                           TAX FREE HIGH INCOME FUND
 
    Van Kampen Merritt Tax Free High Income Fund (the "Fund") is a separate
diversified mutual fund, organized as a sub-trust of Van Kampen Merritt Tax Free
Fund. 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
that a prospective investor should know before investing. Please read and retain
this Prospectus for future reference. The address of the Fund is One Parkview
Plaza, Oakbrook Terrace, Illinois 60181, and its telephone number is (800)
225-2222, ext. 6504.

(Continued from previous page.)
 
    The Fund currently offers three classes of its shares (the "Alternative
Sales Arrangements") 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 (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"). 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.
 
   
    Each class of shares pays ongoing distribution and service fees at an
aggregate annual rate of (i) for Class A Shares, up to 0.30% of the Fund's
average daily net assets attributable to the Class A Shares, (ii) for Class B
Shares, up to 1.00% of the Fund's average daily net assets attributable to the
Class B Shares and (iii) for Class C Shares up to 1.00% of the Fund's average
daily net assets attributable to the Class C Shares. Investors should understand
that the purpose and function of the deferred sales charge and the distribution
and service fees with respect to the Class A Share accounts over $1 million,
Class B Shares and Class C Shares are the same as those of the initial sales
charge and distribution and service fees with respect to the Class A Share
accounts below $1 million. Each share of the Fund represents an identical
interest in the investment portfolio of the Fund and has the same rights, except
that (i) each class of shares bears those distribution fees, service fees and
administrative expenses applicable to the respective class of shares as a result
of its sales arrangements, which will cause the different classes of shares to
have different expense ratios and to pay different rates of dividends, (ii) each
class 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) the
classes have different exchange privileges. Class B Shares automatically will
convert to Class A Shares seven 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. See "Purchasing
Shares of the Fund."

                               PROSPECTUS SUMMARY
- --------------------------------------------------------------------------------
 
THE FUND  The Van Kampen Merritt Tax Free High Income Fund (the "Fund") is a
separate diversified sub-trust of the Van Kampen Merritt Tax Free Fund, an
open-end management investment company organized as a Massachusetts business
trust. See "The Fund."
 
INVESTMENT OBJECTIVES AND POLICIES  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. 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 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
 
                                        4
<PAGE>   22
 
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 Objectives 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."
 
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 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 $1,000,000 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.
    
 
                                        5
<PAGE>   23
 
  The minimum initial investment with respect to the Class A Shares, Class B
Shares and Class C Shares is $1,000. The minimum subsequent investment with
respect to each class of shares is $100.
 
   
  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 0.30% 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 contingent deferred sales charge.
    
 
  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 contingent deferred sales charge 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 will automatically convert to Class A Shares seven 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 contingent deferred sales charge
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.
 
   
INVESTMENT ADVISER AND ADVISORY FEE  Van Kampen American Capital Investment
Advisory Corp. is the investment adviser for the Fund. The annual advisory fee
for the Fund is .50% of its average daily net assets, reduced on net assets over
$500 million. The Adviser utilizes at its own expense certain research services
of its affiliate, McCarthy, Crisanti & Maffei, Inc. See "Investment Advisory
Services."
    
 
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."
 
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
 
                                        6
<PAGE>   24
 
CDSC Shares will not be subject to a deferred sales charge. The Fund may require
redemption of its shares if the value of the account in the Fund is $500 or
less. See "Redemption of Shares."
 
    The above 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 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.
    
 
(2) The 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 Fund sold after the implementation date of such plans. Due to
    the incremental "phase-in" of the Fund's 12b-1 and service 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 0.30% of the net assets attributable to the
    Fund's Class A Shares. Accordingly, it is unlikely that future expenses will
    remain consistent with those disclosed in the fee table. See "The
    Distribution and Service Plans."

You would pay the following expenses on a $1,000
  investment, assuming (i) an operating expense
  ratio of 0.87% for Class A Shares, 1.64% for Class
  B Shares, and 1.64% for Class C Shares, (ii) 5%
  annual return and (iii) redemption at the end of
  each time period:
  Class A Shares....................................  $56     $74    $ 93   $150
  Class B Shares....................................  $57     $87    $104   $155
  Class C Shares....................................  $27     $52    $ 89   $194
An investor would pay the following expenses on the
  same $1,000 investment assuming no redemption at
  the end of each period:
  Class A Shares....................................  $56     $74    $ 93   $150
  Class B Shares....................................  $17     $52    $ 89   $155
  Class C Shares....................................  $17     $52    $ 89   $194
</TABLE>
    
 
  The purpose of the foregoing tables is to assist an investor in understanding
the various costs and expenses that an investor in the Fund will bear directly
or indirectly. The "Examples" reflect 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 Fund's 12b-1 plan with respect to Class A Shares,
it is anticipated that 12b-1 expenses will increase in accordance with such plan
to a maximum amount of 0.30% of the Class A Share's net assets. Accordingly, it
is unlikely that future expenses as projected will remain consistent with those
determined based on the table captioned "Annual Fund Operating Expenses." 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 "Investment Advisory Services" and "The Distribution and
Service Plans."

THE FUND
- --------------------------------------------------------------------------------
 
  Van Kampen Merritt Tax Free High Income Fund ("Fund") is a separate
diversified sub-trust of Van Kampen Merritt Tax Free Fund (the "Trust"), which
is an open-end management investment company, commonly known as a "mutual fund,"
organized as a Massachusetts 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.
 
  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 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
 
                                       13
<PAGE>   31
 
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 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
 
                                       14
<PAGE>   32
 
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
during the fiscal year ended December 31, 1994 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 1994
fiscal year, computed on a monthly basis.

  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.
 
  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
 
                                       16
<PAGE>   34
 
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 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 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
 
                                       17
<PAGE>   35
 
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 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.
 
                                       18
<PAGE>   36
 
  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. As described under "Investment Advisory Services," the
Adviser will utilize at its own expense credit analysis and research services
provided by its affiliate, McCarthy, Crisanti & Maffei, Inc. ("MCM"). 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 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, 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, 1994, approximately 6.49% and 0.04% of
    
 
                                       19
<PAGE>   37
 
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 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
 
                                       20
<PAGE>   38
 
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.
 
  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 high-grade municipal portfolio 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
 
                                       21
<PAGE>   39
 
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.
 
- --------------------------------------------------------------------------------
PURCHASING SHARES OF THE FUND
- --------------------------------------------------------------------------------
 
  The Fund has designated three classes of shares for sale to the public on a
continuous basis through Van Kampen American Capital Distributors, Inc., (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") who are acting
as securities dealers ("dealers") and through NASD members or eligible non-NASD
members who are acting as brokers or agents for investors ("brokers"). The Fund
reserves the right to suspend or terminate the continuous public offering at any
time and without prior notice.
 
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 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
    
 
                                       22
<PAGE>   40
 
   
(Class A Share accounts over $1 million, "Class B Shares" and "Class C Shares").
Class A Share accounts over $1,000,000 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 $1,000.
For purposes of purchasing shares of the Fund, "any person" shall have the
meaning set forth in the section of the Prospectus captioned "Purchasing Shares
of the Fund -- Initial Sales Charge Alternative -- Quantity Discounts." The
minimum subsequent investment with respect to each class of shares is $100. It
is presently the policy of the Distributor not to accept any order for Class B
Shares or Class C Shares in an amount of $1,000,000 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). Investors who intend to hold their shares for a
significantly long time may not wish to continue to bear the ongoing
distribution and service expenses of Class C Shares which, in the aggregate,
eventually would exceed the aggregate amount of initial sales charge and
distribution and service expenses applicable to Class A Shares, irrespective of
the fact that a CDSC would eventually not apply to a redemption of such Class C
Shares.
 
  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. Only the Class B Shares are subject to
a conversion feature (discussed below). Generally, a class of shares subject to
a higher
 
                                       23
<PAGE>   41
 
ongoing distribution fee, service fee or, where applicable, the conversion
feature will have a higher expense ratio and pay lower dividends than a class of
shares subject to a lower ongoing distribution fee, 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 "Net Asset Value."
 
  The administrative expenses that may be allocated to a specific class of
shares may consist of (i) transfer agency 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"Commission") 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 that shall be approved by
the Commission pursuant to an amended exemptive order. 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 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
securities 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. See "Net Asset Value."
 
  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
 
                                       24
<PAGE>   42
 
   
generated by the broker or dealer 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. 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. In addition,
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 are made by the Distributor out of its
own assets, and not out of the assets of the Fund. These programs will not
change the price an investor will pay for shares or the amount that the Fund
will receive from such sale.
    
 
INITIAL SALES CHARGE ALTERNATIVE
 
  Investors choosing the initial sales charge alternative purchase 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.

* No sales charge is payable at the time of purchase on investments of
  $1,000,000 or more, although for such investments the Fund imposes a
  contingent deferred sales charge 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 million, plus 0.20% on

<PAGE>   43
 
  the next $2 million and 0.08% on the excess over $5 million. See "Purchasing
  Shares of the Fund -- Deferred Sales Charge Alternatives" for additional
  information with respect to contingent deferred sales charges.
 
  QUANTITY DISCOUNTS. Purchasers of Class A Shares may be entitled to reduced
initial sales charges through a combination of investments, rights of
accumulation or a letter of intent (even if investors are not currently making
an investment of a size that would normally qualify for a quantity discount).
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, financial intermediary or the Distributor.
 
  For purposes of determining whether a purchase qualifies for a reduced initial
sales charge, the term "any person" is defined as any one of the following:
 
     (i) an individual, their spouse and children under the age of 21, trust or
         custodial accounts established for any of their sole benefit(s) and any
         corporation, partnership or sole proprietorship which is 100% owned,
         either alone or in combination, by any of the foregoing; or
 
    (ii) a trustee or other fiduciary purchasing for a single trust estate
         (including a pension, profit-sharing or other employee benefit trust
         created pursuant to a plan qualified under Section 401 of the Internal
         Revenue Code, as amended); or
 
   (iii) a "company" as defined in Section 2(a)(8) of the Investment Company
         Act.
 
  1. Combination of Investments. Purchases of Class A Shares of the Fund, or of
other Van Kampen Merritt funds distributed by the Distributor subject to an
initial sales charge ("ISC Shares"), which are made at any one time by "any
person" may be combined to receive a quantity discount.
 
  2. Rights of Accumulation. Under the rights of accumulation, in determining
the sales charge to be paid for a current purchase of Class A Shares "any
person" may combine their current purchase with the current public offering
price of Class A Shares of the Fund or, which are owned by such person. If the
account an investor is combining for rights of accumulation differs from the
account into which the investor's current purchase is placed, the investor must
indicate to the Transfer Agent the account number (and, if applicable, fund
name) of such other account.
 
  3. Letter of Intent. Purchasers of Class A Shares may qualify immediately for
a reduced sales charge by stating their intention to purchase an amount of Class
A Shares, during a 13 month period, that would qualify the investor for a
reduced sales charge. An investor may do this by signing a nonbinding Letter of
Intent, which may be signed at any time within 90 days after the first
investment to be included under the Letter of Intent. Class A Shares purchased
under the "Rights of Accumulation" described above (including investments in ISC
Shares) may be, at the time of the signing of the Letter of Intent,
 
                                       26
<PAGE>   44
 
applied towards completion of an investor's Letter of Intent. In addition, if an
investor's broker, dealer, or financial intermediary and the Distributor, agree
to refund the appropriate portion of their respective concessions to the Fund,
the sales charge on an investor's previous purchases made within 90 days may be
adjusted to the reduced sales charge under the Letter of Intent, and the
refunded concession will be used to purchase shares of the Fund at the public
offering price next determined after receipt of such monies. Each investment
made after signing the Letter of Intent will be entitled to the sales charge
applicable to the total investment indicated in the Letter of Intent. If an
investor does not complete the necessary purchases under the Letter of Intent
within 13 months from the date of the first purchase included thereunder, the
sales charge will be adjusted upward, corresponding to the amount actually
purchased.
 
  When an investor signs a Letter of Intent, Class A Shares purchased with a
value of 5% of the amount specified in the Letter of Intent will be restricted;
that is, these Class A Shares cannot be sold or redeemed until the Letter of
Intent is satisfied or the additional sales charges have been paid. If the total
purchases made under the Letter of Intent, less redemptions, equal or exceed the
amount specified in the Letter of Intent, these Class A Shares will no longer be
restricted. If the total purchases, less redemptions, exceed the amount so
specified, and qualify an investor for a further quantity discount, the
Distributor and the investor's securities broker, dealer or financial
intermediary will, upon request, remit their respective portions of the sales
concession and with that amount, purchase additional Class A Shares of the Fund
for the investor's account at the next computed offering price. If an investor
does not complete the necessary purchases under the Letter of Intent, the sales
charges will be adjusted upward and if, after written notice, the investor does
not pay the increased sales charge, sufficient restricted Class A Shares will be
redeemed to pay such charge.
 
  OTHER PURCHASE PROGRAMS. Purchasers of Class A Shares may be entitled to
reduced sales charges in connection with unit 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.
 
  1. Unit Trust Reinvestment Programs. The Fund will permit unitholders of unit
investment trusts to reinvest distributions from such trusts in Class A Shares
of the Fund and ISC Shares with no minimum initial or subsequent investment
requirement, and with a lower sales charge 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
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 securities broker, dealer, financial
intermediary or the Distributor.
 
                                       27
<PAGE>   45
 
  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 the Fund's transfer agent with
appropriate backup data for each participating investor in a computerized format
fully compatible with the transfer agent's 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.
    
 
2. NAV Purchase Options
 
  The classes of investors entitled to purchase shares of the Fund at net asset
value are as follows:
 
 (a) Current or retired Trustees/Directors of funds advised by Van Kampen
     American Capital Investment Advisory Corp., Van Kampen American Capital
     Asset Management, Inc. or John Govett & Co. Limited and such persons'
     families and their beneficial accounts. The term "families" includes a
     person's spouse, children and grandchildren, parents, and a person's
     spouse's parents.
 
 (b) Current or retired directors, officers and employees of VK/AC Holdings,
     Inc. and any of its subsidiaries, Clayton, Dubilier & Rice, Inc., employees
     of an investment subadviser to any such fund or an affiliate of such
     subadviser; and such persons' families and their beneficial accounts.
 
 (c) Directors, officers, employees and registered representatives of financial
     institutions that have a selling agreement with the Distributor and their
     spouses and minor children 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.
 
   
 (d) 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 the Fund alone, or in any combination of
     Class A Shares of the Fund and ISC Shares of other funds distributed by the
     Distributor as described herein under "Purchasing Shares of the Fund --
     Initial Sales Charge Alternative -- Quantity Discounts," during the 13
     month period commencing with the first investment pursuant hereto equals at
     least $1 million. The Distributor may pay such entities through which
     purchases are made an amount up to 0.50% of the amount invested, over a
     twelve month period following such transaction.
    
 
                                       28
<PAGE>   46
 
 (e) Trustees and other fiduciaries purchasing shares for retirement plans of
     organizations with retirement plan assets of $10 million or more. The
     Distributor may pay commissions of up to 1% for such purchases.
 
 (f) Accounts as to which a selling firm charges an account management fee
     ("wrap accounts"), provided the selling firm has executed a supplemental
     agreement to their existing selling agreement with the Distributor.
 
 (g) 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.
 
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 by such brokers, dealers and financial intermediaries,
which percentage rate will be equal to (i) 1.00% with respect to Class A Shares
in an amount of $1 million or more; (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. Sales compensation with respect to Class A
Shares subject to a CDSC is set forth under "Purchasing Shares of the Fund --
Initial Sales Charge Alternative".
 
  CDSC Shares redeemed within a specified period of time generally will be
subject to a contingent deferred sales charge at the rates set forth below. The
amount of the contingent deferred sales charge 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 contingent
deferred sales charge 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 contingent deferred sales charge applicable to a class of
CDSC Shares are paid to the Distributor and are used by the Distributor to
defray its expenses
 
                                       29
<PAGE>   47
 
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 contingent deferred sales charge and the distribution and
services 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 contingent deferred sales charge 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 contingent deferred sales charge 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, if any, and fourth of CDSC Shares held
longest during the period of time that a contingent deferred sales charge 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 (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).
 
  The contingent deferred sales charge is waived (i) on a redemption of shares
following the death of a shareholder, or (ii) to the extent that the redemption
represents a minimum required distribution from an IRA or other retirement plan
to a shareholder who has attained the age of 70 1/2.
 
   
  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 $1,000,000 or more,
although for such investments the Fund imposes a contingent deferred sales
charge 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 million, plus 0.20% on the next $2 million and 0.08% on the
excess over $5 million.

  CLASS B SHARES. Class B Shares redeemed within six years of purchase generally
will be subject to a contingent deferred sales charge at the rates set forth
below, charged as a percentage of the dollar amount subject thereto:

  The contingent deferred sales charge generally is waived on redemptions of
Class B Shares made pursuant to the Systematic Withdrawal Program. See
"Shareholder Programs -- Systematic Withdrawal Program."
 
  CLASS C SHARES. Class C Shares redeemed within the first twelve months of
purchase generally will be subject to a contingent deferred sales charge 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. Seven years after the end of the month in which a
shareholder's order to purchase a Class B Share of the Fund was accepted, such
Class B Share automatically will convert to a Class A Share and will no longer
be subject to the higher aggregate distribution and service fees. The purpose of
the conversion feature is to relieve the holders of Class B Shares that have
been outstanding for a period of time sufficient for the Distributor to have
been compensated for distribution expenses related to the Class B Shares from
most of the burden of such distribution-related expenses.
 
  For purposes of conversion to Class A Shares, Class B Shares purchased through
the reinvestment of dividends and distributions paid in respect of Class B
Shares in a shareholder's account will be considered to be held in a separate
sub-account. Each time any Class B Shares in the shareholder's account (other
than those in the sub-account) convert to Class A Shares, an equal pro rata
portion of the Class B Shares in the sub-account also will convert to Class A
Shares. The holding period applicable to a Class B Share acquired through the
use of the exchange privilege (discussed below) shall be the holding period
applicable to a Class B Share of such Fund acquired other than through use of
the exchange privilege. For purposes of calculating the holding period
applicable to a Class B Share of the Fund prior to conversion, a Class B Share
of the Fund issued in connection with an exercise of the exchange privilege, or
a series of exchanges, shall be deemed to have been issued on the date on which
the investor's order to purchase the exchanged Class B Share was accepted or, in
the case of a series of exchanges, when the investor's order to purchase the
original Class B Share was accepted.
 
                                       31
<PAGE>   49
 
  The conversion of Class B 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 transfer agency costs
with respect to Class B 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 Class B
Shares does not constitute a taxable event under federal income tax law. The
conversion of Class B Shares to Class A Shares may be suspended if such an
opinion is no longer available. In that event, no further conversions of Class B
Shares would occur, and Class B Shares might continue to be subject to the
higher aggregate distribution and service fees for an indefinite period.
 
- --------------------------------------------------------------------------------
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 the Fund's transfer agent receives payments for such shares.
However, shares become entitled to dividends on the day the Fund's transfer
agent 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 information under the "Distributions" section of the
Account Application bound in this Prospectus or available from Van Kampen
Merritt Funds, State Street Bank and Trust Company, c/o National Financial Data
Services, P.O. Box 419001, Kansas City, MO 64141-6001 (the "Transfer Agent").
After the Transfer Agent 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 to the Transfer Agent. This election may be made by telephone by
calling 1-800-341-2911 or in writing to the Transfer Agent. For inquiries
through Telecommunications Device for the Deaf (TDD) dial 1-800-772-8889 during
the hours of 7:30 a.m. to 4:00 p.m. Central Standard Time. If a shareholder
elects to change the method of distribution, such change will be effective only
with regard to distributions for which the record date is seven or more business
days after the Transfer Agent has received the request.
 
- --------------------------------------------------------------------------------
REDEMPTION OF SHARES
- --------------------------------------------------------------------------------
 
  WRITTEN REDEMPTION REQUEST. Shareholders may sell shares without charge (other
than, with respect to the CDSC Shares, any applicable contingent deferred sales
charge) at any time by mailing a written redemption request in proper form to
the Transfer Agent. This request should be sent to State Street Bank and Trust
Company, c/o National Financial Data Services, Van Kampen Merritt Funds, P.O.
Box 419001, Kansas City, MO 64141-6001. The request should indicate the number
of shares to be redeemed of a particular Fund, identify the account number and
be signed exactly as the shares are registered. If the amount being redeemed is
in excess of $50,000 or if the redemption proceeds will be sent to an address
other than the address of record, the signature(s) must be guaranteed by a
member firm of a principal stock exchange, a commercial bank or trust company
which is a member of the Federal Deposit Insurance Corporation, a credit union
or a savings association. The guarantee must state the words "Signature
Guaranteed" along with the name of the granting institution. Shareholders should
verify with the institution that it is an eligible guarantor prior to signing. A
guarantee from a notary public is not acceptable. If certificates are held for
the shares being redeemed, such certificates must be sent and endorsed for
transfer or accompanied by an endorsed stock power. Share certificates should be
sent by registered mail to National Financial Data Services, 1004 Baltimore
Avenue, Dwight Building, 6th Floor, Kansas City, MO 64105. Shareholders will
receive the net asset value per share next computed after the Transfer Agent
receives the redemption request and certificates (if any) in proper form. Any
applicable contingent deferred sales charge with respect to CDSC Shares redeemed
will be deducted from the redemption proceeds prior to transmittal of such
proceeds to the shareholder.
 
   
  TELEPHONE REDEMPTIONS. Shareholders may sell shares by calling the Fund at
1-800-341-2911 before 3:00 p.m. Central Standard Time to request a redemption.
For inquiries through Telecommunications Device for the Deaf (TDD), dial
1-800-772-8889, during the hours of 7:30 a.m. to 3:00 p.m. Central Standard
Time. There is a $500 minimum and a $1,000,000 maximum per request if the
redemption proceeds are to be mailed to the shareholder. If the redemption
proceeds are to be wired to a bank, there is a minimum of $5,000 and a
$1,000,000 maximum per request. Prior to redeeming shares by telephone the
"Expedited Telephone Redemption" section of either the Account Application or
Expedited Telephone Redemption and Exchange Request Form (the "Authorization")
    
 
                                       33
<PAGE>   51
 
must be completed and on file with the Transfer Agent. The signature(s) on the
Authorization must be guaranteed by a member firm of a principal stock exchange,
a commercial bank or trust company which is a member of the Federal Deposit
Insurance Corporation, a credit union or a savings association unless the
Authorization is completed at the time an account is originally established. A
redemption requested by telephone will be processed at the net asset value next
determined after receipt of the request. The proceeds will then be made payable
to the registered shareowner(s) and mailed to the address registered on the
account or wired to a bank, as requested on the Authorizations. Shareholders
cannot redeem shares by telephone if stock certificates are held for those
shares. This service is not available with respect to shares held in an
Individual Retirement Account (IRA) for which State Street Bank and Trust
Company acts as custodian. In addition, this service is not available with
respect to shares purchased by check until 15 days after purchase.
 
   
  By establishing the telephone redemption service, a shareholder authorizes the
Fund or its agent to act upon the instructions of any person by telephone to
redeem shares for any account for which such service has been authorized. The
Fund, the Distributor, the Transfer Agent and National Financial Data Services,
Inc. ("NFDS") employ procedures reasonably believed to confirm that instructions
communicated by telephone are genuine. Such procedures include requiring a
person attempting to redeem shares by telephone to provide, on a recorded line,
the name on the account, a social security number or tax identification number
and such additional information as may be included in the Authorization. A
shareholder also agrees that none of the Fund, the Distributor, the Transfer
Agent or National Financial Data Services ("NFDS") will be liable for any loss,
liability, cost or expense arising out of any request, including any fraudulent
or unauthorized request. This service may be amended or terminated at any time
by the Transfer Agent or the Fund. If a shareholder is unable to reach the Fund
by telephone, he or she may redeem shares pursuant to the procedures set forth
above under the caption "Written Redemption Requests." During periods of extreme
economic or market changes, it may be difficult for investors to reach the Fund
by telephone and to effect telephone redemptions.
    
 
  REDEMPTION THROUGH DEALERS. Shareholders may sell shares (whether in
certificate or book-entry form) through their securities dealer, who will
telephone the request to the Distributor. Shareholders will receive the net
asset value next determined after such shareholder places the sell order. Any
applicable contingent deferred sales charge with respect to CDSC Shares redeemed
will be deducted from the redemption proceeds prior to transmittal of such
proceeds to the shareholder. It is the responsibility of the shareholder's
broker, dealer or financial intermediary, to transmit the order to the
Distributor. Because the Fund generally determines net asset value once each
business day as of the close of business, sell orders placed through a
shareholder, 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 shareholder's order to be fulfilled on the basis of the
net asset value to be determined that day. Any change in the redemption price
due to the failure of the Distributor to receive a sell order prior to such time
must be settled between the investor and the broker or dealer submitting the
order.
 
                                       34
<PAGE>   52
 
The fund does not charge for this transaction (other than an applicable
contingent deferred sales charge). Shareholders must submit a written redemption
request in proper form to their securities dealer within five business days
after calling the dealer with the sell order. The request should indicate the
number of shares to be redeemed, identify the account number and the order or
confirmation number assigned to the trade, and be signed by the shareholder
exactly as the shares are registered. If the amount of the redemption exceeds
$50,000 or if the redemption proceeds will be sent to an address other than the
address of record, signature(s) must be guaranteed by a member firm of a
principal stock exchange, a commercial bank or trust company which is a member
of the Federal Deposit Insurance Corporation, credit unions and savings
association. The guarantee must state the words "Signature Guaranteed" along
with the name of the granting institution. Shareholders should verify with the
institution that it is an eligible guarantor prior to signing. A guarantee from
a notary public is not acceptable. If certificates are held for the shares being
redeemed, such certificates must be sent endorsed for transfer or accompanied by
an endorsed stock power. Certificates should be sent by registered mail to Van
Kampen Merritt Funds, c/o National Financial Data Services, 1004 Baltimore
Avenue, Dwight Building, 6th Floor, Kansas City, MO 64105.
 
   
  REDEMPTION UPON DISABILITY. The Fund will waive the CDSC on Class B Share
redemptions following the disability of a Class B shareholder. An individual
will be considered disabled for this purpose if he or she meets the definition
thereof in Section 72(m)(7) of the Internal Revenue Code (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 Fund will
require satisfactory proof of disability before it determines to waive the CDSC
on Class B Shares.
    
 
   
  In cases of disability, the CDSC on Class B 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 death or initial determination of disability. This waiver of the CDSC on
Class B 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. Whether shares are redeemed by the Fund or sold through a securities
dealer, a check for the proceeds (net of any required tax withholding and, with
respect to CDSC Shares, any applicable contingent deferred sales charge)
ordinarily will be mailed to shareholders or their dealer as the case may be
within seven calendar days after a redemption request or repurchase order and
share certificates (if any) are received in proper form as set forth above. Wire
transfers from the Fund of redemption proceeds, in the manner described above,
ordinarily will be transmitted to the shareholder within one business day. If
any shares are redeemed or repurchased shortly after purchase, the Fund will not
mail the proceeds until checks received for the purchase of shares have cleared,
 
                                       35
<PAGE>   53
 
which may take 10 days or more. The proceeds, of course, may be more or less
than the cost of the shares.
 
  The right of redemption or resale to the Fund may be suspended or the date of
payment postponed during any period when the New York Stock Exchange is closed
(other than customary weekend and holiday closings), when an emergency exists as
defined by rules and regulations of the Commission, or during any period when
the Commission has by order permitted such suspension or postponement.
 
  The Fund reserves the right to redeem any investment if the value of an
account falls below $500. Before the Fund makes such redemption it will provide
the shareholder with written notice and 30 days in which to make an additional
investment sufficient to increase the value of the account to at least $500.
 
- --------------------------------------------------------------------------------
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 sub-trust. 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.

PORTFOLIO TRANSACTIONS AND BROKERAGE ALLOCATIONS
- --------------------------------------------------------------------------------
 
  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.
 
- --------------------------------------------------------------------------------
THE 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 Investment
Company Act of 1940. 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, 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. Brokers, dealers and
financial intermediaries that have entered into Selling Agreements with the
Distributor and sell shares of the Fund are referred to herein as "financial
intermediaries."
 
  CLASS A SHARES. The Fund may spend an aggregate amount up to 0.30% 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 financial intermediaries and in connection with the
maintenance of such shareholders' accounts. The Fund pays the Distributor the
lesser of the balance of the 0.30% not paid to such 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
 
                                       38
<PAGE>   56
 
ongoing provision of services to holders of such shares by the Distributor and
by 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 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
financial intermediary's customers. The Fund pays the Distributor the lesser of
the balance of 0.75% not paid to such 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 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 contingent deferred sales charge. 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. The Fund will disclose in its prospectus from
time to time the then current amount of any such unreimbursed expenses with
respect to each class of CDSC Shares expressed as a dollar amount and as a
percent of the Fund's total net assets. As of December 31, 1994, there were
$149,879 and $17,410 of unreimbursed distribution expenses with respect to Class
B Shares and Class C Shares, respectively, representing 0.02% and 0.00% of the
Fund's total net assets. 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
contingent deferred sales charges.
    
 
                                       39

  Because the Fund is a sub-trust of the Trust, amounts paid to the Distributor
as reimbursement for expenses of one sub-trust of the Trust may indirectly
benefit the other funds which are sub-trusts 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 contingent deferred sales charge
applicable to a particular class of CDSC Shares to defray distribution related
expenses attributable to any other class of CDSC 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.
 
- --------------------------------------------------------------------------------
TAX STATUS
- --------------------------------------------------------------------------------
 
  FEDERAL TAXES. The Fund has qualified and intends to continue to qualify as a
regulated investment company under Subchapter M of the Internal Revenue Code of
1986, as amended (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 if it distributes to its shareholders at least 90% of its net
investment income (including tax-exempt interest and other taxable income
including 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 to satisfy the 90% distribution requirement. The Fund will not
be subject to federal income tax on any net capital gain distributed to its
shareholders. As a sub-trust of a Massachusetts business trust, the Fund will
not be subject to any excise or income taxes in Massachusetts as long as it
qualifies as a regulated investment company for federal income tax purposes.
 
  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 for such year and
at least 98% of its capital gain net income (the latter of which is generally
computed on the basis of the one-year period ending on October 31 of such year),
plus any required distribution 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 taxed in the hands of, the Fund will be treated
as having been distributed.
 
  If the Fund qualifies as a regulated investment company and satisfies the 90%
distribution requirement, and if, at the close of each quarter of the Fund's
taxable year, at least 50% of the total of the Fund's assets consists of
obligations exempt from federal income tax ("tax-exempt obligations"), the Fund
will be qualified to pay exempt-interest dividends to its shareholders to the
extent of its tax-exempt interest income (less expenses
 
                                       40
<PAGE>   58
 
applicable thereto). Exempt-interest dividends are excludable from a
shareholder's gross income for federal income tax purposes, but may be taxable
distributions for state, local and other tax purposes. Exempt-interest dividends
are included, however, 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. Interest expense with respect to indebtedness
incurred or continued by a shareholder to purchase or carry shares of the Fund
is not deductible to the extent that such interest relates to exempt-interest
dividends received from the Fund.
 
  Distributions of the Fund's investment company taxable income (which does not
include tax-exempt interest income) are taxable to shareholders as ordinary
income whether received in shares or in cash. Shareholders who receive
distributions in the form of additional shares will have a basis for federal
income tax purposes in each such share equal to the value thereof on the
reinvestment date. Distributions of the Fund's net capital gain ("capital gains
dividends"), if any, are taxable to shareholders at the rates applicable to
long-term capital gains regardless of the length of time shares of such Fund
have been held by such shareholders. Distributions in excess of the Fund's
earnings and profits, such as distributions of principal, will first reduce the
adjusted tax basis of the shares held by the shareholders and, after such
adjusted tax basis is reduced to zero, will constitute capital gains to such
shareholders (assuming such Shares are held as a capital asset). The Fund will
inform shareholders of the source and tax status of such distributions promptly
after the close of each calendar year. Distributions from the Fund will not be
eligible for the dividends received deduction for corporations.
 
  Exempt-interest dividends allocable to interest received by the Fund on
certain "private activity" obligations issued after August 7, 1986 will be
treated as interest on such obligations and thus will give rise to an item of
tax preference that will increase a shareholder's alternative minimum taxable
income. Unless otherwise provided in regulations, the portion of the Fund's
interest on such "private activity" obligations allocable to shareholders will
correspond to the portion of the Fund's total net tax-exempt income distributed
to shareholders. In addition, for corporations, alternative minimum taxable
income will be increased by a percentage of the amount by which a measure of
income that includes interest on tax-exempt obligations exceeds the amount
otherwise determined to be the alternative minimum taxable income. Accordingly,
investment in the Fund may cause shareholders to be subject to (or result in an
increased liability under) the alternative minimum tax.
 
  Exempt-interest dividends will not be tax-exempt to the extent made to any
shareholder who is a "substantial user" of the facilities financed by tax-exempt
obligations held by the Fund or "related persons" of such substantial users.
 
  Redemption or resale of shares of the Fund will be a taxable transaction for
federal income tax purposes. Redeeming shareholders will recognize gain or loss
in an amount equal to the difference between their basis in such redeemed shares
of the Fund 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 generally be long-term
if such shareholders have held shares for more than one year. Any loss realized
on shares held for six months or less will be disallowed to
 
                                       41
<PAGE>   59
 
the extent of any exempt-interest dividends received with respect to such
shares. If such loss is not entirely disallowed, it will be treated as a
long-term capital loss to the extent of any capital gains dividends received
with respect to such shares.
 
  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 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 closed out), 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
requirement for avoiding federal income 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.
 
  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 taxes. In order to
generate sufficient cash to make distributions necessary to satisfy the 90%
distribution requirement and avoid federal income taxes, the Fund may have to
dispose of securities that it would otherwise have continued to hold. Discount
relating to certain stripped tax-exempt obligations may constitute taxable
income when distributed to shareholders.
 
  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 gross income be derived from the disposition of securities
held for less than three months.
 
  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 a month and paid in January of the following
year will be treated as having been distributed by the Fund and received by the
shareholders on the December 31 of the year in which the dividend was declared.
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 is actually made.
 
  The Fund is required, in certain circumstances, to withhold 31% of taxable
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.
 
  GENERAL. The federal income tax discussion set forth above is for general
information only. Prospective investors should consult their tax advisers
regarding the specific federal
 
                                       42

tax consequences of holding and disposing of shares as well as the effects of
state, local and foreign tax laws.
 
- --------------------------------------------------------------------------------
SHAREHOLDER PROGRAMS
- --------------------------------------------------------------------------------
 
   
  SHARE CERTIFICATES.  As a rule, 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. In addition, if such certificates are lost, the shareholder must
write to State Street Bank and Trust Company, c/o National Financial Data
Services, P.O. Box 419001, Kansas City, MO 64141-6001, Attn: Van Kampen Merritt
Funds, requesting an "affidavit of loss" and to obtain a Surety Bond in a form
acceptable to the Transfer Agent. On the date the letter is received the
Transfer Agent will calculate no more than 2.00% of the net asset value of the
issued shares, and bill the party to whom the certificate was mailed.
    
 
   
  SYSTEMATIC WITHDRAWAL PROGRAM. If a shareholder's Class A Share account or
Class B Share account is valued at $10,000 or more, and such shareholder's
dividends are being reinvested, a requested dollar amount may be paid from such
account to any person monthly, quarterly, semiannually or annually. The minimum
amount that may be withdrawn each period is $50; withdrawals will be made on the
seventh business day of the month in which they are scheduled to occur.
Depending upon the size of the payments requested and the fluctuations in the
net asset value of the shares redeemed, redemptions for the purpose of making
such payments may reduce or even exhaust the amounts in such account. If an
investor acquires additional shares of the Fund after joining the Systematic
Withdrawal Program, the investor must inform the Fund if he or she wants the new
shares to be subject to the Systematic Withdrawal Program by telephoning the
Fund at 1-800-341-2911.
    
 
   
  With respect to redemptions of Class B Shares made pursuant to the Systematic
Withdrawal Program, an investor may annually redeem up to 12% of the net asset
value of the investor's initial investment in Class B Shares or, if the investor
does not join the program on the date of his or her initial investment, the net
asset value of the investor's Class B Shares on the date the investor elects to
participate in the Systematic Withdrawal Program. The Fund will waive the
contingent deferred sales charge applicable to Class B Shares redeemed pursuant
to the Fund's Systematic Withdrawal Program.
    
 
  It will ordinarily be disadvantageous to purchase shares (except through
reinvestment of distributions) while participating in a systematic withdrawal
program because a shareholder will be paying a sales charge to purchase shares
at the same time that shares are being redeemed upon which a sales charge may
already have been paid. Therefore, the Fund will not knowingly permit a
shareholder to make additional investments in shares of less than $5,000 if at
the same time such shareholder is making systematic withdrawals at a rate
greater than the distribution being paid on such shareholder's shares. The Fund
reserves the right to amend or terminate the systematic withdrawal program on
thirty days' notice, and a shareholder may withdraw from the program at any
time.

  EXCHANGE PRIVILEGE.  Any Class A Shares of the Fund which have been registered
in a shareholder's name for at least 15 days may be exchanged for ISC Shares of
any other Van Kampen Merritt mutual fund distributed by the Distributor offers
as exchange privilege. Under the exchange privilege, the Fund offers to exchange
its Class A Shares for ISC Shares on the basis of relative net asset value per
share. Any ISC Shares exchanged into the Fund that have been charged a sales
load lower than the sales load applicable to Class A Shares of the Fund will be
charged the applicable sales load differential upon exchange. ISC Shares of the
Van Kampen Merritt Money Market Fund and Van Kampen Merritt Tax Free Money Fund
which have not previously been charged a sales load (except for shares purchased
via the reinvestment option) will be charged the applicable sales load upon
exchange into the Fund.
 
  Class B Shareholders of the Fund may exchange their Class B Shares
("Outstanding Class B Shares") for Class B Shares of other Van Kampen Merritt
mutual funds sponsored by the Distributor ("New Class B Shares") on the basis of
relative net asset value per Class B Share, without the payment of any
contingent deferred sales charge that might otherwise be due on redemption of
the Outstanding Class B Shares. Class B Shares of the Fund acquired through use
of the exchange privilege will be 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.
 
   
  Class C Shares of the Fund are exchangeable for Class C Shares of other Van
Kampen Merritt mutual funds distributed by the Distributor on the same terms set
forth in the preceding paragraph with respect to Class B Shares, except that
Class C Shares do not convert to Class A Shares. The exchange privilege with
respect to any Van Kampen Merritt money market fund sponsored by the Distributor
is not available for Class C Shareholders.
    
 
   
  In order to qualify for the exchange privilege, it is required the shares
being exchanged have a net asset value of at least $1,000 (unless prior approval
has been obtained from the Fund). Shareholders also may effect an exchange by
telephone by calling the Fund at 1-800-341-2911 prior to 3:00 p.m. Central
Standard Time and requesting the exchange. For inquiries through
Telecommunications Device for the Deaf (TDD), dial 1-800-772-8889, during the
hours of 7:30 a.m. to 3:00 p.m. Central Standard Time. The exchange will be
processed at the net asset value next determined after receipt of such request.
By utilizing the telephone exchange service, a shareholder authorizes the Fund
or the Transfer Agent to act upon the instructions of any person by telephone to
exchange shares from any account for which such service has been authorized to
any identically registered account(s) with any Van Kampen Merritt fund
distributed by the Distributor which offers an exchange privilege. In addition,
a shareholder also agrees that none of the Fund, the Distributor, the Transfer
Agent nor NFDS will be liable for any loss, liability, cost or expense arising
out of any request, including any fraudulent request. The staff of the SEC
currently is reviewing its position with respect to such agreements. This
service may be amended or terminated at any time by the Transfer Agent or the
Fund. If a shareholder has certificates for any shares being exchanged, such
certificates must be surrendered prior to the exchange in the same manner as in
redemption of such shares (see "Redemption of
    
 
                                       44
<PAGE>   62
 
Shares--Telephone Redemptions"). Any shares exchanged between the Fund and any
of the other funds will begin earning dividends on the next business day after
the exchange is effected. 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.
 
  An exchange between Van Kampen Merritt funds pursuant to the exchange
privilege is treated as a sale for federal income tax purposes and, depending
upon the circumstances, a short- or long-term capital gain or loss may be
realized.
 
  The exchange privilege may be modified or terminated at any time, subject to
the requirement that the Fund give prominent notice thereof at least 60 days
prior to the effective date of the modification or termination in certain
circumstances. The Fund reserves the right to limit the number of times a
shareholder may exercise the exchange privilege.
 
  AUTOMATED MULTIPLE ACCOUNT SHAREHOLDER SERVICES (AMASSSM).
 
   
  1. 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
the Transfer Agent 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 the Transfer
Agent.
    
 
  2. Automated Dividend Programs.  The Fund will, upon the election of a
shareholder, automatically deposit the distributions from a shareholder's
account directly into a shareholder's bank account.
 
   
  3. Dividend Diversification.  In addition to the foregoing, monthly
distributions and any net long-term capital gain distributions to a
shareholder's account may be invested upon election by the shareholder in shares
of any other Van Kampen Merritt mutual fund distributed by the Distributor at
the then current net asset value, WITHOUT A SALES CHARGE. This election may be
made on the account application bound in this prospectus, by written notice to
the Transfer Agent or by calling the Fund directly at 1-800-341-2911, during the
hours of 7:00 a.m. to 7:00 p.m. Central Standard Time. For inquiries through
Telecommunications Device for the Deaf (TDD), dial 1-800-772-8889. In order to
qualify for this privilege, a shareholder must have established an account in
the other fund prior to electing this privilege. This privilege may be modified
or terminated by the Fund at any time.
    
 
                                       45
<PAGE>   63
 
  4. Easy Account Savings Enhancement Plan (EASESM).  Once a shareholder has
opened an account with the minimum $1,000 investment, the automatic investment
option may be utilized to make regular electronic monthly investments of $100 or
more into such shareholder's account with the Fund. In order to utilize this
option, a shareholder must fill out and sign the appropriate section of the
Application attached to this Prospectus or the EASESM application which is
available from the Transfer Agent, the Fund, such shareholder's broker or
dealer, or the Distributor. Once the Transfer Agent has received this
application, such shareholder's checking account at his or her designated local
bank will be debited each month in the amount authorized by such shareholder to
purchase shares of the Fund. Once enrolled in the EASESM program, a shareholder
may change the monthly amount or terminate participation at any time by writing
or calling the Transfer Agent. Shareholders in the EASESM program will receive a
confirmation of these transactions from the Fund at least quarterly and their
regular bank account statements will show the debit transaction each month.
 
  By electing to utilize any of the foregoing services, a shareholder authorizes
the Transfer Agent or its agent to act upon the instructions indicated in the
appropriate section of the Application in performing such services by either
withdrawing funds for deposit in the Fund pursuant to the EASESM Plan, or
depositing distributions and redemptions in the bank account indicated by the
voided check or deposit slip accompanying the shareholder's election or by
depositing the shareholder's distributions in the Van Kampen Merritt fund
account indicated. A shareholder also agrees that neither the Fund, the
Distributor, the Transfer Agent nor NFDS will be liable for any loss, liability,
cost or expense arising out of any request, including any fraudulent request.
This service may be amended or terminated at any time by the Transfer Agent or
by the Fund.
 
  REINSTATEMENT PRIVILEGE.  A shareholder who has redeemed Class A Shares or
Class B Shares may, within 120 days, repurchase Class A Shares of the Fund, or
shares of other Van Kampen Merritt mutual funds distributed by the Distributor,
in an amount of at least $500 and not exceeding the redemption proceeds
received, at a purchase price equal to the net asset value next determined after
the reinstatement request is received by the Transfer Agent or the Distributor.
A Class C Shareholder who has redeemed shares of the Fund may repurchase Class C
Shares of the Fund, or shares of other Van Kampen Merritt mutual funds
distributed by the Distributor with credit given for any contingent deferred
sales charge paid upon such redemption.
 
  Exercising the reinstatement privilege will not affect the character of any
gain or loss realized on the redemption for federal income tax purposes, except
that if the redemption resulted in a loss, the reinstatement may result in the
loss being disallowed under the "wash sale" rules.
 
- --------------------------------------------------------------------------------
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
 
                                       46
<PAGE>   64
 
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., Business
Week, Forbes or other industry publications.
 
   
  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 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
    
 
                                       47
<PAGE>   65
 
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.
 
  Please consult the Statement of Additional Information for more information
regarding the Fund's performance.

  State Street Bank and Trust Company, c/o National Financial Data Services,
P.O. Box 419001, Kansas City, MO 64141-6001, transfer agent for the Fund,
performs bookkeeping, data processing and administrative services related to the
maintenance of shareholder accounts. When an initial investment is made in the
Fund, an account will be opened for each shareholder on the Fund's books and
shareholders will receive a confirmation of the opening of the account.
Shareholders will receive monthly statements giving details of all activity in
their account during the quarter and will also receive a statement whenever an
investment or withdrawal is made in or from their account. Information for
federal income tax purposes will be provided at the end of the year. Such
statements will present separately information with respect to each class of a
Fund's shares. It is expected that the transfer agency costs attributable to the
Class B Shares and Class C Shares will be higher than the transfer agency costs
attributable to the Class A Shares.

DESCRIPTION OF SHARES OF THE FUND
- --------------------------------------------------------------------------------
 
  The Fund is a separate sub-trust of the Van Kampen Merritt Tax Free Fund, a
Massachusetts business trust organized August 15, 1985 (the "Trust"). Shares of
the Trust entitle their holders to one vote per share; however, separate votes
are taken by each sub-trust on matters affecting an individual sub-trust.
 
  The authorized capitalization of the Fund consists of an unlimited number of
shares of beneficial interest, without 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 "The
Distribution Plan and Service Plan."
 
  Pursuant to an order of the SEC, 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 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 Class B Shareholders and Class C Shareholders 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 a majority of the shares present and voting at
such meeting. The Trust will assist such holders in communicating with other
shareholders of the Fund to the extent required by the Investment Company 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 Standard & Poor's 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.

<PAGE>   69
 
<TABLE>
    <S>        <C>
    BBB        Debt rated 'BBB' is regarded as having an adequate capacity to
               pay interest and repay principal. Whereas it normally exhibits
               adequate protection parameters, adverse economic conditions or
               changing circumstances are more likely to lead to a weakened
               capacity to pay interest and repay principal for debt in this
               category than in higher rated categories.
 
    BB         Debt rated 'BB', 'B', 'CCC', 'CC' and 'C' is regarded, on
    B          balance, as predominantly speculative with respect to capacity
    CCC        to pay interest and repay principal. 'BB' indicates the least
    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.
 
    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.

<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.
 
    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.
</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 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. 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.
</TABLE>
 
                                       54
<PAGE>   72
 
<TABLE>
    <S>        <C>
    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.
</TABLE>
 
                                       55
<PAGE>   73
 
<TABLE>
    <S>        <C>
    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 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.
</TABLE>

<PAGE>   74
 
<TABLE>
    <S>        <C>
    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.
</TABLE>
 
        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.
 
        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
 
                                       57
<PAGE>   75
 
    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 senior debt obligations which have an original maturity
    not exceeding one year. 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 (or supporting institutions) have a superior
       ability for repayment of senior short-term debt obligations.
 
           Issuers rated Prime-2 (or supporting institutions) have a strong
       ability for repayment of senior short-term debt obligations.
 
           Issuers rated Prime-3 (or supporting institutions) have an acceptable
       ability for repayment of senior short-term debt obligations.
 
        Issuers rated Not Prime do not fall within any of the Prime rating
    categories.

                             THE FUND AND THE TRUST
 
   
  The Fund is a separate diversified sub-trust of Van Kampen Merritt Tax Free
Fund (the "Trust"), an open-end diversified management investment company,
commonly known as a mutual fund. The Trust is an unincorporated business trust
established under the laws of the Commonwealth of Massachusetts by a Declaration
of Trust dated August 15, 1985. The Declaration of Trust permits the Trustees to
issue an unlimited number of full and fractional shares in separate sub-trusts.
At present, the Fund, Van Kampen Merritt Insured Tax Free Income Fund, Van
Kampen Merritt California Insured Tax Free Fund, Van Kampen Merritt Municipal
Income Fund, Van Kampen Merritt Limited Term Municipal Income Fund, Van Kampen
Merritt Florida Insured Tax Free Income Fund, Van Kampen Merritt New Jersey Tax
Free Income Fund and Van Kampen Merritt New York Tax Free Income Fund have been
organized as sub-trusts of the Trust and have commenced investment operations.
Van Kampen Merritt California Tax Free Income Fund, Van Kampen Merritt Michigan
Tax Free Income Fund, Van Kampen Merritt Missouri Tax Free Income Fund and Van
Kampen Merritt Ohio Tax Free Income Fund have been organized as sub-trusts of
the Trust but have not commenced investment operations. Other sub-trusts 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 into a sub-trust of the Trust as of February 22, 1988.
    
 
  Each share of the Trust represents an equal proportionate interest in the
assets of its respective sub-trust with each other share in such sub-trust and
no interest in any other sub-trust. No sub-trust is subject to the liabilities
of any other sub-trust. The Declaration of Trust provides that shareholders are
not liable for any liabilities of the Trust or any of its sub-trusts, requires
inclusion of a clause to that effect in every agreement entered into by the
Trust or any of its sub-trusts 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 sub-trust on matters affecting an individual
sub-trust. For example, a change in investment policy for a sub-trust would be
voted upon by shareholders of only the sub-trust involved. 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 a
majority of the shares present and voting at such meeting.
 
  The Trustees may amend the Declaration of Trust (including with respect to any
sub-trust) in any manner without shareholder approval, except that the Trustees
may not adopt any amendment adversely affecting the rights of shareholders of
any sub-trust without approval by a majority of the shares of each affected
sub-trust 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.

                      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.
 
                                       B-2
<PAGE>   79
 
   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.)
 
   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.
 
   9. Invest in securities of other investment companies, except as part of a
      merger, consolidation or other acquisition and except that the Fund may
      invest up to 10% of its assets in tax exempt money market funds that
      invest in securities rated comparably to those the Fund may invest in so
      long as the Fund does not own more than 3% of the outstanding voting stock
      of any tax exempt money market fund or securities of any tax exempt money
      market fund aggregating in value more than 5% of the total assets of the
      Fund.
 
  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 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,
 
                                       B-3
<PAGE>   80
 
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 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
 
                                       B-4
<PAGE>   81
 
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 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 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
 
                                       B-5
<PAGE>   82
 
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 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.
 
  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
 
                                       B-6
<PAGE>   83
 
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.
 
                                       B-7
<PAGE>   84
 
  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 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
 
                                       B-8
<PAGE>   85
 
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 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 Investment Company Act of 1940 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 high-grade 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 high-grade 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, high-grade assets 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-
 
                                      B-10
<PAGE>   87
 
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 high-grade 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 Internal Revenue Code for qualification as a
regulated investment company. See "Tax Status" in the Prospectus.

* Interested persons of the Fund as defined in the 1940 Act.
 
  Each of the foregoing trustees acts as trustee for other investment companies
advised by the Adviser, each of the foregoing officers holds the same positions
with each of the investment companies advised by the Adviser.
 
   
  The compensation of the officers and Trustees who are affiliated persons (as
defined in the Investment Company Act of 1940) of the Adviser, Van Kampen
American Capital Distributors, Inc. or Van Kampen American Capital, Inc. is paid
by the respective entity. The Fund pays the compensation of all other officers
and Trustees. During the next year, the Fund expects to pay Trustees who are not
affiliated persons of the Adviser, Van Kampen American Capital Distributors,
Inc. or Van Kampen American Capital, Inc. $2,500 per year and $250 per meeting
of the Board of Trustees, plus expenses. Under the Fund's retirement plan,
trustees who are not affiliated with the Adviser, Van Kampen American Capital
Distributors, Inc. or Van Kampen American Capital, Inc., have at least ten years
of service and retire at or after attaining the age of 60, are eligible to
receive a retirement benefit equal to the annual retainer for each of the ten
years following such trustees's retirement. Under certain conditions, reduced
benefits are available for early retirement. Under the Fund's deferred
compensation plan, a trustee who is not affiliated with the Adviser, Van Kampen
American Capital Distributors, Inc. or Van Kampen American Capital, Inc. can
elect to defer receipt of all or a portion of the trustee's fees earned by such
trustee until such trustee's retirement. The deferred compensation earns a rate
of return determined by reference to the Fund or other Van Kampen Merritt mutual
funds advised by the Adviser as selected by the trustee. To the extent permitted
by the Investment Company Act, the Fund may invest in securities of other Van
Kampen Merritt mutual funds advised by the Adviser 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.

(1)   Messrs. Merritt and McDonnell, Trustees of each Fund during fiscal year
      1994, are affiliated persons of the Adviser and are not eligible for
      compensation or retirement benefits from the Funds.
    
 
   
(2)   The Registrant is Van Kampen Merritt Tax Free Fund (the "Trust") which
      currently is comprised of 8 sub-trusts, including the Fund. The amounts
      shown in this column are accumulated from the Aggregate Compensation of
      each of these 8 sub-trusts during such sub-trust's last completed fiscal
      year prior to the date of this Statement of Additional Information.
      Beginning in October 1994 each Trustee except Messrs. Gaughan and Whalen,
      began deferring his entire aggregate compensation paid by the Fund. The
      total combined amount of deferred compensation (including interest)
      accrued with respect to each Trustee as of December 31, 1994 is as
      follows: Mr. Kennedy, $14,737; Mr. Miller, $14,553; Mr. Nelson, $14,737
      and Mr. Robinson, $13,725.
    
 
   
(3)   The Retirement Plan commenced as of August 1, 1994 for the Fund. As of
      the end of the Fund's 1994 fiscal year, no amounts had been accrued for
      retirement benefits because such amounts were either zero or considered to
      be immaterial to the net assets of the Fund at such time. During the
      Fund's 1995 fiscal year, the Fund will accrue amounts for retirement
      benefits and include an amount, if any, for such Fund's 1994 fiscal year.
    
 
   
(4)   This is the estimated annual benefits payable per year for the 10-year
      period commencing in the year of such Trustee's retirement by a Fund
      assuming: the Trustee has 10 or more years of service on the Board of the
      Fund, retires at or after attaining the age of 60 and the annual retainer
      in the year prior to the Trustee's retirement is $2,500. Trustees retiring
      prior to the age of 60 or with fewer than 10 years of service for the Fund
      may receive reduced retirement benefits from such Fund.
    
 
   
(5)   The Fund Complex consists of 20 mutual funds advised by the Adviser. The
      amounts shown in this column are accumulated from the Aggregate
      Compensation of each of these 20 mutual funds in the Fund Complex during
      each fund's last completed fiscal year prior to the date of this Statement
      of Additional Information. The Adviser also serves as investment adviser
      for other mutual funds and closed-end investment companies; however, with
      the exception of Messrs. Merritt, McDonnell and Whalen, such mutual funds
      and closed-end investment companies do not have the same trustees as the
      Fund Complex. Combining the Fund Complex with other mutual funds and
      investment companies advised by the Adviser, Mr. Whalen received Total
      Compensation of $161,850.

                     INVESTMENT ADVISORY AND OTHER SERVICES
    
 
  Van Kampen American Capital Investment Advisory Corp. (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's principal
office is located at One Parkview Plaza, Oakbrook Terrace, Illinois 60181.
 
  The Adviser is a wholly-owned subsidiary of Van Kampen American Capital, Inc.,

Inc. is controlled, through the ownership of a substantial majority of its
common stock by The Clayton & Dubilier Private Equity Fund IV Limited
Partnership ("C&D L.P."), a Connecticut limited partnership. C&D L.P. is managed
by Clayton, Dubilier & Rice, Inc. a New York based private investment firm. The
General Partner of C&D L.P. is Clayton & Dubilier Associates IV Limited
Partnership ("C&D Associates L.P."). The general partners of C&D Associates L.P.
are Joseph L. Rice, III, B. Charles Ames, William A. Barbe, Alberto Cribiore,

own, in the aggregate, not more than 6% of the common stock of VK/AC Holding,
Inc. and have the right to acquire, upon the exercise of options, approximately
an additional 10% of the common stock of VK/AC Holding, Inc.
 
  The investment advisory agreement dated February 17, 1993, and approved by
shareholders of the Fund at a meeting held on January 14, 1993, 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 sub-trust, to whom the
Adviser renders periodic reports of the Fund's investment activities.
 
  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, 1994, 1993 and 1992, the Fund recognized
advisory expenses of $3,519,429, $2,939,428 and $2,980,018, 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.
 
                                      B-15
<PAGE>   92
 
   
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
Merritt mutual funds distributed by the Distributor 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% of such
cost being paid by the Fund and such other Van Kampen Merritt funds based
proportionally on their respective net assets.
    
 
   
  For the years ended December 31, 1994, 1993 and 1992, the Fund recognized
expenses of approximately $18,255, $13,900 and $9,810, respectively,
representing the Adviser's cost of providing accounting services.
    
 
  SUPPORT SERVICES AGREEMENT. Under a support services agreement with the
Distributor the Fund receives support services for shareholders, including the
handling of all written and telephonic communications, except initial order
entry and other distribution related communications. Upon entering into such
agreement, the Fund realized a reduction in the fee paid to the Transfer Agent.
Payment by the Fund for such services is made on cost basis for the employment
of the personnel and the equipment necessary to render the support services. The
Fund, and the other Van Kampen Merritt mutual funds distributed by the
Distributor, share such costs proportionately among themselves based upon their
respective net asset values.
 
   
  For the years ended December 31, 1994, 1993 and 1992, the Fund recognized
expenses of approximately $111,300, $246,825 and $201,796, respectively,
representing the Distributor's cost of providing certain support services.
    
 
  LEGAL SERVICES AGREEMENT. The Fund has entered into a Legal Services Agreement
pursuant to which Van Kampen American Capital, Inc. 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 Fund. 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. The Fund,
and the other Van Kampen Merritt mutual funds distributed by the Distributor,
share one half (50%) of such costs equally. The remaining one half (50%) of such
costs are allocated to specific funds based on specific time allocations, or in
the event services are attributable only to types of funds (i.e. closed-end or
open-end), the relative amount of time spent on each type of fund and then
further allocated between funds of that type based upon their respective net
asset values. The Fund has not yet incurred any expenses in connection with this
Agreement.
 
   
  For the years ended December 31, 1994, 1993 and 1992, the Fund recognized
expenses of approximately $40,000, $20,300 and $8,800, respectively,
representing Van Kampen American Capital, Inc.'s cost of providing legal
services.
    
 
   
  For the years ended December 31, 1994, 1993 and 1992, the Fund recognized
expenses of approximately $5,845, $15,600 and $13,000, respectively,
representing the Adviser's cost of providing pricing services.
    
 
                       CUSTODIAN AND INDEPENDENT AUDITORS
 
  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 auditors for the Fund are KPMG Peat Marwick LLP, Chicago,
Illinois. The selection of independent auditors will be subject to ratification
by the shareholders of the Fund at any annual meeting of shareholders.
 
                                      B-16
<PAGE>   93
 
                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 sub-trust.
 
   
  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.
    
 
  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 each of its sub-trusts, including the Fund, will be treated as
separate corporations for income tax purposes. The Fund may be subject to tax if
it fails to distribute net capital gains, or if its annual distributions, as a
percentage of its income, are less than the distributions required by tax laws.

                                THE DISTRIBUTOR
 
  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 Van Kampen American Capital, Inc., which is a subsidiary of
VK/AC Holding, Inc., a Delaware corporation that is controlled through an
ownership of a substantial majority of its common stock, by The Clayton &
Dubilier Private Equity Fund IV Limited Partnership ("C & D L.P."), a
Connecticut limited partnership. In addition, certain officers, directors and
employees of Van Kampen American Capital, Inc., and its subsidiaries own, in the
aggregate not more than 6% of the common stock of VK/AC Holding, Inc. and have
the right to acquire, upon the exercise of options, approximately an additional
10% of the common stock of VK/AC Holding, Inc. C & D L.P. is managed by Clayton,
Dubilier & Rice, Inc. Clayton & Dubilier Associates IV Limited Partnership ("C &
D Associates L.P.") is the general partner of C & D L.P. 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.
 
  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 such class, respectively. The Distribution Plan and
the Service Plan are being implemented through an agreement (the "Distribution
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 banks 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 banks 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 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 Agreement and/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 Agreement will be less
than the maximum percentage amount permissible with respect to such class of
shares under the Distribution Agreement.
 
  The Distributor must submit quarterly reports to the Board of Trustees of the
Trust, of which the Fund is a sub-trust, 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 year ended December 31, 1994, the Fund has recognized expenses under
the Plans of $1,678,218, $906,729 and $77,984 for the Class A Shares, Class B
Shares and Class C Shares, respectively, of which
    
 
                                      B-18
<PAGE>   95
 
   
$1,363,530 and $224,918 represent payments to financial intermediaries under the
Selling Agreements for Class A Shares and Class B Shares, respectively. For the
year ended December 31, 1994, the Fund has reimbursed the Distributor $147,920
and $710 for advertising expenses, and $91,343 and $44,696 for compensation of
the Distributor's sales personnel for the Class A Shares and Class B Shares,
respectively.

estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis

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,
1994, 20% of the Fund's net assets consisted of such securities. Short-term
securities with remaining maturities of less than 60 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" and "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, 1994, the Fund had an accumulated capital loss
carryforward for tax purposes of $43,939,891. Of this amount, $438,972 and
$43,500,919 will expire on December 31, 1999 and 2002, respectively. Net
realized gains or losses may differ for financial and tax reporting purposes
primarily as a result of the deferral of post October 31 losses 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. 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.


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>

First $500 million...  .50 of 1%
Over $500 million....  .45 of 1%
</TABLE>


For the year ended December 31, 1994, the Fund recognized expenses of   
approximately $101,700 representing legal services provided by 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, 1994, the Fund recognized expenses of
approximately $175,400 representing Van Kampen American Capital Distributors,
Inc.'s or its affiliates' ("VKAC") cost of providing accounting, legal,
portfolio pricing and certain shareholder services to the Fund.

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 Class B, C and D 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, 1994
- --------------------------------------------------------------------------------

For the year ended December 31, 1994, VKAC, as distributor for the Fund,
received net commissions on sales of the Fund's Class A shares of approximately
$536,200 and CDSC on the redeemed shares of Classes B, C and D of approximately
$295,300. Sales charges do not represent expenses of the Fund.

4. Investment Transactions

Aggregate purchases and cost of sales of investment securities, excluding
short-term notes and reorganization and restructuring costs, for the year ended
December 31, 1994, were $720,256,501 and $720,193,261, 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 for exercised option contracts where the
recognition of gain or loss is postponed until the disposal of the security
underlying the option 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, 1994, were as follows:

<TABLE>

                                       ---------  -------------
</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.

The fluctuation in market value of the contracts is settled daily through a     
cash margin account. Realized gains and losses are recognized when the contracts
are closed or expire.

Transactions in futures contracts for the year ended December 31, 1994, 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
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. 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 (the
"Distribution Plan") pursuant to Rule 12b-1 under the Investment Company Act of
1940 and a service plan (the "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 .30% each for Class A and Class D shares
and 1.00% each for Class B and Class C shares are accrued daily. Included in
these fees for the year ended December 31, 1994 are payments to VKAC of
approximately $997,400.

    Van Kampen Merritt Municipal Income Fund (the "Fund") is a separate
diversified mutual fund, organized as a sub-trust of Van Kampen Merritt Tax Free
Fund. 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 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 ("Moody's"). Up to 20% of the Fund's
total assets may consist of tax-exempt municipal securities rated below
investment grade (but not rated lower than B- by S&P or B3 by Moody's) and
unrated tax-exempt municipal securities believed by the Fund's investment
adviser to be of comparable quality, which involve special risk considerations.
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." The
Fund may invest a substantial portion of its assets in municipal securities that
pay interest that is subject to the alternative minimum tax. There is no
assurance that the Fund will achieve its investment objectives.
 
    The investment adviser for the Fund is Van Kampen American Capital
Investment Advisory Corp. This Prospectus sets forth the information about the
Fund that a prospective investor should know before investing in the Fund.

(Continued from previous page.)
 
    The Fund currently offers three classes of its shares (the "Alternative
Sales Arrangements") 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 (i) at the time of purchase (the "Class A Shares") or (ii) on a
contingent deferred basis (Class A Share accounts over $1 million, "Class B
Shares" and "Class C Shares"). 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.
 
   
    Each class of shares pays ongoing distribution and service fees at an
aggregate annual rate of (i) for Class A Shares, up to 0.30% of the Fund's
average daily net assets attributable to the Class A Shares, (ii) for Class B
Shares, up to 1.00% of the Fund's average daily net assets attributable to the
Class B Shares and (iii) for Class C Shares up to 1.00% of the Fund's average
daily net assets attributable to the Class C Shares. Investors should understand
that the purpose and function of the deferred sales charge and the distribution
and service fees with respect to the Class A Share accounts over $1 million,
Class B Shares and Class C Shares are the same as those of the initial sales
charge and distribution and service fees with respect to the Class A Share
accounts below $1 million. Each share of the Fund represents an identical
interest in the investment portfolio of the Fund and has the same rights, except
that (i) each class of shares bears those distribution fees, service fees and
administrative expenses applicable to the respective class of shares as a result
of its sales arrangements, which will cause the different classes of shares to
have different expense ratios and to pay different rates of dividends, (ii) each
class 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) the
classes have different exchange privileges. Class B Shares automatically will

                               PROSPECTUS SUMMARY
- --------------------------------------------------------------------------------
 
THE FUND  Van Kampen Merritt Municipal Income Fund (the "Fund") is a separate
diversified sub-trust of an open-end, diversified sub-trust of an open-end
management investment company organized as a Massachusetts business trust. See
"The Fund."
 
INVESTMENT OBJECTIVE AND POLICIES  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. 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 ("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 objectives. 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 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."
 
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
 
                                        4
<PAGE>   117
 
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 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.
    
 
  The minimum initial investment with respect to each of the Class A Shares,
Class B Shares and Class C Shares is $1,000. The Minimum subsequent investment
with respect to each class of shares is $100.
 
   
  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 0.30% 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 contingent deferred sales charge.
    
 
  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 contingent deferred sales charge 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 will convert to Class A Shares six 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 contingent deferred sales charge
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.
 
   
INVESTMENT ADVISER AND ADVISORY FEE  Van Kampen American Capital Investment
Advisory Corp. (the "Adviser"), is the investment adviser for the Fund. The
annual advisory fee for the Fund is 0.50% of its average daily net assets,
reduced on net assets over certain amounts. See "Investment Advisory Services."
    
 
                                        5
<PAGE>   118
 
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."
 
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. The Fund may require the redemption of shares if the value of an account
is $500 or less. See "Redemption of Shares."
 
    The above is qualified in its entirety by reference to the more detailed
              information appearing elsewhere in this Prospectus.

THE FUND
- --------------------------------------------------------------------------------
 
  Van Kampen Merritt Municipal Income Fund (the "Fund") is a separate
diversified sub-trust of Van Kampen Merritt Tax Free Fund (the "Trust"), which
is an open-end management investment company, commonly known as a "mutual fund,"
organized as a Massachusetts 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 ("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 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.
 
                                       12
<PAGE>   125
 
  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.
 
- --------------------------------------------------------------------------------
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 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
 
                                       13
<PAGE>   126
 
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 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
 
                                       14
<PAGE>   127
 
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."
 
  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.
 
                                       15
<PAGE>   128
 
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 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 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 high-grade municipal portfolio securities having an
aggregate value equal to the amount of such purchase commitments until payment
is made. The Fund will make commitments to
    
 
                                       17
<PAGE>   130
 
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.
 
  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.
 
  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.

- --------------------------------------------------------------------------------
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.
 
  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, 1994 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
 
                                       19
<PAGE>   132
 
are based on the dollar-weighted average of credit ratings of all municipal
securities held by the Fund during the 1994 fiscal year, computed on a monthly
basis.

- --------------------------------------------------------------------------------
PURCHASING SHARES OF THE FUND
- --------------------------------------------------------------------------------
 
  The Fund has designated three classes of shares for sale to the public on a
continuous basis through Van Kampen American Capital Distributors, Inc., (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") who are acting
as securities dealers ("dealers") and through NASD members or eligible non-NASD
members who are acting as brokers or agents for investors ("brokers"). The Fund
reserves the right to suspend or terminate the continuous public offering of its
shares at any time and without prior notice.
 
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 fees with respect to each class of shares that may be incurred over
the anticipated duration of their investment in the Fund.
 
                                       20
<PAGE>   133
 
   
  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 $1,000,000
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 $1,000.
For purposes of purchasing shares of the Fund, "any person" shall have the
meaning set forth in the section of the Prospectus captioned "Purchasing Shares
of the Fund -- Initial Sales Charge Alternative -- Quantity Discounts." The
minimum subsequent investment with respect to each class of shares is $100. It
is presently the policy of the Distributor, not to accept any order for Class B
Shares or Class C Shares in an amount of $1,000,000 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). Investors who intend to hold their shares for a
significantly long time may not wish to continue to bear the ongoing
distribution and service expenses of Class C Shares which in the aggregate,
eventually would exceed the aggregate amount of initial sales charge and
distribution and service expenses applicable to Class A Shares, irrespective of
the fact that a CDSC would eventually not apply to a redemption of such Class C
Shares.
 
  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
 
                                       21
<PAGE>   134
 
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. Only the Class B
Shares are subject to a conversion feature (discussed below). Generally, a class
of shares subject to a higher ongoing distribution fee, service fee or, where
applicable, the conversion feature will have a higher expense ratio and pay
lower dividends than a class of shares subject to a lower ongoing distribution
fee, 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 "Net Asset Value."
 
  The administrative expenses that may be allocated to a specific class of
shares may consist of (i) transfer agency 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 that shall be approved by the SEC pursuant to
an amended exemptive order. 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 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
securities 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. See "Net Asset
Value."
 
  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
 
                                       22
<PAGE>   135
 
   
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. 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. In addition,
the Distributor may provide additional compensation to Edward D. Jones & Co.
("Edward D. Jones") or an affiliate thereof based on a combination of its sales
of shares and increases in assets under management. In addition, the Distributor
is sponsoring a sales contest for INVEST Financial Corporation ("INVEST")
relating to the Fund and other funds distributed by the Distributor, pursuant to
which the Distributor may provide an INVEST broker an award valued up to $750.00
for sales of such funds during the period April 1, 1995, through May 31, 1995.
Such payments are made by the Distributor out of its own assets, and not out of
the assets of the Fund. These programs will not change the price an investor
pays for shares or the amount that the Fund will receive from such sale.
    
 
INITIAL SALES CHARGE ALTERNATIVE--CLASS A SHARES
 
  The public offering price of Class A Shares for purchasers choosing the
initial sales charge alternative 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 an 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
 
                                       23
<PAGE>   136
 
90% or more of the sales charge may be deemed to be "underwriters" as that term
is defined in the Securities Act of 1933.

* No sales charge is payable at the time of purchase on investments of
  $1,000,000 or more, although for such investments the Fund imposes a
  contingent deferred sales charge 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 million, plus 0.20% on the next $2 million and
  0.08% on the excess over $5 million. See "Purchasing Shares Of The Fund --
  Deferred Sales Charge Alternatives" for additional information with respect to
  contingent deferred sales charges.
    
 
  QUANTITY DISCOUNTS. Purchasers of Class A Shares may be entitled to reduced
initial sales charges through a combination of investments, rights of
accumulation or a letter of intent (even if an investor is not making an
investment of a size that normally would qualify for a quantity discount).
Investors, or their broker, dealer or financial intermediary, 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.
 
  For purposes of determining whether a purchase qualifies for a reduced initial
sales charge, the term "any person" is defined as any one of the following:
 
     (i) an individual, their spouse and children under the age of 21, trust or
         custodial accounts established for any of their sole benefit(s) and any
         corporation, partnership or sole proprietorship which is 100% owned,
         either alone or in combination, by any of the foregoing; or
 
     (ii) a trustee or other fiduciary purchasing for a single trust estate
          (including a pension, profit-sharing or other employee benefit trust
          created pursuant to a plan qualified under Section 401 of the Internal
          Revenue Code, as amended); or
 
    (iii) a "company" as defined in Section 2(a)(8) of the Investment Company
          Act of 1940 (the "Investment Company Act").

  1. Combination of Investments. Purchases of Class A Shares of the Fund, or of
other Van Kampen Merritt funds distributed by the Distributor subject to an
initial sales charge ("ISC Shares"), which are made at any one time by "any
person" may be combined to receive a quantity discount.
 
  2. Rights of Accumulation. Under the rights of accumulation, in determining
the sales charge to be paid for a current purchase of Class A Shares, "any
person" may combine their current purchase with the current public offering
price of Class A Shares of the Fund or ISC Shares, which are owned by such
person. If the account an investor is combining for rights of accumulation
differs from the account into which the investor's current purchase is placed,
the investor must indicate to the Transfer Agent the account number (and, if
applicable, fund name) of such other account.
 
  3. Letter of Intent. Purchasers of Class A Shares may qualify immediately for
a reduced sales charge by stating their intention to purchase an amount of Class
A Shares, during a 13 month period, that would qualify the investor for a
reduced sales charge. An investor may do this by signing a nonbinding Letter of
Intent, which may be signed at any time within 90 days after the first
investment to be included under the Letter of Intent. Class A Shares purchased
under the "Rights of Accumulation" described above (including investments in ISC
Shares) may be, at the time of the signing of the Letter of Intent, applied
towards completion of an investor's Letter of Intent. In addition, if an
investor's broker, dealer or financial intermediary and the Distributor agree to
refund the appropriate portion of their respective concessions to the Fund, the
sales charge on an investor's previous purchases made within 90 days may be
adjusted to the reduced sales charge under the Letter of Intent, and the
refunded concession will be used to purchase shares of the Fund at the public
offering price next determined after receipt of such monies. Each investment
made after signing the Letter of Intent will be entitled to the initial sales
charge applicable to the total investment indicated in the Letter of Intent. If
an investor does not complete the necessary purchases under the Letter of Intent
within 13 months from the date of the first purchase included thereunder, the
sales charge will be adjusted upward, corresponding to the amount actually
purchased.
 
  When an investor signs a Letter of Intent, Class A Shares of the Fund
purchased with a value of 5% of the amount specified in the Letter of Intent
will be restricted; that is, these Class A Shares cannot be sold or redeemed
until the Letter of Intent is satisfied or the additional sales charges have
been paid. If the total purchases made under the Letter of Intent, less
redemptions, equal or exceed the amount specified in the Letter of Intent, these
Class A Shares will no longer be restricted. If the total purchases, less
redemptions, exceed the amount so specified, and qualify an investor for a
further quantity discount, the Distributor and the investor's securities broker,
dealer or financial intermediary will, upon request, remit their respective
portions of the sales concession and with that amount, purchase additional Class
A Shares of the Fund for the investor's account at the next determined public
offering price. If an investor does not complete the necessary purchases under
the Letter of Intent, the sales charges will be adjusted upward and if, after
written notice, the investor does not pay the increased sales charge, sufficient
restricted Class A Shares will be redeemed to pay such charge.

  OTHER PURCHASE PROGRAMS. Purchasers of Class A Shares may be entitled to
reduced initial sales charges in connection with unit 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.
 
  1. Unit Trust Reinvestment Programs. The Fund permits unitholders of unit
investment trusts to reinvest distributions from such trusts in Class A Shares
of the Fund and other ISC Shares with no minimum initial or subsequent
investment requirement, and with a lower sales charge 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
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 dealer or broker, 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 securities broker or dealer 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 the Fund's transfer agent with
appropriate backup data for each participating investor in a computerized format
fully compatible with the transfer agent's 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.
    
 
2. NAV Purchase Options
 
  The classes of investors entitled to purchase shares of the Fund at net asset
value are as follows:
 
  (a) Current or retired Trustees/Directors of funds advised by Van Kampen
     American Capital Investment Advisory Corp., Van Kampen American Capital
     Asset Management, Inc. or John Govett & Co. Limited and such persons'
     families and their beneficial accounts. The term "families" includes a
     person's spouse, children and grandchildren, parents, and a person's
     spouse's parents.
 
  (b) Current or retired directors, officers and employees of VK/AC Holdings,
     Inc. and any of its subsidiaries, Clayton, Dubilier & Rice, Inc., employees
     of an investment
 
                                       26
<PAGE>   139
 
     subadviser to any such fund or an affiliate of such subadviser; and such
     persons' families and their beneficial accounts.
 
  (c) Directors, officers, employees and registered representatives of financial
     institutions that have a selling agreement with the Distributor and their
     spouses and minor children 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.
 
   
  (d) 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 the Fund alone, or in any combination of
     Class A Shares of the Fund and ISC Shares of other funds distributed by the
     Distributor as described herein under "Purchasing Shares of the Fund --
     Initial Sales Charge Alternative -- Quantity Discounts," during the 13
     month period commencing with the first investment pursuant hereto equals at
     least $1 million. The Distributor may pay such entities through which
     purchases are made an amount up to 0.50% of the amount invested, over a
     twelve month period following such transaction.
    
 
  (e) Trustees and other fiduciaries purchasing shares for retirement plans of
     organizations with retirement plan assets of $10 million or more. The
     Distributor may pay commissions of up to 1% for such purchases.
 
  (f) Accounts as to which a selling firm charges an account management fee
     ("wrap accounts"), provided the selling firm has executed a supplemental
     agreement to their existing selling agreement with the Distributor.
 
  (g) 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.
 
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) 1.00% with respect to
Class A Shares in an amount of $1 million or more; (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. Sales compensation with
respect to Class A Shares subject to a CDSC is set forth under "Purchasing
Shares of the Fund--Initial Sales Charge Alternative".
 
                                       27
<PAGE>   140
 
  CDSC Shares redeemed within a specified period of time generally will be
subject to a contingent deferred sales charge at the rates set forth below. The
amount of the contingent deferred sales charge 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 contingent
deferred sales charge 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 contingent deferred sales charge 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 contingent deferred sales charge and the
distribution and service 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 contingent deferred sales charge 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 contingent deferred sales charge 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, if any, and fourth of CDSC Shares held
longest during the period of time that a contingent deferred sales charge 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).
 
  The contingent deferred sales charge is waived (i) on a redemption of shares
following the death of a shareholder, or (ii) to the extent that the redemption
represents a minimum required distribution from an IRA or other retirement plan
to a shareholder who has attained the age of 70 1/2.
 
                                       28
<PAGE>   141
 
   
  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 $1,000,000 or more,
although for such investments the Fund imposes a contingent deferred sales
charge 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 million, plus 0.20% on the next $2 million and 0.08% on the
excess over $5 million.
    
 
  CLASS B SHARES. Class B Shares redeemed within six years of purchase generally
will be subject to a contingent deferred sales charge at the rates set forth
below, charged as a percentage of the dollar amount subject thereto:

  The contingent deferred sales charge generally is waived on redemptions of
Class B Shares made pursuant to the Systematic Withdrawal Program. See
"Shareholder Programs -- Systematic Withdrawal Program."
 
  CLASS C SHARES. Class C Shares redeemed within the first twelve months of
purchase generally will be subject to a contingent deferred sales charge 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. Six years after the end of the month in which a
shareholder's order to purchase a Class B Share of the Fund was accepted, such
Class B Share automatically will convert to a Class A Share and will no longer
be subject to the higher aggregate distribution and service fees. The purpose of
the conversion feature is to relieve the holders of Class B Shares that have
been outstanding for a period of time sufficient for the Distributor to have
been compensated for distribution expenses related to the Class B Shares from
most of the burden of such distribution-related expenses. The Fund does not
expect to issue any stock certificates upon conversion.
 
  For purposes of conversion of Class A Shares, Class B Shares purchased through
the reinvestment of dividends and distributions paid in respect of Class B
Shares in a shareholder's account will be considered to be held in a separate
sub-account. Each time any Class B Shares in the shareholder's account (other
than those in the sub-account) convert to Class A Shares, an equal pro rata
portion of the Class B Shares in the sub-account also will convert to Class A
Shares. The holding period applicable to a
 
                                       29
<PAGE>   142
 
Class B Share acquired through the use of the exchange privilege (discussed
below) shall be the holding period applicable to a Class B Share of such Fund
acquired other than through use of the exchange privilege. For purposes of
calculating the holding period applicable to a Class B Share of the Fund prior
to conversion, a Class B Share of the Fund issued in connection with an exercise
of the exchange privilege, or a series of exchanges, shall be deemed to have
been issued on the date on which the investor's order to purchase the exchanged
Class B Share was accepted or, in the case of a series of exchanges, when the
investor's order to purchase the original Class B Share was accepted.
 
  The conversion of Class B 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 services fee and transfer agency costs
with respect to Class B 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 Class B
Shares does not constitute a taxable event under federal income tax law. The
conversion of Class B Shares to Class A Shares may be suspended if such an
opinion is no longer available. In that event, no further conversions of Class B
Shares would occur, and Class B Shares might continue to be subject to the
higher aggregate distribution and service fees for an indefinite period.
 
- --------------------------------------------------------------------------------
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 the Fund's transfer agent receives payments for such shares.
However, shares become entitled to dividends on the day the Fund's transfer
agent 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.
 
                                       30

  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 information under the "Distributions" section of the
Account Application bound in this Prospectus or available from State Street Bank
and Trust Company, c/o National Financial Data Services, Van Kampen Merritt
Funds, P.O. Box 419001, Kansas City, MO 64141-6001 (the "Transfer Agent"). After
the Transfer Agent 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 to the Transfer Agent. This election may be made by telephone by
calling 1-800-341-2911 or in writing to the Transfer Agent. For inquiries
through Telecommunications Device for the Deaf (TDD), dial 1-800-772-8889,
during the hours of 7:30 a.m. to 4:00 p.m. Central Standard Time. If a
shareholder elects to change the method of distribution, such change will be
effective only with regard to distributions for which the record date is seven
or more business days after the Transfer Agent has received the request.
 
- --------------------------------------------------------------------------------
REDEMPTION OF SHARES
- --------------------------------------------------------------------------------
 
  WRITTEN REDEMPTION REQUEST. Shareholders may sell shares without charge (other
than, with respect to the CDSC Shares, any applicable contingent deferred sales
charge) at any time by mailing a written redemption request in proper form to
the Transfer Agent. This request should be sent to State Street Bank and Trust
Company, c/o National Financial Data Services, Van Kampen Merritt Funds, P.O.
Box 419001, Kansas City, MO 64141-6001. The request should indicate the number
of shares to be redeemed of a particular fund and the class designations of such
shares, identify the account number and be signed exactly as the shares are
registered. If the amount being redeemed is in excess of $50,000 or if the
redemption proceeds will be sent to an address other than the address of record,
the signature(s) must be guaranteed by a member firm of a principal stock
exchange, a commercial bank or trust company which is a member of the Federal
Deposit Insurance Corporation, a credit union or a savings association. The
guarantee must state the words "Signature Guaranteed" along with the name of the
granting institution. Shareholders should verify with the institution that it is
an eligible guarantor prior to signing. A guarantee from a notary public is not
acceptable. If certificates are held for the shares being redeemed, such
certificates must be sent and endorsed for transfer or accompanied by an
endorsed stock power. Share certificates should be sent by registered mail to
National Financial Data Services, 1004 Baltimore Avenue, Dwight Building, Sixth
Floor, Kansas City, MO 64105-1807. Shareholders will receive the net asset value
per share next computed after the Transfer Agent receives the redemption request
and certificates (if any) in proper form. Any applicable contingent deferred
sales charge with respect to CDSC Shares redeemed will be deducted from the
redemption proceeds prior to transmittal of such proceeds to the shareholder.

  TELEPHONE REDEMPTIONS. Shareholders may sell shares by calling the Fund at
1-800-341-2911 before 3:00 p.m. Central Standard Time to request a redemption by
the Fund. For inquiries through Telecommunications Device for the Deaf (TDD),
dial 1-800-772-8889, during the hours of 7:30 a.m. to 3:00 p.m. Central Standard
Time. There is a $500 minimum and a $1,000,000 maximum per request if the
redemption proceeds are to be mailed to the shareholder. If the redemption
proceeds are to be wired to a bank there is a minimum of $5,000 and a $1,000,000
maximum per request. Prior to redeeming shares by telephone the "Expedited
Telephone Redemption" section of either the Account Application or Expedited
Telephone Redemption and Exchange Request Form (the "Authorization") must be
completed and on file with the Transfer Agent. The signature(s) on the
Authorization must be guaranteed by a member firm of a principal stock exchange,
a commercial bank or trust company which is a member of the Federal Deposit
Insurance Corporation, a credit union or a savings association unless the
Authorization is completed at the time an account is originally established. The
guarantee must state the words "Signature Guaranteed" along with the name of the
granting institution. Shareholders should verify with the institution that it is
an eligible guarantor prior to signing. A guarantee from a notary public is not
acceptable. A redemption requested by telephone will be processed at the net
asset value next determined after receipt of the request. Any applicable
contingent deferred sales charge with respect to CDSC Shares redeemed will be
deducted from the redemption proceeds prior to transmittal of such proceeds to
the shareholder. The proceeds would then be made payable to the registered
shareowner(s) and mailed to the address registered on the account or wired to a
bank, as requested on the Authorizations. Shareholders cannot redeem shares by
telephone if stock certificates are held for those shares. This service is not
available with respect to shares held in an Individual Retirement Account for
which State Street Bank and Trust Company acts as custodian. In addition, this
service is not available with respect to shares purchased by check until 15 days
after purchase.
    
 
   
  By establishing the telephone redemption service, a shareholder authorizes the
Fund or the Transfer Agent to act upon the instructions of any person by
telephone to redeem shares for any account for which such service has been
authorized. The Fund, the Distributor, the Transfer Agent and National Financial
Data Services, Inc. ("NFDS") employ procedures reasonably believed to confirm
that instructions communicated by telephone are genuine. Such procedures include
requiring a person attempting to redeem shares by telephone to provide, on a
recorded line, the name on the account, a social security number or tax
identification number and such additional information as may be included in the
Authorization. In addition, a shareholder agrees that none of the Fund, the
Distributor, the Transfer Agent or National Financial Data Services will be
liable for any loss, liability, cost or expense arising out of any request,
including any fraudulent or unauthorized request. This service may be amended or
terminated at any time by the Transfer Agent or the Fund. If a shareholder is
unable to reach the Fund by telephone, he or she may redeem shares pursuant to
the procedures set forth above under the caption "Written Redemption Request."
During periods of extreme economic or market changes, it may be difficult for
investors to reach the Fund by telephone and to effect telephone redemptions.
    
 
                                       32

  REDEMPTION THROUGH DEALERS. Shareholders may sell shares (whether in
certificate or book-entry form) through their securities dealer, who will
telephone the request to the Distributor. Shareholders will receive the net
asset value next determined after such shareholder places the sell order. Any
applicable contingent deferred sales charge with respect to CDSC Shares redeemed
will be deducted from the redemption proceeds prior to transmittal of such
proceeds to the shareholder. It is the responsibility of the shareholder's
broker, dealer or financial intermediary to transmit the redemption order to the
Distributor. Because the Fund generally will determine net asset value once each
business day as of the close of business, sell orders placed through a
shareholder'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 shareholder's order to be fulfilled on the basis of the
net asset value to be determined that day. Any change in the redemption price
due to the failure of the Distributor to receive a sell order prior to such time
must be settled between the shareholder and the broker, dealer or financial
intermediary submitting the order. The Fund does not charge for this transaction
(other than any applicable contingent deferred sales charge). Shareholders must
submit a written redemption request in proper form to their securities dealer
within five business days after calling the dealer with the sell order. The
request should indicate the number of shares to be redeemed and the class
designation of such shares, identify the account number and the order or
confirmation number assigned to the trade and be signed by the shareholder
exactly as the shares are registered. If the amount of the redemption exceeds
$50,000 or if the redemption proceeds will be sent to an address other than the
address of record, signature(s) must be guaranteed by a member firm of a
principal stock exchange, a commercial bank or trust company which is a member
of the Federal Deposit Insurance Corporation, a credit union or a savings
association. The guarantee must state the words "Signature Guaranteed" along
with the name of the granting institution. Shareholders should verify with the
institution that it is an eligible guarantor prior to signing. A guarantee from
a notary public is not acceptable. If certificates are held for the shares being
redeemed, such certificates must be sent endorsed for transfer or accompanied by
an endorsed stock power. Certificates should be sent by registered mail to State
Street Bank and Trust Company, c/o National Financial Data Services, Van Kampen
Merritt Funds, 1004 Baltimore Avenue, Dwight Building, Sixth Floor, Kansas City,
MO 64105-1807. Shareholders whose shares are held in an Individual Retirement
Account ("IRA") for which State Street Bank and Trust Company acts as custodian
may not sell their shares through their securities dealers.
 
   
  REDEMPTION UPON DISABILITY. The Fund will waive the CDSC on Class B Share
redemptions following the disability of a Class B shareholder. An individual
will be considered disabled for this purpose if he or she meets the definition
thereof in Section 72(m)(7) of the Internal Revenue Code (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 proof as he or she may require, the Fund will
    
 
                                       33
<PAGE>   146
 
   
require satisfactory proof of disability before it determines to waive the CDSC
on Class B Shares.
    
 
   
  In cases of disability, the CDSC on Class B 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 applies to a total or partial redemption, but only to redemptions of
shares held at the time of the initial determination of disability.
    
 
  GENERAL. Whether shares are redeemed by the Fund or sold through a securities
dealer, a check for the proceeds (net of any required tax withholding and, with
respect to CDSC Shares, any applicable contingent deferred sales charge)
ordinarily will be mailed to shareholders or their dealer, as the case may be,
within seven calendar days after a redemption request or repurchase order and
share certificates (if any) are received in proper form as set forth above. Wire
transfers from the Fund of redemption proceeds, in the manner described above,
ordinarily will be transmitted to the shareholder within one business day. If
any shares are redeemed or repurchased shortly after purchase, the Fund will not
mail the proceeds until checks received for the purchase of shares have cleared,
which may take 10 days or more. The proceeds, of course, may be more or less
than the cost of the shares.
 
  The right of redemption or resale to the Fund may be suspended or the date of
payment postponed during any period when the New York Stock Exchange is closed
(other than customary weekend and holiday closings), when an emergency exists as
defined by rules and regulations of the SEC, or during any period when the SEC
has by order permitted such suspension or postponement.
 
  The Fund reserves the right to redeem any investment if the value of an
account falls below $500. Before the Fund makes such redemption it will provide
the shareholder with written notice and 30 days in which to make an additional
investment sufficient to increase the value of the account to at least $500.
 
- --------------------------------------------------------------------------------
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
 
                                       34
<PAGE>   147
 
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 sub-trust. 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.

                                       35
<PAGE>   148
 
overall management of the Fund's business affairs. The Fund will pay the Adviser
a fee equal to a percentage of the average daily net assets of the Fund as
follows:

  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 Investment Company Act, of the Adviser,
Van Kampen American Capital Distributors, Inc. or Van Kampen American Capital,
Inc.), the charges and expenses of independent accountants, legal counsel, any
transfer 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 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 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 trustees/directors, officers and employees to buy and sell
securities for their personal accounts subject to procedures designed to prevent
conflicts of interest including, in some instances, preclearance of trades.
 
   
  PORTFOLIO MANAGEMENT.  David C. Johnson, a First Vice-President of the
Adviser, is primarily responsible for the day-to-day management of the Fund's
portfolio. Mr. Johnson has been employed by the Adviser for the last five years.
    
 
- --------------------------------------------------------------------------------
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
 
                                       36
<PAGE>   149
 
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,
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.
- --------------------------------------------------------------------------------
THE 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 Investment
Company Act of 1940. 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, 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, 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. Brokers, dealers and
financial intermediaries that have entered into Selling Agreements with the
Distributor and sell shares of the Fund are referred to herein as "financial
intermediaries."
 
  CLASS A SHARES. The Fund may spend an aggregate amount up to 0.30% 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 financial intermediaries and in connection with the
maintenance of such shareholders' accounts. The Fund pays the Distributor the
lesser of the balance of the 0.30% not paid to such financial intermediaries or
the amount of the Distributor's actual distribution related expense.
 
                                       37
<PAGE>   150
 
  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 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 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
financial intermediary's customers. The Fund pays the Distributor the lesser of
the balance of 0.75% not paid to such 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 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 contingent deferred sales charge. 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. The Fund will disclose in its prospectus from
time to time the then current amount of any such unreimbursed expenses with
respect to each class of CDSC Shares expressed as a dollar amount and as a
percent of the Fund's total net assets. As of December 31, 1994, there were
$418,563 and $5,871 of unreimbursed distribution
    
 
                                       38
<PAGE>   151
 
   
expenses with respect to Class B Shares and Class C Shares, respectively,
representing 0.06% and 0.00% of the Fund's total net assets. 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 contingent deferred sales charges.
    
 
  Because the Fund is a sub-trust of the Trust, amounts paid to the Distributor
as reimbursement for expenses of one sub-trust of the Trust may indirectly
benefit the other funds which are sub-trusts 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 contingent deferred sales charge
applicable to a particular class of CDSC Shares to defray distribution related
expenses attributable to any other class of CDSC 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.
 
- --------------------------------------------------------------------------------
TAX STATUS
- --------------------------------------------------------------------------------
 
The following discussion reflects applicable federal income tax law, as of the
date of this Prospectus:
 
  FEDERAL INCOME TAXATION. The Fund has qualified and intends to continue to
qualify as a regulated investment company under Subchapter M of the Internal
Revenue Code of 1986, as amended (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 if it distributes each year to its
shareholders at least 90% of its net investment income (including tax-exempt
interest and other taxable income including net short-term capital gains, 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 to satisfy the 90%
distribution requirement. The Fund will not be subject to federal income tax on
any net capital gain distributed to its shareholders. As a sub-trust of a
Massachusetts business trust, the Fund will not be subject to any excise or
income taxes in Massachusetts as long as each qualifies as a regulated
investment company for federal income tax purposes. 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 for such year and at least 98% of its
capital gain net income (the latter of which is generally computed on the basis
of the one-year period ending on October 31 of such year), plus any required
distribution amounts that were not distributed in previous taxable years. For
purposes of the excise tax, any ordinary income or capital
 
                                       39
<PAGE>   152
 
gain net income retained by, and taxed in the hands of, the Fund will be treated
as having been distributed.
 
  If the Fund qualifies as a regulated investment company and satisfies the 90%
distribution requirement, and if, at the close of each quarter of the Fund's
taxable year, at least 50% of the total of the Fund's assets consists of
obligations exempt from federal income tax ("tax-exempt obligations"), the Fund
will be qualified to pay exempt-interest dividends to its shareholders to the
extent of its tax-exempt interest income (less expenses applicable thereto).
Exempt-interest dividends are excludable from a shareholder's gross income for
federal income tax purposes, but may be taxable distributions for state, local
and other tax purposes. Exempt-interest dividends are included, however, 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. Interest expense with respect to indebtedness incurred or continued by a
shareholder to purchase or carry shares of the Fund is not deductible to the
extent that such interest relates to exempt-interest dividends received from the
Fund.
 
  Distributions of the Fund's investment company taxable income (which does not
include tax-exempt interest income) are taxable to shareholders as ordinary
income whether received in shares or in cash. Shareholders who receive
distributions in the form of additional shares will have a basis for federal
income tax purposes in each such share equal to the value thereof on the
reinvestment date. Distributions of the Fund's net capital gain ("capital gains
dividends"), if any, are taxable to shareholders at the rates applicable to
long-term capital gains regardless of the length of time shares of the Fund have
been held by such shareholders. Distributions in excess of the Fund's earnings
and profits, such as distributions of principal, will first reduce the adjusted
tax basis of the shares held by the shareholders and, after such adjusted tax
basis is reduced to zero, will constitute capital gains to such shareholders
(assuming such shares are held as a capital asset). The Fund will inform
shareholders of the source and tax status of such distributions promptly after
the close of each calendar year. Distributions from the Fund will not be
eligible for the dividends received deduction for corporations.
 
  Exempt-interest dividends allocable to interest received by the Fund on
certain "private activity" obligations issued after August 7, 1986 will be
treated as interest on such obligations and thus will give rise to an item of
tax preference that will increase a shareholder's alternative minimum taxable
income. Unless otherwise provided in regulations, the portion of the Fund's
interest on such "private activity" obligations allocable to shareholders will
correspond to the portion of the Fund's total net tax-exempt income distributed
to shareholders. In addition, for corporations, alternative minimum taxable
income will be increased by a percentage of the amount by which a measure of
income that includes interest on tax-exempt obligations exceeds the amount
otherwise determined to be the alternative minimum taxable income. Accordingly,
investment in the Fund may cause such shareholders to be subject to (or result
in an increased liability under) the alternative minimum tax.
 
                                       40
<PAGE>   153
 
  Exempt-interest dividends will not be tax-exempt to the extent made to any
shareholder who is a "substantial user" of the facilities financed by tax-exempt
obligations held by the Fund or "related persons" of such substantial users.
 
  Redemption or resale of shares of the Fund will be a taxable transaction for
federal income tax purposes. Redeeming shareholders will recognize gain or loss
in an amount equal to the difference between their basis in such redeemed shares
of the Fund 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 generally be long-term
if such shareholders have held shares for more than one year. Any loss realized
on shares held for six months or less will be disallowed to the extent of any
exempt-interest dividends received with respect to such shares. If such loss is
not entirely disallowed, it will be treated as a long-term capital loss to the
extent of any capital gains dividends received with respect to such shares.
 
  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 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 closed out), 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
requirement for avoiding income 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.
 
  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 federal income taxes. In order to
generate sufficient cash to make distributions necessary to satisfy the 90%
distribution requirement and avoid federal income 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 to shareholders.
 
  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 gross income be derived from the disposition of securities
held for less than three months.
 
  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 a month and paid in January of the following
year will be treated as having been distributed by the Fund and received by the
shareholders on the December 31 of the year in which the dividend was declared.
In addition, certain other distributions made after the close of a taxable year
of the Fund may be "spilled back" and treated as
 
                                       41
<PAGE>   154
 
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 is actually made.
 
  The Fund is required in certain circumstances to withhold 31% of taxable
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.
 
  GENERAL.  The federal income tax discussion set forth above is for general
information only. Prospective investors should consult their tax advisers
regarding the specific federal tax consequences of holding and disposing of
shares, as well as the effects of state, local and foreign tax laws.
 
- --------------------------------------------------------------------------------
SHAREHOLDER PROGRAMS
- --------------------------------------------------------------------------------
 
   
  SHARE CERTIFICATES.  As a rule, the Fund will not issue share certificates.
Upon written or telephone request to the Fund, however, 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. In addition, if such certificates are lost the shareholder must
write to State Street Bank and Trust Company, c/o National Financial Data
Services, P.O. Box 419001, Kansas City, MO 64141-6001, Attn: Van Kampen Merritt
Funds, requesting an "affidavit of loss" and to obtain a Surety Bond in a form
acceptable to the Transfer Agent. On the date the letter is received the
Transfer Agent will calculate no more than 2.00% of the net asset value of the
issued shares, and bill the party to whom the certificate was mailed.
    
 
   
  SYSTEMATIC WITHDRAWAL PROGRAM.  If a shareholder's Class A Shares account or
Class B Shares account is valued at $10,000 or more, such shareholder's
dividends are being reinvested and the shareholder's account is held in the Open
Account Program, a requested dollar amount may be paid from such account to any
person monthly, quarterly, semiannually or annually. The minimum amount that may
be withdrawn each period is $50; withdrawals will be made on the seventh
business day of the month in which they are scheduled to occur. Depending upon
the size of the payments requested and the fluctuations in the net asset value
of the shares redeemed, redemptions for the purpose of making such payments may
reduce or even exhaust the amounts in such account. If an investor acquires
additional shares of the Fund after joining the Systematic Withdrawal Program,
the investor must inform the Fund if he or she wants the new shares to be
subject to the Systematic Withdrawal Program by telephoning the Fund at
1-800-341-2911.
    
 
   
  With respect to redemptions of Class B Shares made pursuant to the Systematic
Withdrawal Program, an investor may annually redeem up to 12% of the net asset
value of the investor's initial investment in Class B Shares or, if the investor
does not join the program on the date of his or her initial investment, the net
asset value of the investor's
    
 
                                       42
<PAGE>   155
 
   
Class B Shares on the date the investor elects to participate in the Systematic
Withdrawal Program. The Fund will waive the contingent deferred sales charge
applicable to Class B Shares redeemed pursuant to the Fund's Systematic
Withdrawal Program.
    
 
  It will ordinarily be disadvantageous to purchase shares (except through
reinvestment of distributions) while participating in a systematic withdrawal
program because a shareholder will be paying a sales charge, or will become
subject to a contingent deferred sales charge, in order to purchase shares at
the same time that shares are being redeemed upon which a sales charge may
already have been paid. Therefore, the Fund will not knowingly permit a
shareholder to make additional investments in shares of less than $5,000 if at
the same time such shareholder is making systematic withdrawals at a rate
greater than the distribution being paid on such shareholder's shares. The Fund
reserves the right to amend or terminate the systematic withdrawal program on
thirty days' notice, and a shareholder may withdraw from the program at any
time.
 
  EXCHANGE PRIVILEGE.  Any Class A Shares of the Fund which have been registered
in a shareholder's name for at least 15 days will be able to be exchanged for
ISC Shares of other Van Kampen Merritt mutual funds distributed by the
Distributor that offer an exchange privilege. Under the exchange privilege, the
Fund will offer to exchange its Class A Shares for ISC Shares on the basis of
relative net asset value per share. Any ISC Shares exchanged into the Fund that
have been charged a sales load lower than the sales load applicable to Class A
Shares of the Fund will be charged the applicable sales load differential upon
exchange. ISC Shares of the Van Kampen Merritt Money Market Fund and Van Kampen
Merritt Tax Free Money Fund which have not previously been charged a sales load
(except for shares purchased via the reinvestment option) will be charged the
applicable sales load upon exchange into the Fund.
 
  Class B Shareholders of the Fund may exchange their Class B Shares
("Outstanding Class B Shares") for Class B Shares of other Van Kampen Merritt
mutual funds sponsored by the Distributor ("New Class B Shares") on the basis of
relative net asset value per Class B Share, without the payment of any
contingent deferred sales charge that might otherwise be due on redemption of
the Outstanding Class B Shares. Class B Shares of a fund acquired through use of
the exchange privilege will be 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.
 
   
  Class C Shares of the Fund are exchangeable for Class C Shares of other Van
Kampen Merritt mutual funds distributed by the Distributor on the same terms set
forth in the preceding paragraph with respect to Class B Shares, except that
Class C Shares do not convert to Class A Shares. The exchange privilege with
respect to any Van Kampen Merritt money market fund sponsored by the Distributor
is not available for Class C Shareholders.
    
 
   
  In order to qualify for the exchange privilege, it is required that the shares
being exchanged have a net asset value of at least $1,000 (unless prior approval
has been obtained from the Fund). Shareholders will be able to effect an
exchange by telephone by calling the Fund at 1-800-341-2911 prior to 3:00 p.m.
Central Standard Time and
    
 
                                       43

requesting the exchange. For inquiries through Telecommunications Device for the
Deaf (TDD), dial 1-800-772-8889, during the hours of 7:30 a.m. to 3:00 p.m.
Central Standard Time. The exchange will be processed at the net asset value
next determined after receipt of such request. By utilizing the telephone
exchange service, a shareholder authorizes the Fund or the Transfer Agent to act
upon the instructions of any person by telephone to exchange shares from any
account for which such service has been authorized to any identically registered
account(s) with any Van Kampen Merritt fund distributed by the Distributor that
offers an exchange privilege. In addition, a shareholder agrees that none of the
Fund, the Distributor, the Transfer Agent or National Financial Data Services
("NFDS") will be liable for any loss, liability, cost or expense arising out of
any request, including any fraudulent request. The staff of the SEC currently is
reviewing its position with respect to such agreements. This service may be
amended or terminated at any time by the Transfer Agent or the Fund. If a
shareholder has certificates for any shares being exchanged, such certificates
must be surrendered prior to the exchange in the same manner as in redemption of
such shares. See "Redemption of Shares -- Telephone Redemptions". Any shares
exchanged between the Fund and any of the other funds will begin earning
dividends on the next business day after the exchange is effected. 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.
    
 
  An exchange between Van Kampen Merritt funds pursuant to the exchange
privilege is treated as a sale for federal income tax purposes and, depending
upon the circumstances, a short- or long-term capital gain or loss may be
realized.
 
  The exchange privilege may be modified or terminated at any time, subject to
the requirement that the Fund give prominent notice thereof at least 60 days
prior to the effective date of the modification or termination in certain
circumstances. The Fund reserves the right to limit the number of times a
shareholder may exercise the exchange privilege.
 
  AUTOMATED MULTIPLE ACCOUNT SHAREHOLDER SERVICES (AMASSSM).
 
   
  1. 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
the Transfer Agent 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 the Transfer
Agent.
    
 
                                       44
<PAGE>   157
 
  2. Automated Dividend Programs.  The Fund will, upon the election of a
shareholder, automatically invest distributions from a shareholder's account
directly into a shareholder's bank account.
 
   
  3. Dividend Diversification.  Monthly distributions and any net long-term
capital gain distributions to a shareholder's account may be invested in the
same class of shares of any other Van Kampen Merritt mutual fund distributed by
the Distributor at the then current net asset value, WITHOUT A SALES CHARGE,
upon election by a shareholder. This election may be made on the account
application bound in this Prospectus, by written notice to the Transfer Agent or
by calling the Fund directly at 1-800-341-2911, during the hours of 7:00 a.m. to
7:00 p.m. Central Standard Time. For inquiries through Telecommunications Device
for the Deaf (TDD), dial 1-800-772-8889. In order to qualify for this privilege,
a shareholder must have established an account in the other mutual fund prior to
electing this privilege. This privilege may be modified or terminated by the
Fund at any time.
    
 
  4. Easy Account Savings Enhancement Plan (EASESM). Once a shareholder has
opened an account with the minimum $1,000 investment, the automatic investment
option may be utilized to make regular electronic monthly investments of $100 or
more into such shareholder's account with the Fund. In order to utilize this
option, a shareholder must fill out and sign the appropriate section of the
application attached to this Prospectus or the EASESM application which is
available from the Transfer Agent, the Fund, such shareholder's broker or dealer
or the Distributor. Once the Transfer Agent has received this application, such
shareholder's checking account at his or her designated local bank will be
debited each month in the amount authorized by such shareholder to purchase
shares of the Fund. Once enrolled in the EASESM program, a shareholder may
change the monthly amount or terminate participation at any time by writing or
calling the Transfer Agent. Shareholders in the EASESM program will receive a
confirmation of these transactions from the Fund monthly, and their regular bank
account statements will show the debit transaction each month.
 
  By electing to utilize any of the foregoing services, a shareholder authorizes
the Transfer Agent or its agent to act upon the instructions indicated in the
appropriate section of the Application in performing such services by either
withdrawing funds for deposit in the Fund pursuant to the EASESM Plan or
depositing distributions and redemptions in the bank account indicated by the
voided check or deposit slip accompanying the shareholder's election and/or by
depositing the shareholder's distributions in the Van Kampen Merritt fund
account indicated. A shareholder also agrees that neither the Fund, the
Distributor, the Transfer Agent nor NFDS will be liable for any loss, liability,
cost or expense arising out of any request, including any fraudulent request.
This service may be amended or terminated at any time by the Transfer Agent or
by the Fund.
 
  REINSTATEMENT PRIVILEGE. A shareholder who has redeemed Class A Shares or
Class B Shares may, within 120 days, repurchase Class A Shares of the Fund, or
shares of other Van Kampen Merritt mutual funds distributed by the Distributor,
in an amount of at least $500 and not exceeding the redemption proceeds
received, at a purchase price equal to the net asset value next determined after
the reinstatement request is received by the Transfer Agent or the Distributor.
A Class C Shareholder who has redeemed shares of the Fund
 
                                       45

may repurchase Class C Shares of the Fund, or shares of other Van Kampen Merritt
mutual funds distributed by the Distributor with credit given for any contingent
deferred sales charge paid upon such redemption.
 
- --------------------------------------------------------------------------------
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., Business Week, Forbes or other industry 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 and/or return.
In addition, from time to time, the Fund may utilize sales literature that
includes hypotheticals.
 
  Please consult the Statement of Additional Information for more information
regarding the Fund's performance.

opened for each shareholder on the Fund's books and shareholders will receive a
confirmation of the opening of the account. Shareholders will receive monthly
statements giving details of all activity in their account(s) during the quarter
and will also receive a statement whenever an investment or withdrawal is made
in or from their account. Information for federal income tax purposes will be
provided at the end of the year. Such statements will present separately
information with respect to each class of the Fund's shares. It is expected that
the transfer agency costs attributable to the Class B Shares and Class C Shares
will be higher than the transfer agency costs attributable to the Class A
Shares.
 
- --------------------------------------------------------------------------------
DESCRIPTION OF SHARES OF THE FUND
- --------------------------------------------------------------------------------
 
  The Fund is a sub-trust of the Van Kampen Merritt Tax Free Fund, a
Massachusetts business trust organized August 15, 1985 (the "Trust"). Shares of
the Trust entitle their holders to one vote per share; however, separate votes
are taken by each sub-trust on matters affecting an individual sub-trust.
 
  The authorized capitalization of the Fund consists of an unlimited number of
shares of beneficial interest, without 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 "The
Distribution and Service Plans."
 
  Pursuant to an order of the SEC, 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 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 Class B Shareholders 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 a majority of the shares present and voting at
such meeting. The Trust will assist such holders in communicating with other
shareholders of the Fund to the extent required by the Investment Company Act of
1940. More detailed information concerning the Trust is set forth in the
Statement of Additional Information.

municipal securities rated investment grade at the time of investment. There is
no assurance that the Fund will achieve its investment objective. The Fund is a
separate sub-trust of Van Kampen Merritt Tax Free Fund, a Massachusetts business
trust (the "Trust").

                             THE FUND AND THE TRUST
 
   
  The Fund is a separate sub-trust of the Trust, an open-end diversified
management investment company. At present, the Fund, Van Kampen Merritt Insured
Tax Free Income Fund, Van Kampen Merritt Tax Free High Income Fund, Van Kampen
Merritt California Insured Tax Free Fund, Van Kampen Merritt Limited Term
Municipal Income Fund, Van Kampen Merritt Florida Insured Tax Free Income Fund,
Van Kampen Merritt New Jersey Tax Free Income Fund, and Van Kampen Merritt New
York Tax Free Income Fund have been organized as sub-trusts of the Trust and
have commenced investment operations. Van Kampen Merritt California Tax Free
Income Fund, Van Kampen Merritt Michigan Tax Free Income Fund, Van Kampen
Merritt Missouri Tax Free Income Fund and Van Kampen Merritt Ohio Tax Free
Income Fund have been organized as sub-trusts of the Trust but have not yet
commenced investment operations. Other sub-trusts may be organized and offered
in the future.
    
 
  The Trust is an unincorporated business trust established under the laws of
the Commonwealth of Massachusetts by a Declaration of Trust dated August 15,
1985. The Declaration of Trust permits the Trustees to issue an unlimited number
of full and fractional shares in separate sub-trusts. Each share represents an
equal proportionate interest in the assets of the sub-trust with each other
share in such sub-trust and no interest in any other sub-trust. No sub-trust is
subject to the liabilities of any other sub-trust. The Declaration of Trust
provides that shareholders are not liable for any liabilities of the Trust or
any of its sub-trusts, requires inclusion of a clause to that effect in every
agreement entered into by the Trust or any of its sub-trusts 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 sub-trust on matters affecting an individual
sub-trust. For example, a change in investment policy for a sub-trust would be
voted upon by shareholders of only the sub-trust involved. 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 a majority of the shares present and voting at
such meeting.
 
  The Trustees may amend the Declaration of Trust (including with respect to any
sub-trust) in any manner without shareholder approval, except that the Trustees
may not adopt any amendment adversely affecting the rights of shareholders of
any sub-trust without approval by a majority of the shares of each affected
sub-trust 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 issuer or, if, as a result, the Fund would hold
      more than 10% of the outstanding voting securities of an issuer.
 
   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
 
                                       B-2
<PAGE>   164
 
      market; however, the Fund will not invest more than 25% of its assets in
      industrial development bonds in a single industry.)
 
   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.
 
   9. Invest in securities of other investment companies, except as part of a
      merger, consolidation or other acquisition and except that the Fund may
      invest up to 10% of its assets in tax-exempt investment companies that
      invest in securities rated comparably to those the Fund may invest in so
      long as the Fund does not own more than 3% of the outstanding voting stock
      of any tax-exempt investment company or securities of any tax-exempt
      investment company aggregating in value more than 5% of the total assets
      of the Fund.
 
  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 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 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 outstanding 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 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
 
                                       B-4
<PAGE>   166
 
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, 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.
 
  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
 
                                       B-5
<PAGE>   167
 
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 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.
 
                                       B-6
<PAGE>   168
 
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
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.
 
                                       B-7
<PAGE>   169
 
  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-8
<PAGE>   170
 
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 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
 
                                       B-9
<PAGE>   171
 
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 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,
 
                                      B-10
<PAGE>   172
 
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 Investment Company Act of 1940 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 high-grade securities
at least equal to the current
 
                                      B-11
<PAGE>   173
 
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 high-grade
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, high-grade assets 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 high-grade 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 Internal Revenue 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 Standard & Poor's 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 balance, as
    B         predominantly speculative with respect to capacity to pay interest and repay
    CCC       principal. 'BB' indicates the least degree of speculation and 'C' the highest.
    CC        While such debt will likely have some quality and protective characteristics,
    C         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-13
<PAGE>   175
 
<TABLE>
    <S>       <C>
    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.
 
    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>

<PAGE>   176
 
   
<TABLE>
    <S>       <C>
    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.
</TABLE>
    
 
  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'.
 
    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-15
<PAGE>   177
 
     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.
 
    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.
 
    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.
</TABLE>
 
     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 senior debt obligations which have an original maturity
     not exceeding one year. Obligations relying upon support mechanisms such as
     letters-of-credit and bond 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 (or supporting institutions) have a superior
        ability for repayment of senior short-term debt obligations.
 
             Issuers rated Prime-2 (or supporting institutions) have a strong
        ability for repayment of senior short-term debt obligations.
 
                                      B-17
<PAGE>   179
 
             Issuers rated Prime-3 (or supporting institutions) have an
        acceptable ability for repayment of senior short-term debt obligations.
 
          Issuers rated Not Prime do not fall within any of the Prime rating
     categories.

  Each of the foregoing trustees of the Fund acts as a trustee for other
investment companies advised by the Adviser, and each of the foregoing officers
holds the same positions with other investment companies advised by the Adviser.
 
   
  The compensation of the officers and trustees who are affiliated persons (as
defined in the 1940 Act) of the Adviser, Van Kampen American Capital
Distributors, Inc. or Van Kampen American Capital, Inc. is paid by the
respective entity. The Fund pays the compensation of all other officers and
trustees of the Fund. During the next year, the Fund expects to pay trustees who
are not affiliated persons of the Adviser, Van Kampen American Capital
Distributors, Inc. or Van Kampen American Capital Companies, Inc. $2,500 per
year, and $250 per meeting of the Board of Trustees, plus expenses. Under the
Fund's retirement plan, trustees who are not affiliated with the Adviser, Van
Kampen American Capital Distributors, Inc. or Van Kampen American Capital, Inc.,
have at least ten years of service and retire at or after attaining the age of
60, are eligible to receive a retirement benefit equal to the annual retainer
for each of the ten years following such trustee's retirement. Under certain
conditions, reduced benefits are available for early retirement. Under the
Fund's deferred compensation plan, a trustee who is not affiliated with the
Adviser, Van Kampen American Capital Distributors, Inc. or Van Kampen American
Capital, Inc. can elect to defer receipt of all or a portion of the trustee's
fees earned by such trustee until such trustee's retirement. The deferred
compensation earns a rate of return determined by reference to the Fund or other
Van Kampen Merritt mutual funds advised by the Adviser as selected by the
trustee. To the extent permitted by the Investment Company Act, the Fund may
invest in securities of other Van Kampen Merritt mutual funds advised by the
Adviser 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.

(1) Messrs. Merritt and McDonnell, Trustees of each Fund during fiscal year
    1994, are affiliated persons of the Adviser and are not eligible for
    compensation or retirement benefits from the Funds.
    
 
   
(2) The Registrant is Van Kampen Merritt Tax Free Fund (the "Trust") which
    currently is comprised of 8 sub-trusts, including the Fund. The amounts
    shown in this column are accumulated from the Aggregate Compensation of each
    of these 8 sub-trusts during such sub-trust's last completed fiscal year
    prior to the date of this Statement of Additional Information. Beginning in
    October 1994 each Trustee, except Messrs. Gaughan and Whalen, began
    deferring his entire aggregate compensation paid by the Fund. The total
    combined amount of deferred compensation (including interest) accrued with
    respect to each Trustee as of December 31, 1994 is as follows: Mr. Kennedy
    $14,737; Mr. Miller $14,553; Mr. Nelson $14,737 and Mr. Robinson $13,725.
    
 
   
(3) The Retirement Plan commenced as of August 1, 1994 for the Fund. As of the
    end of the Fund's 1994 fiscal year, no amounts had been accrued for
    retirement benefits because such amounts were either zero or considered to
    be immaterial to the net assets of the Fund at such time. During the Fund's
    1995 fiscal year, the Fund will accrue amounts for retirement benefits and
    include an amount, if any, for such Fund's 1994 fiscal year.

(4) This is the estimated annual benefits payable per year for the 10-year
    period commencing in the year of such Trustee's retirement by a Fund
    assuming: the Trustee has 10 or more years of service on the Board of the
    Fund, retires at or after attaining the age of 60 and the annual retainer in
    the year prior to the Trustee's retirement is $2,500. Trustees retiring
    prior to the age of 60 or with fewer than 10 years of service for the Fund
    may receive reduced retirement benefits from such Fund.
    
 
   
(5) The Fund Complex consists of 20 mutual funds advised by the Adviser. The
    amounts shown in this column are accumulated from the Aggregate Compensation
    of each of these 20 mutual funds in the Fund Complex during each fund's last
    completed fiscal year prior to the date of this Statement of Additional
    Information. The Adviser also serves as investment adviser for other mutual
    funds and closed-end investment companies; however, with the exception of
    Messrs. Merritt, McDonnell and Whalen, such mutual funds and closed-end
    investment companies do not have the same trustees as the Fund Complex.
    Combining the Fund Complex with other mutual funds and investment companies
    advised by the Adviser, Mr. Whalen received Total Compensation of $161,850.
    
 
   
  As of April 13, 1995, the trustees and officers as a group own less than 1% of

                     INVESTMENT ADVISORY AND OTHER SERVICES
    
 
INVESTMENT ADVISORY AGREEMENT
 
  Van Kampen Merritt Investment Advisory Corp. (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's principal office is
located at One Parkview Plaza, Oakbrook Terrace, Illinois 60181.
 
  The Adviser is a wholly-owned subsidiary of Van Kampen American Capital, Inc.,
which in turn is a wholly-owned subsidiary of VK/AC Holding, Inc. VK/AC Holding,
Inc. is controlled, through the ownership of a substantial majority of its
common stock, by The Clayton & Dubilier Private Equity Fund IV Limited
Partnership ("C&D L.P."), a Connecticut limited partnership, C&D L.P. is managed
by Clayton, Dubilier & Rice, Inc., a New York based private investment firm. The
General Partner of C&D L.P. is Clayton & Dubilier Associates IV Limited
Partnership ("C&D Associates L.P."). The general partners of C&D Associates L.P.
are Joseph L. Rice, III, B. Charles Ames, William A. Barbe, Alberto Cribiore,
Donald J. Gogel, Leon J. Hendrix, Jr., Hubbard C. Howe and Andrall E. Pearson
each of whom is a principal of Clayton, Dubilier & Rice, Inc. In addition,
certain officers, directors and employees of Van Kampen American Capital, Inc.
own, in the aggregate, not more than 6% of the common stock of VK/AC Holding,
Inc. and have the right to acquire, upon the exercise of options, approximately
an additional 10% of the common stock of VK/AC Holding, Inc.
 
  The investment advisory agreement dated February 17, 1993, and approved by
shareholders of the Fund at a meeting held on January 14, 1993, 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
 
                                      B-21
<PAGE>   183
 
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 sub-trust, 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 sub-trust (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, 1994, 1993 and 1992, the Fund recognized
advisory expenses of $3,475,616, $2,578,871 and $1,315,431, respectively.
    
 
OTHER AGREEMENTS
 
  SUPPORT SERVICES AGREEMENT.  Under a support services agreement with the
Distributor the Fund receives support services for shareholders, including the
handling of all written and telephonic communications, except initial order
entry and other distribution related communications. Upon entering into such
agreement, the Fund realized a reduction in the fee which would have been paid
to the Transfer Agent if the Transfer Agent had provided such services. Payment
by the Fund for such services is made on cost basis for the employment of the
personnel and the equipment necessary to render the support services. The Fund,
and the other Van Kampen Merritt mutual funds distributed by the Distributor,
share such costs proportionately among themselves based upon their respective
net asset values.
 
   
  For the years ended December 31, 1994, 1993 and 1992, the Fund recognized
expenses of approximately $334,800, $275,030 and $158,860, respectively,
representing the Distributor's cost of providing certain support services.
    
 
   
  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 Merritt mutual funds
distributed by the Distributor 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 Merritt funds based proportionally on
their respective net assets.
    
 
   
  For the years ended December 31, 1994, 1993 and 1992, the Fund recognized
expenses of approximately $18,250, $16,306 and $7,960, respectively,
representing the Adviser's cost of providing accounting services.
    
 
  LEGAL SERVICES AGREEMENT.  The Fund has entered into a Legal Services
Agreement pursuant to which Van Kampen American Capital, Inc. provides legal
services, including without limitation: accurate maintenance of
 
                                      B-22
<PAGE>   184
 
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 Fund. 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. The Fund, and the other Van Kampen Merritt mutual funds
distributed by the Distributor, share one half (50%) of such costs equally. The
remaining one half (50%) of such costs are allocated to specific funds based on
specific time allocations, or in the event services are attributable only to
types of funds (i.e. closed-end or open-end), the relative amount of time spent
on each type of fund and then further allocated between funds of that type based
upon their respective net asset values.
 
   
  For the years ended December 31, 1994, 1993 and 1992, the Fund recognized
expenses of approximately $21,950, $21,500 and $7,200, respectively,
representing Van Kampen American Capital, Inc.'s cost of providing legal
services.
    
 
CUSTODIAN AND INDEPENDENT AUDITORS
 
  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 auditors for the Fund are KPMG Peat Marwick LLP, Chicago,
Illinois. The selection of independent auditors 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
 
                                      B-23
<PAGE>   185
 
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 sub-trust.
 
   
  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 each of its sub-trusts, including the Fund, will be treated as
separate corporations for income tax purposes. The Fund may be subject to tax if
it fails to distribute net capital gains, or if its annual distributions, as a
percentage of its income, are less than the distributions required by tax laws.
 
                                THE DISTRIBUTOR
 
  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 Van Kampen American Capital, Inc., which is a subsidiary of
VK/AC Holding, Inc., a Delaware corporation that is controlled through an
ownership of a substantial majority of its common stock, by The Clayton &
Dubilier Private Equity Fund IV Limited Partnership ("C & D L.P."), a
Connecticut limited partnership. In addition, certain officers, directors and
employees of Van Kampen American Capital, Inc., and its subsidiaries own, in the
aggregate not more than 6% of the common stock of VK/AC Holding, Inc. and have
the right to acquire, upon the exercise of options, approximately an additional
10% of the common stock of VK/AC Holding, Inc. C & D L.P. is managed by Clayton,
Dubilier & Rice, Inc. Clayton & Dubilier Associates IV Limited Partnership ("C &
D Associates L.P.") is the general partner of C & D L.P. 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.
 
  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,
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 banks 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
 
                                      B-24
<PAGE>   186
 
and banks 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 and/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 sub-trust, 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 year ended December 31, 1994, the Fund has recognized expenses under
the Plans of $1,626,311, $1,662,702 and $41,554 for the Class A Shares, Class B
Shares and Class C Shares, respectively, of which $1,357,846 and $408,661
represent payments to financial intermediaries under the Selling Agreements for
Class A Shares and Class B Shares, respectively. For the year ended December 31,
1994, the Fund has reimbursed the Distributor $212,577 and $55,751 for
advertising expenses, and $40,262 and $26,873 for compensation of the
Distributor's sales personnel for the Class A Shares and Class B Shares,
respectively.
    
 
                                 LEGAL COUNSEL
 
  Counsel to the Fund is Skadden, Arps, Slate, Meagher & Flom, Chicago,
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. 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.
    
 
                                      B-25
<PAGE>   187
 
  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 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.

Van Kampen Merritt Municipal Income Fund

- --------------------------------------------------------------------------------
Notes to Financial Statements
December 31, 1994
- --------------------------------------------------------------------------------

1. Significant Accounting Policies

Van Kampen Merritt Municipal Income Fund (the "Fund") was organized as a
sub-trust of the Van Kampen Merritt Tax Free Fund, a Massachusetts business
trust, and is registered as a diversified open-end management investment company
under the Investment Company Act of 1940, as amended. The Fund commenced
investment operations on August 1, 1990. On August 24, 1992, the Fund commenced
the distribution of its Class B shares. The distribution of the Fund's Class C
shares, which were initially introduced as Class D shares and subsequently
renamed Class C shares on March 7, 1994, commenced on August 13, 1993. The
distribution of the Fund's fourth class of shares, Class D shares, commenced on
March 14, 1994.

The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements.


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 less than 60 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" and "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, 1994, 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.

D. Organizational Expenses and Initial Registration Costs-The Fund has
reimbursed Van Kampen American Capital Distributors, Inc. or its affiliates
("VKAC") for costs incurred in connection with the Fund's organization and
initial registration in the amount of $152,425. These costs are being amortized
on a straight line basis over the 60 month period ending July 31, 1995. 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 and initial
registration costs 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 the loss and offset such losses against any future realized capital
gains. At December 31, 1994, the Fund had an accumulated capital loss
carryforward for tax purposes of $18,151,198. Of this amount, $10,452,715 and
$7,698,483 will expire on December 31, 2001 and 2002, respectively. Net realized
gains or losses may differ for financial and tax reporting purposes primarily as
a result of the deferral of post October 31 losses and the capitalization of
reorganization and restructuring costs for tax purposes.


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. 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.


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:

Over $500 million....  .45 of 1%

</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, 1994, the Fund recognized expenses of
approximately $375,000 representing VKAC's cost of providing accounting, legal
and certain shareholder services to the Fund.

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

Class B, C and D shares are offered without a front end sales charge, but are
subject to a contingent deferred sales charge (CDSC). The CDSC will be imposed
on most redemptions made within six years of the purchase for Class B and one
year of the purchase for Classes C and D as detailed in the following schedule.
The Class B, C and D shares bear the expense of their respective deferred sales
arrangements, including higher distribution and service fees and incremental
transfer agency costs.

4. Investment Transactions

notes and reorganization and restructuring costs, for the year ended December
31, 1994, were $541,728,813 and $708,214,680, 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 for exercised option contracts where
the recognition of gain or loss is postponed until the disposal of the security
underlying the option 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.

</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.

The fluctuation in market value of the contracts is settled daily through a cash
margin account. Realized gains and losses are recognized when the contracts are
closed or expire.

Transactions in futures contracts for the year ended December 31, 1994, 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. 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.

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. Insured municipal securities in which the California Insured Fund
may invest include conventional fixed-rate municipal securities, variable rate
municipal securities and other types of municipal securities described herein.
See "Municipal Securities." All of the municipal securities in the California
Insured Fund's portfolio will be insured by AMBAC Indemnity Corporation or by
other municipal bond insurers whose claims-paying ability is rated "AAA" by
Standard & Poor's Ratings Group on the date of purchase.
 
    Van Kampen American Capital Investment Advisory Corp. is the investment
adviser for both of the Insured Fund and the California Insured Fund
(collectively, the "Funds"). There is no assurance that the Funds will achieve
their respective investment objectives. This Prospectus sets forth certain
information about the Funds that a prospective investor should know before
investing in either of the Funds. Please read it carefully and retain it for
future reference. Each Fund's address is One Parkview Plaza, Oakbrook Terrace,
Illinois 60181, and each Fund's telephone number is (800) 225-2222, ext. 6504.
 
    The Funds currently offer three classes of shares (the "Alternative Sales
Arrangements") 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 (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"). 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.
 
   
    Each class of shares pays ongoing distribution and service fees at an
aggregate annual rate of (i) for Class A Shares, up to 0.30% of a Fund's average
daily net assets attributable to the Class A Shares, (ii) for Class B Shares, up
to 1.00% of a Fund's average daily net assets attributable to the Class B
Shares; and (iii) for Class C Shares up to 1.00% of the Fund's average daily net
assets attributable to the Class C Shares. Investors should understand that the
purpose and function of the deferred sales charge and the distribution and
service fees with respect to the Class A Share accounts over $1 million, Class B
Shares and the Class C Shares are the same as those of the initial sales charge
and distribution and service fees with respect to the Class A Share accounts
below $1 million. Each share of a Fund represents an identical interest in the
investment portfolio of such Fund and has the same rights, except that (i) each
class of shares bears those distribution fees, service fees and administrative
expenses applicable to the respective class of shares as a result of its sales
arrangements, which will cause the different classes of shares to have different
expense ratios and to pay different rates of dividends, (ii) each class has
exclusive voting rights with respect to those provisions of such Fund's Rule
12b-1 distribution plan which relate only to such class and (iii) the classes
have different exchange privileges. Class B Shares of each Fund automatically
will convert to Class A Shares of the respective Fund after the number of years
set forth herein, in the circumstances and subject to the qualifications
described in this Prospectus. See "Purchasing Shares of the Fund."

                               PROSPECTUS SUMMARY
- --------------------------------------------------------------------------------
 
   
THE FUNDS  The Van Kampen Merritt Insured Tax Free Income Fund and Van Kampen
Merritt California Insured Tax Free Fund (each a "Fund" and collectively the
"Funds") each is a separate diversified sub-trust of Van Kampen Merritt Tax Free
Fund, an open-end, diversified management investment company organized as a
Massachusetts business trust. See "The Funds."
    
 
INVESTMENT OBJECTIVES AND POLICIES  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."
 
  Municipal securities in which 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."
 
INSURANCE  Each municipal security in the portfolio of the Insured Fund and the
California Insured Fund is insured as to the timely payment of principal and
interest under one or more policies obtained by the issuer or purchased by such
Funds. No representation is made as to the ability of any insurer to perform its
obligations. See "Insurance."
 
ALTERNATIVE SALES ARRANGEMENTS  The Alternative Sales Arrangements permit an
investor to choose the method of purchasing shares that is more beneficial to
the
 
                                        4

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 Examples" sets forth examples of the charges
applicable to each class of shares.
 
   
  The Funds 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.
    
 
  The minimum initial investment with respect to the Class A Shares, Class B
Shares and Class C Shares is $1,000. The minimum subsequent investment with
respect to each class of shares is $100.
 
   
  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 0.30% 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 contingent deferred sales charge.
    
 
  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 contingent
deferred sales charge 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 contingent deferred sales charge 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 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 the Insured Fund automatically will convert to Class A Shares
of the Insured Fund seven years after the end of the calendar month in which the
investor's order to purchase was accepted. Class B Shares of the California
Insured Fund automatically will convert to Class A Shares of the California
Insured Fund six years after the end of the calendar month in which the
investor's order to purchase was accepted.

<PAGE>   213
 
  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 contingent deferred sales charge
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.
 
   
INVESTMENT ADVISER AND ADVISORY FEE  Van Kampen American Capital Investment
Advisory Corp. (the "Adviser") is the investment adviser for both of the Funds.
The annual advisory fee for each Fund is 0.50% of its average daily net assets,
reduced on net assets over certain amounts. See "Investment Advisory Services."
    
 
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."
 
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. Both Funds may require redemption of their shares if
the value of the account in the respective Fund is $500 or less. See "Redemption
of Shares."
 
    The above 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' broker-dealers 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 0.30% 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 "The
    Distribution and Service Plans."

</TABLE>
    
 
  The purpose of the foregoing tables is to assist an investor in understanding
the various costs and expenses that an investor in the Funds will bear directly
or indirectly. The "Examples" reflect 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 Funds' 12b-1 plans and service plans, it is
anticipated that 12b-1 and service fees applicable to such Funds will increase
in accordance with such plans to a maximum amount of 0.30% of each Fund's net
assets. Additionally, as California 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 table of the "Annual Fund Operating Expenses." The ten year amount
with respect to the Class B Shares of each 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 "Investment Advisory Services" and
"The Distribution and Service Plans."

THE FUNDS
- --------------------------------------------------------------------------------
 
  The Insured Fund and the California Insured Fund are each separate diversified
sub-trusts of Van Kampen Merritt Tax Free Fund (the "Trust"), an open-end
management investment company, commonly known as a "mutual fund," which is
organized as a Massachusetts 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 Funds. 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 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>   225
 
  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.
 
- --------------------------------------------------------------------------------
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 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
 
                                       18
<PAGE>   226
 
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 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 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
(Moody's) (Aaa, Aa, A and Baa); (2) in the case of short-term notes,
 
                                       19
<PAGE>   227
 
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 Statements 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.
 
  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
 
                                       20
<PAGE>   228
 
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 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 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
 
                                       21
<PAGE>   229
 
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 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 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 transac-
    
 
                                       22
<PAGE>   230
 
   
tions 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 high-grade municipal portfolio 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 of
the Funds' respective assets which may be used to acquire securities on a "when
issued" or "delayed delivery" basis. To the extent the Funds engage in "when
issued" and "delayed delivery" transactions, they will do so for the purpose of
acquiring securities for the Funds' respective portfolios consistent with the
Funds' respective investment objectives and policies and not for the purposes of
investment leverage. No specific limitation exists as to the percentage of the
Funds' assets which may be used to acquire securities on a "when issued" or
"delayed delivery" basis.
    
 
  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 Advisor, 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,
 
                                       23
<PAGE>   231
 
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.
 
- --------------------------------------------------------------------------------
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 Insured Fund's and the California Insured Fund's

PURCHASING SHARES OF THE FUNDS
- --------------------------------------------------------------------------------
 
  The Funds currently offer three classes of shares as discussed below. Shares
of the Funds are continuously offered through Van Kampen American Capital
Distributors, Inc. (the "Distributor"), as principal underwriter, which is
located at One Parkview Plaza, Oakbrook Terrace, Illinois 60181. Shares are also
offered through members of the
 
                                       24
<PAGE>   232
 
National Association of Securities Dealers, Inc. ("NASD") who are acting as
securities dealers ("dealers") and through NASD members or eligible non-NASD
members who are acting as brokers or agents for investors ("brokers"). 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.
 
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 fees with respect to each class of shares that may be
incurred over the anticipated duration of their investment in the Funds.
 
   
  Each Fund currently 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 $1,000.
For purposes of purchasing shares of the Fund, "any person" shall have the
meaning set forth in the section of the Prospectus captioned "Purchasing Shares
of the Fund -- Initial Sales Charge Alternative -- Quantity Discounts." The
minimum subsequent investment with respect to each class of shares is $100. It
is presently the policy of the Distributor not to accept any order for Class B
Shares or Class C Shares in an amount of $1,000,000 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
 
                                       25
<PAGE>   233
 
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). Investors
who intend to hold their shares for a significantly long time may not wish to
continue to bear the ongoing distribution and service expenses of Class C Shares
which, in the aggregate, eventually would exceed the aggregate amount of initial
sales charge and distribution and service expenses applicable to Class A Shares,
irrespective of the fact that a CDSC would eventually not apply to a redemption
of Class C Shares.
 
  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. Only the Class B Shares are
subject to a conversion feature (discussed below). Generally, a class of shares
subject to a higher ongoing distribution fee, service fee or, where applicable,
the conversion feature will have a higher expense ratio and pay lower dividends
than a class of shares subject to a lower ongoing distribution fee, 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 "Net Asset Value."
 
  The administrative expenses that may be allocated to a specific class of
shares will consist of (i) transfer agency 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 that shall be approved by the SEC pursuant to
an amended exemptive order. 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.
 
                                       26

  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
securities 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. See "Net Asset Value."
 
   
  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 or dealer 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
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. 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. In addition, the
Distributor may provide additional compensation to Edward D. Jones & Co.
("Edward D. Jones") or an affiliate thereof based on a combination of its sales
of shares and increases in assets under management. In addition, the Distributor
is sponsoring a sales contest for INVEST Financial Corporation ("INVEST")
relating to the Funds and other funds distributed by the Distributor, pursuant
to which the Distributor may provide an INVEST broker an award valued up to
$750.00 for sales of such funds during the period April 1, 1995, through May 31,
1995. Such payments are made by the Distributor out of its own assets, and not
out of the assets of the Funds. These programs will not change the price an
investor will pay for shares or the amount that the Fund will receive from such
sale.
    
 
INITIAL SALES CHARGE ALTERNATIVE
 
  Investors choosing the initial sales charge alternative purchase Class A
Shares. The public offering price of Class A Shares is equal to the net asset
value per share plus an
 
                                       27
<PAGE>   235
 
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.

* No sales charge is payable at the time of purchase on investments of
  $1,000,000 or more, although for such investments the Funds imposes a
  contingent deferred sales charge 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 million, plus 0.20% on the next $2 million and
  0.08% on the excess over $5 million. See "Purchasing Shares Of The Fund --
  Deferred Sales Charge Alternatives" for additional information with respect to
  contingent deferred sales charges.
    
 
                                       28
<PAGE>   236
 
  QUANTITY DISCOUNTS. Purchasers of Class A Shares may be entitled to reduced
initial sales charges through a combination of investments, rights of
accumulation or a letter of intent (even if investors are not currently making
an investment of a size that would normally qualify for a quantity discount).
Investors, or their dealers or brokers, must notify the proper 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 dealer or broker or the Distributor.
 
  For purposes of determining whether a purchase qualifies for a reduced initial
sales charge, the term "any person" is defined as any one of the following:
 
     (i) an individual, their spouse and children under the age of 21, trust or
         custodial accounts established for any of their sole benefit(s) and any
         corporation, partnership or sole proprietorship which is 100% owned,
         either alone or in combination, by any of the foregoing; or
 
    (ii) a trustee or other fiduciary purchasing for a single trust estate
         (including a pension, profit-sharing or other employee benefit trust
         created pursuant to a plan qualified under Section 401 of the Internal
         Revenue Code, as amended); or
 
   (iii) a "company" as defined in Section 2(a)(8) of the Investment Company
         Act of 1940 (the "Investment Company Act").
 
  1. Combination of Investments. Purchases of shares of the Funds, or of other
Van Kampen Merritt funds distributed by the Distributor subject to an initial
sales charge ("ISC Shares") which are made at any one time by "any person" may
be combined to receive a quantity discount.
 
  2. Rights of Accumulation. Under the rights of accumulation, in determining
the sales charge to be paid for a current purchase of Class A Shares "any
person" (as defined above) may combine their current purchase with the current
public offering price of shares of Class A Shares of a Fund or ISC Shares which
are owned by such person. If the account an investor is combining for rights of
accumulation differs from the account into which the investor's current purchase
is placed, the investor must indicate to the Transfer Agent the account number
(and, if applicable, fund name) of such other account.
 
  3. Letter of Intent. Purchasers of Class A Shares may qualify immediately for
a reduced sales charge by stating their intention to purchase, during a 13 month
period, an amount of Class A Shares that would qualify the investor for a
reduced sales charge. An investor may do this by signing a nonbinding Letter of
Intent, which may be signed at any time within 90 days after the first
investment to be included under the Letter of Intent. Class A Shares purchased
under the "Rights of Accumulation" described above (including investments in ISC
Shares) may be, at the time of the signing of the Letter of Intent, applied
towards completion of an investor's Letter of Intent. In addition, if an
investor's broker or dealer, and the Distributor, agree to refund the
appropriate portion of their respective concessions
 
                                       29
<PAGE>   237
 
to the Funds, the sales charge on an investor's previous purchases made within
90 days may be adjusted to the reduced sales charge under the Letter of Intent,
and the refunded concession will be used to purchase shares of the designated
Fund or Funds at the offering price next determined after receipt of such
monies. Each investment made after signing the Letter of Intent will be entitled
to the sales charge applicable to the total investment indicated in the Letter
of Intent. If an investor does not complete the necessary purchases under the
Letter of Intent within 13 months from the date of the first purchase included
thereunder, the sales charge will be adjusted upward, corresponding to the
amount actually purchased.
 
  When an investor signs a Letter of Intent, Class A Shares of the Funds
purchased with a value of 5% of the amount specified in the Letter of Intent
will be restricted; that is, these shares cannot be sold or redeemed until the
Letter of Intent is satisfied or the additional sales charges have been paid. If
the total purchases made under the Letter of Intent, less redemptions, equal or
exceed the amount specified in the Letter of Intent, these shares will no longer
be restricted. If the total purchases, less redemptions, exceed the amount so
specified, and qualify an investor for a further quantity discount, the
Distributor and the investor's securities dealer or broker will, upon request,
remit their respective portions of the sales concession and with that amount,
purchase additional shares of any of the Funds for the investor's account at the
next computed offering price. If an investor does not complete the necessary
purchases under the Letter of Intent, the sales charges will be adjusted upward
and if, after written notice, the investor does not pay the increased sales
charge, sufficient restricted shares will be redeemed to pay such charge.
 
  OTHER PURCHASE PROGRAMS. Purchasers of Class A Shares may be entitled to
reduced sales charges in connection with unit trust reinvestment programs and
purchases by registered representatives of selling firms or purchases by persons
affiliated with the Funds or the Distributor. Each Fund reserves the right to
modify or terminate these arrangements at any time.
 
  1. Unit Trust Reinvestment Programs. The Funds will permit unitholders of unit
investment trusts to reinvest distributions from such trusts in Class A Shares
of the Funds and ISC Shares with no minimum initial or subsequent investment
requirement, and with a lower sales charge if the administrator of an investor's
unit investment trust program meets certain uniform criteria relating to cost
savings by the Funds and the Distributor. The total sales charge for all
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 dealer, broker 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 securities broker, dealer or 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
Funds during each
 
                                       30
<PAGE>   238
 
distribution period by all investors who choose to invest in the Funds through
the program and (2) provide the Funds' transfer agent with appropriate backup
data for each participating investor in a computerized format fully compatible
with the transfer agent's processing system.
 
   
  As further requirements for obtaining these special benefits, the Funds also
require that all dividends and other distributions by the Funds be reinvested in
additional shares without any systematic withdrawal program. There will be no
minimum for reinvestments from unit investment trusts. The Funds will send
account activity statements to such participants on a quarterly basis only, even
if their investment period is monthly or more frequently. The Funds reserves the
right to modify or terminate this program at any time.
    
 
2. NAV Purchase Options
 
  The classes of investors entitled to purchase shares of the Funds at net asset
value are as follows:
 
 (a) Current or retired Trustees/Directors of funds advised by Van Kampen
     American Capital Investment Advisory Corp., Van Kampen American Capital
     Asset Management, Inc. or John Govett & Co. Limited and such persons'
     families and their beneficial accounts. The term "families" includes a
     person's spouse, children and grandchildren, parents, and a person's
     spouse's parents.
 
   
 (b) Current or retired directors, officers and employees of VK/AC Holding,
     Inc. and any of its subsidiaries, Clayton, Dubilier & Rice, Inc., employees
     of an investment subadviser to any such fund or an affiliate of such
     subadviser; and such persons' families and their beneficial accounts.
    
 
 (c) Directors, officers, employees and registered representatives of financial
     institutions that have a selling agreement with the Distributor and their
     spouses and minor children 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.
 
   
 (d) 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 either Fund alone, or in any combination
     of Class A Shares of the Funds and ISC Shares of other funds distributed by
     the Distributor as described herein under "Purchasing Shares Of The Funds
     -- Initial Sales Charge Alternative -- Quantity Discounts," during the 13
     month period commencing with the first investment pursuant hereto equals at
     least $1 million. The Distributor may pay such entities through which
     purchases are made an amount up to 0.50% of the amount invested, over a
     twelve month period following such transaction.
    
 
                                       31
<PAGE>   239
 
 (e) Trustees and other fiduciaries purchasing shares for retirement plans of
     organizations with retirement plan assets of $10 million or more. The
     Distributor may pay commissions of up to 1% for such purchases.
 
 (f) Accounts as to which a selling firm charges an account management fee
     ("wrap accounts"), provided the selling firm has executed a supplemental
     agreement to their existing selling agreement with the Distributor.
 
 (g) Investors purchasing shares of the Funds 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.
 
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 Funds, at a percentage rate of the dollar value of the CDSC Shares
purchased from the Funds by such brokers, dealers and financial intermediaries,
which percentage rate will be equal to (i) 1.00% with respect to Class A Shares
in an amount of $1 million or more; (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 Funds will receive from such sale. Sales compensation with
respect to Class A Shares subject to a CDSC is set forth under "Purchasing
Shares Of The Fund -- Initial Sales Charge Alternative".
 
  CDSC Shares redeemed within a specified period of time generally will be
subject to a contingent deferred sales charge at the rates set forth below. The
amount of the contingent deferred sales charge 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 contingent
deferred sales charge 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 contingent deferred sales charge 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
Funds 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 contingent deferred sales charge and the
distribution and services fees facilitates the ability of the Funds to sell such
CDSC Shares without a sales charge being deducted at the time of purchase.
 
  In determining whether a contingent deferred sales charge 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 contingent deferred sales charge 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, if any, and fourth of CDSC Shares held
longest during the period of time that a contingent deferred sales charge 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).
 
  The contingent deferred sales charge is waived (i) on a redemption of shares
following the death of a shareholder, or (ii) to the extent that the redemption
represents a minimum required distribution from an IRA or other retirement plan
to a shareholder who has attained the age of 70 1/2.
 
   
  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 $1,000,000 or more,
although for such investments the Funds impose a contingent deferred sales
charge 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 million, plus 0.20% on the next $2 million and 0.08% on the
excess over $5 million.

  CLASS B SHARES. Class B Shares redeemed within the number of years of purchase
set forth below generally will be subject to a contingent deferred sales charge
at the rates set forth below, charged as a percentage of the dollar amount
subject thereto:

  The contingent deferred sales charge generally is waived on redemptions of
Class B Shares made pursuant to the Systematic Withdrawal Program. See
"Shareholder Programs -- Systematic Withdrawal Program."
 
  CLASS C SHARES. Class C Shares of each Fund redeemed within the first twelve
months of purchase generally will be subject to a contingent deferred sales
charge 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 the Insured Fund automatically will
convert to Class A Shares of the Insured Fund seven years after the end of the
month in which a shareholder's order to purchase such Class B Shares was
accepted and thereafter will be subject to the lower aggregate distribution and
service fees applicable to Class A Shares of the Insured Fund. Class B Shares of
the California Insured Fund automatically will convert to Class A Shares of the
California Insured Fund six years after the end of the
 
                                       34
<PAGE>   242
 
month in which a shareholder's order to purchase such Class B Shares was
accepted and thereafter will be subject to the lower aggregate distribution and
service fees applicable to Class A Shares of the California Insured Fund. The
purpose of the conversion feature is to relieve the holders of Class B Shares
that have been outstanding for a period of time sufficient for the Distributor
to have been compensated for distribution expenses related to the Class B Shares
from most of the burden of such distribution-related expenses.
 
  For purposes of conversion to Class A Shares, Class B Shares purchased through
the reinvestment of dividends and distributions paid in respect of Class B
Shares in a shareholder's account will be considered to be held in a separate
sub-account. Each time any Class B Shares in the shareholder's account (other
than those in the sub-account) convert to Class A Shares, an equal pro rata
portion of the Class B Shares in the sub-account also will convert to Class A
Shares. The holding period applicable to a Class B Share acquired through the
use of the exchange privilege (discussed below) shall be the holding period
applicable to a Class B Share of such Fund acquired other than through use of
the exchange privilege. For purposes of calculating the holding period
applicable to a Class B Share of the Fund prior to conversion, a Class B Share
of the Fund issued in connection with an exercise of the exchange privilege, or
a series of exchanges, shall be deemed to have been issued on the date on which
the investor's order to purchase the exchanged Class B Share was accepted or, in
the case of a series of exchanges, when the investor's order to purchase the
original Class B Share was accepted.
 
  The conversion of Class B 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 services fee and transfer agency costs
with respect to Class B 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 Class B
Shares does not constitute a taxable event under federal income tax law. The
conversion of Class B Shares to Class A Shares may be suspended if such an
opinion is no longer available. In that event, no further conversions of Class B
Shares would occur, and Class B Shares might continue to be subject to the
higher aggregate distribution and service fees for an indefinite period.
 
- --------------------------------------------------------------------------------
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 the 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
 
                                       35
<PAGE>   243
 
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 the Funds' transfer agent receives payments for such shares.
However, shares become entitled to dividends on the day the Funds' transfer
agent 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 information under the "Distributions" section of the
Account Application bound in this Prospectus or available from Van Kampen
Merritt Funds, State Street Bank and Trust Company, c/o National Financial Data
Services, P.O. Box 419001, Kansas City, MO 64141-6001 (the "Transfer Agent").
After the Transfer Agent 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 monthly distributions and any annual 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 elects otherwise to the Transfer Agent. This election may be made by
telephone by calling 1-800-341-2911 or in writing to the Transfer Agent. For
inquiries through Telecommunications Device for the Deaf (TDD), dial
1-800-772-8889, during the hours of 7:30 a.m. to 4:00 p.m. Central Standard
Time. If a shareholder elects to change the method of distribution, such change
will be effective only with regard to distributions for which the record date is
seven or more business days after the Transfer Agent has received the request.
 
- --------------------------------------------------------------------------------
REDEMPTION OF SHARES
- --------------------------------------------------------------------------------
 
  WRITTEN REDEMPTION REQUEST.  Shareholders may sell shares without charge
(other than, with respect to the CDSC Shares, any applicable contingent deferred
sales charge) at any time by mailing a written redemption request in proper form
to the Transfer Agent. This request should be sent to Van Kampen Merritt Funds,
c/o National Financial Data Services, P.O. Box 419001, Kansas City, MO
64141-6001. The request should indicate the number of shares to be redeemed by a
particular Fund, identify the account number and be signed exactly as the shares
are registered. If the amount being redeemed is in excess of $50,000 or if the
redemption proceeds will be sent to an address other than the address of record,
the signature(s) must be guaranteed by a member firm of a principal stock
exchange, a commercial bank or trust company which is a member of the Federal
Deposit Insurance Corporation, a credit union or a savings association. The
guarantee
 
                                       36
<PAGE>   244
 
must state the words "Signature Guaranteed" along with the name of the granting
institution. Shareholders should verify with the institution that it is an
eligible guarantor prior to signing. A guarantee from a notary public is not
acceptable. If certificates are held for the shares being redeemed, such
certificates must be sent and endorsed for transfer or accompanied by an
endorsed stock power. Share certificates should be sent by registered mail to
National Financial Data Services, 1004 Baltimore Avenue, Dwight Building, 6th
Floor, Kansas City, MO 64105. Shareholders will receive the net asset value per
share next computed after the Transfer Agent receives the redemption request and
certificates (if any) in proper form. Any applicable contingent deferred sales
charge with respect to CDSC Shares redeemed will be deducted from the redemption
proceeds prior to transmittal of such proceeds to the shareholder.
 
   
  TELEPHONE REDEMPTIONS.  Shareholders may sell shares by calling the Funds at
1-800-341-2911 before 3:00 p.m. Central Standard Time to request a redemption
for a particular Fund. For inquiries through Telecommunications Device for the
Deaf (TDD), dial 1-800-772-8889, during the hours of 7:30 a.m. to 3:00 p.m.
Central Standard Time. There is a $500 minimum and a $1,000,000 maximum per
request if the redemption proceeds are to be mailed to the shareholder. If the
redemption proceeds are to be wired to a bank there is a minimum of $5,000 and a
$1,000,000 maximum per request. Prior to redeeming shares by telephone the
"Expedited Telephone Redemption" section of either the Account Application or
Expedited Telephone Redemption and Exchange Request Form (the "Authorization")
must be completed and on file with the Transfer Agent. The signature(s) on the
Authorization must be guaranteed by a member firm of a principal stock exchange,
a commercial bank or trust company which is a member of the Federal Deposit
Insurance Corporation, a credit union or a savings association unless the
Authorization is completed at the time an account is originally established. The
guarantee must state the words "Signature Guaranteed" along with the name of the
granting institution. Shareholders should verify with the institution that it is
an eligible guarantor prior to signing. A guarantee from a notary public is not
acceptable. A redemption requested by telephone will be processed at the net
asset value next determined after receipt of the request. Any applicable
contingent deferred sales charge with respect to CDSC Shares redeemed will be
deducted from the redemption proceeds prior to transmittal of such proceeds to
the shareholder. The proceeds would then be made payable to the registered
shareowner(s) and mailed to the address registered on the account or wired to a
bank, as requested on the Authorizations. Shareholders cannot redeem shares by
telephone if stock certificates are held for those shares. This service is not
available with respect to shares held in an Individual Retirement Account (IRA)
for which State Street Bank and Trust Company acts as custodian. In addition,
this service is not available with respect to shares purchased by check until 15
days after purchase.
    
 
   
  By establishing the telephone redemption service, a shareholder authorizes a
Fund or its agent to act upon the instructions of any person by telephone to
redeem shares for any account for which such service has been authorized. The
Fund, the Distributor, the Transfer Agent and National Financial Data Services,
Inc. ("NFDS") employ procedures reasonably believed to confirm that instructions
communicated by telephone are genuine. Such procedures include requiring a
person attempting to redeem shares by telephone to
    
 
                                       37
<PAGE>   245
 
   
provide, on a recorded line, the name on the account, a social security number
or tax identification number and such additional information as may be included
in the Authorization. A shareholder also agrees that none of the Funds, the
Distributor, the Transfer Agent or National Financial Data Services ("NFDS")
will be liable for any loss, liability, cost or expense arising out of any
request, including any fraudulent or unauthorized request. This service may be
amended or terminated at any time by the Transfer Agent or the Funds. If a
shareholder is unable to reach a Fund by telephone, he or she may redeem shares
pursuant to the procedures set forth above under the caption "Written Redemption
Requests." During periods of extreme economic or market changes, it may be
difficult for investors to reach the Funds by telephone and to effect telephone
redemptions.
    
 
  REDEMPTION THROUGH DEALERS.  Shareholders may sell shares (whether in
certificate or book-entry form) through their securities dealer, who will
telephone the request to the Distributor. Shareholders will receive the net
asset value next determined after such shareholder places the sell order. Any
applicable contingent deferred sales charge with respect to CDSC Shares redeemed
will be deducted from the redemption proceeds prior to transmittal of such
proceeds to the shareholder. It is the responsibility of the shareholder's
broker, dealer or financial intermediary to transmit the redemption order to the
Distributor. Because the Funds generally determine net asset value once each
business day as of the close of business, sell orders placed through a
shareholder'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 shareholder's order to be fulfilled on the basis of the
net asset value to be determined that day. Any change in the redemption price
due to the failure of the Distributor to receive a sell order prior to such time
must be settled between the investor and the broker, dealer, or financial
intermediary submitting the order. The Funds do not charge for this transaction
(other than any applicable contingent deferred sales charge). Shareholders must
submit a written redemption request in proper form to their securities dealer
within five business days after calling the dealer with the sell order. The
request should indicate the number of shares to be redeemed, identify the
account number and the order or confirmation number assigned to the trade, and
be signed by the shareholder exactly as the shares are registered. If the amount
of the redemption exceeds $50,000 or if the redemption proceeds will be sent to
an address other than the address of record, signature(s) must be guaranteed by
a member firm of a principal stock exchange, a commercial bank or trust company
which is a member of the Federal Deposit Insurance Corporation, a credit union
or a savings association. The guarantee must state the words "Signature
Guaranteed" along with the name of the granting institution. Shareholders should
verify with the institution that it is an eligible guarantor prior to signing. A
guarantee from a notary public is not acceptable. If certificates are held for
the shares being redeemed, such certificates must be sent endorsed for transfer
or accompanied by an endorsed stock power. Certificates should be sent by
registered mail to Van Kampen Merritt Funds, c/o National Financial Data
Services, 1004 Baltimore Avenue, Dwight Building, 6th Floor, Kansas City, MO
64105-1807.
 
                                       38
<PAGE>   246
 
   
  REDEMPTION UPON DISABILITY.  The Fund will waive the CDSC on Class B Share
redemptions following the disability of a Class B shareholder. An individual
will be considered disabled for this purpose if he or she meets the definition
thereof in Section 72(m)(7) of the Internal Revenue Code (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 Fund will
require satisfactory proof of disability before it determines to waive the CDSC
on Class B Shares.
    
 
   
  In cases of disability, the CDSC on Class B 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 applies to a total or partial redemption, but only to redemptions of
shares held at the time of the initial determination of disability.
    
 
  GENERAL.  Whether shares are redeemed by a Fund or sold through a securities
dealer, a check for the proceeds (net of any required tax withholding and, with
respect to CDSC Shares, any applicable contingent deferred sales charge)
ordinarily will be mailed to shareholders or their dealer as the case may be
within seven calendar days after a redemption request or repurchase order and
share certificates (if any) are received in proper form as set forth above. Wire
transfers from a Fund of redemption proceeds, in the manner described above,
ordinarily will be transmitted to the shareholder within one business day. If
any shares are redeemed or repurchased shortly after purchase, the respective
Fund will not mail the proceeds until checks received for the purchase of shares
have cleared, which may take 10 days or more. The proceeds, of course, may be
more or less than the cost of the shares.
 
  The right of redemption or resale to the Funds may be suspended or the date of
payment postponed during any period when the New York Stock Exchange is closed
(other than customary weekend and holiday closings), when an emergency exists as
defined by rules and regulations of the SEC, or during any period when the SEC
has by order permitted such suspension or postponement.
 
  The Funds reserve the right to redeem any investment if the value of an
account falls below $500. Before any Fund makes such redemption it will provide
the shareholder with written notice and 30 days in which to make an additional
investment sufficient to increase the value of the account to at least $500.
 
- --------------------------------------------------------------------------------
NET ASSET VALUE
- --------------------------------------------------------------------------------
 
  The net asset value per share of each of the Funds is determined by
calculating the total value of a Fund's assets, deducting its total liabilities,
and dividing the result by the
 
                                       39
<PAGE>   247
 
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 a Fund's
portfolio securities such that the Fund's net asset value per share might be
materially affected. The Funds reserve 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 each
Fund is a separate sub-trust. 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.
 
- --------------------------------------------------------------------------------
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 the Funds' 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., Business Week, Forbes or other industry publications.
 
   
  The Funds' yield quotations are determined for each class of the Funds' 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 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 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) 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.
    
 
                                       40
<PAGE>   248
 
  Tax-equivalent yield demonstrates the taxable yield required to produce an
after-tax yield equivalent to that of the Fund's yield. A Fund's tax-equivalent
yield quotation for a 30 day period as described above is computed for each
class of the Funds' 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 Funds calculate average compounded total return for each class of the
Funds' 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 respective 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.
 
  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 a given 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 the Funds' shares.
 
  From time to time, the Funds may compare its performance to certain securities
and unmanaged indices which may have different risk/reward characteristics than
the Funds. Such characteristics may include, but are not limited to, tax
features, guarantees,
 
                                       41
<PAGE>   249
 
insurance and the fluctuation of principal and/or return. In addition, from time
to time, the Funds may utilize sales literature that includes hypotheticals.
 
  Please consult the Statements of Additional Information for more information
regarding the Funds' performance.

TAX STATUS
- --------------------------------------------------------------------------------
 
  FEDERAL TAXES.  The Funds each have qualified and intend to continue to
qualify as regulated investment companies under Subchapter M of the Internal
Revenue Code of 1986, as amended (the "Code"). To qualify as a regulated
investment company, each 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 each Fund so qualifies and if it distributes to its shareholders
at least 90% of its net investment income (including tax-exempt interest and
other taxable income including net short-term capital gains, but not net capital
gains, which is 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. Each Fund intends to distribute at least the
minimum amount of net investment income to satisfy the 90% distribution
requirement. Each Fund will not be subject to federal income tax on any net
capital gain distributed to its shareholders. As sub-trusts of a Massachusetts
business trust, the Funds will not be subject to any excise or income taxes in
Massachusetts as long as each qualifies as a regulated investment company for
federal income tax purposes. In order to avoid a 4% excise tax each Fund will be
required to distribute by December 31 of each year at least 98% of its ordinary
income for such year and at least 98% of its capital gain net income (the latter
of which is generally computed on the basis of the one-year period ending on
October 31 of such year), plus any required distribution 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 taxed in the hands
of, a Fund will be treated as having been distributed.
 
  If a Fund qualifies as a regulated investment company and satisfies the 90%
distribution requirement, and if, at the close of each quarter of such Fund's
taxable year, at least 50% of the total of such Fund's assets consists of
obligations exempt from federal income tax ("tax-exempt obligations"), such Fund
will be qualified to pay exempt-interest dividends to its shareholders to the
extent of its tax-exempt interest income (less expenses applicable thereto).
Exempt-interest dividends are excludable from a shareholder's gross income for
federal income tax purposes, but may be taxable distributions for state, local
and other tax purposes. Exempt-interest dividends are included, however, 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. Interest expense with respect to indebtedness incurred or continued by a
shareholder to purchase or carry shares of a Fund is not deductible to the
extent that such interest relates to exempt-interest dividends received from
such Fund.
 
  The Internal Revenue Service has publicly ruled that payments of insurance
proceeds representing interest on defaulted tax-exempt obligations are
excludable from gross
 
                                       42
<PAGE>   250
 
income to the same extent that such payments would have been excludable if they
had been directly made by the issuer of the insured obligations. Accordingly,
insurance proceeds received by the Insured Fund and the California Insured Fund
under a policy obtained for such securities prior to their purchase by such
Funds or from AMBAC and any other insurer with whom the Insured Fund and the
California Insured Fund maintains a policy described in this Prospectus will be
tax-exempt interest income of the Insured Fund and the California Insured Fund
to the same extent as if such payments were made by the issuer of the insured
obligations, and will be includable by the Insured Fund and the California
Insured Fund in calculating their exempt-interest dividends. With respect to
municipal leases with "non-appropriation" clauses, however, there can be no
assurance that payments made by the insurers on such lease obligations will be
tax-exempt interest income of the Insured Fund or the California Insured Fund to
the same extent as if such payments were made by the issuer of the obligations
and, therefore, includable by the Funds in calculating their exempt-interest
dividends.
 
  Distributions of a Fund's investment company taxable income (which does not
include tax-exempt interest income) are taxable to shareholders as ordinary
income whether received in shares or in cash. Shareholders who receive
distributions in the form of additional shares will have a basis for federal
income tax purposes in each such share equal to the value thereof on the
reinvestment date. Distributions of a Fund's net capital gain ("capital gains
dividends"), if any, are taxable to shareholders at the rates applicable to
long-term capital gains regardless of the length of time shares of such Fund
have been held by such shareholders. Distributions in excess of the Funds'
earnings and profits, such as distributions of principal, will first reduce the
adjusted tax basis of the shares held by the shareholders and, after such
adjusted tax basis is reduced to zero, will constitute capital gains to such
shareholders (assuming such shares are held as a capital asset). Each Fund will
inform shareholders of the source and tax status of such distributions promptly
after the close of each calendar year. Distributions from the Funds will not be
eligible for the dividends received deduction for corporations.
 
  Exempt-interest dividends allocable to interest received by a Fund on certain
"private activity" obligations issued after August 7, 1986 will be treated as
interest on such obligations and thus will give rise to an item of tax
preference that will increase a shareholder's alternative minimum taxable
income. Unless otherwise provided in regulations, the portion of the Fund's
interest on such "private activity" obligations allocable to shareholders will
correspond to the portion of the Fund's total net tax-exempt income distributed
to shareholders. In addition, for corporations, alternative minimum taxable
income will be increased by a percentage of the amount by which a measure of
income that includes interest on tax-exempt obligations exceeds the amount
otherwise determined to be the alternative minimum taxable income. Accordingly,
investment in a Fund may cause shareholders to be subject to (or result in an
increased liability under) the alternative minimum tax.
 
  Exempt-interest dividends will not be tax-exempt to the extent made to any
shareholder who is a "substantial user" of the facilities financed by tax-exempt
obligations held by the Fund or "related persons" of such substantial users.
 
                                       43
<PAGE>   251
 
  Redemption or resale of shares of a Fund will be a taxable transaction for
federal income tax purposes. Redeeming shareholders will recognize gain or loss
in an amount equal to the difference between their basis in such redeemed shares
of such Fund 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 generally be
long-term if such shareholders have held shares for more than one year. Any loss
realized on shares held for six months or less will be disallowed to the extent
of any exempt-interest dividends received with respect to such shares. If such
loss is not entirely disallowed, it will be treated as a long-term capital loss
to the extent of any capital gains dividends received with respect to such
shares.
 
  Some of the Funds' investment practices are subject to special provisions of
the Code that, among other things, may defer the use of certain losses of a Fund
and affect the holding period of the securities held by a Fund and the character
of gains or losses realized by a Fund. These provisions may also require a Fund
to mark-to-market some of the positions in its portfolio (i.e., treat them as if
they were closed out), 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 requirement for avoiding
income taxes. Each Fund will monitor its transactions and may make certain tax
elections in order to mitigate the effect of these rules and prevent
disqualification of such Fund as a regulated investment company.
 
  Investments of each 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, each
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 federal income taxes. In order to
generate sufficient cash to make distributions necessary to satisfy the 90%
distribution requirement and avoid federal income taxes, a Fund may have to
dispose of securities that it would otherwise have continued to hold. Discount
relating to certain stripped tax-exempt obligations may constitute taxable
income when distributed to shareholders.
 
  A 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 a Fund's gross income be derived from the disposition of securities held
for less than three months.
 
  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 a month and paid in January of the following
year will be treated as having been distributed by the Fund and received by the
shareholders on the December 31 of the year in which the dividend was declared.
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 is actually made.
 
                                       44
<PAGE>   252
 
  Each Fund is required, in certain circumstances, to withhold 31% of taxable
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.
 
  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
for general information only. Prospective investors should consult their tax
advisors regarding the specific federal and California tax consequences of
holding and disposing of shares as well as the effects of other state, local and
foreign tax laws.

- --------------------------------------------------------------------------------
THE DISTRIBUTION AND SERVICE PLANS
- --------------------------------------------------------------------------------
 
  Each Fund has adopted a distribution plan (the "Distribution Plan") with
respect to each class of its shares pursuant to Rule 12b-1 under the Investment
Company Act. Each Fund 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,
distributor of each class of the Funds' shares, sub-agreements between the
Distributor and members of the NASD who are acting as securities dealers, NASD
members or eligible non-members who are acting as brokers or agents and similar
agreements between the Funds and financial intermediaries who are acting as
brokers (collectively, "Selling Agreements") that may provide for their
customers or clients certain services or assistance. Brokers, dealers and
financial intermediaries that have entered into Selling Agreements with the
Distributor and sell shares of the Funds are referred to herein as "financial
intermediaries."
 
  Class A Shares.  Each Fund may spend an aggregate amount up to 0.30% 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 financial intermediaries and in connection with the
maintenance of such shareholders' accounts. Each Fund pays the Distributor the
lesser of the balance of the 0.30% not paid to such financial intermediaries or
the amount of the Distributor's actual distribution related expense.
 
  Class B Shares.  Each Fund 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 Fund 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
financial intermediaries and in connection with the maintenance of such
shareholders' accounts.
 
  Class C Shares.  Each Fund 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 Fund, or the Distributor as agent
for the respective Fund, pays financial intermediaries in connection with the
distribution of the
 
                                       47
<PAGE>   255
 
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 financial intermediary's customers. Each Fund pays the Distributor the
lesser of the balance of 0.75% not paid to such financial intermediaries or the
amount of the Distributor's actual distribution related expense. In addition,
each Fund 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 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 contingent deferred sales charge. 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. Each Fund will disclose in its
prospectus from time to time the then current amount of any such unreimbursed
expenses with respect to each class of CDSC Shares expressed as a dollar amount
and as a percent of the Funds' total net assets. As of December 31, 1994, there
were $38,971 and $2,788 of unreimbursed distribution expenses with respect to
Class B Shares and Class C Shares, respectively of the Insured Fund,
representing 0.00% and 0.00% of the Insured Fund's total net assets. As of
December 31, 1994, there were $20,141 and $4,129 of unreimbursed distribution
expenses with respect to Class B Shares and Class C Shares, respectively of the
California Insured Fund, representing 0.01% and 0.00% of the California Insured
Fund's total net assets. 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
contingent deferred sales charges.
    
 
  Because each Fund is a sub-trust of the Trust, amounts paid to the Distributor
as reimbursement for expenses of one sub-trust of the Trust may indirectly
benefit the other funds which are sub-trusts of the Trust. The Distributor will
endeavor to allocate such
 
                                       48
<PAGE>   256
 
expenses among such funds in an equitable manner. The Distributor will not use
the proceeds from the contingent deferred sales charge applicable to a
particular class of CDSC Shares to defray distribution related expenses
attributable to any other class of CDSC 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.
 
- --------------------------------------------------------------------------------
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,
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.
 
- --------------------------------------------------------------------------------
SHAREHOLDER PROGRAMS
- --------------------------------------------------------------------------------
 
   
  SHARE CERTIFICATES.  As a rule, 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 the respective 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 State Street Bank and Trust
Company, c/o National Financial Data Services, P.O. Box 419001, Kansas City, MO
64141-6001, Attn: Van Kampen Merritt Funds, requesting an "affidavit of loss"
and to obtain a Surety Bond in a form acceptable to the Transfer Agent. On the
date the letter is received the Transfer Agent will calculate no more than 2.00%
of the net asset value of the issued shares, and bill the party to whom the
certificate was mailed.
    
 
   
  SYSTEMATIC WITHDRAWAL PROGRAM.  If a shareholder's Class A Share account or
Class B Share account is valued at $10,000 or more, and such shareholder's
dividends are being reinvested, a requested dollar amount may be paid from such
account to any person monthly, quarterly, semiannually or annually. The minimum
amount that may be withdrawn each period is $50; withdrawals will be made on the
seventh business day of the month in which they are scheduled to occur.
Depending upon the size of the payments requested and the fluctuations in the
net asset value of the shares redeemed, redemptions for the purpose of making
such payments may reduce or even exhaust the amounts in such account. If an
investor acquires additional shares of a Fund after joining the Systematic
Withdrawal Program, the investor must inform the respective Fund if he or she
wants the new shares to be subject to the Systematic Withdrawal Program by
telephoning the respective Fund at 1-800-341-2911.
    
 
                                       49
<PAGE>   257
 
   
  With respect to redemptions of Class B Shares made pursuant to the Systematic
Withdrawal Program, an investor may annually redeem up to 12% of the net asset
value of the investor's initial investment in Class B Shares of a Fund or, if
the investor does not join the program on the date of his or her initial
investment, the net asset value of the investor's Class B Shares on the date the
investor elects to participate in the Systematic Withdrawal Program. Each Fund
will waive the contingent deferred sales charge applicable to Class B Shares
redeemed pursuant to the respective Fund's Systematic Withdrawal Program.
    
 
  It will ordinarily be disadvantageous to purchase shares (except through
reinvestment of distributions) while participating in a systematic withdrawal
program because a shareholder will be paying a sales charge to purchase shares
at the same time that shares are being redeemed upon which a sales charge may
already have been paid. Therefore, neither Fund will knowingly permit a
shareholder to make additional investments of less than $5,000 if at the same
time such shareholder is making systematic withdrawals at a rate greater than
the distribution being paid on such shareholder's shares. The Funds reserve the
right to amend or terminate the systematic withdrawal program on thirty days
notice, and a shareholder may withdraw from the program at any time.
 
  EXCHANGE PRIVILEGE.  Any Class A Shares of a Fund which have been registered
in a shareholder's name for at least 15 days may be exchanged for shares of any
other Van Kampen Merritt mutual fund distributed by the Distributor that offers
an exchange privilege. Under the exchange privilege, each Fund offers to
exchange its Class A Shares for Class A Shares of other such funds on the basis
of relative net asset value per share. Any ISC Shares exchanged into either Fund
that have been charged a sales load lower than the sales load applicable to
Class A Shares of the respective Fund will be charged the applicable sales load
differential upon exchange. ISC Shares of the Van Kampen Merritt Money Market
Fund and Van Kampen Merritt Tax Free Money Fund which have not previously been
charged a sales load (except for shares purchased via the reinvestment option)
will be charged the applicable sales load upon exchange into either Fund.
 
  Class B Shareholders of the Funds may exchange their Class B Shares
("Outstanding Class B Shares") for Class B Shares of other Van Kampen Merritt
mutual funds sponsored by the Distributor ("New Class B Shares") on the basis of
relative net asset value per Class B Share, without the payment of any
contingent deferred sales charge that might otherwise be due on redemption of
the Outstanding Class B Shares. Class B Shares of a fund acquired through use of
the exchange privilege will be 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.
 
   
  Class C Shares of the Funds are exchangeable for Class C Shares of other Van
Kampen Merritt mutual funds distributed by the Distributor on the same terms set
forth in the preceding paragraph with respect to Class B Shares, except that
Class C Shares do not convert to Class A Shares. The exchange privilege with
respect to any Van Kampen Merritt money market fund sponsored by the Distributor
is not available for Class C Shareholders.

<PAGE>   258
 
   
  In order to qualify for the exchange privilege, it is required the shares
being exchanged have a net asset value of at least $1,000 (unless prior approval
has been obtained from the respective Fund). Shareholders also may effect an
exchange by telephone by calling the Fund at 1-800-341-2911 prior to 3:00 p.m.
Central Standard Time and requesting the exchange. For inquiries through
Telecommunications Device for the Deaf (TDD), dial 1-800-772-8889, during the
hours of 7:30 a.m. to 3:00 p.m. Central Standard Time. The exchange will be
processed at the net asset value next determined after receipt of such request.
By utilizing the telephone exchange service, a shareholder authorizes the
respective Fund or its agent to act upon the instructions of any person by
telephone to exchange shares from any account for which such service has been
authorized to any identically registered account(s) with any Van Kampen Merritt
fund distributed by the Distributor that offers an exchange privilege. A
shareholder also agrees that none of the Funds, the Distributor, the Transfer
Agent nor NFDS will be liable for any loss, liability, cost or expense arising
out of any request, including any fraudulent request. The staff of the SEC
currently is reviewing its position with respect to such agreements. This
service may be amended or terminated at any time by the Transfer Agent or the
Funds. If a shareholder has certificates for any shares being exchanged, such
certificates must be surrendered prior to the exchange in the same manner as in
redemption of such shares (see "Redemption of Shares--Telephone Redemptions").
Any shares exchanged between one of the Funds and any of the other funds will
begin earning dividends on the next business day after the exchange is effected.
Before effecting an exchange, shareholders in either of the Funds 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.
    
 
  An exchange between Van Kampen Merritt funds pursuant to the exchange
privilege is treated as a sale for federal income tax purposes, and depending
upon the circumstances, a short- or long-term capital gain or loss may be
realized.
 
  The exchange privilege may be modified or terminated at any time, subject to
the requirement that the Funds give prominent notice thereof at least 60 days
prior to the modification or termination in certain circumstances. Each Fund
reserves the right to limit the number of times a shareholder may exercise the
exchange privilege.
 
  AUTOMATED MULTIPLE ACCOUNT SHAREHOLDER SERVICES (AMASS(SM)).
 
   
  1. 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
the Transfer Agent 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
    
 
                                       51
<PAGE>   259
 
proceeds of such redemption. Once enrolled in the ACH plan, a shareholder may
terminate participation at any time by writing the Transfer Agent.
 
  2. Automated Dividend Programs.  The Funds will, upon the election of a
shareholder, automatically deposit distributions from a shareholder's account
directly into a shareholder's bank account.
 
   
  3. Dividend Diversification.  In addition to the foregoing, monthly
distributions and any net long-term capital gain distributions to a
shareholder's account may be invested in the same class of shares of any other
Van Kampen Merritt mutual fund distributed by the Distributor at the then
current net asset value, WITHOUT A SALES CHARGE, upon election by a shareholder.
This election may be made on the account application bound in this Prospectus,
by written notice to the Transfer Agent or by calling a Fund directly at 1-800-
341-2911, during the hours of 7:00 a.m. to 7:00 p.m. Central Standard Time. For
inquiries through Telecommunications Device for the Deaf (TDD), dial
1-800-772-8889. In order to qualify for this privilege, a shareholder must have
established an account in the other fund prior to electing this privilege. This
privilege may be modified or terminated by the Funds at any time.
    
 
  4. Easy Account Savings Enhancement Plan (EASESM).  Once a shareholder has
opened an account with the minimum $1,000 investment, the automatic investment
option may be utilized to make regular electronic monthly investments of $100 or
more into such shareholder's account with the respective Fund. In order to
utilize this option, a shareholder must fill out and sign the appropriate
section of the application attached to this Prospectus or the EASESM application
which is available from the Transfer Agent, the Funds, such shareholder's broker
or dealer, or the Distributor. Once the Transfer Agent has received this
application, such shareholder's checking account at his or her designated local
bank will be debited each month in the amount authorized by such shareholder to
purchase shares of the respective Fund. Once enrolled in the EASESM program, a
shareholder may change the monthly amount or terminate participation at any time
by writing or calling the Transfer Agent. Shareholders in the EASESM program
will receive a confirmation of these transactions from the respective Fund at
least quarterly, and their regular bank account statements will show the debit
transaction each month.
 
  By electing to utilize any of the foregoing services, a shareholder authorizes
the Transfer Agent or its agent to act upon the instructions indicated in the
appropriate section of the application in performing such services by either
withdrawing funds for deposit in the Funds pursuant to the EASESM Plan, or
depositing distributions and redemptions in the bank account indicated by the
voided check or deposit slip accompanying the shareholder's election or by
depositing the shareholder's distributions in the Van Kampen Merritt fund
account indicated. A shareholder also agrees that none of the Funds, the
Distributor, the Transfer Agent nor NFDS will be liable for any loss, liability,
cost or expense arising out of any request, including any fraudulent request.
This service may be amended or terminated at any time by the Transfer Agent or
by the Funds.
 
  REINSTATEMENT PRIVILEGE.  A shareholder who has redeemed Class A Shares or
Class B Shares of either Fund may, within 120 days, repurchase Class A Shares of
the respective
 
                                       52
<PAGE>   260
 
Fund, or shares of other Van Kampen Merritt mutual funds distributed by the
Distributor, in an amount of at least $500 and not exceeding the redemption
proceeds received, at a purchase price equal to the net asset value next
determined after the reinstatement request is received by the Transfer Agent or
the Distributor. A Class C Shareholder who has redeemed shares of either Fund
may repurchase Class C Shares of the respective Fund, or shares of other Van
Kampen Merritt mutual funds distributed by the Distributor with credit given for
any contingent deferred sales charge paid upon such redemption.
 
  Exercising the reinstatement privilege will not affect the character of any
gain or loss realized on the redemption for federal income tax purposes, except
that if the redemption resulted in a loss, the reinstatement may result in the
loss being disallowed under the "wash sale" rules.

investment or withdrawal is made in or from their account. Information for
federal income tax purposes will be provided at the end of the year. Such
statements will present separately information with respect to each class of a
Fund's shares. It is expected that the transfer agency costs attributable to the

                             THE FUND AND THE TRUST
 
  The Fund is a separate diversified sub-trust of Van Kampen Merritt Tax Free
Fund (the "Trust"), an open-end diversified management investment company. The
Trust is an unincorporated business trust established under the laws of the
Commonwealth of Massachusetts by a Declaration of Trust dated August 15, 1985.
The Declaration of Trust permits the Trustees to issue an unlimited number of
full and fractional shares in separate sub-trusts. At present, the Fund, Van
Kampen Merritt Tax Free High Income Fund, Van Kampen Merritt California Insured
Tax Free Fund, Van Kampen Merritt Municipal Income Fund, Van Kampen Merritt
Limited Term Municipal Income Fund, Van Kampen Merritt Florida Insured Tax Free
Income Fund, Van Kampen Merritt New Jersey Tax Free Income Fund and Van Kampen
Merritt New York Tax Free Income Fund have been organized as sub-trusts of the
Trust and have commenced investment operations. Van Kampen Merritt California
Tax Free Income Fund, Van Kampen Merritt Michigan Tax Free Income Fund, Van
Kampen Merritt Missouri Tax Free Income Fund and Van Kampen Merritt Ohio Tax
Free Income Fund have been organized as sub-trusts of the Trust but have not
commenced investment operations. Other sub-trusts 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. and was reorganized into
a sub-trust of the Trust as of February 22, 1988.
 
  Each share of the Trust represents an equal proportionate interest in the
assets of its respective sub-trust with each other share in such sub-trust and
no interest in any other sub-trust. No sub-trust is subject to the liabilities
of any other sub-trust. The Declaration of Trust provides that shareholders are
not liable for any liabilities of the Trust or any of its sub-trusts, requires
inclusion of a clause to that effect in every agreement entered into by the
Trust or any of its sub-trusts 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 sub-trust on matters affecting an individual
sub-trust. For example, a change in investment policy for a sub-trust would be
voted upon by shareholders of only the sub-trust involved. 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 a
majority of the shares present and voting at such meeting.
 
  The Trustees may amend the Declaration of Trust (including with respect to any
sub-trust) in any manner without shareholder approval, except that the Trustees
may not adopt any amendment adversely affecting the rights of shareholders of
any sub-trust without approval by a majority of the shares of each affected
sub-trust present at a meeting of shareholders (or such higher vote as may be
required by 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 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.
 
  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.
 
                                       B-2
<PAGE>   265
 
   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.)
 
   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.
 
   9. Invest in securities of other investment companies, except as part of a
      merger, consolidation or other acquisition and except that the Fund may
      invest up to 10% of its assets in tax exempt money market funds that
      invest in securities rated comparably to those the Fund may invest in so
      long as the Fund does not own more than 3% of the outstanding voting stock
      of any tax exempt money market fund or securities of any tax exempt money
      market fund aggregating in value more than 5% of the total assets of the
      Fund.
 
  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.
 
  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%.
 
                                       B-3
<PAGE>   266
 
  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 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
 
                                       B-4
<PAGE>   267
 
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 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, 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
 
                                       B-5
<PAGE>   268
 
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 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
 
                                       B-6
<PAGE>   269
 
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
 
                                       B-7
<PAGE>   270
 
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 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-8
<PAGE>   271
 
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 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
 
                                       B-9
<PAGE>   272
 
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 Investment Company Act of 1940 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 high-grade 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 high-grade 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, high-grade assets 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-10
<PAGE>   273
 
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 high-grade 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 Internal Revenue 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
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 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.
 
                                      B-12
<PAGE>   275
 
  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 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
 
                                      B-13
<PAGE>   276
 
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 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
 
                                      B-14
<PAGE>   277
 
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 Standard & Poor's 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;
 
                                      B-15
<PAGE>   278
 
        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 balance, as
    B         predominantly speculative with respect to capacity to pay interest and repay
    CCC       principal. 'BB' indicates the least degree of speculation and 'C' the highest.
    CC        While such debt will likely have some quality and protective characteristics,
    C         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.
 
    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 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).
    
 
                                      B-17
<PAGE>   280
 
        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>
    
 
     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.
</TABLE>
 
                                      B-18
<PAGE>   281
 
   
<TABLE>
    <S>       <C>
    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.
 
    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.
</TABLE>
    
 
     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.
 
                                      B-19
<PAGE>   282
 
          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 senior debt obligations which have an original maturity
     not exceeding one year. Obligations relying upon support mechanisms such as
     letters-of-credit and bond 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 (or supporting institutions) have a superior
        ability for repayment of senior short-term debt obligations.
 
             Issuers rated Prime-2 (or supporting institutions) have a strong
        ability for repayment of senior short-term debt obligations.
 
             Issuers rated Prime-3 (or supporting institutions) have an
        acceptable ability for repayment of senior short-term debt obligations.
 
             Issuers rated Not Prime do not fall within any of the Prime rating
        categories.

* Interested persons of the Fund as defined in the 1940 Act.
 
  Each of the foregoing trustees of the Fund acts as a trustee for other
investment companies advised by the Adviser, and each of the foregoing officers
holds the same positions with other investment companies advised by the Adviser.
 
   
  The compensation of the officers and Trustees who are affiliated persons (as
defined in the 1940 Act) of the Adviser, Van Kampen American Capital
Distributors, Inc. or Van Kampen American Capital, Inc. is paid by the
respective entity. The Fund pays the compensation of all other officers and
Trustees. During the next year, the Fund expects to pay trustees who are not
interested persons of the Adviser, Van Kampen American Capital Distributors,
Inc. or Van Kampen American Capital, Inc., $2,500 per year and $250 per meeting
of the Board of Trustees, plus expenses. Under the Fund's retirement plan,
trustees who are not affiliated with the Adviser, Van Kampen American Capital
Distributors, Inc. or Van Kampen American Capital, Inc., have at least ten years
of service and retire at or after attaining the age of 60, are eligible to
receive a retirement benefit equal to the annual retainer for each of the ten
years following such trustee's retirement. Under certain conditions, reduced
benefits are available for early retirement. Under the Fund's deferred
compensation plan, a trustee who is not affiliated with the Adviser, Van Kampen
American Capital Distributors, Inc. or Van Kampen American Capital, Inc. can
elect to defer receipt of all or a portion of the trustee's fees earned by such
trustee until such trustee's retirement. The deferred compensation earns a rate
of return determined by reference to the Fund or other Van Kampen Merritt mutual
funds advised by the Adviser as selected by the trustee. To the extent permitted
by the Investment Company Act, the Fund may invest in securities of other Van
Kampen Merritt mutual funds advised by the Adviser 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.

(1)     Messrs. Merritt and McDonnell, Trustees of each Fund during fiscal year
      1994, are affiliated persons of the Adviser and are not eligible for
      compensation or retirement benefits from the Funds.
 
(2)     The Registrant is Van Kampen Merritt Tax Free Fund (the "Trust") which
      currently is comprised of 8 sub-trusts, including the Fund. The amounts
      shown in this column are accumulated from the Aggregate Compensation of
      each of these 8 sub-trusts during such sub-trust's last completed fiscal
      year prior to the date of this Statement of Additional Information.
      Beginning in October 1994 each Trustee, except Messrs. Gaughan and Whalen,
      began deferring his entire aggregate compensation paid by the Fund. The
      total combined amount of deferred compensation (including interest)
      accrued with respect to each Trustee as of December 31, 1994 is as
      follows: Mr. Kennedy $14,737; Mr. Miller $14,553; Mr. Nelson $14,737 and
      Mr. Robinson $13,725.
 
(3)     The Retirement Plan commenced as of August 1, 1994 for the Fund. As of
      the end of the Fund's 1994 fiscal year, no amounts had been accrued for
      retirement benefits because such amounts were either zero or considered to
      be immaterial to the net assets of the Fund at such time. During the
      Fund's 1995 fiscal year, the Fund will accrue amounts for retirement
      benefits and include an amount, if any, for such Fund's 1994 fiscal year.
 
(4)     This is the estimated annual benefits payable per year for the 10-year
      period commencing in the year of such Trustee's retirement by a Fund
      assuming: the Trustee has 10 or more years of service on the Board of the
      Fund, retires at or after attaining the age of 60 and the annual retainer
      in the year prior to the Trustee's retirement is $2,500. Trustees retiring
      prior to the age of 60 or with fewer than 10 years of service for the Fund
      may receive reduced retirement benefits from such Fund.
 
(5)     The Fund Complex consists of 20 mutual funds advised by the Adviser. The
      amounts shown in this column are accumulated from the Aggregate
      Compensation of each of these 20 mutual funds in the Fund Complex during
      each fund's last completed fiscal year prior to the date of this Statement
      of Additional Information. The Adviser also serves as investment adviser
      for other mutual funds and closed-end investment companies; however, with
      the exception of Messrs. Merritt, McDonnell and Whalen, such mutual funds
      and closed-end investment companies do not have the same trustees as the
      Fund Complex. Combining the Fund Complex with other mutual funds and
      investment companies advised by the Adviser, Mr. Whalen received Total
      Compensation of $161,850.
 
  As of April 13, 1995, the trustees and officers as a group own less than 1% of
the Shares of the Fund.
 
  No officer or trustee of the Fund owns or would be able to acquire 5% or more

                     INVESTMENT ADVISORY AND OTHER SERVICES
 
  Van Kampen American Capital Investment Advisory Corp. (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's principal office is located at One Parkview Plaza, Oakbrook
Terrace, Illinois 60181. The Adviser is a wholly-owned subsidiary of Van Kampen
American Capital, Inc., which in turn is a wholly-owned subsidiary of VK/AC
Holding, Inc. VK/AC Holding, Inc. is controlled, through the ownership of a
substantial majority of its common stock, by The Clayton & Dubilier Private
Equity Fund IV Limited Partnership ("C&D L.P."), a Connecticut limited
partnership. C&D L.P. is managed by Clayton, Dubilier & Rice, Inc., a New York
based private investment firm. The General Partner of C&D L.P. is Clayton &
Dubilier Associates IV Limited Partnership ("C&D Associates L.P."). The general
partners of C&D Associates L.P. are Joseph L. Rice, III, B. Charles Ames,
William A. Barbe, Alberto Cribiore, Donald J. Gogel, Leon J. Hendrix, Jr.,
Hubbard C. Howe and Andrall E. Pearson each of whom is a principal of Clayton,
Dubilier & Rice, Inc. In addition, certain officers, directors and employees of
Van Kampen American Capital, Inc. own, in the aggregate, not more than 6% of the
common stock of VK/AC Holding, Inc. and have the right to acquire, upon exercise
of options, approximately an additional 10% of the common stock of VK/AC
Holding, Inc.
 
  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 sub-trust, to whom the
Adviser renders periodic reports of the Fund's investment activities.
 
  The investment advisory agreement dated February 17, 1993, was approved by the
shareholders of the Fund at a shareholders meeting held on January 14, 1993.
Accordingly, 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 sub-trust, (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, 1994, 1993 and 1992, the Fund recognized
advisory expenses of $5,028,401, $4,796,312 and $3,877,766, 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 with the other Van Kampen Merritt mutual funds distributed by
the Distributor 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 Merritt funds based proportionally on their respective
net assets.
 
  For the years ended December 31, 1994, 1993 and 1992, the Fund recognized
expenses of approximately $31,650, $19,250 and $18,300, respectively,
representing the Adviser's cost of providing accounting services.
 
  LEGAL SERVICES AGREEMENT. The Fund has entered into a Legal Services Agreement
pursuant to which Van Kampen American Capital, Inc. 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 Fund. 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. The Fund,
and the other Van Kampen Merritt mutual funds distributed by the Distributor,
share one-half (50%) of such costs equally. The remaining one-half (50%) of such
costs are allocated to specific funds based on specific time allocations, or in
the event services are attributable only to types of funds (i.e. closed-end or
open-end), the relative amount of time spent on each type of fund and then
further allocated between funds of that type based upon their respective net
asset values. The Fund has not yet incurred any expenses in connection with this
Agreement.
 
  For the years ended December 31, 1994, 1993 and 1992, the Fund recognized
expenses of approximately $25,100, $22,700 and $11,300, respectively,
representing Van Kampen American Capital, Inc.'s cost of providing legal
services.
 
  SUPPORT SERVICES AGREEMENT. Under a support services agreement with the
Distributor the Fund receives support services for shareholders, including the
handling of all written and telephonic communications, except initial order
entry and other distribution related communications. Upon entering into such
agreement, the Fund realized a reduction in the fee paid to the Transfer Agent.
Payment by the Fund for such services is made on cost basis for the employment
of the personnel and the equipment necessary to render the support services. The
Fund, and the other Van Kampen Merritt mutual funds distributed by the
Distributor, share such costs proportionately among themselves based upon their
respective net asset values.
 
  For the years ended December 31, 1994, 1993 and 1992, the Fund recognized
expenses of approximately $597,765, $423,425 and $359,270, respectively,
representing the Distributor's cost of providing certain support services.
 
                       CUSTODIAN AND INDEPENDENT AUDITORS
 
  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 auditors for the Fund are KPMG Peat Marwick LLP, Chicago,
Illinois. The selection of independent auditors will be subject to ratification
by the shareholders of the Fund at any annual meeting of shareholders.
 
                                      B-25
<PAGE>   288
 
                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 sub-trust.
 
  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 each of its sub-trusts, including the Fund, will be treated as
separate corporations for income tax purposes. The Fund may be subject to tax if
it fails to distribute net capital gains, or if its annual distributions, as a
percentage of its income, are less than the distributions required by tax laws.
 
                                THE DISTRIBUTOR
 
  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 Van Kampen American Capital, Inc., which is a subsidiary of
VK/AC Holding, Inc., a Delaware corporation that is controlled through an
 
                                      B-26
<PAGE>   289
 
ownership of a substantial majority of its common stock, by The Clayton &
Dubilier Private Equity Fund IV Limited Partnership ("C & D L.P."), a
Connecticut limited partnership. In addition, certain officers, directors and
employees of Van Kampen American Capital, Inc., and its subsidiaries own, in the
aggregate not more than 6% of the common stock of VK/AC Holding, Inc. and have
the right to acquire, upon the exercise of options, approximately an additional
10% of the common stock of VK/AC Holding, Inc. C & D L.P. is managed by Clayton,
Dubilier & Rice, Inc. Clayton & Dubilier Associates IV Limited Partnership ("C &
D Associates L.P.") is the general partner of C & D L.P. 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.
 
  The public offering price of Class A Shares for purchasers choosing the
initial sales charge alternative is equal to the net asset value plus an initial
sales charge which is a variable percentage of the offering price depending upon
the amount of the sale. The net asset value will be determined as described in
the Prospectus under "Net Asset Value." It is the responsibility of an investor,
or an investor's broker, dealer or financial intermediary, to promptly forward
payment to the Fund for shares being purchased.
 
  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 Investment
Company Act of 1940. 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, 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 banks 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 banks 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 sub-trust, 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.

the Plans of $2,804,735, $270,245 and $46,842 for the Class A Shares, Class B

Van Kampen Merritt Insured Tax Free Income Fund
- ------------------------------------------------------------------------------

Notes to Financial Statements
December 31, 1994
- ------------------------------------------------------------------------------

1. Significant Accounting Policies
Van Kampen Merritt Insured Tax Free Income Fund (the "Fund") was incorporated
under Maryland law on July 1, 1984, and is registered as a diversified open-end
management investment company under the Investment Company Act of 1940, as
amended. The Fund commenced investment operations on December 14, 1984 and was
reorganized as a sub-trust of Van Kampen Merritt Tax Free Fund (the "Trust"), a
Massachusetts business trust as of February 22, 1988. On May 1, 1993, the Fund
commenced the distribution of its Class B shares. The distribution of the
Fund's Class C shares, which were initially introduced as Class D shares and
subsequently renamed Class C shares on March 7, 1994, commenced on August 13,
1993. The distribution of the Fund's fourth class of shares, Class D shares,
commenced on March 14, 1994.

The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements.


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 less than 60 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" and "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, 1994, the Fund had an accumulated capital loss
carryforward for tax purposes of $12,774 which will expire on December 31, 2001.
Net realized gains or losses may differ for financial and tax reporting purposes
primarily as a result of post October 31 losses which are not recognized for tax
purposes until the first day of the following fiscal year.


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.


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
and facilities to the Fund for an annual fee payable monthly as follows:

<TABLE>
<CAPTION>
Average Net Assets     % Per Annum
- ----------------------------------
<S>                    <C>
First $100 million...  .500 of 1%
Next $150 million....  .450 of 1%
Next $250 million....  .425 of 1%
Over $500 million....  .400 of 1%
</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, 1994, the Fund recognized expenses of
approximately $654,500 representing Van Kampen American Capital Distributors,
Inc.'s or its affiliates' ("VKAC") cost of providing accounting, legal and
certain shareholder services to the Fund.

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, 1994, VKAC owned 100 shares each of Classes B, C and D.

arrangements, including higher distribution and service fees and incremental
transfer agency costs.

received net commissions on sales of the Fund's Class A shares of approximately
$648,100 and CDSC on the redeemed shares of Classes B, C and D of approximately
$56,300. Sales charges do not represent expenses of the Fund.


4. Investment Transactions
Aggregate purchases and cost of sales of investment securities, excluding
short-term notes, for the year ended December 31, 1994, were $588,246,932 and
$656,359,642, 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 for exercised option contracts where
the recognition of gain or loss is postponed until the disposal of the
security underlying the option 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, 1994, 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.

The fluctuation in market value of the contracts is settled daily through a cash
margin account. Realized gains and losses are recognized when the contracts are
closed or expire.

Transactions in futures contracts, each with a par value of $100,000, for the
year ended December 31, 1994, were as follows:


<TABLE>
<CAPTION>

                             ---------  ------------
</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. 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.


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

Annual fees under the Plans of up to .30% each of Class A and Class D shares and
1.00% each of Class B and Class C shares are accrued daily. Included in these
fees for the year ended December 31, 1994, are payments to VKAC of approximately
$512,700.

                             THE FUND AND THE TRUST
 
  The Fund is a separate diversified sub-trust of Van Kampen Merritt Tax Free
Fund (the "Trust"), an open-end diversified management investment company
commonly known as a mutual fund. The Trust is an unincorporated business trust
established under the laws of the Commonwealth of Massachusetts by a Declaration
of Trust dated August 15, 1985. The Declaration of Trust permits the Trustees to
issue an unlimited number of full and fractional shares in separate sub-trusts.
At present, the Fund, Van Kampen Merritt Tax Free High Income Fund, Van Kampen
Merritt Municipal Income Fund, Van Kampen Merritt Insured Tax Free Income Fund,
Van Kampen Merritt Limited Term Municipal Income Fund, Van Kampen Merritt
Florida Insured Tax Free Income Fund, Van Kampen Merritt New Jersey Tax Free
Income Fund and Van Kampen Merritt New York Tax Free Income Fund have been
organized as sub-trusts of the Trust and have commercial investment operations.
Van Kampen Merritt California Tax Free Income Fund, Van Kampen Merritt Michigan
Tax Free Income Fund, Van Kampen Merritt Missouri Tax Free Income Fund and Van
Kampen Merritt Ohio Tax Free Income Fund have been organized as sub-trusts of
the Trust but have not commenced investment operations. Other sub-trusts may be
organized and offered in the future.
 
  Each share of the Trust represents an equal proportionate interest in the
assets of its respective sub-trust with each other share in such sub-trust and
no interest in any other sub-trust. No sub-trust is subject to the liabilities
of any other sub-trust. The Declaration of Trust provides that shareholders are
not liable for any liabilities of the Trust or any of its sub-trusts, requires
inclusion of a clause to that effect in every agreement entered into by the
Trust or any of its sub-trusts 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 sub-trust on matters affecting an individual
sub-trust. For example, a change in investment policy for a sub-trust would be
voted upon by shareholders of only the sub-trust involved. 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 a
majority of the shares present and voting at such meeting.
 
  The Trustees may amend the Declaration of Trust (including with respect to any
sub-trust) in any manner without shareholder approval, except that the Trustees
may not adopt any amendment adversely affecting the rights of shareholders of
any sub-trust without approval by a majority of the shares of each affected
sub-trust present at a meeting of shareholders (or such higher vote as may be
required by 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.

                      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 or any single issuer, except that up to 25% of the Fund's total
      assets may be invested without regard to such limitation.
 
                                       B-2
<PAGE>   314
 
   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.)
 
   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.
 
   9. Invest in securities of other investment companies, except as part of a
      merger, consolidation or other acquisition and except that the Fund may
      invest up to 10% of its assets in tax exempt money market funds that
      invest in securities rated comparably to those in which the Fund may
      invest so long as the Fund does not own more than 3% of the outstanding
      voting stock of any tax exempt money market fund or securities of any tax
      exempt money market fund aggregating in value more than 5% of the total
      assets of the Fund.
 
  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
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%.
 
                                       B-3
<PAGE>   315
 
  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 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
 
                                       B-4
<PAGE>   316
 
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
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, 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
"Taxation."
 
  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
 
                                       B-5
<PAGE>   317
 
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 "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 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
 
                                       B-6
<PAGE>   318
 
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. The case is currently on appeal before
the California Supreme Court. 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.
 
  Because of the complex nature of Articles XIIIA and XIIIB, 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 or XIIIB 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.
 
  Recent Developments. 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, with
 
                                       B-7
<PAGE>   319
 
expenditures exceeding revenues for four of the last five fiscal years ending
with 1991-2 but being essentially equal in 1992-1993. By June 30, 1992, the
State's Fund had a deficit, on a budget basis, of approximately $2.8 billion.
 
  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 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 filed suit against the State alleging that payment of their salaries
with registered warrants violated federal labor laws. See "Litigation" below.
 
  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 termed its outlook as "stable", and Fitch Investors Service
lowered its rating from "AA" to "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.
 
  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 and January, 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).
 
  The Legislature and the Governor were unable to agree on a budget for the
1992-93 fiscal year until September 2, 1992, 64 days after the fiscal year
began. The 1992-93 Budget Act closed a "gap" of about $7.9 billion, but budgeted
a reserve at June 30, 1993 of only $28 million. Shortly after the 1992-93 Budget
Act was enacted, it became evident that economic conditions in the State were
not beginning to improve in the second half of 1992, as assumed by the
Administration's May Revision of economic estimates, which underlay the Budget.
This was exacerbated by enactment of an Initiative measure in November which
reinstated a sales tax exemption for certain candy, snack foods and bottled
water, reducing revenues by about $300 million for a full fiscal year ($200
million in 1992-93). In addition, certain lawsuits were filed concerning
implementation of the K-14 school financing portion of the Budget Act. As part
of this litigation, the State is appealing a Superior Court ruling In California
Teachers Association v. Gould that could cost the State up to $3.0 billion.
 
  The Governor's Budget for 1993-94, confirmed the earlier forecasts about the
State's economy and the 1992-93 Budget. The 1993-94 Budget Act was signed by the
Governor on June 30, 1993, along with implementing legislation. The 1993-94
Budget Act was predicated upon General Fund revenues and transfers estimated at
$40.6 billion and expenditures of $38.5 billion. The 1993-94 Budget Act reflects
several major adjustments. The Budget Act mandates changes in local government
financing to shift about $2.6 billion in property taxes from cities, counties,
special districts and redevelopment agencies to school and community college
districts, thereby reducing the General Fund support by an equal amount. About
$2.5 billion were permanent, reflecting termination of the State's "bail-out" of
local governments following the property tax

cuts of Proposition 13 in 1978. The property tax revenue losses for cities and
counties were offset in part by additional sales tax revenues and mandated
relief. Lawsuits were filed by Los Angeles, Butte, Contra Costa and San Diego
Counties challenging the shift of property taxes mandated by the 1993-1994
Budget Act. A hearing was held on the Los Angeles County case on July 28, 1993
which upheld the constitutionality of the property tax shift. On June 23, 1994,
the California Supreme Court said it would not review Los Angeles County's
petition for review, thus upholding the lower court's decision in favor of the
State. Several additional lawsuits relating to the 1993-1994 and 1994-1995
Budget legislation are still pending. The 1993-94 Budget Act included about $692
million of aid to the State from the federal government to offset health and
welfare costs associated with foreign immigrants living in the State. The Act
also reduced spending for health and welfare programs by $600 million. Overall,
revenues for the 1993-94 Fiscal Year were about $800 million lower than original
projections, and expenditures were about $780 million higher, primarily because
of higher health and welfare caseloads, lower property taxes which required
greater State support for K-14 education to make up the shortfall, and lower
than anticipated federal government payments for immigration-related costs.
 
  By June 30, 1993, according to the Department of Finance, the State's Special
Fund for Economic Uncertainties had a deficit, on a budget basis, of
approximately $2.8 billion. The 1993-94 Budget Act incorporated a Deficit
Retirement Plan to repay this deficit over two fiscal years. The original budget
for 1993-94 reflected revenues which exceeded expenditures by approximately $2.0
billion. As a result of the recession, the excess of revenues over expenditures
for the fiscal year is now expected to be only about $500 million. Thus the
accumulated budget deficit at June 30, 1994 is now estimated by the Department
of Finance to have been approximately $2.0 billion and the deficit will not be
retired by June 30, 1995 as planned. Consequently, the 1994-95 Budget Act
anticipates deferring retirement of about $1 billion of the carryover-budget
deficit to the 1995-96 Fiscal Year, when it is intended to be fully retired by
June 30, 1996.
 
  The 1994-95 Fiscal Year represents the fourth consecutive year the Governor
and the Legislature were faced with a very difficult budget environment to
produce a balanced budget. The 1994-95 Budget Act signed by the Governor on July
8, 1994, is projected to have $41.9 billion of General Fund revenues and
transfers and $40.9 billion of budgeted expenditures. Included in the $41.9
billion revenues figure is a projected receipt of about $360 million from the
federal government to reimburse the State's cost in connection with undocumented
immigrants, most of which was not received. The principal features of the
1994-95 Budget Act also include: (i) reductions of approximately $1.1 billion in
health and welfare costs, and (ii) increase in proposition 98 funding for K-14
schools by $526 million from 1993-94 Fiscal Year levels. A 2.3 percent reduction
in AFDC payments (equal to $52 million for the entire fiscal year) has been
temporarily suspended by court order. Certain health care funding actions of the
Budget Act also were challenged in a court action.
 
  Because preparation of cash flow estimates for the 1995-96 Fiscal Year is
necessarily more imprecise than for the current fiscal year and entails greater
risks of variance from assumptions, and because the Governor's two-year budget
plan assumes receipt of a large amount of federal aid in the 1995-96 Fiscal Year
for immigration-related costs which is uncertain, the Legislature enacted a
backup budget adjustment mechanism that involves a review of the cash flow
projections for the General Fund and a comparison to the projections for the
1994-95 Fiscal Year. This enactment is intended to mitigate possible deviations
from projected revenues, expenditures or internal borrowable resources which
might reduce available cash resources during the two-year plan, so as to assure
repayment of the warrants. Furthermore for the 1995-96 Fiscal Year, additional
legislation prohibits any external borrowing as of June 30, 1996, thereby
requiring the State to rely solely on internal borrowing resources, expenditure
reductions or revenue increases to eliminate any projected cash flow deficit.
 
  On January 17, 1994 an earthquake of the magnitude of an estimated 6.8 on the
Richter Scale struck Los Angeles causing significant damage to public and
private structures and facilities. Although some individuals and businesses
suffered losses totaling in the billions of dollars, the overall effect of the
earthquake on the regional and State economy is not expected to be serious. The
State in conjunction with the federal government is committed to providing
assistance to local governments, individuals and businesses suffering damage as
a result of the earthquake, as well as to providing for the repair and
replacement of State-owned facilities.

  Revised employment data indicate that California's recession ended in 1993,
and following a period of stability, a solid recovery is now underway. The
State's unemployment rate fell sharply last year, from 10.1 percent in January
to 7.7 percent in October and November. The gap between the national and
California jobless rates narrowed from 3.4 percentage points at the beginning of
1994 to an average or 2 percentage points in October and November. The number of
unemployed Californians fell by nearly 400,000 during the year, while civilian
employment increased more than 300,000.
 
  For the first time in four years, the State enters the upcoming fiscal year
with strengthening revenues based on an improving economy. The Governor's
1995-96 Fiscal Year Budget Proposal (the "Proposed Budget") estimates General
Fund revenues and transfers of $42.5 billion (an increase of 0.2 percent over
1994-95). This nominal increase from the 1994-95 Fiscal Year reflects the (i)
Governor's proposed expansion of the realignment program between the State and
counties, so that counties will take on greater responsibility for welfare and
social services, while the State will take on increased funding of trial court
costs and (ii) the first year of a 15% cut on personal income and corporate tax
rates to be phased in over 3 years commencing in 1996. Without these two
proposals, General Fund revenues would be projected at approximately $43.8
billion, or an increase of 3.3 percent over 1994-95. Expenditures are estimated
at $41.7 billion (essentially unchanged from 1994-95).
 
  Budget figures computed by the Controller and the Department of Finance may
differ from each other due to differences in accounting methods and
interpretation. 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 1994-1995 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.
 
  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 180 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 22% 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. The County has technically defaulted upon several of
its outstanding debt issues and its ability to meet its outstanding obligations
is unclear.
 
  The Fund is not presently able to predict whether any other municipalities
will face insolvency because of their participation in the Funds, and if so, the
potential impact on such municipalities' ability to meet its outstanding
obligations. The Governor has called a special session of the Legislature which
is expected to consider various responses to the County situation.
 
  The Mexican currency crisis is expected to have some mild dampening effect on
the California economy; however, it should not endanger the recovery. The peso's
devaluation will make California exports much more expensive in Mexican markets.
Although the economic impact of this is unknown, an export reduction of 20
percent would reduce trade by approximately $1.5 billion. This represents less
than two percent of all exports through California ports. San Diego, however, is
likely to be more severely affected due to substantial reductions in
cross-border traffic. Although the long-run impacts of the devaluation are
unclear, the fundamentals of the Mexican economy are much stronger than during
the last crisis twelve years ago.
 
  Heavy rainfall and widespread flooding throughout the State in mid-January
were at least partially responsible for the slight rise in January unemployment.
However, such flooding is not expected to have a significant impact on the
pattern of economic recovery in California that has been evident over the last
year.
 
  As a part of its cash management program, California regularly issues revenue
anticipation notes ("California notes") and revenue anticipation warrants to
meet cash flow needs during the course of a fiscal
 
                                      B-10

year. On August 21, 1990, California issued $4.1 billion of California notes
which were retired on June 28, 1991. On August 15, 1991, California issued $3.1
billion of fixed rate California notes, which matured and were timely repaid,
and $1.0 billion of variable rate California notes, which matured and were
timely repaid. On October 8, 1992, California issued $5 billion of California
notes, which matured and were paid. The State issued approximately $3.0 billion
of revenue anticipation notes on April 26, 1993, which matured and were repaid
on June 24, 1993, and $2.0 billion of revenue anticipation warrants on June 23,
1993, which matured and were repaid on December 23, 1993. To meet additional
cash flow needs in the 1993-94 Fiscal Year, on July 28, 1993, the State issued
$2.0 billion of revenue anticipation notes maturing on June 28, 1994, and on
February 23, 1994 the State issued $1.2 billion and $2.0 billion of Revenue
Anticipation Warrants maturing on December 21, 1994 and July 26, 1994,
respectively. All such revenue anticipation notes and warrants were timely
repaid. To meet its cash flow needs in the 1994-1995 Fiscal Year, the State has
issued in July and August, 1994, $4.0 billion of revenue anticipation notes
maturing on April 25, 1996 and $3.0 billion of revenue anticipation notes
maturing on June 28, 1995.
 
  On February 10, 1992, a San Diego County Superior Court ruled that the State's
formula for allocating property tax dollars to the State's 58 counties is
unconstitutional and ordered the State Legislature to adopt a more equitable
system by July 1993. This decision has been appealed. In addition, the State is
a party to various litigation which, if one or more cases are decided adversely,
could have a material impact on the State Budget.
 
  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.
 
  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 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.
 
  In the spring of 1991, the Richmond Unified School District ("RUSD") Board of
Directors attempted to end classes six weeks early because of a fiscal crisis.
In response to lawsuits, a lower court judge, in a case called Butt v. State of
California, ordered the State, over objections from the Governor, to provide
funding to allow the school year to be completed, and an emergency loan was
arranged by the State Controller. On appeal, the California Supreme Court in
late December 1992 upheld the lower court's action, ruling that the State
Constitution's guarantee of public education required the State to ensure a full
year's education in all school districts. The Court, however, overturned a
portion of the original order relating to the source of funds
 
                                      B-11
<PAGE>   323
 
for RUSD's emergency loan: the decision leaves unclear just where the State must
find funds to make any future loans of this kind.
 
  In the Yuba River flood litigation, the trial court has found liability in
inverse condemnation and awarded of $500,000 to 12 sample plaintiffs. Potential
liability to the remaining 30 plaintiffs, from claims filed, ranges from $800
million to $1.5 billion. An appeal has been filed.
 
  In Penny Newman v. J.B. Stringfellow, et al., which involves a damage claim of
$850 million arising from contamination at the Stringfellow toxic waste site, a
group of 17 of the 3,800 plaintiffs has received a verdict against the State for
a total of $159,000. The other cases, which have not been litigated, are in the
process of settlement. In a separate suit, United States, People of the State of
California v. J.B. Stringfellow Jr. et al., the State has been found liable by
the District Court on the counterclaim. The amount of liability is still being
litigated.
 
  In Mervin Morris v. Franchise Tax Board, and related issue cases, the State is
a defendant in a lawsuit involving the exclusion of small business stock gains
from preference tax and in some cases, also from taxation. The Franchise Tax
Board now estimates a combined total of approximately $250 million is at issue
in all (court and administrative) cases with the small business stock issue. In
June 1993 the first Court of Appeal decision on this issue was entered (in the
Lennane case) in favor of the Franchise Tax Board. In August 1993 the second
Court of Appeal decision on this issue was entered (in the Morris case) in favor
of the Franchise Tax Board. On December 28, 1994, the California Supreme Court
decided against the State in Lennane; it has taken no action on Morris. The
State will be losing at least $80 million as a result of the decision in
Lennane.
 
  In Parr v. State of California, a complaint was filed in federal court
claiming that payment of wages in registered warrants violated the Fair Labor
Standards Act ("FLSA"). The federal court held that the issuance of registered
warrants does violate the FLSA. In February 1994, Justice Sandra Day O'Connor
refused to block a U.S. magistrate from ordering California to pay $300 million
in penalties. The federal district court issued an order on February 3, 1995
prohibiting the State from further supporting its good faith defense to
liquidated damages, and referred the matter to the magistrate to conduct further
proceedings regarding the damage, if any, to be awarded. The maximum amount of
damage could be approximately $500 million.
 
  Certain cases have been filed with respect to the State's reduction in
payments under the Aid to Families with Dependent Children program. In March
1995, the U.S. Supreme Court upheld a State law limiting certain benefits under
the Aid to Families with Dependent Children program ("AFDC"). In a separate case
decided in February 1995, the U.S. Supreme Court vacated a lower court
injunction on a State law which set lower benefit levels under AFDC for persons
residing in the State for less than one year. The Supreme Court concluded that a
failure to obtain a federal waiver already prevented the State from enacting
such legislation. Anticipated savings from such new law had been estimated at
$22 million annually. The outcome of remaining cases and their ultimate impact
on the State's finances cannot be determined at this time.
 
  The State recently lost several tax refund cases concerning the method of
determining gross insurance premiums involving health insurance. The loss to the
State will be approximately $200 million.
 
  Several lawsuits have been filed by Malibu Video Systems in State and Federal
court to challenge the transfer of moneys from special fund accounts within the
State Treasury to the State's General Fund pursuant to the Budget Acts of 1991,
1992 and 1993. Plaintiffs seek to have the transfers reversed and the moneys,
allegedly totaling approximately $800 million, returned to the special funds.
The State disputes both liability and the amount claimed.
 
  The State is a respondent/defendant in two consolidated cases (American Lung
Association of California v. Wilson; Americans for Nonsmokers' Rights v. State
of California) challenging the purposes of specific appropriations of funds
totaling approximately $65 million for Fiscal Year 1994-95 and approximately $68
million for Fiscal Year 1995-96 from the Cigarette and Tobacco Products Surtax
Fund created by Proposition 99. The petitioners/plaintiffs argue that the funds
can only be used for health education and tobacco-related disease research
programs. The appropriations primarily fund health care services for low-income
persons. On January 23, 1995, the Superior Court issued an interim order in the
consolidated cases prohibiting the State from further encumbering the
specifically appropriated funds and from issuing or negotiating warrants from
the appropriated funds. A final order is expected to be issued after a further
hearing
 
                                      B-12
<PAGE>   324
 
on the remedy to be granted. The effect on the General Fund is unclear. A third
lawsuit challenging the similar appropriations of Proposition 99 funds for
Fiscal Years 1989-90 through 1995-96 has been filed and is pending.
 
  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 constitutional, and to transfer to PERS the 1993-94 and
1994-95 contributions that are unpaid to date. The State defendants have
appealed.
 
  In Jernigan & Burleson v. State, filed in federal district court, the prison
inmate plaintiffs claim they are entitled to minimum wages while working for the
Prison Industry Authority. The inmates claim the State has violated the Fair
Labor Standards Act. Plaintiffs are seeking back pay for the period from August
1990 onward, and liquidated damages, for a total of approximately $350 million.
Both liability and damages are being contested by the State.
 
  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; and (6)
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. In November 1992, the State's voters enacted
an Initiative which reinstated a sales tax exemption for certain candy, snack
foods and bottled water. In November 1993, voters enacted an Initiative which
made permanent a half-cent temporary sales tax which had been scheduled to
expire December 31, 1993. After 1995, the maximum personal income tax rate is
scheduled to return to 9.3 percent from 11 percent, and the AMT rate is
scheduled to drop to 7 percent from 8.5 percent. On November 8, 1994, California
voters approved initiatives relating "three strikes" criminal penalties and
illegal immigrations. The State Controller's report indicated that there was no
anticipated cash impact in the 1994-95 Fiscal Year for such initiatives, but
suggested that budgetary pressure may materialize next year. 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
 
                                      B-13
<PAGE>   325
 
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 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
 
                                      B-14
<PAGE>   326
 
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
 
                                      B-15
<PAGE>   327
 
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 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
 
                                      B-16
<PAGE>   328
 
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 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
 
                                      B-17
<PAGE>   329
 
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 Investment Company Act of 1940 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 high-grade 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 high-grade 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, high-grade assets 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
 
                                      B-18
<PAGE>   330
 
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 high-grade 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 Internal Revenue 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,
 
                                      B-19
<PAGE>   331
 
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 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.
 
                                      B-20
<PAGE>   332
 
  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 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
 
                                      B-21
<PAGE>   333
 
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 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.

                  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 Standard & Poor's 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 balance, as
    B         predominantly speculative with respect to capacity to pay interest and repay
    CCC       principal. 'BB' indicates the least degree of speculation and 'C' the highest.
    CC        While such debt will likely have some quality and protective characteristics,
    C         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-23
<PAGE>   335
 
   
<TABLE>
    <S>       <C>
    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.
 
    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>
    <S>       <C>
    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
    
 
                                      B-25
<PAGE>   337
 
   
     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 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.

    <S>       <C>
    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.
</TABLE>
 
     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 senior debt obligations which have an original maturity
     not exceeding one year. Obligations relying upon support mechanisms such as
     letters-of-credit and bond 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 (or supporting institutions) have a superior
        ability for repayment of senior short-term debt obligations.
 
             Issuers rated Prime-2 (or supporting institutions) have a strong
        ability for repayment of senior short-term debt obligations.
 
             Issuers rated Prime-3 (or supporting institutions) have an
        acceptable ability for repayment of senior short-term debt obligations.
 
          Issuers rated Not Prime do not fall within any of the Prime rating
     categories.

* Interested persons of the Fund as defined in the 1940 Act.
 
  Each of the foregoing trustees of the Fund acts as a trustee for other
investment companies advised by the Adviser, and each of the foregoing officers
holds the same positions with other investment companies of the Adviser.
 
   
  The compensation of the officers and Trustees who are affiliated persons (as
defined in the 1940 Act) of the Adviser, the Distributor or Van Kampen American
Capital, Inc. is paid by the respective entity. The Fund
    
 
                                      B-29

pays the compensation of all other officers and Trustees of the Fund. During the
next year, the Fund expects to pay trustees who are not affiliated persons of
the Adviser, the Distributor or Van Kampen American Capital, Inc., $2,500 per
year and $250 per meeting of the Board of Trustees, plus expenses. Under the
Fund's retirement plan, trustees who are not affiliated with the Adviser, Van
Kampen American Capital Distributors, Inc. or Van Kampen American Capital, Inc.,
have at least ten years of service and retire at or after attaining the age of
60, are eligible to receive a retirement benefit equal to the annual retainer
for each of the ten years following such trustee's retirement. Under certain
conditions, reduced benefits are available for early retirement. Under the
Fund's deferred compensation plan, a trustee who is not affiliated with the
Adviser, Van Kampen American Capital Distributors, Inc. or Van Kampen American
Capital, Inc. can elect to defer receipt of all or a portion of the trustee's
fees earned by such trustee until such trustee's retirement. The deferred
compensation earns a rate of return determined by reference to the Fund or other
Van Kampen Merritt mutual funds advised by the Adviser as selected by the
trustee. To the extent permitted by the Investment Company Act, the Fund may
invest in securities of other Van Kampen Merritt mutual funds advised by the
Adviser 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.

(1)     Messrs. Merritt and McDonnell, Trustees of each Fund during fiscal year
      1994, are affiliated persons of the Adviser and are not eligible for
      compensation or retirement benefits from the Funds.
    
 
   
(2)     The Registrant is Van Kampen Merritt Tax Free Fund (the "Trust") which
      currently is comprised of 8 sub-trusts, including the Fund. The amounts
      shown in this column are accumulated from the Aggregate Compensation of
      each of these 8 sub-trusts during such sub-trust's last completed fiscal
      year prior to the date of this Statement of Additional Information.
      Beginning in October 1994 each Trustee, except Messrs. Gaughan and Whalen,
      began deferring his entire aggregate compensation paid by the Fund. The
      total combined amount of deferred compensation (including interest)
      accrued with respect to each Trustee as of December 31, 1994 is as
      follows: Mr. Kennedy $14,737; Mr. Miller $14,553; Mr. Nelson $14,737 and
      Mr. Robinson $13,725.
    
 
   
(3)     The Retirement Plan commenced as of August 1, 1994 for the Fund. As of
      the end of the Fund's 1994 fiscal year, no amounts had been accrued for
      retirement benefits because such amounts were either zero or considered to
      be immaterial to the net assets of the Fund at such time. During the
      Fund's 1995 fiscal year, the Fund will accrue amounts for retirement
      benefits and include an amount, if any, for such Fund's 1994 fiscal year.
    
 
   
(4)     This is the estimated annual benefits payable per year for the 10-year
      period commencing in the year of such Trustee's retirement by a Fund
      assuming: the Trustee has 10 or more years of service on the Board of the
      Fund, retires at or after attaining the age of 60 and the annual retainer
      in the year prior to the Trustee's retirement is $2,500. Trustees retiring
      prior to the age of 60 or with fewer than 10 years of service for the Fund
      may receive reduced retirement benefits from such Fund.
    
 
   
(5)     The Fund Complex consists of 20 mutual funds advised by the Adviser. The
      amounts shown in this column are accumulated from the Aggregate
      Compensation of each of these 20 mutual funds in the
    
 
                                      B-30

      Fund Complex during each fund's last completed fiscal year prior to the
      date of this Statement of Additional Information. The Adviser also serves
      as investment adviser for other mutual funds and closed-end investment
      companies; however, with the exception of Messrs. Merritt, McDonnell and
      Whalen, such mutual funds and closed-end investment companies do not have
      the same trustees as the Fund Complex. Combining the Fund Complex with
      other mutual funds and investment companies advised by the Adviser, Mr.
      Whalen received Total Compensation of $161,850.
    
 
   
  As of February 13, 1995, the trustees and officers as a group own less than 1%
of the shares of the Fund.
    
 
   
  No officer or trustee of the Fund owns or would be able to acquire 5% or more
of the common stock of VK/AC Holding, Inc.
    
 
   
  The authorized stock of the Fund currently consists of an unlimited number of
full and fractional shares of beneficial interest, without par value.

                                      B-31
<PAGE>   343
 
  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 sub-trust, to whom the
Adviser renders periodic reports of the Fund's investment activities.
 
  The investment advisory agreement was approved by the shareholders of the Fund
at the first shareholders meeting. Accordingly, 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 sub-trust, (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, 1994, 1993 and 1992, the Fund recognized
advisory expenses of $297,611, $196,020 and $72,941, respectively.
    
 
  OTHER AGREEMENTS.
 
   
  FUND ACCOUNTING 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 with the other Van Kampen Merritt mutual funds distributed by
the Distributor, 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 Merritt funds based proportionally on their respective net
assets.
    
 
   
  For the years ended December 31, 1994, 1993 and 1992, the Fund recognized
expenses of approximately $6,600, $4,467 and $2,747, respectively, representing

  SUPPORT SERVICES AGREEMENT. Under a support services agreement with the
Distributor the Fund receives support services for shareholders, including the
handling of all written and telephonic communications, except initial order
entry and other distribution related communications. Upon entering into such
agreement, the Fund realized a reduction in the fee paid to the Transfer Agent.
Payment by the Fund for such services is made on cost basis for the employment
of the personnel and the equipment necessary to render the support services. The
Fund, and the other Van Kampen Merritt mutual funds distributed by the
Distributor, share such costs proportionately among themselves based upon their
respective net asset values.
 
   
  For the years ended December 31, 1994, 1993 and 1992, the Fund recognized

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. The
Fund, and the other Van Kampen Merritt mutual funds distributed by the
Distributor, share one half (50%) of such costs equally. The remaining one half
(50%) of such costs are allocated to specific funds based on specific time
allocations, or in the event services are attributable only to types of funds
(i.e. closed-end or open-end), the relative amount of time spent on each type of
fund and then further allocated between funds of that type based upon their
respective net asset values.
 
   
  For the years ended December 31, 1994, 1993 and 1992, the Fund recognized
expenses of approximately $12,100, $8,900 and $4,300, respectively, representing
Van Kampen American Capital, Inc.'s cost of providing legal services.
    
 
                       CUSTODIAN AND INDEPENDENT AUDITORS
 
  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 auditors for the Fund are KPMG Peat Marwick LLP, Chicago,
Illinois. The selection of independent auditors 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 sub-trust.
 
                                      B-33
<PAGE>   345
 
   
  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 each of its sub-trusts, including the Fund, will be treated as
separate corporations for income tax purposes. The Fund may be subject to tax if
it fails to distribute net capital gains, or if its annual distributions, as a
percentage of its income, are less than the distributions required by tax laws.
 
                                THE DISTRIBUTOR
 
  Shares of the Fund are offered on a continuous basis through Van Kampen
American Capital Distributors, Inc., One Parkview Plaza, Oakbrook Terrace, IL
60181. Van Kampen American Capital Distributors, Inc. is a wholly owned
subsidiary of Van Kampen American Capital, Inc., which is a subsidiary of VK/AC
Holding, Inc., a Delaware corporation that is controlled through an ownership of
a substantial majority of its common stock, by The Clayton & Dubilier Private
Equity Fund IV Limited Partnership ("C & D L.P."), a Connecticut limited
partnership. In addition, certain officers, directors and employees of Van
Kampen American Capital, Inc., and its subsidiaries own, in the aggregate not
more than 6% of the common stock of VK/AC Holding, Inc. and have the right to
acquire, upon the exercise of options, approximately an additional 10% of the
common stock of VK/AC Holding, Inc. C & D L.P. is managed by Clayton, Dubilier &
Rice, Inc. Clayton & Dubilier Associates IV Limited Partnership ("C & D
Associates L.P.") is the general partner of C & D L.P. 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.
 
  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 Investment
Company Act of 1940. 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, 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 banks 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 banks 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 and/or Selling Agreement. To
the extent that there remain outstanding shares of the Fund
 
                                      B-34
<PAGE>   346
 
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 sub-trust, 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 year ended December 31, 1994, the Fund has recognized expenses under
the Plans of $434,452, $177,806 and $42,705 for the Class A Shares, Class B
Shares and Class C Shares, respectively, of which $334,597 and $44,221 represent
payments to financial intermediaries under the Selling Agreements for Class A
Shares and Class B Shares, respectively. For the year ended December 31, 1994,
the Fund has reimbursed the Distributor $51,734 and $3,111 for advertising
expenses, and $21,356 and $5,827 for compensation of the Distributor sales
personnel for the Class A Shares and Class B Shares, respectively.

  Counsel to the Fund is Skadden, Arps, Slate, Meagher & Flom, Chicago,

Notes to Financial Statements
December 31, 1994
- --------------------------------------------------------------------------------

1.Significant Accounting Policies

Van Kampen Merritt California Insured Tax Free Fund (the "Fund") was
organized as a subtrust of the Van Kampen Merritt Tax Free Fund, a
Massachusetts business trust, on August 15, 1985, and is registered as 
a diversified open-end management investment company under the
Investment Company Act of 1940, as amended. The Fund commenced
investment operations on December 13, 1985. The distribution of the
Fund's Class B shares and Class C shares, which were initially 
introduced as Class D shares and subsequently renamed Class C shares 
on March 7, 1994, 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.


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 less than 60 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" and "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,
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, 1994, the Fund had an accumulated capital loss 
carryforward for tax purposes of $6,845,254. Of this amount, $100,459,
$1,014,876, $105,997 and $5,623,922 will expire on December 31, 1995, 1996,
2001, and 2002, respectively. Net realized gains or losses may differ for
financial and tax reporting purposes primarily as a result of post October 31
losses which are not recognized for tax purposes until the first day of the
following fiscal year.


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.


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:

to the Fund, of which a trustee of the Fund is an affiliated person.

year of the purchase for Class C as detailed in the following schedule. The
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.

4.Investment Transactions

Aggregate purchases and cost of sales of investment securities, excluding 
short-term notes, for the year ended December 31, 1994 were $91,001,472 and
$100,884,986, 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.

Summarized below are the specific types of derivative financial instruments used
by the Fund.


A. 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.

The fluctuation in market value of the contracts is settled daily through a cash
margin account. Realized gains and losses are recognized when the contracts are
closed or expire.

Transactions in futures contracts, each with a par value of $100,000, for the
year ended December 31, 1994, 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. 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.


6.Distribution and Service Plans

The Fund and its shareholders have adopted a distribution plan (the 
"Distribution Plan") pursuant to Rule 12b-1 under the Investment Company Act of
1940 and a service plan (the "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 .30% of Class A shares and 1.00% each of
Class B and Class C shares are accrued daily. Included in these fees for the
year ended December 31, 1994, are payments to VKAC of approximately $245,200.

                       LIMITED TERM MUNICIPAL INCOME FUND
 
    Van Kampen Merritt Limited Term Municipal Income Fund (the "Fund") is a
separate diversified sub-trust of Van Kampen Merritt Tax Free Fund, an open-end
management investment company, commonly known as a mutual fund. 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 will seek
to achieve its investment objective by investing substantially all of its 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 or Baa or higher by Moody's Investors
Service (or comparably rated by any other nationally recognized statistical
ratings organization). The Fund does not intend to invest in unrated municipal
securities. Under current market conditions, the Fund anticipates that it will
limit the dollar-weighted average life of its portfolio to between 10 and 15
years. 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." The
Fund may invest a substantial portion of its assets in municipal securities that
pay interest that is subject to the alternative minimum tax. There is no
assurance that the Fund will achieve its investment objective.

    The Fund's investment adviser is Van Kampen American Capital Investment
Advisory Corp. This Prospectus sets forth certain information about the Fund
that a prospective investor should know before investing in the Fund. Please
read it carefully and retain it for future reference. The address of the Fund is
One Parkview Plaza, Oakbrook Terrace, Illinois 60181, and its telephone number
is 1-800-225-2222, ext 6504.
 
    The Fund is offering three classes of its shares (the "Alternative Sales
Arrangements") 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 (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"). 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.
 
   
    Each class of shares pays ongoing distribution and service fees at an
aggregate annual rate of (i) for Class A Shares, up to 0.30% of the Fund's
average daily net assets attributable to the Class A Shares, (ii) for Class B
Shares, up to 1.00% of the Fund's average daily net assets attributable to the
Class B Shares and (iii) for Class C Shares up to 1.00% of the Fund's average
daily net assets attributable to the Class C Shares. Investors should understand
that the purpose and function of the deferred sales charge and the distribution
and service fees with respect to the Class A Share accounts over $1 million,
Class B Shares and the Class C Shares are the same as those of the initial sales
charge and distribution and service fees with respect to the Class A Shares
accounts below $1 million. Each share of the Fund represents an identical
interest in the investment portfolio of the Fund and has the same rights, except
that (i) each class of shares bears those distribution fees, service fees and
administrative expenses applicable to the respective class of shares as a result
of its sales arrangements, which will cause the different classes of shares to
have different expense ratios and to pay different rates of dividends, (ii) each
class 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) the
classes have different exchange privileges. Class B Shares will automatically
convert to Class A Shares six 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. The purpose of the
conversion feature is to relieve the holders of Class B Shares for such six year
period from the higher aggregate distribution and service fees applicable to
Class B Shares. See "Purchasing Shares of the Fund."

                               PROSPECTUS SUMMARY
- --------------------------------------------------------------------------------
 
THE FUND  Van Kampen Merritt Limited Term Municipal Income Fund (the "Fund") is
a separate diversified sub-trust of Van Kampen Merritt Tax Free Fund, which is
an open-end management investment company organized as a Massachusetts business
trust. See "The Fund."
 
INVESTMENT OBJECTIVE AND POLICIES  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 will seek to achieve its investment objective
by investing substantially all of its 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). The Fund does not intend to invest in unrated municipal
securities. Under current market conditions, the Fund anticipates that it will
limit the dollar-weighted average life of its portfolio to between 10 and 15
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 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."
 
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
 
                                        4
<PAGE>   364
 
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 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 $1,000,000 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.
    
 
  The minimum initial investment with respect to each of the Class A Shares,
Class B Shares and Class C Shares is $1,000. The minimum subsequent investment
with respect to each class of shares is $100.
 
   
  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 0.30% 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 contingent deferred sales charge.
    
 
  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 contingent deferred sales
charge 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 will convert to Class A Shares six 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, but are subject to a sales charge if redeemed within the first year
after purchase. Class C Shares are subject to a contingent deferred sales charge
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.
 
   
INVESTMENT ADVISER AND ADVISORY FEE  Van Kampen American Capital Investment
Advisory Corp. (the "Adviser") is the investment adviser for the Fund. The
annual advisory fee for the Fund is 0.50% of its average daily net assets,
reduced on net assets over certain amounts. See "Investment Advisory Services."
    
 
DISTRIBUTIONS FROM THE FUND  Distributions from net investment income are
declared daily and paid monthly; net realized capital gains, if any, are
distributed annually.

<PAGE>   365
 
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."
 
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."
 
    The above is qualified in its entirety by reference to the more detailed
              information appearing elsewhere in this Prospectus.

You would pay the following expenses on a
  $1,000 investment, assuming (i) an
  operating expense ratio of 0.67% for
  Class A Shares, 1.43% for Class B Shares
  and 1.43% for Class C Shares (ii) 5%
  annual return and (iii) redemption at the
  end of each time period:
  Class A Shares...........................  $  39    $ 53    $ 69    $  113
  Class B Shares...........................  $  45    $ 65    $ 78    $  132
  Class C Shares...........................  $  25    $ 45    $ 78    $  171
An investor would pay the following
  expenses on the same $1,000 investment
  assuming no redemption at the end of each
  period:
  Class A Shares...........................  $  39    $ 53    $ 69    $  113
  Class B Shares...........................  $  15    $ 45    $ 78    $  132
  Class C Shares...........................  $  15    $ 45    $ 78    $  171
</TABLE>
    
 
  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. 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 "Investment Advisory Services" and "The Distribution and Service
Plans."

THE FUND
- --------------------------------------------------------------------------------
 
  Van Kampen Merritt Limited Term Municipal Income Fund (the "Fund") is a
separate diversified sub-trust of Van Kampen Merritt Tax Free Fund (the
"Trust"), which is an open-end management investment company, commonly known as
a "mutual fund," organized as a Massachusetts 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. Investment in the Fund involves
special considerations as the Fund is a newly organized investment company with
no history of investment operations.
 
   
  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 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 substantially
all of its assets in a diversified portfolio of municipal securities rated
investment grade at the time of investment. The Fund does not intend to invest
in unrated municipal securities. Under current market conditions, the Fund
anticipates that it will limit the dollar-weighted average life of its portfolio
to between 10 and 15 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."
 
  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) in the case of long-term obligations, and have equivalent
ratings in the case of short-term 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,
 
                                       11
<PAGE>   371
 
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 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
nationally recognized statistical rating organization) 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 nationally recognized statistical rating
organizations. Securities rated below investment grade commonly are referred to
as "junk bonds" and are regarded by S&P and Moody's as predominantly speculative
with respect to the capacity to pay interest and/or repay principal in
accordance with their terms.
 
  Under current market conditions, the Fund anticipates that it will limit the
dollar-weighted average life of its portfolio to between 10 and 15 years.
Generally, a portfolio of municipal securities having a longer dollar-weighted
average life tends to produce a higher level of income than a portfolio of
municipal securities having a shorter dollar-weighted average life, although
such differences cannot be assured. Under current market conditions, however,
the incremental yield-to-maturity difference between municipal securities with
longer maturities and municipal securities with shorter maturities tends to be
less than historic norms. In addition, market prices of municipal securities
with longer maturities generally fluctuate more in response to changes in
interest rates than do market prices of municipal securities with shorter
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 10 to 15 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 10 to 15 years, the Board
of Trustees of the Fund, 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.

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 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
 
                                       13
<PAGE>   373
 
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, 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.
 
  Although 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 security
experiencing non-payment and a potential decrease in the net asset value of the
Fund.
 
  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 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
 
                                       14
<PAGE>   374
 
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 nationally recognized statistical
rating organization); commercial paper rated in the highest grade by either
rating service (or comparably rated by any other nationally recognized
statistical rating organization); 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 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
 
                                       15
<PAGE>   375
 
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.
 
  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
    
 
                                       16
<PAGE>   376
 
   
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 high-grade
municipal portfolio 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. 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
 
                                       17
<PAGE>   377
 
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
(the "Investment Company Act"). See "Investment Policies and Restrictions" in
the Statement of Additional Information.
 
- --------------------------------------------------------------------------------
PURCHASING SHARES OF THE FUND
- --------------------------------------------------------------------------------
 
  The Fund currently offers three classes of shares to the public on a
continuous basis through Van Kampen American Capital Distributors, Inc. (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") who are acting
as securities dealers ("dealers") and through NASD members or eligible non-NASD
members who are acting as brokers or agents for investors ("brokers"). The Fund
reserves the right to suspend or terminate the continuous public offering at any
time and without prior notice.
 
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 fees with respect to each class of shares that may be incurred over
the anticipated duration of their investment in the Fund.
 
                                       18
<PAGE>   378
 
   
  The Fund currently 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
$1,000,000 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 $1,000.
The minimum subsequent investment with respect to each class of shares is $100.
It is presently the policy of the Distributor, not to accept any order for Class
B Shares or Class C Shares in an amount of $1,000,000 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). Investors who intend to hold their shares for a
significantly long time may not wish to continue to bear the ongoing
distribution and service expenses of Class C Shares which in the aggregate,
eventually would exceed the aggregate amount of initial sales charge and
distribution and service expenses applicable to Class A Shares, irrespective of
the fact that a CDSC would eventually not apply to a redemption of such Class C
Shares.
 
  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. Only the Class B Shares are subject to
a
 
                                       19
<PAGE>   379
 
conversion feature (discussed below). Generally, a class of shares subject to a
higher ongoing distribution fee, service fee or, where applicable, the
conversion feature will have a higher expense ratio and pay lower dividends than
a class of shares subject to a lower ongoing distribution fee, 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 "Net Asset Value."
 
  The administrative expenses that may be allocated to a specific class of
shares may consist of (i) transfer agency 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 "Commission") 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 that shall be approved by
the Commission pursuant to an amended exemptive order. 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 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
securities 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. See "Net Asset Value."
 
  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
 
                                       20
<PAGE>   380
 
   
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. 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. In addition, 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 are made
by the Distributor out of its own assets, and not out of the assets of the Fund.
These programs will not change the price an investor will pay for shares or the
amount that the Fund will receive from such sale.
    
 
INITIAL SALES CHARGE ALTERNATIVE
 
  Investors choosing the initial sales charge alternative purchase 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 an 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 Securities and Exchange Commission has
taken the 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.

* No sales charge is payable at the time of purchase on investments of
  $1,000,000 or more, although for such investments the Fund imposes a
  contingent deferred sales charge 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 million, plus 0.20% on

  the next $2 million and 0.08% on the excess over $5 million. See "Purchasing
  Shares Of The Fund -- Deferred Sales Charge Alternatives" for additional
  information with respect to contingent deferred sales charges.
 
  QUANTITY DISCOUNTS. Purchasers of Class A Shares may be entitled to reduced
initial sales charges through a combination of investments, rights of
accumulation or a Letter of Intent (even if investors are not currently making
an investment of a size that would normally qualify for a quantity discount).
Investors, or their broker, dealer or financial intermediary, 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.
 
  For purposes of determining whether a purchase qualifies for a reduced initial
sales charge, the term "any person" is defined as any one of the following:
 
     (i) an individual, their spouse and children under the age of 21, trust or
         custodial accounts established for any of their sole benefit(s) and any
         corporation, partnership or sole proprietorship which is 100% owned,
         either alone or in combination, by any of the foregoing; or
 
    (ii) a trustee or other fiduciary purchasing for a single trust estate
         (including a pension, profit-sharing or other employee benefit trust
         created pursuant to a plan qualified under Section 401 of the Internal
         Revenue Code, as amended); or
 
   (iii) a "company" as defined in Section 2(a)(8) of the Investment Company
         Act.
 
  1. Combination of Investments. Purchases of Class A Shares of the Fund, or
shares of Van Kampen Merritt other funds distributed by the Distributor subject
to an initial sales charge ("ISC Shares"), which are made at any one time by
"any person" may be combined to receive a quantity discount.
 
  2. Rights of Accumulation. Under the rights of accumulation, in determining
the sales charge to be paid for a current purchase of Class A Shares, "any
person" (as defined above) may combine their current purchase with the current
public offering price of Class A Shares of the Fund or ISC Shares, which are
owned by such person. If the account an investor is combining for rights of
accumulation differs from the account into which the investor's current purchase
is placed, the investor must indicate to the Transfer Agent the account number
(and, if applicable, fund name) of such other account.
 
  3. Letter of Intent. Purchasers of Class A Shares may qualify immediately for
a reduced sales charge by stating their intention to purchase an amount of Class
A Shares, during a 13 month period, that would qualify the investor for a
reduced sales charge. An investor may do this by signing a nonbinding Letter of
Intent, which may be signed at any time within 90 days after the first
investment to be included under the Letter of Intent. Class A Shares purchased
under the "Rights of Accumulation" described above (including investments in ISC
Shares) may be, at the time of the signing of the Letter of Intent,
 
                                       22
<PAGE>   382
 
applied towards completion of an investor's Letter of Intent. In addition, if an
investor's broker, dealer or financial intermediary and the Distributor agree to
refund the appropriate portion of their respective concessions to the Fund, the
sales charge on an investor's previous purchases made within 90 days may be
adjusted to the reduced sales charge under the Letter of Intent, and the
refunded concession will be used to purchase shares of the Fund or funds at the
public offering price next determined after receipt of such monies. Each
investment made after signing the Letter of Intent will be entitled to the
initial sales charge applicable to the total investment indicated in the Letter
of Intent. If an investor does not complete the necessary purchases under the
Letter of Intent within 13 months from the date of the first purchase included
thereunder, the sales charge will be adjusted upward, corresponding to the
amount actually purchased.
 
  When an investor signs a Letter of Intent, Class A Shares of the Fund
purchased with a value of 5% of the amount specified in the Letter of Intent
will be restricted; that is, these Class A Shares cannot be sold or redeemed
until the Letter of Intent is satisfied or the additional sales charges have
been paid. If the total purchases made under the Letter of Intent, less
redemptions, equal or exceed the amount specified in the Letter of Intent, these
Class A Shares will no longer be restricted. If the total purchases, less
redemptions, exceed the amount so specified, and qualify an investor for a
further quantity discount, the Distributor and the investor's securities broker,
dealer or financial intermediary will, upon request, remit their respective
portions of the sales concession and with that amount, purchase additional Class
A Shares of the Fund for the investor's account at the next determined public
offering price. If an investor does not complete the necessary purchases under
the Letter of Intent, the sales charges will be adjusted upward and if, after
written notice, the investor does not pay the increased sales charge, sufficient
restricted Class A Shares will be redeemed to pay such charge.
 
  OTHER PURCHASE PROGRAMS. Purchasers of Class A Shares may be entitled to
reduced initial sales charges in connection with unit 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.
 
  1. Unit Trust Reinvestment Programs. The Fund permits unitholders of unit
investment trusts to reinvest distributions from such trusts in Class A Shares
of the Fund and other ISC Shares with no minimum initial or subsequent
investment requirement, and with a lower sales charge 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
investments made from unit trust distributions will be 1% of the offering price
(1.01% of net asset value). Of this amount, the Distributor will pay to the
dealer or broker, 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 securities broker or dealer or the Distributor.
 
                                       23
<PAGE>   383
 
  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 the Fund's transfer agent with
appropriate backup data for each participating investor in a computerized format
fully compatible with the transfer agent's 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.
    
 
2. NAV Purchase Options
 
  The classes of investors entitled to purchase shares of the Fund at net asset
value are as follows:
 
 (a) Current or retired Trustees/Directors of funds advised by Van Kampen
     American Capital Investment Advisory Corp., Van Kampen American Capital
     Asset Management, Inc. or John Govett & Co. Limited and such persons'
     families and their beneficial accounts. The term "families" includes a
     person's spouse, children and grandchildren, parents, and a person's
     spouse's parents.
 
 (b) Current or retired directors, officers and employees of VK/AC Holdings,
     Inc. and any of its subsidiaries, Clayton, Dubilier & Rice, Inc., employees
     of an investment subadviser to any such fund or an affiliate of such
     subadviser; and such persons' families and their beneficial accounts.
 
 (c) Directors, officers, employees and registered representatives of financial
     institutions that have a selling agreement with the Distributor and their
     spouses and minor children 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.
 
   
 (d) 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 the Fund alone, or in any combination of
     Class A Shares of the Fund and ISC Shares of other funds distributed by the
     Distributor as described herein under "Purchasing Shares Of The Fund --
     Initial Sales Charge Alternative -- Quantity Discounts," during the 13
     month period commencing with the first investment pursuant hereto equals at
     least $1 million. The Distributor may pay such entities through which
     purchases are made an amount up to 0.50% of the amount invested, over a
     twelve month period following such transaction.
    
 
                                       24
<PAGE>   384
 
 (e) Trustees and other fiduciaries purchasing shares for retirement plans of
     organizations with retirement plan assets of $10 million or more. The
     Distributor may pay commissions of up to 1% for such purchases.
 
 (f) Accounts as to which a selling firm charges an account management fee
     ("wrap accounts"), provided the selling firm has executed a supplemental
     agreement to their existing selling agreement with the Distributor.
 
 (g) 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.
 
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 being 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 other financial
intermediaries, which percentage rate will be equal to (i) 1.00% with respect to
Class A Shares in an amount of $1 million or more; (ii) 3.00% with respect to
Class B Shares; and (iii) 1.00% with respect to Class C Shares, except that the
Distributor may from time to time compensate such brokers, dealers or financial
intermediaries at a rate of 3.0% of the dollar value of such Class B Shares.
Such compensation will not change the price an investor will pay for Class B
Shares or the amount that the Fund will receive from such sale. Sales
compensation with respect to Class A Shares subject to a CDSC is set forth under
"Purchasing Shares of the Fund -- Initial Sales Charge Alternative".
 
  CDSC Shares redeemed within a specified period of time generally will be
subject to a contingent deferred sales charge at the rates set forth below
charged as a percentage of the dollar amount subject thereto. The amount of the
contingent deferred sales charge 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 such charge
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.
 
                                       25
<PAGE>   385
 
  Proceeds from the contingent deferred sales charge 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 contingent deferred sales charge and the
distribution and service 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 contingent deferred sales change 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 contingent deferred sales charge 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, if any, and fourth of CDSC Shares held
longest during the period of time that a contingent deferred sales charge 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 proceeds will be charged at a rate of 2.5% (the
applicable rate in the second year after purchase).
 
  The contingent deferred sales charge is waived (i) on a redemption of shares
following the death of a shareholder, or (ii) to the extent that the redemption
represents a minimum required distribution from an IRA or other retirement plan
to a shareholder who has attained the age of 70 1/2.
 
   
  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 $1,000,000 or more,
although for such investments the Fund imposes a contingent deferred sales
charge 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 million, plus 0.20% on the next $2 million and 0.08% on the
excess over $5 million.

  CLASS B SHARES.  Class B Shares redeemed within four years of purchase
generally will be subject to a contingent deferred sales charge at the rates set
forth below, charged as a percentage of the dollar amount subject thereto:

</TABLE>
 
  The contingent deferred sales charge generally is waived on redemptions of
Class B Shares made pursuant to the Systematic Withdrawal Program. See
"Shareholder Programs -- Systematic Withdrawal Program."
 
  CLASS C SHARES. Class C Shares redeemed within the first twelve months of
purchase generally will be subject to a contingent deferred sales charge 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. Six years after the end of the month in which a
shareholder's order to purchase a Class B Share was accepted, such Class B Share
automatically will convert to Class A Shares and will no longer be subject to
the higher distribution fee applicable to Class B Shares. The purpose of the
conversion feature is to relieve the holders of Class B Shares for such six year
period from the higher aggregate distribution and service fees applicable to
Class B Shares. Proceeds received by the Distributor from the distribution fee
and the contingent deferred sales charge, if any, with respect to a particular
Class B Share may be more or less than the Distributor's actual distribution
related expense with respect to such Class B Share. The Fund does not expect to
issue any stock certificates upon conversion.
 
  For purposes of conversion of Class A Shares, Class B Shares purchased through
the reinvestment of dividends and distributions paid in respect of Class B
Shares in a shareholder's account will be considered to be held in a separate
sub-account. Each time any Class B Shares in the shareholder's account (other
than those in the sub-account) convert to Class A Shares, an equal pro rata
portion of the Class B Shares in the sub-account also will convert to Class A
Shares. The holding period applicable to the Class B Shares acquired through the
use of the exchange privilege (discussed below) shall be the holding period
applicable to a Class B Share of such Fund acquired other than through use of
the exchange privilege. For purposes of calculating the holding period
applicable to a Class B Share of the Fund prior to conversion, a Class B Share
of the Fund issued in connection with an exercise of the exchange privilege, or
a series of exchanges, shall be deemed to have been issued on the date on which
the investor's order to purchase the
 
                                       27
<PAGE>   387
 
exchanged Class B Shares was accepted or, in the case of a series of exchanges,
when the investor's order to purchase the original Class B Share was accepted.
 
  The conversion of Class B 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 transfer agency costs
with respect to Class B Shares does not result in the Fund's dividends or
distributions constituting "preferential dividends" under the Internal Revenue
Code of 1986, as amended, and (ii) the conversion of Class B Shares does not
constitute a taxable event under federal income tax law. The conversion of Class
B Shares to Class A Shares may be suspended if such an opinion is no longer
available. In that event, no further conversions of Class B Shares would occur,
and Class B Shares might continue to be subject to the higher aggregate
distribution and service fees for an indefinite period, which period may extend
beyond the period ending six years after the end of the month in which the
shares were issued.
 
- --------------------------------------------------------------------------------
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, 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 the Fund's transfer agent receives payments for such shares.
However, shares become entitled to dividends on the day the Fund's transfer
agent 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 information under the "Distributions" section of the
Account Application bound in this Prospectus or available from State Street Bank
and Trust Company, c/o National Financial Data Services, Van Kampen Merritt
Funds, P.O. Box 419001,

Kansas City, MO 64141-6001 (the "Transfer Agent"). After the Transfer Agent
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 to the Transfer Agent. This election may be made by telephone by
calling 1-800-341-2911 or in writing to the Transfer Agent. For inquiries
through Telecommunications Device for the Deaf (TDD), dial 1-800-772-8889,
during the hours of 7:30 a.m. to 4:00 p.m. Central Standard Time. If a
shareholder elects to change the method of distribution, such change will be
effective only with regard to distributions for which the record date is seven
or more business days after the Transfer Agent has received the request.
 
- --------------------------------------------------------------------------------
REDEMPTION OF SHARES
- --------------------------------------------------------------------------------
 
  WRITTEN REDEMPTION REQUEST. Shareholders may sell shares without charge (other
than, with respect to the CDSC Shares, any applicable contingent deferred sales
charge) at any time by mailing a written redemption request in proper form to
the Transfer Agent. This request should be sent to State Street Bank and Trust
Company, c/o National Financial Data Services, Van Kampen Merritt Funds, P.O.
Box 419001, Kansas City, MO 64141-6001. The request should indicate the number
of shares to be redeemed of a particular fund and the class designations of such
shares, identify the account number and be signed exactly as the shares are
registered. If the amount being redeemed is in excess of $50,000 or if the
redemption proceeds will be sent to an address other than the address of record,
the signature(s) must be guaranteed by a member firm of a principal stock
exchange, a commercial bank or trust company which is a member of the Federal
Deposit Insurance Corporation, a credit union or a savings association. The
guarantee must state the words "Signature Guaranteed" along with the name of the
granting institution. Shareholders should verify with the institution that it is
an eligible guarantor prior to signing. A guarantee from a notary public is not
acceptable. If certificates are held for the shares being redeemed, such
certificates must be sent and endorsed for transfer or accompanied by an
endorsed stock power. Share certificates should be sent by registered mail to
National Financial Data Services, 1004 Baltimore Avenue, Dwight Building, Sixth
Floor, Kansas City, MO 64105-1807. Shareholders will receive the net asset value
per share next computed after the Transfer Agent receives the redemption request
and certificates (if any) in proper form. Any applicable contingent deferred
sales charge with respect to CDSC Shares redeemed will be deducted from the
redemption proceeds prior to transmittal of such proceeds to the shareholder.
 
   
  TELEPHONE REDEMPTIONS. Shareholders may sell shares by calling the Fund at
1-800-341-2911 before 3:00 p.m. Central Standard Time to request a redemption by
the Fund. For inquiries through Telecommunications Device for the Deaf (TDD),
dial 1-800-772-8889, during the hours of 7:30 a.m. to 3:00 p.m. Central Standard
Time. There is a $500 minimum and a $1,000,000 maximum per request if the
redemption proceeds are to be
    
 
                                       29
<PAGE>   389
 
mailed to the shareholder. If the redemption proceeds are to be wired to a bank
there is a minimum of $5,000 and a $1,000,000 maximum per request. Prior to
redeeming shares by telephone the "Expedited Telephone Redemption" section of
either the Account Application or Expedited Telephone Redemption and Exchange
Request Form (the "Authorization") must be completed and on file with the
Transfer Agent. The signature(s) on the Authorization must be guaranteed by a
member firm of a principal stock exchange, a commercial bank or trust company
which is a member of the Federal Deposit Insurance Corporation, a credit union
or a savings association unless the Authorization is completed at the time an
account is originally established. The guarantee must state the words "Signature
Guaranteed" along with the name of the granting institution. Shareholders should
verify with the institution that it is an eligible guarantor prior to signing. A
guarantee from a notary public is not acceptable. A redemption requested by
telephone will be processed at the net asset value next determined after receipt
of the request. Any applicable contingent deferred sales charge with respect to
CDSC Shares redeemed will be deducted from the redemption proceeds prior to
transmittal of such proceeds to the shareholder. The proceeds would then be made
payable to the registered shareowner(s) and mailed to the address registered on
the account or wired to a bank, as requested on the Authorizations. Shareholders
cannot redeem shares by telephone if stock certificates are held for those
shares. This service is not available with respect to shares held in an
Individual Retirement Account for which State Street Bank and Trust Company acts
as custodian. In addition, this service is not available with respect to shares
purchased by check until 15 days after purchase.
 
  By establishing the telephone redemption service, a shareholder authorizes the
Fund or the Transfer Agent to act upon the instructions of any person by
telephone to redeem shares for any account for which such service has been
authorized to the address of record of such account or such other address as is
listed in the Authorization. The Fund, the Distributor, the Transfer Agent and
National Financial Data Services ("NFDS") seek to employ procedures reasonably
believed to confirm that instructions communicated by telephone are genuine.
Such procedures include requiring an investor attempting to redeem shares by
telephone to provide, on a recorded line, the name of the account, a social
security or tax identification number and such additional information as may be
included in the Authorization. An investor agrees that no such person will be
liable for any loss, liability, cost or expense arising out of any request
reasonably believed to be genuine, including any fraudulent or unauthorized
request. This service may be amended or terminated at any time by the Transfer
Agent or the Fund. If a shareholder is unable to reach the Fund by telephone, he
or she may redeem shares pursuant to the procedures set forth above under the
caption "Written Redemption Request." During periods of extreme economic or
market changes, it may be difficult for investors to reach the Fund by telephone
and to effect telephone redemptions.
 
  REDEMPTION THROUGH DEALERS. Shareholders may sell shares (whether in
certificate or book-entry form) through their securities dealer, who will
telephone the request to the Distributor. Shareholders will receive the net
asset value next determined after such shareholder places the sell order. Any
applicable contingent deferred sales charge with respect to CDSC Shares redeemed
will be deducted from the redemption proceeds prior
 
                                       30
<PAGE>   390
 
to transmittal of such proceeds to the shareholder. It is the responsibility of
the investor's broker, dealer or financial intermediary to transmit the
redemption order to the Distributor. Because the Fund generally will determine
net asset value once each business day as of the close of business, sell 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
redemption price due to the failure of the Distributor to receive a sell order
prior to such time must be settled between the investor and the broker, dealer
or financial intermediary submitting the order. The Fund does not charge for
this transaction (other than any contingent deferred sales charge applicable to
CDSC Shares). Shareholders must submit a written redemption request in proper
form to their securities dealer within five business days after calling the
dealer with the sell order. The request should indicate the number of shares to
be redeemed and the class designation of such shares, identify the account
number and the order or confirmation number assigned to the trade and be signed
by the shareholder exactly as the shares are registered. If the amount of the
redemption exceeds $50,000 or if the redemption proceeds will be sent to an
address other than the address of record, signature(s) must be guaranteed by a
member firm of a principal stock exchange, a commercial bank or trust company
which is a member of the Federal Deposit Insurance Corporation, a credit union
or a savings association. The guarantee must state the words "Signature
Guaranteed" along with the name of the granting institution. Shareholders should
verify with the institution that it is an eligible guarantor prior to signing. A
guarantee from a notary public is not acceptable. If certificates are held for
the shares being redeemed, such certificates must be sent endorsed for transfer
or accompanied by an endorsed stock power. Certificates should be sent by
registered mail to State Street Bank and Trust Company, c/o National Financial
Data Services, Van Kampen Merritt Funds, 1004 Baltimore Avenue, Dwight Building,
Sixth Floor, Kansas City, MO 64105-1807. Shareholders whose shares are held in
an Individual Retirement Account ("IRA") for which State Street Bank and Trust
Company acts as custodian may not sell their shares through their securities
dealers.
 
   
  REDEMPTION UPON DISABILITY. The Fund will waive the CDSC on Class B Share
redemptions following the disability of a Class B shareholder. An individual
will be considered disabled for this purpose if he or she meets the definitions
thereof in Section 72(m)(7) of the Internal Revenue Code (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 Fund will
require satisfactory proof of disability before it determines to waive the CDSC
on Class B Shares.
    
 
   
  In cases of disability, the CDSC on Class B 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
    
 
                                       31
<PAGE>   391
 
   
redemption is made within one year of the death or initial determination of
disability. This waiver of the CDSC on Class B 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. Whether shares are redeemed by the Fund or sold through a securities
dealer, a check for the proceeds (net of any required tax withholding and, with
respect to CDSC Shares, any applicable contingent deferred sales charge)
ordinarily will be mailed to shareholders or their dealer, as the case may be,
within seven calendar days after a redemption request or repurchase order and
share certificates (if any) are received in proper form as set forth above. Wire
transfers from the Fund of redemption proceeds, in the manner described above,
ordinarily will be transmitted to the shareholder within one business day. If
any shares are redeemed or repurchased shortly after purchase, the Fund will not
mail the proceeds until checks received for the purchase of shares have cleared,
which may take 10 days or more. The proceeds, of course, may be more or less
than the cost of the shares.
 
  The right of redemption or resale to the Fund may be suspended or the date of
payment postponed during any period when the New York Stock Exchange is closed
(other than customary weekend and holiday closings), when an emergency exists as
defined by rules and regulations of the SEC, or during any period when the SEC
has by order permitted such suspension or postponement.
 
  The Fund reserves the right to redeem any investment if the value of an
account falls below $500. Before the Fund makes such redemption it will provide
the shareholder with written notice and 30 days in which to make an additional
investment sufficient to increase the value of the account to at least $500.
 
- --------------------------------------------------------------------------------
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
 
                                       32
<PAGE>   392
 
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 sub-trust. 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.

- --------------------------------------------------------------------------------
THE 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 Investment
Company 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
 
                                       34
<PAGE>   394
 
Service Plan are being implemented through an 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, 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. Brokers, dealers and financial
intermediaries that have entered into Selling Agreements with the Distributor
and sell shares of the Fund are referred to herein as "financial
intermediaries."
 
  CLASS A SHARES. The Fund may spend an aggregate amount of up to 0.30% 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 provision of services to holders of such shares by the Distributor and
by financial intermediaries and in connection with the maintenance of
shareholders' accounts. The Fund pays the Distributor the lesser of the balance
of the 0.30% not paid to such 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 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 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
financial intermediary's customers. The Fund pays the Distributor the lesser of
the balance of 0.75% not paid to such 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 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.
 
                                       35
<PAGE>   395
 
   
  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 contingent deferred sales charge. 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
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. The Fund will disclose in its prospectus from
time to time the then current amount of any unreimbursed expenses with respect
to the CDSC Shares expressed as a dollar amount and as a percent of the Fund's
total net assets. As of December 31, 1994, there were $13,847 and $5,957 of
unreimbursed expenses with respect to Class B Shares and Class C Shares,
respectively, representing 0.04% and 0.02% of the Fund's total net assets. 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 contingent deferred sales charges.
    
 
  Because the Fund is a sub-trust of the Trust, amounts paid to the Distributor
as reimbursement for expenses of one sub-trust of the Trust may indirectly
benefit the other funds which are sub-trusts 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 contingent deferred sales charge
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.
 
- --------------------------------------------------------------------------------
TAX STATUS
- --------------------------------------------------------------------------------
 
The following federal income tax discussion is based on the advice of Skadden,
Arps, Slate, Meagher & Flom, and reflects applicable tax laws as of the date of
this Prospectus.
 
  TAXATION. The Fund intends to qualify each year and to elect to be treated as
a regulated investment company under Subchapter M of the Internal Revenue Code
of 1986, as amended (the "Code"). To qualify as a regulated investment company,
the Fund
 
                                       36
<PAGE>   396
 
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 and other
taxable income including net short-term capital gains, but not net capital
gains, which are the excess of net 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. As a sub-trust of a
Massachusetts business trust, the Fund will not be subject to any excise or
income taxes in Massachusetts as long as it qualifies as a regulated investment
company for federal income tax purposes.
 
  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 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 closed out), 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.
 
                                       37
<PAGE>   397
 
  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 certain 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.
 
  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 gross income be derived from the disposition of securities
held for less than three months.
 
  DISTRIBUTIONS. If the Fund qualifies as a regulated investment company and
satisfies the 90% distribution requirement, and if, at the close of each quarter
of the Fund's taxable year, at least 50% of the total value of the Fund's total
assets consist of obligations exempt from federal income tax ("tax-exempt
obligations"), the Fund will be qualified to pay exempt-interest dividends to
its Shareholders to the extent of its tax-exempt interest income (including
exempt interest dividends attributable to investments of the Fund in tax-exempt
money market funds) less expenses applicable thereto. Exempt-interest dividends
are treated by Shareholders as interest excludable from their gross income for
federal income tax purposes but 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. Such dividends may be
taxable for state and local purposes. Interest with respect to indebtedness
incurred or continued by a Shareholder to purchase or carry shares of the Fund
is not deductible to the extent that such interest relates to exempt-interest
dividends received from the Fund.
 
  Distributions of the Fund's investment company taxable income (which does not
include tax-exempt interest income) are taxable to Shareholders as ordinary
income 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 at the rates applicable to long-term capital gains regardless of
the length of time Shares of the Fund have been held by such Shareholders.
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). It is not expected that any portion of the
distributions from the Fund will be eligible for the dividends received
deduction for corporations. The Fund will inform Shareholders of the source and
tax status of all distributions promptly after the close of each calendar year.
 
  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
 
                                       38
<PAGE>   398
 
date. The basis of such Shares will equal the fair market value on the
distribution date. Shareholders receiving distributions in the form of
additional Shares purchased by the Plan Agent under the Fund's Dividend
Reinvestment Plan will be treated for federal income tax purposes as receiving
the amount of cash received by the Plan Agent on their behalf. In general, the
basis of such Shares will equal the price paid by the Plan Agent for such
Shares.
 
  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 a 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.
 
  Exempt-interest dividends allocable to interest received by the Fund on
certain "private activity" obligations issued after August 7, 1986 will be
treated as interest on such obligations and thus will give rise to an item of
tax preference that will increase a Shareholder's alternative minimum taxable
income. In addition, for corporations, alternative minimum taxable income will
be increased by a percentage of the amount by which a measure of income that
includes interest on all tax-exempt obligations exceeds the amount otherwise
determined to be the alternative minimum taxable income. Accordingly, investment
in the Fund may cause Shareholders to be subject to (or result in an increased
liability under) the alternative minimum tax.
 
  Exempt-interest dividends will not be tax-exempt to the extent made to any
Shareholder who is a "substantial user" of the facilities financed by tax-exempt
obligations held by the Fund or "related persons" of such substantial users.
 
  The Fund is required, in certain circumstances, to withhold 31% of taxable
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 disallowed to the
extent of any exempt-interest dividends received with respect to such Shares. If
such loss is not entirely disallowed, it will be treated as a long-term capital
loss to the extent of any capital gains dividends received with respect to such
Shares.

  GENERAL. The federal 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 laws and any proposed tax
law changes.
 
- --------------------------------------------------------------------------------
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,
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.
 
- --------------------------------------------------------------------------------
SHAREHOLDER PROGRAMS
- --------------------------------------------------------------------------------
 
   
  SHARE CERTIFICATES.  As a rule, the Fund will not issue share certificates.
Upon written or telephone request to the Fund, however, 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. In addition, if such certificates are lost the shareholder must
write to State Street Bank and Trust Company, c/o National
    
 
                                       40
<PAGE>   400
 
Financial Data Services, P.O. Box 419001, Kansas City, MO 64141-6001, Attn: Van
Kampen Merritt Funds, requesting an "affidavit of loss" and to obtain a Surety
Bond in a form acceptable to the Transfer Agent. On the date the letter is
received the Transfer Agent will calculate no more than 2.00% of the net asset
value of the issued shares, and bill the party to whom the certificate was
mailed.
 
   
  SYSTEMATIC WITHDRAWAL PROGRAM.  If a shareholder's Class A Shares account or
Class B Shares account is valued at $10,000 or more, and such shareholder's
dividends are being reinvested, a requested dollar amount may be paid from such
account to any person monthly, quarterly, semiannually or annually. The minimum
amount that may be withdrawn each period is $50; withdrawals will be made on the
seventh business day of the month in which they are scheduled to occur.
Depending upon the size of the payments requested and the fluctuations in the
net asset value of the shares redeemed, redemptions for the purpose of making
such payments may reduce or even exhaust the amounts in such account. If an
investor acquires additional shares of the Fund after joining the Systematic
Withdrawal Program, the investor must inform the Fund if he or she wants the new
shares to be subject to the Systematic Withdrawal Program by telephoning the
Fund at 1-800-341-2911.
    
 
   
  With respect to redemptions of Class B Shares made pursuant to the Systematic
Withdrawal Program, an investor may annually redeem up to 12% of the net asset
value of the investor's initial investment in Class B Shares or, if the investor
does not join the program on the date of his or her initial investment, the net
asset value of the investor's Class B Shares on the date the investor elects to
participate in the Systematic Withdrawal Program. The Fund will waive the
contingent deferred sales charge applicable to Class B Shares redeemed pursuant
to the Fund's Systematic Withdrawal Program.
    
 
  It will ordinarily be disadvantageous to purchase shares (except through
reinvestment of distributions) while participating in a systematic withdrawal
program because a shareholder will be paying a sales charge, or will become
subject to a contingent deferred sales charge, in order to purchase shares at
the same time that shares are being redeemed upon which a sales charge may
already have been paid. Therefore, the Fund will not knowingly permit a
shareholder to make additional investments in shares of less than $5,000 if at
the same time such shareholder is making systematic withdrawals at a rate
greater than the distribution being paid on such shareholder's shares. The Fund
reserves the right to amend or terminate the systematic withdrawal program on
thirty days' notice, and a shareholder may withdraw from the program at any
time.
 
  EXCHANGE PRIVILEGE.  Any Class A Shares of the Fund which have been registered
in a shareholder's name for at least 15 days may be exchanged for ISC Shares of
any other Van Kampen Merritt mutual fund distributed by the Distributor that
offer an exchange privilege. Under the exchange privilege, the Fund offers to
exchange its Class A Shares for ISC Shares on the basis of relative net asset
value per share. Any ISC Shares exchanged into the Fund that have been charged a
sales load lower than the sales load applicable to Class A Shares of the Fund
will be charged the applicable sales load differential upon exchange. ISC Shares
of the Van Kampen Merritt Money Market Fund and Van Kampen Merritt Tax Free
Money Fund which have not previously been charged a sales load
 
                                       41
<PAGE>   401
 
(except for shares purchased via the reinvestment option) will be charged the
applicable sales load upon exchange into the Fund.
 
  Class B Shareholders of the Fund may exchange their Class B Shares
("Outstanding Class B Shares") for Class B Shares of other Van Kampen Merritt
mutual funds sponsored by the Distributor ("New Class B Shares") on the basis of
relative net asset value per Class B Share, without the payment of any
contingent deferred sales charge that might otherwise be due on redemption of
the Outstanding Class B Shares. Class B Shares of a fund acquired through use of
the exchange privilege will be 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.
 
   
  Class C Shares of the Fund are exchangeable for Class C Shares of other Van
Kampen Merritt mutual funds distributed by the Distributor on the same terms set
forth in the preceding paragraph with respect to Class B Shares, except that
Class C Shares do not convert to Class A Shares. The exchange privilege with
respect to any Van Kampen Merritt money market fund sponsored by the Distributor
is not available for Class C Shareholders.
    
 
   
  In order to qualify for the exchange privilege, it is required that the Class
A Shares being exchanged have a net asset value of at least $1,000 (unless prior
approval has been obtained from the Fund). Class A Shareholders will be able to
effect an exchange by telephone by calling the Fund at 1-800-341-2911 prior to
3:00 p.m. Central Standard Time and requesting the exchange. For inquiries
through Telecommunications Device for the Deaf (TDD), dial 1-800-772-8889,
during the hours of 7:30 a.m. to 3:00 p.m. Central Standard Time. The exchange
will be processed at the net asset value next determined after receipt of such
request. By utilizing the telephone exchange service, a shareholder authorizes
the Fund or the Transfer Agent to act upon the instructions of any person by
telephone to exchange shares from any account for which such service has been
authorized to any identically registered account(s) with any Van Kampen Merritt
fund distributed by the Distributor that offers an exchange privilege. The Fund,
the Distributor, the Transfer Agent and NFDS seek to employ procedures
reasonably believed to confirm that instructions communicated by telephone are
genuine. Such procedures include requiring an investor attempting to exchange
shares by telephone to provide, on a recorded line, the name of the account, a
social security or tax identification number and such additional information as
may be deemed necessary or appropriate. An investor agrees that no such person
will be liable for any loss, liability, cost or expense arising out of any
request reasonably believed to be genuine, including any fraudulent or
unauthorized request. This service may be amended or terminated at any time by
the Transfer Agent or the Fund. If a shareholder has certificates for any Class
A Shares being exchanged, such certificates must be surrendered prior to the
exchange in the same manner as in redemption of such shares. See "Redemption of
Shares--Telephone Redemptions." Any Class A Shares exchanged between the Fund
and any of the other funds will begin earning dividends on the next business day
after the exchange is effected. 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.
    
 
                                       42
<PAGE>   402
 
  An exchange between Van Kampen Merritt funds pursuant to the exchange
privilege is treated as a sale for federal income tax purposes and, depending
upon the circumstances, a short- or long-term capital gain or loss may be
realized.
 
  The exchange privilege may be modified or terminated at any time, subject to
the requirement that the Fund give prominent notice thereof at least 60 days
prior to the effective date of the modification or termination in certain
circumstances. The Fund reserves the right to limit the number of times a
shareholder may exercise the exchange privilege.
 
  AUTOMATED MULTIPLE ACCOUNT SHAREHOLDER SERVICES (AMASS(SM)).
 
   
  1. 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
the Transfer Agent 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 the Transfer
Agent.
    
 
  2. Automated Dividend Programs.  The Fund will, upon the election of a
shareholder, automatically invest distributions from a shareholder's account
directly into a shareholder's bank account.
 
   
  3. Dividend Diversification.  Monthly distributions and any net long-term
capital gain distributions to a shareholder's account may be invested in the
same class of shares of any other Van Kampen Merritt mutual fund distributed by
the Distributor at the then current net asset value, WITHOUT A SALES CHARGE,
upon election by a shareholder. This election may be made on the account
application bound in this Prospectus, by written notice to the Transfer Agent or
by calling the Fund directly at 1-800-341-2911, during the hours of 7:00 a.m. to
7:00 p.m. Central Standard Time. For inquiries through Telecommunications Device
for the Deaf (TDD), dial 1-800-772-8889. In order to qualify for this privilege,
a shareholder must have established an account in the other mutual fund prior to
electing this privilege. This privilege may be modified or terminated by the
Fund at any time.
    
 
  4. Easy Account Savings Enhancement Plan (EASESM).  Once a shareholder has
opened an account with the minimum $1,000 investment, the automatic investment
option may be utilized to make regular electronic monthly investments of $100 or
more into such shareholder's account with the Fund. In order to utilize this
option, a shareholder must fill out and sign the appropriate section of the
application attached to this Prospectus or the EASESM application which is
available from the Transfer Agent, the Fund, such shareholder's broker or dealer
or the Distributor. Once the Transfer Agent has received
 
                                       43
<PAGE>   403
 
this application, such shareholder's checking account at his or her designated
local bank will be debited each month in the amount authorized by such
shareholder to purchase shares of the Fund. Once enrolled in the EASESM program,
a shareholder may change the monthly amount or terminate participation at any
time by writing or calling the Transfer Agent. Shareholders in the EASESM
program will receive a confirmation of these transactions from the Fund monthly,
and their regular bank account statements will show the debit transaction each
month.
 
  By electing to utilize any of the foregoing services, a shareholder authorizes
the Transfer Agent or its agent to act upon the instructions indicated in the
appropriate section of the Application in performing such services by either
withdrawing funds for deposit in the Fund pursuant to the EASESM Plan or
depositing distributions and redemptions in the bank account indicated by the
voided check or deposit slip accompanying the shareholder's election and/or by
depositing the shareholder's distributions in the Van Kampen Merritt fund
account indicated. A shareholder also agrees that neither the Fund, the
Distributor, the Transfer Agent nor NFDS will be liable for any loss, liability,
cost or expense arising out of any request, including any fraudulent request.
This service may be amended or terminated at any time by the Transfer Agent or
by the Fund.
 
  REINSTATEMENT PRIVILEGE. A shareholder who has redeemed Class A Shares or
Class B Shares may, within 120 days, repurchase Class A Shares of the Fund, or
shares of other Van Kampen Merritt mutual funds distributed by the Distributor,
in an amount of at least $500 and not exceeding the redemption proceeds
received, at a purchase price equal to the net asset value next determined after
the reinstatement request is received by the Transfer Agent or the Distributor.
A Class C Shareholder who has redeemed shares of the Fund may repurchase Class C
Shares of the Fund, or shares of other Van Kampen Merritt mutual funds
distributed by the Distributor with credit given for any contingent deferred
sales charge paid upon such redemption.
 
  Exercising the reinstatement privilege will not affect the character of any
gain or loss realized on the redemption for federal income tax purposes, except
that if the redemption resulted in a loss, the reinstatement may result in the
loss being disallowed under the "wash sale" rules.
 
- --------------------------------------------------------------------------------
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
Class A Shares and Class B 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., Business Week, Forbes or other industry publications. From time
to time, the Fund may
 
                                       44
<PAGE>   404
 
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 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 Class
A Shares and Class B Shares.
 
  Please consult the Statement of Additional Information for more information
regarding the Fund's performance.
 
- --------------------------------------------------------------------------------
DESCRIPTION OF SHARES OF THE FUND
- --------------------------------------------------------------------------------
 
  The Fund is a sub-trust of the Van Kampen Merritt Tax Free Fund, a
Massachusetts business trust organized August 15, 1985 (the "Trust"). Shares of
the Trust entitle their holders to one vote per share; however, separate votes
are taken by each sub-trust on matters affecting an individual sub-trust.
 
  The authorized capitalization of the Fund consists of an unlimited number of
shares of beneficial interest, without 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 "The
Distribution and Service Plans."
 
  Pursuant to an order of the SEC, 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 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 Class B Shareholders and Class C Shares are likely to be
lower than to Class A Shareholders.
 
                                       45
<PAGE>   405
 
  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 a majority of the shares present and voting at
such meeting. The Trust will assist such holders in communicating with other
shareholders of the Fund to the extent required by the Investment Company Act.
More detailed information concerning the Trust is set forth in the Statement of
Additional Information.

Shareholders will receive monthly statements giving details of all activity in
their account(s) and will also receive a statement whenever an investment or
withdrawal is made in or from their account. Information for federal income tax
purposes will be provided at the end of the year. Such statements will present
separately information with respect to each class of the Fund's shares. It is
expected that the transfer agency costs attributable to the Class B Shares and
Class C Shares will be higher than the transfer agency costs attributable to the
Class A Shares.
 
  The fiscal year of the Fund ends on December 31. The Fund sends to its
shareholders at least semi-annually reports showing the Fund's portfolio and
other information. An annual report, containing financial statements audited by

year, shareholders will receive federal income tax information regarding
dividends and capital gains distributions.

                      STATEMENT OF ADDITIONAL INFORMATION
 
             VAN KAMPEN MERRITT LIMITED TERM MUNICIPAL INCOME FUND
 
     The Van Kampen Merritt Limited Term Municipal Income Fund (the "Fund")
seeks to provide high current income exempt from federal income taxes consistent
with preservation of capital. The Fund attempts 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. There is no assurance that the Fund will achieve its investment
objective. The Fund is a separate sub-trust of Van Kampen Merritt Tax Free Fund,
a Massachusetts business trust (the "Trust").

                             THE FUND AND THE TRUST
 
   
  The Fund is a separate sub-trust of the Trust, an open-end diversified
management investment company. At present, the Fund, Van Kampen Merritt
Municipal Income Fund, Van Kampen Merritt Insured Tax Free Income Fund, Van
Kampen Merritt Tax Free High Income Fund, Van Kampen Merritt California Insured
Tax Free Fund, Van Kampen Merritt Florida Insured Tax Free Income Fund, Van
Kampen Merritt New Jersey Tax Free Income Fund and Van Kampen Merritt New York
Tax Free Income Fund have been organized as sub-trusts of the Trust and have
commenced investment operations. Van Kampen Merritt California Tax Free Income
Fund, Van Kampen Merritt Michigan Tax Free Income Fund, Van Kampen Merritt
Missouri Tax Free Income Fund and Van Kampen Merritt Ohio Tax Free Income Fund
have been organized as sub-trusts of the Trust but have not commenced investment
operations. Other sub-trusts may be organized and offered in the future.
    
 
  The Trust is an unincorporated business trust established under the laws of
the Commonwealth of Massachusetts by a Declaration of Trust dated August 15,
1985. The Declaration of Trust permits the Trustees to issue an unlimited number
of full and fractional shares in separate sub-trusts. Each share represents an
equal proportionate interest in the assets of the sub-trust with each other
share in such sub-trust and no interest in any other sub-trust. No sub-trust is
subject to the liabilities of any other sub-trust. The Declaration of Trust
provides that shareholders are not liable for any liabilities of the Trust or
any of its sub-trusts, requires inclusion of a clause to that effect in every
agreement entered into by the Trust or any of its sub-trusts 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 sub-trust on matters affecting an individual
sub-trust. For example, a change in investment policy for a sub-trust would be
voted upon by shareholders of only the sub-trust involved. 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 a majority of the shares present and voting at
such meeting.
 
  The Trustees may amend the Declaration of Trust (including with respect to any
sub-trust) in any manner without shareholder approval, except that the Trustees
may not adopt any amendment adversely affecting the rights of shareholders of
any sub-trust without approval by a majority of the shares of each affected
sub-trust present at a meeting of shareholders (or such higher vote as may be
required by 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 (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.
 
   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
 
                                       B-2
<PAGE>   409
 
      securities market; however, the Fund will not invest more than 25% of its
      assets in industrial development bonds in a single industry.
 
   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
      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 municipal securities would be deemed to
      constitute such control or participation.
 
   9. Invest in securities of other investment companies, except as part of a
      merger, consolidation or other acquisition and except that the Fund may
      invest up to 10% of its assets in tax-exempt investment companies that
      invest in securities rated comparably to those the Fund may invest in so
      long as the Fund does not own more than 3% of the outstanding voting stock
      of any tax-exempt investment company or securities of any tax-exempt
      investment company aggregating in value more than 5% of the total assets
      of the Fund.
 
  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.
 
  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 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 outstanding 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
 
                                       B-3
<PAGE>   410
 
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 10 and 15 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" 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
 
                                       B-4
<PAGE>   411
 
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 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>   412
 
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, 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 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. 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
 
                                       B-6
<PAGE>   413
 
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.
 
                                       B-7
<PAGE>   414
 
  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 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
 
                                       B-8
<PAGE>   415
 
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 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
 
                                       B-9
<PAGE>   416
 
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 Investment Company Act of 1940 ("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 high-grade securities
at least equal to the current amount of the obligation must be segregated with
the custodian. The segregated assets cannot be sold or
 
                                      B-10
<PAGE>   417
 
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 high-grade 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, high-grade
assets 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 high-grade 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 Internal Revenue 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 Standard & Poor's 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.
    
 
                                      B-11
<PAGE>   418
 
          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 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 balance, as
    B         predominantly speculative with respect to capacity to pay interest and repay
    CCC       principal. 'BB' indicates the least degree of speculation and 'C' the highest.
    CC        While such debt will likely have some quality and protective characteristics,
    C         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.

<PAGE>   419
 
   
<TABLE>
    <S>       <C>
    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
              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 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 completion of
              construction or elimination of basis of condition.
 
    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 senior debt obligations which have an original maturity
     not exceeding one year. 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 (or supporting institutions) have a superior
        ability for repayment of senior short-term debt obligations.
 
             Issuers rated Prime-2 (or supporting institutions) have a strong
        ability for repayment of senior short-term debt obligations.
 
             Issuers rated Prime-3 (or supporting institutions) have an
        acceptable ability for repayment of senior short-term debt obligations.
 
          Issuers rated Not Prime do not fall within any of the Prime rating
     categories.

* Interested persons of each respective Fund as defined in the 1940 Act.

  The compensation of the officers and trustees who are affiliated persons (as
defined in the 1940 Act) of the Adviser, Van Kampen American Capital
Distributors, Inc. or Van Kampen American Capital, Inc. is paid by the
respective entity. The Fund pays the compensation of all other officers and
trustees of the Fund. During the next year, the Fund expects to pay trustees who
are not affiliated persons of the Adviser, Van Kampen American Capital
Distributors, Inc. or Van Kampen American Capital, Inc. $2,500 per year, and
$250 per meeting of the Board of Trustees, plus expenses. Under the Fund's
retirement plan, trustees who are not affiliated with the Adviser, Van Kampen
American Capital Distributors, Inc. or Van Kampen American Capital, Inc., have
at least ten years of service and retire at or after attaining the age of 62,
are eligible to receive a retirement benefit equal to the annual retainer for
each of the ten years following such trustee's retirement. Under certain
conditions, reduced benefits are available for early retirement. Under the
Fund's deferred compensation plan, a trustee who is not affiliated with the
Adviser, Van Kampen American Capital Distributors, Inc. or Van Kampen American
Capital, Inc. can elect to defer receipt of all or a portion of the trustee's
fees earned by such trustee until such trustee's retirement. The deferred
compensation earns a rate of return determined by reference to the Fund or other
Van Kampen Merritt mutual funds advised by the Adviser as selected by the
trustee. To the extent permitted by the Investment Company Act, the Fund may
invest in securities of other Van Kampen Merritt mutual funds advised by the
Adviser 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.

(1)     Messrs. Merritt and McDonnell, Trustees of each Fund during fiscal year
      1994, are affiliated persons of the Adviser and are not eligible for
      compensation or retirement benefits from the Funds.
    
 
   
(2)     The Registrant is Van Kampen Merritt Tax Free Fund (the "Trust") which
      currently is comprised of 8 sub-trusts, including the Fund. The amounts
      shown in this column are accumulated from the Aggregate Compensation of
      each of these 8 sub-trusts during such sub-trust's last completed fiscal
      year prior to the date of this Statement of Additional Information.
      Beginning in October 1994 each Trustee, except Messrs. Gaughan and Whalen,
      began deferring his entire aggregate compensation paid by the Fund. The
      total combined amount of deferred compensation (including interest)
      accrued with respect to each Trustee as of December 31, 1994 is as
      follows: Mr. Kennedy, $14,737; Mr. Miller, $14,553; Mr. Nelson, $14,737
      and Mr. Robinson, $13,725.
    
 
   
(3)     The Retirement Plan commenced as of August 1, 1994 for the Fund. As of
      the end of the Fund's 1994 fiscal year, no amounts had been accrued for
      retirement benefits because such amounts were either zero or considered to
      be immaterial to the net assets of the Fund at such time. During the
      Fund's 1995 fiscal year, the Fund will accrue amounts for retirement
      benefits and include an amount, if any, for such Fund's 1994 fiscal year.
    
 
   
(4)     This is the estimated annual benefits payable per year for the 10-year
      period commencing in the year of such Trustee's retirement by a Fund
      assuming: the Trustee has 10 or more years of service on the Board of the
      Fund, retires at or after attaining the age of 60 and the annual retainer
      in the year prior to the Trustee's retirement is $2,500. Trustees retiring
      prior to the age of 60 or with fewer than 10 years of service for the Fund
      may receive reduced retirement benefits from such Fund.

(5)   The Fund Complex consists of 20 mutual funds advised by the Adviser. The
      amounts shown in this column are accumulated from the Aggregate
      Compensation of each of these 20 mutual funds in the Fund Complex during
      each fund's last completed fiscal year prior to the date of this Statement
      of Additional Information. The Adviser also serves as investment adviser
      for other mutual funds and closed-end investment companies; however, with
      the exception of Messrs. McDonnell and Whalen, such mutual funds and
      closed-end investment companies do not have the same trustees as the Fund
      Complex. Combining the Fund Complex with other mutual funds and investment
      companies advised by the Adviser, Mr. Whalen received Total Compensation
      of $161,850.
    
 
   
  As of April 13, 1995, the trustees and officers as a group own less than 1% of
the shares of the Fund.
    
 
   
  No officer or trustee of the Fund owns or would be able to acquire 5% or more
of the common stock of VK/AC Holding, Inc.
    
 
   
  The authorized stock of the Fund currently consists of an unlimited number of
full and fractional shares of beneficial interest, without par value.

Presently, and after giving effect to the exercise of stock options, no officer
or trustee of the Fund owns or would own 5% or more of the common stock of VK/AC
Holding, Inc.
 
  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.
 
                                      B-20
<PAGE>   427
 
  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 sub-trust, to whom the
Adviser renders periodic reports of the Fund's investment activities.
 
  The investment advisory agreement for the Fund will be submitted for approval
by the shareholders of the Fund at the first meeting of shareholders held after
commencement of operations. 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 sub-trust (or by the Fund's
shareholders), and by the disinterested trustees in compliance with the
requirements of the Investment Company Act of 1940. 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 ending December 31, 1994 and the period ended December 31, 1993,
the Fund recognized advisory expenses of $0 and $0, respectively.
    
 
OTHER AGREEMENTS
 
  SUPPORT SERVICES AGREEMENT.  Under a support services agreement with the
Distributor the Fund receives support services for shareholders, including the
handling of all written and telephonic communications, except initial order
entry and other distribution related communications. Upon entering into such
agreement, the Fund realized a reduction in the fee which would have been paid
to the Transfer Agent if the Transfer Agent had provided such services. Payment
by the Fund for such services is made on cost basis for the employment of the
personnel and the equipment necessary to render the support services. The Fund,
and the other Van Kampen Merritt mutual funds distributed by the Distributor,
share such costs proportionately among themselves based upon their respective
net asset values.
 
   
  For the year ending December 31, 1994 and the period ended December 31, 1993,
the Fund recognized expenses of approximately $16,475 and $3,270, respectively,
representing the Distributor's cost of providing certain support services.
    
 
   
  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, together with the other Van Kampen Merritt mutual funds
distributed by Van Kampen American Capital Distributors, Inc., in 25% of the
cost of providing such services, with the remaining 75% of such cost being paid
by the Fund and such other Van Kampen Merritt funds based proportionally on
their respective net assets.
    
 
   
  For the year ending December 31, 1994 and the period ended December 31, 1993,
the Fund recognized expenses of approximately $4,055 and $1,526, respectively,
representing the Adviser's cost of providing accounting services.
    
 
                                      B-21
<PAGE>   428
 
  LEGAL SERVICES AGREEMENT.  The Fund has entered into a Legal Services
Agreement pursuant to which Van Kampen American Capital, Inc. provides legal
services, including without limitation: 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 Fund. 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. The Fund,
and the other Van Kampen Merritt mutual funds distributed by the Distributor,
share one half (50%) of such costs equally. The remaining one half (50%) of such
costs are allocated to specific funds based on specific time allocations, or in
the event services are attributable only to types of funds (i.e. closed-end or
open-end), the relative amount of time spent on each type of fund and then
further allocated between funds of that type based upon their respective net
asset values.
 
   
  For the year ending December 31, 1994 and the period ended December 31, 1993,
the Fund recognized expenses of approximately $8,086 and $4,800, respectively,
representing Van Kampen American Capital, Inc.'s cost of providing legal
services.
    
 
                       CUSTODIAN AND INDEPENDENT AUDITORS
 
  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 auditors for the Fund are KPMG Peat Marwick LLP, Chicago,
Illinois. The selection of independent auditors 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 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
    
 
                                      B-22
<PAGE>   429
 
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 sub-trust.
 
   
  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 each of its sub-trusts, including the Fund, will be treated as
separate corporations for income tax purposes. The Fund will be subject to tax
if, among other things, it fails to distribute net capital gains, or if its
annual distributions, as a percentage of its income, are less than the
distributions required by tax laws.
 
                                THE DISTRIBUTOR
 
  Shares of the Fund are offered through the Distributor, One Parkview Plaza,
Oakbrook Terrace, IL 60181. The Distributor is a wholly owned subsidiary of Van
Kampen American Capital, Inc., which is a subsidiary of VK/AC Holding, Inc., a
Delaware corporation that is controlled through an ownership of a substantial
majority of its common stock, by The Clayton & Dubilier Private Equity Fund IV
Limited Partnership ("C & D L.P."), a Connecticut limited partnership. In
addition, certain officers, directors and employees of Van Kampen American
Capital, Inc., and its subsidiaries own, in the aggregate not more than 6% of
the common stock of VK/AC Holding, Inc. and have the right to acquire, upon the
exercise of options, approximately an additional 10% of the common stock of
VK/AC Holding, Inc. C & D L.P. is managed by Clayton, Dubilier & Rice, Inc.
Clayton & Dubilier Associates IV Limited Partnership ("C & D Associates L.P.")
is the general partner of C & D L.P. 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.
 
  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 banks 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
 
                                      B-23
<PAGE>   430
 
and banks 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 and/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 sub-trust, 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 year ended December 31, 1994, the Fund has recognized expenses under
the Plans of $46,785, $174,932 and $28,679 for the Class A Shares, Class B
Shares and Class C Shares, respectively, of which $38,320, $35,205 and $2,052
represent payments to financial intermediaries under the Selling Agreements for
Class A Shares, Class B Shares and Class C Shares, respectively. For the year
ended December 31, 1994, the Fund has reimbursed the Distributor $4,083 and
$3,862 for advertising expenses, and $1,630 and $4,652 for compensation of the
Distributor's sales personnel for the Class A Shares and Class B Shares,
respectively.
    
 
                                 LEGAL COUNSEL
 
  Counsel to the Fund is Skadden, Arps, Slate, Meagher & Flom, Chicago,
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
 
                                      B-24
<PAGE>   431
 
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 Shares imposed at the time of redemption were reflected, it would
reduce the performance quoted.

Independent Auditors' Report


The Board of Trustees and Shareholders of
Van Kampen Merritt Limited Term Municipal Income Fund:


We have audited the accompanying statement of assets and liabilities of
Van Kampen Merritt Limited Term Municipal Income Fund (the "Fund"),
including the portfolio of investments, as of December 31, 1994, and the
related statement of operations for the year then ended, and the statement
of changes in net assets and the financial highlights for the year then
ended and for the period from October 19, 1993 (commencement of
investment operations) through December 31, 1993. 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, 1994, 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 Merritt Limited Term Municipal Income Fund 
as of December 31, 1994, the results of its operations for the year then ended,
and the changes in its net assets and financial highlights for the year then
ended and for the period from October 19, 1993 (commencement of investment
operations) through December 31, 1993, in conformity with generally accepted
accounting principles.

Van Kampen Merritt Limited Term Municipal Income Fund
- --------------------------------------------------------------------------------

Notes to Financial Statements
December 31, 1994
- --------------------------------------------------------------------------------

1. Significant Accounting Policies
Van Kampen Merritt Limited Term Municipal Income Fund (the "Fund")
was organized as a sub-trust of Van Kampen Merritt Tax Free Fund (the
"Trust"), a Massachusetts business trust, as of February 12, 1993, and is
registered as a diversified open-end management investment company
under the Investment Company Act of 1940, as amended. 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, which were initially introduced as Class D shares
and subsequently renamed Class C shares on March 7, 1994, 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.


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 less
than 60 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" and "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 and Initial Registration Costs-The Fund has
reimbursed Van Kampen American Capital Distributors, Inc. or its affiliates
("VKAC") for costs incurred in connection with the Fund's organization and
initial registration 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 and initial
registration costs 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, 1994, the Fund had an accumulated capital loss carryforward of
$849,643 which will expire on December 31, 2002. Net realized gains or losses
may differ for financial and tax reporting purposes primarily as a result of
post October 31 losses which are not recognized for tax purposes until the first
day of the following fiscal 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. Distributions from net realized gains for book purposes
may include short-term capital gains, which are included in ordinary income for
tax purposes.

2. Investment Advisory Agreement and Other Transactions with Affiliates
Under the terms of the Fund's Investment Advisory Agreement, the Adviser will 
provide facilities and investment advice to the Fund for an annual fee payable
monthly as follows:

First $500 million...  .500 of 1% 
Over $500 million....  .450 of 1%       

</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, 1994 the Fund recognized expenses of 
approximately $28,600, representing VKAC's cost of providing accounting, legal
and certain shareholder services to the Fund.

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, 1994, VKAC owned 1,000, 100 and 100 shares of beneficial 
interest of Classes A, B and C, respectively.


3. Capital Transactions
The Fund has outstanding three classes of common shares, Classes A, B and C. 
There are an unlimited number of shares of each class without par value 
authorized.

At December 31, 1994, paid in surplus aggregated $16,686,522, $18,859,775 and
$4,882,157 for Classes A, B and C, respectively. For the year ended December 31,

Class B and C shares are offered without a front end sales charge,

for Class B and Class C shares will be imposed on most redemptions
made within four years of the purchase for Class B and one year of the
purchase for Class C as detailed in the following schedule. The Class B
and Class C shares bear the expense of their respective deferred sales
arrangements, including higher distribution and service fees and incre
mental transfer agency costs.

                               PROSPECTUS SUMMARY
- --------------------------------------------------------------------------------
 
  The following summary is qualified in its entirety by reference to the more
detailed information included elsewhere in this Prospectus and the Statement of
Additional Information.
 
THE FUND  Van Kampen Merritt Florida Insured Tax Free Income Fund (the "Fund")
is a non-diversified mutual fund, organized as a separate sub-trust of Van
Kampen Merritt Tax Free Fund.
 
INVESTMENT OBJECTIVE AND POLICIES  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. 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."
 
PURCHASING SHARES OF THE FUND  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 with respect to each class
is $1,000. 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 "Purchasing Shares of the Fund."
 
   
INVESTMENT ADVISER  Van Kampen American Capital Investment Advisory Corp. (the
"Adviser") is the investment adviser for the Fund. See "Investment Advisory
Services."
    
 
                                        4
<PAGE>   447
 
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 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 "Investment Advisory
Services" and "The Distribution and Service Plans."

THE FUND
- --------------------------------------------------------------------------------
 
  Van Kampen Merritt Florida Insured Tax Free Income Fund (the "Fund") is a
non-diversified, separate sub-trust of Van Kampen Merritt Tax Free Fund (the
"Trust"), an open-end management investment company, commonly known as a "mutual
fund," organized as a Massachusetts 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 "Investment Company 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.
 
  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
 
                                       10
<PAGE>   453
 
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 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 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
 
                                       12
<PAGE>   455
 
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 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
 
                                       13
<PAGE>   456
 
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 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
 
                                       14
<PAGE>   457
 
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.
 
  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."
 
                                       15
<PAGE>   458
 
   
  "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 high-grade municipal portfolio 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 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
 
                                       16
<PAGE>   459
 
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 Investment Company Act. See
"Investment Policies and Restrictions" in the Statement of Additional
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 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
 
                                       17
<PAGE>   460
 
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; however, unemployment levels during the past several years
have been above the national level and are estimated to continue to be above the
national level for the State's 1993-94 fiscal year which ends June 30, 1994.
Since 1980, Florida's unemployment rate has generally tracked below that of the
nation; however, since 1989 the State's jobless rate has moved ahead of the
national average. The average rate of unemployment for Florida since 1980 is
6.5% while the national average during the same time period is 7.1%. Florida's
unemployment rate is forecasted at 6.5% for fiscal year 1994-95 and fiscal year
1995-96.
    
 
  For the State fiscal year which ended June 30, 1994, receipts from the sales
and use tax, the greatest single source of tax revenue to the State of Florida,
were $10,012.5 million, an increase of 6.9% from fiscal year 1992-93.
 
   
  Zero growth in the number of tourists in the State of Florida is expected over
the current fiscal year due in part to negative publicity regarding crime
against tourists.
    
 
  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.
 
  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.

PURCHASING SHARES OF THE FUND
- --------------------------------------------------------------------------------
 
  The Fund currently offers three classes of shares to the public through Van
Kampen American Capital Distributors, Inc., (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 or eligible non-NASD members acting as brokers or agents
for investors ("brokers"). The Fund reserves the right to suspend or terminate
the public offering of its shares at any time and without prior notice.
 
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 fees with respect to each class of shares that may be incurred over
the anticipated duration of their investment in the Fund.
 
   
  The Fund currently 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
$1,000,000 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 $1,000.
The minimum subsequent investment with respect to each class of shares is $100.
It is presently the policy of the Distributor, not to accept any order for Class
B Shares or Class C Shares in an amount of $1,000,000 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
 
                                       19
<PAGE>   462
 
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). Investors who intend to hold their shares for a
significantly long time may not wish to continue to bear the ongoing
distribution and service expenses of Class C Shares which, in the aggregate,
eventually would exceed the aggregate amount of the initial sales charge and
distribution and service related expenses applicable to Class A Shares,
irrespective of the fact that a CDSC would eventually not apply to a redemption
of such Class C shares.
 
  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. Only the Class B Shares are subject to
a conversion feature (discussed below). Generally, a class of shares subject to
a higher ongoing distribution fee, service fee or, where applicable, the
conversion feature will have a higher expense ratio and pay lower dividends than
a class of shares subject to a lower ongoing distribution fee 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 "Net Asset Value."
 
  The administrative expenses that may be allocated to a specific class of
shares may consist of (i) transfer agency 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 that shall be approved by the SEC pursuant to
an amended exemptive order. 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
 
                                       20
<PAGE>   463
 
the extent necessary to preserve the Fund's qualification as a regulated
investment company under the Internal Revenue Code of 1986, as amended.
 
  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
securities 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. See "Net Asset
Value."
 
   
  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 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. 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. In addition, the Distributor may, from time to
time, sponsor sales contests with respect to sales of the Fund's Class A Shares
and Class B Shares pursuant to which brokers, dealers and financial
intermediaries may receive additional compensation of up to 2% of sales in such
shares. In connection therewith, the Distributor may combine the sales of shares
made by brokers, dealers and financial intermediaries of certain funds in The
Van Kampen Merritt Family of Funds. In addition, 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. In addition, the Distributor is sponsoring a sales contest for
INVEST Financial Corporation ("INVEST") relating to the Fund and other funds
distributed by the Distributor, pursuant to which the Distributor may provide an
INVEST broker an award valued up to $750.00 for sales of such funds
    
 
                                       21
<PAGE>   464
 
   
during the period April 1, 1995, through May 31, 1995. Such payments are made by
the Distributor out of its own assets, and not out of the assets of the Fund.
These programs will not change the price an investor pays for shares or the
amount that the Fund will receive from such sale.
    
 
INITIAL SALES CHARGE ALTERNATIVE--CLASS A SHARES
 
  The public offering price of Class A Shares for purchasers choosing the
initial sales charge alternative 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 an 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.

* No sales charge is payable at the time of purchase on investments of
  $1,000,000 or more, although for such investments the Fund imposes a
  contingent deferred sales charge 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 million, plus 0.20% on the next $2 million and
  0.08% on the excess over $5 million. See "Purchasing Shares Of The
  Fund--Deferred Sales Charge Alternatives" for additional information with
  respect to contingent deferred sales charges.
    
 
  QUANTITY DISCOUNTS. Purchasers of Class A Shares may be entitled to reduced
initial sales charges through a combination of investments, rights of
accumulation or a Letter of Intent (even if an investor is not making an
investment of a size that normally would qualify for a quantity discount).
Investors, or their broker, dealer or financial intermediary, 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.

  For purposes of determining whether a purchase qualifies for a reduced initial
sales charge, the term "any person" is defined as any one of the following:
 
     (i)  an individual, their spouse and children under the age of 21, trust or
          custodial accounts established for any of their sole benefit(s) and 
          any corporation, partnership or sole proprietorship which is 100% 
          owned, either alone or in combination, by any of the foregoing; or
 
     (ii) a trustee or other fiduciary purchasing for a single trust estate
          (including a pension, profit-sharing or other employee benefit trust
          created pursuant to a plan qualified under Section 401 of the Internal
          Revenue Code, as amended); or
 
    (iii) a "company" as defined in Section 2(a)(8) of the Investment Company
          Act.
 
  1. Combination of Investments. Purchases of Class A Shares of the Fund, or
shares of other Van Kampen Merritt funds distributed by the Distributor subject
to an initial sales charge ("ISC Shares"), which are made at any one time by
"any person" may be combined to receive a quantity discount.
 
  2. Rights of Accumulation. Under the rights of accumulation, in determining
the sales charge to be paid for a current purchase of Class A Shares, "any
person" may combine their current purchase with the current public offering
price of Class A Shares of the Fund or ISC Shares, which are owned by such
person. If the account an investor is combining for rights of accumulation
differs from the account into which the investor's current purchase is placed,
the investor must indicate to the Transfer Agent the account number (and, if
applicable, fund name) of such other account.
 
  3. Letter of Intent. Purchasers of Class A Shares may qualify immediately for
a reduced sales charge by stating their intention to purchase an amount of Class
A Shares, during a 13 month period, that would qualify the investor for a
reduced sales charge. An investor may do this by signing a nonbinding Letter of
Intent, which may be signed at any time within 90 days after the first
investment to be included under the Letter of Intent. Class A Shares purchased
under the "Rights of Accumulation" described above (including investments in ISC
Shares) may be, at the time of the signing of the Letter of Intent, applied
towards completion of an investor's Letter of Intent. In addition, if an
investor's broker, dealer or financial intermediary and the Distributor agree to
refund the appropriate portion of their respective concessions to the Fund, the
sales charge on an investor's previous purchases made within 90 days may be
adjusted to the reduced sales charge under the Letter of Intent, and the
refunded concession will be used to purchase shares of the Fund at the public
offering price next determined after receipt of such monies. Each investment
made after signing the Letter of Intent will be entitled to the initial sales
charge applicable to the total investment indicated in the Letter of Intent. If
an investor does not complete the necessary purchases under the Letter of Intent
within 13 months from the date of the first purchase included thereunder, the
sales charge will be adjusted upward, corresponding to the amount actually
purchased.
 
                                       23
<PAGE>   466
 
  When an investor signs a Letter of Intent, Class A Shares of the Fund
purchased with a value of 5% of the amount specified in the Letter of Intent
will be restricted; that is, these Class A Shares cannot be sold or redeemed
until the Letter of Intent is satisfied or the additional sales charges have
been paid. If the total purchases made under the Letter of Intent, less
redemptions, equal or exceed the amount specified in the Letter of Intent, these
Class A Shares will no longer be restricted. If the total purchases, less
redemptions, exceed the amount so specified, and qualify an investor for a
further quantity discount, the Distributor and the investor's securities broker,
dealer or financial intermediary will, upon request, remit their respective
portions of the sales concession and with that amount, purchase additional Class
A Shares of the Fund for the investor's account at the next determined public
offering price. If an investor does not complete the necessary purchases under
the Letter of Intent, the sales charges will be adjusted upward and if, after
written notice, the investor does not pay the increased sales charge, sufficient
restricted Class A Shares will be redeemed to pay such charge.
 
  OTHER PURCHASE PROGRAMS. Purchasers of Class A Shares may be entitled to
reduced initial sales charges in connection with unit 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.
 
  1. Unit Trust Reinvestment Programs. The Fund permits unitholders of Florida
unit investment trusts to reinvest distributions from such trusts in Class A
Shares of the Fund at net asset value.
 
  The Fund permits unitholders of unit investment trusts to reinvest
distributions from such trusts in Class A Shares of the Fund and other ISC
Shares with no minimum initial or subsequent investment requirement, and with a
lower sales charge 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 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 dealer or broker, 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 securities broker or dealer 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 the Fund's transfer agent with
appropriate backup data for each participating investor in a computerized format
fully compatible with the transfer agent's 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
    
 
                                       24
<PAGE>   467
 
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.
 
2. NAV Purchase Options
 
  The classes of investors entitled to purchase shares of the Fund at net asset
value are as follows:
 
  (a) Current or retired Trustees/Directors of funds advised by Van Kampen
      American Capital Investment Advisory Corp., Van Kampen American Capital
      Asset Management, Inc. or John Govett & Co. Limited and such persons'
      families and their beneficial accounts. The term "families" includes a
      person's spouse, children and grandchildren, parents, and a person's
      spouse's parents.
 
   
  (b) Current or retired directors, officers and employees of VK/AC Holding,
      Inc. and any of its subsidiaries, Clayton, Dubilier & Rice, Inc.,

  (c) Directors, officers, employees and registered representatives of financial
      institutions that have a selling agreement with the Distributor and their
      spouses and minor children 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.
 
   
  (d) 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 the Fund alone, or in any combination of
      Class A Shares of the Fund and ISC Shares of other funds distributed by 
      the Distributor as described herein under "Purchasing Shares Of The
      Fund--Initial Sales Charge Alternative--Quantity Discounts," during the 13
      month period commencing with the first investment pursuant hereto equals
      at least $1 million. The Distributor may pay such entities through which
      purchases are made an amount up to 0.50% of the amount invested, over a
      twelve month period following such transaction.
    
 
  (e) Trustees and other fiduciaries purchasing shares for retirement plans of
      organizations with retirement plan assets of $10 million or more. The
      Distributor may pay commissions of up to 1% for such purchases.
 
  (f) Accounts as to which a selling firm charges an account management fee
      ("wrap accounts"), provided the selling firm has executed a supplemental
      agreement to their existing selling agreement with the Distributor.
 
  (g) 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.

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 other financial
intermediaries which percentage rate will be equal to (i) 1.00% with respect to
Class A Shares in an amount of $1 million or more; (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. Sales compensation with
respect to Class A Shares subject to a CDSC is set forth under "Purchasing
Shares Of The Fund--Initial Sales Charge Alternative."
 
  CDSC Shares redeemed within a specified period of time generally will be
subject to a contingent deferred sales charge at the rates set forth below. The
amount of the contingent deferred sales charge 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 contingent
deferred sales charge 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 contingent deferred sales charge 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 contingent deferred sales charge
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. Investors
should understand that the purpose of the contingent deferred sales charge and
the distribution fee with respect to a class of CDSC Shares is the same as the
initial sales charge and the distribution fee with respect to Class A Shares.
 
  In determining whether a contingent deferred sales charge 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 contingent deferred
 
                                       26
<PAGE>   469
 
sales charge 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, if any,
and fourth of CDSC Shares held longest during the period of time that a
contingent deferred sales charge 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).
 
  The contingent deferred sales charge is waived (i) on a redemption of shares
following the death of a shareholder, or (ii) to the extent that the redemption
represents a minimum required distribution from an IRA or other retirement plan
to a shareholder who has attained the age of 70 1/2.
 
   
  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 $1,000,000 or more,
although for such investments the Fund imposes a contingent deferred sales
charge 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 million, plus 0.20% on the next $2 million and 0.08% on the
excess over $5 million.
    
 
  CLASS B SHARES. Class B Shares redeemed within seven years of purchase
generally will be subject to a contingent deferred sales charge at the rates set
forth below, charged as a percentage of the dollar amount subject thereto:

  CLASS C SHARES. Class C Shares redeemed within the first twelve months of
purchase generally will be subject to a contingent deferred sales charge 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. Seven years after the end of the month in which a
shareholder's order to purchase a Class B Share of the Fund was accepted, such
Class B Share automatically will convert to a Class A Share and will no longer
be subject to the higher aggregate distribution and service fees. The purpose of
the conversion feature is to relieve the holders of Class B Shares that have
been outstanding for a period of time sufficient for the Distributor to have
been compensated for distribution expenses related to the Class B Shares from
most of the burden of such distribution-related expenses. The Fund does not
expect to issue any stock certificates upon conversion.
 
  For purposes of conversion of Class A Shares, Class B Shares purchased through
the reinvestment of dividends and distributions paid in respect of Class B
Shares in a shareholder's account will be considered to be held in a separate
sub-account. Each time any Class B Shares in the shareholder's account (other
than those in the sub-account) convert to Class A Shares, an equal pro rata
portion of the Class B Shares in the sub-account also will convert to Class A
Shares. The holding period applicable to a Class B Share acquired through the
use of the exchange privilege (discussed below) shall be the holding period
applicable to a Class B Share of such Fund acquired other than through use of
the exchange privilege. For purposes of calculating the holding period
applicable to a Class B Share of the Fund prior to conversion, a Class B Share
of the Fund issued in connection with an exercise of the exchange privilege, or
a series of exchanges, shall be deemed to have been issued on the date on which
the investor's order to purchase the exchanged Class B Share was accepted or, in
the case of a series of exchanges, when the investor's order to purchase the
original Class B Share was accepted.
 
  The conversion of Class B 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 services fee and transfer agency costs
with respect to Class B 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 Class B
Shares does not constitute a taxable event under federal income tax law. The
conversion of Class B Shares to Class A Shares may be suspended if such an
opinion is no longer available. In that event, no further conversions of Class B
Shares would occur, and Class B Shares might continue to be subject to the
higher aggregate distribution and service fees for an indefinite period.
 
- --------------------------------------------------------------------------------
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
    
 
                                       28
<PAGE>   471
 
   
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 the Fund's transfer agent receives payments for such shares.
However, shares become entitled to dividends on the day the Fund's transfer
agent 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 information under the "Distributions" section of the
Account Application bound in this Prospectus or available from State Street Bank
and Trust Company, c/o National Financial Data Services, Van Kampen Merritt
Funds, P.O. Box 419001, Kansas City, MO 64141-6001 (the "Transfer Agent"). After
the Transfer Agent 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 to the Transfer Agent. This election may be made by telephone by
calling 1-800-341-2911 or in writing to the Transfer Agent. For inquiries
through Telecommunications Device for the Deaf (TDD), dial 1-800-772-8889,
during the hours of 7:30 a.m. and 4:00 p.m. Central Standard Time. If a
shareholder elects to change the method of distribution, such change will be
effective only with regard to distributions for which the record date is seven
or more business days after the Transfer Agent has received the request. CDSC
Shares received as reinvested dividends are subject to a 12b-1 fee, a portion of
which may indirectly pay for the initial sales commission incurred on behalf of
the investor.
 
- --------------------------------------------------------------------------------
REDEMPTION OF SHARES
- --------------------------------------------------------------------------------
 
  WRITTEN REDEMPTION REQUEST. Shareholders may sell shares without charge (other
than, with respect to the CDSC Shares, any applicable contingent deferred sales
charge) at any
 
                                       29
<PAGE>   472
 
time by mailing a written redemption request in proper form to the Transfer
Agent. This request should be sent to State Street Bank and Trust Company, c/o
National Financial Data Services, Van Kampen Merritt Funds, P.O. Box 419001,
Kansas City, MO 64141-6001. The request should indicate the number of shares to
be redeemed of a particular fund and the class designations of such shares,
identify the account number and be signed exactly as the shares are registered.
If the amount being redeemed is in excess of $50,000 or if the redemption
proceeds will be sent to an address other than the address of record, the
signature(s) must be guaranteed by a member firm of a principal stock exchange,
a commercial bank or trust company which is a member of the Federal Deposit
Insurance Corporation, a credit union or a savings association. The guarantee
must state the words "Signature Guaranteed" along with the name of the granting
institution. Shareholders should verify with the institution that it is an
eligible guarantor prior to signing. A guarantee from a notary public is not
acceptable. If certificates are held for the shares being redeemed, such
certificates must be sent and endorsed for transfer or accompanied by an
endorsed stock power. Share certificates should be sent by registered mail to
National Financial Data Services, 1004 Baltimore Avenue, Dwight Building, Sixth
Floor, Kansas City, MO 64105-1807. Shareholders will receive the net asset value
per share next computed after the Transfer Agent receives the redemption request
and certificates (if any) in proper form. Any applicable contingent deferred
sales charge with respect to CDSC Shares redeemed will be deducted from the
redemption proceeds prior to transmittal of such proceeds to the shareholder.
 
   
  TELEPHONE REDEMPTIONS. Shareholders may sell shares by calling the Fund at
1-800-341-2911 before 3:00 p.m. Central Standard Time to request a redemption by
the Fund. For inquiries through Telecommunications Device for the Deaf (TDD),
dial 1-800-772-8889, during the hours of 7:30 a.m. and 3:00 p.m. Central
Standard Time. There is a $500 minimum and a $1,000,000 maximum per request if
the redemption proceeds are to be mailed to the shareholder. If the redemption
proceeds are to be wired to a bank there is a minimum of $5,000 and a $1,000,000
maximum per request. Prior to redeeming shares by telephone the "Expedited
Telephone Redemption" section of either the Account Application or Expedited
Telephone Redemption and Exchange Request Form (the "Authorization") must be
completed and on file with the Transfer Agent. The signature(s) on the
Authorization must be guaranteed by a member firm of a principal stock exchange,
a commercial bank or trust company which is a member of the Federal Deposit
Insurance Corporation, a credit union or a savings association unless the
Authorization is completed at the time an account is originally established. The
guarantee must state the words "Signature Guaranteed" along with the name of the
granting institution. Shareholders should verify with the institution that it is
an eligible guarantor prior to signing. A guarantee from a notary public is not
acceptable. A redemption requested by telephone will be processed at the net
asset value next determined after receipt of the request. Any applicable
contingent deferred sales charge with respect to CDSC Shares redeemed will be
deducted from the redemption proceeds prior to transmittal of such proceeds to
the shareholder. The proceeds would then be made payable to the registered
shareowner(s) and mailed to the address registered on the account or wired to a
bank, as requested on the Authorizations. Shareholders cannot
    
 
                                       30
<PAGE>   473
 
redeem shares by telephone if stock certificates are held for those shares. This
service is not available with respect to shares held in an Individual Retirement
Account for which State Street Bank and Trust Company acts as custodian. In
addition, this service is not available with respect to shares purchased by
check until 15 days after purchase.
 
   
  By establishing the telephone redemption service, a shareholder authorizes the
Fund or the Transfer Agent to act upon the instructions of any person by
telephone to redeem shares for any account for which such service has been
authorized to the address of record of such account or such other address as is
listed in the Authorization. The Fund, the Distributor, the Transfer Agent and
National Financial Data Services, Inc. ("NFDS") employ procedures reasonably
believed to confirm that instructions communicated by telephone are genuine.
Such procedures include requiring a person attempting to redeem shares by
telephone to provide, on a recorded line, the name on the account, a social
security number or tax identification number and such additional information as
may be included in the Authorization. In addition, a shareholder agrees that
none of the Fund, the Distributor, the Transfer Agent or National Financial Data
Services will be liable for any loss, liability, cost or expense arising out of
any request, including any fraudulent or unauthorized request. This service may
be amended or terminated at any time by the Transfer Agent or the Fund. If a
shareholder is unable to reach the Fund by telephone, he or she may redeem
shares pursuant to the procedures set forth above under the caption "Written
Redemption Request." During periods of extreme economic or market changes, it
may be difficult for investors to reach the Fund by telephone and to effect
telephone redemptions.
    
 
  REDEMPTION THROUGH DEALERS. Shareholders may sell shares (whether in
certificate or book-entry form) through their securities dealer, who will
telephone the request to the Distributor. Shareholders will receive the net
asset value next determined after such shareholder places the sell order. Any
applicable contingent deferred sales charge with respect to CDSC Shares redeemed
will be deducted from the redemption proceeds prior to transmittal of such
proceeds to the shareholder. It is the responsibility of the shareholder's
broker, dealer or financial intermediary to transmit the redemption order to the
Distributor. Because the Fund generally will determine net asset value once each
business day as of the close of business, sell orders placed through a
shareholder'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 shareholder's order to be fulfilled on the basis of the
net asset value to be determined that day. Any change in the redemption price
due to the failure of the Distributor to receive a sell order prior to such time
must be settled between the shareholder and the broker, dealer or financial
intermediary submitting the order. The Fund does not charge for this transaction
(other than any applicable contingent deferred sales charge). Shareholders must
submit a written redemption request in proper form to their securities dealer
within five business days after calling the dealer with the sell order. The
request should indicate the number of shares to be redeemed and the class
designation of such shares, identify the account number and the order or
confirmation number assigned to the trade and be signed by the shareholder
exactly as the shares are registered. If the amount of the redemption exceeds
$50,000 or if the redemption proceeds will be sent to an address other than the
address of record,
 
                                       31
<PAGE>   474
 
signature(s) must be guaranteed by a member firm of a principal stock exchange,
a commercial bank or trust company which is a member of the Federal Deposit
Insurance Corporation, a credit union or a savings association. The guarantee
must state the words "Signature Guaranteed" along with the name of the granting
institution. Shareholders should verify with the institution that it is an
eligible guarantor prior to signing. A guarantee from a notary public is not
acceptable. If certificates are held for the shares being redeemed, such
certificates must be sent endorsed for transfer or accompanied by an endorsed
stock power. Certificates should be sent by registered mail to State Street Bank
and Trust Company, c/o National Financial Data Services, Van Kampen Merritt
Funds, 1004 Baltimore Avenue, Dwight Building, Sixth Floor, Kansas City, MO
64105-1807. Shareholders whose shares are held in an Individual Retirement
Account ("IRA") for which State Street Bank and Trust Company acts as custodian
may not sell their shares through their securities dealers.
 
   
  REDEMPTION UPON DISABILITY. The Fund will waive the CDSC on Class B Share
redemptions following the disability of a Class B shareholder. An individual
will be considered disabled for this purpose if he or she meets the definition
thereof in Section 72(m)(7) of the Internal Revenue Code (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 Fund will
require satisfactory proof of disability before it determines to waive the CDSC
on Class B Shares.
    
 
   
  In cases of disability, the CDSC on Class B 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 death or initial determination of disability. This waiver of the CDSC on
Class B 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. Whether shares are redeemed by the Fund or sold through a securities
dealer, a check for the proceeds (net of any required tax withholding and, with
respect to CDSC Shares, any applicable contingent deferred sales charge)
ordinarily will be mailed to shareholders or their dealer, as the case may be,
within seven calendar days after a redemption request or repurchase order and
share certificates (if any) are received in proper form as set forth above. Wire
transfers from the Fund of redemption proceeds, in the manner described above,
ordinarily will be transmitted to the shareholder within one business day. If
any shares are redeemed or repurchased shortly after purchase, the Fund will not
mail the proceeds until checks received for the purchase of shares have cleared,
which may take 10 days or more. The proceeds, of course, may be more or less
than the cost of the shares.
 
  The right of redemption or resale to the Fund may be suspended or the date of
payment postponed during any period when the New York Stock Exchange is closed
(other than
 
                                       32
<PAGE>   475
 
customary weekend and holiday closings), when an emergency exists as defined by
rules and regulations of the SEC, or during any period when the SEC has by order
permitted such suspension or postponement.
 
  The Fund reserves the right to redeem any investment if the value of an
account falls below $500. Before the Fund makes such redemption it will provide
the shareholder with written notice and 30 days in which to make an additional
investment sufficient to increase the value of the account to at least $500.
 
- --------------------------------------------------------------------------------
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 a sub-trust. 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.

  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 trustees/directors, officers and employees to buy and sell
securities for their personal accounts subject to procedures designed to prevent
conflicts of interest including, in some instances, preclearance of trades.
 
   
  PORTFOLIO MANAGEMENT. David C. Johnson, a First 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 for the last five years. William V. Grady, a Vice
President of the Adviser, is primarily responsible for the day-to-day management
of the Fund's portfolio. Mr. Grady has been employed by the Adviser since 1992.
Prior to 1992, Mr. Grady was associated with the Municipal Bond Investors
Assurance Corporation, and prior to 1990, Mr. Grady was associated with Cigna
Investments, Inc.
    
 
- --------------------------------------------------------------------------------
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,
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
 
                                       35
<PAGE>   478
 
has sold or is selling shares of the Fund. See "Portfolio Transactions and
Brokerage Allocation" in the Statement of Additional Information for more
information.
 
- --------------------------------------------------------------------------------
THE 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 Investment
Company 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,
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, NASD
members or eligible non-members who are acting as brokers or agents and similar
agreements between the Fund and banks who are acting as brokers (collectively,
"Selling Agreements") that may provide for their customers or clients certain
services or assistance. Brokers, dealers and banks that have entered into
Selling Agreements with the Distributor and sell shares of the Fund are referred
to herein as "financial intermediaries."
 
  CLASS A SHARES. The Fund may spend an aggregate amount up to 0.30% 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 financial intermediaries and in connection with the
maintenance of such shareholders' accounts. The Fund pays the Distributor the
lesser of the balance of the 0.30% not paid to such 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 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 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
financial intermediary's customers. The Fund pays the Distributor the lesser of
the balance of 0.75% not paid to such financial intermediaries or the amount of
the Distributor's actual distribution related expense attributable to the
 
                                       36
<PAGE>   479
 
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 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 contingent deferred sales charge. 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. The Fund will disclose in its prospectus from
time to time the then current amount of any such unreimbursed expenses with
respect to each class of CDSC Shares expressed as a dollar amount and as a
percent of the Fund's total net assets. As of December 31, 1994, there were
$16,017 and $75 of unreimbursed distribution related expenses with respect to
Class B Shares and Class C Shares, respectively, representing 0.08% and 0.00% of
the Fund's total net assets. 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
contingent deferred sales charges.
    
 
  Because the Fund is a sub-trust of the Trust, amounts paid to the Distributor
as reimbursement for expenses of one sub-trust of the Trust may indirectly
benefit the other funds which are sub-trusts 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 contingent deferred sales charge
applicable to a particular class of CDSC Shares to defray distribution related
expenses attributable to any other class of CDSC 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
 
                                       37
<PAGE>   480
 
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.
 
- --------------------------------------------------------------------------------
TAX STATUS
- --------------------------------------------------------------------------------
 
FLORIDA TAXATION
 
  The following Florida tax discussion is based on the advice of Squire, Sanders
& Dempsey, special counsel to the Fund for Florida tax matters, and reflects
applicable Florida tax laws as of the date of this Prospectus.
 
  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.
 
  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 0.20%. 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, and reflects applicable tax laws as of the date of
this Prospectus.
 
  The Fund intends to qualify each year and to elect to be treated as a
regulated investment company under Subchapter M of the Internal Revenue Code of
1986, as amended (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 gains, but not net capital gain which is the
excess of net 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 net
investment 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. Similarly, the Fund will not be subject to federal
income tax on any net capital gain distributed to its shareholders. As a
sub-trust of a Massachusetts business trust, the Fund will not be subject to any
excise or income taxes in Massachusetts as long as it qualifies as a regulated
investment company for federal income tax purposes.
 
  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 (which does not
include tax-exempt income) for such year and at least 98% of its capital gain
net income (the latter of which is generally computed on the basis of the
one-year period ending on October 31 of such year), plus any required
distribution 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 was
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.
 
                                       39
<PAGE>   482
 
  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 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 closed out), 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.
 
  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 avoid income and excise taxes, the Fund may have to
dispose of securities that it would otherwise have continued to hold.
 
  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 gross income be derived from the disposition of securities
held for less than three months.
 
  DISTRIBUTIONS. If the Fund qualifies as a regulated investment company and
satisfies the 90% distribution requirement, and if, at the close of each quarter
of the Fund's taxable year, at least 50% of the total value of the Fund's assets
consists of obligations the interest on which is exempt from federal income tax
("tax-exempt obligations"), the Fund will be qualified to pay exempt-interest
dividends to its shareholders to the extent of its tax-exempt interest income
(less expenses applicable thereto). Exempt-interest dividends are excludable
from a shareholder's gross income for federal income tax purposes, but may be
taxable distributions for state, local and other tax purposes. Exempt-interest
dividends are included, however, 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. Interest expense with respect to
indebtedness incurred or continued by a shareholder to purchase or carry shares
of the Fund is not deductible to the extent that such interest relates to
exempt-interest dividends received from the Fund.
 
  The Internal Revenue Service has publicly ruled that payments of insurance
proceeds representing interest on defaulted tax-exempt obligations are
excludable from gross income to the same extent that such payments would have
been excludable if they had been directly made by the issuer of the insured
obligations. Accordingly, insurance proceeds received by the Fund from any
insurer with whom the Fund maintains a policy described in this Prospectus will
be tax-exempt interest income of the Fund to the same extent as if such payments
were made by the issuer of the insured obligations, and will be includable by
the Fund in calculating their exempt-interest dividends. In the case of
 
                                       40
<PAGE>   483
 
non-appropriation by a political subdivision, however, there can be no assurance
that payments made by the insurers representing interest on a
"non-appropriation" lease obligation will be excludable from gross income for
federal income tax purposes and, therefore, includable by the Fund in
calculating its tax-exempt dividends.
 
  Distributions of the Fund's investment company taxable income (which does not
include tax-exempt interest income) are taxable to shareholders as ordinary
income whether received in shares or in cash. Shareholders who receive
distributions in the form of additional shares will have a basis for federal
income tax purposes in each such share equal to the value thereof on the
reinvestment date. Distributions of the Fund's net capital gain ("capital gains
dividend"), if any, are taxable to shareholders at the rates applicable to
long-term capital gains regardless of the length of time shares of the Fund have
been held by such shareholders. All or a portion of the Fund's gain from the
sale or redemption of tax-exempt obligations purchased at a market discount will
be treated as ordinary income rather than capital gain. 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 shareholders (assuming such shares are held as
a capital asset). It is not expected that any portion of the distributions from
the Fund will be eligible for the dividends received deduction for corporations.
The Fund will inform shareholders of the source and tax status of distributions
promptly after the close of each calendar year.
 
  Exempt-interest dividends allocable to interest received by the Fund on
certain "private activity" obligations issued after August 7, 1986 will be
treated as interest on such obligations and thus will give rise to an item of
tax preference that will increase a shareholder's alternative minimum taxable
income. In addition, for corporations, alternative minimum taxable income will
be increased by a percentage of the amount by which a measure of income that
includes interest on tax-exempt obligations exceeds the amount otherwise
determined to be the alternative minimum taxable income. Accordingly, investment
in the Fund may cause such shareholders to be subject to (or result in an
increased liability under) the alternative minimum tax.
 
  Exempt-interest dividends will not be tax-exempt to the extent made to any
shareholder who is a "substantial user" of the facilities financed by tax-exempt
obligations held by the Fund or "related persons" of such substantial users.
 
  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 a month and paid in 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 is actually made.
 
                                       41
<PAGE>   484
 
  The Fund is required, in certain circumstances, to withhold 31% of taxable
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. Redemption or sale of shares of the Fund will be a taxable
transaction for federal income tax purposes. Redeeming shareholders will
generally recognize gain or loss in an amount equal to the difference between
their basis in such redeemed shares of the Fund 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 generally be long-term if such shares have been held for more than
one year. Any loss realized on a taxable disposition of shares held for six
months or less will be disallowed to the extent of any exempt-interest dividends
received with respect to such shares. If such loss is not entirely disallowed,
it will be treated as a long-term capital loss to the extent of any capital gain
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 Florida and federal tax discussions set forth above are for
general information only. Prospective investors should consult their tax
advisers regarding the specific Florida and federal tax consequences of holding
and disposing of shares, as well as the effects of other state, local and
foreign tax laws and any proposed tax law changes.
 
- --------------------------------------------------------------------------------
SHAREHOLDER PROGRAMS
- --------------------------------------------------------------------------------
 
   
  SHARE CERTIFICATES.  As a rule, the Fund will not issue share certificates.
Upon written or telephone request to the Fund, however, 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 State Street Bank and Trust Company, c/o National Financial Data
Services, P.O. Box 419001, Kansas City, MO 64141-6001, Attn: Van Kampen Merritt
Funds, requesting an "affidavit of loss" and to obtain a Surety Bond in a form
acceptable to the Transfer Agent. On the date the letter is received the
Transfer Agent will calculate no more than 2.00% of the net asset value of the
issued shares, and bill the party to whom the certificate was mailed.
    
 
   
  SYSTEMATIC WITHDRAWAL PROGRAM.  If a shareholder's Class A Share account or
Class B Share account is valued at $10,000 or more, such shareholder's dividends
are being reinvested, a requested dollar amount may be paid from such account to
any person monthly, quarterly, semiannually or annually. The minimum amount that
may be withdrawn each period is $50; withdrawals will be made on the seventh
business day of the month in which they are scheduled to occur. Depending upon
the size of the payments requested and the fluctuations in the net asset value
of the shares redeemed, redemptions for the purpose of making such payments may
reduce or even exhaust the amounts in such
    
 
                                       42
<PAGE>   485
 
account. If an investor acquires additional shares of the Fund after joining the
Systematic Withdrawal Program, the investor must inform the Fund if he or she
wants the new shares to be subject to the Systematic Withdrawal Program by
telephoning the Fund at 1-800-341-2911.
 
   
  With respect to redemptions of Class B Shares made pursuant to the Systematic
Withdrawal Program, an investor may annually redeem up to 12% of the net asset
value of the investor's initial investment in Class B Shares or, if the investor
does not join the program on the date of his or her initial investment, the net
asset value of the investor's Class B Shares on the date the investor elects to
participate in the Systematic Withdrawal Program. The Fund will waive the
contingent deferred sales charge applicable to Class B Shares redeemed pursuant
to the Fund's Systematic Withdrawal Program.
    
 
  It will ordinarily be disadvantageous to purchase shares (except through
reinvestment of distributions) while participating in a systematic withdrawal
program because a shareholder will be paying a sales charge, or will become
subject to a contingent deferred sales charge, in order to purchase shares at
the same time that shares are being redeemed upon which a sales charge may
already have been paid. Therefore, the Fund will not knowingly permit a
shareholder to make additional investments in shares of less than $5,000 if at
the same time such shareholder is making systematic withdrawals at a rate
greater than the distribution being paid on such shareholder's shares. The Fund
reserves the right to amend or terminate the systematic withdrawal program on
thirty days' notice, and a shareholder may withdraw from the program at any
time.
 
  EXCHANGE PRIVILEGE.  Any Class A Shares of the Fund which have been registered
in a shareholder's name for at least 15 days will be able to be exchanged for
ISC Shares of other Van Kampen Merritt mutual funds distributed by the
Distributor that offer an exchange privilege. Under the exchange privilege, the
Fund will offer to exchange its Class A Shares for ISC Shares on the basis of
relative net asset value per share. Any ISC Shares exchanged into the Fund that
have been charged a sales load lower than the sales load applicable to Class A
Shares of the Fund will be charged the applicable sales load differential upon
exchange. ISC Shares of the Van Kampen Merritt Money Market Fund and Van Kampen
Merritt Tax Free Money Fund which have not previously been charged a sales load
(except for shares purchased via the reinvestment option) will be charged the
applicable sales load upon exchange into the Fund.
 
  Class B Shareholders of the Fund may exchange their Class B Shares
("Outstanding Class B Shares") for Class B Shares of other Van Kampen Merritt
mutual funds sponsored by the Distributor ("New Class B Shares") on the basis of
relative net asset value per Class B Share, without the payment of any
contingent deferred sales charge that might otherwise be due on redemption of
the Outstanding Class B Shares. Class B Shares of a fund acquired through use of
the exchange privilege will be 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.
 
  Class C Shares of the Fund are exchangeable for Class C Shares of other Van
Kampen Merritt mutual funds distributed by the Distributor on the same terms set
forth in the
 
                                       43
<PAGE>   486
 
   
preceding paragraph with respect to Class B Shares, except that Class C Shares
do not convert to Class A Shares. The exchange privilege with respect to any Van
Kampen Merritt money market fund sponsored by the Distributor is not available
for Class C Shareholders.
    
 
   
  In order to qualify for the exchange privilege, it is required that the share
being exchanged have a net asset value of at least $1,000 (unless prior approval
has been obtained from the Fund). Shareholders will be able to effect an
exchange by telephone by calling the Fund at 1-800-341-2911 prior to 3:00 p.m.
Central Standard Time. For inquiries through Telecommunications Device for the
Deaf (TDD) dial 1-800-772-8889, during the hours of 7:30 a.m. and 3:00 p.m.
Central Standard Time. The exchange will be processed at the net asset value
next determined after receipt of such request. By utilizing the telephone
exchange service, a shareholder authorizes the Fund or the Transfer Agent to act
upon the instructions of any person by telephone to exchange shares from any
account for which such service has been authorized to any identically registered
account(s) with any Van Kampen Merritt fund distributed by the Distributor that
offers an exchange privilege. In addition, a shareholder agrees that none of the
Fund, the Distributor, the Transfer Agent or National Financial Data Services
("NFDS") will be liable for any loss, liability, cost or expense arising out of
any request, including any fraudulent request. The staff of the SEC currently is
reviewing its position with respect to such agreements. This service may be
amended or terminated at any time by the Transfer Agent or the Fund. If a
shareholder has certificates for any shares being exchanged, such certificates
must be surrendered prior to the exchange in the same manner as in redemption of
such shares. See "Redemption of Shares--Telephone Redemptions". Any shares
exchanged between the Fund and any of the other funds will begin earning
dividends on the next business day after the exchange is effected. 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.
    
 
  An exchange between Van Kampen Merritt funds pursuant to the exchange
privilege is treated as a sale for federal income tax purposes and, depending
upon the circumstances, a short- or long-term capital gain or loss may be
realized.
 
  The exchange privilege may be modified or terminated at any time, subject to
the requirement that the Fund give prominent notice thereof at least 60 days
prior to the effective date of the modification or termination in certain
circumstances. The Fund reserves the right to limit the number of times a
shareholder may exercise the exchange privilege.
 
  AUTOMATED MULTIPLE ACCOUNT SHAREHOLDER SERVICES (AMASSSM).
 
   
  1. 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
    
 
                                       44
<PAGE>   487
 
   
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 the Transfer Agent 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 the Transfer Agent.
    
 
  2. Automated Dividend Programs.  The Fund will, upon the election of a
shareholder, automatically invest distributions from a shareholder's account
directly into a shareholder's bank account.
 
   
  3. Dividend Diversification.  Monthly distributions and any net long-term
capital gain distributions to a shareholder's account may be invested in the
same class of shares of any other Van Kampen Merritt mutual fund distributed by
the Distributor at the then current net asset value, WITHOUT A SALES CHARGE,
upon election by a shareholder. This election may be made on the account
application bound in this Prospectus, by written notice to the Transfer Agent or
by calling the Fund directly at 1-800-341-2911, during the hours of 7:00 a.m. to
7:00 p.m. Central Standard Time. For inquiries through Telecommunications Device
for the Deaf (TDD) dial 1-800-772-8889. In order to qualify for this privilege,
a shareholder must have established an account in the other mutual fund prior to
electing this privilege. This privilege may be modified or terminated by the
Fund at any time.
    
 
  4. Easy Account Savings Enhancement Plan (EASESM).  Once a shareholder has
opened an account with the minimum $1,000 investment, the automatic investment
option may be utilized to make regular electronic monthly investments of $100 or
more into such shareholder's account with the Fund. In order to utilize this
option, a shareholder must fill out and sign the appropriate section of the
application attached to this Prospectus or the EASESM application which is
available from the Transfer Agent, the Fund, such shareholder's broker or dealer
or the Distributor. Once the Transfer Agent has received this application, such
shareholder's checking account at his or her designated local bank will be
debited each month in the amount authorized by such shareholder to purchase
shares of the Fund. Once enrolled in the EASESM program, a shareholder may
change the monthly amount or terminate participation at any time by writing or
calling the Transfer Agent. Shareholders in the EASESM program will receive a
confirmation of these transactions from the Fund monthly, and their regular bank
account statements will show the debit transaction each month.
 
  By electing to utilize any of the foregoing services, a shareholder authorizes
the Transfer Agent or its agent to act upon the instructions indicated in the
appropriate section of the Application in performing such services by either
withdrawing funds for deposit in the Fund pursuant to the EASESM Plan or
depositing distributions and redemptions in the bank account indicated by the
voided check or deposit slip accompanying the shareholder's election or by
depositing the shareholder's distributions in the Van Kampen Merritt fund
account indicated. A shareholder also agrees that neither the Fund, the
Distributor, the Transfer Agent nor NFDS will be liable for any loss, liability,
cost or
 
                                       45
<PAGE>   488
 
expense arising out of any request, including any fraudulent request. This
service may be amended or terminated at any time by the Transfer Agent or by the
Fund.
 
  REINSTATEMENT PRIVILEGE.  A shareholder who has redeemed Class A Shares or
Class B Shares may, within 120 days, repurchase Class A Shares of the Fund, or
shares of other Van Kampen Merritt mutual funds distributed by the Distributor,
in an amount of at least $500 and not exceeding the redemption proceeds
received, at a purchase price equal to the net asset value next determined after
the reinstatement request is received by the Transfer Agent or the Distributor.
A Class C Shareholder who has redeemed shares of the Fund may repurchase Class C
Shares of the Fund, or shares of other Van Kampen Merritt mutual funds
distributed by the Distributor with credit given for any contingent deferred
sales charge paid upon such redemption.
 
- --------------------------------------------------------------------------------
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., Business Week, Forbes or other industry 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.

SHAREHOLDER SERVICES

  State Street Bank and Trust Company, c/o National Financial Data Services,
P.O. Box 419001, Kansas City, MO 64141-6001, transfer agent for the Fund,
performs bookkeeping, data processing and administrative services related to the
maintenance of shareholder accounts. When an initial investment is made in the
Fund, an account will be opened for each shareholder on the Fund's books and
shareholders will receive a confirmation of the opening of the account.
Shareholders will receive monthly statements giving details of all activity in
their account(s) and will also receive a statement whenever an investment or
withdrawal is made in or from their account. Information for federal income tax
purposes will be provided at the end of the year. Such statements will present
separately information with respect to each class of the Fund's shares. It is
expected that the transfer agency costs attributable to the Class B Shares and
Class C Shares will be higher than the transfer agency costs attributable to the
Class A Shares.
- --------------------------------------------------------------------------------
DESCRIPTION OF SHARES OF THE FUND
- --------------------------------------------------------------------------------
 
  The Fund is a sub-trust of the Van Kampen Merritt Tax Free Fund, a
Massachusetts business trust organized August 15, 1985 (the "Trust"). Shares of
the Trust entitle their holders to one vote per share; however, separate votes
are taken by each sub-trust on matters affecting an individual sub-trust.
 
  The authorized capitalization of the Fund consists of an unlimited number of
shares of beneficial interest, without 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 "The
Distribution and Service Plans."
 
  Pursuant to an order of the SEC, 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 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 Class B Shareholders 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 a majority of the shares present and voting at
such meeting. The Trust will assist such
 
                                       47
<PAGE>   490
 
holders in communicating with other shareholders of the Fund to the extent
required by the Investment Company Act. More detailed information concerning the
Trust is set forth in the Statement of Additional Information.
- --------------------------------------------------------------------------------
SHAREHOLDER REPORTS AND INQUIRIES
- --------------------------------------------------------------------------------
 
  The fiscal year of the Fund ends December 31. The Fund sends to its
shareholders, at least semi-annually, reports showing the Fund's portfolio and
other information. An annual report, containing financial statements audited by
Independent Auditors, 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.

                      STATEMENT OF ADDITIONAL INFORMATION
 
            VAN KAMPEN MERRITT FLORIDA INSURED TAX FREE INCOME FUND
 
  The Van Kampen Merritt Florida Insured Tax Free Income Fund (the "Fund") seeks
to provide investors with high 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 reside in Florida for tax
purposes. The Fund attempts to achieve its investment objective by investing at
least 80% of its assets in a portfolio of Florida insured 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"). Insured 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.
Up to 20% of the Fund's total assets may consist of uninsured Florida municipal
securities rated investment grade at the time of investment. There is no
assurance that the Fund will achieve its investment objective. The Fund is a
separate sub-trust of Van Kampen Merritt Tax Free Fund, a Massachusetts business
trust (the "Trust").
 
   
  This Statement of Additional Information is not a prospectus, but should be
read in conjunction with the Prospectus for the Fund dated April 30, 1995 (the

information that a prospective investor should consider before purchasing shares
of the Fund, and investors should obtain and read the Prospectus prior to
purchasing shares. A copy of the Prospectus may be obtained without charge, by
calling 1-800-341-2911. This Statement of Additional Information incorporates by
reference the entire Prospectus.
    
 
  The Prospectus and this Statement of Additional Information omit certain of
the information contained in the registration statement filed with the
Securities and Exchange Commission, Washington, D.C. (the "SEC"). These items
may be obtained from the SEC upon payment of the fee prescribed, or inspected at
the SEC's office at no charge.

                             THE FUND AND THE TRUST
 
   
  The Fund is a separate sub-trust of the Trust, an open-end non-diversified
management investment company. At present, the Fund, Van Kampen Merritt Insured
Tax Free Income Fund, Van Kampen Merritt Tax Free High Income Fund, Van Kampen
Merritt Municipal Income Fund, Van Kampen Merritt Limited Term Municipal Income
Fund, Van Kampen Merritt California Insured Tax Free Fund, Van Kampen Merritt
New York Tax Free Income Fund, and Van Kampen Merritt New Jersey Tax Free Fund
have been organized as sub-trusts of the Trust and that have commenced
investment operations. Van Kampen Merritt California Tax Free Income Fund, Van
Kampen Merritt Michigan Tax Free Income Fund, Van Kampen Merritt Missouri Tax
Free Income Fund, and Van Kampen Merritt Ohio Tax Free Income Fund have been
organized as sub-trusts of the Trust but have not commenced investment
operations. Other sub-trusts may be organized and offered in the future.
    
 
  The Trust is an unincorporated business trust established under the laws of
the Commonwealth of Massachusetts by a Declaration of Trust dated August 15,
1985. The Declaration of Trust permits the Trustees to issue an unlimited number
of full and fractional shares in separate sub-trusts. Each share represents an
equal proportionate interest in the assets of the sub-trust with each other
share in such sub-trust and no interest in any other sub-trust. No sub-trust is
subject to the liabilities of any other sub-trust. The Declaration of Trust
provides that shareholders are not liable for any liabilities of the Trust or
any of its sub-trusts, requires inclusion of a clause to that effect in every
agreement entered into by the Trust or any of its sub-trusts 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 sub-trust on matters affecting an individual
sub-trust. For example, a change in investment policy for a sub-trust would be
voted upon by shareholders of only the sub-trust involved. 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 a majority of the shares present and voting at
such meeting.
 
  The Trustees may amend the Declaration of Trust (including with respect to any
sub-trust) in any manner without shareholder approval, except that the Trustees
may not adopt any amendment adversely affecting the rights of shareholders of
any sub-trust without approval by a majority of the shares of each affected
sub-trust present at a meeting of shareholders (or such higher vote as may be
required by the Investment Company Act of 1940, as amended (the "Investment
Company 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 bond
      market; however, the Fund will not invest more than 25% of its assets in
      industrial development bonds in a single industry.
 
   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
 
                                       B-2
<PAGE>   494
 
      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
      Securities and Exchange Commission (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.
 
   8. Invest in securities of other investment companies, except as part of a
      merger, consolidation or other acquisition and except that the Fund may
      invest up to 10% of its assets in tax-exempt investment companies that
      invest in securities rated comparably to those the Fund may invest in so
      long as the Fund does not own more than 3% of the outstanding voting stock
      of any tax-exempt investment company or securities of any tax-exempt
      investment company aggregating in value more than 5% of the total assets
      of the Fund.
 
   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 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 outstanding 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
 
                                       B-3
<PAGE>   495
 
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 municipal 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. 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
 
                                       B-4
<PAGE>   496
 
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 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, 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.
 
                                       B-5
<PAGE>   497
 
  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. 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 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
 
                                       B-6
<PAGE>   498
 
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.
 
  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
 
                                       B-7
<PAGE>   499
 
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 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.
 
                                       B-8

  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 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.
 
  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; however, unemployment levels during the
past several years have been above the national level and are estimated to
continue to be above the national level for the State's 1994-95 fiscal year
which ends June 30, 1995. 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, 1993, Florida ranks fourth with an estimated population
of 13.6 million. Since 1980, the State's population has increased approximately
40%. 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.
 
   
  Personal income growth in Florida is estimated at 8.3% and 6.7% for 1994-95
and 1995-96 respectively. By the end of the State's fiscal year 1995-96, real
personal income per capita in Florida is projected to average 4.5% higher than
the 1993-94 level.
    
 
  Florida's economic dependence on the cyclical construction and construction
related manufacturing sectors had declined. The service sector is Florida's
largest employer. Presently, the State's service sector employment constitutes
32.6% of the total non-farm employment. While structurally the southeast and the
nation are endowed with a greater proportion of manufacturing jobs, which tend
to pay higher wages, service jobs are less sensitive to business cycle swings.
 
   
  Since 1980, Florida's unemployment rate has generally tracked below that of
the nation; however, since 1989 the State's jobless rate has moved ahead of the
national average. The average rate of unemployment for Florida since 1980 is
6.5% while the national average during the same time period is 7.1%. Florida's
unemployment rate is forecasted at 6.1% for both fiscal year 1994-95 and fiscal
year 1995-96.
    
 
   
  TOURISM INDUSTRY.  Tourism is one of Florida's most important industries.
Approximately 41 million people visited the State in 1993, as reported by the
Florida Department of Commerce. In terms of business activities and Florida tax
revenues, tourism in Florida in 1993 was equivalent to an estimated 4.5 million
additional residents, spending their dollars predominantly at eating and
drinking establishments, hotels and motels, and amusement and recreation parks.
Florida tourism is currently suffering from the effects of negative publicity
regarding crime against tourists in the State. However, unlike in fiscal year
1993-94 which experienced a 4.0% drop in the number of tourists, zero growth in
the number of tourists is expected over the current fiscal year. A 1.7% growth
in the number of tourists is expected in 1995-96.

  STATE FINANCIAL OPERATIONS.  Financial operations of the State covering all
receipts and expenditures are maintained through the use of three funds--the
General Revenue Fund, Trust Funds, and the Working Capital Fund. Article III of
the Florida Constitution adds a fourth fund, the Budget Stabilization Fund. In
fiscal year 1993-94, 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 66%, 8%,
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 1993-94, appropriations from the General Revenue Fund for education, health
and welfare, and public safety amounted to approximately 49%, 32%, and 12%,
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, 1994, receipts from the sales
and use tax were $10,012.5 million, an increase of 6.9% from fiscal year
1992-93.
 
   
  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, 1994 were
$1,733.4 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 $439.8
million in the State fiscal year ended June 30, 1994. The receipts of corporate
income tax for the State fiscal year ended June 30, 1994 were $1,047.4 million,
an increase of 23.7% 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
1993-94 produced ticket sales of $2.15 billion of which education received
approximately $816.2 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 1994-95 General Revenue plus Working Capital and Budget
Stabilization funds available total $14,682.9 million, 6.1% increase over
1993-94. This amount reflects a transfer of $159.0 million in non-recurring
revenue due to Hurricane Andrew, to a hurricane relief trust fund. The $13,702.1
million Estimated Revenues (excluding the Hurricane Andrew impacts) represent an
increase of 6.6% over the analogous figure in 1993-94. With combined General
Revenue, Working Capital Fund and Budget Stabilization Fund appropriations at
$14,309.7 million, unencumbered reserves at the end of the fiscal year are
estimated at $373.2 million.
    
 
   
  In fiscal year 1995-96 estimated General Revenue plus Working Capital and
Budget Stabilization funds available total $14,915.4 million, a 1.6% increase
over 1994-95. The $14,465.2 million in Estimated Revenues represent a 5.6%
increase over the analogous figure in 1994-95.
    
 
   
  According to the Division of Bond Finance of the Department of General
Services of the State, as of April 4, 1995, the State maintains a high bond
rating from Moody's Investors Service, Inc. (Aa), Standard & Poor's Corporation
(AA) and Fitch Investors Service (AA) on the majority of its full faith and
credit bonds. Outstanding full faith and credit bonds at April 4, 1995 totalled
approximately $6.55 billion, with another $300 million anticipated to be issued
April 25, 1995.

  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.
 
  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 "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
 
                                      B-12
<PAGE>   504
 
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
 
                                      B-13
<PAGE>   505
 
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
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.

<PAGE>   506
 
  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 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
 
                                      B-15
<PAGE>   507
 
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 Investment Company 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 high-grade 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 high-grade 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, high-grade assets equal to the exercise price.
 
                                      B-16
<PAGE>   508
 
  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 high-grade 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 Internal Revenue 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 Standard & Poor's 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.
 
                                      B-17
<PAGE>   509
 
        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 having predominantly
    B         speculative with respect to capacity to pay interest and repay principal. 'BB'
    CCC       indicates the lowest degree of speculation and 'C' the highest. While such debt
    CC        will likely have some quality and protective characteristics, these are
    C         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.
</TABLE>
    
 
                                      B-18
<PAGE>   510
 
<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 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.
    
 
                                      B-19
<PAGE>   511
 
          -- 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.
 
    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.
</TABLE>
    
 
     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.
 
    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.
 
    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 senior debt obligations which have an original maturity
     not exceeding one year. Obligations relying upon support mechanisms such as
     letters-of-credit and bond 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 (or supporting institutions) have a superior
        ability for repayment of senior short-term debt obligations.
 
             Issuers rated Prime-2 (or supporting institutions) have a strong
        ability for repayment of senior short-term debt obligations.
 
             Issuers rated Prime-3 (or supporting institutions) have an
        acceptable ability for repayment of senior short-term debt obligations.
 
          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.
 
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.

* Interested persons of each respective Fund as defined in the Investment
Company Act of 1940.
 
  Each of the foregoing trustees of the Fund acts as a trustee for other
investment companies advised by the Adviser, and each of the foregoing officers
holds the same positions with other investment companies advised by the Adviser.
 
  The compensation of the officers and trustees who are affiliated persons (as
defined in the Investment Company Act) of the Adviser is paid by the Adviser,
and the compensation of the officers and trustees who are affiliated persons of
Van Kampen American Capital Distributors, Inc. or Van Kampen American Capital,
Inc. is paid by the respective entity. The Fund pays the compensation of all
other officers and trustees of the Fund. During the next year, the Fund expects
to pay trustees who are not affiliated persons of the Adviser, Van Kampen
American Capital Distributors, Inc. or Van Kampen American Capital, Inc. $2,500
per year, and
 
                                      B-25

$250 per meeting of the Board of Trustees, plus expenses. Under the Fund's
retirement plan, trustees who are not affiliated with the Adviser, Van Kampen
American Capital Distributors, Inc. or Van Kampen American Capital, Inc., have
at least ten years of service and retire at or after attaining the age of 60,
are eligible to receive a retirement benefit equal to the annual retainer for
each of the ten years following such trustee's retirement. Under certain
conditions, reduced benefits are available for early retirement. Under the
Fund's deferred compensation plan, a trustee who is not affiliated with the
Adviser, Van Kampen American Capital Distributors, Inc. or Van Kampen American
Capital, Inc. can elect to defer receipt of all or a portion of the trustee's
fees earned by such trustee until such trustee's retirement. The deferred
compensation earns a rate of return determined by reference to the Fund or other
Van Kampen Merritt mutual funds advised by the Adviser as selected by the
trustee. To the extent permitted by the Investment Company Act, the Fund may
invest in securities of other Van Kampen Merritt mutual funds advised by the
Adviser 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.

(1)     Messrs. Merritt and McDonnell, Trustees of each Fund during fiscal year
      1994, are affiliated persons of the Adviser and are not eligible for
      compensation or retirement benefits from the Funds.
    
 
   
(2)     The Registrant is Van Kampen Merritt Tax Free Fund (the "Trust") which
      currently is comprised of 8 sub-trusts, including the Fund. The amounts
      shown in this column are accumulated from the Aggregate Compensation of
      each of these 8 sub-trusts during such sub-trust's last completed fiscal
      year prior to the date of this Statement of Additional Information.
      Beginning in October 1994 each Trustee, except Messrs. Gaughan and Whalen,
      began deferring his entire aggregate compensation paid by the Fund. The
      total combined amount of deferred compensation (including interest)
      accrued with respect to each Trustee as of December 31, 1994 is as
      follows: Mr. Kennedy $14,737; Mr. Miller $14,553; Mr. Nelson $14,737 and
      Mr. Robinson $13,725.
    
 
   
(3)     The Retirement Plan commenced as of August 1, 1994 for the Fund. As of
      the end of the Fund's 1994 fiscal year, no amounts had been accrued for
      retirement benefits because such amounts were either zero or considered to
      be immaterial to the net assets of the Fund at such time. During the
      Fund's 1995 fiscal year, the Fund will accrue amounts for retirement
      benefits and include an amount, if any, for such Fund's 1994 fiscal year.
    
 
   
(4)     This is the estimated annual benefits payable per year for the 10-year
      period commencing in the year of such Trustee's retirement by a Fund
      assuming: the Trustee has 10 or more years of service on the Board of the
      Fund, retires at or after attaining the age of 60 and the annual retainer
      in the year prior to the Trustee's retirement is $2,500. Trustees retiring
      prior to the age of 60 or with fewer than 10 years of service for the Fund
      may receive reduced retirement benefits from such Fund.
    
 
   
(5)     The Fund Complex consists of 20 mutual funds advised by the Adviser. The
      amounts shown in this column are accumulated from the Aggregate
      Compensation of each of these 20 mutual funds in the Fund Complex during
      each fund's last completed fiscal year prior to the date of this Statement
      of Additional Information. The Adviser also serves as investment adviser
      for other mutual funds and closed-end investment companies; however, with
      the exception of Messrs. Merritt, McDonnell and

      Whalen, such mutual funds and closed-end investment companies do not have
      the same trustees as the Fund Complex. Combining the Fund Complex with
      other mutual funds and investment companies advised by the Adviser, Mr.
      Whalen received Total Compensation of $161,850.
    
 
   
  As of April 13, 1995, the trustees and officers as a group own less than 1% of
the shares of the Fund.
    
 
   
  No officer or trustee of the Fund owns or would be able to acquire 5% or more
of the common stock of VK/AC Holding, Inc.

Capital, Inc. own, in the aggregate, not more than 6% of the common stock of
VK/AC Holding, Inc. and have the right to acquire, upon the exercise of options,
approximately an additional 10% of the common stock of VK/AC Holding, Inc.
 
  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 sub-trust, 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 sub-trust
(or by the Fund's shareholders), and by the disinterested trustees in compliance
with the requirements of the Investment Company 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 period ended December 31, 1994 the Fund recognized advisory expenses
of $0.
    
 
OTHER AGREEMENTS
 
  SUPPORT SERVICES AGREEMENT.  Under a support services agreement with the
Distributor the Fund receives support services for shareholders, including the
handling of all written and telephonic communications, except initial order
entry and other distribution related communications. Upon entering into such
agreement, the Fund realized a reduction in the fee which would have been paid
to the Transfer Agent if the Transfer Agent had provided such services. Payment
by the Fund for such services is made on cost basis for the employment of the
personnel and the equipment necessary to render the support services. The Fund,
and the other Van Kampen Merritt mutual funds distributed by the Distributor,
share such costs proportionately among themselves based upon their respective
net asset values.
 
   
  For the period ended December 31, 1994 the Fund recognized expenses of
approximately $4,680, representing the Distributor's cost of providing certain
support services.
    
 
   
  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 Merritt mutual funds
distributed by the Distributor 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 Merritt funds based proportionally on
their respective net assets.
    
 
   
  For the period ended December 31, 1994 the Fund recognized expenses of
approximately $942, representing the Adviser's cost of providing accounting
services.
    
 
  LEGAL SERVICES AGREEMENT.  The Fund has entered into a Legal Services
Agreement pursuant to which Van Kampen American Capital, Inc. 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 Fund. 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. The
Fund, and the other Van Kampen Merritt mutual funds distributed by the
Distributor, share one half (50%) of such costs equally. The remaining one half
(50%) of such costs are allocated to specific funds based on specific time
allocations, or in the event services are attributable only to
 
                                      B-28

types of funds (i.e. closed-end or open-end), the relative amount of time spent
on each type of fund and then further allocated between funds of that type based
upon their respective net asset values.
 
   
  For the period ended December 31, 1994 the Fund recognized expenses of
approximately $0, representing Van Kampen American Capital, Inc.'s cost of
providing legal services.
    
 
CUSTODIAN AND INDEPENDENT AUDITORS
 
  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 auditors for the Fund are KPMG Peat Marwick LLP, Chicago,
Illinois. The selection of independent auditors 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 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 sub-trust.
 
                                      B-29
<PAGE>   521
 
   
  The trustees have adopted certain policies incorporating the standards of Rule
17e-1 issued by the SEC under the Investment Company 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 each of its sub-trusts, including the Fund, will be treated as
separate corporations for income tax purposes. The Fund may be subject to tax if
it fails to distribute net capital gains, or if its annual distributions, as a
percentage of its income, are less than the distributions required by tax laws.
 
  The table below illustrates approximate equivalent taxable and tax-free yields
at the 1994 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.
 
  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.

                                THE DISTRIBUTOR
 
  Shares of the Fund are offered continuously through Van Kampen American
Capital Distributors, Inc., One Parkview Plaza, Oakbrook Terrace, Illinois
60181. Van Kampen American Capital Distributors, Inc. is a wholly-owned
subsidiary of Van Kampen American Capital, Inc., which is a subsidiary of VK/AC
Holding, Inc., a Delaware corporation that is controlled through an ownership of
a substantial majority of its common stock, by The Clayton & Dubilier Private
Equity Fund IV Limited Partnership ("C & D L.P."), a Connecticut limited
partnership. In addition, certain officers, directors and employees of Van
Kampen American Capital, Inc., and its subsidiaries own, in the aggregate not
more than 6% of the common stock of VK/AC Holding, Inc. and have the right to
acquire, upon the exercise of options, approximately an additional 10% of the
common stock of VK/AC Holding, Inc. C & D L.P. is managed by Clayton, Dubilier &
Rice, Inc. Clayton & Dubilier Associates IV Limited Partnership ("C & D
Associates L.P.") is the general partner of C & D L.P. 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.
 
                                      B-30
<PAGE>   522
 
  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 Investment
Company 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, 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 banks 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 banks 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 sub-trust, 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 period ended December 31, 1994, the Fund has recognized expenses under
the Plans of $7,646, $40,451, $45 for the Class A Shares, Class B Shares, and
Class C Shares, respectively, of which $4,306 and $6,313 represent payments to
financial intermediaries under the Selling Agreements for Class A Shares and
Class B Shares, respectively. For the period ended December 31, 1994, the Fund
has reimbursed the Distributor $0 and $185 for advertising expenses, and $1,233
and $1,077 for compensation of the Distributor's sales personnel for the Class A
Shares and Class B Shares, respectively.

                            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. Class B Shares redeemed during the first
seven years after their issuance and Class C Shares redeemed during the first
year after their
    
 
                                      B-31
<PAGE>   523
 
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. 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.

  The average annualized total return, including payment of the sales charge,

We conducted our audit in accordance with generally accepted

audit to obtain reasonable assurance about whether the financial state-
ments 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, 1994, 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 audit provides 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

Van Kampen Merritt Florida Insured Tax Free Income Fund
- --------------------------------------------------------------------------------

Notes to Financial Statements
December 31, 1994
- --------------------------------------------------------------------------------

1. Significant Accounting Policies
Van Kampen Merritt Florida Insured Tax Free Income Fund (the "Fund") was 
organized as a subtrust of the Van Kampen Merritt Tax Free Fund, a Massachusetts
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 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.


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 less than 60 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" and "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, 1994, 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.


D. Organizational Expenses and Initial Registration Costs-The Fund will 
reimburse Van Kampen American Capital Distributors, Inc. or its affiliates
("VKAC") for costs incurred in connection with the Fund's organization and
initial registration in the amount of $120,000. These costs are being amortized
on a straight line basis over the 60 month period ending July 29, 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 and initial registration
costs 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, 1994, the Fund had an accumulated capital loss 
carryforward for tax purposes of $41,580 which will expire on December 31, 2002.
Net realized gains or losses may differ for financial and tax reporting purposes
primarily as a result of post October 31 losses which are not recognized for tax
purposes until the first day of the following fiscal 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. 


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, counsel
to the Fund, of which a trustee of the Fund is an affiliated person.

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, 1994, VKAC owned 100 shares each of Classes A, B and C.


3. Capital Transactions
The Fund has outstanding three classes of common shares, Classes A, B and C. 
There are an unlimited number of shares of each class without par value 
authorized.

At December 31, 1994, paid in surplus aggregated $9,234,813, $11,212,650 and
$11,801 for Classes A, B and C, respectively. For the period ended December 31,
1994, transactions were as follows:

Class B and C shares are offered without a front end sales charge, but are
subject to a contingent deferred sales charge (CDSC). The CDSC will be imposed
on most redemptions made within six years of the purchase for Class B and one
year of the purchase for Class C as detailed in the following schedule. The
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.

For the period ended December 31, 1994, VKAC, as Distributor for the Fund, 
received net commissions on sales of the Fund's Class A shares of approximately
$2,000 and received CDSC on the redeemed shares of Classes B and C of 
approximately $20,200. Sales charges do not represent expenses of the Fund.


4. Investment Transactions
Aggregate purchases and cost of sales of investment securities, excluding 
short-term notes, for the year ended December 31, 1994, were $21,222,228 and
$2,536,245, 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 invest-

ments. Upon disposition, a realized gain or loss is recognized accordingly.
Summarized below are the specific types of derivative financial instruments used
by the Fund.


A. 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.

The fluctuation in market value of the contracts is settled daily through a cash
margin account. Realized gains and losses are recognized when the contracts are
closed or expire.

Transactions in futures contracts, each with a par value of $100,000, for the
period ended December 31, 1994, 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.


6. Distribution and Service Plans
The Fund and its shareholders have adopted a distribution plan (the 
"Distribution Plan") pursuant to Rule 12b-1 under the Investment Company Act of
1940 and a service plan (the "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 .30% each of Class A shares and 1.00% each
of Class B and Class C shares are accrued daily. Included in these fees for the
period ended December 31, 1994, are payments to VKAC of approximately $30,500.

    Van Kampen Merritt New Jersey Tax Free Income Fund (the "Fund") is a
non-diversified mutual fund, organized as a separate sub-trust of Van Kampen
Merritt Tax Free Fund. 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.

    The Fund currently offers three classes of its shares (the "Alternative
Sales Arrangements") 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 (i) at the time of purchase (the "Class A Shares") or (ii) on a
contingent deferred basis (Class A Share accounts over $1 million, "Class B
Shares" and "Class C Shares"). The Alternative Sales Arrangements permit an
investor to choose the method of purchasing shares that is more beneficial to

                               PROSPECTUS SUMMARY
- --------------------------------------------------------------------------------
 
   
  The following summary is qualified in its entirety by reference to the more
detailed information included elsewhere in this Prospectus and the Statement of
Additional Information.
    
 
THE FUND  Van Kampen Merritt New Jersey Tax Free Income Fund (the "Fund") is a
non-diversified mutual fund, organized as a separate sub-trust of Van Kampen
Merritt Tax Free Fund.
 
INVESTMENT OBJECTIVE AND POLICIES  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 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."
 
PURCHASING SHARES OF THE FUND  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 with respect to each class
is $1,000. 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 "Purchasing Shares of the Fund."
 
   
INVESTMENT ADVISER  Van Kampen American Capital Investment Advisory Corp. (the
"Adviser") is the investment adviser for the Fund. See "Investment Advisory
Services."
    
 
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
 
                                        4
<PAGE>   538
 
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."

(1) The Adviser agreed to waive a portion of its "Management Fees" during the
    Fund's last fiscal year. Absent the Adviser's waiver of its fee and
    assumption of a portion of the expenses of the Fund, the "Management Fees"
    would have been 0.60% for each class of shares, 12b-1 Fees would have been
    0.30% for Class A Shares and 1.00% each for Class B Shares and Class C
    Shares, and the "Total" would have been 3.17% for Class A Shares, 3.89% for
    Class B Shares and 3.85% 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. See "The
    Distribution and Service Plans."

You would pay the following expenses on a $1,000
  investment, assuming (i) an operating expense
  ratio of 0.17% for Class A Shares, 0.93% for
  Class B Shares and 0.91% for Class C Shares,
  (ii) 5% annual return and (iii) redemption at
  the end of each time period:
  Class A Shares.................................   $49      $53      $57     $  68
  Class B Shares.................................   $49      $65      $66     $  82
  Class C Shares.................................   $19      $29      $50     $ 112
An investor would pay the following expenses on
  the same $1,000 investment assuming no
  redemption at the end of each period:
  Class A Shares.................................   $49      $53      $57     $  68
  Class B Shares.................................   $ 9      $30      $51     $  82
  Class C Shares.................................   $ 9      $29      $50     $ 112
</TABLE>
    
 
  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 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 "Investment Advisory
Services" and "The Distribution and Service Plans."

THE FUND
- --------------------------------------------------------------------------------
 
  Van Kampen Merritt New Jersey Tax Free Income Fund (the "Fund") is a non-
diversified separate sub-trust of Van Kampen Merritt Tax Free Fund (the
"Trust"), an open-end management investment company, commonly known as a "mutual
fund," organized as a Massachusetts 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 "Investment Company Act").
The Fund is designed for investors who are residents of New Jersey for tax
purposes. 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 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
 
                                       10
<PAGE>   544
 
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 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
 
                                       11
<PAGE>   545
 
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 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
 
                                       12
<PAGE>   546
 
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 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,
 
                                       13
<PAGE>   547
 
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 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
 
                                       14
<PAGE>   548
 
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
 
                                       15
<PAGE>   549
 
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.
 
  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 high-grade municipal portfolio securities having an
aggregate value equal to the amount of
    
 
                                       16
<PAGE>   550
 
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 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
 
                                       17
<PAGE>   551
 
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 Investment Company Act. See
"Investment Policies and Restrictions" in the Statement of Additional
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
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
 
                                       18
<PAGE>   552
 
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% during the first quarter of 1989 to a recessionary
peak of 9.3% during 1992. Since then, the unemployment rate fell to 6.7% during
the fourth quarter of 1993. The jobless rate averaged 7.1% during the first nine
months of 1994, but this estimate is not comparable to those prior to January
because of major changes in the federal survey from which these statistics are
obtained.
 
  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 $59,000,000 State of New Jersey General Obligation
Bonds on November 23, 1994, which was the most recent issuance of this type of
bond, 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
 
                                       19
<PAGE>   553
 
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.

PURCHASING SHARES OF THE FUND
- --------------------------------------------------------------------------------
 
  The Fund currently offers three classes of shares to the public through Van
Kampen American Capital Distributors, Inc. (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 or eligible non-NASD members acting as brokers or agents
for investors ("brokers"). The Fund reserves the right to suspend or terminate
the public offering of its shares at any time and without prior notice.
 
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 fees with respect to each class of shares that may be incurred over
the anticipated duration of their investment in the Fund.
 
   
  The Fund currently 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
$1,000,000 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 $1,000.
The minimum subsequent investment with respect to each class of shares is $100.
It is presently the policy of the Distributor not to accept any order for Class
B Shares or Class C Shares in an amount of $1,000,000 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
 
                                       20
<PAGE>   554
 
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). Investors who intend to hold their
shares for a significantly long time may not wish to continue to bear the
ongoing distribution and service expenses of Class C Shares which, in the
aggregate, eventually would exceed the aggregate amount of the initial sales
charge and distribution and service related expenses applicable to Class A
Shares, irrespective of the fact that a CDSC would eventually not apply to a
redemption of such Class C Shares.
 
  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. Only the Class B Shares are subject to
a conversion feature (discussed below). Generally, a class of shares subject to
a higher ongoing distribution fee, service fee or, where applicable, the
conversion feature will have a higher expense ratio and pay lower dividends than
a class of shares subject to a lower ongoing distribution fee 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 "Net Asset Value."
 
  The administrative expenses that may be allocated to a specific class of
shares may consist of (i) transfer agency 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
 
                                       21
<PAGE>   555
 
identified that should be properly allocated to one or more classes of shares
that shall be approved by the SEC pursuant to an amended exemptive order. 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 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
securities 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. See "Net Asset
Value."
 
   
  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 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. 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. In addition, the Distributor may, from time to
time, sponsor sales contests with respect to sales of the Fund's Class A Shares
and Class B Shares pursuant to which brokers, dealers and financial
intermediaries may receive additional compensation of up to 2% of sales in such
shares. In connection therewith, the Distributor may consider combining the
sales of shares made by such brokers, dealers and financial intermediaries of
certain funds in The Van Kampen Merritt Family of Funds. In addition, the
Distributor may provide additional compensation to Edward D. Jones & Co. or an
affiliate thereof
    
 
                                       22
<PAGE>   556
 
   
based on a combination of its sales of shares and increases in assets under
management. In addition, the Distributor is sponsoring a sales contest for
INVEST Financial Corporation ("INVEST") relating to the Fund and other funds
distributed by the Distributor, pursuant to which the Distributor may provide an
INVEST broker an award valued up to $750.00 for sales of such funds during the
period April 1, 1995, through May 31, 1995. Such payments are made by the
Distributor out of its own assets, and not out of the assets of the Fund. These
programs will not change the price an investor pays for shares or the amount
that the Fund will receive from such sale.
    
 
INITIAL SALES CHARGE ALTERNATIVE--CLASS A SHARES
 
  The public offering price of Class A Shares for purchasers choosing the
initial sales charge alternative 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 an 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.

* No sales charge is payable at the time of purchase on investments of
  $1,000,000 or more, although for such investments the Fund imposes a
  contingent deferred sales charge 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 million, plus 0.20% on the next $2 million and
  0.08% on the excess over $5 million. See "Purchasing Shares Of The Fund --
  Deferred Sales Charge Alternatives" for additional information with respect to
  contingent deferred sales charges.
    
 
  QUANTITY DISCOUNTS. Purchasers of Class A Shares may be entitled to reduced
initial sales charges through a combination of investments, rights of
accumulation or a Letter of Intent (even if an investor is not making an
investment of a size that normally would qualify for a quantity discount).
Investors, or their broker, dealer or financial intermediary,
 
                                       23
<PAGE>   557
 
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.
 
  For purposes of determining whether a purchase qualifies for a reduced initial
sales charge, the term "any person" is defined as any one of the following:
 
     (i) an individual, their spouse and children under the age of 21, trust or
         custodial accounts established for any of their sole benefit(s) and any
         corporation, partnership or sole proprietorship which is 100% owned,
         either alone or in combination, by any of the foregoing; or
 
    (ii) a trustee or other fiduciary purchasing for a single trust estate
         (including a pension, profit-sharing or other employee benefit trust
         created pursuant to a plan qualified under Section 401 of the Internal
         Revenue Code, as amended); or
 
   (iii) a "company" as defined in Section 2(a)(8) of the Investment Company
         Act.
 
  1. Combination of Investments. Purchases of Class A Shares of the Fund, or
shares of other Van Kampen Merritt funds distributed by the Distributor subject
to an initial sales charge ("ISC Shares"), which are made at any one time by
"any person" may be combined to receive a quantity discount.
 
  2. Rights of Accumulation. Under the rights of accumulation, in determining
the sales charge to be paid for a current purchase of Class A Shares, "any
person" may combine their current purchase with the current public offering
price of Class A Shares of the Fund or ISC Shares, which are owned by such
person. If the account an investor is combining for rights of accumulation
differs from the account into which the investor's current purchase is placed,
the investor must indicate to the Transfer Agent the account number (and, if
applicable, fund name) of such other account.
 
  3. Letter of Intent. Purchasers of Class A Shares may qualify immediately for
a reduced sales charge by stating their intention to purchase an amount of Class
A Shares, during a 13 month period, that would qualify the investor for a
reduced sales charge. An investor may do this by signing a nonbinding Letter of
Intent, which may be signed at any time within 90 days after the first
investment to be included under the Letter of Intent. Class A Shares purchased
under the "Rights of Accumulation" described above (including investments in ISC
Shares) may be, at the time of the signing of the Letter of Intent, applied
towards completion of an investor's Letter of Intent. In addition, if an
investor's broker, dealer or financial intermediary and the Distributor agree to
refund the appropriate portion of their respective concessions to the Fund, the
sales charge on an investor's previous purchases made within 90 days may be
adjusted to the reduced sales charge under the Letter of Intent, and the
refunded concession will be used to purchase shares of the Fund at the public
offering price next determined after receipt of such monies. Each investment
made after signing the Letter of Intent will be entitled to the initial sales
 
                                       24
<PAGE>   558
 
charge applicable to the total investment indicated in the Letter of Intent. If
an investor does not complete the necessary purchases under the Letter of Intent
within 13 months from the date of the first purchase included thereunder, the
sales charge will be adjusted upward, corresponding to the amount actually
purchased.
 
  When an investor signs a Letter of Intent, Class A Shares of the Fund
purchased with a value of 5% of the amount specified in the Letter of Intent
will be restricted; that is, these Class A Shares cannot be sold or redeemed
until the Letter of Intent is satisfied or the additional sales charges have
been paid. If the total purchases made under the Letter of Intent, less
redemptions, equal or exceed the amount specified in the Letter of Intent, these
Class A Shares will no longer be restricted. If the total purchases, less
redemptions, exceed the amount so specified, and qualify an investor for a
further quantity discount, the Distributor and the investor's securities broker,
dealer or financial intermediary will, upon request, remit their respective
portions of the sales concession and with that amount, purchase additional Class
A Shares of the Fund for the investor's account at the next determined public
offering price. If an investor does not complete the necessary purchases under
the Letter of Intent, the sales charges will be adjusted upward and if, after
written notice, the investor does not pay the increased sales charge, sufficient
restricted Class A Shares will be redeemed to pay such charge.
 
  OTHER PURCHASE PROGRAMS. Purchasers of Class A Shares may be entitled to
reduced initial sales charges in connection with unit 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.
 
  1. Unit Trust Reinvestment Programs. The Fund permits unitholders of New
Jersey unit investment trusts to reinvest distributions from such trusts in
Class A Shares of the Fund at net asset value.
 
  The Fund also permits unitholders of other unit investment trusts to reinvest
their distributions in Class A Shares of the Fund and other ISC Shares with no
minimum initial or subsequent investment requirement, and with a lower sales
charge 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 such 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 dealer or broker, 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 securities broker or dealer
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 the Fund's transfer agent with
appropriate backup data for each
 
                                       25
<PAGE>   559
 
participating investor in a computerized format fully compatible with the
transfer agent's 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.
    
 
2. NAV Purchase Options
 
  The classes of investors entitled to purchase shares of the Fund at net asset
value are as follows:
 
 (a) Current or retired Trustees/Directors of funds advised by Van Kampen
     American Capital Investment Advisory Corp., Van Kampen American Capital
     Asset Management, Inc. or John Govett & Co. Limited and such persons'
     families and their beneficial accounts. The term "families" includes a
     person's spouse, children and grandchildren, parents, and a person's
     spouse's parents.
 
 (b) Current or retired directors, officers and employees of VK/AC Holdings,
     Inc. and any of its subsidiaries, Clayton, Dubilier & Rice, Inc., employees
     of an investment subadviser to any such fund or an affiliate of such
     subadviser; and such persons' families and their beneficial accounts.
 
 (c) Directors, officers, employees and registered representatives of financial
     institutions that have a selling agreement with the Distributor and their
     spouses and minor children 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.
 
   
 (d) 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 the Fund alone, or in any combination of
     Class A Shares of the Fund and ISC Shares of other funds distributed by the
     Distributor as described herein under "Purchasing Shares Of The Fund --
     Initial Sales Charge Alternative -- Quantity Discounts," during the 13
     month period commencing with the first investment pursuant hereto equals at
     least $1 million. The Distributor may pay such entities through which
     purchases are made an amount up to 0.50% of the amount invested, over a
     twelve month period following such transaction.
    
 
 (e) Trustees and other fiduciaries purchasing shares for retirement plans of
     organizations with retirement plan assets of $10 million or more. The
     Distributor may pay commissions of up to 1% for such purchases.
 
 (f) Accounts as to which a selling firm charges an account management fee
     ("wrap accounts"), provided the selling firm has executed a supplemental
     agreement to their existing selling agreement with the Distributor.
 
                                       26
<PAGE>   560
 
 (g) 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.
 
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 other financial
intermediaries which percentage rate will be equal to (i) 1.00% with respect to
Class A Shares in an amount of $1 million or more; (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. Sales compensation with
respect to Class A Shares subject to a CDSC is set forth under "Purchasing
Shares Of The Fund -- Initial Sales Charge Alternative."
 
  CDSC Shares redeemed within a specified period of time generally will be
subject to a contingent deferred sales charge at the rates set forth below. The
amount of the contingent deferred sales charge 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 contingent
deferred sales charge 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 contingent deferred sales charge 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 contingent deferred sales charge
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. Investors
should understand that the purpose of the contingent deferred sales
 
                                       27
<PAGE>   561
 
charge and the distribution fee with respect to a class of CDSC Shares is the
same as the initial sales charge and the distribution fee with respect to Class
A Shares.
 
  In determining whether a contingent deferred sales charge 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 contingent deferred sales charge 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, if any, and fourth of CDSC Shares held
longest during the period of time that a contingent deferred sales charge 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).
 
  The contingent deferred sales charge is waived (i) on a redemption of shares
following the death of a shareholder, or (ii) to the extent that the redemption
represents a minimum required distribution from an IRA or other retirement plan
to a shareholder who has attained the age of 70 1/2.
 
   
  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 $1,000,000 or more,
although for such investments the Fund imposes a contingent deferred sales
charge 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 million, plus 0.20% on the next $2 million and 0.08% on the
excess over $5 million.

  CLASS B SHARES. Class B Shares redeemed within seven years of purchase
generally will be subject to a contingent deferred sales charge at the rates set
forth below, charged as a percentage of the dollar amount subject thereto:

  The contingent deferred sales charge generally is waived on redemptions of
Class B Shares made pursuant to the Systematic Withdrawal Program. See
"Shareholder Programs -- Systematic Withdrawal Program."
 
  CLASS C SHARES. Class C Shares redeemed within the first twelve months of
purchase generally will be subject to a contingent deferred sales charge 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. Seven years after the end of the month in which a
shareholder's order to purchase a Class B Share of the Fund was accepted, such
Class B Share automatically will convert to a Class A Share and will no longer
be subject to the higher aggregate distribution and service fees. The purpose of
the conversion feature is to relieve the holders of Class B Shares that have
been outstanding for a period of time sufficient for the Distributor to have
been compensated for distribution expenses related to the Class B Shares from
most of the burden of such distribution-related expenses. The Fund does not
expect to issue any stock certificates upon conversion.
 
  For purposes of conversion of Class A Shares, Class B Shares purchased through
the reinvestment of dividends and distributions paid in respect of Class B
Shares in a shareholder's account will be considered to be held in a separate
sub-account. Each time any Class B Shares in the shareholder's account (other
than those in the sub-account) convert to Class A Shares, an equal pro rata
portion of the Class B Shares in the sub-account also will convert to Class A
Shares. The holding period applicable to a Class B Share acquired through the
use of the exchange privilege (discussed below) shall be the holding period
applicable to a Class B Share of such Fund acquired other than through use of
the exchange privilege. For purposes of calculating the holding period
applicable to a Class B Share of the Fund prior to conversion, a Class B Share
of the Fund issued in connection with an exercise of the exchange privilege, or
a series of exchanges, shall be deemed to have been issued on the date on which
the investor's order to purchase the
 
                                       29
<PAGE>   563
 
exchanged Class B Share was accepted or, in the case of a series of exchanges,
when the investor's order to purchase the original Class B Share was accepted.
 
  The conversion of Class B 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 services fee and transfer agency costs
with respect to Class B 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 Class B
Shares does not constitute a taxable event under federal income tax law. The
conversion of Class B Shares to Class A Shares may be suspended if such an
opinion is no longer available. In that event, no further conversions of Class B
Shares would occur, and Class B Shares might continue to be subject to the
higher aggregate distribution and service fees for an indefinite period.
 
- --------------------------------------------------------------------------------
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 the Fund's transfer agent receives payments for such shares.
However, shares become entitled to dividends on the day the Fund's transfer
agent 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 information under the "Distributions" section of the
Account Application bound in this Prospectus or available from State Street Bank
and Trust Company, c/o National Financial Data Services, Van Kampen Merritt
Funds, P.O. Box 419001, Kansas City, MO 64141-6001 (the "Transfer Agent"). After
the Transfer Agent receives
 
                                       30
<PAGE>   564
 
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 to the Transfer Agent. This election may be made by telephone by
calling 1-800-341-2911 or in writing to the Transfer Agent. For inquiries
through Telecommunications Device for the Deaf (TDD), dial 1-800-772-8889,
during the hours of 7:30 a.m. and 4:00 p.m. Central Standard Time. If a
shareholder elects to change the method of distribution, such change will be
effective only with regard to distributions for which the record date is seven
or more business days after the Transfer Agent has received the request. CDSC
Shares received as reinvested dividends are subject to a 12b-1 fee, a portion of
which may indirectly pay for the initial sales commission incurred on behalf of
the investor.
- --------------------------------------------------------------------------------
REDEMPTION OF SHARES
- --------------------------------------------------------------------------------
 
  WRITTEN REDEMPTION REQUEST. Shareholders may sell shares without charge (other
than, with respect to the CDSC Shares, any applicable contingent deferred sales
charge) at any time by mailing a written redemption request in proper form to
the Transfer Agent. This request should be sent to State Street Bank and Trust
Company, c/o National Financial Data Services, Van Kampen Merritt Funds, P.O.
Box 419001, Kansas City, MO 64141-6001. The request should indicate the number
of shares to be redeemed of a particular fund and the class designations of such
shares, identify the account number and be signed exactly as the shares are
registered. If the amount being redeemed is in excess of $50,000 or if the
redemption proceeds will be sent to an address other than the address of record,
the signature(s) must be guaranteed by a member firm of a principal stock
exchange, a commercial bank or trust company which is a member of the Federal
Deposit Insurance Corporation, a credit union or a savings association. The
guarantee must state the words "Signature Guaranteed" along with the name of the
granting institution. Shareholders should verify with the institution that it is
an eligible guarantor prior to signing. A guarantee from a notary public is not
acceptable. If certificates are held for the shares being redeemed, such
certificates must be sent and endorsed for transfer or accompanied by an
endorsed stock power. Share certificates should be sent by registered mail to
National Financial Data Services, 1004 Baltimore Avenue, Dwight Building, Sixth
Floor, Kansas City, MO 64105-1807. Shareholders will receive the net asset value
per share next computed after the Transfer Agent receives the redemption request
and certificates (if any) in proper form. Any applicable contingent deferred
sales charge with respect to CDSC Shares redeemed will be deducted from the
redemption proceeds prior to transmittal of such proceeds to the shareholder.
 
   
  TELEPHONE REDEMPTIONS. Shareholders may sell shares by calling the Fund at
1-800-341-2911 before 3:00 p.m. Central Standard Time to request a redemption by
the Fund. For inquiries through Telecommunications Device for the Deaf (TDD),
dial 1-800-772-8889, during the hours of 7:30 a.m. to 3:00 p.m. Central Standard
Time. There is a
    
 
                                       31
<PAGE>   565
 
$500 minimum and a $1,000,000 maximum per request if the redemption proceeds are
to be mailed to the shareholder. If the redemption proceeds are to be wired to a
bank there is a minimum of $5,000 and a $1,000,000 maximum per request. Prior to
redeeming shares by telephone the "Expedited Telephone Redemption" section of
either the Account Application or Expedited Telephone Redemption and Exchange
Request Form (the "Authorization") must be completed and on file with the
Transfer Agent. The signature(s) on the Authorization must be guaranteed by a
member firm of a principal stock exchange, a commercial bank or trust company
which is a member of the Federal Deposit Insurance Corporation, a credit union
or a savings association unless the Authorization is completed at the time an
account is originally established. The guarantee must state the words "Signature
Guaranteed" along with the name of the granting institution. Shareholders should
verify with the institution that it is an eligible guarantor prior to signing. A
guarantee from a notary public is not acceptable. A redemption requested by
telephone will be processed at the net asset value next determined after receipt
of the request. Any applicable contingent deferred sales charge with respect to
CDSC Shares redeemed will be deducted from the redemption proceeds prior to
transmittal of such proceeds to the shareholder. The proceeds would then be made
payable to the registered shareowner(s) and mailed to the address registered on
the account or wired to a bank, as requested on the Authorizations. Shareholders
cannot redeem shares by telephone if stock certificates are held for those
shares. This service is not available with respect to shares held in an
Individual Retirement Account for which State Street Bank and Trust Company acts
as custodian. In addition, this service is not available with respect to shares
purchased by check until 15 days after purchase.
 
   
  By establishing the telephone redemption service, a shareholder authorizes the
Fund or the Transfer Agent to act upon the instructions of any person by
telephone to redeem shares for any account for which such service has been
authorized. The Fund, the Distributor, the Transfer Agent and National Financial
Data Services, Inc. ("NFDS") employ procedures reasonably believed to confirm
that instructions communicated by telephone are genuine. Such procedures include
requiring a person attempting to redeem shares by telephone to provide, on a
recorded line, the name on the account, a social security number or tax
identification number and such additional information as may be included in the
Authorization. In addition, a shareholder agrees that none of the Fund, the
Distributor, the Transfer Agent or National Financial Data Services will be
liable for any loss, liability, cost or expense arising out of any request,
including any fraudulent or unauthorized request. This service may be amended or
terminated at any time by the Transfer Agent or the Fund. If a shareholder is
unable to reach the Fund by telephone, he or she may redeem shares pursuant to
the procedures set forth above under the caption "Written Redemption Request."
During periods of extreme economic or market changes, it may be difficult for
investors to reach the Fund by telephone and to effect telephone redemptions.
    
 
  REDEMPTION THROUGH DEALERS. Shareholders may sell shares (whether in
certificate or book-entry form) through their securities dealer, who will
telephone the request to the Distributor. Shareholders will receive the net
asset value next determined after such shareholder places the sell order. Any
applicable contingent deferred sales charge with
 
                                       32
<PAGE>   566
 
respect to CDSC Shares redeemed will be deducted from the redemption proceeds
prior to transmittal of such proceeds to the shareholder. It is the
responsibility of the shareholder's broker, dealer or financial intermediary to
transmit the redemption order to the Distributor. Because the Fund generally
will determine net asset value once each business day as of the close of
business, sell orders placed through a shareholder'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 shareholder's order
to be fulfilled on the basis of the net asset value to be determined that day.
Any change in the redemption price due to the failure of the Distributor to
receive a sell order prior to such time must be settled between the shareholder
and the broker, dealer or financial intermediary submitting the order. The Fund
does not charge for this transaction (other than any applicable contingent
deferred sales charge). Shareholders must submit a written redemption request in
proper form to their securities dealer within five business days after calling
the dealer with the sell order. The request should indicate the number of shares
to be redeemed and the class designation of such shares, identify the account
number and the order or confirmation number assigned to the trade and be signed
by the shareholder exactly as the shares are registered. If the amount of the
redemption exceeds $50,000 or if the redemption proceeds will be sent to an
address other than the address of record, signature(s) must be guaranteed by a
member firm of a principal stock exchange, a commercial bank or trust company
which is a member of the Federal Deposit Insurance Corporation, a credit union
or a savings association. The guarantee must state the words "Signature
Guaranteed" along with the name of the granting institution. Shareholders should
verify with the institution that it is an eligible guarantor prior to signing. A
guarantee from a notary public is not acceptable. If certificates are held for
the shares being redeemed, such certificates must be sent endorsed for transfer
or accompanied by an endorsed stock power. Certificates should be sent by
registered mail to State Street Bank and Trust Company, c/o National Financial
Data Services, Van Kampen Merritt Funds, 1004 Baltimore Avenue, Dwight Building,
Sixth Floor, Kansas City, MO 64105-1807. Shareholders whose shares are held in
an Individual Retirement Account ("IRA") for which State Street Bank and Trust
Company acts as custodian may not sell their shares through their securities
dealers.
 
   
  REDEMPTION UPON DISABILITY. The Fund will waive the CDSC on Class B Share
redemptions following the disability of a Class B shareholder. An individual
will be considered disabled for this purpose if he or she meets the definitions
thereof in Section 72(m)(7) of the Internal Revenue Code (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 Fund will
require satisfactory proof of disability before it determines to waive the CDSC
on Class B Shares.
    
 
   
  In cases of disability, the CDSC on Class B Shares will be waived where the
disabled person is either an individual shareholder or owns the shares as a
joint tenant with right of
    
 
                                       33
<PAGE>   567
 
   
survivorship or is the beneficial owner of a custodial or fiduciary account, and
where the redemption is made within one year of the death or initial
determination of disability. This waiver of the CDSC on Class B 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. Whether shares are redeemed by the Fund or sold through a securities
dealer, a check for the proceeds (net of any required tax withholding and, with
respect to CDSC Shares, any applicable contingent deferred sales charge)
ordinarily will be mailed to shareholders or their dealer, as the case may be,
within seven calendar days after a redemption request or repurchase order and
share certificates (if any) are received in proper form as set forth above. Wire
transfers from the Fund of redemption proceeds, in the manner described above,
ordinarily will be transmitted to the shareholder within one business day. If
any shares are redeemed or repurchased shortly after purchase, the Fund will not
mail the proceeds until checks received for the purchase of shares have cleared,
which may take 10 days or more. The proceeds, of course, may be more or less
than the cost of the shares.
 
  The right of redemption or resale to the Fund may be suspended or the date of
payment postponed during any period when the New York Stock Exchange is closed
(other than customary weekend and holiday closings), when an emergency exists as
defined by rules and regulations of the SEC, or during any period when the SEC
has by order permitted such suspension or postponement.
 
  The Fund reserves the right to redeem any investment if the value of an
account falls below $500. Before the Fund makes such redemption it will provide
the shareholder with written notice and 30 days in which to make an additional
investment sufficient to increase the value of the account to at least $500.
 
- --------------------------------------------------------------------------------
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.
 
                                       34
<PAGE>   568
 
  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 sub-trust. 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.

  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 sub-trust. Subject to their authority, the Adviser and the respective

                                       35
<PAGE>   569
 
determine to waive temporarily all or a portion of its fee or it may discontinue

  Under its investment advisory agreement, 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 Investment Company Act, of the Adviser, Van Kampen American
Capital Distributors, Inc. or Van Kampen American Capital, Inc.), the charges
and expenses of independent accountants, legal counsel, any transfer 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
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 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 trustees/directors, officers and employees to buy and sell
securities for their personal accounts subject to preclearance and other
procedures designed to prevent conflicts of interest.
 
   
  PORTFOLIO MANAGEMENT.  David C. Johnson, a First 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 for the last five years. William V.
Grady, a Vice President of the Adviser, is primarily responsible for the
day-to-day management of the Fund's portfolio. Mr. Grady has been employed by
the Adviser since 1992. Prior to 1992, Mr. Grady was associated with Municipal
Bond Investors Assurance Corporation, and prior to 1990, Mr. Grady was
associated with Cigna Investments, Inc.
    
- --------------------------------------------------------------------------------
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
 
                                       36
<PAGE>   570
 
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,
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.
 
- --------------------------------------------------------------------------------
THE 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 Investment
Company 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,
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, NASD
members or eligible non-members who are acting as brokers or agents and similar
agreements between the Fund and banks who are acting as brokers (collectively,
"Selling Agreements") that may provide for their customers or clients certain
services or assistance. Brokers, dealers and banks that have entered into
Selling Agreements with the Distributor and sell shares of the Fund are referred
to herein as "financial intermediaries."
 
  CLASS A SHARES. The Fund may spend an aggregate amount up to 0.30% 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
 
                                       37
<PAGE>   571
 
to the Service Plan in connection with the ongoing provision of services to
holders of such shares by the Distributor and by financial intermediaries and in
connection with the maintenance of such shareholders' accounts. The Fund pays
the Distributor the lesser of the balance of the 0.30% not paid to such
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 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 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
financial intermediary's customers. The Fund pays the Distributor the lesser of
the balance of 0.75% not paid to such 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 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 contingent deferred sales charge. 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
 
                                       38
<PAGE>   572
 
   
such CDSC Share may be deemed to incur expenses attributable to other
shareholders of such class. The Fund will disclose in its prospectus from time
to time the then current amount of any such unreimbursed expenses with respect
to each class of CDSC Shares expressed as a dollar amount and as a percent of
the Fund's total net assets. As of December 31, 1994, there were $9,717 and
$2,159 of unreimbursed distribution related expenses with respect to Class B
Shares and Class C Shares, respectively, representing 0.10% and 0.02% of the
Fund's total net assets. 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
contingent deferred sales charges.
    
 
  Because the Fund is a sub-trust of the Trust, amounts paid to the Distributor
as reimbursement for expenses of one sub-trust of the Trust may indirectly
benefit the other funds which are sub-trusts 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 contingent deferred sales charge
applicable to a particular class of CDSC Shares to defray distribution related
expenses attributable to any other class of CDSC 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.

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, and reflects applicable New Jersey tax laws as of the date hereof.
 
  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."
 
  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
 
                                       39
<PAGE>   573
 
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.
 
  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.
 
                                       40
<PAGE>   574
 
   
  New Jersey S corporations that are shareholders of the Fund generally will be
subject to the Corporation Business Tax at a rate of 2.42% of their entire net
income. 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, and reflects applicable federal tax laws as of the
date of this Prospectus.
 
  The Fund intends to qualify each year and to elect to be treated as a
regulated investment company under Subchapter M of the Internal Revenue Code of
1986, as amended (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 gains, but not net capital gain, which is the
excess of net 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 net
investment 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. Similarly, the Fund will not be subject to federal
income tax on any net capital gain distributed to its shareholders. As a
sub-trust of a Massachusetts business trust, the Fund will not be subject to any
excise or income taxes in Massachusetts as long as it qualifies as a regulated
investment company for federal income tax purposes.
 
  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 (which does not
include tax-exempt income) for such year and at least 98% of its capital gain
net income (the latter of which is generally computed on the basis of the
one-year period ending on October 31 of such year), plus any required
distribution 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 was
distributed to its shareholders) and all distributions out of earnings and
profits would be taxed to shareholders as
 
                                       41
<PAGE>   575
 
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 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 closed out), 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.
 
  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 avoid income and excise taxes, the Fund may have to
dispose of securities that it would otherwise have continued to hold.
 
  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 gross income be derived from the disposition of securities
held for less than three months.
 
  DISTRIBUTIONS. If the Fund qualifies as a regulated investment company and
satisfies the 90% distribution requirement, and if, at the close of each quarter
of the Fund's taxable year, at least 50% of the total value of the Fund's assets
consists of obligations the interest on which is exempt from federal income tax
("tax-exempt obligations"), the Fund will be qualified to pay exempt-interest
dividends to its shareholders to the extent of its tax-exempt interest income
(less expenses applicable thereto). Exempt-interest dividends are excludable
from a shareholder's gross income for federal income tax purposes, but may be
taxable distributions for state, local and other tax purposes. Exempt-interest
dividends are included, however, 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. Interest expense with respect to
indebtedness incurred or continued by a shareholder
 
                                       42
<PAGE>   576
 
to purchase or carry shares of the Fund is not deductible to the extent that
such interest relates to exempt-interest dividends received from the Fund.
 
  Distributions of the Fund's investment company taxable income (which does not
include tax-exempt interest income) are taxable to shareholders as ordinary
income whether received in shares or in cash. Shareholders who receive
distributions in the form of additional shares will have a basis for federal
income tax purposes in each such share equal to the value thereof on the
reinvestment date. Distributions of the Fund's net capital gain ("capital gain
dividends"), if any, are taxable to shareholders at the rates applicable to
long-term capital gains regardless of the length of time shares of the Fund have
been held by such shareholders. All or a portion of the Fund's gain from the
sale or redemption of tax-exempt obligations purchased at a market discount will
be treated as ordinary income rather than capital gain. 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 shareholders (assuming such shares are held as
a capital asset). It is not expected that any portion of the distributions from
the Fund will be eligible for the dividends received deduction for corporations.
The Fund will inform shareholders of the source and tax status of distributions
promptly after the close of each calendar year.
 
  Exempt-interest dividends allocable to interest received by the Fund on
certain "private activity" obligations issued after August 7, 1986 will be
treated as interest on such obligations and thus will give rise to an item of
tax preference that will increase a shareholder's alternative minimum taxable
income. In addition, for corporations, alternative minimum taxable income will
be increased by a percentage of the amount by which a measure of income that
includes interest on tax-exempt obligations exceeds the amount otherwise
determined to be the alternative minimum taxable income. Accordingly, investment
in the Fund may cause such shareholders to be subject to (or result in an
increased liability under) the alternative minimum tax.
 
  Exempt-interest dividends will not be tax-exempt to the extent made to any
shareholder who is a "substantial user" of the facilities financed by tax-exempt
obligations held by the Fund or "related persons" of such substantial users.
 
  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 a month and paid in 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 is actually made.
 
  The Fund is required, in certain circumstances, to withhold 31% of taxable
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 individu-
 
                                       43
<PAGE>   577
 
als, their social security number) and certain required certifications or who
are otherwise subject to backup withholding.
 
  SALE OF SHARES. Redemption or sale of shares of the Fund will be a taxable
transaction for federal income tax purposes. Redeeming shareholders will
generally recognize gain or loss in an amount equal to the difference between
their basis in such redeemed shares of the Fund 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 generally be long-term if such shares have been held for more than
one year. Any loss realized on a taxable disposition of shares held for six
months or less will be disallowed to the extent of any exempt-interest dividends
received with respect to such shares. If such loss is not entirely disallowed,
it will be treated as a long-term capital loss to the extent of any capital gain
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 New Jersey and federal income tax discussions set forth above are
for general information only. Prospective investors should consult their tax
advisers regarding the specific New Jersey and federal tax consequences of
holding and disposing of shares, as well as the effects of other state, local
and foreign tax laws and any proposed tax law changes.
- --------------------------------------------------------------------------------
SHAREHOLDER PROGRAMS
- --------------------------------------------------------------------------------
 
   
  SHARE CERTIFICATES.  As a rule, the Fund will not issue share certificates.
Upon written or telephone request to the Fund, however, 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. In addition, if such certificates are lost the shareholder must
write to State Street Bank and Trust Company, c/o National Financial Data
Services, P.O. Box 419001, Kansas City, MO 64141-6001, Attn: Van Kampen Merritt
Funds, requesting an "affidavit of loss" and to obtain a Surety Bond in a form
acceptable to the Transfer Agent. On the date the letter is received the
Transfer Agent will calculate no more than 2.00% of the net asset value of the
issued shares, and bill the party to whom the certificate was mailed.
    
 
   
  SYSTEMATIC WITHDRAWAL PROGRAM.  If a shareholder's Class A Share account or
Class B Share account is valued at $10,000 or more, such shareholder's dividends
are being reinvested, a requested dollar amount may be paid from such account to
any person monthly, quarterly, semiannually or annually. The minimum amount that
may be withdrawn each period is $50; withdrawals will be made on the seventh
business day of the month in which they are scheduled to occur. Depending upon
the size of the payments requested and the fluctuations in the net asset value
of the shares redeemed, redemptions for the purpose of making such payments may
reduce or even exhaust the amounts in such account. If an investor acquires
additional shares of the Fund after joining the Systematic Withdrawal Program,
the investor must inform the Fund if he or she wants the new shares
    
 
                                       44
<PAGE>   578
 
to be subject to the Systematic Withdrawal Program by telephoning the Fund at
1-800-341-2911.
 
   
  With respect to redemptions of Class B Shares made pursuant to the Systematic
Withdrawal Program, an investor may annually redeem up to 12% of the net asset
value of the investor's initial investment in Class B Shares or, if the investor
does not join the program on the date of his or her initial investment, the net
asset value of the investor's Class B Shares on the date the investor elects to
participate in the Systematic Withdrawal Program. The Fund will waive the
contingent deferred sales charge applicable to Class B Shares redeemed pursuant
to the Fund's Systematic Withdrawal Program.
    
 
  It will ordinarily be disadvantageous to purchase shares (except through
reinvestment of distributions) while participating in a systematic withdrawal
program because a shareholder will be paying a sales charge, or will become
subject to a contingent deferred sales charge, in order to purchase shares at
the same time that shares are being redeemed upon which a sales charge may
already have been paid. Therefore, the Fund will not knowingly permit a
shareholder to make additional investments in shares of less than $5,000 if at
the same time such shareholder is making systematic withdrawals at a rate
greater than the distribution being paid on such shareholder's shares. The Fund
reserves the right to amend or terminate the systematic withdrawal program on
thirty days' notice, and a shareholder may withdraw from the program at any
time.
 
  EXCHANGE PRIVILEGE. Any Class A Shares of the Fund which have been registered
in a shareholder's name for at least 15 days will be able to be exchanged for
ISC Shares of other Van Kampen Merritt mutual funds distributed by the
Distributor that offer an exchange privilege. Under the exchange privilege, the
Fund will offer to exchange its Class A Shares for ISC Shares on the basis of
relative net asset value per share. Any ISC Shares exchanged into the Fund that
have been charged a sales load lower than the sales load applicable to Class A
Shares of the Fund will be charged the applicable sales load differential upon
exchange. ISC Shares of the Van Kampen Merritt Money Market Fund and Van Kampen
Merritt Tax Free Money Fund which have not previously been charged a sales load
(except for shares purchased via the reinvestment option) will be charged the
applicable sales load upon exchange into the Fund.
 
  Class B Shareholders of the Fund may exchange their Class B Shares
("Outstanding Class B Shares") for Class B Shares of other Van Kampen Merritt
mutual funds sponsored by the Distributor ("New Class B Shares") on the basis of
relative net asset value per Class B Share, without the payment of any
contingent deferred sales charge that might otherwise be due on redemption of
the Outstanding Class B Shares. Class B Shares of a fund acquired through use of
the exchange privilege will be 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.
 
  Class C Shares of the Fund are exchangeable for Class C Shares of other Van
Kampen Merritt mutual funds distributed by the Distributor on the same terms set
forth in the preceding paragraph with respect to Class B Shares, except that
Class C Shares do not convert to Class A Shares. The exchange privilege with
respect to any Van Kampen
 
                                       45
<PAGE>   579
 
   
Merritt money market fund sponsored by the Distributor is not available for
Class C Shareholders.
    
 
   
  In order to qualify for the exchange privilege, it is required that the shares
being exchanged have a net asset value of at least $1,000 (unless prior approval
has been obtained from the Fund). Shareholders will be able to effect an
exchange by telephone by calling the Fund at 1-800-341-2911 prior to 3:00 p.m.
Central Standard Time. For inquiries through Telecommunications Device for the
Deaf (TDD), dial 1-800-772-8889, during the hours of 7:30 a.m. and 3:00 p.m.
Central Standard Time. The exchange will be processed at the net asset value
next determined after receipt of such request. By utilizing the telephone
exchange service, a shareholder authorizes the Fund or the Transfer Agent to act
upon the instructions of any person by telephone to exchange shares from any
account for which such service has been authorized to any identically registered
account(s) with any Van Kampen Merritt fund distributed by the Distributor that
offers an exchange privilege. In addition, a shareholder agrees that none of the
Fund, the Distributor, the Transfer Agent or National Financial Data Services
("NFDS") will be liable for any loss, liability, cost or expense arising out of
any request, including any fraudulent request. The staff of the SEC currently is
reviewing its position with respect to such agreements. This service may be
amended or terminated at any time by the Transfer Agent or the Fund. If a
shareholder has certificates for any shares being exchanged, such certificates
must be surrendered prior to the exchange in the same manner as in redemption of
such shares. See "Redemption of Shares--Telephone Redemptions". Any shares
exchanged between the Fund and any of the other funds will begin earning
dividends on the next business day after the exchange is effected. 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.
    
 
  An exchange between Van Kampen Merritt funds pursuant to the exchange
privilege is treated as a sale for federal income tax purposes and, depending
upon the circumstances, a short- or long-term capital gain or loss may be
realized.
 
  The exchange privilege may be modified or terminated at any time, subject to
the requirement that the Fund give prominent notice thereof at least 60 days
prior to the effective date of the modification or termination in certain
circumstances. The Fund reserves the right to limit the number of times a
shareholder may exercise the exchange privilege.
 
  AUTOMATED MULTIPLE ACCOUNT SHAREHOLDER SERVICES (AMASSSM).
 
   
  1. 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
    
 
                                       46
<PAGE>   580
 
into which redemptions are to be deposited together with the completed
application. Once the Transfer Agent 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 the Transfer Agent.
 
  2. Automated Dividend Programs. The Fund will, upon the election of a
shareholder, automatically invest distributions from a shareholder's account
directly into a shareholder's bank account.
 
   
  3. Dividend Diversification. Monthly distributions and any net long-term
capital gain distributions to a shareholder's account may be invested in the
same class of shares of any other Van Kampen Merritt mutual fund distributed by
the Distributor at the then current net asset value, WITHOUT A SALES CHARGE,
upon election by a shareholder. This election may be made on the account
application bound in this Prospectus, by written notice to the Transfer Agent or
by calling the Fund directly at 1-800-341-2911, during the hours of 7:00 a.m. to
7:00 p.m. Central Standard Time. For inquiries through Telecommunications Device
for the Deaf (TDD), dial 1-800-772-8889. In order to qualify for this privilege,
a shareholder must have established an account in the other mutual fund prior to
electing this privilege. This privilege may be modified or terminated by the
Fund at any time.
    
 
  4. Easy Account Savings Enhancement Plan (EASE(SM)).  Once a shareholder has
opened an account with the minimum $1,000 investment, the automatic investment
option may be utilized to make regular electronic monthly investments of $100 or
more into such shareholder's account with the Fund. In order to utilize this
option, a shareholder must fill out and sign the appropriate section of the
application attached to this Prospectus or the EASE(SM) application which is
available from the Transfer Agent, the Fund, such shareholder's broker or dealer
or the Distributor. Once the Transfer Agent has received this application, such
shareholder's checking account at his or her designated local bank will be
debited each month in the amount authorized by such shareholder to purchase
shares of the Fund. Once enrolled in the EASE(SM) program, a shareholder may
change the monthly amount or terminate participation at any time by writing or
calling the Transfer Agent. Shareholders in the EASE(SM) program will receive a
confirmation of these transactions from the Fund monthly, and their regular bank
account statements will show the debit transaction each month.
 
  By electing to utilize any of the foregoing services, a shareholder authorizes

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., Business Week, Forbes or other industry 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.
 
  Please consult the Statement of Additional Information for more information
regarding the Fund's performance.

SHAREHOLDER SERVICES
- --------------------------------------------------------------------------------
 
  State Street Bank and Trust Company, c/o National Financial Data Services,
P.O. Box 419001, Kansas City, MO 64141-6001, transfer agent for the Fund,
performs bookkeeping, data processing and administrative services related to the
maintenance of shareholder accounts. When an initial investment is made in the
Fund, an account will be opened for each shareholder on the Fund's books and
shareholders will receive a confirmation of the opening of the account.
Shareholders will receive monthly statements giving details of all activity in
their account(s) and will also receive a statement whenever an investment or
withdrawal is made in or from their account. Information for federal income tax
purposes will be provided at the end of the year. Such statements will present
separately information with respect to each class of the Fund's shares. It is
expected that the transfer agency costs attributable to the Class B Shares and
Class C Shares will be higher than the transfer agency costs attributable to the
Class A Shares.
- --------------------------------------------------------------------------------
DESCRIPTION OF SHARES OF THE FUND
- --------------------------------------------------------------------------------
 
  The Fund is a sub-trust of the Van Kampen Merritt Tax Free Fund, a
Massachusetts business trust organized August 15, 1985 (the "Trust"). Shares of
the Trust entitle their holders to one vote per share; however, separate votes
are taken by each sub-trust on matters affecting an individual sub-trust.
 
  The authorized capitalization of the Fund consists of an unlimited number of
shares of beneficial interest, without 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 "The
Distribution and Service Plans."
 
  Pursuant to an order of the SEC, 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 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 Class B Shareholders 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 a majority of the shares present and voting at
such meeting. The Trust will assist such holders in communicating with other
shareholders of the Fund to the extent required by
 
                                       49

the Investment Company Act. More detailed information concerning the Trust is
set forth in the Statement of Additional Information.

                      STATEMENT OF ADDITIONAL INFORMATION
 
               VAN KAMPEN MERRITT NEW JERSEY TAX FREE INCOME FUND
 
  The 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 sub-trust of Van Kampen Merritt Tax Free Fund, a
Massachusetts business trust (the "Trust").

                             THE FUND AND THE TRUST
 
   
  The Fund is a separate sub-trust of the Trust, an open-end non-diversified
management investment company. At present, the Fund, Van Kampen Merritt Insured
Tax Free Income Fund, Van Kampen Merritt Tax Free High Income Fund, Van Kampen
Merritt Municipal Income Fund, Van Kampen Merritt Limited Term Municipal Income
Fund, Van Kampen Merritt California Insured Tax Free Fund, Van Kampen Merritt
New York Tax Free Income Fund and Van Kampen Merritt Florida Insured Tax Free
Income Fund have been organized as sub-trusts of the Trust and have commenced
investment operations. Van Kampen Merritt California Tax Free Income Fund, Van
Kampen Merritt Michigan Tax Free Income Fund, Van Kampen Merritt Missouri Tax
Free Income Fund and Van Kampen Merritt Ohio Tax Free Income Fund have been
organized as sub-trusts of the Trust but have not commenced investment
operations. Other sub-trusts may be organized and offered in the future.
    
 
  The Trust is an unincorporated business trust established under the laws of
the Commonwealth of Massachusetts by a Declaration of Trust dated August 15,
1985. The Declaration of Trust permits the Trustees to issue an unlimited number
of full and fractional shares in separate sub-trusts. Each share represents an
equal proportionate interest in the assets of the sub-trust with each other
share in such sub-trust and no interest in any other sub-trust. No sub-trust is
subject to the liabilities of any other sub-trust. The Declaration of Trust
provides that shareholders are not liable for any liabilities of the Trust or
any of its sub-trusts, requires inclusion of a clause to that effect in every
agreement entered into by the Trust or any of its sub-trusts 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 sub-trust on matters affecting an individual
sub-trust. For example, a change in investment policy for a sub-trust would be
voted upon by shareholders of only the sub-trust involved. 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 a majority of the shares present and voting at
such meeting.
 
  The Trustees may amend the Declaration of Trust (including with respect to any
sub-trust) in any manner without shareholder approval, except that the Trustees
may not adopt any amendment adversely affecting the rights of shareholders of
any sub-trust without approval by a majority of the shares of each affected
sub-trust present at a meeting of shareholders (or such higher vote as may be
required by the Investment Company Act of 1940, as amended (the "Investment
Company 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 bond
      market; however, the Fund will not invest more than 25% of its assets in
      industrial development bonds in a single industry.
 
   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
 
                                       B-2
<PAGE>   587
 
      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
      Securities and Exchange Commission (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.
 
   8. Invest in securities of other investment companies, except as part of a
      merger, consolidation or other acquisition and except that the Fund may
      invest up to 10% of its assets in tax-exempt investment companies that
      invest in securities rated comparably to those the Fund may invest in so
      long as the Fund does not own more than 3% of the outstanding voting stock
      of any tax-exempt investment company or securities of any tax-exempt
      investment company aggregating in value more than 5% of the total assets
      of the Fund.
 
   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 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 outstanding 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
 
                                       B-3
<PAGE>   588
 
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 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.
 
                                       B-4
<PAGE>   589
 
  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 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, 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
 
                                       B-5
<PAGE>   590
 
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 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 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
 
                                       B-6
<PAGE>   591
 
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 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 9.3% during 1992. Since then, the unemployment rate
fell to 6.7% during the fourth quarter of 1993. The jobless rate averaged 7.1%
during the first nine months of 1994, but this estimate is not comparable to
those prior to January because of major changes in the federal survey from which
these statistics are obtained.
 
  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.
 
  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.
 
                                       B-8
<PAGE>   593
 
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
 
                                       B-9
<PAGE>   594
 
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
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
 
                                      B-10
<PAGE>   595
 
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, 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.

<PAGE>   596
 
  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 Investment Company 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 high-grade 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
 
                                      B-12
<PAGE>   597
 
segregate liquid high-grade 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, high-grade assets 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 high-grade 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 Internal Revenue 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 Standard & Poor's 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 having as predominantly
  B         speculative characteristics with respect to capacity to pay interest and repay
  CCC       principal. 'BB' indicates the least degree of speculation and 'C' the highest.
  CC        While such debt will likely have some quality and protective characteristics,
  C         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.
</TABLE>
 
                                      B-14
<PAGE>   599
 
<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.
</TABLE>
 
            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.

            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 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>   601
 
  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.
</TABLE>

<TABLE>
  <S>       <C>
  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.
 
  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.
</TABLE>
    
 
  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 senior debt obligations which have an original maturity not
  exceeding one year. 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 (or supporting institutions) have a superior
     ability for repayment of senior short-term debt obligations.
 
       Issuers rated Prime-2 (or supporting institutions) have a strong ability
     for repayment of senior short-term debt obligations.
 
                                      B-18
<PAGE>   603
 
       Issuers rated Prime-3 (or supporting institutions) have an acceptable
     ability for repayment of senior short-term debt obligations.
 
    Issuers rated Not Prime do not fall within any of the Prime rating
  categories.

* Interested persons of each respective Fund as defined in the Investment
Company Act.
 
  Each of the foregoing trustees of the Fund acts as a trustee for other
investment companies advised by the Adviser, and each of the foregoing officers
holds the same positions with other investment companies advised by the Adviser.
 
  The compensation of the officers and trustees who are affiliated persons (as
defined in the Investment Company Act) of the Adviser is paid by the Adviser,
and the compensation of the officers and trustees who are affiliated persons of
Van Kampen American Capital Distributors, Inc. or Van Kampen American Capital,
 
                                      B-20

Inc. is paid by the respective entity. The Fund pays the compensation of all
other officers and trustees of the Fund. During the next year, the Fund expects
to pay trustees who are not affiliated persons of the Adviser, Van Kampen
American Capital Distributors, Inc. or Van Kampen American Capital, Inc. $2,500
per year, and $250 per meeting of the Board of Trustees, plus expenses. Under
the Fund's retirement plan, trustees who are not affiliated with the Adviser,
Van Kampen American Capital Distributors, Inc. or Van Kampen American Capital,
Inc., have at least ten years of service and retire at or after attaining the
age of 60, are eligible to receive a retirement benefit equal to the annual
retainer for each of the ten years following such trustee's retirement. Under
certain conditions, reduced benefits are available for early retirement. Under
the Fund's deferred compensation plan, a trustee who is not affiliated with the
Adviser, Van Kampen American Capital Distributors, Inc. or Van Kampen American
Capital, Inc. can elect to defer receipt of all or a portion of the trustee's
fees earned by such trustee until such trustee's retirement. The deferred
compensation earns a rate of return determined by reference to the Fund or other
Van Kampen Merritt Mutual funds advised by the Adviser as selected by the
trustee. To the extent permitted by the Investment Company Act, the Fund may
invest in securities of other Van Kampen Merritt mutual funds advised by the
Adviser 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.

(1)   Messrs. Merritt and McDonnell, Trustees of each Fund during fiscal year
      1994, are affiliated persons of the Adviser and are not eligible for
      compensation or retirement benefits from the Funds.
    
 
   
(2)   The Registrant is Van Kampen Merritt Tax Free Fund (the "Trust") which
      currently is comprised of 8 sub-trusts, including the Fund. The amounts
      shown in this column are accumulated from the Aggregate Compensation of
      each of these 8 sub-trusts during such sub-trust's last completed fiscal
      year prior to the date of this Statement of Additional Information.
      Beginning in October 1994 each Trustee, except Messrs. Gaughan and Whalen,
      began deferring his entire aggregate compensation paid by the Fund. The
      total combined amount of deferred compensation (including interest)
      accrued with respect to each Trustee as of December 31, 1994 is as
      follows: Mr. Kennedy, $14,737; Mr. Miller, $14,553; Mr. Nelson, $14,737
      and Mr. Robinson, $13,725.
    
 
   
(3)   The Retirement Plan commenced as of August 1, 1994 for the Fund. As of
      the end of the Fund's 1994 fiscal year, no amounts had been accrued for
      retirement benefits because such amounts were either zero or considered to
      be immaterial to the net assets of the Fund at such time. During the
      Fund's 1995 fiscal year, the Fund will accrue amounts for retirement
      benefits and include an amount, if any, for such Fund's 1994 fiscal year.
    
 
   
(4)   This is the estimated annual benefits payable per year for the 10-year
      period commencing in the year of such Trustee's retirement by a Fund
      assuming: the Trustee has 10 or more years of service on the Board of the
      Fund, retires at or after attaining the age of 60 and the annual retainer
      in the year prior to the Trustee's retirement is $2,500. Trustees retiring
      prior to the age of 60 or with fewer than 10 years of service for the Fund
      may receive reduced retirement benefits from such Fund.
    
 
   
(5)   The Fund Complex consists of 20 mutual funds advised by the Adviser. The
      amounts shown in this column are accumulated from the Aggregate
      Compensation of each of these 20 mutual funds in the Fund Complex during
      each fund's last completed fiscal year prior to the date of this Statement
      of Additional Information. The Adviser also serves as investment adviser
      for other mutual funds and

      closed-end investment companies; however, with the exception of Messrs.
      Merritt, McDonnell and Whalen, such mutual funds and closed-end investment
      companies do not have the same trustees as the Fund Complex. Combining the
      Fund Complex with other mutual funds and investment companies advised by
      the Adviser, Mr. Whalen received Total Compensation of $161,850.
    
 
   
  As of April 13, the trustees and officers as a group own less than 1% of the
shares of the Fund.
    
 
   
  No officer or trustee of the Fund owns or would be able to acquire 5% or more
of the common stock of VK/AC Holding, Inc.
    
 
   
  The authorized stock of the Fund currently consists of an unlimited number of
full and fractional shares of beneficial interest, without par value.

                     INVESTMENT ADVISORY AND OTHER SERVICES
 
INVESTMENT ADVISORY AGREEMENT
 
  Van Kampen American Capital Investment Advisory Corp. (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's principal
office is located at One Parkview Plaza, Oakbrook Terrace, Illinois 60181.
 
  The Adviser is a wholly-owned subsidiary of Van Kampen American Capital, Inc.,
which in turn is a wholly-owned subsidiary of VK/AC Holding, Inc. VK/AC Holding,
Inc. is controlled, through the ownership of a substantial majority of its
common stock, by The Clayton & Dubilier Private Equity Fund IV Limited
Partnership ("C&D L.P."), a Connecticut limited partnership. C&D L.P. is managed
by Clayton, Dubilier & Rice, Inc., a New York based private investment firm. The
General Partner of C&D L.P. is Clayton & Dubilier Associates IV Limited
Partnership ("C&D Associates L.P."). The general partners of C&D Associates
L.P., are Joseph L. Rice, III, B. Charles Ames, William A. Barbe, Alberto
Cribiore, Donald J. Gogel, Leon J. Hendrix, Jr., Hubbard C. Howe and Andrall E.
Pearson, each of whom is a principal of Clayton, Dubilier & Rice, Inc. In
addition, certain officers, directors and employees of Van Kampen American
Capital, Inc. own, in the aggregate, not more than 6% of the common stock of
VK/AC Holding, Inc. and have the right to acquire, upon the exercise of options,
approximately an additional 10% of the common stock of VK/AC Holding, Inc.
 
  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.
 
                                      B-22
<PAGE>   607
 
  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 sub-trust, 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 sub-trust
(or by the Fund's shareholders), and by the disinterested trustees in compliance
with the requirements of the Investment Company 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 period ended December 31, 1994, the Fund recognized advisory expenses
of $0.
 
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 Merritt mutual funds
distributed by the Distributor 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 Merritt funds based proportionally on
their respective net assets.
 
  For the period ended December 31, 1994, the Fund recognized expenses of
approximately $0 representing the Adviser's cost of providing accounting
services.
 
  SUPPORT SERVICES AGREEMENT. Under a support services agreement with the
Distributor the Fund receives support services for shareholders, including the
handling of all written and telephonic communications, except initial order
entry and other distribution related communications. Upon entering into such
agreement, the Fund realized a reduction in the fee which would have been paid
to the Transfer Agent if the Transfer Agent had provided such services. Payment
by the Fund for such services is made on cost basis for the employment of the
personnel and the equipment necessary to render the support services. The Fund,
and the other Van Kampen Merritt mutual funds distributed by the Distributor,
share such costs proportionately among themselves based upon their respective
net asset values.
 
  For the period ended December 31, 1994, the Fund recognized expenses of
approximately $0 representing the Distributor's cost of providing certain
support services.
 
  LEGAL SERVICES AGREEMENT. The Fund has entered into a Legal Services Agreement
pursuant to which Van Kampen American Capital, Inc. 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 Fund. 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
 
                                      B-23
<PAGE>   608
 
personnel, as well as overhead and the expenses related to the office space and
the equipment necessary to render the legal services. The Fund, and the other
Van Kampen Merritt mutual funds distributed by the Distributor, share one half
(50%) of such costs equally. The remaining one half (50%) of such costs are
allocated to specific funds based on specific time allocations, or in the event
services are attributable only to types of funds (i.e. closed-end or open-end),
the relative amount of time spent on each type of fund and then further
allocated between funds of that type based upon their respective net asset
values.
 
  For the period ended December 31, 1994, the Fund recognized expenses of
approximately $0 representing Van Kampen American Capital, Inc.'s cost of
providing legal services.
 
CUSTODIAN AND INDEPENDENT AUDITORS
 
  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 auditors for the Fund are KPMG Peat Marwick LLP, Chicago,
Illinois. The selection of independent auditors 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 sub-trust.
 
  The trustees have adopted certain policies incorporating the standards of Rule
17e-1 issued by the SEC under the Investment Company 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 each of its sub-trusts, including the Fund, will be treated as
separate corporations for income tax purposes. The Fund may be subject to tax if
it fails to distribute net capital gains, or if its annual distributions, as a
percentage of its income, are less than the distributions required by tax laws.
 
  The table below illustrates approximate equivalent taxable and tax-free yields
at the 1995 federal and New Jersey State gross 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.

* Combined state and federal tax top marginal rate. The tax rate brackets listed
  are the 1995 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 0.4% in the chart above.
 
                                THE DISTRIBUTOR
 
  Shares of the Fund are offered continuously through the Distributor Inc., One
Parkview Plaza, Oakbrook Terrace, Illinois 60181. The Distributor Inc. is a
wholly-owned subsidiary of Van Kampen American Capital, Inc., which is a
subsidiary of VK/AC Holding, Inc., a Delaware corporation that is controlled
through an ownership of a substantial majority of its common stock, by The
Clayton & Dubilier Private Equity Fund IV Limited Partnership ("C & D L.P."), a
Connecticut limited partnership. In addition, certain officers, directors
 
                                      B-25
<PAGE>   610
 
and employees of Van Kampen American Capital, Inc., and its subsidiaries own, in
the aggregate not more than 6% of the common stock of VK/AC Holding, Inc. and
have the right to acquire, upon the exercise of options, approximately an
additional 10% of the common stock of VK/AC Holding, Inc. C & D L.P. is managed
by Clayton, Dubilier & Rice, Inc. Clayton & Dubilier Associates IV Limited
Partnership ("C & D Associates L.P.") is the general partner of C & D L.P.
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.
 
  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 Investment
Company 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, 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 banks 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 banks 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 sub-trust, 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 period ended December 31, 1994, the Fund has recognized expenses under
the Plans of $2,901, $21,519 and $715 for the Class A Shares, Class B Shares and
Class C Shares, respectively, of which $0 and $0 represent payments to financial
intermediaries under the Selling Agreements for Class A Shares and Class B
Shares, respectively. For the period ended December 31, 1994, the Fund
reimbursed the Distributor $0 and $0 for advertising expenses and $0 and $0 for
compensation of the Distributor's sales personnel for Class A Shares and Class B
Shares, respectively.

                            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. 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. 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 official
statement utilized in connection with the issuance of the $600,000,000 State of
New Jersey, Tax and Revenue Anticipation Notes, Series Fiscal 1995A, dated
November 30, 1994, with the exception of some of the information provided below
regarding the proposed State takeover of the Newark public school district,
which information was derived from information available to the public. 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 1,062 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 almost
one-fourth 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 1993,
accelerated to .59%. While this rate of growth is less than that for the United
States, it compares favorably with other Middle Atlantic States. New York has
shown a 0.35 percent annual rate of increase since 1990 and Pennsylvania's
population has increased 0.43 percent per year.
 
                                      B-29
<PAGE>   614
 
  The small increase in the State's total population during the 1970s and
throughout the 1980s 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 $204.1 billion for 1992 and
$210.6 billion for 1993, an increase of 3.2%. Nationally, total personal income
grew by 4.4 percent between 1992 and 1993, while in New York and Pennsylvania it
grew by 3.6 percent and 3.1 percent, respectively. Based on 1973 levels, the
personal income index in 1993 stood at 478.9 for New Jersey, 416.6 for New York
and 422.4 for Pennsylvania. The United States index stood at 490.7 (1973 = 100).
 
  Historically, New Jersey's average per capita income has been well above the
national average. The differential narrowed during the 1970s but widened in the
1980s. In 1993, the State ranked second among all states in per capita personal
income ($26,732). It ranked higher than New York, with per capita income of
$24,771 and Pennsylvania with $21,241. Only Connecticut, with $27,957, exceeded
New Jersey's $26,732.
 
  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, construction
activity had already been declining in New Jersey for nearly two years. As the
rapid acceleration of real estate prices forced many would-be homeowners out of
the market and high non-residential vacancy rates reduced new commitments for
offices and commercial facilities, construction employment began to decline;
also growth had tapered off markedly in the service sectors and the long-term
downtrend 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 and trucking and warehousing. The net
effect was a decline in the State's total nonfarm wage and salary employment
from a peak of 3,706,400 in March 1989 to a low of 3,445,000 in March 1992. This
loss has been followed by an employment gain of 118,700 from March 1992 to
September 1994.
 
  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 9.3%
during 1992. Since then, the unemployment rate fell to 6.7% during the fourth
quarter of 1993. The jobless rate averaged 7.1% during the first nine months of
1994, but this estimate is not comparable to those prior to January because of
major changes in the federal survey from which these statistics are obtained.
 
  In the first nine months of 1994, relative to the same period a year ago, job
growth took place in services (3.5%) and construction (5.7%), more moderate
growth took place in trade (1.9%), transportation and utilities (1.2%) and
finance/ insurance/ real estate (1.4%), while manufacturing and government
declined (by 1.5% and 0.1%, respectively). The net result was a 1.6% increase in
average employment during the first nine months of 1994 compared to the first
nine months of 1993.
 
  The insured unemployment rate, i.e. the number of individuals claiming
benefits as a percentage of the number of workers covered by Unemployment
Insurance, stopped rising during the winter of 1991-1992 and had been stable at
about 4.1 percent through April of 1992 before beginning a gradual decline to
its May, 1994 level of 3.2 percent. It has since stabilized at about that level.
After paying out approximately $125 million, the State's Emergency Unemployment
Benefits Program ended on November 17, 1991 with the enactment of the Federal
Emergency Unemployment Compensation (EUC) Program. Through the expiration of the
EUC program on April 30, 1994, over $2.1 billion had been disbursed to claimants
who exhausted their entitlement under the regular state program. Benefits under
EUC are financed 100 percent by the federal government and thus do not impact
the State's trust fund.
 
  Total construction contracts awarded in New Jersey have turned around, rising
by 8.6% in 1993 compared with 1992. By far, the largest boost came from
residential construction awards which increased by 37.7% in 1993 compared with
1992. In addition, nonresidential building construction awards have turned
around, posting a 6.9% gain. Nonbuilding construction awards increased
approximately 4% in the first eight months of 1994 compared with the same period
in 1993.

  New passenger car registrations issued during 1993 were up 12% in New Jersey
from a year earlier. Registrations of new light trucks and vans (up to 10,000
lbs.) advanced strongly in 1993 and jumped nearly 20% during the
January-to-August 1994 period relative to the same period last year. Retail
sales for 1993 were up 1.7% compared to 1992. Sales have continued strong with
retail sales up 8.5% for the first seven months of 1994 compared with the same
period a year ago. Retailers, such as those selling appliances and home
furnishings, should benefit from increased residential construction. Car, light
truck and van dealers should also benefit from the high (eight years) average
age of autos on the road.
 
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. 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. Consequently, there are twelve casinos currently
operating in Atlantic City.
 
  For the year ended December 31, 1992, eight of the twelve operating casinos
reported a profit. The industry as a whole reported net income of $164.7 million
for the year, including $91.4 million in net income reported by the Trump's
Castle. Trump's Castle's net income for the year reflected $126.8 million in
extraordinary income related to the restructuring of long-term debt in
connection with its plan of reorganization.
 
  For the year ended December 31, 1993, the industry as a whole reported a net
loss of $1.2 million, reflecting a $165.9 million decrease from the net income
of $164.7 million reported for the prior comparable period. This decline in
industry net income primarily reflects the absence of the $126.8 million
extraordinary gain reported by Trump's Castle in the prior comparable period and
$43.4 million in extraordinary losses reported by Bally's Grand and Bally's Park
Place in connection with changes in the method of accounting for income taxes.
 
  For the years ended December 31, 1992 and 1993, the casino industry reported
"Win" of $3.2 billion and $3.3 billion, respectively. For the nine months ended
September 30, 1994 the casino industry reported "Win" of $2.6 billion. "Win"
represents the amount a casino wins at the slot machines and table games before
operating expenses and taxes are deducted.
 
  For the years ended December 31, 1992 and 1993, the State collected revenue
taxes for programs to assist the elderly and disabled of $255.3 million and
$262.9 million, respectively. For the nine months ended September 30, 1994, the
State collected revenue taxes of $205.2 million. From May 20, 1978, the date the
first casino opened, through September 30, 1994, the industry has paid a total
of $2.8 billion to the State for these programs. As of September 30, 1994, the
fund has earned $113.1 million in interest.
 
  In 1993 there were 43,900 jobs in the hotel/casinos; total employment in the
Atlantic County metropolitan statistical area has grown from 89,000 persons in
1975 to 168,300 in 1993. The number of visitors to Atlantic City increased 331.4
percent from 7.0 million for 1978 to 30.2 million for 1993.
 
  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, 1994, the Lottery has generated
over $16.5 billion in gross revenues and $8.1 billion in prizes and contributed
$6.93 billion to the State.
 
  The State Department of Higher Education has received approximately $1.912
billion in Lottery funds. For elementary and secondary education, the State
Department of Education has received approximately $1.559 billion. State
institutions have received a total of $3.455 billion in Lottery monies.
 
  In Fiscal Year 1994, gross revenues totalled $1.45 billion, of which 49.94
percent was returned in prizes, 41.65 percent went to State education and
institutions, 7.02 percent was paid to banks and lottery companies and 1.39
percent 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, Enterprise Funds, University Funds, General Fixed Asset
Account Group and its General Long-Term Debt Account Group.
 
  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 appropriation 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 Services Funds are used to account for the
accumulation of resources for, and the payment of, principal and redemption
premium, if any, of and 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 1994" refers to the State's fiscal year beginning July 1,
1993 and ending June 30, 1994. 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
 
                                      B-32
<PAGE>   617
 
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 YEAR 1994 AND 1995 REVENUE ESTIMATES
 
  Sales and Use Tax. The Fiscal Year 1995 Appropriations Act forecasts Sales and
Use Tax collections for Fiscal Year 1995 of $3,980 million, a 5.3% increase from
unaudited revenue for Fiscal Year 1994. Unaudited revenue for Fiscal Year 1994
for the Sales and Use Tax of $3,778.4 million represents a 3.5% increase from
actual receipts for Fiscal Year 1993.
 
  Gross Income Tax. The Fiscal Year 1995 Appropriations Act forecasts Gross
Income Tax collections for Fiscal Year 1995 of $4.582 million, a 2.4% increase
from unaudited revenue for Fiscal Year 1994. Included in the Fiscal Year 1995
Gross Income Tax forecast is a 5% reduction of personal income tax rates
effective January 1, 1994 and a further 10% reduction of personal income tax
rates effective January 1, 1995. The Fiscal Year 1995 Gross Income Tax estimates
a $549 million reduction related to these tax cuts. Unaudited revenue for Fiscal
Year 1994 for the Gross Income Tax of $4,475.1 million represents a 2.9%
increase from actual receipts for Fiscal Year 1993.
 
  Corporation Business Tax. The Fiscal Year 1995 Appropriations Act forecasts
Corporation Business Tax collections for Fiscal Year 1995 of $915 million, a 14%
decrease from unaudited revenue for Fiscal Year 1994. Included in the
Corporation Business Tax forecast is a reduction in the Corporation Business Tax
rate from 9.375% to 9.0% of net New Jersey income. Unaudited revenue for Fiscal
Year 1994 for the Corporation Business Tax of $1,063.1 million represents a
10.6% increase from actual receipts for Fiscal Year 1993.
 
  Other Miscellaneous Taxes, Fees and Revenues. The Fiscal Year 1995
Appropriations Act forecasts Other Miscellaneous Taxes, Fees and Revenues
collections for Fiscal Year 1995 of $1,338.5 million, a 15.6% decrease from
unaudited revenue for Fiscal Year 1994 for Other Miscellaneous Taxes, Fees and
Revenues.
 
                                      B-33
<PAGE>   618
 
Included in the Other Miscellaneous Taxes, Fees and Revenues forecast is a
decline of $426 million in the Public Utility Gross receipts and Franchise tax
in accordance with the collection date changes that were legislated in 1991.
 
  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.
 
  Pending Litigation. In connection with the current Fiscal Year 1995 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."
 
  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.
 
  The State has made appropriations for principal and interest payments for
general obligation bonds for Fiscal Years 1991 through 1994 in the amounts of
$388.5 million, $410.6 million, $444.3 million and $119.9 million respectively.
For Fiscal Year 1995 $103.5 million has been appropriated for principal and
interest payments for general obligation bonds.
 
PROGRAMS FUNDED UNDER FISCAL YEAR 1995 ADJUSTED APPROPRIATIONS
 
  Of the $15,291.0 million appropriated in Fiscal Year 1995 from the General
Fund, the Property Tax Relief Fund, the Casino Control Fund, the Casino Revenue
Fund and the Gubernatorial Elections Fund, $5,782.2 million (37.8%) is
appropriated for State Aid to Local Governments, $3,761.6 million (24.6%) is
appropriated for Grants-in-Aid, $5,203.1 million (34.0%) for Direct State
Services, $103.5 million (0.7%) for Debt Service on State general obligation
bonds and $440.6 million (2.9%) for Capital Construction.
 
STATE AID TO LOCAL GOVERNMENTS
 
  State Aid to Local Governments is the largest portion of Fiscal Year 1995
appropriations. In Fiscal Year 1995, $5,782.2 million of the State's
appropriations consist of funds which are distributed to municipalities,
counties and school districts. The largest State Aid appropriations, in the
amount of $3,900.1 million, is provided for local elementary and secondary
education programs. Appropriations to the Department of Community Affairs total
$635.1 million in State Aid monies for Fiscal Year 1995. Appropriations to the
State Department of the Treasury total $321.3 million in State Aid monies for
Fiscal Year 1995. Other appropriations of State Aid in Fiscal Year 1995 include:
welfare programs ($499.1 million); aid to county colleges ($123.2 million); and
aid to county mental hospitals ($79.4 million).
 
DIRECT STATE SERVICES
 
  The second largest portion of appropriations in Fiscal Year 1995 is applied to
Direct State Services: the operation of State government's seventeen
departments, the Executive Office, several commissions, the State Legislature
and the Judiciary. In Fiscal Year 1995, appropriations for Direct State Services
aggregate to $5,203.1 million.
 
  $595.3 million is appropriated for programs administered by the State
Department of Human Services. The State Department of Labor is appropriated
$49.3 million for the administration of programs for workers compensation,
unemployment and disability insurance, manpower development and health safety
inspection. The State Department of Health is appropriated $32.3 million for the
prevention and treatment of diseases,
 
                                      B-34
<PAGE>   619
 
alcohol and drug abuse programs, regulation of health care facilities and the
uncompensated care program. $689.3 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. $932.5 million is
appropriated to the State Department of Law and Public Safety and the State
Department of Corrections. $92.3 million is appropriated to the State Department
of Transportation for the various programs it administers, such as the
maintenance and improvement of the State highway system. $176.6 million is
appropriated to the State 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 1995 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 1995 for grants-in-aid is $3,761.6 million.
 
  $2,769.3 million is appropriated for programs administered by the Department
of Human Services. Of that amount, $1,942.4 million is for medical services
provided under the Medicaid program, $171.5 million is for community programs
for the developmentally disabled, $139.1 million is for community programs for
the mentally ill, $161.4 million is for pharmaceutical assistance to the aged
and disabled, $214.4 million is for grant programs administered by the Division
of Youth and Family Services, $73.4 million is for the Lifeline program, and
$48.8 million is for welfare reform and homeless services.
 
  $318.9 million is appropriated to the Department of the Treasury for the
Homestead Rebate program, which provides property tax relief to homeowners and
renters.
 
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 premium payments, if any, required to fully pay the bonds. The
appropriation for the debt service obligation on outstanding indebtedness is
$103.5 million for Fiscal Year 1995.
 
  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 $59,000,000 State of New Jersey General Obligation Bonds on November 23,
1994, which was the most recent issuance of this type of bond, 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. This
amount represents 2.9% of the total Fiscal Year 1995 Budget. In Fiscal Year
1995, the amount appropriated to this purpose is $440.6 million.
 
  All appropriations for capital projects and all proposals for State bond
authorizations 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.

                        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 Authority 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 Authority'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. The rental payments required to be made by the State under such
lease agreements are sufficient to cover debt service on the bonds issued by the
EDA to finance the acquisition and construction of such projects and other
amounts payable to the EDA, including certain administrative expenses of the
EDA, and such rental payments are subject to annual appropriation by the State
Legislature.
 
  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 completed eleven lease purchase agreements which have resulted in
the issuance of Certificates of Participation totaling $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 rentals
payable by the State will be made from monies appropriated by the State
Legislature. The State intends to continue to use this financing technique for a
substantial portion of its future equipment requirements.
 
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 December 31, 1993, 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
$211,227,841 have been retired and $62,846,159 are still outstanding. As of June
30, 1993, $81,898,853 of county college bonds or notes have been authorized or
issued of which $42,043,825 have been retired. 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-36
<PAGE>   621
 
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. There are approximately $475,373,000 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. The TTFA Act
authorizes the State Treasurer to credit to the TTFA a minimum of $320,250,000
per year. 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 these revenues 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 requirement that the Legislature make such
appropriation. The TTFA Act specifies that the TTFA's legal existence shall not
continue beyond 22 years from the date of enactment of the TTFA Act.
 
  Pursuant to the TTFA Act, the aggregate principal amount of the TTFA's bonds,
notes or other obligations outstanding at any one time may not exceed $1.7
billion. This amount is reduced by certain payments to the TTFA by the State in
excess of the Contract amount. 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.
 
                               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 is unwilling to
prepare 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; amounts approved by referendum; and, in the case of
municipalities only, to fund the preceding year's cash deficit or to reserve for
shortfalls in tax collections. 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 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.
 
  Chapter 75 of the Pamphlet Laws of 1991, signed into law on March 28, 1991
requires certain municipalities and permits all other municipalities to adopt
the State fiscal year in place of the existing calendar fiscal year.
Municipalities that change fiscal years must adopt a six month transition budget
for
 
                                      B-38
<PAGE>   623
 
January to June. Since expenditures would be expected to exceed revenues
primarily because state aid for the calendar year would not be received by the
municipality until after the end of the transition year budget, the act
authorizes the issuance of Fiscal Year Adjustment Bonds to fund the one time
deficit for the six month transition budget. The act provides that the deficit
in the six month transition budget may be funded initially with bond
anticipation notes based on the estimated deficit in the six month transition
budget. 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. The purpose of the Act is to assist municipalities
that are heavily dependent on state aid and that have had to issue tax
anticipation notes to fund operating cash flow deficits each year. While the act
does not authorize counties to change their fiscal years, it does provide that
counties with cash flow deficits may issue Fiscal Year Adjustment Bonds as well.
 
  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.
 
  There are 567 municipalities and 21 counties in New Jersey. During 1990, 1991
and 1992 no county exceeded its statutory debt limitations or incurred a cash
deficit in excess of 4 percent of its tax levy. The number of municipalities
which have a cash deficit greater than 4 percent of their tax levies was zero
for 1992. The number of municipalities which exceeded statutory debt limits was
five as of December 31, 1993. 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 in extreme cases to take over the operation of local school
districts which cannot or will not correct severe and complex educational
deficiencies. Pursuant to a 1987 amendment to the Public School Education Act of
1975 (the "School Act"), the State Board of Education may direct the removal of
the local district board of education and the creation of a State operated
school district. The State operated school district would be under the direction
of a State appointed superintendent who would have 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. On July 22, 1994, the Commissioner of
 
                                      B-39
<PAGE>   624
 
Education issued an order to show cause why the Newark school district should
not become State operated. The hearing in that matter was scheduled to begin in
February 1995. On April 13, 1995, a state administrative law judge issued an
order for the State of New Jersey to take over the administration of the Newark
school district. After a short period in which the Newark school board and the
State may file objections and responses respectively, the State Commissioner of
Education makes a recommendation to the State Board of Education, which makes
the final administrative determination. That determination is subject to appeal
to the Appellate Division of the State Superior Court.
 
  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 has approximately 20 days to determine the
amount necessary to be appropriated for each item appearing in such budget.
Should the governing body fail to certify any amount determined by the Board of
Education to be necessary for any item rejected at the election, 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 current expense
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 only if the Commissioner determines that
additional funds are required to provide a thorough and efficient education. The
Supreme Court of New Jersey has ordered that the Legislature adopt a new funding
formula by September 1996 which would provide for substantially equivalent
expenditures in the poor urban districts and wealthy suburban districts.
 
  The Commissioner must also review every proposed local school district budget
for the next school year. The Commissioner examines 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 his
view they are insufficient, the Commissioner must 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
 
                                      B-40
<PAGE>   625
 
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 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 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.
 
  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 $239,235,650 by various school districts as of
June 30, 1994 and $931,737,570 by various municipalities as of June 30, 1994.
 
  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, 1994, the book value of the Fund's assets aggregated $86,264,837 and the
reserve, computed as of
 
                                      B-41
<PAGE>   626
 
June 30, 1994, amounted to $35,528,287. 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).
 
Local Financing Authorities
 
  The Local Authorities Fiscal Control Law provides for State supervision 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, 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, 1993 there were 200 locally created authorities with a total
outstanding capital debt of $6,963,564,405 (figures do not include housing
authorities and redevelopment agencies). This amount reflects outstanding bonds,
notes, loans and mortgages payable by the authorities as of their respective
fiscal years ended nearest to June 30, 1993.
 
                                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 65,000 full time and 4,000 part time
employees are paid through the State payroll system. Of the 69,000 employees,
56,000 are represented by certified or recognized exclusive majority
representatives and are organized into various negotiation units.
 
  The Fiscal Year 1995 Budget is expected to reduce the workforce through
attrition, voluntary furlough and layoff of State employees during Fiscal Year
1995.
 
                               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 386,931 of the total
426,144 active members covered by all State-administered plans. The other
systems are Police and Firemen's Retirement System ("PFRS") (36,326 members),
Consolidated Police and Firemen's Pension Fund ("CP&FPF") (no active members),
State Police Retirement System ("SPRS") (2,475 members), Judicial Retirement
System ("JRS") (411 members) and Prison Officers' Pension Fund ("POPF") (1
member).
 
                                      B-42
<PAGE>   627
 
  The various pension funds were analyzed between March 31, 1993 and July 1,
1993 by independent actuaries who reported 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 $33.7 billion at the
valuation dates. The studies indicated that the market value of all assets of
the funds was $38.0 billion which, when compared to the $33.7 billion
Accumulated Benefit Obligation, represents a funding level of 112.6%. 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 $41.3 billion. The funding level for the projected
benefits is 91.9%.
 
  $305.9 million is provided in the Fiscal Year 1995 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 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 1995 budget. The
State intends to vigorously defend this action.

  County/State Disputes Concerning Social Security Recoveries.  There are
presently several cases pending in the State courts challenging the methods by
which the State Department of Human Services shares with county governments the
maintenance recoveries and costs for residents in State psychiatric hospitals
and residential facilities for the developmentally disabled. In County of Essex
v. Waldman, et al., Essex County challenged the State's policy of sharing
federal Social Security recoveries on a 50%-50% basis with the County. Essex
County maintains that State law has, since 1980, required that 100% of the
recoveries be paid to the County. On December 6, 1990, the Appellate Division
upheld the trial court's ruling allowing the County to receive 100% of
recoveries, but refused to allow recovery retroactive to 1980, instead fixing
January 25, 1989 as the effective date of the ruling as to Essex County. A
petition for certification by the County of Essex, and a cross-petition by the
State, were denied by the New Jersey Supreme Court on May 28, 1991. The Counties
of Morris, Passaic, Middlesex, Hudson, Bergen, Union, Cumberland, Monmouth,
Mercer, Hunterdon and Camden all filed similar actions which were stayed (except
in the cases of Hudson and Camden) pending the outcome in the County of Essex
case, and all actions (except in the case of Mercer) are now on appeal.
Retroactive recoveries in those cases may also be limited, as in the County of
Essex matter. By administrative order dated July 22, 1991, the Commissioner
determined that State liability to all counties (with the exception of Essex
County) would run as of December 6, 1990. The Counties of Bergen, Burlington,
Camden, Cumberland, Hunterdon, Hudson, Middlesex, Monmouth, Morris, Somerset and
Union have appealed that administrative order in the Superior Court, Appellate
Division.
 
  In County of Essex v. Commissioner, Department of Human Services, et al.,
Essex County has sought the return of moneys it has paid since 1980 for
maintenance of Medicaid or Medicare eligible residents of institutions and
facilities for the developmentally disabled, arguing that State law relieved the
County of maintenance responsibility for those persons. The trial court ruled in
Essex County's favor, but made its ruling effective as of March 30, 1989. The
Appellate Division affirmed that decision on June 14, 1991. Petitions for
certification by both parties were denied by the New Jersey Supreme Court on
November 12, 1991. Hunterdon, Mercer, Passaic, Middlesex, Hudson, Bergen, Union,
Cumberland, Camden and Monmouth Counties filed similar actions, which were
stayed (except in the cases of Hudson and Camden) pending a decision in the
Essex County case, and all actions (except in the case of Mercer) are now on
appeal. By administrative order, dated July 22, 1991, the Commissioner
determined that, subject to action by the New Jersey Supreme Court, the State's
liability to all counties (with the exception of Essex County) will run as of
June 14, 1991. The Counties of Bergen, Burlington, Camden, Cumberland,
Hunterdon, Hudson, Middlesex, Monmouth, Morris, Passaic and Union appealed the
administrative order to the Superior Court, Appellate Division.
 
  In March 1994, the Appellate Division ruled that all counties were entitled to
100% of social security benefits and other maintenance recoveries received by
the State and were entitled to credits for payments made to the State for the
maintenance of Medicare and Medicaid-eligible county residents in State
facilities for the mentally ill and developmentally disabled from the respective
dates in 1989 of the trial court's decisions in County of Essex v. Waldman
(April 14, 1989) and County of Essex v. Commissioner, Department of Human
Services, et al. (September 25, 1989). In May 1994, the Appellate Division
granted the State's Motion for Reconsideration and modified its earlier ruling.
A request by several counties asking the Court to reconsider the modification
was denied. The State and several counties have filed separate notices of
Petition for Certification asking the New Jersey Supreme Court to review
portions of the case.
 
  New Jersey Association of Health Care Facilities, Inc. et al. v. Gibbs, et al.
 In this case, which was filed in the United States District Court for the
District of New Jersey on May 8, 1990, plaintiffs allege that the Department of
Human Services, Division of Medical Assistance and Health Services, has
implemented unreasonably low Medicaid payment rates for long-term care
facilities in New Jersey. Plaintiffs claim that the rates are not sufficient to
cover their actual costs of providing services to Medicaid patients and that
this has had an adverse impact on the quality of services they are able to
provide to Medicaid patients. This matter was certified as a class action on
behalf of all New Jersey long-term care facilities, which were providing
services to Medicaid recipients on March 11, 1991. They seek a declaration that
the Department of Human Services has violated federal law in the setting and
paying of Fiscal Year 1990 long-term care facility Medicaid payment rates and an
injunction against the Department requiring it to comply with federal law in the
setting of such rates. Plaintiffs also seek costs and attorneys' fees. A final
decision in favor of the plaintiffs could require the
 
                                      B-44
<PAGE>   629
 
State to make substantial expenditures. Plaintiffs filed a motion for a
preliminary injunction, which was denied by the court following a hearing. The
denial was appealed to the Third Circuit on October 30, 1992. In an Order dated
November 4, 1993, the Third Circuit affirmed the decision of the District Court.
On September 30, 1994 the District Court approved an Order dismissing the case
with prejudice. Pursuant to the terms of that Order, plaintiffs may not bring a
claim arising under State law or regulations, provider agreements,
administrative appeals or contract which incorporates, by reference or
otherwise, the Boren amendment, 42 USC sec. 1396a(a)(13)(A). The Boren amendment
requires the State to pay the rates that reasonably reimburse an efficiently and
economically operated nursing home.
 
  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, appellates
filed an application for injunctive relief, seeking to stay any collection,
which application was denied. On August 15, 1994 a second challenge to the
collection of the assessment was filed with the Appellate Division. This case,
New Jersey Hospital Association v. Fishman, represents a challenge by the
Association to any collection of the assessment post-fiscal year 1994 on the
ground that the Legislature intended only a single year assessment. A request
for injunctive relief to prevent assessments during fiscal year 1995 was denied
by the court. The assessment is intended to produce a total of approximately
three million dollars per month from all New Jersey hospitals. The State intends
to vigorously defend this action.
 
  Barnert Memorial Hospital v. Commissioner of Health. This case concerns an
appeal by various hospitals of the Commissioner's calculation of the hospital
assessment required by the Health Care Cost Reduction Act of 1991. That Act
required that the Commissioner assess State hospitals .53% of their 1991
approved revenue base, for a two year period. The amounts collected were paid
into the Health Care Cost Reduction Fund to help offset uncompensated care
costs. In their appeal, the hospitals alleged that the Commissioner's assessment
effectively doubled the amount intended by the Legislature. In a decision dated
April 30, 1993 the Appellate Division agreed with the hospitals' argument and
reversed the Commissioner's calculation (although the Court rejected numerous
other arguments raised by the hospitals). The Court did not specifically rule on
the disposition of the amount in dispute, which at a maximum could total $37
million. The Commissioner filed a petition for certification with the Supreme
Court, and appellants filed a cross-petition. The Commissioner's motion for a
stay of the decision was denied by the Appellate Division on June 29, 1993; on
the same day the Appellate Division similarly denied a motion filed by the
hospitals seeking to compel the Commissioner to refund the monies claimed to be
owed to them. The Commissioner subsequently filed with the Supreme Court on July
21, 1993 a motion for a stay pending final disposition of the case, and the
hospitals filed a motion to enforce litigants rights seeking return of the
monies. In Orders dated September 9, 1993, the Supreme Court denied the
petition, cross-petition and the motions to enforce litigants, rights and for a
stay. On November 24, 1993, Appellants filed a second motion to enforce
litigants' rights in the Appellate Division. The Appellate Division granted the
motion and ordered that the successful claimants be refunded the amount of their
overpayments. The money was refunded in April 1994 in the amount of $4,636,576.
 
  On July 5, 1994 the New Jersey Hospital Association and 67 individual
hospitals filed a Verified Complaint and an Order to Show Cause in the Superior
Court of New Jersey, Mercer County Law Division seeking the same relief afforded
the Barnert litigants: a return of those monies collected by the Department
pursuant to the .53% assessment for the period after July 1992. The total amount
of refund demanded by plaintiffs totals $20,752,918. The case is docketed as New
Jersey Hospital Association, et al. v. Leonard Fishman.
 
  Fair Automobile Insurance Reform Act Litigation. On March 12, 1990, the Fair
Automobile Insurance Reform Act of 1990 ("FAIR Act") was enacted into law. It
recently was amended by L. 1994, c. 57. The FAIR Act substantially altered New
Jersey's statutory scheme governing private passenger automobile insurance. The
New Jersey Automobile Full Insurance Underwriting Association ("JUA") an
unincorporated non-profit association created in 1983 to provide automobile
insurance to those unable to secure such coverage
 
                                      B-45
<PAGE>   630
 
in the voluntary market, was precluded from issuing or renewing automobile
insurance policies after October 1, 1990. The FAIR Act includes provisions
governing the transition of drivers insured by the JUA first to the Market
Transition Facility ("MTF") and then to the voluntary market and, to the extent
such coverage is not available, to an Assigned Risk Plan. The FAIR Act also
provided for the imposition of taxes and assessments to meet the financial
obligations of the JUA, which are not debts, liabilities or obligations of the
State. The FAIR Act's revenue raising measures were not reflected in the current
budget because the anticipated revenues are to be applied by statute to the JUA
financial obligations. L. 1994, c. 57 provides for the application of these
anticipated revenues to the MTF. The FAIR Act also provides for the making of
assessments by the New Jersey Property Liability Insurance Guaranty Association
upon property and casualty liability insurers in order to raise $160 million
dollars per year for the period 1990 to 1997. The funds will also be used for
the JUA and MTF.
 
  Litigation challenging various portions of the FAIR Act still remains pending.
"As applied" challenges to the FAIR Act surtax and assessment provisions have
been brought. Litigation was filed in the Mercer County Superior Court-Chancery
Division, by Allstate and State Farm alleging that their constitutional rights
have been violated and that they are entitled to refunds of FAIR Act surtaxes
and assessments. The Allstate matter is settled. The State Farm matter is
pending an appeal.
 
  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. An
independent study estimated an aggregate potential exposure of $50 million for
tort claims pending as of January 1, 1982. It is estimated that were a similar
study made of claims currently pending, the amount of such estimated exposure
would be somewhat higher.
 
  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 $38 million for tort and
medical malpractice claims pending as of June 30, 1992. 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"), alleges tort and
contractual claims against the State and the NJDEPE associated with a resource
recovery facility which plaintiffs had once planned to build. The plaintiffs
allege that the State of New Jersey ("State") and the Department of
Environmental Protection and Energy ("DEPE") violated a 1984 consent order
concerning the construction of a resource recovery facility in Passaic County.
The State's position is that there was no obligation or duty on the part of the
State or DEPE concerning the project. Plaintiffs' complaint alleges
approximately thirty million dollars ($30,000,000) in damages against the State
and the DEPE. The State intends to vigorously defend this action.
 
                                      B-46
<PAGE>   631
 
  Pelletier, et al. v. Waldman, et al. In this case, several Medicaid eligible
children and the Association for Children of New Jersey challenge the adequacy
of Medicaid reimbursement for services rendered by doctors and dentists to
Medicaid eligible children. Plaintiffs allege that the Department of Human
Services, Division of Medical Assistance and Health Services has, by virtue of
unreasonably low Medicaid payment rates to doctors and dentists, failed to
attract a sufficient number of medical professionals to provide adequate access
to health care services for Medicaid eligible children. Plaintiffs intend to
seek class action certification on behalf of all New Jersey Medicaid eligible
children. Plaintiffs seek a declaration that the Department of Human Services
has violated federal law by setting rates that do not provide access to the
Medicaid Early and Periodic Screening Diagnosis and Treatment ("EPSDT") program
and an injunction against the Department requiring it to comply with federal law
in the setting of such rates. Plaintiffs also seek costs and attorneys' fees. A
final decision in favor of the plaintiffs could require the State to make
substantial expenditures. The Complaint was filed on June 9, 1993. An answer was
filed on behalf of the State defendants; the parties are currently in mediation.
 
  Robert E. Brennan v. Richard Barry et. al. On May 19, 1993 plaintiff Robert
Brennan filed suit against two members of the New Jersey Bureau of Securities,
Richard Barry, the Supervisor of Enforcement and Jared Silverman, Bureau Chief.
Brennan's complaint alleges various causes of action for defamation and injury
to reputation under section 1983 and state law. Plaintiff also alleges claims of
abuse of process and improper disclosure of private facts based on the Bureau's
ongoing investigation of certain publicly traded securities. The State's motion
for summary judgment was argued on November 18, 1994. A decision was expected by
January, 1995. The State is unable to estimate its exposure for this claim and
intends to defend this suit vigorously.
 
  Camden Co. v. Waldman, et al. In this case against the Department of Human
Services, the Attorney General and the State Treasurer, Camden County seeks an
estimated $22.8 million it claims that the Department owes it from federal
funding the State recently received for disproportionate share hospital payments
made to county psychiatric facilities during July 1, 1988 through July 1, 1991.
Camden County contends that the Essex decisions mandate sharing of the federal
funding. These decisions dealt with sharing maintenance costs when there have
been social security and Medicaid payment recoveries. The State will contend
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 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 and Sussex counties. The Middlesex, Monmouth,
Atlantic, Union, Ocean, Mercer, Morris and Hudson County cases were transferred
to the Appellate Division, and Sussex County's lawsuit is in the process of
being similarly transferred. Finally, Morris County filed a lawsuit in the Law
Division and also directly with the Appellate Division. The Atlantic, Camden and
Monmouth counties cases have been consolidated. The remaining matters will be
heard on a back to back basis by the Appellate Division. The counties whose
cases have been consolidated have filed their appellate brief. The remaining
briefs were due on or about November 1, 1994. The State's response brief was due
on or about December 29, 1994.
 
  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
Department of Environmental Protection ("DEP"), Commissioner of the Department
of Health ("DOH"), and Lance Miller, Assistant Commissioner of DEP. The
multicount complaint alleges 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 and Resource Conservation
Recovery Act ("RCRA") violations at Liberty State Park. Under the
 
                                      B-47
<PAGE>   632
 
"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. The State intends to defend this suit 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 nineteen and one-half million dollars ($19,500,000) 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 State intends to vigorously defend this action in the
proper forum.
 
  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 and Energy
("DEPE"). A-901 refers to the Assembly bill number which was adopted in 1983 as
an amendment to the Solid Waste Management Act, establishing a requirement that
all persons and entities engaged in solid and hazardous waste activities in the
State of New Jersey 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 DEPE 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.

Van Kampen Merritt New Jersey Tax Free Income Fund

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

Notes to Financial Statements
December 31, 1994 

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

1. Significant Accounting Policies
Van Kampen Merritt New Jersey Tax Free Income Fund (the "Fund") was
organized as a subtrust of the Van Kampen Merritt Tax Free Fund, a
Massachusetts 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 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.


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 less than 60 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" and "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, 1994, 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.


D. Organizational Expenses and Initial Registration
Costs The Fund will reimburse Van Kampen American Capital
Distributors, Inc. or its affiliates ("VKAC") for costs incurred in
connection with the Fund's organization and initial registration in the
amount of $120,000. These costs are being amortized on a straight line
basis over the 60 month period ending July 29, 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 and initial
registration costs 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, 1994, the Fund had an accumulated capital loss 
carryforward for tax purposes of $11,885 which will expire on December 31, 2002.
Net realized gains or losses may differ for financial and tax reporting purposes
primarily as a result of post October 31 losses which are not recognized for tax
purposes until the first day of the following fiscal 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.


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:

Class B and C shares are offered without a front end sales charge, but are
subject to a contingent deferred sales charge (CDSC). The CDSC will be imposed
on most redemptions made within six years of the purchase for Class B and one
year of the purchase for Class C as detailed in the following schedule. The
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.

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 utilizes futures contracts to manage the portfolio's
effective maturity or duration.

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. 

The fluctuation in market value of the contracts is settled daily
through a cash margin account. Realized gains and losses are recognized
when the contracts are closed or expire.

Transactions in futures contracts, each with a par value of $100,000,
for the period ended December 31, 1994, were as follows:

6. Distribution and Service Plans
The Fund and its shareholders have adopted a distribution plan (the 
"Distribution Plan") pursuant to Rule 12b-1 under the Investment Company Act of
1940 and a service plan (the "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 .30% of Class A shares and 1.00% each of
Class B and Class C shares are accrued daily. Included in these fees for the
period ended December 31, 1994, are payments to VKAC of approximately $15,200.

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 believed by the Fund's investment adviser to be of
comparable quality, which involve special risk considerations. 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

Sales Arrangements") which may be purchased at a price equal to their net asset

contingent deferred basis (Class A Share accounts over $1 million, "Class B

the investor expects to hold the shares and other circumstances. See "Purchasing
Shares of the Fund."

                               PROSPECTUS SUMMARY
- --------------------------------------------------------------------------------
 
  The following summary is qualified in its entirety by reference to the more
detailed information included elsewhere in this Prospectus and the Statement of
Additional Information.
 
THE FUND  Van Kampen Merritt New York Tax Free Income Fund (the "Fund") is a
non-diversified mutual fund, organized as a separate sub-trust of Van Kampen
Merritt Tax Free Fund.
 
INVESTMENT OBJECTIVE AND POLICIES  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. 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."
 
PURCHASING SHARES OF THE FUND  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 with respect to each class is $1,000.
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 "Purchasing Shares of the Fund."
 
   
INVESTMENT ADVISER  Van Kampen American Capital Investment Advisory Corp. (the
"Adviser") is the investment adviser for the Fund. See "Investment Advisory
Services."
    
 
                                        4
<PAGE>   646
 
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."

(1) The Adviser agreed to waive a portion of its "Management Fees" during the
    Fund's last fiscal year. Absent the Adviser's waiver of its fee and
    assumption of a portion of the expenses of the Fund, the "Management Fees"
    would have been 0.60% for each class of shares and the "Total" would have
    been 2.73% for Class A Shares, 3.42% for Class B Shares and 3.42% 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. See "The
    Distribution and Service Plans."

  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 "Investment Advisory
Services" and "The Distribution and Service Plans."

THE FUND
- --------------------------------------------------------------------------------
 
  Van Kampen Merritt New York Tax Free Income Fund (the "Fund") is a
non-diversified, separate sub-trust of Van Kampen Merritt Tax Free Fund (the
"Trust"), an open-end management investment company, commonly known as a "mutual
fund," organized as a Massachusetts 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 "Investment
Company Act"). The Fund is designed for investors who are residents of New York
for tax purposes. 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 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
 
                                        9
<PAGE>   651
 
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 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
 
                                       10
<PAGE>   652
 
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.
- --------------------------------------------------------------------------------
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 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
 
                                       11
<PAGE>   653
 
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 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
 
                                       12
<PAGE>   654
 
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.
 
  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
 
                                       13
<PAGE>   655
 
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,
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
 
                                       14
<PAGE>   656
 
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, 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 high-grade municipal portfolio 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
 
                                       15
<PAGE>   657
 
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 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 Investment Company Act. See
"Investment Policies and Restrictions" in the Statement of Additional
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
 
                                       16
<PAGE>   658
 
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 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.
 
                                       17
<PAGE>   659
 
  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 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.

PURCHASING SHARES OF THE FUND
- --------------------------------------------------------------------------------
 
  The Fund currently offers three classes of shares to the public through Van
Kampen American Capital Distributors, Inc., (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") who are acting as securities dealers
("dealers") and through NASD members or eligible non-NASD members acting as
brokers or agents for investors ("brokers"). The Fund reserves the right to
suspend or terminate the public offering of its shares at any time and without
prior notice.
 
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 fees with respect to each class of shares that may be incurred over
the anticipated duration of their investment in the Fund.
 
  The Fund currently 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
 
                                       18
<PAGE>   660
 
   
basis (Class A Share accounts over $1 million, "Class B Shares" and "Class C
Shares"). Class A Share accounts over $1,000,000 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 $1,000.
The minimum subsequent investment with respect to each class of shares is $100.
It is presently the policy of the Distributor not to accept any order for Class
B Shares or Class C Shares in an amount of $1,000,000 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). Investors who intend to hold their shares for a
significantly long time may not wish to continue to bear the ongoing
distribution and service expenses of Class C Shares which, in the aggregate,
eventually would exceed the aggregate amount of the initial sales charge and
distribution and service related expenses applicable to Class A Shares,
irrespective of the fact that a CDSC would eventually not apply to a redemption
of such Class C shares.
 
  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. Only the Class B Shares are subject to
a conversion feature (discussed below). Generally, a class of shares subject to
a higher ongoing distribution fee, service fee or, where applicable, the
conversion feature will have a higher expense ratio and pay lower dividends than
a class of shares subject to a lower
 
                                       19
<PAGE>   661
 
ongoing distribution fee 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 "Net Asset Value."
 
  The administrative expenses that may be allocated to a specific class of
shares may consist of (i) transfer agency 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 that shall be approved by the SEC pursuant to
an amended exemptive order. 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 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
securities 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. See "Net Asset
Value."
 
  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
 
                                       20
<PAGE>   662
 
   
conditions, for certain favorable distribution arrangements for shares of the
Fund in its discretion may from time to time, pursuant to objective criteria
established by it, pay fees to 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. 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. In addition, the Distributor may, from time to time, sponsor
sales contests with respect to sales of the Fund's Class A Shares and Class B
Shares pursuant to which brokers, dealers and financial intermediaries may
receive additional compensation of up to 2% of sales in such shares. In
connection therewith, the Distributor may consider combining the sales of shares
made by such brokers, dealers and financial intermediaries of certain funds in
The Van Kampen Merritt Family of Funds. In addition, 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. In addition, the Distributor is sponsoring a sales contest for
INVEST Financial Corporation ("INVEST") relating to the Fund and other funds
distributed by the Distributor, pursuant to which the Distributor may provide an
INVEST broker an award valued up to $750.00 for sales of such funds during the
period April 1, 1995, through May 31, 1995. Such payments are made by the
Distributor out of its own assets, and not out of the assets of the Fund. These
programs will not change the price an investor pays for shares or the amount
that the Fund will receive from such sale.
    
 
INITIAL SALES CHARGE ALTERNATIVE--CLASS A SHARES
 
  The public offering price of Class A Shares for purchasers choosing the
initial sales charge alternative 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 an 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
 
                                       21
<PAGE>   663
 
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.

* No sales charge is payable at the time of purchase on investments of
  $1,000,000 or more, although for such investments the Fund imposes a
  contingent deferred sales charge 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 million, plus 0.20% on the next $2 million and
  0.08% on the excess over $5 million. See "Purchasing Shares Of The
  Fund--Deferred Sales Charge Alternatives" for additional information with
  respect to contingent deferred sales charges.
    
 
  QUANTITY DISCOUNTS. Purchasers of Class A Shares may be entitled to reduced
initial sales charges through a combination of investments, rights of
accumulation or a Letter of Intent (even if an investor is not making an
investment of a size that normally would qualify for a quantity discount).
Investors, or their broker, dealer or financial intermediary, 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.
 
  For purposes of determining whether a purchase qualifies for a reduced initial
sales charge, the term "any person" is defined as any one of the following:
 
   (i) an individual, their spouse and children under the age of 21, trust or
       custodial accounts established for any of their sole benefit(s) and any
       corporation, partnership or sole proprietorship which is 100% owned,
       either alone or in combination, by any of the foregoing; or
 
  (ii) a trustee or other fiduciary purchasing for a single trust estate
       (including a pension, profit-sharing or other employee benefit trust
       created pursuant to a plan qualified under Section 401 of the Internal
       Revenue Code, as amended); or
 
 (iii) a "company" as defined in Section 2(a)(8) of the Investment Company Act.

("ISC Shares"), which are made at any one time by "any person" may be combined
to receive a quantity discount.
 
  2. Rights of Accumulation. Under the rights of accumulation, in determining
the sales charge to be paid for a current purchase of Class A Shares, "any
person" may combine their current purchase with the current public offering
price of Class A Shares of the Fund or ISC Shares, which are owned by such
person. If the account an investor is combining for rights of accumulation
differs from the account into which the investor's current purchase is placed,
the investor must indicate to the Transfer Agent the account number (and, if
applicable, fund name) of such other account.
 
  3. Letter of Intent. Purchasers of Class A Shares may qualify immediately for
a reduced sales charge by stating their intention to purchase an amount of Class
A Shares, during a 13 month period, that would qualify the investor for a
reduced sales charge. An investor may do this by signing a nonbinding Letter of
Intent, which may be signed at any time within 90 days after the first
investment to be included under the Letter of Intent. Class A Shares purchased
under the "Rights of Accumulation" described above (including investments in ISC
Shares) may be, at the time of the signing of the Letter of Intent, applied
towards completion of an investor's Letter of Intent. In addition, if an
investor's broker, dealer or financial intermediary and the Distributor agree to
refund the appropriate portion of their respective concessions to the Fund, the
sales charge on an investor's previous purchases made within 90 days may be
adjusted to the reduced sales charge under the Letter of Intent, and the
refunded concession will be used to purchase shares of the Fund at the public
offering price next determined after receipt of such monies. Each investment
made after signing the Letter of Intent will be entitled to the initial sales
charge applicable to the total investment indicated in the Letter of Intent. If
an investor does not complete the necessary purchases under the Letter of Intent
within 13 months from the date of the first purchase included thereunder, the
sales charge will be adjusted upward, corresponding to the amount actually
purchased.
 
  When an investor signs a Letter of Intent, Class A Shares of the Fund
purchased with a value of 5% of the amount specified in the Letter of Intent
will be restricted; that is, these Class A Shares cannot be sold or redeemed
until the Letter of Intent is satisfied or the additional sales charges have
been paid. If the total purchases made under the Letter of Intent, less
redemptions, equal or exceed the amount specified in the Letter of Intent, these
Class A Shares will no longer be restricted. If the total purchases, less
redemptions, exceed the amount so specified, and qualify an investor for a
further quantity discount, the Distributor and the investor's securities broker,
dealer or financial intermediary will, upon request, remit their respective
portions of the sales concession and with that amount, purchase additional Class
A Shares of the Fund for the investor's account at the next determined public
offering price. If an investor does not complete the necessary purchases under
the Letter of Intent, the sales charges will be adjusted upward and if, after
written notice, the investor does not pay the increased sales charge, sufficient
restricted Class A Shares will be redeemed to pay such charge.
 
  OTHER PURCHASE PROGRAMS. Purchasers of Class A Shares may be entitled to
reduced initial sales charges in connection with unit trust reinvestment
programs and purchases by
 
                                       23
<PAGE>   665
 
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.
 
  1. Unit Trust Reinvestment Programs. The Fund permits unitholders of New York
unit investment trusts to reinvest distributions from such trusts in Class A
Shares of the Fund at net asset value.
 
  The Fund permits unitholders of unit investment trusts to reinvest
distributions from such trusts in Class A Shares of the Fund and other ISC
Shares with no minimum initial or subsequent investment requirement, and with a
lower sales charge 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 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 dealer or broker, 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 securities broker or dealer 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 the Fund's transfer agent with
appropriate backup data for each participating investor in a computerized format
fully compatible with the transfer agent's 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.
    
 
2. NAV Purchase Options
 
  The classes of investors entitled to purchase shares of the Fund at net asset
value are as follows:
 
 (a) Current or retired Trustees/Directors of funds advised by Van Kampen
     American Capital Investment Advisory Corp., Van Kampen American Capital
     Asset Management, Inc. or John Govett & Co. Limited and such persons'
     families and their beneficial accounts. The term "families" includes a
     person's spouse, children and grandchildren, parents, and a person's
     spouse's parents.
 
 (b) Current or retired directors, officers and employees of VK/AC Holdings,
     Inc. and any of its subsidiaries, Clayton, Dubilier & Rice, Inc., employees
     of an investment
 
                                       24
<PAGE>   666
 
     subadviser to any such fund or an affiliate of such subadviser; and such
     persons' families and their beneficial accounts.
 
 (c) Directors, officers, employees and registered representatives of financial
     institutions that have a selling agreement with the Distributor and their
     spouses and minor children 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.
 
   
 (d) 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 the Fund alone, or in any combination of
     Class A Shares of the Fund and ISC Shares of other funds distributed by the
     Distributor as described herein under "Purchasing Shares Of The
     Fund--Initial Sales Charge Alternative--Quantity Discounts," during the 13
     month period commencing with the first investment pursuant hereto equals at
     least $1 million. The Distributor may pay such entities through which
     purchases are made an amount up to 0.50% of the amount invested, over a
     twelve month period following such transaction.
    
 
 (e) Trustees and other fiduciaries purchasing shares for retirement plans of
     organizations with retirement plan assets of $10 million or more. The
     Distributor may pay commissions of up to 1% for such purchases.
 
 (f) Accounts as to which a selling firm charges an account management fee
     ("wrap accounts"), provided the selling firm has executed a supplemental
     agreement to their existing selling agreement with the Distributor.
 
 (g) 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.
 
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 other financial
intermediaries which percentage rate will be equal to (i) 1.00% with respect to
Class A Shares in an amount of $1 million or more; (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. Sales compensation with
respect to Class A Shares subject to a CDSC is set forth under "Purchasing
Shares of the Fund-- Initial Sales Charge Alternative".
 
                                       25
<PAGE>   667
 
  CDSC Shares redeemed within a specified period of time generally will be
subject to a contingent deferred sales charge at the rates set forth below. The
amount of the contingent deferred sales charge 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 contingent
deferred sales charge 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 contingent deferred sales charge 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 contingent deferred sales charge
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. Investors
should understand that the purpose of the contingent deferred sales charge and
the distribution fee with respect to a class of CDSC Shares is the same as the
initial sales charge and the distribution fee with respect to Class A Shares.
 
  In determining whether a contingent deferred sales charge 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 contingent deferred sales charge 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, if any, and fourth of CDSC Shares held
longest during the period of time that a contingent deferred sales charge 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).
 
  The contingent deferred sales charge is waived (i) on a redemption of shares
following the death of a shareholder, or (ii) to the extent that the redemption
represents a minimum
 
                                       26
<PAGE>   668
 
required distribution from an IRA or other retirement plan to a shareholder who
has attained the age of 70 1/2.
 
   
  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 $1,000,000 or more,
although for such investments the Fund imposes a contingent deferred sales
charge 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 million, plus 0.20% on the next $2 million and 0.08% on the
excess over $5 million.
    
 
  CLASS B SHARES. Class B Shares redeemed within seven years of purchase
generally will be subject to a contingent deferred sales charge at the rates set
forth below, charged as a percentage of the dollar amount subject thereto:

  The contingent deferred sales charge generally is waived on redemptions of
Class B Shares made pursuant to the Systematic Withdrawal Program. See
"Shareholder Programs--Systematic Withdrawal Program."
 
  CLASS C SHARES. Class C Shares redeemed within the first twelve months of
purchase generally will be subject to a contingent deferred sales charge 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. Seven years after the end of the month in which a
shareholder's order to purchase a Class B Share of the Fund was accepted, such
Class B Share automatically will convert to a Class A Share and will no longer
be subject to the higher aggregate distribution and service fees. The purpose of
the conversion feature is to relieve the holders of Class B Shares that have
been outstanding for a period of time sufficient for the Distributor to have
been compensated for distribution expenses related to the Class B Shares from
most of the burden of such distribution-related expenses. The Fund does not
expect to issue any stock certificates upon conversion.
 
  For purposes of conversion of Class A Shares, Class B Shares purchased through
the reinvestment of dividends and distributions paid in respect of Class B
Shares in a shareholder's account will be considered to be held in a separate
sub-account. Each time
 
                                       27
<PAGE>   669
 
any Class B Shares in the shareholder's account (other than those in the
sub-account) convert to Class A Shares, an equal pro rata portion of the Class B
Shares in the sub-account also will convert to Class A Shares. The holding
period applicable to a Class B Share acquired through the use of the exchange
privilege (discussed below) shall be the holding period applicable to a Class B
Share of such Fund acquired other than through use of the exchange privilege.
For purposes of calculating the holding period applicable to a Class B Share of
the Fund prior to conversion, a Class B Share of the Fund issued in connection
with an exercise of the exchange privilege, or a series of exchanges, shall be
deemed to have been issued on the date on which the investor's order to purchase
the exchanged Class B Share was accepted or, in the case of a series of
exchanges, when the investor's order to purchase the original Class B Share was
accepted.
 
  The conversion of Class B 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 services fee and transfer agency costs
with respect to Class B 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 Class B
Shares does not constitute a taxable event under federal income tax law. The
conversion of Class B Shares to Class A Shares may be suspended if such an
opinion is no longer available. In that event, no further conversions of Class B
Shares would occur, and Class B Shares might continue to be subject to the
higher aggregate distribution and service fees for an indefinite period.
 
- --------------------------------------------------------------------------------
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 the Fund's transfer agent receives payments for such shares.
However, shares become entitled to dividends on the day the Fund's transfer
agent receives payment for the
 
                                       28
<PAGE>   670
 
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 information under the "Distributions" section of the
Account Application bound in this Prospectus or available from State Street Bank
and Trust Company, c/o National Financial Data Services, Van Kampen Merritt
Funds, P.O. Box 419001, Kansas City, MO 64141-6001 (the "Transfer Agent"). After
the Transfer Agent 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 to the Transfer Agent. This election may be made by telephone by
calling 1-800-341-2911 or in writing to the Transfer Agent. For inquiries
through Telecommunications Device for the Deaf (TDD), dial 1-880-772-8889,
during the hours of 7:30 a.m. and 4:00 p.m. Central Standard Time. If a
shareholder elects to change the method of distribution, such change will be
effective only with regard to distributions for which the record date is seven
or more business days after the Transfer Agent has received the request. CDSC
Shares received as reinvested dividends are subject to a 12b-1 fee, a portion of
which may indirectly pay for the initial sales commission incurred on behalf of
the investor.
 
- --------------------------------------------------------------------------------
REDEMPTION OF SHARES
- --------------------------------------------------------------------------------
 
  WRITTEN REDEMPTION REQUEST. Shareholders may sell shares without charge (other
than, with respect to the CDSC Shares, any applicable contingent deferred sales
charge) at any time by mailing a written redemption request in proper form to
the Transfer Agent. This request should be sent to State Street Bank and Trust
Company, c/o National Financial Data Services, Van Kampen Merritt Funds, P.O.
Box 419001, Kansas City, MO 64141-6001. The request should indicate the number
of shares to be redeemed of a particular fund and the class designations of such
shares, identify the account number and be signed exactly as the shares are
registered. If the amount being redeemed is in excess of $50,000 or if the
redemption proceeds will be sent to an address other than the address of record,
the signature(s) must be guaranteed by a member firm of a principal stock
exchange, a commercial bank or trust company which is a member of the Federal
Deposit Insurance Corporation, a credit union or a savings association. The
guarantee must state the words "Signature Guaranteed" along with the name of the
granting institution. Shareholders should verify with the institution that it is
an eligible guarantor prior to signing. A guarantee from a notary public is not
acceptable. If certificates are held for the shares being redeemed, such
certificates must be sent and endorsed for transfer or accompanied by an
endorsed stock power. Share certificates should be sent by registered mail to
National Financial Data Services, 1004 Baltimore Avenue, Dwight Building, Sixth
Floor,
 
                                       29
<PAGE>   671
 
Kansas City, MO 64105-1807. Shareholders will receive the net asset value per
share next computed after the Transfer Agent receives the redemption request and
certificates (if any) in proper form. Any applicable contingent deferred sales
charge with respect to CDSC Shares redeemed will be deducted from the redemption
proceeds prior to transmittal of such proceeds to the shareholder.
 
   
  TELEPHONE REDEMPTIONS. Shareholders may sell shares by calling the Fund at
1-800-341-2911 before 3:00 p.m. Central Standard Time to request a redemption by
the Fund. For inquiries through Telecommunications Device for the Deaf (TDD),
dial 1-800-772-8889, during the hours of 7:30 a.m. to 3:00 p.m. Central Standard
Time. There is a $500 minimum and a $1,000,000 maximum per request if the
redemption proceeds are to be mailed to the shareholder. If the redemption
proceeds are to be wired to a bank there is a minimum of $5,000 and a $1,000,000
maximum per request. Prior to redeeming shares by telephone the "Expedited
Telephone Redemption" section of either the Account Application or Expedited
Telephone Redemption and Exchange Request Form (the "Authorization") must be
completed and on file with the Transfer Agent. The signature(s) on the
Authorization must be guaranteed by a member firm of a principal stock exchange,
a commercial bank or trust company which is a member of the Federal Deposit
Insurance Corporation, a credit union or a savings association unless the
Authorization is completed at the time an account is originally established. The
guarantee must state the words "Signature Guaranteed" along with the name of the
granting institution. Shareholders should verify with the institution that it is
an eligible guarantor prior to signing. A guarantee from a notary public is not
acceptable. A redemption requested by telephone will be processed at the net
asset value next determined after receipt of the request. Any applicable
contingent deferred sales charge with respect to CDSC Shares redeemed will be
deducted from the redemption proceeds prior to transmittal of such proceeds to
the shareholder. The proceeds would then be made payable to the registered
shareowner(s) and mailed to the address registered on the account or wired to a
bank, as requested on the Authorizations. Shareholders cannot redeem shares by
telephone if stock certificates are held for those shares. This service is not
available with respect to shares held in an Individual Retirement Account for
which State Street Bank and Trust Company acts as custodian. In addition, this
service is not available with respect to shares purchased by check until 15 days
after purchase.
    
 
   
  By establishing the telephone redemption service, a shareholder authorizes the
Fund or the Transfer Agent to act upon the instructions of any person by
telephone to redeem shares for any account for which such service has been
authorized. The Fund, the Distributor, the Transfer Agent and National Financial
Data Services, Inc. ("NFDS") employ procedures reasonably believed to confirm
that instructions communicated by telephone are genuine. Such procedures include
requiring a person attempting to redeem shares by telephone to provide, on a
recorded line, the name on the account, a social security number or tax
identification number and such additional information as may be included in the
Authorization. In addition, a shareholder agrees that none of the Fund, the
Distributor, the Transfer Agent or National Financial Data Services will be
liable for any loss, liability, cost or expense arising out of any request,
including any fraudulent or unauthorized request. This service may be amended or
terminated at any time by the
    
 
                                       30
<PAGE>   672
 
Transfer Agent or the Fund. If a shareholder is unable to reach the Fund by
telephone, he or she may redeem shares pursuant to the procedures set forth
above under the caption "Written Redemption Request." During periods of extreme
economic or market changes, it may be difficult for investors to reach the Fund
by telephone and to effect telephone redemptions.
 
  REDEMPTION THROUGH DEALERS. Shareholders may sell shares (whether in
certificate or book-entry form) through their securities dealer, who will
telephone the request to the Distributor. Shareholders will receive the net
asset value next determined after such shareholder places the sell order. Any
applicable contingent deferred sales charge with respect to CDSC Shares redeemed
will be deducted from the redemption proceeds prior to transmittal of such
proceeds to the shareholder. It is the responsibility of the shareholder's
broker, dealer or financial intermediary to transmit the redemption order to the
Distributor. Because the Fund generally will determine net asset value once each
business day as of the close of business, sell orders placed through a
shareholder'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 shareholder's order to be fulfilled on the basis of the
net asset value to be determined that day. Any change in the redemption price
due to the failure of the Distributor to receive a sell order prior to such time
must be settled between the shareholder and the broker, dealer or financial
intermediary submitting the order. The Fund does not charge for this transaction
(other than any applicable contingent deferred sales charge). Shareholders must
submit a written redemption request in proper form to their securities dealer
within five business days after calling the dealer with the sell order. The
request should indicate the number of shares to be redeemed and the class
designation of such shares, identify the account number and the order or
confirmation number assigned to the trade and be signed by the shareholder
exactly as the shares are registered. If the amount of the redemption exceeds
$50,000 or if the redemption proceeds will be sent to an address other than the
address of record, signature(s) must be guaranteed by a member firm of a
principal stock exchange, a commercial bank or trust company which is a member
of the Federal Deposit Insurance Corporation, a credit union or a savings
association. The guarantee must state the words "Signature Guaranteed" along
with the name of the granting institution. Shareholders should verify with the
institution that it is an eligible guarantor prior to signing. A guarantee from
a notary public is not acceptable. If certificates are held for the shares being
redeemed, such certificates must be sent endorsed for transfer or accompanied by
an endorsed stock power. Certificates should be sent by registered mail to State
Street Bank and Trust Company, c/o National Financial Data Services, Van Kampen
Merritt Funds, 1004 Baltimore Avenue, Dwight Building, Sixth Floor, Kansas City,
MO 64105-1807. Shareholders whose shares are held in an Individual Retirement
Account ("IRA") for which State Street Bank and Trust Company acts as custodian
may not sell their shares through their securities dealers.
 
   
  REDEMPTION UPON DISABILITY. The Fund will waive the CDSC on Class B Share
redemptions following the disability of a Class B shareholder. An individual
will be considered disabled for this purpose if he or she meets the definitions
thereof in Section 72(m)(7) of the Internal Revenue Code (the "Code"), which in
pertinent part
    
 
                                       31
<PAGE>   673
 
   
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 Fund will
require satisfactory proof of disability before it determines to waive the CDSC
on Class B Shares.
    
 
   
  In cases of disability, the CDSC on Class B 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 applies to a total or partial redemption, but only to redemptions of
shares held at the time of the initial determination of disability.
    
 
  GENERAL. Whether shares are redeemed by the Fund or sold through a securities
dealer, a check for the proceeds (net of any required tax withholding and, with
respect to CDSC Shares, any applicable contingent deferred sales charge)
ordinarily will be mailed to shareholders or their dealer, as the case may be,
within seven calendar days after a redemption request or repurchase order and
share certificates (if any) are received in proper form as set forth above. Wire
transfers from the Fund of redemption proceeds, in the manner described above,
ordinarily will be transmitted to the shareholder within one business day. If
any shares are redeemed or repurchased shortly after purchase, the Fund will not
mail the proceeds until checks received for the purchase of shares have cleared,
which may take 10 days or more. The proceeds, of course, may be more or less
than the cost of the shares.
 
  The right of redemption or resale to the Fund may be suspended or the date of
payment postponed during any period when the New York Stock Exchange is closed
(other than customary weekend and holiday closings), when an emergency exists as
defined by rules and regulations of the SEC, or during any period when the SEC
has by order permitted such suspension or postponement.
 
  The Fund reserves the right to redeem any investment if the value of an
account falls below $500. Before the Fund makes such redemption it will provide
the shareholder with written notice and 30 days in which to make an additional
investment sufficient to increase the value of the account to at least $500.
- --------------------------------------------------------------------------------
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
 
                                       32
<PAGE>   674
 
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 sub-trust. 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.

  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 sub-trust. Subject to their authority, the Adviser and the respective
officers of the Fund will supervise and implement the Fund's investment
activities and will be responsible for overall management of the Fund's business
affairs. The Adviser may, in its sole discretion, determine to waive temporarily
all or a portion of its fee or it may discontinue this practice without notice
to shareholders. Without such waiver, the Fund would pay the Adviser a fee equal
to a percentage of the average daily net assets of the Fund as follows:

  Under its investment advisory agreement, 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 Investment Company Act, of the Adviser, Van Kampen American
Capital Distributors, Inc. or Van Kampen American Capital, Inc.), the charges
and expenses of independent accountants, legal counsel, any transfer 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
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 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 trustees/directors, officers and employees to buy and sell
securities for their personal accounts subject to preclearance and other
procedures designed to prevent conflicts of interest.
 
  PORTFOLIO MANAGEMENT.  David C. Johnson, a First 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 for the last five years. Robert S.
Waas, an Assistant Vice President of the Adviser, is primarily responsible for
the day-to-day management of the Fund's portfolio. Mr. Waas has been employed by
the Adviser since July, 1992. Prior to 1992 Mr. Waas managed tax-exempt assets
for other registered investment companies.
 
- --------------------------------------------------------------------------------
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
 
                                       34
<PAGE>   676
 
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,
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.
 
- --------------------------------------------------------------------------------
THE 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 Investment
Company 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,
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, NASD
members or eligible non-members who are acting as brokers or agents and similar
agreements between the Fund and banks who are acting as brokers (collectively,
"Selling Agreements") that may provide for their customers or clients certain
services or assistance. Brokers, dealers and banks that have entered into
Selling Agreements with the Distributor and sell shares of the Fund are referred
to herein as "financial intermediaries."
 
                                       35
<PAGE>   677
 
  CLASS A SHARES. The Fund may spend an aggregate amount up to 0.30% 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 financial intermediaries and in connection with the
maintenance of such shareholders' accounts. The Fund pays the Distributor the
lesser of the balance of the 0.30% not paid to such 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 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 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
financial intermediary's customers. The Fund pays the Distributor the lesser of
the balance of 0.75% not paid to such 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 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 contingent deferred sales charge. 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
 
                                       36
<PAGE>   678
 
   
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. The Fund will disclose in its
prospectus from time to time the then current amount of any such unreimbursed
expenses with respect to each class of CDSC Shares expressed as a dollar amount
and as a percent of the Fund's total net assets. As of December 31, 1994, there
were $11,901 and $1,901 of unreimbursed distribution related expenses with
respect to Class B Shares and Class C Shares, respectively, representing 0.11%
and 0.02% of the Fund's total net assets. 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 contingent deferred sales charges.
    
 
  Because the Fund is a sub-trust of the Trust, amounts paid to the Distributor
as reimbursement for expenses of one sub-trust of the Trust may indirectly
benefit the other funds which are sub-trusts 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 contingent deferred sales charge
applicable to a particular class of CDSC Shares to defray distribution related
expenses attributable to any other class of CDSC 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.
 
- --------------------------------------------------------------------------------
TAX STATUS
- --------------------------------------------------------------------------------
 
  The following New York State, New York City and federal income tax discussion
is based on the advice of Skadden, Arps, Slate, Meagher & Flom, and reflects
applicable income tax laws, as of the date of this Prospectus.
 
  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%,
    
 
                                       37
<PAGE>   679
 
   
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 intends to qualify each year and to elect to
be treated as a regulated investment company under Subchapter M of the Internal
Revenue Code of 1986, as amended (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 gains, but not net capital gain, which is the
excess of net 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 net
investment 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. Similarly, the Fund will not be subject to federal
income tax on any net capital gain distributed to its shareholders. As a
sub-trust of a Massachusetts business trust, the Fund will not be subject to any
excise or income taxes in Massachusetts as long as it qualifies as a regulated
investment company for federal income tax purposes.
 
   
  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 (which does not
include tax-exempt income) for such year and at least 98% of its net capital
gains (the latter of which is generally computed on the basis of the one-year
period ending on October 31 of such year), plus any required distribution
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 was
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
 
                                       38
<PAGE>   680
 
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 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 closed out), 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.
 
  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 avoid income and excise taxes, the Fund may have to
dispose of securities that it would otherwise have continued to hold.
 
  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 gross income be derived from the disposition of securities
held for less than three months.
 
  DISTRIBUTIONS. If the Fund qualifies as a regulated investment company and
satisfies the 90% distribution requirement, and if, at the close of each quarter
of the Fund's taxable year, at least 50% of the total value of the Fund's assets
consists of obligations the interest on which is exempt from federal income tax
("tax-exempt obligations"), the Fund will be qualified to pay exempt-interest
dividends to its shareholders to the extent of its tax-exempt interest income
(less expenses applicable thereto). Exempt-interest dividends are excludable
from a shareholder's gross income for federal income tax purposes, but may be
taxable distributions for state, local and other tax purposes. Exempt-interest
dividends are included, however, 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. Interest expense with respect to
indebtedness incurred or continued by a shareholder to purchase or carry shares
of the Fund is not deductible to the extent that such interest relates to
exempt-interest dividends received from the Fund.
 
  Distributions of the Fund's investment company taxable income (which does not
include tax-exempt interest income) are taxable to shareholders as ordinary
income whether received in shares or in cash. Shareholders who receive
distributions in the form
 
                                       39
<PAGE>   681
 
of additional shares will have a basis for federal income tax purposes in each
such share equal to the value thereof on the reinvestment date. Distributions of
the Fund's net capital gain ("capital gain dividends"), if any, are taxable to
shareholders at the rates applicable to long-term capital gains regardless of
the length of time shares of the Fund have been held by such shareholders. All
or a portion of the Fund's gain from the sale or redemption of tax-exempt
obligations purchased at a market discount will be treated as ordinary income
rather than capital gain. 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 shareholders (assuming such shares are held as a capital asset). It is not
expected that any portion of the distributions from the Fund will be eligible
for the dividends received deduction for corporations. The Fund will inform
shareholders of the source and tax status of distributions promptly after the
close of each calendar year.
 
  Exempt-interest dividends allocable to interest received by the Fund on
certain "private activity" obligations issued after August 7, 1986 will be
treated as interest on such obligations and thus will give rise to an item of
tax preference that will increase a shareholder's alternative minimum taxable
income. In addition, for corporations, alternative minimum taxable income will
be increased by a percentage of the amount by which a measure of income that
includes interest on tax-exempt obligations exceeds the amount otherwise
determined to be the alternative minimum taxable income. Accordingly, investment
in the Fund may cause such shareholders to be subject to (or result in an
increased liability under) the alternative minimum tax.
 
  Exempt-interest dividends will not be tax-exempt to the extent made to any
shareholder who is a "substantial user" of the facilities financed by tax-exempt
obligations held by the Fund or "related persons" of such substantial users.
 
  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 a month and paid in 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 is actually made.
 
  The Fund is required, in certain circumstances, to withhold 31% of taxable
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. Redemption or sale of shares of the Fund will be a taxable
transaction for federal income tax purposes. Redeeming shareholders will
generally recognize gain or loss in an amount equal to the difference between
their basis in such redeemed shares of
 
                                       40
<PAGE>   682
 
the Fund 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 generally be long-term
if such shares have been held for more than one year. Any loss realized on a
taxable disposition of shares held for six months or less will be disallowed to
the extent of any exempt-interest dividends received with respect to such
shares. If such loss is not entirely disallowed, it will be treated as a
long-term capital loss to the extent of any capital gain 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 and New York income tax discussion set forth above is
for general information only. Prospective investors should consult their tax
advisers regarding the specific federal and New York tax consequences of holding
and disposing of shares, as well as the effects of other state, local and
foreign tax laws and any proposed tax law changes. Also, see "Tax Status of the
Fund" in the Statement of Additional Information for further information.
- --------------------------------------------------------------------------------
SHAREHOLDER PROGRAMS
- --------------------------------------------------------------------------------
 
   
  SHARE CERTIFICATES.  As a rule, the Fund will not issue share certificates.
Upon written or telephone request to the Fund, however, 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. In addition, if such certificates are lost the shareholder must
write to State Street Bank and Trust Company, c/o National Financial Data
Services, P.O. Box 419001, Kansas City, MO 64141-6001, Attn: Van Kampen Merritt
Funds, requesting an "affidavit of loss" and to obtain a Surety Bond in a form
acceptable to the Transfer Agent. On the date the letter is received the
Transfer Agent will calculate no more than 2.00% of the net asset value of the
issued shares, and bill the party to whom the certificate was mailed.
    
 
   
  SYSTEMATIC WITHDRAWAL PROGRAM.  If a shareholder's Class A Share account or
Class B Share account is valued at $10,000 or more, such shareholder's dividends
are being reinvested, a requested dollar amount may be paid from such account to
any person monthly, quarterly, semiannually or annually. The minimum amount that
may be withdrawn each period is $50; withdrawals will be made on the seventh
business day of the month in which they are scheduled to occur. Depending upon
the size of the payments requested and the fluctuations in the net asset value
of the shares redeemed, redemptions for the purpose of making such payments may
reduce or even exhaust the amounts in such account. If an investor acquires
additional shares of the Fund after joining the Systematic Withdrawal Program,
the investor must inform the Fund if he or she wants the new shares to be
subject to the Systematic Withdrawal Program by telephoning the Fund at
1-800-341-2911.
    
 
   
  With respect to redemptions of Class B Shares made pursuant to the Systematic
Withdrawal Program, an investor may annually redeem up to 12% of the net asset
value of
    
 
                                       41
<PAGE>   683
 
   
the investor's initial investment in Class B Shares or, if the investor does not
join the program on the date of his or her initial investment, the net asset
value of the investor's Class B Shares on the date the investor elects to
participate in the Systematic Withdrawal Program. The Fund will waive the
contingent deferred sales charge applicable to Class B Shares redeemed pursuant
to the Fund's Systematic Withdrawal Program.
    
 
  It will ordinarily be disadvantageous to purchase shares (except through
reinvestment of distributions) while participating in a systematic withdrawal
program because a shareholder will be paying a sales charge, or will become
subject to a contingent deferred sales charge, in order to purchase shares at
the same time that shares are being redeemed upon which a sales charge may
already have been paid. Therefore, the Fund will not knowingly permit a
shareholder to make additional investments in shares of less than $5,000 if at
the same time such shareholder is making systematic withdrawals at a rate
greater than the distribution being paid on such shareholder's shares. The Fund
reserves the right to amend or terminate the systematic withdrawal program on
thirty days' notice, and a shareholder may withdraw from the program at any
time.
 
  EXCHANGE PRIVILEGE.  Any Class A Shares of the Fund which have been registered
in a shareholder's name for at least 15 days will be able to be exchanged for
ISC Shares of other Van Kampen Merritt mutual funds distributed by the
Distributor that offer an exchange privilege. Under the exchange privilege, the
Fund will offer to exchange its Class A Shares for ISC Shares on the basis of
relative net asset value per share. Any ISC Shares exchanged into the Fund that
have been charged a sales load lower than the sales load applicable to Class A
Shares of the Fund will be charged the applicable sales load differential upon
exchange. ISC Shares of the Van Kampen Merritt Money Market Fund and Van Kampen
Merritt Tax Free Money Fund which have not previously been charged a sales load
(except for shares purchased via the reinvestment option) will be charged the
applicable sales load upon exchange into the Fund.
 
  Class B Shareholders of the Fund may exchange their Class B Shares
("Outstanding Class B Shares") for Class B Shares of other Van Kampen Merritt
mutual funds sponsored by the Distributor ("New Class B Shares") on the basis of
relative net asset value per Class B Share, without the payment of any
contingent deferred sales charge that might otherwise be due on redemption of
the Outstanding Class B Shares. Class B Shares of a fund acquired through use of
the exchange privilege will be 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.
 
   
  Class C Shares of the Fund are exchangeable for Class C Shares of other Van
Kampen Merritt mutual funds distributed by the Distributor on the same terms set
forth in the preceding paragraph with respect to Class B Shares, except that
Class C Shares do not convert to Class A Shares. The exchange privilege with
respect to any Van Kampen Merritt money market fund sponsored by the Distributor
is not available for Class C Shareholders.
    
 
  In order to qualify for the exchange privilege, it is required that the shares
being exchanged have a net asset value of at least $1,000 (unless prior approval
has been
 
                                       42
<PAGE>   684
 
   
obtained from the Fund). Shareholders will be able to effect an exchange by
telephone by calling the Fund at 1-800-341-2911 prior to 3:00 p.m. Central
Standard Time. For inquiries through Telecommunications Device for the Deaf
(TDD), dial 1-800-772-8889, during the hours of 7:30 a.m. to 3:00 p.m. Central
Standard Time. The exchange will be processed at the net asset value next
determined after receipt of such request. By utilizing the telephone exchange
service, a shareholder authorizes the Fund or the Transfer Agent to act upon the
instructions of any person by telephone to exchange shares from any account for
which such service has been authorized to any identically registered account(s)
with any Van Kampen Merritt fund distributed by the Distributor that offers an
exchange privilege. In addition, a shareholder agrees that none of the Fund, the
Distributor, the Transfer Agent or National Financial Data Services ("NFDS")
will be liable for any loss, liability, cost or expense arising out of any
request, including any fraudulent request. The staff of the SEC currently is
reviewing its position with respect to such agreements. This service may be
amended or terminated at any time by the Transfer Agent or the Fund. If a
shareholder has certificates for any shares being exchanged, such certificates
must be surrendered prior to the exchange in the same manner as in redemption of
such shares. See "Redemption of Shares--Telephone Redemptions". Any shares
exchanged between the Fund and any of the other funds will begin earning
dividends on the next business day after the exchange is effected. 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.
    
 
  An exchange between Van Kampen Merritt funds pursuant to the exchange
privilege is treated as a sale for federal income tax purposes and, depending
upon the circumstances, a short- or long-term capital gain or loss may be
realized.
 
  The exchange privilege may be modified or terminated at any time, subject to
the requirement that the Fund give prominent notice thereof at least 60 days
prior to the effective date of the modification or termination in certain
circumstances. The Fund reserves the right to limit the number of times a
shareholder may exercise the exchange privilege.
 
  AUTOMATED MULTIPLE ACCOUNT SHAREHOLDER SERVICES (AMASS(SM)).
 
   
  1. 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
the Transfer Agent 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
    
 
                                       43
<PAGE>   685
 
proceeds of such redemption. Once enrolled in the ACH plan, a shareholder may
terminate participation at any time by writing the Transfer Agent.
 
  2. Automated Dividend Programs.  The Fund will, upon the election of a
shareholder, automatically invest distributions from a shareholder's account
directly into a shareholder's bank account.
 
   
  3. Dividend Diversification.  Monthly distributions and any net long-term
capital gain distributions to a shareholder's account may be invested in the
same class of shares of any other Van Kampen Merritt mutual fund distributed by
the Distributor at the then current net asset value, WITHOUT A SALES CHARGE,
upon election by a shareholder. This election may be made on the account
application bound in this Prospectus, by written notice to the Transfer Agent or
by calling the Fund directly at 1-800-341-2911, during the hours of 7:00 a.m. to
7:00 p.m. Central Standard Time. For inquiries through Telecommunications Device
for the Deaf (TDD), dial 1-800-772-8889. In order to qualify for this privilege,
a shareholder must have established an account in the other mutual fund prior to
electing this privilege. This privilege may be modified or terminated by the
Fund at any time.
    
 
  4. Easy Account Savings Enhancement Plan (EASE(SM)).  Once a shareholder has
opened an account with the minimum $1,000 investment, the automatic investment
option may be utilized to make regular electronic monthly investments of $100 or
more into such shareholder's account with the Fund. In order to utilize this
option, a shareholder must fill out and sign the appropriate section of the
application attached to this Prospectus or the EASE(SM) application which is
available from the Transfer Agent, the Fund, such shareholder's broker or dealer
or the Distributor. Once the Transfer Agent has received this application, such
shareholder's checking account at his or her designated local bank will be
debited each month in the amount authorized by such shareholder to purchase
shares of the Fund. Once enrolled in the EASE(SM) program, a shareholder may
change the monthly amount or terminate participation at any time by writing or
calling the Transfer Agent. Shareholders in the EASE(SM) program will receive a
confirmation of these transactions from the Fund monthly, and their regular bank
account statements will show the debit transaction each month.
 
  By electing to utilize any of the foregoing services, a shareholder authorizes
the Transfer Agent or its agent to act upon the instructions indicated in the
appropriate section of the Application in performing such services by either
withdrawing funds for deposit in the Fund pursuant to the EASE(SM) Plan or
depositing distributions and redemptions in the bank account indicated by the
voided check or deposit slip accompanying the shareholder's election or by
depositing the shareholder's distributions in the Van Kampen Merritt fund
account indicated. A shareholder also agrees that neither the Fund, the
Distributor, the Transfer Agent nor NFDS will be liable for any loss, liability,
cost or expense arising out of any request, including any fraudulent request.
This service may be amended or terminated at any time by the Transfer Agent or
by the Fund.
 
  REINSTATEMENT PRIVILEGE.  A shareholder who has redeemed Class A Shares or
Class B Shares may, within 120 days, repurchase Class A Shares of the Fund, or
shares of other Van Kampen Merritt mutual funds distributed by the Distributor,
in an amount of at least
 
                                       44
<PAGE>   686
 
$500 and not exceeding the redemption proceeds received, at a purchase price
equal to the net asset value next determined after the reinstatement request is
received by the Transfer Agent or the Distributor. A Class C Shareholder who has
redeemed shares of the Fund may repurchase Class C Shares of the Fund, or shares
of other Van Kampen Merritt mutual funds distributed by the Distributor with
credit given for any contingent deferred sales charge paid upon such redemption.
 
- --------------------------------------------------------------------------------
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., Business Week, Forbes or other industry 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.
 
  Please consult the Statement of Additional Information for more information
regarding the Fund's performance.

SHAREHOLDER SERVICES
- --------------------------------------------------------------------------------
 
  State Street Bank and Trust Company, c/o National Financial Data Services,
P.O. Box 419001, Kansas City, MO 64141-6001, transfer agent for the Fund,
performs bookkeeping, data processing and administrative services related to the
maintenance of shareholder accounts. When an initial investment is made in the
Fund, an account will be opened for each shareholder on the Fund's books and
shareholders will receive a confirmation of the opening of the account.
Shareholders will receive monthly statements giving details of all activity in
their account(s) and will also receive a statement whenever an investment or
withdrawal is made in or from their account. Information for federal income tax
purposes will be provided at the end of the year. Such statements will present
separately information with respect to each class of the Fund's shares. It is
expected that the transfer agency costs attributable to the Class B Shares and
Class C Shares will be higher than the transfer agency costs attributable to the
Class A Shares.
 
- --------------------------------------------------------------------------------
DESCRIPTION OF SHARES OF THE FUND
- --------------------------------------------------------------------------------
 
  The Fund is a sub-trust of the Van Kampen Merritt Tax Free Fund, a
Massachusetts business trust organized August 15, 1985 (the "Trust"). Shares of
the Trust entitle their holders to one vote per share; however, separate votes
are taken by each sub-trust on matters affecting an individual sub-trust.
 
  The authorized capitalization of the Fund consists of an unlimited number of
shares of beneficial interest, without 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 "The
Distribution and Service Plans."
 
  Pursuant to an order of the SEC, 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 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 Class B Shareholders 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 a majority of the shares present and voting at
such meeting. The Trust will assist such holders in communicating with other
shareholders of the Fund to the extent required by
 
                                       46

the Investment Company Act. More detailed information concerning the Trust is
set forth in the Statement of Additional Information.
 
- --------------------------------------------------------------------------------
SHAREHOLDER REPORTS AND INQUIRIES

  The fiscal year of the Fund ends December 31. The Fund sends to its
shareholders, at least semi-annually, reports showing the Fund's portfolio and
other information. An annual report, containing financial statements audited by
Independent Auditors, 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.

                      STATEMENT OF ADDITIONAL INFORMATION
 
                VAN KAMPEN MERRITT NEW YORK TAX FREE INCOME FUND
 
   
  The 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 sub-trust
of Van Kampen Merritt Tax Free Fund, a Massachusetts business trust (the
"Trust").

of the Fund, and investors should obtain and read the Prospectus prior to

                             THE FUND AND THE TRUST
 
   
  The Fund is a separate sub-trust of the Trust, an open-end non-diversified
management investment company. At present, the Fund, Van Kampen Merritt Insured
Tax Free Income Fund, Van Kampen Merritt Tax Free High Income Fund, Van Kampen
Merritt Municipal Income Fund, Van Kampen Merritt Limited Term Municipal Income
Fund, Van Kampen Merritt California Insured Tax Free Fund, Van Kampen Merritt
New Jersey Tax Free Income Fund and Van Kampen Merritt Florida Insured Tax Free
Income Fund have been organized as sub-trusts of the Trust and have commenced
investment operations. Van Kampen Merritt California Tax Free Income Fund, Van
Kampen Merritt Michigan Tax Free Income Fund, Van Kampen Merritt Missouri Tax
Free Income Fund, and Van Kampen Merritt Ohio Tax Free Income Fund have been
organized as sub-trusts of the Trust and have not commenced investment
operations. Other sub-trusts may be organized and offered in the future.
    
 
  The Trust is an unincorporated business trust established under the laws of
the Commonwealth of Massachusetts by a Declaration of Trust dated August 15,
1985. The Declaration of Trust permits the Trustees to issue an unlimited number
of full and fractional shares in separate sub-trusts. Each share represents an
equal proportionate interest in the assets of the sub-trust with each other
share in such sub-trust and no interest in any other sub-trust. No sub-trust is
subject to the liabilities of any other sub-trust. The Declaration of Trust
provides that shareholders are not liable for any liabilities of the Trust or
any of its sub-trusts, requires inclusion of a clause to that effect in every
agreement entered into by the Trust or any of its sub-trusts 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 sub-trust on matters affecting an individual
sub-trust. For example, a change in investment policy for a sub-trust would be
voted upon by shareholders of only the sub-trust involved. 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 a majority of the shares present and voting at
such meeting.
 
  The Trustees may amend the Declaration of Trust (including with respect to any
sub-trust) in any manner without shareholder approval, except that the Trustees
may not adopt any amendment adversely affecting the rights of shareholders of
any sub-trust without approval by a majority of the shares of each affected
sub-trust present at a meeting of shareholders (or such higher vote as may be
required by the Investment Company Act of 1940, as amended (the "Investment
Company 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 bond
      market; however, the Fund will not invest more than 25% of its assets in
      industrial development bonds in a single industry.
 
   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
 
                                       B-2
<PAGE>   692
 
      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
      Securities and Exchange Commission (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.
 
   8. Invest in securities of other investment companies, except as part of a
      merger, consolidation or other acquisition and except that the Fund may
      invest up to 10% of its assets in tax-exempt investment companies that
      invest in securities rated comparably to those the Fund may invest in so
      long as the Fund does not own more than 3% of the outstanding voting stock
      of any tax-exempt investment company or securities of any tax-exempt
      investment company aggregating in value more than 5% of the total assets
      of the Fund.
 
   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 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 outstanding 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 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
 
                                       B-4
<PAGE>   694
 
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 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, 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 that are
 
                                       B-5
<PAGE>   695
 
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 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.
 
                                       B-6
<PAGE>   696
 
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 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
 
                                       B-7
<PAGE>   697
 
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.
 
  NEW YORK STATE. The State has historically been one of the wealthiest states
in the nation. For decades, however, the State has grown more slowly than the
nation as a whole, 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.
The City has also had to face 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 the City.
 
  The State has for many years had a very high state and local tax burden
relative to other states. The State and its localities have used these taxes to
develop and maintain their transportation networks, public schools and colleges,
public health systems, other social services and recreational facilities.
Despite these benefits 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.
 
  The 1993-94 State Financial Plan, adopted on April 16, 1993, is based on an
economic projection that the State will perform more poorly than the nation as a
whole. For calendar year 1993, the economy grew faster than in 1992, but still
at a very moderate rate, as compared to other recoveries. Moderate economic
growth is expected to continue in calendar year 1994 at a slightly faster rate
than in 1993. Economic recovery started considerably later in the State than in
the nation as a whole due in part to the significant retrenchment in the banking
and financial services industries, downsizing by several major corporations,
cutbacks in defense spending and an oversupply of office buildings. The forecast
made by the Division of the Budget for the overall rate of growth of the
national economy during calendar year 1994 is similar to the "consensus" of a
widely followed survey of national economic forecasters.
 
   
  The New York economy, as measured by employment, shifted from recession to
recovery near the start of calendar year 1993. During the course of calendar
year 1993, employment began to increase, albeit sporadically, and the
unemployment rate declined. However, the State economy turned in a mixed
performance during 1994. The moderate employment growth that characterized 1993
continued into mid-1994, then virtually ceased. Wages grew at around 3.5 percent
and personal income rose 4.0 percent in 1994. Employment growth is expected to
slow to less than 0.5 percent in 1995. Slow growth in employment and average
wages are expected to restrain wage growth to 3.2 percent. Many uncertainties
exist in forecasts of both the national and State economies, including
employment levels and consumer attitudes toward spending, Federal fiscal and
monetary policies and the condition of the world economy, which could have an
adverse effect on the State. There can be no assurance that the State economy
will not experience worse-than-predicted results in the 1994-95 and 1995-96
fiscal years, with corresponding material and adverse effects on the State's
projections of receipts and disbursements.

  The General Fund is the largest and most significant of the dozens of funds
maintained by the State. The 1991-92 fiscal year was the fourth consecutive year
in which the State incurred a cash-basis operating deficit in the General Fund
and issued deficit notes. During the 1991-92 fiscal year, estimates and
projections of the State's operating results were revised on several occasions
to reflect changing economic and financial conditions, and those revisions were
reflected in quarterly updates to the State's Financial Plan for the 1991-92
fiscal year initially formulated on June 10, 1991. For the 1991-92 fiscal year,
the State incurred a cash-basis operating deficit in the General Fund of $575
million, which, after a $44 million withdrawal from the Tax Stabilization
Reserve Fund, was financed through the public issuance of $531 million of tax
and revenue anticipation notes on March 30, 1992 (the "1992 Deficit Notes").
 
  General Fund receipts, excluding transfers from other funds, totalled $28.818
billion in the State's 1991-92 fiscal year (before repayment of $1.081 billion
of deficit notes issued in its 1990-91 fiscal year and before issuance of $531
million in deficit notes to close the 1991-92 fiscal year General Fund cash
basis operating deficit), $29.950 billion in the State's 1992-93 fiscal year
(before repayment of $531 million in deficit notes issued to close the State's
1991-92 fiscal year General Fund cash basis deficit, and $30.579 billion in the
State's 1993-94 fiscal year). General Fund receipts in the State's 1994-95
fiscal year are estimated in the 1994-95 State Financial Plan at $34.321
billion. Taxes account for 96% of estimated 1994-95 General Fund receipts, with
the balance comprised of miscellaneous receipts. Major components of the tax
receipts in the General Fund and the approximate percentages of actual fiscal
year 1993-94 General Fund receipts and estimated fiscal year 1994-95 General
Fund receipts for which they account, include the personal income tax (50% and
54%, respectively), user taxes and fees (including the State Sales and Use Tax)
(19% and 20%, respectively), business taxes (18% and 16%, respectively), other
taxes (3% and 3%, respectively) and miscellaneous receipts (3.9% and 3.7%,
respectively).
 
   
  General Fund disbursements, exclusive of transfers to other funds, totalled
$28.058 billion in the State's 1991-92 fiscal year, $29.068 billion in the
State's 1992-93 fiscal year, and $30.152 billion in the State's 1993-94 fiscal
year and are estimated to total $34.248 billion in the State's 1994-95 fiscal
year. Major General Fund disbursements categories and the approximate
percentages of estimated fiscal year 1994-95 General Fund disbursements for
which they account, include grants to local governments (including aid to
education, social services and State revenue sharing) (70%), State operations
spending (18%) (approximately 71% of projected disbursements in this category
are for personal service costs), general State charges (6%) (including
contributions to pension systems and employee fringe benefits), capital
expenditures (2%) and disbursement for interest payments on the State's
short-term tax and revenue anticipation note and bond anticipation note (4%).
    
 
   
  For its 1992-93 fiscal year the State had a balanced budget on a cash basis
with a positive margin of $671 million in the General Fund that was deposited in
the refund reserve account. During its 1991-92 and 1990-91 fiscal years, the
State incurred cash basis operating deficits, prior to the issuance of TRANs,
owing to lower-than-projected receipts, which it believes to have been
principally the result of a significant slowdown in the New York and regional
economy.
    
 
  After reflecting a 1992-93 year-end deposit to the refund reserve account of
$671 million, reported 1992-93 General Fund receipts were $45 million higher
than originally projected in April 1992. If not for that year-end transaction,
which had the effect of reducing 1992-93 receipts by $671 million and making
those receipts available in 1993-94, General Fund receipts would have been $716
million higher than originally projected.
 
  The favorable performance was primarily attributable to personal income tax
collections that were more than $700 million higher than originally projected
(before reflecting the refund reserve transaction). The withholding and
estimated payment components of the personal income tax exceeded original
estimates by more than $800 million combined, reflecting both stronger economic
activity, particularly at year's end, and the tax-induced one-time acceleration
of income into 1992. Modest short-falls were experienced in other components of
the income tax.
 
  There were large, but largely offsetting, variances in other categories.
Significantly higher-than-projected business tax collections and the receipt of
unbudgeted payments from the Medical Malpractice Insurance Association and the
New York Racing Association approximately offset the loss of an anticipated $200
million
 
                                       B-9
<PAGE>   699
 
Federal reimbursement, the loss of certain budgeted hospital differential
revenue as a result of unfavorable court decisions, and shortfalls in certain
miscellaneous revenue sources.
 
  Disbursements and transfers to other funds totaled $30.829 billion, an
increase of $45 million above projections in April 1992. After adjusting for the
impact of a $150 million payment from the Medical Malpractice Insurance
Association to health insurers made pursuant to legislation passed in January
1993, actual disbursements were $105 million lower than projected. This
reduction primarily reflected lower costs in virtually all categories of
spending, including Medicaid, local health programs, agency operations, fringe
benefits, capital projects and debt service as partially offset by
higher-than-anticipated costs for educational programs.
 
  The use of New York Local Government Assistance Corporation bond proceeds to
make payments to local governmental units, otherwise made by the State, reduces
the State's future liabilities. Therefore, the projected 1994-95 General Fund
GAAP-basis operating deficit reflected above includes $315 million to reflect
payment by LGAC to local governmental units.
 
   
  As of March 31, 1994, the State had approximately $5.146 billion in general
obligation bonds, excluding Refunding Bonds, and $224 million in BANs
outstanding. On May 4, 1993 the State issued $850 million in TRANs, all of which
matured on December 31, 1993. Principal and interest due on general obligation
bonds and interest due on BANs and on TRANs were $782.5 million for the State's
1993-94 fiscal year, and are estimated to be $786.3 million for the State's
1994-95 fiscal year, not including interest on the Refunding Bonds to the extent
that such interest is to be paid from escrowed funds.
    
 
   
  The State issued $850 million in TRANs on May 4, 1993 to fund its day-to-day
operations and certain local assistance payments to its municipalities and
school districts. These TRANs were fully retired on December 31, 1993. The State
met its cash flow needs in its 1994-95 fiscal year without the issuance of
TRANs.
    
 
   
  The State completed its 1993-94 fiscal year with a combined Governmental Funds
operating surplus of $1.051 billion, which included an operating surplus of
$1.051 billion, which included on operating surplus in the General Fund of $914
million, in the Special Revenue Funds of $149 million and in the Debt Service
Funds of $23 million, and an operating deficit in the Capital Projects Funds of
$35 million. The General Fund is projected to be balanced on a cash basis for
the 1994-95 fiscal year. Total receipts are projected to be $34.321 billion, an
increase of $2.092 billion over total receipts in the prior fiscal year. Total
General Fund disbursements are projected to be $34.248 billion, an increase of
$2.351 billion over the total amount disbursed and transferred in the prior
fiscal year.
    
 
   
  The Financial Plan for the 1995-96 fiscal year released on February 1, 1995,
projects General Fund receipts, including transfers from other funds, of $32.516
billion, a reduction of $747 million from the revised 1995-95 State Financial
Plan. Tax receipts are projected at $29.391 billion for the 1995-96 fiscal year,
a reduction of $1.071 billion from the prior year. Although growth in the base
of tax receipts is expected to accelerate during the 1995-96 fiscal year, tax
receipts are expected to fall by 3.5 percent, principally due to the combined
effect of implementing during the 1995-96 fiscal year (1) a portion of tax
reductions enacted in 1987 and deferred since 1990, (2) additional tax cuts to
prevent tax increases enacted in 1987 from taking effect and (3) a proposed
employer day care credit, together with the incremental cost of tax reductions
enacted in 1994.
    
 
   
  Disbursements in the General Fund are projected to total $32.361 billion in
1995-96, a decrease of $1,144 million or 3.4 percent. Grants to local government
are preserved at 1994-95 levels generally, although costs for social welfare
programs are recommended to be dramatically reduced. Spending for State
operations is projected to decline by $485 million, or 7.7 percent, to the
lowest level since the 1985-86 fiscal year.
    
 
  There can be no assurance that the State 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 State programs at current levels. To address any potential
budgetary imbalance, the State may need to take significant actions to align
recurring receipts and disbursements in future fiscal years.
 
  Projections and estimates of receipts from taxes have been subject to
significant variance in recent fiscal years. The personal income tax, the sales
tax and the corporation franchise tax have been particularly subject to
overestimation as a result of several factors, most recently a significant
slowdown in the national and
 
                                      B-10
<PAGE>   700
 
regional economies and uncertainties in taxpayer behavior as a result of actual
and proposed changes in Federal tax laws.
 
   
  In June 1990, as part of a state fiscal reform program, legislation was
enacted creating the New York Local Government Assistance Corporation ( "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. Over a period of years, the issuance of those
long-term obligations, which will be amortized over no more than 30 years, is
expected to result in eliminating the need for continuing short-term seasonal
borrowing for those purposes. 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. As of December 1, 1994, LGAC had issued its bonds to provide net
proceeds of $3.856 billion and has been authorized to issue its bonds to provide
net proceeds of up to an additional $315 million during the State's 1994-95
fiscal year.
    
 
  In April 1993, legislation was also enacted providing for significant changes
in the long-term financing practices of the State and the Authorities.
 
  The Legislature passed a proposed constitutional amendment that would permit
the State, without a voter referendum but within a formula-based cap, to issue
revenue bonds, which would be debt of the State secured solely by a pledge of
certain State tax receipts (including those allocated to State funds dedicated
for transportation purposes), and not by the full faith and credit of the State.
In addition, the proposed amendment would require that State debt be incurred
only for capital projects included in a multi-year capital financing plan and
would prohibit lease-purchase and contractual-obligation financing mechanisms
for State facilities. Public hearings have been held on the proposed
constitutional amendment. Following these hearings, in February 1994, the
Governor and the State Comptroller recommended a revised constitutional
amendment which would further tighten the ban on lease-purchase and
contractual-obligation financing, incorporate existing lease-purchase and
contractual-obligation debt under the proposed revenue bond cap while
simultaneously reducing the size of the cap. After considering these
recommendations, the Legislature passed a revised constitutional amendment which
tightens the ban, and provides for a phase-in to a lower cap (4.4 percent of
personal income).
 
  Before the approved constitutional amendment or any revised amendment enacted
in 1994 can be presented to the voters for their consideration, it must be
passed by a separately elected legislature. The amendment must therefore be
passed by the newly elected Legislature in 1995 prior to presentation to the
voters at the earliest in November 1995. The amendment could not become
effective before January 1, 1996.
 
  State legislation has also been enacted to provide for the deposit of
petroleum business tax receipts and certain other transportation-related taxes
and fees into certain funds dedicated to transportation purposes. For the
purpose of financing various State and local highway and bridge projects prior
to the submission of the proposed constitutional amendment to the voters for
their consideration, the New York State Thruway Authority was authorized to
issue up to approximately $4 billion of bonds, the debt service on which,
subject to annual appropriation, is expected to be paid from a portion of the
dedicated funds. In addition, the legislation provides for the payment of a
portion of the dedicated transportation funds to the Metropolitan Transportation
Authority expected to be used in connection with its 1992-96 Capital Program.
 
  Ratings. On January 13, 1992, S&P lowered its rating on the State's general
obligation bonds to A- from A stating that it continues to assess the State's
rating outlook as "negative" and that "[n]ear term prospects for significant
economic recovery appear dismal." 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. Various agency
debt, State moral obligations, contractual obligations, lease purchase
obligations and state guarantees are also affected by the S&P action. S&P also
continued its negative rating outlook assessment on State general obligation
debt. On April 26, 1993, S&P revised the rating outlook assessment to stable. On
February 14, 1994, S&P raised its outlook to positive and, on December 12, 1994,
confirmed its A- rating. S&P's previous
 
                                      B-11
<PAGE>   701
 
ratings were A from March 1990 to January 1992, AA- from August 1987 to March
1990 and A+ from November 1982 to August 1987. 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. There is no assurance that a
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.
 
  Authorities. Certain authorities and public benefit corporations of the State,
including the State Housing Finance Authority ("HFA"), the Battery Park City
Authority ("BPCA"), the Metropolitan Transportation Authority ("MTA") and the
Urban Development Corporation ("UDC"), have faced and continue to experience
substantial financial difficulties which could adversely affect the ability of
such authorities to make payments of interest on, and principal amounts of,
their respective bonds. The difficulties have in certain instances caused the
State (under so-called "moral obligation") to appropriate funds on behalf of the
authorities. Moreover, it is expected that the problems faced by these
authorities will continue and will require increasing amounts of State
assistance in future years. Failure of the State to appropriate necessary
amounts or to take other action to permit those authorities having financial
difficulties to meet their obligations (including HFA, UDC, MTA and BPCA) could
result in a default by one or more of the authorities. Such default, if it were
to occur, would be likely to have a significant adverse effect on investor
confidence in, and therefore the market price of, obligations of the defaulting
authority and of State, City and Municipal Assistance Corporation ("MAC")
obligations. In addition, any default in payment on any general obligation of
any authority whose bonds contain a moral obligation provision could constitute
a failure of certain conditions that must be satisfied in connection with
Federal guarantees of City and MAC obligations and could thus jeopardize the
City's long-term financing plans.
 
  As of September 30, 1993, the latest data available, there were eighteen
authorities that each had outstanding debt of $100 million or more. These
eighteen authorities had an aggregate of $63.5 billion of outstanding debt on
such date, of which approximately $7.3 billion was moral obligation debt and
approximately $21.0 billion was financed under lease-purchase or contractual
obligation financing arrangements.
 
  The State Constitution provides that the State may guarantee the repayment of
certain borrowings to carry out designated projects by the New York State
Thruway Authority, the Job Development Authority and the Port Authority of New
York and New Jersey. As of March 31, 1994, a total of $412 million in such
State-guaranteed debt was outstanding. The State has never been called upon to
make any direct payments pursuant to such guarantees. The constitutional
provisions allowing a State-guarantee of certain Port Authority of New York and
New Jersey debt stipulates that no such guaranteed debt may be outstanding after
December 31, 1996. In addition, the State-guaranteed bonds issued by the Thruway
Authority are scheduled to be fully retired by July 1, 1995.
 
  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.

  On November 16, 1993, the Court of Appeals, the State's highest court,
affirmed the decision of the Appellate Division (Third Department) of the
State's Supreme Court in three actions (McDermott, et al. v. Regan, et al.;
Puma, et al. v. Regan, et al.; and Guzdek, et al. v. Regan, et al.) declaring
unconstitutional certain legislation enacted in 1990. That legislation mandated
a change in the actuarial funding method for determining contributions by the
State and its local governments to the State and local retirement systems from
the aggregate cost ("AC") method, previously used by the Comptroller, to the
projected unit credit ("PUC") method, and it required the application of the
surplus reported under the PUC method as a credit to employer contributions. As
a result, contributions to the retirement systems have been significantly
reduced since the State's 1990-91 fiscal year. The Court of Appeals held, among
other things, that the State Constitution, which prohibits the benefits of
membership in the retirements systems from being impaired or diminished, was
violated because the PUC legislation impaired the means designed to assure
benefits to public employees by depriving the Comptroller of his personal
responsibility to maintain 'the security and sources of benefits' of the pension
fund. As a result of this decision, the Comptroller has developed a plan to
return to the AC method and to restore prior funding levels of the retirement
systems. The Comptroller expects to achieve this objective in a manner that,
consistent with his fiduciary responsibilities, will neither require the State
to make additional contributions in its 1993-94 fiscal year nor materially and
adversely affect the financial condition of the State thereafter. The
Comptroller's plan calls for a return to the AC method, using a four-year
phase-in in the New York State and Local Employees' Retirement System ("ERS"),
with State AC contributions to ERS capped at a percentage of payroll that
increases each year during the phase-in. Although State contributions to ERS
under the plan are expected to be lower during the phase-in period than they
would have been if the AC method were reinstated immediately, they are expected
to exceed PUC levels by $30 million in fiscal 1994-95, $63 million in fiscal
1995-96, $116 million in fiscal 1996-97, and $193 million in fiscal 1997-98. The
excess over PUC levels is expected to peak at $241 million in fiscal 1998-99,
when State contributions under the Comptroller's plan are first projected to
exceed levels that would have been required by an immediate return to the AC
method. The excess over PUC levels is projected to decline after fiscal 1998-99,
and, beginning in fiscal 2001-02, State contributions required under the
Comptroller's plan are projected to be less than PUC requirements would have
been.
 
  On May 31, 1988 the Supreme Court of the United States took jurisdiction of a
claim of the State of Delaware that certain unclaimed dividends, interest and
other distributions made by issuers of securities and held by New York-based
brokers incorporated in Delaware, for beneficial owners who cannot be identified
or located, had been, and were being, wrongfully taken by the State of New York
pursuant to New York's Abandoned Property Law (State of Delaware v. State of New
York, United States Supreme Court). Texas intervened, claiming a portion of such
distributions and similar property taken by the State of New York from New
York-based banks and depositories incorporated in Delaware. All other states and
the District of Columbia moved to intervene. In a decision dated March 30, 1993,
the United States Supreme Court granted all pending motions of the states and
the District of Columbia to intervene and remanded the case to a Special Master
for further proceedings consistent with the Court's decision. The Court
determined that the abandoned property should be remitted first to the state of
the beneficial owner's last known address, if ascertainable, and, if not, then
to the state of incorporation of the intermediary bank, broker or depository. On
January 21, 1994, the State entered into a settlement agreement with Delaware.
The State made an immediate $35 million payment to Delaware in the 1993-94
fiscal year and agreed to make annual payments of $33 million in each of the
next five fiscal years. The claims of the other states and the District of
Columbia remain. The State anticipates that, as a final resolution of this
proceeding, additional payments, in an amount which may be significant, may be
required during the State's 1993-94 fiscal year or thereafter.
 
  The State is also engaged in a variety of constitutional claims wherein
significant monetary damages are sought. The State is a party to actions
commenced by several Indian nations which claim that significant amounts of land
were unconstitutionally taken from those tribes in violation of various treaties
and agreements during the eighteenth and nineteenth centuries. The claimants
seek recovery of approximately six million acres of land as well as compensatory
and punitive damages. The amounts of potential losses, if any, are not presently
determinable. Also, the State is a party to several actions challenging the
constitutionality of specified bonding and other financing programs.
 
                                      B-13
<PAGE>   703
 
  Adverse developments in the foregoing proceedings or new proceedings could
adversely affect the financial condition of the State in its current fiscal year
or thereafter. With respect to pending and threatened litigation, the State has
reported liabilities of $675 million for awarded and anticipated unfavorable
judgments in its audited financial statements for the 1993-94 fiscal year.
 
  Other Localities. In 1992, the total indebtedness of all localities in the
State was approximately $35.2 billion, of which $19.5 billion was debt of the
City (excluding $5.9 billion in MAC debt); a small portion (approximately $71.6
million) of the $35.2 billion of indebtedness represented borrowing to finance
budgetary deficits and was issued pursuant to enabling State legislation. In
1992, an unusually large number of local government units requested
authorization for deficit financings. According to the Comptroller, ten local
government units were authorized to issue deficit financing in the aggregate
amount of $131.1 million, including Nassau County for $65 million in six-year
deficit bonds and Suffolk County for $36 million in six-year deficit bonds. The
current session of the Legislature may receive as many or more requests for
deficit-financing authorizations as a result of deficits previously incurred by
local governments. Although the Comptroller has indicated that the level of
deficit financing requests in 1992 was unprecedented, in 1993, five localities
were authorized to issue only $5.5 million in deficit financing indebtedness.
Such deficit financing by localities is not expected to have a material adverse
effect on the financial condition of the State.
 
  Fiscal difficulties experienced by the City of Yonkers resulted in the
creation 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 Governor or the State
Legislature to assist Yonkers could result in allocation of State resources in
amounts that cannot yet be determined.
 
  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
accounts for approximately 41% of the State's population and personal income.
 
  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 MAC to assist with long-term financing for the City's short-term debt
and other cash requirements and (ii) created the 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")).
 
  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 the 1978 fiscal year the City's annual financial
statements, prepared in accordance with generally accepted accounting principles
("GAAP"), have been audited by independent certified accountants and four-year
financial plans have been prepared annually for the City and the Covered
Organizations.
 
  The Mayor is responsible for preparing the City's four-year financial plan,
including the City's current financial plan for the 1994 through 1997 fiscal
years (the "1994-97 Financial Plan" or "Financial Plan"). 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. The City
Comptroller and other agencies and public officials have issued reports which,
among other things, state that projected revenues may be less and future
expenditures may be greater than those forecast in the City's Financial Plan. 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 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
 
                                      B-14
<PAGE>   704
 
the City's ability to balance its budget as required by State law and to meet
its annual cash flow and financing requirements. Such assumptions and
contingencies include the timing of any regional and local economic recovery,
the absence of wage increases in excess of the increases assumed in the 1994-97
Financial Plan, employment growth, provision of State and Federal aid and
mandate relief, State legislative approval of future State budgets, adoption of
City budgets by the New York City Council, and approval by the Governor or the
State Legislature of various other actions proposed in the 1994-97 Financial
Plan.
 
  The 1993-94 State budget, as enacted, included $400 million less in State
actions than the City had anticipated. As a result of adjustments to education
aid formulas, the City received an additional $145 million in education funds.
However, the State Legislature failed to enact a takeover of local Medicaid
costs, other significant mandate relief items and certain Medicaid cost
containment items proposed by the Governor, which would have provided the City
with savings. The adopted State budget increased sanctions on social service
programs, eliminated the pass-through of a State surcharge on parking tickets,
cut reimbursement for transportation operations under the Consolidated Local
Highway Assistance Program, and required a large contribution in City funds to
hold the Metropolitan Transit Authority ("MTA") fare at the current level. In
the event of any significant reduction in projected State revenues or increases
in projected State expenditures from the amounts currently projected by the
State, there could be an adverse impact on the timing and amounts of State aid
payments to the City in the future.
 
  Implementation of the 1995-98 Financial Plan is also dependent upon the City's
ability to market its securities successfully in the public credit markets. The
City's financing program for fiscal years 1995 through 1998 contemplates the
issuance of $1.7 billion of general obligation bonds primarily to reconstruct
and rehabilitate the City's infrastructure and physical assets and to make
capital investments. 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 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, it would be prevented from meeting its planned operating and capital
expenditures.
 
  The City Comptroller and other agencies and public officials have issued
reports and made public statements which, among other things, state that
projected revenues may be less and future expenditures may be greater than those
forecast in the 1995-98 Financial Plan. In addition, the Control Board staff and
other agencies have questioned whether the City has the capacity to generate
sufficient revenues in the future 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.
 
  For each of the past twelve fiscal years, the City achieved balanced operating
results as reported in accordance with GAAP and the City's 1994 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 reductions in City services, which
could adversely affect the City's economic base.
 
ACTIONS TO CLOSE THE GAPS
 
   
  The 1995-1998 Financial Plan reflects a program of proposed actions by the
City, State and Federal governments to close the gaps between projected revenues
and expenditures of $2.7 billion, $3.2 billion and $3.8 billion for the 1996,
1997 and 1998 fiscal years, respectively.
    
 
   
  City gap-closing actions, a substantial number of which are unspecified,
include additional spending reductions, the reduction of City personnel through
attrition, government efficiency initiatives, procurement initiatives and labor
productivity initiatives. Certain of these initiatives may be subject to
negotiation with the City's municipal unions.
    
 
   
  State actions proposed in the gap-closing program total $1.3 billion in the
1996 fiscal year. These actions include savings primarily from the proposed
State assumption of certain Medicaid costs.
    
 
   
  The Federal actions proposed in the gap-closing program total $145 million in
increased Federal assistance in fiscal year 1996.

  Various actions proposed in the Financial Plan, including the proposed
increase in State aid, are subject to approval by the Governor and the State
Legislature, and the proposed increase in Federal aid is subject to approval by
Congress and the President. State and Federal actions are uncertain and no
assurance can be given that such actions will in fact be taken or that the
savings that the City projects will result from these actions will be realized.
The State Legislature failed to approve a substantial portion of the proposed
State assumption of Medicaid costs in the last session. The Financial Plan
assumes that these proposals will be approved by the State Legislature during
the 1996 fiscal year and that the Federal government will increase its share of
funding for the Medicaid program. If these measures cannot be implemented, the
City will be required to take other actions to decrease expenditures or increase
revenues to maintain a balanced financial plan.
 
  The City's projected budget gaps for the 1997 and 1998 fiscal years do not
reflect the savings expected to result from prior years' programs to close the
gaps set forth in the Financial Plan. Thus, for example, recurring savings
anticipated from the actions which the City proposes to take to balance the
fiscal year 1996 budget are not taken into account in projecting the budget gaps
for the 1997 and 1998 fiscal years.
 
  Although the City has maintained balanced budgets in each of its last fourteen
fiscal years, and is projected to achieve balanced operating results for the
1995 fiscal year, there can be no assurance that the gap-closing actions
proposed in the Financial Plan can be successfully implemented or that the City
will maintain a balanced budget in future years without additional State aid,
revenue increases or expenditure reductions. Additional tax increases and
reductions in essential City services could adversely affect the City's economic
base.
 
  From time to time, the Control Board staff, MAC, 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 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 March 7, 1995, the City Comptroller issued a report which concluded that
the budget gap for the 1996 fiscal year, before implementation of the
gap-closing actions proposed in the Financial Plan, may be between $338 million
and $538 million greater than set forth in the Financial Plan. The increase in
the budget gap identified in the report is primarily due to (i) a $39 million
shortfall in tax revenues beyond that projected in the Financial Plan; (ii)
increased overtime costs of $128 million; (iii) health insurance expenditures
which may exceed those projected in the Financial Plan by $149 million, due to
uncertainties as to projected savings to be negotiated with municipal unions;
and (iv) pension costs which could be $200 million greater than assumed in the
Financial Plan as a result of the implementation of the recommendations of a
recently completed actuarial audit of the City's pension systems.
    
 
   
  With respect to the 1996 fiscal year, the City Comptroller identified
uncertainties of between $1.5 billion and $2.1 billion in the gap-closing
program in the 1996 fiscal year. The risks for the 1996 fiscal year included
uncertainties concerning increased Federal aid and proposed reduction in City
expenditures for health care costs, approval by the State Legislature of certain
measures and $600 million in labor initiatives to be negotiated with the City's
labor unions, in addition to a number of the uncertain proposals identified as
substantial risks for the 1995 fiscal year.
    
 
   
  In February 1995, the City Comptroller issued a report on the City's Financial
Plan. The City Comptroller stated that there were substantial risks for the 1995
fiscal year totaling $218 million, including risks with respect to a possible
$67 million in overtime costs in excess of budget; possible increased public
assistance costs of $10 billion; possible additional payments of the City's
share of HHC Medicaid totaling $51 million; and possible additional payments by
the City to the Board of Education, totalling $90 million.
    
 
                                      B-16
<PAGE>   706
 
   
  In early December, 1994, the City Comptroller issued a subsequent report which
concluded that the risks for the 1995 fiscal year had increased from $408
million to $453 million, as a result of the termination of negotiations between
the City and the Port Authority regarding renegotiation of the terms of certain
Port Authority leases. In addition, the City Comptroller noted that the City is
currently seeking to develop and implement plans which will satisfy the Federal
Environmental Protection Agency that the water supplied by the City watershed
areas does not need to be filtered. The City Comptroller noted that, if the City
is ordered to build filtration plants, they could cost as much as $4.57 billion
to construct, with annual debt service and operating costs of more than $500
million, leading to a water rate increase of 45%.
    
 
  On January 17, 1995, the City Comptroller issued a report which concluded that
the risks for the 1995 fiscal year had increased from $453 million to $658
million, primarily as a result of lower than projected tax revenues totaling
$400 million, partially offset by the anticipated receipt of an additional $100
million of revenues from the refund by the Internal Revenue Service of social
security overpayments by the City in the 1995 fiscal year. The report stated
that the shortfall in tax revenue collections is explained largely by weaknesses
in the banking industry and the securities sector, which have been hurt by the
tight monetary policies of the Federal Reserve Board which have resulted in
losses from bond trading operations, layoffs and lower year-end bonuses. The
report stated that this shortfall may increase if total returns in the financial
sector do not improve in the first half of the 1995 calendar year.
 
  On December 16, 1994, the City Comptroller issued a report noting that the
capacity of the City to issue general obligation debt could be greatly reduced
in future years due to the decline in value of taxable real property. The report
noted that, under the State constitution, the City is permitted to issue debt in
an amount not greater than 10% of the average full value of taxable real estate
for the current year and previous year, that the latest estimates produced by
the State Board of Equalization and Assessment relating to the full value of
real property, using data from a 1992 survey, indicate a 19% decline in the
market value of taxable real property from the previous survey in 1990, and that
the State Board has decided to use a projected annual growth rate of 8.84%, as
compared to its previous projection of 14% for estimating full value after 1992.
The report concludes that the City will be within the projected legal debt
incurring limit in the 1996 fiscal year. However, the report concluded that
based on the most likely forecast of full value of real property, the debt
incurring power of the City would be curtailed in the 1997 and 1998 fiscal years
substantially. The City Comptroller recommended, among other things
prioritization of capital projects to determine which can be delayed or
cancelled, and better maintenance of the City's physical plant and
infrastructure, which would result in less capital spending for repair and
replacement of capital structures.
 
  On December 27, 1994, the City Comptroller issued a report on the City's
economy which noted that the City's economic recovery had slowed in the third
quarter of the 1994 calendar year and concluded that the City's economy is still
very weak and the local recovery is very fragile. The report noted that the
indications of weakness in the City's economy include slower growth in payroll
employment and retail sales in the third quarter, as well as softness in the
Manhattan commercial real estate market. The report also noted that the tight
monetary policies implemented by the Federal Reserve Bank since February to curb
inflationary pressures were particularly harmful to interest rate sensitive and
cyclical sectors, such as retailing, the securities industry, banking and
manufacturing and that the City's service-driven economy has not benefited from
the national recovery, which was largely driven by interest rate sensitive
sectors of housing, capital goods and consumer durable goods. The report noted
that the slow-down in economic activity is expected to continue in the fourth
quarter of 1994, with more cutbacks in local governments and additional layoffs
in the financial sector, which will offset new hiring in other areas and result
in a slow growth in the 1995 calendar year.
 
   
  On February 28, 1995, OSDC issued a report reviewing the Financial Plan
relating to the 1995 fiscal year, with additional comments on the 1996 fiscal
year. The report concluded that a budget gap of $41 million exists for the 1995
fiscal year, due primarily to a possible increase in City-funded Medicaid
payments to HHC and noted that the $150 million general reserve shown in the
Financial Plan is more than adequate to offset this problem. The report also
identified potential risks for the 1995 fiscal year totaling, net of offsets,
$297 million, including overspending at BOE; uncertainty concerning projected
additional State assistance to BOE and HHC; and the purchase by the State of two
City jails, which requires the approval of the State Legislature. In addition,
the report pointed out the uncertain impact on the City and HHC of the State
budget for the State's 1996 fiscal year to be adopted in April 1995, and
expressed concern about the City's increasing reliance on
    
 
                                      B-17
<PAGE>   707
 
   
one-time resources to support recurring expenses. With respect to the 1996
fiscal year, the report noted that the City-projected $2.7 billion budget gap
for the 1996 fiscal year representing 13% of City-fund revenues is the largest
budget gap, both in absolute terms and on a percentage basis, which has been
projected for the next succeeding fiscal year at this stage of the budget
planning process for the last 15 years. The OSDC report noted that the most of
the resources anticipated in the gap-closing program require the cooperation of
the Federal or State governments, or municipal unions, and that it is likely
that a number of the initiatives, including those that seek to reduce
expenditures for entitlement programs, could be the subject of litigation which
might delay any proposed savings for the City. For these reasons, the report
urged the City to prepare and make public detailed contingency plans that are
within its control to implement. The report also expressed concern about the
impact of the gap-closing program on education and health care services and the
City's economy.
    
 
   
  On December 8, 1994, the staff of the Control Board issued a report on the
Financial Plan. In its report the staff concluded that the City faced risks of
more than $513 million in the 1995 fiscal year. The staff noted that tax
receipts are stagnant, primarily because of a further contraction in the
property tax and sluggish growth in the non-property taxes, related to erosion
of profits in the securities industry, and that there are substantial risks for
the 1995 fiscal year with respect to possible increased overtime and City
Medicaid payments to HHC, shortfalls in parking fine collections, the projected
refund of social security payments, a proposed asset sale, the renegotiation of
certain Port Authority leases and possible additional expenditures at BOE. In
addition, the staff indicated that there are risks of $2.0 billion, $2.6 billion
and $3.1 billion for the 1996, 1997 and 1998 fiscal years, respectively. Risks
for the 1996 through 1998 fiscal years include the potential for increased
overtime and lower non-property tax revenues, increased spending for City
Medicaid payments to HHC, additional expenditures at BOE, uncertainties
concerning the proposed reduction in City expenditures for health care costs,
the anticipated revenues from renegotiation of the terms of certain Port
Authority leases, savings resulting from the proposed tort reform program to
limit damage claims against the City, and increased Federal aid for Medicaid.
The report noted that the City faced additional risks with respect to its
assumptions regarding pension costs, a reduced subsidy to the Transit Authority,
social services savings and the cost of wages. The staff noted that it is
imperative that the City Council and the Mayor work together to ensure that the
actions taken for the 1995 fiscal year are recurring and help reduce the $2
billion gap for the 1996 fiscal year, and that a cooperative effort is necessary
if the City is to solve its structural budget problems and bring stability to
the delivery of services to its residents.
    
 
  On March 23, 1994, the staff of the Control Board issued its report on the
current Financial Plan. The report states that, while the Financial Plan moves
the City in the direction of structural balance, it has more risks and fewer
details than are desirable. With respect to the 1994 fiscal year, the report
concludes that the budget is reliably balanced. However, for the 1995 fiscal
year, the report notes that decisions will have to be made in the next
modification to the Financial Plan in April 1994 whether to include in the
Financial Plan for the 1995 fiscal year certain proposed additional revenues and
savings, which are outside the Mayor's direct control and which require the
support of third parties.
 
  Although the City has maintained balanced budgets in each of its last thirteen
fiscal years, and is projected to achieve balanced operating results for the
1994 fiscal year, there can be no assurance that the gap-closing actions
proposed in the 1994-97 Financial Plan can be successfully implemented or that
the City will maintain a balanced budget in future years without additional
State aid, revenue increases or expenditure reductions. Additional tax increases
and reductions in essential City services could adversely affect the City's
economic base.
 
  Collective Bargaining Agreements. Nearly all of the City's collective
bargaining agreements with the large municipal unions representing civilian and
uniformed employees expired some time during the 1992 fiscal year. On January
11, 1993, the City announced a settlement with a coalition of municipal unions,
including Local 237 of the International Brotherhood of Teamsters ("Local 237"),
District Council 37 of the American Federation of State, County and Municipal
Employees ("District Council 37") and other unions covering approximately 44% of
the City's workforce. The settlement, which has been ratified by the unions,
includes a total net expenditure increase of 8.25% over a 39-month period,
ending March 31, 1995 for most of these employees. On April 9, 1993 the City
announced an agreement with the Uniformed Fire Officers Association (the "UFOA")
which is consistent with the coalition agreement and which has been ratified. On
August 30,
 
                                      B-18
<PAGE>   708
 
1993, the BOE and the City announced an agreement with the United Federation of
Teachers ("UFT"). The agreement, which has been ratified by the UFT members, is
generally consistent with the coalition agreement. However, while the coalition
agreement covers a period of 39 months, the UFT agreement is for 48 1/2 months.
The Financial Plan reflects the costs for all City-funded employees associated
with these settlements and provides for similar increases for all other
City-funded employees. Additional expenditures aggregating $42 million for
fiscal year 1995 and $79 million for each year thereafter have been added to the
Financial Plan to provide funding for the additional 9 1/2 months provided for
under the UFT agreement. Subsequently, the City has reached agreement with all
except four of its major bargaining units under terms which are generally
consistent with the coalition agreement. The City is presently bargaining with
the Correction Officers' Benevolent Association ("COBA") and the Sanitation
Officers' Association ("SOA"). In addition, the Transit Police Benevolent
Association's ("TPBA") delegate body rejected a tentative settlement with the
City. The contract dispute is currently being arbitrated before the State's
Public Employment Relations Board. Moreover, a contract dispute between the City
and the Licensed Practical Nurses ("LPN's") is currently in arbitration before
the City's Office of Collective Bargaining ("OCB").
 
  The Financial Plan provides no additional wage increases for City employees
after their contracts expire in the 1995 and 1996 fiscal years. Each 1% wage
increase for all employees commencing in the 1995 and 1996 fiscal years would
cost the City an additional $28 million for the 1995 fiscal year, $140 million
for the 1996 fiscal year and $150 million each year thereafter above the amounts
provided for in the Financial Plan.
 
  In the event of a collective bargaining impasse, the terms of wage settlements
could be determined through the impasse procedure in the New York City
Collective Bargaining Law, which can impose a binding settlement.
 
  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 1994-97 Financial Plan. As of June 30, 1994, the
City estimated its potential future liability on account of all outstanding
claims to be approximately $2.6 billion.
 
  Outstanding Indebtedness. As of September 30, 1994, the City had $21.218
billion of outstanding net long-term indebtedness. As of September 30, 1994, MAC
had $4.146 billion of outstanding net long-term indebtedness.
 
   
  Ratings. As of June 28, 1993, Moody's rated the City's general obligation
bonds Baa1 and S&P rated such bonds A-. On January 17, 1995, S&P placed the
City's General Obligation Bonds on CreditWatch with negative implications. Such
ratings reflect only the views of Moody's and S&P, from which an explanation of
the significance of such ratings may be obtained. There is no assurance that
such ratings will continue for any given period of time or that they will not be
revised downward or withdrawn entirely. Any such downward revision or withdrawal
could have an adverse effect on the market prices of the City's bonds.
    
 
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
 
                                      B-19
<PAGE>   709
 
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-20
<PAGE>   710
 
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-21
<PAGE>   711
 
  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-22
<PAGE>   712
 
  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 Investment Company 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
 
                                      B-23
<PAGE>   713
 
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 high-grade 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 high-grade 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, high-grade assets 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 high-grade 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 Internal Revenue 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 Standard & Poor's 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 having predominantly
  B         speculative characteristics with respect to capacity to pay interest and repay
  CCC       principal. 'BB' indicates the least degree of speculation and 'C' the highest.
  CC        While such debt will likely have some quality and protective characteristics,
  C         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.
</TABLE>
 
                                      B-25
<PAGE>   715
 
<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 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.
</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.
 
                                      B-26
<PAGE>   716
 
   
  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>
            Strong capacity to pay principal and interest. Issues determined to possess very
  SP-1      strong characteristics are a plus (+) designation.
 
            Satisfactory capacity to pay principal and interest, with some vulnerability to
  SP-2      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-27
<PAGE>   717
 
  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.
 
  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 senior debt obligations which have an original maturity not
  exceeding one year. Obligations relying upon support mechanisms such as
  letters-of-credit and bond 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 (or supporting institutions) have a superior
     ability for repayment of senior short-term debt obligations.
 
       Issuers rated Prime-2 (or supporting institutions) have a strong ability
     for repayment of senior short-term debt obligations.
 
                                      B-29
<PAGE>   719
 
       Issuers rated Prime-3 (or supporting institutions) have an acceptable
     ability for repayment of senior short-term debt obligations.
 
    Issuers rated Not Prime do not fall within any of the Prime rating
  categories.

* Interested persons of each respective Fund as defined in the Investment
Company Act.
 
  Each of the foregoing trustees of the Fund acts as a trustee for other
investment companies advised by the Adviser, and each of the foregoing officers
holds the same positions with other investment companies advised by the Adviser.
 
  The compensation of the officers and trustees who are affiliated persons (as
defined in the Investment Company Act) of the Adviser is paid by the Adviser,
and the compensation of the officers and trustees who are affiliated persons of
Van Kampen American Capital Distributors, Inc. or Van Kampen American Capital,
Inc. is paid by the respective entity. The Fund pays the compensation of all
other officers and trustees of the
 
                                      B-31

Fund. During the next year, the Fund expects to pay trustees who are not
affiliated persons of the Adviser, Van Kampen American Capital Distributors,
Inc. or Van Kampen American Capital, Inc. $2,500 per year, and $250 per meeting
of the Board of Trustees, plus expenses. Under the Fund's retirement plan,
trustees who are not affiliated with the Adviser, Van Kampen American Capital
Distributors, Inc. or Van Kampen American Capital, Inc., have at least ten years
of service and retire at or after attaining the age of 60, are eligible to
receive a retirement benefit equal to the annual retainer for each of the ten
years following such trustee's retirement. Under certain conditions, reduced
benefits are available for early retirement. Under the Fund's deferred
compensation plan, a trustee who is not affiliated with the Adviser, Van
American Capital Distributors, Inc. or Van Kampen American Capital, Inc. can
elect to defer receipt of all or a portion of the trustee's fees earned by such
trustee until such trustee's retirement. The deferred compensation earns a rate
of return determined by reference to the Fund or other Van Kampen Merritt mutual
funds advised by the Adviser as selected by the trustee. To the extent permitted
by the Investment Company Act, the Fund may invest in securities of other Van
Kampen Merritt mutual funds advised by the Adviser 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.

(1)     Messrs. Merritt and McDonnell, Trustees of each Fund during fiscal year
      1994, are affiliated persons of the Adviser and are not eligible for
      compensation or retirement benefits from the Funds.
    
 
   
(2)     The Registrant is Van Kampen Merritt Tax Free Fund (the "Trust") which
      currently is comprised of 8 sub-trusts, including the Fund. The amounts
      shown in this column are accumulated from the Aggregate Compensation of
      each of these 8 sub-trusts during such sub-trust's last completed fiscal
      year prior to the date of this Statement of Additional Information.
      Beginning in October 1994 each Trustee, except Messrs. Gaughan and Whalen,
      began deferring his entire aggregate compensation paid by the Fund. The
      total combined amount of deferred compensation (including interest)
      accrued with respect to each Trustee as of December 31, 1994 is as
      follows: Mr. Kennedy $14,737; Mr. Miller $14,553; Mr. Nelson $14,737 and
      Mr. Robinson $13,725.
    
 
   
(3)     The Retirement Plan commenced as of August 1, 1994 for the Fund. As of
      the end of the Fund's 1994 fiscal year, no amounts had been accrued for
      retirement benefits because such amounts were either zero or considered to
      be immaterial to the net assets of the Fund at such time. During the
      Fund's 1995 fiscal year, the Fund will accrue amounts for retirement
      benefits and include an amount, if any, for such Fund's 1994 fiscal year.
    
 
   
(4)     This is the estimated annual benefits payable per year for the 10-year
      period commencing in the year of such Trustee's retirement by a Fund
      assuming: the Trustee has 10 or more years of service on the Board of the
      Fund, retires at or after attaining the age of 60 and the annual retainer
      in the year prior to the Trustee's retirement is $2,500. Trustees retiring
      prior to the age of 60 or with fewer than 10 years of service for the Fund
      may receive reduced retirement benefits from such Fund.
    
 
   
(5)     The Fund Complex consists of 20 mutual funds advised by the Adviser. The
      amounts shown in this column are accumulated from the Aggregate
      Compensation of each of these 20 mutual funds in the Fund Complex during
      each fund's last completed fiscal year prior to the date of this Statement
      of

      other mutual funds and closed-end investment companies; however, with the
      exception of Messrs. Merritt, McDonnell and Whalen, such mutual funds and
      closed-end investment companies do not have the same trustees as the Fund
      Complex. Combining the Fund Complex with other mutual funds and investment
      companies advised by the Adviser, Mr. Whalen received Total Compensation
      of $161,850.

                     INVESTMENT ADVISORY AND OTHER SERVICES
 
INVESTMENT ADVISORY AGREEMENT
 
  Van Kampen Merritt Investment Advisory Corp. (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's principal office is
located at One Parkview Plaza, Oakbrook Terrace, Illinois 60181.
 
  The Adviser's principal office is located at One Parkview Plaza, Oakbrook
Terrace, Illinois 60181. The Adviser is a wholly-owned subsidiary of Van Kampen
American Capital, Inc., which in turn is a wholly-owned subsidiary of VK/AC
Holding, Inc. VK/AC Holding, Inc. is controlled, through the ownership of a
substantial majority of its common stock by The Clayton & Dubilier Private
Equity Fund IV Limited Partnership ("C&D L.P."), a Connecticut limited
partnership. C&D L.P. is managed by Clayton, Dubilier & Rice, Inc., a New York
based private investment firm. The General Partner of C&D L.P. is Clayton &
Dubilier Associates IV Limited Partnership ("C&D Associates L.P."). The general
partners of C&D Associates L.P. are Joseph L. Rice, III, B. Charles Ames,
William A. Barbe, Alberto Cribiore, Donald J. Gogel, Leon J. Hendrix, Jr.,
Hubbard C. Howe and Andrall E. Pearson, each of whom is a principal of Clayton,
Dubilier & Rice, Inc. In addition, certain officers, directors and employees of
Van Kampen American Capital, Inc. own, in the aggregate, not more than 6% of the
common stock of VK/AC Holding, Inc. and have the right to acquire, upon the
exercise of options, approximately an additional 10% of the common stock of
VK/AC Holding, Inc.
 
  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-33
<PAGE>   723
 
  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 sub-trust, 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 sub-trust
(or by the Fund's shareholders), and by the disinterested trustees in compliance
with the requirements of the Investment Company 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, 1994, the Fund recognized advisory expenses of
$0.
    
 
OTHER AGREEMENTS
 
  SUPPORT SERVICES AGREEMENT.  Under a support services agreement with the
Distributor the Fund receives support services for shareholders, including the
handling of all written and telephonic communications, except initial order
entry and other distribution related communications. Upon entering into such
agreement, the Fund realized a reduction in the fee which would have been paid
to the Transfer Agent if the Transfer Agent had provided such services. Payment
by the Fund for such services is made on cost basis for the employment of the
personnel and the equipment necessary to render the support services. The Fund,
and the other Van Kampen Merritt mutual funds distributed by the Distributor,
share such costs proportionately among themselves based upon their respective
net asset values.
 
   
  For the year ended December 31, 1994, the Fund recognized expenses of
approximately $0 representing the Distributor's cost of providing certain
support services.
    
 
   
  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 Merritt mutual funds
distributed by the Distributor in the cost to provide 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 Merritt funds based proportionally on their
respective net assets.
    
 
   
  For the year ended December 31, 1994, the Fund recognized expenses of
approximately $0 representing the Adviser's cost of providing accounting
services.
    
 
  LEGAL SERVICES AGREEMENT.  The Fund has entered into a Legal Services
Agreement pursuant to which Van Kampen American Capital, Inc. 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 Fund. 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. The
Fund, and the other Van Kampen Merritt mutual funds distributed by the
Distributor, share one half (50%) of such costs equally. The remaining one half
(50%) of such costs are allocated to specific funds based on specific time
allocations, or in the event services are attributable only to
 
                                      B-34

types of funds (i.e. closed-end or open-end), the relative amount of time spent
on each type of fund and then further allocated between funds of that type based
upon their respective net asset values.
 
   
  For the year ended December 31, 1994, the Fund recognized expenses of
approximately $0 representing Van Kampen American Capital, Inc.'s cost of
providing legal services.
    
 
CUSTODIAN AND INDEPENDENT AUDITORS
 
  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 auditors for the Fund are KPMG Peat Marwick LLP, Chicago,
Illinois. The selection of independent auditors 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 sub-trust.
 
                                      B-35
<PAGE>   725
 
   
  The trustees have adopted certain policies incorporating the standards of Rule
17e-1 issued by the SEC under the Investment Company 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 each of its sub-trusts, including the Fund, will be treated as
separate corporations for income tax purposes. The Fund may be subject to tax if
it fails to distribute net capital gains, or if its annual distributions, as a
percentage of its income, are less than the distributions required by tax laws.
 
  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 9.0% taxable yield at
current federal and state income tax rates to receive the same benefit.

* Combined Federal and State tax bracket was computed assuming that the investor
  is not subject to local income taxes, such as New York City taxes. Should a
  shareholder reside in a locality which imposes an income tax, the
  shareholder's taxable equivalent estimated current return would be greater
  than the taxable equivalent estimated current returns indicated in the table.
  The table does not reflect the New York State supplemental income tax based
  upon a taxpayer's New York State taxable income and New York State adjusted
  gross income. This supplemental tax results in an increased marginal State
  income tax rate to the extent a taxpayer's New York State adjusted gross
  income ranges between $100,000 and $150,000. In addition, the table does not
  reflect the amendments to the New York State income tax law that impose
  limitations on the deductibility of itemized deductions. The application of
  the New York State supplemental income tax and limitation on itemized
  deductions may result in a higher combined Federal, State and local tax rate
  than indicated in the table.
 
                                THE DISTRIBUTOR
 
  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 Van Kampen American Capital, Inc., which is a subsidiary of
VKM Holding, Inc., a Delaware corporation that is controlled through an
ownership of a substantial majority of its common stock, by The Clayton &
Dubilier Private Equity Fund IV Limited Partnership ("C & D L.P."), a
Connecticut limited partnership. In addition, certain officers, directors
 
                                      B-36
<PAGE>   726
 
and employees of Van Kampen American Capital, Inc., and its subsidiaries own, in
the aggregate not more than 6% of the common stock of VK/AC Holding, Inc. and
have the right to acquire, upon the exercise of options, approximately an
additional 10% of the common stock of VK/AC Holding, Inc. C & D L.P. is managed
by Clayton, Dubilier & Rice, Inc. Clayton & Dubilier Associates IV Limited
Partnership ("C & D Associates L.P.") is the general partner of C & D L.P.
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.
 
  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 Investment
Company 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, 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 banks 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 banks 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 sub-trust, 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 year ended December 31, 1994, the Fund has recognized expenses under
the Plans of $2,861, $29,906, and $686 for the Class A Shares, Class B Shares,
and Class C Shares, respectively, of which $0 and $0 represent payments to
financial intermediaries under the Selling Agreements for Class A Shares and
Class B Shares, respectively. For the year ended December 31, 1994, the Fund has
reimbursed the Distributor $0 and $0 for advertising expenses and $0 and $0 for
compensation of the Distributor's sales personnel for Class A Shares and Class B
Shares, respectively.

                            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
    
 
                                      B-37
<PAGE>   727
 
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. 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 total return including payment of the maximum sales charge with
respect to the Class A Shares for the five month period from July 29, 1994 (the
commencement of investment operations of the Fund) through December 31, 1994 was
(16.97%).
    
 
   
  The Fund's yield with respect to the Class A Shares for the 30 day period
ending December 30, 1994 (calculated in the manner described in the Prospectus
under the heading "Fund Performance") was 5.77%. The tax-equivalent yield with
respect to the Class A Shares for the 30 day period ending December 30, 1994
(calculated in the manner described in the Prospectus under the heading "Fund
Performance" and assuming a 41% tax rate) was 9.78%. The Fund's current
distribution rate with respect to the Class A Shares for the month ending
December 31, 1994 (calculated in the manner described in the Prospectus under
the heading "Fund Performance") was 5.86%.

Van Kampen Merritt New York Tax Free Income Fund
- --------------------------------------------------------------------------------

Notes to Financial Statements
December 31, 1994
- --------------------------------------------------------------------------------

1. Significant Accounting Policies

Van Kampen Merritt New York Tax Free Income Fund (the "Fund") was organized as a
subtrust of the Van Kampen Merritt Tax Free Fund, a Massachusetts 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 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.


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 less than 60 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" and "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.


D. Organizational Expenses and Initial Registration Costs-The Fund will 
reimburse Van Kampen American Capital Distributors, Inc. or its affiliates 
("VKAC") for costs incurred in connection with the Fund's organization and
initial registration in the amount of $120,000. These costs are being amortized
on a straight line basis over the 60 month period ending July 29, 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 and initial registration
costs 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, 1994, the Fund had an accumulated capital loss 
carryforward for tax purposes of $116,417 which will expire on December 31,
2002. Net realized gains or losses may differ for financial and tax reporting
purposes primarily as a result of post October 31 losses which are not 
recognized for tax purposes until the first day of the following fiscal 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.


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.

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, 1994, VKAC owned 100 shares each of Classes A, B and C.


3. Capital Transactions

The Fund has outstanding three classes of common shares, Classes A, B and C. 
There are an unlimited number of shares of each class without par value
authorized. 

At December 31, 1994, paid in surplus aggregated $3,023,505, $8,506,983 and
$172,496 for Classes A, B and C, respectively. For the period ended December 31,
1994, transactions were as follows:

Class B and C shares are offered without a front end sales charge, but are
subject to a contingent deferred sales charge (CDSC). The CDSC will be imposed
on most redemptions made within six years of the purchase for Class B and one
year of the purchase for Class C as detailed in the following schedule. The
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.

ITEM 27. INDEMNIFICATION.
    
 
     Please see Section 5.3 of the Registrant's Declaration of Trust (Exhibit
1(a)). Registrant's directors and officers are covered by an Errors and
Omissions Policy, Section 5 of the proposed Investment Advisory Agreement
between the Registrant and Van Kampen American Capital Investment Advisory Corp.
(the "Adviser") provides that, in the absence of willful misfeasance, bad faith,
gross negligence or reckless disregard of the obligations or duties under the
Investment Advisory Agreement on the part of the Adviser, the Adviser shall not
be liable to the Registrant or to any shareholder for any act or omission in the
course of or connected in any way with rendering services or for any losses that
may be sustained in the purchase, holding or sale of any security. The
Distribution Agreement provides that the Registrant shall indemnify the
Distributor and certain persons related thereto for any loss or liability
arising from any alleged misstatement of a material fact (or alleged omission to
state a material fact) contained in, among other things, the Registration
Statement or Prospectus except to the extent the misstated fact or omission was
made in reliance upon information provided by or on behalf of such Distributor.
(See Section 7 of the Distribution Agreement.)
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant and the investment adviser and distributor pursuant to the foregoing
provisions or otherwise, the Registrant has been advised that in the opinion of
the Securities
 
                                       C-6
<PAGE>   743
 
and Exchange Commission such indemnification is against public policy as
expressed in the Act and is, therefore, unenforceable. In the event that a claim
for indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer, or controlling
person of the Registrant and the principal underwriter in connection with the
successful defense of any action, suit or proceeding) is asserted against the
Registrant by such director, officer or controlling person or the Distributor in
connection with the shares being registered, the Registrant will, unless in the
opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.
 
ITEM 28. BUSINESS AND OTHER CONNECTIONS OF INVESTMENT ADVISER.
 
     See "Investment Advisory Services" in the Prospectus and "Officers and
Trustees" in the Statement of Additional Information for information regarding
the business of the Adviser. For information as to the business, profession,
vocation and employment of a substantial nature of directors and officers of the
Adviser reference is made to the Adviser's current Form ADV (File No. 801-18161)
filed under the Investment Advisers Act of 1940, as amended, incorporated herein
