payment is made. The Fund will
make commitments to purchase municipal securities on such basis only with the
intention of actually acquiring these securities, but the Fund may sell such
securities prior to the settlement date if such sale is considered to be
advisable. To the extent the Fund engages in "when issued" and "delayed
delivery" transactions, it will do so for the purpose of acquiring securities
for the Fund's portfolio consistent with the Fund's investment objectives and
policies and not for the purposes of investment leverage. No specific limitation
exists as to the percentage of the Fund's assets which may be used to acquire
securities on a "when issued" or "delayed delivery" basis.
    
 
  RESTRICTED AND ILLIQUID SECURITIES.  The Fund may invest up to 15% of its net
assets in illiquid securities including securities the disposition of which is
subject to substantial legal or contractual restrictions on resale and
securities that are not readily marketable. The sale of restricted and illiquid
securities often requires more time and results in higher brokerage charges or
dealer discounts and other selling
 
                                       19
<PAGE>   214
 
expenses than does the sale of securities eligible for trading on national
securities exchanges or in the over-the-counter markets. Restricted securities
may sell at a price lower than similar securities that are not subject to
restrictions on resale. Restricted securities salable among qualified
institutional buyers without restriction pursuant to Rule 144A under the
Securities Act of 1933 that are determined to be liquid by the Adviser under
guidelines adopted by the Board of Trustees of the Trust (under which guidelines
the Adviser will consider factors such as trading activities and the
availability of price quotations), will not be treated as restricted securities
by the Fund pursuant to such rules.
 
  OTHER PRACTICES.  The Fund may borrow amounts up to 5% of its net assets in
order to pay for redemptions when liquidation of portfolio securities is
considered disadvantageous or inconvenient and may pledge up to 10% of its net
assets to secure such borrowings.
 
  The Fund generally will not invest more than 25% of its total assets in any
industry, nor will the Fund generally invest more than 5% of its assets in the
securities of any single issuer. Governmental issuers of municipal securities
are not considered part of any "industry." However, municipal securities backed
only by the assets and revenues of nongovernmental users may for this purpose be
deemed to be issued by such nongovernmental users, and the 25% limitation would
apply to such obligations. It is nonetheless possible that the Fund may invest
more than 25% of its assets in a broader segment of the municipal securities
market, such as revenue obligations of hospitals and other health care
facilities, housing agency revenue obligations, or airport revenue obligations
if the Adviser determines that the yields available from obligations in a
particular segment of the market justified the additional risks associated with
a large investment in such segment. Although such obligations could be supported
by the credit of governmental users, or by the credit of nongovernmental users
engaged in a number of industries, economic, business, political and other
developments generally affecting the revenues of such users (for example,
proposed legislation or pending court decisions affecting the financing of such
projects and market factors affecting the demand for their services or products)
may have a general adverse effect on all municipal securities in such a market
segment. The Fund reserves the right to invest more than 25% of its assets in
industrial development bonds or in issuers located in the same state, although
it has no present intention to invest more than 25% of its assets in issuers
located in the same state. If the Fund were to invest more than 25% of its
assets in issuers located in the same state, it would be more susceptible to
adverse economic, business, or regulatory conditions in that state.
 
  The Fund may invest a substantial portion of its assets in municipal
securities that pay interest that is subject to the federal alternative minimum
tax. The Fund may not be a suitable investment for investors who are already
subject to the federal alternative minimum tax or who would become subject to
the federal alternative minimum tax as a result of an investment in the Fund.

  INVESTMENT RESTRICTIONS.  The Fund is subject to certain investment
restrictions which constitute fundamental policies. Fundamental policies cannot
be changed without the approval of the holders of a majority of the Fund's
outstanding voting securities, as defined in the Investment Company Act of 1940,
as amended (the "1940 Act"). See "Investment Policies and Restrictions" in the
Statement of Additional Information.
 
  PORTFOLIO TRANSACTIONS AND BROKERAGE ALLOCATION.  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 prices and any
brokerage commissions. The securities in which the Fund invests are traded
principally in the over-the-counter market. In the over-the-counter market,
securities generally are 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 mark-up to the dealer. Securities purchased in
underwritten offerings generally include, in the price, a fixed amount of
compensation for the managers, underwriters and dealers. The Fund may also
purchase certain money market instruments directly from an issuer, in which case
no commissions or discounts are paid. Purchases and sales of bonds on a stock
exchange are effected through brokers who charge a commission for their
services.
 
  The Adviser is responsible for effecting securities transactions of the Fund
and will do so in a manner deemed fair and reasonable to shareholders of the
Fund and not according to any formula. The Adviser's primary considerations in
selecting the manner of executing securities transactions for the Fund will be
prompt execution of orders, the size and breadth of the market for the security,
the reliability, integrity and financial condition and execution capability of
the firm, the size of and difficulty in executing the order, and the best net
price. There are many instances when, in the judgment of the Adviser, more than
one firm can offer comparable execution services. In selecting among such firms,
consideration is given to those firms which supply research and other services
in addition to execution services. However, it is not the policy of the Adviser,
absent special circumstances, to pay higher commissions to a firm because it has
supplied such services.
 
  In effecting purchases and sales of the Fund's portfolio securities, the
Adviser and the Fund may place orders with and pay brokerage commissions to
brokers, including brokers which may be affiliated with the Fund, the Adviser
and the Distributor or dealers participating in the offering of the Fund's
shares. In addition, in selecting among firms to handle a particular
transaction, the Adviser and the Fund may take into account whether the firm has
sold or is selling shares of the Fund. See "Portfolio Transactions and Brokerage
Allocation" in the Statement of Additional Information for more information.

- ------------------------------------------------------------------------------
ALTERNATIVE SALES ARRANGEMENTS
- ------------------------------------------------------------------------------
 
  The Alternative Sales Arrangements permit an investor to choose the method of
purchasing shares that is more beneficial to the investor, taking into account
the amount of the purchase, the length of time the investor expects to hold the
shares, whether the investor wishes to receive dividends in cash or to reinvest
them in additional shares of the Fund, and other circumstances. Investors should
consider such factors together with the amount of sales charges and accumulated
distribution and service fees with respect to each class of shares that may be
incurred over the anticipated duration of their investment in the Fund.
 
                                       23
<PAGE>   218
 
  The Fund offers three classes of shares, designated Class A Shares, Class B
Shares and Class C Shares. Shares of each class are offered at a price equal to
their net asset value per share plus a sales charge which, at the election of
the purchaser, may be imposed (a) at the time of purchase ("Class A Shares") or
(b) on a contingent deferred basis (Class A Share accounts over $1 million,
"Class B Shares" and "Class C Shares"). Class A Share accounts over $1 million
or otherwise subject to a contingent deferred sales charge ("CDSC"), Class B
Shares and Class C Shares sometimes are referred to herein collectively as
"Contingent Deferred Sales Charge Shares" or "CDSC Shares."
 
  The minimum initial investment with respect to each class of shares is $500.
The minimum subsequent investment with respect to each class of shares is $25.
It is presently the policy of the Distributor, not to accept any order for Class
B Shares in an amount of $500,000 or more and not to accept any order for Class
C Shares in an amount of $1 million or more because it ordinarily will be more
advantageous for an investor making such an investment to purchase Class A
Shares.
 
  An investor should carefully consider the sales charges applicable to each
class of shares and the estimated period of their investment to determine which
class of shares is more beneficial for the investor to purchase. For example,
investors who would qualify for a significant purchase price discount from the
maximum sales charge on Class A Shares may determine that payment of such a
reduced front-end sales charge is superior to electing to purchase Class B
Shares or Class C Shares, each with no front-end sales charge but subject to a
CDSC and a higher aggregate distribution and service fee. However, because
initial sales charges are deducted at the time of purchase of Class A Share
accounts under $1 million, a purchaser of such Class A Shares would not have all
of his or her funds invested initially and therefore, would initially own fewer
shares than if Class B Shares or Class C Shares had been purchased. On the other
hand, an investor whose purchase would not qualify for price discounts
applicable to Class A Shares and intends to remain invested until after the
expiration of the applicable CDSC may wish to defer the sales charge and have
all his or her funds initially invested in Class B Shares or Class C Shares. If
such an investor anticipates that he or she will redeem such shares prior to the
expiration of the CDSC period applicable to Class B Shares, the investor may
wish to acquire Class C Shares. Investors must weigh the benefit of deferring
the sales charge and having all of their funds invested against the higher
aggregate distribution and service fee applicable to Class B Shares and Class C
Shares (discussed below).
 
  Each class of shares represents an interest in the same portfolio of
investments of the Fund and has the same rights, except each class of shares (i)
bears those distribution fees, service fees and administrative expenses
applicable to the respective class of shares as a result of its sales
arrangements, (ii) has exclusive voting rights with respect to those provisions
of the Fund's Rule 12b-1 distribution plan which relate only to such class and
(iii) has a different exchange privilege. Generally, a class of shares subject
to a higher ongoing distribution and service fee
 
                                       24
<PAGE>   219
 
or subject to the conversion feature will have a higher expense ratio and pay
lower dividends than a class of shares subject to a lower ongoing distribution
and service fee or not subject to the conversion feature. The per share net
asset values of the different classes of shares are expected to be substantially
the same; from time to time, however, the per share net asset values of the
classes may differ. The net asset value per share of each class of shares of the
Fund will be determined as described in this Prospectus under "Purchase of
Shares -- Net Asset Value."
 
   
  The administrative expenses that may be allocated to a specific class of
shares may consist of (i) ACCESS' expenses attributable to a specific class of
shares, which expenses typically will be higher with respect to classes of
shares subject to the conversion feature; (ii) printing and postage expenses
related to preparing and distributing materials such as shareholder reports,
prospectuses and proxy statements to current shareholders of a specific class;
(iii) Securities and Exchange Commission (the "SEC") registration fees incurred
by a class of shares; (iv) the expense of administrative personnel and services
as required to support the shareholders of a specific class; (v) Trustees' fees
or expense incurred as a result of issues relating to one class of shares; (vi)
accounting expenses relating solely to one class of shares; and (vii) any other
incremental expenses subsequently identified that should be properly allocated
to one or more classes of shares. All such expenses incurred by a class will be
borne on a pro rata basis by the outstanding shares of such class. All
allocations of administrative expenses to a particular class of shares will be
limited to the extent necessary to preserve the Fund's qualification as a
regulated investment company under the Internal Revenue Code of 1986, as amended
(the "Code").
    
 
- ------------------------------------------------------------------------------
PURCHASE OF SHARES
- ------------------------------------------------------------------------------
 
   
  The Fund offers three classes of shares to the public on a continuous basis
through the Distributor, as principal underwriter, which is located at One
Parkview Plaza, Oakbrook Terrace, Illinois 60181. Shares also are offered
through members of the National Association of Securities Dealers, Inc. ("NASD")
acting as securities dealers ("dealers") and through NASD members acting as
brokers for investors ("brokers") or eligible non-NASD members acting as agents
for investors ("financial intermediaries"). The Fund reserves the right to
suspend or terminate the continuous public offering of its shares at any time
and without prior notice.
    
 
  The Fund's shares are offered at the net asset value per share next computed
after an investor places an order to purchase directly with the investor's
broker, dealer or financial intermediary or with the Distributor plus any
applicable sales charge. Sales personnel of brokers, dealers and financial
intermediaries distributing the Fund's shares may receive differing compensation
for selling different classes of shares. It is the responsibility of the
investor's broker, dealer or financial intermediary to transmit the order to the
Distributor. Because the Fund generally will determine net asset value once each
business day as of the close of business, purchase orders
 
                                       25
<PAGE>   220
 
placed through an investor's broker, dealer or financial intermediary must be
transmitted to the Distributor by such broker, dealer or financial intermediary
prior to such time in order for the investor's order to be fulfilled on the
basis of the net asset value to be determined that day. Any change in the
purchase price due to the failure of the Distributor to receive a purchase order
prior to such time must be settled between the investor and the broker, dealer
or financial intermediary submitting the order.
 
   
  The Distributor may from time to time implement programs under which a broker,
dealer or financial intermediary's sales force may be eligible to win nominal
awards for certain sales efforts or under which the Distributor will reallow to
any broker, dealer or financial intermediary that sponsors sales contests or
recognition programs conforming to criteria established by the Distributor, or
participates in sales programs sponsored by the Distributor, an amount not
exceeding the total applicable sales charges on the sales generated by the
broker, dealer or financial intermediary at the public offering price during
such programs. Other programs provide, among other things, and subject to
certain conditions, for certain favorable distribution arrangements for shares
of the Fund. Also, the Distributor in its discretion may from time to time,
pursuant to objective criteria established by it, pay fees to, and sponsor
business seminars for, qualifying brokers, dealers or financial intermediary for
certain services or activities which are primarily intended to result in sales
of shares of the Fund. Fees may include payment for travel expenses, including
lodging, incurred in connection with trips taken by invited registered
representatives and members of their families to locations within or outside of
the United States for meetings or seminars of a business nature. In some
instances additional compensation or promotional incentives may be offered to
brokers, dealers or financial intermediaries that have sold or may sell
significant amounts of shares during specified periods of time. The Distributor
may provide additional compensation to Edward D. Jones & Co. or an affiliate
thereof based on a combination of its sales of shares and increases in assets
under management. Such payments to brokers, dealers and financial intermediaries
for sales contests, other sales programs and seminars are made by the
Distributor out of its own assets and not out of the assets of the Fund. Such
fees paid for such services and activities with respect to the Fund will not
exceed in the aggregate 1.25% of the average total daily net assets of the Fund
on an annual basis. These programs will not change the price an investor will
pay for shares or the amount that the Fund will receive from such sale.
    
 
CLASS A SHARES
 
  The public offering price of Class A Shares is equal to the net asset value
per share plus an initial sales charge which is a variable percentage of the
offering price depending upon the amount of the sale. The table below shows
total sales charges and dealer concessions reallowed to dealers and agency
commissions paid to brokers with respect to sales of Class A Shares. The sales
charge is allocated between the investor's broker, dealer or financial
intermediary and the Distributor. As indicated above, at the discretion of the
Distributor, the entire sales charge may be reallowed to such broker, dealer or
financial intermediary. The staff of the SEC has taken the
 
                                       26
<PAGE>   221
 
position that brokers, dealers or financial intermediaries who receive more than
90% of the sales charge may be deemed to be "underwriters" as that term is
defined in the Securities Act of 1933, as amended.

   * No sales charge is payable at the time of purchase on investments of $1
     million or more, although for such investments the Fund imposes a CDSC
     of 1.00% on redemptions made within one year of the purchase. A
     commission will be paid to brokers, dealers or financial intermediaries
     who initiate and are responsible for purchases of $1 million or more as
     follows: 1.00% on sales to $2 million, plus 0.80% on the next $1
     million and 0.50% on the excess over $3 million. See "Purchase of
     Shares -- Deferred Sales Charge Alternatives" for additional
     information with respect to CDSCs.
    
 
QUANTITY DISCOUNTS
 
  Investors purchasing Class A Shares may, under certain circumstances, be
entitled to pay reduced sales charges. The circumstances under which such
investors may pay reduced sales charges are described below.
 
  Investors, or their brokers, dealers or financial intermediaries, must notify
the Fund whenever a quantity discount is applicable to purchases. Upon such
notification, an investor will receive the lowest applicable sales charge.
Quantity discounts may be modified or terminated at any time. For more
information about quantity discounts, investors should contact their broker,
dealer or financial intermediary or the Distributor.
 
   
  A person eligible for a reduced sales charge includes an individual, their
spouse and children under 21 years of age and any corporation, partnership or
sole proprietorship which is 100% owned, either alone or in combination, by any
of the foregoing; a trustee or other fiduciary of a single trust estate or a
single fiduciary account; or a "company" as defined is section 2(a)(8) of the
1940 Act.
    
 
   
  As used herein, "Participating Funds" refers to certain open-end investment
companies advised by the Adviser or Van Kampen American Capital Asset
Management, Inc. and distributed by the Distributor. Additional Funds may be
    
 
                                       27
<PAGE>   222
 
   
added from time to time as determined by the Fund's Board of Trustees as
Participating Funds.
    
 
   
  VOLUME DISCOUNTS. The size of investment shown in the preceding sales charge
table applies to the total dollar amount being invested by any person at any one
time in Class A Shares of the Fund, or in any combination of shares of the Fund
and shares of other Participating Funds, although other Participating Funds may
have different sales charges.
    
 
   
  CUMULATIVE PURCHASE DISCOUNT. The size of investment shown in the preceding
sales charge table may also be determined by combining the amount being invested
in Class A Shares of the Fund with other shares of the Fund and shares of
Participating Funds, plus the current offering price of all shares of the Fund
and other Participating Funds which have been previously purchased and are still
owned.
    
 
   
  LETTER OF INTENT. A Letter of Intent provides an opportunity for an investor
to obtain a reduced sales charge by aggregating the amount being invested over a
13-month period to determine the sales charge as outlined in the preceding sales
charge table. The size of investment shown in the preceding table includes the
amount of intended purchases of Class A Shares of the Fund with other shares of
the Fund and shares of the Participating Funds plus the value of all shares of
the Fund and other Participating Funds previously purchased during such 13-month
period and still owned. An investor may elect to compute the 13-month period
starting up to 90 days before the date of execution of a Letter of Intent. Each
investment made during the period receives the reduced sales charge applicable
to the total amount of the investment goal. If trades not initially made under a
Letter of Intent subsequently qualify for a lower sales charge through the
90-day back-dating provision, an adjustment will be made at the expiration of
the Letter of Intent to give effect to the lower charge. If the goal is not
achieved within the 13-month period, the investor must pay the difference
between the sales charge applicable to the purchases made and the sales charges
previously paid. When an investor signs a Letter of Intent, shares equal to at
least 5% of the total purchase amount of the level selected will be restricted
from sale or redemption by the investor until the Letter of Intent is satisfied
or any additional sales charges have been paid; if the Letter of Intent is not
satisfied by the investor and any additional sales charges are not paid,
sufficient restricted shares will be redeemed by the Fund to pay such charges.
Additional information is contained in the application accompanying this
Prospectus.
    
 
OTHER PURCHASE PROGRAMS
 
   
  Purchasers of Class A Shares may be entitled to reduced initial sales charges
in connection with unit investment trust reinvestment programs and purchases by
registered representatives of selling firms or purchases by persons affiliated
with the Fund or the Distributor. The Fund reserves the right to modify or
terminate these arrangements at any time.
    
 
                                       28
<PAGE>   223
 
  UNIT INVESTMENT TRUST REINVESTMENT PROGRAMS. The Fund permits unitholders of
unit investment trusts to reinvest distributions from such trusts in Class A
Shares of the Fund at net asset value with no minimum initial or subsequent
investment requirement if the administrator of an investor's unit investment
trust program meets certain uniform criteria relating to cost savings by the
Fund and the Distributor. The total sales charge for all other investments made
from unit trust distributions will be 1.00% of the offering price (1.01% of net
asset value). Of this amount, the Distributor will pay to the broker, dealer or
financial intermediary, if any, through which such participation in the
qualifying program was initiated 0.50% of the offering price as a dealer
concession or agency commission. Persons desiring more information with respect
to this program, including the applicable terms and conditions thereof, should
contact their broker, dealer, financial intermediary or the Distributor.
 
   
  The administrator of such a unit investment trust must have an agreement with
the Distributor pursuant to which the administrator will (1) submit a single
bulk order and make payment with a single remittance for all investments in the
Fund during each distribution period by all investors who choose to invest in
the Fund through the program and (2) provide ACCESS with appropriate backup data
for each participating investor in a computerized format fully compatible with
ACCESS' processing system.
    
 
   
  As further requirements for obtaining these special benefits, the Fund also
requires that all dividends and other distributions by the Fund be reinvested in
additional shares without any systematic withdrawal program. There will be no
minimum for reinvestments from unit investment trusts. The Fund will send
account activity statements to such participants on a monthly basis only, even
if their investments are made more frequently. The Fund reserves the right to
modify or terminate this program at any time.
    
 
  NAV PURCHASE OPTIONS. Class A Shares of the Fund may be purchased at net asset
value, upon written assurance that the purchase is made for investment purposes
and that the shares will not be resold except through redemption by the Fund,
by:
 
   
  (1) Current or retired trustees or directors of funds advised by the Adviser
      or Van Kampen American Capital Asset Management, Inc. and such persons'
      families and their beneficial accounts.
    
 
   
  (2) Current or retired directors, officers and employees of Morgan Stanley
      Group Inc. and any of its subsidiaries, employees of an investment
      subadviser to any fund described in (1) above or an affiliate of such
      subadviser; and such persons' families and their beneficial accounts.
    
 
   
  (3) Directors, officers, employees and registered representatives of financial
      institutions that have a selling group agreement with the Distributor and
      their spouses and children under 21 years of age when purchasing for any
      accounts they beneficially own, or, in the case of any such financial

      institution, when purchasing for retirement plans for such institution's
      employees.
 
   
  (4) Registered investment advisers, trust companies and bank trust departments
      investing on their own behalf or on behalf of their clients provided that
      the aggregate amount invested in Class A Shares of the Fund alone, or any
      combination of shares of the Fund and shares of other Participating Funds
      as described herein under "Purchase of Shares -- Class A Shares --
      Quantity Discounts," during the 13-month period commencing with the first
      investment pursuant hereto equals at least $1 million. The Distributor may
      pay brokers, dealers or financial intermediaries through which purchases
      are made an amount up to 0.50% of the amount invested, over a 12-month
      period following such transaction.
    
 
   
  (5) Trustees and other fiduciaries purchasing shares for retirement plans of
      organizations with retirement plan assets of $3 million or more and which
      invest in multiple fund families through national wirehouse alliance
      programs.
    
 
  (6) Accounts as to which a broker, dealer or financial intermediary charges an
      account management fee ("wrap accounts"), provided the broker, dealer or
      financial intermediary has a separate agreement with the Distributor.
 
  (7) Investors purchasing shares of the Fund with redemption proceeds from
      other mutual fund complexes on which the investor has paid a front-end
      sales charge or was subject to a deferred sales charge, whether or not
      paid, if such redemption has occurred no more than 30 days prior to such
      purchase.
 
   
  (8) Trusts created under pension, profit sharing or other employee benefit
      plans qualified under Section 401(a) of the Code, or custodial accounts
      held by a bank created pursuant to Section 403(b) of the Code and
      sponsored by non-profit organizations defined under Section 501(c)(3) of
      the Code and assets held by an employer or trustee in connection with an
      eligible deferred compensation plan under Section 457 of the Code. Such
      plans will qualify for purchases at net asset value provided, for plans
      initially establishing accounts with the Distributor in the Participating
      Funds after February 1, 1997, that (1) the initial amount invested in the
      Participating Funds is at least $500,000 or (2) such shares are purchased
      by an employer sponsored plan with more than 100 eligible employees. Such
      plans that have been established with a Participating Fund or have
      received proposals from the Distributor prior to February 1, 1997 based on
      net asset value purchase privileges previously in effect will be qualified
      to purchase shares of the Participating Funds at net asset value for
      accounts established on or before May 1, 1997. Section 403(b) and similar
      accounts for which Van Kampen American Capital Trust Company served as
      custodian will not be eligible for net asset value purchases based on the
      aggregate investment made by the plan or the number of eligible employees,
      except under certain uniform
    
 
                                       30
<PAGE>   225
 
   
criteria established by the Distributor from time to time. Prior to February 1,
1997, a commission will be paid to authorized dealers who initiate and are
responsible for such purchases within a rolling twelve-month period as follows:
      1.00% on sales to $5 million, plus 0.50% on the next $5 million and 0.25%
      on the excess over $10 million. For purchases on February 1, 1997 and
      thereafter, a commission will be paid as follows: 1.00% on sales to $2
      million, plus 0.80% on the next $1 million, plus 0.50% on the next $47
      million and 0.25% on the excess over $50 million.
    
 
   
  (9) Individuals who are members of a "qualified group". For this purpose, a
      qualified group is one which (i) has been in existence for more than six
      months, (ii) has a purpose other than to acquire shares of the Fund or
      similar investments, (iii) has given and continues to give its endorsement
      or authorization, on behalf of the group, for purchase of shares of the
      Fund and other Participating Funds, (iv) has a membership that the
      authorized dealer can certify as to the group's members and (v) satisfies
      other uniform criteria established by the Distributor for the purpose of
      realizing economics of scale in distributing such shares. A qualified
      group does not include one whose sole organizational nexus, for example,
      is that its participants are credit card holders of the same institution,
      policy holders of an insurance company, customers of a bank or
      broker-dealer, clients of an investment adviser or other similar groups.
      Shares purchased in each group's participants account in connection with
      this privilege will be subject to a CDSC of 1.00% in the event of
      redemption within one year of purchase, and a commission will be paid to
      authorized dealers who initiate and are responsible for such sales to each
      individual as follows: 1.00% on sales to $2 million, plus 0.80% on the
      next $1 million and 0.50% on the excess over $3 million.
    
 
   
The term "families" includes a person's spouse, children under 21 years of age
and grandchildren, parents, and a person's spouse's parents.
    
 
   
  Purchase orders made pursuant to clause (4) may be placed either through
authorized brokers, dealers or financial intermediaries as described above or
directly with ACCESS, the investment adviser, trust company or bank trust
department, provided that ACCESS receives federal funds for the purchase by the
close of business on the next business day following acceptance of the order. An
authorized broker, dealer or financial intermediary may charge a transaction fee
for placing an order to purchase shares pursuant to this provision or for
placing a redemption order with respect to such shares. The Fund may terminate,
or amend the terms of, offering shares of the Fund at net asset value to such
groups at any time.
    
 
DEFERRED SALES CHARGE ALTERNATIVES
 
  Investors choosing the deferred sales charge alternative may purchase Class A
Shares in an amount of $1 million or more, Class B Shares or Class C Shares. The
public offering price of a CDSC Share is equal to the net asset value per share
without the imposition of a sales charge at the time of purchase. CDSC Shares
are
 
                                       31
<PAGE>   226
 
   
sold without an initial sales charge so that the Fund will receive the full
amount of the investor's purchase payment. The Distributor will compensate
brokers, dealers and financial intermediaries participating in the continuous
public offering of the CDSC Shares out of its own assets, and not out of the
assets of the Fund, at a percentage rate of the dollar value of the CDSC Shares
purchased from the Fund by such brokers, dealers and financial intermediaries,
which percentage rate will be equal to (i) with respect to Class A Shares, 1.00%
on sales to $2 million, plus 0.80% on the next $1 million and 0.50% on the
excess over $3 million; (ii) 3.00% with respect to Class B Shares; and (iii)
1.00% with respect to Class C Shares. Such compensation will not change the
price an investor will pay for CDSC Shares or the amount that the Fund will
receive from such sale.
    
 
   
  CDSC Shares redeemed within a specified period of time generally will be
subject to a CDSC at the rates set forth below charged as a percentage of the
dollar amount subject thereto. The amount of the CDSC will vary depending on (i)
the class of CDSC Shares to which such shares belong and (ii) the number of
years from the time of payment for the purchase of the CDSC Shares until the
time of their redemption. The charge will be assessed on an amount equal to the
lesser of the then current market value or the original purchase price of the
CDSC Shares being redeemed. Accordingly, no contingent deferred sales charge
will be imposed on increases in net asset value above the initial purchase
price. In addition, no CDSC will be assessed on CDSC Shares derived from
reinvestment of dividends or capital gains distributions. Solely for purposes of
determining the number of years from the time of any payment for the purchase of
CDSC Shares, all payments during a month will be aggregated and deemed to have
been made on the last day of the month.
    
 
   
  Proceeds from the CDSC and the distribution fee applicable to a class of CDSC
Shares are paid to the Distributor and are used by the Distributor to defray its
expenses related to providing distribution related services to the Fund in
connection with the sale of shares of such class of CDSC Shares, such as the
payment of compensation to selected dealers and agents for selling such shares.
The combination of the CDSC and the distribution fees facilitates the ability of
the Fund to sell such CDSC Shares without a sales charge being deducted at the
time of purchase.
    
 
   
  In determining whether a CDSC is applicable to a redemption of CDSC Shares, it
will be assumed that the redemption is made first of any CDSC Shares acquired
pursuant to reinvestment of dividends or distributions, second of CDSC Shares
that have been held for a sufficient period of time such that the CDSC no longer
is applicable to such shares, third of Class A Shares in the shareholder's Fund
account that have converted from Class B Shares or Class C Shares, if any, and
fourth of CDSC Shares held longest during the period of time that a CDSC is
applicable to such CDSC Shares. The charge will not be applied to dollar amounts
representing an increase in the net asset value per share since the time of
purchase.
    
 
  To provide an example, assume an investor purchased 100 Class B Shares at $10
per share (at a cost of $1,000) and in the second year after purchase, the net
 
                                       32
<PAGE>   227
 
asset value per share is $12 and, during such time, the investor has acquired 10
additional Class B Shares upon dividend reinvestment. If at such time the
investor makes his first redemption of 50 shares (proceeds of $600), 10 shares
will not be subject to charge because of dividend reinvestment. With respect to
the remaining 40 shares, the charge is applied only to the original cost of $10
per share and not to the increase in net asset value of $2 per share. Therefore,
$400 of the $600 redemption proceeds will be charged at a rate of 2.5% (the
applicable rate in the second year after purchase).
 
   
  CLASS A SHARE PURCHASES OF $1 MILLION OR MORE. No sales charge is payable at
the time of purchase on investments in Class A Shares of $1 million or more,
although for such investments the Fund imposes a CDSC of 1.00% on redemptions
made within one year of the purchase. A commission will be paid to dealers who
initiate and are responsible for purchases of $1 million or more as follows:
1.00% on sales to $2 million, plus 0.80% on the next $1 million and 0.50% on the
excess over $3 million.
    
 
   
  CLASS B SHARES.  Class B Shares redeemed within four years of purchase
generally will be subject to a CDSC at the rates set forth below, charged as a
percentage of the dollar amount subject thereto:

  The CDSC generally is waived on redemptions of Class B Shares made pursuant to
the Systematic Withdrawal Plan. See "Shareholder Services -- Systematic
Withdrawal Plan."
    
 
   
  CLASS C SHARES. Class C Shares redeemed within the first 12 months of purchase
generally will be subject to a CDSC of 1.00% of the dollar amount subject
thereto. Class C Shares redeemed thereafter will not be subject to a CDSC.
    
 
   
  CONVERSION FEATURE. Class B Shares purchased on or after June 1, 1996 and any
dividend reinvestment plan shares received thereon, automatically convert to
Class A Shares eight years after the end of the calendar month in which the
shares were purchased. Class B Shares purchased before June 1, 1996, and any
dividend reinvestment plan shares received thereon, automatically convert to
Class A Shares six years after the end of the calendar month in which the shares
were purchased. Class C Shares purchased before January 1, 1997, and any
dividend reinvestment plan shares received thereon, automatically convert to
Class A Shares ten years
    
 
                                       33
<PAGE>   228
 
   
after the end of the calendar month in which such shares were purchased. Such
conversion will be on the basis of the relative net asset values per share,
without the imposition of any sales load, fee or other charge.
    
 
   
  The conversion of such shares to Class A Shares is subject to the continuing
availability of an opinion of counsel to the effect that (i) the assessment of
the higher distribution and service fees and ACCESS costs with respect to such
shares does not result in the Fund's dividends or distributions constituting
"preferential dividends" under the Internal Revenue Code of 1986, as amended
(the "Code"), and (ii) the conversion of such shares does not constitute a
taxable event under federal income tax law. The conversion may be suspended if
such an opinion is no longer available and such shares might continue to be
subject to the higher aggregate fees applicable to such class of shares for an
indefinite period.
    
 
   
  WAIVER OF CONTINGENT DEFERRED SALES CHARGE.  The CDSC is waived on redemptions
of Class B Shares and Class C Shares (i) following the death or disability (as
defined in the Code) of a shareholder, (ii) in connection with required minimum
distributions from an IRA or other retirement plan, (iii) pursuant to the Fund's
systematic withdrawal plan but limited to 12% annually of the initial value of
the account and (iv) effected pursuant to the right of the Fund to liquidate a
shareholder's account as described herein under "Redemption of Shares." The CDSC
also is waived on redemptions of Class C Shares as it relates to the
reinvestment of redemption proceeds in shares of the same class of the Fund
within 120 days after redemption. See "Shareholder Services" and "Redemption of
Shares" for further discussion of the waiver provisions.
    
 
NET ASSET VALUE
 
  The net asset value per share of the Fund will be determined separately for
each class of shares. The net asset value per share of a given class of shares
of the Fund is determined by calculating the total value of the Fund's assets
attributable to such class of shares, deducting its total liabilities
attributable to such class of shares, and dividing the result by the number of
shares of such class outstanding. The net asset value for the Fund is computed
once daily as of 5:00 p.m. Eastern time Monday through Friday, except on
customary business holidays, or except on any day on which no purchase or
redemption orders are received, or there is not a sufficient degree of trading
in the Fund's portfolio securities such that the Fund's net asset value per
share might be materially affected. The Fund reserves the right to calculate the
net asset value and to adjust the public offering price based thereon more
frequently than once a day if deemed desirable. The net asset value per share of
the different classes of shares are expected to be substantially the same; from
time to time, however, the per share net asset value of the different classes of
shares may differ.
 
  Portfolio securities are valued by using market quotations, prices provided by
market makers or estimates of market values obtained from yield data relating to
 
                                       34
<PAGE>   229
 
instruments or securities with similar characteristics in accordance with
procedures established in good faith by the Board of Trustees of the Trust, of
which the Fund is a series. Securities with remaining maturities of 60 days or
less are valued at amortized cost when amortized cost is determined in good
faith by or under the direction of the Board of Trustees of the Trust to be
representative of the fair value at which it is expected such securities may be
resold. Any securities or other assets for which current market quotations are
not readily available are valued at their fair value as determined in good faith
under procedures established by and under the general supervision of the Board
of Trustees of the Trust.
 
- ------------------------------------------------------------------------------
SHAREHOLDER SERVICES
- ------------------------------------------------------------------------------
 
  The Fund offers a number of shareholder services designed to facilitate
investment in its shares at little or no extra cost to the investor. Below is a
description of such services. Unless otherwise described below, each of these
services may be modified or terminated by the Fund at any time.
 
   
  INVESTMENT ACCOUNT. ACCESS, transfer agent for the Fund and a wholly-owned
subsidiary of Van Kampen American Capital, performs bookkeeping, data processing
and administration services related to the maintenance of shareholder accounts.
Each shareholder has an investment account under which shares are held by
ACCESS. Except as described in this Prospectus, after each share transaction in
an account, the shareholder receives a statement showing the activity in the
account. Each shareholder will receive statements at least quarterly from ACCESS
showing any reinvestments of dividends and capital gains distributions and any
other activity in the account since the preceding statement. Such shareholders
also will receive separate confirmations for each purchase or sale transaction
other than reinvestment of dividends and capital gains distributions and
systematic purchases or redemptions. Additions to an investment account may be
made at any time by purchasing shares through authorized brokers, dealers or
financial intermediaries or by mailing a check directly to ACCESS.
    
 
  SHARE CERTIFICATES. Generally, the Fund will not issue share certificates.
However, upon written or telephone request to the Fund, a share certificate will
be issued, representing shares (with the exception of fractional shares) of the
Fund. A shareholder will be required to surrender such certificates upon
redemption thereof. In addition, if such certificates are lost the shareholder
must write to Van Kampen American Capital Funds, c/o ACCESS, P.O. Box 418256,
Kansas City, MO 64141-9256, requesting an "affidavit of loss" and to obtain a
Surety Bond in a form acceptable to ACCESS. On the date the letter is received
ACCESS will calculate a fee for replacing the lost certificate equal to no more
than 2.00% of the net asset value of the issued shares and bill the party to
whom the replacement certificate was mailed.
 
  REINVESTMENT PLAN. A convenient way for investors to accumulate additional
shares is by accepting dividends and capital gains distributions in shares of
the
 
                                       35
<PAGE>   230
 
   
Fund. Such shares are acquired at net asset value (without sales charge) on the
record date of such dividend or distribution. Unless the shareholder instructs
otherwise, the reinvestment plan is automatic. This instruction may be made by
telephone by calling (800) 421-5666 ((800) 421-2833 for the hearing impaired) or
in writing to ACCESS. The investor may, on the initial application or prior to
any declaration, instruct that dividends be paid in cash and capital gains
distributions be reinvested at net asset value, or that both dividends and
capital gains distributions be paid in cash. For further information, see
"Distributions from the Fund."
    
 
  AUTOMATIC INVESTMENT PLAN. An automatic investment plan is available under
which a shareholder can authorize ACCESS to charge a bank account on a regular
basis to invest pre-determined amounts in the Fund. Additional information is
available from the Distributor or authorized brokers, dealers or financial
intermediaries.
 
   
  DIVIDEND DIVERSIFICATION. A shareholder may, upon written request or by
completing the appropriate section of the application form accompanied by this
Prospectus or by calling (800) 421-5666 ((800) 421-2833 for the hearing
impaired), elect to have all dividends and other distributions paid on a class
of shares of the Fund invested into shares of the same class of any other
Participating Fund, Tax Free Money Fund or Reserve Fund so long as a
pre-existing account for such class of shares exists for such shareholder.
    
 
  If the qualified pre-existing account does not exist, the shareholder must
establish a new account subject to minimum investment and other requirements of
the fund into which distributions would be invested. Distributions are invested
into the selected fund at its net asset value as of the payable date of the
distribution only if shares of such selected fund have been registered for sale
in the investor's state.
 
   
  EXCHANGE PRIVILEGE. Shares of the Fund may be exchanged with shares of another
Participating Fund subject to certain limitations. Before effecting an exchange,
shareholders in the Fund should obtain and read a current prospectus of the fund
into which the exchange is to be made. SHAREHOLDERS MAY ONLY EXCHANGE INTO SUCH
OTHER FUNDS AS ARE LEGALLY AVAILABLE FOR SALE IN THEIR STATE.
    
 
  To be eligible for exchange, shares of the Fund must have been registered in
the shareholder's name for at least 30 days prior to an exchange. Shares of the
Fund registered in a shareholder's name for less than 30 days may only be
exchanged upon receipt of prior approval of the Adviser. Under normal
circumstances, it is the policy of the Adviser not to approve such requests.
 
  Class A Shares of Van Kampen American Capital funds that generally impose an
initial sales charge are not subject to any sales charge upon exchange into the
Fund. Class A Shares of Van Kampen American Capital funds that generally do not
impose an initial sales charge are subject to the appropriate sales charge
applicable to Class A Shares of the Fund.
 
                                       36
<PAGE>   231
 
   
  No sales charge is imposed upon the exchange of Class B Shares and Class C
Shares. The CDSC schedule and conversion schedule applicable to a Class B Share
or Class C Share acquired through the exchange privilege is determined by
reference to the Van Kampen American Capital fund from which such share
originally was purchased. The holding period of a Class B Share or Class C Share
acquired through the exchange privilege is determined by reference to the date
such share originally was purchased from a Van Kampen American Capital fund.
    
 
  Exchanges of shares are sales and may result in a gain or loss for federal
income tax purposes. If the shares exchanged have been held for less than 91
days, the sales charge paid on such shares is not included in the tax basis of
the exchanged shares, but is carried over and included in the tax basis of the
shares acquired.
 
   
  A shareholder wishing to make an exchange may do so by sending a written
request to ACCESS or by contacting the telephone transaction line at (800)
421-5684 ((800) 421-2833 for the hearing impaired). A shareholder automatically
has telephone exchange privileges unless otherwise designated in the application
form accompanied by this Prospectus. The exchange will take place at the
relative net asset values of the shares next determined after receipt of such
request with adjustment for any additional sales charge. Any shares exchanged
begin earning dividends on the next business day after the exchange is affected.
Van Kampen American Capital and its subsidiaries, including ACCESS
(collectively, "VKAC"), and the Fund employ procedures considered by them to be
reasonable to confirm that instructions communicated by telephone are genuine.
Such procedures include requiring certain personal identification information
prior to acting upon telephone instructions, tape recording telephone
communications, and providing written confirmation of instructions communicated
by telephone. Exchanges are effected at the net asset value per share next
calculated after the request is received in good order with adjustment for any
additional sales charge. If reasonable procedures are employed, a shareholder
agrees that neither VKAC nor the Fund will be liable for following telephone
instructions which it reasonably believes to be genuine. VKAC and the Fund may
be liable for any losses due to unauthorized or fraudulent instructions if
reasonable procedures are not followed. If the exchanging shareholder does not
have an account in the fund whose shares are being acquired, a new account will
be established with the same registration, dividend and capital gains options
(except dividend diversification options) and broker, dealer or financial
intermediary of record as the account from which shares are exchanged, unless
otherwise specified by the shareholder. In order to establish a systematic
withdrawal plan for the new account or reinvest dividends from the new account
into another fund, an exchanging shareholder must file a specific written
request. The Fund reserves the right to reject any order to acquire shares
through exchange. In addition, the Fund may modify restrict or terminate the
exchange privilege at any time on 60 days' notice to its shareholders of any
termination or material amendment.
    
 
   
  A prospectus of any of these mutual funds may be obtained from any broker,
dealer or financial intermediary or the Distributor. An investor considering an
    
 
                                       37
<PAGE>   232
 
   
exchange to one of such funds should refer to the prospectus for additional
information regarding such fund prior to investing.
    
 
   
  SYSTEMATIC WITHDRAWAL PLAN. Any investor whose shares in a single account
total $10,000 or more at the offering price next computed after receipt of
instructions may establish a monthly, quarterly, semi-annual or annual
withdrawal plan. Any investor whose shares in a single account total $5,000 or
more at the offering price next computed after receipt of instructions may
establish a quarterly, semi-annual or annual withdrawal plan. This plan provides
for the orderly use of the entire account, not only the income but also the
capital, if necessary. Each withdrawal constitutes a redemption of shares on
which taxable gain or loss will be recognized. The plan holder may arrange for
monthly, quarterly, semi-annual, or annual checks in any amount not less than
$25.
    
 
   
  Holders of Class B Shares and Class C Shares who establish a withdrawal plan
may redeem up to 12% annually of the shareholder's initial account balance
without incurring a contingent deferred sales charge. Initial account balance
means the amount of the shareholder's investment at the time the election to
participate in the plan is made.
    
 
  Under the plan, sufficient shares of the Fund are redeemed to provide the
amount of the periodic withdrawal payment. Dividends and capital gains
distributions on shares held under the plan are reinvested in additional shares
at the next determined net asset value. If periodic withdrawals continuously
exceed reinvested dividends and capital gains distributions, the shareholder's
original investment will be correspondingly reduced and ultimately exhausted.
Withdrawals made concurrently with purchases of additional shares ordinarily
will be disadvantageous to the shareholder because of the duplication of sales
charges. The Fund reserves the right to amend or terminate the systematic
withdrawal program on thirty days' notice to its shareholders.
 
  CHECK WRITING PRIVILEGE. Holders of Class A Shares of the Fund for which
certificates have not been issued and which are in a non-escrow status may
appoint ACCESS as agent by completing the Authorization for Redemption by Check
Form and the appropriate section of the application and returning the form and
the application to ACCESS. Once the form is properly completed, signed and
returned to the agent, a supply of checks drawn on State Street Bank and Trust
Company ("State Street Bank") will be sent to such shareholder. These checks may
be made payable by the holder of Class A Shares to the order of any person in
any amount of $100 or more.
 
  When a check is presented to State Street Bank for payment, full and
fractional Class A Shares required to cover the amount of the check are redeemed
from the shareholder's account by ACCESS at the next determined net asset value.
Check writing redemptions represent the sale of Class A Shares. Any gain or loss
realized on the sale of Class A Shares is a taxable event. See "Redemption of
Shares."
 
                                       38
<PAGE>   233
 
   
  Checks will not be honored for redemption of Class A Shares held less than 15
calendar days, unless such Class A Shares have been paid for by bank wire. Any
Class A Shares for which there are outstanding certificates may not be redeemed
by check. If the amount of the check is greater than the proceeds of all
uncertificated shares held in the shareholder's Class A Share account, the check
will be returned and the shareholder may be subject to additional charges.
Holders of Class A Shares may not liquidate the entire account by means of a
check. The check writing privilege may be terminated or suspended at any time by
the Fund or State Street Bank. Retirement plans and accounts that are subject to
backup withholding are not eligible for the privilege. A "stop payment" system
is not available on these checks. See the Statement of Additional Information
for further information regarding the establishment of the privilege.
    
 
  AUTOMATED CLEARING HOUSE ("ACH") DEPOSITS. Holders of Class A Shares can use
ACH to have redemption proceeds deposited electronically into their bank
accounts. Redemptions transferred to a bank account via the ACH plan are
available to be credited to the account on the second business day following
normal payment. In order to utilize this option, the shareholder's bank must be
a member of Automated Clearing House. In addition, the shareholder must fill out
the appropriate section of the account application. The shareholder must also
include a voided check or deposit slip from the bank account into which
redemptions are to be deposited together with the completed application. Once
ACCESS has received the application and the voided check or deposit slip, such
shareholder's designated bank account, following any redemption, will be
credited with the proceeds of such redemption. Once enrolled in the ACH plan, a
shareholder may terminate participation at any time by writing ACCESS.
 
- ------------------------------------------------------------------------------
REDEMPTION OF SHARES
- ------------------------------------------------------------------------------
 
  Shareholders may redeem for cash some or all of their shares without charge by
the Fund (other than, with respect to CDSC Shares, the applicable contingent
deferred sales charge) at any time by sending a written request in proper form
directly to ACCESS, P. O. Box 418256, Kansas City, Missouri 64141-9256, by
placing the redemption request through an authorized dealer or by calling the
Fund.
 
  WRITTEN REDEMPTION REQUESTS. In the case of redemption requests sent directly
to ACCESS, the redemption request should indicate the number of shares to be
redeemed, the class designation of such shares, the account number and be signed
exactly as the shares are registered. Signatures must conform exactly to the
account registration. If the proceeds of the redemption would exceed $50,000, or
if the proceeds are not to be paid to the record owner at the record address, or
if the record address has changed within the previous 30 days, signature(s) must
be guaranteed by one of the following: a bank or trust company; a broker-dealer;
a credit union; a national securities exchange, registered securities
association or clearing agency; a savings and loan association; or a federal
savings bank. If
 
                                       39
<PAGE>   234
 
certificates are held for the shares being redeemed, such certificates must be
endorsed for transfer or accompanied by an endorsed stock power and sent with
the redemption request. In the event the redemption is requested by a
corporation, partnership, trust, fiduciary, executor or administrator, and the
name and title of the individual(s) authorizing such redemption is not shown in
the account registration, a copy of the corporate resolution or other legal
documentation appointing the authorized signer and certified within the prior 60
days must accompany the redemption request. The redemption price is the net
asset value per share next determined after the request is received by ACCESS in
proper form. Payment for shares redeemed (less any sales charge, if applicable)
will ordinarily be made by check mailed within three business days after
acceptance by ACCESS of the request and any other necessary documents in proper
order. Such payments may be postponed or the right of redemption suspended as
provided by the rules of the SEC. If the shares to be redeemed have been
recently purchased by check, ACCESS may delay mailing a redemption check until
it confirms that the purchase check has cleared, usually a period of up to 15
days. Any gain or loss realized on the redemption of shares is a taxable event.
 
  DEALER REDEMPTION REQUESTS. Shareholders may sell shares through their
securities dealer, who will telephone the request to the Distributor. Orders
received from dealers must be at least $500 unless transmitted via the FUNDSERV
network. The redemption price for such shares is the net asset value next
calculated after an order is received by a dealer provided such order is
transmitted to the Distributor prior to the Distributor's close of business on
such day. It is the responsibility of dealers to transmit redemption requests
received by them to the Distributor so they will be received prior to such time.
Any change in the redemption price due to failure of the Distributor to receive
a sell order prior to such time must be settled between the shareholder and
dealer. Shareholders must submit a written redemption request in proper form (as
described above under "Written Redemption Requests") to the dealer within three
business days after calling the dealer with the sell order. Payment for shares
redeemed (less any sales charge, if applicable) will ordinarily be made by check
mailed within three business days to the dealer.
 
   
  TELEPHONE REDEMPTION REQUESTS. The Fund permits redemption of shares by
telephone and for redemption proceeds to be sent to the address of record for
the account or to the bank account of record as described below. To establish
such privilege, a shareholder must complete the appropriate section of the
application accompanying this Prospectus or call the Fund at (800) 421-5666
((800) 421-2833 for the hearing impaired) to request that a copy of the
Telephone Redemption Authorization form be sent to them for completion. To
redeem shares, contact the telephone transaction line at (800) 421-5684. VKAC
and the Fund employ procedures considered by them to be reasonable to confirm
that instructions communicated by telephone are genuine. Such procedures include
requiring certain personal identification information prior to acting upon
telephone instructions, tape recording telephone communications, and providing
written confirmation of instructions communicated by telephone. If reasonable
procedures are employed, a
    
 
                                       40
<PAGE>   235
 
shareholder agrees that neither VKAC nor the Fund will be liable for following
instructions which it reasonably believes to be genuine. VKAC and the Fund may
be liable for any losses due to unauthorized or fraudulent instructions if
reasonable procedures are not followed. Telephone redemptions may not be
available if the shareholder cannot reach ACCESS by telephone, whether because
all telephone lines are busy or for any other reason; in such case, a
shareholder would have to use the Fund's other redemption procedures previously
described. Requests received by ACCESS prior to 4:00 p.m., New York time, on a
regular business day will be processed at the net asset value per share
determined that day. These privileges are available for all accounts other than
retirement accounts. The telephone redemption privilege is not available for
shares represented by certificates. If the shares to be redeemed have been
recently purchased by check, ACCESS may delay mailing a redemption check or
wiring redemption proceeds until it confirms that the purchase check has
cleared, usually a period of up to 15 days. If an account has multiple owners,
ACCESS may rely on the instructions of any one owner.
 
  For redemptions authorized by telephone, amounts of $50,000 or less may be
redeemed daily if the proceeds are to be paid by check sent to the shareholders'
address of record and amounts of at least $1,000 and up to $1 million may be
redeemed daily if the proceeds are to be paid by wire sent to the shareholder's
bank account of record. The proceeds must be payable to the shareholder(s) of
record. Proceeds from redemptions to be paid by check will ordinarily be mailed
within three business days to the shareholder's address of record. Proceeds from
redemptions to be paid by wire will ordinarily be wired on the next business day
to the shareholder's bank account of record. This privilege is not available if
the address of record has been changed within 30 days prior to a telephone
redemption request. The Fund reserves the right at any time to terminate, limit
or otherwise modify this telephone redemption privilege.
 
   
  REDEMPTION UPON DISABILITY. The Fund will waive the CDSC on redemptions
following the disability of holders of Class B Shares and Class C Shares. An
individual will be considered disabled for this purpose if he or she meets the
definition thereof in Section 72(m)(7) of the Code, which in pertinent part
defines a person as disabled if such person "is unable to engage in any
substantial gainful activity by reason of any medically determinable physical or
mental impairment which can be expected to result in death or to be of
long-continued and indefinite duration." While the Fund does not specifically
adopt the balance of the Code's definition which pertains to furnishing the
Secretary of Treasury with such proof as he or she may require, the Distributor
will require satisfactory proof of disability before it determines to waive the
CDSC on Class B Shares and Class C Shares.
    
 
   
  In cases of disability, the CDSCs on Class B Shares and Class C Shares will be
waived where the disabled person is either an individual shareholder or owns the
shares as a joint tenant with right of survivorship or is the beneficial owner
of a custodial or fiduciary account, and where the redemption is made within one
year of the initial determination of disability. This waiver of the CDSC on
Class B Shares
    
 
                                       41
<PAGE>   236
 
and Class C Shares applies to a total or partial redemption, but only to
redemptions of shares held at the time of the initial determination of
disability.
 
   
  GENERAL REDEMPTION INFORMATION. The Fund may redeem any shareholder account
with a net asset value on the date of the notice of redemption less than the
minimum investment as specified by the Trustees. At least 60 days advance
written notice of any such involuntary redemption is required and the
shareholder is given an opportunity to purchase the required value of additional
shares at the next determined net asset value without sales charge. Any
applicable CDSC will be deducted from the proceeds of this redemption. Any
involuntary redemption may only occur if the shareholder account is less than
the minimum investment due to shareholder redemptions.
    
 
   
  REINSTATEMENT PRIVILEGE. Holders of Class A Shares or Class B Shares who have
redeemed shares of the Fund may reinstate any portion or all of the net proceeds
of such redemption in Class A Shares of the Fund. Holders of Class C Shares who
have redeemed shares of the Fund may reinstate any portion or all of the net
proceeds of such redemption in Class C Shares of the Fund with credit given for
any CDSC paid upon such redemption. Such reinstatement is made at the net asset
value (without sales charge except as described under "Shareholder Services --
Exchange Privilege") next determined after the order is received, which must be
within 180 days after the date of the redemption. See "Purchase of Shares --
Waiver of Contingent Deferred Sales Charge." Reinstatement at net asset value is
also offered to participants in those eligible retirement plans held or
administered by Van Kampen American Capital Trust Company for repayment of
principal (and interest) on their borrowings on such plans.
    
 
- ------------------------------------------------------------------------------
   
DISTRIBUTION AND SERVICE PLANS
    
- ------------------------------------------------------------------------------
 
  The Fund has adopted a distribution plan (the "Distribution Plan") with
respect to each class of its shares pursuant to Rule 12b-1 under the 1940 Act.
The Fund also has adopted a service plan (the "Service Plan") with respect to
each class of its shares. The Distribution Plan and the Service Plan provide
that the Fund may spend a portion of the Fund's average daily net assets
attributable to each class of shares in connection with distribution of the
respective class of shares and in connection with the provision of ongoing
services to shareholders of each class. The Distribution Plan and the Service
Plan are being implemented through an agreement with the Distributor and
sub-agreements between the Distributor and brokers, dealers and financial
intermediaries (collectively, "Selling Agreements") that may provide for their
customers or clients certain services or assistance.
 
  CLASS A SHARES. The Fund may spend an aggregate amount of up to 0.25% per year
of the average daily net assets attributable to the Class A Shares of the Fund
pursuant to the Distribution Plan and the Service Plan. From such amount, the
Fund may spend up to 0.25% per year of its average daily net assets attributable
to the Class A Shares pursuant to the Service Plan in connection with the
ongoing
 
                                       42
<PAGE>   237
 
   
provision of services to holders of such shares by the Distributor and by
brokers, dealers or financial intermediaries and in connection with the
maintenance of shareholders' accounts. The Fund pays the Distributor the lesser
of the balance of the 0.25% not paid to such brokers, dealers or financial
intermediaries or the amount of the Distributor's actual distribution-related
expenses.
    
 
  CLASS B SHARES. The Fund may spend up to 0.75% per year of its average daily
net assets attributable to the Class B Shares pursuant to the Distribution Plan.
In addition, the Fund may spend up to 0.25% per year of the Fund's average daily
net assets attributable to the Class B Shares pursuant to the Service Plan in
connection with the ongoing provision of services to holders of such shares by
the Distributor and by brokers, dealers or financial intermediaries and in
connection with the maintenance of such shareholders' accounts.
 
   
  CLASS C SHARES. The Fund may spend up to 0.75% per year of the average daily
net assets attributable to the Class C Shares of the Fund pursuant to the
Distribution Plan. From such amount, the Fund, or the Distributor as agent for
the Fund, pays brokers, dealers or financial intermediaries in connection with
the distribution of the Class C Shares up to 0.75% of the Fund's average daily
net assets attributable to Class C Shares maintained in the Fund more than one
year by such broker's, dealer's or financial intermediary's customers. The Fund
pays the Distributor the lesser of the balance of 0.75% not paid to such
brokers, dealers or financial intermediaries or the amount of the Distributor's
actual distribution-related expense attributable to the Class C Shares. In
addition, the Fund may spend up to 0.25% per year of the Fund's average daily
net assets attributable to the Class C Shares pursuant to the Service Plan in
connection with the ongoing provision of services to holders of such shares by
the Distributor and by brokers, dealers or financial intermediaries and in
connection with the maintenance of such shareholders' accounts.
    
 
  OTHER INFORMATION. Amounts payable to the Distributor with respect to the
Class A Shares under the Distribution Plan in a given year may not fully
reimburse the Distributor for its actual distribution-related expenses during
such year. In such event, with respect to the Class A Shares, there is no
carryover of such reimbursement obligations to succeeding years.
 
   
  The Distributor's actual expenses with respect to the CDSC Shares (for
purposes of this section, excluding any Class A Shares that may be subject to a
CDSC) for any given year may exceed the amounts payable to the Distributor with
respect to the CDSC Shares under the Distribution Plan, the Service Plan and
payments received pursuant to the CDSC. In such event, with respect to the CDSC
Shares, any unreimbursed expenses will be carried forward and paid by the Fund
(up to the amount of the actual expenses incurred) in future years so long as
such Distribution Plan is in effect. Except as mandated by applicable law, the
Fund does not impose any limit with respect to the number of years into the
future that such unreimbursed distribution expenses may be carried forward (on a
Fund level basis). Because such expenses are accounted on a Fund level basis, in
periods of extreme net asset value
    
 
                                       43
<PAGE>   238
 
   
fluctuation such amounts with respect to a particular CDSC Share may be greater
or less than the amount of the initial commission (including carrying cost) paid
by the Distributor with respect to such CDSC Share. In such circumstances, a
shareholder of such CDSC Share may be deemed to incur expenses attributable to
other shareholders of such class. As of December 31, 1996, there were $111,106
and $25,606 of unreimbursed distribution related expenses with respect to Class
B Shares and Class C Shares, respectively, representing 0.68% and less than
0.44% of the Fund's net assets attributable to Class B Shares and Class C
Shares, respectively. If the Distribution Plan was terminated or not continued,
the Fund would not be contractually obligated to pay the Distributor for any
expenses not previously reimbursed by the Fund or recovered through CDSCs.
    
 
   
  Because the Fund is a series of the Trust, amounts paid to the Distributor as
reimbursement for expenses of one series of the Trust may indirectly benefit the
other funds which are series of the Trust. The Distributor will endeavor to
allocate such expenses among such funds in an equitable manner. The Distributor
will not use the proceeds from the CDSC with respect to a particular class of
shares to defray distribution-related expenses attributable to any other class
of shares. Various federal and state laws prohibit national banks and some
state-chartered commercial banks from underwriting or dealing in the Fund's
shares. In addition, state securities laws on this issue may differ from the
interpretations of federal law, and banks and financial institutions may be
required to register as dealers pursuant to state law. In the unlikely event
that a court were to find that these laws prevent such banks from providing such
services described above, the Fund would seek alternate providers and expects
that shareholders would not experience any disadvantage.
    
 
- ------------------------------------------------------------------------------
DISTRIBUTIONS FROM THE FUND
- ------------------------------------------------------------------------------
 
  The Fund's present policy, which may be changed at any time by the Board of
Trustees, is to declare daily and pay monthly distributions of all or
substantially all net investment income of the Fund. Net investment income
consists of all interest income, dividends and other ordinary income earned by
the Fund, less all expenses of the Fund attributable to the class of shares in
question. Net short-term capital gains, if any, may be distributed throughout
the year. Expenses of the Fund are accrued each day. Net realized long-term
capital gains, if any, are expected to be distributed, to the extent permitted
by applicable law, to shareholders at least annually. Distributions cannot be
assured, and the amount of each monthly distribution may vary.
 
  Distributions with respect to each class of shares will be calculated in the
same manner on the same day and will be in the same amount, except that the
different distribution and service fees and any incremental administrative
expenses relating to each class of shares will be borne exclusively by the
respective class and may cause the distributions relating to the different
classes of shares to differ. Generally,
 
                                       44
<PAGE>   239
 
distributions with respect to a class of shares subject to a higher distribution
fee, service fee, or, where applicable, the conversion feature will be lower
than distributions with respect to a class of shares subject to a lower
distribution fee, service fee, or not subject to the conversion feature.
 
   
  Investors will be entitled to begin receiving dividends on their shares on the
business day after ACCESS receives payments for such shares. However, shares
become entitled to dividends on the day ACCESS receives payment for the shares
either through a fed wire or NSCC settlement. Shares remain entitled to
dividends through the day such shares are processed for payment on redemption.
    
 
  Distribution checks may be sent to parties other than the shareholder in whose
name the account is registered. Persons wishing to utilize this service should
complete the appropriate section of the account application accompanying this
Prospectus or available from Van Kampen American Capital Funds, c/o ACCESS, P.O.
Box 418256, Kansas City, MO 64141-9256. After ACCESS receives this completed
form, distribution checks will be sent to the bank or other person so designated
by such shareholder.
 
   
  PURCHASE OF ADDITIONAL SHARES WITH DISTRIBUTIONS.  The Fund will automatically
credit monthly distributions and any annual net long-term capital gain
distributions to a shareholder's account in additional shares of the Fund valued
at net asset value, without a sales charge. Unless a shareholder instructs
otherwise, the reinvestment plan is automatic. This instruction may be made by
telephone by calling (800) 421-5666 ((800) 421-2833 for the hearing impaired) or
in writing to ACCESS. See "Shareholder Services -- Reinvestment Plan."
    
 
- ------------------------------------------------------------------------------
   
TAX STATUS
    
- ------------------------------------------------------------------------------
 
   
  FEDERAL INCOME TAXATION.  The Fund has qualified and intends to continue to
qualify each year and to elect to be treated as a regulated investment company
under Subchapter M of the Code. To qualify as a regulated investment company,
the Fund must comply with certain requirements of the Code relating to, among
other things, the source of its income and diversification of its assets.
    
 
   
  If the Fund so qualifies and distributes each year to its shareholders at
least 90% of its net investment income (including tax-exempt interest, taxable
income and net short-term capital gain, but not net capital gains, which are the
excess of net long-term capital gains over net short-term capital losses), it
will not be required to pay federal income taxes on any income distributed to
shareholders. The Fund intends to distribute at least the minimum amount of net
investment income necessary to satisfy the 90% distribution requirement. The
Fund will not be subject to federal income tax on any net capital gains
distributed to shareholders.
    
 
   
  In order to avoid a 4% excise tax, the Fund will be required to distribute, by
December 31 of each year, at least 98% of its ordinary income (not including
    
 
                                       45
<PAGE>   240
 
   
tax-exempt income) for such year and at least 98% of its capital gain net income
(the latter of which generally is computed on the basis of the one-year period
ending on October 31 of such year), plus any amounts that were not distributed
in previous taxable years. For purposes of the excise tax, any ordinary income
or capital gain net income retained by, and subject to federal income tax in the
hands of, the Fund will be treated as having been distributed.
    
 
   
  If the Fund failed to qualify as a regulated investment company or failed to
satisfy the 90% distribution requirement in any taxable year, the Fund would be
taxed as an ordinary corporation on its taxable income (even if such income were
distributed to its shareholders) and all distributions out of earnings and
profits would be taxed to shareholders as ordinary income. To qualify again as a
regulated investment company in a subsequent year, the Fund may be required to
pay an interest charge on 50% of its earnings and profits attributable to
non-regulated investment company years and would be required to distribute such
earnings and profits to shareholders (less any interest charge). In addition, if
the Fund failed to qualify as a regulated investment company for its first
taxable year or, if immediately after qualifying as a regulated investment
company for any taxable year, it failed to qualify for a period greater than one
taxable year, the Fund would be required to recognize any net built-in gains
(the excess of aggregate gains, including items of income, over aggregate losses
that would have been realized if it had been liquidated) in order to qualify as
a regulated investment company in a subsequent year.
    
 
   
  Some of the Fund's investment practices are subject to special provisions of
the Code that, among other things, may defer the use of certain losses of the
Fund and affect the holding period of the securities held by the Fund and the
character of the gains or losses realized by the Fund. These provisions may also
require the Fund to mark-to-market some of the positions in its portfolio (i.e.,
treat them as if they were sold for fair market value at the end of the
tax-year), which may cause the Fund to recognize income without receiving cash
with which to make distributions in amounts necessary to satisfy the 90%
distribution requirement and the distribution requirements for avoiding income
and excise taxes. The Fund will monitor its transactions and may make certain
tax elections in order to mitigate the effect of these rules and prevent
disqualification of the Fund as a regulated investment company.
    
 
   
  The Fund's ability to dispose of portfolio securities may be limited by the
requirement for qualification as a regulated investment company that less than
30% of the Fund's annual gross income be derived from the disposition of
securities held for less than three months.
    
 
   
  Investments of the Fund in securities issued at a discount or providing for
deferred interest or payment of interest in kind are subject to special tax
rules that will affect the amount, timing and character of distributions to
shareholders. For example, with respect to securities issued at a discount, the
Fund will be required to accrue as income each year a portion of the discount
and to distribute such income
    
 
                                       46
<PAGE>   241
 
   
each year in order to maintain its qualification as a regulated investment
company and to avoid income and excise taxes. In order to generate sufficient
cash to make distributions necessary to satisfy the 90% distribution requirement
and to avoid income and excise taxes, the Fund may have to dispose of securities
that it would otherwise have continued to hold. A portion of the discount
relating to certain stripped tax-exempt obligations may constitute taxable
income when distributed to shareholders.
    
 
   
  DISTRIBUTIONS.  The Fund intends to invest in sufficient tax-exempt municipal
securities to permit payment of "exempt-interest dividends" (as defined in the
Code). Dividends paid by the Fund from the net tax-exempt interest earned from
municipal securities qualify as exempt-interest dividends if, at the close of
each quarter of its taxable year, at least 50% of the value of the total assets
of the Fund consists of municipal securities.
    
 
   
  The Tax Reform Act of 1986 (the "Tax Reform Act") may have an adverse impact
upon the Fund and its shareholders. The Tax Reform Act imposed new limitations
on the use and investment of the proceeds of state and local government bonds
and other funds, which limitations must be satisfied in order to maintain the
exclusion from gross income for interest on such bonds. The provisions of the
Tax Reform Act generally apply to bonds issued after August 15, 1986. In light
of these requirements, bond counsel qualify their opinions as to the federal tax
status of bonds issued after August 15, 1986 by making them contingent on the
issuer's future compliance with these limitations. Any failure on the part of an
issuer to comply could cause the interest on its bonds to become taxable to
investors retroactive to the date the bonds were issued.
    
 
   
  Except as provided below, exempt-interest dividends paid to shareholders
generally are not includable in the shareholders' gross income for federal
income tax purposes. The percentage of the total dividends paid by the Fund
during any taxable year that qualify as exempt-interest dividends will be the
same for all shareholders of the Fund receiving dividends during such year.
    
 
   
  The Tax Reform Act also makes interest on certain "private-activity bonds" an
item of tax preference subject to the alternative minimum tax on individuals and
corporations. The Fund invests a portion of its assets in municipal securities
subject to this provision so that a portion of its exempt-interest dividends is
an item of tax preference to the extent such dividends represent interest
received from these private-activity bonds. Accordingly, investment in the Fund
could cause shareholders to be subject to (or result in an increased liability
under) the alternative minimum tax. The Tax Reform Act also imposed per capita
volume limitations on certain private-activity bonds which could limit the
amount of such bonds available for investment by the Fund.
    
 
   
  Exempt-interest dividends are included in determining what portion, if any, of
a person's social security and railroad retirement benefits will be includable
in gross income subject to federal income tax.
    
 
                                       47
<PAGE>   242
 
   
  Although exempt-interest dividends generally may be treated by Fund
shareholders as items of interest excluded from their gross income, each
shareholder is advised to consult his tax adviser with respect to whether
exempt-interest dividends retain this exclusion if the purchaser would be
treated as a "substantial user" (or a "related person" of a substantial user) of
the facilities financed with respect to any of the tax-exempt obligations held
by the Fund, or by the Trust if it is required to qualify as a regulated
investment company as described below. "Substantial user" is defined under U.S.
Treasury Regulations to include a non-exempt person who regularly uses in his
trade or business a part of any facilities financed with the tax-exempt
obligations and whose gross revenues derived from such facilities exceed five
percent of the total revenues derived from the facilities by all users, or who
occupies more than 5% of the useable area of the facilities or for whom the
facilities or a part thereof were specifically constructed, reconstructed or
acquired. Examples of "related persons" include certain related natural persons,
affiliated corporations, a partnership and its partners and an S corporation and
its shareholders.
    
 
   
  The Omnibus Budget Reconciliation Act of 1993 included certain provisions that
requires gains on dispositions of tax-exempt securities purchased at a market
discount be treated as ordinary income to the extent of the accrued market
discount, if the securities are acquired after April 30, 1993. Such securities
were exempt from the market discount rules under prior law. Interest on
indebtedness incurred or continued by a shareholder to purchase or carry shares
of the Fund is not deductible for federal income tax purposes if the Fund
distributes exempt-interest dividends during the shareholder's taxable year. If
a shareholder receives an exempt-interest dividend with respect to any shares
and such shares are held for six months or less, any short-term capital loss on
the sale or exchange of the shares will be disallowed to the extent of the
amount of such exempt-interest dividend.
    
 
   
  While the Fund expects that a major portion of its net investment income will
constitute tax-exempt interest, a significant portion may consist of investment
company taxable income. Distributions of the Fund's net investment company
taxable income are taxable to shareholders as ordinary income to the extent of
the Fund's earnings and profits, whether paid in cash or reinvested in
additional shares. Distributions of the Fund's net capital gains ("capital gains
dividends"), if any, are taxable to shareholders as long-term capital gains
regardless of the length of time shares of the Fund have been held by such
shareholders. Interest on indebtedness which is incurred to purchase or carry
shares of a mutual fund which distributes exempt-interest dividends during the
year is not deductible for federal income tax purposes. Distributions in excess
of the Fund's earnings and profits will first reduce the adjusted tax basis of a
holder's shares and, after such adjusted tax basis is reduced to zero, will
constitute capital gains to such holder (assuming such shares are held as a
capital asset). Tax-exempt shareholders not subject to federal income tax on
their income generally will not be taxed on distributions from the Fund.
    
 
   
  Shareholders receiving distributions in the form of additional shares issued
by the Fund will be treated for federal income tax purposes as receiving a
distribution in an
    
 
                                       48
<PAGE>   243
 
   
amount equal to the fair market value of the shares received, determined as of
the distribution date. The basis of such shares will equal the fair market value
on the distribution date.
    
 
   
  The Fund will inform shareholders of the source and tax status of all
distributions promptly after the close of each calendar year. The aggregate
amount of dividends so designated cannot exceed, however, the amount of interest
exempt from tax under Section 103 of the Code received by the Fund during the
year over any amounts disallowed as deductions under Sections 265 and 171(a)(2)
of the Code. Since the percentage of dividends which are "exempt-interest"
dividends is determined on an average annual method for the fiscal year, the
percentage of income designated as tax-exempt for any particular dividend may be
substantially different from the percentage of the Fund's income that was tax
exempt during the period covered by the dividend, Fund distributions generally
will not qualify for the dividends received deduction for corporations.
    
 
   
  Although dividends generally will be treated as distributed when paid,
dividends declared in October, November or December, payable to shareholders of
record on a specified date in such month and paid during January of the
following year will be treated as having been distributed by the Fund and
received by the shareholders on the December 31 prior to the date of payment. In
addition, certain other distributions made after the close of a taxable year of
the Fund may be "spilled back" and treated as paid by the Fund (except for
purposes of the 4% excise tax) during such taxable year. In such case,
shareholders will be treated as having received such dividends in the taxable
year in which the distribution was actually made.
    
 
   
  The Fund is required, in certain circumstances, to withhold 31% of dividends
and certain other payments, including redemptions, paid to shareholders who do
not furnish to the Fund their correct taxpayer identification number (in the
case of individuals, their social security number) and certain required
certifications or who are otherwise subject to backup withholding.
    
 
   
  SALE OF SHARES.  The sale of shares (including transfers in connection with a
redemption or repurchase of shares) will be a taxable transaction for federal
income tax purposes. Selling shareholders will generally recognize gain or loss
in an amount equal to the difference between their adjusted tax basis in the
shares and the amount received. If such shares are held as a capital asset, the
gain or loss will be a capital gain or loss and will be long-term if such shares
have been held for more than one year. Any loss realized upon a taxable
disposition of shares held for six months or less will be treated as a long-term
capital loss to the extent of any capital gains dividends received with respect
to such shares. For purposes of determining whether shares have been held for
six months or less, the holding period is suspended for any periods during which
the shareholder's risk of loss is diminished as a result of holding one or more
other positions in substantially similar or related property or through certain
options or short sales.

  STATE AND LOCAL TAXES.  The exemption of interest income for federal income
tax purposes may not result in similar exemptions under the laws of a particular
state or local taxing authority. Income distributions may be taxable to
shareholders under state or local law as dividend income even though a portion
of such distributions may be derived from interest on tax-exempt obligations
which, if realized directly, would be exempt from such income taxes. It is
recommended that investors consult their tax advisers for information in this
regard. The Fund will report annually to its shareholders the percentage and
source, on a state-by-state basis, of interest income earned on municipal
securities received by the Fund during the preceding calendar year. Dividends
and distributions paid by the Fund from sources other than tax-exempt interest
are generally subject to taxation at the state and local levels.
    
 
   
  GENERAL.  The federal, state and local income tax discussion set forth above
is for general information only. Prospective investors should consult their
advisors regarding the specific federal tax consequences of holding and
disposing of shares, as well as the effects of state, local and foreign tax law
and any proposed tax law changes.

FUND PERFORMANCE
    
- ------------------------------------------------------------------------------
 
   
  From time to time advertisements and other sales materials for the Fund may
include information concerning the historical performance of the Fund. Any such
information will include the average total return of the Fund calculated on a
compounded basis for specified periods of time. Such advertisements and sales
material may also include a yield quotation as of a current period. In each
case, such total return and yield information, if any, will be calculated
pursuant to rules established by the SEC and will be computed separately for
each class of the Fund's Shares. In lieu of or in addition to total return and
yield calculations, such information may include performance rankings and
similar information from independent organizations such as Lipper Analytical
Services, Inc. or nationally recognized financial publications. From time to
time, the Fund may compare its performance to certain securities and unmanaged
indices which may have different risk/reward characteristics than the Fund. Such
characteristics may include, but are not limited to, tax features, guarantees,
insurance and fluctuation of principal and/or return. In addition, from time to
time, the Fund may utilize sales literature that includes hypotheticals.
    
 
  From time to time, the Fund may include in its sales literature and
shareholder reports a quotation of the current "distribution rate" for each
class of shares of the Fund. Distribution rate is a measure of the level of
income and short-term capital gain dividends, if any, distributed for a
specified period. Distribution rate is determined by annualizing the
distributions per share for a stated period and dividing the result by the
public offering price for the same period. It differs from yield, which is a
measure of the income actually earned by the Fund's investments, and from total
return, which is a measure of the income actually earned by the
 
                                       50
<PAGE>   245
 
   
Fund's investments plus the effect of any realized and unrealized appreciation
or depreciation of such investments during a stated period. Distribution rate
is, therefore, not intended to be a complete measure of the Fund's performance.
Distribution rate may sometimes be greater than yield since, for instance, it
may not include the effect of amortization of bond premiums, and may include
non-recurring short-term capital gains and premiums from futures transactions
engaged in by the Fund. Distribution rates will be computed separately for each
class of the Fund's Shares.
    
 
   
  Further information about the Fund's performance is contained in the Fund's
Annual Report and the Fund's Statement of Additional Information, each of which
can be obtained without charge by calling (800) 421-5666 ((800) 421-2833 for the

- ------------------------------------------------------------------------------
DESCRIPTION OF SHARES OF THE FUND
- ------------------------------------------------------------------------------
 
  The Fund is a series of the Van Kampen American Capital Tax Free Trust, a
Delaware business trust organized as of May 10, 1995 (the "Trust"). The Fund was
originally organized in 1993 under the name Van Kampen Merritt Limited Term
Municipal Income Fund as a sub-trust of Van Kampen Merritt Tax Free Fund, a
Massachusetts business trust. The Fund was reorganized as a series of the Trust
as of July 31, 1995. Shares of the Trust entitle their holders to one vote per
share; however, separate votes are taken by each series on matters affecting an
individual series.
 
   
  The authorized capitalization of the Fund consists of an unlimited number of
shares of beneficial interest, $0.01 par value, divided into three classes,
designated Class A Shares, Class B Shares and Class C Shares. Each class of
shares represent an interest in the same assets of the Fund and are identical in
all respects except that each class bears certain distribution expenses and has
exclusive voting rights with respect to its distribution fee. See "Distribution
and Service Plans."
    
 
   
  The Fund is permitted to issue an unlimited number of classes of shares. Each
class of shares is equal as to earnings, assets and voting privileges, except as
noted above, and each class bears the expenses related to the distribution of
its shares. There are no conversion, preemptive or other subscription rights,
except with respect to the conversion of Class B Shares and certain Class C
Shares into Class A Shares as described above. In the event of liquidation, each
of the shares of the Fund is entitled to its portion of all of the Fund's net
assets after all debt and expenses of the Fund have been paid. Since Class B
Shares and Class C Shares pay higher distribution expenses, the liquidation
proceeds to holders of Class B Shares and Class C Shares are likely to be lower
than to holders of Class A Shares.
    
 
  The Trust does not contemplate holding regular meetings of shareholders to
elect Trustees or otherwise. However, the holders of 10% or more of the
outstanding shares may by written request require a meeting to consider the
removal of Trustees
 
                                       51
<PAGE>   246
 
by a vote of two-thirds of the shares then outstanding cast in person or by
proxy at such meeting. The Trust will assist such holders in communicating with
other shareholders of the Fund to the extent required by the 1940 Act. More
detailed information concerning the Trust is set forth in the Statement of
Additional Information.

                               PROSPECTUS SUMMARY
- ------------------------------------------------------------------------------
 
THE FUND.  Van Kampen American Capital Florida Insured Tax Free Income Fund (the
"Fund") is a non-diversified mutual fund, organized as a separate series of Van
Kampen American Capital Tax Free Trust. See "The Fund."
 
INVESTMENT OBJECTIVE.  The Fund's investment objective is to provide investors
with a high level of current income exempt from federal income tax and Florida
intangible personal property taxes, consistent with preservation of capital. The
Fund is designed for investors who are residents of Florida for tax purposes.
 
INVESTMENT POLICIES.  Under normal market conditions, the Fund seeks to achieve
its investment objective by investing at least 80% of its assets in a portfolio
of Florida municipal securities that are insured as to timely payment of both
principal and interest by an entity whose claims-paying ability is rated AAA by
Standard & Poor's Ratings Group ("S&P") or Aaa by Moody's Investors Service,
Inc. ("Moody's") or an equivalent rating from another nationally recognized
statistical rating organization ("NRSRO"). Up to 20% of the Fund's total assets
may consist of uninsured Florida municipal securities rated investment grade at
the time of investment. Investment grade securities are securities rated BBB or
higher by S&P or Baa or higher by Moody's or an equivalent rating from another
NRSRO. Up to 20% of the Fund's assets may be invested in municipal securities
that are subject to federal alternative minimum tax. See "Investment Objectives
and Policies," "Municipal Securities" and "Special Considerations Regarding the
Fund."
 
INVESTMENT RESULTS.  The investment results of the Fund are shown in the table
of "Financial Highlights."
 
PURCHASE OF SHARES.  Shares of the Fund are offered through Van Kampen American
Capital Distributors, Inc. (the "Distributor"), as principal underwriter, and
through selected brokers and dealers. The offering price is the net asset value
per share next determined following receipt of an order plus a sales charge
which, at the option of the investor, may be imposed at the time of purchase or
on a contingent deferred basis. Investors may elect to purchase Class A Shares,
Class B Shares or Class C Shares, each with different sales charges and
expenses. The minimum initial investment is $500 for each class of shares and
the minimum subsequent investment is $25 for each class of shares (or less as
described under "Purchase of Shares"). The different classes of shares permit an
investor to choose the method of purchasing shares that is more beneficial to
the investor, taking into account the amount of the purchase, the length of time
the investor expects to hold the shares and other circumstances. See "Purchase
of Shares."
 
   
INVESTMENT ADVISER.  Van Kampen American Capital Investment Advisory Corp. (the
"Adviser") is the Fund's investment adviser.
    
 
                                        3
<PAGE>   252
 
SPECIAL RISK FACTORS.  The Fund may invest up to 20% of its assets in certain
derivative securities such as inverse floaters. Investment in such derivative
securities involves significant risks. Under normal market conditions, the Fund
will invest substantially all of its assets in insured Florida municipal
securities, and therefore it will be more susceptible to factors adversely
affecting issuers of Florida municipal securities than a municipal securities
fund that does not invest in Florida municipal securities to this degree. There
can be no assurance that the Fund will achieve its objective. See "Special
Considerations Regarding the Fund."
 
   
  The foregoing is qualified in its entirety by reference to the more detailed
    
              information appearing elsewhere in this Prospectus.

(1) Expenses include a waiver of $171,268 of "Management fees" and assumption of
    $235,222 of "Other expenses" by the Adviser. If the Adviser did not waive
    fees for the fiscal year ending December 31, 1996, the "Management fees"
    would have been 0.50% for each class of shares, "Other expenses" would have
    been 0.72% for each class of shares and "Total expenses" would have been
    1.47% for Class A Shares, 2.22% for Class B Shares and 2.22% for Class C
    Shares.
    
 
   
(2) Includes a service fee of up to 0.25% (as a percentage of net asset value)
    paid by the Fund as compensation for ongoing services rendered to investors.
    With respect to each class of shares, amounts in excess of 0.25%, if any,
    represent an asset based sales charge. The asset based sales charge with
    respect to Class C Shares includes 0.75% (as a percentage of net asset
    value) paid to investors' broker-dealers as sales compensation.

* Based on conversion to Class A Shares after eight years.
    
 
   
  The purpose of the foregoing table is to assist an investor in understanding
the various costs and expenses that an investor in the Fund will bear directly
or indirectly. The "Example" reflects expenses based on the "Annual Fund
Operating Expenses" table as shown above carried out to future years. As Fund
assets increase, the fees waived or expenses reimbursed by the Adviser are
expected to decrease. Accordingly, it is unlikely that future expenses as
projected will remain consistent with those determined based on the "Annual Fund
Operating Expenses" table. The ten year amount with respect to Class B Shares of
the Fund reflects the lower aggregate 12b-1 and service fees applicable to such
shares after conversion to Class A Shares. THE INFORMATION CONTAINED IN THE
ABOVE TABLE SHOULD NOT BE CONSIDERED A REPRESENTATION OF PAST OR FUTURE EXPENSES
AND ACTUAL EXPENSES MAY BE GREATER OR LESSER THAN THOSE SHOWN. For a more
complete description of such costs and expenses, see "Purchase of Shares,"
"Redemption of Shares," "Investment Advisory Services" and "Distribution and
Service Plans."

THE FUND
- ------------------------------------------------------------------------------
 
  Van Kampen American Capital Florida Insured Tax Free Income Fund (the "Fund")
is a non-diversified, separate series of Van Kampen American Capital Tax Free
Trust (the "Trust"), an open-end management investment company, commonly known
as a "mutual fund," organized as a Delaware business trust. Mutual funds sell
their shares to investors and invest the proceeds in a portfolio of securities.
A mutual fund allows investors to pool their money with that of other investors
in order to obtain professional investment management. Mutual funds generally
make it possible for investors to obtain greater diversification of their
investments and to simplify their recordkeeping.
 
  Van Kampen American Capital Investment Advisory Corp. (the "Adviser") provides
investment advisory and administrative services to the Fund. The Adviser and its
affiliates act as investment adviser to other mutual funds distributed by Van
Kampen American Capital Distributors, Inc. ("the Distributor"). To obtain
prospectuses and other information on any of these other funds, please call the
telephone number on the cover page of the Prospectus.
 
- ------------------------------------------------------------------------------
INVESTMENT OBJECTIVE AND POLICIES
- ------------------------------------------------------------------------------
 
  The investment objective of the Fund is to provide investors a high level of
current income exempt from federal income tax and Florida intangible personal
property taxes, consistent with preservation of capital. The Fund is designed
for investors who are residents of Florida for tax purposes. The Fund's
investment objective is a fundamental policy and may not be changed without
shareholder approval of the holders of a majority of the Fund's outstanding
voting securities, as defined in the Investment Company Act of 1940, as amended
(the "1940 Act"). Under normal market conditions, the Fund will invest up to 80%
of its assets in Florida municipal securities that are insured as to timely
payment of both principal and interest by an entity whose claims-paying ability
is rated AAA by Standard & Poor's Ratings Group ("S&P") or Aaa by Moody's
Investors Service, Inc. ("Moody's") or an equivalent rating from another
nationally recognized statistical rating organization ("NRSRO"). Up to 20% of
the Fund's total assets may consist of uninsured Florida municipal securities
rated investment grade at the time of investment. Investment grade securities
are securities rated BBB or higher by S&P or Baa or higher by Moody's, or an
equivalent rating by another NRSRO. There are market risks inherent in all
investments in securities; and accordingly there can be no assurance the Fund
will achieve its investment objective. An investment in the Fund may not be
appropriate for all investors. The Fund is not intended to be a complete
investment program, and investors should consider their long-term investment
goals and financial needs when making an investment decision with respect to the
Fund. An investment in the Fund is intended to be a long-term investment and
should not be used as a trading vehicle.
 
                                        9
<PAGE>   258
 
  For a description of S&P's and Moody's claims-paying ability ratings and
municipal securities ratings see the Statement of Additional Information. From
time to time, the Fund temporarily may invest up to 10% of its assets in tax
exempt money market funds. Such instruments will be treated as investments in
municipal securities.
 
  SELECTION OF INVESTMENTS. The Adviser will buy and sell securities for the
Fund's portfolio with a view to seeking a high level of current income exempt
from federal income tax and Florida intangible personal property taxes and will
select securities which the Adviser believes entail reasonable credit risk
considered in relation to the investment policies of the Fund. As a result, the
Fund will not necessarily invest in the highest yielding Florida municipal
securities permitted by its investment policies if the Adviser determines that
market risks or credit risks associated with such investments would subject the
Fund's portfolio to undue risk. The potential for realization of capital gains
resulting from possible changes in interest rates will not be a major
consideration. Other than for tax purposes, frequency of portfolio turnover
generally will not be a limiting factor if the Fund considers it advantageous to
purchase or sell securities. The Fund anticipates that its annual portfolio
turnover rate normally will be less than 200%. A high rate of portfolio turnover
involves correspondingly greater brokerage commission expenses or dealer costs
than a lower rate, which expenses and costs must be borne by the Fund and its
shareholders. High portfolio turnover may also result in the realization of
substantial net short-term capital gains and any distributions resulting from
such gains will be taxable. See "Tax Status" in this Prospectus and "Investment
Policies and Restrictions" in the Statement of Additional Information.
 
  TEMPORARY DEFENSIVE STRATEGIES. At times, conditions in the markets for
Florida insured municipal securities may, in the Adviser's judgment, make
pursuing the Fund's basic investment strategy inconsistent with the best
interests of its shareholders. At such times, the Adviser may use alternative
strategies primarily designed to reduce fluctuations in the value of the Fund's
assets. In implementing these "defensive" strategies, the Fund may invest to a
substantial degree in high-quality, short-term Florida municipal obligations. If
such municipal obligations are not available or, in the Adviser's judgment, do
not afford sufficient protection against adverse market conditions, the Fund may
invest in high-quality, municipal securities of issuers other than issuers of
Florida municipal securities. Furthermore, if such high-quality securities are
not available or, in the Adviser's judgment, do not afford sufficient protection
against adverse market conditions, the Fund may invest in taxable obligations.
Such taxable obligations may include: obligations of the U.S. Government, its
agencies or instrumentalities; other debt securities rated within the four
highest categories by either S&P or Moody's (or comparably rated by another
NRSRO); commercial paper rated in the highest grade by either rating service (or
comparably rated by another NRSRO); certificates of deposit and bankers'
acceptances; repurchase agreements with respect to any of the foregoing
investments; or any other fixed-income securities that the Adviser considers
consistent with such strategy. To the extent that the Fund invests a substantial
portion of its assets in
 
                                       10
<PAGE>   259
 
municipal securities other than Florida municipal securities or taxable
securities for temporary defensive purposes, the Fund will not be invested in a
manner primarily designed to achieve a high level of current income exempt from
federal income tax and Florida intangible personal property taxes. The Fund may
invest in insured and uninsured securities for temporary defensive purposes.

MUNICIPAL SECURITIES
- ------------------------------------------------------------------------------
 
  GENERAL. Municipal securities are obligations issued by or on behalf of
states, territories or possessions of the United States, the District of
Columbia and their political subdivisions, agencies and instrumentalities, the
interest on which, in the opinion of bond counsel or other counsel to the issuer
of such securities is, at the time of issuance, exempt from federal income tax.
Florida municipal securities are municipal securities the interest on which, in
the opinion of bond counsel or other counsel to the issuers of such securities,
is at the time of issuance exempt from Florida intangible personal property
taxes. Under normal market conditions, at least 80% of the Fund's assets will be
invested in Florida municipal securities. The policy stated in the foregoing
sentence is a fundamental policy of the Fund and cannot be changed without
approval of the shareholders of the Fund. Up to 20% of the Fund's assets may be
invested in securities that are subject to federal alternative minimum tax.
 
  The two principal classifications of municipal securities are "general
obligation" and "revenue" securities. "General obligation" securities are
secured by the issuer's pledge of its faith, credit and taxing power for the
payment of principal and interest. "Revenue" securities are usually payable only
from the revenues derived from a particular facility or class of facilities or,
in some cases, from the proceeds of a special excise tax or other specific
revenue source. Industrial development bonds are usually revenue securities, the
credit quality of which is normally directly related to the credit standing of
the industrial user involved.
 
  Within these principal classifications of municipal securities, there are a
variety of types of municipal securities, including fixed and variable rate
securities, municipal notes, municipal leases, custodial receipts, participation
certificates and derivative municipal securities the terms of which include
elements of, or are similar in effect to, certain Strategic Transactions (as
defined below) in which the Fund may engage. Variable rate securities bear rates
of interest that are adjusted periodically according to formulae intended to
reflect market rates of interest. The Fund may also invest in derivative
variable rate securities such as inverse floaters, whose rates vary inversely
with changes in market rates of interest. When market rates of interest
decrease, the change in value of such securities will have a positive effect on
the net asset value of the Fund and when market rates of interest increase, the
change in value of such securities will have a negative effect on the net asset
value of the Fund. The extent of increases and decreases in the value of inverse
floaters and the corresponding change to the net asset value of the Fund
generally
 
                                       11
<PAGE>   260
 
will be larger than comparable changes in the value of an equal principal amount
of a fixed rate municipal security having similar credit quality, redemption
provisions and maturity. The Fund will not invest more than 20% of its total
assets in securities whose rates vary inversely with changes in market rates of
interest.
 
  Municipal notes include tax, revenue and bond anticipation notes of short
maturity, generally less than three years, which are issued to obtain temporary
funds for various public purposes. Municipal leases are obligations issued by
state and local governments or authorities to finance the acquisition of
equipment and facilities. Certain municipal lease obligations may include
"non-appropriation" clauses which provide that the municipality has no
obligation to make lease or installment purchase payments in future years unless
money is appropriated for such purpose on a yearly basis. Custodial receipts are
underwritten by securities dealers or banks and evidence ownership of future
interest payments, principal payments or both on certain municipal securities.
Participation certificates are obligations issued by state or local governments
or authorities to finance the acquisition of equipment and facilities. They may
represent participations in a lease, an installment purchase contract, or a
conditional sales contract. Municipal securities may not be backed by the faith,
credit and taxing power of the issuer. Other than as set forth above, there is
no limitation with respect to the amount of the Fund's assets that may be
invested in the foregoing types of municipal securities. Certain of the
municipal securities in which the Fund may invest represent relatively recent
innovations in the municipal securities markets and the markets for such
securities may be less developed than the market for conventional fixed rate
municipal securities. A more detailed description of the types of municipal
securities in which the Fund may invest is included in the Statement of
Additional Information.
 
  Under normal market conditions, longer term municipal securities generally
provide a higher yield than shorter term municipal securities, and therefore the
Fund generally expects to invest primarily in longer term municipal securities.
The Fund will, however, invest in shorter term municipal securities when it
believes market conditions warrant such investments. The net asset value of the
Fund will change with changes in the value of its portfolio securities. Because
the Fund will invest primarily in fixed income municipal securities, the net
asset value of the Fund can be expected to change as general levels of interest
rates fluctuate. When interest rates decline, the value of a portfolio invested
in fixed income securities generally can be expected to rise. Conversely, when
interest rates rise, the value of a portfolio invested in fixed income
securities generally can be expected to decline. The prices of longer term
municipal securities generally are more volatile with respect to changes in
interest rates than the prices of shorter term municipal securities. Volatility
may be greater during periods of general economic uncertainty.
 
  Up to 20% of the Fund's assets may be invested in municipal securities that
are subject to federal alternative minimum tax. The Fund may not be a suitable
investment for investors who are already subject to the federal alternative
minimum
 
                                       12
<PAGE>   261
 
tax or who would become subject to the federal alternative minimum tax as a
result of an investment in the Fund. In addition, income earned or deemed to be
earned with respect to the Fund's Strategic Transactions, if any, will be
taxable. See "Tax Status."
 
  From time to time, proposals have been introduced before Congress that would
have the effect of reducing or eliminating the federal tax exemption on
municipal securities. If such a proposal were enacted, the ability of the Fund
to pay tax exempt interest dividends might be adversely affected.
 
  INSURED MUNICIPAL SECURITIES. Insured Florida municipal securities in which
the Fund may invest will be covered by Original Issue Insurance, Secondary
Market Insurance or Portfolio Insurance. Original Issue Insurance is purchased
with respect to a particular issue of municipal securities by the issuer thereof
or a third party in conjunction with the original issue of such municipal
securities. Secondary Market Insurance is purchased by the Fund or a third party
subsequent to the time of original issuance of a municipal security. Both
Original Issue Insurance and Secondary Market Insurance remain in effect as long
as the municipal securities covered thereby remain outstanding and the insurer
remains in business, regardless of whether the Fund ultimately disposes of such
municipal securities. Portfolio Insurance may be purchased by the Fund with
respect to municipal securities which the Fund intends to purchase or already
owns and would generally terminate when the municipal security is sold by the
Fund or redeemed. There is no limitation on the percentage of the Fund's assets
that may be invested in Florida municipal securities insured by any given
insurer.
 
  Original Issue Insurance, Secondary Market Insurance and Portfolio Insurance
generally do not insure payment on an accelerated basis, the payment of any
redemption premium (except with respect to certain premium payments in the case
of certain small issue industrial development and pollution control municipal
securities), the value of the Fund's shares or the market value of the Fund's
portfolio securities. Such insurance also does not insure against nonpayment of
principal of or interest on municipal securities resulting from the insolvency,
negligence or any other act or omission of the trustee or other paying agent for
such obligations.
 
  The Fund's policy of investing in Florida municipal securities insured by
insurers whose claims-paying ability is rated Aaa by Moody's, AAA by S&P or the
equivalent by another NRSRO will apply only at the time of the Fund's investment
in a Florida municipal security. A subsequent downgrade by Moody's, S&P or
another NRSRO of an insurer's claims-paying ability would result in a downgrade
of the rating assigned to the Florida municipal securities insured by such
insurer, although the Florida municipal securities may have an independent
rating that is higher than the new rating assigned to the insurer's
claims-paying ability. The securities could experience a decrease in market
price as a result of such a downgrade. In the event the ratings assigned to such
municipal securities decline to below investment grade, such municipal
securities would probably become less
 
                                       13
<PAGE>   262
 
liquid or even illiquid. There can be no assurance that an insurer will be able
to honor its obligations with respect to Florida municipal securities in the
Fund's portfolio. For a description of S&P's and Moody's claims-paying ability
ratings of insurers, see the Statement of Additional Information.
 
- ------------------------------------------------------------------------------
INVESTMENT PRACTICES
- ------------------------------------------------------------------------------
 
  In connection with the investment policies described above, the Fund also may
engage in strategic transactions and purchase and sell securities on a "when
issued" and "delayed delivery" basis. These investments entail risks. Strategic
transactions generally will not be treated as investments in tax-exempt
municipal securities for purposes of the Fund's 80% investment policy with
respect thereto.
 
  STRATEGIC TRANSACTIONS. The Fund may purchase and sell derivative instruments
such as exchange-listed and over-the-counter put and call options on securities,
financial futures, fixed-income indices and other financial instruments,
purchase and sell financial futures contracts and enter into various interest
rate transactions such as swaps, caps, floors or collars. Collectively, all of
the above are referred to as "Strategic Transactions." Strategic Transactions
may be used to attempt to protect against possible changes in the market value
of securities held in or to be purchased for the Fund's portfolio resulting from
securities markets, to protect the Fund's unrealized gains in the value of its
portfolio securities, to facilitate the sale of such securities for investment
purposes, to manage the effective maturity or duration of the Fund's portfolio,
or to establish a position in the derivatives markets as a temporary substitute
for purchasing or selling particular securities. Any or all of these investment
techniques may be used at any time and there is no particular strategy that
dictates the use of one technique rather than another, as use of any Strategic
Transaction is a function of numerous variables including market conditions. The
ability of the Fund to utilize these Strategic Transactions successfully will
depend on the Adviser's ability to predict pertinent market movements, which
cannot be assured. The Fund will comply with applicable regulatory requirements
when implementing these strategies, techniques and instruments.
 
  Strategic Transactions have risks associated with them including possible
default by the other party to the transaction, illiquidity and, to the extent
the Adviser's view as to certain market movements is incorrect, the risk that
the use of such Strategic Transactions could result in losses greater than if
they had not been used. Use of put and call options may result in losses to the
Fund, force the sale of portfolio securities at inopportune times or for prices
other than at current market values, limit the amount of appreciation the Fund
can realize on its investments or cause the Fund to hold a security it might
otherwise sell. The use of options and futures transactions entails certain
other risks. In particular, the variable degree of correlation between price
movements of futures contracts and price movements in the related portfolio
position of the Fund creates the possibility that losses on the hedging
instrument may be greater than gains in the value of the Fund's position. In
 
                                       14
<PAGE>   263
 
addition, futures and options markets may not be liquid in all circumstances and
certain over-the-counter options may have no markets. As a result, in certain
markets, the Fund might not be able to close out a transaction without incurring
substantial losses, if at all. Although the contemplated use of these futures
contracts and options thereon should tend to minimize the risk of loss due to a
decline in the value of the hedged position, at the same time they tend to limit
any potential gain which might result from an increase in value of such
position. Finally, the daily variation margin requirements for futures contracts
would create a greater ongoing potential financial risk than would purchases of
options, where the exposure is limited to the cost of the initial premium.
Losses resulting from the use of Strategic Transactions would reduce net asset
value, and possibly income, and such losses can be greater than if the Strategic
Transactions had not been utilized. The Strategic Transactions that the Fund may
use and some of their risks are described more fully in the Fund's Statement of
Additional Information.
 
  Income earned or deemed to be earned by the Fund from, among other things, its
Strategic Transactions and temporary defensive strategies, if any, generally
will be taxable income of the Fund. See "Tax Status."
 
   
  "WHEN ISSUED" AND "DELAYED DELIVERY" TRANSACTIONS. The Fund may also purchase
and sell municipal securities on a "when issued" and "delayed delivery" basis.
No income accrues to the Fund on municipal securities in connection with such
purchase transactions prior to the date the Fund actually takes delivery of such
securities. These transactions are subject to market fluctuation; the value of
the municipal securities at delivery may be more or less than their purchase
price, and yields generally available on municipal securities when delivery
occurs may be higher or lower than yields on the municipal securities obtained
pursuant to such transactions. Because the Fund relies on the buyer or seller,
as the case may be, to consummate the transaction, failure by the other party to
complete the transaction may result in the Fund missing the opportunity of
obtaining a price or yield considered to be advantageous. When the Fund is the
buyer in such a transaction, however, it will maintain, in a segregated account
with its custodian, cash or liquid securities having an aggregate value equal to
the amount of such purchase commitments until payment is made. The Fund will
make commitments to purchase municipal securities on such basis only with the
intention of actually acquiring these securities, but the Fund may sell such
securities prior to the settlement date if such sale is considered to be
advisable. To the extent the Fund engages in "when issued" and "delayed
delivery" transactions, it will do so for the purpose of acquiring securities
for the Fund's portfolio consistent with the Fund's investment objectives and
policies and not for the purposes of investment leverage. No specific limitation
exists as to the percentage of the Fund's assets which may be used to acquire
securities on a "when issued" or "delayed delivery" basis.
    
 
  RESTRICTED AND ILLIQUID SECURITIES. The Fund may invest up to 15% of its net
assets in illiquid securities including securities the disposition of which is
subject to
 
                                       15
<PAGE>   264
 
substantial legal or contractual restrictions on resale and securities that are
not readily marketable. The sale of restricted and illiquid securities often
requires more time and results in higher brokerage charges or dealer discounts
and other selling expenses than does the sale of securities eligible for trading
on national securities exchanges or in the over-the-counter markets. Restricted
securities may sell at a price lower than similar securities that are not
subject to restrictions on resale.
 
  OTHER PRACTICES. The Fund may borrow amounts up to 5% of its net assets in
order to pay for redemptions when liquidation of portfolio securities is
considered disadvantageous or inconvenient and may pledge up to 10% of its net
assets to secure such borrowings.
 
  Under normal market conditions, the Fund will invest substantially all of its
assets in insured Florida municipal securities. The Fund generally will not
invest more than 25% of its total assets in any industry. Governmental issuers
of municipal securities are not considered part of any "industry." However,
municipal securities backed only by the assets and revenues of nongovernmental
users may for this purpose be deemed to be issued by such nongovernmental users,
and the 25% limitation would apply to such obligations. It is therefore possible
that the Fund may invest more than 25% of its assets in a broader segment of the
municipal securities market, such as revenue obligations of hospitals and other
health care facilities, housing agency revenue obligations, or airport revenue
obligations if the Adviser determines that the yields available from obligations
in a particular segment of the market justifies the additional risks associated
with a large investment in such segment. Although such obligations could be
supported by the credit of governmental users, or by the credit of
nongovernmental users engaged in a number of industries, economic, business,
political and other developments generally affecting the revenues of such users
(for example, proposed legislation or pending court decisions affecting the
financing of such projects and market factors affecting the demand for their
services or products) may have a general adverse effect on all municipal
securities in such a market segment.
 
  From time to time, the Fund's investments may include securities as to which
the Fund, by itself or together with other funds or accounts managed by the
Adviser, holds a major portion or all of an issue of Florida municipal
securities. Because there may be relatively few potential purchasers for such
investments and, in some cases, there may be contractual restrictions on
resales, the Fund may find it more difficult to sell such securities at a time
when the Adviser believes it is advisable to do so.
 
  INVESTMENT RESTRICTIONS. The Fund is subject to certain investment
restrictions which constitute fundamental policies. Fundamental policies cannot
be changed without the approval of the holders of a majority of the Fund's
outstanding voting securities, as defined in the 1940 Act. See "Investment
Policies and Restrictions" in the Statement of Additional Information.
 
                                       16
<PAGE>   265
 
  PORTFOLIO TRANSACTIONS AND BROKERAGE ALLOCATION. 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 prices and any
brokerage commissions. The income securities in which the Fund invests are
traded principally in the over-the-counter market. In the over-the-counter
market, securities are generally traded on a net basis with dealers acting as
principal for their own accounts without a stated commission, although the price
of the security usually includes a mark-up to the dealer. Securities purchased
in underwritten offerings generally include, in the price, a fixed amount of
compensation for the managers, underwriters and dealers. The Fund may also
purchase certain money market instruments directly from an issuer, in which case
no commissions or discounts are paid. Purchases and sales of bonds on a stock
exchange are effected through brokers who charge a commission for their
services.
 
  The Adviser is responsible for effecting securities transactions of the Fund
and will do so in a manner deemed fair and reasonable to shareholders of the
Fund and not according to any formula. The Adviser's primary considerations in
selecting the manner of executing securities transactions for the Fund will be
prompt execution of orders, the size and breadth of the market for the security,
the reliability, integrity and financial condition and execution capability of
the firm, the size of and difficulty in executing the order, and the best net
price. There are many instances when, in the judgment of the Adviser, more than
one firm can offer comparable execution services. In selecting among such firms,
consideration is given to those firms which supply research and other services
in addition to execution services. However, it is not the policy of the Adviser,
absent special circumstances, to pay higher commissions to a firm because it has
supplied such services.
 
  In effecting purchases and sales of the Fund's portfolio securities, the
Adviser and the Fund may place orders with and pay brokerage commissions to
brokers, including brokers which may be affiliated with the Fund, the Adviser
and the Distributor or dealers participating in the offering of the Fund's
shares. In addition, in selecting among firms to handle a particular
transaction, the Adviser and the Fund may take into account whether the firm has
sold or is selling shares of the Fund. See "Portfolio Transactions and Brokerage
Allocation" in the Statement of Additional Information for more information.
 
- ------------------------------------------------------------------------------
SPECIAL CONSIDERATIONS REGARDING THE FUND
- ------------------------------------------------------------------------------
 
  GENERAL. The Fund may invest up to 20% of its total assets in derivative
variable rate securities such as inverse floaters whose rates of interest vary
inversely with changes in market rates of interest. When market rates of
interest decrease, the change in value of such securities will have a positive
effect on the net asset value of the Fund and when market rates of interest
increase, the change in value of such securities will have a negative effect on
the net asset value of the Fund. Investment in such securities involve special
risks as compared to a fixed rate municipal
 
                                       17
<PAGE>   266
 
security. The extent of increases and decreases in the value of inverse floaters
and the corresponding change to per share net asset value of the Fund generally
will be larger than comparable changes in the value of an equal principal amount
of a fixed rate municipal security having similar credit quality, redemption
provisions and maturity. The markets for inverse variable rate securities may be
less developed than the market for conventional fixed rate municipal securities.
 
  SPECIAL CONSIDERATIONS REGARDING FLORIDA MUNICIPAL SECURITIES. As described in
this Prospectus, under normal market conditions the Fund will invest
substantially all of its assets in Florida municipal securities. The Fund is
therefore susceptible to political, economic, regulatory or other factors
affecting issuers of Florida municipal securities. Investors should be aware of
certain factors that might affect the financial condition of the issuers of
Florida municipal securities.
 
  The following information is a summary of a more detailed description of
certain factors affecting Florida municipal securities which is contained in the
Statement of Additional Information. Investors should obtain a copy of the
Statement of Additional Information for the more detailed discussion of such
factors. Such information is derived from certain official statements of the
State of Florida published in connection with the issuance of specific Florida
municipal securities, as well as from other publicly available documents. Such
information has not been independently verified by the Fund and may not apply to
all Florida municipal securities acquired by the Fund. The Fund assumes no
responsibility for the completeness or accuracy of such information.
 
  Florida state and local government obligations may be adversely affected by
political and economic conditions and developments within the State of Florida
and the nation as a whole.
 
   
  Florida's economic outlook is projected generally to reflect the national
economic outlook and is expected to experience steady if unspectacular growth
over the next couple of years. Historically, Florida's unemployment rate has
generally tracked below that of the nation; however, in recent years, as the
State's economic growth has slowed from its previous highs, the unemployment
rate has tracked above the national average. The average rate of unemployment
for Florida since 1986 is 6.2% while the national average during the same time
period is also 6.2%. Florida's unemployment rate is forecasted at 5.3% for
fiscal year 1996-97 and fiscal year 1997-98.
    
 
   
  For the State fiscal year which ended June 30, 1996, receipts from the sales
and use tax, the greatest single source of tax revenue to the State of Florida,
were $11,461 million, an increase of 7.4% from fiscal year 1994-95.
    
 
   
  Tourism is one of Florida's most important industries. Approximately 40.7
million people visited the State in 1995. Tourist arrivals are expected to
increase 2.7% this fiscal year and 3.2% next fiscal year. By the end of fiscal
year 1996-97 42.6 million domestic and international tourists are expected to
have visited the state. In 1997-98, tourist arrivals should approximate 43.9
million.
    
 
                                       18
<PAGE>   267
 
  County and municipal governments in Florida depend primarily upon ad valorem
property taxes, sales, motor fuel and other local excise taxes and miscellaneous
revenue sources, including revenues from utilities services. Florida school
districts derive substantially all of their revenues from local property taxes.
The overall level of revenue from these sources is in part dependent upon the
local, state and national economies. Local government obligations held by the
Fund may constitute general obligations or may be special obligations payable
solely from one or more specified revenue sources. The ability of the local
governments to repay their obligations on a timely basis will be dependent upon
the continued strength of the revenues pledged and of the overall fiscal status
of the local government.
 
   
  Voters at the general election in November 1994 approved an amendment to the
Constitution of the State of Florida limiting future state revenues. It is
unclear what effect, if any, such amendment would have on state or local
government debt obligations.
    
 
  The value of Florida municipal instruments may also be affected by general
conditions in the money markets or the municipal bond markets, the levels of
federal income tax rates, the supply of tax-exempt bonds, the credit quality and
rating of the issues and perceptions with respect to the level of interest
rates.
 
  There can be no assurance that there will not be a decline in economic
conditions or that particular Florida municipal securities in the portfolio of
the Fund will not be adversely affected by any such changes.
 
  More detailed information concerning Florida municipal securities and the
State of Florida is included in the Statement of Additional Information.

  PERSONAL INVESTING POLICIES. The Fund and the Adviser have adopted Codes of
Ethics designed to recognize the fiduciary relationship between the Fund and the
Adviser and its employees. The Codes permit directors, trustees, officers and

certain restrictions. Persons with access to certain sensitive information are
subject to preclearance and other procedures designed to prevent conflicts of
interest.
    
 
  PORTFOLIO MANAGEMENT. David C. Johnson, a Senior Vice President of the
Adviser, supervises the Adviser's municipal securities practice area and
coordinates the Adviser's investment policy regarding such securities. Mr.
Johnson has been employed by the Adviser since April 1989. Mr. Piraro, a Vice
President of the Adviser, has been primarily responsible for the day-to-day
management of the Fund's portfolio since August 1995. Mr. Piraro has been
employed by the Adviser since May 1992. Prior to May 1992, Mr. Piraro was

- ------------------------------------------------------------------------------
ALTERNATIVE SALES ARRANGEMENTS
- ------------------------------------------------------------------------------
 
  The Alternative Sales Arrangements permit an investor to choose the method of
purchasing shares that is more beneficial to the investor, taking into account
the amount of the purchase, the length of time the investor expects to hold the
shares, whether the investor wishes to receive dividends in cash or to reinvest
them in additional shares of the Fund, and other circumstances. Investors should
consider such factors together with the amount of sales charges and accumulated
distribution and service fees with respect to each class of shares that may be
incurred over the anticipated duration of their investment in the Fund.
 
  The Fund offers three classes of shares, designated Class A Shares, Class B
Shares and Class C Shares. Shares of each class are offered at a price equal to
their net asset value per share plus a sales charge which, at the election of
the purchaser, may be imposed (a) at the time of purchase ("Class A Shares") or
(b) on a contingent deferred basis (Class A Share accounts over $1 million,
"Class B Shares" and "Class C Shares"). Class A Shares accounts over $1 million
or otherwise subject to a contingent deferred sales charge ("CDSC"), Class B
Shares and Class C Shares sometimes are referred to herein collectively as
"Contingent Deferred Sales Charge Shares" or "CDSC Shares."
 
  The minimum initial investment with respect to each class of shares is $500.
The minimum subsequent investment with respect to each class of shares is $25.
It is presently the policy of the Distributor not to accept any order for Class
B
 
                                       21
<PAGE>   270
 
Shares in an amount of $500,000 or more and not to accept any order for Class C
Shares in an amount of $1 million or more because it ordinarily will be more
advantageous for an investor making such an investment to purchase Class A
Shares.
 
  An investor should carefully consider the sales charges applicable to each
class of shares and the estimated period of their investment to determine which
class of shares is more beneficial for the investor to purchase. For example,
investors who would qualify for a significant purchase price discount from the
maximum sales charge on Class A Shares may determine that payment of such a
reduced front-end sales charge is superior to electing to purchase Class B
Shares or Class C Shares, each with no front-end sales charge but subject to a
CDSC and a higher aggregate distribution and service fee. However, because
initial sales charges are deducted at the time of purchase of Class A Share
accounts under $1 million, a purchaser of such Class A Shares would not have all
of his or her funds invested initially and therefore, would initially own fewer
shares than if Class B Shares or Class C Shares had been purchased. On the other
hand, an investor whose purchase would not qualify for price discounts
applicable to Class A Shares and intends to remain invested until after the
expiration of the applicable CDSC may wish to defer the sales charge and have
all his or her funds initially invested in Class B Shares or Class C Shares. If
such an investor anticipates that he or she will redeem such shares prior to the
expiration of the CDSC period applicable to Class B Shares, the investor may
wish to acquire Class C Shares. Investors must weigh the benefit of deferring
the sales charge and having all of their funds invested against the higher
aggregate distribution and service fee applicable to Class B Shares and Class C
Shares (discussed below).
 
  Each class of shares represents an interest in the same portfolio of
investments of the Fund and has the same rights, except each class of shares (i)
bears those distribution fees, service fees and administrative expenses
applicable to the respective class of shares as a result of its sales
arrangements, (ii) has exclusive voting rights with respect to those provisions
of the Fund's Rule 12b-1 distribution plan which relate only to such class and
(iii) has a different exchange privilege. Generally, a class of shares subject
to a higher ongoing distribution and service fee or subject to the conversion
feature will have a higher expense ratio and pay lower dividends than a class of
shares subject to a lower ongoing distribution and service fee or not subject to
the conversion feature. The per share net asset values of the different classes
of shares are expected to be substantially the same; from time to time, however,
the per share net asset values of the classes may differ. The net asset value
per share of each class of shares of the Fund will be determined as described in
this Prospectus under "Purchase of Shares -- Net Asset Value."
 
   
  The administrative expenses that may be allocated to a specific class of
shares may consist of (i) ACCESS' expenses attributable to a specific class of
shares, which expenses typically will be higher with respect to classes of
shares subject to the conversion feature; (ii) printing and postage expenses
related to preparing and
    
 
                                       22
<PAGE>   271
 
distributing materials such as shareholder reports, prospectuses and proxy
statements to current shareholders of a specific class; (iii) Securities and
Exchange Commission (the"SEC") registration fees incurred by a class of shares;
(iv) the expense of administrative personnel and services as required to support
the shareholders of a specific class; (v) Trustees' fees or expense incurred as
a result of issues relating to one class of shares; (vi) accounting expenses
relating solely to one class of shares; and (vii) any other incremental expenses
subsequently identified that should be properly allocated to one or more classes
of shares. All such expenses incurred by a class will be borne on a pro rata
basis by the outstanding shares of such class. All allocations of administrative
expenses to a particular class of shares will be limited to the extent necessary
to preserve the Fund's qualification as a regulated investment company under the
Internal Revenue Code of 1986, as amended (the "Code").
 
- ------------------------------------------------------------------------------
PURCHASE OF SHARES
- ------------------------------------------------------------------------------
 
   
  The Fund offers three classes of shares to the public on a continuous basis
through the Distributor, as principal underwriter, which is located at One
Parkview Plaza, Oakbrook Terrace, Illinois 60181. Shares also are offered
through members of the National Association of Securities Dealers, Inc. ("NASD")
acting as securities dealers ("dealers") and through NASD members acting as
brokers for investors ("brokers") or eligible non-NASD members acting as agents
for investors ("financial intermediaries"). The Fund reserves the right to
suspend or terminate the continuous public offering of its shares at any time
and without prior notice.
    
 
  The Fund's shares are offered at the net asset value per share next computed
after an investor places an order to purchase directly with the investor's
broker, dealer or financial intermediary or directly with the Distributor plus
any applicable sales charge. Sales personnel or brokers, dealers and financial
intermediaries distributing the Fund's shares may receive different compensation
for selling different classes of shares. It is the responsibility of the
investor's broker, dealer or financial intermediary to transmit the order to the
Distributor. Because the Fund generally will determine net asset value once each
business day as of the close of business, purchase orders placed through an
investor's broker, dealer or financial intermediary must be transmitted to the
Distributor by such broker, dealer or financial intermediary prior to such time
in order for the investor's order to be fulfilled on the basis of the net asset
value to be determined that day. Any change in the purchase price due to the
failure of the Distributor to receive a purchase order prior to such time must
be settled between the investor and the broker, dealer or financial intermediary
submitting the order.
 
  The Distributor may from time to time implement programs under which a broker,
dealer or financial intermediary's sales force may be eligible to win nominal
awards for certain sales efforts or under which the Distributor will reallow to
any broker, dealer or financial intermediary that sponsors sales contests or
recognition
 
                                       23
<PAGE>   272
 
   
programs conforming to criteria established by the Distributor, or participates
in sales programs sponsored by the Distributor, an amount not exceeding the
total applicable sales charges on the sales generated by the broker, dealer or
financial intermediary at the public offering price during such programs. Other
programs provide, among other things and subject to certain conditions, for
certain favorable distribution arrangements for shares of the Fund. Also, the
Distributor in its discretion may from time to time, pursuant to objective
criteria established by it, pay fees to, and sponsor business seminars for,
qualifying brokers, dealers or financial intermediaries for certain services or
activities which are primarily intended to result in sales of shares of the
Fund. Fees may include payment for travel expenses, including lodging, incurred
in connection with trips taken by invited registered representatives and members
of their families to locations within or outside of the United States for
meetings or seminars of a business nature. In some instances additional
compensation or promotional incentives may be offered to brokers, dealers or
financial intermediaries that have sold or may sell significant amounts of
shares during specified periods of time. The Distributor may provide additional
compensation to Edward D. Jones & Co. or an affiliate thereof based on a
combination of its sales of shares and increases in assets under management.
Such payments to brokers, dealers and financial intermediaries for sales
contests, other sales programs and seminars are made by the Distributor out of
its own assets and not out of the assets of the Fund. Such fees paid for such
services and activities with respect to the Fund will not exceed in the
aggregate 1.25% of the average total daily net assets of the Fund on an annual
basis. These programs will not change the price an investor pays for shares or
the amount that the Fund will receive from such sale.
    
 
CLASS A SHARES
 
  The public offering price of Class A Shares is equal to the net asset value
per share plus an initial sales charge which is a variable percentage of the
offering price depending upon the amount of the sale. The table below shows
total sales charges and dealer concessions reallowed to dealers and agency
commissions paid to brokers with respect to sales of Class A Shares. The sales
charge is allocated between the investor's broker, dealer or financial
intermediary and the Distributor. As indicated previously, at the discretion of
the Distributor the entire sales charge may be reallowed to such broker, dealer
or financial intermediary. The staff of the SEC has taken the position that
dealers who receive 90% or more of the sales charge may be deemed to be
"underwriters" as that term is defined in the Securities Act of 1933, as
amended.

* No sales charge is payable at the time of purchase on investments of $1
  million or more, although for such investments the Fund imposes a CDSC of
  1.00% on redemptions made within one year of the purchase. A commission
  will be paid to brokers, dealers or financial intermediaries who initiate
  and are responsible for purchases of $1 million or more as follows: 1.00%
  on sales to $2 million, plus 0.80% on the next $1 million and 0.50% on the
  excess over $3 million. See "Purchase of Shares--Deferred Sales Charge
  Alternatives" for additional information with respect to CDSCs.
    
 
QUANTITY DISCOUNTS
 
  Investors purchasing Class A Shares may, under certain circumstances, be
entitled to pay reduced sales charges. The circumstances under which such
investors may pay reduced sales charges are described below.
 
  Investors, or their brokers, dealers or financial intermediaries, must notify
the Fund whenever a quantity discount is applicable to purchases. Upon such
notification, an investor will receive the lowest applicable sales charge.
Quantity discounts may be modified or terminated at any time. For more
information about quantity discounts, investors should contact their broker,
dealer or financial intermediary or the Distributor.
 
   
  A person eligible for a reduced sales charge includes an individual, their
spouse and children under 21 years of age and any corporation, partnership or
sole proprietorship which is 100% owned, either alone or in combination, by any
of the foregoing; a trustee or other fiduciary of a single trust estate or a
single fiduciary account; or a "company" as defined is section 2(a)(8) of the
1940 Act.
    
 
   
  As used herein, "Participating Funds" refers to all open-end investment
companies advised by the Adviser or Van Kampen American Capital Asset
Management, Inc. and distributed by the Distributor. Additional funds may be
added from time to time as determined by the Fund's Board of Trustees as
Participating Funds.
    
 
   
  VOLUME DISCOUNTS. The size of investment shown in the preceding sales charge
table applies to the total dollar amount being invested by any person at any one
time
    
 
                                       25
<PAGE>   274
 
   
in Class A Shares of the Fund, or in any combination of shares of the Fund and
shares of other Participating Funds, although other Participating Funds may have
different sales charges.
    
 
   
  CUMULATIVE PURCHASE DISCOUNT. The size of investment shown in the preceding
sales charge table may also be determined by combining the amount being invested
in Class A Shares of the Fund with other shares of the Fund and shares of
Participating Funds, plus the current offering price of all shares of the Fund
and other Participating Funds which have been previously purchased and are still
owned.
    
 
   
  LETTER OF INTENT. A Letter of Intent provides an opportunity for an investor
to obtain a reduced sales charge by aggregating the amount being invested over a
13-month period to determine the sales charge as outlined in the preceding sales
charge table. The size of investment shown in the preceding table includes the
amount of intended purchases of Class A Shares of the Fund with other shares of
the Fund and shares of the Participating Funds plus the value of all shares of
the Fund and other Participating Funds previously purchased during such 13-month
period and still owned. An investor may elect to compute the 13-month period
starting up to 90 days before the date of execution of a Letter of Intent. Each
investment made during the period receives the reduced sales charge applicable
to the total amount of the investment goal. If trades not initially made under a
Letter of Intent subsequently qualify for a lower sales charge through the
90-day back-dating provision, an adjustment will be made at the expiration of
the Letter of Intent to give effect to the lower charge. If the goal is not
achieved within the 13-month period, the investor must pay the difference
between the sales charge applicable to the purchases made and the sales charges
previously paid. When an investor signs a Letter of Intent, shares equal to at
least 5% of the total purchase amount of the level selected will be restricted
from sale or redemption by the investor until the Letter of Intent is satisfied
or any additional sales charges have been paid; if the Letter of Intent is not
satisfied by the investor and any additional sales charges are not paid,
sufficient restricted shares will be redeemed by the Fund to pay such charges.
Additional information is contained in the application accompanying this
Prospectus.
    
 
OTHER PURCHASE PROGRAMS
 
   
  Purchasers of Class A Shares may be entitled to reduced initial sales charges
in connection with unit investment trust reinvestment programs and purchases by
registered representatives of selling firms or purchases by persons affiliated
with the Fund or the Distributor. The Fund reserves the right to modify or
terminate these arrangements at any time.
    
 
  UNIT INVESTMENT TRUST REINVESTMENT PROGRAMS. The Fund permits unitholders of
unit investment trusts to reinvest distributions from such trusts in Class A
Shares of the Fund at net asset value with no minimum initial or subsequent
investment requirement if the administrator of an investor's unit investment
trust program
 
                                       26
<PAGE>   275
 
meets certain uniform criteria relating to cost savings by the Fund and the
Distributor. The total sales charge for all other investments made from unit
trust distributions will be 1.00% of the offering price (1.01% of net asset
value). Of this amount, the Distributor will pay to the broker, dealer or
financial intermediary, if any, through which such participation in the
qualifying program was initiated 0.50% of the offering price as a dealer
concession or agency commission. Persons desiring more information with respect
to this program, including the applicable terms and conditions thereof, should
contact their broker, dealer, financial intermediary or the Distributor.
 
   
  The administrator of such a unit investment trust must have an agreement with
the Distributor pursuant to which the administrator will (1) submit a single
bulk order and make payment with a single remittance for all investments in the
Fund during each distribution period by all investors who choose to invest in
the Fund through the program and (2) provide ACCESS with appropriate backup data
for each participating investor in a computerized format fully compatible with
ACCESS' processing system.
    
 
   
  As further requirements for obtaining these special benefits, the Fund also
requires that all dividends and other distributions by the Fund be reinvested in
additional shares without any systematic withdrawal program. There will be no
minimum for reinvestments from unit investment trusts. The Fund will send
account activity statements to such participants on a monthly basis only, even
if their investments are made more frequently. The Fund reserves the right to
modify or terminate this program at any time.
    
 
  NAV PURCHASE OPTIONS. Class A Shares of the Fund may be purchased at net asset
value, upon written assurance that the purchase is made for investment purposes
and that the shares will not be resold except through redemption by the Fund,
by:
 
   
  (1) Current or retired trustees or directors of funds advised by the Adviser
      or Van Kampen American Capital Asset Management, Inc. and such persons'
      families and their beneficial accounts.
    
 
   
  (2) Current or retired directors, officers and employees of Morgan Stanley
      Group Inc. and any of its subsidiaries, employees of an investment
      subadviser to any fund described in (1) above or an affiliate of such
      subadviser; and such persons' families and their beneficial accounts.
    
 
   
  (3) Directors, officers, employees and registered representatives of financial
      institutions that have a selling group agreement with the Distributor and
      their spouses and children under 21 years of age when purchasing for any
      accounts they beneficially own, or, in the case of any such financial
      institution, when purchasing for retirement plans for such institution's
      employees.
    
 
                                       27
<PAGE>   276
 
   
  (4) Registered investment advisers, trust companies and bank trust departments
      investing on their own behalf or on behalf of their clients provided that
      the aggregate amount invested in Class A Shares of the Fund alone, or any
      combination of shares of the Fund and shares of other Participating Funds
      as described herein under "Purchase of Shares -- Class A Shares --
      Quantity Discounts," during the 13-month period commencing with the first
      investment pursuant hereto equals at least $1 million. The Distributor may
      pay brokers, dealers or financial intermediaries through which purchases
      are made an amount up to 0.50% of the amount invested, over a 12-month
      period following such transaction.
    
 
   
  (5) Trustees and other fiduciaries purchasing shares for retirement plans of
      organizations with retirement plan assets of $3 million or more and which
      invest in multiple fund families through national wirehouse alliance
      programs.
    
 
  (6) Accounts as to which a broker, dealer or financial intermediary charges an
      account management fee ("wrap accounts"), provided the broker, dealer or
      financial intermediary has a separate agreement with the Distributor.
 
  (7) Investors purchasing shares of the Fund with redemption proceeds from
      other mutual fund complexes on which the investor has paid a front-end
      sales charge or was subject to a deferred sales charge, whether or not
      paid, if such redemption has occurred no more than 30 days prior to such
      purchase.
 
   
  (8) Trusts created under pension, profit sharing or other employee benefit
      plans qualified under Section 401(a) of the Code, or custodial accounts
      held by a bank created pursuant to Section 403(b) of the Code and
      sponsored by non-profit organizations defined under Section 501(c)(3) of
      the Code and assets held by an employer or trustee in connection with an
      eligible deferred compensation plan under Section 457 of the Code. Such
      plans will qualify for purchases at net asset value provided, for plans
      initially establishing accounts with the Distributor in the Participating
      Funds after February 1, 1997, that (1) the initial amount invested in the
      Participating Funds is at least $500,000 or (2) such shares are purchased
      by an employer sponsored plan with more than 100 eligible employees. Such
      plans that have been established with a Participating Fund or have
      received proposals from the Distributor prior to February 1, 1997 based on
      net asset value purchase privileges previously in effect will be qualified
      to purchase shares of the Participating Funds at net asset value for
      accounts established on or before May 1, 1997. Section 403(b) and similar
      accounts for which Van Kampen American Capital Trust Company served as
      custodian will not be eligible for net asset value purchases based on the
      aggregate investment made by the plan or the number of eligible employees,
      except under certain uniform criteria established by the Distributor from
      time to time. Prior to February 1, 1997, a commission will be paid to
      authorized dealers who initiate and are responsible for such purchases
      within a rolling twelve-month period as
    
 
                                       28
<PAGE>   277
 
   
      follows: 1.00% on sales to $5 million, plus 0.50% on the next $5 million
      and 0.25% on the excess over $10 million. For purchases on February 1,
      1997 and thereafter, a commission will be paid as follows: 1.00% on sales
      to $2 million, plus 0.80% on the next $1 million, plus 0.50% on the next
      $47 million and 0.25% on the excess over $50 million.
    
 
   
  (9) Individuals who are members of a "qualified group". For this purpose, a
      qualified group is one which (i) has been in existence for more than six
      months, (ii) has a purpose other than to acquire shares of the fund or
      similar investments, (iii) has given and continues to give its endorsement
      or authorization, on behalf of the group, for purchase of shares of the
      fund and other Participating funds, (iv) has a membership that the
      authorized dealer can certify as to the group's members and (v) satisfies
      other uniform criteria established by the Distributor for the purpose of
      realizing economics of scale in distributing such shares. A qualified
      group does not include one whose sole organizational nexus, for example,
      is that its participants are credit card holders of the same institution,
      policy holders of an insurance company, customers of a bank or
      broker-dealer, clients of an investment adviser or other similar groups.
      Shares purchased in each group's participants account in connection with
      this privilege will be subject to a CDSC of 1.00% in the event of
      redemption within one year of purchase, and a commission will be paid to
      authorized dealers who initiate and are responsible for such sales to each
      individual as follows: 1.00% on sales to $2 million, plus 0.80% on the
      next $1 million and 0.50% on the excess over $3 million.
    
 
   
The term "families" includes a person's spouse, children under 21 years of age
and grandchildren, parents, and a person's spouse's parents.
    
 
   
  Purchase orders made pursuant to clause (4) may be placed either through
authorized brokers, dealers or financial intermediaries as described above or
directly with ACCESS, the investment adviser, trust company or bank trust
department, provided that ACCESS receives federal funds for the purchase by the
close of business on the next business day following acceptance of the order. An
authorized broker, dealer or financial intermediary may charge a transaction fee
for placing an order to purchase shares pursuant to this provision or for
placing a redemption order with respect to such shares. The Fund may terminate,
or amend the terms of, offering shares of the Fund at net asset value to such
groups at any time.
    
 
DEFERRED SALES CHARGE ALTERNATIVE
 
  Investors choosing the deferred sales charge alternative may purchase Class A
Shares in an amount of $1 million or more, Class B Shares or Class C Shares. The
public offering price of a CDSC Share is equal to the net asset value per share
without the imposition of a sales charge at the time of purchase. CDSC Shares
are sold without an initial sales charge so that the Fund may invest the full
amount of the investor's purchase payment. The Distributor will compensate
brokers, dealers and financial intermediaries participating in the continuous
public offering of the
 
                                       29
<PAGE>   278
 
   
CDSC Shares out of its own assets, and not out of assets of the Fund, as a
percentage rate of the dollar value of the CDSC Shares purchased from the Fund
by such brokers, dealers and financial intermediaries, which percentage rate
will be equal to (i) with respect to Class A Shares, 1.00% on sales to $2
million, plus 0.80% on the next $1 million and 0.50% on the excess over $3
million; (ii) 4.00% with respect to Class B Shares; and (iii) 1.00% with respect
to Class C Shares. Such compensation will not change the price an investor will
pay for CDSC Shares or the amount that the Fund will receive from such sale.
    
 
   
  CDSC Shares redeemed within a specified period of time generally will be
subject to a CDSC at the rates set forth below charged as a percentage of the
dollar amount subject thereto. The amount of the CDSC will vary depending on (i)
the class of CDSC Shares to which such shares belong and (ii) the number of
years from the time of payment for the purchase of the CDSC Shares until the
time of their redemption. The charge will be assessed on an amount equal to the
lesser of the then current market value or the original purchase price of the
CDSC Shares being redeemed. Accordingly, no sales charge will be imposed on
increases in net asset value above the initial purchase price. In addition, no
CDSC will be assessed on CDSC Shares derived from reinvestment of dividends or
capital gains distributions. Solely for purposes of determining the number of
years from the time of any payment for the purchases of CDSC Shares, all
payments during a month will be aggregated and deemed to have been made on the
last day of the month.
    
 
   
  Proceeds from the CDSC and the distribution fee applicable to a class of CDSC
Shares are paid to the Distributor and are used by the Distributor to defray its
expenses related to providing distribution related services to the Fund in
connection with the sale of shares of such class of CDSC Shares, such as the
payment of compensation to selected dealers and agents and for selling such
shares. The combination of the CDSC and the distribution fees facilitates the
ability of the Fund to sell such CDSC Shares without a sales charge being
deducted at the time of purchase.
    
 
   
  In determining whether a CDSC is applicable to a redemption of CDSC Shares, it
will be assumed that the redemption is made first of any CDSC Shares acquired
pursuant to reinvestment of dividends or distributions, second of CDSC Shares
that have been held for a sufficient period of time such that the CDSC no longer
is applicable to such shares, third of Class A Shares in the shareholder's Fund
account that have converted from Class B Shares or Class C Shares, if any, and
fourth of CDSC Shares held longest during the period of time that a CDSC is
applicable to such CDSC Shares. The charge will not be applied to dollar amounts
representing an increase in the net asset value since the time of purchase.
    
 
  To provide an example, assume an investor purchased 100 Class B Shares at $10
per share (at a cost of $1,000) and in the second year after purchase, the net
asset value per share is $12 and, during such time, the investor has acquired 10
additional Class B Shares upon dividend reinvestment. If at such time the
investor makes his first redemption of 50 shares (proceeds of $600), 10 shares
will not be subject to
 
                                       30
<PAGE>   279
 
charge because of dividend reinvestment. With respect to the remaining 40
shares, the charge is applied only to the original cost of $10 per share and not
to the increase in net asset value of $2 per share. Therefore, $400 of the $600
redemption proceeds will be charged at a rate of 3.75% (the applicable rate in
the second year after purchase).
 
   
  CLASS A SHARE PURCHASES OF $1 MILLION OR MORE. No sales charge is payable at
the time of purchase on investments in Class A Shares of $1 million or more,
although for such investments the Fund imposes a CDSC of 1.00% on redemptions
made within one year of the purchase. A commission will be paid to dealers who
initiate and are responsible for purchases of $1 million or more as follows:
1.00% on sales to $2 million, plus 0.80% on the next $1 million, and 0.50% on
the excess over $3 million.
    
 
   
  CLASS B SHARES. Class B Shares redeemed within seven years of purchase
generally will be subject to a CDSC at the rates set forth below, charged as a
percentage of the dollar amount subject thereto:

  The CDSC generally is waived on redemptions of Class B Shares made pursuant to
the Systematic Withdrawal Plan. See "Shareholder Services--Systematic Withdrawal
Plan."
    
 
   
  CLASS C SHARES. Class C Shares redeemed within the first 12 months of purchase
generally will be subject to a CDSC of 1.00% of the dollar amount subject
thereto. Class C Shares redeemed thereafter will not be subject to a CDSC.
    
 
   
  CONVERSION FEATURE. Class B Shares purchased on or after June 1, 1996 and any
dividend reinvestment plan shares received thereon automatically convert to
Class A Shares eight years after the end of the calendar month in which the
shares were purchased. Class B Shares purchased before June 1, 1996, and any
dividend reinvestment plan shares received thereon, automatically convert to
Class A shares seven years after the end of the calendar month in which the
shares were purchased. Class C Shares purchased before January 1, 1997, and any
dividend reinvestment plan shares received thereon automatically convert to
Class A Shares ten years after the end of the calendar month in which such
shares were purchased. Such
    
 
                                       31
<PAGE>   280
 
   
conversion will be on the basis of the relative net asset values per share,
without the imposition of any sales load, fee or other charge.
    
 
   
  The conversion of such shares to Class A Shares is subject to the continuing
availability of an opinion of counsel to the effect that (i) the assessment of
the higher distribution and service fees and ACCESS costs with respect to such
shares does not result in the Fund's dividends or distributions constituting
"preferential dividends" under the Code, and (ii) that the conversion of such
shares does not constitute a taxable event under federal income tax law. The
conversion may be suspended if such an opinion is no longer available and such
shares might continue to be subject to the higher aggregate fees applicable to
such class of shares for an indefinite period.
    
 
   
  WAIVER OF CONTINGENT DEFERRED SALES CHARGE. The CDSC is waived on redemptions
of Class B Shares and Class C Shares (i) following the death or disability (as
defined in the Code) of a shareholder, (ii) in connection with required minimum
distributions from an IRA or other retirement plan, (iii) pursuant to the Fund's
systematic withdrawal plan but limited to 12% annually of the initial value of
the account, and (iv) effected pursuant to the right of the Fund to liquidate a
shareholder's account as described herein under "Redemption of Shares." The CDSC
also is waived on redemptions of Class C Shares as it relates to the
reinvestment of redemption proceeds in shares of the same class of the Fund
within 120 days after redemption. See "Shareholder Services" and "Redemption of
Shares" for further discussion of the waiver provisions.
    
 
NET ASSET VALUE
 
  The net asset value per share of the Fund will be determined separately for
each class of shares. The net asset value per share of a given class of shares
of the Fund is determined by calculating the total value of the Fund's assets
attributable to such class of shares, deducting its total liabilities
attributable to such class of shares, and dividing the result by the number of
shares of such class outstanding. The net asset value for the Fund is computed
once daily as of 5:00 p.m. Eastern time Monday through Friday, except on
customary business holidays, or except on any day on which no purchase or
redemption orders are received, or there is not a sufficient degree of trading
in the Fund's portfolio securities such that the Fund's net asset value per
share might be materially affected. The Fund reserves the right to calculate the
net asset value and to adjust the public offering price based thereon more
frequently than once a day if deemed desirable. The net asset value per share of
the different class of shares are expected to be substantially the same; from
time to time, however, the per share net asset value of the different class of
shares may differ.
 
  Portfolio securities are valued by using market quotations, prices provided by
market makers or estimates of market values obtained from yield data relating to
instruments or securities with similar characteristics in accordance with
procedures established in good faith by the Board of Trustees of the Trust, of
which the Fund is
 
                                       32
<PAGE>   281
 
a series. Securities with remaining maturities of 60 days or less are valued at
amortized cost when amortized cost is determined in good faith by or under the
direction of the Board of Trustees of the Trust to be representative of the fair
value at which it is expected such securities may be resold. Any securities or
other assets for which current market quotations are not readily available are
valued at their fair value as determined in good faith under procedures
established by and under the general supervision of the Board of Trustees of the
Trust.
 
- ------------------------------------------------------------------------------
SHAREHOLDER SERVICES
- ------------------------------------------------------------------------------
 
  The Fund offers a number of shareholder services designed to facilitate
investment in its shares at little or no extra cost to the investor. Below is a
description of such services. Unless otherwise described below, each of these
services may be modified or terminated by the Fund at any time.
 
   
  INVESTMENT ACCOUNT. ACCESS, transfer agent for the Fund and a wholly-owned
subsidiary of Van Kampen American Capital, performs bookkeeping, data processing
and administration services related to the maintenance of shareholder accounts.
Each shareholder has an investment account under which shares are held by
ACCESS. Except as described in this Prospectus, after each share transaction in
an account, the shareholder receives a statement showing the activity in the
account. Each shareholder will receive statements at least quarterly from ACCESS
showing any reinvestments of dividends and capital gains distributions and any
other activity in the account since the preceding statement. Such shareholders
also will receive separate confirmations for each purchase or sale transaction
other than reinvestment of dividends and capital gains distributions and
systematic purchases or redemptions. Additions to an investment account may be
made at any time by purchasing shares through authorized brokers, dealers or
financial intermediaries or by mailing a check directly to ACCESS.
    
 
  SHARE CERTIFICATES. Generally, the Fund will not issue share certificates.
However, upon written or telephone request to the Fund, a share certificate will
be issued, representing shares (with the exception of fractional shares) of the
Fund. A shareholder will be required to surrender such certificates upon
redemption thereof. In addition, if such certificates are lost the shareholder
must write to Van Kampen American Capital Funds, c/o ACCESS, P.O. Box 418256,
Kansas City, MO 64141-9256, requesting an "affidavit of loss" and to obtain a
Surety Bond in a form acceptable to ACCESS. On the date the letter is received
ACCESS will calculate a fee for replacing the lost certificate equal to no more
than 2.00% of the net asset value of the issued shares and bill the party to
whom the replacement certificate was mailed.
 
   
  REINVESTMENT PLAN. A convenient way for investors to accumulate additional
shares is by accepting dividends and capital gains distributions in shares of
the Fund. Such shares are acquired at net asset value per share (without sales
charge) on the record date of such dividend or distribution. Unless the
shareholder instructs
    
 
                                       33
<PAGE>   282
 
   
otherwise, the reinvestment plan is automatic. This instruction may be made by
telephone by calling (800) 421-5666 ((800) 421-2833 for the hearing impaired) or
in writing to ACCESS. The investor may, on the initial application or prior to
any declaration, instruct that dividends be paid in cash and capital gains
distributions be reinvested at net asset value, or that both dividends and
capital gains distributions be paid in cash. For further information, see
"Distributions from the Fund."
    
 
  AUTOMATIC INVESTMENT PLAN. An automatic investment plan is available under
which a shareholder can authorize ACCESS to charge a bank account on a regular
basis to invest pre-determined amounts in the Fund. Additional information is
available from the Distributor or authorized brokers, dealers or financial
intermediaries.
 
   
  DIVIDEND DIVERSIFICATION. A shareholder may, upon written request or by
completing the appropriate section of the application form accompanied by this
Prospectus or by calling (800) 421-5666 ((800) 421-2833 for the hearing
impaired), elect to have all dividends and other distributions paid on a class
of shares of the Fund invested into shares of the same class of any other
Participating Fund so long as a pre-existing account for such class of shares
exists for such shareholder.
    
 
  If the qualified pre-existing account does not exist, the shareholder must
establish a new account subject to minimum investment and other requirements of
the fund into which distributions would be invested. Distributions are invested
into the selected fund at its net asset value as of the payable date of the
distribution only if shares of such selected fund have been registered for sale
in the investor's state.
 
   
  EXCHANGE PRIVILEGE. Shares of the Fund may be exchanged with shares of another
Participating Fund, subject to certain limitations. Before effecting an
exchange, shareholders in the Fund should obtain and read a current prospectus
of the fund into which the exchange is to be made. SHAREHOLDERS MAY ONLY
EXCHANGE INTO SUCH OTHER FUNDS AS ARE LEGALLY AVAILABLE FOR SALE IN THEIR STATE.
    
 
  To be eligible for exchange, shares of the Fund must have been registered in
the shareholder's name for at least 30 days prior to an exchange. Shares of the
Fund registered in a shareholder's name for less than 30 days may only be
exchanged upon receipt of prior approval of the Adviser. Under normal
circumstances, it is the policy of the Adviser not to approve such requests.
 
  Class A Shares of Van Kampen American Capital funds that generally impose an
initial sales charge are not subject to any sales charge upon exchange into the
Fund. Class A Shares of Van Kampen American Capital funds that generally do not
impose an initial sales charge are subject to the appropriate sales charge
applicable to Class A Shares of the Fund.
 
   
  No sales charge is imposed upon the exchange of Class B Shares or Class C
Shares. The CDSC schedule and conversion schedule applicable to a Class B Share
or Class C Share acquired through the exchange privilege is determined by
    
 
                                       34
<PAGE>   283
 
reference to the Van Kampen American Capital fund from which such share
originally was purchased. The holding period of a Class B Share or Class C Share
acquired through the exchange privilege is determined by reference to the date
such share originally was purchased from a Van Kampen American Capital fund.
 
  Exchanges of shares are sales and may result in a gain or loss for federal
income tax purposes. If the shares exchanged have been held for less than 91
days, the sales charge paid on such shares is not included in the tax basis of
the exchanged shares, but is carried over and included in the tax basis of the
shares acquired.
 
   
  A shareholder wishing to make an exchange may do so by sending a written
request to ACCESS or by contacting the telephone transaction line at (800)
421-5684 ((800) 421-2833 for the hearing impaired). A shareholder automatically
has telephone exchange privileges unless otherwise designated in the application
form accompanied by this Prospectus. The exchange will take place at the
relative net asset values of the shares next determined after receipt of such
request with adjustment for any additional sales charge. Any shares exchanged
begin earning dividends on the next business day after the exchange is affected.
Van Kampen American Capital and its subsidiaries, including ACCESS
(collectively, "VKAC"), and the Fund employ procedures considered by them to be
reasonable to confirm that instructions communicated by telephone are genuine.
Such procedures include requiring certain personal identification information
prior to acting upon telephone instructions, tape recording telephone
communications, and providing written confirmation of instructions communicated
by telephone. If reasonable procedures are employed, a shareholder agrees that
neither VKAC nor the Fund will be liable for following telephone instructions
which it reasonably believes to be genuine. VKAC and the Fund may be liable for
any losses due to unauthorized or fraudulent instructions if reasonable
procedures are not followed. Exchanges are effected at the net asset value per
share next calculated after the request is received in good order with
adjustment for any additional sales charge. If the exchanging shareholder does
not have an account in the fund whose shares are being acquired, a new account
will be established with the same registration, dividend and capital gains
options (except dividend diversification options) and broker, dealer or
financial intermediary of record as the account from which shares are exchanged,
unless otherwise specified by the shareholder. In order to establish a
systematic withdrawal plan for the new account or reinvest dividends from the
new account into another fund, an exchanging shareholder must file a specific
written request. The Fund reserves the right to reject any order to acquire
shares through exchange. In addition, the Fund may modify, restrict or terminate
the exchange privilege at any time on 60 days' notice to its shareholders of any
termination or material amendment.
    
 
   
  A prospectus of any of these mutual funds may be obtained from any broker,
dealer or financial intermediary or the Distributor. An investor considering an
exchange to one of such funds should refer to the prospectus for additional
information regarding such fund prior to investing.
    
 
                                       35
<PAGE>   284
 
   
  SYSTEMATIC WITHDRAWAL PLAN. Any investor whose shares in a single account
total $10,000 or more at the offering price next computed after receipt of
instructions may establish a monthly, quarterly, semi-annual or annual
withdrawal plan. Any investor whose shares in a single account total $5,000 or
more at the offering price next computed after receipt of instructions may
establish a quarterly, semi-annual or annual withdrawal plan. This plan provides
for the orderly use of the entire account, not only the income but also the
capital, if necessary. Each withdrawal constitutes a redemption of shares on
which taxable gain or loss will be recognized. The plan holder may arrange for
monthly, quarterly, semi-annual, or annual checks in any amount not less than
$25.
    
 
   
  Holders of Class B Shares and Class C Shares who establish a withdrawal plan
may redeem up to 12% annually of the shareholder's initial account balance
without incurring a contingent deferred sales charge. Initial account balance
means the amount of the shareholder's investment at the time the election to
participate in the plan is made.
    
 
  Under the plan, sufficient shares of the Fund are redeemed to provide the
amount of the periodic withdrawal payment. Dividends and capital gains
distributions on shares held under the plan are reinvested in additional shares
at the next determined net asset value. If periodic withdrawals continuously
exceed reinvested dividends and capital gains distributions, the shareholder's
original investment will be correspondingly reduced and ultimately exhausted.
Withdrawals made concurrently with purchases of additional shares ordinarily
will be disadvantageous to the shareholder because of the duplication of sales
charges. The Fund reserves the right to amend or terminate the systematic
withdrawal program on thirty days' notice to its shareholders.
 
  CHECK WRITING PRIVILEGE. Holders of Class A Shares of the Fund for which
certificates have not been issued and which are in a non-escrow status may
appoint ACCESS as agent by completing the Authorization for Redemption by Check
Form and the appropriate section of the application and returning the form and
the application to ACCESS. Once the form is properly completed, signed and
returned to the agent, a supply of checks drawn on State Street Bank and Trust
Company ("State Street Bank") will be sent to such shareholder. These checks may
be made payable by the holder of Class A Shares to the order of any person in
any amount of $100 or more.
 
  When a check is presented to State Street Bank for payment, full and
fractional Class A Shares required to cover the amount of the check are redeemed
from the shareholder's account by ACCESS at the next determined net asset value.
Check writing redemptions represent the sale of Class A Shares. Any gain or loss
realized on the sale of Class A Shares is a taxable event. See "Redemption of
Shares."
 
  Checks will not be honored for redemption of Class A Shares held less than 15
calendar days, unless such Class A Shares have been paid for by bank wire. Any
Class A Shares for which there are outstanding certificates may not be redeemed
by
 
                                       36
<PAGE>   285
 
   
check. If the amount of the check is greater than the proceeds of all
uncertificated shares held in the shareholder's Class A Share account, the check
will be returned and the shareholder may be subject to additional charges.
Holders of Class A Shares may not liquidate the entire account by means of a
check. The check writing privilege may be terminated or suspended at any time by
the Fund or State Street Bank. Retirement plans and accounts that are subject to
backup withholding are not eligible for the privilege. A "stop payment" system
is not available on these checks. See the Statement of Additional Information
for further information regarding the establishment of the privilege.
    
 
  AUTOMATED CLEARING HOUSE ("ACH") DEPOSITS. Holders of Class A Shares can use
ACH to have redemption proceeds deposited electronically into their bank
accounts. Redemptions transferred to a bank account via the ACH plan are
available to be credited to the account on the second business day following
normal payment. In order to utilize this option, the shareholder's bank must be
a member of Automated Clearing House. In addition, the shareholder must fill out
the appropriate section of the account application. The shareholder must also
include a voided check or deposit slip from the bank account into which
redemptions are to be deposited together with the completed application. Once
ACCESS has received the application and the voided check or deposit slip, such
shareholder's designated bank account, following any redemption, will be
credited with the proceeds of such redemption. Once enrolled in the ACH plan, a
shareholder may terminate participation at any time by writing ACCESS.
 
- ------------------------------------------------------------------------------
REDEMPTION OF SHARES
- ------------------------------------------------------------------------------
 
  Shareholders may redeem for cash some or all of their shares without charge by
the Fund (other than, with respect to CDSC Shares, the applicable contingent
deferred sales charge) at any time by sending a written request in proper form
directly to ACCESS, P. O. Box 418256, Kansas City, Missouri 64141-9256, by
placing the redemption request through an authorized dealer or by calling the
Fund.
 
  WRITTEN REDEMPTION REQUESTS. In the case of redemption requests sent directly
to ACCESS, the redemption request should indicate the number of shares to be
redeemed, the class designation of such shares, the account number and be signed
exactly as the shares are registered. Signatures must conform exactly to the
account registration. If the proceeds of the redemption would exceed $50,000, or
if the proceeds are not to be paid to the record owner at the record address, or
if the record address has changed within the previous 30 days, signature(s) must
be guaranteed by one of the following: a bank or trust company; a broker-dealer;
a credit union; a national securities exchange, registered securities
association or clearing agency; a savings and loan association; or a federal
savings bank. If certificates are held for the shares being redeemed, such
certificates must be endorsed for transfer or accompanied by an endorsed stock
power and sent with the redemption request. In the event the redemption is
requested by a corporation,
 
                                       37
<PAGE>   286
 
partnership, trust, fiduciary, executor or administrator, and the name and title
of the individual(s) authorizing such redemption is not shown in the account
registration, a copy of the corporate resolution or other legal documentation
appointing the authorized signer and certified within the prior 60 days must
accompany the redemption request. The redemption price is the net asset value
per share next determined after the request is received by ACCESS in proper
form. Payment for shares redeemed (less any sales charge, if applicable) will
ordinarily be made by check mailed within three business days after acceptance
by ACCESS of the request and any other necessary documents in proper order. Such
payments may be postponed or the right of redemption suspended as provided by
the rules of the SEC. If the shares to be redeemed have been recently purchased
by check, ACCESS may delay mailing a redemption check until it confirms that the
purchase check has cleared, usually a period of up to 15 days. Any gain or loss
realized on the redemption of shares is a taxable event.
 
  DEALER REDEMPTION REQUESTS. Shareholders may sell shares through their
securities dealer, who will telephone the request to the Distributor. Orders
received from dealers must be at least $500 unless transmitted via the FUNDSERV
network. The redemption price for such shares is the net asset value next
calculated after an order is received by a dealer provided such order is
transmitted to the Distributor prior to the Distributor's close of business on
such day. It is the responsibility of dealers to transmit redemption requests
received by them to the Distributor so they will be received prior to such time.
Any change in the redemption price due to failure of the Distributor to receive
a sell order prior to such time must be settled between the shareholder and
dealer. Shareholders must submit a written redemption request in proper form (as
described above under "Written Redemption Requests") to the dealer within three
business days after calling the dealer with the sell order. Payment for shares
redeemed (less any sales charge, if applicable) will ordinarily be made by check
mailed within three business days to the dealer.
 
   
  TELEPHONE REDEMPTION REQUESTS. The Fund permits redemption of shares by
telephone and for redemption proceeds to be sent to the address of record for
the account or to the bank account of record as described below. To establish
such privilege, a shareholder must complete the appropriate section of the
application accompanying this Prospectus or call the Fund at (800) 421-5666
((800) 421-2833 for the hearing impaired) to request that a copy of the
Telephone Redemption Authorization form be sent to them for completion. To
redeem shares, contact the telephone transaction line at (800) 421-5684. VKAC
and the Fund employ procedures considered by them to be reasonable to confirm
that instructions communicated by telephone are genuine. Such procedures include
requiring certain personal identification information prior to acting upon
telephone instructions, tape recording telephone communications, and providing
written confirmation of instructions communicated by telephone. If reasonable
procedures are employed, a shareholder agrees that neither VKAC nor the Fund
will be liable for following instructions which it reasonably believes to be
genuine. VKAC and the Fund may be liable for any losses due to unauthorized or
fraudulent instructions if reasonable
    
 
                                       38
<PAGE>   287
 
procedures are not followed. Telephone redemptions may not be available if the
shareholder cannot reach ACCESS by telephone, whether because all telephone
lines are busy or for any other reason; in such case, a shareholder would have
to use the Fund's other redemption procedures previously described. Requests
received by ACCESS prior to 4:00 p.m., New York time, on a regular business day
will be processed at the net asset value per share determined that day. These
privileges are available for all accounts other than retirement accounts. The
telephone redemption privilege is not available for shares represented by
certificates. If the shares to be redeemed have been recently purchased by
check, ACCESS may delay mailing a redemption check or wiring redemption proceeds
until it confirms that the purchase check has cleared, usually a period of up to
15 days. If an account has multiple owners, ACCESS may rely on the instructions
of any one owner.
 
  For redemptions authorized by telephone, amounts of $50,000 or less may be
redeemed daily if the proceeds are to be paid by check sent to the shareholders'
address of record and amounts of at least $1,000 and up to $1 million may be
redeemed daily if the proceeds are to be paid by wire sent to the shareholder's
bank account of record. The proceeds must be payable to the shareholder(s) of
record. Proceeds from redemptions to be paid by check will ordinarily be mailed
within three business days to the shareholder's address of record. Proceeds from
redemptions to be paid by wire will ordinarily be wired on the next business day
to the shareholder's bank account of record. This privilege is not available if
the address of record has been changed within 30 days prior to a telephone
redemption request. The Fund reserves the right at any time to terminate, limit
or otherwise modify this telephone redemption privilege.
 
   
  REDEMPTION UPON DISABILITY. The Fund will waive the CDSC on redemptions
following the disability of holders of Class B Shares and Class C Shares. An
individual will be considered disabled for this purpose if he or she meets the
definition thereof in Section 72(m)(7) of the Code, which in pertinent part
defines a person as disabled if such person "is unable to engage in any
substantial gainful activity by reason of any medically determinable physical or
mental impairment which can be expected to result in death or to be of
long-continued and indefinite duration." While the Fund does not specifically
adopt the balance of the Code's definition which pertains to furnishing the
Secretary of Treasury with such proof as he or she may require, the Distributor
will require satisfactory proof of disability before it determines to waive the
CDSC on Class B Shares and Class C Shares.
    
 
   
  In cases of disability, the CDSCs on Class B Shares and Class C Shares will be
waived where the disabled person is either an individual shareholder or owns the
shares as a joint tenant with right of survivorship or is the beneficial owner
of a custodial or fiduciary account, and where the redemption is made within one
year of the initial determination of disability. This waiver of the CDSC on
Class B Shares and Class C Shares applies to a total or partial redemption, but
only to redemptions of shares held at the time of the initial determination of
disability.

  GENERAL REDEMPTION INFORMATION. The Fund may redeem any shareholder account
with a net asset value on the date of the notice of redemption less than the
minimum investment as specified by the Trustees. At least 60 days advance
written notice of any such involuntary redemption is required and the
shareholder is given an opportunity to purchase the required value of additional
shares at the next determined net asset value without sales charge. Any
applicable CDSC will be deducted from the proceeds of this redemption. Any
involuntary redemption may only occur if the shareholder account is less than
the minimum investment due to shareholder redemptions.
    
 
   
  REINSTATEMENT PRIVILEGE. Holders of Class A Shares or Class B Shares who have
redeemed shares of the Fund may reinstate any portion or all of the net proceeds
of such redemption in Class A Shares of the Fund. Holders of Class C Shares who
have redeemed shares of the Fund may reinstate any portion or all of the net
proceeds of such redemption in Class C Shares of the Fund with credit given for
any CDSC paid upon such redemption. Such reinstatement is made at the net asset
value (without sales charge except as described under "Shareholder
Services -- Exchange Privilege") next determined after the order is received,
which must be within 180 days after the date of the redemption. See "Purchase of
Shares -- Waiver of Contingent Deferred Sales Charge." Reinstatement at net
asset value is also offered to participants in those eligible retirement plans
held or administered by Van Kampen American Capital Trust Company for repayment
of principal (and interest) on their borrowings on such plans.
    
 
- ------------------------------------------------------------------------------
   
DISTRIBUTION AND SERVICE PLANS
    
- ------------------------------------------------------------------------------
 
  The Fund has adopted a distribution plan (the "Distribution Plan") with
respect to each class of its shares pursuant to Rule 12b-1 under the 1940 Act.
The Fund also has adopted a service plan (the "Service Plan") with respect to
each class of its shares. The Distribution Plan and the Service Plan provide
that the Fund may spend a portion of the Fund's average daily net assets
attributable to each class of shares in connection with distribution of the
respective class of shares and in connection with the provision of ongoing
services to shareholders of each class. The Distribution Plan and the Service
Plan are being implemented through an agreement with the Distributor and
sub-agreements between the Distributor and brokers, dealers or financial
intermediaries (collectively, "Selling Agreements") that may provide for their
customers or clients certain services or assistance.
 
  CLASS A SHARES. The Fund may spend an aggregate amount up to 0.25% per year of
the average daily net assets attributable to the Class A Shares of the Fund
pursuant to the Distribution Plan and Service Plan. From such amount, the Fund
may spend up to 0.25% per year of the Fund's average daily net assets
attributable to the Class A Shares pursuant to the Service Plan in connection
with the ongoing provision of services to holders of such shares by the
Distributor and by brokers, dealers or financial intermediaries and in
connection with the maintenance of such
 
                                       40
<PAGE>   289
 
   
shareholders' accounts. The Fund pays the Distributor the lesser of the balance
of the 0.25% not paid to such brokers, dealers or financial intermediaries or
the amount of the Distributor's actual distribution-related expense.
    
 
  CLASS B SHARES. The Fund may spend up to 0.75% per year of the average daily
net assets attributable to the Class B Shares of the Fund pursuant to the
Distribution Plan. In addition, the Fund may spend up to 0.25% per year of the
Fund's average daily net assets attributable to the Class B Shares pursuant to
the Service Plan in connection with the ongoing provision of services to holders
of such shares by the Distributor and by brokers, dealers or financial
intermediaries and in connection with the maintenance of such shareholders'
accounts.
 
   
  CLASS C SHARES. The Fund may spend up to 0.75% per year of the average daily
net assets attributable to the Class C Shares of the Fund pursuant to the
Distribution Plan. From such amount, the Fund, or the Distributor as agent for
the Fund, pays brokers, dealers or financial intermediaries in connection with
the distribution of the Class C Shares up to 0.75% of the Fund's average daily
net assets attributable to Class C Shares maintained in the Fund more than one
year by such broker's, dealer's or financial intermediary's customers. The Fund
pays the Distributor the lesser of the balance of 0.75% not paid to such
brokers, dealers or financial intermediaries or the amount of the Distributor's
actual distribution-related expense attributable to the Class C Shares. In
addition, the Fund may spend up to 0.25% per year of the Fund's average daily
net assets attributable to the Class C Shares pursuant to the Service Plan in
connection with the ongoing provision of services to holders of such shares by
the Distributor and by brokers, dealers or financial intermediaries and in
connection with the maintenance of such shareholders' accounts.
    
 
  OTHER INFORMATION. Amounts payable to the Distributor with respect to the
Class A Shares under the Distribution Plan in a given year may not fully
reimburse the Distributor for its actual distribution-related expenses during
such year. In such event, with respect to the Class A Shares, there is no
carryover of such reimbursement obligations to succeeding years.
 
   
  The Distributor's actual expenses with respect to a class of CDSC Shares (for
purposes of this section, excluding any Class A Shares that may be subject to a
CDSC) for any given year may exceed the amounts payable to the Distributor with
respect to such class of CDSC Shares under the Distribution Plan, the Service
Plan and payments received pursuant to the CDSC. In such event, with respect to
any such class of CDSC Shares, any unreimbursed expenses will be carried forward
and paid by the Fund (up to the amount of the actual expenses incurred) in
future years so long as such Distribution Plan is in effect. Except as mandated
by applicable law, the Fund does not impose any limit with respect to the number
of years into the future that such unreimbursed expenses may be carried forward
(on a Fund level basis). Because such expenses are accounted on a Fund level
basis, in periods of extreme net asset value fluctuation such amounts with
respect to a particular CDSC Share may be greater or less than the amount of the
initial commission (including
    
 
                                       41
<PAGE>   290
 
   
carrying cost) paid by the Distributor with respect to such CDSC Share. In such
circumstances, a shareholder of such CDSC Share may be deemed to incur expenses
attributable to other shareholders of such class. As of December 31, 1996, there
were $809,471 and $3,825 of unreimbursed distribution-related expenses with
respect to Class B Shares and Class C Shares, respectively, representing 4.29%
and 0.45% of the Fund's net assets attributable to Class B Shares and Class C
Shares, respectively. If the Distribution Plan was terminated or not continued,
the Fund would not be contractually obligated to pay the Distributor for any
expenses not previously reimbursed by the Fund or recovered through CDSCs.
    
 
   
  Because the Fund is a series of the Trust, amounts paid to the Distributor as
reimbursement for expenses of one series of the Trust may indirectly benefit the
other funds which are series of the Trust. The Distributor will endeavor to
allocate such expenses among such funds in an equitable manner. The Distributor
will not use the proceeds from the CDSC applicable to a particular class of
shares to defray distribution-related expenses attributable to any other class
of shares. Various federal and state laws prohibit national banks and some
state-chartered commercial banks from underwriting or dealing in the Fund's
shares. In addition, state securities laws on this issue may differ from the
interpretations of federal law, and banks and financial institutions may be
required to register as dealers pursuant to state law. In the unlikely event
that a court were to find that these laws prevent such banks from providing such
services described above, the Fund would seek alternate providers and expects
that shareholders would not experience any disadvantage.
    
 
- ------------------------------------------------------------------------------
DISTRIBUTIONS FROM THE FUND
- ------------------------------------------------------------------------------
 
  The Fund's present policy, which may be changed at any time by the Board of
Trustees, is to declare daily and pay monthly distributions of all or
substantially all net investment income of the Fund. Net investment income
consists of all interest income and dividends, other ordinary income earned by
the Fund, less all expenses of the Fund attributable to the class of shares in
question. Net short-term capital gains, if any, may be distributed throughout
the year. Expenses of the Fund are accrued each day. Net realized long-term
capital gains, if any, are expected to be distributed, to the extent permitted
by applicable law, to shareholders at least annually. Distributions cannot be
assured, and the amount of each monthly distribution may vary.
 
  Distributions with respect to each class of shares will be calculated in the
same manner on the same day and will be in the same amount, except that the
different distribution and service fees and any incremental administrative
expenses relating to each class of shares will be borne exclusively by the
respective class and may cause the distributions relating to the different
classes of shares to differ. Generally, distributions with respect to a class of
shares subject to a higher distribution fee will be lower than distributions
with respect to a class of shares subject to a lower distribution fee.

  Investors will be entitled to begin receiving dividends on their shares on the
business day after ACCESS receives payments for such shares. However, shares
become entitled to dividends on the day ACCESS receives payment for the shares
either through a fed wire or NSCC settlement. Shares remain entitled to
dividends through the day such shares are processed for payment on redemption.
    
 
  Distribution checks may be sent to parties other than the shareholder in whose
name the account is registered. Persons wishing to utilize this service should
complete the appropriate section of the account application accompanying this
Prospectus or available from Van Kampen American Capital Funds, c/o ACCESS, P.O.
Box 418256, Kansas City, MO 64141-9256. After ACCESS receives this completed
form, distribution checks will be sent to the bank or other person so designated
by such shareholder.
 
   
  PURCHASE OF ADDITIONAL SHARES WITH DISTRIBUTIONS.  The Fund will automatically
credit monthly distributions and any annual net long-term capital gain
distributions to a shareholder's account in additional shares of the Fund valued
at net asset value, without a sales charge. Unless a shareholder elects
otherwise, the reinvestment plan is automatic. This instruction may be made by
telephone by calling (800) 421-5666 ((800) 421-2833 for the hearing impaired) or
in writing to ACCESS. See "Shareholder Services -- Reinvestment Plan."

TAX STATUS
- ------------------------------------------------------------------------------
 
FLORIDA TAXATION
 
   
  The following Florida tax discussion is based on the advice of Squire, Sanders
& Dempsey L.L.P., special counsel to the Fund for Florida tax matters.
    
 
  Under existing Florida law, shares of the Fund will not be subject to the
Florida intangible personal property tax for any year if, on the last business
day of the previous calendar year, the Fund's portfolio consisted solely of (1)
notes, bonds and other obligations issued by the State of Florida or its
municipalities, counties, and other taxing districts, or by the United States
Government and its agencies, or by the governments of Puerto Rico, Guam or the
U.S. Virgin Islands, or (2) other intangible personal property exempt from the
Florida intangible personal property tax. (FOR THIS PURPOSE, OBLIGATIONS ISSUED
BY A NONPROFIT CORPORATION FORMED UNDER THE GENERAL NONPROFIT CORPORATION LAW OF
A STATE ARE NOT EXEMPT FROM THE FLORIDA INTANGIBLE PERSONAL PROPERTY TAX EVEN IF
THEY ARE CONSIDERED FOR FEDERAL INCOME TAX PURPOSES TO BE OBLIGATIONS ISSUED "ON
BEHALF OF" A GOVERNMENTAL UNIT THE INTEREST ON WHICH IS EXEMPT FROM FEDERAL
INCOME TAX.) Shares of the Fund will generally be subject to the Florida
intangible personal property tax for any year if, on the last business day of
the previous calendar year, the Fund's portfolio consists of any asset that is
not exempt from the Florida intangible property tax.
 
                                       43
<PAGE>   292
 
  The State of Florida and its political subdivisions do not impose income taxes
on individuals, and therefore individual shareholders of the Fund will not be
subject to a Florida income tax on distributions from the Fund or on gain from
the sale or other disposition of shares of the Fund.
 
  Corporations (and certain other entities treated as corporations under the
Florida Income Tax Code) that are subject to the Florida income tax will be
taxable on distributions from the Fund and on gain from the sale or other
disposition of shares of the Fund to the extent such income or gain is allocated
or apportioned to Florida. Accordingly, investment in shares of the Fund may not
be appropriate for such corporations.
 
  The transfer of shares of the Fund will not be subject to the Florida
documentary stamp tax. Shares of the Fund will be included in assets subject to
Florida estate tax.
 
   
  Under current Florida tax law, the Florida intangible personal property tax
rate is $2.00 per $1,000 of taxable intangible property. Shareholders subject to
taxation in a state other than Florida may realize a lower after-tax rate of
return than Florida shareholders if the dividends distributed by the Fund are
not exempt from taxation in such other state.
    
 
FEDERAL TAXATION
 
   
  The following federal income tax discussion is based on the advice of Skadden,
Arps, Slate, Meagher & Flom (Illinois).
    
 
   
  FEDERAL INCOME TAXATION.  The Fund has qualified and intends to continue to
qualify each year and to elect to be treated as a regulated investment company
under Subchapter M of the Code. To qualify as a regulated investment company,
the Fund must comply with certain requirements of the Code relating to, among
other things, the source of its income and diversification of its assets.
    
 
   
  If the Fund so qualifies and distributes each year to its shareholders at
least 90% of its net investment income (including tax-exempt interest, taxable
income and net short-term capital gain, but not net capital gains, which are the
excess of net long-term capital gains over net short-term capital losses), it
will not be required to pay federal income taxes on any income distributed to
shareholders. The Fund intends to distribute at least the minimum amount of net
investment income necessary to satisfy the 90% distribution requirement. The
Fund will not be subject to federal income tax on any net capital gains
distributed to shareholders.
    
 
   
  In order to avoid a 4% excise tax, the Fund will be required to distribute, by
December 31 of each year, at least 98% of its ordinary income (not including
tax-exempt income) for such year and at least 98% of its capital gain net income
(the latter of which generally is computed on the basis of the one-year period
ending on October 31 of such year), plus any amounts that were not distributed
in previous
    
 
                                       44
<PAGE>   293
 
   
taxable years. For purposes of the excise tax, any ordinary income or capital
gain net income retained by, and subject to federal income tax in the hands of,
the Fund will be treated as having been distributed.
    
 
   
  If the Fund failed to qualify as a regulated investment company or failed to
satisfy the 90% distribution requirement in any taxable year, the Fund would be
taxed as an ordinary corporation on its taxable income (even if such income were
distributed to its shareholders) and all distributions out of earnings and
profits would be taxed to shareholders as ordinary income. To qualify again as a
regulated investment company in a subsequent year, the Fund may be required to
pay an interest charge on 50% of its earnings and profits attributable to
non-regulated investment company years and would be required to distribute such
earnings and profits to shareholders (less any interest charge). In addition, if
the Fund failed to qualify as a regulated investment company for its first
taxable year or, if immediately after qualifying as a regulated investment
company for any taxable year, it failed to qualify for a period greater than one
taxable year, the Fund would be required to recognize any net built-in gains
(the excess of aggregate gains, including items of income, over aggregate losses
that would have been realized if it had been liquidated) in order to qualify as
a regulated investment company in a subsequent year.
    
 
   
  Some of the Fund's investment practices are subject to special provisions of
the Code that, among other things, may defer the use of certain losses of the
Fund and affect the holding period of the securities held by the Fund and the
character of the gains or losses realized by the Fund. These provisions may also
require the Fund to mark-to-market some of the positions in its portfolio (i.e.,
treat them as if they were sold for fair market value at the end of the
tax-year), which may cause the Fund to recognize income without receiving cash
with which to make distributions in amounts necessary to satisfy the 90%
distribution requirement and the distribution requirements for avoiding income
and excise taxes. The Fund will monitor its transactions and may make certain
tax elections in order to mitigate the effect of these rules and prevent
disqualification of the Fund as a regulated investment company.
    
 
   
  The Fund's ability to dispose of portfolio securities may be limited by the
requirement for qualification as a regulated investment company that less than
30% of the Fund's annual gross income be derived from the disposition of
securities held for less than three months.
    
 
   
  Investments of the Fund in securities issued at a discount or providing for
deferred interest or payment of interest in kind are subject to special tax
rules that will affect the amount, timing and character of distributions to
shareholders. For example, with respect to securities issued at a discount, the
Fund will be required to accrue as income each year a portion of the discount
and to distribute such income each year in order to maintain its qualification
as a regulated investment company and to avoid income and excise taxes. In order
to generate sufficient cash to make distributions necessary to satisfy the 90%
distribution requirement and to avoid
    
 
                                       45
<PAGE>   294
 
   
income and excise taxes, the Fund may have to dispose of securities that it
would otherwise have continued to hold. A portion of the discount relating to
certain stripped tax-exempt obligations may constitute taxable income when
distributed to shareholders.
    
 
   
  DISTRIBUTIONS.  The Fund intends to invest in sufficient tax-exempt municipal
securities to permit payment of "exempt-interest dividends" (as defined in the
Code). Dividends paid by the Fund from the net tax-exempt interest earned from
municipal securities qualify as exempt-interest dividends if, at the close of
each quarter of its taxable year, at least 50% of the value of the total assets
of the Fund consists of municipal securities.
    
 
   
  The Tax Reform Act of 1986 (the "Tax Reform Act") may have an adverse impact
upon the Fund and its shareholders. The Tax Reform Act imposed new limitations
on the use and investment of the proceeds of state and local government bonds
and other funds, which limitations must be satisfied in order to maintain the
exclusion from gross income for interest on such bonds. The provisions of the
Tax Reform Act generally apply to bonds issued after August 15, 1986. In light
of these requirements, bond counsel qualify their opinions as to the federal tax
status of bonds issued after August 15, 1986 by making them contingent on the
issuer's future compliance with these limitations. Any failure on the part of an
issuer to comply could cause the interest on its bonds to become taxable to
investors retroactive to the date the bonds were issued.
    
 
   
  Except as provided below, exempt-interest dividends paid to shareholders
generally are not includable in the shareholders' gross income for federal
income tax purposes. The percentage of the total dividends paid by the Fund
during any taxable year that qualify as exempt-interest dividends will be the
same for all shareholders of the Fund receiving dividends during such year.
    
 
   
  The Tax Reform Act also makes interest on certain "private-activity bonds" an
item of tax preference subject to the alternative minimum tax on individuals and
corporations. The Fund invests a portion of its assets in municipal securities
subject to this provision so that a portion of its exempt-interest dividends is
an item of tax preference to the extent such dividends represent interest
received from these private-activity bonds. Accordingly, investment in the Fund
could cause shareholders to be subject to (or result in an increased liability
under) the alternative minimum tax. The Tax Reform Act also imposed per capita
volume limitations on certain private-activity bonds which could limit the
amount of such bonds available for investment by the Fund.
    
 
   
  Exempt-interest dividends are included in determining what portion, if any, of
a person's social security and railroad retirement benefits will be includable
in gross income subject to federal income tax.
    
 
   
  Although exempt-interest dividends generally may be treated by Fund
shareholders as items of interest excluded from their gross income, each
shareholder is advised to consult his tax adviser with respect to whether
exempt-interest dividends
    
 
                                       46
<PAGE>   295
 
   
retain this exclusion if the purchaser would be treated as a "substantial user"
(or a "related person" of a substantial user) of the facilities financed with
respect to any of the tax-exempt obligations held by the Fund, or by the Trust
if it is required to qualify as a regulated investment company as described
below. "Substantial user" is defined under U.S. Treasury Regulations to include
a non-exempt person who regularly uses in his trade or business a part of any
facilities financed with the tax-exempt obligations and whose gross revenues
derived from such facilities exceed five percent of the total revenues derived
from the facilities by all users, or who occupies more than 5% of the useable
area of the facilities or for whom the facilities or a part thereof were
specifically constructed, reconstructed or acquired. Examples of "related
persons" include certain related natural persons, affiliated corporations, a
partnership and its partners and an S corporation and its shareholders.
    
 
   
  The Omnibus Budget Reconciliation Act of 1993 included certain provisions that
requires gains on dispositions of tax-exempt securities purchased at a market
discount be treated as ordinary income to the extent of the accrued market
discount, if the securities are acquired after April 30, 1993. Such securities
were exempt from the market discount rules under prior law. Interest on
indebtedness incurred or continued by a shareholder to purchase or carry shares
of the Fund is not deductible for federal income tax purposes if the Fund
distributes exempt-interest dividends during the shareholder's taxable year. If
a shareholder receives an exempt-interest dividend with respect to any shares
and such shares are held for six months or less, any short-term capital loss on
the sale or exchange of the shares will be disallowed to the extent of the
amount of such exempt-interest dividend.
    
 
   
  While the Fund expects that a major portion of its net investment income will
constitute tax-exempt interest, a significant portion may consist of investment
company taxable income. Distributions of the Fund's net investment company
taxable income are taxable to shareholders as ordinary income to the extent of
the Fund's earnings and profits, whether paid in cash or reinvested in
additional shares. Distributions of the Fund's net capital gains ("capital gains
dividends"), if any, are taxable to shareholders as long-term capital gains
regardless of the length of time shares of the Fund have been held by such
shareholders. Interest on indebtedness which is incurred to purchase or carry
shares of a mutual fund which distributes exempt-interest dividends during the
year is not deductible for federal income tax purposes. Distributions in excess
of the Fund's earnings and profits will first reduce the adjusted tax basis of a
holder's shares and, after such adjusted tax basis is reduced to zero, will
constitute capital gains to such holder (assuming such shares are held as a
capital asset). Tax-exempt shareholders not subject to federal income tax on
their income generally will not be taxed on distributions from the Fund.
    
 
   
  Shareholders receiving distributions in the form of additional shares issued
by the Fund will be treated for federal income tax purposes as receiving a
distribution in an amount equal to the fair market value of the shares received,
determined as of the distribution date. The basis of such shares will equal the
fair market value on the distribution date.
    
 
                                       47
<PAGE>   296
 
   
  The Fund will inform shareholders of the source and tax status of all
distributions promptly after the close of each calendar year. The aggregate
amount of dividends so designated cannot exceed, however, the amount of interest
exempt from tax under Section 103 of the Code received by the Fund during the
year over any amounts disallowed as deductions under Sections 265 and 171(a)(2)
of the Code. Since the percentage of dividends which are "exempt-interest"
dividends is determined on an average annual method for the fiscal year, the
percentage of income designated as tax-exempt for any particular dividend may be
substantially different from the percentage of the Fund's income that was tax
exempt during the period covered by the dividend, Fund distributions generally
will not qualify for the dividends received deduction for corporations.
    
 
   
  Although dividends generally will be treated as distributed when paid,
dividends declared in October, November or December, payable to shareholders of
record on a specified date in such month and paid during January of the
following year will be treated as having been distributed by the Fund and
received by the shareholders on the December 31 prior to the date of payment. In
addition, certain other distributions made after the close of a taxable year of
the Fund may be "spilled back" and treated as paid by the Fund (except for
purposes of the 4% excise tax) during such taxable year. In such case,
shareholders will be treated as having received such dividends in the taxable
year in which the distribution was actually made.
    
 
   
  The Fund is required, in certain circumstances, to withhold 31% of dividends
and certain other payments, including redemptions, paid to shareholders who do
not furnish to the Fund their correct taxpayer identification number (in the
case of individuals, their social security number) and certain required
certifications or who are otherwise subject to backup withholding.
    
 
   
  SALE OF SHARES.  The sale of shares (including transfers in connection with a
redemption or repurchase of shares) will be a taxable transaction for federal
income tax purposes. Selling shareholders will generally recognize gain or loss
in an amount equal to the difference between their adjusted tax basis in the
shares and the amount received. If such shares are held as a capital asset, the
gain or loss will be a capital gain or loss and will be long-term if such shares
have been held for more than one year. Any loss realized upon a taxable
disposition of shares held for six months or less will be treated as a long-term
capital loss to the extent of any capital gains dividends received with respect
to such shares. For purposes of determining whether shares have been held for
six months or less, the holding period is suspended for any periods during which
the shareholder's risk of loss is diminished as a result of holding one or more
other positions in substantially similar or related property or through certain
options or short sales.
    
 
   
  GENERAL.  The federal, state and local income tax discussion set forth above
is for general information only. Prospective investors should consult their
advisors regarding the specific federal tax consequences of holding and
disposing of shares, as well as the effects of state, local and foreign tax law
and any proposed tax law changes.

FUND PERFORMANCE
- ------------------------------------------------------------------------------
 
   
  From time to time advertisements and other sales materials for the Fund may
include information concerning the historical performance of the Fund. Any such
information will include the average total return of the Fund calculated on a
compounded basis for specified periods of time. Such advertisements and sales
material may also include a yield quotation as of a current period. In each
case, such total return and yield information, if any, will be calculated
pursuant to rules established by the SEC and will be computed separately for
each class of the Fund's shares. In lieu of or in addition to total return and
yield calculations, such information may include performance rankings and
similar information from independent organizations such as Lipper Analytical
Services, Inc. or nationally recognized financial publications.
    
 
   
  From time to time, the Fund may include in its sales literature and
shareholder reports a quotation of the current "distribution rate" for each
class of shares of the Fund. Distribution rate is a measure of the level of
income and short-term capital gain dividends, if any, distributed for a
specified period. Distribution rate is determined by annualizing the
distributions per share for a stated period and dividing the result by the
public offering price for the same period. It differs from yield, which is a
measure of the income actually earned by the Fund's investments, and from total
return, which is a measure of the income actually earned by, plus the effect of
any realized and unrealized appreciation or depreciation of such investments
during a stated period. Distribution rate is, therefore, not intended to be a
complete measure of the Fund's performance. Distribution rate may sometimes be
greater than yield since, for instance, it may not include the effect of
amortization of bond premiums, and may include non-recurring short-term capital
gains and premiums from futures transactions engaged in by the Fund.
Distribution rates will be computed separately for each class of the Fund's
shares.
    
 
  From time to time, the Fund may compare its performance to certain securities
and unmanaged indices which may have different risk/reward characteristics than
the Fund. Such characteristics may include, but are not limited to, tax
features, guarantees, insurance and the fluctuation of principal or return. In
addition, from time to time, the Fund may utilize sales literature that includes
hypotheticals.

DESCRIPTION OF SHARES OF THE FUND
- ------------------------------------------------------------------------------
 
  The Fund is a series of the Van Kampen American Capital Tax Free Trust, a
Delaware business trust organized as of May 10, 1995 (the "Trust"). The Fund was
 
                                       49
<PAGE>   298
 
originally organized in 1994 under the name Van Kampen Merritt Florida Insured
Tax Free Fund as a sub-trust of the Van Kampen Merritt Tax Free Fund, a
Massachusetts business trust. The Fund was reorganized as a series of the Trust
as of July 31, 1995. Shares of the Trust entitle their holders to one vote per
share; however, separate votes are taken by each series on matters affecting an
individual series.
 
   
  The authorized capitalization of the Fund consists of an unlimited number of
shares of beneficial interest, $0.01 par value, divided into three classes,
designated Class A Shares, Class B Shares and Class C Shares. Each class of
shares represents an interest in the same assets of the Fund and are identical
in all respects except that each class bears certain distribution expenses and
has exclusive voting rights with respect to its distribution fee. See
"Distribution and Service Plans."
    
 
   
  The Fund is permitted to issue an unlimited number of classes of shares. Each
class of shares is equal as to earnings, assets and voting privileges, except as
noted above, and each class bears the expenses related to the distribution of
its shares. There are no conversion, preemptive or other subscription rights,
except with respect to the conversion of Class B Shares and certain Class C
Shares into Class A Shares as described above. In the event of liquidation, each
of the shares of the Fund is entitled to its portion of all of the Fund's net
assets after all debt and expenses of the Fund have been paid. Since Class B
Shares and Class C Shares pay higher distribution expenses, the liquidation
proceeds to holders of Class B Shares and Class C Shares are likely to be lower
than to other shareholders.
    
 
  The Trust does not contemplate holding regular meetings of shareholders to
elect Trustees or otherwise. However, the holders of 10% or more of the
outstanding shares may by written request require a meeting to consider the
removal of Trustees by a vote of two-thirds of the shares then outstanding cast
in person or by proxy at such meeting. The Trust will assist such holders in
communicating with other shareholders of the Fund to the extent required by the
1940 Act. More detailed information concerning the Trust is set forth in the
Statement of Additional Information.

- ------------------------------------------------------------------------------
 
    Van Kampen American Capital New Jersey Tax Free Income Fund (the "Fund") is
a non-diversified mutual fund, organized as a separate series of Van Kampen
American Capital Tax Free Trust. The Fund's investment objective is to provide
investors a high level of current income exempt from federal income tax and New
Jersey gross income tax, consistent with preservation of capital. The Fund is
designed for investors who are residents of New Jersey for tax purposes. Under
normal market conditions, the Fund seeks to achieve its investment objective by
investing at least 80% of its assets in a portfolio of New Jersey municipal
securities rated investment grade at the time of investment. Investment grade
securities are securities rated BBB or higher by Standard & Poor's Ratings Group
("S&P"), Baa or higher by Moody's Investors Service, Inc. ("Moody's") or an
equivalent rating by another nationally recognized statistical rating
organization ("NRSRO"). Up to 20% of the Fund's total assets may consist of New
Jersey municipal securities rated below investment grade (but not rated lower
than B- by S&P, B3 by Moody's or an equivalent rating by another NRSRO) and
unrated New Jersey municipal securities believed by the Fund's investment
adviser to be of comparable quality, which involve special risk considerations.
See "Municipal Securities." There is no assurance that the Fund will achieve its
investment objective.

                            PROPOSED REORGANIZATION
    
- ------------------------------------------------------------------------------
 
   
  On July 25, 1996, the Trustees of the Fund approved an Agreement and Plan of
reorganization between the Fund and Van Kampen American Capital Municipal Income
Fund (the "Municipal Fund"), also a series of the Tax Free Trust and advised by
Van Kampen American Capital Investment Advisory Corp., providing for the
transfer of assets and liabilities of the Fund to the Municipal Fund in exchange
for shares of beneficial interest of the Municipal Fund at its net asset value
per share (the "Reorganization").
    
 
   
  The Reorganization is subject to approval by the holders of a majority of the
outstanding shares of the Fund. Further details of the proposed Reorganization
will be contained in the proxy statement/prospectus expected to be mailed to
shareholders in 1997.
    
 
   
  The Municipal Fund's net assets as of December 31, 1996 were approximately
$1.02 billion. Its objective is to provide investors with a high level of
current income exempt from federal income tax, consistent with preservation of
capital. The investment objective of the Fund is to provide investors a high
level of current income exempt from federal income tax and New Jersey gross
income tax, consistent with preservation of capital. The primary difference
between the two investment objectives is that the Fund seeks income exempt from
New Jersey state income tax, but the Municipal Fund does not. The Trustees,
however, believe that the benefits to the Fund shareholders from the
Reorganization, including the potentially lower operating costs and potentially
higher yield from the Municipal Fund relative to the Fund, more than offset the
loss of the exemption from New Jersey state income tax.
    
 
   
  The Fund will continue its normal operations prior to the Reorganization.

                               PROSPECTUS SUMMARY
- ------------------------------------------------------------------------------
 
THE FUND.  Van Kampen American Capital New Jersey Tax Free Income Fund (the
"Fund") is a non-diversified mutual fund, organized as a separate series of Van
Kampen American Capital Tax Free Trust. See "The Fund."
 
INVESTMENT OBJECTIVE.  The Fund's investment objective is to provide investors a
high level of current income exempt from federal income tax and New Jersey gross
income tax, consistent with preservation of capital. The Fund is designed for
investors who are residents of New Jersey for tax purposes.
 
INVESTMENT POLICIES.  Under normal market conditions, the Fund seeks to achieve
its investment objective by investing at least 80% of its assets in a portfolio
of New Jersey municipal securities rated investment grade at the time of
investment. Investment grade securities are securities rated BBB or higher by
Standard & Poor's Ratings Group ("S&P"), Baa or higher by Moody's Investors
Service, Inc. ("Moody's") or an equivalent rating by another nationally
recognized statistical rating organization ("NRSRO"). Up to 20% of the Fund's
total assets may consist of New Jersey municipal securities rated below
investment grade (but not rated lower than B- by S&P, B3 by Moody's or an
equivalent rating by another NRSRO) and unrated New Jersey municipal securities
that the Fund's investment adviser believes are of comparable quality, which
involve special risk considerations. Up to 20% of the Fund's assets may be
invested in municipal securities that are subject to federal alternative minimum
tax. See "Investment Objective and Policies," "Municipal Securities" and
"Special Considerations Regarding the Fund."
 
INVESTMENT RESULTS.  The investment results of the Fund are shown in the table
of "Financial Highlights."
 
PURCHASE OF SHARES.  Shares of the Fund are offered through Van Kampen American
Capital Distributors, Inc. (the "Distributor"), as principal underwriter, and
through selected brokers and dealers. The offering price is the net asset value
per share next determined followed receipt of an order plus a sales charge
which, at the option of the investor, may be imposed at the time of purchase or
on a contingent deferred basis. Investors may elect to purchase Class A Shares,
Class B Shares or Class C Shares, each with different sales charges and
expenses. The minimum initial investment is $500 for each class of shares and
the minimum subsequent investment is $25 for each class of shares (or less as
described under "Purchase of Shares"). The different classes of shares permit an
investor to choose the method of purchasing shares that is more beneficial to
the investor, taking into account the amount of the purchase, the length of time
the investor expects to hold the shares and other circumstances. See "Purchase
of Shares."
 
   
INVESTMENT ADVISER.  Van Kampen American Capital Investment Advisory Corp. (the
"Adviser") is the Fund's investment adviser.
    
 
                                        4
<PAGE>   306
 
SPECIAL RISK FACTORS.  Up to 20% of the Fund's assets may consist of New Jersey
municipal securities rated below investment grade (but not rated lower than B-
by S&P, B3 by Moody's or an equivalent rating by another NRSRO) and in unrated
New Jersey municipal securities considered by the Adviser to be of comparable
quality. In addition, the Fund may invest up to 20% of its assets in certain
derivative securities such as inverse floaters. Investment in such lower grade
municipal securities and derivative securities involves significant risks.
Furthermore, under normal market conditions, the Fund will invest substantially
all of its assets in New Jersey municipal securities, and therefore it will be
more susceptible to factors adversely affecting issuers of New Jersey municipal
securities than a municipal securities fund that does not invest in New Jersey
municipal securities to this degree. There can be no assurance that the Fund
will achieve its objective. See "Special Considerations Regarding the Fund."
 
   
  The foregoing is qualified in its entirety by reference to the more detailed
    
              information appearing elsewhere in this Prospectus.

(1) Expenses include a waiver of $97,956 of "Management Fees" and assumption of
    $152,228 of "Other Expenses" and "12b-1 Fees" by the Adviser. If the Adviser
    did not waive fees for the fiscal year ending December 31, 1996, the
    "Management Fees" would have been 0.60% for each class of shares, "12b-1
    Fees" would have been 0.25% for Class A Shares and 1.00% each for Class B
    Shares and Class C Shares, "Other Expenses" would have been 1.06% for each
    class of shares and "Total Expenses" would have been 1.91% for Class A
    Shares, 2.66% for Class B Shares and 2.66% for Class C Shares.
    
 
   
(2) Includes a service fee of up to 0.25% (as a percentage of net asset value)
    paid by the Fund as compensation for ongoing services rendered to investors.
    With respect to each class of shares, amounts in excess of 0.25%, if any,
    represent an asset based sales charge. The asset based sales charge with
    respect to Class C Shares includes 0.75% (as a percentage of net asset
    value) paid to investors' broker-dealers as sales compensation.

  The purpose of the foregoing table is to assist an investor in understanding
the various costs and expenses that an investor in the Fund will bear directly
or indirectly. The "Example" reflects expenses based on the "Annual Fund
Operating Expenses" table as shown above carried out to future years. As Fund
assets increase, the fees waived or expenses reimbursed by the Adviser are
expected to decrease. Accordingly, it is unlikely that future expenses as
projected will remain consistent with those determined based on the "Annual Fund
Operating Expenses" table. The ten year amounts with respect to Class B Shares
of the Fund reflects the lower aggregate 12b-1 and service fees applicable to
such shares after conversion to Class A Shares. THE INFORMATION CONTAINED IN THE
ABOVE TABLE SHOULD NOT BE CONSIDERED A REPRESENTATION OF PAST OR FUTURE EXPENSES
AND ACTUAL EXPENSES MAY BE GREATER OR LESSER THAN THOSE SHOWN. For a more
complete description of such costs and expenses, see "Purchase of Shares,"
"Redemption of Shares," "Investment Advisory Services" and "Distribution and
Service Plans."

THE FUND
- ------------------------------------------------------------------------------
 
  Van Kampen American Capital New Jersey Tax Free Income Fund (the "Fund") is a
non-diversified separate series of Van Kampen American Capital Tax Free Trust
(the "Trust"), an open-end management investment company, commonly known as a
"mutual fund," organized as a Delaware business trust. Mutual funds sell their
shares to investors and invest the proceeds in a portfolio of securities. A
mutual fund allows investors to pool their money with that of other investors in
order to obtain professional investment management. Mutual funds generally make
it possible for investors to obtain greater diversification of their investments
and to simplify their recordkeeping.
 
  Van Kampen American Capital Investment Advisory Corp. (the "Adviser") provides
investment advisory and administrative services to the Fund. The Adviser and its
affiliates also act as investment adviser to other mutual funds distributed by
Van Kampen American Capital Distributors, Inc. (the "Distributor"). To obtain
prospectuses and other information on any of these other funds, please call the
telephone number on the cover page of the Prospectus.
 
- ------------------------------------------------------------------------------
INVESTMENT OBJECTIVE AND POLICIES
- ------------------------------------------------------------------------------
 
  The investment objective of the Fund is to provide investors a high level of
current income exempt from federal income tax and New Jersey gross income tax,
consistent with preservation of capital. The Fund's investment objective is a
fundamental policy and may not be changed without shareholder approval of the
holders of a majority of the Fund's outstanding voting securities, as defined in
the Investment Company Act of 1940, as amended (the "1940 Act"). The Fund is
designed for investors who are residents of New Jersey for tax purposes. An
investment in the Fund may not be appropriate for all investors. The Fund is not
intended to be a complete investment program, and investors should consider
their long-term investment goals and financial needs when making an investment
decision with respect to the Fund. An investment in the Fund is intended to be a
long-term investment and should not be used as a trading vehicle.
 
  Under normal market conditions, the Fund will invest at least 80% of its total
assets in New Jersey municipal securities rated investment grade at the time of
investment. Investment grade securities are securities rated BBB or higher by
Standard & Poor's Ratings Group ("S&P"), Baa or higher by Moody's Investors
Service, Inc. ("Moody's") or an equivalent rating by another nationally
recognized statistical rating organization ("NRSRO") in the case of long-term
obligations, and have equivalent ratings in the case of short-term obligations.
According to published guidelines, securities rated BBB by S&P are regarded by
S&P as having an adequate capacity to pay interest and repay principal. Whereas
such securities normally exhibit adequate protection parameters, adverse
economic conditions or changing circumstances are more likely, in the opinion of
S&P, to lead to a
 
                                       10
<PAGE>   312
 
weakened capacity to pay interest and repay principal for debt in this category
than in higher rated categories. According to published guidelines, securities
rated Baa by Moody's are considered by Moody's as medium grade obligations. Such
securities are, in the opinion of Moody's, neither highly protected nor poorly
secured. Interest payments and principal security appear to Moody's to be
adequate for the present but certain protective elements may be lacking or may
be characteristically unreliable over any great length of time. In the opinion
of Moody's, they lack outstanding investment characteristics and in fact have
speculative characteristics as well. The Fund's policy with respect to ratings
is not a fundamental policy, and thus may be changed by the Trustees without
shareholder approval.
 
  Up to 20% of the Fund's total assets may be invested in New Jersey municipal
securities rated below investment grade (but not rated below B- by S&P, B3 by
Moody's or an equivalent rating by another NRSRO) and unrated New Jersey
municipal securities that the Adviser considers to be of comparable quality to
such securities. According to published guidelines, securities rated below
investment grade are regarded by S&P, on balance, as predominantly speculative
with respect to capacity to pay interest and repay principal in accordance with
the terms of the obligation. While in the opinion of S&P such securities will
likely have some quality and protective characteristics, these are outweighed by
large uncertainties or major risk exposures to adverse conditions. According to
published guidelines, securities rated below investment grade are regarded by
Moody's as generally lacking characteristics of a desirable investment.
Assurance of interest and principal payments or of maintenance of other terms of
the securities' contract over any long period of time may, in the opinion of
Moody's, be small. Debt securities rated below investment grade are commonly
referred to as "junk bonds." For a description of S&P's and Moody's ratings see
the Statement of Additional Information. From time to time the Fund temporarily
may also invest up to 10% of its assets in tax exempt money market funds. Such
instruments will be treated as investments in municipal securities.
 
  The Adviser will buy and sell securities for the Fund's portfolio with a view
to seeking a high level of current income exempt from federal income tax and New
Jersey gross income tax and will select securities which the Adviser believes
entail reasonable credit risk considered in relation to the investment policies
of the Fund. As a result, the Fund will not necessarily invest in the highest
yielding New Jersey municipal securities permitted by its investment policies if
the Adviser determines that market risks or credit risks associated with such
investments would subject the Fund's portfolio to undue risk. The potential for
realization of capital gains resulting from possible changes in interest rates
will not be a major consideration. Other than for tax purposes, frequency of
portfolio turnover generally will not be a limiting factor if the Fund considers
it advantageous to purchase or sell securities. The Fund anticipates that its
annual portfolio turnover rate normally will be less than 200%. A high rate of
portfolio turnover involves correspondingly greater brokerage commission
expenses or dealer costs than a lower rate, which expenses and costs must be
borne by the Fund and its shareholders. High portfolio turnover may also result
in
 
                                       11
<PAGE>   313
 
the realization of substantial net short-term capital gains and any
distributions resulting from such gains will be taxable. See "Tax Status" in
this Prospectus and "Investment Policies and Restrictions" in the Statement of
Additional Information.
 
  At times, conditions in the markets for New Jersey municipal securities may,
in the Adviser's judgment, make pursuing the Fund's basic investment strategy
inconsistent with the best interests of its shareholders. At such times, the
Adviser may use alternative strategies primarily designed to reduce fluctuations
in the value of the Fund's assets. In implementing these "defensive" strategies,
the Fund may invest to a substantial degree in high-quality, short-term New
Jersey municipal obligations. If these high-quality, short-term New Jersey
municipal obligations are not available or, in the Adviser's judgment, do not
afford sufficient protection against adverse market conditions, the Fund may
invest in high-quality municipal securities of issuers other than issuers of New
Jersey municipal securities. Furthermore, if such high-quality municipal
securities are not available or, in the Adviser's judgment do not afford
sufficient protection against adverse market conditions, the Fund may invest in
taxable obligations. Such taxable obligations may include: obligations of the
U.S. Government, its agencies or instrumentalities; other debt securities rated
within the four highest categories by either S&P or Moody's (or comparably rated
by another NRSRO); commercial paper rated in the highest grade by either rating
service (or comparably rated by another NRSRO); certificates of deposit and
bankers' acceptances; repurchase agreements with respect to any of the foregoing
investments; or any other fixed-income securities that the Adviser considers
consistent with such strategy. To the extent that the Fund invests a substantial
portion of its assets in municipal securities other than New Jersey municipal
securities or in taxable securities for temporary defensive purposes, the Fund
will not be invested in a manner primarily designed to achieve a high level of
current income exempt from federal income tax and New Jersey gross income tax.
In addition, under New Jersey tax law, to qualify as a "qualified investment
fund", at the close of each quarter the Fund must have not less than 80% of the
aggregate principal amount of all of its investments, excluding certain
investments, in New Jersey municipal securities, or any other obligations the
interest or gains on which is exempt from New Jersey gross income tax. See "Tax
Status -- New Jersey Taxation."

MUNICIPAL SECURITIES
- ------------------------------------------------------------------------------
 
  GENERAL. Municipal securities are obligations issued by or on behalf of
states, territories or possessions of the United States, the District of
Columbia and their political subdivisions, agencies and instrumentalities, the
interest on which, in the opinion of bond counsel or other counsel to the issuer
of such securities is, at the time of issuance, exempt from federal income tax.
New Jersey municipal securities are municipal securities the interest on which,
in the opinion of bond counsel or other counsel to the issuers of such
securities, is at the time of issuance exempt from New Jersey gross income tax.
If it is determined that the interest on municipal
 
                                       12
<PAGE>   314
 
securities is includable in gross income for federal income tax purposes or the
interest on New Jersey municipal securities is not exempt from New Jersey gross
income tax, the Fund may not qualify as a "qualified investment fund" under New
Jersey tax law. See "Tax Status -- New Jersey Taxation." Under normal market
conditions, at least 80% of the Fund's assets will be invested in New Jersey
municipal securities. The policy stated in the foregoing sentence is a
fundamental policy of the Fund and cannot be changed without approval of the
shareholders of the Fund. Up to 20% of the Fund's assets may be invested in
municipal securities that are subject to federal alternative minimum tax.
 
  The two principal classifications of municipal securities are "general
obligation" and "revenue" securities. "General obligation" securities are
secured by the issuer's pledge of its faith, credit and taxing power for the
payment of principal and interest. "Revenue" securities are usually payable only
from the revenues derived from a particular facility or class of facilities or,
in some cases, from the proceeds of a special excise tax or other specific
revenue source. Industrial development bonds are usually revenue securities, the
credit quality of which is normally directly related to the credit standing of
the industrial user involved.
 
  Within these principal classifications of municipal securities, there are a
variety of types of municipal securities, including fixed and variable rate
securities, municipal notes, municipal leases, custodial receipts, participation
certificates and derivative municipal securities the terms of which include
elements of, or are similar in effect to, certain Strategic Transactions (as
defined below) in which the Fund may engage. Variable rate securities bear rates
of interest that are adjusted periodically according to formulae intended to
reflect market rates of interest. The Fund may also invest in derivative
variable rate securities such as inverse floaters whose rates vary inversely
with changes in market rates of interest. When market rates of interest
decrease, the change in value of such securities will have a positive effect on
the net asset value of the Fund and when market rates of interest increase, the
change in value of such securities will have a negative effect on the net asset
value of the Fund. The extent of increases and decreases in the value of inverse
floaters and the corresponding change to the net asset value of the Fund
generally will be larger than comparable changes in the value of an equal
principal amount of a fixed rate municipal security having similar credit
quality, redemption provisions and maturity. The Fund will not invest more than
20% of its total assets in securities whose rates vary inversely with changes in
market rates of interest.
 
  Municipal notes include tax, revenue and bond anticipation notes of short
maturity, generally less than three years, which are issued to obtain temporary
funds for various public purposes. Municipal leases are obligations issued by
state and local governments or authorities to finance the acquisition of
equipment and facilities. Certain municipal lease obligations may include
"non-appropriation" clauses which provide that the municipality has no
obligation to make lease or installment purchase payments in future years unless
money is appropriated for such purpose on a yearly basis. Custodial receipts are
underwritten by securities
 
                                       13
<PAGE>   315
 
dealers or banks and evidence ownership of future interest payments, principal
payments or both on certain municipal securities. Participation certificates are
obligations issued by state or local governments or authorities to finance the
acquisition of equipment and facilities. They may represent participations in a
lease, an installment purchase contract, or a conditional sales contract.
Municipal securities may not be backed by the faith, credit and taxing power of
the issuer. Other than as set forth above, there is no limitation with respect
to the amount of the Fund's assets that may be invested in the foregoing types
of municipal securities. Certain of the municipal securities in which the Fund
may invest represent relatively recent innovations in the municipal securities
markets and the markets for such securities may be less developed than the
market for conventional fixed rate municipal securities. A more detailed
description of the types of municipal securities in which the Fund may invest is
included in the Statement of Additional Information.
 
  Under normal market conditions, longer term municipal securities generally
provide a higher yield than shorter term municipal securities, and therefore the
Fund generally expects to invest primarily in longer term municipal securities.
The Fund will, however, invest in shorter term municipal securities when it
believes market conditions warrant such investments. The net asset value of the
Fund will change with changes in the value of its portfolio securities. Because
the Fund will invest primarily in fixed income municipal securities, the net
asset value of the Fund can be expected to change as general levels of interest
rates fluctuate. When interest rates decline, the value of a portfolio invested
in fixed income securities generally can be expected to rise. Conversely, when
interest rates rise, the value of a portfolio invested in fixed income
securities generally can be expected to decline. The prices of longer term
municipal securities generally are more volatile with respect to changes in
interest rates than the prices of shorter term municipal securities. Volatility
may be greater during periods of general economic uncertainty.
 
  Although at least 80% of the municipal securities in which the Fund may invest
will be rated investment grade at the time of investment, municipal securities,
like other debt obligations, are subject to the risk of non-payment. The ability
of issuers of municipal securities to make timely payments of interest and
principal may be adversely impacted in general economic downturns and as
relative governmental cost burdens are allocated and reallocated among federal,
state and local governmental units. Such non-payment would result in a reduction
of income to the Fund, and could result in a reduction in the value of the
municipal securities experiencing non-payment and a potential decrease in the
net asset value of the Fund.
 
  Up to 20% of the Fund's assets may be invested in municipal securities that
are subject to federal alternative minimum tax. The Fund may not be a suitable
investment for investors who are already subject to the federal alternative
minimum tax or who would become subject to the federal alternative minimum tax
as a result of an investment in the Fund. In addition, income earned or deemed
to be earned
 
                                       14
<PAGE>   316
 
with respect to the Fund's Strategic Transactions, if any, will be taxable. See
"Tax Status."
 
  From time to time, proposals have been introduced before Congress that would
have the effect of reducing or eliminating the federal tax exemption on
municipal securities. If such a proposal were enacted, the ability of the Fund
to pay tax exempt interest dividends might be adversely affected.
 
  LOWER GRADE MUNICIPAL SECURITIES. The Fund may invest up to 20% of its total
assets in New Jersey municipal securities rated below investment grade (but not
rated lower than B- by S&P, B3 by Moody's or an equivalent rating by another
NRSRO) or in unrated municipal securities considered by the Adviser to be of
comparable quality to such securities. Higher yields are generally available
from municipal securities of such grade. With respect to such 20% of the Fund's
total assets, the Fund has not established any limit on the percentage of its
portfolio which may be invested in securities in any one rating category or
comparable unrated securities.
 
  Investors should carefully consider the risks of owning shares of an
investment company which invests in lower grade municipal securities before
making an investment in the Fund. The higher yield on certain securities held by
the Fund reflects a greater possibility that the financial condition of the
issuer, or adverse changes in general economic conditions, or both, may impair
the ability of the issuer to make payments of income and principal. See "Special
Considerations Regarding the Fund."
 
  The Adviser seeks to minimize the risks involved in investing in lower grade
municipal securities through diversification and careful investment analysis. To
the extent that there is no established retail market for some of the lower
grade municipal securities in which the Fund may invest, trading in such
securities may be relatively inactive. The Adviser is responsible for
determining the net asset value of the Fund, subject to the supervision of the
Board of Trustees of the Trust. During periods of reduced market liquidity and
in the absence of readily available market quotations for lower grade municipal
securities held in the Fund's portfolio, the ability of the Adviser to value the
Fund's securities becomes more difficult and the Adviser's use of judgment may
play a greater role in the valuation of the Fund's securities due to the reduced
availability of reliable objective data. The effects of adverse publicity and
investor perceptions may be more pronounced for securities for which no
established retail market exists as compared with the effects on securities for
which such a market does exist. Further, the Fund may have more difficulty
selling such securities in a timely manner and at their stated value than would
be the case for securities for which an established retail market does exist.
See "Special Considerations Regarding the Fund."

INVESTMENT PRACTICES
- ------------------------------------------------------------------------------
 
  In connection with the investment policies described above, the Fund also may
engage in strategic transactions and purchase and sell securities on a "when
issued" and "delayed delivery" basis. These investments entail risks. Strategic
transactions generally will not be treated as investments in New Jersey
municipal securities for purposes of the Fund's 80% investment policy with
respect thereto.
 
  STRATEGIC TRANSACTIONS. The Fund may purchase and sell derivative instruments
such as exchange-listed and over-the-counter put and call options on securities,
financial futures, fixed-income indices and other financial instruments,
purchase and sell financial futures contracts and enter into various interest
rate transactions such as swaps, caps, floors or collars. Collectively, all of
the above are referred to as "Strategic Transactions." Under current New Jersey
tax law, the Fund may purchase and sell exchange listed and over-the-counter put
and call options and purchase and sell financial futures. See "Tax Status -- New
Jersey Taxation." The Fund also reserves the right to engage in swaps, caps,
floors or collars. However, current New Jersey tax law may limit the Fund's
ability to enter into such transactions. Strategic Transactions may be used to
attempt to protect against possible changes in the market value of securities
held in or to be purchased for the Fund's portfolio resulting from securities
markets, to protect the Fund's unrealized gains in the value of its portfolio
securities, to facilitate the sale of such securities for investment purposes,
to manage the effective maturity or duration of the Fund's portfolio, or to
establish a position in the derivatives markets as a temporary substitute for
purchasing or selling particular securities. Any or all of these investment
techniques may be used at any time and there is no particular strategy that
dictates the use of one technique rather than another, as use of any Strategic
Transaction is a function of numerous variables including market conditions. The
ability of the Fund to utilize these Strategic Transactions successfully will
depend on the Adviser's ability to predict pertinent market movements, which
cannot be assured. The Fund will comply with applicable regulatory requirements
when implementing these strategies, techniques and instruments.
 
  Strategic Transactions have risks associated with them including possible
default by the other party to the transaction, illiquidity and, to the extent
the Adviser's view as to certain market movements is incorrect, the risk that
the use of such Strategic Transactions could result in losses greater than if
they had not been used. Use of put and call options may result in losses to the
Fund, force the sale of portfolio securities at inopportune times or for prices
other than at current market values, limit the amount of appreciation the Fund
can realize on its investments or cause the Fund to hold a security it might
otherwise sell. The use of options and futures transactions entails certain
other risks. In particular, the variable degree of correlation between price
movements of futures contracts and price movements in the related portfolio
position of the Fund creates the possibility that losses on the hedging
instrument may be greater than gains in the value of the Fund's position. In
 
                                       16
<PAGE>   318
 
addition, futures and options markets may not be liquid in all circumstances and
certain over-the-counter options may have no markets. As a result, in certain
markets, the Fund might not be able to close out a transaction without incurring
substantial losses, if at all. Although the contemplated use of these futures
contracts and options thereon should tend to minimize the risk of loss due to a
decline in the value of the hedged position, at the same time they tend to limit
any potential gain which might result from an increase in value of such
position. Finally, the daily variation margin requirements for futures contracts
would create a greater ongoing potential financial risk than would purchases of
options, where the exposure is limited to the cost of the initial premium.
Losses resulting from the use of Strategic Transactions would reduce net asset
value, and possibly income, and such losses can be greater than if the Strategic
Transactions had not been utilized. The Strategic Transactions that the Fund may
use and some of their risks are described more fully in the Fund's Statement of
Additional Information.
 
  Income earned or deemed to be earned by the Fund from, among other things, its
Strategic Transactions and temporary defensive strategies, if any, will
generally be taxable income of the Fund. See "Tax Status."
 
   
  "WHEN ISSUED" AND "DELAYED DELIVERY" TRANSACTIONS. The Fund may also purchase
and sell municipal securities on a "when issued" and "delayed delivery" basis.
No income accrues to the Fund on municipal securities in connection with such
purchase transactions prior to the date the Fund actually takes delivery of such
securities. These transactions are subject to market fluctuation; the value of
the municipal securities at delivery may be more or less than their purchase
price, and yields generally available on municipal securities when delivery
occurs may be higher or lower than yields on the municipal securities obtained
pursuant to such transactions. Because the Fund relies on the buyer or seller,
as the case may be, to consummate the transaction, failure by the other party to
complete the transaction may result in the Fund missing the opportunity of
obtaining a price or yield considered to be advantageous. When the Fund is the
buyer in such a transaction, however, it will maintain, in a segregated account
with its custodian, cash or liquid securities having an aggregate value equal to
the amount of such purchase commitments until payment is made. The Fund will
make commitments to purchase municipal securities on such basis only with the
intention of actually acquiring these securities, but the Fund may sell such
securities prior to the settlement date if such sale is considered to be
advisable. To the extent the Fund engages in "when issued" and "delayed
delivery" transactions, it will do so for the purpose of acquiring securities
for the Fund's portfolio consistent with the Fund's investment objectives and
policies and not for the purposes of investment leverage. No specific limitation
exists as to the percentage of the Fund's assets which may be used to acquire
securities on a "when issued" or "delayed delivery" basis.
    
 
  RESTRICTED AND ILLIQUID SECURITIES. The Fund may invest up to 15% of its net
assets in illiquid securities including securities the disposition of which is
subject to substantial legal or contractual restrictions on resale and
securities that are not
 
                                       17
<PAGE>   319
 
readily marketable. The sale of restricted and illiquid securities often
requires more time and results in higher brokerage charges or dealer discounts
and other selling expenses than does the sale of securities eligible for trading
on national securities exchanges or in the over-the-counter markets. Restricted
securities may sell at a price lower than similar securities that are not
subject to restrictions on resale.
 
  OTHER PRACTICES. The Fund may borrow amounts up to 5% of its net assets in
order to pay for redemptions when liquidation of portfolio securities is
considered disadvantageous or inconvenient and may pledge up to 10% of its net
assets to secure such borrowings.
 
  Under normal market conditions, the fund will invest substantially all of its
assets in New Jersey municipal securities. The Fund generally will not invest
more than 25% of its total assets in any industry. Governmental issuers of
municipal securities are not considered part of any "industry." However,
municipal securities backed only by the assets and revenues of nongovernmental
users may for this purpose be deemed to be issued by such nongovernmental users,
and the 25% limitation would apply to such obligations. It is therefore possible
that the Fund may invest more than 25% of its assets in a broader segment of the
municipal securities market, such as revenue obligations of hospitals and other
health care facilities, housing agency revenue obligations, or airport revenue
obligations if the Adviser determines that the yields available from obligations
in a particular segment of the market justifies the additional risks associated
with a large investment in such segment. Although such obligations could be
supported by the credit of governmental users, or by the credit of
nongovernmental users engaged in a number of industries, economic, business,
political and other developments generally affecting the revenues of such users
(for example, proposed legislation or pending court decisions affecting the
financing of such projects and market factors affecting the demand for their
services or products) may have a general adverse effect on all municipal
securities in such a market segment.
 
  From time to time, the Fund's investments may include securities as to which
the Fund, by itself or together with other funds or accounts managed by the
Adviser, holds a major portion or all of an issue of New Jersey municipal
securities. Because there may be relatively few potential purchasers for such
investments and, in some cases, there may be contractual restrictions on
resales, the Fund may find it more difficult to sell such securities at a time
when the Adviser believes it is advisable to do so.
 
  INVESTMENT RESTRICTIONS. The Fund is subject to certain investment
restrictions which constitute fundamental policies. Fundamental policies cannot
be changed without the approval of the holders of a majority of the Fund's
outstanding voting securities, as defined in the 1940 Act. See "Investment
Policies and Restrictions" in the Statement of Additional Information.
 
                                       18
<PAGE>   320
 
  PORTFOLIO TRANSACTIONS AND BROKERAGE ALLOCATION. 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 prices and any
brokerage commissions. The income securities in which the Fund invests are
traded principally in the over-the-counter market. In the over-the-counter
market, securities are generally traded on a net basis with dealers acting as
principal for their own accounts without a stated commission, although the price
of the security usually includes a mark-up to the dealer. Securities purchased
in underwritten offerings generally include, in the price, a fixed amount of
compensation for the managers, underwriters and dealers. The Fund may also
purchase certain money market instruments directly from an issuer, in which case
no commissions or discounts are paid. Purchases and sales of bonds on a stock
exchange are effected through brokers who charge a commission for their
services.
 
  The Adviser is responsible for effecting securities transactions of the Fund
and will do so in a manner deemed fair and reasonable to shareholders of the
Fund and not according to any formula. The Adviser's primary considerations in
selecting the manner of executing securities transactions for the Fund will be
prompt execution of orders, the size and breadth of the market for the security,
the reliability, integrity and financial condition and execution capability of
the firm, the size of and difficulty in executing the order, and the best net
price. There are many instances when, in the judgment of the Adviser, more than
one firm can offer comparable execution services. In selecting among such firms,
consideration is given to those firms which supply research and other services
in addition to execution services. However, it is not the policy of the Adviser,
absent special circumstances, to pay higher commissions to a firm because it has
supplied such services.
 
  In effecting purchases and sales of the Fund's portfolio securities, the
Adviser and the Fund may place orders with and pay brokerage commissions to
brokers, including brokers which may be affiliated with the Fund, the Adviser
and the Distributor or dealers participating in the offering of the Fund's
shares. In addition, in selecting among firms to handle a particular
transaction, the Adviser and the Fund may take into account whether the firm has
sold or is selling shares of the Fund. See "Portfolio Transactions and Brokerage
Allocation" in the Statement of Additional Information for more information.
 
- ------------------------------------------------------------------------------
SPECIAL CONSIDERATIONS REGARDING THE FUND
- ------------------------------------------------------------------------------
 
  GENERAL. In normal circumstances, the Fund may invest up to 20% of its total
assets in New Jersey municipal securities rated below investment grade (but not
lower than B- by S&P, B3 by Moody's or an equivalent rating by another NRSRO) or
in unrated New Jersey municipal securities considered by the Adviser to be of
comparable quality to such securities. Investment in such lower grade municipal
securities involves special risks as compared with investment in higher grade
municipal securities. The market for lower grade municipal securities is
 
                                       19
<PAGE>   321
 
considered to be less liquid than the market for investment grade municipal
securities which may adversely affect the ability of the Fund to dispose of such
securities in a timely manner at a price which reflects the value of such
security in the Adviser's judgement. The market price for less liquid securities
tends to be more volatile than the market price for more liquid securities.
Illiquid securities and the absence of readily available market quotations with
respect thereto may make the Adviser's valuation of such securities more
difficult, and the Adviser's judgment may play a greater role in the valuation
of the Fund's securities. Lower grade municipal securities generally involve
greater credit risk than higher grade municipal securities and are more
sensitive to adverse economic changes, significant increases in interest rates
and individual issuer developments. Because issuers of lower grade municipal
securities frequently choose not to seek a rating of their municipal securities,
the Fund will rely more heavily on the Adviser's ability to determine the
relative investment quality of such securities than if the Fund invested
exclusively in higher grade municipal securities. The Fund may, if deemed
appropriate by the Adviser, retain a security whose rating has been downgraded
below B- by S&P, below B3 by Moody's or an equivalent rating by another NRSRO,
or whose rating has been withdrawn. More detailed information concerning the
risks associated with instruments in lower grade municipal securities is
included in the Fund's Statement of Additional Information.
 
  The Fund may invest up to 20% of its total assets in derivative variable rate
securities such as inverse floaters whose rates of interest vary inversely with
changes in market rates of interest. When market rates of interest decrease, the
change in value of such securities will have a positive effect on the net asset
value of the Fund and when market rates of interest increase, the change in
value of such securities will have a negative effect on the net asset value of
the Fund. Investment in such securities involve special risks as compared to a
fixed rate municipal security. The extent of increases and decreases in the
value of inverse floaters and the corresponding change to per share net asset
value of the Fund generally will be larger than comparable changes in the value
of an equal principal amount of a fixed rate municipal security having similar
credit quality, redemption provisions and maturity. The markets for inverse
variable rate securities may be less developed than the market for conventional
fixed rate municipal securities.
 
  SPECIAL CONSIDERATIONS REGARDING NEW JERSEY MUNICIPAL SECURITIES. Investors
should be aware of certain factors that might affect the financial condition of
the issuers of New Jersey municipal securities. New Jersey's economic base is
diversified, consisting of a variety of manufacturing, construction and service
industries, supplemented by rural areas with selective commercial agriculture.
By the beginning of the national recession in 1990, construction activity had
already been declining in New Jersey for nearly two years. The onset of
recession caused an acceleration of New Jersey's job losses in construction and
manufacturing, as well as an employment downturn in such previously growing
sectors as wholesale trade, retail trade, finance, utilities and trucking and
warehousing. Reflecting the downturn, the rate of unemployment in the State rose
from a peacetime low of 3.6%
 
                                       20
<PAGE>   322
 
   
during the first quarter of 1989 to a recessionary peak of 8.5% during 1992.
Since then, the unemployment rate fell to an average of 6.4% in 1995 and 6.1%
for the four month period from May 1996 through August 1996.
    
 
  New Jersey operates under an annual budget which is formulated and submitted
for legislative approval by the Governor by the third Tuesday following the
first meeting of the State Legislature in each year. After a process of
legislative committee review, the budget, in the form of an appropriations bill,
must be approved by the Senate and Assembly and must be approved and signed by
the Governor before any expenditure may be made in a fiscal year. At the time of
signing the bill, the Governor may revise the estimate of anticipated revenues
and may delete or reduce appropriation items contained in the bill. Like any
gubernatorial veto, that action may be reversed by a two-thirds vote of each
House of the New Jersey Legislature. In addition to anticipated revenues, the
appropriations act also provides for the appropriation of non-budgeted revenue
to the extent such revenue may be received and permits the corresponding
increase of appropriation balances from which expenditures may be made. New
Jersey operates on a fiscal year beginning July 1 and ending June 30.
 
   
  On July 3, 1991, S&P downgraded New Jersey general obligation bonds to "AA+."
On August 26, 1992, Moody's downgraded New Jersey general obligation bonds to
"Aa1." The issuance of the $526,800,000 State of New Jersey General Obligation
Bonds, Refunding Bonds (Series E) and $270,000,000 State of New Jersey General
Obligation Bonds (Various Purposes), on May 1, 1996, was rated AA+ by S&P and
Aa1 by Moody's. Local municipalities issuing New Jersey municipal securities,
although impacted in general by the economic condition of the State, have credit
ratings that are determined with reference to the economic condition of such
local municipalities.
    
 
  Although revenue obligations of the State of New Jersey or its political
subdivisions may be payable from a specific project or source, including lease
rentals, there can be no assurance that future economic difficulties and the
resulting impact on State and local government finances will not adversely
affect the market value of the portfolio of the Fund or the ability of the
respective obligors to make timely payments of principal and interest on such
obligations.
 
  More detailed information concerning New Jersey municipal securities and the
State of New Jersey is included in the Statement of Additional Information.

Ethics designed to recognize the fiduciary relationship between the Fund and the
Adviser and its employees. The Codes permit directors, trustees, officers and
employees to buy and sell securities for their personal accounts subject to
certain restrictions. Persons with access to certain sensitive information are
subject to preclearance and other procedures designed to prevent conflicts of
interest.
    
 
  PORTFOLIO MANAGEMENT. David C. Johnson, a Senior Vice President of the
Adviser, supervises the Adviser's municipal securities practice area and
coordinates the Adviser's investment policy regarding such securities. Mr.
Johnson has been employed by the Adviser since April 1989. Timothy D. Haney,
Assistant Vice President and municipal portfolio manager of the Adviser, has
been primarily responsible for the day-to-day management of the Fund's portfolio
since August 1995. From 1992 to 1995 Mr. Haney was employed by the Distributor
as a unit trust bond buyer. Prior to 1992, Mr. Haney was employed by the Adviser
as a municipal analyst.
 
- ------------------------------------------------------------------------------
ALTERNATIVE SALES ARRANGEMENTS
- ------------------------------------------------------------------------------
 
  The Alternative Sales Arrangements permit an investor to choose the method of
purchasing shares that is more beneficial to the investor, taking into account
the amount of the purchase, the length of time the investor expects to hold the
shares, whether the investor wishes to receive dividends in cash or to reinvest
them in additional shares of the Fund, and other circumstances. Investors should
consider such factors together with the amount of sales charges and accumulated
distribution and service fees with respect to each class of shares that may be
incurred over the anticipated duration of their investment in the Fund.
 
                                       23
<PAGE>   325
 
  The Fund offers three classes of shares, designated Class A Shares, Class B
Shares and Class C Shares. Shares of each class are offered at a price equal to
their net asset value per share plus a sales charge which, at the election of
the purchaser, may be imposed (a) at the time of purchase ("Class A Shares") or
(b) on a contingent deferred basis (Class A Share accounts over $1 million,
"Class B Shares" and "Class C Shares"). Class A Share accounts over $1 million
or otherwise subject to a contingent deferred sales charge ("CDSC"), Class B
Shares and Class C Shares sometimes are referred to herein collectively as
"Contingent Deferred Sales Charge Shares" or "CDSC Shares."
 
  The minimum initial investment with respect to each class of shares is $500.
The minimum subsequent investment with respect to each class of shares is $25.
It is presently the policy of the Distributor not to accept any order for Class
B Shares in an amount of $500,000 or more and not to accept any order for Class
C Shares in an amount of $1 million or more because it ordinarily will be more
advantageous for an investor making such an investment to purchase Class A
Shares.
 
  An investor should carefully consider the sales charges applicable to each
class of shares and the estimated period of their investment to determine which
class of shares is more beneficial for the investor to purchase. For example,
investors who would qualify for a significant purchase price discount from the
maximum sales charge on Class A Shares may determine that payment of such a
reduced front-end sales charge is superior to electing to purchase Class B
Shares or Class C Shares, each with no front-end sales charge but subject to a
CDSC and a higher aggregate distribution and service fee. However, because
initial sales charges are deducted at the time of purchase of Class A Share
accounts under $1 million, a purchaser of such Class A Shares would not have all
of his or her funds invested initially and, therefore, would initially own fewer
shares than if Class B Shares or Class C Shares had been purchased. On the other
hand, an investor whose purchase would not qualify for price discounts
applicable to Class A Shares and intends to remain invested until after the
expiration of the applicable CDSC may wish to defer the sales charge and have
all his or her funds initially invested in Class B Shares or Class C Shares. If
such an investor anticipates that he or she will redeem such shares prior to the
expiration of the CDSC period applicable to Class B Shares, the investor may
wish to acquire Class C Shares. Investors must weigh the benefits of deferring
the sales charge and having all of their funds invested against the higher
aggregate distribution and service fee applicable to Class B Shares and Class C
Shares (discussed below).
 
  Each class of shares represents an interest in the same portfolio of
investments of the Fund and has the same rights, except each class of shares (i)
bears those distribution fees, service fees and administrative expenses
applicable to the respective class of shares as a result of its sales
arrangements, (ii) has exclusive voting rights with respect to those provisions
of the Fund's Rule 12b-1 distribution plan which relate only to such class and
(iii) has a different exchange privilege. Generally, a class of shares subject
to a higher ongoing distribution fee and service
 
                                       24
<PAGE>   326
 
fee or subject to the conversion feature have a higher expense ratio and pay
lower dividends than a class of shares subject to a lower ongoing distribution
and service fee or not subject to the conversion feature. The per share net
asset values of the different classes of shares are expected to be substantially
the same; from time to time, however, the per share net asset values of the
classes may differ. The net asset value per share of each class of shares of the
Fund will be determined as described in this Prospectus under "Purchase of
Shares -- Net Asset Value."
 
   
  The administrative expenses that may be allocated to a specific class of
shares may consist of (i) ACCESS' expenses attributable to a specific class of
shares, which expenses typically will be higher with respect to classes of
shares subject to the conversion feature; (ii) printing and postage expenses
related to preparing and distributing materials such as shareholder reports,
prospectuses and proxy statements to current shareholders of a specific class;
(iii) Securities and Exchange Commission (the "SEC") registration fees incurred
by a class of shares; (iv) the expense of administrative personnel and services
as required to support the shareholders of a specific class; (v) Trustees' fees
or expense incurred as a result of issues relating to one class of shares; (vi)
accounting expenses relating solely to one class of shares; and (vii) any other
incremental expenses subsequently identified that should be properly allocated
to one or more classes of shares. All such expenses incurred by a class will be
borne on a pro rata basis by the outstanding shares of such class. All
allocations of administrative expenses to a particular class of shares will be
limited to the extent necessary to preserve the Fund's qualification as a
regulated investment company under the Internal Revenue Code of 1986, as amended
(the "Code").
    
 
- ------------------------------------------------------------------------------
PURCHASE OF SHARES
- ------------------------------------------------------------------------------
 
   
  The Fund offers three classes of shares to the public on a continuous basis
through the Distributor, as principal underwriter, which is located at One
Parkview Plaza, Oakbrook Terrace, Illinois 60181. Shares also are offered
through members of the National Association of Securities Dealers, Inc. ("NASD")
acting as securities dealers ("dealers") and through NASD members acting as
brokers for investors ("brokers") or eligible non-NASD members acting as agents
for investors ("financial intermediaries"). The Fund reserves the right to
suspend or terminate the continuous public offering of its shares at any time
and without prior notice.
    
 
  The Fund's shares are offered at the net asset value per share next computed
after an investor places an order to purchase directly with the investor's
broker, dealer or financial intermediary or directly with the Distributor plus
any applicable sales charge. Sales personnel or brokers, dealers and financial
intermediaries distributing the Fund's shares may receive different compensation
for selling different classes of shares. It is the responsibility of the
investor's broker, dealer or financial intermediary to transmit the order to the
Distributor. Because the Fund generally will determine net asset value once each
business day as of the close of business,
 
                                       25
<PAGE>   327
 
purchase orders placed through an investor's broker, dealer or financial
intermediary must be transmitted to the Distributor by such broker, dealer or
financial intermediary prior to such time in order for the investor's order to
be fulfilled on the basis of the net asset value to be determined that day. Any
change in the purchase price due to the failure of the Distributor to receive a
purchase order prior to such time must be settled between the investor and the
broker, dealer or financial intermediary submitting the order.
 
   
  The Distributor may from time to time implement programs under which a broker,
dealer or financial intermediary's sales force may be eligible to win nominal
awards for certain sales efforts or under which the Distributor will reallow to
any broker, dealer or financial intermediary that sponsors sales contests or
recognition programs conforming to criteria established by the Distributor, or
participates in sales programs sponsored by the Distributor, an amount not
exceeding the total applicable sales charges on the sales generated by the
broker, dealer or financial intermediary at the public offering price during
such programs. Other programs provide, among other things and subject to certain
conditions, for certain favorable distribution arrangements for shares of the
Fund. Also, the Distributor in its discretion may from time to time, pursuant to
objective criteria established by it, pay fees to, and sponsor business seminars
for, qualifying brokers, dealers or financial intermediaries for certain
services or activities which are primarily intended to result in sales of shares
of the Fund. Fees may include payment for travel expenses, including lodging,
incurred in connection with trips taken by invited registered representatives
and members of their families to locations within or outside of the United
States for meetings or seminars of a business nature. In some instances
additional compensation or promotional incentives may be offered to brokers,
dealers or financial intermediaries that have sold or may sell significant
amounts of shares during specified periods of time. The Distributor may provide
additional compensation to Edward D. Jones & Co. or an affiliate thereof based
on a combination of its sales of shares and increases in assets under
management. Such payments to brokers, dealers and financial intermediaries for
sales contests, other sales programs and seminars are made by the Distributor
out of its own assets and not out of the assets of the Fund. Such fees paid for
such services and activities with respect to the Fund will not exceed in the
aggregate 1.25% of the average total daily net assets of the Fund on an annual
basis. These programs will not change the price an investor pays for shares or
the amount that the Fund will receive from such sale.
    
 
CLASS A SHARES
 
  The public offering price of Class A Shares is equal to the net asset value
per share plus an initial sales charge which is a variable percentage of the
offering price depending upon the amount of the sale. The table below shows
total sales charges and dealer concessions reallowed to dealers and agency
commissions paid to brokers with respect to sales of Class A Shares. The sales
charge is allocated between the investor's broker, dealer or financial
intermediary and the Distributor. As indicated
 
                                       26
<PAGE>   328
 
previously, at the discretion of the Distributor, the entire sales charge may be
reallowed to such broker, dealer or financial intermediary. The staff of the SEC
has taken the position that dealers who receive 90% or more of the sales charge
may be deemed to be "underwriters" as that term is defined in the Securities Act
of 1933, as amended.

* No sales charge is payable at the time of purchase on investments of $1
  million or more, although for such investments the Fund imposes a CDSC of
  1.00% on redemptions made within one year of the purchase. A commission
  will be paid to brokers, dealers or financial intermediaries who initiate
  and are responsible for purchases of $1 million or more as follows: 1.00%
  on sales to $2 million, plus 0.80% on the next $1 million and 0.50% on the
  excess over $3 million. See "Purchase of Shares -- Deferred Sales Charge
  Alternatives" for additional information with respect to CDSC.
    
 
QUANTITY DISCOUNTS
 
  Investors purchasing Class A Shares may, under certain circumstances, be
entitled to pay reduced sales charges. The circumstances under which such
investors may pay reduced sales charges are described below.
 
  Investors, or their brokers, dealers or financial intermediaries, must notify
the Fund whenever a quantity discount is applicable to purchases. Upon such
notification, an investor will receive the lowest applicable sales charge.
Quantity discounts may be modified or terminated at any time. For more
information about quantity discounts, investors should contact their broker,
dealer or financial intermediary or the Distributor.
 
   
  A person eligible for a reduced sales charge includes an individual, their
spouse and children under 21 years of age and any corporation, partnership, or
sole proprietorship which is 100% owned, either alone or in combination, by any
of the foregoing; a trustee or other fiduciary of a single trust estate or a
single fiduciary account; or a "company" as defined is section 2(a)(8) of the
1940 Act.
    
 
                                       27
<PAGE>   329
 
   
  As used herein, "Participating Funds" refers to all open-end investment
companies advised by the Adviser or Van Kampen American Capital Asset
Management, Inc. and distributed by the Distributor. Additional funds may be
added from time to time as determined by the Fund's Board of Trustees as
Participating Funds.
    
 
   
  VOLUME DISCOUNTS. The size of investment shown in the preceding sales charge
table applies to the total dollar amount being invested by any person at any one
time in Class A Shares of the Fund, or in any combination of shares of the Fund
and shares of other Participating Funds, although other Participating Funds may
have different sales charges.
    
 
   
  CUMULATIVE PURCHASE DISCOUNT. The size of investment shown in the preceding
sales charge table may also be determined by combining the amount being invested
in Class A Shares of the Fund with other shares of the Fund and shares of
Participating Funds plus the current offering price of all shares of the Fund
and other Participating Funds, which have been previously purchased and are
still owned.
    
 
   
  LETTER OF INTENT. A Letter of Intent provides an opportunity for an investor
to obtain a reduced sales charge by aggregating the amount being invested over a
13-month period to determine the sales charge as outlined in the preceding sales
charge table. The size of investment shown in the preceding table includes the
amount of intended purchases of Class A Shares of the Fund with other shares of
the Fund and shares of the Participating Funds plus the value of all shares of
the Fund and other Participating Funds previously purchased during such 13-month
period and still owned. An investor may elect to compute the 13-month period
starting up to 90 days before the date of execution of a Letter of Intent. Each
investment made during the period receives the reduced sales charge applicable
to the total amount of the investment goal. If trades not initially made under a
Letter of Intent subsequently qualify for a lower sales charge through the
90-day back-dating provision, an adjustment will be made at the expiration of
the Letter of Intent to give effect to the lower charge. If the goal is not
achieved within the 13-month period, the investor must pay the difference
between the sales charge applicable to the purchases made and the sales charges
previously paid. When an investor signs a Letter of Intent, shares equal to at
least 5% of the total purchase amount of the level selected will be restricted
from sale or redemption by the investor until the Letter of Intent is satisfied
or any additional sales charges have been paid; if the Letter of Intent is not
satisfied by the investor and any additional sales charges are not paid,
sufficient restricted shares will be redeemed by the Fund to pay such charges.
Additional information is contained in the application accompanying this
Prospectus.
    
 
OTHER PURCHASE PROGRAMS
 
   
  Purchasers of Class A Shares may be entitled to reduced initial sales charges
in connection with unit investment trust reinvestment programs and purchases by
    
 
                                       28
<PAGE>   330
 
registered representatives of selling firms or purchases by persons affiliated
with the Fund or the Distributor. The Fund reserves the right to modify or
terminate these arrangements at any time.
 
  UNIT INVESTMENT TRUST REINVESTMENT PROGRAMS. The Fund permits unitholders of
unit investment trusts to reinvest distributions from such trusts in Class A
Shares of the Fund at net asset value with no minimum initial or subsequent
investment requirement if the administrator of an investor's unit investment
trust program meets certain uniform criteria relating to cost savings by the
Fund and the Distributor. The total sales charge for all other investments made
from unit trust distributions will be 1.00% of the offering price (1.01% of net
asset value). Of this amount, the Distributor will pay to the broker, dealer or
financial intermediary, if any, through which such participation in the
qualifying program was initiated 0.50% of the offering price as a dealer
concession or agency commission. Persons desiring more information with respect
to this program, including the applicable terms and conditions thereof, should
contact their broker, dealer, financial intermediary or the Distributor.
 
   
  The administrator of such a unit investment trust must have an agreement with
the Distributor pursuant to which the administrator will (1) submit a single
bulk order and make payment with a single remittance for all investments in the
Fund during each distribution period by all investors who choose to invest in
the Fund through the program and (2) provide ACCESS with appropriate backup data
for each participating investor in a computerized format fully compatible with
ACCESS' processing system.
    
 
   
  As further requirements for obtaining these special benefits, the Fund also
requires that all dividends and other distributions by the Fund be reinvested in
additional shares without any systematic withdrawal program. There will be no
minimum for reinvestments from unit investment trusts. The Fund will send
account activity statements to such participants on a monthly basis only, even
if their investments are made more frequently. The Fund reserves the right to
modify or terminate this program at any time.
    
 
  NAV PURCHASE OPTIONS. Class A Shares of the Fund may be purchased at net asset
value, upon written assurance that the purchase is made for investment purposes
and that the shares will not be resold except through redemption by the Fund,
by:
 
   
  (1) Current or retired trustees or directors of funds advised by the Adviser
      or Van Kampen American Capital Asset Management, Inc. and such persons'
      families and their beneficial accounts.
    
 
   
  (2) Current or retired directors, officers and employees of Morgan Stanley
      Group Inc. and any of its subsidiaries, employees of an investment
      subadviser to any fund described in (1) above or an affiliate of such
      subadviser; and such persons' families and their beneficial accounts.
    
 
                                       29
<PAGE>   331
 
   
  (3) Directors, officers, employees and registered representatives of financial
      institutions that have a selling group agreement with the Distributor and
      their spouses and children under 21 years of age when purchasing for any
      accounts they beneficially own, or, in the case of any such financial
      institution, when purchasing for retirement plans for such institution's
      employees.
    
 
   
  (4) Registered investment advisers, trust companies and bank trust departments
      investing on their own behalf or on behalf of their clients provided that
      the aggregate amount invested in Class A Shares of the Fund alone, or any
      combination of shares of the Fund and shares of other Participating Funds
      as described herein under "Purchase of Shares -- Class A Shares --
      Quantity Discounts," during the 13-month period commencing with the first
      investment pursuant hereto equals at least $1 million. The Distributor may
      pay brokers, dealers or financial intermediaries through which purchases
      are made an amount up to 0.50% of the amount invested, over a 12-month
      period following such transaction.
    
 
   
  (5) Trustees and other fiduciaries purchasing shares for retirement plans of
      organizations with retirement plan assets of $3 million or more and which
      invest in multiple fund families through national wirehouse alliance
      programs.
    
 
  (6) Accounts as to which a broker, dealer or financial intermediary charges an
      account management fee ("wrap accounts"), provided the broker, dealer or
      financial intermediary has a separate agreement with the Distributor.
 
  (7) Investors purchasing shares of the Fund with redemption proceeds from
      other mutual fund complexes on which the investor has paid a front-end
      sales charge or was subject to a deferred sales charge, whether or not
      paid, if such redemption has occurred no more than 30 days prior to such
      purchase.
 
   
  (8) Trusts created under pension, profit sharing or other employee benefit
      plans qualified under Section 401(a) of the Code, or custodial accounts
      held by a bank created pursuant to Section 403(b) of the Code and
      sponsored by non-profit organizations defined under Section 501(c)(3) of
      the Code and assets held by an employer or trustee in connection with an
      eligible deferred compensation plan under Section 457 of the Code. Such
      plans will qualify for purchases at net asset value provided, for plans
      initially establishing accounts with the Distributor in the Participating
      Funds after February 1, 1997, that (1) the initial amount invested in the
      Participating Funds is at least $500,000 or (2) such shares are purchased
      by an employer sponsored plan with more than 100 eligible employees. Such
      plans that have been established with a Participating Fund or have
      received proposals from the Distributor prior to February 1, 1997 based on
      net asset value purchase privileges previously in effect will be qualified
      to purchase shares of the Participating Funds at net asset value for
      accounts established on or before
    
 
                                       30
<PAGE>   332
 
   
      May 1, 1997. Section 403(b) and similar accounts for which Van Kampen
      American Capital Trust Company served as custodian will not be eligible
      for net asset value purchases based on the aggregate investment made by
      the plan or the number of eligible employees, except under certain uniform
      criteria established by the Distributor from time to time. Prior to
      February 1, 1997, a commission will be paid to authorized dealers who
      initiate and are responsible for such purchases within a rolling
      twelve-month period as follows: 1.00% on sales to $5 million, plus 0.50%
      on the next $5 million and 0.25% on the excess over $10 million. For
      purchases on February 1, 1997 and thereafter, a commission will be paid as
      follows: 1.00% on sales to $2 million, plus 0.80% on the next $1 million,
      plus 0.50% on the next $47 million and 0.25% on the excess over $50
      million.
    
 
   
  (9) Individuals who are members of a "qualified group". For this purpose, a
      qualified group is one which (i) has been in existence for more than six
      months, (ii) has a purpose other than to acquire shares of the Fund or
      similar investments, (iii) has given and continues to give its endorsement
      or authorization, on behalf of the group, for purchase of shares of the
      Fund and other Participating Funds, (iv) has a membership that the
      authorized dealer can certify as to the group's members and (v) satisfies
      other uniform criteria established by the Distributor for the purpose of
      realizing economics of scale in distributing such shares. A qualified
      group does not include one whose sole organizational nexus, for example,
      is that its participants are credit card holders of the same institution,
      policy holders of an insurance company, customers of a bank or
      broker-dealer, clients of an investment adviser or other similar groups.
      Shares purchased in each group's participants account in connection with
      this privilege will be subject to a CDSC of 1.00% in the event of
      redemption within one year of purchase, and a commission will be paid to
      authorized dealers who initiate and are responsible for such sales to each
      individual as follows: 1.00% on sales to $2 million, plus 0.80% on the
      next $1 million and 0.50% on the excess over $3 million.
    
 
   
The term "families" includes a person's spouse, children under 21 years of age
and grandchildren, parents, and a person's spouse's parents.
    
 
   
  Purchase orders made pursuant to clause (4) may be placed either through
authorized brokers, dealers or financial intermediaries as described above or
directly with ACCESS, the investment adviser, trust company or bank trust
department, provided that ACCESS receives federal funds for the purchase by the
close of business on the next business day following acceptance of the order. An
authorized broker, dealer or financial intermediary may charge a transaction fee
for placing an order to purchase shares pursuant to this provision or for
placing a redemption order with respect to such shares. The Fund may terminate,
or amend the terms of, offering shares of the Fund at net asset value to such
groups at any time.
    
 
                                       31
<PAGE>   333
 
DEFERRED SALES CHARGE ALTERNATIVE
 
   
  Investors choosing the deferred sales charge alternative may purchase Class A
Shares in an amount of $1 million or more, Class B Shares or Class C Shares. The
public offering price of a CDSC Share is equal to the net asset value per share
without the imposition of a sales charge at the time of purchase. CDSC Shares
are sold without an initial sales charge so that the Fund may invest the full
amount of the investor's purchase payment. The Distributor will compensate
brokers, dealers and financial intermediaries participating in the continuous
public offering of the CDSC Shares out of its own assets, and not out of assets
of the Fund, as a percentage rate of the dollar value of the CDSC Shares
purchased from the Fund by such brokers, dealers and financial intermediaries
which percentage rate will be equal to (i) with respect to Class A Shares, 1.00%
on sales to $2 million, plus 0.80% on the next $1 million and 0.50% on the
excess over $3 million; (ii) 4.00% with respect to Class B Shares; and (iii)
1.00% with respect to Class C Shares. Such compensation will not change the
price an investor will pay for CDSC Shares or the amount that the Fund will
receive from such sale.
    
 
   
  CDSC Shares redeemed within a specified period of time generally will be
subject to a CDSC at the rates set forth below charged as a percentage of the
dollar amount subject thereto. The amount of the CDSC will vary depending on (i)
the class of CDSC Shares to which such shares belong and (ii) the number of
years from the time of payment for the purchase of the CDSC Shares until the
time of their redemption. The charge will be assessed on an amount equal to the
lesser of the then current market value or the original purchase price of the
CDSC Shares being redeemed. Accordingly, no sales charge will be imposed on
increases in net asset value above the initial purchase price. In addition, no
CDSC will be assessed on CDSC Shares derived from reinvestment of dividends or
capital gains distributions. Solely for purposes of determining the number of
years from the time of any payment for the purchases of CDSC Shares, all
payments during a month will be aggregated and deemed to have been made on the
last day of the month.
    
 
   
  Proceeds from the CDSC and the distribution fee applicable to a class of CDSC
Shares are paid to the Distributor and are used by the Distributor to defray its
expenses related to providing distribution related services to the Fund in
connection with the sale of shares of such class of CDSC Shares, such as the
payment of compensation to selected dealers and agents and for selling such
shares. The combination of the CDSC and the distribution fee facilitates the
ability of the Fund to sell such CDSC Shares without a sales charge being
deducted at the time of purchase.
    
 
   
  In determining whether a CDSC is applicable to a redemption of CDSC Shares, it
will be assumed that the redemption is made first of any CDSC Shares acquired
pursuant to reinvestment of dividends or distributions, second of CDSC Shares
that have been held for a sufficient period of time such that the CDSC no longer
is applicable to such shares, third of Class A Shares in the shareholder's Fund
account that have converted from Class B Shares or Class C Shares, if any, and
fourth of
    
 
                                       32
<PAGE>   334
 
   
CDSC Shares held longest during the period of time that a CDSC is applicable to
such CDSC Shares. The charge will not be applied to dollar amounts representing
an increase in the net asset value since the time of purchase.
    
 
  To provide an example, assume an investor purchased 100 Class B Shares at $10
per share (at a cost of $1,000) and in the second year after purchase, the net
asset value per share is $12 and, during such time, the investor has acquired 10
additional Class B Shares upon dividend reinvestment. If at such time the
investor makes his first redemption of 50 shares (proceeds of $600), 10 shares
will not be subject to charge because of dividend reinvestment. With respect to
the remaining 40 shares, the charge is applied only to the original cost of $10
per share and not to the increase in net asset value of $2 per share. Therefore,
$400 of the $600 redemption proceeds will be charged at a rate of 3.75% (the
applicable rate in the second year after purchase).
 
   
  CLASS A SHARE PURCHASES OF $1 MILLION OR MORE. No sales charge is payable at
the time of purchase on investments in Class A Shares of $1 million or more,
although for such investments the Fund imposes a CDSC of 1.00% on redemptions
made within one year of the purchase. A commission will be paid to dealers who
initiate and are responsible for purchases of $1 million or more as follows:
1.00% on sales to $2 million, plus 0.80% on the next $1 million and 0.50% on the
excess over $3 million.
    
 
   
  CLASS B SHARES. Class B Shares redeemed within seven years of purchase
generally will be subject to a CDSC at the rates set forth below, charged as a
percentage of the dollar amount subject thereto:

  The CDSC generally is waived on redemptions of Class B Shares made pursuant to
the Systematic Withdrawal Plan. See "Shareholder Services -- Systematic
Withdrawal Plan."
    
 
   
  CLASS C SHARES. Class C Shares redeemed within the first 12 months of purchase
generally will be subject to a CDSC of 1.00% of the dollar amount subject
thereto. Class C Shares redeemed thereafter will not be subject to a CDSC.
    
 
                                       33
<PAGE>   335
 
   
  CONVERSION FEATURE. Class B Shares purchased on or after June 1, 1996 and any
dividend reinvestment plan shares received thereon, automatically convert to
Class A Shares eight years after the end of the calendar month in which the
shares were purchased. Class B Shares purchased before June 1, 1996, and any
dividend reinvestment plan shares received thereon, automatically convert to
Class A Shares seven years after the end of the calendar month in which the
shares were purchased. Class C Shares purchased before January 1, 1997, and any
dividend reinvestment plan shares received thereon, automatically convert to
Class A Shares ten years after the end of the calendar month in which such
shares were purchased. Such conversion will be on the basis of the relative net
asset values per share, without the imposition of any sales load, fee or other
charge.
    
 
   
  The conversion of such shares to Class A Shares is subject to the continuing
availability of an opinion of counsel to the effect that (i) the assessment of
the higher distribution and service fees and ACCESS costs with respect to such
shares does not result in the Fund's dividends or distributions constituting
"preferential dividends" under the Internal Revenue Code of 1986, as amended
(the "Code"), and (ii) that the conversion of such shares does not constitute a
taxable event under federal income tax law. The conversion may be suspended if
such an opinion is no longer available and such shares might continue to be
subject to the higher aggregate fees applicable to such class of shares for an
indefinite period.
    
 
   
  WAIVER OF CONTINGENT DEFERRED SALES CHARGE. The CDSC is waived on redemptions
of Class B Shares and Class C Shares (i) following the death or disability (as
defined in the Code) of a shareholder, (ii) in connection with required minimum
distributions from an IRA or other retirement plan, (iii) pursuant to the Fund's
systematic withdrawal plan but limited to 12% annually of the initial value of
the account and (iv) effected pursuant to the right of the Fund to liquidate a
shareholder's account as described herein under "Redemption of Shares." The CDSC
also is waived on redemptions of Class C Shares as it relates to the
reinvestment of redemption proceeds in shares of the same class of the Fund
within 120 days after redemption. See "Shareholder Services" and "Redemption of
Shares" for further discussion of the waiver provisions.
    
 
NET ASSET VALUE
 
  The net asset value per share of the Fund will be determined separately for
each class of shares. The net asset value per share of a given class of shares
of the Fund is determined by calculating the total value of the Fund's assets
attributable to such class of shares, deducting its total liabilities
attributable to such class of shares, and dividing the result by the number of
shares of such class outstanding. The net asset value for the Fund is computed
once daily as of 5:00 p.m. Eastern time Monday through Friday, except on
customary business holidays, or except on any day on which no purchase or
redemption orders are received, or there is not a sufficient degree of trading
in the Fund's portfolio securities such that the Fund's net asset value per
share might be materially affected. The Fund reserves the right to
 
                                       34
<PAGE>   336
 
calculate the net asset value and to adjust the public offering price based
thereon more frequently than once a day if deemed desirable. The net asset value
per share of the different class of shares are expected to be substantially the
same; from time to time, however, the per share net asset value of the different
class of shares may differ.
 
  Portfolio securities are valued by using market quotations, prices provided by
market makers or estimates of market values obtained from yield data relating to
instruments or securities with similar characteristics in accordance with
procedures established in good faith by the Board of Trustees of the Trust, of
which the Fund is a series. Securities with remaining maturities of 60 days or
less are valued at amortized cost when amortized cost is determined in good
faith by or under the direction of the Board of Trustees of the Trust to be
representative of the fair value at which it is expected such securities may be
resold. Any securities or other assets for which current market quotations are
not readily available are valued at their fair value as determined in good faith
under procedures established by and under the general supervision of the Board
of Trustees of the Trust.
 
- ------------------------------------------------------------------------------
SHAREHOLDER SERVICES
- ------------------------------------------------------------------------------
 
  The Fund offers a number of shareholder services designed to facilitate
investment in its shares at little or no extra cost to the investor. Below is a
description of such services. Unless otherwise described below, each of these
services may be modified or terminated by the Fund at any time.
 
   
  INVESTMENT ACCOUNT. ACCESS, transfer agent for the Fund and a wholly-owned
subsidiary of Van Kampen American Capital, performs bookkeeping, data processing
and administration services related to the maintenance of shareholder accounts.
Each shareholder has an investment account under which shares are held by
ACCESS. Except as described in this Prospectus, after each share transaction in
an account, the shareholder receives a statement showing the activity in the
account. Each shareholder will receive statements at least quarterly from ACCESS
showing any reinvestments of dividends and capital gains distributions and any
other activity in the account since the preceding statement. Such shareholders
also will receive separate confirmations for each purchase or sale transaction
other than reinvestment of dividends and capital gains distributions and
systematic purchases or redemptions. Additions to an investment account may be
made at any time by purchasing shares through authorized brokers, dealers or
financial intermediaries or by mailing a check directly to ACCESS.
    
 
  SHARE CERTIFICATES. Generally, the Fund will not issue share certificates.
However, upon written or telephone request to the Fund, a share certificate will
be issued, representing shares (with the exception of fractional shares) of the
Fund. A shareholder will be required to surrender such certificates upon
redemption thereof. In addition, if such certificates are lost the shareholder
must write to Van Kampen American Capital Funds, c/o ACCESS, P.O. Box 418256,
Kansas City, MO
 
                                       35
<PAGE>   337
 
64141-9256, requesting an "affidavit of loss" and to obtain a Surety Bond in a
form acceptable to ACCESS. On the date the letter is received ACCESS will
calculate a fee for replacing the lost certificate equal to no more than 2.00%
of the net asset value of the issued shares and bill the party to whom the
replacement certificate was mailed.
 
   
  REINVESTMENT PLAN. A convenient way for investors to accumulate additional
shares is by accepting dividends and capital gains distributions in shares of
the Fund. Such shares are acquired at net asset value per share (without sales
charge) on the record date of such dividend or distribution. Unless the
shareholder instructs otherwise, the reinvestment plan is automatic. This
instruction may be made by telephone by calling (800) 421-5666 ((800) 421-2833
for the hearing impaired) or in writing to ACCESS. The investor may, on the
initial application or prior to any declaration, instruct that dividends be paid
in cash and capital gains distributions be reinvested at net asset value, or
that both dividends and capital gains distributions be paid in cash. For further
information, see "Distributions from the Fund."
    
 
  AUTOMATIC INVESTMENT PLAN. An automatic investment plan is available under
which a shareholder can authorize ACCESS to charge a bank account on a regular
basis to invest pre-determined amounts in the Fund. Additional information is
available from the Distributor or authorized brokers, dealers or financial
intermediaries.
 
   
  DIVIDEND DIVERSIFICATION. A shareholder may, upon written request or by
completing the appropriate section of the application form accompanied by this
Prospectus or by calling (800) 421-5666 ((800) 421-2833 for the hearing
impaired), elect to have all dividends and other distributions paid on a class
of shares of the Fund invested into shares of the same class of any other
Participating Fund, Tax Free Money Fund or Reserve Fund so long as a
pre-existing account for such class of shares exists for such shareholder.
    
 
  If the qualified pre-existing account does not exist, the shareholder must
establish a new account subject to minimum investment and other requirements of
the fund into which distributions would be invested. Distributions are invested
into the selected fund at its net asset value as of the payable date of the
distribution only if shares of such selected fund have been registered for sale
in the investor's state.
 
   
  EXCHANGE PRIVILEGE. Shares of the Fund may be exchanged with shares of another
Participating Fund subject to certain limitations. Before effecting an exchange,
shareholders in the Fund should obtain and read a current prospectus of the fund
into which the exchange is to be made. SHAREHOLDERS MAY ONLY EXCHANGE INTO SUCH
OTHER FUNDS AS ARE LEGALLY AVAILABLE FOR SALE IN THEIR STATE.
    
 
  To be eligible for exchange, shares of the Fund must have been registered in
the shareholder's name for at least 30 days prior to an exchange. Shares of the
Fund registered in a shareholder's name for less than 30 days may only be
exchanged upon receipt of prior approval of the Adviser. Under normal
circumstances, it is the policy of the Adviser not to approve such requests.
 
                                       36
<PAGE>   338
 
  Class A Shares of Van Kampen American Capital funds that generally impose an
initial sales charge are not subject to any sales charge upon exchange into the
Fund. Class A Shares of Van Kampen American Capital funds that generally do not
impose an initial sales charge are subject to the appropriate sales charge
applicable to Class A Shares of the Fund.
 
   
  No sales charge is imposed upon the exchange of a Class B Shares or Class C
Shares. The CDSC schedule and conversion schedule applicable to a Class B Share
or Class C Share acquired through the exchange privilege is determined by
reference to the Van Kampen American Capital fund from which such share
originally was purchased. The holding period of a Class B Share or Class C Share
acquired through the exchange privilege is determined by reference to the date
such share originally was purchased from a Van Kampen American Capital fund.
    
 
  Exchanges of shares are sales and may result in a gain or loss for federal
income tax purposes. If the shares exchanged have been held for less than 91
days, the sales charge paid on such shares is not included in the tax basis of
the exchanged shares, but is carried over and included in the tax basis of the
shares acquired.
 
   
  A shareholder wishing to make an exchange may do so by sending a written
request to ACCESS or by contacting the telephone transaction line at (800)
421-5684 ((800) 421-2833 for the hearing impaired). A shareholder automatically
has telephone exchange privileges unless otherwise designated in the application
form accompanied by this Prospectus. The exchange will take place at the
relative net asset values of the shares next determined after receipt of such
request with adjustment for any additional sales charge. Any shares exchanged
begin earning dividends on the next business day after the exchange is affected.
Van Kampen American Capital and its subsidiaries, including ACCESS
(collectively, "VKAC"), and the Fund employ procedures considered by them to be
reasonable to confirm that instructions communicated by telephone are genuine.
Such procedures include requiring certain personal identification information
prior to acting upon telephone instructions, tape recording telephone
communications, and providing written confirmation of instructions communicated
by telephone. If reasonable procedures are employed, a shareholder agrees that
neither VKAC nor the Fund will be liable for following telephone instructions
which it reasonably believes to be genuine. VKAC and the Fund may be liable for
any losses due to unauthorized or fraudulent instructions if reasonable
procedures are not followed. Exchanges are effected at the net asset value per
share next calculated after the request is received in good order with
adjustment for any additional sales charges. If the exchanging shareholder does
not have an account in the fund whose shares are being acquired, a new account
will be established with the same registration, dividend and capital gains
options (except dividend diversification options) and broker, dealer or
financial intermediary of record as the account from which shares are exchanged,
unless otherwise specified by the shareholder. In order to establish a
systematic withdrawal plan for the new account or reinvest dividends from the
new account into another fund, an exchanging shareholder must file a specific
written request. The Fund reserves the right to reject any order to acquire
shares through
    
 
                                       37
<PAGE>   339
 
   
exchange. In addition, the Fund may modify, restrict or terminate the exchange
privilege at any time on 60 days' notice to its shareholders of any termination
or material amendment.
    
 
   
  A prospectus of any of these mutual funds may be obtained from any broker,
dealer or financial intermediary or the Distributor. An investor considering an
exchange to one of such funds should refer to the prospectus for additional
information regarding such fund prior to investing.
    
 
   
  SYSTEMATIC WITHDRAWAL PLAN. Any investor whose shares in a single account
total $10,000 or more at the offering price next computed after receipt of
instructions may establish a monthly, quarterly, semi-annual or annual
withdrawal plan. Any investor whose shares in a single account total $5,000 or
more at the offering price next computed after receipt of instructions may
establish a quarterly, semi-annual or annual or annual withdrawal plan. This
plan provides for the orderly use of the entire account, not only the income but
also the capital, if necessary. Each withdrawal constitutes a redemption of
shares on which taxable gain or loss will be recognized. The plan holder may
arrange for monthly, quarterly, semi-annual, or annual checks in any amount not
less than $25.
    
 
   
  Holders of Class B Shares and Class C Shares who establish a withdrawal plan
may redeem up to 12% annually of the shareholder's initial account balance
without incurring a contingent deferred sales charge. Initial account balance
means the amount of the shareholder's investment at the time the election to
participate in the plan is made.
    
 
  Under the plan, sufficient shares of the Fund are redeemed to provide the
amount of the periodic withdrawal payment. Dividends and capital gains
distributions on shares held under the plan are reinvested in additional shares
at the next determined net asset value. If periodic withdrawals continuously
exceed reinvested dividends and capital gains distributions, the shareholder's
original investment will be correspondingly reduced and ultimately exhausted.
Withdrawals made concurrently with purchases of additional shares ordinarily
will be disadvantageous to the shareholder because of the duplication of sales
charges. The Fund reserves the right to amend or terminate the systematic
withdrawal program on thirty days' notice to its shareholders.
 
  CHECK WRITING PRIVILEGE. Holders of Class A Shares of the Fund for which
certificates have not been issued and which are in a non-escrow status may
appoint ACCESS as agent by completing the Authorization for Redemption by Check
Form and the appropriate section of the application and returning the form and
the application to ACCESS. Once the form is properly completed, signed and
returned to the agent, a supply of checks drawn on State Street Bank and Trust
Company ("State Street Bank") will be sent to such shareholder. These checks may
be made payable by the holder of Class A Shares to the order of any person in
any amount of $100 or more.
 
                                       38
<PAGE>   340
 
  When a check is presented to State Street Bank for payment, full and
fractional Class A Shares required to cover the amount of the check are redeemed
from the shareholder's account by ACCESS at the next determined net asset value.
Check writing redemptions represent the sale of Class A Shares. Any gain or loss
realized on the sale of Class A Shares is a taxable event. See "Redemption of
Shares."
 
   
  Checks will not be honored for redemption of Class A Shares held less than 15
calendar days, unless such Class A Shares have been paid for by bank wire. Any
Class A Shares for which there are outstanding certificates may not be redeemed
by check. If the amount of the check is greater than the proceeds of all
uncertificated shares held in the shareholder's Class A Share account, the check
will be returned and the shareholder may be subject to additional charges.
Holders of Class A Shares may not liquidate the entire account by means of a
check. The check writing privilege may be terminated or suspended at any time by
the Fund or State Street Bank. Retirement plans and accounts that are subject to
backup withholding are not eligible for the privilege. A "stop payment" system
is not available on these checks. See the Statement of Additional Information
for further information regarding the establishment of the privilege.
    
 
  AUTOMATED CLEARING HOUSE ("ACH") DEPOSITS. Holders of Class A Shares can use
ACH to have redemption proceeds deposited electronically into their bank
accounts. Redemptions transferred to a bank account via the ACH plan are
available to be credited to the account on the second business day following
normal payment. In order to utilize this option, the shareholder's bank must be
a member of Automated Clearing House. In addition, the shareholder must fill out
the appropriate section of the account application. The shareholder must also
include a voided check or deposit slip from the bank account into which
redemptions are to be deposited together with the completed application. Once
ACCESS has received the application and the voided check or deposit slip, such
shareholder's designated bank account, following any redemption, will be
credited with the proceeds of such redemption. Once enrolled in the ACH plan, a
shareholder may terminate participation at any time by writing ACCESS.
 
- ------------------------------------------------------------------------------
REDEMPTION OF SHARES
- ------------------------------------------------------------------------------
 
  Shareholders may redeem for cash some or all of their shares without charge by
the Fund (other than, with respect to CDSC Shares, the applicable contingent
deferred sales charge) at any time by sending a written request in proper form
directly to ACCESS, P. O. Box 418256, Kansas City, Missouri 64141-9256, by
placing the redemption request through an authorized dealer or by calling the
Fund.
 
  WRITTEN REDEMPTION REQUESTS. In the case of redemption requests sent directly
to ACCESS, the redemption request should indicate the number of shares to be
redeemed, the class designation of such shares, the account number and be signed
exactly as the shares are registered. Signatures must conform exactly to the
account registration. If the proceeds of the redemption would exceed $50,000, or
if the
 
                                       39
<PAGE>   341
 
proceeds are not to be paid to the record owner at the record address, or if the
record address has changed within the previous 30 days, signature(s) must be
guaranteed by one of the following: a bank or trust company; a broker-dealer; a
credit union; a national securities exchange, registered securities association
or clearing agency; a savings and loan association; or a federal savings bank.
If certificates are held for the shares being redeemed, such certificates must
be endorsed for transfer or accompanied by an endorsed stock power and sent with
the redemption request. In the event the redemption is requested by a
corporation, partnership, trust, fiduciary, executor or administrator, and the
name and title of the individual(s) authorizing such redemption is not shown in
the account registration, a copy of the corporate resolution or other legal
documentation appointing the authorized signer and certified within the prior 60
days must accompany the redemption request. The redemption price is the net
asset value per share next determined after the request is received by ACCESS in
proper form. Payment for shares redeemed (less any sales charge, if applicable)
will ordinarily be made by check mailed within three business days after
acceptance by ACCESS of the request and any other necessary documents in proper
order. Such payments may be postponed or the right of redemption suspended as
provided by the rules of the SEC. If the shares to be redeemed have been
recently purchased by check, ACCESS may delay mailing a redemption check until
it confirms that the purchase check has cleared, usually a period of up to 15
days. Any gain or loss realized on the redemption of shares is a taxable event.
 
  DEALER REDEMPTION REQUESTS. Shareholders may sell shares through their
securities dealer, who will telephone the request to the Distributor. Orders
received from dealers must be at least $500 unless transmitted via the FUNDSERV
network. The redemption price for such shares is the net asset value next
calculated after an order is received by a dealer provided such order is
transmitted to the Distributor prior to the Distributor's close of business on
such day. It is the responsibility of dealers to transmit redemption requests
received by them to the Distributor so they will be received prior to such time.
Any change in the redemption price due to failure of the Distributor to receive
a sell order prior to such time must be settled between the shareholder and
dealer. Shareholders must submit a written redemption request in proper form (as
described above under "Written Redemption Requests") to the dealer within three
business days after calling the dealer with the sell order. Payment for shares
redeemed (less any sales charge, if applicable) will ordinarily be made by check
mailed within three business days to the dealer.
 
   
  TELEPHONE REDEMPTION REQUESTS. The Fund permits redemption of shares by
telephone and for redemption proceeds to be sent to the address of record for
the account or to the bank account of record as described below. To establish
such privilege, a shareholder must complete the appropriate section of the
application accompanying this Prospectus or call the Fund at (800) 421-5666
((800) 421-2833 for the hearing impaired) to request that a copy of the
Telephone Redemption Authorization form be sent to them for completion. To
redeem shares, contact the telephone transaction line at (800) 421-5684. VKAC
and the Fund employ
    
 
                                       40
<PAGE>   342
 
procedures considered by them to be reasonable to confirm that instructions
communicated by telephone are genuine. Such procedures include requiring certain
personal identification information prior to acting upon telephone instructions,
tape recording telephone communications, and providing written confirmation of
instructions communicated by telephone. If reasonable procedures are employed, a
shareholder agrees that neither VKAC nor the Fund will be liable for following
instructions which it reasonably believes to be genuine. VKAC and the Fund may
be liable for any losses due to unauthorized or fraudulent instructions if
reasonable procedures are not followed. Telephone redemptions may not be
available if the shareholder cannot reach ACCESS by telephone, whether because
all telephone lines are busy or for any other reason; in such case, a
shareholder would have to use the Fund's other redemption procedures previously
described. Requests received by ACCESS prior to 4:00 p.m., New York time, on a
regular business day will be processed at the net asset value per share
determined that day. These privileges are available for all accounts other than
retirement accounts. The telephone redemption privilege is not available for
shares represented by certificates. If the shares to be redeemed have been
recently purchased by check, ACCESS may delay mailing a redemption check or
wiring redemption proceeds until it confirms that the purchase check has
cleared, usually a period of up to 15 days. If an account has multiple owners,
ACCESS may rely on the instructions of any one owner.
 
  For redemptions authorized by telephone, amounts of $50,000 or less may be
redeemed daily if the proceeds are to be paid by check sent to the shareholders'
address of record and amounts of at least $1,000 and up to $1 million may be
redeemed daily if the proceeds are to be paid by wire sent to the shareholder's
bank account of record. The proceeds must be payable to the shareholder(s) of
record. Proceeds from redemptions to be paid by check will ordinarily be mailed
within three business days to the shareholder's address of record. Proceeds from
redemptions to be paid by wire will ordinarily be wired on the next business day
to the shareholder's bank account of record. This privilege is not available if
the address of record has been changed within 30 days prior to a telephone
redemption request. The Fund reserves the right at any time to terminate, limit
or otherwise modify this telephone redemption privilege.
 
   
  REDEMPTION UPON DISABILITY. The Fund will waive the CDSC on redemptions
following the disability of holders of Class B Shares and Class C Shares. An
individual will be considered disabled for this purpose if he or she meets the
definition thereof in Section 72(m)(7) of the Code, which in pertinent part
defines a person as disabled if such person "is unable to engage in any
substantial gainful activity by reason of any medically determinable physical or
mental impairment which can be expected to result in death or to be of
long-continued and indefinite duration." While the Fund does not specifically
adopt the balance of the Code's definition which pertains to furnishing the
Secretary of Treasury with such proof as he or she may require, the Distributor
will require satisfactory proof of disability before it determines to waive the
CDSC on Class B Shares and Class C Shares.
    
 
                                       41
<PAGE>   343
 
   
  In cases of disability, the CDSCs on Class B Shares and Class C Shares will be
waived where the disabled person is either an individual shareholder or owns the
shares as a joint tenant with right of survivorship or is the beneficial owner
of a custodial or fiduciary account, and where the redemption is made within one
year of the initial determination of disability. This waiver of the CDSC on
Class B Shares and Class C Shares applies to a total or partial redemption, but
only to redemptions of shares held at the time of the initial determination of
disability.
    
 
   
  GENERAL REDEMPTION INFORMATION. The Fund may redeem any shareholder account
with a net asset value on the date of the notice of redemption less than the
minimum investment as specified by the Trustees. At least 60 days advance
written notice of any such involuntary redemption is required and the
shareholder is given an opportunity to purchase the required value of additional
shares at the next determined net asset value without sales charge. Any
applicable CDSC will be deducted from the proceeds of this redemption. Any
involuntary redemption may only occur if the shareholder account is less than
the minimum investment due to shareholder redemptions.
    
 
   
  REINSTATEMENT PRIVILEGE. Holders of Class A Shares or Class B Shares who have
redeemed shares of the Fund may reinstate any portion or all of the net proceeds
of such redemption in Class A Shares of the Fund. Holders of Class C Shares who
have redeemed shares of the Fund may reinstate any portion or all of the net
proceeds of such redemption in Class C Shares of the Fund with credit given for
any CDSC paid upon such redemption. Such reinstatement is made at the net asset
value (without sales charge except as described under "Shareholder Services --
Exchange Privilege") next determined after the order is received, which must be
within 180 days after the date of the redemption. See "Purchase of
Shares -- Waiver of Contingent Deferred Sales Charge." Reinstatement at net
asset value is also offered to participants in those eligible retirement plans
held or administered by Van Kampen American Capital Trust Company for repayment
of principal (and interest) on their borrowings on such plans.

DISTRIBUTION AND SERVICE PLANS
    
- ------------------------------------------------------------------------------
 
  The Fund has adopted a distribution plan (the "Distribution Plan") with
respect to each class of its shares pursuant to Rule 12b-1 under the 1940 Act.
The Fund also has adopted a service plan (the "Service Plan") with respect to
each class of its shares. The Distribution Plan and the Service Plan provide
that the Fund may spend a portion of the Fund's average daily net assets
attributable to each class of shares in connection with distribution of the
respective class of shares and in connection with the provision of ongoing
services to shareholders of each class. The Distribution Plan and the Service
Plan are being implemented through an agreement with the Distributor and
sub-agreements between the Distributor and brokers, dealers or financial
intermediaries (collectively, "Selling Agreements") that may provide for their
customers or clients certain services or assistance.
 
                                       42
<PAGE>   344
 
   
  CLASS A SHARES. The Fund may spend an aggregate amount up to 0.25% per year of
the average daily net assets attributable to the Class A Shares of the Fund
pursuant to the Distribution Plan and Service Plan. From such amount, the Fund
may spend up to 0.25% per year of the Fund's average daily net assets
attributable to the Class A Shares pursuant to the Service Plan in connection
with the ongoing provision of services to holders of such shares by the
Distributor and by brokers, dealers or financial intermediaries and in
connection with the maintenance of such shareholders' accounts. The Fund pays
the Distributor the lesser of the balance of the 0.25% not paid to such brokers,
dealers or financial intermediaries or the amount of the Distributor's actual
distribution-related expense.
    
 
  CLASS B SHARES. The Fund may spend up to 0.75% per year of the average daily
net assets attributable to the Class B Shares of the Fund pursuant to the
Distribution Plan. In addition, the Fund may spend up to 0.25% per year of the
Fund's average daily net assets attributable to the Class B Shares pursuant to
the Service Plan in connection with the ongoing provision of services to holders
of such shares by the Distributor and by brokers, dealers or financial
intermediaries and in connection with the maintenance of such shareholders'
accounts.
 
   
  CLASS C SHARES. The Fund may spend up to 0.75% per year of the average daily
net assets attributable to the Class C Shares of the Fund pursuant to the
Distribution Plan. From such amount, the Fund, or the Distributor as agent for
the Fund, pays brokers, dealers or financial intermediaries in connection with
the distribution of the Class C Shares up to 0.75% of the Fund's average daily
net assets attributable to Class C Shares maintained in the Fund more than one
year by such broker's, dealer's or financial intermediary's customers. The Fund
pays the Distributor the lesser of the balance of 0.75% not paid to such
brokers, dealers or financial intermediaries or the amount of the Distributor's
actual distribution-related expense attributable to the Class C Shares. In
addition, the Fund may spend up to 0.25% per year of the Fund's average daily
net assets attributable to the Class C Shares pursuant to the Service Plan in
connection with the ongoing provision of services to holders of such shares by
the Distributor and by brokers, dealers or financial intermediaries and in
connection with the maintenance of such shareholders' accounts.
    
 
  OTHER INFORMATION. Amounts payable to the Distributor with respect to the
Class A Shares under the Distribution Plan in a given year may not fully
reimburse the Distributor for its actual distribution-related expenses during
such year. In such event, with respect to the Class A Shares, there is no
carryover of such reimbursement obligations to succeeding years.
 
   
  The Distributor's actual expenses with respect to a class of CDSC Shares (for
purposes of this section, excluding any Class A Shares that may be subject to a
CDSC) for any given year may exceed the amounts payable to the Distributor with
respect to such class of CDSC Shares under the Distribution Plan, the Service
Plan and payments received pursuant to the CDSC. In such event, with respect to
any such class of CDSC Shares, any unreimbursed expenses will be carried forward
and
    
 
                                       43
<PAGE>   345
 
   
paid by the Fund (up to the amount of the actual expenses incurred) in future
years so long as such Distribution Plan is in effect. Except as mandated by
applicable law, the Fund does not impose any limit with respect to the number of
years into the future that such unreimbursed expenses may be carried forward (on
a Fund level basis). Because such expenses are accounted on a Fund level basis,
in periods of extreme net asset value fluctuation such amounts with respect to a
particular CDSC Share may be greater or less than the amount of the initial
commission (including carrying cost) paid by the Distributor with respect to
such CDSC Share. In such circumstances, a shareholder of such CDSC Share may be
deemed to incur expenses attributable to other shareholders of such class. As of
December 31, 1996, there were $408,097 and $6,707 of unreimbursed distribution
related expenses with respect to Class B Shares and Class C Shares,
respectively, representing 4.52% and 0.94% of the Fund's net assets attributable
to Class B Shares and Class C Shares, respectively. If the Distribution Plan was
terminated or not continued, the Fund would not be contractually obligated to
pay the Distributor for any expenses not previously reimbursed by the Fund or
recovered through CDSCs.
    
 
   
  Because the Fund is a series of the Trust, amounts paid to the Distributor as
reimbursement for expenses of one series of the Trust may indirectly benefit the
other funds which are series of the Trust. The Distributor will endeavor to
allocate such expenses among such funds in an equitable manner. The Distributor
will not use the proceeds from the CDSC applicable to a particular class of
shares to defray distribution-related expenses attributable to any other class
of shares. Various federal and state laws prohibit national banks and some
state-chartered commercial banks from underwriting or dealing in the Fund's
shares. In addition, state securities laws on this issue may differ from the
interpretations of federal law, and banks and financial institutions may be
required to register as dealers pursuant to state law. In the unlikely event
that a court were to find that these laws prevent such banks from providing such
services described above, the Fund would seek alternate providers and expects
that shareholders would not experience any disadvantage.
    
 
- ------------------------------------------------------------------------------
DISTRIBUTIONS FROM THE FUND
- ------------------------------------------------------------------------------
 
  The Fund's present policy, which may be changed at any time by the Board of
Trustees, is to declare daily and pay monthly distributions of all or
substantially all net investment income of the Fund. Net investment income
consists of all interest income, dividends, and other ordinary income earned by
the Fund, less all expenses of the Fund attributable to the class of shares in
question. Net short-term capital gains, if any, may be distributed throughout
the year. Expenses of the Fund are accrued each day. Net realized long-term
capital gains, if any, are expected to be distributed, to the extent permitted
by applicable law, to shareholders at least annually. Distributions cannot be
assured, and the amount of each monthly distribution may vary.
 
                                       44
<PAGE>   346
 
  Distributions with respect to each class of shares will be calculated in the
same manner on the same day and will be in the same amount, except that the
different distribution and service fees and any incremental administrative
expenses relating to each class of shares will be borne exclusively by the
respective class and may cause the distributions relating to the different
classes of shares to differ. Generally, distributions with respect to a class of
shares subject to a higher distribution fee will be lower than distributions
with respect to a class of shares subject to a lower distribution fee.
 
   
  Investors will be entitled to begin receiving dividends on their shares on the
business day after ACCESS receives payments for such shares. However, shares
become entitled to dividends on the day ACCESS receives payment for the shares
either through a fed wire or NSCC settlement. Shares remain entitled to
dividends through the day such shares are processed for payment on redemption.
    
 
  Distribution checks may be sent to parties other than the shareholder in whose
name the account is registered. Persons wishing to utilize this service should
complete the appropriate section of the account application accompanying this
Prospectus or available from Van Kampen American Capital Funds, c/o ACCESS P.O.
Box 418256, Kansas City, MO 64141-9256. After ACCESS receives this completed
form, distribution checks will be sent to the bank or other person so designated
by such shareholder.
 
   
  PURCHASE OF ADDITIONAL SHARES WITH DISTRIBUTIONS. The Fund will automatically
credit monthly distributions and any annual net long-term capital gain
distributions to a shareholder's account in additional shares of the Fund valued
at net asset value, without a sales charge. Unless a shareholder instructs
otherwise, the reinvestment plan is automatic. This instruction may be made by
telephone by calling (800) 421-5666 ((800) 421-2833 for the hearing impaired) or
in writing to ACCESS. See "Shareholder Services -- Reinvestment Plan."

TAX STATUS
- ------------------------------------------------------------------------------
 
NEW JERSEY TAXATION
 
   
  The following New Jersey income tax discussion is based on the advice of
Crummy, Del Deo, Dolan, Griffinger & Vecchione, special New Jersey tax counsel
to the Fund.
    
 
  Individual shareholders of the Fund, including trusts and estates, who are
subject to the New Jersey Gross Income Tax will not be required to include in
their New Jersey gross income distributions from the Fund which the Fund clearly
identifies as directly attributable to interest or gains from New Jersey
municipal securities, obligations of the United States or any other obligations,
the interest and gain on which is exempt from New Jersey Gross Income Tax under
New Jersey law or federal law, provided that the Fund qualifies as a "qualified
investment fund."
 
                                       45
<PAGE>   347
 
  The Fund will qualify as a "qualified investment fund" if, for any calendar
year in which a distribution is paid: (1) the Fund has no investments, other
than interest-bearing obligations, obligations issued at a discount and cash and
cash items, including receivables and financial options, futures, forward
contracts, or other similar financial instruments related to interest-bearing
obligations, obligations issued at a discount or bond indexes related thereto;
(2) at the close of each quarter of the taxable year the Fund has not less than
80% of the aggregate principal amount of all of its investments (excluding
financial options, futures, forward contracts, or other similar financial
instruments related to interest-bearing obligations, obligations issued at a
discount or bond indexes related thereto to the extent such instruments are
authorized by Section 851(b) of the Internal Revenue Code of 1986, cash and cash
items, which cash items shall include receivables) in New Jersey municipal
securities, or any other obligations, including United States obligations, the
interest or gains on which is exempt from New Jersey Gross Income Tax pursuant
to New Jersey law or federal law; (3) the Fund does not engage in any prohibited
Strategic Transactions (see "Investment Practices"); and (4) the Fund satisfies
the certification and reporting requirements imposed by regulations promulgated
by the New Jersey Division of Taxation. The Fund intends to so qualify. The Fund
must certify annually on or before February 15 to the New Jersey Division of
Taxation that for the preceding calendar year the Fund is a "qualified
investment fund." The Fund must also advise the Division of Taxation as to
amounts distributed for the preceding calendar year to shareholders from income
or gain derived from New Jersey and federal obligations. The Fund must also
advise its shareholders on or before February 15 of each calendar year that its
distributions qualify for exclusion pursuant to New Jersey law regarding
qualified investment funds.
 
  Distributions to individual shareholders, including trusts and estates, who
are subject to the New Jersey Gross Income Tax, attributable to interest or
gains on municipal obligations issued by states other than New Jersey, including
municipalities or authorities in such other states, or any other obligations the
interest on which is not exempt from New Jersey Gross Income Tax pursuant to New
Jersey law or federal law, will be included as New Jersey gross income for
purposes of calculating the New Jersey Gross Income Tax.
 
  Individual shareholders of the Fund, including trusts and estates, who are
subject to the New Jersey Gross Income Tax, will not be required to include in
gross income net gains attributable to the sale of shares provided that the Fund
qualifies as a "qualified investment fund." Any loss realized on such sale may
not be utilized to offset gains realized by such shareholder on the sale of
assets the gain on which is subject to the New Jersey Gross Income Tax.
 
  If an individual holder of shares dies a domiciliary of New Jersey, New Jersey
Inheritance Tax and New Jersey Estate Tax may be imposed as a result of the
ownership of such shares.
 
                                       46
<PAGE>   348
 
  If a shareholder is a corporation subject to the New Jersey Corporation
Business Tax or the New Jersey Corporation Income Tax, distributions of interest
or gains, or both, from the Fund will be includable in its entire net income for
purposes of the New Jersey Corporation Business Tax or New Jersey Corporation
Income Tax, less any interest expense incurred to carry such investment to the
extent such interest expense has not been deducted in computing federal taxable
income. Net gains derived by such corporation on the sale of its shares will be
included in its entire net income for purposes of the New Jersey Corporation
Business Tax or New Jersey Corporation Income Tax.
 
  New Jersey S corporations that are shareholders of the Fund generally will be
subject to the Corporation Business Tax at a rate of 2.63% of their entire net
income. New Jersey S corporations with entire net income of $100,000 or less for
tax years beginning on or after July 1, 1996 will be subject to tax at a rate of
1.13%. However, New Jersey S corporations that are taxed under certain
provisions of federal tax law will be subject to the Corporation Business Tax at
a rate of 9.0% of their entire net income. Entire net income will include
distributions of the Fund and gains on the sale of shares of the Fund.
 
  The foregoing is a general, abbreviated summary of certain of the provisions
of New Jersey law presently in effect as they directly govern the taxation of
shareholders of the Fund. The provisions are subject to change by legislative or
administrative action, and any such change may be retroactive with respect to
Fund transactions.
 
FEDERAL TAXATION
 
   
  The following federal income tax discussion is based on the advice of Skadden,
Arps, Slate, Meagher & Flom (Illinois), and reflects applicable federal tax
laws.
    
 
   
  The Fund has qualified and intends to continue to qualify each year and to
elect to be treated as a regulated investment company under Subchapter M of the
Code. To qualify as a regulated investment company, the Fund must comply with
certain requirements of the Code relating to, among other things, the source of
its income and diversification of its assets.
    
 
   
  If the Fund so qualifies and distributes each year to its shareholders at
least 90% of its net investment income (including tax-exempt interest, taxable
income and net short-term capital gain, but not net capital gains, which are the
excess of net long-term capital gains over net short-term capital losses), it
will not be required to pay federal income taxes on any income distributed to
shareholders. The Fund intends to distribute at least the minimum amount of net
investment income necessary to satisfy the 90% distribution requirement. The
Fund will not be subject to federal income tax on any net capital gains
distributed to shareholders.
    
 
   
  In order to avoid a 4% excise tax, the Fund will be required to distribute, by
December 31 of each year, at least 98% of its ordinary income (not including
tax-exempt income) for such year and at least 98% of its capital gain net income
(the
    
 
                                       47
<PAGE>   349
 
   
latter of which generally is computed on the basis of the one-year period ending
on October 31 of such year), plus any amounts that were not distributed in
previous taxable years. For purposes of the excise tax, any ordinary income or
capital gain net income retained by, and subject to federal income tax in the
hands of, the Fund will be treated as having been distributed.
    
 
   
  If the Fund failed to qualify as a regulated investment company or failed to
satisfy the 90% distribution requirement in any taxable year, the Fund would be
taxed as an ordinary corporation on its taxable income (even if such income were
distributed to its shareholders) and all distributions out of earnings and
profits would be taxed to shareholders as ordinary income. To qualify again as a
regulated investment company in a subsequent year, the Fund may be required to
pay an interest charge on 50% of its earnings and profits attributable to
non-regulated investment company years and would be required to distribute such
earnings and profits to shareholders (less any interest charge). In addition, if
the Fund failed to qualify as a regulated investment company for its first
taxable year or, if immediately after qualifying as a regulated investment
company for any taxable year, it failed to qualify for a period greater than one
taxable year, the Fund would be required to recognize any net built-in gains
(the excess of aggregate gains, including items of income, over aggregate losses
that would have been realized if it had been liquidated) in order to qualify as
a regulated investment company in a subsequent year.
    
 
   
  Some of the Fund's investment practices are subject to special provisions of
the Code that, among other things, may defer the use of certain losses of the
Fund and affect the holding period of the securities held by the Fund and the
character of the gains or losses realized by the Fund. These provisions may also
require the Fund to mark-to-market some of the positions in its portfolio (i.e.,
treat them as if they were sold for fair market value at the end of the
tax-year), which may cause the Fund to recognize income without receiving cash
with which to make distributions in amounts necessary to satisfy the 90%
distribution requirement and the distribution requirements for avoiding income
and excise taxes. The Fund will monitor its transactions and may make certain
tax elections in order to mitigate the effect of these rules and prevent
disqualification of the Fund as a regulated investment company.
    
 
   
  The Fund's ability to dispose of portfolio securities may be limited by the
requirement for qualification as a regulated investment company that less than
30% of the Fund's annual gross income be derived from the disposition of
securities held for less than three months.
    
 
   
  Investments of the Fund in securities issued at a discount or providing for
deferred interest or payment of interest in kind are subject to special tax
rules that will affect the amount, timing and character of distributions to
shareholders. For example, with respect to securities issued at a discount, the
Fund will be required to accrue as income each year a portion of the discount
and to distribute such income each year in order to maintain its qualification
as a regulated investment company
    
 
                                       48
<PAGE>   350
 
   
and to avoid income and excise taxes. In order to generate sufficient cash to
make distributions necessary to satisfy the 90% distribution requirement and to
avoid income and excise taxes, the Fund may have to dispose of securities that
it would otherwise have continued to hold. A portion of the discount relating to
certain stripped tax-exempt obligations may constitute taxable income when
distributed to shareholders.
    
 
   
  DISTRIBUTIONS.  The Fund intends to invest in sufficient tax-exempt municipal
securities to permit payment of "exempt-interest dividends" (as defined in the
Code). Dividends paid by the Fund from the net tax-exempt interest earned from
municipal securities qualify as exempt-interest dividends if, at the close of
each quarter of its taxable year, at least 50% of the value of the total assets
of the Fund consists of municipal securities.
    
 
   
  The Tax Reform Act of 1986 (the "Tax Reform Act") may have an adverse impact
upon the Fund and its shareholders. The Tax Reform Act imposed new limitations
on the use and investment of the proceeds of state and local government bonds
and other funds, which limitations must be satisfied in order to maintain the
exclusion from gross income for interest on such bonds. The provisions of the
Tax Reform Act generally apply to bonds issued after August 15, 1986. In light
of these requirements, bond counsel qualify their opinions as to the federal tax
status of bonds issued after August 15, 1986 by making them contingent on the
issuer's future compliance with these limitations. Any failure on the part of an
issuer to comply could cause the interest on its bonds to become taxable to
investors retroactive to the date the bonds were issued.
    
 
   
  Except as provided below, exempt-interest dividends paid to shareholders
generally are not includable in the shareholders' gross income for federal
income tax purposes. The percentage of the total dividends paid by the Fund
during any taxable year that qualify as exempt-interest dividends will be the
same for all shareholders of the Fund receiving dividends during such year.
    
 
   
  The Tax Reform Act also makes interest on certain "private-activity bonds" an
item of tax preference subject to the alternative minimum tax on individuals and
corporations. The Fund invests a portion of its assets in municipal securities
subject to this provision so that a portion of its exempt-interest dividends is
an item of tax preference to the extent such dividends represent interest
received from these private-activity bonds. Accordingly, investment in the Fund
could cause shareholders to be subject to (or result in an increased liability
under) the alternative minimum tax. The Tax Reform Act also imposed per capita
volume limitations on certain private-activity bonds which could limit the
amount of such bonds available for investment by the Fund.
    
 
   
  Exempt-interest dividends are included in determining what portion, if any, of
a person's social security and railroad retirement benefits will be includable
in gross income subject to federal income tax.
    
 
                                       49
<PAGE>   351
 
   
  Although exempt-interest dividends generally may be treated by Fund
shareholders as items of interest excluded from their gross income, each
shareholder is advised to consult his tax adviser with respect to whether
exempt-interest dividends retain this exclusion if the purchaser would be
treated as a "substantial user" (or a "related person" of a substantial user) of
the facilities financed with respect to any of the tax-exempt obligations held
by the Fund, or by the Trust if it is required to qualify as a regulated
investment company as described below. "Substantial user" is defined under U.S.
Treasury Regulations to include a non-exempt person who regularly uses in his
trade or business a part of any facilities financed with the tax-exempt
obligations and whose gross revenues derived from such facilities exceed five
percent of the total revenues derived from the facilities by all users, or who
occupies more than 5% of the useable area of the facilities or for whom the
facilities or a part thereof were specifically constructed, reconstructed or
acquired. Examples of "related persons" include certain related natural persons,
affiliated corporations, a partnership and its partners and an S corporation and
its shareholders.
    
 
   
  The Omnibus Budget Reconciliation Act of 1993 included certain provisions that
requires gains on dispositions of tax-exempt securities purchased at a market
discount be treated as ordinary income to the extent of the accrued market
discount, if the securities are acquired after April 30, 1993. Such securities
were exempt from the market discount rules under prior law. Interest on
indebtedness incurred or continued by a shareholder to purchase or carry shares
of the Fund is not deductible for federal income tax purposes if the Fund
distributes exempt-interest dividends during the shareholder's taxable year. If
a shareholder receives an exempt-interest dividend with respect to any shares
and such shares are held for six months or less, any short-term capital loss on
the sale or exchange of the shares will be disallowed to the extent of the
amount of such exempt-interest dividend.
    
 
   
  While the Fund expects that a major portion of its net investment income will
constitute tax-exempt interest, a significant portion may consist of investment
company taxable income. Distributions of the Fund's net investment company
taxable income are taxable to shareholders as ordinary income to the extent of
the Fund's earnings and profits, whether paid in cash or reinvested in
additional shares. Distributions of the Fund's net capital gains ("capital gains
dividends"), if any, are taxable to shareholders as long-term capital gains
regardless of the length of time shares of the Fund have been held by such
shareholders. Interest on indebtedness which is incurred to purchase or carry
shares of a mutual fund which distributes exempt-interest dividends during the
year is not deductible for federal income tax purposes. Distributions in excess
of the Fund's earnings and profits will first reduce the adjusted tax basis of a
holder's shares and, after such adjusted tax basis is reduced to zero, will
constitute capital gains to such holder (assuming such shares are held as a
capital asset). Tax-exempt shareholders not subject to federal income tax on
their income generally will not be taxed on distributions from the Fund.
    
 
   
  Shareholders receiving distributions in the form of additional shares issued
by the Fund will be treated for federal income tax purposes as receiving a
distribution in an
    
 
                                       50
<PAGE>   352
 
   
amount equal to the fair market value of the shares received, determined as of
the distribution date. The basis of such shares will equal the fair market value
on the distribution date.
    
 
   
  The Fund will inform shareholders of the source and tax status of all
distributions promptly after the close of each calendar year. The aggregate
amount of dividends so designated cannot exceed, however, the amount of interest
exempt from tax under Section 103 of the Code received by the Fund during the
year over any amounts disallowed as deductions under Sections 265 and 171(a)(2)
of the Code. Since the percentage of dividends which are "exempt-interest"
dividends is determined on an average annual method for the fiscal year, the
percentage of income designated as tax-exempt for any particular dividend may be
substantially different from the percentage of the Fund's income that was tax
exempt during the period covered by the dividend, Fund distributions generally
will not qualify for the dividends received deduction for corporations.
    
 
   
  Although dividends generally will be treated as distributed when paid,
dividends declared in October, November or December, payable to shareholders of
record on a specified date in such month and paid during January of the
following year will be treated as having been distributed by the Fund and
received by the shareholders on the December 31 prior to the date of payment. In
addition, certain other distributions made after the close of a taxable year of
the Fund may be "spilled back" and treated as paid by the Fund (except for
purposes of the 4% excise tax) during such taxable year. In such case,
shareholders will be treated as having received such dividends in the taxable
year in which the distribution was actually made.
    
 
   
  The Fund is required, in certain circumstances, to withhold 31% of dividends
and certain other payments, including redemptions, paid to shareholders who do
not furnish to the Fund their correct taxpayer identification number (in the
case of individuals, their social security number) and certain required
certifications or who are otherwise subject to backup withholding.
    
 
   
  SALE OF SHARES.  The sale of shares (including transfers in connection with a
redemption or repurchase of shares) will be a taxable transaction for federal
income tax purposes. Selling shareholders will generally recognize gain or loss
in an amount equal to the difference between their adjusted tax basis in the
shares and the amount received. If such shares are held as a capital asset, the
gain or loss will be a capital gain or loss and will be long-term if such shares
have been held for more than one year. Any loss realized upon a taxable
disposition of shares held for six months or less will be treated as a long-term
capital loss to the extent of any capital gains dividends received with respect
to such shares. For purposes of determining whether shares have been held for
six months or less, the holding period is suspended for any periods during which
the shareholder's risk of loss is diminished as a result of holding one or more

  GENERAL.  The federal, state and local income tax discussion set forth above
is for general information only. Prospective investors should consult their
advisors regarding the specific federal tax consequences of holding and
disposing of shares, as well as the effects of state, local and foreign tax law
and any proposed tax law changes.

FUND PERFORMANCE
- ------------------------------------------------------------------------------
 
   
  From time to time advertisements and other sales materials for the Fund may
include information concerning the historical performance of the Fund. Any such
information will include the average total return of the Fund calculated on a
compounded basis for specified periods of time. Such advertisements and sales
material may also include a yield quotation as of a current period. In each
case, such total return and yield information, if any, will be calculated
pursuant to rules established by the SEC and will be computed separately for
each class of the Fund's shares. In lieu of or in addition to total return and
yield calculations, such information may include performance rankings and
similar information from independent organizations such as Lipper Analytical
Services, Inc. or nationally recognized financial publications.
    
 
   
  From time to time, the Fund may include in its sales literature and
shareholder reports a quotation of the current "distribution rate" for each
class of shares of the Fund. Distribution rate is a measure of the level of
income and short-term capital gain dividends, if any, distributed for a
specified period. Distribution rate is determined by annualizing the
distributions per share for a stated period and dividing the result by the
public offering price for the same period. It differs from yield, which is a
measure of the income actually earned by the Fund's investments, and from total
return, which is a measure of the income actually earned by, plus the effect of
any realized and unrealized appreciation or depreciation of such investments
during a stated period. Distribution rate is, therefore, not intended to be a
complete measure of the Fund's performance. Distribution rate may sometimes be
greater than yield since, for instance, it may not include the effect of
amortization of bond premiums, and may include non-recurring short-term capital
gains and premiums from futures transactions engaged in by the Fund.
Distribution rates will be computed separately for each class of the Fund's
shares.
    
 
  From time to time, the Fund may compare its performance to certain securities
and unmanaged indices which may have different risk/reward characteristics than
the Fund. Such characteristics may include, but are not limited to, tax
features, guarantees, insurance and the fluctuation of principal or return. In
addition, from time to time, the Fund may utilize sales literature that includes
hypotheticals.
 
   
  Further information about the Fund's performance is contained in the Fund's
Annual Report and the Fund's Statement of Additional Information, each of which
can be obtained without charge by calling (800) 421-5666 ((800) 421-2833 for the
hearing impaired).

DESCRIPTION OF SHARES OF THE FUND
- ------------------------------------------------------------------------------
 
  The Fund is a series of the Van Kampen American Capital Tax Free Trust, a
Delaware business trust organized as of May 10, 1995 (the "Trust"). The Fund was
originally organized in 1994 under the name Van Kampen Merritt New Jersey Tax
Free Income Fund as a sub-trust of Van Kampen Merritt Tax Free Fund, a
Massachusetts business trust. The Fund was reorganized as a series of the Trust
as of July 31, 1995. Shares of the Trust entitle their holders to one vote per
share; however, separate votes are taken by each series on matters affecting an
individual series.
 
   
  The authorized capitalization of the Fund consists of an unlimited number of
shares of beneficial interest, $0.01 par value, divided into three classes,
designated Class A Shares, Class B Shares and Class C Shares. Each class of
shares represents an interest in the same assets of the Fund and are identical
in all respects except that each class bears certain distribution expenses and
has exclusive voting rights with respect to its distribution fee. See
"Distribution and Service Plans."
    
 
   
  The Fund is permitted to issue an unlimited number of classes of shares. Each
class of shares is equal as to earnings, assets and voting privileges, except as
noted above, and each class bears the expenses related to the distribution of
its shares. There are no conversion, preemptive or other subscription rights,
except with respect to the conversion of Class B Shares and certain Class C
Shares into Class A Shares as described above. In the event of liquidation, each
of the shares of the Fund is entitled to its portion of all of the Fund's net
assets after all debt and expenses of the Fund have been paid. Since Class B
Shares and Class C Shares pay higher distribution expenses, the liquidation
proceeds to holders of Class B Shares and Class C Shares are likely to be lower
than to other shareholders.
    
 
  The Trust does not contemplate holding regular meetings of shareholders to
elect Trustees or otherwise. However, the holders of 10% or more of the
outstanding shares may by written request require a meeting to consider the
removal of Trustees by a vote of two-thirds of the shares then outstanding cast
in person or by proxy at such meeting. The Trust will assist such holders in
communicating with other shareholders of the Fund to the extent required by the
1940 Act. More detailed information concerning the Trust is set forth in the
Statement of Additional Information.

                               PROSPECTUS SUMMARY
- ------------------------------------------------------------------------------
 
THE FUND.  Van Kampen American Capital New York Tax Free Income Fund (the
"Fund") is a non-diversified mutual fund organized as a separate series of Van
Kampen American Capital Tax Free Trust (the "Trust").
 
INVESTMENT OBJECTIVE.  The Fund's investment objective is to provide investors a
high level of current income exempt from federal, New York State and New York
City income taxes, consistent with preservation of capital.
 
INVESTMENT POLICIES.  The Fund is designed for investors who are residents of
New York for tax purposes. Under normal market conditions, the Fund seeks to
achieve its investment objective by investing at least 80% of its assets in a
portfolio of New York municipal securities rated investment grade at the time of
investment. Investment grade securities are securities rated BBB or higher by
Standard & Poor's Ratings Group ("S&P"), Baa or higher by Moody's Investors
Service, Inc. ("Moody's") or an equivalent rating by another nationally
recognized statistical rating organization ("NRSRO"). Up to 20% of the Fund's
total assets may consist of New York municipal securities rated below investment
grade (but not rated lower than B- by S&P, B3 by Moody's or an equivalent rating
by another NRSRO) and unrated New York municipal securities that the Fund's
investment adviser believes are of comparable quality, which involve special
risk considerations. Up to 20% of the Fund's assets may be invested in municipal
securities that are subject to federal alternative minimum tax. See "Investment
Objective and Policies," "Municipal Securities" and "Special Considerations
Regarding the Fund."
 
INVESTMENT RESULTS.  The investment results of the Fund are shown in table of
"Financial Highlights".
 
PURCHASE OF SHARES.  Shares of the Fund are offered through Van Kampen American
Capital Distributors, Inc. (the "Distributor"), as principal underwriter, and
through selected brokers and dealers. The offering price is the net asset value
per share next determined following receipt plus a sales charge which, at the
option of the investor, may be imposed at the time of purchase or on a
contingent deferred basis. Investors may elect to purchase Class A Shares, Class
B Shares or Class C Shares, each with different sales charges and expenses. The
minimum initial investment is $500 for each class of shares and the minimum for
each subsequent investment is $25 for each class of shares (or less as described
under "Purchase of Shares"). The different classes of shares permit an investor
to choose the method of purchasing shares that is more beneficial to the
investor, taking into account the amount of the purchase, the length of time the
investor expects to hold the shares and other circumstances. See "Purchase of
Shares."
 
   
INVESTMENT ADVISER.  Van Kampen American Capital Investment Advisory Corp. (the
"Adviser") is the Fund's investment adviser.
    
 
                                        4
<PAGE>   362
 
SPECIAL RISK FACTORS.  Up to 20% of the Fund's assets may consist of New York
securities rated below investment grade (but not rated lower than B- by S&P, B3
by Moody's or an equivalent rating by another NRSRO) and unrated New York
municipal securities considered by the Adviser to be of comparable quality. In
addition, the Fund may invest up to 20% of its assets in certain derivative
securities such as inverse floaters. Investment in such lower grade New York
municipal securities and derivative securities involves significant risks.
Furthermore, under normal market conditions, the Fund will invest substantially
all of its assets in New York municipal securities, and therefore it will be
more susceptible to factors adversely affecting issuers of New York municipal
securities than a municipal securities fund that does not invest in New York
municipal securities to this degree. There can be no assurance that the Fund
will achieve its objective. See "Special Considerations Regarding the Fund."
 
   
  The foregoing is qualified in its entirety by reference to the more detailed
    
              information appearing elsewhere in this Prospectus.

    paid by the Fund as compensation for ongoing services rendered to investors.
    With respect to each class of shares, amounts in excess of 0.25%, if any,
    represent an asset based sales charge. The asset based sales charge with

  The purpose of the foregoing table is to assist an investor in understanding
the various costs and expenses that an investor in the Fund will bear directly
or indirectly. The "Example" reflects expenses based on the "Annual Fund
Operating Expenses" table as shown above carried out to future years. As Fund
assets increase, the fees waived or expenses reimbursed by the Adviser are
expected to decrease. Accordingly, it is unlikely that future expenses as
projected will remain consistent with those determined based on the "Annual Fund
Operating Expense" table. The ten year amount with respect to Class B Shares of
the Fund reflects the lower aggregate 12b-1 and service fees applicable to such
shares after conversion to Class A Shares. THE INFORMATION CONTAINED IN THE
ABOVE TABLE SHOULD NOT BE CONSIDERED A REPRESENTATION OF PAST OR FUTURE EXPENSES
AND ACTUAL EXPENSES MAY BE GREATER OR LESSER THAN THOSE SHOWN. For a more
complete description of such costs and expenses, see "Purchase of Shares,"
"Redemption of Shares," "Investment Advisory Services" and "Distribution and
Service Plans."

THE FUND
- ------------------------------------------------------------------------------
 
  Van Kampen American Capital New York Tax Free Income Fund (the "Fund") is a
non-diversified, separate series of Van Kampen American Capital Tax Free Trust
(the "Trust"), an open-end management investment company, commonly known as a
"mutual fund," organized as a Delaware business trust. Mutual funds sell their
shares to investors and invest the proceeds in a portfolio of securities. A
mutual fund allows investors to pool their money with that of other investors in
order to obtain professional investment management. Mutual funds generally make
it possible for investors to obtain greater diversification of their investments
and to simplify their recordkeeping.
 
  Van Kampen American Capital Investment Advisory Corp. (the "Adviser") provides
investment advisory and administrative services to the Fund. The Adviser and its
affiliates also act as investment adviser to other mutual funds distributed by
Van Kampen American Capital Distributors, Inc. (the "Distributor"). To obtain
prospectuses and other information on any of these other funds, please call the
telephone number on the cover page of the Prospectus.
 
- ------------------------------------------------------------------------------
INVESTMENT OBJECTIVE AND POLICIES
- ------------------------------------------------------------------------------
 
  The investment objective of the Fund is to provide investors a high level of
current income exempt from federal, New York State and New York City income
taxes, consistent with preservation of capital. The Fund's investment objective
is a fundamental policy and may not be changed without shareholder approval of
the holders of a majority of the Fund's outstanding voting securities, as
defined in the Investment Company Act of 1940, as amended (the "1940 Act"). The
Fund is designed for investors who are residents of New York for tax purposes.
An investment in the Fund may not be appropriate for all investors. The Fund is
not intended to be a complete investment program, and investors should consider
their long-term investment goals and financial needs when making an investment
decision with respect to the Fund. An investment in the Fund is intended to be a
long-term investment and should not be used as a trading vehicle.
 
  Under normal market conditions, the Fund will invest at least 80% of its total
assets in New York municipal securities rated investment grade at the time of
investment. Investment grade securities are securities rated BBB or higher by
Standard & Poor's Ratings Group ("S&P"), Baa or higher by Moody's Investors
Service, Inc. ("Moody's") or have an equivalent rating by another nationally
recognized statistical rating organization ("NRSRO") in the case of long-term
obligations, and have equivalent ratings in the case of short-term obligations.
According to published guidelines, securities rated BBB by S&P are regarded by
S&P as having an adequate capacity to pay interest and repay principal. Whereas
such securities normally exhibit adequate protection parameters, adverse
economic conditions or changing circumstances are more likely, in the opinion of
S&P, to lead
 
                                       10
<PAGE>   368
 
to a weakened capacity to pay interest and repay principal for debt in this
category than in higher rated categories. According to published guidelines,
securities rated Baa by Moody's are considered by Moody's as medium grade
obligations. Such securities are, in the opinion of Moody's, neither highly
protected nor poorly secured. Interest payments and principal security appear to
Moody's to be adequate for the present but certain protective elements may be
lacking or may be characteristically unreliable over any great length of time.
In the opinion of Moody's they lack outstanding investment characteristics and
in fact have speculative characteristics as well. The Fund's policy with respect
to ratings is not a fundamental policy, and thus may be changed by the Trustees
without shareholder approval.
 
  Up to 20% of the Fund's total assets may be invested in New York municipal
securities rated below investment grade (but not rated lower than B- by S&P, B3
by Moody's or an equivalent rating by another NRSRO) and unrated New York
municipal securities that the Adviser considers to be of comparable quality to
such securities. According to published guidelines, securities rated below
investment grade are regarded by S&P, on balance, as predominantly speculative
with respect to capacity to pay interest and repay principal in accordance with
the terms of the obligation. While in the opinion of S&P such securities will
likely have some quality and protective characteristics, these are outweighed by
large uncertainties or major risk exposures to adverse conditions. According to
published guidelines, securities rated below investment grade are regarded by
Moody's as generally lacking characteristics of a desirable investment.
Assurance of interest and principal payments or of maintenance of other terms of
the securities' contract over any long period of time may, in the opinion of
Moody's, be small. Debt securities rated below investment grade are commonly
referred to as "junk bonds." For a description of S&P's and Moody's ratings see
the Statement of Additional Information. From time to time the Fund temporarily
may also invest up to 10% of its assets in tax exempt money market funds. Such
instruments will be treated as investments in municipal securities.
 
  The Adviser will buy and sell securities for the Fund's portfolio with a view
to seeking a high level of current income exempt from federal, New York State
and New York City income taxes and will select securities which the Adviser
believes entail reasonable credit risk considered in relation to the investment
policies of the Fund. As a result, the Fund will not necessarily invest in the
highest yielding New York municipal securities permitted by its investment
policies if the Adviser determines that market risks or credit risks associated
with such investments would subject the Fund's portfolio to undue risk. The
potential for realization of capital gains resulting from possible changes in
interest rates will not be a major consideration. Other than for tax purposes,
frequency of portfolio turnover generally will not be a limiting factor if the
Fund considers it advantageous to purchase or sell securities. The Fund
anticipates that its annual portfolio turnover rate normally will be less than
200%. A high rate of portfolio turnover involves correspondingly greater
brokerage commission expenses or dealer costs than a lower rate, which expenses
and costs must be borne by the Fund and its shareholders. High portfolio
turnover
 
                                       11
<PAGE>   369
 
may also result in the realization of substantial net short-term capital gains
and any distributions resulting from such gains will be taxable. See "Tax
Status" in this Prospectus and "Investment Policies and Restrictions" in the
Statement of Additional Information.
 
  At times, conditions in the markets for New York municipal securities may, in
the Adviser's judgment, make pursuing the Fund's basic investment strategy
inconsistent with the best interests of its shareholders. At such times, the
Adviser may use alternative strategies primarily designed to reduce fluctuations
in the value of the Fund's assets. In implementing these "defensive" strategies,
the Fund may invest to a substantial degree in high-quality, short-term New York
municipal obligations. If these high-quality, short-term New York municipal
obligations are not available or, in the Adviser's judgment, do not afford
sufficient protection against adverse market conditions, the Fund may invest in
high quality municipal securities of issuers other than issuers of New York
municipal securities. Furthermore, if such high-quality municipal securities are
not available or, in the Adviser's judgment, do not afford sufficient protection
against adverse market conditions, the Fund may invest in taxable obligations.
Such taxable obligations may include: obligations of the U.S. Government, its
agencies or instrumentalities; other debt securities rated within the four
highest categories by either S&P or Moody's (or comparably rated by another
NRSRO); commercial paper rated in the highest grade by either rating service (or
comparably rated by another NRSRO); certificates of deposit and bankers'
acceptances; repurchase agreements with respect to any of the foregoing
investments; or any other fixed-income securities that the Adviser considers
consistent with such strategy. To the extent that the Fund invests a substantial
portion of its assets in municipal securities other than New York municipal
securities or in taxable securities for temporary defensive purposes, the Fund
will not be invested in a manner primarily designed to achieve a high level of
current income exempt from federal, New York State and New York City income
taxes.
 
   
  The table below sets forth the percentages of the Fund's assets invested
during the fiscal year ended December 31, 1996 in the various Moody's and S&P
rating categories and in unrated securities determined by the Adviser to be of
comparable quality. The percentages are based on the dollar-weighted average of
credit ratings

  Securities rated D are in default, and payment of interest or repayment of
principal is in arrears. Securities that are in default or with respect to which
payment of interest or repayment of principal is in arrears present special risk
considerations. The Fund may incur additional expenses to the extent that it is
required to seek recovery of interest or principal, and the Fund may be unable
to obtain full recovery thereof. See "Municipal Securities--Special
Considerations Regarding Medium and Lower Grade Municipal Securities."
    
 
   
  The portfolio composition shown in the table above reflects the allocation of
assets by the Fund during a period of relative instability in the market for
medium and lower grade securities. The percentage of the Fund's assets invested
in securities of various grades may from time to time vary substantially from
those set forth above.

MUNICIPAL SECURITIES
- ------------------------------------------------------------------------------
 
  GENERAL. Municipal securities are obligations issued by or on behalf of
states, territories or possessions of the United States, the District of
Columbia and their political subdivisions, agencies and instrumentalities, the
interest on which, in the opinion of bond counsel or other counsel to the issuer
of such securities is, at the time of issuance, exempt from federal income tax.
New York municipal securities are municipal securities the interest on which, in
the opinion of bond counsel or other counsel to the issuers of such securities,
is at the time of issuance exempt from New York State and New York City
individual income tax. Under normal market conditions, at least 80% of the
Fund's assets will be invested in New York municipal securities. The policy
stated in the foregoing sentence is a fundamental policy of the Fund and cannot
be changed without approval of the shareholders of
 
                                       13
<PAGE>   371
 
the Fund. Up to 20% of the Fund's assets may be invested in municipal securities
that are subject to the federal alternative minimum tax.
 
  The two principal classifications of municipal securities are "general
obligation" and "revenue" securities. "General obligation" securities are
secured by the issuer's pledge of its faith, credit and taxing power for the
payment of principal and interest. "Revenue" securities are usually payable only
from the revenues derived from a particular facility or class of facilities or,
in some cases, from the proceeds of a special excise tax or other specific
revenue source. Industrial development bonds are usually revenue securities, the
credit quality of which is normally directly related to the credit standing of
the industrial user involved.
 
  Within these principal classifications of municipal securities, there are a
variety of types of municipal securities, including fixed and variable rate
securities, municipal notes, municipal leases, custodial receipts, participation
certificates and derivative municipal securities the terms of which include
elements of, or are similar in effect to, certain Strategic Transactions (as
defined below) in which the Fund may engage. Variable rate securities bear rates
of interest that are adjusted periodically according to formulae intended to
reflect market rates of interest. The Fund may also invest in derivative
variable rate securities such as inverse floaters whose rates vary inversely
with changes in market rates of interest. When market rates of interest
decrease, the change in value of such securities will have a positive effect on
the net asset value of the Fund and when market rates of interest increase, the
change in value of such securities will have a negative effect on the net asset
value of the Fund. The extent of increases and decreases in the value of inverse
floaters and the corresponding change to the net asset value of the Fund
generally will be larger than comparable changes in the value of an equal
principal amount of a fixed rate municipal security having similar credit
quality, redemption provisions and maturity. The Fund will not invest more than
20% of its total assets in securities whose rates vary inversely with changes in
market rates of interest.
 
  Municipal notes include tax, revenue and bond anticipation notes of short
maturity, generally less than three years, which are issued to obtain temporary
funds for various public purposes. Municipal leases are obligations issued by
state and local governments or authorities to finance the acquisition of
equipment and facilities. Certain municipal lease obligations may include
"non-appropriation" clauses which provide that the municipality has no
obligation to make lease or installment purchase payments in future years unless
money is appropriated for such purpose on a yearly basis. Custodial receipts are
underwritten by securities dealers or banks and evidence ownership of future
interest payments, principal payments or both on certain municipal securities.
Participation certificates are obligations issued by state or local governments
or authorities to finance the acquisition of equipment and facilities. They may
represent participations in a lease, an installment purchase contract, or a
conditional sales contract. Municipal securities may not be backed by the faith,
credit and taxing power of the issuer. Other than as set forth above, there is
no limitation with respect to the amount of the
 
                                       14
<PAGE>   372
 
Fund's assets that may be invested in the foregoing types of municipal
securities. Certain of the municipal securities in which the Fund may invest
represent relatively recent innovations in the municipal securities markets and
the markets for such securities may be less developed than the market for
conventional fixed rate municipal securities. A more detailed description of the
types of municipal securities in which the Fund may invest is included in the
Statement of Additional Information.
 
  Under normal market conditions, longer term municipal securities generally
provide a higher yield than shorter term municipal securities, and therefore the
Fund generally expects to invest primarily in longer term municipal securities.
The Fund will, however, invest in shorter term municipal securities when it
believes market conditions warrant such investments. The net asset value of the
Fund will change with changes in the value of its portfolio securities. Because
the Fund will invest primarily in fixed income municipal securities, the net
asset value of the Fund can be expected to change as general levels of interest
rates fluctuate. When interest rates decline, the value of a portfolio invested
in fixed income securities generally can be expected to rise. Conversely, when
interest rates rise, the value of a portfolio invested in fixed income
securities generally can be expected to decline. The prices of longer term
municipal securities generally are more volatile with respect to changes in
interest rates than the prices of shorter term municipal securities. Volatility
may be greater during periods of general economic uncertainty.
 
  Although at least 80% of the municipal securities in which the Fund may invest
will be rated investment grade at the time of investment, municipal securities,
like other debt obligations, are subject to the risk of non-payment. The ability
of issuers of municipal securities to make timely payments of interest and
principal may be adversely impacted in general economic downturns and as
relative governmental cost burdens are allocated and reallocated among federal,
state and local governmental units. Such non-payment would result in a reduction
of income to the Fund, and could result in a reduction in the value of the
municipal securities experiencing non-payment and a potential decrease in the
net asset value of the Fund.
 
  Up to 20% of the Fund's assets may be invested in municipal securities that
are subject to the federal alternative minimum tax. The Fund may not be a
suitable investment for investors who are already subject to the federal
alternative minimum tax or who would become subject to the federal alternative
minimum tax as a result of an investment in the Fund. In addition, income earned
or deemed to be earned with respect to the Fund's Strategic Transactions, if
any, will be taxable. See "Tax Status."
 
  From time to time, proposals have been introduced before Congress that would
have the effect of reducing or eliminating the federal tax exemption on
municipal securities. If such a proposal were enacted, the ability of the Fund
to pay tax exempt interest dividends might be adversely affected.
 
                                       15
<PAGE>   373
 
  LOWER GRADE MUNICIPAL SECURITIES. The Fund may invest up to 20% of its total
assets in New York municipal securities rated below investment grade (but not
rated lower than B- by S&P or B3 by Moody's or an equivalent rating by another
NRSRO) or in unrated New York municipal securities considered by the Adviser to
be of comparable quality to such securities. Higher yields are generally
available from municipal securities of such grade. With respect to such 20% of
the Fund's total assets, the Fund has not established any limit on the
percentage of its portfolio which may be invested in securities in any one
rating category or comparable unrated securities.
 
  Investors should carefully consider the risks of owning shares of an
investment company which invests in lower grade municipal securities before
making an investment in the Fund. The higher yield on certain securities held by
the Fund reflects a greater possibility that the financial condition of the
issuer, or adverse changes in general economic conditions, or both, may impair
the ability of the issuer to make payments of income and principal. See "Special
Considerations Regarding the Fund."
 
  The Adviser seeks to minimize the risks involved in investing in lower grade
municipal securities through diversification and careful investment analysis. To
the extent that there is no established retail market for some of the lower
grade municipal securities in which the Fund may invest, trading in such
securities may be relatively inactive. The Adviser is responsible for
determining the net asset value of the Fund, subject to the supervision of the
Board of Trustees of the Trust. During periods of reduced market liquidity and
in the absence of readily available market quotations for lower grade municipal
securities held in the Fund's portfolio, the ability of the Adviser to value the
Fund's securities becomes more difficult and the Adviser's use of judgment may
play a greater role in the valuation of the Fund's securities due to the reduced
availability of reliable objective data. The effects of adverse publicity and
investor perceptions may be more pronounced for securities for which no
established retail market exists as compared with the effects on securities for
which such a market does exist. Further, the Fund may have more difficulty
selling such securities in a timely manner and at their stated value than would
be the case for securities for which an established retail market does exist.
See "Special Considerations Regarding the Fund."
 
- ------------------------------------------------------------------------------
INVESTMENT PRACTICES
- ------------------------------------------------------------------------------
 
  In connection with the investment policies described above, the Fund also may
engage in strategic transactions and purchase and sell securities on a "when
issued" and "delayed delivery" basis. These investments entail risks. Strategic
transactions generally will not be treated as investments in New York municipal
securities for purposes of the Fund's 80% investment policy with respect
thereto.
 
  STRATEGIC TRANSACTIONS. The Fund may purchase and sell derivative instruments
such as exchange-listed and over-the-counter put and call options on securities,
 
                                       16
<PAGE>   374
 
financial futures, fixed-income indices and other financial instruments,
purchase and sell financial futures contracts and enter into various interest
rate transactions such as swaps, caps, floors or collars. Collectively, all of
the above are referred to as "Strategic Transactions." Strategic Transactions
may be used to attempt to protect against possible changes in the market value
of securities held in or to be purchased for the Fund's portfolio resulting from
securities markets, to protect the Fund's unrealized gains in the value of its
portfolio securities, to facilitate the sale of such securities for investment
purposes, to manage the effective maturity or duration of the Fund's portfolio,
or to establish a position in the derivatives markets as a temporary substitute
for purchasing or selling particular securities. Any or all of these investment
techniques may be used at any time and there is no particular strategy that
dictates the use of one technique rather than another, as use of any Strategic
Transaction is a function of numerous variables including market conditions. The
ability of the Fund to utilize these Strategic Transactions successfully will
depend on the Adviser's ability to predict pertinent market movements, which
cannot be assured. The Fund will comply with applicable regulatory requirements
when implementing these strategies, techniques and instruments.
 
  Strategic Transactions have risks associated with them including possible
default by the other party to the transaction, illiquidity and, to the extent
the Adviser's view as to certain market movements is incorrect, the risk that
the use of such Strategic Transactions could result in losses greater than if
they had not been used. Use of put and call options may result in losses to the
Fund, force the sale of portfolio securities at inopportune times or for prices
other than at current market values, limit the amount of appreciation the Fund
can realize on its investments or cause the Fund to hold a security it might
otherwise sell. The use of options and futures transactions entails certain
other risks. In particular, the variable degree of correlation between price
movements of futures contracts and price movements in the related portfolio
position of the Fund creates the possibility that losses on the hedging
instrument may be greater than gains in the value of the Fund's position. In
addition, futures and options markets may not be liquid in all circumstances and
certain over-the-counter options may have no markets. As a result, in certain
markets, the Fund might not be able to close out a transaction without incurring
substantial losses, if at all. Although the contemplated use of these futures
contracts and options thereon should tend to minimize the risk of loss due to a
decline in the value of the hedged position, at the same time they tend to limit
any potential gain which might result from an increase in value of such
position. Finally, the daily variation margin requirements for futures contracts
would create a greater ongoing potential financial risk than would purchases of
options, where the exposure is limited to the cost of the initial premium.
Losses resulting from the use of Strategic Transactions would reduce net asset
value, and possibly income, and such losses can be greater than if the Strategic
Transactions had not been utilized. The Strategic Transactions that the Fund may
use and some of their risks are described more fully in the Fund's Statement of
Additional Information.
 
                                       17
<PAGE>   375
 
  Income earned or deemed to be earned, by the Fund from, among other things,
its Strategic Transactions and temporary defensive strategies, if any, generally
will be taxable income of the Fund. See "Tax Status."
 
   
  "WHEN ISSUED" AND "DELAYED DELIVERY" TRANSACTIONS.  The Fund may also purchase
and sell municipal securities on a "when issued" and "delayed delivery" basis.
No income accrues to the Fund on municipal securities in connection with such
transactions prior to the date the Fund actually takes delivery of such
securities. These transactions are subject to market fluctuation; the value of
the municipal securities at delivery may be more or less than their purchase
price, and yields generally available on municipal securities when delivery
occurs may be higher than yields on the municipal securities obtained pursuant
to such transactions. Because the Fund relies on the buyer or seller, as the
case may be, to consummate the transaction, failure by the other party to
complete the transaction may result in the Fund missing the opportunity of
obtaining a price or yield considered to be advantageous. When the Fund is the
buyer in such a transaction, however, it will maintain, in a segregated account
with its custodian, cash or liquid securities having an aggregate value equal to
the amount of such purchase commitments until payment is made. The Fund will
make commitments to purchase municipal securities on such basis only with the
intention of actually acquiring these securities, but the Fund may sell such
securities prior to the settlement date if such sale is considered to be
advisable. To the extent the Fund engages in "when issued" and "delayed
delivery" transactions, it will do so for the purpose of acquiring securities
for the Fund's portfolio consistent with the Fund's investment objectives and
policies and not for the purposes of investment leverage. No specific limitation
exists as to the percentage of the Fund's assets which may be used to acquire
securities on a "when issued" or "delayed delivery" basis.
    
 
  RESTRICTED AND ILLIQUID SECURITIES. The Fund may invest up to 15% of its net
assets in illiquid securities including securities the disposition of which is
subject to substantial legal or contractual restrictions on resale and
securities that are not readily marketable. The sale of restricted and illiquid
securities often requires more time and results in higher brokerage charges or
dealer discounts and other selling expenses than does the sale of securities
eligible for trading on national securities exchanges or in the over-the-counter
markets. Restricted securities may sell at a price lower than similar securities
that are not subject to restrictions on resale.
 
  OTHER PRACTICES. The Fund may borrow amounts up to 5% of its net assets in
order to pay for redemptions when liquidation of portfolio securities is
considered disadvantageous or inconvenient and may pledge up to 10% of its net
assets to secure such borrowings.
 
  Under normal market conditions, the Fund will invest substantially all of its
assets in New York municipal securities. The Fund generally will not invest more
than 25% of its total assets in any industry. Governmental issuers of municipal
securities are not considered part of any "industry." However, municipal
securities
 
                                       18
<PAGE>   376
 
backed only by the assets and revenues of nongovernmental users may for this
purpose be deemed to be issued by such nongovernmental users, and the 25%
limitation would apply to such obligations. It is therefore possible that the
Fund may invest more than 25% of its assets in a broader segment of the
municipal securities market, such as revenue obligations of hospitals and other
health care facilities, housing agency revenue obligations, or airport revenue
obligations if the Adviser determines that the yields available from obligations
in a particular segment of the market justifies the additional risks associated
with a large investment in such segment. Although such obligations could be
supported by the credit of governmental users, or by the credit of
nongovernmental users engaged in a number of industries, economic, business,
political and other developments generally affecting the revenues of such users
(for example, proposed legislation or pending court decisions affecting the
financing of such projects and market factors affecting the demand for their
services or products) may have a general adverse effect on all municipal
securities in such a market segment.
 
  From time to time, the Fund's investments may include securities as to which
the Fund, by itself or together with other funds or accounts managed by the
Adviser, holds a major portion or all of an issue of New York municipal
securities. Because there may be relatively few potential purchasers for such
investments and, in some cases, there may be contractual restrictions on
resales, the Fund may find it more difficult to sell such securities at a time
when the Adviser believes it is advisable to do so.
 
  INVESTMENT RESTRICTIONS. The Fund is subject to certain investment
restrictions which constitute fundamental policies. Fundamental policies cannot
be changed without the approval of the holders of a majority of the Fund's
outstanding voting securities, as defined in the 1940 Act. See "Investment
Policies and Restrictions" in the Statement of Additional Information.
 
  PORTFOLIO TRANSACTIONS AND BROKERAGE ALLOCATION. 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 prices and any
brokerage commissions. The income securities in which the Fund invests are
traded principally in the over-the-counter market. In the over-the-counter
market, securities are generally traded on a net basis with dealers acting as
principal for their own accounts without a stated commission, although the price
of the security usually includes a mark-up to the dealer. Securities purchased
in underwritten offerings generally include, in the price, a fixed amount of
compensation for the managers, underwriters and dealers. The Fund may also
purchase certain money market instruments directly from an issuer, in which case
no commissions or discounts are paid. Purchases and sales of bonds on a stock
exchange are effected through brokers who charge a commission for their
services.
 
  The Adviser is responsible for effecting securities transactions of the Fund
and will do so in a manner deemed fair and reasonable to shareholders of the
Fund and not according to any formula. The Adviser's primary considerations in
selecting the
 
                                       19
<PAGE>   377
 
manner of executing securities transactions for the Fund will be prompt
execution of orders, the size and breadth of the market for the security, the
reliability, integrity and financial condition and execution capability of the
firm, the size of and difficulty in executing the order, and the best net price.
There are many instances when, in the judgment of the Adviser, more than one
firm can offer comparable execution services. In selecting among such firms,
consideration is given to those firms which supply research and other services
in addition to execution services. However, it is not the policy of the Adviser,
absent special circumstances, to pay higher commissions to a firm because it has
supplied such services.
 
  In effecting purchases and sales of the Fund's portfolio securities, the
Adviser and the Fund may place orders with and pay brokerage commissions to
brokers, including brokers which may be affiliated with the Fund, the Adviser
and the Distributor or dealers participating in the offering of the Fund's
shares. In addition, in selecting among firms to handle a particular
transaction, the Adviser and the Fund may take into account whether the firm has
sold or is selling shares of the Fund. See "Portfolio Transactions and Brokerage
Allocation" in the Statement of Additional Information for more information.
 
- ------------------------------------------------------------------------------
SPECIAL CONSIDERATIONS REGARDING THE FUND
- ------------------------------------------------------------------------------
 
  GENERAL. In normal circumstances, the Fund may invest up to 20% of its total
assets in New York municipal securities rated below investment grade (but not
rated lower than B- by S&P, B3 by Moody's or an equivalent rating by another
NRSRO) or in unrated New York municipal securities considered by the Adviser to
be of comparable quality to such securities. Investment in such lower grade
municipal securities involves special risks as compared with investment in
higher grade municipal securities. The market for lower grade municipal
securities is considered to be less liquid than the market for investment grade
municipal securities which may adversely affect the ability of the Fund to
dispose of such securities in a timely manner at a price which reflects the
value of such security in the Adviser's judgement. The market price for less
liquid securities tends to be more volatile than the market price for more
liquid securities. Illiquid securities and the absence of readily available
market quotations with respect thereto may make the Adviser's valuation of such
securities more difficult, and the Adviser's judgement may play a greater role
in the valuation of the Fund's securities. Lower grade municipal securities
generally involve greater credit risk than higher grade municipal securities and
are more sensitive to adverse economic changes, significant increases in
interest rates and individual issuer developments. Because issuers of lower
grade municipal securities frequently choose not to seek a rating of their
municipal securities, the Fund will rely more heavily on the Adviser's ability
to determine the relative investment quality of such securities than if the Fund
invested exclusively in higher grade municipal securities. The Fund may, if
deemed appropriate by the Adviser, retain a security whose rating has been
downgraded below B- by S&P, below B3 by Moody's or an equivalent rating by
another
 
                                       20
<PAGE>   378
 
NRSRO, or whose rating has been withdrawn. More detailed information concerning
the risks associated with instruments in lower grade municipal securities is
included in the Fund's Statement of Additional Information.
 
  The Fund may invest up to 20% of its total assets in derivative variable rate
securities such as inverse floaters whose rates of interest vary inversely with
changes in market rates of interest. When market rates of interest decrease, the
change in value of such securities will have a positive effect on the net asset
value of the Fund and when market rates of interest increase, the change in
value of such securities will have a negative effect on the net asset value of
the Fund. Investment in such securities involve special risks as compared to a
fixed rate municipal security. The extent of increases and decreases in the
value of inverse floaters and the corresponding change to per share net asset
value of the Fund generally will be larger than comparable changes in the value
of an equal principal amount of a fixed rate municipal security having similar
credit quality, redemption provisions and maturity. The markets for inverse
variable rate securities may be less developed than the market for conventional
fixed rate municipal securities.
 
  SPECIAL CONSIDERATIONS REGARDING NEW YORK MUNICIPAL SECURITIES. Investors
should be aware of certain factors that might affect the financial condition of
the issuers of New York municipal securities. The State of New York has
historically been one of the wealthiest states in the nation. For decades,
however, the economy of the State of New York has grown more slowly than that of
the nation as a whole, and the result has been a gradual erosion of the State's
relative economic affluence. New York City, for example, has faced greater
competition as other major cities have developed financial and business
capabilities which make them less dependent on the specialized services
traditionally available almost exclusively in New York City.
 
  The State of New York has for many years had a very high state and local tax
burden. The burden of state and local taxation, in combination with the many
other causes of regional economic dislocations, has contributed to the decisions
of some businesses and individuals to relocate outside, or not locate within,
the State of New York.
 
  There can be no assurance that the State of New York and its political
subdivisions will not face substantial potential budget gaps in future years
resulting from a significant disparity between tax revenues projected from a
lower recurring receipts base and the spending required to maintain programs at
current levels. To address any potential budgetary imbalance, the State of New
York and such subdivisions may need to take significant actions to align
recurring receipts and disbursements in future fiscal years.
 
  Although revenue obligations of the State of New York or its political
subdivisions may be payable from a specific project or source, including lease
rentals, there can be no assurance that future economic difficulties and the
resulting impact on State and local government finances will not adversely
affect the market value of
 
                                       21
<PAGE>   379
 
the portfolio of the Fund or the ability of the respective obligors to make
timely payments of principal and interest on such obligations.
 
  More detailed information concerning New York municipal securities and the
State of New York is included in the Statement at Additional Information.

  ADVISORY AGREEMENT.  The business and affairs of the Fund will be managed
under the direction of the Board of Trustees of the Trust, of which the Fund is
a separate series. Subject to their authority, the Adviser and the respective
officers of the Fund will supervise and implement the Fund's investment

  Under its investment advisory agreement with the Adviser, the Fund has agreed
to assume and pay the charges and expenses of the Fund's operation, including
the compensation of the Trustees of the Trust (other than those who are
affiliated persons, as defined in the 1940 Act, of the Adviser, the Distributor
or Van Kampen American Capital), the charges and expenses of independent
accountants, legal counsel, transfer agent (ACCESS Investor Services, Inc.
("ACCESS"), a wholly-owned subsidiary of Van Kampen American Capital), or

securities), costs of calculating net asset value, costs of acquiring and
disposing of portfolio securities, interest (if any) on obligations incurred by
the Fund, costs of share certificates, membership dues in the Investment Company
Institute or any similar organization, reports and notices to shareholders,
costs of registering shares of the Fund under the federal securities laws,
miscellaneous expenses and all taxes and fees to federal, state or other
governmental agencies. The Adviser reserves the right in its sole discretion
from time-to-time to waive all or a portion of its management fee or to
reimburse the Fund for all or a portion of its other expenses.
    
 
   
  PERSONAL INVESTING POLICIES. The Fund and the Adviser have adopted Codes of
Ethics designed to recognize the fiduciary relationship between the Fund and the
Adviser and its employees. The Codes permit directors, trustees, officers and
employees to buy and sell securities for their personal accounts subject to
certain restrictions. Persons with access to certain sensitive information are
subject to preclearance and other procedures designed to prevent conflicts of
interest.
    
 
  PORTFOLIO MANAGEMENT.  David C. Johnson, a Senior Vice President of the
Adviser, supervises the Adviser's municipal securities practice area and
coordinates the Adviser's investment policy regarding such securities. Mr.
Johnson has been employed by the Adviser since April 1989. Dennis S. Pietrzak, a
Vice President of the Adviser, has been primarily responsible for the day-to-day
management of the Fund's portfolio since August 1995. Mr. Pietrzak has been

Pietrzak was employed by Merrill Lynch where he was in charge of municipal
underwriting and trading in Merrill Lynch's midwest region.

- ------------------------------------------------------------------------------
ALTERNATIVE SALES ARRANGEMENTS
- ------------------------------------------------------------------------------
 
  The Alternative Sales Arrangements permit an investor to choose the method of
purchasing shares that is more beneficial to the investor, taking into account
the amount of the purchase, the length of time the investor expects to hold the
shares, whether the investor wishes to receive dividends in cash or to reinvest
them in additional shares of the Fund, and other circumstances. Investors should
consider such factors together with the amount of sales charges and accumulated
distribution and service fees with respect to each class of shares that may be
incurred over the anticipated duration of their investment in the Fund.
 
  The Fund offers three classes of shares, designated Class A Shares, Class B
Shares and Class C Shares. Shares of each class are offered at a price equal to
their net asset value per share plus a sales charge which, at the election of
the purchaser, may be imposed (a) at the time of purchase ("Class A Shares") or
(b) on a contingent deferred basis (Class A Share accounts over $1 million,
"Class B Shares" and "Class C Shares"). Class A Share accounts over $1 million
or otherwise subject to a contingent deferred sales charge ("CDSC"), Class B
Shares and Class C Shares sometimes are referred to herein collectively as
"Contingent Deferred Sales Charge Shares" or "CDSC Shares."
 
  The minimum initial investment with respect to each class of shares is $500.
The minimum subsequent investment with respect to each class of shares is $25.
It is presently the policy of the Distributor not to accept any order for Class
B Shares in an amount of $500,000 or more and not to accept any order for Class
C Shares in an amount of $1 million or more because it ordinarily will be more
advantageous for an investor making such an investment to purchase Class A
Shares.
 
  An investor should carefully consider the sales charges applicable to each
class of shares and the estimated period of their investment to determine which
class of shares is more beneficial for the investor to purchase. For example,
investors who would qualify for a significant purchase price discount from the
maximum sales charge on Class A Shares may determine that payment of such a
reduced front-end sales charge is superior to electing to purchase Class B
Shares or Class C Shares, each with no front-end sales charge but subject to a
CDSC and a higher aggregate distribution and service fee. However, because
initial sales charges are deducted at the time of purchase of Class A Share
accounts under $1 million, a purchaser of such Class A Shares would not have all
of his or her funds invested initially and, therefore, would initially own fewer
shares than if Class B Shares or Class C Shares had been purchased. On the other
hand, an investor whose purchase would not qualify for price discounts
applicable to Class A Shares and intends to remain invested until after the
expiration of the applicable CDSC may wish to defer the sales charge and have
all his or her funds initially invested in Class B Shares or Class C Shares. If
such an investor anticipates that he or she will redeem such shares prior to the
expiration of the CDSC period applicable to Class B Shares, the
 
                                       24
<PAGE>   382
 
investor may wish to acquire Class C Shares. Investors must weigh the benefits
of deferring the sales charge and having all of their funds invested against the
higher aggregate distribution and service fee applicable to Class B Shares and
Class C Shares (discussed below).
 
  Each class of shares represents an interest in the same portfolio of
investments of the Fund and has the same rights, except each class of shares (i)
bears those distribution fees, service fees and administrative expenses
applicable to the respective class of shares as a result of its sales
arrangements, (ii) has exclusive voting rights with respect to those provisions
of the Fund's Rule 12b-1 distribution plan which relate only to such class and
(iii) has a different exchange privilege. Generally, a class of shares subject
to a higher ongoing distribution and service fee or subject to the conversion
feature will have a higher expense ratio and pay lower dividends than a class of
shares subject to a lower ongoing distribution and service fee or not subject to
the conversion feature. The per share net asset values of the different classes
of shares are expected to be substantially the same; from time to time, however,
the per share net asset values of the classes may differ. The net asset value
per share of each class of shares of the Fund will be determined as described in
this Prospectus under "Purchase of Shares -- Net Asset Value."
 
   
  The administrative expenses that may be allocated to a specific class of
shares may consist of (i) ACCESS' expenses attributable to a specific class of
shares, which expenses typically will be higher with respect to classes of
shares subject to the conversion feature; (ii) printing and postage expenses
related to preparing and distributing materials such as shareholder reports,
prospectuses and proxy statements to current shareholders of a specific class;
(iii) Securities and Exchange Commission (the "SEC") registration fees incurred
by a class of shares; (iv) the expense of administrative personnel and services
as required to support the shareholders of a specific class; (v) Trustees' fees
or expense incurred as a result of issues relating to one class of shares; (vi)
accounting expenses relating solely to one class of shares; and (vii) any other
incremental expenses subsequently identified that should be properly allocated
to one or more classes of shares. All such expenses incurred by a class will be
borne on a pro rata basis by the outstanding shares of such class. All
allocations of administrative expenses to a particular class of shares will be
limited to the extent necessary to preserve the Fund's qualification as a
regulated investment company under the Internal Revenue Code of 1986, as amended
(the "Code").
    
 
- ------------------------------------------------------------------------------
PURCHASE OF SHARES
- ------------------------------------------------------------------------------
 
   
  The Fund offers three classes of shares to the public on a continuous basis
through the Distributor, as principal underwriter, which is located at One
Parkview Plaza, Oakbrook Terrace, Illinois 60181. Shares also are offered
through members of the National Association of Securities Dealers, Inc. ("NASD")
acting as securities dealers ("dealers") and through NASD members acting as
brokers for
    
 
                                       25
<PAGE>   383
 
investors ("brokers") or eligible non-NASD members acting as agents for
investors ("financial intermediaries"). The Fund reserves the right to suspend
or terminate the continuous public offering of its shares at any time and
without prior notice.
 
  The Fund's shares are offered at the net asset value per share next computed
after an investor places an order to purchase directly with the investor's
broker, dealer or financial intermediary or directly with the Distributor plus
any applicable sales charge. Sales personnel or brokers, dealers and financial
intermediaries distributing the Fund's shares may receive different compensation
for selling different classes of shares. It is the responsibility of the
investor's broker, dealer or financial intermediary to transmit the order to the
Distributor. Because the Fund generally will determine net asset value once each
business day as of the close of business, purchase orders placed through an
investor's broker, dealer or financial intermediary must be transmitted to the
Distributor by such broker, dealer or financial intermediary prior to such time
in order for the investor's order to be fulfilled on the basis of the net asset
value to be determined that day. Any change in the purchase price due to the
failure of the Distributor to receive a purchase order prior to such time must
be settled between the investor and the broker, dealer or financial intermediary
submitting the order.
 
   
  The Distributor may from time to time implement programs under which a broker,
dealer or financial intermediary's sales force may be eligible to win nominal
awards for certain sales efforts or under which the Distributor will reallow to
any broker, dealer or financial intermediary that sponsors sales contests or
recognition programs conforming to criteria established by the Distributor, or
participates in sales programs sponsored by the Distributor, an amount not
exceeding the total applicable sales charges on the sales generated by the
broker, dealer or financial intermediary at the public offering price during
such programs. Other programs provide, among other things and subject to certain
conditions, for certain favorable distribution arrangements for shares of the
Fund. Also, the Distributor in its discretion may from time to time, pursuant to
objective criteria established by it, pay fees to, and sponsor business seminars
for, qualifying brokers, dealers or financial intermediaries for certain
services or activities which are primarily intended to result in sales of shares
of the Fund. Fees may include payment for travel expenses, including lodging,
incurred in connection with trips taken by invited registered representatives
and members of their families to locations within or outside of the United
States for meetings or seminars of a business nature. In some instances
additional compensation or promotional incentives may be offered to brokers,
dealers or Financial intermediaries that have sold or may sell significant
amounts of shares during specified periods of time. The Distributor may provide
additional compensation to Edward D. Jones & Co. or an affiliate thereof based
on a combination of its sales of shares and increases in assets under
management. Such payments to brokers, dealers and financial intermediaries for
sales contests, other sales programs and seminars are made by the Distributor
out of its own assets and not out of the assets of the Fund. Such fees paid for
such services and activities with respect to the Fund will not exceed in the
aggregate 1.25% of the average total daily
    
 
                                       26
<PAGE>   384
 
   
net assets of the Fund on an annual basis. These programs will not change the
price an investor pays for shares or the amount that the Fund will receive from
such sale.
    
 
CLASS A SHARES
 
  The public offering price of Class A Shares is equal to the net asset value
per share plus an initial sales charge which is a variable percentage of the
offering price depending upon the amount of the sale. The table below shows
total sales charges and dealer concessions reallowed to dealers and agency
commissions paid to brokers with respect to sales of Class A Shares. The sales
charge is allocated between the investor's broker, dealer or financial
intermediary and the Distributor. As indicated previously, at the discretion of
the Distributor, the entire sales charge may be reallowed to such broker, dealer
or financial intermediary. The staff of the SEC has taken the position that
dealers who receive 90% or more of the sales charge may be deemed to be
"underwriters" as that term is defined in the Securities Act of 1933, as
amended.

  * No sales charge is payable at the time of purchase on investments of $1
    million or more, although for such investments the Fund imposes a CDSC of
    1.00% on redemptions made within one year of the purchase. A commission
    will be paid to brokers, dealers or financial intermediaries who initiate
    and are responsible for purchases of $1 million or more as follows: 1.00%
    on sales to $2 million, plus 0.80% on the next $1 million and 0.50% on the
    excess over $3 million. See "Purchase of Shares--Deferred Sales Charge
    Alternatives" for additional information with respect to CDSCs.
    
 
QUANTITY DISCOUNTS
 
  Investors purchasing Class A Shares may, under certain circumstances, be
entitled to pay reduced sales charges. The circumstances under which such
investors may pay reduced sales charges are described below.
 
  Investors, or their brokers, dealers or financial intermediaries, must notify
the Fund whenever a quantity discount is applicable to purchases. Upon such
notification, an investor will receive the lowest applicable sales charge.
Quantity discounts
 
                                       27
<PAGE>   385
 
may be modified or terminated at any time. For more information about quantity
discounts, investors should contact their broker, dealer or financial
intermediary or the Distributor.
 
   
  A person eligible for a reduced sales charge includes an individual, their
spouse and children under 21 years of age and any corporation, partnership or
sole proprietorship which is 100% owned, either alone or in combination, by any
of the foregoing; a trustee or other fiduciary of a single trust estate or a
single fiduciary account; or a "company" as defined is section 2(a)(8) of the
1940 Act.
    
 
   
  As used herein, "Participating Funds" refers to all open-end investment
companies advised by the Adviser or Van Kampen American Capital Asset
Management, Inc. and distributed by the Distributor. Additional Funds may be
added from time to time as determined by the Fund's Board of Trustees as
Participating Funds.
    
 
   
  VOLUME DISCOUNTS. The size of investment shown in the preceding sales charge
table applies to the total dollar amount being invested by any person at any one
time in Class A Shares of the Fund, or in any combination of shares of the Fund
and shares of other Participating Funds, although other Participating Funds may
have different sales charges.
    
 
   
  CUMULATIVE PURCHASE DISCOUNT. The size of investment shown in the preceding
sales charge table may also be determined by combining the amount being invested
in Class A Shares of the Fund with other shares of the Fund and shares of
Participating Funds, plus the current offering price of all shares of the Fund
and other Participating Funds which have been previously purchased and are still
owned.
    
 
   
  LETTER OF INTENT. A Letter of Intent provides an opportunity for an investor
to obtain a reduced sales charge by aggregating the amount being invested over a
13-month period to determine the sales charge as outlined in the preceding sales
charge table. The size of investment shown in the preceding table includes the
amount of intended purchases of Class A Shares of the Fund with other shares of
the Fund and shares of the Participating Funds plus the value of all shares of
the Fund and other Participating Funds previously purchased during such 13-month
period and still owned. An investor may elect to compute the 13-month period
starting up to 90 days before the date of execution of a Letter of Intent. Each
investment made during the period receives the reduced sales charge applicable
to the total amount of the investment goal. If trades not initially made under a
Letter of Intent subsequently qualify for a lower sales charge through the
90-day back-dating provision, an adjustment will be made at the expiration of
the Letter of Intent to give effect to the lower charge. If the goal is not
achieved within the 13-month period, the investor must pay the difference
between the sales charge applicable to the purchases made and the sales charges
previously paid. When an investor signs a Letter of Intent, shares equal to at
least 5% of the total purchase amount of the level selected will be restricted
from sale or redemption by the
    
 
                                       28
<PAGE>   386
 
investor until the Letter of Intent is satisfied or any additional sales charges
have been paid; if the Letter of Intent is not satisfied by the investor and any
additional sales charges are not paid, sufficient restricted shares will be
redeemed by the Fund to pay such charges. Additional information is contained in
the application accompanying this Prospectus.
 
OTHER PURCHASE PROGRAMS
 
   
  Purchasers of Class A Shares may be entitled to reduced initial sales charges
in connection with unit investment trust reinvestment programs and purchases by
registered representatives of selling firms or purchases by persons affiliated
with the Fund or the Distributor. The Fund reserves the right to modify or
terminate these arrangements at any time.
    
 
  UNIT INVESTMENT TRUST REINVESTMENT PROGRAMS. The Fund permits unitholders of
unit investment trusts to reinvest distributions from such trusts in Class A
Shares of the Fund at net asset value with no minimum initial or subsequent
investment requirement if the administrator of an investor's unit investment
trust program meets certain uniform criteria relating to cost savings by the
Fund and the Distributor. The total sales charge for all other investments made
from unit trust distributions will be 1.00% of the offering price (1.01% of net
asset value). Of this amount, the Distributor will pay to the broker, dealer or
financial intermediary, if any, through which such participation in the
qualifying program was initiated 0.50% of the offering price as a dealer
concession or agency commission. Persons desiring more information with respect
to this program, including the applicable terms and conditions thereof, should
contact their broker, dealer, financial intermediary or the Distributor.
 
   
  The administrator of such a unit investment trust must have an agreement with
the Distributor pursuant to which the administrator will (1) submit a single
bulk order and make payment with a single remittance for all investments in the
Fund during each distribution period by all investors who choose to invest in
the Fund through the program and (2) provide ACCESS with appropriate backup data
for each participating investor in a computerized format fully compatible with
ACCESS' processing system.
    
 
   
  As further requirements for obtaining these special benefits, the Fund also
requires that all dividends and other distributions by the Fund be reinvested in
additional shares without any systematic withdrawal program. There will be no
minimum for reinvestments from unit investment trusts. The Fund will send
account activity statements to such participants on a monthly basis only, even
if their investments are made more frequently. The Fund reserves the right to
modify or terminate this program at any time.
    
 
  NAV PURCHASE OPTIONS. Class A Shares of the Fund may be purchased at net asset
value, upon written assurance that the purchase is made for investment
 
                                       29

  (3) Directors, officers, employees and registered representatives of financial
      institutions that have a selling group agreement with the Distributor and
      their spouses and children under 21 years of age when purchasing for any
      accounts they beneficially own, or, in the case of any such financial
      institution, when purchasing for retirement plans for such institution's
      employees.
    
 
   
  (4) Registered investment advisers, trust companies and bank trust departments
      investing on their own behalf or on behalf of their clients provided that
      the aggregate amount invested in Class A Shares of the Fund alone, or any
      combination of shares of the Fund and shares of other Participating Funds
      as described herein under "Purchase of Shares -- Class A Shares --
      Quantity Discounts," during the 13-month period commencing with the first
      investment pursuant hereto equals at least $1 million. The Distributor may
      pay brokers, dealers or financial intermediaries through which purchases
      are made an amount up to 0.50% of the amount invested, over a 12-month
      period following such transaction.
    
 
   
  (5) Trustees and other fiduciaries purchasing shares for retirement plans of
      organizations with retirement plan assets of $3 million or more and which
      invest in multiple fund families through national wirehouse alliance

      financial intermediary has a separate agreement with the Distributor.
 
  (7) Investors purchasing shares of the Fund with redemption proceeds from
      other mutual fund complexes on which the investor has paid a front-end
      sales charge or was subject to a deferred sales charge, whether or not
      paid, if such redemption has occurred no more than 30 days prior to such
      purchase.
 
   
  (8) Trusts created under pension, profit sharing or other employee benefit
      plans qualified under Section 401(a) of the Code, or custodial accounts
      held by a bank created pursuant to Section 403(b) of the Code and
      sponsored by non-profit organizations defined under Section 501(c)(3) of
      the Code and assets held by an employer or trustee in connection with an
      eligible deferred compensation plan under Section 457 of the Code. Such
      plans will qualify for purchases at net asset value provided, for plans
      initially establishing
    
 
                                       30
<PAGE>   388
 
   
      accounts with the Distributor in the Participating Funds after February 1,
      1997, that (1) the initial amount invested in the Participating Funds is
      at least $500,000 or (2) such shares are purchased by an employer
      sponsored plan with more than 100 eligible employees. Such plans that have
      been established with a Participating Fund or have received proposals from
      the Distributor prior to February 1, 1997 based on net asset value
      purchase privileges previously in effect will be qualified to purchase
      shares of the Participating Funds at net asset value for accounts
      established on or before May 1, 1997. Section 403(b) and similar accounts
      for which Van Kampen American Capital Trust Company served as custodian
      will not be eligible for net asset value purchases based on the aggregate
      investment made by the plan or the number of eligible employees, except
      under certain uniform criteria established by the Distributor from time to
      time. Prior to February 1, 1997, a commission will be paid to authorized
      dealers who initiate and are responsible for such purchases within a
      rolling twelve-month period as follows: 1.00% on sales to $5 million, plus
      0.50% on the next $5 million and 0.25% on the excess over $10 million. For
      purchases on February 1, 1997 and thereafter, a commission will be paid as
      follows: 1.00% on sales to $2 million, plus 0.80% on the next $1 million,
      plus 0.50% on the next $47 million and 0.25% on the excess over $50
      million.
    
 
   
  (9) Individuals who are members of a "qualified group". For this purpose, a
      qualified group is one which (i) has been in existence for more than six
      months, (ii) has a purpose other than to acquire shares of the Fund or
      similar investments, (iii) has given and continues to give its endorsement
      or authorization, on behalf of the group, for purchase of shares of the
      Fund and other Participating Funds, (iv) has a membership that the
      authorized dealer can certify as to the group's members and (v) satisfies
      other uniform criteria established by the Distributor for the purpose of
      realizing economics of scale in distributing such shares. A qualified
      group does not include one whose sole organizational nexus, for example,
      is that its participants are credit card holders of the same institution,
      policy holders of an insurance company, customers of a bank or
      broker-dealer, clients of an investment adviser or other similar groups.
      Shares purchased in each group's participants account in connection with
      this privilege will be subject to a CDSC of 1.00% in the event of
      redemption within one year of purchase, and a commission will be paid to
      authorized dealers who initiate and are responsible for such sales to each
      individual as follows: 1.00% on sales to $2 million, plus 0.80% on the
      next $1 million and 0.50% on the excess over $3 million.
    
 
   
The term "families" includes a person's spouse, children under 21 years of age
and grandchildren, parents, and a person's spouse's parents.
    
 
   
  Purchase orders made pursuant to clause (4) may be placed either through
authorized brokers, dealers or financial intermediaries as described above or
directly with ACCESS, the investment adviser, trust company or bank trust
department,
    
 
                                       31

provided that ACCESS receives federal funds for the purchase by the close of
business on the next business day following acceptance of the order. An
authorized broker, dealer or financial intermediary may charge a transaction fee
for placing an order to purchase shares pursuant to this provision or for
placing a redemption order with respect to such shares. The Fund may terminate,
or amend the terms of, offering shares of the Fund at net asset value to such
groups at any time.
    
 
DEFERRED SALES CHARGE ALTERNATIVES
 
   
  Investors choosing the deferred sales charge alternative may purchase Class A
Shares in an amount of $1 million or more, Class B Shares or Class C Shares. The
public offering price of a CDSC Share is equal to the net asset value per share
without the imposition of a sales charge at the time of purchase. CDSC Shares
are sold without an initial sales charge so that the Fund may invest the full
amount of the investor's purchase payment. The Distributor will compensate
brokers, dealers and financial intermediaries participating in the continuous
public offering of the CDSC Shares out of its own assets, and not out of assets
of the Fund, as a percentage rate of the dollar value of the CDSC Shares
purchased from the Fund by such brokers, dealers and other financial
intermediaries which percentage rate will be equal to (i) with respect to Class
A Shares, 1.00% on sales to $2 million, plus 0.80% on the next $1 million and
0.50% on the excess over $3 million; (ii) 4.00% with respect to Class B Shares;
and (iii) 1.00% with respect to Class C Shares. Such compensation will not
change the price an investor will pay for CDSC Shares or the amount that the
Fund will receive from such sale.
    
 
   
  CDSC Shares redeemed within a specified period of time generally will be
subject to a CDSC at the rates set forth below charged as a percentage of the
dollar amount subject thereto. The amount of the CDSC will vary depending on (i)
the class of CDSC Shares to which such shares belong and (ii) the number of
years from the time of payment for the purchase of the CDSC Shares until the
time of their redemption. The charge will be assessed on an amount equal to the
lesser of the then current market value or the original purchase price of the
CDSC Shares being redeemed. Accordingly, no sales charge will be imposed on
increases in net asset value above the initial purchase price. In addition, no
CDSC will be assessed on CDSC Shares derived from reinvestment of dividends or
capital gains distributions. Solely for purposes of determining the number of
years from the time of any payment for the purchases of CDSC Shares, all
payments during a month will be aggregated and deemed to have been made on the
last day of the month.
    
 
   
  Proceeds from the CDSC and the distribution fee applicable to a class of CDSC
Shares are paid to the Distributor and are used by the Distributor to defray its
expenses related to providing distribution related services to the Fund in
connection with the sale of shares of such class of CDSC Shares, such as the
payment of compensation to selected dealers and agents and for selling such
shares. The combination of the CDSC and the distribution fee facilitates the
ability of the Fund
    
 
                                       32
<PAGE>   390
 
to sell such CDSC Shares without a sales charge being deducted at the time of
purchase.
 
   
  In determining whether a CDSC is applicable to a redemption of CDSC Shares, it
will be assumed that the redemption is made first of any CDSC Shares acquired
pursuant to reinvestment of dividends or distributions, second of CDSC Shares
that have been held for a sufficient period of time such that the CDSC no longer
is applicable to such shares, third of Class A Shares in the shareholder's Fund
account that have converted from Class B Shares or Class C Shares, if any, and
fourth of CDSC Shares held longest during the period of time that a CDSC is
applicable to such CDSC Shares. The charge will not be applied to dollar amounts
representing an increase in the net asset value since the time of purchase.
    
 
  To provide an example, assume an investor purchased 100 Class B Shares at $10
per share (at a cost of $1,000) and in the second year after purchase, the net
asset value per share is $12 and, during such time, the investor has acquired 10
additional Class B Shares upon dividend reinvestment. If at such time the
investor makes his first redemption of 50 shares (proceeds of $600), 10 shares
will not be subject to charge because of dividend reinvestment. With respect to
the remaining 40 shares, the charge is applied only to the original cost of $10
per share and not to the increase in net asset value of $2 per share. Therefore,
$400 of the $600 redemption proceeds will be charged at a rate of 3.75% (the
applicable rate in the second year after purchase).
 
   
  CLASS A SHARE PURCHASES OF $1 MILLION OR MORE. No sales charge is payable at
the time of purchase on investments in Class A Shares of $1 million or more,
although for such investments the Fund imposes a CDSC of 1.00% on redemptions
made within one year of the purchase. A commission will be paid to dealers who
initiate and are responsible for purchases of $1 million or more as follows:
1.00% on sales to $2 million, plus 0.80% on the next $1 million and 0.50% on the
excess over $3 million.
    
 
   
  CLASS B SHARES. Class B Shares redeemed within seven years of purchase
generally will be subject to a CDSC at the rates set forth below, charged as a
percentage of the dollar amount subject thereto:

  The CDSC generally is waived on redemptions of Class B Shares made pursuant to
the Systematic Withdrawal Plan. See "Shareholder Services--Systematic Withdrawal
Plan."
    
 
   
  CLASS C SHARES. Class C Shares redeemed within the first 12 months of purchase
generally will be subject to a CDSC of 1.00% of the dollar amount subject
thereto. Class C Shares redeemed thereafter will not be subject to a CDSC.
    
 
   
  Conversion Feature. Class B Shares purchased on or after June 1, 1996 and any
dividend reinvestment plan shares received thereon, automatically convert to
Class A Shares eight years after the end of the calendar month in which the
shares were purchased. Class B Shares purchased before June 1, 1996, and any
dividend reinvestment plan shares received thereon, automatically convert to
Class A Shares seven years after the end of the calendar month in which the
shares were purchased. Class C Shares purchased before January 1, 1997, and any
dividend reinvestment plan shares received thereon, automatically convert to
Class A Shares ten years after the end of the calendar month in which such
shares were purchased. Such conversion will be on the basis of the relative net
asset values per share, without the imposition of any sales load, fee or other
charge.
    
 
   
  The conversion of such shares to Class A Shares is subject to the continuing
availability of an opinion of counsel to the effect that (i) the assessment of
the higher distribution and service fee and ACCESS costs with respect to such
shares does not result in the Fund's dividends or distributions constituting
"preferential dividends" under the Internal Revenue Code of 1986, as amended
(the "Code"), and (ii) that the conversion of such shares does not constitute a
taxable event under federal income tax law. The conversion may be suspended if
such an opinion is no longer available and such shares might continue to be
subject to the higher aggregate fees applicable to such class of shares for an
indefinite period.
    
 
   
  WAIVER OF CONTINGENT DEFERRED SALES CHARGE. The CDSC is waived on redemptions
of Class B Shares and Class C Shares (i) following the death or disability (as
defined in the Code) of a shareholder, (ii) in connection with required minimum
distributions from an IRA or other retirement plan, (iii) pursuant to the Fund's
systematic withdrawal plan but limited to 12% annually of the initial value of
the account and (iv) effected pursuant to the right of the Fund to liquidate a
shareholder's account as described herein under "Redemption of Shares." The CDSC
also is waived on redemptions of Class C Shares as it relates to the
reinvestment of redemption proceeds in shares of the same class of the Fund
within 120 days after redemption. See "Shareholder Services" and "Redemption of
Shares" for further discussion of the waiver provisions.
    
 
NET ASSET VALUE
 
  The net asset value per share of the Fund will be determined separately for
each class of shares. The net asset value per share of a given class of shares
of the Fund is determined by calculating the total value of the Fund's assets
attributable to such
 
                                       34
<PAGE>   392
 
class of shares, deducting its total liabilities attributable to such class of
shares, and dividing the result by the number of shares of such class
outstanding. The net asset value for the Fund is computed once daily as of 5:00
p.m. Eastern time Monday through Friday, except on customary business holidays,
or except on any day on which no purchase or redemption orders are received, or
there is not a sufficient degree of trading in the Fund's portfolio securities
such that the Fund's net asset value per share might be materially affected. The
Fund reserves the right to calculate the net asset value and to adjust the
public offering price based thereon more frequently than once a day if deemed
desirable. The net asset value per share of the different class of shares are
expected to be substantially the same; from time to time, however, the per share
net asset value of the different class of shares may differ.
 
  Portfolio securities are valued by using market quotations, prices provided by
market makers or estimates of market values obtained from yield data relating to
instruments or securities with similar characteristics in accordance with
procedures established in good faith by the Board of Trustees of the Trust, of
which the Fund is a series. Securities with remaining maturities of 60 days or
less are valued at amortized cost when amortized cost is determined in good
faith by or under the direction of the Board of Trustees of the Trust to be
representative of the fair value at which it is expected such securities may be
resold. Any securities or other assets for which current market quotations are
not readily available are valued at their fair value as determined in good faith
under procedures established by and under the general supervision of the Board
of Trustees of the Trust.
 
- ------------------------------------------------------------------------------
SHAREHOLDER SERVICES
- ------------------------------------------------------------------------------
 
  The Fund offers a number of shareholder services designed to facilitate
investment in its shares at little or no extra cost to the investor. Below is a
description of such services. Unless otherwise described below, each of these
services may be modified or terminated by the Fund at any time.
 
   
  INVESTMENT ACCOUNT. ACCESS, transfer agent for the Fund and a wholly-owned
subsidiary of Van Kampen American Capital, performs bookkeeping, data processing
and administration services related to the maintenance of shareholder accounts.
Each shareholder has an investment account under which shares are held by
ACCESS. Except as described in this Prospectus, after each share transaction in
an account, the shareholder receives a statement showing the activity in the
account. Each shareholder will receive statements at least quarterly from ACCESS
showing any reinvestments of dividends and capital gains distributions and any
other activity in the account since the preceding statement. Such shareholders
also will receive separate confirmations for each purchase or sale transaction
other than reinvestment of dividends and capital gains distributions and
systematic purchases or redemptions. Additions to an investment account may be
made at any time by
    
 
                                       35
<PAGE>   393
 
purchasing shares through authorized brokers, dealers or financial
intermediaries or by mailing a check directly to ACCESS.
 
  SHARE CERTIFICATES. Generally, the Fund will not issue share certificates.
However, upon written or telephone request to the Fund, a share certificate will
be issued, representing shares (with the exception of fractional shares) of the
Fund. A shareholder will be required to surrender such certificates upon
redemption thereof. In addition, if such certificates are lost the shareholder
must write to Van Kampen American Capital Funds, c/o ACCESS, P.O. Box 418256,
Kansas City, MO 64141-9256, requesting an "affidavit of loss" and to obtain a
Surety Bond in a form acceptable to ACCESS. On the date the letter is received
ACCESS will calculate a fee for replacing the lost certificate equal to no more
than 2.00% of the net asset value of the issued shares and bill the party to
whom the replacement certificate was mailed.
 
   
  REINVESTMENT PLAN. A convenient way for investors to accumulate additional
shares is by accepting dividends and capital gains distributions in shares of
the Fund. Such shares are acquired at net asset value (without sales charge) on
the record date of such dividend or distribution. Unless the shareholder
instructs otherwise, the reinvestment plan is automatic. This instruction may be
made by telephone by calling (800) 421-5666 ((800) 421-2833 for the hearing
impaired) or in writing to ACCESS. The investor may, on the initial application
or prior to any declaration, instruct that dividends be paid in cash and capital
gains distributions be reinvested at net asset value, or that both dividends and
capital gains distributions be paid in cash. For further information, see
"Distributions from the Fund."
    
 
  AUTOMATIC INVESTMENT PLAN. An automatic investment plan is available under
which a shareholder can authorize ACCESS to charge a bank account on a regular
basis to invest pre-determined amounts in the Fund. Additional information is
available from the Distributor or authorized brokers, dealers or financial
intermediaries.
 
   
  DIVIDEND DIVERSIFICATION. A shareholder may, upon written request or by
completing the appropriate section of the application form accompanied by this
Prospectus or by calling (800) 421-5666 ((800) 421-2833 for the hearing
impaired), elect to have all dividends and other distributions paid on a class
of shares of the Fund invested into shares of the same class of any other
Participating Fund, Tax Free Money Fund or Reserve Fund so long as a
pre-existing account for such class of shares exists for such shareholder.
    
 
  If the qualified pre-existing account does not exist, the shareholder must
establish a new account subject to minimum investment and other requirements of
the fund into which distributions would be invested. Distributions are invested
into the selected fund at its net asset value as of the payable date of the
distribution only if shares of such selected fund have been registered for sale
in the investor's state.
 
   
  EXCHANGE PRIVILEGE. Shares of the Fund may be exchanged with shares of another
Participating Fund, subject to certain limitations. Before effecting an
    
 
                                       36
<PAGE>   394
 
exchange, shareholders in the Fund should obtain and read a current prospectus
of the fund into which the exchange is to be made. SHAREHOLDERS MAY ONLY
EXCHANGE INTO SUCH OTHER FUNDS AS ARE LEGALLY AVAILABLE FOR SALE IN THEIR STATE.
 
  To be eligible for exchange, shares of the Fund must have been registered in
the shareholder's name for at least 30 days prior to an exchange. Shares of the
Fund registered in a shareholder's name for less than 30 days may only be
exchanged upon receipt of prior approval of the Adviser. Under normal
circumstances, it is the policy of the Adviser not to approve such requests.
 
  Class A Shares of Van Kampen American Capital funds that generally impose an
initial sales charge are not subject to any sales charge upon exchange into the
Fund. Class A Shares of Van Kampen American Capital funds that generally do not
impose an initial sales charge are subject to the appropriate sales charge
applicable to Class A Shares of the Fund.
 
   
  No sales charge is imposed upon the exchange of Class B Shares or Class C
Shares. The CDSC schedule and conversion schedule applicable to a Class B Share
or Class C Share acquired through the exchange privilege is determined by
reference to the Van Kampen American Capital fund from which such share
originally was purchased. The holding period of a Class B Share or Class C Share
acquired through the exchange privilege is determined by reference to the date
such share originally was purchased from a Van Kampen American Capital fund.
    
 
  Exchanges of shares are sales and may result in a gain or loss for federal
income tax purposes. If the shares exchanged have been held for less than 91
days, the sales charge paid on such shares is not included in the tax basis of
the exchanged shares, but is carried over and included in the tax basis of the
shares acquired.
 
   
  A shareholder wishing to make an exchange may do so by sending a written
request to ACCESS or by contacting the telephone transaction line at (800)
421-5684 ((800) 421-2833 for the hearing impaired). A shareholder automatically
has telephone exchange privileges unless otherwise designated in the application
form accompanied by this Prospectus. The exchange will take place at the
relative net asset values of the shares next determined after receipt of such
request with adjustment for any additional sales charge. Any shares exchanged
begin earning dividends on the next business day after the exchange is affected.
Van Kampen American Capital and its subsidiaries, including ACCESS
(collectively, "VKAC"), and the Fund employ procedures considered by them to be
reasonable to confirm that instructions communicated by telephone are genuine.
Such procedures include requiring certain personal identification information
prior to acting upon telephone instructions, tape recording telephone
communications, and providing written confirmation of instructions communicated
by telephone. If reasonable procedures are employed, a shareholder agrees that
neither VKAC nor the Fund will be liable for following telephone instructions
which it reasonably believes to be genuine. VKAC and the Fund may be liable for
any losses due to unauthorized or fraudulent instructions if reasonable
procedures are not followed. Exchanges are effected at the net asset value per
share next calculated after the
    
 
                                       37
<PAGE>   395
 
   
request is received in good order with adjustment for any additional sales
charges. If the exchanging shareholder does not have an account in the fund
whose shares are being acquired, a new account will be established with the same
registration, dividend and capital gains options (except dividend
diversification options) and broker, dealer or financial intermediary of record
as the account from which shares are exchanged, unless otherwise specified by
the shareholder. In order to establish a systematic withdrawal plan for the new
account or reinvest dividends from the new account into another fund an
exchanging shareholder must file a specific written request. The Fund reserves
the right to reject any order to acquire shares through exchange. In addition,
the Fund may modify, restrict or terminate the exchange privilege at any time on
60 days' notice to its shareholders of any termination or material amendment.
    
 
   
  A prospectus of any of these mutual funds may be obtained from any broker,
dealer or financial intermediary or the Distributor. An investor considering an
exchange to one of such funds should refer to the prospectus for additional
information regarding such fund prior to investing.
    
 
   
  SYSTEMATIC WITHDRAWAL PLAN. Any investor whose shares in a single account
total $10,000 or more at the offering price next computed after receipt of
instructions may establish a monthly, quarterly, semi-annual or annual
withdrawal plan. Any investor whose shares in a single account total $5,000 or
more at the offering price next computed after receipt of instructions may
establish a quarterly, semi-annual or annual withdrawal plan. This plan provides
for the orderly use of the entire account, not only the income but also the
capital, if necessary. Each withdrawal constitutes a redemption of shares on
which taxable gain or loss will be recognized. The plan holder may arrange for
monthly, quarterly, semi-annual, or annual checks in any amount not less than
$25.
    
 
   
  Holders of Class B Shares and Class C Shares who establish a withdrawal plan
may redeem up to 12% annually of the shareholder's initial account balance
without incurring a contingent deferred sales charge. Initial account balance
means the amount of the shareholder's investment at the time the election to
participate in the plan is made.
    
 
  Under the plan, sufficient shares of the Fund are redeemed to provide the
amount of the periodic withdrawal payment. Dividends and capital gains
distributions on shares held under the plan are reinvested in additional shares
at the next determined net asset value. If periodic withdrawals continuously
exceed reinvested dividends and capital gains distributions, the shareholder's
original investment will be correspondingly reduced and ultimately exhausted.
Withdrawals made concurrently with purchases of additional shares ordinarily
will be disadvantageous to the shareholder because of the duplication of sales
charges. The Fund reserves the right to amend or terminate the systematic
withdrawal program on thirty days' notice to its shareholders.
 
                                       38
<PAGE>   396
 
  CHECK WRITING PRIVILEGE. Holders of Class A Shares of the Fund for which
certificates have not been issued and which are in a non-escrow status may
appoint ACCESS as agent by completing the Authorization for Redemption by Check
Form and the appropriate section of the application and returning the form and
the application to ACCESS. Once the form is properly completed, signed and
returned to the agent, a supply of checks drawn on State Street Bank and Trust
Company ("State Street Bank") will be sent to such shareholder. These checks may
be made payable by the holder of Class A Shares to the order of any person in
any amount of $100 or more.
 
  When a check is presented to State Street Bank for payment, full and
fractional Class A Shares required to cover the amount of the check are redeemed
from the shareholder's account by ACCESS at the next determined net asset value.
Check writing redemptions represent the sale of Class A Shares. Any gain or loss
realized on the sale of Class A Shares is a taxable event. See "Redemption of
Shares."
 
   
  Checks will not be honored for redemption of Class A Shares held less than 15
calendar days, unless such Class A Shares have been paid for by bank wire. Any
Class A Shares for which there are outstanding certificates may not be redeemed
by check. If the amount of the check is greater than the proceeds of all
uncertificated shares held in the shareholder's Class A Share account, the check
will be returned and the shareholder may be subject to additional charges.
Holders of Class A Shares may not liquidate the entire account by means of a
check. The check writing privilege may be terminated or suspended at any time by
the Fund or State Street Bank. Retirement plans and accounts that are subject to
backup withholding are not eligible for the privilege. A "stop payment" system
is not available on these checks. See the Statement of Additional Information
for further information regarding the establishment of the privilege.
    
 
  AUTOMATED CLEARING HOUSE ("ACH") DEPOSITS. Holders of Class A Shares can use
ACH to have redemption proceeds deposited electronically into their bank
accounts. Redemptions transferred to a bank account via the ACH plan are
available to be credited to the account on the second business day following
normal payment. In order to utilize this option, the shareholder's bank must be
a member of Automated Clearing House. In addition, the shareholder must fill out
the appropriate section of the account application. The shareholder must also
include a voided check or deposit slip from the bank account into which
redemptions are to be deposited together with the completed application. Once
ACCESS has received the application and the voided check or deposit slip, such
shareholder's designated bank account, following any redemption, will be
credited with the proceeds of such redemption. Once enrolled in the ACH plan, a
shareholder may terminate participation at any time by writing ACCESS.

- ------------------------------------------------------------------------------
REDEMPTION OF SHARES
- ------------------------------------------------------------------------------
 
  Shareholders may redeem for cash some or all of their shares without charge by
the Fund (other than, with respect to CDSC Shares, the applicable contingent
deferred sales charge) at any time by sending a written request in proper form
directly to ACCESS, P. O. Box 418256, Kansas City, Missouri 64141-9256, by
placing the redemption request through an authorized dealer or by calling the
Fund.
 
  WRITTEN REDEMPTION REQUESTS. In the case of redemption requests sent directly
to ACCESS, the redemption request should indicate the number of shares to be
redeemed, the class designation of such shares, the account number and be signed
exactly as the shares are registered. Signatures must conform exactly to the
account registration. If the proceeds of the redemption would exceed $50,000, or
if the proceeds are not to be paid to the record owner at the record address, or
if the record address has changed within the previous 30 days, signature(s) must
be guaranteed by one of the following: a bank or trust company; a broker-dealer;
a credit union; a national securities exchange, registered securities
association or clearing agency; a savings and loan association; or a federal
savings bank. If certificates are held for the shares being redeemed, such
certificates must be endorsed for transfer or accompanied by an endorsed stock
power and sent with the redemption request. In the event the redemption is
requested by a corporation, partnership, trust, fiduciary, executor or
administrator, and the name and title of the individual(s) authorizing such
redemption is not shown in the account registration, a copy of the corporate
resolution or other legal documentation appointing the authorized signer and
certified within the prior 60 days must accompany the redemption request. The
redemption price is the net asset value per share next determined after the
request is received by ACCESS in proper form. Payment for shares redeemed (less
any sales charge, if applicable) will ordinarily be made by check mailed within
three business days after acceptance by ACCESS of the request and any other
necessary documents in proper order. Such payments may be postponed or the right
of redemption suspended as provided by the rules of the SEC. If the shares to be
redeemed have been recently purchased by check, ACCESS may delay mailing a
redemption check until it confirms that the purchase check has cleared, usually
a period of up to 15 days. Any gain or loss realized on the redemption of shares
is a taxable event.
 
  DEALER REDEMPTION REQUESTS. Shareholders may sell shares through their
securities dealer, who will telephone the request to the Distributor. Orders
received from dealers must be at least $500 unless transmitted via the FUNDSERV
network. The redemption price for such shares is the net asset value next
calculated after an order is received by a dealer provided such order is
transmitted to the Distributor prior to the Distributor's close of business on
such day. It is the responsibility of dealers to transmit redemption requests
received by them to the Distributor so they will be received prior to such time.
Any change in the redemption price due to failure of the Distributor to receive
a sell order prior to such time must be settled between the
 
                                       40
<PAGE>   398
 
shareholder and dealer. Shareholders must submit a written redemption request in
proper form (as described above under "Written Redemption Requests") to the
dealer within three business days after calling the dealer with the sell order.
Payment for shares redeemed (less any sales charge, if applicable) will
ordinarily be made by check mailed within three business days to the dealer.
 
   
  TELEPHONE REDEMPTION REQUESTS. The Fund permits redemption of shares by
telephone and for redemption proceeds to be sent to the address of record for
the account or to the bank account of record as described below. To establish
such privilege, a shareholder must complete the appropriate section of the
application accompanying this Prospectus or call the Fund at (800) 421-5666
((800) 421-2833 for the hearing impaired) to request that a copy of the
Telephone Redemption Authorization form be sent to them for completion. To
redeem shares, contact the telephone transaction line at (800) 421-5684. VKAC
and the Fund employ procedures considered by them to be reasonable to confirm
that instructions communicated by telephone are genuine. Such procedures include
requiring certain personal identification information prior to acting upon
telephone instructions, tape recording telephone communications, and providing
written confirmation of instructions communicated by telephone. If reasonable
procedures are employed, a shareholder agrees that neither VKAC nor the Fund
will be liable for following instructions which it reasonably believes to be
genuine. VKAC and the Fund may be liable for any losses due to unauthorized or
fraudulent instructions if reasonable procedures are not followed. Telephone
redemptions may not be available if the shareholder cannot reach ACCESS by
telephone, whether because all telephone lines are busy or for any other reason;
in such case, a shareholder would have to use the Fund's other redemption
procedures previously described. Requests received by ACCESS prior to 4:00 p.m.,
New York time, on a regular business day will be processed at the net asset
value per share determined that day. These privileges are available for all
accounts other than retirement accounts. The telephone redemption privilege is
not available for shares represented by certificates. If the shares to be
redeemed have been recently purchased by check, ACCESS may delay mailing a
redemption check or wiring redemption proceeds until it confirms that the
purchase check has cleared, usually a period of up to 15 days. If an account has
multiple owners, ACCESS may rely on the instructions of any one owner.
    
 
  For redemptions authorized by telephone, amounts of $50,000 or less may be
redeemed daily if the proceeds are to be paid by check sent to the shareholders'
address of record and amounts of at least $1,000 and up to $1 million may be
redeemed daily if the proceeds are to be paid by wire sent to the shareholder's
bank account of record. The proceeds must be payable to the shareholder(s) of
record. Proceeds from redemptions to be paid by check will ordinarily be mailed
within three business days to the shareholder's address of record. Proceeds from
redemptions to be paid by wire will ordinarily be wired on the next business day
to the shareholder's bank account of record. This privilege is not available if
the address of record has been changed within 30 days prior to a telephone
redemption request.

The Fund reserves the right at any time to terminate, limit or otherwise modify
this telephone redemption privilege.
 
   
  REDEMPTION UPON DISABILITY. The Fund will waive the CDSC on redemptions
following the disability of holders of Class B Shares and Class C Shares. An
individual will be considered disabled for this purpose if he or she meets the
definition thereof in Section 72(m)(7) of the Code, which in pertinent part
defines a person as disabled if such person "is unable to engage in any
substantial gainful activity by reason of any medically determinable physical or
mental impairment which can be expected to result in death or to be of
long-continued and indefinite duration." While the Fund does not specifically
adopt the balance of the Code's definition which pertains to furnishing the
Secretary of Treasury with such proof as he or she may require, the Distributor
will require satisfactory proof of disability before it determines to waive the
CDSC on Class B Shares and Class C Shares.
    
 
   
  In cases of disability, the CDSCs on Class B Shares and Class C Shares will be
waived where the disabled person is either an individual shareholder or owns the
shares as a joint tenant with right of survivorship or is the beneficial owner
of a custodial or fiduciary account, and where the redemption is made within one
year of the initial determination of disability. This waiver of the CDSC on
Class B Shares and Class C Shares applies to a total or partial redemption, but
only to redemptions of shares held at the time of the initial determination of
disability.
    
 
   
  GENERAL REDEMPTION INFORMATION. The Fund may redeem any shareholder account
with a net asset value on the date of the notice of redemption less than the
minimum investment as specified by the Trustees. At least 60 days advance
written notice of any such involuntary redemption is required and the
shareholder is given an opportunity to purchase the required value of additional
shares at the next determined net asset value without sales charge. Any
applicable CDSC will be deducted from the proceeds of this redemption. Any
involuntary redemption may only occur if the shareholder account is less than
the minimum investment due to shareholder redemptions.
    
 
   
  REINSTATEMENT PRIVILEGE. Holders of Class A Shares or Class B Shares who have
redeemed shares of the Fund may reinstate any portion or all of the net proceeds
of such redemption in Class A Shares of the Fund. Holders of Class C Shares who
have redeemed shares of the Fund may reinstate any portion or all of the net
proceeds of such redemption in Class C Shares of the Fund with credit given for
any CDSC paid upon such redemption. Such reinstatement is made at the net asset
value (without sales charge except as described under "Shareholder Services --
Exchange Privilege") next determined after the order is received, which must be
within 180 days after the date of the redemption. See "Purchase of
Shares -- Waiver of Contingent Deferred Sales Charge." Reinstatement at net
asset value is also offered to participants in those eligible retirement plans
held or administered by Van Kampen American Capital Trust Company for repayment
of principal (and interest) on their borrowings on such plans.

DISTRIBUTION AND SERVICE PLANS
    
- ------------------------------------------------------------------------------
 
  The Fund has adopted a distribution plan (the "Distribution Plan") with
respect to each class of its shares pursuant to Rule 12b-1 under the 1940 Act.
The Fund also has adopted a service plan (the "Service Plan") with respect to
each class of its shares. The Distribution Plan and the Service Plan provide
that the Fund may spend a portion of the Fund's average daily net assets
attributable to each class of shares in connection with distribution of the
respective class of shares and in connection with the provision of ongoing
services to shareholders of each class. The Distribution Plan and the Service
Plan are being implemented through an agreement with the Distributor and
sub-agreements between the Distributor and brokers, dealers and financial
intermediaries (collectively, "Selling Agreements") that may provide for their
customers or clients certain services or assistance.
 
   
  CLASS A SHARES. The Fund may spend an aggregate amount up to 0.25% per year of
the average daily net assets attributable to the Class A Shares of the Fund
pursuant to the Distribution Plan and Service Plan. From such amount, the Fund
may spend up to 0.25% per year of the Fund's average daily net assets
attributable to the Class A Shares pursuant to the Service Plan in connection
with the ongoing provision of services to holders of such shares by the
Distributor and by brokers, dealers or financial intermediaries and in
connection with the maintenance of such shareholders' accounts. The Fund pays
the Distributor the lesser of the balance of the 0.25% not paid to such brokers,
dealers or financial intermediaries or the amount of the Distributor's actual
distribution-related expense.
    
 
  CLASS B SHARES. The Fund may spend up to 0.75% per year of the average daily
net assets attributable to the Class B Shares of the Fund pursuant to the
Distribution Plan. In addition, the Fund may spend up to 0.25% per year of the
Fund's average daily net assets attributable to the Class B Shares pursuant to
the Service Plan in connection with the ongoing provision of services to holders
of such shares by the Distributor and by brokers, dealers or financial
intermediaries and in connection with the maintenance of such shareholders'
accounts.
 
   
  CLASS C SHARES. The Fund may spend up to 0.75% per year of the average daily
net assets attributable to the Class C Shares of the Fund pursuant to the
Distribution Plan. From such amount, the Fund, or the Distributor as agent for
the Fund, pays brokers, dealers or financial intermediaries in connection with
the distribution of the Class C Shares up to 0.75% of the Fund's average daily
net assets attributable to Class C Shares maintained in the Fund more than one
year by such broker's, dealer's or financial intermediary's customers. The Fund
pays the Distributor the lesser of the balance of 0.75% not paid to such
brokers, dealers or financial intermediaries or the amount of the Distributor's
actual distribution-related expense attributable to the Class C Shares. In
addition, the Fund may spend up to 0.25% per year of the Fund's average daily
net assets attributable to the Class C Shares pursuant to the Service Plan in
connection with the ongoing provision of services to holders of such shares by
the Distributor and by brokers, dealers or financial
    
 
                                       43
<PAGE>   401
 
intermediaries and in connection with the maintenance of such shareholders'
accounts.
 
  OTHER INFORMATION. Amounts payable to the Distributor with respect to the
Class A Shares under the Distribution Plan in a given year may not fully
reimburse the Distributor for its actual distribution-related expenses during
such year. In such event, with respect to the Class A Shares, there is no
carryover of such reimbursement obligations to succeeding years.
 
   
  The Distributor's actual expenses with respect to a class of CDSC Shares (for
purposes of this section, excluding any Class A Shares that may be subject to a
CDSC) for any given year may exceed the amounts payable to the Distributor with
respect to such class of CDSC Shares under the Distribution Plan, the Service
Plan and payments received pursuant to the CDSC. In such event, with respect to
any such class of CDSC Shares, any unreimbursed expenses will be carried forward
and paid by the Fund (up to the amount of the actual expenses incurred) in
future years so long as such Distribution Plan is in effect. Except as mandated
by applicable law, the Fund does not impose any limit with respect to the number
of years into the future that such unreimbursed expenses may be carried forward
(on a Fund level basis). Because such expenses are accounted on a Fund level
basis, in periods of extreme net asset value fluctuation such amounts with
respect to a particular CDSC Share may be greater or less than the amount of the
initial commission (including carrying cost) paid by the Distributor with
respect to such CDSC Share. In such circumstances, a shareholder of such CDSC
Share may be deemed to incur expenses attributable to other shareholders of such
class. As of December 31, 1996, there were $448,111 and $4,777 of unreimbursed
distribution related expenses with respect to Class B Shares and Class C Shares,
respectively, representing 4.42% and 1.35% of the Fund's net assets attributable
to Class B Shares and Class C Shares, respectively. If the Distribution Plan was
terminated or not continued, the Fund would not be contractually obligated to
pay the Distributor for any expenses not previously reimbursed by the Fund or
recovered through CDSCs.
    
 
   
  Because the Fund is a series of the Trust, amounts paid to the Distributor as
reimbursement for expenses of one series of the Trust may indirectly benefit the
other funds which are series of the Trust. The Distributor will endeavor to
allocate such expenses among such funds in an equitable manner. The Distributor
will not use the proceeds from the CDSC applicable to a particular class of
shares to defray distribution-related expenses attributable to any other class
of shares. Various federal and state laws prohibit national banks and some
state-chartered commercial banks from underwriting or dealing in the Fund's
shares. In addition, state securities laws on this issue may differ from the
interpretations of federal law, and banks and financial institutions may be
required to register as dealers pursuant to state law. In the unlikely event
that a court were to find that these laws prevent such banks from providing such
services described above, the Fund would seek alternate providers and expects
that shareholders would not experience any disadvantage.

- ------------------------------------------------------------------------------
DISTRIBUTIONS FROM THE FUND
- ------------------------------------------------------------------------------
 
  The Fund's present policy, which may be changed at any time by the Board of
Trustees, is to declare daily and pay monthly distributions of all or
substantially all net investment income of the Fund. Net investment income
consists of all interest income, dividends, and other ordinary income earned by
the Fund, less all expenses of the Fund attributable to the class of shares in
question. Net short-term capital gains, if any, may be distributed throughout
the year. Expenses of the Fund are accrued each day. Net realized long-term
capital gains, if any, are expected to be distributed, to the extent permitted
by applicable law, to shareholders at least annually. Distributions cannot be
assured, and the amount of each monthly distribution may vary.
 
  Distributions with respect to each class of shares will be calculated in the
same manner on the same day and will be in the same amount, except that the
different distribution and service fees and any incremental administrative
expenses relating to each class of shares will be borne exclusively by the
respective class and may cause the distributions relating to the different
classes of shares to differ. Generally, distributions with respect to a class of
shares subject to a higher distribution fee will be lower than distributions
with respect to a class of shares subject to a lower distribution fee.
 
   
  Investors will be entitled to begin receiving dividends on their shares on the
business day after ACCESS receives payments for such shares. However, shares
become entitled to dividends on the day ACCESS receives payment for the shares
either through a fed wire or NSCC settlement. Shares remain entitled to
dividends through the day such shares are processed for payment on redemption.
    
 
  Distribution checks may be sent to parties other than the shareholder in whose
name the account is registered. Persons wishing to utilize this service should
complete the appropriate section of the account application accompanying this
Prospectus or available from Van Kampen American Capital Funds, c/o ACCESS P.O.
Box 418256, Kansas City, MO 64141-9256. After ACCESS receives this completed
form, distribution checks will be sent to the bank or other person so designated
by such shareholder.
 
   
  PURCHASE OF ADDITIONAL SHARES WITH DISTRIBUTIONS.  The Fund will automatically
credit monthly distributions and any annual net long-term capital gain
distributions to a shareholder's account in additional shares of the Fund valued
at net asset value, without a sales charge. Unless a shareholder instructs
otherwise, the Reinvestment Plan is automatic. Instruction may be made by
telephone by calling (800) 421-5666 ((800) 421-2833 for the hearing impaired) or
in writing to ACCESS. See "Shareholder Services -- Reinvestment Plan."

- ------------------------------------------------------------------------------
TAX STATUS
- ------------------------------------------------------------------------------
 
   
  NEW YORK TAXATION.  Individual shareholders will not be subject to New York
State or New York City income tax on distributions attributable to interest on
New York municipal securities. Individual shareholders will be subject to New
York State or New York City income tax on distributions attributable to other
income of the Fund (including net capital gain), and on gain on the sale of
shares of the Fund. Corporations should note that all or a part of any
distribution from the Fund, and gain on the sale of shares of the Fund, may be
subject to the New York State corporate franchise tax and the New York City
general corporation tax.
    
 
  Under currently applicable New York State law, the highest marginal New York
State income tax rate imposed on individuals for taxable years beginning in 1994
is 7.875%, which is currently scheduled to decline to approximately 7.59% for
taxable years beginning in 1995 and to 7.125% for taxable years beginning
thereafter. The highest marginal New York City income tax rate currently imposed
on individuals is 4.57%. In addition, individual taxpayers with New York
adjusted gross income in excess of $100,000 must pay a supplemental tax to
recognize the benefit of graduated tax rates. Due to the ongoing budgetary
problems of both New York State and New York City, these income tax rates are
subject to change at any time. Shareholders subject to taxation in a state other
than New York will realize a lower after-tax rate of return if distributions
from the Fund are not exempt from taxation in such other state.
 
   
  FEDERAL INCOME TAXATION.  The Fund has qualified and intends to continue to
qualify each year and to elect to be treated as a regulated investment company
under Subchapter M of the Code. To qualify as a regulated investment company,
the Fund must comply with certain requirements of the Code relating to, among
other things, the source of its income and diversification of its assets.
    
 
   
  If the Fund so qualifies and distributes each year to its shareholders at
least 90% of its net investment income (including tax-exempt interest, taxable
income and net short-term capital gain, but not net capital gains, which are the
excess of net long-term capital gains over net short-term capital losses), it
will not be required to pay federal income taxes on any income distributed to
shareholders. The Fund intends to distribute at least the minimum amount of net
investment income necessary to satisfy the 90% distribution requirement. The
Fund will not be subject to federal income tax on any net capital gains
distributed to shareholders.
    
 
   
  In order to avoid a 4% excise tax, the Fund will be required to distribute, by
December 31 of each year, at least 98% of its ordinary income (not including
tax-exempt income) for such year and at least 98% of its capital gain net income
(the latter of which generally is computed on the basis of the one-year period
ending on October 31 of such year), plus any amounts that were not distributed
in previous taxable years. For purposes of the excise tax, any ordinary income
or capital gain
    
 
                                       46
<PAGE>   404
 
   
net income retained by, and subject to federal income tax in the hands of, the
Fund will be treated as having been distributed.
    
 
   
  If the Fund failed to qualify as a regulated investment company or failed to
satisfy the 90% distribution requirement in any taxable year, the Fund would be
taxed as an ordinary corporation on its taxable income (even if such income were
distributed to its shareholders) and all distributions out of earnings and
profits would be taxed to shareholders as ordinary income. To qualify again as a
regulated investment company in a subsequent year, the Fund may be required to
pay an interest charge on 50% of its earnings and profits attributable to
non-regulated investment company years and would be required to distribute such
earnings and profits to shareholders (less any interest charge). In addition, if
the Fund failed to qualify as a regulated investment company for its first
taxable year or, if immediately after qualifying as a regulated investment
company for any taxable year, it failed to qualify for a period greater than one
taxable year, the Fund would be required to recognize any net built-in gains
(the excess of aggregate gains, including items of income, over aggregate losses
that would have been realized if it had been liquidated) in order to qualify as
a regulated investment company in a subsequent year.
    
 
   
  Some of the Fund's investment practices are subject to special provisions of
the Code that, among other things, may defer the use of certain losses of the
Fund and affect the holding period of the securities held by the Fund and the
character of the gains or losses realized by the Fund. These provisions may also
require the Fund to mark-to-market some of the positions in its portfolio (i.e.,
treat them as if they were sold for fair market value at the end of the
tax-year), which may cause the Fund to recognize income without receiving cash
with which to make distributions in amounts necessary to satisfy the 90%
distribution requirement and the distribution requirements for avoiding income
and excise taxes. The Fund will monitor its transactions and may make certain
tax elections in order to mitigate the effect of these rules and prevent
disqualification of the Fund as a regulated investment company.
    
 
   
  The Fund's ability to dispose of portfolio securities may be limited by the
requirement for qualification as a regulated investment company that less than
30% of the Fund's annual gross income be derived from the disposition of
securities held for less than three months.
    
 
   
  Investments of the Fund in securities issued at a discount or providing for
deferred interest or payment of interest in kind are subject to special tax
rules that will affect the amount, timing and character of distributions to
shareholders. For example, with respect to securities issued at a discount, the
Fund will be required to accrue as income each year a portion of the discount
and to distribute such income each year in order to maintain its qualification
as a regulated investment company and to avoid income and excise taxes. In order
to generate sufficient cash to make distributions necessary to satisfy the 90%
distribution requirement and to avoid income and excise taxes, the Fund may have
to dispose of securities that it would
    
 
                                       47
<PAGE>   405
 
   
otherwise have continued to hold. A portion of the discount relating to certain
stripped tax-exempt obligations may constitute taxable income when distributed
to shareholders.
    
 
   
  DISTRIBUTIONS.  The Fund intends to invest in sufficient tax-exempt municipal
securities to permit payment of "exempt-interest dividends" (as defined in the
Code). Dividends paid by the Fund from the net tax-exempt interest earned from
municipal securities qualify as exempt-interest dividends if, at the close of
each quarter of its taxable year, at least 50% of the value of the total assets
of the Fund consists of municipal securities.
    
 
   
  The Tax Reform Act of 1986 (the "Tax Reform Act") may have an adverse impact
upon the Fund and its shareholders. The Tax Reform Act imposed new limitations
on the use and investment of the proceeds of state and local government bonds
and other funds, which limitations must be satisfied in order to maintain the
exclusion from gross income for interest on such bonds. The provisions of the
Tax Reform Act generally apply to bonds issued after August 15, 1986. In light
of these requirements, bond counsel qualify their opinions as to the federal tax
status of bonds issued after August 15, 1986 by making them contingent on the
issuer's future compliance with these limitations. Any failure on the part of an
issuer to comply could cause the interest on its bonds to become taxable to
investors retroactive to the date the bonds were issued.
    
 
   
  Except as provided below, exempt-interest dividends paid to shareholders
generally are not includable in the shareholders' gross income for federal
income tax purposes. The percentage of the total dividends paid by the Fund
during any taxable year that qualify as exempt-interest dividends will be the
same for all shareholders of the Fund receiving dividends during such year.
    
 
   
  The Tax Reform Act also makes interest on certain "private-activity bonds" an
item of tax preference subject to the alternative minimum tax on individuals and
corporations. The Fund invests a portion of its assets in municipal securities
subject to this provision so that a portion of its exempt-interest dividends is
an item of tax preference to the extent such dividends represent interest
received from these private-activity bonds. Accordingly, investment in the Fund
could cause shareholders to be subject to (or result in an increased liability
under) the alternative minimum tax. The Tax Reform Act also imposed per capita
volume limitations on certain private-activity bonds which could limit the
amount of such bonds available for investment by the Fund.
    
 
   
  Exempt-interest dividends are included in determining what portion, if any, of
a person's social security and railroad retirement benefits will be includable
in gross income subject to federal income tax.
    
 
   
  Although exempt-interest dividends generally may be treated by Fund
shareholders as items of interest excluded from their gross income, each
shareholder is advised to consult his tax adviser with respect to whether
exempt-interest dividends retain this exclusion if the purchaser would be
treated as a "substantial user" (or a
    
 
                                       48
<PAGE>   406
 
   
"related person" of a substantial user) of the facilities financed with respect
to any of the tax-exempt obligations held by the Fund, or by the Trust if it is
required to qualify as a regulated investment company as described below.
"Substantial user" is defined under U.S. Treasury Regulations to include a
non-exempt person who regularly uses in his trade or business a part of any
facilities financed with the tax-exempt obligations and whose gross revenues
derived from such facilities exceed five percent of the total revenues derived
from the facilities by all users, or who occupies more than 5% of the useable
area of the facilities or for whom the facilities or a part thereof were
specifically constructed, reconstructed or acquired. Examples of "related
persons" include certain related natural persons, affiliated corporations, a
partnership and its partners and an S corporation and its shareholders.
    
 
   
  The Omnibus Budget Reconciliation Act of 1993 included certain provisions that
requires gains on dispositions of tax-exempt securities purchased at a market
discount be treated as ordinary income to the extent of the accrued market
discount, if the securities are acquired after April 30, 1993. Such securities
were exempt from the market discount rules under prior law. Interest on
indebtedness incurred or continued by a shareholder to purchase or carry shares
of the Fund is not deductible for federal income tax purposes if the Fund
distributes exempt-interest dividends during the shareholder's taxable year. If
a shareholder receives an exempt-interest dividend with respect to any shares
and such shares are held for six months or less, any short-term capital loss on
the sale or exchange of the shares will be disallowed to the extent of the
amount of such exempt-interest dividend.
    
 
   
  While the Fund expects that a major portion of its net investment income will
constitute tax-exempt interest, a significant portion may consist of investment
company taxable income. Distributions of the Fund's net investment company
taxable income are taxable to shareholders as ordinary income to the extent of
the Fund's earnings and profits, whether paid in cash or reinvested in
additional shares. Distributions of the Fund's net capital gains ("capital gains
dividends"), if any, are taxable to shareholders as long-term capital gains
regardless of the length of time shares of the Fund have been held by such
shareholders. Interest on indebtedness which is incurred to purchase or carry
shares of a mutual fund which distributes exempt-interest dividends during the
year is not deductible for federal income tax purposes. Distributions in excess
of the Fund's earnings and profits will first reduce the adjusted tax basis of a
holder's shares and, after such adjusted tax basis is reduced to zero, will
constitute capital gains to such holder (assuming such shares are held as a
capital asset). Tax-exempt shareholders not subject to federal income tax on
their income generally will not be taxed on distributions from the Fund.
    
 
   
  Shareholders receiving distributions in the form of additional shares issued
by the Fund will be treated for federal income tax purposes as receiving a
distribution in an amount equal to the fair market value of the shares received,
determined as of the distribution date. The basis of such shares will equal the
fair market value on the distribution date.
    
 
                                       49
<PAGE>   407
 
   
  The Fund will inform shareholders of the source and tax status of all
distributions promptly after the close of each calendar year. The aggregate
amount of dividends so designated cannot exceed, however, the amount of interest
exempt from tax under Section 103 of the Code received by the Fund during the
year over any amounts disallowed as deductions under Sections 265 and 171(a)(2)
of the Code. Since the percentage of dividends which are "exempt-interest"
dividends is determined on an average annual method for the fiscal year, the
percentage of income designated as tax-exempt for any particular dividend may be
substantially different from the percentage of the Fund's income that was tax
exempt during the period covered by the dividend, Fund distributions generally
will not qualify for the dividends received deduction for corporations.
    
 
   
  Although dividends generally will be treated as distributed when paid,
dividends declared in October, November or December, payable to shareholders of
record on a specified date in such month and paid during January of the
following year will be treated as having been distributed by the Fund and
received by the shareholders on the December 31 prior to the date of payment. In
addition, certain other distributions made after the close of a taxable year of
the Fund may be "spilled back" and treated as paid by the Fund (except for
purposes of the 4% excise tax) during such taxable year. In such case,
shareholders will be treated as having received such dividends in the taxable
year in which the distribution was actually made.
    
 
   
  The Fund is required, in certain circumstances, to withhold 31% of dividends
and certain other payments, including redemptions, paid to shareholders who do
not furnish to the Fund their correct taxpayer identification number (in the
case of individuals, their social security number) and certain required
certifications or who are otherwise subject to backup withholding.
    
 
   
  SALE OF SHARES.  The sale of shares (including transfers in connection with a
redemption or repurchase of shares) will be a taxable transaction for federal
income tax purposes. Selling shareholders will generally recognize gain or loss
in an amount equal to the difference between their adjusted tax basis in the
shares and the amount received. If such shares are held as a capital asset, the
gain or loss will be a capital gain or loss and will be long-term if such shares
have been held for more than one year. Any loss realized upon a taxable
disposition of shares held for six months or less will be treated as a long-term
capital loss to the extent of any capital gains dividends received with respect
to such shares. For purposes of determining whether shares have been held for
six months or less, the holding period is suspended for any periods during which
the shareholder's risk of loss is diminished as a result of holding one or more
other positions in substantially similar or related property or through certain
options or short sales.
    
 
   
  GENERAL.  The federal, state and local income tax discussion set forth above
is for general information only. Prospective investors should consult their
advisors regarding the specific federal tax consequences of holding and
disposing of shares, as well as the effects of state, local and foreign tax law
and any proposed tax law changes.

DESCRIPTION OF SHARES OF THE FUND
- ------------------------------------------------------------------------------
 
  The Fund is a series of the Van Kampen American Capital Tax Free Trust, a
Delaware business trust organized as of May 10, 1995 (the "Trust"). The Fund was
originally organized in 1994 under the name Van Kampen Merritt New York Tax Free
Income Fund as a sub-trust of Van Kampen Merritt Tax Free Fund, a Massachusetts
business trust. The Fund was reorganized as a series of the Trust as of July 31,
1995. Shares of the Trust entitle their holders to one vote per share; however,
separate votes are taken by each series on matters affecting an individual
series.
 
   
  The authorized capitalization of the Fund consists of an unlimited number of
shares of beneficial interest, $0.01 par value, divided into three classes,
designated Class A Shares, Class B Shares and Class C Shares. Each class of
shares represents an interest in the same assets of the Fund and are identical
in all respects except that each class bears certain distribution expenses and
has exclusive voting rights with respect to its distribution fee. See
"Distribution and Service Plans."
    
 
   
  The Fund is permitted to issue an unlimited number of classes of shares. Each
class of shares is equal as to earnings, assets and voting privileges, except as
noted above, and each class bears the expenses related to the distribution of
its shares. There are no conversion, preemptive or other subscription rights,
except with respect to the conversion of Class B Shares and certain Class C
Shares into Class A Shares as described above. In the event of liquidation, each
of the shares of the Fund is entitled to its portion of all of the Fund's net
assets after all debt and expenses of the Fund have been paid. Since Class B
Shares and Class C Shares pay higher distribution expenses, the liquidation
proceeds to holders of Class B Shares and Class C Shares are likely to be lower
than to other shareholders.
    
 
  The Trust does not contemplate holding regular meetings of shareholders to
elect Trustees or otherwise. However, the holders of 10% or more of the
outstanding shares may by written request require a meeting to consider the
removal of Trustees by a vote of two-thirds of the shares then outstanding cast
in person or by proxy at such meeting. The Trust will assist such holders in
communicating with other shareholders of the Fund to the extent required by the
1940 Act. More detailed information concerning the Trust is set forth in the
Statement of Additional Information.

                             THE FUND AND THE TRUST
 
   
  Van Kampen American Capital Tax Free High Income Fund (the "Fund") is a
separate diversified series of the Trust. The Trust is an unincorporated
business trust established under the laws of the State of Delaware by an
Agreement and Declaration of Trust dated as of May 10, 1995 ("Declaration of
Trust"). At present, the Fund, Van Kampen American Capital Insured Tax Free
Income Fund, Van Kampen American Capital California Insured Tax Free Fund, Van
Kampen American Capital Municipal Income Fund, Van Kampen American Capital
Intermediate Term Municipal Income Fund, Van Kampen American Capital Florida
Insured Tax Free Income Fund, Van Kampen American Capital New Jersey Tax Free
Income Fund and Van Kampen American Capital New York Tax Free Income Fund have
been organized as series of the Trust and have commenced investment operations.
Van Kampen American Capital California Tax Free Income Fund, Van Kampen Merritt
American Capital Michigan Tax Free Income Fund, Van Kampen American Capital
Missouri Tax Free Income Fund and Van Kampen American Capital Ohio Tax Free
Income Fund have been organized as series of the Trust but have not commenced
investment operations. Other series may be organized and offered in the future.
The Fund originally was organized as a Maryland corporation under the name Van
Kampen Merritt Tax Free High Income Fund Inc. and was reorganized under the name
Van Kampen Merritt Tax Free High Income Fund as a sub-trust of the Van Kampen
Merritt Tax Free Fund, a Massachusetts business trust. The Fund was reorganized
as a series of the Trust and adopted its present name as of July 31, 1995.
    
 
  The Declaration of Trust permits the Trustees to create one or more separate
investment portfolios and issue a series of shares for each portfolio. The
Trustees can further sub-divide each series of shares into one or more classes
of shares for each portfolio. The Trust can issue an unlimited number of shares,
$0.01 par value (prior to July 31, 1995, the shares had no par value). Each
share of the Trust represents an equal proportionate interest in the assets of
its respective series with each other share in such series and no interest in
any other series. No series is subject to the liabilities of any other series.
The Declaration of Trust provides that shareholders are not liable for any
liabilities of the Trust or any of its series, requires inclusion of a clause to
that effect in every agreement entered into by the Trust or any of its series
and indemnifies shareholders against any such liability.
 
  Shares of the Trust entitle their holders to one vote per share; however,
separate votes are taken by each series on matters affecting an individual
series. For example, a change in investment policy for a series would be voted
upon by shareholders of only the series involved. Except as described in the
Prospectus, shares do not have cumulative voting rights, preemptive rights or
any conversion or exchange rights other than those described in the prospectus.
The Trust does not contemplate holding regular meetings of shareholders to elect
Trustees or otherwise. However, the holders of 10% or more of the outstanding
shares may by written request require a meeting to consider the removal of
Trustees by a vote of two-thirds of the shares then outstanding cast in person
or by proxy at such meeting.
 
  The Trustees may amend the Declaration of Trust (including with respect to any
series) in any manner without shareholder approval, except that the Trustees may
not adopt any amendment adversely affecting the rights of shareholders of any
series without approval by a majority of the shares of each affected series
present at a meeting of shareholders (or such higher vote as may be required by
the Investment Company Act of 1940, as amended (the "1940 Act") or other
applicable law) and except that the Trustees cannot amend the Declaration of
Trust to impose any liability on shareholders, make any assessment on shares or
impose liabilities on the Trustees without approval from each affected
shareholder or Trustee, as the case may be.
 
  Statements contained in this Statement of Additional Information as to the
contents of any contract or other document referred to are not necessarily
complete, and, in each instance, reference is made to the copy of such contract
or other document filed as an exhibit to the Registration Statement of which
this Statement of Additional Information forms a part, each such statement being
qualified in all respects by such reference.
 
                      INVESTMENT POLICIES AND RESTRICTIONS
 
  The investment objective of the Fund is set forth in the Prospectus under the
caption "Investment Objectives and Policies." There can be no assurance that the
Fund will achieve its objective.
 
                                       B-2
<PAGE>   414
 
  Fundamental investment restrictions limiting the investments of the Fund
provide that the Fund may not:
 
   
   1. Purchase any securities (other than tax exempt obligations guaranteed by
      the United States Government or by its agencies or instrumentalities), if
      as a result more than 5% of the Fund's total assets (taken at current
      value) would then be invested in securities of a single issuer or if as a
      result the Fund would hold more than 10% of the outstanding voting
      securities of any single issuer, except that the Fund may purchase
      securities of other investment companies to the extent permitted by (i)
      the 1940 Act, as amended from time to time, (ii) the rules and regulations
      promulgated by the SEC under the 1940 Act, as amended from time to time,
      or (iii) an exemption or other relief from the provisions of the 1940 Act.
    
 
   
   2. Invest more than 25% of its assets in a single industry. (As described in
      the Prospectus, the Fund may from time to time invest more than 25% of its
      assets in a particular segment of the municipal bond market; however, the
      Fund will not invest more than 25% of its assets in industrial development
      bonds in a single industry), except that the Fund may purchase securities
      of other investment companies to the extent permitted by (i) the 1940 Act,
      as amended from time to time, (ii) the rules and regulations promulgated
      by the SEC under the 1940 Act, as amended from time to time, or (iii) an
      exemption or other relief from the provisions of the 1940 Act.
    
 
   3. Borrow money, except from banks for temporary purposes and then in amounts
      not in excess of 5% of the total asset value of the Fund, or mortgage,
      pledge or hypothecate any assets except in connection with a borrowing and
      in amounts not in excess of 10% of the total asset value of the Fund.
      Borrowings may not be made for investment leverage, but only to enable the
      Fund to satisfy redemption requests where liquidation of portfolio
      securities is considered disadvantageous or inconvenient. In this
      connection, the Fund will not purchase portfolio securities during any
      period that such borrowings exceed 5% of the total asset value of the
      Fund. Notwithstanding this investment restriction, the Fund may enter into
      "when issued" and "delayed delivery" transactions as described in the
      Prospectus.
 
   4. Make loans of money or property to any person, except to the extent the
      securities in which the Fund may invest are considered to be loans and
      except that the Fund may lend money or property in connection with
      maintenance of the value of, or the Fund's interest with respect to, the
      securities owned by the Fund.
 
   5. Buy any securities "on margin." The deposit of initial or maintained
      margin in connection with interest rate or other financial futures or
      index contracts or related options is not considered the purchase of a
      security on margin.
 
   6. Sell any securities "short," write, purchase or sell puts, calls or
      combinations thereof, or purchase or sell interest rate or other financial
      futures or index contracts or related options, except as hedging
      transactions in accordance with the requirements of the Securities and
      Exchange Commission and the Commodity Futures Trading Commission.
 
   7. Act as an underwriter of securities, except to the extent the Fund may be
      deemed to be an underwriter in connection with the sale of securities held
      in their respective portfolios.
 
   
   8. Make investments for the purpose of exercising control or participation in
      management, except to the extent that exercise by the Fund of its rights
      under agreements related to securities owned by the Fund would be deemed
      to constitute such control or participation, except that the Fund may
      purchase securities of other investment companies to the extent permitted
      by (i) the 1940 Act, as amended from time to time, (ii) the rules and
      regulations promulgated by the SEC under the 1940 Act, as amended from
      time to time, or (iii) an exemption or other relief from the provisions of
      the 1940 Act.
    
 
   
   9. Invest in securities issued by other investment companies except as part
      of a merger, reorganization or other acquisition and extent permitted by
      (i) the 1940 Act, as amended from time to time, (ii) the rules and
      regulations promulgated by the SEC under the 1940 Act, as amended from
      time to time, or (iii) an exemption or other relief from the provisions of
      the 1940 Act.
    
 
  10. Invest in equity interests in oil, gas or other mineral exploration of
      development programs.
 
  11. Purchase or sell real estate, commodities or commodity contracts, except
      to the extent the securities the Fund may invest in are considered to be
      interest in real estate, commodities or commodity contracts or to the
      extent the Fund exercises its rights under agreements relating to such
      securities (in which case the Fund may own, hold, foreclose, liquidate or
      otherwise dispose of real estate acquired as a result of a default on a
      mortgage), and except to the extent the options and futures and index
      contracts in which
 
                                       B-3
<PAGE>   415
 
      such Funds may invest for hedging and risk management purposes are
      considered to be commodities or commodities contracts.
 
  The Fund may not change any of these investment restrictions nor any other
fundamental policy as they apply to the Fund without the approval of the lesser
of (i) more than 50% of the Fund's outstanding shares or (ii) 67% of the Fund's
shares present at a meeting at which the holders of more than 50% of the
outstanding shares are present in person or by proxy. As long as the percentage
restrictions described above are satisfied at the time of the investment or
borrowing, the Fund will be considered to have abided by those restrictions even
if, at a later time, a change in values or net assets causes an increase or
decrease in percentage beyond that allowed. Certain of the medium and lower
grade municipal securities in which the Fund may invest may be, subsequent to
the Fund's investment in such securities, downgraded by Moody's or S&P or may be
deemed by the Adviser to be of a lower quality as a result of impairment of the
creditworthiness of the issuer of such securities or of the project the revenues
from which are the source of payment of interest and repayment of principal with
respect to such securities. In such instances, the secondary market for such
municipal securities may become less liquid, with the possibility that more than
10% of the Fund's assets would be invested in securities which are not readily
marketable. In such event, the Fund will take reasonable and appropriate steps
to reduce the percentage of the Fund's portfolio represented by securities that
are not readily marketable, together with any other securities subject to
investment restriction eight above, to less than 10% of the Fund's assets as
soon as is reasonably practicable.
 
  The Fund generally will not engage in the trading of securities for the
purpose of realizing short-term profits, but it will adjust its portfolio as
deemed advisable in view of prevailing or anticipated market conditions to
accomplish the Fund's investment objectives. For example, the Fund may sell
portfolio securities in anticipation of a movement in interest rates. Frequency
of portfolio turnover will not be a limiting factor if the Fund considers it
advantageous to purchase or sell securities. Portfolio turnover is calculated by
dividing the lesser of purchases or sales of portfolio securities by the monthly
average value of the securities in the portfolio during the year. Securities,
including options, whose maturity or expiration date at the time of acquisition
were one year or less are excluded from such calculation. The Fund anticipates
that its annual portfolio turnover rate will normally be less than 100%.
 
  Interest on certain "private activity" obligations issued after August 7, 1986
is treated as a preference item for the purpose of calculating the alternative
minimum tax. The Fund may invest up to 20% of its assets in such "private
activity" obligations. To the extent that the Fund does invest, in such "private
activity" obligations, dividends paid to an investor who is subject to the
alternative minimum tax might not be completely tax exempt or might cause an
investor to be subject to such tax.
 
                      ADDITIONAL INVESTMENT CONSIDERATIONS
 
MUNICIPAL SECURITIES.
 
  Municipal securities include long-term obligations, which are often called
municipal bonds, as well as shorter term municipal notes, municipal leases, and
tax-exempt commercial paper. Under normal market conditions, longer term
municipal securities generally provide a higher yield than shorter term
municipal securities, and therefore the Fund generally expects to be invested
primarily in longer term municipal securities. The Fund will, however, invest in
shorter term municipal securities when yields are greater than yields available
on longer term municipal securities, for temporary defensive purposes and when
redemption requests are expected. The two principal classifications of municipal
bonds are "general obligation" and "revenue" or "special obligation" bonds,
which include "industrial revenue bonds." General obligation bonds are secured
by the issuer's pledge of its faith, credit, and taxing power for the payment of
principal and interest. Revenue or special obligation bonds are payable only
from the revenues derived from a particular facility or class of facilities or,
in some cases, from the proceeds of a special tax or other specific revenue
source such as from the user of the facility being financed. Municipal leases
are obligations issued by state and local governments or authorities to finance
the acquisition of equipment and facilities. They may take the form of a lease,
an installment purchase contract, a conditional sales contract, or a
participation certificate in any of the above. Some municipal leases and
participation certificates may not be considered readily marketable. Such
non-marketable municipal leases, together with other restricted or
non-marketable securities in the Fund's portfolio will not at the time of
purchase exceed 10% of the total assets of the Fund. The "issuer" of
 
                                       B-4
<PAGE>   416
 
municipal securities is generally deemed to be the governmental agency,
authority, instrumentality or other political subdivision, or the
non-governmental user of a facility, the assets and revenues of which will be
used to meet the payment obligations, or the guarantee of such payment
obligations, of the municipal securities.
 
  The Fund may purchase floating and variable rate demand notes, which are
municipal securities normally having a stated maturity in excess of one year,
but which permit the holder to demand payment of principal at any time, or at
specified intervals. The issuer of such notes normally has a corresponding
right, after a given period, to prepay at its discretion upon notice to the
noteholders the outstanding principal amount of the notes plus accrued interest.
The interest rate on a floating rate demand note is based on a known lending
rate, such as a bank's prime rate, and is adjusted automatically each time such
rate is adjusted. The interest rate on a variable rate demand note is adjusted
automatically at specified intervals. There generally is no secondary market for
these notes, although they are redeemable at face value. Each note purchase by
the Fund will meet the criteria established for the purchase of municipal
securities.
 
  The Fund also may invest up to 15% of its total assets in derivative variable
rate municipal securities such as inverse floaters whose rates vary inversely
with changes in market rates of interest. Such derivative variable rate
municipal securities may pay a rate of interest determined by applying a
multiple to the variable rate. The extent of increases and decreases in the
value of derivative municipal securities whose rates vary inversely with changes
in market rates of interest in response to such changes in market rates
generally will be larger than comparable changes in the value of an equal
principal amount of a fixed rate municipal security having similar credit
quality, redemption provisions and maturity. In addition, the Fund may invest in
derivative municipal securities the terms of which include elements of, or are
similar in effect to, certain Strategic Transactions in which the Fund may
engage. Such municipal securities may by their terms, for example, have economic
characteristics comparable to, among other things, a swap, cap, floor or collar
transaction with respect to such security for a period of time prior to its
stated maturity. See "Additional Investment Considerations -- Strategic
Transactions" in this Statement of Additional Information.
 
  MEDIUM AND LOWER GRADE MUNICIPAL SECURITIES.  Discussion concerning the
special risk factors relating to the Fund's investments in medium and lower
grade municipal securities appears in the "Municipal Securities" section of the
Prospectus under the subheading "Special Considerations and Risk Factors
Regarding Medium and Lower Grade Municipal Securities."
 
INVESTMENT PRACTICES.
 
  If the Adviser deems it appropriate to seek to hedge any of the Fund's
portfolio against market value changes, the Fund may buy or sell derivative
instruments such as financial futures contracts and related options, such as
municipal bond index futures contracts and the related put or call options
contracts on such index futures. A tax exempt bond index fluctuates with changes
in the market values of the tax exempt bonds included in the index. An index
future is an agreement pursuant to which two parties agree to receive or deliver
at settlement an amount of cash equal to a specified dollar amount multiplied by
the difference between the value of the index at the close of the last trading
day of the contract and the price at which the future was originally written. A
financial future is an agreement between two parties to buy and sell a security
for a set price on a future date. An index future has similar characteristics to
a financial future except that settlement is made through delivery of cash
rather than the underlying securities. An example is the Long-Term Municipal
Bond futures contract traded on the Chicago Board of Trade. It is based on the
Bond Buyer's Municipal Bond Index, which represents an adjusted average price of
the forty most recent long-term municipal issues of $50 million or more ($75
million in the instance of housing issues) rated A or better by either Moody's
Investors Service, Inc. ("Moody's")or Standard & Poor's Ratings Group ("S&P"),
maturing in no less than nineteen years, having a first call in no less than
seven nor more than sixteen years, and callable at par.
 
  The Fund may engage in "when issued" and "delayed delivery" transactions and
utilize futures contracts and options thereon for hedging purposes. The
Securities and Exchange Commission ("SEC") generally requires that when mutual
funds, such as the Fund, effect transactions of the foregoing nature, such funds
must either segregate cash or readily marketable portfolio securities with its
custodian in an amount of its obligations under the foregoing transactions, or
cover such obligations by maintaining positions in portfolio securities, futures
contracts or options that would serve to satisfy or offset the risk of such
obligations. When
 
                                       B-5
<PAGE>   417
 
effecting transactions of the foregoing nature, the Fund will comply with such
segregation or cover requirements.
 
  When the Fund engages in the purchase or sale of futures contracts or the sale
of options thereon it will deposit the initial margin required for such
contracts in a segregated account maintained with the Fund's custodian, in the
name of the futures commission merchant with whom the Fund maintains the related
account. Thereafter, if the Fund is required to make maintenance margin payments
with respect to the futures contracts, or mark-to-market payments with respect
to such option sale positions, the Fund will make such payments directly to such
futures commission merchant. The SEC currently requires mutual funds to demand
promptly the return of any excess maintenance margin or mark-to- market credits
in its account with futures commission merchants. Each Fund will comply with SEC
requirements concerning such excess margin.
 
  The Fund may invest up to 15% of its total assets in illiquid securities,
securities the disposition of which is subject to substantial legal or
contractual restrictions on resale and securities that are not readily
marketable. The sale of restricted and illiquid securities often requires more
time and results in higher brokerage charges or dealer discounts and other
selling expenses than does the sale of securities eligible for trading on
national securities exchanges or in the over-the-counter markets. Restricted
securities may sell at a price lower than similar securities that are not
subject to restrictions on resale. Restricted securities salable among qualified
institutional buyers without restriction pursuant to Rule 144A under the
Securities Act of 1933, as amended, that are determined to be liquid by the
Adviser under guidelines adopted by the Board of Trustees of the Trust (under
which guidelines the Adviser will consider factors such as trading activities
and the availability of price quotations), will not be treated as restricted
securities by the Fund pursuant to such rules. The Fund may, from time to time,
adopt a more restrictive limitation with respect to investment in illiquid and
restricted securities in order to comply with the most restrictive state
securities law, currently 10%. This policy does not include restricted
securities eligible for resale pursuant to Rule 144A under the Securities Act of
1933, as amended, which the Board of Trustees or the Fund's investment adviser
has determined under Board-approved guidelines to be liquid.
 
STRATEGIC TRANSACTIONS.
 
  The Fund may, but is not required to, utilize various other investment
strategies as described below to hedge various market risks (such as interest
rates and broad or specific market movements) or to manage the effective
maturity or duration of the Fund's fixed-income securities. Such strategies are
generally accepted by modern portfolio managers and are regularly utilized by
many mutual funds and other institutional investors. Techniques and instruments
may change over time as new instruments and strategies are developed or
regulatory changes occur.
 
  In the course of pursuing these investment strategies, the Fund may purchase
and sell derivative instruments such as exchange-listed and over-the-counter put
and call options on securities, fixed-income indices and other financial
instruments, purchase and sell financial futures contracts and options thereon,
enter into various interest rate transactions such as swaps, caps, floors or
collars (collectively, all the above are called "Strategic Transactions").
Strategic Transactions may be used to attempt to protect against possible
changes in the market value of securities held in or to be purchased for the
Fund's portfolio resulting from securities markets fluctuations, to protect the
Fund's unrealized gains in the value of its portfolio securities, to facilitate
the sale of such securities for investment purposes, to manage the effective
maturity or duration of the Fund's portfolio, or to establish a position in the
derivatives markets as a temporary substitute for purchasing or selling
particular securities.
 
  Any or all of these investment techniques may be used at any time and there is
no particular strategy that dictates the use of one technique rather than
another, as use of any Strategic Transaction is a function of numerous variables
including market conditions. The ability of the Fund to utilize these Strategic
Transactions successfully will depend on the Adviser's ability to predict
pertinent market movements, which cannot be assured. The Fund will comply with
applicable regulatory requirements when implementing these strategies,
techniques and instruments. Strategic Transactions involving financial futures
and options thereon will be purchased, sold or entered into only for bona fide
hedging, risk management or portfolio management purposes and not for
speculative purposes.
 
                                       B-6
<PAGE>   418
 
  Strategic Transactions have risks associated with them including possible
default by the other party to the transaction, illiquidity and, to the extent
the Adviser's view as to certain market movements is incorrect, the risk that
the use of such Strategic Transactions could result in losses greater than if
they had not been used. Use of put and call options may result in losses to the
Fund, force the sale or purchase of portfolio securities at inopportune times or
for prices other than current market values, limit the amount of appreciation
the Fund can realize on its investments or cause the Fund to hold a security it
might otherwise sell. The use of options and futures transactions entails
certain other risks. In particular, the variable degree of correlation between
price movements of futures contracts and price movements in the related
portfolio position of the Fund creates the possibility that losses on the
hedging instrument may be greater than gains in the value of the Fund's
position. In addition, futures and options markets may not be liquid in all
circumstances and certain over-the-counter options may have no markets. As a
result, in certain markets, the Fund might not be able to close out a
transaction without incurring substantial losses, if at all. Although the use of
futures and options transactions for hedging should tend to minimize the risk of
loss due to a decline in the value of the hedged position, at the same time they
tend to limit any potential gain which might result from an increase in value of
such position. Finally, the daily variation margin requirements for futures
contracts would create a greater ongoing potential financial risk than would
purchases of options, where the exposure is limited to the cost of the initial
premium. Losses resulting from the use of Strategic Transactions would reduce
net asset value, and possibly income, and such losses can be greater than if the
Strategic Transactions had not been utilized. Income earned or deemed to be
earned, if any, by the Fund from its Strategic Transactions will generally be
taxable income of the Fund. See "Tax Status" in the Prospectus.
 
  GENERAL CHARACTERISTICS OF OPTIONS.   Put options and call options typically
have similar structural characteristics and operational mechanics regardless of
the underlying instrument on which they are purchased or sold. Thus, the
following general discussion relates to each of the particular types of options
discussed in greater detail below. In addition, many Strategic Transactions
involving options require segregation of Fund assets in special accounts, as
described below under "Use of Segregated and Other Special Accounts."
 
  A put option gives the purchaser of the option, upon payment of a premium, the
right to sell, and the writer the obligation to buy, the underlying security,
commodity, index, or other instrument at the exercise price. For instance, the
Fund's purchase of a put option on a security might be designed to protect its
holdings in the underlying instrument (or, in some cases, a similar instrument)
against a substantial decline in the market value by giving the Fund the right
to sell such instrument at the option exercise price. A call option, upon
payment of a premium, gives the purchaser of the option the right to buy, and
the seller the obligation to sell, the underlying instrument at the exercise
price. The Fund's purchase of a call option on a security, financial future,
index, or other instrument might be intended to protect the Fund against an
increase in the price of the underlying instrument that it intends to purchase
in the future by fixing the price at which it may purchase such instrument. An
American style put or call option may be exercised at any time during the option
period while a European style put or call option may be exercised only upon
expiration or during a fixed period prior thereto. The Fund is authorized to
purchase and sell exchange listed options and over-the-counter options ("OTC
options"). Exchange listed options are issued by a regulated intermediary such
as the Options Clearing Corporation ("OCC"), which guarantees the performance of
the obligations of the parties to such options. The discussion below uses the
OCC as a paradigm, but is also applicable to other financial intermediaries.
 
  With certain exceptions, OCC issued and exchange listed options generally
settle by physical delivery of the underlying security or currency, although in
the future cash settlement may become available. Index options and Eurodollar
instruments are cash settled for the net amount, if any, by which the option is
"in-the-money" (i.e., where the value of the underlying instrument exceeds, in
the case of a call option, or is less than, in the case of a put option, the
exercise price of the option) at the time the option is exercised. Frequently,
rather than taking or making delivery of the underlying instrument through the
process of exercising the option, listed options are closed by entering into
offsetting purchase or sale transactions that do not result in ownership of the
new option.
 
  The Fund's ability to close out its position as a purchaser or seller of an
OCC or exchange listed put or call option is dependent, in part, upon the
liquidity of the option market. Among the possible reasons for the
 
                                       B-7
<PAGE>   419
 
absence of a liquid option 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
including reaching daily price limits; (iv) interruption of the normal
operations of the OCC or an exchange; (v) inadequacy of the facilities of an
exchange or 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 relevant market for that option on that
exchange would cease to exist, although outstanding options on that exchange
would generally continue to be exercisable in accordance with their terms.
 
  The hours of trading for listed options may not coincide with the hours during
which the underlying financial instruments are traded. To the extent that the
option markets close before the markets for the underlying financial
instruments, significant price and rate movements can take place in the
underlying markets that cannot be reflected in the option markets.
 
  OTC options are purchased from or sold to securities dealers, financial
institutions or other parties ("Counterparties") through direct bilateral
agreement with the Counterparty. In contrast to exchange listed options, which
generally have standardized terms and performance mechanics, all the terms of an
OTC option, including such terms as method of settlement, term, exercise price,
premium, guarantees and security, are set by negotiation of the parties. The
Fund will only sell OTC options that are subject to a buy-back provision
permitting the Fund to require the Counterparty to sell the option back to the
Fund at a formula price within seven days. The Fund expects generally to enter
into OTC options that have cash settlement provisions, although it is not
required to do so.
 
  Unless the parties provide for it, there is no central clearing or guaranty
function in an OTC option. As a result, if the Counterparty fails to make or
take delivery of the security, or other instrument underlying an OTC option it
has entered into with the Fund or fails to make a cash settlement payment due in
accordance with the terms of that option, the Fund will lose any premium it paid
for the option as well as any anticipated benefit of the transaction.
Accordingly, the Adviser must assess the creditworthiness of each such
Counterparty or any guarantor or credit enhancement of the Counterparty's credit
to determine the likelihood that the terms of the OTC option will be satisfied.
The Fund will engage in OTC option transactions only with United States
government securities dealers recognized by the Federal Reserve Bank of New York
as "primary dealers", or broker dealers, domestic or foreign banks or other
financial institutions which have received (or the guarantors of the obligation
of which have received) a short-term credit rating of "A-1" from S&P or "P-1"
from Moody's or an equivalent rating from any other nationally recognized
statistical rating organization ("NRSRO"). The staff of the SEC currently takes
the position that, in general, OTC options on securities other than U.S.
Government securities purchased by the Fund, and portfolio securities "covering"
the amount of the Fund's obligation pursuant to an OTC option sold by it (the
cost of the sell-back plus the in-the-money amount, if any) are illiquid, and
are subject to the Fund's limitation on investing no more than 15% of its assets
in illiquid securities.
 
  If the Fund sells a call option, the premium that it receives may serve as a
partial hedge, to the extent of the option premium, against a decrease in the
value of the underlying securities or instruments in its portfolio or will
increase the Fund's income. The sale of put options can also provide income.
 
  The Fund may purchase and sell call options on securities, including U.S.
Treasury and agency securities, municipal obligations, mortgage-backed
securities and Eurodollar instruments that are traded on U.S. and foreign
securities exchanges and in the over-the-counter markets. All calls sold by the
Fund must be "covered" (i.e., the Fund must own the securities or futures
contract subject to the call) or must meet the asset segregation requirements
described below as long as the call is outstanding. Even though the Fund will
receive the option premium to help protect it against loss, a call sold by the
Fund exposes the Fund during the term of the option to possible loss of
opportunity to realize appreciation in the market price of the underlying
security or instrument and may require the Fund to hold a security or instrument
which it might otherwise have sold.
 
  The Fund may purchase and sell put options on securities including U.S.
Treasury and agency securities, mortgage-backed securities, municipal
obligations and Eurodollar instruments (whether or not it holds the above
securities in its portfolio.) The Fund will not sell put options if, as a
result, more than 50% of the Fund's
 
                                       B-8
<PAGE>   420
 
assets would be required to be segregated to cover its potential obligations
under such put options other than those with respect to futures and options
thereon. In selling put options, there is a risk that the Fund may be required
to buy the underlying security at a disadvantageous price above the market
price.
 
  GENERAL CHARACTERISTICS OF FUTURES.  The Fund may enter into financial futures
contracts or purchase or sell put and call options on such futures as a hedge
against anticipated interest rate or fixed-income market changes, for duration
management and for risk management purposes. Futures are generally bought and
sold on the commodities exchanges where they are listed with payment of initial
and variation margin as described below. The purchase of a futures contract
creates a firm obligation by the Fund, as purchaser, to take delivery from the
seller the specific type of financial instrument called for in the contract at a
specific future time for a specified price (or, with respect to index futures
and Eurodollar instruments, the net cash amount). The sale of a futures contract
creates a firm obligation by the Fund, as seller, to deliver to the buyer the
specific type of financial instrument called for in the contract at a specific
future time for a specified price (or, with respect to index futures and
Eurodollar instruments, the net cash amount). Options on futures contracts are
similar to options on securities except that 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 and obligates the seller to deliver such option.
 
  The Fund's use of financial futures and options thereon will in all cases be
consistent with applicable regulatory requirements and in particular the rules
and regulations of the Commodity Futures Trading Commission and will be entered
into only for bona fide hedging, risk management (including duration management)
or other portfolio management purposes. Typically, maintaining a futures
contract or selling an option thereon requires the Fund to deposit with a
financial intermediary as security for its obligations an amount of cash or
other specified assets (initial margin) which initially is typically 1% to 10%
of the face amount of the contract (but may be higher in some circumstances).
Additional cash or assets (variation margin) may be required to be deposited
thereafter on a daily basis as the mark to market value of the contract
fluctuates. The purchase of options on financial futures involves payment of a
premium for the option without any further obligation on the part of the Fund.
If the Fund exercises an option on a futures contract it will be obligated to
post initial margin (and potential subsequent variation margin) for the
resulting futures position just as it would for any position. Futures contracts
and options thereon are generally settled by entering into an offsetting
transaction but there can be no assurance that the position can be offset prior
to settlement at an advantageous price nor that delivery will occur.
 
  The Fund will not enter into a futures contract or related option (except for
closing transactions) if, immediately thereafter, the sum of the amount of its
initial margin and premiums on open futures contracts and options thereon would
exceed 5% of the Fund's total assets (taken at current value); however, in the
case of an option that is in-the-money at the time of the purchase, the
in-the-money amount may be excluded in calculating the 5% limitation. The
segregation requirements with respect to futures contracts and options thereon
are described below.
 
  OPTIONS ON SECURITIES INDICES AND OTHER FINANCIAL INDICES.  The Fund also may
purchase and sell call and put options on securities indices and other financial
indices and in so doing can achieve many of the same objectives it would achieve
through the sale or purchase of options on individual securities or other
instruments. Options on securities indices and other financial indices are
similar to options on a security or other instrument except that, rather than
settling by physical delivery of the underlying instrument, they settle by cash
settlement, i.e., an option on an index gives the holder the right to receive,
upon exercise of the option, an amount of cash if the closing level of the index
upon which the option is based exceeds, in the case of a call, or is less than,
in the case of a put, the exercise price of the option (except if, in the case
of an OTC option, physical delivery is specified). This amount of cash is equal
to the excess of the closing price of the index over the exercise price of the
option, which also may be multiplied by a formula value. The seller of the
option is obligated, in return for the premium received, to make delivery of
this amount. The gain or loss on an option on an index depends on price
movements in the instruments making up the market, market segment, industry or
other composite on which the underlying index is based, rather than price
movements in individual securities, as is the case with respect to options on
securities.
 
  COMBINED TRANSACTIONS.  The Fund may enter into multiple transactions,
including multiple options transactions, multiple futures transactions and
multiple interest rate transactions and any combination of
 
                                       B-9
<PAGE>   421
 
futures, options and interest rate transactions ("component" transactions),
instead of a single Strategic Transaction, as part of a single or combined
strategy when, in the opinion of the Adviser, it is in the best interests of the
Fund to do so. A combined transaction will usually contain elements of risk that
are present in each of its component transactions. Although combined
transactions are normally entered into based on the Adviser's judgment that the
combined strategies will reduce risk or otherwise more effectively achieve the
desired portfolio management goal, it is possible that the combination will
instead increase such risks or hinder achievement of the portfolio management
objective.
 
  SWAPS, CAPS, FLOORS AND COLLARS.  Among the Strategic Transactions into which
the Fund may enter are interest rate and index swaps and the purchase or sale of
related caps, floors and collars. The Fund expects to enter into these
transactions primarily to preserve a return or spread on a particular investment
or portion of its portfolio, as a duration management technique or to protect
against any increase in the price of securities the Fund anticipates purchasing
at a later date. The Fund intends to use these transactions as hedges and not as
speculative investments and will not sell interest rate caps or floors where it
does not own securities or other instruments providing the income stream the
Fund may be obligated to pay. Interest rate swaps involve the exchange by the
Fund with another party of their respective commitments to pay or receive
interest, e.g., an exchange of floating rate payments for fixed rate payments
with respect to a notional amount of principal. An index swap is an agreement to
swap cash flows on a notional amount based on changes in the values of the
reference indices. The purchase of a cap entitles the purchaser to receive
payments on a notional principal amount from the party selling such cap to the
extent that a specified index exceeds a predetermined interest rate or amount.
The purchase of a floor entitles the purchaser to receive payments on a notional
principal amount from the party selling such floor to the extent that a
specified index falls below a predetermined interest rate or amount. A collar is
a combination of a cap and a floor that preserves a certain return within a
predetermined range of interest rates or values.
 
  The Fund will usually enter into swaps on a net basis, i.e., the two payment
streams are netted out in a cash settlement on the payment date or dates
specified in the instrument, with the Fund receiving or paying, as the case may
be, only the net amount of the two payments. Inasmuch as these swaps, caps,
floors and collars are entered into for good faith hedging purposes, the Adviser
and the Fund believe such obligations do not constitute senior securities under
the 1940 Act and, accordingly, will not treat them as being subject to its
borrowing restrictions. The Fund will not enter into any swap, cap, floor or
collar transaction unless, at the time of entering into such transaction, the
unsecured long-term debt of the Counterparty, combined with any credit
enhancements, is rated at least "A" by S&P or Moody's or has an equivalent
equity rating from an NRSRO or is determined to be of equivalent credit quality
by the Adviser. If there is a default by the Counterparty, the Fund may have
contractual remedies pursuant to the agreements related to the transaction. The
swap market has grown substantially in recent years with a large number of banks
and investment banking firms acting both as principals and agents utilizing
standardized swap documentation. As a result, the swap market has become
relatively liquid. Caps, floors and collars are more recent innovations for
which standardized documentation has not yet been fully developed and,
accordingly, they are less liquid than swaps.
 
   
  USE OF SEGREGATED AND OTHER SPECIAL ACCOUNTS.  Many Strategic Transactions, in
addition to other requirements, require that the Fund segregate liquid
high-grade assets with its custodian to the extent Fund obligations are not
otherwise "covered" through ownership of the underlying security, financial
instrument or currency. In general, either the full amount of any obligation by
the Fund to pay or deliver securities or assets must be covered at all times by
the securities, instruments or currency required to be delivered, or, subject to
any regulatory restrictions, an amount of cash or liquid securities at least
equal to the current amount of the obligation must be segregated with the
custodian. The segregated assets cannot be sold or transferred unless equivalent
assets are substituted in their place or it is no longer necessary to segregate
them. For example, a call option written by the Fund will require the Fund to
hold the securities subject to the call (or securities convertible into the
needed securities without additional consideration) or to segregate liquid
securities sufficient to purchase and deliver the securities if the call is
exercised. A call option sold by the Fund on an index will require the Fund to
own portfolio securities which correlate with the index or to segregate liquid
securities equal to the excess of the index value over the exercise price on a
current basis. A put option written by the Fund requires the Fund to segregate
liquid securities assets equal to the exercise price.
    
 
                                      B-10
<PAGE>   422
 
  OTC options entered into by the Fund, including those on securities, financial
instruments or indices and OCC issued and exchange listed index options, will
generally provide for cash settlement. As a result, when the Fund sells these
instruments it will only segregate an amount of assets equal to its accrued net
obligations, as there is no requirement for payment or delivery of amounts in
excess of the net amount. These amounts will equal 100% of the exercise price in
the case of a non cash-settled put, the same as an OCC guaranteed listed option
sold by the Fund, or the in-the-money amount plus any sell-back formula amount
in the case of a cash-settled put or call. In addition, when the Fund sells a
call option on an index at a time when the in-the-money amount exceeds the
exercise price, the Fund will segregate, until the option expires or is closed
out, cash or cash equivalents equal in value to such excess. OCC issued and
exchange listed options sold by the Fund other than those above generally settle
with physical delivery, and the Fund will segregate an amount of assets equal to
the full value of the option. OTC options settling with physical delivery, or
with an election of either physical delivery or cash settlement, will be treated
the same as other options settling with physical delivery.
 
  In the case of a futures contract or an option thereon, the Fund must deposit
initial margin and possible daily variation margin in addition to segregating
assets sufficient to meet its obligation to purchase or provide securities or
currencies, or to pay the amount owed at the expiration of an index-based
futures contract. Such assets may consist of cash, cash equivalents, liquid debt
or equity securities or other acceptable assets.
 
   
  With respect to swaps, the Fund will accrue the net amount of the excess, if
any, of its obligations over its entitlements with respect to each swap on a
daily basis and will segregate an amount of cash or liquid securities having a
value equal to the accrued excess. Caps, floors and collars require segregation
of assets with a value equal to the Fund's net obligation, if any.
    
 
  Strategic Transactions may be covered by other means when consistent with
applicable regulatory policies. The Fund may also enter into offsetting
transactions so that its combined position, coupled with any segregated assets,
equals its net outstanding obligation in related options and Strategic
Transactions. For example, the Fund could purchase a put option if the strike
price of that option is the same or higher than the strike price of a put option
sold by the Fund. Moreover, instead of segregating assets if the Fund held a
futures or forward contract, it could purchase a put option on the same futures
or forward contract with a strike price as high or higher than the price of the
contract held. Other Strategic Transactions may also be offset in combinations.
If the offsetting transaction terminates at the time of or after the primary
transaction no segregation is required, but if it terminates prior to such time,
assets equal to any remaining obligation would need to be segregated.
 
  The Fund's activities involving Strategic Transactions may be limited by the
requirements of Subchapter M of the Code for qualification as a regulated
investment company. See "Tax Status" in the Prospectus.

  Each of the trustees holds the same position with each of the funds in the
Fund Complex. As of December 31, 1996, there were 51 funds in the Fund Complex.
Each trustee who is not an affiliated person of VKAC, the Advisers, the
Distributor, ACCESS or Morgan Stanley (each a "Non-Affiliated Trustee") is
compensated by an annual retainer and meeting fees for services to the funds in
the Fund Complex. Each fund in the Fund Complex provides a deferred compensation
plan to its Non-Affiliated Trustees that allows trustees to defer receipt of
their compensation and earn a return on such deferred amounts based upon the
return of the common shares of the funds in the Fund Complex as more fully
described below. Each fund in the Fund Complex also provides a retirement plan
to its Non-Affiliated Trustees that provides Non-Affiliated Trustees with
compensation after retirement, provided that certain eligibility requirements
are met as more fully described below.
    
 
   
  The compensation of each Non-Affiliated Trustee from each fund in the Fund
Complex advised by Advisory Corp. (each a "VK Fund" and collectively the "VK
Funds") includes an annual retainer in an amount equal to $2,500 per calendar
year, due in four quarterly installments on the first business day of each
calendar quarter. Each Non-Affiliated Trustee receives a per meeting fee from
each VK Fund in the amount of $125 per regular quarterly meeting attended by the
Non-Affiliated Trustee, due on the date of such meeting, plus reasonable
expenses incurred by the Non-Affiliated Trustee in connection with his or her
services as a trustee. Each Non-Affiliated Trustee receives a per meeting fee
from each VK Fund in the amount of $125 per special meeting attended by the
Non-Affiliated Trustee, due on the date of such meeting, plus reasonable
expenses incurred by the Non-Affiliated Trustee in connection with his or her
services as a trustee, provided that no compensation will be paid in connection
with certain telephonic special meetings.
    
 
   
  The compensation of each Non-Affiliated Trustee from the funds in the Fund
Complex advised by Asset Management (each an "AC Fund" or collectively the "AC
Funds") includes an annual retainer in an amount equal to $35,000 per calendar
year, due in four quarterly installments on the first business day of each
calendar quarter. The AC Funds pay each Non-Affiliated Trustee a per meeting fee
in the amount of $2,000 per regular quarterly meeting attended by the
Non-Affiliated Trustee, due on the date of such meeting, plus reasonable
expenses incurred by the Non-Affiliated Trustee in connection with his or her
services as a trustee. Payment of the annual retainer and the regular meeting
fee is allocated among the AC Funds (i) 50% on the basis of the relative net
assets of each AC Fund to the aggregate net assets of all the AC Funds and (ii)
50% equally to each AC Fund, in each case as of the last business day of the
preceding calendar quarter. Each AC Fund which is the subject of a special
meeting of the trustees generally pays each Non-Affiliated Trustee a per meeting
fee in the amount of $125 per special meeting attended by the Non-Affiliated
Trustee, due on the date of such meeting, plus reasonable expenses incurred by
the Non-Affiliated Trustee in connection with his or her services as a trustee,
provided that no compensation will be paid in connection with certain telephonic
special meetings.
    
 
   
  The trustees approved an aggregate compensation cap with respect to funds in
the Fund Complex of $84,000 per Non-Affiliated Trustee per year (excluding any
retirement benefits) for the period July 22, 1995 through December 31, 1996,
subject to the net assets and the number of funds in the Fund Complex as of July
21, 1995 and certain other exceptions. For the calendar year ended December 31,
1996, certain trustees received aggregate compensation from the funds in the
Fund Complex over $84,000 due to compensation received but not subject to the
cap, including compensation from new funds added to the Fund Complex after July
22, 1995 and certain special meetings in 1996. In addition, each of Advisory
Corp. or Asset Management, as the case may be, agreed to reimburse each fund in
the Fund Complex through December 31, 1996 for any increase in the aggregate
trustee's compensation over the aggregate compensation paid by such fund in its
1994 fiscal year, provided that if a fund did not exist for the entire 1994
fiscal year appropriate adjustments will be made.
    
 
   
  Each Non-Affiliated Trustee generally can elect to defer receipt of all or a
portion of the compensation earned by such Non-Affiliated Trustee until
retirement. Amounts deferred are retained by the Fund and earn a rate of return
determined by reference to the return on the common shares of such Fund or other
funds in the Fund Complex as selected by the respective Non-Affiliated Trustee,
with the same economic effect as if such Non-Affiliated Trustee had invested in
one or more funds in the Fund Complex. To the extent permitted by the 1940 Act,
the Fund may invest in securities of those funds selected by the Non-Affiliated
Trustees in
    
 
                                      B-16

order to match the deferred compensation obligation. The deferred compensation
plan is not funded and obligations thereunder represent general unsecured claims
against the general assets of the Fund.
    
 
   
  Each fund in the Fund Complex has adopted a retirement plan. Under the Fund's
retirement plan, a Non-Affiliated Trustee who is receiving trustee's
compensation from the Fund prior to such Non-Affiliated Trustee's retirement,
has at least 10 years of service (including years of service prior to adoption
of the retirement plan) and retires at or after attaining the age of 60, is
eligible to receive a retirement benefit equal to $2,500 per year for each of
the ten years following such trustee's retirement from the Fund. Trustees
retiring prior to the age of 60 or with fewer than 10 years but more than 5
years of service may receive reduced retirement benefits from the Fund. Each
trustee has served as a member of the Board of Trustees since he or she was
first appointed or elected in the year set forth below. The retirement plan
contains a Fund Complex retirement benefit cap of $60,000 per year. Asset
Management has reimbursed each AC Fund for the expenses related to the
retirement plan through December 31, 1996.
    
 
   
  Additional information regarding compensation and benefits for trustees is set
forth below. As indicated in the notes accompanying the table, the amounts
relate to either the Trust's most recently completed fiscal year or the Fund
Complex' most recently completed calendar year ended December 31, 1996.

   McDonnell and Powell, also trustees of the Trust during all or a portion of
   the Trust's last fiscal year, are not included in the compensation table
   because they are affiliated persons of the Advisers and are not eligible for
   compensation or retirement benefits from the Trust.

    The detail of aggregate compensation before deferral for each series,
    including the Fund, are shown in Table A below. Certain trustees deferred
    compensation from the Trust during the fiscal year ended December 31, 1996;
    the aggregate compensation deferred from all eight series of the Trust,
    including the Fund, is as follows: Mr. Branagan, $5,750; Mr. Gaughan,
    $3,750; Ms. Heagy, $15,000; Mr. Kennedy, $9,500; Mr. Miller, $20,000; Mr.
    Nelson, $20,000; Mr. Robinson, $18,000; and Mr. Whalen, $19,625. The details
    of amounts deferred for each series, including the Fund, are shown in Table

    rate of return determined by reference to either the return on the common
    shares of such fund or other funds in the Fund Complex as selected by the
    respective Non-Affiliated Trustee, with the same economic effect as if such
    Non-Affiliated Trustee had invested in one or more funds in the Fund
    Complex. To the extent permitted by the 1940 Act, each fund may invest in
    securities of those funds selected by the Non-Affiliated Trustees in order
    to match the deferred compensation obligation. The cumulative deferred
    compensation (including interest) accrued with respect to each trustee from
    all eight series of the Trust, including the Fund, as of the Trust's fiscal
    year ended December 31, 1996 is as follows: Mr. Branagan, $5,678; Mr.

    below. The retirement plan is described above the Compensation Table.
    
 
   
(4) This is the estimated maximum annual benefits payable by the Trust in each
    year of the 10-year period commencing in the year of such trustee's
    retirement from the Trust. The estimated maximum annual benefit, except for
    trustees who have retired or are near retirement, is based upon $2,500 per
    series assuming: the trustee has 10 or more years of service on the Board of
    Trustees (including years of service prior to the adoption of the retirement
    plan) and retires at or after attaining the age of 60. Trustees retiring
    prior to the age of 60 or with fewer than 10 years of service for a series
    of the Trust may receive reduced retirement benefits from such series. The
    actual annual benefit may be less if the trustee is subject to the Fund
    Complex retirement benefit cap or if the trustee is not fully vested at the
    time of retirement. Each Non-Affiliated Trustee of the Board of Trustees has
    served as a member of the Board of Trustees since he or she was first
    appointed or elected in the year set forth in Table E below.
    
 
   
(5) The amounts shown in this column represent the aggregate compensation paid
    by all 51 of the investment companies in the Fund Complex as of December 31,
    1996 before deferral by the trustees under the deferred compensation plan.
    Certain trustees deferred all or a portion of their aggregate compensation
    from the Fund Complex during the calendar year ended December 31, 1996. The
    deferred compensation earns a rate of return determined by reference to the
    return on the shares of the funds in the Fund Complex as selected by the
    respective Non-Affiliated Trustee, with the same economic effect as if such
    Non-Affiliated Trustee had invested in one or more funds in the Fund
    Complex. To the extent permitted by the 1940 Act, the Fund may invest in
    securities of those investment companies selected by the Non-Affiliated
    Trustees in order to match the deferred compensation obligation. The
    trustees' Fund Complex compensation cap covered the period July 22, 1995
    through December 31, 1996. For the calendar year ended December 31, 1996,
    certain trustees received compensation over $84,000 in the aggregate due to
    compensation received but not subject to the cap, including compensation
    from new funds added to the Fund Complex after July 22, 1995 and certain
    special meetings in 1996. The Advisers and their affiliates also serve as
    investment adviser for other investment companies; however, with the
    exception of Messrs. McDonnell, Powell and Whalen, the trustees were not
    trustees of such investment companies. Combining the Fund Complex with other
    investment companies advised by the Advisers and their affiliates, Mr.
    Whalen received Total Compensation of $243,375 during the calendar year
    ended December 31, 1996.
    
 
   
  As of April 4, 1997, the trustees and officers of the Fund as a group owned
less than 1% of the shares of the Fund.

                     INVESTMENT ADVISORY AND OTHER SERVICES
 
   
  The Adviser is the Fund's investment adviser. The Adviser was incorporated as
a Delaware corporation in 1982 (and through December 31, 1987 transacted
business under the name of American Portfolio Advisory Service Inc.).
    
 
   
  The Adviser is a wholly-owned subsidiary of Van Kampen American Capital, Inc.
("VKAC"), which is a wholly-owned subsidiary of VK/AC Holding, Inc. VK/AC
Holding, Inc. is a wholly-owned subsidiary of MSAM Holdings II, Inc. which, in
turn, is a wholly-owned subsidiary of Morgan Stanley Group Inc. The principal
office of the Fund, the Adviser, the Distributor and VKAC is located at One
Parkview Plaza, Oakbrook Terrace, Illinois 60181.
    
 
   
  Morgan Stanley Group Inc. and various of its directly or indirectly owned
subsidiaries, including Morgan Stanley & Co. Incorporated, a registered
broker-dealer and investment adviser, and Morgan Stanley International, are
engaged in a wide range of financial services. Their principal businesses
include securities underwriting, distribution and trading; merger, acquisition,
restructuring and other corporate finance advisory activities; merchant banking;
stock brokerage and research services; asset management; trading of futures,
options, foreign exchange, commodities and swaps (involving foreign exchange,
commodities, indices and interest rates); real estate advice, financing and
investing; and global custody, securities clearance services and securities
lending.
    
 
   
  On February 5, 1997, Morgan Stanley Group Inc. and Dean Witter, Discover & Co.
announced that they had entered into an Agreement and Plan of Merger to form
Morgan Stanley, Dean Witter, Discover & Co. Subject to certain conditions being
met, it is currently anticipated that the transaction will close in mid-1997.
Thereafter, Van Kampen American Capital Asset Management, Inc. will be an
indirect subsidiary of Morgan Stanley, Dean Witter, Discover & Co.
    
 
   
  Dean Witter, Discover & Co. is a financial services company with three major
businesses; full service brokerage, credit services and asset management.
    
 
   
  The investment advisory agreement provides that the Adviser will supply
investment research and portfolio management, including the selection of
securities for the Fund to purchase. The Adviser also administers the
    
 
                                      B-20
<PAGE>   432
 
business affairs of the Fund, furnishes offices, necessary facilities and
equipment, provides administrative services, and permits its officers and
employees to serve without compensation as officers of the Fund and trustees of
the Trust if duly elected to such positions.
 
  The agreement provides that the Adviser shall not be liable for any error of
judgment or of law, or for any loss suffered by the Fund in connection with the
matters to which the agreement relates, except a loss resulting from willful
misfeasance, bad faith or gross negligence on the part of the Adviser in the
performance of its obligations and duties, or by reason of its reckless
disregard of its obligations and duties under the agreement.
 
  The Adviser's activities are subject to the review and supervision of the
Board of Trustees of the Trust, of which the fund is a series, to whom the
Adviser renders periodic reports of the Fund's investment activities.
 
  The investment advisory agreement for the Fund will continue in effect from
year to year if specifically approved by the trustees of the Trust, of which the
Fund is a separate series (or by the Fund's shareholders), and by the
disinterested trustees in compliance with the requirements of the 1940 Act. The
agreement may be terminated without penalty upon 60 days' written notice by
either party thereto and will automatically terminate in the event of
assignment.
 
  The investment advisory agreement specifies that the Adviser will reimburse
the Fund for annual expenses of the Fund which exceed the most stringent limit
prescribed by any State in which the Fund's shares are offered for sale.
Currently, the most stringent limit in any State would require such
reimbursement to the extent that aggregate operating expenses of the Fund
(excluding interest, taxes and other expenses which may be excludable under
applicable state law) exceed in any fiscal year 2 1/2% of the average annual net
assets of the Fund up to $30 million, 2% of the average annual net assets of the
Fund of the next $70 million and 1 1/2% of the remaining average annual net
assets of the Fund. In addition to making any required reimbursements, the
Adviser may in its discretion, but is not obligated to, waive all or any portion
of its fee or assume all or any portion of the expenses of any of the Fund.
 
   
  For the years ended December 31, 1996, 1995 and 1994, the Fund paid advisory
expenses of $3,953,376, $3,705,007 and $3,519,429, respectively.
    
 
OTHER AGREEMENTS
 
   
  ACCOUNTING SERVICES AGREEMENT.  The Fund has entered into an accounting
services agreement pursuant to which the Adviser provides accounting services
supplementary to those provided by the Custodian. Such services are expected to
enable the Fund to more closely monitor and maintain its accounts and records.
The Fund shares with the other Van Kampen American Capital mutual funds in the
cost of providing such services, with 25% of such costs shared proportionately
based on the respective number of classes of securities issued per fund and the
remaining 75% of such cost based proportionally on their respective net assets.
    
 
   
  For the years ended December 31, 1996, 1995 and 1994, the Fund paid expenses
of approximately $39,200, $33,600 and $18,300, respectively, representing the
Adviser's cost of providing accounting services.
    
 
   
  LEGAL SERVICES AGREEMENT. The Fund and each of the other Van Kampen American
Capital funds advised by the Adviser and distributed by the Distributor have
entered into Legal Services Agreements pursuant to which Van Kampen American
Capital provides legal services, including without limitation: accurate
maintenance of the fund's minute books and records, preparation and oversight of
the fund's regulatory reports, and other information provided to shareholders,
as well as responding to day-to-day legal issues on behalf of the funds. Payment
by the Fund for such services is made on a cost basis for the salary and salary
related benefits, including but not limited to bonuses, group insurances and
other regular wages for the employment of personnel, as well as overhead and the
expenses related to the office space and the equipment necessary to render the
legal services. Other funds distributed by the Distributor also receive legal
services from Van Kampen American Capital. Of the total costs for legal services
provided to funds distributed by the Distributor, one half of such costs are
allocated equally to each fund and the remaining one half of such costs are
allocated to specific funds based on monthly time records.
    
 
                                      B-21
<PAGE>   433
 
   
  For the years ended December 31, 1996, 1995 and 1994, the Fund paid expenses
of approximately $27,100, $40,000 and $40,000, respectively, representing Van
Kampen American Capital's cost of providing legal services.
    
 
   
                     CUSTODIAN AND INDEPENDENT ACCOUNTANTS
    
 
  State Street Bank and Trust Company, 225 Franklin Street, P.O. Box 1713,
Boston, MA 02105-1713, is the custodian of the Fund and has custody of all
securities and cash of the Fund. The custodian, among other things, attends to
the collection of principal and income, and payment for and collection of
proceeds of securities bought and sold by the Fund.
 
   
  The independent accountants for the Fund are KPMG Peat Marwick LLP, Chicago,
Illinois. The selection of independent accountants will be subject to
ratification by the shareholders of the Fund at any annual meeting of
shareholders.
    
 
                PORTFOLIO TRANSACTIONS AND BROKERAGE ALLOCATION
 
  The Adviser will place orders for portfolio transactions for the Fund with
broker-dealer firms giving consideration to the quality, quantity and nature of
each firms' professional services. These services include execution, clearance
procedures, wire service quotations and statistical and other research
information provided to the Fund and the investment adviser, including
quotations necessary to determine the value of the Fund's net assets. Any
research benefits derived are available for all clients of the investment
adviser. Since statistical and other research information is only supplementary
to the research efforts of the Adviser and still must be analyzed and reviewed
by its staff, the receipt of research information is not expected to materially
reduce its expenses.
 
  If it is believed to be in the best interests of the Fund, the Adviser may
place portfolio transactions with brokers who provide the types of research
service described above, even if it means the Fund will have to pay a higher
commission (or, if the broker's profit is part of the cost of the security, will
have to pay a higher price for the security) than would be the case if no weight
were given to the broker's furnishing of those research services. This will be
done, however, only if, in the opinion of the Adviser, the amount of additional
commission or increased cost is reasonable in relation to the value of such
services.
 
  In selecting among the firms believed to meet the criteria for handling a
particular transaction, the Adviser may take into consideration that certain
firms (i) provide market, statistical or other research information to the Fund
and the Adviser, (ii) have sold or are selling shares of the Fund and (iii) may
select firms that are affiliated with the Fund, its investment adviser or its
distributor and other principal underwriters.
 
  If purchases or sales of securities of the Fund and of one or more other
investment companies or clients advised by the Adviser are considered at or
about the same time, transactions in such securities will be allocated among the
several investment companies and clients in a manner deemed equitable to all by
the Adviser, taking into account the respective sizes of the funds and the
amount of securities to be purchased or sold. Although it is possible that in
some cases this procedure could have a detrimental effect on the price or volume
of the security as far as the Fund is concerned, it is also possible that the
ability to participate in volume transactions and to negotiate lower brokerage
commissions will be beneficial to the Fund.
 
  While the Adviser will be primarily responsible for the placement of the
Fund's business, the policies and practices in this regard must be consistent
with the foregoing and will at all times be subject to review by the Trustees of
the Trust, of which the Fund is a separate series.
 
  The Trustees have adopted certain policies incorporating the standards of Rule
17e-1 issued by the SEC under the 1940 Act which requires that the commission
paid to the Distributor and other affiliates of the Fund must be reasonable and
fair compared to the commissions, fees or other remuneration received or to be
received by other brokers in connection with comparable transactions involving
similar securities during a comparable period of time. The rule and procedures
also contain review requirements and require the Adviser to furnish reports to
the Trustees and to maintain records in connection with such reviews. After
consideration
 
                                      B-22
<PAGE>   434
 
of all factors deemed relevant, the Trustees will consider from time to time
whether the advisory fee will be reduced by all or a portion of the brokerage
commission given to brokers that are affiliated with the Fund.
 
  State securities laws may differ from the interpretations of federal law
expressed herein, and banks and financial institutions may be required to
register as dealers pursuant to state law.
 
                             TAX STATUS OF THE FUND
 
   
  The Trust and any of its series, including the Fund, will be treated as
separate corporations for federal income tax purposes. The Fund intends to
qualify each year and to elect to be treated as a regulated investment company
under the Code. If the Fund so qualifies and distributes each year to its
shareholders at least 90% of its net investment income (including tax-exempt
interest, taxable income and net short-term capital gain, but not net capital
gains, which are the excess of long-term capital gains over net short-term
capital losses) in each year, it will not be required to pay federal income
taxes on any income distributed to shareholders. The Fund intends to distribute
at least the minimum amount of net investment income necessary to satisfy the
90% distribution requirement. The Fund will not be subject to federal income tax
on any net capital gains distributed to shareholders.
    
 
                                THE DISTRIBUTOR
 
   
  The Distributor offers one of the industry's broadest lines of investments --
encompassing mutual funds, closed-end funds and unit investment trusts -- and is
currently the nation's 5th largest broker-sold mutual fund group according to
Strategic Insight, July 1995. VKAC manages or supervises more than $57 billion
in mutual funds, closed-end funds and unit investment trusts -- assets which
have been entrusted to VKAC in more than 2 million investor accounts. VKAC has
one of the largest research teams (outside of the rating agencies) in the
country, with more than 80 analysts devoted to various specializations. Each of
our high yield analysts, based either in San Francisco, Chicago, Houston or
Boston, has the responsibility to cover a specific region of the country. This
regional focus enables each high yield analyst to provide more specialized
coverage of the market and alert the portfolio manager to issues of local
importance.
    
 
   
  Shares of the Fund are offered on a continuous basis through the Distributor.
The Distributor is a wholly-owned subsidiary of Van Kampen American Capital,
which is a subsidiary of VK/AC Holding, Inc. VK/AC Holding, Inc. is a
wholly-owned subsidiary of MSAM Holdings II, Inc. which, in turn, is a
wholly-owned subsidiary of Morgan Stanley Group Inc. The principal office of the
Fund, the Adviser, the Distributor and VKAC is located at One Parkview Plaza,
Oakbrook Terrace, Illinois 60181.
    
 
   
  Morgan Stanley Group Inc. and various of its directly or indirectly owned
subsidiaries, including Morgan Stanley & Co. Incorporated, a registered
broker-dealer and investment adviser, and Morgan Stanley International, are
engaged in a wide range of financial services. Their principal businesses
include securities underwriting, distribution and trading; merger, acquisition,
restructuring and other corporate finance advisory activities; merchant banking;
stock brokerage and research services; asset management; trading of futures,
options, foreign exchange, commodities and swaps (involving foreign exchange,
commodities, indices and interest rates); real estate advice, financing and
investing; and global custody, securities clearance services and securities
lending.
    
 
   
  On February 5, 1997, Morgan Stanley Group Inc. and Dean Witter, Discover & Co.
announced that they had entered into an Agreement and Plan of Merger to form
Morgan Stanley, Dean Witter, Discover & Co. Subject to certain conditions being
met, it is currently anticipated that the transaction will close in mid-1997.
Thereafter, Van Kampen American Capital Asset Management, Inc. will be an
indirect subsidiary of Morgan Stanley, Dean Witter, Discover & Co.
    
 
   
  Dean Witter, Discover & Co. is a financial services company with three major
businesses; full service brokerage, credit services and asset management.
    
 
   
  Pursuant to a distribution agreement, the Distributor will purchase shares of
the Fund for resale to the public, either directly or through securities
dealers, and is obligated to purchase only those shares for which it
    
 
                                      B-23
<PAGE>   435
 
has received purchase orders. A discussion of how to purchase and redeem the
Fund's shares and how the Fund's shares are priced is contained in the
Prospectus.
 
   
                         DISTRIBUTION AND SERVICE PLANS
    
 
   
  The Fund has adopted a distribution plan (the "Distribution Plan") with
respect to each class of its shares pursuant to Rule 12b-1 under the 1940 Act.
The Fund also has adopted a service plan (the "Service Plan") with respect to
each class of its shares. The Distribution Plan and the Service Plan sometimes
are referred to herein as the "Plans". The Plans provide that the Fund may spend
a portion of the Fund's average daily net assets attributable to each class of
shares in connection with distribution of the respective class of shares and in
connection with the provision of ongoing services to shareholders of such class,
respectively. The Distribution Plan and the Service Plan are being implemented
through an agreement (the "Distribution and Service Agreement") with the
Distributor of each class of the Fund's shares, sub-agreements between the
Distributor and members of the NASD who are acting as securities dealers and
NASD members or eligible non-members who are acting as brokers or agents and
similar agreements between the Fund and financial intermediaries who are acting
as brokers (collectively, "Selling Agreements") that may provide for their
customers or clients certain services or assistance, which may include, but not
be limited to, processing purchase and redemption transactions, establishing and
maintaining shareholder accounts regarding the Fund, and such other services as
may be agreed to from time to time and as may be permitted by applicable
statute, rule or regulation. Brokers, dealers and financial intermediaries that
have entered into sub-agreements with the Distributor and sell shares of the
Fund are referred to herein as "financial intermediaries."
    
 
   
  Under the Distribution and Service Agreement and the Selling Agreements,
financial intermediaries that sold shares prior to July 1, 1987, or prior to the
beginning of the calendar quarter in which the Selling Agreement between the
Fund and such financial intermediary was approved by the Fund's Board of
Trustees (an "Implementation Date") are not eligible to receive compensation
pursuant to such Distribution and Service Agreement or Selling Agreement. To the
extent that there remain outstanding shares of the Fund that were purchased
prior to all Implementation Dates, the percentage of the total average daily net
asset value of a class of shares that may be utilized pursuant to the
Distribution and Service Agreement will be less than the maximum percentage

  The Distributor must submit quarterly reports to the Board of Trustees of the
Trust, of which the Fund is a series, setting forth separately by class of
shares all amounts paid under the Distribution Plan and the purposes for which
such expenditures were made, together with such other information as from time
to time is reasonably requested by the Trustees. The Plans provide that they
will continue in full force and effect from year to year so long as such
continuance is specifically approved by a vote of the Trustees, and also by a
vote of the disinterested Trustees, cast in person at a meeting called for the
purpose of voting on the Plans. Each of the Plans may not be amended to increase
materially the amount to be spent for the services described therein with
respect to either class of shares without approval by a vote of a majority of
the outstanding voting shares of such class, and all material amendments to
either of the Plans must be approved by the Trustees and also by the
disinterested Trustees. Each of the Plans may be terminated with respect to
either class of shares at any time by a vote of a majority of the disinterested
Trustees or by a vote of a majority of the outstanding voting shares of such
class.

CLASS A SHARES
 
  From time to time marketing materials may provide a portfolio manager update,
an adviser update or discuss general economic conditions and outlooks. The
Fund's marketing materials may also show the Fund's asset class diversification,
top five sectors, ten largest holdings and other Fund asset structures, such as
duration, maturity, coupon, NAV, rating breakdown, AMT exposure and number of
issues in the portfolio. Materials may also mention how Van Kampen American
Capital believes the Fund compares relative to other Van Kampen American Capital
funds. Materials may also discuss the Dalbar Financial Services study from 1984
to 1994 which studied investor cash flow into and out of all types of mutual
funds. The ten year study found that investors who bought mutual fund shares and
held such shares outperformed investors who bought and sold. The Dalbar study
conclusions were consistent regardless of if shareholders purchased their funds
in direct or sales force distribution channels. The study showed that investors
working with a professional representative have tended over time to earn higher
returns than those who invested directly. The Fund will also be marketed on the
Internet.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
The Board of Trustees and Shareholders of
Van Kampen American Capital Tax Free High Income Fund:
 
We have audited the accompanying statement of assets and liabilities of Van
Kampen American Capital Tax Free High Income Fund (the "Fund"), including the
portfolio of investments, as of December 31, 1996, and the related statement of
operations for the year then ended, the statement of changes in net assets for
each of the two years in the period then ended, and the financial highlights for
each of the periods presented. These financial statements and financial
highlights are the responsibility of the Fund's management. Our responsibility
is to express an opinion on these financial statements and financial highlights
based on our audits.
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of
December 31, 1996, by correspondence with the custodian and brokers. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.
    In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of Van
Kampen American Capital Tax Free High Income Fund as of December 31, 1996, the
results of its operations for the year then ended, the changes in its net assets
for each of the two years in the period then ended, and the financial highlights
for each of the periods presented, in conformity with generally accepted
accounting principles.

1. SIGNIFICANT ACCOUNTING POLICIES
 
Van Kampen American Capital Tax Free High Income Fund (the "Fund") is organized
as a series of the Van Kampen American Capital Tax Free Trust, a Delaware
business trust, and is registered as a diversified open-end management
investment company under the Investment Company Act of 1940, as amended. The
Fund's investment objective is to provide investors with a high level of current
income exempt from federal income taxes primarily through investment in a
diversified portfolio of medium and lower grade municipal securities. The Fund
commenced investment operations on June 28, 1985. The distribution of the Fund's
Class B and Class C shares commenced on May 1, 1993 and August 13, 1993,
respectively.
 
       The following is a summary of significant accounting policies
consistently followed by the Fund in the preparation of its financial
statements. The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
A. SECURITY VALUATION--Investments are stated at value using market quotations
or, if such valuations are not available, estimates obtained from yield data
relating to instruments or securities with similar characteristics in accordance
with procedures established in good faith by the Board of Trustees. Investments
valued using estimates of market value are generally those non-rated securities
in which the Fund owns over 90% of the original bond issue. At December 31,
1996, 18% of the Fund's net assets consisted of such securities. Short-term
securities with remaining maturities of 60 days or less are valued at amortized
cost.
 
B. SECURITY TRANSACTIONS--Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis. The
Fund may purchase and sell securities on a "when issued" or "delayed delivery"
basis, with settlement to occur at a later date. The value of the security so
purchased is subject to market fluctuations during this period. The Fund will
maintain, in a segregated account with its custodian, assets having an aggregate
value at least equal to the amount of the when issued or delayed delivery
purchase commitments until payment is made.
 
C. INVESTMENT INCOME--Interest income is recorded on an accrual basis. Bond
premium and original issue discount are amortized over the expected life of each
applicable security.
 
D. FEDERAL INCOME TAXES--It is the Fund's policy to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no provision for federal income taxes is required.
 
       The Fund intends to utilize provisions of the federal income tax laws
which allow it to carry a realized capital loss forward for eight years
following the year of the loss and offset such losses against any future
realized capital gains. At December 31, 1996, the Fund had an accumulated
capital loss carryforward for tax purposes of $82,799,196 which expires between
December 31, 1999 and December 31, 2004. Net realized gains or losses may differ
for financial reporting and tax purposes primarily as a result of the deferral
of post October 31 losses, gains or losses recognized for tax purposes on open
futures positions and the capitalization of reorganization and restructuring
costs for tax purposes.

- --------------------------------------------------------------------------------
 
E. DISTRIBUTION OF INCOME AND GAINS--The Fund declares daily and pays monthly
dividends from net investment income. Net realized gains, if any, are
distributed annually.
 
       For the year ended December 31, 1996, 99.1% of the income distributions
made by the Fund were exempt from federal income taxes.
 
       Due to inherent differences in the recognition of interest income under
generally accepted accounting principles and federal income tax purposes, for
those securities which the Fund has placed on non-accrual status, the amount of
distributable net investment income may differ between book and federal income
tax purposes for a particular period. These differences are temporary in nature,
but may result in book basis distributions in excess of net investment income
for certain periods. Permanent book and tax basis differences relating to the
recognition of certain expenses which are not deductible for tax purposes
totaling $167,225 were reclassified from accumulated distributions in excess of
net investment income to capital.
 
2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES
Under the terms of the Fund's Investment Advisory Agreement, Van Kampen American
Capital Investment Advisory Corp. (the "Adviser") will provide investment advice
and facilities to the Fund for an annual fee payable monthly as follows:

</TABLE>
 
       For the year ended December 31, 1996, the Fund recognized expenses of
approximately $54,600 representing legal services provided by Skadden, Arps,
Slate, Meagher & Flom (Illinois), counsel to the Fund, of which a trustee of the
Fund is an affiliated person.
 
       For the year ended December 31, 1996, the Fund recognized expenses of
approximately $66,300 representing Van Kampen American Capital Distributors,
Inc.'s or its affiliates' (collectively "VKAC") cost of providing accounting,
cash management and legal services to the Fund.
 
       ACCESS Investor Services, Inc. ("ACCESS"), an affiliate of the Adviser,
serves as the shareholder servicing agent of the Fund. For the year ended
December 31, 1996, the Fund recognized expenses of approximately $673,900,
representing ACCESS' cost of providing transfer agency and shareholder services
plus a profit.
 
       Additionally, for the year ended December 31, 1996, the Fund reimbursed
VKAC approximately $161,200 related to the cost of consolidating the VKAC
open-end fund complex. Payment was contingent upon the realization by the Fund
of cost efficiencies in certain expense categories resulting from the
consolidation.
 
       Certain officers and trustees of the Fund are also officers and directors
of VKAC. The Fund does not compensate its officers or trustees who are officers
of VKAC. For the year ended December 31, 1996, the Adviser reimbursed the Fund
for certain trustees' compensation in connection with the July 1995 increase in
the number of trustees of the Fund.
 
       The Fund has implemented deferred compensation and retirement plans for
its trustees. Under the deferred compensation plan, trustees may elect to defer
all or a portion of their compensation to a later date. The retirement plan
covers those trustees who are not officers of VKAC.

4. INVESTMENT TRANSACTIONS
During the period, the cost of purchases and proceeds from sales of investments,
excluding short-term investments, were $518,452,919 and $475,606,658,
respectively.
 
5. DERIVATIVE FINANCIAL INSTRUMENTS
A derivative financial instrument in very general terms refers to a security
whose value is "derived" from the value of an underlying asset, reference rate
or index.
 
       The Fund has a variety of reasons to use derivative instruments, such as
to attempt to protect the Fund against possible changes in the market value of
its portfolio and to manage the portfolio's effective yield, maturity and
duration. All of the Fund's portfolio holdings, including derivative
instruments, are marked to market each day with the change in value reflected in
the unrealized appreciation/depreciation on investments. Upon disposition, a
realized gain or loss is recognized accordingly, except when exercising an
option contract or taking delivery of a security underlying a futures contract.
In these instances, the recognition of gain or loss is postponed until the
disposal of the security underlying the option or futures contract.
 
       Summarized below are the specific types of derivative financial
instruments used by the Fund.
 
A. OPTION CONTRACTS--An option contract gives the buyer the right, but not the
obligation to buy (call) or sell (put) an underlying item at a fixed exercise
price during a specified period. These contracts are generally used by the Fund
to manage the portfolio's effective maturity and duration.
 
       Transactions in options for the year ended December 31, 1996, were as
follows:

</TABLE>
 
B. FUTURES CONTRACTS--A futures contract is an agreement involving the delivery
of a particular asset on a specified future date at an agreed upon price. The
Fund generally invests in futures on U.S. Treasury Bonds and the Municipal Bond
Index and typically closes the contract prior to the delivery date. These
contracts are generally used to manage the portfolio's effective maturity and
duration.
 
       Upon entering into futures contracts, the Fund maintains, in a segregated
account with its custodian, securities with a value equal to its obligation
under the futures contracts. During the period the futures contract is open,
payments are received from or made to the broker based upon changes in the value
of the contract (the variation margin).

</TABLE>
 
C. INDEXED SECURITIES--These instruments are identified in the portfolio of
investments. The price of these securities may be more volatile than the price
of a comparable fixed rate security.
 
       An Inverse Floating security is one where the coupon is inversely indexed
to a short-term floating interest rate multiplied by a specified factor. As the
floating rate rises, the coupon is reduced. Conversely, as the floating rate
declines, the coupon is increased. These instruments are typically used by the
Fund to enhance the yield of the portfolio.
 
       An Embedded Swap security includes a swap component such that the fixed
coupon component of the underlying bond is adjusted by the difference between
the security's fixed swap rate and the floating swap index. These instruments
are typically used by the Fund to enhance the yield of the portfolio.
 
6. DISTRIBUTION AND SERVICE PLANS
The Fund and its shareholders have adopted a distribution plan pursuant to Rule
12b-1 under the Investment Company Act of 1940 and a service plan (collectively
the "Plans"). The Plans govern payments for the distribution of the Fund's
shares, ongoing shareholder services and maintenance of shareholder accounts.
 
       Annual fees under the Plans of up to .25% for Class A net assets and
1.00% each for Class B and Class C net assets are accrued daily. Included in
these fees for the year ended December 31, 1996 are payments to VKAC of
approximately $1,163,200.

                             THE FUND AND THE TRUST
 
   
  Van Kampen American Capital Insured Tax Free Income Fund (the "Fund") is a
separate diversified series of the Trust is an unincorporated business trust
established under the laws of the State of Delaware by an Agreement and
Declaration of Trust dated as of May 10, 1995, (the "Declaration of Trust"). The
Declaration of Trust permits the Trustees to create one or more separate
investment portfolios and issue a series of shares for each portfolio. The
Trustees can further sub-divide each series of shares into one or more classes
of shares for each portfolio. At present, the Fund, Van Kampen American Capital
Tax Free High Income Fund, Van Kampen American Capital California Insured Tax
Free Fund, Van Kampen American Capital Municipal Income Fund, Van Kampen
American Capital Intermediate Term Municipal Income Fund, Van Kampen American
Capital Florida Insured Tax Free Income Fund, Van Kampen American Capital New
Jersey Tax Free Income Fund and Van Kampen American Capital New York Tax Free
Income Fund have been organized as series of the Trust and have commenced
investment operations. Van Kampen American Capital California Tax Free Income
Fund, Van Kampen American Capital Michigan Tax Free Income Fund, Van Kampen
American Capital Missouri Tax Free Income Fund and Van Kampen American Capital
Ohio Tax Free Income Fund have been organized as series of the Trust but have
not commenced investment operations. Other series may be organized and offered
in the future. The Fund was originally organized as a Maryland corporation under
the name Van Kampen Merritt Insured Tax Free Fund Inc., was subsequently
reorganized into a sub-trust of Van Kampen Merritt Tax Free Fund, a
Massachusetts business trust, under the name Van Kampen Merritt Insured Tax Free
Income Fund as of February 22, 1988. The Fund was again reorganized as a series
of the Trust and adopted its present name as of July 31, 1995.
    
 
  Each share in a series of the Trust represents an equal proportionate interest
in the assets of such series with each other share in such series and no
interest in any other series. No series is subject to the liabilities of any
other series. The Declaration of Trust provides that shareholders are not liable
for any liabilities of the Trust or any of its series, requires inclusion of a
clause to that effect in every agreement entered into by the Trust or any of its
series and indemnifies shareholders against any such liability.
 
  Shares of the Trust entitle their holders to one vote per share; however,
separate votes are taken by each series on matters affecting an individual
series. For example, a change in investment policy for a series would be voted
upon by shareholders of only the series involved. Except as described in the
Prospectus, shares do not have cumulative voting rights, preemptive rights or
any conversion or exchange rights other than those described in the Prospectus.
The Trust does not contemplate holding regular meetings of shareholders to elect
Trustees or otherwise. However, the holders of 10% or more of the outstanding
shares may by written request require a meeting to consider the removal of
Trustees by a vote of two-thirds of the shares then outstanding cast in person
or by proxy at such meeting.
 
  The Trustees may amend the Declaration of Trust (including with respect to any
series) in any manner without shareholder approval, except that the Trustees may
not adopt any amendment adversely affecting the rights of shareholders of any
series without approval by a majority of the outstanding shares of each affected
series entitled to vote (or such higher vote as may be required by the
Investment Company Act of 1940, as amended (the "1940 Act"), or other applicable
law).
 
  Statements contained in this Statement of Additional Information to the
contents of any contract or other document referred to are not necessarily
complete, and, in each instance, reference is made to the copy of such contract
or other document filed as an exhibit to the Registration Statement of which
this Statement of Additional Information forms a part, each such statement being

                      INVESTMENT POLICIES AND RESTRICTIONS
 
  The investment objective of the Fund is set forth in the Prospectus under the
caption "Investment Objectives and Policies." There can be no assurance that the
Fund will achieve its objective.
 
  Fundamental investment restrictions limiting the investments of the Fund
provide that the Fund may not:
 
   
   1. Purchase any securities (other than tax exempt obligations guaranteed by
      the United States Government or by its agencies or instrumentalities), if
      as a result more than 5% of the Fund's total assets (taken at current
      value) would then be invested in securities of a single issuer or if as a
      result the Fund would hold more than 10% of the outstanding voting
      securities of any single issuer, except that the Fund
    
 
                                       B-2
<PAGE>   459
 
   
      may purchase securities of other investment companies to the extent
      permitted by (i) the 1940 Act, as amended from time to time, (ii) the
      rules and regulations promulgated by the SEC under the 1940 Act, as
      amended from time to time, or (iii) an exemption or other relief from the
      provisions of the 1940 Act.
    
 
   
   2. Invest more than 25% of its assets in a single industry. (As described in
      the Prospectus, the Fund may from time to time invest more than 25% of its
      assets in a particular segment of the municipal bond market; however, the
      Fund will not invest more than 25% of its assets in industrial development
      bonds in a single industry), except that the Fund may purchase securities
      of other investment companies to the extent permitted by (i) the 1940 Act,
      as amended from time to time, (ii) the rules and regulations promulgated
      by the SEC under the 1940 Act, as amended from time to time, or (iii) an
      exemption or other relief from the provisions of the 1940 Act.
    
 
   3. Borrow money, except from banks for temporary purposes and then in amounts
      not in excess of 5% of the total asset value of the Fund, or mortgage,
      pledge or hypothecate any assets except in connection with a borrowing and
      in amounts not in excess of 10% of the total asset value of the Fund.
      Borrowings may not be made for investment leverage, but only to enable the
      Fund to satisfy redemption requests where liquidation of portfolio
      securities is considered disadvantageous or inconvenient. In this
      connection, the Fund will not purchase portfolio securities during any
      period that such borrowings exceed 5% of the total asset value of the
      Fund. Notwithstanding this investment restriction, the Fund may enter into
      "when issued" and "delayed delivery" transactions as described in the
      Prospectus.
 
   4. Make loans, except to the extent the tax exempt obligations the Fund may
      invest in are considered to be loans.
 
   5. Buy any securities "on margin." The deposit of initial or maintained
      margin in connection with interest rate or other financial futures or
      index contracts or related options is not considered the purchase of a
      security on margin.
 
   6. Sell any securities "short," write, purchase or sell puts, calls or
      combinations thereof, or purchase or sell interest rate or other financial
      futures or index contracts or related options, except as hedging
      transactions in accordance with the requirements of the Securities and
      Exchange Commission and the Commodity Futures Trading Commission.
 
   7. Act as an underwriter of securities, except to the extent the Fund may be
      deemed to be an underwriter in connection with the sale of securities held
      in its portfolio.
 
   
   8. Make investments for the purpose of exercising control or participation in
      management, except that the Fund may purchase securities of other
      investment companies to the extent permitted by (i) the 1940 Act, as
      amended from time to time, (ii) the rules and regulations promulgated by
      the SEC under the 1940 Act, as amended from time to time, or (iii) an
      exemption or other relief from the provisions of the 1940 Act.
    
 
   
   9. Invest in securities issued by other investment companies except as part
      of a merger, reorganization or other acquisition and extent permitted by
      (i) the 1940 Act, as amended from time to time, (ii) the rules and
      regulations promulgated by the SEC under the 1940 Act, as amended from
      time to time, or (iii) an exemption or other relief from the provisions of
      the 1940 Act.
    
 
  10. Invest in equity interests in oil, gas or other mineral exploration of
      development programs.
 
  11. Purchase or sell real estate, commodities or commodity contracts, except
      as set forth in item 6 above and except to the extent the municipal
      securities the Fund may invest in are considered to be interests in real
      estate.
 
  The Fund may not change any of these investment restrictions nor any other
fundamental policy as they apply to the Fund without the approval of the lesser
of (i) more than 50% of the Fund's outstanding shares or (ii) 67% of the Fund's
shares present at a meeting at which the holders of more than 50% of the
outstanding shares are present in person or by proxy. As long as the percentage
restrictions described above are satisfied at the time of the investment or
borrowing, the Fund will be considered to have abided by those restrictions even
if, at a later time, a change in values or net assets causes an increase or
decrease in percentage beyond that allowed.
 
                                       B-3
<PAGE>   460
 
  The Fund generally will not engage in the trading of securities for the
purpose of realizing short-term profits, but it will adjust its portfolio as
deemed advisable in view of prevailing or anticipated market conditions to
accomplish the Fund's investment objectives. For example, the Fund may sell
portfolio securities in anticipation of a movement in interest rates. Frequency
of portfolio turnover will not be a limiting factor if the Fund considers it
advantageous to purchase or sell securities. Portfolio turnover is calculated by
dividing the lesser of purchases or sales of portfolio securities by the monthly
average value of the securities in the portfolio during the year. Securities,
including options, whose maturity or expiration date at the time of acquisition
were one year or less are excluded from such calculation. The Fund anticipates
that its annual portfolio turnover rate will normally be less than 100%.
 
  The Fund does not intend to invest in certain "private activity" obligations
issued after August 7, 1986. Interest on such "private activity" obligations is
treated as a preference item for the purpose of calculating the alternative
minimum tax. If the Fund were to invest in such "private activity" obligations,
dividends paid to an investor who is subject to the alternative minimum tax
might not be completely tax exempt or might cause an investor to be subject to
such tax.
 
                      ADDITIONAL INVESTMENT CONSIDERATIONS
 
  MUNICIPAL SECURITIES.  Municipal securities include long-term obligations,
which are often called municipal bonds, as well as shorter term municipal notes,
municipal leases, and tax-exempt commercial paper. Under normal market
conditions, longer term municipal securities generally provide a higher yield
than shorter term municipal securities, and therefore the Fund generally expects
to be invested primarily in longer term municipal securities. The Fund will,
however, invest in shorter term municipal securities when yields are greater
than yields available on longer term municipal securities, for temporary
defensive purposes and when redemption requests are expected. The two principal
classifications of municipal bonds are "general obligation" and "revenue" or
"special obligation" bonds, which include "industrial revenue bonds." General
obligation bonds are secured by the issuer's pledge of its faith, credit, and
taxing power for the payment of principal and interest. Revenue or special
obligation bonds are payable only from the revenues derived from a particular
facility or class of facilities or, in some cases, from the proceeds of a
special tax or other specific revenue source such as from the user of the
facility being financed.
 
  Also included within the general category of municipal securities are
participations in lease obligations or installment purchase contract obligations
(hereinafter collectively called "lease obligations") of municipal authorities
or entities used to finance the acquisition of equipment and facilities.
Although lease obligations do not constitute general obligations of the
municipality for which the municipality's taxing power is pledged, a lease
obligation is ordinarily backed by the municipality's covenant to budget for,
appropriate and make the payments due under the lease obligation. However,
certain lease obligations contain "non-appropriation" clauses which provide that
the municipality has no obligation to make lease or installment purchase
payments in future years unless money is appropriated for such purpose on a
yearly basis. In addition to the "non-appropriation" risk, these securities
represent a relatively new type of financing that has not yet developed the
depth of marketability associated with more conventional bonds. Although
"non-appropriation" lease obligations are often secured by the underlying
property, disposition of the property in the event of foreclosure might prove
difficult. There is no limitation on the percentage of the Fund's assets that
may be invested in "non-appropriation" lease obligations. In evaluating such
lease obligations, the Adviser will consider such factors as it deems
appropriate, which factors may include (a) whether the lease can be cancelled,
(b) the ability of the lease obligee to direct the sale of the underlying
assets, (c) the general creditworthiness of the lease obligor, (d) the
likelihood that the municipality will discontinue appropriating funding for the
leased property in the event such property is no longer considered essential by
the municipality, (e) the legal recourse of the lease obligee in the event of
such a failure to appropriate funding and (f) any limitations which are imposed
on the lease obligor's ability to utilize substitute property or services than
those covered by the lease obligation.
 
  Also included within the term Municipal Securities are participation
certificates issued by state and local governments or authorities to finance the
acquisition of equipment and facilities. They may represent
 
                                       B-4
<PAGE>   461
 
participations in a lease, an installment purchase contract, or a conditional
sales contract. Some municipal leases and participation certificates may not be
readily marketable.
 
  The "issuer" of municipal securities generally is deemed to be the
governmental agency, authority, instrumentality or other political subdivision,
or the non-governmental user of a revenue bond-financed facility, the assets and
revenues of which will be used to meet the payment obligations, or the guarantee
of such payment obligations, of the municipal securities.
 
  The Fund may purchase floating and variable rate demand notes, which are
municipal securities normally having a stated maturity in excess of one year,
but which permit the holder to demand payment of principal at any time, or at
specified intervals. The issuer of such notes normally has a corresponding
right, after a given period, to prepay at its discretion upon notice to the
noteholders the outstanding principal amount of the notes plus accrued interest.
The interest rate on a floating rate demand note is based on a known lending
rate, such as a bank's prime rate, and is adjusted automatically each time such
rate is adjusted. The interest rate on a variable rate demand note is adjusted
automatically at specified intervals.
 
  The Fund also may invest up to 15% of its total assets in derivative variable
rate municipal securities such as inverse floaters whose rates vary inversely
with changes in market rates of interest. Such derivative variable rate
municipal securities may pay a rate of interest determined by applying a
multiple to the variable rate. The extent of increases and decreases in the
value of derivative municipal securities whose rates vary inversely with changes
in market rates of interest in response to such changes in market rates
generally will be larger than comparable changes in the value of an equal
principal amount of a fixed rate municipal security having similar credit
quality, redemption provisions and maturity. In addition, the Fund may invest in
derivative municipal securities the terms of which include elements of, or are
similar in effect to, certain Strategic Transactions in which the Fund may
engage. Such municipal securities may by their terms, for example, have economic
characteristics comparable to, among other things, a swap, cap, floor or collar
transaction with respect to such security for a period of time prior to its
stated maturity. See "Additional Investment Considerations -- Strategic
Transactions" in this Statement of Additional Information.
 
  The Fund may also acquire custodial receipts or certificates underwritten by
securities dealers or banks that evidence ownership of future interest payments,
principal payments or both on certain municipal securities. The underwriter of
these certificates or receipts typically purchases municipal securities and
deposits the securities in an irrevocable trust or custodial account with a
custodian bank, which then issues receipts or certificates that evidence
ownership of the periodic unmatured coupon payments and the final principal
payment on the obligations. Although under the terms of a custodial receipt, the
Fund typically would be authorized to assert its rights directly against the
issuer of the underlying obligation, the Fund could be required to assert
through the custodian bank those rights as may exist against the underlying
issuer. Thus, in the event the underlying issuer fails to pay principal and/or
interest when due, the Fund may be subject to delays, expenses and risks that
are greater than those that would have been involved if the Fund had purchased a
direct obligation of the issuer. In addition, in the event that the trust or
custodial account in which the underlying security has been deposited is
determined to be an association taxable as a corporation, instead of a
non-taxable entity, the yield on the underlying security would be reduced in
recognition of any taxes paid.
 
  Although the municipal securities in which the Fund may invest will be insured
as to timely payment of both principal and interest, municipal securities, like
other debt obligations, are subject to the risk of non-payment. The ability of
issuers of municipal securities to make timely payments of interest and
principal may be adversely impacted in general economic downturns and as
relative governmental cost burdens are allocated and reallocated among federal,
state and local governmental units. Such non-payment would result in a reduction
of income to the Fund, and could result in a reduction in the value of the
municipal security experiencing non-payment and a potential decrease in the net
asset value of the Fund. Issuers of municipal securities might seek protection
under the bankruptcy laws. In the event of bankruptcy of such an issuer, the
Fund could experience delays and limitations with respect to the collection of
principal and interest on such municipal securities and the Fund may not, in all
circumstances, be able to collect all principal and interest to which it is
entitled. To enforce its rights in the event of a default in the payment of
interest or repayment of principal, or both, the Fund may take possession of and
manage the assets securing the issuer's obligations on such securities, which
may increase the Fund's operating expenses and adversely affect the net asset
value of
 
                                       B-5
<PAGE>   462
 
the Fund. Any income derived from the Fund's ownership or operation of such
assets may not be tax-exempt. In addition, the Fund's intention to qualify as a
"regulated investment company" under the Internal Revenue Code of 1986, as
amended (the "Code"), may limit the extent to which the Fund may exercise its
rights by taking possession of such assets, because as a regulated investment
company the Fund is subject to certain limitations on its investments and on the
nature of its income.
 
  INVESTMENT PRACTICES.  If the Adviser deems it appropriate to seek to hedge
the Fund's portfolio against market value changes, the Fund may buy or sell
derivative instruments such as financial futures contracts and related options,
such as municipal bond index futures contracts and the related put or call
options contracts on such index futures. A tax exempt bond index fluctuates with
changes in the market values of the tax exempt bonds included in the index. An
index future is an agreement pursuant to which two parties agree to receive or
deliver at settlement an amount of cash equal to a specified dollar amount
multiplied by the difference between the value of the index at the close of the
last trading day of the contract and the price at which the future was
originally written. A financial future is an agreement between two parties to
buy and sell a security for a set price on a future date. An index future has
similar characteristics to a financial future except that settlement is made
through delivery of cash rather than the underlying securities. An example is
the Long-Term Municipal Bond futures contract traded on the Chicago Board of
Trade. It is based on the Bond Buyer's Municipal Bond Index, which represents an
adjusted average price of the forty most recent long-term municipal issues of
$50 million or more ($75 million in the instance of housing issues) rated A or
better by either Moody's Investors Service, Inc. ("Moody's") or Standard &
Poor's Ratings Group ("S&P"), maturing in no less than nineteen years, having a
first call in no less than seven nor more than sixteen years, and callable at
par.
 
  The Fund may engage in "when issued" and "delayed delivery" transactions and
utilize futures contracts and options thereon for hedging purposes. The
Securities and Exchange Commission ("SEC") generally requires that when mutual
funds, such as the Fund, effect transactions of the foregoing nature, such funds
must either segregate cash or readily marketable portfolio securities with its
custodian in an amount of its obligations under the foregoing transactions, or
cover such obligations by maintaining positions in portfolio securities, futures
contracts or options that would serve to satisfy or offset the risk of such
obligations. When effecting transactions of the foregoing nature, the Fund will
comply with such segregation or cover requirements.
 
STRATEGIC TRANSACTIONS.
 
  The Fund may, but is not required to, utilize various other investment
strategies as described below to hedge various market risks (such as interest
rates and broad or specific market movements) or to manage the effective
maturity or duration of the Fund's fixed-income securities. Such strategies are
generally accepted by modern portfolio managers and are regularly utilized by
many mutual funds and other institutional investors. Techniques and instruments
may change over time as new instruments and strategies are developed or
regulatory changes occur.
 
  In the course of pursuing these investment strategies, the Fund may purchase
and sell derivative instruments such as exchange-listed and over-the-counter put
and call options on securities, fixed-income indices and other financial
instruments, purchase and sell financial futures contracts and options thereon,
enter into various interest rate transactions such as swaps, caps, floors or
collars (collectively, all the above are called "Strategic Transactions").
Strategic Transactions may be used to attempt to protect against possible
changes in the market value of securities held in or to be purchased for the
Fund's portfolio resulting from securities markets fluctuations, to protect the
Fund's unrealized gains in the value of its portfolio securities, to facilitate
the sale of such securities for investment purposes, to manage the effective
maturity or duration of the Fund's portfolio, or to establish a position in the
derivatives markets as a temporary substitute for purchasing or selling
particular securities.
 
  Any or all of these investment techniques may be used at any time and there is
no particular strategy that dictates the use of one technique rather than
another, as use of any Strategic Transaction is a function of numerous variables
including market conditions. The ability of the Fund to utilize these Strategic
Transactions successfully will depend on the Adviser's ability to predict
pertinent market movements, which cannot be
 
                                       B-6
<PAGE>   463
 
assured. The Fund will comply with applicable regulatory requirements when
implementing these strategies, techniques and instruments. Strategic
Transactions involving financial futures and options thereon will be purchased,
sold or entered into only for bona fide hedging, risk management or portfolio
management purposes and not for speculative purposes.
 
  Strategic Transactions have risks associated with them including possible
default by the other party to the transaction, illiquidity and, to the extent
the Adviser's view as to certain market movements is incorrect, the risk that
the use of such Strategic Transactions could result in losses greater than if
they had not been used. Use of put and call options may result in losses to the
Fund, force the sale or purchase of portfolio securities at inopportune times or
for prices other than current market values, limit the amount of appreciation
the Fund can realize on its investments or cause the Fund to hold a security it
might otherwise sell. The use of options and futures transactions entails
certain other risks. In particular, the variable degree of correlation between
price movements of futures contracts and price movements in the related
portfolio position of the Fund creates the possibility that losses on the
hedging instrument may be greater than gains in the value of the Fund's
position. In addition, futures and options markets may not be liquid in all
circumstances and certain over-the-counter options may have no markets. As a
result, in certain markets, the Fund might not be able to close out a
transaction without incurring substantial losses, if at all. Although the use of
futures and options transactions for hedging should tend to minimize the risk of
loss due to a decline in the value of the hedged position, at the same time they
tend to limit any potential gain which might result from an increase in value of
such position. Finally, the daily variation margin requirements for futures
contracts would create a greater ongoing potential financial risk than would
purchases of options, where the exposure is limited to the cost of the initial
premium. Losses resulting from the use of Strategic Transactions would reduce
net asset value, and possibly income, and such losses can be greater than if the
Strategic Transactions had not been utilized. Income earned or deemed to be
earned, if any, by the Fund from its Strategic Transactions will generally be
taxable income of the Fund. See "Tax Status" in the Prospectus.
 
  GENERAL CHARACTERISTICS OF OPTIONS.   Put options and call options typically
have similar structural characteristics and operational mechanics regardless of
the underlying instrument on which they are purchased or sold. Thus, the
following general discussion relates to each of the particular types of options
discussed in greater detail below. In addition, many Strategic Transactions
involving options require segregation of Fund assets in special accounts, as
described below under "Use of Segregated and Other Special Accounts."
 
  A put option gives the purchaser of the option, upon payment of a premium, the
right to sell, and the writer the obligation to buy, the underlying security,
commodity, index, or other instrument at the exercise price. For instance, the
Fund's purchase of a put option on a security might be designed to protect its
holdings in the underlying instrument (or, in some cases, a similar instrument)
against a substantial decline in the market value by giving the Fund the right
to sell such instrument at the option exercise price. A call option, upon
payment of a premium, gives the purchaser of the option the right to buy, and
the seller the obligation to sell, the underlying instrument at the exercise
price. The Fund's purchase of a call option on a security, financial future,
index, or other instrument might be intended to protect the Fund against an
increase in the price of the underlying instrument that it intends to purchase
in the future by fixing the price at which it may purchase such instrument. An
American style put or call option may be exercised at any time during the option
period while a European style put or call option may be exercised only upon
expiration or during a fixed period prior thereto. The Fund is authorized to
purchase and sell exchange listed options and over-the-counter options ("OTC
options"). Exchange listed options are issued by a regulated intermediary such
as the Options Clearing Corporation ("OCC"), which guarantees the performance of
the obligations of the parties to such options. The discussion below uses the
OCC as a paradigm, but is also applicable to other financial intermediaries.
 
  With certain exceptions, OCC issued and exchange listed options generally
settle by physical delivery of the underlying security or currency, although in
the future cash settlement may become available. Index options and Eurodollar
instruments are cash settled for the net amount, if any, by which the option is
"in-the-money" (i.e., where the value of the underlying instrument exceeds, in
the case of a call option, or is less than, in the case of a put option, the
exercise price of the option) at the time the option is exercised. Frequently,
rather than taking or making delivery of the underlying instrument through the
process of exercising the option, listed
 
                                       B-7
<PAGE>   464
 
options are closed by entering into offsetting purchase or sale transactions
that do not result in ownership of the new option.
 
  The Fund's ability to close out its position as a purchaser or seller of an
OCC or exchange listed put or call option is dependent, in part, upon the
liquidity of the option market. Among the possible reasons for the absence of a
liquid option 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 including
reaching daily price limits; (iv) interruption of the normal operations of the
OCC or an exchange; (v) inadequacy of the facilities of an exchange or 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 relevant market for that option on that exchange would cease
to exist, although outstanding options on that exchange would generally continue
to be exercisable in accordance with their terms.
 
  The hours of trading for listed options may not coincide with the hours during
which the underlying financial instruments are traded. To the extent that the
option markets close before the markets for the underlying financial
instruments, significant price and rate movements can take place in the
underlying markets that cannot be reflected in the option markets.
 
  OTC options are purchased from or sold to securities dealers, financial
institutions or other parties ("Counterparties") through direct bilateral
agreement with the Counterparty. In contrast to exchange listed options, which
generally have standardized terms and performance mechanics, all the terms of an
OTC option, including such terms as method of settlement, term, exercise price,
premium, guarantees and security, are set by negotiation of the parties. The
Fund will only sell OTC options that are subject to a buy-back provision
permitting the Fund to require the Counterparty to sell the option back to the
Fund at a formula price within seven days. The Fund expects generally to enter
into OTC options that have cash settlement provisions, although it is not
required to do so.
 
  Unless the parties provide for it, there is no central clearing or guaranty
function in an OTC option. As a result, if the Counterparty fails to make or
take delivery of the security, or other instrument underlying an OTC option it
has entered into with the Fund or fails to make a cash settlement payment due in
accordance with the terms of that option, the Fund will lose any premium it paid
for the option as well as any anticipated benefit of the transaction.
Accordingly, the Adviser must assess the creditworthiness of each such
Counterparty or any guarantor or credit enhancement of the Counterparty's credit
to determine the likelihood that the terms of the OTC option will be satisfied.
The Fund will engage in OTC option transactions only with United States
government securities dealers recognized by the Federal Reserve Bank of New York
as "primary dealers", or broker dealers, domestic or foreign banks or other
financial institutions which have received (or the guarantors of the obligation
of which have received) a short-term credit rating of "A-1" from S&P or "P-1"
from Moody's or an equivalent rating from any other nationally recognized
statistical rating organization ("NRSRO"). The staff of the SEC currently takes
the position that, in general, OTC options on securities other than U.S.
Government securities purchased by the Fund, and portfolio securities "covering"
the amount of the Fund's obligation pursuant to an OTC option sold by it (the
cost of the sell-back plus the in-the-money amount, if any) are illiquid, and
are subject to the Fund's limitation on investing no more than 15% of its assets
in illiquid securities.
 
  If the Fund sells a call option, the premium that it receives may serve as a
partial hedge, to the extent of the option premium, against a decrease in the
value of the underlying securities or instruments in its portfolio or will
increase the Fund's income. The sale of put options can also provide income.
 
  The Fund may purchase and sell call options on securities, including U.S.
Treasury and agency securities, municipal obligations, mortgage-backed
securities and Eurodollar instruments that are traded on U.S. and foreign
securities exchanges and in the over-the-counter markets. All calls sold by the
Fund must be "covered" (i.e., the Fund must own the securities or futures
contract subject to the call) or must meet the asset segregation requirements
described below as long as the call is outstanding. Even though the Fund will
receive the option premium to help protect it against loss, a call sold by the
Fund exposes the Fund during the term of the option to possible loss of
opportunity to realize appreciation in the market price of the underlying
 
                                       B-8
<PAGE>   465
 
security or instrument and may require the Fund to hold a security or instrument
which it might otherwise have sold.
 
  The Fund may purchase and sell put options on securities including U.S.
Treasury and agency securities, mortgage-backed securities, municipal
obligations and Eurodollar instruments (whether or not it holds the above
securities in its portfolio.) The Fund will not sell put options if, as a
result, more than 50% of the Fund's assets would be required to be segregated to
cover its potential obligations under such put options other than those with
respect to futures and options thereon. In selling put options, there is a risk
that the Fund may be required to buy the underlying security at a
disadvantageous price above the market price.
 
  GENERAL CHARACTERISTICS OF FUTURES.  The Fund may enter into financial futures
contracts or purchase or sell put and call options on such futures as a hedge
against anticipated interest rate or fixed-income market changes, for duration
management and for risk management purposes. Futures are generally bought and
sold on the commodities exchanges where they are listed with payment of initial
and variation margin as described below. The purchase of a futures contract
creates a firm obligation by the Fund, as purchaser, to take delivery from the
seller the specific type of financial instrument called for in the contract at a
specific future time for a specified price (or, with respect to index futures
and Eurodollar instruments, the net cash amount). The sale of a futures contract
creates a firm obligation by the Fund, as seller, to deliver to the buyer the
specific type of financial instrument called for in the contract at a specific
future time for a specified price (or, with respect to index futures and
Eurodollar instruments, the net cash amount). Options on futures contracts are
similar to options on securities except that 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 and obligates the seller to deliver such option.
 
  The Fund's use of financial futures and options thereon will in all cases be
consistent with applicable regulatory requirements and in particular the rules
and regulations of the Commodity Futures Trading Commission and will be entered
into only for bona fide hedging, risk management (including duration management)
or other portfolio management purposes. Typically, maintaining a futures
contract or selling an option thereon requires the Fund to deposit with a
financial intermediary as security for its obligations an amount of cash or
other specified assets (initial margin) which initially is typically 1% to 10%
of the face amount of the contract (but may be higher in some circumstances).
Additional cash or assets (variation margin) may be required to be deposited
thereafter on a daily basis as the mark to market value of the contract
fluctuates. The purchase of options on financial futures involves payment of a
premium for the option without any further obligation on the part of the Fund.
If the Fund exercises an option on a futures contract it will be obligated to
post initial margin (and potential subsequent variation margin) for the
resulting futures position just as it would for any position. Futures contracts
and options thereon are generally settled by entering into an offsetting
transaction but there can be no assurance that the position can be offset prior
to settlement at an advantageous price nor that delivery will occur.
 
  The Fund will not enter into a futures contract or related option (except for
closing transactions) if, immediately thereafter, the sum of the amount of its
initial margin and premiums on open futures contracts and options thereon would
exceed 5% of the Fund's total assets (taken at current value); however, in the
case of an option that is in-the-money at the time of the purchase, the
in-the-money amount may be excluded in calculating the 5% limitation. The
segregation requirements with respect to futures contracts and options thereon
are described below.
 
  OPTIONS ON SECURITIES INDICES AND OTHER FINANCIAL INDICES.  The Fund also may
purchase and sell call and put options on securities indices and other financial
indices and in so doing can achieve many of the same objectives it would achieve
through the sale or purchase of options on individual securities or other
instruments. Options on securities indices and other financial indices are
similar to options on a security or other instrument except that, rather than
settling by physical delivery of the underlying instrument, they settle by cash
settlement, i.e., an option on an index gives the holder the right to receive,
upon exercise of the option, an amount of cash if the closing level of the index
upon which the option is based exceeds, in the case of a call, or is less than,
in the case of a put, the exercise price of the option (except if, in the case
of an OTC option, physical delivery is specified). This amount of cash is equal
to the excess of the closing price of the index over the exercise price of the
option, which also may be multiplied by a formula value. The seller of the
option is obligated, in return for the premium received, to make delivery of
this amount. The gain or loss on an option
 
                                       B-9
<PAGE>   466
 
on an index depends on price movements in the instruments making up the market,
market segment, industry or other composite on which the underlying index is
based, rather than price movements in individual securities, as is the case with
respect to options on securities.
 
  COMBINED TRANSACTIONS.  The Fund may enter into multiple transactions,
including multiple options transactions, multiple futures transactions and
multiple interest rate transactions and any combination of futures, options and
interest rate transactions ("component" transactions), instead of a single
Strategic Transaction, as part of a single or combined strategy when, in the
opinion of the Adviser, it is in the best interests of the Fund to do so. A
combined transaction will usually contain elements of risk that are present in
each of its component transactions. Although combined transactions are normally
entered into based on the Adviser's judgment that the combined strategies will
reduce risk or otherwise more effectively achieve the desired portfolio
management goal, it is possible that the combination will instead increase such
risks or hinder achievement of the portfolio management objective.
 
  SWAPS, CAPS, FLOORS AND COLLARS.  Among the Strategic Transactions into which
the Fund may enter are interest rate and index swaps and the purchase or sale of
related caps, floors and collars. The Fund expects to enter into these
transactions primarily to preserve a return or spread on a particular investment
or portion of its portfolio, as a duration management technique or to protect
against any increase in the price of securities the Fund anticipates purchasing
at a later date. The Fund intends to use these transactions as hedges and not as
speculative investments and will not sell interest rate caps or floors where it
does not own securities or other instruments providing the income stream the
Fund may be obligated to pay. Interest rate swaps involve the exchange by the
Fund with another party of their respective commitments to pay or receive
interest, e.g., an exchange of floating rate payments for fixed rate payments
with respect to a notional amount of principal. An index swap is an agreement to
swap cash flows on a notional amount based on changes in the values of the
reference indices. The purchase of a cap entitles the purchaser to receive
payments on a notional principal amount from the party selling such cap to the
extent that a specified index exceeds a predetermined interest rate or amount.
The purchase of a floor entitles the purchaser to receive payments on a notional
principal amount from the party selling such floor to the extent that a
specified index falls below a predetermined interest rate or amount. A collar is
a combination of a cap and a floor that preserves a certain return within a
predetermined range of interest rates or values.
 
  The Fund will usually enter into swaps on a net basis, i.e., the two payment
streams are netted out in a cash settlement on the payment date or dates
specified in the instrument, with the Fund receiving or paying, as the case may
be, only the net amount of the two payments. Inasmuch as these swaps, caps,
floors and collars are entered into for good faith hedging purposes, the Adviser
and the Fund believe such obligations do not constitute senior securities under
the 1940 Act and, accordingly, will not treat them as being subject to its
borrowing restrictions. The Fund will not enter into any swap, cap, floor or
collar transaction unless, at the time of entering into such transaction, the
unsecured long-term debt of the Counterparty, combined with any credit
enhancements, is rated at least "A" by S&P or Moody's or has an equivalent
equity rating from an NRSRO or is determined to be of equivalent credit quality
by the Adviser. If there is a default by the Counterparty, the Fund may have
contractual remedies pursuant to the agreements related to the transaction. The
swap market has grown substantially in recent years with a large number of banks
and investment banking firms acting both as principals and agents utilizing
standardized swap documentation. As a result, the swap market has become
relatively liquid. Caps, floors and collars are more recent innovations for
which standardized documentation has not yet been fully developed and,
accordingly, they are less liquid than swaps.
 
   
  USE OF SEGREGATED AND OTHER SPECIAL ACCOUNTS.  Many Strategic Transactions, in
addition to other requirements, require that the Fund segregate liquid
high-grade assets with its custodian to the extent Fund obligations are not
otherwise "covered" through ownership of the underlying security, financial
instrument or currency. In general, either the full amount of any obligation by
the Fund to pay or deliver securities or assets must be covered at all times by
the securities, instruments or currency required to be delivered, or, subject to
any regulatory restrictions, an amount of cash or liquid securities at least
equal to the current amount of the obligation must be segregated with the
custodian. The segregated assets cannot be sold or transferred unless equivalent
assets are substituted in their place or it is no longer necessary to segregate
them. For example, a call option written by the Fund will require the Fund to
hold the securities subject to the call (or securities convertible into the
needed securities without additional consideration) or to segregate liquid
securities
    
 
                                      B-10
<PAGE>   467
 
   
sufficient to purchase and deliver the securities if the call is exercised. A
call option sold by the Fund on an index will require the Fund to own portfolio
securities which correlate with the index or to segregate liquid securities
equal to the excess of the index value over the exercise price on a current
basis. A put option written by the Fund requires the Fund to segregate liquid
securities equal to the exercise price.
    
 
  OTC options entered into by the Fund, including those on securities, financial
instruments or indices and OCC issued and exchange listed index options, will
generally provide for cash settlement. As a result, when the Fund sells these
instruments it will only segregate an amount of assets equal to its accrued net
obligations, as there is no requirement for payment or delivery of amounts in
excess of the net amount. These amounts will equal 100% of the exercise price in
the case of a non cash-settled put, the same as an OCC guaranteed listed option
sold by the Fund, or the in-the-money amount plus any sell-back formula amount
in the case of a cash-settled put or call. In addition, when the Fund sells a
call option on an index at a time when the in-the-money amount exceeds the
exercise price, the Fund will segregate, until the option expires or is closed
out, cash or cash equivalents equal in value to such excess. OCC issued and
exchange listed options sold by the Fund other than those above generally settle
with physical delivery, and the Fund will segregate an amount of assets equal to
the full value of the option. OTC options settling with physical delivery, or
with an election of either physical delivery or cash settlement, will be treated
the same as other options settling with physical delivery.
 
  In the case of a futures contract or an option thereon, the Fund must deposit
initial margin and possible daily variation margin in addition to segregating
assets sufficient to meet its obligation to purchase or provide securities or
currencies, or to pay the amount owed at the expiration of an index- based
futures contract. Such assets may consist of cash, cash equivalents, liquid debt
or equity securities or other acceptable assets.
 
   
  With respect to swaps, the Fund will accrue the net amount of the excess, if
any, of its obligations over its entitlements with respect to each swap on a
daily basis and will segregate an amount of cash or liquid securities having a
value equal to the accrued excess. Caps, floors and collars require segregation
of assets with a value equal to the Fund's net obligation, if any.
    
 
  Strategic Transactions may be covered by other means when consistent with
applicable regulatory policies. The Fund may also enter into offsetting
transactions so that its combined position, coupled with any segregated assets,
equals its net outstanding obligation in related options and Strategic
Transactions. For example, the Fund could purchase a put option if the strike
price of that option is the same or higher than the strike price of a put option
sold by the Fund. Moreover, instead of segregating assets if the Fund held a
futures or forward contract, it could purchase a put option on the same futures
or forward contract with a strike price as high or higher than the price of the
contract held. Other Strategic Transactions may also be offset in combinations.
If the offsetting transaction terminates at the time of or after the primary
transaction no segregation is required, but if it terminates prior to such time,
assets equal to any remaining obligation would need to be segregated.
 
  The Fund's activities involving Strategic Transactions may be limited by the
requirements of Subchapter M of the Code for qualification as a regulated
investment company. See "Tax Status" in the Prospectus.
 
  Illiquid Securities.  The Fund may invest up to 15% of its total assets in
illiquid securities, securities the disposition of which is subject to
substantial legal or contractual restrictions on resale and securities that are
not readily marketable. The sale of restricted and illiquid securities often
requires more time and results in higher brokerage charges or dealer discounts
and other selling expenses than does the sale of securities eligible for trading
on national securities exchanges or in the over-the-counter markets. Restricted
securities may sell at a price lower than similar securities that are not
subject to restrictions on resale. Restricted securities salable among qualified
institutional buyers without restriction pursuant to Rule 144A under the
Securities Act of 1933 that are determined to be liquid by the Adviser under
guidelines adopted by the Board of Trustees of the Trust (under which guidelines
the Adviser will consider factors such as trading activities and the
availability of price quotations), will not be treated as restricted securities
by the Fund pursuant to such rules. The Fund may, from time to time, adopt a
more restrictive limitation with respect to investment in illiquid and
restricted securities in order to comply with the most restrictive state
securities law, currently 10%. This policy does not include restricted
securities eligible for resale pursuant to Rule 144A under the Securities Act of
 
                                      B-11
<PAGE>   468
 
1933, as amended, which the Board of Trustees or the Fund's investment adviser
has determined under Board-approved guidelines to be liquid.
 
  INSURANCE.  As described in the Prospectus, the Fund will generally invest
only in municipal securities which are either pre-insured under a policy
obtained for such securities prior to the purchase of such securities or will be
insured under policies obtained by the Fund to cover otherwise uninsured
securities.
 
  Original Issue Insurance.  Original Issue Insurance is purchased with respect
to a particular issue of municipal securities by the issuer thereof or a third
party in conjunction with the original issuance of such municipal securities.
Under such insurance, the insurer unconditionally guarantees to the holder of
the insured municipal security the timely payment of principal and interest on
such obligation when and as such payments shall become due but shall not be paid
by the issuer, except that in the event of any acceleration of the due date of
the principal by reason of mandatory or optional redemption (other than
acceleration by reason of a mandatory sinking fund payment), default or
otherwise, the payments insured may be made in such amounts and at such times as
payments of principal would have been due had there not been such acceleration.
The insurer is responsible for such payments less any amounts received by the
holder from any trustee for the municipal security issuers or from any other
source. Original Issue Insurance generally does not insure payment on an
accelerated basis, the payment of any redemption premium (except with respect to
certain premium payments in the case of certain small issue industrial
development and pollution control municipal securities), the value of the Shares
of the Fund or the market value of municipal securities, or payments of any
under purchase price upon the tender of the municipal securities. Original Issue
Insurance does not insure against nonpayment of principal of or interest on
municipal securities resulting from the insolvency, negligence or any other act
or omission of the trustee or other paying agent for such obligations.
 
  In the event that interest on or principal of a municipal security covered by
insurance is due for payment but is unpaid by reason of nonpayment by the issuer
thereof, the applicable insurer will make payments to its fiscal agent (the
"Fiscal Agent") equal to such unpaid amounts of principal and interest not later
than one business day after the insurer has been notified that such nonpayment
has occurred (but not earlier than the date such payment is due). The Fiscal
Agent will disburse to the Fund the amount of principal and interest which is
then due for payment but is unpaid upon receipt by the Fiscal Agent of (i)
evidence of the Fund's right to receive payment of such principal and interest
and (ii) evidence, including any appropriate instruments of assignment, that all
of the rights of payment of such principal or interest then due for payment
shall thereupon vest in the insurer. Upon payment by the insurer of any
principal or interest payments with respect to any municipal securities, the
insurer shall succeed to the rights of the Fund with respect to such payment.
 
  Original Issue Insurance remains in effect as long as the municipal securities
covered thereby remain outstanding and the insurer remains in business,
regardless of whether the Fund ultimately disposes of such municipal securities.
Consequently, Original Issue Insurance may be considered to represent an element
of market value with respect to the municipal securities so insured, but the
exact effect, if any, of this insurance on such market value cannot be
estimated.
 
  Secondary Market Insurance.  Subsequent to the time of original issuance of a
municipal security, the Fund or a third party may, upon the payment of a single
premium, purchase insurance on such municipal security. Secondary Market
Insurance generally provides the same type of coverage as is provided by
Original Issue Insurance and, as is the case with Original Issue Insurance,
Secondary Market Insurance remains in effect as long as the municipal securities
covered thereby remain outstanding and the insurer remains in business,
regardless of whether the Fund ultimately disposes of such municipal securities.
All premiums respecting municipal securities covered by Original Issue Insurance
or Secondary Market Insurance are paid in advance by the issuer or other party
obtaining the insurance.
 
  One of the purposes of acquiring Secondary Market Insurance with respect to a
particular municipal security would be to enable the Fund to enhance the value
of such municipal security. The Fund, for example, might seek to purchase a
particular municipal security and obtain Secondary Market Insurance with respect
thereto if, in the opinion of the Adviser, the market value of such municipal
security, as insured, would exceed the current value of the municipal security
without insurance plus the cost of the Secondary Market Insurance. Similarly, if
the Fund owns but wishes to sell a municipal security that is then covered by
Portfolio Insurance, the Fund might seek to obtain Secondary Market Insurance
with respect thereto if, in the opinion
 
                                      B-12
<PAGE>   469
 
of the Adviser, the net proceeds of a sale by the Fund of such obligation, as
insured, would exceed the current value of such obligation plus the cost of the
Secondary Market Insurance.
 
  Portfolio Insurance.  The portfolio insurance policies obtained by the Fund
would insure the payment of principal and interest on specified eligible
municipal securities purchased by the Fund. Except as described below, Portfolio
Insurance generally provides the same type of coverage as is provided by
Original Issue Insurance or Secondary Market Insurance. Municipal securities
insured under one Portfolio Insurance policy generally would not be insured
under any other policy purchased by the Fund. A municipal security is eligible
for coverage under a policy if it meets certain requirements of the insurer.
Portfolio Insurance is intended to reduce financial risk, but the cost thereof,
and compliance with investment restrictions imposed under the policy will reduce
the yield to shareholders of the Fund. If a municipal security already is
covered by Original Issue Insurance or Secondary Market Insurance, the Fund is
not required to additionally insure any such municipal security under any policy
of Portfolio Insurance that the Fund may purchase.
 
  Portfolio Insurance policies are effective only as to municipal securities
owned and held by the Fund, and do not cover municipal securities for which the
contract for purchase fails. A "when-issued" municipal security will be covered
under a Portfolio Insurance policy upon the settlement date of the issue of such
"when-issued" municipal security.
 
  In determining whether to insure municipal securities held by the Fund, an
insurer will apply its own standards, which correspond generally to the
standards it has established for determining the insurability of new issues of
municipal securities. See "Original Issue Insurance" above.
 
  Each Portfolio Insurance policy will be non-cancellable and will remain in
effect so long as the Fund is in existence, the municipal securities covered by
the policy continue to be held by the Fund, and the Fund pays the premiums for
the policy. Each insurer generally will reserve the right at any time upon 90
days written notice to the Fund to refuse to insure any additional securities
purchased by the Fund after the effective date of such notice. The Board of
Trustees of the Fund generally will reserve the right to terminate each policy
upon seven days written notice to an insurer if it determines that the cost of
such policy is not reasonable in relation to the value of the insurance to the
Fund.
 
  Each Portfolio Insurance policy shall terminate as to any municipal security
that has been redeemed from or sold by the Fund on the date of such redemption
or the settlement date of such sale, and an insurer shall not have any liability
thereafter under a policy as to any such municipal security, except that if the
date of such redemption or the settlement date of such sale occurs after a
record date and before the related payment date with respect to any such
municipal security, the policy will terminate as to such municipal security on
the business day immediately following such payment date. Each policy will
terminate as to all municipal securities covered thereby on the date on which
the last of the covered municipal securities mature, are redeemed or are sold by
the Fund.
 
  One or more policies of Portfolio Insurance may provide the Fund, pursuant to
an irrevocable commitment of the insurer, with the option to exercise the right
to obtain permanent insurance ("Permanent Insurance") with respect to a
municipal security that is to be sold by the Fund. The Fund would exercise the
right to obtain Permanent Insurance upon payment of a single, predetermined
insurance premium payable from the proceeds of the sale of such municipal
security. It is expected that the Fund will exercise the right to obtain
Permanent Insurance for a municipal security only if, in the opinion of the
Adviser, upon such exercise the net proceeds from the sale by the Fund of such
obligation, as insured, would exceed the proceeds from the sale of such
obligation without insurance. The Permanent Insurance premium with respect to
each such obligation is determined based upon the insurability of each such
obligation of the date of purchase by the Fund and will not be increased or
decreased for any change in the creditworthiness of such obligation unless such
obligation is in default as to payment of principal or interest, or both. In
such event, the Permanent Insurance premium shall be subject to an increase
predetermined at the date of purchase by the Fund.
 
  Because such Portfolio Insurance policy will terminate as to municipal
securities sold by the Fund on the date of sale, in which event the insurer will
be liable only for those payments of principal and interest that are then due
and owing (unless Permanent Insurance is obtained by the Fund), the provision
for this insurance will not enhance the marketability of securities held by the
Fund, whether or not the securities are in default or
 
                                      B-13
<PAGE>   470
 
in significant risk of default. On the other hand, since Original Issue
Insurance and Secondary Market Insurance will remain in effect as long as
municipal securities covered thereby are outstanding, such insurance may enhance
the marketability of such securities even when such securities are in default or
in significant risk of default, but the exact effect, if any, on the
marketability cannot be estimated. Accordingly, the Fund may determine to retain
or, alternatively, to sell municipal securities by Original Issue Insurance or
Secondary Market Insurance that are in default or in significant risk of
default.
 
  It is anticipated that certain of the municipal securities to be purchased by
the Fund will be insured under policies obtained by persons other than the Fund.
In instances in which the Fund purchases municipal securities insured under
policies obtained by persons other than the Fund, the Fund does not pay the
premiums for such policies; rather the cost of such policies may be reflected in
a higher purchase price for such municipal securities. Accordingly, the yield on
such municipal securities may be lower than that on similar uninsured municipal
securities. Premiums for a Portfolio Insurance Policy generally are paid by the
Fund monthly, and are adjusted for purchases and sales of municipal securities
covered by the policy during the month. The yield on the Fund's portfolio is
reduced to the extent of the insurance premiums paid by the Fund which, in turn,
will depend upon the characteristics of the covered municipal securities held by
the Fund. In the event the Fund were to purchase Secondary Market Insurance with
respect to any municipal securities then covered by a Portfolio Insurance
policy, the coverage and the obligation of the Fund to pay monthly premiums
under such policy would cease with such purchase.
 
  There can be no assurance that insurance of the kind described above will
continue to be available to the Fund. In the event that such insurance is no
longer available or that the cost of such insurance outweighs the benefits to
the Fund in the view of the Board of Trustees, the Board will consider whether
to modify the investment policies of the Fund, which may require the approval of
shareholders. In the event the claims-paying ability rating of an insurer of
municipal securities in the Fund's portfolio were to be lowered from AAA by S&P,
or if the Adviser anticipates such a lowering or otherwise does not believe an
insurer's claims-paying ability merits its existing triple-A rating, the Fund
could seek to obtain additional insurance from an insurer whose claims-paying
ability is rated AAA by S&P or, if the Adviser determines that the cost of
obtaining such additional insurance outweigh the benefits, the Fund may elect
not to obtain additional insurance. In making such determination, the Adviser
will consider the cost of the additional insurance, the new claims-paying
ability rating and financial condition of the existing insurer and the
creditworthiness of the issuer and/or guarantor of the underlying municipal
securities. The Adviser also may determine not to purchase additional insurance
in such circumstances if it believes that the insurer is taking steps which will
cause its triple-A claims-paying ability rating to be restored promptly.
 
  Although the Adviser periodically reviews the financial condition of each
insurer, there can be no assurance that the insurers will be able to honor their
obligations under all circumstances. In that regard, it should be noted that the
claims-paying abilities and debt ratings of several large insurers (at least one
of which insured municipal securities) recently have been lowered by one or more
of the nationally recognized securities rating agencies and that many insurers
currently are experiencing adverse results in their investment portfolios. In
addition, certain insurers' operations recently have been assumed by their state
regulatory agencies. The Fund cannot predict the consequences of a state
takeover of an insurer's obligations and, in particular, whether such an insurer
(or its state regulatory agency) could or would honor all of the insurer's
contractual obligations including any outstanding insurance contracts insuring
the timely payment of principal and interest on municipal securities. The Fund
cannot predict the impact which such events might have on the market values of
such municipal security. In the event of a default by an insurer on its
obligations with respect to any municipal securities in the Fund's portfolio,
the Fund would look to the issuer and/or guarantor of the relevant municipal
securities for payments of principal and interest and such issuer and/or
guarantor may not be rated AAA by S&P. Accordingly, the Fund could be exposed to
greater risk of non-payment in such circumstances which could adversely affect
the Fund's net asset value and the market price per Share. Alternatively, the
Fund could elect to dispose of such municipal securities; however, the market
prices for such municipal securities may be lower than the Fund's purchase price
for them and the Fund could sustain a capital loss as a result.
 
  Although the insurance on municipal securities reduces financial or credit
risk in respect of the insured obligations (i.e., the possibility that owners of
the insured municipal securities will not receive timely
 
                                      B-14
<PAGE>   471
 
scheduled payments of principal or interest), insured municipal securities
remain subject to market risk (i.e., fluctuations in market value as a result of
changes in prevailing interest rates). Accordingly, insurance on municipal
securities does not insure the market value of the Fund's assets or the net
asset value or the market price for the Shares.
 
  AMBAC Indemnity Corporation.  AMBAC Indemnity is a Wisconsin-domiciled stock
insurance corporation regulated by the Insurance Department of the State of
Wisconsin and licensed to do business in 50 states and the District of Columbia.
On December 31, 1991, AMBAC Indemnity had admitted assets of approximately
$1,431,000,000, total liabilities of approximately $684,400,000 and statutory
capital of approximately $830,000,000. Statutory capital consists of AMBAC
Indemnity's policyholders' surplus and statutory contingency reserve. AMBAC
Indemnity was formerly a wholly-owned subsidiary of Citicorp Financial Guaranty
Holdings, Inc. ("Holdings") (formerly known as AMBAC Inc.), a financial holding
company and itself a wholly-owned subsidiary of Citibank, N.A. ("Citibank").
According to Best Insurance Report (1991 edition), AMBAC Indemnity's aggregate
exposure under all Class I (municipal bond insurance) financial guaranty bonds,
the only class set forth therein, in force as of December 31, 1990 was
$86,200,000,000.
 
  On May 1, 1991, AMBAC Inc. ("AMBAC Inc."), a financial holding company formed
by Holdings, registered for sale with the Securities and Exchange Commission
17,600,000 shares of its common stock. The registration statement with respect
to such sale was declared effective on July 11, 1991. As a result of the sale,
Citibank, through its affiliate Holdings, owns approximately 49% of the total
equity of AMBAC Inc., with a right to cast 20% of the total number of votes of
all shares of outstanding common stock of AMBAC Inc. until such time as
Citibank, including its affiliates, reduces its equity ownership to less than
25% of AMBAC Inc. (at which time the shares owned by it become non-voting). As
of the date of the consummation of the sale of common stock, AMBAC Indemnity
became a direct wholly owned subsidiary of AMBAC Inc. The Wisconsin Insurance
Department has stated that the sale of common stock described herein does not
require its prior approval. Both Moody's and S&P have reaffirmed that the sale
of the common stock of AMBAC Inc. does not affect AMBAC Indemnity's triple-A
claims-paying ability ratings.
 
  AMBAC Indemnity has entered into pro rata reinsurance agreements under which a
percentage of the insurance underwritten pursuant to certain municipal bond
insurance programs of AMBAC Indemnity has been and will be assumed by a number
of foreign and domestic unaffiliated reinsurers.
 
  Copies of AMBAC Indemnity's financial statements prepared in accordance with
statutory accounting standards are available from AMBAC Indemnity. The address
of AMBAC Indemnity's administrative offices and its telephone number are One
State Street Plaza, 17th Floor, New York, New York 10004 and (212) 668-0340.
 
                  DESCRIPTION OF MUNICIPAL SECURITIES RATINGS
 
  STANDARD & POOR'S RATINGS GROUP--A brief description of the applicable
Standard & Poor's Ratings Group (S&P) rating symbols and their meanings (as
published by S&P) follows:
 
     1.  DEBT
 
   
          A S&P corporate or municipal debt rating is a current assessment of
     the creditworthiness of an obligor with respect to a specific obligation.
     This assessment may take into consideration obligors such as guarantors,
     insurers, or lessees.
    
 
          The debt rating is not a recommendation to purchase, sell or hold a
     security, inasmuch as it does not comment as to market price or suitability
     for a particular investor.
 
          The ratings are based on current information furnished by the issuer
     or obtained by S&P from other sources it considers reliable. S&P 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 based on other circumstances.
 
                                      B-15
<PAGE>   472
 
        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;
 
        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.
 
<TABLE>
    <S>         <C>
    AAA         Debt rated 'AAA' has the highest rating assigned by S&P.
                Capacity to pay interest and repay principal is extremely
                strong.
 
    AA          Debt rated 'AA' has a very strong capacity to pay interest
                and repay principal and differs from the higher rated issues
                only in small degree.
 
    A           Debt rated 'A' has a strong capacity to pay interest and
                repay principal although it is somewhat more susceptible to
                the adverse effects of changes in circumstances and economic
                conditions than debt in higher rated categories.
 
    BBB         Debt rated 'BBB' is regarded as having an adequate capacity
                to pay interest and repay principal. Whereas it normally
                exhibits adequate protection parameters, adverse economic
                conditions or changing circumstances are more likely to lead
                to a weakened capacity to pay interest and repay principal
                for debt in this category than in higher rated categories.
 
    BB          Debt rated 'BB', 'B', 'CCC', 'CC' and 'C' is regarded, on
    B           balance, as predominantly speculative with respect to
    CCC         capacity to pay interest and repay principal. 'BB' indicates
    CC          the least degree of speculation and 'C' the highest. While
    C           such debt will likely have some quality and protective
                characteristics, these are outweighed by large uncertainties
                or large exposures to adverse conditions.
 
    BB          Debt rated 'BB' has less near-term vulnerability to default
                than other speculative issues. However, it faces major
                ongoing uncertainties or exposure to adverse business,
                financial, or economic conditions which could lead to
                inadequate capacity to meet timely interest and principal
                payments. The 'BB' rating category is also used for debt
                subordinated to senior debt that is assigned an actual or
                implied 'BBB-' rating.
 
    B           Debt rated 'B' has a greater vulnerability to default but
                currently has the capacity to meet interest payments and
                principal repayments. Adverse business, financial, or
                economic conditions will likely impair capacity or
                willingness to pay interest and repay principal. The 'B'
                rating category is also used for debt subordinated to senior
                debt that is assigned an actual or implied 'BB' or 'BB-'
                rating.
 
    CCC         Debt rated 'CCC' has a currently identifiable vulnerability
                to default, and is dependent upon favorable business,
                financial, and economic conditions to meet timely payment of
                interest and repayment of principal. In the event of adverse
                business, financial, or economic conditions, it is not
                likely to have the capacity to pay interest and repay
                principal. The 'CCC' rating category is also used for debt
                subordinated to senior debt that is assigned an actual or
                implied 'B' or 'B-' rating.
 
    CC          The rating 'CC' typically is applied to debt subordinated to
                senior debt that is assigned an actual or implied 'CCC'
                rating.
 
    C           The rating 'C' typically is applied to debt subordinated to
                senior debt which is assigned an actual or implied 'CCC-'
                debt rating. The 'C' rating may be used to cover a situation
                where a bankruptcy petition has been filed, but debt service
                payments are continued.
 
    CI          The rating 'CI' is reserved for income bonds on which no
                interest is being paid.

<PAGE>   473
<TABLE>
    <S>         <C>
    D           Debt rated 'D' is in payment default. The 'D' rating
                category is used when interest payments or principal
                payments are not made on the date due even if the applicable
                grace period has not expired, unless S&P believes that such
                payments will be made during such grace period. The 'D'
                rating also will be used upon the filing of a bankruptcy
                petition if debt service payments are jeopardized.
 
                PLUS (+) or MINUS (-): The ratings from 'AA' to 'CCC' may be
                modified by the addition of a plus or minus sign to show
                relative standing within the major categories.
 
    C           The letter "c" indicates that the holder's option to tender
                the security for purchase may be canceled under certain
                prestated conditions enumerated in the tender option
                documents.
 
    I           The letter "i" indicates the rating is implied. Such ratings
                are assigned only on request to entities that do not have
                specific debt issues to be rated. In addition, implied
                ratings are assigned to governments that have not requested
                explicit ratings for specific debt issues. Implied ratings
                on governments represent the sovereign ceiling or upper
                limit for ratings on specific debt issues of entities
                domiciled in the country.
 
    L           The letter "L" indicates that the rating pertains to the
                principal amount of those bonds to the extent that the
                underlying deposit collateral is federally insured and
                interest is adequately collateralized. In the case of
                certificates of deposit, the letter "L" indicates that the
                deposit, combined with other deposits being held in the same
                right and capacity, will be honored for principal and
                accrued pre-default interest up to the federal insurance
                limits within 30 days after closing of the insured
                institution or, in the event that the deposit is assumed by
                a successor insured institution, upon maturity.
 
    P           The letter "p" indicates that the rating is provisional. A
                provisional rating assumes the successful completion of the
                project being financed by the debt being rated and indicates
                that payment of debt service requirements is largely or
                entirely dependent upon the successful and timely completion
                of the project. This rating, however, while addressing
                credit quality subsequent to completion of the project,
                makes no comment on the likelihood of, or the risk of
                default upon failure of, such completion. The investor
                should exercise his own judgement with respect to such
                likelihood and risk.
 
                * Continuance of the rating is contingent upon S&P's receipt
                of an executed copy of the escrow agreement or closing
                  documentation confirming investments and cash flows.
 
    NR          Indicates that no public rating has been requested, that
                there is insufficient information on which to base a rating,
                or that S&P does not rate a particular type of obligation as
                a matter of policy.
</TABLE>
 
          DEBT OBLIGATIONS OF ISSUERS OUTSIDE THE UNITED STATES AND ITS
     TERRITORIES are rated on the same basis as domestic corporate and municipal
     issues. The ratings measure the creditworthiness of the obligor but do not
     take into account currency exchange and related uncertainties.
 
          BOND INVESTMENT QUALITY STANDARDS--Under present commercial bank
     regulations issued by the Comptroller of the Currency, bonds rated in the
     top four categories ("AAA", "AA", "A", "BBB", commonly known as "investment
     grade" ratings) are generally regarded as eligible for bank investment. In
     addition, the laws of various states governing legal investments impose
     certain rating or other standards for obligations eligible for investment
     by savings banks, trust companies, insurance companies, and fiduciaries
     generally.
 
     2.  MUNICIPAL NOTES
 
   
          A S&P note rating reflects the liquidity concerns and market access
     risks unique to notes. Notes maturing in 3 years or less will likely
     receive a note rating. Notes maturing beyond 3 years will most likely
     receive a long-term debt rating.
    
 
          The following criteria will be used in making that assessment.
 
                                      B-17
<PAGE>   474
 
          -- Amortization schedule (the larger the final maturity relative to
             other maturities, the more likely the issue is to be treated as a
             note).
 
          -- Source of payment (the more the issue depends on the market for its
             refinancing, the more likely it is to be treated as a note).
 
        Note rating symbols are as follows:
 
<TABLE>
    <S>         <C>
    SP-1        Strong capacity to pay principal and interest. Issues
                determined to possess very strong characteristics are a plus
                (+) designation.
 
    SP-2        Satisfactory capacity to pay principal and interest, with
                some vulnerability to adverse financial and economic changes
                over the term of the notes.
 
    SP-3        Speculative capacity to pay principal and interest.
</TABLE>
 
     3.  COMMERCIAL PAPER
 
   
          A S&P 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.
    
 
          Ratings are graded into several categories, ranging from 'A-1' for the
     highest-quality obligations to 'D' for the lowest. These categories are as
     follows:
 
<TABLE>
    <S>         <C>
    A-1         This highest category indicates that the degree of safety
                regarding timely payment is strong. Those issues determined
                to possess extremely strong safety characteristics are
                denoted with a plus (+) sign designation.
 
    A-2         Capacity for timely payment on issues with this designation
                is satisfactory. However, the relative degree of safety is
                not as high as for issues designated 'A-1'.
 
    A-3         Issues carrying this designation have adequate capacity for
                timely payment. They are, however, more vulnerable to the
                adverse effects of changes in circumstances than obligations
                carrying the higher designations.
 
    B           Issues rated 'B' are regarded as having only speculative
                capacity for timely payment.
 
    C           This rating is assigned to short-term debt obligations with
                a doubtful capacity for payment.
 
    D           Debt rated 'D' is in payment default. The 'D' rating
                category is used when interest payments or principal
                payments are not made on the date due, even if the
                applicable grace period has not expired, unless S&P believes
                that such payments will be made during such grace period.
 
    A commercial paper rating is not a recommendation to purchase, sell a
    security. The ratings are based on current information furnished to S&P
    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.
</TABLE>
 
                                      B-18
<PAGE>   475
 
     4.  TAX-EXEMPT DUAL RATINGS
 
   
          S&P assigns "dual" ratings to all debt issues that have a put option
     or demand feature as part of their structure.
    
 
          The first rating addresses the likelihood of repayment of principal
     and interest as due, and the second rating addresses only the demand
     feature. The long-term debt rating symbols are used for bonds to denote the
     long-term maturity and the commercial paper rating symbols for the put
     option (for example, 'AAA/A-1+'). With short-term demand debt, S&P's note
     rating symbols are used with the commercial paper symbols (for example,
     'SP-1+/A-1+').
 
  MOODY'S INVESTORS SERVICE--A brief description of the applicable Moody's
Investors Service ("Moody's") rating symbols and their meanings (as published by
Moody's) follows:
 
     1.  LONG-TERM MUNICIPAL BONDS
 
<TABLE>
    <S>         <C>
    AAA         Bonds which are rated Aaa are judged to be of the best
                quality. They carry the smallest degree of investment risk
                and are generally referred to as "gilt edged." Interest
                payments are protected by a large or by an exceptionally
                stable margin and principal is secure. While the various
                protective elements are likely to change, such changes as
                can be visualized are most unlikely to impair the
                fundamentally strong position of such issues.
 
    AA          Bonds which are rated Aa are judged to be of high quality by
                all standards. Together with the Aaa group they comprise
                what are generally known as high grade bonds. They are rated
                lower than the best bonds because margins of protection may
                not be as large as in Aaa securities or fluctuation of
                protective elements may be of greater amplitude or there may
                be other elements present which make the long-term risk
                appear somewhat larger than the Aaa securities.
 
    A           Bonds which are rated A possess many favorable investment
                attributes and are to be considered as upper-medium-grade
                obligations. Factors giving security to principal and
                interest are considered adequate, but elements may be
                present which suggest a susceptibility to impairment some
                time in the future.
 
    BAA         Bonds which are rated Baa are considered as medium-grade
                obligations, (i.e., they are neither highly protected nor
                poorly secured). Interest payments and principal security
                appear adequate for the present but certain protective
                elements may be lacking or may be characteristically
                unreliable over any great length of time. Such bonds lack
                outstanding investment characteristics and in fact have
                speculative characteristics as well.
 
    BA          Bonds which are rated Ba are judged to have speculative
                elements; their future cannot be considered as well-assured.
                Often the protection of interest and principal payments may
                be very moderate, and thereby not well safeguarded during
                both good and bad times over the future. Uncertainty of
                position characterizes bonds in this class.
 
    B           Bonds which are rated B generally lack characteristics of
                the desirable investment. Assurance of interest and
                principal payments or of maintenance of other terms of the
                contract over any long period of time may be small.
 
    CAA         Bonds which are rated Caa are of poor standing. Such issues
                may be in default or there may be present elements of danger
                with respect to principal or interest.
 
    CA          Bonds which are rated Ca represent obligations which are
                speculative in a high degree. Such issues are often in
                default or have other marked shortcomings.
 
    C           Bonds which are rated C are the lowest rated class of bonds,
                and issues so rated can be regarded as having extremely poor
                prospects of ever attaining any real investment standing.

    CON (..)    Bonds for which the security depends upon the completion of
                some act or the fulfillment of some condition are rated
                conditionally and designated with the prefix "Con" followed
                by the rating in parentheses. These are bonds secured by:
                (a) earnings of projects under construction, (b) earnings of
                projects unseasoned in operation experience, (c) rentals
                which begin when facilities are completed, or (d) payments
                to which some other limiting condition attaches the
                parenthetical rating denotes probable credit stature upon
                completion of construction or elimination of basis of
                condition.
 
    (P) (..)    When applied to forward delivery bonds, indicates that the
                rating is provisional pending the delivery of the bonds. The
                rating may be revised prior to delivery if changes occur in
                the legal documents or the underlying credit quality of the
                bonds.
 
    NOTE:       Moody's applies numerical modifiers, 1, 2 and 3 in each
                generic rating classification from AA to B. The modifier 1
                indicates that the company ranks in the higher end of its
                generic rating category; the modifier 2 indicates a
                mid-range ranking; and the modifier 3 indicates that the
                company ranks in the lower end of its generic rating
                category.
 
    
 
     2.  SHORT-TERM EXEMPT NOTES
 
          Moody's ratings for state and municipal short-term obligations will be
     designated Moody's Investment Grade or (MIG). Such ratings recognize the
     differences between short-term credit risk and long-term risk. Factors
     affecting the liquidity of the borrower and short-term cyclical elements
     are critical in short-term ratings, while other factors of major importance
     in bond risk, long-term secular trends for example, may be less important
     over the short run. A short-term rating may also be assigned on an issue
     having a demand feature-variable rate demand obligation. Such ratings will
     be designated as VMIG, SG or, if the demand feature is not rated, as NR.
 
          Moody's short-term ratings are designated Moody's Investment Grade as
     MIG 1 or VMIG 1 through MIG 4 or VMIG 4. As the name implies, when Moody's
     assigns a MIG or VMIG rating, all categories define an investment grade
     situation.
 
          MIG 1/VMIG 1. This designation denotes best quality. There is present
     strong protection by established cash flows, superior liquidity support or
     demonstrated broad-based access to the market for refinancing.
 
          MIG 2/VMIG 2. This designation denotes high quality. Margins of
     protection are ample although not so large as in the preceding group.
 
          MIG 3/VMIG 3. This designation denotes favorable quality. All security
     elements are accounted for but there is lacking the undeniable strength of
     the preceding grades. Liquidity and cash flow protection may be narrow and
     market access for refinancing is likely to be less well established.
 
          MIG 4/VMIG 4. This designation denotes adequate quality. Protection
     commonly regarded as required of an investment security is present and
     although not distinctly or predominantly speculative, there is specific
     risk.
 
          SG. This designation denotes speculative quality. Debt instruments in
     this category lack margins of protection.
 
     3.  TAX-EXEMPT COMMERCIAL PAPER
 
   
          Moody's short-term debt ratings are opinions of the ability of issuers
     to repay punctually promissory obligations not having an original maturity
     in excess of nine months. Moody's makes no representation that such
     obligations are exempt from registration under the Securities Act of 1933,
     nor does it represent that any specific note is a valid obligation of a
     rated issuer or issued in conformity with any applicable law.
    
 
                                      B-20
<PAGE>   477
 
          Moody's employs the following three designations, all judged to be
     investment grade, to indicate the relative repayment ability of rated
     issuers:
 
   
       Issuers rated Prime-1 (for related supporting institutions) have a
     superior capacity for repayment of short-term promissory obligations.
     Prime-1 repayment capacity will normally be evidenced by the following
     characteristics:
    
 
   
         - Leading market positions in well established industries.
    
 
   
         - High rates of return on funds employed.
    
 
   
         - Conservative capitalization structures with moderate reliance on debt
           and ample asset protection.
    
 
   
         - Broad margins in earning coverage of fixed financial charges and high
           internal cash generation.
    
 
   
         - Well established access to a range of financial markets and assured
           sources of alternate liquidity.
    
 
   
       Issuers rated Prime-2 (or related supporting institutions) have a strong
     capacity for repayment of short-term promissory obligations. This will
     normally be evidenced by many of the characteristics cited above but to a
     lesser degree. Earnings trends and coverage ratios, while sound, will be
     more subject to variation. Capitalization characteristics, while still
     appropriate, may be more affected by external conditions. Ample alternate
     liquidity is maintained.
    
 
   
       Issuers rated Prime-3 (or related supporting institutions) have an
     acceptable capacity for repayment of short-term promissory obligations. The
     effects of industry characteristics and market composition may be more
     pronounced. Variability in earnings and profitability may result in changes
     in the level of debt protection measurements and the requirement for
     relatively high financial leverage. Adequate alternate liquidity is
     maintained.
    
 
   
       Issuers rated Not Prime do not fall within any of the Prime rating
     categories.

  Each of the trustees holds the same position with each of the funds in the
Fund Complex. As of December 31, 1996, there were 51 funds in the Fund Complex.
Each trustee who is not an affiliated person of VKAC, the Advisers, the
Distributor, ACCESS or Morgan Stanley (each a "Non-Affiliated Trustee") is
compensated by an annual retainer and meeting fees for services to the funds in
the Fund Complex. Each fund in the Fund Complex provides a deferred compensation
plan to its Non-Affiliated Trustees that allows trustees to defer receipt of
their compensation and earn a return on such deferred amounts based upon the
return of the common shares of the funds in the Fund Complex as more fully
described below. Each fund in the Fund Complex also provides a retirement plan
to its Non-Affiliated Trustees that provides Non-Affiliated Trustees with
compensation after retirement, provided that certain eligibility requirements
are met as more fully described below.
    
 
   
  The compensation of each Non-Affiliated Trustee from each fund in the Fund
Complex advised by Advisory Corp. (each a "VK Fund" and collectively the "VK
Funds") includes an annual retainer in an amount equal to $2,500 per calendar
year, due in four quarterly installments on the first business day of each
calendar quarter. Each Non-Affiliated Trustee receives a per meeting fee from
each VK Fund in the amount of $125 per regular quarterly meeting attended by the
Non-Affiliated Trustee, due on the date of such meeting, plus reasonable
expenses incurred by the Non-Affiliated Trustee in connection with his or her
services as a trustee. Each Non-Affiliated Trustee receives a per meeting fee
from each VK Fund in the amount of $125 per special meeting attended by the
Non-Affiliated Trustee, due on the date of such meeting, plus reasonable
expenses incurred by the Non-Affiliated Trustee in connection with his or her
services as a trustee, provided that no compensation will be paid in connection
with certain telephonic special meetings.
    
 
   
  The compensation of each Non-Affiliated Trustee from the funds in the Fund
Complex advised by Asset Management (each an "AC Fund" or collectively the "AC
Funds") includes an annual retainer in an amount equal to $35,000 per calendar
year, due in four quarterly installments on the first business day of each
calendar quarter. The AC Funds pay each Non-Affiliated Trustee a per meeting fee
in the amount of $2,000 per regular quarterly meeting attended by the
Non-Affiliated Trustee, due on the date of such meeting, plus reasonable
expenses incurred by the Non-Affiliated Trustee in connection with his or her
services as a trustee. Payment of the annual retainer and the regular meeting
fee is allocated among the AC Funds (i) 50% on the basis of the relative net
assets of each AC Fund to the aggregate net assets of all the AC Funds and (ii)
50% equally to each AC Fund, in each case as of the last business day of the
preceding calendar quarter. Each AC Fund which is the subject of a special
meeting of the trustees generally pays each Non-Affiliated Trustee a per meeting
fee in the amount of $125 per special meeting attended by the Non-Affiliated
Trustee, due on the date of such meeting, plus reasonable expenses incurred by
the Non-Affiliated Trustee in connection with his or her services as a trustee,
provided that no compensation will be paid in connection with certain telephonic
special meetings.
    
 
   
  The trustees approved an aggregate compensation cap with respect to funds in
the Fund Complex of $84,000 per Non-Affiliated Trustee per year (excluding any
retirement benefits) for the period July 22, 1995 through December 31, 1996,
subject to the net assets and the number of funds in the Fund Complex as of July
21, 1995 and certain other exceptions. For the calendar year ended December 31,
1996, certain trustees received aggregate compensation from the funds in the
Fund Complex over $84,000 due to compensation received but not subject to the
cap, including compensation from new funds added to the Fund Complex after July
22, 1995 and certain special meetings in 1996. In addition, each of Advisory
Corp. or Asset Management, as the case may be, agreed to reimburse each fund in
the Fund Complex through December 31, 1996 for any increase in the aggregate
trustee's compensation over the aggregate compensation paid by such fund in its
1994 fiscal year, provided that if a fund did not exist for the entire 1994
fiscal year appropriate adjustments will be made.
    
 
   
  Each Non-Affiliated Trustee generally can elect to defer receipt of all or a
portion of the compensation earned by such Non-Affiliated Trustee until
retirement. Amounts deferred are retained by the Fund and earn a rate of return
determined by reference to the return on the common shares of such Fund or other
funds in the Fund Complex as selected by the respective Non-Affiliated Trustee,
with the same economic effect as if such Non-Affiliated Trustee had invested in
one or more funds in the Fund Complex. To the extent permitted by the 1940 Act,
the Fund may invest in securities of those funds selected by the Non-Affiliated
Trustees in

order to match the deferred compensation obligation. The deferred compensation
plan is not funded and obligations thereunder represent general unsecured claims
against the general assets of the Fund.
    
 
   
  Each fund in the Fund Complex has adopted a retirement plan. Under the Fund's
retirement plan, a Non-Affiliated Trustee who is receiving trustee's
compensation from the Fund prior to such Non-Affiliated Trustee's retirement,
has at least 10 years of service (including years of service prior to adoption
of the retirement plan) and retires at or after attaining the age of 60, is
eligible to receive a retirement benefit equal to $2,500 per year for each of
the ten years following such trustee's retirement from the Fund. Trustees
retiring prior to the age of 60 or with fewer than 10 years but more than 5
years of service may receive reduced retirement benefits from the Fund. Each
trustee has served as a member of the Board of Trustees since he or she was
first appointed or elected in the year set forth below. The retirement plan
contains a Fund Complex retirement benefit cap of $60,000 per year. Asset
Management has reimbursed each AC Fund for the expenses related to the
retirement plan through December 31, 1996.
    
 
   
  Additional information regarding compensation and benefits for trustees is set
forth below. As indicated in the notes accompanying the table, the amounts
relate to either the Trust's most recently completed fiscal year or the Fund
Complex' most recently completed calendar year ended December 31, 1996.

*  Currently a member of the Board of Trustees. Mr. Phillip B. Rooney also is a
   current member of the Board of Trustees but is not included in the
   compensation table because he did not serve on the Board of Trustees or
   receive any compensation from the Trust prior to April 14, 1997. Messrs.
   McDonnell and Powell, also trustees of the Trust during all or a portion of
   the Trust's last fiscal year, are not included in the compensation table
   because they are affiliated persons of the Advisers and are not eligible for
   compensation or retirement benefits from the Trust.
    
 
   
(1) Persons not designated by an asterisk are not currently members of the Board
    of Trustees, but were members of the Board of Trustees during the Trust's
    most recently completed fiscal year. Messrs. Gaughan and Rees retired from
    the Board of Trustees on January 26, 1996 and January 29, 1996,
    respectively. Mr. Sheehan was removed from the Board of Trustees effective
    January 29, 1996. Messrs. Hilsman, Miller and Woodside retired from the
    Board of Trustees on December 31, 1996.
    
 
   
(2) The amounts shown in this column represent the aggregate compensation before
    deferral from all eight series of the Trust, including the Fund, with
    respect to the Trust's fiscal year ended December 31, 1996.

    The detail of aggregate compensation before deferral for each series,
    including the Fund, are shown in Table A below. Certain trustees deferred
    compensation from the Trust during the fiscal year ended December 31, 1996;
    the aggregate compensation deferred from all eight series of the Trust,
    including the Fund, is as follows: Mr. Branagan, $5,750; Mr. Gaughan,
    $3,750; Ms. Heagy, $15,000; Mr. Kennedy, $9,500; Mr. Miller, $20,000; Mr.
    Nelson, $20,000; Mr. Robinson, $18,000; and Mr. Whalen, $19,625. The details
    of amounts deferred for each series, including the Fund, are shown in Table
    B below. Amounts deferred are retained by the respective fund and earn a
    rate of return determined by reference to either the return on the common
    shares of such fund or other funds in the Fund Complex as selected by the
    respective Non-Affiliated Trustee, with the same economic effect as if such
    Non-Affiliated Trustee had invested in one or more funds in the Fund
    Complex. To the extent permitted by the 1940 Act, each fund may invest in
    securities of those funds selected by the Non-Affiliated Trustees in order
    to match the deferred compensation obligation. The cumulative deferred
    compensation (including interest) accrued with respect to each trustee from
    all eight series of the Trust, including the Fund, as of the Trust's fiscal
    year ended December 31, 1996 is as follows: Mr. Branagan, $5,678; Mr.
    Gaughan, $20,094; Ms. Heagy, $20,472; Mr. Kennedy, $47,294; Mr. Miller,
    $55,827; Mr. Nelson, $57,771; Mr. Robinson, $54,847; and Mr. Whalen,
    $49,269. The details of cumulative deferred compensation (including
    interest) for each series, including the Fund, are shown in Table C below.
    The deferred compensation plan is described above the Compensation Table.
    
 
   
(3) The amounts shown in this column represent the retirement benefits accrued
    by all eight series of the Trust, including the Fund, with respect to the
    Trust's fiscal year ended December 31, 1996. The details of retirement
    benefits accrued for each series, including the Fund, are shown in Table D
    below. The retirement plan is described above the Compensation Table.
    
 
   
(4) This is the estimated maximum annual benefits payable by the Trust in each
    year of the 10-year period commencing in the year of such trustee's
    retirement from the Trust. The estimated maximum annual benefit, except for
    trustees who have retired or are near retirement, is based upon $2,500 per
    series assuming: the trustee has 10 or more years of service on the Board of
    Trustees (including years of service prior to the adoption of the retirement
    plan) and retires at or after attaining the age of 60. Trustees retiring
    prior to the age of 60 or with fewer than 10 years of service for a series
    of the Trust may receive reduced retirement benefits from such series. The
    actual annual benefit may be less if the trustee is subject to the Fund
    Complex retirement benefit cap or if the trustee is not fully vested at the
    time of retirement. Each Non-Affiliated Trustee of the Board of Trustees has
    served as a member of the Board of Trustees since he or she was first
    appointed or elected in the year set forth in Table E below.
    
 
   
(5) The amounts shown in this column represent the aggregate compensation paid
    by all 51 of the investment companies in the Fund Complex as of December 31,
    1996 before deferral by the trustees under the deferred compensation plan.
    Certain trustees deferred all or a portion of their aggregate compensation
    from the Fund Complex during the calendar year ended December 31, 1996. The
    deferred compensation earns a rate of return determined by reference to the
    return on the shares of the funds in the Fund Complex as selected by the
    respective Non-Affiliated Trustee, with the same economic effect as if such
    Non-Affiliated Trustee had invested in one or more funds in the Fund
    Complex. To the extent permitted by the 1940 Act, the Fund may invest in
    securities of those investment companies selected by the Non-Affiliated
    Trustees in order to match the deferred compensation obligation. The
    trustees' Fund Complex compensation cap covered the period July 22, 1995
    through December 31, 1996. For the calendar year ended December 31, 1996,
    certain trustees received compensation over $84,000 in the aggregate due to
    compensation received but not subject to the cap, including compensation
    from new funds added to the Fund Complex after July 22, 1995 and certain
    special meetings in 1996. The Advisers and their affiliates also serve as
    investment adviser for other investment companies; however, with the
    exception of Messrs. McDonnell, Powell and Whalen, the trustees were not
    trustees of such investment companies. Combining the Fund Complex with other
    investment companies advised by the Advisers and their affiliates, Mr.
    Whalen received Total Compensation of $243,375 during the calendar year
    ended December 31, 1996.
    
 
   
  As of April 4, 1997, the trustees and officers of the Fund as a group owned
less than 1% of the shares of the Fund.

Fund's investment adviser. The Adviser was incorporated as a Delaware
corporation in 1982 (and through December 31, 1987 transacted business under the
name of American Portfolio Advisory Service Inc.).
    
 
   
  The Adviser is a wholly-owned subsidiary of Van Kampen American Capital, Inc.
("VKAC"), which is a wholly-owned subsidiary of VK/AC Holding, Inc. VK/AC
Holding, Inc. is a wholly-owned subsidiary of MSAM Holdings II, Inc. which, in
turn, is a wholly-owned subsidiary of Morgan Stanley Group Inc. The principal
office of the Fund, the Adviser, the Distributor and VKAC is located at One
Parkview Plaza, Oakbrook Terrace, Illinois 60181.
    
 
   
  Morgan Stanley Group Inc. and various of its directly or indirectly owned
subsidiaries, including Morgan Stanley & Co. Incorporated, a registered
broker-dealer and investment adviser, and Morgan Stanley International, are
engaged in a wide range of financial services. Their principal businesses
include securities underwriting, distribution and trading; merger, acquisition,

options, foreign exchange, commodities and swaps (involving foreign exchange,
commodities, indices and interest rates); real estate advice, financing and
investing; and global custody, securities clearance services and securities

  On February 5, 1997, Morgan Stanley Group Inc. and Dean Witter, Discover & Co.
announced that they had entered into an Agreement and Plan of Merger to form
Morgan Stanley, Dean Witter, Discover & Co. Subject to certain conditions being
met, it is currently anticipated that the transaction will close in mid-1997.
Thereafter, Van Kampen American Capital Asset Management, Inc. will be an
indirect subsidiary of Morgan Stanley, Dean Witter, Discover & Co.
    
 
   
  Dean Witter, Discover & Co. is a financial services company with three major
businesses; full service brokerage, credit services and asset management.
    
 
   
  The investment advisory agreement between the Adviser and the Fund provides
that the Adviser will supply investment research and portfolio management,
including the selection of securities for the Fund to purchase, hold or sell and
the selection of brokers through whom the Fund's portfolio transactions are
executed. The Adviser also administers the business affairs of the Fund,
furnishes offices, necessary facilities and equipment, provides administrative
services, and permits its officers and employees to serve without compensation
as trustees of the Trust and officers of the Fund if duly elected to such
positions.
    
 
  The agreement provides that the Adviser shall not be liable for any error of
judgment or of law, or for any loss suffered by the Fund in connection with the
matters to which the agreement relates, except a loss resulting from willful
misfeasance, bad faith or gross negligence on the part of the Adviser in the
performance of its obligations and duties, or by reason of its reckless
disregard of its obligations and duties under the agreement.

  The Adviser's activities are subject to the review and supervision of the
Board of Trustees of the Trust, of which the Fund is a series, to whom the
Adviser renders periodic reports of the Fund's investment activities.
 
  The advisory agreement will continue in effect from year to year if
specifically approved by the Trustees of the Trust, of which the Fund is a
separate series, (or by the Fund's shareholders) and by the disinterested
Trustees in compliance with the requirements of the 1940 Act. The agreement may
be terminated without penalty upon 60 days written notice by either party and
will automatically terminate in the event of assignment.
 
  The investment advisory agreement specifies that the Adviser will reimburse
each of the Funds for annual expenses of such Funds which exceed the most
stringent limit prescribed by any State in which the Fund's shares are offered
for sale. Currently, the most stringent limit in any State would require such
reimbursement to the extent that aggregate operating expenses of the Fund
(excluding interest, taxes and other expenses which may be excludable under
applicable state law) exceed in any fiscal year 2 1/2% of the average annual net
assets of the Fund up to $30 million, 2% of the average annual net assets of the
Fund of the next $70 million and 1 1/2% of the remaining average annual net
assets of the Fund. In addition to making any required reimbursements, the
Adviser may in its discretion, but is not obligated to, waive all or any portion
of its fee or assume all or any portion of the expenses of any of the Funds.
 
   
  For the years ended December 31, 1996, 1995 and 1994, the Fund paid advisory
expenses of $6,928,017, $5,813,647 and $5,028,401, respectively.
    
 
  OTHER AGREEMENTS.
 
   
  ACCOUNTING SERVICES AGREEMENT. The Fund has entered into an accounting
services agreement pursuant to which the Adviser provides accounting services
supplementary to those provided by the Custodian. Such services are expected to
enable the Fund to more closely monitor and maintain its accounts and records.
The Fund shares with the other Van Kampen American Capital funds in the cost of
providing such services, with 25% of such costs shared proportionately based on
the number of outstanding classes of securities per Fund and with the remaining
75 percent of such cost being paid by the Fund and such other Van Kampen
American Capital funds based proportionally on their respective net assets.
    
 
   
  For the years ended December 31, 1996, 1995 and 1994, the Fund paid expenses
of approximately $43,872, $42,800 and $31,650, respectively, representing the VK
Adviser's cost of providing accounting services.
    
 
   
  LEGAL SERVICES AGREEMENT. The Fund and each of the other Van Kampen American
Capital funds advised by the Adviser and distributed by the Distributor have
entered into Legal Services Agreements pursuant to which Van Kampen American
Capital provides legal services, including without limitation: accurate
maintenance of the funds' minute books and records, preparation and oversight of
the funds' regulatory reports, and other information provided to shareholders,
as well as responding to day-to-day legal issues on behalf of the funds. Payment
by the Fund for such services is made on a cost basis for the salary and salary
related benefits, including but not limited to bonuses, group insurances and
other regular wages for the employment of personnel, as well as overhead and the
expenses related to the office space and the equipment necessary to render the
legal services. Other funds distributed by the Distributor also receive legal
services from Van Kampen American Capital. Of the total costs for legal services
provided to funds distributed by the Distributor, one half of such costs are
allocated equally to each fund and the remaining one half of such costs are
allocated to specific funds based on monthly time records.
    
 
   
  For the years ended December 31, 1996, 1995 and 1994, the Fund paid expenses
of approximately $28,317, $39,400 and $25,100, respectively, representing Van
Kampen American Capital's cost of providing legal services.
    
 
   
                     CUSTODIAN AND INDEPENDENT ACCOUNTANTS
    
 
  State Street Bank and Trust Company, 225 Franklin Street, P.O. Box 1713,
Boston, MA 02105-1713, is the custodian of the Fund and has custody of all
securities and cash of the Fund. The custodian, among other
 
                                      B-31
<PAGE>   488
 
things, attends to the collection of principal and income, and payment for and
collection of proceeds of securities bought and sold by the Fund.
 
   
  The independent accountants for the Fund are KPMG Peat Marwick LLP, Chicago,
Illinois. The selection of independent accountants will be subject to
ratification by the shareholders of the Fund at any annual meeting of
shareholders.
    
 
                PORTFOLIO TRANSACTIONS AND BROKERAGE ALLOCATIONS
 
  The Adviser will place orders for portfolio transactions for the Fund with
broker-dealer firms giving consideration to the quality, quantity and nature of
each firms' professional services. These services include execution, clearance
procedures, wire service quotations and statistical and other research
information provided to the Fund and the investment adviser, including
quotations necessary to determine the value of the Fund's net assets. Any
research benefits derived are available for all clients of the investment
adviser. Since statistical and other research information is only supplementary
to the research efforts of the Adviser and still must be analyzed and reviewed
by its staff, the receipt of research information is not expected to materially
reduce its expenses.
 
  If it is believed to be in the best interests of the Fund, the Adviser may
place portfolio transactions with brokers who provide the types of research
service described above, even if it means the Fund will have to pay a higher
commission (or, if the broker's profit is part of the cost of the security, will
have to pay a higher price for the security) than would be the case if no weight
were given to the broker's furnishing of those research services. This will be
done, however, only if, in the opinion of the Adviser, the amount of additional
commission or increased cost is reasonable in relation to the value of such
services.
 
  In selecting among the firms believed to meet the criteria for handling a
particular transaction, the Adviser may take into consideration that certain
firms (i) provide market, statistical or other research information such as that
set forth above to the Fund and the Adviser, (ii) have sold or are selling
shares of the Fund and (iii) may select firms that are affiliated with the Fund,
its investment adviser or its distributor and other principal underwriters.
 
  If purchases or sales of securities of the Fund and of one or more other
investment companies or clients advised by the Adviser are considered at or
about the same time, transactions in such securities will be allocated among the
several investment companies and clients in a manner deemed equitable to all by
the Adviser, taking into account the respective sizes of the funds and the
amount of securities to be purchased or sold. Although it is possible that in
some cases this procedure could have a detrimental effect on the price or volume
of the security as far as the Fund is concerned, it is also possible that the
ability to participate in volume transactions and to negotiate lower brokerage
commissions will be beneficial to the Fund.
 
  While the Adviser will be primarily responsible for the placement of the
Fund's business, the policies and practices in this regard must be consistent
with the foregoing and will at all times be subject to review by the Trustees of
the Trust, of which the Fund is a separate series.
 
  The Trustees have adopted certain policies incorporating the standards of Rule
17e-1 issued by the Securities and Exchange Commission under the 1940 Act which
requires that the commission paid to the Distributor and other affiliates of the
Fund must be reasonable and fair compared to the commissions, fees or other
remuneration received or to be received by other brokers in connection with
comparable transactions involving similar securities during a comparable period
of time. The rule and procedures also contain review requirements and require
the Adviser to furnish reports to the Trustees and to maintain records in
connection with such reviews. After consideration of all factors deemed
relevant, the Trustees will consider from time to time whether the advisory fee
will be reduced by all or a portion of the brokerage commission given to brokers
that are affiliated with the Fund.
 
                             TAX STATUS OF THE FUND
 
   
  The Trust and any of its series, including the Fund, will be treated as
separate corporations for federal income tax purposes. The Fund intends to
qualify each year and to elect to be treated as a regulated
    
 
                                      B-32
<PAGE>   489
 
   
investment company under the Code. If the Fund so qualifies and distributes each
year to its shareholders at least 90% of its net investment income (including
tax-exempt interest, taxable income and net short-term capital gain, but not net
capital gains, which are the excess of long-term capital gains over net
short-term capital losses) in each year, it will not be required to pay federal
income taxes on any income distributed to shareholders. The Fund intends to
distribute at least the minimum amount of net investment income necessary to
satisfy the 90% distribution requirement. The Fund will not be subject to
federal income tax on any net capital gains distributed to shareholders.
    
 
                                THE DISTRIBUTOR
 
   
  The Distributor offers one of the industry's broadest lines of investments --
encompassing mutual funds, closed-end funds and unit investment trusts -- and is
currently the nation's 5th largest broker-sold mutual fund group according to
Strategic Insight, July 1995. VKAC manages or supervises more than $57 billion
in mutual funds, closed-end funds and unit investment trusts -- assets which
have been entrusted to VKAC in more than 2 million investor accounts. VKAC has
one of the largest research teams (outside of the rating agencies) in the
country, with more than 80 analysts devoted to various specializations. Each of
our high yield analysts, based either in San Francisco, Chicago, Houston or
Boston, has the responsibility to cover a specific region of the country. This
regional focus enables each high yield analyst to provide more specialized
coverage of the market and alert the portfolio manager to issues of local
importance.
    
 
   
  Shares of the Fund are offered on a continuous basis through the Distributor.
The Distributor is a wholly owned subsidiary of Van Kampen American Capital,
Inc., which is a subsidiary of VK/AC Holding, Inc., VK/AC Holding, Inc. is a
wholly-owned subsidiary of MSAM Holdings II, Inc. which, in turn, is a wholly-
owned subsidiary of Morgan Stanley Group Inc. The principal office of the Fund,
the Adviser, the Distributor and VKAC is located at One Parkview Plaza, Oakbrook
Terrace, Illinois 60181.
    
 
   
  Morgan Stanley Group Inc. and various of its directly or indirectly owned
subsidiaries, including Morgan Stanley & Co. Incorporated, a registered
broker-dealer and investment adviser, and Morgan Stanley International, are
engaged in a wide range of financial services. Their principal businesses
include securities underwriting, distribution and trading; merger, acquisition,
restructuring and other corporate finance advisory activities; merchant banking;
stock brokerage and research services; asset management; trading of futures,
options, foreign exchange, commodities and swaps (involving foreign exchange,
commodities, indices and interest rates); real estate advice, financing and
investing; and global custody, securities clearance services and securities
lending.
    
 
   
  On February 5, 1997, Morgan Stanley Group Inc. and Dean Witter, Discover & Co.
announced that they had entered into an Agreement and Plan of Merger to form
Morgan Stanley, Dean Witter, Discover & Co. Subject to certain conditions being
met, it is currently anticipated that the transaction will close in mid-1997.
Thereafter, Van Kampen American Capital Asset Management, Inc. will be an
indirect subsidiary of Morgan Stanley, Dean Witter, Discover & Co.
    
 
   
  Dean Witter, Discover & Co. is a financial services company with three major
businesses; full service brokerage, credit services and asset management.
    
 
   
  Pursuant to a distribution agreement, the Distributor will purchase shares of
the Fund for resale to the public, either directly or through securities
dealers, and is obligated to purchase only those shares for which it has
received purchase orders. A discussion of how to purchase and redeem the Fund's
shares and how the Fund's shares are priced is contained in the Prospectus.
    
 
   
                         DISTRIBUTION AND SERVICE PLANS
    
 
  The Fund has adopted a distribution plan (the "Distribution Plan") with
respect to each class of its shares pursuant to Rule 12b-1 under the 1940 Act.
The Fund also has adopted a service plan (the "Service Plan") with respect to
each class of its shares. The Distribution Plan and the Service Plan sometimes
are referred to herein collectively as the Plans. The Plans provide that the
Fund may spend a portion of the Fund's average
 
                                      B-33
<PAGE>   490
 
daily net assets attributable to each class of shares in connection with
distribution of the respective class of shares and in connection with the
provision of ongoing services to shareholders of such class, respectively. The
Plans are being implemented through an agreement (the "Distribution and Service
Agreement") with the Distributor and sub-agreements between the Distributor and
members of the NASD who are acting as securities dealers and NASD members or
eligible non-members who are acting as brokers or agents and similar agreements
between the Fund and financial intermediaries who are acting as brokers
(collectively, "Selling Agreements") that may provide for their customers or
clients certain services or assistance, which may include, but not be limited
to, processing purchase and redemption transactions, establishing and
maintaining shareholder accounts regarding the Fund, and such other services as
may be agreed to from time to time and as may be permitted by applicable
statute, rule or regulation. Brokers, dealers and financial intermediaries that
have entered into sub-agreements with the Distributor and sell shares of the
Fund are referred to herein as "financial intermediaries."
 
  Under the Distribution and Service Agreement and the Selling Agreements,
financial intermediaries that sold shares prior to July 1, 1987, or prior to the
beginning of the calendar quarter in which the Selling Agreement between the
Fund and such financial intermediary was approved by the Fund's Board of
Trustees (an "Implementation Date") are not eligible to receive compensation
pursuant to such Distribution and Service Agreement or Selling Agreement. To the
extent that there remain outstanding shares of the Fund that were purchased
prior to all Implementation Dates, the percentage of the total average daily net
asset value of a class of shares that may be utilized pursuant to the
Distribution and Service Agreement will be less than the maximum percentage
amount permissible with respect to such class of shares under the Distribution
and Service Agreement.
 
  The Distributor must submit quarterly reports to the Board of Trustees of the
Trust, of which the Fund is a series, setting forth separately by class of
shares all amounts paid under the Plans and the purposes for which such
expenditures were made, together with such other information as from time to
time is reasonably requested by the Trustees. The Plans provide that they will
continue in full force and effect from year to year so long as such continuance
is specifically approved by a vote of the Trustees, and also by a vote of the
disinterested Trustees, cast in person at a meeting called for the purpose of
voting on the Plans. Each of the Plans may not be amended to increase materially
the amount to be spent for the services described therein with respect to either
class of shares without approval by a vote of a majority of the outstanding
voting shares of such class, and all material amendments to either of the Plans
must be approved by the Trustees and also by the disinterested Trustees. Each of
the Plans may be terminated with respect to either class of shares at any time
by a vote of a majority of the disinterested Trustees or by a vote of a majority
of the outstanding voting shares of such class.
 
   
  For the fiscal year ended December 31, 1996, the Fund's aggregate expenses
under the Plans for Class A shares were $2,897,029 or 0.24% of the Class A
shares' average net assets. Such expenses were paid to reimburse the Distributor
for payments made to financial intermediaries for servicing Fund shareholders
and for administering the Plans. For the fiscal year ended December 31, 1996,
the Fund's aggregate expenses under the Plans for Class B shares were $721,697
or 1.00% of the Class B shares' average net assets. Such expenses were paid to
reimburse the Distributor for the following payments: $541,272 for commissions
and transaction fees paid to financial intermediaries in respect of sales of
Class B shares of the Fund and $180,425 for fees paid to financial
intermediaries for servicing Class B shareholders and administering the Plans.
For the fiscal year ended December 31, 1996, the Fund's aggregate expenses under
the Plans for Class C shares were $46,640 or 1.00% of the Class C shares'
average net assets. Such expenses were paid to reimburse the Distributor for the
following payments: $15,738 for commissions and transaction fees paid to
financial intermediaries in respect of sales of Class C shares of the Fund and
$30,902 for fees paid to financial intermediaries for servicing Class C
shareholders and administering the Plans.

                            PERFORMANCE INFORMATION
 
  From time to time marketing materials may provide a portfolio manager update,
an adviser update or discuss general economic conditions and outlooks. The
Fund's marketing materials may also show the Fund's asset class diversification,
top five sectors, ten largest holdings and other Fund asset structures, such as
duration, maturity, coupon, NAV, rating breakdown, AMT exposure and number of
issues in the portfolio. Materials may also mention how Van Kampen American
Capital believes the Fund compares relative to other Van Kampen American Capital
funds. Materials may also discuss the Dalbar Financial Services study from 1984
to 1994 which studied investor cash flow into and out of all types of mutual
funds. The ten year study found that investors who bought mutual fund shares and
held such shares outperformed investors who bought and sold. The Dalbar study
conclusions were consistent regardless of if shareholders purchased their funds
in direct or sales force distribution channels. The study showed that investors
working with a professional representative have tended over time to earn higher
returns than those who invested directly. The Fund will also be marketed on the
Internet.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
The Board of Trustees and Shareholders of
Van Kampen American Capital Insured Tax Free Income Fund:
 
We have audited the accompanying statement of assets and liabilities of Van
Kampen American Capital Insured Tax Free Income Fund (the "Fund"), including the
portfolio of investments, as of December 31, 1996, and the related statement of
operations for the year then ended, the statement of changes in net assets for
each of the two years in the period then ended, and the financial highlights for
each of the periods presented. These financial statements and financial
highlights are the responsibility of the Fund's management. Our responsibility
is to express an opinion on these financial statements and financial highlights
based on our audits.
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of
December 31, 1996, by correspondence with the custodian and brokers. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.
    In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of Van
Kampen American Capital Insured Tax Free Income Fund as of December 31, 1996,
the results of its operations for the year then ended, the changes in its net
assets for each of the two years in the period then ended, and the financial
highlights for each of the periods presented, in conformity with generally
accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
                               December 31, 1996
- --------------------------------------------------------------------------------
1. SIGNIFICANT ACCOUNTING POLICIES
Van Kampen American Capital Insured Tax Free Income Fund (the "Fund") is
organized as a series of Van Kampen American Capital Tax Free Trust (the
"Trust"), a Delaware business trust and is registered as a diversified open-end
management investment company under the Investment Company Act of 1940, as
amended. The Fund's investment objective is to provide investors with a high
level of current income exempt from federal income taxes, with liquidity and
safety of principal, primarily through an investment in a diversified portfolio
of insured municipal securities. The Fund commenced the distribution of its
Class B and Class C shares on May 1, 1993 and August 13, 1993, respectively. On
May 2, 1995, all Class D shareholders redeemed their shares and the class was
eliminated. The Fund will no longer offer Class D shares.
       The following is a summary of significant accounting policies
consistently followed by the Fund in the preparation of its financial
statements. The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
A. SECURITY VALUATION--Investments are stated at value using market quotations
or, if such valuations are not available, estimates obtained from yield data
relating to instruments or securities with similar characteristics in accordance
with procedures established in good faith by the Board of Trustees. Short-term
securities with remaining maturities of 60 days or less are valued at amortized
cost.
 
B. SECURITY TRANSACTIONS--Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis. The
Fund may purchase and sell securities on a "when issued" or "delayed delivery"
basis, with settlement to occur at a later date. The value of the security so
purchased is subject to market fluctuations during this period. The Fund will
maintain, in a segregated account with its custodian, assets having an aggregate
value at least equal to the amount of the when issued or delayed delivery
purchase commitments until payment is made.
 
C. INVESTMENT INCOME--Interest income is recorded on an accrual basis. Bond
premium and original issue discount are amortized over the expected life of each
applicable security.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
                               December 31, 1996
- --------------------------------------------------------------------------------
 
D. FEDERAL INCOME TAXES--It is the Fund's policy to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no provision for federal income taxes is required.

       Net realized losses differ for financial reporting and tax purposes as a
result of losses recognized for tax purposes on open futures positions at
December 31, 1996.
 
E. DISTRIBUTION OF INCOME AND GAINS--The Fund declares daily and pays monthly
dividends from net investment income. Net realized gains, if any, are
distributed annually. Distributions from net realized gains for book purposes
may include short-term capital gains, which are included as ordinary income for
tax purposes. For the year ended December 31, 1996, 99.8% of the income
distributions made by the Fund were exempt from federal income taxes.

       Due to inherent differences in the recognition of certain expenses under
generally accepted accounting principles and federal income tax purposes, the
amount of distributed net investment income may differ for a particular period.
These differences are temporary in nature, but may result in book basis
distribution in excess of net investment income for certain periods.

       Permanent book and tax basis differences relating to the recognition of
expenses associated with fund mergers (see Note 3) totaling $430,096 have been
reclassified from accumulated undistributed net investment income to capital.
 
F. INSURANCE EXPENSES--The Fund typically invests in insured bonds. Any
portfolio securities not specifically covered by a primary insurance policy are
insured secondarily through the Fund's portfolio insurance policy. Insurance
premiums are based on the daily balances of uninsured bonds in the portfolio of
investments and are charged to expense on an accrual basis. The insurance policy
guarantees the timely payment of principal and interest on the securities in the
Fund's portfolio.
 
2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

Under the terms of the Fund's Investment Advisory Agreement, Van Kampen American
Capital Investment Advisory Corp. (the "Adviser") will provide investment advice

                               December 31, 1996
- --------------------------------------------------------------------------------
 
       For the year ended December 31, 1996, VKAC, as Distributor for the Fund,
received commissions on sales of the Fund's Class A shares of approximately
$405,200 and CDSC on redeemed shares of approximately $233,200. Sales charges do
not represent expenses of the Fund.

       On September 27, 1995, the Fund acquired all of the assets and
liabilities of the Van Kampen American Capital Tax-Exempt Trust-Insured
Municipal Portfolio (the "AC Fund"), through a tax free reorganization approved
by AC Fund shareholders on September 21, 1995. The Fund issued 3,513,425 Class A
shares, 1,958,037 Class B shares and 73,421 Class C shares valued at
$65,701,115, $36,595,879 and $1,372,231, respectively, in exchange for AC Fund's
net assets. Shares issued in connection with this reorganization are included in
common share sales for the year ended December 31, 1995. Combined net assets on
the date of acquisition were $1,236,253,953.
 
4. INVESTMENT TRANSACTIONS

During the period, the cost of purchases and proceeds from sales of investments,
excluding short-term investments, were $1,258,779,404 and $1,320,020,635,
respectively.
 
5. DERIVATIVE FINANCIAL INSTRUMENTS

A derivative financial instrument in very general terms refers to a security
whose value is "derived" from the value of an underlying asset, reference rate
or index.

       The Fund has a variety of reasons to use derivative instruments, such as
to attempt to protect the Fund against possible changes in the market value of
its portfolio and to manage the portfolio's effective yield, maturity and
duration. All of the Fund's portfolio holdings, including derivative
instruments, are marked to market each day with the change in value reflected in
the unrealized appreciation/depreciation on securities. Upon disposition, a
realized gain or loss is recognized accordingly, except when exercising an
option contract or taking delivery of a security underlying a futures contract.
In these instances, the recognition of gain or loss is postponed until the
disposal of the security underlying the option or futures contract.

       Summarized below are the specific types of derivative financial
instruments used by the Fund.
 
A. OPTION CONTRACTS--An option contract gives the buyer the right, but not the
obligation to buy (call) or sell (put) an underlying item at a fixed exercise
price during a specified period. These contracts are generally used by the Fund
to manage the portfolio's effective maturity and duration.

       Transactions in options for the year ended December 31, 1996 were as
follows:

</TABLE>
 
B. FUTURES CONTRACTS--A futures contract is an agreement involving the delivery
of a particular asset on a specified future date at an agreed upon price. The
Fund generally invests in futures on U.S. Treasury Bonds and the Municipal Bond
Index and typically closes the contract prior to the delivery date. These
contracts are generally used to manage the portfolio's effective maturity and
duration.

- --------------------------------------------------------------------------------
 
       Upon entering into futures contracts, the Fund maintains, in a segregated
account with its custodian, securities with a value equal to its obligation
under the futures contracts. During the period the futures contract is open,
payments are received from or made to the broker based upon changes in the value
of the contract (the variation margin).

       Transactions in futures contracts for the year ended December 31, 1996,
were as follows:

</TABLE>
 
C. INDEXED SECURITIES--These instruments are identified in the portfolio of
investments. The price of these securities may be more volatile than the price
of a comparable fixed rate security.

       An Inverse Floating security is one where the coupon is inversely indexed
to a short-term floating interest rate multiplied by a specified factor. As the
floating rate rises, the coupon is reduced. Conversely, as the floating rate
declines, the coupon is increased. These instruments are typically used by the
Fund to enhance the yield of the portfolio.

       An Embedded Swap security includes a swap component such that the fixed
coupon component of the underlying bond is adjusted by the difference between
the securities fixed swap rate and the floating swap index. These instruments
are typically used by the Fund to enhance the yield of the portfolio.
 
6. DISTRIBUTION AND SERVICE PLANS

The Fund and its shareholders have adopted a distribution plan pursuant to Rule
12b-1 under the Investment Company Act of 1940 and a service plan (collectively
the "Plans"). The Plans govern payments for the distribution of the Fund's
shares, ongoing shareholder services and maintenance of shareholder accounts.

       Annual fees under the Plans of up to .25% of Class A net assets and 1.00%
each of Class B and Class C net assets are accrued daily. Included in these fees
for the year ended December 31, 1996, are payments to VKAC of approximately
$750,000.

Municipal Income Fund, Van Kampen American Capital Insured Tax Free Income Fund,
Van Kampen American Capital Intermediate Term Municipal Income Fund, Van Kampen
American Capital Florida Insured Tax Free Income Fund, Van Kampen American
Capital New Jersey Tax Free Income Fund and Van Kampen American Capital New York
Tax Free Income Fund have been organized as series of the Trust and have
commercial investment operations. Van Kampen American Capital California Tax
Free Income Fund, Van Kampen American Capital Michigan Tax Free Income Fund, Van
Kampen American Capital Missouri Tax Free Income Fund and Van Kampen American
Capital Ohio Tax Free Income Fund have been organized as series of the Trust but
have not commenced investment operations. Other series may be organized and
offered in the future. The Fund was originally organized under the name Van
Kampen Merritt California Insured Tax Free Fund as a sub-trust of Van Kampen
Merritt Tax Free Fund, a Massachusetts business trust. The Fund was reorganized
as a series of the Trust and adopted its present name as of July 31, 1995.
    
 
  Each share in a series of the Trust represents an equal proportionate interest
in the assets of such series with each other share in such series and no
interest in any other series. No series is subject to the liabilities of any
other series. The Declaration of Trust provides that shareholders are not liable
for any liabilities of the Trust or any of its series, requires inclusion of a
clause to that effect in every agreement entered into by the Trust or any of its
series and indemnifies shareholders against any such liability.
 
  Shares of the Trust entitle their holders to one vote per share; however,
separate votes are taken by each series on matters affecting an individual
series. For example, a change in investment policy for a series would be voted
upon by shareholders of only the series involved. Except as described in the
Prospectus, shares do not have cumulative voting rights, preemptive rights or
any conversion or exchange rights other than those described in the Prospectus.
The Trust does not contemplate holding regular meetings of shareholders to elect
Trustees or otherwise. However, the holders of 10% or more of the outstanding
shares may by written request require a meeting to consider the removal of
Trustees by a vote of two-thirds of the shares then outstanding cast in person
or by proxy at such meeting.
 
  The Trustees may amend the Declaration of Trust (including with respect to any
series) in any manner without shareholder approval, except that the Trustees may
not adopt any amendment adversely affecting the rights of shareholders of any
series without approval by a majority of the outstanding shares of each affected
series entitled to vote (or such higher vote as may be required by the
Investment Company Act of 1940, as amended (the "1940 Act") or other applicable
law).

                      INVESTMENT POLICIES AND RESTRICTIONS
 
  The investment objective of the Fund is set forth in the Prospectus under the
caption "Investment Objectives and Policies." There can be no assurance that the
Fund will achieve its objective.
 
  Fundamental investment restrictions limiting the investments of the Fund
provide that the Fund may not:
 
   1. Purchase any securities (other than tax exempt obligations guaranteed by
      the United States Government or by its agencies or instrumentalities), if
      as a result more than 5% of the Fund's total assets
 
                                       B-2
<PAGE>   518
 
   
      (taken at current value) would then be invested in securities of a single
      issuer or if as a result the Fund would hold more than 10% of the
      outstanding voting securities or any single issuer, except that up to 25%
      of the Fund's total assets may be invested without regard to such
      limitation, except that the Fund may purchase securities of other
      investment companies to the extent permitted by (i) the 1940 Act, as
      amended from time to time, (ii) the rules and regulations promulgated by
      the SEC under the 1940 Act, as amended from time to time, or (iii) an
      exemption or other relief from the provisions of the 1940 Act.
    
 
   
   2. Invest more than 25% of its assets in a single industry. (As described in
      the Prospectus, the Fund may from time to time invest more than 25% of its
      assets in a particular segment of the municipal bond market; however, the
      Fund will not invest more than 25% of its assets in industrial development
      bonds in a single industry), except that the Fund may purchase securities
      of other investment companies to the extent permitted by (i) the 1940 Act,
      as amended from time to time, (ii) the rules and regulations promulgated
      by the SEC under the 1940 Act, as amended from time to time, or (iii) an
      exemption or other relief from the provisions of the 1940 Act.
    
 
   3. Borrow money, except from banks for temporary purposes and then in amounts
      not in excess of 5% of the total asset value of the Fund, or mortgage,
      pledge or hypothecate any assets except in connection with a borrowing and
      in amounts not in excess of 10% of the total asset value of the Fund.
      Borrowings may not be made for investment leverage, but only to enable the
      Fund to satisfy redemption requests where liquidation of portfolio
      securities is considered disadvantageous or inconvenient. In this
      connection, the Fund will not purchase portfolio securities during any
      period that such borrowings exceed 5% of the total asset value of the
      Fund. Notwithstanding this investment restriction, the Fund may enter into
      "when issued" and "delayed delivery" transactions as described in the
      Prospectus.
 
   4. Make loans, except to the extent the tax exempt obligations the Fund may
      invest in are considered to be loans.
 
   5. Buy any securities "on margin." The deposit of initial or maintained
      margin in connection with interest rate or other financial futures or
      index contracts or related options is not considered the purchase of a
      security on margin.
 
   6. Sell any securities "short," write, purchase or sell puts, calls or
      combinations thereof, or purchase or sell interest rate or other financial
      futures or index contracts or related options, except as hedging
      transactions in accordance with the requirements of the Securities and
      Exchange Commission and the Commodity Futures Trading Commission.
 
   7. Act as an underwriter of securities, except to the extent the Fund may be
      deemed to be an underwriter in connection with the sale of securities held
      in its portfolio.
 
   
   8. Make investments for the purpose of exercising control or participation in
      management, except that the Fund may purchase securities of other
      investment companies to the extent permitted by (i) the 1940 Act, as
      amended from time to time, (ii) the rules and regulations promulgated by
      the SEC under the 1940 Act, as amended from time to time, or (iii) an
      exemption or other relief from the provisions of the 1940 Act.
    
 
   
   9. Invest in securities issued by other investment companies except as part
      of a merger, reorganization or other acquisition and extent permitted by
      (i) the 1940 Act, as amended from time to time, (ii) the rules and
      regulations promulgated by the SEC under the 1940 Act, as amended from
      time to time, or (iii) an exemption or other relief from the provisions of
      the 1940 Act.
    
 
  10. Invest in equity interests in oil, gas or other mineral exploration of
      development programs.
 
  11. Purchase or sell real estate commodities or commodity contracts, except as
      set forth in item 6 above and except to the extent the municipal
      securities in which the Fund may invest are considered to be interests in
      real estate.
 
  The Fund may not change any of these investment restrictions nor any other
fundamental policy as they apply to the Fund without the approval of the lesser
of (i) more than 50% of the Fund's outstanding shares or (ii) 67% of the Fund's
shares present at a meeting at which the holders of more than 50% of the
outstanding shares are present in person or by proxy. As long as the percentage
restrictions described above are satisfied at the time of the investment or
borrowing, the Fund will be considered to have abided by those restrictions even
 
                                       B-3
<PAGE>   519
 
if, at a later time, a change in values or net assets causes an increase or
decrease in percentage beyond that allowed.
 
  The Fund generally will not engage in the trading of securities for the
purpose of realizing short-term profits, but it will adjust its portfolio as
deemed advisable in view of prevailing or anticipated market conditions to
accomplish the Fund's investment objectives. For example, the Fund may sell
portfolio securities in anticipation of a movement in interest rates. Frequency
of portfolio turnover will not be a limiting factor if the Fund considers it
advantageous to purchase or sell securities. Portfolio turnover is calculated by
dividing the lesser of purchases or sales of portfolio securities by the monthly
average value of the securities in the portfolio during the year. Securities,
including options, whose maturity or expiration date at the time of acquisition
were one year or less are excluded from such calculation. The Fund anticipates
that its annual portfolio turnover rate will normally be less than 100%.
 
  The Fund does not intend to invest in certain "private activity" obligations
issued after August 7, 1986. Interest on such "private activity" obligations is
treated as a preference item for the purpose of calculating the alternative
minimum tax. If the Fund were to invest in such "private activity" obligations,
dividends paid to an investor who is subject to the alternative minimum tax
might not be completely tax exempt or might cause an investor to be subject to
such tax.
 
                      ADDITIONAL INVESTMENT CONSIDERATIONS
 
  MUNICIPAL SECURITIES. Municipal securities include long-term obligations,
which are often called municipal bonds, as well as shorter term municipal notes,
municipal leases, and tax-exempt commercial paper. Under normal market
conditions, longer term municipal securities generally provide a higher yield
than shorter term municipal securities, and therefore the Fund generally expects
to be invested primarily in longer term municipal securities. The Fund will,
however, invest in shorter term municipal securities when yields are greater
than yields available on longer term municipal securities, for temporary
defensive purposes and when redemption requests are expected. The two principal
classifications of municipal bonds are "general obligation" and "revenue" or
"special obligation" bonds, which include "industrial revenue bonds." General
obligation bonds are secured by the issuer's pledge of its faith, credit, and
taxing power for the payment of principal and interest. Revenue or special
obligation bonds are payable only from the revenues derived from a particular
facility or class of facilities or, in some cases, from the proceeds of a
special tax or other specific revenue source such as from the user of the
facility being financed.
 
  Also included within the general category of municipal securities are
participations in lease obligations or installment purchase contract obligations
(hereinafter collectively called "lease obligations") of municipal authorities
or entities used to finance the acquisition of equipment and facilities.
Although lease obligations do not constitute general obligations of the
municipality for which the municipality's taxing power is pledged a lease
obligation is ordinarily backed by the municipality's covenant to budget for,
appropriate and make the payments due under the lease obligation. However,
certain lease obligations contain "non-appropriation" clauses which provide that
the municipality has no obligation to make lease or installment purchase
payments in future years unless money is appropriated for such purpose on a
yearly basis. In addition to the "non-appropriation" risk, these securities
represent a relatively new type of financing that has not yet developed the
depth of marketability associated with more conventional bonds. Although
"non-appropriation" lease obligations are often secured by the underlying
property, disposition of the property in the event of foreclosure might prove
difficult. There is no limitation on the percentage of the Fund's assets that
may be invested in "non-appropriation" lease obligations. In evaluating such
lease obligations, the Adviser will consider such factors as it deems
appropriate, which factors may include (a) whether the lease can be cancelled,
(b) the ability of the lease obligee to direct the sale of the underlying
assets, (c) the general creditworthiness of the lease obligor, (d) the
likelihood that the municipality will discontinue appropriating funding for the
leased property in the event such property is no longer considered essential by
the municipality, (e) the legal recourse of the lease obligee in the event of
such a failure to appropriate funding and (f) any limitations which are imposed
on the lease obligor's ability to utilize substitute property or services than
those covered by the lease obligation.
 
                                       B-4
<PAGE>   520
 
  Also included in the term municipal securities are participation certificates
issued by state and local governments or authorities to finance the acquisition
of equipment and facilities. They may represent participations in a lease, an
installment purchase contract, or a conditional sales contract. Some municipal
leases and participation certificates may not be readily marketable.
 
  The "issuer" of municipal securities generally is deemed to be the
governmental agency, authority, instrumentality or other political subdivision,
or the non-governmental user of a revenue bond-financed facility, the assets and
revenues of which will be used to meet the payment obligations, or the guarantee
of such payment obligations, of the municipal securities.
 
  The Fund may purchase floating and variable rate demand notes, which are
municipal securities normally having a stated maturity in excess of one year,
but which permit the holder to demand payment of principal at any time, or at
specified intervals. The issuer of such notes normally has a corresponding
right, after a given period, to prepay at its discretion upon notice to the
noteholders the outstanding principal amount of the notes plus accrued interest.
The interest rate on a floating rate demand note is based on a known lending
rate, such as a bank's prime rate, and is adjusted automatically each time such
rate is adjusted. The interest rate on a variable rate demand note is adjusted
automatically at specified intervals.
 
  The Fund also may invest up to 15% of its total assets in derivative variable
rate municipal securities such as inverse floaters whose rates vary inversely
with changes in market rates of interest. Such derivative variable rate
municipal securities may pay a rate of interest determined by applying a
multiple to the variable rate. The extent of increases and decreases in the
value of derivative municipal securities whose rates vary inversely with changes
in market rates of interest in response to such changes in market rates
generally will be larger than comparable changes in the value of an equal
principal amount of a fixed rate municipal security having similar credit
quality, redemption provisions and maturity. In addition, the Fund may invest in
derivative municipal securities the terms of which include elements of, or are
similar in effect to, certain Strategic Transactions in which the Fund may
engage. Such municipal securities may by their terms, for example, have economic
characteristics comparable to, among other things, a swap, cap, floor or collar
transaction with respect to such security for a period of time prior to its
stated maturity. See "Additional Investment Considerations -- Strategic
Transactions" in this Statement of Additional Information.
 
  The Fund may also acquire custodial receipts or certificates underwritten by
securities dealers or banks that evidence ownership of future interest payments,
principal payments or both on certain municipal securities. The underwriter of
these certificates or receipts typically purchases municipal securities and
deposits the securities in an irrevocable trust or custodial account with a
custodian bank, which then issues receipts or certificates that evidence
ownership of the periodic unmatured coupon payments and the final principal
payment on the obligations. Although under the terms of a custodial receipt, the
Fund typically would be authorized to assert its rights directly against the
issuer of the underlying obligation, the Fund could be required to assert
through the custodian bank those rights as may exist against the underlying
issuer. Thus, in the event the underlying issuer fails to pay principal and/or
interest when due, the Fund may be subject to delays, expenses and risks that
are greater than those that would have been involved if the Fund had purchased a
direct obligation of the issuer. In addition, in the event that the trust or
custodial account in which the underlying security has been deposited is
determined to be an association taxable as a corporation, instead of a
non-taxable entity, the yield on the underlying security would be reduced in
recognition of any taxes paid.
 
  Although the municipal securities in which the Fund may invest will be insured
as to timely payment of principal and interest, municipal securities, like other
debt obligations, are subject to the risk of non-payment. The ability of issuers
of municipal securities to make timely payments of interest and principal may be
adversely impacted in general economic downturns and as relative governmental
cost burdens are allocated and reallocated among federal, state and local
governmental units. Such non-payment would result in a reduction of income to
the Fund, and could result in a reduction in the value of the municipal security
experiencing non-payment and a potential decrease in the net asset value of the
Fund. Issuers of municipal securities might seek protection under the bankruptcy
laws. In the event of bankruptcy of such an issuer, the Fund could experience
delays and limitations with respect to the collection of principal and interest
on such municipal securities and the Fund may not, in all circumstances, be able
to collect all principal and interest to which it is entitled. To enforce its
rights in the event of a default in the payment of interest or repayment of
 
                                       B-5
<PAGE>   521
 
principal, or both, the Fund may take possession of and manage the assets
securing the issuer's obligations on such securities, which may increase the
Fund's operating expenses and adversely affect the net asset value of the Fund.
Any income derived from the Fund's ownership or operation of such assets may not
be tax-exempt. In addition, the Fund's intention to qualify as a "regulated
investment company" under the Internal Revenue Code of 1986, as amended (the
"Code"), may limit the extent to which the Fund may exercise its rights by
taking possession of such assets, because as a regulated investment company the
Fund is subject to certain limitations on its investments and on the nature of
its income. See "Tax Status of the Fund."
 
  The Fund may invest up to 15% of its total assets in illiquid securities,
securities the disposition of which is subject to substantial legal or
contractual restrictions on resale and securities that are not readily
marketable. The sale of restricted and illiquid securities often requires more
time and results in higher brokerage charges or dealer discounts and other
selling expenses than does the sale of securities eligible for trading on
national securities exchanges or in the over-the-counter markets. Restricted
securities may sell at a price lower than similar securities that are not
subject to restrictions on resale. Restricted securities salable among qualified
institutional buyers without restriction pursuant to Rule 144A under the
Securities Act of 1933 that are determined to be liquid by the Adviser under
guidelines adopted by the Board of Trustees of the Trust (under which guidelines
the Adviser will consider factors such as trading activities and the
availability of price quotations), will not be treated as restricted securities
by the Fund pursuant to such rules. The Fund may, from time to time, adopt a
more restrictive limitation with respect to investment in illiquid and
restricted securities in order to comply with the most restrictive state
securities law, currently 10%. This policy does not include restricted
securities eligible for resale pursuant to Rule 144A under the Securities Act of
1933, as amended, which the Board of Trustees or the Fund's investment adviser
has determined under Board-approved guidelines to be liquid.
 
  SPECIAL CONSIDERATIONS RELATING TO CALIFORNIA MUNICIPAL SECURITIES. As
described in the Prospectus, except during temporary periods, the Fund will
invest substantially all of its assets in California municipal securities. The
portfolio of the Fund may include securities issued by the State of California
(the "State"), by its various public bodies (the "Agencies") and/or by other
municipal entities located within the State (securities of all such entities are
referred to herein as "California municipal securities").
 
  In addition, the specific California municipal securities in which the Fund
will invest will change from time to time. The Fund is therefore susceptible to
political, economic, regulatory or other factors affecting issuers of California
municipal securities. The following information constitutes only a brief summary
of a number of the complex factors which may impact issuers of California
municipal securities and does not purport to be a complete or exhaustive
description of all adverse conditions to which issuers of California municipal
securities may be subject. Such information is derived from official statements
utilized in connection with the issuance of California municipal securities, as
well as from other publicly available documents. Such information has not been
independently verified by the Fund and the Fund assumes no responsibility for
the completeness or accuracy of such information. Additionally, many factors,
including national, economic, social and environmental policies and conditions,
which are not within the control of such issuers, could have an adverse impact
on the financial condition of such issuers. The Fund cannot predict whether or
to what extent such factors or other factors may affect the issuers of
California municipal securities, the market value or marketability of such
securities or the ability of the respective issuers of such securities acquired
by the Fund to pay interest on or principal of such securities. The
creditworthiness of obligations issued by local California issuers may be
unrelated to the creditworthiness of obligations issued by the State of
California, and there is no assurance on the part of the State of California to
make payments on such local obligations. There may be specific factors that are
applicable in connection with investment in the obligations of particular
issuers located within California, and it is possible the Fund will invest in
obligations of particular issuers as to which such specific factors are
applicable. However, the information set forth below is intended only as a
general summary and not as a discussion of any specific factors that may affect
any particular issuer of California municipal securities.
 
  Constitutional Limits on Spending and Taxes. Certain California municipal
securities may be obligations of issuers which rely in whole or in part,
directly or indirectly, on ad valorem real property taxes as a source of
revenue. In 1978, California voters approved an amendment to the California
Constitution known as Proposition 13, the Jarvis/Gann Initiative, which added
Article XIIIA to the California Constitution. The effect of Article XIIIA is to
limit ad valorem taxes on real property and to restrict the ability of taxing
entities
 
                                       B-6
<PAGE>   522
 
to increase real property tax revenues. On June 18, 1992, the United States
Supreme Court upheld the constitutionality of Article XIIIA.
 
  In 1979, the voters of California passed an amendment adding Article XIIIB to
the California Constitution, the effect of which is to significantly limit
spending by State government and by "local government" (defined as "any city,
county, city and county, school district, special district, authority, or other
political subdivision of or within the state"). Excluded from these limitations
on government entities is "debt service" (defined as "appropriations required to
pay the cost of interest and redemption charges, including the funding of any
reserve or sinking fund required in connection therewith, on indebtedness
existing or legally authorized as of January 1, 1979 or on bonded indebtedness
thereafter approved" by the voters of the issuing entity).
 
  In November 1986, California voters approved an amendment to the California
Government Code known as Proposition 62 which added Article 3.7 to Title 5,
Division 2, Chapter 4 of the California Government Code. The effect of Article
3.7 is to limit the abilities of local governments to impose new taxes or
increase existing taxes by requiring certain legislative and voter approvals
prior to the imposition of certain taxes by any local government (defined as any
county, city, city and county, including a chartered city or county, or any
public or municipal corporation) or district (defined as any agency of the
state, formed pursuant to general law or special act, for the local performance
of governmental or proprietary functions within limited boundaries). Article 3.7
can be amended only by a vote of the electorate of the State of California. In
particular, Article 3.7, among other things, requires (i) two-thirds approval of
all members of the applicable legislative body followed by majority approval of
the voters voting in an election in order for a local government or district to
impose any general tax (defined as any tax imposed for general governmental
purposes), and (ii) two-thirds approval of the voters voting in an election in
order for a local government or district to impose any special tax (defined as
any tax imposed for a specific purpose). Those voting requirements do not apply
to ad valorem taxes to pay interest and redemption charges on any indebtedness
approved by the voters prior to the effective date of Article XIIIA of the
California Constitution. Article 3.7 requires (1) that the revenues from a
special tax be used only for the purpose or service for which the tax was
imposed, and (2) any tax subject to the measure imposed by any local government
or district on or after August 1, 1985 be ratified by majority vote of the
voters voting in an election held within two years after the effective date of
the measure in order for the tax to continue to be imposed on and after November
15, 1988. Article 3.7 contains a provision which diminishes the property tax
revenues allocated to a local government or district to the extent that the
local government or district imposed any tax not in compliance with Article 3.7.
Article 3.7 also provides that no local government or district may impose any ad
valorem tax on real property other than as permitted by Section 1 of Article
XIIIA of the California Constitution, and that no local government or district
may impose any transaction tax or sales tax on the sale of real property within
the city, county or district. A 1988 decision of the Fourth Appellate District
of the California Court of Appeals declared that the requirement of local voter
ratification provided for in Article 3.7 violated the California Constitution.
An initiative proposed to re-enact the ratification provisions of Article 3.7 as
a constitutional amendment was defeated by the voters in November 1990, but such
a proposal may be renewed in the future.
 
  On December 19, 1991, the California Supreme Court declared a 1988 San Diego
County Ballot measure that raised sales taxes for the purpose of financing
construction of criminal detention and courthouse facilities unconstitutional
because it was not passed with two-thirds voter approval. The court concluded
that the agency established to finance the facilities is a special district
created to circumvent Article XIIIA. However, in May 1992, the California
Supreme Court let stand two lower court decisions involving sales tax increases
passed by a majority vote. The lower courts had held that the Los Angeles County
Transportation Commission and the Orange County Transportation Authority, the
agencies entitled to collect the taxes, were not formed to circumvent Article
XIIIA, and that, therefore, the taxes were validly passed. On November 10, 1993,
in a closely watched case involving a Santa Clara County transportation
authority created with the parameters of the California Supreme Court's 1991
decision in mind, a California Court of Appeal overturned a sales tax approved
by less than two-thirds of the voters. In a September 1995 decision, the State
Supreme Court affirmed the Court of Appeal, declaring Proposition 62
constitutional under the California Constitution. The petitioners have filed for
a rehearing. The decision limited itself to cities organized by the State and
left unresolved whether Proposition 62 is constitutional as applied to cities
organized under a charter. Approximately half the population of the State
resides in charter cities. In March 1996, a Superior Court held that
 
                                       B-7
<PAGE>   523
 
charter cities do not have to submit taxes to voter approval despite the State
Supreme Court's Proposition 62 ruling . These decisions may continue to cast
doubt on other projects around the State that have been financed with sales tax
increases imposed without two-thirds voter approval. Soon after the State
Supreme Court decision, Moody's Investors Services, Inc. indicated that the
ruling has broad negative implications on the ability of the State's cities and
counties to raise revenue and issue debt supported by general fund revenues.
 
   
  On November 5, 1996, voters approved Proposition 218, entitled the "Right to
Vote on Taxes Act," which incorporates new Articles XIIIC and XIIID into the
California Constitution. These new provisions enact limitations on the ability
of local government agencies to impose or raise various taxes, fees, charges and
assessments without voter approval. Certain "general taxes" imposed after
January 1, 1995 must be approved by voters in order to remain in effect. In
addition, Article XIIIC clarifies the right of local voters to reduce taxes,
fees, assessments or charges through local initiatives.
    
 
   
  Proposition 218 does not affect the State or its ability to levy or collect
taxes. There are a number of ambiguities concerning the Proposition and its
impact on local governments and their bonded debt which will require
interpretation by the courts or the Legislature. The Legislative Analyst
estimated that enactment of Proposition 218 would reduce local government
revenues statewide by over $100 million a year, and that over time revenues to
local government would be reduced by several hundred million dollars a year
under this Proposition.
    
 
   
  Because of the complex nature of Articles XIIIA-D, the ambiguities and
possible inconsistencies in their respective terms, and the applicability of
their respective exemptions and exceptions and the impossibility of predicting
future appropriations, it is not presently possible to determine the impact of
Article XIIIA-D or any implementing or related legislation on the California
municipal securities in which the Fund may invest, or the abilities of State or
local governments to pay the interest on, or repay the principal of such
California municipal securities.
    
 
   
  Proposition 98. On November 8, 1988, voters approved Proposition 98, a
combined initiative constitutional amendment and statute called the "Classroom
Instructional Improvement and Accountability Act" (the "Act"). The Act changes
State funding of public education below the university level and the operation
of the State's Appropriations Limit. The Act, as amended, guarantees State
funding for K-12 school districts and community college districts at a level
equal to the greater of (a) in general, a fixed percentage of General Fund
revenues, (b) the amount actually appropriated to such districts from the
General Fund in the previous fiscal year, adjusted for either changes in the
cost of living, or (c) a third test which would replace the test in (b) if the
percentage growth in per capita of General Fund revenues in the prior year plus
one half of one percent is less than the percentage growth in California per
capita personal income. Under the test in (c), the schools would receive the
amount appropriated in the prior year adjusted for changes in enrollment and
General Fund revenues. The Act permits the legislature, by two-thirds vote of
both houses, with the Governor's concurrence, to suspend this formula for a
one-year period. The Act could cause increasing pressure on the State's budget
over future years, potentially reducing resources available for other State
programs, especially to the extent the Article XIIIB spending limit would
restrain the State's ability to fund such other programs by raising taxes. The
Act also changes how tax revenues in excess of the State's Appropriations Limit
are distributed. Any excess State tax revenues up to a specified amount would,
instead of being returned to taxpayers, be transferred to K-12 school and
community college districts. Such transfer would be excluded from the
Appropriations Limit for K-14 school districts, and the K-14 school
Appropriations Limits for the next year would be automatically increased by the
amount of such transfer. These additional moneys would enter the base funding
calculation for K-14 schools for subsequent years, creating further pressure on
other portions of the state budget, particularly if revenues decline in a year
following such a transfer.
    
 
   
  Local Governments. The fiscal condition of local governments has been
constrained since the enactment of "Prospectus 13" in 1978, which reduced and
limited the future growth of property taxes, and limited the ability of local
government to impose "special taxes" (those devoted to a specific purpose)
without two-thirds voter approval.
    
 
   
  Counties, in particular, have had fewer options to raise revenues than many
other local government entities, and have been required to maintain many
services. The entire statewide welfare system will be changed in
    
 
                                       B-8

response to the change in federal welfare law enacted in 1996. It is yet not
known how the final system will affect county finances. Under current law,
counties are required to provide "general assistance" aid to certain persons who
cannot obtain welfare from other programs, but this mandate may be eliminated as
part of the overhaul.
    
 
   
  In the aftermath of Proposition 13, the State provided aid from the General
Fund to make up some of the loss of property tax moneys, including taking over
the principal responsibility for funding local K-12 schools and community
colleges. Under the pressure of the recent recession, the Legislature has
eliminated the remnants of this post-Proposition 13 aid to entities other than
K-14 education districts, although it has also provided additional funding
sources (such as sales taxes) and reduced mandates for local services. Many
counties continue to be under severe fiscal stress. While such stress has in
recent years most often been experienced by smaller, rural counties, larger
urban counties, such as Los Angeles, have also been affected.
    
 
   
  In November of 1994, Standard & Poor's Rating Group downgraded the credit
rating of several California counties, including San Francisco, San Diego,
Marin, Los Angeles and San Bernadino. In December of 1994 and January of 1995,
Standard & Poor's Rating Group and Moody's Investors Services, Inc.,
respectively, downgraded Orange County to below investment grade as a result of
its bankruptcy filing (see discussion below). In August of 1995, Standard &
Poor's Rating Group again downgraded the credit rating of Los Angeles County and
placed it on CreditWatch. Moody's Investors Services, Inc. also downgraded Los
Angeles County. In October of 1995, Standard & Poor's Rating Group placed San
Diego County's $449.3 million in general fund-supported debt issues on
CreditWatch. Since the passage of Proposition 218 in November 1997, five of the
seven California cities reviewed by the major rating agencies have been
downgraded (Los Angeles, Sacramento, San Diego, Fresno and Anaheim).
    
 
   
  On December 6, 1994, Orange County, California (the "County"), together with
its pooled investment funds (the "Funds") filed for protection under Chapter 9
of the federal Bankruptcy Code, after reports that the Funds had suffered
significant market losses in their investments, causing a liquidity crisis for
the Funds and the County. More than 200 other public entities, most of which,
but not all, are located in the County, were also depositors in the Funds. As of
mid-January, 1995, following a restructuring of most of the Funds' assets to
increase their liquidity and reduce their exposure to interest rate increases,
the County estimated the Funds' loss at about $1.69 billion, or 23% of their
initial deposits of approximately $7.5 billion. Many of the entities which
deposited moneys in the Funds, including the County, are facing cash flow
difficulties because of the bankruptcy filing and may be required to reduce
programs or capital projects. This may also affect their ability to meet their
outstanding obligations. In June, 1996, Orange County emerged from bankruptcy
protection as part of a fiscal recovery plan that included the issuance of new
recovery bonds and sharp reductions in services and personnel. Moody's gave the
insured recovery bonds an underlying rating of Baa and the county's general
obligation bonds a Ba rating. Standard & Poor's gave the recovery bonds a B
underlying rating and Fitch Investors Service assigned the bonds as underlying
rating of BBB.
    
 
   
  State Finances. From 1990 until 1994 the State experienced the worst economic
fiscal, and budget conditions since the 1930's. Construction, manufacturing
(especially aerospace), and financial services, among others, have all been
severely affected. Job losses were the worst of any post-war recession.
    
 
  The recession seriously affected State tax revenues, which basically mirror
economic conditions. It also caused increased expenditures for health and
welfare programs. The State has also been facing a structural imbalance in its
budget with the largest programs supported by the General Fund -- K-14
education, health, welfare and corrections -- growing at rates significantly
higher than the growth rates for the principal revenue sources of the General
Fund. As a result, the State entered a period of chronic budget imbalance.
 
  A further consequence of the large budget imbalances in the 1990-91 and
1991-92 fiscal years was that the State used up all of its available cash
resources. In late June, 1992, the State was required to issue $475 million of
short-term revenue anticipation warrants to cover General Fund obligations
coming due on June 30. These warrants were repaid on July 24, 1992. With the
failure of the Governor and Legislature to adopt a budget for the 1992-93 fiscal
year on time (to allow the State to carry out its usual cash flow borrowing for
the fiscal year), the shortfall of cash forced the State Controller after July
1, 1992 to issue interest-bearing "registered warrants" in lieu of regular
warrants redeemable for cash to many State vendors, suppliers, and employees and
to local government agencies. Until the State budget was adopted on September 2,
1992, the
 
                                       B-9
<PAGE>   525
 
   
Controller issued registered warrants totaling approximately $3.8 billion to pay
valid obligations from the prior fiscal year, and to pay continuing obligations
after July 1 based on special appropriations or court orders. Certain
constitutionally mandated obligations, such as debt service on bonds and revenue
anticipation warrants, were paid with available cash. Registered warrants had
not been issued by the State since the 1930s. State employees successfully sued
the State alleging that payment of their salaries with registered warrants
violated federal labor laws.
    
 
   
  As a result of the deterioration in the State's budget and cash situation
since the 1991-92 fiscal year, rating agencies reduced the State's credit
rating. Between October 1991 and October 1992, the rating on the general
obligation bonds was reduced by Standard & Poor's Ratings Group from "AAA" to
"A+", by Moody's Investors Services, Inc. from "Aaa" to "Aa" and by Fitch
Investors Services, Inc. from "AAA" to "AA". On July 15, 1994, all three of the
rating agencies rating the State's long-term debt again lowered their ratings of
the State's general obligation bonds. Moody's Investors Services, Inc. lowered
its rating from "Aa" to "A1", Standard & Poor's Ratings Group lowered its rating
from "A+" to "A", and Fitch Investors Service lowered its rating from "AA" to
"A". In July 1996, Standard & Poor's raised its rating to A+ from A. Fitch
Investors Service also rated its rating last year to A+ from A. There can be no
assurance that such ratings will continue for any given period of time or that
they will not in the future be further revised or withdrawn. It should be noted
that the creditworthiness of obligations issued by local California issuers may
be unrelated to the creditworthiness of obligations issued by the State of
California, and there is no obligation on the part of the State to make payment
on such obligations in the event of default.
    
 
   
  The 1996-97 Budget Act was signed by the Governor on July 15, 1996, along with
various implementing bills. The Governor vetoed about $82 million of
appropriations (both General Fund and Special Fund). With the signing of the
Budget Act, the State implemented its regular cash flow borrowing program with
the issuance of $3.0 billion of Revenue Anticipation Notes to mature on June 30,
1997. The Budget Act appropriated a modest budget reserve in the Special Fund
for Economic Uncertainties of $305 million, as of June 30, 1997. The Department
of Finance projected that, on June 30, 1997, the State's available internal
borrowable (cash) resources will be $2.9 billion, after payment of all
obligations due by that date, so that no cross-fiscal year borrowing will be
needed.
    
 
   
  With the continued strong economic recovery in the State, the Department of
Finance has estimated, in connection with the release of the Governor's 1997-98
Budget Proposal, that revenues for the 1996-97 Fiscal Year will exceed initial
projections by about $760 million. This increase will be offset by higher
expenditures for K-14 school aid (pursuant to Proposition 98) and for health and
welfare costs, because federal law changes and other federal actions did not
provide as much assistance to the State as was initially planned in the Budget
Act. The Department's updated projections show a balance in the Special Fund for
Economic Uncertainties of $197 million, slightly lower than projected in July,
1996. The Department also projects the State's cash position will be stronger
than originally estimated, with unused internal borrowable resources at June 30,
1997 of about $4.3 billion.
    
 
   
  On January 9, 1997, the Governor released his proposed budget for the 1997-98
Fiscal Year (the "Governor's Budget"). The Governor's Budget projects General
Fund revenues and transfers in 1997-98 of $50.7 billion, a 4.6% increase from
revised 1996-97 figures. The Governor proposes expenditures of $50.3 billion, a
3.9% increase from 1996-97. The Governor's Budget projects a balance in the
Special Fund for Economic Uncertainties of $553 million on June 30, 1998. The
Governor's Budget also anticipates about $3 billion of external borrowing for
cash flow purposes during the year, with no requirements for cross-fiscal year
borrowing.
    
 
  It is not presently possible (1) to know whether, and to what extent, the
State General Fund or any Special Funds will have surplus or deficit balances in
the 1995-1996 fiscal year or in any subsequent fiscal year, or (2) to determine
the overall impact of any deficits on future allocations of the State revenues
to local governments or on the abilities of State or local governments to pay
the interest on, or repay the principal of, any California municipal securities
in which the Fund may invest.
 
   
  Litigation. At any given time, including the present, there are numerous civil
actions pending against the State (including, but not limited to, those
discussed in the preceding paragraphs and below), which could, if
    
 
                                      B-10
<PAGE>   526
 
determined adversely to the State, affect the State's expenditures and, in some
cases, its revenues. The following are certain of the more significant lawsuits
pending against the State.
 
   
  The State is involved in a lawsuit. Thomas Hayes v. Commission on State
Mandates, related to state-mandated costs. The action involves an appeal by the
Director of Finance from a 1984 decision by the State Board of Control (now
succeeded by the Commission on State Mandates (Commission)). The Board of
Control decided in favor of local school districts' claims for reimbursement for
special education programs for handicapped students. The case was then brought
to the trial court by the State and later remanded to the Commission for
redetermination. The Commission has since expanded the claim to include
supplemental claims filed by seven other educational institutions; the issuance
of a final consolidated decision is anticipated sometime in early 1997. To date,
the Legislature has not appropriated funds. The liability to the State, if all
potentially eligible school districts pursue timely claims, has been estimated
by the Department of Finance at more than $1 billion.
    
 
   
  The State is involved in a lawsuit related to contamination at the
Stringfellow toxic waste site. In United States, People of the State of
California v. J. B. Stringfellow, Jr., et al., the State is seeking recovery for
past costs of cleanup of the site, a declaration that the defendants are jointly
and severally liable for future costs, and an injunction ordering completion of
the cleanup. However, the defendants have filed a counterclaim against the State
for alleged negligent acts. Because the State is the present owner of the site,
the State may be found liable. Present estimates of the cleanup range from $200
million to $800 million.
    
 
   
  The State is a defendant in a coordinated action involving 3,000 plaintiffs
seeking recovery for damages caused by the Yuba River flood of February 1986.
The trial court has found liability in inverse condemnation and awarded damages
of $500,000 to a sample of plaintiffs. The State's potential liability to the
remaining plaintiffs ranges from $800 million to $1.5 billion. An appeal has
been filed.
    
 
   
  The State is a defendant in California State Employees Association v. Wilson,
where the petitioners are challenging several budget appropriations in the 1994
and 1995 Budget Acts. The appropriations mandate the transfer of funds from the
State Highway Account to the General Fund to reimburse the General Fund for debt
service costs on two rail bond measures. The petitioners contend that the
transfers violate the bond acts themselves and are requesting the monies be
returned. The loss to the State's General Fund could be up to $227 million.
    
 
   
  In a similar case, Professional Engineers in California Government v. Wilson,
the petitioners are challenging several appropriations in the 1993, 1994, and
1995 Budget Acts. The appropriations mandate the transfer of approximately $262
million from the State Highway Account and $113 million from the Motor Vehicle
Account to the General Fund and appropriate approximately $6 million from the
State Highway Account to fund a highway-grade crossing program administered by
the Public Utilities Commission. Petitioners contend that the transfers violate
several constitutional provisions and request that the moneys be returned to the
State Highway Account and Motor Vehicle Account.
    
 
   
  The State is a defendant in Just Say No To Tobacco Dough Campaign v. State of
California, where the petitioners challenge the appropriation of approximately
$186 million of Proposition 99 funds in the Cigarette and Tobacco Products
Surtax Fund for years ended June 30, 1990, through June 30, 1995 for programs
which were allegedly not health education or tobacco-related disease research.
If the State loses, the General Fund and funds from other sources would be used
to reimburse the Cigarette and Tobacco Products Surtax Fund for approximately
$186 million.
    
 
   
  The State is a defendant in the case of Kurt Hathaway, et al. v. Wilson, et
al., where the plaintiffs are challenging the legality of various budget action
transfers and appropriations from particular special funds for years ended June
30, 1995, and June 30, 1996. The plaintiffs allege that the transfers and
appropriations are contrary to the substantive law establishing the funds and
providing for interest accruals to the fund, violate the single subject
requirement of the State Commission, and is an invalid "special law." Plaintiffs
seek to have monies totaling approximately $355 million returned to the special
funds.
    
 
   
  The State is a defendant in two related cases, Beno vs. Sullivan (Beno) and
Welch vs. Anderson (Welch), concerning reductions in Aid to Families with
Dependent Children (AFDC) grant payments. In the Beno case, plaintiffs seek to
invalidate AFDC grant reductions and in the Welch case, plaintiffs contend that
AFDC
    
 
                                      B-11
<PAGE>   527
 
   
grant reductions are not authorized by state law. The Beno case concerns the
total grant reductions while the Welch case concerns the period of time the
State did not have a waiver for those reductions. The State's potential
liability for retroactive AFDC grant reductions is estimated at $831 million if
the plaintiffs are awarded the full amount in both cases.
    
 
   
  In the case of Board of Administration, California Public Employees'
Retirement System, et al. v. Pete Wilson, Governor, et al., plaintiffs
challenged the constitutionality of legislation which deferred payment of the
State's employer contribution to the Public Employees' Retirement System
beginning in Fiscal Year 1992-93. On January 11, 1995, the Sacramento County
Superior Court entered a judgment finding that the legislation
unconstitutionally impaired the vested contract rights of PERS members. The
judgment provides for issuance of a writ of mandate directing State defendants
to disregard the provisions of the legislation, to implement the statute
governing employer contributions that existed before the changes in the
legislation found to be unconstitutional, and to transfer to PERS the 1993-94
and 1994-95 contributions that are unpaid to date. The State defendants have
appealed. A hearing before the State Court of Appeal took place in January 1997.
    
 
   
  Recent Legislation. Recently, legislation has been enacted which (1)
increases, in limited instances, the abilities of both county boards of
supervisors and redevelopment agencies to impose new special taxes; (2) repeals
the existing limitations on the amount of notes of the State of California which
may be sold; (3) eliminates certain restrictions on repayment of general
obligations bonds; (4) allows revenue anticipation notes to be repaid in a
succeeding fiscal year and generally facilitates their issuance; (5) increases
the ability of community redevelopment agencies to issue revenue bonds for the
purpose of refunding bonds of other political subdivisions of the State; (6) cut
corporate tax rates by 5% a year; and (7) automatically and proportionately
reduces programmed General Fund appropriations for the next fiscal year (except
those mandated by the Constitution) up to 4%, if the State Director of Finance,
with concurrence of the Commission on State Finance, certifies that revenues for
such fiscal year were not expected to meet programmed budgetary requirements.
    
 
  Additional legislation has been or may be introduced which would create new
regional agencies with the ability to tax and issue debt, alter the definition
of ownership changes that trigger reassessment of business property under
Article XIIIA, modify existing taxes or other revenue-raising measures or which
either would further limit or, alternatively would increase the abilities of
State and local governments to impose new taxes, increase existing taxes
(including sales tax increases to fund earthquake relief), or issue bonds or
other debt instruments. It is not currently possible to predict the extent to
which any such legislation will be enacted. Furthermore, other measures
affecting the taxing or spending authority of California or its political
subdivisions may be approved or enacted in the future. Nor is it currently
possible to determine the impact of any recently enacted or proposed legislation
on California municipal securities in which the Fund may invest or future
allocations of State revenues to local governments.
 
  INVESTMENT PRACTICES.  If the Adviser deems it appropriate to seek to hedge
the Fund's portfolio against market value changes, the Fund may buy or sell
derivative instruments such as financial futures contracts and related options,
such as municipal bond index futures contracts and the related put or call
options contracts on such index futures. A tax exempt bond index fluctuates with
changes in the market values of the tax exempt bonds included in the index. An
index future is an agreement pursuant to which two parties agree to receive or
deliver at settlement an amount of cash equal to a specified dollar amount
multiplied by the difference between the value of the index at the close of the
last trading day of the contract and the price at which the future was
originally written. A financial future is an agreement between two parties to
buy and sell a security for a set price on a future date. An index future has
similar characteristics to a financial future except that settlement is made
through delivery of cash rather than the underlying securities. An example is
the Long-Term Municipal Bond futures contract traded on the Chicago Board of
Trade. It is based on the Bond Buyer's Municipal Bond Index, which represents an
adjusted average price of the forty most recent long-term municipal issues of
$50 million or more ($75 million in the instance of housing issues) rated A or
better by either Moody's Investors Service, Inc. ("Moody's") or Standard &
Poor's Ratings Group ("S&P"), maturing in no less than nineteen years, having a
first call in no less than seven nor more than sixteen years, and callable at
par.
 
                                      B-12
<PAGE>   528
 
  The Fund may engage in "when issued" and "delayed delivery" transactions and
utilize futures contracts and options thereon for hedging purposes. The
Securities and Exchange Commission ("SEC") generally requires that when mutual
funds, such as the Fund, effect transactions of the foregoing nature, such funds
must either segregate cash or readily marketable portfolio securities with its
custodian in an amount of its obligations under the foregoing transactions, or
cover such obligations by maintaining positions in portfolio securities, futures
contracts or options that would serve to satisfy or offset the risk of such
obligations. When effecting transactions of the foregoing nature, the Fund will
comply with such segregation or cover requirements.
 
  STRATEGIC TRANSACTIONS. The Fund may, but is not required to, utilize various
other investment strategies as described below to hedge various market risks
(such as interest rates and broad or specific market movements) or to manage the
effective maturity or duration of the Fund's fixed-income securities. Such
strategies are generally accepted by modern portfolio managers and are regularly
utilized by many mutual funds and other institutional investors. Techniques and
instruments may change over time as new instruments and strategies are developed
or regulatory changes occur.
 
  In the course of pursuing these investment strategies, the Fund may purchase
and sell derivative instruments such as exchange-listed and over-the-counter put
and call options on securities, fixed-income indices and other financial
instruments, purchase and sell financial futures contracts and options thereon,
enter into various interest rate transactions such as swaps, caps, floors or
collars (collectively, all the above are called "Strategic Transactions").
Strategic Transactions may be used to attempt to protect against possible
changes in the market value of securities held in or to be purchased for the
Fund's portfolio resulting from securities markets fluctuations, to protect the
Fund's unrealized gains in the value of its portfolio securities, to facilitate
the sale of such securities for investment purposes, to manage the effective
maturity or duration of the Fund's portfolio, or to establish a position in the
derivatives markets as a temporary substitute for purchasing or selling
particular securities.
 
  Any or all of these investment techniques may be used at any time and there is
no particular strategy that dictates the use of one technique rather than
another, as use of any Strategic Transaction is a function of numerous variables
including market conditions. The ability of the Fund to utilize these Strategic
Transactions successfully will depend on the Adviser's ability to predict
pertinent market movements, which cannot be assured. The Fund will comply with
applicable regulatory requirements when implementing these strategies,
techniques and instruments. Strategic Transactions involving financial futures
and options thereon will be purchased, sold or entered into only for bona fide
hedging, risk management or portfolio management purposes and not for
speculative purposes.
 
  Strategic Transactions have risks associated with them including possible
default by the other party to the transaction, illiquidity and, to the extent
the Adviser's view as to certain market movements is incorrect, the risk that
the use of such Strategic Transactions could result in losses greater than if
they had not been used. Use of put and call options may result in losses to the
Fund, force the sale or purchase of portfolio securities at inopportune times or
for prices other than current market values, limit the amount of appreciation
the Fund can realize on its investments or cause the Fund to hold a security it
might otherwise sell. The use of options and futures transactions entails
certain other risks. In particular, the variable degree of correlation between
price movements of futures contracts and price movements in the related
portfolio position of the Fund creates the possibility that losses on the
hedging instrument may be greater than gains in the value of the Fund's
position. In addition, futures and options markets may not be liquid in all
circumstances and certain over-the-counter options may have no markets. As a
result, in certain markets, the Fund might not be able to close out a
transaction without incurring substantial losses, if at all. Although the use of
futures and options transactions for hedging should tend to minimize the risk of
loss due to a decline in the value of the hedged position, at the same time they
tend to limit any potential gain which might result from an increase in value of
such position. Finally, the daily variation margin requirements for futures
contracts would create a greater ongoing potential financial risk than would
purchases of options, where the exposure is limited to the cost of the initial
premium. Losses resulting from the use of Strategic Transactions would reduce
net asset value, and possibly income, and such losses can be greater than if the
Strategic Transactions had not been utilized. Income earned or deemed to be
earned, if any, by the Fund from its Strategic Transactions will generally be
taxable income of the Fund. See "Tax Status" in the Prospectus.

  GENERAL CHARACTERISTICS OF OPTIONS.   Put options and call options typically
have similar structural characteristics and operational mechanics regardless of
the underlying instrument on which they are purchased or sold. Thus, the
following general discussion relates to each of the particular types of options
discussed in greater detail below. In addition, many Strategic Transactions
involving options require segregation of Fund assets in special accounts, as
described below under "Use of Segregated and Other Special Accounts."
 
  A put option gives the purchaser of the option, upon payment of a premium, the
right to sell, and the writer the obligation to buy, the underlying security,
commodity, index, or other instrument at the exercise price. For instance, the
Fund's purchase of a put option on a security might be designed to protect its
holdings in the underlying instrument (or, in some cases, a similar instrument)
against a substantial decline in the market value by giving the Fund the right
to sell such instrument at the option exercise price. A call option, upon
payment of a premium, gives the purchaser of the option the right to buy, and
the seller the obligation to sell, the underlying instrument at the exercise
price. The Fund's purchase of a call option on a security, financial future,
index, or other instrument might be intended to protect the Fund against an
increase in the price of the underlying instrument that it intends to purchase
in the future by fixing the price at which it may purchase such instrument. An
American style put or call option may be exercised at any time during the option
period while a European style put or call option may be exercised only upon
expiration or during a fixed period prior thereto. The Fund is authorized to
purchase and sell exchange listed options and over-the-counter options ("OTC
options"). Exchange listed options are issued by a regulated intermediary such
as the Options Clearing Corporation ("OCC"), which guarantees the performance of
the obligations of the parties to such options. The discussion below uses the
OCC as a paradigm, but is also applicable to other financial intermediaries.
 
  With certain exceptions, OCC issued and exchange listed options generally
settle by physical delivery of the underlying security or currency, although in
the future cash settlement may become available. Index options and Eurodollar
instruments are cash settled for the net amount, if any, by which the option is
"in-the-money" (i.e., where the value of the underlying instrument exceeds, in
the case of a call option, or is less than, in the case of a put option, the
exercise price of the option) at the time the option is exercised. Frequently,
rather than taking or making delivery of the underlying instrument through the
process of exercising the option, listed options are closed by entering into
offsetting purchase or sale transactions that do not result in ownership of the
new option.
 
  The Fund's ability to close out its position as a purchaser or seller of an
OCC or exchange listed put or call option is dependent, in part, upon the
liquidity of the option market. Among the possible reasons for the absence of a
liquid option 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 including
reaching daily price limits; (iv) interruption of the normal operations of the
OCC or an exchange; (v) inadequacy of the facilities of an exchange or 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 relevant market for that option on that exchange would cease
to exist, although outstanding options on that exchange would generally continue
to be exercisable in accordance with their terms.
 
  The hours of trading for listed options may not coincide with the hours during
which the underlying financial instruments are traded. To the extent that the
option markets close before the markets for the underlying financial
instruments, significant price and rate movements can take place in the
underlying markets that cannot be reflected in the option markets.
 
  OTC options are purchased from or sold to securities dealers, financial
institutions or other parties ("Counterparties") through direct bilateral
agreement with the Counterparty. In contrast to exchange listed options, which
generally have standardized terms and performance mechanics, all the terms of an
OTC option, including such terms as method of settlement, term, exercise price,
premium, guarantees and security, are set by negotiation of the parties. The
Fund will only sell OTC options that are subject to a buy-back provision
permitting the Fund to require the Counterparty to sell the option back to the
Fund at a formula price within
 
                                      B-14
<PAGE>   530
 
seven days. The Fund expects generally to enter into OTC options that have cash
settlement provisions, although it is not required to do so.
 
  Unless the parties provide for it, there is no central clearing or guaranty
function in an OTC option. As a result, if the Counterparty fails to make or
take delivery of the security, or other instrument underlying an OTC option it
has entered into with the Fund or fails to make a cash settlement payment due in
accordance with the terms of that option, the Fund will lose any premium it paid
for the option as well as any anticipated benefit of the transaction.
Accordingly, the Adviser must assess the creditworthiness of each such
Counterparty or any guarantor or credit enhancement of the Counterparty's credit
to determine the likelihood that the terms of the OTC option will be satisfied.
The Fund will engage in OTC option transactions only with United States
government securities dealers recognized by the Federal Reserve Bank of New York
as "primary dealers", or broker dealers, domestic or foreign banks or other
financial institutions which have received (or the guarantors of the obligation
of which have received) a short-term credit rating of "A-1" from S&P or "P-1"
from Moody's or an equivalent rating from any other nationally recognized
statistical rating organization ("NRSRO"). The staff of the SEC currently takes
the position that, in general, OTC options on securities other than U.S.
Government securities purchased by the Fund, and portfolio securities "covering"
the amount of the Fund's obligation pursuant to an OTC option sold by it (the
cost of the sell-back plus the in-the-money amount, if any) are illiquid, and
are subject to the Fund's limitation on investing no more than 15% of its assets
in illiquid securities.
 
  If the Fund sells a call option, the premium that it receives may serve as a
partial hedge, to the extent of the option premium, against a decrease in the
value of the underlying securities or instruments in its portfolio or will
increase the Fund's income. The sale of put options can also provide income.
 
  The Fund may purchase and sell call options on securities, including U.S.
Treasury and agency securities, municipal obligations, mortgage-backed
securities and Eurodollar instruments that are traded on U.S. and foreign
securities exchanges and in the over-the-counter markets. All calls sold by the
Fund must be "covered" (i.e., the Fund must own the securities or futures
contract subject to the call) or must meet the asset segregation requirements
described below as long as the call is outstanding. Even though the Fund will
receive the option premium to help protect it against loss, a call sold by the
Fund exposes the Fund during the term of the option to possible loss of
opportunity to realize appreciation in the market price of the underlying
security or instrument and may require the Fund to hold a security or instrument
which it might otherwise have sold.
 
  The Fund may purchase and sell put options on securities including U.S.
Treasury and agency securities, mortgage-backed securities, municipal
obligations and Eurodollar instruments (whether or not it holds the above
securities in its portfolio.) The Fund will not sell put options if, as a
result, more than 50% of the Fund's assets would be required to be segregated to
cover its potential obligations under such put options other than those with
respect to futures and options thereon. In selling put options, there is a risk
that the Fund may be required to buy the underlying security at a
disadvantageous price above the market price.
 
  GENERAL CHARACTERISTICS OF FUTURES.  The Fund may enter into financial futures
contracts or purchase or sell put and call options on such futures as a hedge
against anticipated interest rate or fixed-income market changes, for duration
management and for risk management purposes. Futures are generally bought and
sold on the commodities exchanges where they are listed with payment of initial
and variation margin as described below. The purchase of a futures contract
creates a firm obligation by the Fund, as purchaser, to take delivery from the
seller the specific type of financial instrument called for in the contract at a
specific future time for a specified price (or, with respect to index futures
and Eurodollar instruments, the net cash amount). The sale of a futures contract
creates a firm obligation by the Fund, as seller, to deliver to the buyer the
specific type of financial instrument called for in the contract at a specific
future time for a specified price (or, with respect to index futures and
Eurodollar instruments, the net cash amount). Options on futures contracts are
similar to options on securities except that 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 and obligates the seller to deliver such option.
 
  The Fund's use of financial futures and options thereon will in all cases be
consistent with applicable regulatory requirements and in particular the rules
and regulations of the Commodity Futures Trading Commission and will be entered
into only for bona fide hedging, risk management (including duration
 
                                      B-15
<PAGE>   531
 
management) or other portfolio management purposes. Typically, maintaining a
futures contract or selling an option thereon requires the Fund to deposit with
a financial intermediary as security for its obligations an amount of cash or
other specified assets (initial margin) which initially is typically 1% to 10%
of the face amount of the contract (but may be higher in some circumstances).
Additional cash or assets (variation margin) may be required to be deposited
thereafter on a daily basis as the mark to market value of the contract
fluctuates. The purchase of options on financial futures involves payment of a
premium for the option without any further obligation on the part of the Fund.
If the Fund exercises an option on a futures contract it will be obligated to
post initial margin (and potential subsequent variation margin) for the
resulting futures position just as it would for any position. Futures contracts
and options thereon are generally settled by entering into an offsetting
transaction but there can be no assurance that the position can be offset prior
to settlement at an advantageous price nor that delivery will occur.
 
  The Fund will not enter into a futures contract or related option (except for
closing transactions) if, immediately thereafter, the sum of the amount of its
initial margin and premiums on open futures contracts and options thereon would
exceed 5% of the Fund's total assets (taken at current value); however, in the
case of an option that is in-the-money at the time of the purchase, the
in-the-money amount may be excluded in calculating the 5% limitation. The
segregation requirements with respect to futures contracts and options thereon
are described below.
 
  OPTIONS ON SECURITIES INDICES AND OTHER FINANCIAL INDICES.  The Fund also may
purchase and sell call and put options on securities indices and other financial
indices and in so doing can achieve many of the same objectives it would achieve
through the sale or purchase of options on individual securities or other
instruments. Options on securities indices and other financial indices are
similar to options on a security or other instrument except that, rather than
settling by physical delivery of the underlying instrument, they settle by cash
settlement, i.e., an option on an index gives the holder the right to receive,
upon exercise of the option, an amount of cash if the closing level of the index
upon which the option is based exceeds, in the case of a call, or is less than,
in the case of a put, the exercise price of the option (except if, in the case
of an OTC option, physical delivery is specified). This amount of cash is equal
to the excess of the closing price of the index over the exercise price of the
option, which also may be multiplied by a formula value. The seller of the
option is obligated, in return for the premium received, to make delivery of
this amount. The gain or loss on an option on an index depends on price
movements in the instruments making up the market, market segment, industry or
other composite on which the underlying index is based, rather than price
movements in individual securities, as is the case with respect to options on
securities.
 
  COMBINED TRANSACTIONS.  The Fund may enter into multiple transactions,
including multiple options transactions, multiple futures transactions and
multiple interest rate transactions and any combination of futures, options and
interest rate transactions ("component" transactions), instead of a single
Strategic Transaction, as part of a single or combined strategy when, in the
opinion of the Adviser, it is in the best interests of the Fund to do so. A
combined transaction will usually contain elements of risk that are present in
each of its component transactions. Although combined transactions are normally
entered into based on the Adviser's judgment that the combined strategies will
reduce risk or otherwise more effectively achieve the desired portfolio
management goal, it is possible that the combination will instead increase such
risks or hinder achievement of the portfolio management objective.
 
  SWAPS, CAPS, FLOORS AND COLLARS.  Among the Strategic Transactions into which
the Fund may enter are interest rate and index swaps and the purchase or sale of
related caps, floors and collars. The Fund expects to enter into these
transactions primarily to preserve a return or spread on a particular investment
or portion of its portfolio, as a duration management technique or to protect
against any increase in the price of securities the Fund anticipates purchasing
at a later date. The Fund intends to use these transactions as hedges and not as
speculative investments and will not sell interest rate caps or floors where it
does not own securities or other instruments providing the income stream the
Fund may be obligated to pay. Interest rate swaps involve the exchange by the
Fund with another party of their respective commitments to pay or receive
interest, e.g., an exchange of floating rate payments for fixed rate payments
with respect to a notional amount of principal. An index swap is an agreement to
swap cash flows on a notional amount based on changes in the values of the
reference indices. The purchase of a cap entitles the purchaser to receive
payments on a notional principal amount from the party selling such cap to the
extent that a specified index exceeds a predetermined interest
 
                                      B-16
<PAGE>   532
 
rate or amount. The purchase of a floor entitles the purchaser to receive
payments on a notional principal amount from the party selling such floor to the
extent that a specified index falls below a predetermined interest rate or
amount. A collar is a combination of a cap and a floor that preserves a certain
return within a predetermined range of interest rates or values.
 
  The Fund will usually enter into swaps on a net basis, i.e., the two payment
streams are netted out in a cash settlement on the payment date or dates
specified in the instrument, with the Fund receiving or paying, as the case may
be, only the net amount of the two payments. Inasmuch as these swaps, caps,
floors and collars are entered into for good faith hedging purposes, the Adviser
and the Fund believe such obligations do not constitute senior securities under
the 1940 Act and, accordingly, will not treat them as being subject to its
borrowing restrictions. The Fund will not enter into any swap, cap, floor or
collar transaction unless, at the time of entering into such transaction, the
unsecured long-term debt of the Counterparty, combined with any credit
enhancements, is rated at least "A" by S&P or Moody's or has an equivalent
equity rating from an NRSRO or is determined to be of equivalent credit quality
by the Adviser. If there is a default by the Counterparty, the Fund may have
contractual remedies pursuant to the agreements related to the transaction. The
swap market has grown substantially in recent years with a large number of banks
and investment banking firms acting both as principals and agents utilizing
standardized swap documentation. As a result, the swap market has become
relatively liquid. Caps, floors and collars are more recent innovations for
which standardized documentation has not yet been fully developed and,
accordingly, they are less liquid than swaps.
 
   
  USE OF SEGREGATED AND OTHER SPECIAL ACCOUNTS.  Many Strategic Transactions, in
addition to other requirements, require that the Fund segregate liquid
high-grade assets with its custodian to the extent Fund obligations are not
otherwise "covered" through ownership of the underlying security, financial
instrument or currency. In general, either the full amount of any obligation by
the Fund to pay or deliver securities or assets must be covered at all times by
the securities, instruments or currency required to be delivered, or, subject to
any regulatory restrictions, an amount of cash or liquid securities at least
equal to the current amount of the obligation must be segregated with the
custodian. The segregated assets cannot be sold or transferred unless equivalent
assets are substituted in their place or it is no longer necessary to segregate
them. For example, a call option written by the Fund will require the Fund to
hold the securities subject to the call (or securities convertible into the
needed securities without additional consideration) or to segregate liquid
securities sufficient to purchase and deliver the securities if the call is
exercised. A call option sold by the Fund on an index will require the Fund to
own portfolio securities which correlate with the index or to segregate liquid
securities equal to the excess of the index value over the exercise price on a
current basis. A put option written by the Fund requires the Fund to segregate
liquid securities equal to the exercise price.
    
 
  OTC options entered into by the Fund, including those on securities, financial
instruments or indices and OCC issued and exchange listed index options, will
generally provide for cash settlement. As a result, when the Fund sells these
instruments it will only segregate an amount of assets equal to its accrued net
obligations, as there is no requirement for payment or delivery of amounts in
excess of the net amount. These amounts will equal 100% of the exercise price in
the case of a non cash-settled put, the same as an OCC guaranteed listed option
sold by the Fund, or the in-the-money amount plus any sell-back formula amount
in the case of a cash-settled put or call. In addition, when the Fund sells a
call option on an index at a time when the in-the-money amount exceeds the
exercise price, the Fund will segregate, until the option expires or is closed
out, cash or cash equivalents equal in value to such excess. OCC issued and
exchange listed options sold by the Fund other than those above generally settle
with physical delivery, and the Fund will segregate an amount of assets equal to
the full value of the option. OTC options settling with physical delivery, or
with an election of either physical delivery or cash settlement, will be treated
the same as other options settling with physical delivery.
 
  In the case of a futures contract or an option thereon, the Fund must deposit
initial margin and possible daily variation margin in addition to segregating
assets sufficient to meet its obligation to purchase or provide securities or
currencies, or to pay the amount owed at the expiration of an index- based
futures contract. Such assets may consist of cash, cash equivalents, liquid debt
or equity securities or other acceptable assets.
 
   
  With respect to swaps, the Fund will accrue the net amount of the excess, if
any, of its obligations over its entitlements with respect to each swap on a
daily basis and will segregate an amount of cash or securities
    
 
                                      B-17
<PAGE>   533
 
having a value equal to the accrued excess. Caps, floors and collars require
segregation of assets with a value equal to the Fund's net obligation, if any.
 
  Strategic Transactions may be covered by other means when consistent with
applicable regulatory policies. The Fund may also enter into offsetting
transactions so that its combined position, coupled with any segregated assets,
equals its net outstanding obligation in related options and Strategic
Transactions. For example, the Fund could purchase a put option if the strike
price of that option is the same or higher than the strike price of a put option
sold by the Fund. Moreover, instead of segregating assets if the Fund held a
futures or forward contract, it could purchase a put option on the same futures
or forward contract with a strike price as high or higher than the price of the
contract held. Other Strategic Transactions may also be offset in combinations.
If the offsetting transaction terminates at the time of or after the primary
transaction no segregation is required, but if it terminates prior to such time,
assets equal to any remaining obligation would need to be segregated.
 
  The Fund's activities involving Strategic Transactions may be limited by the
requirements of Subchapter M of the Code for qualification as a regulated
investment company. See "Tax Status" in the Prospectus.
 
  INSURANCE.  As described in the Prospectus, the Fund will generally invest
only in municipal securities which are either pre-insured under a policy
obtained for such securities prior to the purchase of such securities or will be
insured under policies obtained by the Fund to cover otherwise uninsured
securities.
 
  Original Issue Insurance.  Original Issue Insurance is purchased with respect
to a particular issue of municipal securities by the issuer thereof or a third
party in conjunction with the original issuance of such municipal securities.
Under such insurance, the insurer unconditionally guarantees to the holder of
the insured municipal security the timely payment of principal and interest on
such obligation when and as such payments shall become due but shall not be paid
by the issuer, except that in the event of any acceleration of the due date of
the principal by reason of mandatory or optional redemption (other than
acceleration by reason of a mandatory sinking fund payment), default or
otherwise, the payments insured may be made in such amounts and at such times as
payments of principal would have been due had there not been such acceleration.
The insurer is responsible for such payments less any amounts received by the
holder from any trustee for the municipal security issuers or from any other
source. Original Issue Insurance generally does not insure payment on an
accelerated basis, the payment of any redemption premium (except with respect to
certain premium payments in the case of certain small issue industrial
development and pollution control municipal securities), the value of the Shares
of the Fund or the market value of municipal securities, or payments of any
tender purchase price upon the tender of the municipal securities. Original
Issue Insurance also does not insure against nonpayment of principal of or
interest on municipal securities resulting from the insolvency, negligence or
any other act or omission of the trustee or other paying agent for such
obligations.
 
  In the event that interest on or principal of a municipal security covered by
insurance is due for payment but is unpaid by reason of nonpayment by the issuer
thereof, the applicable insurer will make payments to its fiscal agent (the
"Fiscal Agent") equal to such unpaid amounts of principal and interest not later
than one business day after the insurer has been notified that such nonpayment
has occurred (but not earlier than the date such payment is due). The Fiscal
Agent will disburse to the Fund the amount of principal and interest which is
then due for payment but is unpaid upon receipt by the Fiscal Agent of (i)
evidence of the Fund's right to receive payment of such principal and interest
and (ii) evidence, including any appropriate instruments of assignment, that all
of the rights of payment of such principal or interest then due for payment
shall thereupon vest in the insurer. Upon payment by the insurer of any
principal or interest payments with respect to any municipal securities, the
insurer shall succeed to the rights of the Fund with respects to such payment.
 
  Original Issue Insurance remains in effect as long as the municipal securities
covered thereby remain outstanding and the insurer remains in business,
regardless of whether the Fund ultimately disposes of such municipal securities.
Consequently, Original Issue Insurance may be considered to represent an element
of market value with respect to the municipal securities so insured, but the
exact effect, if any, of this insurance on such market value cannot be
estimated.
 
  Secondary Market Insurance.  Subsequent to the time of original issuance of a
municipal security, the Fund or a third party may, upon the payment of a single
premium, purchase insurance on such municipal
 
                                      B-18
<PAGE>   534
 
security. Secondary Market Insurance generally provides the same type of
coverage as is provided by Original Issue Insurance and, as is the case with
Original Issue Insurance, Secondary Market Insurance remains in effect as long
as the municipal securities covered thereby remain outstanding and the insurer
remains in business, regardless of whether the Fund ultimately disposes of such
municipal securities. All premiums respecting municipal securities covered by
Original Issue Insurance or Secondary Market Insurance are paid in advance by
the issuer or other party obtaining the insurance.
 
  One of the purposes of acquiring Secondary Market Insurance with respect to a
particular municipal security would be to enable the Fund to enhance the value
of such municipal security. The Fund, for example, might seek to purchase a
particular municipal security and obtain Secondary Market Insurance with respect
thereto if, in the opinion of the Adviser, the market value of such municipal
security, as insured, would exceed the current value of the municipal security
without insurance plus the cost of the Secondary Market Insurance. Similarly, if
the Fund owns but wishes to sell a municipal security that is then covered by
Portfolio Insurance, the Fund might seek to obtain Secondary Market Insurance
with respect thereto if, in the opinion of the Adviser, the net proceeds of a
sale by the Fund of such obligation, as insured, would exceed the current value
of such obligation plus the cost of the Secondary Market Insurance.
 
  Portfolio Insurance.  The Portfolio Insurance policies obtained by the Fund
would insure the payment of principal and interest on specified eligible
municipal securities purchased by the Fund. Except as described below, Portfolio
Insurance generally provides the same type of coverage as is provided by
Original Issue Insurance or Secondary Market Insurance. Municipal securities
insured under one Portfolio Insurance policy generally would not be insured
under any other policy purchased by the Fund. A municipal security is eligible
for coverage under a policy if it meets certain requirements of the insurer.
Portfolio Insurance is intended to reduce financial risk, but the cost thereof
and compliance with investment restrictions imposed under the policy will reduce
the yield to shareholders of the Fund. If a municipal security already is
covered by Original Issue Insurance of Secondary Market Insurance, the Fund is
not required to additionally insure any such municipal security under any policy
of Portfolio Insurance that the Fund may purchase.
 
  Portfolio Insurance policies are effective only as to municipal securities
owned and held by the Fund, and do not cover municipal securities for which the
contract for purchase fails. A "when-issued" municipal security will be covered
under a Portfolio Insurance policy upon the settlement date of the issue of such
"when-issued" municipal security.
 
  In determining whether to insure municipal securities held by the Fund, an
insurer will apply its own standards, which correspond generally to the
standards it has established for determining the insurability of new issues of
municipal securities. See "Original Issue Insurance" above.
 
  Each Portfolio Insurance policy will be non-cancellable and will remain in
effect so long as the Fund is in existence, the municipal securities covered by
the policy continue to be held by the Fund, and the Fund pays the premiums for
the policy. Each insurer generally will reserve the right at any time upon 90
days written notice to the Fund to refuse to insure any additional securities
purchased by the Fund after the effective date of such notice. The Board of
Trustees of the Fund generally will reserve the right to terminate each policy
upon seven days written notice to an insurer if it determines that the cost of
such policy is not reasonable in relation to the value of the insurance to the
Fund.
 
  Each Portfolio Insurance policy shall terminate as to any municipal security
that has been redeemed from or sold by the Fund on the date of such redemption
or the settlement date of such sale, and an insurer shall not have any liability
thereafter under a policy as to any such municipal security, except that if the
date of such redemption or the settlement date of such sale occurs after a
record date and before the related payment date with respect to any such
municipal security, the policy will terminate as to such municipal security on
the business day immediately following such payment date. Each policy will
terminate as to all municipal securities covered thereby on the date on which
the last of the covered municipal securities mature, are redeemed or are sold by
the Fund.
 
  One or more policies of Portfolio Insurance may provide the Fund, pursuant to
an irrevocable commitment of the insurer, with the option to exercise the right
to obtain permanent insurance ("Permanent Insurance")
 
                                      B-19
<PAGE>   535
 
with respect to a municipal security that is to be sold by the Fund. The Fund
would exercise the right to obtain Permanent Insurance upon payment of a single,
predetermined insurance premium payable from the proceeds of the sale of such
municipal security. It is expected that the Fund will exercise the right to
obtain Permanent Insurance for a municipal security only if, in the opinion of
the Adviser, upon such exercise the net proceeds from the sale by the Fund of
such obligation, as insured, would exceed the proceeds from the sale of such
obligation without insurance. The Permanent Insurance premium with respect to
each such obligation is determined based upon the insurability of each such
obligation as of the date of purchase by the Fund and will not be increased or
decreased for any change in the creditworthiness of such obligation unless such
obligation is in default as to payment of principal or interest, or both. In
such event, the Permanent Insurance premium shall be subject to an increase
predetermined at the date of purchase by the Fund.
 
  Because each Portfolio Insurance policy will terminate as to municipal
securities sold by the Fund on the date of sale, in which event the insurer will
be liable only for those payments of principal and interest that are then due
and owing (unless Permanent Insurance is obtained by the Fund), the provision
for this insurance will not enhance the marketability of securities held by the
Fund, whether or not the securities are in default or in significant risk of
default. On the other hand, since Original Issue Insurance and Secondary Market
Insurance will remain in effect as long as municipal securities covered thereby
are outstanding, such insurance may enhance the marketability of such securities
even when such securities are in default or in significant risk of default, but
the exact effect, if any, on the marketability cannot be estimated. Accordingly,
the Fund may determine to retain or, alternatively, to sell municipal securities
covered by Original Issue Insurance or Secondary Market Insurance that are in
default or in significant risk of default.
 
  It is anticipated that certain of the municipal securities to be purchased by
the Fund will be insured under policies obtained by persons other than the Fund.
In instances in which the Fund purchases municipal securities insured under
policies obtained by persons other than the Fund, the Fund does not pay the
premiums for such policies; rather the cost of such policies may be reflected in
a higher purchase price for such municipal securities. Accordingly, the yield on
such municipal securities may be lower than that on similar uninsured municipal
securities. Premiums for a Portfolio Insurance Policy generally are paid by the
Fund monthly, and are adjusted for purchases and sales of municipal securities
covered by the policy during the month. The yield on the Fund's portfolio is
reduced to the extent of the insurance premiums paid by the Fund which, in turn,
will depend upon the characteristics of the covered municipal securities held by
the Fund. In the event the Fund were to purchase Secondary Market Insurance with
respect to any municipal securities then covered by a Portfolio Insurance
policy, the coverage and the obligation of the Fund to pay monthly premiums
under such policy would cease with such purchase.
 
  There can be no assurance that insurance of the kind described above will
continue to be available to the Fund. In the event that such insurance is no
longer available or that the cost of such insurance outweighs the benefits to
the Fund in the view of the Board of Trustees, the Board will consider whether
to modify the investment policies of the Fund, which may require the approval of
shareholders. In the event the claims-paying ability rating of an insurer of
municipal securities in the Fund's portfolio were to be lowered from AAA by S&P,
or if the Adviser anticipates such a lowering or otherwise does not believe an
insurer's claims-paying ability merits its existing triple-A rating, the Fund
could seek to obtain additional insurance from an insurer whose claims-paying
ability is rated AAA by S&P, or if the Adviser determines that the cost of
obtaining such additional insurance outweigh the benefits, the Fund may elect
not to obtain additional insurance. In making such determination, the Adviser
will consider the cost of the additional insurance, the new claims-paying
ability rating and financial condition of the existing insurer and the
creditworthiness of the issuer and/or guarantor of the underlying municipal
securities. The Adviser also may determine not to purchase additional insurance
in such circumstances if it believes that the insurer is taking steps which will
cause its triple-A claims paying ability rating to be restored promptly.
 
  Although the Adviser periodically reviews the financial condition of each
insurer, there can be no assurance that the insurers will be able to honour
their obligations under all circumstances. In that regard, it should be noted
that the claims-paying abilities and debt ratings of several large insurers (at
least one of which insured municipal securities) recently have been lowered by
one or more of the nationally recognized securities rating agencies and that
many insurers currently are experiencing adverse results in their investment
portfolios. In
 
                                      B-20
<PAGE>   536
 
addition, certain insurers' operations recently have been assumed by their state
regulatory agencies. The Fund cannot predict the consequences of a state
takeover of an insurer's obligations and, in particular, whether such an insurer
(or its state regulatory agency) could or would honour all of the insurer's
contractual obligations including any outstanding insurance contracts insuring
the timely payment of principal and interest on municipal securities. The Fund
cannot predict the impact which such events might have on the market values of
such municipal security. In the event of a default by an insurer on its
obligations with respect to any municipal securities in the Fund's portfolio,
the Fund would look to the issuer and/or guarantor of the relevant municipal
securities for payments of principal and interest and such issuer and/or
guarantor may not be rated AAA by S&P. Accordingly, the Fund could be exposed to
greater risk of non-payment in such circumstances which could adversely affect
the Fund's net asset value and the market price per Common Share. Alternatively,
the Fund could elect to dispose of such municipal securities; however, the
market prices for such municipal securities may be lower than the Fund's
purchase price for them and the Fund could sustain a capital loss as a result.
 
  Although the insurance on municipal securities reduces financial or credit
risk in respect of the insured obligations (i.e., the possibility that owners of
the insured municipal securities will not receive timely scheduled payments of
principal or interest), insured municipal securities remain subject to market
risk (i.e., fluctuations in market value as a result of changes in prevailing
interest rates). Accordingly, insurance on municipal securities does not insure
the market value of the Fund's assets or the net asset value or the market price
for the Common Shares.
 
  AMBAC Indemnity Corporation.  AMBAC Indemnity is a Wisconsin-domiciled stock
insurance corporation regulated by the Insurance Department of the State of
Wisconsin and licensed to do business in 50 states and the District of Columbia.
On December 31, 1991, AMBAC Indemnity had admitted assets of approximately
$1,431,000,000, total liabilities of approximately $684,400,000 and statutory
capital of approximately $830,000,000. Statutory capital consists of AMBAC
Indemnity's policyholders' surplus and statutory contingency reserve. AMBAC
Indemnity was formerly a wholly-owned subsidiary of Citicorp Financial Guaranty
Holdings, Inc. ("Holdings") (formerly known as AMBAC Inc.), a financial holding
company and itself a wholly-owned subsidiary of Citibank, N.A. ("Citibank").
According to Best Insurance Report (1991 edition), AMBAC Indemnity's aggregate
exposure under all Class I (municipal bond insurance) financial guaranty bonds,
the only class set forth therein, in force as of December 31, 1990 was
$86,200,000,000.
 
  On May 1, 1991, AMBAC Inc. ("AMBAC Inc."), a financial holding company formed
by Holdings, registered for sale with the Securities and Exchange Commission
17,600,000 shares of its common stock. The registration statement with respect
to such sale was declared effective on July 11, 1991. As a result of the sale,
Citibank, through its affiliate Holdings, owns approximately 49% of the total
equity of AMBAC Inc., with a right to cast 20% of the total number of votes of
all shares of outstanding common stock of AMBAC Inc. until such time as
Citibank, including its affiliates, reduces its equity ownership to less than
25% of AMBAC Inc. (at which time the shares owned by it become non-voting). As
of the date of the consummation of the sale of common stock, AMBAC Indemnity
became a direct wholly owned subsidiary of AMBAC Inc. The Wisconsin Insurance
Department has stated that the sale of common stock described herein does not
require its prior approval. Both Moody's and S&P have reaffirmed that the sale
of the common stock of AMBAC Inc. does not affect AMBAC Indemnity's triple-A
claims-paying ability ratings.
 
  AMBAC Indemnity has entered into pro rata reinsurance agreements under which a
percentage of the insurance underwritten pursuant to certain municipal bond
insurance programs of AMBAC Indemnity has been and will be assumed by a number
of foreign and domestic unaffiliated reinsurers.
 
  Copies of AMBAC Indemnity's financial statements prepared in accordance with
statutory accounting standards are available from AMBAC Indemnity. The address
of AMBAC Indemnity's administrative offices and its telephone number are One
State Street Plaza, 17th Floor, New York, New York 10004 and (212) 668-0340.

                  DESCRIPTION OF MUNICIPAL SECURITIES RATINGS
 
  STANDARD & POOR'S RATINGS GROUP--A brief description of the applicable
Standard & Poor's Ratings Group (S&P) rating symbols and their meanings (as
published by S&P) follows:
 
     1.  DEBT
 
   
          A S&P corporate or municipal debt rating is a current assessment of
     the creditworthiness of an obligor with respect to a specific obligation.
     This assessment may take into consideration obligors such as guarantors,
     insurers, or lessees.
    
 
          The debt rating is not a recommendation to purchase, sell or hold a
     security, inasmuch as it does not comment as to market price or suitability
     for a particular investor.
 
          The ratings are based on current information furnished by the issuer
     or obtained by S&P from other sources it considers reliable. S&P does not
     perform any 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 based on other circumstances.
 
        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;
 
        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.
 
<TABLE>
    <S>         <C>
    AAA         Debt rated 'AAA' has the highest rating assigned by S&P.
                Capacity to pay interest and repay principal is extremely
                strong.
 
    AA          Debt rated 'AA' has a very strong capacity to pay interest
                and repay principal and differs from the higher rated issues
                only in small degree.
 
    A           Debt rated 'A' has a strong capacity to pay interest and
                repay principal although it is somewhat more susceptible to
                the adverse effects of changes in circumstances and economic
                conditions than debt in higher rated categories.
 
    BBB         Debt rated 'BBB' is regarded as having an adequate capacity
                to pay interest and repay principal. Whereas it normally
                exhibits adequate protection parameters, adverse economic
                conditions or changing circumstances are more likely to lead
                to a weakened capacity to pay interest and repay principal
                for debt in this category than in higher rated categories.
 
    BB          Debt rated 'BB', 'B', 'CCC', 'CC' and 'C' is regarded, on
    B           balance, as predominantly speculative with respect to
    CCC         capacity to pay interest and repay principal. 'BB' indicates
    CC          the least degree of speculation and 'C' the highest. While
    C           such debt will likely have some quality and protective
                characteristics, these are outweighed by large uncertainties
                or large exposures to adverse conditions.
 
    BB          Debt rated 'BB' has less near-term vulnerability to default
                than other speculative issues. However, it faces major
                ongoing uncertainties or exposure to adverse business,
                financial, or economic conditions which could lead to
                inadequate capacity to meet timely interest and principal
                payments. The 'BB' rating category is also used for debt
                subordinated to senior debt that is assigned an actual or
                implied 'BBB-' rating.
 
    B           Debt rated 'B' has a greater vulnerability to default but
                currently has the capacity to meet interest payments and
                principal repayments. Adverse business, financial, or
                economic conditions will likely impair capacity or
                willingness to pay interest and repay principal. The 'B'
                rating category is also used for debt subordinated to senior
                debt that is assigned an actual or implied 'BB' or 'BB-'
                rating.

<PAGE>   538
    CCC         Debt rated 'CCC' has a currently identifiable vulnerability
                to default, and is dependent upon favorable business,
                financial, and economic conditions to meet timely payment of
                interest and repayment of principal. In the event of adverse
                business, financial, or economic conditions, it is not
                likely to have the capacity to pay interest and repay
                principal. The 'CCC' rating category is also used for debt
                subordinated to senior debt that is assigned an actual or
                implied 'B' or 'B-' rating.
 
    CC          The rating 'CC' typically is applied to debt subordinated to
                senior debt that is assigned an actual or implied 'CCC'
                rating.
 
    C           The rating 'C' typically is applied to debt subordinated to
                senior debt which is assigned an actual or implied 'CCC-'
                debt rating. The 'C' rating may be used to cover a situation
                where a bankruptcy petition has been filed, but debt service
                payments are continued.
 
    CI          The rating 'CI' is reserved for income bonds on which no
                interest is being paid.
 
    D           Debt rated 'D' is in payment default. The 'D' rating
                category is used when interest payments or principal
                payments are not made on the date due even if the applicable
                grace period has not expired, unless S&P believes that such
                payments will be made during such grace period. The 'D'
                rating also will be used upon the filing of a bankruptcy
                petition if debt service payments are jeopardized.
 
                PLUS (+) or MINUS (-): The ratings from 'AA' to 'CCC' may be
                modified by the addition of a plus or minus sign to show
                relative standing within the major categories.

 
<TABLE>
    <S>         <C>
    C           The letter "c" indicates that the holder's option to tender
                the security for purchase may be canceled under certain
                prestated conditions enumerated in the tender option
                documents.
 
    I           The letter "i" indicates the rating is implied. Such ratings
                are assigned only on request to entities that do not have
                specific debt issues to be rated. In addition, implied
                ratings are assigned to governments that have not requested
                explicit ratings for specific debt issues. Implied ratings
                on governments represent the sovereign ceiling or upper
                limit for ratings on specific debt issues of entities
                domiciled in the country.
 
    L           The letter "L" indicates that the rating pertains to the
                principal amount of those bonds to the extent that the
                underlying deposit collateral is federally insured and
                interest is adequately collateralized. In the case of
                certificates of deposit, the letter "L" indicates that the
                deposit, combined with other deposits being held in the same
                right and capacity, will be honored for principal and
                accrued pre-default interest up to the federal insurance
                limits within 30 days after closing of the insured
                institution or, in the event that the deposit is assumed by
                a successor insured institution, upon maturity.
 
    P           The letter "p" indicates that the rating is provisional. A
                provisional rating assumes the successful completion of the
                project being financed by the debt being rated and indicates
                that payment of debt service requirements is largely or
                entirely dependent upon the successful and timely completion
                of the project. This rating, however, while addressing
                credit quality subsequent to completion of the project,
                makes no comment on the likelihood of, or the risk of
                default upon failure of, such completion. The investor
                should exercise his own judgement with respect to such
                likelihood and risk.
 
                * Continuance of the rating is contingent upon S&P's receipt
                of an executed copy of the escrow agreement or closing
                  documentation confirming investments and cash flows.
 
    NR          Indicates that no public rating has been requested, that
                there is insufficient information on which to base a rating,
                or that S&P does not rate a particular type of obligation as
                a matter of policy.
</TABLE>
 
  DEBT OBLIGATIONS OF ISSUERS OUTSIDE THE UNITED STATES AND ITS TERRITORIES are
rated on the same basis as domestic corporate and municipal issues. The ratings
measure the creditworthiness of the obligor but do not take into account
currency exchange and related uncertainties.

  BOND INVESTMENT QUALITY STANDARDS: Under present commercial bank regulations
issued by the Comptroller of the Currency, bonds rated in the top four
categories ("AAA", "AA", "A", "BBB", commonly known as "investment grade"
ratings) are generally regarded as eligible for bank investment. In addition,
the laws of various states governing legal investments impose certain rating or
other standards for obligations eligible for investment by savings banks, trust
companies, insurance companies and fiduciaries generally.
 
     2.  MUNICIPAL NOTES
 
          A S&P note rating reflects the liquidity concerns and market access
     risks unique to notes. Notes maturing in 3 years or less will likely
     receive a note rating. Notes maturing beyond 3 years will most likely
     receive a long-term debt rating.
 
          The following criteria will be used in making that assessment.
 
          -- Amortization schedule (the larger the final maturity relative to
             other maturities, the more likely it will be treated as a note).
 
          -- Source of payment (the more the issue depends on the market for its
             refinancing, the more likely it will be treated as a note).
 
        The note rating symbols and definitions are as follows:
 
<TABLE>
    <S>         <C>
    SP-1        Strong capacity to pay principal and interest. Issues
                determined to possess very strong characteristics are a plus
                (+) designation.
 
    SP-2        Satisfactory capacity to pay principal and interest, with
                some vulnerability to adverse financial and economic changes
                over the term of the notes.
 
    SP-3        Speculative capacity to pay principal and interest.
</TABLE>
 
     3.  COMMERCIAL PAPER
 
          A S&P 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.
 
          Ratings are graded into several categories, ranging from 'A-1' for the
     highest-quality obligations to 'D' for the lowest. These categories are as
     follows:
 
<TABLE>
    <S>         <C>
    A-1         This highest category indicates that the degree of safety
                regarding timely payment is strong. Those issues determined
                to possess extremely strong safety characteristics are
                denoted with a plus (+) sign designation.
 
    A-2         Capacity for timely payment on issues with this designation
                is satisfactory. However, the relative degree of safety is
                not as high as for issues designated 'A-1'.
 
    A-3         Issues carrying this designation have adequate capacity for
                timely payment. They are, however, more vulnerable to the
                adverse effects of changes in circumstances than obligations
                carrying the higher designations.
 
    B           Issues rated 'B' are regarded as having only speculative
                capacity for timely payment.
 
    C           This rating is assigned to short-term debt obligations with
                a doubtful capacity for payment.
 
    D           Debt rated 'D' is in payment default. The 'D' rating
                category is used when interest payments or principal
                payments are not made on the date due, even if the
                applicable grace period has not expired, unless S&P believes
                that such payments will be made during such grace period.
</TABLE>
 
     A commercial paper rating is not a recommendation to purchase or sell a
     security. The ratings are based on current information furnished to S&P 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.
 
                                      B-24
<PAGE>   540
 
     4.  TAX-EXEMPT DUAL RATINGS
 
          S&P assigns "dual" ratings to all debt issues that have a put option
     or demand feature as part of their structure.
 
          The first rating addresses the likelihood of repayment of principal
     and interest as due, and the second rating addresses only the demand
     feature. The long-term debt rating symbols are used for bonds to denote the
     long-term maturity and the commercial paper rating symbols for the put
     option (for example, 'AAA/A-1+'). With short-term demand debt, S&P's note
     rating symbols are used with the commercial paper symbols (for example,
     'SP-1+/A-1+').
 
  MOODY'S INVESTORS SERVICE--A brief description of the applicable Moody's
Investors Service ("Moody's") rating symbols and their meanings (as published by
Moody's) follows:
 
     1.  LONG-TERM MUNICIPAL BONDS
 
<TABLE>
    <S>         <C>
    AAA         Bonds which are rated Aaa are judged to be of the best
                quality. They carry the smallest degree of investment risk
                and are generally referred to as "gilt edged." Interest
                payments are protected by a large or by an exceptionally
                stable margin and principal is secure. While the various
                protective elements are likely to change, such changes as
                can be visualized are most unlikely to impair the
                fundamentally strong position of such issues.
 
    AA          Bonds which are rated Aa are judged to be of high quality by
                all standards. Together with the Aaa group they comprise
                what are generally known as high grade bonds. They are rated
                lower than the best bonds because margins of protection may
                not be as large as in Aaa securities or fluctuation of
                protective elements may be of greater amplitude or there may
                be other elements present which make the long-term risk
                appear somewhat larger than the Aaa securities.
 
    A           Bonds which are rated A possess many favorable investment
                attributes and are to be considered as upper-medium-grade
                obligations. Factors giving security to principal and
                interest are considered adequate, but elements may be
                present which suggest a susceptibility to impairment some
                time in the future.
 
    BAA         Bonds which are rated Baa are considered as medium-grade
                obligations, (i.e., they are neither highly protected nor
                poorly secured). Interest payments and principal security
                appear adequate for the present but certain protective
                elements may be lacking or may be characteristically
                unreliable over any great length of time. Such bonds lack
                outstanding investment characteristics and in fact have
                speculative characteristics as well.
 
    BA          Bonds which are rated Ba are judged to have speculative
                elements; their future cannot be considered as well-assured.
                Often the protection of interest and principal payments may
                be very moderate, and thereby not well safeguarded during
                both good and bad times over the future. Uncertainty of
                position characterizes bonds in this class.
 
    B           Bonds which are rated B generally lack characteristics of
                the desirable investment. Assurance of interest and
                principal payments or of maintenance of other terms of the
                contract over any long period of time may be small.
 
    CAA         Bonds which are rated Caa are of poor standing. Such issues
                may be in default or there may be present elements of danger
                with respect to principal or interest.
 
    CA          Bonds which are rated Ca represent obligations which are
                speculative in a high degree. Such issues are often in
                default or have other marked shortcomings.
 
    C           Bonds which are rated C are the lowest rated class of bonds,
                and issues so rated can be regarded as having extremely poor
                prospects of ever attaining any real investment standing.
 
    CON (..)    Bonds for which the security depends upon the completion of
                some act or the fulfillment of some condition are rated
                conditionally and designated with the prefix "Con" followed
                by rating in parentheses. These are bonds secured by: (a)
                earnings of projects under construction, (b) earnings of
                projects unseasoned in operation experience, (c) rentals
                that begin when facilities are completed, or (d) payments to
                which some other limiting condition attaches the
                parenthetical rating denotes the probable credit stature
                upon completion of construction or elimination of the basis
                of the condition.
</TABLE>

<PAGE>   541
   
    (P) (..)    When applied to forward delivery bonds, indicates that the
                rating is provisional pending the delivery of the bonds. The
                rating may be revised prior to delivery if changes occur in
                the legal documents or the underlying credit quality of the
                bonds.
 
    NOTE:       Moody's applies numerical modifiers, 1, 2 and 3 in each
                generic rating classification from AA to B. The modifier 1
                indicates that the company ranks in the higher end of its
                generic rating category; the modifier 2 indicates a
                mid-range ranking; and the modifier 3 indicates that the
                company ranks in the lower end of its generic rating
                category.
 
    
 
     2.  SHORT-TERM EXEMPT NOTES
 
          Moody's ratings for state and municipal short-term obligations will be
     designated Moody's Investment Grade or (MIG). Such ratings recognize the
     differences between short-term credit risk and long-term risk. Factors
     affecting the liquidity of the borrower and short-term cyclical elements
     are critical in short-term ratings, while other factors of major importance
     in bond risk, long-term secular trends for example, may be less important
     over the short run. A short-term rating may also be assigned on an issue
     having a demand feature-variable rate demand obligation. Such ratings will
     be designated as VMIG, SG or, if the demand feature is not rated, as NR.
 
          Moody's short-term ratings are designated Moody's Investment Grade as
     MIG 1 or VMIG 1 through MIG 4 or VMIG 4. As the name implies, when Moody's
     assigns a MIG or VMIG rating, all categories define an investment grade
     situation.
 
          MIG 1/VMIG 1. This designation denotes best quality. There is present
     strong protection by established cash flows, superior liquidity support or
     demonstrated broad-based access to the market for refinancing.
 
          MIG 2/VMIG 2. This designation denotes high quality. Margins of
     protection are ample although not so large as in the preceding group.
 
          MIG 3/VMIG 3. This designation denotes favorable quality. All security
     elements are accounted for but there is lacking the undeniable strength of
     the preceding grades. Liquidity and cash flow protection may be narrow and
     market access for refinancing is likely to be less well established.
 
          MIG 4/VMIG 4. This designation denotes adequate quality. Protection
     commonly regarded as required of an investment security is present and
     although not distinctly or predominantly speculative, there is specific
     risk.
 
          SG. This designation denotes speculative quality. Debt instruments in
     this category lack margins of protection.
 
     3.  TAX-EXEMPT COMMERCIAL PAPER
 
   
          Moody's short-term debt ratings are opinions of the ability of issuers
     to repay punctually promissory obligations not having an original maturity
     in excess of nine months. Moody's makes no representation that such
     obligations are exempt from registration under the Securities Act of 1933,
     nor does it represent that any specific note is a valid obligation of a
     rated issuer or issued in conformity with any applicable law.
    
 
   
          Moody's employs the following three designations, all judged to be
     investment grade, to indicate the relative repayment ability of rated
     issuers:
    
 
   
       Issuers rated Prime-1 (for related supporting institutions) have a
     superior capacity for repayment of short-term promissory obligations.
     Prime-1 repayment capacity will normally be evidenced by the following
     characteristics:
    
 
   
         - Leading market positions in well established industries.
    
 
   
         - High rates of return on funds employed.
    
 
   
         - Conservative capitalization structures with moderate reliance on debt
           and ample asset protection.
    
 
   
         - Broad margins in earning coverage of fixed financial charges and high
           internal cash generation.
    
 
                                      B-26
<PAGE>   542
 
   
         - Well established access to a range of financial markets and assured
           sources of alternate liquidity.
    
 
   
       Issuers rated Prime-2 (or related supporting institutions) have a strong
     capacity for repayment of short-term promissory obligations. This will
     normally be evidenced by many of the characteristics cited above but to a
     lesser degree. Earnings trends and coverage ratios, while sound, will be
     more subject to variation. Capitalization characteristics, while still
     appropriate, may be more affected by external conditions. Ample alternate
     liquidity is maintained.
    
 
   
       Issuers rated Prime-3 (or related supporting institutions) have an
     acceptable capacity for repayment of short-term promissory obligations. The
     effects of industry characteristics and market composition may be more
     pronounced. Variability in earnings and profitability may result in changes
     in the level of debt protection measurements and the requirement for
     relatively high financial leverage. Adequate alternate liquidity is
     maintained.
    
 
   
       Issuers rated Not Prime do not fall within any of the Prime rating
     categories.

  Each of the trustees holds the same position with each of the funds in the
Fund Complex. As of December 31, 1996, there were 51 funds in the Fund Complex.
Each trustee who is not an affiliated person of VKAC, the Advisers, the
Distributor, ACCESS or Morgan Stanley (each a "Non-Affiliated Trustee") is
compensated by an annual retainer and meeting fees for services to the funds in
the Fund Complex. Each fund in the Fund Complex provides a deferred compensation
plan to its Non-Affiliated Trustees that allows trustees to defer receipt of
their compensation and earn a return on such deferred amounts based upon the
return of the common shares of the funds in the Fund Complex as more fully
described below. Each fund in the Fund Complex also provides a retirement plan
to its Non-Affiliated Trustees that provides Non-Affiliated Trustees with
compensation after retirement, provided that certain eligibility requirements
are met as more fully described below.
    
 
   
  The compensation of each Non-Affiliated Trustee from each fund in the Fund
Complex advised by Advisory Corp. (each a "VK Fund" and collectively the "VK
Funds") includes an annual retainer in an amount equal to $2,500 per calendar
year, due in four quarterly installments on the first business day of each
calendar quarter. Each Non-Affiliated Trustee receives a per meeting fee from
each VK Fund in the amount of $125 per regular quarterly meeting attended by the
Non-Affiliated Trustee, due on the date of such meeting, plus reasonable
expenses incurred by the Non-Affiliated Trustee in connection with his or her
services as a trustee. Each Non-Affiliated Trustee receives a per meeting fee
from each VK Fund in the amount of $125 per special meeting attended by the
Non-Affiliated Trustee, due on the date of such meeting, plus reasonable
expenses incurred by the Non-Affiliated Trustee in connection with his or her
services as a trustee, provided that no compensation will be paid in connection
with certain telephonic special meetings.
    
 
   
  The compensation of each Non-Affiliated Trustee from the funds in the Fund
Complex advised by Asset Management (each an "AC Fund" or collectively the "AC
Funds") includes an annual retainer in an amount equal to $35,000 per calendar
year, due in four quarterly installments on the first business day of each
calendar quarter. The AC Funds pay each Non-Affiliated Trustee a per meeting fee
in the amount of $2,000 per regular quarterly meeting attended by the
Non-Affiliated Trustee, due on the date of such meeting, plus reasonable
expenses incurred by the Non-Affiliated Trustee in connection with his or her
services as a trustee. Payment of the annual retainer and the regular meeting
fee is allocated among the AC Funds (i) 50% on the basis of the relative net
assets of each AC Fund to the aggregate net assets of all the AC Funds and (ii)
50% equally to each AC Fund, in each case as of the last business day of the
preceding calendar quarter. Each AC Fund which is the subject of a special
meeting of the trustees generally pays each Non-Affiliated Trustee a per meeting
fee in the amount of $125 per special meeting attended by the Non-Affiliated
Trustee, due on the date of such meeting, plus reasonable expenses incurred by
the Non-Affiliated Trustee in connection with his or her services as a trustee,
provided that no compensation will be paid in connection with certain telephonic
special meetings.
    
 
   
  The trustees approved an aggregate compensation cap with respect to funds in
the Fund Complex of $84,000 per Non-Affiliated Trustee per year (excluding any
retirement benefits) for the period July 22, 1995 through December 31, 1996,
subject to the net assets and the number of funds in the Fund Complex as of July
21, 1995 and certain other exceptions. For the calendar year ended December 31,
1996, certain trustees received aggregate compensation from the funds in the
Fund Complex over $84,000 due to compensation received but not subject to the
cap, including compensation from new funds added to the Fund Complex after July
22, 1995 and certain special meetings in 1996. In addition, each of Advisory
Corp. or Asset Management, as the case may be, agreed to reimburse each fund in
the Fund Complex through December 31, 1996 for any increase in the aggregate
trustee's compensation over the aggregate compensation paid by such fund in its
1994 fiscal year, provided that if a fund did not exist for the entire 1994
fiscal year appropriate adjustments will be made.
    
 
   
  Each Non-Affiliated Trustee generally can elect to defer receipt of all or a
portion of the compensation earned by such Non-Affiliated Trustee until
retirement. Amounts deferred are retained by the Fund and earn a rate of return
determined by reference to the return on the common shares of such Fund or other
funds in the Fund Complex as selected by the respective Non-Affiliated Trustee,
with the same economic effect as if such Non-Affiliated Trustee had invested in
one or more funds in the Fund Complex. To the extent permitted by the 1940 Act,
the Fund may invest in securities of those funds selected by the Non-Affiliated
Trustees in
    
 
                                      B-32

order to match the deferred compensation obligation. The deferred compensation
plan is not funded and obligations thereunder represent general unsecured claims
against the general assets of the Fund.
    
 
   
  Each fund in the Fund Complex has adopted a retirement plan. Under the Fund's
retirement plan, a Non-Affiliated Trustee who is receiving trustee's
compensation from the Fund prior to such Non-Affiliated Trustee's retirement,
has at least 10 years of service (including years of service prior to adoption
of the retirement plan) and retires at or after attaining the age of 60, is
eligible to receive a retirement benefit equal to $2,500 per year for each of
the ten years following such trustee's retirement from the Fund. Trustees
retiring prior to the age of 60 or with fewer than 10 years but more than 5
years of service may receive reduced retirement benefits from the Fund. Each
trustee has served as a member of the Board of Trustees since he or she was
first appointed or elected in the year set forth below. The retirement plan
contains a Fund Complex retirement benefit cap of $60,000 per year. Asset
Management has reimbursed each AC Fund for the expenses related to the
retirement plan through December 31, 1996.
    
 
   
  Additional information regarding compensation and benefits for trustees is set
forth below. As indicated in the notes accompanying the table, the amounts
relate to either the Trust's most recently completed fiscal year or the Fund
Complex' most recently completed calendar year ended December 31, 1996.

*  Currently a member of the Board of Trustees. Mr. Phillip B. Rooney also is a
   current member of the Board of Trustees but is not included in the
   compensation table because he did not serve on the Board of Trustees or
   receive any compensation from the Trust prior to April 14, 1997. Messrs.
   McDonnell and Powell, also trustees of the Trust during all or a portion of
   the Trust's last fiscal year, are not included in the compensation table
   because they are affiliated persons of the Advisers and are not eligible for
   compensation or retirement benefits from the Trust.
    
 
   
(1) Persons not designated by an asterisk are not currently members of the Board
    of Trustees, but were members of the Board of Trustees during the Trust's
    most recently completed fiscal year. Messrs. Gaughan and Rees retired from
    the Board of Trustees on January 26, 1996 and January 29, 1996,
    respectively. Mr. Sheehan was removed from the Board of Trustees effective
    January 29, 1996. Messrs. Hilsman, Miller and Woodside retired from the
    Board of Trustees on December 31, 1996.
    
 
   
(2) The amounts shown in this column represent the aggregate compensation before
    deferral from all eight series of the Trust, including the Fund, with
    respect to the Trust's fiscal year ended December 31, 1996.

    The detail of aggregate compensation before deferral for each series,
    including the Fund, are shown in Table A below. Certain trustees deferred
    compensation from the Trust during the fiscal year ended December 31, 1996;
    the aggregate compensation deferred from all eight series of the Trust,
    including the Fund, is as follows: Mr. Branagan, $5,750; Mr. Gaughan,
    $3,750; Ms. Heagy, $15,000; Mr. Kennedy, $9,500; Mr. Miller, $20,000; Mr.
    Nelson, $20,000; Mr. Robinson, $18,000; and Mr. Whalen, $19,625. The details
    of amounts deferred for each series, including the Fund, are shown in Table
    B below. Amounts deferred are retained by the respective fund and earn a
    rate of return determined by reference to either the return on the common
    shares of such fund or other funds in the Fund Complex as selected by the
    respective Non-Affiliated Trustee, with the same economic effect as if such
    Non-Affiliated Trustee had invested in one or more funds in the Fund
    Complex. To the extent permitted by the 1940 Act, each fund may invest in
    securities of those funds selected by the Non-Affiliated Trustees in order
    to match the deferred compensation obligation. The cumulative deferred
    compensation (including interest) accrued with respect to each trustee from
    all eight series of the Trust, including the Fund, as of the Trust's fiscal
    year ended December 31, 1996 is as follows: Mr. Branagan, $5,678; Mr.
    Gaughan, $20,094; Ms. Heagy, $20,472; Mr. Kennedy, $47,294; Mr. Miller,
    $55,827; Mr. Nelson, $57,771; Mr. Robinson, $54,847; and Mr. Whalen,
    $49,269. The details of cumulative deferred compensation (including
    interest) for each series, including the Fund, are shown in Table C below.
    The deferred compensation plan is described above the Compensation Table.
    
 
   
(3) The amounts shown in this column represent the retirement benefits accrued
    by all eight series of the Trust, including the Fund, with respect to the
    Trust's fiscal year ended December 31, 1996. The details of retirement
    benefits accrued for each series, including the Fund, are shown in Table D
    below. The retirement plan is described above the Compensation Table.
    
 
   
(4) This is the estimated maximum annual benefits payable by the Trust in each
    year of the 10-year period commencing in the year of such trustee's
    retirement from the Trust. The estimated maximum annual benefit, except for
    trustees who have retired or are near retirement, is based upon $2,500 per
    series assuming: the trustee has 10 or more years of service on the Board of
    Trustees (including years of service prior to the adoption of the retirement
    plan) and retires at or after attaining the age of 60. Trustees retiring
    prior to the age of 60 or with fewer than 10 years of service for a series
    of the Trust may receive reduced retirement benefits from such series. The
    actual annual benefit may be less if the trustee is subject to the Fund
    Complex retirement benefit cap or if the trustee is not fully vested at the
    time of retirement. Each Non-Affiliated Trustee of the Board of Trustees has
    served as a member of the Board of Trustees since he or she was first
    appointed or elected in the year set forth in Table E below.
    
 
   
(5) The amounts shown in this column represent the aggregate compensation paid
    by all 51 of the investment companies in the Fund Complex as of December 31,
    1996 before deferral by the trustees under the deferred compensation plan.
    Certain trustees deferred all or a portion of their aggregate compensation
    from the Fund Complex during the calendar year ended December 31, 1996. The
    deferred compensation earns a rate of return determined by reference to the
    return on the shares of the funds in the Fund Complex as selected by the
    respective Non-Affiliated Trustee, with the same economic effect as if such
    Non-Affiliated Trustee had invested in one or more funds in the Fund
    Complex. To the extent permitted by the 1940 Act, the Fund may invest in
    securities of those investment companies selected by the Non-Affiliated
    Trustees in order to match the deferred compensation obligation. The
    trustees' Fund Complex compensation cap covered the period July 22, 1995
    through December 31, 1996. For the calendar year ended December 31, 1996,
    certain trustees received compensation over $84,000 in the aggregate due to
    compensation received but not subject to the cap, including compensation
    from new funds added to the Fund Complex after July 22, 1995 and certain
    special meetings in 1996. The Advisers and their affiliates also serve as
    investment adviser for other investment companies; however, with the
    exception of Messrs. McDonnell, Powell and Whalen, the trustees were not
    trustees of such investment companies. Combining the Fund Complex with other
    investment companies advised by the Advisers and their affiliates, Mr.
    Whalen received Total Compensation of $243,375 during the calendar year
    ended December 31, 1996.
    
 
   
  As of April 4, 1997, the trustees and officers of the Fund as a group owned
less than 1% of the shares of the Fund.

                     INVESTMENT ADVISORY AND OTHER SERVICES

Fund's investment adviser. The Adviser was incorporated as a Delaware
corporation in 1982 (and through December 31, 1987 transacted business under the
name of American Portfolio Advisory Service Inc.).
    
 
   
  The Adviser is a wholly-owned subsidiary of Van Kampen American Capital, Inc.
("VKAC"), which is a wholly-owned subsidiary of VK/AC Holding, Inc. VK/AC
Holding, Inc. is a wholly-owned subsidiary of MSAM Holdings II, Inc. which, in
turn, is a wholly-owned subsidiary of Morgan Stanley Group Inc. The principal
office of the Fund, the Adviser, the Distributor and VKAC is located at One
Parkview Plaza, Oakbrook Terrace, Illinois 60181.

subsidiaries, including Morgan Stanley & Co. Incorporated, a registered
broker-dealer and investment adviser, and Morgan Stanley International, are
engaged in a wide range of financial services. Their principal businesses

interest rates); real estate advice, financing and investing; and global
custody, securities clearance services and securities lending.
    
 
   
  On February 5, 1997, Morgan Stanley Group Inc. and Dean Witter, Discover & Co.
announced that they had entered into an Agreement and Plan of Merger to form
Morgan Stanley, Dean Witter, Discover & Co. Subject to certain conditions being
met, it is currently anticipated that the transaction will close in mid-1997.
Thereafter, Van Kampen American Capital Asset Management, Inc. will be an
indirect subsidiary of Morgan Stanley, Dean Witter, Discover & Co.
    
 
   
  Dean Witter, Discover & Co. is a financial services company with three major
businesses; full service brokerage, credit services and asset management.
    
 
   
  The investment advisory agreement between the Adviser and the Fund provides
that the Adviser will supply investment research and portfolio management,
including the selection of securities for the Fund to purchase, hold or sell and
the selection of brokers through whom the Fund's portfolio transactions are
executed. The Adviser also administers the business affairs of the Fund,
furnishes offices, necessary facilities and equipment, provides administrative
services, and permits its officers and employees to serve without compensation
as trustees of the Trust and officers of the Fund if duly elected to such
positions.
    
 
  The agreement provides that the Adviser shall not be liable for any error of
judgment or of law, or for any loss suffered by the Fund in connection with the
matters to which the agreement relates, except a loss resulting from willful
misfeasance, bad faith or gross negligence on the part of the Adviser in the
performance of its obligations and duties, or by reason of its reckless
disregard of its obligations and duties under the agreement.
 
  The Adviser's activities are subject to the review and supervision of the
Board of Trustees of the Trust, of which the Fund is a series, to whom the
Adviser renders periodic reports of the Fund's investment activities.
 
  The investment advisory agreement will continue in effect from year to year if
specifically approved by the Trustees of the Trust, of which the Fund is a
separate series, (or the Fund's shareholders) and by the disinterested Trustees
in compliance with the requirements of the 1940 Act. The agreement may be
terminated without penalty upon 60 days written notice by either party and will
automatically terminate in the event of assignment.
 
  The investment advisory agreement specifies that the Adviser will reimburse
the Fund for annual expenses of the Fund which exceed the most stringent limit
prescribed by any State in which the Fund's shares are offered for sale.
Currently, the most stringent limit in any State would require such
reimbursement to the extent that aggregate operating expenses of the Fund
(excluding interest, taxes and other expenses which may be excludable under
applicable state law) exceed in any fiscal year 2 1/2% of the average annual net
assets of the Fund up to $30 million, 2% of the average annual net assets of the
Fund of the next $70 million and 1 1/2% of the remaining average annual net
assets of the Fund. In addition to making any required reimbursements, the
Adviser may in its discretion, but is not obligated to, waive all or any portion
of its fee or assume all or any portion of the expenses of the Fund.
 
   
  For the years ended December 31, 1996, 1995 and 1994, the Fund paid advisory
expenses of $827,860, $538,373 and $297,611, respectively.
    
 
  OTHER AGREEMENTS.
 
   
  FUND ACCOUNTING AGREEMENT. The Fund has entered into an accounting services
agreement pursuant to which the Adviser provides accounting services
supplementary to those provided by the Custodian. Such services are expected to
enable the Fund to more closely monitor and maintain its accounts and records.
The Fund shares with the other Van Kampen American Capital mutual funds, in the
cost of providing such services, with 25% of such costs shared proportionately
based on the number of outstanding classes of shares per fund and with the
remaining 75 percent of such cost being paid by the Fund and such other Van
Kampen American Capital funds based proportionally on their respective net
assets.
    
 
   
  For the years ended December 31, 1996, 1995 and 1994, the Fund paid expenses
of approximately $14,705, $11,010 and $6,600, respectively, representing the
Adviser's cost of providing accounting services.

  LEGAL SERVICES AGREEMENT. The Fund and each of the other Van Kampen American
Capital funds advised by the Adviser and distributed by the Distributor have
entered into Legal Services Agreements pursuant to which Van Kampen American
Capital provides legal services, including without limitation: accurate
maintenance of the fund's minute books and records, preparation and oversight of
the fund's regulatory reports, and other information provided to shareholders,
as well as responding to day-to-day legal issues on behalf of the funds. Payment
by the Fund for such services is made on a cost basis for the salary and salary
related benefits, including but not limited to bonuses, group insurances and
other regular wages for the employment of personnel, as well as overhead and the
expenses related to the office space and the equipment necessary to render the
legal services. Other funds distributed by the Distributor also receive legal
services from Van Kampen American Capital. Of the total costs for legal services
provided to funds distributed by the Distributor, one half of such costs are
allocated equally to each fund and the remaining one half of such costs are
allocated to specific funds based on monthly time records.
    
 
   
  For the years ended December 31, 1996, 1995 and 1994, the Fund paid expenses
of approximately $9,920, $11,400 and $12,100, respectively, representing Van
Kampen American Capital, Inc.'s cost of providing legal services.
    
 
   
                     CUSTODIAN AND INDEPENDENT ACCOUNTANTS
    
 
  State Street Bank and Trust Company, 225 Franklin Street, P.O. Box 1713,
Boston, MA 02105-1713, is the custodian of the Fund and has custody of all
securities and cash of the Fund. The custodian, among other things, attends to
the collection of principal and income, and payment for and collection of
proceeds of securities bought and sold by the Fund.
 
   
  The independent accountants for the Fund are KPMG Peat Marwick LLP, Chicago,
Illinois. The selection of independent accountants will be subject to
ratification by the shareholders of the Fund at any annual meeting of
shareholders.
    
 
                PORTFOLIO TRANSACTIONS AND BROKERAGE ALLOCATION
 
  The Adviser will place orders for portfolio transactions for the Fund with
broker-dealer firms giving consideration to the quality, quantity and nature of
each firms' professional services. These services include execution, clearance
procedures, wire service quotations and statistical and other research
information provided to the Fund and the investment adviser, including
quotations necessary to determine the value of the Fund's net assets. Any
research benefits derived are available for all clients of the investment
adviser. Since statistical and other research information is only supplementary
to the research efforts of the Adviser and still must be analyzed and reviewed
by its staff, the receipt of research information is not expected to materially
reduce its expenses.
 
  If it is believed to be in the best interests of the Fund, the Adviser may
place portfolio transactions with brokers who provide the types of research
service described above, even if it means the Fund will have to pay a higher
commission (or, if the broker's profit is part of the cost of the security, will
have to pay a higher price for the security) than would be the case if no weight
were given to the broker's furnishing of those research services. This will be
done, however, only if, in the opinion of the Adviser, the amount of additional
commission or increased cost is reasonable in relation to the value of such
services.
 
  In selecting among the firms believed to meet the criteria for handling a
particular transaction, the Adviser may take into consideration that certain
firms (i) provide market, statistical or other research information to the Fund
and the Adviser, (ii) have sold or are selling shares of the Fund and (iii) may
select firms that are affiliated with the Fund, its investment adviser or its
distributor and other principal underwriters.
 
  If purchases or sales of securities of the Fund and of one or more other
investment companies or clients advised by the Adviser are considered at or
about the same time, transactions in such securities will be allocated among the
several investment companies and clients in a manner deemed equitable to all by
the Adviser, taking into account the respective sizes of the funds and the
amount of securities to be purchased or sold. Although it is possible that in
some cases this procedure could have a detrimental effect on the price or
 
                                      B-38
<PAGE>   554
 
volume of the security as far as the Fund is concerned, it is also possible that
the ability to participate in volume transactions and to negotiate lower
brokerage commissions will be beneficial to the Fund.
 
  While the Adviser will be primarily responsible for the placement of the
Fund's business, the policies and practices in this regard must be consistent
with the foregoing and will at all times be subject to review by the Trustees of
the Trust, of which the Fund is a separate series.
 
  The Trustees have adopted certain policies incorporating the standards of Rule
17e-1 issued by the Securities and Exchange Commission under the 1940 Act which
requires that the commission paid to the Distributor and other affiliates of the
Fund must be reasonable and fair compared to the commissions, fees or other
remuneration received or to be received by other brokers in connection with
comparable transactions involving similar securities during a comparable period
of time. The rule and procedures also contain review requirements and require
the Adviser to furnish reports to the Trustees and to maintain records in
connection with such reviews. After consideration of all factors deemed
relevant, the Trustees will consider from time to time whether the advisory fee
will be reduced by all or a portion of the brokerage commission given to brokers
that are affiliated with the Fund.
 
                             TAX STATUS OF THE FUND
 
   
  The Trust and any of its series, including the Fund, will be treated as
separate corporations for federal income tax purposes. The Fund intends to
qualify each year and to elect to be treated as a regulated investment company
under the Code. If the Fund so qualifies and distributes each year to its
shareholders at least 90% of its net investment income (including tax-exempt
interest, taxable income and net short-term capital gain, but not net capital
gains, which are the excess of long-term capital gains over net short-term
capital losses) in each year, it will not be required to pay federal income
taxes on any income distributed to shareholders. The Fund intends to distribute
at least the minimum amount of net investment income necessary to satisfy the
90% distribution requirement. The Fund will not be subject to federal income tax
on any net capital gains distributed to shareholders.

  Pursuant to a distribution agreement, the Distributor will purchase shares of
the Fund for resale to the public, either directly or through securities
dealers, and is obligated to purchase only those shares for which it has
received purchase orders. A discussion of how to purchase and redeem the Fund's
shares and how the Fund's shares are priced is contained in the Prospectus.
    
 
   
                         DISTRIBUTION AND SERVICE PLANS
    
 
  The Fund has adopted a distribution plan (the "Distribution Plan") with
respect to each class of its shares pursuant to Rule 12b-1 under the 1940 Act.
The Fund also has adopted a service plan (the "Service Plan") with respect to
each class of its shares. The Distribution Plan and the Service Plan sometimes
are referred to herein collectively as the Plans. The Plans provide that the
Fund may spend a portion of the Fund's average daily net assets attributable to
each class of shares in connection with distribution of the respective class of
shares and in connection with the provision of ongoing services to shareholders
of such class, respectively. The Plans are being implemented through an
agreement (the "Distribution and Service Agreement") with the Distributor and
sub-agreements between the Distributor and members of the NASD who are acting as
securities dealers and NASD members or eligible non-members who are acting as
brokers or agents and similar agreements between the Fund and financial
intermediaries who are acting as brokers (collectively, "Selling Agreements")
that may provide for their customers or clients certain services or assistance,
which may include, but not be limited to, processing purchase and redemption
transactions, establishing and maintaining shareholder accounts regarding the
Fund, and such other services as may be agreed to from time to time and as may
be permitted by applicable statute, rule or regulation. Brokers, dealers and
financial intermediaries that have entered into sub-agreements with the
Distributor and sell shares of the Fund are referred to herein as "financial
intermediaries."
 
   
  Under the Distribution and Service Agreement and the Selling Agreements,
financial intermediaries that sold shares prior to July 1, 1987, or prior to the
beginning of the calendar quarter in which the Selling Agreement between the
Fund and such financial intermediary was approved by the Fund's Board of
Trustees (an "Implementation Date") are not eligible to receive compensation
pursuant to such Distribution and Service Agreement or Selling Agreement. To the
extent that there remain outstanding shares of the Fund that were purchased
prior to all Implementation Dates, the percentage of the total average daily net
asset value of a class of shares that may be utilized pursuant to the
Distribution and Service Agreement will be less than the maximum percentage
amount permissible with respect to such class of shares under the Distribution
and Service Agreement.
    
 
   
  The Distributor must submit quarterly reports to the Board of Trustees of the
Trust, of which the Fund is a series, setting forth separately by class of
shares all amounts paid under the Plans and the purposes for which such
expenditures were made, together with such other information as from time to
time is reasonably requested by the Trustees. The Plans provide that they will
continue in full force and effect from year to year so long as such continuance
is specifically approved by a vote of the Trustees, and also by a vote of the
disinterested Trustees, cast in person at a meeting called for the purpose of
voting on the Plans. Each of the Plans may not be amended to increase materially
the amount to be spent for the services described therein with respect to either
class of shares without approval by a vote of a majority of the outstanding
voting shares of such class, and all material amendments to either of the Plans
must be approved by the Trustees and also by the disinterested Trustees. Each of
the Plans may be terminated with respect to either class of shares at any time
by a vote of a majority of the disinterested Trustees or by a vote of a majority
of the outstanding voting shares of such class.

  For the fiscal year ended December 31, 1996, the Fund's aggregate expenses
under the Plans for Class A shares were $345,296 or 0.24% of the Class A shares'
average net assets. Such expenses were paid to reimburse the Distributor for
payments made to financial intermediaries for servicing Fund shareholders and
for administering the Plans. For the fiscal year ended December 31, 1996, the
Fund's aggregate expenses under the Plans for Class B shares were $267,446 or
1.00% of the Class B shares' average net assets. Such expenses were paid to
reimburse the Distributor for the following payments: $200,485 for commissions
and transaction fees paid to financial intermediaries in respect of sales of
Class B shares of the Fund and $66,961 for fees paid to financial intermediaries
for servicing Class B shareholders and administering the Plans. For the fiscal
year ended December 31, 1996, the Fund's aggregate expenses under the Plans for
Class C shares were $19,428 or 1.00% of the Class C shares' average net assets.
Such expenses were paid to reimburse the Distributor for the following payments:

                            PERFORMANCE INFORMATION
 
  From time to time marketing materials may provide a portfolio manager update,
an adviser update or discuss general economic conditions and outlooks. The
Fund's marketing materials may also show the Fund's asset class diversification,
top five sectors, ten largest holdings and other Fund asset structures, such as
duration, maturity, coupon, NAV, rating breakdown, AMT exposure and number of
issues in the portfolio. Materials may also mention how Van Kampen American
Capital believes the Fund compares relative to other Van Kampen American Capital
funds. Materials may also discuss the Dalbar Financial Services study from 1984
to 1994 which studied investor cash flow into and out of all types of mutual
funds. The ten year study found that investors who bought mutual fund shares and
held such shares outperformed investors who bought and sold. The Dalbar study
conclusions were consistent regardless of if shareholders purchased their funds
in direct or sales force distribution channels. The study showed that investors
working with a professional representative have tended over time to earn higher
returns than those who invested directly. The Fund will also be marketed on the
Internet.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
The Board of Trustees and Shareholders of
Van Kampen American Capital California Insured Tax Free Fund:
 
We have audited the accompanying statement of assets and liabilities of Van
Kampen American Capital California Insured Tax Free Fund (the "Fund"), including
the portfolio of investments, as of December 31, 1996, and the related statement
of operations for the year then ended, the statement of changes in net assets
for each of the two years in the period then ended, and the financial highlights
for each of the periods presented. These financial statements and financial
highlights are the responsibility of the Fund's management. Our responsibility
is to express an opinion on these financial statements and financial highlights
based on our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of
December 31, 1996, by correspondence with the custodian. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of Van
Kampen American Capital California Insured Tax Free Fund as of December 31,
1996, the results of its operations for the year then ended, the changes in its
net assets for each of the two years in the period then ended, and the financial
highlights for each of the periods presented, in conformity with generally
accepted accounting principles.

                               December 31, 1996
- --------------------------------------------------------------------------------
 
1. SIGNIFICANT ACCOUNTING POLICIES
 
Van Kampen American Capital California Insured Tax Free Fund (the "Fund") is
organized as a series of the Van Kampen American Capital Tax Free Trust, a
Delaware business trust, and is registered as a diversified open-end management
investment company under the Investment Company Act of 1940, as amended. The
Fund's investment objective is to provide California investors with a high level
of current income exempt from federal and California income taxes, with
liquidity and safety of principal, primarily through investment in a diversified
portfolio of insured California municipal securities. The Fund commenced
investment operations on December 13, 1985. The distribution of the Fund's Class
B shares and Class C shares commenced on May 1, 1993 and August 13, 1993,
respectively.
 
    The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. The
preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.
 
A. SECURITY VALUATION--Investments are stated at value using market quotations
or, if such valuations are not available, estimates obtained from yield data
relating to instruments or securities with similar characteristics in accordance
with procedures established in good faith by the Board of Trustees. Short-term
securities with remaining maturities of 60 days or less are valued at amortized
cost.
 
B. SECURITY TRANSACTIONS--Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis. The
Fund may purchase and sell securities on a "when issued" or "delayed delivery"
basis, with settlement to occur at a later date. The value of the security so
purchased is subject to market fluctuations during this period. The Fund will
maintain, in a segregated account with its custodian, assets having an aggregate
value at least equal to the amount of the when issued or delayed delivery
purchase commitments until payment is made. At December 31, 1996, there were no
when issued or delayed delivery purchase commitments.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
                               December 31, 1996
- --------------------------------------------------------------------------------
 
C. INVESTMENT INCOME--Interest income is recorded on an accrual basis. Bond
premium and original issue discount are amortized over the expected life of each
applicable security.
 
D. FEDERAL INCOME TAXES--It is the Fund's policy to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income, if any, to its shareholders.
Therefore, no provision for federal income taxes is required.
 
    The Fund intends to utilize provisions of the Federal income tax laws which
allow it to carry a realized capital loss forward for eight years following the
year of the loss and offset such losses against any future realized capital
gains. At December 31, 1996, the Fund had an accumulated capital loss
carryforward for tax purposes of $5,070,220, which will expire between December
31, 2002 and December 31, 2003.
 
E. DISTRIBUTION OF INCOME AND GAINS--The Fund declares daily and pays monthly
dividends from net investment income. Net realized gains, if any, are
distributed annually. For the year ended December 31, 1996, 99.7% of the income
distributions made by the Fund were exempt from federal income taxes.
 
    Due to inherent differences in the recognition of income, expenses and
realized gains/losses under generally accepted accounting principles and federal
income tax purposes, the amount of distributable net investment income may
differ between book and federal income tax purposes for a particular period.
These differences are temporary in nature, but may result in book basis
distribution in excess of net investment income for certain periods.
 
    Permanent differences between book and tax basis reporting for the 1996
fiscal year have been identified and appropriately reclassified. Permanent book
and tax basis differences relating to the recognition of certain expenses which
are not deductible for tax purposes totaling $76,529 were reclassified from
accumulated undistributed net investment income to capital.
 
F. INSURANCE EXPENSE--The Fund typically invests in insured bonds. Any portfolio
securities not specifically covered by a primary insurance policy are insured
secondarily through the Fund's portfolio insurance policy. Insurance premiums
are based on the daily balances of uninsured bonds in the portfolio of
investments and are charged to expense on an accrual basis. The insurance policy
guarantees the timely payment of principal and interest on the securities in the
Fund's portfolio.

2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES
Under the terms of the Fund's Investment Advisory Agreement, Van Kampen American
Capital Investment Advisory Corp. (the "Adviser") will provide investment advice
and facilities to the Fund for an annual fee payable monthly as follows:

</TABLE>
 
    Certain legal expenses are paid to Skadden, Arps, Slate, Meagher & Flom,
counsel to the Fund, of which a trustee of the Fund is an affiliated person.
 
    For the year ended December 31, 1996, the Fund recognized expenses of
approximately $24,600, representing Van Kampen American Capital Distributors,
Inc.'s or its affiliates' (collectively "VKAC") cost of providing accounting,
cash management and legal services to the Fund.
 
    ACCESS Investor Services, Inc. ("ACCESS"), an affiliate of the Adviser,
serves as the shareholder servicing agent of the Fund. For the year ended
December 31, 1996, the Fund recognized expenses of approximately $142,100,
representing ACCESS' cost of providing transfer agency and shareholder services
plus a profit.
 
    Additionally, for the year ended December 31, 1996, the Fund reimbursed VKAC
approximately $63,700 related to the direct cost of consolidating the VKAC
open-end fund complex. Payment was contingent upon the realization by the Fund
of cost efficiencies in certain expense categories resulting from the
consolidation.
 
    Certain officers and trustees of the Fund are also officers and directors of
VKAC. The Fund does not compensate its officers or trustees who are officers of
VKAC. For the year ended December 31, 1996 the Adviser reimbursed the Fund for
certain trustees' compensation in connection with the July 1995 increase in the
number of trustees of the Fund.
 
    The Fund has implemented deferred compensation and retirement plans for its
trustees. Under the deferred compensation plan, trustees may elect to defer all
or a portion of their compensation to a later date. The retirement plan covers
those trustees who are not officers of VKAC.

Class B and C shares bear the expense of their respective deferred sales
arrangements, including higher distribution and service fees and incremental
transfer agency costs.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
                               December 31, 1996
- --------------------------------------------------------------------------------
 
    For the year ended December 31, 1996, VKAC, as Distributor for the Fund,
received commissions on sales of the Fund's Class A shares of approximately
$37,800 and CDSC on redeemed shares of approximately $53,600. Sales charges do
not represent expenses of the Fund.
 
4. INVESTMENT TRANSACTIONS
 
During the period, the cost of purchases and proceeds from sales of investments,
excluding short-term investments, were $60,483,216 and $65,652,566,
respectively.
 
5. DERIVATIVE FINANCIAL INSTRUMENTS
 
A derivative financial instrument in very general terms refers to a security
whose value is "derived" from the value of an underlying asset, reference rate
or index.
 
    The Fund has a variety of reasons to use derivative instruments, such as to
attempt to protect the Fund against possible changes in the market value of its
portfolio and to manage the portfolio's effective yield, maturity and duration.
All of the Fund's portfolio holdings, including derivative instruments, are
marked to market each day with the change in value reflected in the unrealized
appreciation/depreciation on securities. Upon disposition, a realized gain or
loss is recognized accordingly, except when exercising an option contract or
taking delivery of a security underlying a futures contract. In these instances
the recognition of gain or loss is postponed until the disposal of the security
underlying the option or futures contract.
 
    Summarized below are the specific types of derivative financial instruments
used by the Fund.
 
A. OPTION CONTRACTS--An option contract gives the buyer the right, but not the
obligation to buy (call) or sell (put) an underlying item at a fixed exercise
price during a specified period. These contracts are generally used by the Fund
to manage the portfolio's effective maturity and duration.
 
    Transactions in options for the year ended December 31, 1996 were as
follows:

B. FUTURES CONTRACTS--A futures contract is an agreement involving the delivery
of a particular asset on a specified future date at an agreed upon price. The
Fund generally

- --------------------------------------------------------------------------------
 
invests in futures on U.S. Treasury Bonds and the Municipal Bond Index and
typically closes the contract prior to the delivery date. These contracts are
generally used to manage the portfolio's effective maturity and duration.
 
    Upon entering into futures contracts, the Fund maintains, in a segregated
account with its custodian, securities with a value equal to its obligation
under the futures contracts. During the period the futures contract is open,
payments are received from or made to the broker based upon changes in the value
of the contract (the variation margin).
 
    Transactions in futures contracts, each with a notional par value of
$100,000, for the year ended December 31, 1996, were as follows:

</TABLE>
 
B. INDEXED SECURITIES--These instruments are identified in the portfolio of
investments. The price of these securities may be more volatile than the price
of a comparable fixed rate security.
 
    An Inverse Floating security is one where the coupon is inversely indexed to
a short-term floating interest rate multiplied by a specified factor. As the
floating rate rises, the coupon is reduced. Conversely, as the floating rate
declines, the coupon is increased. These instruments are typically used by the
Fund to enhance the yield of the portfolio.
 
    An Embedded Swap security includes a swap component such that the fixed
coupon component of the underlying bond is adjusted by the difference between
the securities fixed swap rate and the floating swap index. These instruments
are typically used by the Fund to enhance the yield of the portfolio.
 
6. DISTRIBUTION AND SERVICE PLANS
 
The Fund and its shareholders have adopted a distribution plan pursuant to Rule
12b-1 under the Investment Company Act of 1940 and a service plan (collectively
the "Plans"). The Plans govern payments for the distribution of the Fund's
shares, ongoing shareholder services and maintenance of shareholder accounts.
 
    Annual fees under the Plans of up to .25% of Class A net assets and 1.00%
each of Class B and Class C net assets are accrued daily. Included in these fees
for the year ended December 31, 1996, are payments to VKAC of approximately
$216,200.

                             THE FUND AND THE TRUST
 
   
  Van Kampen American Capital Municipal Income Fund (the "Fund") is a separate
series of the Trust, an open-end diversified management investment company. At
present, the Fund, Van Kampen American Capital Insured Tax Free Income Fund, Van
Kampen American Capital Tax Free High Income Fund, Van Kampen American Capital
California Insured Tax Free Fund, Van Kampen American Capital Intermediate Term
Municipal Income Fund, Van Kampen American Capital Florida Insured Tax Free
Income Fund, Van Kampen American Capital New Jersey Tax Free Income Fund and Van
Kampen American Capital New York Tax Free Income Fund have been organized as
series of the Trust and have commenced investment operations. Van Kampen
American Capital California Tax Free Income Fund, Van Kampen American Capital
Michigan Tax Free Income Fund, Van Kampen American Capital Missouri Tax Free
Income Fund and Van Kampen American Capital Ohio Tax Free Income Fund have been
organized as series of the Trust but have not yet commenced investment
operations. Other series may be organized and offered in the future.
    
 
  The Trust is an unincorporated business trust established under the laws of
the state of Delaware by an Agreement and Declaration of Trust dated as of May
10, 1995, (the "Declaration of Trust"). The Declaration of Trust permits the
Trustees to create one or more separate investment portfolios and issue a series
of shares for each portfolio. The Trustees can further sub-divide each series of
shares into one or more classes of shares for each portfolio. Each share
represents an equal proportionate interest in the assets of the series with each
other share in such series and no interest in any other series. No series is
subject to the liabilities of any other series. The Declaration of Trust
provides that shareholders are not liable for any liabilities of the Trust or
any of its series, requires inclusion of a clause to that effect in every
agreement entered into by the Trust or any of its series and indemnifies
shareholders against any such liability. The Fund was originally organized as a
sub-trust of a Massachusetts business trust by a Declaration of Trust dated
August 15, 1985, under the name of Van Kampen Merritt Municipal Income Fund. The
Fund was reorganized as a series of the Trust and adopted its present name as of
July 31, 1995.
 
  Shares of the Trust entitle their holders to one vote per share; however,
separate votes are taken by each series on matters affecting an individual
series. For example, a change in investment policy for a series would be voted
upon by shareholders of only the series involved. Except as described in the
Prospectus, shares do not have cumulative voting rights, preemptive rights or
any conversion or exchange rights. The Trust does not contemplate holding
regular meetings of shareholders to elect Trustees or otherwise. However, the
holders of 10% or more of the outstanding shares may by written request require
a meeting to consider the removal of Trustees by a vote of two-thirds of the
shares then outstanding cast in person or by proxy at such meeting.
 
  The Trustees may amend the Declaration of Trust (including with respect to any
series) in any manner without shareholder approval, except that the Trustees may
not adopt any amendment adversely affecting the rights of shareholders of any
series without approval by a majority of the shares of each affected series
present at a meeting of shareholders (or such higher vote as may be required by
the Investment Company Act of 1940, as amended (the "1940 Act") or other
applicable law) and except that the Trustees cannot amend the Declaration of
Trust to impose any liability on shareholders, make any assessment on shares or
impose liabilities on the Trustees without approval from each affected
shareholder or Trustee, as the case may be.
 
  Statements contained in this Statement of Additional Information as to the
contents of any contract or other document referred to are not necessarily
complete, and, in each instance, reference is made to the copy of such contract
or other document filed as an exhibit to the Registration Statement of which
this Statement of Additional Information forms a part, each such statement being
qualified in all respects by such reference.
 
                      INVESTMENT POLICIES AND RESTRICTIONS
 
  The investment objective of the Fund is set forth in the Prospectus under the
caption "Investment Objective and Policies." There can be no assurance that the
Fund will achieve its investment objective.
 
  Fundamental investment restrictions limiting the investments of the Fund
provide that the Fund may not:
 
   1. With respect to 75% of its total assets, purchase any securities (other
      than obligations guaranteed by the United States Government or by its
      agencies or instrumentalities), if, as a result, more than 5% of the
      Fund's total assets (taken at current market value) would then be invested
      in securities of a single
 
                                       B-2
<PAGE>   579
 
   
      issuer or, if, as a result, the Fund would hold more than 10% of the
      outstanding voting securities of an issuer, except that the Fund may
      purchase securities of other investment companies to the extent permitted
      by (i) the 1940 Act, as amended from time to time, (ii) the rules and
      regulations promulgated by the SEC under the 1940 Act, as amended from
      time to time, or (iii) an exemption or other relief from the provisions of
      the 1940 Act.
    
 
   
   2. Invest more than 25% of its assets in a single industry. (As described in
      the Prospectus, the Fund may from time to time invest more than 25% of its
      assets in a particular segment of the municipal bond market; however, the
      Fund will not invest more than 25% of its assets in industrial development
      bonds in a single industry), except that the Fund may purchase securities
      of other investment companies to the extent permitted by (i) the 1940 Act,
      as amended from time to time, (ii) the rules and regulations promulgated
      by the SEC under the 1940 Act, as amended from time to time, or (iii) an
      exemption or other relief from the provisions of the 1940 Act.
    
 
   3. Borrow money, except from banks for temporary purposes and then in amounts
      not in excess of 5% of the total asset value of the Fund, or mortgage,
      pledge, or hypothecate any assets except in connection with a borrowing
      and in amounts not in excess of 10% of the total asset value of the Fund.
      Borrowings may not be made for investment leverage, but only to enable the
      Fund to satisfy redemption requests where liquidation of portfolio
      securities is considered disadvantageous or inconvenient. In this
      connection, the Fund will not purchase portfolio securities during any
      period that such borrowings exceed 5% of the total asset value of the
      Fund. Notwithstanding this investment restriction, the Fund may enter into
      when issued and delayed delivery transactions as described in the
      Prospectus.
 
   4. Make loans of money or property to any person, except to the extent the
      securities in which the Fund may invest are considered to be loans and
      except that the Fund may lend money or property in connection with
      maintenance of the value of, or the Fund's interest with respect to, the
      securities owned by the Fund.
 
   5. Buy any securities "on margin." Neither the deposit of initial or
      maintenance margin in connection with hedging transactions nor short term
      credits as may be necessary for the clearance of transactions is
      considered the purchase of a security on margin.
 
   6. Sell any securities "short," write, purchase or sell puts, calls or
      combinations thereof, or purchase or sell interest rate or other financial
      futures or index contracts or related options, except as hedging or risk
      management transactions in accordance with the requirements of the
      Securities and Exchange Commission and the Commodity Futures Trading
      Commission.
 
   7. Act as an underwriter of securities, except to the extent the Fund may be
      deemed to be an underwriter in connection with the sale of securities held
      in its portfolio.
 
   
   8. Make investments for the purpose of exercising control or participation in
      management, except to the extent that exercise by the Fund of its rights
      under agreements related to securities owned by the Fund would be deemed
      to constitute such control or participation, except that the Fund may
      purchase securities of other investment companies to the extent permitted
      by (i) the 1940 Act, as amended from time to time, (ii) the rules and
      regulations promulgated by the SEC under the 1940 Act, as amended from
      time to time, or (iii) an exemption or other relief from the provisions of
      the 1940 Act.
    
 
   
   9. Invest in securities issued by other investment companies except as part
      of a merger, reorganization or other acquisition and extent permitted by
      (i) the 1940 Act, as amended from time to time, (ii) the rules and
      regulations promulgated by the SEC under the 1940 Act, as amended from
      time to time, or (iii) an exemption or other relief from the provisions of
      the 1940 Act.
    
 
  10. Invest in oil, gas or mineral leases or in equity interests in oil, gas,
      or other mineral exploration or development programs.
 
  11. Purchase or sell real estate, commodities or commodity contracts, except
      to the extent the securities the Fund may invest in are considered to be
      interest in real estate, commodities or commodity contracts or
 
                                       B-3
<PAGE>   580
 
      to the extent the Fund exercises its rights under agreements relating to
      such securities (in which case the Fund may own, hold, foreclose,
      liquidate or otherwise dispose of real estate acquired as a result of a
      default on a mortgage), and except to the extent the options and futures
      and index contracts in which such Funds may invest for hedging and risk
      management purposes are considered to be commodities or commodities
      contracts.
 
  The Fund may not change any of these investment restrictions nor any other
fundamental policy as they apply to the Fund without the approval of the lesser
of (i) more than 50% of the Fund's outstanding shares or (ii) 67% of the Fund's
shares present at a meeting at which the holders of more than 50% of the
outstanding shares are present in person or by proxy. As long as the percentage
restrictions described above are satisfied at the time of the investment or
borrowing, the Fund will be considered to have abided by those restrictions even
if, at a later time, a change in values or net assets causes an increase or
decrease in percentage beyond that allowed.
 
  The Fund generally will not engage in the trading of securities for the
purpose of realizing short-term profits, but it will adjust its portfolio as
deemed advisable in view of prevailing or anticipated market conditions to
accomplish the Fund's investment objectives. For example, the Fund may sell
portfolio securities in anticipation of a movement in interest rates. Frequency
of portfolio turnover will not be a limiting factor if the Fund considers it
advantageous to purchase or sell securities. Portfolio turnover is calculated by
dividing the lesser of purchases or sales of portfolio securities by the monthly
average value of the securities in the portfolio during the year. Securities,
including options, whose maturity or expiration date at the time of acquisition
were one year or less are excluded from such calculation. The Fund anticipates
that its annual portfolio turnover rate will normally be less than 100%.
 
                      ADDITIONAL INVESTMENT CONSIDERATIONS
 
MUNICIPAL SECURITIES
 
  Municipal securities include long-term obligations, which are often called
municipal bonds, as well as shorter term municipal notes, municipal leases, and
tax-exempt commercial paper. Under normal market conditions, longer term
municipal securities generally provide a higher yield than shorter term
municipal securities, and therefore the Fund generally expects to be invested
primarily in longer term municipal securities. The Fund will, however, invest in
shorter term municipal securities when yields are greater than yields available
on longer term municipal securities, for temporary defensive purposes and when
redemption requests are expected. The two principal classifications of municipal
bonds are "general obligation" and "revenue" or "special obligation" bonds,
which include "industrial revenue bonds." General obligation bonds are secured
by the issuer's pledge of its faith, credit, and taxing power for the payment of
principal and interest. Revenue or special obligation bonds are payable only
from the revenues derived from a particular facility or class of facilities or,
in some cases, from the proceeds of a special tax or other specific revenue
source such as from the user of the facility being financed.
 
  Also included within the general category of municipal securities are
participations in lease obligations or installment purchase contract obligations
(hereinafter collectively called "lease obligations") of municipal authorities
of entities used to finance the acquisition of equipment and facilities.
Although lease obligations do not constitute general obligations of the
municipality for which the municipality's taxing power is pledged, a lease
obligation is ordinarily backed by the municipality's covenant to budget for,
appropriate and make the payments due under the lease obligation. However,
certain lease obligations contain "non-appropriation" clauses which provide that
the municipality has no obligation to make lease or installment purchase
payments in future years unless money is appropriated for such purpose on a
yearly basis. In addition to the "non-appropriation" risk, these securities
represent a relatively new type of financing that has not yet developed the
depth of marketability associated with more conventional bonds. Although
"non-appropriation" lease obligations are often secured by the underlying
property, disposition of the property in the event of foreclosure might prove
difficult. There is no limitation on the percentage of the Fund's assets that
may be invested in "non-appropriation" lease obligations. In evaluating such
lease obligations, the Adviser will consider such factors as it deems
appropriate, which factors may include (a) whether the lease can be cancelled,
(b) the
 
                                       B-4
<PAGE>   581
 
ability of the lease obligee to direct the sale of the underlying assets, (c)
the general creditworthiness of the lease obligor, (d) the likelihood that the
municipality will discontinue appropriating funding for the leased property in
the event such property is no longer considered essential by the municipality,
(e) the legal recourse of the lease obligee in the event of such a failure to
appropriate funding and (f) any limitations which are imposed on the lease
obligor's ability to utilize substitute property or services than those covered
by the lease obligation.
 
  Also included in the term municipal securities are participation certificates
issued by state and local governments or authorities to finance the acquisition
of equipment and facilities. They may represent participations in a lease, an
installment purchase contract, or a conditional sales contract. Some municipal
leases and participation certificates may not be readily marketable.
 
  The "issuer" of municipal securities generally is deemed to be the
governmental agency, authority, instrumentality or other political subdivision,
or the non-governmental user of a revenue bond-financed facility, the assets and
revenues of which will be used to meet the payment obligations, or the guarantee
of such payment obligations, of the municipal securities.
 
  The Fund may purchase floating and variable rate demand notes, which are
municipal securities normally having a stated maturity in excess of one year,
but which permit the holder to demand payment of principal at any time, or at
specified intervals. The issuer of such notes normally has a corresponding
right, after a given period, to prepay at its discretion upon notice to the
noteholders the outstanding principal amount of the notes plus accrued interest.
The interest rate on a floating rate demand note is based on a known lending
rate, such as a bank's prime rate, and is adjusted automatically each time such
rate is adjusted. The interest rate on a variable rate demand note is adjusted
automatically at specified intervals. There generally is no secondary market for
these notes, although they are redeemable at face value. Each note purchase by
the Fund will meet the criteria established for the purchase of municipal
securities.
 
  The Fund also may invest up to 15% of its total assets in variable rate
derivative municipal securities such as inverse floaters whose rates vary
inversely with changes in market rates of interest. Such variable rate
derivative municipal securities may pay a rate of interest determined by
applying a multiple to the variable rate. The extent of increases and decreases
in the value of derivative municipal securities whose rates vary inversely with
changes in market rates of interest in response to such changes in market rates
generally will be larger than comparable changes in the value of an equal
principal amount of a fixed rate municipal security having similar credit
quality, redemption provisions and maturity. In addition, the Fund may invest in
derivative municipal securities the terms of which include elements of, or are
similar in effect to, certain Strategic Transactions in which the Fund may
engage. Such municipal securities may by their terms, for example, have economic
characteristics comparable to, among other things, a swap, cap, floor or collar
transaction with respect to such security for a period of time prior to its
stated maturity. See "Additional Investment Considerations -- Strategic
Transactions" in this Statement of Additional Information.
 
  Although the Fund will invest at least 80% of its assets in municipal
securities rated investment grade at the time of investment, municipal
securities, like other debt obligations, are subject to the risk of non-payment.
The ability of issuers of municipal securities to make timely payments of
interest and principal may be adversely impacted in general economic downturns
and as relative governmental cost burdens are allocated and reallocated among
federal, state and local governmental units. Such non-payment would result in a
reduction of income to the Fund, and could result in a reduction in the value of
the municipal security experiencing non-payment and a potential decrease in the
net asset value of the Fund. Issuers of municipal securities might seek
protection under the bankruptcy laws. In the event of bankruptcy of such an
issuer, the Fund could experience delays and limitations with respect to the
collection of principal and interest on such municipal securities and the Fund
may not, in all circumstances, be able to collect all principal and interest to
which it is entitled. To enforce its rights in the event of a default in the
payment of interest or repayment of principal, or both, the Fund may take
possession of and manage the assets securing the issuer's obligations on such
securities, which may increase the Fund's operating expenses and adversely
affect the net asset value of the Fund. Any income derived from the Fund's
ownership or operation of such assets may not be tax-exempt. In addition, the
Fund's intention to qualify as a "regulated investment company" under the
Internal Revenue Code of 1986, as amended (the "Code"), may limit the extent to
which the Fund may exercise its rights by
 
                                       B-5
<PAGE>   582
 
taking possession of such assets, because as a regulated investment company the
Fund is subject to certain limitations on its investments and on the nature of
its income.
 
  The Fund may invest up to 15% of its total assets in illiquid securities,
securities the disposition of which is subject to substantial legal or
contractual restrictions on resale and securities that are not readily
marketable. The sale of restricted and illiquid securities often requires more
time and results in higher brokerage charges or dealer discounts and other
selling expenses than does the sale of securities eligible for trading on
national securities exchanges or in the over-the-counter markets. Restricted
securities may sell at a price lower than similar securities that are not
subject to restrictions on resale. Restricted securities salable among qualified
institutional buyers without restriction pursuant to Rule 144A under the
Securities Act of 1933, as amended, that are determined to be liquid by the
Adviser under guidelines adopted by the Board of Trustees of the Trust (under
which guidelines the Adviser will consider factors such as trading activities
and the availability of price quotations), will not be treated as restricted
securities by the Fund pursuant to such rules. The Fund may, from time to time,
adopt a more restrictive limitation with respect to investment in illiquid and
restricted securities in order to comply with the most restrictive state
securities law, currently 10%. This policy does not include restricted
securities eligible for resale pursuant to Rule 144A under the Securities Act of
1933, as amended, which the Board of Trustees or the Fund's investment adviser
has determined under Board-approved guidelines to be liquid.
 
HIGH YIELD MUNICIPAL SECURITIES
 
  In normal circumstances, at least 80% of the Fund's total assets will be
invested in investment grade tax-exempt municipal securities and up to 20% of
the Fund's total assets may be invested in lower grade tax-exempt municipal
securities. The amount of available information about the financial condition of
municipal securities issuers is generally less extensive than that for corporate
issuers with publicly traded securities and the market for tax-exempt municipal
securities is considered to be generally less liquid than the market for
corporate debt obligations. Liquidity relates to the ability of a Fund to sell a
security in a timely manner at a price which reflects the value of that
security. As discussed below, the market for lower grade tax-exempt municipal
securities is considered generally to be less liquid than the market for
investment grade tax-exempt municipal securities. Further, municipal securities
in which the Fund may invest include special obligation bonds, lease
obligations, participation certificates and variable rate instruments. The
market for such securities may be particularly less liquid. The relative
illiquidity of some of the Fund's portfolio securities may adversely affect the
ability of the Fund to dispose of such securities in a timely manner and at a
price which reflects the value of such security in the Adviser's judgment.
Although the issuer of some such municipal securities may be obligated to redeem
such securities at face value, such redemption could result in capital losses to
the Fund to the extent that such municipal securities were purchased by the Fund
at a premium to face value. The market for less liquid securities tends to be
more volatile than the market for more liquid securities and market values of
relatively illiquid securities may be more susceptible to change as a result of
adverse publicity and investor perceptions than are the market values of higher
grade, more liquid securities.
 
  The Fund's net asset value will change with changes in the value of its
portfolio securities. Because the Fund will invest primarily in fixed income
municipal securities, the Fund's net asset value can be expected to change as
general levels of interest rates fluctuate. When interest rates decline, the
value of a portfolio invested in fixed income securities can be expected to
rise. Conversely, when interest rates rise, the value of a portfolio invested in
fixed income securities can be expected to decline. Net asset value and market
value may be volatile due to the Fund's investment in lower grade and less
liquid municipal securities. Volatility may be greater during periods of general
economic uncertainty.
 
  The Adviser values the Fund's investments pursuant to guidelines adopted and
periodically reviewed by the Board of Trustees. To the extent that there is no
established retail market for some of the securities in which the Fund may
invest, there may be relatively inactive trading in such securities and the
ability of the Adviser to accurately value such securities may be adversely
affected. During periods of reduced market liquidity and in the absence of
readily available market quotations for securities held in the Fund's portfolio,
the responsibility of the Adviser to value the Fund's securities becomes more
difficult and the Adviser's judgment may play a greater role in the valuation of
the Fund's securities due to the reduced availability of reliable objective
data. To the extent that the Fund invests in illiquid securities and securities
which are restricted as to
 
                                       B-6
<PAGE>   583
 
resale, the Fund may incur additional risks and costs. Illiquid and restricted
securities are particularly difficult to dispose of.
 
  Lower grade tax-exempt municipal securities generally involve greater credit
risk than higher grade municipal securities. A general economic downturn or a
significant increase in interest rates could severely disrupt the market for
lower grade tax-exempt municipal securities and adversely affect the market
value of such securities. In addition, in such circumstances, the ability of
issuers of lower grade tax-exempt municipal securities to repay principal and to
pay interest, to meet projected financial goals and to obtain additional
financing may be adversely affected. Such consequences could lead to an
increased incidence of default for such securities and adversely affect the
value of the lower grade tax-exempt municipal securities in the Fund's portfolio
and thus the Fund's net asset value. The secondary market prices of lower grade
tax-exempt municipal securities are less sensitive to changes in interest rates
than are those for higher rated tax-exempt municipal securities, but are more
sensitive to adverse economic changes or individual issuer developments. Adverse
publicity and investor perceptions, whether or not based on rational analysis,
may also affect the value and liquidity of lower grade tax-exempt municipal
securities.
 
  Yields on the Fund's portfolio securities can be expected to fluctuate over
time. In addition, periods of economic uncertainty and changes in interest rates
can be expected to result in increased volatility of the market prices of the
lower grade tax-exempt municipal securities in the Fund's portfolio and thus in
the net asset value of the Fund. Net asset value and market value may be
volatile due to the Fund's investment in lower grade and less liquid municipal
securities. Volatility may be greater during periods of general economic
uncertainty. The Fund may incur additional expenses to the extent it is required
to seek recovery upon a default in the payment of interest or a repayment of
principal on its portfolio holdings, and the Fund may be unable to obtain full
recovery thereof. In the event that an issuer of securities held by the Fund
experiences difficulties in the timely payment of principal or interest and such
issuer seeks to restructure the terms of its borrowings, the Fund may incur
additional expenses and may determine to invest additional capital with respect
to such issuer or the project or projects to which the Fund's portfolio
securities relate. Recent and proposed legislation may have an adverse impact on
the market for lower grade tax-exempt municipal securities. Recent legislation
requires federally-insured savings and loan associations to divest their
investments in lower grade bonds. Other legislation has been proposed which, if
enacted, could have an adverse impact on the market for lower grade tax-exempt
municipal securities.
 
  The Fund will rely on the Adviser's judgment, analysis and experience in
evaluating the creditworthiness of an issue. In this evaluation, the Adviser
will take into consideration, among other things, the issuer's financial
resources, its sensitivity to economic conditions and trends, its operating
history, the quality of the issuer's management and regulatory matters. The
Adviser also may consider, although it does not rely primarily on, the credit
ratings of S&P and Moody's in evaluating tax-exempt municipal securities. Such
ratings evaluate only the safety of principal and interest payments, not market
value risk. Additionally, because the creditworthiness of an issuer may change
more rapidly than is able to be timely reflected in changes in credit ratings,
the Adviser continuously monitors the issuers of tax-exempt municipal securities
held in the Fund's portfolio. The Fund may, if deemed appropriate by the
Adviser, retain a security whose rating has been downgraded below B- by S&P or
below B3 by Moody's, or whose rating has been withdrawn.
 
  Because issuers of lower grade tax-exempt municipal securities frequently
choose not to seek a rating of their municipal securities, the Adviser will be
required to determine the relative investment quality of many of the municipal
securities in the Fund's portfolio. Further, because the Fund may invest up to
20% of its total assets in these lower grade municipal securities, achievement
by the Fund of its investment objective may be more dependent upon the Adviser's
investment analysis than would be the case if the Fund were investing
exclusively in higher grade municipal securities. The relative lack of financial
information available with respect to issuers of municipal securities may
adversely affect the Adviser's ability to successfully conduct the required
investment analysis.
 
STRATEGIC TRANSACTIONS
 
  The Fund may, but is not required to, utilize various other investment
strategies as described below to hedge various market risks (such as interest
rates and broad or specific market movements) or to manage the
 
                                       B-7
<PAGE>   584
 
effective maturity or duration of the Fund's fixed-income securities. Such
strategies are generally accepted by modern portfolio managers and are regularly
utilized by many mutual funds and other institutional investors. Techniques and
instruments may change over time as new instruments and strategies are developed
or regulatory changes occur.
 
  In the course of pursuing these investment strategies, the Fund may purchase
and sell derivative instruments such as exchange-listed and over-the-counter put
and call options on securities, fixed-income indices and other financial
instruments, purchase and sell financial futures contracts and options thereon,
enter into various interest rate transactions such as swaps, caps, floors or
collars (collectively, all the above are called "Strategic Transactions").
Strategic Transactions may be used to attempt to protect against possible
changes in the market value of securities held in or to be purchased for the
Fund's portfolio resulting from securities markets fluctuations, to protect the
Fund's unrealized gains in the value of its portfolio securities, to facilitate
the sale of such securities for investment purposes, to manage the effective
maturity or duration of the Fund's portfolio, or to establish a position in the
derivatives markets as a temporary substitute for purchasing or selling
particular securities.
 
  Any or all of these investment techniques may be used at any time and there is
no particular strategy that dictates the use of one technique rather than
another, as use of any Strategic Transaction is a function of numerous variables
including market conditions. The ability of the Fund to utilize these Strategic
Transactions successfully will depend on the Adviser's ability to predict
pertinent market movements, which cannot be assured. The Fund will comply with
applicable regulatory requirements when implementing these strategies,
techniques and instruments. Strategic Transactions involving financial futures
and options thereon will be purchased, sold or entered into only for bona fide
hedging, risk management or portfolio management purposes and not for
speculative purposes.
 
  Strategic Transactions have risks associated with them including possible
default by the other party to the transaction, illiquidity and, to the extent
the Adviser's view as to certain market movements is incorrect, the risk that
the use of such Strategic Transactions could result in losses greater than if
they had not been used. Use of put and call options may result in losses to the
Fund, force the sale or purchase of portfolio securities at inopportune times or
for prices other than current market values, limit the amount of appreciation
the Fund can realize on its investments or cause the Fund to hold a security it
might otherwise sell. The use of options and futures transactions entails
certain other risks. In particular, the variable degree of correlation between
price movements of futures contracts and price movements in the related
portfolio position of the Fund creates the possibility that losses on the
hedging instrument may be greater than gains in the value of the Fund's
position. In addition, futures and options markets may not be liquid in all
circumstances and certain over-the-counter options may have no markets. As a
result, in certain markets, the Fund might not be able to close out a
transaction without incurring substantial losses, if at all. Although the use of
futures and options transactions for hedging should tend to minimize the risk of
loss due to a decline in the value of the hedged position, at the same time they
tend to limit any potential gain which might result from an increase in value of
such position. Finally, the daily variation margin requirements for futures
contracts would create a greater ongoing potential financial risk than would
purchases of options, where the exposure is limited to the cost of the initial
premium. Losses resulting from the use of Strategic Transactions would reduce
net asset value, and possibly income, and such losses can be greater than if the
Strategic Transactions had not been utilized. Income earned or deemed to be
earned, if any, by the Fund from its Strategic Transactions will generally be
taxable income of the Fund. See "Tax Status" in the Prospectus.
 
  GENERAL CHARACTERISTICS OF OPTIONS.   Put options and call options typically
have similar structural characteristics and operational mechanics regardless of
the underlying instrument on which they are purchased or sold. Thus, the
following general discussion relates to each of the particular types of options
discussed in greater detail below. In addition, many Strategic Transactions
involving options require segregation of Fund assets in special accounts, as
described below under "Use of Segregated and Other Special Accounts."
 
  A put option gives the purchaser of the option, upon payment of a premium, the
right to sell, and the writer the obligation to buy, the underlying security,
commodity, index, or other instrument at the exercise price. For instance, the
Fund's purchase of a put option on a security might be designed to protect its
holdings in the
 
                                       B-8
<PAGE>   585
 
underlying instrument (or, in some cases, a similar instrument) against a
substantial decline in the market value by giving the Fund the right to sell
such instrument at the option exercise price. A call option, upon payment of a
premium, gives the purchaser of the option the right to buy, and the seller the
obligation to sell, the underlying instrument at the exercise price. The Fund's
purchase of a call option on a security, financial future, index, or other
instrument might be intended to protect the Fund against an increase in the
price of the underlying instrument that it intends to purchase in the future by
fixing the price at which it may purchase such instrument. An American style put
or call option may be exercised at any time during the option period while a
European style put or call option may be exercised only upon expiration or
during a fixed period prior thereto. The Fund is authorized to purchase and sell
exchange listed options and over-the-counter options ("OTC options"). Exchange
listed options are issued by a regulated intermediary such as the Options
Clearing Corporation ("OCC"), which guarantees the performance of the
obligations of the parties to such options. The discussion below uses the OCC as
a paradigm, but is also applicable to other financial intermediaries.
 
  With certain exceptions, OCC issued and exchange listed options generally
settle by physical delivery of the underlying security or currency, although in
the future cash settlement may become available. Index options and Eurodollar
instruments are cash settled for the net amount, if any, by which the option is
"in-the-money" (i.e., where the value of the underlying instrument exceeds, in
the case of a call option, or is less than, in the case of a put option, the
exercise price of the option) at the time the option is exercised. Frequently,
rather than taking or making delivery of the underlying instrument through the
process of exercising the option, listed options are closed by entering into
offsetting purchase or sale transactions that do not result in ownership of the
new option.
 
  The Fund's ability to close out its position as a purchaser or seller of an
OCC or exchange listed put or call option is dependent, in part, upon the
liquidity of the option market. Among the possible reasons for the absence of a
liquid option 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 including
reaching daily price limits; (iv) interruption of the normal operations of the
OCC or an exchange; (v) inadequacy of the facilities of an exchange or 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 relevant market for that option on that exchange would cease
to exist, although outstanding options on that exchange would generally continue
to be exercisable in accordance with their terms.
 
  The hours of trading for listed options may not coincide with the hours during
which the underlying financial instruments are traded. To the extent that the
option markets close before the markets for the underlying financial
instruments, significant price and rate movements can take place in the
underlying markets that cannot be reflected in the option markets.
 
  OTC options are purchased from or sold to securities dealers, financial
institutions or other parties ("Counterparties") through direct bilateral
agreement with the Counterparty. In contrast to exchange listed options, which
generally have standardized terms and performance mechanics, all the terms of an
OTC option, including such terms as method of settlement, term, exercise price,
premium, guarantees and security, are set by negotiation of the parties. The
Fund will only sell OTC options that are subject to a buy-back provision
permitting the Fund to require the Counterparty to sell the option back to the
Fund at a formula price within seven days. The Fund expects generally to enter
into OTC options that have cash settlement provisions, although it is not
required to do so.
 
  Unless the parties provide for it, there is no central clearing or guaranty
function in an OTC option. As a result, if the Counterparty fails to make or
take delivery of the security, or other instrument underlying an OTC option it
has entered into with the Fund or fails to make a cash settlement payment due in
accordance with the terms of that option, the Fund will lose any premium it paid
for the option as well as any anticipated benefit of the transaction.
Accordingly, the Adviser must assess the creditworthiness of each such
Counterparty or any guarantor or credit enhancement of the Counterparty's credit
to determine the likelihood that the terms of the OTC option will be satisfied.
The Fund will engage in OTC option transactions only with United States
government securities dealers recognized by the Federal Reserve Bank of New York
as
 
                                       B-9
<PAGE>   586
 
"primary dealers", or broker dealers, domestic or foreign banks or other
financial institutions which have received (or the guarantors of the obligation
of which have received) a short-term credit rating of "A-1" from S&P or "P-1"
from Moody's or an equivalent rating from any other nationally recognized
statistical rating organization ("NRSRO"). The staff of the SEC currently takes
the position that, in general, OTC options on securities other than U.S.
Government securities purchased by the Fund, and portfolio securities "covering"
the amount of the Fund's obligation pursuant to an OTC option sold by it (the
cost of the sell-back plus the in-the-money amount, if any) are illiquid, and
are subject to the Fund's limitation on investing no more than 15% of its assets
in illiquid securities.
 
  If the Fund sells a call option, the premium that it receives may serve as a
partial hedge, to the extent of the option premium, against a decrease in the
value of the underlying securities or instruments in its portfolio or will
increase the Fund's income. The sale of put options can also provide income.
 
  The Fund may purchase and sell call options on securities, including U.S.
Treasury and agency securities, municipal obligations, mortgage-backed
securities and Eurodollar instruments that are traded on U.S. and foreign
securities exchanges and in the over-the-counter markets. All calls sold by the
Fund must be "covered" (i.e., the Fund must own the securities or futures
contract subject to the call) or must meet the asset segregation requirements
described below as long as the call is outstanding. Even though the Fund will
receive the option premium to help protect it against loss, a call sold by the
Fund exposes the Fund during the term of the option to possible loss of
opportunity to realize appreciation in the market price of the underlying
security or instrument and may require the Fund to hold a security or instrument
which it might otherwise have sold.
 
  The Fund may purchase and sell put options on securities including U.S.
Treasury and agency securities, mortgage-backed securities, municipal
obligations and Eurodollar instruments (whether or not it holds the above
securities in its portfolio.) The Fund will not sell put options if, as a
result, more than 50% of the Fund's assets would be required to be segregated to
cover its potential obligations under such put options other than those with
respect to futures and options thereon. In selling put options, there is a risk
that the Fund may be required to buy the underlying security at a
disadvantageous price above the market price.
 
  GENERAL CHARACTERISTICS OF FUTURES.  The Fund may enter into financial futures
contracts or purchase or sell put and call options on such futures as a hedge
against anticipated interest rate or fixed-income market changes, for duration
management and for risk management purposes. Futures are generally bought and
sold on the commodities exchanges where they are listed with payment of initial
and variation margin as described below. The purchase of a futures contract
creates a firm obligation by the Fund, as purchaser, to take delivery from the
seller the specific type of financial instrument called for in the contract at a
specific future time for a specified price (or, with respect to index futures
and Eurodollar instruments, the net cash amount). The sale of a futures contract
creates a firm obligation by the Fund, as seller, to deliver to the buyer the
specific type of financial instrument called for in the contract at a specific
future time for a specified price (or, with respect to index futures and
Eurodollar instruments, the net cash amount). Options on futures contracts are
similar to options on securities except that 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 and obligates the seller to deliver such option.
 
  The Fund's use of financial futures and options thereon will in all cases be
consistent with applicable regulatory requirements and in particular the rules
and regulations of the Commodity Futures Trading Commission and will be entered
into only for bona fide hedging, risk management (including duration management)
or other portfolio management purposes. Typically, maintaining a futures
contract or selling an option thereon requires the Fund to deposit with a
financial intermediary as security for its obligations an amount of cash or
other specified assets (initial margin) which initially is typically 1% to 10%
of the face amount of the contract (but may be higher in some circumstances).
Additional cash or assets (variation margin) may be required to be deposited
thereafter on a daily basis as the mark to market value of the contract
fluctuates. The purchase of options on financial futures involves payment of a
premium for the option without any further obligation on the part of the Fund.
If the Fund exercises an option on a futures contract it will be obligated to
post initial margin (and potential subsequent variation margin) for the
resulting futures position just as it would for any position. Futures contracts
and options thereon are generally settled by
 
                                      B-10
<PAGE>   587
 
entering into an offsetting transaction but there can be no assurance that the
position can be offset prior to settlement at an advantageous price nor that
delivery will occur.
 
  The Fund will not enter into a futures contract or related option (except for
closing transactions) if, immediately thereafter, the sum of the amount of its
initial margin and premiums on open futures contracts and options thereon would
exceed 5% of the Fund's total assets (taken at current value); however, in the
case of an option that is in-the-money at the time of the purchase, the
in-the-money amount may be excluded in calculating the 5% limitation. The
segregation requirements with respect to futures contracts and options thereon
are described below.
 
  OPTIONS ON SECURITIES INDICES AND OTHER FINANCIAL INDICES.  The Fund also may
purchase and sell call and put options on securities indices and other financial
indices and in so doing can achieve many of the same objectives it would achieve
through the sale or purchase of options on individual securities or other
instruments. Options on securities indices and other financial indices are
similar to options on a security or other instrument except that, rather than
settling by physical delivery of the underlying instrument, they settle by cash
settlement, i.e., an option on an index gives the holder the right to receive,
upon exercise of the option, an amount of cash if the closing level of the index
upon which the option is based exceeds, in the case of a call, or is less than,
in the case of a put, the exercise price of the option (except if, in the case
of an OTC option, physical delivery is specified). This amount of cash is equal
to the excess of the closing price of the index over the exercise price of the
option, which also may be multiplied by a formula value. The seller of the
option is obligated, in return for the premium received, to make delivery of
this amount. The gain or loss on an option on an index depends on price
movements in the instruments making up the market, market segment, industry or
other composite on which the underlying index is based, rather than price
movements in individual securities, as is the case with respect to options on
securities.
 
  COMBINED TRANSACTIONS.  The Fund may enter into multiple transactions,
including multiple options transactions, multiple futures transactions and
multiple interest rate transactions and any combination of futures, options and
interest rate transactions ("component" transactions), instead of a single
Strategic Transaction, as part of a single or combined strategy when, in the
opinion of the Adviser, it is in the best interests of the Fund to do so. A
combined transaction will usually contain elements of risk that are present in
each of its component transactions. Although combined transactions are normally
entered into based on the Adviser's judgment that the combined strategies will
reduce risk or otherwise more effectively achieve the desired portfolio
management goal, it is possible that the combination will instead increase such
risks or hinder achievement of the portfolio management objective.
 
  SWAPS, CAPS, FLOORS AND COLLARS.  Among the Strategic Transactions into which
the Fund may enter are interest rate and index swaps and the purchase or sale of
related caps, floors and collars. The Fund expects to enter into these
transactions primarily to preserve a return or spread on a particular investment
or portion of its portfolio, as a duration management technique or to protect
against any increase in the price of securities the Fund anticipates purchasing
at a later date. The Fund intends to use these transactions as hedges and not as
speculative investments and will not sell interest rate caps or floors where it
does not own securities or other instruments providing the income stream the
Fund may be obligated to pay. Interest rate swaps involve the exchange by the
Fund with another party of their respective commitments to pay or receive
interest, e.g., an exchange of floating rate payments for fixed rate payments
with respect to a notional amount of principal. An index swap is an agreement to
swap cash flows on a notional amount based on changes in the values of the
reference indices. The purchase of a cap entitles the purchaser to receive
payments on a notional principal amount from the party selling such cap to the
extent that a specified index exceeds a predetermined interest rate or amount.
The purchase of a floor entitles the purchaser to receive payments on a notional
principal amount from the party selling such floor to the extent that a
specified index falls below a predetermined interest rate or amount. A collar is
a combination of a cap and a floor that preserves a certain return within a
predetermined range of interest rates or values.
 
  The Fund will usually enter into swaps on a net basis, i.e., the two payment
streams are netted out in a cash settlement on the payment date or dates
specified in the instrument, with the Fund receiving or paying, as the case may
be, only the net amount of the two payments. Inasmuch as these swaps, caps,
floors and collars are entered into for good faith hedging purposes, the Adviser
and the Fund believe such obligations do not
 
                                      B-11
<PAGE>   588
 
constitute senior securities under the 1940 Act and, accordingly, will not treat
them as being subject to its borrowing restrictions. The Fund will not enter
into any swap, cap, floor or collar transaction unless, at the time of entering
into such transaction, the unsecured long-term debt of the Counterparty,
combined with any credit enhancements, is rated at least "A" by S&P or Moody's
or has an equivalent equity rating from an NRSRO or is determined to be of
equivalent credit quality by the Adviser. If there is a default by the
Counterparty, the Fund may have contractual remedies pursuant to the agreements
related to the transaction. The swap market has grown substantially in recent
years with a large number of banks and investment banking firms acting both as
principals and agents utilizing standardized swap documentation. As a result,
the swap market has become relatively liquid. Caps, floors and collars are more
recent innovations for which standardized documentation has not yet been fully
developed and, accordingly, they are less liquid than swaps.
 
   
  USE OF SEGREGATED AND OTHER SPECIAL ACCOUNTS.  Many Strategic Transactions, in
addition to other requirements, require that the Fund segregate liquid
high-grade assets with its custodian to the extent Fund obligations are not
otherwise "covered" through ownership of the underlying security, financial
instrument or currency. In general, either the full amount of any obligation by
the Fund to pay or deliver securities or assets must be covered at all times by
the securities, instruments or currency required to be delivered, or, subject to
any regulatory restrictions, an amount of cash or liquid securities at least
equal to the current amount of the obligation must be segregated with the
custodian. The segregated assets cannot be sold or transferred unless equivalent
assets are substituted in their place or it is no longer necessary to segregate
them. For example, a call option written by the Fund will require the Fund to
hold the securities subject to the call (or securities convertible into the
needed securities without additional consideration) or to segregate liquid
securities sufficient to purchase and deliver the securities if the call is
exercised. A call option sold by the Fund on an index will require the Fund to
own portfolio securities which correlate with the index or to segregate liquid
securities equal to the excess of the index value over the exercise price on a
current basis. A put option written by the Fund requires the Fund to segregate
liquid securities equal to the exercise price.
    
 
  OTC options entered into by the Fund, including those on securities, financial
instruments or indices and OCC issued and exchange listed index options, will
generally provide for cash settlement. As a result, when the Fund sells these
instruments it will only segregate an amount of assets equal to its accrued net
obligations, as there is no requirement for payment or delivery of amounts in
excess of the net amount. These amounts will equal 100% of the exercise price in
the case of a non cash-settled put, the same as an OCC guaranteed listed option
sold by the Fund, or the in-the-money amount plus any sell-back formula amount
in the case of a cash-settled put or call. In addition, when the Fund sells a
call option on an index at a time when the in-the-money amount exceeds the
exercise price, the Fund will segregate, until the option expires or is closed
out, cash or cash equivalents equal in value to such excess. OCC issued and
exchange listed options sold by the Fund other than those above generally settle
with physical delivery, and the Fund will segregate an amount of assets equal to
the full value of the option. OTC options settling with physical delivery, or
with an election of either physical delivery or cash settlement, will be treated
the same as other options settling with physical delivery.
 
  In the case of a futures contract or an option thereon, the Fund must deposit
initial margin and possible daily variation margin in addition to segregating
assets sufficient to meet its obligation to purchase or provide securities or
currencies, or to pay the amount owed at the expiration of an index- based
futures contract. Such assets may consist of cash, cash equivalents, liquid debt
or equity securities or other acceptable assets.
 
   
  With respect to swaps, the Fund will accrue the net amount of the excess, if
any, of its obligations over its entitlements with respect to each swap on a
daily basis and will segregate an amount of cash or liquid securities having a
value equal to the accrued excess. Caps, floors and collars require segregation
of assets with a value equal to the Fund's net obligation, if any.
    
 
  Strategic Transactions may be covered by other means when consistent with
applicable regulatory policies. The Fund may also enter into offsetting
transactions so that its combined position, coupled with any segregated assets,
equals its net outstanding obligation in related options and Strategic
Transactions. For example, the Fund could purchase a put option if the strike
price of that option is the same or higher than the strike price of a put option
sold by the Fund. Moreover, instead of segregating assets if the Fund held a
futures or forward contract, it could purchase a put option on the same futures
or forward contract with a strike price
 
                                      B-12
<PAGE>   589
 
as high or higher than the price of the contract held. Other Strategic
Transactions may also be offset in combinations. If the offsetting transaction
terminates at the time of or after the primary transaction no segregation is
required, but if it terminates prior to such time, assets equal to any remaining
obligation would need to be segregated.
 
  The Fund's activities involving Strategic Transactions may be limited by the
requirements of Subchapter M of the Code for qualification as a regulated
investment company. See "Tax Status" in the Prospectus.
 
                  DESCRIPTION OF MUNICIPAL SECURITIES RATINGS
 
  STANDARD & POOR'S RATINGS GROUP--A brief description of the applicable
Standard & Poor's Ratings Group (S&P) rating symbols and their meanings (as
published by S&P) follows:
 
     1.  DEBT
 
   
          A S&P corporate or municipal debt rating is a current assessment of
     the creditworthiness of an obligor with respect to a specific obligation.
     This assessment may take into consideration obligors such as guarantors,
     insurers, or lessees.
    
 
          The debt rating is not a recommendation to purchase, sell or hold a
     security, inasmuch as it does not comment as to market price or suitability
     for a particular investor.
 
          The ratings are based on current information furnished by the issuer
     or obtained by S&P from other sources it considers reliable. S&P 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 based on other circumstances.
 
        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;
 
        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.
 
<TABLE>
    <S>         <C>
    AAA         Debt rated 'AAA' has the highest rating assigned by S&P.
                Capacity to pay interest and repay principal is extremely
                strong.
 
    AA          Debt rated 'AA' has a very strong capacity to pay interest
                and repay principal and differs from the higher rated issues
                only in small degree.
 
    A           Debt rated 'A' has a strong capacity to pay interest and
                repay principal although it is somewhat more susceptible to
                the adverse effects of changes in circumstances and economic
                conditions than debt in higher rated categories.
 
    BBB         Debt rated 'BBB' is regarded as having an adequate capacity
                to pay interest and repay principal. Whereas it normally
                exhibits adequate protection parameters, adverse economic
                conditions or changing circumstances are more likely to lead
                to a weakened capacity to pay interest and repay principal
                for debt in this category than in higher rated categories.
 
    BB          Debt rated 'BB', 'B', 'CCC', 'CC' and 'C' is regarded, on
    B           balance, as predominantly speculative with respect to
    CCC         capacity to pay interest and repay principal. 'BB' indicates
    CC          the least degree of speculation and 'C' the highest. While
    C           such debt will likely have some quality and protective
                characteristics, these are outweighed by large uncertainties
                or large exposures to adverse conditions.
</TABLE>
 
                                      B-13
<PAGE>   590
    BB          Debt rated 'BB' has less near-term vulnerability to default
                than other speculative issues. However, it faces major
                ongoing uncertainties or exposure to adverse business,
                financial, or economic conditions which could lead to
                inadequate capacity to meet timely interest and principal
                payments. The 'BB' rating category is also used for debt
                subordinated to senior debt that is assigned an actual or
                implied 'BBB-' rating.
 
    B           Debt rated 'B' has a greater vulnerability to default but
                currently has the capacity to meet interest payments and
                principal repayments. Adverse business, financial, or
                economic conditions will likely impair capacity or
                willingness to pay interest and repay principal. The 'B'
                rating category is also used for debt subordinated to senior
                debt that is assigned an actual or implied 'BB' or 'BB-'
                rating.
 
    CCC         Debt rated 'CCC' has a currently identifiable vulnerability
                to default, and is dependent upon favorable business,
                financial, and economic conditions to meet timely payment of
                interest and repayment of principal. In the event of adverse
                business, financial, or economic conditions, it is not
                likely to have the capacity to pay interest and repay
                principal. The 'CCC' rating category is also used for debt
                subordinated to senior debt that is assigned an actual or
                implied 'B' or 'B-' rating.
 
    CC          The rating 'CC' typically is applied to debt subordinated to
                senior debt that is assigned an actual or implied 'CCC'
                rating.
 
    C           The rating 'C' typically is applied to debt subordinated to
                senior debt which is assigned an actual or implied 'CCC-'
                debt rating. The 'C' rating may be used to cover a situation
                where a bankruptcy petition has been filed, but debt service
                payments are continued.
 
    CI          The rating 'CI' is reserved for income bonds on which no
                interest is being paid.
 
    D           Debt rated 'D' is in payment default. The 'D' rating
                category is used when interest payments or principal
                payments are not made on the date due even if the applicable
                grace period has not expired, unless S&P believes that such
                payments will be made during such grace period. The 'D'
                rating also will be used upon the filing of a bankruptcy
                petition if debt service payments are jeopardized.
 
           PLUS (+) or MINUS (-): The ratings from 'AA' to 'CCC' may be modified
           by the addition of a plus or minus sign to show relative standing
           within the major categories.
 
<TABLE>
    <S>         <C>
    C           The letter "c" indicates that the holder's option to tender
                the security for purchase may be canceled under certain
                prestated conditions enumerated in the tender option
                documents.
 
    I           The letter "i" indicates the rating is implied. Such ratings
                are assigned only on request to entities that do not have
                specific debt issues to be rated. In addition, implied
                ratings are assigned to governments that have not requested
                explicit ratings for specific debt issues. Implied ratings
                on governments represent the sovereign ceiling or upper
                limit for ratings on specific debt issues of entities
                domiciled in the country.
 
    L           The letter "L" indicates that the rating pertains to the
                principal amount of those bonds to the extent that the
                underlying deposit collateral is federally insured and
                interest is adequately collateralized. In the case of
                certificates of deposit, the letter "L" indicates that the
                deposit, combined with other deposits being held in the same
                right and capacity, will be honored for principal and
                accrued pre-default interest up to the federal insurance
                limits within 30 days after closing of the insured
                institution or, in the event that the deposit is assumed by
                a successor insured institution, upon maturity.
</TABLE>
 
                                      B-14
<PAGE>   591
    P           The letter "p" indicates that the rating is provisional. A
                provisional rating assumes the successful completion of the
                project being financed by the debt being rated and indicates
                that payment of debt service requirements is largely or
                entirely dependent upon the successful and timely completion
                of the project. This rating, however, while addressing
                credit quality subsequent to completion of the project,
                makes no comment on the likelihood of, or the risk of
                default upon failure of, such completion. The investor
                should exercise his own judgement with respect to such
                likelihood and risk.
 
                *Continuance of the rating is contingent upon S&P's receipt
                of an executed copy of the escrow agreement or closing
                documentation confirming investments and cash flows.
 
    NR          Indicates that no public rating has been requested, that
                there is insufficient information on which to base a rating,
                or that S&P does not rate a particular type of obligation as
                a matter of policy.
 
                DEBT OBLIGATIONS OF ISSUERS OUTSIDE THE UNITED STATES AND
                ITS TERRITORIES are rated on the same basis as domestic
                corporate and municipal issues. The ratings measure the
                creditworthiness of the obligor but do not take into account
                currency exchange and related uncertainties.
 
  BOND INVESTMENT QUALITY STANDARDS: Under present commercial bank regulations
issued by the Comptroller of the Currency, bonds rated in the top four
categories ("AAA", "AA", "A", "BBB", commonly known as "investment grade"
ratings) are generally regarded as eligible for bank investment. In addition,
the laws of various states governing legal investments impose certain rating or
other standards for obligations eligible for investment by savings banks, trust
companies, insurance companies, and fiduciaries generally.
 
     2.  MUNICIPAL NOTES
 
          A S&P note rating reflects the liquidity factors and market-access
     risks unique to notes. Notes maturing in 3 years or less will likely
     receive a note rating. Notes maturing beyond 3 years will most likely
     receive a long-term debt rating.
 
        The following criteria will be used in making that assessment:
 
          -- Amortization schedule (the larger the final maturity relative to
             other maturities, the more likely the issue is to be treated as a
             note).
 
          -- Source of payment (the more the issue depends on the market for its
             refinancing, the more likely it is to be treated as a note).
 
        The note rating symbols and definitions are as follows:
 
<TABLE>
    <S>         <C>
    SP-1        Strong capacity to pay principal and interest. Issues
                determined to possess very strong characteristics are a plus
                (+) designation.
 
    SP-2        Satisfactory capacity to pay principal and interest, with
                some vulnerability to adverse financial and economic changes
                over the term of the notes.
 
    SP-3        Speculative capacity to pay principal and interest.
</TABLE>
 
     3.  COMMERCIAL PAPER
 
          A S&P commercial paper rating is a current assessment of the
     likelihood of timely payment of debt considered short-term in the relevant
     market.
 
          Ratings are graded into several categories, ranging from 'A-1' for the
     highest-quality obligations to 'D' for the lowest. These categories are as
     follows:
 
<TABLE>
    <S>         <C>
    A-1         This highest category indicates that the degree of safety
                regarding timely payment is strong. Those issues determined
                to possess extremely strong safety characteristics are
                denoted with a plus sign (+) designation.
 
    A-2         Capacity for timely payment on issues with this designation
                is satisfactory. However, the relative degree of safety is
                not as high as for issues designated 'A-1'.
</TABLE>
 
                                      B-15
<PAGE>   592
    A-3         Issues carrying this designation have adequate capacity for
                timely payment. They are, however, more vulnerable to the
                adverse effects of changes in circumstances than obligations
                carrying the higher designations.
 
    B           Issues rated 'B' are regarded as having only speculative
                capacity for timely payment.
 
    C           This rating is assigned to short-term debt obligations with
                a doubtful capacity for payment.
 
    D           Debt rated 'D' is in payment default. The 'D' rating
                category is used when interest payments or principal
                payments are not made on the date due, even if the
                applicable grace period has not expired, unless S&P believes
                that such payments will be made during such grace period.
 
     A commercial paper rating is not a recommendation to purchase or sell a
     security. The ratings are based on current information furnished to S&P 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.
 
     4.  TAX-EXEMPT DUAL RATINGS
 
          S&P assigns "dual" ratings to all debt issues that have a put option
     or demand feature as part of their structure.
 
          The first rating addresses the likelihood of repayment of principal
     and interest as due, and the second rating addresses only the demand
     feature. The long-term debt rating symbols are used for bonds to denote the
     long-term maturity and the commercial paper rating symbols for the put
     option (for example, 'AAA/A-1+'). With short-term demand debt, S&P's note
     rating symbols are used with the commercial paper rating symbols (for
     example, 'SP-1+/A-1+').
 
  MOODY'S INVESTORS SERVICE--A brief description of the applicable Moody's
Investors Service ("Moody's") rating symbols and their meanings (as published by
Moody's) follows:
 
     1.  LONG-TERM MUNICIPAL BONDS
 
<TABLE>
    <S>         <C>
    AAA         Bonds which are rated Aaa are judged to be of the best
                quality. They carry the smallest degree of investment risk
                and are generally referred to as "gilt edged." Interest
                payments are protected by a large or by an exceptionally
                stable margin and principal is secure. While the various
                protective elements are likely to change, such changes as
                can be visualized are most unlikely to impair the
                fundamentally strong position of such issues.
 
    AA          Bonds which are rated Aa are judged to be of high quality by
                all standards. Together with the Aaa group they comprise
                what are generally known as high grade bonds. They are rated
                lower than the best bonds because margins of protection may
                not be as large as in Aaa securities or fluctuation of
                protective elements may be of greater amplitude or there may
                be other elements present which make the long-term risk
                appear somewhat larger than the Aaa securities.
 
    A           Bonds which are rated A possess many favorable investment
                attributes and are to be considered as upper-medium-grade
                obligations. Factors giving security to principal and
                interest are considered adequate, but elements may be
                present which suggest a susceptibility to impairment some
                time in the future.
 
    BAA         Bonds which are rated Baa are considered as medium-grade
                obligations, (i.e., they are neither highly protected nor
                poorly secured). Interest payments and principal security
                appear adequate for the present but certain protective
                elements may be lacking or may be characteristically
                unreliable over any great length of time. Such bonds lack
                outstanding investment characteristics and in fact have
                speculative characteristics as well.
 
    BA          Bonds which are rated Ba are judged to have speculative
                elements; their future cannot be considered as well-assured.
                Often the protection of interest and principal payments may
                be very moderate, and thereby not well safeguarded during
                both good and bad times over the future. Uncertainty of
                position characterizes bonds in this class.
</TABLE>
 
                                      B-16
<PAGE>   593
   
    B           Bonds which are rated B generally lack characteristics of
                the desirable investment. Assurance of interest and
                principal payments or of maintenance of other terms of the
                contract over any long period of time may be small.
 
    CAA         Bonds which are rated Caa are of poor standing. Such issues
                may be in default or there may be present elements of danger
                with respect to principal or interest.
 
    CA          Bonds which are rated Ca represent obligations which are
                speculative in a high degree. Such issues are often in
                default or have other marked shortcomings.
 
    C           Bonds which are rated C are the lowest rated class of bonds,
                and issues so rated can be regarded as having extremely poor
                prospects of ever attaining any real investment standing.
 
    CON (..)    Bonds for which the security depends upon the completion of
                some act or the fulfillment of some condition are rated
                conditionally and designated with the prefix "Con" followed
                by the rating in parentheses. These are bonds secured by:
                (a) earnings of projects under construction, (b) earnings of
                projects unseasoned in operating experience, (c) rentals
                that begin when facilities are completed, or (d) payments to
                which some other limiting condition attaches the
                parenthetical rating denotes the probable credit stature
                upon completion of construction or elimination of the basis
                of the condition.
 
    (P) (..)    When applied to forward delivery bonds, indicates that the
                rating is provisional pending the delivery of the bonds. The
                rating may be revised prior to delivery if changes occur in
                the legal documents or the underlying credit quality of the
                bonds.
 
    NOTE:       Moody's applies numerical modifiers, 1, 2 and 3 in each
                generic rating classification from AA to B. The modifier 1
                indicates that the company ranks in the higher end of its
                generic rating category; the modifier 2 indicates a
                mid-range ranking; and the modifier 3 indicates that the
                company ranks in the lower end of its generic rating
                category.
 
    
 
     2.  SHORT-TERM EXEMPT NOTES
 
          Moody's ratings for state and municipal short-term obligations will be
     designated Moody's Investment Grade or (MIG). Such ratings recognize the
     differences between short-term credit risk and long-term risk. Factors
     affecting the liquidity of the borrower and short-term cyclical elements
     are critical in short-term ratings, while other factors of major importance
     in bond risk, long-term secular trends for example, may be less important
     over the short run. A short-term rating may also be assigned on an issue
     having a demand feature-variable rate demand obligation. Such ratings will
     be designated as VMIG, SG or, if the demand feature is not rated, as NR.
 
          Moody's short-term ratings are designated Moody's Investment Grade as
     MIG 1 or VMIG 1 through MIG 4 or VMIG 4. As the name implies, when Moody's
     assigns a MIG or VMIG rating, all categories define an investment grade
     situation.
 
          MIG 1/VMIG 1. This designation denotes best quality. There is present
     strong protection by established cash flows, superior liquidity support or
     demonstrated broad-based access to the market for refinancing.
 
          MIG 2/VMIG 2. This designation denotes high quality. Margins of
     protection are ample although not so large as in the preceding group.
 
          MIG 3/VMIG 3. This designation denotes favorable quality. All security
     elements are accounted for but there is lacking the undeniable strength of
     the preceding grades. Liquidity and cash flow protection may be narrow and
     market access for refinancing is likely to be less well established.
 
          MIG 4/VMIG 4. This designation denotes adequate quality. Protection
     commonly regarded as required of an investment security is present and
     although not distinctly or predominantly speculative, there is specific
     risk.

          SG. This designation denotes speculative quality. Debt instruments in
     this category lack margins of protection.
 
     3.  TAX-EXEMPT COMMERCIAL PAPER
 
   
          Moody's short-term debt ratings are opinions of the ability of issuers
     to repay punctually promissory obligations not having an original maturity
     in excess of nine months. Moody's makes no representation that such
     obligations are exempt from registration under the Securities Act of 1933,
     nor does it represent that any specific note is a valid obligation of a
     rated issuer or issued in conformity with any applicable law.
    
 
   
          Moody's employs the following three designations, all judged to be
     investment grade, to indicate the relative repayment ability of rated
     issuers:
    
 
   
             Issuers rated Prime-1 (for related supporting institutions) have a
        superior capacity for repayment of short-term promissory obligations.
        Prime-1 repayment capacity will normally be evidenced by the following
        characteristics:
    
 
   
               - Leading market positions in well established industries.
    
 
   
               - High rates of return on funds employed.
    
 
   
               - Conservative capitalization structures with moderate reliance
                 on debt and ample asset protection.
    
 
   
               - Broad margins in earning coverage of fixed financial charges
                 and high internal cash generation.
    
 
   
               - Well established access to a range of financial markets and
                 assured sources of alternate liquidity.
    
 
   
             Issuers rated Prime-2 (or related supporting institutions) have a
        strong capacity for repayment of short-term promissory obligations. This
        will normally be evidenced by many of the characteristics cited above
        but to a lesser degree. Earnings trends and coverage ratios, while
        sound, will be more subject to variation. Capitalization
        characteristics, while still appropriate, may be more affected by
        external conditions. Ample alternate liquidity is maintained.
    
 
   
             Issuers rated Prime-3 (or related supporting institutions) have an
        acceptable capacity for repayment of short-term promissory obligations.
        The effects of industry characteristics and market composition may be
        more pronounced. Variability in earnings and profitability may result in
        changes in the level of debt protection measurements and the requirement
        for relatively high financial leverage. Adequate alternate liquidity is
        maintained.
    
 
   
             Issuers rated Not Prime do not fall within any of the Prime rating
        categories.

  Each of the trustees holds the same position with each of the funds in the
Fund Complex. As of December 31, 1996, there were 51 funds in the Fund Complex.
Each trustee who is not an affiliated person of VKAC, the Advisers, the
Distributor, ACCESS or Morgan Stanley (each a "Non-Affiliated Trustee") is
compensated by an annual retainer and meeting fees for services to the funds in
the Fund Complex. Each fund in the Fund Complex provides a deferred compensation
plan to its Non-Affiliated Trustees that allows trustees to defer receipt of
their compensation and earn a return on such deferred amounts based upon the
return of the common shares of the funds in the Fund Complex as more fully
described below. Each fund in the Fund Complex also provides a retirement plan
to its Non-Affiliated Trustees that provides Non-Affiliated Trustees with
compensation after retirement, provided that certain eligibility requirements
are met as more fully described below.
    
 
   
  The compensation of each Non-Affiliated Trustee from each fund in the Fund
Complex advised by Advisory Corp. (each a "VK Fund" and collectively the "VK
Funds") includes an annual retainer in an amount equal to $2,500 per calendar
year, due in four quarterly installments on the first business day of each
calendar quarter. Each Non-Affiliated Trustee receives a per meeting fee from
each VK Fund in the amount of $125 per regular quarterly meeting attended by the
Non-Affiliated Trustee, due on the date of such meeting, plus reasonable
expenses incurred by the Non-Affiliated Trustee in connection with his or her
services as a trustee. Each Non-Affiliated Trustee receives a per meeting fee
from each VK Fund in the amount of $125 per special meeting attended by the
Non-Affiliated Trustee, due on the date of such meeting, plus reasonable
expenses incurred by the Non-Affiliated Trustee in connection with his or her
services as a trustee, provided that no compensation will be paid in connection
with certain telephonic special meetings.
    
 
   
  The compensation of each Non-Affiliated Trustee from the funds in the Fund
Complex advised by Asset Management (each an "AC Fund" or collectively the "AC
Funds") includes an annual retainer in an amount equal to $35,000 per calendar
year, due in four quarterly installments on the first business day of each
calendar quarter. The AC Funds pay each Non-Affiliated Trustee a per meeting fee
in the amount of $2,000 per regular quarterly meeting attended by the
Non-Affiliated Trustee, due on the date of such meeting, plus reasonable
expenses incurred by the Non-Affiliated Trustee in connection with his or her
services as a trustee. Payment of the annual retainer and the regular meeting
fee is allocated among the AC Funds (i) 50% on the basis of the relative net
assets of each AC Fund to the aggregate net assets of all the AC Funds and (ii)
50% equally to each AC Fund, in each case as of the last business day of the
preceding calendar quarter. Each AC Fund which is the subject of a special
meeting of the trustees generally pays each Non-Affiliated Trustee a per meeting
fee in the amount of $125 per special meeting attended by the Non-Affiliated
Trustee, due on the date of such meeting, plus reasonable expenses incurred by
the Non-Affiliated Trustee in connection with his or her services as a trustee,
provided that no compensation will be paid in connection with certain telephonic
special meetings.
    
 
   
  The trustees approved an aggregate compensation cap with respect to funds in
the Fund Complex of $84,000 per Non-Affiliated Trustee per year (excluding any
retirement benefits) for the period July 22, 1995 through December 31, 1996,
subject to the net assets and the number of funds in the Fund Complex as of July
21, 1995 and certain other exceptions. For the calendar year ended December 31,
1996, certain trustees received aggregate compensation from the funds in the
Fund Complex over $84,000 due to compensation received but not subject to the
cap, including compensation from new funds added to the Fund Complex after July
22, 1995 and certain special meetings in 1996. In addition, each of Advisory
Corp. or Asset Management, as the case may be, agreed to reimburse each fund in
the Fund Complex through December 31, 1996 for any increase in the aggregate
trustee's compensation over the aggregate compensation paid by such fund in its
1994 fiscal year, provided that if a fund did not exist for the entire 1994
fiscal year appropriate adjustments will be made.
    
 
   
  Each Non-Affiliated Trustee generally can elect to defer receipt of all or a
portion of the compensation earned by such Non-Affiliated Trustee until
retirement. Amounts deferred are retained by the Fund and earn a rate of return
determined by reference to the return on the common shares of such Fund or other
funds in the Fund Complex as selected by the respective Non-Affiliated Trustee,
with the same economic effect as if such Non-Affiliated Trustee had invested in
one or more funds in the Fund Complex. To the extent permitted by the 1940 Act,
the Fund may invest in securities of those funds selected by the Non-Affiliated
Trustees in

order to match the deferred compensation obligation. The deferred compensation
plan is not funded and obligations thereunder represent general unsecured claims
against the general assets of the Fund.
    
 
   
  Each fund in the Fund Complex has adopted a retirement plan. Under the Fund's
retirement plan, a Non-Affiliated Trustee who is receiving trustee's
compensation from the Fund prior to such Non-Affiliated Trustee's retirement,
has at least 10 years of service (including years of service prior to adoption
of the retirement plan) and retires at or after attaining the age of 60, is
eligible to receive a retirement benefit equal to $2,500 per year for each of
the ten years following such trustee's retirement from the Fund. Trustees
retiring prior to the age of 60 or with fewer than 10 years but more than 5
years of service may receive reduced retirement benefits from the Fund. Each
trustee has served as a member of the Board of Trustees since he or she was
first appointed or elected in the year set forth below. The retirement plan

*  Currently a member of the Board of Trustees. Mr. Phillip B. Rooney also is a
   current member of the Board of Trustees but is not included in the
   compensation table because he did not serve on the Board of Trustees or
   receive any compensation from the Trust prior to April 14, 1997. Messrs.
   McDonnell and Powell, also trustees of the Trust during all or a portion of
   the Trust's last fiscal year, are not included in the compensation table
   because they are affiliated persons of the Advisers and are not eligible for
   compensation or retirement benefits from the Trust.
    
 
   
(1) Persons not designated by an asterisk are not currently members of the Board
    of Trustees, but were members of the Board of Trustees during the Trust's
    most recently completed fiscal year. Messrs. Gaughan and Rees retired from
    the Board of Trustees on January 26, 1996 and January 29, 1996,
    respectively. Mr. Sheehan was removed from the Board of Trustees effective
    January 29, 1996. Messrs. Hilsman, Miller and Woodside retired from the
    Board of Trustees on December 31, 1996.
    
 
   
(2) The amounts shown in this column represent the aggregate compensation before
    deferral from all eight series of the Trust, including the Fund, with
    respect to the Trust's fiscal year ended December 31, 1996.

    The detail of aggregate compensation before deferral for each series,
    including the Fund, are shown in Table A below. Certain trustees deferred
    compensation from the Trust during the fiscal year ended December 31, 1996;
    the aggregate compensation deferred from all eight series of the Trust,
    including the Fund, is as follows: Mr. Branagan, $5,750; Mr. Gaughan,
    $3,750; Ms. Heagy, $15,000; Mr. Kennedy, $9,500; Mr. Miller, $20,000; Mr.
    Nelson, $20,000; Mr. Robinson, $18,000; and Mr. Whalen, $19,625. The details
    of amounts deferred for each series, including the Fund, are shown in Table
    B below. Amounts deferred are retained by the respective fund and earn a
    rate of return determined by reference to either the return on the common
    shares of such fund or other funds in the Fund Complex as selected by the
    respective Non-Affiliated Trustee, with the same economic effect as if such
    Non-Affiliated Trustee had invested in one or more funds in the Fund
    Complex. To the extent permitted by the 1940 Act, each fund may invest in
    securities of those funds selected by the Non-Affiliated Trustees in order
    to match the deferred compensation obligation. The cumulative deferred
    compensation (including interest) accrued with respect to each trustee from
    all eight series of the Trust, including the Fund, as of the Trust's fiscal
    year ended December 31, 1996 is as follows: Mr. Branagan, $5,678; Mr.
    Gaughan, $20,094; Ms. Heagy, $20,472; Mr. Kennedy, $47,294; Mr. Miller,
    $55,827; Mr. Nelson, $57,771; Mr. Robinson, $54,847; and Mr. Whalen,
    $49,269. The details of cumulative deferred compensation (including
    interest) for each series, including the Fund, are shown in Table C below.
    The deferred compensation plan is described above the Compensation Table.
    
 
   
(3) The amounts shown in this column represent the retirement benefits accrued
    by all eight series of the Trust, including the Fund, with respect to the
    Trust's fiscal year ended December 31, 1996. The details of retirement
    benefits accrued for each series, including the Fund, are shown in Table D
    below. The retirement plan is described above the Compensation Table.
    
 
   
(4) This is the estimated maximum annual benefits payable by the Trust in each
    year of the 10-year period commencing in the year of such trustee's
    retirement from the Trust. The estimated maximum annual benefit, except for
    trustees who have retired or are near retirement, is based upon $2,500 per
    series assuming: the trustee has 10 or more years of service on the Board of
    Trustees (including years of service prior to the adoption of the retirement
    plan) and retires at or after attaining the age of 60. Trustees retiring
    prior to the age of 60 or with fewer than 10 years of service for a series
    of the Trust may receive reduced retirement benefits from such series. The
    actual annual benefit may be less if the trustee is subject to the Fund
    Complex retirement benefit cap or if the trustee is not fully vested at the
    time of retirement. Each Non-Affiliated Trustee of the Board of Trustees has
    served as a member of the Board of Trustees since he or she was first
    appointed or elected in the year set forth in Table E below.
    
 
   
(5) The amounts shown in this column represent the aggregate compensation paid
    by all 51 of the investment companies in the Fund Complex as of December 31,
    1996 before deferral by the trustees under the deferred compensation plan.
    Certain trustees deferred all or a portion of their aggregate compensation
    from the Fund Complex during the calendar year ended December 31, 1996. The
    deferred compensation earns a rate of return determined by reference to the
    return on the shares of the funds in the Fund Complex as selected by the
    respective Non-Affiliated Trustee, with the same economic effect as if such
    Non-Affiliated Trustee had invested in one or more funds in the Fund
    Complex. To the extent permitted by the 1940 Act, the Fund may invest in
    securities of those investment companies selected by the Non-Affiliated
    Trustees in order to match the deferred compensation obligation. The
    trustees' Fund Complex compensation cap covered the period July 22, 1995
    through December 31, 1996. For the calendar year ended December 31, 1996,
    certain trustees received compensation over $84,000 in the aggregate due to
    compensation received but not subject to the cap, including compensation
    from new funds added to the Fund Complex after July 22, 1995 and certain
    special meetings in 1996. The Advisers and their affiliates also serve as
    investment adviser for other investment companies; however, with the
    exception of Messrs. McDonnell, Powell and Whalen, the trustees were not
    trustees of such investment companies. Combining the Fund Complex with other
    investment companies advised by the Advisers and their affiliates, Mr.
    Whalen received Total Compensation of $243,375 during the calendar year
    ended December 31, 1996.
    
 
   
  As of April 4, 1997, the trustees and officers of the Fund as a group owned
less than 1% of the shares of the Fund.

                     INVESTMENT ADVISORY AND OTHER SERVICES
    
 
   
  The Adviser is the Fund's investment adviser. The Adviser was incorporated as
a Delaware corporation in 1982 (and through December 31, 1987 transacted
business under the name of American Portfolio Advisory Service Inc.).
    
 
   
  The Adviser is a wholly-owned subsidiary of Van Kampen American Capital, Inc.
("VKAC"), which is a wholly-owned subsidiary of VK/AC Holding, Inc. VK/AC
Holding, Inc. is a wholly-owned subsidiary of MSAM Holdings II, Inc. which, in
turn, is a wholly-owned subsidiary of Morgan Stanley Group Inc. The principal
office of the Fund, the Adviser, the Distributor and VKAC is located at One
Parkview Plaza, Oakbrook Terrace, Illinois 60181.
    
 
   
  Morgan Stanley Group Inc. and various of its directly or indirectly owned
subsidiaries, including Morgan Stanley & Co. Incorporated, a registered
broker-dealer and investment adviser, and Morgan Stanley International, are
engaged in a wide range of financial services. Their principal businesses
include securities underwriting, distribution and trading; merger, acquisition,
restructuring and other corporate finance advisory activities; merchant banking;
stock brokerage and research services; asset management; trading of futures,
options, foreign exchange, commodities and swaps (involving foreign exchange,
commodities, indices and interest rates); real estate advice, financing and

  On February 5, 1997, Morgan Stanley Group Inc. and Dean Witter, Discover & Co.
announced that they had entered into an Agreement and Plan of Merger to form
Morgan Stanley, Dean Witter, Discover & Co. Subject to certain conditions being
met, it is currently anticipated that the transaction will close in mid-1997.

  Dean Witter, Discover & Co. is a financial services company with three major
businesses; full service brokerage, credit services and asset management.
    
 
   
  The investment advisory agreement provides that the Adviser will supply
investment research and portfolio management, including the selection of
securities for the Fund to purchase. The Adviser also administers the business
affairs of the Fund, furnishes offices, necessary facilities and equipment,
provides administrative services, and permits its officers and employees to
serve without compensation as officers of the Fund and trustees of the Trust if
duly elected to such positions.
    
 
  The agreement provides that the Adviser shall not be liable for any error of
judgment or of law, or for any loss suffered by the Fund in connection with the
matters to which the agreement relates, except a loss resulting from willful
misfeasance, bad faith, or gross negligence on the part of the Adviser in the
performance of its obligations and duties, or by reason of its reckless
disregard of its obligations and duties under the agreement.
 
  The Adviser's activities are subject to the review and supervision of the
Board of Trustees of the Trust, of which the Fund is a series, to whom the
Adviser renders periodic reports of the Fund's investment activities.
 
  The investment advisory agreement for the Fund will continue in effect from
year to year if specifically approved by the Trustees of the Trust, of which the
Fund is a separate series (or by the Fund's shareholders), and by the
disinterested trustees in compliance with the requirements of the 1940 Act. The
agreement may be terminated without penalty upon 60 days' written notice by
either party thereto and will automatically terminate in the event of
assignment.
 
  The investment advisory agreement specifies that the Adviser will reimburse
the Fund for annual expenses of the Fund which exceed the most stringent limit
prescribed by any state in which the Fund's shares are offered for sale.
Currently, the most stringent limit in any state would require such
reimbursement to the extent that aggregate operating expenses of the Fund
(excluding interest, taxes and other expenses which may be excludable under
applicable state law) exceed in any fiscal year 2 1/2% of the average annual net
assets of the Fund up to $30 million, 2% of the average annual net assets of the
Fund of the next $70 million, and 1 1/2% of the remaining average annual net
assets of the Fund. In addition to making any required reimbursements, the
Adviser may in its discretion, but is not obligated to, waive all or any portion
of its fee or assume all or any portion of the expenses of the Fund.
 
   
  For the years ended December 31, 1996, 1995 and 1994, the Fund paid advisory
expenses of $4,825,272, $3,765,225 and $3,475,616, respectively.
    
 
OTHER AGREEMENTS
 
   
  ACCOUNTING SERVICES AGREEMENT.  The Fund has entered into an accounting
services agreement pursuant to which the Adviser provides accounting services
supplementary to those provided by the Custodian. Such services are expected to
enable the Fund to more closely monitor and maintain its accounts and records.
The Fund shares together with the other Van Kampen American Capital mutual funds
in the cost of providing such services, with 25% of such costs shared
proportionately based on the number of outstanding classes of securities per
fund and with the remaining 75 percent of such cost being paid by the Fund and
such other Van Kampen American Capital funds based proportionally on their
respective net assets.
    
 
   
  For the years ended December 31, 1996, 1995 and 1994, the Fund paid expenses
of approximately $80,200, $51,800 and $18,250, respectively, representing the
Adviser's cost of providing accounting services.
    
 
   
  LEGAL SERVICES AGREEMENT.  The Fund and each of the other Van Kampen American
Capital funds advised by the Adviser and distributed by the Distributor have
entered into Legal Services Agreements pursuant to which Van Kampen American
Capital provides legal services, including without limitation: accurate
maintenance of the funds' minute books and records, preparation and oversight of
the funds' regulatory reports, and other information provided to shareholders,
as well as responding to day-to-day legal issues on behalf of the funds. Payment
by the Fund for such services is made on a cost basis for the salary and salary
related benefits, including but not limited to bonuses, group insurances and
other regular wages for the employment of personnel, as well as overhead and the
expenses related to the office space and the equipment necessary to render the
legal services. Other funds distributed by the Distributor also receive legal
services

from Van Kampen American Capital. Of the total costs for legal services provided
to funds distributed by the Distributor, one half of such costs are allocated
equally to each fund and the remaining one half of such costs are allocated to
specific funds based on monthly time records.
 
   
  For the years ended December 31, 1996, 1995 and 1994, the Fund paid expenses
of approximately $27,900, $30,700 and $21,950, respectively, representing Van
Kampen American Capital's cost of providing legal services.
    
 
   
                     CUSTODIAN AND INDEPENDENT ACCOUNTANTS
    
 
  State Street Bank and Trust Company, 225 Franklin Street, P.O. Box 1713,
Boston, MA 02105-1713, is the custodian of the Fund and has custody of all
securities and cash of the Fund. The custodian, among other things, attends to
the collection of principal and income, and payment for and collection of
proceeds of securities bought and sold by the Fund.
 
   
  The independent accountants for the Fund are KPMG Peat Marwick LLP, Chicago,
Illinois. The selection of independent accountants will be subject to
ratification by the shareholders of the Fund at any annual meeting of
shareholders.
    
 
                PORTFOLIO TRANSACTIONS AND BROKERAGE ALLOCATION
 
  The Adviser will place orders for portfolio transactions for the Fund with
broker-dealer firms giving consideration to the quality, quantity and nature of
each firm's professional services. These services include execution, clearance
procedures, wire service quotations and statistical and other research
information provided to the Fund, or the Adviser, including quotations necessary
to determine the value of the Fund's net assets. Any research benefits derived
are available for all clients of the Adviser. Since statistical and other
research information is only supplementary to the research efforts of the
Adviser to the Fund and still must be analyzed and reviewed by its staff, the
receipt of research information is not expected to materially reduce its
expenses.
 
  If it is believed to be in the best interests of the Fund, the Adviser may
place portfolio transactions with brokers who provide the types of research
described above, even if it means the Fund will have to pay a higher commission
(or, if the broker's profit is part of the cost of the security, will have to
pay a higher price for the security), than would be the case if no weight were
given to the broker's furnishing of those research services. This will be done,
however, only if, in the opinion of the Fund's Adviser, the amount of additional
commission or increased cost is reasonable in relation to the value of such
services.
 
  In selecting among the firms believed to meet the criteria for handling a
particular transaction, the Adviser may take into consideration that certain
firms (i) provide market, statistical or other research information such as that
set forth above to the Fund or the Adviser, (ii) have sold or are selling shares
of the Fund and (iii) may select firms that are affiliated with the Fund, the
Adviser, or its distributor and other principal underwriters.
 
  If purchases or sales of securities of the Fund and of one or more other
investment companies or clients supervised by the Adviser are considered at or
about the same time, transactions in such securities will be allocated among the
several investment companies and clients in a manner deemed equitable to all by
the Adviser, taking into account the respective sizes of the Fund and other
investment companies and clients and the amount of securities to be purchased or
sold. Although it is possible that in some cases this procedure could have a
detrimental effect on the price or volume of the security as far as the Fund is
concerned, it is also possible that the ability to participate in volume
transactions and to negotiate lower brokerage commissions will be beneficial to
the Fund.
 
  While the Adviser will be primarily responsible for the placement of the
Fund's business, the policies and practices in this regard must be consistent
with the foregoing and will at all times be subject to review by the trustees of
the Trust, of which the Fund is a separate series.
 
  The trustees have adopted certain policies incorporating the standards of Rule
17e-1 issued by the SEC under the 1940 Act which requires that the commissions
paid to the Distributor and other affiliates of the Fund must be reasonable and
fair compared to the commissions, fees or other remuneration received or to be
 
                                      B-29
<PAGE>   606
 
received by other brokers in connection with comparable transactions involving
similar securities during a comparable period of time. The rule and procedures
also contain review requirements and require the Adviser to furnish reports to
the trustees and to maintain records in connection with such reviews. After
consideration of all factors deemed relevant, the trustees will consider from
time to time whether the advisory fee for the Fund will be reduced by all or a
portion of the brokerage commission given to affiliated brokers.
 
  State securities laws may differ from the interpretations of federal law
expressed herein, and banks and financial institutions may be required to
register as dealers pursuant to state law.
 
                             TAX STATUS OF THE FUND
 
   
  The Trust and any of its series, including the Fund, will be treated as
separate corporations for federal income tax purposes. The Fund intends to
qualify each year and to elect to be treated as a regulated investment company
under the Code. If the Fund so qualifies and distributes each year to its
shareholders at least 90% of its net investment income (including tax-exempt
interest, taxable income and net short-term capital gain, but not net capital
gains, which are the excess of long-term capital gains over net short-term
capital losses) in each year, it will not be required to pay federal income
taxes on any income distributed to shareholders. The Fund intends to distribute
at least the minimum amount of net investment income necessary to satisfy the
90% distribution requirement. The Fund will not be subject to federal income tax
on any net capital gains distributed to shareholders.
    
 
                                THE DISTRIBUTOR
 
   
  The Distributor offers one of the industry's broadest lines of investments --
encompassing mutual funds, closed-end funds and unit investment trusts -- and is
currently the nation's 5th largest broker-sold mutual fund group according to
Strategic Insight, July 1995. VKAC manages or supervises more than $57 billion
in mutual funds, closed-end funds and unit investment trusts -- assets which
have been entrusted to VKAC in more than 2 million investor accounts. VKAC has
one of the largest research teams (outside of the rating agencies) in the
country, with more than 80 analysts devoted to various specializations. Each of
our high yield analysts, based either in San Francisco, Chicago, Houston or
Boston, has the responsibility to cover a specific region of the country. This
regional focus enables each high yield analyst to provide more specialized
coverage of the market and alert the portfolio manager to issues of local
importance.
    
 
   
  Shares of the Fund are offered on a continuous basis through the Distributor.
The Distributor is a wholly owned subsidiary of Van Kampen American Capital,
Inc., which is a subsidiary of VK/AC Holding, Inc. MSAM Holdings II, Inc. which,
in turn, is a wholly-owned subsidiary of Morgan Stanley Group Inc. The principal
office of the Fund, the Adviser, the Distributor and VKAC is located at One
Parkview Plaza, Oakbrook Terrace, Illinois 60181.
    
 
   
  Morgan Stanley Group Inc. and various of its directly or indirectly owned
subsidiaries, including Morgan Stanley & Co. Incorporated, a registered
broker-dealer and investment adviser, and Morgan Stanley International, are
engaged in a wide range of financial services. Their principal businesses
include securities underwriting, distribution and trading; merger, acquisition,
restructuring and other corporate finance advisory activities; merchant banking;
stock brokerage and research services; asset management; trading of futures,
options, foreign exchange, commodities and swaps (involving foreign exchange,
commodities, indices and interest rates); real estate advice, financing and
investing; and global custody, securities clearance services and securities
lending.
    
 
   
  On February 5, 1997, Morgan Stanley Group Inc. and Dean Witter, Discover & Co.
announced that they had entered into an Agreement and Plan of Merger to form
Morgan Stanley, Dean Witter, Discover & Co. Subject to certain conditions being
met, it is currently anticipated that the transaction will close in mid-1997.
Thereafter, Van Kampen American Capital Asset Management, Inc. will be an
indirect subsidiary of Morgan Stanley, Dean Witter, Discover & Co.
    
 
   
  Dean Witter, Discover & Co. is a financial services company with three major
businesses; full service brokerage, credit services and asset management.

  Pursuant to a distribution agreement, the Distributor will purchase shares of
the Fund for resale to the public, either directly or through securities
dealers, and is obligated to purchase only those shares for which it has
received purchase orders. A discussion of how to purchase and redeem the Fund's
shares and how the Fund's shares are priced is contained in the Prospectus.
    
 
   
                         DISTRIBUTION AND SERVICE PLANS
    
 
  The Fund has adopted a distribution plan (the "Distribution Plan") with
respect to each class of its shares pursuant to Rule 12b-1 under the 1940 Act.
The Fund also has adopted a service plan (the "Service Plan") with respect to
each class of shares. The Distribution Plan and Service Plan sometimes are
referred to herein collectively as the "Plans". The Plans provide that the Fund
may spend a portion of the Fund's average daily net assets attributable to each
class of shares in connection with distribution of the respective class of
shares and in connection with the provision of ongoing services to shareholders
of such class, respectively. The Plans are being implemented through an
agreement (the "Distribution and Service Agreement") with the Distributor and
sub-agreements between the Distributor and members of the NASD who are acting as
securities dealers and NASD members or eligible non-members who are acting as
brokers or agents and similar agreements between the Fund and financial
intermediaries who are acting as brokers (collectively, "Selling Agreements")
that may provide for their customers or clients certain services or assistance,
which may include, but not be limited to, processing purchase and redemption
transactions, establishing and maintaining shareholder accounts regarding the
Fund, and such other services as may be agreed to from time to time and as may
be permitted by applicable statute, rule or regulation. Brokers, dealers and
financial intermediaries that have entered into sub-agreements with the
Distributor and sell shares of the Fund are referred to herein as "financial
intermediaries."
 
   
  Under the Distribution and Service Agreement and the Selling Agreements,
financial intermediaries that sold shares prior to July 1, 1987, or prior to the
beginning of the calendar quarter in which the Selling Agreement between the
Fund and such financial intermediary was approved by the Fund's Board of
Trustees (an "Implementation Date") are not eligible to receive compensation
pursuant to such Distribution and Service Agreement or Selling Agreement. To the
extent that there remain outstanding shares of the Fund that were purchased
prior to all Implementation Dates, the percentage of the total average daily net
asset value of a class of shares that may be utilized pursuant to the
Distribution and Service Agreement will be less than the maximum percentage
amount permissible with respect to such class of shares under the Distribution
and Service Agreement.
    
 
  The Distributor must submit quarterly reports to the Board of Trustees of the
Trust, of which the Fund is a series, setting forth separately by class of
shares all amounts paid under the Plans and the purposes for which such
expenditures were made, together with such other information as from time to
time is reasonably requested by the Trustees. The Plans provide that they will
continue in full force and effect from year to year so long as such continuance
is specifically approved by a vote of the Trustees, and also by a vote of the
disinterested Trustees, cast in person at a meeting called for the purpose of
voting on the Plans. Each of the Plans may not be amended to increase materially
the amount to be spent for the services described therein with respect to either
class of shares without approval by a vote of a majority of the outstanding
voting shares of such class, and all material amendments to either of the Plans
must be approved by the Trustees and also by the disinterested Trustees. Each of
the Plans may be terminated with respect to either class of shares at any time
by a vote of a majority of the disinterested Trustees or by a vote of a majority
of the outstanding voting shares of such class.
 
   
  For the fiscal year ended December 31, 1996, the Fund's aggregate expenses
under the Plans for Class A shares were $1,990,737 or 0.25% of the Class A
shares' average net assets. Such expenses were paid to reimburse the Distributor
for payments made to financial intermediaries for servicing Fund shareholders
and for administering the Plans. For the fiscal year ended December 31, 1996,
the Fund's aggregate expenses under the Plans for Class B shares were $2,084,477
or 1.00% of the Class B shares' average net assets. Such expenses were paid to
reimburse the Distributor for the following payments: $1,563,358 for commissions
and transaction fees paid to financial intermediaries in respect of sales of
Class B shares of the Fund and $521,119 for fees paid to financial
intermediaries for servicing Class B shareholders and administering the Plans.
For the fiscal year ended December 31, 1996, the Fund's aggregate expenses under
the Plans for Class C shares were
    
 
                                      B-31
<PAGE>   608
 
   
$119,847 or 1.00% of the Class C shares' average net assets. Such expenses were
paid to reimburse the Distributor for the following payments: $51,203 for
commissions and transaction fees paid to financial intermediaries in respect of
sales of Class C shares of the Fund and $68,644 for fees paid to financial
intermediaries for servicing Class C shareholders and administering the Plans.

                            PERFORMANCE INFORMATION
 
  From time to time marketing materials may provide a portfolio manager update,
an adviser update or discuss general economic conditions and outlooks. The
Fund's marketing materials may also show the Fund's asset class diversification,
top five sectors, ten largest holdings and other Fund asset structures, such as
duration, maturity, coupon, NAV, rating breakdown, AMT exposure and number of
issues in the portfolio. Materials may also mention how Van Kampen American
Capital believes the Fund compares relative to other Van Kampen American Capital
funds. Materials may also discuss the Dalbar Financial Services study from 1984
to 1994 which studied investor cash flow into and out of all types of mutual
funds. The ten year study found that investors who bought mutual fund shares and
held such shares outperformed investors who bought and sold. The Dalbar study
conclusions were consistent regardless of if shareholders purchased their funds
in direct or sales force distribution channels. The study showed that investors
working with a professional representative have tended over time to earn higher
returns than those who invested directly. The Fund will also be marketed on the
Internet.
 
  The Fund's yield quotation is determined on a monthly basis with respect to
the immediately preceding 30 day period, and yield is computed by dividing the
Fund's net investment income per share of a given class earned during such
period by the Fund's maximum offering price (including, with respect to the
Class A Shares, the maximum initial sales charge) per share of such class on the
last day of such period. The Fund's net investment income per share is
determined by taking the interest attributable to a given class of shares earned
by the Fund during the period, subtracting the expenses attributable to a given
class of shares accrued for the period (net of any reimbursements), and dividing
the result by the average daily number of the shares of each class outstanding
during the period that were entitled to receive dividends. The yield calculation
formula assumes net investment income is earned and reinvested at a constant
rate and annualized at the end of a six month period. Yield will be computed
separately for each class of shares. Class B Shares redeemed during the first
six years after their issuance and Class C Shares redeemed during the first year
after their issuance may be subject to a contingent deferred sales charge in a
maximum amount equal to 4% and 1%, respectively, of the lesser of the then
current net asset value of the shares redeemed or their initial purchase price
from the Fund. Yield quotations do not reflect the imposition of a contingent
deferred sales charge, and if any such contingent deferred sales charge imposed
at the time of redemption were reflected, it would reduce the performance
quoted.
 
  Tax-equivalent yield demonstrates the taxable yield required to produce an
after-tax yield equivalent to that of the Fund's yield. The Fund's
tax-equivalent yield quotation for a 30 day period as described above is
computed by dividing that portion of the yield of the Fund (as computed above)
which is tax-exempt by a percentage equal to 100% minus a stated percentage
income tax rate and adding the result to that portion of the Fund's yield, if
any, that is not tax-exempt.
 
  The Fund calculates average compounded total return by determining the
redemption value (less any applicable contingent deferred sales charge) at the
end of specified periods (after adding back all dividends and other
distributions made during the period) of a $1,000 investment in a given class of
shares of the Fund (less the maximum sales charge, if any) at the beginning of
the period, annualizing the increase or decrease over the specified period with
respect to such initial investment and expressing the result as a percentage.
Average compounded total return will be computed separately for each class of
shares.
 
  Total return figures utilized by the Fund are based on historical performance
and are not intended to indicate future performance. Total return and net asset
value per share of a given class can be expected to
 
                                      B-32
<PAGE>   609
 
fluctuate over time, and accordingly upon redemption a shareholder's shares may
be worth more or less than their original cost.
 
  The Fund may, in supplemental sales literature, advertise non-standardized
total return figures representing the cumulative, non-annualized total return of
each class of shares of the Fund from a given date to a subsequent given date.
Cumulative total return is calculated by measuring the value of an initial
investment in a given class of shares of the Fund at a given time, including or
excluding any applicable sales charge as indicated, determining the value of all
subsequent reinvested distributions, and dividing the net change in the value of
the investment as of the end of the period by the amount of the initial
investment and expressing the result as a percentage. Non-standardized total
return will be calculated separately for each class of shares. Non-standardized
total return calculations do not reflect the imposition of a contingent deferred
sales charge, and if any such contingent deferred sales charge with respect to
the CDSC imposed at the time of redemption were reflected, it would reduce the
performance quoted.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
The Board of Trustees and Shareholders of
Van Kampen American Capital Municipal Income Fund:
 
We have audited the accompanying statement of assets and liabilities of Van
Kampen American Capital Municipal Income Fund (the "Fund"), including the
portfolio of investments, as of December 31, 1996, and the related statement of
operations for the year then ended, the statement of changes in net assets for
each of the two years in the period then ended, and the financial highlights for
each of the periods presented. These financial statements and financial
highlights are the responsibility of the Fund's management. Our responsibility
is to express an opinion on these financial statements and financial highlights
based on our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of
December 31, 1996, by correspondence with the custodian and brokers. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.
 
    In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of Van
Kampen American Capital Municipal Income Fund as of December 31, 1996, the
results of its operations for the year then ended, the changes in its net assets
for each of the two years in the period then ended, and the financial highlights
for each of the periods presented, in conformity with generally accepted
accounting principles.

1. SIGNIFICANT ACCOUNTING POLICIES
 
Van Kampen American Capital Municipal Income Fund (the "Fund") is organized as a
series of the Van Kampen American Capital Tax Free Trust, a Delaware business
trust, and is registered as a diversified open-end management investment company
under the Investment Company Act of 1940, as amended. The Fund's investment
objective is to provide a high level of current income exempt from federal
income tax, consistent with preservation of capital. The Fund commenced
investment operations on August 1, 1990. The distribution of the Fund's Class B
and Class C shares commenced on August 24, 1992 and August 13, 1993,
respectively. On July 6, 1995, all Class D shareholders redeemed their shares
and the class was eliminated. The Fund will no longer offer Class D shares.
 
       The following is a summary of significant accounting policies
consistently followed by the Fund in the preparation of its financial
statements. The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
A. SECURITY VALUATION--Investments are stated at value using market quotations
or, if such valuations are not available, estimates obtained from yield data
relating to instruments or securities with similar characteristics in accordance
with procedures established in good faith by the Board of Trustees. Short-term
securities with remaining maturities of 60 days or less are valued at amortized
cost.
 
B. SECURITY TRANSACTIONS--Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis. The
Fund may purchase and sell securities on a "when issued" or "delayed delivery"
basis, with settlement to occur at a later date. The value of the security so
purchased is subject to market fluctuations during this period. The Fund will
maintain, in a segregated account with its custodian, assets having an aggregate
value at least equal to the amount of the when issued or delayed delivery
purchase commitments until payment is made.
 
C. INVESTMENT INCOME--Interest income is recorded on an accrual basis. Bond
premium and original issue discount are amortized over the expected life of each
applicable security.
 
D. FEDERAL INCOME TAXES--It is the Fund's policy to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no provision for federal income taxes is required.
 
       The Fund intends to utilize provisions of the federal income tax laws
which allow it to carry a realized capital loss forward for eight years
following the year of the loss and offset such losses against any future
realized capital gains. At December 31, 1996, the Fund had an accumulated
capital loss carryforward for tax purposes of $28,118,805 which expires between
December 31, 2002 and December 31, 2003. Net realized gains or losses differ for
financial reporting and tax purposes primarily as a result of the deferral of
losses for tax purposes resulting from wash sale transactions, gains or losses
recognized for tax purposes on open option and futures positions and the
capitalization for tax purposes of reorganization and restructuring costs.
 
                                       B-54

                               December 31, 1996
- --------------------------------------------------------------------------------
 
E. DISTRIBUTION OF INCOME AND GAINS--The Fund declares daily and pays monthly
dividends from net investment income. Net realized gains, if any, are
distributed annually. Distributions from net realized gains for book purposes
may include short-term capital gains, which are included as ordinary income for
tax purposes.
 
       For the year ended December 31, 1996, 98.77% of the income distributions
made by the Fund were exempt from federal income taxes.
 
       Due to inherent differences in the recognition of interest income under
generally accepted accounting principles and federal income tax purposes, for
those securities which the Fund has placed on non-accrual status, the amount of
distributable net investment income may differ between book and federal income
tax purposes for a particular period. These differences are temporary in nature,
but may result in book basis distribution in excess of net investment income for
certain periods. Additionally, permanent book and tax basis differences relating
to the recognition of certain expenses which are not deductible for tax purposes
totaling $150,677 were reclassified from accumulated undistributed net
investment income to capital.
 
2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES
 
Under the terms of the Fund's Investment Advisory Agreement, Van Kampen American
Capital Investment Advisory Corp. (the "Adviser") will provide investment advice
and facilities to the Fund for an annual fee payable monthly as follows:

</TABLE>
 
       Certain legal expenses are paid to Skadden, Arps, Slate, Meagher & Flom
(Illinois), counsel to the Fund, of which a trustee of the Fund is an affiliated
person.
 
       For the year ended December 31, 1996, the Fund recognized expenses of
approximately $108,100 representing Van Kampen American Capital Distributors,
Inc.'s or its affiliates' (collectively "VKAC") cost of providing accounting,
cash management and legal services to the Fund.
 
       ACCESS Investor Services, Inc. ("ACCESS"), an affiliate of the Adviser,
serves as the shareholder servicing agent of the Fund. For the year ended
December 31, 1996, the Fund recognized expenses of approximately $892,000,
representing ACCESS' cost of providing transfer agency and shareholder services
plus a profit.
 
       Certain officers and trustees of the Fund are also officers and directors
of VKAC. The Fund does not compensate its officers or trustees who are officers
of VKAC. For the year ended December 31, 1996, the Adviser reimbursed the Fund
for certain trustees' compensation in connection with the July, 1995 increase in
the number of trustees of the Fund.
 
       The Fund has implemented deferred compensation and retirement plans for
its trustees. Under the deferred compensation plan, trustees may elect to defer
all or a portion of their compensation to a later date. The retirement plan
covers those trustees who are not officers of VKAC.
 
       At December 31, 1996, VKAC owned 6,894, 33 and 32 shares of Classes A, B
and C, respectively.
 
3. CAPITAL TRANSACTIONS
 
The Fund has outstanding three classes of shares of beneficial interest, Classes
A, B and C each with a par value of $.01 per share. There are an unlimited
number of shares of each class authorized.

- --------------------------------------------------------------------------------
 
       For the year ended December 31, 1996, VKAC, as Distributor for the Fund,
received commissions on sales of the Fund's Class A shares of approximately
$122,900 and CDSC on redeemed shares of approximately $506,000. Sales charges do
not represent expenses of the Fund.
 
       On September 22, 1995, the Fund acquired all of the assets and
liabilities of the Van Kampen American Capital Municipal Bond Fund (the "AC
Fund"), through a tax free reorganization approved by AC Fund shareholders on
September 21, 1995. The Fund issued 20,054,672, 2,774,312 and 471,489 shares of
Classes A, B and C valued at $301,019,346, $41,842,606 and $7,076,761,
respectively, in exchange for AC Fund's net assets. Shares issued in connection
with this reorganization are included in common share sales for the year ended
December 31, 1995. Combined net assets on the date of acquisition were
$1,027,309,801.
 
       On October 25, 1996, the Fund acquired all of the assets and liabilities
of the Van Kampen American Capital Texas Tax Free Income Fund (the "TX Fund"),
through a tax free reorganization approved by TX Fund shareholders on October
15, 1996. The Fund issued 605,902, 421,195 and 53,444 shares of Classes A, B and
C valued at $9,179,415, $6,381,107 and $809,140, respectively, in exchange for
TX Fund's net assets. Shares issued in connection with this reorganization are
included in common share sales for the current period. Combined net assets on
the day of acquisition were $1,003,018,474.
 
4. INVESTMENT TRANSACTIONS
 
During the period, the cost of purchases and proceeds from sales of investments,
excluding short-term investments, were $744,315,333 and $775,600,106,
respectively.
 
5. DERIVATIVE FINANCIAL INSTRUMENTS
 
A derivative financial instrument in very general terms refers to a security
whose value is "derived" from the value of an underlying asset, reference rate
or index.
 
       The Fund has a variety of reasons to use derivative instruments, such as
to attempt to protect the Fund against possible changes in the market value of
its portfolio and to manage the portfolio's effective yield, maturity and
duration. All of the Fund's portfolio holdings, including derivative
instruments, are marked to market each day with the change in value reflected in
the unrealized appreciation/depreciation on investments. Upon disposition, a
realized gain or loss is recognized accordingly, except when exercising an
option contract or taking delivery of a security underlying a futures contract.
In these instances the recognition of gain or loss is postponed until the
disposal of the security underlying the option or futures contract.
 
       Summarized below are the specific types of derivative financial
instruments used by the Fund.
 
A. OPTION CONTRACTS--An option contract gives the buyer the right, but not the
obligation to buy (call) or sell (put) an underlying item at a fixed exercise
price during a specified period. These contracts are generally used by the Fund
to manage the portfolio's effective maturity and duration.

B. FUTURES CONTRACTS--A futures contract is an agreement involving the delivery
of a particular asset on a specified future date at an agreed upon price. The
Fund generally invests in futures on U.S. Treasury Bonds and the Municipal Bond
Index and typically closes the contract prior to the delivery date. These
contracts are generally used to manage the portfolio's effective maturity and
duration.
 
       Upon entering into futures contracts, the Fund maintains, in a segregated
account with its custodian, securities with a value equal to its obligation
under the futures contracts. During the period the futures contract is open,
payments are received from or made to the broker based upon changes in the value
of the contract (the variation margin).
 
       Transactions in futures contracts for the year ended December 31, 1996,
were as follows:

C. INDEXED SECURITIES--These instruments are identified in the portfolio of
investments. The price of these securities may be more volatile than the price
of a comparable fixed rate security.
 
       An Inverse Floating security is one where the coupon is inversely indexed
to a short-term floating interest rate multiplied by a specified factor. As the
floating rate rises, the coupon is reduced. Conversely, as the floating rate
declines, the coupon is increased. These instruments are typically used by the
Fund to enhance the yield of the portfolio.
 
       An Embedded Swap security includes a swap component such that the fixed
coupon component of the underlying bond is adjusted by the difference between
the securities fixed swap rate and the floating swap index. These instruments
are typically used by the Fund to enhance the yield of the portfolio.
 
6. DISTRIBUTION AND SERVICE PLANS
 
The Fund and its shareholders have adopted a distribution plan pursuant to Rule
12b-1 under the Investment Company Act of 1940 and a service plan (collectively
the "Plans"). The Plans govern payments for the distribution of the Fund's
shares, ongoing shareholder services and maintenance of shareholder accounts.
 
       Annual fees under the Plans of up to .25% for Class A net assets and
1.00% each for Class B and Class C net assets are accrued daily. Included in
these fees for the year ended December 31, 1996, are payments to VKAC of
approximately $1,584,600.

                             THE FUND AND THE TRUST
 
   
  Van Kampen American Capital Intermediate Term Municipal Income Fund (the
"Fund") is a separate series of the Trust, an open-end diversified management
investment company. At present, the Fund, Van Kampen American Capital Municipal
Income Fund, Van Kampen American Capital Insured Tax Free Income Fund, Van
Kampen American Capital Tax Free High Income Fund, Van Kampen American Capital
California Insured Tax Free Fund, Van Kampen American Capital Florida Insured
Tax Free Income Fund, Van Kampen American Capital New Jersey Tax Free Income
Fund and Van Kampen American Capital New York Tax Free Income Fund have been
organized as series of the Trust and have commenced investment operations. Van
Kampen American Capital California Tax Free Income Fund, Van Kampen American
Capital Michigan Tax Free Income Fund, Van Kampen American Capital Missouri Tax
Free Income Fund and Van Kampen American Capital Ohio Tax Free Income Fund have
been organized as series of the Trust but have not commenced investment
operations. Other series may be organized and offered in the future.
    
 
   
  The Trust is an unincorporated business trust established under the laws of
the state of Delaware by an Agreement and Declaration of Trust dated as of May
10, 1995 (the "Declaration of Trust"). The Declaration of Trust permits the
Trustees to create one or more separate investment portfolios and issue a series
of shares for each portfolio. The Trustees can further sub-divide each series of
shares into one or more classes of shares for each portfolio. The Trust can
issue an unlimited number of shares, $0.01 per share (prior to July 31, 1995,
the shares had no par value). Each share represents an equal proportionate
interest in the assets of the series with each other share in such series and no
interest in any other series. No series is subject to the liabilities of any
other series. The Declaration of Trust provides that shareholders are not liable
for any liabilities of the Trust or any of its series, requires inclusion of a
clause to that effect in every agreement entered into by the Trust or any of its
series and indemnifies shareholders against any such liability. The Fund was
originally organized under the name Van Kampen Merritt Limited Term Municipal
Income Fund as a sub-trust of Van Kampen Merritt Tax Free Fund, a Massachusetts
business trust. The Fund was reorganized as a series of the Trust on July 31,
1995 as Van Kampen American Capital Limited Term Municipal Income Fund and was
renamed Van Kampen American Capital Intermediate Term Municipal Income Fund as
of January 26, 1996.
    
 
  Shares of the Trust entitle their holders to one vote per share; however,
separate votes are taken by each series on matters affecting an individual
series. For example, a change in investment policy for a series would be voted
upon by shareholders of only the series involved. Except as described in the
Prospectus, shares do not have cumulative voting rights, preemptive rights or
any conversion or exchange rights. The Trust does not contemplate holding
regular meetings of shareholders to elect Trustees or otherwise. However, the
holders of 10% or more of the outstanding shares may by written request require
a meeting to consider the removal of Trustees by a vote of two-thirds of the
shares then outstanding cast in person or by proxy at such meeting.
 
  The Trustees may amend the Declaration of Trust (including with respect to any
series) in any manner without shareholder approval, except that the Trustees may
not adopt any amendment adversely affecting the rights of shareholders of any
series without approval by a majority of the shares of each affected series
present at a meeting of shareholders (or such higher vote as may be required by
the Investment Company Act of 1940, as amended (the "1940 Act") or other
applicable law) and except that the Trustees cannot amend the Declaration of
Trust to impose any liability on shareholders, make any assessment on shares or
impose liabilities on the Trustees without approval from each affected
shareholder or Trustee, as the case may be.
 
  Statements contained in this Statement of Additional Information as to the
contents of any contract or other document referred to are not necessarily
complete, and, in each instance, reference is made to the copy of such contract
or other document filed as an exhibit to the Registration Statement of which
this Statement of Additional Information forms a part, each such statement being
qualified in all respects by such reference.
 
                      INVESTMENT POLICIES AND RESTRICTIONS
 
  The investment objective of the Fund is set forth in the Prospectus under the
caption "Investment Objective and Policies." There can be no assurance that the
Fund will achieve its investment objective.
 
  Fundamental investment restrictions limiting the investments of the Fund
provide that the Fund may not:
 
   1. With respect to 75% of its total assets, purchase any securities (other
      than obligations guaranteed by the United States Government or by its
      agencies or instrumentalities), if, as a result, more than 5% of the
 
                                       B-2
<PAGE>   639
 
   
      Fund's total assets (determined at the time of investment) would then be
      invested in securities of a single issuer or, if, as a result, the Fund
      would hold more than 10% of the outstanding voting securities of an
      issuer, except that the Fund may purchase securities of other investment
      companies to the extent permitted by (i) the 1940 Act, as amended from
      time to time, (ii) the rules and regulations promulgated by the SEC under
      the 1940 Act, as amended from time to time, or (iii) an exemption or other
      relief from the provisions of the 1940 Act.
    
 
   
   2. Invest more than 25% of its assets in a single industry; however, as
      described in the Prospectus, the Fund may from time to time invest more
      than 25% of its assets in a particular segment of the municipal securities
      market; however, the Fund will not invest more than 25% of its assets in
      industrial development bonds in a single industry, except that the Fund
      may purchase securities of other investment companies to the extent
      permitted by (i) the 1940 Act, as amended from time to time, (ii) the
      rules and regulations promulgated by the SEC under the 1940 Act, as
      amended from time to time, or (iii) an exemption or other relief from the
      provisions of the 1940 Act.
    
 
   3. Borrow money, except from banks for temporary purposes and then in amounts
      not in excess of 5% of the total asset value of the Fund, or mortgage,
      pledge, or hypothecate any assets except in connection with a borrowing
      and in amounts not in excess of 10% of the total asset value of the Fund.
      Borrowings may not be made for investment leverage, but only to enable the
      Fund to satisfy redemption requests where liquidation of portfolio
      securities is considered disadvantageous or inconvenient. In this
      connection, the Fund will not purchase portfolio securities during any
      period that such borrowings exceed 5% of the total asset value of the
      Fund. Notwithstanding this investment restriction, the Fund may enter into
      when issued and delayed delivery transactions as described in the
      Prospectus.
 
   4. Make loans of money or property, except to the extent the obligations the
      Fund may invest in are considered to be loans and except to the extent
      that the Fund may lend money or property in connection with maintenance of
      the value of or the Fund's interest with respect to the securities owned
      by the Fund.
 
   5. Buy any securities "on margin." Neither the deposit of initial or
      maintenance margin in connection with Strategic Transactions nor short
      term credits as may be necessary for the clearance of transactions is
      considered the purchase of a security on margin.
 
   6. Sell any securities "short," write, purchase or sell puts, calls or
      combinations thereof, or purchase or sell interest rate or other financial
      futures or index contracts or related options, except in connection with
      Strategic Transactions in accordance with the requirements of the SEC and
      the Commodity Futures Trading Commission.
 
   7. Act as an underwriter of securities, except to the extent the Fund may be
      deemed to be an underwriter in connection with the sale of securities held
      in its portfolio.
 
   
   8. Make investments for the purpose of exercising control or participation in
      management, except to the extent that exercise by the Fund of its rights
      under agreements related to municipal securities would be deemed to
      constitute such control or participation, except that the Fund may
      purchase securities of other investment companies to the extent permitted
      by (i) the 1940 Act, as amended from time to time, (ii) the rules and
      regulations promulgated by the SEC under the 1940 Act, as amended from
      time to time, or (iii) an exemption or other relief from the provisions of
      the 1940 Act.
    
 
   
   9. Invest in securities issued by other investment companies except as part
      of a merger, reorganization or other acquisition and extent permitted by
      (i) the 1940 Act, as amended from time to time, (ii) the rules and
      regulations promulgated by the SEC under the 1940 Act, as amended from
      time to time, or (iii) an exemption or other relief from the provisions of
      the 1940 Act.
    
 
  10. Invest in oil, gas or mineral leases or in equity interests in oil, gas,
      or other mineral exploration or development programs except pursuant to
      the exercise by the Fund of its rights under agreements relating to
      municipal securities.
 
                                       B-3
<PAGE>   640
 
  11. Purchase or sell real estate, commodities or commodity contracts, except
      to the extent that the securities that the Fund may invest in are
      considered to be interests in real estate, commodities or commodity
      contracts or to the extent the Fund exercises its rights under agreements
      relating to such municipal securities (in which case the Fund may
      liquidate real estate acquired as a result of a default on a mortgage),
      and except to the extent that Strategic Transactions the Fund may engage
      in are considered to be commodities or commodities contracts.
 
  The Fund may not change any of these investment restrictions nor any other
fundamental policy as they apply to the Fund without the approval of the lesser
of (i) more than 50% of the Fund's outstanding shares or (ii) 67% of the Fund's
shares present at a meeting at which the holders of more than 50% of the
outstanding shares are present in person or by proxy. As long as the percentage
restrictions described above are satisfied at the time of the investment or
borrowing, the Fund will be considered to have abided by those restrictions even
if, at a later time, a change in values or net assets causes an increase or
decrease in percentage beyond that allowed.
 
  The Fund generally will not engage in the trading of securities for the
purpose of realizing short-term profits, but it will adjust its portfolio as
deemed advisable in view of prevailing or anticipated market conditions to
accomplish the Fund's investment objectives. For example, the Fund may sell
portfolio securities in anticipation of a movement in interest rates. Frequency
of portfolio turnover will not be a limiting factor if the Fund considers it
advantageous to purchase or sell securities. The Fund may have annual portfolio
turnover rates in excess of 100%. Portfolio turnover will be calculated by
dividing the lesser of purchases or sales of portfolio securities by the monthly
average value of the securities in the portfolio during the year. Securities,
including options, whose maturity or expiration date at the time of acquisition
were one year or less will be excluded from such calculation.
 
  Under current market conditions, the Fund anticipates that it will limit the
dollar-weighted average life of its portfolio to between three and ten years.
There is no limitation with respect to the anticipated life or stated maturity
of individual municipal securities in the Fund's portfolio. The weighted average
life of a security is generally a measure of the anticipated period until the
principal amount of the obligation is repaid, taking into account such factors
as scheduled amortization, anticipated prepayments, put, call or redemption
features and market conditions.
 
  The Fund does not intend to lend its portfolio securities.
 
                      ADDITIONAL INVESTMENT CONSIDERATIONS
 
MUNICIPAL SECURITIES
 
  Municipal securities include long-term obligations, which are often called
municipal bonds, as well as shorter term municipal notes, municipal leases, and
tax-exempt commercial paper. Under normal market conditions, longer term
municipal securities generally provide a higher yield than shorter term
municipal securities, and therefore the Fund generally expects to be invested
primarily in longer term municipal securities. The Fund will, however, invest in
shorter term municipal securities when yields are greater than yields available
on longer term municipal securities, for temporary defensive purposes and when
redemption requests are expected. The two principal classifications of municipal
bonds are "general obligation" and "revenue" or "special obligation" bonds,
which include "industrial revenue bonds." General obligation bonds are secured
by the issuer's pledge of its faith, credit, and taxing power for the payment of
principal and interest. Revenue or special obligation bonds are payable only
from the revenues derived from a particular facility or class of facilities or,
in some cases, from the proceeds of a special tax or other specific revenue
source such as from the user of the facility being financed.
 
  Also included within the general category of municipal securities are
participations in lease obligations or installment purchase contract obligations
(hereinafter collectively called "lease obligations") of municipal authorities
of entities used to finance the acquisition of equipment and facilities.
Although lease obligations do not constitute general obligations of the
municipality for which the municipality's taxing power is pledged, a lease
obligation is ordinarily backed by the municipality's covenant to budget for,
appropriate and make the payments due under the lease obligation. However,
certain lease obligations contain "non-appropriation"
 
                                       B-4
<PAGE>   641
 
clauses which provide that the municipality has no obligation to make lease or
installment purchase payments in future years unless money is appropriated for
such purpose on a yearly basis. A risk exists that the municipality will not, or
will be unable to, appropriate money in the future in the event of political
changes, changes in the economic viability of the project, general economic
changes or for other reasons. In addition to the "non-appropriation" risk, these
securities represent a relatively new type of financing that has not yet
developed the depth of marketability associated with more conventional bonds.
Although "non-appropriation" lease obligations are often secured by an
assignment of the lessee's interest in the leased property, management and/or
disposition of the property in the event of foreclosure could be costly, time
consuming and result in unsatisfactory recoupment of the Fund's original
investment. There is no limitation on the percentage of the Fund's assets that
may be invested in "non-appropriation" lease obligations. In evaluating such
lease obligations, the Adviser will consider such factors as it deems
appropriate, which factors may include (a) whether the lease can be cancelled,
(b) the ability of the lease obligee to direct the sale of the underlying
assets, (c) the general creditworthiness of the lease obligor, (d) the
likelihood that the municipality will discontinue appropriating funding for the
leased property in the event such property is no longer considered essential by
the municipality, (e) the legal recourse of the lease obligee in the event of
such a failure to appropriate funding and (f) any limitations which are imposed
on the lease obligor's ability to utilize substitute property or services than
those covered by the lease obligation. The Fund will invest in lease obligations
which contain non-appropriation clauses only if such obligations are rated
investment grade, at the time of investment.
 
  Also included in the term municipal securities are participation certificates
issued by state and local governments or authorities to finance the acquisition
of equipment and facilities. They may represent participations in a lease, an
installment purchase contract, or a conditional sales contract.
 
  The Fund may purchase floating and variable rate demand notes, which are
municipal securities normally having a stated maturity in excess of one year,
but which permit the holder to demand payment of principal at any time, or at
specified intervals. The issuer of such notes normally has a corresponding
right, after a given period, to prepay at its discretion upon notice to the
noteholders the outstanding principal amount of the notes plus accrued interest.
The interest rate on a floating rate demand note is based on a known lending
rate, such as a bank's prime rate, and is adjusted automatically each time such
rate is adjusted. The interest rate on a variable rate demand note is adjusted
automatically at specified intervals.
 
  The Fund also may invest up to 15% of its total assets in derivative variable
rate municipal securities such as inverse floaters whose rates vary inversely
with changes in market rates of interest. Such derivative variable rate
municipal securities may pay a rate of interest determined by applying a
multiple to the variable rate. The extent of increases and decreases in the
value of derivative municipal securities whose rates vary inversely with changes
in market rates of interest in response to such changes in market rates
generally will be larger than comparable changes in the value of an equal
principal amount of a fixed rate municipal security having similar credit
quality, redemption provisions and maturity. In addition, the Fund may invest in
derivative municipal securities the terms of which include elements of, or are
similar in effect to, certain Strategic Transactions in which the Fund may
engage.
 
  The Fund may also acquire custodial receipts or certificates underwritten by
securities dealers or banks that evidence ownership of future interest payments,
principal payments or both on certain municipal securities. The underwriter of
these certificates or receipts typically purchases municipal securities and
deposits the securities in an irrevocable trust or custodial account with a
custodian bank, which then issues receipts or certificates that evidence
ownership of the periodic unmatured coupon payments and the final principal
payment on the obligations. Although under the terms of a custodial receipt, the
Fund typically would be authorized to assert its rights directly against the
issuer of the underlying obligation, the Fund could be required to assert
through the custodian bank those rights as may exist against the underlying
issuer. Thus, in the event the underlying issuer fails to pay principal and/or
interest when due, the Fund may be subject to delays, expenses and risks that
are greater than those that would have been involved if the Fund had purchased a
direct obligation of the issuer. In addition, in the event that the trust or
custodial account in which the underlying security has been deposited is
determined to be an association taxable as a corporation, instead of a
non-taxable entity, the yield on the underlying security would be reduced in
recognition of any taxes paid.

  The "issuer" of municipal securities generally is deemed to be the
governmental agency, authority, instrumentality or other political subdivision,
or the non-governmental user of a revenue bond-financed facility, the assets and
revenues of which will be used to meet the payment obligations, or the guarantee
of such payment obligations, of the municipal securities.
 
  Although the Fund will invest at least 65% of its total assets in municipal
securities rated investment grade at the time of investment, municipal
securities, like other debt obligations, are subject to the risk of non-payment.
The ability of issuers of municipal securities to make timely payments of
interest and principal may be adversely impacted in general economic downturns
and as relative governmental cost burdens are allocated and reallocated among
federal, state and local governmental units. Such non-payment would result in a
reduction of income to the Fund, and could result in a reduction in the value of
the municipal security experiencing non-payment and a potential decrease in the
net asset value of the Fund. Issuers of municipal securities might seek
protection under the bankruptcy laws. In the event of bankruptcy of such an
issuer, the Fund could experience delays and limitations with respect to the
collection of principal and interest on such municipal securities and the Fund
may not, in all circumstances, be able to collect all principal and interest to
which it is entitled. To enforce its rights in the event of a default in the
payment of interest or repayment of principal, or both, the Fund may take
possession of and manage the assets securing the issuer's obligations on such
securities, which may increase the Fund's operating expenses and adversely
affect the net asset value of the Fund. Any income derived from the Fund's
ownership or operation of such assets may not be tax-exempt. In addition, the
Fund's intention to qualify as a "regulated investment company" under the
Internal Revenue Code of 1986, as amended (the "Code"), may limit the extent to
which the Fund may exercise its rights by taking possession of such assets,
because as a regulated investment company the Fund is subject to certain
limitations on its investments and on the nature of its income. Further, in
connection with the working out or restructuring of a defaulted security, the
Fund may acquire additional securities of the issuer, the acquisition of which
may be deemed to be a loan of money or property. Such additional securities
should be considered speculative with respect to the capacity to pay interest
and/or repay principal in accordance with their terms.
 
  The Fund may invest the remainder of its total assets in lower grade municipal
securities. The amount of available information about the financial condition of
municipal securities issuers is generally less extensive than that for corporate
issuers with publicly traded securities and the market for municipal securities
is considered to be generally less liquid than the market for corporate debt
obligations. Liquidity relates to the ability of a Fund to sell a security in a
timely manner at a price which reflects the value of that security. As discussed
below, the market for lower grade municipal securities is considered generally
to be less liquid than the market for investment grade municipal securities.
Further, municipal securities in which the Fund may invest include special
obligation bonds, lease obligations, participation certificates and variable
rate instruments. The market for such securities may be particularly less
liquid. The relative illiquidity of some of the Fund's portfolio securities may
adversely affect the ability of the Fund to dispose of such securities in a
timely manner and at a price which reflects the value of such security in the
Adviser's judgment. Although the issuer of some such municipal securities may be
obligated to redeem such securities at face value, such redemption could result
in capital losses to the Fund to the extent that such municipal securities were
purchased by the Fund at a premium to face value. The market for less liquid
securities tends to be more volatile than the market for more liquid securities
and market values of relatively illiquid securities may be more susceptible to
change as a result of adverse publicity and investor perceptions than are the
market values of higher grade, more liquid securities.
 
  The Fund's net asset value will change with changes in the value of its
portfolio securities. Because the Fund will invest primarily in fixed income
municipal securities, the Fund's net asset value can be expected to change as
general levels of interest rates fluctuate. When interest rates decline, the
value of a portfolio invested in fixed income securities can be expected to
rise. Conversely, when interest rates rise, the value of a portfolio invested in
fixed income securities can be expected to decline. Net asset value and market
value may be volatile due to the Fund's investment in lower grade and less
liquid municipal securities. Volatility may be greater during periods of general
economic uncertainty.
 
  The Adviser values the Fund's investments pursuant to guidelines adopted and
periodically reviewed by the Board of Trustees. To the extent that there is no
established retail market for some of the securities in which the Fund may
invest, there may be relatively inactive trading in such securities and the
ability of the Adviser
 
                                       B-6
<PAGE>   643
 
to accurately value such securities may be adversely affected. During periods of
reduced market liquidity and in the absence of readily available market
quotations for securities held in the Fund's portfolio, the responsibility of
the Adviser to value the Fund's securities becomes more difficult and the
Adviser's judgment may play a greater role in the valuation of the Fund's
securities due to the reduced availability of reliable objective data. To the
extent that the Fund invests in illiquid securities and securities which are
restricted as to resale, the Fund may incur additional risks and costs. Illiquid
and restricted securities are particularly difficult to dispose of.
 
  Lower grade municipal securities generally involve greater credit risk than
higher grade municipal securities. A general economic downturn or a significant
increase in interest rates could severely disrupt the market for lower grade
municipal securities and adversely affect the market value of such securities.
In addition, in such circumstances, the ability of issuers of lower grade
municipal securities to repay principal and to pay interest, to meet projected
financial goals and to obtain additional financing may be adversely affected.
Such consequences could lead to an increased incidence of default for such
securities and adversely affect the value of the lower grade municipal
securities in the Fund's portfolio and thus the Fund's net asset value. The
secondary market prices of lower grade municipal securities are less sensitive
to changes in interest rates than are those for higher rated municipal
securities, but are more sensitive to adverse economic changes or individual
issuer developments. Adverse publicity and investor perceptions, whether or not
based on rational analysis, may also affect the value and liquidity of lower
grade municipal securities.
 
  Yields on the Fund's portfolio securities can be expected to fluctuate over
time. In addition, periods of economic uncertainty and changes in interest rates
can be expected to result in increased volatility of the market prices of the
lower grade municipal securities in the Fund's portfolio and thus in the net
asset value of the Fund. Net asset value and market value may be volatile due to
the Fund's investment in lower grade and less liquid municipal securities.
Volatility may be greater during periods of general economic uncertainty. The
Fund may incur additional expenses to the extent it is required to seek recovery
upon a default in the payment of interest or a repayment of principal on its
portfolio holdings, and the Fund may be unable to obtain full recovery thereof.
In the event that an issuer of securities held by the Fund experiences
difficulties in the timely payment of principal or interest and such issuer
seeks to restructure the terms of its borrowings, the Fund may incur additional
expenses and may determine to invest additional capital with respect to such
issuer or the project or projects to which the Fund's portfolio securities
relate. Recent and proposed legislation may have an adverse impact on the market
for lower grade municipal securities. Recent legislation requires federally-
insured savings and loan associations to divest their investments in lower grade
bonds. Other legislation has been proposed which, if enacted, could have an
adverse impact on the market for lower grade municipal securities.
 
  The Fund will rely on the Adviser's judgment, analysis and experience in
evaluating the creditworthiness of an issue. In this evaluation, the Adviser
will take into consideration, among other things, the issuer's financial
resources, its sensitivity to economic conditions and trends, its operating
history, the quality of the issuer's management and regulatory matters. The
Adviser also may consider, although it does not rely primarily on, the credit
ratings of S&P, Moody's or another NRSRO in evaluating municipal securities.
Such ratings evaluate only the safety of principal and interest payments, not
market value risk. Additionally, because the creditworthiness of an issuer may
change more rapidly than is able to be timely reflected in changes in credit
ratings, the Adviser continuously monitors the issuers of municipal securities
held in the Fund's portfolio.
 
  Because issuers of lower grade municipal securities frequently choose not to
seek a rating of their municipal securities, the Adviser will be required to
determine the relative investment quality of many of the municipal securities in
the Fund's portfolio. Further, because the Fund may invest in lower grade
municipal securities, achievement by the Fund of its investment objective may be
more dependent upon the Adviser's investment analysis than would be the case if
the Fund were investing exclusively in higher grade municipal securities. The
relative lack of financial information available with respect to issuers of
municipal securities may adversely affect the Adviser's ability to successfully
conduct the required investment analysis.
 
  The Fund may invest up to 15% of its total assets in illiquid securities,
securities the disposition of which is subject to substantial legal or
contractual restrictions on resale and securities that are not readily
marketable.
 
                                       B-7
<PAGE>   644
 
The sale of restricted and illiquid securities often requires more time and
results in higher brokerage charges or dealer discounts and other selling
expenses than does the sale of securities eligible for trading on national
securities exchanges or in the over-the-counter markets. Restricted securities
may sell at a price lower than similar securities that are not subject to
restrictions on resale. Restricted securities salable among qualified
institutional buyers without restriction pursuant to Rule 144A under the
Securities Act of 1933, as amended, that are determined to be liquid by the
Adviser under guidelines adopted by the Board of Trustees of the Trust (under
which guidelines the Adviser will consider factors such as trading activities
and the availability of price quotations), will not be treated as restricted
securities by the Fund pursuant to such rules. The Fund may, from time to time,
adopt a more restrictive limitation with respect to investment in illiquid and
restricted securities in order to comply with the most restrictive state
securities law, currently 10%. This policy does not include restricted
securities eligible for resale pursuant to Rule 144A under the Securities Act of
1933, as amended, which the Board of Trustees or the Fund's investment adviser
has determined under Board-approved guidelines to be liquid. The Fund's policy
with respect to investment in illiquid and restricted securities is not a
fundamental policy and may be changed by the Board of Trustees, in consultation
with the adviser, without obtaining shareholder approval.
 
STRATEGIC TRANSACTIONS
 
  The Fund may, but is not required to, utilize various other investment
strategies as described below to hedge various market risks (such as interest
rates and broad or specific market movements) or to manage the effective
maturity or duration of the Fund's fixed-income securities. Such strategies are
generally accepted by modern portfolio managers and are regularly utilized by
many mutual funds and other institutional investors. Techniques and instruments
may change over time as new instruments and strategies are developed or
regulatory changes occur.
 
  In the course of pursuing these investment strategies, the Fund may purchase
and sell derivative instruments such as exchange-listed and over-the-counter put
and call options on securities, fixed-income indices and other financial
instruments, purchase and sell financial futures contracts and options thereon,
enter into various interest rate transactions such as swaps, caps, floors or
collars (collectively, all the above are called "Strategic Transactions").
Strategic Transactions may be used to attempt to protect against possible
changes in the market value of securities held in or to be purchased for the
Fund's portfolio resulting from securities markets fluctuations, to protect the
Fund's unrealized gains in the value of its portfolio securities, to facilitate
the sale of such securities for investment purposes, to manage the effective
maturity or duration of the Fund's portfolio, or to establish a position in the
derivatives markets as a temporary substitute for purchasing or selling
particular securities.
 
  Any or all of these investment techniques may be used at any time and there is
no particular strategy that dictates the use of one technique rather than
another, as use of any Strategic Transaction is a function of numerous variables
including market conditions. The ability of the Fund to utilize these Strategic
Transactions successfully will depend on the Adviser's ability to predict
pertinent market movements, which cannot be assured. The Fund will comply with
applicable regulatory requirements when implementing these strategies,
techniques and instruments. Strategic Transactions involving financial futures
and options thereon will be purchased, sold or entered into only for bona fide
hedging, risk management or portfolio management purposes and not for
speculative purposes.
 
  Strategic Transactions have risks associated with them including possible
default by the other party to the transaction, illiquidity and, to the extent
the Adviser's view as to certain market movements is incorrect, the risk that
the use of such Strategic Transactions could result in losses greater than if
they had not been used. Use of put and call options may result in losses to the
Fund, force the sale or purchase of portfolio securities at inopportune times or
for prices other than current market values, limit the amount of appreciation
the Fund can realize on its investments or cause the Fund to hold a security it
might otherwise sell. The use of options and futures transactions entails
certain other risks. In particular, the variable degree of correlation between
price movements of futures contracts and price movements in the related
portfolio position of the Fund creates the possibility that losses on the
hedging instrument may be greater than gains in the value of the Fund's
position. In addition, futures and options markets may not be liquid in all
circumstances and certain
 
                                       B-8
<PAGE>   645
 
over-the-counter options may have no markets. As a result, in certain markets,
the Fund might not be able to close out a transaction without incurring
substantial losses, if at all. Although the use of futures and options
transactions for hedging should tend to minimize the risk of loss due to a
decline in the value of the hedged position, at the same time they tend to limit
any potential gain which might result from an increase in value of such
position. Finally, the daily variation margin requirements for futures contracts
would create a greater ongoing potential financial risk than would purchases of
options, where the exposure is limited to the cost of the initial premium.
Losses resulting from the use of Strategic Transactions would reduce net asset
value, and possibly income, and such losses can be greater than if the Strategic
Transactions had not been utilized. Income earned or deemed to be earned, if
any, by the Fund from its Strategic Transactions will generally be taxable
income of the Fund. See "Tax Status" in the Prospectus.
 
  GENERAL CHARACTERISTICS OF OPTIONS.   Put options and call options typically
have similar structural characteristics and operational mechanics regardless of
the underlying instrument on which they are purchased or sold. Thus, the
following general discussion relates to each of the particular types of options
discussed in greater detail below. In addition, many Strategic Transactions
involving options require segregation of Fund assets in special accounts, as
described below under "Use of Segregated and Other Special Accounts."
 
  A put option gives the purchaser of the option, upon payment of a premium, the
right to sell, and the writer the obligation to buy, the underlying security,
commodity, index, or other instrument at the exercise price. For instance, the
Fund's purchase of a put option on a security might be designed to protect its
holdings in the underlying instrument (or, in some cases, a similar instrument)
against a substantial decline in the market value by giving the Fund the right
to sell such instrument at the option exercise price. A call option, upon
payment of a premium, gives the purchaser of the option the right to buy, and
the seller the obligation to sell, the underlying instrument at the exercise
price. The Fund's purchase of a call option on a security, financial future,
index, or other instrument might be intended to protect the Fund against an
increase in the price of the underlying instrument that it intends to purchase
in the future by fixing the price at which it may purchase such instrument. An
American style put or call option may be exercised at any time during the option
period while a European style put or call option may be exercised only upon
expiration or during a fixed period prior thereto. The Fund is authorized to
purchase and sell exchange listed options and over-the-counter options ("OTC
options"). Exchange listed options are issued by a regulated intermediary such
as the Options Clearing Corporation ("OCC"), which guarantees the performance of
the obligations of the parties to such options. The discussion below uses the
OCC as a paradigm, but is also applicable to other financial intermediaries.
 
  With certain exceptions, OCC issued and exchange listed options generally
settle by physical delivery of the underlying security or currency, although in
the future cash settlement may become available. Index options and Eurodollar
instruments are cash settled for the net amount, if any, by which the option is
"in-the-money" (i.e., where the value of the underlying instrument exceeds, in
the case of a call option, or is less than, in the case of a put option, the
exercise price of the option) at the time the option is exercised. Frequently,
rather than taking or making delivery of the underlying instrument through the
process of exercising the option, listed options are closed by entering into
offsetting purchase or sale transactions that do not result in ownership of the
new option.
 
  The Fund's ability to close out its position as a purchaser or seller of an
OCC or exchange listed put or call option is dependent, in part, upon the
liquidity of the option market. Among the possible reasons for the absence of a
liquid option 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 including
reaching daily price limits; (iv) interruption of the normal operations of the
OCC or an exchange; (v) inadequacy of the facilities of an exchange or 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 relevant market for that option on that exchange would cease
to exist, although outstanding options on that exchange would generally continue
to be exercisable in accordance with their terms.
 
                                       B-9
<PAGE>   646
 
  The hours of trading for listed options may not coincide with the hours during
which the underlying financial instruments are traded. To the extent that the
option markets close before the markets for the underlying financial
instruments, significant price and rate movements can take place in the
underlying markets that cannot be reflected in the option markets.
 
  OTC options are purchased from or sold to securities dealers, financial
institutions or other parties ("Counterparties") through direct bilateral
agreement with the Counterparty. In contrast to exchange listed options, which
generally have standardized terms and performance mechanics, all the terms of an
OTC option, including such terms as method of settlement, term, exercise price,
premium, guarantees and security, are set by negotiation of the parties. The
Fund will only sell OTC options that are subject to a buy-back provision
permitting the Fund to require the Counterparty to sell the option back to the
Fund at a formula price within seven days. The Fund expects generally to enter
into OTC options that have cash settlement provisions, although it is not
required to do so.
 
  Unless the parties provide for it, there is no central clearing or guaranty
function in an OTC option. As a result, if the Counterparty fails to make or
take delivery of the security, or other instrument underlying an OTC option it
has entered into with the Fund or fails to make a cash settlement payment due in
accordance with the terms of that option, the Fund will lose any premium it paid
for the option as well as any anticipated benefit of the transaction.
Accordingly, the Adviser must assess the creditworthiness of each such
Counterparty or any guarantor or credit enhancement of the Counterparty's credit
to determine the likelihood that the terms of the OTC option will be satisfied.
The Fund will engage in OTC option transactions only with United States
government securities dealers recognized by the Federal Reserve Bank of New York
as "primary dealers", or broker dealers, domestic or foreign banks or other
financial institutions which have received (or the guarantors of the obligation
of which have received) a short-term credit rating of "A-1" from Standard &
Poors Ratings Group ("S&P") or "P-1" from Moody's Investors Service, Inc.
("Moody's") or an equivalent rating from any other nationally recognized
statistical rating organization ("NRSRO"). The staff of the SEC currently takes
the position that, in general, OTC options on securities other than U.S.
Government securities purchased by the Fund, and portfolio securities "covering"
the amount of the Fund's obligation pursuant to an OTC option sold by it (the
cost of the sell-back plus the in-the-money amount, if any) are illiquid, and
are subject to the Fund's limitation on investing no more than 15% of its assets
in illiquid securities.
 
  If the Fund sells a call option, the premium that it receives may serve as a
partial hedge, to the extent of the option premium, against a decrease in the
value of the underlying securities or instruments in its portfolio or will
increase the Fund's income. The sale of put options can also provide income.
 
  The Fund may purchase and sell call options on securities, including U.S.
Treasury and agency securities, municipal obligations, mortgage-backed
securities and Eurodollar instruments that are traded on U.S. and foreign
securities exchanges and in the over-the-counter markets. All calls sold by the
Fund must be "covered" (i.e., the Fund must own the securities or futures
contract subject to the call) or must meet the asset segregation requirements
described below as long as the call is outstanding. Even though the Fund will
receive the option premium to help protect it against loss, a call sold by the
Fund exposes the Fund during the term of the option to possible loss of
opportunity to realize appreciation in the market price of the underlying
security or instrument and may require the Fund to hold a security or instrument
which it might otherwise have sold. In the event of exercise of a call option
sold by the Fund with respect to securities not owned by the Fund, the Fund may
be required to acquire the underlying security at a disadvantageous price in
order to satisfy its obligation with respect to the call option.
 
  The Fund may purchase and sell put options on securities including U.S.
Treasury and agency securities, mortgage-backed securities, municipal
obligations and Eurodollar instruments (whether or not it holds the above
securities in its portfolio.) The Fund will not sell put options if, as a
result, more than 50% of the Fund's assets would be required to be segregated to
cover its potential obligations under such put options other than those with
respect to futures and options thereon. In selling put options, there is a risk
that the Fund may be required to buy the underlying security at a
disadvantageous price above the market price.
 
  GENERAL CHARACTERISTICS OF FUTURES.  The Fund may enter into financial futures
contracts or purchase or sell put and call options on such futures as a hedge
against anticipated interest rate or fixed-income market
 
                                      B-10
<PAGE>   647
 
changes, for duration management and for risk management purposes. Futures are
generally bought and sold on the commodities exchanges where they are listed
with payment of initial and variation margin as described below. The purchase of
a futures contract creates a firm obligation by the Fund, as purchaser, to take
delivery from the seller the specific type of financial instrument called for in
the contract at a specific future time for a specified price (or, with respect
to index futures and Eurodollar instruments, the net cash amount). The sale of a
futures contract creates a firm obligation by the Fund, as seller, to deliver to
the buyer the specific type of financial instrument called for in the contract
at a specific future time for a specified price (or, with respect to index
futures and Eurodollar instruments, the net cash amount). Options on futures
contracts are similar to options on securities except that 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 and obligates the seller to deliver such
option.
 
  The Fund's use of financial futures and options thereon will in all cases be
consistent with applicable regulatory requirements and in particular the rules
and regulations of the Commodity Futures Trading Commission and will be entered
into only for bona fide hedging, risk management (including duration management)
or other portfolio management purposes. Typically, maintaining a futures
contract or selling an option thereon requires the Fund to deposit with a
financial intermediary as security for its obligations an amount of cash or
other specified assets (initial margin) which initially is typically 1% to 10%
of the face amount of the contract (but may be higher in some circumstances).
Additional cash or assets (variation margin) may be required to be deposited
thereafter on a daily basis as the mark to market value of the contract
fluctuates. The purchase of options on financial futures involves payment of a
premium for the option without any further obligation on the part of the Fund.
If the Fund exercises an option on a futures contract it will be obligated to
post initial margin (and potential subsequent variation margin) for the
resulting futures position just as it would for any position. Futures contracts
and options thereon are generally settled by entering into an offsetting
transaction but there can be no assurance that the position can be offset prior
to settlement at an advantageous price nor that delivery will occur.
 
  The Fund will not enter into a futures contract or related option (except for
closing transactions) for other than bona fide hedging purposes if, immediately
thereafter, the sum of the amount of its initial margin and premiums on open
futures contracts and options thereon would exceed 5% of the Fund's net assets
(taken at current value); however, in the case of an option that is in-the-money
at the time of the purchase, the in-the-money amount may be excluded in
calculating the 5% limitation. Certain state securities laws to which the Fund
may be subject may further restrict the Fund's ability to engage in transactions
in futures contracts and related options. The segregation requirements with
respect to futures contracts and options thereon are described below.
 
  OPTIONS ON SECURITIES INDICES AND OTHER FINANCIAL INDICES.  The Fund also may
purchase and sell call and put options on securities indices and other financial
indices and in so doing can achieve many of the same objectives it would achieve
through the sale or purchase of options on individual securities or other
instruments. Options on securities indices and other financial indices are
similar to options on a security or other instrument except that, rather than
settling by physical delivery of the underlying instrument, they settle by cash
settlement, i.e., an option on an index gives the holder the right to receive,
upon exercise of the option, an amount of cash if the closing level of the index
upon which the option is based exceeds, in the case of a call, or is less than,
in the case of a put, the exercise price of the option (except if, in the case
of an OTC option, physical delivery is specified). This amount of cash is equal
to the excess of the closing price of the index over the exercise price of the
option, which also may be multiplied by a formula value. The seller of the
option is obligated, in return for the premium received, to make delivery of
this amount. The gain or loss on an option on an index depends on price
movements in the instruments making up the market, market segment, industry or
other composite on which the underlying index is based, rather than price
movements in individual securities, as is the case with respect to options on
securities.
 
  COMBINED TRANSACTIONS.  The Fund may enter into multiple transactions,
including multiple options transactions, multiple futures transactions and
multiple interest rate transactions and any combination of futures, options and
interest rate transactions ("component" transactions), instead of a single
Strategic Transaction, as part of a single or combined strategy when, in the
opinion of the Adviser, it is in the best interests of the Fund to do so. A
combined transaction will usually contain elements of risk that are present in
each of its component transactions. Although combined transactions are normally
entered into based on the
 
                                      B-11
<PAGE>   648
 
Adviser's judgment that the combined strategies will reduce risk or otherwise
more effectively achieve the desired portfolio management goal, it is possible
that the combination will instead increase such risks or hinder achievement of
the portfolio management objective.
 
  SWAPS, CAPS, FLOORS AND COLLARS.  Among the Strategic Transactions into which
the Fund may enter are interest rate and index swaps and the purchase or sale of
related caps, floors and collars. The Fund expects to enter into these
transactions primarily to preserve a return or spread on a particular investment
or portion of its portfolio, as a duration management technique or to protect
against any increase in the price of securities the Fund anticipates purchasing
at a later date. The Fund intends to use these transactions as hedges and not as
speculative investments and will not sell interest rate caps or floors where it
does not own securities or other instruments providing the income stream the
Fund may be obligated to pay. Interest rate swaps involve the exchange by the
Fund with another party of their respective commitments to pay or receive
interest, e.g., an exchange of floating rate payments for fixed rate payments
with respect to a notional amount of principal. An index swap is an agreement to
swap cash flows on a notional amount based on changes in the values of the
reference indices. The purchase of a cap entitles the purchaser to receive
payments on a notional principal amount from the party selling such cap to the
extent that a specified index exceeds a predetermined interest rate or amount.
The purchase of a floor entitles the purchaser to receive payments on a notional
principal amount from the party selling such floor to the extent that a
specified index falls below a predetermined interest rate or amount. A collar is
a combination of a cap and a floor that preserves a certain return within a
predetermined range of interest rates or values.
 
  The Fund will usually enter into swaps on a net basis, i.e., the two payment
streams are netted out in a cash settlement on the payment date or dates
specified in the instrument, with the Fund receiving or paying, as the case may
be, only the net amount of the two payments. Inasmuch as these swaps, caps,
floors and collars are entered into for good faith hedging purposes, the Adviser
and the Fund believe such obligations do not constitute senior securities under
the 1940 Act and, accordingly, will not treat them as being subject to its
borrowing restrictions. The Fund will not enter into any swap, cap, floor or
collar transaction unless, at the time of entering into such transaction, the
unsecured long-term debt of the Counterparty, combined with any credit
enhancements, is rated at least "A" by S&P or Moody's or has an equivalent
equity rating from an NRSRO or is determined to be of equivalent credit quality
by the Adviser. If there is a default by the Counterparty, the Fund may have
contractual remedies pursuant to the agreements related to the transaction. The
swap market has grown substantially in recent years with a large number of banks
and investment banking firms acting both as principals and agents utilizing
standardized swap documentation. As a result, the swap market has become
relatively liquid. Caps, floors and collars are more recent innovations for
which standardized documentation has not yet been fully developed and,
accordingly, they are less liquid than swaps.
 
   
  USE OF SEGREGATED AND OTHER SPECIAL ACCOUNTS.  Many Strategic Transactions, in
addition to other requirements, require that the Fund segregate liquid
high-grade assets with its custodian to the extent Fund obligations are not
otherwise "covered" through ownership of the underlying security, financial
instrument or currency. In general, either the full amount of any obligation by
the Fund to pay or deliver securities or assets must be covered at all times by
the securities, instruments or currency required to be delivered, or, subject to
any regulatory restrictions, an amount of cash or liquid securities at least
equal to the current amount of the obligation must be segregated with the
custodian. The segregated assets cannot be sold or transferred unless equivalent
assets are substituted in their place or it is no longer necessary to segregate
them. For example, a call option written by the Fund will require the Fund to
hold the securities subject to the call (or securities convertible into the
needed securities without additional consideration) or to segregate liquid
securities sufficient to purchase and deliver the securities if the call is
exercised. A call option sold by the Fund on an index will require the Fund to
own portfolio securities which correlate with the index or to segregate liquid
securities equal to the excess of the index value over the exercise price on a
current basis. A put option written by the Fund requires the Fund to segregate
liquid securities equal to the exercise price.
    
 
  OTC options entered into by the Fund, including those on securities, financial
instruments or indices and OCC issued and exchange listed index options, will
generally provide for cash settlement. As a result, when the Fund sells these
instruments it will only segregate an amount of assets equal to its accrued net
obligations, as there is no requirement for payment or delivery of amounts in
excess of the net amount. These amounts will
 
                                      B-12
<PAGE>   649
 
equal 100% of the exercise price in the case of a non cash-settled put, the same
as an OCC guaranteed listed option sold by the Fund, or the in-the-money amount
plus any sell-back formula amount in the case of a cash-settled put or call. In
addition, when the Fund sells a call option on an index at a time when the
in-the-money amount exceeds the exercise price, the Fund will segregate, until
the option expires or is closed out, cash or cash equivalents equal in value to
such excess. OCC issued and exchange listed options sold by the Fund other than
those above generally settle with physical delivery, and the Fund will segregate
an amount of assets equal to the full value of the option. OTC options settling
with physical delivery, or with an election of either physical delivery or cash
settlement, will be treated the same as other options settling with physical
delivery.
 
  In the case of a futures contract or an option thereon, the Fund must deposit
initial margin and possible daily variation margin in addition to segregating
assets sufficient to meet its obligation to purchase or provide securities or
currencies, or to pay the amount owed at the expiration of an index- based
futures contract. Such assets may consist of cash, cash equivalents, liquid debt
or equity securities or other acceptable assets.
 
   
  With respect to swaps, the Fund will accrue the net amount of the excess, if
any, of its obligations over its entitlements with respect to each swap on a
daily basis and will segregate an amount of cash or liquid securities having a
value equal to the accrued excess. Caps, floors and collars require segregation
of assets with a value equal to the Fund's net obligation, if any.
    
 
  Strategic Transactions may be covered by other means when consistent with
applicable regulatory policies. The Fund may also enter into offsetting
transactions so that its combined position, coupled with any segregated assets,
equals its net outstanding obligation in related options and Strategic
Transactions. For example, the Fund could purchase a put option if the strike
price of that option is the same or higher than the strike price of a put option
sold by the Fund. Moreover, instead of segregating assets if the Fund held a
futures or forward contract, it could purchase a put option on the same futures
or forward contract with a strike price as high or higher than the price of the
contract held. Other Strategic Transactions may also be offset in combinations.
If the offsetting transaction terminates at the time of or after the primary
transaction no segregation is required, but if it terminates prior to such time,
assets equal to any remaining obligation would need to be segregated.
 
  The Fund's activities involving Strategic Transactions may be limited by the
requirements of the Code for qualification as a regulated investment company.

                  DESCRIPTION OF MUNICIPAL SECURITIES RATINGS
 
  STANDARD & POOR'S RATINGS GROUP--A brief description of the applicable
Standard & Poor's Ratings Group ("S&P") rating symbols and their meanings (as
published by S&P) follows:
 
     1. Debt
 
   
          A S&P corporate or municipal debt rating is a current assessment of
     the creditworthiness of an obligor with respect to a specific obligation.
     This assessment may take into consideration obligors such as guarantors,
     insurers, or lessees.
    
 
          The debt rating is not a recommendation to purchase, sell, or hold a
     security, inasmuch as it does not comment as to market price or suitability
     for a particular investor.
 
          The ratings are based on current information furnished by the issuer
     or obtained by S&P from other sources it considers reliable. S&P does not
     perform any 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 based on other circumstances.
 
        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;
 
                                      B-13
<PAGE>   650
 
        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.
 
<TABLE>
    <S>         <C>
    AAA         Debt rated 'AAA' has the highest rating assigned by S&P.
                Capacity to pay interest and repay principal is extremely
                strong.
 
    AA          Debt rated 'AA' has a very strong capacity to pay interest
                and repay principal and differs from the highest rated
                issues only in small degree.
 
    A           Debt rated 'A' has a strong capacity to pay interest and
                repay principal although it is somewhat more susceptible to
                the adverse effects of changes in circumstances and economic
                conditions than debt in higher-rated categories.
 
    BBB         Debt rated 'BBB' is regarded as having an adequate capacity
                to pay interest and repay principal. Whereas it normally
                exhibits adequate protection parameters, adverse economic
                conditions or changing circumstances are more likely to lead
                to a weakened capacity to pay interest and repay principal
                for debt in this category than in higher-rated categories.
 
    BB          Debt rated 'BB', 'B', 'CCC', 'CC' and 'C' is regarded, on
    B           balance, as predominantly speculative with respect to
    CCC         capacity to pay interest and repay principal. 'BB' indicates
    CC          the least degree of speculation and 'C' the highest. While
    C           such debt will likely have some quality and protective
                characteristics, these are outweighed by large uncertainties
                or large exposures to adverse conditions.
 
    BB          Debt rated 'BB' has less near-term vulnerability to default
                than other speculative issues. However, it faces major
                ongoing uncertainties of exposure to adverse business,
                financial, or economic conditions which could lead to
                inadequate capacity to meet timely interest and principal
                payments. The 'BB' rating category is also used for debt
                subordinated to senior debt that is assigned an actual or
                implied 'BBB-' rating.
 
    B           Debt rated 'B' has a greater vulnerability to default but
                currently has the capacity to meet interest payments and
                principal repayments. Adverse business, financial, or
                economic conditions will likely impair capacity or
                willingness to pay interest and repay principal. The 'B'
                rating category is also used for debt subordinated to senior
                debt that is assigned an actual or implied 'BB' or 'BB-'
                rating.
 
    CCC         Debt rated 'CCC' has a currently identifiable vulnerability
                to default, and is dependent upon favorable business,
                financial, and economic conditions to meet timely payment of
                interest and repayment of principal. In the event of adverse
                business, financial, or economic conditions, it is not
                likely to have the capacity to pay interest and repay
                principal. The 'CCC' rating category is also used for debt
                subordinated to senior debt that is assigned an actual or
                implied 'B' or 'B-' rating.
 
    CC          The rating 'CC' typically is applied to debt subordinated to
                senior debt that is assigned an actual or implied 'CCC'
                rating.
 
    C           The rating 'C' typically is applied to debt subordinated to
                senior debt which is assigned an actual or implied 'CCC-'
                debt rating. The 'C' rating may be used to cover a situation
                where a bankruptcy petition has been filed, but debt service
                payments are continued.
 
    CI          The rating 'CI' is reserved for income bonds on which no
                interest is being paid.
 
    D           Debt rated 'D' is in payment default. The 'D' rating
                category is used when interest payments or principal
                payments are not made on the date due even if the applicable
                grace period has not expired, unless S&P believes that such
                payments will be made during such grace period. The 'D'
                rating also will be used upon the filing of a bankruptcy
                petition if debt service payments are jeopardized.

<PAGE>   651
                PLUS (+) or MINUS (-): The ratings from 'AA' to 'CCC' may be
                modified by the addition of a plus or minus sign to show
                relative standing within the major rating categories.
 
    C           The letter 'c' indicates that the holders option to tender
                the security for purchase may be canceled under certain
                prestated conditions enumerated in the tender option
                documents.
 
    I           The letter 'i' indicates the rating is implied. Such ratings
                are assigned only on request to entities that do not have
                specific debt issues to be rated. In addition, implied
                ratings are assigned to governments that have not requested
                explicit ratings for specific debt issues. Implied ratings
                on governments represent the sovereign ceiling or upper
                limit for ratings on specific debt issues of entities
                domiciled in the country.
 
    L           The letter 'L' indicates that the rating pertains to the
                principal amount of those bonds to the extent that the
                underlying deposit collateral is federally insured and
                interest is adequately collateralized. In the case of
                certificates of deposit, the letter 'L' indicates that the
                deposit, combined with other deposits being held in the same
                right and capacity, will be honored for principal and
                accrued pre-default interest up to the federal insurance
                limits within 30 days after closing of the insured
                institution or, in the event that the deposit is assumed by
                a successor insured institution, upon maturity.
 
    P           The letter 'p' indicates that the rating is provisional. A
                provisional rating assumes the successful completion of the
                project being financed by the debt being rated and indicates
                that payment of debt service requirements is largely or
                entirely dependent upon the successful and timely completion
                of the project. This rating, however, while addressing
                credit quality subsequent to completion of the project,
                makes no comment on the likelihood of, or the risk of
                default upon failure of, such completion. The investor
                should exercise his own judgment with respect to such
                likelihood and risk.
 
                * Continuance of the rating is contingent upon S&P's receipt
                of an executed copy of the escrow agreement or closing
                  documentation confirming investments and cash flows.
 
    NR          Indicates that no public rating has been requested, that
                there is insufficient information on which to base a rating,
                or that S&P does not rate a particular type of obligation as
                a matter of policy.
 
                DEBT OBLIGATIONS OF ISSUERS OUTSIDE THE UNITED STATES AND
                ITS TERRITORIES are rated on the same basis as domestic
                corporate and municipal issues. The ratings measure the
                creditworthiness of the obliger but do not take into account
                currency exchange and related uncertainties.
 
      BOND INVESTMENT QUALITY STANDARDS: Under present commercial bank
    regulations issued by the Comptroller of the Currency, bonds rated in
    the top four categories ("AAA," "AA," "A," and "BBB," commonly known as
    "investment grade" ratings) are generally regarded as eligible for bank
    investment. In addition, the laws of various states governing legal
    investments impose certain rating or other standards for obligations
    eligible for investment by savings banks, trust companies, insurance
    companies, and fiduciaries generally.

     2. MUNICIPAL NOTES
 
       A S&P note rating reflects the liquidity factors and market-access risks
     unique to notes. Notes maturing in 3 years or less will likely receive a
     note rating. Notes maturing beyond 3 years will most likely receive a
     long-term debt rating.
 
       The following criteria will be used in making that assessment.
 
<TABLE>
    <S>         <C>
                -- Amortization schedule (the larger the final maturity
                relative to other maturities, the more likely the issue is
                   to be treated as a note).
 
                -- Source of payment (the more the issue depends on the
                market for its refinancing, the more likely it is to be
                   treated as a note).
 
                Note rating symbols are as follows:
 
    SP-1        Strong capacity to pay principal and interest. Issues
                determined to possess very strong characteristics are a plus
                (+) designation.
 
    SP-2        Satisfactory capacity to pay principal and interest, with
                some vulnerability to adverse financial and economic changes
                over the term of the notes.
 
    SP-3        Speculative capacity to pay principal and interest.
</TABLE>
 
     3. COMMERCIAL PAPER
 
       A S&P 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.
 
       Ratings are graded into several categories, ranging from 'A-1' for the
     highest quality obligations to 'D' for the lowest. These categories are as
     follows:
 
<TABLE>
    <S>         <C>
    A-1         This highest category indicates that the degree of safety
                regarding timely payment is strong. Those issues determined
                to possess extremely strong safety characteristics are
                denoted with a plus (+) sign designation.
 
    A-2         Capacity for timely payment on issues with this designation
                is satisfactory. However, the relative degree of safety is
                not as high as for issues designated 'A-1.'
 
    A-3         Issues carrying this designation have adequate capacity for
                timely payment. They are, however, more vulnerable to the
                adverse effects of changes in circumstances than obligations
                carrying the higher designations.
 
    B           Issues rated 'B' are regarded as having only speculative
                capacity for timely payment.
 
    C           This rating is assigned to short-term debt obligations with
                a doubtful capacity for payment.
 
    D           Debt rated 'D' is in payment default. The 'D' rating
                category is used when interest payments or principal
                payments are not made on the date due, even if the
                applicable grace period has not expired, unless S&P believes
                that such payments will be made during such grace period.
</TABLE>
 
  A commercial paper rating is not a recommendation to purchase or sell a
security. The ratings are based on current information furnished to S&P 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 or based on other information.
 
VARIABLE RATE DEMAND BONDS
 
  S&P assigns "dual" ratings to all long-term debt issues that have as part of
their provisions a variable rate demand or double feature.
 
  The first rating addresses the likelihood of repayment of principal and
interest as due, and the second rating addresses only the demand feature. The
long-term debt rating symbols are used for bonds to denote the
 
                                      B-16
<PAGE>   653
 
long-term maturity and the commercial paper rating symbols are used to denote
the put option (for example, 'AAA/A-1') or if the nominal maturity is short, a
rating of 'SP-1+/AAA' is assigned.
 
  MOODY'S INVESTORS SERVICE--A brief description of the applicable Moody's
Investors Service ("Moody's") rating symbols and their meanings (as published by
Moody's) follows:
 
     1. LONG-TERM MUNICIPAL BONDS
 
<TABLE>
    <S>         <C>
    AAA         Bonds which are rated Aaa are judged to be of the best
                quality. They carry the smallest degree of investment risk
                and are generally referred to as "gilt edge." Interest
                payments are protected by a large or by an exceptionally
                stable margin and principal is secure. While the various
                protective elements are likely to change, such changes as
                can be visualized are most unlikely to impair the
                fundamentally strong position of such issues.
 
    AA          Bonds which are rated Aa are judged to be of high quality by
                all standards. Together with the Aaa group they comprise
                what are generally known as high grade bonds. They are rated
                lower than the best bonds because margins of protection may
                not be as large as in Aaa securities or fluctuation of
                protective elements may be of greater amplitude or there may
                be other elements present which make the long-term risks
                appear somewhat larger than in Aaa securities.
 
    A           Bonds which are rated A possess many favorable investment
                attributes and are to be considered as upper medium grade
                obligations. Factors giving security to principal and
                interest are considered adequate but elements may be present
                which suggest a susceptibility to impairment sometime in the
                future.
 
    BAA         Bonds which are rated Baa are considered as medium-grade
                obligations (i.e., they are neither highly protected nor
                poorly secured). Interest payments and principal security
                appear adequate for the present but certain protective
                elements may be lacking or may be characteristically
                unreliable over any great length of time. Such bonds lack
                outstanding investment characteristics and in fact have
                speculative characteristics as well.
 
    BA          Bonds which are rated Ba are judged to have speculative
                elements; their future cannot be considered as well assured.
                Often the protection of interest and principal payments may
                be very moderate and thereby not well safeguarded during
                both good and bad times over the future. Uncertainty of
                position characterizes bonds in this class.
 
    B           Bonds which are rated B generally lack characteristics of
                the desirable investment. Assurance of interest and
                principal payments or of maintenance of other terms of the
                contract over any long period of time may be small.
 
    CAA         Bonds which are rated Caa are of poor standing. Such issues
                may be in default or there may be present elements of danger
                with respect to principal or interest.
 
    CA          Bonds which are rated Ca represent obligations which are
                speculative in a high degree. Such issues are often in
                default or have other marked shortcomings.
 
    C           Bonds which are rated C are the lowest rated class of bonds
                and issues so rated can be regarded as having extremely poor
                prospects of ever attaining any real investment standing.
 
    CON (..)    Bonds for which the security depends upon the completion of
                some act or the fulfillment of some condition are rated
                conditionally and designated with the prefix "Con" followed
                by the rating in parentheses. These are bonds secured by:
                (a) earnings of projects under construction, (b) earnings of
                projects unseasoned in operating experience, (c) rentals
                which begin when facilities are completed, or (d) payments
                to which some other limiting condition attaches the
                parenthetical rating denotes probable credit stature upon

    (P) (..)    When applied to forward delivery bonds, indicates that the
                rating is provisional pending the delivery of the bonds. The
                rating may be revised prior to delivery if changes occur in
                the legal documents or the underlying credit quality of the
                bonds.
 
    NOTE:       Moody's applies numerical modifiers, 1, 2 and 3 in each
                generic rating classification from AA to B. The modifier 1
                indicates that the company ranks in the higher end of its
                generic rating category; the modifier 2 indicates a
                mid-range ranking; and the modifier 3 indicates that the
                company ranks in the lower end of its generic rating
                category.
 
    
 
     2. SHORT-TERM EXEMPT NOTES
 
       Moody's ratings for state and municipal short-term obligations will be
     designated Moody's Investment Grade or (MIG). Such ratings recognize the
     differences between short-term credit risk and long-term risk. Factors
     affecting the liquidity of the borrower and short-term cyclical elements
     are critical in short-term ratings, while other factors of major importance
     in bond risk, long-term secular trends for example, may be less important
     over the short run. A short-term rating may also be assigned on an issue
     having a demand feature-variable rate demand obligation. Such ratings will
     be designated as VMIG, SG or, if the demand feature is not rated, as NR.
 
       Moody's short-term ratings are designated Moody's Investment Grade as MIG
     1 or VMIG 1 through MIG 4 or VMIG 4. As the name implies, when Moody's
     assigns a MIG or VMIG rating, all categories define an investment grade
     situation.
 
       MIG 1/VMIG 1. This designation denotes best quality. There is present
     strong protection by established cash flows, superior liquidity support or
     demonstrated broad based access to the market for refinancing.
 
       MIG 2/VMIG 2. This designation denotes high quality. Margins of
     protection are ample although not so large as in the preceding group.
 
       MIG 3/VMIG 3. This designation denotes favorable quality. All security
     elements are accounted for but there is lacking the undeniable strength of
     the preceding grades. Liquidity and cash flow protection may be narrow and
     market access for refinancing is likely to be less well established.
 
       MIG 4/VMIG 4. This designation denotes adequate quality. Protection
     commonly regarded as required of an investment security is present and
     although not distinctly or predominantly speculative, there is specific
     risk.
 
       SG. This designation denotes speculative quality. Debt instruments in
     this category lack margins of protection.
 
     3. TAX-EXEMPT COMMERCIAL PAPER
 
   
       Moody's short-term debt ratings are opinions of the ability of issuers to
     repay punctually promissory obligations not having an original maturity in
     excess of nine months. Moody's makes no representation that such
     obligations are exempt from registration under the Securities Act of 1933,
     nor does it represent that any specific note is a valid obligation of a
     rated issuer or issued in conformity with any applicable law. Obligations
     relying upon support mechanisms such as letters-of-credit and bonds of
     Indemnity are excluded unless explicitly rated.
    
 
       Moody's employs the following three designations, all judged to be
     investment grade, to indicate the relative repayment ability of rated
     issuers:
 
   
        Issuers rated Prime-1 (for related supporting institutions) have a
      superior capacity for repayment of short-term promissory obligations.
      Prime-1 repayment capacity will normally be evidenced by the following
      characteristics:
    
 
   
         - Leading market positions in well established industries.
    
 
   
         - High rates of return on funds employed.
    
 
                                      B-18
<PAGE>   655
 
   
         - Conservative capitalization structures with moderate reliance on debt
           and ample asset protection.
    
 
   
         - Broad margins in earning coverage of fixed financial charges and high
           internal cash generation.
    
 
   
         - Well established access to a range of financial markets and assured
           sources of alternate liquidity.
    
 
   
        Issuers rated Prime-2 (or related supporting institutions) have a strong
      capacity for repayment of short-term promissory obligations. This will
      normally be evidenced by many of the characteristics cited above but to a
      lesser degree. Earnings trends and coverage ratios, while sound, will be
      more subject to variation. Capitalization characteristics, while still
      appropriate, may be more affected by external conditions. Ample alternate
      liquidity is maintained.
    
 
   
        Issuers rated Prime-3 (or related supporting institutions) have an
      acceptable capacity for repayment of short-term promissory obligations.
      The effects of industry characteristics and market composition may be more
      pronounced. Variability in earnings and profitability may result in
      changes in the level of debt protection measurements and the requirement
      for relatively high financial leverage. Adequate alternate liquidity is
      maintained.
    
 
   
        Issuers rated Not Prime do not fall within any of the Prime rating
      categories.

  Each of the trustees holds the same position with each of the funds in the
Fund Complex. As of December 31, 1996, there were 51 funds in the Fund Complex.
Each trustee who is not an affiliated person of VKAC, the Advisers, the
Distributor, ACCESS or Morgan Stanley (each a "Non-Affiliated Trustee") is
compensated by an annual retainer and meeting fees for services to the funds in
the Fund Complex. Each fund in the Fund Complex provides a deferred compensation
plan to its Non-Affiliated Trustees that allows trustees to defer receipt of
their compensation and earn a return on such deferred amounts based upon the
return of the common shares of the funds in the Fund Complex as more fully
described below. Each fund in the Fund Complex also provides a retirement plan
to its Non-Affiliated Trustees that provides Non-Affiliated Trustees with
compensation after retirement, provided that certain eligibility requirements
are met as more fully described below.
    
 
   
  The compensation of each Non-Affiliated Trustee from each fund in the Fund
Complex advised by Advisory Corp. (each a "VK Fund" and collectively the "VK
Funds") includes an annual retainer in an amount equal to $2,500 per calendar
year, due in four quarterly installments on the first business day of each
calendar quarter. Each Non-Affiliated Trustee receives a per meeting fee from
each VK Fund in the amount of $125 per regular quarterly meeting attended by the
Non-Affiliated Trustee, due on the date of such meeting, plus reasonable
expenses incurred by the Non-Affiliated Trustee in connection with his or her
services as a trustee. Each Non-Affiliated Trustee receives a per meeting fee
from each VK Fund in the amount of $125 per special meeting attended by the
Non-Affiliated Trustee, due on the date of such meeting, plus reasonable
expenses incurred by the Non-Affiliated Trustee in connection with his or her
services as a trustee, provided that no compensation will be paid in connection
with certain telephonic special meetings.
    
 
   
  The compensation of each Non-Affiliated Trustee from the funds in the Fund
Complex advised by Asset Management (each an "AC Fund" or collectively the "AC
Funds") includes an annual retainer in an amount equal to $35,000 per calendar
year, due in four quarterly installments on the first business day of each
calendar quarter. The AC Funds pay each Non-Affiliated Trustee a per meeting fee
in the amount of $2,000 per regular quarterly meeting attended by the
Non-Affiliated Trustee, due on the date of such meeting, plus reasonable
    
 
                                      B-23
<PAGE>   660
 
   
expenses incurred by the Non-Affiliated Trustee in connection with his or her
services as a trustee. Payment of the annual retainer and the regular meeting
fee is allocated among the AC Funds (i) 50% on the basis of the relative net
assets of each AC Fund to the aggregate net assets of all the AC Funds and (ii)
50% equally to each AC Fund, in each case as of the last business day of the
preceding calendar quarter. Each AC Fund which is the subject of a special
meeting of the trustees generally pays each Non-Affiliated Trustee a per meeting
fee in the amount of $125 per special meeting attended by the Non-Affiliated
Trustee, due on the date of such meeting, plus reasonable expenses incurred by
the Non-Affiliated Trustee in connection with his or her services as a trustee,
provided that no compensation will be paid in connection with certain telephonic
special meetings.
    
 
   
  The trustees approved an aggregate compensation cap with respect to funds in
the Fund Complex of $84,000 per Non-Affiliated Trustee per year (excluding any
retirement benefits) for the period July 22, 1995 through December 31, 1996,
subject to the net assets and the number of funds in the Fund Complex as of July
21, 1995 and certain other exceptions. For the calendar year ended December 31,
1996, certain trustees received aggregate compensation from the funds in the
Fund Complex over $84,000 due to compensation received but not subject to the
cap, including compensation from new funds added to the Fund Complex after July
22, 1995 and certain special meetings in 1996. In addition, each of Advisory
Corp. or Asset Management, as the case may be, agreed to reimburse each fund in
the Fund Complex through December 31, 1996 for any increase in the aggregate
trustee's compensation over the aggregate compensation paid by such fund in its
1994 fiscal year, provided that if a fund did not exist for the entire 1994
fiscal year appropriate adjustments will be made.
    
 
   
  Each Non-Affiliated Trustee generally can elect to defer receipt of all or a
portion of the compensation earned by such Non-Affiliated Trustee until
retirement. Amounts deferred are retained by the Fund and earn a rate of return
determined by reference to the return on the common shares of such Fund or other
funds in the Fund Complex as selected by the respective Non-Affiliated Trustee,
with the same economic effect as if such Non-Affiliated Trustee had invested in
one or more funds in the Fund Complex. To the extent permitted by the 1940 Act,
the Fund may invest in securities of those funds selected by the Non-Affiliated
Trustees in order to match the deferred compensation obligation. The deferred
compensation plan is not funded and obligations thereunder represent general
unsecured claims against the general assets of the Fund.
    
 
   
  Each fund in the Fund Complex has adopted a retirement plan. Under the Fund's
retirement plan, a Non-Affiliated Trustee who is receiving trustee's
compensation from the Fund prior to such Non-Affiliated Trustee's retirement,
has at least 10 years of service (including years of service prior to adoption
of the retirement plan) and retires at or after attaining the age of 60, is
eligible to receive a retirement benefit equal to $2,500 per year for each of
the ten years following such trustee's retirement from the Fund. Trustees
retiring prior to the age of 60 or with fewer than 10 years but more than 5
years of service may receive reduced retirement benefits from the Fund. Each
trustee has served as a member of the Board of Trustees since he or she was
first appointed or elected in the year set forth below. The retirement plan
contains a Fund Complex retirement benefit cap of $60,000 per year. Asset
Management has reimbursed each AC Fund for the expenses related to the
retirement plan through December 31, 1996.
    
 
   
  Additional information regarding compensation and benefits for trustees is set
forth below. As indicated in the notes accompanying the table, the amounts
relate to either the Trust's most recently completed fiscal year or the Fund
Complex' most recently completed calendar year ended December 31, 1996.

*  Currently a member of the Board of Trustees. Mr. Phillip B. Rooney also is a
   current member of the Board of Trustees but is not included in the
   compensation table because he did not serve on the Board of Trustees or
   receive any compensation from the Trust prior to April 14, 1997. Messrs.
   McDonnell and Powell, also trustees of the Trust during all or a portion of
   the Trust's last fiscal year, are not included in the compensation table
   because they are affiliated persons of the Advisers and are not eligible for
   compensation or retirement benefits from the Trust.
    
 
   
(1) Persons not designated by an asterisk are not currently members of the Board
    of Trustees, but were members of the Board of Trustees during the Trust's
    most recently completed fiscal year. Messrs. Gaughan and Rees retired from
    the Board of Trustees on January 26, 1996 and January 29, 1996,
    respectively. Mr. Sheehan was removed from the Board of Trustees effective
    January 29, 1996. Messrs. Hilsman, Miller and Woodside retired from the
    Board of Trustees on December 31, 1996.
    
 
   
(2) The amounts shown in this column represent the aggregate compensation before
    deferral from all eight series of the Trust, including the Fund, with
    respect to the Trust's fiscal year ended December 31, 1996. The detail of
    aggregate compensation before deferral for each series, including the Fund,
    are shown in Table A below. Certain trustees deferred compensation from the
    Trust during the fiscal year ended December 31, 1996; the aggregate
    compensation deferred from all eight series of the Trust, including the
    Fund, is as follows: Mr. Branagan, $5,750; Mr. Gaughan, $3,750; Ms. Heagy,
    $15,000; Mr. Kennedy, $9,500; Mr. Miller, $20,000; Mr. Nelson, $20,000; Mr.
    Robinson, $18,000; and Mr. Whalen, $19,625. The details of amounts deferred
    for each series, including the Fund, are shown in Table B below. Amounts
    deferred are retained by the respective fund and earn a rate of return
    determined by reference to either the return on the common shares of such
    fund or other funds in the Fund Complex as selected by the respective
    Non-Affiliated Trustee, with the same economic effect as if such
    Non-Affiliated Trustee had invested in one or more funds in the Fund
    Complex. To the extent permitted by the 1940 Act, each fund may invest in
    securities of those funds selected by the Non-Affiliated Trustees in order
    to match the deferred compensation obligation. The cumulative deferred
    compensation (including interest) accrued with respect to each trustee from
    all eight series of the Trust, including the Fund, as of the Trust's fiscal
    year ended December 31, 1996 is as follows: Mr. Branagan, $5,678; Mr.
    Gaughan, $20,094; Ms. Heagy, $20,472; Mr. Kennedy, $47,294; Mr. Miller,
    $55,827; Mr. Nelson, $57,771; Mr. Robinson, $54,847; and Mr. Whalen,
    $49,269. The details of cumulative deferred compensation (including
    interest) for each

    series, including the Fund, are shown in Table C below. The deferred
    compensation plan is described above the Compensation Table.
    
 
   
(3) The amounts shown in this column represent the retirement benefits accrued
    by all eight series of the Trust, including the Fund, with respect to the
    Trust's fiscal year ended December 31, 1996. The details of retirement
    benefits accrued for each series, including the Fund, are shown in Table D
    below. The retirement plan is described above the Compensation Table.
    
 
   
(4) This is the estimated maximum annual benefits payable by the Trust in each
    year of the 10-year period commencing in the year of such trustee's
    retirement from the Trust. The estimated maximum annual benefit, except for
    trustees who have retired or are near retirement, is based upon $2,500 per
    series assuming: the trustee has 10 or more years of service on the Board of
    Trustees (including years of service prior to the adoption of the retirement
    plan) and retires at or after attaining the age of 60. Trustees retiring
    prior to the age of 60 or with fewer than 10 years of service for a series
    of the Trust may receive reduced retirement benefits from such series. The
    actual annual benefit may be less if the trustee is subject to the Fund
    Complex retirement benefit cap or if the trustee is not fully vested at the
    time of retirement. Each Non-Affiliated Trustee of the Board of Trustees has
    served as a member of the Board of Trustees since he or she was first
    appointed or elected in the year set forth in Table E below.
    
 
   
(5) The amounts shown in this column represent the aggregate compensation paid
    by all 51 of the investment companies in the Fund Complex as of December 31,
    1996 before deferral by the trustees under the deferred compensation plan.
    Certain trustees deferred all or a portion of their aggregate compensation
    from the Fund Complex during the calendar year ended December 31, 1996. The
    deferred compensation earns a rate of return determined by reference to the
    return on the shares of the funds in the Fund Complex as selected by the
    respective Non-Affiliated Trustee, with the same economic effect as if such
    Non-Affiliated Trustee had invested in one or more funds in the Fund
    Complex. To the extent permitted by the 1940 Act, the Fund may invest in
    securities of those investment companies selected by the Non-Affiliated
    Trustees in order to match the deferred compensation obligation. The
    trustees' Fund Complex compensation cap covered the period July 22, 1995
    through December 31, 1996. For the calendar year ended December 31, 1996,
    certain trustees received compensation over $84,000 in the aggregate due to
    compensation received but not subject to the cap, including compensation
    from new funds added to the Fund Complex after July 22, 1995 and certain
    special meetings in 1996. The Advisers and their affiliates also serve as
    investment adviser for other investment companies; however, with the
    exception of Messrs. McDonnell, Powell and Whalen, the trustees were not
    trustees of such investment companies. Combining the Fund Complex with other
    investment companies advised by the Advisers and their affiliates, Mr.
    Whalen received Total Compensation of $243,375 during the calendar year
    ended December 31, 1996.
    
 
   
  As of April 4, 1997, the trustees and officers of the Fund as a group owned
less than 1% of the shares of the Fund.

as trustees of the Trust and officers of the Fund if duly elected to such
positions.
    
 
  The agreement provides that the Adviser shall not be liable for any error of
judgment or of law, or for any loss suffered by the Fund in connection with the
matters to which the agreement relates, except a loss resulting from willful
misfeasance, bad faith, or gross negligence on the part of the Adviser in the
performance of its obligations and duties, or by reason of its reckless
disregard of its obligations and duties under the agreement.
 
  The Adviser's activities are subject to the review and supervision of the
Board of Trustees of the Trust, of which the Fund is a series, to whom the
Adviser renders periodic reports of the Fund's investment activities.
 
  The investment advisory agreement for the Fund will continue in effect from
year to year if specifically approved by the trustees of the Trust, of which the
Fund is a separate series (or by the Fund's shareholders), and by the
disinterested trustees in compliance with the requirements of the 1940 Act. The
agreement may be terminated without penalty upon 60 days' written notice by
either party thereto and will automatically terminate in the event of
assignment.
 
  The investment advisory agreement specifies that the Adviser will reimburse
the Fund for annual expenses of the Fund which exceed the most stringent limit
prescribed by any state in which the Fund's shares are offered for sale.
Currently, the most stringent limit in any state would require such
reimbursement to the extent that aggregate operating expenses of the Fund
(excluding interest, taxes and other expenses which may be excludable under
applicable state law) exceed in any fiscal year 2 1/2% of the average annual net
assets of the Fund up to $30 million, 2% of the average annual net assets of the
Fund of the next $70 million, and 1 1/2% of
 
                                      B-29
<PAGE>   666
 
the remaining average annual net assets of the Fund. In addition to making any
required reimbursements, the Adviser may in its discretion, but is not obligated
to, waive all or any portion of its fee or assume all or any portion of the
expenses of the Fund.
 
   
  For the years ending December 31, 1996 and December 31, 1995 and the period
ended December 31, 1994, the Fund paid $176,896, $0 and $0, respectively.
    
 
OTHER AGREEMENTS
 
   
  ACCOUNTING SERVICES AGREEMENT.  The Fund has also entered into an accounting
services agreement pursuant to which the Adviser provides accounting services
supplementary to those provided by the Custodian. Such services are expected to
enable the Fund to more closely monitor and maintain its accounts and records.
The Fund shares equally with the other Van Kampen American Capital mutual funds
in the cost of providing such services, with 25% of such costs shared
proportionately based on the respective number of classes of securities issued
per fund and the remaining 75% of such cost based proportionally on their
respective net assets per fund.
    
 
   
  For the years ending December 31, 1996 and December 31, 1995 and the period
ended December 31, 1994, the Fund paid expenses of approximately $8,900, $7,300
and $4,100, respectively, representing the Adviser's cost of providing
accounting services.
    
 
  LEGAL SERVICES AGREEMENT.  The Fund and each of the other Van Kampen American
Capital funds advised by the VK Adviser and distributed by the Distributor have
entered into Legal Services Agreements pursuant to which Van Kampen American
Capital provides legal services, including without limitation: maintenance of
the funds' minute books and records, preparation and oversight of the funds'
regulatory reports, and other information provided to shareholders, as well as
responding to day-to-day legal issues on behalf of the funds. Payment by the
Fund for such services is made on a cost basis for the salary and salary related
benefits, including but not limited to bonuses, group insurances and other
regular wages for the employment of personnel, as well as overhead and the
expenses related to the office space and the equipment necessary to render the
legal services. Other funds distributed by the Distributor also receive legal
services from Van Kampen American Capital. Of the total costs for legal services
provided to funds distributed by the Distributor, one half of such costs are
allocated equally to each fund and the remaining one half of such costs are
allocated to specific funds based on monthly time records.
 
   
  For the years ending December 31, 1996 and December 31, 1995 and the period
ended December 31, 1994, the Fund paid expenses of approximately $7,800, $8,200
and $8,086, respectively, representing Van Kampen American Capital's cost of
providing legal services.
    
 
   
                     CUSTODIAN AND INDEPENDENT ACCOUNTANTS
    
 
  State Street Bank and Trust Company, 225 Franklin Street, P.O. Box 1713,
Boston, MA 02105-1713, is the custodian of the Fund and has custody of all
securities and cash of the Fund. The custodian, among other things, attends to
the collection of principal and income, and payment for and collection of
proceeds of securities bought and sold by the Fund.
 
   
  The independent accountants for the Fund are KPMG Peat Marwick LLP, Chicago,
Illinois. The selection of independent accountants will be subject to
ratification by the shareholders of the Fund at any annual meeting of
shareholders.
    
 
                PORTFOLIO TRANSACTIONS AND BROKERAGE ALLOCATION
 
  The Adviser will place orders for portfolio transactions for the Fund with
broker-dealer firms giving consideration to the quality, quantity and nature of
each firm's professional services. These services include execution, clearance
procedures, wire service quotations and statistical and other research
information provided to the Fund, or the Adviser, including quotations necessary
to determine the value of the Fund's net assets. Any research benefits derived
are available for all clients of the Adviser. Since statistical and other
research information is only supplementary to the research efforts of the
Adviser to the Fund and still must be
 
                                      B-30
<PAGE>   667
 
analyzed and reviewed by its staff, the receipt of research information is not
expected to materially reduce its expenses.
 
  If it is believed to be in the best interests of the Fund, the Adviser may
place portfolio transactions with brokers who provide the types of service
described above, even if it means the Fund will have to pay a higher commission
(or, if the broker's profit is part of the cost of the security, will have to
pay a higher price for the security), than would be the case if no weight were
given to the broker's furnishing of those services. This will be done, however,
only if, in the opinion of the Fund's Adviser, the amount of additional
commission or increased cost is reasonable in relation to the value of the
services.
 
  In selecting among the firms believed to meet the criteria for handling a
particular transaction, the Fund's Adviser may take into consideration that
certain firms (i) provide market, statistical or other research information to
the Fund and the Adviser, (ii) have sold or are selling shares of the Fund and
that certain firms and (iii) may select firms that are affiliated with the Fund,
the Adviser, or its distributor and other principal underwriters. If purchases
or sales of securities of the Fund and of one or more other investment companies
or clients supervised by the Adviser are considered at or about the same time,
transactions in such securities will be allocated among the several investment
companies and clients in a manner deemed equitable to all by the Adviser, taking
into account the respective sizes of the Fund and other investment companies and
clients and the amount of securities to be purchased or sold. Although it is
possible that in some cases this procedure could have a detrimental effect on
the price or volume of the security as far as the Fund is concerned, it is also
possible that the ability to participate in volume transactions and to negotiate
lower brokerage commissions will be beneficial to the Fund.
 
  While the Adviser will be primarily responsible for the placement of the
Fund's business, the policies and practices in this regard must be consistent
with the foregoing and will at all times be subject to review by the trustees of
the Trust, of which the Fund is a separate series.
 
  The trustees have adopted certain policies incorporating the standards of Rule
17e-1 issued by the SEC under the 1940 Act which requires that the commissions
paid to the Distributor and other affiliates of the Fund must be reasonable and
fair compared to the commissions, fees or other remuneration received or to be
received by other brokers in connection with comparable transactions involving
similar securities during a comparable period of time. The rule and procedures
also contain review requirements and require the Adviser to furnish reports to
the trustees and to maintain records in connection with such reviews. After
consideration of all factors deemed relevant, the trustees will consider from
time to time whether the advisory fee for the Fund will be reduced by all or a
portion of the brokerage commission given to affiliated brokers.
 
  State securities laws may differ from the interpretations of federal law
expressed herein, and banks and financial institutions may be required to
register as dealers pursuant to state law.
 
                             TAX STATUS OF THE FUND
 
   
  The Trust and any of its series, including the Fund, will be treated as
separate corporations for federal income tax purposes. The Fund intends to
qualify each year and to elect to be treated as a regulated investment company
under the Code. If the Fund so qualifies and distributes each year to its
shareholders at least 90% of its net investment income (including tax-exempt
interest, taxable income and net short-term capital gain, but not net capital
gains, which are the excess of long-term capital gains over net short-term
capital losses) in each year, it will not be required to pay federal income
taxes on any income distributed to shareholders. The Fund intends to distribute
at least the minimum amount of net investment income necessary to satisfy the
90% distribution requirement. The Fund will not be subject to federal income tax
on any net capital gains distributed to shareholders.

  Pursuant to a distribution agreement, the Distributor will purchase shares of
the Fund for resale to the public, either directly or through securities
dealers, and is obligated to purchase only those shares for which it has
received purchase orders. Shares of the Fund may not be purchased from the
Distributor for consideration other than cash. A discussion of how to purchase
and redeem the Fund's shares and how the Fund's shares are priced is contained
in the Prospectus.
    
 
   
                         DISTRIBUTION AND SERVICE PLANS
    
 
  The Fund has adopted a distribution plan (the "Distribution Plan") with
respect to each class of its shares pursuant to Rule 12b-1 under the 1940 Act.
The Fund also has adopted a service plan (the "Service Plan") with respect to
each class of its shares. The Distribution Plan and the Service Plan sometimes
are referred to herein as the "Plans." The Plans provide that the Fund may spend
a portion of the Fund's average daily net assets attributable to each class of
shares in connection with distribution of the respective class of shares and in
connection with the provision of ongoing services to shareholders of such class,
respectively. The Distribution Plan and the Service Plan are being implemented
through an agreement (the "Distribution and Service Agreement") with the
Distributor of each class of the Fund's shares, sub-agreements between the
Distributor and members of the NASD acting as securities dealers and NASD
members or eligible non-members acting as brokers or agents and similar
agreements between the Fund and financial intermediaries acting as brokers
(collectively, "Selling Agreements") that may provide for their customers or
clients certain services or assistance, which may include, but not be limited
to, processing purchase and redemption transactions, establishing and
maintaining shareholder accounts regarding the Fund, and such other services as
may be agreed to from time to time and as may be permitted by applicable
statute, rule or regulation. Brokers, dealers and financial intermediaries that
have entered into sub-agreements with the Distributor and sell shares of the
Fund are referred to herein as "financial intermediaries."
 
                                      B-32
<PAGE>   669
 
   
  The Distributor must submit quarterly reports to the Board of Trustees of the
Trust, of which the Fund is a series, setting forth separately by class of
shares all amounts paid under the Distribution Plan and the purposes for which
such expenditures were made, together with such other information as from time
to time is reasonably requested by the Trustees. The Plans provide that they
will continue in full force and effect from year to year so long as such
continuance is specifically approved by a vote of the Trustees, and also by a
vote of the disinterested Trustees, cast in person at a meeting called for the
purpose of voting on the Plans. Each of the Plans may not be amended to increase
materially the amount to be spent for the services described therein with
respect to either class of shares without approval by a vote of a majority of
the outstanding voting shares of such class, and all material amendments to
either of the Plans must be approved by the Trustees and also by the
disinterested Trustees. Each of the Plans may be terminated with respect to
either class of shares at any time by a vote of a majority of the disinterested
Trustees or by a vote of a majority of the outstanding voting shares of such
class.
    
 
   
  For the fiscal year ended December 31, 1996, the Fund's aggregate expenses
under the Plans for Class A shares were $34,938 or 0.25% of the Class A shares'
average net assets. Such expenses were paid to reimburse the Distributor for
payments made to financial intermediaries for servicing Fund shareholders and
for administering the Plans. For the fiscal year ended December 31, 1996, the
Fund's aggregate expenses under the Plans for Class B shares were $167,722 or
1.00% of the Class B shares' average net assets. Such expenses were paid to
reimburse the Distributor for the following payments: $125,792 for commissions
and transaction fees paid to financial intermediaries in respect of sales of
Class B shares of the Fund and $41,930 for fees paid to financial intermediaries
for servicing Class B shareholders and administering the Plans. For the fiscal
year ended December 31, 1996, the Fund's aggregate expenses under the Plans for
Class C shares were $46,319 or 1.00% of the Class C shares' average net assets.
Such expenses were paid to reimburse the Distributor for the following payments:
$23,875 for commissions and transaction fees paid to financial intermediaries in
respect of sales of Class C shares of the Fund and $22,444 for fees paid to
financial intermediaries for servicing Class C shareholders and administering
the Plans.
    
 
                                 LEGAL COUNSEL
 
   
  Counsel to the Fund is Skadden, Arps, Slate, Meagher & Flom (Illinois).
    
 
                            PERFORMANCE INFORMATION
 
  The Fund's yield quotation is determined on a monthly basis with respect to
the immediately preceding 30 day period, and yield is computed by dividing the
Fund's net investment income per share of a given class earned during such
period by the Fund's maximum offering price (including, with respect to the
Class A Shares, the maximum initial sales charge) per share of such class on the
last day of such period. The Fund's net investment income per share is
determined by taking the interest attributable to a given class of shares earned
by the Fund during the period, subtracting the expenses attributable to a given
class of shares accrued for the period (net of any reimbursements), and dividing
the result by the average daily number of the shares of each class outstanding
during the period that were entitled to receive dividends. The yield calculation
formula assumes net investment income is earned and reinvested at a constant
rate and annualized at the end of a six month period. Yield will be computed
separately for each class of shares. CDSC Shares may be subject to a contingent
deferred sales charge. Yield quotations do not reflect the imposition of a
contingent deferred sales charge, and if any such contingent deferred sales
charge imposed at the time of redemption were reflected, it would reduce the
performance quoted.
 
  Tax-equivalent yield demonstrates the taxable yield required to produce an
after-tax yield equivalent to that of the Fund's yield. The Fund's
tax-equivalent yield quotation for a 30 day period as described above is
computed by dividing that portion of the yield of the Fund (as computed above)
which is tax-exempt by a percentage equal to 100% minus a stated percentage
income tax rate and adding the result to that portion of the Fund's yield, if
any, that is not tax-exempt.
 
  The Fund calculates average compounded total return by determining the
redemption value (less any applicable contingent deferred sales charge) at the
end of specified periods (after adding back all dividends
 
                                      B-33
<PAGE>   670
 
and other distributions made during the period) of a $1,000 investment in a
given class of shares of the Fund (less the maximum sales charge, if any) at the
beginning of the period, annualizing the increase or decrease over the specified
period with respect to such initial investment and expressing the result as a
percentage. Average compounded total return will be computed separately for each
class of shares.
 
  Total return figures utilized by the Fund are based on historical performance
and are not intended to indicate future performance. Total return and net asset
value per share of a given class can be expected to fluctuate over time, and
accordingly upon redemption a shareholder's shares may be worth more or less
than their original cost.
 
  The Fund may, in supplemental sales literature, advertise non-standardized
total return figures representing the cumulative, non-annualized total return of
each class of shares of the Fund from a given date to a subsequent given date.
Cumulative non-standardized total return is calculated by measuring the value of
an initial investment in a given class of shares of the Fund at a given time,
deducting the maximum initial sales charge, if any, determining the value of all
subsequent reinvested distributions, and dividing the net change in the value of
the investment as of the end of the period by the amount of the initial
investment and expressing the result as a percentage. Non-standardized total
return will be calculated separately for each class of shares. Non-standardized
total return calculations do not reflect the imposition of a contingent deferred
sales charge, and if any such contingent deferred sales charge with respect to
the CDSC Shares imposed at the time of redemption were reflected, it would
reduce the performance quoted.
 
  From time to time marketing materials may provide a portfolio manager update,
an adviser update or discuss general economic conditions and outlooks. The
Fund's marketing materials may also show the Fund's asset class diversification,
top five sectors, ten largest holdings and other Fund asset structures, such as
duration, maturity, coupon, NAV, rating breakdown, AMT exposure and number of
issues in the portfolio. Materials may also mention how Van Kampen American
Capital believes the Fund compares relative to other Van Kampen American Capital
funds. Materials may also discuss the Dalbar Financial Services study from 1984
to 1994 which studied investor cash flow into and out of all types of mutual
funds. The ten year study found that investors who bought mutual fund shares and
held such shares outperformed investors who bought and sold. The Dalbar study
conclusions were consistent regardless of if shareholders purchased their funds
in direct or sales force distribution channels. The study showed that investors
working with a professional representative have tended over time to earn higher
returns than those who invested directly. The Fund will also be marketed on the
Internet.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
The Board of Trustees and Shareholders of
Van Kampen American Capital Intermediate Term Municipal Income Fund:
 
We have audited the accompanying statement of assets and liabilities of Van
Kampen American Capital Intermediate Term Municipal Income Fund (the "Fund"),
including the portfolio of investments, as of December 31, 1996, and the related
statement of operations for the year then ended, the statement of changes in net
assets for each of the two years in the period then ended, and the financial
highlights for each of the periods presented. These financial statements and
financial highlights are the responsibility of the Fund's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits.
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of
December 31, 1996, by correspondence with the custodian and brokers. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.
    In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of Van
Kampen American Capital Intermediate Term Municipal Income Fund as of December
31, 1996, the results of its operations for the year then ended, the changes in
its net assets for each of the two years in the period then ended, and the
financial highlights for each of the periods presented, in conformity with
generally accepted accounting principles.

*Zero coupon bond
</TABLE>
 
(a) At December 31, 1996, for federal income tax purposes cost is $33,831,921;
    the aggregate gross unrealized appreciation is $1,810,859 and the aggregate
    gross unrealized depreciation is $28,588, resulting in net unrealized
    appreciation of $1,782,271.
 
(b) Securities purchased on a when issued or delayed delivery basis.
 
(c) Assets segregated as collateral for when issued or delayed delivery purchase
    commitments.
 
(d) An Embedded Swap security includes a swap component such that the fixed
    coupon component of the underlying bond is adjusted by the difference
    between the security's fixed swap rate and the floating swap index. As the
    floating rate rises, the coupon is reduced. Conversely, as the floating rate
    declines, the coupon is increased. The price of these securities may be more
    volatile than the price of a comparable fixed rate security. These are
    typically used by the Fund to enhance the yield of the portfolio. These
    derivative instruments are marked to market each day with the change in
    value reflected in the unrealized appreciation/depreciation on investments.
    Upon disposition, a realized gain or loss is recognized accordingly.

1. SIGNIFICANT ACCOUNTING POLICIES
 
Van Kampen American Capital Intermediate Term Municipal Income Fund (the "Fund")
is organized as a series of Van Kampen American Capital Tax Free Trust (the
"Trust"), a Delaware business trust, and is registered as a diversified open-end
management investment company under the Investment Company Act of 1940, as
amended. The Fund's investment objective is to seek a high level of current
income exempt from federal income tax, consistent with preservation of capital.
The Fund commenced investment operations on May 28, 1993 with two classes of
common shares, Class A and Class B shares. The distribution of the Fund's Class
C shares commenced on October 19, 1993.
 
    The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. The
preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amount of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.
 
A. SECURITY VALUATION--Investments are stated at value using market quotations
or, if such valuations are not available, estimates obtained from yield data
relating to instruments or securities with similar characteristics in accordance
with procedures established in good faith by the Board of Trustees. Short-term
securities with remaining maturities of 60 days or less are valued at amortized
cost.
 
B. SECURITY TRANSACTIONS--Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis. The
Fund may purchase and sell securities on a "when issued" or "delayed delivery"
basis, with settlement to occur at a later date. The value of the security so
purchased is subject to market fluctuations during this period. The Fund will
maintain, in a segregated account with its custodian, assets having an aggregate
value at least equal to the amount of the when issued or delayed delivery
purchase commitments until payment is made.
 
C. INVESTMENT INCOME--Interest income is recorded on an accrual basis. Bond
premium and original issue discount are amortized over the expected life of each
applicable security.

D. ORGANIZATIONAL EXPENSES--The Fund has reimbursed Van Kampen American Capital
Distributors, Inc. or its affiliates (collectively "VKAC") for costs incurred in
connection with the Fund's organization in the amount of $60,000. These costs
are being amortized on a straight line basis over the 60 month period ending May
27, 1998. Van Kampen American Capital Investment Advisory Corp. (the "Adviser")
has agreed that in the event any of the initial shares of the Fund originally
purchased by VKAC are redeemed during the amortization period, the Fund will be
reimbursed for any unamortized organizational expenses in the same proportion as
the number of shares redeemed bears to the number of initial shares held at the
time of redemption.
 
E. FEDERAL INCOME TAXES--It is the Fund's policy to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no provision for federal income taxes is required.
 
    The Fund intends to utilize provisions of the federal income tax laws which
allow it to carry a realized capital loss forward for eight years following the
year of loss and offset such losses against any future realized capital gains.
At December 31, 1996, the Fund had an accumulated capital loss carryforward for
tax purposes of $685,887 which will expire between December 31, 2002 and
December 31, 2003.
 
F. DISTRIBUTION OF INCOME AND GAINS--The Fund declares daily and pays monthly
dividends from net investment income. Net realized gains, if any, are
distributed annually. Distributions from net realized gains for book purposes
may include short-term capital gains, which are included as ordinary income for
tax purposes.
 
    For the year ended December 31, 1996, 100% of the income distributions made
by the Fund were exempt from federal income taxes.
 
2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES
 
Under the terms of the Fund's Investment Advisory Agreement, the Adviser will
provide investment advice and facilities to the Fund for an annual fee payable

                             THE FUND AND THE TRUST
 
   
  Van Kampen American Capital Florida Insured Tax Free Income Fund (the "Fund")
is a separate series of the Trust, an open-end non-diversified management
investment company. At present, the Fund, Van Kampen American Capital Insured
Tax Free Income Fund, Van Kampen American Capital Tax Free High Income Fund, Van
Kampen American Capital Municipal Income Fund, Van Kampen American Capital
Intermediate Term Municipal Income Fund, Van Kampen American Capital California
Insured Tax Free Fund, Van Kampen American Capital New Jersey Tax Free Income
Fund and Van Kampen American Capital New York Tax Free Fund have each been
organized as a series of the Trust and have commenced investment operations. Van
Kampen American Capital California Tax Free Income Fund, Van Kampen American
Capital Michigan Tax Free Income Fund, Van Kampen American Capital Missouri Tax
Free Income Fund and Van Kampen American Capital Ohio Tax Free Income Fund have
each been organized as a series of the Trust but have not commenced investment
operations. Other series may be organized and offered in the future.
    
 
  The Trust is an unincorporated business trust established under the laws of
the State of Delaware by an Agreement and Declaration of Trust (the "Declaration
of Trust") dated May 10, 1995. The Declaration of Trust permits the Trustees to
create one or more separate investment portfolios and issue a series of shares
for each portfolio. The Trustees can further sub-divide each series of shares
into one or more classes of shares for each portfolio. The Trust can issue an
unlimited number of shares, par value $0.01 (prior to July 31, 1995, the shares
had no par value). Each share represents an equal proportionate interest in the
assets of the series with each other share in such series and no interest in any
other series. No series is subject to the liabilities of any other series. The
Declaration of Trust provides that shareholders are not liable for any
liabilities of the Trust or any of its series, requires inclusion of a clause to
that effect in every agreement entered into by the Trust or any of its series
and indemnifies shareholders against any such liability. The Fund was originally
organized in 1994 under the name Van Kampen Merritt Florida Insured Tax Free
Fund as a sub-trust of the Van Kampen Merritt Tax Free Trust, a Massachusetts
business trust. The Fund was reorganized as a series of the Trust and adopted
its present name as of July 31, 1995.
 
  Shares of the Trust entitle their holders to one vote per share; however,
separate votes are taken by each series on matters affecting an individual
series. For example, a change in investment policy for a series would be voted
upon by shareholders of only the series involved. Except as described in the
prospectus, shares do not have cumulative voting rights, preemptive rights or
any conversion or exchange rights. The Trust does not contemplate holding
regular meetings of shareholders to elect Trustees or otherwise. However, the
holders of 10% or more of the outstanding shares may by written request require
a meeting to consider the removal of Trustees by a vote of two-thirds of the
shares then outstanding cast in person or by proxy at such meeting.
 
  The Trustees may amend the Declaration of Trust (including with respect to any
series) in any manner without shareholder approval, except that the Trustees may
not adopt any amendment adversely affecting the rights of shareholders of any
series without approval by a majority of the shares of each affected series
present at a meeting of shareholders (or such higher vote as may be required by
the Investment Company Act of 1940, as amended (the "1940 Act") or other
applicable law) and except that the Trustees cannot amend the Declaration of
Trust to impose any liability on shareholders, make any assessment on shares or
impose liabilities on the Trustees without approval from each affected
shareholder or Trustee, as the case may be.
 
  Statements contained in this Statement of Additional Information as to the
contents of any contract or other document referred to are not necessarily
complete, and, in each instance, reference is made to the copy of such contract
or other document filed as an exhibit to the Registration Statement of which
this Statement of Additional Information forms a part, each such statement being
qualified in all respects by such reference.
 
                      INVESTMENT POLICIES AND RESTRICTIONS
 
  The investment objective of the Fund is set forth in the Prospectus under the
caption "Investment Objective and Policies." There can be no assurance that the
Fund will achieve its investment objective.
 
                                       B-2
<PAGE>   691
 
  Fundamental investment restrictions limiting the investments of the Fund
provide that the Fund may not:
 
   
   1. Invest more than 25% of its assets in a single industry; however, as
      described in the Prospectus, the Fund may from time to time invest more
      than 25% of its assets in a particular segment of the municipal bond
      market; however, the Fund will not invest more than 25% of its assets in
      industrial development bonds in a single industry, except that the Fund
      may purchase securities of other investment companies to the extent
      permitted by (i) the 1940 Act, as amended from time to time, (ii) the
      rules and regulations promulgated by the SEC under the 1940 Act, as
      amended from time to time, or (iii) an exemption or other relief from the
      provisions of the 1940 Act.
    
 
   2. Borrow money, except from banks for temporary purposes and then in amounts
      not in excess of 5% of the total asset value of the Fund, or mortgage,
      pledge, or hypothecate any assets except in connection with a borrowing
      and in amounts not in excess of 10% of the total asset value of the Fund.
      Borrowings may not be made for investment leverage, but only to enable the
      Fund to satisfy redemption requests where liquidation of portfolio
      securities is considered disadvantageous or inconvenient. In this
      connection, the Fund will not purchase portfolio securities during any
      period that such borrowings exceed 5% of the total asset value of the
      Fund. Notwithstanding this investment restriction, the Fund may enter into
      when issued and delayed delivery transactions as described in the
      Prospectus.
 
   3. Make loans of money or property to any person, except to the extent the
      securities in which the Fund may invest are considered to be loans and
      except that the Fund may lend money or property in connection with
      maintenance of the value of, or the Fund's interest with respect to, the
      securities owned by the Fund.
 
   4. Buy any securities "on margin." Neither the deposit of initial or
      maintenance margin in connection with hedging transactions nor short term
      credits as may be necessary for the clearance of transactions is
      considered the purchase of a security on margin.
 
   5. Sell any securities "short," write, purchase or sell puts, calls or
      combinations thereof, or purchase or sell interest rate or other financial
      futures or index contracts or related options, except in connection with
      Strategic Transactions in accordance with the requirements of the SEC and
      the Commodity Futures Trading Commission.
 
   6. Act as an underwriter of securities, except to the extent the Fund may be
      deemed to be an underwriter in connection with the sale of securities held
      in its portfolio.
 
   
   7. Make investments for the purpose of exercising control or participation in
      management, except to the extent that exercise by the Fund of its rights
      under agreements related to securities owned by the Fund would be deemed
      to constitute such control or participation, except that the Fund may
      purchase securities of other investment companies to the extent permitted
      by (i) the 1940 Act, as amended from time to time, (ii) the rules and
      regulations promulgated by the SEC under the 1940 Act, as amended from
      time to time, or (iii) an exemption or other relief from the provisions of
      the 1940 Act.
    
 
   
   8. Invest in securities issued by other investment companies except as part
      of a merger, reorganization or other acquisition and extent permitted by
      (i) the 1940 Act, as amended from time to time, (ii) the rules and
      regulations promulgated by the SEC under the 1940 Act, as amended from
      time to time, or (iii) an exemption or other relief from the provisions of
      the 1940 Act.
    
 
   9. Invest in oil, gas or mineral leases or in equity interests in oil, gas,
      or other mineral exploration or development programs, except pursuant to
      the exercise by the Fund of its rights under agreements relating to
      municipal securities.
 
  10. Purchase or sell real estate, commodities or commodity contracts, except
      to the extent the securities the Fund may invest in are considered to be
      interest in real estate, commodities or commodity contracts or to the
      extent the Fund exercises its rights under agreements relating to such
      securities (in which case the Fund may own, hold, foreclose, liquidate or
      otherwise dispose of real estate acquired as a result of a
 
                                       B-3
<PAGE>   692
 
      default on a mortgage), and except to the extent that Strategic
      Transactions the Fund may engage in are considered to be commodities or
      commodities contracts.
 
  The Fund may not change any of these investment restrictions nor any other
fundamental policy as they apply to the Fund without the approval of the lesser
of (i) more than 50% of the Fund's outstanding shares or (ii) 67% of the Fund's
shares present at a meeting at which the holders of more than 50% of the
outstanding shares are present in person or by proxy. As long as the percentage
restrictions described above are satisfied at the time of the investment or
borrowing, the Fund will be considered to have abided by those restrictions even
if, at a later time, a change in values or net assets causes an increase or
decrease in percentage beyond that allowed.
 
  The Fund generally will not engage in the trading of securities for the
purpose of realizing short-term profits, but it will adjust its portfolio as
deemed advisable in view of prevailing or anticipated market conditions to
accomplish the Fund's investment objectives. For example, the Fund may sell
portfolio securities in anticipation of a movement in interest rates. Frequency
of portfolio turnover will not be a limiting factor if the Fund considers it
advantageous to purchase or sell securities. Portfolio turnover is calculated by
dividing the lesser of purchases or sales of portfolio securities by the monthly
average value of the securities in the portfolio during the year. Securities,
including options, whose maturity or expiration date at the time of acquisition
were one year or less are excluded from such calculation. The Fund anticipates
that its annual portfolio turnover rate will normally be less than 200%.
 
                      ADDITIONAL INVESTMENT CONSIDERATIONS
 
MUNICIPAL SECURITIES
 
  Municipal securities include long-term obligations, which are often called
municipal bonds, as well as shorter term municipal notes, municipal leases, and
tax exempt commercial paper. Under normal market conditions, longer term
municipal securities generally provide a higher yield than shorter term
municipal securities, and therefore the Fund generally expects to be invested
primarily in longer term municipal securities. The Fund will, however, invest in
shorter term municipal securities when yields are greater than yields available
on longer term municipal securities, for temporary defensive purposes and when
redemption requests are expected. The two principal classifications of municipal
bonds are "general obligation" and "revenue" or "special obligation" bonds,
which include "industrial revenue bonds." General obligation bonds are secured
by the issuer's pledge of its faith, credit, and taxing power for the payment of
principal and interest. Revenue or special obligation bonds are payable only
from the revenues derived from a particular facility or class of facilities or,
in some cases, from the proceeds of a special excise tax or other specific
revenue source such as from the user of the facility being financed.
 
  Also included within the general category of municipal securities are
participations in lease obligations or installment purchase contract obligations
(hereinafter collectively called "lease obligations") of State and local
governments or authorities of entities used to finance the acquisition of
equipment and facilities. Lease obligations generally do not constitute general
obligations of the municipality for which the municipality's taxing power is
pledged. A lease obligation is ordinarily backed by the municipality's covenant
to budget for, appropriate and make the payments due under the lease obligation.
However, certain lease obligations contain "non-appropriation" clauses which
provide that the municipality has no obligation to make lease or installment
purchase payments in future years unless money is appropriated for such purpose
on a yearly basis. A risk exists that the municipality will not, or will be
unable to, appropriate money in the future in the event of political changes,
changes in the economic viability of the project, general economic changes or
for other reasons. In addition to the "non-appropriation" risk, these securities
represent a relatively new type of financing that has not yet developed the
depth of marketability associated with more conventional bonds. Although
"non-appropriation" lease obligations are often secured by an assignment of the
lessee's interest in the leased property, management and/or disposition of the
property in the event of foreclosure could be costly, time consuming and result
in unsatisfactory recoupment of the Fund's original investment. Additionally,
use of the leased property may be limited by State or local law to a specified
use thereby further limiting ability to rent. There is no limitation on the
percentage of the Fund's assets that may be invested in "non-appropriation"
 
                                       B-4
<PAGE>   693
 
   
lease obligations. In evaluating such lease obligations, the Adviser will
consider such factors as it deems appropriate, which factors may include (a)
whether the lease can be cancelled, (b) the ability of the lease obligee to
direct the sale of the underlying assets, (c) the general creditworthiness of
the lease obligor, (d) the likelihood that the municipality will discontinue
appropriating funding for the leased property in the event such property is no
longer considered essential by the municipality, (e) the legal recourse of the
lease obligee in the event of such a failure to appropriate funding and (f) any
limitations which are imposed on the lease obligor's ability to utilize
substitute property or services than those covered by the lease obligation.
"Non-Substitution" clauses in municipal lease transactions have recently been
held unenforceable in Florida as violative of public policy. The Fund will
invest in lease obligations which contain non-appropriation clauses only if such
obligations are rated investment grade, at the time of investment.
    
 
  Also included in the term municipal securities are participation certificates
issued by state and local governments or authorities to finance the acquisition
of equipment and facilities. They may represent participations in a lease, an
installment purchase contract, or a conditional sales contract.
 
  The Fund may purchase floating and variable rate demand notes, which are
municipal securities normally having a stated maturity in excess of one year,
but which permit the holder to demand payment of principal at any time, or at
specified intervals. The issuer of such notes normally has a corresponding
right, after a given period, to prepay at its discretion upon notice to the
noteholders the outstanding principal amount of the notes plus accrued interest.
The interest rate on a floating rate demand note is based on a known lending
rate, such as a bank's prime rate, and is adjusted automatically each time such
rate is adjusted. The interest rate on a variable rate demand note is adjusted
automatically at specified intervals.
 
  The Fund also may invest up to 20% of its total assets in variable rate
derivative municipal securities such as inverse floaters whose rates vary
inversely with changes in market rates of interest. When market rates of
interest decrease, the change in value of such securities will have a positive
effect on the net asset value of the Fund and when market rates of interest
increase, the change in value of such securities will have a negative effect on
the net asset value of the Fund. Inverse floaters may pay a rate of interest
determined by applying a multiple to the variable rate. The extent of increases
and decreases in the value of inverse floaters in response to changes in market
rates of interest generally will be larger than comparable changes in the value
of an equal principal amount of a fixed rate municipal security having similar
credit quality, redemption provisions and maturity.
 
  The Fund may also acquire custodial receipts or certificates underwritten by
securities dealers or banks that evidence ownership of future interest payments,
principal payments or both on certain municipal securities. The underwriter of
these certificates or receipts typically purchases municipal securities and
deposits the securities in an irrevocable trust or custodial account with a
custodian bank, which then issues receipts or certificates that evidence
ownership of the periodic unmatured coupon payments and the final principal
payment on the obligations. Although under the terms of a custodial receipt, the
Fund typically would be authorized to assert its rights directly against the
issuer of the underlying obligation, the Fund could be required to assert
through the custodian bank those rights as may exist against the underlying
issuer. Thus, in the event the underlying issuer fails to pay principal or
interest when due, the Fund may be subject to delays, expenses and risks that
are greater than those that would have been involved if the Fund had purchased a
direct obligation of the issuer. In addition, in the event that the trust or
custodial account in which the underlying security has been deposited is
determined to be an association taxable as a corporation, instead of a
non-taxable entity, the yield on the underlying security would be reduced in
recognition of any taxes paid.
 
  The "issuer" of municipal securities generally is deemed to be the
governmental agency, authority, instrumentality or other political subdivision,
or the non-governmental user of a revenue bond-financed facility, the assets and
revenues of which will be used to meet the payment obligations, or the guarantee
of such payment obligations, of the municipal securities.
 
  Although the municipal securities in which the Fund may invest will be insured
as to timely payment of principal and interest, municipal securities, like other
debt obligations, are subject to the risk of non-payment. The ability of issuers
of municipal securities to make timely payments of interest and principal may be
adversely impacted in general economic downturns and as relative governmental
cost burdens are allocated and reallocated among federal, state and local
governmental units. Such non-payment would result in a
 
                                       B-5
<PAGE>   694
 
reduction of income to the Fund, and could result in a reduction in the value of
the municipal security experiencing non-payment and a potential decrease in the
net asset value of the Fund. Issuers of municipal securities might seek
protection under the bankruptcy laws. In the event of bankruptcy of such an
issuer, the Fund could experience delays and limitations with respect to the
collection of principal and interest on such municipal securities and the Fund
may not, in all circumstances, be able to collect all principal and interest to
which it is entitled. To enforce its rights in the event of a default in the
payment of interest or repayment of principal, or both, the Fund may take
possession of and manage the assets securing the issuer's obligations on such
securities, which may increase the Fund's operating expenses and adversely
affect the net asset value of the Fund. Any income derived from the Fund's
ownership or operation of such assets may not be tax-exempt. In addition, the
Fund's intention to qualify as a "regulated investment company" under the
Internal Revenue Code of 1986, as amended (the "Code"), may limit the extent to
which the Fund may exercise its rights by taking possession of such assets,
because as a regulated investment company the Fund is subject to certain
limitations on its investments and on the nature of its income. Further, in
connection with the working out or restructuring of a defaulted security, the
Fund may acquire additional securities of the issuer, the acquisition of which
may be deemed to be a loan of money or property. Such additional securities
should be considered speculative with respect to the capacity to pay interest or
repay principal in accordance with their terms.
 
  The Fund may invest up to 15% of its total assets in illiquid securities,
securities the disposition of which is subject to substantial legal or
contractual restrictions on resale and securities that are not readily
marketable. The sale of restricted and illiquid securities often requires more
time and results in higher brokerage charges or dealer discounts and other
selling expenses than does the sale of securities eligible for trading on
national securities exchanges or in the over-the-counter markets. Restricted
securities may sell at a price lower than similar securities that are not
subject to restrictions on resale. Restricted securities salable among qualified
institutional buyers without restriction pursuant to Rule 144A under the
Securities Act of 1933, as amended, that are determined to be liquid by the
Adviser under guidelines adopted by the Board of Trustees of the Trust (under
which guidelines the Adviser will consider factors such as trading activities
and the availability of price quotations), will not be treated as restricted
securities by the Fund pursuant to such rules. The Fund may, from time to time,
adopt a more restrictive limitation with respect to investment in illiquid and
restricted securities in order to comply with the most restrictive state
securities law, currently 10%. This policy does not include restricted
securities eligible for resale pursuant to Rule 144A under the Securities Act of
1933, as amended, which the Board of Trustees or the Fund's investment adviser
has determined under Board-approved guidelines to be liquid. The Fund's policy
with respect to investment in illiquid and restricted securities is not a
fundamental policy and may be changed by the Board of Trustees, in consultation
with the Adviser, without obtaining shareholder approval.
 
INSURANCE
 
  As described in the Prospectus, the Fund generally will invest substantially
all of its asset in municipal securities which are either pre-insured under a
policy obtained for such securities prior to the purchase of such securities or
will be insured under policies obtained by the Fund to cover otherwise uninsured
securities.
 
  ORIGINAL ISSUE INSURANCE. Original Issue Insurance is purchased with respect
to a particular issue of municipal securities by the issuer thereof or a third
party in conjunction with the original issuance of such municipal securities.
Under such insurance, the insurer unconditionally guarantees to the holder of
the insured municipal security the timely payment of principal and interest on
such obligation when and as such payments shall become due but shall not be paid
by the issuer; except that in the event of any acceleration of the due date of
the principal by reason of mandatory or optional redemption (other than
acceleration by reason of a mandatory sinking fund payment), default or
otherwise, the payments insured may be made in such amounts and at such times as
payments of principal would have been due had there not been such acceleration.
The insurer is responsible for such payments less any amounts received by the
holder from any trustee for the municipal security issuers or from any other
source. Original Issue Insurance generally does not insure payment on an
accelerated basis, the payment of any redemption premium (except with respect to
certain premium payments in the case of certain small issue industrial
development and pollution control municipal securities), the value of the shares
of the Fund or the market value of municipal securities, or payments of any
tender purchase price upon the tender of the municipal securities. Original
Issue Insurance also does not
 
                                       B-6
<PAGE>   695
 
insure against nonpayment of principal of or interest on municipal securities
resulting from the insolvency, negligence or any other act or omission of the
trustee or other paying agent for such obligations.
 
  In the event that interest on or principal of a municipal security covered by
insurance is due for payment but is unpaid by reason of nonpayment by the issuer
thereof, the applicable insurer will make payments to its fiscal agent (the
"Fiscal Agent") equal to such unpaid amounts of principal and interest not later
than one business day after the insurer has been notified that such nonpayment
has occurred (but not earlier than the date of such payment is due). The Fiscal
Agent will disburse to the Fund the amount of principal and interest which is
then due for payment but is unpaid upon receipt by the Fiscal Agent of (i)
evidence of the Fund's right to receive payment of such principal and interest
and (ii) evidence, including any appropriate instrument of assignment, that all
of the rights of payment of such principal or interest then due for payment
shall thereupon vest in the insurer. Upon payment by the insurer of any
principal or interest payments with respect to any municipal securities, the
insurer shall succeed to the rights of the Fund with respect to such payment.
 
  Original Issue Insurance remains in effect as long as the municipal securities
covered thereby remain outstanding and the insurer remains in business,
regardless of whether the Fund ultimately disposes of such municipal securities.
Consequently, Original Issue Insurance may be considered to represent an element
of market value with respect to the municipal securities so insured, but the
exact effect, if any, of this insurance on such market value cannot be
estimated.
 
  SECONDARY MARKET INSURANCE.  Subsequent to the time of original issuance of a
municipal security, the Fund or a third party may, upon the payment of a single
premium, purchase insurance on such municipal security. Secondary Market
Insurance generally provides the same type of coverage as is provided by
Original Issue Insurance and, as is the case with Original Issue Insurance,
Secondary Market Insurance remains in effect as long as the municipal security
covered thereby remains outstanding and the insurer remains in business,
regardless of whether the Fund ultimately disposes of such municipal security.
All premiums respecting municipal securities covered by Original Issue Insurance
or Secondary Market Insurance are paid in advance by the issuer or other party
obtaining the insurance.
 
  One of the purposes of acquiring Secondary Market Insurance with respect to a
particular municipal security would be to enable the Fund to enhance the value
of such municipal security. The Fund, for example, might seek to purchase a
particular municipal security and obtain Secondary Market Insurance with respect
thereto if, in the opinion of the Adviser, the market value of such municipal
security, as insured, would exceed the current value of the municipal security
without insurance plus the cost of the Secondary Market Insurance. Similarly, if
the Fund owns but wishes to sell a municipal security that is then covered by
Portfolio Insurance, the Fund might seek to obtain Secondary Market Insurance
with respect thereto if, in the opinion of the Adviser, the net proceeds of a
sale by the Fund of such obligation, as insured, would exceed the current value
of such obligation plus the cost of the Secondary Market Insurance.
 
  PORTFOLIO INSURANCE.  The Portfolio Insurance policies obtained by the Fund
would insure the payment of principal and interest on specified eligible
municipal securities purchased by the Fund. Except as described below, Portfolio
Insurance generally provides the same type of coverage as is provided by
Original Issue Insurance or Secondary Market Insurance. Municipal securities
insured under one Portfolio Insurance policy generally would not be insured
under any other policy purchased by the Fund. A municipal security is eligible
for coverage under a policy if it meets certain requirements of the insurer.
Portfolio Insurance is intended to reduce financial risk, but the cost thereof
and compliance with investment restrictions imposed under the policy will reduce
the yield to shareholders of the Fund. If a municipal security already is
covered by Original Issue Insurance of Secondary Market Insurance, the Fund is
not required to additionally insure any such municipal security under any policy
of Portfolio Insurance that the Fund may purchase.
 
  Portfolio Insurance policies are effective only as to municipal securities
owned and held by the Fund, and do not cover municipal securities for which the
contract for purchase fails. A "when-issued" municipal security will be covered
under a Portfolio Insurance policy upon the settlement date of the issue of such
"when-issued" municipal security.
 
                                       B-7
<PAGE>   696
 
  In determining whether to insure municipal securities held by the Fund, an
insurer will apply its own standards, which correspond generally to the
standards it has established for determining the insurability of new issues of
municipal securities. See "Original Issue Insurance" above.
 
  Each Portfolio Insurance policy will be non-cancellable and will remain in
effect so long as the Fund is in existence, the municipal securities covered by
the policy continue to be held by the Fund, and the Fund pays the premiums for
the policy. Each insurer generally will reserve the right at any time upon 90
days written notice to the Fund to refuse to insure any additional securities
purchased by the Fund after the effective date of such notice. The Board of
Trustees of the Fund generally will reserve the right to terminate each policy
upon seven days written notice to an insurer if it determines that the cost of
such policy is not reasonable in relation to the value of the insurance to the
Fund.
 
  Each Portfolio Insurance policy shall terminate as to any municipal security
that has been redeemed from or sold by the Fund on the date of such redemption
or the settlement date of such sale, and an insurer shall not have any liability
thereafter under a policy as to any such municipal security, except that if the
date of such redemption or the settlement date of such sale occurs after a
record date and before the related payment date with respect to any such
municipal security, the policy will terminate as to such municipal security on
the business day immediately following such payment date. Each policy will
terminate as to all municipal securities covered thereby on the date on which
the last of the covered municipal securities mature, are redeemed or are sold by
the Fund.
 
  One or more policies of Portfolio Insurance may provide the Fund, pursuant to
an irrevocable commitment of the insurer, with the option to exercise the right
to obtain permanent insurance ("Permanent Insurance") with respect to a
municipal security that is to be sold by the Fund. The Fund would exercise the
right to obtain Permanent Insurance upon payment of a single, predetermined
insurance premium payable from the proceeds of the sale of such municipal
security. It is expected that the Fund will exercise the right to obtain
Permanent Insurance for a municipal security only if, in the opinion of the
Adviser, upon such exercise the net proceeds from the sale by the Fund of such
obligation, as insured, would exceed the proceeds from the sale of such
obligation without insurance. The Permanent Insurance premium with respect to
each such obligation is determined based upon the insurability of each such
obligation as of the date of purchase by the Fund and will not be increased or
decreased for any change in the creditworthiness of such obligation unless such
obligation is in default as to payment of principal or interest, or both. In
such event, the Permanent Insurance premium shall be subject to an increase
predetermined at the date of purchase by the Fund.
 
  Because each Portfolio Insurance policy will terminate as to municipal
securities sold by the Fund on the date of sale, in which event the insurer will
be liable only for those payments of principal and interest that are then due
and owing (unless Permanent Insurance is obtained by the Fund), the provision
for this insurance will not enhance the marketability of securities held by the
Fund, whether or not the securities are in default or in significant risk of
default. On the other hand, since Original Issue Insurance and Secondary Market
Insurance will remain in effect as long as municipal securities covered thereby
are outstanding, such insurance may enhance the marketability of such securities
even when such securities are in default or in significant risk of default, but
the exact effect, if any, on the marketability cannot be estimated. Accordingly,
the Fund may determine to retain or, alternatively, to sell municipal securities
covered by Original Issue Insurance or Secondary Market Insurance that are in
default or in significant risk of default.
 
  It is anticipated that certain of the municipal securities to be purchased by
the Fund will be insured under policies obtained by persons other than the Fund.
In instances in which the Fund purchases municipal securities insured under
policies obtained by persons other than the Fund, the Fund does not pay the
premiums for such policies; rather the cost of such policies may be reflected in
a higher purchase price for such municipal securities. Accordingly, the yield on
such municipal securities may be lower than that on similar uninsured municipal
securities. Premiums for a Portfolio Insurance Policy generally are paid by the
Fund monthly, and are adjusted for purchases and sales of municipal securities
covered by the policy during the month. The yield on the Fund's portfolio is
reduced to the extent of the insurance premiums paid by the Fund which, in turn,
will depend upon the characteristics of the covered municipal securities held by
the Fund. In the event the Fund were to purchase Secondary Market Insurance with
respect to any municipal
 
                                       B-8
<PAGE>   697
 
securities then covered by a Portfolio Insurance policy, the coverage and the
obligation of the Fund to pay monthly premiums under such policy would cease
with such purchase.
 
  There can be no assurance that insurance of the kind described above will
continue to be available to the Fund. In the event that such insurance is no
longer available or that the cost of such insurance outweighs the benefits to
the Fund in the view of the Board of Trustees, the Board will consider whether
to modify the investment policies of the Fund, which may require the approval of
shareholders. In the event the claims-paying ability rating of an insurer of
municipal securities in the Fund's portfolio were to be lowered from AAA by S&P,
Aaa by Moody's or an equivalent rating by another NRSRO, or if the Adviser
anticipates such a lowering or otherwise does not believe an insurer's
claims-paying ability merits its existing triple-A rating, the Fund could seek
to obtain additional insurance from an insurer whose claims-paying ability is
rated AAA by S&P, Aaa by Moody's or an equivalent rating by another NRSRO, or if
the Adviser determines that the cost of obtaining such additional insurance
outweigh the benefits, the Fund may elect not to obtain additional insurance. In
making such determination, the Adviser will consider the cost of the additional
insurance, the new claims-paying ability rating and financial condition of the
existing insurer and the creditworthiness of the issuer or guarantor of the
underlying municipal securities. The Adviser also may determine not to purchase
additional insurance in such circumstances if it believes that the insurer is
taking steps which will cause its triple-A claims paying ability rating to be
restored promptly.
 
  Although the Adviser periodically reviews the financial condition of each
insurer, there can be no assurance that the insurers will be able to honour
their obligations under all circumstances. In that regard, it should be noted
that the claims-paying abilities and debt ratings of several large insurers (at
least one of which insured municipal securities) recently have been lowered by
one or more of the nationally recognized securities rating agencies and that
many insurers currently are experiencing adverse results in their investment
portfolios. In addition, certain insurers' operations recently have been assumed
by their state regulatory agencies. The Fund cannot predict the consequences of
a state takeover of an insurer's obligations and, in particular, whether such an
insurer (or its state regulatory agency) could or would honour all of the
insurer's contractual obligations including any outstanding insurance contracts
insuring the timely payment of principal and interest on municipal securities.
The Fund cannot predict the impact which such events might have on the market
values of such municipal security. In the event of a default by an insurer on
its obligations with respect to any municipal securities in the Fund's
portfolio, the Fund would look to the issuer and/or guarantor of the relevant
municipal securities for payments of principal and interest and such issuer
and/or guarantor may not be rated AAA by S&P, Aaa by Moody's or an equivalent
rating by another NRSRO. Accordingly, the Fund could be exposed to greater risk
of non-payment in such circumstances which could adversely affect the Fund's net
asset value and the market price per Common Share. Alternatively, the Fund could
elect to dispose of such municipal securities; however, the market prices for
such municipal securities may be lower than the Fund's purchase price for them
and the Fund could sustain a capital loss as a result.
 
  Although the insurance on municipal securities reduces financial or credit
risk in respect of the insured obligations (i.e., the possibility that owners of
the insured municipal securities will not receive timely scheduled payments of
principal or interest), insured municipal securities remain subject to market
risk (i.e., fluctuations in market value as a result of changes in prevailing
interest rates). Accordingly, insurance on municipal securities does not insure
the market value of the Fund's assets or the net asset value or the market price
for the Common Shares.
 
SPECIAL CONSIDERATIONS REGARDING FLORIDA MUNICIPAL SECURITIES
 
  GENERAL.  As described in the Prospectus, except during temporary periods, the
Fund will invest substantially all of its assets in Florida municipal
securities. The Fund is therefore susceptible to political, economic, regulatory
or other factors affecting issuers of Florida municipal securities. In addition,
the specific Florida municipal securities in which the Fund will invest are
expected to change from time to time. The following information constitutes only
a brief summary of some of the complex factors which may have an impact on the
financial situation of issuers of Florida municipal securities and does not
purport to be a complete or exhaustive description of all adverse conditions to
which issuers of Florida municipal securities may be subject and is not
applicable to "conduit" obligations, such as industrial development revenue
bonds, with respect to which the public issuer itself has no financial
responsibility. Such information is derived from certain official
 
                                       B-9
<PAGE>   698
 
statements of the State of Florida published in connection with the issuance of
specific State of Florida securities, as well as from other publicly available
documents. Such information has not been independently verified by the Fund and
may not apply to all Florida municipal securities acquired by the Fund. The Fund
assumes no responsibility for the completeness or accuracy of such information.
 
  Additionally, many factors, including national, economic, social and
environmental policies and conditions, which are not within the control of such
issuers, could have an adverse impact on the financial condition of such
issuers. The Fund cannot predict whether or to what extent such factors or other
factors may affect the issuers of Florida municipal securities, the market value
or marketability of such securities or the ability of the respective issuers of
such securities acquired by the Fund to pay interest on or principal of such
securities. The creditworthiness of obligations issued by local Florida issuers
may be unrelated to the creditworthiness of obligations issued by the State of
Florida, and there is no responsibility on the part of the State of Florida to
make payments on such local obligations. There may be specific factors that are
applicable in connection with investment in the obligations of particular
issuers located within Florida, and it is possible the Fund will invest in
obligations of particular issuers as to which such specific factors are
applicable. However, the information set forth below is intended only as a
general summary and not as a discussion of any specific factors that may affect
any particular issuer of Florida municipal securities.
 
   
  Florida state and local government obligations may be adversely affected by
political and economic conditions and developments within the State of Florida
and the nation as a whole. Florida's economic outlook is generally projected to
reflect the national economic outlook, and is expected to experience steady if
unspectacular growth over the next couple of years. The Florida constitution and
statutes require a balanced budget, which may affect the ability of the State of
Florida to issue and/or repay its obligations. In addition, various limitations
on the State of Florida, its governmental agencies and its local governments,
including school and special districts and authorities, may inhibit the ability
of these issuers to repay existing indebtedness and issue additional
indebtedness. The ability of such issuers to repay revenue bonds will also
depend on the success of the capital projects to which they relate. The ability
of such issuers to repay general obligation bonds will also depend on the
success of such issuer maintaining its ad valorem tax base.
    
 
  INVESTMENT PRACTICES AND POLICIES OF ISSUERS OF FLORIDA MUNICIPAL
ISSUERS. Florida law does provide certain restrictions on the investment of
funds for the State of Florida and its local governments; however, with respect
to all municipalities and its charter counties, such restrictions may be limited
by the constitutional home rule powers of such entities. Although the Florida
municipal securities which may be purchased by the Fund will be insured, only
those securities which are insured by Original Issuance Insurance will contain
restrictions on investments imposed by the issuer of such insurance. Because
statutory restrictions on investments and investment policies with respect to
the investment of funds is limited by constitutional home rule powers, there can
be no assurance as to whether any issuer will suffer losses as a result of
investments or the magnitude or any such losses.
 
   
  POPULATION, INCOME AND EMPLOYMENT.  Florida has experienced a large population
growth. As of April 1, 1995, Florida ranks fourth with an estimated population
of 14.1 million. Since the beginning of the eighties, Florida has surpassed
Ohio, Illinois and Pennsylvania in total population, and in the ten years ended
in 1995 an average 227,000 new residents make Florida their home each year. The
personal income of residents of Florida has been growing strongly the last
several years and generally has historically outperformed both the nation as a
whole and the southeast in particular. The State's economy since the early
seventies has diversified in such a way as to provide a greater insulation from
national economic downturns. The structure of income of residents of Florida
differs from that of the nation and the southeast in that, due to a
proportionately greater retirement age population, property income (dividends,
interest and rent) and transfer payments (Social Security and pension benefits,
among other sources of income) are an important source of income.
    
 
   
  Real personal income in Florida is estimated to increase at 4.2% and 4.4% for
1996-97 and 1997-98 respectively while real personal income per capita is
projected to grow 2.3% in 1996-97 and 2.6% in 1997-98.
    
 
   
  Florida's economic dependence on the cyclical construction and construction
related manufacturing sectors has declined. The service sector is Florida's
largest employer. Presently, the State's service sector employment constitutes
nearly 87% of the total non-farm employment. While structurally the southeast
and the nation are
    
 
                                      B-10
<PAGE>   699
 
endowed with a greater proportion of manufacturing jobs, which tend to pay
higher wages, service jobs are less sensitive to business cycle swings.
 
   
  Historically, Florida's unemployment rate has generally tracked below that of
the nation; however, in recent years, as the State's economic growth has slowed
from its previous highs, the unemployment rate has tracked above the national
average. The average rate of unemployment for Florida since 1986 is 6.2% while
the national average during the same time period is also 6.2%. Florida's
unemployment rate is forecasted at 5.3% for both fiscal years 1996-97 and
1997-98.
    
 
   
  TOURISM INDUSTRY.  Tourism is one of Florida's most important industries.
Approximately 40.7 million people visited the State in 1995. By the end of
fiscal year 1996-97, 42.6 million domestic and international tourists are
expected to have visited the State. In 1997-98 tourist arrivals should
approximate 43.9 million.
    
 
   
  STATE FINANCIAL OPERATIONS.  Financial operations of the State covering all
receipts and expenditures are maintained through the use of four funds--the
General Revenue Fund, Trust Funds, the Working Capital Fund, and the Budget
Stabilization Fund. In fiscal year 1995-96, the State derived an estimated 66%
of its total direct revenues to these funds from state taxes. Federal funds and
other special revenues accounted for the remaining revenues. Major sources of
tax revenues to the General Revenue Fund are the sales and use tax, corporate
income tax, intangible personal property tax, and beverage tax, which amounted
to 69%, 7%, 4% and 4%, respectively, of the total General Revenue funds
available. State expenditures are categorized for budget and appropriation
purposes by type of fund and spending unit, which are further subdivided by line
item. In fiscal year 1995-96, appropriations from the General Revenue Fund for
education, health and welfare, and public safety amounted to approximately 51%,
31%, and 14%, respectively, of total General Revenues.
    
 
  The sales and use tax is the greatest single source of tax receipts in
Florida. The sales tax is 6% of the sales price of tangible personal property
sold at retail in the State. The use tax is at 6% of the cost price of tangible
personal property when the same is not sold but is used, or stored for use, in
the State. Slightly less than 10% of the sales tax is designated for local
governments and is distributed to the respective counties in which collected for
use by the county and the municipalities therein. In addition to this
distribution, local governments may (by referendum) assess certain discretionary
sales surtaxes within their county, for certain purposes, restricted as to
amount. The proceeds of these surtaxes are required to be applied to the
purposes for which such surtax is assessed.
 
   
  For the State fiscal year which ended June 30, 1996, receipts from the sales
and use tax were $11,461 million, an increase of 7.4% from fiscal year 1994-95.
    
 
   
  The second largest source of State tax receipts, including those distributed
to local governments, is the tax on motor fuels. Preliminary data show
collections from this source in the State fiscal year ending June 30, 1996 were
$1,923.0 million. However, these revenues are almost entirely trust funds
dedicated for specific purposes and are not included in the State General
Revenue Fund. Alcoholic beverage tax and license revenues totalled $441.5
million in the State fiscal year ended June 30, 1996. The receipts of corporate
income tax for the State fiscal year ended June 30, 1996 were $1,162.7 million,
an increase of 9.3% over the prior fiscal year. In November 1986, the voters of
the State approved a constitutional amendment to allow the State to operate a
lottery, the proceeds of which are required to be applied as follows: 50% to be
returned to the public as prizes, at least 38% to be deposited in the
Educational Enhancement Trust (for public education), and no more than 12% to be
spent on the administrative cost of operating the lottery. State fiscal year
1995-96 produced ticket sales of $2.07 billion of which education received
approximately $788.1 million.
    
 
  The State Constitution does not permit a personal income tax. An amendment to
the State Constitution would be required to impose a personal income tax in the
State.
 
   
  Estimated fiscal year 1995-96 General Revenue plus Working Capital and Budget
Stabilization funds available total $15,419.3 million, 4.0% increase over
1994-95.
    
 
   
  In fiscal year 1996-97 estimated General Revenue plus Working Capital and
Budget Stabilization funds available total $16,601.7 million, a 7.7% increase
over 1995-96. The $15,566.9 million in Estimated Revenues represent a 6.2%
increase over the analogous figure in 1995-96.

  According to the Division of Bond Finance of the Department of General
Services of the State, as of March 12, 1997, the State maintains a high bond
rating from Moody's Investors Service, Inc. (Aa2), Standard & Poor's Corporation
(AA) and Fitch Investors Service (AA) on the majority of its full faith and
credit bonds. Standard & Poor's Corporation has recently upgraded its rating to
AA+. Outstanding full faith and credit bonds at February 19, 1997 totalled
approximately $8.207 billion.
    
 
  LOCAL GOVERNMENT REVENUE SOURCES. County and municipal governments in Florida
depend primarily upon ad valorem property taxes, and sales, motor fuels and
other local excise taxes and miscellaneous revenue sources, including revenues
from utilities services. Florida school districts derive substantially all of
their revenues from local property taxes. The overall levels of revenues from
these sources is in part dependent upon the local, state and national economy.
Local government obligations held by the Fund may constitute general obligations
or may be special obligations payable solely from one or more specified revenue
sources. The ability of the local governments to repay their obligations on a
timely basis will be dependent upon the continued strength of the revenues
pledged and of the overall fiscal status of the local government.
 
   
  STATE CONSTITUTIONAL AMENDMENT LIMITING STATE REVENUES. An amendment to the
Constitution of the State of Florida was approved by the voters of the State of
Florida at the November 1994 general election. This amendment limits the amount
of taxes, fees, licenses and charges imposed by the State Legislature and
collected during any fiscal year to the amount of revenues allowed for the prior
fiscal year, plus an adjustment for growth. Growth is defined as the amount
equal to the average annual rate of growth in Florida personal income over the
most recent twenty quarters times the state revenues allowed for the prior
fiscal year. The revenues allowed for any fiscal year could be increased by a
two-thirds vote of the Legislature. The limit was effective in the fiscal year
1995-1996. Excess revenues generated will initially be deposited in the budget
stabilization fund until it is fully funded; any additional excess revenues will
then be refunded to taxpayers. This amendment could limit the amount of actual
revenues from which the State of Florida could appropriate funds, including
funds appropriated to local governments. It is unclear at this point what
effect, if any, this amendment would have on local government debt obligations
payable from state revenues which may be subject to this amendment, such as
state revenue sharing moneys or other state revenues distributed to local
governments. Certain State of Florida debt obligations, which are not by their
terms subject to appropriation, should not be affected, depending upon the
language of the legislation authorizing the issuance of such obligations.
    
 
  OTHER FACTORS. Florida will continue to face enormous spending pressures well
into the future. The large number of elderly residents will continue to demand
health services, an area where cost escalation is significant, and the constant
influx of people to Florida will continue to place sizable pressure on the State
for infrastructure needs.
 
  The value of Florida municipal instruments may also be affected by general
conditions in the money markets or the municipal bond markets, the levels of
federal income tax rates, the supply of tax-exempt bonds, the credit quality and
rating of the issues and perceptions with respect to the level of interest
rates.
 
  There can be no assurance that there will not be a decline in economic
conditions or that particular Florida municipal securities in the portfolio of
the Fund will not be adversely affected by any such changes.
 
STRATEGIC TRANSACTIONS
 
  The Fund may, but is not required to, utilize various other investment
strategies as described below to hedge various market risks (such as interest
rates and broad or specific market movements) or to manage the effective
maturity or duration of the Fund's fixed-income securities. Such strategies are
generally accepted by modern portfolio managers and are regularly utilized by
many mutual funds and other institutional investors. Techniques and instruments
may change over time as new instruments and strategies are developed or
regulatory changes occur.
 
  In the course of pursuing these investment strategies, the Fund may purchase
and sell derivative instruments such as exchange-listed and over-the-counter put
and call options on securities, fixed-income indices and other financial
instruments, purchase and sell financial futures contracts and options thereon,
enter into various interest rate transactions such as swaps, caps, floors or
collars (collectively, all the above are called
 
                                      B-12
<PAGE>   701
 
"Strategic Transactions"). Strategic Transactions may be used to attempt to
protect against possible changes in the market value of securities held in or to
be purchased for the Fund's portfolio resulting from securities markets
fluctuations, to protect the Fund's unrealized gains in the value of its
portfolio securities, to facilitate the sale of such securities for investment
purposes, to manage the effective maturity or duration of the Fund's portfolio,
or to establish a position in the derivatives markets as a temporary substitute
for purchasing or selling particular securities.
 
  Any or all of these investment techniques may be used at any time and there is
no particular strategy that dictates the use of one technique rather than
another, as use of any Strategic Transaction is a function of numerous variables
including market conditions. The ability of the Fund to utilize these Strategic
Transactions successfully will depend on the Adviser's ability to predict
pertinent market movements, which cannot be assured. The Fund will comply with
applicable regulatory requirements when implementing these strategies,
techniques and instruments. Strategic Transactions involving financial futures
and options thereon will be purchased, sold or entered into only for bona fide
hedging, risk management or portfolio management purposes and not for
speculative purposes.
 
  Strategic Transactions have risks associated with them including possible
default by the other party to the transaction, illiquidity and, to the extent
the Adviser's view as to certain market movements is incorrect, the risk that
the use of such Strategic Transactions could result in losses greater than if
they had not been used. Use of put and call options may result in losses to the
Fund, force the sale or purchase of portfolio securities at inopportune times or
for prices other than current market values, limit the amount of appreciation
the Fund can realize on its investments or cause the Fund to hold a security it
might otherwise sell. The use of options and futures transactions entails
certain other risks. In particular, the variable degree of correlation between
price movements of futures contracts and price movements in the related
portfolio position of the Fund creates the possibility that losses on the
hedging instrument may be greater than gains in the value of the Fund's
position. In addition, futures and options markets may not be liquid in all
circumstances and certain over-the-counter options may have no markets. As a
result, in certain markets, the Fund might not be able to close out a
transaction without incurring substantial losses, if at all. Although the use of
futures and options transactions for hedging should tend to minimize the risk of
loss due to a decline in the value of the hedged position, at the same time they
tend to limit any potential gain which might result from an increase in value of
such position. Finally, the daily variation margin requirements for futures
contracts would create a greater ongoing potential financial risk than would
purchases of options, where the exposure is limited to the cost of the initial
premium. Losses resulting from the use of Strategic Transactions would reduce
net asset value, and possibly income, and such losses can be greater than if the
Strategic Transactions had not been utilized. Income earned or deemed to be
earned, if any, by the Fund from its Strategic Transactions will generally be
taxable income of the Fund. See "Tax Status" in the Prospectus.
 
  GENERAL CHARACTERISTICS OF OPTIONS. Put options and call options typically
have similar structural characteristics and operational mechanics regardless of
the underlying instrument on which they are purchased or sold. Thus, the
following general discussion relates to each of the particular types of options
discussed in greater detail below. In addition, many Strategic Transactions
involving options require segregation of Fund assets in special accounts, as
described below under "Use of Segregated and Other Special Accounts."
 
  A put option gives the purchaser of the option, upon payment of a premium, the
right to sell, and the writer the obligation to buy, the underlying security,
commodity, index, or other instrument at the exercise price. For instance, the
Fund's purchase of a put option on a security might be designed to protect its
holdings in the underlying instrument (or, in some cases, a similar instrument)
against a substantial decline in the market value by giving the Fund the right
to sell such instrument at the option exercise price. A call option, upon
payment of a premium, gives the purchaser of the option the right to buy, and
the seller the obligation to sell, the underlying instrument at the exercise
price. The Fund's purchase of a call option on a security, financial future,
index, or other instrument might be intended to protect the Fund against an
increase in the price of the underlying instrument that it intends to purchase
in the future by fixing the price at which it may purchase such instrument. An
American style put or call option may be exercised at any time during the option
period while a European style put or call option may be exercised only upon
expiration or during a fixed period prior thereto. The Fund is authorized to
purchase and sell exchange listed options and over-the-counter options ("OTC
options"). Exchange listed options are issued by a regulated intermediary such
as the Options
 
                                      B-13
<PAGE>   702
 
Clearing Corporation ("OCC"), which guarantees the performance of the
obligations of the parties to such options. The discussion below uses the OCC as
a paradigm, but is also applicable to other financial intermediaries.
 
  With certain exceptions, OCC issued and exchange listed options generally
settle by physical delivery of the underlying security or currency, although in
the future cash settlement may become available. Index options and Eurodollar
instruments are cash settled for the net amount, if any, by which the option is
"in-the-money" (i.e., where the value of the underlying instrument exceeds, in
the case of a call option, or is less than, in the case of a put option, the
exercise price of the option) at the time the option is exercised. Frequently,
rather than taking or making delivery of the underlying instrument through the
process of exercising the option, listed options are closed by entering into
offsetting purchase or sale transactions that do not result in ownership of the
new option.
 
  The Fund's ability to close out its position as a purchaser or seller of an
OCC or exchange listed put or call option is dependent, in part, upon the
liquidity of the option market. Among the possible reasons for the absence of a
liquid option 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 including
reaching daily price limits; (iv) interruption of the normal operations of the
OCC or an exchange; (v) inadequacy of the facilities of an exchange or 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 relevant market for that option on that exchange would cease
to exist, although outstanding options on that exchange would generally continue
to be exercisable in accordance with their terms.
 
  The hours of trading for listed options may not coincide with the hours during
which the underlying financial instruments are traded. To the extent that the
option markets close before the markets for the underlying financial
instruments, significant price and rate movements can take place in the
underlying markets that cannot be reflected in the option markets.
 
  OTC options are purchased from or sold to securities dealers, financial
institutions or other parties ("Counterparties") through direct bilateral
agreement with the Counterparty. In contrast to exchange listed options, which
generally have standardized terms and performance mechanics, all the terms of an
OTC option, including such terms as method of settlement, term, exercise price,
premium, guarantees and security, are set by negotiation of the parties. The
Fund will only sell OTC options that are subject to a buy-back provision
permitting the Fund to require the Counterparty to sell the option back to the
Fund at a formula price within seven days. The Fund expects generally to enter
into OTC options that have cash settlement provisions, although it is not
required to do so.
 
  Unless the parties provide for it, there is no central clearing or guaranty
function in an OTC option. As a result, if the Counterparty fails to make or
take delivery of the security, or other instrument underlying an OTC option it
has entered into with the Fund or fails to make a cash settlement payment due in
accordance with the terms of that option, the Fund will lose any premium it paid
for the option as well as any anticipated benefit of the transaction.
Accordingly, the Adviser must assess the creditworthiness of each such
Counterparty or any guarantor or credit enhancement of the Counterparty's credit
to determine the likelihood that the terms of the OTC option will be satisfied.
The Fund will engage in OTC option transactions only with United States
government securities dealers recognized by the Federal Reserve Bank of New York
as "primary dealers", or broker dealers, domestic or foreign banks or other
financial institutions which have received (or the guarantors of the obligation
of which have received) a short-term credit rating of "A-1" from S&P or "P-1"
from Moody's or an equivalent rating from any other NRSRO. The staff of the SEC
currently takes the position that, in general, OTC options on securities other
than U.S. Government securities purchased by the Fund, and portfolio securities
"covering" the amount of the Fund's obligation pursuant to an OTC option sold by
it (the cost of the sell-back plus the in-the-money amount, if any) are
illiquid, and are subject to the Fund's limitation on investing no more than 15%
of its assets in illiquid securities.
 
  If the Fund sells a call option, the premium that it receives may serve as a
partial hedge, to the extent of the option premium, against a decrease in the
value of the underlying securities or instruments in its portfolio or will
increase the Fund's income. The sale of put options can also provide income.
 
                                      B-14
<PAGE>   703
 
  The Fund may purchase and sell call options on securities, including U.S.
Treasury and agency securities, municipal obligations, mortgage-backed
securities and Eurodollar instruments that are traded on U.S. and foreign
securities exchanges and in the over-the-counter markets. All calls sold by the
Fund must be "covered" (i.e., the Fund must own the securities or futures
contract subject to the call) or must meet the asset segregation requirements
described below as long as the call is outstanding. Even though the Fund will
receive the option premium to help protect it against loss, a call sold by the
Fund exposes the Fund during the term of the option to possible loss of
opportunity to realize appreciation in the market price of the underlying
security or instrument and may require the Fund to hold a security or instrument
which it might otherwise have sold. In the event of exercise of a call option
sold by the Fund with respect to securities not owned by the Fund, the Fund may
be required to acquire the underlying security at a disadvantageous price in
order to satisfy its obligation with respect to the call option.
 
  The Fund may purchase and sell put options on securities including U.S.
Treasury and agency securities, mortgage-backed securities, municipal
obligations and Eurodollar instruments (whether or not it holds the above
securities in its portfolio.) The Fund will not sell put options if, as a
result, more than 50% of the Fund's assets would be required to be segregated to
cover its potential obligations under such put options other than those with
respect to futures and options thereon. In selling put options, there is a risk
that the Fund may be required to buy the underlying security at a
disadvantageous price above the market price.
 
  GENERAL CHARACTERISTICS OF FUTURES.  The Fund may enter into financial futures
contracts or purchase or sell put and call options on such futures as a hedge
against anticipated interest rate or fixed-income market changes, for duration
management and for risk management purposes. Futures are generally bought and
sold on the commodities exchanges where they are listed with payment of initial
and variation margin as described below. The purchase of a futures contract
creates a firm obligation by the Fund, as purchaser, to take delivery from the
seller the specific type of financial instrument called for in the contract at a
specific future time for a specified price (or, with respect to index futures
and Eurodollar instruments, the net cash amount). The sale of a futures contract
creates a firm obligation by the Fund, as seller, to deliver to the buyer the
specific type of financial instrument called for in the contract at a specific
future time for a specified price (or, with respect to index futures and
Eurodollar instruments, the net cash amount). Options on futures contracts are
similar to options on securities except that 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 and obligates the seller to deliver such option.
 
  The Fund's use of financial futures and options thereon will in all cases be
consistent with applicable regulatory requirements and in particular the rules
and regulations of the Commodity Futures Trading Commission and will be entered
into only for bona fide hedging, risk management (including duration management)
or other portfolio management purposes. Typically, maintaining a futures
contract or selling an option thereon requires the Fund to deposit with a
financial intermediary as security for its obligations an amount of cash or
other specified assets (initial margin) which initially is typically 1% to 10%
of the face amount of the contract (but may be higher in some circumstances).
Additional cash or assets (variation margin) may be required to be deposited
thereafter on a daily basis as the mark to market value of the contract
fluctuates. The purchase of options on financial futures involves payment of a
premium for the option without any further obligation on the part of the Fund.
If the Fund exercises an option on a futures contract it will be obligated to
post initial margin (and potential subsequent variation margin) for the
resulting futures position just as it would for any position. Futures contracts
and options thereon are generally settled by entering into an offsetting
transaction but there can be no assurance that the position can be offset prior
to settlement at an advantageous price nor that delivery will occur.
 
  The Fund will not enter into a futures contract or related option (except for
closing transactions) for other than bona fide hedging purposes if, immediately
thereafter, the sum of the amount of its initial margin and premiums on open
futures contracts and options thereon would exceed 5% of the Fund's total assets
(taken at current value); however, in the case of an option that is in-the-money
at the time of the purchase, the in-the-money amount may be excluded in
calculating the 5% limitation. Certain state securities laws to which the Fund
may be subject may further restrict the Fund's ability to engage in transactions
in futures contracts and related options. The segregation requirements with
respect to futures contracts and options thereon are described below.
 
                                      B-15
<PAGE>   704
 
  OPTIONS ON SECURITIES INDICES AND OTHER FINANCIAL INDICES.  The Fund also may
purchase and sell call and put options on securities indices and other financial
indices and in so doing can achieve many of the same objectives it would achieve
through the sale or purchase of options on individual securities or other
instruments. Options on securities indices and other financial indices are
similar to options on a security or other instrument except that, rather than
settling by physical delivery of the underlying instrument, they settle by cash
settlement, i.e., an option on an index gives the holder the right to receive,
upon exercise of the option, an amount of cash if the closing level of the index
upon which the option is based exceeds, in the case of a call, or is less than,
in the case of a put, the exercise price of the option (except if, in the case
of an OTC option, physical delivery is specified). This amount of cash is equal
to the excess of the closing price of the index over the exercise price of the
option, which also may be multiplied by a formula value. The seller of the
option is obligated, in return for the premium received, to make delivery of
this amount. The gain or loss on an option on an index depends on price
movements in the instruments making up the market, market segment, industry or
other composite on which the underlying index is based, rather than price
movements in individual securities, as is the case with respect to options on
securities.
 
  COMBINED TRANSACTIONS.  The Fund may enter into multiple transactions,
including multiple options transactions, multiple futures transactions and
multiple interest rate transactions and any combination of futures, options and
interest rate transactions ("component" transactions), instead of a single
Strategic Transaction, as part of a single or combined strategy when, in the
opinion of the Adviser, it is in the best interests of the Fund to do so. A
combined transaction will usually contain elements of risk that are present in
each of its component transactions. Although combined transactions are normally
entered into based on the Adviser's judgment that the combined strategies will
reduce risk or otherwise more effectively achieve the desired portfolio
management goal, it is possible that the combination will instead increase such
risks or hinder achievement of the portfolio management objective.
 
  SWAPS, CAPS, FLOORS AND COLLARS.  Among the Strategic Transactions into which
the Fund may enter are interest rate and index swaps and the purchase or sale of
related caps, floors and collars. The Fund expects to enter into these
transactions primarily to preserve a return or spread on a particular investment
or portion of its portfolio, as a duration management technique or to protect
against any increase in the price of securities the Fund anticipates purchasing
at a later date. The Fund intends to use these transactions as hedges and not as
speculative investments and will not sell interest rate caps or floors where it
does not own securities or other instruments providing the income stream the
Fund may be obligated to pay. Interest rate swaps involve the exchange by the
Fund with another party of their respective commitments to pay or receive
interest, e.g., an exchange of floating rate payments for fixed rate payments
with respect to a notional amount of principal. An index swap is an agreement to
swap cash flows on a notional amount based on changes in the values of the
reference indices. The purchase of a cap entitles the purchaser to receive
payments on a notional principal amount from the party selling such cap to the
extent that a specified index exceeds a predetermined interest rate or amount.
The purchase of a floor entitles the purchaser to receive payments on a notional
principal amount from the party selling such floor to the extent that a
specified index falls below a predetermined interest rate or amount. A collar is
a combination of a cap and a floor that preserves a certain return within a
predetermined range of interest rates or values.
 
  The Fund will usually enter into swaps on a net basis, i.e., the two payment
streams are netted out in a cash settlement on the payment date or dates
specified in the instrument, with the Fund receiving or paying, as the case may
be, only the net amount of the two payments. Inasmuch as these swaps, caps,
floors and collars are entered into for good faith hedging purposes, the Adviser
and the Fund believe such obligations do not constitute senior securities under
the 1940 Act and, accordingly, will not treat them as being subject to its
borrowing restrictions. The Fund will not enter into any swap, cap, floor or
collar transaction unless, at the time of entering into such transaction, the
unsecured long-term debt of the Counterparty, combined with any credit
enhancements, is rated at least "A" by S&P or Moody's or has an equivalent
equity rating from an NRSRO or is determined to be of equivalent credit quality
by the Adviser. If there is a default by the Counterparty, the Fund may have
contractual remedies pursuant to the agreements related to the transaction. The
swap market has grown substantially in recent years with a large number of banks
and investment banking firms acting both as principals and agents utilizing
standardized swap documentation. As a result, the swap
 
                                      B-16
<PAGE>   705
 
market has become relatively liquid. Caps, floors and collars are more recent
innovations for which standardized documentation has not yet been fully
developed and, accordingly, they are less liquid than swaps.
 
   
  USE OF SEGREGATED AND OTHER SPECIAL ACCOUNTS.  Many Strategic Transactions, in
addition to other requirements, require that the Fund segregate liquid
high-grade assets with its custodian to the extent Fund obligations are not
otherwise "covered" through ownership of the underlying security, financial
instrument or currency. In general, either the full amount of any obligation by
the Fund to pay or deliver securities or assets must be covered at all times by
the securities, instruments or currency required to be delivered, or, subject to
any regulatory restrictions, an amount of cash or liquid securities at least
equal to the current amount of the obligation must be segregated with the
custodian. The segregated assets cannot be sold or transferred unless equivalent
assets are substituted in their place or it is no longer necessary to segregate
them. For example, a call option written by the Fund will require the Fund to
hold the securities subject to the call (or securities convertible into the
needed securities without additional consideration) or to segregate liquid
high-grade securities sufficient to purchase and deliver the securities if the
call is exercised. A call option sold by the Fund on an index will require the
Fund to own portfolio securities which correlate with the index or to segregate
liquid assets equal to the excess of the index value over the exercise price on
a current basis. A put option written by the Fund requires the Fund to segregate
liquid securities equal to the exercise price.
    
 
  OTC options entered into by the Fund, including those on securities, financial
instruments or indices and OCC issued and exchange listed index options, will
generally provide for cash settlement. As a result, when the Fund sells these
instruments it will only segregate an amount of assets equal to its accrued net
obligations, as there is no requirement for payment or delivery of amounts in
excess of the net amount. These amounts will equal 100% of the exercise price in
the case of a non cash-settled put, the same as an OCC guaranteed listed option
sold by the Fund, or the in-the-money amount plus any sell-back formula amount
in the case of a cash-settled put or call. In addition, when the Fund sells a
call option on an index at a time when the in-the-money amount exceeds the
exercise price, the Fund will segregate, until the option expires or is closed
out, cash or cash equivalents equal in value to such excess. OCC issued and
exchange listed options sold by the Fund other than those above generally settle
with physical delivery, and the Fund will segregate an amount of assets equal to
the full value of the option. OTC options settling with physical delivery, or
with an election of either physical delivery or cash settlement, will be treated
the same as other options settling with physical delivery.
 
  In the case of a futures contract or an option thereon, the Fund must deposit
initial margin and possible daily variation margin in addition to segregating
assets sufficient to meet its obligation to purchase or provide securities or
currencies, or to pay the amount owed at the expiration of an index-based
futures contract. Such assets may consist of cash, cash equivalents, liquid debt
or equity securities or other acceptable assets.
 
   
  With respect to swaps, the Fund will accrue the net amount of the excess, if
any, of its obligations over its entitlements with respect to each swap on a
daily basis and will segregate an amount of cash or liquid securities having a
value equal to the accrued excess. Caps, floors and collars require segregation
of assets with a value equal to the Fund's net obligation, if any.
    
 
  Strategic Transactions may be covered by other means when consistent with
applicable regulatory policies. The Fund may also enter into offsetting
transactions so that its combined position, coupled with any segregated assets,
equals its net outstanding obligation in related options and Strategic
Transactions. For example, the Fund could purchase a put option if the strike
price of that option is the same or higher than the strike price of a put option
sold by the Fund. Moreover, instead of segregating assets if the Fund held a
futures or forward contract, it could purchase a put option on the same futures
or forward contract with a strike price as high or higher than the price of the
contract held. Other Strategic Transactions may also be offset in combinations.
If the offsetting transaction terminates at the time of or after the primary
transaction no segregation is required, but if it terminates prior to such time,
assets equal to any remaining obligation would need to be segregated.
 
  The Fund's activities involving Strategic Transactions may be limited by the
requirements of the Code for qualification as a regulated investment company.
See "Tax Status" in the Prospectus.

                  DESCRIPTION OF MUNICIPAL SECURITIES RATINGS
 
  STANDARD & POOR'S RATINGS GROUP--A brief description of the applicable
Standard & Poor's Ratings Group (S&P) rating symbols and their meanings (as
published by S&P) follows:
 
     1.  DEBT
 
   
          A S&P corporate or municipal debt rating is a current assessment of
     the creditworthiness of an obligor with respect to a specific obligation.
     This assessment may take into consideration obligors such as guarantors,
     insurers, or lessees.
    
 
          The debt rating is not a recommendation to purchase, sell or hold a
     security, inasmuch as it does not comment as to market price or suitability
     for a particular investor.
 
          The ratings are based on current information furnished by the issuer
     or obtained by S&P from other sources it considers reliable. S&P does not
     perform any 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 based on other circumstances.
 
        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;
 
        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.
 
<TABLE>
    <S>         <C>
    AAA         Debt rated 'AAA' has the highest rating assigned by S&P.
                Capacity to pay interest and repay principal is extremely
                strong.
 
    AA          Debt rated 'AA' has a very strong capacity to pay interest
                and repay principal and differs from the higher rated issues
                only in small degree.
 
    A           Debt rated 'A' has a strong capacity to pay interest and
                repay principal although it is somewhat more susceptible to
                the adverse effects of changes in circumstances and economic
                conditions than debt in higher rated categories.
 
    BBB         Debt rated 'BBB' is regarded as having an adequate capacity
                to pay interest and repay principal. Whereas it normally
                exhibits adequate protection parameters, adverse economic
                conditions or changing circumstances are more likely to lead
                to a weakened capacity to pay interest and repay principal
                for debt in this category than in higher rated categories.
 
    BB          Debt rated 'BB', 'B', 'CCC', 'CC' and 'C' is regarded as
    B           having predominantly speculative with respect to capacity to
    CCC         pay interest and repay principal. 'BB' indicates the lowest
    CC          degree of speculation and 'C' the highest. While such debt
    C           will likely have some quality and protective
                characteristics, these are outweighed by large uncertainties
                or large exposures to adverse conditions.
 
    BB          Debt rated 'BB' has less near-term vulnerability to default
                than other speculative issues. However, it faces major
                ongoing uncertainties or exposure to adverse business,
                financial, or economic conditions which could lead to
                inadequate capacity to meet timely interest and principal
                payments. The 'BB' rating category is also used for debt
                subordinated to senior debt that is assigned an actual or
                implied 'BBB-' rating.
</TABLE>
 
                                      B-18
<PAGE>   707
    B           Debt rated 'B' has a greater vulnerability to default but
                currently has the capacity to meet interest payments and
                principal repayments. Adverse business, financial, or
                economic conditions will likely impair capacity or
                willingness to pay interest and repay principal. The 'B'
                rating category is also used for debt subordinated to senior
                debt that is assigned an actual or implied 'BB' or 'BB-'
                rating.
 
    CCC         Debt rated 'CCC' has a currently identifiable vulnerability
                to default, and is dependent upon favorable business,
                financial, and economic conditions to meet timely payment of
                interest and repayment of principal. In the event of adverse
                business, financial, or economic conditions, it is not
                likely to have the capacity to pay interest and repay
                principal. The 'CCC' rating category is also used for debt
                subordinated to senior debt that is assigned an actual or
                implied 'B' or 'B-' rating.
 
    CC          The rating 'CC' typically is applied to debt subordinated to
                senior debt that is assigned an actual or implied 'CCC'
                rating.
 
    C           The rating 'C' typically is applied to debt subordinated to
                senior debt which is assigned an actual or implied 'CCC-'
                debt rating. The 'C' rating may be used to cover a situation
                where a bankruptcy petition has been filed, but debt service
                payments are continued.
 
    CI          The rating 'CI' is reserved for income bonds on which no
                interest is being paid.
 
    D           Debt rated 'D' is in payment default. The 'D' rating
                category is used when interest payments or principal
                payments are not made on the date due even if the applicable
                grace period has not expired, unless S&P believes that such
                payments will be made during such grace period. The 'D'
                rating also will be used upon the filing of a bankruptcy
                petition if debt service payments are jeopardized.
 
           PLUS (+) or MINUS (-): The ratings from 'AA' to 'CCC' may be modified
           by the addition of a plus or minus sign to show relative standing
           within the major categories.
 
<TABLE>
    <S>         <C>
    C           The letter "c" indicates that the holder's option to tender
                the security for purchase may be canceled under certain
                prestated conditions enumerated in the tender option
                documents.
 
    I           The letter "i" indicates the rating is implied. Such ratings
                are assigned only on request to entities that do not have
                specific debt issues to be rated. In addition, implied
                ratings are assigned to governments that have not requested
                explicit ratings for specific debt issues. Implied ratings
                on governments represent the sovereign ceiling or upper
                limit for ratings on specific debt issues of entities
                domiciled in the country.
 
    L           The letter "L" indicates that the rating pertains to the
                principal amount of those bonds to the extent that the
                underlying deposit collateral is federally insured and
                interest is adequately collateralized. In the case of
                certificates of deposit, the letter "L" indicates that the
                deposit, combined with other deposits being held in the same
                right and capacity, will be honored for principal and
                accrued pre-default interest up to the federal insurance
                limits within 30 days after closing of the insured
                institution or, in the event that the deposit is assumed by
                a successor insured institution, upon maturity.
 
    P           The letter "p" indicates that the rating is provisional. A
                provisional rating assumes the successful completion of the
                project being financed by the debt being rated and indicates
                that payment of debt service requirements is largely or
                entirely dependent upon the successful and timely completion
                of the project. This rating, however, while addressing
                credit quality subsequent to completion of the project,
                makes no comment on the likelihood of, or the risk of
                default upon failure of, such completion. The investor
                should exercise his own judgement with respect to such
                likelihood and risk.
                *Continuance of the rating is contingent upon S&P's receipt
                of an executed copy of the escrow agreement or closing
                documentation confirming investments and cash flows.
</TABLE>
 
                                      B-19
<PAGE>   708
    NR          Indicates that no public rating has been requested, that
                there is insufficient information on which to base a rating,
                or that S&P does not rate a particular type of obligation as
                a matter of policy.
 
  Debt Obligations of issuers outside the United States and its territories are
rated on the same basis as domestic corporate and municipal issues. The ratings
measure the creditworthiness of the obligor but do not take into account
currency exchange and related uncertainties.
 
  Bond Investment Quality Standards: Under present commercial bank regulations
issued by the Comptroller of the Currency, bonds rated in the top four
categories ("AAA", "AA", "A", "BBB", commonly known as "investment grade"
ratings) are generally regarded as eligible for bank investment. In addition,
the laws of various states governing legal investments impose certain rating or
other standards for obligations eligible for investment by savings banks, trust
companies, insurance companies and fiduciaries generally.
 
     2.  MUNICIPAL NOTES
 
          A S&P note rating reflects the liquidity concerns and market access
     risks unique to notes. Notes due in 3 years or less will likely receive a
     note rating. Notes maturing beyond 3 years will most likely receive a
     long-term debt rating.
 
          The following criteria will be used in making that assessment.
 
          -- Amortization schedule (the larger the final maturity relative to
             other maturities, the more likely it will be treated as a note).
 
          -- Source of payment (the more dependent the issue is on the market
             for its refinancing, the more likely it will be treated as a note).
 
        Note rating symbols are as follows:
 
<TABLE>
    <S>         <C>
    SP-1        Strong or strong capacity to pay principal and interest.
                Issues determined to possess very strong characteristics are
                a plus (+) designation.
 
    SP-2        Satisfactory capacity to pay principal and interest, with
                some vulnerability to adverse Financial and economic changes
                over the term of the notes.
 
    SP-3        Speculative capacity to pay principal and interest.
</TABLE>
 
     3.  COMMERCIAL PAPER
 
          A S&P 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. Ratings are graded into several categories, ranging from
     'A-1' for the highest quality obligations to 'D' for the lowest. These
     categories are as follows:
 
<TABLE>
    <S>         <C>
    A-1         This highest category indicates that the degree of safety
                regarding timely payment is strong. Those issues determined
                to possess extremely strong safety characteristics are
                denoted with a plus (+) sign designation.
 
    A-2         Capacity for timely payment on issues with this designation
                is satisfactory. However, the relative degree of safety is
                not as high as for issues designated 'A-1'.
 
    A-3         Issues carrying this designation have adequate capacity for
                timely payment. They are, however, more vulnerable to the
                adverse effects of changes in circumstances than obligations
                carrying the higher designations.
 
    B           Issues rated 'B' are regarded as having only speculative
                capacity for timely payment.
 
    C           This rating is assigned to short-term debt obligations with
                a doubtful capacity for payment.
 
    D           Debt rated 'D' is in payment default. The 'D' rating
                category is used when interest payments or principal
                payments are not made on the date due, even if the
                applicable grace period has not expired, unless S&P believes
                that such payments will be made during such grace period.
</TABLE>
 
                                      B-20
<PAGE>   709
    A commercial paper rating is not a recommendation to purchase or sell a
    security. The ratings are based on current information furnished to S&P
    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.
 
     4.  TAX-EXEMPT DUAL RATINGS
 
          S&P assigns "dual" ratings to all municipal debt issues that have a
     demand or double feature as part of their provisions.
 
          The first rating addresses the likelihood of repayment of principal
     and interest as due, and the second rating addresses only the demand
     feature. The long-term debt rating symbols are used for bonds to denote the
     long-term maturity and the commercial paper rating symbols are used to
     denote the put option (for example, 'AAA/A-1+'). With short-term demand
     debt, S&P's note rating symbols are used with the commercial paper symbols
     (for example, 'SP-1+/A-1+').
 
  MOODY'S INVESTORS SERVICE, INC.--A brief description of the applicable Moody's
Investors Service, Inc. ("Moody's") rating symbols and their meanings (as
published by Moody's) follows:
 
     1.  LONG-TERM MUNICIPAL BONDS
 
<TABLE>
    <S>         <C>
    AAA         Bonds which are rated Aaa are judged to be of the best
                quality. They carry the smallest degree of investment risk
                and are generally referred to as "gilt edged." Interest
                payments are protected by a large or by an exceptionally
                stable margin and principal is secure. While the various
                protective elements are likely to change, such changes as
                can be visualized are most unlikely to impair the
                fundamentally strong position of such issues.
 
    AA          Bonds which are rated Aa are judged to be of high quality by
                all standards. Together with the Aaa group they comprise
                what are generally known as high grade bonds. They are rated
                lower than the best bonds because margins of protection may
                not be as large as in Aaa securities or fluctuation of
                protective elements may be of greater amplitude or there may
                be other elements present which make the long-term risk
                appear somewhat larger than the Aaa securities.
 
    A           Bonds which are rated A possess many favorable investment
                attributes and are to be considered as upper-medium-grade
                obligations. Factors giving security to principal and
                interest are considered adequate, but elements may be
                present which suggest a susceptibility to impairment some
                time in the future.
 
    BAA         Bonds which are rated Baa are considered as medium-grade
                obligations, (i.e., they are neither highly protected nor
                poorly secured). Interest payments and principal security
                appear adequate for the present but certain protective
                elements may be lacking or may be characteristically
                unreliable over any great length of time. Such bonds lack
                outstanding investment characteristics and in fact have
                speculative characteristics as well.
 
    BA          Bonds which are rated Ba are judged to have speculative
                elements; their future cannot be considered as well-assured.
                Often the protection of interest and principal payments may
                be very moderate, and thereby not well safeguarded during
                both good and bad times over the future. Uncertainty of
                position characterizes bonds in this class.
 
    B           Bonds which are rated B generally lack characteristics of
                the desirable investment. Assurance of interest and
                principal payments or of maintenance of other terms of the
                contract over any long period of time may be small.
 
    CAA         Bonds which are rated Caa are of poor standing. Such issues
                may be in default or there may be present elements of danger
                with respect to principal or interest.
 
    CA          Bonds which are rated Ca represent obligations which are
                speculative in a high degree. Such issues are often in
                default or have other marked shortcomings.
</TABLE>
 
                                      B-21
<PAGE>   710
   
    C           Bonds which are rated C are the lowest rated class of bonds,
                and issues so rated can be regarded as having extremely poor
                prospects of ever attaining any real investment standing.
 
    CON (..)    Bonds for which the security depends upon the completion of
                some act or the fulfillment of some condition are rated
                conditionally and designated with the prefix "Con" followed
                by the rating in parentheses. These are bonds secured by (a)
                earnings of projects under construction, (b) earnings of
                projects unseasoned in operation experience, (c) rentals
                which begin when facilities are completed, or (d) payments
                to which some other limiting condition attaches the
                parenthetical rating denotes probable credit stature upon
                completion of construction or elimination of basis of
                condition.
 
    (P) (..)    When applied to forward delivery bonds, indicates that the
                rating is provisional pending the delivery of the bonds. The
                rating may be revised prior to delivery if changes occur in
                the legal documents or the underlying credit quality of the
                bonds.
 
    NOTE:       Moody's applies numerical modifiers, 1, 2 and 3 in each
                generic rating classification from AA to B. The modifier 1
                indicates that the company ranks in the higher end of its
                generic rating category; the modifier 2 indicates a
                mid-range ranking; and the modifier 3 indicates that the
                company ranks in the lower end of its generic rating
                category.
 
    
 
     2.  SHORT-TERM EXEMPT NOTES
 
          Moody's ratings for state and municipal short-term obligations will be
     designated Moody's Investment Grade or (MIG). Such ratings recognize the
     differences between short-term credit risk and long-term risk. Factors
     affecting the liquidity of the borrower and short-term cyclical elements
     are critical in short-term ratings, while other factors of major importance
     in bond risk, long-term secular trends for example, may be less important
     over the short run. A short-term rating may also be assigned on an issue
     having a demand feature-variable rate demand obligation. Such ratings will
     be designated as VMIG, SG or, if the demand feature is not rated, as NR.
 
          Moody's short-term ratings are designated Moody's Investment Grade as
     MIG 1 or VMIG 1 through MIG 4 or VMIG 4. As the name implies, when Moody's
     assigns a MIG or VMIG rating, all categories define an investment grade
     situation.
 
          MIG 1/VMIG 1. This designation denotes best quality. There is present
     strong protection by established cash flows, superior liquidity support or
     demonstrated broadbased access to the market for refinancing.
 
          MIG 2/VMIG 2. This designation denotes high quality. Margins of
     protection are ample although not so large as in the preceding group.
 
          MIG 3/VMIG 3. This designation denotes favorable quality. All security
     elements are accounted for but there is lacking the undeniable strength of
     the preceding grades. Liquidity and cash flow protection may be narrow and
     market access for refinancing is likely to be less well established.
 
          MIG 4/VMIG 4. This designation denotes adequate quality. Protection
     commonly regarded as required of an investment security is present and
     although not distinctly or predominantly speculative, there is specific
     risk.
 
          SG. This designation denotes speculative quality. Debt instruments in
     this category lack margins of protection.
 
     3.  TAX-EXEMPT COMMERCIAL PAPER
 
   
          Moody's short-term debt ratings are opinions of the ability of issuers
     to repay punctually promissory obligations not having an original maturity
     in excess of nine months. Moody's makes no representation that such
     obligations are exempt from registration under the Securities Act of 1933,
     not does it represent that any specific note is a valid obligation of a
     rated issuer or issued in conformity with any applicable law.

          Moody's employs the following three designations, all judged to be
     investment grade, to indicate the relative repayment ability of rated
     issuers:
 
   
          Issuers rated Prime-1 (for related supporting institutions) have a
     superior capacity for repayment of short-term promissory obligations.
     Prime-1 repayment capacity will normally be evidenced by the following
     characteristics:
    
 
   
           -- Leading market positions in well established industries.
    
 
   
           -- High rates of return on funds employed.
    
 
   
           -- Conservative capitalization structures with moderate reliance on
              debt and ample asset protection.
    
 
   
           -- Broad margins in earning coverage of fixed financial charges and
              high internal cash generation.
    
 
   
           -- Well established access to a range of financial markets and
              assured sources of alternative liquidity.
    
 
   
          Issuers rated Prime-2 (or related supporting institutions) have a
     strong capacity for repayment of short-term promissory obligations. This
     will normally be evidenced by many of the characteristics cited above but
     to a lesser degree. Earnings trends and coverage ratios, while sound, will
     be more subject to variation. Capitalization characteristics, while still
     appropriate, may be more affected by external conditions. Ample alternate
     liquidity is maintained.
    
 
   
          Issuers rated Prime-3 (or related supported institutions) have an
     acceptable capacity for repayment of short-term promissory obligations. The
     effects of industry characteristics and market composition may be more
     pronounced. Variability in earnings and profitability may result in changes
     in the level of debt protection measurements and the requirement for
     relatively high financial leverage. Adequate alternate liquidity is
     maintained.
    
 
   
          Issuers rated Not Prime do not fall within any of the Prime rating
     categories.
    
 
         DESCRIPTION OF INSURANCE COMPANY CLAIMS PAYING ABILITY RATINGS
 
RATINGS OF INSURANCE COMPANY CLAIMS-PAYING ABILITY
 
  The claims-paying ability of insurance companies is rated by S&P and Moody's.
Descriptions of these ratings are set forth below:
 
DESCRIPTION OF S&P'S RATINGS OF INSURANCE COMPANY CLAIMS-PAYING ABILITY
 
  AAA. Superior financial security on an absolute and relative basis. Capacity
to meet policyholder obligations is overwhelming under a variety of economic and
underwriting conditions.
 
  AA. Excellent financial security. Capacity to meet policyholder obligations is
strong under a variety of economic and underwriting conditions.
 
  A. Good financial security, but capacity to meet policyholder obligations is
somewhat susceptible to adverse economic and underwriting conditions.
 
  BBB. Adequate financial security, but capacity to meet policyholder
obligations is susceptible to adverse economic and underwriting conditions.
 
Note: Plus (+) and minus (-) signs indicate relative standing within a category,
and are not indications of likely upgrades or downgrades.
 
                                      B-23
<PAGE>   712
 
DESCRIPTION OF MOODY'S RATINGS OF INSURANCE COMPANY CLAIMS-PAYING ABILITY
 
  AAA. Insurance companies rated Aaa offer exceptional financial security. While
the financial strength of these companies is likely to change, such changes as
can be visualized are most unlikely to impair their fundamentally strong
position.
 
  AA. Insurance companies rated Aa offer excellent financial security. Together
with the Aaa group they constitute what are generally known as high grade
companies. They are rated lower than Aaa companies because long-term risks
appear somewhat larger.
 
  A. Insurance companies rated A offer good financial security. However,
elements may be present which suggest a susceptibility to impairment sometime in
the future.
 
  BAA. Insurance companies rated Baa offer adequate financial security. However,
certain protective elements may be lacking or may be characteristically
unreliable over any great length of time.
 
Note: Numeric modifiers are used to refer to the ranking within the group -- one
being the highest and three being the lowest. However, the financial strength of
companies within a generic rating symbol (Aa, for example) is broadly the same.

  Each of the trustees holds the same position with each of the funds in the
Fund Complex. As of December 31, 1996, there were 51 funds in the Fund Complex.
Each trustee who is not an affiliated person of VKAC, the Advisers, the
Distributor, ACCESS or Morgan Stanley (each a "Non-Affiliated Trustee") is
compensated by an annual retainer and meeting fees for services to the funds in
the Fund Complex. Each fund in the Fund Complex provides a deferred compensation
plan to its Non-Affiliated Trustees that allows trustees to defer receipt of
their compensation and earn a return on such deferred amounts based upon the
return of the common shares of the funds in the Fund Complex as more fully
described below. Each fund in the Fund Complex also provides a retirement plan
to its Non-Affiliated Trustees that provides Non-Affiliated Trustees with
compensation after retirement, provided that certain eligibility requirements
are met as more fully described below.
    
 
   
  The compensation of each Non-Affiliated Trustee from each fund in the Fund
Complex advised by Advisory Corp. (each a "VK Fund" and collectively the "VK
Funds") includes an annual retainer in an amount equal to $2,500 per calendar
year, due in four quarterly installments on the first business day of each
calendar quarter. Each Non-Affiliated Trustee receives a per meeting fee from
each VK Fund in the amount of $125 per regular quarterly meeting attended by the
Non-Affiliated Trustee, due on the date of such meeting, plus reasonable
expenses incurred by the Non-Affiliated Trustee in connection with his or her
services as a trustee. Each Non-Affiliated Trustee receives a per meeting fee
from each VK Fund in the amount of $125 per special meeting attended by the
Non-Affiliated Trustee, due on the date of such meeting, plus reasonable
expenses incurred by the Non-Affiliated Trustee in connection with his or her
services as a trustee, provided that no compensation will be paid in connection
with certain telephonic special meetings.
    
 
   
  The compensation of each Non-Affiliated Trustee from the funds in the Fund
Complex advised by Asset Management (each an "AC Fund" or collectively the "AC
Funds") includes an annual retainer in an amount equal to $35,000 per calendar
year, due in four quarterly installments on the first business day of each
calendar quarter. The AC Funds pay each Non-Affiliated Trustee a per meeting fee
in the amount of $2,000 per regular quarterly meeting attended by the
Non-Affiliated Trustee, due on the date of such meeting, plus reasonable
    
 
                                      B-28
<PAGE>   717
 
   
expenses incurred by the Non-Affiliated Trustee in connection with his or her
services as a trustee. Payment of the annual retainer and the regular meeting
fee is allocated among the AC Funds (i) 50% on the basis of the relative net
assets of each AC Fund to the aggregate net assets of all the AC Funds and (ii)
50% equally to each AC Fund, in each case as of the last business day of the
preceding calendar quarter. Each AC Fund which is the subject of a special
meeting of the trustees generally pays each Non-Affiliated Trustee a per meeting
fee in the amount of $125 per special meeting attended by the Non-Affiliated
Trustee, due on the date of such meeting, plus reasonable expenses incurred by
the Non-Affiliated Trustee in connection with his or her services as a trustee,
provided that no compensation will be paid in connection with certain telephonic
special meetings.
    
 
   
  The trustees approved an aggregate compensation cap with respect to funds in
the Fund Complex of $84,000 per Non-Affiliated Trustee per year (excluding any
retirement benefits) for the period July 22, 1995 through December 31, 1996,
subject to the net assets and the number of funds in the Fund Complex as of July
21, 1995 and certain other exceptions. For the calendar year ended December 31,
1996, certain trustees received aggregate compensation from the funds in the
Fund Complex over $84,000 due to compensation received but not subject to the
cap, including compensation from new funds added to the Fund Complex after July
22, 1995 and certain special meetings in 1996. In addition, each of Advisory
Corp. or Asset Management, as the case may be, agreed to reimburse each fund in
the Fund Complex through December 31, 1996 for any increase in the aggregate
trustee's compensation over the aggregate compensation paid by such fund in its
1994 fiscal year, provided that if a fund did not exist for the entire 1994
fiscal year appropriate adjustments will be made.
    
 
   
  Each Non-Affiliated Trustee generally can elect to defer receipt of all or a
portion of the compensation earned by such Non-Affiliated Trustee until
retirement. Amounts deferred are retained by the Fund and earn a rate of return
determined by reference to the return on the common shares of such Fund or other
funds in the Fund Complex as selected by the respective Non-Affiliated Trustee,
with the same economic effect as if such Non-Affiliated Trustee had invested in
one or more funds in the Fund Complex. To the extent permitted by the 1940 Act,
the Fund may invest in securities of those funds selected by the Non-Affiliated
Trustees in order to match the deferred compensation obligation. The deferred
compensation plan is not funded and obligations thereunder represent general
unsecured claims against the general assets of the Fund.
    
 
   
  Each fund in the Fund Complex has adopted a retirement plan. Under the Fund's
retirement plan, a Non-Affiliated Trustee who is receiving trustee's
compensation from the Fund prior to such Non-Affiliated Trustee's retirement,
has at least 10 years of service (including years of service prior to adoption
of the retirement plan) and retires at or after attaining the age of 60, is
eligible to receive a retirement benefit equal to $2,500 per year for each of
the ten years following such trustee's retirement from the Fund. Trustees
retiring prior to the age of 60 or with fewer than 10 years but more than 5
years of service may receive reduced retirement benefits from the Fund. Each
trustee has served as a member of the Board of Trustees since he or she was
first appointed or elected in the year set forth below. The retirement plan
contains a Fund Complex retirement benefit cap of $60,000 per year. Asset
Management has reimbursed each AC Fund for the expenses related to the
retirement plan through December 31, 1996.
    
 
   
  Additional information regarding compensation and benefits for trustees is set
forth below. As indicated in the notes accompanying the table, the amounts
relate to either the Trust's most recently completed fiscal year or the Fund
Complex' most recently completed calendar year ended December 31, 1996.

*  Currently a member of the Board of Trustees. Mr. Phillip B. Rooney also is a
   current member of the Board of Trustees but is not included in the
   compensation table because he did not serve on the Board of Trustees or
   receive any compensation from the Trust prior to April 14, 1997. Messrs.
   McDonnell and Powell, also trustees of the Trust during all or a portion of
   the Trust's last fiscal year, are not included in the compensation table
   because they are affiliated persons of the Advisers and are not eligible for
   compensation or retirement benefits from the Trust.
    
 
   
(1) Persons not designated by an asterisk are not currently members of the Board
    of Trustees, but were members of the Board of Trustees during the Trust's
    most recently completed fiscal year. Messrs. Gaughan and Rees retired from
    the Board of Trustees on January 26, 1996 and January 29, 1996,
    respectively. Mr. Sheehan was removed from the Board of Trustees effective
    January 29, 1996. Messrs. Hilsman, Miller and Woodside retired from the
    Board of Trustees on December 31, 1996.
    
 
   
(2) The amounts shown in this column represent the aggregate compensation before
    deferral from all eight series of the Trust, including the Fund, with
    respect to the Trust's fiscal year ended December 31, 1996. The detail of
    aggregate compensation before deferral for each series, including the Fund,
    are shown in Table A below. Certain trustees deferred compensation from the
    Trust during the fiscal year ended December 31, 1996; the aggregate
    compensation deferred from all eight series of the Trust, including the
    Fund, is as follows: Mr. Branagan, $5,750; Mr. Gaughan, $3,750; Ms. Heagy,
    $15,000; Mr. Kennedy, $9,500; Mr. Miller, $20,000; Mr. Nelson, $20,000; Mr.
    Robinson, $18,000; and Mr. Whalen, $19,625. The details of amounts deferred
    for each series, including the Fund, are shown in Table B below. Amounts
    deferred are retained by the respective fund and earn a rate of return
    determined by reference to either the return on the common shares of such
    fund or other funds in the Fund Complex as selected by the respective
    Non-Affiliated Trustee, with the same economic effect as if such
    Non-Affiliated Trustee had invested in one or more funds in the Fund
    Complex. To the extent permitted by the 1940 Act, each fund may invest in
    securities of those funds selected by the Non-Affiliated Trustees in order
    to match the deferred compensation obligation. The cumulative deferred
    compensation (including interest) accrued with respect to each trustee from
    all eight series of the Trust, including the Fund, as of the Trust's fiscal
    year ended December 31, 1996 is as follows: Mr. Branagan, $5,678; Mr.
    Gaughan, $20,094; Ms. Heagy, $20,472; Mr. Kennedy, $47,294; Mr. Miller,
    $55,827; Mr. Nelson, $57,771; Mr. Robinson, $54,847; and Mr. Whalen,
    $49,269. The details of cumulative deferred compensation (including
    interest) for each

    series, including the Fund, are shown in Table C below. The deferred
    compensation plan is described above the Compensation Table.
    
 
   
(3) The amounts shown in this column represent the retirement benefits accrued
    by all eight series of the Trust, including the Fund, with respect to the
    Trust's fiscal year ended December 31, 1996. The details of retirement
    benefits accrued for each series, including the Fund, are shown in Table D
    below. The retirement plan is described above the Compensation Table.
    
 
   
(4) This is the estimated maximum annual benefits payable by the Trust in each
    year of the 10-year period commencing in the year of such trustee's
    retirement from the Trust. The estimated maximum annual benefit, except for
    trustees who have retired or are near retirement, is based upon $2,500 per
    series assuming: the trustee has 10 or more years of service on the Board of
    Trustees (including years of service prior to the adoption of the retirement
    plan) and retires at or after attaining the age of 60. Trustees retiring
    prior to the age of 60 or with fewer than 10 years of service for a series
    of the Trust may receive reduced retirement benefits from such series. The
    actual annual benefit may be less if the trustee is subject to the Fund
    Complex retirement benefit cap or if the trustee is not fully vested at the
    time of retirement. Each Non-Affiliated Trustee of the Board of Trustees has
    served as a member of the Board of Trustees since he or she was first
    appointed or elected in the year set forth in Table E below.
    
 
   
(5) The amounts shown in this column represent the aggregate compensation paid
    by all 51 of the investment companies in the Fund Complex as of December 31,
    1996 before deferral by the trustees under the deferred compensation plan.
    Certain trustees deferred all or a portion of their aggregate compensation
    from the Fund Complex during the calendar year ended December 31, 1996. The
    deferred compensation earns a rate of return determined by reference to the
    return on the shares of the funds in the Fund Complex as selected by the
    respective Non-Affiliated Trustee, with the same economic effect as if such
    Non-Affiliated Trustee had invested in one or more funds in the Fund
    Complex. To the extent permitted by the 1940 Act, the Fund may invest in
    securities of those investment companies selected by the Non-Affiliated
    Trustees in order to match the deferred compensation obligation. The
    trustees' Fund Complex compensation cap covered the period July 22, 1995
    through December 31, 1996. For the calendar year ended December 31, 1996,
    certain trustees received compensation over $84,000 in the aggregate due to
    compensation received but not subject to the cap, including compensation
    from new funds added to the Fund Complex after July 22, 1995 and certain
    special meetings in 1996. The Advisers and their affiliates also serve as
    investment adviser for other investment companies; however, with the
    exception of Messrs. McDonnell, Powell and Whalen, the trustees were not
    trustees of such investment companies. Combining the Fund Complex with other
    investment companies advised by the Advisers and their affiliates, Mr.
    Whalen received Total Compensation of $243,375 during the calendar year
    ended December 31, 1996.
    
 
   
  As of April 4, 1997, the trustees and officers of the Fund as a group owned
less than 1% of the shares of the Fund.

matters to which the agreement relates, except a loss resulting from willful
misfeasance, bad faith, or gross negligence on the part of the Adviser in the
performance of its obligations and duties, or by reason of its reckless
disregard of its obligations and duties under the agreement.
 
  The Adviser's activities are subject to the review and supervision of the
Board of Trustees of the Trust, of which the Fund is a series, to whom the
Adviser renders periodic reports of the Fund's investment activities.
 
  The agreement will continue in effect from year to year if specifically
approved by the Trustees of the Trust, of which the Fund is a separate series
(or by the Fund's shareholders), and by the disinterested trustees in compliance
with the requirements of the 1940 Act. The agreement may be terminated without
penalty upon 60 days' written notice by either party thereto and will
automatically terminate in the event of assignment.
 
  The investment advisory agreement specifies that the Adviser will reimburse
the Fund for annual expenses of the Fund which exceed the most stringent limit
prescribed by any state in which the Fund's shares are offered for sale.
Currently, the most stringent limit in any state would require such
reimbursement to the extent that aggregate operating expenses of the Fund
(excluding interest, taxes and other expenses which may be excludable under
applicable state law) exceed in any fiscal year 2 1/2% of the average annual net
assets of the Fund up to $30 million, 2% of the average annual net assets of the
Fund of the next $70 million, and 1 1/2% of the remaining average annual net
assets of the Fund. In addition to making any required reimbursements, the
 
                                      B-34
<PAGE>   723
 
Adviser may in its discretion, but is not obligated to, waive all or any portion
of its fee or assume all or any portion of the expenses of the Fund.
 
   
  For the years ended December 31, 1996, 1995 and 1994, the Fund paid advisory
expenses of $0, $0 and $0, respectively.
    
 
OTHER AGREEMENTS
 
   
  ACCOUNTING SERVICES AGREEMENT.  The Fund has also entered into an accounting
services agreement pursuant to which the Adviser provides accounting services
supplementary to those provided by the Custodian. Such services are expected to
enable the Fund to more closely monitor and maintain its accounts and records.
The Fund shares together with the other Van Kampen American Capital mutual funds
in the cost of providing such services, with 25% of such costs shared
proportionately based on the respective number of classes of securities issued
per fund and the remaining 75% of such cost based proportionally on their
respective net assets per fund.
    
 
   
  For the years ended December 31, 1996, 1995 and 1994 the Fund paid expenses of
approximately $0, $0 and $942, respectively, representing the Adviser's cost of
providing accounting services.
    
 
   
  LEGAL SERVICES AGREEMENT.  The Fund and each of the other Van Kampen American
Capital funds advised by the Adviser and distributed by the Distributor have
entered into Legal Services Agreements pursuant to which Van Kampen American
Capital provides legal services, including without limitation: accurate
maintenance of the fund's minute books and records, preparation and oversight of
the fund's regulatory reports, and other information provided to shareholders,
as well as responding to day-to-day legal issues on behalf of the funds. Payment
by the Fund for such services is made on a cost basis for the salary and salary
related benefits, including but not limited to bonuses, group insurances and
other regular wages for the employment of personnel, as well as overhead and the
expenses related to the office space and the equipment necessary to render the
legal services. Other funds distributed by the Distributor also receive legal
services from Van Kampen American Capital. Of the total costs for legal services
provided to funds distributed by the Distributor, one half of such costs are
allocated equally to each fund and the remaining one half of such costs are
allocated to specific funds based on monthly time records.
    
 
   
  For the years ended December 31, 1996, 1995 and 1994 the Fund paid expenses of
approximately $0, $0 and $0, respectively, representing Van Kampen American
Capital's cost of providing legal services.
    
 
   
                     CUSTODIAN AND INDEPENDENT ACCOUNTANTS
    
 
  State Street Bank and Trust Company, 225 Franklin Street, P.O. Box 1713,
Boston, MA 02105-1713, is the custodian of the Fund and has custody of all
securities and cash of the Fund. The custodian, among other things, attends to
the collection of principal and income, and payment for and collection of
proceeds of securities bought and sold by the Fund.
 
   
  The independent accountants for the Fund are KPMG Peat Marwick LLP, Chicago,
Illinois. The selection of independent accountants will be subject to
ratification by the shareholders of the Fund at any annual meeting of
shareholders.
    
 
                PORTFOLIO TRANSACTIONS AND BROKERAGE ALLOCATION
 
  The Adviser will place orders for portfolio transactions for the Fund with
broker-dealer firms giving consideration to the quality, quantity and nature of
each firm's professional services. These services include execution, clearance
procedures, wire service quotations and statistical and other research
information provided to the Fund, or the Adviser, including quotations necessary
to determine the value of the Fund's net assets. Any research benefits derived
are available for all clients of the Adviser. Since statistical and other
research information is only supplementary to the research efforts of the
Adviser to the Fund and still must be analyzed and reviewed by its staff, the
receipt of research information is not expected to materially reduce its
expenses. In selecting among the firms believed to meet the criteria for
handling a particular transaction, the Fund's Adviser may take into
consideration that certain firms have sold or are selling shares of the Fund and
 
                                      B-35
<PAGE>   724
 
that certain firms provide market, statistical or other research information to
the Fund and the Adviser, and may select firms that are affiliated with the
Fund, the Adviser, or its distributor and other principal underwriters.
 
  If it is believed to be in the best interests of the Fund, the Adviser may
place portfolio transactions with brokers who provide the types of service
described above, even if it means the Fund will have to pay a higher commission
(or, if the broker's profit is part of the cost of the security, will have to
pay a higher price for the security), than would be the case if no weight were
given to the broker's furnishing of those research services. This will be done,
however, only if, in the opinion of the Fund's Adviser, the amount of additional
commission or increased cost is reasonable in relation to the value of such
services.
 
  In selecting among the firms believed to meet the criteria for handling a
particular transaction, the Adviser may take into consideration that certain
firms (i) provide market, statistical or other research information such as that
set forth to the Fund and the Adviser, (ii) have sold or are selling shares of
the Fund and (iii) may select firms that are affiliated with the Fund, its
investment adviser or its distributor or other principal underwriters. If
purchases or sales of securities of the Fund and of one or more other investment
companies or clients supervised by the Adviser are considered at or about the
same time, transactions in such securities will be allocated among the several
investment companies and clients in a manner deemed equitable to all by the
Adviser, taking into account the respective sizes of the Fund and other
investment companies and clients and the amount of securities to be purchased or
sold. Although it is possible that in some cases this procedure could have a
detrimental effect on the price or volume of the security as far as the Fund is
concerned, it is also possible that the ability to participate in volume
transactions and to negotiate lower brokerage commissions will be beneficial to
the Fund.
 
  While the Adviser will be primarily responsible for the placement of the
Fund's business, the policies and practices in this regard must be consistent
with the foregoing and will at all times be subject to review by the trustees of
the Trust, of which the Fund is a separate series.
 
  The trustees have adopted certain policies incorporating the standards of Rule
17e-1 issued by the SEC under the 1940 Act which requires that the commissions
paid to the Distributor and other affiliates of the Fund must be reasonable and
fair compared to the commissions, fees or other remuneration received or to be
received by other brokers in connection with comparable transactions involving
similar securities during a comparable period of time. The rule and procedures
also contain review requirements and require the Adviser to furnish reports to
the trustees and to maintain records in connection with such reviews. After
consideration of all factors deemed relevant, the Trustees will consider from
time to time whether the advisory fee for the Fund will be reduced by all or a
portion of the brokerage commission given to affiliated brokers.
 
  State securities laws may differ from the interpretations of federal law
expressed herein, and banks and financial institutions may be required to
register as dealers pursuant to state law.
 
                             TAX STATUS OF THE FUND
 
   
  The Trust and any of its series, including the Fund, will be treated as
separate corporations for federal income tax purposes. The Fund intends to
qualify each year and to elect to be treated as a regulated investment company
under the Code. If the Fund so qualifies and distributes each year to its
shareholders at least 90% of its net investment income (including tax-exempt
interest, taxable income and net short-term capital gain, but not net capital
gains, which are the excess of long-term capital gains over net short-term
capital losses) in each year, it will not be required to pay federal income
taxes on any income distributed to shareholders. The Fund intends to distribute
at least the minimum amount of net investment income necessary to satisfy the
90% distribution requirement. The Fund will not be subject to federal income tax
on any net capital gains distributed to shareholders.
    
 
   
  The table below illustrates approximate equivalent taxable and tax-free yields
at the 1997 federal individual income tax rates in effect on the date of this
Statement of Additional Information, including the 36% and 39.6% rates enacted
in August 1993 as part of the Revenue Reconciliation Act of 1993.
    
 
                                      B-36

  The table shows, for example, that a couple with a taxable income of $90,000,
or a single individual with a taxable income of $55,000, whose investments earn
a 6% tax-free yield, would have to earn approximately an 8.3% taxable yield at
current federal income tax rates to receive the same benefit.
 
  The State of Florida imposes no income tax on individuals; accordingly, the
table reflects only the exemption from Federal income taxes. The table does not
reflect the exemption of shares of the Fund from the State's intangible tax;
accordingly, Florida residents subject to such tax would need a somewhat higher
taxable return than those shown to equal the tax-exempt return of the Florida
Fund.

country, with more than 80 analysts devoted to various specializations. Each of
our high yield analysts, based either in San Francisco, Chicago, Houston or
Boston, has the responsibility to cover a specific region of the country. This
regional focus enables each high yield analyst to provide more specialized
coverage of the market and alert the portfolio manager to issues of local
importance.

has received purchase orders. A discussion of how to purchase and redeem the
Fund's shares and how the Fund's shares are priced is contained in the
Prospectus.
 
   
                         DISTRIBUTION AND SERVICE PLANS
    
 
  The Fund has adopted a distribution plan (the "Distribution Plan") with
respect to each class of its shares pursuant to Rule 12b-1 under the 1940 Act.
The Fund also has adopted a service plan (the "Service Plan") with respect to
each class of shares. The Distribution Plan and Service Plan sometimes are
referred to herein collectively as the "Plans". The Plans provide that the Fund
may spend a portion of the Fund's average daily net assets attributable to each
class of shares in connection with distribution of the respective class of
shares and in connection with the provision of ongoing services to shareholders
of such class, respectively. The Plans are being implemented through an
agreement (the "Distribution and Service Agreement") with the Distributor, and
sub-agreements between the Distributor and members of the NASD acting as
securities dealers and NASD members or eligible non-members acting as brokers or
agents and similar agreements between the Fund and financial intermediaries
acting as brokers (collectively, "Selling Agreements") that may provide for
their customers or clients certain services or assistance, which may include,
but not be limited to, processing purchase and redemption transactions,
establishing and maintaining shareholder accounts regarding the Fund, and such
other services as may be agreed to from time to time and as may be permitted by
applicable statute, rule or regulation. Brokers, dealers and financial
intermediaries that have entered into sub-agreements with the Distributor and
sell shares of the Fund are referred to herein as "financial intermediaries."
 
  The Distributor must submit quarterly reports to the Board of Trustees of the
Trust, of which the Fund is a series, setting forth separately by class of
shares all amounts paid under the Plans and the purposes for which such
expenditures were made, together with such other information as from time to
time is reasonably requested by the Trustees. The Plans provide that they will
continue in full force and effect from year to year so long as such continuance
is specifically approved by a vote of the Trustees, and also by a vote of the
disinterested Trustees, cast in person at a meeting called for the purpose of
voting on the Plans. Each of the Plans may not be amended to increase materially
the amount to be spent for the services described therein with respect to either
class of shares without approval by a vote of a majority of the outstanding
voting shares of such class, and all material amendments to either of the Plans
must be approved by the Trustees and also by the disinterested Trustees. Each of
the Plans may be terminated with respect to either class of shares at any time
by a vote of a majority of the disinterested Trustees or by a vote of a majority
of the outstanding voting shares of such class.
 
   
  For the fiscal year ended December 31, 1996, the Fund's aggregate expenses
under the Plans for Class A shares were $24,246 or 0.15% of the Class A shares'
average net assets. Such expenses were paid to reimburse the Distributor for
payments made to financial intermediaries for servicing Fund shareholders and
for administering the Plans. For the fiscal year ended December 31, 1996, the
Fund's aggregate expenses under the Plans for Class B shares were $155,764 or
0.90% of the Class B shares' average net assets. Such expenses were paid to
reimburse the Distributor for the following payments: $129,984 for commissions
and transaction fees paid to financial intermediaries in respect of sales of
Class B shares of the Fund and $25,780 for fees paid to financial intermediaries
for servicing Class B shareholders and administering the Plans. For the fiscal
year ended December 31, 1996, the Fund's aggregate expenses under the Plans for
Class C shares were $3,546 or 0.91% of the Class C shares' average net assets.
Such expenses were paid to reimburse the Distributor for the following payments:
$2,913 for commissions and transaction fees paid to financial intermediaries in
respect of sales of Class C shares of the Fund and $633 for fees paid to
financial intermediaries for servicing Class C shareholders and administering
the Plans.

                            PERFORMANCE INFORMATION
 
  From time to time marketing materials may provide a portfolio manager update,
an adviser update or discuss general economic conditions and outlooks. The
Fund's marketing materials may also show the Fund's asset class diversification,
top five sectors, ten largest holdings and other Fund asset structures, such as
duration, maturity, coupon, NAV, rating breakdown, AMT exposure and number of
issues in the portfolio. Materials may also mention how Van Kampen American
Capital believes the Fund compares relative to other Van Kampen American Capital
funds. Materials may also discuss the Dalbar Financial Services study from 1984
to 1994 which studied investor cash flow into and out of all types of mutual
funds. The ten year study found that investors who bought mutual fund shares and
held such shares outperformed investors who bought and sold. The Dalbar study
conclusions were consistent regardless of if shareholders purchased their funds
in direct or sales force distribution channels. The study showed that investors
working with a professional representative have tended over time to earn higher
returns than those who invested directly. The Fund will also be marketed on the
Internet.
 
  The Fund's yield quotation is determined on a monthly basis with respect to
the immediately preceding 30 day period, and yield is computed by dividing the
Fund's net investment income per share of a given class earned during such
period by the Fund's maximum offering price (including, with respect to the
Class A Shares, the maximum initial sales charge) per share of such class on the
last day of such period. The Fund's net investment income per share is
determined by taking the interest attributable to a given class of shares earned
by the Fund during the period, subtracting the expenses attributable to a given
class of shares accrued for the period (net of any reimbursements), and dividing
the result by the average daily number of the shares of each class outstanding
during the period that were entitled to receive dividends. The yield calculation
formula assumes net investment income is earned and reinvested at a constant
rate and annualized at the end of a six month period. Yield will be computed
separately for each class of shares. Class B Shares redeemed during the first
seven years after their issuance and Class C Shares redeemed during the first
year after their issuance may be subject to a contingent deferred sales charge
in a maximum amount equal to 4.00% and 1.00%, respectively, of the lesser of the
then current net asset value of the shares redeemed or their initial purchase
price from the Fund. Yield quotations do not reflect the imposition of a
contingent deferred sales charge, and if any such contingent deferred sales
charge imposed at the time of redemption were reflected, it would reduce the
performance quoted.
 
  Tax-equivalent yield demonstrates the taxable yield required to produce an
after-tax yield equivalent to that of the Fund's yield. The Fund's
tax-equivalent yield quotation for a 30 day period as described above is
computed by dividing that portion of the yield of the Fund (as computed above)
which is tax-exempt by a percentage equal to 100% minus a stated percentage
income tax rate and adding the result to that portion of the Fund's yield, if
any, that is not tax-exempt.
 
  The Fund calculates average compounded total return by determining the
redemption value (less any applicable contingent deferred sales charge) at the
end of specified periods (after adding back all dividends and other
distributions made during the period) of a $1,000 investment in a given class of
shares of the Fund (less the maximum sales charge, if any) at the beginning of
the period, annualizing the increase or decrease over the specified period with
respect to such initial investment and expressing the result as a percentage.
Average compounded total return will be computed separately for each class of
shares.
 
  Total return figures utilized by the Fund are based on historical performance
and are not intended to indicate future performance. Total return and net asset
value per share of a given class can be expected to fluctuate over time, and
accordingly upon redemption a shareholder's shares may be worth more or less
than their original cost.
 
  The Fund may, in supplemental sales literature, advertise non-standardized
total return figures representing the cumulative, non-annualized total return of
each class of shares of the Fund from a given date to a subsequent given date.
Cumulative non-standardized total return is calculated by measuring the value of
an initial investment in a given class of shares of the Fund at a given time,
deducting the maximum initial sales charge, if any, determining the value of all
subsequent reinvested distributions, and dividing the net change in the value of
the investment as of the end of the period by the amount of the initial
investment and expressing the result as a percentage. Non-standardized total
return will be calculated separately for each class of shares.
 
                                      B-39
<PAGE>   728
 
Non-standardized total return calculations do not reflect the imposition of a
contingent deferred sales charge, and if any such contingent deferred sales
charge with respect to the CDSC imposed at the time of redemption were
reflected, it would reduce the performance quoted.
 
CLASS A SHARES
 
   
  The average annualized total return, including payment of the sales charge,

respect to the Class B Shares for the 30 day period ending December 30, 1995
(calculated in the manner described in the Prospectus under the heading "Fund
Performance" and assuming a 36% tax rate) was 6.72%. The Fund's current

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
The Board of Trustees and Shareholders of
Van Kampen American Capital Florida Insured Tax Free Income Fund:
 
We have audited the accompanying statement of assets and liabilities of Van
Kampen American Capital Florida Insured Tax Free Income Fund (the "Fund"),
including the portfolio of investments, as of December 31, 1996, and the related
statement of operations for the year then ended, the statement of changes in net
assets for each of the two years in the period then ended, and the financial
highlights for each of the periods presented. These financial statements and
financial highlights are the responsibility of the Fund's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of
December 31, 1996, by correspondence with the custodian and brokers. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.
 
    In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of Van
Kampen American Capital Florida Insured Tax Free Income Fund as of December 31,
1996, the results of its operations for the year then ended, the changes in its
net assets for each of the two years in the period then ended, and the financial
highlights for each of the periods presented, in conformity with generally
accepted accounting principles.

1. SIGNIFICANT ACCOUNTING POLICIES
 
Van Kampen American Capital Florida Insured Tax Free Income Fund (the "Fund") is
organized as a series of the Van Kampen American Capital Tax Free Trust, a
Delaware business trust, and is registered as a non-diversified open-end
management investment company under the Investment Company Act of 1940, as
amended. The Fund's investment objective is to provide investors a high level of
current income exempt from federal income and Florida state intangibles taxes,
consistent with preservation of capital. Under normal market conditions, the
Fund will invest at least 80% of its assets in insured Florida municipal
securities. The Fund commenced investment operations on July 29, 1994.
 
    The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. The
preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.
 
A.  SECURITY VALUATION--Investments are stated at value using market quotations
or, if such valuations are not available, estimates obtained from yield data
relating to instruments or securities with similar characteristics in accordance
with procedures established in good faith by the Board of Trustees. Short-term
securities with remaining maturities of 60 days or less are valued at amortized
cost.
 
B.  SECURITY TRANSACTIONS--Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis. The
Fund may purchase and sell securities on a "when issued" or "delayed delivery"
basis, with settlement to occur at a later date. The value of the security so
purchased is subject to market fluctuations during this period. The Fund will
maintain, in a segregated account with its custodian, assets having an aggregate
value at least equal to the amount of the when issued or delayed delivery
purchase commitments until payment is made.
 
C.  INVESTMENT INCOME--Interest income is recorded on an accrual basis. Bond
premium and original issue discount on securities purchased are amortized over
the expected life of each applicable security.

                              December 31, 1996
- --------------------------------------------------------------------------------
 
D. ORGANIZATIONAL EXPENSES--The Fund will reimburse Van Kampen American Capital
Distributors, Inc. or its affiliates (collectively "VKAC") for costs incurred in
connection with the Fund's organization in the amount of $120,000. These costs
are being amortized on a straight line basis over the 60 month period ending
July 28, 1999. Van Kampen American Capital Investment Advisory Corp. (the
"Adviser") has agreed that in the event any of the initial shares of the Fund
originally purchased by VKAC are redeemed during the amortization period, the
Fund will be reimbursed for any unamortized organizational expenses in the same
proportion as the number of shares redeemed bears to the number of initial
shares held at the time of redemption.
 
E. FEDERAL INCOME TAXES--It is the Fund's policy to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income, if any, to its shareholders.
Therefore, no provision for federal income taxes is required.
 
F. DISTRIBUTION OF INCOME AND GAINS--The Fund declares daily and pays monthly
dividends from net investment income. Net realized gains, if any, are
distributed annually. For the year ended December 31, 1996, 99.5% of the income
distributions made by the Fund were exempt from federal income taxes. Due to
inherent differences in the recognition of certain expenses under generally
accepted accounting principles and federal income tax purposes, the amount of
distributable net investment income may differ between book and federal income
tax purposes for a particular period. These differences are temporary in nature,
but may result in book basis distribution in excess of net investment income for
certain periods.

2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES
 
Under the terms of the Fund's Investment Advisory Agreement, the Adviser will
provide investment advice and facilities to the Fund for an annual fee payable
monthly as follows:

</TABLE>
 
    Certain legal expenses are paid to Skadden, Arps, Slate, Meagher & Flom
(Illinois), counsel to the Fund, of which a trustee of the Fund is an affiliated
person.
 
    For the year ended December 31, 1996, the Fund incurred expenses of
approximately $16,500 representing VKAC's cost of providing accounting, cash
management and legal services to the Fund. All of these expenses were assumed by
VKAC.
 
    ACCESS Investor Services, Inc. ("ACCESS"), an affiliate of the Adviser,
serves as the shareholder servicing agent of the Fund. For the year ended
December 31, 1996, the Fund incurred expenses of approximately $8,400,
representing ACCESS' cost of providing transfer agency and shareholder services
plus a profit. All of this expense was assumed by VKAC.
 
    Certain officers and trustees of the Fund are also officers and directors of
VKAC. The Fund does not compensate its officers or trustees who are officers of
VKAC. For the year ended December 31, 1996, the Adviser reimbursed the Fund for
certain trustees' compensation in connection with the July 1995 increase in the
number of trustees of the Fund.
 
    The Fund has implemented deferred compensation and retirement plans for its
trustees. Under the deferred compensation plan, trustees may elect to defer all
or a portion of their compensation to a later date. The retirement plan covers
those trustees who are not officers of VKAC.
 
    At December 31, 1996, VKAC owned 100 shares each of Classes A, B and C.
 
3.  CAPITAL TRANSACTIONS
 
The Fund has outstanding three classes of shares of beneficial interest, Classes
A, B and C each with a par value of $.01 per share. There are an unlimited
number of shares of each class authorized.

not represent expenses of the Fund.
 
4. INVESTMENT TRANSACTIONS
 
During the period, the cost of purchases and proceeds from sales of investments,
excluding short-term investments, for the year ended December 31, 1996, were
$33,527,727 and $23,944,324, respectively.
 
5. DERIVATIVE FINANCIAL INSTRUMENTS
 
A derivative financial instrument in very general terms refers to a security
whose value is "derived" from the value of an underlying asset, reference rate
or index.
 
    The Fund has a variety of reasons to use derivative instruments, such as to
attempt to protect the Fund against possible changes in the market value of its
portfolio and to manage the portfolio's effective yield, maturity and duration.
All of the Fund's portfolio holdings, including derivative instruments, are
marked to market each day with the change in value reflected in the unrealized
appreciation/depreciation on securities. Upon disposition, a realized gain or
loss is recognized accordingly, except when exercising an option contract or
taking delivery of a security underlying a futures contract. In these instances,
the recognition of gain or loss is postponed until the disposal of the security
underlying the option or futures contract.
 
    Summarized below are the specific types of derivative financial instruments
used by the Fund.

- --------------------------------------------------------------------------------
 
A. OPTION CONTRACTS--An option contract gives the buyer the right, but not the
obligation to buy (call) or sell (put) an underlying item at a fixed exercise
price during a specified period. These contracts are generally used by the Fund
to manage the portfolio's effective maturity and duration.
 
    Transactions in options for the year ended December 31, 1996, were as
follows:

B. FUTURES CONTRACTS--A futures contract is an agreement involving the delivery
of a particular asset on a specified future date at an agreed upon price. The
Fund generally invests in futures on U.S. Treasury Bonds and the Municipal Bond
Index and typically closes the contract prior to the delivery date.
 
    Upon entering into futures contracts, the Fund maintains, in a segregated
account with its custodian, securities with a value equal to its obligation
under the futures contracts. During the period the futures contract is open,
payments are received from or made to the broker based upon changes in the value
of the contract (the variation margin).
 
    Transactions in futures contracts, each with a par value of $100,000, for
the year ended December 31, 1996, were as follows:

6. DISTRIBUTION AND SERVICE PLANS
 
The Fund and its shareholders have adopted a distribution plan pursuant to Rule
12b-1 under the Investment Company Act of 1940 and a service plan (collectively
the "Plans"). The Plans govern payments for the distribution of the Fund's
shares, ongoing shareholder services and maintenance of shareholder accounts.
 
    Annual fees under the Plans of up to .25% of Class A net assets and 1.00%
each of Class B and Class C net assets are accrued daily. Included in these fees
for the year ended December 31, 1996, are payments to VKAC of approximately
$130,400.

                      STATEMENT OF ADDITIONAL INFORMATION
 
          VAN KAMPEN AMERICAN CAPITAL NEW JERSEY TAX FREE INCOME FUND
 
  Van Kampen American Capital New Jersey Tax Free Income Fund, formerly known as
Van Kampen Merritt New Jersey Tax Free Income Fund (the "Fund"), seeks to
provide investors with high current income exempt from federal income tax and
New Jersey gross income tax, consistent with preservation of capital. The Fund
is designed for investors who are residents of New Jersey for tax purposes.
Under normal market conditions, the Fund attempts to achieve its investment
objective by investing at least 80% of its assets in a portfolio of New Jersey
municipal securities rated investment grade at the time of investment.
Investment grade securities are securities rated BBB or higher by Standard &
Poors Ratings Group ("S&P"), Baa or higher by Moody's Investors Service, Inc.
("Moody's") or an equivalent rating by another nationally recognized statistical
rating organization ("NRSRO"). Up to 20% of the Fund's total assets may consist
of New Jersey municipal securities rated below investment grade (but not rated
lower than B- by S&P, B3 by Moody's or an equivalent rating by another NRSRO)
and unrated New Jersey municipal securities believed by the Fund's investment
adviser to be of comparable quality, which involve special risk considerations.
There is no assurance that the Fund will achieve its investment objective. The
Fund is a separate series of Van Kampen American Capital Tax Free Trust, a
Delaware business trust (the "Trust").

                             THE FUND AND THE TRUST
 
   
  Van Kampen American Capital New Jersey Tax Free Income Fund (the "Fund") is a
separate series of the Trust, an open-end non-diversified management investment
company. At present, the Fund, Van Kampen American Capital Insured Tax Free
Income Fund, Van Kampen American Capital Tax Free High Income Fund, Van Kampen
American Capital Municipal Income Fund, Van Kampen American Capital Intermediate
Term Municipal Income Fund, Van Kampen American Capital California Insured Tax
Free Fund, Van Kampen American Capital New York Tax Free Income Fund and Van
Kampen American Capital Florida Insured Tax Free Income Fund have been organized
as series of the Trust and have commenced investment operations. Van Kampen
American Capital California Tax Free Income Fund, Van Kampen American Capital
Michigan Tax Free Income Fund, Van Kampen American Capital Missouri Tax Free
Income Fund and Van Kampen American Capital Ohio Tax Free Income Fund have been
organized as series of the Trust but have not commenced investment operations.
Other series may be organized and offered in the future.
    
 
  The Trust is an unincorporated business trust established under the laws of
the State of Delaware by an Agreement and Declaration of Trust (the "Declaration
of Trust") dated as of May 10, 1995. The Declaration of Trust permits the
Trustees to create one or more separate investment portfolios and issue a series
of shares for each portfolio. The Trustees can further sub-divide each series of
shares into one or more classes of shares for each portfolio. The Trust can
issue an unlimited number of shares, $0.01 par value (prior to July 31, 1995,
the shares had no par value). Each share represents an equal proportionate
interest in the assets of the series with each other share in such series and no
interest in any other series. No series is subject to the liabilities of any
other series. The Declaration of Trust provides that shareholders are not liable
for any liabilities of the Trust or any of its series, requires inclusion of a
clause to that effect in every agreement entered into by the Trust or any of its
series and indemnifies shareholders against any such liability. The Fund was
originally organized in 1994 under the name Van Kampen Merritt New Jersey Tax
Free Income Fund as a sub-trust of Van Kampen Merritt Tax Free Fund, a
Massachusetts business trust. The Fund was reorganized as a series of the Trust
and adopted its present name as of July 31, 1995.
 
  Shares of the Trust entitle their holders to one vote per share; however,
separate votes are taken by each series on matters affecting an individual
series. For example, a change in investment policy for a series would be voted
upon by shareholders of only the series involved. Except as described in the
Prospectus, shares do not have cumulative voting rights, preemptive rights or
any conversion or exchange rights. The Trust does not contemplate holding
regular meetings of shareholders to elect Trustees or otherwise. However, the
holders of 10% or more of the outstanding shares may by written request require
a meeting to consider the removal of Trustees by a vote of two-thirds of the
shares then outstanding cast in person or by proxy at such meeting.
 
  The Trustees may amend the Declaration of Trust (including with respect to any
series) in any manner without shareholder approval, except that the Trustees may
not adopt any amendment adversely affecting the rights of shareholders of any
series without approval by a majority of the shares of each affected series
present at a meeting of shareholders (or such higher vote as may be required by
the Investment Company Act of 1940, as amended (the "1940 Act") or other
applicable law) and except that the Trustees cannot amend the Declaration of
Trust to impose any liability on shareholders, make any assessment on shares or
impose liabilities on the Trustees without approval from each affected
shareholder or Trustee, as the case may be.
 
  Statements contained in this Statement of Additional Information as to the
contents of any contract or other document referred to are not necessarily
complete, and, in each instance, reference is made to the copy of such contract
or other document filed as an exhibit to the Registration Statement of which
this Statement of Additional Information forms a part, each such statement being
qualified in all respects by such reference.
 
                      INVESTMENT POLICIES AND RESTRICTIONS
 
  The investment objective of the Fund is set forth in the Prospectus under the
caption "Investment Objective and Policies." There can be no assurance that the
Fund will achieve its investment objective.
 
  Fundamental investment restrictions limiting the investments of the Fund
provide that the Fund may not:
 
   1. Invest more than 25% of its assets in a single industry; however, as
      described in the Prospectus, the Fund may from time to time invest more
      than 25% of its assets in a particular segment of the municipal
 
                                       B-2
<PAGE>   749
 
   
      bond market; however, the Fund will not invest more than 25% of its assets
      in industrial development bonds in a single industry, except that the Fund
      may purchase securities of other investment companies to the extent
      permitted by (i) the 1940 Act, as amended from time to time, (ii) the
      rules and regulations promulgated by the SEC under the 1940 Act, as
      amended from time to time, or (iii) an exemption or other relief from the
      provisions of the 1940 Act.
    
 
   2. Borrow money, except from banks for temporary purposes and then in amounts
      not in excess of 5% of the total asset value of the Fund, or mortgage,
      pledge, or hypothecate any assets except in connection with a borrowing
      and in amounts not in excess of 10% of the total asset value of the Fund.
      Borrowings may not be made for investment leverage, but only to enable the
      Fund to satisfy redemption requests where liquidation of portfolio
      securities is considered disadvantageous or inconvenient. In this
      connection, the Fund will not purchase portfolio securities during any
      period that such borrowings exceed 5% of the total asset value of the
      Fund. Notwithstanding this investment restriction, the Fund may enter into
      when issued and delayed delivery transactions as described in the
      Prospectus.
 
   3. Make loans of money or property to any person, except to the extent the
      securities in which the Fund may invest are considered to be loans and
      except that the Fund may lend money or property in connection with
      maintenance of the value of, or the Fund's interest with respect to, the
      securities owned by the Fund.
 
   4. Buy any securities "on margin." Neither the deposit of initial or
      maintenance margin in connection with hedging transactions nor short term
      credits as may be necessary for the clearance of transactions is
      considered the purchase of a security on margin.
 
   5. Sell any securities "short," write, purchase or sell puts, calls or
      combinations thereof, or purchase or sell interest rate or other financial
      futures or index contracts or related options, except in connection with
      Strategic Transactions in accordance with the requirements of the SEC and
      the Commodity Futures Trading Commission.
 
   6. Act as an underwriter of securities, except to the extent the Fund may be
      deemed to be an underwriter in connection with the sale of securities held
      in its portfolio.
 
   
   7. Make investments for the purpose of exercising control or participation in
      management, except to the extent that exercise by the Fund of its rights
      under agreements related to securities owned by the Fund would be deemed
      to constitute such control or participation, except that the Fund may
      purchase securities of other investment companies to the extent permitted
      by (i) the 1940 Act, as amended from time to time, (ii) the rules and
      regulations promulgated by the SEC under the 1940 Act, as amended from
      time to time, or (iii) an exemption or other relief from the provisions of
      the 1940 Act.
    
 
   
   8. Invest in securities issued by other investment companies except as part
      of a merger, reorganization or other acquisition and extent permitted by
      (i) the 1940 Act, as amended from time to time, (ii) the rules and
      regulations promulgated by the SEC under the 1940 Act, as amended from
      time to time, or (iii) an exemption or other relief from the provisions of
      the 1940 Act.
    
 
   9. Invest in oil, gas or mineral leases or in equity interests in oil, gas,
      or other mineral exploration or development programs, except pursuant to
      the exercise by the Fund of its rights under agreements relating to
      municipal securities.
 
  10. Purchase or sell real estate, commodities or commodity contracts, except
      to the extent the securities the Fund may invest in are considered to be
      interest in real estate, commodities or commodity contracts or to the
      extent the Fund exercises its rights under agreements relating to such
      securities (in which case the Fund may own, hold, foreclose, liquidate or
      otherwise dispose of real estate acquired as a result of a default on a
      mortgage), and except to the extent that Strategic Transactions the Fund
      may engage in are considered to be commodities or commodities contracts.
 
  The Fund may not change any of these investment restrictions nor any other
fundamental policy as they apply to the Fund without the approval of the lesser
of (i) more than 50% of the Fund's outstanding shares or
 
                                       B-3
<PAGE>   750
 
(ii) 67% of the Fund's shares present at a meeting at which the holders of more
than 50% of the outstanding shares are present in person or by proxy. As long as
the percentage restrictions described above are satisfied at the time of the
investment or borrowing, the Fund will be considered to have abided by those
restrictions even if, at a later time, a change in values or net assets causes
an increase or decrease in percentage beyond that allowed.
 
  These investment restrictions are subject to provisions of applicable New
Jersey tax law. Thus, under current New Jersey tax law, the Fund must not hold
any investments in real estate or commodities to qualify as a "qualified
investment fund". See the Prospectus under the caption "Tax Status -- New Jersey
Taxation."
 
  The Fund generally will not engage in the trading of securities for the
purpose of realizing short-term profits, but it will adjust its portfolio as
deemed advisable in view of prevailing or anticipated market conditions to
accomplish the Fund's investment objectives. For example, the Fund may sell
portfolio securities in anticipation of a movement in interest rates. Frequency
of portfolio turnover will not be a limiting factor if the Fund considers it
advantageous to purchase or sell securities. Portfolio turnover is calculated by
dividing the lesser of purchases or sales of portfolio securities by the monthly
average value of the securities in the portfolio during the year. Securities,
including options, whose maturity or expiration date at the time of acquisition
were one year or less are excluded from such calculation. The Fund anticipates
that its annual portfolio turnover rate will normally be less than 200%.
 
                      ADDITIONAL INVESTMENT CONSIDERATIONS
 
MUNICIPAL SECURITIES
 
  Municipal securities include long-term obligations, which are often called
municipal bonds, as well as shorter term municipal notes, municipal leases, and
tax exempt commercial paper. Under normal market conditions, longer term
municipal securities generally provide a higher yield than shorter term
municipal securities, and therefore the Fund generally expects to be invested
primarily in longer term municipal securities. The Fund will, however, invest in
shorter term municipal securities when yields are greater than yields available
on longer term municipal securities, for temporary defensive purposes and when
redemption requests are expected. The two principal classifications of municipal
bonds are "general obligation" and "revenue" or "special obligation" bonds,
which include "industrial revenue bonds." General obligation bonds are secured
by the issuer's pledge of its faith, credit, and taxing power for the payment of
principal and interest. Revenue or special obligation bonds are payable only
from the revenues derived from a particular facility or class of facilities or,
in some cases, from the proceeds of a special tax or other specific revenue
source such as from the user of the facility being financed.
 
  Also included within the general category of municipal securities are
participations in lease obligations or installment purchase contract obligations
(hereinafter collectively called "lease obligations") of municipal authorities
of entities used to finance the acquisition of equipment and facilities.
Although lease obligations do not constitute general obligations of the
municipality for which the municipality's taxing power is pledged, a lease
obligation is ordinarily backed by the municipality's covenant to budget for,
appropriate and make the payments due under the lease obligation. However,
certain lease obligations contain "non-appropriation" clauses which provide that
the municipality has no obligation to make lease or installment purchase
payments in future years unless money is appropriated for such purpose on a
yearly basis. A risk exists that the municipality will not, or will be unable
to, appropriate money in the future in the event of political changes, changes
in the economic viability of the project, general economic changes or for other
reasons. In addition to the "non-appropriation" risk, these securities represent
a relatively new type of financing that has not yet developed the depth of
marketability associated with more conventional bonds. Although
"non-appropriation" lease obligations are often secured by an assignment of the
lessee's interest in the leased property, management and/or disposition of the
property in the event of foreclosure could be costly, time consuming and result
in unsatisfactory recoupment of the Fund's original investment and would
adversely affect the Fund's status as a "qualified investment fund" under New
Jersey tax law. There is no limitation on the percentage of the Fund's assets
that may be invested in "non-appropriation" lease obligations. In evaluating
such lease obligations, the Adviser will consider such factors as it deems
appropriate, which factors may
 
                                       B-4
<PAGE>   751
 
include (a) whether the lease can be cancelled, (b) the ability of the lease
obligee to direct the sale of the underlying assets, (c) the general
creditworthiness of the lease obligor, (d) the likelihood that the municipality
will discontinue appropriating funding for the leased property in the event such
property is no longer considered essential by the municipality, (e) the legal
recourse of the lease obligee in the event of such a failure to appropriate
funding and (f) any limitations which are imposed on the lease obligor's ability
to utilize substitute property or services than those covered by the lease
obligation. The Fund will invest in lease obligations which contain
non-appropriation clauses only if such obligations are rated investment grade,
at the time of investment.
 
  Also included in the term municipal securities are participation certificates
issued by state and local governments or authorities to finance the acquisition
of equipment and facilities. They may represent participations in a lease, an
installment purchase contract, or a conditional sales contract.
 
  The Fund may purchase floating and variable rate demand notes, which are
municipal securities normally having a stated maturity in excess of one year,
but which permit the holder to demand payment of principal at any time, or at
specified intervals. The issuer of such notes normally has a corresponding
right, after a given period, to prepay at its discretion upon notice to the
noteholders the outstanding principal amount of the notes plus accrued interest.
The interest rate on a floating rate demand note is based on a known lending
rate, such as a bank's prime rate, and is adjusted automatically each time such
rate is adjusted. The interest rate on a variable rate demand note is adjusted
automatically at specified intervals.
 
  The Fund also may invest up to 20% of its total assets in variable rate
derivative municipal securities such as inverse floaters whose rates vary
inversely with changes in market rates of interest. When market rates of
interest decrease, the change in value of such securities will have a positive
effect on the net asset value of the Fund, and when market rates of interest
increase, the change in value of such securities will have a negative effect on
the net asset value of the Fund. Inverse floaters may pay a rate of interest
determined by applying a multiple to the variable rate. The extent of increases
and decreases in the value of inverse floaters in response to changes in market
rates of interest generally will be larger than comparable changes in the value
of an equal principal amount of a fixed rate municipal security having similar
credit quality, redemption provisions and maturity.
 
  The Fund may also acquire custodial receipts or certificates underwritten by
securities dealers or banks that evidence ownership of future interest payments,
principal payments or both on certain municipal securities. The underwriter of
these certificates or receipts typically purchases municipal securities and
deposits the securities in an irrevocable trust or custodial account with a
custodian bank, which then issues receipts or certificates that evidence
ownership of the periodic unmatured coupon payments and the final principal
payment on the obligations. Although under the terms of a custodial receipt, the
Fund typically would be authorized to assert its rights directly against the
issuer of the underlying obligation, the Fund could be required to assert
through the custodian bank those rights as may exist against the underlying
issuer. Thus, in the event the underlying issuer fails to pay principal or
interest when due, the Fund may be subject to delays, expenses and risks that
are greater than those that would have been involved if the Fund had purchased a
direct obligation of the issuer. In addition, in the event that the trust or
custodial account in which the underlying security has been deposited is
determined to be an association taxable as a corporation, instead of a
non-taxable entity, the yield on the underlying security would be reduced in
recognition of any taxes paid and would adversely affect the Fund's status as a
"qualified investment fund" under New Jersey tax law.
 
  The "issuer" of municipal securities generally is deemed to be the
governmental agency, authority, instrumentality or other political subdivision,
or the non-governmental user of a revenue bond-financed facility, the assets and
revenues of which will be used to meet the payment obligations, or the guarantee
of such payment obligations, of the municipal securities.
 
  Although the Fund will invest at least 80% of its assets in municipal
securities rated investment grade at the time of investment, municipal
securities, like other debt obligations, are subject to the risk of non-payment.
The ability of issuers of municipal securities to make timely payments of
interest and principal may be adversely impacted in general economic downturns
and as relative governmental cost burdens are allocated and reallocated among
federal, state and local governmental units. Such non-payment would result in a
reduction of income to the Fund, and could result in a reduction in the value of
the municipal security
 
                                       B-5
<PAGE>   752
 
experiencing non-payment and a potential decrease in the net asset value of the
Fund. Issuers of municipal securities might seek protection under the bankruptcy
laws. In the event of bankruptcy of such an issuer, the Fund could experience
delays and limitations with respect to the collection of principal and interest
on such municipal securities and the Fund may not, in all circumstances, be able
to collect all principal and interest to which it is entitled. To enforce its
rights in the event of a default in the payment of interest or repayment of
principal, or both, the Fund may take possession of and manage the assets
securing the issuer's obligations on such securities, which may increase the
Fund's operating expenses and adversely affect the net asset value of the Fund
and would adversely affect the Fund's status as a "qualified investment fund"
under New Jersey tax law. Any income derived from the Fund's ownership or
operation of such assets may not be tax-exempt. In addition, the Fund's
intention to qualify as a "regulated investment company" under the Internal
Revenue Code of 1986, as amended (the "Code"), may limit the extent to which the
Fund may exercise its rights by taking possession of such assets, because as a
regulated investment company the Fund is subject to certain limitations on its
investments and on the nature of its income. Further, in connection with the
working out or restructuring of a defaulted security, the Fund may acquire
additional securities of the issuer, the acquisition of which may be deemed to
be a loan of money or property. Such additional securities should be considered
speculative with respect to the capacity to pay interest or repay principal in
accordance with their terms.
 
  The Fund may invest up to 15% of its total assets in illiquid securities,
securities the disposition of which is subject to substantial legal or
contractual restrictions on resale and securities that are not readily
marketable. The sale of restricted and illiquid securities often requires more
time and results in higher brokerage charges or dealer discounts and other
selling expenses than does the sale of securities eligible for trading on
national securities exchanges or in the over-the-counter markets. Restricted
securities may sell at a price lower than similar securities that are not
subject to restrictions on resale. Restricted securities salable among qualified
institutional buyers without restriction pursuant to Rule 144A under the
Securities Act of 1933, as amended, that are determined to be liquid by the
Adviser under guidelines adopted by the Board of Trustees of the Trust (under
which guidelines the Adviser will consider factors such as trading activities
and the availability of price quotations), will not be treated as restricted
securities by the Fund pursuant to such rules. The Fund may, from time to time,
adopt a more restrictive limitation with respect to investment in illiquid and
restricted securities in order to comply with the most restrictive state
securities law, currently 10%. This policy does not include restricted
securities eligible for resale pursuant to Rule 144A under the Securities Act of
1933, as amended, which the Board of Trustees or the Fund's investment adviser
has determined under Board-approved guidelines to be liquid. The Fund's policy
with respect to investment in illiquid and restricted securities is not a
fundamental policy and may be changed by the Board of Trustees, in consultation
with the Adviser, without obtaining shareholder approval.
 
LOWER GRADE MUNICIPAL SECURITIES
 
  In normal circumstances, at least 80% of the Fund's total assets will be
invested in investment grade municipal securities and up to 20% of the Fund's
total assets may be invested in lower grade municipal securities. The amount of
available information about the financial condition of municipal securities
issuers is generally less extensive than that for corporate issuers with
publicly traded securities and the market for municipal securities is considered
to be generally less liquid than the market for corporate debt obligations.
Liquidity relates to the ability of a Fund to sell a security in a timely manner
at a price which reflects the value of that security. As discussed below, the
market for lower grade municipal securities is considered generally to be less
liquid than the market for investment grade municipal securities. Further,
municipal securities in which the Fund may invest include special obligation
bonds, lease obligations, participation certificates and variable rate
instruments. The market for such securities may be particularly less liquid. The
relative illiquidity of some of the Fund's portfolio securities may adversely
affect the ability of the Fund to dispose of such securities in a timely manner
and at a price which reflects the value of such security in the Adviser's
judgment. Although the issuer of some such municipal securities may be obligated
to redeem such securities at face value, such redemption could result in capital
losses to the Fund to the extent that such municipal securities were purchased
by the Fund at a premium to face value. The market for less liquid securities
tends to be more volatile than the market for more liquid securities and market
values of relatively illiquid securities may be more susceptible to change as a
result of adverse publicity and investor perceptions than are the market values
of higher grade, more liquid securities.
 
                                       B-6
<PAGE>   753
 
  The Fund's net asset value will change with changes in the value of its
portfolio securities. Because the Fund will invest primarily in fixed income
municipal securities, the Fund's net asset value can be expected to change as
general levels of interest rates fluctuate. When interest rates decline, the
value of a portfolio invested in fixed income securities can be expected to
rise. Conversely, when interest rates rise, the value of a portfolio invested in
fixed income securities can be expected to decline. Net asset value and market
value may be volatile due to the Fund's investment in lower grade and less
liquid municipal securities. Volatility may be greater during periods of general
economic uncertainty.
 
  The Adviser values the Fund's investments pursuant to guidelines adopted and
periodically reviewed by the Board of Trustees. To the extent that there is no
established retail market for some of the securities in which the Fund may
invest, there may be relatively inactive trading in such securities and the
ability of the Adviser to accurately value such securities may be adversely
affected. During periods of reduced market liquidity and in the absence of
readily available market quotations for securities held in the Fund's portfolio,
the responsibility of the Adviser to value the Fund's securities becomes more
difficult and the Adviser's judgment may play a greater role in the valuation of
the Fund's securities due to the reduced availability of reliable objective
data. To the extent that the Fund invests in illiquid securities and securities
which are restricted as to resale, the Fund may incur additional risks and
costs. Illiquid and restricted securities are particularly difficult to dispose
of.
 
  Lower grade municipal securities generally involve greater credit risk than
higher grade municipal securities. A general economic downturn or a significant
increase in interest rates could severely disrupt the market for lower grade
municipal securities and adversely affect the market value of such securities.
In addition, in such circumstances, the ability of issuers of lower grade
municipal securities to repay principal and to pay interest, to meet projected
financial goals and to obtain additional financing may be adversely affected.
Such consequences could lead to an increased incidence of default for such
securities and adversely affect the value of the lower grade municipal
securities in the Fund's portfolio and thus the Fund's net asset value. The
secondary market prices of lower grade municipal securities are less sensitive
to changes in interest rates than are those for higher rated municipal
securities, but are more sensitive to adverse economic changes or individual
issuer developments. Adverse publicity and investor perceptions, whether or not
based on rational analysis, may also affect the value and liquidity of lower
grade municipal securities.
 
  Yields on the Fund's portfolio securities can be expected to fluctuate over
time. In addition, periods of economic uncertainty and changes in interest rates
can be expected to result in increased volatility of the market prices of the
lower grade municipal securities in the Fund's portfolio and thus in the net
asset value of the Fund. Net asset value and market value may be volatile due to
the Fund's investment in lower grade and less liquid municipal securities.
Volatility may be greater during periods of general economic uncertainty. The
Fund may incur additional expenses to the extent it is required to seek recovery
upon a default in the payment of interest or a repayment of principal on its
portfolio holdings, and the Fund may be unable to obtain full recovery thereof.
In the event that an issuer of securities held by the Fund experiences
difficulties in the timely payment of principal or interest and such issuer
seeks to restructure the terms of its borrowings, the Fund may incur additional
expenses and may determine to invest additional capital with respect to such
issuer or the project or projects to which the Fund's portfolio securities
relate. Recent and proposed legislation may have an adverse impact on the market
for lower grade municipal securities. Recent legislation requires federally-
insured savings and loan associations to divest their investments in lower grade
bonds. Other legislation has been proposed which, if enacted, could have an
adverse impact on the market for lower grade municipal securities.
 
  The Fund will rely on the Adviser's judgment, analysis and experience in
evaluating the creditworthiness of an issue. In this evaluation, the Adviser
will take into consideration, among other things, the issuer's financial
resources, its sensitivity to economic conditions and trends, its operating
history, the quality of the issuer's management and regulatory matters. The
Adviser also may consider, although it does not rely primarily on, the credit
ratings of S&P, Moody's or another NRSRO in evaluating municipal securities.
Such ratings evaluate only the safety of principal and interest payments, not
market value risk. Additionally, because the creditworthiness of an issuer may
change more rapidly than is able to be timely reflected in changes in credit
ratings, the Adviser continuously monitors the issuers of municipal securities
held in the Fund's portfolio. The Fund may, if deemed appropriate by the
Adviser, retain a security whose rating has been downgraded below
 
                                       B-7
<PAGE>   754
 
B- by S&P, below B3 by Moody's or an equivalent rating by another NRSRO, or
whose rating has been withdrawn.
 
  Because issuers of lower grade municipal securities frequently choose not to
seek a rating of their municipal securities, the Adviser will be required to
determine the relative investment quality of many of the municipal securities in
the Fund's portfolio. Further, because the Fund may invest up to 20% of its
total assets in these lower grade municipal securities, achievement by the Fund
of its investment objective may be more dependent upon the Adviser's investment
analysis than would be the case if the Fund were investing exclusively in higher
grade municipal securities. The relative lack of financial information available
with respect to issuers of municipal securities may adversely affect the
Adviser's ability to successfully conduct the required investment analysis.
 
SPECIAL CONSIDERATIONS RELATING TO NEW JERSEY MUNICIPAL SECURITIES
 
  Investors should be aware of certain factors that might affect the financial
condition of issuers of New Jersey municipal securities. New Jersey's economic
base is diversified, consisting of a variety of manufacturing, construction and
service industries, supplemented by rural areas with selective commercial
agriculture. By the beginning of the national recession in 1990, construction
activity had already been declining in New Jersey for nearly two years. The
onset of recession caused an acceleration of New Jersey's job losses in
construction and manufacturing, as well as an employment downturn in such
previously growing sectors as wholesale trade, retail trade, finance, utilities
and trucking and warehousing. Reflecting the downturn, the rate of unemployment
in the State rose from a peacetime low of 3.6% during the first quarter of 1989
to a recessionary peak of 8.4% during 1992. Since then, the unemployment rate
fell to an average of 6.4% during the first ten months of 1995.
 
  More detailed information concerning New Jersey municipal securities and the
State of New Jersey is included in Appendix A of the Statement of Additional
Information.
 
STRATEGIC TRANSACTIONS
 
  The Fund may, but is not required to, utilize various other investment
strategies as described below to hedge various market risks (such as interest
rates and broad or specific market movements) or to manage the effective
maturity or duration of the Fund's fixed-income securities. Such strategies are
generally accepted by modern portfolio managers and are regularly utilized by
many mutual funds and other institutional investors. Techniques and instruments
may change over time as new instruments and strategies are developed or
regulatory changes occur. Under current New Jersey tax law, the Fund may not
hold any investments other than interest-bearing obligations, obligations issued
at a discount and cash and cash items, including receivables and financial
options, futures, forward contracts or other similar financial instruments
related to interest-bearing obligations, obligations issued at a discount or
bond indexes related thereto. See the Prospectus under the caption "Tax Status
- -- New Jersey Taxation."
 
  In the course of pursuing these investment strategies, the Fund may purchase
and sell derivative instruments such as exchange-listed and over-the-counter put
and call options on securities, fixed-income indices and other financial
instruments, purchase and sell financial futures contracts and options thereon,
enter into various interest rate transactions such as swaps, caps, floors or
collars (collectively, all the above are called "Strategic Transactions"). Under
current New Jersey tax law, the Fund may purchase and sell exchange-listed and
over-the-counter put and call options and purchase and sell financial futures.
See the Prospectus under the caption "Tax Status -- New Jersey Taxation." The
Fund also reserves the right to engage in swaps, caps, floors or collars.
However, current New Jersey tax law may limit the Fund's ability to engage in
such transactions. Strategic Transactions may be used to attempt to protect
against possible changes in the market value of securities held in or to be
purchased for the Fund's portfolio resulting from securities markets
fluctuations, to protect the Fund's unrealized gains in the value of its
portfolio securities, to facilitate the sale of such securities for investment
purposes, to manage the effective maturity or duration of the Fund's portfolio,
or to establish a position in the derivatives markets as a temporary substitute
for purchasing or selling particular securities.
 
                                       B-8
<PAGE>   755
 
  Any or all of these investment techniques may be used at any time and there is
no particular strategy that dictates the use of one technique rather than
another, as use of any Strategic Transaction is a function of numerous variables
including market conditions. The ability of the Fund to utilize these Strategic
Transactions successfully will depend on the Adviser's ability to predict
pertinent market movements, which cannot be assured. The Fund will comply with
applicable regulatory requirements when implementing these strategies,
techniques and instruments. Strategic Transactions involving financial futures
and options thereon will be purchased, sold or entered into only for bona fide
hedging, risk management or portfolio management purposes and not for
speculative purposes.
 
  Strategic Transactions have risks associated with them including possible
default by the other party to the transaction, illiquidity and, to the extent
the Adviser's view as to certain market movements is incorrect, the risk that
the use of such Strategic Transactions could result in losses greater than if
they had not been used. Use of put and call options may result in losses to the
Fund, force the sale or purchase of portfolio securities at inopportune times or
for prices other than current market values, limit the amount of appreciation
the Fund can realize on its investments or cause the Fund to hold a security it
might otherwise sell. The use of options and futures transactions entails
certain other risks. In particular, the variable degree of correlation between
price movements of futures contracts and price movements in the related
portfolio position of the Fund creates the possibility that losses on the
hedging instrument may be greater than gains in the value of the Fund's
position. In addition, futures and options markets may not be liquid in all
circumstances and certain over-the-counter options may have no markets. As a
result, in certain markets, the Fund might not be able to close out a
transaction without incurring substantial losses, if at all. Although the use of
futures and options transactions for hedging should tend to minimize the risk of
loss due to a decline in the value of the hedged position, at the same time they
tend to limit any potential gain which might result from an increase in value of
such position. Finally, the daily variation margin requirements for futures
contracts would create a greater ongoing potential financial risk than would
purchases of options, where the exposure is limited to the cost of the initial
premium. Losses resulting from the use of Strategic Transactions would reduce
net asset value, and possibly income, and such losses can be greater than if the
Strategic Transactions had not been utilized. Income earned or deemed to be
earned, if any, by the Fund from its Strategic Transactions will generally be
taxable income of the Fund. See "Tax Status" in the Prospectus.
 
  GENERAL CHARACTERISTICS OF OPTIONS.   Put options and call options typically
have similar structural characteristics and operational mechanics regardless of
the underlying instrument on which they are purchased or sold. Thus, the
following general discussion relates to each of the particular types of options
discussed in greater detail below. In addition, many Strategic Transactions
involving options require segregation of Fund assets in special accounts, as
described below under "Use of Segregated and Other Special Accounts."
 
  A put option gives the purchaser of the option, upon payment of a premium, the
right to sell, and the writer the obligation to buy, the underlying security,
commodity, index, or other instrument at the exercise price. For instance, the
Fund's purchase of a put option on a security might be designed to protect its
holdings in the underlying instrument (or, in some cases, a similar instrument)
against a substantial decline in the market value by giving the Fund the right
to sell such instrument at the option exercise price. A call option, upon
payment of a premium, gives the purchaser of the option the right to buy, and
the seller the obligation to sell, the underlying instrument at the exercise
price. The Fund's purchase of a call option on a security, financial future,
index, or other instrument might be intended to protect the Fund against an
increase in the price of the underlying instrument that it intends to purchase
in the future by fixing the price at which it may purchase such instrument. An
American style put or call option may be exercised at any time during the option
period while a European style put or call option may be exercised only upon
expiration or during a fixed period prior thereto. The Fund is authorized to
purchase and sell exchange listed options and over-the-counter options ("OTC
options"). Exchange listed options are issued by a regulated intermediary such
as the Options Clearing Corporation ("OCC"), which guarantees the performance of
the obligations of the parties to such options. The discussion below uses the
OCC as a paradigm, but is also applicable to other financial intermediaries.
 
  With certain exceptions, OCC issued and exchange listed options generally
settle by physical delivery of the underlying security or currency, although in
the future cash settlement may become available. Index options
 
                                       B-9
<PAGE>   756
 
and Eurodollar instruments are cash settled for the net amount, if any, by which
the option is "in-the-money" (i.e., where the value of the underlying instrument
exceeds, in the case of a call option, or is less than, in the case of a put
option, the exercise price of the option) at the time the option is exercised.
Frequently, rather than taking or making delivery of the underlying instrument
through the process of exercising the option, listed options are closed by
entering into offsetting purchase or sale transactions that do not result in
ownership of the new option.
 
  The Fund's ability to close out its position as a purchaser or seller of an
OCC or exchange listed put or call option is dependent, in part, upon the
liquidity of the option market. Among the possible reasons for the absence of a
liquid option 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 including
reaching daily price limits; (iv) interruption of the normal operations of the
OCC or an exchange; (v) inadequacy of the facilities of an exchange or 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 relevant market for that option on that exchange would cease
to exist, although outstanding options on that exchange would generally continue
to be exercisable in accordance with their terms.
 
  The hours of trading for listed options may not coincide with the hours during
which the underlying financial instruments are traded. To the extent that the
option markets close before the markets for the underlying financial
instruments, significant price and rate movements can take place in the
underlying markets that cannot be reflected in the option markets.
 
  OTC options are purchased from or sold to securities dealers, financial
institutions or other parties ("Counterparties") through direct bilateral
agreement with the Counterparty. In contrast to exchange listed options, which
generally have standardized terms and performance mechanics, all the terms of an
OTC option, including such terms as method of settlement, term, exercise price,
premium, guarantees and security, are set by negotiation of the parties. The
Fund will only sell OTC options that are subject to a buy-back provision
permitting the Fund to require the Counterparty to sell the option back to the
Fund at a formula price within seven days. The Fund expects generally to enter
into OTC options that have cash settlement provisions, although it is not
required to do so.
 
  Unless the parties provide for it, there is no central clearing or guaranty
function in an OTC option. As a result, if the Counterparty fails to make or
take delivery of the security, or other instrument underlying an OTC option it
has entered into with the Fund or fails to make a cash settlement payment due in
accordance with the terms of that option, the Fund will lose any premium it paid
for the option as well as any anticipated benefit of the transaction.
Accordingly, the Adviser must assess the creditworthiness of each such
Counterparty or any guarantor or credit enhancement of the Counterparty's credit
to determine the likelihood that the terms of the OTC option will be satisfied.
The Fund will engage in OTC option transactions only with United States
government securities dealers recognized by the Federal Reserve Bank of New York
as "primary dealers", or broker dealers, domestic or foreign banks or other
financial institutions which have received (or the guarantors of the obligation
of which have received) a short-term credit rating of "A-1" from S&P or "P-1"
from Moody's or an equivalent rating from any other NRSRO. The staff of the SEC
currently takes the position that, in general, OTC options on securities other
than U.S. Government securities purchased by the Fund, and portfolio securities
"covering" the amount of the Fund's obligation pursuant to an OTC option sold by
it (the cost of the sell-back plus the in-the-money amount, if any) are
illiquid, and are subject to the Fund's limitation on investing no more than 15%
of its assets in illiquid securities.
 
  If the Fund sells a call option, the premium that it receives may serve as a
partial hedge, to the extent of the option premium, against a decrease in the
value of the underlying securities or instruments in its portfolio or will
increase the Fund's income. The sale of put options can also provide income.
 
  The Fund may purchase and sell call options on securities, including U.S.
Treasury and agency securities, municipal obligations, mortgage-backed
securities and Eurodollar instruments that are traded on U.S. and foreign
securities exchanges and in the over-the-counter markets. All calls sold by the
Fund must be "covered" (i.e., the Fund must own the securities or futures
contract subject to the call) or must meet the asset segregation requirements
described below as long as the call is outstanding. Even though the Fund will
 
                                      B-10
<PAGE>   757
 
receive the option premium to help protect it against loss, a call sold by the
Fund exposes the Fund during the term of the option to possible loss of
opportunity to realize appreciation in the market price of the underlying
security or instrument and may require the Fund to hold a security or instrument
which it might otherwise have sold. In the event of exercise of a call option
sold by the Fund with respect to securities not owned by the Fund, the Fund may
be required to acquire the underlying security at a disadvantageous price in
order to satisfy its obligation with respect to the call option.
 
  The Fund may purchase and sell put options on securities including U.S.
Treasury and agency securities, mortgage-backed securities, municipal
obligations and Eurodollar instruments (whether or not it holds the above
securities in its portfolio.) The Fund will not sell put options if, as a
result, more than 50% of the Fund's assets would be required to be segregated to
cover its potential obligations under such put options other than those with
respect to futures and options thereon. In selling put options, there is a risk
that the Fund may be required to buy the underlying security at a
disadvantageous price above the market price.
 
  GENERAL CHARACTERISTICS OF FUTURES.  The Fund may enter into financial futures
contracts or purchase or sell put and call options on such futures as a hedge
against anticipated interest rate or fixed-income market changes, for duration
management and for risk management purposes. Futures are generally bought and
sold on the commodities exchanges where they are listed with payment of initial
and variation margin as described below. The purchase of a futures contract
creates a firm obligation by the Fund, as purchaser, to take delivery from the
seller the specific type of financial instrument called for in the contract at a
specific future time for a specified price (or, with respect to index futures
and Eurodollar instruments, the net cash amount). The sale of a futures contract
creates a firm obligation by the Fund, as seller, to deliver to the buyer the
specific type of financial instrument called for in the contract at a specific
future time for a specified price (or, with respect to index futures and
Eurodollar instruments, the net cash amount). Options on futures contracts are
similar to options on securities except that 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 and obligates the seller to deliver such option.
 
  The Fund's use of financial futures and options thereon will in all cases be
consistent with applicable regulatory requirements and in particular the rules
and regulations of the Commodity Futures Trading Commission and will be entered
into only for bona fide hedging, risk management (including duration management)
or other portfolio management purposes. Typically, maintaining a futures
contract or selling an option thereon requires the Fund to deposit with a
financial intermediary as security for its obligations an amount of cash or
other specified assets (initial margin) which initially is typically 1% to 10%
of the face amount of the contract (but may be higher in some circumstances).
Additional cash or assets (variation margin) may be required to be deposited
thereafter on a daily basis as the mark to market value of the contract
fluctuates. The purchase of options on financial futures involves payment of a
premium for the option without any further obligation on the part of the Fund.
If the Fund exercises an option on a futures contract it will be obligated to
post initial margin (and potential subsequent variation margin) for the
resulting futures position just as it would for any position. Futures contracts
and options thereon are generally settled by entering into an offsetting
transaction but there can be no assurance that the position can be offset prior
to settlement at an advantageous price nor that delivery will occur.
 
  The Fund will not enter into a futures contract or related option (except for
closing transactions) for other than bona fide hedging purposes if, immediately
thereafter, the sum of the amount of its initial margin and premiums on open
futures contracts and options thereon would exceed 5% of the Fund's total assets
(taken at current value); however, in the case of an option that is in-the-money
at the time of the purchase, the in-the-money amount may be excluded in
calculating the 5% limitation. Certain state securities laws to which the Fund
may be subject may further restrict the Fund's ability to engage in transactions
in futures contracts and related options. The segregation requirements with
respect to futures contracts and options thereon are described below.
 
  OPTIONS ON SECURITIES INDICES AND OTHER FINANCIAL INDICES.  The Fund also may
purchase and sell call and put options on financial securities indices and other
financial indices and in so doing can achieve many of the same objectives it
would achieve through the sale or purchase of options on individual securities
or other instruments. Options on financial securities indices and other
financial indices are similar to options on a security or other instrument
except that, rather than settling by physical delivery of the underlying
instrument,
 
                                      B-11
<PAGE>   758
 
they settle by cash settlement, i.e., an option on an index gives the holder the
right to receive, upon exercise of the option, an amount of cash if the closing
level of the index upon which the option is based exceeds, in the case of a
call, or is less than, in the case of a put, the exercise price of the option
(except if, in the case of an OTC option, physical delivery is specified). This
amount of cash is equal to the excess of the closing price of the index over the
exercise price of the option, which also may be multiplied by a formula value.
The seller of the option is obligated, in return for the premium received, to
make delivery of this amount. The gain or loss on an option on an index depends
on price movements in the instruments making up the market, market segment,
industry or other composite on which the underlying index is based, rather than
price movements in individual securities, as is the case with respect to options
on securities.
 
  COMBINED TRANSACTIONS.  If permitted under applicable New Jersey tax law, the
Fund may enter into multiple transactions, including multiple options
transactions, multiple futures transactions and multiple interest rate
transactions and any combination of futures, options and interest rate
transactions ("component" transactions), instead of a single Strategic
Transaction, as part of a single or combined strategy when, in the opinion of
the Adviser, it is in the best interests of the Fund to do so. A combined
transaction will usually contain elements of risk that are present in each of
its component transactions. Although combined transactions are normally entered
into based on the Adviser's judgment that the combined strategies will reduce
risk or otherwise more effectively achieve the desired portfolio management
goal, it is possible that the combination will instead increase such risks or
hinder achievement of the portfolio management objective.
 
  SWAPS, CAPS, FLOORS AND COLLARS.  Among the Strategic Transactions into which
the Fund may enter are interest rate and index swaps and the purchase or sale of
related caps, floors and collars, if permitted under applicable New Jersey tax
law. The Fund expects to enter into these transactions primarily to preserve a
return or spread on a particular investment or portion of its portfolio, as a
duration management technique or to protect against any increase in the price of
securities the Fund anticipates purchasing at a later date. The Fund intends to
use these transactions as hedges and not as speculative investments and will not
sell interest rate caps or floors where it does not own securities or other
instruments providing the income stream the Fund may be obligated to pay.
Interest rate swaps involve the exchange by the Fund with another party of their
respective commitments to pay or receive interest, e.g., an exchange of floating
rate payments for fixed rate payments with respect to a notional amount of
principal. An index swap is an agreement to swap cash flows on a notional amount
based on changes in the values of the reference indices. The purchase of a cap
entitles the purchaser to receive payments on a notional principal amount from
the party selling such cap to the extent that a specified index exceeds a
predetermined interest rate or amount. The purchase of a floor entitles the
purchaser to receive payments on a notional principal amount from the party
selling such floor to the extent that a specified index falls below a
predetermined interest rate or amount. A collar is a combination of a cap and a
floor that preserves a certain return within a predetermined range of interest
rates or values.
 
  The Fund will usually enter into swaps on a net basis, i.e., the two payment
streams are netted out in a cash settlement on the payment date or dates
specified in the instrument, with the Fund receiving or paying, as the case may
be, only the net amount of the two payments. Inasmuch as these swaps, caps,
floors and collars are entered into for good faith hedging purposes, the Adviser
and the Fund believe such obligations do not constitute senior securities under
the 1940 Act and, accordingly, will not treat them as being subject to its
borrowing restrictions. The Fund will not enter into any swap, cap, floor or
collar transaction unless, at the time of entering into such transaction, the
unsecured long-term debt of the Counterparty, combined with any credit
enhancements, is rated at least "A" by S&P or Moody's or has an equivalent
equity rating from an NRSRO or is determined to be of equivalent credit quality
by the Adviser. If there is a default by the Counterparty, the Fund may have
contractual remedies pursuant to the agreements related to the transaction. The
swap market has grown substantially in recent years with a large number of banks
and investment banking firms acting both as principals and agents utilizing
standardized swap documentation. As a result, the swap market has become
relatively liquid. Caps, floors and collars are more recent innovations for
which standardized documentation has not yet been fully developed and,
accordingly, they are less liquid than swaps.
 
  USE OF SEGREGATED AND OTHER SPECIAL ACCOUNTS.  Many Strategic Transactions, in
addition to other requirements, require that the Fund segregate liquid
high-grade assets with its custodian to the extent Fund obligations are not
otherwise "covered" through ownership of the underlying security, financial
instrument or currency. In general, either the full amount of any obligation by
the Fund to pay or deliver securities or assets
 
                                      B-12
<PAGE>   759
 
   
must be covered at all times by the securities, instruments or currency required
to be delivered, or, subject to any regulatory restrictions, an amount of cash
or liquid securities at least equal to the current amount of the obligation must
be segregated with the custodian. The segregated assets cannot be sold or
transferred unless equivalent assets are substituted in their place or it is no
longer necessary to segregate them. For example, a call option written by the
Fund will require the Fund to hold the securities subject to the call (or
securities convertible into the needed securities without additional
consideration) or to segregate liquid high-grade securities sufficient to
purchase and deliver the securities if the call is exercised. A call option sold
by the Fund on an index will require the Fund to own portfolio securities which
correlate with the index or to segregate liquid securities equal to the excess
of the index value over the exercise price on a current basis. A put option
written by the Fund requires the Fund to segregate liquid securities equal to
the exercise price.
    
 
  OTC options entered into by the Fund, including those on securities, financial
instruments or indices and OCC issued and exchange listed index options, will
generally provide for cash settlement. As a result, when the Fund sells these
instruments it will only segregate an amount of assets equal to its accrued net
obligations, as there is no requirement for payment or delivery of amounts in
excess of the net amount. These amounts will equal 100% of the exercise price in
the case of a non cash-settled put, the same as an OCC guaranteed listed option
sold by the Fund, or the in-the-money amount plus any sell-back formula amount
in the case of a cash-settled put or call. In addition, when the Fund sells a
call option on an index at a time when the in-the-money amount exceeds the
exercise price, the Fund will segregate, until the option expires or is closed
out, cash or cash equivalents equal in value to such excess. OCC issued and
exchange listed options sold by the Fund other than those above generally settle
with physical delivery, and the Fund will segregate an amount of assets equal to
the full value of the option. OTC options settling with physical delivery, or
with an election of either physical delivery or cash settlement, will be treated
the same as other options settling with physical delivery.
 
  In the case of a futures contract or an option thereon, the Fund must deposit
initial margin and possible daily variation margin in addition to segregating
assets sufficient to meet its obligation to purchase or provide securities or
currencies, or to pay the amount owed at the expiration of an index-based
futures contract. Such assets may consist of cash, cash equivalents, liquid debt
or equity securities or other acceptable assets.
 
   
  With respect to swaps, the Fund will accrue the net amount of the excess, if
any, of its obligations over its entitlements with respect to each swap on a
daily basis and will segregate an amount of cash or liquid securities having a
value equal to the accrued excess. Caps, floors and collars require segregation
of assets with a value equal to the Fund's net obligation, if any.
    
 
  Strategic Transactions may be covered by other means when consistent with
applicable regulatory policies. The Fund may also enter into offsetting
transactions so that its combined position, coupled with any segregated assets,
equals its net outstanding obligation in related options and Strategic
Transactions. For example, the Fund could purchase a put option if the strike
price of that option is the same or higher than the strike price of a put option
sold by the Fund. Moreover, instead of segregating assets if the Fund held a
futures or forward contract, it could purchase a put option on the same futures
or forward contract with a strike price as high or higher than the price of the
contract held. Other Strategic Transactions may also be offset in combinations.
If the offsetting transaction terminates at the time of or after the primary
transaction no segregation is required, but if it terminates prior to such time,
assets equal to any remaining obligation would need to be segregated.
 
  The Fund's activities involving Strategic Transactions may be limited by the
requirements of Subchapter M of the Code for qualification as a regulated
investment company. See "Tax Status" in the Prospectus.

                  DESCRIPTION OF MUNICIPAL SECURITIES RATINGS
 
  STANDARD & POOR'S RATINGS GROUP--A brief description of the applicable
Standard & Poor's Ratings Group (S&P) rating symbols and their meanings (as
published by S&P) follows:
 
  1.  DEBT
 
   
    A S&P corporate or municipal debt rating is a current assessment of the
  creditworthiness of an obligor with respect to a specific obligation. This
  assessment may take into consideration obligors such as guarantors, insurers,
  or lessees.
    
 
    The debt rating is not a recommendation to purchase, sell or hold a
  security, inasmuch as it does not comment as to market price or suitability
  for a particular investor.
 
    The ratings are based on current information furnished by the issuer or
  obtained by S&P from other sources it considers reliable. S&P 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 based on
  other circumstances.
 
     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;
 
     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.
 
<TABLE>
  <S>         <C>
  AAA         Debt rated 'AAA' has the highest rating assigned by S&P.
              Capacity to pay interest and repay principal is extremely
              strong.
 
  AA          Debt rated 'AA' has a very strong capacity to pay interest
              and repay principal and differs from the higher rated issues
              only in small degree.
 
  A           Debt rated 'A' has a strong capacity to pay interest and
              repay principal although it is somewhat more susceptible to
              the adverse effects of changes in circumstances and economic
              conditions than debt in higher rated categories.
 
  BBB         Debt rated 'BBB' is regarded as having an adequate capacity
              to pay interest and repay principal. Whereas it normally
              exhibits adequate protection parameters, adverse economic
              conditions or changing circumstances are more likely to lead
              to a weakened capacity to pay interest and repay principal
              for debt in this category than in higher rated categories.
 
  BB          Debt rated 'BB', 'B', 'CCC', 'CC' and 'C' is regarded as
  B           having as predominantly speculative characteristics with
  CCC         respect to capacity to pay interest and repay principal.
  CC          'BB' indicates the least degree of speculation and 'C' the
  C           highest. While such debt will likely have some quality and
              protective characteristics, these are outweighed by large
              uncertainties or large exposures to adverse conditions.
 
  BB          Debt rated 'BB' has less near-term vulnerability to default
              than other speculative issues. However, it faces major
              ongoing uncertainties or exposure to adverse business,
              financial, or economic conditions which could lead to
              inadequate capacity to meet timely interest and principal
              payments. The 'BB' rating category is also used for debt
              subordinated to senior debt that is assigned an actual or
              implied 'BBB-' rating.
 
  B           Debt rated 'B' has a greater vulnerability to default but
              currently has the capacity to meet interest payments and
              principal repayments. Adverse business, financial, or
              economic conditions will likely impair capacity or
              willingness to pay interest and repay principal. The 'B'
              rating category is also used for debt subordinated to senior
              debt that is assigned an actual or implied 'BB' or 'BB-'
              rating.

<PAGE>   761
<TABLE>
<S>           <C>
  CCC         Debt rated 'CCC' has a currently identifiable vulnerability
              to default, and is dependent upon favorable business,
              financial, and economic conditions to meet timely payment of
              interest and repayment of principal. In the event of adverse
              business, financial, or economic conditions, it is not
              likely to have the capacity to pay interest and repay
              principal. The 'CCC' rating category is also used for debt
              subordinated to senior debt that is assigned an actual or
              implied 'B' or 'B-' rating.
 
  CC          The rating 'CC' typically is applied to debt subordinated to
              senior debt that is assigned an actual or implied 'CCC'
              rating.
 
  C           The rating 'C' typically is applied to debt subordinated to
              senior debt which is assigned an actual or implied 'CCC-'
              debt rating. The 'C' rating may be used to cover a situation
              where a bankruptcy petition has been filed, but debt service
              payments are continued.
 
  CI          The rating 'CI' is reserved for income bonds on which no
              interest is being paid.
 
  D           Debt rated 'D' is in payment default. The 'D' rating
              category is used when interest payments or principal
              payments are not made on the date due even if the applicable
              grace period has not expired, unless S&P believes that such
              payments will be made during such grace period. The 'D'
              rating also will be used upon the filing of a bankruptcy
              petition if debt service payments are jeopardized.
 
              PLUS (+) or MINUS (-): The ratings from 'AA' to 'CCC' may be
              modified by the addition of a plus or minus sign to show relative
              standing within the major categories.
 
  C           The letter "c" indicates that the holder's option to tender
              the security for purchase may be canceled under certain
              prestated conditions enumerated in the tender option
              documents.
  I           The letter "i" indicates the rating is implied. Such ratings
              are assigned only on request to entities that do not have
              specific debt issues to be rated. In addition, implied
              ratings are assigned to governments that have not requested
              explicit ratings for specific debt issues. Implied ratings
              on governments represent the sovereign ceiling or upper
              limit for ratings on specific debt issues of entities
              domiciled in the country.
  L           The letter "L" indicates that the rating pertains to the
              principal amount of those bonds to the extent that the
              underlying deposit collateral is federally insured and
              interest is adequately collateralized. In the case of
              certificates of deposit, the letter "L" indicates that the
              deposit, combined with other deposits being held in the same
              right and capacity, will be honored for principal and
              accrued pre-default interest up to the federal insurance
              limits within 30 days after closing of the insured
              institution or, in the event that the deposit is assumed by
              a successor insured institution, upon maturity.
  P           The letter "p" indicates that the rating is provisional. A
              provisional rating assumes the successful completion of the
              project being financed by the debt being rated and indicates
              that payment of debt service requirements is largely or
              entirely dependent upon the successful and timely completion
              of the project. This rating, however, while addressing
              credit quality subsequent to completion of the project,
              makes no comment on the likelihood of, or the risk of
              default upon failure of, such completion. The investor
              should exercise his own judgement with respect to such
              likelihood and risk.
              * Continuance of the rating is contingent upon S&P's receipt
              of an executed copy of the escrow agreement or closing
              documentation confirming investments and cash flows.
  NR          Indicates that no public rating has been requested, that
              there is insufficient information on which to base a rating,
              or that S&P does not rate a particular type of obligation as
              a matter of policy.
              DEBT OBLIGATIONS OF ISSUERS OUTSIDE THE UNITED STATES AND
              ITS TERRITORIES are rated on the same basis as domestic
              corporate and municipal issues. The ratings measure the
              creditworthiness of the obligor but do not take into account
              currency exchange and related uncertainties.

<PAGE>   762
 
  BOND INVESTMENT QUALITY STANDARDS:  Under present commercial bank regulations
issued by the Comptroller of the Currency, bonds rated in the top four
categories ("AAA", "AA", "A", "BBB" commonly known as "investment guide"
ratings) are generally regarded as eligible for bank investment. In addition,
the laws of various states governing legal investments impose certain rating or
other standards for obligations eligible for investment by savings banks, trust
companies, insurance companies, and fiduciaries generally.
 
  2.  MUNICIPAL NOTES
 
    A S&P note rating reflects the liquidity factors and market-access risks
  unique to notes. Notes maturing in 3 years or less will likely receive a note
  rating. Notes maturing beyond 3 years will most likely receive a long-term
  debt rating.
 
    The following criteria will be used in making that assessment:
 
    -- Amortization schedule (the larger the final maturity relative to other
       maturities, the more likely the issue is to be treated as a note).
 
    -- Source of payment (the more the issue depends on the market for its
       refinancing, the more likely it is to be treated as a note).
 
     The note rating symbols and definitions are as follows:
 
<TABLE>
  <S>         <C>
  SP-1        Strong capacity to pay principal and interest. Issues
              determined to possess very strong characteristics are a plus
              (+) designation.
 
  SP-2        Satisfactory capacity to pay principal and interest, with
              some vulnerability to adverse financial and economic changes
              over the term of the notes.
 
  SP-3        Speculative capacity to pay principal and interest.
</TABLE>
 
  3.  COMMERCIAL PAPER
 
    A S&P 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.
 
    Ratings are graded into several categories, ranging from 'A-1' for the
  highest-quality obligations to 'D' for the lowest. These categories are as
  follows:
 
<TABLE>
  <S>         <C>
  A-1         This highest category indicates that the degree of safety
              regarding timely payment is strong. Those issues determined
              to possess extremely strong safety characteristics are
              denoted with a plus sign (+) designation.
 
  A-2         Capacity for timely payment on issues with this designation
              is satisfactory. However, the relative degree of safety is
              not as high as for issues designated 'A-1'.
 
  A-3         Issues carrying this designation have adequate capacity for
              timely payment. They are, however, more vulnerable to the
              adverse effects of changes in circumstances than obligations
              carrying the higher designations.
 
  B           Issues rated 'B' are regarded as having only speculative
              capacity for timely payment.
 
  C           This rating is assigned to short-term debt obligations with
              a doubtful capacity for payment.
 
  D           Debt rated 'D' is in payment default. The 'D' rating
              category is used when interest payments or principal
              payments are not made on the date due, even if the
              applicable grace period has not expired, unless S&P believes
              that such payments will be made during such grace period.
 
  A commercial paper rating is not a recommendation to purchase or sell a
  security. The ratings are based on current information furnished to S&P
  by the issuer or obtained 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.
</TABLE>
 
                                      B-16
<PAGE>   763
 
  4.  TAX-EXEMPT DUAL RATINGS
 
  S&P assigns "dual" ratings to all debt issues that have a put option or demand
feature as part of their structure.
 
  The first rating addresses the likelihood of repayment of principal and
interest as due, and the second rating addresses only the demand feature. The
long-term debt rating symbols are used for bonds to denote the long-term
maturity and the commercial paper rating symbols for the put option (for
example, 'AAA/A-1+'). With short-term demand debt, S&P's note rating symbols are
used with the commercial paper rating symbols (for example, 'SP-1+/A-1+').
 
  MOODY'S INVESTORS SERVICE, INC.--A brief description of the applicable Moody's
Investors Service, Inc. ("Moody's") rating symbols and their meanings (as
published by Moody's) follows:
 
  1.  LONG-TERM MUNICIPAL BONDS
 
<TABLE>
  <S>         <C>
  AAA         Bonds which are rated Aaa are judged to be of the best
              quality. They carry the smallest degree of investment risk
              and are generally referred to as "gilt edged." Interest
              payments are protected by a large or by an exceptionally
              stable margin and principal is secure. While the various
              protective elements are likely to change, such changes as
              can be visualized are most unlikely to impair the
              fundamentally strong position of such issues.
 
  AA          Bonds which are rated Aa are judged to be of high quality by
              all standards. Together with the Aaa group they comprise
              what are generally known as high grade bonds. They are rated
              lower than the best bonds because margins of protection may
              not be as large as in Aaa securities or fluctuation of
              protective elements may be of greater amplitude or there may
              be other elements present which make the long-term risk
              appear somewhat larger than the Aaa securities.
 
  A           Bonds which are rated A possess many favorable investment
              attributes and are to be considered as upper-medium-grade
              obligations. Factors giving security to principal and
              interest are considered adequate, but elements may be
              present which suggest a susceptibility to impairment some
              time in the future.
 
  BAA         Bonds which are rated Baa are considered as medium-grade
              obligations, (i.e., they are neither highly protected nor
              poorly secured). Interest payments and principal security
              appear adequate for the present but certain protective
              elements may be lacking or may be characteristically
              unreliable over any great length of time. Such bonds lack
              outstanding investment characteristics and in fact have
              speculative characteristics as well.
 
  BA          Bonds which are rated Ba are judged to have speculative
              elements; their future cannot be considered as well-assured.
              Often the protection of interest and principal payments may
              be very moderate, and thereby not well safeguarded during
              both good and bad times over the future. Uncertainty of
              position characterizes bonds in this class.
 
  B           Bonds which are rated B generally lack characteristics of
              the desirable investment. Assurance of interest and
              principal payments or of maintenance of other terms of the
              contract over any long period of time may be small.
 
  CAA         Bonds which are rated Caa are of poor standing. Such issues
              may be in default or there may be present elements of danger
              with respect to principal or interest.
 
  CA          Bonds which are rated Ca represent obligations which are
              speculative in a high degree. Such issues are often in
              default or have other marked shortcomings.
 
  C           Bonds which are rated C are the lowest rated class of bonds,
              and issues so rated can be regarded as having extremely poor
              prospects of ever attaining any real investment standing.

  CON (..)    Bonds for which the security depends upon the completion of
              some act or the fulfillment of some condition are rated
              conditionally and designated with the prefix "con" followed
              by the rating in parentheses. These are bonds secured by:
              (a) earnings of projects under construction, (b) earnings of
              projects unseasoned in operating experience, (c) rentals
              that begin when facilities are completed, or (d) payments to
              which some other limiting condition attaches the
              parenthetical rating denotes the probable credit stature
              upon completion of construction or elimination of the basis
              of the condition.
 
  (P) (..)    When applied to forward delivery bonds, indicates that the
              rating is provisional pending the delivery of the bonds. The
              rating may be revised prior to delivery if changes occur in
              the legal documents or the underlying credit quality of the
              bonds.
 
  NOTE:       Moody's applies numerical modifiers, 1, 2 and 3 in each
              generic rating classification from AA to B. The modifier 1
              indicates that the company ranks in the higher end of its
              generic rating category; the modifier 2 indicates a
              mid-range ranking; and the modifier 3 indicates that the
              company ranks in the lower end of its generic rating
              category.
 
    
 
  2.  SHORT-TERM EXEMPT NOTES
 
    Moody's ratings for state and municipal short-term obligations will be
  designated Moody's Investment Grade or (MIG). Such ratings recognize the
  differences between short-term credit risk and long-term risk. Factors
  affecting the liquidity of the borrower and short-term cyclical elements are
  critical in short-term ratings, while other factors of major importance in
  bond risk, long-term secular trends for example, may be less important over
  the short run. A short-term rating may also be assigned on an issue having a
  demand feature-variable rate demand obligation. Such ratings will be
  designated as VMIG, SG or, if the demand feature is not rated, as NR.
 
    Moody's short-term ratings are designated Moody's Investment Grade as MIG 1
  or VMIG 1 through MIG 4 or VMIG 4. As the name implies, when Moody's assigns a
  MIG or VMIG rating, all categories define an investment grade situation.
 
    MIG 1/VMIG 1. This designation denotes best quality. There is present strong
  protection by established cash flows, superior liquidity support or
  demonstrated broad-based access to the market for refinancing.
 
    MIG 2/VMIG 2. This designation denotes high quality. Margins of protection
  are ample although not so large as in the preceding group.
 
    MIG 3/VMIG 3. This designation denotes favorable quality. All security
  elements are accounted for but there is lacking the undeniable strength of the
  preceding grades. Liquidity and cash flow protection may be narrow and market
  access for refinancing is likely to be less well established.
 
    MIG 4/VMIG 4. This designation denotes adequate quality. Protection commonly
  regarded as required of an investment security is present and although not
  distinctly or predominantly speculative, there is specific risk.
 
    SG. This designation denotes speculative quality. Debt instruments in this
  category lack margins of protection.
 
  3.  TAX-EXEMPT COMMERCIAL PAPER
 
   
    Moody's short-term debt ratings are opinions of the ability of issuers to
  repay punctually promissory obligations not having an original maturity in
  excess of nine months. Moody's makes no representation that such obligations
  are exempt from registration under the Securities Act of 1933, nor does it
  represent that any specific note is a valid obligation of a rated issuer or
  issued in conformity with any applicable law.
    
 
    Moody's employs the following three designations, all judged to be
  investment grade, to indicate the relative repayment ability of rated issuers:
 
   
       Issuers rated Prime-1 (for related supporting institutions) have a
     superior capacity for repayment of short-term promissory obligations.
     Prime-1 repayment capacity will normally be evidenced by the following
     characteristics:
    
 
                                      B-18
<PAGE>   765
 
   
         - Leading market positions in well established industries.
    
 
   
         - High rates of return on funds employed.
    
 
   
         - Conservative capitalization structures with moderate reliance on debt
           and ample asset protection.
    
 
   
         - Broad margins in earning coverage of fixed financial charges and high
           internal cash generation.
    
 
   
         - Well established access to a range of financial markets and assured
           sources of alternate liquidity.
    
 
   
       Issuers rated Prime-2 (or related supporting institutions) have a strong
     capacity for repayment of short-term promissory obligations. This will
     normally be evidenced by many of the characteristics cited above but to a
     lesser degree. Earnings trends and coverage ratios, while sound, will be
     more subject to variation. Capitalization characteristics, while still
     appropriate, may be more affected by external conditions. Ample alternate
     liquidity is maintained.
    
 
   
       Issuers rated Prime-3 (or related supporting institutions) have an
     acceptable capacity for repayment of short-term promissory obligations. The
     effects of industry characteristics and market composition may be more
     pronounced. Variability in earnings and profitability may result in changes
     in the level of debt protection measurements and the requirement for
     relatively high financial leverage. Adequate alternate liquidity is
     maintained.
    
 
   
       Issuers rated Not Prime do not fall within any of the Prime rating
     categories.

  Each of the trustees holds the same position with each of the funds in the
Fund Complex. As of December 31, 1996, there were 51 funds in the Fund Complex.
Each trustee who is not an affiliated person of VKAC, the Advisers, the
Distributor, ACCESS or Morgan Stanley (each a "Non-Affiliated Trustee") is
compensated by an annual retainer and meeting fees for services to the funds in
the Fund Complex. Each fund in the Fund Complex provides a deferred compensation
plan to its Non-Affiliated Trustees that allows trustees to defer receipt of
their compensation and earn a return on such deferred amounts based upon the
return of the common shares of the funds in the Fund Complex as more fully
described below. Each fund in the Fund Complex also provides a retirement plan
to its Non-Affiliated Trustees that provides Non-Affiliated Trustees with
compensation after retirement, provided that certain eligibility requirements
are met as more fully described below.
    
 
   
  The compensation of each Non-Affiliated Trustee from each fund in the Fund
Complex advised by Advisory Corp. (each a "VK Fund" and collectively the "VK
Funds") includes an annual retainer in an amount equal to $2,500 per calendar
year, due in four quarterly installments on the first business day of each
calendar quarter. Each Non-Affiliated Trustee receives a per meeting fee from
each VK Fund in the amount of $125 per regular quarterly meeting attended by the
Non-Affiliated Trustee, due on the date of such meeting, plus reasonable
expenses incurred by the Non-Affiliated Trustee in connection with his or her
services as a trustee. Each Non-Affiliated Trustee receives a per meeting fee
from each VK Fund in the amount of $125 per special meeting attended by the
Non-Affiliated Trustee, due on the date of such meeting, plus reasonable
expenses incurred by the Non-Affiliated Trustee in connection with his or her
services as a trustee, provided that no compensation will be paid in connection
with certain telephonic special meetings.
    
 
   
  The compensation of each Non-Affiliated Trustee from the funds in the Fund
Complex advised by Asset Management (each an "AC Fund" or collectively the "AC
Funds") includes an annual retainer in an amount equal to $35,000 per calendar
year, due in four quarterly installments on the first business day of each
calendar quarter. The AC Funds pay each Non-Affiliated Trustee a per meeting fee
in the amount of $2,000 per regular quarterly meeting attended by the
Non-Affiliated Trustee, due on the date of such meeting, plus reasonable

expenses incurred by the Non-Affiliated Trustee in connection with his or her
services as a trustee. Payment of the annual retainer and the regular meeting
fee is allocated among the AC Funds (i) 50% on the basis of the relative net
assets of each AC Fund to the aggregate net assets of all the AC Funds and (ii)
50% equally to each AC Fund, in each case as of the last business day of the
preceding calendar quarter. Each AC Fund which is the subject of a special
meeting of the trustees generally pays each Non-Affiliated Trustee a per meeting
fee in the amount of $125 per special meeting attended by the Non-Affiliated
Trustee, due on the date of such meeting, plus reasonable expenses incurred by
the Non-Affiliated Trustee in connection with his or her services as a trustee,
provided that no compensation will be paid in connection with certain telephonic
special meetings.
    
 
   
  The trustees approved an aggregate compensation cap with respect to funds in
the Fund Complex of $84,000 per Non-Affiliated Trustee per year (excluding any
retirement benefits) for the period July 22, 1995 through December 31, 1996,
subject to the net assets and the number of funds in the Fund Complex as of July
21, 1995 and certain other exceptions. For the calendar year ended December 31,
1996, certain trustees received aggregate compensation from the funds in the
Fund Complex over $84,000 due to compensation received but not subject to the
cap, including compensation from new funds added to the Fund Complex after July
22, 1995 and certain special meetings in 1996. In addition, each of Advisory
Corp. or Asset Management, as the case may be, agreed to reimburse each fund in
the Fund Complex through December 31, 1996 for any increase in the aggregate
trustee's compensation over the aggregate compensation paid by such fund in its
1994 fiscal year, provided that if a fund did not exist for the entire 1994
fiscal year appropriate adjustments will be made.
    
 
   
  Each Non-Affiliated Trustee generally can elect to defer receipt of all or a
portion of the compensation earned by such Non-Affiliated Trustee until
retirement. Amounts deferred are retained by the Fund and earn a rate of return
determined by reference to the return on the common shares of such Fund or other
funds in the Fund Complex as selected by the respective Non-Affiliated Trustee,
with the same economic effect as if such Non-Affiliated Trustee had invested in
one or more funds in the Fund Complex. To the extent permitted by the 1940 Act,
the Fund may invest in securities of those funds selected by the Non-Affiliated
Trustees in order to match the deferred compensation obligation. The deferred
compensation plan is not funded and obligations thereunder represent general
unsecured claims against the general assets of the Fund.
    
 
   
  Each fund in the Fund Complex has adopted a retirement plan. Under the Fund's
retirement plan, a Non-Affiliated Trustee who is receiving trustee's
compensation from the Fund prior to such Non-Affiliated Trustee's retirement,
has at least 10 years of service (including years of service prior to adoption
of the retirement plan) and retires at or after attaining the age of 60, is
eligible to receive a retirement benefit equal to $2,500 per year for each of
the ten years following such trustee's retirement from the Fund. Trustees
retiring prior to the age of 60 or with fewer than 10 years but more than 5
years of service may receive reduced retirement benefits from the Fund. Each
trustee has served as a member of the Board of Trustees since he or she was
first appointed or elected in the year set forth below. The retirement plan
contains a Fund Complex retirement benefit cap of $60,000 per year. Asset
Management has reimbursed each AC Fund for the expenses related to the
retirement plan through December 31, 1996.

*  Currently a member of the Board of Trustees. Mr. Phillip B. Rooney also is a
   current member of the Board of Trustees but is not included in the
   compensation table because he did not serve on the Board of Trustees or
   receive any compensation from the Trust prior to April 14, 1997. Messrs.
   McDonnell and Powell, also trustees of the Trust during all or a portion of
   the Trust's last fiscal year, are not included in the compensation table
   because they are affiliated persons of the Advisers and are not eligible for
   compensation or retirement benefits from the Trust.
    
 
   
(1) Persons not designated by an asterisk are not currently members of the Board
    of Trustees, but were members of the Board of Trustees during the Trust's
    most recently completed fiscal year. Messrs. Gaughan and Rees retired from
    the Board of Trustees on January 26, 1996 and January 29, 1996,
    respectively. Mr. Sheehan was removed from the Board of Trustees effective
    January 29, 1996. Messrs. Hilsman, Miller and Woodside retired from the
    Board of Trustees on December 31, 1996.
    
 
   
(2) The amounts shown in this column represent the aggregate compensation before
    deferral from all eight series of the Trust, including the Fund, with
    respect to the Trust's fiscal year ended December 31, 1996. The detail of
    aggregate compensation before deferral for each series, including the Fund,
    are shown in Table A below. Certain trustees deferred compensation from the
    Trust during the fiscal year ended December 31, 1996; the aggregate
    compensation deferred from all eight series of the Trust, including the
    Fund, is as follows: Mr. Branagan, $5,750; Mr. Gaughan, $3,750; Ms. Heagy,
    $15,000; Mr. Kennedy, $9,500; Mr. Miller, $20,000; Mr. Nelson, $20,000; Mr.
    Robinson, $18,000; and Mr. Whalen, $19,625. The details of amounts deferred
    for each series, including the Fund, are shown in Table B below. Amounts
    deferred are retained by the respective fund and earn a rate of return
    determined by reference to either the return on the common shares of such
    fund or other funds in the Fund Complex as selected by the respective
    Non-Affiliated Trustee, with the same economic effect as if such
    Non-Affiliated Trustee had invested in one or more funds in the Fund
    Complex. To the extent permitted by the 1940 Act, each fund may invest in
    securities of those funds selected by the Non-Affiliated Trustees in order
    to match the deferred compensation obligation. The cumulative deferred
    compensation (including interest) accrued with respect to each trustee from
    all eight series of the Trust, including the Fund, as of the Trust's fiscal

    year ended December 31, 1996 is as follows: Mr. Branagan, $5,678; Mr.
    Gaughan, $20,094; Ms. Heagy, $20,472; Mr. Kennedy, $47,294; Mr. Miller,
    $55,827; Mr. Nelson, $57,771; Mr. Robinson, $54,847; and Mr. Whalen,
    $49,269. The details of cumulative deferred compensation (including
    interest) for each series, including the Fund, are shown in Table C below.
    The deferred compensation plan is described above the Compensation Table.
    
 
   
(3) The amounts shown in this column represent the retirement benefits accrued
    by all eight series of the Trust, including the Fund, with respect to the
    Trust's fiscal year ended December 31, 1996. The details of retirement
    benefits accrued for each series, including the Fund, are shown in Table D
    below. The retirement plan is described above the Compensation Table.
    
 
   
(4) This is the estimated maximum annual benefits payable by the Trust in each
    year of the 10-year period commencing in the year of such trustee's
    retirement from the Trust. The estimated maximum annual benefit, except for
    trustees who have retired or are near retirement, is based upon $2,500 per
    series assuming: the trustee has 10 or more years of service on the Board of
    Trustees (including years of service prior to the adoption of the retirement
    plan) and retires at or after attaining the age of 60. Trustees retiring
    prior to the age of 60 or with fewer than 10 years of service for a series
    of the Trust may receive reduced retirement benefits from such series. The
    actual annual benefit may be less if the trustee is subject to the Fund
    Complex retirement benefit cap or if the trustee is not fully vested at the
    time of retirement. Each Non-Affiliated Trustee of the Board of Trustees has
    served as a member of the Board of Trustees since he or she was first
    appointed or elected in the year set forth in Table E below.
    
 
   
(5) The amounts shown in this column represent the aggregate compensation paid
    by all 51 of the investment companies in the Fund Complex as of December 31,
    1996 before deferral by the trustees under the deferred compensation plan.
    Certain trustees deferred all or a portion of their aggregate compensation
    from the Fund Complex during the calendar year ended December 31, 1996. The
    deferred compensation earns a rate of return determined by reference to the
    return on the shares of the funds in the Fund Complex as selected by the
    respective Non-Affiliated Trustee, with the same economic effect as if such
    Non-Affiliated Trustee had invested in one or more funds in the Fund
    Complex. To the extent permitted by the 1940 Act, the Fund may invest in
    securities of those investment companies selected by the Non-Affiliated
    Trustees in order to match the deferred compensation obligation. The
    trustees' Fund Complex compensation cap covered the period July 22, 1995
    through December 31, 1996. For the calendar year ended December 31, 1996,
    certain trustees received compensation over $84,000 in the aggregate due to
    compensation received but not subject to the cap, including compensation
    from new funds added to the Fund Complex after July 22, 1995 and certain
    special meetings in 1996. The Advisers and their affiliates also serve as
    investment adviser for other investment companies; however, with the
    exception of Messrs. McDonnell, Powell and Whalen, the trustees were not
    trustees of such investment companies. Combining the Fund Complex with other
    investment companies advised by the Advisers and their affiliates, Mr.
    Whalen received Total Compensation of $243,375 during the calendar year
    ended December 31, 1996.
    
 
   
  As of April 4, 1997, the trustees and officers of the Fund as a group owned
less than 1% of the shares of the Fund.

                     INVESTMENT ADVISORY AND OTHER SERVICES
 
INVESTMENT ADVISORY AGREEMENT
 
   
  The Adviser was incorporated as a Delaware corporation in 1982 (and through
December 31, 1987 transacted business under the name of American Portfolio
Advisory Service Inc.).
    
 
   
  The Adviser is a wholly-owned subsidiary of Van Kampen American Capital, Inc.
("VKAC"), which is a wholly-owned subsidiary of VK/AC Holding, Inc. VK/AC
Holding, Inc. is a wholly-owned subsidiary of MSAM Holdings II, Inc. which, in
turn, is a wholly-owned subsidiary of Morgan Stanley Group Inc. The principal
office of the Fund, the Adviser, the Distributor and VKAC is located at One
Parkview Plaza, Oakbrook Terrace, Illinois 60181.
    
 
   
  Morgan Stanley Group Inc. and various of its directly or indirectly owned
subsidiaries, including Morgan Stanley & Co. Incorporated, a registered
broker-dealer and investment adviser, and Morgan Stanley International, are
engaged in a wide range of financial services. Their principal businesses
include securities underwriting, distribution and trading; merger, acquisition,
restructuring and other corporate finance advisory activities; merchant banking;
stock brokerage and research services; asset management; trading of futures,
options, foreign exchange, commodities and swaps (involving foreign exchange,
commodities, indices and interest rates); real estate advice, financing and
investing; and global custody, securities clearance services and securities
lending.
    
 
   
  On February 5, 1997, Morgan Stanley Group Inc. and Dean Witter, Discover & Co.
announced that they had entered into an Agreement and Plan of Merger to form
Morgan Stanley, Dean Witter, Discover & Co. Subject to certain conditions being
met, it is currently anticipated that the transaction will close in mid-1997.
Thereafter, Van Kampen American Capital Asset Management, Inc. will be an
indirect subsidiary of Morgan Stanley, Dean Witter, Discover & Co.
    
 
   
  Dean Witter, Discover & Co. is a financial services company with three major
businesses; full service brokerage, credit services and asset management.

<PAGE>   776
 
   
  The investment advisory agreement between the Adviser and the Fund provides
that the Adviser will supply investment research and portfolio management,
including the selection of securities for the Fund to purchase. The Adviser also
administers the business affairs of the Fund, furnishes offices, necessary
facilities and equipment, provides administrative services, and permits its
officers and employees to serve without compensation as officers of the Fund and
trustees of the Trust if duly elected to such positions.
    
 
  The agreement provides that the Adviser shall not be liable for any error of
judgment or of law, or for any loss suffered by the Fund in connection with the
matters to which the agreement relates, except a loss resulting from willful
misfeasance, bad faith, or gross negligence on the part of the Adviser in the
performance of its obligations and duties, or by reason of its reckless
disregard of its obligations and duties under the agreement.
 
  The Adviser's activities are subject to the review and supervision of the
Board of Trustees of the Trust, of which the Fund is a series, to whom the
Adviser renders periodic reports of the Fund's investment activities.
 
  The agreement will continue in effect from year to year if specifically
approved by the Trustees of the Trust, of which the Fund is a separate series
(or by the Fund's shareholders), and by the disinterested trustees in compliance
with the requirements of the 1940 Act. The agreement may be terminated without
penalty upon 60 days' written notice by either party thereto and will
automatically terminate in the event of assignment.
 
  The investment advisory agreement specifies that the Adviser will reimburse
the Fund for annual expenses of the Fund which exceed the most stringent limit
prescribed by any state in which the Fund's shares are offered for sale.
Currently, the most stringent limit in any state would require such
reimbursement to the extent that aggregate operating expenses of the Fund
(excluding interest, taxes and other expenses which may be excludable under
applicable state law) exceed in any fiscal year 2 1/2% of the average annual net
assets of the Fund up to $30 million, 2% of the average annual net assets of the
Fund of the next $70 million, and 1 1/2% of the remaining average annual net
assets of the Fund. In addition to making any required reimbursements, the
Adviser may in its discretion, but is not obligated to, waive all or any portion
of its fee or assume all or any portion of the expenses of the Fund.
 
   
  For the year ended December 31, 1996, 1995, and 1994, the Fund paid advisory
expenses of $0, $0 and $0, respectively.
    
 
OTHER AGREEMENTS
 
   
  ACCOUNTING SERVICES AGREEMENT. The Fund has also entered into an accounting
services agreement pursuant to which the Adviser provides accounting services
supplementary to those provided by the Custodian. Such services are expected to
enable the Fund to more closely monitor and maintain its accounts and records.
The Fund shares together with the other Van Kampen American Capital mutual funds
in the cost of providing such services, with 25% of such costs shared
proportionately based on the respective number of classes of securities issued
per fund and the remaining 75% of such cost based proportionally on their
respective net assets per fund.
    
 
   
  For the years ending December 31, 1996, 1995, and 1994, the Adviser waived its
cost of providing accounting services to the Fund.
    
 
   
  LEGAL SERVICES AGREEMENT. The Fund and each of the other Van Kampen American
Capital Funds advised by the Adviser and distributed by the Distributor have
entered into Legal Services Agreements pursuant to which Van Kampen American
Capital provides legal services, including without limitation: accurate
maintenance of the fund's minute books and records, preparation and oversight of
the fund's regulatory reports, and other information provided to shareholders,
as well as responding to day-to-day legal issues on behalf of the funds. Payment
by the Fund for such services is made on a cost basis for the salary and salary
related benefits, including but not limited to bonuses, group insurances and
other regular wages for the employment of personnel, as well as overhead and the
expenses related to the office space and the equipment necessary to render the
legal services. Other funds distributed by the Distributor also receive legal
services from Van Kampen American Capital. Of the total costs for legal services
provided to funds distributed by the Distributor, one half of such costs are
allocated equally to each fund and the remaining one half of such costs are
allocated to specific funds based on monthly time records.

  For the years ending December 31, 1996, 1995 and 1994, Van Kampen American
Capital waived its cost of providing legal services to the Fund.
    
 
   
                     CUSTODIAN AND INDEPENDENT ACCOUNTANTS
    
 
  State Street Bank and Trust Company, 225 Franklin Street, P.O. Box 1713,
Boston, MA 02105-1713, is the custodian of the Fund and has custody of all
securities and cash of the Fund. The custodian, among other things, attends to
the collection of principal and income, and payment for and collection of
proceeds of securities bought and sold by the Fund.
 
   
  The independent accountants for the Fund are KPMG Peat Marwick LLP, Chicago,
Illinois. The selection of independent accountants will be subject to
ratification by the shareholders of the Fund at any annual meeting of
shareholders.
    
 
                PORTFOLIO TRANSACTIONS AND BROKERAGE ALLOCATION
 
  The Adviser will place orders for portfolio transactions for the Fund with
broker-dealer firms giving consideration to the quality, quantity and nature of
each firm's professional services. These services include execution, clearance
procedures, wire service quotations and statistical and other research
information provided to the Fund, or the Adviser, including quotations necessary
to determine the value of the Fund's net assets. Any research benefits derived
are available for all clients of the Adviser. Since statistical and other
research information is only supplementary to the research efforts of the
Adviser to the Fund and still must be analyzed and reviewed by its staff, the
receipt of research information is not expected to materially reduce its
expenses. In selecting among the firms believed to meet the criteria for
handling a particular transaction, the Fund's Adviser may take into
consideration that certain firms have sold or are selling shares of the Fund and
that certain firms provide market, statistical or other research information to
the Fund and the Adviser, and may select firms that are affiliated with the
Fund, the Adviser, or its distributor and other principal underwriters.
 
  If it is believed to be in the best interests of the Fund, the Adviser may
place portfolio transactions with brokers who provide the types of service
described above, even if it means the Fund will have to pay a higher commission
(or, if the broker's profit is part of the cost of the security, will have to
pay a higher price for the security), than would be the case if no weight were
given to the broker's furnishing of those research services. This will be done,
however, only if, in the opinion of the Fund's Adviser, the amount of additional
commission or increased cost is reasonable in relation to the value of such
services.
 
  In selecting among the firms believed to meet the criteria for handling a
particular transaction, the Adviser may take into consideration that certain
firms (i) provide market, statistical or other research information such as set
forth above to the Fund and the Adviser, (ii) have sold or are selling shares of
the Fund and (iii) may select firms that are affiliated with the Fund, its
investment adviser or its distributor and other principal underwriters. If
purchases or sales of securities of the Fund and of one or more other investment
companies or clients supervised by the Adviser are considered at or about the
same time, transactions in such securities will be allocated among the several
investment companies and clients in a manner deemed equitable to all by the
Adviser, taking into account the respective sizes of the Fund and other
investment companies and clients and the amount of securities to be purchased or
sold. Although it is possible that in some cases this procedure could have a
detrimental effect on the price or volume of the security as far as the Fund is
concerned, it is also possible that the ability to participate in volume
transactions and to negotiate lower brokerage commissions will be beneficial to
the Fund.
 
  While the Adviser will be primarily responsible for the placement of the
Fund's business, the policies and practices in this regard must be consistent
with the foregoing and will at all times be subject to review by the trustees of
the Trust, of which the Fund is a separate series.
 
  The trustees have adopted certain policies incorporating the standards of Rule
17e-1 issued by the SEC under the 1940 Act which requires that the commissions
paid to the Distributor and other affiliates of the Fund must be reasonable and
fair compared to the commissions, fees or other remuneration received or to be
 
                                      B-31
<PAGE>   778
 
received by other brokers in connection with comparable transactions involving
similar securities during a comparable period of time. The rule and procedures
also contain review requirements and require the Adviser to furnish reports to
the trustees and to maintain records in connection with such reviews. After
consideration of all factors deemed relevant, the Trustees will consider from
time to time whether the advisory fee for the Fund will be reduced by all or a
portion of the brokerage commission given to affiliated brokers.
 
  State securities laws may differ from the interpretations of federal law
expressed herein, and banks and financial institutions may be required to
register as dealers pursuant to state law.
 
                             TAX STATUS OF THE FUND
 
   
  The Trust and any of its series, including the Fund, will be treated as
separate corporations for federal income tax purposes. The Fund intends to
qualify each year and to elect to be treated as a regulated investment company
under the Code. If the Fund so qualifies and distributes each year to its
shareholders at least 90% of its net investment income (including tax-exempt
interest, taxable income and net short-term capital gain, but not net capital
gains, which are the excess of long-term capital gains over net short-term
capital losses) in each year, it will not be required to pay federal income
taxes on any income distributed to shareholders. The Fund intends to distribute
at least the minimum amount of net investment income necessary to satisfy the
90% distribution requirement. The Fund will not be subject to federal income tax
on any net capital gains distributed to shareholders.
    
 
   
  The table below illustrates approximate equivalent taxable and tax-free yields
at the 1997 federal and New Jersey State gross income tax rates in effect on the
date of this Statement of Additional Information.
    
 
  The table shows, for example, that a couple with a taxable income of $90,000,
or a single individual with a taxable income of $55,000, whose investments earn
a 6% tax-free yield, would have to earn approximately an 8.82% taxable yield at
current federal and state income tax rates to receive the same benefit.

* Combined state and federal tax top marginal rate. The tax rate brackets listed
  are the 1997 federal income tax rate brackets. Because New Jersey's gross
  income tax utilizes a different set of rate brackets, more than one New Jersey
  gross income tax bracket may fall within a particular federal bracket. In
  those federal brackets where this is so, the highest marginal New Jersey gross
  income tax rate has been used for purposes of the table. This tends to
  slightly increase the taxable equivalent estimated current return shown above
  for lesser income amounts within certain federal brackets, but not by more
  than approximately 0.45% in the chart above.
    
 
                                THE DISTRIBUTOR
 
   
  The Distributor offers one of the industry's broadest lines of investments --
encompassing mutual funds, closed-end funds and unit investment trusts -- and is
currently the nation's 5th largest broker-sold mutual fund group according to
Strategic Insight, July 1995. VKAC manages or supervises more than $57 billion
in mutual funds, closed-end funds and unit investment trusts -- assets which
have been entrusted to VKAC in more than 2 million investor accounts. VKAC has
one of the largest research teams (outside of the rating agencies) in the
country, with more than 80 analysts devoted to various specializations. Each of
our high yield analysts, based either in San Francisco, Chicago, Houston or
Boston, has the responsibility to cover a specific

region of the country. This regional focus enables each high yield analyst to
provide more specialized coverage of the market and alert the portfolio manager
to issues of local importance.
    
 
   
  Shares of the Fund are offered continuously through Van Kampen American
Capital Distributors, Inc., One Parkview Plaza, Oakbrook Terrace, Illinois
60181. The Distributor is a wholly-owned subsidiary of MSAM Holdings II, Inc.
which, in turn, is a wholly-owned subsidiary of Morgan Stanley Group Inc. The
principal office of the Fund, the Adviser, the Distributor and VKAC is located
at One Parkview Plaza, Oakbrook Terrace, Illinois 60181.
    
 
   
  Morgan Stanley Group Inc. and various of its directly or indirectly owned
subsidiaries, including Morgan Stanley & Co. Incorporated, a registered
broker-dealer and investment adviser, and Morgan Stanley International, are
engaged in a wide range of financial services. Their principal businesses
include securities underwriting, distribution and trading; merger, acquisition,
restructuring and other corporate finance advisory activities; merchant banking;
stock brokerage and research services; asset management; trading of futures,
options, foreign exchange, commodities and swaps (involving foreign exchange,
commodities, indices and interest rates); real estate advice, financing and
investing; and global custody, securities clearance services and securities
lending.
    
 
   
  On February 5, 1997, Morgan Stanley Group Inc. and Dean Witter, Discover & Co.
announced that they had entered into an Agreement and Plan of Merger to form
Morgan Stanley, Dean Witter, Discover & Co. Subject to certain conditions being
met, it is currently anticipated that the transaction will close in mid-1997.
Thereafter, Van Kampen American Capital Asset Management, Inc. will be an
indirect subsidiary of Morgan Stanley, Dean Witter, Discover & Co.
    
 
   
  Dean Witter, Discover & Co. is a financial services company with three major
businesses; full service brokerage, credit services and asset management.
    
 
   
  Pursuant to a distribution agreement, the Distributor will purchase shares of
the Fund for resale to the public, either directly or through securities
dealers, and is obligated to purchase only those shares for which it has
received purchase orders. A discussion of how to purchase and redeem the Fund's
shares and how the Fund's shares are priced is contained in the Prospectus.
    
 
   
                         DISTRIBUTION AND SERVICE PLANS
    
 
   
  The Fund has adopted a distribution plan (the "Distribution Plan") with
respect to each class of its shares pursuant to Rule 12b-1 under the 1940 Act.
The Fund also has adopted a service plan (the "Service Plan") with respect to
each class of shares. The Distribution Plan and Service Plan sometimes are
referred to herein collectively as the "Plans". The Plans provide that the Fund
may spend a portion of the Fund's average daily net assets attributable to each
class of shares in connection with distribution of the respective class of
shares and in connection with the provision of ongoing services to shareholders
of such class, respectively. The Plans are being implemented through an
agreement (the "Distribution and Service Agreement") with the Distributor and
sub-agreements between the Distributor and members of the NASD acting as
securities dealers and NASD members or eligible non-members who are acting as
brokers or agents and similar agreements between the Fund and financial
intermediaries acting as brokers (collectively, "Selling Agreements") that may
provide for their customers or clients certain services or assistance, which may
include, but not be limited to, processing purchase and redemption transactions,
establishing and maintaining shareholder accounts regarding the Fund, and such
other services as may be agreed to from time to time and as may be permitted by
applicable statute, rule or regulation. Brokers, dealers and financial
intermediaries that have entered into sub-agreements with the Distributor and
sell shares of the Fund are referred to herein as "financial intermediaries."
    
 
  The Distributor must submit quarterly reports to the Board of Trustees of the
Trust, of which the Fund is a series, setting forth separately by class of
shares all amounts paid under the Plans and the purposes for which such
expenditures were made, together with such other information as from time to
time is reasonably requested by the Trustees. The Plans provide that they will
continue in full force and effect from year to year so long as such continuance
is specifically approved by a vote of the Trustees, and also by a vote of the
disinterested Trustees, cast in person at a meeting called for the purpose of
voting on the Plans. Each of the
 
                                      B-33
<PAGE>   780
 
Plans may not be amended to increase materially the amount to be spent for the
services described therein with respect to either class of shares without
approval by a vote of a majority of the outstanding voting shares of such class,
and all material amendments to either of the Plans must be approved by the
Trustees and also by the disinterested Trustees. Each of the Plans may be
terminated with respect to either class of shares at any time by a vote of a
majority of the disinterested Trustees or by a vote of a majority of the
outstanding voting shares of such class.
 
   
  For the fiscal year ended December 31, 1996, the Fund's aggregate expenses
under the Plans for Class A shares were $14,325 or 0.21% of the Class A shares'
average net assets. Such expenses were paid to reimburse the Distributor for
payments made to financial intermediaries for servicing Fund shareholders and
for administering the Plans. For the fiscal year ended December 31, 1996, the
Fund's aggregate expenses under the Plans for Class B shares were $82,603 or
0.96% of the Class B shares' average net assets. Such expenses were paid to
reimburse the Distributor for the following payments: $64,752 for commissions
and transaction fees paid to financial intermediaries in respect of sales of
Class B shares of the Fund and $17,851 for fees paid to financial intermediaries
for servicing Class B shareholders and administering the Plans. For the fiscal
year ended December 31, 1996, the Fund's aggregate expenses under the Plans for
Class C shares were $6,671 or 0.96% of the Class C shares' average net assets.
Such expenses were paid to reimburse the Distributor for the following payments:
$3,148 for commissions and transaction fees paid to financial intermediaries in
respect of sales of Class C shares of the Fund and $3,523 for fees paid to
financial intermediaries for servicing Class C shareholders and administering
the Plans.

issues in the portfolio. Materials may also mention how Van Kampen American
Capital believes the Fund compares relative to other Van Kampen American Capital
funds. Materials may also discuss the Dalbar Financial Services study from 1984
to 1994 which studied investor cash flow into and out of all types of mutual
funds. The ten year study found that investors who bought mutual fund shares and
held such shares outperformed investors who bought and sold. The Dalbar study
conclusions were consistent regardless of if shareholders purchased their funds
in direct or sales force distribution channels. The study showed that investors
working with a professional representative have tended over time to earn higher
returns than those who invested directly. The Fund will also be marketed on the
Internet.
 
  The Fund's yield quotation is determined on a monthly basis with respect to
the immediately preceding 30 day period, and yield is computed by dividing the
Fund's net investment income per share of a given class earned during such
period by the Fund's maximum offering price (including, with respect to the
Class A Shares, the maximum initial sales charge) per share of such class on the
last day of such period. The Fund's net investment income per share is
determined by taking the interest attributable to a given class of shares earned
by the Fund during the period, subtracting the expenses attributable to a given
class of shares accrued for the period (net of any reimbursements), and dividing
the result by the average daily number of the shares of each class outstanding
during the period that were entitled to receive dividends. The yield calculation
formula assumes net investment income is earned and reinvested at a constant
rate and annualized at the end of a six month period. Yield will be computed
separately for each class of shares. Class B Shares redeemed during the first
seven years after their issuance and Class C Shares redeemed during the first
year after their issuance may be subject to a contingent deferred sales charge
in a maximum amount equal to 4.00% and 1.00%, respectively, of the lesser of the
then current net asset value of the shares redeemed or their initial purchase
price from the Fund. Yield quotations do not reflect the imposition of a
contingent deferred sales
 
                                      B-34

charge, and if any such contingent deferred sales charge imposed at the time of
redemption were reflected, it would reduce the performance quoted.
 
  Tax-equivalent yield demonstrates the taxable yield required to produce an
after-tax yield equivalent to that of the Fund's yield. The Fund's
tax-equivalent yield quotation for a 30 day period as described above is
computed by dividing that portion of the yield of the Fund (as computed above)
which is tax-exempt by a percentage equal to 100% minus a stated percentage
income tax rate and adding the result to that portion of the Fund's yield, if
any, that is not tax-exempt.
 
  The Fund calculates average compounded total return by determining the
redemption value (less any applicable contingent deferred sales charge) at the
end of specified periods (after adding back all dividends and other
distributions made during the period) of a $1,000 investment in a given class of
shares of the Fund (less the maximum sales charge, if any) at the beginning of
the period, annualizing the increase or decrease over the specified period with
respect to such initial investment and expressing the result as a percentage.
Average compounded total return will be computed separately for each class of
shares.
 
  Total return figures utilized by the Fund are based on historical performance
and are not intended to indicate future performance. Total return and net asset
value per share of a given class can be expected to fluctuate over time, and
accordingly upon redemption a shareholder's shares may be worth more or less
than their original cost.
 
  The Fund may, in supplemental sales literature, advertise non-standardized
total return figures representing the cumulative, non-annualized total return of
each class of shares of the Fund from a given date to a subsequent given date.
Cumulative non-standardized total return is calculated by measuring the value of
an initial investment in a given class of shares of the Fund at a given time,
deducting the maximum initial sales charge, if any, determining the value of all
subsequent reinvested distributions, and dividing the net change in the value of
the investment as of the end of the period by the amount of the initial
investment and expressing the result as a percentage. Non-standardized total
return will be calculated separately for each class of shares. Non-standardized
total return calculations do not reflect the imposition of a contingent deferred
sales charge, and if any such contingent deferred sales charge with respect to
the CDSC imposed at the time of redemption were reflected, it would reduce the
performance quoted.

       SPECIAL CONSIDERATIONS RELATING TO NEW JERSEY MUNICIPAL SECURITIES
 
   
  As described in the Prospectus, except during temporary periods, the Fund will
invest substantially all of its assets in New Jersey municipal securities. In
addition, the specific New Jersey municipal securities in which the Fund will
invest will change from time to time. The Fund is therefore susceptible to
political, economic, regulatory or other factors affecting issuers of New Jersey
municipal securities. The following information constitutes only a brief summary
of a number of the complex factors which may impact issuers of New Jersey
municipal securities and does not purport to be a complete or exhaustive
description of all adverse conditions to which issuers of New Jersey municipal
securities may be subject. Such information is derived from the preliminary
official statement utilized in connection with the issuance of the $351,595,000
New Jersey Transit Corporation Capital Grant Anticipation Notes, Series 1997 A,
dated April 16, 1997, except for the Municipal Finance section, which is derived
from the official statement utilized in connection with the issuance of the
$714,340,000 New Jersey Transportation Trust Fund Authority Transportation
System Bonds, 1996 Series B, dated October 15, 1996. Such information has not
been independently verified by the Fund and the Fund assumes no responsibility
for the completeness or accuracy of such information. Additionally, many
factors, including national, economic, social and environmental policies and
conditions, which are not within the control of such issuers, could have an
adverse impact on the financial condition of such issuers. The Fund cannot
predict whether or to what extent such factors or other factors may affect the
issuers of New Jersey municipal securities, the market value or marketability of
such securities or the ability of the respective issuers of such securities
acquired by the Fund to pay interest on or principal of such securities. The
creditworthiness of obligations issued by local New Jersey issuers may be
unrelated to the creditworthiness of obligations issued by the State of New
Jersey and there is no responsibility on the part of the State of New Jersey to
make payments on such local obligations. There may be specific factors that are
applicable in connection with investment in the obligations of particular
issuers located within New Jersey, and it is possible the Fund will invest in
obligations of particular issuers as to which such specific factors are
applicable. However, the information set forth below is intended only as a
general summary and not as a discussion of any specific factors that may affect
any particular issuer of New Jersey municipal securities.
    
 
  The portfolio of the Fund may include municipal securities issued by the State
of New Jersey (the "State"), by its various public bodies (the "Agencies")
and/or by other entities located within the State.
 
The State and Its Economy
 
   
  New Jersey is the ninth largest state in population and the fifth smallest in
land area. With an average of 1,071 persons per square mile, it is the most
densely populated of all the states. New Jersey is located at the center of the
megalopolis which extends from Boston to Washington, and which includes over
one-fifth of the country's population. The extensive facilities of the Port
Authority of New York and New Jersey, the Delaware River Port Authority and the
South Jersey Port Corporation across the Delaware River from Philadelphia
augment the air, land and water transportation complex which has influenced much
of the State's economy. This central location in the northeastern corridor, the
transportation and port facilities and proximity to New York City make the State
an attractive location for corporate headquarters and international business
offices. A number of Fortune Magazine's top 500 companies maintain headquarters
or major facilities in New Jersey, and many foreign-owned firms have located
facilities in the State.
    
 
  The State's economic base is diversified, consisting of a variety of
manufacturing, construction and service industries, supplemented by rural areas
with selective commercial agriculture. New Jersey has the Atlantic seashore on
the east and lakes and mountains in the north and northwest, which provide
recreation for residents as well as for out-of-state visitors. In 1976, voters
approved casino gambling for Atlantic City, which has again become an important
State tourist attraction.
 
   
  New Jersey's population grew rapidly in the years following World War II,
before slowing to an annual rate of 0.27 percent in the 1970s. Between 1980 and
1990, the annual growth rose to 0.49 percent and between 1990 and 1995,
accelerated to .52%. While this rate of growth is less than that for the United
States, it
    
 
                                      B-37
<PAGE>   784
 
   
compares favorably with other Middle Atlantic States. New York has shown a 0.15
percent annual rate of increase since 1990 and Pennsylvania's population has
increased 0.30 percent per year.
    
 
  The small increase in the State's total population during the past quarter
century masks the redistribution of population within the State. There has been
a significant shift from the northeastern industrial areas toward the four
coastal counties (Cape May, Atlantic, Ocean and Monmouth) and toward the central
New Jersey counties of Hunterdon, Somerset and Middlesex.
 
   
  Total personal income in New Jersey stood at $224.5 billion for 1994 and
$237.2 billion for 1995, an increase of 5.6 percent. Nationally, total personal
income grew by 6.2 percent between 1994 and 1995, while in New York and
Pennsylvania it grew by 5.3 percent and 5.5 percent, respectively. Based on 1973
levels, the personal income index in 1995 stood at 539.2 for New Jersey, 464.0
for New York and 469.4 for Pennsylvania. The United States index stood at 558.3
(1973 = 100).
    
 
   
  Historically, New Jersey's average per capita income has been well above the
national average. The differential narrowed during the 1970s, widened in the
1980s, and has narrowed slightly in the 1990s. In 1995, the State ranked second
among all states in per capita personal income ($29,848). It ranked higher than
New York, with per capita income of $27,678 and Pennsylvania with $23,558. Only
Connecticut, with $31,776, exceeded New Jersey's $29,848.
    
 
   
  After enjoying a boom during the mid-1980s, New Jersey as well as the rest of
the Northeast slipped into a slowdown well before the onset of the national
recession which officially began in July 1990 (according to the National Bureau
of Economic Research). By the beginning of the national recession of 1990-1991,
construction activity had already been declining in New Jersey for nearly two
years, growth had tapered off markedly in the service sectors and the long-term
downward trend of factory employment had accelerated, partly because of a
leveling off of industrial demand nationally. The onset of recession caused an
acceleration of New Jersey's job losses in construction and manufacturing, as
well as an employment downturn in such previously growing sectors as wholesale
trade, retail trade, finance, utilities, trucking and warehousing. The net
effect was a decline in the State's total nonfarm wage and salary employment
from a peak of 3,689,800 in 1989 to a low of 3,457,900 in 1992. This loss was
followed by an employment gain of 200,700 from May 1992 to August 1996, a
recovery of 77% of the jobs lost during the recession. More than two-thirds of
this number, nearly 138,000 jobs, were recovered in the 31 month period from
January 1994 to August 1996.
    
 
   
  Reflecting the downturn, the rate of unemployment in the State rose from a low
of 3.6 percent during the first quarter of 1989 to a recessionary peak of 8.5%
during 1992. Since then, the unemployment rate fell to an average of 6.4% in
1995 and 6.1% for the four month period from May 1996 through August 1996.
    
 
   
  For the recovery period as a whole, May 1992 to August, 1996,
service-producing employment in New Jersey has expanded by 228,500 jobs. Hiring
has been reported by food stores, auto dealers, wholesale distributors, trucking
and warehousing firms, utilities, business and engineering/management service
firms, hotels/hotel-casinos, social service agencies and health care providers
other than hospitals. Employment growth was particularly strong in business
services and its personnel supply component with increases of 17,500 and 8,100,
respectively, in the 12-month period ending August 1996.
    
 
   
  In the manufacturing sector, employment losses slowed between 1992 and 1994.
After an average annual job loss of 33,500 from 1989 through 1992, New Jersey's
factory job losses fell to 13,300 during 1993 and 7,300 during 1994. During
1995, however, manufacturing job losses increased slightly to 9,100, reflecting
a slowdown in national manufacturing production activity. While experiencing
growth in the number of production workers in 1994, the number declined in 1995
at the same time that managerial and office staff were also reduced as part of
nationwide downsizing. Through August 1996 layoffs of white collar workers and
corporate downsizing appear to be abating.
    
 
   
  Conditions have slowly improved in the construction industry, where employment
has risen by 15,600 since its low in May 1992. Between 1992 and 1995, this
sector's hiring rebound was driven primarily by increased homebuilding and
nonresidential projects. During 1996, public works projects and homebuilding
became the growth segments while nonresidential construction lessened.
    
 
                                      B-38
<PAGE>   785
 
   
  Nonresidential construction activity, as measured by contract awards, grew by
9.7% in 1993, 19.6% in 1994 and 3.0% in 1995. More recently, nonresidential
building construction contracts fell by 20.5% in the first eight months of 1996.
This decline is largely attributable to an abundance of large, one-time contract
awards during 1995, including a $202.9 million contract for the construction of
a state prison.
    
 
   
  Residential construction contracts through August 1996, despite monthly
fluctuations, increased by 1.4% for the first eight months of 1996 as compared
to the first eight months of 1995 ($1,502 million and $1,481 million,
respectively). Nonbuilding or infrastructure construction rose robustly by 17.8%
during this period. Despite these increases, total construction contracts
declined by 3.9% when comparing the first eight months of 1995 and 1996.
    
 
   
  Improvements in overall employment opportunities and the economy in general
have led to increased consumer spending during the recovery. While overall
retail sales in New Jersey grew by only 1.6% during 1993, they performed much
better in 1994, advancing by 7.8% which exceeded the 7.5% growth registered
nationwide. During 1995, especially the winter months, consumer confidence and
actual consumer spending moderated both nationally and in the State. For all of
1995, retail sales in New Jersey grew by 2.3%. Retail sales regained momentum in
1996 and have been on a moderately upward trend, rising to an annual rate of
$76.5 billion through June. The State's pickup in growth after a
blizzard-related January decline resulted in sales growth of 4.2% when comparing
the first six months of 1995 with those of 1996. The rising trend in retail
sales has translated into steady increases in retail trade jobs (both full-time
and part-time) with a rise in retail employment from December 1995 to August
1996 of 6,900 jobs.
    
 
   
  Total new vehicle registrations (new passenger cars and light trucks and vans)
rose robustly in 1993 by more than 18%, and in 1994 by 5.8%, but declined by
4.4% in 1995. Through July 1996 however, total new vehicle registrations rose by
3.5% compared to the same time period in 1995.
    
 
   
  Unemployment in the State through August 1996 has been receding. According to
the U.S. Bureau of Labor Statistics, the jobless rate dropped from 7.5% in 1993
to 6.8% in 1994 and to 6.4% in 1995. Subsequently, it has dropped to 6.1% for
the four-month period from May 1996 through August 1996.
    
 
   
  The insured unemployment rate, i.e., the number of individuals claiming
benefits as a percentage of the number of workers covered by unemployment
insurance, declined from 3.9% during calendar years 1991 and 1992 to 3.3% during
1993 and then averaged 3.2% throughout 1994, 1995 and the first six months of
1996. As of August 1, 1996, the State's unemployment insurance trust fund
balance stood at $2.1 billion.
    
 
ATLANTIC CITY AND LEGALIZED GAMBLING
 
   
  Legalized casino gambling was introduced into Atlantic City by the enactment
of the Casino Control Act on June 2, 1977 following a public referendum which
passed by a 3-to-2 margin in November 1976. The framers of the legislation
intended legalized gambling to foster the redevelopment of the tourism, resort
and convention industries in Atlantic City, to provide new jobs and to generate
added tax revenues for assistance programs for the elderly and disabled. Since
passage of that legislation, thirteen hotel/casinos have opened in Atlantic
City. However, on May 22, 1989, Elsinore's Atlantis Casino Hotel discontinued
its casino operations due to its severe financial difficulties. In May 1996,
Trump Plaza reopened the former Atlantis Casino Hotel Facility as Trump's World
Fair and integrated it into its existing facility.
    
 
   
  For the year ended December 31, 1995, nine of the twelve operating casinos
reported a profit. The industry as a whole reported net income of $147.1 million
for the year, reflecting a $115.7 million increase from the net income of $31.4
million reported for the prior comparable period. This industry net income
reflects strong profits at Harrah's Marina ($43.6) million, Bally's Park Place
($40.5 million) and Caesar's ($32.7 million) which combined to account for 79.4%
of industry profits. Meanwhile, Trump Taj Mahal and Trump's Castle reported
losses of $26.6 million and $11.2 million, respectively.
    
 
   
  For the year ended December 31, 1995 and the eight months ended August 31,
1996, the casino industry reported "Win" of $3.7 billion and $2.6 billion,
respectively. "Win" represents the amount a casino wins at the slot machines and
table games before operating expenses and taxes are deducted.
    
 
                                      B-39
<PAGE>   786
 
   
  For the year ended December 31, 1995 and the eight months ended August 31,
1996, the State collected revenue taxes for programs to assist the elderly and
disabled of $298.1 million and $205.7 million, respectively. From May 20, 1978,
the date the first casino opened, through August 31, 1996, the industry has paid
a total of $3.4 billion to the State for these programs. As of August 31, 1996,
the Casino Revenue Fund has earned $117.5 million in interest.
    
 
   
  In 1995 there were 44,700 jobs in the hotel/casinos; total employment in the
Atlantic County metropolitan statistical area has grown from 89,000 persons in
1975 to 173,600 in 1995. Tourism has also prospered. The number of visitors to
Atlantic City increased from 7.0 million for 1978 to 33.3 million for 1995.
    
 
  The gaming industry has also provided substantial revenue for municipal,
county and school governments through real estate taxes and payment of the
luxury tax which the State has authorized and which is applied to hotel tax and
amusement revenues.
 
NEW JERSEY STATE LOTTERY FINANCIAL DATA
 
   
  The New Jersey State Lottery was created as a major source of revenue for
State education and institutions. As of June 30, 1996, the Lottery has generated
over $19.7 billion in gross revenues, paid $9.7 billion in prizes and
contributed $8.24 billion to the State.
    
 
   
  Higher Education programs have received approximately $2.252 billion in
Lottery funds. For elementary and secondary education, the State Department of
Education has received approximately $1.730 billion. State institutions have
received a total of $4.254 billion in Lottery monies.
    
 
   
  In Fiscal Year 1996, gross revenues totalled $1.62 billion, of which 50.85%
was returned in prizes, 40.92 percent went to State education and institutions,
6.94% was paid to sales agents and ticket vendors and 1.29% covered lottery
operational and promotional expenses.
    
 
                                 STATE FINANCES
 
  The Director of the Division of Budget and Accounting in the Department of
Treasury of the State (the "Budget Director") prescribes and approves the
accounting policies of the State and directs their implementation.
 
NEW JERSEY'S ACCOUNTING SYSTEM
 
  The State prepares its financial statements on a "modified accrual" basis
utilizing the fund method of accounting. The National Council on Governmental
Accounting in its publication entitled Statement I. -- Governmental Accounting
and Financial Reporting Principles defines a fund as a fiscal and accounting
entity with a self-balancing set of accounts recording cash and other financial
resources together with all related liabilities and residual equities or
balances, and changes therein, which are segregated for the purpose of carrying
on specific activities or attaining certain objectives in accordance with
special regulations, restrictions or limitations. The State's financial
statements reflect financial reporting practices in accordance with that
definition. Accordingly, the State prepares separate statements for the General
Fund, Special Revenue Funds, Debt Service Funds, Capital Project Funds, Trust
and Agency Funds, Component Units--Authorities Funds, College and University
Funds, General Fixed Asset Account Group and its General Long-Term Debt Account
Group, and its component units.
 
  The General Fund is the fund into which all State revenues not otherwise
restricted by statute are deposited and from which appropriations are made. The
largest part of the total financial operations of the State is accounted for in
the General Fund. Revenues received from taxes and unrestricted by statute, most
federal revenue and certain miscellaneous revenue items are recorded in the
General Fund. The appropriations acts provide the basic framework for the
operation of the General Fund.
 
  Special Revenue Funds are used to account for resources legally restricted to
expenditure for specified purposes. Special Revenue Funds include the Casino
Control Fund, the Casino Revenue Fund, the Gubernatorial Elections Fund and the
Property Tax Relief Fund. Debt Service Funds are used to account for the
accumulation of resources for, and the payment of, principal and redemption

interest on general obligation bonds. Capital Project Funds are used to account
for financial resources to be used for the acquisition or construction of major
State capital facilities. Trust and Agency Funds are used to account for assets
held in a trust capacity or as an agent for individuals, private organizations,
other governments and/or other funds. The General Fixed Asset Account Group
accounts for the State's fixed assets acquired or constructed for general
governmental purposes. The General Long-Term Debt Account Group accounts for the
unmatured general long-term liabilities of the State.
 
  The Property Tax Relief Fund, the largest of the Special Revenue Funds, is
used to account for revenues from the New Jersey Gross Income Tax. Revenues
realized from the Gross Income Tax are dedicated by the State Constitution. All
receipts from taxes levied on personal income of individuals, estates and trusts
must be appropriated exclusively for the purpose of reducing or offsetting
property taxes.
 
New Jersey's Budget and Appropriation System
 
   
  The State operates on a fiscal year beginning July 1 and ending June 30. For
example, "Fiscal Year 1998" refers to the State's fiscal year beginning July 1,
1997 and ending June 30, 1998.
    
 
  Pursuant to Article VIII, Section II, par. 2 of the State Constitution, no
money may be drawn from the State Treasury except for appropriations made by
law. In addition, all monies for the support of State government and all other
State purposes, as far as can be ascertained or reasonably foreseen, must be
provided for in one general appropriation law covering one and the same fiscal
year. No general appropriations law or other law appropriating money for any
State purpose shall be enacted if the amount of money appropriated therein,
together with all other prior appropriations made for the same fiscal year,
exceeds the total amount of revenue on hand and anticipated to be available for
such fiscal year, as certified by the Governor.
 
  In addition to the Constitutional provisions, the New Jersey Statutes contain
provisions concerning the budget and appropriation system. On or before October
1 in each year, each Department, Board, Commission, officer, or other Agency of
the State must file with the Budget Director a request for appropriation or
permission to spend specifying all expenditures proposed to be made by such
spending agency during the following fiscal year. The Budget Director then
examines each request and determines the necessity or advisability of the
appropriation request. The Budget Director may hold hearings, open to the
public, during the months of October, November and December and reviews the
budget requests with the agency heads. On or before December 31 of each year or
such other time as the Governor may request, after review and examination, the
Budget Director submits the requests, together with her findings, comments and
recommendations, to the Governor. It is then the responsibility of the Governor
to examine and consider all requests and formulate her budget recommendations.
 
  The Governor's budget message (the "Governor's Budget Message") is then
transmitted on or before the third Tuesday following the first meeting of the
State Legislature in each year, except in the year when a Governor is
inaugurated, when it must be transmitted on or before February 15. The
Governor's Budget Message must embody the proposed complete financial program of
the State government for the next ensuing fiscal year and must set forth in
detail each source of anticipated revenue and the purposes of recommended
expenditures for each spending agency. After a process of legislative committee
review, the budget, in the form of an appropriations bill, must be approved by
the Senate and Assembly and must be submitted to the Governor for review. Upon
such submissions, the Governor may approve the bill, revise the estimate of
anticipated revenues contained therein, delete or reduce appropriation items
contained in the bill through the exercise of her line-item veto power, or veto
the bill in its entirety. Like any gubernatorial veto, such action may be
reversed by a two-thirds vote of each House of the State Legislature. In
addition to anticipated revenues, the appropriations act also provides for the
appropriation of non-budgeted revenue to the extent such revenue may be received
and permits the corresponding increase of appropriation balances from which
expenditures may be made.

                       FINANCIAL RESULTS AND PROJECTIONS
 
AUDIT REPORTS
 
  The State Auditor is directed by statute to "examine and post-audit all the
accounts, reports and statements and make independent verifications of all
assets, liabilities, revenues and expenditures" of the State and its agencies.
The audit reports containing the opinion of the State Auditor are available for
examination and review upon request to the State Treasurer.
 
   
FISCAL YEARS 1997 AND 1998 REVENUE ESTIMATES
    
 
   
  Sales and Use Tax. The revised estimate as shown in the Governor's Fiscal Year
1998 Budget Message forecasts Sales and Use tax collections for Fiscal Year 1997
as $4,385.0 million, a 1.5% increase from the Fiscal Year 1996 revenue. The
Fiscal Year 1998 estimate of $4,557.0 million, is a 3.9% increase from the
Fiscal Year 1997 estimate.
    
 
   
  Gross Income Tax. The revised estimate as shown in the Governor's Fiscal Year
1998 Budget Message forecasts Gross Income Tax collections for Fiscal Year 1997
of $4,710.0 million, a 0.5% increase from Fiscal Year 1996 revenue. The Fiscal
Year 1998 estimate of $4,830.0 million, is a 2.5% increase from the Fiscal Year
1997 estimate. Included in the Fiscal Year 1998 estimate is the enactment of a
property tax deduction, to be phased in over a three-year period, permitting a
deduction by resident taxpayers against gross income tax of a percentage of
their property taxes.
    
 
   
  Corporation Business Tax. The revised estimate as shown in the Governor's
Fiscal Year 1998 Budget Message forecasts Corporation Business Tax collection
for Fiscal Year 1997 as $1,120.8 million, a 4.3% decrease from Fiscal Year 1996
revenue. The Fiscal Year 1998 forecast as shown in the Governor's Fiscal Year
1998 Budget Message of $1,134.6 million, is a 1.2% increase from the Fiscal Year
1997 estimate.
    
 
  General Considerations. Estimated receipts from State taxes and revenues,
including the three principal taxes set forth above, are forecasts based on the
best information available at the time of such forecasts. Changes in economic
activity in the State and the nation, consumption of durable goods, corporate
financial performance and other factors that are difficult to predict may result
in actual collections being more or less than forecasted.
 
  Should revenues be less than the amount anticipated in the budget for a fiscal
year, the Governor may, pursuant to statutory authority, prevent any expenditure
under any appropriation. There are additional means by which the Governor may
ensure that the State is operated efficiently and does not incur a deficit. No
supplemental appropriation may be enacted after adoption of an appropriations
act except where there are sufficient revenues on hand or anticipated, as
certified by the Governor, to meet such appropriation. In the past when actual
revenues have been less than the amount anticipated in the budget, the Governor
has exercised her plenary powers leading to, among other actions, implementation
of a hiring freeze for all State departments and the discontinuation of programs
for which appropriations were budgeted but not yet spent.
 
  Pending Litigation. In connection with the Fiscal Year 1996 budget, certain
unions and individual plaintiffs have filed a lawsuit concerning the funding of
certain retirement systems. See "LITIGATION -- New Jersey Education Association
et al. v. State of New Jersey et al."
 
   
  The State has made appropriations for principal and interest payments for
general obligation bonds for Fiscal Years 1993 through 1996 in the amounts of
$444.3 million, $119.9 million, $103.6 million and $466.3 million, respectively.
The Fiscal Year 1997 Appropriations Act includes an appropriation in the amount
of $446.9 million for principal and interest payments for general obligation
bonds.
    
 
   
PROGRAMS FUNDED UNDER FISCAL YEAR 1997 ADJUSTED APPROPRIATIONS
    
 
   
  Of the $16,217.7 million appropriated in Fiscal Year 1997 from the General
Fund, the Property Tax Relief Fund, the Casino Control Fund, the Casino Revenue
Fund and the Gubernatorial Elections Fund, $6,384.7 million (39.4%) is
appropriated for State Aid to Local Governments, $3,858 million (23.8%) is
    
 
                                      B-42
<PAGE>   789
 
   
appropriated for Grants-in-Aid, $5,154 million (31.6%) for Direct State
Services, $446.9 million (2.7%) for Debt Service on State general obligation
bonds and $374.1 million (2.3%) for Capital Construction.
    
 
STATE AID TO LOCAL GOVERNMENTS
 
   
  State Aid to Local Governments is the largest portion of Fiscal Year 1997
appropriations. In Fiscal Year 1997, $6,384.7 million of the State's
appropriations consist of funds which are distributed to municipalities,
counties and school districts. The largest State Aid appropriation, in the
amount of $4,851.4 million, is provided for local elementary and secondary
education programs. Appropriations to the Department of Community Affairs (DCA)
total $840.4 million in State Aid monies for Fiscal Year 1997. Appropriations to
the State Department of the Treasury total $206.1 million in State Aid monies
for Fiscal Year 1997. Other appropriations of State Aid in Fiscal Year 1997
include: welfare programs ($340.6 million); and aid to county mental hospitals
($76.0 million).
    
 
DIRECT STATE SERVICES
 
   
  The second largest portion of appropriations in Fiscal Year 1997 is applied to
Direct State Services: which supports the operation of State government's
sixteen departments, the Executive Office, several commissions, the State
Legislature and the Judiciary. In Fiscal Year 1997, appropriations for Direct
State Services aggregate to $5,154 million.
    
 
   
  $602.1 million is appropriated for programs administered by the Department of
Human Services. The Department of Labor is appropriated $55.5 million for the
administration of programs for workers compensation, unemployment and disability
insurance, manpower development and health safety inspection. The Department of
Health and Senior Services is appropriated $45.1 million for the prevention and
treatment of diseases, alcohol and drug abuse programs, regulation of health
care facilities and the uncompensated care program. $732.3 million is
appropriated for the support of nine State colleges, Rutgers University, the New
Jersey Institute of Technology and the University of Medicine and Dentistry of
New Jersey. $889.5 million is appropriated to the Department of Law and Public
Safety (excluding the Division of Juvenile Services) and the State Department of
Corrections. $159.4 million is appropriated to the Department of Transportation
for the various programs it administers, such as the maintenance and improvement
of the State highway system and the registration and regulation of motor
vehicles and licensed drivers. $179.9 million is appropriated to the Department
of Environmental Protection for the protection of air, land, water, forest,
wildlife and shellfish resources and for the provision of outdoor recreational
facilities.
    
 
GRANTS-IN-AID
 
   
  The third largest portion of appropriations in Fiscal Year 1997 is for
grants-in-aid. These represent payments to individuals or public or private
agencies for benefits to which a recipient is entitled to by law, or for the
provision of services on behalf of the State. The amount appropriated in Fiscal
Year 1997 for grants-in-aid is $3,858 million.
    
 
   
  $1,927.4 million is appropriated for programs administered by the Department
of Human Services. Of that amount, $1,304.1 million is for medical services
provided under the Medicaid program, $172.9 million is for community programs
for the developmentally disabled, $159.5 million is for community programs for
the mentally ill, $211.3 million is for grant programs administered by the
Division of Youth and Family Services, and $75.5 million is for welfare reform
and homeless services.
    
 
   
  $325 million is appropriated to the Department of the Treasury for the
Homestead Rebate program, which provides property tax relief to homeowners and
renters. $219.6 million is appropriated to the Department of Transportation for
bus and railroad subsidies.
    
 
Debt Service
 
  The primary method for State financing of capital projects is through the sale
of the general obligation bonds of the State. These bonds are backed by the full
faith and credit of the State. State tax revenues and certain other fees are
pledged to meet the principal payments, interest payments and if provided,
redemption
 
                                      B-43
<PAGE>   790
 
   
premium payments, if any, required to fully pay the bonds. The appropriation for
the debt service obligation on outstanding indebtedness is $446.9 million for
Fiscal Year 1997.
    
 
   
  For many years prior to 1991, both Moody's and S&P rated New Jersey general
obligation bonds "Aaa" and "AAA", respectively. On July 3, 1991, however, S&P
downgraded New Jersey general obligation bonds to "AA+." On August 26, 1992,
Moody's downgraded New Jersey general obligation bonds to "Aa1". The issuance of
the $526,800 State of New Jersey General Obligation Bonds Refunding Bonds
(Series E) and $270,000,000 State of New Jersey General Obligation Bonds
(Various Purposes) on May 1, 1996 was rated AA+ by S&P and Aa1 by Moody's.
Although impacted in general by the financial condition of the State, local
municipalities issuing New Jersey Municipal Obligations have credit ratings that
are determined with reference to the financial condition of such local
municipalities.
    
 
Capital Construction
 
   
  In addition to payments from bond proceeds, capital construction can also be
funded by appropriation of current revenues on a pay-as-you-go basis. In Fiscal
Year 1997, the amount appropriated to this purpose is $374.1 million.
    
 
  All appropriations for capital projects and all proposals for State bond
authorization are subject to the review and recommendation of the New Jersey
Commission on Capital Budgeting and Planning. This permanent commission was
established in November 1975, and is charged with the preparation of the State
Capital Improvement Plan, which contains proposals for State spending for
capital projects.
 
                       TAX AND REVENUE ANTICIPATION NOTES
 
   
  In Fiscal Year 1992, the State initiated a program under which it issued tax
and revenue anticipation notes to aid in providing effective cash flow
management to fund balances which occur in the collection and disbursement of
the General Fund and Property Tax Relief Fund revenues. There are presently $600
million of tax and revenue anticipation notes outstanding. These notes shall
mature on June 13, 1997.
    
 
  Such tax and revenue anticipation notes do not constitute a general obligation
of the State or a debt or liability within the meaning of the State
Constitution. Such notes constitute special obligations of the State payable
solely from moneys on deposit in the General Fund and the Property Tax Relief
Fund and legally available for such payment.
 
                        OTHER STATE RELATED OBLIGATIONS
 
LEASE FINANCING
 
  The State has entered into a number of leases relating to the financing of
certain real property and equipment. The State leases the Richard J. Hughes
Justice Complex in Trenton from the Mercer County Improvement Authority (the
"MCIA"). On August 8, 1991 the MCIA defeased outstanding bonds originally issued
to finance construction of the Richard J. Hughes Justice Complex through the
issuance of custody receipts (the "Custody Receipts") in the aggregate principal
amount of $98,760,000. The rental is sufficient to cover the debt service on the
MCIA's Custody Receipts. The State's obligation to pay the rentals is subject to
appropriations being made by the State Legislature.
 
   
  The State has also entered into a lease agreement, as lessee, with the New
Jersey Economic Development Authority, (the "EDA") as lessor to lease (i) office
buildings that house the New Jersey Division of Motor Vehicles, New Jersey
Network (the State's public television station), a branch of the United States
Postal Service and a parking facility and (ii) to lease approximately 13 acres
of real property and certain infrastructure improvements thereon located in the
City of Newark.
    
 
   
  Beginning in April 1984, the State, acting through the Director of the
Division of Purchase and Property, entered into a series of lease purchase
agreements which provide for the acquisition of equipment, services and real
property to be used by various departments and agencies of the State. To date,
the State has entered into eleven lease purchase agreements which have resulted
in the issuance of Certificates of Participation totaling
    
 
                                      B-44
<PAGE>   791
 
$749,350,000. A Certificate of Participation evidences a proportionate interest
of the owner thereof in the lease payments to be made by the State under the
terms of the agreement. The agreements relating to these transactions provide
for semiannual rental payments. The State's obligation to pay rentals due under
these leases is subject to annual appropriations being made by the State
Legislature. The majority of proceeds from these transactions have been or will
be used to acquire equipment and services for the State and its agencies. The
State intends to continue to use this financing technique for a substantial
portion of its future equipment requirements.
 
   
MARKET TRANSITION FACILITY
    
 
  Legislation enacted in June 1994 authorizes the EDA to issue bonds to pay the
current and anticipated liabilities and expenses of the Market Transition
Facility, which issued private passenger automobile insurance policies for
drivers who could not be insured by private insurance companies on a voluntary
basis. On July 26, 1994 the EDA issued $705,270,000 aggregate principal amount
of Market Transition Facility Senior Lien Revenue Bonds, Series 1994A. The EDA
and State Treasury have entered into an agreement which provides for the payment
to the EDA of amounts on deposit in the DMV Surcharge Fund to pay debt service
on the bonds. Such payments are subject to and dependent upon appropriations
being made by the State Legislature.
 
EDUCATIONAL FACILITIES AUTHORITY
 
  Legislation enacted in 1993 authorizes the Educational Facilities Authority
(the "EFA") to issue bonds to finance the purchase of equipment to be leased to
institutions of higher learning. On August 17, 1994 the EFA issued $100,000,000
aggregate principal amount of Higher Education Leasing Fund Program bonds. The
EFA and the State Treasurer have entered into an agreement which provides to the
EFA amounts required to pay debt service on the bonds. Such payments are subject
to and dependent upon appropriations being made by the State Legislature.
 
   
  Other legislation enacted in 1993 created the Higher Education Facilities
Trust Fund and authorized its funding by the issuance of bonds to make grants to
New Jersey's public and private institutions of higher education for the
development, construction and improvement of instructional, laboratory,
communication and research facilities. The legislation limits the total
outstanding amount of bonds to be issued to $220,000,000. On November 29, 1995
the EFA issued $220,000,000 aggregate principal amount of Higher Education
Facilities Trust Fund Bonds, Series 1995A. These bonds are secured by payments
to be made to the EFA by the State, which payments are subject to and dependent
upon appropriations being made by the State Legislature.
    
 
STATE SUPPORTED SCHOOL AND COUNTY COLLEGE BONDS
 
   
  Legislation provides for future appropriations for State Aid to local school
districts equal to debt service on a maximum principal amount of $280,000,000 of
bonds issued by such local school districts for construction and renovation of
school facilities and for State Aid to counties equal to debt service on up to
$80,000,000 of bonds issued by counties for construction of county college
facilities. The State Legislature is not legally bound to make such future
appropriations, but has done so to date on all outstanding obligations issued
under these laws. As of June 30, 1996, the maximum amount of $280,000,000 school
district bonds has been approved for State support. Bonds or notes in the amount
of $274,074,000 have been issued by local school districts, of which
$246,576,172 have been retired and $27,497,831 are still outstanding. As of June
30, 1996, $44,316,818 of county college bonds or notes are outstanding. In
addition to these acts, there is legislation which establishes a school bond
reserve within the constitutionally dedicated fund for the Support of Free
Public Schools (see "MUNICIPAL FINANCE -- New Jersey School Bond Reserve Act").
    
 
"MORAL OBLIGATION" FINANCING
 
  The authorizing legislation for certain State entities provides for specific
budgetary procedures with respect to certain obligations issued by such
entities. Pursuant to such legislation, a designated official is required to
certify any deficiency in a debt service reserve fund maintained to meet
payments of principal of and interest on the obligations, and a State
appropriation in the amount of the deficiency is to be made. However, the State
 
                                      B-45
<PAGE>   792
 
Legislature is not legally bound to make such an appropriation. Bonds issued
pursuant to authorizing legislation of this type are sometimes referred to as
"moral obligation" bonds. There is no statutory limitation on the amount of
"moral obligation" bonds which may be issued by eligible State entities.
 
NEW JERSEY SPORTS AND EXPOSITION AUTHORITY
 
  On March 2, 1992, the New Jersey Sports and Exposition Authority (the "Sports
Authority") issued $147,490,000 in State guaranteed bonds and defeased all
previously outstanding State guaranteed bonds of the Sports Authority. The State
believes that the revenue of the Sports Authority will be sufficient to provide
for the payment of debt service on these obligations without recourse to the
State's guarantee.
 
   
  Legislation enacted in 1992 by the State authorizes the Sports Authority to
issue bonds for various purposes payable from State appropriations. Pursuant to
this legislation, the Sports Authority and the State Treasurer have entered into
an agreement (the "State Contract") pursuant to which the Sports Authority will
undertake certain projects, including the refunding of certain outstanding bonds
of the Sports Authority, and the State Treasurer will credit to the Sports
Authority Fund amounts from the General Fund sufficient to pay debt service and
other costs related to the bonds. The payment of all amounts under the State
Contract is subject to and dependent upon appropriations being made by the State
Legislature. As of June 30, 1996 there are approximately $463,310,000 aggregate
principal amount of Sports Authority bonds currently outstanding the debt
service on which is payable from amounts credited to the Sports Authority Fund
pursuant to the State Contract.
    
 
NEW JERSEY TRANSPORTATION TRUST FUND AUTHORITY
 
   
  In July 1984, the State created the New Jersey Transportation Trust Fund
Authority (the "TTFA"), an instrumentality of the State organized and existing
under the New Jersey Transportation Trust Fund Authority Act of 1984, as amended
(the "TTFA Act") for the purpose of funding a portion of the State's share of
the cost of improvements to the State's transportation system. Pursuant to the
TTFA Act, the TTFA, the State Treasurer and the Commissioner of Transportation
executed a contract (the "Contract") which provides for the payment of certain
amounts to the TTFA. The payment of all such amounts is subject to and dependent
upon appropriations being made by the State Legislature and there is no legal
obligation that the Legislature make such appropriation. On May 30, 1995, the
State Legislature amended the New Jersey Transportation Trust Fund Act of 1984
to provide, among other things, for (i) the issuance of debt in an aggregate
principal amount in excess of the statutory debt limitation in effect prior to
the enactment of the 1995 Amendments, (ii) an increase in the amount of revenues
available to the TTFA and (iii) broadening the scope of transportation projects.
    
 
  Pursuant to the TTFA Act, the principal amount of the TTFA's bonds, notes or
other obligations which may be issued in any fiscal year generally may not
exceed $700 million plus amounts carried over from prior fiscal years. These
bonds are special obligations of the TTFA payable from the payments made by the
State pursuant to the Contract.
 
ECONOMIC RECOVERY FUND BONDS
 
  Legislation enacted during 1992 by the State authorizes the EDA to issue bonds
for various economic development purposes. Pursuant to that legislation, EDA and
the State Treasurer have entered into an agreement (the "ERF Contract") through
which EDA has agreed to undertake the financing of certain projects and the
State Treasurer has agreed to credit to the Economic Recovery Fund from the
General Fund amounts equivalent to payments due to the State under an agreement
with the Port Authority of New York and New Jersey. The payment of all amounts
under the ERF Contract is subject to and dependent upon appropriations being
made by the State Legislature.
 
                                      B-46
<PAGE>   793
 
                               MUNICIPAL FINANCE
 
  New Jersey's local finance system is regulated by various statutes. Regulatory
and remedial statutes are enforced by the Division of Local Government Services
(the "Division") in the State Department of Community Affairs.
 
COUNTIES AND MUNICIPALITIES
 
  The Local Budget Law imposes specific budgetary procedures upon counties and
municipalities ("local units"). Every local unit must adopt an operating budget
which is balanced on a cash basis, and items of revenue and appropriation must
be examined by the Director of the Division (the "Director"). The accounts of
each local unit must be independently audited by a registered municipal
accountant. State law provides that budgets must be submitted in a form
promulgated by the Division and further provides for limitations on estimates of
tax collection and for reserves in the event of any shortfalls in collections by
the local unit. The Division reviews all municipal and county annual budgets
prior to adoption for compliance with the Local Budget Law. The Director is
empowered to require changes for compliance with law as a condition of approval;
to disapprove budgets not in accordance with law; and to prepare the budget of a
local unit, within the limits of the adopted budget of the previous year with
suitable adjustments for legal compliance, if the local unit fails to adopt a
budget in accordance with law.
 
  The Local Government Cap Law (the "Cap Law") generally limits the year-to-year
increase of the total appropriations of any municipality and the tax levy of any
county to either 5 percent or an index rate determined annually by the Director,
whichever is less. However, where the index percentage rate exceeds 5 percent,
the Cap Law permits the governing body of any municipality or county to approve
the use of a higher percentage rate up to the index rate. Further, where the
index percentage rate is less than 5 percent, the Cap Law also permits the
governing body of any municipality or county to approve the use of a higher
percentage rate up to 5 percent. Regardless of the rate utilized, certain
exceptions exist to the Cap Law's limitation on increases in appropriations. The
principal exceptions to these limitations are municipal and county
appropriations to pay debt service requirements; to comply with certain other
State or federal mandates; appropriations of private and public dedicated funds;
amounts approved by referendum; and, in the case of municipalities only, to fund
the preceding year's cash deficit with the approval of the Local Finance Board
or to reserve for shortfalls in tax collections, and amounts required pursuant
to contractual obligations for specified services. The Cap Law was re-enacted in
1990 with amendments and made a permanent part of the municipal finance system.
 
  State law also regulates the issuance of debt by local units. The Local Budget
Law limits the amount of tax anticipation notes that may be issued by local
units and requires the repayment of such notes within 120 days of the end of the
fiscal year (six months in the case of the counties) in which issued. The Local
Bond Law governs the issuance of bonds and notes by the local units. No local
unit is permitted to issue bonds for the payment of current expenses (other than
Fiscal Year Adjustment Bonds described more fully below). Local units may not
issue bonds to pay outstanding bonds, except for refunding purposes, and then
only with the approval of the Local Finance Board. Local units may issue bond
anticipation notes for temporary periods not exceeding in the aggregate
approximately ten years from the date of first issue. The debt that any local
unit may authorize is limited to a percentage of its equalized valuation basis,
which is the average of the equalized value of all taxable real property and
improvements within the geographic boundaries of the local unit, as annually
determined by the Director of the Division of Taxation, for each of the three
most recent years. In the calculation of debt capacity, the Local Bond Law and
certain other statutes permit the deduction of certain classes of debt
("statutory deductions") from all authorized debt of the local unit ("gross
capital debt") in computing whether a local unit has exceeded its statutory debt
limit. Statutory deductions from gross capital debt consist of bonds or notes
(i) authorized for school purposes by a regional school district or by a
municipality or a school district with boundaries coextensive with such
municipality to the extent permitted under certain percentage limitations set
forth in the School Bond Law (as hereinafter defined); (ii) authorized for
purposes which are self liquidating, but only to the extent permitted by the
Local Bond Law; (iii) authorized by a public body other than a local unit the
principal of and interest on which is guaranteed by the local unit, but only to
the extent permitted by law; (iv) that are bond anticipation notes; (v) for
which provision for payment has been made or (vi) authorized for any other
purpose for which a
 
                                      B-47
<PAGE>   794
 
deduction is permitted by law. Authorized net capital debt (gross capital debt
minus statutory deductions) is limited to 3.5 percent of the equalized valuation
basis in the case of municipalities and 2 percent of the equalized valuation
basis in the case of counties. The debt limit of a county or municipality, with
certain exceptions, may be exceeded only with the approval of the Local Finance
Board.
 
   
  State law required certain municipalities and permits all other municipalities
to adopt the State fiscal year in place of the existing calendar fiscal year.
The Act provides that municipalities opting to change to a State Fiscal Year
must adopt a six-month transition year budget funded by Fiscal Year Adjustment
Bonds. Notes issued in anticipation of Fiscal Year Adjustment Bonds, including
renewals, can only be issued for up to one year unless the Local Finance Board
permits the municipality to renew them for a further period of time. The Local
Finance Board must confirm the actual deficit experienced by the municipality.
The municipality then may issue Fiscal Year Adjustment Bonds to finance the
deficit on a permanent basis.
    
 
   
  State law authorizes State officials to supervise fiscal administration in any
municipality which is in default on its obligations; which experiences severe
tax collection problems for two successive years; which has a deficit greater
than 4 percent of its tax levy for two successive years; which has failed to
make payments due and owing to the State, county, school district or special
district for two consecutive years; which has an appropriation in its annual
budget for the liquidation of debt which exceeds 25 percent of its total
operating appropriations (except dedicated revenue appropriations) for the
previous budget year; or which has been subject to a judicial determination of
gross failure to comply with the Local Bond Law, the Local Budget Law or the
Local Fiscal Affairs Law which substantially jeopardizes its fiscal integrity.
State officials are authorized to continue such supervision for as long as any
of the conditions exist and until the municipality operates for a fiscal year
without incurring a cash deficit. In September, 1996 the Township of Irvington
requested supervision which was approved by the Local Finance Board and is
expected to continue for at least one year.
    
 
   
  There are 567 municipalities and 21 counties in New Jersey. During 1993, 1994
and 1995 no county exceeded its statutory debt limitations or incurred a cash
deficit in excess of 4 percent of its tax levy. Only two municipalities had a
cash deficit greater than 4% of their tax levies for 1994 and 1995. The number
of municipalities which exceeded statutory debt limits was six as of December
31, 1995. No New Jersey municipality or county has defaulted on the payment of
interest or principal on any outstanding debt obligation since the 1930's.
    
 
SCHOOL DISTRICTS
 
  New Jersey's school districts operate under the same comprehensive review and
regulation as do its counties and municipalities. Certain exceptions and
differences are provided, but the State supervision of school finance closely
parallels that of local governments.
 
  Types of School Districts
 
  All New Jersey school districts are coterminous with the boundaries of one or
more municipalities. They are characterized by the manner in which the board of
education, the governing body of the school district, takes office. Type I
school districts, most commonly found in cities, have a board of education
appointed by the mayor or the chief executive officer of the municipality
constituting the school district. In a Type II school district, the board of
education is elected by the voters of the district. Nearly all regional and
consolidated school districts are Type II school districts.
 
  The State Department of Education has been empowered with the necessary and
effective authority to abolish an existing school board and create a
State-operated school district where the existing school board has failed or is
unable to take the corrective actions necessary to provide a thorough and
efficient system of education in that school district pursuant to N.J.S.A.
18A:7A-15 et seq. (the "School Intervention Act"). The State-operated school
district, operated under the direction of a State-appointed superintendent, has
all of the powers and authority of the local Board of Education and of the local
district superintendent. Pursuant to the authority granted under the School Act,
on October 4, 1989, the State Board of Education ordered the creation of a State
operated school district in the City of Jersey City. Similarly, on August 7,
1991, the State Board of Education ordered the creation of a State operated
school district in the City of Paterson and on July 5, 1995 ordered the creation
of a State-operated school district in the City of Newark.

<PAGE>   795
 
  School Budgets
 
  In every school district having a board of school estimate, the board of
school estimate examines the budget request and fixes the appropriation amounts
for the next year's operating budget after a public hearing at which the
taxpayers and other interested persons shall have an opportunity to raise
objections and to be heard with respect to the budget. This board, whose
composition is fixed by statute, certifies the budget to the municipal governing
bodies and to the local board of education. If the local board of education
disagrees, it must appeal to the State Commissioner of Education (the
"Commissioner") to request changes.
 
   
  In a Type II school district without a board of school estimate, the elected
board of education develops the budget proposal and, after public hearing,
submits it to the voters of such district for approval. Previously authorized
debt service is not subject to referendum in the annual budget process. If
approved, the budget goes into effect. If defeated, the governing body of each
municipality in the school district must determine the amount necessary to be
appropriated for each item appearing in such budget. Should the governing body
fail to certify an amount determined by the Board of Education to be necessary,
the Board of Education may appeal the action to the Commissioner of Education.
    
 
  The State laws governing the distribution of State aid to local school
districts limit the annual increase of a school district's net budget. The
Commissioner certifies the allowable amount of increase for each school district
but may grant a higher level of increase in certain limited instances. A school
district may also submit a proposal to the voters to raise amounts above the
allowable amount of increase. If defeated, such a proposal is subject to further
review or appeal to the Commissioner only if the County Superintendents of
Schools has determined that additional funds are required to provide a thorough
and efficient education.
 
  The County Superintendents of Schools must also review every proposed local
school district budget for the next school year. The County Superintendents of
Schools examine every item of appropriation for current expenses and budgeted
capital outlay to determine their adequacy in relation to the identified needs
and goals of the school district. If in their view they are insufficient, the
County Superintendents of Schools may order remedial action. If necessary, the
Commissioner is authorized to order changes in the school district's budget.
 
  School District Bonds
 
  School district bonds and temporary notes are issued in conformity with
N.J.S.A. 18A:24-1 et seq. (the "School Bond Law"), which closely parallels the
Local Bond Law (for further information relating to the Local Bond Law, see
"MUNICIPAL FINANCE -- Counties and Municipalities" herein). Although school
districts are exempted from the 5 percent down payment provision generally
applied to bonds issued by municipalities and counties, they are subject to debt
limits (which vary depending on the type of school system provided) and to State
regulation of their borrowing. The debt limitation on school district bonds
depends upon the classification of the school district, but may be as high as 4
percent of the average equalized valuation basis of the constituent
municipality. In certain cases involving school districts in cities with
populations exceeding 100,000, the debt limit is 8 percent of the average
equalized valuation basis of the constituent municipality, and in cities with
populations in excess of 80,000 the debt limit is 6 percent of the aforesaid
average equalized valuation.
 
  School bonds are authorized by (i) an ordinance adopted by the governing body
of a municipality within a Type I school district; (ii) adoption of a proposal
by resolution by the board of education of a Type II school district having a
board of school estimate; (iii) adoption of a proposal by resolution by the
board of education and approval of the proposal by the legal voters of any other
Type II school district; or (iv) adoption of a proposal by resolution by a
capital project control board pursuant to N.J.S.A. 18A:7A-46.1 et seq. for
projects in a State operated school district. If school bonds will exceed the
school district borrowing capacity, a school district (other than a regional
school district) may use the balance of the municipal borrowing capacity. If the
total amount of debt exceeds the school district's borrowing capacity and any
available remaining municipal borrowing capacity, the Commissioner and the Local
Finance Board must approve the proposed authorization before it is submitted to
the voters. All authorizations of debt in a Type II school district without a
board of school estimate require an approving referendum, except where, after
hearing, the Commissioner and the State Board of Education determine that the
issuance of such debt is necessary to meet the constitutional
 
                                      B-49
<PAGE>   796
 
obligation to provide a thorough and efficient system of public schools. When
such obligations are issued, they are issued by, and in the name of, the school
district.
 
  School District Lease Purchase Financings
 
  In 1982, school districts were given an alternative to the traditional method
of bond financing capital improvements pursuant to N.J.S.A. 18A:20-4.2(f) (the
"Lease Purchase Law"). The Lease Purchase Law permits school districts to
acquire a site and school building through a lease purchase agreement with a
private lessor corporation. The lease purchase agreement does not require voter
approval. The rent payments attributable to the lease purchase agreement are
subject to annual appropriation by the school district and are required,
pursuant to N.J.A.C. 6:22A-1.2(h), to be included in the annual current expense
budget of the school district. Furthermore, the rent payments attributable to
the lease purchase agreement do not constitute debt of the school district and
therefore do not impact on the school district's debt limitation. Lease purchase
agreements in excess of five years require the approval of the Commissioner and
the Local Finance Board.
 
  New Jersey School Bond Reserve Act
 
   
  The New Jersey School Bond Reserve Act establishes a school bond reserve
within the constitutionally dedicated Fund for the Support of Free Public
Schools. Under this law the reserve is maintained at an amount equal to 1.5
percent of the aggregate outstanding bonded indebtedness of counties,
municipalities or school districts for school purposes (exclusive of bonds whose
debt service is provided by State appropriations), but not in excess of monies
available in such Fund. If a municipality, county or school district is unable
to meet payment of the principal of or interest on any of its school bonds, the
trustee of the school bond reserve will purchase such bonds at the face amount
thereof or pay the holders thereof the interest due or to become due. At June
30, 1996, the book value of the Fund's assets aggregated $88,816,968 and the
reserve, computed as of June 30, 1996, amounted to $40,363,607. There has never
been an occasion to call upon this Fund. The State provides support of certain
bonds of counties, municipalities and school districts through various statutes.
(See "OTHER STATE RELATED OBLIGATIONS -- State Supported School and County
College Bonds" herein).
    
 
QUALIFIED BONDS
 
   
  In 1976, legislation was enacted which provides for the issuance by
municipalities and school districts of "qualified bonds." Whenever a local board
of education or the governing body of a municipality determines to issue bonds,
it may file an application with the Local Finance Board, and, in the case of a
local board of education, the Commissioner, to qualify bonds pursuant to P.L.
1976, c. 38 or c. 39. Upon approval of such an application and after receipt of
a certificate stating the name and address of the paying agent for such bonds,
the maturity schedule, interest rates and payment dates, the State Treasurer
shall, in the case of qualified bonds for school districts, withhold from the
school aid payable to such municipality or school district and, in the case of
qualified bonds for municipalities, withhold from the amount of business
personal property tax replacement revenues, gross receipts tax revenues,
municipal purposes tax assistance fund distributions, State urban aid, State
revenue sharing, and any other funds appropriated as State aid and not otherwise
dedicated to specific municipal programs, payable to such municipalities, an
amount sufficient to cover debt service on such bonds. These "qualified bonds"
are not direct, guaranteed or moral obligations of the State, and debt service
on such bonds will be provided by the State only if the above mentioned
appropriations are made by the State. Total outstanding indebtedness for
"qualified bonds" consisted of $208,642,750 by various school districts as of
June 30, 1996 and $899,586,220 by various municipalities as of June 30, 1996.
    
 
LOCAL FINANCING AUTHORITIES
 
   
  The Local Authorities Fiscal Control Law provides for State oversight of the
fiscal operations and debt issuance practices of independent local authorities
and special taxing districts by the State Department of Community Affairs. The
Local Authorities Fiscal Control Law applies to all autonomous public bodies
created by counties or municipalities, which are empowered to issue bonds, to
impose facility or service charges, or to levy taxes in their districts. This
encompasses most autonomous local authorities (sewerage, municipal utilities,
parking, pollution control, improvement, etc.) and special taxing districts
(fire, water,
    
 
                                      B-50
<PAGE>   797
 
etc.). Authorities which are subject to differing State or federal financial
restrictions are exempted, but only to the extent of that difference.
 
  Financial control responsibilities over local authorities and special
districts are assigned to the Local Finance Board and the Director of the
Division of Local Government Services. The Local Finance Board exercises
approval power over the creation of new authorities and special districts as
well as their dissolution. The Local Finance Board also reviews, conducts public
hearings and issues findings and recommendations on any proposed project
financing of an authority or district, and on any proposed financing agreement
between a municipality or county and an authority or special district. The Local
Finance Board prescribes minimum audit requirements to be followed by
authorities and special districts in the conduct of their annual audits. The
Director reviews and approves annual budgets of authorities and special
districts.
 
   
  As of June 30, 1995 there were 195 locally created authorities with a total
outstanding capital debt of $7,149,326,992 (figures do not include housing
authorities and redevelopment agencies). This amount reflects outstanding bonds,
notes, and loans payable by the authorities as of their respective fiscal years
ended nearest to June 30, 1995.
    
 
                                STATE EMPLOYEES
 
PUBLIC EMPLOYER-EMPLOYEE RELATIONS ACT
 
  The State of New Jersey, as a public employer, is covered by the New Jersey
Public Employer-Employee Relations Act, as amended which guarantees public
employees the right to negotiate collectively through employee organizations
certified or recognized as the exclusive collective negotiations representatives
for units of public employees found to be appropriate for collective
negotiations purposes. Approximately 64,500 employees are paid through the State
payroll system. Of the 64,500 employees, 56,800 are represented by certified or
recognized exclusive majority representatives and are organized into various
negotiation units.
 
                               FINANCING PENSIONS
 
   
  Virtually all of the public employees of the State and its counties,
municipalities and political subdivisions are members of pension plans
administered by the State. The State operates seven retirement plans. Public
Employees' Retirement System ("PERS") and Teachers Pension and Annuity Fund
("TPAF"), originally created by acts of the State Legislature in 1920 and 1919,
respectively, are the principal plans, together covering 387,554 of the total
428,988 active members covered by all State-administered plans. The other
systems are Police and Firemen's Retirement System ("PFRS") (38,450 members),
Consolidated Police and Firemen's Pension Fund ("CP&FPF") (no active members),
State Police Retirement System ("SPRS") (2,574 active members), Judicial
Retirement System ("JRS") (410 active members) and Prison Officers' Pension Fund
("POPF") (no active members).
    
 
   
  The various pension funds were analyzed between July 1, 1995 and March 31,
1996 by independent actuaries who reported that the present value of accumulated
benefits, the Accumulated Benefit Obligation determined in accordance with
Statement No. 87 of the Financial Accounting Standards Board (including the
present value of post-retirement medical benefits for PERS state employees and
TPAF), for which the State is obligated (including both vested and non-vested
benefits) for the seven pension funds approximates $43 billion at the valuation
dates. The studies indicated that the market value of all assets of the funds
was $47.3 billion which, when compared to the $43 billion Accumulated Benefit
Obligation, represents a funding level of 110.1%. The present value of projected
benefits, the Pension Benefit Obligation determined in accordance with Statement
No. 5 of the Governmental Accounting Standards Board, of the funds is $49.7
billion. The funding level for the projected benefits is 87.4%.
    
 
   
  $603.9 million is provided in the Fiscal Year 1997 adjusted Appropriations Act
as the State's contributions to public retirement plans.
    
 
  Chapter 62, Laws of 1994, enacted by the State Legislature and approved by the
Governor on June 30, 1994 made several changes to the funding of the pension
systems, including the Public Employees Retirement
 
                                      B-51
<PAGE>   798
 
System, the Teachers' Pension and Annuity Fund, the Judicial Retirement System,
the State Police Retirement System, and the Police and Firemen's Retirement
System. These reforms include: a change of the actuarial method used to
determine funding requirements for the systems from the entry age normal to the
projected unit credit method; revision of funding for post-retirement medical
benefits under TPAF and PERS; phase in of revised actuarial assumptions under
TPAF; elimination of 2% subsidy in employee pension contributions rates under
TPAF and PERS and implementation of a flat employee contribution rate of 5%;
return to the original phase-in schedule for recognition of the liability for
pension adjustment benefits, Cost of Living Adjustment ("COLA") for active
members; reduction in the salary increase assumption to an average of 5.95% and
a reduction in the inflation assumption for COLA benefits to 2.4%.
 
  Certain unions and various individuals have instituted litigation in the
United States District Court in Newark challenging the changes to the pension
systems which were made by the State Legislature when it enacted P.L. 1994, c.
62. (See "LITIGATION -- New Jersey Education Association et al. v. State of New
Jersey et al.").
 
                                   LITIGATION
 
  The following are cases presently pending or threatened in which the State has
the potential for either a significant loss of revenue or a significant
unanticipated expenditure.
 
   
  New Jersey Education Association et. al v. State of New Jersey et. al. This
case represents a challenge to amendments to the pension laws enacted on June
30, 1994 (P.L. 1994, Chapter 62), which concerned the funding of the Teachers
Pension and Annuity Fund ("TPAF"), the Public Employee's Retirement System
("PERS"), the Police and Fireman's Retirement System ("PFRS"), the State Police
Retirement System ("SPRS") and the Judicial Retirement System ("JRS"). The
complaint was filed in the United States District Court of New Jersey on October
17, 1994. The statute, P.L. 1994, Chapter 62 ("Chapter 62"), as enacted, made
several changes affecting these retirement systems including changing the
actuarial funding method to projected unit credit; continuing the prefunding of
post-retirement medical benefits but at a reduced level for TPAF and PERS;
revising the employee member contribution rate to a flat 5% for TPAF and PERS;
extending the phase in period for the revised TPAF actuarial assumptions;
changing the phase-in period for funding of cost-of-living adjustments and
reducing the inflation assumption for the Cost of Living Adjustment ("COLA") for
all retirement systems; and decreasing the average salary increase assumption
for all retirement systems. Plaintiffs allege that the changes resulted in lower
employer contributions in order to reduce a general budget deficit. The
complaint further alleges that certain provisions of Chapter 62 violate the
contract, due process, and taking clauses of the United States and New Jersey
Constitutions, and further constitute a breach of the State's fiduciary duty to
participants in TPAF and PERS. Plaintiffs seek to permanently enjoin the State
from administering, enforcing or otherwise implementing Chapter 62. An adverse
determination against the State would have a significant impact upon the Fiscal
Year 1997 budget and the proposed Fiscal Year 1998 budgets. The State filed a
motion to dismiss and a motion for summary judgment.
    
 
  On October 6, 1995, the Court issued its opinion in which it dismissed the
State as a party to the action. The only defendant is Treasurer Clymer. The
claims surviving the motion are: (1) breach of trust and fiduciary duty (against
the Treasurer in both his individual and official capacities); (2) violation of
Due Process (against the Treasurer in both his individual and official
capacities); and (3) a 42 U.S.C. sec. 1983 claim (against the Treasurer in his
individual capacity).
 
  The forms of relief sought related to these surviving claims are: (1) a
declaration that certain provisions of Chapter 62 violate Due Process of law
under the Fifth and Fourteenth Amendments to the U.S. Constitution; (2) a
declaration that the enactment and implementation of certain provisions of
Chapter 62 constitute a breach of the fiduciary obligations owed to contributing
participants, vested participants and retirees of the TPAF and PERS; (3) a
declaration that Chapter 62 contravenes the statutory and common law duties to
administer and fund the plans in an actuarially sound and fiscally responsible
manner; (4) a permanent injunction against administering, enforcing or otherwise
implementing certain provisions of Chapter 62; (5) directing payment of
plaintiffs' attorneys' fees, disbursements and costs pursuant to 42 U.S.C. sec.
1988.

  The State filed a motion for reconsideration or, in the alternative, for
certification to the Third Circuit Court of Appeals, of the remaining claims. By
order dated December 19, 1995, the District Court denied the motion in all
respects. On January 29, 1996, the State, on behalf of Treasurer Clymer, filed a
Petition for a Writ of Mandamus and a Motion for a Stay of the Proceedings
below, pending consideration and disposition of the petition, with the Third
Circuit Court of Appeals. In the petition, Treasurer Clymer asked the Court of
Appeals to direct the District Court to dismiss the complaint or enter summary
judgment in his favor. Alternatively, the Treasurer asked the Court of Appeals
to order the District Court to vacate its order denying summary judgment and
resolve that motion as a matter of law without discovery or fact finding or to
certify the issues for interlocutory appeal. The Third Circuit Court of Appeals
denied the motion and petition on February 20, 1996. The matter is currently
stayed pending the adoption of the Appropriations Act for Fiscal Year 1998. The
State intends to vigorously defend this action.
    
 
   
  Beth Israel Hospital et. al. v. Essential Health Services Commission. This
case represents a challenge by eleven New Jersey hospitals to the .53% hospital
assessment authorized by the Health Care Reform Act of 1992, specifically
N.J.S.A. 26:2H-18.62. Amounts collected pursuant to the assessment are paid into
the hospital and other health care initiatives account of the Health Care
Subsidy Fund, to be used for various health care programs. Specifically, the
funds are currently used for those programs previously established pursuant to
N.J.S.A. 26:2H-18.47. In this appeal of the assessment, filed with the Appellate
Division on December 6, 1993, appellants argue that collection of the assessment
is invalid in the absence of Hospital Rate Setting Commission approval of the
approved revenue base used in the calculation. At the same time, appellants
filed an application for injunctive relief, seeking to stay any collection,
which application was denied. In a decision dated July 10, 1995, the Appellate
Division rejected appellants' contention that the respondents were prohibited
from collecting the assessment. However, the court also found that the hospitals
had not been afforded an opportunity to be heard on the assessment, and thus
remanded the case to the Essential Health Services Commission for a hearing.
Because the Commission has been abolished by L. 1995, c. 133, and its
responsibilities assigned to the Department of Health, the Department of Health
held the hearing on August 30, 1995. By letters dated March 26, 1996, the
Department of Health affirmed the prior assessments. The hospitals filed a
notice of appeal challenging that decision on May 10, 1996 and the case has now
been briefed. The State intends to vigorously defend this action.
    
 
   
  Tort, Contract and Other Claims. At any given time, there are various numbers
of claims and cases pending against the State, State agencies and employees,
seeking recovery of monetary damages that are primarily paid out of the fund
created pursuant to the New Jersey Tort Claims Act. The State does not formally
estimate its reserve representing potential exposure for these claims and cases.
The State is unable to estimate its exposure for these claims and cases.
    
 
  The State routinely receives notices of claim seeking substantial sums of
money. The majority of those claims have historically proven to be of
substantially less value than the amount originally claimed. Under the New
Jersey Tort Claims Act, any tort litigation against the State must be preceded
by a notice of claim, which affords the State the opportunity for a six-month
investigation prior to the filing of any suit against it.
 
  In addition, at any given time, there are various numbers of contract and
other claims against the State and State agencies, including environmental
claims asserted against the State, among other parties, arising from the alleged
disposal of hazardous waste. Claimants in such matters are seeking recovery of
monetary damages or other relief which, if granted, would require the
expenditure of funds. The State is unable to estimate its exposure for these
claims.
 
   
  At any given time, there are various numbers of claims and cases pending
against the University of Medicine and Dentistry and its employees, seeking
recovery of monetary damages that are primarily paid out of the Self Insurance
Reserve Fund created pursuant to the New Jersey Tort Claims Act. An independent
study estimated an aggregate potential exposure of $86,795,000 for tort and
medical malpractice claims pending as of June 30, 1996. In addition, at any
given time, there are various numbers of contract and other claims against the
University of Medicine and Dentistry, seeking recovery of monetary damages or
other relief which, if granted, would require the expenditure of funds. The
State is unable to estimate its exposure for these claims.

  County of Passaic v. State of New Jersey. This action filed by the County of
Passaic, the Passaic County Utilities Authority, and the Passaic County
Pollution Control Financing Authority ("plaintiffs"), alleged tort and
contractual claims against the State of New Jersey ("State") and the New Jersey
Department of Environmental Protection ("NJDEP") associated with a resource
recovery facility which plaintiffs had once planned to build. The plaintiffs
alleged that the State and the NJDEP violated a 1984 consent order concerning
the construction of a resource recovery facility in Passaic County. Plaintiffs'
complaint alleged approximately $30 million in damages against the State and the
NJDEP. On March 17, 1995, the court granted the State's motion for summary
judgment, dismissing all counts of plaintiffs' complaint against the State and
the NJDEP, with prejudice. The court found that there was no legal obligation or
duty on the part of the State or the NJDEP concerning the project. Plaintiffs
have filed an appeal of the court's decision. The State intends to vigorously
defend this appeal.
 
   
  Camden Co. v. Waldman, et al. Fifteen counties seek a portion of the $412
million in federal funds that the State received for disproportionate share
hospital payments it made to psychiatric hospitals during July 1, 1988 through
July 1, 1991. Camden County filed the first action against the Department of
Human Services, the Attorney General and the State Treasurer. Camden County
contends that the Essex decisions mandate sharing of the federal funding. The
first Essex case dealt with sharing maintenance costs when there have been
social security payments that the State received as representative payee. The
second Essex case dealt with sharing Medicaid payment recoveries. The State
contended that under a recently approved Medicaid state plan amendment and
federal law, the State does not have to share the federal funding because it
already paid the counties their portion of disproportionate share hospital
payments. The State also contended that the Legislature did not intend to share
the federal funding with the counties as evidenced by appropriations act
language. The actions against the attorney General and State Treasurer were
dismissed and the matter was transferred to the Appellate Division.
    
 
   
  Similar lawsuits were filed by Middlesex, Monmouth, Atlantic, Union, Hudson,
Ocean, Mercer, Somerset, Morris, Sussex, Cape May, Essex, Warren and Passaic
counties. The Middlesex, Monmouth, Atlantic, Union, Ocean, Mercer, Morris,
Warren and Hudson County cases were transferred to the Appellate Division. The
Atlantic, Camden and Monmouth counties cases were consolidated. Cape May joined
in the existing calendar matters. The other counties, Essex, Warren and Passaic,
have recently had their cases transferred to the Appellate Division, but did not
seek to join in the existing matters. With the exception of Essex, Warren and
Passaic, the remaining matters were to be heard on a back to back basis by the
Appellate Division. A motion to consolidate or calendar these matters back to
back was made by the State. The State and counties filed their briefs. The State
requested oral argument because of the complicated nature of the issues and the
large amount of money involved; the Court granted the request.
    
 
   
  The Court heard oral argument on May 30, 1996. On July 15, 1996, three-judge
panel of the Appellate Division ruled unanimously in favor of the State. Finding
no federal requirement compelling the State to share these monies, the Court
agreed with the State's position that the Legislature may determine to
appropriate these funds to the General Fund and therefore the county had no
State law claim to share in them. Of the fourteen appellant counties, eight
filed motions for reconsideration, which were denied by order of the Appellate
Division on September 16, 1996, nine have filed Notices of Petition for
Certification to the New Jersey Supreme Court, three have filed Motions for
Extension in which to file Notices of Petition, ten have filed Motions for
Extension in which to file Petitions and eight have filed Notices of Appeal.
Pursuant to an Order of the Court, petitions were due by November 15, 1996.
    
 
  Interfaith Community Organization v. Shinn, et al. In late October, 1993, the
Interfaith Community Organization ("ICO") a coalition of churches and church
leaders in Hudson County, filed suit on behalf of the ICO's membership and the
citizens of Hudson County against the Governor, the Commissioner of the New
Jersey Department of Environmental Protection ("DEP"), Commissioner of the
Department of Health ("DOH"), and Lance Miller, Assistant Commissioner of DEP.
The multicount complaint alleged violations of numerous laws, allegedly
resulting from the existence of chromium contamination in the State-owned
Liberty State Park in Jersey City. It also asserted the alleged failure by DEP
and DOH to properly conduct remediation and health screens in Hudson County
concerning chromium contamination. No immediate relief was sought, but
injunctive and monetary relief was asked for.

  In June 1994, ICO hired a law firm to represent it in this matter. The firm
filed amended complaints, naming only Commissioner Shinn of DEP and Governor
Whitman as defendants and alleges only Clean Water Act ("CWA") and Resource
Conservation Recovery Act ("RCRA") violations at Liberty State Park. Under the
"citizen suit" provisions of these federal acts, plaintiff is seeking
remediation, health studies and attorneys' fees. The State is unable to estimate
its exposure for this claim. In March, 1995, ICO filed another lawsuit over the
shipments of soil from the I-287 Wetlands Mitigation Project to Liberty State
Park. The defendants in that suit are Commissioner Shinn, Governor Whitman,
Commissioner Wilson of the Department of Transportation ("DOT") and R. W. Vogel,
Inc., the transporter of the soil. The new suit seeks a declaration that the CWA
is being violated and demands cessation of all construction at Liberty State
Park and penalties against Vogel. The state intends to defend these suits
vigorously.
    
 
   
  Waste Management of Pennsylvania et al v. Shinn et al. This action filed in
federal district court by Waste Management of Pennsylvania, Inc. and its
affiliate Geological Reclamation Operations and Waste Systems, Inc.
("plaintiffs") seeks declaratory and injunctive relief and compensatory damages
in excess of $19 million from Department of Environmental Protection
Commissioner Robert C. Shinn, Jr. and former Acting Commissioner Jeanne M. Fox,
("defendants") individually and in their official capacity. These claims are
based on alleged violations of the Commerce Clause and the Contracts Clause of
the United States Constitution as a result of the issuance by defendants of two
emergency redirection orders and a draft permit. The State's position is that
none of the contracts to which the plaintiffs are a party entitle them to any
relief and that therefore none of their constitutional rights have been impaired
by the Commissioners' actions. Moreover, all of the administrative agency
actions which form the gravamen of the federal complaint are currently the
subject of review in either New Jersey appellate courts or within the
Department. The compensatory damage claims against defendants Robert C. Shinn,
Jr. and Jeanne M. Fox were dismissed by way of stipulation of the parties filed
on December 15, 1995. Remaining claims in the action are injunctive and require
declaratory relief.
    
 
  American Trucking Associations, Inc. and Tri-State Motor Transit, Co. v. State
of New Jersey. The American Trucking Associations, Inc. ("ATA") and Tri-State
Motor Transit, Co. filed a complaint in the Tax Court on March 23, 1994 against
the State of New Jersey and certain state officials challenging the
constitutionality of annual A-901 hazardous and solid waste licensure renewal
fees collected by the Department of Environmental Protection ("DEP"). A-901
refers to the Assembly bill number which was adopted in 1983 as an amendment to
the Solid Waste Management Act N.J.S.A. 13:1E-1 et seq. and codified at N.J.S.A.
13:1E-126 et seq., establishing a requirement that all persons and entities
engaged in solid and hazardous waste activities in the State be investigated
prior to the issuance of a license. Plaintiffs are alleging that the A-901
renewal fees discriminate against interstate commerce in violation of the
Commerce Clause of the United States Constitution; that the fees are not used
for the purposes for which they are levied; and that the fees do not reflect the
duration or complexity of the services rendered by the government entities
receiving the fees as required under the A-901 statute. Plaintiffs are seeking a
declaration that the fees are unconstitutional; a permanent injunction enjoining
the future collection of the fees; a refund of all annual A-901 renewal fees and
all fines and penalties collected pursuant to enforcement of these provisions;
and attorneys' fees and costs. Plaintiffs are also seeking class certification
of their action.
 
  The DEP currently collects approximately $3.5 to $4 million in A-901 fees
annually. In previous years, the total amount of fees collected was higher
because the number of applicants and licensees subject to the fees was much
larger. It is presently unknown what portion of the A-901 fees are paid by
haulers engaged in interstate commerce, and what percentage of the monies are
renewal fees as opposed to initial application fees. Consequently, the State is
unable to estimate its exposure for this claim and intends to defend this suit
vigorously.
 
   
  Abbot v. Burke. On January 6, 1997, the Education Law Center filed a motion in
aid of litigants' rights with the Supreme Court of New Jersey in the Abbot v.
Burke matter. In 1994, the Supreme Court ruled in Abbot v. Burke that the State
had to enact a funding formula that would close the spending gap between poor
urban school districts and wealthy suburban districts by Fiscal Year 1998. On
December 20, 1996, the Comprehensive Education Improvement and Financing Act
("CEIFA") was enacted. CEIFA is a departure from the mechanisms of previous
funding formulas. The CEIFA is centered upon the Core Curriculum Content
Standards -- a comprehensive description of what all students should know and be
able to

accomplish upon completion of a thirteen year public education. The State
projects that special needs districts will be spending between 91% and 96% of
the wealthy suburban districts in the 1997-1998 school year under CEIFA.
Plaintiffs concede that, under CEIFA, special needs districts are projected to
be spending at 91% of the wealthy suburban districts in the 1997-1998 fiscal
year. In its motion, the Education Law Center requests, in part, relief in the
form of 100% spending parity or State aid in the amount of approximately $200
million dollars to be redistributed to the special needs districts. On March 4,
1997 the Supreme Court heard oral argument on the motion. The Supreme Court has
not yet rendered a decision.
    
 
   
  Affiliated FM Insurance Company, et al. v. State of New Jersey, et al. The
plaintiffs in this action are insurers licensed or admitted to write property
and casualty insurance in the State of New Jersey pursuant to N.J.S.A. 17:17-1
et seq. and are all members of the New Jersey Property-Liability Insurance
Guaranty Association ("PLIGA"), a private, non-profit organization created to
cover claims against certain insolvent insurers. Plaintiffs have filed suit in
the Superior Court of New Jersey, Chancery Division, Mercer County against the
State of New Jersey, the Commissioner of Banking, the Department of Banking and
Insurance, PLIGA and the State Treasurer. Plaintiff's contend that their
assessments are being used to retire debt of the Market Transition Fund ("MTF").
The plaintiffs argue that they were never members of the MTF, are not
statutorily responsible for its losses, have not agreed to assume its losses and
did not relinquish any right to repayment of loan assessments to PLIGA. Under
the Fair Automobile Insurance Reform Act of 1990 ("FAIRA"), PLIGA is responsible
for assessing and collecting from its member insurers the amounts necessary to
make certain loans to the Auto Guaranty Fund (the "Auto Guaranty Fund"), a
special nonlapsing fund created pursuant to FAIRA. Plaintiffs contend that
assessments dating back to 1990 are in dispute and challenge the
constitutionality of the assessments and legislation which allow the assessments
and request declaratory relief and an order that the monies assessed since 1990
be returned as well as an accounting. The State intends to vigorously defend
this action and has filed a motion to dismiss this case.
    
 
   
  C.F., et al. v. Fauver, et al. This case is brought as a purported class
action consisting of prisoners with serious mental disorders who are confined
within the facilities of the Department of Corrections (the "Class") against the
Commissioner of the Department of Corrections and other officers of the
Department of Corrections. The Class alleges cruel and unusual punishment,
violation of the Americans with Disabilities Act of 1990, discrimination against
members of the Class, sex discrimination and violation of due process. The suit
was brought by the Class in the United States District Court of the District of
New Jersey. Through this action, the Class seeks injunctive relief in the form
of changes to the manner in which mental health services are provided to
inmates. The Class also seeks changes in the disciplinary process to the extent
that an inmate's mental health is taken into consideration by a hearing officer
when adjudicating a disciplinary charge. Discovery has commenced and is
continuing. The State intends to vigorously defend this action.
    
 
   
  Cleary v. Waldman. This case involves the spousal impoverishment provisions of
the Medicare Catastrophic Coverage Act ("MCCA"). Under this provision, the
spouse of an institutionalized husband or wife, is allowed to have sufficient
funds to live in the community, called the monthly needs allowance.
    
 
   
  The State in determining a spouse's monthly needs allowance, uses a system
called the "income first" rule. If a community spouse does not have sufficient
funds to meet the monthly needs allowance, an institutionalized spouse is
allowed to shift his or her income to the community spouse to make up the
difference. If the institutionalized spouse's income is insufficient to meet the
monthly needs allowance, then the institutionalized spouse is allowed to shift
resources to the community spouse to generate income to make the difference.
    
 
   
  A class action was brought in federal court in which plaintiffs' argue that
the income first rule is disallowed under the MCCA. Rather plaintiff's claim
that the MCCA mandates the use of what is called the "resource-first" rule.
Under this scheme, before income is shifted from the institutionalized spouse to
the community spouse to meet the monthly needs allowance, resources must be
shifted first and income generated from these resources used to meet the monthly
needs allowance.
    
 
   
  Estimates of exposure if a court were to find that the MCCA only allows the
"resource-first" rule has been estimated in the area of $50 million per year
from both State and Federal sources combined.
    
 
   
  Plaintiff's filed for a preliminary injunction arguing that, under federal
law, only the resource first rule was allowed under the MCCA. The State opposed
the motion and the New Jersey Association of Health Care
    
 
                                      B-56
<PAGE>   803
 
   
Facilities and the New Jersey Association for Non-Profit Homes for the Aging
moved for intervenor status, opposing the plaintiffs' motion. The court granted
the motion of intervention and denied the motion for preliminary injunction,
finding that plaintiffs were unlikely to prevail on the merits since New
Jersey's methodology was at least a permissible application of the federal law.
    
 
   
  Subsequently, plaintiffs filed for class certification which was granted on
March 25, 1996. On March 26, 1997, Plaintiffs have filed a Notice of Appeal to
the Court of Appeals for the Third Circuit. The State intends to vigorously
defend this action.
    
 
   
  United Hospitals, et al. v. State of New Jersey and William Waldman. This case
represents a challenge by 18 New Jersey hospitals to Medicaid hospital
reimbursement since February, 1995. The matter was filed in the Appellate
Division of the Superior Court of New Jersey in January, 1997. The hospitals
challenge all of the following: (i) whether the State complied with certain
federal requirements for Medicaid reimbursement; (ii) whether the State's
reimbursement regulations, N.J.A.C. 10:52-1 et. seq., are arbitrary, capricious
and unreasonable; (iii) whether the Department of Human Services (DHS)
incorrectly calculated the rates; (iv) whether DHS denied hospitals of a
meaningful appeal process; (v) whether the 1996-1997 State Appropriations Act
violates the New Jersey Constitution with respect to the provision for Medicaid
reimbursement to hospitals; and (vi) whether DIIS violated the Medicaid State
Plan, filed with the U.S. Department of Health and Human Services, in
implementing hospital rates in 1995 and 1996. The State intends to vigorously
defend this action.
    
 
   
  Trump Hotels & Casino Resorts, Inc. v. Mirage Resorts Incorporated, The State
of New Jersey, et al. An action was filed in Federal District Court to enjoin
and declare unlawful actions of the Mirage Resorts Incorporated ("Mirage"), the
State of New Jersey, the New Jersey Department of Transportation, the South
Jersey Transportation Authority, the Casino Reinvestment Development Authority
("CRDA"), the New Jersey Transportation Trust Fund Authority and certain
officials of the aforesaid agencies and authorities in their efforts to
revitalize Atlantic City through the design and construction of a highway and
tunnel funded by Mirage, the New Jersey Transportation Trust Fund Authority and
$55,000,000 in bonds to be issued by the South Jersey Transportation Authority
and collateralized by future alternative investment obligations of casinos to be
located in the marina district of Atlantic City. Plaintiffs claim that the
highway and tunnel development funding violates a provision of the New Jersey
State Constitution that requires the State to dedicate all State revenues
derived from gambling to programs benefiting the elderly and the disabled
pursuant to the New Jersey State Constitution, Article IV, Section 7, Paragraph
2. The plaintiffs further allege that (i) the failure to disclose the
constitutional infirmities alleged in the financing for the highway and tunnel
project will be material omissions within the meaning of Rule 10b-5 of the
Securities and Exchange Act of 1934; (ii) the defendants have sought to avoid
the federal requirements of the Clean Water Act, the Federal Highway Act, and
the Clean Air Act; and (iii) the defendants have sought to avoid the requirement
of the New Jersey Coastal Area Facility Review Act. The State has filed a motion
to dismiss the federal action and filed a declaratory judgment action in
Superior Court of New Jersey, Law Division -- Atlantic County, seeking a
declaration that the alternative investment program established under N.J.S.A.
5:12-144.1 of the CRDA legislation and the use of parking fees and sales tax
revenues under the CRDA legislation to fund eligible projects do not violate the
New Jersey State Constitution.
    
 
   
  Three additional cases have been filed in opposition to the road and tunnel
project which also contain similar challenges. The three matters, Bryant, et al.
v. New Jersey Department of Transportation, et al., Merolla and Brady v. The
Casino Reinvestment Development Authority, et al., and Gallagher, et al. v. The
Casino Reinvestment Development Authority, et al. are also being vigorously
defended by the State.

                               December 31, 1996
- --------------------------------------------------------------------------------
 
1. SIGNIFICANT ACCOUNTING POLICIES
 
Van Kampen American Capital New Jersey Tax Free Income Fund (the "Fund") is
organized as a series of the Van Kampen American Capital Tax Free Trust, a
Delaware business trust, and is registered as a non-diversified open-end
management investment company under the Investment Company Act of 1940, as
amended. The Fund's investment objective is to provide investors with a high
level of current income exempt from federal income tax and New Jersey gross
income tax, consistent with preservation of capital. The Fund commenced
investment operations on July 29, 1994.
 
    The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. The
preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.
 
A. SECURITY VALUATION--Investments are stated at value using market quotations
or, if such valuations are not available, estimates obtained from yield data
relating to instruments or securities with similar characteristics in accordance
with procedures established in good faith by the Board of Trustees. Short-term
securities with remaining maturities of 60 days or less are valued at amortized
cost.
 
B. SECURITY TRANSACTIONS--Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis. The
Fund may purchase and sell securities on a "when issued" or "delayed delivery"
basis, with settlement to occur at a later date. The value of the security so
purchased is subject to market fluctuations during this period. The Fund will
maintain, in a segregated account with its custodian, assets having an aggregate
value at least equal to the amount of the when issued or delayed delivery
purchase commitments until payment is made. As of December 31, 1996, there were
no when issued or delayed delivery purchase commitments.
 
C. INVESTMENT INCOME--Interest income is recorded on an accrual basis. Bond
premium and original issue discount are amortized over the expected life of each
applicable security.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
                               December 31, 1996
- --------------------------------------------------------------------------------
 
D. ORGANIZATIONAL EXPENSES--The Fund will reimburse Van Kampen American Capital
Distributors, Inc. or its affiliates (collectively "VKAC") for costs incurred in
connection with the Fund's organization in the amount of $120,000. These costs
are being amortized on a straight line basis over the 60 month period ending
July 28, 1999. Van Kampen American Capital Investment Advisory Corp. (the
"Adviser") has agreed that in the event any of the initial shares of the Fund
originally purchased by VKAC are redeemed by the Fund during the amortization
period, the Fund will be reimbursed for any unamortized organizational expenses
in the same proportion as the number of shares redeemed bears to the number of
initial shares held at the time of redemption.
 
E. FEDERAL INCOME TAXES--It is the Fund's policy to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income, if any, to its shareholders.
Therefore, no provision for federal income taxes is required.
 
    The Fund intends to utilize provisions of the federal income tax laws which
allow it to carry a realized capital loss forward for eight years following the
year of the loss and offset such losses against any future realized capital
gains. At December 31, 1996, the Fund had an accumulated capital loss
carryforward for tax purposes of $245,890 which will expire on December 31,
2003. Net realized gains or losses may differ for financial reporting and tax
purposes primarily as a result of post October 31 losses which may not be
recognized for tax purposes until the first day of the following year.
 
F. DISTRIBUTION OF INCOME AND GAINS--The Fund declares daily and pays monthly
dividends from net investment income. Net realized gains, if any, are
distributed annually. Due to inherent differences in the recognition of certain
expenses under generally accepted accounting principles and federal income tax
purposes, the amount of distributable net investment income may differ between
book and federal income tax purposes for a particular period. These differences
are temporary in nature, but may result in book basis distribution in excess of
net investment income for certain periods.
 
    For the year ended December 31, 1996, 100% of the income distributions made
by the Fund were exempt from federal income taxes.

</TABLE>
 
    Certain legal expenses are paid to Skadden, Arps, Slate, Meagher & Flom,
counsel to the Fund, of which a trustee of the Fund is an affiliated person.
 
    For the year ended December 31, 1996, the Fund recognized expenses of
approximately $7,300 representing VKAC's cost of providing cash management and
legal services to the Fund. All of this cost has been assumed by VKAC.
 
    ACCESS Investor Services, Inc. ("ACCESS"), an affiliate of the Adviser,
serves as the shareholder servicing agent for the Fund. For the year ended
December 31, 1996, the Fund recognized expenses of approximately $5,800,
representing ACCESS's cost of providing transfer agency and shareholder services
plus a profit. All of this expense has been assumed by VKAC.
 
    Certain officers and trustees of the Fund are also officers and directors of
VKAC. The Fund does not compensate its officers or trustees who are officers of
VKAC.
 
    The Fund has implemented deferred compensation and retirement plans for its
trustees. Under the deferred compensation plan, trustees may elect to defer all
or a portion of their compensation to a later date. The retirement plan covers
those trustees who are not officers of VKAC.
 
    At December 31, 1996, VKAC owned 100 shares each of Classes A, B and C.
 
3. CAPITAL TRANSACTIONS
 
The Fund has outstanding three classes of shares of beneficial interest, Classes
A, B and C, each with a par value of $.01 per share. There are an unlimited
number of shares of each class authorized.

                      STATEMENT OF ADDITIONAL INFORMATION
 
           VAN KAMPEN AMERICAN CAPITAL NEW YORK TAX FREE INCOME FUND
 
  Van Kampen American Capital New York Tax Free Income Fund, formerly known as
Van Kampen Merritt New York Tax Free Income Fund (the "Fund"), seeks to provide
investors with high current income exempt from federal, New York State and New
York City income taxes consistent with preservation of capital. The Fund is
designed for investors who are residents of New York for tax purposes. Under
normal market conditions, the Fund attempts to achieve its investment objective
by investing at least 80% of its assets in a portfolio of New York municipal
securities rated investment grade at the time of investment. Investment grade
securities are securities rated BBB or higher by Standard & Poor's Ratings Group
("S&P"), Baa or higher by Moody's Investors Service, Inc. ("Moody's") or an
equivalent rating by another nationally recognized statistical rating
organization ("NRSRO"). Up to 20% of the Fund's total assets may consist of New
York municipal securities rated below investment grade (but not rated lower than
B- by S&P, B3 by Moody's or an equivalent NRSRO) and unrated New York municipal
securities believed by the Fund's investment adviser to be of comparable
quality, which involve special risk considerations. There is no assurance that
the Fund will achieve its investment objective. The Fund is a separate series of
Van Kampen American Capital Tax Free Trust, a Delaware business trust (the
"Trust").

                             THE FUND AND THE TRUST
 
   
  Van Kampen American Capital New York Tax Free Income Fund (the "Fund") is a
separate series of the Trust, an open-end non-diversified management investment
company. At present, each of the Fund, Van Kampen American Capital Insured Tax
Free Income Fund, Van Kampen American Capital Tax Free High Income Fund, Van
Kampen American Capital Municipal Income Fund, Van Kampen American Capital
Intermediate Term Municipal Income Fund, Van Kampen American Capital California
Insured Tax Free Fund, Van Kampen American Capital Florida Insured Tax Free
Income Fund and Van Kampen American Capital New Jersey Tax Free Income Fund has
been organized as a series of the Trust and have commenced investment
operations. Each of Van Kampen American Capital California Tax Free Income Fund,
Van Kampen American Capital Michigan Tax Free Income Fund, Van Kampen American
Capital Missouri Tax Free Income Fund, and Van Kampen American Capital Ohio Tax
Free Income Fund has been organized as a series of the Trust and have not
commenced investment operations. Other series may be organized and offered in
the future. The Fund was originally organized in 1994 under the name Van Kampen
Merritt New York Tax Free Income Fund, as a sub-trust of Van Kampen Merritt Tax
Free Fund, a Massachusetts business trust. The Fund was reorganized as a series
of the Trust and adopted its present name as of July 31, 1995.
    
 
  The Trust is an unincorporated business trust established under the laws of
the State of Delaware by an Agreement and Declaration of Trust (the "Declaration
of Trust") dated as of May 10, 1995. The Declaration of Trust permits the
Trustees to create one or more separate investment portfolios and issue a series
of shares for each portfolio. The Trustees can further sub-divide each series of
shares into one or more classes of shares for each portfolio. The Trust can
issue an unlimited number of shares, par value $0.01 (prior to July 31, 1995,
the shares had no par value). Each share represents an equal proportionate
interest in the assets of the series with each other share in such series and no
interest in any other series. No series is subject to the liabilities of any
other series. The Declaration of Trust provides that shareholders are not liable
for any liabilities of the Trust or any of its series, requires inclusion of a
clause to that effect in every agreement entered into by the Trust or any of its
series and indemnifies shareholders against any such liability.
 
  Shares of the Trust entitle their holders to one vote per share; however,
separate votes are taken by each series on matters affecting an individual
series. For example, a change in investment policy for a series would be voted
upon by shareholders of only the series involved. Except as described in the
Prospectus, shares do not have cumulative voting rights, preemptive rights or
any conversion or exchange rights. The Trust does not contemplate holding
regular meetings of shareholders to elect Trustees or otherwise. However, the
holders of 10% or more of the outstanding shares may by written request require
a meeting to consider the removal of Trustees by a vote of two-thirds of the
shares then outstanding cast in person or by proxy at such meeting.
 
  The Trustees may amend the Declaration of Trust (including with respect to any
series) in any manner without shareholder approval, except that the Trustees may
not adopt any amendment adversely affecting the rights of shareholders of any
series without approval by a majority of the shares of each affected series
present at a meeting of shareholders (or such higher vote as may be required by
the Investment Company Act of 1940, as amended (the "1940 Act") or other
applicable law) and except that the Trustees cannot amend the Declaration of
Trust to impose any liability on shareholders, make any assessment on shares or
impose liabilities on the Trustees without approval from each affected
shareholder or Trustee, as the case may be.
 
  Statements contained in this Statement of Additional Information as to the
contents of any contract or other document referred to are not necessarily
complete, and, in each instance, reference is made to the copy of such contract
or other document filed as an exhibit to the Registration Statement of which
this Statement of Additional Information forms a part, each such statement being
qualified in all respects by such reference.
 
                      INVESTMENT POLICIES AND RESTRICTIONS
 
  The investment objective of the Fund is set forth in the Prospectus under the
caption "Investment Objective and Policies." There can be no assurance that the
Fund will achieve its investment objective.
 
                                       B-2
<PAGE>   821
 
  Fundamental investment restrictions limiting the investments of the Fund
provide that the Fund may not:
 
   
   1. Invest more than 25% of its assets in a single industry; however, as
      described in the Prospectus, the Fund may from time to time invest more
      than 25% of its assets in a particular segment of the municipal bond
      market; however, the Fund will not invest more than 25% of its assets in
      industrial development bonds in a single industry, except that the Fund
      may purchase securities of other investment companies to the extent
      permitted by (i) the 1940 Act, as amended from time to time, (ii) the
      rules and regulations promulgated by the SEC under the 1940 Act, as
      amended from time to time, or (iii) an exemption or other relief from the
      provisions of the 1940 Act.
    
 
   2. Borrow money, except from banks for temporary purposes and then in amounts
      not in excess of 5% of the total asset value of the Fund, or mortgage,
      pledge, or hypothecate any assets except in connection with a borrowing
      and in amounts not in excess of 10% of the total asset value of the Fund.
      Borrowings may not be made for investment leverage, but only to enable the
      Fund to satisfy redemption requests where liquidation of portfolio
      securities is considered disadvantageous or inconvenient. In this
      connection, the Fund will not purchase portfolio securities during any
      period that such borrowings exceed 5% of the total asset value of the
      Fund. Notwithstanding this investment restriction, the Fund may enter into
      when issued and delayed delivery transactions as described in the
      Prospectus.
 
   3. Make loans of money or property to any person, except to the extent the
      securities in which the Fund may invest are considered to be loans and
      except that the Fund may lend money or property in connection with
      maintenance of the value of, or the Fund's interest with respect to, the
      securities owned by the Fund.
 
   4. Buy any securities "on margin." Neither the deposit of initial or
      maintenance margin in connection with hedging transactions nor short term
      credits as may be necessary for the clearance of transactions is
      considered the purchase of a security on margin.
 
   5. Sell any securities "short," write, purchase or sell puts, calls or
      combinations thereof, or purchase or sell interest rate or other financial
      futures or index contracts or related options, except in connection with
      Strategic Transactions in accordance with the requirements of the SEC and
      the Commodity Futures Trading Commission.
 
   6. Act as an underwriter of securities, except to the extent the Fund may be
      deemed to be an underwriter in connection with the sale of securities held
      in its portfolio.
 
   
   7. Make investments for the purpose of exercising control or participation in
      management, except to the extent that exercise by the Fund of its rights
      under agreements related to securities owned by the Fund would be deemed
      to constitute such control or participation, except that the Fund may
      purchase securities of other investment companies to the extent permitted
      by (i) the 1940 Act, as amended from time to time, (ii) the rules and
      regulations promulgated by the SEC under the 1940 Act, as amended from
      time to time, or (iii) an exemption or other relief from the provisions of
      the 1940 Act.
    
 
   
   8. Invest in securities issued by other investment companies except as part
      of a merger, reorganization or other acquisition and extent permitted by
      (i) the 1940 Act, as amended from time to time, (ii) the rules and
      regulations promulgated by the SEC under the 1940 Act, as amended from
      time to time, or (iii) an exemption or other relief form the provisions of
      the 1940 Act.
    
 
   9. Invest in oil, gas or mineral leases or in equity interests in oil, gas,
      or other mineral exploration or development programs, except pursuant to
      the exercise by the Fund of its rights under agreements relating to
      municipal securities.
 
  10. Purchase or sell real estate, commodities or commodity contracts, except
      to the extent the securities the Fund may invest in are considered to be
      interest in real estate, commodities or commodity contracts or to the
      extent the Fund exercises its rights under agreements relating to such
      securities (in which case the Fund may own, hold, foreclose, liquidate or
      otherwise dispose of real estate acquired as a result of a default on a
      mortgage), and except to the extent that Strategic Transactions the Fund
      may engage in are considered to be commodities or commodities contracts.
 
                                       B-3
<PAGE>   822
 
  The Fund may not change any of these investment restrictions nor any
fundamental policy as they apply to the Fund without the approval of the lesser
of (i) more than 50% of the Fund's outstanding shares or (ii) 67% of the Fund's
shares present at a meeting at which the holders of more than 50% of the
outstanding shares are present in person or by proxy. As long as the percentage
restrictions described above are satisfied at the time of the investment or
borrowing, the Fund will be considered to have abided by those restrictions even
if, at a later time, a change in values or net assets causes an increase or
decrease in percentage beyond that allowed.
 
  The Fund generally will not engage in the trading of securities for the
purpose of realizing short-term profits, but it will adjust its portfolio as
deemed advisable in view of prevailing or anticipated market conditions to
accomplish the Fund's investment objectives. For example, the Fund may sell
portfolio securities in anticipation of a movement in interest rates. Frequency
of portfolio turnover will not be a limiting factor if the Fund considers it
advantageous to purchase or sell securities. Portfolio turnover is calculated by
dividing the lesser of purchases or sales of portfolio securities by the monthly
average value of the securities in the portfolio during the year. Securities,
including options, whose maturity or expiration date at the time of acquisition
were one year or less are excluded from such calculation. The Fund anticipates
that its annual portfolio turnover rate will normally be less than 200%.
 
                      ADDITIONAL INVESTMENT CONSIDERATIONS
 
MUNICIPAL SECURITIES
 
  Municipal securities include long-term obligations, which are often called
municipal bonds, as well as shorter term municipal notes, municipal leases, and
tax exempt commercial paper. Under normal market conditions, longer term
municipal securities generally provide a higher yield than shorter term
municipal securities, and therefore the Fund generally expects to be invested
primarily in longer term municipal securities. The Fund will, however, invest in
shorter term municipal securities when yields are greater than yields available
on longer term municipal securities, for temporary defensive purposes and when
redemption requests are expected. The two principal classifications of municipal
bonds are "general obligation" and "revenue" or "special obligation" bonds,
which include "industrial revenue bonds." General obligation bonds are secured
by the issuer's pledge of its faith, credit, and taxing power for the payment of
principal and interest. Revenue or special obligation bonds are payable only
from the revenues derived from a particular facility or class of facilities or,
in some cases, from the proceeds of a special tax or other specific revenue
source such as from the user of the facility being financed.
 
  Also included within the general category of municipal securities are
participations in lease obligations or installment purchase contract obligations
(hereinafter collectively called "lease obligations") of municipal authorities
of entities used to finance the acquisition of equipment and facilities.
Although lease obligations do not constitute general obligations of the
municipality for which the municipality's taxing power is pledged, a lease
obligation is ordinarily backed by the municipality's covenant to budget for,
appropriate and make the payments due under the lease obligation. However,
certain lease obligations contain "non-appropriation" clauses which provide that
the municipality has no obligation to make lease or installment purchase
payments in future years unless money is appropriated for such purpose on a
yearly basis. A risk exists that the municipality will not, or will be unable
to, appropriate money in the future in the event of political changes, changes
in the economic viability of the project, general economic changes or for other
reasons. In addition to the "non-appropriation" risk, these securities represent
a relatively new type of financing that has not yet developed the depth of
marketability associated with more conventional bonds. Although
"non-appropriation" lease obligations are often secured by an assignment of the
lessee's interest in the leased property, management or disposition of the
property in the event of foreclosure could be costly, time consuming and result
in unsatisfactory recoupment of the Fund's original investment. There is no
limitation on the percentage of the Fund's assets that may be invested in
"non-appropriation" lease obligations. In evaluating such lease obligations, the
Adviser will consider such factors as it deems appropriate, which factors may
include (a) whether the lease can be cancelled, (b) the ability of the lease
obligee to direct the sale of the underlying assets, (c) the general
creditworthiness of the lease obligor, (d) the likelihood that the municipality
will discontinue appropriating funding for the leased property in the event such
property is no longer considered essential by the municipality, (e) the legal
recourse of the lease obligee in the event of such a failure to
 
                                       B-4
<PAGE>   823
 
appropriate funding and (f) any limitations which are imposed on the lease
obligor's ability to utilize substitute property or services than those covered
by the lease obligation. The Fund will invest in lease obligations which contain
non-appropriation clauses only if such obligations are rated investment grade,
at the time of investment.
 
  Also included in the term municipal securities are participation certificates
issued by state and local governments or authorities to finance the acquisition
of equipment and facilities. They may represent participations in a lease, an
installment purchase contract, or a conditional sales contract.
 
  The Fund may purchase floating and variable rate demand notes, which are
municipal securities normally having a stated maturity in excess of one year,
but which permit the holder to demand payment of principal at any time, or at
specified intervals. The issuer of such notes normally has a corresponding
right, after a given period, to prepay at its discretion upon notice to the
noteholders the outstanding principal amount of the notes plus accrued interest.
The interest rate on a floating rate demand note is based on a known lending
rate, such as a bank's prime rate, and is adjusted automatically each time such
rate is adjusted. The interest rate on a variable rate demand note is adjusted
automatically at specified intervals.
 
  The Fund also may invest up to 20% of its total assets in variable rate
derivative municipal securities such as inverse floaters whose rates vary
inversely with changes in market rates of interest. When market rates of
interest decrease, the change in value of such securities will have a positive
effect on the net asset value of the Fund and when market rates of interest
increase, the change in value of such securities will have a negative effect on
the net asset value of the Fund. Inverse floaters may pay a rate of interest
determined by applying a multiple to the variable rate. The extent of increases
and decreases in the value of inverse floaters in response to changes in market
rates of interest generally will be larger than comparable changes in the value
of an equal principal amount of a fixed rate municipal security having similar
credit quality, redemption provisions and maturity.
 
  The Fund may also acquire custodial receipts or certificates underwritten by
securities dealers or banks that evidence ownership of future interest payments,
principal payments or both on certain municipal securities. The underwriter of
these certificates or receipts typically purchases municipal securities and
deposit the securities in an irrevocable trust or custodial account with a
custodian bank, which then issues receipts or certificates that evidence
ownership of the periodic unmatured coupon payments and the final principal
payment on the obligations. Although under the terms of a custodial receipt, the
Fund typically would be authorized to assert its rights directly against the
issuer of the underlying obligation, the Fund could be required to assert
through the custodian bank those rights as may exist against the underlying
issuer. Thus, in the event the underlying issuer fails to pay principal or
interest when due, the Fund may be subject to delays, expenses and risks that
are greater than those that would have been involved if the Fund had purchased a
direct obligation of the issuer. In addition, in the event that the trust or
custodial account in which the underlying security has been deposited is
determined to be an association taxable as a corporation, instead of a
non-taxable entity, the yield on the underlying security would be reduced in
recognition of any taxes paid.
 
  The "issuer" of municipal securities generally is deemed to be the
governmental agency, authority, instrumentality or other political subdivision,
or the non-governmental user of a revenue bond-financed facility, the assets and
revenues of which will be used to meet the payment obligations, or the guarantee
of such payment obligations, of the municipal securities.
 
  Although the Fund will invest at least 80% of its assets in municipal
securities rated investment grade at the time of investment, municipal
securities, like other debt obligations, are subject to the risk of non-payment.
The ability of issuers of municipal securities to make timely payments of
interest and principal may be adversely impacted in general economic downturns
and as relative governmental cost burdens are allocated and reallocated among
federal, state and local governmental units. Such non-payment would result in a
reduction of income to the Fund, and could result in a reduction in the value of
the municipal security experiencing non-payment and a potential decrease in the
net asset value of the Fund. Issuers of municipal securities might seek
protection under the bankruptcy laws. In the event of bankruptcy of such an
issuer, the Fund could experience delays and limitations with respect to the
collection of principal and interest on such municipal securities and the Fund
may not, in all circumstances, be able to collect all principal and interest to
which it is entitled. To enforce its rights in the event of a default in the
payment of interest or repayment of
 
                                       B-5
<PAGE>   824
 
principal, or both, the Fund may take possession of and manage the assets
securing the issuer's obligations on such securities, which may increase the
Fund's operating expenses and adversely affect the net asset value of the Fund.
Any income derived from the Fund's ownership or operation of such assets may not
be tax-exempt. In addition, the Fund's intention to qualify as a "regulated
investment company" under the Internal Revenue Code of 1986, as amended (the
"Code"), may limit the extent to which the Fund may exercise its rights by
taking possession of such assets, because as a regulated investment company the
Fund is subject to certain limitations on its investments and on the nature of
its income. Further, in connection with the working out or restructuring of a
defaulted security, the Fund may acquire additional securities of the issuer,
the acquisition of which may be deemed to be a loan of money or property. Such
additional securities should be considered speculative with respect to the
capacity to pay interest or repay principal in accordance with their terms.
 
  The Fund may invest up to 15% of its total assets in illiquid securities,
securities the disposition of which is subject to substantial legal or
contractual restrictions on resale and securities that are not readily
marketable. The sale of restricted and illiquid securities often requires more
time and results in higher brokerage charges or dealer discounts and other
selling expenses than does the sale of securities eligible for trading on
national securities exchanges or in the over-the-counter markets. Restricted
securities may sell at a price lower than similar securities that are not
subject to restrictions on resale. Restricted securities salable among qualified
institutional buyers without restriction pursuant to Rule 144A under the
Securities Act of 1933, as amended, that are determined to be liquid by the
Adviser under guidelines adopted by the Board of Trustees of the Trust (under
which guidelines the Adviser will consider factors such as trading activities
and the availability of price quotations), will not be treated as restricted
securities by the Fund pursuant to such rules. The Fund may, from time to time,
adopt a more restrictive limitation with respect to investment in illiquid and
restricted securities in order to comply with the most restrictive state
securities law, currently 10%. This policy does not include restricted
securities eligible for resale pursuant to Rule 144A under the Securities Act of
1933, as amended, which the Board of Trustees or the Fund's investment adviser
has determined under Board-approved guidelines to be liquid. The Fund's policy
with respect to investment in illiquid and restricted securities is not a
fundamental policy and may be changed by the Board of Trustees, in consultation
with the Adviser, without obtaining shareholder approval.
 
LOWER GRADE MUNICIPAL SECURITIES
 
  In normal circumstances, at least 80% of the Fund's total assets will be
invested in investment grade municipal securities and up to 20% of the Fund's
total assets may be invested in lower grade municipal securities. The amount of
available information about the financial condition of municipal securities
issuers is generally less extensive than that for corporate issuers with
publicly traded securities and the market for municipal securities is considered
to be generally less liquid than the market for corporate debt obligations.
Liquidity relates to the ability of a Fund to sell a security in a timely manner
at a price which reflects the value of that security. As discussed below, the
market for lower grade municipal securities is considered generally to be less
liquid than the market for investment grade municipal securities. Further,
municipal securities in which the Fund may invest include special obligation
bonds, lease obligations, participation certificates and variable rate
instruments. The market for such securities may be particularly less liquid. The
relative illiquidity of some of the Fund's portfolio securities may adversely
affect the ability of the Fund to dispose of such securities in a timely manner
and at a price which reflects the value of such security in the Adviser's
judgment. Although the issuer of some such municipal securities may be obligated
to redeem such securities at face value, such redemption could result in capital
losses to the Fund to the extent that such municipal securities were purchased
by the Fund at a premium to face value. The market for less liquid securities
tends to be more volatile than the market for more liquid securities and market
values of relatively illiquid securities may be more susceptible to change as a
result of adverse publicity and investor perceptions than are the market values
of higher grade, more liquid securities.
 
  The Fund's net asset value will change with changes in the value of its
portfolio securities. Because the Fund will invest primarily in fixed income
municipal securities, the Fund's net asset value can be expected to change as
general levels of interest rates fluctuate. When interest rates decline, the
value of a portfolio invested in fixed income securities can be expected to
rise. Conversely, when interest rates rise, the value of a portfolio invested in
fixed income securities can be expected to decline. Net asset value and market
value may be
 
                                       B-6
<PAGE>   825
 
volatile due to the Fund's investment in lower grade and less liquid municipal
securities. Volatility may be greater during periods of general economic
uncertainty.
 
  The Adviser values the Fund's investments pursuant to guidelines adopted and
periodically reviewed by the Board of Trustees. To the extent that there is no
established retail market for some of the securities in which the Fund may
invest, there may be relatively inactive trading in such securities and the
ability of the Adviser to accurately value such securities may be adversely
affected. During periods of reduced market liquidity and in the absence of
readily available market quotations for securities held in the Fund's portfolio,
the responsibility of the Adviser to value the Fund's securities becomes more
difficult and the Adviser's judgment may play a greater role in the valuation of
the Fund's securities due to the reduced availability of reliable objective
data. To the extent that the Fund invests in illiquid securities and securities
which are restricted as to resale, the Fund may incur additional risks and
costs. Illiquid and restricted securities are particularly difficult to dispose
of.
 
  Lower grade municipal securities generally involve greater credit risk than
higher grade municipal securities. A general economic downturn or a significant
increase in interest rates could severely disrupt the market for lower grade
municipal securities and adversely affect the market value of such securities.
In addition, in such circumstances, the ability of issuers of lower grade
municipal securities to repay principal and to pay interest, to meet projected
financial goals and to obtain additional financing may be adversely affected.
Such consequences could lead to an increased incidence of default for such
securities and adversely affect the value of the lower grade municipal
securities in the Fund's portfolio and thus the Fund's net asset value. The
secondary market prices of lower grade municipal securities are less sensitive
to changes in interest rates than are those for higher rated municipal
securities, but are more sensitive to adverse economic changes or individual
issuer developments. Adverse publicity and investor perceptions, whether or not
based on rational analysis, may also affect the value and liquidity of lower
grade municipal securities.
 
  Yields on the Fund's portfolio securities can be expected to fluctuate over
time. In addition, periods of economic uncertainty and changes in interest rates
can be expected to result in increased volatility of the market prices of the
lower grade municipal securities in the Fund's portfolio and thus in the net
asset value of the Fund. Net asset value and market value may be volatile due to
the Fund's investment in lower grade and less liquid municipal securities.
Volatility may be greater during periods of general economic uncertainty. The
Fund may incur additional expenses to the extent it is required to seek recovery
upon a default in the payment of interest or a repayment of principal on its
portfolio holdings, and the Fund may be unable to obtain full recovery thereof.
In the event that an issuer of securities held by the Fund experiences
difficulties in the timely payment of principal or interest and such issuer
seeks to restructure the terms of its borrowings, the Fund may incur additional
expenses and may determine to invest additional capital with respect to such
issuer or the project or projects to which the Fund's portfolio securities
relate. Recent and proposed legislation may have an adverse impact on the market
for lower grade municipal securities. Recent legislation requires federally-
insured savings and loan associations to divest their investments in lower grade
bonds. Other legislation has been proposed which, if enacted, could have an
adverse impact on the market for lower grade municipal securities.
 
  The Fund will rely on the Adviser's judgment, analysis and experience in
evaluating the creditworthiness of an issue. In this evaluation, the Adviser
will take into consideration, among other things, the issuer's financial
resources, its sensitivity to economic conditions and trends, its operating
history, the quality of the issuer's management and regulatory matters. The
Adviser also may consider, although it does not rely primarily on, the credit
ratings of S&P, Moody's or another NRSRO in evaluating municipal securities.
Such ratings evaluate only the safety of principal and interest payments, not
market value risk. Additionally, because the creditworthiness of an issuer may
change more rapidly than is able to be timely reflected in changes in credit
ratings, the Adviser continuously monitors the issuers of municipal securities
held in the Fund's portfolio. The Fund may, if deemed appropriate by the
Adviser, retain a security whose rating has been downgraded below B- by S&P,
below B3 by Moody's or an equivalent rating by another NRSRO, or whose rating
has been withdrawn.
 
  Because issuers of lower grade municipal securities frequently choose not to
seek a rating of their municipal securities, the Adviser will be required to
determine the relative investment quality of many of the municipal
 
                                       B-7
<PAGE>   826
 
securities in the Fund's portfolio. Further, because the Fund may invest up to
20% of its total assets in these lower grade municipal securities, achievement
by the Fund of its investment objective may be more dependent upon the Adviser's
investment analysis than would be the case if the Fund were investing
exclusively in higher grade municipal securities. The relative lack of financial
information available with respect to issuers of municipal securities may
adversely affect the Adviser's ability to successfully conduct the required
investment analysis.
 
SPECIAL CONSIDERATIONS RELATING TO NEW YORK MUNICIPAL SECURITIES
 
  As described in the Prospectus, except during temporary periods, the Fund will
invest substantially all of its assets in New York municipal securities. In
addition, the specific New York municipal securities in which the Fund will
invest will change from time to time. The Fund is therefore susceptible to
political, economic, regulatory or other factors affecting issuers of New York
municipal securities. The following information constitutes only a brief summary
of a number of the complex factors which may impact issuers of New York
municipal securities and does not purport to be a complete or exhaustive
description of all adverse conditions to which issuers of New York municipal
securities may be subject. Such information is derived from official statements
utilized in connection with the issuance of New York municipal securities, as
well as from other publicly available documents. Such information has not been
independently verified by the Fund, and the Fund assumes no responsibility for
the completeness or accuracy of such information. Additionally, many factors,
including national, economic, social and environmental policies and conditions,
which are not within the control of such issuers, could have an adverse impact
on the financial condition of such issuers. The Fund cannot predict whether or
to what extent such factors or other factors may affect the issuers of New York
municipal securities, the market value or marketability of such securities or
the ability of the respective issuers of such securities acquired by the Fund to
pay interest on or principal of such securities. The creditworthiness of
obligations issued by local New York issuers may be unrelated to the
creditworthiness of obligations issued by the State of New York, and there is no
responsibility on the part of the State of New York to make payments on such
local obligations. There may be specific factors that are applicable in
connection with investment in the obligations of particular issuers located
within New York, and it is possible the Fund will invest in obligations of
particular issuers as to which such specific factors are applicable. However,
the information set forth below is intended only as a general summary and not as
a discussion of any specific factors that may affect any particular issuer of
New York municipal securities.
 
  The portfolio of the Fund may include municipal securities issued by New York
State (the "State"), by its various public bodies (the "Agencies") or by other
entities located within the State, including the City of New York (the "City")
and political subdivisions thereof or their agencies.
 
   
  THE STATE. The State is the third most populous state in the nation (after
California and Texas) and has a relatively high level of personal wealth. The
State's economy is diverse, with a comparatively large share of the nation's
finance, insurance, transportation, communications and services employment, and
a very small share of the nation's farming and mining activity. Like the rest of
the nation, the State has had a declining proportion of its workforce engaged in
manufacturing and an increasing proportion engaged in service industries. The
State's location and its excellent air transport facilities and natural harbors
have made it an important link in international commerce. Travel and tourism
constitute an important part of the economy; in 1995, tourists spent $24.3
billion in the State.
    
 
   
  Historically, State per capita personal income has been significantly higher
that the national average, although the ratio has varied substantially. Because
the City is a regional employment center for a multi-state region, however,
personal income measured on a residence basis may understate the relative
importance of the State to the national economy and the size of the base to
which State taxation applies. In 1994, the State had a per capita personal
income of $25,726, compared to $21,699 for the nation as a whole. According to
data published by the US Bureau of Economic Analysis, during the past ten years,
total personal income in the State rose slightly faster than the national
average only from 1986 through 1988. Personal income was expected to record
moderate gains in 1996 and bonus payments in the securities industry were
expected to increase further from 1995's record level.
    
 
                                       B-8
<PAGE>   827
 
   
  While the State historically has been one of the wealthiest in the nation,
demographic changes have been gradually eroding its relative economic affluence.
Statewide, urban centers have experienced significant changes involving
migration of the more affluent to the suburbs and an influx of generally less
affluent residents. Regionally, the older Northeast cities have suffered because
of the relative success that the South and the West have had in attracting
people and business. Nevertheless, the State's population has grown since 1930,
except for a period of decline during the 1970s and a virtual standstill the
past two years. The City has also faced greater competition as other major
cities have developed financial and business capabilities which make businesses
less dependent on the specialized services traditionally available almost
exclusively in the City.
    
 
   
  The State has for many years had a very high state and local tax burden
relative to other states. In fiscal year 1994, the State assessed per capita
taxes of $1,806 (9th in the nation), compared to a national average of $1,439.
The burden of state and local taxation, in combination with the many other
causes of regional economic dislocation, may have contributed to the decisions
of some businesses and individuals to relocate outside, or not locate within,
the State.
    
 
   
  To stimulate economic growth, the State has developed programs, including the
provision of direct financial assistance, designed to help businesses expand
existing operations located within the State and to attract new businesses to
the State. In addition, the State has provided various tax incentives to
encourage business relocation and expansion. These programs include direct tax
abatements from local property taxes for new facilities (subject to locality
approval) and investment tax credits that are applied against the state
corporation franchise tax. Furthermore, the State has created "economic
development zones" in economically distressed regions of the State. Businesses
in these zones are provided a variety of tax and other incentives to create jobs
and make investments in the zones.
    
 
   
  During the 1982-83 recession, overall economic activity in the State declined
less than that in the nation as a whole. However, from 1987 to 1995, the State's
rate of economic growth was somewhat slower than the rest of the nation. In
particular, during the 1990-91 recession and post-recession period, the economy
of the State, and that of the rest of the Northeast, was more heavily damaged
than that of the nation as a whole and has been slower to recover. The total
employment growth rate in the State has been below the national average since
1987. The unemployment rate in the State dipped below the national rate in the
second half of 1981 and remained lower until 1991; since then, it has been
higher. The national economy has resumed a more robust rate of growth after a
"soft landing" in 1995, with over 11 million jobs added national since early
1992. The State economy has continued to expand, but growth remains somewhat
slower than in the nation. Although the State has added approximately 240,000
jobs since late 1992, employment growth in the State has been hindered during
recent years by significant cutbacks in the computer and instrument
manufacturing, utility, defense and banking industries. Government downsizing
has also moderated these job gains.
    
 
   
  The State Division of Budget ("DOB") forecasts that national economic growth
will continue at a moderate pace through the end of calendar year 1998. The
forecast projects real Domestic Gross National Product (GDP) growth of 2.3
percent in 1997, which is the same rate now estimated for 1996, followed by a
2.4 percent increase in 1998. The growth of nominal GDP is expected to rise from
4.3 percent in 1996 to 4.5 percent in 1997 and 4.8 percent in 1998. The
inflation rate is expected to remain stable at 2.9 percent in 1997 and decrease
to 2.8 percent in 1998. The annual rate of job growth is expected to slow to 1.6
percent in both 1997 and 1998, down from the 2.0 percent increase in 1996.
Growth in personal income and wages are expected to slow accordingly in 1997 and
1998.
    
 
   
  The original forecast of the State's economy anticipated modest expansion
during the first half of calendar 1996, but some slowdown during the second half
of the year. The State has since revised its economic forecast to project that
moderate growth would continue through the second half of 1996 and during 1997,
with employment, wages and incomes continuing their modest rise, followed by a
slight slowing in 1998. Personal income is estimated to have grown by 5.2
percent in 1996, fueled in part by an unusually large increase in financial
sector bonus payments, and is projected to grow 4.5 percent in 1997 and 4.2
percent in 1998. Overall employment growth will continue at a modest rate,
reflecting the moderate growth of the national economy, continued spending
restraint in government and restructuring in the health care, social service and
banking sectors.
    
 
                                       B-9
<PAGE>   828
 
   
  The forecast for continued slow growth, and any resultant impact on the
State's Financial Plans, contains some uncertainties. Stronger-than-expected
gains in employment could lead to a significant improvement in consumption
spending. Investments could also remain robust. Conversely, the prospect of a
continuing deadlock on federal budget deficit reduction or fears of excessively
rapid economic growth could create upward pressures on interest rates. In
addition, the State economic forecast could over- or underestimate the level of
future bonus payments or inflation growth, resulting in forecasted average wage
growth that could differ significantly from actual growth. Similarly, the State
forecast could fail to correctly account for expected declines in government and
banking employment and the direction of employment change that is likely to
accompany telecommunications deregulation.
    
 
   
  THE STATE'S 1996-97 FISCAL YEAR. The State's 1996-97 fiscal year commenced on
April 1, 1996 and ended on March 31, 1997, and is referred to herein as the
1996-97 fiscal year.
    
 
   
  The State's budget for the 1996-97 fiscal year was enacted by the State
Legislature on July 13, 1996, more than three months after the start of the
fiscal year. Prior to adoption of the budget, the Legislature enacted
appropriations for disbursements considered to be necessary for State operations
and other purposes, including necessary appropriations for all State-supported
debt service. The State Financial Plan for the 1996-97 fiscal year was
formulated on July 25, 1996 and is based on the State's budget as enacted by the
Legislature and signed into law by the Governor, as well as actual results for
the first quarter of the current fiscal year. The State Financial Plan is
updated quarterly pursuant to law in July, October and January.
    
 
   
  1996-97 State Financial Plan. The four governmental fund types that comprise
the State Financial Plan are the General Fund, the Special Revenue Funds, the
Capital Projects Funds and the Debt Service Funds. This fund structure adheres
to accounting standards of the Governmental Accounting Standards Board.
    
 
   
  General Fund. The General Fund is the principal operating fund of the State
and is used to account for all financial transactions, except those required to
be accounted for in another fund. It is the State's largest fund and receives
almost all State taxes and other resources not dedicated to particular purposes.
In the State's 1996-97 fiscal year, the General Fund was expected to account for
approximately 47 percent of total governmental-fund disbursements and 71 percent
of total State-funded disbursements. General Fund moneys are also transferred to
other funds, primarily to support certain capital projects and debt service
payments in other fund types. The General Fund is projected to be balanced on a
cash basis for the State's 1996-97 fiscal year. Total receipts and transfers
from other funds are projected to be $33.17 billion, an increase of $365 million
from the prior fiscal year. Total General Fund disbursements and transfers to
other funds are projected to be $33.12 billion, an increase of $444 million from
the total amount disbursed in the prior fiscal year.
    
 
   
  Projected General Fund Receipts. The discussion below summarizes the State's
original projections of General Fund tax revenues and other receipts for the
1996-97 fiscal year. Major statutory changes adopted with the 1996-97 budget
that affected 1996-97 include: tax reductions totaling $83 million, adoption of
a tax amnesty program expected to increase receipts by $110 million and a
variety of measures increasing miscellaneous receipts by approximately $675
million.
    
 
   
  The PERSONAL INCOME TAX is imposed on the income of individuals, estates and
trusts and is based on federal definitions of income and deductions with certain
modifications. In 1995, the State enacted a tax-reduction program designed to
reduce, by 20 percent over three years, receipts from the personal income tax.
The tax had remained substantially unchanged since 1989 as a result of annual
deferrals of tax reductions originally enacted in 1987. The tax-reduction
program was projected to reduce receipts by $2.3 billion in the 1996-97 fiscal
year, compared to tax receipts under the prior rate structure. The maximum rate
was reduced to 7.59375 percent for 1995, from the 7.875 percent in effect
between 1989 and 1994, and is scheduled under current law to be reduced further
to 6.85 percent in 1997 and thereafter. In addition to significant reductions in
overall tax rates, the program also included increases in the standard
deduction, widening tax brackets to increase the income thresholds at which
higher tax rates apply and modification of certain tax credits. The projected
yield of the tax in the State's 1996-97 fiscal year of $17.1 billion would be an
increase of $103 million from reported collections in the State's 1995-96 fiscal
year. The increase reflects both the effects of the tax reductions noted above
and the fact that reported collections in the preceding year were affected by
net refund reserve transactions that depressed collections in that year by $500
million. Without these changes, the yield of the tax
    
 
                                      B-10
<PAGE>   829
 
   
would grow by more than $1.0 billion (7 percent), reflecting liability growth
for the 1996 tax year projected at approximately the same rate. The income base
for the tax was projected to rise approximately 5 percent for the 1996 tax year.
    
 
   
  USER TAXES AND FEES are comprised of three-quarters of the State's four
percent sales and use tax (the balance, one cent, flows to support Local
Government Assistance Corporation ("LGAC") debt service requirements), the
cigarette, alcoholic beverage container and auto rental taxes and a portion of
the motor fuel excise levies. Also included in this category are receipts from
the motor vehicle registration fees and alcoholic beverage license fees. Since
1993-94, a portion of the motor fuel tax and motor vehicle registration fees and
all of the highway use tax have been earmarked for dedicated transportation
funds. Receipts in this category in the 1996-97 fiscal year were expected to
total $6.73 billion, an increase of $97 million from reported 1995-96 results.
Underlying growth in the continuing sales tax base was forecast to be 5 percent,
accounting for the increase in the category as a whole. Projected receipts in
1996-97 were adversely affected by the full-year effects of reductions in the
diesel motor fuel, container and beer taxes adopted in 1995 and by a temporary
reduction of the sales tax on clothing enacted in 1996.
    
 
   
  BUSINESS TAXES include franchise taxes based generally on net income of
general business, bank and insurance corporations, as well as
gross-receipts-based taxes on utilities and gallonage-based petroleum business
taxes. Through 1993, these levies had been subject to a 15 percent surcharge
initially imposed in 1990. Beginning in 1994, the surcharge rate has been phased
out and, for most taxpayers, there will be no surcharge liability for taxable
periods ending in 1997 and thereafter. Total business tax receipts in the
State's 1996-97 fiscal year were projected at $4.62 billion, a decline of $360
million from reported 1995-96 results. The projected decline resulted from the
continuing effects of tax reductions originally enacted in 1994 and 1995, valued
at approximately $300 million more in 1996-97 than in 1995-96, and the
previously scheduled diversion of petroleum business and other tax receipts to
dedicated transportation funds (valued at approximately $130 million more in
1996-97 than in 1995-96). These factors outweighed the modest growth projected
in the bases of the continuing tax structure. Tax reductions enacted in the
preceding two years included, in addition to a reduction in the surcharge rate,
a lowering of the alternative minimum tax rate and a variety of smaller changes
to the tax on general business corporations, as well as several changes to
reduce the burden of the petroleum business tax on selected industries.
    
 
   
  OTHER TAXES include estate, gift and real estate transfer taxes, a tax on
gains from the sale or transfer of certain real estate where the total
consideration exceeds $1 million, a pari-mutuel tax and other minor levies.
Total receipts from this category in the State's 1996-97 fiscal year were
projected at $948 million, $151 million less than in the preceding year. The
estimates reflected pre-1996 legislation reducing the burden of the real
property gains tax and the estate tax as well as legislation enacted in 1996
repealing the real property gains tax (valued at approximately $120 million more
in 1996-97 than in 1995-96) and diversion of real estate transfer tax proceeds
to the Environmental Protection Fund (valued at approximately $44 million more
in 1996-97 than in 1995-96).
    
 
   
  MISCELLANEOUS RECEIPTS include investment income, abandoned property receipts,
medical provider assessments, receipts from public authorities and certain other
license and fee revenues. Receipts in this category in the 1996-97 fiscal year
were expected to total $2.1 billion, an increase of $683 million above the
amount received in the prior fiscal year. This included $481 million in surplus
revenues from the Medical Malpractice Insurance Association ("MMIA") and other
various non-recurring resources. MMIA is a statutorily-created joint
underwriting association of property/casualty insurance companies authorized to
write certain personal liability insurance in the State which provides primary
and excess medical malpractice insurance for medical service providers in the
State. It has been reported that certain health care providers are considering a
challenge to the State's right to these surplus revenues.
    
 
   
  TRANSFERS FROM OTHER FUNDS to the General Fund consist primarily of tax
revenues in excess of debt service requirements, particularly the one cent sales
tax used to support payments to LGAC. In the State's 1996-97 fiscal year, excess
sales tax revenues were projected to be $1.4 billion, $75 million more than the
amount received in the 1995-96 fiscal year. All other transfers were projected
to decrease by $82 million, primarily reflecting the non-recurring transfer of
$117 million from the Mass Transportation Operating Assistance Fund

to the Revenue Accumulation Fund in 1995-96. As a result, total transfers were
expected to be virtually unchanged year-to-year.
    
 
  Projected General Fund Disbursements
 
   
  GRANTS TO LOCAL GOVERNMENTS is the largest category of General Fund
disbursements, and generally accounts for approximately 70 percent of overall
General Fund spending. Disbursements from this category were projected to total
$23.13 billion in the 1996-97 State Financial Plan, an increase of $597 million
(2.6 percent) from 1995-96 levels. Of this amount, approximately $300 million
was attributable to transactions which were not accounted for in a comparable
way in 1995-96, primarily $271 million in spending related to the issuance of
LGAC bonds. This category of the State Financial Plan included $11.27 billion in
aid for elementary, secondary and higher education, accounting for 49 cents of
every dollar spent in this category. On a school year basis, formula-based
elementary and secondary education aid was to increase $217 million from 1995-96
levels. General Fund payments for Medicaid were projected to be $5.29 billion,
virtually unchanged from the level of $5.34 billion in 1995-96 and down from
$5.79 billion in 1994-95. This expected slow growth was due primarily to
continuation of cost containment measures enacted in 1995-96, new reforms
included in the adopted 1996-97 budget and forecasts for lower caseload based
upon actual experience through May 1996. Other social service spending was
forecast to increase by only $7 million to $3.17 billion in 1996-97, down from
$3.34 billion in 1994-95. Remaining disbursements primarily supported
community-based mental hygiene programs, community and public health programs,
local transportation programs and revenue sharing.
    
 
   
  STATE OPERATIONS spending reflects the administrative costs of operating the
State's agencies, including the prison system, mental hygiene institutions, the
State University of New York ("SUNY") system, the Legislature and the court
system. Personal service costs were to account for approximately 76 percent of
the anticipated disbursements in this category in 1996-97. Since January 1995,
the State's workforce had been reduced by about 15,000 positions, with a
decrease of 5,000 positions expected in 1996-97. State employees did not receive
a general salary increase in the 1996-97 fiscal year as part of the collective
bargaining agreements negotiated for the 1995-96 through 1998-99 fiscal years.
Collective bargaining agreements have been ratified by employee bargaining units
representing most State employees subject to such agreements. Negotiations are
ongoing with remaining units. Disbursements for State operations were projected
at $5.82 billion, a decrease of $135 million or 2.3 percent. The lack of growth
in this category reflected the workforce reduction program for 1996-97 that was
to be accomplished primarily through attrition, a continued hiring freeze and
implementation of a retirement incentive program. Most agencies were expected to
spend less in 1996-97 than in 1995-96; however, criminal justice spending was
expected to increase modestly to reflect the impact of stricter sentencing laws.
    
 
   
  GENERAL STATE CHARGES primarily reflect the costs of providing fringe benefits
for State employees, including contributions to pension systems, the employer's
share of social security contributions, employer contributions toward the cost
of health insurance and the costs of providing worker's compensation and
unemployment insurance benefits. This category also reflects certain fixed costs
such as payments in lieu of taxes and payments of judgments against the State or
its public officers. Disbursements in this category were projected at $2.22
billion in the 1996-97 State Financial Plan, an increase of $138 million from
the 1995-96 levels. Fringe benefit costs in 1995-96 were depressed by the
one-time application of more than $100 million in reimbursements traditionally
budgeted in other categories of the Financial Plan. Pension costs were not
expected to increase in 1996-97 assuming savings were achieved as planned from
the refinancing of certain pension liabilities. Other fringe benefit costs
(including unemployment insurance) were expected to decline due to workforce
reductions accomplished primarily through attrition and early retirements.
    
 
   
  DEBT SERVICE to be paid from the General Fund for 1996-97 reflected only the
$10 million interest cost of the State's commercial paper program.
    
 
   
  TRANSFERS TO OTHER FUNDS from the General Fund are made primarily to finance
certain portions of State capital project spending and debt service on long-term
bonds where these costs are not funded from other sources. Transfers were
projected to total $1.94 billion, a decrease of $161 million or 7.7 percent from
1995-96 levels. Transfers in support of capital projects were expected to
decrease $210 million due to the availability of non-recurring revenues which
were to be deposited directly to the Capital Projects Funds in 1996-97 and the
reclassification of economic development programs from capital projects to
grants to local governments.
    
 
                                      B-12
<PAGE>   831
 
   
Transfers in support of debt service were projected to increase $60 million
reflecting prior year bond sales for prisons, housing programs and SUNY. All
other transfers were expected to decrease $11 million from previous year levels.
    
 
   
  CAPITAL PROJECTS paid directly from the General Fund represent pay-as-you-go
capital expenditures for certain youth and environmental projects. This is a new
Financial Plan category created as a part of the adopted 1996-97 budget.
    
 
   
  Non-recurring Resources. The 1996-97 State Financial Plan included actions
affecting the budget outlook for fiscal year 1996-97 and beyond. The DOB
estimated that the 1996-97 State Financial Plan contained actions that provided
non-recurring resources or savings totaling approximately $1.3 billion. These
included the use of $481 million in surplus funds available from MMIA, $134
million in savings from a refinancing of certain pension obligations, $88
million in projected savings from bond refundings and $36 million in surplus
fund transfers. The balance was composed of $314 million in resources carried
forward from the State's 1995-96 fiscal year and various other actions,
including that portion of the proposed tax amnesty program that was projected to
be non-recurring.
    
 
   
  Out-year Projections of Receipts and Disbursements. The State closed projected
budget gaps of $5.0 billion and $3.9 billion for its 1995-96 and 1996-97 fiscal
years, respectively. The 1997-98 gap was projected at $1.44 billion, based on
the Governor's proposed budget of December 1995. As a result of changes made in
the enacted budget, that gap increased but was not expected to be as large as
those faced in the prior two fiscal years. The Governor indicated that he would
close any potential imbalance primarily through General Fund expenditure
reductions without increases in taxes or deferrals of scheduled tax reductions.
    
 
   
  The out-year projection was impacted by a variety of factors. Enacted tax
reductions, which reduced receipts in the 1996-97 fiscal year by an incremental
$2.4 billion, were projected to reduce receipts in the 1997-98 fiscal year by an
additional $2.1 billion. The use of up to $1.3 billion of non-recurring
resources in 1996-97, and the annualized costs of certain program increases in
the 1996-97 enacted budget, added additional pressure in closing the 1997-98
gap.
    
 
   
  Actions undertaken in the State's 1996-97 fiscal year, such as workforce
reductions, health care and education reforms, and strict controls on State
agency spending, were expected to provide larger recurring savings in 1997-98.
Sustained growth in the State's economy and continued declines in welfare
caseload and Medicaid costs will produce additional savings in the 1997-98
Financial Plan. Finally, future federal reforms of welfare and/or Medicaid could
potentially provide savings to the State in fiscal year 1997-98.
    
 
   
  Fund Balances. The 1996-97 opening fund balance of $287 million included $237
million reserved in the Tax Stabilization Reserve Fund ("TSRF"), $41 million on
deposit in the Contingency Reserve Fund ("CRF") and $9 million in the Revenue
Accumulation Fund, which was drawn down for use in the 1996-97 fiscal year. The
projected closing fund balance in the General Fund of $337 million reflected a
balance of $252 million in the TSRF, following an additional payment of $15
million during the year, and a balance of $85 million in the CRF.
    
 
   
  Other Governmental Funds. In addition to the General Fund, the 1996-97 State
Financial Plan included Special Revenue Funds, Capital Projects Funds and Debt
Service Funds which are discussed below. Amounts below do not include other
sources and uses of funds transferred to or from other fund types.
    
 
   
  SPECIAL REVENUE FUNDS are used to account for the proceeds of specific revenue
sources such as federal grants that are legally restricted, either by the
Legislature or outside parties, to expenditures for specified purposes. Activity
in this fund type was expected to comprise approximately 43 percent of total
government funds receipts in the 1996-97 fiscal year, about three-quarters of
which related to federally-funded programs. Projected receipts in this fund type
totaled $28.04 billion, an increase of $2.43 billion (9.5 percent) over the
prior year. Projected disbursements in this fund type totaled $28.51 billion, an
increase of $2.25 billion (8.6 percent) over 1995-96 levels. Disbursements from
federal funds, primarily the federal share of Medicaid and other social services
programs, were projected to total $21.31 billion in the 1996-97 fiscal year.
Remaining projected spending of $7.2 billion primarily reflected aid to SUNY
supported by tuition and dormitory fees, education aid funded from lottery
receipts, operating aid payments to the Metropolitan Transportation
    
 
                                      B-13

Authority ("MTA") funded from the proceeds of dedicated transportation taxes and
costs of a variety of self-supporting programs which deliver services financed
by user fees.
    
 
   
  CAPITAL PROJECTS FUNDS are used to account for the financial resources used
for the acquisition, construction, or rehabilitation of major State capital
facilities and for capital assistance grants to certain local governments or
public authorities. This fund type consists of the Capital Projects Fund, which
is supported by tax receipts transferred from the General Fund, and 37 other
capital funds established to distinguish specific capital construction purposes
supported by other revenues. In the 1996-97 fiscal year, activity in these funds
was expected to comprise 6 percent of total governmental receipts. Total
receipts in this fund type were projected at $3.58 billion. Disbursements from
this fund type were projected to be $3.85 billion, a decrease of $120 million
(3.1 percent) over prior-year levels, due in part to a reclassification of
economic development projects to the category of grants to local governments in
the General Fund. The Dedicated Highway and Bridge Trust Fund (the "Highway
Trust Fund") was the single largest dedicated fund, comprising an estimated $920
million (24 percent) of the activity in this fund type. Total spending for
capital projects was financed through a combination of sources: federal grants
(28 percent), public authority bond proceeds (34 percent), general obligation
bond proceeds (12 percent) and pay-as-you-go revenues (26 percent).
    
 
   
  DEBT SERVICE FUNDS are used to account for the payment of principal of, and
interest on, long-term debt of the State and to meet commitments under
lease-purchase and other contractual-obligation financing arrangements. This
fund type was expected to comprise 4 percent of total governmental fund receipts
and disbursements in the 1996-97 fiscal year. Receipts in these funds in excess
of debt service requirements may be transferred to the General Fund and Special
Revenue Funds, pursuant to law. The Debt Service fund type consists of the
General Debt Service Fund, which is supported primarily by tax receipts
transferred from the General Fund, and other funds established to accumulate
moneys for the payment of debt service. In the 1996-97 fiscal year, total
disbursements in this fund type were projected at $2.58 billion, an increase of
$164 million or 6.8 percent from the prior year. The transfer from the General
Fund of $1.59 billion was expected to finance 62 percent of these payments. The
remaining payments were expected to be financed by pledged revenues, including
$1.83 billion in taxes, $234 million in dedicated fees and $2.35 billion in
patient revenues, including transfers of federal and State reimbursements and
State dedicated taxes. After required impoundment for debt service, $3.7 billion
was expected to be transferred to the General Fund and other funds in support of
State operations. The largest transfer--$1.9 billion--was made to the Special
Revenue Fund type in support of operations of the mental hygiene agencies.
Another $1.4 billion in excess sales taxes was expected to be transferred to the
General Fund, following payment of projected debt service on LGAC bonds.
    
 
   
  1996-97 Financial Plan Revisions. The 1996-97 State Financial Plan was updated
on October 25, 1996 (the "Mid-Year Update") and on January 14, 1997 (the "Third
Quarter Update"). Revisions were made to estimates of both receipts and
disbursements based on (1) updated economic forecasts for both the nation and
the State, (2) an analysis of actual receipts and disbursements during the
elapsed portion of the fiscal year and (3) an assessment of changing program
requirements.
    
 
   
  The 1996-97 General Fund Financial Plan continued to be balanced. The DOB
projected that, prior to taking the actions described hereinafter, the General
Fund Financial Plan would have shown an operating surplus of approximately $1.3
billion. The projected surplus resulted primarily from growth in the underlying
forecast for projected receipts. As compared to the enacted budget, revenues are
expected to increase by more than $1 billion, while disbursements are expected
to fall by $228 million. These changes from the original Financial Plan
projections reflect actual results through December 1996 as well as modified
economic and social services caseload projections for the balance of the 1996-97
fiscal year.
    
 
   
  Actual receipts through the first two quarters of the 1996-97 fiscal year
reflected stronger-than-expected growth in most taxes, with actual receipts
exceeding expectations by $250 million. Based on the revised economic outlook
and these actual receipts, the Mid-Year Update projected an additional $420
million in General Fund receipts for the 1996-97 fiscal year. Most of this
projected increase was in the yield of the personal income tax ($241 million),
with additional increases expected in business taxes ($124 million) and other
tax receipts ($49 million). Projected collections from user taxes and fees were
revised downward slightly ($5 million). Revisions were also made to both
miscellaneous receipts and in transfers from other funds (an aggregate $11
million projected increase). The Third Quarter Update revised the underlying
estimates of General Fund receipts in the Mid-Year Update upward by $566
million, primarily in personal income taxes
    
 
                                      B-14
<PAGE>   833
 
   
and business taxes. However, two transactions offset these projected increases,
producing a projected decline in available General Fund receipts from the
Mid-Year Update. First, in order to make the projected 1996-97 cash surplus
available to help finance 1997-98 spending requirements, $943 million in
personal income tax refund payments (or reserves therefor) were proposed to be
accelerated into 1996-97. This would decrease reported personal income tax
receipts in 1996-97, while increasing available personal income tax receipts in
1997-98, as these funds will no longer be a charge against current revenues in
1997-98. Second, January 1997 implementation of personal income tax withholding
table changes to reflect tax reductions effective January 1, 1997, originally
scheduled for April 1997, will also depresses personal income tax receipts by an
estimated $250 million in 1997. This change lowers withholding rather than
having these monies paid to taxpayers through larger refunds in 1998. As a
result of these transactions, projected available receipts in 1996-97 have been
reduced by $627 million from the Mid-Year Update, despite the increase in the
underlying forecast.
    
 
   
  Mid-Year Update projections in 1996-97 General Fund disbursements were
increased by $120 million, since increased General Fund disbursements for
education were required to replace a projected decrease in lottery receipts.
This modification was shown in the form of an increased transfer of General Fund
monies to the Lottery Fund in the Special Revenue Fund type. The Third Quarter
Update reduced anticipated General Fund disbursements by $348 million, with
changes made in most categories of the Financial Plan. Most of the savings was
attributable to reductions in local assistance spending, primarily due to
significant re-estimates in social services spending to reflect lower caseload
growth, yielding savings of $226 million. Estimated General State Charges were
reduced $76 million to reflect lower pension and fringe benefit costs, including
savings achieved from the refinancing of certain pension liabilities through the
issuance of long-term debt, as planned, and the repayment of that liability to
the State Retirement System. Transfers to the Capital Projects Fund were reduced
$31 million to reflect slower-than-expected capital disbursements for the
balance of the fiscal year, as well as savings from improved interest rates in
the financial markets.
    
 
   
  The General Fund closing balance was expected to be $358 million at the end of
the 1996-97 fiscal year. Of this amount, $317 million would be on deposit in the
TSRF, while another $41 million would remain on deposit in the CRF as a reserve
for litigation or other unbudgeted costs to the Financial Plan. The TSRF had an
opening balance of $237 million, which was to be supplemented by a required
payment of $15 million and an extraordinary deposit of $65 million from surplus
1996-97 monies. The $9 million on deposit in the Revenue Accumulation Fund was
to be drawn down as planned.
    
 
   
  1996-97 Borrowing Plan. The State anticipated that its capital programs would
be financed, in part, through borrowings by the State and public authorities in
the 1996-97 fiscal year. The State expected to issue $411 million in general
obligation bonds (including $153.6 million for purposes of redeeming outstanding
BANs) and $154 million in general obligation commercial paper. The Legislature
also authorized the issuance of up to $101 million in COPs during the 1996-97
fiscal year for equipment purchases.
    
 
   
  Borrowings by other public authorities pursuant to lease-purchase and
contractual-obligation financings for capital programs of the State were
projected to total $2.15 billion, including costs of issuances, reserve funds,
and other costs, net of anticipated refundings and other adjustments for 1996-97
capital projects. Included therein were borrowings by (i) the Dormitory
Authority of the State of New York ("DASNY") for SUNY, The City University of
New York ("CUNY"), health facilities and mental health facilities, (ii) the
Thruway Authority for the Highway Trust Fund and the Consolidated Highway
Improvement Program, (iii) the Urban Development Corporation ("UDC") (doing
business as the Empire State Development Corporation) for prison and youth
facilities, (iv) the Housing Finance Agency ("HFA") for housing programs and (v)
the Environmental Facilities Corporation and other authorities. In addition, the
Legislature authorized DASNY to refinance a $787 million pension obligation of
the State.
    
 
   
  In the 1996 legislative session, the Legislature approved the Governor's
proposal to present to the voters in November 1996 a $1.75 billion State general
obligation bond referendum to finance various environmental improvement and
remediation projects. Since the Clean Water, Clean Air Bond Act was approved by
the voters, the amount of general obligation bonds issued during 1996-97 fiscal
year may have increased above the $411 million originally included in the
1996-97 Borrowing Plan to finance a portion of this new program.
    
 
   
  THE STATE'S 1997-98 FISCAL YEAR. The State's most recent fiscal year commenced
on April 1, 1997 and ends on March 31, 1998, and is referred to herein as the
1997-98 fiscal year. The Governor presented his 1997-98
    
 
                                      B-15
<PAGE>   834
 
   
Executive Budget to the Legislature on January 14, 1997. The Executive Budget
also contains financial projections for the State's 1998-99 and 1999-2000 fiscal
years, detailed estimates of receipts and an updated Capital Plan. It was
expected that the Governor would prepare amendments to his Executive Budget as
permitted under law and that these amendments would be reflected in a revised
Financial Plan to be released on or before February 13, 1997. There can be no
assurance that the Legislature will enact the Executive Budget as proposed by
the Governor into law, or that the State's adopted budget projections will not
differ materially and adversely from the projections set forth herein.
    
 
   
  1997-98 State Financial Plan. The 1997-98 Financial Plan projects balance on a
cash basis in the General Fund. It reflects a continuing strategy of
substantially reduced State spending, including program restructurings,
reductions in social welfare spending and efficiency and productivity
initiatives. Total General Fund receipts and transfers from other funds are
projected to be $32.88 billion, a decrease of $88 million from total receipts
projected in the 1996-97 fiscal year. Total General Fund disbursements and
transfers to other funds are projected to be $32.84 billion, a decrease of $56
million from spending totals projected for the 1996-97 fiscal year. As compared
to the 1996-97 State Financial Plan, the Executive Budget proposes a
year-to-year decline in General Fund spending of 0.2 percent. State funds
spending (i.e., General Fund plus other dedicated funds, with the exception of
federal aid) is projected to grow by 1.2 percent. Spending from All Governmental
Funds (excluding transfers) is proposed to increase by 2.2 percent from the
prior fiscal year.
    
 
   
  The Executive Budget proposes $2.3 billion in actions to balance the 1997-98
Financial Plan. Before reflecting any actions proposed by the Governor to
restrain spending, General Fund disbursements for 1997-98 were projected to grow
by approximately 4 percent because of growth in Medicaid, higher fixed costs
such as pensions and debt service, collective bargaining agreements, inflation
and the loss of non-recurring resources that offset spending in 1996-97. General
Fund receipts were projected to fall by roughly 3 percent due to modest growth
in the State's economy and underlying tax base, the loss of non-recurring
revenues available in 1996-97 and implementation of previously enacted tax
reduction programs.
    
 
   
  The Executive Budget proposes to close this gap between lower revenues and
higher expenses primarily through a series of spending reductions and Medicaid
cost containment measures, the use of a portion of the projected 1996-97 budget
surplus and other actions. The final 1997-98 Financial Plan projects receipts of
$32.88 billion and spending of $32.84 billion, allowing for a deposit of $24
million into the CRF (providing a year-ending CRF reserve of $65 million) and a
required repayment of $15 million to the TSRF.
    
 
   
  Projected General Fund Receipts. The 1997-98 Financial Plan projects General
Fund receipts (including transfers from other funds) of $32.88 billion, a
decrease of $88 million from the projected 1996-97 level. The estimate of taxes
for 1997-98 reflects overall growth in the yield of the tax structures (when
adjusted for tax law and administrative changes) of between 4 and 4.5 percent,
reflecting modest growth in the economy and continued moderate inflation. The
effects of this growth are offset by the impact of previously enacted tax
reductions and new tax cut proposals, which are outlined below.
    
 
   
  The Executive Budget contains several new tax initiatives which are projected
to reduce total receipts by $170 million in 1997-98. First, the Governor has
proposed a School Tax Relief initiative ("STAR"), a multi-year property tax
reduction proposal that, when fully implemented, will provide $1.7 billion in
school property tax savings through the replacement of these local revenues with
dedicated State revenues. The initial year of the STAR program will reduce
personal income tax receipts by $110 million in the 1997-98 Financial Plan.
Second, the Executive Budget proposes to begin eliminating the State portion of
the estate tax by adopting the federal credit for state death taxes and phasing
out the State gift tax over a multi-year period. This proposal will reduce
revenues from these taxes by $10 million in 1997-98, and larger amounts in
future years. Finally, the Governor has proposed an unspecified $50 million tax
reduction program designed to spur private sector job creation in the State. For
Financial Plan purposes, the $50 million is shown as a charge against the
personal income tax.
    
 
   
  Personal income tax collections for 1997-98 are projected to be $17.04
billion, an increase of $471 million from the projected 1996-97 level. This
estimate reflects growth in "constant law" liability (i.e., taxpayer liability
before scheduled or proposed tax reductions) of about 5 percent in 1997,
partially offset by personal income tax reductions already in law, which are
estimated to produce taxpayer savings of almost $4 billion in 1997-98 ($1.7
billion more than in the prior fiscal year), and the proposed STAR program
described above.
    
 
                                      B-16
<PAGE>   835
 
   
  User tax and fee receipts are projected at $7.02 billion in 1997-98, up $255
million from projected 1996-97 levels. Total collections in this category are
dominated by the State sales and use tax, which accounts for 77 percent of total
receipts in the category. The moderate economic expansion experienced in 1996-97
is expected to slow somewhat, producing an estimated growth in the base of the
sales and use tax of 4.2 percent in 1997-98.
    
 
   
  Total business taxes are now projected at $4.76 billion in 1997-98, a decrease
in $65 million from 1996-97 levels. While "constant-law" liability growth is
anticipated to continue in 1997-98, the effect of scheduled tax reductions
taking effect in 1997 (including the elimination of the business tax surcharge)
leads to a year-to-year decline. The business tax decline also reflects the
continuing diversion of business tax receipts into dedicated transportation
funds.
    
 
   
  Other tax receipts are now projected at $850 million, down $191 million from
the estimated 1996-97 level. This decline reflects the dedication of the real
estate transfer tax for support of environmental purposes ($87 million of
receipts from this tax support the Environmental Protection Fund and the balance
supports debt service or the Clean Water/Clean Air Bond Act with any excess
transferred back to the General Fund) and the first full-year impact of the
repeal of the real property gains tax and the initial impact of the proposed
gift and estate tax changes referenced above.
    
 
   
  Miscellaneous receipts, which include license revenues, fee and fine income,
investment income and abandoned property proceeds, as well as the proceeds of
the largest share of the State's medical provider assessment and various
one-time transactions, are estimated to total $1.49 billion in 1997-98, a
decline of $657 million from the prior year. This decline is largely
attributable to the loss of several one-time transactions that contributed
approximately $750 million in receipts in 1996-97.
    
 
   
  Transfers from other funds consist primarily of sales tax revenues in excess
of debt service requirements used to support debt service payments to LGAC.
Projected amounts in this category for 1997-98 total $1.72 billion, an increase
of $99 million from 1996-97.
    
 
   
  Projected General Fund Disbursements. The 1997-98 Financial Plan projects
General Fund disbursements of $32.84 billion, a decrease of $56 million from
projected spending levels for 1996-97.
    
 
   
  Grants to Local Governments constitute approximately 68 percent of all General
Fund spending, and include payments to local governments, non-profit providers
and individuals. Disbursements in this category are projected to decline by $705
million, primarily reflecting proposed reductions in State Medicaid spending of
$579 million. The State's tuition assistance program would also be reduced to
achieve savings of $142 million. General Fund support for school aid would
increase by $293 million on a State fiscal year basis. This category is also
affected by the proposed reclassification of economic development spending
previously reflected in the State operations category ($13 million) and a
further proposed reclassification of higher education debt service payments from
this category to the debt service category of the Financial Plan ($207 million).
    
 
   
  Support for State operations is projected to decline by $615 million to $5.2
billion in 1997-98. Almost all of this decline is attributable to the proposed
transfer of support for SUNY operations from the General Fund to the Special
Revenue Fund type. All General Fund support for SUNY is proposed for transfer
into a single unified fund for SUNY operations. After adjusting for this
proposed change, State operations disbursements increase modestly, reflecting
the costs of previously negotiated salary increases, offset by proposed agency
efficiencies and the continued decline in the size of the State's workforce. The
Executive Budget recommends net reductions of approximately 1,700 positions,
bringing the size of the State workforce to approximately 191,000 by the end of
the 1997-98 fiscal year.
    
 
   
  General State Charges are projected to total $2.29 billion in 1997-98, an
increase of $146 million from 1996-97 projected levels. This change results from
the proposed transfer of SUNY costs described above, which lowers projected
spending in this category by $126 million, an increase in pension-related costs
of $270 million, reflecting the impact of certain non-recurring actions taken in
1996-97 and an increase in costs associated with the amortization of certain
pension liabilities. Health insurance costs, the largest component of this
category, are projected to remain stable from calendar year 1996 to 1997.

  General Fund debt service includes short-term obligations of the State's
commercial paper program and debt service on its long-term bonds, which are
reflected as transfers to the General Debt Service Fund. In fiscal year 1997-98,
projected short-term debt service costs are expected to be $11 million and
transfers in support of long-term debt service are projected to be $1.89
billion, an increase of $314 million. Of the projected long-term debt service
increase, $207 million is attributable to the reclassification of CUNY higher
education spending from Grants to Local Governments to the Debt Service
category, so that this category conforms to debt service levels. Transfers to
the Capital Projects Fund are projected to be $180 million for 1997-98, an
increase of $59 million. This transfer is net of all other resources available
in the Capital Projects Fund and reflects increased General Fund support for
maintenance and rehabilitation of State facilities in order to replace certain
non-recurring revenues available in 1996-97 for this purpose.
    
 
   
  General Fund Closing Balance. The 1997-98 closing fund balance in the General
Fund is projected to be $397 million. After a required deposit of $15 million,
the expected balance of the TSRF will be $332 million at the close of 1997-98.
The remaining General Fund balance reflects a reserve of $65 million in the CRF
(after an additional deposit of $24 million in 1997-98) to provide resources to
finance potential costs associated with litigation against the State. The
closing fund balance excludes amounts on deposit in the Tax Refund Reserve
Account.
    
 
   
  Non-recurring Resources. The DOB estimates that the 1997-98 Financial Plan
includes approximately $66 million in non-recurring resources, comprising 0.4
percent of the General Fund budget. These include $25 million from a refunding
of HFA bonds and $41 million in miscellaneous receipts and revenue transfers.
Recommendations included in the Executive Budget are expected to provide fully
annualized savings in 1998-99 which more than offset the non-recurring resources
used in 1997-98. The 1997-98 Executive Budget also utilizes $943 million of
projected 1996-97 resources to balance the 1997-98 Financial Plan.
    
 
   
  Special Revenue Funds. For 1997-98, the Financial Plan projects disbursements
of $29.46 billion from Special Revenue Funds, an increase of $2.13 billion. This
includes $8.4 billion from Special Revenue Funds containing State revenues and
$21.05 billion from funds containing federal grants, primarily for social
welfare programs.
    
 
   
  The 1997-98 Executive Budget recommends that all SUNY revenues be consolidated
in a single Special Revenue Fund, permitting SUNY more flexibility and control
in the use of its revenues. SUNY's spending from this fund is projected to total
$2.74 billion in 1997-98. The Mass Transportation Operating Assistance Fund and
the Dedicated Mass Transportation Trust Fund, which receive taxes earmarked for
mass transportation programs throughout the State, are projected to have total
disbursements of $1.29 billion in 1997-98. Disbursements also include $1.66
billion in STAR proceeds from a new fund financed by lottery proceeds and
dedicated personal income tax receipts. Proceeds from this fund will be used to
make start-up payments to school districts each year, as well as the local
property tax reduction payments for the STAR program. Disbursements of $660
million from the Disproportionate Share Medicaid Assistance Fund constitute most
of the remaining estimated Special Revenue Funds disbursements for 1997-98.
    
 
   
  Total Federal Special Revenue Fund disbursements are projected at $21.05
billion in 1997-98, an increase of $944 million from the prior year projected
level. Federal Special Revenue Fund projections assume the receipt of $12.16
billion in total federal Medicaid reimbursements and $2.7 billion in federal
reimbursement for the State's welfare programs. Most of the increase in federal
funds is due to increased welfare funding under the new federal welfare block
grant. All other federal spending is projected at $6.19 billion for 1997-98, an
increase of $405 million.
    
 
   
  Capital Projects Funds. Disbursements from the Capital Projects funds in
1997-98 are estimated at $3.93 billion, or $57 million less than 1996-97
projections. The spending plan includes: $2.2 billion in disbursements for the
third year of the five-year $12.7 billion State and local highway and bridge
program, $110 million in spending from the Clean Water/Clean Air Bond Act,
correctional services spending of $251 million and SUNY capital spending of $185
million.
    
 
   
  The share of capital projects to be financed by "pay-as-you-go" resources is
projected to be approximately 24 percent. State-supported bond issuances finance
48 percent of capital projects, with federal grants financing the remaining 28
percent.
    
 
                                      B-18
<PAGE>   837
 
   
  Debt Service Funds. Disbursements from Debt Service Funds are estimated at
$3.02 billion in 1997-98, an increase of $464 million from 1996-97. Of this
increase, $81 million is attributable to transportation bonding for the State
and local highway and bridge programs, which are financed by the Highway Trust
Fund, and $45 million is for the mental hygiene programs financed through the
Mental Health Services Fund. This increase also reflects $262 million in CUNY
senior and community college debt service formerly classified as local
assistance in the General Fund. Debt service for LGAC bonds is projected at $340
million.
    
 
   
  Cash Flow. The projected 1997-98 General Fund cash flow will not depend on
either short-term spring borrowing or the issuance of LGAC bonds. The new-money
bond issuance portion of the LGAC program was completed in 1995-96, and
provisions prohibiting the State from returning to a reliance upon cash flow
manipulation to balance its budget will remain in bond covenants until the LGAC
bonds are retired.
    
 
   
  The 1997-98 cash flow projects substantial closing balances in each quarter of
the fiscal year, with excesses in receipts over disbursements in every quarter
of the fiscal year, and no monthly balance (prior to March) lower than $400
million. The closing fund balance is projected at $397 million. The cash flow
projections assume continuation of legislation enacted in 1996-97 that permits
the State to use balances in the Lottery Fund for cash flow purposes.
    
 
   
  Outyear Projections Of Receipts And Disbursements. General Fund receipts are
projected at $33.02 billion and $33.91 billion for 1998-99 and 1999-2000,
respectively. These projections were prepared on the basis of an economic
forecast of a steadily growing national economy, in an environment of low
inflation and slow employment growth. The forecast for the State's economic
performance likewise is for slow but steady economic growth. The receipt
projections reflect tax reductions proposed in the Executive Budget that will
reduce receipts by an estimated $798 million in 1998-99 and $1.43 billion in
1999-2000. The bulk of previously enacted tax reductions are annualized in
1997-98 and their impact in the out years is largely proportional to projected
growth in the underlying tax liability.
    
 
   
  Disbursements from the General Fund are projected at $34.60 billion in 1998-99
and $35.93 billion in 1999-2000, before assuming additional spending
efficiencies and/or additional federal revenue maximization. Assuming
implementation of proposed cost containment and other actions proposed in the
Executive Budget, annual disbursements for fiscal years 1998-99 and 1999-2000
grow by $1.77 billion and $1.33 billion, respectively. This includes additional
support for school aid pursuant to the new STAR program. Disbursement growth is
higher in 1998-99 in part because an additional payroll date and Medicaid cycle
will come due, adding non-recurring costs of $286 million to that fiscal year.
    
 
   
  It is expected that the State's 1998-99 Financial Plan will reflect a
continuing strategy of substantially reduced State spending, including agency
consolidations, reductions in the State workforce and efficiency and
productivity initiatives. As Medicaid, welfare and other reforms continue to
evolve at both the State and federal level, additional savings are expected to
accrue to the State. As in the past, the State also expects to continue
aggressive efforts to secure federal funds. Therefore, the outyear projections
assume a target of $600 million in savings from these reforms in 1998-99,
growing to $800 million in 1999-2000. It is expected that the Governor will
propose to close these remaining budget imbalances primarily through further
spending reductions.
    
 
   
  GAAP-Basis Financial Plan. The Executive Budget also contains General Fund and
All Governmental Funds Financial Plans prepared in accordance with Generally
Accepted Accounting Principles ("GAAP"). The Financial Plan is projected to be
balanced on a GAAP-basis across two fiscal years, with a projected reduction in
the GAAP deficit of $118 million over the two years. In 1996-97, the General
Fund GAAP Financial Plan shows total revenues of $33.04 billion, total
expenditures of $32.92 billion and net other financing sources and uses of $771
million. The surplus of $886 million primarily reflects an increase in projected
revenues. In addition, actions in the 1996-97 fiscal year that refinanced a
pension liability produced a one-time benefit in the category of "Proceeds from
Financing Arrangements/Advance Refundings." These benefits were offset by
increases in accruals for Medicaid, handicapped education and other programs. In
1997-98, the General Fund GAAP Financial Plan shows a deficit of $768 million,
reflecting the use of the 1996-97 cash surplus to fund 1997-98 liabilities.
Projections reflect total revenues of $31.70 billion, total expenditures of
$32.93 billion and net other financing sources and uses of $469 million.

  Special Considerations. DOB believes that the economic assumptions and
projections of receipts and disbursements accompanying the 1997-98 Executive
Budget are reasonable. However, the economic and financial condition of the
State may be affected by various financial, social, economic and political
factors. Those factors can be very complex, can vary from fiscal year to fiscal
year and are frequently the result of actions taken not only by the State but
also by entities, such as the federal government, that are outside the State's
control. Because of the uncertainty and unpredictability of changes in these
factors, their impact cannot be fully included in the assumptions underlying the
State's projections. There can be no assurance that the State economy will not
experience results that are worse than predicted, with corresponding material
and adverse effects on the State's financial projections.
    
 
   
  To make progress toward addressing recurring budgetary imbalances, the 1997-98
Executive Budget proposes significant actions to align recurring receipts and
disbursements in future fiscal years. However, there can be no assurance that
the Legislature will enact the Governor's proposals or that the State's actions
will be sufficient to preserve budgetary balance or to align recurring receipts
and disbursements in either 1997-98 or future fiscal years.
    
 
   
  In addition, there has been discussion of additional tax reductions, beyond
those reflected in the State's current projections for 1997-98 and the out years
that, if enacted, could make it more difficult to achieve budget balance over
this period. In particular, modifying the State's sales tax treatment of
clothing has been discussed. The State now receives approximately $700 million
annually from taxation on clothing, and localities receive a roughly equivalent
amount.
    
 
   
  Uncertainties with regard to both the economy and potential decisions at the
federal level add further pressure on future budget balance in the State. Risks
to the Financial Plan include either a financial market or broader economic
"correction" during the period, a risk heightened by the relatively lengthy
expansions currently underway. In addition, a normal "forecast error" of one
percentage point in the expected growth rate could raise or lower receipts by
$600 million during the last year of the projection period. Potential changes to
federal tax law could alter the federal definitions of income on which many
State taxes rely. Similarly, the Financial Plan assumes no significant federal
disallowances or other actions which could affect State finances.
    
 
   
  On August 22, 1996, the President signed into law the Personal Responsibility
and Work Opportunity Reconciliation Act of 1996. This federal legislation
fundamentally changed the programmatic and fiscal responsibilities for
administration of welfare programs at the federal, state and local levels. The
new law abolishes the federal Aid to Families with Dependent Children program
(AFDC) and creates a new Temporary Assistance to Needy Families program (TANF)
funded with a fixed federal block grant to states. The new law also imposes
(with certain exceptions) a five-year durational limit on TANF recipients,
requires that virtually all recipients be engaged in work or community service
activities within two years of receiving benefits and limits assistance provided
to certain immigrants and other classes of individuals. States are required to
meet work activity participation targets for their TANF caseload; these
requirements are phased in over time. States that fail to meet these
federally-mandated job participation rates, or that fail to conform with certain
other federal standards, face potential sanctions in the form of a reduced
federal block grant.
    
 
   
  On October 16, 1996, the Governor submitted the State's TANF implementation
plan to the federal government as required under the new federal welfare law. On
December 13, 1996, the State's plan was approved by the federal government.
Legislation will be required to implement the State's TANF plan and the Governor
has introduced legislation necessary to conform with federal law.
    
 
   
  States are required to comply with the new federal welfare reform law no later
than July 1, 1997. There can be no assurances that the State Legislature will
enact welfare reform proposals as submitted by the Governor and as required
under federal law.
    
 
   
  An additional risk to the 1997-98 State Financial Plan arises from the
potential impact of certain litigation now pending against the State, which
could produce adverse effects on the State's projections of receipts and
disbursements. However, DOB believes that certain court decisions discussed in
the section entitled "The State's Litigation" below will not have a material
impact on the current Financial Plan. Specifically, in the case of Tug Buster
Bouchard et al. v. Wetzler, DOB believes that the court's decision, as
interpreted by the State, will reduce tax revenues only by approximately $5
million in 1997-98 and $2 million thereafter.

  THE STATE'S DEBT. For purposes of analyzing the financial condition of the
State, debt of the State and of certain public authorities may be classified as
State-supported debt, which includes general obligation debt of the State and
lease-purchase and contractual obligations of public authorities (and
municipalities) where debt service is paid from State appropriations (including
dedicated-tax sources and other revenues such as patient charges and dormitory
facilities rentals). In addition, a broader classification, referred to as
State-related debt, includes State-supported debt, as well as certain types of
contingent obligations, including moral-obligation financing, certain contingent
contractual-obligation financing arrangements and State-guaranteed debt
described above, where debt service is expected to be paid from other sources
and State appropriations are contingent in that they may be made and used only
under certain circumstances.
    
 
   
  General Obligation Bond Programs. The first type of State-supported debt,
general obligation debt, is currently authorized for three programmatic
categories: transportation, environmental and housing. The State has issued
bonds only in the first two categories in recent years, with the size of the
issues generally decreasing as existing authorizations are diminished. The
amount of general obligation bonds and BANs issued in the 1993-94 through
1995-96 fiscal years, excluding bonds issued to redeem BANs, was $388 million,
$250 million and $333 million, respectively. Transportation-related bonds are
issued for State highway and bridge improvements, aviation, highway and mass
transportation projects and purposes, and rapid transit, rail, canal, port and
waterway programs and projects. Environmental bonds are issued to fund
environmentally-sensitive land acquisitions, air and water quality improvements,
municipal non-hazardous waste landfill closures and hazardous waste site cleanup
projects. As of March 31, 1996, the total amount of outstanding general
obligation debt was $5.05 billion, including $293.6 million in BANs.
    
 
   
  Lease-Purchase and Contractual-Obligation Financing Programs. The second type
of State-supported debt, lease-purchase and contractual-obligation financing
arrangements with public authorities and municipalities, has been used primarily
by the State to finance the State's highway and bridge program, SUNY and CUNY
buildings, health and mental hygiene facilities, prison construction and
rehabilitation and various other State capital projects.
    
 
   
  Other Financing Obligations. The State has utilized and expects to continue to
utilize lease-purchase and contractual-obligation financing arrangements to
finance its capital programs, in addition to authorized general obligation
bonds. Some of the major capital programs financed by lease-purchase and
contractual obligation agreements are highlighted below.
    
 
   
  Transportation. The State Department of Transportation is responsible for the
highway and bridge program which maintains 400,000 lane miles of highways and
7,500 State bridges. Despite $4.1 billion of general obligation bond
authorizations since 1983, of which $3.5 billion has been issued, many of the
bridges, which were built in the 1930's, and the extensive interstate, primary
and urban highway system built in the 1960's have deteriorated and are in need
of increased levels of maintenance.
    
 
   
  Legislation enacted in 1991 established the Highway Trust Fund to provide for
the dedication of a portion of the petroleum business tax and certain other
transportation-related taxes and fees for transportation improvements.
Legislation enacted in 1996 extends the capital program supported by the Highway
Trust Fund through fiscal year 1999-2000. The $11.35 billion plan is expected to
be financed by federal grants (45 percent), general obligation bonds (3 percent)
and the Highway Trust Fund (52 percent). It is expected that about 50 percent of
the Highway Trust Fund financing will be supported by the dedicated taxes on a
pay-as-you-go basis and 50 percent from bonds to be issued by the Thruway
Authority. The 1996 legislation also extended the authorization of the Thruway
Authority to 1999-2000 to finance the local transportation programs, including a
new $350 million program.
    
 
   
  The State has supported the capital plans of the MTA in part by entering into
service contracts relating to certain bonds issued by the MTA. Legislation
adopted in 1992 and 1993 also authorized payments, subject to appropriation, of
a portion of the petroleum business tax from the State's Dedicated Mass
Transportation Trust Fund to the MTA and authorized it to be used as a source of
payment for bonds to be sold by the MTA to support its capital program.
    
 
  Education. The State finances the physical infrastructure of SUNY and CUNY and
their respective community colleges and the State Education Department through
direct State capital spending and through
 
                                      B-21
<PAGE>   840
 
   
financing arrangements with DASNY, paying all capital costs of the senior
colleges and sharing equally with local governments for the community colleges,
except that SUNY dormitories are financed through dormitory fees.
    
 
   
  The 34 SUNY campuses include more than 1,700 classroom, dormitory, library,
athletic and student buildings, of which 68 percent are over 20 years of age.
Together with the 30 SUNY community colleges, the SUNY system serves 300,000
full-time students. The CUNY system is comprised of 11 senior colleges and 6
community colleges that serve approximately 158,000 full-time students.
    
 
   
  Mental Hygiene. The State provides care for its citizens with mental illness,
mental retardation and developmental disabilities, and for those with chemical
dependencies, through the Office of Mental Retardation ("OMR"), the Office of
Substance Abuse Services and the Office of Mental Hygiene ("OMH"). Historically,
this care had been provided at large State institutions, but the State recently
adopted policies that provide institutional care to only the neediest and
provide additional care in community residences. OMR has closed 11 of its 20
developmental centers, with one additional facility planned for closure in
1996-97. OMH has reduced its adult institutional population from 22,000 in 1982
to 8,250, and is currently reviewing its long-term inpatient bed needs and will
update those projections in 1996-97. OMH will continue to require substantial
capital investments to upgrade to federal standards and implement community
facility development as deinstitutionalization continues. Capital investments
for both programs are primarily supported by patient revenues through financing
arrangements with DASNY.
    
 
   
  Corrections. During the 10-year period 1983-92, the State's prison system more
than doubled in size due to the unprecedented increase in demand for prison
space. Today, the system houses approximately 68,000 inmates in over 69
facilities with 3,000 buildings comprising over 32 million square feet. As the
need to build new structures to create capacity abated in the early 1990's, the
focus of the Department of Correctional Services ("DOCS") capital program
shifted from expansion to the increasing need for rehabilitation of existing
facilities. While high priority renovation projects and replacement of
deteriorated structures remains a DOCS capital program priority, the 1996-97
enacted budget contained funding to increase bed capacity through the addition
of 1,500 new beds. This program is financed through lease-purchase financing
arrangements with the UDC.
    
 
   
  Other Programs. The State also uses lease-purchase and contractual-obligation
financing arrangements for hospital capital programs of the Department of Health
(including Roswell Park Cancer Institute and the David Axelrod Institute for
Public Health), the Division for Youth's institutional facilities and Youth
Opportunity Centers, the State's housing programs and various environmental,
economic development and State building programs.
    
 
   
  Local Government Assistance Corporation (LGAC).  In 1990, as part of a State
fiscal reform program, legislation was enacted creating LGAC, a public benefit
corporation empowered to issue long-term obligations to fund certain payments to
local governments traditionally funded through the State's annual seasonal
borrowing. The legislation authorized LGAC to issue its bonds and notes in an
amount not in excess of $4.7 billion (exclusive of certain refunding bonds).
Over a period of years, the issuance of these long-term obligations, which are
to be amortized over no more than 30 years, was expected to eliminate the need
for continued short-term seasonal borrowing. The legislation also dedicated
revenues equal to one-quarter of the four cent State sales and use tax to pay
debt service on these bonds. The legislation also imposed a cap on the annual
seasonal borrowing of the State at $4.7 billion, less net proceeds of bonds
issued by LGAC and bonds issued to provide for capitalized interest, except in
cases where the Governor and the legislative leaders have certified the need for
additional borrowing and provided a schedule for reducing it to the cap. If
borrowing above the cap is thus permitted in any fiscal year, it is required by
law to be reduced to the cap by the fourth fiscal year after the limit was first
exceeded. This provision capping the seasonal borrowing was included as a
covenant with LGAC's bondholders in the resolution authorizing such bonds. As of
June 1995, LGAC had issued bonds and notes to provide net proceeds of $4.7
billion, completing the program. The impact of LGAC's borrowing is that the
State is able to meet its cash flow needs throughout the fiscal year without
relying on short-term seasonal borrowings. The 1996-97 State Financial Plan
includes no seasonal borrowing; this reflects the success of the LGAC program in
permitting the State to accelerate local aid payments from the first quarter of
the current fiscal year to the fourth quarter of the previous fiscal year.

  THE STATE'S RATINGS. As of January 1997, the State's general obligation bonds
were rated A- by Standard & Poor's ("S&P"), A2 by Moody's Investors Service
("Moody's") and A+ by Fitch Investors Service ("Fitch"). The State carries the
lowest general obligation bond rating of any state. There is no assurance that
any particular rating will continue for any given period of time or that any
such rating will not be revised downward or withdrawn entirely if, in the
judgment of the agency originally establishing the rating, circumstances so
warrant.
    
 
   
  Standard & Poor's. On January 13, 1992, S&P lowered its rating on the State's
general obligation bonds to A- from A and continued its negative rating outlook
assessment on State general obligation debt. S&P cited "[c]continued economic
deterioration, chronic operating deficits, mounting GAAP fund balance deficits,
and the legislative statement in seeking permanent and structurally sound fiscal
operations" as factors contributing to the rating reduction. On April 26, 1993,
S&P revised the rating outlook assessment to stable. On February 14, 1994, S&P
raised its rating outlook assessment to positive and, on December 12, 1994,
confirmed its A- rating. S&P's previous ratings were A from March 1990 to
January 1992, AA- from August 1987 to March 1990 and A+ from November 1982 to
August 1987.
    
 
   
  Moody's Investors Service. On January 6, 1992, Moody's lowered its rating on
certain appropriations-backed debt of the State and its agencies from A to Baa1
noting "mounting budget deficits, inability of the legislature and the
administration to reach timely agreement on deficit reduction plans for the
current fiscal year, and protracted weakness in the economy." Previously,
Moody's lowered its rating to A on June 6, 1990, its rating having been A1 since
May 27, 1986. State general obligation, State-guaranteed and LGAC bonds retained
an A rating but were placed under review for possible downgrade. On February 3,
1992, Moody's confirmed its A rating of State general obligation bonds,
asserting that the State's "general credit standing reflects its diverse and
substantial economic base, but this strength is offset by structural imbalance
of state finances and increasing debt levels." On December 12, 1994, Moody's
reconfirmed its A rating on the State's general obligation long-term
indebtedness. On February 11, 1997, Moody's confirmed its rating of the State's
general obligation bonds and, in connection with a policy change at Moody's to
introduce numerical modifiers to its municipal securities ratings, assigned a
rating of A2 to the State's general obligation bonds.
    
 
   
  THE STATE'S LITIGATION. The State is a defendant in numerous legal proceedings
pertaining to matters incidental to the performance of routine governmental
operations. Such litigation includes, but is not limited to, claims asserted
against the State arising from alleged torts, alleged breaches of contracts,
condemnation proceedings and other alleged violations of State and federal laws.
Included in the State's outstanding litigation are a number of cases challenging
the constitutionality or the adequacy and effectiveness of a variety of
significant social welfare programs primarily involving the State's health and
mental hygiene programs. Adverse judgments in these matters generally could
result in injunctive relief coupled with prospective changes in patient care
which could require substantial increased financing of the litigated programs in
the future.
    
 
   
  Tax Law. Aspects of petroleum business taxes are the subject of administrative
claims and litigation. In Tug Buster Bouchard, et al. v. Wetzler (Supreme Court,
Albany County, commenced November 13, 1992), petitioner tugboat corporations,
which purchased fuel out of State and consumed such fuel within the State,
contended that the assessment of the petroleum business tax pursuant to Tax Law
sec.301 to such fuel violated the Commerce Clause of the United States
Constitution. Petitioners contended that the application of Section 301 to the
interstate transaction but not to purchasers who purchased and consumed fuel
within the State discriminated against interstate commerce. By decision dated
November 14, 1996, based upon the State's concession that the challenged
provision was unconstitutional as applied to the petitioners and other similarly
situated vessels, the Court of Appeals affirmed the order of the Appellate
Division, Third Department, dated January 4, 1996, which held that Tax Law
sec.301(a)(1)(ii) (the portion of the petroleum business tax applicable between
1984 and September 1, 1990 to petroleum businesses which import petroleum into
New York State for consumption in the State) was unconstitutional. The State's
motion for reargument, seeking clarification and/or modification of the Court of
Appeals decision, was denied by order dated December 20, 1996.
    
 
   
  Insurance Law. In Trustees of and The Pension, Hospitalization Benefit Plan of

District of New York), plaintiff employee welfare benefit plans sought a
declaratory judgment nullifying, on the ground of federal preemption, provisions
of Section 2807-c of the Public Health Law and implementing regulations which
impose a bad debt and charity care allowance on all hospital bills and a 13
percent surcharge on inpatient bills paid by employee welfare benefit plans.
This case has been dismissed by stipulation and order, by and among the parties,
with prejudice. Two separate proceedings challenge regulations promulgated by
the Superintendent of Insurance establishing excess medical malpractice premium
rates for the 1986-87 through 1995-96 and 1996-97 fiscal years, respectively
(New York State Health Maintenance Organization Conference, Inc., et al. v. Muhl
et. al., Supreme Court, Albany County). Plaintiffs allege that the method of
rate calculation is arbitrary and capricious and excessive, and seek inter alia,
to annul the present rates and to compel the State to refund accumulated
surpluses not actuarially required.
    
 
   
  Lottery. In Trump v. Perlee, et al. (Supreme Court, New York County, commenced
August 1995), petitioners challenged as unconstitutional and sought to enjoin
"Quick Draw," a game of the State Division of the Lottery. Petitioners contended
that Sections 94-a through 94-g of Ch. 2 L. 1995, which authorize "Quick Draw,"
violated Article I sec.9 of the State Constitution. This constitutional
provision bars gambling but allows lotteries operated by the State. Petitioners
contended that "Quick Draw" is not a lottery as contemplated by Article I sec.9.
The trial court found that the petitioners were not entitled to a preliminary
injunction because they failed to demonstrate a likelihood of success on the
merits. The Supreme Court, Appellate Division, First Department unanimously
affirmed the trial court on June 25, 1996.
    
 
   
  Clean Water/Clean Air Bond Act of 1996. In Robert I. Schultz et al. v. The New
York State Executive et. al. (Supreme Court, Albany County, commenced October
16, 1996), plaintiffs challenge the enactment of the Clean Water/Clean Air Bond
Act of 1996 and its implementing legislation (1996 Laws of New York, Chapters
412 and 413). Plaintiffs claim, inter alia, that the Bond Act and its
implementing legislation violate provisions of the State Constitution requiring
that such debt be authorized by law for some single work or purpose distinctly
specified therein and forbidding incorporation of other statutes by reference.
    
 
   
  Retirement System. In McCall, et al. v. State of New York, et al. (commenced
July 5, 1995 in the Supreme Court, Albany County), an action for a declaratory
judgement and injunctive relief, plaintiffs (including the State Comptroller)
contended that certain provisions of Ch. 199 L. 1995 were unconstitutional. Ch.
119 L. 1995 provided enhanced supplemental pension allowances for members of the
state and local employees' retirement systems. Plaintiffs contended that Section
13 of Ch. 119 L. 1995, which provides that money in a Supplemental Reserve Fund
shall be used as a credit in the state's 1995-96 fiscal year against prior State
and local pension contribution requirements, violated Article V sec.7 of the
state Constitution. This constitutional provision bars the diminishment or
impairment of the benefits of membership in the retirement systems. Plaintiffs
also challenged the constitutionality of Section 16 of Ch. 119 L. 1995, which
conditioned the commencement date of the benefit increase on the existence and
outcome of litigation challenging the credit mechanism. The trial court found
both Section 13 and Section 16 unconstitutional. The Supreme Court, Appellate
Division, Third Department, affirmed the unconstitutionality of Section 13 and
affirmed the unconstitutionality of Section 16 to the extent that the payment of
benefits is conditioned solely on the existence or commencement of litigation.
    
 
   
  Medicaid. Several cases have challenged the rationality and the retroactive
application of State regulations recalibrating nursing home Medicaid rates.
Following invalidation of such previous regulations by the Court of Appeals, the
state Department of Health in 1991 promulgated new recalibration regulations, 10
NYCRR sec.86-2.31(a) and (b), for 1989-1991 and 1992 and subsequent rate years,
respectively. In Matter of New York Association of Homes and Services for the
Aging, Inc. v. Commissioner (Supreme Court, Albany County), by decision dated
June 30, 1994, the Court of Appeals held invalid the Department's retroactive
application to rate years 1989 through 1991 of the nursing home Medicaid
reimbursement rate recalibration adjustment set forth in 10 NYCRR
sec.86-2.31(a). In Matter of New York Association of Homes and Services for the
Aging, Inc. v. Commissioner (Supreme Court, Albany County), plaintiffs
challenged the new recalibration regulations for rate years commencing 1992. The
trial court held that the 1992 recalibration regulations were invalid because
they lacked a rational basis. The Supreme Court, Appellate Division, Third
Department, affirmed the trial court on June 22, 1995 in a 3-2 decision where
the dissenting judges concluded that the regulation was entirely reasonable. The
Court of Appeals agreed with the dissenting judges of the Supreme Court and, on
March 21, 1996, reversed and dismissed the petition.

  Contract and Tort Claims. In Inter-Power of New York, Inc. v. State of New
York (commenced November 16, 1994 in the Court of Claims), plaintiff alleges
that by reason of the failure of the State's Department of Environmental
Conservation to provide in a timely manner accurate and complete data, plaintiff
was unable to complete by the projected completion date a cogenerational
facility, and thereby suffered damages.
    
 
   
  NEW YORK CITY. The fiscal health of the State is closely related to the fiscal
health of its localities, particularly the City, which has required and
continues to require significant financial assistance from the State. The City
is the most populous city in the State and in the nation and is the center of
the nation's largest metropolitan area; it accounts for approximately 41% of the
State's population and personal income. The City is headquarters for the
nation's securities business and for a major portion of the nation's major
commercial banks, diversified financial institutions and life insurance
companies. In addition, the City houses the home offices of the three major
radio and television broadcasting networks, most national magazines and a
substantial portion of the nation's book publishers. The City also leads the
nation in the design and manufacture of men's and women's apparel.
    
 
  In February 1975, the UDC, which had approximately $1 billion of outstanding
debt, defaulted on certain of its short-term notes. Shortly after the UDC
default, the City entered a period of financial crisis from which it is only now
emerging. Both the State Legislature and the United States Congress enacted
legislation in response to this crisis. During 1975, the State Legislature (i)
created the Municipal Assistance Corporation for the City of New York ("MAC") to
assist with long-term financing for the City's short-term debt and other cash
requirements and (ii) created the New York State Financial Control Board (the
"Control Board") to review and approve the City's budgets and City four-year
financial plans (the financial plans also apply to certain City-related public
agencies (the "Covered Organizations")). If the City were to experience certain
adverse financial circumstances, including the occurrence or the substantial
likelihood and imminence of the occurrence of an annual operating deficit of
more than $100 million or the loss of access to the public credit markets to
satisfy the City's capital and seasonal financing requirements, the Control
Board would be required by State law to exercise certain powers.
 
   
  The severe financial difficulties encountered by the City in 1975 caused it to
lose access to the public credit market. At that time, the City was incurring
substantial operating deficits and employing financial and accounting practices
which were widely criticized. Since that time, the City benefited substantially
from financial assistance provided through a combination of federal, State and
private measures and the City has extensively revised its financial systems and
accounting practices. Since 1978, the City's annual financial statements have
been required to be prepared in accordance with GAAP and audited by independent
certified public accountants. For each of the 1981 through 1996 fiscal years,
the City achieved balanced operating results as reported in accordance with GAAP
and the City's 1997 fiscal year results are projected to be balanced in
accordance with GAAP. The City was required to close substantial budget gaps in
recent years in order to maintain balanced operating results. There can be no
assurance that the City will continue to maintain a balanced budget as required
by State law without additional tax or other revenue increases or additional
reductions in City services or entitlement programs, which could adversely
affect the City's economic base. The City depends on State aid both to enable
the City to balance its budget and to meet its cash requirements. There can be
no assurance that there will not be reductions in State aid to the City from
amounts currently projected or that State budgets will be adopted by the April 1
statutory deadline or that any such reductions or delays will not have adverse
effects on the City's cash flow or expenditures. In addition, the federal budget
negotiation process could result in a reduction in or a delay in the receipt of
federal grants which could have additional adverse effects on the City's cash
flow or revenues.
    
 
   
  The Financial Plan. Pursuant to the New York State Financial Emergency Act for
The City of New York, the City prepares a four-year annual financial plan, which
is reviewed and revised on a quarterly basis and which includes the City's
capital, revenue and expense projections and outlines proposed gap-closing
programs for years with projected budget gaps. The Mayor is responsible for
preparing the City's four-year financial plan, including the City's current
financial plan for the 1997 through 2000 fiscal years (the "Financial Plan").
The City is required to submit its financial plans to review bodies, including
the Control Board.
    
 
                                      B-25

  On November 14, 1996, the City submitted to the Control Board the Financial
Plan, which relates to the City, the Board of Education ("BOE") and CUNY. The
Financial Plan is a modification to the financial plan submitted to the Control
Board on June 21, 1996 (the "June Financial Plan").
    
 
   
  The June Financial Plan identified actions to close a previously projected gap
of approximately $2.6 billion for the 1997 fiscal year. The proposed actions in
the June Financial Plan for the 1997 fiscal year included (i) agency actions
totaling $1.2 billion, (ii) a revised tax reduction program which would increase
projected tax revenues by $369 million due to the four year extension of the
12.5% personal income tax surcharge and other actions, (iii) savings resulting
from cost containment in entitlement programs to reduce City expenditures and
additional proposed State aid of $75 million, (iv) the assumed receipt of
revenues relating to rent payments for the City's airports, which are currently
the subject of a dispute with the Port Authority of New York and New Jersey (the
"Port Authority"), (v) the sale of the City's television station for $207
million and (vi) pension cost savings totaling $134 million resulting from a
proposed increase in the earnings assumption for pension assets from 8.5% to
8.75%.
    
 
   
  The Financial Plan reflects actual receipts and expenditures and changes in
forecast revenues and expenditures since the June Financial Plan. The Financial
Plan projects revenues and expenditures for 1997 fiscal year balanced in
accordance with GAAP, and projects gaps of $1.2 billion, $2.1 billion and $3.0
billion for the 1998, 1999 and 2000 fiscal years, respectively. Changes since
the June Financial Plan include (i) an increase in projected tax revenues of
$450 million, $120 million, $50 million and $45 million in fiscal years 1997
through 2000, respectively, (ii) a delay in the assumed receipt of $304 million
relating to projected rent payments for the City airports from the 1997 fiscal
year to the 1998 and 1999 fiscal years, and a $34 million reduction in assumed
State and Federal aid for the 1997 fiscal year, (iii) an approximately $200
million increase in projected overtime and other expenditures in each of the
fiscal years 1997 through 2000, (iv) a $70 million increase in expenditures for
BOE in the 1997 fiscal year for school text books, (v) a reduction in projected
pension costs of $34 million, $50 million, $49 million and $47 million in fiscal
years 1997 through 2000, respectively and (vi) additional agency actions
totaling $179 million, $386 million, $473 million and $589 million in fiscal
years 1997 through 2000, including personnel reductions through attrition and
early retirement.
    
 
   
  The City's projections set forth in the Financial Plan are based on various
assumptions and contingencies which are uncertain and which may not materialize.
Changes in major assumptions could significantly affect the City's ability to
balance its budget as required by State law and to meet its annual cash flow and
financing requirements. The Financial Plan assumes (i) approval by the Governor
and the State Legislature of the extension of the 12.5% personal income tax
surcharge, which expired on December 31, 1996 and is projected to provide
revenue of $170 million, $463 million, $492 million and $521 million in the 1997
through 2000 fiscal years, respectively, (ii) collection of the projected rent
payments for the City's airports, totalling $270 million and $180 million in the
1998 and 1999 fiscal years, respectively, which may depend on the successful
completion of negotiations with the Port Authority or the enforcement of the
City's rights under the existing leases thereto through pending legal actions,
(iii) the ability of the New York City Health and Hospitals Corporation ("HHC")
and BOE to identify actions to offset substantial City and State revenue
reductions and the receipt by BOE of additional State aid, (iv) State approval
of the cost containment initiatives and State aid proposed by the City and (v) a
reduction in City funding for labor settlements for certain public authorities
or corporations. Legislation extending the 12.5% personal income tax surcharge
beyond December 31, 1996 was not enacted in the special legislative session held
in December 1996. Such legislation may be enacted in the 1997 State legislative
session. The Financial Plan does not reflect any increased costs which the City
might incur as a result of welfare legislation recently enacted by Congress or
legislation proposed by the Governor, which would, if enacted, implement such
federal welfare legislation. In addition, the economic and financial condition
of the City may be affected by various financial, social, economic and political
factors which could have a material effect on the City.
    
 
   
  Implementation of the Financial Plan is also dependent upon the City's ability
to market its securities successfully. The City's financing program for fiscal
years 1997 through 2000 contemplates the issuance of $9.0 billion of general
obligation bonds and $3.8 billion of bonds to be issued by the proposed New York
City Finance Authority (the "Finance Authority") to finance City capital
projects. The creation of the Finance Authority, which is subject to the
enactment of State legislation, is being proposed as part of the City's effort
    
 
                                      B-26
<PAGE>   845
 
   
to assist in keeping the City's indebtedness within the forecast level of the
constitutional restrictions on the amount of debt the City is authorized to
incur. Indebtedness subject to the constitutional debt limit includes liability
on capital contracts that are expected to be funded with general obligation
bonds, as well as general obligation bonds. The City's projections of total debt
subject to the general debt limit that would be required to be issued to fund
the Updated Ten-Year Capital Strategy published in April 1995 indicates that
projected contracts for capital projects and debt issuance may exceed the
general debt limit by the end of fiscal year 1997 and would exceed the general
debt limit by a substantial amount thereafter, unless legislation is enacted
creating the Finance Authority or other legislative initiatives are identified
and implemented. Depending on a number of factors, including whether the
Legislature is expected to enact legislation creating the Finance Authority or
to take other action that would provide relief under the general debt limit, the
City may find it necessary to curtail its currently defined capital program
before the end of fiscal year 1997 to ensure that there is ongoing capacity to
enter into capital contracts necessary to preserve projects designed to
safeguard health and safety in the City. Without the Finance Authority or other
legislative relief, the City's general obligation financed capital program with
respect to new projects would be virtually brought to a halt during the
Financial Plan period. General obligation borrowing would continue to reimburse
the City's general fund for ongoing costs of existing contractual commitments.
In addition, the City issues revenue and tax anticipation notes to finance its
seasonal working capital requirements. The success of projected public sales of
City bonds and notes and Finance Authority bonds will be subject to prevailing
market conditions and no assurance can be given that such sales will be
completed. If the City were unable to sell its general obligation bonds and
notes or the proposed Finance Authority were unable to sell its bonds, the City
would be prevented from meeting its planned operating and capital expenditures.
Future developments concerning the City and public discussion of such
developments, as well as prevailing market conditions, may affect the market for
outstanding City general obligation bonds and notes.
    
 
   
  In January 1997, the Mayor was expected to publish a Modification (the
"January Modification") to the Financial Plan for the City's 1997 through 2001
fiscal years and a preliminary budget for the City's 1998 fiscal year. The
January Modification will reflect changes since the Financial Plan, including
the City's program to address the currently forecast gap of approximately $1.2
billion in the 1998 fiscal year. The gap-closing program, as proposed in the
Financial Plan, is currently being further developed and is subject to change in
connection with the January Modification. The Governor released the 1997-1998
Executive Budget on January 14, 1997, which will be considered for adoption by
the State Legislature. Based on a preliminary evaluation of currently available
information, the City's Officer of Management and Budget ("OMB") believes that
the reductions in Medicaid reimbursement rates and other entitlement and welfare
initiatives proposed in the 1997-1998 Executive Budget, if approved by the State
Legislature without change, would provide the City with a portion of the $650
million of additional aid and reductions in entitlement costs assumed in the
City's gap-closing program for the 1998 fiscal year. OMB expects that the
January Modification will reflect additional initiatives proposed by the City
relating to reductions in entitlement costs and additional intergovernmental
aid, which would be dependent upon State legislative approval. Certain proposed
cost containment and other initiatives have been previously considered and
rejected by the State Legislature. The nature and extent of the impact on the
City of the State budget, when adopted, is uncertain, and no assurance can be
given that the State actions included in the State adopted budget may not have a
significant adverse impact on the City's budget and its Financial Plan. It can
be expected that the proposals contained in the January Modification to close
the projected budget gap for the 1998 fiscal year will engender substantial
public debate which will continue through the time the budget is scheduled to be
adopted in June 1997.
    
 
  Certain Reports. From time to time, the Control Board staff, MAC, the Office
of the State Deputy Comptroller for the City of New York ("OSDC"), the City
Comptroller and others issue reports and make public statements regarding the
City's financial condition, commenting on, among other matters, the City's
financial plans, projected revenues and expenditures and actions by the City to
eliminate projected operating deficits. Some of these reports and statements
have warned that the City may have underestimated certain expenditures and
overestimated certain revenues and have suggested that the City may not have
adequately provided for future contingencies. Certain of these reports have
analyzed the City's future economic and social conditions and have questioned
whether the City has the capacity to generate sufficient revenues in the future
 
                                      B-27
<PAGE>   846
 
to meet the costs of its expenditure increases and to provide necessary
services. It is reasonable to expect that such reports and statements will
continue to be issued and to engender public comment.
 
   
  On December 10, 1996, the City Comptroller issued a report on the Financial
Plan which concluded that, while the outlook for the 1997 fiscal year appears to
be favorable, the City still faces several years of growing budget gaps for
fiscal years 1998 through 2000. The report noted that the Financial Plan
continues to use non-recurring actions to close current year budget gaps, which
results in new and larger gaps in succeeding years and demonstrates the
continuing nature of the City's long-term financial instability. The report also
noted that the reliance in the Financial Plan on higher tax revenues must be
carefully monitored, since the increase in tax revenues in the 1997 fiscal year
is primarily the result of higher business tax collections related to
improvements on Wall Street, including lower interest rates, stable inflation
and the stock market rally, which have generated larger than projected profits
in the financial services sector. The report notes that the increase in tax
revenues does not appear to be a result of a general strengthening in the City's
overall economy, and may represent only a temporary improvement in the financial
sector.
    
 
   
  With respect to the 1997 fiscal year, the report identified $200 million in
potential risks, which could be more than offset by potential additional
resources, including bond refundings, a reduction in accrued prior year payables
and utilization of the General Reserve, resulting in a potential year-end
surplus of $338 million to $343 million. The principal risks for the 1997 fiscal
year identified in the report include uncertainties connected with BOE,
resulting primarily from projected State aid which has not been appropriated by
the State Legislature, and $25 million relating to projected overtime
expenditures. The report also noted that the City's capital budget includes
risks in the 1997 fiscal year of $777 million, including $607 million in capital
from the proposed sale of the City's water and sewer system.
    
 
   
  With respect to fiscal years 1998 through 2000, the report identified total
budget risks of between $1.84 billion and $1.88 billion for the 1998 fiscal
year, $2.81 billion and $2.89 billion for the 1999 fiscal year and $3.47 billion
and $3.59 billion for fiscal year 2000. These risks include (i) $305 million and
$250 million in assumed payments from the Port Authority in the 1998 and 1999
fiscal years, respectively, relating to the City's claim for back rentals and an
increase in future rentals, part of which are the subject of arbitration, (ii)
risks of between $223 million and $273 million for the 1998 fiscal year, $210
million and $304 million for the 1999 fiscal year and $156 million and $294
million for fiscal year 2000 related to BOE, resulting primarily from
unidentified expenditure reductions and projected increased State aid in fund
increases in enrollment, (iii) a reduction in the reserve for wage increases
related to the City's labor contracts for certain Covered Organizations totaling
$86 million, $207 million and $327 million in fiscal years 1998 through 2000,
respectively, which would result in the Covered Organizations paying such costs,
and which is the subject of ongoing discussions and (iv) the gaps identified in
the Financial Plan. With respect to the gap-closing programs proposed in the
Financial Plan, the report noted that none of these actions is described in
detail and that many of the proposed actions have been unsuccessful in the past,
including proposed unspecified intergovernmental aid and reductions in
entitlement programs, which provide between 40% and 53% of the City's
gap-closing programs for fiscal years 1998 through 2000. The report noted that,
based on the recent trend to reduce or contain spending increases by the federal
and State governments, additional aid may not be realistic, and that assumed
unspecified State and federal actions and entitlement reductions may not be
prudent given the uncertainties of federal welfare reform and the current
condition of the State's finances. The report also noted that the Financial Plan
projects that a greater percentage of the City's operating budget will pay for
debt service costs than at any time since the City emerged from the fiscal
crisis.
    
 
   
  With respect to the City's capital budget for the 1998 through 2000 fiscal
years, the report identified risks of $1.5 billion, $1.7 billion and $1.4
billion, respectively, including the risk that the proposed Finance Authority
may not be approved by the State Legislature.
    
 
   
  On December 12, 1996, the staff of the OSDC issued a report on the Financial
Plan. The report projected budget gaps of $38 million, $1.3 billion, $2.2
billion and $3.0 billion for the 1997 through 2000 fiscal years, respectively,
which slightly exceed the gaps set forth in the Financial Plan for the 1997
through 1999 fiscal years. The report also identified net additional risks of
$229 million, $1.3 billion, $1.2 billion and $1.1 billion for the 1997 through
2000 fiscal years, respectively. The principal additional risks identified in
the report relate to (i) uncertain State education aid and unspecified
expenditure reductions relating to BOE, totaling
    
 
                                      B-28
<PAGE>   847
 
   
$158 million in the 1997 fiscal year and $260 million in each of the 1998, 1999
and 2000 fiscal years, (ii) the receipt of Port Authority lease payments
totaling $305 million and $250 million in the 1998 and 1999 fiscal years,
respectively, which are the subject of arbitration and a renegotiated lease,
(iii) State approval of a four-year extension to the City's personal income tax
surcharge, which would generate revenues of $171 million, $447 million, $478
million and $507 million in the 1997 through 2000 fiscal years, respectively,
(iv) the receipt of $200 million in the 1998 fiscal year in connection with the
proposed sale of the New York Coliseum and (v) anticipated labor cost savings
from removing City funding of the cost of new labor agreements for certain
Covered Organizations, totaling $86 million, $207 million and $327 million in
fiscal years 1998 through 2000, respectively. The report noted that the future
budget gaps result primarily from the cost of labor agreements and medical and
debt service costs, as well as enacted and proposed tax cuts, and that the
projected gap for fiscal year 2000 is the largest the City has ever faced at
this point in the fiscal year planning cycle since 1981. The report further
noted that the City's revenues are subject to profits in the financial sector,
which are volatile, that there is the potential for a significant correction in
the financial markets and the possibility of continued slowing in the national
economy, and that a recession would present significant difficulties for the
City's budget, particularly if it involved a severe correction on Wall Street.
In addition, the report noted that HHC will face more competition, less City
funding and difficult access to long-term credit markets in future years, that
the projections for HHC include optimistic revenue assumptions and do not
specify actions to offset City reductions, and that the City has not addressed
the impact of privatization proposals on HHC in the context of overall changes
in health care or addressed the fiscal impacts of the substantial Medicaid and
welfare changes which will be included in the next State budget.
    
 
   
  On December 17, 1996, the staff of the Control Board issued a report
commenting on the Financial Plan. The report identified risks totaling $286
million, $1.2 billion, $1.3 billion and $1.1 billion for fiscal years 1997
through 2000, respectively. The principal risks identified on the report
included (i) implementation by BOE of various actions, totaling $26 million in
the 1997 fiscal year and approximately $295 million in each of the 1998 through
2000 fiscal years, which include unspecified expenditure reductions and
uncertain State funding, (ii) a reduction in the City's reserve for the cost of
labor settlements with certain Covered Organizations, totaling $86 million, $207
million and $327 million for fiscal years 1998, 1999 and 2000, respectively, by
requiring such Covered Organizations to self-fund recently negotiated collective
bargaining increases, which has met with strong opposition, (iii) revenues from
the proposed extension of the 12.5% personal income tax surcharge, totaling $171
million, $463 million, $492 million and $521 million in the 1997 through 2000
fiscal years, respectively, which requires State legislation, (iv) the receipt
of $305 million and $250 million from the Port Authority in the 1998 and 1999
fiscal years, respectively, which is the subject of arbitration and (v) the
potential for greater than forecast overtime spending totaling $46 million in
the 1997 fiscal year and approximately $100 million in each of the 1998 through
2000 fiscal years. Taking into account the risks identified in the report and
the gaps projected in the Financial Plan, the Control Board projected gaps of
$286 million, $2.5 billion, $3.4 billion and $4.2 billion for the 1997 through
2000 fiscal years, respectively.
    
 
   
  In addition, with respect to non-property tax forecasts, the report noted that
such taxes are expected to increase by 6% in the 1997 fiscal year and between 3%
and 5% in fiscal years 1998 through 2000, and that such forecasts would be too
high if the financial markets drop sharply or the economy goes into recession.
With respect to HHC, the report noted that a number of factors may affect HHC's
ability to achieve financial stability during the term of the Financial Plan,
including overly optimistic assumptions for both revenues and expenditures, the
potential impact that welfare reform and federal Medicaid and Medicare reforms
may have on hospital revenues, the continued decline in utilization and
continuing pressure on Medicaid revenues if the growth of Medicaid managed care
continues. With respect to the impact on the City of recently-enacted federal
welfare legislation, the report noted that the actual fiscal impact on the City
in the long run is currently unquantifiable due to the great number of variables
still to be resolved, including the determination of rules and regulations at
the federal, State and City level, as well as demographics, migration and the
health of the national and local economies. The report further noted that over
the term of the Financial Plan the relative burden that debt service will place
on the operating budget will increase significantly to an average of about 18%
of tax revenues, and expressed concern about whether the City's capital and
financing plans are affordable on a long-term recurring basis. The report
concluded that the Financial Plan does not adequately address the City's large
and growing budget gaps for the 1998 and subsequent fiscal years, which are
indicative of the
    
 
                                      B-29
<PAGE>   848
 
   
City's ongoing structural imbalance generated by a chronic disparity between
recurring spending and revenue growth.
    
 
   
  On October 31, 1996, the IBO released a report assessing the costs that could
be incurred by the City in response to the Personal Responsibility and Work
Opportunity Reconciliation Act of 1996 (the "1996 Welfare Act"), which, among
other things, replaces the AFDC entitlement program with TANF, imposes a
five-year time limit on TANF assistance, requires 50% of states' TANF caseload
to be employed by 2002 and restricts assistance to legal aliens. Assuming
continued moderate economic performance, the IBO report projects that the City's
cost of providing welfare could increase by $33 million in 1999, growing to $269
million by 2002. Moreover, if the requirement that all recipients work after two
years of receiving benefits is enforced, these additional costs could total $723
million in 1999 and approximately $1 billion annually through 2002, reflecting
substantial costs for worker training and supervision of new workers and
increased child care costs. The report further noted that if economic
performance weakened, resulting in an increased number of public assistance
cases, potential costs to the City could substantially increase.
    
 
   
  States are required to develop plans during 1997 to implement the new law. The
report noted that decisions to be made by the State which will have a
significant impact on the City budget include the allocation of block grant
funds between the State and local governments such as the City and the division
between the State and its local governments of welfare costs not funded by the
federal government. For purposes of its report, the IBO assumed that (i) 60% of
block grant funds would be allocated to the City, based on informal indications
from State officials, (ii) the City and the State will continue to equally share
the costs of the Home Relief program and eligibility and benefit levels will
remain unchanged and (iii) the State and City will equally share the
non-federally funded costs of providing assistance through TANF. Moreover, given
the State's history and constitutional requirement to provide for the aid, care
and support of the needy, IBO's analysis assumes that individuals reaching the
five-year time limit on TANF assistance and removed from the TANF program will
be covered by the Home Relief program, and that legal aliens deemed ineligible
for TANF will be covered by the Home Relief program.
    
 
   
  Finally, the report noted that the new welfare law's most significant fiscal
impact is likely to occur in the years 2002 and beyond, reflecting the full
impact of the lifetime limit on welfare participation which only begins to be
felt in 2002 when the first recipients reach the five-year limit and are assumed
to be covered by Home Relief. In addition, the report noted that, given the
constitutional requirement to care for the needy, the 1996 Welfare Act might
well prompt a migration of benefit-seekers into the City, thereby increasing
City welfare expenditures in the long run. The report concluded that the impact
of the 1996 Welfare Act on the City will ultimately depend on the decisions of
State and City officials, the performance of the local economy and the behavior
of thousands of individuals in response to the new system.
    
 
   
  Collective Bargaining Agreements. Substantially all of the City's full-time
employees are members of labor unions. State law requires that all collective
bargaining agreements entered into by the City and the Covered Organizations be
consistent with the City's current financial plan, except for certain awards
arrived at through the impasse procedure of the New York City Collective
Bargaining Law, which can impose a binding settlement.
    
 
   
  The projections for the 1997 through 2000 fiscal years reflect the costs of
the settlements with the United Federation of Teachers ("UFT") and a coalition
of unions headed by District Council 37 of the American Federation of State,
County and Municipal Employees ("District Council 37"), which together represent
approximately two-thirds of the City's workforce, and assume that the City will
reach agreement with its remaining municipal unions under terms which are
generally consistent with such settlements. The settlement provides for a wage
freeze in the first two years, followed by a cumulative effective wage increase
of 11% by the end of the five year period covered by the proposed agreements,
ending in fiscal years 2000 and 2001. Additional benefit increases would raise
the total cumulative effective increase to 13% above present costs. Costs
associated with similar settlements for all City-funded employees would total
$49 million, $459 million and $1.2 billion in the 1997, 1998 and 1999 fiscal
years, respectively, and exceed $2 billion in each fiscal year after the 1999
fiscal year. There can be no assurance that the City will reach an agreement
with the unions that have not yet reached a settlement with the City on the
terms contained in the Financial Plan.

  Legislation passed in February 1996 will place collective bargaining matters
relating to police and firefighters, including impasse proceedings, under the
jurisdiction of the State Public Employment Relations Board ("PERB"), instead of
the New York City Office of Collective Bargaining ("OCB"). OCB considers wage
levels of municipal employees in similar cities in the United States in reaching
its determinations, while PERB's determinations take into account wage levels in
both private and public employment in comparable communities, particularly
within the State. In addition, PERB can approve only two-year contracts, unlike
OCB which can approve longer contracts. For these reasons, among others, PERB
jurisdiction could result in labor settlements which impose higher costs on the
City than those reached under excising procedures. On January 23, 1996, the City
requested the OCB to declare impasse against the Patrolmen's Benevolent
Association and the Uniformed Firefighters Association. In addition, on February
29, 1996, the City commenced an action in the State Supreme Court seeking a
declaratory judgment confirming that OCB, rather than PERB, has jurisdiction
over collective bargaining matters relating to police.
    
 
   
  Outstanding Indebtedness. As of September 30, 1996, the City had $25.099
billion of outstanding net long-term indebtedness and MAC had $3.889 billion of
outstanding net long-term indebtedness.
    
 
   
  Ratings. In 1975, S&P suspended its A rating of City bonds. This suspension
remained in effect until March 1981, at which time the City received an
investment grade rating of BBB from S&P. On July 2, 1985, S&P revised its rating
of City bonds upward to BBB+ and on November 19, 1987, to A-. On July 10, 1995,
S&P revised its rating of the City's General Obligation Bonds downward to BBB+.
On November 25, 1996, S&P issued a report which stated that if the City reached
its debt limit without the ability to issue bonds through other means, it would
cause a deterioration in the City's infrastructure and significant cutbacks in
the capital plan, which would eventually impact the City's economy and revenues
and could have eventual negative credit implications.
    
 
   
  Moody's ratings of City bonds were revised in November 1981 from B (in effect
since 1977) to Ba1, in November 1983 to Baa, in December 1985 to Baa1, in May
1988 to A and again in February 1991 to Baa1.
    
 
   
  Since July 15, 1993, Fitch has rated City bonds A-. On February 28, 1996,
Fitch placed the City's general obligation bonds on FitchAlert with negative
implications. On November 5, 1996, Fitch removed the City's general obligation
bonds from FitchAlert, although Fitch stated that the outlook remains negative.
    
 
   
  Litigation. The City is a defendant in a significant number of lawsuits. Such
litigation includes, but is not limited to, actions commenced and claims
asserted against the City arising out of alleged constitutional violations,
alleged torts, alleged breaches of contracts and other violations of law and
condemnation proceedings. While the ultimate outcome and fiscal impact, if any,
on the City of the proceedings and claims are not currently predictable, adverse
determination in certain of them might have a material adverse effect upon the
City's ability to carry out the Financial Plan. As of June 30, 1996, the City
estimated its potential future liability on account of all outstanding claims to
be approximately $2.8 billion.
    
 
   
  OTHER LOCALITIES. Certain localities outside the City have experienced
financial problems and have requested and received additional State assistance
during the last several State fiscal years. The potential impact on the State of
any future requests by localities for additional assistance is not included in
the projections of the State's receipts and disbursements for the State's
1996-97 fiscal year.
    
 
   
  Fiscal difficulties experienced by the City of Yonkers resulted in the
re-establishment of the Financial Control Board for the City of Yonkers
("Yonkers Board") by the State in 1984. The Yonkers Board is charged with
oversight of the fiscal affairs of Yonkers. Future actions taken by the State to
assist Yonkers could result in increased State expenditures for extraordinary
local assistance.
    
 
   
  Beginning in 1990, the City of Troy experienced a series of budgetary deficits
that resulted in the establishment of a Supervisory Board for the City of Troy
in 1994 (the "Supervisory Board"). The Supervisory Board's powers were increased
in 1995, when Troy MAC was created to help Troy avoid default on certain
obligations. The legislation creating Troy MAC prohibits the City of Troy from
seeking federal bankruptcy protection while Troy MAC bonds are outstanding.
    
 
   
  Seventeen municipalities received extraordinary assistance during the 1996
legislative session through $50 million in special appropriations targeted for
distressed cities.
    
 
                                      B-31

  Municipalities and school districts have engaged in substantial short-term and
long-term borrowings. In 1994, the total indebtedness of all localities in the
State other than the City was approximately $17.7 billion. A small portion
(approximately $82.9 million) of that indebtedness represented borrowing to
finance budgetary deficits and was issued pursuant to State enabling
legislation. State law requires the Comptroller to review and make
recommendations concerning the budgets of those local government units other
than the City authorized by State law to issue debt to finance deficits during
the period that such deficit financing is outstanding. Seventeen localities had
outstanding indebtedness for deficit financing at the close of their fiscal year
ending in 1994.
    
 
   
  From time to time, federal expenditure reductions could reduce, or in some
cases eliminate, federal funding of some local programs and accordingly might
impose substantial increased expenditure requirements on affected localities. If
the State, the City or any of the public authorities were to suffer serious
financial difficulties jeopardizing their respective access to the public credit
markets, the marketability of notes and bonds issued by localities within the
State could be adversely affected. Localities also face anticipated and
potential problems resulting from certain pending litigation, judicial decisions
and long-range economic trends. Long-range potential problems of declining urban
population, increasing expenditures and other economic trends could adversely
affect localities and require increasing State assistance in the future.
    
 
STRATEGIC TRANSACTIONS
 
  The Fund may, but is not required to, utilize various other investment
strategies as described below to hedge various market risks (such as interest
rates and broad or specific market movements) or to manage the effective
maturity or duration of the Fund's fixed-income securities. Such strategies are
generally accepted by modern portfolio managers and are regularly utilized by
many mutual funds and other institutional investors. Techniques and instruments
may change over time as new instruments and strategies are developed or
regulatory changes occur.
 
  In the course of pursuing these investment strategies, the Fund may purchase
and sell derivative instruments such as exchange-listed and over-the-counter put
and call options on securities, fixed-income indices and other financial
instruments, purchase and sell financial futures contracts and options thereon,
enter into various interest rate transactions such as swaps, caps, floors or
collars (collectively, all the above are called "Strategic Transactions").
Strategic Transactions may be used to attempt to protect against possible
changes in the market value of securities held in or to be purchased for the
Fund's portfolio resulting from securities markets fluctuations, to protect the
Fund's unrealized gains in the value of its portfolio securities, to facilitate
the sale of such securities for investment purposes, to manage the effective
maturity or duration of the Fund's portfolio, or to establish a position in the
derivatives markets as a temporary substitute for purchasing or selling
particular securities.
 
  Any or all of these investment techniques may be used at any time and there is
no particular strategy that dictates the use of one technique rather than
another, as use of any Strategic Transaction is a function of numerous variables
including market conditions. The ability of the Fund to utilize these Strategic
Transactions successfully will depend on the Adviser's ability to predict
pertinent market movements, which cannot be assured. The Fund will comply with
applicable regulatory requirements when implementing these strategies,
techniques and instruments. Strategic Transactions involving financial futures
and options thereon will be purchased, sold or entered into only for bona fide
hedging, risk management or portfolio management purposes and not for
speculative purposes.
 
  Strategic Transactions have risks associated with them including possible
default by the other party to the transaction, illiquidity and, to the extent
the Adviser's view as to certain market movements is incorrect, the risk that
the use of such Strategic Transactions could result in losses greater than if
they had not been used. Use of put and call options may result in losses to the
Fund, force the sale or purchase of portfolio securities at inopportune times or
for prices other than current market values, limit the amount of appreciation
the Fund can realize on its investments or cause the Fund to hold a security it
might otherwise sell. The use of options and futures transactions entails
certain other risks. In particular, the variable degree of correlation between
price movements of futures contracts and price movements in the related
portfolio position of the Fund creates the possibility that losses on the
hedging instrument may be greater than gains in the value of the Fund's
position. In addition, futures and options markets may not be liquid in all
circumstances and certain over-the-
 
                                      B-32
<PAGE>   851
 
counter options may have no markets. As a result, in certain markets, the Fund
might not be able to close out a transaction without incurring substantial
losses, if at all. Although the use of futures and options transactions for
hedging should tend to minimize the risk of loss due to a decline in the value
of the hedged position, at the same time they tend to limit any potential gain
which might result from an increase in value of such position. Finally, the
daily variation margin requirements for futures contracts would create a greater
ongoing potential financial risk than would purchases of options, where the
exposure is limited to the cost of the initial premium. Losses resulting from
the use of Strategic Transactions would reduce net asset value, and possibly
income, and such losses can be greater than if the Strategic Transactions had
not been utilized. Income earned or deemed to be earned, if any, by the Fund
from its Strategic Transactions will generally be taxable income of the Fund.
See "Tax Status" in the Prospectus.
 
  GENERAL CHARACTERISTICS OF OPTIONS.   Put options and call options typically
have similar structural characteristics and operational mechanics regardless of
the underlying instrument on which they are purchased or sold. Thus, the
following general discussion relates to each of the particular types of options
discussed in greater detail below. In addition, many Strategic Transactions
involving options require segregation of Fund assets in special accounts, as
described below under "Use of Segregated and Other Special Accounts."
 
  A put option gives the purchaser of the option, upon payment of a premium, the
right to sell, and the writer the obligation to buy, the underlying security,
commodity, index, or other instrument at the exercise price. For instance, the
Fund's purchase of a put option on a security might be designed to protect its
holdings in the underlying instrument (or, in some cases, a similar instrument)
against a substantial decline in the market value by giving the Fund the right
to sell such instrument at the option exercise price. A call option, upon
payment of a premium, gives the purchaser of the option the right to buy, and
the seller the obligation to sell, the underlying instrument at the exercise
price. The Fund's purchase of a call option on a security, financial future,
index, or other instrument might be intended to protect the Fund against an
increase in the price of the underlying instrument that it intends to purchase
in the future by fixing the price at which it may purchase such instrument. An
American style put or call option may be exercised at any time during the option
period while a European style put or call option may be exercised only upon
expiration or during a fixed period prior thereto. The Fund is authorized to
purchase and sell exchange listed options and over-the-counter options ("OTC
options"). Exchange listed options are issued by a regulated intermediary such
as the Options Clearing Corporation ("OCC"), which guarantees the performance of
the obligations of the parties to such options. The discussion below uses the
OCC as a paradigm, but is also applicable to other financial intermediaries.
 
  With certain exceptions, OCC issued and exchange listed options generally
settle by physical delivery of the underlying security or currency, although in
the future cash settlement may become available. Index options and Eurodollar
instruments are cash settled for the net amount, if any, by which the option is
"in-the-money" (i.e., where the value of the underlying instrument exceeds, in
the case of a call option, or is less than, in the case of a put option, the
exercise price of the option) at the time the option is exercised. Frequently,
rather than taking or making delivery of the underlying instrument through the
process of exercising the option, listed options are closed by entering into
offsetting purchase or sale transactions that do not result in ownership of the
new option.
 
  The Fund's ability to close out its position as a purchaser or seller of an
OCC or exchange listed put or call option is dependent, in part, upon the
liquidity of the option market. Among the possible reasons for the absence of a
liquid option 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 including
reaching daily price limits; (iv) interruption of the normal operations of the
OCC or an exchange; (v) inadequacy of the facilities of an exchange or 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 relevant market for that option on that exchange would cease
to exist, although outstanding options on that exchange would generally continue
to be exercisable in accordance with their terms.
 
                                      B-33
<PAGE>   852
 
  The hours of trading for listed options may not coincide with the hours during
which the underlying financial instruments are traded. To the extent that the
option markets close before the markets for the underlying financial
instruments, significant price and rate movements can take place in the
underlying markets that cannot be reflected in the option markets.
 
  OTC options are purchased from or sold to securities dealers, financial
institutions or other parties ("Counterparties") through direct bilateral
agreement with the Counterparty. In contrast to exchange listed options, which
generally have standardized terms and performance mechanics, all the terms of an
OTC option, including such terms as method of settlement, term, exercise price,
premium, guarantees and security, are set by negotiation of the parties. The
Fund will only sell OTC options that are subject to a buy-back provision
permitting the Fund to require the Counterparty to sell the option back to the
Fund at a formula price within seven days. The Fund expects generally to enter
into OTC options that have cash settlement provisions, although it is not
required to do so.
 
  Unless the parties provide for it, there is no central clearing or guaranty
function in an OTC option. As a result, if the Counterparty fails to make or
take delivery of the security, or other instrument underlying an OTC option it
has entered into with the Fund or fails to make a cash settlement payment due in
accordance with the terms of that option, the Fund will lose any premium it paid
for the option as well as any anticipated benefit of the transaction.
Accordingly, the Adviser must assess the creditworthiness of each such
Counterparty or any guarantor or credit enhancement of the Counterparty's credit
to determine the likelihood that the terms of the OTC option will be satisfied.
The Fund will engage in OTC option transactions only with United States
government securities dealers recognized by the Federal Reserve Bank of New York
as "primary dealers", or broker dealers, domestic or foreign banks or other
financial institutions which have received (or the guarantors of the obligation
of which have received) a short-term credit rating of "A-1" from S&P or "P-1"
from Moody's or an equivalent rating from any other NRSRO. The staff of the SEC
currently takes the position that, in general, OTC options on securities other
than U.S. Government securities purchased by the Fund, and portfolio securities
"covering" the amount of the Fund's obligation pursuant to an OTC option sold by
it (the cost of the sell-back plus the in-the-money amount, if any) are
illiquid, and are subject to the Fund's limitation on investing no more than 15%
of its assets in illiquid securities.
 
  If the Fund sells a call option, the premium that it receives may serve as a
partial hedge, to the extent of the option premium, against a decrease in the
value of the underlying securities or instruments in its portfolio or will
increase the Fund's income. The sale of put options can also provide income.
 
  The Fund may purchase and sell call options on securities, including U.S.
Treasury and agency securities, municipal obligations, mortgage-backed
securities and Eurodollar instruments that are traded on U.S. and foreign
securities exchanges and in the over-the-counter markets. All calls sold by the
Fund must be "covered" (i.e., the Fund must own the securities or futures
contract subject to the call) or must meet the asset segregation requirements
described below as long as the call is outstanding. Even though the Fund will
receive the option premium to help protect it against loss, a call sold by the
Fund exposes the Fund during the term of the option to possible loss of
opportunity to realize appreciation in the market price of the underlying
security or instrument and may require the Fund to hold a security or instrument
which it might otherwise have sold. In the event of exercise of a call option
sold by the Fund with respect to securities not owned by the Fund, the Fund may
be required to acquire the underlying security at a disadvantageous price in
order to satisfy its obligation with respect to the call option.
 
  The Fund may purchase and sell put options on securities including U.S.
Treasury and agency securities, mortgage-backed securities, municipal
obligations and Eurodollar instruments (whether or not it holds the above
securities in its portfolio.) The Fund will not sell put options if, as a
result, more than 50% of the Fund's assets would be required to be segregated to
cover its potential obligations under such put options other than those with
respect to futures and options thereon. In selling put options, there is a risk
that the Fund may be required to buy the underlying security at a
disadvantageous price above the market price.
 
  GENERAL CHARACTERISTICS OF FUTURES.  The Fund may enter into financial futures
contracts or purchase or sell put and call options on such futures as a hedge
against anticipated interest rate or fixed-income market changes, for duration
management and for risk management purposes. Futures are generally bought and
sold on the commodities exchanges where they are listed with payment of initial
and variation margin as described
 
                                      B-34
<PAGE>   853
 
below. The purchase of a futures contract creates a firm obligation by the Fund,
as purchaser, to take delivery from the seller the specific type of financial
instrument called for in the contract at a specific future time for a specified
price (or, with respect to index futures and Eurodollar instruments, the net
cash amount). The sale of a futures contract creates a firm obligation by the
Fund, as seller, to deliver to the buyer the specific type of financial
instrument called for in the contract at a specific future time for a specified
price (or, with respect to index futures and Eurodollar instruments, the net
cash amount). Options on futures contracts are similar to options on securities
except that 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 and
obligates the seller to deliver such option.
 
  The Fund's use of financial futures and options thereon will in all cases be
consistent with applicable regulatory requirements and in particular the rules
and regulations of the Commodity Futures Trading Commission and will be entered
into only for bona fide hedging, risk management (including duration management)
or other portfolio management purposes. Typically, maintaining a futures
contract or selling an option thereon requires the Fund to deposit with a
financial intermediary as security for its obligations an amount of cash or
other specified assets (initial margin) which initially is typically 1% to 10%
of the face amount of the contract (but may be higher in some circumstances).
Additional cash or assets (variation margin) may be required to be deposited
thereafter on a daily basis as the mark to market value of the contract
fluctuates. The purchase of options on financial futures involves payment of a
premium for the option without any further obligation on the part of the Fund.
If the Fund exercises an option on a futures contract it will be obligated to
post initial margin (and potential subsequent variation margin) for the
resulting futures position just as it would for any position. Futures contracts
and options thereon are generally settled by entering into an offsetting
transaction but there can be no assurance that the position can be offset prior
to settlement at an advantageous price nor that delivery will occur.
 
  The Fund will not enter into a futures contract or related option (except for
closing transactions) for other than bona fide hedging purposes if, immediately
thereafter, the sum of the amount of its initial margin and premiums on open
futures contracts and options thereon would exceed 5% of the Fund's total assets
(taken at current value); however, in the case of an option that is in-the-money
at the time of the purchase, the in-the-money amount may be excluded in
calculating the 5% limitation. Certain state securities laws to which the Fund
may be subject may further restrict the Fund's ability to engage in transactions
in futures contracts and related options. The segregation requirements with
respect to futures contracts and options thereon are described below.
 
  OPTIONS ON SECURITIES INDICES AND OTHER FINANCIAL INDICES.  The Fund also may
purchase and sell call and put options on securities indices and other financial
indices and in so doing can achieve many of the same objectives it would achieve
through the sale or purchase of options on individual securities or other
instruments. Options on securities indices and other financial indices are
similar to options on a security or other instrument except that, rather than
settling by physical delivery of the underlying instrument, they settle by cash
settlement, i.e., an option on an index gives the holder the right to receive,
upon exercise of the option, an amount of cash if the closing level of the index
upon which the option is based exceeds, in the case of a call, or is less than,
in the case of a put, the exercise price of the option (except if, in the case
of an OTC option, physical delivery is specified). This amount of cash is equal
to the excess of the closing price of the index over the exercise price of the
option, which also may be multiplied by a formula value. The seller of the
option is obligated, in return for the premium received, to make delivery of
this amount. The gain or loss on an option on an index depends on price
movements in the instruments making up the market, market segment, industry or
other composite on which the underlying index is based, rather than price
movements in individual securities, as is the case with respect to options on
securities.
 
  COMBINED TRANSACTIONS.  The Fund may enter into multiple transactions,
including multiple options transactions, multiple futures transactions and
multiple interest rate transactions and any combination of futures, options and
interest rate transactions ("component" transactions), instead of a single
Strategic Transaction, as part of a single or combined strategy when, in the
opinion of the Adviser, it is in the best interests of the Fund to do so. A
combined transaction will usually contain elements of risk that are present in
each of its component transactions. Although combined transactions are normally
entered into based on the Adviser's judgment that the combined strategies will
reduce risk or otherwise more effectively achieve the desired portfolio
management goal, it is possible that the combination will instead increase such
risks or hinder achievement of the portfolio management objective.
 
                                      B-35
<PAGE>   854
 
  SWAPS, CAPS, FLOORS AND COLLARS.  Among the Strategic Transactions into which
the Fund may enter are interest rate and index swaps and the purchase or sale of
related caps, floors and collars. The Fund expects to enter into these
transactions primarily to preserve a return or spread on a particular investment
or portion of its portfolio, as a duration management technique or to protect
against any increase in the price of securities the Fund anticipates purchasing
at a later date. The Fund intends to use these transactions as hedges and not as
speculative investments and will not sell interest rate caps or floors where it
does not own securities or other instruments providing the income stream the
Fund may be obligated to pay. Interest rate swaps involve the exchange by the
Fund with another party of their respective commitments to pay or receive
interest, e.g., an exchange of floating rate payments for fixed rate payments
with respect to a notional amount of principal. An index swap is an agreement to
swap cash flows on a notional amount based on changes in the values of the
reference indices. The purchase of a cap entitles the purchaser to receive
payments on a notional principal amount from the party selling such cap to the
extent that a specified index exceeds a predetermined interest rate or amount.
The purchase of a floor entitles the purchaser to receive payments on a notional
principal amount from the party selling such floor to the extent that a
specified index falls below a predetermined interest rate or amount. A collar is
a combination of a cap and a floor that preserves a certain return within a
predetermined range of interest rates or values.
 
  The Fund will usually enter into swaps on a net basis, i.e., the two payment
streams are netted out in a cash settlement on the payment date or dates
specified in the instrument, with the Fund receiving or paying, as the case may
be, only the net amount of the two payments. Inasmuch as these swaps, caps,
floors and collars are entered into for good faith hedging purposes, the Adviser
and the Fund believe such obligations do not constitute senior securities under
the 1940 Act and, accordingly, will not treat them as being subject to its
borrowing restrictions. The Fund will not enter into any swap, cap, floor or
collar transaction unless, at the time of entering into such transaction, the
unsecured long-term debt of the Counterparty, combined with any credit
enhancements, is rated at least "A" by S&P or Moody's or has an equivalent
equity rating from an NRSRO or is determined to be of equivalent credit quality
by the Adviser. If there is a default by the Counterparty, the Fund may have
contractual remedies pursuant to the agreements related to the transaction. The
swap market has grown substantially in recent years with a large number of banks
and investment banking firms acting both as principals and agents utilizing
standardized swap documentation. As a result, the swap market has become
relatively liquid. Caps, floors and collars are more recent innovations for
which standardized documentation has not yet been fully developed and,
accordingly, they are less liquid than swaps.
 
   
  USE OF SEGREGATED AND OTHER SPECIAL ACCOUNTS.  Many Strategic Transactions, in
addition to other requirements, require that the Fund segregate liquid
high-grade assets with its custodian to the extent Fund obligations are not
otherwise "covered" through ownership of the underlying security, financial
instrument or currency. In general, either the full amount of any obligation by
the Fund to pay or deliver securities or assets must be covered at all times by
the securities, instruments or currency required to be delivered, or, subject to
any regulatory restrictions, an amount of cash or liquid securities at least
equal to the current amount of the obligation must be segregated with the
custodian. The segregated assets cannot be sold or transferred unless equivalent
assets are substituted in their place or it is no longer necessary to segregate
them. For example, a call option written by the Fund will require the Fund to
hold the securities subject to the call (or securities convertible into the
needed securities without additional consideration) or to segregate liquid
high-grade securities sufficient to purchase and deliver the securities if the
call is exercised. A call option sold by the Fund on an index will require the
Fund to own portfolio securities which correlate with the index or to segregate
liquid assets equal to the excess of the index value over the exercise price on
a current basis. A put option written by the Fund requires the Fund to segregate
liquid securities equal to the exercise price.
    
 
  OTC options entered into by the Fund, including those on securities, financial
instruments or indices and OCC issued and exchange listed index options, will
generally provide for cash settlement. As a result, when the Fund sells these
instruments it will only segregate an amount of assets equal to its accrued net
obligations, as there is no requirement for payment or delivery of amounts in
excess of the net amount. These amounts will equal 100% of the exercise price in
the case of a non cash-settled put, the same as an OCC guaranteed listed option
sold by the Fund, or the in-the-money amount plus any sell-back formula amount
in the case of a cash-settled put or call. In addition, when the Fund sells a
call option on an index at a time when the in-the-money
 
                                      B-36
<PAGE>   855
 
amount exceeds the exercise price, the Fund will segregate, until the option
expires or is closed out, cash or cash equivalents equal in value to such
excess. OCC issued and exchange listed options sold by the Fund other than those
above generally settle with physical delivery, and the Fund will segregate an
amount of assets equal to the full value of the option. OTC options settling
with physical delivery, or with an election of either physical delivery or cash
settlement, will be treated the same as other options settling with physical
delivery.
 
  In the case of a futures contract or an option thereon, the Fund must deposit
initial margin and possible daily variation margin in addition to segregating
assets sufficient to meet its obligation to purchase or provide securities or
currencies, or to pay the amount owed at the expiration of an index- based
futures contract. Such assets may consist of cash, cash equivalents, liquid debt
or equity securities or other acceptable assets.
 
   
  With respect to swaps, the Fund will accrue the net amount of the excess, if
any, of its obligations over its entitlements with respect to each swap on a
daily basis and will segregate an amount of cash or liquid securities having a
value equal to the accrued excess. Caps, floors and collars require segregation
of assets with a value equal to the Fund's net obligation, if any.
    
 
  Strategic Transactions may be covered by other means when consistent with
applicable regulatory policies. The Fund may also enter into offsetting
transactions so that its combined position, coupled with any segregated assets,
equals its net outstanding obligation in related options and Strategic
Transactions. For example, the Fund could purchase a put option if the strike
price of that option is the same or higher than the strike price of a put option
sold by the Fund. Moreover, instead of segregating assets if the Fund held a
futures or forward contract, it could purchase a put option on the same futures
or forward contract with a strike price as high or higher than the price of the
contract held. Other Strategic Transactions may also be offset in combinations.
If the offsetting transaction terminates at the time of or after the primary
transaction no segregation is required, but if it terminates prior to such time,
assets equal to any remaining obligation would need to be segregated.
 
  The Fund's activities involving Strategic Transactions may be limited by the
requirements of the Code for qualification as a regulated investment company.

                  DESCRIPTION OF MUNICIPAL SECURITIES RATINGS
 
  STANDARD & POOR'S RATINGS GROUP--A brief description of the applicable
Standard & Poor's Ratings Group (S&P) rating symbols and their meanings (as
published by S&P) follows:
 
  1. DEBT
 
   
    A S&P corporate or municipal debt rating is a current assessment of the
  creditworthiness of an obligor with respect to a specific obligation. This
  assessment may take into consideration obligors such as guarantors, insurers,
  or lessees.
    
 
    The debt rating is not a recommendation to purchase, sell or hold a
  security, inasmuch as it does not comment as to market price or suitability
  for a particular investor.
 
    The ratings are based on current information furnished by the issuer or
  obtained by S&P from other sources it considers reliable. S&P 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 based on
  other circumstances.
 
     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;
 
     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.
 
                                      B-37
<PAGE>   856
 
<TABLE>
  <S>         <C>
  AAA         Debt rated 'AAA' has the highest rating assigned by S&P.
              Capacity to pay interest and repay principal is extremely
              strong.
 
  AA          Debt rated 'AA' has a very strong capacity to pay interest
              and repay principal and differs from the higher rated issues
              only in small degree.
 
  A           Debt rated 'A' has a strong capacity to pay interest and
              repay principal although it is somewhat more susceptible to
              the adverse effects of changes in circumstances and economic
              conditions than debt in higher rated categories.
 
  BBB         Debt rated 'BBB' is regarded as having an adequate capacity
              to pay interest and repay principal. Whereas it normally
              exhibits adequate protection parameters, adverse economic
              conditions or changing circumstances are more likely to lead
              to a weakened capacity to pay interest and repay principal
              for debt in this category than in higher rated categories.
 
  BB          Debt rated 'BB', 'B', 'CCC', 'CC' and 'C' is regarded as
  B           having predominantly speculative characteristics with
  CCC         respect to capacity to pay interest and repay principal.
  CC          'BB' indicates the least degree of speculation and 'C' the
  C           highest. While such debt will likely have some quality and
              protective characteristics, these are outweighed by large
              uncertainties or large exposures to adverse conditions.
 
  BB          Debt rated 'BB' has less near-term vulnerability to default
              than other speculative issues. However, it faces major
              ongoing uncertainties or exposure to adverse business,
              financial, or economic conditions which could lead to
              inadequate capacity to meet timely interest and principal
              payments. The 'BB' rating category is also used for debt
              subordinated to senior debt that is assigned an actual or
              implied 'BBB-' rating.
 
  B           Debt rated 'B' has a greater vulnerability to default but
              currently has the capacity to meet interest payments and
              principal repayments. Adverse business, financial, or
              economic conditions will likely impair capacity or
              willingness to pay interest and repay principal. The 'B'
              rating category is also used for debt subordinated to senior
              debt that is assigned an actual or implied 'BB' or 'BB-'
              rating.
 
  CCC         Debt rated 'CCC' has a currently identifiable vulnerability
              to default, and is dependent upon favorable business,
              financial, and economic conditions to meet timely payment of
              interest and repayment of principal. In the event of adverse
              business, financial, or economic conditions, it is not
              likely to have the capacity to pay interest and repay
              principal. The 'CCC' rating category is also used for debt
              subordinated to senior debt that is assigned an actual or
              implied 'B' or 'B-' rating.
 
  CC          The rating 'CC' typically is applied to debt subordinated to
              senior debt that is assigned an actual or implied 'CCC'
              rating.
 
  C           The rating 'C' typically is applied to debt subordinated to
              senior debt which is assigned an actual or implied 'CCC-'
              debt rating. The 'C' rating may be used to cover a situation
              where a bankruptcy petition has been filed, but debt service
              payments are continued.
 
  CI          The rating 'CI' is reserved for income bonds on which no
              interest is being paid.
 
  D           Debt rated 'D' is in payment default. The 'D' rating
              category is used when interest payments or principal
              payments are not made on the date due even if the applicable
              grace period has not expired, unless S&P believes that such
              payments will be made during such grace period. The 'D'
              rating also will be used upon the filing of a bankruptcy
              petition if debt service payments are jeopardized.
 
              PLUS (+) or MINUS (-): The ratings from 'AA' to 'CCC' may be
              modified by the addition of a plus or minus sign to show
              relative standing within the major categories.
  C           The letter "c" indicates that the holder's option to tender
              the security for purchase may be canceled under certain
              prestated conditions enumerated in the tender option
              documents.
</TABLE>
 
                                      B-38
<PAGE>   857
  I           The letter "i" indicates the rating is implied. Such ratings
              are assigned only on request to entities that do not have
              specific debt issues to be rated. In addition, implied
              ratings are assigned to governments that have not requested
              explicit ratings for specific debt issues. Implied ratings
              on governments represent the sovereign ceiling or upper
              limit for ratings on specific debt issues of entities
              domiciled in the country.
 
  L           The letter "L" indicates that the rating pertains to the
              principal amount of those bonds to the extent that the
              underlying deposit collateral is federally insured and
              interest is adequately collateralized. In the case of
              certificates of deposit, the letter "L" indicates that the
              deposit, combined with other deposits being held in the same
              right and capacity, will be honored for principal and
              accrued pre-default interest up to the federal insurance
              limits within 30 days after closing of the insured
              institution or, in the event that the deposit is assumed by
              a successor insured institution, upon maturity.
 
  P           The letter "p" indicates that the rating is provisional. A
              provisional rating assumes the successful completion of the
              project being financed by the debt being rated and indicates
              that payment of debt service requirements is largely or
              entirely dependent upon the successful and timely completion
              of the project. This rating, however, while addressing
              credit quality subsequent to completion of the project,
              makes no comment on the likelihood of, or the risk of
              default upon failure of, such completion. The investor
              should exercise his own judgment with respect to such
              likelihood and risk.
 
              *Continuance of the rating is contingent upon S&P's receipt
              of an executed copy of the escrow agreement or closing
              documentation confirming investments and cash flows.
 
  NR          Indicates that no public rating has been requested, that
              there is insufficient information on which to base a rating,
              or that S&P does not rate a particular type of obligation as
              a matter of policy.
 
  DEBT OBLIGATIONS OF ISSUERS OUTSIDE THE UNITED STATES AND ITS TERRITORIES are
rated on the same basis as domestic corporate and municipal issues. The ratings
measure the creditworthiness of the obligor but do not take into account
currency exchange and related uncertainties.
 
  BOND INVESTMENT QUALITY STANDARDS: Under present commercial bank regulations
issued by the Comptroller of the Currency, bonds rated in the top four
categories ("AAA", "AA", "A", "BBB", commonly known as "investment grade"
ratings) are generally regarded as eligible for bank investment. In addition,
the laws of various states governing legal investments impose certain rating or
other standards for obligations eligible for investment by savings banks, trust
companies, insurance companies, and fiduciaries generally.
 
  2. MUNICIPAL NOTES
 
    A S&P note rating reflects the liquidity factors and market-access risks
  unique to notes. Notes maturing in 3 years or less will likely receive a note
  rating. Notes maturing beyond 3 years will most likely receive a long-term
  debt rating.
 
    The following criteria will be used in making that assessment:
 
    -- Amortization schedule (the larger the final maturity relative to other
       maturities, the more likely the issue is to be treated as a note).
 
    -- Source of payment (the more the issue depends on the market for its
       refinancing, the more likely it is to be treated as a note).
 
     The note rating symbols and definitions are as follows:
 
<TABLE>
  <S>         <C>
  SP-1        Strong capacity to pay principal and interest. Issues
              determined to possess very strong characteristics are a plus
              (+) designation.
 
  SP-2        Satisfactory capacity to pay principal and interest, with
              some vulnerability to adverse financial and economic changes
              over the term of the notes.
 
  SP-3        Speculative capacity to pay principal and interest.
</TABLE>
 
                                      B-39
<PAGE>   858
 
  3. COMMERCIAL PAPER
 
    A S&P 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.
 
    Ratings are graded into several categories, ranging from 'A-1' for the
  highest-quality obligations to 'D' for the lowest. These categories are as
  follows:
 
<TABLE>
  <S>         <C>
  A-1         This highest category indicates that the degree of safety
              regarding timely payment is strong. Those issues determined
              to possess extremely strong safety characteristics are
              denoted with a plus sign (+) designation.
 
  A-2         Capacity for timely payment on issues with this designation
              is satisfactory. However, the relative degree of safety is
              not as high as for issues designated 'A-1'.
 
  A-3         Issues carrying this designation have adequate capacity for
              timely payment. They are, however, more vulnerable to the
              adverse effects of changes in circumstances than obligations
              carrying the higher designations.
 
  B           Issues rated 'B' are regarded as having only speculative
              capacity for timely payment.
 
  C           This rating is assigned to short-term debt obligations with
              a doubtful capacity for payment.
 
  D           Debt rated 'D' is in payment default. The 'D' rating
              category is used when interest payments or principal
              payments are not made on the date due, even if the
              applicable grace period has not expired, unless S&P believes
              that such payments will be made during such grace period.
 
  A commercial paper rating is not a recommendation to purchase or sell a
  security. The ratings are based on current information furnished to S&P
  by the issuer or obtained 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.
</TABLE>
 
  4. TAX-EXEMPT DUAL RATINGS
 
  S&P assigns "dual" ratings to all debt issues that have a put option or demand
feature as part of their structure.
 
  The first rating addresses the likelihood of repayment of principal and
interest as due, and the second rating addresses only the demand feature. The
long-term debt rating symbols are used for bonds to denote the long-term
maturity and the commercial paper rating symbols for the put option (for
example, 'AAA/A-1+'). With short-term demand debt, S&P's note rating symbols are
used with the commercial paper rating symbols (for example, 'SP-1+/A-1+').
 
  MOODY'S INVESTORS SERVICE, INC.--A brief description of the applicable Moody's
Investors Service, Inc. ("Moody's") rating symbols and their meanings (as
published by Moody's) follows:
 
  1. LONG-TERM MUNICIPAL BONDS
 
<TABLE>
  <S>         <C>
  AAA         Bonds which are rated Aaa are judged to be of the best
              quality. They carry the smallest degree of investment risk
              and are generally referred to as "gilt edged." Interest
              payments are protected by a large or by an exceptionally
              stable margin and principal is secure. While the various
              protective elements are likely to change, such changes as
              can be visualized are most unlikely to impair the
              fundamentally strong position of such issues.
 
  AA          Bonds which are rated Aa are judged to be of high quality by
              all standards. Together with the Aaa group they comprise
              what are generally known as high grade bonds. They are rated
              lower than the best bonds because margins of protection may
              not be as large as in Aaa securities or fluctuation of
              protective elements may be of greater amplitude or there may
              be other elements present which make the long-term risk
              appear somewhat larger than the Aaa securities.
</TABLE>
 
                                      B-40
<PAGE>   859
   
  A           Bonds which are rated A possess many favorable investment
              attributes and are to be considered as upper-medium-grade
              obligations. Factors giving security to principal and
              interest are considered adequate, but elements may be
              present which suggest a susceptibility to impairment some
              time in the future.
 
  BAA         Bonds which are rated Baa are considered as medium-grade
              obligations, (i.e., they are neither highly protected nor
              poorly secured). Interest payments and principal security
              appear adequate for the present but certain protective
              elements may be lacking or may be characteristically
              unreliable over any great length of time. Such bonds lack
              outstanding investment characteristics and in fact have
              speculative characteristics as well.
 
  BA          Bonds which are rated Ba are judged to have speculative
              elements; their future cannot be considered as well-assured.
              Often the protection of interest and principal payments may
              be very moderate, and thereby not well safeguarded during
              both good and bad times over the future. Uncertainty of
              position characterizes bonds in this class.
 
  B           Bonds which are rated B generally lack characteristics of
              the desirable investment. Assurance of interest and
              principal payments or of maintenance of other terms of the
              contract over any long period of time may be small.
 
  CAA         Bonds which are rated Caa are of poor standing. Such issues
              may be in default or there may be present elements of danger
              with respect to principal or interest.
 
  CA          Bonds which are rated Ca represent obligations which are
              speculative in a high degree. Such issues are often in
              default or have other marked shortcomings.
 
  C           Bonds which are rated C are the lowest rated class of bonds,
              and issues so rated can be regarded as having extremely poor
              prospects of ever attaining any real investment standing.
 
  CON (..)    Bonds for which the security depends upon the completion of
              some act or the fulfillment of some condition are rated
              conditionally and designated with the prefix "Con." followed
              by the rating in parentheses. These are bonds secured by:
              (a) earnings of projects under construction, (b) earnings of
              projects unseasoned in operating experience, (c) rentals
              that begin when facilities are completed, or (d) payments to
              which some other limiting condition attaches the
              parenthetical rating denotes the probable credit stature
              upon completion of construction or elimination of the basis
              of the condition.
 
  (P) (..)    When applied to forward delivery bonds, indicates that the
              rating is provisional pending the delivery of the bonds. The
              rating may be revised prior to delivery if changes occur in
              the legal documents or the underlying credit quality of the
              bonds.
 
  NOTE:       Moody's applies numerical modifiers, 1, 2 and 3 in each
              generic rating classification from AA to B. The modifier 1
              indicates that the company ranks in the higher end of its
              generic rating category; the modifier 2 indicates a
              mid-range ranking; and the modifier 3 indicates that the
              company ranks in the lower end of its generic rating
              category.
 
    
 
  2. SHORT-TERM EXEMPT NOTES
 
    Moody's ratings for state and municipal short-term obligations will be
  designated Moody's Investment Grade or (MIG). Such ratings recognize the
  differences between short-term credit risk and long-term risk. Factors
  affecting the liquidity of the borrower and short-term cyclical elements are
  critical in short-term ratings, while other factors of major importance in
  bond risk, long-term secular trends for example, may be less important over
  the short run. A short-term rating may also be assigned on an issue having a
  demand feature-variable rate demand obligation. Such ratings will be
  designated as VMIG, SG or, if the demand feature is not rated, as NR.
 
    Moody's short-term ratings are designated Moody's Investment Grade as MIG 1
  or VMIG 1 through MIG 4 or VMIG 4. As the name implies, when Moody's assigns a
  MIG or VMIG rating, all categories define an investment grade situation.

    MIG 1/VMIG 1. This designation denotes best quality. There is present strong
  protection by established cash flows, superior liquidity support or
  demonstrated broad-based access to the market for refinancing.
 
    MIG 2/VMIG 2. This designation denotes high quality. Margins of protection
  are ample although not so large as in the preceding group.
 
    MIG 3/VMIG 3. This designation denotes favorable quality. All security
  elements are accounted for but there is lacking the undeniable strength of the
  preceding grades. Liquidity and cash flow protection may be narrow and market
  access for refinancing is likely to be less well established.
 
    MIG 4/VMIG 4. This designation denotes adequate quality. Protection commonly
  regarded as required of an investment security is present and although not
  distinctly or predominantly speculative, there is specific risk.
 
    SG. This designation denotes speculative quality. Debt instruments in this
  category lack margins of protection.
 
  3. TAX-EXEMPT COMMERCIAL PAPER
 
   
    Moody's short-term debt ratings are opinions of the ability of issuers to
  repay punctually promissory obligations not having an original maturity in
  excess of nine months. Moody's makes no representation that such obligations
  are exempt form registration under the Securities Act of 1933, nor does it
  represent that any specific note is a valid obligation of a rated issuer or
  issued in conformity with any applicable law.
    
 
   
    Moody's employs the following three designations, all judged to be
  investment grade, to indicate the relative repayment ability of rated issuers:
    
 
   
       Issuers rated Prime-1 (for related supporting institutions) have a
     superior capacity for repayment of short-term promissory obligations.
     Prime-1 repayment capacity will normally be evidenced by the following
     characteristics:
    
 
   
      - Leading market positions in well established industries.
    
   
      - High rates of return on funds employed.
    
   
      - Conservative capitalization structures with moderate reliance on debt
        and ample asset protection.
    
   
      - Broad margins in earning coverage of fixed financial charges and high
        internal cash generation.
    
   
      - Well established access to a range of financial markets and assured
        sources of alternate liquidity.
    
 
   
       Issuers rated Prime-2 (or related supporting institutions) have a strong
     capacity for repayment of short-term promissory obligations. This will
     normally be evidenced by many of the characteristics cited above but to a
     lesser degree. Earnings trends and coverage ratios, while sound, will be
     more subject to variation. Capitalization characteristics, while still
     appropriate, may be more affected by external conditions. Ample alternate
     liquidity is maintained.
    
 
   
       Issuers rated Prime-3 (or related supported institutions) have an
     acceptable capacity for repayment of short-term promissory obligations. The
     effects of industry characteristics and market composition may be more
     pronounced. Variability in earnings and profitability may result in changes
     in the level of debt protection measurements and the requirement for
     relatively high financial leverage. Adequate alternate liquidity is
     maintained.
    
 
   
    Issuers rated Not Prime do not fall within any of the Prime rating
  categories.

  Each of the trustees holds the same position with each of the funds in the
Fund Complex. As of December 31, 1996, there were 51 funds in the Fund Complex.
Each trustee who is not an affiliated person of VKAC, the Advisers, the
Distributor, ACCESS or Morgan Stanley (each a "Non-Affiliated Trustee") is
compensated by an annual retainer and meeting fees for services to the funds in
the Fund Complex. Each fund in the Fund Complex provides a deferred compensation
plan to its Non-Affiliated Trustees that allows trustees to defer receipt of
their compensation and earn a return on such deferred amounts based upon the
return of the common shares of the funds in the Fund Complex as more fully
described below. Each fund in the Fund Complex also provides a retirement plan
to its Non-Affiliated Trustees that provides Non-Affiliated Trustees with
compensation after retirement, provided that certain eligibility requirements
are met as more fully described below.
    
 
   
  The compensation of each Non-Affiliated Trustee from each fund in the Fund
Complex advised by Advisory Corp. (each a "VK Fund" and collectively the "VK
Funds") includes an annual retainer in an amount equal to $2,500 per calendar
year, due in four quarterly installments on the first business day of each
calendar quarter. Each Non-Affiliated Trustee receives a per meeting fee from
each VK Fund in the amount of $125 per regular quarterly meeting attended by the
Non-Affiliated Trustee, due on the date of such meeting, plus reasonable
expenses incurred by the Non-Affiliated Trustee in connection with his or her
services as a trustee. Each Non-Affiliated Trustee receives a per meeting fee
from each VK Fund in the amount of $125 per special meeting attended by the
Non-Affiliated Trustee, due on the date of such meeting, plus reasonable
expenses incurred by the Non-Affiliated Trustee in connection with his or her
services as a trustee, provided that no compensation will be paid in connection
with certain telephonic special meetings.
    
 
   
  The compensation of each Non-Affiliated Trustee from the funds in the Fund
Complex advised by Asset Management (each an "AC Fund" or collectively the "AC
Funds") includes an annual retainer in an amount equal to $35,000 per calendar
year, due in four quarterly installments on the first business day of each
calendar quarter. The AC Funds pay each Non-Affiliated Trustee a per meeting fee
in the amount of $2,000 per regular quarterly meeting attended by the
Non-Affiliated Trustee, due on the date of such meeting, plus reasonable
expenses incurred by the Non-Affiliated Trustee in connection with his or her
services as a trustee. Payment of the annual retainer and the regular meeting
fee is allocated among the AC Funds (i) 50% on the basis of the relative net
assets of each AC Fund to the aggregate net assets of all the AC Funds and (ii)
50% equally to each AC Fund, in each case as of the last business day of the
preceding calendar quarter. Each AC Fund which is the subject of a special
meeting of the trustees generally pays each Non-Affiliated Trustee a per meeting
fee in the amount of $125 per special meeting attended by the Non-Affiliated
Trustee, due on the date of such meeting, plus reasonable expenses incurred by
the Non-Affiliated Trustee in connection with his or her services as a trustee,
provided that no compensation will be paid in connection with certain telephonic
special meetings.
    
 
   
  The trustees approved an aggregate compensation cap with respect to funds in
the Fund Complex of $84,000 per Non-Affiliated Trustee per year (excluding any
retirement benefits) for the period July 22, 1995 through December 31, 1996,
subject to the net assets and the number of funds in the Fund Complex as of July
21, 1995 and certain other exceptions. For the calendar year ended December 31,
1996, certain trustees received aggregate compensation from the funds in the
Fund Complex over $84,000 due to compensation received but not subject to the
cap, including compensation from new funds added to the Fund Complex after July
22, 1995 and certain special meetings in 1996. In addition, each of Advisory
Corp. or Asset Management, as the case may be, agreed to reimburse each fund in
the Fund Complex through December 31, 1996 for any increase in the aggregate
trustee's compensation over the aggregate compensation paid by such fund in its
1994 fiscal year, provided that if a fund did not exist for the entire 1994
fiscal year appropriate adjustments will be made.
    
 
   
  Each Non-Affiliated Trustee generally can elect to defer receipt of all or a
portion of the compensation earned by such Non-Affiliated Trustee until
retirement. Amounts deferred are retained by the Fund and earn a rate of return
determined by reference to the return on the common shares of such Fund or other
funds in the Fund Complex as selected by the respective Non-Affiliated Trustee,
with the same economic effect as if such Non-Affiliated Trustee had invested in
one or more funds in the Fund Complex. To the extent permitted by the 1940 Act,
the Fund may invest in securities of those funds selected by the Non-Affiliated
Trustees in
    
 
                                      B-47

order to match the deferred compensation obligation. The deferred compensation
plan is not funded and obligations thereunder represent general unsecured claims
against the general assets of the Fund.
    
 
   
  Each fund in the Fund Complex has adopted a retirement plan. Under the Fund's
retirement plan, a Non-Affiliated Trustee who is receiving trustee's
compensation from the Fund prior to such Non-Affiliated Trustee's retirement,
has at least 10 years of service (including years of service prior to adoption
of the retirement plan) and retires at or after attaining the age of 60, is
eligible to receive a retirement benefit equal to $2,500 per year for each of
the ten years following such trustee's retirement from the Fund. Trustees
retiring prior to the age of 60 or with fewer than 10 years but more than 5
years of service may receive reduced retirement benefits from the Fund. Each
trustee has served as a member of the Board of Trustees since he or she was
first appointed or elected in the year set forth below. The retirement plan
contains a Fund Complex retirement benefit cap of $60,000 per year. Asset
Management has reimbursed each AC Fund for the expenses related to the
retirement plan through December 31, 1996.
    
 
   
  Additional information regarding compensation and benefits for trustees is set
forth below. As indicated in the notes accompanying the table, the amounts
relate to either the Trust's most recently completed fiscal year or the Fund
Complex' most recently completed calendar year ended December 31, 1996.

*  Currently a member of the Board of Trustees. Mr. Phillip B. Rooney also is a
   current member of the Board of Trustees but is not included in the
   compensation table because he did not serve on the Board of Trustees or
   receive any compensation from the Trust prior to April 14, 1997. Messrs.
   McDonnell and Powell, also trustees of the Trust during all or a portion of
   the Trust's last fiscal year, are not included in the compensation table
   because they are affiliated persons of the Advisers and are not eligible for
   compensation or retirement benefits from the Trust.
    
 
   
(1) Persons not designated by an asterisk are not currently members of the Board
    of Trustees, but were members of the Board of Trustees during the Trust's
    most recently completed fiscal year. Messrs. Gaughan and Rees retired from
    the Board of Trustees on January 26, 1996 and January 29, 1996,
    respectively. Mr. Sheehan was removed from the Board of Trustees effective
    January 29, 1996. Messrs. Hilsman, Miller and Woodside retired from the
    Board of Trustees on December 31, 1996.
    
 
   
(2) The amounts shown in this column represent the aggregate compensation before
    deferral from all eight series of the Trust, including the Fund, with
    respect to the Trust's fiscal year ended December 31, 1996.

    The detail of aggregate compensation before deferral for each series,
    including the Fund, are shown in Table A below. Certain trustees deferred
    compensation from the Trust during the fiscal year ended December 31, 1996;
    the aggregate compensation deferred from all eight series of the Trust,
    including the Fund, is as follows: Mr. Branagan, $5,750; Mr. Gaughan,
    $3,750; Ms. Heagy, $15,000; Mr. Kennedy, $9,500; Mr. Miller, $20,000; Mr.
    Nelson, $20,000; Mr. Robinson, $18,000; and Mr. Whalen, $19,625. The details
    of amounts deferred for each series, including the Fund, are shown in Table
    B below. Amounts deferred are retained by the respective fund and earn a
    rate of return determined by reference to either the return on the common
    shares of such fund or other funds in the Fund Complex as selected by the
    respective Non-Affiliated Trustee, with the same economic effect as if such
    Non-Affiliated Trustee had invested in one or more funds in the Fund
    Complex. To the extent permitted by the 1940 Act, each fund may invest in
    securities of those funds selected by the Non-Affiliated Trustees in order
    to match the deferred compensation obligation. The cumulative deferred
    compensation (including interest) accrued with respect to each trustee from
    all eight series of the Trust, including the Fund, as of the Trust's fiscal
    year ended December 31, 1996 is as follows: Mr. Branagan, $5,678; Mr.
    Gaughan, $20,094; Ms. Heagy, $20,472; Mr. Kennedy, $47,294; Mr. Miller,
    $55,827; Mr. Nelson, $57,771; Mr. Robinson, $54,847; and Mr. Whalen,
    $49,269. The details of cumulative deferred compensation (including
    interest) for each series, including the Fund, are shown in Table C below.
    The deferred compensation plan is described above the Compensation Table.
    
 
   
(3) The amounts shown in this column represent the retirement benefits accrued
    by all eight series of the Trust, including the Fund, with respect to the
    Trust's fiscal year ended December 31, 1996. The details of retirement
    benefits accrued for each series, including the Fund, are shown in Table D
    below. The retirement plan is described above the Compensation Table.
    
 
   
(4) This is the estimated maximum annual benefits payable by the Trust in each
    year of the 10-year period commencing in the year of such trustee's
    retirement from the Trust. The estimated maximum annual benefit, except for
    trustees who have retired or are near retirement, is based upon $2,500 per
    series assuming: the trustee has 10 or more years of service on the Board of
    Trustees (including years of service prior to the adoption of the retirement
    plan) and retires at or after attaining the age of 60. Trustees retiring
    prior to the age of 60 or with fewer than 10 years of service for a series
    of the Trust may receive reduced retirement benefits from such series. The
    actual annual benefit may be less if the trustee is subject to the Fund
    Complex retirement benefit cap or if the trustee is not fully vested at the
    time of retirement. Each Non-Affiliated Trustee of the Board of Trustees has
    served as a member of the Board of Trustees since he or she was first
    appointed or elected in the year set forth in Table E below.
    
 
   
(5) The amounts shown in this column represent the aggregate compensation paid
    by all 51 of the investment companies in the Fund Complex as of December 31,
    1996 before deferral by the trustees under the deferred compensation plan.
    Certain trustees deferred all or a portion of their aggregate compensation
    from the Fund Complex during the calendar year ended December 31, 1996. The
    deferred compensation earns a rate of return determined by reference to the
    return on the shares of the funds in the Fund Complex as selected by the
    respective Non-Affiliated Trustee, with the same economic effect as if such
    Non-Affiliated Trustee had invested in one or more funds in the Fund
    Complex. To the extent permitted by the 1940 Act, the Fund may invest in
    securities of those investment companies selected by the Non-Affiliated
    Trustees in order to match the deferred compensation obligation. The
    trustees' Fund Complex compensation cap covered the period July 22, 1995
    through December 31, 1996. For the calendar year ended December 31, 1996,
    certain trustees received compensation over $84,000 in the aggregate due to
    compensation received but not subject to the cap, including compensation
    from new funds added to the Fund Complex after July 22, 1995 and certain
    special meetings in 1996. The Advisers and their affiliates also serve as
    investment adviser for other investment companies; however, with the
    exception of Messrs. McDonnell, Powell and Whalen, the trustees were not
    trustees of such investment companies. Combining the Fund Complex with other
    investment companies advised by the Advisers and their affiliates, Mr.
    Whalen received Total Compensation of $243,375 during the calendar year
    ended December 31, 1996.
    
 
   
  As of April 4, 1997, the trustees and officers of the Fund as a group owned
less than 1% of the shares of the Fund.

                     INVESTMENT ADVISORY AND OTHER SERVICES
 
INVESTMENT ADVISORY AGREEMENT
 
   
  The Adviser is the Fund's investment adviser. The Adviser was incorporated as
a Delaware corporation in 1982 (and through December 31, 1987 transacted
business under the name of American Portfolio Advisory Service Inc.).
    
 
   
  The Adviser is a wholly-owned subsidiary of Van Kampen American Capital, Inc.
("VKAC"), which is a wholly-owned subsidiary of VK/AC Holding, Inc. VK/AC
Holding Inc. is a wholly-owned subsidiary of MSAM Holdings II, Inc. which, in
turn, is a wholly-owned subsidiary of Morgan Stanley Group Inc. The principal
office of the Fund, the Adviser, the Distributor and VKAC is located at One
Parkview Plaza, Oakbrook Terrace, Illinois 60181.
    
 
   
  Morgan Stanley Group Inc. and various of its directly or indirectly owned
subsidiaries, including Morgan Stanley & Co. Incorporated, a registered
broker-dealer and investment adviser, and Morgan Stanley International, are
engaged in a wide range of financial services. Their principal businesses
include securities underwriting, distribution and trading; merger, acquisition,
restructuring and other corporate finance advisory activities; merchant banking;
stock brokerage and research services; asset management; trading of futures,
options, foreign exchange, commodities and swaps (involving foreign exchange,
commodities, indices and interest rates); real estate advice, financing and
investing; and global custody, securities clearance services and securities
lending.
    
 
   
  On February 5, 1997, Morgan Stanley Group Inc. and Dean Witter, Discover & Co.
announced that they had entered into an Agreement and Plan of Merger to form
Morgan Stanley, Dean Witter, Discover & Co. Subject to certain conditions being
met, it is currently anticipated that the transaction will close in mid-1997.
Thereafter, Van Kampen American Capital Asset Management, Inc. will be an
indirect subsidiary of Morgan Stanley, Dean Witter, Discover & Co.
    
 
   
  Dean Witter, Discover & Co. is a financial services company with three major
businesses; full service brokerage, credit services and asset management.
    
 
   
  The investment advisory agreement between the Adviser and the Fund provides
that the Adviser will supply investment research and portfolio management,
including the selection of securities for the Fund to purchase. The Adviser also
administers the business affairs of the Fund, furnishes offices, necessary
facilities and equipment, provides administrative services, and permits its
officers and employees to serve without compensation as officers of the Fund and
trustees of the Trust if duly elected to such positions.
    
 
  The agreement provides that the Adviser shall not be liable for any error of
judgment or of law, or for any loss suffered by the Fund in connection with the
matters to which the agreement relates, except a loss resulting from willful
misfeasance, bad faith, or gross negligence on the part of the Adviser in the
performance of its obligations and duties, or by reason of its reckless
disregard of its obligations and duties under the agreement.
 
                                      B-52
<PAGE>   871
 
  The Adviser's activities are subject to the review and supervision of the
Board of Trustees of the Trust, of which the Fund is a series, to whom the
Adviser renders periodic reports of the Fund's investment activities.
 
  The agreement will continue in effect from year to year if specifically
approved by the Trustees of the Trust, of which the Fund is a separate series
(or by the Fund's shareholders), and by the disinterested trustees in compliance
with the requirements of the 1940 Act. The agreement may be terminated without
penalty upon 60 days' written notice by either party thereto and will
automatically terminate in the event of assignment.
 
  The investment advisory agreement specifies that the Adviser will reimburse
the Fund for annual expenses of the Fund which exceed the most stringent limit
prescribed by any state in which the Fund's shares are offered for sale.
Currently, the most stringent limit in any state would require such
reimbursement to the extent that aggregate operating expenses of the Fund
(excluding interest, taxes and other expenses which may be excludable under
applicable state law) exceed in any fiscal year 2 1/2% of the average annual net
assets of the Fund up to $30 million, 2% of the average annual net assets of the
Fund of the next $70 million, and 1 1/2% of the remaining average annual net
assets of the Fund. In addition to making any required reimbursements, the
Adviser may in its discretion, but is not obligated to, waive all or any portion
of its fee or assume all or any portion of the expenses of the Fund.
 
   
  For the years ended December 31, 1996, 1995 and 1994, the Fund paid advisory
expenses of $0, $0 and $0, respectively.
    
 
OTHER AGREEMENTS
 
   
  ACCOUNTING SERVICES AGREEMENT.  The Fund has also entered into an accounting
services agreement pursuant to which the Adviser provides accounting services
supplementary to those provided by the Custodian. Such services are expected to
enable the Fund to more closely monitor and maintain its accounts and records.
The Fund shares together with the other Van Kampen American Capital mutual funds
in the cost to provide such services, with 25% of such costs shared
proportionately based on the respective number of classes of securities issued
per fund and the remaining 75% of such cost based proportionally on their
respective net assets.
    
 
   
  For each of the years ended December 31, 1996, 1995 and 1994, the Adviser
waived its cost of providing accounting services to the Fund.
    
 
   
  LEGAL SERVICES AGREEMENT.  The Fund and each of the other Van Kampen American
Capital funds advised by the Adviser and distributed by the Distributor have
entered into Legal Services Agreements pursuant to which Van Kampen American
Capital provides legal services, including without limitation: accurate
maintenance of the funds' minute books and records, preparation and oversight of
the funds' regulatory reports, and other information provided to shareholders,
as well as responding to day-to-day legal issues on behalf of the funds. Payment
by the Fund for such services is made on a cost basis for the salary and salary
related benefits, including but not limited to bonuses, group insurances and
other regular wages for the employment of personnel, as well as overhead and the
expenses related to the office space and the equipment necessary to render the
legal services. Other funds distributed by the Distributor also receive legal
services from Van Kampen American Capital. Of the total costs for legal services
provided to funds distributed by the Distributor, one half of such costs are
allocated equally to each fund and the remaining one half of such costs are
allocated to specific funds based on monthly time records.
    
 
   
  For each of the years ended December 31, 1996, 1995 and 1994, Van Kampen
American Capital waived its cost of providing legal services to the Fund.
    
 
   
                     CUSTODIAN AND INDEPENDENT ACCOUNTANTS
    
 
  State Street Bank and Trust Company, 225 Franklin Street, P.O. Box 1713,
Boston, MA 02105-1713, is the custodian of the Fund and has custody of all
securities and cash of the Fund. The custodian, among other things, attends to
the collection of principal and income, and payment for and collection of
proceeds of securities bought and sold by the Fund.
 
                                      B-53
<PAGE>   872
 
   
  The independent accountants for the Fund are KPMG Peat Marwick LLP, Chicago,
Illinois. The selection of independent accountants will be subject to
ratification by the shareholders of the Fund at any annual meeting of
shareholders.
    
 
                PORTFOLIO TRANSACTIONS AND BROKERAGE ALLOCATION
 
  The Adviser will place orders for portfolio transactions for the Fund with
broker-dealer firms giving consideration to the quality, quantity and nature of
each firm's professional services. These services include execution, clearance
procedures, wire service quotations and statistical and other research
information provided to the Fund, or the Adviser, including quotations necessary
to determine the value of the Fund's net assets. Any research benefits derived
are available for all clients of the Adviser. Since statistical and other
research information is only supplementary to the research efforts of the
Adviser to the Fund and still must be analyzed and reviewed by its staff, the
receipt of research information is not expected to materially reduce its
expenses. In selecting among the firms believed to meet the criteria for
handling a particular transaction, the Fund's Adviser may take into
consideration that certain firms have sold or are selling shares of the Fund and
that certain firms provide market, statistical or other research information to
the Fund and the Adviser, and may select firms that are affiliated with the
Fund, the Adviser, or its distributor and other principal underwriters.
 
  If it is believed to be in the best interests of the Fund, the Adviser may
place portfolio transactions with brokers who provide the types of research
service described above, even if it means the Fund will have to pay a higher
commission (or, if the broker's profit is part of the cost of the security, will
have to pay a higher price for the security), than would be the case if no
weight were given to the broker's furnishing of those research services. This
will be done, however, only if, in the opinion of the Fund's Adviser, the amount
of additional commission or increased cost is reasonable in relation to the
value of the such services.
 
  In selecting among the firms believed to meet the criteria for handling a
particular transaction, the Adviser may take into consideration that certain
firms (i) provide market, statistical or other research information such as that
set forth to the Fund and the Adviser, (ii) have sold or are selling shares of
the Fund and (iii) may select firms that are affiliated with the Fund, its
investment adviser or its distributor or other principal underwriters. If
purchases or sales of securities of the Fund and of one or more other investment
companies or clients supervised by the Adviser are considered at or about the
same time, transactions in such securities will be allocated among the several
investment companies and clients in a manner deemed equitable to all by the
Adviser, taking into account the respective sizes of the Fund and other
investment companies and clients and the amount of securities to be purchased or
sold. Although it is possible that in some cases this procedure could have a
detrimental effect on the price or volume of the security as far as the Fund is
concerned, it is also possible that the ability to participate in volume
transactions and to negotiate lower brokerage commissions will be beneficial to
the Fund.
 
  While the Adviser will be primarily responsible for the placement of the
Fund's business, the policies and practices in this regard must be consistent
with the foregoing and will at all times be subject to review by the trustees of
the Trust, of which the Fund is a separate series.
 
  The trustees have adopted certain policies incorporating the standards of Rule
17e-1 issued by the SEC under the 1940 Act which requires that the commissions
paid to the Distributor and other affiliates of the Fund must be reasonable and
fair compared to the commissions, fees or other remuneration received or to be
received by other brokers in connection with comparable transactions involving
similar securities during a comparable period of time. The rule and procedures
also contain review requirements and require the Adviser to furnish reports to
the trustees and to maintain records in connection with such reviews. After
consideration of all factors deemed relevant, the Trustees will consider from
time to time whether the advisory fee for the Fund will be reduced by all or a
portion of the brokerage commission given to affiliated brokers.
 
  State securities laws may differ from the interpretations of federal law
expressed herein, and banks and financial institutions may be required to
register as dealers pursuant to state law.

                             TAX STATUS OF THE FUND
 
   
  The Trust and any of its series, including the Fund, will be treated as
separate corporations for federal income tax purposes. The Fund intends to
qualify each year and to elect to be treated as a regulated investment company
under the Code. If the Fund so qualifies and distributes each year to its
shareholders at least 90% of its net investment income (including tax-exempt
interest, taxable income and net short-term capital gain, but not net capital
gains, which are the excess of long-term capital gains over net short-term
capital losses) in each year, it will not be required to pay federal income
taxes on any income distributed to shareholders. The Fund intends to distribute
at least the minimum amount of net investment income necessary to satisfy the
90% distribution requirement. The Fund will not be subject to federal income tax
on any net capital gains distributed to shareholders.
    
 
  The table below illustrates approximate equivalent taxable and tax-free yields
at the 1994 federal and New York State individual income tax rates in effect on
the date of this Statement of Additional Information, including the 36% and
39.6% rates enacted in August 1993 as part of the Revenue Reconciliation Act of
1993.
 
  The table shows, for example, that a couple with a taxable income of $90,000,
or a single individual with a taxable income of $55,000, whose investments earn
a 6% tax-free yield, would have to earn approximately a 8.9% taxable yield at
current federal and state income tax rates to receive the same benefit.

                                THE DISTRIBUTOR
 
   
  The Distributor offers one of the industry's broadest lines of investments --
encompassing mutual funds, closed-end funds and unit investment trusts -- and is
currently the nation's 5th largest broker-sold mutual fund group according to
Strategic Insight, July 1995. VKAC manages or supervises more than $57 billion
in mutual funds, closed-end funds and unit investment trusts -- assets which
have been entrusted to VKAC in more than 2 million investor accounts. VKAC has
one of the largest research teams (outside of the rating agencies) in the
country, with more than 80 analysts devoted to various specializations. Each of
our high yield analysts, based either in San Francisco, Chicago, Houston or
Boston, has the responsibility to cover a specific region of the country. This
regional focus enables each high yield analyst to provide more specialized
coverage of the market and alert the portfolio manager to issues of local
importance.
    
 
   
  Shares of the Fund are offered on a continuous basis through the Distributor,
One Parkview Plaza, Oakbrook Terrace, IL 60181. The Distributor is a wholly
owned subsidiary of MSAM Holdings II, Inc. which, in turn, is a wholly-owned
subsidiary of Morgan Stanley Group Inc. The principal office of the Fund, the
Adviser, the Distributor and VKAC is located at One Parkview Plaza, Oakbrook
Terrace, Illinois 60181.

  Morgan Stanley Group Inc. and various of its directly or indirectly owned
subsidiaries, including Morgan Stanley & Co. Incorporated, a registered
broker-dealer and investment adviser, and Morgan Stanley International, are
engaged in a wide range of financial services. Their principal businesses
include securities underwriting, distribution and trading; merger, acquisition,
restructuring and other corporate finance advisory activities; merchant banking;
stock brokerage and research services; asset management; trading of futures,
options, foreign exchange, commodities and swaps (involving foreign exchange,
commodities, indices and interest rates); real estate advice, financing and
investing; and global custody, securities clearance services and securities
lending.
    
 
   
  On February 5, 1997, Morgan Stanley Group Inc. and Dean Witter, Discover & Co.
announced that they had entered into an Agreement and Plan of Merger to form
Morgan Stanley, Dean Witter, Discover & Co. Subject to certain conditions being
met, it is currently anticipated that the transaction will close in mid-1997.
Thereafter, Van Kampen American Capital Asset Management, Inc. will be an
indirect subsidiary of Morgan Stanley, Dean Witter, Discover & Co.
    
 
   
  Dean Witter, Discover & Co. is a financial services company with three major
businesses; full service brokerage, credit services and asset management.
    
 
   
  Pursuant to a distribution agreement, the Distributor will purchase shares of
the Fund for resale to the public, either directly or through securities
dealers, and is obligated to purchase only those shares for which it has
received purchase orders. A discussion of how to purchase and redeem the Fund's
shares and how the Fund's shares are priced is contained in the Prospectus.
    
 
   
                         DISTRIBUTION AND SERVICE PLANS
    
 
   
  The Fund has adopted a distribution plan (the "Distribution Plan") with
respect to each class of its shares pursuant to Rule 12b-1 under the 1940 Act.
The Fund also has adopted a service plan (the "Service Plan") with respect to
each class of shares. The Distribution Plan and Service Plan sometimes are
referred to herein collectively as the "Plans". The Plans provide that the Fund
may spend a portion of the Fund's average daily net assets attributable to each
class of shares in connection with distribution of the respective class of
shares and in connection with the provision of ongoing services to shareholders
of such class, respectively. The Plans are being implemented through an
agreement (the "Distribution and Service Agreement") with the Distributor and
sub-agreements between the Distributor and members of the NASD who are acting as
securities dealers and NASD members or eligible non-members who are acting as
brokers or agents and similar agreements between the Fund and financial
intermediaries who are acting as brokers (collectively, "Selling Agreements")
that may provide for their customers or clients certain services or assistance,
which may include, but not be limited to, processing purchase and redemption
transactions, establishing and maintaining shareholder accounts regarding the
Fund, and such other services as may be agreed to from time to time and as may
be permitted by applicable statute, rule or regulation. Brokers, dealers and
financial intermediaries that have entered into sub-agreements with the
Distributor and sell shares of the Fund are referred to herein as "financial
intermediaries."
    
 
  The Distributor must submit quarterly reports to the Board of Trustees of the
Trust, of which the Fund is a series, setting forth separately by class of
shares all amounts paid under the Plans and the purposes for which such
expenditures were made, together with such other information as from time to
time is reasonably requested by the Trustees. The Plans provide that they will
continue in full force and effect from year to year so long as such continuance
is specifically approved by a vote of the Trustees, and also by a vote of the
disinterested Trustees, cast in person at a meeting called for the purpose of
voting on the Plans. Each of the Plans may not be amended to increase materially
the amount to be spent for the services described therein with respect to either
class of shares without approval by a vote of a majority of the outstanding
voting shares of such class, and all material amendments to either of the Plans
must be approved by the Trustees and also by the disinterested Trustees. Each of
the Plans may be terminated with respect to either class of shares at any time
by a vote of a majority of the disinterested Trustees or by a vote of a majority
of the outstanding voting shares of such class.
 
   
  For the fiscal year ended December 31, 1996, the Fund's aggregate expenses
under the Plans for Class A shares were $10,655 or 0.16% of the Class A shares'
average net assets. Such expenses were paid to reimburse
    
 
                                      B-56
<PAGE>   875
 
   
the Distributor for payments made to financial intermediaries for servicing Fund
shareholders and for administering the Class A Plan. For the fiscal year ended
December 31, 1996, the Fund's aggregate expenses under the Plans for Class B
shares were $91,848 or 0.91% of the Class B shares' average net assets. Such
expenses were paid to reimburse the Distributor for the following payments:
$75,324 for commissions and transaction fees paid to financial intermediaries in
respect of sales of Class B shares of the Fund and $16,524 for fees paid to
financial intermediaries for servicing Class B shareholders and administering
the Plans. For the fiscal year ended December 31, 1996, the Fund's aggregate
expenses under the Plans for Class C shares were $3,423 or 0.92% of the Class C
shares' average net assets. Such expenses were paid to reimburse the Distributor
for the following payments: $0 for commissions and transaction fees paid to
financial intermediaries in respect of sales of Class C shares of the Fund and
$3,423 for fees paid to financial intermediaries for servicing Class C
shareholders and administering the Plans.
    
 
                                 LEGAL COUNSEL
 
   
  Counsel to the Fund is Skadden, Arps, Slate, Meagher & Flom (Illinois).
    
 
                            PERFORMANCE INFORMATION
 
  From time to time marketing materials may provide a portfolio manager update,
an adviser update or discuss general economic conditions and outlooks. The
Fund's marketing materials may also show the Fund's asset class diversification,
top five sectors, ten largest holdings and other Fund asset structures, such as
duration, maturity, coupon, NAV, rating breakdown, AMT exposure and number of
issues in the portfolio. Materials may also mention how Van Kampen American
Capital believes the Fund compares relative to other Van Kampen American Capital
funds. Materials may also discuss the Dalbar Financial Services study from 1984
to 1994 which studied investor cash flow into and out of all types of mutual
funds. The ten year study found that investors who bought mutual fund shares and
held such shares outperformed investors who bought and sold. The Dalbar study
conclusions were consistent regardless of if shareholders purchased their funds
in direct or sales force distribution channels. The study showed that investors
working with a professional representative have tended over time to earn higher
returns than those who invested directly. The Fund will also be marketed on the
Internet.
 
  The Fund's yield quotation is determined on a monthly basis with respect to
the immediately preceding 30 day period, and yield is computed by dividing the
Fund's net investment income per share of a given class earned during such
period by the Fund's maximum offering price (including, with respect to the
Class A Shares, the maximum initial sales charge) per share of such class on the
last day of such period. The Fund's net investment income per share is
determined by taking the interest attributable to a given class of shares earned
by the Fund during the period, subtracting the expenses attributable to a given
class of shares accrued for the period (net of any reimbursements), and dividing
the result by the average daily number of the shares of each class outstanding
during the period that were entitled to receive dividends. The yield calculation
formula assumes net investment income is earned and reinvested at a constant
rate and annualized at the end of a six month period. Yield will be computed
separately for each class of shares. Class B Shares redeemed during the first
seven years after their issuance and Class C Shares redeemed during the first
year after their issuance may be subject to a contingent deferred sales charge
in a maximum amount equal to 4.00% and 1.00%, respectively, of the lesser of the
then current net asset value of the shares redeemed or their initial purchase
price from the Fund. Yield quotations do not reflect the imposition of a
contingent deferred sales charge, and if any such contingent deferred sales
charge imposed at the time of redemption were reflected, it would reduce the
performance quoted.
 
  Tax-equivalent yield demonstrates the taxable yield required to produce an
after-tax yield equivalent to that of the Fund's yield. The Fund's
tax-equivalent yield quotation for a 30 day period as described above is
computed by dividing that portion of the yield of the Fund (as computed above)
which is tax-exempt by a percentage equal to 100% minus a stated percentage
income tax rate and adding the result to that portion of the Fund's yield, if
any, that is not tax-exempt.
 
                                      B-57
<PAGE>   876
 
  The Fund calculates average compounded total return by determining the
redemption value (less any applicable contingent deferred sales charge) at the
end of specified periods (after adding back all dividends and other
distributions made during the period) of a $1,000 investment in a given class of
shares of the Fund (less the maximum sales charge, if any) at the beginning of
the period, annualizing the increase or decrease over the specified period with
respect to such initial investment and expressing the result as a percentage.
Average compounded total return will be computed separately for each class of
shares.
 
  Total return figures utilized by the Fund are based on historical performance
and are not intended to indicate future performance. Total return and net asset
value per share of a given class can be expected to fluctuate over time, and
accordingly upon redemption a shareholder's shares may be worth more or less
than their original cost.
 
  The Fund may, in supplemental sales literature, advertise non-standardized
total return figures representing the cumulative, non-annualized total return of
each class of shares of the Fund from a given date to a subsequent given date.
Cumulative non-standardized total return is calculated by measuring the value of
an initial investment in a given class of shares of the Fund at a given time,
deducting the maximum initial sales charge, if any, determining the value of all
subsequent reinvested distributions, and dividing the net change in the value of
the investment as of the end of the period by the amount of the initial
investment and expressing the result as a percentage. Non-standardized total
return will be calculated separately for each class of shares. Non-standardized
total return calculations do not reflect the imposition of a contingent deferred
sales charge, and if any such contingent deferred sales charge with respect to
the CDSC imposed at the time of redemption were reflected, it would reduce the
performance quoted.

                         NOTES TO FINANCIAL STATEMENTS
 
                               December 31, 1996
- --------------------------------------------------------------------------------
 
1. SIGNIFICANT ACCOUNTING POLICIES
 
Van Kampen American Capital New York Tax Free Income Fund (the "Fund") is
organized as a series of the Van Kampen American Capital Tax Free Trust, a
Delaware business trust, and is registered as a non-diversified open-end
management investment company under the Investment Company Act of 1940, as
amended. The Fund's investment objective is to provide investors with a high
level of current income exempt from federal, New York State and New York City
income taxes, consistent with preservation of capital. The Fund seeks to achieve
its investment objective by investing at least 80% of its assets in a portfolio
of New York municipal securities rated investment grade at the time of
investment. The Fund commenced investment operations on July 29, 1994.
 
    The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. The
preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.
 
A. SECURITY VALUATION--Investments are stated at value using market quotations
or, if such valuations are not available, estimates obtained from yield data
relating to instruments or securities with similar characteristics in accordance
with procedures established in good faith by the Board of Trustees. Short-term
securities with remaining maturities of 60 or less days are valued at amortized
cost.
 
B. SECURITY TRANSACTIONS--Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis. The
Fund may purchase and sell securities on a "when issued" or "delayed delivery"
basis, with settlement to occur at a later date. The value of the security so
purchased is subject to market fluctuations during this period. The Fund will
maintain, in a segregated account with its custodian, assets having an aggregate
value at least equal to the amount of the when issued or delayed delivery
purchase commitments until payment is made. At December 31, 1996, there were no
when issued or delayed delivery purchase commitments.
C. INVESTMENT INCOME--Interest income is recorded on an accrual basis. Bond
premium and original issue discount on securities purchased are amortized over
the expected life of each applicable security.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
                               December 31, 1996
- --------------------------------------------------------------------------------
 
D. ORGANIZATIONAL EXPENSES--The Fund will reimburse Van Kampen American Capital
Distributors, Inc. or its affiliates (collectively "VKAC") for costs incurred in
connection with the Fund's organization in the amount of $120,000. These costs
are being amortized on a straight line basis over the 60 month period ending
July 28, 1999. Van Kampen American Capital Investment Advisory Corp. (the
"Adviser") has agreed that in the event any of the initial shares of the Fund
originally purchased by VKAC are redeemed during the amortization period, the
Fund will be reimbursed for any unamortized organizational expenses in the same
proportion as the number of shares redeemed bears to the number of initial
shares held at the time of redemption.
 
E. FEDERAL INCOME TAXES--It is the Fund's policy to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income, if any, to its shareholders.
Therefore, no provision for federal income taxes is required.
 
    The Fund intends to utilize provisions of the Federal income tax laws which
allow it to carry a realized capital loss forward for eight years following the
year of the loss and offset such losses against any future realized capital
gains. At December 31, 1996, the Fund had an accumulated capital loss
carryforward for tax purposes of $130,324, which will expire on December 31,
2003.
 
F. DISTRIBUTION OF INCOME AND GAINS--The Fund declares daily and pays monthly
dividends from net investment income. Net realized gains, if any, are
distributed annually. Due to inherent differences in the recognition of certain
expenses under generally accepted accounting principles and federal income tax
purposes, the amount of distributable net investment income may differ between
book and federal income tax purposes for a particular period. These differences
are temporary in nature, but may result in book basis distribution in excess of
net investment income for certain periods.
 
2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES
Under the terms of the Fund's Investment Advisory Agreement, the Adviser will
provide investment advice and facilities to the Fund for an annual fee payable
monthly as follows:

- --------------------------------------------------------------------------------
 
    Certain legal expenses are paid to Skadden, Arps, Slate, Meagher & Flom,
counsel to the Fund, of which a trustee of the Fund is an affiliated person.
 
    For the year ended December 31, 1996, the Fund recognized expenses of
approximately $10,000 representing VKAC's cost of providing cash management and
legal services to the Fund. All of this cost has been assumed by VKAC.
 
    ACCESS Investor Services, Inc. ("ACCESS"), an affiliate of the Adviser,
serves as the shareholder servicing agent of the Fund. For the year ended
December 31, 1996, the Fund recognized expenses of approximately $7,500,
representing ACCESS' cost of providing transfer agency and shareholder services
plus a profit. All of this expense has been assumed by VKAC.
 
    Certain officers and trustees of the Fund are also officers and directors of
VKAC. The Fund does not compensate its officers or trustees who are officers of
VKAC.
 
    The Fund has implemented deferred compensation and retirement plans for its
trustees. Under the deferred compensation plan, trustees may elect to defer all
or a portion of their compensation to a later date. The retirement plan covers
those trustees who are not officers of VKAC.
 
    At December 31, 1996, VKAC owned 100 shares each of Classes A, B and C.
 
3. CAPITAL TRANSACTIONS
The Fund has outstanding three classes of shares of beneficial interest, Classes
A, B and C each with a par value of $.01 per share. There are an unlimited
number of shares of each class authorized.

ITEM 27. INDEMNIFICATION.
 
     Reference is made to Article 8, Section 8.4 of the Registrant's Agreement
and Declaration of Trust.
 
   
     Article 8, Section 8.4 of the Agreement and Declaration of Trust provides
that each officer and trustee of the Registrant shall be indemnified by the
Registrant against all liabilities incurred in connection with the defense or
disposition of any action, suit or other proceeding, whether civil or criminal,
in which the officer or trustee may be or may have been involved by reason of
being or having been an officer or trustee, except that such indemnity shall not
protect any such person against a liability to the Registrant or any shareholder
thereof to which such person would otherwise be subject by reason of (i) not
acting in good faith in the reasonable belief that such person's actions were
not in the best interests of the Trust, (ii) willful misfeasance, bad faith,
gross negligence or reckless disregard of the duties involved in the conduct of
his or her office (iii) for a criminal proceeding, not having a reasonable cause
to believe that such conduct was unlawful (collectively, "Disabling Conduct").
Absent a court determination that an officer or trustee seeking indemnification
was not liable on the merits or guilty of Disabling Conduct in the conduct of
his or her office, the decision by the Registrant to indemnify such person must
be based upon the reasonable determination of independent counsel or non-party
independent trustees, after review of the facts, that such officer or trustee is
not guilty of Disabling Conduct in the conduct of his or her office.
    
 
     The Registrant has purchased insurance on behalf of its officers and
trustees protecting such persons from liability arising from their activities as
officers or trustees of the Registrant. The insurance does not protect or
purport to protect such persons from liability to the Registrant or to its
shareholders to which such officers or trustee would otherwise be subject by
reason of willful misfeasance, bad faith, gross negligence or reckless disregard
of the duties involved in the conduct of their office.
 
     Conditional advancing of indemnification monies may be made if the trustee
or officer undertakes to repay the advance unless it is ultimately determined
that he or she is entitled to the indemnification and only if the following
conditions are met: (1) the trustee or officer provides security for the
undertaking; (2) the Registrant is insured against losses arising from lawful
advances; or (3) a majority of a quorum of the Registrant's disinterested,
non-party trustees, or an independent legal counsel in a written opinion, shall
determine, based upon a review of readily available facts, that a recipient of
the advance ultimately will be found entitled to indemnification.
 
     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 the trustee, officer, or controlling person of the
Registrant in the successful defense of any action, suit or proceeding) is
asserted 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
 
                                       C-6
<PAGE>   899
 
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.

                                      of

            Van Kampen American Capital Insured Tax Free Income Fund


The undersigned, being the Secretary of Van Kampen American Capital Tax Free
Trust, a Delaware business trust (the "Trust"), pursuant to the authority
conferred upon the Trustees of the Trust by Section 6.1 of the Trust's
Agreement and Declaration of Trust ("Declaration"), and by the affirmative vote
of a Majority of the Trustees does hereby establish and designate as a Series
of the Trust the Van Kampen American Capital Insured Tax Free Income Fund (the
"Fund") with the following rights, preferences and characteristics:

1.  Shares.  The beneficial interest in the Fund shall be divided into Shares
having a nominal or par value of $0.01 per Share, of which an unlimited number
may be issued, which Shares shall represent interests only in the Fund. The
Trustees shall have the authority from time to time to authorize separate
Series of Shares for the Trust as they deem necessary or desirable.

2.  Classes of Shares.  The Shares of the Fund shall be initially divided into
three classes--Class A, Class B and Class C.  The Trustees shall have the
authority from time to time to authorize additional Classes of Shares of the
Fund.

3.  Sales Charges.  Each Class A, Class B and Class C Share shall be subject to
such sales charges, if any, as may be established from time to time by the
Trustees in accordance with the Investment Company Act of 1940 (the "1940 Act")
and applicable rules and regulations of the National Association of Securities
Dealers, Inc., all as set forth in the Fund's prospectus.

4.  Conversion.  Each Class B Share and certain Class C Shares of the Fund 
shall be converted automatically, and without any action or choice on the
part of the Shareholder thereof, into Class A Shares of the Fund at such times
and pursuant to such terms, conditions and restrictions as may be established
by the Trustees and as set forth in the Fund's Prospectus.

5.  Allocation of Expenses Among Classes.  Expenses related solely to a
particular Class (including, without limitation, distribution expenses under an
administrative or service agreement, plan or other arrangement, however
designated) shall be borne by that Class and shall be appropriately reflected
(in a manner determined by the Trustees) in the net asset value, dividends,
distribution and liquidation rights of the Shares of that Class.

6.  Special Meetings.  A special meeting of Shareholders of a Class of the Fund
may be called with respect to the Rule 12b-1 distribution plan applicable to
such Class or with respect to any other proper purpose affecting only holders
of shares of such Class at any time by a Majority of the Trustees.

7.  Other Rights Governed by Declaration.  All other rights, preferences,
qualifications, limitations and restrictions with respect to Shares of any
Series of the Trust or with respect to any Class of Shares set forth in the
Declaration shall apply to Shares of the Fund unless otherwise specified in
this Certificate of Designation, in which case this Certificate of Designation
shall govern.

8.  Amendments, etc.  Subject to the provisions and limitations of Section 9.5
of the Declaration and applicable law, this Certificate of Designation may be
amended by an instrument signed in writing by a Majority of the Trustees (or by
any officer of the Trust pursuant to the vote of a Majority of the Trustees) or
when authorized to do so by the vote in accordance with the Declaration of the
holders of a majority of all the Shares of the Fund outstanding and entitled to
vote or, if such amendment affects the Shares of one or more but not all of the
Classes of the Fund, the holders of a majority of all the Shares of the
affected Classes outstanding and entitled to vote.

9.  Incorporation of Defined Terms.  All capitalized terms which are not
defined herein shall have the same meaning as ascribed to those terms in the
Declaration.

provided or authorized, shall have no authority to act for or represent the
Fund in any way or otherwise be deemed as agent of the Fund.

        (d) Non-Exclusive Agreement.  The services of the Adviser to the Fund
under this Agreement are not to be deemed exclusive, and the Adviser shall be
free to render similar services or other services to others so long as its
services hereunder are not impaired thereby.

     2. (a) Fee.  For the services and facilities described in Section 1, the
Fund will accrue daily and pay to the Adviser at the end of each calendar month
an investment management fee equal to a percentage of the average daily net
assets of the Fund as follows:


<TABLE>
<CAPTION>
                                           
                      AVERAGE DAILY        
                      NET ASSETS           % PER ANNUM
                      ------------------  ---------------
                      <S>                 <C>
                      First $500 million    0.525% 
                      Next $500 million     0.50% 
                      Next $500 million     0.475% 
                      Over $1.5 billion     0.45% 
</TABLE>


        (b) Expense Limitation.  The Adviser's compensation for any fiscal year
of the Fund shall be reduced by the amount, if any, by which the Fund's expense
for such fiscal year exceeds the most restrictive applicable expense
jurisdiction in which the Fund's shares are qualified for offer and sale, as
such limitations set forth in the most recent notice thereof furnished by the
Adviser to the Fund.  For purposes of this paragraph there shall be excluded
from computation of the Fund's expenses any amount borne directly or indirectly
by the Fund which is permitted to be excluded from the computation of such
limitation by such statute or regulatory authority.  If for any month expenses
of the Fund properly included in such calculation exceed 1/12 of the amount
permitted annually by the most restrictive applicable expense limitation, the
payment to the Adviser for that month shall be reduced, and, if necessary, the
Adviser shall make a refund payment to the Fund, so that the total net expense
for the month will not exceed 1/12 of such amount.  As of the end of the Fund's
fiscal year, however, the computations and payments shall be readjusted so that
the aggregate compensation payable to the Adviser for the year is equal to the
fee set forth in subsection (a) of this Section 2, diminished to the extent
necessary so that the expenses for the year do not exceed those permitted by
the applicable expense limitation.

        (c) Determination of Net Asset Value.  The net asset value of the Fund
shall be calculated as of the close of the New York Stock Exchange on each day
the Exchange is open for trading or such other time or times as the trustees
may determine in accordance with the provisions of applicable law and of the
Declaration of Trust and By-Laws of the Trust, and resolutions of the Board of
Trustees of the Fund as from time to time in force.  For the purpose of the
foregoing computations, on each such day when net asset value is not 
calculated, the net

<PAGE>   2
asset value of a share of beneficial interest of the Fund shall be deemed to be
the net asset value of such share as of the close of business of the last day on
which such calculation was made.

        (d)  Proration.  For the month and year in which this Agreement becomes
effective or terminates, there shall be an appropriate proration of the
Adviser's fee on the basis of the number of days that the Agreement is in
effect during such month and year, respectively.

     3. Expenses.  In addition to the fee of the Adviser, the Fund shall assume
and pay any expenses for services rendered by a custodian for the safekeeping
of the Fund's securities or other property, for keeping its books of account,
for any other charges of the custodian and for calculating the net asset value
of the Fund as provided above.  The Adviser shall not be required to pay, and
the Fund shall assume and pay, the charges and expenses of its operations,
including compensation of the trustees (other than those who are interested
persons of the Adviser and other than those who are interested persons of the
distributor of the Fund but not of the Adviser, if the distributor has agreed
to pay such compensation), charges and expenses of independent accountants, of
legal counsel and of any transfer or dividend disbursing agent, costs of
acquiring and disposing of portfolio securities, cost of listing shares of the
New York Stock Exchange or other exchange interest (if any) on obligations
incurred by the Fund, costs of share certificates, membership dues in the
Investment Company Institute or any similar organization, costs of reports and
notices to shareholders, costs of registering shares of the Fund under the
federal securities laws, miscellaneous expenses and all taxes and fees to
federal, state or other governmental agencies on account of the registration of
securities issued by the Fund, filing of corporate documents or otherwise.  The
Fund shall not pay or incur any obligation for any management or administrative
expenses for which the Fund intends to seek reimbursement from the Adviser
without first obtaining the written approval of the Adviser.  The Adviser shall
arrange, if desired by the Fund, for officers or employees of the Adviser to
serve, without compensation from the Fund, as trustees, officers or agents of
the Fund if duly elected or appointed to such positions and subject to their
individual consent and to any limitations imposed by law.

     4. Interested Persons.  Subject to applicable statutes and regulations, it
is understood that trustees, officers, shareholders and agents of the Fund are
or may be interested in the Adviser as directors, officers, shareholders,
agents or otherwise and that the directors, officers, shareholders and agents
of the Adviser may be interest in the Fund as trustees, officers, shareholders,
agents or otherwise.

     5. Liability.  The Adviser shall not be liable for any error of judgment
or of law, or for any loss suffered by the Fund in connection with the matters
to which this Agreement relates, except a loss resulting from willful
misfeasance, bad faith or gross negligence on the part of the Adviser in the
performance of its obligations and duties, or by reason of its reckless
disregard of its obligations and duties under this Agreement.

     6. (a)  Term.  This Agreement shall become effective on the date hereof
and shall remain in full force until the second anniversary of the date hereof
unless sooner terminated as hereinafter provided.  This Agreement shall
continue in force from year to year thereafter, but only as long as such
continuance is specifically approved as least annually in the manner required
by the Investment Company Act of 1940, as amended.

        (b)  Termination.   This Agreement shall automatically terminate in the
event of its assignment.  This Agreement may be terminated at any time without
the payment of any penalty by the Fund or by the Adviser on sixty (60) days
written notice to the other party.  The Fund may effect termination by action
of the Board of Trustees or by vote of a majority of the outstanding shares of
stock of the Fund, accompanied by appropriate notice.  This Agreement may be
terminated at any time without the payment of any penalty and without advance
notice by the Board of Trustees or by vote of a majority of the outstanding
shares of the Fund in the event that it shall have been established by a court
of competent jurisdiction that the Adviser or any officer or director of the
Adviser has taken any action which results in a breach of the covenants of the
Adviser set forth herein.

        (c)  Payment upon Termination.  Termination of this Agreement shall not
affect the right of the Adviser to receive payment on any unpaid balance of the
compensation described in Section 2 earned prior to such termination.

     7. Severability.  If any provision of this Agreement shall be held or made
invalid by a court decision, statute, rule or otherwise, the remainder shall
not thereby affected.

     8. Notices.  Any notice under this Agreement shall be in writing,
addressed and delivered or mailed, postage prepaid, to the other party at such
address as such other party may designate for the receipt of such notice.

     9. Disclaimer.  The Adviser acknowledges and agrees that, as provided by
Section 8.1 of the Declaration of Trust of the Trust, (i) this Agreement has
been executed by officers of the Trust in their capacity as officers, and not
individually, and (ii) the shareholders, trustees, officers, employees and
other agents of the Trust and the Fund shall not personally be bound by or
liable hereunder, nor shall resort be had to their private property for the
satisfaction of

<PAGE>   3
any obligation or claim hereunder and that any such resort may only be had upon
the assets and property of the Fund.

     10. Governing Law.  All questions concerning the validity, meaning and
effect of this Agreement shall be determined in accordance with the laws
(without giving effect to the conflict-of-law principles thereof) of the State

investment of funds shall be subject to all applicable restrictions of
applicable law and of the Declaration of Trust and By-Laws of the Trust, and
resolutions of the Board of Trustees of the Fund as may from time to time be in
force and delivered or made available to the Adviser.

        (b) Adviser's Acceptance of Employment.  The Adviser accepts such
employment and agrees during such period to render such services, to supply
investment research and portfolio management (including without limitation the
selection of securities for the Fund to purchase, hold or sell and the
selection of brokers through whom the Fund's portfolio transactions are
executed, in accordance with the policies adopted by the Fund and its Board of
Trustees), to administer the business affairs of the Fund, to furnish offices
and necessary facilities and equipment to the Fund, to provide administrative
services for the Fund, to render periodic reports to the Board of Trustees of
the Fund, and to permit any of its officers or employees to serve without
compensation as trustees or officers of the Fund if elected to such positions.

        (c) Independent Contractor.  The Adviser shall be deemed to be an
independent contractor under this Agreement and, unless otherwise expressly
provided or authorized, shall have no authority to act for or represent the
Fund in any way or otherwise be deemed as agent of the Fund.

        (d) Non-Exclusive Agreement.  The services of the Adviser to the Fund
under this Agreement are not to be deemed exclusive, and the Adviser shall be
free to render similar services or other services to others so long as its
services hereunder are not impaired thereby.

     2. (a) Fee.  For the services and facilities described in Section 1, the
Fund will accrue daily and pay to the Adviser at the end of each calendar month
an investment management fee equal to a percentage of the average daily net
assets of the Fund as follows:


<TABLE>
<CAPTION>
                                           
                      AVERAGE DAILY        
                      NET ASSETS            % PER ANNUM
                      ------------------  ---------------
                      <S>                 <C>
                      First $500 million    0.50% of 1.00%
                      Over $500 million     0.45% of 1.00%
</TABLE>


        (b) Expense Limitation.  The Adviser's compensation for any fiscal year
of the Fund shall be reduced by the amount, if any, by which the Fund's expense
for such fiscal year exceeds the most restrictive applicable expense
jurisdiction in which the Fund's shares are qualified for offer and sale, as
such limitations set forth in the most recent notice thereof furnished by the
Adviser to the Fund.  For purposes of this paragraph there shall be excluded
from computation of the Fund's expenses any amount borne directly or indirectly
by the Fund which is permitted to be excluded from the computation of such
limitation by such statute or regulatory authority.  If for any month expenses
of the Fund properly included in such calculation exceed 1/12 of the amount
permitted annually by the most restrictive applicable expense limitation, the
payment to the Adviser for that month shall be reduced, and, if necessary, the
Adviser shall make a refund payment to the Fund, so that the total net expense
for the month will not exceed 1/12 of such amount.  As of the end of the Fund's
fiscal year, however, the computations and payments shall be readjusted so that
the aggregate compensation payable to the Adviser for the year is equal to the
fee set forth in subsection (a) of this Section 2, diminished to the extent
necessary so that the expenses for the year do not exceed those permitted by
the applicable expense limitation.

        (c) Determination of Net Asset Value.  The net asset value of the Fund
shall be calculated as of the close of the New York Stock Exchange on each day
the Exchange is open for trading or such other time or times as the trustees
may determine in accordance with the provisions of applicable law and of the
Declaration of Trust and By-Laws of the Trust, and resolutions of the Board of
Trustees of the Fund as from time to time in force.  For the purpose of the
foregoing computations, on each such day when net asset value is not
calculated, the net asset value of a share of beneficial interest of the Fund
shall be deemed to be the net asset

<PAGE>   6
value of such share as of the close of business of the last day on which such
calculation was made.

        (d)  Proration.  For the month and year in which this Agreement becomes
effective or terminates, there shall be an appropriate proration of the
Adviser's fee on the basis of the number of days that the Agreement is in
effect during such month and year, respectively.

     3. Expenses.  In addition to the fee of the Adviser, the Fund shall assume
and pay any expenses for services rendered by a custodian for the safekeeping
of the Fund's securities or other property, for keeping its books of account,
for any other charges of the custodian and for calculating the net asset value
of the Fund as provided above.  The Adviser shall not be required to pay, and
the Fund shall assume and pay, the charges and expenses of its operations,
including compensation of the trustees (other than those who are interested
persons of the Adviser and other than those who are interested persons of the
distributor of the Fund but not of the Adviser, if the distributor has agreed
to pay such compensation), charges and expenses of independent accountants, of
legal counsel and of any transfer or dividend disbursing agent, costs of

federal securities laws, miscellaneous expenses and all taxes and fees to
federal, state or other governmental agencies on account of the registration of
securities issued by the Fund, filing of corporate documents or otherwise.  The
Fund shall not pay or incur any obligation for any management or administrative
expenses for which the Fund intends to seek reimbursement from the Adviser
without first obtaining the written approval of the Adviser.  The Adviser shall
arrange, if desired by the Fund, for officers or employees of the Adviser to
serve, without compensation from the Fund, as trustees, officers or agents of
the Fund if duly elected or appointed to such positions and subject to their
individual consent and to any limitations imposed by law.

     4. Interested Persons.  Subject to applicable statutes and regulations, it
is understood that trustees, officers, shareholders and agents of the Fund are
or may be interested in the Adviser as directors, officers, shareholders,
agents or otherwise and that the directors, officers, shareholders and agents
of the Adviser may be interest in the Fund as trustees, officers, shareholders,

or of law, or for any loss suffered by the Fund in connection with the matters
to which this Agreement relates, except a loss resulting from willful
misfeasance, bad faith or gross negligence on the part of the Adviser in the
performance of its obligations and duties, or by reason of its reckless
disregard of its obligations and duties under this Agreement.

     6. (a)  Term.  This Agreement shall become effective on the date hereof
and shall remain in full force until the second anniversary of the date hereof
unless sooner terminated as hereinafter provided.  This Agreement shall
continue in force from year to year thereafter, but only as long as such
continuance is specifically approved as least annually in the manner required

event of its assignment.  This Agreement may be terminated at any time without
the payment of any penalty by the Fund or by the Adviser on sixty (60) days
written notice to the other party.  The Fund may effect termination by action
of the Board of Trustees or by vote of a majority of the outstanding shares of
stock of the Fund, accompanied by appropriate notice.  This Agreement may be
terminated at any time without the payment of any penalty and without advance

shares of the Fund in the event that it shall have been established by a court
of competent jurisdiction that the Adviser or any officer or director of the
Adviser has taken any action which results in a breach of the covenants of the
Adviser set forth herein.

        (c)  Payment upon Termination.  Termination of this Agreement shall not

and necessary facilities and equipment to the Fund, to provide administrative
services for the Fund, to render periodic reports to the Board of Trustees of
the Fund, and to permit any of its officers or employees to serve without

     (c) Independent Contractor.  The Adviser shall be deemed to be an

provided or authorized, shall have no authority to act for or represent the
Fund in any way or otherwise be deemed as agent of the Fund.

                      AVERAGE DAILY        % PER ANNUM              
                      ------------------  ---------------

                      First $100 million    0.500% 
                      Next $150 million     0.450% 
                      Next $250 million     0.425%

</TABLE>

   (b)  Expense Limitation.  The Adviser's compensation for any fiscal year
of the Fund shall be reduced by the amount, if any, by which the Fund's expense
for such fiscal year exceeds the most restrictive applicable expense
jurisdiction in which the Fund's shares are qualified for offer and sale, as
such limitations set forth in the most recent notice thereof furnished by the
Adviser to the Fund.  For purposes of this paragraph there shall be excluded
from computation of the Fund's expenses any amount borne directly or indirectly
by the Fund which is permitted to be excluded from the computation of such
limitation by such statute or regulatory authority.  If for any month expenses
of the Fund properly included in such calculation exceed 1/12 of the amount
permitted annually by the most restrictive applicable expense limitation, the
payment to the Adviser for that month shall be reduced, and, if necessary, the
Adviser shall make a refund payment to the Fund, so that the total net expense
for the month will not exceed 1/12 of such amount.  As of the end of the Fund's
fiscal year, however, the computations and payments shall be readjusted so that
the aggregate compensation payable to the Adviser for the year is equal to the
fee set forth in subsection (a) of this Section 2, diminished to the extent
necessary so that the expenses for the year do not exceed those permitted by
the applicable expense limitation.

     (c)  Determination of Net Asset Value.  The net asset value of the Fund
shall be calculated as of the close of the New York Stock Exchange on each day
the Exchange is open for trading or such other time or times as the trustees
may determine in accordance with the provisions of applicable law and of the
Declaration of Trust and By-Laws of the Trust, and resolutions of the Board of
Trustees of the Fund as from time to time in force.  For the purpose of the
foregoing computations, on each such day when net

<PAGE>   10

asset value is not calculated, the net asset value of a share of beneficial
interest of the Fund shall be deemed to be the net asset value of such share as
of the close of business of the last day on which such calculation was made.

        (d)  Proration.  For the month and year in which this Agreement becomes
effective or terminates, there shall be an appropriate proration of the
Adviser's fee on the basis of the number of days that the Agreement is in
effect during such month and year, respectively.

     3. Expenses.  In addition to the fee of the Adviser, the Fund shall assume
and pay any expenses for services rendered by a custodian for the safekeeping
of the Fund's securities or other property, for keeping its books of account,
for any other charges of the custodian and for calculating the net asset value
of the Fund as provided above.  The Adviser shall not be required to pay, and
the Fund shall assume and pay, the charges and expenses of its operations,
including compensation of the trustees (other than those who are interested
persons of the Adviser and other than those who are interested persons of the
distributor of the Fund but not of the Adviser, if the distributor has agreed
to pay such compensation), charges and expenses of independent accountants, of
legal counsel and of any transfer or dividend disbursing agent, costs of

expenses for which the Fund intends to seek reimbursement from the Adviser
without first obtaining the written approval of the Adviser.  The Adviser shall
arrange, if desired by the Fund, for officers or employees of the Adviser to
serve, without compensation from the Fund, as trustees, officers or agents of
the Fund if duly elected or appointed to such positions and subject to their

                         INVESTMENT ADVISORY AGREEMENT


     THIS INVESTMENT ADVISORY AGREEMENT dated as of October 31, 1996, by and  
between VAN KAMPEN AMERICAN CAPITAL MUNICIPAL INCOME FUND (the "Fund"), a
series of Van Kampen American Capital TAX FREE TRUST,   Delaware business trust
(the "Trust"), and VAN KAMPEN AMERICAN CAPITAL INVESTMENT ADVISORY CORP. (the
"Adviser"), a Delaware corporation.

     1. (a) Retention of Adviser by Fund.  The Fund hereby employs the Adviser
to act as the investment adviser for and to manage the investment and
reinvestment of the assets of the Fund in accordance with the Fund's investment
objective and policies and limitations, and to administer its affairs to the
extent requested by, and subject to the review and supervision of, the Board of
Trustees of the Fund for the period and upon the terms herein set forth.  The
investment of funds shall be subject to all applicable restrictions of
applicable law and of the Declaration of Trust and By-Laws of the Trust, and
resolutions of the Board of Trustees of the Fund as may from time to time be in
force and delivered or made available to the Adviser.

        (b) Adviser's Acceptance of Employment.  The Adviser accepts such
employment and agrees during such period to render such services, to supply
investment research and portfolio management (including without limitation the
selection of securities for the Fund to purchase, hold or sell and the
selection of brokers through whom the Fund's portfolio transactions are
executed, in accordance with the policies adopted by the Fund and its Board of
Trustees), to administer the business affairs of the Fund, to furnish offices
and necessary facilities and equipment to the Fund, to provide administrative
services for the Fund, to render periodic reports to the Board of Trustees of
the Fund, and to permit any of its officers or employees to serve without
compensation as trustees or officers of the Fund if elected to such positions.

        (c) Independent Contractor.  The Adviser shall be deemed to be an
independent contractor under this Agreement and, unless otherwise expressly
provided or authorized, shall have no authority to act for or represent the
Fund in any way or otherwise be deemed as agent of the Fund.

        (d) Non-Exclusive Agreement.  The services of the Adviser to the Fund
under this Agreement are not to be deemed exclusive, and the Adviser shall be
free to render similar services or other services to others so long as its
services hereunder are not impaired thereby.

     2. (a) Fee.  For the services and facilities described in Section 1, the
Fund will accrue daily and pay to the Adviser at the end of each calendar month
an investment management fee equal to a percentage of the average daily net
assets of the Fund as follows:

<TABLE>
<CAPTION>
                      AVERGAGE DAILY
                      NET ASSETS            % PER ANNUM
                      ------------------  ---------------
                      <S>                 <C>
                      First $500 million    0.50% of 1.00%
                      Over $500 million     0.45% of 1.00%
</TABLE>


        (b) Expense Limitation.  The Adviser's compensation for any fiscal year
of the Fund shall be reduced by the amount, if any, by which the Fund's expense
for such fiscal year exceeds the most restrictive applicable expense
jurisdiction in which the Fund's shares are qualified for offer and sale, as
such limitations set forth in the most recent notice thereof furnished by the
Adviser to the Fund.  For purposes of this paragraph there shall be excluded
from computation of the Fund's expenses any amount borne directly or indirectly
by the Fund which is permitted to be excluded from the computation of such
limitation by such statute or regulatory authority.  If for any month expenses
of the Fund properly included in such calculation exceed 1/12 of the amount
permitted annually by the most restrictive applicable expense limitation, the
payment to the Adviser for that month shall be reduced, and, if necessary, the
Adviser shall make a refund payment to the Fund, so that the total net expense
for the month will not exceed 1/12 of such amount.  As of the end of the Fund's
fiscal year, however, the computations and payments shall be readjusted so that
the aggregate compensation payable to the Adviser for the year is equal to the
fee set forth in subsection (a) of this Section 2, diminished to the extent
necessary so that the expenses for the year do not exceed those permitted by
the applicable expense limitation.

        (c) Determination of Net Asset Value.  The net asset value of the Fund
shall be calculated as of the close of the New York Stock Exchange on each day
the Exchange is open for trading or such other time or times as the trustees
may determine in accordance with the provisions of applicable law and of the
Declaration of Trust and By-Laws of the Trust, and resolutions of the Board of
Trustees of the Fund as from time to time in force.  For the purpose of the
foregoing computations, on each such day when net asset value is not
calculated, the net asset value of a share of beneficial interest of the Fund
shall be deemed to be the net asset


<PAGE>   14
value of such share as of the close of business of the last day on which such
calculation was made.

        (d)  Proration.  For the month and year in which this Agreement becomes
effective or terminates, there shall be an appropriate proration of the
Adviser's fee on the basis of the number of days that the Agreement is in
effect during such month and year, respectively.

     3. Expenses.  In addition to the fee of the Adviser, the Fund shall assume
and pay any expenses for services rendered by a custodian for the safekeeping
of the Fund's securities or other property, for keeping its books of account,
for any other charges of the custodian and for calculating the net asset value
of the Fund as provided above.  The Adviser shall not be required to pay, and
the Fund shall assume and pay, the charges and expenses of its operations,
including compensation of the trustees (other than those who are interested
persons of the Adviser and other than those who are interested persons of the
distributor of the Fund but not of the Adviser, if the distributor has agreed
to pay such compensation), charges and expenses of independent accountants, of
legal counsel and of any transfer or dividend disbursing agent, costs of
acquiring and disposing of portfolio securities, cost of listing shares of the
New York Stock Exchange or other exchange interest (if any) on obligations
incurred by the Fund, costs of share certificates, membership dues in the
Investment Company Institute or any similar organization, costs of reports and
notices to shareholders, costs of registering shares of the Fund under the
federal securities laws, miscellaneous expenses and all taxes and fees to
federal, state or other governmental agencies on account of the registration of
securities issued by the Fund, filing of corporate documents or otherwise.  The
Fund shall not pay or incur any obligation for any management or administrative
expenses for which the Fund intends to seek reimbursement from the Adviser
without first obtaining the written approval of the Adviser.  The Adviser shall
arrange, if desired by the Fund, for officers or employees of the Adviser to
serve, without compensation from the Fund, as trustees, officers or agents of
the Fund if duly elected or appointed to such positions and subject to their
individual consent and to any limitations imposed by law.

     4. Interested Persons.  Subject to applicable statutes and regulations, it
is understood that trustees, officers, shareholders and agents of the Fund are
or may be interested in the Adviser as directors, officers, shareholders,
agents or otherwise and that the directors, officers, shareholders and agents
of the Adviser may be interest in the Fund as trustees, officers, shareholders,

     5. Liability.  The Adviser shall not be liable for any error of judgment
or of law, or for any loss suffered by the Fund in connection with the matters
to which this Agreement relates, except a loss resulting from willful
misfeasance, bad faith or gross negligence on the part of the Adviser in the
performance of its obligations and duties, or by reason of its reckless
disregard of its obligations and duties under this Agreement.
     6. (a)  Term.  This Agreement shall become effective on the date hereof
and shall remain in full force until the second anniversary of the date hereof
unless sooner terminated as hereinafter provided.  This Agreement shall
continue in force from year to year thereafter, but only as long as such
continuance is specifically approved as least annually in the manner required
by the Investment Company Act of 1940, as amended.

        (b)  Termination.   This Agreement shall automatically terminate in the
event of its assignment.  This Agreement may be terminated at any time without
the payment of any penalty by the Fund or by the Adviser on sixty (60) days
written notice to the other party.  The Fund may effect termination by action
of the Board of Trustees or by vote of a majority of the outstanding shares of
stock of the Fund, accompanied by appropriate notice.  This Agreement may be
terminated at any time without the payment of any penalty and without advance
notice by the Board of Trustees or by vote of a majority of the outstanding
shares of the Fund in the event that it shall have been established by a court
of competent jurisdiction that the Adviser or any officer or director of the
Adviser has taken any action which results in a breach of the covenants of the
Adviser set forth herein.

        (c)  Payment upon Termination.  Termination of this Agreement shall not
affect the right of the Adviser to receive payment on any unpaid balance of the
compensation described in Section 2 earned prior to such termination.

     7. Severability.  If any provision of this Agreement shall be held or made
invalid by a court decision, statute, rule or otherwise, the remainder shall
not thereby affected.

liable hereunder, nor shall resort be had to their private property for the
satisfaction of

any obligation or claim hereunder and that any such resort may only be had upon

resolutions of the Board of Trustees of the Fund as may from time to time be in

        (b) Adviser's Acceptance of Employment.  The Adviser accepts such
employment and agrees during such period to render such services, to supply
investment research and portfolio management (including without limitation the
selection of securities for the Fund to purchase, hold or sell and the

and necessary facilities and equipment to the Fund, to provide administrative
services for the Fund, to render periodic reports to the Board of Trustees of
the Fund, and to permit any of its officers or employees to serve without
compensation as trustees or officers of the Fund if elected to such positions.

        (c) Independent Contractor.  The Adviser shall be deemed to be an
independent contractor under this Agreement and, unless otherwise expressly
provided or authorized, shall have no authority to act for or represent the
Fund in any way or otherwise be deemed as agent of the Fund.

        (d) Non-Exclusive Agreement.  The services of the Adviser to the Fund
under this Agreement are not to be deemed exclusive, and the Adviser shall be

     2. (a) Fee.  For the services and facilities described in Section 1, the

                      AVERAGE DAILY        
                      NET ASSETS            % PER ANNUM

                      Over $500 million    0.450 of 1.00%
</TABLE>


        (b) Expense Limitation.  The Adviser's compensation for any fiscal year
of the Fund shall be reduced by the amount, if any, by which the Fund's expense
for such fiscal year exceeds the most restrictive applicable expense
jurisdiction in which the Fund's shares are qualified for offer and sale, as
such limitations set forth in the most recent notice thereof furnished by the
Adviser to the Fund.  For purposes of this paragraph there shall be excluded
from computation of the Fund's expenses any amount borne directly or indirectly
by the Fund which is permitted to be excluded from the computation of such
limitation by such statute or regulatory authority.  If for any month expenses
of the Fund properly included in such calculation exceed 1/12 of the amount
permitted annually by the most restrictive applicable expense limitation, the
payment to the Adviser for that month shall be reduced, and, if necessary, the
Adviser shall make a refund payment to the Fund, so that the total net expense
for the month will not exceed 1/12 of such amount.  As of the end of the Fund's

necessary so that the expenses for the year do not exceed those permitted by
the applicable expense limitation.

        (c) Determination of Net Asset Value.  The net asset value of the Fund
shall be calculated as of the close of the New York Stock Exchange on each day
the Exchange is open for trading or such other time or times as the trustees
may determine in accordance with the provisions of applicable law and of the
Declaration of Trust and By-Laws of the Trust, and resolutions of the Board of
Trustees of the Fund as from time to time in force.  For the purpose of the
foregoing computations, on each such day when net asset value is not
calculated, the net asset value of a share of beneficial interest of the Fund
shall be deemed to be the net asset

<PAGE>   18
value of such share as of the close of business of the last day on which such
calculation was made.

        (d)  Proration.  For the month and year in which this Agreement becomes
effective or terminates, there shall be an appropriate proration of the
Adviser's fee on the basis of the number of days that the Agreement is in
effect during such month and year, respectively.

     3. Expenses.  In addition to the fee of the Adviser, the Fund shall assume
and pay any expenses for services rendered by a custodian for the safekeeping
of the Fund's securities or other property, for keeping its books of account,
for any other charges of the custodian and for calculating the net asset value
of the Fund as provided above.  The Adviser shall not be required to pay, and
the Fund shall assume and pay, the charges and expenses of its operations,

persons of the Adviser and other than those who are interested persons of the
distributor of the Fund but not of the Adviser, if the distributor has agreed

executed, in accordance with the policies adopted by the Fund and its Board of
Trustees), to administer the business affairs of the Fund, to furnish offices
and necessary facilities and equipment to the Fund, to provide administrative
services for the Fund, to render periodic reports to the Board of Trustees of
the Fund, and to permit any of its officers or employees to serve without
compensation as trustees or officers of the Fund if elected to such positions.

        (c) Independent Contractor.  The Adviser shall be deemed to be an
independent contractor under this Agreement and, unless otherwise expressly
provided or authorized, shall have no authority to act for or represent the
Fund in any way or otherwise be deemed as agent of the Fund.

        (d) Non-Exclusive Agreement.  The services of the Adviser to the Fund
under this Agreement are not to be deemed exclusive, and the Adviser shall be
free to render similar services or other services to others so long as its
services hereunder are not impaired thereby.

     2. (a) Fee.  For the services and facilities described in Section 1, the
Fund will accrue daily and pay to the Adviser at the end of each calendar month
an investment management fee equal to a percentage of the average daily net
assets of the Fund as follows:


<TABLE>
<CAPTION>
                                           
                      AVERAGE DAILY        
                      NET ASSETS           % PER ANNUM
                      ------------------  ---------------
                      <S>                 <C>
                      First $500 million   0.500 of 1.00%
                      Over $500 million    0.450 of 1.00%
</TABLE>


        (b) Expense Limitation.  The Adviser's compensation for any fiscal year
of the Fund shall be reduced by the amount, if any, by which the Fund's expense
for such fiscal year exceeds the most restrictive applicable expense
jurisdiction in which the Fund's shares are qualified for offer and sale, as
such limitations set forth in the most recent notice thereof furnished by the
Adviser to the Fund.  For purposes of this paragraph there shall be excluded
from computation of the Fund's expenses any amount borne directly or indirectly
by the Fund which is permitted to be excluded from the computation of such
limitation by such statute or regulatory authority.  If for any month expenses
of the Fund properly included in such calculation exceed 1/12 of the amount
permitted annually by the most restrictive applicable expense limitation, the
payment to the Adviser for that month shall be reduced, and, if necessary, the
Adviser shall make a refund payment to the Fund, so that the total net expense
for the month will not exceed 1/12 of such amount.  As of the end of the Fund's
fiscal year, however, the computations and payments shall be readjusted so that
the aggregate compensation payable to the Adviser for the year is equal to the
fee set forth in subsection (a) of this Section 2, diminished to the extent
necessary so that the expenses for the year do not exceed those permitted by
the applicable expense limitation.

        (c) Determination of Net Asset Value.  The net asset value of the Fund
shall be calculated as of the close of the New York Stock Exchange on each day
the Exchange is open for trading or such other time or times as the trustees
may determine in accordance with the provisions of applicable law and of the
Declaration of Trust and By-Laws of the Trust, and resolutions of the Board of
Trustees of the Fund as from time to time in force.  For the purpose of the
foregoing computations, on each such day when net asset value is not
calculated, the net asset value of a share of beneficial interest of the Fund
shall be deemed to be the net asset

<PAGE>   22

value of such share as of the close of business of the last day on which such
calculation was made.

        (d)  Proration.  For the month and year in which this Agreement becomes
effective or terminates, there shall be an appropriate proration of the
Adviser's fee on the basis of the number of days that the Agreement is in
effect during such month and year, respectively.

     3. Expenses.  In addition to the fee of the Adviser, the Fund shall assume
and pay any expenses for services rendered by a custodian for the safekeeping
of the Fund's securities or other property, for keeping its books of account,
for any other charges of the custodian and for calculating the net asset value
of the Fund as provided above.  The Adviser shall not be required to pay, and
the Fund shall assume and pay, the charges and expenses of its operations,
including compensation of the trustees (other than those who are interested
persons of the Adviser and other than those who are interested persons of the
distributor of the Fund but not of the Adviser, if the distributor has agreed
to pay such compensation), charges and expenses of independent accountants, of
legal counsel and of any transfer or dividend disbursing agent, costs of
acquiring and disposing of portfolio securities, cost of listing shares of the
New York Stock Exchange or other exchange interest (if any) on obligations
incurred by the Fund, costs of share certificates, membership dues in the
Investment Company Institute or any similar organization, costs of reports and
notices to shareholders, costs of registering shares of the Fund under the
federal securities laws, miscellaneous expenses and all taxes and fees to
federal, state or other governmental agencies on account of the registration of
securities issued by the Fund, filing of corporate documents or otherwise.  The
Fund shall not pay or incur any obligation for any management or administrative
expenses for which the Fund intends to seek reimbursement from the Adviser
without first obtaining the written approval of the Adviser.  The Adviser shall
arrange, if desired by the Fund, for officers or employees of the Adviser to
serve, without compensation from the Fund, as trustees, officers or agents of
the Fund if duly elected or appointed to such positions and subject to their
individual consent and to any limitations imposed by law.

     4. Interested Persons.  Subject to applicable statutes and regulations, it
is understood that trustees, officers, shareholders and agents of the Fund are
or may be interested in the Adviser as directors, officers, shareholders,
agents or otherwise and that the directors, officers, shareholders and agents
of the Adviser may be interest in the Fund as trustees, officers, shareholders,
agents or otherwise.

     5. Liability.  The Adviser shall not be liable for any error of judgment
or of law, or for any loss suffered by the Fund in connection with the matters
to which this Agreement relates, except a loss resulting from willful
misfeasance, bad faith or gross negligence on the part of the Adviser in the
performance of its obligations and duties, or by reason of its reckless
disregard of its obligations and duties under this Agreement.

     6. (a)  Term.  This Agreement shall become effective on the date hereof
and shall remain in full force until the second anniversary of the date hereof
unless sooner terminated as hereinafter provided.  This Agreement shall
continue in force from year to year thereafter, but only as long as such
continuance is specifically approved as least annually in the manner required
by the Investment Company Act of 1940, as amended.

        (b)  Termination.   This Agreement shall automatically terminate in the
event of its assignment.  This Agreement may be terminated at any time without
the payment of any penalty by the Fund or by the Adviser on sixty (60) days
written notice to the other party.  The Fund may effect termination by action
of the Board of Trustees or by vote of a majority of the outstanding shares of
stock of the Fund, accompanied by appropriate notice.  This Agreement may be
terminated at any time without the payment of any penalty and without advance
notice by the Board of Trustees or by vote of a majority of the outstanding
shares of the Fund in the event that it shall have been established by a court
of competent jurisdiction that the Adviser or any officer or director of the
Adviser has taken any action which results in a breach of the covenants of the
Adviser set forth herein.

        (c)  Payment upon Termination.  Termination of this Agreement shall not
affect the right of the Adviser to receive payment on any unpaid balance of the
compensation described in Section 2 earned prior to such termination.

     7. Severability.  If any provision of this Agreement shall be held or made
invalid by a court decision, statute, rule or otherwise, the remainder shall
not thereby affected.

     8. Notices.  Any notice under this Agreement shall be in writing,
addressed and delivered or mailed, postage prepaid, to the other party at such
address as such other party may designate for the receipt of such notice.

     9. Disclaimer.  The Adviser acknowledges and agrees that, as provided by
Section 8.1 of the Declaration of Trust of the Trust, (i) this Agreement has
been executed by officers of the Trust in their capacity as officers, and not
individually, and (ii) the shareholders, trustees, officers, employees and
other agents of the Trust and the Fund shall not personally be bound by or
liable hereunder, nor shall resort be had to their private property for the
satisfaction of

<PAGE>   23

any obligation or claim hereunder and that any such resort may only be had upon
the assets and property of the Fund.

     10. Governing Law.  All questions concerning the validity, meaning and
effect of this Agreement shall be determined in accordance with the laws
(without giving effect to the conflict-of-law principles thereof) of the State

to act as the investment adviser for and to manage the investment and
reinvestment of the assets of the Fund in accordance with the Fund's investment
objective and policies and limitations, and to administer its affairs to the

investment of funds shall be subject to all applicable restrictions of
applicable law and of the Declaration of Trust and By-Laws of the Trust, and
resolutions of the Board of Trustees of the Fund as may from time to time be in
force and delivered or made available to the Adviser.

     (b) Adviser's Acceptance of Employment.  The Adviser accepts such
employment and agrees during such period to render such services, to supply
investment research and portfolio management (including without limitation the
selection of securities for the Fund to purchase, hold or sell and the
selection of brokers through whom the Fund's portfolio transactions are
executed, in accordance with the policies adopted by the Fund and its Board of
Trustees), to administer the business affairs of the Fund, to furnish offices
and necessary facilities and equipment to the Fund, to provide administrative
services for the Fund, to render periodic reports to the Board of Trustees of
the Fund, and to permit any of its officers or employees to serve without
compensation as trustees or officers of the Fund if elected to such positions.

     (c) Independent Contractor.  The Adviser shall be deemed to be an
independent contractor under this Agreement and, unless otherwise expressly
provided or authorized, shall have no authority to act for or represent the
Fund in any way or otherwise be deemed as agent of the Fund.

     (d) Non-Exclusive Agreement.  The services of the Adviser to the Fund
under this Agreement are not to be deemed exclusive, and the Adviser shall be
free to render similar services or other services to others so long as its
services hereunder are not impaired thereby.

     2. (a) Fee.  For the services and facilities described in Section 1, the
Fund will accrue daily and pay to the Adviser at the end of each calendar month
an investment management fee equal to a percentage of the average daily net
assets of the Fund as follows:


<TABLE>
<CAPTION>
                                           
                      AVERAGE DAILY        
                      NET ASSETS           % PER ANNUM
                      ------------------  ---------------
                      <S>                 <C>

                      Over $500 million     0.500 of 1.00%
</TABLE>


     (b)  Expense Limitation.  The Adviser's compensation for any fiscal year
of the Fund shall be reduced by the amount, if any, by which the Fund's expense
for such fiscal year exceeds the most restrictive applicable expense
jurisdiction in which the Fund's shares are qualified for offer and sale, as
such limitations set forth in the most recent notice thereof furnished by the
Adviser to the Fund.  For purposes of this paragraph there shall be excluded
from computation of the Fund's expenses any amount borne directly or indirectly
by the Fund which is permitted to be excluded from the computation of such
limitation by such statute or regulatory authority.  If for any month expenses
of the Fund properly included in such calculation exceed 1/12 of the amount
permitted annually by the most restrictive applicable expense limitation, the
payment to the Adviser for that month shall be reduced, and, if necessary, the
Adviser shall make a refund payment to the Fund, so that the total net expense
for the month will not exceed 1/12 of such amount.  As of the end of the Fund's
fiscal year, however, the computations and payments shall be readjusted so that
the aggregate compensation payable to the Adviser for the year is equal to the
fee set forth in subsection (a) of this Section 2, diminished to the extent
necessary so that the expenses for the year do not exceed those permitted by
the applicable expense limitation.

     (c)  Determination of Net Asset Value.  The net asset value of the Fund
shall be calculated as of the close of the New York Stock Exchange on each day
the Exchange is open for trading or such other time or times as the trustees
may determine in accordance with the provisions of applicable law and of the
Declaration of Trust and By-Laws of the Trust, and resolutions of the Board of
Trustees of the Fund as from time to time in force.  For the purpose of the
foregoing computations, on each such day when net asset value is not
calculated, the net asset value of a share of beneficial interest of the Fund
shall be deemed to be the net asset

<PAGE>   26
value of such share as of the close of business of the last day on which such
calculation was made.

        (d)  Proration.  For the month and year in which this Agreement becomes
effective or terminates, there shall be an appropriate proration of the
Adviser's fee on the basis of the number of days that the Agreement is in
effect during such month and year, respectively.

     3. Expenses.  In addition to the fee of the Adviser, the Fund shall assume
and pay any expenses for services rendered by a custodian for the safekeeping
of the Fund's securities or other property, for keeping its books of account,
for any other charges of the custodian and for calculating the net asset value
of the Fund as provided above.  The Adviser shall not be required to pay, and
the Fund shall assume and pay, the charges and expenses of its operations,

federal, state or other governmental agencies on account of the registration of
securities issued by the Fund, filing of corporate documents or otherwise.  The
Fund shall not pay or incur any obligation for any management or administrative
expenses for which the Fund intends to seek reimbursement from the Adviser
without first obtaining the written approval of the Adviser.  The Adviser shall
arrange, if desired by the Fund, for officers or employees of the Adviser to
serve, without compensation from the Fund, as trustees, officers or agents of
the Fund if duly elected or appointed to such positions and subject to their
individual consent and to any limitations imposed by law.

     4. Interested Persons.  Subject to applicable statutes and regulations, it
is understood that trustees, officers, shareholders and agents of the Fund are
or may be interested in the Adviser as directors, officers, shareholders,
agents or otherwise and that the directors, officers, shareholders and agents
of the Adviser may be interest in the Fund as trustees, officers, shareholders,

     5. Liability.  The Adviser shall not be liable for any error of judgment
or of law, or for any loss suffered by the Fund in connection with the matters
to which this Agreement relates, except a loss resulting from willful
misfeasance, bad faith or gross negligence on the part of the Adviser in the
performance of its obligations and duties, or by reason of its reckless
disregard of its obligations and duties under this Agreement.

     6. (a)  Term.  This Agreement shall become effective on the date hereof
and shall remain in full force until the second anniversary of the date hereof
unless sooner terminated as hereinafter provided.  This Agreement shall
continue in force from year to year thereafter, but only as long as such
continuance is specifically approved as least annually in the manner required
by the Investment Company Act of 1940, as amended.

event of its assignment.  This Agreement may be terminated at any time without
the payment of any penalty by the Fund or by the Adviser on sixty (60) days
written notice to the other party.  The Fund may effect termination by action
of the Board of Trustees or by vote of a majority of the outstanding shares of
stock of the Fund, accompanied by appropriate notice.  This Agreement may be
terminated at any time without the payment of any penalty and without advance
notice by the Board of Trustees or by vote of a majority of the outstanding
shares of the Fund in the event that it shall have been established by a court
of competent jurisdiction that the Adviser or any officer or director of the
Adviser has taken any action which results in a breach of the covenants of the
Adviser set forth herein.

        (c)  Payment upon Termination.  Termination of this Agreement shall not

any obligation or claim hereunder and that any such resort may only be had upon

force and delivered or made available to the Adviser.

     (b) Adviser's Acceptance of Employment.  The Adviser accepts such
employment and agrees during such period to render such services, to supply
investment research and portfolio management (including without limitation the
selection of securities for the Fund to purchase, hold or sell and the
selection of brokers through whom the Fund's portfolio transactions are
executed, in accordance with the policies adopted by the Fund and its Board of
Trustees), to administer the business affairs of the Fund, to furnish offices
and necessary facilities and equipment to the Fund, to provide administrative
services for the Fund, to render periodic reports to the Board of Trustees of
the Fund, and to permit any of its officers or employees to serve without
compensation as trustees or officers of the Fund if elected to such positions.

     (c) Independent Contractor.  The Adviser shall be deemed to be an
independent contractor under this Agreement and, unless otherwise expressly
provided or authorized, shall have no authority to act for or represent the
Fund in any way or otherwise be deemed as agent of the Fund.

     (d) Non-Exclusive Agreement.  The services of the Adviser to the Fund
under this Agreement are not to be deemed exclusive, and the Adviser shall be

     2. (a) Fee.  For the services and facilities described in Section 1, the

<CAPTION>
                                           
                      AVERAGE DAILY        
                      NET ASSETS            % PER ANNUM
                      ------------------  ---------------
                      <S>                 <C>

                      Over $500 million     0.500 of 1.00%
</TABLE>

     (b)  Expense Limitation.  The Adviser's compensation for any fiscal year
of the Fund shall be reduced by the amount, if any, by which the Fund's expense
for such fiscal year exceeds the most restrictive applicable expense
jurisdiction in which the Fund's shares are qualified for offer and sale, as
such limitations set forth in the most recent notice thereof furnished by the
Adviser to the Fund.  For purposes of this paragraph there shall be excluded
from computation of the Fund's expenses any amount borne directly or indirectly
by the Fund which is permitted to be excluded from the computation of such
limitation by such statute or regulatory authority.  If for any month expenses
of the Fund properly included in such calculation exceed 1/12 of the amount
permitted annually by the most restrictive applicable expense limitation, the
payment to the Adviser for that month shall be reduced, and, if necessary, the
Adviser shall make a refund payment to the Fund, so that the total net expense
for the month will not exceed 1/12 of such amount.  As of the end of the Fund's
fiscal year, however, the computations and payments shall be readjusted so that
the aggregate compensation payable to the Adviser for the year is equal to the
fee set forth in subsection (a) of this Section 2, diminished to the extent
necessary so that the expenses for the year do not exceed those permitted by
the applicable expense limitation.

     (c)  Determination of Net Asset Value.  The net asset value of the Fund
shall be calculated as of the close of the New York Stock Exchange on each day
the Exchange is open for trading or such other time or times as the trustees
may determine in accordance with the provisions of applicable law and of the
Declaration of Trust and By-Laws of the Trust, and resolutions of the Board of
Trustees of the Fund as from time to time in force.  For the purpose of the
foregoing computations, on each such day when net asset value is not
calculated, the net asset value of a share of beneficial interest of the Fund
shall be deemed to be the net asset value of such share as of the close of
business of the last day on which such calculation was made.
<PAGE>   30
        (d)  Proration.  For the month and year in which this Agreement becomes
effective or terminates, there shall be an appropriate proration of the
Adviser's fee on the basis of the number of days that the Agreement is in
effect during such month and year, respectively.

     3. Expenses.  In addition to the fee of the Adviser, the Fund shall assume
and pay any expenses for services rendered by a custodian for the safekeeping
of the Fund's securities or other property, for keeping its books of account,
for any other charges of the custodian and for calculating the net asset value
of the Fund as provided above.  The Adviser shall not be required to pay, and
the Fund shall assume and pay, the charges and expenses of its operations,
including compensation of the trustees (other than those who are interested
persons of the Adviser and other than those who are interested persons of the
distributor of the Fund but not of the Adviser, if the distributor has agreed
to pay such compensation), charges and expenses of independent accountants, of
legal counsel and of any transfer or dividend disbursing agent, costs of
acquiring and disposing of portfolio securities, cost of listing shares of the
New York Stock Exchange or other exchange interest (if any) on obligations

Investment Company Institute or any similar organization, costs of reports and
notices to shareholders, costs of registering shares of the Fund under the

expenses for which the Fund intends to seek reimbursement from the Adviser
without first obtaining the written approval of the Adviser.  The Adviser shall
arrange, if desired by the Fund, for officers or employees of the Adviser to
serve, without compensation from the Fund, as trustees, officers or agents of

                                                               EXHIBIT (6)(a)(i)


                       DISTRIBUTION AND SERVICE AGREEMENT


     THIS DISTRIBUTION AND SERVICE AGREEMENT dated as of October 31, 1996 (the
"Agreement") by and between VAN KAMPEN AMERICAN CAPITAL TAX FREE TRUST, a
Delaware business trust (the "Trust"), on behalf of its series, VAN KAMPEN
AMERICAN CAPITAL INSURED TAX FREE INCOME FUND (the "Fund"), and VAN KAMPEN
AMERICAN CAPITAL DISTRIBUTORS, INC., a Delaware corporation (the
"Distributor").

     1.  Appointment of Distributor.  The Fund appoints the Distributor as a
principal underwriter and exclusive distributor of each class of its shares of
beneficial interest (the "Shares") offered for sale from time to time pursuant
to the then current prospectus of the Fund, subject to different combinations
of front-end sales charges, distribution fees, service fees and contingent
deferred sales charges.  Classes of shares, if any, subject to a front-end
sales charge and a distribution and/or service fee are referred to herein as
"FESC Classes" and the Shares of such classes are referred to herein as "FESC
Shares."  Classes of shares, if any, subject to a contingent-deferred sales
charge and a distribution and/or a service fee are referred to herein as "CDSC
Classes" and Shares of such classes are referred to herein as "CDSC Shares."
Classes of shares, if any, subject to a front-end sales charge, a
contingent-deferred sales charge and a distribution and/or service fee are
referred to herein as "Combination Classes" and Shares of such class are
referred to herein as "Combination Shares."  The Fund reserves the right to
refuse at any time or times to sell Shares hereunder for any reason deemed
adequate by the Board of Trustees of the Fund.

     The Distributor will use its best efforts to sell, through its
organization and through other dealers and agents, the Shares which the
Distributor has the right to purchase under Section 2 hereof, but the
Distributor does not undertake to sell any specific number of Shares.

     The Distributor agrees that it will not take any long or short positions
in the Shares, except for long positions in those Shares purchased by the
Distributor in accordance with any systematic sales plan described in the then
current Prospectus of the Fund and except as permitted by Section 2 hereof, and
that so far as it can control the situation, it will prevent any of its
trustees, officers or shareholders from taking any long or short positions in
the Shares, except for legitimate investment purposes.

     2.  Sale of Shares to Distributor.  The Fund hereby grants to the
Distributor the exclusive right, except as herein otherwise provided, to
purchase Shares directly from the Fund upon the terms herein set forth.  Such
exclusive right hereby granted shall not apply to Shares issued or transferred
or sold at net asset value:  (a) in connection with the merger or consolidation
of the Fund with any other investment company or the acquisition by the Fund of
all or substantially all of the assets of or the outstanding Shares of any
investment company; (b) in connection with a pro rata distribution directly to
the holders of Fund Shares in the nature of a stock dividend or stock split or
in connection with any other recapitalization approved by the Board of
Trustees; (c) upon the exercise of purchase or subscription rights granted to
the holders of Shares on a pro rata basis; (d) in connection with the automatic
reinvestment of dividends and distributions from the Fund; or (e) in connection
with the issue and sale of Shares to trustees, officers and employees of the
Fund; to directors, officers and employees of the investment adviser of the
Fund or any principal underwriter (including the Distributor) of the Fund; to
retirees of the Distributor that purchased shares of any mutual fund
distributed by the Distributor prior to retirement; to directors, officers and
employees of Van Kampen American Capital, Inc. (formerly The Van Kampen Merritt
Companies, Inc.) (the parent of the Distributor), VK/AC Holding, Inc. (formerly
VKM Holdings, Inc.)(the parent of The Van Kampen Merritt Companies, Inc.) and
to the subsidiaries of VK/AC Holding, Inc.; and to any trust, pension,
profit-sharing or other benefit plan for any of the aforesaid persons as
permitted by Rule 22d-1 under the Investment Company Act of 1940 (the "1940
Act").

     The Distributor shall have the right to buy from the Fund the Shares
needed, but not more than the Shares needed (except for reasonable allowances
for clerical errors, delays and errors of 


                                      1
<PAGE>   2

transmission and cancellation of orders) to fill unconditional orders for Shares
received by the Distributor from dealers, agents and investors during each
period when particular net asset values and public offering prices are in effect
as provided in Section 3 hereof; and the price which the Distributor shall pay
for the Shares so purchased shall be the respective net asset value used in
determining the public offering price on which such orders were based.  The
Distributor shall notify the Fund at the end of each such period, or as soon
thereafter on that business day as the orders received in such period have been
compiled, of the number of Shares of each class that the Distributor elects to
purchase hereunder.

     3.  Public Offering Price.  The public offering price per Share shall be
determined in accordance with the then current Prospectus of the Fund.  In no
event shall the public offering price exceed the net asset value per Share,
plus, with respect to the FESC Shares,  a front-end sales charge not in excess
of the applicable maximum sales charge permitted under the Rules of Fair
Practice of the National Association of Securities Dealers, Inc., as in effect
from time to time.  The net asset value per share for each class of Shares,
respectively, shall be determined in the manner provided in the Declaration of
Trust and By-Laws of the Trust as then amended, the Certificate of Designation
with respect to the Fund, as amended, and in accordance with the then current
Prospectus of the Fund consistent with the terms and conditions of the
exemptive order with respect to the Fund (Release No. IC-19600) issued by the
Securities and Exchange Commission on July 28, 1993, as it may be amended from
time to time or succeeded by other exemptive orders or rules promulgated by the
Securities and Exchange Commission under the 1940 Act.  The Fund will cause
immediate notice to be given to the Distributor of each change in net asset
value as soon as it is determined.  Discounts to dealers purchasing FESC Shares
from the Distributor for resale and to brokers and other eligible agents making
sales of FESC Shares to investors and compensation payable from the Distributor
to dealers, brokers and other eligible agents making sales of CDSC Shares and
Combination Shares shall be set forth in the selling agreements between the
Distributor and such dealers or agents, respectively, as from time to time
amended, and, if such discounts and compensation are described in the then
current Prospectus for the Fund, shall be as so set forth.

     4.  Compliance with NASD Rules, SEC Orders, etc.  In selling Fund Shares,
the Distributor will in all respects duly comply with all state and federal
laws relating to the sale of such securities and with all applicable rules and
regulations of all regulatory bodies, including without limitation the Rules of
Fair Practice of the National Association of Securities Dealers, Inc., and all
applicable rules and regulations of the Securities and Exchange Commission
under the 1940 Act, and will indemnify and save the Fund harmless from any
damage or expense on account of any unlawful act by the Distributor or its
agents or employees.  The Distributor is not, however, to be responsible for
the acts of other dealers or agents, except to the extent that they shall be
acting for the Distributor or under its direction or authority.  None of the
Distributor, any dealer, any agent or any other person is authorized by the
Fund to give any information or to make any representations, other than those
contained in the Registration Statement or Prospectus heretofore or hereafter
filed with the Securities and Exchange Commission under the Securities Act of
1933, as amended (the "1933 Act") (as any such Registration Statement and
Prospectus may have been or may be amended from time to time), covering the
Shares, and in any supplemental information to any such Prospectus approved by
the Fund in connection with the offer or sale of Shares.  None of the
Distributor, any dealer, any broker or any other person is authorized to act as
agent for the Fund in connection with the offering or sale of Shares to the
public or otherwise.  All such sales shall be made by the Distributor as
principal for its own account.

     In selling Shares to investors, the Distributor will adopt and comply with
certain standards, as set forth in Exhibit III attached hereto as to when each
respective class of Shares may appropriately be sold to particular investors.
The Distributor will require every broker, dealer and other eligible agent
participating in the offering of the Shares to agree to adopt and comply with
such standards as a condition precedent to their participation in the offering.

   5.  Expenses.
    
           (a)  The Fund will pay or cause to be paid:

           (i)   all expenses in connection with the registration of Shares
                 under the federal securities laws, and the Fund will exercise
                 its best efforts to obtain said registration and qualification;

           (ii)  all expenses in connection with the printing of any notices of
                 shareholders' meetings, proxy and proxy statements and
                 enclosures therewith, as well as any other notice or
                 communication sent to shareholders in connection with any
                 meeting of the shareholders or otherwise, any annual,
                 semiannual or other reports or communications sent to the
                 shareholders, and the expenses of sending prospectuses relating
                 to the Shares to existing shareholders;

           (iii) all expenses of any federal or state original-issue tax or
                 transfer tax payable upon the issuance, transfer or delivery of
                 Shares from the Fund to the Distributor; and

           (iv)  the cost of preparing and issuing any Share certificates which
                 may be issued to represent Shares.

           (b)  The Distributor will pay the costs and expenses of qualifying
and maintaining qualification of the Shares for sale under the securities laws
of the various states.  The Distributor will also permit its officers and
employees to serve without compensation as trustees and officers of the Fund if
duly elected to such positions.

           (c)  The Fund shall reimburse the Distributor for out-of-pocket costs
and expenses actually incurred by it in connection with distribution of each
class of Shares respectively in accordance with the terms of a plan (the "12b-1
Plan") adopted by the Fund pursuant to Rule 12b-1 under the 1940 Act as such
12b-1 Plan may be in effect from time to time; provided, however, that no
payments shall be due or paid to the Distributor hereunder with respect to a
class of Shares unless and until this Agreement shall have been approved for
each such class by a majority of the Board of Trustees of the Fund and by a
majority of the "Disinterested Trustees" (as such term is defined in such 12b-1
Plan) by vote cast in person at a meeting called for the purpose of voting on
this Agreement.  A copy of such 12b-1 Plan as in effect on the date of this
Agreement is attached as Exhibit I hereto.  The Fund reserves the right to
terminate such 12b-1 Plan with respect to a class of Shares at any time, as
specified in the Plan.  The persons authorized to direct the payment of funds
pursuant to this Agreement and the 12b-1 Plan shall provide to the Fund's Board
of Trustees, and the Trustees shall review, at least quarterly, a written report
with respect to each of the classes of Shares of the amounts so paid and the
purposes for which such expenditures were made for each such class of Shares.

           (d)  The Fund shall compensate the Distributor for providing services
to, and the maintenance of, shareholder accounts in the Fund (including
prepaying service fees to eligible brokers, dealers and financial intermediaries
and expenses incurred in connection therewith) and the Distributor may pay as
agent for and on behalf of the Fund a service fee with respect to each class of
Shares to brokers, dealers and financial intermediaries for the provision of
shareholder services and the maintenance of shareholder accounts in the Fund in
the amount with respect to each class of Shares set forth from time to time in
the Fund's prospectus.  The Fund shall compensate the Distributor for such
expenses in accordance with the terms of a service plan (the "Service Plan"), as
such Service Plan may be in effect from time to time; provided, however, that no
service fee payments shall be due or paid to the Distributor hereunder with
respect to a class of Shares unless and until this Agreement shall have been
approved for each such class by a majority of the Board of Trustees of the Fund
and by a majority of the Disinterested Trustees by vote cast in person at a
meeting called for the purpose of voting on this Agreement.  A copy of such
Service Plan as in effect on the date of this Agreement is attached as Exhibit
II hereto.  The Fund reserves the right to terminate such Service Plan with
respect to a class of Shares at any time, as specified in the Plan.  The persons
authorized to direct the payment of funds 



                                      3
<PAGE>   4

pursuant to this Agreement and the Service Plan shall provide to the Fund's
Board of Trustees, and the Trustees shall review, at least quarterly, a written
report with respect to each of the classes of Shares of the amounts paid as
service fees for each such class of Shares.

     6.  Redemption of Shares.  In connection with the Fund's redemption of its
Shares, the Fund hereby authorizes the Distributor to repurchase, upon the
terms and conditions hereinafter set forth, as the Fund's agent and for the
Fund's account, such Shares as may be offered for sale to the Fund from time to
time by holders of such Shares or their agents.

           (a)  Subject to and in conformity with all applicable federal and
state legislation, any applicable rules of the National Association of
Securities Dealers, Inc., and any applicable rules and regulations of the
Securities and Exchange Commission under the 1940 Act, the Distributor may
accept offers of holders of Shares to resell such Shares to the Fund on such
terms and conditions and at such prices as described and provided for in the
then current Prospectus of the Fund.

           (b)  The Distributor agrees to notify the Fund at such times as the
Fund may specify of the number of each class of Shares, respectively,
repurchased for the Fund's account and the time or times of such repurchases,
and the Fund shall notify the Distributor of the prices and, in the case of a
class of CDSC Shares or Combination Shares, of the deferred sales charge as
described below, if any, applicable to repurchases of Shares of such class.

           (c)  The Fund shall have the right to suspend or revoke the foregoing
authorization at any time; unless otherwise stated, any such suspension or
revocation shall be effective forthwith upon receipt of notice thereof by
telegraph or by written instrument from any of the Fund's officers.  In the
event that the Distributor's authorization is, by the terms of such notice,
suspended for more than twenty-four hours or until further notice, the
authorization given by this Section 6 shall not be revived except by vote of the
Board of Trustees of the Fund.

           (d)  The Distributor agrees that all repurchases of Shares made by
the Distributor shall be made only as agent for the Fund's account and pursuant
to the terms and conditions herein set forth.

           (e)  The Fund agrees to authorize and direct its Custodian to pay,
for the Fund's account, the repurchase price (together with any applicable
contingent deferred sales charge) of any Shares so repurchased for the Fund
against the authorized transfer of book shares from an open account and against
delivery of any other documentation required by the Board of Trustees of the
Fund or, in the case of certificated Shares, against delivery of the
certificates representing such Shares in proper form for transfer to the Fund.

           (f)  The Distributor shall receive no commissions or other
compensation in respect of any repurchases of FESC Shares for the Fund under the
foregoing authorization and appointment as agent.  With respect to any
repurchase of CDSC Shares or Combination Shares, the Distributor shall receive
the deferred sales charge, if any, applicable to the respective class of Shares
that have been held for less than a specified period of time with respect to
such class as set forth from time to time in the Fund's Prospectus.  The
Distributor shall receive no other commission or other compensation in respect
of any repurchases of CDSC Shares or Combination Shares for the Fund under the
foregoing authorization and appointment as agent.

           (g)  If any FESC Shares sold to the Distributor under the terms of
this Agreement are redeemed or repurchased by the Fund or by the Distributor as
agent or are tendered for redemption within seven business days after the date
of the Distributor's confirmation of the original purchase by the Distributor,
the Distributor shall forfeit the amount above the net asset value received by
it in respect of such Shares, provided that the portion, if any, of such amount
re-allowed by the Distributor to dealers or agents shall be repayable to the
Fund only to the extent recovered by the Distributor from the dealer or agent
concerned.  The Distributor shall include in agreements with such dealers and
agents a corresponding provision for the forfeiture by them of their concession
with respect to FESC Shares purchased by them or their principals and redeemed
or repurchased by the Fund or by the Distributor as agent within seven business
days after the date of the Distributor's confirmation of such initial purchases.

     7.  Indemnification.  The Fund agrees to indemnify and hold harmless the
Distributor and each of its trustees and officers and each person, if any, who
controls the Distributor within the meaning of Section 15 of the 1933 Act
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, based upon the ground
that the registration statement, Prospectus, shareholder reports or other
information filed or made public by the Fund (as from time to time amended)
included an untrue statement of a material fact or omitted to state a material
fact required to be stated or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading under the 1933 Act or any other statute or the common law.  However,
the Fund does not agree to indemnify the Distributor or hold it harmless to the
extent that the statement or omission was made in reliance upon, and in
conformity with, information furnished to the Fund by or on behalf of the
Distributor.  In no case (i) is the indemnity of the Fund in favor of the
Distributor or any person indemnified to be deemed to protect the Distributor
or any person against any liability to the Fund or its securityholders to which
the Distributor or such person would otherwise be subject by reason of willful
misfeasance, bad faith or gross negligence in the performance of its duties or
by reason of its 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 Section with respect to any claim made against the
Distributor or any person indemnified unless the Distributor or any such person
shall have notified the Fund in writing of the claim within a reasonable time
after the summons or other first written notification giving information of the
nature of the claim shall have been served upon the Distributor or any such
person (or after the Distributor or the person shall have received notice of
service on any designated agent).  However, failure to notify the Fund of any
claim shall not relieve the Fund from any liability which it may have to the
Distributor or any person against whom such action is brought otherwise than on
account of its indemnity agreement contained in this paragraph.  The Fund shall
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 claims, but
if the Fund elects to assume the defense, the defense shall be conducted by
counsel chosen by it and satisfactory to the Distributor or person or persons,
defendant or defendants in the suit.  In the event the Fund elects to assume
the defense of any suit and retain counsel, the Distributor, officers or
trustees or controlling person or persons, defendant or defendants in the suit,
shall bear the fees and expenses of any additional counsel retained by them.
If the Fund does not elect to assume the defense of any suit, it will reimburse
the Distributor, officers or trustees or controlling person or persons,
defendant or defendants in the suit for the reasonable fees and expenses of any
counsel retained by them.  The Fund agrees to notify the Distributor promptly
of the commencement of any litigation or proceedings against it or any of its
officers or directors in connection with the issuance or sale of any of the
Shares.

     The Distributor also covenants and agrees that it will indemnify and hold
harmless the Fund and each of its trustees and officers and each person, if any,
who controls the Fund within the meaning of Section 15 of the 1933 Act against
any loss, liability, damage, claim or expense (including the reasonable cost of
investigating or defending any alleged loss, liability, damage, claim or expense
and reasonable counsel fees incurred in connection therewith) arising by reason
of any person acquiring any Shares, based upon the 1933 Act or any other statute
or common law, alleging any wrongful act of the Distributor or any of its
employees or alleging that the registration statement, Prospectus, shareholder
reports or other information filed or made public by the Fund (as from time to
time amended) included an untrue statement of a material fact or omitted to
state a material fact required to be stated or necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading, insofar as the statement or omission was made in reliance upon,
and in conformity with, information furnished to the Fund by or on behalf of the
Distributor.  In no case (i) is the indemnity of the Distributor in favor of the
Fund or any person indemnified to be deemed to protect the Fund or any such
person against any liability to which the Fund or such person would otherwise be
subject by reason of willful misfeasance, bad faith or gross negligence in the
performance of its duties or by reason of its reckless disregard of its
obligation and duties under this Amended Agreement, or (ii) is the Distributor
to be liable under its indemnity agreement contained in this paragraph with
respect to any claim made against the Fund or any person indemnified unless the
Fund or person, as the case may be, shall have notified the Distributor in
writing of the claim within a reasonable time after the summons or other first 



                                      5
<PAGE>   6

written notification giving information of the nature of the claim shall have
been served upon the Fund or person (or after the Fund or such person shall have
received notice of service on any designated agent). However, failure to notify
the Distributor of any claim shall not relieve the Distributor from any
liability which it may have to the Fund or any person against whom the action is
brought otherwise than on account of its indemnity agreement contained in this
paragraph.  In the case of any notice to the Distributor, it shall 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 the claim, but if the
Distributor elects to assume the defense, the defense shall be conducted by
counsel chosen by it and satisfactory to the Fund, to its officers and trustees
and to any controlling person or persons, defendant or defendants in the suit.
In the event that the Distributor elects to assume the defense of any suit and
retain counsel, the Fund or controlling persons, defendants in the suit, shall
bear the fees and expenses of any additional counsel retained by them.  If the
Distributor does not elect to assume the defense of any suit, it will reimburse
the Fund, officers and trustees or controlling person or persons, defendant or
defendants in the suit, for the reasonable fees and expenses of any counsel
retained by them.  The Distributor agrees to notify the Fund promptly of the
commencement of any litigation or proceedings against it in connection with the
issue and sale of any of the Shares.

     8.  Continuation, Amendment or Termination of This Agreement.  This
Agreement shall become effective on the Effective Date and thereafter shall
continue in full force and effect year to year with respect to each class of
Shares so long as such continuance is approved at least annually (i) by the
Board of Trustees of the Fund or by a vote of a majority of the outstanding
voting securities of the respective class of Shares of the Fund, and (ii) by
vote of a majority of the Trustees who are not parties to this Agreement or
interested persons in any such party (the "Independent Trustee") cast in person
at a meeting called for the purpose of voting on such approval, provided,
however, that (a) this Agreement may at any time be terminated with respect to
either class of Shares of the Fund without the payment of any penalty either by
vote of a majority of the Disinterested Trustees, or by vote of a majority of
the outstanding voting securities of the respective class of Shares of the
Fund, on written notice to the Distributor; (b) this Agreement shall
immediately terminate in the event of its assignment; and (c) this Agreement
may be terminated by the Distributor on ninety (90) days' written notice to the
Fund.  Upon termination of this Agreement with respect to either class of
Shares of the Fund, the obligations of the parties hereunder shall cease and
terminate with respect to such class of Shares as of the date of such
termination, except for any obligation to respond for a breach of this
Agreement committed prior to such termination.

     This Agreement may be amended with respect to either class of Shares at
any time by mutual consent of the parties, provided that such consent on the
part of the Fund shall have been approved (i) by the Board of Trustees of the
Fund, or by a vote of the majority of the outstanding voting securities of the
respective class of Shares of the Fund, and (ii) by vote of a majority of the
Independent Trustees cast in person at a meeting called for the purpose of
voting on such amendment.

     For the purpose of this section, the terms "vote of a majority of the
outstanding voting securities", "interested persons" and "assignment" shall

                                                              EXHIBIT (6)(a)(ii)


                       DISTRIBUTION AND SERVICE AGREEMENT


     THIS DISTRIBUTION AND SERVICE AGREEMENT dated as of October 31, 1996 (the
"Agreement") by and between VAN KAMPEN AMERICAN CAPITAL TAX FREE TRUST, a
Delaware business trust (the "Trust"), on behalf of its series, VAN KAMPEN
AMERICAN CAPITAL TAX FREE HIGH INCOME FUND (the "Fund"), and VAN KAMPEN
AMERICAN CAPITAL DISTRIBUTORS, INC., a Delaware corporation (the
"Distributor").

     1.  Appointment of Distributor.  The Fund appoints the Distributor as a
principal underwriter and exclusive distributor of each class of its shares of
beneficial interest (the "Shares") offered for sale from time to time pursuant
to the then current prospectus of the Fund, subject to different combinations
of front-end sales charges, distribution fees, service fees and contingent
deferred sales charges.  Classes of shares, if any, subject to a front-end
sales charge and a distribution and/or service fee are referred to herein as
"FESC Classes" and the Shares of such classes are referred to herein as "FESC
Shares."  Classes of shares, if any, subject to a contingent-deferred sales
charge and a distribution and/or a service fee are referred to herein as "CDSC
Classes" and Shares of such classes are referred to herein as "CDSC Shares."
Classes of shares, if any, subject to a front-end sales charge, a
contingent-deferred sales charge and a distribution and/or service fee are
referred to herein as "Combination Classes" and Shares of such class are
referred to herein as "Combination Shares."  The Fund reserves the right to
refuse at any time or times to sell Shares hereunder for any reason deemed
adequate by the Board of Trustees of the Fund.

     The Distributor will use its best efforts to sell, through its
organization and through other dealers and agents, the Shares which the
Distributor has the right to purchase under Section 2 hereof, but the
Distributor does not undertake to sell any specific number of Shares.

     The Distributor agrees that it will not take any long or short positions
in the Shares, except for long positions in those Shares purchased by the
Distributor in accordance with any systematic sales plan described in the then
current Prospectus of the Fund and except as permitted by Section 2 hereof, and
that so far as it can control the situation, it will prevent any of its
trustees, officers or shareholders from taking any long or short positions in
the Shares, except for legitimate investment purposes.

     2.  Sale of Shares to Distributor.  The Fund hereby grants to the
Distributor the exclusive right, except as herein otherwise provided, to
purchase Shares directly from the Fund upon the terms herein set forth.  Such
exclusive right hereby granted shall not apply to Shares issued or transferred
or sold at net asset value:  (a) in connection with the merger or consolidation
of the Fund with any other investment company or the acquisition by the Fund of
all or substantially all of the assets of or the outstanding Shares of any
investment company; (b) in connection with a pro rata distribution directly to
the holders of Fund Shares in the nature of a stock dividend or stock split or
in connection with any other recapitalization approved by the Board of
Trustees; (c) upon the exercise of purchase or subscription rights granted to
the holders of Shares on a pro rata basis; (d) in connection with the automatic
reinvestment of dividends and distributions from the Fund; or (e) in connection
with the issue and sale of Shares to trustees, officers and employees of the
Fund; to directors, officers and employees of the investment adviser of the
Fund or any principal underwriter (including the Distributor) of the Fund; to
retirees of the Distributor that purchased shares of any mutual fund
distributed by the Distributor prior to retirement; to directors, officers and
employees of Van Kampen American Capital, Inc. (formerly The Van Kampen Merritt
Companies, Inc.) (the parent of the Distributor), VK/AC Holding, Inc. (formerly
VKM Holdings, Inc.)(the parent of The Van Kampen Merritt Companies, Inc.) and
to the subsidiaries of VK/AC Holding, Inc.; and to any trust, pension,
profit-sharing or other benefit plan for any of the aforesaid persons as
permitted by Rule 22d-1 under the Investment Company Act of 1940 (the "1940
Act").

     The Distributor shall have the right to buy from the Fund the Shares
needed, but not more than the Shares needed (except for reasonable allowances
for clerical errors, delays and errors of 


                                      1
<PAGE>   9

transmission and cancellation of orders) to fill unconditional orders for Shares
received by the Distributor from dealers, agents and investors during each
period when particular net asset values and public offering prices are in effect
as provided in Section 3 hereof; and the price which the Distributor shall pay
for the Shares so purchased shall be the respective net asset value used in
determining the public offering price on which such orders were based.  The
Distributor shall notify the Fund at the end of each such period, or as soon
thereafter on that business day as the orders received in such period have been
compiled, of the number of Shares of each class that the Distributor elects to
purchase hereunder.

     3.  Public Offering Price.  The public offering price per Share shall be
determined in accordance with the then current Prospectus of the Fund.  In no
event shall the public offering price exceed the net asset value per Share,
plus, with respect to the FESC Shares,  a front-end sales charge not in excess
of the applicable maximum sales charge permitted under the Rules of Fair
Practice of the National Association of Securities Dealers, Inc., as in effect
from time to time.  The net asset value per share for each class of Shares,
respectively, shall be determined in the manner provided in the Declaration of
Trust and By-Laws of the Trust as then amended, the Certificate of Designation
with respect to the Fund, as amended, and in accordance with the then current
Prospectus of the Fund consistent with the terms and conditions of the
exemptive order with respect to the Fund (Release No. IC-19600) issued by the
Securities and Exchange Commission on July 28, 1993, as it may be amended from
time to time or succeeded by other exemptive orders or rules promulgated by the
Securities and Exchange Commission under the 1940 Act.  The Fund will cause
immediate notice to be given to the Distributor of each change in net asset
value as soon as it is determined.  Discounts to dealers purchasing FESC Shares
from the Distributor for resale and to brokers and other eligible agents making
sales of FESC Shares to investors and compensation payable from the Distributor
to dealers, brokers and other eligible agents making sales of CDSC Shares and
Combination Shares shall be set forth in the selling agreements between the
Distributor and such dealers or agents, respectively, as from time to time
amended, and, if such discounts and compensation are described in the then
current Prospectus for the Fund, shall be as so set forth.

     4.  Compliance with NASD Rules, SEC Orders, etc.  In selling Fund Shares,
the Distributor will in all respects duly comply with all state and federal
laws relating to the sale of such securities and with all applicable rules and
regulations of all regulatory bodies, including without limitation the Rules of
Fair Practice of the National Association of Securities Dealers, Inc., and all
applicable rules and regulations of the Securities and Exchange Commission
under the 1940 Act, and will indemnify and save the Fund harmless from any
damage or expense on account of any unlawful act by the Distributor or its
agents or employees.  The Distributor is not, however, to be responsible for
the acts of other dealers or agents, except to the extent that they shall be
acting for the Distributor or under its direction or authority.  None of the
Distributor, any dealer, any agent or any other person is authorized by the
Fund to give any information or to make any representations, other than those
contained in the Registration Statement or Prospectus heretofore or hereafter
filed with the Securities and Exchange Commission under the Securities Act of
1933, as amended (the "1933 Act") (as any such Registration Statement and
Prospectus may have been or may be amended from time to time), covering the
Shares, and in any supplemental information to any such Prospectus approved by
the Fund in connection with the offer or sale of Shares.  None of the
Distributor, any dealer, any broker or any other person is authorized to act as
agent for the Fund in connection with the offering or sale of Shares to the
public or otherwise.  All such sales shall be made by the Distributor as
principal for its own account.

     In selling Shares to investors, the Distributor will adopt and comply with
certain standards, as set forth in Exhibit III attached hereto as to when each
respective class of Shares may appropriately be sold to particular investors.
The Distributor will require every broker, dealer and other eligible agent
participating in the offering of the Shares to agree to adopt and comply with
such standards as a condition precedent to their participation in the offering.

   5.  Expenses.
    
           (a)  The Fund will pay or cause to be paid:

           (i)   all expenses in connection with the registration of Shares
                 under the federal securities laws, and the Fund will exercise
                 its best efforts to obtain said registration and qualification;

           (ii)  all expenses in connection with the printing of any notices of
                 shareholders' meetings, proxy and proxy statements and
                 enclosures therewith, as well as any other notice or
                 communication sent to shareholders in connection with any
                 meeting of the shareholders or otherwise, any annual,
                 semiannual or other reports or communications sent to the
                 shareholders, and the expenses of sending prospectuses relating
                 to the Shares to existing shareholders;

           (iii) all expenses of any federal or state original-issue tax or
                 transfer tax payable upon the issuance, transfer or delivery of
                 Shares from the Fund to the Distributor; and

           (iv)  the cost of preparing and issuing any Share certificates which
                 may be issued to represent Shares.

           (b)  The Distributor will pay the costs and expenses of qualifying
and maintaining qualification of the Shares for sale under the securities laws
of the various states.  The Distributor will also permit its officers and
employees to serve without compensation as trustees and officers of the Fund if
duly elected to such positions.

           (c)  The Fund shall reimburse the Distributor for out-of-pocket costs
and expenses actually incurred by it in connection with distribution of each
class of Shares respectively in accordance with the terms of a plan (the "12b-1
Plan") adopted by the Fund pursuant to Rule 12b-1 under the 1940 Act as such
12b-1 Plan may be in effect from time to time; provided, however, that no
payments shall be due or paid to the Distributor hereunder with respect to a
class of Shares unless and until this Agreement shall have been approved for
each such class by a majority of the Board of Trustees of the Fund and by a
majority of the "Disinterested Trustees" (as such term is defined in such 12b-1
Plan) by vote cast in person at a meeting called for the purpose of voting on
this Agreement.  A copy of such 12b-1 Plan as in effect on the date of this
Agreement is attached as Exhibit I hereto.  The Fund reserves the right to
terminate such 12b-1 Plan with respect to a class of Shares at any time, as
specified in the Plan.  The persons authorized to direct the payment of funds
pursuant to this Agreement and the 12b-1 Plan shall provide to the Fund's Board
of Trustees, and the Trustees shall review, at least quarterly, a written report
with respect to each of the classes of Shares of the amounts so paid and the
purposes for which such expenditures were made for each such class of Shares.

           (d)  The Fund shall compensate the Distributor for providing services
to, and the maintenance of, shareholder accounts in the Fund (including
prepaying service fees to eligible brokers, dealers and financial intermediaries
and expenses incurred in connection therewith) and the Distributor may pay as
agent for and on behalf of the Fund a service fee with respect to each class of
Shares to brokers, dealers and financial intermediaries for the provision of
shareholder services and the maintenance of shareholder accounts in the Fund in
the amount with respect to each class of Shares set forth from time to time in
the Fund's prospectus.  The Fund shall compensate the Distributor for such
expenses in accordance with the terms of a service plan (the "Service Plan"), as
such Service Plan may be in effect from time to time; provided, however, that no
service fee payments shall be due or paid to the Distributor hereunder with
respect to a class of Shares unless and until this Agreement shall have been
approved for each such class by a majority of the Board of Trustees of the Fund
and by a majority of the Disinterested Trustees by vote cast in person at a
meeting called for the purpose of voting on this Agreement.  A copy of such
Service Plan as in effect on the date of this Agreement is attached as Exhibit
II hereto.  The Fund reserves the right to terminate such Service Plan with
respect to a class of Shares at any time, as specified in the Plan.  The persons
authorized to direct the payment of funds 



                                      3
<PAGE>   11

pursuant to this Agreement and the Service Plan shall provide to the Fund's
Board of Trustees, and the Trustees shall review, at least quarterly, a written
report with respect to each of the classes of Shares of the amounts paid as
service fees for each such class of Shares.

     6.  Redemption of Shares.  In connection with the Fund's redemption of its
Shares, the Fund hereby authorizes the Distributor to repurchase, upon the
terms and conditions hereinafter set forth, as the Fund's agent and for the
Fund's account, such Shares as may be offered for sale to the Fund from time to
time by holders of such Shares or their agents.

           (a)  Subject to and in conformity with all applicable federal and
state legislation, any applicable rules of the National Association of
Securities Dealers, Inc., and any applicable rules and regulations of the
Securities and Exchange Commission under the 1940 Act, the Distributor may
accept offers of holders of Shares to resell such Shares to the Fund on such
terms and conditions and at such prices as described and provided for in the
then current Prospectus of the Fund.

           (b)  The Distributor agrees to notify the Fund at such times as the
Fund may specify of the number of each class of Shares, respectively,
repurchased for the Fund's account and the time or times of such repurchases,
and the Fund shall notify the Distributor of the prices and, in the case of a
class of CDSC Shares or Combination Shares, of the deferred sales charge as
described below, if any, applicable to repurchases of Shares of such class.

           (c)  The Fund shall have the right to suspend or revoke the foregoing
authorization at any time; unless otherwise stated, any such suspension or
revocation shall be effective forthwith upon receipt of notice thereof by
telegraph or by written instrument from any of the Fund's officers.  In the
event that the Distributor's authorization is, by the terms of such notice,
suspended for more than twenty-four hours or until further notice, the
authorization given by this Section 6 shall not be revived except by vote of the
Board of Trustees of the Fund.

           (d)  The Distributor agrees that all repurchases of Shares made by
the Distributor shall be made only as agent for the Fund's account and pursuant
to the terms and conditions herein set forth.

           (e)  The Fund agrees to authorize and direct its Custodian to pay,
for the Fund's account, the repurchase price (together with any applicable
contingent deferred sales charge) of any Shares so repurchased for the Fund
against the authorized transfer of book shares from an open account and against
delivery of any other documentation required by the Board of Trustees of the
Fund or, in the case of certificated Shares, against delivery of the
certificates representing such Shares in proper form for transfer to the Fund.

           (f)  The Distributor shall receive no commissions or other
compensation in respect of any repurchases of FESC Shares for the Fund under the
foregoing authorization and appointment as agent.  With respect to any
repurchase of CDSC Shares or Combination Shares, the Distributor shall receive
the deferred sales charge, if any, applicable to the respective class of Shares
that have been held for less than a specified period of time with respect to
such class as set forth from time to time in the Fund's Prospectus.  The
Distributor shall receive no other commission or other compensation in respect
of any repurchases of CDSC Shares or Combination Shares for the Fund under the
foregoing authorization and appointment as agent.

           (g)  If any FESC Shares sold to the Distributor under the terms of
this Agreement are redeemed or repurchased by the Fund or by the Distributor as
agent or are tendered for redemption within seven business days after the date
of the Distributor's confirmation of the original purchase by the Distributor,
the Distributor shall forfeit the amount above the net asset value received by
it in respect of such Shares, provided that the portion, if any, of such amount
re-allowed by the Distributor to dealers or agents shall be repayable to the
Fund only to the extent recovered by the Distributor from the dealer or agent
concerned.  The Distributor shall include in agreements with such dealers and
agents a corresponding provision for the forfeiture by them of their concession
with respect to FESC Shares purchased by them or their principals and redeemed
or repurchased by the Fund or by the Distributor as agent within seven business
days after the date of the Distributor's confirmation of such initial purchases.

     7.  Indemnification.  The Fund agrees to indemnify and hold harmless the
Distributor and each of its trustees and officers and each person, if any, who
controls the Distributor within the meaning of Section 15 of the 1933 Act
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, based upon the ground
that the registration statement, Prospectus, shareholder reports or other
information filed or made public by the Fund (as from time to time amended)
included an untrue statement of a material fact or omitted to state a material
fact required to be stated or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading under the 1933 Act or any other statute or the common law.  However,
the Fund does not agree to indemnify the Distributor or hold it harmless to the
extent that the statement or omission was made in reliance upon, and in
conformity with, information furnished to the Fund by or on behalf of the
Distributor.  In no case (i) is the indemnity of the Fund in favor of the
Distributor or any person indemnified to be deemed to protect the Distributor
or any person against any liability to the Fund or its securityholders to which
the Distributor or such person would otherwise be subject by reason of willful
misfeasance, bad faith or gross negligence in the performance of its duties or
by reason of its 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 Section with respect to any claim made against the
Distributor or any person indemnified unless the Distributor or any such person
shall have notified the Fund in writing of the claim within a reasonable time
after the summons or other first written notification giving information of the
nature of the claim shall have been served upon the Distributor or any such
person (or after the Distributor or the person shall have received notice of
service on any designated agent).  However, failure to notify the Fund of any
claim shall not relieve the Fund from any liability which it may have to the
Distributor or any person against whom such action is brought otherwise than on
account of its indemnity agreement contained in this paragraph.  The Fund shall
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 claims, but
if the Fund elects to assume the defense, the defense shall be conducted by
counsel chosen by it and satisfactory to the Distributor or person or persons,
defendant or defendants in the suit.  In the event the Fund elects to assume
the defense of any suit and retain counsel, the Distributor, officers or
trustees or controlling person or persons, defendant or defendants in the suit,
shall bear the fees and expenses of any additional counsel retained by them.
If the Fund does not elect to assume the defense of any suit, it will reimburse
the Distributor, officers or trustees or controlling person or persons,
defendant or defendants in the suit for the reasonable fees and expenses of any
counsel retained by them.  The Fund agrees to notify the Distributor promptly
of the commencement of any litigation or proceedings against it or any of its
officers or directors in connection with the issuance or sale of any of the
Shares.

     The Distributor also covenants and agrees that it will indemnify and hold
harmless the Fund and each of its trustees and officers and each person, if any,
who controls the Fund within the meaning of Section 15 of the 1933 Act against
any loss, liability, damage, claim or expense (including the reasonable cost of
investigating or defending any alleged loss, liability, damage, claim or expense
and reasonable counsel fees incurred in connection therewith) arising by reason
of any person acquiring any Shares, based upon the 1933 Act or any other statute
or common law, alleging any wrongful act of the Distributor or any of its
employees or alleging that the registration statement, Prospectus, shareholder
reports or other information filed or made public by the Fund (as from time to
time amended) included an untrue statement of a material fact or omitted to
state a material fact required to be stated or necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading, insofar as the statement or omission was made in reliance upon,
and in conformity with, information furnished to the Fund by or on behalf of the
Distributor.  In no case (i) is the indemnity of the Distributor in favor of the
Fund or any person indemnified to be deemed to protect the Fund or any such
person against any liability to which the Fund or such person would otherwise be
subject by reason of willful misfeasance, bad faith or gross negligence in the
performance of its duties or by reason of its reckless disregard of its
obligation and duties under this Amended Agreement, or (ii) is the Distributor
to be liable under its indemnity agreement contained in this paragraph with
respect to any claim made against the Fund or any person indemnified unless the
Fund or person, as the case may be, shall have notified the Distributor in
writing of the claim within a reasonable time after the summons or other first 



                                      5
<PAGE>   13

written notification giving information of the nature of the claim shall have
been served upon the Fund or person (or after the Fund or such person shall have
received notice of service on any designated agent). However, failure to notify
the Distributor of any claim shall not relieve the Distributor from any
liability which it may have to the Fund or any person against whom the action is
brought otherwise than on account of its indemnity agreement contained in this
paragraph.  In the case of any notice to the Distributor, it shall 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 the claim, but if the
Distributor elects to assume the defense, the defense shall be conducted by
counsel chosen by it and satisfactory to the Fund, to its officers and trustees
and to any controlling person or persons, defendant or defendants in the suit.
In the event that the Distributor elects to assume the defense of any suit and
retain counsel, the Fund or controlling persons, defendants in the suit, shall
bear the fees and expenses of any additional counsel retained by them.  If the
Distributor does not elect to assume the defense of any suit, it will reimburse
the Fund, officers and trustees or controlling person or persons, defendant or
defendants in the suit, for the reasonable fees and expenses of any counsel
retained by them.  The Distributor agrees to notify the Fund promptly of the
commencement of any litigation or proceedings against it in connection with the
issue and sale of any of the Shares.

     8.  Continuation, Amendment or Termination of This Agreement.  This
Agreement shall become effective on the Effective Date and thereafter shall
continue in full force and effect year to year with respect to each class of
Shares so long as such continuance is approved at least annually (i) by the
Board of Trustees of the Fund or by a vote of a majority of the outstanding
voting securities of the respective class of Shares of the Fund, and (ii) by
vote of a majority of the Trustees who are not parties to this Agreement or
interested persons in any such party (the "Independent Trustee") cast in person
at a meeting called for the purpose of voting on such approval, provided,
however, that (a) this Agreement may at any time be terminated with respect to
either class of Shares of the Fund without the payment of any penalty either by
vote of a majority of the Disinterested Trustees, or by vote of a majority of
the outstanding voting securities of the respective class of Shares of the
Fund, on written notice to the Distributor; (b) this Agreement shall
immediately terminate in the event of its assignment; and (c) this Agreement
may be terminated by the Distributor on ninety (90) days' written notice to the
Fund.  Upon termination of this Agreement with respect to either class of
Shares of the Fund, the obligations of the parties hereunder shall cease and
terminate with respect to such class of Shares as of the date of such
termination, except for any obligation to respond for a breach of this
Agreement committed prior to such termination.

     This Agreement may be amended with respect to either class of Shares at
any time by mutual consent of the parties, provided that such consent on the
part of the Fund shall have been approved (i) by the Board of Trustees of the
Fund, or by a vote of the majority of the outstanding voting securities of the
respective class of Shares of the Fund, and (ii) by vote of a majority of the
Independent Trustees cast in person at a meeting called for the purpose of
voting on such amendment.

     For the purpose of this section, the terms "vote of a majority of the
outstanding voting securities", "interested persons" and "assignment" shall
have the meanings defined in the 1940 Act, as amended.

     9.  Limited Liability of Shareholder.  Notwithstanding anything to the
contrary contained in this Agreement, you acknowledge and agree that, as
provided by Section 8.1 of the Agreement and Declaration of Trust of the Trust,
this Agreement is executed by the Trustees of the Trust and/or Officers of the
Fund by them not individually but as such Trustees and/or Officers, and the

                                                          EXHIBIT (6)(a)(iii)


                       DISTRIBUTION AND SERVICE AGREEMENT


     THIS DISTRIBUTION AND SERVICE AGREEMENT dated as of October 31, 1996 (the
"Agreement") by and between VAN KAMPEN AMERICAN CAPITAL TAX FREE TRUST, a
Delaware business trust (the "Trust"), on behalf of its series, VAN KAMPEN
AMERICAN CAPITAL CALIFORNIA INSURED TAX FREE FUND (the "Fund"), and VAN KAMPEN
AMERICAN CAPITAL DISTRIBUTORS, INC., a Delaware corporation (the
"Distributor").

     1.  Appointment of Distributor.  The Fund appoints the Distributor as a
principal underwriter and exclusive distributor of each class of its shares of
beneficial interest (the "Shares") offered for sale from time to time pursuant
to the then current prospectus of the Fund, subject to different combinations
of front-end sales charges, distribution fees, service fees and contingent
deferred sales charges.  Classes of shares, if any, subject to a front-end
sales charge and a distribution and/or service fee are referred to herein as
"FESC Classes" and the Shares of such classes are referred to herein as "FESC
Shares."  Classes of shares, if any, subject to a contingent-deferred sales
charge and a distribution and/or a service fee are referred to herein as "CDSC
Classes" and Shares of such classes are referred to herein as "CDSC Shares."
Classes of shares, if any, subject to a front-end sales charge, a
contingent-deferred sales charge and a distribution and/or service fee are
referred to herein as "Combination Classes" and Shares of such class are
referred to herein as "Combination Shares."  The Fund reserves the right to
refuse at any time or times to sell Shares hereunder for any reason deemed
adequate by the Board of Trustees of the Fund.

     The Distributor will use its best efforts to sell, through its
organization and through other dealers and agents, the Shares which the
Distributor has the right to purchase under Section 2 hereof, but the
Distributor does not undertake to sell any specific number of Shares.

     The Distributor agrees that it will not take any long or short positions
in the Shares, except for long positions in those Shares purchased by the
Distributor in accordance with any systematic sales plan described in the then
current Prospectus of the Fund and except as permitted by Section 2 hereof, and
that so far as it can control the situation, it will prevent any of its
trustees, officers or shareholders from taking any long or short positions in
the Shares, except for legitimate investment purposes.

     2.  Sale of Shares to Distributor.  The Fund hereby grants to the
Distributor the exclusive right, except as herein otherwise provided, to
purchase Shares directly from the Fund upon the terms herein set forth.  Such
exclusive right hereby granted shall not apply to Shares issued or transferred
or sold at net asset value:  (a) in connection with the merger or consolidation
of the Fund with any other investment company or the acquisition by the Fund of
all or substantially all of the assets of or the outstanding Shares of any
investment company; (b) in connection with a pro rata distribution directly to
the holders of Fund Shares in the nature of a stock dividend or stock split or
in connection with any other recapitalization approved by the Board of
Trustees; (c) upon the exercise of purchase or subscription rights granted to
the holders of Shares on a pro rata basis; (d) in connection with the automatic
reinvestment of dividends and distributions from the Fund; or (e) in connection
with the issue and sale of Shares to trustees, officers and employees of the
Fund; to directors, officers and employees of the investment adviser of the
Fund or any principal underwriter (including the Distributor) of the Fund; to
retirees of the Distributor that purchased shares of any mutual fund
distributed by the Distributor prior to retirement; to directors, officers and
employees of Van Kampen American Capital, Inc. (formerly The Van Kampen Merritt
Companies, Inc.) (the parent of the Distributor), VK/AC Holding, Inc. (formerly
VKM Holdings, Inc.)(the parent of The Van Kampen Merritt Companies, Inc.) and
to the subsidiaries of VK/AC Holding, Inc.; and to any trust, pension,
profit-sharing or other benefit plan for any of the aforesaid persons as
permitted by Rule 22d-1 under the Investment Company Act of 1940 (the "1940
Act").

     The Distributor shall have the right to buy from the Fund the Shares
needed, but not more than the Shares needed (except for reasonable allowances
for clerical errors, delays and errors of 


                                      1
<PAGE>   16

transmission and cancellation of orders) to fill unconditional orders for Shares
received by the Distributor from dealers, agents and investors during each
period when particular net asset values and public offering prices are in effect
as provided in Section 3 hereof; and the price which the Distributor shall pay
for the Shares so purchased shall be the respective net asset value used in
determining the public offering price on which such orders were based.  The
Distributor shall notify the Fund at the end of each such period, or as soon
thereafter on that business day as the orders received in such period have been
compiled, of the number of Shares of each class that the Distributor elects to
purchase hereunder.

     3.  Public Offering Price.  The public offering price per Share shall be
determined in accordance with the then current Prospectus of the Fund.  In no
event shall the public offering price exceed the net asset value per Share,
plus, with respect to the FESC Shares,  a front-end sales charge not in excess
of the applicable maximum sales charge permitted under the Rules of Fair
Practice of the National Association of Securities Dealers, Inc., as in effect
from time to time.  The net asset value per share for each class of Shares,
respectively, shall be determined in the manner provided in the Declaration of
Trust and By-Laws of the Trust as then amended, the Certificate of Designation
with respect to the Fund, as amended, and in accordance with the then current
Prospectus of the Fund consistent with the terms and conditions of the
exemptive order with respect to the Fund (Release No. IC-19600) issued by the
Securities and Exchange Commission on July 28, 1993, as it may be amended from
time to time or succeeded by other exemptive orders or rules promulgated by the
Securities and Exchange Commission under the 1940 Act.  The Fund will cause
immediate notice to be given to the Distributor of each change in net asset
value as soon as it is determined.  Discounts to dealers purchasing FESC Shares
from the Distributor for resale and to brokers and other eligible agents making
sales of FESC Shares to investors and compensation payable from the Distributor
to dealers, brokers and other eligible agents making sales of CDSC Shares and
Combination Shares shall be set forth in the selling agreements between the
Distributor and such dealers or agents, respectively, as from time to time
amended, and, if such discounts and compensation are described in the then
current Prospectus for the Fund, shall be as so set forth.

     4.  Compliance with NASD Rules, SEC Orders, etc.  In selling Fund Shares,
the Distributor will in all respects duly comply with all state and federal
laws relating to the sale of such securities and with all applicable rules and
regulations of all regulatory bodies, including without limitation the Rules of
Fair Practice of the National Association of Securities Dealers, Inc., and all
applicable rules and regulations of the Securities and Exchange Commission
under the 1940 Act, and will indemnify and save the Fund harmless from any
damage or expense on account of any unlawful act by the Distributor or its
agents or employees.  The Distributor is not, however, to be responsible for
the acts of other dealers or agents, except to the extent that they shall be
acting for the Distributor or under its direction or authority.  None of the
Distributor, any dealer, any agent or any other person is authorized by the
Fund to give any information or to make any representations, other than those
contained in the Registration Statement or Prospectus heretofore or hereafter
filed with the Securities and Exchange Commission under the Securities Act of
1933, as amended (the "1933 Act") (as any such Registration Statement and
Prospectus may have been or may be amended from time to time), covering the
Shares, and in any supplemental information to any such Prospectus approved by
the Fund in connection with the offer or sale of Shares.  None of the
Distributor, any dealer, any broker or any other person is authorized to act as
agent for the Fund in connection with the offering or sale of Shares to the
public or otherwise.  All such sales shall be made by the Distributor as
principal for its own account.

     In selling Shares to investors, the Distributor will adopt and comply with
certain standards, as set forth in Exhibit III attached hereto as to when each
respective class of Shares may appropriately be sold to particular investors.
The Distributor will require every broker, dealer and other eligible agent
participating in the offering of the Shares to agree to adopt and comply with
such standards as a condition precedent to their participation in the offering.

     5.  Expenses.

           (a)  The Fund will pay or cause to be paid:

           (i)     all expenses in connection with the registration of Shares
                   under the federal securities laws, and the Fund will exercise
                   its best efforts to obtain said registration and
                   qualification;

           (ii)    all expenses in connection with the printing of any notices
                   of shareholders' meetings, proxy and proxy statements and
                   enclosures therewith, as well as any other notice or
                   communication sent to shareholders in connection with any
                   meeting of the shareholders or otherwise, any annual,
                   semiannual or other reports or communications sent to the
                   shareholders, and the expenses of sending prospectuses
                   relating to the Shares to existing shareholders;

           (iii)   all expenses of any federal or state original-issue tax or
                   transfer tax payable upon the issuance, transfer or delivery
                   of Shares from the Fund to the Distributor; and

           (iv)    the cost of preparing and issuing any Share certificates
                   which may be issued to represent Shares.

           (b)  The Distributor will pay the costs and expenses of qualifying
and maintaining qualification of the Shares for sale under the securities laws
of the various states.  The Distributor will also permit its officers and
employees to serve without compensation as trustees and officers of the Fund if
duly elected to such positions.

           (c)  The Fund shall reimburse the Distributor for out-of-pocket costs
and expenses actually incurred by it in connection with distribution of each
class of Shares respectively in accordance with the terms of a plan (the "12b-1
Plan") adopted by the Fund pursuant to Rule 12b-1 under the 1940 Act as such
12b-1 Plan may be in effect from time to time; provided, however, that no
payments shall be due or paid to the Distributor hereunder with respect to a
class of Shares unless and until this Agreement shall have been approved for
each such class by a majority of the Board of Trustees of the Fund and by a
majority of the "Disinterested Trustees" (as such term is defined in such 12b-1
Plan) by vote cast in person at a meeting called for the purpose of voting on
this Agreement.  A copy of such 12b-1 Plan as in effect on the date of this
Agreement is attached as Exhibit I hereto.  The Fund reserves the right to
terminate such 12b-1 Plan with respect to a class of Shares at any time, as
specified in the Plan.  The persons authorized to direct the payment of funds
pursuant to this Agreement and the 12b-1 Plan shall provide to the Fund's Board
of Trustees, and the Trustees shall review, at least quarterly, a written report
with respect to each of the classes of Shares of the amounts so paid and the
purposes for which such expenditures were made for each such class of Shares.

           (d)  The Fund shall compensate the Distributor for providing services
to, and the maintenance of, shareholder accounts in the Fund (including
prepaying service fees to eligible brokers, dealers and financial intermediaries
and expenses incurred in connection therewith) and the Distributor may pay as
agent for and on behalf of the Fund a service fee with respect to each class of
Shares to brokers, dealers and financial intermediaries for the provision of
shareholder services and the maintenance of shareholder accounts in the Fund in
the amount with respect to each class of Shares set forth from time to time in
the Fund's prospectus.  The Fund shall compensate the Distributor for such
expenses in accordance with the terms of a service plan (the "Service Plan"), as
such Service Plan may be in effect from time to time; provided, however, that no
service fee payments shall be due or paid to the Distributor hereunder with
respect to a class of Shares unless and until this Agreement shall have been
approved for each such class by a majority of the Board of Trustees of the Fund
and by a majority of the Disinterested Trustees by vote cast in person at a
meeting called for the purpose of voting on this Agreement.  A copy of such
Service Plan as in effect on the date of this Agreement is attached as Exhibit
II hereto.  The Fund reserves the right to terminate such Service Plan with
respect to a class of Shares at any time, as specified in the Plan.  The persons
authorized to direct the payment of funds 


                                      3

<PAGE>   18

pursuant to this Agreement and the Service Plan shall provide to the Fund's
Board of Trustees, and the Trustees shall review, at least quarterly, a written
report with respect to each of the classes of Shares of the amounts paid as
service fees for each such class of Shares.

     6.  Redemption of Shares.  In connection with the Fund's redemption of its
Shares, the Fund hereby authorizes the Distributor to repurchase, upon the
terms and conditions hereinafter set forth, as the Fund's agent and for the
Fund's account, such Shares as may be offered for sale to the Fund from time to
time by holders of such Shares or their agents.

           (a)  Subject to and in conformity with all applicable federal and
state legislation, any applicable rules of the National Association of
Securities Dealers, Inc., and any applicable rules and regulations of the
Securities and Exchange Commission under the 1940 Act, the Distributor may
accept offers of holders of Shares to resell such Shares to the Fund on such
terms and conditions and at such prices as described and provided for in the
then current Prospectus of the Fund.

           (b)  The Distributor agrees to notify the Fund at such times as the
Fund may specify of the number of each class of Shares, respectively,
repurchased for the Fund's account and the time or times of such repurchases,
and the Fund shall notify the Distributor of the prices and, in the case of a
class of CDSC Shares or Combination Shares, of the deferred sales charge as
described below, if any, applicable to repurchases of Shares of such class.

           (c)  The Fund shall have the right to suspend or revoke the foregoing
authorization at any time; unless otherwise stated, any such suspension or
revocation shall be effective forthwith upon receipt of notice thereof by
telegraph or by written instrument from any of the Fund's officers.  In the
event that the Distributor's authorization is, by the terms of such notice,
suspended for more than twenty-four hours or until further notice, the
authorization given by this Section 6 shall not be revived except by vote of the
Board of Trustees of the Fund.

           (d)  The Distributor agrees that all repurchases of Shares made by
the Distributor shall be made only as agent for the Fund's account and pursuant
to the terms and conditions herein set forth.

           (e)  The Fund agrees to authorize and direct its Custodian to pay,
for the Fund's account, the repurchase price (together with any applicable
contingent deferred sales charge) of any Shares so repurchased for the Fund
against the authorized transfer of book shares from an open account and against
delivery of any other documentation required by the Board of Trustees of the
Fund or, in the case of certificated Shares, against delivery of the
certificates representing such Shares in proper form for transfer to the Fund.

           (f)  The Distributor shall receive no commissions or other
compensation in respect of any repurchases of FESC Shares for the Fund under the
foregoing authorization and appointment as agent.  With respect to any
repurchase of CDSC Shares or Combination Shares, the Distributor shall receive
the deferred sales charge, if any, applicable to the respective class of Shares
that have been held for less than a specified period of time with respect to
such class as set forth from time to time in the Fund's Prospectus.  The
Distributor shall receive no other commission or other compensation in respect
of any repurchases of CDSC Shares or Combination Shares for the Fund under the
foregoing authorization and appointment as agent.

           (g)  If any FESC Shares sold to the Distributor under the terms of
this Agreement are redeemed or repurchased by the Fund or by the Distributor as
agent or are tendered for redemption within seven business days after the date
of the Distributor's confirmation of the original purchase by the Distributor,
the Distributor shall forfeit the amount above the net asset value received by
it in respect of such Shares, provided that the portion, if any, of such amount
re-allowed by the Distributor to dealers or agents shall be repayable to the
Fund only to the extent recovered by the Distributor from the dealer or agent
concerned.  The Distributor shall include in agreements with such dealers and
agents a corresponding provision for the forfeiture by them of their concession
with respect to FESC Shares purchased by them or their principals and redeemed
or repurchased by the Fund or by the Distributor as agent within seven business
days after the date of the Distributor's confirmation of such initial purchases.

     7.  Indemnification.  The Fund agrees to indemnify and hold harmless the
Distributor and each of its trustees and officers and each person, if any, who
controls the Distributor within the meaning of Section 15 of the 1933 Act
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, based upon the ground
that the registration statement, Prospectus, shareholder reports or other
information filed or made public by the Fund (as from time to time amended)
included an untrue statement of a material fact or omitted to state a material
fact required to be stated or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading under the 1933 Act or any other statute or the common law.  However,
the Fund does not agree to indemnify the Distributor or hold it harmless to the
extent that the statement or omission was made in reliance upon, and in
conformity with, information furnished to the Fund by or on behalf of the
Distributor.  In no case (i) is the indemnity of the Fund in favor of the
Distributor or any person indemnified to be deemed to protect the Distributor
or any person against any liability to the Fund or its securityholders to which
the Distributor or such person would otherwise be subject by reason of willful
misfeasance, bad faith or gross negligence in the performance of its duties or
by reason of its 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 Section with respect to any claim made against the
Distributor or any person indemnified unless the Distributor or any such person
shall have notified the Fund in writing of the claim within a reasonable time
after the summons or other first written notification giving information of the
nature of the claim shall have been served upon the Distributor or any such
person (or after the Distributor or the person shall have received notice of
service on any designated agent).  However, failure to notify the Fund of any
claim shall not relieve the Fund from any liability which it may have to the
Distributor or any person against whom such action is brought otherwise than on
account of its indemnity agreement contained in this paragraph.  The Fund shall
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 claims, but
if the Fund elects to assume the defense, the defense shall be conducted by
counsel chosen by it and satisfactory to the Distributor or person or persons,
defendant or defendants in the suit.  In the event the Fund elects to assume
the defense of any suit and retain counsel, the Distributor, officers or
trustees or controlling person or persons, defendant or defendants in the suit,
shall bear the fees and expenses of any additional counsel retained by them.
If the Fund does not elect to assume the defense of any suit, it will reimburse
the Distributor, officers or trustees or controlling person or persons,
defendant or defendants in the suit for the reasonable fees and expenses of any
counsel retained by them.  The Fund agrees to notify the Distributor promptly
of the commencement of any litigation or proceedings against it or any of its
officers or directors in connection with the issuance or sale of any of the
Shares.

     The Distributor also covenants and agrees that it will indemnify and hold
harmless the Fund and each of its trustees and officers and each person, if any,
who controls the Fund within the meaning of Section 15 of the 1933 Act against
any loss, liability, damage, claim or expense (including the reasonable cost of
investigating or defending any alleged loss, liability, damage, claim or expense
and reasonable counsel fees incurred in connection therewith) arising by reason
of any person acquiring any Shares, based upon the 1933 Act or any other statute
or common law, alleging any wrongful act of the Distributor or any of its
employees or alleging that the registration statement, Prospectus, shareholder
reports or other information filed or made public by the Fund (as from time to
time amended) included an untrue statement of a material fact or omitted to
state a material fact required to be stated or necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading, insofar as the statement or omission was made in reliance upon,
and in conformity with, information furnished to the Fund by or on behalf of the
Distributor.  In no case (i) is the indemnity of the Distributor in favor of the
Fund or any person indemnified to be deemed to protect the Fund or any such
person against any liability to which the Fund or such person would otherwise be
subject by reason of willful misfeasance, bad faith or gross negligence in the
performance of its duties or by reason of its reckless disregard of its
obligation and duties under this Amended Agreement, or (ii) is the Distributor
to be liable under its indemnity agreement contained in this paragraph with
respect to any claim made against the Fund or any person indemnified unless the
Fund or person, as the case may be, shall have notified the Distributor in
writing of the claim within a reasonable time after the summons or other first 


                                      5
<PAGE>   20

written notification giving information of the nature of the claim shall have
been served upon the Fund or person (or after the Fund or such person shall have
received notice of service on any designated agent). However, failure to notify
the Distributor of any claim shall not relieve the Distributor from any
liability which it may have to the Fund or any person against whom the action is
brought otherwise than on account of its indemnity agreement contained in this
paragraph.  In the case of any notice to the Distributor, it shall 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 the claim, but if the
Distributor elects to assume the defense, the defense shall be conducted by
counsel chosen by it and satisfactory to the Fund, to its officers and trustees
and to any controlling person or persons, defendant or defendants in the suit.
In the event that the Distributor elects to assume the defense of any suit and
retain counsel, the Fund or controlling persons, defendants in the suit, shall
bear the fees and expenses of any additional counsel retained by them.  If the
Distributor does not elect to assume the defense of any suit, it will reimburse
the Fund, officers and trustees or controlling person or persons, defendant or
defendants in the suit, for the reasonable fees and expenses of any counsel
retained by them.  The Distributor agrees to notify the Fund promptly of the
commencement of any litigation or proceedings against it in connection with the
issue and sale of any of the Shares.

     8.  Continuation, Amendment or Termination of This Agreement.  This
Agreement shall become effective on the Effective Date and thereafter shall
continue in full force and effect year to year with respect to each class of
Shares so long as such continuance is approved at least annually (i) by the
Board of Trustees of the Fund or by a vote of a majority of the outstanding
voting securities of the respective class of Shares of the Fund, and (ii) by
vote of a majority of the Trustees who are not parties to this Agreement or
interested persons in any such party (the "Independent Trustee") cast in person
at a meeting called for the purpose of voting on such approval, provided,
however, that (a) this Agreement may at any time be terminated with respect to
either class of Shares of the Fund without the payment of any penalty either by
vote of a majority of the Disinterested Trustees, or by vote of a majority of
the outstanding voting securities of the respective class of Shares of the
Fund, on written notice to the Distributor; (b) this Agreement shall
immediately terminate in the event of its assignment; and (c) this Agreement
may be terminated by the Distributor on ninety (90) days' written notice to the
Fund.  Upon termination of this Agreement with respect to either class of
Shares of the Fund, the obligations of the parties hereunder shall cease and
terminate with respect to such class of Shares as of the date of such
termination, except for any obligation to respond for a breach of this
Agreement committed prior to such termination.

     This Agreement may be amended with respect to either class of Shares at
any time by mutual consent of the parties, provided that such consent on the
part of the Fund shall have been approved (i) by the Board of Trustees of the
Fund, or by a vote of the majority of the outstanding voting securities of the
respective class of Shares of the Fund, and (ii) by vote of a majority of the
Independent Trustees cast in person at a meeting called for the purpose of
voting on such amendment.

     For the purpose of this section, the terms "vote of a majority of the
outstanding voting securities", "interested persons" and "assignment" shall
have the meanings defined in the 1940 Act, as amended.

     9.  Limited Liability of Shareholder.  Notwithstanding anything to the
contrary contained in this Agreement, you acknowledge and agree that, as
provided by Section 8.1 of the Agreement and Declaration of Trust of the Trust,
this Agreement is executed by the Trustees of the Trust and/or Officers of the
Fund by them not individually but as such Trustees and/or Officers, and the
obligations of the Fund hereunder are not binding upon any of the Trustees,
Officers or Shareholders individually, but bind only the trust estate.

     10.  Notice.  Any notice under this Agreement shall be given in writing,
addressed and delivered, or mailed postpaid, to the other party at any office

                       DISTRIBUTION AND SERVICE AGREEMENT


     THIS DISTRIBUTION AND SERVICE AGREEMENT dated as of October 31, 1996 (the
"Agreement") by and between VAN KAMPEN AMERICAN CAPITAL TAX FREE TRUST, a
Delaware business trust (the "Trust"), on behalf of its series, VAN KAMPEN
AMERICAN CAPITAL MUNICIPAL INCOME FUND (the "Fund"), and VAN KAMPEN AMERICAN
CAPITAL DISTRIBUTORS, INC., a Delaware corporation (the "Distributor").

     1.  Appointment of Distributor.  The Fund appoints the Distributor as a
principal underwriter and exclusive distributor of each class of its shares of
beneficial interest (the "Shares") offered for sale from time to time pursuant
to the then current prospectus of the Fund, subject to different combinations
of front-end sales charges, distribution fees, service fees and contingent
deferred sales charges.  Classes of shares, if any, subject to a front-end
sales charge and a distribution and/or service fee are referred to herein as
"FESC Classes" and the Shares of such classes are referred to herein as "FESC
Shares."  Classes of shares, if any, subject to a contingent-deferred sales
charge and a distribution and/or a service fee are referred to herein as "CDSC
Classes" and Shares of such classes are referred to herein as "CDSC Shares."
Classes of shares, if any, subject to a front-end sales charge, a
contingent-deferred sales charge and a distribution and/or service fee are
referred to herein as "Combination Classes" and Shares of such class are
referred to herein as "Combination Shares."  The Fund reserves the right to
refuse at any time or times to sell Shares hereunder for any reason deemed
adequate by the Board of Trustees of the Fund.

     The Distributor will use its best efforts to sell, through its
organization and through other dealers and agents, the Shares which the
Distributor has the right to purchase under Section 2 hereof, but the
Distributor does not undertake to sell any specific number of Shares.

     The Distributor agrees that it will not take any long or short positions
in the Shares, except for long positions in those Shares purchased by the
Distributor in accordance with any systematic sales plan described in the then
current Prospectus of the Fund and except as permitted by Section 2 hereof, and
that so far as it can control the situation, it will prevent any of its
trustees, officers or shareholders from taking any long or short positions in
the Shares, except for legitimate investment purposes.

     2.  Sale of Shares to Distributor.  The Fund hereby grants to the
Distributor the exclusive right, except as herein otherwise provided, to
purchase Shares directly from the Fund upon the terms herein set forth.  Such
exclusive right hereby granted shall not apply to Shares issued or transferred
or sold at net asset value:  (a) in connection with the merger or consolidation
of the Fund with any other investment company or the acquisition by the Fund of
all or substantially all of the assets of or the outstanding Shares of any
investment company; (b) in connection with a pro rata distribution directly to
the holders of Fund Shares in the nature of a stock dividend or stock split or
in connection with any other recapitalization approved by the Board of
Trustees; (c) upon the exercise of purchase or subscription rights granted to
the holders of Shares on a pro rata basis; (d) in connection with the automatic
reinvestment of dividends and distributions from the Fund; or (e) in connection
with the issue and sale of Shares to trustees, officers and employees of the
Fund; to directors, officers and employees of the investment adviser of the
Fund or any principal underwriter (including the Distributor) of the Fund; to
retirees of the Distributor that purchased shares of any mutual fund
distributed by the Distributor prior to retirement; to directors, officers and
employees of Van Kampen American Capital, Inc. (formerly The Van Kampen Merritt
Companies, Inc.) (the parent of the Distributor), VK/AC Holding, Inc. (formerly
VKM Holdings, Inc.)(the parent of The Van Kampen Merritt Companies, Inc.) and
to the subsidiaries of VK/AC Holding, Inc.; and to any trust, pension,
profit-sharing or other benefit plan for any of the aforesaid persons as
permitted by Rule 22d-1 under the Investment Company Act of 1940 (the "1940
Act").

     The Distributor shall have the right to buy from the Fund the Shares
needed, but not more than the Shares needed (except for reasonable allowances
for clerical errors, delays and errors of 


                                      1

<PAGE>   23


transmission and cancellation of orders) to fill unconditional orders for
Shares received by the Distributor from dealers, agents and investors during
each period when particular net asset values and public offering prices are
in effect as provided in Section 3 hereof; and the price which the Distributor
shall pay for the Shares so purchased shall be the respective net asset value
used in determining the public offering price on which such orders were based. 
The Distributor shall notify the Fund at the end of each such period, or as
soon thereafter on that business day as the orders received in such period have
been compiled, of the number of Shares of each class that the Distributor
elects to purchase hereunder.

     3.  Public Offering Price.  The public offering price per Share shall be
determined in accordance with the then current Prospectus of the Fund.  In no
event shall the public offering price exceed the net asset value per Share,
plus, with respect to the FESC Shares,  a front-end sales charge not in excess
of the applicable maximum sales charge permitted under the Rules of Fair
Practice of the National Association of Securities Dealers, Inc., as in effect
from time to time.  The net asset value per share for each class of Shares,
respectively, shall be determined in the manner provided in the Declaration of
Trust and By-Laws of the Trust as then amended, the Certificate of Designation
with respect to the Fund, as amended, and in accordance with the then current
Prospectus of the Fund consistent with the terms and conditions of the
exemptive order with respect to the Fund (Release No. IC-19600) issued by the
Securities and Exchange Commission on July 28, 1993, as it may be amended from
time to time or succeeded by other exemptive orders or rules promulgated by the
Securities and Exchange Commission under the 1940 Act.  The Fund will cause
immediate notice to be given to the Distributor of each change in net asset
value as soon as it is determined.  Discounts to dealers purchasing FESC Shares
from the Distributor for resale and to brokers and other eligible agents making
sales of FESC Shares to investors and compensation payable from the Distributor
to dealers, brokers and other eligible agents making sales of CDSC Shares and
Combination Shares shall be set forth in the selling agreements between the
Distributor and such dealers or agents, respectively, as from time to time
amended, and, if such discounts and compensation are described in the then
current Prospectus for the Fund, shall be as so set forth.

     4.  Compliance with NASD Rules, SEC Orders, etc.  In selling Fund Shares,
the Distributor will in all respects duly comply with all state and federal
laws relating to the sale of such securities and with all applicable rules and
regulations of all regulatory bodies, including without limitation the Rules of
Fair Practice of the National Association of Securities Dealers, Inc., and all
applicable rules and regulations of the Securities and Exchange Commission
under the 1940 Act, and will indemnify and save the Fund harmless from any
damage or expense on account of any unlawful act by the Distributor or its
agents or employees.  The Distributor is not, however, to be responsible for
the acts of other dealers or agents, except to the extent that they shall be
acting for the Distributor or under its direction or authority.  None of the
Distributor, any dealer, any agent or any other person is authorized by the
Fund to give any information or to make any representations, other than those
contained in the Registration Statement or Prospectus heretofore or hereafter
filed with the Securities and Exchange Commission under the Securities Act of
1933, as amended (the "1933 Act") (as any such Registration Statement and
Prospectus may have been or may be amended from time to time), covering the
Shares, and in any supplemental information to any such Prospectus approved by
the Fund in connection with the offer or sale of Shares.  None of the
Distributor, any dealer, any broker or any other person is authorized to act as
agent for the Fund in connection with the offering or sale of Shares to the
public or otherwise.  All such sales shall be made by the Distributor as
principal for its own account.

     In selling Shares to investors, the Distributor will adopt and comply with
certain standards, as set forth in Exhibit III attached hereto as to when each
respective class of Shares may appropriately be sold to particular investors.
The Distributor will require every broker, dealer and other eligible agent
participating in the offering of the Shares to agree to adopt and comply with
such standards as a condition precedent to their participation in the offering.

5.  Expenses.

           (a)  The Fund will pay or cause to be paid:

           (i)    all expenses in connection with the registration of Shares
                  under the federal securities laws, and the Fund will exercise
                  its best efforts to obtain said registration and
                  qualification;

           (ii)   all expenses in connection with the printing of any notices of
                  shareholders' meetings, proxy and proxy statements and
                  enclosures therewith, as well as any other notice or
                  communication sent to shareholders in connection with any
                  meeting of the shareholders or otherwise, any annual,
                  semiannual or other reports or communications sent to the
                  shareholders, and the expenses of sending prospectuses
                  relating to the Shares to existing shareholders;

           (iii)  all expenses of any federal or state original-issue tax or
                  transfer tax payable upon the issuance, transfer or delivery
                  of Shares from the Fund to the Distributor; and

           (iv)   the cost of preparing and issuing any Share certificates which
                  may be issued to represent Shares.

           (b)  The Distributor will pay the costs and expenses of qualifying
and maintaining qualification of the Shares for sale under the securities laws
of the various states.  The Distributor will also permit its officers and
employees to serve without compensation as trustees and officers of the Fund if
duly elected to such positions.

           (c)  The Fund shall reimburse the Distributor for out-of-pocket costs
and expenses actually incurred by it in connection with distribution of each
class of Shares respectively in accordance with the terms of a plan (the "12b-1
Plan") adopted by the Fund pursuant to Rule 12b-1 under the 1940 Act as such
12b-1 Plan may be in effect from time to time; provided, however, that no
payments shall be due or paid to the Distributor hereunder with respect to a
class of Shares unless and until this Agreement shall have been approved for
each such class by a majority of the Board of Trustees of the Fund and by a
majority of the "Disinterested Trustees" (as such term is defined in such 12b-1
Plan) by vote cast in person at a meeting called for the purpose of voting on
this Agreement.  A copy of such 12b-1 Plan as in effect on the date of this
Agreement is attached as Exhibit I hereto.  The Fund reserves the right to
terminate such 12b-1 Plan with respect to a class of Shares at any time, as
specified in the Plan.  The persons authorized to direct the payment of funds
pursuant to this Agreement and the 12b-1 Plan shall provide to the Fund's Board
of Trustees, and the Trustees shall review, at least quarterly, a written report
with respect to each of the classes of Shares of the amounts so paid and the
purposes for which such expenditures were made for each such class of Shares.

           (d)  The Fund shall compensate the Distributor for providing services
to, and the maintenance of, shareholder accounts in the Fund (including
prepaying service fees to eligible brokers, dealers and financial intermediaries
and expenses incurred in connection therewith) and the Distributor may pay as
agent for and on behalf of the Fund a service fee with respect to each class of
Shares to brokers, dealers and financial intermediaries for the provision of
shareholder services and the maintenance of shareholder accounts in the Fund in
the amount with respect to each class of Shares set forth from time to time in
the Fund's prospectus.  The Fund shall compensate the Distributor for such
expenses in accordance with the terms of a service plan (the "Service Plan"), as
such Service Plan may be in effect from time to time; provided, however, that no
service fee payments shall be due or paid to the Distributor hereunder with
respect to a class of Shares unless and until this Agreement shall have been
approved for each such class by a majority of the Board of Trustees of the Fund
and by a majority of the Disinterested Trustees by vote cast in person at a
meeting called for the purpose of voting on this Agreement.  A copy of such
Service Plan as in effect on the date of this Agreement is attached as Exhibit
II hereto.  The Fund reserves the right to terminate such Service Plan with
respect to a class of Shares at any time, as specified in the Plan.  The persons
authorized to direct the payment of funds 


                                      3

<PAGE>   25

pursuant to this Agreement and the Service Plan shall provide to the Fund's
Board of Trustees, and the Trustees shall review, at least quarterly, a written
report with respect to each of the classes of Shares of the amounts paid as
service fees for each such class of Shares.

     6.  Redemption of Shares.  In connection with the Fund's redemption of its
Shares, the Fund hereby authorizes the Distributor to repurchase, upon the
terms and conditions hereinafter set forth, as the Fund's agent and for the
Fund's account, such Shares as may be offered for sale to the Fund from time to
time by holders of such Shares or their agents.

           (a)  Subject to and in conformity with all applicable federal and
state legislation, any applicable rules of the National Association of
Securities Dealers, Inc., and any applicable rules and regulations of the
Securities and Exchange Commission under the 1940 Act, the Distributor may
accept offers of holders of Shares to resell such Shares to the Fund on such
terms and conditions and at such prices as described and provided for in the
then current Prospectus of the Fund.

           (b)  The Distributor agrees to notify the Fund at such times as the
Fund may specify of the number of each class of Shares, respectively,
repurchased for the Fund's account and the time or times of such repurchases,
and the Fund shall notify the Distributor of the prices and, in the case of a
class of CDSC Shares or Combination Shares, of the deferred sales charge as
described below, if any, applicable to repurchases of Shares of such class.

           (c)  The Fund shall have the right to suspend or revoke the foregoing
authorization at any time; unless otherwise stated, any such suspension or
revocation shall be effective forthwith upon receipt of notice thereof by
telegraph or by written instrument from any of the Fund's officers.  In the
event that the Distributor's authorization is, by the terms of such notice,
suspended for more than twenty-four hours or until further notice, the
authorization given by this Section 6 shall not be revived except by vote of the
Board of Trustees of the Fund.

           (d)  The Distributor agrees that all repurchases of Shares made by
the Distributor shall be made only as agent for the Fund's account and pursuant
to the terms and conditions herein set forth.

           (e)  The Fund agrees to authorize and direct its Custodian to pay,
for the Fund's account, the repurchase price (together with any applicable
contingent deferred sales charge) of any Shares so repurchased for the Fund
against the authorized transfer of book shares from an open account and against
delivery of any other documentation required by the Board of Trustees of the
Fund or, in the case of certificated Shares, against delivery of the
certificates representing such Shares in proper form for transfer to the Fund.

           (f)  The Distributor shall receive no commissions or other
compensation in respect of any repurchases of FESC Shares for the Fund under the
foregoing authorization and appointment as agent.  With respect to any
repurchase of CDSC Shares or Combination Shares, the Distributor shall receive
the deferred sales charge, if any, applicable to the respective class of Shares
that have been held for less than a specified period of time with respect to
such class as set forth from time to time in the Fund's Prospectus.  The
Distributor shall receive no other commission or other compensation in respect
of any repurchases of CDSC Shares or Combination Shares for the Fund under the
foregoing authorization and appointment as agent.

           (g)  If any FESC Shares sold to the Distributor under the terms of
this Agreement are redeemed or repurchased by the Fund or by the Distributor as
agent or are tendered for redemption within seven business days after the date
of the Distributor's confirmation of the original purchase by the Distributor,
the Distributor shall forfeit the amount above the net asset value received by
it in respect of such Shares, provided that the portion, if any, of such amount
re-allowed by the Distributor to dealers or agents shall be repayable to the
Fund only to the extent recovered by the Distributor from the dealer or agent
concerned.  The Distributor shall include in agreements with such dealers and
agents a corresponding provision for the forfeiture by them of their concession
with respect to FESC Shares purchased by them or their principals and redeemed
or repurchased by the Fund or by the Distributor as agent within seven business
days after the date of the Distributor's confirmation of such initial purchases.

     7.  Indemnification.  The Fund agrees to indemnify and hold harmless the
Distributor and each of its trustees and officers and each person, if any, who
controls the Distributor within the meaning of Section 15 of the 1933 Act
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, based upon the ground
that the registration statement, Prospectus, shareholder reports or other
information filed or made public by the Fund (as from time to time amended)
included an untrue statement of a material fact or omitted to state a material
fact required to be stated or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading under the 1933 Act or any other statute or the common law.  However,
the Fund does not agree to indemnify the Distributor or hold it harmless to the
extent that the statement or omission was made in reliance upon, and in
conformity with, information furnished to the Fund by or on behalf of the
Distributor.  In no case (i) is the indemnity of the Fund in favor of the
Distributor or any person indemnified to be deemed to protect the Distributor
or any person against any liability to the Fund or its securityholders to which
the Distributor or such person would otherwise be subject by reason of willful
misfeasance, bad faith or gross negligence in the performance of its duties or
by reason of its 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 Section with respect to any claim made against the
Distributor or any person indemnified unless the Distributor or any such person
shall have notified the Fund in writing of the claim within a reasonable time
after the summons or other first written notification giving information of the
nature of the claim shall have been served upon the Distributor or any such
person (or after the Distributor or the person shall have received notice of
service on any designated agent).  However, failure to notify the Fund of any
claim shall not relieve the Fund from any liability which it may have to the
Distributor or any person against whom such action is brought otherwise than on
account of its indemnity agreement contained in this paragraph.  The Fund shall
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 claims, but
if the Fund elects to assume the defense, the defense shall be conducted by
counsel chosen by it and satisfactory to the Distributor or person or persons,
defendant or defendants in the suit.  In the event the Fund elects to assume
the defense of any suit and retain counsel, the Distributor, officers or
trustees or controlling person or persons, defendant or defendants in the suit,
shall bear the fees and expenses of any additional counsel retained by them.
If the Fund does not elect to assume the defense of any suit, it will reimburse
the Distributor, officers or trustees or controlling person or persons,
defendant or defendants in the suit for the reasonable fees and expenses of any
counsel retained by them.  The Fund agrees to notify the Distributor promptly
of the commencement of any litigation or proceedings against it or any of its
officers or directors in connection with the issuance or sale of any of the
Shares.

     The Distributor also covenants and agrees that it will indemnify and hold
harmless the Fund and each of its trustees and officers and each person, if any,
who controls the Fund within the meaning of Section 15 of the 1933 Act against
any loss, liability, damage, claim or expense (including the reasonable cost of
investigating or defending any alleged loss, liability, damage, claim or expense
and reasonable counsel fees incurred in connection therewith) arising by reason
of any person acquiring any Shares, based upon the 1933 Act or any other statute
or common law, alleging any wrongful act of the Distributor or any of its
employees or alleging that the registration statement, Prospectus, shareholder
reports or other information filed or made public by the Fund (as from time to
time amended) included an untrue statement of a material fact or omitted to
state a material fact required to be stated or necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading, insofar as the statement or omission was made in reliance upon,
and in conformity with, information furnished to the Fund by or on behalf of the
Distributor.  In no case (i) is the indemnity of the Distributor in favor of the
Fund or any person indemnified to be deemed to protect the Fund or any such
person against any liability to which the Fund or such person would otherwise be
subject by reason of willful misfeasance, bad faith or gross negligence in the
performance of its duties or by reason of its reckless disregard of its
obligation and duties under this Amended Agreement, or (ii) is the Distributor
to be liable under its indemnity agreement contained in this paragraph with
respect to any claim made against the Fund or any person indemnified unless the
Fund or person, as the case may be, shall have notified the Distributor in
writing of the claim within a reasonable time after the summons or other first 


                                      5
<PAGE>   27

written notification giving information of the nature of the claim shall have
been served upon the Fund or person (or after the Fund or such person shall have
received notice of service on any designated agent). However, failure to notify
the Distributor of any claim shall not relieve the Distributor from any
liability which it may have to the Fund or any person against whom the action is
brought otherwise than on account of its indemnity agreement contained in this
paragraph.  In the case of any notice to the Distributor, it shall 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 the claim, but if the
Distributor elects to assume the defense, the defense shall be conducted by
counsel chosen by it and satisfactory to the Fund, to its officers and trustees
and to any controlling person or persons, defendant or defendants in the suit.
In the event that the Distributor elects to assume the defense of any suit and
retain counsel, the Fund or controlling persons, defendants in the suit, shall
bear the fees and expenses of any additional counsel retained by them.  If the
Distributor does not elect to assume the defense of any suit, it will reimburse
the Fund, officers and trustees or controlling person or persons, defendant or
defendants in the suit, for the reasonable fees and expenses of any counsel
retained by them.  The Distributor agrees to notify the Fund promptly of the
commencement of any litigation or proceedings against it in connection with the
issue and sale of any of the Shares.

     8.  Continuation, Amendment or Termination of This Agreement.  This
Agreement shall become effective on the Effective Date and thereafter shall
continue in full force and effect year to year with respect to each class of
Shares so long as such continuance is approved at least annually (i) by the
Board of Trustees of the Fund or by a vote of a majority of the outstanding
voting securities of the respective class of Shares of the Fund, and (ii) by
vote of a majority of the Trustees who are not parties to this Agreement or
interested persons in any such party (the "Independent Trustee") cast in person
at a meeting called for the purpose of voting on such approval, provided,
however, that (a) this Agreement may at any time be terminated with respect to
either class of Shares of the Fund without the payment of any penalty either by
vote of a majority of the Disinterested Trustees, or by vote of a majority of
the outstanding voting securities of the respective class of Shares of the Fund,
on written notice to the Distributor; (b) this Agreement shall immediately
terminate in the event of its assignment; and (c) this Agreement may be
terminated by the Distributor on ninety (90) days' written notice to the Fund.
Upon termination of this Agreement with respect to either class of Shares of the
Fund, the obligations of the parties hereunder shall cease and terminate with
respect to such class of Shares as of the date of such termination, except for
any obligation to respond for a breach of this Agreement committed prior to such
termination.

     This Agreement may be amended with respect to either class of Shares at
any time by mutual consent of the parties, provided that such consent on the
part of the Fund shall have been approved (i) by the Board of Trustees of the
Fund, or by a vote of the majority of the outstanding voting securities of the
respective class of Shares of the Fund, and (ii) by vote of a majority of the
Independent Trustees cast in person at a meeting called for the purpose of
voting on such amendment.

     For the purpose of this section, the terms "vote of a majority of the
outstanding voting securities", "interested persons" and "assignment" shall
have the meanings defined in the 1940 Act, as amended.

     9.  Limited Liability of Shareholder.  Notwithstanding anything to the
contrary contained in this Agreement, you acknowledge and agree that, as
provided by Section 8.1 of the Agreement and Declaration of Trust of the Trust,
this Agreement is executed by the Trustees of the Trust and/or Officers of the
Fund by them not individually but as such Trustees and/or Officers, and the
obligations of the Fund hereunder are not binding upon any of the Trustees,
Officers or Shareholders individually, but bind only the trust estate.

     10.  Notice.  Any notice under this Agreement shall be given in writing,
addressed and delivered, or mailed postpaid, to the other party at any office
of such party or at such other address as such party shall have designated in
writing.

     11.  GOVERNING LAW.  THIS AGREEMENT SHALL BE CONSTRUED AND ENFORCED IN
ACCORDANCE WITH, AND THE RIGHTS OF THE PARTIES HERETO SHALL BE GOVERNED BY,

                                                            EXHIBIT (6)(a)(v)


                       DISTRIBUTION AND SERVICE AGREEMENT


     THIS DISTRIBUTION AND SERVICE AGREEMENT dated as of October 31, 1996 (the
"Agreement") by and between VAN KAMPEN AMERICAN CAPITAL TAX FREE TRUST, a
Delaware business trust (the "Trust"), on behalf of its series, VAN KAMPEN
AMERICAN CAPITAL INTERMEDIATE TERM MUNICIPAL INCOME FUND (the "Fund"), and VAN
KAMPEN AMERICAN CAPITAL DISTRIBUTORS, INC., a Delaware corporation (the
"Distributor").

     1.  Appointment of Distributor.  The Fund appoints the Distributor as a
principal underwriter and exclusive distributor of each class of its shares of
beneficial interest (the "Shares") offered for sale from time to time pursuant
to the then current prospectus of the Fund, subject to different combinations
of front-end sales charges, distribution fees, service fees and contingent
deferred sales charges.  Classes of shares, if any, subject to a front-end
sales charge and a distribution and/or service fee are referred to herein as
"FESC Classes" and the Shares of such classes are referred to herein as "FESC
Shares."  Classes of shares, if any, subject to a contingent-deferred sales
charge and a distribution and/or a service fee are referred to herein as "CDSC
Classes" and Shares of such classes are referred to herein as "CDSC Shares."
Classes of shares, if any, subject to a front-end sales charge, a
contingent-deferred sales charge and a distribution and/or service fee are
referred to herein as "Combination Classes" and Shares of such class are
referred to herein as "Combination Shares."  The Fund reserves the right to
refuse at any time or times to sell Shares hereunder for any reason deemed
adequate by the Board of Trustees of the Fund.

     The Distributor will use its best efforts to sell, through its
organization and through other dealers and agents, the Shares which the
Distributor has the right to purchase under Section 2 hereof, but the
Distributor does not undertake to sell any specific number of Shares.

     The Distributor agrees that it will not take any long or short positions
in the Shares, except for long positions in those Shares purchased by the
Distributor in accordance with any systematic sales plan described in the then
current Prospectus of the Fund and except as permitted by Section 2 hereof, and
that so far as it can control the situation, it will prevent any of its
trustees, officers or shareholders from taking any long or short positions in
the Shares, except for legitimate investment purposes.

     2.  Sale of Shares to Distributor.  The Fund hereby grants to the
Distributor the exclusive right, except as herein otherwise provided, to
purchase Shares directly from the Fund upon the terms herein set forth.  Such
exclusive right hereby granted shall not apply to Shares issued or transferred
or sold at net asset value:  (a) in connection with the merger or consolidation
of the Fund with any other investment company or the acquisition by the Fund of
all or substantially all of the assets of or the outstanding Shares of any
investment company; (b) in connection with a pro rata distribution directly to
the holders of Fund Shares in the nature of a stock dividend or stock split or
in connection with any other recapitalization approved by the Board of
Trustees; (c) upon the exercise of purchase or subscription rights granted to
the holders of Shares on a pro rata basis; (d) in connection with the automatic
reinvestment of dividends and distributions from the Fund; or (e) in connection
with the issue and sale of Shares to trustees, officers and employees of the
Fund; to directors, officers and employees of the investment adviser of the
Fund or any principal underwriter (including the Distributor) of the Fund; to
retirees of the Distributor that purchased shares of any mutual fund
distributed by the Distributor prior to retirement; to directors, officers and
employees of Van Kampen American Capital, Inc. (formerly The Van Kampen Merritt
Companies, Inc.) (the parent of the Distributor), VK/AC Holding, Inc. (formerly
VKM Holdings, Inc.)(the parent of The Van Kampen Merritt Companies, Inc.) and
to the subsidiaries of VK/AC Holding, Inc.; and to any trust, pension,
profit-sharing or other benefit plan for any of the aforesaid persons as
permitted by Rule 22d-1 under the Investment Company Act of 1940 (the "1940
Act").

     The Distributor shall have the right to buy from the Fund the Shares
needed, but not more than the Shares needed (except for reasonable allowances
for clerical errors, delays and errors of 


                                      1
<PAGE>   30

transmission and cancellation of orders) to fill unconditional orders for
Shares received by the Distributor from dealers, agents and investors
during each period when particular net asset values and public offering prices
are in effect as provided in Section 3 hereof; and the price which the
Distributor shall pay for the Shares so purchased shall be the respective net
asset value used in determining the public offering price on which such orders
were based.  The Distributor shall notify the Fund at the end of each such
period, or as soon thereafter on that business day as the orders received in
such period have been compiled, of the number of Shares of each class that the
Distributor elects to purchase hereunder.

     3.  Public Offering Price.  The public offering price per Share shall be
determined in accordance with the then current Prospectus of the Fund.  In no
event shall the public offering price exceed the net asset value per Share,
plus, with respect to the FESC Shares,  a front-end sales charge not in excess
of the applicable maximum sales charge permitted under the Rules of Fair
Practice of the National Association of Securities Dealers, Inc., as in effect
from time to time.  The net asset value per share for each class of Shares,
respectively, shall be determined in the manner provided in the Declaration of
Trust and By-Laws of the Trust as then amended, the Certificate of Designation
with respect to the Fund, as amended, and in accordance with the then current
Prospectus of the Fund consistent with the terms and conditions of the
exemptive order with respect to the Fund (Release No. IC-19600) issued by the
Securities and Exchange Commission on July 28, 1993, as it may be amended from
time to time or succeeded by other exemptive orders or rules promulgated by the
Securities and Exchange Commission under the 1940 Act.  The Fund will cause
immediate notice to be given to the Distributor of each change in net asset
value as soon as it is determined.  Discounts to dealers purchasing FESC Shares
from the Distributor for resale and to brokers and other eligible agents making
sales of FESC Shares to investors and compensation payable from the Distributor
to dealers, brokers and other eligible agents making sales of CDSC Shares and
Combination Shares shall be set forth in the selling agreements between the
Distributor and such dealers or agents, respectively, as from time to time
amended, and, if such discounts and compensation are described in the then
current Prospectus for the Fund, shall be as so set forth.

     4.  Compliance with NASD Rules, SEC Orders, etc.  In selling Fund Shares,
the Distributor will in all respects duly comply with all state and federal
laws relating to the sale of such securities and with all applicable rules and
regulations of all regulatory bodies, including without limitation the Rules of
Fair Practice of the National Association of Securities Dealers, Inc., and all
applicable rules and regulations of the Securities and Exchange Commission
under the 1940 Act, and will indemnify and save the Fund harmless from any
damage or expense on account of any unlawful act by the Distributor or its
agents or employees.  The Distributor is not, however, to be responsible for
the acts of other dealers or agents, except to the extent that they shall be
acting for the Distributor or under its direction or authority.  None of the
Distributor, any dealer, any agent or any other person is authorized by the
Fund to give any information or to make any representations, other than those
contained in the Registration Statement or Prospectus heretofore or hereafter
filed with the Securities and Exchange Commission under the Securities Act of
1933, as amended (the "1933 Act") (as any such Registration Statement and
Prospectus may have been or may be amended from time to time), covering the
Shares, and in any supplemental information to any such Prospectus approved by
the Fund in connection with the offer or sale of Shares.  None of the
Distributor, any dealer, any broker or any other person is authorized to act as
agent for the Fund in connection with the offering or sale of Shares to the
public or otherwise.  All such sales shall be made by the Distributor as
principal for its own account.

     In selling Shares to investors, the Distributor will adopt and comply with
certain standards, as set forth in Exhibit III attached hereto as to when each
respective class of Shares may appropriately be sold to particular investors.
The Distributor will require every broker, dealer and other eligible agent
participating in the offering of the Shares to agree to adopt and comply with
such standards as a condition precedent to their participation in the offering.

     5.  Expenses.

             (a) The Fund will pay or cause to be paid:

             (i)     all expenses in connection with the registration
                     of Shares under the federal securities laws, and the Fund
                     will exercise its best efforts to obtain said registration
                     and qualification;

            (ii)     all expenses in connection with the printing of
                     any notices of shareholders' meetings, proxy and proxy
                     statements and enclosures therewith, as well as any other
                     notice or communication sent to shareholders in    
                     connection with any meeting of the shareholders or
                     otherwise, any annual, semiannual or other reports or
                     communications sent to the shareholders, and the expenses
                     of sending prospectuses relating to the Shares to existing
                     shareholders;

           (iii)     all expenses of any federal or state
                     original-issue tax or transfer tax payable upon the
                     issuance,  transfer or delivery of Shares from the Fund to
                     the Distributor; and

            (iv)     the cost of preparing and issuing any Share
                     certificates which may be issued to represent Shares.

            (b)  The Distributor will pay the costs and expenses of qualifying
and maintaining qualification of the Shares for sale under the securities
laws of the various states.  The Distributor will also permit its officers and
employees to serve without compensation as trustees and officers of the Fund if
duly elected to such positions.

            (c)  The Fund shall reimburse the Distributor for out-of-pocket 
costs and expenses actually incurred by it in connection with distribution of
each class of Shares respectively in accordance with the terms of a plan (the
"12b-1  Plan") adopted by the Fund pursuant to Rule 12b-1 under the 1940 Act as
such 12b-1 Plan may be in effect from time to time; provided, however, that no
payments shall be due or paid to the Distributor hereunder with respect to a
class of Shares unless and until this Agreement shall have been approved for
each such class by a majority of the Board of Trustees of the Fund and by a
majority of the "Disinterested Trustees" (as such term is defined in such 12b-1
Plan) by vote cast in person at a meeting called for the purpose of voting on
this Agreement.  A copy of such 12b-1 Plan as in effect on the date of this
Agreement is attached as Exhibit I hereto.  The Fund reserves the right to
terminate such 12b-1 Plan with respect to a class of Shares at any time, as
specified in the Plan.  The persons authorized to direct the payment of funds
pursuant to this Agreement and the 12b-1 Plan shall provide to the Fund's Board
of Trustees, and the Trustees shall review, at least quarterly, a written
report with respect to each of the classes of Shares of the amounts so paid and
the purposes for which such expenditures were made for each such class of
Shares.

            (d)  The Fund shall compensate the Distributor for providing 
services to, and the maintenance of, shareholder accounts in the Fund
(including prepaying service fees to eligible brokers, dealers and financial
intermediaries and expenses incurred in connection therewith) and the
Distributor may pay as agent for and on behalf of the Fund a service fee
with respect to each class of Shares to brokers, dealers and financial
intermediaries for the provision of shareholder services and the maintenance of
shareholder accounts in the Fund in the amount with respect to each class of
Shares set forth from time to time in the Fund's prospectus.  The Fund shall
compensate the Distributor for such expenses in accordance with the terms of a
service plan (the "Service Plan"), as such Service Plan may be in effect from
time to time; provided, however, that no service fee payments shall be due or
paid to the Distributor hereunder with respect to a class of Shares unless and
until this Agreement shall have been approved for each such class by a majority
of the Board of Trustees of the Fund and by a majority of the Disinterested
Trustees by vote cast in person at a meeting called for the purpose of voting
on this Agreement.  A copy of such Service Plan as in effect on the date of
this Agreement is attached as Exhibit II hereto.  The Fund reserves the right
to terminate such Service Plan with respect to a class of Shares at any time,
as specified in the Plan.  The persons authorized to direct the payment of
funds 


                                      3

<PAGE>   32

pursuant to this Agreement and the Service Plan shall provide to the
Fund's Board of Trustees, and the Trustees shall review, at least quarterly, a
written report with respect to each of the classes of Shares of the amounts
paid as service fees for each such class of Shares.

     6.  Redemption of Shares.  In connection with the Fund's redemption of its
Shares, the Fund hereby authorizes the Distributor to repurchase, upon the
terms and conditions hereinafter set forth, as the Fund's agent and for the
Fund's account, such Shares as may be offered for sale to the Fund from time to
time by holders of such Shares or their agents.

     (a)  Subject to and in conformity with all applicable federal and state
legislation, any applicable rules of the National Association of Securities
Dealers, Inc., and any applicable rules and regulations of the Securities and
Exchange Commission under the 1940 Act, the Distributor may accept offers of
holders of Shares to resell such Shares to the Fund on such terms and
conditions and at such prices as described and provided for in the then current
Prospectus of the Fund.

     (b)  The Distributor agrees to notify the Fund at such times as the Fund
may specify of the number of each class of Shares, respectively, repurchased
for the Fund's account and the time or times of such repurchases, and the Fund
shall notify the Distributor of the prices and, in the case of a class of CDSC
Shares or Combination Shares, of the deferred sales charge as described below,
if any, applicable to repurchases of Shares of such class.

     (c)  The Fund shall have the right to suspend or revoke the foregoing
authorization at any time; unless otherwise stated, any such suspension or
revocation shall be effective forthwith upon receipt of notice thereof by
telegraph or by written instrument from any of the Fund's officers.  In the
event that the Distributor's authorization is, by the terms of such notice,
suspended for more than twenty-four hours or until further notice, the
authorization given by this Section 6 shall not be revived except by vote of
the Board of Trustees of the Fund.

     (d)  The Distributor agrees that all repurchases of Shares made by the
Distributor shall be made only as agent for the Fund's account and pursuant to
the terms and conditions herein set forth.

     (e)  The Fund agrees to authorize and direct its Custodian to pay, for the
Fund's account, the repurchase price (together with any applicable contingent
deferred sales charge) of any Shares so repurchased for the Fund against the
authorized transfer of book shares from an open account and against delivery of
any other documentation required by the Board of Trustees of the Fund or, in
the case of certificated Shares, against delivery of the certificates
representing such Shares in proper form for transfer to the Fund.

     (f)  The Distributor shall receive no commissions or other compensation in
respect of any repurchases of FESC Shares for the Fund under the foregoing
authorization and appointment as agent.  With respect to any repurchase of CDSC
Shares or Combination Shares, the Distributor shall receive the deferred sales
charge, if any, applicable to the respective class of Shares that have been
held for less than a specified period of time with respect to such class as set
forth from time to time in the Fund's Prospectus.  The Distributor shall
receive no other commission or other compensation in respect of any repurchases
of CDSC Shares or Combination Shares for the Fund under the foregoing
authorization and appointment as agent.

     (g)  If any FESC Shares sold to the Distributor under the terms of this
Agreement are redeemed or repurchased by the Fund or by the Distributor as
agent or are tendered for redemption within seven business days after the date  
of the Distributor's confirmation of the original purchase by the Distributor,
the Distributor shall forfeit the amount above the net asset value received by
it in respect of such Shares, provided that the portion, if any, of such amount
re-allowed by the Distributor to dealers or agents shall be repayable to the
Fund only to the extent recovered by the Distributor from the dealer or agent
concerned.  The Distributor shall include in agreements with such dealers and
agents a corresponding provision for the forfeiture by them of their concession
with respect to FESC Shares purchased by them or their principals and redeemed
or repurchased by the Fund or by the Distributor as agent within seven business
days after the date of the Distributor's confirmation of such initial
purchases.

     7.  Indemnification.  The Fund agrees to indemnify and hold harmless the
Distributor and each of its trustees and officers and each person, if any, who
controls the Distributor within the meaning of Section 15 of the 1933 Act
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, based upon the ground
that the registration statement, Prospectus, shareholder reports or other
information filed or made public by the Fund (as from time to time amended)
included an untrue statement of a material fact or omitted to state a material
fact required to be stated or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading under the 1933 Act or any other statute or the common law.  However,
the Fund does not agree to indemnify the Distributor or hold it harmless to the
extent that the statement or omission was made in reliance upon, and in
conformity with, information furnished to the Fund by or on behalf of the
Distributor.  In no case (i) is the indemnity of the Fund in favor of the
Distributor or any person indemnified to be deemed to protect the Distributor
or any person against any liability to the Fund or its securityholders to which
the Distributor or such person would otherwise be subject by reason of willful
misfeasance, bad faith or gross negligence in the performance of its duties or
by reason of its 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 Section with respect to any claim made against the
Distributor or any person indemnified unless the Distributor or any such person
shall have notified the Fund in writing of the claim within a reasonable time
after the summons or other first written notification giving information of the
nature of the claim shall have been served upon the Distributor or any such
person (or after the Distributor or the person shall have received notice of
service on any designated agent).  However, failure to notify the Fund of any
claim shall not relieve the Fund from any liability which it may have to the
Distributor or any person against whom such action is brought otherwise than on
account of its indemnity agreement contained in this paragraph.  The Fund shall
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 claims, but
if the Fund elects to assume the defense, the defense shall be conducted by
counsel chosen by it and satisfactory to the Distributor or person or persons,
defendant or defendants in the suit.  In the event the Fund elects to assume
the defense of any suit and retain counsel, the Distributor, officers or
trustees or controlling person or persons, defendant or defendants in the suit,
shall bear the fees and expenses of any additional counsel retained by them.
If the Fund does not elect to assume the defense of any suit, it will reimburse
the Distributor, officers or trustees or controlling person or persons,
defendant or defendants in the suit for the reasonable fees and expenses of any
counsel retained by them.  The Fund agrees to notify the Distributor promptly
of the commencement of any litigation or proceedings against it or any of its
officers or directors in connection with the issuance or sale of any of the
Shares.

     The Distributor also covenants and agrees that it will indemnify and hold
harmless the Fund and each of its trustees and officers and each person, if
any, who controls the Fund within the meaning of Section 15 of the 1933 Act     
against any loss, liability, damage, claim or expense (including the reasonable
cost of investigating or defending any alleged loss, liability, damage, claim
or expense and reasonable counsel fees incurred in connection therewith)
arising by reason of any person acquiring any Shares, based upon the 1933 Act
or any other statute or common law, alleging any wrongful act of the
Distributor or any of its employees or alleging that the registration
statement, Prospectus, shareholder reports or other information filed or made
public by the Fund (as from time to time amended) included an untrue statement
of a material fact or omitted to state a material fact required to be stated or
necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading, insofar as the
statement or omission was made in reliance upon, and in conformity with,
information furnished to the Fund by or on behalf of the Distributor.  In no
case (i) is the indemnity of the Distributor in favor of the Fund or any person
indemnified to be deemed to protect the Fund or any such person against any
liability to which the Fund or such person would otherwise be subject by reason
of willful misfeasance, bad faith or gross negligence in the performance of its
duties or by reason of its reckless disregard of its obligation and duties
under this Amended Agreement, or (ii) is the Distributor to be liable under its
indemnity agreement contained in this paragraph with respect to any claim made
against the Fund or any person indemnified unless the Fund or person, as the
case may be, shall have notified the Distributor in writing of the claim within
a reasonable time after the summons or other first 

                                      5

<PAGE>   34

written notification giving information of the nature of the claim shall have
been served upon the Fund or person (or after the Fund or such person shall
have received notice of service on any designated agent). However, failure to
notify the Distributor of any claim shall not relieve the Distributor from any
liability which it may have to the Fund or any person against whom the action
is brought otherwise than on account of its indemnity agreement contained in
this paragraph.  In the case of any notice to the Distributor, it shall 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 the claim, but if
the Distributor elects to assume the defense, the defense shall be conducted by
counsel chosen by it and satisfactory to the Fund, to its officers and trustees
and to any controlling person or persons, defendant or defendants in the suit. 
In the event that the Distributor elects to assume the defense of any suit and
retain counsel, the Fund or controlling persons, defendants in the suit, shall
bear the fees and expenses of any additional counsel retained by them.  If the
Distributor does not elect to assume the defense of any suit, it will reimburse
the Fund, officers and trustees or controlling person or persons, defendant or
defendants in the suit, for the reasonable fees and expenses of any counsel
retained by them.  The Distributor agrees to notify the Fund promptly of the
commencement of any litigation or proceedings against it in connection with the
issue and sale of any of the Shares.

     8.  Continuation, Amendment or Termination of This Agreement.  This
Agreement shall become effective on the Effective Date and thereafter shall
continue in full force and effect year to year with respect to each class of
Shares so long as such continuance is approved at least annually (i) by the
Board of Trustees of the Fund or by a vote of a majority of the outstanding
voting securities of the respective class of Shares of the Fund, and (ii) by
vote of a majority of the Trustees who are not parties to this Agreement or
interested persons in any such party (the "Independent Trustee") cast in person
at a meeting called for the purpose of voting on such approval, provided,
however, that (a) this Agreement may at any time be terminated with respect to
either class of Shares of the Fund without the payment of any penalty either by
vote of a majority of the Disinterested Trustees, or by vote of a majority of
the outstanding voting securities of the respective class of Shares of the
Fund, on written notice to the Distributor; (b) this Agreement shall
immediately terminate in the event of its assignment; and (c) this Agreement
may be terminated by the Distributor on ninety (90) days' written notice to the
Fund.  Upon termination of this Agreement with respect to either class of
Shares of the Fund, the obligations of the parties hereunder shall cease and
terminate with respect to such class of Shares as of the date of such
termination, except for any obligation to respond for a breach of this
Agreement committed prior to such termination.

     This Agreement may be amended with respect to either class of Shares at
any time by mutual consent of the parties, provided that such consent on the
part of the Fund shall have been approved (i) by the Board of Trustees of the
Fund, or by a vote of the majority of the outstanding voting securities of the
respective class of Shares of the Fund, and (ii) by vote of a majority of the
Independent Trustees cast in person at a meeting called for the purpose of
voting on such amendment.

     For the purpose of this section, the terms "vote of a majority of the
outstanding voting securities", "interested persons" and "assignment" shall
have the meanings defined in the 1940 Act, as amended.

     9.  Limited Liability of Shareholder.  Notwithstanding anything to the
contrary contained in this Agreement, you acknowledge and agree that, as
provided by Section 8.1 of the Agreement and Declaration of Trust of the Trust,
this Agreement is executed by the Trustees of the Trust and/or Officers of the
Fund by them not individually but as such Trustees and/or Officers, and the
obligations of the Fund hereunder are not binding upon any of the Trustees,
Officers or Shareholders individually, but bind only the trust estate.

     10.  Notice.  Any notice under this Agreement shall be given in writing,
addressed and delivered, or mailed postpaid, to the other party at any office
of such party or at such other address as such party shall have designated in
writing.

                                                          EXHIBIT (6)(a)(vi)


                       DISTRIBUTION AND SERVICE AGREEMENT


     THIS DISTRIBUTION AND SERVICE AGREEMENT dated as of October 31, 1996 (the
"Agreement") by and between VAN KAMPEN AMERICAN CAPITAL TAX FREE TRUST, a
Delaware business trust (the "Trust"), on behalf of its series, VAN KAMPEN
AMERICAN CAPITAL FLORIDA INSURED TAX FREE INCOME FUND (the "Fund"), and VAN
KAMPEN AMERICAN CAPITAL DISTRIBUTORS, INC., a Delaware corporation (the
"Distributor").

     1.  Appointment of Distributor.  The Fund appoints the Distributor as a
principal underwriter and exclusive distributor of each class of its shares of
beneficial interest (the "Shares") offered for sale from time to time pursuant
to the then current prospectus of the Fund, subject to different combinations
of front-end sales charges, distribution fees, service fees and contingent
deferred sales charges.  Classes of shares, if any, subject to a front-end
sales charge and a distribution and/or service fee are referred to herein as
"FESC Classes" and the Shares of such classes are referred to herein as "FESC
Shares."  Classes of shares, if any, subject to a contingent-deferred sales
charge and a distribution and/or a service fee are referred to herein as "CDSC
Classes" and Shares of such classes are referred to herein as "CDSC Shares."
Classes of shares, if any, subject to a front-end sales charge, a
contingent-deferred sales charge and a distribution and/or service fee are
referred to herein as "Combination Classes" and Shares of such class are
referred to herein as "Combination Shares."  The Fund reserves the right to
refuse at any time or times to sell Shares hereunder for any reason deemed
adequate by the Board of Trustees of the Fund.

     The Distributor will use its best efforts to sell, through its
organization and through other dealers and agents, the Shares which the
Distributor has the right to purchase under Section 2 hereof, but the
Distributor does not undertake to sell any specific number of Shares.

     The Distributor agrees that it will not take any long or short positions
in the Shares, except for long positions in those Shares purchased by the
Distributor in accordance with any systematic sales plan described in the then
current Prospectus of the Fund and except as permitted by Section 2 hereof, and
that so far as it can control the situation, it will prevent any of its
trustees, officers or shareholders from taking any long or short positions in
the Shares, except for legitimate investment purposes.

     2.  Sale of Shares to Distributor.  The Fund hereby grants to the
Distributor the exclusive right, except as herein otherwise provided, to
purchase Shares directly from the Fund upon the terms herein set forth.  Such
exclusive right hereby granted shall not apply to Shares issued or transferred
or sold at net asset value:  (a) in connection with the merger or consolidation
of the Fund with any other investment company or the acquisition by the Fund of
all or substantially all of the assets of or the outstanding Shares of any
investment company; (b) in connection with a pro rata distribution directly to
the holders of Fund Shares in the nature of a stock dividend or stock split or
in connection with any other recapitalization approved by the Board of
Trustees; (c) upon the exercise of purchase or subscription rights granted to
the holders of Shares on a pro rata basis; (d) in connection with the automatic
reinvestment of dividends and distributions from the Fund; or (e) in connection
with the issue and sale of Shares to trustees, officers and employees of the
Fund; to directors, officers and employees of the investment adviser of the
Fund or any principal underwriter (including the Distributor) of the Fund; to
retirees of the Distributor that purchased shares of any mutual fund
distributed by the Distributor prior to retirement; to directors, officers and
employees of Van Kampen American Capital, Inc. (formerly The Van Kampen Merritt
Companies, Inc.) (the parent of the Distributor), VK/AC Holding, Inc. (formerly
VKM Holdings, Inc.)(the parent of The Van Kampen Merritt Companies, Inc.) and
to the subsidiaries of VK/AC Holding, Inc.; and to any trust, pension,
profit-sharing or other benefit plan for any of the aforesaid persons as
permitted by Rule 22d-1 under the Investment Company Act of 1940 (the "1940
Act").

     The Distributor shall have the right to buy from the Fund the Shares
needed, but not more than the Shares needed (except for reasonable allowances
for clerical errors, delays and errors of 


                                      1
<PAGE>   37

transmission and cancellation of orders) to fill unconditional orders for
Shares received by the Distributor from dealers, agents and investors
during each period when particular net asset values and public offering prices
are in effect as provided in Section 3 hereof; and the price which the
Distributor shall pay for the Shares so purchased shall be the respective net
asset value used in determining the public offering price on which such orders
were based.  The Distributor shall notify the Fund at the end of each such
period, or as soon thereafter on that business day as the orders received in
such period have been compiled, of the number of Shares of each class that the
Distributor elects to purchase hereunder.

     3.  Public Offering Price.  The public offering price per Share shall be
determined in accordance with the then current Prospectus of the Fund.  In no
event shall the public offering price exceed the net asset value per Share,
plus, with respect to the FESC Shares,  a front-end sales charge not in excess
of the applicable maximum sales charge permitted under the Rules of Fair
Practice of the National Association of Securities Dealers, Inc., as in effect
from time to time.  The net asset value per share for each class of Shares,
respectively, shall be determined in the manner provided in the Declaration of
Trust and By-Laws of the Trust as then amended, the Certificate of Designation
with respect to the Fund, as amended, and in accordance with the then current
Prospectus of the Fund consistent with the terms and conditions of the
exemptive order with respect to the Fund (Release No. IC-19600) issued by the
Securities and Exchange Commission on July 28, 1993, as it may be amended from
time to time or succeeded by other exemptive orders or rules promulgated by the
Securities and Exchange Commission under the 1940 Act.  The Fund will cause
immediate notice to be given to the Distributor of each change in net asset
value as soon as it is determined.  Discounts to dealers purchasing FESC Shares
from the Distributor for resale and to brokers and other eligible agents making
sales of FESC Shares to investors and compensation payable from the Distributor
to dealers, brokers and other eligible agents making sales of CDSC Shares and
Combination Shares shall be set forth in the selling agreements between the
Distributor and such dealers or agents, respectively, as from time to time
amended, and, if such discounts and compensation are described in the then
current Prospectus for the Fund, shall be as so set forth.

     4.  Compliance with NASD Rules, SEC Orders, etc.  In selling Fund Shares,
the Distributor will in all respects duly comply with all state and federal
laws relating to the sale of such securities and with all applicable rules and
regulations of all regulatory bodies, including without limitation the Rules of
Fair Practice of the National Association of Securities Dealers, Inc., and all
applicable rules and regulations of the Securities and Exchange Commission
under the 1940 Act, and will indemnify and save the Fund harmless from any
damage or expense on account of any unlawful act by the Distributor or its
agents or employees.  The Distributor is not, however, to be responsible for
the acts of other dealers or agents, except to the extent that they shall be
acting for the Distributor or under its direction or authority.  None of the
Distributor, any dealer, any agent or any other person is authorized by the
Fund to give any information or to make any representations, other than those
contained in the Registration Statement or Prospectus heretofore or hereafter
filed with the Securities and Exchange Commission under the Securities Act of
1933, as amended (the "1933 Act") (as any such Registration Statement and
Prospectus may have been or may be amended from time to time), covering the
Shares, and in any supplemental information to any such Prospectus approved by
the Fund in connection with the offer or sale of Shares.  None of the
Distributor, any dealer, any broker or any other person is authorized to act as
agent for the Fund in connection with the offering or sale of Shares to the
public or otherwise.  All such sales shall be made by the Distributor as
principal for its own account.

     In selling Shares to investors, the Distributor will adopt and comply with
certain standards, as set forth in Exhibit III attached hereto as to when each
respective class of Shares may appropriately be sold to particular investors.
The Distributor will require every broker, dealer and other eligible agent
participating in the offering of the Shares to agree to adopt and comply with
such standards as a condition precedent to their participation in the offering.

     5.  Expenses.

             (a) The Fund will pay or cause to be paid:

             (i) all expenses in connection with the registration
                 of Shares under the federal securities laws, and the Fund will
                 exercise its best efforts to obtain said registration and
                 qualification;

            (ii) all expenses in connection with the printing of
                 any notices of shareholders' meetings, proxy and proxy
                 statements and enclosures therewith, as well as any other
                 notice or communication sent to shareholders in connection
                 with any meeting of the shareholders or otherwise, any annual,
                 semiannual or other reports or communications sent to the
                 shareholders, and the expenses of sending prospectuses
                 relating to the Shares to existing shareholders;

           (iii) all expenses of any federal or state
                 original-issue tax or transfer tax payable upon the issuance,
                 transfer or delivery of Shares from the Fund to the
                 Distributor; and

            (iv) the cost of preparing and issuing any Share
                 certificates which may be issued to represent Shares.

     (b)  The Distributor will pay the costs and expenses of qualifying and
maintaining qualification of the Shares for sale under the securities laws of
the various states.  The Distributor will also permit its officers and
employees to serve without compensation as trustees and officers of the Fund if
duly elected to such positions.

     (c)  The Fund shall reimburse the Distributor for out-of-pocket costs and
expenses actually incurred by it in connection with distribution of each class
of Shares respectively in accordance with the terms of a plan (the "12b-1
Plan") adopted by the Fund pursuant to Rule 12b-1 under the 1940 Act as such
12b-1 Plan may be in effect from time to time; provided, however, that no
payments shall be due or paid to the Distributor hereunder with respect to a
class of Shares unless and until this Agreement shall have been approved for
each such class by a majority of the Board of Trustees of the Fund and by a
majority of the "Disinterested Trustees" (as such term is defined in such 12b-1
Plan) by vote cast in person at a meeting called for the purpose of voting on
this Agreement.  A copy of such 12b-1 Plan as in effect on the date of this
Agreement is attached as Exhibit I hereto.  The Fund reserves the right to
terminate such 12b-1 Plan with respect to a class of Shares at any time, as
specified in the Plan.  The persons authorized to direct the payment of funds
pursuant to this Agreement and the 12b-1 Plan shall provide to the Fund's Board
of Trustees, and the Trustees shall review, at least quarterly, a written
report with respect to each of the classes of Shares of the amounts so paid and
the purposes for which such expenditures were made for each such class of
Shares.

     (d)  The Fund shall compensate the Distributor for providing services to,
and the maintenance of, shareholder accounts in the Fund (including prepaying
service fees to eligible brokers, dealers and financial intermediaries and
expenses incurred in connection therewith) and the Distributor may pay as agent
for and on behalf of the Fund a service fee with respect to each class of
Shares to brokers, dealers and financial intermediaries for the provision of
shareholder services and the maintenance of shareholder accounts in the Fund in
the amount with respect to each class of Shares set forth from time to time in
the Fund's prospectus.  The Fund shall compensate the Distributor for such
expenses in accordance with the terms of a service plan (the "Service Plan"),
as such Service Plan may be in effect from time to time; provided, however,
that no service fee payments shall be due or paid to the Distributor hereunder
with respect to a class of Shares unless and until this Agreement shall have
been approved for each such class by a majority of the Board of Trustees of the
Fund and by a majority of the Disinterested Trustees by vote cast in person at
a meeting called for the purpose of voting on this Agreement.  A copy of such
Service Plan as in effect on the date of this Agreement is attached as Exhibit
II hereto.  The Fund reserves the right to terminate such Service Plan with
respect to a class of Shares at any time, as specified in the Plan.  The
persons authorized to direct the payment of funds  


                                      3
<PAGE>   39
pursuant to this Agreement and the Service Plan shall provide to the Fund's
Board of Trustees, and the Trustees shall review, at least quarterly, a
written report with respect to each of the classes of Shares of the amounts
paid as service fees for each such class of Shares.

     6.  Redemption of Shares.  In connection with the Fund's redemption of its
Shares, the Fund hereby authorizes the Distributor to repurchase, upon the
terms and conditions hereinafter set forth, as the Fund's agent and for the
Fund's account, such Shares as may be offered for sale to the Fund from time to
time by holders of such Shares or their agents.

     (a)  Subject to and in conformity with all applicable federal and state
legislation, any applicable rules of the National Association of Securities
Dealers, Inc., and any applicable rules and regulations of the Securities and
Exchange Commission under the 1940 Act, the Distributor may accept offers of
holders of Shares to resell such Shares to the Fund on such terms and
conditions and at such prices as described and provided for in the then current
Prospectus of the Fund.

     (b)  The Distributor agrees to notify the Fund at such times as the Fund
may specify of the number of each class of Shares, respectively, repurchased
for the Fund's account and the time or times of such repurchases, and the Fund
shall notify the Distributor of the prices and, in the case of a class of CDSC
Shares or Combination Shares, of the deferred sales charge as described below,
if any, applicable to repurchases of Shares of such class.

     (c)  The Fund shall have the right to suspend or revoke the foregoing
authorization at any time; unless otherwise stated, any such suspension or
revocation shall be effective forthwith upon receipt of notice thereof by
telegraph or by written instrument from any of the Fund's officers.  In the
event that the Distributor's authorization is, by the terms of such notice,
suspended for more than twenty-four hours or until further notice, the
authorization given by this Section 6 shall not be revived except by vote of
the Board of Trustees of the Fund.

     (d)  The Distributor agrees that all repurchases of Shares made by the
Distributor shall be made only as agent for the Fund's account and pursuant to
the terms and conditions herein set forth.

     (e)  The Fund agrees to authorize and direct its Custodian to pay, for the
Fund's account, the repurchase price (together with any applicable contingent
deferred sales charge) of any Shares so repurchased for the Fund against the
authorized transfer of book shares from an open account and against delivery of
any other documentation required by the Board of Trustees of the Fund or, in
the case of certificated Shares, against delivery of the certificates
representing such Shares in proper form for transfer to the Fund.

     (f)  The Distributor shall receive no commissions or other compensation in
respect of any repurchases of FESC Shares for the Fund under the foregoing
authorization and appointment as agent.  With respect to any repurchase of CDSC
Shares or Combination Shares, the Distributor shall receive the deferred sales
charge, if any, applicable to the respective class of Shares that have been
held for less than a specified period of time with respect to such class as set
forth from time to time in the Fund's Prospectus.  The Distributor shall
receive no other commission or other compensation in respect of any repurchases
of CDSC Shares or Combination Shares for the Fund under the foregoing
authorization and appointment as agent.

     (g)  If any FESC Shares sold to the Distributor under the terms of this
Agreement are redeemed or repurchased by the Fund or by the Distributor as      
agent or are tendered for redemption within seven business days after the date
of the Distributor's confirmation of the original purchase by the Distributor,
the Distributor shall forfeit the amount above the net asset value received by
it in respect of such Shares, provided that the portion, if any, of such amount
re-allowed by the Distributor to dealers or agents shall be repayable to the
Fund only to the extent recovered by the Distributor from the dealer or agent
concerned.  The Distributor shall include in agreements with such dealers and
agents a corresponding provision for the forfeiture by them of their concession
with respect to FESC Shares purchased by them or their principals and redeemed
or repurchased by the Fund or by the Distributor as agent within seven business
days after the date of the Distributor's confirmation of such initial
purchases.

     7.  Indemnification.  The Fund agrees to indemnify and hold harmless the
Distributor and each of its trustees and officers and each person, if any, who
controls the Distributor within the meaning of Section 15 of the 1933 Act
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, based upon the ground
that the registration statement, Prospectus, shareholder reports or other
information filed or made public by the Fund (as from time to time amended)
included an untrue statement of a material fact or omitted to state a material
fact required to be stated or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading under the 1933 Act or any other statute or the common law.  However,
the Fund does not agree to indemnify the Distributor or hold it harmless to the
extent that the statement or omission was made in reliance upon, and in
conformity with, information furnished to the Fund by or on behalf of the
Distributor.  In no case (i) is the indemnity of the Fund in favor of the
Distributor or any person indemnified to be deemed to protect the Distributor
or any person against any liability to the Fund or its securityholders to which
the Distributor or such person would otherwise be subject by reason of willful
misfeasance, bad faith or gross negligence in the performance of its duties or
by reason of its 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 Section with respect to any claim made against the
Distributor or any person indemnified unless the Distributor or any such person
shall have notified the Fund in writing of the claim within a reasonable time
after the summons or other first written notification giving information of the
nature of the claim shall have been served upon the Distributor or any such
person (or after the Distributor or the person shall have received notice of
service on any designated agent).  However, failure to notify the Fund of any
claim shall not relieve the Fund from any liability which it may have to the
Distributor or any person against whom such action is brought otherwise than on
account of its indemnity agreement contained in this paragraph.  The Fund shall
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 claims, but
if the Fund elects to assume the defense, the defense shall be conducted by
counsel chosen by it and satisfactory to the Distributor or person or persons,
defendant or defendants in the suit.  In the event the Fund elects to assume
the defense of any suit and retain counsel, the Distributor, officers or
trustees or controlling person or persons, defendant or defendants in the suit,
shall bear the fees and expenses of any additional counsel retained by them.
If the Fund does not elect to assume the defense of any suit, it will reimburse
the Distributor, officers or trustees or controlling person or persons,
defendant or defendants in the suit for the reasonable fees and expenses of any
counsel retained by them.  The Fund agrees to notify the Distributor promptly
of the commencement of any litigation or proceedings against it or any of its
officers or directors in connection with the issuance or sale of any of the
Shares.

     The Distributor also covenants and agrees that it will indemnify and hold
harmless the Fund and each of its trustees and officers and each person, if     
any, who controls the Fund within the meaning of Section 15 of the 1933 Act
against any loss, liability, damage, claim or expense (including the reasonable
cost of investigating or defending any alleged loss, liability, damage, claim
or expense and reasonable counsel fees incurred in connection therewith)
arising by reason of any person acquiring any Shares, based upon the 1933 Act
or any other statute or common law, alleging any wrongful act of the
Distributor or any of its employees or alleging that the registration
statement, Prospectus, shareholder reports or other information filed or made
public by the Fund (as from time to time amended) included an untrue statement
of a material fact or omitted to state a material fact required to be stated or
necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading, insofar as the
statement or omission was made in reliance upon, and in conformity with,
information furnished to the Fund by or on behalf of the Distributor.  In no
case (i) is the indemnity of the Distributor in favor of the Fund or any person
indemnified to be deemed to protect the Fund or any such person against any
liability to which the Fund or such person would otherwise be subject by reason
of willful misfeasance, bad faith or gross negligence in the performance of its
duties or by reason of its reckless disregard of its obligation and duties
under this Amended Agreement, or (ii) is the Distributor to be liable under its
indemnity agreement contained in this paragraph with respect to any claim made
against the Fund or any person indemnified unless the Fund or person, as the
case may be, shall have notified the Distributor in writing of the claim within
a reasonable time after the summons or other first 


                                      5
<PAGE>   41

written notification giving information of the nature of
the claim shall have been served upon the Fund or person (or after the Fund or
such person shall have received notice of service on any designated agent).
However, failure to notify the Distributor of any claim shall not relieve the
Distributor from any liability which it may have to the Fund or any person
against whom the action is brought otherwise than on account of its indemnity
agreement contained in this paragraph.  In the case of any notice to the
Distributor, it shall 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 the claim, but if the Distributor elects to assume the defense, the
defense shall be conducted by counsel chosen by it and satisfactory to the
Fund, to its officers and trustees and to any controlling person or persons,
defendant or defendants in the suit.  In the event that the Distributor elects
to assume the defense of any suit and retain counsel, the Fund or controlling
persons, defendants in the suit, shall bear the fees and expenses of any
additional counsel retained by them.  If the Distributor does not elect to
assume the defense of any suit, it will reimburse the Fund, officers and
trustees or controlling person or persons, defendant or defendants in the suit,
for the reasonable fees and expenses of any counsel retained by them.  The
Distributor agrees to notify the Fund promptly of the commencement of any
litigation or proceedings against it in connection with the issue and sale of
any of the Shares.

     8.  Continuation, Amendment or Termination of This Agreement.  This
Agreement shall become effective on the Effective Date and thereafter shall
continue in full force and effect year to year with respect to each class of
Shares so long as such continuance is approved at least annually (i) by the
Board of Trustees of the Fund or by a vote of a majority of the outstanding
voting securities of the respective class of Shares of the Fund, and (ii) by
vote of a majority of the Trustees who are not parties to this Agreement or
interested persons in any such party (the "Independent Trustee") cast in person
at a meeting called for the purpose of voting on such approval, provided,
however, that (a) this Agreement may at any time be terminated with respect to
either class of Shares of the Fund without the payment of any penalty either by
vote of a majority of the Disinterested Trustees, or by vote of a majority of
the outstanding voting securities of the respective class of Shares of the
Fund, on written notice to the Distributor; (b) this Agreement shall
immediately terminate in the event of its assignment; and (c) this Agreement
may be terminated by the Distributor on ninety (90) days' written notice to the
Fund.  Upon termination of this Agreement with respect to either class of
Shares of the Fund, the obligations of the parties hereunder shall cease and
terminate with respect to such class of Shares as of the date of such
termination, except for any obligation to respond for a breach of this
Agreement committed prior to such termination.

     This Agreement may be amended with respect to either class of Shares at
any time by mutual consent of the parties, provided that such consent on the
part of the Fund shall have been approved (i) by the Board of Trustees of the
Fund, or by a vote of the majority of the outstanding voting securities of the
respective class of Shares of the Fund, and (ii) by vote of a majority of the
Independent Trustees cast in person at a meeting called for the purpose of
voting on such amendment.

     For the purpose of this section, the terms "vote of a majority of the
outstanding voting securities", "interested persons" and "assignment" shall
have the meanings defined in the 1940 Act, as amended.

     9.  Limited Liability of Shareholder.  Notwithstanding anything to the
contrary contained in this Agreement, you acknowledge and agree that, as
provided by Section 8.1 of the Agreement and Declaration of Trust of the Trust,
this Agreement is executed by the Trustees of the Trust and/or Officers of the
Fund by them not individually but as such Trustees and/or Officers, and the
obligations of the Fund hereunder are not binding upon any of the Trustees,
Officers or Shareholders individually, but bind only the trust estate.

     10.  Notice.  Any notice under this Agreement shall be given in writing,
addressed and delivered, or mailed postpaid, to the other party at any office
of such party or at such other address as such party shall have designated in
writing.

     11.  GOVERNING LAW.  THIS AGREEMENT SHALL BE CONSTRUED AND ENFORCED IN
ACCORDANCE WITH, AND THE RIGHTS OF THE PARTIES HERETO SHALL BE GOVERNED BY,

                                                           EXHIBIT (6) (a) (vii)


                       DISTRIBUTION AND SERVICE AGREEMENT


     THIS DISTRIBUTION AND SERVICE AGREEMENT dated as of October 31, 1996 (the
"Agreement") by and between VAN KAMPEN AMERICAN CAPITAL TAX FREE TRUST, a
Delaware business trust (the "Trust"), on behalf of its series, VAN KAMPEN
AMERICAN CAPITAL NEW JERSEY TAX FREE INCOME FUND (the "Fund"), and VAN KAMPEN
AMERICAN CAPITAL DISTRIBUTORS, INC., a Delaware corporation (the
"Distributor").

     1.  Appointment of Distributor.  The Fund appoints the Distributor as a
principal underwriter and exclusive distributor of each class of its shares of
beneficial interest (the "Shares") offered for sale from time to time pursuant
to the then current prospectus of the Fund, subject to different combinations
of front-end sales charges, distribution fees, service fees and contingent
deferred sales charges.  Classes of shares, if any, subject to a front-end
sales charge and a distribution and/or service fee are referred to herein as
"FESC Classes" and the Shares of such classes are referred to herein as "FESC
Shares."  Classes of shares, if any, subject to a contingent-deferred sales
charge and a distribution and/or a service fee are referred to herein as "CDSC
Classes" and Shares of such classes are referred to herein as "CDSC Shares."
Classes of shares, if any, subject to a front-end sales charge, a
contingent-deferred sales charge and a distribution and/or service fee are
referred to herein as "Combination Classes" and Shares of such class are
referred to herein as "Combination Shares."  The Fund reserves the right to
refuse at any time or times to sell Shares hereunder for any reason deemed
adequate by the Board of Trustees of the Fund.

     The Distributor will use its best efforts to sell, through its
organization and through other dealers and agents, the Shares which the
Distributor has the right to purchase under Section 2 hereof, but the
Distributor does not undertake to sell any specific number of Shares.

     The Distributor agrees that it will not take any long or short positions
in the Shares, except for long positions in those Shares purchased by the
Distributor in accordance with any systematic sales plan described in the then
current Prospectus of the Fund and except as permitted by Section 2 hereof, and
that so far as it can control the situation, it will prevent any of its
trustees, officers or shareholders from taking any long or short positions in
the Shares, except for legitimate investment purposes.

     2.  Sale of Shares to Distributor.  The Fund hereby grants to the
Distributor the exclusive right, except as herein otherwise provided, to
purchase Shares directly from the Fund upon the terms herein set forth.  Such
exclusive right hereby granted shall not apply to Shares issued or transferred
or sold at net asset value:  (a) in connection with the merger or consolidation
of the Fund with any other investment company or the acquisition by the Fund of
all or substantially all of the assets of or the outstanding Shares of any
investment company; (b) in connection with a pro rata distribution directly to
the holders of Fund Shares in the nature of a stock dividend or stock split or
in connection with any other recapitalization approved by the Board of
Trustees; (c) upon the exercise of purchase or subscription rights granted to
the holders of Shares on a pro rata basis; (d) in connection with the automatic
reinvestment of dividends and distributions from the Fund; or (e) in connection
with the issue and sale of Shares to trustees, officers and employees of the
Fund; to directors, officers and employees of the investment adviser of the
Fund or any principal underwriter (including the Distributor) of the Fund; to
retirees of the Distributor that purchased shares of any mutual fund
distributed by the Distributor prior to retirement; to directors, officers and
employees of Van Kampen American Capital, Inc. (formerly The Van Kampen Merritt
Companies, Inc.) (the parent of the Distributor), VK/AC Holding, Inc. (formerly
VKM Holdings, Inc.)(the parent of The Van Kampen Merritt Companies, Inc.) and
to the subsidiaries of VK/AC Holding, Inc.; and to any trust, pension,
profit-sharing or other benefit plan for any of the aforesaid persons as
permitted by Rule 22d-1 under the Investment Company Act of 1940 (the "1940
Act").

     The Distributor shall have the right to buy from the Fund the Shares
needed, but not more than the Shares needed (except for reasonable allowances
for clerical errors, delays and errors of 


                                      1
<PAGE>   44

transmission and cancellation of orders) to fill unconditional orders for
Shares received by the Distributor from dealers, agents and investors
during each period when particular net asset values and public offering prices
are in effect as provided in Section 3 hereof; and the price which the
Distributor shall pay for the Shares so purchased shall be the respective net
asset value used in determining the public offering price on which such orders
were based.  The Distributor shall notify the Fund at the end of each such
period, or as soon thereafter on that business day as the orders received in
such period have been compiled, of the number of Shares of each class that the
Distributor elects to purchase hereunder.

     3.  Public Offering Price.  The public offering price per Share shall be
determined in accordance with the then current Prospectus of the Fund.  In no
event shall the public offering price exceed the net asset value per Share,
plus, with respect to the FESC Shares,  a front-end sales charge not in excess
of the applicable maximum sales charge permitted under the Rules of Fair
Practice of the National Association of Securities Dealers, Inc., as in effect
from time to time.  The net asset value per share for each class of Shares,
respectively, shall be determined in the manner provided in the Declaration of
Trust and By-Laws of the Trust as then amended, the Certificate of Designation
with respect to the Fund, as amended, and in accordance with the then current
Prospectus of the Fund consistent with the terms and conditions of the
exemptive order with respect to the Fund (Release No. IC-19600) issued by the
Securities and Exchange Commission on July 28, 1993, as it may be amended from
time to time or succeeded by other exemptive orders or rules promulgated by the
Securities and Exchange Commission under the 1940 Act.  The Fund will cause
immediate notice to be given to the Distributor of each change in net asset
value as soon as it is determined.  Discounts to dealers purchasing FESC Shares
from the Distributor for resale and to brokers and other eligible agents making
sales of FESC Shares to investors and compensation payable from the Distributor
to dealers, brokers and other eligible agents making sales of CDSC Shares and
Combination Shares shall be set forth in the selling agreements between the
Distributor and such dealers or agents, respectively, as from time to time
amended, and, if such discounts and compensation are described in the then
current Prospectus for the Fund, shall be as so set forth.

     4.  Compliance with NASD Rules, SEC Orders, etc.  In selling Fund Shares,
the Distributor will in all respects duly comply with all state and federal
laws relating to the sale of such securities and with all applicable rules and
regulations of all regulatory bodies, including without limitation the Rules of
Fair Practice of the National Association of Securities Dealers, Inc., and all
applicable rules and regulations of the Securities and Exchange Commission
under the 1940 Act, and will indemnify and save the Fund harmless from any
damage or expense on account of any unlawful act by the Distributor or its
agents or employees.  The Distributor is not, however, to be responsible for
the acts of other dealers or agents, except to the extent that they shall be
acting for the Distributor or under its direction or authority.  None of the
Distributor, any dealer, any agent or any other person is authorized by the
Fund to give any information or to make any representations, other than those
contained in the Registration Statement or Prospectus heretofore or hereafter
filed with the Securities and Exchange Commission under the Securities Act of
1933, as amended (the "1933 Act") (as any such Registration Statement and
Prospectus may have been or may be amended from time to time), covering the
Shares, and in any supplemental information to any such Prospectus approved by
the Fund in connection with the offer or sale of Shares.  None of the
Distributor, any dealer, any broker or any other person is authorized to act as
agent for the Fund in connection with the offering or sale of Shares to the
public or otherwise.  All such sales shall be made by the Distributor as
principal for its own account.

     In selling Shares to investors, the Distributor will adopt and comply with
certain standards, as set forth in Exhibit III attached hereto as to when each
respective class of Shares may appropriately be sold to particular investors.
The Distributor will require every broker, dealer and other eligible agent
participating in the offering of the Shares to agree to adopt and comply with
such standards as a condition precedent to their participation in the offering.

     5.  Expenses.

             (a) The Fund will pay or cause to be paid:

             (i) all expenses in connection with the registration
                 of Shares under the federal securities laws, and the Fund will
                 exercise its best efforts to obtain said registration and
                 qualification;

            (ii) all expenses in connection with the printing of
                 any notices of shareholders' meetings, proxy and proxy
                 statements and enclosures therewith, as well as any other
                 notice or communication sent to shareholders in connection
                 with any meeting of the shareholders or otherwise, any annual,
                 semiannual or other reports or communications sent to the
                 shareholders, and the expenses of sending prospectuses
                 relating to the Shares to existing shareholders;

           (iii) all expenses of any federal or state original-issue tax or 
                 transfer tax payable upon the issuance, transfer or delivery 
                 of Shares from the Fund to the Distributor; and

            (iv) the cost of preparing and issuing any Share
                 certificates which may be issued to represent Shares.

           (b)  The Distributor will pay the costs and expenses of qualifying
and maintaining qualification of the Shares for sale under the securities laws
of the various states.  The Distributor will also permit its officers and
employees to serve without compensation as trustees and officers of the Fund if
duly elected to such positions.

           (c)  The Fund shall reimburse the Distributor for out-of-pocket costs
and expenses actually incurred by it in connection with distribution of each
class of Shares respectively in accordance with the terms of a plan (the "12b-1
Plan") adopted by the Fund pursuant to Rule 12b-1 under the 1940 Act as such
12b-1 Plan may be in effect from time to time; provided, however, that no
payments shall be due or paid to the Distributor hereunder with respect to a
class of Shares unless and until this Agreement shall have been approved for
each such class by a majority of the Board of Trustees of the Fund and by a
majority of the "Disinterested Trustees" (as such term is defined in such 12b-1
Plan) by vote cast in person at a meeting called for the purpose of voting on
this Agreement.  A copy of such 12b-1 Plan as in effect on the date of this
Agreement is attached as Exhibit I hereto.  The Fund reserves the right to
terminate such 12b-1 Plan with respect to a class of Shares at any time, as
specified in the Plan.  The persons authorized to direct the payment of funds
pursuant to this Agreement and the 12b-1 Plan shall provide to the Fund's Board
of Trustees, and the Trustees shall review, at least quarterly, a written report
with respect to each of the classes of Shares of the amounts so paid and the
purposes for which such expenditures were made for each such class of Shares.

           (d)  The Fund shall compensate the Distributor for providing services
to, and the maintenance of, shareholder accounts in the Fund (including
prepaying service fees to eligible brokers, dealers and financial intermediaries
and expenses incurred in connection therewith) and the Distributor may pay as
agent for and on behalf of the Fund a service fee with respect to each class of
Shares to brokers, dealers and financial intermediaries for the provision of
shareholder services and the maintenance of shareholder accounts in the Fund in
the amount with respect to each class of Shares set forth from time to time in
the Fund's prospectus.  The Fund shall compensate the Distributor for such
expenses in accordance with the terms of a service plan (the "Service Plan"), as
such Service Plan may be in effect from time to time; provided, however, that no
service fee payments shall be due or paid to the Distributor hereunder with
respect to a class of Shares unless and until this Agreement shall have been
approved for each such class by a majority of the Board of Trustees of the Fund
and by a majority of the Disinterested Trustees by vote cast in person at a
meeting called for the purpose of voting on this Agreement.  A copy of such
Service Plan as in effect on the date of this Agreement is attached as Exhibit
II hereto.  The Fund reserves the right to terminate such Service Plan with
respect to a class of Shares at any time, as specified in the Plan.  The persons
authorized to direct the payment of funds 



                                      3
<PAGE>   46

pursuant to this Agreement and the Service Plan shall provide to the
Fund's Board of Trustees, and the Trustees shall review, at least quarterly, a
written report with respect to each of the classes of Shares of the amounts
paid as service fees for each such class of Shares.

     6.  Redemption of Shares.  In connection with the Fund's redemption of its
Shares, the Fund hereby authorizes the Distributor to repurchase, upon the
terms and conditions hereinafter set forth, as the Fund's agent and for the
Fund's account, such Shares as may be offered for sale to the Fund from time to
time by holders of such Shares or their agents.

           (a)  Subject to and in conformity with all applicable federal and
state legislation, any applicable rules of the National Association of
Securities Dealers, Inc., and any applicable rules and regulations of the
Securities and Exchange Commission under the 1940 Act, the Distributor may
accept offers of holders of Shares to resell such Shares to the Fund on such
terms and conditions and at such prices as described and provided for in the
then current Prospectus of the Fund.

           (b)  The Distributor agrees to notify the Fund at such times as the
Fund may specify of the number of each class of Shares, respectively,
repurchased for the Fund's account and the time or times of such repurchases,
and the Fund shall notify the Distributor of the prices and, in the case of a
class of CDSC Shares or Combination Shares, of the deferred sales charge as
described below, if any, applicable to repurchases of Shares of such class.

           (c)  The Fund shall have the right to suspend or revoke the foregoing
authorization at any time; unless otherwise stated, any such suspension or
revocation shall be effective forthwith upon receipt of notice thereof by
telegraph or by written instrument from any of the Fund's officers.  In the
event that the Distributor's authorization is, by the terms of such notice,
suspended for more than twenty-four hours or until further notice, the
authorization given by this Section 6 shall not be revived except by vote of the
Board of Trustees of the Fund.

           (d)  The Distributor agrees that all repurchases of Shares made by
the Distributor shall be made only as agent for the Fund's account and pursuant
to the terms and conditions herein set forth.

           (e)  The Fund agrees to authorize and direct its Custodian to pay,
for the Fund's account, the repurchase price (together with any applicable
contingent deferred sales charge) of any Shares so repurchased for the Fund
against the authorized transfer of book shares from an open account and against
delivery of any other documentation required by the Board of Trustees of the
Fund or, in the case of certificated Shares, against delivery of the
certificates representing such Shares in proper form for transfer to the Fund.

           (f)  The Distributor shall receive no commissions or other
compensation in respect of any repurchases of FESC Shares for the Fund under the
foregoing authorization and appointment as agent.  With respect to any
repurchase of CDSC Shares or Combination Shares, the Distributor shall receive
the deferred sales charge, if any, applicable to the respective class of Shares
that have been held for less than a specified period of time with respect to
such class as set forth from time to time in the Fund's Prospectus.  The
Distributor shall receive no other commission or other compensation in respect
of any repurchases of CDSC Shares or Combination Shares for the Fund under the
foregoing authorization and appointment as agent.

           (g)  If any FESC Shares sold to the Distributor under the terms of
this Agreement are redeemed or repurchased by the Fund or by the Distributor as
agent or are tendered for redemption within seven business days after the date
of the Distributor's confirmation of the original purchase by the Distributor,
the Distributor shall forfeit the amount above the net asset value received by
it in respect of such Shares, provided that the portion, if any, of such amount
re-allowed by the Distributor to dealers or agents shall be repayable to the
Fund only to the extent recovered by the Distributor from the dealer or agent
concerned.  The Distributor shall include in agreements with such dealers and
agents a corresponding provision for the forfeiture by them of their concession
with respect to FESC Shares purchased by them or their principals and redeemed
or repurchased by the Fund or by the Distributor as agent within seven business
days after the date of the Distributor's confirmation of such initial purchases.

     7.  Indemnification.  The Fund agrees to indemnify and hold harmless the
Distributor and each of its trustees and officers and each person, if any, who
controls the Distributor within the meaning of Section 15 of the 1933 Act
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, based upon the ground
that the registration statement, Prospectus, shareholder reports or other
information filed or made public by the Fund (as from time to time amended)
included an untrue statement of a material fact or omitted to state a material
fact required to be stated or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading under the 1933 Act or any other statute or the common law.  However,
the Fund does not agree to indemnify the Distributor or hold it harmless to the
extent that the statement or omission was made in reliance upon, and in
conformity with, information furnished to the Fund by or on behalf of the
Distributor.  In no case (i) is the indemnity of the Fund in favor of the
Distributor or any person indemnified to be deemed to protect the Distributor
or any person against any liability to the Fund or its securityholders to which
the Distributor or such person would otherwise be subject by reason of willful
misfeasance, bad faith or gross negligence in the performance of its duties or
by reason of its 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 Section with respect to any claim made against the
Distributor or any person indemnified unless the Distributor or any such person
shall have notified the Fund in writing of the claim within a reasonable time
after the summons or other first written notification giving information of the
nature of the claim shall have been served upon the Distributor or any such
person (or after the Distributor or the person shall have received notice of
service on any designated agent).  However, failure to notify the Fund of any
claim shall not relieve the Fund from any liability which it may have to the
Distributor or any person against whom such action is brought otherwise than on
account of its indemnity agreement contained in this paragraph.  The Fund shall
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 claims, but
if the Fund elects to assume the defense, the defense shall be conducted by
counsel chosen by it and satisfactory to the Distributor or person or persons,
defendant or defendants in the suit.  In the event the Fund elects to assume
the defense of any suit and retain counsel, the Distributor, officers or
trustees or controlling person or persons, defendant or defendants in the suit,
shall bear the fees and expenses of any additional counsel retained by them.
If the Fund does not elect to assume the defense of any suit, it will reimburse
the Distributor, officers or trustees or controlling person or persons,
defendant or defendants in the suit for the reasonable fees and expenses of any
counsel retained by them.  The Fund agrees to notify the Distributor promptly
of the commencement of any litigation or proceedings against it or any of its
officers or directors in connection with the issuance or sale of any of the
Shares.

     The Distributor also covenants and agrees that it will indemnify and hold
harmless the Fund and each of its trustees and officers and each person, if
any, who controls the Fund within the meaning of Section 15 of the 1933 Act     
against any loss, liability, damage, claim or expense (including the reasonable
cost of investigating or defending any alleged loss, liability, damage, claim
or expense and reasonable counsel fees incurred in connection therewith)
arising by reason of any person acquiring any Shares, based upon the 1933 Act
or any other statute or common law, alleging any wrongful act of the
Distributor or any of its employees or alleging that the registration
statement, Prospectus, shareholder reports or other information filed or made
public by the Fund (as from time to time amended) included an untrue statement
of a material fact or omitted to state a material fact required to be stated or
necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading, insofar as the
statement or omission was made in reliance upon, and in conformity with,
information furnished to the Fund by or on behalf of the Distributor.  In no
case (i) is the indemnity of the Distributor in favor of the Fund or any person
indemnified to be deemed to protect the Fund or any such person against any
liability to which the Fund or such person would otherwise be subject by reason
of willful misfeasance, bad faith or gross negligence in the performance of its
duties or by reason of its reckless disregard of its obligation and duties
under this Amended Agreement, or (ii) is the Distributor to be liable under its
indemnity agreement contained in this paragraph with respect to any claim made
against the Fund or any person indemnified unless the Fund or person, as the
case may be, shall have notified the Distributor in writing of the claim within
a reasonable time after the summons or other first 


                                      5

<PAGE>   48

written notification giving information of the nature of the claim shall have
been served upon the Fund or person (or after the Fund or such person shall
have received notice of service on any designated agent). However, failure to
notify the Distributor of any claim shall not relieve the Distributor from any
liability which it may have to the Fund or any person against whom the action
is brought otherwise than on account of its indemnity agreement contained in
this paragraph.  In the case of any notice to the Distributor, it shall
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 the claim, but if
the Distributor elects to assume the defense, the defense shall be conducted by
counsel chosen by it and satisfactory to the Fund, to its officers and trustees
and to any controlling person or persons, defendant or defendants in the suit. 
In the event that the Distributor elects to assume the defense of any suit and
retain counsel, the Fund or controlling persons, defendants in the suit, shall
bear the fees and expenses of any additional counsel retained by them.  If the
Distributor does not elect to assume the defense of any suit, it will reimburse
the Fund, officers and trustees or controlling person or persons, defendant or
defendants in the suit, for the reasonable fees and expenses of any counsel
retained by them.  The Distributor agrees to notify the Fund promptly of the
commencement of any litigation or proceedings against it in connection with the
issue and sale of any of the Shares.

     8.  Continuation, Amendment or Termination of This Agreement.  This
Agreement shall become effective on the Effective Date and thereafter shall
continue in full force and effect year to year with respect to each class of
Shares so long as such continuance is approved at least annually (i) by the
Board of Trustees of the Fund or by a vote of a majority of the outstanding
voting securities of the respective class of Shares of the Fund, and (ii) by
vote of a majority of the Trustees who are not parties to this Agreement or
interested persons in any such party (the "Independent Trustee") cast in person
at a meeting called for the purpose of voting on such approval, provided,
however, that (a) this Agreement may at any time be terminated with respect to
either class of Shares of the Fund without the payment of any penalty either by
vote of a majority of the Disinterested Trustees, or by vote of a majority of
the outstanding voting securities of the respective class of Shares of the
Fund, on written notice to the Distributor; (b) this Agreement shall
immediately terminate in the event of its assignment; and (c) this Agreement
may be terminated by the Distributor on ninety (90) days' written notice to the
Fund.  Upon termination of this Agreement with respect to either class of
Shares of the Fund, the obligations of the parties hereunder shall cease and
terminate with respect to such class of Shares as of the date of such
termination, except for any obligation to respond for a breach of this
Agreement committed prior to such termination.

     This Agreement may be amended with respect to either class of Shares at
any time by mutual consent of the parties, provided that such consent on the
part of the Fund shall have been approved (i) by the Board of Trustees of the
Fund, or by a vote of the majority of the outstanding voting securities of the
respective class of Shares of the Fund, and (ii) by vote of a majority of the
Independent Trustees cast in person at a meeting called for the purpose of
voting on such amendment.

     For the purpose of this section, the terms "vote of a majority of the
outstanding voting securities", "interested persons" and "assignment" shall
have the meanings defined in the 1940 Act, as amended.

     9.  Limited Liability of Shareholder.  Notwithstanding anything to the
contrary contained in this Agreement, you acknowledge and agree that, as
provided by Section 8.1 of the Agreement and Declaration of Trust of the Trust,
this Agreement is executed by the Trustees of the Trust and/or Officers of the
Fund by them not individually but as such Trustees and/or Officers, and the
obligations of the Fund hereunder are not binding upon any of the Trustees,
Officers or Shareholders individually, but bind only the trust estate.

     10.  Notice.  Any notice under this Agreement shall be given in writing,
addressed and delivered, or mailed postpaid, to the other party at any office
of such party or at such other address as such party shall have designated in
writing.

     11.  GOVERNING LAW.  THIS AGREEMENT SHALL BE CONSTRUED AND ENFORCED IN
ACCORDANCE WITH, AND THE RIGHTS OF THE PARTIES HERETO SHALL BE GOVERNED BY,

                                                           EXHIBIT (6)(a)(viii)


                       DISTRIBUTION AND SERVICE AGREEMENT


     THIS DISTRIBUTION AND SERVICE AGREEMENT dated as of October 31, 1996 (the
"Agreement") by and between VAN KAMPEN AMERICAN CAPITAL TAX FREE TRUST, a
Delaware business trust (the "Trust"), on behalf of its series, VAN KAMPEN
AMERICAN CAPITAL NEW YORK TAX FREE INCOME FUND (the "Fund"), and VAN KAMPEN
AMERICAN CAPITAL DISTRIBUTORS, INC., a Delaware corporation (the
"Distributor").

     1.  Appointment of Distributor.  The Fund appoints the Distributor as a
principal underwriter and exclusive distributor of each class of its shares of
beneficial interest (the "Shares") offered for sale from time to time pursuant
to the then current prospectus of the Fund, subject to different combinations
of front-end sales charges, distribution fees, service fees and contingent
deferred sales charges.  Classes of shares, if any, subject to a front-end
sales charge and a distribution and/or service fee are referred to herein as
"FESC Classes" and the Shares of such classes are referred to herein as "FESC
Shares."  Classes of shares, if any, subject to a contingent-deferred sales
charge and a distribution and/or a service fee are referred to herein as "CDSC
Classes" and Shares of such classes are referred to herein as "CDSC Shares."
Classes of shares, if any, subject to a front-end sales charge, a
contingent-deferred sales charge and a distribution and/or service fee are
referred to herein as "Combination Classes" and Shares of such class are
referred to herein as "Combination Shares."  The Fund reserves the right to
refuse at any time or times to sell Shares hereunder for any reason deemed
adequate by the Board of Trustees of the Fund.

     The Distributor will use its best efforts to sell, through its
organization and through other dealers and agents, the Shares which the
Distributor has the right to purchase under Section 2 hereof, but the
Distributor does not undertake to sell any specific number of Shares.

     The Distributor agrees that it will not take any long or short positions
in the Shares, except for long positions in those Shares purchased by the
Distributor in accordance with any systematic sales plan described in the then
current Prospectus of the Fund and except as permitted by Section 2 hereof, and
that so far as it can control the situation, it will prevent any of its
trustees, officers or shareholders from taking any long or short positions in
the Shares, except for legitimate investment purposes.

     2.  Sale of Shares to Distributor.  The Fund hereby grants to the
Distributor the exclusive right, except as herein otherwise provided, to
purchase Shares directly from the Fund upon the terms herein set forth.  Such
exclusive right hereby granted shall not apply to Shares issued or transferred
or sold at net asset value:  (a) in connection with the merger or consolidation
of the Fund with any other investment company or the acquisition by the Fund of
all or substantially all of the assets of or the outstanding Shares of any
investment company; (b) in connection with a pro rata distribution directly to
the holders of Fund Shares in the nature of a stock dividend or stock split or
in connection with any other recapitalization approved by the Board of
Trustees; (c) upon the exercise of purchase or subscription rights granted to
the holders of Shares on a pro rata basis; (d) in connection with the automatic
reinvestment of dividends and distributions from the Fund; or (e) in connection
with the issue and sale of Shares to trustees, officers and employees of the
Fund; to directors, officers and employees of the investment adviser of the
Fund or any principal underwriter (including the Distributor) of the Fund; to
retirees of the Distributor that purchased shares of any mutual fund
distributed by the Distributor prior to retirement; to directors, officers and
employees of Van Kampen American Capital, Inc. (formerly The Van Kampen Merritt
Companies, Inc.) (the parent of the Distributor), VK/AC Holding, Inc. (formerly
VKM Holdings, Inc.)(the parent of The Van Kampen Merritt Companies, Inc.) and
to the subsidiaries of VK/AC Holding, Inc.; and to any trust, pension,
profit-sharing or other benefit plan for any of the aforesaid persons as
permitted by Rule 22d-1 under the Investment Company Act of 1940 (the "1940
Act").

     The Distributor shall have the right to buy from the Fund the Shares
needed, but not more than the Shares needed (except for reasonable allowances
for clerical errors, delays and errors of 


                                      1
<PAGE>   51
transmission and cancellation of orders) to fill unconditional orders for
Shares received by the Distributor from dealers, agents and investors during
each period when particular net asset values and public offering prices are in
effect as provided in Section 3 hereof; and the price which the Distributor
shall pay for the Shares so purchased shall be the respective net asset value
used in determining the public offering price on which such orders were based. 
The Distributor shall notify the Fund at the end of each such period, or as
soon thereafter on that business day as the orders received in such period have
been compiled, of the number of Shares of each class that the Distributor
elects to purchase hereunder.

     3.  Public Offering Price.  The public offering price per Share shall be
determined in accordance with the then current Prospectus of the Fund.  In no
event shall the public offering price exceed the net asset value per Share,
plus, with respect to the FESC Shares,  a front-end sales charge not in excess
of the applicable maximum sales charge permitted under the Rules of Fair
Practice of the National Association of Securities Dealers, Inc., as in effect
from time to time.  The net asset value per share for each class of Shares,
respectively, shall be determined in the manner provided in the Declaration of
Trust and By-Laws of the Trust as then amended, the Certificate of Designation
with respect to the Fund, as amended, and in accordance with the then current
Prospectus of the Fund consistent with the terms and conditions of the
exemptive order with respect to the Fund (Release No. IC-19600) issued by the
Securities and Exchange Commission on July 28, 1993, as it may be amended from
time to time or succeeded by other exemptive orders or rules promulgated by the
Securities and Exchange Commission under the 1940 Act.  The Fund will cause
immediate notice to be given to the Distributor of each change in net asset
value as soon as it is determined.  Discounts to dealers purchasing FESC Shares
from the Distributor for resale and to brokers and other eligible agents making
sales of FESC Shares to investors and compensation payable from the Distributor
to dealers, brokers and other eligible agents making sales of CDSC Shares and
Combination Shares shall be set forth in the selling agreements between the
Distributor and such dealers or agents, respectively, as from time to time
amended, and, if such discounts and compensation are described in the then
current Prospectus for the Fund, shall be as so set forth.

     4.  Compliance with NASD Rules, SEC Orders, etc.  In selling Fund Shares,
the Distributor will in all respects duly comply with all state and federal
laws relating to the sale of such securities and with all applicable rules and
regulations of all regulatory bodies, including without limitation the Rules of
Fair Practice of the National Association of Securities Dealers, Inc., and all
applicable rules and regulations of the Securities and Exchange Commission
under the 1940 Act, and will indemnify and save the Fund harmless from any
damage or expense on account of any unlawful act by the Distributor or its
agents or employees.  The Distributor is not, however, to be responsible for
the acts of other dealers or agents, except to the extent that they shall be
acting for the Distributor or under its direction or authority.  None of the
Distributor, any dealer, any agent or any other person is authorized by the
Fund to give any information or to make any representations, other than those
contained in the Registration Statement or Prospectus heretofore or hereafter
filed with the Securities and Exchange Commission under the Securities Act of
1933, as amended (the "1933 Act") (as any such Registration Statement and
Prospectus may have been or may be amended from time to time), covering the
Shares, and in any supplemental information to any such Prospectus approved by
the Fund in connection with the offer or sale of Shares.  None of the
Distributor, any dealer, any broker or any other person is authorized to act as
agent for the Fund in connection with the offering or sale of Shares to the
public or otherwise.  All such sales shall be made by the Distributor as
principal for its own account.

     In selling Shares to investors, the Distributor will adopt and comply with
certain standards, as set forth in Exhibit III attached hereto as to when each
respective class of Shares may appropriately be sold to particular investors.
The Distributor will require every broker, dealer and other eligible agent
participating in the offering of the Shares to agree to adopt and comply with
such standards as a condition precedent to their participation in the offering.

     5.  Expenses.

     (a)  The Fund will pay or cause to be paid:

          (i)    all expenses in connection with the registration
                 of Shares under the federal securities laws, and the Fund will
                 exercise its best efforts to obtain said registration and
                 qualification;

         (ii)    all expenses in connection with the printing of
                 any notices of shareholders' meetings, proxy and proxy
                 statements and enclosures therewith, as well as any other
                 notice or communication sent to shareholders in connection
                 with any meeting of the shareholders or otherwise, any annual,
                 semiannual or other reports or communications sent to the
                 shareholders, and the expenses of sending prospectuses
                 relating to the Shares to existing shareholders;

        (iii)    all expenses of any federal or state
                 original-issue tax or transfer tax payable upon the issuance,
                 transfer or delivery of Shares from the Fund to the
                 Distributor; and

         (iv)    the cost of preparing and issuing any Share
                 certificates which may be issued to represent Shares.

     (b)  The Distributor will pay the costs and expenses of qualifying and
maintaining qualification of the Shares for sale under the securities laws of
the various states.  The Distributor will also permit its officers and
employees to serve without compensation as trustees and officers of the Fund if
duly elected to such positions.

     (c)  The Fund shall reimburse the Distributor for out-of-pocket costs and
expenses actually incurred by it in connection with distribution of each class
of Shares respectively in accordance with the terms of a plan (the "12b-1
Plan") adopted by the Fund pursuant to Rule 12b-1 under the 1940 Act as such
12b-1 Plan may be in effect from time to time; provided, however, that no
payments shall be due or paid to the Distributor hereunder with respect to a
class of Shares unless and until this Agreement shall have been approved for
each such class by a majority of the Board of Trustees of the Fund and by a
majority of the "Disinterested Trustees" (as such term is defined in such 12b-1
Plan) by vote cast in person at a meeting called for the purpose of voting on
this Agreement.  A copy of such 12b-1 Plan as in effect on the date of this
Agreement is attached as Exhibit I hereto.  The Fund reserves the right to
terminate such 12b-1 Plan with respect to a class of Shares at any time, as
specified in the Plan.  The persons authorized to direct the payment of funds
pursuant to this Agreement and the 12b-1 Plan shall provide to the Fund's Board
of Trustees, and the Trustees shall review, at least quarterly, a written
report with respect to each of the classes of Shares of the amounts so paid and
the purposes for which such expenditures were made for each such class of
Shares.

     (d)  The Fund shall compensate the Distributor for providing services to,
and the maintenance of, shareholder accounts in the Fund (including prepaying
service fees to eligible brokers, dealers and financial intermediaries and
expenses incurred in connection therewith) and the Distributor may pay as agent
for and on behalf of the Fund a service fee with respect to each class of
Shares to brokers, dealers and financial intermediaries for the provision of
shareholder services and the maintenance of shareholder accounts in the Fund in
the amount with respect to each class of Shares set forth from time to time in
the Fund's prospectus.  The Fund shall compensate the Distributor for such
expenses in accordance with the terms of a service plan (the "Service Plan"),
as such Service Plan may be in effect from time to time; provided, however,
that no service fee payments shall be due or paid to the Distributor hereunder
with respect to a class of Shares unless and until this Agreement shall have
been approved for each such class by a majority of the Board of Trustees of the
Fund and by a majority of the Disinterested Trustees by vote cast in person at
a meeting called for the purpose of voting on this Agreement.  A copy of such
Service Plan as in effect on the date of this Agreement is attached as Exhibit
II hereto.  The Fund reserves the right to terminate such Service Plan with
respect to a class of Shares at any time, as specified in the Plan.  The
persons authorized to direct the payment of funds 


                                      3
<PAGE>   53
pursuant to this Agreement and the Service Plan shall provide to the Fund's
Board of Trustees, and the Trustees shall review, at least quarterly, a
written report with respect to each of the classes of Shares of the amounts
paid as service fees for each such class of Shares.

     6.  Redemption of Shares.  In connection with the Fund's redemption of its
Shares, the Fund hereby authorizes the Distributor to repurchase, upon the
terms and conditions hereinafter set forth, as the Fund's agent and for the
Fund's account, such Shares as may be offered for sale to the Fund from time to
time by holders of such Shares or their agents.

     (a)  Subject to and in conformity with all applicable federal and state
legislation, any applicable rules of the National Association of Securities
Dealers, Inc., and any applicable rules and regulations of the Securities and
Exchange Commission under the 1940 Act, the Distributor may accept offers of
holders of Shares to resell such Shares to the Fund on such terms and
conditions and at such prices as described and provided for in the then current
Prospectus of the Fund.

     (b)  The Distributor agrees to notify the Fund at such times as the Fund
may specify of the number of each class of Shares, respectively, repurchased
for the Fund's account and the time or times of such repurchases, and the Fund
shall notify the Distributor of the prices and, in the case of a class of CDSC
Shares or Combination Shares, of the deferred sales charge as described below,
if any, applicable to repurchases of Shares of such class.

     (c)  The Fund shall have the right to suspend or revoke the foregoing
authorization at any time; unless otherwise stated, any such suspension or
revocation shall be effective forthwith upon receipt of notice thereof by
telegraph or by written instrument from any of the Fund's officers.  In the
event that the Distributor's authorization is, by the terms of such notice,
suspended for more than twenty-four hours or until further notice, the
authorization given by this Section 6 shall not be revived except by vote of
the Board of Trustees of the Fund.

     (d)  The Distributor agrees that all repurchases of Shares made by the
Distributor shall be made only as agent for the Fund's account and pursuant to
the terms and conditions herein set forth.

     (e)  The Fund agrees to authorize and direct its Custodian to pay, for the
Fund's account, the repurchase price (together with any applicable contingent
deferred sales charge) of any Shares so repurchased for the Fund against the
authorized transfer of book shares from an open account and against delivery of
any other documentation required by the Board of Trustees of the Fund or, in
the case of certificated Shares, against delivery of the certificates
representing such Shares in proper form for transfer to the Fund.

     (f)  The Distributor shall receive no commissions or other compensation in
respect of any repurchases of FESC Shares for the Fund under the foregoing
authorization and appointment as agent.  With respect to any repurchase of CDSC
Shares or Combination Shares, the Distributor shall receive the deferred sales
charge, if any, applicable to the respective class of Shares that have been
held for less than a specified period of time with respect to such class as set
forth from time to time in the Fund's Prospectus.  The Distributor shall
receive no other commission or other compensation in respect of any repurchases
of CDSC Shares or Combination Shares for the Fund under the foregoing
authorization and appointment as agent.

     (g)  If any FESC Shares sold to the Distributor under the terms of this
Agreement are redeemed or repurchased by the Fund or by the Distributor as
agent or are tendered for redemption within seven business days after the date
of the Distributor's confirmation of the original purchase by the Distributor,
the Distributor shall forfeit the amount above the net asset value received by
it in respect of such Shares, provided that the portion, if any, of such amount
re-allowed by the Distributor to dealers or agents shall be repayable to the
Fund only to the extent recovered by the Distributor from the dealer or agent
concerned.  The Distributor shall include in agreements with such dealers and
agents a corresponding provision for the forfeiture by them of their
concession with respect to FESC Shares purchased by them or their principals
and redeemed or repurchased by the Fund or by the Distributor as agent within
seven business days after the date of the Distributor's confirmation of such
initial purchases.

     7.  Indemnification.  The Fund agrees to indemnify and hold harmless the
Distributor and each of its trustees and officers and each person, if any, who
controls the Distributor within the meaning of Section 15 of the 1933 Act
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, based upon the ground
that the registration statement, Prospectus, shareholder reports or other
information filed or made public by the Fund (as from time to time amended)
included an untrue statement of a material fact or omitted to state a material
fact required to be stated or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading under the 1933 Act or any other statute or the common law.  However,
the Fund does not agree to indemnify the Distributor or hold it harmless to the
extent that the statement or omission was made in reliance upon, and in
conformity with, information furnished to the Fund by or on behalf of the
Distributor.  In no case (i) is the indemnity of the Fund in favor of the
Distributor or any person indemnified to be deemed to protect the Distributor
or any person against any liability to the Fund or its securityholders to which
the Distributor or such person would otherwise be subject by reason of willful
misfeasance, bad faith or gross negligence in the performance of its duties or
by reason of its 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 Section with respect to any claim made against the
Distributor or any person indemnified unless the Distributor or any such person
shall have notified the Fund in writing of the claim within a reasonable time
after the summons or other first written notification giving information of the
nature of the claim shall have been served upon the Distributor or any such
person (or after the Distributor or the person shall have received notice of
service on any designated agent).  However, failure to notify the Fund of any
claim shall not relieve the Fund from any liability which it may have to the
Distributor or any person against whom such action is brought otherwise than on
account of its indemnity agreement contained in this paragraph.  The Fund shall
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 claims, but
if the Fund elects to assume the defense, the defense shall be conducted by
counsel chosen by it and satisfactory to the Distributor or person or persons,
defendant or defendants in the suit.  In the event the Fund elects to assume
the defense of any suit and retain counsel, the Distributor, officers or
trustees or controlling person or persons, defendant or defendants in the suit,
shall bear the fees and expenses of any additional counsel retained by them.
If the Fund does not elect to assume the defense of any suit, it will reimburse
the Distributor, officers or trustees or controlling person or persons,
defendant or defendants in the suit for the reasonable fees and expenses of any
counsel retained by them.  The Fund agrees to notify the Distributor promptly
of the commencement of any litigation or proceedings against it or any of its
officers or directors in connection with the issuance or sale of any of the
Shares.

     The Distributor also covenants and agrees that it will indemnify and hold
harmless the Fund and each of its trustees and officers and each person, if
any, who controls the Fund within the meaning of Section 15 of the 1933 Act
against any loss, liability, damage, claim or expense (including the reasonable
cost of investigating or defending any alleged loss, liability, damage, claim
or expense and reasonable counsel fees incurred in connection therewith)
arising by reason of any person acquiring any Shares, based upon the 1933 Act
or any other statute or common law, alleging any wrongful act of the
Distributor or any of its employees or alleging that the registration
statement, Prospectus, shareholder reports or other information filed or made
public by the Fund (as from time to time amended) included an untrue statement
of a material fact or omitted to state a material fact required to be stated or
necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading, insofar as the
statement or omission was made in reliance upon, and in conformity with,
information furnished to the Fund by or on behalf of the Distributor.  In no
case (i) is the indemnity of the Distributor in favor of the Fund or any person
indemnified to be deemed to protect the Fund or any such person against any
liability to which the Fund or such person would otherwise be subject by reason
of willful misfeasance, bad faith or gross negligence in the performance of its
duties or by reason of its reckless disregard of its obligation and duties
under this Amended Agreement, or (ii) is the Distributor to be liable under its
indemnity agreement contained in this paragraph with respect to any claim made
against the Fund or any person indemnified unless the Fund or person, as the
case may be, shall have notified the Distributor in writing of the claim within
a reasonable time after the summons or other first 


                                      5
<PAGE>   55
written notification giving information of the nature of the claim shall have
been served upon the Fund or person (or after the Fund or such person shall
have received notice of service on any designated agent). However, failure to
notify the Distributor of any claim shall not relieve the Distributor from any
liability which it may have to the Fund or any person against whom the action
is brought otherwise than on account of its indemnity agreement contained in
this paragraph.  In the case of any notice to the Distributor, it shall 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 the claim, but if
the Distributor elects to assume the defense, the defense shall be conducted by
counsel chosen by it and satisfactory to the Fund, to its officers and trustees
and to any controlling person or persons, defendant or defendants in the suit. 
In the event that the Distributor elects to assume the defense of any suit and
retain counsel, the Fund or controlling persons, defendants in the suit, shall
bear the fees and expenses of any additional counsel retained by them.  If the
Distributor does not elect to assume the defense of any suit, it will reimburse
the Fund, officers and trustees or controlling person or persons, defendant or
defendants in the suit, for the reasonable fees and expenses of any counsel
retained by them.  The Distributor agrees to notify the Fund promptly of the
commencement of any litigation or proceedings against it in connection with the
issue and sale of any of the Shares.

     8.  Continuation, Amendment or Termination of This Agreement.  This
Agreement shall become effective on the Effective Date and thereafter shall
continue in full force and effect year to year with respect to each class of
Shares so long as such continuance is approved at least annually (i) by the
Board of Trustees of the Fund or by a vote of a majority of the outstanding
voting securities of the respective class of Shares of the Fund, and (ii) by
vote of a majority of the Trustees who are not parties to this Agreement or
interested persons in any such party (the "Independent Trustee") cast in person
at a meeting called for the purpose of voting on such approval, provided,
however, that (a) this Agreement may at any time be terminated with respect to
either class of Shares of the Fund without the payment of any penalty either by
vote of a majority of the Disinterested Trustees, or by vote of a majority of
the outstanding voting securities of the respective class of Shares of the
Fund, on written notice to the Distributor; (b) this Agreement shall
immediately terminate in the event of its assignment; and (c) this Agreement
may be terminated by the Distributor on ninety (90) days' written notice to the
Fund.  Upon termination of this Agreement with respect to either class of
Shares of the Fund, the obligations of the parties hereunder shall cease and
terminate with respect to such class of Shares as of the date of such
termination, except for any obligation to respond for a breach of this
Agreement committed prior to such termination.

     This Agreement may be amended with respect to either class of Shares at
any time by mutual consent of the parties, provided that such consent on the
part of the Fund shall have been approved (i) by the Board of Trustees of the
Fund, or by a vote of the majority of the outstanding voting securities of the
respective class of Shares of the Fund, and (ii) by vote of a majority of the
Independent Trustees cast in person at a meeting called for the purpose of
voting on such amendment.

     For the purpose of this section, the terms "vote of a majority of the
outstanding voting securities", "interested persons" and "assignment" shall
have the meanings defined in the 1940 Act, as amended.

     9.  Limited Liability of Shareholder.  Notwithstanding anything to the
contrary contained in this Agreement, you acknowledge and agree that, as
provided by Section 8.1 of the Agreement and Declaration of Trust of the Trust,
this Agreement is executed by the Trustees of the Trust and/or Officers of the
Fund by them not individually but as such Trustees and/or Officers, and the
obligations of the Fund hereunder are not binding upon any of the Trustees,
Officers or Shareholders individually, but bind only the trust estate.

     10.  Notice.  Any notice under this Agreement shall be given in writing,
addressed and delivered, or mailed postpaid, to the other party at any office
of such party or at such other address as such party shall have designated in
writing.

     11.  GOVERNING LAW.  THIS AGREEMENT SHALL BE CONSTRUED AND ENFORCED IN
ACCORDANCE WITH, AND THE RIGHTS OF THE PARTIES HERETO SHALL BE GOVERNED BY,

                   Registration Statement on Form N-1A
                   (File Nos. 2-99715 and 811-4386)          
    
                                                                   

   
Ladies and Gentlemen:
        We have acted as counsel to Van Kampen American Capital Tax Free Trust
(the "Trust"), a Delaware business trust, on behalf of each series of the Trust
listed on Annex A hereto (the "Funds") in connection with the preparation of
Post-Effective Amendment No. 40 to the Trust's Registration Statement on Form 
N-1A (the "Registration Statement") to be filed under the Securities Act of
1933, as amended (the "1933 Act"), and the Investment Company Act of 1940, as
amended (the "1940 Act"), with the Securities and Exchange Commission (the
"Commission") on or about April 29, 1997. The Registration Statement relates to
the registration under the 1933 Act and 1940 Act of an indefinite number of
each of Class A Shares of beneficial interest, par value $.01 per share, Class
B Shares of beneficial interest, par value $.01 per share, and Class C Shares
of beneficial interest, par value $.01 per share, of each of the Funds
(collectively, the "Shares").
    
        
        This opinion is delivered in accordance with the requirements of Item
24(b)(10) of Form N-1A under the 1933 Act and the 1940 Act.

        In connection with this opinion, we have examined the originals or
copies, certified or otherwise identified to our satisfaction, of (i) the
Certificate of Trust filed with the Secretary of State of Delaware, (ii)

the Agreement and Declaration of Trust and By-Laws of the Trust, each as
amended to date (the "Declaration of Trust" and "By-Laws", respectively), (iii)
the Certificate of Designation establishing each of the Funds,  (iv) the
resolutions adopted by the Board of Trustees of the Trust relating to the
authorization, issuance and sale of the Shares, the filing of the Registration
Statement and any amendments or supplements thereto and related matters and (v)
such other documents as we have deemed necessary or appropriate as a basis for
the opinions set forth herein.
    

        In such examination we have assumed the legal capacity of natural
persons, the genuineness of all signatures, the authenticity of all documents
submitted to us as originals, the conformity to original documents of all
documents submitted to us as certified, conformed, photostatic, or other copies
and the authenticity of the originals of such latter documents.  As to any
facts material to such opinion which were not independently established, we
have relied on statements or representations of officers and other
representatives of the Trust or others.

        Members of our firm are admitted to the practice of law in the State
of Illinois, and we do not express any opinion as to the laws of any other
jurisdiction other than matters relating to the Delaware business
organizational statutes (including statutes relating to Delaware business
trusts) and the federal laws of the United States of America to the extent
specifically referred to herein.

        Based upon and subject to the foregoing, we are of the opinion that the
issuance and sale of Shares by the Trust have been validly authorized and,
assuming certificates therefor have been duly executed, countersigned,
registered and delivered or the shareholders' accounts have been duly credited
and the Shares represented thereby have been fully paid for, such Shares will
be validly issued, fully paid and nonassessable.

        We hereby consent to the filing of this opinion with the Commission as
Exhibit 10 to the Registration Statement.  We also consent to the reference to
our firm under the heading "Legal Counsel" in the Registration Statement.  In
giving this consent, we do not hereby admit that we are in the category of
persons whose consent is required under Section 7 of the 1933 Act or the rules
and regulations of the Commission.
        
                           Very truly yours,

                              CALCULATION OF YIELD
 
  The Fund calculates its yield quotations based on a 30-day period ended on the
date of the most recent balance sheet included in the registration statement, by
dividing the net investment income per share earned during the period by the
maximum offering price per share on the last day of the period, according to the
following formula:
                                       a - b    6
                      YIELD (y) = 2 [( ----- +1) -1]
                                        cd
 
Where:  a  = dividends and interest earned during the period
 
        b  = expenses accrued for the period (net of reimbursements)
 
        c  = the average daily number of shares outstanding during the period
             that were entitled to receive dividends
 
        d  = the maximum offering price per share on the last day of the period

                              CALCULATION OF YIELD
 
  The Fund calculates its yield quotations based on a 30-day period ended on the
date of the most recent balance sheet included in the registration statement, by
dividing the net investment income per share earned during the period by the
maximum offering price per share on the last day of the period, according to the
following formula:
 
                                      a-b      6
                      YIELD (y) = 2[(----- + 1) -1]
                                       cd
 
Where: a = dividends and interest earned during the period
 
       b = expenses accrued for the period (net of reimbursements)
 
       c = the average daily number of shares outstanding during the period that
           were entitled to receive dividends
 
       d = the maximum offering price per share on the last day of the period

                              CALCULATION OF YIELD
 
  The Fund calculates its yield quotations based on a 30-day period ended on the
date of the most recent balance sheet included in the registration statement, by
dividing the net investment income per share earned during the period by the
maximum offering price per share on the last day of the period, according to the
following formula:
                                       a - b    6
                      YIELD (y) = 2 [( ----- +1) - 1]
                                        cd
 
Where:  a  = dividends and interest earned during the period
 
        b  = expenses accrued for the period (net of reimbursements)
 
        c  = the average daily number of shares outstanding during the period
             that were entitled to receive dividends
 
        d  = the maximum offering price per share on the last day of the period

                              CALCULATION OF YIELD
 
     The Fund calculates its yield quotations based on a 30-day period ended on
the date of the most recent balance sheet included in the registration
statement, by dividing the net investment income per share earned during the
period by the maximum offering price per share on the last day of the period,
according to the following formula:
 


                                 a-b      6
              YIELD (y) = 2[  ( ----- + 1)  - 1]

Where: a = dividends and interest earned during the period
 
       b = expenses accrued for the period (net of reimbursements)
 
       c = the average daily number of shares outstanding during the period that
           were entitled to receive dividends
 
       d = the maximum offering price per share on the last day of the period

                              CALCULATION OF YIELD

  The Fund calculates its yield quotations based on a 30-day period ended on the
date of the most recent balance sheet included in the registration statement, by
dividing the net investment income per share earned during the period by the
maximum offering price per share on the last day of the period, according to the
following formula:
 
                                        a-b      6
                        YIELD (y) = 2[( ---- + 1)  - 1]
                                         cd
 
Where: a = dividends and interest earned during the period
 
       b = expenses accrued for the period (net of reimbursements)
 
       c = the average daily number of shares outstanding during the period that
           were entitled to receive dividends
 
       d = the maximum offering price per share on the last day of the period

                     FLORIDA INSURED TAX FREE INCOME FUND

                              CALCULATION OF YIELD
 

  The Fund calculates its yield quotations based on a 30-day period ended on the
date of the most recent balance sheet included in the registration statement, by
dividing the net investment income per share earned during the period by the
maximum offering price per share on the last day of the period, according to the
following formula:
 
                                      a-b     6
                      YIELD (y) = 2[(---- + 1) - 1]
                                      cd
 
Where: a = dividends and interest earned during the period
 
       b = expenses accrued for the period (net of reimbursements)
 
       c = the average daily number of shares outstanding during the period that
           were entitled to receive dividends
 
       d = the maximum offering price per share on the last day of the period

                              CALCULATION OF YIELD
 
  The Fund calculates its yield quotations based on a 30-day period ended on the
date of the most recent balance sheet included in the registration statement, by
dividing the net investment income per share earned during the period by the
maximum offering price per share on the last day of the period, according to the
following formula:
 
                                      a-b       6
                      YIELD (y) = 2[(------ + 1) - 1]
                                       cd
 
Where: a = dividends and interest earned during the period
 
       b = expenses accrued for the period (net of reimbursements)
 
       c = the average daily number of shares outstanding during the period that
           were entitled to receive dividends
 
       d = the maximum offering price per share on the last day of the period

                              CALCULATION OF YIELD
 

  The Fund calculates its yield quotations based on a 30-day period ended on the
date of the most recent balance sheet included in the registration statement, by
dividing the net investment income per share earned during the period by the
maximum offering price per share on the last day of the period, according to the
following formula:
 
                                    a-b     6
                   YIELD (y) = 2[( ---- + 1) -1]
                                    cd
 
Where: a = dividends and interest earned during the period
 
       b = expenses accrued for the period (net of reimbursements)
 
       c = the average daily number of shares outstanding during the period that
           were entitled to receive dividends
 
       d = the maximum offering price per share on the last day of the period

              time by the Trustees and set forth in the Funds' prospectus, 
              which may be reduced or eliminated for Money Market Funds,
              larger purchases, under a combined purchase privilege, under a
              right of accumulation, under a letter of intent or for certain
              categories of purchasers as permitted by Rule 22(d) of the Act
              and as set forth in the Fund's prospectus.  Class A Shares that
              are not subject to a front-end sales charge as a result of the
              foregoing, may be subject to a CDSC for the CDSC Period set forth
              in Section D.1.  The offering price of Shares subject to a
              front-end sales charge shall be computed in accordance with Rule
              22c-1 and Section 22(d) of the Act and the rules and regulations
              thereunder. Class A Shares shall be subject to ongoing Service
              Fees approved from time to time by the Trustees and set forth in
              the Funds' prospectus.  Although shares of Van Kampen American
              Capital Tax Free Money Market Fund are not designated as "Class A"
              they are substantially similar to Class A Shares as defined herein
              and shall be treated as Class A shares for the purposes of this
              Plan.
            
          2.  Class B Shares.  Class B Shares shall be (1) offered at net asset
              value, (2) subject to a CDSC for the CDSC Period set forth in
              Section D. 1, (3) subject to ongoing Service Fees and
              Distribution Fees  approved from time to time by the Trustees and
              set forth in the Funds' prospectus and (4) converted to Class A
              Shares three to ten years after the calendar month in which the
              shareholder's order to purchase was accepted, which number of
              years shall be as approved from time to time by the Trustees and
              set forth in the respective Fund's prospectus.

          3.  Class C Shares.  Class C Shares shall be  (1) offered at net
              asset value, (2) subject to a CDSC for the CDSC Period set forth
              in Section D. 1. , (3) subject to ongoing Service Fees and
              Distribution Fees approved from time to time by the Trustees and
              set forth in the Funds' prospectus and (4) prior to January 1,
              1997, converted to Class A Shares eight to fifteen years after 
              the calendar month in which the shareholder's order to purchase 
              was accepted, which number of years shall be as approved from 
              time to time by the Trustees and set forth in the respective 
              Fund's prospectus.

      C. Rights and Privileges of Classes.  Each Class of each Fund will
         represent an interest in the same portfolio of investments of that
         Fund and will have identical voting, dividend, liquidation and other
         rights, preferences, powers, restrictions, limitations,
         qualifications, designations and terms and conditions except as
         described otherwise herein.


      D. CDSC.  A CDSC may be imposed upon redemption of Class A Shares, Class
         B Shares and Class C Shares that do not incur a front end sales charge
         subject to the following conditions:

         1.  CDSC Period.  The CDSC Period for Class A Shares and Class C Shares
             shall be one year.  The CDSC Period for Class B Shares shall be at
             least three but not more than ten years as recommended by the
             Distributor and approved by the Trustees.

         2.  CDSC Rate.  The CDSC rate shall be recommended by the Distributor
             and approved by the Trustees.  If a CDSC is imposed for a period
             greater than one year the CDSC rate must decline during the CDSC
             Period such that (a) the CDSC rate is less in the last year of the
             CDSC Period than in the first and (b) in each succeeding year the
             CDSC rate shall be less than or equal to the CDSC rate in the
             preceding year.

         3.  Disclosure and Changes.  The CDSC rates and CDSC Period shall be
             disclosed in a Fund's prospectus and may be decreased at the
             discretion of the Distributor but may not be increased unless
             approved as set forth in Section L.

         4.  Method of Calculation.  The CDSC shall be assessed on an amount
             equal to the lesser of the then current market value or the cost of
             the Shares being redeemed.  No sales charge shall be imposed on
             increases in the net asset value of the Shares being redeemed above
             the initial purchase price.  No CDSC shall be assessed on Shares
             derived from reinvestment of dividends or capital gains
             distributions.  The order in which Class B Shares and Class C
             Shares are to be redeemed when not all of such Shares would be
             subject toa CDSC shall be as determined by the Distributor in
             accordance with the provisions of Rule 6c-10 under the Act.

         5.  Waiver.  The Distributor may in its discretion waive a CDSC
             otherwise due upon the redemption of Shares under circumstances
             previously approved by the Trustees and disclosed in the Fund's
             prospectus or statement of additional information and as allowed
             under Rule 6c-10 under the Act.

         6.  Calculation of offering price. The offering price of Shares subject
             to a CDSC shall be computed in accordance with Rule 22c-1 and
             Section 22(d) of the Act and the rules and regulations thereunder.

         7.  Retention by Distributor.  The CDSC paid with respect to Shares of
             a Fund may be retained by the Distributor to reimburse the
             Distributor for commissions paid by it in





<PAGE>   4


            connection with the sale of Shares subject to a CDSC and
            Distribution Expenses to the extent of such commissions and
            Distribution Expenses eligible for reimbursement and approved by
            the Trustees.

     E.  Service and Distribution Fees.  Class A Shares shall be subject to a
         Service Fee and Class B and Class C Shares shall be subject to a
         Service Fee and a Distribution Fee.  The Service Fee applicable to any
         class shall not exceed 0.25% per annum of the average daily net assets
         of the Class and the Distribution Fee shall not exceed 0.75% per annum
         of the average daily net assets of the Class.  All other terms and
         conditions with respect to Service Fees and Distribution Fees shall be
         governed by the plans adopted by the Fund with respect to such fees
         and Rule 12b-1 of the Act.

     F.  Conversion.  Shares purchased through the reinvestment of dividends
         and distributions paid on Shares subject to conversion shall be
         treated as if held in a separate sub-account .  Each time any Shares
         in a Shareholder's  account (other than Shares held in the sub-
         account) convert to Class A Shares, a proportionate number of Shares
         held in the sub-account shall also convert to Class A Shares.  All
         conversions shall be effected on the basis of the relative net asset
         values of the two Classes without the imposition of any sales load or
         other charge.  So long as any Class of Shares converts into Class A
         Shares, the Distributor shall waive or reimburse each Fund, or take
         such other actions with the approval of the Trustees as may be
         reasonably necessary, to ensure the expenses, including payments
         authorized under a Plan of Distribution, applicable to the Class A
         Shares are not higher than the expenses, including payments authorized
         under the Plan of Distribution, applicable to the class of shares
         converting into Class A Shares.

     G.  Allocation of Expenses, Income and Gains Among Classes.

         1.   Expenses applicable to a particular class.  Each Class of each
              Fund shall pay any Service Fee, Distribution Fee and CDSC
              applicable to that Class.  Other expenses applicable to a
              particular Class such as incremental transfer agency fees, but not
              including advisory or custodial fees or other expenses related to
              the management of the Fund's assets,  shall be allocated between
              Classes in different amounts if they are actually incurred in
              different amounts by the Classes or the Classes receive services
              of a different kind or to a different degree than other Classes.
         
         2.   Distribution Expenses.  Distribution Expenses actually
              attributable to the sale of all Classes shall be allocated to each
              Class based upon the ratio which sales of each Class bears to the
              sales of all Shares of the Fund.  For this purpose, Shares issued
              upon reinvestment of dividends or distributions, upon conversion
              from Class B Shares or Class C Shares to Class A Shares or upon
              stock splits will not be considered sales.

         3.   Income, capital gains and losses, and other expenses applicable to
              all Classes. Income, realized and unrealized capital gains and
              losses, and expenses such as advisory fees applicable to all
              Classes shall be allocated to each Class on the basis of the net
              asset value of that Class in relation to the net asset value of
              the Fund.





<PAGE>   5


         4.   Determination of nature of expenses.  The Trustees shall determine
              in their sole discretion whether any expense other than those
              listed herein is properly treated as attributed to a particular
              Class or all Classes.

     H.  Exchange Privilege.  Exchanges of Shares shall be permitted between
         Funds as follows.

         1.    General.  Shares of one Fund may be exchanged for Shares of the
               same Class of another Fund at net asset value and without sales
               charge, provided that

               a. The Distributor may specify that certain Funds may not be
                  exchanged within a designated period, which shall not exceed
                  90 days, after acquisition without prior Distributor approval.

               b. Class A Shares of a Money Market Fund  that were not acquired
                  in exchange for Class B or Class C Shares of a Fund may be
                  exchanged for Class A Shares of another Fund only upon payment
                  of the excess, if any, of the sales charge rate applicable to
                  the Shares being acquired over the sales charge rate
                  previously paid.

               c. Shares of a Money Market Fund acquired through an exchange of
                  Class B Shares or Class C Shares may be exchanged only for the
                  same Class of another Fund as the Class they were acquired in
                  exchange for or any Class into which those shares were
                  converted.

         2.    Target Fund.  Shares of Van Kampen American Capital Government
               Target Fund may be exchanged for Class A Shares of a Fund.

         3.    CDSC Computation.  The acquired Shares will remain subject to the
               CDSC rate schedule and CDSC Period for the original Fund upon the
               redemption of the Shares from the Van Kampen American Capital
               complex of funds. For purposes of computing the CDSC payable on a
               disposition of the new Shares, the holding period for the
               original Shares shall be added to the holding period of the new
               Shares.

     I.  Voting Rights of Classes.

         1.    Shareholders of each Class shall have exclusive voting rights on
               any matter submitted to them that relates solely to the Plan of
               Distribution related to that Class, provided that

               a.  If any amendment is proposed to the plan under which Service
                   Fees are paid with respect to Class A Shares of a Fund that
                   would increase materially the amount to be borne by Class A
                   Shares under that plan, then no Class B Shares or Class C
                   Shares shall convert into Class A Shares of that Fund until
                   the holders of Class B Shares and Class C Shares of that Fund
                   have also approved the proposed amendment.





<PAGE>   6


             b.  If the holders of either the Class B Shares and/or Class C
                 Shares referred to in subparagraph a. do not approve the
                 proposed amendment, the Trustees of the Fund and the
                 Distributor shall take such action as is necessary to ensure
                 that the Class voting against the amendment shall convert into
                 another Class identical in all material respects to Class A
                 Shares of the Fund as constituted prior to the amendment.

         2.  Shareholders shall have separate voting rights on any matter
             submitted to shareholders in which the interest of one Class
             differs from the interests of any other Class.

     J.  Dividends.  Dividends paid by a Fund with respect to each Class, to
         the extent any dividends are paid, will be calculated in the same
         manner at the same time on the same day and will be in substantially
         the same amount, except any Distribution Fees,Service Fees or
         incremental expenses relating to a particular Class will be borne
         exclusively by that Class.


     K.  Reports to Trustees.  The Distributor shall provide to the Trustees of
         each Fund quarterly and annual statements concerning distribution and
         Shareholder servicing expenditures complying with paragraph (b)(3)(ii)
         of Rule 12b-1 of the Act, as it may be amended from time to time.  The
         Distributors  also shall provide the Trustees such information as the
         Trustees may from time to time deem to be reasonably necessary to
         evaluate this Plan.

     L.  Amendment.  Any material amendment to this Plan shall be approved by
         the affirmative vote of a majority of the Trustees of a Fund,
         including the affirmative vote of the trustees of the Fund
         who are not interested persons of the Fund, except that any amendment
         that increases the CDSC rate schedule or CDSC Period must also be
         approved by the affirmative vote of a majority of the Shares of the
         affected Class.   The Distributor shall provide the Trustees such
         information as may be reasonably necessary to evaluate any amendment
         to this Plan.
